Objectives : This study was conducted to examine the mediating function of body weight perception (BWP) on the relationship between body mass index (BMI) and unhealthy weight control behaviors (UWCB: e.g., fasting, or taking diet pills or laxatives) and between BMI and depressed mood, and to explore the effect of distorted BWP on UWCB and depressed mood among adult women. Methods : A regionally representative sample of 8,581 women aged 20-64 years residing in Seoul, the capital of Korea, completed the 2001 Seoul Citizens Health Indicator Survey which provides self-reported information about height, weight, BWP, UWCB, depressed mood, demo graphic/socioeconomic characteristics, and health-related behaviors. Data were analyzed using bivariate and multivariate logistic regression. Results : BMI was significantly associated both with UWCB and depressed mood, even controlling for all covariates. However, the magnitude and significance of each association was considerably attenuated when BWP was taken into account, indicating that BWP functioned, in part, as a mediator between BMI and UWCB and between BMI and depressed mood, respectively. Among the combinations of BMI and BWP, women who perceived themselves to be heavier than their actual BMls appeared more likely to use UWCB, whereas women who had a distorted BWP, either underestimation or overestimation as compared with their BMIs, tended to be at greater risk for depressed mood than those who had an undistorted BWP. Conclusions : These findings suggest that how women perceive their body weight may be an important predictor and/or mediator of UWCB and depressed mood among adult Korean women.

This research looks at the innovative product characteristics, environmental properties, and personal attitudes as antecedents of consumer's perceived usefulness and easiness of product usage. And the attitudes toward digital convergence products and its acceptability as consequences. The results indicate that relative advantage, expectation for better product, the social influence, mass communications, and attitudes toward the new technology, significantly influence the perceived usefulness. The current research revealed that perceived usefulness is more influential over perceived easiness on the formation of positive attitude toward the product. The users of digital convergence products put more weight on the availability of the product functions rather than easiness of use.

This study was made to find out the relationship between the eating attitude influenced by an eating disorder and nutritional knowledge among 441 female college students. A self-report questionnaire was used, and the summary of the results are as follows : Almost all of the surveyed female college students were in criteria of standard weight, however they regard themselves more obese than what their actual body shape normally shows. The correlation between perceived body shape and the eating attitude influenced by an eating disorder turned out to be high(p<0.001). The significant level of correlation between the perceived body shape and the eating attitude test-26(EAT-26) scores showed much higher than that obtained between actual shape, degree of obesity and eating attitude test-26(EAT 26) scores(p<0.001). There was no significant level of correlation between the defree of obesity and the average score of nutritional knowledge obtained out of the total questionnaire, however it showed significant level of correlation between macronutrient and roughage(p<0.05), fat and calorie requirement(p<0.01). There was significant correlation among perceived body shape, actual weight and eating attitude influenced. by an eating disorder. Thus the correct perception of body shape turned out to be an important factor in obtaining the desirable eating attitude and adequate nutritional knowldege.

The purpose of this research is to study the recognition of real somatotype and body of college women. The study was carried out by classifying somatotypes into three categories based on the body index; slim, normal, and obese somatotype. The subject of this study was 106 college women, and real measurement and survey were used. Data was analyzed by SPSS 12.0 and cross tabulation analysis, t-test, Anova, and correlation analysis were operated. The result is as follows. 1. The height of the subjects was 163.5cm, weight was 53.3kg, Rohrer index was 1.2, BMI was 19.9, Vervaeck index was 84.4 and the classification based on the body index belonged to the normal group. 2. The characteristics of groups divided by the body index are that slimmer groups is longer in length factor and smaller in the factors related with volume than other groups. The characteristics of groups classified by self-consciousness shows significant difference in all girth factors, back intersyce breadth, front intersyce breadth, neck to nipple length, and nipple to nipple breadth. 3. Conscious about the somatotype with using body index generally shows similarity. In the length factor including height, slim somatotype group is perceived as longer than normal somatotype group, and in the girth factor including weight, normal somatotype group is recognized as bigger and thicker than others.

This study was conducted to provide information about weight control behavior in adolescent females. To explain the behavior intention of dieting, conceptual framework based on "Social Support, Control and the Stress Process Model" and "Theory of Reasoned Action" was used. The survey was carried out by self-questionnaires with 463 female high school and college students in Daegu. Analysis of data was done using mean, correlation and multiple regression analysis with the SAS computer program. A society preoccupied with thinness gives a burden to women, and this burden may stress dissatisfaction with body image. Social perception of ideal body image except parents' perception, and salient others'perception, and salient others' expectation of subjects' body image except parents' expectation, were much thinner than normal figures in this study. The influencing factors for behavior intention of dieting of the subjects were perceived stress and attitude toward diet behavior, especially beliefs of behavioral outcome. Influencing factors related to perceived stress-that is dissatisfaction of body image-were current figure, social perception of body image, effect of mass communication and others' estimation of subjects' body image with self-comparison with others, in order.th others, in order.

