End-to-end network delay plays an vital role in distributed services. This delay is used to measure QoS (Quality-of-Service). It would be beneficial to know all node-pair delay information, but unfortunately it is not feasible in practice because the use of active probing will cause a quadratic growth in overhead. Alternatively, using the measured network delay to estimate the unknown network delay is an economical method. In this paper, we adopt the state-of-the-art matrix completion technology to better estimate the network delay from limited measurements. Although the number of measurements required for an exact matrix completion is theoretically bounded, it is practically less helpful. Therefore, we propose an online adaptive sampling algorithm to measure network delay in which statistical leverage scores are used to select potential matrix elements. The basic principle behind is to sample the elements with larger leverage scores to keep the traits of important rows or columns in the matrix. The amount of samples is adaptively decided by a proposed stopping condition. Simulation results based on real delay matrix show that compared with the traditional sampling algorithm, our proposed sampling algorithm can provide better performance (smaller estimation error and less convergence pressure) at a lower cost (fewer samples and shorter processing time).

The year 2010 has been regarded as a year of China's assertive diplomacy. A series of China's behavior--including China's critical reaction to the U.S. for its sales of weapons to Taiwan, the Dalai Lama's visit to President Obama, China's arbitrary designation of 'core interests' over the South China Sea, China's inordinate reactions to the sinking of the Cheonan and Yeonpyeong bombardment, and China's activities in the Senkaku/Diaoyu island areas--has served as the witnesses to China's assertive diplomacy in 2010. The major causes of China's assertive diplomacy can be summed up by three factors: potential power transition from U.S. to China; emerging China's nationalism; and the recession of the Tao Guang Yang Hui as a diplomatic principle. But a majority of Western sinologists claim that China's assertive diplomacy is defensive in terms of its character. China's neighboring states, however, perceive its assertive diplomacy as diplomatic threat. Due to these states' geographical proximity and capability gaps with China, these neighbors experience difficulties in coping with China's behavior. In particular, China's coercive economic diplomacy, in which China tends to manipulate the neighbors' economic dependency on China for its diplomatic leverage, is a case in point for China's assertive diplomacy. China's assertiveness seems to be continued even after the inauguration of Xi Jinping government. Although the Xi government's diplomatic rhetorics in "New Type of Great Power Relationship" and the "Convention for Neighboring States Policy" sound friendly and cooperative, its subsequent behavior, like unilateral announcement of Chinese Air Defense Identification Zone (CADIZ), does not conform with its rhetoric. Overall, China's assertiveness has been consolidated as a fashion of its diplomacy, and it is likely to continue in its relations with neighbors. As a neighboring state, the ROK should approach to it with more balanced attitude. In addition, it needs to find out a new diplomatic leverage to deal with China in accordance with its security environment, in which China plays a growing role.

This paper is designed to make a national strategic concept for the ROK's maritime security and to explore cooperation directions for the ROK Navy and Coast Guard in order to implement the newly-made maritime security strategic concept. As strategy is composed of three main categories(goals, ways, means), the goal of the ROK's maritime security strategy is 'Safe and Affluent Sea' and the way to realize the goal is the principle of cooperative leverage, and the means as tasks to implement the strategic concept are maritime safety, maritime security, and maritime stewardship. The concept of national fleet as used in the US is applied to promoting the cooperation between the ROK Navy and Coast Guard. Thus, under the newly-established maritime security strategic concept along with the national fleet model, followings are suggested as policy proposals for facilitating mutual cooperation between the ROK Navy and Coast Guard in dealing with not only traditional threats but also non-traditional treats at sea and from the sea as well. First, the ROK Navy and Coast Guard has been making efforts to enhance interoperability between the two sea services. However, the mutual cooperations have been focused mainly on areas on operational level rather than policy level. Therefore, the two sea services are recommended to enlarge exchanges and cooperation in policy areas. Second, there are still demands for further cooperation areas between the two sea services in command and communications. The interoperability in C2 between the two needs to be upgraded even to the areas of anti-terrorist activities ar sea, ASUW, ASW, maritime interdiction, etc. Third, mutual comparability between the two needs to be reflected in the maritime forces development to ensure the comparability in UNREP and other logistics areas. Fourth, the standardization of logistical materials and equipments is needed as a way of sustaining operational capability and logistical capacity for the ROK Navy and Coast Guard as well. Fifth, the ROK Navy and Coast Guard are recommended to participate more actively in international maritime cooperation activities such as PASSEX. Sixth, Complementary laws and regulations need further to be revised and to be newly made for collectively managing swiftly maritime accidents and natural disasters at sea.

