  • 본 논고는 19세기 이후 형성된 서화(書畫)의 유통과 확산의 양상을 당시 활발히 제작된 장식병풍 중 하나인 <백선도(百扇圖)>의 예를 통해 살펴본 글이다. 백선도는 화면에 다양한 형태의 부채를 겹쳐서 배치하고 각각의 선면(扇面) 안에 여러 종류의 화제(畫題)를 그린 것을 말한다. 부채와 선면화(扇面畫)라는 소재는 이전부터 존재하였지만 장식용 회화의 소재로 등장한 것은 19세기 이후로, 호사취미 경향을 반영하여 주로 병풍(屛風)으로 활발히 제작되었다. 지난 2016년 국립중앙박물관 특별전 '미술 속 도시, 도시 속 미술'에서 독일로텐바움세계문화예술박물관 소장 <백선도>가 새로이 소개된 바 있다. 6폭으로 구성된 이 병풍에는 한 폭 당 5개 이상의 다양한 종류의 부채들이 등장하고 각 부채 면에는 단순히 채색한 것 뿐 아니라 다양한 화목(畫目)의 그림들이 남아있다. 무엇보다 이 작품을 주목해야 하는 것은 국립중앙박물관에 동일한 초본(草本)이 전하고 있기 때문이다. 19세기에 들어서면서 이전의 왕실이나 사대부들이 사적인 공간에서 향유하였던 서화(書畫)는 민간으로 확산되었고 시장을 통한 유통의 단계로 넓어졌다. 집안을 꾸미고 장식하는 풍조에 따라 화려한 장식그림들이 선호되었고, 한 폭에 다양한 형태의 화면과 다채로운 畫目(화목)의 그림을 그려 완성하는 백납도병풍 제작이 성행하였다. 로텐바움박물관 소장 한국 컬렉션의 상당수는 독일 주재 조선국 총영사이자 독일의 사업가였던 하인리히 콘스탄틴 에두아르 마이어(Heinrich Constantin Eduard Meyer, 1841~1926)의 수집품이다. 그는 1890년대 후반부터 1905년까지 조선과 독일을 오가며 다양한 유물들을 수집하여 독일에 돌아가 1909년까지 순차적으로 수집품을 로텐바움박물관에 전달하였으며, <백선도>도 그 중 하나이다. 새롭고 장식미가 돋보이는 <백선도>는 조선에 들어와 있던 외국인들의 이목을 집중시키기에 충분했을 것이다. 로텐바움박물관 소장 <백납도>는 제2폭의 뒷면에 "동현(銅峴)"이라는 지명이 적힌 종이조각이 거꾸로 붙어있어 흥미를 끈다. 동현은 지금의 서울 을지로 1가와 을지로2가 사이에 위치했던 곳이며, 조선시대에는 도화서(圖畫署)를 비롯한 혜민서(惠民署)·장악원(掌樂院) 등의 관청과 시전(市廛)이 있어 가내수공업이 성하던 지역이었다. 실제로 1900년대 초 이곳에는 서화를 유통하는 상점들이 자리잡고 있었기 때문에, 마이어가 수집했던 서화들의 구입처가 동현에 위치했었을 가능성은 매우 높다고 하겠다. 로텐바움박물관 소장 <백선도>는 총 6폭의 병풍으로, 1980년대에 한국 서화 소장품들을 수리하는 과정에서 현재의 모습을 갖춘 것으로 보인다. 국립중앙박물관 소장 <백선도 초본>은 1945년부터 1950년 사이 국립민족박물관에 입수된 작품이다. <백선도 초본>은 총 7점으로, 7점 중 6면 화면의 여백에 화면의 순서까지 정해져 있어 본래 총 8폭 병풍용 초본임을 알 수 있다. 한 화면에는 5개 이상의 다양한 접선(摺扇)과 단선(團扇)들이 배열해있는데, 작은 장식에서부터 부챗살의 문양까지 초본부터 사실적으로 묘사되었음을 볼 수 있다. 여기에 '석간주(石間朱)', '홍(紅)', '묵(墨)', '청(靑)' 등과 같이 부채에 들어갈 색 대부분을 지정하고, 빈 부채에는 '유(油)'라고 적거나 비워두었으며 이 중 10개의 부채에는 화훼초충도(花卉草蟲圖)나 고사인물도의 밑그림이 남아있다. 이를 실제 로텐바움박물관 소장 <백선도>와 비교하면 화면의 크기와 비례까지 정확하게 일치하고 있어, 초본의 매뉴얼을 그대로 따르고 있음을 보여준다. 이 작품의 펼쳐진 부채 면에는 산수, 고사인물, 화조, 영모, 초충, 어해 등 다양한 장르의 그림이 그려져 있는데 화접도(花蝶圖)나 어해도(魚蟹圖) 등은 19세기 유행하였던 소재로 당시 화단의 경향을 잘 보여준다. 이 작품에서 주목할 것은 김홍도(金弘道)의 전형적인 화풍을 연상시키는 장면들이 다수 포함되어 있다는 점이다. 이는 지금까지 알려진 백선도나 백납도에서는 찾아보기 어려운 특징이다. 서원아집도(西園雅集圖)는 상대적으로 제한된 작은 화면에 그려야 하는 백납도나 백선도의 특성상 잘 다루지 않는 소재로, 국립중앙박물관 소장 김홍도의 <서원아집도>병풍과 화면의 구성이나 화풍 모두 매우 흡사하다. 더구나 <백선도>병풍의 몇몇 장면은 김홍도의 작품 중에서도 1796년작 《병진년화첩(丙辰年畫帖)》과 유사한 화면들을 다수 발견할 수 있어 흥미롭다. <사인암(舍人巖)>과 흡사한 산수도(山水圖)를 비롯하여 <서원아집도>, <쌍치도(雙雉圖)> 등에서 김홍도 화풍을 연상시킨다. 따라서 부채 속 그림을 그린 인물은 김홍도 화풍의 영향을 받은 직업화가일 것으로 보이며, 작가는 《병진년화첩》을 직접 감상한 적이 있거나, 서화시장에 《병진년화첩》을 베껴 그린 부본(副本)이 유통되었을 가능성이 매우 높다. 현재까지 알려진 병풍으로 된 백선도는 10점 내외인 것으로 파악되며, 이 작품들을 비교해보면 화면의 구성이 부채 1개 정도 차이가 있거나 비례와 좌우가 바뀌었을 뿐 화면구성이 매우 유사함을 찾아볼 수 있다. 이처럼 일정한 패턴의 화면구성은 같은 시기 민간에서 성행한 책가도(冊架圖)에서도 찾아볼 수 있는 특징으로, 19세기 서화의 수요층이 넓어짐에 따라 세밀한 표현과 화려한 장식성이 요구되는 회화들의 대량 제작을 위한 초본이 존재했음을 보여준다. 특히 도안이 복잡하여 범본이 필요한 곽분양행락도나 요지연도, 백동자도, 해학반도도 등의 규모가 큰 장식병풍에서 적극 활용되었으며, 실제 남아있는 작품에서 몇 가지의 도상들이 반복하여 등장하고 있어 초본을 참고했던 흔적을 찾아볼 수 있다. 시장의 수요에 맞추어 대량 제작할 수 있는 초본 활용이 성행했던 당시의 경향은 화면을 다채로운 부채들로 채우고 그 부채 면에 각기 다른 그림을 그려야하는 백선도 제작에 있어서도, 초본을 요긴하게 사용했음을 보여준다. 더구나 테두리를 그은 후 다양한 화목의 그림을 담는 백납도에 비해 백선도는 다양한 형태의 부채들을 먼저 그려야하는 공정을 거쳐야 했기 때문에, 대량 제작이 어렵고 그만큼 남아있는 작품이 상대적으로 적은 원인으로 생각된다. 이처럼 로텐바움박물관 소장 <백선도> 병풍과 국립중앙박물관 <백선도 초본>은 새로운 화풍이 수용되어 시도되었던 조선 말기 화단의 경향을 잘 보여주는 예라 하겠다. 다수의 백선도들이 박기준의 작품과 유사한 화풍과 화면 구성 보이는 것에 비해, 김홍도의 영향이 분명히 드러나는 매우 이례적인 예라는 점에서 앞으로도 더욱 심층적인 분석이 요구되는 작품이다.

