This study examines how managerial ownership structure affects the borrower's choice of private versus public debt using 2,608 firm-year data for 2006-2008. This paper investigates the relationship between managerial ownership structure and debt choice. Managerial ownership is measured using number of stocks and unexercised stock-options and debt is classified public and private debt. The results find that there is a positive association between managerial ownership and the private debt dependence and also find that when firms finance additional funds, higher managerial ownership leads managers to choose private debt not public debt. Since private debt can be classified into bank debt and non bank debt, this paper examines the relationship between managerial ownership and a choice of bank debt. The results indicate that managers with higher ownership are more likely to use bank debt over public debt and non bank debt. By examining the relation between managerial ownership and a debt choice, this paper has following contributions. First, this study shows that managerial ownership affects the choice of the source of financing using three different proxies of managerial ownership. Second, this study classified private debt into bank debt and non-bank debt and provide the evidence of preference toward private debt especially bank debt among other financing sources. Finally, there are extensive studies related to capital structure and managerial ownership, but there is little empirical research on the debt choice and managerial ownership. Thus, this paper adds to literature by exploring the effects of managerial ownership on a debt choice.

This study empirically test the roles of network closure and structural hole on radical innovation in technological knowledge exchange network in Gumi cluster. In doing so, we build 2,550 firm network, transforming association*firm(2-mode) to firm*firm(1-mode) network data. In addition, in order to investigate firms' attributes, we conduct survey for 101 firms in Gumi cluster using random sampling, and finally collect 86 firm samples. For analysis, we use ridge regression since network density and efficiency, indices of network closure and structural hole respectively, has a high level of multicollinearity. The findings show that structural hole has a significant and positive impact on radical innovation, but network closure has a significant and negative impact on radical innovation. This study contributes to present an empirical evidence of debate on network closure and structural hole based on past conceptual discussions and literature review and further goes a long way towards strategy formulation to establish social capital in accomplishing radical innovation. Further research is required that pays closer attention to features of technological knowledge, innovation types and interaction between network closure and structural hole, directing efforts to structural characteristics of various networks.

Traditionally, self-efficacy, burnout and engagement are defined as work related states of mind, and formally speaking, students are not employees. But, we assume that from a psychological perspective, student core activities can be considered work. Therefore, based on SCT(social cognitive theory), we examine the mediating role of self-efficacy in the prediction of student burnout and engagement, and also the mediation of burnout and engagement between self-efficacy and performance(GPA). There is no research to date wether there would be mediating role of these variables between past success and performance. These effects were analysed in the context of mediating role of the variables in a university in a sample of 438 students. This study utilized a convenience sample drawn from various major scholar area. Results of structural equation modeling analyses were consist with a full mediation model in which academic past success predicts self-efficacy, which in turn, predicts student burnout and engagement. Also our proposed model showed that burnout and engagement are partial or full mediating variables between self-efficacy and performance. Our study's findings provide evidence that engagement fully accounted for the relationship between self-efficacy and performance, and burnout partially explained the relationships. These findings aligns with the general theorizing supported by JD-R model and SCT(social cognitive theory). More specifically, it builds on the JD-R literature as it tests one of the proposed mechanisms in the relationship between job resources and work engagement. Implications of study are discussed, together with limitations and suggestions for future research.

The purpose of this study was to examine university students' understanding of the nature of science, an aspect of scientific literacy, which is the goal of modern science education. To accomplish this, the differences and similarities by gender and major. on college students' understanding of the nature of science were investigated. 'Understanding of the Nature of Science' developed by Lee (2003) was implemented for this study. The instrument has three sub-scales; a scientific world view, scientific inquiry, and scientific enterprise. The instrument is only expected to give, and provides meaningful information on student understanding of the nature of science. A total of 120 college students, majoring in science education, liberal arts, and physical exercise participated in this study. Science education major students were verified to have a better understanding of the nature of science followed by liberal arts students and then physical exercise students. Moreover, men revealed slightly more comprehension that of women. More than 80% of students, majoring in science education, answered 11 out of 23 questions, approximately 50%. In the area of scientific inquiry, both science education and liberal arts students showed more comprehension that those in physical exercise. All participants showed relatively lower comprehension of the definition of scientific contribution than other subjects, but displayed a greater comprehension of the ethics of science. On the other hand, most students have relatively low apprehension in the contribution of science, while higher apprehension in the ethics of science.

