To meet with the nation's policy of Green Growth, local governments are rushing to propose an ecological urban development plan. And although various studies stress on the need of ecological planning to harmonize development with preservation, we have come to a point in which a quantitative evaluation of how much ecological planning contributes to the environmental load is needed. Through the increasing tendency of making plans based on the development of IT technology, capability of gathering environmental data and scientific instrument, studies on ecological planning's effect towards environmental load has recently begun. This study aims to perform a quantitative evaluation on how ecological planning mitigate urban heat island in the region of Namyang-ju Wallsanli. Three theories were used to mitigate urban heat island ; White network, Green network and Blue network. As a result, the atmosphere temperature was reduced the whole site $1.1^{\circ}C$ and partly $7^{\circ}C$ and the mean radiant temperature was reduced the whole site $1.1^{\circ}C$ and partly $8.7^{\circ}C$ on the modified ecological landscape plan in summer. The PMV index is 0~1 in ecologically modified landscape plan otherwise almost 3 in landscape plan. This study has its limits on the fact that results may differ from the actual plan as the study was performed based on the land use plan and building plan. However, what is important is that it shows a quantitative result of the effect that ecological planning has on surrounding environment and reducing environmental load.

The progress made by scientific development achieved the goal for making human environment convenient and functional. However, it also caused excessive expanse of artificial environment, which in turn produced undesirable segregation between human and nature. Recently we frequently see ecological space designs which try to be synchronized with nature not only in technological terms, but also in psychological terms. This paper examines various viewpoints for ecological space design. First, it studies philosophical backgrounds of ecological space design through comparative analysis between eastern and western ideas of nature. Then it classifies the types of viewpoints for ecological space design with supporting explanations from scientific proofs. Finally, it provides case analyses for each of these views. This research aims at proving the value of ecological space design so that it can guide future direction of space design toward reestablishing the organic relationship between human and nature.

This purpose of this study was to investigate the influences of environmental education through ecological art education focused on music drama, on the environmental sensitivity of 5th graders in an elementary school in Seoul. A reconstructed questionnaire through Kim(2008)'s test tool was used to the effects of applying an ecological art educational program. The SPSS program was used to analyze the results. The major results of this study are as follows. First, the researcher was able to develop and apply a professor-learning model for the environmental education using the ecological art education focused on music drama by extracting and recreating environment related contents from the 5th grader curriculum. Second, this program had a positive effect on elementary students' environmental sensitivity. Third, according to qualitative results, students appear to be more concerned and interested in the environment and environmental problems in their daily lives. In conclusion, the ecological art program focused on music drama has a positive effect on increasing the environmental sensitivity of 5th graders. Therefore, more intensive research should be conducted, linking teaching and learning methods, as a follow-up activity.

Textile and pigment wastewater samples collected from an industrial complex showed toxic effect on Daphnia magna. For textile wastewater, 48 h acute toxicity of effluent was not detected while toxic unit (TU) of influent was 1.79. The toxicity of influent was completely disappeared by gamma-ray treatment at 10 kGy or by suspended solids (SS) removal. In case of pigment wastewater, both influent and effluent were toxic to D. magna though the effluent satisfied current water quality standards. Gamma-ray treatment had little effect on the toxicity reduction of pigment wastewater since the toxicity was mainly caused by metal ions, in particular, Cr(VI). This work suggests the bioassay technique for monitoring adverse effects of wastewater should be introduced, and also shows the usefulness of gamma-rays as an advanced treatment technique for textile wastewater.

The goal of this study is to investigate the effect of ecological experience program at the urban stream on the environmental sensitivity of elementary school students. In order to perform this study, two classes of 6th graders of M elementary school in Gwangju were selected and divided into two groups; one groups was the experimental group that undergoes ecological experience program at the Gwangju River, and another group was the control group that studied about environment in the classroom. The results of this study were as following. First of all, the experimental group has more influence on the environmental sensitivity than the control group. Secondly, the ecological experience program at the urban stream can be the effective method to build the environmental sensitivity of elementary school students. In conclusion, the results are showing that the ecological experience program at the urban stream helps elementary school students to change their environmental sensitivity in positive ways, also it gives idea that how to protect the environment and what they actually can do.

