Convergence is an important concept for driving our society to be ubiquitous. The objectives of this paper are to conceptualize information convergence, and to analyze its mechanisms from the view of ubiquitous library circumstances. Further, this paper suggests mobile Web 2.0 as a library supporting technology for information convergence and some kinds of mobile based library user services using mobile Web 2.0 applications.

In a Digital Age contents are comprized of knowledge and information. Also distinction between the sinner and loser is very clear thus only those who can rise up to challenge of changes can become the strong and a principal player. In this study this author presented a model for forecasting information service program(FISP) which is devised for the purpose of innovation of service pattern related to providing information which is ultimate goal of a library. This model is an innovative strategy escaping boldly from negative and inactive information service pattern known in analog age. Through this model this author attempted to outline methodology for heightening ideal of professional librarians and for assuring success in organizational system.

The Korean government is pursuing the policy of broadening easy access to information by local residents and the range of public services provided to them. One of the most recent prominent examples is the evening circulation service offered by public libraries. In a sense of addressing issues facing the newly implemented service, this study aimed to present an improvement scheme on the basis of the results from analyzing the data such as background motivation, ways of publicity, service open time, service content, the present status of use of materials, satisfaction of users, and operating difficulties experienced, which were attained from the public libraries implementing the service as of June 2009 and the service users.

Most public libraries construct and operate their websites to provide the various user groups in local communities with internet access in Korea. But the representative public library's websites designed for children who are going to lead the next generation information based society, are unsatisfactory and don't reflect their approaches to information. The main factors of content and circumstance of usage are also extremely poor. Therefore, this research analyzed the construction of websites for children, their interface and design, search services, the contents of provincial representative public libraries amongst public libraries in korea and suggested improvement schemes.

소프트웨어 정의 네트워크(Software-Defined Networking; SDN) 기술은 기존 네트워크 기술의 폐쇄성과 복잡성의 한계를 극복하고, 중앙 집중적 관리 및 프로그래밍 기반의 네트워크 서비스를 제공할 수 있는 장점이 있다. 그러나 SDN 환경에서도 다른 네트워크 환경처럼 악의적인 DDoS 공격으로 인해 전체 네트워크 서비스가 마비될 수도 있는 문제가 있다. 이러한 문제를 해결하기 위한 기존의 연구들은 공격이 인입되는 스위치 포트를 차단하거나, 공격자의 출발지 주소 자체를 차단하는 기법 등이 있으나 공격 트래픽과 함께 정상 트래픽까지 차단하는 문제가 있다. 본 논문에서는 SDN 환경에서 DDoS 공격 발생 시 악의적인 트래픽만 방어하고, 정상적인 트래픽은 최대한 허용하는 서비스 Flow 기반의 방어 기법을 제안한다. 제안 기법은 SDN 환경에서 Flow 분석을 통해 DDoS 공격을 탐지한 후 이를 접근제어 리스트 방식을 통해 공격 트래픽만을 차단하는 것이 가능하다. 실험 결과를 통해 공격자의 악의적인 트래픽은 차단하고, 정상적인 트래픽은 허용하는 것이 확인되었다.

This study, through the use of the comparative method, intends to contribute to the effective and productive use of Korea's STI. This study first tries to understand the nature of ST1 as well as the development in the field of science and technology in Korea. And then, the historical background of the two leading ST1 centers. KINITI(Korea Institute of Industry & Technology Information) and KORDIC(Korea Research & Development Information Center), is described. Furthermore, the ST1 structures of KINITI and KORDIC are compared and analyzed in the light of their network, collection development, databases, and information services. Finally, based on these findings, this study tries to make some policy recommendations.

한국과학기술정보연구원에서는 슈퍼컴퓨터 5호기 시스템 및 가속기 기반 시스템을 국내 연구자들에게 서비스를 하고 있다. 시스템 관리자들은 시스템 상태 조회 및 통계 정보 산출등의 목적으로 배치 작업 관리 솔루션에 주기적으로 다양한 정보의 요청을 수행한다. 빈번한 정보 요청은 작업관리 솔루션에 부하를 줄 수 있다. 본 논문에서는 사용자들의 배치 작업 관리를 위해 사용하는 배치 작업 관리 솔루션인 PBSPro와 SLURM을 활용한 효율적인 시스템 모니터링 기법을 설계하고자 한다.

National Research Data Commons aims to build a system that can be used jointly by arranging analysis resources such as computing infrastructure, software, toolkit, API, and services used for data analysis together with research data to maximize the use of research data. do. The sharing and utilization system for publications and research data in the R&D process is well known. However, the environment in which data and tightly coupled software and computing infrastructure can be shared and utilized is insignificant and there is no management system. In this study, a data model is designed to systematically manage information on digital research resources required in the data-oriented R&D research process. This will be used to register and manage digital research resource information in the National Research Data Commons Service.
