This study was conducted to develop environmental restoration methods for the ecological restoration of the rock exposed steep cut-slopes using native woody plants seeds by the hydro-seeding with artificial soil media. The main results are summarized as follows; 1. Quercus spp. seeded after seed treatment germinated over 80% and most of them grew well until one year. So, Quercus spp. can grow at the extremely dry rock exposed slopes revegetated by hydro-seeding with soil-fertilizer-seed mixed media. 2. The germinated seedlings grew well at the slopes oriented southeast. But in case of the survival ratio of the germinated seedlings, northwestward slopes was the best. 3. In case of the using pot seedlings of the Miscanthus sinensis var. purpurascens, it shows more beautiful scenery than the area using cool-season grasses. 4. As the results of the experiment, Albizzia julibrissin, Quercus spp. and Lespedeza crytobotrya can be useful at the restoration and revegatation of the cut-slopes. 5. At the results of the seed mixture experiment, cool-season grasses covered the ground quickly, but slowly germinated Quercus spp. and Lespedeza crytobotrya formed under story vegetation. Also, Albizzia julibrissin formed upper story vegetation will be replaced by Quercus spp. slowly.

This study was intended to develop and suggest 'residents-driven and citizen-participatory restoration procedures' for degraded ecosystems in BaigDooDaeGahn. With some concerns of current engineering-focused restoration approach for damaged ecosystem, the proposed procedures were designed based on the analysis of several case studies on citizen participatory projects such as the Habitat Movement, the Taean tidal wetland restoration effort in Korea, and some historical and innovative cases in Japan and the United States. The suggested procedures were considered to be a dialectical spiral model which was consisted of two goal axis, six system elements, four developmental stages, and five restoration steps. The new system and procedures were applied to damaged farmland areas (about 0.3 ha) on the top of BaigDooDaeGahn, Kangneung city with participation of more than 100 local residents and a dozen of citizen from Seoul. Both high level of possibilities and some barriers for future extended application were identified and adopted for the final version of the proposed procedures for ecological restoration.

Ecological restoration aims to reverse the degradation of ecosystems that occurred as humans have affected landscapes. This study was conducted in part of a larger project to develop participatory ecological restoration procedures for disturbed areas in Baigdoodaegahn which is a major mountain range in the Korean Peninsula. The case of alpine farmland at Kangwon-do was selected to apply the theoretical framework of participatory restoration since the nutrient contents in alpine solid under vegetable cultivation degrade water quality in the watershed while farmers in the region are economically struggling due to imports of vegetables from China. The reciprocal model of restoration was applied to cope with interactions between human and ecosystem needs in ecological restoration. A series of environmental education and eco-tourism programs were developed and incorporated into the participatory restoration project to rebuild social-cultural aspects of the community as well as to restore the biophysically disturbed area while meeting both ecological needs and human needs. This study suggests that participatory projects will be more successful when experts support the local residents and citizens in restoration process, when leadership are developed through social learning, and when ecological, financial and social factors of restoration are integratedly considered.

Stereoscopic viewing is an efficient technique for not only computer vision but also remote sensing applications. Generally, stereo pair obtained at the same time is necessary for 3D viewing, but it is possible to synthesize a stereomate suitable for stereo view with a single image and disparity-map. There have been researches concerning the generation of the synthetic stereomate from remote sensing imagery. However it is hard to find researches concerning the restoration of occlusion in stereomate. In this paper, we generated synthetic stereomates from remote sensing images, focused on the occlusion restoration. In order to figure out proper restoration methods depending on the spatial resolution of remote sensing imagery, we tested several methods including general interpolation and inpainting technique, then evaluated the results.

This study focuses on the technology to reduce destruction and damages of an ecosystem in the process of road construction. The authors investigated the ecological conservation activities and restoration technology which were applied to the construction of 2 bridges in Japan. The key results are as following : First, the most important thing in constructing eco-road was the linear design. Second, we need to adopt the environmental construction forms and materials to the design of structure. Finally, we have to use environment-friendly methods for the sake of the ecosystem at the real construction stage. Adopting those technologies has at least a few merits. First, we can achieve out goals : conservation and restoration in the local habitat. Second, we can save money instead of building a eco-bridge. There is a further advantage which makes it possible to develop environment-friendly technologies than before by drawing developers' attention.

