This work was designed for the Green Fund Aid 2004 of Korea Forest Service. It won the prize and has been constructed. We can have an opportunity to play a leading role in improving partnership with participation of local communities, promoting environmental education, and enhancing the environmental quality by constructing biotops in urban areas where energy flow in the ecosystem is not balanced. This design includes 'citizen participation process' and 'local community partnership' that is expected to promote local community participation in the process of design. This work suggests that biotope construction with citizen involvement and community partnership plays an important role not only in design items but also in the revitalization of local community. This sort of design process could not be fully achieved without cooperation with stakeholders - environmental specialists, local authorities, relevant societies, schools, teachers, parents of students.

A long-term nationwide nonpoint-source pollution monitoring program was initiated by the Ministry of Environment Republic of Korea (ME) in 2007. Monitoring devices including rain gauges, flow meters, and automatic samplers were installed in monitoring sites to collect dynamic runoff data in 2008-2009. More than 10 rainfall events with three or more antecedent dry days were monitored per year. More than 10 samples were collected and analyzed per event. So far, five land use types (single family, apartments, education facilities, power plants, and other public facilities) have been monitored 23 to 24 times each. Characterization of the runoff from different land use types will aid unit load estimation in Korea and hopefully in other countries with similar land use. The monitoring results will be reported regularly at national and international levels.

The resulting rapid urbanization in the several decades caused increasing residential mobility. The purpose of this study is to analyse systematically the effects of residential mobility on the family quality of life and the factors that cause residential mobility. For this purpose, 976 housewives were sampled from the households in Seoul. The data were analysed by such statistical methods as multiple regression, crosstabulation, ANOVA test and path analysis. The main results obtained are as follows; 1) A significant proportion of the urban households are experienced frequent residential mobility. 2) Among the factors that affect residential mobility, the most important factors are family income, tenure type, and residential satisfaction. 3) Residential satisfaction is an important intervening variable in residential mobility. 4) It has been observed that family quality of life was affected by residential mobility patterns. Analysis has revealed that quality of life de eloped remarkably by changing for residential location, especially in education environment for their children.

With the recent spread of the concept of Smart Cities which is to solve urban problems with ICT technology, Living Lab, which identifies the demands of citizens who dwell in the city and verifies the acceptability of the services being introduced, has become an important topic. Living Lab is an open innovation platform introduced in consideration of the user's perspective in real life and is a new approach in that service developers use collective intelligence in the process of Co-creation with users. Living Lab is operated on topics which is close to citizens' daily lives such as energy, housing, transportation, and education. In particular, as energy and environmental-focused Living Lab emerges in accordance with the 'Korean New Deal Policy', interest and importance in the field are increasing. The paper derives the characteristics of water resource Living Lab through case analysis of several Living Lab practices. Water resource Living Lab in Daejeon and Chuncheon, which are located in Korea, and water resource Living Lab in Romania and Indonesia are covered in this paper as the reference. The paper finally analyzes the case of Sambang Water Living Lab in Gimhae, which is the city located in southern part of Korea. As a result of case analysis, the urban water resource Living Lab focuses on the raw water of urban water resource and should respond sensitively to the safety of citizens. And for the success of this urban water resource Living Lab, it is essential to ensure that citizens participating in the Living Lab clearly understand the concept of water resources, and citizens' opinions to be implemented as services.

Shield tunneling method is widely used to build tunnels in complex geological environment. Stability control of tunnel face is the key to the safety of projects. To improve the excavation efficiency or perform equipment maintenance, the excavation chamber sometimes is not fully filled with support medium, which can reduce the load and increase tunneling speed while easily lead to ground collapse. Due to the high risk of the face failure under non-fully support mode, the tunnel face stability should be carefully evaluated. Whether compressive air is required for compensation and how much air pressure should be provided need to be determined accurately. Based on the upper bound theorem of limit analysis, a non-fully support rotational failure model is developed in this study. The failure mechanism of the model is verified by numerical simulation. It shows that increasing the density of supporting medium could significantly improve the stability of tunnel face while the increase of tunnel diameter would be unfavorable for the face stability. The critical support ratio is used to evaluate the face failure under the nonfully support mode, which could be an important index to determine whether the specific unsupported height could be allowed during shield tunneling. To avoid of face failure under the non-fully support mode, several charts are provided for the assessment of compressed air pressure, which could help engineers to determine the required air pressure for face stability.

