시맨틱웹의 실용화에 대한 연구가 활기를 띠면서 국내에서도 시맨틱웹에 관한 연구와 그 기반이 되는 온톨로지에 대한 관심이 높아지고 있다. RDF, DAML+OIL 등 많은 온톨로지 언어가 개발되었고 W3C는 2004년 2월 OWL(Web Ontology Language)을 온톨로지를 위한 표준 언어로 발표했다. 이와 함께 프로티지 등 온톨로지 개발을 위한 편짐 도구들에 관한 연구도 진행되고 있다 본 논문에서는 기존 편집기의 문제를 지적하고 새로운 편집 방법을 통한 온톨로지 편집기를 개발하였다. 이 편집기는 가장 널리 사용되고 있는 온톨로지 개발도구인 프로티지와 그 위에서 작동하는 OWL plug-in을 기반으로 한다.

In school science class, actual geological field trips tend to be restricted due to a number of problems including travel distance, cost, safety, and so on. Therefore, alternative way should be sought to provide students with the benefits of actual field trip. The purpose of this study is to develop web-based virtual field trip (VFT) about Jeju island in Korea by using flash panorama, and to explore a variety of ways to utilize the VFT. The characteristics of Jeju VFT are as follows: it provides virtual space for secondary school students to learn about volcanic topography and geology; students can access contents in a non-sequential order by virtue of web-based system, and students can control learning pace according to their ability; it is possible to investigate the same field site repeatedly, not limited by time and space; it presents differentiated worksheets for different school grade; it provides diverse complementary web contents, e. g., closeup features, thin sections, inquiry questions, and explanations of outcrops. We proposed several ways with instructional models to utilize Jeju VFT in science class and extra-school curricular as well.

With advancement of computer and network, world wide web(WWW) as medium of information communication is generalized in many fields. In educational aspect, applications of WWW as alternative media for class teaching or printed matter are increasing. In this article, we demonstrate a web based electronic text on the 'probability and statistics' which is one of six fields of mathematics in 7th curriculum. This text places importance on comprehension of concepts and fundamentals of probability and statistics as applied sciences and not on simple calculations of probability and statistics.

The laboratory time for students in engineering has to be managed in that way that it provides students width maximal practice hours. However, it usually takes too much time to learn basic knowledge for the experiment and the directions of the equipment. In this paper, we introduce the web contents which students can study basic knowledge the directions of the equipment without regard to time or place. As the result that we let students study the contents before the class, they were easily adapted to handle the equipments for the experiment so that we can revise their execution abilities. And also there were effects such as reducing the total experiment's time and a rate of damage of equipment.

This paper makes a general description of the results at government project which were peformed for several years. Through this project, the real capacity of 3.3KV/4MW Class 3 Level Voltage Source Inverter System were designed and the characteristics of its proto type were analyzed, moreover the web based IIMS(Inverter Information Management System) and Virtual Operation Simulator was developed. Now, this system is running for field application test.

In the latter half of the 1980's, Systematical Western Archival Science theory was introduced in Japan especially, provenance principle which is fundamental theory in arrangement, original order principle and understanding in level of archives groups. However, they just confirmed public records arrangement theory having done in each Prefectural Archives(文書館) in Japan since 1960's and embodied it. Among them, National Archives of Japan(國立公文書館) just followed arrangement method each ministry and office did. And Saitama Prefectural Archives(琦玉縣立文書館) grasped changes of the name of department, class, standard by class and organization and its affairs before public records arrangement. On the one hand, Japan Center for Asian Historical Records(JACAR: アジア歷史資料セン夕-) is attending on public records by web which National Archives of Japan. The Diplomatic Record Office of the Ministry of Foreign Affairs(外務省外交史料館). The National Institute for Defense Studies(NIDS : 防衛廳防衛硏究所) have. JACAR arranged the public records based on provenance principle following arrangement system they have.

This paper describes an experiment of concrete and specific group work learning system based on the traditional Jigsaw group work learning model. Jigsaw model has two groups of students such as random group and expert group so that a course can make progress on explaining and lecturing all members of class after each student can be a member of expert group of course topic. We design and implement Web-based training system to support collaboration and Interaction among students of a course based on Jigsaw model The Web- based learning system makes each group going up to the expert level of a course subject by supporting various study menu and provides equal opportunity of improving social abilities such as leadership, communication skill, trust, and trouble-settling by taking part in collaboration activities.

Purpose: Health care professionals represent an immediately available resource to promote smoking cessation. However, the content in smoking cessation intervention courses in most institutions is insufficiently covered due to the limited number of class hours. The purpose of this study was to develop a comprehensive tobacco cessation-web-based, multimedia, educational program for a range of medical professionals. Methods: Based on Jung's Teaching and Learning Structure Plan Model, a development process was proposed comprising four stages: (1) analysis, (2) planning, (3) production, and (4) operation/evaluation. The effectiveness of the program was tested using quasi-experimental design, and the participants in experimental group were required to complete the program. Changes in the level of knowledge and attitude were measured. Results: The educational program developed includes nine topics and 26 sub-topics. A total of 180 storyboards, 15 videos, and 27 pictures were made. After the education, the level of knowledge was significantly increased in the experimental group. Conclusion: This web-based program can be recommended as a potential medium for health care professionals to use in counseling smoking cessation. The study findings also indicated that the program may be either offered as a teaching aid or utilized concurrently with lectures for students studying health care-related topics.

Today, due to the 4th industrial revolution and extensive R&D funding, domestic companies have begun to possess world-class industrial technologies and have grown into important assets. The national government has designated it as a "national core technology" in order to protect companies' critical industrial technologies. Particularly, technology leaks in the shipbuilding, display, and semiconductor industries can result in a significant loss of competitiveness not only at the company level but also at the national level. Every year, there are more insider leaks, ransomware attacks, and attempts to steal industrial technology through industrial spy. The stolen industrial technology is then traded covertly on the dark web. In this paper, we propose a system for detecting industrial technology leaks in the dark web environment. The proposed model first builds a database through dark web crawling using information collected from the OSINT environment. Afterwards, keywords for industrial technology leakage are extracted using the KeyBERT model, and signs of industrial technology leakage in the dark web environment are proposed as quantitative figures. Finally, based on the identified industrial technology leakage sites in the dark web environment, the possibility of secondary leakage is detected through the PageRank algorithm. The proposed method accepted for the collection of 27,317 unique dark web domains and the extraction of 15,028 nuclear energy-related keywords from 100 nuclear power patents. 12 dark web sites identified as a result of detecting secondary leaks based on the highest nuclear leak dark web sites.
