Facing competitive and complicated business environment, many companies are developing new and diverse organization forms not only to overcome to minimize costs and risks but also to maximize the efficiency of an organization. Virtual organization is one of the representative forms allowing firms to create this value though a link of core competency among firms. In order to explain the performance of virtual organization in terms of efficiency, this study utilizes a concept of trust since it is recently considered as one of core concept to enhance the cooperative performance between firms and also virtual organizations success or failure can not be properly explained by traditional transaction-cost based economic point of view. Based on previous literature this study derives three success factors, organizational reputation, skill Uniqueness, and interpersonal trust and studies how three factors influence on the efficiency of virtual organization. Findings conducted with a questionnaire survey are as follow: first, organization reputation and skill uniqueness between virtual organization's transaction parties are important elements in the success of virtual organization. Second, interpersonal trust affected by organization reputation and skill uniqueness decides virtual organization's efficiency.

Recently, many organizations in various industries have introduced e-business for the purpose of adding value to their business. But, the e-business model has not existed before and so, it is difficult to analyze clear effectiveness. It frequently does not live up to an organization's expectations. It is due to an absence of environmental changes analysis in the new model, not by a new model itself. System Dynamics(SD) may provide effective results as a tool of analysis for the new model. This research shows the analysis of the effects of a simulated e channel model, which was expanded from existing channel modeling with actual data in basic materials industries. The results show average prices increasing by auction process on the e-market and an increase in sales. So, by increasing the speed of sale revolution stock expenses are reduced. Additionally, we applied a possible scenario to the developed simulation model and investigated strategic issues to draw desirable strategies with market changes.

This study investigated the current status and characteristics of strategic alliances attempted by domestic internet businesses. Specifically, this study surveyed competitive environmental characteristics of partner companies involved, alliance period, types of partner companies, motives of alliances, types of alliances, success and failure factors and satisfaction toward the alliances. Major findings were: first, alliances between portal companies and content producers; portal companies and internet services; e-commercial sites and internet services were the most frequent partnerships engaged. Second, the most important motive for and type of the strategic alliance were: 'the commercialization and marketing of new product' and 'joint distribution and marketing agreement' respectively. Third, the most important factor for the successful alliance was 'a close examination of partners' core business value and competence'; and the factor most hindering the successful alliance was 'a discrepancy on capabilities of partners' core personnel. Finally types of internet business were significantly related to perceived satisfaction toward strategic alliance.

Business process redesign(BPR) has been widely adopted as an organizational change method since 1990s as the competitive pressures have forced organizations to constantly change. Although BPR has provided successful stories to gain dramatic improvement in performance and has been promoted as an enabler of organizational change, many organizations have faced serious challenges with widely mixed results due to the lack of understanding for potential organizational conflicts and the improper targeting of critical processes in the initial stage of BPR. This paper proposes a cognitive map based method to help organizational members identify potential organizational conflicts, capture core business activities, and suggests guidelines to lead to the necessary organizational change. A computerized tool has been developed to support the real world cases. Working procedure of the proposed method is illustrated with its application to the real BPR project of a dairy company.

Recently, firms which have offered a "free Internet service" to their customers, are considering a "charged Internet service" for increasing a company's profit. But they have doubts about the results, because consumers may fly away from their web-site easily and may discontinue using their services. The purpose of this study is to investigate which factors make consumers use the charged Internet services. To do this, the factors, which are ease of using the service, usefulness of the service, the reputation of the service provider, service cost, and the intention to use the service as a mediator, are analyzed. To achieve this research objective, a structural equation model was constructed and a field study method was used. The findings are summarized as follows: First, ease of using the service, usefulness of the service, and service cost have significant impacts on the charged Internet service usage through the intention to use. Especially, although service cost influences on the service usage largely, the usefulness of the service has a bigger impact on the charged Internet service usage than service cost. Second, the reputation of the service provider does not have any impact on the service usage. Third, consumers using only the free Internet service tend to hesitate about using the "charged Internet service" because they doubt its ease of use and usefulness in spite of the service cost.

This paper aims to investigate the adjustment effect of switching barriers on customer retention in mobile telecommunication services. The detailed factors regarding switching barriers are classified based on the related literatures. Furthermore, the hierarchical regression analysis is used to analyze the extent to which the factors affect customer retention. The main contribution of this paper is to focus on switching barriers and theirs relationships with customer retention rather than customer satisfaction on early studies. The results are as follows: First, among the factors of switching barriers, switching costs, such as continuity cost and contractual cost, interpersonal relationship, and attractiveness of alternatives are key factors in determining customer retention. Second, continuity cost and interpersonal relationship have an adjustment effect between customer satisfaction and customer retention. The findings can help the mobile operators establish a customer-oriented strategy by identifying a few key factors strengthening the linkage with customers.

