The existing Law of fisheries Management of China was firstly established on October 30th, 1986 and revised in October, 2000. The new Law of Fisheries Management provided a basis for introduction of the TAC (total allowable catch) system into China. Introduction of the TAC system is a natural result of the practise of EEZ (exclusive economic zone). In addition, the inability of the traditional fishery management system and the promising results obtained by conductions of TAC system in some countries with advanced fishery also make the introduction of TAC system a necessity, However, the contradictions between the unrealistic introduction of the fisheries management systems, the small-scale operation, higher expense of the conduction and supervision of the systems, and the insufficiencies of human power, financial fund, and scientific technique of the underdeveloped country resulted in the ineffectiveness of the new systems. So this study is to discuss the background and the possibility of TAC system implementation in china. The results of this study showed that many factors restrict the implementation of TAC system into China at present. It will take a long time to practise the new system. meanwhile, reforming and improving the functions of the existing systems to provide a better environment will play an important role in the introduction of the TAC system into china.

Increasing number of corporations applies IT service management systems to optimize IT service delivery and support processes. For this reason, implementation experiences and effect of IT service management system are growing concerns for IT managers and researchers. This case study analyzes implementation experiences on an ITIL based service management systems in an medium sized corporation. The exploratory case analysis revealed that systems and service quality were improved from the implementation. This study will contribute to the successful implementation of IT service management system and developing a research model of IT service management process.

The purpose of this study is to illuminate the reason why community building policies by the Government seem to fail to work properly in Korea. The existing studies focus mainly on designing community building systems, thus they cannot provide plausible explanations about the cause of the unsuccessful outcomes from the policies. To overcome the limitations of the existing studies, the authors examine the implementation factors to influence the policy instruments with the perspective of policy implementation. By performing the analysis, the results imply the implementation factors, such as executer's competence, supports by related interests, incentive systems, and legal-institutional instruments, are important to influence the implementation performance of the relevant policy instruments. To make community building successful policies, The authors therefore suggest that the capacity of local administrators and residents should be raise, and one of which the way to enhance is to support research and program development by the resident-oriented living laboratory systems in localities.

The purpose of this study, based on a domestic sample of businesses using EDI systems, is to identify success factors, which affect the implementation of EDI system by Korean business entities. This paper also intends to provide useful guidelines for the establishment and management of EDI systems. This paper, first, develops a conceptual framework based on pervious research to identify factors which affect successful implementation of EDI system. Second, it integrates the constructs from previous research studies into a single survey instrument. Third, it presents the findings regarding the degree to which each factor influences the successful implementation of EDI system. It's revealed in the study that such factors as EDI vendor support, EDI education and training, participation by transactional partners, the size of organization, and the level of decentralization among organizational and environmental characteristics influence successful implementation of EDI systems in Korean business environment.

This research has seven factors such as top management leadership, belt system operation, implementation of systematic methods, adequate project performance measurement, customer focus performance, quality performance and business performance. Those are critical to correct implementation of Six Sigma. I set seven hypotheses which represented the relationships among the seven factors, gathered questionnaires and analyzed the data. Top management leadership affected positively the adequate project performance measurement and the belt system operation, The belt system operation affected the implementation of systematic methods positively and it also affected the adequate project performance measurement. It affected positively the customer focus performance, the quality performance and the business performance, respectively.

The single carrier frequency domain equalization (SC-FDE) technology is an important part of the broadband wireless access communication system, which can effectively combat the frequency selective fading in the wireless channel. In SC-FDE communication system, the accuracy of timing synchronization directly affects the performance of the SC-FDE system. In this paper, on the basis of Schmidl timing synchronization algorithm a timing synchronization algorithm suitable for FPGA (field programmable gate array) implementation is proposed. In the FPGA implementation of the timing synchronization algorithm, the sliding window accumulation, quantization processing and amplitude reduction techniques are adopted to reduce the complexity in the implementation of FPGA. The simulation results show that the algorithm can effectively realize the timing synchronization function under the condition of reducing computational complexity and hardware overhead.

System management application system is one of the most interesting fields in Ubiquitous Sensor Networks. It conforms to the property of Ubiquitous Sensor Networks very well, and it is the closest application for commercial use. We have two kinds of system management technology, such as the one which is accessed by web browser at anytime, anywhere and another one which is for local accessed system. In this paper, our purpose is implementation of system management application system which provides Mesh Sensor Networks topology with IP based agent platform and system management server. Furthermore we introduce the functions used for our recent implementation and propose several future issues about system management application system.
