Most of all Castle Remains in Korea were built on an axis of development with a scale of great magnitude. Because of its characteristics, the restoration and conservation plans should be phased in over medium and long term. There is no standards for evaluating the value of Castle Remains to set up the restoration and conservation sections. Some plans were set up through the value evaluation of its Castle Remains but those plans didn't have Evaluation System and different weight depending on different environment between Sanseong(mountain fortress) and Eupsung(fortress built in villages). To solve the limitation of Evaluation System of Castle Remains, this study try to approach in the Evaluation System methodology for selecting restoration sections. The results of its study follow below. First, this study drew the Evaluation Indices for selecting restoration sections of Castle Remains. There are three kinds of Elements(upper Index) and nine kinds of Evaluations(low Index). Second, Calculation of weight index by index on the questionnaire survey from expers through the relative importance analysis of AHP. Third, This study suggests the specific Evaluation System according to types; Sanseong(mountain fortress) and Eupsung(fortress built in villages);. Therefore, this study suggests standards to select the priority list for the restoration and conservation plan process and it can be used one of important standards in future plans.

Studies on ancient iron production technologies still have challenges to overcome, although there have been many results that have enabled us to understand these old technologies. The purpose of this study is to propose a suitable temperature condition for smelting experiments. The target for reconstruction is a smelting-smithing process in the ancient Jungwon area, and the experiment was designed on the basis of published research, such as archaeological evidence. Experiment A was performed at a low temperature to produce low-carbon iron, while Experiment B was conducted at a relatively high temperature to synthesize high-carbon iron. In addition, the low-carbon iron proved to be suitable for the smithing process. Moreover, aspects such as the microstructure and chemical composition of the slag and the surface condition of the furnace wall showed that the low-temperature smelting process was closer to the ancient method. It is important to mention the premise that the reconstruction of ancient technology can be achieved when the results of an experiment replicate the conditions of a real site. The results show that direct smelting, which produces low-carbon iron bloom under a low-temperature condition, should be the subject of smelting experiments concerning the iron production technologies of the ancient Jungwon area.

This paper describes the restoration and display of a large jar coffin at the Naju National Museum. Excavated from Tomb No. 3 at Bokam-ri, Naju, the large jar is 194 cm in height and its rim diameter is 108 cm. The jar had been broken into approximately forty fragments prior to its restoration, and a supporting structure was installed to ensure the safety of the relic during the restoration process. The restoration was conducted inside a visible storage for large jar coffins for approximately three weeks from February 5 to February 27, 2018. Over two weeks during this period, the restoration efforts inside the storage were visible to the public in the permanent exhibition space so that visitors could observe the process in person. This was planned to help visitors understand and arouse their interest in large-sized relics such as jar coffins and the restoration process. This study also investigates the practices of overseas institutions in order to suggest plans for raising public awareness of conservation treatment at conservation science centers.

The sinkhole and leakage in dam core were detected at one of earth fill dams in Korea. The damage areas in the core of the dam were repaired by compaction grouting method. This study is to evaluate compaction grouting activity by in-situ and laboratory experiments before, during and after the remedial work. The intensive site investigation and geophysical survey were conducted during and after the compaction grouting work. The compaction grouting work was carried out for the damaged dam core between June 16 and August 24, 2000. The leakage reduction generally occurred in the core of the dam after the remedial work. The use of compaction grouting was considered the proper countermeasures for repairing the damaged dam. It shows that the loose or voided zones have been properly filled and the leakage has been reduced by about 96% of that before the treatment of the remedial work performed at dam core by compaction grouting.

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.

Most domestic small rivers and streams due to industrialization and urbanization have managed by concrete structures. The environmental functions of the river and stream are disappearing and urban streams play only the role of drainage systems. Also, the researches to restore natural streams are something yet to develop and not established the restoration for ecological functions of a small stream. Therefore the researches are required to develop ecological engineering system for watershed management system to handle various pollutants with restoration for ecological functions of a small stream. To develop this, the ecological engineering system for watershed management system could be developed with ecological conservation. In addition, ecological engineering system for watershed management system should be prior to conserve the habitat of biological resources and water conservation and applied to the original shape of streams. Also, it should be designed to restore the micro-topography of stream, the habitat of plant population in watershed. It is needed to develop the integrated researches to restore a small stream ecosystem.

도시하천은 Eco-network의 근간이며, 하천을 통해 인간이 느낄 수 있는 정서적인 안정감, 친밀감, 쾌적함 등 어메니티의 모체로서, 최근 도심내 Open space로서의 위상을 높여가고 있다. 양재천을 위시하여 수원천, 전주천 등 지역을 대표하는 하천들이 자연형 하천으로 정비되어 하천 이용에의 관심이 고조되고, 청계천의 성공을 기점으로 하천의 친수공간으로서의 기능이 강조됨에 따라 도시하천에 대한 개발 요구도는 급속히 높아지게 되었다. 이러한 개발요구의 급속한 증가가 있음에도 불구하고 보전과 이용이 상충하는 도시하천의 어메니티 향상을 위한 기준은 마련되지 않고, 일부 하천에서 이용과 관리의 효율성을 고려하지 않은 무분별한 개발을 부추기게 되어, 오히려 어메니티 향상의 측면에서는 부정적인 결과를 초래하였다. 따라서 본 연구에서는 하천 특성에 적합한 어메니티 도입 기준을 설정하기 위하여 하천의 규모, 자연도, 이용지수를 기준으로 하천유형을 분류하였으며, 이를 바탕으로 지속적인 연구를 진행하여 선진사례와 국내하천조사를 통해 지표요소를 분석하고, 분석된 지표요소에 따라 유형을 추출해내는 과정을 통해 하천유형과 활동유형, 도입시설간의 관계를 설정하여 도시하천 어메니티 향상을 위한 기준으로서 하천복원모델(안)을 제시하고자 한다.

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.
