Confidentiality is one of the most important requirements of information protection systems. The access control technique has been used to provide confidentiality, but it has fundamental problems in that it cannot prevent violations of confidentiality committed by authorized users. Information flow control is a technique introduced to resolve such problems, and many approaches based on programming languages have been proposed. However, it is not easy for a programmer to implement the technique at the source code level. Furthermore, the practicality of information flow control is difficult to demonstrate because it does not provide control over programs that have already been developed. This paper proposes a method that enables a practical information flow control through using a protected area, a separate part of computer system storage. Case studies are given to show its usefulness.

This study has been carried out with the purpose of coming up with suggestions for designation of domestic protection areas and improvement of their management through a comparative analysis of the systems of management of the protection areas in South Korea, Japan and China. Starting with the designation of natural reserves in 1962, South Korea has prepared legal systems for preserving ecosystems and biodiversity, while continuing to designate protected areas. As the state has so far monopolized the designation and management of all South Korean protection areas that take up 10.8% of its entire land area (as of Dec. 2011), with such persisting issues as multiple designations of one and the same area for protection, overlapping management authorities, and management of privately owned land in the protection areas. In Japan, which has protected area sizes and relevant legal systems similar to those in South Korea, the state provides the basic framework for management, while delegating most of the duties related to direct operation and management to specific municipalities. China, with an integrated administrative management of protected areas, has related government offices and municipalities responsible for the designation and management of individual protected areas. South Korea needs to provide a legally based support system that would further enhance the value of areal protection and contribute to the promotion of local economy and community.

The Wetland Conservation Plan is used as a tool to set the management direction of wetland protected areas, and which is establishing a plan for the conservation, wise-use, and management based on wetland's condition. This study was conducted to establish a conservation plan considering the functions and management conditions of Upo wetland protected area. To this end, there are analyzed the current issues, plans and implementation status of Upo Wetland Conservation Plans in the past. The management elements to be considered in establishing the Wetland Conservation Plan were selected through prior research analysis and the priority of those elements was identified through the AHP. As a result, it was found that lack of considering the changes and performance evaluation of the existing plans in wetlands, conducting short-term projects related to maintenance original function of wetland, different management methods for wetland protected areas and other adjacent areas, lack of understanding and cooperation by stakeholders, inconsistencies in timing of the Conservation Plan and survey of wetland protected areas. In order to improve the problem, it needs to include the performance evaluation stage of establishing the conservation plan, strengthen cooperation of stakeholders and expertise, continuing of projects for wetlands' maintenance, priority of the project considering the management side, and to adjust the timing of plans to improve data availability.

It is neceesary to evaluate the location suitability of protected cultivation facilities to guide reasonable protected cultivation. The evaluation system could help plan new protected cultivation facilities in rural areas. In this study, an assessment was made for the facilities located in three different selected regions: suburban, plain, and mountainous. The assessment was performed based on spatial characteristics of protected cultivation facilities such as land category, size of protected cultivation facilities, land shape, stoniness, land consolidation level, soil drainage, land slope, topography, effective soil depth, zoning or not of agricultural development area, irrigation and drainage condition, distance from roads, and so forth. The results showed that there were significant differences in locational characteristics among the three regions.

A protected area means a space designated and protected by law from development pressure and environmental pressure. It is mainly designated to protect specific ecosystems, natural landscapes, and cultural resources from irrational development (or damage), and involves policies of the public sector such as central and local governments. The United Nations Educational, Scientific and Cultural Organization (UNESCO) has conducted conservation and restoration projects for preserving natural ecosystems and genetic resources. In order to conserve the ecosystem in the protected area, national and public organizations purchase private land and use it ecologically; in addition, ecological restoration project is carried out for the purpose of creating waterside ecological belt or preserving ecosystem. Land acquisition refers to the land where highly influenced by the water quality and need to restore, and purchased by negotiating with the landlord. Although the nation and public institution carried out ecosystem restoration project for partial purchase land in order to conserve ecosystem, it is below the expected effect due to lack of comprehensive management system and have some problems in restoration project and unification of management institutions. Land acquisition in Donggang River Basin Ecological Conservation area is initiated in 2005 for creating income of local residents and ecological restoration. However, the lack of overall management and awareness resulted in poor vegetation growth and poor response by local residents due to terrain exposure. As such, there is insufficient research on the current situation and systematic integrated management although the number of land acquisition is increasing year after year. Futhermore, overall recognition and follow-up monitoring of eco-restoration are still inadequate. Therefore, the survey on the awareness of the purchase land ecosystem restoration project is necessary for the efficient restoration project and establishment of the management strategy for land acquisition in the future. Therefore, in this study, we provide fundamental materials on further research projects by carrying out research on the awareness of ecological restoration projects in the Donggang River basin ecological preservation area.

This study was aimed to design core areas applied by the global conservation criteria to promote the public awareness to the protected areas and the value cognition of the Key Biodiversity Areas (KBAs), targeting the Mt Seorak, according to the designation of globally important biodiversity areas. As a method for carrying out this study, the biota were cataloged through literature reviews and field trips. With applied by the Global Red List criteria of the International Union for Conservation of Nature (IUCN), only nine species were categorized in the studied area; plants were classified into six species as follows: Megaleranthis saniculifolia ohwi, Bupleurum euphorbioides Nakai, Hanabusaya asiatica Nakai, Thuja koraiensis Nakai, Leontopodium leiolepis Nakai, Androsace cortusaefolia Nakai, fish was classified one species as follow: Pungitius sinensis Tanaka, and the mammal was classified as two species as follows: Hydropotes inermis, Naemorhedus caudatus. According to the occupation area (EoO, Extent of Occurrence) and Minimum Viable Population(MVP), the size of protected area was 234.56㎢ for plants, 235.07㎢ for mammals, and 0.14㎢ for fish, and the Key Biodiversity Area (KBA) of Mt. Seolak suggested as 286.72㎢.

The Korean government has put mamy efforts into the protection of ecological values of coastal and marine ecosystems since the mid 1990s, recognizing ecological values and economic contributions of coastal and marine ecosystems. Rapid increase of coastal and marine protected areas in terms of number and size implies the innovative change of national policy regarding ecosystem protection. As of the end of 2006, the total number and size of the protected areas account for 425 and $10,666.8km^2$ respectively. Despite of this achievement, the current policy regime on the protected areas has not been quite successful dealing with in managerial issues. The ambiguity and the lacking objectivity of designation criteria have, been causes of pending issues such as conflict outbreaks, 'paper parks', duplicated designation, etc. This paper aims at improving current designation criteria based on AHP(Analytic Hierarchy Process). The suggestion of the study covers both the new designation criteria and the weighing factor on each criterion considering different ecological and socio-economic characteristics of 'wetland protected area' and 'marine protected area'.

Ever-growing recreation, tourism and ecotourism worldwide have become a significant factor of resource degradation in many protected areas. Managers of these areas are increasingly challenged to implement policies, strategies and actions that would protect the resource base while providing quality visitor experience. One major issue in managing protected area visitations is that of carrying capacity, or the question of "how much use is too much\ulcorner". Scientific studies of visitor impacts, often known as recreation ecology, has generated a knowledge base that provides valuable input to the visitor carrying capacity management process adopted by the U.S. National Park Service. This paper aims at (a) providing an overview of recreation ecology research and its application in managing visitor carrying capacity, and (b) examining the relevance of recreation ecology to East Asian protected areas with special reference to the visitor capacity issue.ity issue.
