In Web Based Instruction, as evaluation of learning process means individual student's learning activity, it demands data on learning time, pattern, participation, environment in a specific learning contents. The purpose of this paper is to reflect analysis results of individual student's learning status in achievement evaluation using the most suitable web log mining to settle evaluation problem of learning process, an issue in web based instruction. The contents and results of this study are as following. First, conformity item for learning status analysis is determined and web log data preprocessing is executed. Second, on the basis of web log data, I construct student's database and analyze learning status using data mining techniques.

Most recent web search engines perform effective keyword-based multimedia contents retrieval by investigating keywords associated with multimedia contents on the Web and comparing them with query keywords. On the other hand, most music and compilation albums provide professional artwork as cover art that will be displayed when the music is played. If the cover art is not available, then the music player just displays some dummy or random images, but this has been a source of dissatisfaction. In this paper, in order to automatically create cover art that is matched with music contents, we propose a music album cover art creation scheme based on music contents analysis and result synthesis. We first (i) analyze music contents and their lyrics and extract representative keywords, (ii) expand the keywords using WordNet and generate various queries, (iii) retrieve related images from the Web using those queries, and finally (iv) synthesize them according to the user preference for album cover art. To show the effectiveness of our scheme, we developed a prototype system and reported some results.

The purpose of this study is to analyze systematically the characteristics and types of contemporary houses and to offer information concerning houses based on web database. This study deals with single-unit Korean houses designed by modern architects, which appeared in architectural periodicals and books published since 1990. This study sets three analysis criteria : general characteristics, morphological characteristics and functional characteristics of houses. Also, the web database including analysis contents is constructed to attain various information of the houses and results. The process of constructing the web database and the search method for house information retrieval are described. It is concluded that contemporary houses show various aspects of their plans in certain specific types. By using web database we obtained various analysis on house plan. This study investigated practicality of web database in architecture, interior design and house studies, and the types of contemporary house plans are revealed as well.

In this study 3D topographic modeling was made by using aerial photography and digital terrain map, through this we did visibility analysis and implemented Web GIS of Dong-A university. Studying area was Busan Saha-gu Hadan-dong, we used aerial photography on a scale of 1:20,000 and digital terrain map on a scale of 1:5,000. Ortho correction image was made by aerial photography through selecting GCP, image matching, image resampling and precise differential rectification. And DEM on digital map was created using ArcView program, making 3D topographic modeling by road layer and building layer and implementing Web GIS about Dong-A university.

Recently, common users are familiar with the various dynamic displays and interfaces owing to the developments of web browser and Flash. As Flash also has become popular, it has attracted more application of many users, which nowadays makes them focus on the unique characteristics of web - the interactive and dynamic design. Therefore, this dissertation performs the type-analysis of the layouts and the understanding of the actual condition for the existing interactive-sites, followed by the considering of the design-related methodology and the utility of Flash program.

현재 인터넷상에서 서비스되고 있는 컨텐츠는 업그레이드되어 3차원 가상기법인 Web 3D 기술을 적용한 사실적이며 현실감 있는 환경에서 상호작용이 가능한 컨텐츠로 전환되고 있다. 이에 Web 3D의 시장에 많은 저작도구들이 개발되고 활용되고 있다. VRML를 기반으로 하는 표준 기술과 특정분야에 활용될 수 있게 개발된 비표준 기술들로 발전하고 있는 환경에서 Web 3D 컨텐츠 구축을 위한 저작도구의 분석은 필연적이라 생각된다. Web 3D 저작도구의 기본 기능과 확장성, 호환성, 적용분야를 비교 분석하여 각 활용분야와 체형에 맞는 저작도구의 선택을 통한 컨텐츠 제작 효율의 극대화를 제안한다.

Currently, obtaining information about the interior design studies through the internet web sites is one of the outstanding mediums. Those are of the housings, architecture, interior design, furniture products, hotels and its journals, etc., and out of all those informations are the highly expected value of use. This study focuses on web-site uses in the interior designs' business. To process the study, a two-step research was executed; The step 1 was to find out the current status of web-sites by asking the each panelist to submit the monitored results after having searched and tested for more than two sites that was executed during the October, 2001. The analysis was made with the 47 sample sites selected from the monitored sites. And the step 2 was to find out the contents and evaluation factors of web-sites related the interior design. The results of the study are summarized as follows: First, the monitored Intoner design related 25 web-sites were classified into 3 groups. One group of 13 sites is identified as a remodeling/construction works, and one another with 7 sites is as shopping site, and the other with 5 sites is as a professional portal site. Second, the evaluation has been implemented which has shown 5 variables on the information searches are $\circled1$ the diversities of contents, $\circled2$ the accuracy/reliability of techniques, $\circled3$ the design of a picture and communication, $\circled4$ the convenience of link, and $\circled5$ the originality of web-site This study will provide the users with a fundamental material in evaluating the quality of interior design information on the internet web sites.

Web Applications are rapidly increasing and the structure becomes very complicated. However, when users explore such complex Web applications, they cannot often grasp the current location and get the information that they want. Therefore, a novel approach to model the navigation of Web application contents is required. In this study, a framework has been presented for modeling adaptive context-based contents navigation of Web applications. The framework performs activities including navigation analysis, navigation design, and navigation realization. first, in navigation analysis domain is analyzed by using use case, focusing on navigation. Next, in navigation design three models have been produced: a navigation information model, a profile, and a navigation interface model. Finally, in navigation realization a Webpage navigation model and a component navigation model have been produced. In this work, several formal definitions and rules for checking validity of navigation model have also been provided.

Web-services have originally been devised to share information as open services. In connection with it, hacking incidents have surged. Currently, Web-log analysis plays a crucial clue role in detecting Web-hacking. A growing number of cases are really related to perceiving and improving the weakness of Web-services based on Web-log analysis. Such as this, Web-log analysis plays a central role in finding out problems that Web has. Hence, Our research thesis suggests Web-DoS-hacking detective technique In the process of detecting such problems through SOM algorithm, the emergence frequency of BMU(Best Matching Unit) was studied, assuming the unit with the highest emergence frequency, as abnormal, and the problem- detection technique was recommended through the comparison of what's called BMU as input data.
