  • With improving computing performance, various digital platforms are being developed to enable easily utilization of high-performance computing environments. EDISON 1.0 is an online simulation platform widely used in computational science and engineering education. As the research paradigm changes, the demand for developing the EDISON 1.0 platform centered on simulation into the EDISON 2.0 platform centered on data and artificial intelligence is growing. Herein, a data framework, a core module for data-centric research on EDISON 2.0 digital platform, is proposed. The proposed data framework provides the following three functions. First, it provides a data repository suitable for the data lifecycle to increase research reproducibility. Second, it provides a new data model that can integrate, manage, search, and utilize heterogeneous data to support a data-driven interdisciplinary convergence research environment. Finally, it provides an exploratory data analysis (EDA) service and data enrichment using an AI model, both developed to strengthen data reliability and maximize the efficiency and effectiveness of research endeavors. Using the EDISON 2.0 data framework, researchers can conduct interdisciplinary convergence research using heterogeneous data and easily perform data pre-processing through the web-based UI. Further, it presents the opportunity to leverage the derived data obtained through AI technology to gain insights and create new research topics.

  • As shown in Wikipedia, tagging or cross-linking through major keywords in a document collection improves not only the readability of documents but also responsive and adaptive navigation among related documents. In recent years, the Semantic Web has increased the importance of social tagging as a key feature of the Web 2.0 and, as its crucial phenotype, Tag Cloud has emerged to the public. In this paper we provide an efficient method of automated in-text keyword tagging based on large-scale controlled term collection or keyword dictionary, where the computational complexity of O(mN) - if a pattern matching algorithm is used - can be reduced to O(mlogN) - if an Information Retrieval technique is adopted - while m is the length of target document and N is the total number of candidate terms to be tagged. The result shows that automatic in-text tagging with keywords filtered by Information Retrieval speeds up to about 6 $\sim$ 40 times compared with the fastest pattern matching algorithm.

  • 최근 연구성과정보의 원활한 교환 및 유통은 연구생산성 향상에 가장 핵심적인 요인으로 인식되고 있다. 그래서 국가적으로 그리고 각 연구기관에서는 연구성과정보 서비스를 위한 시스템을 계획하거나 구축 중에 있다. 그러나 연구정보들은 서로 다른 형태로 분산되어 있으며, 연구정보를 기술하는 방식에 있어서도 기관별 그리고 연구자 개인별로 많은 차이가 있어서 연구성과정보의 통합에 있어서 많은 제약이 있다. 따라서 본 연구는 시맨틱 웹 기술을 도입하여 연구성과정보의 메타데이터에 대한 상호운용성을 제고하는 방안을 제시함으로써 궁극적으로 연구성과정보의 통합을 지원하고자 한다. 특히 과학기술정보표준화위원회에서 제시한 연구성과정보 메타데이터 표준(안)을 기초로 개발되는 온톨로지는 용어들에 대한 구조적인 그리고 의미적인 통합을 가능하게 하며, RDF/RDFS를 이용한 메타데이터 지식표현은 정보 서비스의 검색과 유통에 있어서 지능적인 서비스를 가능하게 한다. 또한 본 연구를 통하여 제시한 시스템의 개념적 구조는 시맨틱 웹 기반의 검색시스템 개발에 있어서 주요 기능, 구성요소, 적용기술 및 상세 설계의 방향을 제시한다. 본 연구에서 제안한 메타데이터를 통한 시스템의 통합방식은 기존의 연구성과정보 시스템의 서비스 영역을 확대할 뿐 아니라, 더욱 정교해진 지능적인 검색 서비스도 가능하게 한다.

