This study aims to identify the efficiency by applying diverse index to the positions of vertex in the network among the network analysis methods in order to identify the relational location features of caves. The first consideration was about the relational location features according to the linking degree and centrality of cave. The second consideration was about the structural equivalence between caves or between caves and the surrounding tourists attractions. A variety of index examined in this study is very efficient for identifying the positions of caves in the network. Furthermore, the relational location features in consideration of surrounding tourists attractions identified the availability of more objective and quantitative expression. In particular, when there are other caves around a cave, it is also very useful to identify the structural equivalence or comparison with other caves.

The purpose of this paper is to analyse the locations and to interpret the landscapes of the local towns in Joseon Dynasty from Feng-shui's point of view. As a result of analysing the locations of towns in Gyeongsang Province, the towns which have typical Feng-shui landscapes make up to 58% of the total. Historically, the local towns that were established in the early period of the Joseon Dynasty didn't reveal Feng-shui's landscape, but those that were established in the late period of the Joseon Dynasty revealed the Feng-shui's landscape clearly. In this article, I classify the local towns of the Gyeongsang Province into 3 types: 1. Non Feng-shui type These towns are located near the seashore. The main reason that these towns were located at the seashore was defense against an enemy. 2. Semi Feng-shui type. These towns don't have natural location but have a man-made landscape, based on the principles of Feng-shui. 3. Typical Feng-shui type. These towns were typically administrational towns which were located at the center of a local region.

This study was conducted to derive the site index of forest productivity of Robinia pseudoacacia (honey plant) to characterize suitable planting sites and to investigate the effect of the site environmental factors on the site index using the quantification theory I method. The data used in the analysis were growth factors (stand age, dominant height, etc.) of the 6th national forest resources survey and various site environmental factors of a forest soil map (1:5,000). The average site index value of the R. pseudoacacia stand in Korea was 14 (range, 8 to 18). The environmental factors affecting the site index were parent rock, climatic zone, soil texture, local topography, and altitude. The accuracy of the estimation model using quantification theory I was only 33%. However, the correlation between the site index and the site environmental factors was statistically significant at the 1% level. Results of quantification analysis between site index and site environmental factors revealed that metamorphic and igneous rocks received high grades as parent rocks, climate zones received higher grades than central temperate zone, clay loam and silt loam received high grades in soil texture, and hillside received a high grade in local topography. Analysis of the partial correlation between site topographical factors and forest productivity (site index) found that soil class and altitude were partially correlated to x by 0.4129 and 0.4023, respectively, indicating that these factors are the most influential variables.

We use the properties of competitive location equilibrium to study the relationship between the demand for education and the choice of primary residential location. Consumers can work and live in a comparatively high wage place where there are few education opportunities, or live in a place where education is available and commute to work. If education and employment are each location-specific, there are pooling equilibria in which consumers locate according to their preference for education. In general, the stronger the taste for education, the greater the attraction of living close to the education site and the lower the demand for other goods, including housing. Exploring the effects of the model parameters on the spatial distribution of consumers, we find that a higher frequency of trips taken to the education site, a shorter distance between the work place and the education site, or a greater out-of-pocket education cost each leads to a wider range of consumer types selecting to reside at the education location. We also find that a higher wage lowers the range of consumers who select to live near the education site.

Location is the key theme in geography and various location theories are well established for diverse economic activities. As normative theory, the logical presentation of the location theories tends to make students appraise the class difficult and lose interests. This study presents a teaching materials and inductive method for the location of venture firms using newspaper articles as an example of the knowledge and information industry. Presented are various newspaper articles about venture firms in which the locational notions are selected to find out general location factors. And then their locational preference of large cities, diseconomies of agglomeration, the possibilities of deconcentration from large cities and new establishments in peripheral regions are presented in order. The inductive way of teaching location from specific examples to general tendencies using NIE could bring students' interests and participation which is in line with the student-oriented inquiry-based teaching emphasized recently in educational methods. It could be an effective teaching method for the location theories in economic geography and other difficult subjects.

수자원 개발에 있어 중요한 문제 중의 하나는 개발가능지의 선택과 후보지가 복수일 때 개발 우선순위를 결정하는 것이라 할 수 있다. 이러한 문제 해결을 위하여 적지분석을 실시한다. 적지분석 과정은 크게 기초 조사 및 자료수집, 예비후보지의 선정, 대안평가, 입지선정의 :t단계로 구분되는데 여기서 2-3단계인 예비후보지 선정과 대안평가 단계가 적지분석 기법이 적용되어야 할 과정이다. 기존의 의사결정 방법론들은 각 대안의 우선순위를 위해 각 항목들에 대한 가중치나 확률치를 이용한 수치적 계산에 의한 방법들이 대부분이며, 또한, 각 후보지에 대해서 동일한 항목에 대한 정보를 요구하게 되어 한 후보지이라도 정보가 없는 경우 우선순위를 위한 계산과정에서 제외하거나 결정자의 경험 등에 의한 추정 값을 사용할 수밖에 없다. 이러한 이유로 본 연구에서는 입지선정에서 대상 후보지의 인자비교를 위한 항목의 자료 유무에 관계없이 적지분석이 가능하도록 게임이론을 적용하여 수자원 개발 가능 후보지를 도출하기 위한 기본모형을 개발하였다.

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.

It is usual to prioritize the spatial variables that influence housing location by a few specialist's experienced knowledge or intuition. Multiple regression techniques were used to evaluate the spatially prioritized relationships between housing density and seasonal solar intensity parameters for a total of 134 house locations. Solar radiation and duration of sunshine on winter solstice was the most important predictor of house density located in intermontane basin. In contrast to the typical theory, elevation, slope and accessibility to road were not a dominant determining factor upon the dependent variable of house density. A clear verification has been made for the hidden assumptions for the arrangement of typical Korean housing in intermontane basin that its approach is found to be more appropriate in avoiding shadow conditions, rather than exploring the ideal landform location.
