The purpose of this study was to evaluate the effects of STS Programs on science-related attitude of junior high school students. For this study, samples of 198 students who are in grade 8 were selected. The eight STS Programs were used in this study. One group pretest-posttest design was used in this study as an experimental design. The TOSRA was used in this study as the science-related attitude evaluation instrument. The major results of this study are as followings: 1. The effects of STS programs about the junior high school students' science-related attitude indicated that there were no statistically significant differences between pretest and posttest. 2. Total students were classified as high(above about mean) or low (bellow about mean) on the basis of science-related attitude pretest scores. The low level students have improved from using of STS programs in teaching science on science-related attitude scores. The high level students have dropped from using of STS programs in teaching science on science-related attitude scores.

Purpose: This study was to identify the relationship between sexual attitude, sexual identity, sexual permissiveness in girls in junior high school, Method: The participants were 587 female students in Chungnam Province. Data were collected by questionnaire surveys using convenience sampling. The instruments were the Sexual Attitude Scale by Kim (1997), the Sexual Identity Scale by Jung (1990), and the Sexual Permissiveness Scale developed by Reiss (1964). Data were analyzed by the SPSS 11.0 program. using descriptive statistics, Pearson correlation coefficients, t-test, ANOVA and Tukey's multiple comparison. Results: The relationship between sexual attitude and sexual permissiveness had a positive correlation (r=.440, p-0.000). Sexual identity was positively correlated (r=.180, p=.036; r=.222, p=.014) with both sexual attitude and sexual permissiveness, but maleness was the only positive correlation (r=.258, p=.014) with sexual permissiveness, no sexual specialization was the only characteristic that had a positive correlation (r=.188, p=.046) with sexual attitude. Conclusion: These results suggest assessment of these factors and treatment fitted to individual needs are important for correct sexual culture. There should be repeated research on various population groups. Moreover, it is considered necessary to carry out factor-related theoretical researches on several variables related to sex through multilateral literature reviews.

This study classifies vanity into groups, analyzes age differences and categorizes price attitudes toward apparel products. Questionnaires were administered to 461 college students living in Daegu City and Kyungbok province. Data were collected using frequency, factor analysis, cluster analysis, correlation analysis, regression analysis, ANOVA, Duncan-test, and t-test. The findings were as follows. College student vanity was classified into three groups of appearance/ achievement pride, low vanity, and appearance/achievement concern. Vanity showed a significant correlation with sub-variables of age difference and price attitude towards apparel products. Appearance pride and achievement concern (sub-variables of vanity) had a significant effect on the conspicuous of price attitude toward apparel products. Appearance pride and Appearance concern (sub-variables of vanity) had a significant effect on information of price attitude toward apparel products. Gender of college students showed a distinction insub-variables of vanity factors such as appearance concern and price attitude toward apparel products such as information, quality, and using coupons. Male students were distinct in look and health as well as age differences by group; female students were distinct in age perception differences (a sub-variable of age difference). Both male and female students showed differences in conspicuousness (a sub-variable of price attitude) toward apparel products by group.

Orbit-raising is an important step to place spacecraft from parking orbits into working orbits. Attitude control system design is crucial in the success of orbit-raising. Several text books have discussed this design and focused mainly on the traditional methods based on single-input single-output (SISO) transfer function models. These models are not good representations for many orbit-raising control systems which have multiple thrusters and each thruster has impact on the attitude defined by all outputs. Only one published article is known to use a more suitable multi-input multi-output (MIMO) Euler angle model in spacecraft orbit-raising attitude control system design. In this paper, a quaternion based MIMO model for the orbit-raising attitude control system design is proposed. The advantages of using quaternion based model for orbit-raising control system designs are (a) there is no need for mathematical transformations because the attitude measurements are normally given by quaternion, (b) quaternion based model does not depend on rotational sequences, which reduces the chance of human errors, and (c) the singular point of reduced quaternion model is the farthest from the operational point where linearization is performed. We will show that performance of quaternion model based design will be as good as the performance of Euler angle model based design for orbit-raising problem.

This paper present an attitude control using quaternions as feedback attitude errors. The Euler's eigenaxis rotation provides the shortest angular path between two attitudes. This eigenaxis rotation can be achieved by using quaternions since quaternions are related with the eigenaxis. The suggested controller uses error quaternions and body angular rates and generates a decoupling control torque that counteracts the natural gyroscopic coupling torque. The momentum dumping strategy using the earth magnetic field is also applied in this paper to unload the angular momentum of the reaction wheels used in the attitude control.

Objectives: The purpose of this study is to empirically verify the difference between traditional gender role attitude and realistic dual earner attitude. Most preceding studies analyzed gender role attitude by summated rating scale while few studies have been conducted on the difference between traditional gender role attitude and dual earner attitude. Method: By using the 9th Korea Welfare Panel Data (year 2014), this study extracted households of married couples and with children in working age (18 through 64 years of age) who are the main subjects in work-family relationship. First, this study classified traditional group and modern group in their gender role attitude and passive group and active group in their dual earner attitude and by crossing these attitudes, drew out 4 gender role/dual earner attitudes. For analysis, this study investigated frequency of attitude types through descriptive statistics. By conducting ANOVA, study verified if there are significant differences in the satisfaction with family relationship depending on the types of gender role/dual earner attitudes. Lastly, study examined the effect of socio-economic status and demographic characteristics on the types of gender role/dual earner attitudes by conducting multi-nominal logistic regression analysis. Results: As the result of analysis, first, half of respondents belonged to 'equal-role-oriented type' who has modern gender role attitude and active dual earner attitude. However, there were not a few 'dual-earner-avoiding type' who has modern gender role attitude but passive dual earner attitude and 'incongruous attitude type' who has traditional gender role attitude but active dual earner attitude. Next, 'incongruous attitude type' had significantly low level of satisfaction with overall family life, relationship with spouse and relationship with children than other attitude types. Lastly, those whose incomes belong to poor strata, those who are high school graduates and lower, males and those who are over the age of 60 had significantly higher probability of belonging to 'incongruous attitude type.' Conclusion: The results of analysis demonstrate that the difference between gender role attitude and dual earner attitude is an important matter and since 'incongruous attitude type' exhibits low level of satisfaction with family relationship, scrupulous policy approaches are required for those who have high possibility of belonging to 'incongruous attitude type.'
