In the studies on residential move, there has been tendency of dichotomy where short distance moves are largely caused by housing to adjust to changes in households while long distance moves are induced by shift in labor market. However, some empirical studies have proven that residential move is so complex process that the simple dichotomy should be elaborated. In this sense, the present study seeks to identify compounded course of residential move in Korea. In determining migration history, families with younger householders, renters, householders with higher educational attainment and smaller households show a higher probability to move. In case of mobility, women were more prone to move compared to man. Women compared to man, older age augmented the probability to own a house after migration. Families with householders following an occupation of sales and technical service showed lowest tendency to own houses while it marked the highest in the group of professionals. Higher land price of a region was negatively related to owning houses after migration. The present study revealed that factors in macro level as well as micro level significantly affect the move of individuals with varying effects in accordance with migration history.

The purpose of this study is to analyze the implications of the case of France, which has already implemented the social integration policy with the interest of the social integration of migrants in advance of Korea. First, we analyzed the system and system of social integration policy in France. Second, we analyzed the social integration policy promotion system in France, and examined the ministries and the agencies that direct the integration policies of the migrants. Third, the implications for the integration policy of Korean immigrants were derived through the above analysis. As a result, France was promoting a consistent social integration policy at the level of the central government, and all members of the society participated in the social integration program. It also encouraged participation in the program in conjunction with social integration programs. Based on this, we concluded that the social integration policy of our country should be modified somewhat. First, it is necessary to pursue the unity of policy by uniting the ministries that can manage migrant social integration policy in our country. Second, the main target of the social integration policy of our country should include not only immigrants who migrated from abroad but also Koreans. Third, Korea should encourage migrants to participate more in social integration programs and at the same time increase their participation rate by disadvantage of staying.

The purpose of this study is to examine the cases of social integration in immigrants in the Netherlands and to clarify the implications for Korea. The Netherlands is a country that implements social integration policies targeting foreign immigrants. We are preemptively implementing social integration policies for foreigners ahead of us. In this study, first of all, the literature on social integration for the immigrants in the Netherlands and the consultation on the experts were sought and the implications for the Dutch government 's social integration policy were sought. In addition, policy implications were derived based on the results of Dutch case analysis. First, the social integration program of the Dutch government mandated social integration programs for migrants, and the costs were also monetized, encouraging social integration. Also, when participation in the social integration program is passive, it imposes sanctions on migrants and emphasizes the responsibility of individual migrants. In addition, the Ministry of Internal Affairs is the control tower of the government's promotion system, and it has a platform for the unity of social integration programs in local governments. Based on the results of this analysis, the implications for the social integration policy of Korea were suggested.

The purposes of this study are to investigate the school science high achievers' achievements in enrichment physics, logical thinking level, and to analyze the relationship between logical thinking level and the achievement in enrichment physics of high achievers in science. The subjects were 357th and 8th graders who achieved highly in school science. To assess their achievements in enrichment physics, we developed a new test consisting of descriptive problems which were based on middle school curriculum. Those problems require one or two steps of thinking process, not simple knowledge of science. To assess logical thinking level, we used the instrument called GALT(Group Assessment of Logical Thinking) developed by Roadranka et al. The results showed that the school science high achievers' average achievement in enrichment physics was low, 56.3 out of 150, which indicated that they had not done much of enrichment learning beyond middle school science curriculum. Just only 54% of the school science high achievers are in formal logical thinking level. From the analysis of relationship between their logical thinking level and the achievement in enrichment physics, the value of the correlation coefficient was 0.174, which means that they are not almost correlated. Therefore, it is not desirable to judge science gifted children just from achievement in school science or enrichment physics, so both(logical thinking and the achievement in enrichment physics) tests should be taken for selecting gifted student.

This paper presents modeling and optimization techniques for hish efficiency solar cell process on single-crystalline float zone (FZ) wafers. Among a sequence of multiple steps of fabrication, the followings are the most sensitive steps for the contact formation: 1) Emitter formation by diffusion; 2) Anti-reflection-coating (ARC) with silicon nitride using plasma-enhanced chemical vapor deposition (PECVD); 3) Screen-printing for front and back metalization; and 4) Contact formation by firing. In order to increase the performance of solar cells in terms of efficiency, the contact formation process is modeled and optimized using neural networks and genetic algorithms, respectively. This paper utilizes the design of experiments (DOE) in contact formation to reduce process time and fabrication costs. The experiments were designed by using central composite design which consists of 24 factorial design augmented by 8 axial points with three center points. After contact formation process, the efficiency of the fabricated solar cell is modeled using neural networks. Established efficiency model is then used for the analysis of the process characteristics and process optimization for more efficient solar cell fabrication.

While there are various opinions about the relationship of Schiller's thought and Kant's, it is undeniable that Schiller owes much to Kant. What distinguished Schiller from other Weimar thinkers at his time, such as Goethe, Herder and Wieland, was that unlike them Schiller accepted Kant's project of critical philosophy. In fact, Schiller did not just accept it, but tried to interpret and formulate anew the relation of beauty and morality and some other aesthetical-ethical ideals on the basis of the new philosophy. Schiller's famous project of 'aesthetic education of mankind' itself is the product of such an endeavor. In this work we follow the history of Schiller's acceptance of Kant's critical philosophy and ruminate over its implications. And then, we'll show that Schiller's 'beautiful soul' in Grace and Dignity (1793), which is often suggested to be a proof of Schiller's conflict with Kant, was understood on the basis of Kant's moral theory. In this part of the work, we compare Schiller's ideal of the 'beautiful soul' and Shaftesbury's ethical thought, which is often presumed to be its background. From this comparison we'll be able to see that there is a considerable disparity, despite apparent similarities, between Schiller's and Shaftesbury's ethical ideals, which is due to their respective philosophical sources, that is neo-platonic metaphysics and Kant's critical philosophy.

