In South Korea since 1970s the rapid development of economic growth has brought about "Urbanization" in many areas and also raised the level of people's life in many ways. At the same time, however, the industrialization and overpopulated districts in many areas have caused the problems of air pollution in necessary. Among those air pollution, in particular, in large cities has become more serious since 1990s than before. Air pollution, like TSP and SO$_{x}$ caused by heating, generation of electric power and industrialization in 1980s, showed as that of the type of an underdeveloping country and was not hazardous enough to people in the least. Unfortunately, in 1990s NO$_{x}$, CO and O$_{3}$ caused by the soaring numbers of many types of cars have exhausted air pollutant more hazardous as the same air pollution type of many developed countries. So, the purpose of this study would be to analyze the changes of concentration of NO$_{x}$ and CO on environmental air by traffic volume and from the side drive way to the degree of distance in Sungnam City, and recognize the citizens' consciousness to air pollution and suggest the best walking point in part, and plan to design the reasonable use of cars and finally make the air quality improve toward the better-ment in part. From the research result we can know that people walking in the street would be protected from the hazardous air pollutant caused by the cats if they walk apart from a drive way as far as they can in the street. Accordingly, it might, to minimize th affect of air pollution, be thought to be desirable that the consideration of in introduction the system that the vehicle using the diesel engine motor should use the centered-lane aparted from road. Another to be desirable is that along side the road, the trees inhaled the pollution should be planted.

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.

The purpose of this study, the trend of renewable energy, domestic and foreign renewable energy policies, and the flow of the legal system related to renewable energy location were identified, and a location analysis using public data was studied when solar energy was located. First, renewable energy is leading to energy conversion by reducing the proportion of existing fossil fuel-centered energy sources in the global trend and increasing the proportion of renewable energy, an eco-friendly energy source, and changing the institutional and market structure. Second, large-scale solar energy power plants are installed and operated in rural areas where there is no change in insolation and land prices are cheaper than in urban areas where there are many changes in insolation due to surrounding high-rise buildings and street trees. Third, if a preliminary location review is conducted using public data at this time, it will be easy to identify the optimal location for area and size calculation. Fourth, the solar energy location functional area was studied in area A, and the total area of the target area was 624.5km², with 392.7km² and 62.9% of the avoidance area where solar power cannot be located.

This study developed a new methodology to evaluate the carbon storage using a Mobile Mapping System according to the life cycle of street trees. The system for calculating the carbon storage of a roadside tree using the MMS developed in this study consisted of a database, memory, processor, user interface, and communication module. The carbon storage was calculated for 261 trees in the Cheonan-Asan New Town (distance: 2.1 km, area: $283,698m^2$). The average biomass and carbon storage of Metasequoia glyptostroboides were highest at 34.5 kg and 17.3 kg C and Chionanthus retusa were lowest at 19.5 kg and 9.8 kg C, respectively. The total biomass and total carbon storage of Ginkgo biloba were highest at 5028.8 kg and 17.3 kg C and Chionanthus retusa were lowest at 780.7 kg and 390.3 kg C, respectively. Based on the roadside tree database, the amount of carbon storage in a given area was converted to Google format and visualized in 3D by GIS analysis.

Recently, a study is conducting to image collection and auto detection of attribute information using mobile mapping system. The road sign attribute information detection is difficult because of various size and placement, interference of other facilities like trees. In this study, a text detection method that does not rely on a Korean character template is required to successfully detect the target text when a variety of differently sized texts are present near the target texts. To overcome this, the method of incremental right-to-left blob projection (IRBP) was suggested as a solution; the potential and improvement of the method was also assessed. To assess the performance improvement of the IRBP that was developed, the IRBP method was compared to the existing method that uses Korean templates through the 60 videos of street signs that were used. It was verified that text detection can be improved with the IRBP method.

'Sukchunjeahdo' illustration-book, which was left by Han, Pil-gyo(韓弼敎 : 1807~1878)in the late Joseon Dynasty, includes pictorial record paintings containing government offices, Eupchi, and Feng Shui condition drawn by Gyehwa(界畵) method Sabangjeondomyobeop(四方顚倒描法) and is the rare historical material that help to understand spatial structure and landscape characteristics. Youngyuhyun(永柔縣) and Sincheongun(信川郡) town, the case sites of this study, show Feng Shui foundation structure and placement rules of government offices in the Joseon Period are applied such as 3Dan 1Myo(三壇一廟 : Sajikdan, Yeodan, Seonghwangdan, Hyanggyo), 3Mun 3Jo(三門三朝 : Oeah, Dongheon, Naeah) and Jeonjohuchim(前朝後寢) etc. by setting the upper and lower hierarchy of the north south central axis. The circulation system is the pattern that roads are segmented around the marketplace of the entrance of the town and the structure is that heading to the north along the internal way leads to the government office and going out to the main street leads to the major city. Baesanimsu(背山臨水 : Mountain in backward and water in front) foundation, back hill pine forest, intentionally created low mountains and town forest etc. showed landscape aesthetics well suited for the environmental comfort condition such as microclimate control, natural disaster prevention, psychological stability reflecting color constancy principle etc. and tower pavilions were built throughout the scenic spot, reflecting life philosophy and thoughts of contemporaries such as physical and mental discipline, satisfied at the reality of poverty, returning to nature etc. For government office landscape, shielding and buffer planting, landscape planting etc. were considered around Gaeksa(客舍), Dongheon(東軒), Naeah(內衙) backyard and deciduous tree s and flowering trees were cultivated as main species and in case of Gaeksa, tiled pavilions and pavilions topped with poke weed in tetragonal pond were introduced to Dongheon and Naeah and separate pavilions were built for the purpose of physical and mental discipline and military training such as archery. Back hill pine tree forest formed back landscape and zelkova, pear trees, willow trees, old pine trees, lotus, flowering trees etc. were cultivated as gardening trees and Feng-Shui forest with willow trees as its main species was created for landscape and practical purposes. On the other hand, various cultural landscape elements etc. were introduced such as pavilions, pond serving as fire protection water(square and circle), stone pagoda and stone Buddha, fountains and wells, monument houses, flagpoles etc. In case of Sincheongun town forest(邑藪), Manhagwan(挽河觀), Moonmujeong(文武井), Sangjangdae(上場岱) and Hajangdae(下場岱) Market place, Josanshup<(造山藪 : Dongseojanglim(東西長林)>, Namcheon(南川) etc. were combined and community cultural park with the nature of modern urban park was operated. In this context, government office landscape shows the garden management aspect where square pond and pavilions, flowering trees are harmonized around side pavilion and backyard. Also, environmental design technique not biased to aesthetics and ideological moral philosophy and comprehensively considering functionality (shielding and fire prevention, microclimate control, etc.) and environmental soundness etc. is working.
