The purpose of this study is to verify learning components to be taught in each grade of middle schools, to propose hierarchical structures on algorithm content, and to resolve overlapping across related subjects. In order to verify learning components, four criteria were proposed. To evaluate practical application, they were implemented into The Proposal of Curriculum Revision on Computer Education in Middle School on MPE website. It was found that there was content overlapping between 'problem solving methods and procedures' in the middle school Informatics Curriculum and 'regulation and problem solving' in the Elementary Mathematics Curriculum. So it is needed to find a way to differentiate the contents of 'problem solving methods and procedures' from the other related subjects.

Objective: The aim of this study was to examine the mediated effect of teacher-infant relationships between teacher efficacy and infant's adjustment to child care centers. Methods: A total of 137 child care teachers that lived in Gwangju and Jeollanamdo participated in this study. They were asked to answer two survey questionnaires for two infants. The data were analyzed using analysis of frequency, Pearson's correlation coefficient, and hierarchical multiple regression analysis. Results: The main results are as follows. First, teacher-infant relationships partially mediated the relationship between teacher efficacy and two sub-factors (prosocial behavior and day work adjustment) of adjustment in child care centers. Unlikely as it was, several sub-factors such as positive emotion, peer adaptation, and self-strength were fully mediated by teacher-infant relationships. Conclusion: The present study suggests that it is necessary to improve teacher-infant relationships with teacher efficacy in order to improve infants' adaptation to daycare. In addition, it should be understood that the structural relationship of the influence factors is different depending on the sub-factors of the child care adjustment.

This research is focused on the influence of internalization problem and attachment to parents on the adjustment to school life, as well as on the attachment to parents as moderators in the influence of the process of internalization problem on the adjustment to school life. To verify the hypothesis, a survey research method was applied using stratified cluster sampling method, and focusing on middle school students in Seoul. Eleven schools were selected randomly from each of the eleven District Offices of Education in Seoul, and data were collected from 1,200 students. The data were analyzed by using the T-test and hierarchical regression methods, and the results are as follows. First, the internalization problem has negatively affected the adjustment to school life. Secondly, the moderators of the attachment to parents in the adjustment to school life were investigated. Through the above mentioned analysis, it can be deducted that, intervention with internalization problem is required in order to promote the adjustment to school life, and the importance of the attachment to parents should be addressed in the intervention for improving adjustment to school life.

This study aims to analyze the priority of regional climate change policy utilizing AHP (analytic hierarchy process) at the area of Metropolitan City of Incheon. It derives four factors at first hierarchical level, at which level the analysis of pair-wise comparison indicates that industrial sector, energy sector, climate change response, and green culture policy are considered important in that order. It also ends up with sixteen factors at second level. The result of comparison analysis between all factors reveals that investment promotion in green technology R&D is considered the most significant factor of all, followed by establishment of green enterprise support system, electricity-efficiency enhancement support project and build-up of green culture policy governance. The result implies that diverse promotional policies have to incorporate business, institutional, and cultural aspects for sustainable climate change policy of regions. The contribution of this study is that it highlights the need to include regional characteristics in deciding priority among policy options for them to be effective.

Purpose: This study was conducted in order to determine the extent of ego integrity and to confirm the association between the sense of ego integrity and integrated loneliness, social support, and social activities. Methods: For this study, 146 elderly people participated. The data was analyzed with SPSS/WIN 21.0, using descriptive statistics, t-test, ANOVA, correlation analysis, and hierarchical regression analysis. Results: In regards to differences between ego integrity according to general characteristics of subjects, there was a statistically significant difference in education (F=4.13, p=.007). In elderly living alone, ego integrity was significantly positive correlated with social support and social activities, but negative correlated with loneliness. These variables explained 43.2% of the sense of ego integrity. Conclusion: The study suggested that nursing programs and social activity programs designed to aid the elderly living alone must focus on reducing loneliness, as well as increasing social support and social activities, while taking education into consideration. Also, these programs should strive to build social support systems.

Purpose: The purpose of this study was to identify the relationships among emotional labor, empowerment, job burnout, and turnover intention. Methods: The design of this study was a cross-sectional descriptive study. The subjects of this study were 358 nurses working for over 6 months in Seoul and Gyeonggi-do. The data were collected from 4th to 30th of September, 2009 through one-to-one interviews. Survey data were analyzed using t-test, one-way ANOVA, Pearson's correlation coefficient, and hierarchical regression. Results: We find the positive correlation of turnover intention with emotional labor and with job burnout, but the negative correlation of empowerment with job burnout and with turnover intention. The nurses' turnover intention scores were relatively low with 1.30. Job burnout, shift work, and frequency of turnover were predictors of turnover intention. The most powerful predictor variable was job burnout (${\beta}$=.420, p<.001). We find that emotional labor and empowerment as determinants of turnover intention are not significant. Conclusion: These results suggest that manager should consider shift work of nurses and job burnout in order to manage nurse organization and resource effectively.

Purpose: As the importance of software has been emphasized recently, the size of the software market is continuously expanding. The development of the software market is being adversely affected by software piracy. In this study, we try to classify countries around the world based on the macro environmental factors, which influence software piracy. We also try to identify the differences in software piracy for each classified type. Design/methodology/approach: The data-driven approach is used in this study. From the BSA, the World Bank, and the OECD, we collect data from 1990 to 2015 for 127 environmental variables of 225 countries. Cronbach's ${\alpha}$ analysis, item-to-total correlation analysis, and exploratory factor analysis derive 15 constructs from the data. We apply two-step approach to cluster analysis. The number of clusters is determined to be 5 by hierarchical cluster analysis at the first step, and the countries are classified by the K-means clustering at the second step. We conduct ANOVA and MANOVA in order to verify the differences of the environmental factors and software piracy among derived clusters. Findings: The five clusters are identified as underdeveloped countries, developing countries, developed countries, world powers, and developing country with large market. There are statistically significant differences in the environmental factors among the clusters. In addition, there are statistically significant differences in software piracy rate, pirated value, and legal software sales among the clusters.
