Collider physics based on e-Science paradigm of experiment–computing–theory

Researches in the 21st century are characterized by e-Science paradigm, which is the data centric analysis as a unified concept of experiment–computing–theory. In this paper the e-Science paradigm has been realized in collider physics by constructing the unified research environment of experiment–theory and theory–computing as well as that of computing–experiment performed at KISTI (Korea Institute of Science and Technology Information). In other words, the fusion concept of collider physics of experiment, computing and theory has been applied. The goal of this approach is to study collider physics anytime, anywhere for more efficient research process. The construction of e-Science paradigm of experiment, computing and theory in collider physics provides us with new research methodology in computational physics.

Design of Subject-based Community Model by Linkage Heterogeneous Content: Focused on Field of Biological Science

Researchers in Korea and elsewhere have carried out a wide variety of important research activities in their respective fields, producing valuable research results. For such diverse research results to be shared and exchanged among researchers working in the same discipline and research subject there needs to be a community environment based on free utilization of information. Against this backdrop, this study seeks to classify and reprocess the reference/factual content owned by the KISTI (Korea Institute of Science and Technology Information), a state-run distributor of information on science and technology, by the different research subjects. It also seeks to develop and provide a community model based on the concepts of open archiving and open access for the researchers specialized in the related fields of research. This community model is developed focusing on the research results from the field of bioscience, where the most extensive studies are currently being conducted. To develop the community model, this study: (a) surveys the current status of the content owned by KISTI; (b) analyzes the patterns and characteristics of biological scientific content among the KISTI-owned content; and (c) designs a web platform where researchers can freely upload/download research results.

Genbank 분석을 통한 이종의 콘텐츠 연계 방안 설계

유전자 서열정보는 그 양이 방대하고 다양하기에 DB 구축 및 분석을 위하여 고성능 컴퓨터 및 정보기술 기법이 필요하다. 그래서 컴퓨터를 활용하여 생물학적 데이터를 수집, 관리, 저장, 평가, 분석하는 연구분야인 생명정보학이라는 학문이 지속적으로 발전하고 있다. 이런 생명정보학 발전에 발맞추어 한국과학기술정보연구원(KISTI)에서는 정보기술 기반 생명정보 인프라를 구축하여 생명과학 연구자들에게 제공하고 있다. 본 논문에서는 생명정보 DB 중에서 전세계 연구자들이 가장 많이 이용하는 유전자 DB인 Genbank의 reference 필드를 분석하여 한국과학기술정보연구원(KISTI)의 과학기술정보 통합서비스인 NDSL (http://NDSL.kr)과의 연계 방안을 제안하고자 한다. 이를 위하여 NCBI FTP 사이트에서 Genbank 데이터를 수집하여 Genbank 텍스트 파일을 유전자 기본정보와 참고정보로 나누어 DB로 재구축하였으며 Genbank reference 필드에서 논문 및 특허 정보 추출을 통한 새로운 테이블을 생성하였고, KISTI의 논문 DB (http://scholar.ndsl.kr), 특허 DB (http://patent.ndsl.kr)와의 연계 방안을 제시하였다. As information on gene sequences is not only diverse but also extremely huge in volume, high-performance computer and information technology techniques are required to build and analyze gene sequence databases. This has given rise to the discipline of bioinformatics, a field of research where computers are utilized to collect, to manage, to save, to evaluate, and to analyze biological data. In line with such continued development in bioinformatics, the Korea Institute of Science and Technology Information (KISTI) has built an infrastructure for the biological information, based on the information technology, and provided the information for researchers of bioscience. This paper analyzes the reference fields of Genbank, the most frequently used gene database by the global researchers among the life information databases, and proposes the interface method to NDSL which is the science and technology information integrated service provided by KISTI. For these, after collecting Genbank data from NCBI FTP site, we rebuilt the database by separating Genbank text files into the basic gene data and the reference data. So new tables are generated through extracting the paper and patent information from Genbank reference fields. Then we suggest the method of connection with the paper DB and the patent DB operated by KISTI.

