Korea and China can find the common feature derived from the mutual cultural exchanges, belonging to the same cultural sphere of the East Asia. It also applies to the stone figures of the palace gardens of both countries. In case of Korea in the stone figures of the palace gardens, there are few of them existing in Kyungbok Palace, Changduk Palace, and Changkyung Palace of the Chosun Dynasty, and most of them were washed away, there are hardly any records remaining and transmitted, and there are hardly any materials of drawings and pictures of them. On the contrary, in case of China, although there are those washed away, there are vast numbers of real objects, and records and materials of them. Therefore, for the study on the stone figures of Korea, the method to analogize the research lacking regarding the stone figures of the palace gardens of Korea from those of China after conducting the comparative study between those existing and those of China, may be available. I consider that although the restoration of the palaces of Chosun Dynasty of Korea had been the restoration project oriented toward the buildings until now, it will be the phase where one should have more interest toward the restoration of the palace gardens in the future, and that the restoration of the palace gardens should be made centered on the landscape architectural structures, deviated from the restoration project attaching weight to the restoration of the trees. Above all, I consider that the interest should be turned to the restoration of the stone figures where the view toward the nature of the Orientals are expressed well. For the restoration of the stone figures in the Changduk and Changkyung Palaces, it is considered that the restoration of the rough locations and shapes is possible based on the Dongkwol Drawings being transmitted, and that the research on the shapes, characters, pedestals, characteristics, etc. of the specific stone figures is possible as far as it is based on the study of the stone figures of the palace gardens of China.

Before 2022, there was a lot of confusion in the process of planning and implementing the projects for ecological restoration of the stream due to dualization the principal agent of stream management. Because the Ministry of Environment took charge of the project in 2022, securing the health of aquatic ecosystem of stream became an essential factor in the project. Therefore, in this study, the streams that require the project for ecological restoration was selected in Han River estuary, where it is essential to secure the health of the stream aquatic ecosystem as blackish water zone and Ramsar wetland are located. Physical, chemical, spatial/humanistic, health of aquatic ecosystems evaluation indexes were calculated based on the detailed facts and figures of the project for ecological restoration of the stream in the beginning. Ranking, re-scaling, z-score, and t-score normalization methods were applied to the calculated evaluation index, and the values were compared and analyzed. After that, the entropy weight method was applied to each evaluation index. Through this process, the streams(Mokgamcheon, Anyangcheon etc.) that require the project for ecological restoration were selected for the purpose of securing the health of the aquatic ecosystem in Han River estuary. The result of this study can be used as basic research data in the process of selecting the priority determination of the projects for ecological restoration of the stream.

The Youngsan River Restoration Project(YRRP) is to bring back the original appearance of the stream and to create a new waterfront. This project, which id part of the Four Major Rivers Restoration Project, began in 2009, and Juksan and Seungchon beams was completed, and waterway of Youngsan river also was constructed. Both sides of the river, bike trails, waterfront park of 70 places, including the composition and the amenities were installed. The purpose of this study is to analyze the useage behaviors and satisfaction on visitors of waterfront parks in Yeongsan River. Many visitors visit waterfront in order to walking and biking, there were many people who visit family and hobbyists club units. Visitors showed a relatively high level of satisfaction about the waterfront in the new composition such as bike trails, walking roads, and ecological parks created by the YRRP. However, the major problems was the lack of amenities in the waterfront.

In this study, changes in the fluvial landforms of the Yeoju section of the Han River, which was made up of the Han River Restoration Project, were examined through existing previous research data, government's environmental impact assessment data, satellite images, and field observations. For example, In the vicinity of Dori Island, the most upstream part of the study section, the location of the confluence of the Han River and Cheongmi Stream was changed, and it was found that a significant portion of the sand sedimentary layer disappeared. In the Bawuinupgubi area, the wetland, which is the first class in the ecological nature, was greatly modified, and the elevation of the ground rose as Gangcheon island and it was completely separated from the river by dredging The confluence of Geumdangcheon and the point bar of Yeonyang-ri in the south were also dredged, turned into an artificial waterfront park, and a chute channel remained in the form of a wetland was also developed as a recreational park. The deposional forms around Baekseok-ri islands also disappeared as dredging was carried out. Among the areas adjacent to the confluence of Bokcheon and Yangchon-ri Island, some sedimentay forms remains, but the abandonned channel between Yangchon-ri and the northern river bank has been changed into a riverside reservoir through dredging and embankment construction, and the waterway of the tributary river(Yazoo) has been greatly changed.

