  • This purpose of this work is to explore the characteristics of urban thermal environment distribution with the case of Daejeon. To do that, this work applied GIS Spatial Statistics to the LandSAT images gathered from 2000 to 2011. The urban thermal environment distribution at the time point of 2 showed high spatial autocorrelation. Therefore, it is judged that spatial autocorrelation is needed to increase the reliability and explanatory power of the characteristics of thermal environment distribution. In the case of the thermal in Daejeon, its positive clustering appeared high at the time point of 2, and its clustering in 2011 more gradually decreased than that in 2000 to 2011. In particular, given the decrease in the core H-H region, it was found that the thermal environment of Daejeon was greatly improved. However, since the rise in the region L-L means another changed like construction of a new city, it is judged that it is necessary to come up with a proper plan. It is considered that this analysis of the characteristics of urban thermal environment distribution in consideration of spatial autocorrelation L-L be useful for providing a fundamental material necessary for the policy and project of thermal environment improvement.

  • Now architecture has been become a significant element which is able to determine the competitiveness as a cultural product by going beyond the concept that architecture offer a space for just residence and office. From old times, planning and managing the urban space create living space to be more comfortable and efficient. Nevertheless, all of a public and private have resolved urban problems only to create economy growth by shortsighted approach. Therefore, a more macroscopic for composing an urban environment emerged the need for access in terms of the plan, to these aspects of the landscape and urban residential environment that can be applied to the United States's PUD techniques and focus on the development of urban space cases by applied PUD to improve a more rational and efficient urban space and to creation lively dwelling environment and the favorable landscapes forming want to try.

  • The purpose of this study is to identify the relationship between the physical environment and mental health of the adolescents in urban and rural areas. This study was performed using the questionnaire survey method. The research subjects were high school students in Seoul and Jeollabuk-do rural areas. The questionnaire inquired about the housing, neighborhood, and school environments, and these contents were depended on previous studies. The survey was conducted from August 27 to September 6, 2013, and 446 data were collected. They were analyzed with the SPSS 12.0 program. The main results are as follows. 1) The urban adolescents evaluated physical environment to be better than rural adolescents. Specifically, the urban adolescents evaluated 'facility/accommodation', 'security/health', 'amenity' of the housing environment, 'disorder', 'comfortability', 'nature awareness' of the neighborhood environment, and 'noise', 'overcrowding', and 'security' of the school environment to be higher. 2) The urban adolescents' self-esteem was significantly higher than rural ones. 3) The physical environment factors, which had effects on adolescents' mental health, are different depending on the areas, and so adolescents' physical environment would be designed by the local environment conditions.

  • The objective of this research is to study the method to produce biotope map by using GIS. Surveying and analyzing the situation of biotope map in the country, it was found that biotope map should be produced to be utilized in establishing urban plan and environment preservation plan. Considering the history of materials, preparation method and type of use, the types of original materials can be classified into 3 types, namely, data based on configuration map, the existing thematic map and materials of surveying natural ecology. Biotope map is composed of configuration thematic map that shows the shape and position of surface, urban thematic map that is the standard of unit biotope shape and urban ecology map that shows the urban ecologic situation. Extracted and processed from the original material, each thematic map is produced as biotope map that shows the type of biotope. It is expected that biotope map can be utilized in the area of urban plan including establishment of basic urban plan and urban management plan as well as environment planning area including evaluation of environment influence, establishment of environment preservation plan, consolidated environment management for natural environment and life environment.

  • Today's cities require deeper understanding of the thermal environment and PM10 as their management becomes more critical. Based on these circumstances, this study investigated the Granger causality between the thermal environment and PM10 of the 25 districts of Seoul, the most populous and urbanized city in Korea. The results of the Granger causality test on the thermal environment and PM10 were classified into 12 types. Except for type 12, the temperature and urban island heat intensity of the other 11 types operated as a Granger-cause to each other in both directions. Temperature operates as a Granger-cause of urban island heat intensity in type 12. The PM10 level and urban pollution island intensity operated as a Granger-cause to each other in all districts. For types 1 and 2, thermal environment operated as a Granger-cause to PM10 in one direction, and type 3-type 12 confirmed that thermal environment and PM10 operated as a Granger-cause in both directions. Findings reveal the intricate causalities between thermal environment and PM10 at the district level and suggest mitigation strategies that are more location based.

  • The urban ecosystem, unlike the natural ecosystem, has been affected by the urban environment, so the existences of normal creatures have been threatened and eventually the stability has declined to consist of those that have adapted to such. Therefore, by creating a list of such organisms, their number of variety can be found out and their ecological distinction can be understood. Because flora is known to be an ecological index reflecting region's effects of human and societal environments, weather, and climates, it is a useful method of finding out the ecological position and distinctiveness of that region. The study site is part of watershed at Yangjae Stream, Kahngnam-ku, Seoul. In this study, the difference of flora in each land use type are investigated by plant identification. The purpose of this study is to evaluate the city's plant surviving environment, and eventually to contribute to the restoration of urban green spaces by finding out the plants which are appropriate for the corresponding environment. After doing the study, it was found that the urban forest is the most stable urban ecosystem while the urban park is seriously disturbed, and ecologically unstable. The urban stream is also disturbed continuously.

  • Air pollution has attracted ever-increasing attention because of its substantial influence on air quality and human health. To better understand the characteristics of long-range transported pollution, the single particle chemical composition and size were investigated by the single particle aerosol mass spectrometry in Fuzhou, China from 17th to 22nd January, 2016. The results showed that the haze was mainly caused by the transport of cold air mass under higher wind speed (10 m·s-1) from the Yangtze River Delta region to Fuzhou. The number concentration elevated from 1,000 to 4,500 #·h-1, and the composition of mobile source and secondary aerosol increased from 24.3% to 30.9% and from 16.0% to 22.5%, respectively. Then, the haze was eliminated by the clean air mass from the sea as indicated by a sharp decrease of particle number concentration from 4,500 to 1,000 #·h-1. The composition of secondary aerosol and mobile sources decreased from 29.3% to 23.5% and from 30.9% to 23.1%, respectively. The particles with the size ranging from 0.5 to 1.5 ㎛ were mainly in the accumulation mode. The stationary source, mobile source, and secondary aerosol contributed to over 70% of the potential sources. These results will help to understand the physical and chemical characteristics of long- range transported pollutants.
