디지털 핑거프린팅(Digital Fingerprinting) 기술은 워터마킹(Watermarking)기술의 한 분야로 콘텐츠에 구매자의 정보를 인지할 수 없는 방법으로 삽입한다는 측면에서 저작권을 위한 판매자의 정보를 삽입하는 워터마킹과 구분된다. 핑거프린팅 기술에서는 주로 구매자의 정보를 삽입하기 때문에 콘텐츠를 처음으로 유포한 구매자를 역 추적할 수 있는 기능(trace traitor)을 제공하는데 본 논문에서는 저작권 보호에 주된 초점이 맞춰져 있는 워터마크 기술을 응용, 핑거프린팅 기법을 사용하여 웹 서버를 통하여 핑거프린팅 기술의 조건을 충족시키는 방법으로 정보를 삽입하여 보여 지는 웹 페이지의 변화없이 판매자가 아닌 구매자(사용자)의 IP정보를 전송할 수 있는 알고리즘을 제안한다.

This study is to develop the web-based English learning courseware and improve the motivational attributes, with systematic methods called the ARCS model of Keller. There are four categories to the ARCS motivation model : Attention, Relevance, Confidence, Satisfaction. Applying these four components to web-based courseware strategically will enable learners to be taught English conversation more effectively and more systematically. In order to implement this study, the main web pages are made of ASP(Active Server Page). Personal Web Server is used as the web sever and Authorware is employed as a courseware authoring tool.

It is not easy for users to effectively have information that is semantically related but scattered on the Web. To obtain qualitatively improved information in web pages, it is necessary to integrate information that is heterogeneous but semantically related. In this study, we propose a method that provides XML-based metadata to users through integration of multiple heterogeneous Web pages. The metadata generated from the proposed system is obtained by integrating different heterogeneous information into a single page, using entity identification based on ontology. A wheelchair information integration system for disabled people is implemented to verify the efficiency of the proposed method. The implemented system provides an integrated web page from multiple web pages as a type of XML document.

Web 기반 시스템 구축시 저렴한 구축비용, 표준화된 문서환경, 클라이언트를 통일하지 않고도 어플리케이션의 구현이 가능한 장점 때문에 인터넷 프로토콜인 TCP/IP와 HTTP를 기반으로 시스템을 구축하려는 기업과 조직이 늘고 있다. 본 논문에서는 web 환경에서 시스템 구축시 적용할 수 잇는 web 기반 시스템 분석/설계 모형을 제안한다. 기존의 web 어플리케이션 개발 방법들이 데이터 분석에 기초를 둔 것과는 달리, 기업과 조직이 가지는 기능을 중심으로 web 어플리케이션을 분석하고, 파악된 기능에서 pageflow를 설계하여 사용자의 요구사항과 조직의 처리가 반영된 page와 네비게이션 경로(navigation path)를 설계할 수 있는 모형을 제시한다.

In this paper, we propose a Web page weighting scheme using the user preference in each sense of query word to improve the performance of Web search. Generally search engines assign weights to a web page by using relevancy only, which is obtained by comparing the query word and the words in a web page. In the information retrieval from huge data such as the Web, simple word comparison cannot distinguish important documents because there exist too many documents with similar relevancy In this paper we implement a WordNet-based user interface that helps to distinguish different senses of query word, and constructed a search engine in which the implicit evaluations by multiple users are reflected in ranking by accumulating the number of clicks. In accumulating click counts, they are stored separately according to senses, so that more accurate search is possible. The experimental results with several keywords show that the precision of proposed system is improved compared to conventional search engines.

The group management system with Wireless Sensor Network and android application is proposed in this paper. The proposed system was composed of personal devices with sensor nodes of WSN, manager device of android platform, and the web server. The sensor node used by each group member send a data packet to the manager device every 2 seconds. The leader device displays and transmits entire information to the web server. The web server represents these information through web page. Therefore, guardians can assure their group member's safety and security on the web page. The RSSI value of each sensor node converted by computed log-normal path loss model into distance value and displays on the manager device and the web page.

In the current Internet environment where there is high space complexity of information, search engines aim to provide accurate information that users want. But content-based method adopted by most of search engines cannot be used as an effective tool in the current Internet environment. As content-based method gives different weights to each web page using morphological characteristics of vocabulary, the method has its drawbacks of not being effective in distinguishing each web page. To resolve this problem and provide useful information to the users, this paper proposes an evaluation method based on categories. Category-based evaluation method is to extend query to semantic relations and measure the similarity to web pages. In applying weighting to web pages, category-based evaluation method utilizes user response to web page retrieval and categories of query and thus better distinguish web pages. The method proposed in this paper has the advantage of being able to effectively provide the information users want through search engines and the utility of category-based evaluation technique has been confirmed through various experiments.

Many search algorithms have been implemented by many researchers on the world wide web. One of the best algorithms is Google using PageRank technology, PageRank approach, computes the number of inlink of each documents then represents documents in order of many inlink. But It is difficult to find the results that user needs. Because this method finds documents not valueable for a person but valueable for public, this paper propose a personalized search engine mixed public with personal worth to solve this problem.

With the amazing growth of web faster important page crawlers poses great challenge. In this research we proposed fractional PageRank, a variation of PageRank computed during crawl that can able to prioritize the downloading order. Experimental results shows that it outperforms the prior crawler in terms of running time yet provide a well download ordering.

In this paper forest fire statistical information management system is constructed on web environment using web based GIS(Geographic Information System) technology. Though this system, general users can easily access forest fire statistical information and obtain them in visual method such as maps, graphs, and text if they have web browsers. Moreover, officials related to forest fire can easily control and manage all information in domestic by accessing input interface, retrieval interface, and out interface. In order to implement this system, IIS 5.0 of Microsoft is used as web server and Oracle 8i and ASP(Active Server Page) are used for database construction and dynamic web page operation, respectively. Also, Arc IMS of ESRI is used to serve map data using Java and HTML as system development language. Through this system, general users can obtain the whole information related to forest fire visually in real time also recognize forest fire prevention. In addition, Forest officials can manage the domestic forest resource and control forest fire dangerous area efficiently and scientifically by analyzing and retrieving huge forest data through this system. So, they can save their manpower, time and cost to collect and manage data.
