In the taste of patients suffering from arthritis, while the group of patients falling that ill at first and the recurring group didn't smoke cigarets, during alcohol and coffee on the whole, and the group of patients falling once again that ill drank a cup of distilled linquor and three cup of coffee or more on the whole per one day, and the group of patients falling that ill at first liked sort of vegetables and the recurring group liked very much sons of vegetables and fresh and meat in their loving food normal times. 10. Analysing the distribution on the dining table used by patients and the structure of a powder room, at first, in the structure of a powder room, the group of patients filling that ill have a toilet stool using as their sits, and a Bush toilet on the whole, and the recurring group, a toilet stool using as their sits and conventional type, and in the structure of a dinning table, the group of patients falling that ill at first and the recurring group turned high, each as 66.9% and 6.3%, who have a dining table carring here and there. 11. In the distribution of patients of arthritis in relation to stress, the case that they feeled severly symptoms of arthritis when thay got stress, turned high, each, as 78.6% in the recurring poop, and the case not knowing, as 61.5% in the first group. In the extent of stress normal times, the case that they got much stress on the whole turned high, each, as 72.4% in e recurring group, and the care that got less stress on the whole, as 60.0%. 12. In the distribution on the distinction of symptoms and impedimental extent, the recurring group turned high in each variable. Analysing the feature of the recurring group, in the distinction of symptoms, the case that they fooled much that the node of an articulation is stiff, turned high, as 71.6, and in the distinction of treatment before. patients came to helpk, the theraphy of Chinese medicine (physical theraphy), as 84.4%, the theraphy of Chinese medicine (acupuncture, moxacautery, Chinese medicine), as 73.2%, and in the distinction of the satisfing extent on treatment, the case of comman, as 72.3%, and in the cause of arthritis, the case not recruiting their health after a birth, as 68.5%, and the case not recovering wholely an articulation having got hurt, as 62.8%, and in the state of physical exercise before they begined suffering from arthritis, the case exercising very much on the whole, (as 74.2%), and in the extent of subjective impediment, the case of not being able to act almost, as 66.7%, the case of acting but feeling some hard, as 66.3%. 13. The correlation in variables in relation to arthritis Analysing realted variables, the recurring frequency showed correlation with such as the extent that patients got stress normal times, and the exercising state before suffering arthritis, and showed contra-correlation with academic careers, the wights, coffee. The cigaret, e loving food of taste, showed corralation with the weight, stature, alcohole as the loving food of taste. On the basis of this result medical members of heal, who are related to the regular education, public education or development of this program, should be concerned to prevent orthris.

Among quadruples or higher multiplicity stars, only a few binary systems have been discovered. They are important targets to understand the formation and evolution of multiple stellar systems because we can obtain accurate stellar parameters from photometric and spectroscopic studies. We present the observational results of this kind of rare object 1SWASP J093010.78+533859.5, for which the doubly eclipsing feature had been detected previously from the SuperWASP photometric archive. Individual PSF photometry for two objects with a separation of about 1.9 arcsec was performed for the first time in this study. Our time-series photometric data show that the brighter object A is an Algol-type detached eclipsing binary with an orbital period of 1.3 days and the fainter B is a W UMa-type contact eclipsing binary with a period of 0.23 days. Using the high-resolution optical spectra, we obtained well-defined radial velocity variations of the system A. Furthermore, stationary spectral lines were detected and should have originated from the other stellar component, which was confirmed by the third object contribution from the light curve analysis. No spectral feature of the system B was detected, probably due to its faintness. We obtained the binary parameters and the absolute dimensions from each light curve synthesis. The primary and secondary components of the system A have a spectral type of K1 and K5 main sequences, respectively. Two components of system B have nearly the same type of K3 main sequence. Light variations at out of eclipses were appeared in both systems, interpreting as the effect of stellar spots on these late spectral type stars. We estimated the distances to the systems A and B individually. They may have similar distances of about 70 pc and seem to be gravitationally bound with a separation of about 130 AU. In conclusion, we suggest that 1SWASP J093010.78+533859.5 is a quintuple stellar system with a hierarchical structure of a triple system A(ab)c and a binary system B(ab).

