Today's universities are adding economic development to their more traditional mandates of teaching and research. According, the need to foster student entrepreneurship has become increasingly important. The main aim of this research is to examine the effect of entrepreneurial education and various programs within the universities on students' entrepreneurial intentions and interests. The sample for this research majored mainly on the students who are attending the 18 universities, where entrepreneurship education and entrepreneurial programs were selected as the leading ones from the government. The data was obtained from the questionnaire distributed to the students of those universities. A total number of 1,000 questionnaires were distributed and 735 were retrieved back. Descriptive and chi-square analysis using the SPSS were considered most appropriate for the data analysis of the study used. The results of the analysis revealed that student's exposure to entrepreneurship education and various entrepreneurial programs have a important influence on the students' entrepreneurial intentions and interests. Examining the impact of entrepreneurial education and programs on students' entrepreneurial activities tends to raise or provide some useful insights into some theoretical issues on one hand. And on the other hand, it raises some practical implications for policy makers both in the government and universities.

Transport Social Overhead Capital refers to public utilities necessary for a nation's basic economic activities, and is divided into roads, railway, subway, ports and so on. It is important to be able to provide these SOC in the right place at the right time to enhance productivity and competitiveness of a nation. In this study, correlation and factor analysis on countries' socioeconomic and transport indicators were performed in order to understand the need for expansion of SOCs including railway, and to identify the impact they have on national competitiveness(productivity). As a result, GDP showed high correlativity(0.59~0.99) with factors such as population, land area, extension of available railroad, and road extension. Specifically, through the analysis of Russia's urban transport system and comparison between socioeconomic indices and SOCs of OECD countries, it was examined that how increasing transport infrastructure investments could enhance national competitiveness. In conclusion, opening new Light Rail greatly affects the growth of GDP followed by the increasing extension of available railroad. Furthermore, if available railroad extension is increased by 10 % from 2014, assuming high speed tram is opened, GDP will likely increase by 21.6%.

The standard is a nation's one of the most important industrial issues that improve the social and economic efficiency and also the basis of the industrial development and trade liberalization. This research analyzes the enactment and the utilization of Korean industrial standards(KS) of various industries. This paper examines Korean industries' KS utilization status based on the KS possession, enactments and inquiry records. First, we implement multidimensional scaling method to visualize and group the KS possession records and the nation's institutional issues. We develop several hypothesis to find the decision factors of how each group's KS possession status impacts on the standard enactment activities of similar industry sectors, and analyzes the data by implementing regression analysis. The results show that the capital intensity, R&D activities and sales revenues affect standardization activities. It suggests that the government should encourage companies with high capital intensity, sales revenues to lead the industry's standard activities, and link the policies with the industry's standard and patent related activities from R&D. Second, we analyze the impacts of each KS data's inquiry records, the year of enactments, the form and the industrial segment on the utilization status by implementing statistical analysis and decision tree method. The results show that the enactment year has significant impact on the KS utilization status and some KSs of specific form and industrial segment have high utilization records despite of short enactment history. Our study suggests that government should make policies to utilize the low-utilized KSs and also consider the utilization of standards during the enactment processes.

This research aims to analyze the effect of different types of urban parks and their locational characteristics on the apartment price in the entire metropolitan area of Busan, Korea. Although an urban park is an environmental good that influences the surroundings in many ways, most of the previous studies have underestimated its impact on the value of the surrounding area. This research focuses on the economic value of urban parks by understanding their relationship with the value of the apartments in the surrounding area with its significance in their physical and objective characteristics. Furthermore, the research emphasizes the different typological characteristics of urban parks in the analysis. In summary of the result, the number of levels (stories) and units of the apartment complex, ranking of the contractor, age of a park and accessibility to sub-central are positively related to the price of apartment units. On the other hand, the total area of apartment complex, the age of apartments, the distance to the nearest park and accessibility to civic-central or regional district are negatively related to the price of apartment units. Having a plan for constructing a park is also positively related to the price. For the typological characters of a park, neighborhood park, small-sized park, and sports park are positively related to the price, while children's park is negatively related to the price of apartment units. Considering that the price increases as the distance to the nearest park decreases, people prefer to live near the benefits that urban parks provide. In order to maximize the value and benefits that parks provide, it is necessary to approach them creatively.

