본 연구의 목적은 서남해안 갯벌의 보호 및 관리 체계 모델을 제시함으로써 세계유산 신청을 위한 효율적인 보호 및 관리 체계를 구축하는데 있다. 서남해안 갯벌은 유네스코 세계유산에서 강조하고 있는 탁월한 보편적 가치에 대한 잠재적 가능성을 가지고 있다고 판단된다. 서남해안의 갯벌이 세계유산으로 등재되어 체계적으로 관리된다면 자연자원의 현명한 사용(wise use)을 통한 인간과 자연의 조화에 의해 전 세계 모든 인류가 지향해야할 지속가능한 발전을 이룩하는 대표적인 모범 사례가 될 수 있을 것이다. 이러한 관점에서 현재 서남해안 갯벌 대상지역의 보호 및 관리체계를 조사하고, 해외 유사 유산의 관리 사례 조사를 통해 서남해안 갯벌의 관리방향과 체계를 위한 현재의 관리정책을 수정하고 보완사항을 도출하여 우리의 실정에 맞는 모델을 제시하는 것은 세계유산 등재 추진을 위해 반드시 필요한 일이다. 서남해안 갯벌에 해당되는 전체 잠정목록 대상지에 대한 조사 결과, 세계유산의 보호를 위한 합리적인 관리체계를 개발하기 위해서는 보호지역의 추가 지정 및 확대가 필요한 상태이다. 또한 현재의 관리체계는 등재 추진부서(예 : 문화관광과)와 실제 갯벌 관리부서(예 : 해양수산과)로 이원화되어 있다는 문제점이 있다. 이러한 관리부서의 이원화는 세계유산을 합리적으로 추진하기 위한 중장기적인 관리계획을 수립하고 단위사업을 수행하고, 또한 향후 세계유산을 효율적으로 관리하기에 상당한 문제를 야기할 수 있다. 따라서 서남해안 갯벌의 세계유산 등재를 위해서는 보호지역의 확대와 지자체별 이원화된 관리체계의 통합, 그리고 중장기적 통합관리 계획을 수립하는 것이 필요하다. 이를 위해서는 서남해안 갯벌의 효율적이고 지속가능한 보호 및 관리를 위한 관 학 민 NGOs 등 다양한 이해 당사자들의 통합을 위한 협업체계를 구축하는 것이 필수적이다. 즉, 와덴해의 사례와 같이 민관산학의 협의체를 구성하여 유산의 보호 및 관리의 핵심주체인 지역주민의 토착지식과 의견을 기반으로 다양한 이해 당사자들의 의견을 모아, 이를 지역 또는 국가의 정책으로 입안하여 채택하는 상향식 구조를 갖는 것이 필요하다. 중장기적 관점의 통합계획에 있어서는 서남해안 갯벌의 자연 문화유산 보전 및 관리 통합계획 '서남해안 갯벌의 자연과 문화유산 보전 및 관리 통합계획(Integrated Plan for Conservation and Management on Natural and Cultural Heritages in Southwestern Coast Tidal Flat)'의 수립을 제안한다.

We isolated and examined a new Alternaria sp., which causes leaf spots on Peucedanum japonicum in Korea, by using molecular and morphological methods. Phylogenetic analysis based on a combined internal transcribed spacer region analysis and two protein-coding genes (gpd and Alt a1) demonstrated that the causal fungus was most closely related to A. cinerariae and A. sonchi, and relevant to A. brassicae. However, conidial morphology indicated that it is a novel species within the genus Alternaria, and therefore we have assigned the fungus a new name in this study.

These days, as the usage of explosive gas is increased, the demand of safety of explosive gas is increased. As a suggestion of protection against the explosive gas, the research on application of fiber-reinforced concrete has been conducted. In this research, therefore, to evaluate the constructability of anti-explosive concrete, the engineering properties of the FRC after pumping is studied.

The main objective of this study is to analyze the preservation and management for the city wall ruins of China, and to find out the implications. Firstly, Chinese walls have experienced a process from demolition to protection. The walls of the historical value of the site are gradually being certified, and many walls ruins were designated as a conservation unit. Secondly, China's institutional system is based on the central government issued Cultural Relics P rotection Law and combined with the actual situation of local governments to establish a special law. Management System is Cultural Relics Bureau, the planning department, the garden department and the tourism sector joint implementation. Thirdly, through the study of Nanjing, Xian, Pingyao, Suzhou city wall ruins finding that perfect legislation and unified management system to help protect city wall ruins.

This paper analyzes overvoltage on testing line for various parameter effect examination. Model systems consist of overhead line and underground cable. The model considered actual characteristic data of distribution lines. and will be constructed at testing yard. The simulations were performed under various line configuration such as cable kinds, cable length, lightning wave, lightning wave time, transformer and branch circuits. The simulation models are established by EMTP/ATPDraw and Line Constants are calculated by ATP_LCC. When lightning surge strikes on conductor of overhead line, EMTP/ATPDraw calculates overvoltage in many cases. Simulation results will be compared with real testing results at testing yard. The compared results will be used to establish protection methods in actual underground distribution systems.

This paper describes a current differential relaying algorithm for power transformers with an advanced compensation algorithm for the secondary current of CTs. The comparative study was conducted with and without the compensating algorithm. The algorithm can reduce the operating time of the relay in the case of an internal fault and improve security for external faults. The performance of the proposed algorithm was investigated when the C100 CT, a quarter of the rated CT(C400), is used.

As the importance of recycled materials is being emphasized more in the Korean construction market, the production quality has been improved to a significantly high level. Compared to the high quality, however, there are used very limitedly. Among recycled construction materials, recycled aggregates produced through the retreatment of waste concrete are drawing attention because of lack of natural aggregate and heightened consciousness of resource saving and environmental protection and, as a consequence, they are close to natural aggregates in terms of production technology and quality. Despite the high quality and productivity, however,. the utilization of recycled aggregates is very low. Thus, in order to maximize the utility of recycled aggregates, the present study examined the usability of recycled aggregates using both recycled coarse aggregates and recycled fine aggregates together and derived optimal quantity and mixture ratio in the combined use of the two types of recycled aggregate.

Improving intraoperative and postoperative myocardial protection and better construction and design of valvular prosthesis has reduced the mortality of MVR. But, ventricular rupture after MVR occurred occasionally and represented a potentially lethal complication. Transverse midventricular disruption presented as refractory myocardial failure immediately on termination of bypass or later often on initial period of good hemadynamics. From Jan., 1985 through Dec., 1991 131 MVRs were performed as isolated or combined procedures. Rupture of the posterior wall of left ventricle was observed in 2 patients. There were 2 type III ruptures Prevention is of utmost importance, and by taking certain precautions, the chance of ventricular rupture can be reduced. Repair should always be done by patch technique in the aid of the use of cardiopulmonary bypass with cardioplegic arrest. When the laceration is in the middle of the posterior left ventricle, external repair with the pericardial patch can be attempted first.

Genetic diversity of 21 Korean Phytophthora capsici isolates was analyzed by using several molecular markers such as random amplified polymorphic DNA(RAPD), M-13, microsatellite and random amplified microsatellite sequences(RAMS). The overall average similarity coefficient among the isolates was 86% based on the combined data obtained by the molecular markers. No molecular markers were found to be associated with hosts or geographic regions. In addition to RAPD, analysis based on repeated sequences such as $(GTG)_5$, M-13 and RAMS could be used to assess population structure of P. capsici.
