Many organizations have spent huge investments on information systems (IS) but are unable to achieve the maximum benefits expected. The problem of system underutilization of implemented IS is a major factor that causes the lackluster returns on organizational investments in IS. In light of the need for solutions to underutilization, researchers are beginning to explore IS infusion to enhance task performance. IS infusion is the extent to which an individual fully uses the system to enhance his or her task performance. So far, there has yet to be any significant finding or theory to explain the phenomenon. Therefore this study offers a conceptual framework on IS infusion based on the socio-technical system perspective. Particularly, this study investigates the influence of job fit, task competence, technology competence, self-determination with technology and self-determination with task on IS infusion. The analysis following the collection of empirical data found that job fit and self-determination with technology are positively related to IS infusion. This study serves as a basis for future research and suggests important implication to managers and system designers in promoting IS infusion.

The main purpose of this study is to identify the factors influencing the implementation performance of ERP system from the investment such as hardware, software and consulting fee. The main goal of this study to analyze of ERP system implementation in various sections depending on the amount of investment and research about the contribution of ERP utilization on overall PCB business activities. Survey questionnaires were distributed via post and fax to PCB (Printed Circuit Board)Company in Korea. The results of this study can be summarized as follow. First, only 43.1% of respondents implemented ERP system at the enterprise level, which shows that ERP system does not completely play its role as a truly integrated system. Second, companies shows higher satisfaction rate with selectively invested on particular sub-modules. Third, the efficiency of ERP system can be maximized by improving efficiency on core areas through selective investments. Also, this can be maximized by performing overall investments on the general environment in addition to the direct investment on ERP. Lastly, 59.26% of respondents reported that the utilization of ERP has highly significant effects on the contribution of business whereas 29.63% respondents reported as significant effects on the business. These shows positive effects of ERP on the contribution of business.

규칙 탐사는 주어진 데이터베이스로부터 빈번하게 발생하는 패턴들을 발견하는 연산이다. 규칙 탐사 연산을 이용하여 주식 데이터베이스로부터 유용한 규칙들을 발견하고 이를 토대로 주식 투자자들에게 주식의 매매를 적절한 시점에 추천할 수 있다. 본 논문에서는 이러한 주식 투자 시스템에서 질의를 효율적으로 처리하기 위한 저장 구조에 관하여 논의한다. 먼저, 주식 투자 추천을 지원하기 위한 다섯 가지 저장 구조들을 제안하고, 각 구조들의 특징과 장단점을 비교한다. 또한, 실제 주가 데이터를 이용한 실험을 통하여 제안된 저장 구조들의 성능을 검증한다. 실험 결과에 의하면, 히스토그램을 이용한 저장 구조의 경우, 기존의 기법에 비하여 질의 처리 성능이 약 170배 개선되는 것으로 나타났다.

In a competitive environment, selecting and effectively pursing the right information system investments can be a key factor in sustaining corporate viability and prosperity. This study applies quality function deployment(QFD) to the determination of information system development priority. The intent of QFD is to incorporate the needs of a customer through the various stages of product planning and manufacturing into a final product. The basic idea of our study is to translate the core competence and the competitive environment into the business strategy, and the critical success factors, and subsequently into information system development priority. Our method is applied to a motor company for the determination of the information system development priority. The company case is illustrated step by step with real data of the company and motor market.

In this paper, we compared the efficiencies of national R&D investments between NT (Nanotechnology) areas in terms of papers, patents, and commercializations, and found ways to improve the efficiencies of national R&D investments for each NT area. This is in response to huge R&D investments government has made recently in NT areas. Here, we collected data on investments, papers, patents, and commercializations for the R&D projects in NT areas through National Science & Technology Information Service. Based on the data, we analyzed the investment and performances (papers, patents, and commercializations) for each NT area, calculated the efficiency for each NT area, and compared the efficiencies between NT areas. Next, using cluster analysis, we identified several NT areas with similar characteristics in terms of paper efficiency, patent efficiency and commercialization efficiency. Finally, we derived implications for the efficiency enhancement for each grouping. The cluster analysis showed that there could be two groups, one being low in terms of technological outcome (papers and patents) efficiencies and high in terms of commercialization efficiencies, while the other being high in terms of technological outcome (papers and patents) efficiencies and low in terms of commercialization efficiencies. Therefore, the strategy for one group calls for support for technology transfer or technology introduction from other R&D performers and grant of guidance for improving R&D performers' commercialization ability to other R&D performers while the strategy for the other group calls for R&D support for transfer of technology to other R&D performers, activation of technology transfer and support for commercialization of R&D performers.

Today’s information technology departments face a dilemma to create a competitive advantage for the organization by developing. deploying, and managing distributed applications that scale across the LAN, WAN, and Internet, while preserving investments in systems. Applications, information. IT organizations are today being asked to build the future, without breaking systems that maintain the current business. A possible answer to this dilemma is the implementation of a multi-tier distributed computing architecture. Multi-tier architecture has the potential to provide better, more timely information across the enterprise at a lower cost than the current combination of PC LAN, two-tier client/server, or mainframe applications that have been developed in most organizations. In this paper, we implement management information system based on distributed object middleware using multi-tier distributed computing architecture. This system uses Microsoft's implementation of DCOM/ActiveX and provides easily accessible web interface to the system users.
