  • When a body with slant angle after its shoulder is moving at high speed, the turbulent motion around the afterbody is generally associated with the flaw separation and determines the normal component of the drag. By changing the slant angle of afterbody, there exists a critical angle at which the drag coefficients change drastically. Understanding and control of the turbulent separated flows are of significant importance for the design of optimal configuration of the moving bodies. In the present paper, a new Large Eddy Simulation technique has been developed to investigate turbulent vortical motions around the afterbodies with slant angle. By basis of understanding the structure of turbulent flaw around the body, the new configuration of afterbodies are designed to reduce the drag of body and the nonlinear effects due to the interaction between the body configuration and the turbulent separated flows are investigated by use of the developed LES technique.

  • This study is about saliva from a GIGONG's point of view, it's importance, and it's funtion that recently medical world proved. And here is GIGONG training with saliva. The results were summarized as follows. 1. It is detected that saliva have function to prevent symptoms of senility and have effect of an $anti{\sim}cancer$ medically in recent years. So it is said that science proved narrowly that so called a predecessor speak of salive interms of high praise and they already experienced. 2. Similar substance to saliva exist in human body besides nature food, but human body have materials that deal with all situation to occur from every kind of environment and disease. And exactly saliva is an example of it. 3. We cannot turn back sweat, blood, tears and sperm again that is out of human body once, but we can swallow again only saliva. Therefore, we must experience training that swallow saliva to make us healthy by ourselves, and we don't have to commit a foolish act to cough up saliva at random that a predecessor speak of in terms of high praise, and to be second to JUNG(精). 4. Saliva is a kind of antibody or hormone, so I think that we need to make a study of using saliva with a GUIGONG that is an example of way to strengthen immunity of human body.

  • This study examined the importance of screening for changing bodybuilding and fitness category. The screening criteria for bodybuilding, the background and reason for the creation of new bodybuilding and fitness items, the screening criteria for new items, and the use of drugs were described. The current bodybuilding gives high marks to excessive muscles and excessive diet conditions, and new bodybuilding category have been newly established in line with the recent global trend of pursuing natural beauty over abnormally excessive muscles, and the screening criteria also prioritize the balance of ideal and overall muscles to fit your height and weight. In addition, fitness events such as physique and bikini are gaining popularity with the establishment because they focus on not excessive muscles and natural elements of the body that ordinary people can challenge. Since athletes as well as ordinary people are using drugs to increase muscles and suffer side effects, IFBB(International Federation of BodyBuilding) and KBBF(Korea Body Building Federation) should consider and improve the current bodybuilding screening standards that avoid excessive muscles, and it is believed that bodybuilding and fitness events will develop only when strict punishment and continuous anti-doping education are carried out.

  • Among current health-related issues, obesity is considered one of the foremost, and the importance of this subject has fostered a national interest in body weight loss. In this study, the differences in recognition of body weight loss according to age and gender are investigated. The subjects of the study were 720 (male: 360 and female: 360) aged between 10-60 years, who had experienced to try body weight loss during 6 months prior to this study. Anthropometrics, general characteristics, personal reasons for body weight loss, comprehension of body weight loss, and a knowledge of diet-related issues were assessed through a questionnaire. The anthropometric measurements showed significant differences in height, body weight (present and desired) and BMI (p < 0.05) by age and gender. The difference between desired body weight and actual body weight was greater for younger subjects or female, regardless of whether they had under- or normal body weight (p < 0.05). Reasons for body weight loss varied; younger subjects and female tended to lose body weight "to enhance their appearances", whereas the older subjects and male desired "to improve their health" (p < 0.05). Subjects had different concepts concerning body weight loss; younger subjects and female considered body weight loss as "maintenance of a slender figure, or becoming more lean". On the other hand, older subjects and male thought body weight loss to be "effects approaching normal body weight" (p < 0.05). From our studies, it can be concluded that attitude on concerning body weight loss varied according to a age and gender. Thus, consideration of this individual differences would be vital in developing contents of a particular nutritional education program for body weight loss.

  • This study investigated body-related values, body-esteem, and the relationship between them based on the survey data drawn from female college students in three East Asian countries(Korea, Japan, and China). 168 Korean, 108 Chinese, and 152 Japanese female college students responded to questions designed to measure four sorts of body values (operability, inclination, locus of evaluation, and social utility) and four dimensions of body esteem (appearance, weight, health, overall). The results showed that body-related values and body-esteem differ among three countries. Japanese showed the highest acceptance level for the voluntary body alteration(operability), while chinese scored the lowest. Inclination to body appearance over health was higher in Korean than in Japanese and in Chinese. Korean also evaluated the importance of body appearance and its social utility the highest, followed by Japanese and Chinese. There were dramatic differences in body esteem between Korean and Japanese. Regarding body-esteem, Korean showed the highest appearance-esteem, but the health-esteem was the lowest. On the contrary, Japanese showed the highest health-esteem, but the appearance-esteem was lowest. Chinese showed the highest weight-esteem. Four sorts of body values showed significant correlations with appearance-esteem and weight-esteem, respectively but not with health-esteem. Overall, the result supported the prediction that different political, social, and economic backdrops in three countries would be related with different body-related values and body esteem in the female college students.