Purpose: The goal of this study was to examine body image satisfaction and perception according to weight status, and to investigate those associations with dietary habits and nutritional status among preadolescent children. Methods: Body image and dietary habits and intake were assessed in 134 elementary school students in grade 4. Children were categorized according to normal and overweight or obese groups. Figure rating scales were used to assess body image perception (identification of perceived current body size) and dissatisfaction (difference between perceived current body size and ideal body image). Results: There were sex differences in body image perceptions. Normal-weight girls, overweight or obese girls and boys were more likely to desire a leaner body size than their perceived body size compared with normal-weight boys. Body image satisfaction and perception showed an association with weight status. More overweight or obese children indicated dissatisfaction or underestimation of body image than normal-weight children. Children with body image dissatisfaction due to heavier perceived body size than ideal body image showed lower frequencies of consumption of meals and vegetables, compared to those who were satisfied with their body image. Children who underestimated their body image were more likely to have a lower frequency of breakfast and meal regularity and a higher frequency of eating out of home or food deliveries than those with accurate body image perception. In addition, body image underestimation showed an association with lower intakes of protein, dietary fiber and calcium, and the higher percentage of calories derived from fat. Conclusion: Body image dissatisfaction as well as underestimation in children before puberty showed an association with overweight or obesity, and was also related to unhealthy dietary habits. These findings highlight the importance of accurate perception and satisfaction with body image in preadolescent children in order to prevent development of obesity in adolescents and adults.

Purpose: This study was done to identify perceived body image, intentional caloric restriction and physical manifestations of unbalanced nutrition according to the Body Mass Index (BMI) in elementary school students. Methods: The research design was a cross-sectional descriptive study. Data collection was done by using a structured questionnaire that consisted of 34 items. Participants were 151 students in 5th and 6th grades of elementary schools in Gangwon province. Frequency and percentage, one-way ANOVA, and $\chi^2$-test with SPSS WIN 12.0 were used to analyze the data. Results: In elementary school students, over-weight/obesity and normal weight groups reported that they would be satisfied with a thinner body image compared to the present image. The score for intentional caloric restriction was significantly higher in the over-weight/obesity group than in the under-weight group. In physical manifestations of unbalanced nutrition, students in the under-weight group frequently were pale and had dry skin, whereas the over-weight/obesity group reported frequent upper respiratory symptoms. Conclusion: The results suggest that elementary school students need to develop the perception of an adequate body image and to avoid inadequate caloric intake if promotion of the child's growth and development is to be without physical manifestations of unbalanced nutrition.

The purpose of this study was to determine the recognition of body image and food behavior factors according to the BMI. The subjects of this study were 242 7th grade students resided in San Francisco area. The degree of recognition for self-estimated physique of subjects by gender and by race showed no significant differences by gender but significant differences by race, showing that 20.0% was considered as underweight in Asian and 7.5% was considered as underweight in White students. This showed the same tendency as actual physique status (BMI). Also, the ratio of being recognized as more than overweight was 17.3% in Asian, 23.3% in Hispanic, and 13.4% in White students. In case of female students, the ratio of dieting experience was 63.3%, and 49.3% of White students and 63.3% of Hispanic students experienced dieting. In case of students answered not healthy, their body weight were significantly higher than those answered as healthy, and the BMI was also over 19, showing significant differences. Thus cases that answered as not healthy had greater body weight and BMI. Also it showed that frequent dieting experience is related to higher height and weight. The analysis of food behavior factors perceived by body shape showed that the group perceived itself as overweight consumed more 'fast food' but had low scores in 'vegetables' intake, with frequent intake of 'soda' and tendency to 'overeat'. Also, the tendency for 'balanced life' was significantly lower and for skipping breakfast was significantly higher, suggesting problematic food behavior.

The purpose of this study is to measure a perceived joint discomfort in the seated and standing position, and to provide ranking systems of perceived joint discomfort. Nineteen mole subjects with no history of musculo-skeletal disorders participated in the experiment. Their physical characteristics were: age $-25.4{\pm}2.7$years, stature $-171.9{\pm}6.0cm$, and body weight $-67.1{\pm}7.0kg$. The results showed that the perceived joint discomforts were different depending upon the joints involved in motion and their movement directions (degree of freedom of motions), which implied that the human body motions and their degrees of freedom should be classified into several distinct classes that need to be assigned different weights of postural stress. Therefore, three ranking systems based on the perceived joint discomforts were suggested, which were classified by the degree of freedom of motions and joints, by only degree of freedom motions, and by joints involved in motion, respectively. In the seated position, the hip movement was the most stressful, the bock was the second, and the shoulder was the third. Likewise, in the standing postures, the hip was the most, the bock was the second, and the ankle was the third. It was expected that these joint motion ranking systems could be used by practitioners of health and safety to improve the comfort of working postures in industry.

Objectives: This study analyzed the relationship between BMI (body mass index), perceived health status, and oral health behaviors of schoolgirls. Methods: This study utilized data from the 13th (2017) Korea Youth Risk Behavior Web-Based Survey. A total of 29,337 schoolgirls were analyzed. Statistical analysis was performed using PASW Statistics 21.0 (SPSS Inc., Chicago, IL, USA). Results: Compared to the obese group, the rate of being recognized as healthy was 1.882 times higher in the normal-weight group and 1.623 times in the underweight group. The rate of using supplementary oral hygiene devices was 1.383 times higher in the underweight group and 1.091 times in the normal-weight group than in the obese group. Compared to the obese group, the experience rate of the sealant was 1.407 times in the underweight group. Compared to the obese group, the scaling experience rate was 1.282 times higher for the underweight group and 1.205 times for the normal-weight group. Conclusions: These results suggest that individual health behaviors are interrelated. There is a need for an integrated approach in the planning and implementation of future health promotion strategies, and it would be useful to design a program that considers health characteristics such as BMI.
