The objective of this study is to introduce the urban utility concept that combines urban growth and urban disasters in the aspect of a conceptual theory. While many studies focused on the dollar amount damaged from a disaster, it requires adding not just building damages or human body losses but also the quality of life satisfaction. An issue in measuring the quality of life satisfaction needs to introduce a proper mode quantifying it. This study introduces the urban utility change in measuring the negative impacts of a disaster on urban life, which has been rarely investigated. To identify urban utility, urban flooding that is a cross-sectoral agenda and important to both developed and developing countries was adopted to respond to its increased frequency and damages, encouraging governments to focus on flood control policies. By combining a literature review on urban utility and urban growth, this study defined the urban utility concept as a net benefit of a resident with earnings subtracting housing and commuting costs. The theoretical study also explained that urban utility and its components dynamically change as per urban growth and disasters that even reversely affect urban growth. Because the urban utility can be one of the useful indices to appreciate the relationship between a disaster and urban growth, it is highly expected to apply for similar disaster impacts on urban areas, including COVID-19 and various global warming issues.

The research on urban forests in Chuncheon, so far, has mainly conducted in Ponguisan urban forest. Research on other urban forests in Chuncheon was scarce. Accordingly, in this study, the author chose the main urban forests in Chuncheon and tried to find a way of efficient establishment and management of urban forests in Chuncheon by field and questionnaire survey. The research findings, there were several reasons why effective management can not be implemented in the main urban forests in Chuncheon. To solve these problems and make an efficient establishment and management of urban forests in Chuncheon, the first way is to make forest management plans on the urban forest in Chuncheon and expand administrative organization, personnel and budget. Establishment and management of urban forests needs a practical, strengthened overall management system. The second way is to enhance the regional and functional characteristics for urban forest, expand the area of urban forests, and enhance management of Street trees. The third way is to designate Urban Nature Park or Urban Park for the main urban forests in Chuncheon and need to change the ownership of the urban forests by purchasing. The fourth way is to respond to Chuncheon citizen's preference and their way of utilization when create the urban forests in Chuncheon, expand convenience facilities, relaxation facilities as well.

This study investigates the impacts of urban land-use fraction and temperature advection on the urban heat island intensity over the Seoul metropolitan area using the UM (Unified Model) with the MORUSES (Met Office Reading Urban Surface Exchange Scheme) during the heat wave over the region from 2 to 8, August 2016. Two simulations are performed with two different land-use type, the urban (urban simulation) and the urban surfaces replaced with grass (rural simulation), in order to calculate the urban heat island intensity defined as the 1.5-m temperature difference between the urban and the rural simulations. The land-use type for the urban simulation is obtained from Korea Ministry of Environment (2007) land-use data after it is converted into the types used in the UM. It is found that the urban heat island intensity over high urban-fraction regions in the metropolitan area is as large as 1℃ in daytime and 3.2℃ in nighttime, i.e., the effects of urban heat island is much larger for night than day. It is also found that the magnitude of urban heat island intensity increases linearly with urban land-use fraction. Spatially, the estimated the urban heat island intensities are systematically larger in the downwind regions of the metropolitan area than in the upwind area due to the effects of temperature advection. Results of this study indicate that urban surface fraction in the city area and temperature advection play a key role in determining the spatial distribution and magnitude of urban heat island intensity.

In the present circumstance of exploring measures for sustainable development, finding and using planning elements of historical city is getting important as a urban planning tool. Thus this study aims to examine the characters of Korean traditional urban form through three periods, Josun, modern and contemporary eras. Three urban centers representing different characteristics were selected; historical center based on 14th century's traditional planning, modern period urban center, which is related with development of railway, and contemporary urban center of late 20th century. Analyse of urban tissue, composed with form and scale of street network, blocks and plots, shows that each urban center of Seoul has certain common attributes in terms of morphology in spite of the difference of formation and development period. However this historical urban forms are rarely applicated in the current urban planning, such as new-town planning or district unit plan. This shows the necessity of modification of urban regulation for preserving the identity of our city and pursuing sustainable development.

Urban parks are progressing but are in chaos in the twenty-first century. Therefore the purposes of this study are to consider critically and classify the new paradigm of urban parks. Urban parks are one of the space products, and progressing aspects can be divided into three parts; supply, demand and market aspects. In the abstract, urban parks' progress represents process, openness or voidness, general and cultural ecology, productivity, experience program, identity or sense of place, carriers of urban regeneration, urban infrastructure, community space, multi-layered activity, active space, communication with urban space, tool of low carbon strategy and consilience. But urban parks have come under increased criticism about the long period development on trees growth, covering open space, limitation of general and cultural ecology, production, activity programs, identity and community space, visible urban regeneration, economic validity, urban sprawl, not using as the low carbon strategy, and finally negative consilience with contiguous fields. We collected these critical consideration about progressing urban parks, and proposed urban agricultural park as one of the alternative urban parks. This is closely connected with sustainable region development, low-carbon society, local food, well-being, Lohas paradigm and amenity of urban life.

