한반도 국가바람지도(김현구, 2009)는 한국에너지기술연구원에서 지식경제부의 부처임무사업으로 구축되었으며 현재 웹서비스(http://www.kier-wind.org)를 통하여 정보를 제공하고 있다. 국가바람지도는 수치기상예측(NWP; Numerical Weather Prediction) 모델을 이용하여 영토, 영해에 대해 $1km{\times}1km$의 고해상도로 작성한 뒤(이순환 등, 2009) 풍력자원 정보로 재가공되었다. 한반도 국가바람지도는 5년의 장기간에 대한 시계열 수치기상예측에 의하여 구축되었기 때문에 데이터베이스(DB; database)의 효율적 관리가 필연적으로 요구된다. MM5 또는 WRF 모델의 고유 출력포맷의 자료구조는 풍력자원분석에 필요한 기상요소 외에도 대기과학자에게 필요한 수많은 기상인자를 종합적으로 포함하고 있다. 따라서 2차원 층(layer) 또는 3차원 공간분포 분석 및 계산격자인 셀(cell)에서의 1차원 시계열 분석 등 다양한 자료축출에는 비효율적인 자료구조가 된다. 이러한 자료구조의 불편을 해소하기 위해서는 기상요소별로 독립적이고 빈번한 시계열 자료 추출에 효율성을 가지며 어떤 프로그래밍 언어를 사용하든지 직관적으로 쉽게 사용할 수 있는 바람지도 데이터베이스의 재구성이 요구된다. 이에 대용량 수치자료의 처리 측면에서 장점을 가지는 과학기술 프로그래밍 언어인 IDL을 기반으로 국가바람지도의 자료구조를 효율화하여 데이터베이스화 하였으며 IDL에 내재된 그래픽 기능을 활용하여 가시화를 구현함으로써 연구개발자의 입장에서 국가바람지도의 활용성 및 효율성을 향상시키고자 하였다.

To improve the international competitiveness of research and academic libraries in Korea, it is essential to review the total amount of domestic information resources in comparison with those of other advanced countries, and then to make their best use. In this study, an attempt is made to estimate the annual budget for collecting foreign knowledge information resources spent by academic and research libraries in Korea. This budget estimate could be used for a basis for setting up the appropriate collection size and the efficient channel for distributing and sharing information resources among academic and research libraries on the governmental level. The total budget for collecting foreign knowledge information resources, including foreign monographs and scholarly journals in print, and the budget for foreign electronic journals, and web databases were estimated for academic libraries and research libraries, respectively, while the budget for international document delivery services was estimated without distinction between the types of libraries.

We studied the methods for boosting a user participating service using KOSEN(The Global Network or Korean Scientists and Engineers) OpenLab service. OpenLab is a laboratory database of all the fields of science and technology, and it is different from other services in that basically it makes users register their information volunteerly. User participation service is not easy, so we made several strategies like promotion, event, and connection to other services. In result, we could collect about 4,300 laboratory database. Because user participation is a key concept for the Web 2.0, this study would contribute to the operation of the related services, especially to the services for scientists and engineers.