  • Objectives To examine the relationship between health-related quality of life (HRQoL) and body mass index (BMI) of obese children. Methods This cross-sectional study included 387 children. HRQoL was measured with the PedsQLTM 4.0 Generic Core Scale. BMI was classified according to the World Health Organization Asia-Pacific obesity guidelines. Psychosocial factors (body image, self-esteem, and depression/anxiety) were also measured. Data were analyzed using one-way analysis of variance, Pearson's correlation and Path analysis. Results Obese participants reported lower score for physical evaluation, self-esteem, appearance evaluation component of body image, total HRQoL score, and physical/emotional/social function components of HRQoL ; they reported higher score for depression/anxiety. In addition, results indicated that as BMI increased, appearance evaluation, total HRQoL score, and social function component of HRQoL dropped. Path analysis revealed that BMI did not directly affect HRQoL ; however, BMI directly affects body image and self-esteem, indirectly mediates depression/anxiety, and thereby impacts on an individual's HRQoL. Conclusions Body image and self-esteem, rather than BMI itself, have more influence on HRQoL. This reinforces the importance of therapeutic intervention to enhance body image and self-esteem among obese children.

  • Importance of appearance as a means of self-expression and communication is increasing in modern society even for men. And appearance has become an significant factor affecting men's quality of life. The main objectives of this study were to develop an instrument measuring appearance related quality of life(ARQoL), and examine the body factors influencing ARQoL. The ARQoL instrument was developed from in-depth interviews, focus group interviews, and literature review, and were revised through two pre-tests. The final questionnaire was administered through on-line survey with 440 men. Quota sampling was used based on age and body size. The results indicated that high ARQoL group showed significantly higher satisfaction on body factors including face, weight, shape, body proportion, hair, and overall impression than low ARQoL group. There was no significant difference in terms of satisfaction on height between two groups. Factor analysis showed that ARQoL consists of four factors - physical, economic, psychological and social factors. Overall impression was the most important body factor affecting all four factors of ARQoL and has very strong influence especially on economic ARQoL. BMI was also a significant factor affecting physical, economic and social ARQoL except psychological factor of ARQoL. Face had significant influence only on economic and psychological aspects of ARQoL.

  • The purpose of this study was to investigate meal behavior and food preferences of children with different body types. This survey was conducted using a questionnaire for 274 boys and 257 girls in the 6th grade of elementary school in Anyang city. A questionnaire method was used. Food preferences of 14 food groups were tested with 5 likert scale points. Body types were divided with weight-length index(WLI) calculated by height and weight. The cut-off point for the underweight children was 90, and that of the overweight children was 100. The mean weight of the underweight children(26.2%) was 31.9$\pm$4.0kg, and that of the overweight children(26.9%) was 49.4$\pm$6.3kg. The average BMI of overweight children and underweight children was 21.0kg/$m^2$ and 15.5kg/$m^2$respectively. Perceived health status was different based on body types, and more of the overweight children answered they are healthy compared to the underweight children, Body types were not significantly different based on parent's education and occupation. Only 56.7% of the children ate breakfast at a regular time, 60% and 42.9% of the children had their lunch and dinner at regular time, respectively. Higher percentage of overweight children had irregular breakfast(20.1%) and skipped their breakfast and dinner compared to the other groups, however only dinner was statistically significant. The most frequently answered reasons for skipping meals were 'no time to eat'(50%) and 'bad side-dishes'(17.0%). Food preference was not different among the body type groups, however rice-cake was preferred in the underweight group, as well as milk and lettuce were preferred in overweight group. The preferences for milk and grain powdered drink(misitgaru) were same as or a carbonated soft drink. Focusing pubericant, it is necessary to have a regular breakfast. With regard to the importance of nutrition and health for children, the nutrition education for meal behavior and food preference to achieve a balanced diet should be considered.

  • Objectives: The purpose of this study was to find out the relation factors of weight control behaviors, mental health status and body image perception in adolescents and to use basis data of health promotion for adolescents. Methods: This study used data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V-2, 2011). The subjects were 653 between 12-19 age. Data analysis was done with SPSS/WIN 19.0 using Chi-square test, and Logistic regression. Results: The result is as follows. The case of female adolescents, abnormal perception of body image was significantly higher on weight reduction effort and normal weight, low weight in BMI. The case of male adolescents, abnormal perception of body image was higher on normal weight in BMI. Conclusions: The adolescents tend to do unreasoning weight loss behavior without properly perception for their body image. Therefore, we suggest that adolescents be provided social support for positive body image and be developed perception program with the importance of inner values.
