The number of SMEs taking up information systems such as Enterprise Resource Planning has been growing rapidly, and many of those organizations have stepped into the stage of ongoing use at this point. Thus, research which takes into account idiosyncratic nature of SME environment is more important than before. Through an empirical study using survey method, we tried to examine the importance of end user's feedback seeking behavior in SMEs and how environmental factors affecting such behavior reinforce and interact with the feedback seeking behavior itself. The result shows that end user's active role as a voluntary feedback seeker is important in utilizing information systems in accordance with the initial design intention in ongoing use environment. Furthermore, in order to facilitate such feedback seeking behavior in SME environment, it is essential that management's involvement and communicating to its employees the importance of effectively utilizing the information systems as well as the support of peer IT champ.

The purpose of this study is to call attention to the consensus of stakeholders of corporate e-Learning system for the sake of its success. We identified the critical success factors(contents, technical features, management, and organizational support) as major components of corporate e-Learning systems and questioned whether stakeholders' consensus on the importance of these components facilitates the successful implementation of these components. We also questioned whether the influence of these components on user satisfaction could be moderated by contextual factors. Based on empirical testing of 18 e-Learning user companies, we verified that the consensus of stakeholders regarding the importance of content, technological features, and organizational support has a positive influence on the perceived quality of these factors in their e-Learning systems, which in turn is positively related to user satisfaction. The learning subjects and learning style did significantly moderate the influences of these perceived qualities on user satisfaction.

In order to implement the real-time enterprise (RTE) and smart work effectively, many companies have introduced a mobile office. A mobile office improves employee productivity and increases ability to respond to business opportunities by helping employee manage their business anytime and anywhere. However, it also raises the user's stress level. We conducted in-depth interviews with users to assess user's perception of a mobile office according to Saaty's BOCR model. Based on the results of the interviews, we set variables affecting user's perception of the mobile office using factor analysis. This study revealed that support for real-time business, support for communication and collaboration, and information processing quality were positively related to continuous intention to use mobile office. Further study demonstrated that three variables have mediating effect between the psychological stress and continuous intention to use. This result implies that the system quality and function are the key elements of mobile office and may contribute to the continuous use.

This paper aims at developing an integrated fleet management support system for industrial carriers who usually control the vessels of their own or on a time charter to minimize the cost of shipping their cargoes. The work is mainly concerned with the operational management problem of the fleet owned by a major oil company, a typical industrial carrier. The optimal fleet management problem for the major oil company can be divided into two phase problem. The front end corresponds to the production operation problem of the transportation of crude oil, the refinery operation, and the distribution of product oil to comply with the demand of the market. The back end is to tackle the fleet scheduling problem to meet the seaborne transportation demand derived from the front end. Relevant optimization models for each phase are proposed and described briefly. Then a user-friendly integrated fleet management support system is built based on the proposed optimization models for both ends under Windows environment. A case study reflecting the practices of fleet management problem for the major oil company is carried out by using the system.

Objective: The objective of this research is to investigate the fundamentals of human computer interaction for wearable computers and derive technology requirements. Background: A wearable computer can be worn anytime with the support of unrestricted communications and a variety of services which provide maximum capability of information use. Key challenges in developing such wearable computers are the level of comfort that users do not feel what they wear, and easy and intuitive user interface. The research presented in this paper examines user interfaces for wearable computers. Method: In this research, we have classified the wearable user interface technologies and analyzed the advantages and disadvantages from the user's point of view. Based on this analysis, we issued a user interface technology to conduct research and development for commercialization. Results: Technology requirements are drawn to make wearable computers commercialized. Conclusion: The user interface technology for wearable system must start from the understanding of the ergonomic aspects of the end user, because users wear the system on their body. Developers do not try to develop a state-of-the-art technology without the requirement analysis of the end users. If people do not use the technology, it can't survive in the market. Currently, there is no dominant wearable user interface in the world. So, this area might try a new challenge for the technology beyond the traditional interface paradigm through various approaches and attempts. Application: The findings in this study are expected to be used for designing user interface for wearable systems, such as digital clothes and fashion apparel.

The major objective of this paper is to analyze the relationships between End-User Computing(EUC) attributes and its implementation. Reviewing the related literatures, we categorized EUC attributes into threefactors - relative advantage, compatibility, complexity. With such attributes this paper proposed a hypothetical model which explains the effect of the EUC attributes on its implementation. Under the assumption that EUC attributes affect its implementation differently according to the several contingent factors, the model included such factors as organizational size, organizational support level on the EUC activities and individual characteristics - computer experience, education level, age. Data were collected form 177 end-users of 40 Korean business firms. Hypotheses were tested using Pearson Correlation, t-test, ANOVA and the results are discussed below.

This exploratory study addressed the issue of effective EUC management, based on the sociotechnical theory. Extensive literature review gave birth to a set of critical success factors in EUC. With those factors, a basic EUC model was developed. Then the model was tested in the domestic industry to find its validity. It was also attemped to develop a structural equation model in which critical factors for sucessful implementation of EUC are arranged by the result of empirical survey. In the final model, technical support, computer experience, user control, and top management support were included as exogenous factors. Thses contructs were found to influence directly or indirectly three endogenous factors, user satisfaction, computer use, and performance.

인터넷을 중심으로 최근의 네트워크의 발전은 데이터 전송량의 범위를 멀티미디어 정보까지 확대시킴에 따라 멀티미디어 서비스를 보장하기 위해서 기존 인터넷의 Best Effort service에서 제공하지 못하는 end-to-end QoS(Quality of Service)의 제공이 필수적이다. 이를 위해 일정한 수준의 대역폭, 전송지연, 지연변이, 데이터 손실률 등의 network parameter 뿐만 아니라 시스템 내에서도 일정 수준의 CPU time 이나 메모리를 보장해 주어야 한다. 이에 따라 한정된 자원 안에서 멀티미디어 데이터를 분산시켜 네트워크 자원을 효율적으로 관리하기 위해 네트워크 자원 상황에 따라 적절하게 서비스 레벨을 조절하는 QoS 기반 통신 미들웨어의 개발이 시급하다. 또한 네트워크 시스템 및 application 개발자의 입장에서는 이를 구현하기 위해 실제 사용자가 느끼고 평가하게 되는 QoS의 객관적이고 사실적인 측정이 절실히 요구된다. 이를 위해 ATM 망상에서 보다 편리한 QoS 측정장치를 개발하고 또한 이러한 측정기술을 바탕으로 데이터를 추출하여 향상된 QoS를 제공하기 위한 개선된 미들웨어의 실질적인 메커니즘 개발과 검증에 적용한다.