  • The wall shear stress in the vicinity of end-to end anastomoses under steady flow conditions was measured using a flush-mounted hot-film anemometer(FMHFA) probe. The experimental measurements were in good agreement with numerical results except in flow with low Reynolds numbers. The wall shear stress increased proximal to the anastomosis in flow from the Penrose tubing (simulating an artery) to the PTFE: graft. In flow from the PTFE graft to the Penrose tubing, low wall shear stress was observed distal to the anastomosis. Abnormal distributions of wall shear stress in the vicinity of the anastomosis, resulting from the compliance mismatch between the graft and the host artery, might be an important factor of ANFH formation and the graft failure. The present study suggests a correlation between regions of the low wall shear stress and the development of anastomotic neointimal fibrous hyperplasia(ANPH) in end-to-end anastomoses. 30523 T00401030523 ^x Air pressure decay(APD) rate and ultrafiltration rate(UFR) tests were performed on new and saline rinsed dialyzers as well as those roused in patients several times. C-DAK 4000 (Cordis Dow) and CF IS-11 (Baxter Travenol) reused dialyzers obtained from the dialysis clinic were used in the present study. The new dialyzers exhibited a relatively flat APD, whereas saline rinsed and reused dialyzers showed considerable amount of decay. C-DAH dialyzers had a larger APD(11.70$\pm$1.32mmHg/min)compared to CF dialyzers(4.32$\pm$0.55mmHg/min)(p<0.05). However, there was no observable difference in the UFR between the two dialyzers. Neither APD nor UFR showed any significant increase with an increasing number of reuses for up to more than 20reuses. A substantial number of failures observed in APD(larger than 20mmHe/min)on the reused dialyzers(2 out of 40 CP and S out 26 C-DAK) were attributed to the Possible damage on the fibers. The CF 15-11 HFDs which failed APD test did not show changes in the UFR compared to normal dialyzers indicating that APD is a more sensitive test than UFR test to evaluate the integrity of the fibers. 30527 T00401030527 ^x For quantitative measurement of reflected light from a clinical diagnostic strip, a prototype old reflectance photometer was designed. The strip loader and cassette were made to obtain more accurate reflectance parameters. The strip was illuminated at 45˚c through optical fiber and the intensity of reflected light was determined at rectanguLat angle using a photodiode. The kubelka-munk coefficient and reflection optical density were determined ar four different wavelengths(500, 550, 570 and 610nm) for blood glucose strip. For higher concentration than 300mg/41 about glucose, a saturation state of abforbance was observed at 500, 550 and 570nm. The correlation between glucose concentration and parameters was the best at 610nm. 30535 T00401030535 ^x Radiation-induced fibrosarcoma tumors were grown on the flanks of C3H mice. The mice were divided into two groups. One group was injected with Photofrin II, intravenously (2.5mg/kg body weight). The other group received no Photofrin II. Mice from both groups were irradialed for approximately 15 minutes at 100, 300, or 500 mW/cm2 with the argon (488nm/514.5 nm), dye(628nm) and gold vapor (pulsed 628 nm) laser light. A photosensitizer behaved as an added absorber. Under our experimental conditions, the presence of Photolfrin II increased surface temperature by at least 40% and the temperature rise due to 300 mW/cm2 irradiation exceeded values for hyperthermia. Light and temperature distributions with depth were estimated by a computer model. The model demonstrated the influence of wavelength on the thermal process and proved to be a valuable tool to investigate internal temperature rise. 30536 T00401030536 ^x We investigated the structural geometry of thirty-eight Korean femurs. The purpose of this study is to identify major geometrical differences between Korean femurs 3nd others that we believe belong to Caucasians so that we would be able to get insights into the femoral component design that fits Asians including Koreans. We utilized computerized tomography (CT) images of femurs extracted from cadavers. The CT images were transformed into bitmap data by using a film scanner, and then analyzed by using a commercially available software called Image v.1.0 and a Macintosh IIci computer.The resulting data were compared with already published data. The major results show that the geometry of the Korean femurs is significantly different from that of Caucasians: (1) the anteversion angle and the canal flare index are greater by the amount of approximately 8˚ and 0.5, respectively, (2) the shape of the isthmus cross section is more round, and (3) the distance between the teaser trochanter and the proximal border of the isthmus is shelter by about 15 mm. The results suggested that the femoral component suitable for Asians should be different from the currently-used components designed and manufactured mostly by European or American companies. 30537 T00401030537 ^x It is well known that nonlinear propagation characteristics of the wave in the tissue may give very useful information for the medical diagnoisis. In this paper, a new method to detect nonlinear propagation characteristics of the internal vibration in the tissue for the low frequency mechanical vibration by using bispectral analysis is proposed. In the method, low frequency vibration of f0( = 100Hz) is applied on the surface of the object, and the waveform of the internal vibration x (t) is measured from Doppler frequency modulation of silmultaneously transmitted probing ultrasonic waves. Then, the bispectra of the signal x (t) at the frequencies (f0, f0) and (f0, 2f0) are calculated to estimate the nonlinear propagation characteristics as their magnitude ratio, w here since bispectrum is free from the gaussian additive noise we can get the value with high S/N. Basic experimental system is constructed by using 3.0 MHz probing ultrasonic waves and the several experiments are carried out for some phantoms. Results show the superiority of the proposed method to the conventional method using power spectrum and also its usefulness for the tissue characterization. 30541 T00401030541 ^x This paper describes the implementation of a computerized radial pulse diagnosis by aids of a clinical expert. On this base, we composed of the radial pulse diagnosis system in korean traditional medicine. The system composed of a radial pulse wave detection system and a radial pulse diagnosis system. With a detection system, we detected Inyoung and Cheongu radial pulse wave and processed it. Then, we have got the characteristic parameters of radial pulse wave and also quantified that according to the method of Inyoung-Cheongu Comparison Radial Pulse Diagnosis. We defined the jugement standard of radial pulse diagnosis system and then we confirmed the possibility for realization of automatic radial pulse diagnosis in korean traditional medicine. 30545 T00401030545 ^x Microspheres are expected to be applied to biomedical areas such as solid-phase immunoassays, drug delivery systems, immunomagnetic cell separation. To synthesize microspheres for biomedical application, "two stage shot growth method" was developed. The uniformity ratio of synthesized microspheres was always smaller than 1.05. And the surface charge density (or the number of ionizable functional groups) of the microspheres synthesized by "two stage shot growth method" was 6~13 times higher than that of the microspheres synthesized by conventional seeded batch copolymerization. As a previous step for biomedical application, adsorption experiments of bovine albumin on microspheres were carried out under various conditions. The maximum adsorbed amount was obtained in the neighborhood of pH 4.5. Isoelectric point of bovine albumin is pH 5.0, so experimental result shows that it shifted to acid area. The adsorption isotherm was obtained, the plateau region was always reached at 2.Og/L (bulk concentration of bovine albumin).The effect of the kind and the amount of surface functional group was also examined. 30575 T00401030575 ^x A medical image workstation was developed using multimedia technique. The system based on PC-486DX was designed to acquire medical images produced by medical imaging instruments and related audio information, that is, doctors' reporting results. Input information was processed and analyzed, then the results were presented in the form of graph and animation. All the informations of the system were hierarchically related with the image as the apex. Processing and analysis algorithms were implemented so that the diagnostic accuracy could be improved. The diagnosed information can be transferred for patient diagnosis through LAN(local area network). 30592 T00401030592 ^x In the conventional infrared imaging system, complex infrared lens systems are usually used for directing collimated narrow infrared beams into the high speed 2-dimensional optic scanner. In this paper, a simple reflective infrared optic system with a 2-dimensional optic scanner is proposed for the realization of medical infrared thermography system. It has been experimentally proven that the intfrared thermography system composed of the proposed optic system has the temperature resolution of 0.1˚c under the spatial resolution of lmrad, the image matrix size of 256 X 240, and tile imaging time of 4 seconds. 30593 T00401030593 ^x In this paper, MIIS (Medical Image Information System) has been designed and implemented using INGRES RDBMS, which is based on a client/server architecture. The implemented system allows users to register and retrieve patient information, medical images and diagnostic reports. It also provides the function to display these information on workstation windows simultaneously by using the designed menu-driven graphic user interface. The medical image compression/decompression techniques are implemented and integrated into the medical image database system for the efficient data storage and the fast access through the network. 30594 T00401030594 ^x In this paper, computerized BEAM was implemented for the space domain analysis of EEG. Trans-formation from temporal summation to two-dimensional mappings is formed by 4 nearest point inter-polaton method. Methods of representation of BEAM are two. One is dot density method which classify brain electrical potential 9 levels by dot density of gray levels and the other is colour method which classify brain electrical 12 levels by red-green colours. In this BEAM, instantaneous change and average energy distribution over any arbitrary time interval of brain electrical activity could be observed and analyzed easily. In the frequency domain, the distribution of energy spectrum of a special band can easily be distinguished normality and abnormality. 30608 T00401030608 ^x Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer. The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with fwd complete blood count analyzers(Sysmex NE-8000 and Coulter STKS) for unidirectional data tansmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology. 30609 T00401030609 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed a composite that is consisted of calcium phosphate and collagen. To use as the structural matrix of the composite, collagen was purified from human umbilical cord. The obtained collagen was treated by pepsin to remove telopeptides, and finally, the immune-free atelocollagen was produced: The cross linked atelocollagen was highly resistant to the collagenase induced collagenolysis. The cross linked collagen demonstrated an improved tensile strength. 