In engineering education practical experiments is very important for each student, but due to the limitation of time and available resources such as laboratory equipment, space and instructors enough hands-on real experiments could not be provided to all students enrolled in the program throughout the academic year. In this sense web-based remote experiments through internet become a solution for engineering education and an emerging new paradigm for students and teachers. This paper presents the development of the web-based remote vibration experiment system for mechatronics education. Students can access this experimental equipment through an internet and conduct vibration experiment remotely without any restriction on time and place. IP address for data communication and web-service are assigned in local computer and then students receive experimental results and the captured pictures using network. The developed system provides real-time feedback of the tested results. Ubiquitous access to the system gained popularity from students.

The research method consisted of procedures in parallel with literature analysis and expert meetings. As for the contents of the study, a composition system that recognized the problems and solutions of lifelong education for the developmental disabled based on universities was primarily presented. Through this, it was suggested that universities can form an academic foundation for the establishment of a lifelong education support system for the developmental disabled along with the convergence field. In addition, a structural model related to this was presented along with the aspect that universities could develop a curriculum for lifelong education for the developmental disabled according to the school foundation. Also, a composition system was suggested that universities can develop lifelong education curriculum for people with developmental disabilities to lead the cooperation of local related organizations such as welfare centers for the disabled and lifelong education centers for the developmentally disabled. As a result of the study, it was analyzed that leadership in the university-based lifelong education support system for developmental disabled can contribute to fostering professional manpower qualifications and establishing cooperation with local related organizations in an integrated composition system.

The rapid development of information and communication technologies has resulted in rapid increase in the qualitative and quantitative information that can be accessed by information technology. Furthermore an enormous amount of information is provided in various formats. However, there are a group of people who are not able to even approach to targeted information due to physical or environmental problems. Visually handicapped users constitute a class of these users. In this paper, a method of developing user interface for web-based education service is described for the visually handicapped users to access information more efficiently. First, this paper analyzed the problems of visually handicapped users to access information targeting representative domestic sites that supply education services. And based on the results of the above analyses, Nest, this paper explains the web-based education service interface implementation method according to types of the content to be delivered. Lastly, the validity of this method is provided by testing a web page based on the implementation method according to the types of content.

Moving object segmentation from a nonstationary camera is a difficult problem due to the motion of both camera and the object. In this paper, we propose a new confidence-based background subtraction technique from moving camera. The method is based on clustering of motion vectors and generating adaptive multi-homography from a pair of adjacent video frames. The main innovation concerns the use of confidence images for each foreground and background motion groups. Experimental results revealed that our confidence-based approach robustly detect moving targets in sequences taken by a freely moving camera.

정보통신기술의 발달로 교육환경에서도 많은 변화가 일어나 ICT 활용 교육을 통한 다양한 형태의 교수 학습 유형이 논의되고 있으며 최근에 급격히 발달하고 있는 인터넷을 활용한 원격교육이 급격히 확산되고 있는 실정이다. 하지만 교사가 일방적으로 과제를 제시하고 학생들은 인터넷 사이트를 활용하여 정보를 수집하여 가공하는 보여주기식에 그쳐 학생간 교사간의 상호작용이 부족하여 인터넷 활용 학습의 장점을 살리지 못하고 있다. 이에 본 연구에서는 웹과의 통합적 또는 보완적 차원에서 가장 적합하다고 여겨지는 구성주의의 문제중 심학습 이론을 기반으로 하여 화상통신기술을 활용한 문제중심학습 환경을 구현하고 초등학교 현장에 적용하여 그 결과를 분석하였다. 그 결과 교사와 학습자간 학습자 동료 집단간의 상호작용에 효과가 있었으며 학습자의 수업에 대한 참여 태도 및 흥미, 집중력에 긍정적인 효과를 가져왔다. 또한 면대면 학습에서 부족했던 부분을 사이버 학습을 통해 보완할 수 있었으며 문제중심 학습모형의 장점을 살릴 수 있었다.

A field determination method for small D-T neutron source yield based on the oxygen prompt gamma rays was established. A neutron-gamma transport equation of the determination device was developed. Two yield field determination devices with a thickness of 20 mm and 50 mm were made. The count rates of the oxygen prompt gamma rays were calculated using three energy spectra processing approaches, which were the characteristic peak of 6.13 MeV, the overlapping peak of 6.92 MeV and 7.12 MeV, and the total energy area. The R-square of the calibration curve is better than 94% and the maximum error of the yield test is 5.21%, demonstrating that it is feasible to measure the yield of D-T neutron source by oxygen prompt gamma rays. Additionally, the results meet the requirements for field determination of the conventional D-T neutron source yield.

This article describes the current status of site-based environmental education (EE) in the Republic of Korea. Implications for site-based EE program development and operation are presented and recommendations for an improvement are provided. Questionnaires were mailed to 205 schools and organizations where site-based EE programs operated in 2002 with funding from the Korean Ministry of Environment. The questionnaire was designed and used to examine the scope, operation, and needs of site-based EE programs. The response rate was 27.3%. The results of the survey indicated that 'awareness', 'participation', and 'attitude' were addressed by the program goals and objectives more than 'knowledge' and 'skills'. The survey also indicated that activities in the programs were not variable and most were teacher/instructor-centered. Most of the programs reflected the 'connection with everyday life, direct experience and sensitivity'. There were some difficulties in motivating students and finding a good location and qualified instructional staff. Needs included well-designed program development and dissemination, professional development, increased funding support, and more effective program evaluation.

The purpose of this study was to evaluate site-based environmental education(EE) programs. For the evaluation, an evaluation chart was developed. The chart was consisted of twenty evaluation items in the following six categories : 'goals & objectives', 'instructional planning', 'instruction', 'learning outcomes & evaluation', 'features of program', and 'program operation'. One hundred sixty five site-based EE programs, funded by the Korean Ministry of Environment in 2000, were evaluated. After the evaluation, the programs were also categorized and analyzed according to regions, organizations, and amount of funds. The results indicated that awareness, participation, and attitude were addressed in the purpose of the programs, while knowledge and skills were not. The diversity of activities and teaching strategies of the programs were insufficient. Cultural aspects, fairness, originality, and accuracy were also insufficiently addressed. Assessment and evaluation of such programs were needed to be considered to a larger degree. From the analysis of programs according to categories, Choongbuk province in the regional aspect and schools in the organizational aspect got higher scores than others. Overall, the more funding the program received, the higher score it got in evaluation. Some improvements and strategies for activating site-based EE were recommended based on the result of the evaluation.
