Purpose. This study was to investigate the relationship between hand function and characteristics of hand. Methods. Participants were 56 occupational therapy students who studied in M colleges in Gyengsangnam-do, april 20, 2015 from 1 May, and hand circumference and length (vertical, w), the width was measured. A hand grip on the measurement subject was measured by the Grip dynamometer and Pinch gauge. Results. The results was hand length, width, circumference long, broad, thick, and hand strength was a greater correlation emerged. Grip strength was showed a significant correlation to the size and grip strength was also correlated. Conclusion. This study was correlation of length of the hand, a length wide and strength of the finger circumference.

The hand performs functions such as grabbing and other movements. In order to accomplish these movements in various kinds of operational environments, appropriate gloves must be worn to protect your hands. Choosing the appropriate type of glove is very important when wearing gloves in these types of operational environments. The reasons one wears gloves varies depending on age and gender. Unmarried women in their early twenties, for example, occasionally wear gloves for decoration rather than for functional reasons. However, previous studies examined a range of topics, and as such investigations dealing with specific body shape and demands of consumer are needed. Therefore in this study, the hands of unmarried women ranging in age from 20 to 24 were measured and hand shape types were analyzed in order to present basal data which can be used to help design improved glove patterns and produce appropriate, functional gloves. A total of 261 Korean women were measured. Fifty-seven right hand dimensions were measured and five dimensions from both hands were measured. Six factors were identified through factor analysis and those factors constituted $73.259\%$ of total variance. Two clusters of hand shapes were categorized using 6 factor scores by cluster analysis. Type 1 hand shape is defined as long hands with small width, girth, and thickness, long and thin fingers, and high vertical palm height. Type 2 hand shape is defined as short hands with large width, girth and thickness, short fingers, thick knuckles, and short vertical palm height. The characteristics of type 1 and 2 hand shapes are similar to women's hand type classification results from previous reports, but there was a significant difference in subject distribution by type. Therefore, standard data on hand shapes should be produced by developing measuring instruments and selling more accurate standard measuring points. By doing this it could help in the development of improved glove patterns, and also aid in planning production based on hand type.

HCI 분야에서 대표적인 손 제스처 인식은 IT기기의 개발과 더불어 사용자와 기기 간의 상호작용 및 정보교환을 위한 방법으로 주목받고 있다. 영상 처리를 통한 손 제스처 인식에서 손바닥 영역 검출은 처리속도 및 인식률 향상에 기여하는 핵심 처리 과정이다. 본 논문에서는 손바닥 영역 검출(palm area detection)을 위해 손과 손목을 영상 분할(image segmentation) 하는 새로운 방법을 제안한다. 손의 해부학적 특성으로 가장 넓은 폭이 발생하는 엄지와 소지의 장골 간격을 손 영상의 수평 투사 히스토그램으로 계산 후 이 간격을 지름으로 하는 원을 그려 손바닥 영역을 검출한다. 이 방법의 우수성을 검증하기 위하여 다단 형판정합(multiple stage template matching)을 사용해 10가지 손 제스처에 대해 기존 방법 4가지와 인식 성능을 비교 평가한다. 손 제스처 인식에 관련한 연구가 다양하나 손바닥 영역 검출에 특화된 성능 비교 문헌이 저조함을 강조한다.

We present an augmented reality (AR) application for cell phone where users put a virtual pet on their palms and play/interact with the pet by moving their hands and fingers naturally. The application is fundamentally based on hand/palm pose recognition and finger motion estimation, which is the main concern in this paper. We propose a fast and efficient hand/palm pose recognition method which uses natural features (e.g. direction, width, contour shape of hand region) extracted from a hand image with prior knowledge for hand shape or geometry (e.g. its approximated shape when a palm is open, length ratio between palm width and pal height). We also propose a natural interaction method which recognizes natural motion of fingers such as opening/closing palm based on fingertip tracking. Based on the proposed methods, we developed and tested the AR application on an ultra-mobile PC (UMPC).

