This study develops a sizing system of mass-customized male suits for wheelchair users. One hundred and three male wheelchair users' 21 anthropometric dimensions were measured to identify body shapes and develop a sizing system. The measured wheelchair users' body sizes were compared with the average body sizes of Korean males from the $6^{th}$ Korean Body Size Survey to understand the body size differences between two groups. As a result of body shape classification using the KS's Drop method, wheelchair user body shapes were classified into four shapes for upper-body (A: 32%, B: 26%, BB: 24%, and Y: 18%), and two shapes for lower-body (B: 70% and A: 30%). The upper-body of wheelchair users was relatively developed than Korean males; however, the lower-body was relatively stunted. The key dimensions of a sizing system were selected as chest circumference, waist circumference, and trunk length, outside leg length based on the correlation analysis between anthropometric measures. The top sizes were determined considering chest and waist circumferences for horizontal sizes, and additionally the trunk length was divided into short, medium, and long groups for vertical sizes. The bottom sizes were selected considering the waist and hip circumferences for horizontal sizes, and additionally their outside leg length was divided into short, medium, and long groups for vertical sizes.

The purpose of this study was to examine whether any differences can be found in body comparison, body satisfaction, and appearance management behaviors according to the MBTI's typology among male and female adolescents in Gwangju and South Jeolla province, South Korea. It was conducted by a self-report survey of 534 male and female high school students in Gwangju and South Jeolla province. The collected survey data were analyzed by Means, Cronbach's ${\alpha}$, Factor analysis, and t-test using the SPSS/PC WIN 19.0 statistical program. The results were as follows: Introversion Type(I) teens tend to think a thinner body is closer to the ideal when compared to Extroversion type(E) students. They spend less time comparing their bodies with their peers. However, they usually have lower levels of body satisfaction and are more likely to be concerned about acne. Intuition Type(N) students tend to have a body figure that is a little plumper than Sensing Type(S) teens. They are inclined to try and lose weight and are concerned about acne. Sensing Type(S) students are more likely to compare their bodies with their peers than Intuition Type(N) teens. However, they are generally less satisfied with their bodies. Feeling Type(F) teens are more concerned with harmony and personal hygiene the Thinking Type(T) students. Judging Type (J) students generally want to be thinner than their current body type when compared with Perceiving Type(P) teens. When Judging Type(J) teens decide they need to be on a diet, they do their best to lose weight even if it means exercising and forgoing their favorite foods. These results indicate that it would be more effective to offer guidance to teens while taking into consideration their differences in terms of appearance management behaviors based on the MBTI Topology of Adolescents.

Recently, Wireless Body Area Network (WBAN) has promise to revolutionize human daily life. The need for multiple sensors and constant monitoring lead these systems to be energy hungry and expensive with short operating lifetimes. In this paper, we offer a review of existing work of WBAN and focus on energy-aware management in it. We emphasize that nodes computation, wireless communication, topology deployment and energy scavenging are main domains for making a long-lived WBAN. We study the popular power management technique Dynamic Voltage and Frequency Scaling (DVFS) and identify the impact of slack time in Dynamic Power Management (DPM), and finally propose an enhanced dynamic power management method to schedule scaled jobs at slack time with the goal of saving energy and keeping system reliability. Theoretical and experimental evaluations exhibit the effectiveness and efficiency of the proposed method.

