The purpose of this study is to analyze the effects of a comparative process so that students majoring in urban planning and design can develop the ability to present non-physical alternatives along with the ability to present alternatives to a physical environment to solve urban problems. A total of 30 students majoring in urban planning and urban design were analyzed for their satisfaction with their majors, intention to find a job related to their majors, and academic achievement. This was done after conducting a comparative course of living-lab projects utilizing idle space in a region in connection with a major education course for about a year. For the analysis, the four-group design used by Solomon was used to find the differences between students who participated in the class and those who did not. The analysis showed that the students who participated in the comparative course of the living-lab project were highly satisfied with their major and their intention to find a job related to their major. The results of this study suggest that the process of cultivating the ability to work with local residents and merchants to present physical and non-physical alternatives to solve local problems by utilizing the means of living lab projects has a positive effect on the students' attachment to their majors and their self-esteem.

Korean urban development cooperation is gradually expanding into Latin America and the Caribbean (LAC) region, but strategies to encourage domestic market players to participate are insufficient. This paper investigated the Colombian urban planning system, urban development projects, and Korean projects in Colombia, which leads to implications for international cooperation in LAC. This research, first, compares the national and regional urban planning systems of Colombian major cities, Bogotá and Medellín. Second, case studies are carried out with a land readjustment project, a Macro project for large-scale public rental housing supply, and urban development cooperation between Korea and Colombia. By doing so, the role and the directions for Korean urban development cooperation with LAC such as Colombia are discussed and proposed. The findings suggest, first, aid projects through Official Development Assistance (ODA) should establish urban networks in recipient countries. Second, it is necessary to understand the financing structure for urban development cooperation projects that are different from infrastructure projects. Third, the successful case of urban development cooperation should be demonstrated by making the development period and size optimal and manageable.

Urban areas are variously under threat including deterioration of ecological functions. Many pond wetland types have been created as part of an effort to improve and restore this urban environment. This study was arranged to examine improvement plans of wetlands in urban areas by analyzing semi-natural wetlands in farm areas. As for environment for water quality, it suggested the inflow of natural water neighboring rivers or the direct inflow of rain as the improvement plans. The result which analyzed soil pH, OM, and T-N content of the soil environment mentioned that urban areas supplied artificial sluices, removed apoptotic bodies, and used artificial soil and waterproofing materials and use of natural materials in design and construction, the sluice state of the natural form, and negligence of autumn plants were suggested as the improvement plans. Florae appeared in the subject sites of the study have found that there are 35 families 69 species in urban areas and 53 families 142 species in rural areas. As the average has found that there are 18.5 families 29.3 species in 4 urban areas and 26.3 families 53.5 species in 4 rural areas, the big difference between them was analyzed. As the cause has found that there are differences in yearly plants in farming areas when compared to urban areas, creation of various basic environments including soil and water quality was suggested to make yearly plants settle down widely. Naturalized plants have found that there are no big differences between urban areas and rural areas. However, the average of the naturalized ratio in urban areas is 17.4% as the naturalized plants are about 1/4 of the appeared plants. As it was analyzed to be higher than 7.7%, the average of the naturalized ratio in farming areas as the big difference, creation of various inhabiting environments was suggested to make more yearly plants appear like the analyzed result of the life type. Consideration of placement, materials, and inhabiting environments was suggested to make creation of wetlands well appreciated to improve functions of wetlands in urban areas. It is expected that the above results of the study will be utilized in creation and improvement of the pond wetlands which can play a huge role in increase and improvement of biological diversity in urban areas.

