The GIS Network consists of the Clearinghouse Network Gateway and Clearinghouse Node and Geo-spatial Data Server. Recently with the development of Information and Network technologies, GIS Network should be needed to be more secure than ever. In this paper, we proposed the effective access control method for the distributed GIS network. PKI (Public Key Infrastructure) Technologies are used for access control and security for transmission on Geo-spatial data

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.

The architecture of the National Geo-spatial Information Clearinghouse Network (NGICN) is suggested in this paper. We described the function and relationship of six elements of the NGICN. The elements are clearinghouse network gateway, clearinghouse node, geo-spatial data server, communication network, protocols and standards, and clients. The NGICN suggested in this research will prevent the duplication and improve the value of the database, and persuade the institutes or enterprises in the private sector to participate in producing the geo-spatial database. Finally it will setup the business of producing, circulating and utilizing the geo-spatial information as a new bases of Info-Communication Industry.

The National Geographic Information Clearinghouse (NGIC) in Korea has been established to share dispersed geographic information in many government organizations. The NGIC has become a main hub for sharing and exchanging geographic information in Korea. However, due to rapid technological advancement, citizens not only require more information but also demand more functions for NGIC. In this regards, this research tries to find the way of developing NGIC from a means of 'information sharing' to an arena of 'information use'. To do so, it suggests new technical frameworks and functionalities for NGIC. Then it recommend policy measures to improve current NGIC.

Recently, brisk up the construction of the spatial information, many people highly concern to tile information circulation of GIS. Each system like GIS has a structure of the information circulation to itself. In this paper, we study on the performance evaluation method of tile structure which to circulate tile spatial information based on the internet. To do this, we hypothesize values of content and scale of the geo-spatial information on each internet network and volumes of the information to circulate between internet networks. Then we suggest a method to evaluate the performance of the structure to aid the circulation of spatial information based on queueing model. Henceforth, with the volumes of data stored and circulated information of each GIS, this method can help to design the structure to circulate the GIS information more efficiently.

According to rapid evolution of technologies, recently Standards Developments Organizations(SDOs) In the field of Information and Communication recognize that More new and more complex standards should be developed in shorter time. To cope with this challenge, we propose the functionalities and development directions for implementing standardization information system. Also this paper describes the architecture of the next generation system for standard information that enabling information sharing and exchanging using XML.

Form, increasing the income of fishermen and internationally competitive high value-added seafood merchandising consumers for the purpose of improving the reliability of the food as do Tongyeong Gyeongsangnam-piping of the high quality marine products traceability system for farm businesses. Real-time traceability of the seafood supply chain to manage RFID technologies and related IT technology was introduced in progress. In this study, real-time traceability of fish introduced to the features of RFID technology and to recognize its effects. And efficient distribution system of fish suggests ways to improve and execute simulation about supply chain.

글로벌 시장환경체제에서 유통구조가 복잡해짐에 따라 제조사에서 유통업체 및 소비자까지 아우르는 전체 공급망에서 제품에 대한 이력추적관리는 투명한 유통구조를 형성시킬 뿐만 아니라 더 나아가 소비자들의 안전에 지대한 영향을 미친다. 세계보건기구(WHO)에 따르면 선진국에서 부정 전문의약품의 유통비중은 전체 의약품의 1% 정도이며 이를 미국에 적용할 경우(2006년 기준), 미국에서 유통된 34억 개 전문의약품 중 3,400만 개의 전문의약품이 가짜일 가능성이 있는 것으로 보고되고 있다. 이로 인해 미국 캘리포니아주에서는 유통망의 투명성과 소비자의 안전을 보고하기 위하여 2D 바코드나 RFID(Radio Frequency IDentification)를 통해 의약품 제조에서 약국까지의 유통과정 계보를 추적할 수 있도록 제약기업에 2015년부터 제품에 시리얼번호를 부착한 이력장치(serialized e-pedigree)를 시행할 예정이다. 따라서 본 연구에서는 국내 외적으로 물류/유통과정에서 제품의 위 변조를 예방하기 위한 e-pedigree에 현황 및 동태를 파악하고 국내 e-pedigree에 대한 방향성을 고찰하는데 그 목적이 있다.

각 계열사별로 구축된 음성, 데이터, FAX,화상 등을 복합적으로 결합하고, 생산에서부터 유통, 판매, 재고관리 등은 물론 계열사간 정보유통간 경영자의 의지결정에 기여할 수 있는 그룹 통합망구축이 활발하다. 그룹 통합망의 구축 동향과 그 사례를 살펴본다.
