  • 착의행동을 일으키는 전단계의 감각으로서 국소의 냉감각과 체표 각 부위에 있어서의 냉점분포에 대하여 측정을 하였다. 피험자는, 냉점분포 측정에 한국인 여자 대학생 30명, 냉감각측정에는 한국인과 일본인 여자 대학생 8명을 대상으로 하였으며, 환경조건은 실온 $29^{\circ}C{\pm}1^{\circ}C$, 상대습도 $55{\pm}5\%$의 인공기후실로 하였다. 냉자격으로서는 $0^{\circ}C$의 냉각이 사용되었으며, 측정부위는 냉점분포 측정의 경우 체표 20부위, 냉감각 측정의 경우 체표 13부위로 하였고 측정결과는 다음과 같다. (1) 체표면의 냉점분포 밀도는 부위에 따라서 다르며, 체간부와 두부는 냉점분포 밀도가 높고 말단부에 갈수록 그 분포가 낮아졌다. 특히 가장 민감한 부위는 복부였다. 즉 체간부와 두부는 중핵온을 일정하게 보지하므로서 중핵부 체내온의 변화를 방어하기 위한 온도 수용 부위로서의 역할을 하고 있으며, 말초부는 냉점분포가 낮아서 기온에 따라 체표온(외각온)을 광범위하게 변화시키는 사지부의 온도정보입력의 역할을 담당하고 있다고 하겠다. (2) 각 부위에 있어서의 냉감각 순위는 일본인과 한국인 피험자간에 고도의 상관(r=0.93)이 보여져, 양 피험자군간에 차이는 볼 수 없었다. 3) 냉점분포 밀도가 높은 부위인 복부는 냉감각도 가장 민감하였으며, 냉점분포 밀도가 낮은 하퇴부는 냉감각 감수성도 낮게 나타났다. (4) 발바닥과 손바닥은 냉감각을 민감하게 느끼는 부위임에도 불구하고 냉점분포 밀도가 낮게 나타났으며, 이는 특수성이 있는 부위로서 주목되어지는 결과라고 하겠다.

  • The purpose of this study is to seek the change of body surface according to cycling motions and to give suggestions to the pattern and spare space between body and wear in each bodily parts to be heavily considered for making the bicycle wear. The cycling motions were analyzed by taking the sequential pictures of cycling covering motion by a digital camera. The experiments with gypsum were toward a woman in her twenties. We draw the line standard of the body's surface, separated their gypsum-replicated fragments of body's surface following the analyses of the change in their lengths. As the motions were made, we decided the degree of the changed length as spare space when compared the erected posture with the cycling posture, presenting the pattern of the cycling wear with the preparation of wears for testing. After that, the essential experiments were conducted toward three cycle players wore our experimental wears. Regards their evaluated appearance, evaluations over three points were obtained from all parameters except the width of front armhole. Accordingly, our experimental wears were remarkably understood as a relatively proper wear as bicycle wear.

  • In this paper, the discharge phenomena and electromagnetic waves caused by discharge with insertion of a solid insulator and flame between sphere-sphere electrodes in air ware investigated. The surface discharge light and patterns of flame generated on a solid insulator surface were observed by using a CCD(Charged Coupled Device) camera. Also, the radiated electromagnetic waves were measured by using a biconical antenna and a spectrum analyzer. The surface discharge light generated on the solid insulator surface was larger and the size of flame was smaller by increasing allied voltages. Also, voltage distortion by voltage drop was strongly revealed when a insulator surface was polluted. When a solid insulator surface was not polluted, the electric field stength of electromagnetic waves was 10∼17[dBuV/m] higher than a polluted solide insulator, and 5∼9[dBuV/m] higher than a polluted solide insulator and flame.

