기존의 위성제어용 시뮬레이션 툴은 위성 모델을 강체로 보고, 비례-미분(Proportional-Differential)제어기를 사용하기 때문에, 이동하는 위성의 경우 오차한계범위를 벗어나 통신이 두절되는 현상이 발생할 수 있다. 따라서, 본 논문은 신속한 자세회복 및 안정된 진보적인 제어기의 설계를 위하여 이동하는 정지궤도 및 저궤도 위성에 대하여 위성을 강체 및 유연체 구조로 모델링하고, 통신두절시 신속한 자세 회복을 위한 최소시간 제어기 설계와 위성의 위치 제어시 발생하는 통신중단을 최소화 하기 위하여 기존의 PD제어기보다 정확하고 안정된 선형조절기를 상태공간 벡터를 사용하여 설계하였다. 시뮬레이션은 먼저 강체 모델과 유연체 모델을 비교하기 위하여, 이동하는 정지궤도 및 저궤도 위성에 대하여 PD제어기를 사용하여 시험되었으며, 자세이동시의 제어기의 응답특성을 분석하기 위하여, 지상의 명령에 의한 위성의 피치각을 변경하는 경우, 주기적으로 수행되는 남북 궤도 유지에 대하여 수행하였다. 그 결과, 강체모델에 대비하여 유연성 모델이 실제 상황에 근접한 결과를 가져다 주었으며, 최소시간제어기는 PD제어기 대비 약 7배 이상 빠르게 신속한 자세 회복을 가져다 주었으며, 선형조절기는 외란에 대한 적응 및 안정도, 응답속도 측면에서 장점을 나타내었다. 향후 이 위성 모델 및 제어기를 사용하여 실제 운용시 예상되는 제어기의 결과를 확인할 수 있으며, 더 나아가 새로운 제어기의 개발 및 교육 등에 유용하게 사용될 수 있을 것이다.

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.

관성항법시스템은 항체의 자세, 속도 및 위치정보를 획득하기 위하여 폭넓게 사용되어 왔다. 그러나 관성센서는 매우 고가이며, 무겁고, 시간이 경과함에 따라 센서의 오차가 누적되어 발산하게 되는 단점이 있다. 한편 GPS를 이용한 항법시스템은 오차의 누적이 없고, 위성의 가시성만 확보된다면 빠르게 항체의 속도, 위치정보를 획득할 수 있으며, GPS 안테나 배열을 이용하면, 항체의 자세요소도 계산이 가능하다. 본 연구에서는 중저가 GPS 수신기의 안테나 배열을 사용하여 항체의 위치측위 정확도 및 자세 정확도 모두를 개선시키기 위한 방법을 연구하였다. 중저가형의 GPS 수신기 안테나 배열을 사용한 자세 결정 방법은 기준과 보조 안테나 사이의 상대적인 벡터에 초점을 맞추었다. 기준 안테나의 위치는 의사거리 측위로 한 단독 측위가 사용되었기 때문에 미터 수준으로 결정된다. 또한 항체의 측위 정확도 향상을 위해, 무선 인터넷을 이용하여 실시간 차분 보정을 실시하였으며, 중저가의 2주파 GPS 수신기를 사용하였다. 본 연구의 결과는 측위에서 센티미터 수준의 정확도를, 자세결정에서 도 수준의 정확도를 가지는 것으로 나타났다.

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.

This study was conducted to examine the effects of consumer evaluations on size recommendation services based on body information on consumer responses and the moderating effect of the level of information search. To analyze the research model, a total of 200 data were collected from August 18 to 24, 2022, targeting consumers who had experience with using size recommendation services based on body information. As a result of the research model analysis, it was confirmed that the compatibility, reliability, and convenience of the size recommendation services based on body information influenced attitude, which, in turn, influenced usage intention. In addition, In the case of the group subject to a low level of information search, the path through which compatibility and reliability influenced attitude was significant, but that of convenience was not. In the group featuring a high level of information search, the path through which reliability and convenience influenced attitude was significant, but that of compatibility was not. This study is meaningful in that it expanded research related to size recommendation services to the field of consumer behavior.
