Despite the increasing pervasiveness of electronic commerce, very little empirical research has been done to examine its use in organizational contexts. Based on theories from the technological innovation literature, we developed an integrated model of electronic commerce initiation, adoption and implementation in Korea. We selected a random sample of 500 Korean leading companies. A questionnaire survey examined factors in initiation, adoption, and implementation of electronic commerce. Independent variables of this research were environment uncertainty, organizational characteristics(namely, organizational size, centralization, and formalization), and information system maturity. The resultant study sample included 62 firms across the industries. The empirical tests of the hypotheses were performed. According to our findings, environmental uncertainty, centralization, formalization, and information system maturity have a significant effect on the electronic commerce initiation, adoption and implementation.

Recently implementing enterprise resource planning (ERP) systems with packaged business software is growing rapidly. The purpose of this article is to provide further insights into the business process change and change management in implementation process of ERP systems. This paper examine an survey of some 146 firms' adoption and implementation of packaged ERP software. In this paper, we propose an integrated approach of business process change and change management of the implementation process. This research highlights the importance of change management for implementing ERP. In addition, we empirically reveals that the eventual success of ERP systems depends on effective business process change and change management during the ERP implementation.

The objective of this research project is empirically investigating factors influencing EPP system implementation based on the degree of volatility of business environment. The results show that computes with low volatility have successfully implement ERP system compared to companies with high volatility. This research project also identified success factors of each phased chartering phase, executive participation sound assessment of business condition, good understanding of ERP system and carefully constructed case are identified as success factors. During project expenditures, participation of various groups, technical resources, prefect and change management are found to be important for successful construction. Trained users, integration of systems, well-designed process and technical and human resource are found to be success factors during shakedown phase. Managers commitment technical infrastructure, system flexibility, and adequate resource for maintenance and renewing system are identified as success factors of onward and upward phase.

Critical success factors (CSFs) have been replicated and applied in a wide variety of settings for more than two decades. Most previous research on CSF have focused on identifying critical factors, based on the variance theory, in terms of the correlation between individual factor and Information system (IS) success. However, it is unknown how a set of critical factors Influence each other and lead to IS success, which means the process of IS implementation. in this research, we aim to understand how a set of critical factors influence each other and lead to IS success in the context of IS implementation for Customer Relationship Management based on the process theory. This research has implications In explaining a mechanism leading to CRM systems success based on the influencial relationships among the critical factors.

The purpose of this study is to introduce the implementation of WML and WMLScript by using the Openwave WAP simulator. For this purpose, previous literature review was done on the studies about the structures of WAP systems, types of WAP Browsers, and development methods of WAP contents. Afterwards, I attempt to implement WML and WMLScript by using an openwave Phone simulator, openwave WAP simulator, openwave HTTP simulator and Nokia Mobile Internet Toolkit. Few studies have been completed on implementation of WMLScript and it's complex process. Therefore, this study explores the necessary implementation steps and develops an easier way to create and experiment mobile applications using WMLScript.

In this paper, we set up an implementation plan for the Mail Acceptance System (MAS) to be operated more effectively and intelligently. First of all, an as-is analysis for the current MAS is performed for analyzing issues and problems and obtaining user requirements. After the as-is analysis, we perform benchmarking studies on the various postal service providers of the advanced countries. Based on the results from the as-is analysis and benchmarking study, we design a conceptual model for the future MAS. The proposed conceptual model can be classified into three parts: automatic MAS, business MAS, and integrated MAS. Information and automation technologies are applied to design the proposed model for eliminating inefficiencies and inaccuracies in MAS. We identify implementation tasks for realizing the proposed MAS model, evaluate the importance and precedence relationship of the identified tasks for deciding implementation priorities, and finally set up the implementation plan for the future MAS. We can expect that the more efficient and effective MAS can be constructed in the future by performing the proposed implementation plan.

We presents a source module implementation system using building blocks as one of the software reusing approach. Based on module text retrieval system, system is composed of library management program and new module making program for module management. We build a software module by virtue of the reuser's customization and by applying a practical module to this model and then proved that program development through reusing approach is better than that of writing out a source code directly.

KORMARC used in library bibliographic information, had been pointed several weaknesses such as inflexibility lack of link information and compatibility. In addition, a sudden increase in digital information associated with development of internet is demanding an integration of web resources metadata as the resource of library information. This study mentioned XML/KORMARC system or adaption of XML standard format turned out to be the most efficient way to use KORMARC formats and to expand the range of those information service such as bibliographic information, factual information, referral information and full-text.

Electronic Data Interchange (EDI) is an important part of interorganizational electronic commerce due to the strategic impact derived from its use. In order to ensure successful implementation of EDI, EDI controls must first be developed. Because they are implemented in an environmental context, the characteristics of organizational environments have a significant impact on EDI controls. The control strategy for the EDI system - formal, informal, and automated controls - should fit certain organizational environments. A research model has been developed to depict the moderating effects of six environmental variables including industry, organizational, and task characteristics on the relationships between controls and implementation. It is shown empirically that the relationships between EDI controls and implementation are indeed affected by these factors. The results can help management design formal, informal, and automated controls in view of their own environmental contexts.

This paper describes the design and implementation techniques of a generic Internet-based telerobotic system. The purpose is to make available the precious technical information and hands-on experience of the authors for the research community. The paper is based on the telerobotics system that the authors recently implemented between KAIST, Korea and Saga University, Japan. In its current functionality, two control modes: high-level supervisory control and low-level supervisory control are explored demonstrating their merits and demerits.
