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.

This study is aimed to find out which factors among firm-specific resources, industry-based competition, and institutional conditions affect strategies for Korean IT manufacturing companies when they expand their business overseas, especially to Vietnam in this study. Also, it attempts to reveal which strategies among cost reduction, mass production, and localization affect performance of overseas expansion. Based on Strategy Tripod Theory as an integrating point-of-view embracing resource-based view, industry-based view, and institution-based view, research model was developed and tested through the survey of 83 Korean IT manufacturing companies expanded their business to Vietnam. Research findings show that (1) communication competency, industry competitiveness, industry attractiveness, and regulation of partner country affect cost reduction strategy. (2) International experience, communication competency, international orientation, and competitiveness is significantly associated with mass production strategy. (3) And international experience, communication competency, and industry competitiveness affect localization. (4) Ultimately, mass production strategy and localization strategy significantly increase performance of expansion to Vietnam. The theoretical contribution of this study is to adopt an integrative approach based on strategy tripod theory. As practical implications, it suggests factors and strategies that IT manufacturing companies interested in expansion to Vietnam should consider. In sum, we believe this study can contribute to Korean IT manufacturing industry by suggesting key success factors and appropriate strategies for overseas expansion.

Situational Crisis communication theory (SCCT), one of the major crisis communication theories, suggests that crisis managers have to choose the most effective crisis response strategy in accordance to the crisis type. However, there's a controversy over whether this theory is practically applicable in Korea. Therefore, this study analyzed statements of apology to see if companies in Korea are actually taking different response strategy according to the types of crisis. According to the result of analysis on 244 apology statements published in the newspapers from 2012 to spring of 2015, adaptive response strategy was mostly taken no matter what the crisis type was. In conclusion, there's a discrepancy in crisis response strategy between the theory suggested in SCCT and the current practices in Korea. This conclusion can contribute to devising an appropriate application of SCCT in Korea and to develop a more Korea relevant theory.

This study designed and developed a class using review games as a way to enhance students' interest, class participation, and class comprehension in engineering theory classes, and explored their educational effectiveness. To this end, a review game strategy based on the Creative Training Technique was established and applied to three engineering theory subjects. The types of review games include Jin-jin-ga, Bingo, Challenge Golden Bell, Finding hidden terms, and Completing initial sentences. As a result of applying this review game strategy to the classes over the past decade, students' satisfaction and lecture evaluation scores significantly increased compared to before application, and it was confirmed that students' interest in and understanding of the class increased significantly. Furthermore, this gamification class strategy can be a way to increase students' participation in theory classes regardless of their major, and can be applied to non-face-to-face online classes.
