Purpose: To provide the epidemiological information for developing preventive programs encourage appropriate eating and weight control behaviors. Method: 349 college students in Seoul were administered self-report question- naires to examine eating habits, trend of disordered eating, weight reduction practice and body size evaluation from September to October 2002. Data were analyzed by SAS program for frequency, t-test, ANOVA with Scheff test. Result: The mean eating score was moderate and it differed by subjects' characteristics. The mean score of EAT-26 was relatively lowered, and 3.4% of the subjects score showed disordered eating behavior. It differed significantly by subjects' general characteristics. 30.4% of total sample were currently trying to lose weight and had interested in trying to lose weight. EAT-26 was significantly different by weight reduction practices and interest. Perceived body size differed by the score of eating habit and EAT-26. Conclusion: It can be suggested weight preoccupation have a relation to eating habits, weight control practice and disordered eating. Further study is recommended educational interventions targeting at-risk subjects.

Objective : This study was done to clarify ambiguous non-standard weight and measuring units in medical classics. Methods : Using medical classics and research dissertations, we studied the basic definitions of weight and measuring units and the types of non-standard weight and measuring units. We compared non-standard weight and measuring units in the reference literatures, to determine the dose of herbs in the prescriptions. Results : There are three types of units in non-standard weight and measuring units. These are 'Quantity measuring unit', 'Resembrance measuring unit', and 'Eye measuring unit'. And we found historical efforts and progresses for proper ways to convert non-standard weight and measuring units to standard weight and measuring units. Conclusions : This research will be the basic data for the standardization of prescriptions. Additional study was still required for precise weighing and measuring in Korean medicine and pharmacy.

The purpose of this study was to determine the effect of DHEA with dexamethasone on body weight and wet weight and relative weight of atrophied hindlimb muscles induced by dexamethasone treatment. $200{\sim}225g$ Wistar rats were divided into control(C), dexamethasone(D), dexamethasone and DHEA(DDH) groups. Dexamethasone was injected daily at a dose of 5mg/kg. DHEA was administered daily at a dose of 5mg/kg by oral ingestion during 7days. The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSSWIN 9.0 program. Body weight and muscle weight of plantaris and gastrocnemius of dexamethasone group decreased significantly compared with that of control group. Muscle weight of plantaris of DDH group increased significantly compared with dexamethasone group. Body weight of DDH group decreased significantly compared to control group, but relative weight of plantaris and gastrocnemius of DDH group increased significantly compared to control group. Based on these results, it can be suggested that DHEA administration during dexamethasone treatment can be suggested that DHEA administration during dexamethasone treatment can increase weight of atrophied plantaris muscle induced by dexamethasone treatment.

Purpose: This study aimed to identify factors (biological, psychological, interpersonal, and contextual factors) associated with the weight bias internalization of the Korean girls in early adolescence. Methods: This study used a cross-sectional design. Data was collected from 233 girls aged 12~14 years with a self-reported questionnaire. With multiple regression analysis, the factors associated with the weight bias internalization of the girls in early adolescence were analyzed. Results: Of psychosocial factors, fear to fat (anti-fat attitude) (β=.43, p<.001) was associated with the weight bias internalization of the girls in early adolescence. In addition, attachment with teachers (β=-.11, p=.029) of an interpersonal factor and perceived socio-cultural pressure regarding weight control (β=.34, p<.001) of a contextual factor were associated with the weight bias internalization of the girls in early adolescence. Conclusion: For releasing the weight bias internalization of the girls in early adolescence, decreasing anti-fat attitude and socio-cultural pressure regarding weight control should be primarily required through social efforts including community and school based interventions.

Objectives: Weight counseling is an inevitable process for patients with obesity who intend to lose weight; however, the contents of real-world counseling practices remain uncertain in Korean medicine (KM) practice. This study aimed to explore the structure and constituents of obesity counseling in KM. Methods: Qualitative methods were used to explore the structure of weight counseling and clinicians' approaches to weight counseling, particularly the advice and main constituents of weight counseling in KM. Nine KM clinicians (4 women, 5 men) from nine clinics completed face-to-face, individual and semi-structured interviews from September 2019 to February 2020 in Seoul, Daejeon, Cheonan, Seongnam, Asan, and Hwaseoug. The interviews were digitally recorded, transcribed verbatim, and categorized based on their constituents. Results: During weight loss counseling, the six principal constituents of KM identified were: planning with patients, motivation, correcting misinformation on weight loss, dietary and exercise advice, medication guidance, and customized guides for each type. Conclusion: Clinicians with in-depth knowledge about obesity prescribed personalized guidance for exercise, diet, and medication through an integrative approach. The study results provide an in-depth understanding of weight counseling in KM. These six constituents could guide the counseling provided by clinicians in obesity care.