The Four Major Rivers Restoration Project of is the multi-purpose green growth project in South Korea. Some of the project was progressed by K-water and was declared complete on October 21, 2011. The Four Rivers Restoration Project of Korea was designed to be a packaged project that aims to resolve water-related problems such as floods and droughts and revitalize Korean public spaces near the water. K-water have applied the latest ICT(Information and Communication Technology) for the operating management of 4 Rivers Project facilities. We also have applied ICT for integrating drinking water production facilities. Applying these ICT, we have many experience for integrated water resources management, so we proposed. The first is that the big data collected should be analyzed for making decisions and taking actions while considering multiple viewpoints of how water should be managed. The second is that the new MMI(Man Machine Interface) program should be developed to use domestic needs and promote ease of maintenance for the integrated operation. The third is that the standardization of communication protocol is needed for seamless communication between equipments.

Earthquake disaster frequently happens in Shizuoka Prefecture and it is commonly predicted that a giant earthquake(Tokai Earthquake) could occur in the near future. When a giant earthquake happens, extensive damage of lifelines will be expected. It is considered that the collection of damage information and the establishment of a communication network system are very important in order to restore lifelines quickly. And geographic information system(GIS) might playa very important role to grasp the spatial information of lifeline damage in a natural disaster. The authors' group had a research project to study a lifeline restoration support system with image processing and ad hoc networking in a natural disaster. The objectives of this presentation are to introduce our project and to show some results of our study. The authors finally constructed the GIS for the integration of damage information acquired by image processing and ad hoc networking.

This study is to propose development direction of sang-dang mountain fortress toward the utilization of historical and cultural heritage as tourist attraction through the consideration of problems on sang-dang mountain fortress development. First of all, the historical significance, development project and status of Sang-dang mountain fortress was figured out. Furthermore, using pattern and general user's view was understood through the questionnaire survey then research on the actual condition of traditional korean village was performed. The ongoing development project focusing on restoration of cultural properties to its original state through an archaeological excavation investigation turned out to be lack of consideration on the utilization of sang-dang mountain fortress such as tourists inducement. Furthermore, the measures on traditional korean village which has been a problem by forming commercial area recklessly have been left off. Therefore, additional development plan is required on convenient and amenity facilities and rest places for visitors including environment improvement of traditional korean village based on the development for the restoration of cultural properties to its original state.

Rapid population growth and land use changes have severely degraded streams across the United States. In response, there has been a surge in the number of stream restoration projects, including stream restoration for mitigation purposes. Currently, most projects do not include evaluation and monitoring, which are critical in the success of stream restoration projects. The goal of this study is to review the current status of assessment methodologies and restoration approaches for streams in Virginia, with the aim of assisting the restoration community in making sound decisions. As part of the study, stream restoration projects data from a project in Fairfax County, Virginia was assessed. This review revealed that the stream assessment methodologies currently applied to restoration are visuallybased and do not include biological data collection and/or a method to incorporate watershed information. It was found from the case study that out of the twenty nine restoration projects that had occurred between 1995 and 2003 in Fairfax County, nineteen projects reported bank stabilization as a goal or the only goal, indicating an emphasis on a single physical component rather than on the overall ecological integrity of streams. It also turned out that only seven projects conducted any level of monitoring as part of the restoration, confirming the lack of evaluation and monitoring. However, Fairfax County has recently improved its stream restoration practices by developing and incorporating watershed management plans. This now provides one of the better cases that might be looked upon by stakeholders when planning future stream restoration projects.

Soil and micro-climatic environmental monitoring was conducted to evaluate the factors causing tree growth impediments at the Baekdudaegan ecological axis restoration project site. As a result, it was found that the nutrient supply was insufficient in the restoration project site due to the lack of organic matter, total nitrogen and cation exchange capacity of the soil compared to the surrounding forest. After the completion of the restoration, the soil moisture in the autumn decreased more than 7 times faster than that of the surrounding forest, and it was evaluated that the soil moisture was significantly low due to the lack of silt and clay content. In the case of the restoration site, the annual potential evapotranspiration was analyzed to be 975mm, which is approximately two times higher than that of the surrounding forest. The soil moisture of the restoration site in the summer decreased rapidly during the daytime when the amount of insolation increased and this was found to be strongly influenced by the increase in potential evapotranspiration. In order to improve the above factors affecting the tree growth at the Baekdudaegan ecological axis restoration project site, it is necessary to induce the smooth supply of nutrients and water to plants by improving physical proprieties and cation exchange capacity, i.e., using litterfall, humus soil, soil conditioner and organic fertilizer. The results of this study are expected to serve as basic data for the design, construction, and management of ecological axis restoration projects in the future.
