This study is intend to evaluate natural conservation value, and to suggest natural park plan based on conservation value evaluation. In this study evaluation items are selected through related studies about ecological conservation evaluation, and evaluation items in this study can be classified into 2 aspects, ecological environment and topographic environment. After each evaluation items are overlaid with GIS program, management levels are derived from comprehensive overlaid maps of each evaluation items. Management areas can be classified into 5 levels; Critical Conservation Area, Conservation Area, Restoration Area, Passive Usable Area, Active Development Area and Settlement Area. So management areas can be matched each management levels to land use of natural park, that is district of preservation, district of natural environment, district of settlements and district of mass facilities. This study have good enough to evaluate ecological value for natural park plan, but, it is difficult to evaluate conservation value only with maps of each evaluation items, so it needs supplementary field survey for precise conservation value evaluation.

Environmental pollution has become more and more serious in urban areas since industrialization as most streams and rivers were developed heavily because of economic opportunism. Recently river restoration techniques, applied in advanced countries, have been introduced to Korea. But the application of river restoration techniques developed in advanced countries, has a lot of limitations in respect of economic loss during construction, suitability for the domestic situation and the problem of flood control. The method of minimizing the problems must take into consideration these issues, including economic considerations. So from these points of view this study intends to plan ecological river restoration and to create a nature friendly river in the case of the Chungrang river. The subject site is the upper part of Chungrang river, from the Nokchun bridge to Sang-kye bridge, where the ecosystem is well preserved in comparison with other parts of the river. The subject site is divided into 10 sections for plant state investigation. The result of plant-state investigation showed pioneer water plants such as Persicaria thunbergii, Oenanthe jaranica, Rumex crispus. appeared very often. On the basis of the existing plant state, this study has planned an appropriate plant state for the river and has planned for bank protection using a method of construction, which is suitable for natural river. In this study, first of all, it is intended to investigate the plant growth state of Chungrang river and try to plan a particular ecosystem for the river for the purpose of the revival of the natural river.

The factors of local disappearance and a plan of restoration fer Parnassius bremeri from Okchon-gun, Chungchongbukdo, Korea, were investigated. The population of this butterfly from Okchon-gun was much more abundant than the other areas of Korea in the past. But only two adults were observed in 1997 at this site and no more observation was made in 1998. So we considered that Parnassius bremeri is disappeared from this area. To know the factors of local disappearance of this species, we analyzed data of the monitoring from seven localities of Okchon-gun from 1990 to 1998 and also checked 252 specimens from this area by several collections. As a result of it, the habitat changes by recent road constructions and the frequent collecting activity around this area are shown as the factors for the local disappearance of this species. We are intending to establish the programs for restoration of Parnassius bremeri in Okchon-gun. Firstly, the breeding plan of this species was designed by investigation on life cycle. Secondly, the environmental conditions among seven localities were compared and the suitable places of the restoration were selected. The most suitable localities for restoration by this study were of two localities, Dongrakjeong and Jangwahri, which are considerd as highly successful breeding places in the view of growth condition of host plant.

This study carried out for establishing the synthetic restoration plan to improve ecological quality of Mt. Mudeung National Park based on the results of conservation value assessment for yellow-throated marten habitats. Yellow-throated marten has significant implications as umbrella species for the wildlife habitats conservation, therefore, this species could be used to ecological restoration plan of the damaged forest ecosystem in Mt. Mudeung National Park. In this study, we diagnosed the quality of yellow-throated marten habitats in Mt. Mudeung National Park based on five natural and two artificial factors. In addition, we evaluated the integrity of each zone divided by trails quantitatively based on land use intensity. As a result, forest landscape quality in Mt. Mudeung National Park was influenced greatly by human activity and the degree was depended on the intensity of trails. Therefore, in this study, we suggested the closing of trails composed of the illegal and 36 legal trails. And then, we modeled the changes of habitats quality of Yellow-throated marten for each closing step. As a result the area of core habitats increased by two times and wildlife habitats quality improved in the whole area of the Mt. Mudeung National Park. As a result, the results of this study indicate that man-made linear landscape elements play a key role in the quality of habitats for predators, which require large habitats area like the Yellow-throated marten. Therefore, in order to establish an ecological restoration plan in the mountainous area, we recommend the concept of the linear landscape should be applied with the concept of area landscape.

This paper, describe about a generation of a syllable restoration regulation for a post processing of a speech recognition and a decrease of a restoration candidate. It created a syllable restoration regulation to create a restoration candidate pronounced with phonetic value recognized through a post processing of the formula system that was a tone to recognize syllable unit phonetic value for a performance enhancement of a dialogue serial speech recognition. Also, I presented a plan to remove a regulation to create unused notation from a real life in a restoration regulation with a plan to reduce number candidate of a restoration meeting. A design implemented a restoration candidate set generator in order a syllable restoration regulation display that it created a proper restoration candidate set. The proper notation meeting that as a result of having proved about a standard pronunciation example and a word extracted from a pronunciation dictionary at random, the notation that an utterance was former was included in proved with what a generation became.

This study was started with the objective of restoring abandoned embanked farms, which are recently increasing, to mud flat by putting in least amount of energy in the aspect of environmental restoration. For the direction and establishment of the proposal for the restoration of mud flat using embanked farms, a case of Maipo Wetland in Hongkong was analyzed, and a proposal was prepared considering the condition of mud flat in Gochang. The restoration of mud flat in Gochang is intended to create various wetland ecological spaces as well as to provide opportunities for experience, education, recreation, and tourism. Effort was made to development an environment closest to the local ecological environment considering the shape and topographical condition of existing abandoned farms. For construction of the habitat, a target species was chosen and the plan for selection, planting, and management of species of trees suitable for the target species was established. In addition, the water level will be controlled by water gates to conform to the resting, spawning, breeding, and migration period considering the behavioral pattern of waders, the target species. The research on the restoration of mud flat in Korea is in incipient stage and this study provided an opportunity to review the possibility of restoration of abandoned embanked farms to mud flat. For the success of mud flat restoration from a long-term perspective, development of acclimating design infrastructure, technology improvement for mud flat restoration, and basis of partnership for the maintenance should be prepared in a systematical way.

This paper presents for service restoration Abstract -in electric power distribution systems. The aim of the service restoration is an emergency control in distribution system to restore out-of service areas as soon as possible when a fault occurs in distribution system. For this reason, this paper presents a new service restoration strategy for multi-outage areas. Proposed algorithm consists of two methods. One is individual restoration scheme, the other one is integrated restoration scheme. The former determines restoration order of outage areas based on restoration index. If the former method can not generate a feasible restoration plan, the latter would try to find new configuration without overloaded section through tie exchange method.

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.
