The objective of this study focuses on the relationship between increasing of leverage and income, asset purchase. For empirical test, regression analysis was conducted using panel data of the household financial welfare survey. The results of the analysis are as follows: First, increasing of leverage is determined by the asset purchase. Deleveraging can be realized by reducing the size of the assets. Second, increase of leverage has positively affected on the increase of asset. Also, the increase of income has significantly positive influence on the increase of assets. These results provide practical guidance as research in increasing of leverage and increase of asset and the limitations of the research and future study are discussed as well.

The agency relationship between managers and shareholders has the potential to influence decision-making in the firm which in turn potentially impacts on firm characteristics such as value and leverage. Using an agency framework, we examine the relation between ownership structure and capital structure during post-IMF period. We used the balanced panel data for 378 korean listed companies during the 1999-2005. The panel data sets consist of time-series observation on each of 378 cross-sectional units. The results indicate a non-linear U-shaped relation between the level of managerial share ownership and leverage with the relation reaching a minimum at 58.48 per cent of management share ownership. As managerial share ownership increase from a low level, managers have incentive to reduce the debt level for decreasing the financial risk, resulting in a lower lever of debt. However, when corporate managers hold a significant proportion of a firm's shares, managers have incentive to increase the debt level for leverage effects, resulting in a higher lever of debt.

As a cutting edge technology intensive value-added business, the defense industry is jumping into a new engine of a national growth. Also, the defense industry export is recognized not only as the field to activate the Korean economy but also as an important field to create the national brand value. However, though the consensus on the importance of defense industry export helps achieve the remarkable performance in reality, the rate of increase in the budget for national defence is slowing down gradually, and the investment in R&D is not so big, and there are a lot of drawbacks with the management of core technology and the development of cutting edge weapon system. Accordingly, this thesis tried to find the leverage to make the structure of defense industry export work normally after analyzing the systematical structure of defense industry export to understand its characteristics. Also, through the process to make the leverage a strategy, the thesis tried to present the optimal direction of policy to join the ranks of the advanced countries in defense industry export.

본 연구에서는 우리나라 234개 상장기업을 대상으로 기업의 소유구조와 자본구조의 상호관계가 기업다각화에 미치는 영향을 2단계 최소자승법(2SLS)을 이용하여 분석하였다. 우리나라 기업의 소유구조와 자본구조의 상호관계를 분석한 결과를 요약하면 첫째, 1996년부터 1999년까지의 전기간 분석에서 우리나라 기업은 소유구조와 자본구조 정책을 서로 연계하여 결정하는 것으로 나타났다. 그러나 IMF 경제위기 전후기간으로 구분하여 상호영향관계를 분석한 결과에 의하면 IMF 이전기간에는 소유구조와 자본구조가 상호의존적인 영향관계가 있는 것으로 나타났지만, IMF 이후기간에는 소유구조와 자본구조의 상호영향관계를 발견할 수 없었다. 둘째, 내부자는 부채사용에 따른 재무위험의 부담을 줄이기 위해 레버리지 비율이 높으면 내부지분율을 감소시키는 것으로 나타났다. 넷째, 내부지분율이 높으면 내부자는 자신이 부담해야 하는 재무위험을 줄이기 위해 레버리지 비율을 낮추는 것으로 분석되었다. 한편, 소유구조와 자본구조의 상호관계가 기업다각화에 미치는 영향을 분석한 결과에 의하면, 소유구조와 자본구조의 상호관계가 기업다각화 수준에 영향을 미치지 않는 것으로 나타났다.

The Korean defense industry was brought up in the government policy since 1970's. The important parts of defense industrial technologies have not been developed, and usually introduced from overseas. Moreover, the development of advanced technologies was not actively stimulated or pursued, consequently shaping the current structure of the defense industry which lacks global competitiveness due to the dearth of high technologies necessary for high-technology weapons. This research analyzes the systems of the Korean defense industry through a systems thinking approach in order to understand the whole mechanism and to find ways to improve the defense industry. Finding some leverages is the main purpose of systems thinking, that yields desirable results with a little effort. The three policy leverages are: (1) the policy for timely fielding; (2) the R&D investment for development and production of domestic high-technology weapons; and (3) the policy measures for exports. The research findings will contribute to the invigorating and developing the Korean defense industry by providing policy-makers and acquisition practitioners with systematic understanding and insight into the dynamics of the defense industry for them to make and execute efficient policies taking into account the Korean overall defense industry.

South Korea has the defense burdensharing agreement with the United States in reference to the U.S. troops stationed in Korea since 1991, based on Special Measure Agreement(SMA). Due to the growth of Korea's economic power and the U.S. provision of the security environment on Korean penninsula, the U.S. government steadily demanded the rise of contributions to common defense from South Korea and South Korea accepted most of the U.S. requests without proper principles of negotiation concerning the cost sharing. This paper analyzes the systems of the Korea－U.S. cost sharing program through a systems thinking, that yields desirable results with a little effort. The three policy leverages are: 1) the development of negotiation principles; 2) the policy making closely linked with National Defense Reform Basic Plan; 3) the policy making with responsibility burdensharing than cost burdensharing. This paper findings will contribute to the developing the Korea－U.S. cost sharing program by providing policy－makers and policy-practitioners with systematic understanding and insight into the dynamics of the program. Also, this will enable the program to execute more effectively with a concrete formula.

As the network composed of numerous sensor nodes, sensor network conducts the function of sensing the surrounding information by sensor and of the sensed information. The concept of the battlefield is also changing to one that includes not only physical spaces but all areas including the networks of the nation's key industries and military facilities, energy facilities, transportation, and communication networks. In light of the changing warfare in terms of how it is conducted and what form it takes, the Korea military has to seek ways to effectively respond to threats of cyber warfare. In the past, although partial strategies on cyber warfare were studied, no research was done through the overall system flow. In this paper, key variables related to cyber warfare security are classified into personnel, management, and technology. A simple model and an extended model are suggested for each area, and based on the technology area of the extended model, formal methods are used to verify the validity and a detailed response strategy is suggested according to the identified leverage.

In the internet portal industry, the indirect network externality from portal visitors to advertisers and the direct network externality among portal visitors have important implications for anti-trust policies. This paper examines the existence and the magnitude of the direct/indirect network externality in the Korean internet portal industry and measures its effect on the market power of the internet portals. The results show that the direct/indirect network externality is substantive in the industry hence the market share of a portal in the visitors' side has the 'leverage' effect on its market power in the advertisers' side.