The Mesozoic activity on the Korean Peninsula is mainly represented by the Triassic post-collisional, Jurassic orogenic, and Cretaceous post-orogenic igneous activities. The diversity of mineralization by each geological period came from various geothermal systems derived from the geochemical characteristics of magma with different emplacement depth. The Cretaceous metallic mineralization has been carried out over a wide range of time periods from ca. 115 to 45 Ma (main stage; ca. 100 to 60 Ma) related to post-orogenic igneous activity, and spatial distribution patterns of most metal deposits are concentrated along small granitic stocks. The late Cretaceous metal deposits in the Gyeonggi and Yeongnam massifs are generally distributed along the boundary among the Gongju-Eumseong fault system and the Yeongdong-Gwangju fault system and the Gyeongsang Basin, most of them are in the form of a distal epithermal~mesothermal Au-Ag vein or a transitional mesothermal Zn-Pb-Cu vein. On the other hand, diverse metal commodities in the Taebaeg Basin, the Okcheon metamorphic belt and the Gyeongsang Basin are produced from various deposit types such as skarn, carbonate-replacement, vein, porphyry, breccia pipe, and Carlin type. In the late Cretaceous metallic mineralization, various mineral deposits and commodities were induced not only by the pathway of the hydrothermal solution, but also by the diversity of precipitation environment in the proximity difference of the granitic rocks. The diversity of these types of Cretaceous deposits is fundamentally dependent on the geochemical characteristics such as degree of differentiation and oxidation state of related igneous rocks, and ore-forming fluids generally exhibit the evolutionary characteristics of intermediate- to low-sulfur hydrothermal fluids.

This paper explores the life cycle of innovation cluster, especially focussing on the Korean representative innovation cluster, Daedeok Innopolis. For this purpose, we review theoretically how an innovation cluster has been growing up. In particular, we discuss how a cluster has been formed and activated by governmental innovation policies from an evolutionary perspective. By doing so, the study identifies the typical features of an innovation cluster according to each dimensions of the cluster life cycle. The results of this study are as follows: First, in this study, Daedeok Innopolis has characteristics of latency, emergence, growth, and maturity from evolutionary perspective. Second, the governmental structure of the Daedeok Innopolis is a strong government-led and top-down structure, which has features of inclusiveness and flexibility such as umbrella policy. Third, the Daedeok Innopolis can be seen that adaptive or renewal development, as while, it can be applied fine adjustment the innovation cluster policy towards the recognition of innovation obstacle at each dimensions of the life cycle. Therefore, these discussions expose what kind of policy interventions should be addressed to form and develop the innovation cluster according to the cluster life cycle, as while, the development of adaptive policies during the risk and take-off period. Ultimately, the study provides that a different kind of policy instruments and tools should be implemented according to innovation cluster development and its distinctive characteristic per each dimensions of the cluster life cycle.

This study aims to provide educational implications for more strategic online software education by the types of online learning according to learners' self-regulated learning characteristics in the online software education environment and examining the characteristics of each type. For this, variables related to self-regulated learning characteristic were extracted from the log data of 809 students participating in the online software learning program of K University, and then analyzed using hierarchical cluster analysis. Based on hierarchical cluster analysis learner clusters according to the characteristics of self-regulated learning were derived and the differences between learners' learning characteristics and learning results according to cluster types were examined. As a result, the types of self-regulated learning of online software learners were classified as 'high level self-regulated learning type (group 1)', 'medium level self-regulated learning type (group 2)', and 'low level self-regulated learning type (group 3)'. The achievement level was found to be highest in 'high-level self-regulated learning type (group 1)' and 'low-level self-regulated learning type (group 3)' was the lowest. Based on these results, the implications for effective online software education were suggested.

In this study, we analyzed knowledge management cases of the Ministry of Culture, Sports and Tourism and examined knowledge management vision, promotion organization and knowledge management activity system. This study aims to clarify implications for successful knowledge management in government sector. In the case of the Ministry of Culture, Sports and Tourism, which was the subject of the study, it was evaluated as having performed well in the management activities of the government department in the evaluation of "Knowledge Target for 2018" jointly hosted by Maeil Economic Daily and the Ministry of Public Administration and Security. In this study, we conducted an in - depth interview with the knowledge management staff of the Ministry of Culture and Tourism and analyzed the success factors of knowledge management in the government sector. First, the vision of knowledge management and the role of dedicated organization were very important. In addition, knowledge management system was used to effectively acquire, share, and accumulate knowledge and utilize it. In addition, appropriate compensation systems for knowledge management activities are also important success factors. Therefore, in order to encourage knowledge management activities, it is necessary for public institutions to establish an incentive system such as an economic compensation system for personnel sharing activities and HR personnel.