러시아와 한국간의 공식적인 접촉은 1990년 6월 샌프란시스코에서 개최된 정상회담이다. 동년 9월 뉴욕에서 개최된 양국의 외무장관 회담에서 러시아와 한국의 외교관계가 수립되었다. 그간 양국간에는 협정을 통한 협력의 법적기반이 조성되었는데 주요 분야를 보면 무역, 투자보장, 어업, 이중과세방지, 군사기술분야, 원자력의 평화적 이용, 문화교류에 관한 협정들이 있다. 역시 양국간의 주요 관심사항은 무역과 경제협력 분야이다. 2007년도 러시아와 한국의 무역액은 150억 달러를 초과함으로써 전년도에 비해 55.5% 증가하였다. 러시아의 한국으로의 수출은 약 70억 달러로서 전년도에 비해 52.6% 증가했고 한국으로부터의 수입은 80억 달러를 초과함으로써 전년도에 비해 56.1% 증가하였다. 그리하여 러시아는 한국의 10대 교역국으로 성장하였다. 가스와 오일 프로젝트 추진과 관련하여 사할린지역에서 사용하기 위해 한국으로부터 수입하는 드릴기계장비, 탱커, 자동차, 휴대전화는 한국과 러시아 양국간 경제성장의 주요요인이 되고 있다. 2008년 1/4 분기 양국간 무역액은 42억 달러를 초과했는데 이는 전년도 동기와 비교해서 72.1% 증가한 것이다. 이 중 한국에의 수출은 17억 달러를 초과했는데 이는 전년도 1/4분기에 비해 91.7% 성장한 것이다. 한국으로부터의 수입은 약 25억 달러로서 전년도 1/4 분기와 대비해서 60.6% 성장했다. 러시아와 한국간의 경제교류가 크게 증대하게 된 배경에는 러-한경제과학기술협력공동위원회가 큰 역할을 담당했다. 이 논문에서 필자는 무역과 투자측면에서 본 양국간 경제협력의 특징을 고찰하는 한편 러시아의 동부지역(러시아 극동 및 바이칼횡단지역)과 한국과의 협력과 관련된 역동성과 과제를 제시하는데 연구의 목적을 두었다. 한국은 외국기업과 함께 러시아 극동지역의 무역과 경제협력 증진에 상당한 공헌을 함으로써 러시아 극동경제권에서 주요 무역파트너가 되고 있다. 또한 본 연구에서는 한국과 러시아간의 주요 협력프로젝트에 관하여 고찰하는 한편 앞으로의 전망을 제시하였다. 이 문제는 무엇보다도 한-러간의 공동 에너지프로젝트 및 에너지자원의 무역과 관련되어 있다. 한국과 러시아는 이미 많은 분야에서 상당한 정도로 상호 협력관계를 발전시켜왔다. 여기에는 정책, 에너지, 경제, 문화, 과학기술 분야가 포함되어 있다. 현재 러시아와 한국간에는 에너지 분야에서의 전략적 대화채널 구축에 관한 문제와 함께 연료 및 에너지공단 건설과 관련하여 협력문제가 논의되고 있다. 에너지 분야에서의 전략적 대화개념 구축을 위해서는 전략, 예측 및 투자환경의 문제가 양국간에 집중논의 되어야 하고 법제상의 조화문제도 논의되어야 한다.

With the 500th anniversary commemoration of Gerard Mercator's birth in 2012 now passed, there is the possibility that his name will fade back into obscurity. This would be both unfair and pitiful, because Gerard Mercator's name should be highly regarded as one of the principal contributors to navigational science and the promotion of marine safety. An accomplished cartographer, in 1569 Mercator published a remarkable 18-folio world map, depicting the then-known world in a new format with straight rhumb lines. While this distorted the size of land masses, particularly in higher latitudes, this new projection made navigation much easier for now all sailors had to do was to draw a straight line between two points to plot their course. Mercator clearly had this navigational benefit in mind, though his contemporaries did not immediately recognize its value. It wasn't until after Mercator's death, when Edward Wright (1599) and Henry Bond (1645) used and explained the new projection and demonstrated the use of straight rhumb lines in navigation that the Mercator projection became the standard for sea charts. Today, 450 years later of his death, electronic charts still rely on the projection Mercator invented and developed, confirming his position as a giant in the history of navigation. This paper introduces his life and work, detailing the importance of the 1569 world map and its contribution to navigational science and safety.

