This study suggests different improvement practices of adolescents' multicultural acceptability to compare the factors influencing multicultural acceptability with elementary and middle school students. The data used in this study come from the Korean Child and Youth Panel Study(KCYPS) of the National Youth Policy Institute(NYPI) comprising 4,092 responses from 5th grade elementary school students and 4th grade(middle school 2nd grade) of elementary school students. The study data were subjected to hierarchical regression analysis to give the following findings. First, Levels of Multicultural Acceptability were significantly different. Second, factors influencing multicultural acceptability for elementary school students and middle school students were different. Common factors were mother's education level, life's satisfaction, peer relationship, teacher relationship, and spirit of community. Factors for elementary school students's multicultural acceptability were subjective academic achievement, community awareness, experiences of cultural activity, and overseas visiting experiences. The factor for middle school students's multicultural acceptability was family/group travel experiences. Our findings highlight the importance of programs and education that are suitable for children's developmental level. Such peer group programs need to be offered for middle school students to achieve spirit of community and educational group program and various extracurricular activities to achieve community awareness and develop a spirit of community for elementary school students.

This study was performed to find the environmental factors of inquiry instruction perceived by secondary school science teacher. The instrument consisted of three domains such as teaching conditions, viewpoints of secondary school science teachers of environmental factors for inquiry instruction, and barrier and improve! rent factors of inquiry instruction. Teaching conditions between middle school and high school science teachers were not different significantly. Environmental factors of inquiry instruction of secondary school science teacher included five factors such as 'facilities and encouragement', 'amount of works and materials', 'teacher education and textbook', 'practice and knowledge' and 'perception of necessity and satisfaction'. And all factors except 'perception of necessity and satisfaction' were very low state for inquiry instruction. In the disturbant and improving factors, the critical factors were 'over students per class', 'textbook' and 'learning materials' for middle school science teachers, and 'over students per class', and 'entrance examination' for high school science teachers. Thus the development and diffusion of adequate inquiry learning materials may be helpful to practicing inquiry instruction as decrease of works and psychological charges, and it is needed to reorganize systematically and intensify pre- and in-service teacher education to practice inquiry instruction.

The variables studied in relation to adolescents' prosocial behaviors were grade, prosocial moral reasoning, empathy, self-esteem, parental prosocial behaviors, support and marital conflict, social economic status, peer prosocial behaviors and support, teacher support, school life satisfaction and achievement. The sample consisted of 837 seventh and tenth grade adolescents. Statistics and methods used for the data analysis were Cronbach's alpha, frequency, percentage, t-test, Pearson's correlation and multiple regression. Several major results were found from the analysis. First, female students had more prosocial behaviors than male students. Second, male and female students' prosocial behaviors showed positive correlations with grade, prosocial moral reasoning, empathy, self-esteem, parental and peer prosocial behaviors and support, teacher support and school life satisfaction. However, female students' prosocial behaviors had a negative correlation with parental marital conflict. Third, important variables predicting male and female students' prosocial behaviors were empathy, peer prosocial behaviors and parental prosocial behaviors. Important variables predicting male students' prosocial behaviors were teacher support and prosocial moral reasoning. On the other hand, the important variable predicting female students' prosocial behaviors was self-esteem.

Objectives: Health-related quality of life (HRQoL) is an important outcome for middle school students. This study was designed to illustrate the effect of social support and class cohesiveness associated on HRQoL. Methods: The subjects comprised 516 students from three middle schools in Daegu, South Korea that responded to a self-administered questionnaire in February 2014. The purposes of the questionnaire were explained to the subjects. Results: The total mean of HRQoL was $81.1{\pm}15.3$. Social functioning showed the highest score of $87.1{\pm}15.3$ and emotional functioning showed the lowest score of $73.8{\pm}21.5$. Teacher support (B=3.185, p=0.001) had a significant effect on the physical health summary scores. Class cohesiveness (B=2.237, p=0.022), friendships (B=5.102, p<0.001) and teacher support (B=2.498, p=0.006) had a significant effect on the psychosocial health summary scores. Finally, class cohesiveness (B=2.137, p=0.016), friendships (B=4.133, p<0.001) and teacher support (B=2.670, p=0.001) had a significant effect on the overall scores. Conclusion: The results of this study provide a basis for the development of strategies to improve health-related quality of life for middle school students, namely that relevant programs should be based on the improvement of social support and class cohesiveness.

The purpose of this study was to survey science teachers, perception and attitudes on disposal of school laboratory waste water and materials. To fulfill this aim, a questionnaire was administered to 244 secondary school science teachers. The result of this study revealed that there was no large disparity in the degree of understanding of laboratory waste disposal and the laboratory waste water treatment, and in secondary science teachers' perception and practicing attitude on the environment. While science teachers had deep understanding of laboratory waste disposal and its influence on environmental pollution, they expressed less positive attitude toward the actual disposal of waste materials and waste water, and participation in teacher training. Therefore, it is necessary to provide standards of systematized disposal methods and proper disposal facilities in middle and high school laboratories, as well as to investigate teachers' needs before providing teacher training program.