KISTI에 있어서 한국인 인체정보의 생산과 활용

한국과학기술정보연구원(KISTI)는 2000년부터 한국인의 고유한 인체 특징을 나타낼 수 있는 디지털코리언, 비저블 코리언이라는 한국인 인체정보 구축사업을 시작하였다. 비저블 코리언 사업은 한국인 시신에 대해 CT, MRI 영상을 촬영한 다음 연속 절단하여 절단면 영상을 얻고 이 절단면 영상에서 인체장기를 구역화하여 구역화 영상을 제작하였다. 남성 및 여성 전신과 남성 머리 및 여성 골반의 절단면영상 제작을 마쳤으며 현재 구역화 영상을 이용한 3D 영상 제작이 진행 중이다. 디지털 코리언 사업은약 100여명의 한국인 시신에 대해 촬영한 CT 영상으로 구성되어 있는데 CT 영상으로부터 개별 뼈를 구역화하여 3D 골격 모델을 제작하였고 피부 모델도 추가하였다. 또한 개별 뼈들의 기계적 물성값도 측정하여 제공하고 있다. 이러한 인체정보들은 2001년부터 국내외 연구자들에게 제공되어 왔는데 지금까지 국내 약 70여개 기관, 해외 약 20여개 기관들이 한국인의 인체 데이터를 제공받아 연구 활동을 진행하고 있으며 지금까지 약 160여 논문이 발표되었다. 향후에도 이러한 한국인의 인체정보는 의료 교육, 생체공학, 가상현실 등의 다양한 분야에 활용될 의료정보 인프라의 역할을 담당할 것으로 기대하고 있다. The KISTI (Korea Institute of Science and Technology Information) began to produce the Korean human information called Visible Korean and Digital Korean since 2000 because there was no human information in Korea which could represent the physical characteristics of Korean human body. The Visible Korean consists of CT, MR, sectioned and segmented images of Korean human body. We obtained the serially sectioned images by grinding the Korean cadaver in horizontal direction and segmented these images by outlining the inner organs of human. We have produced the sectioned images of Korean male whole body, male head, and female pelvis in2008. The segmentation and 3D reconstruction of these images are now in proceeding. The Digital Korean consists of CT images of about 100 Korean cadavers. These CT images were segmented by individual bone, reconstructed to produce the 3D bone models and the skin surface model was also added. The mechanical properties of individual bones were obtained by measuring the property of individual bone sample. We have distributed these Korean human informations to users in domestic and abroad. About 70 institutes in domestic, and 20 institutes in abroad have used our data in research use and nearly 160 proceedings and articles were published since 2001. We think these human informations have a role of medical information infrastructure that could be used in the field of medical education, biomechanics, virtual reality etc.

Using Guasha to treat musculoskeletal pain: A systematic review of controlled clinical trials

BackgroundGuasha is a therapeutic method for pain management using tools to scrape or rub the surface of the body to relieve blood stagnation. This study aims to systematically review the controlled clinical trials on the effectiveness of using Guasha to treat musculoskeletal pain.MethodsWe searched 11 databases (without language restrictions): MEDLINE, Allied and Complementary Medicine (AMED), EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Korean Studies Information (KSI), DBPIA, Korea Institute of Science and Technology Information (KISTI), KoreaMed, Research Information Service System (RISS), China National Knowledge Infrastructure (CNKI) and the Cochrane Library. The search strategy was Guasha (OR scraping) AND pain. Risk of bias was assessed with the Cochrane criteria (i.e. sequence generation, blinding, incomplete outcome measures and allocation concealment).ResultsFive randomized controlled trials (RCTs) and two controlled clinical trials (CCTs) were included in the present study. Two RCTs compared Guasha with acupuncture in terms of effectiveness, while the other trials compared Guasha with no treatment (1 trial), acupuncture (4 trials), herbal injection (1 trial) and massage or electric current therapy (1 trial). While two RCTs suggested favorable effects of Guasha on pain reduction and response rate, the quality of these RCTs was poor. One CCT reported beneficial effects of Guasha on musculoskeletal pain but had low methodological quality.ConclusionCurrent evidence is insufficient to show that Guasha is effective in pain management. Further RCTs are warranted and methodological quality should be improved.