As overweight and obese people have increased, obesity management programs have generated much concern in Korea. Many types of obesity management programs were operated, aimed at reducing weight, BMI, body fat percentage and so on. This study was conducted to review the features of studies in obesity management programs and systematically assess the effects which were published from 1995 to 2006 in Korea. Databases were systematically searched for published data in Korea. It were KISS (Korean studies information services system) and KERIS (Korean Education research information system), which were major literature search systems for all academic fields in Korea. Total 114 studies were initially identified, of which 21 satisfied our inclusion data. The effects of obesity management programs were assessed on the results in weight, BMI (body mass index), HDL (high density lipids), body fat percentage, self-efficacy. Effect size estimated on the equation of M1 - M2 / Sp, where M1 was mean of the experimental group, M2 was the mean of control group, and Sp was the pooled standard deviation. Magnitude of effect size was interpreted by using Cohen's definition. Cohen described small, medium, and large effect sizes as 0.2, 0.5, and 0.8 respectively. The studies about obesity management programs were the most published in 2005(26.1%). Obesity management programs were popularly operated as the type of 12 weeks intervention, exercise intervention(52.4%), quasi-experimental study(85.7%). Ten studies reported significant effects on weight, and nine studies reported significant effects on BMI and HDL. Only five and three studies reported significant effects on body fat percentage and self-efficacy respectively. The effects of each outcome were generally significant when the studies included these elements, intervention over 10 weeks, evaluation over 3 times, a comprehensive program (exercise, nutrition education, behavior modification) and reinforcing factors (self-monitoring, group discussion, one's goal setting, and etc.). Effective obesity management programs should contain these essential elements and objectives of obesity management programs must be set out evident at the beginning. The participants should be registered, educated and evaluated by continuous obesity management programs.

It is widely known that labor costs are continuously and rapidly growing in terms of the raw cost of products in Korea. The increased labor costs are degrading the competitiveness of dairy industry sector as in the other major industrial fields. Furthermore, the number of dairy farms is constantly decreasing while that of dairy cattle is increasing. Thus, mechanized and/or automated stockbreeding management systems are crucially required to support professional stockbreeding management, as well as to enhance the productivity of the sector. Hence this paper develops an IIS (Integrated Information System) for dairy cattle stockbreeding management. IIS is composed of five application modules and associated utility programs. The five modules are individual stock management, milking management, feeding management, propagation management, and disease management. The utility programs are involved in stock farm accounting, and handy unloading of individual stock data into a personal data acquisition device. Compared with existing foreign products, the developed system takes advantages of various stock body measurement data such as body weight, body temperature, milk conductivity, milking amount, and the number of walking steps. All the measured data are transmitted into a programmable logic controller that monitors and controls measurement devices. The transmitted data are finally aggregated into an integrated database located in the main personal computer. The integrated data are analyzed and reformed in the five modules of IIS, then, used for providing farmers with various farm states and information through application module scenes. Hence, IIS keeps the each module work in a systematic and compatible manner, while supervising the whole stockbreeding management system.

The purpose of this study is to classify men in their 20s by their sex role attitudes, and to study their appearance management behavior and inner characteristic variables such as socio-cultural attitudes on appearance and bodily image, which are expected to influence the appearance management behavior of each classified group. For this, a survey of 393 males in the 20s in Seoul and metropolitan areas was conducted. Factor analysis, Cronbach's alpha coefficient, and F-test were conducted on the data. First, as a result of analysis on sex role attitudes, four groups were categorized: Masculinity, Femininity, Androgyny and Undifferentiation. Second, the analysis of individual variables resulted in appearance management behavior being separated into five categories: Interests in fashion, Proper choice of clothing, Importance of bodily attractiveness, Pursuit for personality and Complementation of physical weaknesses. The socio-cultural attitude on 'appearance' was sub-categorized into Internalization, and Awareness, while 'body image' was divided into Cognitive behavioral and Affective aspects. Regarding differences in socio-cultural attitudes for appearance, body image and metro-sexual lifestyle attitudes, the androgyny group produced the highest scores. Based on these results, it can be concluded that people who take care of their physical appearance, cope effectively with social and circumstantial requirements for happiness and success, and respond flexibly and affirmatively.

Appearance management is a serious issue for adults and young people in Korean society. People of various ages have used diverse means to improve their appearances. This study focused on dieting as an appearance management behavior in female adolescents. Dieting behaviors are not just a means to improve appearance; they may also relate to individuals' beliefs and self-control. The importance of individual psychological/personality factors cannot, therefore, be ruled out. Such factors can help explain personality factors explain "what causes a compulsive diet and what factors can alleviate it". This study reviewed the literature on perfectionism and self-control as individual personality factors, and empirically examined the effects of these variables on perceived body distortion and dieting behaviors. We performed a structural equation model analysis to verify our hypothesis. The results are as follows: we found perfectionism to be positively related to perceived body distortion and dieting behaviors; we also found self-control to be negatively related to perceived body distortion though unrelated to dieting behaviors; finally, our analysis identified a relationship between perceived body distortion and dieting behaviors. These results indicate that perfectionism and self-control should be considered when conducting guidance and counseling sessions on issues related to dieting behaviors for adolescent' appearance management. This paper concludes by discussing the study's implications and limitations.

