A Web-Based Information System(WBIS), a typical structure of recently information systems, should be dynamically restructured in order to satisfy user's need and make a profit. Thus, we should analyze and modelize the navigational structure of WBIS and utilize it by modeling the navigational structure of behavior of user through log-file as system restructuring. In this paper, we propose the modeling method for navigational structure and user behavior to restructure WBIS including shopping mall. Also, we suggest the structural model, state transition model, Petri net model and analysis method and analyze and implement modeling algorithm for user behavior to analyze log-file of it. Then, we propose some restructuring heuristic and apply the methods to the example of WBIS.

This paper is to investigate how types of presenting e-learning contents affect learning. The study examines learning outcome such as students' learning achievement, satisfaction, and perceived learning outcome of a course in liberal arts by three different types: VOD, WBI, and Text. The findings of this study will present the effectiveness of contents presentation type in e-learning. It is anticipated that the study will offer some suggestions to develop e-learning contents types for similar courses and further to develop effective contents types for various courses.

This research was conducted in order to know how influential the acknowledgment of factors such as the quality of educational contents and the conducting of off-line lectures is in terms of effective learning for leaners. Based on the satisfaction-importance model of the multi-attribute attitude model, this study would like to clarify the degree to which the quality of on-line contents of on-line education and the simultaneous conducting of off-line lectures influences one's learning attitude. On-line contents satisfaction will evaluated through the three categories: audio lectures, video lecture and WBI lectures, which make up the quality of on-line contents. We would also like to do a survey on the transformation of learning attitudes when on-line and off-line lectures were conducted simultaneously.

With progress of informationalization, education has been transformed from traditional uni-direction education to bi-directional and consumer-oriented education, which is performed by learner's self study and interactive education of multiple dimension between a learner and contents, between a learner and a teacher, and between a learner and a learner irrespective of space-time. According to this trend, a new education method has been required. Therefore, in this paper, we will propose real-time consumer-oriented distance education system of making interaction maximum using WBI. In this system, a learner can participate in an individual study case by multiple interaction with a learner's designing and plaining study, and also participate in group study case by way of discussion and conversation among participants.

In this paper, we present our prototype of a web manual creator that is based on MSP technology embedded in webMathematica. This tool gives courseware authors more simple ways to make their own mathematical web contents. We first classified authoring models for creating mathematical content development and proposed an advanced model. The final application called phpMath can generate MSP-driven documents automatically using Mathematica commands typed by users. In other words, phpMath users can make interactive dynamic mathematical web contents even though they do not know anything about web server, HTML, and webMathematica. We illustrated the details of the prototype from the user's perspectives followed by comments on usefulness.

e-PBL based on constructivism adopted PBL(Problem Based Learning) and WBI(Web Based Learning), and it becomes the advanced model of instruction to be achieved PBL on-line. In this thesis, I applied e-PBL to 'the changing weather' part in the high school earth science I, compared to the lecture centered instruction, and analyzed how it affected on. On the basis of these, this study predicts the applicability on the cooperative learning and self-directed learning in the high school and suggests the improving of the teaching-learning with the results. The following shows the conclusion with as the central result of research. Firstly, the instruction applied e-PBL proved more effective academic achievement than the lecture centered instruction. Secondly, the instruction applied e-PBL proved more effective on the improving self-directed learning ability. Thirdly, the instruction applied e-PBL proved more effective self-efficacy than the lecture centered instruction.

All learners can selection of their work through hypermedia technology in the area provided by usual WBI. Also, it provides learner with individual teaching-learning environment and estimation. RC2 System has the fundamental client/server model, and provides the learning, evaluation algorithms based on the LCPG(Learning Contents Problem Graph) model, the dynamic re-learning mechanism in according to the property of individual. Moreover, it support learning editor to provide interface, which is convenient for teacher, Courseware writer, on the Web

In middle and high school to learn engineering principles to Experiments in space and time constraints and difficulties for the study of engineering principles to the problem is superficial. In this paper, Pascal's principles etc. learning about fluid mechanics and implemented in Web Browser, In connection with flash and HTML, and simulation and virtual experiments is to implement interesting. Of fluid mechanics education through engineering design and web design through the actual web server is implemented on the Internet over broadband. Department of Education, this study fluid dynamics and the Internet will contribute to the development of distance education.

A lot of problems with information education may be obstacles to the sound development of the information society, but they can't stop this social change. As the social environment has changed, our viewpoint and teaching methods have been changed. The techniques of the network are the force of this information society, and personal education is needed for a sound future. We should think about the problems and side effects of these changes and work out the teaching and learning methods which are most suitable for our current society. We need to be quick to discover ways to remove the problems of the information society. In this paper, we develop courseware for network etiquette and apply them to the education curriculum.

Internet becomes absolutely necessary tools due to rapid progress of information technology. Educational correspondence abount an age of information demand is a education focused on a learner and remote education based on information technology. Internal and external standardization working is accelerated and recently XML security studies are activated using XML which is next generation web standard document format. But using these are main contents that users have to pay about Certification service to get CA certificate from 2004 me. This paper propose multiplex Certification remote education agent system using XML digital signature to satisfy security requirement.
