When a designer creates a new web-based learning-teaching system, there are so many considerations to help learners' learning effect through effective interaction. First of all, web-based simulation is recommended to provide learners with effective and attractive learning environments in web. Efficient study design should be considered because well designed simulation-based contents provide continuous interest for learner. Until now many e-Learning systems provide web-based simulation using various technique. However, those contents require to be reorganized considering the level of accomplishment, learning styles. In this paper, I proposed a system that the learners can share simulation objects among other e-Learning systems using XML web service. By experimental result, the proposed system shows that is more efficient than the conventional system in the self-leading study activity and interactivity.

In field of school, parents can't attend to education activities of school really because of the time and spacial reason, economical reason and the sense of distance for school, although they are very concerned about a school education. In this paper, I suggested the e-Home system that is an organic system to can confirm the communication channel between parents and school or teacher by using infrastructure of educational information based on established Home-page of each school. It should bring a qualitative promotion for public education. Of couse, it will be increasing a relationship of student, teacher and parents furthermore, it make a desirable relation between teacher and parents via participation of parents for school education in elementary school.

By virtue of the advanced Internet technology, there are lots of research works for e-Logistics which means virtual business activities or service architecture based on the Internet among the logistics companies. Because e-Logistics environment requires more dynamic and global service area, conventional vehicle monitoring and control technologies innate many problems in terms of Integrating, storing and sharing the location data. It needs the development of the moving object technology in order to resolve efficiently the limitations. In this paper, we propose the whole components of the moving object management system which supports the advanced sharing the location information as well as the integration of location data. We are sure the suggested system can be adopted to construct the next generation-logistics vehicle monitoring and control system by reducing the overall cost and time.

The purpose of this study is to identify the problems of the e-book composition provided by the Comprehensive Reading Education Support System and to propose a service improvement plan related to the establishment of e-books in school libraries as educational resources based on practical issues and perceptions experienced by teacher-librarians. As a research method, the composition of the collection of 3,002 e-books supported by the Busan Comprehensive Reading Education Support System as a reading education platform of the school library was analyzed based on the Korean Decimal Classification. Based on this, two focus group interviews (FGI) were conducted with 4 elementary teacher-librarians and 5 secondary teacher-librarians working in Busan. The result of this study can be used as basic data to support students' reading activities using e-books as educational resources and to form an efficient e-book collection in school library.

본 논문에서는 시스템 사고를 이용한 이러닝 서비스의 정보보호관리를 제안하였다. 이러닝 활용이 증가되면서 이러닝 시스템에 불법적인 접근을 통한 정보의 유출, 변조, 삭제 등 다양한 위협 요인도 병존하고 있기 때문에 정보자산에 대한 위협 및 위험요소에 대한 체계적인 대책과 지속적인 관리의 중요성이 지속적으로 증가하고 있다. 현재 이러닝 운영 기관에서 정보자산을 보호하기위해 다양한 정보보호 활동과 노력을 하고 있으나, 하루가 다르게 변화하고 있는 IT 환경에서는 조직의 운영 환경과 여건에 맞게 정보자산을 보호하기 위해서 시스템 사고를 활용한 동태적인 관리가 종합적이고 지속적인 정보보호관리체계 수립을 위해서 필요하다.

Computer-Mediated Communication (CMC) based on electronic bulletin board system (e-BBS) has been widely used for various educational purposes since the advent of the Internet. Instructors can achieve pedagogical goals by analyzing the contents of postings. They can be benefited technically from analytic information on discussion activities. Studies on content analysis and social presence in communication have been traditionally done by social studies. However, researches on computational and logical analysis of the phenomenon are rare. To do that we propose a formal model to represent and analyze communication activities logically. The model consists of interactivity vector providing a formal representation of discussion activities and interactivity chart providing a graphical representation of interactivity vector. The formal approach can be used as a useful technical assistance to analyze and compare discussion groups computationally.

Korea augmentation satellite system (KASS) is the Korean satellite based augmentation system (SBAS) developed by ministry of land, infrastructure, and transport (MOLIT) since 2014. Since KASS is the safety critical system that can affect to the safety of airplane, the software of KASS is developed according to the DO178B software level induced from safety analysis. In case of KASS control station (KCS), most of the software of KCS get assigned software level E in DO178B. In that case, ECSS-Q-ST-80C category D is assigned as a software product assurance standard. In this paper, the software related standard ECSS-E-ST-40C, ECSS-Q-HB-80-04A are analyzed to satisfy ECSS-Q-ST-80C and as a result the software product assurance activities regarding software life cycle and the software quality model, metric is proposed for the product assurance of the KCS software.

E-participation is the term referring to the use of information and communication technologies to political participation by enabling citizens to connect with one another. Because e-participation systems are already constructed and operated, continuous usage is regarded as a major concern for successful e-participation. E-participation systems should guarantee ease of use, user satisfaction, and high quality. In addition, measuring the quality of e-participation systems will provide a useful strategy. This paper suggests a methodology for measuring quality of experience of the e-participation system and computing the quality score. We apply two concepts of usability measurement method and quality of experience that are most suitable. We provide the target of measurement,, the construct of quality of experience, the method of experiment and analysis of data, and the scoring method of quality of experience.

이 연구는 완전통합교육을 효과적으로 지원하기 위한 전자멘토링 시스템을 구축 및 사용성을 평가하는데 목적이 있다. 시스템 설계를 위하여 현재 운영되고 있는 국내 외 시스템과 연구들을 분석한 후, 완전통합교육 지원에 적절한 전자멘토링 수행모형을 도출했다. 특히, 설계와 구현에 있어서는 온라인의 수평적 멘토링 구현과 다양한 멘토링 형태의 지원, 상호보완적 관계형성, 그리고 활동에 대한 피드백 제공 등에 역점을 두고 시스템을 구축했다. 개발된 전자멘토링 시스템의 사용성 평가를 위해 운영자 2명, 멘토 5명, 멘티 5명을 선정한 후, '멘토링 지원(인지적 지원, 정서적 지원, 적용가능성)'과 '기술 지원(편의성, 정확성, 심미성)' 등 2가지 영역, 총 10개의 문항을 통해 심층면담을 실시했다. 통합학급 담당교사와 특수학급 담당교사의 사용성 평가 결과, 완전통합교육 지원을 위해 개발된 전자멘토링 시스템은 모든 영역에 걸쳐 상당히 효과적인 것으로 판단할 수 있었다. 향후에는 이 연구결과를 바탕으로 현장에서 장기간 지속적인 적용을 통해 개발된 전자멘토링 시스템의 실질적 효과성을 검증해 보는 연구가 요청된다.
