Network Flow has been playing important role in the modern industrial society. No matter what people or company run the network, both of them can't avoid circulating goods among the many branches. But in practical situations, not only the price rising in network increase the transportation costs, but the huge traffic flow volumes increase the transportation costs. Given to such a network environment, how to flow goods in the network is very important. In this paper, the MAX-Flow algorithm will be applied to network flow in order to maximize the network flow volumes. As far as the functions of network are correctly provided, the optimized network system always can make the flow process efficiently.

While a number of studies have recognized the importance of environment of channel systems and consequences of changed environment, only limited studies have dealt with this issue theoretically and practically. The purpose of this study is to empirically validate whether one dimension of environment, called dynamism, has an influence on the relationship characteristics such as transaction specific investment, opportunism and conflict or not; further, it is designed to delve into whether these relationship characteristics have any influence on one crucial relationship quality, 'trust' and its two constituent dimensions - credibility and benevolence. In order to provide empirical validation, a survey was conducted to 163 sales office managers at a major newspaper publisher in Korea. An analysis of the data retrieved from this survey indicated that while environmental dynamism has a positive influence on the publisher's opportunism and conflict perceived by the sales office managers, it did not show a direct influence on the transaction specific investment made by the publisher. Furthermore, while publisher's transaction specific investment had a positive influence on the credibility and the benevolence respectively, publisher's opportunism and level of sales office conflict had a negative influence on the credibility and the benevolence respectively. Currently, a publisher is facing an unprecedentedly dynamic environment. This study should provide ample implications for the publisher in establishing trust, which is a crucial condition in developing and maintaining a long-term successful relationship with its sales offices.

Recently, in the process of distribution industry's growth, distribution environment is changing rapidly by appearance of new business condition and strategy of multiple store. According to the intensification of competition, recently large discount stores are developing private brand(PB) products for the purpose of product differentiation and profitability. But after the economic crisis in 1997, young housewives and salaried man's that have rational and practical buying pattern become the core consumer's in the large discount stores. Hence low price strategy is not new things for the consumer's anymore. In addition to, acquiring new consumer, many discount stores are establishing new stores at the rural area. But they undergo hardships of establishing new stores at the rural area because of disparity consumer's behavior, income level and consumption's pattern among regions. So, when they try to establish new stores, they need to know consumer's behavior at the region. Therefore the purpose of this study is to analyze preference property for the private brand(PB) of large discount stores in Gyeonggi-Do.

지적정보는 정보자체가 가지는 높은 보안과 고유의 특성으로 인해 유통 및 활용에 어려움이 있고, 타 기본공간정보와의 융복합을 위한 상호운영성이 미흡한 실정이다. 하지만, 정보의 개방과 통합은 당연한 시대적 흐름으로서 개방과 통합의 범위는 점차 확대되는 추세에 있다. 최근, 정보의 공개 및 유통을 효율적으로 지원하기 위해 공간정보에 대한 인프라 즉, 표준에 대한 논의가 활발히 진행되고 있다. 정보간 융복합과 서비스 측면에서 다양한 분야별로 많은 표준들이 개발, 운영되고 있는데, 특히, 메타데이터 표준이 관심의 대상이 되고 있다. 정보의 유통 및 서비스를 효율적으로 지원하기 위한 메타데이터 표준은 정보에 대한 정확한 설명을 제공하고, 사용자가 정보를 선택하고 활용하는데 도움을 줄 수 있는 부가정보를 제공하는 중요한 역할을 수행한다. 따라서, 본 연구에서는 지적정보가 다양한 분야에서 활용되고 수요가 창출될 수 있도록 한국의 환경에 맞는 지적정보 메타데이터 표준(안)을 설계하고자 한다. 지적정보의 특성을 감안한 메타데이터 표준의 구성을 통해 정보의 유통 및 서비스를 조기에 실현하고, 타 공간정보와의 융복합을 통한 시너지 창출 및 국가 기본공간정보로서의 역할을 충실히 수행할 수 있을 것으로 기대한다.

This paper deals with the method which can apply spatial-data warehouses into the spatial data infrastructure in the view of clearinghouse. First, we classify the type of available data warehouses in the consider with patterns and properties of spatial data infrastructure. Then we suggest strategies for building and expanding data warehouses into various organizations. After considering all the factors, we suppose how the national spatial data warehouse come into being.

The Competitive power of the country in knowledge information can be determined that how efficiently useful knowledge and information can be circulated. Korean government established the second National GIS Master Plan, and constructed National Geographic Information Clearinghouse to the goal 'whole nation's internet circulation of the geographic information and practical use'. But every departments of government are trying to circulate their geographic information individually, And this case, consumer group should approach to several dissemination network in various routing line to get the geographic information. In fact, it is difficult to present the solution for uilified single dissemination network. It is difficult to present suitable linkage plan coinciding in special environment and characteristics of all systems. Consequently, in this study, we suggested linkage element that should consider far link with National Geographic Information Clearinghouse, and presented linkage plan by linkage target type.