'무게중심'의 개념은 현재 초등교과영역에서 처음 등장하여 대학의 수학과 물리학, 공학 분야 등 폭넓게 응용되고 있지만 실제 교육은 실생활과 유리된 이론수업의 형태가 대부분이었다. 2013년 '${\bigcirc}{\bigcirc}$대학교 과학영재교육원'에서 영재학생들을 대상으로 '무게중심 확인 융합 프로그램'을 개발하였고, 본 연구에서는 이 프로그램을 수준별 수업으로 재구성하여 비영재학생들에게 적용시켜 그 효과성을 분석하고자 한다. 물체의 빈 공간이나 물체 밖에 무게중심이 존재하는 경우를 확인하는 실험 등 새로운 과정을 포함하였으며, 무게중심을 구할 때 핵심이 되는 지렛대의 원리에서 지렛대의 무게를 고려한 계산 방식을 제시하여 보다 실제적으로 개념에 다가갈 수 있도록 하였다. 초 중 고등학교 학생 총 65명을 대상으로 기존 8차시 프로그램을 4차시로 재편성하여 적용하였고, 수업 후 설문과 토론, 인터뷰 등을 통하여 분석한 결과, 학생들은 정밀한 오차분석 등의 과정을 통하여 수준 높은 성공의 경험을 하였다.

본 연구논문의 주제는 기업 인수합병 분야인 차입매수(LBO)에 대한 법제도적 그리고 재무적 응용가능성에 관한 연구이다. 현재 기준, 동 연구주제에 대하여 법제도적인 측면에서는 다수의 국내외 연구들이 진행되어 왔다고 판단되지만, 상대적으로 동 법제도적 측면과 이에 필연적으로 연관되는 재무이론적인 측면에서의 동 금융구조에 대한 분석은 연구결과가 소수라고 판단된다. 본 논문에서는 국내법 판례와 법 해석적인 측면과 함께, 재무관리분야 중 LBO 금융구조와 관련되는 기업재무(Corporate Finance)의 주된 연구방법인 실증적 또는/그리고 이론적인 연구결과를 상호연결 분석한, '학제(Interdisciplinary Study)간 연구'를 수행하기 위함이 본 연구수행의 동기이다. 연구목적과 관련하여, 선진금융구조 또는 금융상품들에 대한 국내 투자자들의 이해제고를 통하여, 법제도뿐만 아니라 재무적인 측면에서의 인식부족 가능성을 감소함으로서, 동 금융구조의 선순환적인 이익(시너지효과)을 제고하고자 함이다. 본 연구의 내용과 관련하여 첫째, LBO 금융구조에 대한 개념과 구조에 대한 분석, 법제도 측면에서의 국내의 최근까지 주요 판례들에 대한 사전분석(즉, 담보제공형 LBO와 합병형 LBO), 그리고 재무적인 측면에서의 기존의 LBO 구조와 관계되는 인수합병(M&A) 연구결과 분석과 요약 등을 서술하였다. 특히, 동 금융구조 활용 시 주된 이슈가 되는 대상회사(피인수법인) 임원진의 '주의의무'와 '충실의무'의 관련내용을 분석하였고, 추가적으로 '경영판단의 원칙'상 면책가능 범위에 대한 법해석상의 향후 실무적 응용가능성을 위하여 그에 관한 재무적인 측면에서의 이론적 분석도 수행하였다.