Purpose: The purpose of this study was to investigate the most effective exercise position of Latissimus dorsi's activities during Pull up, Push up and Lat pull down among few positions of hand grips(pronation, Supination and neutral grip) and grip widths(30cm, 60cm) based on EMG activities. Method: 10 healthy adults were participated in this study and the surface EMG activities of the Latissimus dorsi were measured during Pull up, Push up and Lat pull down exercise according to specific hand grip and grip width positions. The maximum and mean value of Latissimus dorsi's EMG activities at all positions were recorded and analysed by ONE-WAY REAPTED ANOVA. Results: The showed that the most Latissimus dorsi's activities is during Pull up exercise. Main results are as follows 1)maximum value: For Pull up, among all studied positions, Rt Latissumus dorsi, position of Supinated grip and 60cm grip width showed strongest muscle activation based on maximum EMG value. Statistical significance was assumed at p<.05. 2)mean value: For Pull up, among all studied positions, Both Latissimus dorsi, position of pronated grip and 60cm grip width showed strongest muscle activation based on mean EMG value. Statistical significance was assumed at p<.05. Conclusion: Therefore, taking the results of this study, Pull up exercise would be the best exercise of Latissimus dorsi's activation. It is recommended to do in pronated grip position and 60cm grip width during Pull up to make body fit.

야외에서 효율적인 지렁이 채집방법을 개발하기 위해 몇 가지 채집방법들의 채집효율을 비교하였다. 공시된 채집방법들은 1) 단위면적(50 cm${\times}$50 cm)의 토양속 30 cm 깊이까지 파헤쳐 수작업(Hand Sorting)하는 방법, 2) 단위면적의 토양표면에 겨자, 포르말린, 후추 등의 기피제 용액을 부어주는 방법, 3) 단위면적 토양속 10-15 cm까지 수작업 후 기피제를 부어주는 혼합처리방법(수작업+기피제)이었다. 수작업방법이 기피제 용액을 사용하는 경우보다 더 많은 개체수를 채집할 수 있었으나 강도높은 노동력과 많은 노동시간을 요구하였다. 기피제를 토양표면에 적용하는 방법에서는 겨자와 포르말린의 효율이 유사하였고, 후추는 양자에 비해 현저하게 채집효율이 떨어졌다. 수작업 및 겨자 혼합처리가 수작업 및 포르말린이나 수작업 및 후추 혼합처리보다 채집효율이 높았으며, 전적으로 수작업에 의존하는 채집방법과 유사한 개체수를 채집할 수 있으면서, 노동시간이나 노동강도는 현저하게 줄일 수 있었다. 따라서 충분한 양의 겨자용액을 만들 수 있는 물이 공급될 수 있는 야외에서는 지렁이를 채집할 때는 '수작업 및 겨자처리'의 혼합처리방법이 효과적으로 이용될 수 있으며 이때 수작업을 적용하는 토양깊이는 15 cm 정도가 적정할 것으로 생각된다.

The purpose of this study is to measure the change in evacuation time at high schools according to the change in hallway width using an evacuation simulation program and to analyze the result of such change. In order to measure the evacuation time according to the change in the hallway width according to the 「Rules on the Standards for Evacuation and Fire Protection Structures of Buildings」 and to analyze the change in evacuation time resulted from the increase in the number of occupants, a scenario was constructed by applying the 「performance-oriented design method and standard for firefighting facilities, etc.」. As a result of the experiment, it was found that the evacuation time was the shortest when the width of the hallway was the widest, which was 3m. On the other hand, the evacuation time took the longest at 1.8m, which was the width of the second narrowest hallway. For the safety of high school students who spend a lot of time at school, it is necessary to secure a wide hallway width when building a new school or to provide periodic safety education in the case of an existing school whose hallways are considered narrow.

The purpose of this study was to determine the fundamental foot measurement data that is essential for a shoes size system of women in their 20~30s according to a survey of Korean hand-made shoes companies. This research on the current situation of shoes companies was done by interviewing and surveying employees of these companies. The subjects for this study were 407 women in their 20s~30s who lived in a metropolitan area, and who wanted to enhance their foot health and prevent injury with a proper shoes size system. They were measured with the 3D scan method in use of 6th Size Korea. The result of this study showed that there is considerable dissatisfaction related to women's shoes and the current foot size system using foot length. The Korean hand-made shoes companies assessed here did not use the KS system, but they recognized the necessity of measuring the foot width and circumference, understanding that doing so properly can decrease the return and repair rate. And current target age for shoes bye the hand-made shoes companies was reported to be approximately 5 years. There were significant results according to ANOVA, factor and cluster analyses according to the age range pertaining to the foot length, circumference and height. Each element was significantly correlated with user's satisfaction. There were 5 factors and 3 clusters represented, and foot circumstance and width were as important as foot length with a range of 5 years.
