Attitude control modeling and simulation (M&S) can be extensively applied in overall development process, from simple algorithm design to on-board software verification. This paper introduces CMG-based attitude control M&S software, which consists of 6-DOF modeling (CMG and space environments modeling), and attitude control algorithm. The M&S software is divided into three modules, from an inner CMG motor control module to an outer earth observation mission module. While an application of this developed software is currently limited to the initial-phase attitude controller development, its application area can be extended to the later-phases by considering sophisticated model information in future.

This study was surveyed the knowledge and attitude toward the elderly in dental personnels, who play an important role in oral health of the elderly in the aging society, In order to arrange the basic data that is conducive to development in the mouth care of the elderly, the research was conducted from January 7 to February 14, 2008, targeting 270 dental personnels in Daejeon & Chungnam area, who are in charge of oral duties in the current clinic. As a result of analyzing so that questionnaire can be prepared with the self-administered questionnaire, the following results were obtained 1. The knowledge level on the elderly in dental hygienist was 13.47 marks out of 25-mark perfection. There was no difference in knowledge depending on job category and volunteer-work activity experience, And, there was no difference even depending on physical & physiological sphere, psychological sphere, and family & social sphere. 2. The attitude level toward the elderly in dental hygienist was 91.63 marks out of 150-mark perfection. Dental hygienist showed positive attitude in personality characteristic, emotional characteristic, and self-management ability by sphere, and showed statistically significant difference (p=0.011). 3. In case of having volunteer-work activity experience, the attitude level toward the elderly was 92.57 marks out of 150-mark perfection, A case of having volunteer-work activity experience showed positive tendency in emotional characteristic, self-management ability, and judgement-ability characteristic by sphere, And, the attitude toward family relation was indicated to be negative tendency, thus there was statistical significance(p=0.022). 4. As for the correlation between knowledge and attitude toward the elderly, dental hygienist was indicated to have high interest in the volunteer-work experience, the elderly education experience, and the elderly problem(r=0. 444). The knowledge and attitude toward the elderly had slightly positive correlation(r=0.155). Dental hygienists are being required gradually as the primary staff for the elderly people's dental care in the aging society. A continuous education is needed so that dental hygienists can have positive sight in understanding, knowledge, and attitude. And, the development in a mouth care program for the elderly in line with it is considered to be necessary.

Family environment plays a significant role in adolescent development. Multicultural adolescents in Korea are brought up in a distinctive family environment, where they get to experience two different cultures within their families. Thus, it is important to examine how internal characteristics of the family environment in multicultural families and interactions between family members influence adolescents. The aim of the current study was to examine structural relationships among Southeast Asian mothers' and Korean fathers' bilingual socialization, adolescents' attitude toward mothers' native culture, and mother-adolescent relationship satisfaction. Specifically, the following two questions were addressed in this study: 1) Does bilingual socialization of each parent affect adolescents' attitude toward mothers' native culture? 2) Does children's attitude toward mothers' native culture affect mother-adolescent relationship satisfaction? To answer these questions, the survey data from the '2012 Nationwide Survey of Multicultural Families' was analysed, using SEM. The sample consisted of 318 multicultural adolescents (aged 9-17) living with Korean fathers and immigrant mothers from Southeast Asia. The main findings were as follows. First, Korean fathers' bilingual socialization had a positive effect on immigrant mothers' bilingual socialization. The path from Korean fathers' bilingual socialization to adolescents' attitude toward mothers' native culture was significantly mediated by immigrant mothers' bilingual socialization. Second, adolescents' attitude toward mothers' native culture had a positive effect on mother-adolescent relationship satisfaction. Results suggest that Korean fathers' bilingual socialization is an important factor for bilingual socialization of multicultural adolescents. It is also worth noting that each parent's bilingual socialization helps multicultural adolescents to form a positive identity as a member of multicultural families.

