The purpose of this paper is to examine relation between trust building level and linkages's spatial characteristics on the logistics & storage industry of Busan. As a result, First, long-term & repeated interaction, information sharing & reciprocity, and interdependence & asset specificity have an important effect upon the micro trust which implies the highest trust. Proximity and uncertainty impact on the meso trust, the trust of middle level. Culture, norm, and formal institution of firms affect the macro trust, the lowest level of trust. Second, the micro, the meso, and the macro trusts mainly form in the local scale where spatial proximity is great. The higher the trust building levels become, the more spatial dimensions by linkage expand to national and international dimension, respectively. Third, these results appear more clearly in the output linkage than input linkage, in the service areas-many firm, in the horizontal linkage than vertical linkage, in the advanced evolution phases of firm connection, and in the supply chain management than outsourcing.

The purpose of this study is to analyze the spatial characteristics of inter-firm linkages and innovation networks of firms which are located in Gyeonggi border regions. Through this analysis, this study aims at understanding the spatial characteristics of economic activities of firms in Gyeonggi border regions. More importantly, this study focuses on revealing how the spatial characteristics of economic activities of firms affect future growth potentials of firms and regional economic growth. The main findings of this study are as follows. According to the analysis of spatial material linkages, the firms in both footloose location and industrial complex are all proven to be strongly dependent on the Capital Region. Owing to the weak level of the local material linkages, the effects on regional economic growth are limited. But firms in industrial complex contribute more to regional economic growth. The analysis of spatial employment linkages shows that the local linkages are comparatively strong. But the differentiation of residences weaken the positive effects on regional economy. As a concluding remark, the harmony with local linkages and non-local linkages is required to promote future growth potentials of firms and regional economic growth.

This study investigated the agglomeration process of the towel industry in the Daejeon and Chungcheong regions, which are located in the mid-western part of South Korea, focusing in particular on industrial restructuring. Moreover, it aimed to identify the spatial features of the towel industry by analyzing the subcontracting linkages and to discover the implications of such linkages on government policy. The towel industry in the Daejeon and Chungcheong regions began to grow from the end of the Korean War when textile technicians from North Korea settled down in this area, spreading their techniques and know-how within the region. Later, in the 1980s, the industry underwent restructuring when companies within the region strengthened their linkages through corporate specialization based on the concept of social division of labor. Accordingly, the industrial linkages and linkage spaces, as well as characteristics of the industry, should all be considered to develop and implement policies for the regions of the towel industry.

The purpose of this study was to analyze the spacial composition feature of Law School Library and define the feature in spacial planning of law school library. Through the analysis of characteristics in spacial composition, the basic spacial type of law school library will be proposed as a new law school library design. The spatial composition characteristics of Law school Library are as followings. (1) Entry spatial feature for the user accessibility (2) Reference room spatial planning for carrel user (3) Connectivity of educational & research space and reference room space. As the result of design proposal and analyzing the spacial feature, firstly entry common space of library should be planned with reference room space. Secondly, reading room should be linked to the entry level for the user. Lastly, core space should be planned as the vertical connectivity space for the intimately linkage of educational & research space and reference room. And separated accessibility should be considered for direct connection from outdoor space.

The purpose of this study is to analyze the spatial distribution and the linkage characteristics of the warehousing industry in Busan and to provide the policy implications for the warehousing industry in Korean port hinterland. We surveyed the warehousing firms in Busan. Categorizing the warehousing industry into industry types, sizes, and organization types on the basis of the survey, we attempted the point pattern analysis and the proximity analysis using the GIS. The warehousing industry in Busan had changed from a small single-unit firm to a medium or a large firm with a head office or branches. These were distributed in hinterland of North Harbor, South Harbor & Gamcheon Harbor, and Sin-Pyoung & Jang-Rim industrial complex and Sasang Industrial Complex constituting the spatial agglomeration. The warehousing industry in Busan formed the linkages with other sectors of the same logistics to provide manufacturing industries with various other services as well as storage services. The linkages were largely formed in the local scope with spatial proximity, generating the economic gains of agglomeration, which were transformed into the efficiency of the warehousing industry in the local scope to gradually expand the spatial dimensions of the linkages.