New Frontiers for Scientific and Technical Information

The International Council for Scientific and Technical Information (ICSTI) held its 2008 Public Conference in Seoul, Korea from 11th to 12th June, 2008. This was a departure from recent practice – it has been more typical for ICSTI public conferences to be held in Europe and North America. The decision to hold the 2008 Summer Conference in Korea was fully vindicated by the results. It was a very well organised event for which the local host – Korea Institute of Science and Technology Information (KISTI) – can claim full credit. Attendance was well over three hundred, some two to three times the usual ICSTI numbers at such events. Each attendee received a comprehensive programme guide and proceedings which proved invaluable as support material for the presentations. Leading experts from across the world shared their views and experiences with the audience. Included within the programme was the formal international launch of a major new initiative sponsored by ICSTI. Overall the logistics went very smoothly and professional staff ensured that the conference at the CODEX International Hotel, and the related social programmes, were a great success. This was a perfect template for a revitalised ICSTI and sets a standard for future conferences including the 2009 to be held under CISTI’s auspices in Canada. Everyone involved in the Seoul 2008 Public Conference, particularly the local hosts KISTI, are to be congratulated for their organisation and attendance to detail.

계량정보분석시스템으로서의 KnowledgeMatrix 개발

데이터베이스로부터 지식을 발견하고 이를 연구기획자, 정책의사결정자들이 활용하는 움직임이 전세계적으로 활발해지고 있다. 이러한 연구분야 중 대표적인 것이 계량정보학이고 이 분야를 지원하기 위해서 주로 선진국을 중심으로 분석시스템이 개발되고 있다. 그러나 외국의 분석시스템은 실제 수요자의 요구를 충분히 반영하지 못하고 있고, 고가이면서 한글이 지원되지 않아 국내 연구기획자가 사용하기에 어려운 점이 있다. 따라서 한국과학기술정보연구원에서는 이러한 단점을 극복하기 위해서 계량정보분석시스템 KnowledgeMatrix를 개발하였다. KnowledgeMatrix는 논문 및 특허의 서지정보를 분석하여 지식을 발견하기 위한 목적으로 설계된 독립형(stand-alone) 시스템이다 KnowledgeMatrix의 주요 구성을 살펴보면 행렬 생성, 클러스터링, 시각화, 데이터 전처리로 요약된다. 본 논문에서 소개하고 있는 KnowledgeMatrix는 외국의 대표적인 정보분석시스템과 비교했을 때 다양한 기능을 제공하고 있고 특히 영문데이터 처리 이외에 한글데이터 처리가 가능하다는 장점을 갖고 있다. Application areas of Knowledge Discovery in Database(KDD) have been expanded to many R&D management processes including technology trends analysis, forecasting and evaluation etc. Established research field such as informetrics (or scientometrics) has utilized techniques or methods of KDD. Various systems have been developed to support works of analyzing large-scale R&D related databases such as patent DB or bibliographic DB by a few researchers or institutions. But extant systems have some problems for korean users to use. Their prices is not moderate, korean language processing is impossible, and user's demands not reflected. To solve these problems, Korea Institute of Science and Technology Information(KISTI) developed stand-alone type information analysis system named as KnowledgeMatrix. KnowledgeMatrix system offer various functions to analyze retrieved data set from databases. KnowledgeMatrix's main operation unit is composed of user-defined lists and matrix generation, cluster analysis, visualization, data pre-processing. Matrix generation unit help extract information items which will be analyzed, and calculate occurrence, co-occurrence, proximity of the items. Cluster analysis unit enable matrix data to be clustered by hierarchical or non-hierarchical clustering methods and present tree-type structure of clustered data. Visualization unit offer various methods such as chart, FDP, strategic diagram and PFNet. Data pre-processing unit consists of data import editor, string editor, thesaurus editor, grouping method, field-refining methods and sub-dataset generation methods. KnowledgeMatrix show better performances and offer more various functions than extant systems.

