The purpose of this study is to explore the necessity and possibility of establishing a research institute for local educational autonomy where the importance and necessity of institution establishment and operation are increasing with the decentralization and educational autonomy. The necessity of establishing a local educational autonomous research institute was examined in terms of both external and internal necessities, and the possibility of establishment in terms of the form of establishment, financial resources, and legal basis. In order to effectively cope with common issues by leading the nation's educational autonomy policy and legal agenda, and to support regional policy research and development by linking and cooperating with regional educational policy research institutes, local educational autonomous research institutes are established. This is an urgent point. Considering the publicity, professionalism, economic feasibility, and stability of specialized research institutes, the form of foundation corporation seems to be appropriate, and, like the case of specialized research institutes in general local autonomy, legal grounds for the establishment of special law should be prepared. In the future, it is necessary to conduct collaborative discussions and academic discussions with the Ministry of Education and the National Council for Superintendents of Education.

A geographical information systems(GIS) was a useful aid in the assessment of urban nonpoint source pollution and the development of a pollution control strategy. The GIS was used for data integration and display, and to provide data for a nonpoint source model. An empirical nonpoint source loading model driven by land use was used to estimate pollutant loadings of priority pollutant. Pollutant loadings were estimated at fine spatial resolution and aggregated to storm sewer drainage basins(sewershedsl. Eleven sewersheds were generated from digital versions of sewer maps. The pollutant loadings of individual land use polygons, derived as the unit of analysis from street blocks, were aggregated to get total pollutant loading within each sewershed. Based on the model output, a critical sewershed was located. Pollutant loadings at major sewer junctions within the critical sewershed were estimated to develop a mi t igat ion strategy. Two approaches based on the installat ion of wet ponds were investigated -- a regional approach using one large wet pond at the major sewer outfall and a multi-site approach using a number of smaller sites for each major sewer junction. Cost analysis showed that the regional approach would be more cost effective, though it would provide less pollution control.

Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

A large-scale sensor network usually operates in open and unattended environments, hence individual sensor node is vulnerable to various attacks. Therefore, malicious attackers can physically capture sensor nodes and inject false reports into the network easily through compromised nodes. These false reports are forwarded to the base station. The false report injection attack causes not only false alarms, but also the depletion of the restricted energy resources in a battery powered network. The statistical en-route filtering (SEF) mechanism was proposed to detect and drop false reports en route. In SEF, the choice of routing paths largely affect the energy consumption rate and the detecting power of the false report. To sustain the secure routing path, when and how to execute the path re-selection is greatly need by reason of the frequent network topology change and the nodes's limitations. In this paper, the regional path re-selection period determination method is proposed for efficient usage of the limited energy resource. A fuzzy logic system is exploited in order to dynamically determine the path re-selection period and compose the routing path. The simulation results show that up to 50% of the energy is saved by applying the proposed method.

This study is to discuss the problems due to the maldevelopment occurred at the reserved areas of natural environments of the Ulleung Island, Gyeongsangbuk-do province, and it also suggests the ways of solving them The types of the maldevelopment practiced on the Ulleung Island consist of the change of land use, the opening of a round road, the destruction of mountains for the construction of harbor, the development of tourist areas, and the construction of military facilities. The decreased habitat of animals and the pollution of drinking water are occurred by the change of land use. The destruction of ecological system is due to the opening of a round road. The damage of natural landscape and the change of ocean eco-system is closely related to the construction of harbor and the destruction of mountains. Finally, the damage of rare plants and the pollution of drinking water are due to the development of tourist areas and the construction of military facilities. In the followings, the ways of solving the problems occurred by the various types of maldevelopment are suggested. First, the planning of pro-environmental development has to be established and practiced to preserve rare plants which are damaged due to the change of land use. Second, the destruction of natural landscape and resources has to be minimized by the implementation of environmental impact assesment when road and harbor are constructed. Third, the stones needed for the development of islands ought to be imported from mainland. Fourth, the established tourist areas are needed to rationally manage and the potential tourist areas has to be transferred to the reserved areas of natural environments. Fifth, military facilities should be constructed though the cooperation of autonomous local government. Finally, government officers' and residents' conscience of protecting and reserving natural environments is needed, and government has to give residents financial supports.