작물 모델의 개발과 검증에 사용되는 생체중 자료는 파괴적 샘플링을 통해 얻어져 왔다. 파괴적 샘플링이 가지는 단점을 보완하기 위해 저가형 3D 센서인 Kinect 센서와 무료 공개 소프트웨어들을 사용하여 생체중을 추정하는 기법을 개발하였다. 특히, 많은 작물모델들이 개발되어 있지 않은 배추를 대상으로 입체이미지를 생성하여, 그로부터 얻어진 부피와 생체중 추정치의 신뢰도를 분석하고자 하였다. 크기가 다른 배추 결구 부위를 스캔하기 위해 Kinect 센서와, Microsoft가 무상으로 제공하는 Software Development Kit 내 Kinect Fusion Explorer 프로그램을 사용하였다. 개별 배추의 입체이미지를 생성하기 위해 3D 그래픽 편집 소프트웨어인 Meshlab을 활용하여 배경과 불필요한 물체를 수동으로 제거하였다. 또한, 불완전한 입체모델로부터 생체중 추정을 위해 3D 프린터 소프트웨어인 Makerbot Desktop 을 사용하여 배추를 생성하기 위해 필요한 플라스틱 필라멘트 소모량을 추정하였다. 입체모델 편집 프로그램인 Blender를 사용하여 부피를 추정하였을 때, 실제 부피에 비해 17.6%에서 2160.6% 범위의 상당한 오차가 있었다. 반면, 필라멘트 소요량은 실제 배추 생체중 변이의 98.7%를 설명할 수 있었다. 또한, 이들의 상관관계는 5% 수준에서 유의하였다. 이러한 결과들은 직접적인 부피 계산 절차를 제외하더라도 간편하게 생체중을 추정할 수 있음을 확인하였다. Kinect 센서를 사용하여 배추의 생체중 추정이 가능하다는 것이 확인 되었으나, 기존의 고가형 3D 센서에 비해 낮은 해상도와 주간에 활용이 어려운 점이 있다. 그럼에도 불구하고, 배추 생육 모델의 시계열적 검증 자료를 Kinect 센서를 이용하여 간편하고 신속하게 획득할 수 있어 모델의 불확도를 감소하는 데에 기여할 수 있을 것으로 판단된다. 따라서, 후속 연구에서 보다 저렴한 가격대의 3D 센서들을 대상으로 야외 및 주간조건애서 작물의 생체중 측정 가능성에 대해 검토하고 작물 모형 개발 및 개선을 위한 기술개발이 이루어져야 할 것으로 사료된다.

Weight reduction behavior is common among adolescent girls. The present study examined the status of weight reduction behavior and factors affecting the behavioral intention of weight reduction using the Health Belief Model (HBM) for female middle school students by weight category. Survey data was collected from three girl's middle schools in Gyeongju, Korea. A total of 299 female middle school students participated in this study. The questionnaire had questions about general characteristics, weight reduction behavior, and variables of HBM (perceived threat, perceived benefits, perceived barriers, cues to action, self-efficacy in dietary life and exercise, and behavioral intention of weight reduction). Descriptive statistics, Chi-square tests, ANOVA, and multiple regression analysis were applied to analyze the variables. A higher percentage of students in the overweight group attempted weight reduction than those in the underweight and the normal weight groups (P < 0.001). Among students who had attempted weight reduction, 73% tried diet therapy, while 78% tried exercise. Students in the normal and overweight groups showed significantly higher threat (P < 0.01) and cues to action (P < 0.001) than those in the underweight group. As for perceived benefits, barriers, and self-efficacy in dietary life and exercise, there were no significant differences among weight groups. Students in the overweight group showed the strongest intention of weight reduction and there were significant differences among the three weight groups (P < 0.001). Perceive threat (P < 0.01), cues to action (P < 0.001), and perceived self-efficacy (P < 0.01) were significantly associated to behavioral intention of weight reduction for all respondents. For the underweight group, perceived threat (P < 0.05) and perceived self-efficacy (P < 0.01) were the significant variables. For the overweight group, cue to action was the significant variable (P < 0.05).

