This study utilized data to classify and characterize the body types of plus-size adult men aged in their 30s and 40s. Diversity is an important factor in the era of inclusive design, and discussion about size diversity to include the plus size should be accommodated. Data from 493 adult men classified as obese (with a World Health Organization criterion ≥25 BMI) were used for the analysis. The results of the study are as follows. Six independent factors were extracted using factor analysis for cluster analysis, which were then classified into five types. Type 1 (29.01%) was identified as body type I with the smallest degree of obesity. Type 2 (15.4%) was identified as body type Y with wide shoulders and a thin waist. Type 3 (14.2%) was the largest body volume (body type O), while the fourth (19.27%) identified as body type H has a large height and upper body. Lastly, type 5 (22.11%) has a long lower body and a slim abdomen, referred to as body type X. This study presents a basis for the development of various clothing sizes utilizing the body shape characteristics of plus-size men in their 30s and 40s. Follow-up research is needed to develop patterns for plus size men and to design various products.
The purpose of this study was to analyze the breast growth variation trends and characteristics of Korean adolescent girls based on 3D body measurements. Subjects were 174 girls aged between 13 and 18. 3D body scanning data were collected and the data were measured by Geomagic Design X program. The total of 18 anthropometric measurements and 4 index items were analyzed. The main results of this study are as follows: 1) Overall, the breast growth of adolescent girls got out of children's body shapes at the age of 14 and the adult's body shapes appeared remarkably at the age of 18. Before the age of 15, the adolescent girls' breast enlarged. 2) The surface lengths of upper body, which means the breast volume, showed significant growth above B cup groups rather than under A cup groups. The demand of B cup size (32.2%) was higher than A cup size (25.9%). And 35.6% of subjects' brassiere band size was 70. 3) The thorax grew evenly in the circumference, depth and breadth. The thoracic development related to the breast volume as well as the whole upper body's development. These results reveal that it is necessary to develop adolescent girls' brassiere reflecting on adolescent girls' breast growth variation trends and characteristics by age, breast size and thoracic development.
에너지 위기의식이 급격히 고조되고 지속 가능한 친환경 에너지원이 이슈화되면서 휴대용 전자기기 산업의 발전은 전원을 공급하기 위한 새로운 에너지원을 요구하고 있으며, 이러한 점에서 언제 어디서나 전력 수확을 가능하게 하는 인체 전력에너지 수확 시스템의 연구가 요청된다. 인체 에너지를 수확하는 방식의 하나인 열전은 인체와 주위 환경간의 온도차이로부터 에너지를 수확하는 방식으로, 본 연구에서는 열전수확에 적합한 의복의 구조와 소재를 탐색하여 인체 전력에너지 수확의류를 위한 기초적 지침을 마련하고자 하였다. 이를 위해 의복의 폐쇄부 구조에 따른 환경 온도와 의복내 온도 간의 차이를 분석하고, 의복의 소재에 따른 환경 온도와 의복내 온도 간의 차이를 도출하였다. 분석 결과, 의복구조에 따른 의복내 온도에 있어서는 인체 부위에 따른 차별화된 결과를 얻을 수 있었는데, 가슴과 등 부위에서는 '폐쇄부 유'의 의복구조인 경우가 '폐쇄부 무' 의복구조에 비하여 의복내 온도가 더 높은 것으로 나타났고, 팔 부위에서 다리 부위로 갈수록 '폐쇄부 유'와 '폐쇄부 무'의 의복구조에 따른 의복내 온도의 차이가 줄어들었다. 한편, 의복소재에 따른 환경 온도와 의복내 온도 간의 차이를 분석한 결과, 두 소재 중 하나의 소재가 일관성 있게 더 높은 온도를 보이지는 않았으며, 인체 부위별로 차이를 보였다. 이러한 의복구조와 소재에 따른 환경 온도와 의복내 온도 간의 차이 결과를 토대로, 인체 전력에너지 수확의류를 위한 지침을 도출하였다.
In this study, the representative hand shapes for the adult Koreans were analyzed by factor analysis and cluster analyses. The analyses were conducted on the anthropometric data of 58 hand dimensions from 325 subjects having nonhomogeneous demographics. Maximum hand circumference, first phalanx length of index finger, and ratio between the two measures were the independent variables for the cluster analyses. The results of the study showed that Korean hand shapes can be divided into 2 clusters irrespective of their size for each of the male and female group. There were slight differences in component ratio of hand shapes with respect to the occupation and the age, but their differences were not statistically significant. The representative Korean hand shapes and their anthrpometric dimensions could be used to design and establish proper sizing system for various hand operating devices.
인체측정 시, sheet를 이용한 계측치 기록에 의한 직접측정 방법은 계측치 입력시간이 오래 걸리고, 입력과정에서 착오가 생길 수 있다. 따라서 본 연구는 계측치 입력과정에서 발생할 수 있는 착오를 감소시키고, 계측 소요시간을 단축시키기 위해 샅높이 항목과 큰․작은․둥근 수평자 항목에서의 인체측정 실시간 입력 프로그램을 개발하였다. 본 시스템은 인체측정과 동시에 입력 화면에 계측치가 실시간으로 입력되고, 모든 항목의 측정을 마치면 자동으로 각 피험자명으로 저장된 Excel파일과 Access DB가 생성된다. 남녀피험자 50명을 대상으로 새롭게 개발한 인체측정 실시간 입력 프로그램을 사용하여 계측을 실시한 결과 sheet를 이용하는 기존 Martin식 계측법과 비교하여 샅높이 항목과 큰․작은 수평자를 사용하는 항목에서 유의한 시간 절감 효과를 확인할 수 있었다.
The paper proposes a stiffness measurement device composed of a measurement part including six indenters and a fixing part including four fixtures. The device is able to make simultaneously measurements of the stiffness of human arm. The six indenters make use of both position and force control schemes sequentially whenever needed. In addition, the loadcells and the digital encoders are attached to the indenters and electric motors, respectively, so that the data can be provided in real time. On the end of the indenter, two-axis potentiometer is attached in order to measure the angle difference between the applied force axis and the axis normal to the skin of human arm, and to convert the force measured on the loadcell into the actual applied force to skin. For this purpose, the mapping between the voltage output and the angle of potentiometer was obtained by fitting it for each axis. Ultimately, the measurement device was able to measure the stiffnesses of six regions of human arm.