As urban growth continues, the earth ecosystem is increasingly dependent on the patterns of urban growth. The impact intensity from urban growth is expected to change predictably with distance from the urban center. However we can't fully understand yet how urban development pattern affects urban ecosystem. In researches about urban ecosystem, it is important to relate the spatial pattern of urbanization to ecological processes. So we used gradient analysis with time data; 1980's, 1990's and 2000's. We attempted to quantify the urban spatiotemporal impacts in Daejeon-city and Cheonan-city, Korea, along a 75km long and 3km wide transect. Through the results, we found the impacts range of urbanization with urban development process of two cities. When the urban growth was concentrated on in both cities, the impacts intensity and range were much stronger and wider. As a result, in urban planning or green space planning, we have to consider suitable urban development forms with surrounding areas, and make legal clauses which limits landuse change. This quantifying the urban gradient is an important step in understanding urban ecology.

Population growth and rapid urbanization has been converting large amounts of rural vegetation into urbanized areas. This human induced change has increased temperature in urban areas in comparison to adjacent rural regions. Various studies regarding to urban heat island have been conducted in different disciplines in order to analyze the environmental issue. Especially, different types of thermal infrared remote sensing data are applied to urban heat island research. This article reviews research focusing on thermal infrared remote sensing for urban heat island and urban planning studies. Seven studies of analyses for the relationships between urban heat island and other dependent indicators in urban planning discipline are reviewed. Despite of different types of thermal infrared remote sensing data, units of analysis, land use and land cover, and other dependent variable, each study results in meaningful outputs which can be implemented in urban planning strategies. As the application of thermal infrared remote sensing data is critical to measure urban heat island, it is important to understand its advantages and disadvantages for better analyses of urban heat island based on this review. Despite of its limitations - spatial resolution, overpass time, and revisiting cycle, it is meaningful to conduct future research on urban heat island with thermal infrared remote sensing data as well as its application to urban planning disciplines. Based on the results from this review, future research with remotely sensed data of urban heat island and urban planning could be modified and better results and mitigation strategies could be developed.

Urban development and population have augmented the increase of impervious land-cover. This phenomenon has amplified the effects of climate change and increasing urban island effects due to increases in urban temperatures. Seoul, South Korea is one of the largest metropolitan cities in the world. While land uses in Seoul vary, land cover patterns have not changed much (under 2%) in the past 10 years, making the city a prime target for studying the effects of land cover types on the urban temperature. This research seeks to generalize the urban temperature of Seoul through a series of statistical tests using multi-temporal remote sensing data focusing on multiple scales and typologies of green space to determine its overall effectiveness in reducing the urban heat. The distribution of LST values was reduced as the size of urban forests increased. It means that changing temperature of large-scale green-spaces is less influenced because the broad distribution could be resulted in various external variables such as slope aspect, topographic height and density of planting areas, while small-scale urban forests are more affected from that. The large-scale green spaces contributed significantly to lowering urban temperature by showing a similar mean LST value. Both of concentration and dispersal of urban forests affected the reduction of urban temperature. Therefore, the findings of this research support that creating urban forests in an urban region could reduce urban temperature regardless of the scale.

21C는 문화 예술의 시대가 될 것임을 예고하고 있다. 따라서 전통적으로 지역을 연구해 온 지리학은 지역 문화에 대한 심층적 연구를 필요로 하게 되었다. 지역 문화를 밝힐 수 있는 중요한 것 중의 하나가 지역의 상징이다. 오늘날 지구 도시의 출현과 더불어 특히 도시 문화에 대한 연구는 시대적 요청이 되고 있다. 도시 문화를 도시의 상징 즉 한국 각 도시가 제정하고 있는 상징 노래(시가(市歌)), 상징새(시조(市鳥)), 상짐꽃(시화(市花)), 상징 나무(시목(市木))를 통해 분석하여 도시 상징의 공간 환경을 밝혀 보고자 한다. 한국 도시의 상징 노래를 분석해 보면 노래가사 속에는 공간 환경 요소를 포함하고 있는데, 그 중 지형 주로 산과 강의 명칭 그리고 해당 지역의 지명은 거의 모든 노래 가사 속에서 나타나고 있다. 이러한 공간 환경 요소들은 특정 도시의 정체성을 나타내 주며, 그 시민들의 통합성과 일체감을 불러일으키는 상징적 공간으로 볼 수 있다. 특히, 산 및 강과 관련된 지명은 국토의 70%가 산지지형인 우리나라에서는 풍수의 기본 요소로서 산 및 물과 관련된 상징적 공간으로 볼 수 있다. 지명 또한 그 지역의 이미지를 잘 나타내는 상징적 공간이 핀다. 한국 도시의 상징물 즉 상징새, 상징 나무, 상징꽃 분석을 통해 한국 도시의 상징물은 중복 제정이 많다. 특히 상위 계층의 상징물이 하위 계층에서 중복 제정되었다는 점이다. 이러한 상징물들은 우리 민족의 삶을 통해 내려온 상징의 공간 환경으로 볼 수 있으나, 해당 도시의 기후, 토양 등 공간 환경적 특성과 상관없이 중복 제정된 점과 정체성이 없는 외래종이 많은 점은 시대적으로 상징물을 재검토해야 할 필요성이 있다. 가장 지방적인 것이 가장 지구적인 것이 되어야 할 시대에 우리의 기후, 토양, 문화적 특성에 맞는 도시의 상징물을 정할 것이 요망된다.