This study investigates the effects of appearance management behaviors on job search efficacy among female college students. Based on previous studies on appearance management behaviors and job search efficacy, the questionnaire items were developed. For the study, we conducted a questionnaire survey among 312 students from women's university in Seoul. The statistical analyses were performed using SPSS 23. The results were as follows. First, three types of appearance management factors have been identified: 'fashion & hair,' 'skin care & plastic surgery,' and 'body shape'; the reliability and validity of these factors were proved. Second, the appearance management behavior of female college students found to have a partially significant effect on job search efficacy: fashion & hair factor had a positive effect on job search strength; fashion & hair factor and body shape factor had a positive effect on job search skills. While skin care & plastic surgery factor had a negative effect on job search strength and job search skill. Third, between academic years, there were differences in job search efficacy but not in appearance management behavior. By majors, there were differences among skin care & plastic surgery factor, body shape factor, and job search strength factor. These results suggest that to improve the job search efficacy, proper appearance management through fashion and hair, and body shape management is necessary. In addition, it suggests that it is important to improve the effectiveness of employment by establishing the appearance management strategy that matches the characteristics of each major.

This study was conducted to investigate the effects of feeding different carbohydrate sources and garcinia cambogia extract(HCA) on body weight and lipid metabolism. Fifty 10-month-old male Sprague-Dawley rats weighting $635{\pm}6g$ were randomly divided into 5 groups and fed different experimental diets for 4 weeks. The carbohydrate(CHO) sources of each group were cornstarch(control group, 100% of CHO), fructose(F group and FH group, 25% of CHO) and sucrose(S group and SH group, 25% of CHO). FH group and SH group were fed diets containing 1%(W/W) of HCA. Food intake, body weight gain, and calorie efficiency were not significantly different among the groups. Perirenal fat pad weight of FH group was significantly lower than F group, but epididymal fat pad weight was not different among the groups. Fasting glucose level were not significant among the groups. Plasma lipid profile of FH or SH group was slightly lower than F or S group, respectively. The degree of difference of plasma lipid level was greater between F and FH group than those of between S and SH group. In liver, total lipid, triglyceride and total cholesterol level were slightly higher in F group than S group, and tended to be lower in FH group than F group, but tended to be higher in SH group than S group. Liver citrate lyase activity were not significant among the groups. These results suggest that HCA is potential material for reduction of body weight and improvement of plasma lipid profiles. But, there was no difference between fructose intake with HCA and sucrose intake with HCA in reduction of body weight and lipid metabolism.

This study was to evaluate the effectiveness of the weight control program for female college students. The program was composed of diet and behavioral modifications for 8 weeks. A total of 78 participants enrolled the weight control program. Upon completion of the program, 53 participants experienced weight loss and 25 did not. The intakes of carbohydrate and fat were significantly decreased in both groups. However, the total diet quality index-international (DQII) scores as well as individual scores such as variety scores for protein source and adequacy scores for vegetable, fiber, calcium and vitamin C and moderation scores for empty calorie food were increased significantly in weight loss group only. In the weight loss group, weight, BMI, body fat, percent body fat and waist-hip ratio were decreased significantly. In addition, compared to the weight gain group, the weight loss group had higher changes in weight (weight loss group: -2.6% vs weight gain group: 1.5%, p < 0.001), body fat (-6.0% vs 0.0%, p < 0.001), percent body fat (-3.1% vs -0.3%, p < 0.001), waist-hip ratio (-1.0% vs 0.5%, p < 0.001) and BMI (-2.6% vs 1.3%, p < 0.01). There was no difference in blood profiles between the two groups. The changes in DQI-I scores were significantly correlated with the changes in body weight (r = -0.239, p < 0.05) and BMI (r = -0.224, p < 0.05), indicating that effective nutrition education could help improve diet quality leading to successful weight management among female college students.
