기존의 인터넷 검색 편리성을 제공하는 브라우저들은 사용자의 요구에 따라 수동적으로 움직이게 된다. 또한 RSS 와 같은 고급 검색 요구 조건을 만족시키고자 하는 노력에 비하여 사용자의 요구에 따라 능동적으로 움직이기에는 어려움이 존재한다. 이에 본 연구에서는 RSS와 같은 능동적인 정보 검색 및 제공이 가능하고, 표준 HTML2.0을 따르는 효과적인 웹 브라우저인 EasyWeb을 설계 및 구현하고자 한다. 본 논문에서 제안한 EasyWeb 브라우저는 기존의 브라우저들과 달리 표준 규격에 따라 구성하도록 HTML과 XML parsing이 가능하다. 또한 사용자의 요구에 능동적으로 정보를 수집하여 제공할 수 있다. 본 논문에서 제안한 EasyWeb의 구현 결과를 살펴보면 향후 웹 브라우저의 나아갈 방향을 모색할 수 있을 것으로 생각된다.

According to the 2004 Sloan Consortium Report, distance education is the fastest growing sector of higher education. This study suggests a research model, based on an e-Learning success model, the relationship of the e-learner's self-regulated learning strategy, computer self-efficacy, and system quality perception of the e-Learning environment. As a result, perceived usefulness, perceived ease of use, and service quality effect on e-learner's satisfaction. In addition to, self-regulated learning strategy based on computer self-efficacy is also important variable regarding e-learner's satisfaction.

The objective of this study is to identify the relationships among app attribution(perceived usefulness, design, information quality, and mobility), user satisfaction, trust, and continuous use intention of bus information apps; The structural equation of AMOS 21.0 was used to test the hypothesis of this study. The results of the analysis are as follows. First, perceived usefulness, design, information quality, and mobility positively impact user satisfaction. Second, only mobility has a positive effect on trust, but the remaining perceived usefulness, design, and information quality have no effect at the significance level of 5%. Third, user satisfaction has a positive impact on trust and continuous use intention. Fourth, trust has a positive impact on continuous use intention. Therefore, it was confirmed that the characteristics of the bus information mobile app are important influencing factors for the improvement of user satisfaction, trust, and continuous use intention. Local governments and bus companies will be able to establish strategic directions for the activation of bus information mobile apps. The limitation of this study is that it is somewhat lacking in generalizing the study results, so future research needs to focus on improving this part.

IT service is becoming a critical business operation in the age of information revolution. In providing IT services internally to other functions of the corporation and externally to other organizations, sharing of knowledge between business people and system people is known to become more and more critical for successful IT services. Purpose of this research is to examine the impact of IT service quality on knowledge sharing activities between IT service providers and users. Theoretical research model, through an extant literature review, is proposed here, consisting of IT service quality, relationship quality(satisfaction, trust and commitment), and the level of knowledge sharing activities. Survey results of 183 users indicates that IT service quality significantly influences commitment through satisfaction and trust, which in turn influences the level of knowledge sharing activities. Also, interestingly, satisfaction and trust do not directly influences the level of knowledge sharing,but indirectly, through commitment.

The primary purpose of this paper is to identify the influencing factors on the post acceptance behavior of user in internet banking. For this purpose, a research model and hypotheses are developed based on the relevant literature reviews. Data have been collected from 248 users who have used internet banking and the research hypotheses were tested by covariance structural model analysis. The results of this empirical study are summarized as follows. First, security, confirmation, and perceived ease of use have positive influence upon user's perceived usefulness. Second, security, economy efficiency, and confirmation have positive influence upon user's satisfaction. Third, loyalty incentives have positive influence upon continuance intention. Lastly, user's perceived usefulness have positive effect on the satisfaction, and user's perceived usefulness and satisfaction positively related to continuance intention in internet banking. The findings have significant implications for internet banking service providers.

This paper studies the Internet stream server which serves multimedia stream services such as VoD and MoD. The Internet multimedia stream server is developed to provide 50 users with continuous multimedia stream contents simultaneously. This paper focuses on introducing design concepts, operation details and on evaluating system performance and doing sensitivity analysis with respect to the change of the system components. The performance evaluation is performed using simulation in order to identify the system component that mostly affects the system performance. The sensitivity analysis shows the service delay rates of the multimedia stream server depending on the user's service request pattern. Also, the analysis is made on the utilization rates of the core system components such as the PCI bus and the Ethernet card, and on the system performance change by adding more system components.

Multi shopping malls provide us new life-style nowadays with the term, malling. Multi shopping malls are consisted of selling space, entertainment space and convenience space so that arrangement and circulation planning of each facilities have large influence to users. Based on this influences, this study aims to provide basic data for multi shopping malls' circulation planning. Therefore, this study selected 6 multi shopping malls in Seoul and conducted survey that satisfaction of circulation planning of multi shopping malls. For user satisfaction investigation, we studied concept of multi shopping mall following Korean building act and selected composition and characteristics of circulation. Also, we classified the malls to size and circulation shapes for comparison of the satisfaction results. Classified types are high-rise and low-rise and they are separated to small size and big size. In addition, classified circulation shapes are categorized to net type, loop type, cyclical loop type and multi type by forms of central space and main stream of the malls.

Most of large construction companies have developed construction information systems and their ultimate goals should be improvement of the management efficient of the construction projects. In order to make them successful, tile systems should be designed to meet system users' needs. Therefore purpose of this study Is to evaluate the current information management systems from the viewpoint of the system users, especially on-site engineers. Questionnaire surveys and interviews have been conducted for the highly ranked 10 construction companies on two major factors including the functions of the systems and satisfaction level of each function. From the surveys results, correlation between two factors has been statistically analyzed.
