The past concept of constructing houses was focused on how to overcome the limitation of consuming natural resources such as energy and materials, which increased the official cost and the environmental pollution. On the other hand, the echo-friendly concept has considered the harmony between human being and nature more critically and has applied the characteristics of natural environment into a unique dwelling design by developing constructs and materials adjusted to the particular climate, making them into a unit of impacting positively the complicated system. The current environmental issue is how a dwelling adapts into a given climate in which the design is applied by ecology without damaging the natural environment. In another word, the main issue in the twenty first century will be how we meet the human needs to dwellings applied by the residential environment. Therefore, we have to provide a hospitable place for residents' mental and physical health through "Green Design", emerging as the critical design of urban collective dwellings. Based on these conceptions, the purpose of this study is to suggest the way of designing the urban collective dwelling applied by ecology, proffering wealthy life style to residents with the preservation of natural environment as applying an ecological concept into the design of collective dwellings that represent a contemporary housing type for urban residents.

Physical activities in the forest environment stimulate the parasympathetic nervous system of humans and have positive effects on the autonomic nervous system as well as moods and emotions. However, there are almost no studies on the benefits of exercise in the forest environment for patients with myocardial infarction. The aim of this study was to investigate the effects of 15-minute single session walking by myocardial infarction patients in the forest and urban environment on the physiological and psychological states. The heart rate variability was measured in 10 patients with myocardial infarction to assess physiological state after single session walking for 15 minutes in the forest environment and urban environment. In order to evaluate the psychological state, a profile of mood scale (POMS) and semantic differential (SD) questionnaire were used. The results of this study showed that 15-minute single session walking in the forest environment activated the parasympathetic nervous system of adult myocardial infarction patients more than 15 minutes of single session walking in the urban environment, and also made them feel more positive in terms of the POMS and SD. Therefore, this study suggests that even single session walking in the forest environment can positively influence the physiological and psychological states of adult heart disease patients and may also contribute to health care.

The accelerated pace of climate crisis due to continuous industrialization and greenhouse gas emissions necessitates sustainable solutions that simultaneously address mitigation and adaptation to climate change. Naturebased Solutions (NbS) have gained prominence as viable approaches, with Green Infrastructure being a representative NbS. Green Infrastructure involves securing green spaces within urban areas, providing diverse climate adaptation functions such as removal of various air pollutants, carbon sequestration, and isolation. The proliferation of Green Infrastructure is influenced by the quantification of improvement effects related to various projects. To support decision-making by assessing the climate vulnerability of Green Infrastructure, the U.S. Department of Agriculture (USDA) has developed i-Tree Tools. This study proposes a comprehensive evaluation approach for climate change adaptation types by quantifying the climate adaptation performance of urban Green Infrastructure. Using i-Tree Canopy, the analysis focuses on five urban green spaces covering more than 30 hectares, considering the tree ratio relative to the total area. The evaluation encompasses aspects of thermal environment, aquatic environment, and atmospheric environment to assess the overall eco-friendliness in terms of climate change adaptation. The results indicate that an increase in the tree ratio correlates with improved eco-friendliness in terms of thermal, aquatic, and atmospheric environments. In particular, it is necessary to prioritize consideration of the water environment sector in order to realize climate change adaptive green infrastructure, such as increasing green space in urban areas, as it has been confirmed that four out of five target sites are specialized in improving the water environment.

The research objective of this thesis aims to utilize the history and culture of cities as resources and to solve the problems of modern urban environment which can produce non-personality in the age of globalization. This study deals the Sustainable Urbanism and Architectural System in the Historical city ; First, Historic resources and its spatial characteristics. Second, reused resources and remodeling of existing building. Third, Sustaiabl design component and management process. Historic resource are not only a cultural and spatial aspects but also it have potential importance in environmental aspects. Sustainable urbanism and architectural environment are cultural resource and it can be enhanced by long term established spatial orders. In order to keep the order, rehabilitation, reuse, remodeling of urban space should be managed by various participations which concerned with the city and urban architecture. That can be say systematic approach for the sustainable environment.

Recently 3D city models are required for many applications such as urban microclimate, transportation navigation, landscape planning and visualization to name a few. The existing 3D city models mostly target on modeling buildings, but vegetation also plays an important role in the urban environment. To represent a more realistic urban environment through the 3D city model, in this research, an investigation is conducted to extract the position of trees from high resolution IKONOS imagery along with Airborne Laser Scanner data. Later, a tree growth model is introduced to simulate the growth of trees in the identified tree-positions.