Heavy metal contamination and biological toxicity of mine drainages and sediments in abandoned mines were studied. Mine drainages had pH at a range of 2.94~7.86, and contained heavy metals at a toxic level. For coal mines, toxicity of mine drainage to Daphnia magna was attributable to acidic pH. In addition to the low pH, suspended heavy metals such as Zn and Cu contributed to toxicity of mine drainages at abandoned metalliferous mines. All mine sediments studied in this work showed biological toxicity to Chironomus riparius, having mortality at a range of 15~60%. However, its relationship with physicochemical properties including heavy metal content of the sediments was not statistically explained. Exceptionally clay ($< 2{\mu}m$ particle) content was negatively correlated with the biological toxicity for sediment samples collected at the same abandoned mines.

Environmental problems in urban spaces tend to result from excessive use of resources faster than the ecosystem can recover itself. In order to address this problem, city or municipal governments tend to devise plans and policies to lead development within their ecological carrying capacity. This study computes ecological capacity of Asan city, Province Chung Nam, South Korea through applying the concept of ecological footprint. This study finds ecological footprint and deficit of Asan city in 2015 were 5.12 and -4.99, respectively. From 2001 to 2015, Asan city experienced not only an 81% increase of ecological footprint, but also a 190% increase of ecological deficit. Such results suggest that Asan city has experienced a steady increase of resource consumption due to population increase and urban growth, indicating that loss of ecological spaces such as green space, farmland, wetland and so on restoring the ecosystem has been accelerated. Therefore, in order to promote sustainable development, Asan city should not only protect green space, farmland, wetland, and so on but also create urban growth plans and policies taking into account its environmental capacity of the city. This study provides suggestions for Asan city to lead urban growth within its environmental capacity by applying ecological deficit.

With expansion of modern cities, a huge number of old industrial facilities have been abandoned. Thus, in the development of ecological city, this study aims to conclude on these old facilities and their ecological landscape designs by analyzing successful cases. The approaches adopted are as follows. Starting with literature review, whereby old industrial facility's definition and developing process are pinpointed, the paper studies representative cases with reuse and re-development theories of ecological design for old industrial facilities, of which renovation types, reuse effects, and design features are particularly examined. Case studies also demonstrate considerations in ecological reuse designs, such as ecological restoration, energy conservation, rainwater collection, and utmost pollution reduction, etc. However, technology, environment and circumstance differences determine that each design project requires concrete analysis, which should also be considered in future ecological design for old industrial facilities.

This study aims to find out the way of revitalizing of natural riverfront space in terms of ecological aspect. At the first part, theoretical made in terms of concept, planning aspects and techniques which were main bases for the study. It begins by explaining the concept of ecological riverfront space, the main aspect and techniques of its planning. After this, it analysis eight cases(four cases in Korea, Swiss, Germany, America and Japan) in terms of the objects, planning techniques and the results of development. It continues by making detailed analysis according to four objectives like 'protection from flood', 'quality of the river', 'ecological preservation' and 'active usage of riverfront space'. It ends by evaluating the relationship between objectives and the planning which will be adapted to the future development of riverfront space with ecological aspect. In conclusion, hereafter will propose desirable design-direction for revitalization about riverfront space about ecological aspect design in urban.

After UNECD(United Nations Conference of Environment and Development) in 1992, ESSD (Environmental Sound and Sustainable Development) is an important concept of urban planning in Korea. The introducing environmental assessment system of urban planning and the district unit planning system were representative cases. In this process, Landchaftplanung(ecological landscape planning) was introduced from Germany. This study was executed for applying ecological landscape planning to Eunpyung New Town in Seoul city, and analyzing the problem to apply this system. The process of ecological landscape planning was followed to (1) the site survey, (2) the analysis and assessment of survey data, (3) the establishing ecological landscape planning. Three master architects participated in all investigations. The major fields of them were landscape architecture, architecture, and urban planning. Master Architects helped many aspects. In conclusion, ecological landscape planning was feasible to be applied to develop other New Town in Korea. However the mediation system is very weak, if different situations are confronted with ecological landscape plan and land use plan in the operative legal framework of Korea. Thus, the legislation of mediation system is necessary for an establishment of ecological landscape planning.