환경수 중 크립토스포리디움 및 지아디아 분석방법은 현재 어떤 방법도 만족할만한 민감도, 특이도, 재현성을 인정 받지 못하고 있어, 다양한 형태의 정도관리 및 수행도 평가가 요구되고 있다. 본 연구는 1623방법(USEPA :Method 1623)을 사용해 한강 지표수에 대한 크립토스포리디움 및 지아디아 접종시험과 현장시료 동시분석시험에 기초하여, 환경수 중 이들의 존재여부와 농도를 측정함에 있어 분석결과의 정확도 및 신뢰도, 그리고 회수율에 미치는 영향요인을 검토하였다. 1623방법에 의한 결과, 평균적으로 한강 지표수시료에 존재하는 크립토스포 리디움의 46%와 지아디아의 60%를 검출할 수 있는 것으로 나타났으나, 각각의 회수율 범위가 13-73% 및 28-84%로 변이가 매우 커서 실제 환경 중 두 원생동물의 농도를 결정하기 위해서는 반복측정 및 통계학적 인 접 근이 수반되어 야 할 것으로 나타났다. 또한 IMS (immunomagnetic separation)중 산첨가에 의한 해체·분리과정을 1 회 더 반복함으로써 지표수시료에서의 총회수율의 약 10%를 향상시킬 수 있었으며, flow cytometry로 계수·준비된 (오)시스트((oo)cysts)를 정도관리에 사용할 경우 보다 신뢰할만한 결과를 얻을 수 있었다. 형광항체 및 DAPI염색은 현장시료특성 이나 전 처리과정에 따라 동일하지 않은 형광특징을 보인 바, 접종 된 현장시료 정제액에 대한 염색결과도 참조되어야 하며, 환경시료에는 다양한 비특이물질이 함유되어 있어 DAPI (4',6-diamidino-2-phenylindole) 염색 및 DIC(Differential Interference Contrast)에 의한 내부구조 관찰이 최종 동정기준이 되어야할 것으로 나타났다.

현재 위치인식에 관한 많은 기술들이 존재한다. 하지만 서로 다른 곳에 위치한 신호수신장치들이 먼 곳에 위치한 특정 물체의 위치를 정확하게 알아내기 위해서는 해당 물체 또는 사용자의 단말장치에서 내보내는 신호의 정확한 시간을 알아야 한다. 이러한 목적 때문에 ToA 기술보다는 TDoA 기술이 보다 적합하다. TDoA 기술을 기본으로 하는 전자 감시 시스템 및 다른 위치추적 장치들은 이격 장치들간의 정밀한 시각동기가 되지 않아서 신호수신장치들에 의해 보내지는 신호로부터 정확한 TDoA 값을 획득하는 것이 불가능하다. 이렇게 직접적으로 정확한 값을 받지 못함으로써 위치 추정 에러가 발생된다. 이러한 이유로 이격 장치들간의 정밀한 시각동기 기술은 TDoA를 기반으로 하는 위치인식에 있어서 필수적인 것이다. 본 논문에서는 TDoA를 기반으로 하는 위치인식을 위해, 제안된 정밀한 시각동기 기술의 정확성과 측정오차가 평가된다. TDoA를 기반으로 하는 위치 측정 오차는 제안하는 시각동기 알고리즘을 사용할 때 크게 향상된다.