30618 T00401030618 ^x This paper is a study on the design of adptive filter for QRS complex detection. We propose a simple adaptive algorithm to increase capability of noise cancelation in QRS complex detection with two stage adaptive filter. At the first stage, background noise is removed and at the next stage, only spectrum of QRS complex components is passed. Two adaptive filters can afford to keep track of the changes of both noise and QRS complex. Each adaptive filter consists of prediction error filter and FIR filter The impulse response of FIR filter uses coefficients of prediction error filter. The detection rates for 105 and 108 of MIT/BIH data base were 99.3% and 97.4% respectively. 30619 T00401030619 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed and produced a composite that is consisted of calcium phosphate and collagen. Human umbilical cord origin pepsin treated type I atelocollagen was used as the structural matrix, by which sintered or non-sintered carbonate apatite was encapsulated to form an inorganic-organic composite. With cross linking atelocollagen by UV ray irradiation, the resistance to both compressive and tensile strength was increased. Collagen degradation by the collagenase induced collagenolysis was also decreased. 30620 T00401030620 ^x We have developed a monoleaflet polymer valve as an inexpensive and viable alternative, especially for short-term use in the ventricular assist device or total artificial heart. The frame and leaflet of the polymer valve were made from polyurethane, To evaluate the hemodynamic performance of the polymer valve a comparative study of flow dynamics past a polymer valve and a St. Jude Medical prosthetic valve under physiological pulsatile flow conditions in vitro was made. Comparisons between the valves were made on the transvalvular pressure drop, regurgitation volume and maximum valve opening area. The polymer valve showed smaller regurgitation volume and transvalvular pressure drop compared to the mechanical valve at higher heart rate. The results showed that the functional characteristics of the polymer valve compared favorably with those of the mechanical valve at higher heart rate. 30621 T00401030621 ^x Explosive evaporative removal process of biological tissue by absorption of a CW laser has been simulated by using gelatin and a multimode Nd:YAG laser. Because the point of maximun temperature of laser-irradiated gelatin exists below the surface due to surface cooling, evaporation at the boiling temperature is made explosively from below the surface. The important parameters of this process are the conduction loss to laser power absorption (defined as the conduction-to-laser power parameter, Nk), the convection heat transfer at the surface to conduction loss (defined as Bi), dimensionless extinction coefficient (defined as Br.), and dimensionless irradiation time (defined as Fo). Dependence of Fo on Nk and Bi has been observed by experiment, and the results have been compared with the numerical results obtained by solving a 2-dimensional conduction equation. Fo and explosion depth (from the surface to the point of maximun temperature) are increased when Nk and Bi are increased.To find out the minimum laser power for explosive evaporative removal process, steady state analysis has been also made. The limit of Nk to induce evaporative removal, which is proportional to the inverse of the laser power, has been obtained. 30622 T00401030622 ^x N1 and N2 gross neural action potentials were measured from the round window of the guinea pig cochlea at the onset of the acoustic stimuli. N1-N2 audiograms were made by means of regulating stimulant intensities in order to produce constant N1-N2 potentials as criteria for different input tone pip frequencies. The lowest threshold was measured with an input tone pip I5 dB SPL in intensity and 12 KHz in frequency when the animal was in normal physiological condition. The procedure of experimental measurements is explained in detail. This experimental approach is very useful for the investigation of the Cochlear function. Both noN1inear and active functions of the Cochlea can be monitored by N1-N2 audiograms. 30623 T00401030623 ^x In electrical impedance tomography(EIT), we use boundary current and voltage measurements toprovide the information about the cross-sectional distribution of electrical impedance or resistivity. One of the major problems in EIT has been the inaccessibility of internal voltage or current data in finding the internal impedance values. We propose a new image reconstruction method using internal current density data measured by NMR. We obtained a two-dimensional current density distribution within a phantom by processing the real and imaginary MR images from a 4.77 NMR machine. We implemented a resistivity mage reconstruction algorithm using the finite element method and sensitivity matrix. We presented computer simulation results of the mage reconstruction algorithm and furture direction of the research. 30624 T00401030624 ^x A new method of digital image analysis technique for discrimination of cancer cell was presented in this paper. The object image was the Thyroid eland cells image that was diagnosed as normal and abnormal (two types of abnormal: follicular neoplastic cell, and papillary neoplastic cell), respectively. By using the proposed region segmentation algorithm, the cells were segmented into nucleus. The 16 feature parameters were used to calculate the features of each nucleus. A9 a consequence of using dominant feature parameters method proposed in this paper, discrimination rate of 91.11% was obtained for Thyroid Gland cells. 30625 T00401030625 ^x An electrical stimulator was designed to induce locomotion for paraplegic patients caused by central nervous system injury. Optimal stimulus parameters, which can minimize muscle fatigue and can achieve effective muscle contraction were determined in slow and fast muscles in Sprague-Dawley rats. Stimulus patterns of our stimulator were designed to simulate electromyographic activity monitored during locomotion of normal subjects. Muscle types of the lower extremity were classified according to their mechanical property of contraction, which are slow muscle (msoleus m.) and fast muscle (medial gastrocneminus m., rectus femoris m., vastus lateralis m.). Optimal parameters of electrical stimulation for slow muscles were 20 Hz, 0.2 ms square pulse. For fast muscle, 40 Hz, 0.3 ms square pulse was optimal to produce repeated contraction. Higher stimulus intensity was required when synergistic muscles were stimulated simultaneously than when they were stimulated individually. Electrical stimulation for each muscle was designed to generate bipedal locomotion, so that individual muscles alternate contraction and relaxation to simulate stance and swing phases. Portable electrical stimulator with 16 channels built in microprocessor was constructed and applied to paraplegic patients due to lumbar cord injury. The electrical stimulator restored partially gait function in paraplegic patients. 30626 T00401030626 ^x Two-Dimensional modelling of the Cochlear biomechanics is presented in this paper. The Laplace partial differential equation which represents the fluid mechanics of the Cochlea has been transformed into two-dimensional electrical transmission line. The procedure of this transformation is explained in detail. The comparison between one and two dimensional models is also presented. This electrical modelling of the basilar membrane (BM) is clearly useful for the next approach to the further. Development of active elements which are essential in the producing of the sharp tuning of the BM. This paper shows that two-dimension model is qualitatively better than one-dimensional model both in amplitude and phase responses of the BM displacement. The present model is only for frequency response. However because the model is electrical, the two-dimensional transmission line model can be extended to time response without any difficult. 30627 T00401030627 ^x A method has been proposed for the fully automatic detection of left ventricular endocardial boundary in 2D short axis echocardiogram using geometric model. The procedure has the following three distinct stages. First, the initial center is estimated by the initial center estimation algorithm which is applied to decimated image. Second, the center estimation algorithm is applied to original image and then best-fit elliptic model estimation is processed. Third, best-fit boundary is detected by the cost function which is based on the best-fit elliptic model. The proposed method shows effective result without manual intervention by a human operator. 30628 T00401030628 ^x The intelligent trajectory control method that controls moving direction and average velocity for a prosthetic arm is proposed by pattern recognition and force estimations using EMG signals. Also, we propose the real time trajectory planning method which generates continuous accelleration paths using 3 stage linear filters to minimize the impact to human body induced by arm motions and to reduce the muscle fatigue. We use combination of MLP and fuzzy filter for pattern recognition to estimate the direction of a muscle and Hogan's method for the force estimation. EMG signals are acquired by using a amputation simulator and 2 dimensional joystick motion. The simulation results of proposed prosthetic arm control system using the EMf signals show that the arm is effectively followed the desired trajectory depended on estimated force and direction of muscle movements. 30638 T00401030638 ^x A new neural network architecture for the recognition of patterns from images is proposed, which is partially based on the results of physiological studies. The proposed network is composed of multi-layers and the nerve cells in each layer are connected by spatial filters which approximate receptive fields in optic nerve fields. In the proposed method, patterns recognition for complicated images is carried out using global features as well as local features such as lines and end-points. A new generating method of matched filers representing global features is proposed in this network. 30659 T00401030659 ^x An implementation scheme of the magnetic nerve stimulator using a switching mode power supply is proposed. By using a switching mode power supply rather than a conventional linear power supply for charging high voltage capacitors, the weight and size of the magnetic nerve stimulator can be considerably reduced. Maximum output voltage of the developed magnetic nerve stimulator using the switching mode power supply is 3, 000 volts and switching time is about 100 msec. Experimental results or human nerve stimulations using the developed stimulator are presented. 30768 T00401030768 ^x In this paper, we describe the design methodology and specifications of the developed module-based bedside monitors for patient monitoring. The bedside monitor consists of a main unit and module cases with various parameter modules. The main unit includes a 12.1" TFT color LCD, a main CPU board, and peripherals such as a module controller, Ethernet LAN card, video card, rotate/push button controller, etc. The main unit can connect at maximum three module cases each of which can accommodate up to 7 parameter modules. They include the modules for electrocardiograph, respiration, invasive blood pressure, noninvasive blood pressure, temperature, and SpO2 with Plethysmograph.SpO2 with Plethysmograph.

