The Yellow Sea and the East China Sea are the most important fishing grounds for the fishing industry of Korea, China and Japan which are major coastal states of these Seas. But the fishery resources in these fishing grounds are almost exhausted and also the sea region is seriously polluted. Accordingly an international joint countermeasure is necessary to recover the fishery resources and to keep the fishery a continuous industry. The authors inspected the existing fishery policies and international fishery relationship of the three coastal states, and suggested rational conservation and management regime of the fishery resources in these sea regions. 1. At present the legal status of the sea region beyond territorial sea is the high sea, for that reason the international cooperation is urgently needed to establish common regime for conservation and management of the fishery resources. 2. A series of scientific research on ecological system of fishery resources must be carried out in the sea region first of all for that purpose. 3. The existing Korea-Japanese Fishery Agreement and Sino-Japanese Fishery Agreement should be reformed to coincide with the new legal order of the UNLOS Convention, and the Sino-Korean Fishery Agreement should be concluded newly on the identical line. 4. As a conclusion, a joint conservation and management regime through a regional fishery organization or a individual conservation and management regime through the promulgation of exclusive economic zone by each state can be suggested to resolve the fishery resources conservation problem in the Yellow Sea and the East China Sea.

The Section 12 of Groundwater Law stipulates that groundwater conservation zone should be regulated by the designation of conservation area and development restricted area, The most important policy for groundwater conservation and protection is to estimate and designate groundwater conservation zone. The groundwater classification map is utilized to determine the prime groundwater conservation areas, which delineate the first and the second ranked conservation areas of the map. According to the classification method of the Ministry of Construction and Transportation in 2000, groundwater quality for groundwater classification is classified with 4 levels based on the following conditions : (1) the present groundwater quality; (2) the potential usage as drinking water at present and in the future; (3) hydrogeological characteristics, and (4) the existence of pollution sources and activities. Throughout the initial analysis, the groundwater conservation areas are represented about 57.1$\textrm{km}^2$ in the groundwater classification map, which is 9.4% of Seoul Metropolitan Area. The management guidelines for groundwater conservation area are also developed referring to Cheju Province Groundwater Conservation Management Project and the guidelines by the Ministry of Construction and Transportation. But the specific administration and detailed technical survey should be prepared to efficiently manage the groundwater conservation area.

Recently, the recognition is changing about cultural heritage, and the various types of buildings or facilities of modern or contemporary times have been designated as cultural properties after that Registered Cultural Properties System is enforced. The purpose of this study is to survey how the newly born the historic buildings of modern or contemporary times through the remodeling process of the Studio 'Byeol'(the Training Center for Performers of Korean Traditional Music) in the National Theater of Korea so-called a microcosm of performing arts history. In the process, it will examine the merits and demerits of various alternatives and the direction of the remodeling etc., and propose an utilization as a basic data of post evaluation for the remodeling of a historic building. The result are as followings. Firstly, the remodeling that gave a new physical properties to a building can be used a method of conservation and reuse on a historic building. The remodeling of a historic building must be eclectically progress between the owner and the citizen or the economic value and the historicity conservation. And, the remodeling of historic buildings such as the Training Center for Performers of Korean Traditional Music must consider the conservation of the exterior walls in whole or in part at least. Secondly, an architect Lee Hee Tae(李喜泰) who had been to develop his own architectural vocabulary and to test based on the korean traditional architecture and the Training Center for Performers of Korean Traditional Music must be newly evaluated today. Lastly, the remodeling alternatives of the Training Center for Performers of Korean Traditional Music have been analyzed with three types, which is 'repairing only the interior which maintains the size and an appearance of present', 'extending the outer wall to the external column line', 'extending the basement'. And, it was analyzed with the appropriate final decision that it remodels only the interior in the current situation because of a historicity, a budget, a relevant law etc.

