This study was carried out to investigate perceptions of body image, body satisfaction, and dietary habits of beauty art major and non-major college students in Gyeonggi province. A total of 312 self-administered questionnaires (beauty art majors=145; non-majors=167) were analyzed. The means for height, weight, and BMI were 161.7 cm, 51.4 kg and 19.7, respectively. There were more majors who were underweight according to BMI classification than non-majors. Sixty-six percent of the subjects had previous weight control experience, and there was no significant difference between the majors and non-majors. The mean score for current body image was 4.61 out of a possible 9 points in the majors, which was significantly lower than 4.95 in the non-majors, and their perception of an ideal body image was thinner than their current body image. Those with more weight control experience had currently heavier perceptions of their body. The mean score for body satisfaction was 2.60 out of a possible 5 points, which was lower than the mean score for their attitudes toward the importance of their bodies. The mean score for dietary habits was 2.80 out of a possible 5 points, and there was no significant difference with dietary habits according to weight control experience or BMI classification. In both the majors and non-majors, there was a significant positive correlation between BMI and perception of current body image (p<0.001, p<0.001), and a negative correlation between BMI and body satisfaction (p<0.01, p<0.001). In the major students, there were significant positive correlations between dietary habits and body satisfaction (p<0.01), and attitudes toward the body importance (p<0.05); therefore, the greater their body satisfaction and body importance, the higher their scores for dietary habits.

This study explored the eating attitudes, dieting habits, weight perception and exercise behavior of Korean women. Self-reported questionnaires were administered to 724 Korean college students. Compared to males, female students felt themselves overweight and dissatisfied with their body and desired to lose weight although both groups were within the range of the national standard. Female students dieted more, while males exercised more. Eighteen percent of females showed disturbed eating behavior. The score for disturbed eating behavior was highly related to weight perception in the female students. These results suggest that Korean college women have a high prevalence of eating disturbances without having actual weight problems. A majority of the women desired to lose weight which may be due to the misperception of their body weight and fatness. However, they did not adopt appropriate strategies such as doing regular exercise to reduce their body weight.

Effective parenting attitudes have been known to be associated with children's health practices including dietary intake and physical activity. The objective of this study is to compare children's body weights and eating habits by maternal parenting attitudes. Data were collected at school (N = 396; 4th and 5th grade students) using self-administered questionnaires on maternal parenting attitudes, eating habits and physical activity. Parenting attitudes were categorized as 1 of 4 parenting attitudes (overprotective, authoritarian, democratic, and neglectful) using affection and control median cut points. Children's body weights, frequency of breakfast, eating out and fastfood, and physical activity were compared by maternal parenting attitudes. Children's body weights were related with mother's employment status (p < 0.05) and parenting attitudes (p < 0.01). Children of unemployed mothers were more likely to be overweight. Children of neglectful mothers (p < 0.01) were more likely to be underweight, compared with children of mothers with other parenting attitudes. Since, unfortunately, the number of children of neglectful mothers was very limited in this study, we could hardly assess eating habits of children of neglectful mothers. Children of authoritarian mothers ate breakfast more regularly (p < 0.05), but ate snacks less regularly (p < 0.01). Children of democratic mothers ate fastfood less frequently (p < 0.01) and ate snacks more regularly (p < 0.01). Meanwhile, children of overprotective mothers ate breakfast less regularly (p < 0.05) and ate out less frequently (p < 0.01). However, maternal parenting attitudes were not related to children's physical activities. In conclusion, the maternal democratic parenting attitude was associated with healthy eating habits including regular snack time and less fastfood. On the other hand, the maternal neglectful parenting attitude was associated with high risk of children's underweight. Understanding the mechanism through which parenting attitude is related with underweight risk and healthy eating habits may lead to the development of better interventions.

This study was conducted to investigate the changes of physical and psychological factors of obese children, obesity indices and blood serum levels, food habits and body and self-esteem after a weight control program. The results from this study were as follows: Participants of the study involved 20 boys (48.8%) and 21 girls (51.2%) totaling 41 children. Children's weight control experiences were 90.2% and parents' were 59.5%. Among methods of weight control, children and parents both used exercise and reduced amounts of meals. Sixty-one percent of the children had breakfast almost everyday. The reasons of skipping breakfast were having no time to eat by 44.4% and 50% of children watched TV while having a meal and they considered taste (55.3%) and nutrition value (21.1%) when choosing food. After the weight control program, the children's body fat percent (%) significantly decreased from 40.3% to 35.4% (p < 0.01). There was significant difference of boys and girls' hip circumferences (92.9 cm, 91.4 cm, p < 0.01) after the program but there was only a slight change in their WHR (0.91, 0.92). Girls' waist circumferences significantly decreased from 75.0 cm to 73.0 cm (p < 0.05) and there was a significant increase in HDL-cholesterol, 50.0 (mg/dL) to 55.2 (mg/dL), (p < 0.05). Knowledge levels of obesity significantly increased from 2.5 to 5.1 in the girls' cases (p < 0.001). Nonetheless, attitudes of weight control and food habits score had not changed a lot. After the program, both the boys and girls' body-esteem had significantly increased (p < 0.01) but self-esteem had not changed. These results suggest that a body weight control program must be included in nutrition education, exercise and psychotherapy to improve body and self-esteem of obese children.

