본 연구는 동시대에서 요구되는 재생적 환경특성을 고려하고, 지속가능한 정원디자인을 실현하기 위한 개념적 바탕과 적용의 기초를 마련하는 것을 배경으로 한다. 그러므로 본 연구는 로빈슨의 자연주의적 가치관으로부터 영향을 받은 클레망의 정원이론에 대한 개념을 이해하며, 클레망의 정원에 구현된 자연주의적 차별특성을 로빈슨의 와일드가든과 비교하였으며 결과는 다음과 같다. 첫째, 클레망에게 있어서 정원디자인을 한다는 것은 식물의 움직임에 의해 형성되는 공간에 대한 과정의 미학으로 대상지에 정착하여 가는 생태적 프로세스를 포함한다. 그러므로 '움직이는 정원'을 실현한다는 것은 자연에 대한 신뢰를 바탕으로 자연에 순응하고, 식물들의 종자가 계획되지 않고 자연스럽게 적절한 생육환경을 찾아가도록 허용해야 하는 가능성을 디자인하는 것이다. 둘째, 야생(Wild)에 대한 가치관은 미시적 관점과 거시적 관점으로 구분되며 각각의 표현특성을 지니는데, 로빈슨의 경우 소규모의 정원으로서 기존 공간에 대한 연화(軟化) 기능을 담당하며 종속적인 특징을 가진다. 반면 클레망의 정원은 공간의 주체로서 거시적 안목에서의 전략이며, 생태적 역할의 중심이 되는 인프라스트럭쳐로서 구체화된 하향식 접근 특성을 가진다. 셋째, 로빈슨과 클레망의 정원에 대한 공간운용 관점은 자연의 자율성과 정원의 야생에 대한 불가분의 관계를 인정하며 자연에 대한 보존이 성립되어질 때 우리가 원하는 삶과 공존할 수 있다는 가치를 전달하며, 그들의 정원은 환경결정론의 관점을 바탕으로 식물이 매체가 된 환경가능론적 논지와 생태학적 입장의 중재로 유추된다.

본 연구는 쓰레기 매립지의 생태학적 복원에 필요한 토양환경자료를 제공하고자 경기도 지역의 10개 쓰레기 매립지의 복토층 토양과 주변토양의 이화학성을 조사하였다. 매립지 토양은 염류집적에 의하여 주변토양 보다 pH와 전기전도도는 높았으나, 유기물 및 전질소 함량은 낮았다. 매립지 토양은 식물체 필수성분 중 특히 질소와 인산의 함량은 낮은 것으로 나타났다. 토양의 교환성 양이온 함량은 매립지간 차이가 컸으나 매립지 토양이 주변토양에 비하여 높은 경향이었다. 토양 중 중금속 함량은 매립지 인천 원창동 매립지를 제외한 모든 매립지에서 대조구보다 높게 나타났으나 모든 매립지에서 식물에게 독성을 일으킬 수 있는 임계농도보다 낮았으며, 또한 토양환경보전법의 농경지에 대한 우려기준에 비하여 매우 낮은 값을 나타내었다. 따라서 매립지 토양은 질소와 인산의 함량이 낮으므로 자연 또는 인공적인 식생을 이용한 매립지의 생태학적 복원시 질소와 인산의 시용과 같은 토양관리 대책이 필요하다고 판단되었다.

While heat island has been recognized as an unique environmental nuisance in cities, the phenomenon tends to be regarded as an inevitable side effect on urbanization. Recently the nature of the heat island has been disclosed and efforts for the remedy have been discussed in many ways. Some pioneering actions have been taken to mitigate the strength of the heat island's intensity in several countries. After studies for the heat island and speculations on current pilot policies of 3 different countries has been done, mitigation policies for heat island has been suggested as followings. 1. Preservation of natural topography is essential because latent energy consumption(evapotranspiration) from the site is the single most important factor to mitigate the energy surplus caused by urban heat island. 2. Because current national zoning ordinance or building law can not effectively control the site specific local environment, heat island policy should be established or employed at local level. 3. Incentives for the mitigation should be adopted on the process of implementation because environment is public concern. 4. Wind can easily dissipate energy surplus which is the major driving force for heat island. Therefore local wind, the direction and intensity should be sustained and sometimes facilitated fully through policies.

For the recycling of the resources and the preservation of the environment, this study's purpose is to measure flexural behavior of the reinforced concrete beams with the major variables like concrete strength, replacement ratio of the recycled aggregate and the waste foundry sand and the tension reinforcement ratio and to present the data of the recycled aggregate used for the structure design. The experiment on the flexural behavior resulted in the followings. The ultimate strength of recycled R/C beam was manipulated proportionate to the tension reinforcement ratio, however the strength instantly decreased after passing the ultimate load due to the destroyed concrete of the compression side. The deflection at the maximum load varied from the tension reinforcement ratio by 5.5 times. The test specimen with the tension reinforcement ratio less than $0.5{\rho}b$ showed constant curve without change in the load from the yield to the ultimate load in contrast to the distinctive plastic region where the displacement was rising. Although the strain of main tension steel with the reinforcement ratio indicate different, the design of recycled concrete member can be applied for current design code for reinforced concrete structure as the ratio of tension reinforcement district the under the reinforcement ration in a balanced strain condition.

