With regard to the new town developments which have supplied lots of houses in a short period of time in Korea this study aims to evaluation and finding out problems of the developments finally to suggest the direction. A new town's competitiveness model set in the previous paper takes a role of research frame to recognize the problems and to show the direction. The model explains that new town's competitiveness is composed of 4 factors; Self-sufficiency, Innovativenss, Identity and Sustainability. Problems of the developments are as follows; incongruity of spatial structure especially in the capital region, deficiency of self-sufficiency resulted from single-use development, restriction on mixed development by a number of regulations in capital region, low business value, grand scale of land compensation, house oriented planning guidance, unfair share of infrastructure fee, and physical structure depending mainly on fossil energy. Based on this recognition this study conclusively suggests corresponding direction such as role performance as a means of urban growth management, promotion of quality of life by accumulating social capital, introduction of socially sustainable management program for the new towns, discovery and creation of town's value, reexamination of self-sufficiency's meaning or target, selective deregulation of metropolitan development, institutional strategy for cost reduction, changeover from house index to urban function oriented index, and pursuit of low-carbon green town.

Cities are major sources of greenhouse gas emissions but also suitable places for implementing proactive climate mitigation and adaptation strategies. Based on the interdisciplinary review of literature, we categorize the current discussion about urban climate mitigation and adaptation planning, policy and practices into four perspectives - sustainability science, global change science, multilevel governance, and structural engineering. While these four schools of thought have distinct perspectives rooted in different disciplinary lenses, our synthesis of the literature identifies several universal themes that are common to all of the perspectives in the context of combating threats posed by climate change. The Portland case study illustrates that a city can make changes to reduce greenhouse gas emissions and increase adaptive capacity to climate change impacts by implementing smart growth, devising local climate action plans that target emission reductions in various sectors, recognizing the interactions and influences of multiple scales of governance, and supporting the installation of various green infrastructures that contribute to green economy. Furthermore, a university can serve as a hub in this climate mitigation and adaptation arena by connecting various levels of community organizations in both public and private sectors, creating innovative research centers and spatially explicit green infrastructure, designing impact assessments and campus carbon inventories, and engaging students and the larger community through service learning.

Social, economic and environmental problems caused by rapid urbanization have been recently overcome by various civic participation projects. Local governance and resident - led partnership through field - based cooperative operating systems from urban regeneration to village projects are considered success factors. Among these, the village greening project which directly affects the residents and requires spontaneity requires the role and cooperation of the various participating actors due to the sharing of public space and private space. Social capital plays a key role in the sustainability and participation of the above - mentioned business as a relational capital centered on trust and participation, network and norms. Therefore, empirical research is needed. In this study, basic research was carried out to build a formation model of social capital in participation - type greening project expanding urban green space system to living area. We analyzed the elements of participation, the components of business progress, and the factors of social capital formation through literature review and in - depth interviews with participating experts. The purpose of this study is to provide basic data of social capital formation model for analyzing sustainability and activation strategies in the future.

Due to the global climate change, the rainfall volume and frequency on the Korean Peninsula are predicted to increase at the end of the 21st century. In addition, impervious surface areas have increased due to rapid urbanization which has caused the urban water cycle to deteriorate. Green Infrastructure (GI) researches have been conducted to improve the water cycle soundness; the efficiency of this technique has been verified through various studies. However, there are still no suitable GI design guidelines for this aspect. Therefore, the rainfall scenarios are set up for each percentile (60, 70, 80, 90) based on the volume and frequency analysis using 10-year rainfall data (Busan Meteorological Station). After determining the GI areas for each scenario, the runoff reduction characteristics are analyzed based on Storm Water Management Model (SWMM) 10-year rainfall-runoff-simulations. The total runoff reduction efficiency for each GI areas are computed to have a range of 13.1~52.1%. As a results of the quantitative analysis, the design rainfall for GI is classified into the 80~85 percentile in the study site.

Rural tourism is primarily a domestic tourism activity with visitors traveling to non-urban area. Therefore, local agricultural and special products as one of rural amenity resources have been used revisitation carriers of rural tourism. For these purpose, this study selected Cheongsong-gun in Gyeongsang province, which has been famous for Cheongsong apple and planned space program on that sites as on-farm research. The sites are divided into 6 districts, agricultural production, leisure, cultural space, events or festival, green space, infrastructure for local residents and tourists. Above all, this study led local government to develop related policies using local agricultural and special products, which can be an example to plan for regional development.

In spite of the importance of the farm area in Seoul, in providing fresh vegetables, a pleasant environment and a good quality of life for residents, rapid urbanization and industrialization have greatly reduced the farm area. The purpose of this study is to examine farmers' intentions and attitudes to provide supporting data for planning the strategy of urban agricultural development. All the collected data was analyzed using the contingency tables and the Chi-square test using the SAS computer statistical package. Based on analysis of the survey data, the leaseholders were found to be more satisfied with their job than the landowning farmers. Also, the small-scale farmers with green houses showed greater job satisfaction than the ordinary large-scale farmers. Farmers' views on the farming in Seoul were different depending on their status. Therefore, agricultural strategies in there should be considered their different attitudes.

DCIA(Directly Connected Impervious Area) 및 EIA(Efficient Impervious Area)의 개념은 불투수층의 하위 개념으로서, 배수관망으로 직접 연결되어 있는 불투수층이다. DCIA는 하천 생태계의 건전성을 예측함에 있어 전체 불투수지역 자료를 사용하는 것보다 정확성이 높다. DCIA의 가장 큰 장점은 도시환경에서 녹색 사회기반시설(green infrastructure)과 밀접한 관련이 있는 것으로 알려지면서, 최근에 녹색 사회기반시설 설치에 따른 영향분석을 평가하는 중요한 요소로 자리잡고 있다. 본 연구에서는 정밀 토지피복도를 이용하여 DCIA를 산정하였으며, 이를 이용하여 유출량 해석을 수행한 결과 전체 불투수지역 자료를 사용한 것 보다 높은 정확도를 보였다. 또한 대상유역의 녹색 사회기반시설 설치에 따른 유출량의 변화를 평가하기 위하여 DCIA와 폭함수를 이용한 분석을 수행하였다. 분석결과 녹색 사회기반시설 설치에 따른 DCIA의 감소율에 따라 첨두홍수량 저감을 확인할 수 있었다. 이러한 결과는 도시유역의 홍수량 저감방안으로서 DCIA 분석을 기반으로 한 녹색 사회기반시설을 보다 적극적으로 도입할 수 있다는 것을 의미한다.
