본 논문은 해양력이 동아시아 해양공간에 미치는 지정학적 파장과 그 성격의 문제를 다룬다. 마한의 도서국가지배론에서 강조되고 있는 해양력이 갖는 의미를 분석하고, 해양력의 지정학적 성격을 파악한다. 이러한 인식과 함께, 21세기 현재 중국이 도련선 전략을 통해 태평양으로 진출하고 있는 지정전략적 성격과 그 파장의 문제를 조사한다. 지난 20세기를 전후한 시기에 일본이 해양력에 기초해서 동아시아 해양공간에서 세력권 확장을 기획하는 대동아공영권 정책을 구체화했고, 21세기에는 중국이 도련선 개념을 구체화하면서 동아시아 해양공간을 관리하려는 지정전략을 구사하고 있다. 중국의 도련선 전략이 미국을 비롯한 동아시아 국가들의 반발에 직면해 있는 상황에서 한국외교의 해양세력 의존정책이 21세기 현재에도 유용한가에 대한 질문을 던진다.

This paper tries to analyze the efficiency structure and regulatory effects in electric power industry by using total factor productivity and indices based on cost function method. This paper performed an empirical analysis on the efficiency improvement and optimal scale taking the cost aspect in electricity industry into account. By expanding the cost structure framework, this paper proposes the analytical method regarding the needs of technology regulation and presents the empirical results which can be verified. Hence, this work can play a key role in decision-making of the national power development and regulatory policy. The empirical result indicates that the electricity industry in Korea has been in the state of economies of scale until 1980s, However, due to sustained growth of power generation, economies of scale declined and subsided after 1980s and then diseconomies of scale is shown recent years. The analysis on the effect of technology regulation shows the national large-scale base-load power plant development-oriented policy until so far contributed substantial cost effect to the electricity industry. The empirical result indicates that the reserve requirement as one of means of technology regulation policy did not contribute to the economies of scale but positive effect on the total factor productivity in Korea.

The purpose of this study is to dimensionally examine the factors of policy changes by applying the ACMS model to KEPCO's structural reorganization privatization policies and study its implications. As a result of the analysis, among the external variables that affect as a financial source or restriction to advocates, all areas except for the difference in opinion of the people as well as policy decision and effects of other subordinate systems were shown to be in an advantageous condition acting as a financial source to advocates of structural reorganization privatization. On the other hand, advocates affected by the external variables share a certain belief system in which the advocates of privatization share the justification of profitability while the advocates of collectivization share the justification of publicness. In these flows, the announcement of the privatization plan of public enterprises of the committee of planning and budgeting acts as a matter of contact which opens the windows for policy changes, and this window goes through ignition, explosion, and fixation which causes fierce interactions among advocates of both sides. Eventually, in accordance with the contents of excluding electricity(KEPCO) from the list for privatization the window for policy changes has closed and things have changed to a transitional KEPCO privatization policy. Based on this, the first implication is that non-official participants such as the people, social organizations, labor unions, etc. influence policy changes more than they did before. Secondly, in the process of policy changes, there is an order of boundary even in the fierce interactions between each advocate. Thirdly, specific variables can play various roles in complex policy phenomenon. Fourthly, a logical analysis using the ACMS model is possible in Korea as well. Fifthly, as a result of analyzing the change process of the KEPCO structural reorganization privatization policy through the ACMS model, not all matched with the main research results implied by the ACMS model.

The pressing need to mitigate greenhouse gas emissions has stimulated a renewed interest in nuclear energy worldwide. However, while numerous countries have shown interest in nuclear power over the course of history, many of them have not continued their pursuit and chosen to defer or abandon their peaceful nuclear power projects. Scrapping a national nuclear power program after making initial efforts implies significant challenges in such a course or a waste of national resources. Therefore, this study aims to identify the crucial factors that influence a country's decision to terminate or hold off its peaceful nuclear power programs. Our empirical analyses demonstrate that major nuclear accidents and leadership changes are significant factors that lead countries to terminate or defer their nuclear power programs. Additionally, we highlight that domestic politics (democracy), lack of military alliance with major nuclear suppliers, low electricity demand, and national energy security environments (energy import, crude oil price) can hamper a country's possibility of regaining interest in a nuclear power program after it has been scrapped, suspended, or deferred. The findings of this study have significant implications for policymakers and stakeholders in the energy sector as they strive to balance the competing demands of energy security, and environmental sustainability.

In this paper, we study the ON/OFF control policy of base stations in two-tier heterogeneous cellular networks to minimize the total power consumption of the system. Using heterogeneous cellular networks is a potential approach of providing higher throughput and coverage compared to conventional networks with only macrocell deployment, but in fact heterogeneous cellular networks often operates regardless of total power consumption, which is a very important issue of modern cellular networks. We propose a policy that controls the activation/deactivation of base stations in heterogeneous cellular networks to minimize total power consumption. Under this policy, the total power consumed can be significantly reduced when the traffic is low while the QoS requirement is satisfied.

미국은 우주분야에서 최고의 기술력, 인력, 자금을 확보하고 있는 국가이며, 우주의 영역을 단순한 과학기술 뿐 아니라, 산업, 국가안보와 깊이 연결시키고 있다. 반면 우리나라의 경우 우주정책이 위성, 발사체 등 우주시스템의 개발 위주로 되어 있다. 양국간의 우주정책 체계도 상이하다. 이로 인해 미국과의 우주협력을 얘기하는데 상호이해의 차이가 발생한다. 본 연구는 미국의 우주정책 체계를 소개하고 양국의 우주정책 체계를 비교함으로써, 미국과의 협력에 있어 효과적인 방안을 찾는데 목적이 있다.

As Indonesia is rich in natural resources, nuclear power remains a low priority among energy alternatives. However, Indonesia needs to introduce nuclear power to improve the atmospheric environment and to support sustainable economic growth. This study conducted a two-stage survey of logit-probit and analytic hierarchy process to analyze the perception of Indonesian energy policymakers regarding the introduction of nuclear power, the potential for change, and key decision factors. The analysis confirms that the perception of nuclear power is positive and that the willingness to expand nuclear power can improve if negative conditions, such as underdeveloped technology level, foreign aid and assistance, and safety issues are addressed. In addition, it is confirmed that the policy makers consider political/social and environmental factors to be more important for decision-making. The results of this study can give inplications and be used as a key reference for Indonesia's nuclear power policy

A Paradigm shift is in process in China's foreign policies during Xi Jinping's era. Such changes occur with changing national identities from developing country to great power, and from continental power to continental-maritime power. China's pursuit for sea power embraces its global strategy. Accommodating the new identity of maritime power, China is developing its maritime strategy. New silk-road strategy actively utilizes China's advantage in economy, while avoiding direct military challenges against the U.S. China seeks an associated balance of power with the U.S. On the other hand, China make its determination clear to protect its core national interests, particularly Taiwan straits issue, deploying Anti-Access and Area-Denial strategy. 'Pax-Americana 3.0' and 'China's rise 2.0' have convoluted and evolved in complexity. South Korea faces much tougher challenges ahead in its foreign and security environments.

This paper suggests a new paradigm of science and technology (S&T) policy for the purpose of the new national development that pursues not the scale expansion of a industrial production but the qualitative enhancement of industrial and S&T comparativeness. The new S&T policy paradigm includes new policy directions such as the density increasement of high quality- brain power and the energy supply for crossing the threshold from imitative R&D to creative R&D. Also, this paper argues that it is necessary not only to acquire the support of the local S&T community and policy-makers on the new S&T policy paradigm, but also to develop and implement policy measures in details on the basis of the new paradigm suggested by the paper.

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.
