The University's web library is a form of library that enables to deal with information about searching loaning, returning of books or data housed in it through web. With the advent of the network and multimedia following the entrance to an information-oriented society, we are experiencing a big change in how to communicate and acquire information. Massive multimedia information transmitted by image and moving picture through the network, made it possible to overstep the limit of the physical gap between information suppliers and users. Despite this important role, it is accompanied by problems such as copyright, scarcity of recognition, paralysis of infra, technical matters and reliability which demand development. In this thesis, according to the State University Evaluation Standards, search node and user interface by system used in 20 different universities possessing web-based library sites were compared are analysed. On the basis of this, an experimental user interface for web-based University libraries was produced, and various questionnaires and data leer this produced interface were collected, classified and analyzed. With the application of the results for the work above to the general search system interface of the web-based library, we proposed a new user interface that contains the following functions, such as location and loan condition of books, search frequency and steps for purchasing books inside the web library.

This study could begin with the improvement of computer graphic technology The graphic technology is the standards of computer technology level and up-to-date technology intensive. Above all, the technology of virtual reality has developed rapidly and the development of the program has changed from professional one only for the experts to easy of access ones for the space designers. Moreover, the program which major internet user's can experience the virtual model has been made, as the development of virtual reality technology that is based on the web. These graphic technology and the development of the web helped to extract human experiences on the space design step. However, to find the meeting point with real recognition is not easy though the virtual reality technology develops. Because the real space is made up of various senses that people feel in their surroundings. But, this study was possible because most of the space recognition is based on the visual organ, even though it can't satisfy all sensible factors that we feel in reality. Therefore, the significant of this study is the standards and criteria of evaluation, the technological proposal, expecting to make more advanced alternative design than before.

Purpose: This study was conducted to develop and evaluate a Web-based program for the maternal role of primiparas who use the internet. Method: The study process was a systems requirements analysis, design and development of a program, program testing by experts, program implementation, and program evaluation by users. A nonequivalent control group non-synchronized design was used. The data was collected from October 5th, 2002 to February 24th, 2003. Result: 1. Based on inquiries into mothers' needs, a Web-based support program was developed. The program was then modified from feedback received from experts. 2. In a sub-scale analysis of mothers' perception of a baby, amenability and persistence was significantly higher in the intervention group. The differences in the mean score of maternal self-confidence and maternal satisfaction were significant. 3. Cyber counseling was done for a total of 73 cases and the most frequent problems for counseling were feeding and nutrition (28.8%), followed by baby care, and health problems. Conclusion: It was proven that a Web-based support program provided appropriate support to primiparas and was effective in promoting their maternal role. Therefore, this study suggests that a Web-based support program for primiparas can become a powerful nursing intervention on virtually all mother and infant health concerns.

This study describes the development of nursing education program on web-based instruction for Nursing Management Practice of nursing school. The program has been developed based on five steps of the teaching-learning design model developed by Chung, In-Sung which is widely used in Web-Based Instruction(WBI). The objective of this study was to develop nursing education program on WEI and to evaluate its effectiveness. The subjects consisted of twenty-four senior nursing students taking the Nursing Management Practice course. Two sets of questionnaires were used for this study. They were asked to evaluate the program in terms of appropriateness of the teaching strategy, precision of the contents, easiness of use, easiness of approaching system, interface design, system management, enhancement of communication, and effectiveness of learning. The program was developed in five steps, analysis of the student, design of the contents, production of the system, implementation of the system, and evaluation of the effectiveness. It is concluded that this program was very useful in increasing the effectiveness of learning and motivation in the students. In addition to this, the web-based learning system would be one of the best qualified educational method for nursing students. Therefore, I would suggest that it can be used for other nursing courses which is available on the Web.

The purpose of this study is to empirically investigate critical success factors for effective implementation of web-based distance learning system. First of all, four critical success factors are theoretically derived from reviewing previous research. They are: (1) learner-related factor including the variables such as teaming ability, learning attitude, and attending motivation, (2) environmental factor including the variables of physical and mental support for learners, (3) instructional design factor represented by one variable, the degree of appropriateness of learning contents, and (4) the factor concerning the level of self-directed learning readiness embracing the variables such as curiosity for learning, openness towards challenge of learning and affection for learning. Subsequently, the relationships between these four critical success factors and the degree of learning satisfaction are empirically investigated. The data for empirical analysis of the research are collected from 1,020 respondents who have already passed the web-based distance learning courses which have been implemented in Information and Communication Officials Training Institute. Out of 1,020 responded questionnaires, 875 data were available for statistical analyses. The main results of this study are as follows. Firstly, the most important factor for successful implementation of the web-based distance learning system is shown to be the instructional design factor, and in the next place, the self-directed learning readiness factor, the environmental factor and the learner-related one in sequence. Secondly, additional analysis of the variables included in the instructional design factor shows that availability of practical information and knowledge is the most influencing variable, and next, interesting composition of contents, reasonable learning amount, optimal level of instruction, and understandable explanation are significantly important in the descending order. Lastly, among learning motivators, strong intention of acquiring business knowledges and skills is found to be the most important satisfier in the web-based distance learning. The theoretical contribution of this study is to derive a comprehensive model of critical success factors for implementing the web-based distance learning system. And, the practical implication of this study is to propose efficient and effective guidelines for developing and operating the web-based distance learning system in the various kinds of organizations.

In order to realize the virtual prototyping (VP) of digital products, it is important to provide the people involved in product development with the appropriate visualization and interaction of the products, and the vivid simulation of user interface (UI) behaviors in an interactive 3D virtual environment. In this paper, we propose an approach to web-based 3D virtual experience using Unity and Leap Motion. We adopt Unity as an implementation platform which easily and rapidly implements the visualization of the products and the design and simulation of their UI behaviors, and allows remote users to get an easy access to the virtual environment. Additionally, we combine Leap Motion with Unity to embody natural and immersive interaction using the user's hand gesture. Based on the proposed approach, we have developed a testbed system for web-based 3D virtual experience and applied it for the design evaluation of various digital products. Button selection test was done to investigate the quality of the interaction using Leap Motion, and a preliminary user study was also performed to show the usefulness of the proposed approach.

As web-based programming tools(such as flash action script, javascript, java and etc.) has been improved and it has become more aware to take interactivity importantly as users' whole experience, web sites have evolved from the form of webzine to the form of interactive application that displays more interactive interface and gives instant feedbacks for the users' inputs. Web, rather than software, is used to execute relatively easy tasks by users of various levels, so that web sites could give more fun and less cognitive burden by supporting users' tasks in more interactive way. This paper examined design strategies to make more interactive web by figuring out definition of web interaction as users' experience and by analyzing web interaction design trends from cases of interactive web sites. The ultimate objective of this paper is show how design strategies can be adapted in the web interaction design process. Thus, case study of designing interactive bookshell in E-book site was done and is demonstrating one way of adapting strategies to design web interaction.
