이 논문에서는 관계형 데이터베이스 모델 기반의 OWL 웹 온톨로지 모델을 보이고 이에 대한 실험 및 비교 평가 결과에 대하여 기술한다. OWL은 W3C에 의해 2004년 12월에 권고안으로 채택된 이후에 많은 연구가 진행되고 있다. 편집 도구 개발, 저장소 개발로 OWL 기반의 추론 엔진까지 이와 관련된 다양한 연구가 진행 중이다. 특히 OWL 온톨로지의 영구적인 저장 및 관리를 위해 관계형 데이터베이스 모델을 이용한 많은 연구 결과들이 발표되고 있다. 이 논문에서는 널리 알려진 관계형 모델 기반의 저장소 보다 나은 성능을 제공하기 위해 제안한 모델에 대한 평가 결과에 대하여 기술한다. 기존 유사 연구의 경우, 비교 평가를 위한 평가 항목으로 온톨로지 로드 시간을 고려하기도 하지만 이 논문에서는 질의응답 시간에만 초점을 둔다. 이는 매우 특수한 상황을 제외한 대부분의 상황에서 질의 처리 시간이 가장 중요한 요소이며 실질적인 활용성 측면에서 핵심적으로 다루어야 하는 평가 항목이기 때문이다. 실험을 위한 데이터로서는 많은 연구에서 활용하고 있는 LUBM 데이터 셋을 이용하며 실험 대상으로는 오픈 소스이며 널리 알려진 시스템인 Jena의 저장소와 Sesame를 이용한다. 실험 및 비교 평가 결과, 제안 시스템이 비교 대상 시스템들에 비해 나은 성능을 보임을 알 수 있다.

This study aims to develop and evaluate the authority data-based academic retrieval system that may provide search tools and additional information for search of academic papers with users. To evaluate the usability of authority data-based academic paper search system, this work studied 60 subjects who had experienced the academic paper service to measure their satisfaction on both search efficiency and system usability and additionally analyzed whether the difference between search efficiency and system availability is significant in the experimental search system among user groups. As a result, the authority data-based academic paper search system was analyzed to show a higher search efficiency and user satisfaction than the ordinary system.

It is practiced by many Korean medical institutions to give weights to medical papers published n foreign journals covered by major international abstracts and indexes (A&I) in the evaluation of research performance. In an attempt to recommend the databases to be used for the evaluation of KOrean medical research papers, this study measured the extent of overlap records of Korean medical papaers retrieved from the three major medical databases, EMBASE, MEDLINE and SCISEARCH. Korean papers published in foreign journals between 1990 to 1995 were analyzed. It also analyzed the characteristics of journals where these Korean medical papers are published with respect to their subjects, publishing countries and languages. It is found that these is no difference among three databsases as far as the characteristics of journals where Korean medical papers are published are concerned with respect to their subjects, publishing countries and languages. Thus the number of papers retrieved from each database should be the major criterion to recommend the A&I databases to be used in the evalua ion of research performance. If one database must be chosen for the evaluation of Korean medical papers, it is probably the best to utilize SCISEARCH which is the most efficient database for verifying Korean medical papers in foreign journals. If two databases can be used, then EMBASE should be the next choice.

The analysis platform of remote-sensing big data is a system that downloads data from satellites, transforms it to a data type of L3, and then analyzes it and produces its analysis results. The objective of this paper is to develop ISO/IEC 9126-1 software quality model-based assessment criteria, in order to evaluate the quality of remote-sensing big data analysis platform. Its detailed research contents are as follows. First, the ISO/IEC 9216 standards and previous software evaluation models will be reviewed. Second, this paper will define evaluation areas, evaluation elements, and evaluation items for measuring the quality of big data analysis platform. Third, the validity of the assessment criteria will be verified by statistical experiments through content validity, reliability validity, and construct validity, by using SPSS 20.0 and Amos 20.0 software. The construct validity will also be conducted by performing the confirmatory factor analysis and path analysis. Lastly, it is significant that our research result demonstrates the first evaluation criteria in measuring the quality of big data analysis platform. It is also expected that our assessment criteria could be used as the basis information for evaluation criteria in the platforms that will be developed in the future.

We are studying international standard about the software quality evaluation. The software quality has been more important on users and developers. In this paper, first, we study international tendency of the inside and outside of the country in software quality evaluation for evaluating the software quality objectively and quantitatively, Second, we notify a new direction for software quality standard of inside and outside of country. Third, we study on the testing method of software reliability for making use of the software reliability growth model. Fourth, we spread method about standard of the software quality evaluation, fifth, we research into the international standard ISO/IEC 9126 and ISO/IEC 25000 series for evaluation of software quality testing, and we propose to the application plan of software quality testing.

The recent change of educational evaluation puts particular emphasis on performance assessments which can appraise learning processes as well as learning results. The performance assessment is not only helpful for the improvement of teaching and learning methods, but also for making the learning activities significant to learners themselves. In this paper we propose and implement a system to support the internet-based and essay-typed performance assessment, in which student's performance can properly be evaluated. Teachers can be relieved from the burden of testing and provided with convenient methods of evaluation. We analyze the performance of the implemented system by evaluating practical usages of selected instructors and students group.

Recently, as smartphones are quickly spread to the general public, there are making a difference for use of information and communication methods. In this paper, mobile-based Performance Evaluation Management System(PEMS) that can make middle and high school teachers efficiently manage tasks of performance evaluation was implemented. That were applied to the performance evaluation of teachers. As a result, the tasks of teachers in the performance evaluation was reduced and teachers are able to concentrate on the guidance for students.