Near future dynamics of water qualities (nutrient concentration) of the Han River was predicted, based on a mathematical model representing the relationship between the nutrient concentration in th river wagter and environmental factors (population density, land-use types, rock compositions and nutrient accumulation) in the basin. The population density and land-use types were forecasted to change distinctly in the downstream area, especially in Seoul City area in 1985~1990 whereas any environmental factor was not expected to change its level significantly in both upstream and middle reaches areas. It was indicated by the model that the nutrients concentration in the up- and mid-streams would keep its level in future as it was, but it would increase drastially in the downstream area. For the preservation of the water qualities in the downstream at least to keep its level as it was in 1980, practical countermeasures were proposed, based on the assessment of the contribution of each environmental factor to the water qualities.

response to the global city. It was developed to cope with the decline of the manufacturing industry, a rise in unemployment and a welfare state system in danger. In cities of the concept, there has been much change in existing urban space and accordingly wisdoms and knowledge has been accumulated. The purpose of this research is to scrutinize urban spatial modification of a regenerated model city "Bologna". The target area of analysis was a ex-factory ailing district. Field site visit, deep interview with professionals and citizens, walk through observation, and historial literature review on the site were employed. As results, its history, retrofit process and current change were systematically described. The results showed ways of thinking, attitude toward historic preservation, technology, and creativity of using existing buildings for contemporary functions. This has a significant implication on Korean urban development which mostly, has ignored the existing value of community and buildings.

This study examined the changes of water quality in relation to distribution of hydrophytes, and the purification capacity of Zizania latifolia to improve the effluent from Munpyeong stream from March 1997 to December 1999. While the concentration of nitrogen and phosphorous in water were increased during the farming season, those decreased, during the streaming down to paddy and drainage areas. In investigated sites, the Z. latifolia was dominant community according to the development of the natural wetlands. Furthermore, it formed a large community owing to its high adaptability to environmental changes in the agriculture lands. In September, the leaves productivity of the Z. latifolia were 4,032g D.W/$m^2$and roots were 7,680gD.W/$m^2$. The purification capacity of the Z. latifolia for NH$_3$-N, $No_3$-N, and PO$_4$-P were 13.41, 17.07, and 4.58 respectively during 5 days. The results suggested that it needs to establish wetlands vegetated by hydrophytes to improve the water quality of the effluent from agricultural lands.

Wetland areas have characteristics of dynamic cycling of materials in relation to land and water. Although having great potential for providing unique natural environments, they are vulnurable to human land use activities and some places are in danger of being eliminated. This study had an objective of investigating vegetation changes in Ilwol reservoir to provide basic information for the preservation and ecological restoration of the wetland area. Wetland vegetation was investigated along with the site conditions which may affect the vegetation development. There were 10 vegetation types with various species composition. Humulus japonicus, Zizania latifolia, Phragmites japonica, Bidens frondosa, Typha orientalis, Scirpus tabernaemontari, Phragmites communis, Persicaria thunbergii were the major wetland plants found at the reservoir area. Precipitation and water level were the elements mostly affecting the distribution of the plants. Phragmites japonica was closest to the water front, followed by Zizania latifolia, Humulus japonicus and Bidens frondosa. Most plant zones were predominated by one or a few species.

In this manuscript, a review of the diversity of Chinese indigenous goat breeds according to data from body stature and appearance, chromosome group, blood proteins, DNA molecular markers (mitochondria DNA, random amplified polymorphic DNA, microsatellite DNA, major histocompatibility complex) has been introduced. All of these provide efficient tools for the diversity analysis of Chinese indigenous goat breeds and are very important for biodiversity conservation, restoration of declining goat breeds, the priority defining in Chinese indigenous goat breeds' protection and the selection of nature preservation zones. Many Chinese indigenous goat breeds with small population size in the isolated mountains or reservoir areas are verging the potential threat of extinction, effectively lost with the rapid destroying of ecological environment. On the other hand, as a result of the introduction of modern commercial goat breeds and shortage of effective conservation, some populations, such as Small-xiang goat and Tibetan goat decrease rapidly in number of sires. In the interests of the long-term future of the goat breeds in China, conservation of goat breeds' genetic resources should be considered urgently and some conservation measures should be adopted. In addition, the continuing development of molecular biology will further enhance conservation of diversity of Chinese indigenous goat breeds.
