1980년대 후기부터 교통정책의 우선 목표는 지역경제성장 자체가 교통문제를 스스로 해결할 수 있도록 하기 위하여 종래의 관리 중시의 정책은 다시 토지이용 정책으로 변화를 초래하엿다. 오늘날 대도시는 개개 졍제활동 주체들의 동적인 경제 행태에근거하여 분산구조를 띠고 있다. 이러한 동적인 경제행태에 미치는 요소들은 교통체계와 토지이용과 상호연관성의 연구에 필수적인 지가, 인구분포, 통행행태등이다. 그러나 전통적인 단핵도시 모형은 대도시의 분산구조형태의 동적인 과정을 설명하는데는 한계가 있다. 본 연구는 대도시의 변천과정을-도심 및 부심의 출현·소멸현상-설명함으로써 도시교통정책 필수적인 입지와 통행패턴에 대한 새로운 동태적 이론의 기초를 제공하는데 그 목적이 있다. 이를 위하여 지역경제 성장과 도시공간구조와의 동태적관계를 통합하는 토지이용과 교통의 연속 모형을 개발·응용하였다. 개발된 모형에서는 교통량에 따른 교통비용, 도시공간구조로 인한 외부효과들, 경제활동주체들의 비동질성, 이주비용, 그리고 집적 이익등이 매기마다 내생적으로 결정되어 대도시의 공간구조 변화를 설명한다. 경제 호라동주체들간의 ? 호물리적 교류는 소득 증대에 의하여 경제구조가 변함에 따라 새로이 결정된다. 가상적 도시와 자료를 가지고 실험한 결과 비동질적인 경제주체들의 불균형적 성장이 장기적으로 도시구조에 영향을 미치며, 기본적인 경제행위에 따라 장기동태적인 과정을 통하여나타나는 도시의 분산구조형태의 중요성을 보여주고 있다. 또한 교통비용의 변화에 따른 민감도분석을 통하여 모형의 실용성을 검정하였다.

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.

This study (1) explored spatio-temporal population distribution patterns in Jeonju by using emerging hot spot analysis and (2) identified the influential factors to determine the spatio-temporal patterns by using multinomial logit model. The major findings are as follows. First, the results of emerging hot spot analysis indicated that the 100*100m grid in the urban area of Jeonju was found to have a category of hot spots, whereas most of the cold spot series was concentrated in the outskirts of the city. Also, new towns such as Jeonju Eco City, Jeonbuk Innovation City, and Hyocheon District were persistent or intensifying hot spots, Third, the results of multinomial logit model revealed that the factors influencing deterrmining the spatio-temporal patterns were accessibility to schools, hospitals, parks, and walfare services. This study offered a deeper understanding of urbanization and regional changes in Jeonju, and important information for urban planning.

This paper has analyzed Seoul metropolitan area on the basis of cluster characteristics and it is to understand the traits of each clusters. In order to modelize the area, 10 different indicators were selected among components of a city such as population, activities, land and facilities. Also through principal component analysis, similar characteristics or congenialities of the variables were derived as a common factor. The result was organized by factor score from hierarchical clustering method and as a final result, metropolitan area was clustered into five areas.

In recent years, fast growing cities in Korea are showing signs of being vulnerable to more disasters as their population and facilities increase and intensify. In particular, fire is one of the most common disasters in Korea's cities, along with traffic accidents. Therefore, in this study, we analyze what type of factors affect the fire that threatens urban people. Fire data were acquired for 10 years, from 2007 to 2017, in Jinju, Korea. Spatial distribution pattern of fire occurrence in Jinju was assessed through the spatial autocorrelation analysis. First, spatial autocorrelation analysis was carried out to grasp the spatial distribution pattern of fire occurrence in Jinju city. In addition, correlation and multiple regression analysis were used to confirm spatial dependency and abnormality among factors. Based on this, OLS (Ordinary Least Square) regression analysis was performed using space weighting considering fire location and spatial location of each facility. As a result, First, LISA (Local Indicator of Spatial Association) analysis of the occurrence of fire in Jinju shows that the most central commercial area are fire department, industrial area, and residential area. Second, the OLS regression model was analyzed by applying spatial weighting, focusing on the most derived factors of multiple regression analysis, by integrating population and social variables and physical variables. As a result, the second kind of neighborhood living facility showed the highest correlation with the fire occurrence, followed by the following in the order of single house, sales facility, first type of neighborhood living facility, and number of households. The results of this study are expected to be useful for analyzing the fire occurrence factors of each facility in urban areas and establishing fire safety measures.

This paper offers a method to measure the distribution of niches of two types of social organizations. Internet sites and voluntary organizations. based on the socio-demographic characteristics of their members. It examines the niches of Internet sites based on age and education of site visitors and those of voluntary organizations based on age. education. and occupational prestige of their members. The method to measure organizational niches makes it possible not only to understand the niche width of organizations but also to examine the extent to which organizations .potentially compete and coexist. This leads to a method to recognize the way organizational environments influence the performance of individual organizations ecologically. To conclude, this paper shows that organizations are socially embedded through a process of pariticipation in which individual members choose their organizations not randomly. but based on their socIoifemographiccharacteristics.

3D computer applications provide various functions such as modeling, rendering, animation, lighting and so on. Lighting is the core element in that light visualizes shape and develops characteristics of surface. In spatial design, light is the most important factor in deciding color, texture and illumination level which are the basic factors of spatial design. The purpose of this study is to define the characteristics of lighting in digital space provided by the computer, based on the fact that physical space cannot be separated from digital space, and to show how light in the physical realm relates to computer graphics technologies. This study shows there are following characteristics of light in digital space; iconic light, modifiable surface, shadowless light, 2-dimensional perception, and the particulate aspect of light but not the wave aspect of light. Light in physical or digital space is capable of producing a visual sensation. The experimental space can be realized due to the lack of physics. Further study in new illumination procedures are required as computer media expands.

This study shared with community mapping participants spatial analysis information, collected using smart devices, to give them an opportunity to objectively review their opinions. The study examined the impact of sharing such spatial information on residents' decision-making and perceptions. Yeongju-dong in Jung-gu district of Busan Metropolitan City, South Korea was selected for the case study; community mapping was carried out in Yeongju-dong to identify hazardous areas to improve pedestrian safety of primary school students. The community mapping participants drew a preliminary hazard map based on their experience and perception. Then, they drew a second hazard map after being given spatial information on pedestrian safety installations and pedestrian flow collected with smart devices including drones and sensors. Numerous changes in ranking across various sections occurred when the two maps were compared. There was a climb in the ranking of areas where the pedestrian flow was higher and lacked safety installations based on objective measurements over the perceptions of the participating people. Furthermore, according to a survey conducted among the participants, the provision of spatial analysis information using smart devices during community mapping process not only helped them recognize local community problems, but also raised their expectations that their submitted opinions would be reflected in policies. Moreover, the participants demonstrated increased self-confidence and faith in themselves as they were able to have more trust in the outcome they created.

This study aims to convey some results of a survey to professionals in the fields of territorial studies and information studies, mainly concerned with spatial implications of the informatization processes, and to draw some policy implications. Overall findings of the survey show that, along with jnformatization processes, there is high possibility of enforcing the functions and role of the metropolitan Seoul while diffusion of population and polarization reversal is quite feasible to some degree. The extension of large cities will be possible but with some limitations while urban structure will be characterized with limited functional segmentation and the emergence of multi-centers. It is prospected that there will be higher possibility of achieving regionally balanced development by informatization processes.
