This study attempts to investigate the spatial characteristics of medical hospital distributions in Korea. For the purpose we examine the inter- and intra regional variations in the distributions of clinics by specialty subject. In particular, we analyze the distribution patterns of Location Quotients of clinics for 12 specialty subjects in Seoul. Medical services tend to be concentrated on the large cities, especially in the Metropolitan Seoul Area. In particular, clinics and medical doctors as well as large scale general hospitals have been strongly concentrated on the Metropolitan Seoul area. These circumstace may be related with the fact that medical hospitals are established and operated by private sector in Korea, and thus they attempt to find their location where they can get maximum profit. The distribution patterns of clinics of 12 specialty subjects can be classified to several characteristic patterns. In particular, clinics of plastic surgeon tend to be strongly concentrated on the Gangnam area in Seoul. Finally, clinics of plastic surgeon tend to be located on the areas near the subway stations along the subway Line 2 and Line 3 in the beginning. The existence of plastic surgeons turns out to have significant role on determining the location for the newly opening plastic surgeons in the later. Therefore, their agglomeration has been getting more strongly.

Facility location problem is an important subject in many areas of modern business environment. In this paper, we deal with uncapacitated and multi-period facility location problem where the object is a maximization of total profit within predetermined cost. We assume that all demand have to be met. Particularly, we represent various types of customer based on four well-known urban spatial structures to represent a spread of customers. Those are concentric zone model, sector model, multiple nuclei model and star model respectively. We apply to the genetic algorithm to simulate a large scaled problem and develop simulator. We analyze both optimal numbers and locations of facilities for each urban structure. Furthermore, we examine the appropriate time to further expansion of the facilities in the planning horizon. The experimental results show that the developed algorithm can be applied effectively to the facility location problem in the various types of urban area.

Recently, with the demand for airservice increasing and localization accelerating, airport construction is booming. However, in the case of an unsuitable airport site selection, it might cause a reduction in airport service and a decrease in airport demand. Thus, it is necessary to construct a representative airport and choose a suitable site selection method for economical and efficient airports in order to make the utmost use of airport functions. In this study, GSIS was used to select the airport site and applied to case study areas. GSIS could present a new method for efficient and scientific analysis in airport site selection including various factors over an extensive area. The use of both, the paired comparison method and the delphi method, could improve the objectivity of analysis results in the process considering the relative weight grade of data and priority order of analysis factors, used in airport site selection.

This study examines the spatial diffusion and locational charateristics of convenience stores in Daegu which had increased rapidly in the 1990s. The first convenience store (CVS) was introduced in the zone of transition of (Namgu district) adjacent to the city center or CBD in 1992. Thereafter they diffused into CBD and residential areas, but they have centered around places where their steady purchasing population was distributed. As a result, the spatial distribution of CVSs in Daegu shows a very uneven pattern concentrated in areas with many high school, in commercial and business areas, and apartment residential areas. It seems that this pattern is derived from two basic locational factors. Primarily, the location of CVSs in Daegu is very closely related with the spatial distribution of the demand population which will be clients for CVSs. Secondarily, it is also affected by the accessibility of streets which the demand population utilizes easily.

This study is to examine the remained basis and the locational characteristics of manufacturing in Chonnam region. First, the locational characteristics of manufacturing in the peripheral region examined through theoretical discussions about manufacturing location. And the locational characteristics of the small and medium firms and large firms be studied as to understand the precedent characteristics of Chonnam region. Chonnam region have the precedent characteristics that the regional capital is not accumulated as Japen exploit agricultural products at a colonial period. And SOC, industry and technology are not developed as geographically Chonnam lesion turn aside the economics axis of Korea-Japen-America within a period of industrialization. Manufacturing firms have beer make up the traditional indigenous firms which base on local market, agriculture and marine products in Chonnam lesion. The characteristics of these firms mainly are food & drink, nonmetal industry that is composed of the small and medium sized firms. The industrial structure is changing to machinery, chemistry, electronics industry from food & drink, nonmetal industry. But these industry is making the simple products. In Chonnam region, these change of industrial structure was expanding to the inland or coast region from the neighhoring region of Kwangju metropolitan. The blanch factories of large enterprises that located in Chonnam region are not connected with small and medium sized firms. The small and medium sized firms are not developed. Because these large enterprises are the iron and steel industry or chemistry industry. So the large-manufacturing firms have characteristics of the capital intensive industry, and make up the monopolistic industrial space of fordist blanch factories.

Public library accessibility directly affects library usage, and the disproportionate distribution of accessibility is a decisive factor limiting the equitable provision of library services. In this regard, this study analyzed the spatial accessibility of public libraries in Busan and identified the factors affecting accessibility of public libraries using spatial regression analysis. As a results of the analysis, the accessibility of public libraries in the Busan showed large deviations by region. Also, spatial distribution of public libraries had no correlation with the settled population and use of public transportation, and location of public libraries was inefficient, in terms of social equity. The results of this study will assist to understand the spatial accessibility of public libraries in Busan, to identify factors that affect the accessibility. Moreover, this study is expected to be utilized as fundamental data for releasing disparities of the spatial accessibility and selecting new location of public library in Busan.

The purpose of this research is to measure a gravitational attraction about urban pulbic service facilities and to evaluate the location of public service facilities. It is important in that these facilities should provide more inexpensive and convenience public service to users. To do this, the GIS's spatial analysis and gravity model were used to analyze the efficiency of the public facilities. The gravity model was conducted as the main analysis method, and another model for this analysis was the discrete model. The gravity model is originally to anticipate migration flows, traffic flows and other types of movements so that this model compares the gravitational attraction between places. The discrete model is to find the optimal location and to evaluate a location of facility regarding urban areas as the combination of node and link. In this research, these two models were adopted to compare and analyze location of Mapo-Gu Office. The results of this research indicated that the locational evaluation of urban public service facilities discovered the appropriateness of those facilities, and the public facilities was necessary to displace to other site.
