This paper presents a new type of fuzzy logic-based power control strategy for fuel cell hybrid electric vehicles designed to improve their fuel economy while maintaining the battery's state of charge. Since fuel cell systems have inherent limitations, such as a slow response time and low fuel efficiency, especially in the low power region, a battery system is typically used to assist them. To maximize the advantages of this hybrid type of configuration, a power distribution control strategy is required for the two power sources: the fuel cell system and the battery system. The required fuel cell power is procured using fuzzy rules based on the vehicle driving status and the battery status. In order to show the validity and effectiveness of the proposed power control strategy, simulations are performed using a mid-size vehicle for three types of standard drive cycle. First, the fuzzy logic-based power control strategy is shown to improves the fuel economy compared with the static power control strategy. Second, the robustness of the proposed power control strategy is verified against several variations in system parameters.

With the dawn of the 21st century, the corporate business environment started to witness the unprecedented, intense competition on global basis. As a result, the kind of corporate business activity that can respond swiftly to the new changes emerged as one of the most critical factors to increase corporate competitiveness. Being reborn as a strategy-focused organization means seeking innovation. And the strategy not involving innovation is just meaningless. It is this innovation that lies at the heart of the corporate strategy, and that is the only way for continuation of the corporation. The most important pending issue facing companies today is to bolster corporate competencies fit for new business environment, to develop corporate culture required for getting competitiveness edge back, and ultimately to put the company on the continued growth path. Corporate culture, as the very underlying belief and philosophy, is not just woven into the fabric of the corporate management strategy and into the way the company is doing its business. It also, as a regulation and norm for its employees to stick by, affects the way they think and behave. This paper aims at presenting the role of the corporate culture in working out problems encountered by companies today, like corporate innovation, instilling vitality to the organization, beefing up the underlying corporate capabilities, and making transformation required by the changing business environment.

Normative theory suggests that control systems should be designed to complement management's objectives and strategies. However, few empirical studies have focused on how control systems have been modified to complement new manufacturing techniques, such as zero-defect strategy. The major purpose of this study is to examine the effects of the attributes of quality strategy and control system on performance. The previous studies have subdivided quality strategy into the ECL(economic conformance level) and ZD(zero-defect) strategy. To accomplish the purpose, this study empirically analysed the data based on the questionnaires from manufacturing department personnel of 67 Korean companies. The major results are as follows. The companies that had implemented the ZD strategy and its control system outperformed the companies that had implemented ECL strategy. Also, the ZD strategy differs from ECL strategy in control system, the criteria of performance evaluation and feedback frequence variable. There is no difference in quality performance monitoring and communication variable. From this results, although many companies have strived for continuous improvement of quality, it was restricted in improvement activities that dont's required much investment cost, quality performance monitoring and communication.

The processor allocation problem in mesh multicamputers is to recognize and locate a free submesh that can accommodate a request for a submesh of a specified size. An efficient submesh allocation strategy is required for achieving high performance on mesh multicomputers. In this paper, we propose a new best-fit submesh allocation strategy for mesh multicomputers. The proposed strategy maintains and uses a free submesh list to get global information for free submeshes. For an allocation request the proposed strategy tries to allocate a best-fit submesh which causes the least amount of potential processor fragmentation so as to preserve the large free submeshes as many as possible for later requests. For this purpose, we introduce a novel function for quantifying the degree of potential fragmentation of submeshes. The proposed strategy has the complete submesh recognition capability. Extensive simulation is carried out t compare the proposed strategy with the previous strategies and experimental results indicate that the proposed strategy exhibits the best performance along with about 10% to 30% average improvement over the best previous strategy.

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 object of this study is to present a strategy against technology protectionism of advanced countries focusing on international cooperation policy of KIPO and infringement of overseas intellectual property rights on the notion that a policy performed without a long-term plan will not lead to industrial growth in the long run. There is a high possibility that aggressive patent policy and black box strategy of Japanese enterprise can be a burden to Korean enterprises. Thus, a policy should be established against the technology protectionism. The policy can be based on a strategy about international cooperation policy of KIPO and strategy against infringement of overseas intellectual property rights. Of course, collaboration and cooperation will be activated among the advanced countries including technical cooperation. However, a systematic strategy of intellectual property rights should be focused on international cooperation and countermeasure against infringement of overseas intellectual property rights because national interest takes precedence over any other interest especially in case of strategically owing industry. A strategy against technology protectionism of advanced countries is as follows. A strategy is required to cope with infringement of overseas intellectual property rights. Korean government has to strengthen the function of overseas intellectual property rights protection center, strengthen boundary restriction of infringement goods, promote international dispute study, train international dispute specialist, construct confidence as social capital etc. Enterprises have to maintain no Patent no Future policy, specialize on application and countermeasure against infringement dispute, participate for formation and standardization of patent pool, strive for specialization regarding technical transfer and license management.

In this paper, we have developed an hourly operating strategy for Direct load control (DLC) considering the efficiency of DLC program and increasing the utility of DLC resource. According to the operating code for DLC, the DLC center should curtail the load for 4 hours when the control notification has been enforced. Since the above strategy may limit the participation of entities, who intend to take part in the DLC program, the new strategy to mitigate the above limitation is required. In this paper, we have developed the operating strategy of DLC program and the mechanism to apply the proposed strategy in the DLC center. The proposed strategy makes the important role from the view of guaranteing the effective alternative raising the participation and avoiding the penalty of the entities.