As an increasing demand for rapid railway transportation, the construction of sidetrack is inevitable to operate local and express trains simultaneously. However, the current technologies for the sidetrack construction method require a long construction period by interrupting the operation of the existing subway line, as well as cause a huge economic loss. Thus, it is necessary to study the sidetrack construction method under the special situation that the subway is in operation and to analyze the risk of the existing tunnel enlargement process for the sidetrack construction. Therefore, in this paper, the Government Complex Gwacheon station on Subway Line 4 was considered as a target station for the virtual sidetrack construction and the optimal sidetrack construction plan was derived. Subsequently, the application of risk management process was carried out in the order of identifying risk, risk response planning, performing a risk analysis, risk monitoring and control for potential risk events during the construction of sidetrack under the subway operation. A total of eight potential risk events and risk mitigation methods were selected, and a risk assessment matrix was established using the five-step risk probability and impact level criteria to perform the risk assessment including residual risks. Based on the results of the risk assessment, the risk grade and the reduction effect of each risk mitigation method were confirmed.

In this paper, we suggest the conceptual design of a water-cooled reactor system for a low-pressure inherent heat sink nuclear desalination plant (LIND) that applies the safety-related design concepts of high temperature gas-cooled reactors to a water-cooled reactor for inherent and passive safety features. Through a scoping analysis, we found that the current LIND design satisfied several essential thermal-hydraulic and neutronic design requirements. In a thermal-hydraulic analysis using an analytical method based on the Wooton-Epstein correlation, we checked the possibility of safely removing decay heat through the steel containment even if all the active safety systems failed. In a neutronic analysis using the Monte Carlo N-particle transport code, we estimated a cycle length of approximately 6 years under 200 $MW_{th}$ and 4.5% enrichment. The very long cycle length and simple safety features minimize the burdens from the operation, maintenance, and spent-fuel management, with a positive impact on the economic feasibility. Finally, because a nuclear reactor should not be directly coupled to a desalination system to prevent the leakage of radioactive material into the desalinated water, three types of intermediate systems were studied: a steam producing system, a hot water system, and an organic Rankine cycle system.

This study focuses on immigrant women who are married to Korean men and who live in a multicultural family situation in Gyeonggi-do. These women experience acculturative stress and marital conflict and this study aims to determine how social support seeks to mediate the effects of those stressors. The women in this study participated in activities and received services from one of Gyeonggi-do Province's civic organizations, religious organizations, or social service organizations, such as the Social Welfare Agency and the Multicultural Family Support Center. In order to verify the study's hypothesis, the researchers used the following statistical analytical methods : t-test, two-way ANOVA and multi-regression analysis. Analysis of the study's results showed that the highest degree of marital conflict was found in the sub-zones and variables that were personal. Those variable were : the difference in mindset and values (personal domain), economic problems (communal living area), a child's upbringing and education issues (third party area), and the participant's sex life (in the marital relationship). The hypothesis was tested using the research model validation and the results are summarized as follows. First, in order to analyze the relationship between the marriage migration females' acculturative stress and the impact of that stress on marriage conflict, the hierarchical regression analysis was used. It identified that a direct correlation existed between acculturative stress and marriage conflict; where a higher degree of acculturative stress was present, a higher degree of marriage conflict was found. Second, the study found a statistical significance in the correlation and relationship (${\beta}$=.208, p<0.05) between the acculturative stress of the marriage migration female and material support. In other words, the material support can be seen as having a moderating effect on the acculturative stress, which is the independent variable, and the marital conflict, which is the dependent variable.

Amine volatility occurring on the $CO_2$ capture process may result in significant economic losses and environmental impact. In this study, using an volatility measurement apparatus, we measured a amine volatility of various amines including MEA(Monoethanolamine), MDEA(N-Methyldiethanolamine), Pz(Piperazine), AMP(2-Amino-2-methyl-1-propanol), 2-MP(2-Methylpiperazine), DGA(Diglycolamine). For the quantitative analysis of volatility, we analyzed the effects of temperature and $CO_2$ loading using an gas chromatography analysis. The result shows that the amine volatility was increased by increasing Henry's constant(MDEA$-CH_3$)(for AMP).