  • The wall shear stress in the vicinity of end-to end anastomoses under steady flow conditions was measured using a flush-mounted hot-film anemometer(FMHFA) probe. The experimental measurements were in good agreement with numerical results except in flow with low Reynolds numbers. The wall shear stress increased proximal to the anastomosis in flow from the Penrose tubing (simulating an artery) to the PTFE: graft. In flow from the PTFE graft to the Penrose tubing, low wall shear stress was observed distal to the anastomosis. Abnormal distributions of wall shear stress in the vicinity of the anastomosis, resulting from the compliance mismatch between the graft and the host artery, might be an important factor of ANFH formation and the graft failure. The present study suggests a correlation between regions of the low wall shear stress and the development of anastomotic neointimal fibrous hyperplasia(ANPH) in end-to-end anastomoses. 30523 T00401030523 ^x Air pressure decay(APD) rate and ultrafiltration rate(UFR) tests were performed on new and saline rinsed dialyzers as well as those roused in patients several times. C-DAK 4000 (Cordis Dow) and CF IS-11 (Baxter Travenol) reused dialyzers obtained from the dialysis clinic were used in the present study. The new dialyzers exhibited a relatively flat APD, whereas saline rinsed and reused dialyzers showed considerable amount of decay. C-DAH dialyzers had a larger APD(11.70${\pm}$1.32mmHg/min)compared to CF dialyzers(4.32${\pm}$0.55mmHg/min)(p<0.05). However, there was no observable difference in the UFR between the two dialyzers. Neither APD nor UFR showed any significant increase with an increasing number of reuses for up to more than 20reuses. A substantial number of failures observed in APD(larger than 20mmHe/min)on the reused dialyzers(2 out of 40 CP and S out 26 C-DAK) were attributed to the Possible damage on the fibers. The CF 15-11 HFDs which failed APD test did not show changes in the UFR compared to normal dialyzers indicating that APD is a more sensitive test than UFR test to evaluate the integrity of the fibers. 30527 T00401030527 ^x For quantitative measurement of reflected light from a clinical diagnostic strip, a prototype old reflectance photometer was designed. The strip loader and cassette were made to obtain more accurate reflectance parameters. The strip was illuminated at 45˚c through optical fiber and the intensity of reflected light was determined at rectanguLat angle using a photodiode. The kubelka-munk coefficient and reflection optical density were determined ar four different wavelengths(500,550,570 and 610nm) for blood glucose strip. For higher concentration than 300mg/41 about glucose, a saturation state of abforbance was observed at 500,550 and 570nm. The correlation between glucose concentration and parameters was the best at 610nm. 30535 T00401030535 ^x Radiation-induced fibrosarcoma tumors were grown on the flanks of C3H mice. The mice were divided into two groups. One group was injected with Photofrin II, intravenously (2.5mg/kg body weight). The other group received no Photofrin II. Mice from both groups were irradialed for approximately 15 minutes at 100,300, or 500 mW/cm2 with the argon (488nm/514.5 nm), dye(628nm) and gold vapor (pulsed 628 nm) laser light. A photosensitizer behaved as an added absorber. Under our experimental conditions, the presence of Photolfrin II increased surface temperature by at least 40% and the temperature rise due to 300 mW/cm2 irradiation exceeded values for hyperthermia. Light and temperature distributions with depth were estimated by a computer model. The model demonstrated the influence of wavelength on the thermal process and proved to be a valuable tool to investigate internal temperature rise. 30536 T00401030536 ^x We investigated the structural geometry of thirty-eight Korean femurs. The purpose of this study is to identify major geometrical differences between Korean femurs 3nd others that we believe belong to Caucasians so that we would be able to get insights into the femoral component design that fits Asians including Koreans. We utilized computerized tomography (CT) images of femurs extracted from cadavers. The CT images were transformed into bitmap data by using a film scanner, and then analyzed by using a commercially available software called Image v.1.0 and a Macintosh IIci computer.The resulting data were compared with already published data. The major results show that the geometry of the Korean femurs is significantly different from that of Caucasians: (1) the anteversion angle and the canal flare index are greater by the amount of approximately 8˚ and 0.5, respectively, (2) the shape of the isthmus cross section is more round, and (3) the distance between the teaser trochanter and the proximal border of the isthmus is shelter by about 15 mm. The results suggested that the femoral component suitable for Asians should be different from the currently-used components designed and manufactured mostly by European or American companies. 30537 T00401030537 ^x It is well known that nonlinear propagation characteristics of the wave in the tissue may give very useful information for the medical diagnoisis. In this paper, a new method to detect nonlinear propagation characteristics of the internal vibration in the tissue for the low frequency mechanical vibration by using bispectral analysis is proposed. In the method, low frequency vibration of f0( = 100Hz) is applied on the surface of the object, and the waveform of the internal vibration x (t) is measured from Doppler frequency modulation of silmultaneously transmitted probing ultrasonic waves. Then, the bispectra of the signal x (t) at the frequencies (f0, f0) and (f0, 2f0) are calculated to estimate the nonlinear propagation characteristics as their magnitude ratio, w here since bispectrum is free from the gaussian additive noise we can get the value with high S/N. Basic experimental system is constructed by using 3.0 MHz probing ultrasonic waves and the several experiments are carried out for some phantoms. Results show the superiority of the proposed method to the conventional method using power spectrum and also its usefulness for the tissue characterization. 30541 T00401030541 ^x This paper describes the implementation of a computerized radial pulse diagnosis by aids of a clinical expert. On this base, we composed of the radial pulse diagnosis system in korean traditional medicine. The system composed of a radial pulse wave detection system and a radial pulse diagnosis system. With a detection system, we detected Inyoung and Cheongu radial pulse wave and processed it. Then, we have got the characteristic parameters of radial pulse wave and also quantified that according to the method of Inyoung-Cheongu Comparison Radial Pulse Diagnosis. We defined the jugement standard of radial pulse diagnosis system and then we confirmed the possibility for realization of automatic radial pulse diagnosis in korean traditional medicine. 30545 T00401030545 ^x Microspheres are expected to be applied to biomedical areas such as solid-phase immunoassays, drug delivery systems, immunomagnetic cell separation. To synthesize microspheres for biomedical application, "two stage shot growth method" was developed. The uniformity ratio of synthesized microspheres was always smaller than 1.05. And the surface charge density (or the number of ionizable functional groups) of the microspheres synthesized by "two stage shot growth method" was 6~13 times higher than that of the microspheres synthesized by conventional seeded batch copolymerization. As a previous step for biomedical application, adsorption experiments of bovine albumin on microspheres were carried out under various conditions. The maximum adsorbed amount was obtained in the neighborhood of pH 4.5. Isoelectric point of bovine albumin is pH 5.0, so experimental result shows that it shifted to acid area. The adsorption isotherm was obtained, the plateau region was always reached at 2.Og/L (bulk concentration of bovine albumin).The effect of the kind and the amount of surface functional group was also examined. 30575 T00401030575 ^x A medical image workstation was developed using multimedia technique. The system based on PC-486DX was designed to acquire medical images produced by medical imaging instruments and related audio information, that is, doctors' reporting results. Input information was processed and analyzed, then the results were presented in the form of graph and animation. All the informations of the system were hierarchically related with the image as the apex. Processing and analysis algorithms were implemented so that the diagnostic accuracy could be improved. The diagnosed information can be transferred for patient diagnosis through LAN(local area network). 30592 T00401030592 ^x In the conventional infrared imaging system, complex infrared lens systems are usually used for directing collimated narrow infrared beams into the high speed 2-dimensional optic scanner. In this paper, a simple reflective infrared optic system with a 2-dimensional optic scanner is proposed for the realization of medical infrared thermography system. It has been experimentally proven that the intfrared thermography system composed of the proposed optic system has the temperature resolution of 0.1˚c under the spatial resolution of lmrad, the image matrix size of 256 X 240, and tile imaging time of 4 seconds. 30593 T00401030593 ^x In this paper, MIIS (Medical Image Information System) has been designed and implemented using INGRES RDBMS, which is based on a client/server architecture. The implemented system allows users to register and retrieve patient information, medical images and diagnostic reports. It also provides the function to display these information on workstation windows simultaneously by using the designed menu-driven graphic user interface. The medical image compression/decompression techniques are implemented and integrated into the medical image database system for the efficient data storage and the fast access through the network. 30594 T00401030594 ^x In this paper, computerized BEAM was implemented for the space domain analysis of EEG. Trans-formation from temporal summation to two-dimensional mappings is formed by 4 nearest point inter-polaton method. Methods of representation of BEAM are two. One is dot density method which classify brain electrical potential 9 levels by dot density of gray levels and the other is colour method which classify brain electrical 12 levels by red-green colours. In this BEAM, instantaneous change and average energy distribution over any arbitrary time interval of brain electrical activity could be observed and analyzed easily. In the frequency domain, the distribution of energy spectrum of a special band can easily be distinguished normality and abnormality. 30608 T00401030608 ^x Laboratory information system (LIS) is a key tool to manage laboratory data in clinical pathology. Our department has developed an information system for routine hematology using down-sized computer system. We have used an IBM 486 compatible PC with 16MB main memory, 210 MB hard disk drive, 9 RS-232C port and 24 pin dot printer. The operating system and database management system were SCO UNIX and SCO foxbase, respectively. For program development, we used Xbase language provided by SCO foxbase. The C language was used for interface purpose. To make the system use friendly, pull-down menu was used. The system connected to our hospital information system via application program interface (API), so the information related to patient and request details is automatically transmitted to our computer. Our system interfaced with fwd complete blood count analyzers(Sysmex NE-8000 and Coulter STKS) for unidirectional data tansmission from analyzer to computer. The authors suggests that this system based on down-sized computer could provide a progressive approach to total LIS based on local area network, and the implemented system could serve as a model for other hospital's LIS for routine hematology. 