Because the previous simulation tool for attitude control of satellite was designed for the modeling of rigid body and PD controller, the attitude error can be made more than the limitation value for keeping for communication link, and then the communication link can be lost at moving of satellite. So, for rapid attitude restoration and design of stable and modernized controller, the modelling of rigid body and flexible body structure for moving GEO and LEO satellites were performed. Also the minimum time controller is designed for the rapid restoration of attitude error at communication broken and to minimize the disconnection period from ground communication system during the satellite stationkeeping. The linear regulator is designed using the space state vector that is better than accuracy and stability of PD controller. Firstly the simulation was performed for comparison of the rigid and stability of PD controller. Firstly the simulation was performed for comparison of the rigid and flexible models using PD controller and the case of the pitch angle changing by ground command, and the case of the periodic north-south stationkeeping are performed for the analysis of response characteristics of each controller when the attitude is changed. As a result, the flexible body model represents more sililar results of real situation than the rigid body model. The minimum time controller can restore 7 times rapidly than PD controller for its lost attitude. The linear regulator has several merits for capability of adaptation against the external disturbance, stability and response time. In future, we can check the estimated results using this satellite model and controller for real operation. Futhermore the development of new controller and training can be supported.

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.

The objects of this study were to classify the contents of life style of university students, to investigate the relationships between lifes tyle and appearance behavior(attitude toward appearance, body satisfaction, clothing attitude), and to examine how appearance behavior was influenced by life styles, male and female variables. The method of the study was survey research by using questionnaires. Subjects were 358(male 175, female 183) university students located in Junrabookdo province. In this statistical analysis, SPSS 11.5 for Windows Program was utilized to calculate frequency, percentage, mean, Factor analysis, Cronbach's ${\alpha}$, t-test, Pearson's correlation, Multiple Regression Analysis. The results of this research were as follows: Five dimensions of life styles were derived by factor analysis: 'digital orientation', 'material orientation', 'positive activity', 'achievement orientation', and 'frugality'. Male and female variables have significant effects on the life style and appearance behavior. Digital & material orientation were significantly higher for male than for female, whereas positive activity, achievement orientation, and frugality were significantly higher for female than for male. Attitude toward appearance and clothing attitude were significantly higher for female than for male, whereas body satisfaction were significantly higher for male than for female. Positive activity and achievement orientation had positive relations with appearance behavior. Need value of attitude toward appearance, body satisfaction, Clothing attitude variables except of attract sex attention was influenced by positive activity and achievement orientation of life style. As a conclusion, university students' life style and male and female variables constituted important characteristics which could affect appearance behavior.

Inertial Navigation System has been used extensively to determine the position, velocity and attitude of the body. An INS is very expensive, however, heavy, power intensive, requires long setting times and the accuracy of the system is degraded as time passed due to the accumulated error. Global Positioning System(GPS) receivers can compensate for the Inertial Navigation System with the ability to provide both absolute position and attitude. This study describes a method to improve both the accuracy of a body positioning and the precision of an attitude determination using GPS antenna array. Existing attitude determination methods using low-cost GPS receivers focused on the relative vectors between the master and the slave antennas. Then the positioning of the master antenna is determined in meter-level because the single point positioning with pseudorange measurements is used. To obtain a better positioning accuracy of the body in this research, a wireless internet is used as an alternative data link for the real-time differential corrections and dual-frequency GPS receivers which is expected to be inexpensive was used. The numerical results show that this system has the centimeter level accuracy in positioning and the degree level accuracy in attitude.

Personal appearance attitude about the ideal beauty is influenced by the context of the culture one belongs to. In a cultural sphere the higher public self-consciousness individuals have then the more sensitive one would be to the sociocultural pressure about thinness and thus the higher the expectations about the ideal appearance. Accordingly, in that culture one would have more body shame when they do not reach the ideal beauty standard. This study examines the difference between Korean and German culture, with a focus on the age group of university students who are especially sensitive to aesthetic consciousness. The results are as follows: There were differences of public self-consciousness, perceived sociocultural pressure, appearance internalization, appearance awareness and body shame between the two cultural spheres; in addition, Korean female university students were significantly higher in all the variables when compared to German female university students. The higher public self-consciousness and perceived sociocultural pressure then the higher the internalization of the ideal appearance; the ideal appearance awareness increased the body shame. In the case of the German female university student group, public self-consciousness influenced body shame directly; however, in case of the Korean female university student group public self-consciousness were not directly affective. Rather, perceived sociocultural pressures directly affected body shame and showed the difference between the cultural spheres. Finally, in regards to the direct effect about body shame, the German female university student group noted the influence of public self-consciousness as the most significant; however, the Korean female university student group noted the influence of sociocultural pressure as the most significant.

This study classified respondents by degree of obesity using Body Mass Index(BMI) and investigated the differences in self-esteem, food lifestyle, social-cultural attitudes towards appearance, and diet-related attitude and behavior such as trial number of diet, exercise time and period, use of diet information, interest in weight control, diet motivation, and dietetic therapy. A survey was conducted with 258 adults between the ages of 20 and 29 who lived in Daegu and Uijeongbu from November $17^{th}$ to December $14^{th}$ 2014. Data collected from the respondents were analyzed using descriptive statistics, factor analyses, analyses of variance and chi-square tests. This study divided the respondents into three groups (the underweight, the normal weight, the overweight) according to Body Mass Index. The results showed that there were significant differences in food lifestyle (health-conscious, popularity-seeking, taste-seeking), social-cultural attitudes towards appearance, exercise time and period, use of diet information, interest in weight control, diet motivation, and dietetic therapy among groups classified by degree of obesity. However, there were no differences in self-esteem, convenience-seeking, and trial number of diet among them.

The purpose of this study is to classify men in their 20s by their sex role attitudes, and to study their appearance management behavior and inner characteristic variables such as socio-cultural attitudes on appearance and bodily image, which are expected to influence the appearance management behavior of each classified group. For this, a survey of 393 males in the 20s in Seoul and metropolitan areas was conducted. Factor analysis, Cronbach's alpha coefficient, and F-test were conducted on the data. First, as a result of analysis on sex role attitudes, four groups were categorized: Masculinity, Femininity, Androgyny and Undifferentiation. Second, the analysis of individual variables resulted in appearance management behavior being separated into five categories: Interests in fashion, Proper choice of clothing, Importance of bodily attractiveness, Pursuit for personality and Complementation of physical weaknesses. The socio-cultural attitude on 'appearance' was sub-categorized into Internalization, and Awareness, while 'body image' was divided into Cognitive behavioral and Affective aspects. Regarding differences in socio-cultural attitudes for appearance, body image and metro-sexual lifestyle attitudes, the androgyny group produced the highest scores. Based on these results, it can be concluded that people who take care of their physical appearance, cope effectively with social and circumstantial requirements for happiness and success, and respond flexibly and affirmatively.
