  • 본 연구는 노년여성을 위한 의복 원형을 설계하기 위하여 60∼80세 의 노년여성을 대상으로 직접 계측을 실시하여 체형을 유형화하고 동작에 따른 체표면 특성을 분석하였다. 인자분석을 실시한 결과 상반신 비만요인, 높이요인, 상반신 앞면길이, 어깨 형태, 상반신 뒷면 길이, 어깨 경사도, 목형태, 진동깊이의 8개 인자가 추출되었다. 군집분석에 의한 체형분류 결과, 유형 1은 상반신의 골격이 가장 작고 왜소하며 가슴의 하수가 작은편의 앞으로 굴신된 체형이며, 유형 2는 키가 작고 보통인 체형으로 상반신의 앞뒤면 길이가 짧으며 가슴의 하수가 크고 어깨가 넓고 약간 앞으로 숙여진 체형이다. 유형 3은 키가 가장 크고 등과 어깨가 두꺼운 골격이 큰 체형이다. 유형 4는 키가 약간 크고 마른 체형에 상반신 앞면길이 인자가 큰 유형으로 약간 뒤로 젖혀진 체형이라 할 수 있다. 동작에 따른 체표면의 변화를 델마토그래프법 (Dermatograph method)에 의해 측정 한 결과, 가로 방향에서 동작에 따라 유의한 차이를 나타낸 기준선은 뒤목점-어깨끝점길이, 어깨 길이 및 앞가슴둘레선, 후액와선이며, 세로 방향에서는 어깨끝점-BP-허리중심점, 어깨중심에서 앞허리선까지의 앞길이 및 옆선길이로 나타났다.

  • 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.

  • This study investigates and analyzes the amount and shape of the front waist dart of the bodice and investigates the dart division method by bust size. Measurements at 5 arm positions were taken from 15 subjects. Clothing tests were given to 6 of the subjects. The conclusions were as follows: 1) Front Body surface changes were occurred around armpit and they were caused by the wrinkles of the armpit 2) The curved dart line was more appropriate for use with C cup, the large bust body, than the linear line. The changes of the dart amount at arm movements had different types by bust size. 3) Patterns for A & C cup body were adequate to divide the dart amount by 3 darts such as under the B.P., under the anterior armpit and side line, or to aggregate to 1 dart under the B.P. For the B cup body, however, the suitable pattern to use was the total dart amount divided by 1~2 darts and decreasing the waist line at the side line should be avoided.

  • 방사선치료에서 결손조직의 보호를 위해 사용되는 기존의 결손조직 보상체는 체표윤곽을 얻기위해 컴퓨터단층촬영영상이나 자기공명촬영영상등의 의료영상을 이용해 왔다. 하지만 이러한 촬영을 위해서는 고가의 비용이 소요되고 방사선치료에 따른 체표윤곽의 변화에 적절히 대응하지 못하는 등의 단점이 지적되고 있다. 따라서 본 연구에서는 사용이 간편한 디지털 카메라로 환자를 촬영한 후 얻은 2차원 이미지를 이용하여 결손조직 보상체를 제작하고 이의 유용성 평가를 위해 기하학적, 선량학적 평가를 수행하였다. 그 결과, 조직결손을 보정하고 정상조직을 보호할 수 있어 임상적용의 가능성을 확인 할 수 있었다.

  • Recently, according to change of lifestyle and increase of concerning in health, needs of the smart clothing based on the vital sign monitoring have increased. Along with this trend, smart clothing for ECG monitoring has been studied various way as textile electrode, clothing design and so on. Smart clothing for ECG monitoring can become a comfortable system which enables continuous vital sign monitoring in daily use. But, smart clothing for ECG monitoring has a weakness on artifact during motion. One of the motion artifact caused by shifting of the electrode position was affected skin change by motion. The aim of this study was to suggest electrode locations for clothing of ECG monitoring to reduce of motion artifacts. Therefore, change of skin surface during the movement were measured and analyzed in order to find location to minimize motion artifacts in ECG monitoring clothing by 3D motion capture. For the experiment, the subjects consisted of 5 males and 5 females in their 20' with average physique. As a result, the optimal location for ECG monitoring was deducted under the bust line and scapula which have least motion artifact. These locations were abstracted to be least affected by movement in this research.

  • 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.

  • A glove design which reflects the changes in hand surface by hand motion can reduce the undesirable effects of use of gloves on hand performance. The present study examined changes in hand length dimensions due to hand motion and identified significant factors affecting the length changes. Recruiting 120 males and females in their 20s and 30s having various hand lengths, this study measured 10 hand length dimensions, defined at 2 hand areas(phalangeal and metacarpal areas) for 5 digits, when the hand is stretched and in fist, and then calculated the percentage of length increase for each dimension. ANOVA and simple-effect analyses showed the length change percentages were mainly different depending on digit and hand area: 111-127% at the phalangeal area and 112-116% at the metacarpal area. The length change percentages of the index, middle, ring, and little fingers in the phalangeal area ascended in order and showed a high correlation(r = 0.94)with the ranges of motion of the fingers.

  • Use of a glove made of materials with a low elasticity decreases the performance of the hand such as agility, dexterity, range of motion, and grip strength. The present study examined if the adverse effects of a low-elastic glove can be reduced by a design which accommodates the changes of hand surface lengths by hand motion. Two glove designs which provide patches of elastic cloth and pleats at the finger joints and knuckle were developed by considering the hand surface length changes, and then compared with two conditions(bare hand and conventional glove design that does not consider the dynamic characteristics of the hand dimensions) in terms of completion time in peg board insertion task, maximum grip strength, discomfort in hand motion, discomfort in force exertion, and overall discomfort by 24 right-handed participants. The test results confirmed that wearing of a glove significantly reduced the agility and grip strength capability of the hand and indicated that the novel designs were effective to lessen the performance decreases compared to the conventional design. Also, of the glove designs, the pleat glove design was found most preferred for both better hand performance and less subjective discomfort.