30609 T00401030609 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed a composite that is consisted of calcium phosphate and collagen. To use as the structural matrix of the composite, collagen was purified from human umbilical cord. The obtained collagen was treated by pepsin to remove telopeptides, and finally, the immune-free atelocollagen was produced: The cross linked atelocollagen was highly resistant to the collagenase induced collagenolysis. The cross linked collagen demonstrated an improved tensile strength. 30618 T00401030618 ^x This paper is a study on the design of adptive filter for QRS complex detection. We propose a simple adaptive algorithm to increase capability of noise cancelation in QRS complex detection with two stage adaptive filter. At the first stage, background noise is removed and at the next stage, only spectrum of QRS complex components is passed. Two adaptive filters can afford to keep track of the changes of both noise and QRS complex. Each adaptive filter consists of prediction error filter and FIR filter The impulse response of FIR filter uses coefficients of prediction error filter. The detection rates for 105 and 108 of MIT/BIH data base were 99.3% and 97.4% respectively. 30619 T00401030619 ^x To develop an artificial bone substitute that is gradually degraded and replaced by the regenerated natural bone, the authors designed and produced a composite that is consisted of calcium phosphate and collagen. Human umbilical cord origin pepsin treated type I atelocollagen was used as the structural matrix, by which sintered or non-sintered carbonate apatite was encapsulated to form an inorganic-organic composite. With cross linking atelocollagen by UV ray irradiation, the resistance to both compressive and tensile strength was increased. Collagen degradation by the collagenase induced collagenolysis was also decreased. 30620 T00401030620 ^x We have developed a monoleaflet polymer valve as an inexpensive and viable alternative, especially for short-term use in the ventricular assist device or total artificial heart. The frame and leaflet of the polymer valve were made from polyurethane, To evaluate the hemodynamic performance of the polymer valve a comparative study of flow dynamics past a polymer valve and a St. Jude Medical prosthetic valve under physiological pulsatile flow conditions in vitro was made. Comparisons between the valves were made on the transvalvular pressure drop, regurgitation volume and maximum valve opening area. The polymer valve showed smaller regurgitation volume and transvalvular pressure drop compared to the mechanical valve at higher heart rate. The results showed that the functional characteristics of the polymer valve compared favorably with those of the mechanical valve at higher heart rate. 30621 T00401030621 ^x Explosive evaporative removal process of biological tissue by absorption of a CW laser has been simulated by using gelatin and a multimode Nd:YAG laser. Because the point of maximun temperature of laser-irradiated gelatin exists below the surface due to surface cooling, evaporation at the boiling temperature is made explosively from below the surface. The important parameters of this process are the conduction loss to laser power absorption (defined as the conduction-to-laser power parameter, Nk), the convection heat transfer at the surface to conduction loss (defined as Bi), dimensionless extinction coefficient (defined as Br.), and dimensionless irradiation time (defined as Fo). Dependence of Fo on Nk and Bi has been observed by experiment, and the results have been compared with the numerical results obtained by solving a 2-dimensional conduction equation. Fo and explosion depth (from the surface to the point of maximun temperature) are increased when Nk and Bi are increased.To find out the minimum laser power for explosive evaporative removal process, steady state analysis has been also made. The limit of Nk to induce evaporative removal, which is proportional to the inverse of the laser power, has been obtained. 30622 T00401030622 ^x N1 and N2 gross neural action potentials were measured from the round window of the guinea pig cochlea at the onset of the acoustic stimuli. N1-N2 audiograms were made by means of regulating stimulant intensities in order to produce constant N1-N2 potentials as criteria for different input tone pip frequencies. The lowest threshold was measured with an input tone pip I5 dB SPL in intensity and 12 KHz in frequency when the animal was in normal physiological condition. The procedure of experimental measurements is explained in detail. This experimental approach is very useful for the investigation of the Cochlear function. Both noN1inear and active functions of the Cochlea can be monitored by N1-N2 audiograms. 30623 T00401030623 ^x In electrical impedance tomography(EIT), we use boundary current and voltage measurements toprovide the information about the cross-sectional distribution of electrical impedance or resistivity. One of the major problems in EIT has been the inaccessibility of internal voltage or current data in finding the internal impedance values. We propose a new image reconstruction method using internal current density data measured by NMR. We obtained a two-dimensional current density distribution within a phantom by processing the real and imaginary MR images from a 4.77 NMR machine. We implemented a resistivity mage reconstruction algorithm using the finite element method and sensitivity matrix. We presented computer simulation results of the mage reconstruction algorithm and furture direction of the research. 30624 T00401030624 ^x A new method of digital image analysis technique for discrimination of cancer cell was presented in this paper. The object image was the Thyroid eland cells image that was diagnosed as normal and abnormal (two types of abnormal: follicular neoplastic cell, and papillary neoplastic cell), respectively. By using the proposed region segmentation algorithm, the cells were segmented into nucleus. The 16 feature parameters were used to calculate the features of each nucleus. A9 a consequence of using dominant feature parameters method proposed in this paper, discrimination rate of 91.11% was obtained for Thyroid Gland cells. 30625 T00401030625 ^x An electrical stimulator was designed to induce locomotion for paraplegic patients caused by central nervous system injury. Optimal stimulus parameters, which can minimize muscle fatigue and can achieve effective muscle contraction were determined in slow and fast muscles in Sprague-Dawley rats. Stimulus patterns of our stimulator were designed to simulate electromyographic activity monitored during locomotion of normal subjects. Muscle types of the lower extremity were classified according to their mechanical property of contraction, which are slow muscle (msoleus m.) and fast muscle (medial gastrocneminus m., rectus femoris m., vastus lateralis m.). Optimal parameters of electrical stimulation for slow muscles were 20 Hz, 0.2 ms square pulse. For fast muscle, 40 Hz, 0.3 ms square pulse was optimal to produce repeated contraction. Higher stimulus intensity was required when synergistic muscles were stimulated simultaneously than when they were stimulated individually. Electrical stimulation for each muscle was designed to generate bipedal locomotion, so that individual muscles alternate contraction and relaxation to simulate stance and swing phases. Portable electrical stimulator with 16 channels built in microprocessor was constructed and applied to paraplegic patients due to lumbar cord injury. The electrical stimulator restored partially gait function in paraplegic patients. 30626 T00401030626 ^x Two-Dimensional modelling of the Cochlear biomechanics is presented in this paper. The Laplace partial differential equation which represents the fluid mechanics of the Cochlea has been transformed into two-dimensional electrical transmission line. The procedure of this transformation is explained in detail. The comparison between one and two dimensional models is also presented. This electrical modelling of the basilar membrane (BM) is clearly useful for the next approach to the further. Development of active elements which are essential in the producing of the sharp tuning of the BM. This paper shows that two-dimension model is qualitatively better than one-dimensional model both in amplitude and phase responses of the BM displacement. The present model is only for frequency response. However because the model is electrical, the two-dimensional transmission line model can be extended to time response without any difficult. 30627 T00401030627 ^x A method has been proposed for the fully automatic detection of left ventricular endocardial boundary in 2D short axis echocardiogram using geometric model. The procedure has the following three distinct stages. First, the initial center is estimated by the initial center estimation algorithm which is applied to decimated image. Second, the center estimation algorithm is applied to original image and then best-fit elliptic model estimation is processed. Third, best-fit boundary is detected by the cost function which is based on the best-fit elliptic model. The proposed method shows effective result without manual intervention by a human operator. 30628 T00401030628 ^x The intelligent trajectory control method that controls moving direction and average velocity for a prosthetic arm is proposed by pattern recognition and force estimations using EMG signals. Also, we propose the real time trajectory planning method which generates continuous accelleration paths using 3 stage linear filters to minimize the impact to human body induced by arm motions and to reduce the muscle fatigue. We use combination of MLP and fuzzy filter for pattern recognition to estimate the direction of a muscle and Hogan's method for the force estimation. EMG signals are acquired by using a amputation simulator and 2 dimensional joystick motion. The simulation results of proposed prosthetic arm control system using the EMf signals show that the arm is effectively followed the desired trajectory depended on estimated force and direction of muscle movements. 30638 T00401030638 ^x A new neural network architecture for the recognition of patterns from images is proposed, which is partially based on the results of physiological studies. The proposed network is composed of multi-layers and the nerve cells in each layer are connected by spatial filters which approximate receptive fields in optic nerve fields. In the proposed method, patterns recognition for complicated images is carried out using global features as well as local features such as lines and end-points. A new generating method of matched filers representing global features is proposed in this network. 30659 T00401030659 ^x An implementation scheme of the magnetic nerve stimulator using a switching mode power supply is proposed. By using a switching mode power supply rather than a conventional linear power supply for charging high voltage capacitors, the weight and size of the magnetic nerve stimulator can be considerably reduced. Maximum output voltage of the developed magnetic nerve stimulator using the switching mode power supply is 3,000 volts and switching time is about 100 msec. Experimental results or human nerve stimulations using the developed stimulator are presented. 30768 T00401030768 ^x In this paper, we describe the design methodology and specifications of the developed module-based bedside monitors for patient monitoring. The bedside monitor consists of a main unit and module cases with various parameter modules. The main unit includes a 12.1" TFT color LCD, a main CPU board, and peripherals such as a module controller, Ethernet LAN card, video card, rotate/push button controller, etc. The main unit can connect at maximum three module cases each of which can accommodate up to 7 parameter modules. They include the modules for electrocardiograph, respiration, invasive blood pressure, noninvasive blood pressure, temperature, and SpO2 with Plethysmograph.

  • 소매업은 경제, 사회, 문화, 정치를 배경으로 소비자의 요구에 부응하며 발전해 가 기 때문에 지역구조의 이해라는 측면에서 증요한 연구 주제이다. 또한 소매업은 일상생활을 영위하기 위한 기본적인 기능이므로, 이에 대한 이해는 삶의 질 향상이라는 측면에서도 중 요하다. 최근, 우리나라는 주민소득의 향상과 그에 따른 수요의 다양화, 개성화, 그리고 정보 화 사회로의 이행, 대기업 및 외국유통업의 참여, 정부의 유통산업 근대화 작업 등 소매업 환경의 변화와 함께 소매업이 크게 변화하고 있다. 따라서 미래의 변화 예측과 바람직한 발 전 방향이 제시되어야 함에도 불구하고, 이에 대한 연구가 미흡하다. 이에 광주시를 연구대 상지역으로 선정하여, 소매업의 입지와 그에 대한 주민의 이용 행태, 그리고 주민의 바람직 한 이용방안을 분석하였다. 이는 입지행태라는 순수한 학문적기여 뿐 아니라, 지역의 효율성 과 평등성의 실현이라는 응용면에서도 중요한 의의를 지닌다.

