The industrial ecosystem around the Internet services has been evolving since the Internet was first introduced. The Net Neutrality issue best represents the process of the evolution and presents an inevitable challenge that the industry should overcome. This paper deals with this structural change with the Two-Sided Market framework and provides a System Dynamics(SD) model to evaluate the economic implications of the net neutrality policy. In particular, our approach analyzes the policy impacts when two competing platforms (network providers) play a role of the platform in a typical two-sided market, which connects Content Providers(CPs) with users. Previous studies show that the indirect network externality between these two markets makes the entire system tip to one platform. When the multi-homing in the CP market is allowed as in our model, however, their argument may lose its validity. To examine the system behavior, conducted here is SD simulations of our model. The simulation results show that co-existence of the competing platforms persists with the network effects over a certain threshold. The net neutrality policy seems to lower the threshold based on our experimental outcomes.

This paper investigates the cyclical behavior of UI benefit take-up rate, the share of unemployed persons who are eligible for job seekers' allowances(JSA) and actually receive them. Using Korea's Employment Insurance DB, it also identifies the factors linked to the decision to take up job seekers' allowances. The results show that the take-up rate is countercyclical and leads both unemployment rate and Coincident Composite Index cyclical component by 6 months and is positively correlated with replacement rate and benefit duration, suggesting that extending benefit duration and raising benefit level can boost benefit claims to increase take-up rates in Korea.

Purpose - to examine the theories related to the internationalization of multinational corporations as well as theories related to internationalization of small and medium-sized enterprises. Research design, data, and methodology - traditional theories, e.g. eclectic paradigm and behavioral theory and product life cycle etc. were examined and recent advances theories - network theory, entrepreneurship - were also examined to outline the theory of internationalization of firm. Results - the main schools of international researches are divided into two; one is the economics school, the other is the behavioral school. The economics school has considered internationalization as a pattern of investment in foreign markets explained by rational economic analysis of internalization, ownership, and location advantages. Apart from the economics approach, a theory relevant to smaller firms highlights slow and incremental overseas market commitment. Recent research on the network perspective is fast emerging and it can be applied and well explained on the internationalization of smaller firms, focusing on firm behavior in the context of a network of interorganizational and inter-personal relationships Conclusions - Small medium-sized enterprises have been recently rising, however, there has still been little consolidation of literature in internationalization and most of the relevant theories have been still focusing on explaining the globalization of multinational corporations. Little studied on the internationalization in the context of smaller firms which are distinctly differentiated from larger firms including international new ventures, which the motivation to study strongly calls for more information and studied on small medium-sized enterprises.

Recently, interest in eco-friendly structure has been increased and many researches about hwang-toh are being actively processed. However, most researches are about material properties of hwang-toh, and researches about structural performance are insufficient. Moreover, the usability of activated hwang-toh is being identified in some ways, but its use rate is low in economic aspect in reality. Non-activated hwang-toh is expected to be advantageous in respect of economy but its material and structural performance have not been identified. Therefore, the effect of activated hwang-toh and non-activated hwang-toh on flexural capacity of hwang-toh concrete beam is analyzed in this research.

This study aims to understand the experiences as consumers of Thai students studying in Korea. "Study Korea Project" which is a drive to globalize local universities by attracting more oversea students as a pull factor, and economic growth, values on education and Hallyu as push factors contribute to the increase the number of Thai students in Korea. In order to understand the experiences of Thai students as consumers studying in Korea, individual interviews were conducted. A total of 5 participants were asked about meaning of consumption in everyday life in Korea or any changes in consumption behavior compared to living in Thai. Three themes were identified through wholistic and selective approaches. First, all participants in the study said that they were surprised because of high living expense in Korea. Consequently, survival itself is too much for them and they have become more conscious of prices of goods. Secondly, since most participants in this study can control their own budget, they feel some degree of freedom and power of control of their own lives. This experience may help them to accomplish their developmental tasks during the transition to adulthood. Thirdly, they are easily imbued with Korean consumer culture. It causes various conflicts between buying and not-buying or friends gathering and saving money. Sometimes it makes them in stuck excessive consumption and financial problems. For a deeper understanding of oversea students' lives in Korea as consumers, further studies should take into consideration of not only their culture of origins, but also misconceptions that have accumulated around these students.

This study examined the influences of general characteristics, maternal parenting behaviors and children's self-control ability on children's social competence. A total of 416 children in the fifth and sixth grades responded to questionnaires, which included items related to their social competence, their mothers' parenting behavior, as well as their own self-control ability. Data were analyzed by means of Pearson correlation analysis and the hierarchical regression analysis method. According to the results of the hierarchical multiple regression analysis, children's self-control ability best explained their social competence. In terms of individual factors, motivational self-control had the greatest effect on social competence, followed by cognitive self-regulation, behavioral self-regulation, economic level, gender and grades, in that order. The results for the effects of maternal parenting behaviors and children's self-control ability on children's social competence highlighted the important roles played by the mother and the child's self-control ability in improving the child's social competence. The study contributes to the literature by providing fundamental insights into children's higher quality of life.

The purpose of this study was to find out whether home environmental variables had a greater effect on adolescents' violence against parents. The results of self-reporting questionnaires are as follows ; The victims of violence are mainly mothers. The socio-economic status didn't influence on the degree of violence against parents. The adolescents of the extreme family type used more serious violent behavior. The higher the degree of observed and experienced violence is, the higher the degree of violence against parents. Also, the higher the degree of home education is, the lower the degree of violence against parents. Of all variables, the observed violence and structure-environmental variables account for 37.6% of adolescents' violence against parents. The results of in-depth interview showed that birth-order didn't affect violence against parents. The victims of violence were mainly stepmothers and stepfathers. These parents' educational attitudes were disagreement in parents, seriously inflicted corporal punishment and were indifferent to adolescent. Also, interviewed adolescents were observed and experienced violence in home and used violence against others.