This study investigates the spatial distribution characteristics of Korean fashion industries during the last decade, in which the economic geography of fashion industries has changed dynamically with economic globalization and "thus resulted in increased" demand "of" diversification. In particular, this study examines the spatial distribution patterns of fashion industries in the Seoul metropolitan area where fashion industries are highly agglomerated. For the purpose, this study applies Moran's I Index of spatial autocorrelation analysis for seven functional sectors of fashion industries related to fashion production. The global and local agglomeration patterns are examined for each functional sector. The results clarify the distinction in the spatial agglomeration patterns among the seven functional sectors of fashion industries in the Seoul Metropolitan area. Logit models are developed to examine the interrelationships among functional sectors in their spatial agglomeration distribution patterns. By conducting binary logistic regression analysis, we find out how the spatial agglomeration of each functional sector is related to the others.

인공신경망 모형은 복잡하고 비선형의 입력과 출력 관계를 잘 반영할 수 있어서 유출 모델링에 널리 적용되어 왔다. 그러나 인공신경망 모형은 강우나 유역특성의 공간적 분포를 반영하는 것이 어려우며 물리적 개념이 결여되어 있는 단점이 있다. 본 연구에서는 유역특성과 물리적 개념을 반영할 수 있는 물리기반 모형과 인공신경망 모형의 장점들을 조합하여 물리기반 모형의 일 유출량 해석 능력을 향상하기 위하여 SWAT 모형과 인공신경망(ANN)을 연계하였다. SWAT-ANN 연계모형은 두 단계로 구성되어 진다. 첫 번째 단계에서는 관측 자료를 이용하여 SWAT 모형을 보정한다. 두 번째 단계에서는 첫 번째 단계에서 계산한 소유역별 SWAT 모형의 유출결과를 ANN의 입력자료로 이용하여 SWAT-ANN 연계모형을 구축한다. SCE-UA 최적화 방법을 적용하여 SWAT 모형의 매개변수들을 보정하였고, ANN 학습은 3층의 feed-forward 역전파 알고리즘에 기초한 Bayesian Regularization 방법을 적용하였다. ANN 은닉층의 뉴런 및 전달함수는 시행착오를 통하여 적절한 ANN 구조를 설정하여 SWAT-ANN 연계모형의 일유출량을 모의하였다. 여러 가지 통계적 오차기준을 이용하여 보청천 유역에서 SWAT-ANN 연계모형의 결과와 SWAT 단독 모형의 결과를 비교하였다. SWAT-ANN 연계모형이 SWAT 단독 모형보다 더 우수한 결과를 나타내어 일 유출량 해석을 위한 SWAT-ANN 연계모형의 유용성을 확인할 수 있었다.

도시생태환경복원을 위한 녹지기본계획에서 취급되어질 수 있는 녹지유형 구분에 관한 한일비교연구로, 한국의 환경부, 서울시, 울산시의 계획과 일본의 동경도, 오사카부, 아오모리현, 효고현, 가나가와현, 요코하마시의 녹의 기본계획을 참고로, 녹지공간의 구분기준에 대한 고찰을 행하였다. 그 결과내용은 다음과 같다. 한국에서의 녹화공간의 구분은 녹지 공간배치를 중심으로하는 시점에서의 공간 구분을 행하고 있어, 공간 위계질서 체계를 구축함에 유용한 구분으로 되어있다. 이와 달리, 일본에서의 녹화 공간구분은 관련법규와의 연계성을 고려한 행정적인 시점에서의 공간 구분을 행하고 있어, 실현성 높은 공간 구분으로 행정적인 관리체계에까지 일괄적인 연계가 가능하도록 고려되어 있다. 또한, 도시공간의 동일한 지역구분을 하고 있으나, 그 지역 내의 특성을 살릴 수 있도록 세부지역을 구분하여 지역성을 남길 수 있는 유연성을 갖고 있다. 이와 같은 점을 종합적으로 검토한 결과. 비록 법적인 체계 정립이 미비한 한국이지만, 녹화의 계획적인 면보다는 행정적으로 실질성을 가질 수 있는 녹지계획의 관련법규 및 규제 등을 고려한 공간유형구분이 보다 유용하다는 것을 시사하고 있다.
