Purpose: This study explored the feasibility of a 12 week self-efficacy based exercise intervention for overweight and obese college students. Method: A repeated measure, 4-group randomized controlled design was used. Students were recruited from two universities. in Seoul. Korea using: (1) flyers either on the campus bulletin boards or in campus restrooms: (2) advertisement on campus e-board: and (3) self-referral. Inclusion criteria were: (1) Korean college students aged 18 to 29: (2) BMI >23: (3) viscerally obese: and (4) accessible to a phone and a computer. Participants completed three self-reported questionnaires: socio-demographic questionnaire (at the baseline), Exercise Self-Efficacy Scale (at the baseline and $12^{th}$ week), and Physical Fitness sub-subscale (at the baseline and $12^{th}$ week). Additionally. physiological data (height, weight, blood pressure) were collected at the baseline and $12^{th}$ week. Descriptive statistics and a two-way mixed ANOVA were performed using SPSS12.0. Results: No significant group difference was observed. However. students with increased exercise self-efficacy during the program showed better physical fitness in the $12^{th}$ week. When students' physical fitness was enhanced. the physiological factors were improved. Conclusions: Self-efficacy based exercise intervention may be applicable and acceptable to the college students. It is necessary to conduct a replicated study with a larger sample and an elongated intervention period.

The purpose of this study is to examine the differences in appearance management behaviors and demographic variables among groups classified by the appearance management motives. The questionaries are administerd to 493 female and male adults above 20 years old in Seoul, Kyeonggi-do, Daegu and Kyungpook regions. For analysis of data from 478 respondents, descriptive statistics, factor analysis, cluster analysis, Cronbach's ${\alpha}$, ANOVA, Duncan test and ${\chi}^2$ test were applied. We show the following results: First, factor analysis for appearance management motives extracted three factors such as self-development, emphasis on the trendy appearance, and sexual appealing motive. Factor analysis for appearance management behaviors extracted four factors such as weight training, surgery/skin care, hair care and clothing selection. Second, three groups of the appearance management motives were classified into such as the social self-management type, the sexual appealing self-management type, the passive appearance management type. The social self-management groups are more interested in self-development, emphasis on the trendy appearance, and sexual appealing motive. And they are also more involved in appearance management behaviors: clothing selection is the most pursuing appearance management behavior. Third, among the demographic variables, the single and female in 20s and 30s with higher level of education belonged to the social self-management group. In this contribution, we find significant differences in the appearance management behavior and demographic variables classified by the appearance management motives.

Objectives : This study examined the association between body mass index(BMI) and psychological factors; self-esteem, depression, restraint eating, disinhibition, and hunger. The difference of TFEQ(restraint eating, disinhibition and hunger) was analyzed in variety of current diet situations. Methods : The research was based on a sample of people who visited our website and submit the result of self test(self-esteem n=3183; TFEQ n=5167; BDI n=2457). Results : Self-esteem and BDI was slightly correlated with BMI. There is negative correlation between restraint eating and BMI and positive correlations were observed between hunger and BMI, and disinhibition and BMI. We studied diet situation and eating habits. We divided the sample into 4 groups in accordance with self-submitted result: non-diet group(n=2806), diet-failed group within 3 months group(n=371), maintaining group after successful-diet(n=233), on-going diet group(n=1757) As to restraint eating, non-diet group showed the lowest score in restraint eating and maintaining group after successful-diet showed the highest. The score in disinhibition and hunger was significantly lower in maintaining group after successful-diet group than one in diet-failed group. Conclusion : These results suggest that it would be essential to treat these psychological factors such as depression and self-esteem in weight loss program. Considering the result in diet-situation and TFEQ, we insist that restraint-eating and disinhibition should be controlled. If these psychological factors were not treated in place, even the successful diet might turn out to be a worse situation like binge-eating

Depth estimation is a key technology in 3D map generation for autonomous driving of vehicles, robots, and drones. The existing sensor-based method has high accuracy but is expensive and has low resolution, while the camera-based method is more affordable with higher resolution. In this study, we propose self-attention-based unsupervised monocular depth estimation for UAV camera system. Self-Attention operation is applied to the network to improve the global feature extraction performance. In addition, we reduce the weight size of the self-attention operation for a low computational amount. The estimated depth and camera pose are transformed into point cloud. The point cloud is mapped into 3D map using the occupancy grid of Octree structure. The proposed network is evaluated using synthesized images and depth sequences from the Mid-Air dataset. Our network demonstrates a 7.69% reduction in error compared to prior studies.

Purpose: The objective of this study was to examine the effect of the body shape discordance, the difference between true body type based on body mass index (BMI) and self-recognized body image, on nutrient intake, weight control attempt, and mental health in Korean adults. Methods: Subjects were persons aged 19~64 years (4,382 men and 6,226 women) who participated in the 2010~2012 Korea National Health and Nutrition Examination Survey. Subjects were categorized as RL (Group recognized as lighter than BMI criteria), RA (Group with agreement between BMI criteria and self-recognized body image), and RH (Group recognized as heavier than BMI criteria) according to the difference between actual body type based on BMI and self-recognized body image. Results: Means of BMI in RH groups were lower than or equal to that of RA groups in all groups. No significant differences in total energy intake were observed among the three groups in men, but total energy intake was higher in the RL group than in the RH group in 30~49 year old women. Proportion of carbohydrate was the highest in the RL group among 30~49 year old women. RH groups paid more attention to weight control and had less weight gain than other groups. Higher proportions of depressive symptoms were reported in the RH group in 19~29 year old men, while a higher proportion of depressive symptoms were reported in the RL group in 50~64 year old men. Conclusion: The current findings suggest an association of perceiving body shape with energy intake, weight control attempt, or depressed mood in some age groups. Body image perception can influence eating, weight control attempt, and depressed mood, therefore proper body image perception should be established in Korean adults.

This quantitative study was conducted to examine the relationship between weight control behaviors and disordered eating patterns in some university students. This study used a cross-sectional study design. A total of 347 students from three universities participated in this study (88 male and 259 female) Eating disorders were assessed using the Eating Attitudes Test (EAT-26); a score of =20 identifies individuals who likely have an eating disorder, including anorexia nervosa and bulimia nervosa. A score for healthy dietary behaviors was obtained by self-assessment on a healthy diet scale (20-item questionnaire), and the severity of any state-trait anxiety was calculated by the state-trait anxiety inventory (40-item questionnaire). In the analyzed results, the percentage of participants with experience of weight control was 58% in male and 73% in female. The subjects with a high risk of an eating disorder (score of =20 of EAT-26) were 44.3% ($mean{\pm}S.D;\;18.9{\pm}13.4$) of the males, and 57.9% ($mean{\pm}S.D;\;23.2{\pm}11.6$) of the females. Higher Body Mass Index (BMI) was significantly related with an increased risk for an eating disorder in females, but not in males. In the group who had attempted weight control of all types, there was a severe risk of an eating disorder. Increased eating disorder risk was significantly related with weight control behaviors such as a higher number of attempts at weight control, having used medication, having experienced side effects, and having experienced disease for both sexes. Therefore, the results of this paper showed that detrimental behaviors of weight control are connected to an increased risk of eating disorders. Consequently, education regarding the correct, behaviors of weight control is necessary to prevent eating disorders in adolescents.
