본 논문에서는 인터넷 기반의 새로운 DSS 개념인 인터넷 DSS 개념적인 설계를 제안한다. 제안하는 인터넷 DSS는 인터넷 환경에서 효과적으로 구동될 수 있도록 지능형 에이전트(Intelligent Agent)를 주요 구성모듈로 하고 있으며, 네트웍 통신층, 문제해결층, 그리고 사용자 인터페이스층 등 다층구조를 갖고 있다. 인터넷 DSS 가능성을 구체적으로 보여주기 위하여 기업내에서 전략적으로 가장 첨예한 대립관계를 보이고 있는 마케팅 부서와 생산관리 부서간의 전략적 통합문제에 적용하여 그 의미를 분석하였다. 이는 최근 기업경영이 글로벌화 되어가면서 마케팅과 생산기능이 지리적으로 떨어져서 운영되는 것이 일반화되어 가고 있기 때문에 기존의 DSS보다는 인터넷 DSS가 이러한 경우에 훨씬 적용가능성이 높기 때문이다. 본 논문에서는 인터넷 DSS를 구성하는 모듈중에서 주로 모형에이전트의 모형결합 메카니즘을 중심으로 설명하였고 결론부분에서 향후 연구방향을 제시하였다.

Although numerous models and solution algorithms to design efficient distributed databases have been developed, very few have been validated for their effectiveness. In this paper, we develop a simulation system which can be used to analyze and validate the average response time of distributed database designs. Our simulation system models comprehensive query processing strategies such as semijoin as well as a concurrency control mechanism We analyze and validate an average response time distributed database design model using our simulation system.

This study presents the growth strategy of outsourcing service by finding out the differences of importance between user firms and system integration(SI) firms in Korean outsourcing business, The result of data analysis reveals that there are siginificant differences between user firms and SI firms in some components of information systems(IS) outsourcing services. User firms regarded integation of distributea data centers as the prominent issue of IS environment changes. Meanwhile, SI firms chose management of IS/VAN center, office automation(OA), and management of global network, as the more important issues in the application area of outsourcing. Among the merits of outsourcing, both of them considered cost reduction and IS flexibility as the most important factors, However, they chose the difficulty of management control and the lack of operation knowledge among the demerits of outsourcing, Also, they commonly selected overall IS consulting among the components of outsourcing diffusion. In the question of future outsourcing services, user firms chose the adoption of client/server architecture, while SI firms selected the application of multimedia. These results show that there are some differences of preference between user firms and SI firms. Most of user firms consider the outsourcing to maximize information utilization, while the service suppliers focus on new IT adoption and its application to organization. For the strategic use of outsourcing services, SI firms are required to establish the diffusion strategy to meet the outsourcing needs of user firms.

Recently, strategic information systems planning (SISP) has emerged as one of the necessities in 15 activities and organizational operations as a whole. Although various SISP researches have been done, in few studies have attention been given to the process employed in organizations to plan and implement SISP. To address SISP problems in terms of the process-oriented view, this paper employs a dynamic viewpoint on the basis of innovation-process model As a result of in-depth interviews with IS managers of nine Korean banks, this research found slightly different problems appear in each stage of the process. While problems cited in prior researches were observed, new ones are also appeared such as "finding out relative outsourcers" "political problems between functions which lead the process and others which alienated," the "necessity of steering committees, etc. Meanwhile, problems such as "top management concerns" or "cost," which suggested as significant problems in prior researches, appeared relatively insignificant This study has limitations as a qualitative and exploratory one. However, in view of further studies, the linkage between SISP practices and innovation process theory will allow researches linking characteristics of both fields. Furthermore, researches which view the SISP process as a comprehensive knowledge transfer process will be possible.

This study, drawing upon research in innovation theory and Information systems, investigates the relationship among the organizational and innovation characteristics and the extent of internal and external diffusion of EDI in Korean firms. The data for this study were collected from 131 firms that have implemented EDI. The results of the correlation and the multiple regression analysis show that elapsed time and organizational compatibility are the major predictors of EDI diffusion. Specifically, the extent of communication, elapsed time and organizational compatibility are the major predictors of internal diffusion, while centralization, organizational compatibility and elapsed time are closely related to external diffusion of EDI. The results of this study imply that to facilitate the use of EDI widely within and beyond organizations, EDI system should be compatibile with the organizational tasks, values systems and existing information systems.

Pricing information services, where congestion can threaten the efficient operation of information systems, has been studied in economics and information systems literature, Recent explosion of the Internet ana proliferation of multimedia content over the Internet have rekindled the research interest in designing pricing schedules for differentiated information services, In order for the information system to effectively serve users having heterogeneous needs, pricing rules for discriminated services should be considered. At the same time, when individual users' interest does not align with that of the organization that individual users belong to, organization-wide pricing policy should be devised to improve the value of the services rendered by the system. This paper, using a priority queuing model, addresses the need for such on incentive-compatible pricing for different information services.

As information is the critical resource of business, CIOs(chief information officers)' managerial roles become more important. CIOs work out the organization and information system strategies, introduce changes into organizations, communicate with chief executive officers and users, and take the responsibilities of the information system operation. The CIOs' managerial roles make affects on the information system performance and the organizational effectiveness. They are divided into six sub-roles; leader, liaison, entrepreneur, monitor, resource allocator and spokesman. The CIOs' influences on organizations are evaluated by information systems performance. User information satisfaction is one of the most valid information system evaluation criterions. User participation and user involvement are regarded as the antecedents of user satisfaction. This study investigates the effect of CIOs' managerial roles on user satisfaction, user participation, user involvement, CIOs' six managerial roles do not equally influence users. The results of this study have implications for the CIOs' managerial roles in organizations. As CIOs effectively perform managerial roles, user satisfaction is improved.

Thie study examines MIS researchers, research themes, methodology, and intellectual structure in order to analyze general research patterns in the field of MIS. The methods used for this study are subject analysis of the journal articles, citation analysis, and author co-citation analysis, The source articles are all the papers in $\lceil$Journal of Korean MIS Society$\rfloor$ and MIS papers in $\lceil$Korean Management Review$\rfloor$ and $\lceil$Journal of Korean MS/OR Society$\rfloor$. In results, core journals in MIS are MIS Quarterly, Management Science, and Communications of ACM. Core authors inlcude Ives, DeSanctis, Ginzberg, Lucas, Rockart, and Davis. The major areas in Korean MIS research turn out to be information system management, DSS/GDSS strategic information systems and AI applications.

Data semantics is an well recognized issue in areas of information systems research. It provides indispensable information for management of data, It describes what data mean, how they are created, where they can be applied to, to name a few. Because of these diverse nature of data semantics, it has been described from different perspectives of formalization. This article proposes to formalize data semantics by the processes that data are created or transformed, A scheme is proposed to describe the structure that data are created and transformed, which is called Bill of Data. Bill of Data is a directed graph, whose leaves are primary input data and whose internal nodes are output data objects produced from input data objects. Using Bill of Data, algorithms are developed to compare data semantics.
