The purpose of this study is to find out a significant influence of continental strategy theories on the development of maritime strategy theories. For this purpose, I examined similar and different parts of each theories and their implications when applied to different environment. In details, Chapter 2 deals with how continental strategy and maritime strategy theories are similar and different in general. In Chapter 3, I look into how Karl Clausewitz's theory that has been quoted the most by military strategy theorists had influenced over the theory of Julian Corbett, one of the representative English maritime strategy theorists. In Chapter 4, I study how the theory of Alfred Mahan that has also been quoted the most among the theories of maritime strategy had been influenced by Antoine-Henri Jomini's theory. And in Chapter 5, their contemporary implications and conclusions are drawn. According to my findings, unbelievably, the theories of maritime strategy had been influenced by existing continental strategy theories very much. Many similarities are found between them. However, at the same time, a large part of them is found significantly different from original ones especially when used to reflect the maritime distinctiveness. This means that the past maritime strategy theories and stored experience also wield influence, in many ways, yielding out much better ones in terms of applicability to changing environment. Therefore, devising new strategies with creative attitude using knowledges and experiences from both other fields and past ones is the virtue required for maritime strategists.

The change of any element in the network is possible to cause performance degradation of the multicast network. So it is necessary to optimize the topology path through the multicast update strategy, which directly affects the performance and user experience of the overlay multicast. In view of the above, a new multicast tree update strategy based on perturbation theory Musp (Multicast Update Strategy based on Perturbation theory) is proposed, which reduces the data transmission interruption caused by the multicast tree update and improves user experiences. According to the multicast tree's elements performance and the topology structure, the Musp strategy defines the multicast metric matrix and based on the matrix perturbation theory it also defines the multicast fluctuation factor. Besides it also demonstrates the calculability of the multicast fluctuation factor presents the steps of the Musp algorithm and calculates the complexity. The experimental results show that compared with other update strategies, as for the sensitivity of the multicast fluctuation factor's energized multicast tree to the network disturbance, the maximum delay of the Musp update strategy is minimal in the case of the local degradation of network performance.

The existing defense strategy selection methods based on game theory basically select the optimal defense strategy in the form of mixed strategy. However, it is hard for network managers to understand and implement the defense strategy in this way. To address this problem, we constructed the incomplete information stochastic game model for the dynamic analysis to predict multi-stage attack-defense process by combining Bayesian game theory and the Markov decision-making method. In addition, the payoffs are quantified from the impact value of attack-defense actions. Based on previous statements, we designed an optimal defense strategy selection method. The optimal defense strategy is selected, which regards defense effectiveness as the criterion. The proposed method is feasibly verified via a representative experiment. Compared to the classical strategy selection methods based on the game theory, the proposed method can select the optimal strategy of the multi-stage attack-defense process in the form of pure strategy, which has been proved more operable than the compared ones.

Many of Korea major companies have appled as strategy of management innovation Six Sigma, Lean and Theory of Constraints. Six Sigma has mainly focused to reduce variation. Lean has mainly focused to reduce wastes and Theory of Constraints has mainly focused that bottleneck of constrains production and sales. This bottleneck is caused by constraint resources and it should be the main role of manager to explore constraint resource. Although their mainly focus are different, they are used to improve productivity and quality. In this paper, as strategy of management innovation, study on analysis and comparison plan of Six Sigma, Lean and Theory of Constraints. From the literature survey and application cases, it is suggested and discussed that how to plan of application as strategy of management innovation successfully. The suggested plan of application could be a good guideline that it could be a apply of companies.

Purpose: This study was to understand to the nursing theory frame contained in the traditional philosophy and western nursing theory for the theory development fit for Korean people and to identified the strategy for nursing theory development. Method: To perform this study various relevant texts-western, eastern, classical and contemporary were reviewed. Result: The metaparadigm of the nursing in western considers four major factors-Human being, Environment, Health and Nursing. In Korea, the metaparadigm of nursing considers three major factors-Universe, Human being (body, life, health, disease) and Nursing. The key strategy for establishing comprehensive nursing theory which combines both western and eastern is to study the nursing literature based on eastern and western philosophy. Theorists should study the life and culture of the specific nation in order to understand the essence of the thoughts and psychology of the patients and to investigate the phenomena, which will be the foundation of theory development. Conclusion: Western nursing theory must be utilized to provide practical framework for the development of nursing theory, and practical approach is necessary for combining western and eastern theory.

To establish an effective security strategy, business enterprises need a security benchmarking tool. The strategy helps to lessen an impact and a damage in any threat. This study analyses many aspects of information security management and suggests a way to deal with security investments by considering important factors that affect security manager's decision. To address the different threats resulting from a major cause of accidents inside an enterprise, we investigate an approach that followed ISO17799. We unfold a criminology theory that has designated many measures against the threat as suggested by General Deterrence Theory. The study proposes a coherent model of the theory to improve the security measures especially in handling and protecting company assets and human lives as well.

기업의 위기 관리에 관한 주요 PR 이론 중 하나인 상황적 위기커뮤니케이션 이론에서는 위기 유형에 적합한 위기 관리 대응 전략을 사용할 것을 주장하고 있다. 주로 기업의 책임이 높은 경우에는 순응적 전략을 사용하는 것이 유리하고, 기업의 책임이 낮은 경우에는 대응적 전략을 사용하는 것이 적합하다고 본다. 그런데 이러한 이론이 한국에서도 실제 적용되고 있는지에 대해서는 논의가 존재한다. 따라서 본 연구에서는 실제 기업이 위기 관리 유형에 따라 차별화되는 위기 대응 전략을 사용하고 있는지 여부를 살펴보고자 하였다. 2012년부터 2015년 봄까지 언론 등에 발표된 사과문 224개를 분석한 결과, 한국에서는 일단 모든 경우에 사과, 개선 등 순응적 전략이 많이 사용되었다. 결론적으로, 상황적 위기 커뮤니케이션 이론에서 제시하는 위기별 대응 전략과 한국에서 이루어지는 위기별 실제 대응 전략 간에는 차별성이 존재했다. 한국에서는 기업의 책임 여부에 상관없이 사과 등이 일반적으로 사용되는 대응 전략이었으며, 회사 대표가 전면으로 나서는 경우도 위기 유형별로 다른 특성을 보이고 있었다. 이러한 결론은 한국에서의 상황적 위기 커뮤니케이션 적용과 이론 개발에 기여할 수 있을 것이다.
