As the main stream of electronic commerce changes from B2C to B2B, the importance of a strategic web site design is being recognized more than ever. In this sense, this study proposes a new approach to an adaptive design of the web site by using the stratified fuzzy cognitive map (FCM). Its main virtue lies in capability of changing specific components on the web site with its subsequent effects upon other components being objectively considered. By doing so, we can maintain total effectiveness of the website design. This advantage of the proposed approach can be compared with the traditional approach where the web site design has been changed without paying a due attention to the related components. We gathered 134 questionnaire responses. By analysing the questionnaire results, the causal weights of the FCM were computed objectively. Then the FCM was transformed into a stratified FCM by using Lee & Cho (1998)`s approach. On the basis of the stratified FCM and four scenarios, we performed web site design simulation. The simulation results showed that the proposed approach could be used effectively for analyzing the web site design in an adaptive manner when the market situation is changing.

As the advent of the Internet, B2B negotiation process on the Internet has been given attention from both researchers and practitioners. However, literature still shows that only structured conditions have been explicitly considered, despite the fact that unstructured conditions should be rendered as well. In this sense, this paper proposes a new negotiation support mechanism to incorporate causal relationships between structured and unstructured conditions in the process of B2B negotiation. Fuzzy cognitive map was used as a main source of causal knowledge as well causal inference engine. A prototype named CAKES-NEGO was developed to perform experiments with an illustrative example. Results revealed the robustness of our proposed negotiation support mechanism.

본 연구의 목적은 인터넷비즈니스 과목에서 교수-학습모형의 개발하였다. 이를 위하여 교수-학습 방법에 대한 기존문헌 연구를 통하여 교수-학습에 사용되는 주요한 변수를 도출하고 이를, 실제 인터넷비즈니스 수업을 수강하였던 학생들을 대상으로 설문을 실시하였다. 또한 이 요인들간의 인과관계를 구조등식모형으로 설정하고 실제적으로 설문을 통하여 분석하고 증명함으로써 교수-학습에 대한 새로운 인과모형을 제시하였다. 이렇게 도출한 인과모형을 중심으로 교수자와 학습자들의 인지지도를 작성하게 하였으며, 이를 반영하여 최종적인 교수-학습모형 (Cognitive Instruction-Learning Model: CILM)을 개발하여, 다양한 문제를 시뮬레이션을 통하여 해결방안을 제시하였다. The objective of this study is to propose the cognitive instruction-learning model for the “Internet Business” class which is currently being lectured in many universities. It is well known that students have different view from instructors in the class, causing unexpected inefficiency in communication between students and instructors. However, the previous studies fail to show concrete and unified resolution results on this issue. To fill the research void like this, this study proposes applying the cognitive map to coordinate different views of both instructors and students, and derive an effective education paradigm. The cognitive map is induced from statistical results using LISREL and 596 valid questionnaires from active students studying the Internet business subjects. Four scenarios are conducted to show how effective the proposed cognitive instruction-learning model is for the “Internet business” class. The results reveal that the proposed education mechanism is valid and robust for teaching the Internet business. Besides, we find that the results of this study can be easily extended to other similar research issues.

This Paper is aimed at Proposing KMPI (Knowledge Management Performance Index) for evaluating the knowledge management performance of venture businesses. In the aftermath of the frenzy about using the Internet technology in management, knowledge management became a popular management technique because knowledge circulation Process (KCP) within an organization, which is believed to support work process Positively and contribute to creating corporate memory, can be facilitated much more smoothly and fast with the Internet technology being actively adopted as a main telecommunication vehicle. KMPI depends on the qualify of knowledge circulation Process which typically consists of five steps such as knowledge creation, knowledge accumulation, knowledge sharing, knowledge utilization, and knowledge internalization. Especially, venture business is known as active in its knowledge circulation process, However, literature about studying KMPI for evaluating knowledge management Performance of venture businesses does not exist. In this sense, we propose KMPI in a statistically sound way. questionnaire survey was conducted extensively among a lot of venture businesses listed in KOSDAQ. Statistical results were suggested Proving that the proposed KMPI has a significant relationship with typical financial performance measures.

Six sigma’s concept has long been used as an effective way of restructuring the management process of a firm. In literature regarding six sigma, a number of successful cases were reported, where six sigma-based management activities could enhance firm’s strategic performance dramatically for years. However, there exist very few researches investigating the effect of six sigma on corporate competitiveness. Especially, researchers as well as practitioners need more rigorous results about such issue-how much the six sigma strategic initiatives may have an influence on the firm’s competitiveness. In this sense, we need the empirical study adopting statistical approaches at this time of existence of abundant six sigma case studies. To fill this research void, this study proposes a research model testing whether six sigma-based management activities could improve corporate competitiveness. We collected 161 valid questionnaires from participants in six sigma activities, and applied structural equation model. Empirical results showed that six sigma activities could contribute to refreshing process management, quality improvement, and finally corporate competitiveness. We hope that this study would shed a light on the further rigorous studies considering six sigma as a major strategic activity.