본 논문에서는 부모학대의 주이유가 무엇보다도 가족내 역동과 정신병리에 있다고 생각되어, 부모학대를 주소로 입원한 청소년들을 대상으로 임상적인 소견과 병력을 심도 있게 알아보고, 그 저변에 있는 정신병리와 가족역동, 특히 모자관계를 중심으로 알아보았다. 국립서울정신병원내의 1987년부터 1997년까지 입원한 환자중 부모에게 신체 공격 또는 신체적 위해를 가하겠다는 언어적, 비언어적인 위협을 가한 환자중 정신증, 기질적인 뇌질환, 자폐아, 정신지체아동을 제외한 21명 환자의 면담과 병록지 검토를 통하여 대상 청소년들에 대한 고찰을 하였다. 부모학대로 입원한 21명의 환자중 남자 14명, 여자 7명으로 진단은 품행장애, 경계선 인격장애가 가장 많았으며, 평균 연령은 10대 중반이었다. 가족역동과 발달병리상 4개의 소집단으로 나눌 수 있었다. 1) 어머니와의 공생적인 관계군；(1) 어머니와 공생적인 관계에서 분리되지 않은 상태로 청소년 시기를 맞이하였고, 아버지의 정서적. 실제적 부재상태에서 어머니의 가정내 유일한 남자인 환자에 대한 과도한 밀착이 두드러졌다. 제2차 분리개별화시기인 청소년을 맞이하여 어머니와의 갈등적 관계에서 오는 내적 긴장감과 분노를 표현함과 동시에 나름대로 분리를 획득하고자하는 시도로서 어머니를 향한 신체적 공격을 이해할 수 있겠다. (2) 이 환자들은 탄생 이후부터 중한 질환과 발육부진으로 부모의 과잉보호로 공생적 관계에 머물며 유아적인 전지전능감, 힘에 대한 환상의 비현실적인 감각을 제대로 처리하지 못하고 현실적응을 못하고 부모에게 과도하게 의존하고, 자신의 요구가 충족되지 않으면 쉽게 과격행동으로 표출하였다. 2) 경계선 인격장애군：이들은 양육상의 적절한 모성의 결핍과 부모자체의 성격상의 문제와 미숙함으로 의존성이 조장되고 분리가 방해받아 발달상 재접근시기에 머물고 있었다. 제2차 분리개별화시기인 청소년기를 맞이하여 의존과 독립에 관한 그들의 위기 갈등이 되살아나고, 이 갈등의 표현으로 부모학대가 일어났다. 3) 품행장애군：이들은 부모와 기본적인 애착관계를 형성하지 못하였고, 부모의 존재는 이들에게 단지 자신의 필요 충족의 대상이었다. 환자 자신의 전지전능한 요구가 충족되지 못하고 갈등 상황에 빠졌을 때 공격성과 충동 조절 능력의 결여 상태에서 부모를 향한 폭력을 행사하게 된 것으로 이해된다.

In the traditional buffeting response analysis method, the spanwise incomplete correlation of buffeting forces is always assumed to be same as that of the incident wind turbulence and the action of the signature turbulence is ignored. In this paper, three typical bridge decks usually adopted in the real bridge engineering, a single flat box deck, a central slotted box deck and a two-separated paralleled box deck, were employed as the investigated objects. The wind induced pressure on these bridge decks were measured via a series of wind tunnel pressure tests of the sectional models. The influences of the wind speed in the tests, the angle of attack, the turbulence intensity and the characteristic distance were taken into account and discussed. The spanwise root coherence of buffeting forces was also compared with that of the incidence turbulence. The signature turbulence effect on the spanwise root coherence function was decomposed and explained by a new empirical method with a double-variable model. Finally, the formula of a sum of rational fractions that accounted for the signature turbulence effect was proposed in order to fit the results of the spanwise root coherence function. The results show that, the spanwise root coherence of the drag force agrees with that of incidence turbulence in some range of the reduced frequency but disagree in the mostly reduced frequency. The spanwise root coherence of the lift force and the torsional moment is much larger than that of the incidence turbulence. The influences of the wind speed and the angle of attack are slight, and they can be ignored in the wind tunnel test. The spanwise coherence function often involves several narrow peaks due to the signature turbulence effect in the high reduced frequency zone. The spanwise coherence function is related to the spanwise separation distance and the spanwise integral length scales, and the signature turbulence effect is related to the deck-width-related reduced frequency.

본 논문은 DP(dynamic programming) 매칭법을 확장하여 흘림체 한글을 온라인으로 인식하는 방법에 대하여 논한 것이다. 한글의 자소는 보다 간단한 자소에 선분이 점차로 추가되어 보다 복잡한 구조로 발전되는 특징이 있다. 자소의 조합에 의해 구성되는 한글에는 유사한 문자 패턴이 많다. 이러한 특성으로 인하여 한글에 대하여 DP매칭법을 적용하여도, 입력문자와 표준문자와의 패턴간 거리를 정확하게 구하는 것이 곤란하다. 본 방식에서는 DP매칭을 행하기 전에, 한글의 최초, 최후선분의 특성을 살린 대분류매칭을 행함으로써 DP매칭의 대상수를 줄였다. 본 방식은 DP매칭법에 자소패턴의 추출기능을 부가함으로써, DP매칭을 확장하여, 한글의 문자패턴간의 거리를 정확하게 측정하는 것을 시도한다. 자소패턴의 추출은, 자소패턴을 구성하는 선분의 ON/OFF, 방향코오드, 방향코오드의 변화, 배치 구조등을 조사함으로써 행한다. 이와같이 하므로써 필기운동 변화의 흡수와 비교적 안정된 스트로크의 분리가 가능함을 확인하였다.