과학기술 정보유통을 위한 업무 프로세스 표준화

최근에 많은 정부출연 연구기관과 정보유통서비스 기관들이 ISO 9001 품질경영시스템을 도입하여 그들 조직의 업무 수행도를 향상시키는데 대한 관심이 두드러지게 증가하고 있는 실정이다. 하지만 도입시에 조직의 특성 및 현황을 제대로 반영하지 않아서 시스템의 요구사항과 프로세스가 지향하는 목표화의 현실적 차이 때문에 ISO 9001 품질경영시스템 운영에 따른 효과를 제대로 누리지 못하고 있다. 이에 한국과학기술정보연구원(KISTI)은 프로세스 표준화를 통한 생산성 증대 및 조직의 경쟁력 증가를 위해 ISO 9001 시스템의 요구사항을 반영하기 위한 프로세스 분석을 통하여 표준시스템 지향적 프로세스를 도출하였다. 그 결과, KISTI는 2003년 11월 11일에 ISO 9001:2000 인증을 받았고, 품질경영 업무를 수행함으로서, 고객 만족도 증가, 업무의 효율성 증대 및 업무처리 시간 단축 등의 효과를 얻을 수 있었다. Recently, numerous government institutions and information service organizations have shown interests in employing ISO 9001 Quality Management System(QMS) to increase their organizational performances. However, due to the gap between the system requirements and the process oriented goals in reality, they have not been able to merit from the ISO 9001 QMS. So, Korea Institute of Science and Technology Information(KISTI) has been designed a process oriented system by incorporating the process analysis results into the existing ISO 9001 system requirements for enhancing organizational competitiveness and promoting productivity through a process standardization. As a result, KISTI has been ISO 9001:2000 certificate in November 11, 2003. And we obtain a improvement of customer satisfaction and efficiency of work, reduction of work processing time using KQMS.

Semantic Web-Based Services for Supporting Voluntary Collaboration among Researchers Using an Information Dissemination Platform

Information dissemination platforms for supporting voluntary collaboration among researchers should assure that controllable and verified information is being disseminated. However, previous related studies on this field narrowed their research scopes into information type and information specification. This paper focuses on the verification and the tracing of information using an information dissemination platform and other Semantic Web-based services. Services on our platform include information dissemination services to support reliable information exchange among researchers and knowledge service to provide unrevealed information. The latter is also divided into the two: knowledgization using ontology and inference using a Semantic Web-based inference engine. This paper discusses how this platform supports instant knowledge addition and inference. We demonstrate our approach by constructing an ontology for national R&D reference information using 37,656 RDF triples from about 2,300 KISTI (Korea Institute of Science and Technology Information) outcomes. Three knowledge services including 'Communities of Practice', 'Researcher Tracing,' and 'Research Map' were implemented on our platform using a Jena framework. Our study shows that information dissemination platforms will make a meaningful contribution to the possibility of realizing a practical Semantic Web-based information dissemination platform.

The development of KACD(korean academy of conservative dentistry) online article contribution management system based on KISTI-ACOMS

Societies are important sources of new information for users. However. most of these societies still rely on traditional. or rather ancient methods for gathering and servicing the information. Furthermore. most of the societies are trying to electrify processes such as managing members and paper submission as well as the process managing the information for service but are limited due to financial and technical reasons. Therefore. KISTI(Korea Institute of Science and Technology Information) has developed the KISTI-ACOMS(KISTI-Article COntribution Management System) as part of the national project for automating the process of processing academic information by societies. in order to convert journals published by academic societies in Korea into an electronic form and make them accessible on the Internet. This system has been developed in the year 2001 and has since been distributed to societies free of charge. The number of societies requesting the service has risen recently. which prompted us to take more recommendations of the societies that adopt this system into account in expanding and standardizing the area of service being provided by the system.

Usage patterns of an electronic theses and dissertations system

The Korea Institute of Science and Technology Information (KISTI) Electronic Theses and Dissertations (ETD) system is a national digital library of ETDs in South Korea. Provides a comprehensive picture of how this system has been used during its first two years in service since June 1999. The system transaction logs were collected and analysed to reveal the usage patterns of the system. Results of the study indicate that the KISTI ETD system usage has seen a significant increase since its second year. While most users appear to be domestic users, the system also attracts users from many other countries, suggesting that the KISTI ETD system has become a part of the international networked digital library of theses and dissertations. It was also found that there are a very large number of one‐time visitors to the KISTI ETD system. Nevertheless, the system began to maintain a frequent user group in its second year in service. The usage statistics regarding system features and the characteristics of users’ visits indicated that the search function was by far the most frequently used system function. Finally, discusses the implications of the findings.
