The early stage of 3D anthropometry data has been used to obtain qualitative rather than quantitative information. However recent 3D body scanners as a common research tool for anthropormatric measurments have made it possible to obtain body surface data of sufficient resolution and accuracy. The purpose of this study is finally to develop motorcycle jacket for enhanced comfort and fit, to test the accuracy and reliability of 3D measurments of motorcycle riding posture, and to analyze the change in 20's adult male's body surface measurements between the standard anthropometric position and motorcycle riding posture. The results of this study were as follows: There were no significant differences between the study and Size Korea measurments in total traditional measuring items and most of measuring items, such as length, circumference antropometric items and interscye items though not waist back length and upper arm circumference. A comparison of 3D body surface measurments in the two different measuring postures, the bodysurface measurments such as waist front length, biacromion length, front interscye, arm length, underarm length in the motorcycle riding posture decreased than that in basic posture, whereas waist back length, back interscye, C.T.W length increased. The body surface measurments such as chest, bust, upper circumference in the motorcycle riding posture decreased than that in basic posture, whereas neck, waist, hip, elbow circumference increased.

본 논문에서는 손동작 인식을 위한 새로운 방법을 제안한다. 손 추출을 위한 방법으로는 피부색과 boundary energy 정보를 이용하고 moment method로 손바닥의 중심을 구하게 된다. 손동작 인식은 두 단계로 나눌 수 있다. 첫 번째 단계는 손 형상 인식으로 병렬 신경망을 이용하였다. 손 형상의 패턴을 추출하기 위해서 fitting ellipses method를 이용하였다. fitting ellipses method는 추출된 손 영역을 12개의 타원형으로 분류하고 타원 외곽선의 흰 픽셀 비율을 계산한다. 패턴은 12개의 입력 노드로 신경망에 입력되고 4개의 출력 노드로 출력되는데 각 출력 노드는 0~1사이의 값을 갖게 된다. 손 형상은 4개의 출력 노드의 구성으로 나타낼 수 있다. 두 번째 단계는 손동작 추적과 인식이다. 손동작 추적과 인식을 위해서는 손동작의 위치 정보를 예측 할 수 있는 Kalman Filter를 이용하였다. 실험은 Windows XP상에서 수행되었고 제안한 알고리즘의 효율성을 평가하였다. 손 형상을 인식하기 위해서 300개의 이미지를 인식기에 훈련시키고 200개의 이미지를 실험에 사용하였다. 194개 이상의 이미지가 정확하게 인식 되었다. 그리고 손동작 추적 인식을 실험하기 위해서 1200번의 손동작(각 동작은 400번)을 사용하였고 그 중 1002번의 손동작이 정확하게 인식 되었다.이러한 결과는 제안된 방법이 손 영역을 추출하고 손 동작을 인식하는데 유용함을 확인 할 수 있었다.

In this study, we attempted to make an original pattern of clothing for an abnormal type of figure, especially for the type of kyphosis. We measured the curvature of the spine of a woman with kyphosis with a Martin measuring instrument and a silhouetter in the following ways. First, we counted the rate of shrinkage of the standard lines drawn on the surface of the body according as the body moved. Secondly, placing the front and back darts, the front and back shoulder darts and the side darts according to“Munhwa”pattern, we made cubic cuttings of four moving postures as well as the standing one. Thirdly, we superposed the developed patterns of the standing and the moving postures, measuring the position change and the amount to the change of the darts, and compared them. The results are as follows: 1) In the developed pattern of a cubic cutting of the basic pattern and the standing posture, the neckhole became larger than that of the basic pattern, and the waist line was lowered than that of the basic pattern because the center back line was shortened due to the curved backbone.

This study was to design the clean room garment which fits for a body and adjusts well to the action. We examined the body's changes in action through a body measurment and made a sample of the clean room garment to which had adapted the body's changes in action and evaluated the function and the appearance compared with the existing the clean room garment. The followings were summery of the results : 1. Back intersyce breadth decreased, trunk length increased and the other parts were not change. At a posture of raising hands($M_3$) in comparison with an upright posture($M_0$). Back intersyce breadth, hip length and knee length increased and the other parts were a little change. At a bowing posture($M_2$) in comparison with an upright posture($M_0$). Back hip girth, knee length, hip length and leg length increased and the other parts were not change. At a working posture on a chair($M_1$) in comparison with an upright posture($M_0$). 2. The overall clean room garment was made increasing on the changes of part of a body through measuring and body measurement. 3. From the test of the function, it became known that the devised clean room garment was superior to the existing one in the parts of neck, shoulder, armpit and elbow at a working posture on a chair($M_1$), in the parts of neck, shoulder, and armpit at a bowing posture($M_2$), and the armpit at a posture of raising hands($M_3$). The appearance was better on the whole. 4. From the examination of photographs, the waist line of the devised clean room garment was not so much pulled up as that of the existing one on moving. And when sitting down on a chair, the waist line of the existing one was pulled down while that of the devised one had no change. As above, we investigated the actual conditions of wearing the clean room garment and measured the body's changes according the various actions. So we applied these results to the devised clean room garment but we couldn't research the clean mom effect of it owing to not obtaining the measuring instrument. The aspect of ergonomics liked the feeling of wearing and fitted to the action must be given consideration to the clean room garment, and simultaneously the dust-resistant effect must be taken into consideration in order to improve the quality of the goods. Therefore, we think it should be continued the research on the dust-resistant effect, material, washing method, quality control, and size along with the aspect of ergonomics.

Background: This study aimed to determine the effects of training on breathing re-education on pain and dysfunction levels, posture, quality of life (QoL), and pulmonary function in patients. Methods: This study included 34 patients with chronic neck pain and upper thoracic breathing pattern were included. The participants were assigned to either the routine physical therapy program (RPTP) (CG; n=17) or RPTP and breathing pattern re-education training (EG; n=17). The CG and EG groups performed RPTP for 40 minutes, and only the EG groups performed breathing re-education training for 10 minutes. Exercises were performed thrice weekly for both groups. Level of pain and dysfunction, posture, QoL and pulmonary function status were assessed before and after the intervention. Results: After four weeks of intervention, numeric pain rating scale (NPRS), Korean version of neck disability index, cranio-vertebral angle, cranial rotation angle, and 12-item short form health survey-physical and mental component summaries had significant differences before and after intervention in both groups (p<.01). However, only NPRS, forced vital capacity, forced expiratory volume in 1s, and maximum voluntary ventilation showed significant interactions between the two groups and measurement time (p<.01). Conclusion: Breathing re-education training and RPTP may be optimal for patients with chronic neck pain and may be more effective in improving neck pain and pulmonary function.

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.

This paper presents a novel knitted data glove system for pattern classification of hand posture. Several experiments were conducted to confirm the performance of the knitted data glove. To find better sensor materials, the knitted data glove was fabricated with stainless-steel yarn and silver-plated yarn as representative conductive yarns, respectively. The result showed that the signal of the knitted data glove made of silver-plated yarn was more stable than that of stainless-steel yarn according as the measurement distance becomes longer. Also, the pattern classification was conducted for the performance verification of the data glove knitted using the silver-plated yarn. The average classification reached at 100% except for the pointing finger posture, and the overall classification accuracy of the knitted data glove was 98.3%. With these results, we expect that the knitted data glove is applied to various robot fields including the human-machine interface.