  • Introduction Recently, changes in the patterns and concepts of maternity care, in both developing and developed countries have been accelerating. An outstanding development in this field is the number of deliveries taking place in hospitals or maternity centers. In Korea, however, more than 90% of deliveries are carried out at home with the help of untrained relatives or even without helpers. It is estimated that less than 10% of deliveries are assisted by professional persons such as a physician or a midwife. Taking into account the shortage of professional person i11 rural Korea, it is difficult to expect widespread prenatal, postnatal, and delivery care by professional persons in the near future, It is unrealistic, therefore, to expect rapid development of MCH care by professional persons in rural Korea due to economic and sociological reasons. Given these conditions. it is reasonable that an educated village women could used as a "maternity aid", serving simple and technically easy roles in the MCH field, if we could give such a women incentive to do so. The midwife and physician are assigned difficult problems in the MCH field which could not be solved by the village worker. However, with the application of the village worker system, we could expect to improve maternal and child hoalth through the replacement of untrained relatives as birth attendants with educated and trained maternity aides. We hope that this system will be a way of improving MCH care, which is only one part of the general health services offered at the local health centre level. Problems of MCH in rural Korea The field of MCH is not only the weakest point in the medical field in our country hut it has also dropped behind other developing countries. Regarding the knowledge about pregnancy and delivery, a large proportion of our respondents reported having only a little knowledge, while 29% reported that they had "sufficient" knowledge. The average number of pregnancies among women residing in rural areas was 4.3 while the rate of women with 5 or more pregnancies among general women and women who terminated childbearing were 43 and 80% respectively. The rate of unwanted pregnancy among general women was 19.7%. The total rate for complications during pregnancy was 15.4%, toxemia being the major complication. The rate of pregnant women with chronic disease was 7%. Regarding the interval of pregnancy, the rates of pregnancy within 12 months and within 36 months after last delivery were 9 and 49% respectively. Induced abortion has been increasing in rural areas, being as high as 30-50% in some locations. The maternal death rate was shown 10 times higher than in developed countries (35/10,000 live births). Prenatal care Most women had no consultation with a physician during the prenatal period. Of those women who did have prenatal care, the majority (63%) received such care only 1 or 2 times throughout the entire period of pregnancy. Also, in 80% of these women the first visit Game after 4 months of gestation. Delivery conditions This field is lagging behind other public health problems in our country. Namely, more than 95% of the women deliveried their baby at home, and delivery attendance by a professional person occurred only 11% of the time. Attendance rate by laymen was 78% while those receiving no care at all was 16%. For instruments used to cut the umbilical corn, sterilized scissors were used by 19%, non-sterilized scissors by 63% and 16% used sickles. Regarding delivery sheets, the rate of use of clean sheets was only 10%, unclean sheets, vinyl and papers 72%, and without sheets, 18%. The main reason for not using a hospital as a place of delivery was that the women felt they did not need it as they had previously experience easy deliveries outside hospitals. Difficult delivery composed about 5% of the total. Child health The main food for infants (95%) was breast milk. Regarding weaning time, the rates within one year, up to one and half, two, three and more than three years were 28,43,60,81 and 91% respectively, and even after the next pregnancy still continued lactation. The vaccination of children is the only service for child health in rural Korea. As shown in the Table, the rates of all kinds of vaccination were very low and insufficient. Infant death rate was 42 per 1,000 live births. Most of the deaths were caused by preventable diseases. Death of infants within the neonatal period was 83% meaning that deaths from communicable diseases decreased remarkably after that time. Infant deaths which occurred without medical care was 52%. Methods of improvement in the MCH field 1. Through the activities of village health workers (VHW) to detect pregnant women by home visiting and. after registration. visiting once a month to observe any abnormalities in pregnant women. If they find warning signs of abnormalities. they refer them to the public health nurse or midwife. Sterilized delivery kits were distributed to the expected mother 2 weeks prior to expected date of delivery by the VHW. If a delivery was expected to be difficult, then the VHW took the mother to a physician or call a physician to help after birth, the VHW visits the mother and baby to confirm health and to recommend the baby be given proper vaccination. 2. Through the midwife or public health nurse (aid nurse) Examination of pregnant women who are referred by the VHW to confirm abnormalities and to treat them. If the midwife or aid nurse could not solve the problems, they refer the pregnant women to the OB-GY specialist. The midwife and PHN will attend in the cases of normal deliveries and they help in the birth. The PHN will conduct vaccination for all infants and children under 5, years old. 3. The Physician will help only in those cases referred to him by the PHN or VHW. However, the physician should examine all pregnant women at least three times during their pregnancy. First, the physician will identify the pregnancy and conduct general physical examination to confirm any chronic disease that might disturb the continuity of the pregnancy. Second, if the pregnant woman shows any abnormalities the physician must examine and treat. Third, at 9 or 10 months of gestation (after sitting of the baby) the physician should examine the position of the fetus and measure the pelvis to recommend institutional delivery of those who are expected to have a difficult delivery. And of course. the medical care of both the mother and the infants are responsible of the physician. Overall, large areas of the field of MCH would be served by the VHW, PHN, or midwife so the physician is needed only as a parttime worker.

  • A hypermarket as the one of the most globally standardized retailing format is also the type of store among various types of stores that the most active in expanding into other foreign markets. Recently, as several Korean retailing companies start to penetrate into Chinese market they differentiate themselves with modern facilities and customers service oriented high-end concept. China and Korea as Far East Asian countries share many common values, however precise and careful analysis should be carried out since there may also be critical differences in socio-economic aspects as well as in consumption patterns due to the level of development stages of retail industry among two countries. Even though precise and careful study is crucial on Chinese retailing market and consumers, none of researches and studies on 'how the quality of service dimensional structure is different between Korea and China', and 'what will be the most important and influential service dimensional factors for Chinese consuers compared to the hypermarkets customers in Korea' in order to improve the level of Chinese consumers satisfaction' have been fulfilled At this point of view, this study uses KD-SQS (Rho Eun Jung & Sir Yong Gu, 2008) which is a measure of Korean hypermarkets service quality to set up a hypothesis on Korean and Chinese consumers, and an empirical analysis is conducted. We try to get the answers about how the comparative importance of Service quality dimensions which decides the level of customer satisfaction is different depending on the cultural dimensions and socio-economic factors among two countries, Korea and China. Based upon the results, we try to give a valuable suggestion of what service dimensional factors should be reinforced to improve the level of CS in Chinese retailing market. Hypotheses for this study are as follows : H1. Each dimension of Service Quality significantly affects the level of CS H2. The effect of 'Basic Benefit' in service quality dimensions on the level of CS is greater in China than in Korea H3. The effect of 'Promotion' in service quality dimensions on the level of CS is greater in China than in Korea H4. The effect of 'Physical Aspects'in service quality dimensions on the level of CS is greater in Korea than in China. H5. The effect of 'Personal Interaction' in service quality dimensions on the level of CS is greater in China than in Korea H6. The effect of 'Policy' in service quality dimensions on the level of CS will be greater in Korean than in China H7. The effect of additional convenience in service quality dimensions on the level of CS will be greater in Korean than in China. More than 1,100 data were collected directly from the surveys of Chinese and Korean consumers in order to verify the hypotheses above. In Korea, stores which have floor space of over $9,000m^2$and opened later than year 2000 were selected for the samples, and thus Gayang, Wolgye, Sangbong, Eunpyeong, Suh-Suwon, Gojan stores and their customers were surveyed. In China, notable differences in the income levels and consumer behaviors between cities and regions were considered, and thus the research area was limited to the stores only in Shanghai. 6 stores which have the size of over $6,000m^2$ and opened later than 2000, such as Ruihong, Intu, Mudanjang, Sanrin, Raosimon, and Ranchao stores were selected for the survey. SPSS 12.0 and AMOS 7.0 were used as statistical tools, and exploratory factor analysis, confirmatory factor analysis, and multi-group analysis were conducted. In order to carry out a multi group analysis that decides whether the structure variables which shows the different effects of 6 service dimensions in Korean and Chinese groups is statistically valid, configural invariance, metric invariance, and structural invariance are tested in order. At the results of the tests, 3 out of 7 hypotheses were supported and other 4 hypotheses were denied. According to the study, 4 dimensions (Basic Benefit, Physical Environment, Policy, and additional convenience) were positively correlated with CS in Korea, and 3 dimensions (i.e. basic benefit, policy, additional convenience) were significant in China. However, the significance of the service-dimensions was turned out to be partially different in Korea and China. The Basic Benefit is more influential in deciding the level of CS in china than Korea, however Physical Aspect is more important factor in Korea. 'Policy dimension' did not make significant difference between two countries. In the 'additional convenience dimension', the differences in 'socio-economic factors' than in'cultural background' were considered as more important in Chinese consumers than Korean. Overall, the improvement of Service quality will be crucial factors to increase the level of CS in Chinese market same as Korean market. In addition, more emphases need to be placed on the service qualities of 'Basic Benefit' and 'additional convenience' dimensions in China. In particular, 'low price' and 'product diversity' that constitute 'Basic Benefit' are proved to be comparatively disadvantageous and weak points of Korean companies compared to global players, and thus the prompt strengthening those dimensions would be urgent for Korean retailers. Moreover, additional conveniences such as various tenants and complex service and entertaining area will be more important in China than in Korea. Besides, Applying advanced Korean Hypermaret`s customer policy to Chinese consumers will help to get higher reliability and to differentiate themselves to other competitors. However, as personal interaction, physical aspect, promotions were proved as not significant for the level of CS in China, Korean companies need to reconsider the priority order of resource allocations when they tap into Chinese market.

