  • In order to improve the urban thermal environment, efforts are being made to increase green areas in cities that include park construction, planting, and green roofing. Among these efforts, urban parks play an important role not only in improving the urban thermal environment, but also in terms of ecosystem services (serving as resting places for citizens, providing cleaner air quality, reducing noise, etc.). Therefore, the purpose of this study is to suggest planning and management guidelines for urban parks that are effective in improving the thermal environment, by analyzing the urban surface temperature reduction performance of urban parks. To do this, first, land surface temperature was calculated by using Landsat 8 images. Second, the PCI (Park Cool Island) index was calculated to identify the temperature reduction performance of urban parks. Third, the characteristics of parks (area, shape, vegetation) and the surrounding spatial characteristics (land cover, building-related variables, etc.) were identified. Finally, the relationship between the PCI indices (PCI scale, PCI effect, PCI intensity) and the characteristics of the parks and their surroundings were analyzed. The results revealed that the parks consisting of a larger area, simple shape, and higher tree coverage ratio had increased PCI performance, and were advantageous for improving the urban thermal environment. Meanwhile, PCI performance was found to have decreased in areas with a higher impermeable area ratio and building coverage ratio. The outcomes of this study can be used to identify priority areas for planning and management of urban parks and can also be utilized as planning and management guidelines for improving urban thermal environment.

  • This study aims to investigate the change in building density and residential environment after the reconstruction of decrepit public rental housing complexes formed in accordance with the Land Readjustment Project during the 1970s-80s. The results of this study can be summarized as follows: First, in terms of change in residential environment after the reconstruction, floor plans that were limited to two to four types and to small apartments measuring $42.9m^2$(13py)-$56.1m^2$ (17py) became varied, presenting 5-6 types of floor plans and various sizes of apartments. In particular, the reconstructed apartments were mainly built in a size smaller than 85($m^2$) and in the 3LDK floor plan and staircase-style unit architectural structure in order to reflect the lifestyle of residents. Second, in terms of change in building density after the reconstruction, the building coverage ratio did not change a lot, but the floor area ratio showed great change depending on the complex, ranging from a minimum of 2.9 times (Singdong Complex) to a maximum of 5.4 times (Eoyangdong Complex). Such change is attributable to the reconstruction policy that aims to improve the residential environment for original residents, secure economic feasibility and efficiency, and reflect the lifestyle of residents while incorporating dividends assigned to the existing housing project members as well as the maximum floor area ratio allowed by the regulation. Additionally, in terms of change in the number of floors and building density after the reconstruction, the former 5-story apartments were changed to apartments with 16-28 stories. Accordingly, the number of households in each complex has also increased by 20%. Third, according to the characteristics of parking facilities in terms of the size and density of parking spaces, former apartment complexes had only aboveground parking lots, not underground parking area. The newly constructed apartment complexes have underground parking space, and the parking-housing ratio is 1.1-1.3 cars.

  • The functions and uses of existing buildings are not properly changing as modern life needs. As a result, the frequent reconstruction(construction after removal) of existing buildings have been done but it became more and more difficult because of strengthening of regulations and systems concerning construction. And also it has several disadvantages like lower plot ratio and site coverage than existed buildings, enormous construction cost, production of waste-construction materials and thoughtless consumption of natural resources, which gives rise to environmental pollution. Therefore renovation is brought to the fore. In Korea, many business buildings were constructed in 1960s-1970s, during the period of high growth. Such buildings needs to be repaired in whole. It is caused by the change of social, economic, and cultural conditions and deterioration of equipments. Therefore renovation meets some necessary conditions; recovery of building functions and extension of building life span. In case study, the present state of renovation in business buildings is 1) Basic safety, for example, fire prevention and crime prevention, is great important. 2) Advanced technology, INS(international news service), IBS(Intelligent Building System), and internationalization, is pursued for adapting to multimedia ages. 3) It tries to promote proficiency, and to save the energy using spatial environment and natural energy(light and sound). Also, improving comfortable level of users and installing equipments for physically handicapped person needs to be considered.

  • 민간자본으로 도시공원을 조성하기 위한 특례제도가 도입된 이후, 보다 매력적인 인센티브를 부여하기 위하여 법률 개정이 이루어졌다. 본 논문에서는 민간공원의 취지에는 적극 찬성하지만 공익성을 강조해야 하는 공원에서 과연 적절한 조치가 이루어지고 있는지에 대한 의문을 바탕으로, 민간공원의 정책모델이었던 일본의 민설공원제도의 배경과 함께 입지, 조성, 관리의 기준이 책정된 근거와 특성을 분석하고 문제점을 고찰하였다. 민설공원은 녹지 네트워크 구축과 방재 기능에 유효하도록 입지와 공간계획이 이루어졌으며, 최소면적은 약 1.42ha였다. 공원과 같은 공간의 최소 면적인 1ha는 방재성과 실현가능성, 사회적 수용가능성을 감안한 수치였으며, 건축 부문은 제2종 중고층 주거전용지역의 기준과 지역 거버넌스와의 협의절차를 거쳐 최종적으로는 용적율 100%, 건폐율 30%, 최고높이 11층 등 허용한도의 최저 수준으로 건설되었다. 관리비는 월 300엔/$m^2$을 기준으로 35년간 소요되는 비용을 사업자가 일괄 납부하였으나 과다한 관리비가 수반되는 시설에 대해서는 시가 비용을 지출하여 민관이 함께 관리하는 형태를 취하고 있었다. 한편 입지, 허용용도, 도입시설의 한계로 매력적인 수익시설 도입이 어려우며 관리주체와 비용부담등의 문제점이 도출되었다. 우리나라 민간공원에 대해서는 도시공원 조성의 우선순위를 선정한 후 민간공원의 적정입지를 선정하고, 국민적 합의를 이룰 수 있는 수준의 입지, 조성, 관리 기준 정립 등의 개선과제를 제안하였다.

  • This study is focused on finding out the character of urban recreation forest and investigating facilities regulations of forest resources around urban areas to meet future recreation needs. The method of this study is to compare urban recreation forests with similar facilities like urban parks and natural recreation forests. By this way, this study not only identifies the characteristics of urban recreation forest as emerging recreational facility, but also outputs regulations that can be adapted to real environment. Urban recreation forest is defined as follows: It has forest with good natural landscape and easy access. It makes emotion rich and its function is focused on outdoor recreation nature education, and experiences for family group mainly within a day or on weekends. This study suggests that the minimal area of urban recreation forest should be over 100,000$m^2$, with a facility ratio less than 20%. Building coverage should be less than 7% when the urban recreation forest is under 300,000$m^2$, less than 5% when 300,000∼500,000$m^2$, and less than 3% when over 500,000$m^2$ The limits of building height is 3 stories, or under 12m. This study finds out the character, the needs of urban recreation and the criterion for project feasibility. significance of the result is supplying theoretical basement on related regulation. Based on the results, further study will establish landscape management method and legislation & application in a detailed examination.
