Recently, the Web 2.0 and RSS techniques have gained enormous attention in the Internet and e-Learning fields. In this paper, we design a RSS system on the Web 2,0 base for e-Learning, and implement the educational RSS information sharing system for back-to-basic curriculum of secondary schools that is called EduRSS. Our EduRSS can create web feed file with RSS format from learning blogs for back-to-basic curriculum, and share it with other users conveniently. In addition, it also provide the recommendation function to improve the reliability of the RSS feed resources.

Due to the recent tremendous growth of internet information, RSS, syndication technology provides internet users with a user-friendly information search. RSS enables you to automatically receive newly updated contents, so users do not need to constantly access web sites to obtain new information. This paper proposes the way of managing the web crawler, which collects the sites of RSS documents and helps the users efficiently use the RSS documents. And it also suggests the proper way of ranking the RSS documents based on the users' popularity. Users can efficiently search out the documents they need by using the proposed information searching methods.

Recently, the most of website is supporting RSS with increasing the interest regarding web 2.0. RSS-reader is collecting the contents of RSS formats which are provided from the various web site and it is software application that assist users easily to getting the last update of area of interest without visiting a corresponding web site. In this paper, we developed RSS reader through Ajax which is an asynchronous method, JSP/Servlet which is a dynamic scripting language. We made them support both RSS format 1.0 and 2.0. Additionally developed fluid Ajax based menus, categories and functions of user-friendliness.

Research on RSS(Really Simple Syndication) based application and services are being deployed both domestically and internationally. The RSS service in the area of science and technology should be flexible to the various sources of information as well as the various platform and environments that they are being serviced. It also requires a standardized system to meet the above needs. We have analyzed the use of RSS services overseas as well as domestic services to suggest the implementation of standard system for the syndication of science and technology information based on RSS.

RSS is a core component of Web 2.0 which is expected to lead the most important innovation in the new IT environment. In that sense, it is actively utilized to distribute Web contents in various areas such as news, blog, multimedia, medical information, and conference and journal information. Also, it is expected to be a major effective marketing tool in electronic commerce domain. In the paper, we analyzed the problems of current utilization of RSS in domestic shopping malls, and suggest requirements for the effective use of RSS in electronic commerce. Furthermore, we proposed various issues and answers on the implementation of the requirements, and designed the intelligent RSS framework for electronic commerce based on the issues. Syntactic and semantic interoperability between the RSS service provider and the user is one of the most important issues in the framework. We suggested how to implement the interoperability based on Semantic Web technologies.

In this thesis, we propose the test statistic for ordered alternatives on c-sample ranked set samples(RSS). The proposed test statistic JRSS is Jonckheere type statistic using the median of the i-th samples in each cycle. We obtained the asymptotic property of the proposed test statistic and the asymptotic relative efficiencies of the proposed test statistic with respect to J SRS which Jonckheere type statistic on simple random samples(SRS). From the simulation works, J RSS is superior to J SRS. We compared the empirical powers of J RSS with respect to U RSS on ranked set sample and U SRS on simple random sample using all samples, which are proposed by Kim, Kim and Lee(1999). The powers of J RSS are nearly the same values when entire sample size is large. J RSS is superior to U RSS. J RSS is simpler than U RSSon calculating process.

Few studies are found in literature on estimation of population quantiles using the method of ranked set sampling (RSS). The optimal RSS strategy is to select observations with at most two fixed rank order statistics from different ranked sets. In this paper, a near optimal unbalanced RSS model for estimating p^th(0 < p < 1) population quantile is proposed. Main advantage of this model is to use each rank order statistics and is distributionfree. The asymptotic relative efficiency (ARE) for balanced RSS, unbalanced optimal and proposed near-optimal methods are computed for different values of p. We also compared these AREs with respect to simple random sampling. The results show that proposed unbalanced RSS performs uniformly better than balanced RSS for all set sizes and is very close to the optimal RSS for large set sizes. For the practical utility, the near optimal unbalanced RSS is recommended for estimating the quantiles.

It is well known that internet shoppers are very sensitive to sale prices. They visit the various shopping malls and collect the product information including purchase conditions for goods purchase decision-making. Recently the necessity of information support is increasing because of increase of information amount which is necessary and complexity of goods purchase decision-making process. The comparison shopping agent systems have provided price comparison information which is collected from various shopping malls to satisfy internet shoppers information craving. But the frequent price change caused by keen price competition is becoming the primary reason of information quality decline among price comparison sites. RSS which is a family of web feed formats used to publish frequently updated is applied even in on-line shopping malls. This paper develops a RSS product information collection system to get real-time product information. The proposed product information system consists of (1) web crawler module for searching RSS feed shopping malls automatically, (2) RSS reader module for parsing product information from RSS feed file, (3) product DB and (4) product searching module. Performance of the proposed system is higher than the comparison shopping agent systems when it is defined with the volume of collecting product information per unit time.

In this paper, we purpose requirement capturing for RSS reader that be able to aggregate and subscribe to a RSS format document and describing for analysis model. We execute requirement analysis and documentation by using analysis model which is adopted use case model. And the method of requirement analysis is based on Responsibility Driven Design. Analysis model that is not premised on special reader is able to use business model.

RSS는 Web2.0의 키워드중 하나인 공유를 위해 정보를 빠르고 쉽게 배포하기 위한 시스템이다. 그러나 현재 RSS주소는 정보제공자에 의해 빈번하게 바뀐다. 이때문에 서비스의 에러가 발생하게 되어 정보의 신뢰성이 떨어지게 된다. 따라서, Static RSS의 구현을 통해 이문제를 해결 하고자 한다. Static RSS는 고정적인 RSS Code를 이용하여 빈번히 변경되는 RSS 주소를 관리 할 수 있다. RSS 주소가 변경 되더라도 RSS 코드는 고정되기 때문에 서비스 에러가 발생 하지 않는다. 이로 인해 정보를 영속성을 유지 시키고 정보의 신뢰성을 제공 할 수 있다.