This paper examines internet shopping mall user's customer satisfaction and their consequent attitude and customer loyalty behaviors. For this purpose, internet shopping mall user's customer satisfaction is proposed to affect trust, and commitment, and consequently to influence customer loyalty behaviors. This study, which used data from customers of internet shopping malls, showed satisfactory data-fit of the proposed model and supported five of the six research hypotheses. The empirical results indicated that customer satisfaction take significant effect on trust, and commitment, and the trust and commitment in turn have strong influence on customer's loyalty behaviors. It was confirmed that both trust and commitment variables are effective mediators linking internet shopping mall user's customer satisfaction and their loyalty behaviors.

The purpose of this research is, first, to assess empirically web3D impacts on consumer information processing. Second, this research aimed to reveal the circumstances under which web3D impact can be maximized. To achieve the second goal, products were classified into physical dominant and information dominant products, and web3D impact was assessed on these two product categories. The laboratory experiment was adopted to compare the web3D impacts on the physical dominant products with that on the information dominant products. The result of this experiment showed that overall, web3D positively influenced consumer comprehension, memory, and attitude toward the products. In detail, for the physical dominant products, subjects significantly comprehended and memorized information better and performed positive attitude toward the products. For the information dominant products, subjects significantly comprehended and memorized better but did not perform the positive attitude toward the products. This paper explains theses results by suggesting that, overall, web3D impact is large and can be maximized when the characteristics of web3D such as interactivity, realistic display of objects support the characteristics of products that web3D represents.

As the interest in the business-to-business(B2B) electronic commerce is increasing, some companies are participating in the B2B eMarketplaces(electronic marketplaces). The eMarketplace has an effect on the method of B2B transactions or the purchasing performance. The academy and the industry are focused on the cause and the result of this effect. The purpose of this research is to analyze the effects of the relational exchange with eMarketplace on the purchasing performance, considering the supply externality and system integration as intervening variables. This study investigates the second-order effect of eMarketplace in which the degree of improvements in two aspects of purchasing activity(price reduction, purchasing efficiency) depends on the degree of the relational exchange with eMarketplace, namely, the governance of eMarketplace. Our hypotheses on this second order effect were supported. We found that the higher the relational governance, the lower in price reduction, and the better in purchasing efficiency. In more details, the high relational governance lowers the supply externality, and in turn deteriorates the improvement in price reduction. Meanwhile, the high relational governance accelerates the information system integration, and brings the better purchasing efficiency. Our findings suggest that organizations can improve their purchasing activities better if they choose the appropriate eMarketplace governance.

The technology acceptance model(TAM) has been widely studied in IS research in order to gain a better understanding of the adoption and use of information systems. Based on the TAM, we explored acceptance of internet shopping mall. 261 questionaries were collected and analyzed. The results of this study showed that the internet shopping mall characteristics such as information quality, system design quality, and communication are important factors in affecting user's visiting and buying frequency at the internet shopping mall. Therefore, the internet shopping mall providers should make the product's information more informative and design shopping mall sites more effectively and interactively.

This paper employs the lens of the resource-based view(RBV) to investigate how firms create competitive advantages through IS outsourcing arrangements. The RBV framework is used to explore how a firm adds value and reaps benefits from IS outsourcing arrangements. The primary finding is that in the process of value creation, the 'absorption' of the managerial and technical capabilities of external vendors is critical. When the client firm is able to absorb and integrate the IT capabilities of outsourcing vendors, these absorbed capabilities in turn become the source of IT competence and competitive advantages $vis-\grave{a}-vis$ the competition.

Many R&D organizations have interests on knowledge management system(KMS) to organize and utilize their knowledge resources. Currently, for research collaboration and knowledge management R&D organizations use either a specialized knowledge management system or a set of general application systems such as basic messaging system and document management system. The objectives of this paper are to identify important functionalities of knowledge management systems based on team characteristics and knowledge process of research teams in research organizations and to provide implications to design and implement knowledge management system for R&D teams. Survey results show that research teams perceive communication, collaboration and connection functionalities are important when their team sizes are large or they are distributed. During knowledge capture process, they need personalization of knowledge to reduce information overload.
