  • In this study, the correlation between the heat island effect and the vegetation in Deagu Korea was performed through using Landsat TM data. the island effect, presents high temperature on air like island, is connected with correlation between the surface temperature and the temperature on the air. In this study, surface temperature was analyzed by detecting the change of urban forestry with remote sensing using the vegetation vitality statistics reference (ratio change of the Park greens in Daegu) the heat island effect not only brings the environment pollution but also brings serious problem such as the destruction of ecosystem to city as a whole. Jeff Luvall has studied to restrain the heat island effect by making urban forestry. Even though Daegu had been the serious high temperature urban area the current temperature of Daegu has been dropped. The correlation between the heat island effect and the vegetation index was analyzed by using satellite images.

  • This study used four theoretical models, such as two-point linear model, linear regression model, quadratic regression model and cubic regression model which are presented from The Ministry of Science and Technology, for extraction of urban surface temperature from Landsat TM band 6 image. Through correlation and regression analysis between result of four models and AWS(automatic weather station) observation data, this study could verify spatial distribution characteristic of urban surface temperature using GIS spatial analysis method. The result of analysis for surface temperature by landcover showed that the urban and the barren land belonged to the highest surface temperature class. And there was also -0.85 correlation in the result of correlation analysis between surface temperature and NDVI. In this result, the meteorological environmental characteristics wuld be regarded as one of the important factor in urban planning.

  • The high density of population and building; can cause catastrophe in urban areas when natural or artificial disasters break out. The aim of this paper is to assess comprehensive disasters risk of urban areas by Geospatial Information System. For this purpose, we classified disasters risk of urban areas into low categories: flood, fire, building-collapse, and shelter, and then determined factors for hazard risk assessment respectively. The results of hazard assessment can be applied to minimize the demage of disasters in establishing the urban management planning. For more systematic and professional approach the further research is need to consider more disaster assessment factors and join with related experts.

  • Urban residential area, one of the main subjects of urban and architectural studies, can be analyzed accurately and rapidly with CIS. (Geographic Information System) And the applications of GIS in urban studies are too macro to be explained in architectural terms and the ones in architectural studies are not so much active rather be used as a secondary means. So the studies in urban-architectural scale are very useful in many ways. This study explores urban-architectural possibilities of analytic capabilities of GIS through the analysis of spatial characteristics of residential area in terms of land price according to parcel attributes. It is found, firstly, that the parcel attributes have relations with land price and its distribution patterns. Secondly, it is verified that the visualization capability of GIS can be a very useful method of analysis through user-interface effects in urban-architectural scaled analysis.

  • Ever-developing information and communications technology has changed the ways of life from that of industrial society to the information-oriented community, and is widely used in a variety of social and economic contexts. Besides, urban problems in today's society are intricately involved so that the possibility of any reliable breakthrough may not to be likely. To work out these complicated problems as well as to understand the crux of the matter more comprehensively, ubiquitous urban planning has been laid out, and as a result attempts to reflect this system are cautiously made in metropolitan areas. However, most u-City planning, integrating uibiquitous technology, has focused on creating urban infrastructure and its services, therefore neglecting the importance of housing in urban space. Consequently, thorough u-City planning has yet to be defined in relation with urban space, and housing planning, established on the basis of the user-oriented housing environment, needs to be urgently made. Centering on the importance of housing in the construction of an improved future urban environment, this study aims to discuss the role of urban environment planning where metropolutan residents can enjoy a comfortable and convenient life. As well, this research paper seeks to focus attention on the consideration for users that is often disregarded but requires reflecting in the u-City planning.

  • The purpose of this study was to compare the health services information need between urban area and rural area in Sooncheon City. For accomplishing this purpose, we selected 1,060 adults randomly, 744 urban residents and 314 rural residents were surveyed from 1st, December to 31st, December in 1999. Compared the difference between two areas by cross tabulation, and chi-square test were used. The results of this study are as follows: 1. There were statistically difference in sociodemographic characteristics between urban residents and rural residents, such as age, education, job, income, and insurance payment(p<0.001). 2. According to the health utilization behavior, types of health facility, satisfaction of medical cost, and satisfaction of medical results were statistically different between the two areas(p<0.001). Also utilization of the health service center, and accessibility were statistically different between urban and rural areas(p<0.001). 3. Experiencing the health service information, type of health service information, methods of information, effectiveness, and satisfaction were statistically different between the two areas(p<0.001). 4. And experience of using computer, and internet and preference of method of health service information were statistically different between urban and rural areas. Therefore, the construction of health information system should be carefully reviewed by community health service centers and they should consider the different residents information needs, and accessibility and convenience of community residents.

  • This paper proposes a method to segment urban scenes semantically based on location prior information. Since major scene elements in urban environments such as roads, buildings, and vehicles are often located at specific locations, using the location prior information of these elements can improve the segmentation performance. The location priors are defined in special 2D coordinates, referred to as road-normal coordinates, which are perpendicular to the orientation of the road. With the help of depth information to each element, all the possible pixels in the image are projected into these coordinates and the learned prior information is applied to those pixels. The proposed location prior can be modeled by defining a unary potential of a conditional random field (CRF) as a sum of two sub-potentials: an appearance feature-based potential and a location potential. The proposed method was validated using publicly available KITTI dataset, which has urban images and corresponding 3D depth measurements.

  • 최근 GIS와 위치정보를 실시간으로 서비스하는 GPS(Global Positioning System)를 통합함으로써 지표의 지형지물 및 현상과 실시간 물체의 이동상황 등의 위치정보 파악이 가능하게 되었다. 그러나 GPS에 의한 실시간 물체의 이동상황 및 위치정보는 데이터를 수신 받는 시스템에서만 구현되는 단점이 있어 원거리에 있는 업무관리자에게 신속한 정보전달의 어려움과 업무의 효율성등 여러 가지 상황을 능동적으로 대처하는데 한계가 있다. 본 연구에서는 최근 정보통신 기술의 발달로 지리적으로 분산되어 있는 컴퓨터가 서로 정보를 공유할 수 있도록 네트워크 화되는 정보통신 기술을 기반으로 GIS와 GPS, 무선통신시스템과 네트워크를 통합함으로써 원거리에 있는 업무관리자에게 실시간으로 물체의 이동상황 및 위치정보의 파악이 가능한 통신시스템의 설계와 정보전달을 신속하고 원활하게 수행할 수 있는 통합정보 구현시스템을 개발하는데 목적이 있다.