Leadership development corresponds to the focus on the individual's success and competitiveness strategy. This is the optimal direction of the organization of attitude development because it covers two aspects of the student's personality development, professionally-oriented and self-centric. The aim of the study is to identify and compare the leadership level in second-and fourth-year students to see dynamics of development and implementation of the leadership phenomenon in the professional and personal making up of future specialists. Based on the theoretical analysis of the issue, the authors developed an objective and subjective diagnostic model for leadership skills. In this study, data of the objective diagnostic technique are the key. Subjective diagnostic technique for leadership skills provides insights for problem interpretation. At the level of the first group of respondents, the average Leadership Skills Level of the second-year students was quite low and was found within the medium level. The second group of respondents consisting of the fourth-year students showed a slight but effective improvement. The Leadership Skills of this group were found at a sufficient level. Positive dynamics was revealed for all criteria of leadership skills as a result of applying objective diagnostic methods: decreased percentage of students with negative and relatively low markers of Leadership Skills Level and corresponding increase in percentage of applicants with positive markers of Leadership Skills Level. Further research can be organized in the direction of identifying and developing successful universal and professionally-oriented tactics for leadership development in students as part of attitude development.

The purpose of the study is to investigate the effects of eating disorder belief and sociocultural attitudes towards appearance on female high school students' eating attitude. Questionnaires regarding eating disorder belief, sociocultural attitudes towards appearance, and eating attitude were administered to 900 1st and 2nd grade female high school students in Gyeonggi Province. Finally 875 questionnaires were collected and statistically analyzed through Cronbach's ${\alpha}$, factor analysis, Pearson's correlation analysis, and hierarchical multiple regression. The main results of the study were as follows: 1) Eating disorder belief, sociocultural attitudes towards appearance, and eating attitude revealed a positive correlation. 2) While control over eating, weight/shape as a means to acceptance, internalization, and awareness were significant predictors of drive for thinness, control over eating, internalization, and weight/shape as a means to acceptance were significant predictors of bulimia. 3) Internalization had a moderating effect on the relationship between eating disorder belief and eating attitude (drive for thinness, bulimia).

Satellite attitude-control actuators are equipped with a reaction wheel for three-axis attitude control. The reaction wheel rotates a motor inside the actuator to generate torque in the vector direction. When using the reaction wheel, there are restrictions on the torque values generated as the motor rotates. The torque value of the reaction wheels mounted on small satellites is approximately 10 mNm, and high values are not used. Therefore, three-axis attitude control of a small satellite is possible using a reaction wheel, but this method is not suitable for missions that require rapid attitude control at a specific time. As a technology to overcome the small torque value of the reaction wheel, the control moment gyro (CMG) is currently in wide use as a rapid attitude-control actuator in space satellites. The CMG has an internal gimbal mounted at a right angle to the rotation motor and generates a large torque value. In general, when the gimbal operates, a torque value approximately 100 times greater is generated, making it suitable for rapid posture maneuvering. Currently, we are developing a technology for mounting a controlled moment gyro on a small satellite, and here we share the development status of an 800 mNm CMG.

The present paper attempts to investigate the factors which may affect the attitude toward Oriental Medicine among the university students in Korea and China. The research on determining factors that may influence the attitude toward the Oriental Medicine can provide the answers for the question how the traditional things can acquire their present position and make a development in modern society. The East Asian countries such as Korea and China have promoted the western-style changes and development, thinking that modernization means the westernization. Given this, the research on the attitude toward Oriental Medicine can be a good case study that shows how tradition sustains its place and develops. The present study makes two hypotheses in order to analyze the factors which make the influence on the attitude toward the Oriental Medicine: Hypothesis there will be no significant difference between the socio-demographic variables and attitude toward Oriental Medicine. Hypothesis there will be significant differences between traditionalism, modernity, nationalism, and attitude toward Oriental Medicine. The statistical results show that hypothesis 1 was confirmed in the case of the gender of the participants, whereas it was not confirmed in the case of the birthplace, economic status, and nationality. And hypothesis 2 was not confirmed in the relations between nationalism and modernity and the attitude toward Oriental Medicine, whereas it was confirmed in the relations between traditionalism and the traditional medical concept and attitude toward Oriental Medicine.