Purpose: Urban heat island and Heat wave raise urban temperature and create damage of human life. Growing up as quantitative supply to solve shortage of housing, Urban residential area in Korea have a low rate of nature surface and heavily population makes temperature rise. Most houses in the declined residential area are multi-family rental housing and have many factors congesting housing environment such as narrow in-between space, outdoor staircases, walls and semi-basement floor, which make thermal environment getting worse. Most of the residents in this area are small tenants vulnerable to climate change adaptation, This damage is expected to be even greater. This study focus on multiple dwelling in urban residential area prone to temperature rise and draw temperature adaption method that can apply to multiple dwelling.

The ecosystem in the Gwangju Stream has taken a wide range of disturbance such as the discharging water of sewage treatment plant, the lake water and the river water from different water system over the past decade. This study was figured out some significant influence factors by analyzing the relationship between biotic and abiotic factors in the urban stream. Abiotic components included 15 water quality variables which were measured in five sampling sites along the stream from October 2014 to July 2015, whereas the benthic macroinvertebrates found in those sites were used to estimate various biotic indices representing the ecological status of the community. The results of correlation analyses indicated that abiotic factors by human activities affected on the inhabitation of benthic macroinvertebrates more than biotic factors. The results of cluster analyses and ANOVA tests also showed that biotic and abiotic characteristics were clearly different in season. The main influence factors of cluster analysis by sites were $NH_3-N$, EPT(I) and DO. It was considered that more various statistical analyses would be necessary to find some different relationships and influence factors between biotic and abiotic variables in the urban stream.

본 연구는 1920~1999년까지 매스미디어에 나타난 국내 도시재생의 시대적 동향을 의미연결망(Semantic-Network Analysis)분석방법을 활용하여 도시재생에 대한 인식을 파악하고, 향후 지향해야 할 정책적 시사점을 예견하는데 목적이 있다. 분석 결과, 시대별로 기사수가 증가함에 따라 사회적 현상과 이슈의 상호관계가 복잡하게 얽혀서 도시재생의 의미가 형성되어 온 것으로 분석되었다. 전반적으로 '도시'와 '재생' 키워드도 시대별로 등장 빈출이 다르게 나타났는데, 특히 도시개발이 심화되는 1970년을 기점으로 '도시'와 '재생'이 밀접하게 관련되어 나타나는 것으로 분석되었다. 시대적 변천에 따라 '도시'는 1990년도에 이를수록 등장빈도가 높게 나타났으나, '농촌'의 등장빈도가 급격히 하향하는 것으로 분석되었다. 이는 1990년대까지의 도시문제 해결 정책의 부작용으로 나타난 슬럼화 및 침체 현상이 대부분 도시에 집적되어 있었으며, 재생에 있어서 농촌보다 도시의 물리적 환경을 개선하는 목표 중심으로 정책적 논의가 진행되었기 때문으로 해석된다. 1970년대 이후 '개발'과 '재생'의 키워드 분포가 양적 증가 추세를 보이는데, 도시의 외연적 성장을 위한 개발로 인해 도시의 양극화 현상은 두드러지게 나타나 결국 환경적 위협의 가속화를 초래했던 시대적 상황과 인식이 같은 흐름을 보이는 것으로 나타났다. 특히 '재생'의 키워드는 주로 환경문제와 직결되는 쓰레기, 폐품, 오염, 공해 등과 같은 키워드와 연관되어 등장하였는데, 이러한 환경문제의 대두는 1980년대 이후 지속가능성에 대한 관심, 환경 및 생태 친화적 기술과 분야의 발전을 촉진시키는 계기가 되었다. 도시재생과 관련하여 허브 역할을 수행하는 키워드로 '도시', '재생', '환경'의 등장 빈출이 1990년대에 이를수록 증가하는 것으로 나타났는데, 이는 도시재생의 촉발이 사회문제로 제기되었던 '환경'과 밀접한 관계가 있음을 시사한다.

Automobile emissions have caused a major hydrocarbon pollution problem in the ambient air of many cities around the world. This study was conducted to measure the pollution status of volatile organic compounds (VOCs) in some urban residential areas in Seoul, Korea. A total of 20 VOCs (11 aromatic and 9 chlorinated species) were identified at 4 urban residential sites in Seoul, Korea from February 2009 to July 2009. Comparison of total VOC (TVOC) concentration data indicated the dominance of the aromatic species with the maximum (72.2 ppbC) at Jong Ro (JR) and the minimum at Yang Jae (33.4 ppbC). The peak concentration of TVOC occurred during spring at all sites with an exception at Gang Seo (GS), where it was recorded during winter. The distribution of individual VOCs at the study sites was characterized by high toluene concentration. A strong correlation of benzene was also observed with other VOCs and criteria pollutants at all sites (except YJ). The overall results of this study suggest that vehicular emissions have greatly contributed to the increase in VOC pollution at all the study sites.
