The purpose of this study is to investigate the effects of the educational context variables on students' science achievement and interest in TIMSS 2015. TIMSS 2015 science data and questionnaire results were used to fit the Hierarchical Linear Model (HLM) in this study. According to the results, books at home, parents' level of education, and students' views on science lessons have significant influence on science achievement of above-high level 4th-grade students, and books at home on below-intermediate level 4th-grade students. Books at home, students' views on science lessons, and school composition by student economic background have significant influence on science achievement of above-high level 8th-grade students, and books at home and students' views on science lessons on science achievement of below-Intermediate level 8th-grade students. In all grade levels, books at home, and students' views on science lessons have significant influence on science achievement and interest. Discussed in the conclusion are ways to improve science teaching and learning including offering systematic reading programs for all students, reinforcement of student-participation in science classes, connecting science hands-on activities with science concepts for below-Intermediate level elementary students, and so on.

Due to the increasing concerns with the North Korean defectors, the researches have been increased. When it is compared with other areas, the researches about the North Korean defectors are rare. The sample size of this study is 164, which makes it possible to do statistical inferences. As statistical methods, t-test, ANOVA and hierarchical multiple regressions are used. This study examines the effect of the adjustment stress and the social support on the depressive symptoms. Demographic factors such as gender, age and education are controlled. The context factors-the period of the stay in the third place, the period of residence and the existence of the education in Korea- are used as control variables. The research results show that the level of social participation of the women is higher than that of men. Also, there are differences of the functional social support by the age group. The research result indicates the education of South Korea is an important factor to reduce the depressive symptoms. The research result also shows that the jobless is an important stressor. Among structural social support, the member of religious or social group is an important factor for reducing depressive symptoms. Among functional social support, the emotional social support is an important factor of adaptation, but the effect of instrumental social support is the opposite. Therefore, the adequacy of social support in a specific situation must be considered.

This article is the critical review of the methods and assumptions with which the Korean archaeologists have tried to approach to the Bronze age society. It was not until the 1980s' that there had been any attempt to define the relevant units for the study of past societies. Before the archaeological records of megalithic builders in the Bronze age began to be analyzed to find out the general traits of chiefdom society, Korean archaeologists had described the variations in the cultural, rather than the social, entities. From the 1990s' , some scholars have attempted to reconstruct the scale and organization of the social groups and explain the growth of polities in evolutionary view, analyzing the hierarchical distributions of settlement data. In the concluding remarks of the review, I would like to indicate the some problems in the conceptualization of the material culture patterning in the regional and/or inter-regional level. First, the conceptual problem which appeared when the Bronze archaeologists define the distribution of artifact assemblages, composed of the specific artifact traits , beyond the instrumental categories that are efficient for the establishments of regional chronologies. It is evidently erroneous conceptualization that we define the artifact assemblages as the socio-cultual entities which came into being in specific time and place, geographically expanded, and finally disappeared based on the view of essentialism. Second, the interpretative problems about wide distributions of certain bronze artifacts must be indicated. I would like to suggest that the wide distributions of the specific bronze dagger or mirror types should be explained not by the cultural area concept related to the ethnicity assumptions, but by the world system or the inter-regional interaction models.

The purpose of this study is to compare and analyze the effects of the educational context variables on 8th-grade science achievement of 5 top performing countries(Korea, Singapore, Taiwan, Hong Kong and Japan) in TIMSS 2015. TIMSS 2015 science data and questionnaire results were used for fitting Hierarchical Linear Model (HLM) in this study. According to the results, such student-level variables as home resources for learning, students' interest in science learning, valuing science, Students' Educational Expectations gave significant influence on the science achievement of Korean students. School-level variables including Student Economic Background, and School Emphasis on Academic Success gave significant influence on the science achievement of Korean students. Comparing 5 countries, home resources for learning, students' interest in science learning, Students' Educational Expectations gave significant influence on the science achievement in all 5 countries. At the school level, Student Economic Background is statistically significant in explaining students' science achievement gap in all countries except Japan, and Teaching Limited by Student Needs gave significant influence on the science achievement in all countries except Korea. Discussed in the conclusion are ways to improve middle-school science teaching and learning including reducing the education divide among socioeconomic status, teaching innovation for competency education, inquiry and reinforcement of lab activities in science classes, and so on.

This article addresses the 2nd Korean consensus conference on cloning that was held by the Korean National commission for UNESCO in 1999. Though previous perspectives recognized the conference as a new citizen's participatory institution. they do not consider that it contains the ideal of deliberative democracy. This article notes that the citizens participated directly and handled the important social agenda through debate in the consensus conference. The consensus conference is another democratic form derived from preference aggregating democracy in the sense that it basically depends on public judgement of the citizens. This consensus conference has the historical meaning because it is in fact the first experiment of deliberative democracy in Korea. 1) We examine the theoretical foundations of consensus conference. They are social constructionism of science, the tradition of societal debate, and deliberative democracy. 2) We explore what deliberative democracy is. It is different from aggregating preference democracy in the sense that it depends on public judgement rather than private preferences. 3) We investigate the features and meaning of deliberative democracy which has experiment on the conference. In the Consensus Conference it was observed that citizens changed their preferences and went forward to developing their view of community as a result of the process of deliberation. It can be said to confirm the significance of deliberative democracy. However, it is simultaneously an opportunity to clarify some problems of deliberative democracy. First of all, it shows that there were hierarchies within the citizens' panel as well as between the citizens' and the specialists' panels. Secondly, there are difficulties in expressing the value of life in argument or discourse. Also, we need the institutional efforts concerning future generations and nonhuman beings in the respect that cloning relates to them.

