Spatial distribution analysis of industrial locations plays a very important role in the establishment of relevant spatial policies and plans. The first thing to consider in this analysis is what analysis indicators and spatial units are used, because the interpretation of the analysis results may vary depending on the analysis indicators and the spatial units. Therefore, this study first examines various industrial integration indicators considering spatial autocorrelation and suggests the classification of regional types of industrial aggregation through the combination of related indicators. And then, this paper aims to empirically analyze the root industry by presenting a methodology for analyzing industrial integration by various spatial units such as individual locations, grids, and administrative districts. The results of the empirical analysis show that the grid in the spatial unit can be analyzed in more detail than the administrative unit. In addition, it is expected to overcome the limitations such as differences in interpretation that may occur due to the setting of spatial units. In the classification of regional types, the south-eastern region of Ulsan, Busan, and Changwon, and the western region of the SMA of Incheon, Hwaseong, and Ansan were analyzed as the industrial cluster type.

The foodservice franchise is preferred by the founders who inaugurate a business enterprise, because it is not difficult to convert into money more than other private enterprise. The success or failure of the foodservice franchise depends 80 percent on its location. Therefore, this research aimed to study the location factors of the first shops of foodservice franchise in Seoul through the analyses of nearest neighborhood effect and statistical relationship between variables. According to there results, the location characteristics of the first shops of foodservice franchise are summarized as in the following three items. First, the spatial distribution pattern of the first shops is a clustered type. Second, the first shops relate to the 15 variables which are the number of financial facilities, the number of business service offices, and the number of hotels and restaurants, etc. Third, the main location factor of the first shops is the number of financial facilities. In conclusion, it is estimated that Gangnam-gu and Jung-gu might be good for the location of the first shops of foodservice franchise in Seoul, because these two places have many financial buildings.

산림 사면에서의 토양층 수문반응은 물순환을 이해하는데 중요하다. 본 연구에서는 토양수분자료를 이용하여 토양수분의 계절적, 공간적 변화를 분석하였다. 연구대상지역은 경기도 파주시 적성면 설마리의 설마천 유역 내에 위치한 범륜사사면과 충청북도 음성군의 청미천 유역내의 수레의산사면이다. 정밀측량을 통해 획득한 수치고도모형(Digital Elevation Model, DEM)을 이용하여 관측지점들을 각각 선정하였다. 대상사면에 토양층별 토양수분의 분포변화를 분석하기 위해 각 지점별 10, 30, 60cm에서 토양수분량 측정시스템(Time Domain Reflectometry, TDR)방식의 토양수분측정장비(miniTRASE)를 설치하여 2시간 간격으로 2014년 3월부터 12월까지 토양수분을 측정하였다. 각 지점별 사면에서 획득된 토양수분 시계열자료는 토양수분의 시공간적 분포특성을 파악하기 위해 지점별 토양수분량의 통계분석(평균, 표준편차, 변동계수)를 수행하였다. 설마천유역의 범륜사사면에서는 2014년도에 특히 강우량이 적어 토양수분의 평균과 표준편차의 월별 변화에서는 기저토양수분 값을 주로 유지하고 강우에 대한 변동성이 크지 않은 것으로 나타났고, 청미천유역의 수레의산 사면에서는 시간적 토양수분변화는 계절적 강우분포 패턴에 따라 반응이 나타났다. 청미천유역의 토양수분자료를 이용하여 토양수분의 계절적, 공간적 변화를 분석한 결과 지표근처 토양층(10, 30cm)와 저층(60cm)에서의 공간적 변화특성이 다르게 나타났다. 이는 저층(60cm)에서의 지표하 흐름, 기반암 존재의 영향차이에 의한 것으로 판단되고, 사면의 위치에 따라 토양수분의 안정화 정도가 다른 것을 확인할 수 있다.

In this paper, we introduce the analysis and counter-measure of signal distortion of search radar equipped on the ship. Using ShipEDF program, the search radar's main antenna and ship structures are modeled in the view of electromagnetism. Ray tracing method is used for analysis of the search radar's radiation patterns in free space and ship condition. From analyzed radiation patterns, we can conclude that the search radar's signal distortion is due to radiation pattern distortion. We also analyze the surface current distribution of the mast to propose the counter-measure to reduce electro-magnetic field reflection of mast.

The purpose of this study is to analyze the spatial characteristics of travel patterns and travel behaviors of transit users in the Metropolitan Seoul area. We apply the data mining techniques to explore the travel patterns of transit users from the T-money card database which has been produced over 10,000,000 transaction records per day. The database contains the information of locations and times of origin, transfer, and destination points for each transaction as well as the informations of transit modes taken via the transaction. We develop an data mining algorithm to explore traversal patterns from the enormous information. The algorithm determines the travel sequences of each passenger, and produce the volumes of support on each points (stops) of transportation networks in the Metropolitan Seoul area. In order to visualize the spatial patterns of travel demands for transit systems we apply GIS techniques, and attempt to investigate the spatial characteristics of travel patterns and travel demand. Subway stops located in the Gangnam area appear the highest peak for the travel origin and destination, while the CBD in the Gangbuk stands at the second position. Two or three sub-peaks appear at the densely populated residential areas developed as the high-rise apartment complex. Subway stations located along the Subway Line 2, especially from Guro to Samsung receive heavy travel demand (total support), while bus stops located at the CBD in the Gangbuk stands the highest travel demand by bus.

This paper analyzes the social cohesion effects of creative industrial as a core role player of emerging new economic paradigm of the creative economy using the case of Seoul Metropolitan Area(SMA) that is a typical cluster of creative industries in Korea. This study reclassified the creative industries in a Korean context into 13 industries in 6 sectors. Based on this reclassification, the study found out that the spatial pattern of creative industries in SMA is spatially much differentiated in terms of specialization, which demands more differentiated cluster strategy with different policy mix. This paper also investigates the social cohesion effects of creative industries using structural equation modelling. It turns out that the growth of creative industries is likely to contribute to the regional development capacity and also to provide positive effects on various aspects of the social cohesion.

This paper intends to identify the structure of homogeneous regions and functional regions in Seoul based on B.J.L. Berry's ‘general field theory of spatial behavior’. The structure of homogeneous regions by using socio-economic variables can explain how the structural elements of the city are arranged. It can be ssid that Seoul has shifted towards more complicated and differentiated features in terms of homogeneous regions. The different patterns are found between the northern part to Han River where old torn areas are located and the southern part to Han River where newly urbanized areas are located. Usually, the concentric pattern and the sectoral pattern coexist, which is enhanced moving from CBD to the outskirt area. The distribution of different social classes shows irregular pattern similar to the variation of living environment. The social gap is expected to be more widening between new towns and old towns. The analysis of spatial movement pattern shows no clear hierarchical order because of current shifts towards both multi-nuclear pattern and spatial dispersion. The functional regions show duplicated structure overlapping their boundaries each other. The ‘general field theory of spatial behavior’ strongly suggests that spatial interactions among sub-areas in the city are differentiated from the basic characteristics and function of each sub-area. The attributes of homogeneous regions and functional regions are interrelated in the characteristics of isomorphic nature.
