Most university libraries in Korea have expanded the subscription of high-quality electronic resources in their amount and category, which are directly available to academic and research users via the web. Despite more than a decade's history, however, a lack of statistics made it difficult to get the overall pictures of electronic resources subscription status in Korea. The purpose of this study is to provide the analysis on nationwide statistics survey of how much money are spent on electronic resources, what kinds of subject resources are mainly subscribed, and how they are used and required by academic users, etc. Some comparisons are made with several factors that have effect on collection development of university libraries. This study will contribute to the future selection and subscription of electronic resources.

The journal is a important resource of the scholarly communication and it is a kind of the R&D indicator. But the journal subscription cost is rising annually so it has the limits to the journal subscription fee of libraries. This paper analyses the usage of Document Delivery Service(DDS) according to the journal subscription overlapping with NDSL members. In order to select journals for analysis, this paper selects journals of the subscription overlapping top 20% and low 20% and finds out the relationship between the overlapping subscription and usages of DDS.

In recent years, publish-subscribe (pub-sub) systems based on XML document filtering have received much attention. In a typical pub-sub system, subscribed users specify their interest in profiles expressed in the XPath language, and each new content is matched against the user profiles so that the content is delivered to only the interested subscribers. As the number of subscribed users and their profiles can grow very large, the scalability of the system is critical to the success of pub-sub services. In this paper, we propose a fast and scalable XML filtering system called SFiST which is an extension of the FiST system. Sharable segments are extracted from twig patterns and stored into the hash-based Segment Table in SFiST system. Segments are used to represent user profiles as Terse Sequences and stored in the Compact Segment Index during filtering. Our experimental study shows that SFiST system has better performance than FiST system in terms of filtering time and memory usage.

This study examines the way of making use of the science journals sharing with many users, who even do not work for the same institute. It may help to make the information as much as available with minimum financial burden to users. This is needed expecially when we recognize the fact that the amount of information supply is being increased rapidly while the financial environments around us are becoming aggravated.

The purpose of this case study is to analyze the economics of journals of Science and Technology using the cost per use(CPU) approach. To achieve this purpose, we selected 1,745 foreign academic journals randomly among the holdings at K institute in Korea, and analyzed the relationships between the CPU and 5 factors of journal, i.e., Impact Factors (IF), Overlap numbers of holding with other institutes, Language, Cost, and Frequency of use. It is found that all factors, except IF, are significantly influence to the CPU of foreign journals, and further detailed analysis is provided in term of the group differences within each factors.

This article analyzes the costs and benefits of the seven individuals centers of Foreign Research Information Center. Results of the investment feasibility analysis based on 30 years time span show that 0.99 of BCR (Benefit-Cost Ratio), 5.49% of IRR (Internal Rate of Return), and -507 million Won of NPV (Net Present Value). Sensibility analysis suggests that BCR can be influenced by the journal usage, social rate of discount, and elimination of the duplicate journal among individual centers.

The purpose of this study is to evaluate the foreign journals in the field of library and information science subscribed in Korean libraries. The journals were selected from the union catalogs and were analyzed by using the Excel program. The results shows that 1)issues of a particular journal are irregularly scattered in many libraries sometimes lacking many issues 2)some journals are duplicated in many libraries 3)there are great differences in the number of journal subscriptions depending on the geographical differences. It is expected that these results could be well used for the cooperative library services in the future.

그리드 컴퓨팅 기술을 기반으로 한 원격 실험 환경 구축에 있어서 원격 실험만큼이나 실험결과 데이터를 저장하고 재연하는 것이 중요하게 대두되고 있다. 본 논문에서는 KOCED 프로젝트의 건설 연구 실험시설 중 하나인 실시간 하이브리드 다자유도 실험시설에 대한 프로토타입인 원격 하이브리드 실험에 대하여 나라다 브로커링 이라는 발간 및 구독 패러다임의 스트리밍 서버와 글로버스 툴킷에 기반 한 리코딩 및 리플레이 서비스를 통하여 실험결과 데이터를 저장하고 재연하는 시스템을 구축 하였다. 기존에 진행된 실험결과를 검색하여 볼 수 있게 함으로써 중복된 실험으로 인한 비용을 줄이고, 사용자가 원하는 데이터에 대한 토픽정보를 통하여 재연함으로써 실험결과 데이터의 효용성을 높일 수 있을 것으로 판단된다.

Recently electronic journal articles prevail throughout researchers because of the development of internet and electronic publishing technology. It is caused by limited collection development budget, lack of physical storage space for printed journals in libraries, and the user convenience of web services. But from the view of ownership, electronic journals can be unfavorable to information users or libraries who cannot have the permanent right to access all the subscribed journals. Actually the libraries only have right to access journals for subscription periods in using electronic journals. So the users and libraries are willing to purchase printed journals in spite of high cost. As an basis for collaborative collection development and sharing preservation of Korean libraries for the foreign journals, the data analysis is carried out for the journals collection in terms of regional distribution, overlapping status, and journal subject. And the considerables are discussed for collaborative strategic collection development, which means the reduction of overlapped subscription and maximization of utilization in a national standpoint.