The purpose of this paper is to analyze the influences of extreme flood on urban stream's habitat environment at Shincheon stream in Daegu. In case of Shincheon stream, as any extreme floods have not flowed over the artificial bank, an extreme flood have an effects on inner part of confined channel. To make riparian park along Shincheon channel, Concrete and rubber weirs are constructed. These weirs interrupted flow of running water as obstacles during extreme flood, and running water moved aside into and destructed banks of lower-flow-channel. In reach of no weir, as all small-scale topographic bedforms were eliminated, habitat environment of river ecosystem was simplified, and biodiversity of river ecosystem was decreased. As simplified riverbed become irregular bedforms through frequent small-scale-floods, river ecosystem will become vigorous.

This study proposed a prediction equation for the estimation of blasting vibaration and blasting noise, utilizing 320 datasets for the blasting vibration and blasting noise acquired during urban blasting works in the Incheon, Suwon, Wonju, and Yangsan regions. The proposed blasting vibration prediction equation, derived from regression analysis, indicated correlation coefficients of 0.879 and 0.890 for SRSD and CRSD, respectively, with an R² value exceeding 0.7. In the case of the blasting noise prediction equation, stepwise regression analysis yielded a correlation coefficient of 0.911 between the prediction values and real measurements for the blasting nosie, and further analysis to determine the constant value revealed a correlation coefficient of 0.881, with an R² value also exceeding 0.7. These results suggest the feasibility of applying the proposed prediction equations when environmental impact assessments or education environment evaluation according to urban development or apartment construction projects is performed.

Citizen participation or resident participation is perceived as an effective way to correspond to the diverse urban problems, especially in the area of residential environment improvement projects and community activities. As the leading city of the Honam region and a core middle city leading the development of the southwestern region, Gwangju city is planning and under-developing new Housing Complexes and Urban Renewal Projects. The purpose of this study is to identify the perception of Gwangju citizens on resident participation in community activities to suggest diverse strategies for improving quality of citizen's life and making better living environment. For the research purpose, 1,380 questionnaires were distributed to the Gwangju citizens who live in 5 autonomous districts -Dong-gu, Seo-gu, Nam-gu, Buk-gu, and Gwangsan-gu- and 601 were used in data analysis. Although citizens in Dong-gu showed the lowest settlement consciousness, they required the highest level of need for resident self-help activities. Contrastingly, Seo-gu showed the highest level of settlement consciousness and the lowest need for resident self-help activities. Based on the results, high quality community facility should be provided to promote residential satisfaction and consciousness of residential participation and self-help activity must be improved. And also, diverse strategies for resident participation including development of resident education programs and search for regional resources should be covered in further research.

National park, as a natural park, has a dual purpose, to promote both protection and enjoyment. The educational activities of the national park can be partly understood as one of the appropriate means to balance its double purposes. This study provides a review of environmental education in the US National Parks according to social transition. Taking historical perspective and case studies, environmental education has played roles in helping the balance between preservation and enjoyment. Since the environmental movement, environmental education goals, particularly understanding the natural processes observable at national parks, has become more a part of the interpretation and education missions of the parks. Also non-governmental and non-profit partners have played important educational-based roles in support of both the National Parks Service and environmental education goals. The two different models also differ in the public's perception of them. Federal employees are resented in some rural areas in the U.S., but the general population automatically attributes authority, friendliness, and national-interestedness to NPS Rangers. This may in turn limit how strongly such staff could serve as strong advocates for the environment. On the other hand, the non-profit may be seen by some as strongly liberally biased and associated with urban wealth. It is also not as universally recognized as the NPS. It can, however, go far to develop new partnerships and undertake public relations. Non-profits vary greatly in quality, also affecting public perception.

Purpose: The aim of the study is to provide information about selecting school sites for new schools in congested urban areas and to propose a method to manage harmful environments around primary and secondary schools. Method: Four schools were selected around Gilum New Town and Ilsan City. The problems were identified by counting the businesses classified as harmful and prohibited in a school zone through surveying, collecting reports from relevant sources, and asking questions of authorities in school districts. Results: It was found that many harmful businesses prohibited by the Law of School Health were present in the safe zone of schools in both Ilsan city and Gilum New Town. The school site of Bohyun Elementary School was classified as poor because there was a steep ascent at the entrance and the school was surrounded by a dangerous, steep boundary. We suggested that an education and environment assessment system by completed before the school site was selected. Conclusion: There is a urgent need to improve the approval and permission process of harmful businesses as well as regulatory standards of school site selection in the light of the shortage of land.
