This paper examined a e-Business utility of on-line shopping mall firms. Based on the literature review and cases study, the following results were found. First, in e-business policy, it was found that partnership between government and market are very important to e-business utility. Second, e-CRM of on-line shopping mall firms should be considered web site design based on commodity, cafe based on experience and information shares, and transaction confirm service. Third, B2C e-commerce model should be contained firm-specific force, customer oriented force, social force, and technology force.

The selected structure for the value engineering review is one section of cut and cover tunnel for Seoul Subway Line 9. The primary focus of the review is on the optimisation of the structures to save cost on the existing Line 9 contracts through variation of the design criteria as it affects the permanent works. This is to be achieved through comparison with design criteria for other selected international subways. Criteria resulting from the review must not compromise public safety and durability for the 100 year design life.

In order to scheme the optimal assumption that satisfies the travel demand, it should be review the elements that affect on determining the headway, which are signal systems, line shape, vehicle(Light Rail Transit) performance, and so on. When applying the conventional signal systems, including Fixed Block System and Moving Block System, It was confirmed whether or not satisfy the requirements of target line with the way of a numerical formula reviewing and Train performance Simulation on the main line, station, depot, and so forth. Therefore, it should be used as references that decide target line and each sub-system after identifying the compliances for Minimum Headway to Moving Block System.

Purpose: The purpose of this study is to propose adoption of QFD and Stage-gate in order to analyze the quality of korea defense system. Methods: Drawing change data of initial production phase in korea defense system were anlayzed and a practical method was proposed. Results: The results of this study are as follows; Off line Quality Control should be introduced in development phase. Specially, in case of defense system, the best method is QFD(Quality Function Deployment) and Stage-gate process. At first, QFD 1 step defines product planning from VOC(Voice Of Customer), QFD 2 step specifies part planning from product planning, QFD 3 step defines process planning from part planning, QFD 4 step defines production planning from previous process planning. Secondly, Stage-gate process is adopted. This study is proposed 5 stage-gate in case of korea defense development. Gate 1 is located after SFR(System Function Review), Gate 2 is located after PDR(Preliminary Design Review), Gate 3 is located after CDR(Critical Design Review), Gate 4 is located after TRR(Test Readiness Review) and Gate 5 is located before specification documentation submission. Conclusion: Off line QC(Quality Control) in development phase is necessary prior to on line QC(Quality Control) in p roduction phase. For the purpose of off line quality control, QFD(Quality Function Deployment) and Stage-gate process can be adopted.

The purpose of this study is to analyze the cost-effectiveness analysis on on-line and off-line extra-curricula education(ECE). Based on a review of relevant literature, on-line ECE is defined as internet based learning, and off-line ECE is defined as on-site learning out of school such as private cram schools and private tutoring. The results of this study are as follows: First, sixty nine percent of the subjects were received ECE. Off-line ECE is more dominant than on-line ECE. Second, cost for off-line ECE is more expensive than on-line ECE. Third, off-line ECE is more effective than on-line ECE, when cost is ignored. Fourth, on-line ECE is more cost-effective than off-line ECE.

국내의 과학기술 관련 학회는 약 660여개에 이르는 것으로 조사되고 있고 새로운 연구 분야의 개발과 기존 학문의 세분화로 신생 학회가 매년 증가하고 있다. 이러한 학회들은 최신 학술 연구 정보로서 논문을 투고 받고 있고 투고된 논문들은 발표되기 전에 심사 과정을 거치게 된다. 대부분의 학회에서는 우편을 이용한 오프라인 방식으로 심사가 이루어지고 있어 논문의 의뢰, 심사, 편집 기간이 길어지고 심사에 통과하여 발표된 수많은 논문들의 효율적인 관리도 어렵다는 문제가 있다. 이에 본 논문에서는 논문의 심사 의뢰 및 심사 과정을 온라인 화 하여 신속하게 심사가 이루어지도록 하고 회원 및 게재 논문의 통합 관리를 통해 제반 업무의 경제적인 처리 및 효율적인 학술 정보 관리가 가능한 온라인 논문 심사 시스템을 설계 및 구현하였다.

Current collection performance on-line tests for a Korean High Speed Train being developed in G7 project is scheduled to start in June, 2002. In this paper, preparatory efforts for measuring contact forces which is regarded as one of major measuring items in the test are introduced. Specifically speaking, review of frequencies related with contact force fluctuations, brief of contact force measuring algorithm, review of measuring instrument specifications and development of a data acquisition program are presented.

The recent stabilization of the Internet is now driving every aspect of life into an Internet presence. In the coming years, the Internet will see growth in numbers unlike the world has ever seen. The subject of this study is the Research Study on the Products Purchase Type of On-line Shopping Mall Buyer. Also, this paper is to examine the relations between customer satisfaction and intensity of repurchase intention and complaining behavior in on-line context. On-line shopping customer depths interview it led and the online afternotes trust evaluation dimension was discovered the of useful characteristic, intention characteristic, exaggerating characteristic and on-line afternotes with or without. From these results, this paper suggests effective marketing strategy to the marketer who plans to run on-line shopping mall in the near future and also to the marketer who plans to sell products through the on-line shopping mall.

This paper addresses the effect of protective capacity on the lead time and throughput of a re-entrant line where statistical fluctuations exist in the form of variation in processing times and machine breakdowns. The specific framework employed in the paper is a five station re-entrant line structured as a closed network mode. This paper argues that protective capacity can be used in conjunction with WIP inventory in order to reduce the lead time and to increase the increase the throughput of a line. Simulation analyses are included to give insight into the effectiveness of protective capacity.
