Using the plant level panel data on Korean manufacturing during 1990-98 period, this study tries to assess the role of entry and exit in enhancing aggregate productivity, both qualitatively and quantitatively. Main findings of this study are summarized as follows. First, plant entry and exit rates in Korean manufacturing seem quite high: they are higher than in the U.S. or several developing countries for which comparable studies exist. Second, in line with existing studies on other countries, plant turnovers reflect underlying productivity differential in Korean manufacturing, with the "shadow of death" effect as well as selection and learning effects all present. Third, plant entry and exit account for as much as 45 and 65 percent in manufacturing productivity growth during cyclical upturn and downturn, respectively. The findings of this study show that the entry and exit of plants has been an important source of productivity growth in Korean manufacturing. Plant birth and death are mainly a process of resource reallocation from plants with relatively low and declining productivity to a group of heterogeneous plants, some of which have the potential to become highly efficient in future. The most obvious lesson from this study is that it is important to establish policy or institutional environment where efficient businesses can succeed and inefficient businesses fail.

The purpose of this paper is to highlight the importance of conflict management by local government by explaining a peculiar case of Namyangju city's construction project of landfill site for incineration remnants. Policy stage and internal dynamics of conflict between city and opposition group of local residents are used as major tools of case observation. From this analysis, this study finds that the conflict management effort of local government is critical to bring a success of a public policy. The local government needs to assess possible sources of conflict, and to prepare reasonable solutions through sincere communication with local residents. Also we need to reconsider the concept of administrative efficiency. Sometimes "slow" is better than "fast". Authoritative and hasty policy process may face unexpected obstacles, then consume more time to fulfill the policy goals. It means that the local government needs to spend more time for policy formulation. It also shows the importance of democratic process in reaching a public policy decision. In conclusion, this study confirms that the cooperative relationship between local government and residents, so-called governance, is the key to the success of public policy.

Recently many companies began to feel the pressures of cost savings due to the global recession, so they have been interested in the Cloud Computing. Cloud Computing is one of using method of IT resources through the network. Users can borrow softwares or hardwares instead of buying them. Many people expect remarkable growth in Cloud Computing industry because of it's effectiveness. But Cloud Computing industry is still at an early stage. Especially, people who in the public sector hesitate to adopt Cloud Computing Services due to security issues and their conservative views. Also, they just have limited understanding, so we need to investigate what they really know and understand. Researches about the Cloud Computing generally focus on technical issues, so we can hardly find researches reference for decision making in considering the services. The study aims to investigate diverse factors for agencies' adoption decisions, such as benefits, costs, and risk in developing the most ideal type of cloud computing service for them, and performs priority analyses by applying ANP (Analytic Network Process). The results identify that features pertaining to the risk properties were considered the most significant factors. According to this research, the usage of private cloud computing services may prove to be appropriate for public environment in Korea. The study will hopefully provide the guideline to many governmental agencies and service providers, and assist the related authorities with cloud computing policy in coming up with the relevant regulations.

This study aims to explore how the individual characteristics of the senior job placement project coordinators and the organizational structure in which they work affect their job performance. A survey of 251 coordinators who were working in the senior job placement project agencies were retrieved and used for empirical analysis using the SPSS Win.12 program. The result shows that a sense of self efficacy, the individual traits(understanding of the senior job placement project, attitude towards the elderly) and the organizational structure(the level of formalization of agency) were statistically significant predictors of the level of job performance. The results of this study show that the coordinators who were more confident about themselves, who had more understanding about the senior job placement project, who had more positive attitude towards the social activities of the elderly, and who were working in agencies with higher level of formalization had a higher level of job performance than their counterparts. Therefore, more policy and program considerations should be taken into account in empowering the coordinators, and in providing them with standardized organizational process. This in turn will ultimately enable them to better serve the elderly who participate in the senior job placement projects.

The stock market is affected by unexpected factors, such as politics, society, and natural disasters, as well as by corporate performance and economic conditions. In recent days, artificial intelligence has become popular, and many researchers have tried to conduct experiments with that. Our study proposes an experiment using not only stock-related data but also other various economic data. We acquired a year's worth of data on stock prices, the percentage of foreigners, interest rates, and exchange rates, and combined them in various ways. Thus, our input data became diversified, and we put the combined input data into a nonlinear autoregressive network with exogenous inputs (NARX) model. With the input data in the NARX model, we analyze and compare them to the original data. As a result, the model exhibits a root mean square error (RMSE) of 0.08 as being the most accurate when we set 10 neurons and two delays with a combination of stock prices and exchange rates from the U.S., China, Europe, and Japan. This study is meaningful in that the exchange rate has the greatest influence on stock prices, lowering the error from RMSE 0.589 when only closing data are used.

The purpose of this study is to examine the relationship between self-leadership of teachers who conduct free-selection activities in kindergartens. In addition, we analyze the mediating effect of teacher self-efficacy. This study was conducted using data gathered through a survey conducted on 325 kindergarten teachers in Seoul and Gyeonggi-do areas from September 17 to 28, 2018. To analyze the data, the author used SPSS Statistics 22.0 and AMOS 20.0 programs to conduct reliability analysis, confirmatory factor analysis, correlation analysis, and structural equation modeling. The result of the verification of the hypothesis showed that self-leadership of kindergarten teachers who engaged in free-selection activities positively influenced self-efficacy. Self-leadership of teachers who employed free-selection activities had a positive effect on the expertise of teachers as well. Also, self-efficacy of kindergarten teachers positively affected expertise of these teachers. In addition, the self-leadership of kindergarten teachers mediated self-efficacy, so that the indirect effect on teacher expertise was statistically significant. Also, the direct effect of self-leadership on expertise of teachers was significant, which showed that the self-efficacy of the kindergarten teachers indirectly mediated the relationship between self-leadership and expertise of the teachers. This study showed that to enhance expertise of kindergarten teachers, this requires enhancing self-leadership of teachers. Also, in order to enhance the level of self-efficacy of teachers, necessary knowledge and skills that can enhance self-efficacy of these teachers in their working environment should be provided.