  • 의림지 퇴적층의 형성환경, 성인 및 형성시기를 해석하기 위하여 제천시 모산동 일대에 위치하는 의림지 일대에서 제4기 지질조사와 물리탐사를 실시하였다. 연구의 목적을 달성하기 위하여 음향측심, 호저 표층시료 및 수상시추에 의한 주상시료 채취, GPR 물리탐사, 호저 퇴적물의 입도분석, 화분분석 및 탄소연대를 측정하였다. 야외조사와 실내분석 결과, 의림지 호저 표층은 부분적으로 인위적으로 교란되거나 매립되기도 했던 흔적이 있으며, 호저의 자연구배를 따른 유수작용으로는 설명할 수 없는 굴곡부를 보이고 있다. 대부분의 호저 퇴적물은 계절적인 집중호우시에 발달하는 범람유수, 의림지 주변 교량부근 계곡과 수로들을 따라 유입되는 하천수 등에 의하여 의림지 안에 조약성 내지 부유성 입자들이 많이 유입되어 집적된 것으로 해석된다. 그리고 대부분 균질 부유물은 의림지의 중앙이나 제방이 있는 하류부에 집적되어 있다. 의림지 호저 표층에는 퇴적물의 CM 다이그램분석에서 나타나듯이 교란류나 니류작용이 발달하여 있으며 이는 의림지하부에 기반암 위에 발달하는 퇴적층으로부터 피압수가 형성되어 상승류가 작용하기 때문인 것으로 판단된다. 시추 주상치료 중에서 ER-1호공과 ER-3-1호공의 시료는 인간간섭이나 퇴적층의 교란이 적으며, 입도 분석 결과, 분급도는 불량하고, 대부분 세립질 모래와 니질물로 구성되어 있으며, 입도의 첨도와 왜도변화가 아주 다양하게 나타나고 있어, 의림지의 호저 퇴적층은 여러 번의 상이한 기작에 의한 퇴적작용이 중첩되어 형성된 퇴적층으로 해석된다. 시추주상도, 음향측심 및 GPR 물리탐사 단면과 이의 해석자료에 의하면 의림지의 퇴적층은 하류의 제방으로 갈수록 두꺼워지며, 바닥까지의 수심도 GPR 측선9에서와 같이 약 8m로 특히 깊어지는 것으로 나타났다. 한편, 의림지의 2개 시추주상시료(ER-1호공과 ER-3-1호공)에 대한 화분분석 결과, 2개의 화분대로 구분됨이 밝혀졌으며, 하부분대는 목본류 화분이 초본류보다 우점하고 있으며, 상부분대는 반대로 초본류가 목본류보가 더 우점하는 현상을 보이고 있다. 이들 화분대는 현재 습한 온대지역의 수성 혹은 수성주변 환경이 지배하는 산악이나 구릉지에서 흔히 나타나는 침엽수-낙엽활엽수의 혼합림 식생상태를 잘 대변해 주고 있는 것으로 판단된다. 끝으로, 의림지 호저 퇴적층 중에서 인위적인 교란흔적이 없는 암회색 유기질 니층에 대한 탄소연대측정 결과, 제1호공 12번 시료에서 950$\pm$40 years B.P을 얻었으며, 제3-1호공에서도 아래로 내려가면서 8, 10, 11번 시료에 대하여 500$\pm$30 years B.P, 650$\pm$30 years B.P, 800$\pm$40 years B.P의 연대측정 결과를 획득하였다. 이상과 같은 의림지 호저 퇴적층의 형성환경과 형성시기 연구를 통하여 의림지의 제방축조의 최초시기를 해석해 보면, 의림지의 제방은 적어도 과거 약 827년 전에서 866년 전에는 이미 축조되어 있었음을 알 수 있다. 과거 제천 일대에 살았던 옛사람들이 의림지 하류의 곡지중앙과 고기 충적선상지에 대한 관계용 용수조달의 필요성에 부응하여 상류부 곡지하천의 자연입지 환경을 최대한 이용하여 축조한 것으로 판단된다.

  • 연구배경 : 만성 기침은 임상에서 흔한 증상으로 대부분은 후비루증(posterior nasal dripping : PND), 천식, 위식도 역류증, 기관지염 등으로 인한 것으로 알려져 있다. 만성 기침 환자 중 일부분은 기침과 동반하여 천명이나, 호흡곤란 등과 같은 기관지 천식과 유사한 증상을 경우가 많아 기관지 과민반응 검사를 시행하게 된다. 기관지 과민반응 검사는 대부분 $FEV_1$을 측정하지만 흉곽외 기도의 과민반응은 측정하지 못하는 단점이 있다. 본 연구는 만성 기침 환자를 대상으로 기관지와 흉부외 기도의 methacholine 유발 검사를 시행하여 기도 과민 반응을 평가하여 상관 관계를 알아보고자 본 연구를 시행하였다. 대상 및 방법 : 대상 환자는 2개월 이상 기침이 있는 111명의 환자를 대상으로 하였으며, 남자 55명, 여자 56명으로 평균 연령은 $37.4{\pm}13.0$세였다. 대상 환자는 심혈관 질환, 전신 질환 등이 없었으며, 과거에 기관지 진단 받은 병력이 없고 기관지 확장제나 사용한 병력이 없었던 환자였다. 기침이나 천명 또는 간헐적인 호흡곤란 등의 증상은 문진으로 확인하였고, 기침만 존재한 환자 46명, 기침과 천명이 있는 환자 24명, 기침과 호흡곤란이 있는 환자 22명, 기침, 천명 및 호흡곤란이 있는 환자 19명이었다. 대상환자의 폐기능검사는 $FEV_1$(%) $106.5{\pm}15.3$, FVC(%) $100.1{\pm}12.8$, $FEV_1$/FVC(%) $106.3{\pm}13.1$로 정상이었다. Methacholine 유발검사는 0.0625 에서 25 mg/ml의 2배수 농도를 흡입한 5분후 기관지 과민 반응은 $PC_{20}FEV_1$으로 측정하였고, 흉곽외 기도 과민 반응은 최대 중간흡입 기류속도인 $MIF_{50}$으로 측정하여 연속 3회 감소하고 25%이상 감소한 $PC_{25}MIF_{50}$으로 측정하여 25mg/ml 이하의 농도에서 양성인 경우를 기관지(BHR) 및 흉부외 기도(EAHR) 에 각각 반응이 있다고 판독하여 대상 환자의 상관 관계를 확인하여 다음과 같은 결과를 얻었다. 결 과 : 대상 환자 총 111명중에 기관지 과민반응(BHR)이 27명, 흉곽외 기도 과민반응(EAHR)이 16명, BHR과 EAHR이 함께 있는 환자 8명으로 과민 반응이 있는 환자는 총 50명이었으며, 그외의 61명은 기관지와 흉부외 기도의 과민반응이 없었다. BHR 또는 EAHR이 양성인 환자 50명중에 기침만 있는 환자는 BHR이 3명, EAHR이 9명, BER과 EAHR이 같이 있는 환자는 2명으로 EAHR이 가장 많았으며, 기침과 천명이 있는 환자는 BHR이 10명, EAHR이 2명 및 BHR과 EAHR이 같이 있는 환자는 2명으로 BHR이 가장 많았고, 기침과 호흡곤란이 있는 환자는 BHR이 7명, EAHR이 3명, BHR과 EAHR이 같이 있는 환자는 1명으로 BHR이 가장 많았다. 기침, 천명 및 호흡곤란이 모두 있는 환자는 BHR이 7명, EAHR이 2명, BHR과 EAHR이 같이 있는 환자는 3명으로 BHR이 가장 많았다. BHR와 EAHR이 모두 음성인 환자는 총 61명이었으며, 기침만 있는 환장 32명, 기침과 천명이 있는 환자 10명, 기침과 호흡곤란이 있는 환자 11명, 기침, 천명 및 호흡곤란이 모 두 있는 환자는 7명이었다. 결 론 : Methacholine에 양성 반응인 환자중 호흡곤란이나 천명이 동반된 만성 기침환자에서는 주로 기관지 과민 반응이 나타났으며, 기침 단독 증상인 환자에서는 반응이 존재함을 알 수 있었다.

