The purpose of this study was to design a development frame for multicultural science program and develop a corresponding program using the frame. This study organized a development frame to design a multicultural science education program based on the culturally responsive teaching theory. This development frame consisted of the elements of purpose, teaching examples, teaching and learning methods, and assessment. This program consisted of the guideline for class teaching courses, reading materials, student worksheet, and teachers' reference materials. Based on this development frame, a multicultural science education program was developed, which was comprised of seven activities for elementary and middle school students. Each activity of the program included the concept and inquiry related to science education. In particular, by connecting the concept of science with the cultural characteristics of various countries, the activity made students aware of cultural diversity and the commonness of science principles. Compared to other subjects, the science education field has not actively undertaken studies on multicultural education. In term of dealing with universal principles, science education is suitable for making students aware of commonness. Accordingly, this gives rise to the need to draw cultural characteristics based on basic studies such as the analysis of science textbooks in various countries and develop culturally responsive programs utilizing the outcomes.

The objective of this research is to review the ergonomic keyboard developed to prevent musculo-skeletal disorders from being occurred during keyboard work. It was studied by comparing it with the traditional keyboard after analyzing and comparing the typing performance and work advantages both the two keyboards. Twelve male subjects with no history of musculo-skeletal disorders participated in the experiment. The quantitative data such as typing speed, accuracy, performance time, and the number of typing errors were obtained from the HTT software that was adjusted for this experiment. RULA worksheet and the degrees of extension and ulnar deviation on right and left wrist were used to analyze the upper body postures. The experiment results showed that the typing performance of the ergonomic keyboard decreased a little, but no significant difference statistically, compared with that of the traditional keyboard. On the work posture, the ulnar deviation during typing decreased in case of the ergonomic keyboard. But, the wrist extension was increased unexpectedly. Therefore, it can be regarded as these results occur due to the shape of wrist rest and the overall height of keyboard on a table. As a result, the reconsideration and redesign on the ergonomic keyboard are requested.

South Korean society faces various difficulties since it has not prepared for the stable settlement of families. Therefore, it is necessary to initiate marital education for the settlement of multi-cultural families in a healthy and democratic way. This researcher has developed a marital education program for multi-cultural families. To reflect the special characteristics, this work required the investigation of multi-cultural families in Gyeongsangbuk-do. The purpose of this work is to improve conjugal relations among multi-cultural families in a formative period of family relations to help those families to settle down early. The program consisted of four steps and 12 sessions. It featured an increase in application flexibility to an actual site by session, and includes a worksheet applicable to an actual site to understand the absence of communication and cultural differences in multi-cultural families during a formative period of family relations. In so doing, it was designed to easily perform nonverbal education.

In this study, the relationships among learners' cognitive variables, motivational variables, and conceptual understandings in learning with analogy were investigated. The instruments regarding analogical reasoning ability, field dependence-independence, mental capacity, and logical thinking ability were administered. Some subtests (self-efficacy, expectancy, self-concept of ability, and value) of the Patterns of Adaptive Learning Survey were administered. After students learned with a worksheet that included analogy, a conception test regarding 'stoichiometry that included limiting reagent' was also administered. It was found that learners' conceptual understandings were significantly correlated with the logical thinking ability and the field dependence-independence among the cognitive variables, and the self-efficacy and the self-concept of ability among the motivational variables. The multiple regression analysis of the cognitive variables on conceptual understandings revealed that the logical thinking ability was the most significant predictor. The field dependence-independence also had predictive power. In the analysis of the motivational variables, the self concept of ability was the only significant predictor.