The present study aimed to investigate the effects of maternal factors on body weight at hatching (day-old) and at six weeks of age in a commercial broiler line. A total of 6,765 records on body weight at day-old (BWTDO) and 115,421 records on body weight at six weeks of age (BWT6W), originated from a commercial broiler line during 14 generations, were used to estimate genetic parameters related to the effects of maternal traits on body weight of chicks immediately after hatch or six weeks thereafter. The data were analyzed using restricted maximum likelihood procedure (REML) and an animal model with DFREML software. Direct heritability ($h^{2}{_a}$), maternal heritability ($h^{2}{_m}$), and maternal environmental variance as the proportions of phenotypic variance ($c^{2}$) for body weight at day-old were estimated to be 0.050, 0.351, and 0.173, respectively. The respective estimated values for body weight at six weeks of age were 0.340, 0.022, and 0.030. The correlation coefficient between direct and maternal genetic effects for six-week-old body weight was found to be -0.335. Covariance components and genetic correlations were estimated using a bivariate analysis based on the best model determined by a univariate analysis. Between weights at hatching and at six week-old, the values of -0.07, 0.53 and 0.47 were found for the direct additive genetic variance, maternal additive genetic variance and permanent maternal environmental variance, respectively. The estimated correlation between direct additive genetic effect influencing weight at hatch and direct additive maternal effect affecting weight at six weeks of age was -0.21, whereas the correlation value of 0.15 was estimated between direct additive maternal effect influencing weight at hatch and direct additive genetic effect affecting weight at six-week-old. From the present findings, it can be concluded that the maternal additive genetic effect observed for weight at six weeks of age might be a factor transferred from genes influencing weight at hatch to weight at six-week-old.

This study investigated the relation between seasonal variation of clothing weight and its resting metabolic rate to determine the relation between proper living temperature and cold/heat tolerance. Thirty six subjects(18 males and females twenties) were composed to obtain the clothing weight(Total clothing weight) and resting metabolic rate for a year and grouped four seasons : spring (Mar-May) Summer(Jun-Aug) Fall(Sep-Nov) and Winter(Dec-Feb). The data of males and females were respectively divided into three groups by cluster analysis with clothing weight. 1. The resting metabolic rate of male(41.1kcal/m2/hr) was higher than that of female(33.2kcal/m2/hr). It is suggested there is gender difference in the resting metabolic rate(p<.001) 2. The resting metabolic rate of male and female was the highest in Winter. It is suggested there is seasonal variation in the resting metabolic rate(p<.001) 3. It was found that there was relation between clothing weight and resting metabolic rate. The difference of resting metabolic rate between Summer and Winter which is profitable to adaptation to living temperature was significant in light clothing weight in male as well as in female. 4. In comfortable sensation most subjects responded that he/she felt 'comfortable' except Winter. However the heavy clothing weight group felt 'a little uncomfortable' throughout all seasons. l In thermal sensation most subjects responded that he/she felt 'neutral' And then the heavy clothing weight group responded warmer in summer and cooler in winter than light clothing weight group. From the results it was confirmed that male and female showed seasonal variations in clothing weight and resting metabolic rate. Also the resting metabolic rate of male and female was influenced by the clothing weight. In short seasonal variation of resting metabolic rate was larger in light clothing weight group than in heavy clothing weight group. Therefore light clothing weight group is advantgeous in living temperature to improve cold/heat tolerance and it also shows that living with the light clothing weight may enhance the degree of adaptation to change of living environment

Objectives: This study sought to assess the prevalence and duration of weight-control or health functional food use, associated weight-control behavior, perception, and knowledge among university students. Methods: The subjects were 442 university students in Cheonju, Korea, and data was collected by a self-administered questionnaire. Both χ2 and t-tests were conducted for categorical and mean comparisons. Results: An estimated 62.7% (female 69.0%, male 54.8%) had ever attempted weight-control. Among these, an estimated 59.2% of females and 38.9% of males had used weight-control or health functional foods with significant gender difference. The weight-control foods commonly used included chicken breast, protein powder, low-fat milk and soymilk, and meal replacement drinks, while garcinia cambogia extract and green tea extract were frequently used as health functional foods. One of 10 (10.3%) consumers of weight-control foods reported ≥ 7 months use, with less frequent long-term consumption of health functional foods (4.2%). The average degree of satisfaction was 3.24 ± 0.92 for weight-control foods and 2.72 ± 0.97 for health functional foods on a 5-point scale, meaning 'slightly satisfied' and 'slightly dissatisfied', respectively. Females or students with an experience of weight-control reported poorer perceptions of their health and body image as well as a higher need for weight control. Besides, both male and female subjects felt a high need for correct information regarding weight-control methods. Conclusions: Our results provide a better understanding of the characteristics associated with the use of weight-control or health functional foods among university students and will be useful in developing a nutrition education program by incorporating correct body image, knowledge, and practical yet desirable practices for weight control.