빈번하게 발생되는 설계빈도 이상의 국지성 호우로 도시지역의 침수피해가 매년 증가하고 있고 특히 저지대의 경우 우수의 집중 및 하수관거의 통수능 부족으로 인한 우수의 배수 불량으로 다른 지역에 비해 침수피해의 규모가 크게 나타나고 있다. 매년 반복되는 피해를 저감하기 위하여 국가 및 지자체에서는 노후관거 개량 및 통수능 확보를 위한 하수관거 신설 등 다양한 방법을 동원하고 있으나 하수관거 개량 및 신설 또는 지하저류조 설치와 같은 사업들은 많은 예산이 필요하여 지자체의 규모에 따라 예산확보가 어려울 수 있고 해당 사업을 완료하기 위한 사업기간이 오래 걸리므로 즉각적인 효과를 기대하기 어려운 실정이다. 따라서 기존 침수저감을 위한 시설을 설치하기 위한 사업에 비해 예산이 적게 소모되며, 큰 설치부지를 요구하지 않는 유출저감시설이 필요하다고 판단된다. 본 연구에서는 도로부의 노면수를 배수하기 위한 시설인 측구를 우수의 저류를 위한 저류조로 활용한 측구 저류조 개념을 이용하여 도시지역에서 침수저감을 위한 적정규모 산정을 위한 연구를 진행하였다. 빈도 30년의 강우를 적용하여 일반적인 지하저류조를 설치하였을 경우와 측구 저류조를 설치하였을 때의 침수저감효과를 비교하고 지하저류조와 비슷한 저감효과를 나타내기 위한 적정규모 산정과 측구 저류조의 배치방법을 제시하고자 한다.

In this paper, we study a sample design for survey on goodwill in retail properties to provide a protecting policy for small traders and tenants, to use basic data for a dispute case related to goodwill. Since goodwill in retail properties is occurred by individual rent company, we use the census on establishments from the Statistics Korea as population. First of all, we consider preferentially seven metropolitan cities in which there are more than half of population. Total sample size is decided as 8,000. We allocate the sample size for markets as stratum in each city using proportional formula and the sample size for industrial classifications in each market using root proportional formula. Also we compute survey weights and calculate estimators, standard errors and interval of estimators for each characteristic such as type of establishments and market in seven metropolitan cities.

This paper assessed the weights of attributes in creating transit malls. The aim of the creation was classified as travel demand management and urban revitalization. The attributes were grouped into four aspects, or 4As: attraction, amenity, accessibility, and activity. These dimensions represented land-use, urban design, transport, and socio-cultural characteristics, respectively. The analytical hierarchy process was applied to explore the weights. Accessibility(52.7%), attraction(25.6%), amenity(13.7%), and activity(8.0%) were the order of magnitude in weights for the purpose of travel demand management, while attraction(36.1%), accessibility(30.6%), amenity(17.7%), and activity(15.6%) were that of urban revitalization. The multi criteria analysis also showed different size of weights in the sub planning attributes. These results indicate that the aimin implementingtransit malls should be differentiated and highlight that the combined land-use and transport plan is essential for the successful development. Car accessibility and socio-cultural characteristics are also understood as the important factors.

근리주구개념은 도시사회구조를 이해하는 기본적 틀로서 인식되어왔을 뿐 아니라 도시공원의 계획에 따르는 공원체계의 개발 및 도시민의 여가행동 규명에 중요한 하부체계로 사용되어왔다. 80년대를 전후하여 발표된 다수의 논문에서 보고되고 있는 도시공원의 낮은 이용사례는 공원의 소극적 관리 상황 뿐 아니라 계획 그 자체에 문제가 있음을 환기시키고 있다. 본 연구는 미국의 소 도시를 대상으로 지역주민에 의한 근린주구 개념을 파악하고 주민의 근린공원 이용실태를 분석하여 전통적인 근린 공원계획의 설정목표 및 기준상의 문제를 제조명하고자 한다. 연구결과 주민의 근린주구개념의 '동질성'의 사회경제적 기능주의 입장보다는 물리지형적 특성으로 기울어 사회학자 및 공원계획가의 근린주구에 대한 기본전제에서 벗어나고 있으며, 계획가에 의해 임으로 설정된 근린공원의 서비스 영역(0.8km 둘레) 내부에 위치한 주민들의 공원비용은 주민자신에 의해 도출된 근린 주구 영역이 공원의 포함여부에 커다랗게 영향받고 있음이 밝혀졌다. 본 연구는 근린주구의 사회학적 개념과 현상학적 접근방식의 일환으로 Cognitive Mapping 기법에 대한 정리도 제시한다.
