With the e-business paradigm emerging, the website became a critical resource for most corporations. However, the amount of value creation through internet is still in question. This paper shows the result of an exploratory study on website assessment, following the tradition of Technology Acceptance Model (TAM). We viewed the intended usage as the value of the website and added such factors as playfulness, commitment, system quality, and information security as external variables of the model. Website types, visiting purposes, and the user system quality were included as moderators. The website value could differ depending on website types, purposes of the use and system quality. In the case of internet shopping malls, playfulness, compatibility, website quality were identified as key influencers, while for stock trading users, however, commitment and security factors are more important. In terms of user purposes, information search requires both the compatibility and the website quality. Also the website quality was strongly affected by the user system quality. In other words, any investment of upgrading the website system quality can be meaningless unless the user system quality is improved as well. For each variable considered, empirical results are discussed and practical implications are provided.

As complex mathematical models are increasingly adopted for business decision-making, difficulties arise in reusing solvers (i.e., model solving algorithms) against diverse models and data sets and thus the collaboration among users (model/solver builders and decision makers) in multiple departments becomes very difficult. To facilitate the solver reuse, this paper adopts the Web services technologies as the base technologies for linking the solvers to the models, both of which are created on different modeling paradigms and different system platforms, in unified system architecture. Specifically, this paper focuses on designing an ontology that represents the interfacing semantics of the model-solver interactions in a general and standardized form. By referring to the ontology, a model management system (MMS) can autonomously suggest a set of compatible solvers and apply them to individual models even though the decision makers are not knowledgeable enough about all the details of the models and the solvers. Thus, this Web services based MMS would improve the reusability of the solvers by relieving the decision makers from the risk of erroneous application of a solver to syntactically and semantically incompatible models and the burden of considerable understanding of model and solver semantics.

시간적 금전적 압박으로 최근의 웹 응용에서는 체계적인 시험작업이 종종 간과되곤 한다. 게다가 효과적인 웹 응용 시험 방법이 많지 않아 웹 응용에 기존의 시험 방법들을 적용하면서 개발자들은 많은 어려움을 겪고 있다. 빠르고 효과적 인 시험을 위하여 웹 페이지간의 메시지를 모델링한 UML 순차도(Sequence Diagram)로부터 웹 응용을 위한 시험사례를 추출하는 방법을 제안한다. 웹 응용을 위한 시험사례들은 UML의 순차도에서 자기 호출 메시지 (Self-Call Messages)를 포함한 메시지들로부터 추출된다. 시험사례는 시험할 대상인 메시지와 스크립트 함수, 서버 페이지와 추가적인 시험값들로 구성된다. 또한, 웹 응용 시험을 지원하기 위한 간단한 도구를 제시한다. 이 시험 도구는 웹 응용을 시험하기 위한 URL을 생성하고 이를 실행하여 그 결과를 보인다. 생성된 URL은 시험할 서버 페이지의 주소와 추가적인 시험값들로 구성된다. 이 도구는 마이크로소프트 비주얼 베이직으로 작성하였다. 회원 관리 기능을 수행하는 웹 응용개발 과제에 제안하는 시험사례 추출방법과 시험 지원 도구를 적용하였으며 그 유용성을 확인하였다.

This parer proposes application of quality costing system in quality improvement area. Cost of quality in quality improvement area provides a valuable of both providing the need for improvement and giving a starting point for project. WQCMS(Web-based Q-Cost Management System) have ability to collect and analyze quality data generated from various different departments in the inside or outside of the enterprise without any limitations, if end-users are able to access wide area network. It provides the capability to integrate quality information from database and to generate various easy analysis reports to management's needs using built-in analysis tool modules with real-time. Web-based quality cost management system to measure the performance of quality improvement activities in the business firms. This paper proposes standard model for quality cost process in quality improvement area.

Document retrieval (DR) has been a serious issue for long in the field of Office Information Management. Nowadays, our daily work is becoming heavily dependent on the usage of information collected from the internet, and the DR methods on the Web has become an important issue which is studied more than any other topic by many researchers. The main purpose of this study is to develop a model to manage business documents by integrating three major methodologies used in the field of electronic library and information retrieval: Metadata, Thesaurus, and Index/Reversed Index. In addition, we have added a new concept of eDocument, which consists of metadata about unit documents and/or unit document themselves. eDocument is introduced as a way to utilize existing document sources. The core concepts and structures of the model were introduced, and the architecture of the eDocument management system has been proposed. Test (simulation) result of the model and the direction for the future studies were also mentioned.

Purpose: Present study was designed to examine the casual relationships among web service quality, customer satisfaction, initial trust and off-line visit intention in hospital website. Research object was limited to web service quality of general hospital. We applied path analysis model in order to test the hypotheses and research model. Methods: Survey tool, that is, Questionnaire had obtained validity through literature survey, exploratory survey and pretest and sample 320 was selected. For statistical treatment of pretest and main analysis, SPSS18.0 and AMOS18.0 were employed and Structural equation model was employed as analysis method. Results: Result of this study shows as follows. Factors of web service quality have an effect on customer satisfaction and initial trust, both of customer satisfaction and initial trust have an effect on off-line visit intention. Also customer satisfaction affects initial trust. Especially, customer satisfaction and initial trust were empirically confirmed as the important factors preceding off-line vis it intention. Conclusion: Therefore, present study shows that customer satisfaction and initial trust are important factors that medium and small size hospitals have to emphasize to raise performance. However, present study has some limitations to additionally research in the future.

Assimilation is defined as the extent to which the use of a technology diffuses across organizational work processes and becomes routinized in the activities associated with those processes. Assimilation is an important construct in the casual chain of influence from the organizational adoption of an information technology to the evidence of its impacts on business performance. Given a wide range of experiences with the effective assimilation of Web technologies. there is a need to discover how firms can institutionally encourage the managerial activities that will result in greater levels of technology assimilation. This study analyzes or shows which organizational and strategical factors like management belief. management participation. strategic investment rationale and coordination mechanism have impact on the assimilation of web technologies. Moreover. this research is tried under the different types of firms. manufacturing and service firms. The result shows that the management belief among the determinants had a significant effect on the assimilation of web technology. However. the result would be generalized with the inclusion of the psychological factors to the current model.

본 연구는 기존의 지식경영시스템의 한계요인을 분석하여, 시맨틱 웹 기술혁신이 이들 한계요인을 어떻게 극복할 수 있는가에 대한 방안을 제시하고자 하였다. 기존의 지식경영시스템의 한계요인을 분석하기 위해서는 설문조사 방법을 이용하였는데, 시스템 사용의 시간 및 공간적 한계, 시스템 사용의 불편성, 검색 한계, 통합한계라는 시스템 품질의 한계와 지식의 부적합성/불완전성과 비신뢰성이라는 지식품질의 한계가 비즈니스의 가치흐름에 장애요인으로 작용하는 것으로 나타났다. 또한 본 연구에서는 특히 시스템 한계를 극복하는데 시맨틱 웹이 적용될 수 있다는 것을 지식경영과정이라는 관점에서 분석하고 시맨틱 기반의 지식경영시스템의 개념적 모델을 제안하였다.