This study attempts to analyze the effects of distance-accessibility to the complex shopping mall of 'Lotte Mall-Suwon', located at the old central and catchment district of the Suwon station in the Province of Gyeonngi, on the prices of its neighboring apartments within the Gwonseon-gu of Suwon City by using the hierarchical and linear-difference in difference regression method. The results of the analysis are as follows. First, before construction the effects of distance-accessibility show the U-shaped pattern, suggesting that the negative external effects of noise and traffic congestion around the Suwon Station affected the prices of its neighboring apartments within the Gwonseon-gu of Suwon City. Second, the effects of distance-accessibility at different times, such as the construction period and after the opening, are statistically significant only in the latter, indicating the reverse U-shaped pattern unlike before the opening. This means that after the opening of the complex shopping mall its external effects as a leisure and convenience space have a positive effect on the prices of its neighboring apartments within the Gwonseon-gu of Suwon City. Third, the effects of distance-accessibility is at an inflection point around 1.6-1.7 kilometers, which means that the U-shaped distance-decay pattern before construction, while the reverse U-shaped pattern is shown after the opening of opening. The latter implies that apartments that are very close to the mall within the Gwonseon-gu of Suwon City enjoy relatively small positive externalities. Therefore, they are exposed to some negative external effects of noise and traffic congestion, but apartments with some distance apart within the Gwonseon-gu of Suwon City maximize those positive externalities. These results suggest that the effects to distance-accessibility are different from location to location.

In this paper, I studied the relation between narrative construction (especially focusing on motif) and humor mechanism based on binge watching environment. Several motif theories such as B. Tomachevski, Horst and Ingrid Dämmrich and S. Chatman are used as a basic study method in chapter II. In popular sitcom , sometimes kernels(according to S. Chatman's term) in certain season's story are changed into satellites(according to S. Chatman's term) in other season's stories. The motif of Ross and Rachel's conflict is a representative example for this switching process. Especially on binge watching environment, as the interval length is much more shortened, viewers tend to reflect their own emotional memory into characters less strongly than segment watching environment. As a result, the possibility 'heavy' stories such as seperation are quickly changed into 'light' humorous matters is increased. This kind of hierarchy variation of repeated motif make the viewers laugh, because they can feel sudden liberating energy by eliminating psychological pressure. It means the characteristics of sitcom's humor on binge watching environment can also be explained by the theory of 'laugh as a eliminating tension', which I. Kant representatively said.

Previous findings on Organizational Citizenship Behaviors is a useful index for effectiveness of the organization. Also, it is a factor that explains the relation between its member's attitude and behavior as organizational commitment had been stabilized. Since autonomy and rapidity has become more important in increasing the efficiency of the organization, this means Organizational Citizenship Behaviors has become important in it. Organizational Citizenship Behaviors of the members occurs only when discretion and autonomy are given to its members. Therefore, this study aimed at measuring the effects of police officer's personal dispositions on organizational citizenship behaviors, exploring the moderation effect of organization culture, and providing the basis with implications to promote the Organizational Citizenship Behaviors in the police Organization. By reviewing previous finding, Police Officer's Personal Dispositions were selected as independent variables, Organizational Citizenship Behaviors was selected as dependent variable. and Organizational Culture was selected as moderation variable. The result of analysis showed that The belief & The Norm influenced in Organizational Citizenship Behaviors(positive), and The Value in Organizational Citizenship Behaviors(negative). And The moderation effect was tested: The Value${\rightarrow}$Hierarchical Culture${\rightarrow}$Organizational Citizenship Behaviors(negative), The belief${\rightarrow}$Rational Culture${\rightarrow}$Organizational Citizenship Behaviors(negative)

This study was conducted to investigate the effects of implementation of the healthcare accreditation system on patient safety, quality of medical care, organization culture and management performance of convalescent hospitals. Ten hospitals were selected at random from among 36 convalescent hospitals in Daegu that had obtained accreditation until September 2015. To accomplish this, hospital staff were surveyed from 15 February to 25 March, 2016 using a questionnaire with 253 objects. We investigated how the healthcare accreditation system has influenced patient safety, service quality, organization culture and performance of hospital management. The change in the treatment support system showed the highest score of 3.93 among quality change and medical service items, while that of personnel source culture showed the highest score of 3.78 points among organization culture items, and that of internal process view, study and growth view showed the highest score of 3.71 among management performance items. Multiple regression analysis revealed that factors positively changing hospital management performance were nurses, employees and managers, basic value systems, organization culture, personnel source culture, open system culture, hierarchical culture, and production oriented culture. The quality of patient safety and medical care was positively influenced by changes in the quality of convalescent hospitals after implementation of the healthcare accreditation system. However, among the four types of organizational culture, the financial perspective was relatively low compared to other perspectives.

The purpose of this study is to explore the perception of the observation and nomination system for the identification of the gifted and to find out the importance and practice level perceived by the gifted education teachers using the concept mapping approach. For this, twelve gifted education teachers brainstormed and gathered ideas for the ideal ways of observation and nomination system and the gathered statements were solicited. Multidimensional scaling and hierarchical cluster analysis were also used. In addition, 112 gifted education teachers rated the importance of and the practice level for the suggested ideas of observation and nomination system. Results were as follows: First, 36 statements were solicited and as a result of concept mapping the suggested observation and nomination system were categorized as 'attainment of professionality', 'attainment of administrative support', 'attainment of fairness', and 'considering points for recommendation.' Second, there were significant differences between the perceived importance levels and the practice levels. Based on the results, imlications of the study were discussed in depth.