  • 본 연구는 우리나라 대표적인 정보학분야 학회지인 "정보관리학회지"에 25년 동안에 발표된 학술논문을 대상으로 동향분석을 시도하여 각 시기별 우리나라 정보학분야의 학문적 구조와 그 변화를 파악하였다. 이를 위하여 먼저 25년을 1984-1994, 1995-2002, 2003-2009로 나눈 다음, 각 기간별 "정보관리학회지"에 실린 학술논문의 주제를 분석한 후 각 논문의 주제분포, 주제영역별 논문의 증감, 주제영역별 연도 분포를 살펴보았다. 또한 논문의 표제어를 이용하여 기간별 정보학의 지적 구조를 생성하였고 세 개의 지적 구조를 비교하여 정보학 연구의 변화를 분석하였다. 그 결과 "정보관리학회지" 연구의 주요 대주제 영역은 '정보서비스', '정보조직' 그리고 '정보시스템'이며 소주제 영역은 도서관서비스, 이용자연구, 자동문헌처리, 도서관통합시스템, 시소러스/온톨로지, 디지털도서관인 것으로 나타났다. 또한 표제어의 지적 구조를 분석한 결과, 정보학의 핵심영역은 여전히 정보검색이지만 각종 도서관이나 시스템에 활용된 정보기술 기법이나 서비스 평가에 대한 연구가 점점 늘어나고 이에 대한 주제영역이 확장되고 있음을 알 수 있었다.

  • The National Institute of Environmental Research(NIER) launched a research about Framework of Environmental Health Information System for Industrial Complex in 2001, with the goal of finding out measures to establish an integrated management system(IMS) for environmental health information. Based on the research results, NIER started to build integrated information system. The process will continue from 2006 to 2008. As the first step, in 2006, NIER outsourced the job of setting up the specific plan. In 2007, based on the plan created in the previous year, computerization work began. During 2008, the $3^{rd}$ year of the process, the integrated system will be compatible to conventional GIS system and statistics analysis system to deliver funker efficient and useful services. In this vein, the objective of the study is to identify data collection procedure, data utilization, and overall goal of the system. In addition, It will illustrate digitalization process and recommendation about how to utilize the system.

  • Purpose: Researchers found that blocks of evidence-based practice (EBP) implementation lacked opportunities for EBP education. The study found that physical therapists had negative views of research as well as their roles in EBP, lacked confidence in EBP, and had limited access to web-based materials. The purpose of this study was to highlight the importance of information research technology for efficient EBP in a clinical environment. Methods: The web-based information research technologies that should be used for sustainable EBP include: the clinical practice guideline (CPG) and PubMed's My NCBI service. Journal mailing services and other academic information sources should also be used to gather information from RSS feeds. An EBP library or archive must be created. A site that provides EBP-specific information is also needed. Results: We should usually do EBP. Practitioners must learn and use information technologies that will help them improve their EBP skills. Conclusion: Facilitating EBP implementation and building an EBP system require related education as well as a practical work environment and equipment. However, the highest priority is individual efforts and trial. Information technology will complement the lack of time. It is important to use information research technology to overcome real obstacles. Lasting EBP must use a number of web-based information research technologies to overcome the practical challenges encountered in EBP implementation.

  • Keystroke dynamics user authentication is a behavior-based authentication method which analyzes patterns in how a user enters passwords and PINs to authenticate the user. Even if a password or PIN is revealed to another user, it analyzes the input pattern to authenticate the user; hence, it can compensate for the drawbacks of knowledge-based (what you know) authentication. However, users' input patterns are not always fixed, and each user's touch method is different. Therefore, there are limitations to extracting the same features for all users to create a user's pattern and perform authentication. In this study, we perform experiments to examine the changes in user authentication performance when using feature vectors customized for each user versus using all features. User customized features show a mean improvement of over 6% in error equal rate, as compared to when all features are used.

  • This study aims to provide the results of a case study, based on the action research approach, in which an user-oriented management system for enterprise information systems operational performance is successful developed and applied. This study performs the research and summarizes the results by adopting 5-step approach of action research, i.e., diagnosing, action planning, action taking, evaluating and specifying learning. The most important lessons learned from the study include (1) operation performance measures should be established to be shared by the management and users; (2) evaluation and improvement activities should be performed continually; and (3) formula to calculate the measure should be evolved so that improvement initiatives can be identified. The results of the study are expected to provide the companies intending to develop a management system for enterprise information systems operational performance with the practical and useful information. In addition, it is expected to suggest the research results that can be utilized as a basis for future research in this area.
