The purpose of this study are to develop a SDSS (Spatial Decision Support System) that can incorporate diverse opinions of stakeholders related the designation of protected areas (PA), and to employ the model for the readjustment of the boundary line of the Jirisan National Park of Korea. The SDSS would lead to more rational and less controversial decision-making during the expansion or removal of PA in Korea. Research methods are as follows. Firstly, to select evaluation criteria for SDSS for PA designation by using expert interview and literature survey. Secondly, to measure their preferences on the designation of additional PA or the removal of a part of PA based on the opinions of various stakeholders such as local residents, environmental groups, or public officials. Thirdly, to produce conservation priority maps based on a multi-criteria decision making technique. The SDSS would be used to rational decision making for the expansion of PA or the release of a certain part of PA by reflecting diverse preferences on biodiversity conservation and economic interest of residents. The visualization of conservation priority maps would also increase the efficiency of such decision making processes. The evaluation criteria for the expansion of PA for biodiversity conservation includes vegetation conservation value, wildlife conservation value, and the habitats of key species. The evaluation criteria for the removal of PA includes the proximity to roads and the boundary of PA, land use types, and conservation zoning of the PA. Preference weights are based on data collected from the Jirisan National Park. Both the conservation priority and removal priority maps are based on land parcels so that property rights of all parcels would be correctly represented.

Since 1985, the Ministry of Environment has supported environmental education in schools through Environment Conservation Model School initiative. Selected elementary, middle, high schools and kindergartens were designated as model schools for environment conservation programs every 2 years to develop model cases that can be adopted at other schools to promote more structured and effective environmental education. These supporting programs played a central role in developing an environmental education model for formal schools and enhance the importance of environmental education in school curriculum. This study aims to evaluate the current statues of environment conservation model schools and support to environment conservation model school initiatives which have created basic framework to enable the continued development of environmental education. For the study, documents and reports from 1985 to 2005 were analyzed, which included operation guidelines for model schools, case studies, implementation reports along with the systematic analysis of documentations. Also this study included interviews and a survey with people responsible for running programs, and consultation processes with experts to address the current status and issues related to Environment Conservation Model School initiative. Based on the present status and issues, the recommendations for improving Environment Conservation Model School initiative were provided.

This paper represents a critical review of current the relationship between aquaculture and the environment, focusing on the development of marine aquaculture for conservation of resources and environment in Korea. Aquaculture has grown rapidly during the past few decades in Korea. This expansion was possibly because of the growing demand for aquatic products and the failure of the capture fishery to keep pace with the demand. Nevertheless, the aquaculture industry must counter criticisms about adverse environmental effects and lack of sustainability. The productivity of Korean aquaculture is decreasing by environmental pollution, is suffering difficulty because competitive power of the aquaculture industry is weak, external effects of aquiculture is giving negative effects to coastal fishery. Therefore, aquaculture must improve as environmentally sound aquaculture for fisheries sustainability, and intensive aquaculture of high density must convert by low input sustainable aquaculture. Finally, the aquaculture system of Korea has to change to aquaculture for conservation of non - renewable resources and environment, it may contribute to development of Korean fisheries.

Present status of Japanese wetland ecosystems and several trials towards rehabilitation and restoration of them are reviewed. Most of wetlands are altered to paddy fields and city areas, and natural wet lowland including tideland is the most endangered nature in Japan. Not only the preservation of natural wetlands but also the conservation of secondary nature of paddy field and waterways in traditional rural areas and restoration of original nature in city areas became the most concerned theme for nature conservation according to the national strategy for the biodiversity conservation. Not only the technological development based on the conservation ecology, but also the development of mitigation banking system are needed in Japan.

Kinetic energy conservation for fixed and moving grids is examined in time-accurate finite element computation of fully unsteady inviscid flows. As numerical algorithms, fractional step method (FSM) and modified SIMPLE are used. To simulate the flow in moving grid system, arbitrary Lagrangian-Eulerian (ALE) method is adopted. In the present study, the energy conserving time integration rule for finite element algorithm is proposed and discussed schematically. It is shown that the discretization by Crank-Nicolson in time and Galerkin (central difference) in space must be used to ensure energy conservation. The developed code has been tested for a standing vortex in fixed or moving grid system, sloshing in a tank and propagation of a solitary wave, and has been shown to be a completely energy conserving algorithm.

The study aims to draw out implications regarding systematic reservoir management through analyzing the reservoir conservation activities and policies in Hyogo Prefecture which has the most agricultural reservoirs in Japan and similar agricultural form to that of Korea. The results are as follows. First, it turns out that consistency in policies and persistent drive are key to success. Since the late 1990s, the Hyogo Prefectural government has expanded the reservoir conservation policies, consistently trying to ellicit the multifunctionality of reservoir, and also has shown persistent drive toward the conservation policies through systematic process. Second, it is clear that the Prefectural government has shown a great degree of activeness. It established ordinances before acts were legislated by the central government. In addition, the Hyogo Prefectural government ran a supportive organization with its own funds. Third, the establishment of systematic enforcement system played a critical role. The efficiency in the policy enforcement derived from the dual conferences, Prefectural-level conference dealing with the related policies throughout the Prefecture, and local-level conference discussing policies based on regional characteristics.

As the water shortage has become a noticeable issue due to climate change, forests play an importance role as the provider of water supply service. There is, however, little information about the relationships between the factors used in the estimation of water supply service and coarse pore fraction of forest soil which determines the potential of water supply. To find out whether there would be an amelioration in the scoring system of water supply service estimation, we examined all factors except meteorological one and additionally, analyzed 4 extra factors that might be related with coarse pore fraction of soil. A total of 2,214 soil samples were collected throughout South Korea to measure coarse pore fractions from 2015 to 2020. First, the result of average coarse pore fraction of all samples showed 32.98±6.59% which was consistent with previous studies. And the results of non-parametric analysis of variance indicated that only two of eleven factors that was used in the scoring system matched the results of coarse pore fraction of forest soils. Tree canopy coverage showed no difference among categories, and slope also showed no significance at level of 0.05 in the linear regression analysis. Additionally, the applicability of 4 extra factors were confirmed, as the result of coarse pore fractions of soil samples were different for various categories of each factor. Therefore, the scoring system of water supply service of forest should be revised to improve accuracy.
