The new paradigm called the web 2.0 recently appeared in the web environment. We pay attention to the positive effects which may be brought about by application of the web 2.0 to e-learning; we think that it can improve problem solving skills of learners and reinforce their creativity. But until now, e-learning model, which understood the web 2.0 concept completely, has been never developed. In this context, we propose the web 2.0-based e-learning platform which induces all the courses for education such as the selection of topic, preparation of lecture schedule and contents, teaching and learning, to be decided by participants. We believe that this platform can replace or supplement the e-learning of web 1.0 age, and realize the positive effects.

By the most important media to deliver the contents on a remote instruction we commonly use audio and documents. A number of remote instruction system are trying to offer the video, but they did not acquire satisfiable results because of the limited network and width. Also, they use the general web browsers that have a lot of unspecific users access the contents. Also, they use the general web browsers that have a lot of unspecific users access the contents. Like this most systems that use the continuous media have not offer the satisfiable contents because of the network limitation. Moreover, because they use the web browser, they offer the contents having documents(web pages) only. In this paper, we propose a web-based remote instruction system on real-time using audio and documents which are the most important media for a information delivery. In addition to the system, we use a action synchronization mechanism between the web browsers. If the instructor uses web pages on his computer and explains the contents of them, the learners see the same web pages as the instructor's and listens to his voice.

General replacement policy includes document-based LRU or LFU technique and other various replacement policies are used to replace the documents within cache effectively. But, these replacement policies function only with regard to the time and frequency of document request, not considering the popularity of each web site. In this paper, we present the document replacement policies with regard to the popularity of each web site, which are suitable for modern network environments to enhance the hit-ratio and efficiently manage the contents of cache by effectively replacing documents on intermittent requests by new ones.

The purpose of this study is to develop and apply the web contents about the optical characteristics of rock forming minerals. The web contents developed in this study are fundamentally made up so as to show clearly the learning objective and the teaching and learning contents, and to review one content easily and search for another content freely. In addition to the web contents, the photos and moving images of the optical characteristics of rock forming minerals cited in the middle and high school textbooks are demonstrated for the students to recognize the mineral characteristics on the screen. The analysis on the quality level and teaming effect of teaching and teaming materials based on the investigation of the MALSAM after the application of the web contents to the class, showed that most students evaluated were effective for understanding the optical characteristics of the rock-forming minerals. About 62% of the students who used the web contents were able to identify the rock-forming minerals on the thin section under the polarizing microscope.

With development of mobile communications terminal and expansion of mobile Internet, a large number of users can use mobile web contents at anytime and anywhere and will demand service of greater contents. Due to such demand, many studies are being carried out on transcoding contents so that wired web contents can be used in mobile web. However, transcoding and creation of mobile web contents involve difficulties because specifications available from telecommunications companies and mobile terminals have not been standardized. Especially, in order for serving dynamic object of wired web page contents to dynamically change according to time or user, it is required not only to program scripts to suit each terminal, but also to transcode the resources used in advance. For solution to this problem, this study uses the hierarchy structure of DOM (document object model) to display structural characteristics of wired web page. In other words, this study proposes the following technique Wired web pages are analyzed and the results are established as data structure. Then, dynamic object is extracted and the domain is indexed so that, when serving mobile web page, information can be extracted at the indexed position to create mobile web contents for service on real-time basis.

Current web-server deals a multimedia data as well as text data. But dealing a multimedia data is high burden to web-server. So it can degrade web-server response. We introduce H/W feature CDA (Contents Delivery Accelerator). Main function of this H/W is transferring data between SCSI disk and NIC by direct path, and TCP offloading. These 2 functions can accelerate web-server performance. In this paper we will explain problem of current web-server and suggest our new architecture and say various implementation issues.

Recently, it is increasing a users requiring actually and a variety of service due to a growth of wet based technique and network technique. In services, the interest in web and mobile contents domain is increasing rapidly. The most contents supported point or a E-Money as result of contents's usage. But, the point system be in name only due to a lack of a contents using a point or a related service. As a solution for this problem, this paper designed a supported system that integrated a point system supporting others contents and can associated to a game using that point. we made a simple game and supporting contents in web for simulating the designed system. Also, we realized the mobile system for communicating a data causing in web.

In this study, web-sites of home furniture business in Korea have been investigated to understand the conditions for the activation of e-marketing activities. Contents of seven businesses that have been selected for the study was analyzed in three aspects: utility, value of entertainment and structure. Result of the study showed that in the aspect of utility, the web-sites were desired to provide customers with more detail and diverse information rather than simply present description and prices of the products for the purpose of promotion. In the aspect of entertainment value, it was found that the information on the web-sites lacked diversity, originality and expertism, thus requiring for an independent contents development in a way that arouse interest in the web-sites. In the aspect of structure, the web-sites were desired to have interface easy to access and with strong absorption force. To sum up, the examined web-sites were required to diversify their standardized contents in a way that reflects identity of the business and meets diverse needs of customers.

This study was done to analyze the contents of food and nutrition information sites on the internet. In analysis, 276 web sites were used. Web sites from 3 internet search engines(Yahoo, Empas, Naver) were selected on the date of July 15th, 2004. The trained panels evaluated web sites' contents by the assessment tools using 3-point scale(2:strongly agree, 1:agree, 0:disagree). The contents classified by topics were functional foods(46.4%), cuisine and cooking(38.4%), food sanitation and safety(30.4%) and so on. Operators of web sites were individual(35.9%), company(30.4%) and public institution(33.7%). About 89.5% of web sites were operated for unspecified people. Contents of the web sites were well established especially in consistency in title and contents(1.6), scientific basis of explanations(1.2) and benefit of information(1.2) and so on while not well established in providing relevant sites(0.7), providing contact address and feed back mechanism(0.7) and so on. Web sites operated by public institutions are rated significantly higher than web sites operated by individual or company. In conclusion, in order to qualitatively improve food and nutrition information on the internet, continuing monitoring and evaluation are highly required and web sites operated by public institutions shall be developed further.
