The purpose of this study was to investigate health-related habits, dietary habits, depression, stress, satisfaction of body weight, mini-dietary assessment (MDA) and dietary behaviors according to self-rated health among 255 university students in Kyungnam province. Statistical analyses were performed using the SPSS software package (version 19.0). The average ages of the subjects were 21.1 years. Participants were asked their self-rated health and 109, 105 and 41 students answered themselves as "healthy", "normal" and "unhealthy", respectively. The pocket money (P<0.05) was related with self-rated health, and meal frequency (P<0.01) of healthy group was higher than that of the unhealthy group. The self-reported depression level (P<0.01) and the score of depression (P<0.05) of the healthy group were lower than those of the unhealthy group. The self-reported stress level of the healthy group (P<0.05) was higher than that of the unhealthy group. The scores of nutritional behavior (P<0.05) and MDA (P<0.01) of the healthy group were higher than those of the unhealthy group. The scores for intakes of meat, fish, egg or beans, cereals and vegetables except kimchi, fruits, balanced diet and various foods were higher in the healthy group than in the unhealthy group. Our results suggest that pocket money, high meal frequency, low depression, satisfaction of present body weight, and good dietary behavior might influence good perception of self-rated health.

The purpose of this study is to verify effects of female college students' self-image on appearance management behavior and investigate the differences caused by TV involvement and entertainer imitation on the appearance managing behavior. Respondents of the survey were 424 college females living in Seoul and Gyeonggi province. For statistical analysis, factor analysis and multiple regression were conducted using SPSS 18.0 program. The results of this study are as follows: First, self-image among college females were composed of 5 factors, which were active image, feminine image, intelligent image, gentle image and modern image. Second, college females' self-image influenced on skin management behavior, hair management behavior, make-up behavior, clothing behavior and weight management behavior significantly. Specifically, as respondents' active image and modern image are getting higher, they tend to perform skin management behavior, hair management behavior and clothing behavior. As female students' intellectual image and modern image were getting higher, more positive effects were found on make-up behavior. As female students' gentle image and active image were getting higher, there was more positive effects on weight management behavior. But, female students' self-image didn't show significant effects on cosmetic surgery behavior. Third, when subjects' TV involvement was high, self-image made greater effect on skin management behavior and cosmetic surgery behavior than those with low TV involvement. Forth, when entertainer imitation was high, self-image made greater effects on skin management behavior, hair management behavior, clothing behavior, make-up behavior, weight management behavior, cosmetic surgery behavior than those with low entertainer management.

Purpose: The incidence of chronic diseases is increasing and the age of onset is decreasing in South Korea. Healthy eating habits to prevent chronic diseases are established in adolescence. This study verified the identified factors and dynamics that affect diet self-assessment for sustainable adolescent health and the prevention of chronic diseases. Methods: Data were collected from 492 middle and high school students in South Korea from June to July 2018, and the participants answered a questionnaire on dietary safety management competency for sustainable health. Results: The healthy dietary self-assessment scores of overweight/obese adolescents and adolescents who perceived their health as normal were significantly lower than those of other groups. Factor analysis verified the validity of the items that comprised each study area before a multiple regression analysis was used to investigate the factors affecting healthy dietary self-assessment. Sweet and salty diets, anxiety, food and nutrition knowledge, weight management knowledge, stress management, exercise, basic eating habits, and healthy eating habits significantly affected healthy dietary assessment among adolescents. A higher perception of one's health indicated a higher healthy dietary self-assessment, dietary safety knowledge, and health management practice scores (p < 0.01). Factors like healthy dietary self-assessment, food and nutrition knowledge, and weight management knowledge appear to have a significant correlation with other identified factors, except overeating. The adolescents' awareness, knowledge, and dietary safety practices influenced healthy dietary self-assessment, which can prevent chronic diseases and achieve sustainable health. Conclusion: This study illustrated how the adolescents' awareness, knowledge, and practices of dietary safety influenced their healthy diet self-assessment. The results indicate that diet-based health management competency education relative to the adolescents' self-perception and weight levels should be implemented.

A global path planning algorithm using modified self-organizing feature map(SOFM) which is a method among a number of neural network is presented. The SOFM uses a randomized small valued initial weight vectors, selects the neuron whose weight vector best matches input as the winning neuron, and trains the weight vectors such that neurons within the activity bubble are move toward the input vector. On the other hand, the modified method in this research uses a predetermined initial weight vectors of the 2-dimensional mesh, gives the systematic input vector whose position best matches obstacles, and trains the weight vectors such that neurons within the activity bubble are move toward the opposite direction of input vector. According to simulation results one can conclude that the modified neural network is useful tool for the global path planning problem of a mobile robot.