Background: Unstable surface-based core training can significantly enhance core strength, but no studies have compared the effects of balance pad- and sling-assisted exercises. Objects: To study the effects of unstable surface-based balance pad- and sling-assisted core strength exercises on muscle activity. Methods: Twenty male students aged 20-25 years participated in this study. The effects of three types of core strength exercises, performed with a sling or balance pad, on the activities of three muscles, i.e., the right musculus obliquus externus abdominis (EO), right erector spinae (ES), and right gluteus maximus (GM), were examined. Results: 1) In the glute bridge exercise, the percentage of maximum voluntary contraction of the EO, ES, and GM were significantly different between the balance pad- and sling-assisted exercises. The relative contribution of the ES and GM activities to all muscle activity were not significantly different between the two training types, whereas that for EO showed a significant difference. 2) There was no significant difference in the percentage value of maximum voluntary contraction (%MVC) among the EO, ES, and GM during the "leg-lifting with flat support" exercise, and there were no significant difference in the relative contributions between the two training types. 3) In the "side bridge leg separation exercise", the %MVC of the ES, EO, and GM were significantly different between the two training types. Conclusion: Sling training for core muscles was generally better than balance pad assist training. The majority of physiotherapy patients require core training. Our results could guide physiotherapists in the choice of targeted exercises for these patients.

Background: In general, measurement qualities of cross-culturally adapted quality of life (QOL) measures are altered in many aspects, although versions of them are well-validated measures. The latent trait and measurement qualities of the QOL measures for cancer-related samples should be considered when developing cross-culturally adapted measures. Objects: To investigate the latent trait of the translated into Korean World Health Organization Quality of Life-BREF (WHOQOL-BREF) administered to different cancer survivors who had palliative rehabilitation care service (PRCS). Methods: A cross-sectional study with 139 cancer survivors who had an experience of cancer survivorship with PRCS were conducted with a two-step analytic procedure including exploratory factor analysis (EFA) to confirm the latent trait and Rasch rating scale modeling to investigate the measurement qualities of the cross-culturally adapted WHOQOL-BREF measure. Results: While the original WHOQOL-BREF measure constitutes a 4-latent trait, the EFA reveals that 24 items constitute six substantial factors. The item loadings are predominantly spread over factors 1 through 4 in a mixed manner of the latent traits, while the loadings of 'physical health' and 'environmental health' latent traits show similarity to what the original measure intended to assess. The latent trait of the cross-culturally adapted WHOQOL-BREF measure administered to different cancer survivors is likely to reveal more dimensions than the original WHOQOL-BREF measure. Person reliability (i.e., analogous to Cronbach's alpha) and separation are measured with 0.92 and 3.48, respectively. All items except the one item (medical treatment item) fit the Rasch rating model. Conclusion: Findings suggest that the latent trait and the measurement qualities of the cross-culturally adapted WHOQOL-BREF measure should be taken into consideration when applying versions of it to various populations.

This study attempts to establish a system extracting and monitoring cultural grounds of seaweeds (lavers, brown seaweeds and seaweed fulvescens) and abalone on the basis of both KOMPSAT-2 and Terrasar-X data. The study areas are located in the northwest and southwest coast of South Korea, famous for coastal cultural grounds. The northwest site is in a high tidal range area (on the average, 6.1 m in Asan Bay) and has laver cultural grounds for the most. An semi-automatic detection system of laver facilities is described and assessed for spaceborne optic images. On the other hand, the southwest cost is most famous for seaweeds. Aquaculture facilities, which cover extensive portions of this area, can be subdivided into three major groups: brown seaweeds, capsosiphon fulvescens and abalone farms. The study is based on interpretation of optic and SAR satellite data and a detailed image analysis procedure is described here. On May 25 and June 2, 2008 the TerraSAR-X radar satellite took some images of the area. SAR data are unique for mapping those farms. In case of abalone farms, the backscatters from surrounding dykes allows for recognition and separation of abalone ponds from all other water-covered surfaces. But identification of seaweeds such as laver, brown seaweeds and seaweed fulvescens depends on the dampening effect due to the presence of the facilities and is a complex task because objects that resemble seaweeds frequently occur, particularly in low wind or tidal conditions. Lastly, fusion of SAR and optic spatial images is tested to enhance the detection of aquaculture facilities by using the panchromatic image with spatial resolution 1 meter and the corresponding multi-spectral, with spatial resolution 4 meters and 4 spectrum bands, from KOMPSAT-2. The mapping accuracy achieved for farms will be estimated and discussed after field verification of preliminary results.