In recent Japan, the demand for woodland creation on revegetation sites is increasing. In the forests and woodlands, we can find many functions of environmental conservation, in addition of biomaterial production, and all of these existences with such functions are defined as environmental woodlands. Many woodlands has been created from old times for the purpose of forest conservation and flood control, and most of these technology are handed down to present time. After Edo era (from the beginning of Meiji era, 1867), some valuable examples of woodlands were created, like Meiji shrine woodland in Tokyo. After the World War II, a lot of technology for woodland revegetation, such as ecological tree planting, have been developed. At present, many revegetation sites are aiming at woodland creation, like on man-made slope, etc.. In the great change of social structure, revegetation technology is also required to keep in close relationships to the restoration of devastated existing forests and woodlands, and to provide many technology for the restoration of secondary woodland, preservation of soil, mitigation, reclamation, etc.. Now in Japan, the improvement of environment including all the member of biosphere is demanded on a large scale. Therefore, revegetation technology should also try to make an activity taking a broad view of the restoration of natural vegetation in addition to the traditional and new woodland creation.

Expressways are often upgraded by widening the lanes and/or by reshaping the roads to be more linear for faster travel time. However, during the process of improving the route of the expressways, the areas where the old expressways used to be are often unused and abandoned. When these neglected sites are left alone, they often become dump sites causing pollution and impacting the surrounding environment. Therefore, it is important to restore the abandoned expressway sites to its full natural beauty. In this study, the abandoned expressway at the Soksa interchange in Pyungchang county, located in Kangwon province was studied for establishing the model of ecological restoration project. Considering the characteristics of the site, the target flora species was chosen to be Quercus species and the target fauna species as amphibians. After the target species were carefully chosen, each species' habitat requirements were studied in order to figure out the appropriate methods toward habitat restoration specifically for these species. In addition, to determine the most efficient method toward restoration of abandoned expressways, the study utilized the planting hole techniques, the crack techniques, and the colonization techniques. In terms of the spatial organization, public education program is incorporated at the main entrance area and the programs for experimenting, and developing vegetation and habitat restoration techniques are placed in the vicinity. In the master plan-to provide natural ecosystem at the site-ASCON (asphalt concrete) was removed first, then plans for restoration including species' habitat restoration were established. Furthermore, the project included plans for improving water quality polluted through non-point source considering the surrounding nearby road and farm lands. Finally, the study established a planning process that will experimentally apply to the abandoned expressway restoration method. In the future, there will be a continuous monitoring of the methods applied to verify if the restoration methods are effective. Also, new restoration techniques should be available according to a variety of abandoned expressways' characteristics.

According to the new general movement of ESSD in Korea, the role, background, and subjects, etc. of Ecological Restoration Area were studied to find out the way for this area to be settled as one kind of industry. Questionnaire and literature study were carried out to understand and to find out the way of the area settlement with the conceptual and practical definition of it. The related sub-areas studied were 1. regulations and standards including design and construction 2. researches and developments around the area 3. related curriculums applying in the educational organizations 4. present situation of the industry. Followings are the results of this study and several proposals for the area to be settled in Korea with the other related areas. 1. The boundary of Ecological Restoration could be defined as the concept of preservation(or conservation) and restoration of the ecosystem with ecological planting - including the restoration strategies for the areas of slope, artificial foundations, watersides and wetlands, with in bio-diversity and eco-forests for these areas. 2. It seems that the more investments needed for the elaborate and professional techniques to be developed for the design and construction works to the contrary that the base of this area be matured already in the several sub-areas. 3. For the successful work of Environmental Restoration, defining the new industrial branch -independent from existing construction industry- is recommended through the law system under the control of the Ministry of Environment. It will be better if professional officer system in governmental organization could follow up this. 4. Educational organization and Technical expert qualifying system to train the Ecological Restoration Professionals should be induced for the effective practice of the area.

Sparganium japonicum Rothert. is designated as a near threatened species by the National Institute of Biological Resources and is restrictively distributed in South Korea. To conserve and restore habitats of this plant, we investigated environmental characteristics and vegetation at five habitats during the growing season. Thirty plant species from seventeen families were found in the S. japonicum community. The species frequently found in this community included Utricularia vulgaris, Potamogeton distinctus, Phragmites japonica, Cicuta virosa, Persicaria thunbergii, Phragmites communis, Hydrilla verticillata. Maximum height of this plant reached at August and average height at five habitats is 120 cm at this time. Water and soil environmental factors showed low values compared with that of other wetlands. S. japonicum lived in not only shallow water level but also deep water level. These results can be helpful for S. japonicum habitat conservation and restoration.
