In the process of distributing blood many troubles are arising. In order to establish a drastic solution, the current distribution must be reviewed as well as its problems must be clearly grasped. This paper introduces RFID(Radio Frequency Identification) system to solve the problems, which arise in the process of distribution, and to systemically manage blood. Among various RFID systems, the reader and tag suitable to the blood distribution are designed. Likewise, through constructing a DB that can cognize electronic tags, objects and blood-distributing RFID system are designed.

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.

물류 산업이 크게 성장함에 따라 유통 및 관리되어야 할 물류량 또한 증가하게 되었다. RFID 시스템은 이에 대한 효율적인 관리 방법의 대안으로 떠올랐다. 하지만 RFID 시스템의 특성상 외부에 노출되어 운용되며, 이에 따라 다양한 외부 요소의 간섭으로 인해 RFID 태그 인지 오류를 야기할 수 있다. 뿐만 아니라 RFID 물류 유통 모니터링에 적용된 RFID 시스템은 실시간 모니터링을 위해 스트리밍 형태로 데이터가 발생하여 인지 오류의 감지가 어렵다. 본 논문에서는 RFID 시스템의 약점을 해결하기 위해 RFID 시스템에서 발생하는 스트리밍 데이터를 대상으로 실시간 오류 감지를 할 수 있는 알고리즘을 제안한다.

본 논문에서는 DRM 기술을 이용하여 소프트웨어의 저작권 및 라이센스의 관리를 위한 온라인 소프트웨어 유통시스템의 설계 및 구현에 관하여 기술한다. 제안된 방법에 있어서 평문 및 인증서 정보, 그리도 전자서명등은 AES 알고리즘을 사용하여 전송하지만, 라이센스는 사용자의 공개키 방식(RSA알고리즘)을 이용하여 전송되기 때문에 불법 사용자에 의한 라이센스 입수가 원천적으로 봉쇄된다. 또한, 라이센스의 지속적인 관리로 인해 소프트웨어 불법 사용 및 불법 배포에 노출된 소프트웨어의 저작권을 보호하는데 매우 유효하다.

DRM 환경 하에서 저작권자, 유통업자 사이에 존재하는 다양한 계약에 따른 권리관리정보가 콘텐트에 부착되어 유통된다. 콘텐트 유통업체는 해당 콘텐트를 다른 유통업체에게 재계약을 통하여 공급할 수 있으며, 이때 재계약되는 권리관리정보가 기존에 부착된 권리관리정보와 충돌이 발생할 수 있는 것이다. 본 연구에서는 콘텐트에 부착되는 권리관리정보 집합을 도출하고, 권리관리정보 사이에 발생하는 충돌 사항을 자동으로 체크할 수 있는 시스템에 대한 모델을 제시하였다.

Customer Relationship Management(CRM) paradigm has emerged that suggests organizations will be more successfully if they concentrate on obtaining and maintaining a share of each customer rather than a share of the entire market, with information technology(IT) being the enabling factor. This paper presents five key elements that provide the necessary steps that allow and organization to position its people, business process, and information system to establish and take advantage of this paradigm. The key elements are : (1) IT investment, (2) Website application, (3) IT System application, (4) Communication strategies, (5) CRM Performance. The results show that IT investment, IT system application, and Website application play a vital role in enhancing an Organizational Communication. Also, the results show that IT investment, IT system application, Website application, and Organizational Communication play a vital role in enhancing an organization's performance of customer relationship management. Further, this paper discusses the importance of integrating these four elements for achieving effective customer interaction. The author provides academical and managerial implication for business strategies.

This study assessed the development of Japanese food distribution system in response to changes in the needs of consumer population the current food concepts can be divided into "processed" and "perishable" foods we expended the current concept introducing "processed perishable foods" and "perishable processed foods", and how this modified term contributed to more effective food distribution system in Japan. We further assessed the effects of changes in the needs and perception in Japanese consumer population on food distribution system, which included PB goods development as well as diversification of chain system. Our study in the development of Japanese consumer population and food distribution system can be compared to that of Korea, providing a direction for systematic and effective food distribution system.

The purpose of this study is to suggest the way of effective use of spatial data in Busan metropolitan city. To do so, information systems and spatial data established in each department are analyzed. Spatial data distribution networks scattered around the nation are integrated to the national spatial information clearinghouse and the service is expanded for the public and the private sectors to participate. Information systems supplied by the central government are 22 and information systems operating in the Busan Metropolitan City are 168. In addition, there are also 295 types of the thematic maps in 11 fields related to the environment, road transportation, livestock, and etc. For systems integration and management system, an integrated information management and linkage system is required in the near future. In the next logical step, generation of metadata, experiments for effective utilization of spatial data, and construction of the data center should be necessary.

This paper describes difficulties for the producer's distribution and the user's acquisition of the spatial data because the circulation of them is complicated according to its kind in Korea. The way to overcome these difficulties would be to develop the clearing house system to incorporate GIS technology on Internet. This research proposes the problem statement, the architecture, and the operating environment of the system. The system contains the functions such as metadata generation, metadata registration, metadata version management, catalogue creation and update, reports generation, forms processing, metadata search, payments, GIS information pool, and spatial data browsing.
