As the number of Web reference resources are gradually increasing, reference librarians have to create a Web-based reference resources site. This site includes links to the Web reference resources of good quality, so that reference librarians and users will become accustomed to using these resources. This Study first explores the function of the Web-based reference resources site. Next, it carries out a survey of the current trends in america and Korea. Finally, a model Web-based reference resources site for academic libraries is developed.

Generally we use web cache in order to increase performance of web base system, and a replacement technique has a great influence on performance of web cache. A web cache replacement technique is different from a replacement technique of memory scope, and a unit substituted for is web object Also, as for the web object, a variation of user reference characteristics is very great. Therefore, a web cache replacement technique can reflect enough characteristics of this web object. But the existing web caching techniques were not able to reflect enough these object reference characteristics. A principal viewpoint of this study is reference characteristic analysis, an elevation of an object hit rate, an improvement of response time. First of all we analyzed a reference characteristics of an web object by log analysis. And we divide web cache storage scope using the result of reference characteristics analysis. In the experiment result, we can confirm that performance of an object-hit ratio and a response speed was improved than a conventional technique about a proposal technique.

We proposed a Web cache replacement technique of a divided scope base that considered a size reference characteristics of a Web object for efficient operation of a Web base system and, in this study, analyzed performance of the replacement technique that proposed it though an experiment. We analyzed a reference characteristics of size to occur by a user reference characteristics through log analysis of a Web Base system in an experiment. And we divide storage scope of a cache server as its analysis result and tested this replacement technique based n divided scope. The proposed technique has a flexibility about a change of a reference characteristics of a user. Also, experiment result, we compared it with LRU and the LRUMIN which were an existing replacement technique and confirmed an elevation of an object hit ratio.

Generally, a study of web caching is conducted on a performance improvement with structural approaches and a new hybrid method using existing methods, and studies on caching method itself. And existing analysis of reference-characteristic are conducted on a history analysis and a preference of users, a view point of data mining by log analysis. In this study, we analyze the reference-characteristic of web object on a view point of a characteristic of probability-distribution and a mean value of lifetime of a web-object. And using this result, we propose the new method for a performance improvement of a web-caching.

It has been important of a web programming education with the rapid development of the internet. The learning system for the web programming education needs that develops web programming and can check the results on the web. In this paper. I suggested the learning system that can confirm the editable script result on the web client-side languages as well as server-side languages. The reference scripts that refer the web elements to study the web language make a database with an hierarchical structure. The reference script database enhances the utility of the script as managing the database system. The reference scripts can verify the results with the editable state that the structure of the web documents is altered and the elements, attributes, attributes's values of web languages is changed. The reference script tests can ascertain the adaption of it with the frame test and the window test.

The unit of the digital content delivery is the web object. For the improvement of the content delivery based on the web, it id required analysis of reference characteristics of the web object. In this study, we analyze reference characteristics of the web object and evaluate the performance. Using these analysis results, we propose the digital content delivery system which is improved delivery efficiency. The goal of the proposed system are the improvement of the processing time through enhancement of the caching efficiency with reflect reference characteristics of the web object. And the experiment result, we verify the performance enhancement.

In this study, system of opening of archival documents and providing reference services and archives web service in China have been reviewed. Throughout laws and regulations of archives management since found the People's Republic of China, related to opening of archival documents and providing reference services are analyzed. This paper also consider the present condition of archives web service in China and web service of Beijing archives.

The Web site which many people manage and maintenance much HTML page is so difficult to solve broken link like as dangling reference and inaccurate contents reference. That is, in the case we update or delete connections structure between HTML documents, it is difficult to guarantee referential integrity of Web Pages. In this chapter, we surveyed and defined integrity constraints condition between the parent page and child page, and studied about method to express by extension UML. WWW, Constraints, UML

Many libraries and information centers offer various resources on their web sites and web reference is one of them. However, it can be quite burdensome for individual libraries to build a reliable database while sorting through countless web data. The attempts to build a collaborative database have been also unsuccessful due to heavy workload of librarians and financing problems. This study seeks to propose a UCC(User Created Contents)-based web reference database created by general users including librarians. It is an open reference database where everyone can contribute regardless of their affiliation and library types (for librarians), Also, it requires metadata scheme to standardize web-based references. By setting the initial metadata, it can present a basic guideline for users to post web references.
