This study analyzed differences between three-dimensional (3D) body scanning and manual measurements, aiming to assess whether 3D scanning can replace traditional anthropometric tools, such as tape measures and calipers. Data from 4,478 participants in the 8th Size Korea Project were analyzed, covering 43 measurement items. Since Given that the 3D and manual measurements were performed on the same subjects in the 8th Size Korea Project, it was possible to determine the correlation more accurately between the two measurement methods more accurately. Using Applying ISO 20685-1(2018) standards, 15 out of the 43 items fell within allowable error limits. When classified into six types, "small circumferences" and "segment lengths" showed averages of 3.35 mm and 3.10 mm, respectively, within acceptable range. "Body heights" and "body depths" slightly exceeded the limit, with averages of 5.28 mm and 6.58 mm. "Body widths" and "large circumferences" surpassed the limit, with means of 16.77 mm and 16.18 mm. The study offers an objective basis to for validate validating 3D measurements' measurements' reliability and accuracy, addressing various industries' needs for information on the human body's dimensions information.

The purpose of this study was to analyze the measurement data of 13 ~ 18 year old male students and to characterize the body shape of the lower body, Through this, I tried to provide basic data for the production of pants for adolescent men's students. As a result of analyzing the body shape factor of the lower half, two factors were classified. 'Vertical factor' of the lower body composed of the circumference, thickness, and width, and the 'horizontal factor' of the lower body composed of the length and height. The body shape of the lower half was classified into four categories according to the circumference and length of the lower half of the male students, such as 'short bird legs', 'long crane legs', 'short pillar' and 'long pillar'. In the study of Hong Eun-hee (2005), body type was classified according to horizontal factor and vertical factor like this study. By age, boys aged 13 to 14 can see that the lower body is thin and short, the lower body is thin and long body is 15-16 years old, and the lower body is relatively thick and long body is 17-18 years old. As the age increases, the growth in the vertical direction occurs first and the growth in the horizontal direction occurs. It is thought that it is necessary to set a different amount of allowance for setting the length and the circumference according to the age of the youth. When the age is young, the amount of allowance in the circumferential direction should be increased, and the amount of allowance in the longitudinal direction after 15 years of age should be increased more than other age groups.

BACKGROUND/OBJECTIVES: Relocation to new environments can have a negative impact on health by altering body weight and dietary patterns. This study attempted to elucidate changes in body weight, food security, and their current food and nutrient consumption in adult North Korean refugees (NKR) living in South Korea (SK). SUBJECTS/METHODS: This study analyzed data on 149 adult NKR from a North Korean refugee health in SK cohort at four time points (leaving North Korea, entering SK, first examination, and second examination). Body weight was self-reported at the two earlier time points and directly measured at the two later time points. Food security, diet-related behaviors (dietary habits and food consumption), and sociodemographic information were obtained using a self-administered questionnaire. Nutrient intake information was obtained by one-day 24-hour recall. Statistical analyses were performed with SPSS ver 23.0. RESULTS: Body weight increased during relocation by an average of 4 kg, although diversified patterns were observed during the settlement period in SK. Approximately 39.6% of subjects maintained their body weight between the first and second examinations, whereas 38.6% gained and 22.1% lost at least 3% of their body weight at the first examination by the second examination. Food security status improved from 12.1% food secure proportion to 61.7%. NKR showed generally good food and nutrient consumption (index of nutrient quality: 0.77-1.93). The body weight loss group showed the most irregular meal consumption pattern (P < 0.05), and eating-out was infrequent in all three groups. Consumption frequencies of food groups did not differ by group, except in the fish group (P = 0.036). CONCLUSION: This study observed considerable body weight adjustment during the settlement period in SK after initial weight gain, whereas food security consistently improved. More detailed understanding of this process is needed to assist healthy settlement for NKR in SK.

광학적 방식에 의한 비침습적으로 신체 전체의 비만도를 측정하기 위해서는 단일 특정 부위에서 측정하는 것은 오차가 너무 크기 때문에 여러 부위에서 측정하고 이를 통계적 방법에 의해서 정확도를 높일 수 있다. 이를 위해서 백색광 LED광원을 이용하고 전기적 방식인 BIA(Bio-electrical Impedance)방식으로 동시에 측정하여 광전기적 지방측정에 관한 상관식을 유도하였다.

Selfie practices on social media can result in negative body image for men. The current study investigated the dual body image pathway model for the relationship between selfie practices on social media and body satisfaction, with internalization as a mediator. Structural equation modeling analyses supported our research model when studying 446 young Korean male Instagram users. The results indicated that selfie editing behavior, but not selfie browsing behavior, significantly predicted an increased internalization of a body ideal. The positive associations between internalization, muscularity dissatisfaction, and body fat dissatisfaction were confirmed. Additionally, the indirect effects of selfie editing behavior on muscularity and body fat dissatisfaction due to internalization were significant. The study confirmed the detrimental effects of selfie behavior on body satisfaction for male social media users. The results provided valuable information that selfie editing may be a risky behavior since it can result in developing muscularity and body fat dissatisfaction. Theoretical contributions and practical implications were discussed. Future research should address the age and cultural differences that may elucidate the impacts of selfie practices on men's body image concerns.

Obesity is a worldwide epidemic problem. The downward trend of an obesity onset age calls for research efforts on how to develop useful nutrition educational programs for children to maintain adequate body weight. Understanding the roles of objective and subjective body status in obesity-related attitudes, knowledge, and behaviors can provide important information. The current study aimed to examine obesity-related attitudes and knowledge and practices of eating behavior guidelines in relation to obesity and body shape satisfaction among children. The gender effect in the relations was also investigated. A self-administered survey was conducted with 260 fifth grade children at 2 public elementary schools in the suburbs of Seoul. Information on demographics, body size, body satisfaction, obesity-related attitudes and knowledge, and eating behaviors was collected. Study findings from one-way analysis of variance tests indicated no differences in mean scores of the attitudes, knowledge, and eating behaviors across the levels of obesity for both gender. The levels of body shape satisfaction was, however, found to be significantly related with the attitudes and eating behaviors in girls, while no such relation was seen in boys. Girls with lower body shape dissatisfaction had significantly more negative attitudes toward obesity which was not translated into practice of healthy eating behaviors. That is, contrary to general expectation, the level of practicing the eating behavior guidelines was significantly lower in those girls. While underlying reasons for this observation is not fully answered, gender-specific, body satisfaction-stratified, and behavior-focused approach in designing obesity prevention programs for elementary school girls is suggested efficient and useful.

최근 COVID-19 팬데믹으로 인해 전 세계적으로 사람의 왕래가 많은 장소에서 발열 검사는 선택이 아닌 필수가 되었다. 특히 K-방역으로 세계를 선도하고 있는 우리나라에서도 방역기기의 일환으로 건물 출입시 감염 예방을 위해 출입자를 대상으로 체온계 혹 은 열화상 카메라를 통해 발열 검사를 하고 있다. 하지만 현재의 프로세스는 체열 검사와 출입 명부 작성이 이원화 되어있기 때문에 출입을 통제하는 인력이 배치되어야만 하고, 출입자가 직접 체열을 검사하고 개인정보를 기록하여야 하는 상황이라 신뢰성도 낮고 개인정보 유출의 위험도 높은 상황이다. 따라서 본 논문에서는 비대면 스마트 인증 발열 감지기에 대해 고찰하고 이원화된 체열 측정과 출입 기록에 대한 프로세스를 단일화 하기 위한 스마트 인증 프로세스를 제시한다.
