For waste water treatment, artificial wetland was constructed in 1998. The size of artificial wetland is 20m
200m, with sand and gravel as media and Phragmites japonica was implanted. The removal rate of BOD, TN, and TP were 86%, 33% and 25% from June 2004 to November 2005 respectively, while those were 88%, 38% and 55% in 1999. Organic materials and nitrogen compounds are still effectively removed, after 6 years of construction, but the removal efficiency of phosphorus compounds is reduced. So for sustaining of artificial wetland as waste water treatment system, the removal efficiency of phosphorus compounds must be elevated.

This study was surveyed to know changing flora between pre and post of restoration in cheonggyechon. As results, it was surveyed families 33, species 94 in 2003 and families 39, species 156 in 2005. In 2006, it was surveyed families 38, species 171. This result shows that cheonggyechon is unstable initial condition in restored stream ecosystem. Also, Naturalized species was 19 species in 2003 and it was respectively 44, 46 species in 2005, 2006. Hazard species of ecosystem was in common 3 species in three surveys. Recently, as time goes by, introduced species are increasing. And succession has mainly been progressed by one year or binary herbs. To administer restored stream ecosystem, monitoring is essential. Therefore, continuous monitoring about Naturalized species and Hazard species of ecosystem is also very important. Further, Because change of vegetation on pre and post of Restoration in Cheonggyechon Stream is very important, Monitoring will have been surveyed continuously.

The purpose of this study was to investigate how the landscape characteristics and the physical factors of landscape would affect the preference for the Gapcheon in Daejeon Metropolitan City. The Gapcheon was divided in three sections of the outskirts, Expopark areas, and residential complexes. After selecting seven landscape points where the sections could be expressed best, photographs were taken both in the upstream and downstream direction. The questionnaire used to evaluate the river's landscape included 20 items of adverbs that described the form of the river and one item to rate the overall preference. By analyzing the 14 pictures taken, the occupancy rates of the landscape elements in terms of the sky, river, vegetation of the river, mountain, and artificial structures. Image factor analysis was conducted for each of the sections in order to analyze the landscape characteristics of the Gapcheon, and then regression analysis was conducted in order to analyze the relationships among the physical factors influencing the preference of the landscapes. The results were as follows : Factors that compose the visual characters of urban river were classified be the aesthetic factor, the emotional factor and the situation factor. These 3 factors showed a 65.8% total variance. The river landscape with the biggest preference was the one from the Daedeok Grand Bridge as the occupancy area of the mountain, sky, and river was large and distributed evenly and the vegetation of the river was in a good harmony with the surroundings. After carrying out regression analysis to examine the relationships between the visual preference of Gapcheon and the physical factors of landscape(the sky, river, vegetation of the river, mountain, and artificial structure), the following regressions model was made : PRE=5.906+0.017(river)-0.053(artificial structure)-0.060(vegetation of the river) (R-square=0.48).

Journal of the Korea Society of Environmental Restoration Technology, volume 10, issue 3, 2007, Pages 38~51
The purpose of this study is to analyze of biotope types and to develop assessment for forest ecosystem evaluation method. Vegetation types divided into 27 types. Considering the vegetation types, vegetation structures, DBH, potentials, and disturbance, it was decided to apply 58 biotope types and survey site's biotopes were divided into 24 biotope types. Assessment indicators were naturaliness, diversity, rarity, stability, potential, and disturbance. The areas given the first grade in ecological value included 9.2% of the site's total land. Areas with the second grade accounted for 43.0% of the total land. Areas with the third grade made up 47.8% of the site and mostly they were areas with dominance of fired area and artificial forest. To plan to build naturally-development for Site, there should be plans to conserve areas with the first grades. For the areas with the second, and third grades, plans for ecological land use based on conservation and restoration in terms of securing biodiversity are needed.

Green space infrastructures for three cities, Gwacheon, Uiwang, and Hanam, were analyzed in terms of the area of urban parks per capita, the percentage of green space area, the area of green space per capita, and the percentage of vegetation cover in residential area, etc., which are commonly used as criteria for urban green space planning. The differences in green space infrastructure among these three cities were compared to the satisfaction level of residents for their green space. The area of parks per capita corresponded to the satisfaction level when Seoul Great Park in Gwacheon and Misa Park in Hanam were not included. Although these two huge parks accounted more than 90% of the area of urban parks in Gwacheon and Hanam, they serve more people from outside the cities and not likely visited by residents due to lacking of daily accessibility. The percentage of vegetation cover in residential area were considered to affect the satisfaction of residents for green space, whereas the total area of green space or the percentage of green space area in the cities was not related to the satisfaction level. It suggests that the distributions and accessibilities of green space and park service are more important for satisfaction than total green space area indicating urban sustainability.

Journal of the Korea Society of Environmental Restoration Technology, volume 10, issue 3, 2007, Pages 88~99
This study is aimed to suggest a direction for the general environment education through analyzing current environment education curriculums and survey of educational needs for students in Korean universities. Since the result of this survey shows that most university students lack experience in environmental education in their secondary education, the basic educational programs as well as advanced educational programs should be included to develop a general environmental education curriculum for university students. So far, general environmental education for university students has not witnessed a clear and distinct object and direction. Since we live in a situation where environmental problems should be considered in every aspect of our society, the general environmental education curriculum for university students shall play a role to solve these problems. Additionally, we need to change the way of environment education from educating and raising the environment professionals to educating and raising people who comprehensively understand economy, society and environment under the sustainable development paradigm. Also the focus of environmental education should swift from natural science to over all perspectives. Recently, the need of interdisciplinary curriculum for the environment education field has been discussed in universities. However, it has not been integrated into the normal curriculum. In this regard, systemic improvement which enables general education curriculum to operate flexibly will be followed. The key to establish an interdisciplinary curriculum is a flexible educational curriculum system which can solve problems arising from departmental curriculums, and promptly respond to the demand of educational and social consumers. Additionally, the result of survey shows that students want diverse educational operations and teaching methods, equipping educational assistance system for these needs will be required.