The purpose of this study was to provide basic informations for educating juveniles on desirable body image recognition by examining their body image recognition and comparing and finding problems according to gender and body mass index (BMI) in middle school students. The average age of the subjects was 15, their average height was 162.5 cm, their average weight was 53.5 kg, and their average BMI was $20.1\;kg/m^2$. Male students wanted to gain weight and female students wanted to lose weight. As for body shape, female students thought that they were fat more often than male students. Also the more overweight the students were, the higher their concerns and experiences toward weight control. Among weight control methods, exercise scored highest in all BMI groups. Over 80% of the respondents answered that their weight control effort were not systematic such as via professional counseling. As for the frequency of eating breakfast and dinner in female students, the more a student was overweight, the lower their frequency of eating breakfast and dinner. Many respondents answered that a typical meal time was '10~20 minutes'. The average eating habit score for all subjects was 38.0. The eating habit scores of male students were significantly higher than those of female students, and there were no significant differences among BMI groups. Eating habit score of 'I have more than two meals with rice everyday' in female overweight group was significantly higher than those of other two groups. These results indicate that the female students' degree of preference for a slim body shape were higher than those of male students. In addition, weight control by students is not systematic through professional counseling; instead they attempt to control their weight by themselves such as a meal skip, which lead to potential danger that they may lose weight carelessly. Therefore, correct body image recognition is greatly needed, and families and schools should make ceaseless efforts to help students properly control their weight and have correct eating attitudes.

This study was designed to find characteristics and patterns in Obese student's attitudes toward the school obesity program. Q-methodology was used as a research tool and the data were collected from October 1st, 1997 to April 30th, 1998. The results are as follows: 1. Q-sampling has been derived from the literature, and in-depth interviews of different groups (primarily students and normal weight students. Its credibility and validity were also tested by nursing and Q-methodology professors as well as school nurses. 34 statements were selected from a total of 197 statements collected. 2. In a P-sampling, 38 samples were selected. 3. Based on a 9 point scale, the selected respondents rated their operant definition of Obese student's attitudes toward school obesity programs. 4. The results of the above procedures were analyzed by a PCQ program. The results revealed that there are four attitudes toward the school obesity program. These four are the following: 1) First, demand for little exposure, which consisted of thirteen subjects. 2) Second, demand for other's support, which consisted of six subjects. 3) Third, demand for self-control, which consisted of four subjects. 4) Forth, demand for other's stimulation and motivation, which consisted of five subjects. In conclusion, this study discovers obese students have attitudes toward the school obesity program. By identifying the nature of each of the these types this study can be useful to manage and develop a school obesity program.

The study examined BMIs, physical strength, activities, and the attitudes and behavior toward weight control among 7,968 Korean students{2,435 5th graders from elementary schools(ESs), 2,524 2nd graders from middle schools(MSs), 2,739 2nd graders from high schools(HSs)} nationwide. Compared to the 1987 data, there were increases of height(3-6cm) and weight(3-8kg), but decreases of physical strength and exercise. Lack of 'regular exercise' among girls from MSs and HSs and higher proportion of time spent on watching TV and using a computer for elementary schoolers were particularly noticeable. Proportions of students who were satisfied with their body weight were 49% for ESs, 35% for MSs, and 29% for HSs. There was no relationship between subjective and objective evaluations of body weight. Diet rather than exercise was more frequently chosen as a method of weight control. Compared to boys, girls showed stronger association between the amount of exercise and the subjective body weight in MSs and HSs, however this association was not found for the subjects from HSs. Values for the 50th percentile of BMI of boys and girls were 18.4 and 17.7 for ESs, 19.9 and 20.1for MSs, and 21.4 and 20.6 for HSs. In MSs and HSs, boys with BMI between 15th to 85th percentiles were physically stronger than those whose BMIs were lower than 15th kor higher than 85th percentiles. For the other groups, there was a trend of a positive relationship between BMI and physical strength. Based on the analyses of BMI and physical strength, this study suggests 22 and 21 for upper grades in ESs, 24 and 23 for MSs, and 27 and 25 for HSs as the respective cut off points of BMI for weight control n boys and girls. A need for implementing nutrition education program focused on weight control is also suggested.

A reduced order observer is developed for depth control of a hybrid underwater glider which combines the good aspects of a conventional autonomous underwater vehicle and a underwater glider. State variables include the center of gravity of the robot and the weight of the buoyancy bag, which can not be directly measured. By using the mathematical model and available information such as directional velocities, accelerations, and attitudes, we developed a Luenberger's reduced order observer to estimate the center of gravity and the buoyancy weight. By simulations using Matlab/Simulink, the efficiency of the proposed observer is shown, where a LQR controller using full state variables is adopted as a depth controller.