In this study, the satellite images and the GIS technique are used to select the basin characteristics parameters as the basis of water resources management of river basin. The study area is Geum-ho river basin and the hydrologic characteristics data are computed through the database of the basin characteristics parameters classified by subjects with 35 maps correspond to the study basin of 1:25,000 scale as the basic map. As the result, the drawing up of land use map through satellite image processing that provides the quantitative informations for the land is very efficient to analysis the extensive land use information of the basin, and exact analysis of mass surface data is possible and the feasibility of statistic computation between spatial subjects as it superpose on other subject map is ascertained. It is thought also that the analysis of the basin characteristics data can be utilized very effectively for the basin management and the analysis of basin surface area, once it is expressed numerically for database, since the superposition analysis with different subject map and the correlative analysis with the property data are possible although the tracing process of each subject in the basic map is not efficient. Especially, modification and renewal of the data for the change of land surface become easy, therefore more rapid and exact selection of the basin characteristics data and the construction of more efficient basin management plan are possible.

This paper is to analyse a changing space of energy flows in Northeast Asia from geopolitical and geoeconomic perspectives that have been recently promoted for energy security of countries in this region. The research is based on an analytical framework in an integration of political ecology and political economy. Because of an ever-increasing input of energy resources for economic growth and of dramatically increasing price of crude oil and recent instability of oil market, South Korea, China and Japan have been deeply concerned with energy security and conducted very actively geopolitical strategies. And hence the space of energy flows in the region is now in a process of dynamic reconfiguration, in which the project for development of oil and natural gas fields in East Siberia and construction of pipelines to transport them can be seen as one of competitive issues among these countries. In spite of worrying about stagflation due to rapid increase of oil price, such geo-strategies for energy security and reconfiguration of space of energy flows seem to keep the accumulation of capital in this region continue with generation of huge privatized oil companies.

Having gone through the international financial crisis in 1997, the Korean government has sought a new future economic breakthrough. In this line, the government chose the cultural contents business and has supported this area intensively. With the cultural contents promotion policy initiated to foster the world-class culture business based on the traditional Korean culture, Andong, which has diverse cultural traditions, was rediscovered. The Andong local government and the local power elites decided that this promotion policy can not only be an opportunity to invigorate the sluggish local economy, but also help eliminate the old-fashioned image of Andong, and thus actively promoted the cultural contents business. However, there's a conflict among the local elites over which cultural tradition should be chosen as a genuine local cultural tradition. The different views and efforts regarding the cultural identity of the region by each entity not only contributed significantly to the recovery of the local economy by revitalizing tourism, but also helped the region gain an advantageous position in competition with other regions over limited resources. This progress became the groundwork for attracting major institutions and facilities, which are essential for the revitalization of the local economy.

The commerce and industry of Busan was developed because of good geographical conditions with harbor. After passing its settling-down and diffusing time, Busan has grown in the trade city. Busan has lost the competitive power of the port city since 2000, because of the weakness of its economic power which is caused by the secession of manufacturing industry and the decrease of resident population and foreign tourist. In order to overcome these weaknesses, it is necessary for Busan to take the innovative strategy for the activation of marine tourism. This goal can be achieved by the strong quality of the port city, the coastal terrain, the traditional industry and the international traffic. The aim of this paper is to explore the Innovative Strategy for the activation of marine tourism in Busan and to suggest the following proposal. First, the government must decide the base of marine tourism under the geography viewpoint of the coast and sea, and develope tourism resources after analyzing the identity of marine tourism base. Second, the core part along the selected bases of marine tourism must be constructed the tourism terminal as the landmark of Busan in order to concentrate foreign tourist. Third, after each base of marine tourism must become the resort for tourists, they are able to experience the activity of marine tourism in this resort. Therefore, each base must be specialized. Fourth, each base must be connected with the route of marine tourism Fifth, in order to overcome the off-season of marine tourism, winter tourism goods such as skates, skis, artificial sea-bathing pool, artificial swimming beach, artificial sled, artificial rock wall of coast, hot spring resort of salt water are required to be developed in the center of marine tourism base.
