The objective of this study is examining regional differentiation of private brand customer. Factors found to influence private brand purchase intention included familiarity with private brand, perceived value, store loyalty, perceived risk, perceived quality variation between national and private brand products. For testing the research model, data were collected in Seoul and Busan. The hypothetical paths included in model are supported. There are regional differentiations in 1) negative relation of perceived quality variation and perceived value, 2) positive relation of familiarity and purchase intention, and 3) positive relation of store royalty and purchase intention.

The intrusion detection system is one of the active fields of research in wireless networks. Intrusion detection in wireless mobile Ad hoc network is challenging because the network topologies are dynamic, lack centralization and are vulnerable to attacks. Detection of malicious nodes in an open ad-hoc network in which participating nodes do not have previous security association has to face number of challenges which is described in this paper. This paper is about determining the malicious nodes under critical conditions in the mobile ad-hoc network and deals with security and vulnerabilities issues which results in the better performance and detection of the intrusion.

The goal of this study is to propose the plan for strengthening organizational competences related to the collection development function of the national library. For this goal, author analyzed and compared the organizational characteristics of departments for legal deposit in national libraries of nine developed countries, derived the limitations and weaknesses of legal tasks, policy documents, and collection development tasks by organizational units of the National library of Korea. Based on these results, author suggested the centralization of collection policy and legal deposit function, th name change and total restructuring of collection acquisition division, and its manpower reinforcement, etc.

GIS technique enhanced a space data manipulation ability and we are offering a geographic information service through various analysis. The quantity used of the water was increased in such situation according to a population increase and a city concentration phenomenon. But, to secure clear water are difficult, owing to the water shortage phenomenon, seepage and the quality of water change for worse. We decide the seepage and the system to retrieve the seepage location using GIS in order to reduce vast loss from the seepage. In this paper we proposed Leakage Sensing System using TDR technology in GIS, constructed a GIS database and pilot system to prove the validity, and simulated it using TDR in GIS.

Because of the gravitation of population toward large cities, a number of masonry buildings have been constructed since 1960's. They have been rapidly deteriorated as time passed by. Therefore the purpose of this paper is to present basic data on timeworn masonry buildings which were managed by the Jung, Mapo and Dobong district in Seoul Metropolitan and to analyse their deterioration factors as well as interrelation. Through this study, masonry buildings have many problems with foundation and crack is the most effective to deterioration. Also, the store buildings are the weakest structure type and the structure grade have an interrelation with occupancy type mere than any other factors.

The area of informatization in small business industry consists of production automation. management automation, and network. This paper mainly deals with the management automation which uses management information systems. Functionally speaking, there are four broad categories such as manufacturing, marketing. human resource, and accounting. However, since most of small business industries emphasize more on the manufacturing and marketing, an integrated information system with these two core processes has been developed based on object-oriented methodology. The system, one of the important steps in the stage model this paper proposes, has not only simple and essential features ensuring easy implementation, but also friendly interface and good modularity based on the object-oriented paradigm.

In order to support quickly increasing mobile traffic and deal with various types of users of wireless mobile systems under overlay convergent cognitive networking environments, it is highly required to improve the performance and the capability of the wireless access networks. With distributed antennas and distributed processors, it is possible for mobile terminals (MTs) to monitor interference and control system effectively to minimize mutual interference among users and cells. Virtual cell changes as the MT moves or the environment changes, so no handoff is needed in connections with base station hotelling. In this paper, the characteristics of wireless distributed systems under the overlay convergent networks will be investigated.

현재 우리나라의 일반 서장우편 물량은 매년 증가하고 있는 추세이며 특히 월말이나 연말에 집중화되는 계절적, 순환적 특성을 보인다. 그러나 집배원의 인력 부족으로, 우편물량의 증가와 계절적, 순환적 우편물 집중 현상에 적절히 대응하지 못하고 있으며, 이에 따라 서비스의 질적 저하 업무 부하량 증가 등의 문제가 점점 더 가시화되어가고 있다. 이러한 상황에서 신속한 우편물 처리와 집배원의 업무 경감 등을 위해 우편물 자동 처리를 위한 순로구분 시스템의 도입을 검토하고 있으나, 우편물에 기입되는 주소 기재 방식이 일관적이지 않고 표기 방식이 다양하여 이러한 자동처리시스템의 효율이 떨어질 것으로 예상된다. 따라서 본 논문에서는 향후 도입될 예정인 순로구분 시스템의 자동처리 효율을 높이기 위해 우편물에 기입하는 주소의 표기 표준화 방안을 제시하고자 한다. 이를 위해 우선 국내 우편주소 체계와 주소 표기의 현황을 살펴보았으며, 자동주소인식에 적합한 주소 표기를 위한 고려사항들을 주소 표기 표준화 관점에서 제시하였다.

오늘날 도시인구집중화 현상에 따른 대규모 도시개발과 도시역의 확대로 지표면의 피복 변화가 극심하게 이루어지고 있는 한편 이러한 현상으로 인해 도시의 내 외적 경관변화 뿐만 아니라 지형 및 기온상승, 바람장의 변화 등 복합적인 국지기후 변화를 초래하게 되었다. 본 연구에서는 이러한 도시의 기후 변화에 따라 청계천 복원 전의 도시 지표 열 환경 특성을 분석을 수행하고자 한다 도시지역의 열환경 분석을 위하여 기존에는 주로 Landsat TM/ETM+ 위성영상 자료를 사용하였으나 2003년 5월 위성 센서의 고장으로 위성영상 자료의 사용이 불가피하게 되었다. 이에 대체 방안으로 ASTER 영상 열적외 센서에서 취득한 지표온도 값과 현장에서 취득한 AWS자료와의 상관성 분석을 실시하였으며, 이를 기반으로 청계천 주변의 근접성 분석 및 토지이용별 지표온도 분포 패턴 등 도시 열 환경 변화 탐지 및 분석을 위하여 GIS 및 RS 분석을 실시하였다.

This case study for a homeshopping company shows that the management of returned apparels by the partnership system increases the velocity of the returned goods, which not only minimizes the products' value loss but also improves the company's management performance. By incorporating the partnership system, following significant performance improvements have been identified: First, decrease in transaction cost and time between the homeshopping company and the partnering companies. Second, concentration of production line, accurate schedule management of receipt/delivery as well as collection of goods. Third, improvement of efficiency in procedures of returned goods and quality improvement of product provided by the partner.