Purpose: This study explored the relationships of maturity fears and appearance interest(interest in appearance, interest in weight) with self-concept among girls with precocious puberty. Methods: The participants for this study were 120 elementary school students (8 to 10 years old) and their parents from two hospitals located in Chungcheong Province. Data were collected from January to February 2019 using self-reported questionnaires. The collected data were analyzed using descriptive statistics, the independent t-test, the Mann-Whitney U test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression analysis in SPSS for Windows version 23.0. Results: Statistically significant negative correlations were found between self-concept and maturity fears (r=-.34, p<.001) and interest in weight (r=-.29, p=.001). Maturity fears were identified as a factor affecting the self-concept of girls with precocious puberty (β=-.34, p<.001). This variable explained 11.5% of the variance in the self-concept of girls who experienced precocious puberty. Conclusion: This study confirmed that maturity fears had a major influence on self-concept in girls with precocious puberty. The results of this study can be used as basic data for the development of a psychosocial nursing intervention program for girls who experience precocious puberty.

This study investigated the relationships between eating disorder risk, body image perception, weight control, and dietary habits in Korean women. Body shape perception, the Eating Attitude Test (EAT-26) and dietary habit information were collected by a self-administered questionnaire to 373 adult women and the data were analyzed by the Chi-square test. 31.4% of the women were classified in the eating disorder group by a score of over 20 points on the EAT-26. Compared to the normal group, more women in the eating disorder risk group perceived that a thin body shape was the ideal body shape and were dissatisfied with their body shape. This group was also more interested in weight control and more likely to try weight control methods. The eating disorder risk group was more likely to skip meals and snacks than the normal group. In addition, they had a greater appetite and a higher frequency of overeating than the normal group. Over 30% of the Korean women surveyed were categorized at high risk of eating disorders. They were more likely to overestimate body weight and shape and tried to control their weight by inappropriate methods. To prevent eating disorders in adult women, nutrition education programs should incorporate strategies to change inaccurate self-body image and to disseminate information about healthy weight control methods.

The purpose of this study was to investigate the effects of body image, body dissatisfaction, and drive for slimness, as mediated by self-esteem and depression, on eating disorder behavior according to gender The subjects of this study were 243 male and 323 female university students from Chungbuk National university in Cheonju. On the basis of previous literature, the theoretical model was specified and estimated for the adequacy of statistical fit for male and female students separately. The proposed theoretical model was supported by the data and fitted adequately. As expected, body image, body dissatisfaction, and desire for thinness had a direct effect on self-esteem for female students. However, whereas body image and body dissatisfaction directly influenced on male students' self-esteem, while desire for gaining weight had no direct effect. Eating disorder behavior in female students was predicted by body dissatisfaction, body image, and self-esteem. For male students, desire for gaining weight and self-esteem strongly predicted eating disorder behavior. The results indicate that the influence of body image, body dissatisfaction, and desire for thinness on eating disorder behavior can be mediated not by depression but by self-esteem.

The purpose of this study was to analyze characteristics of the obese children in depth and provide basic information for a comprehensive educational program for the obese children. Physical and biochemical characteristics, nutrient intake, and self-esteem, etc. of 16 obese elementary school children (OC) and 14 normal weight elementary school children (NWC) were examined. Self-esteem was measured using Likert-type scales with description. Plasma levels of total cholesterol, LDL-cholesterol, and glucose of OC were higher than those of NWC. Dietary intake with a lunch provided more energy and vitamin B1 in OC than in NWC. Physical appearance and athletic competence among self-esteem in OC were lower than in NWC. However, there was no significant difference in physical activity between OC and NWC. In OC, atherogenic index was positively related with waist circumference, obesity index and BMI while athletic competence self-esteem was negatively related with them. It is recommended that the children should receive the comprehensive educational program for improving children' dietary behavior and their self-esteem.

Purpose: The purpose of this study was to identify congruence between self-perception and objective status of obesity according to %Fat, and to investigate health promotion lifestyle in college women. Methods: The participants were a convenience sample of 392 college women who were eligible and agreed to participate in this study. Respondents were asked questions using a health promotion lifestyle profile and were evaluated for their body composition using InBody 3.0. The data were analyzed with SPSS 14.0 program, which was used for Chi square, ANOVA, and post-hoc comparison with Scheffe. Results: The major findings were as follows; 1) Overall, 41.8% of participants misclassified their perceived status of weight by %Fat standards and kappa was 0.329. 2) Two percent were underweight by BMI but overweight by %Fat and 39.0% normal weight by BMI but overweight by %Fat. 3) There were significant differences in health promotion lifestyle according to self-perception of body weight but there was no difference in health promotion lifestyle according to %Fat standards. Conclusion: These findings suggest the necessity for development and application of tailored health promotion program based on self-perception of body weight and %Fat in order to reform incorrect body image and health behavior in college women.