  • 서울 시내와 경기도 파주시에 소재하는 남녀 공학 고등학교의 식생활 실태 중 식사 규칙성과 식사횟수와 관련된 사항에 대하여 조사하였다. 남녀 고등학생의 식사의 규칙성에서는 남학생에 비해 여학생의 경우 상대적으로 하루 식사가 비교적 규칙적인 것으로 나타났다. 1일 동안의 식사횟수는 남녀학생 모두 대체로 '1일 3식'을 하는 것으로 나타났다. 식사섭취횟수의 형성 시기에 대한 결과에서는 남녀학생은 모두 '중학교'로 나타났으며, 특히 여학생에 있어서는 '학령기 이전'이라고 답한 경우도 28.7%로 높게 나타났다. 활동에 가장 영향을 주는 식사에 대한 답변은 남학생은 점심(41.0%)이라고 답한 결과가 가장 높은 반면 여학생은 '아침'(39.8%)이라는 결과가 높게 나타났다. 학년별 식사섭취 빈도와 규칙성의 항목에 대한 분석 결과에서는 전반적으로 규칙적인 식사를 하고 있는 것으로 나타났지만 유의차가 없었다(p<0.05). 1일 식사횟수에서는 1~3학년 모두 대체적으로 '1일 3식'을 하는 것으로 나타났다. 학년별 식사섭취횟수 형성시기에서는 모든 학년에서 '중학교'와 '학령기 전'의 순의 결과를 보여 주었다. 식사의 규칙성과 일반사항의 분석 결과, 가족 수 '5명'과 '용돈이 적을수록'의 항목에서 규칙적인 식사가 이루어지고 있었다. 용돈 중 '3만원 이하'의 경우 '5만원 이상'의 식비 지출의 경우 비교적 규칙적인 것으로 나타났다. 식사를 준비하는 사람에 따라서는 '어머니'가 식사를 준비하는 경우 상대적으로 하루 식사가 비교적 규칙적인 것으로 나타났다. 부모의 연령과 교육정도가 높고 월 가구 소득이 많을수록 하루 식사가 비교적 규칙적으로 나타났다. 부모의 직업에 따라서는 아버지 '사무직'(149명(56.9%))과 어머니 '전업주부'(279명(56.9%))인 경우 하루 식사가 비교적 규칙적인 것으로 나타났다. 1일 동안의 식사횟수와 일반사항과의 차이분석 결과에서는 대체적으로 '1일 3식'을 하는 것으로 볼 수 있었다. 한 달 용돈 '5만원 이하'의 경우 54.3%가 '1일 3식'을 하는 것으로 나타났고 식사를 준비하는 사람의 경우, '스스로' 이외에는 대체적으로 1일 3식을 하는 것으로 나타났다. 부모의 연령, 부모 학력, 월 가족소득에 따라 식사횟수와 차이를 보여주었다. 식사 섭취횟수의 형성 시기와 일반사항을 분석한 결과, '용돈'과 ' 식사를 준비하는 사람'의 결과는 '중학교'>'학령기전' 순으로 나타났다. 수면 시간과의 분석결과에서는 '5~8시간'이라고 응답한 학생들의 경우 '중학교 때 형성되었다'에서 높은 결과를 보였다. 또한 부모 연령이 낮을수록 '중학교 때 형성되었다'는 결과가 높았고 연령이 높아질수록 '학령기 전'의 결과가 높게 나타났다. 월가구소득과 식사섭취횟수와의 분석 결과에서는 소득이 높을수록 '학령기 전'이라고 답변한 결과가 높았고 소득이 낮을수록 '중학교 때 형성되었다'에서 높은 결과를 보여 주었다. 전체적으로 볼 때, '중학교 때 형성되었다'가 34.6%으로 가장 높게 나타났고, '학령 전'(23.8%), '초등학교 4~6학년 전'(13.7%), '초등학교 2학년 전'(11.8%) 순으로 나타났다. 한 끼 식사 중 자신활동에 가장 큰 영향을 미치는 식사를 분석한 결과에서는 '점심'이 37.6%으로 가장 높게 나타났고, '아침'(35.8%), '저녁'(22.8%) 순으로 나타나 전반적 '점심'이 자신의 활동에 가장 큰 영향을 미친다고 생각하는 것을 볼 수 있었다. 한 달 용돈 '9만원 이하'의 경우 '점심'이, '10~20만원'의 경우 '아침'이, '21만원 이상'의 경우 '저녁'이 가장 큰 영향을 미친다고 하여 차이를 보였다. 수면시간과의 분석 결과에서는 4, 5, 6시간의 경우 '아침'이, '7시간 이상' 수면을 하는 경우 '점심'이 가장 큰 영향을 미친다는 결과였다. 아버지의 연령은 낮을수록 어머니의 연령은 높을수록 '아침'의 영향력이 크다는 상반된 결과가 나타났다. 또한 월가구소득이 증가할수록 '아침'의 영향력을 높게 느끼고 있는 결과였다. 이상의 결과를 종합해 보면, 고등학생의 식생활태도는 성별과 학년별로 차이를 나타내어 차별화된 영양교육과 식생활 태도에 관련한 기초지식을 강화해야 함을 알 수 있었다. 식사의 규칙성과 식사횟수에 있어서는 부모의 특성과 월 가족 소득에서 차이가 나타나 고등학생 개인의 영양교육은 물론이고 가정을 연계한 영양지도에 대한 대책이 필요한 것을 확인할 수 있었다. 식사횟수의 형성은 이미 고등학생 이전에 만들어져 고정되어 있는 결과가 나타나기에 특히 다양한 교육방법을 활용하여 그 중요성을 인지하도록 만들고 올바른 식습관으로 개선된 후 유지되도록 지속적인 모니터링이 요구되었다. 아침식사보다 점심식사에 대한 영향력이 나타난 결과를 보면, 아침식사에 대한 결식과 영양불균형을 예측해 볼 수 있었고 영양 섭취가 세 끼니에 골고루 분배될 수 있는 영양지도의 중요성과 아침식사와 결식에 고등학생의 식생활태도의 후속연구를 진행해야 할 필요성을 확신할 수 있었다. 본 조사의 결과는 남녀 고등학생이 식생활태도와 영향을 미치는 요인들과 관련하여 분석해서, 실천적인 식습관 형성 및 개선에 대한 개별적이면서 세부적인 영양교육 프로그램을 구축하는데 있어 기초 자료가 활용되어지길 바란다. 또한 지속적이면서 다각적인 식사관련 후속 연구들이 진행되어 영양교육 시간이 정규 수업시간으로 정착하는 데 있어 도움이 되리라 생각된다.

  • 카멜레온은 미끈한 몸통과 화려한 색 띠들을 가진 작은 도마뱀을 말하는데 빛, 온도, 기분에 따라 색이 변화하는 것이 특징이다. 또한, 변덕스러운 사람, 요염하고 매혹적인 사람, 속물적이면서도 상황에 재빨리 대처하는 사람 등을 일컬어 카멜레온이라고 하기도 한다. 본 연구의 목적은 상황에 따라 색이 변하는 카멜레온 이미지를 요염한 변덕장이들의 섹시한 스타일로 비유해서 Wearable Art에 실루엣, 색, 텍스처 개발 기술을 접목하여 표현하고자 한 것이다. 연구방법은 카멜레온의 사실적, 개념적 특징들을 Wearable Art 작품으로 표현해 나가는 단계에서 특히, 옷감 표면에 다양한 제작 기술들을 실험해 보는 과정으로 진행되었다. 작품 이미지 컨셉은 'sensuality', 'tempting', 'splendid', 'brilliant', 'fascinating' 등으로 표현했고, 연구자의 미래지향적 기호와 움직임을 통한 편하고(comfortable) 즐거울 수 있는(enjoyable)개념 역시 포함되도록 하면서 작품 완성도를 높였다. 디자인 및 제작 포인트는 실제 카멜레온의 전체 라인, 색, 표피 질감 등 그 특징들을 분석하여 본 작품의 형태, 색, 텍스처 등을 통해 상징적으로 표현하도록 하였고, 동시에 요염한 변덕장이 카멜레온의 이미지가 암시적으로 나타날 수 있도록 하였다. 작품 실루엣은 바디컨셔스 라인(body-conscious line)이다. 이것은 카멜레온의 날씬하고 미끈한 몸체를 이미지화 한 것이며 동시에, 속세적이면서도 미래적인 이미지가 암시적으로 표현되도록 한 것이다. 카멜레온 등뼈가 드러난 것을 드레스 등이 노출되도록 하여 표현하였는데 이것은 동시에 관능적이고 요염한 카멜레온 이미지를 나타내는 것이다. 카멜레온의 유선형 머리부분 표현은 완만한 삼각형 모양의 후드패턴을 통해, 카멜레온의 길게 말린 꼬리 표현은 불규칙적인 플레어의 햄 라인으로 처리하여 상징적으로 표현하였다. 카멜레온 색들은 선명한 비비드 톤이면서 동시에 빛 또는 기분에 따라 색이 변화하는 것이 특징인데, 작품 제작 과정에서도 빛과 각도에 따라 드레스 색이 조금씩 다르게 보이는 효과를 가장 중요하게 연구하였다. 검정색 쉬폰 위에 퓨셔(fuchsia)색 작은 벨벳 물방울 무늬가 박힌 소재를 주 소재로 하여 표면에 입체적인 텍스처를 줌으로서 빛의 각도에 따라 두가지 색이 섞여져서 전체적으로 색이 다르게 보이는 착시 결과를 가져왔다. 허리에서의 빨강색과 파란색 계열의 다양한 스톤들은 실제 카멜레온 스킨 이미지와 더불어 돌출된 입체감과 그라데이션 효과로 인해 움직임에 따라 색이 다르게 보이는 결과를 가져왔다. 50% 쉬폰/50% 폴리에스테르에 벨벳 다트 무늬가 들어가 있는 원단을 사용하여 옷감 표면에 탄성실을 이용한 스모킹 주름효과를 주는 기술을 접목시켜 flexible한 스트레치성 옷감으로 재탄생시킴과 동시에 소재 표면에 오돌토돌한 텍스처가 생기게 하였다. 이것은 카멜레온의 표피와 흡사하면서 동시에 몸에 밀착되는 결과를 가져와 섹시하면서도 편안한 작품 이미지 표현에도 적절한 역할을 한다. 스톤장식은 아크릴릭카보숑(acrylic cabochons)과 잼스톤(gemstones)들을 섞어서 사용했는데 카멜레온 등 표피 질감을 상징함과 동시에 색이 다르게 보이는 효과를 나타낸다는 점에서 본 작품의 포인트이다. 드레스 제작은 주로 바이어스 결을 이용한 드레이핑 기법을 이용하였는데, 후드가 앞 몸판과 연결되어 있고 불규칙적인 사각형들이 앞에서 뒤로 옆 솔기 없이 연결되어 있다. 옷은 살아 움직이는 사람이 입어서 가장 편하고 즐거우면 옷의 완성도가 가장 높다고 할 수 있다. 카멜레온 드레스 역시 움직이는 신체와 함께 색이 다르게 보이는 기법과 효과를 연구하는 과정에서 편하고 즐거운 Wearable Art를 완성할 수 있었다. 바로 이점이 입는 예술 즉, 입고 즐길 수 있는 옷에 예술미를 가미한 Wearable Art의 진미가 아닐까 생각한다.