Population genetic assessment is essential for the conservation and management of endangered and rare plants. Neofinetia falcata is endangered epiphyte orchid and protected by law in Korea. In Korea, this species is only found on islands in the South Sea of Korea (including Jeju-do) and the southern coast of the Korean Peninsula. We developed nine microsatellite makers to assess the genetic diversity and population genetic structure of three populations of N. falcata. The genetic diversity at the species level was low, which can be attributed to inbreeding or fragmentation into small, isolated populations. A recent bottleneck was detected in one population, likely due to overcollection. N. falcata exhibited moderated levels of differentiation among populations, with the three populations were divided into two clusters based on genetic structure. The genetic diversity and structure of N. falcata are affected by restricted gene flow by pollen or seeds due to isolation and geographic distance. Strategies for in situ and ex situ conservation of this species are been proposed based on the results of our study.

A meshless technique using the geometric conservation least-squares method (GC-LSM) was devised to discretize the governing equation of linear elasticity. Although the finite-element method is widely used for structural analysis, a meshless method was developed because of its advantages in a moving grid system. This work is the preliminary phase for developing a fully meshless-based fluid-structure interaction solver. In this study, Cauchy's momentum equation was discretized in strong form using GC-LSM for the structural domain, and the Newmark beta method was used for time integration. The solver was validated in 1D, 2D, and 3D benchmarking problems. Static and dynamic results were obtained. The results are more accurate than those of analytic solutions.

Among Korea's national folk cultural heritage, eight villages have been designated, and 37 years have passed since Hahoe Village was first designated in 1984. All eight villages have been constantly inhabited by residents from the past to the present, so the cultural value of inferring the lives of our ancestors in the past is very high. However, due to the inconvenience of the settlement environment in existing houses due to changes in the living environment, buildings such as various residential facilities and warehouses have been installed and expanded without permission, losing the original cultural property landscape and building. In addition, complaints and conflicts from residents are accumulating due to the poor living environment in the village. Therefore, this study intends to present guidelines for conservation and maintenance that can embrace changes in resident's housing and living environment, based on the 'maintenance of original form', the grand principle of the Cultural Properties Protection Law about the Jeju Seongeup Village. In particular, the maintenance plan is largely subdivided into legalization, demolition, expansion and reconstruction, and detailed standards for each item and examples applied are proposed. Through this, it aims to become basic data on the starting point of realistic improvement measures for cultural properties and residents to coexist.

This study intends to suggest the improvements for the legal systems related to the conservation of mountain ridge areas. The 4 legal systems directly related to the conservation of mountain ridge areas are reviewed and the current conditions of adaptive reuse of mountain areas and destroy cases in Hwasung are examined. For solving the problems on the basis of the analysis, three proposals for the improvement on legal systems are suggested. First, the integration of present dual legal systems related to adaptive reuse of mountain areas on the assumption that the related criteria and provisions should be amended, second, activation of the legal systems such as natural landscape district and natural landscape review to make up for the laws related to adaptive reuse of mountain areas, third, the enactment and application of the ordinances related with the 'mountain area management law'.

In this study, reduced-scale experiments as the alternative to a real-scale fire test were conducted to understand fire properties in atrium space. The scaling laws were derived from $\pi$-parameters which were deduced by dimensional analysis of governing equations (continuity, conservation of momentum and conservation energy). The 1/50 scale experiment simulated the real-scale fire test in SIVANS atrium at Japan were conducted under the scaling laws. And this results were compared with real-scale experiment results. Furthermore these results were visualized by video recording system using laser light sheet.

Reynolds equation, which describes behavior of fluid film in journal bearings, basically satisfies mass conservation. But, boundary conditions usually used with this equation, e.g. half Sommerfeld or Reynolds boundary conditions, cannot fulfill this natural law of conservation. In the case of connecting rod bearing, where applied load is dynamic and its magnitude is relatively large, such unrealistic boundary conditions have serious influence on calculation results, especially on lubricant flow rate or power disspation which are important parameters in thermal analysis. In this paper, mass-conserving boundary condition was applied in the finite element analysis of connecting rod bearings. Lubricant flow rate and power dissipation rate were calculated together with journal center locus, minimum film thickness and maxmium film pressure. These computation results were compared with those of the case of Reynolds boundary condition. Balance between inlet and outlet flow rate was well achieved in the case of mass-conserving boundary condition.