The purpose of this article is to analyse the military thought of Ferdinand Foch and to present its contemporary meanings. 1.Foch's life: Since 1871 to end of World War I, he acted as a military philosopher, battle field commander, and Supreme Commender of the Unified Forces so as to be judged as Clausewitz of the 20th century. 2. Historical Background of Foch's Activity Period : The series of the domestic revolutions after Napoleon's downfall were extended to Europe for independence, unification and overseas colonial wars. Thus Foch's growing and acting period was in totally imminent danger at all fields. 3. Foch's Military Thought : Through his three books, he argued cleary the absolute importance of the immaterial power including the technical esteem and the offensive fighting will for the victory. 4. The Contemporary Application of Foch's Thought : Though the operation plan based on Foch's strategic thought was defeated at the early stage of the World War I, its offensive-oriented immaterial spirit power should be remembered. 5. Conclusion : Foch's thought which develops the penetration through the war history and emphasizes the importance of the immaterial power should be highly appraised. Thus it should be also reinterpreted and redeveloped into a modern contemporary meaning.

This paper aims at examining the existence and characteristics of regional difference in project finance in Korea. Main results of this paper are as follow. Firstly, regional difference in project finance between capital region and local can be seen partially. However, their characteristics are different from corporate finance. ANOVA tests show significant differences of excess interest rate occur in case of commercial real estate projects and significant differences of contracted terms occur in case of residential real estate projects carried out by local banks. Secondly, key factors causing the regional differences in project finance are asymmetric information for cash flow generated by the project between the capital region and local. Especially, regional differences in project finance are different from those in corporate financing because of local banks$^{\circ}{\phi}$ behaviors. They follow and act as the passive members of nationwide banks in case of the capital region projects. Thirdly, prepaid sale system and the guarantee system depending on construction companies dilute the regional differences in project finance in case of residential real estate projects. Although these systems contributed rapid growth of project finance, they may be the main factors distorting project finance market which lead to financial crisis. In these context, policy implications may be derived in order to solve the confronted problems of project finance market.

The paper aims to understand the concept of social innovation and its development stages emerging as a new regional development policy trend and to define the role of public sector for social innovation. Spatial policy issues that urban development corporations to carry out development projects for regional policy need to deal with have expanded to include crucial social issues such as poverty, quality of life and happiness. Therefore it is increasingly significant for them to take social innovation into consideration. In this context, this study formulates evaluation framework for the role of public sector in social innovation and investigates its position and limitation in social innovation practices. As a result, almost all corporations have made various efforts for promoting both public purposes of housing and land development and social contribution for the community. However, few corporations have achieved organizational capacity building and idea implementation for social innovation. Growing demand for social innovation in both spatial and regional policies tends to bring up profound challenges to public regional development agencies including urban development corporations. It is then a time to seek to carry out related researches and policy option formulation for social innovation in the near future.

The American military occupations of Korea(1945-1948) and Japan(1945-1952) after the second world war had great influences on the history of the two countries, the contents and results were, however, quite different. This study attempts to analyze the similarities and differences, the determinants of the social welfare policy, and their long-term effects on the later social welfare policies in the two countries. For the purpose of this study, it uses a comparative case study on the public assistant policies of the two countries during the American military occupation. The conclusions of this study are summarized as follows. Firstly, although the American military occupations of the two countries faced the similar social problems during the same period, their countermeasures were quite different from each other. In Korea, the American military occupation hardly tried to establish a substantial social welfare system by making laws, but, mainly relying on temporary emergency relief, they just aimed for social control. On the other hand, in Japan, the American military occupation tried to improve the existing social welfare system in terms of the principles of demilitarization and democratization. Secondly, the political determinants of the social welfare policy in the two countries were much more important than the socioeconomic determinants. Especially the differences in the basic military occupation principles, the administration structure, and the roles of the indigenous ruling classes acted upon the different social welfare policies of Korea and Japan. Thirdly, the long-term effects on the later social welfare policies in the two countries was different. In Korea, the American military occupation hardly contributed to modernize the social welfare policy. Therefore, the unsystematic premodern relief system continued to exist for a long time. On the other hand, in Japan, the American military occupation contributed to modernizing the social welfare policy in terms of ideology and system and formed the groundwork for developing the later social welfare policies.