  • Respiration sating radiotherapy technique developed In consideration of the movement of body surface and Internal organs during respiration, is categorized into the method of analyzing the respiratory volume for data processing and that of keeping track of fiducial landmark or dermatologic markers based on radiography. However, since these methods require high-priced equipments for treatment and are used for the specific radiotherapy. Therefore, we should develop new essential method whilst ruling out the possible problems. This study alms to obtain body surface motion by using the couch based computer-controlled motion phantom (CBMP) and US sensor, and to develop respiration gating techniques that can adjust patients' beds by using opposite values of the data obtained. The CBMP made to measure body surface motion is composed of a BS II microprocessor, sensor, host computer and stopping motor etc. And the program to control and operate It was developed. After the CBMP was adjusted by entering random movement data, and the phantom movements were acquired using the sensors, the two data were compared and analyzed. And then, after the movements by respiration were acquired by using a rabbit, the real-time respiration gating techniques were drawn by operating the phantom with the opposite values of the data. The result of analysing the acquisition-correction delay time for the data value shows that the data value coincided within 1% and that the acquistition-correction delay time was obtained real-time $(2.34{\times}10^{-4}sec)$. And the movement was the maximum movement was 6 mm In Z direction, In which the respiratory cycle was 2.9 seconds. This study successfully confirms the clinical application possibility of respiration gating techniques by using a CBWP and sensor.

  • This study is based on a representative body shape drawn from previous studies that classify adult male torso shapes. In this study, a design method is proposed by developing a tight-fit pattern that can be easily developed into various items and designs using the body surface development figure. This is obtained by converting the 3D body shape of the model representing the representative body shape. The specific design method was conducted as follows. Actual measurement values were used for waist back length, waist-to-hip length, shoulder length. The scye depth was determined as C/4-1.7 cm, and the front and back Interscye was set at (1/2 × actual measurements)-0.2 cm. The front-back neck breadth was set to (1/5 × base neck circumference)-1.3 cm and (1/5 × base neck circumference) cm. The front-back neck depth was set to (1/5 × base neck circumference)-1.2 cm and 3.5 cm. Front chest circumference was C/4-1 (front-back difference)cm; (1/4 × back chest circumference) was C/4 + 1 (front-back difference) + 0.3 (dart amount) cm. Front waist circumference was W/4-0.2 (front-back difference) + 2.2 (dart amount) cm; back waist circumference was W/4 + 0.2 (front-back difference) + 2.5 (dartamount) cm; front hip circumference was H/4 + 0.2 (ease) + 0.2 (front-back difference) cm; and back hip circumference was H/4 + 0.2 (ease)-0.2 (front-back difference) cm; Front droop was 1.6 cm. The newly developed tight-fit pattern is expected to be of great use as a basis for garment construction.

  • In radiotherapy, accurate patient positioning and set up are important factor that treatment can influence success. In generally, the 3-laser system is used when the patient set up. But today the body surface scanning system(C-Rad system) is trying to use. Compare and evaluate the C-Rad system and the 3-laser system to check availability. Head and neck that are no movement of internal organs and easy to apply fixation device are limited. Alderson Rando anthropomorphic phantom and 10 patients who have lesions of head and neck are targeted. C-RAD system's setup error mean and standard deviation are the X axis($0.55{\pm}0.51mm$), Y axis($-0.2mm{\pm}0.523mm$), Z axis($-0.85{\pm}0.587mm$) in the phantom study, and in the patient study X axis($-0.05{\pm}0.621mm$), Y axis($0.075{\pm}0.755mm$) Z axis($-1.025{\pm}0.617mm$). So C-RAD system is better than 3-laser system mostly, but C-RAD system's error rate is a little worse than 3-laser system in the Z axis. When radiation treatment of head and neck, body surface contour scanning system contribute to correct positioning and minimize the set up error.

  • Thermography is a diagnostic procedures that measures infrared energy emitted by the skin. Thermography detects body temperature change which are controlled by the autonomic nervous system. It does show the thermal dysfunction that correlates closely with pain syndromes as well as normalization when the healing process takes place. Experienced clinical interpretation of the thermal pattern is necessary to diagnose and establish causation. Thermography is useful in the diagnosis of painful conditions such as herniated disc diseases, myofascial syndrome, myositis, musculoligamentous injury, reflex sympathetic dystrophy, athretic injuries, vascular diseases, arthritis, inflammation and breast tumors.
