As one of the most popular outdoor leisure activities in the world, recreational fishing has a lof of significant meaning in terms of social, economic, and cultural views. However, both not considering an indiscreet fishing activity and environment and not thinking our next generation, fishing circumstance has been deteriorating more and more. Unlike Korea, most advanced countries enact various recreational fishing management and support policies in order to keep sustainable recreational fishing and develop eco-tourism through cooperation with government, fishing industries and civil organizations. This paper consist of the following contents. First, the study attempted to investigate how to operate management system of the recreational fishing dividing into in - land fishing and sea fishing respectively. And it exhibits issues and troubles of the realities of recreational fishing management and related fishing laws and ordinances in Korea. And then, it examines various fishing management schemes in representative advanced nations; U.S., Germany, and Japan. Also, it analyzes the advantages and disadvantages of respective recreational fishing management systems; market - based license system, qualification - based management system, and self- regulatory based management system. In addition, after these three systems are adopted to Korea's recreational fishing condition, we analyzes whether respective management systems fit or not. As a result of this, the optimal management for recreational fishing is the participatory self - management scheme in Korea. Finally, in order to support recreational fishing promotion and encouragement, issues and complementary policies with respect to recreational fishing are introduced.

In this research, we report on the development of simulation system for performance verification of BMS(Battery Management System) which is utilized in electric vehicles. In the industrial circles, a manufacturer of BMS typically tests their system with real battery packs. However, it takes a long time to test all functions of BMS. Here, we develop BMU(Battery Managament Unit) as an embedded board, which will be installed in electric vehicle for controlling battery packs. All other environment factors for testing BMU are developed in softwares in order to reduce the term of test. Especially, the proposed system consists of cell simulator and CMU(Cell Management Unit) simulator which simulate real battery cells and control battery cells. These simulators enable the BMU to test more battery cells. In addition, proposed system provides diagnosis program in order to diagnose and monitor the condition of BMS which makes the test of BMS more easily. In order to verify the performance of the developed simulator, we have performed the experiment with real battery packs and our simulator. Through comparing two results of experiments, we verify that developed simulator shows better performance in terms of less amount of testing duration though having high reliability.

This paper describes a web-based design review system as a knowledge management system relating reliability and safety system design. Since people's consciousness for safety and security become sensitive and increases the need of establishing a proactive prevention method for internal failures and relating risks in products. It also means that prevailing tacit knowledge in retired workers, in order to transform them to be easily used to support new system development, become more important. When considering safety and reliability design, at least two data sheet are necessary; Failure Modes and Effects Analyses (FMEA) and Risk Assessment (RA). These two data are practically made separately. However, it includes the concerns that a risk by failures during long-term use may not be noticed. To overcome this insufficiency, a support tool for integrating reliability evaluation and risk assessment data simultaneously is expected to be revealed. The authors have then developed a web-based design review system for reliability and safety system design. The system include various profitable functions; making FMEA and RA sheet, retrieving past data sheet for engineering change management and new product development and web-based discussion to increase the efficiency of discussion. The system is applied to one practical development works in order to demonstrate its effectiveness that is to be made clear by interviewing user's qualitative comment.
