I studied a distance education model for English learning on the Internet. Basic WWW files, that contain courseware, are constructed with HTML, and functions, which are required in learning, are implemented with Java. Students and educators can access the preferred unit composed of the appropriate text, voice and image data by using a WWW browser at any time. The education system supports the automatic generation facility of English problems to practice reading and writing by making good use of the courseware data or various English text resources located on the Internet. Our system has functions to manage and control the flow of distance learning and to offer interaction between students and the system in a distributed environment. Educators can manage students' learning and can immediately be aware of who is attending and who is quitting the lesson in virtual space. Also, students and educators in different places can communicate and discuss a topic through the server. I implemented these functions, which are required in a client/server environment of distance education, with the use of Java. The URL for this system is "http://park.taegu-e.ac.kr" in the name of GAIA.

This study proposed an SCA advice system. It is an ontology-based recommender that provides advice on appropriate computer curricula based on the behavior of high school students. The three computer curricula at Chiang Mai Rajabhat University include computer science (CS), information technology (IT), and web programming and security (WEB). This study aims to design the ontology framework for an SCA advice system. The system considers three core ontologies: student, computer-curriculum, and advice. After analyzing student behaviors, the behavior types of CS, IT, and WEB were determined to be SB-2, SB-1, and SB-5, respectively. All subjects in these three curricula were analyzed and grouped into seven groups. Their curricula were synthesized in terms of basic skills, basic knowledge, and characteristics. Finally, advice results can be obtained by consolidating the curriculum nature of the CS, IT, and WEB curricula.

A brain-computer interface (BCI) is a communication system that translates brain activity into commands for computers or other devices. In other words, BCIs create a new communication channel between the brain and an output device by bypassing conventional motor output pathways consisting of nerves and muscles. This is particularly useful for facilitating communication for people suffering from paralysis. Due to the low bit rate, it takes much more time to translate brain activity into commands. Especially it takes much time to input characters by using BCI-based typewriters. In this paper, we propose a brain-operated typewriter which is accelerated by a language prediction model. The proposed system uses three kinds of strategies to improve the entry speed: word completion, next-syllable prediction, and next word prediction. We found that the entry speed of BCI-based typewriter improved about twice as much through our demonstration which utilized the language prediction model.

대부분의 대학생들은 재학기간 중에 학교에서 운영되는 교육프로그램, 자원봉사, 어학연수, 동아리활동 등 다양한 경험을 하게 된다. 최근에는 학교에서 운영하는 교육프로그램이 더욱 다양해지고 많은 학생들이 참여하고 있다. 하지만 학교에서는 학생들이 어떤 활동을 했는지 효율적으로 관리하고 참여 학생의 적극적인 참여율 유도가 필요가 있지만, 이를 효율적으로 관리하는 것은 어려운 일이다. 본 연구는 학교에서 시행중인 다양한 프로그램들에 대하여 학생들이 참여함에 따라 학생들의 참여현황을 조사하여 관리하고 참여율과 학과별 통계를 Dashboard로 열람할 수 있는 프로그램을 개발하여 운영하였다. 교육 참여 관리 시스템을 활용함으로써 담당자의 업무 효율을 기대할 수 있고 체계적인 학생들의 교육 프로그램을 효율적으로 모니터링하고 관리할 것으로 기대된다.

In recent years. XML applications are being developed in diverse area. Especially, development of XML document repository system associated with database is carrying out widely. The previous researches of XML repository system have several defects which are update and retrieval limitations for the XML document, design limitation for a formal retrieval algorithm and data redundancy. In order to solve the above problems. in this paper, we suggest relational database schemes for overcoming limitations of updating, retrieving, and rebuilding document. And suggest query translation strategy using two-phase translation that consists of pattern analyzing phase and SQL generating phase.

While welcoming the distributing of the powers of the Ministry of Education, which is currently being promoted, to the city and provincial offices of education, I am very concerned that this will expand and amplify the powers concentrated in one central institution to 17 local institutions closer to the field. Until now, the Ministry of Education and the Office of Education have served as co-cause providers as important reasons for hindering school education. The transfer of the authority of the Ministry of Education is highly likely to be deformed as soon as it results in the quantitative reduction of the functions and roles of the existing Ministry of Education and the quantitative expansion of the roles and functions of the city and provincial offices of education. In the reality that no legal device for school autonomy has been established, it is highly likely that emphasizing the principle of school autonomy in our educational climate, which is deeply rooted in the vertical bureaucratic administrative culture, will end with a simple measure or stop at the level of imitation. Therefore, a more stable device is needed to check the authority of the city and provincial office of education and the superintendent of education to take over the authority of the Ministry of Education. This is also a system that is still required even when school autonomy becomes legal. Therefore, it is necessary to revitalize the independent education committee, establish a local education committee in the city and province education office, and activate the resident participation system (resident proposal system, resident voting system, resident litigation system, resident audit request system).

This paper addresses the issue of design and application of a Web-based counseling system of which purpose is to facilitate counseling so that students can freely express their personal problems and get professional helps through the system. The prominent features of the counseling system are that the system encourages students to involve actively in interactive process, and it helps them to create genuine interests out of disbelief or uneasiness towards counseling, and it helps them to create positive attitude towards counseling. To do that, counseling process should meet the requirement of confidentiality in order to build trust between counselor and counselee. Many counseling sites operated by various organizations utilize E-mail as a communication channel for confidentiality purpose, which is likely to end up with single occasions in which desirable relationships for counseling can hardly be established. To solve the above-mentioned problem, a closed, confidential, Web-based counseling system was built on a Web server so that trustful relationship can be accomplished through a confidential, Web-based counseling system. Also, the result of applying it to a local elementary school is stated. Thanks to the merits of personalized, confidential counseling system compared to the face-to-face counseling, surpassing the limitation of time and space and overcoming the fearfulness, it was well observed that students showed great interests in participation of conseling.

The purpose of this study is to design and develop the e-mentoring system which supports the effective information education and to evaluate the usability of the system. Through literature reviews of related studies, an effective e-mentoring performance model was drawn. An e-mentoring system was designed and developed based on the model. 237 middle school students who had participated in e-mentoring for the information education evaluated the usability of the system. As a result of it, the system was considered good in both category(supporting mentoring(M=3.63), technology(M=3.78). The means of subcategories of 'supporting mentoring'(instructional easiness, psychological safety, and adaptability) were scored 3.65, 3.30, 3.43 respectively. And means in the subcategories of 'technology'(usefulness, accuracy, and look & feel) were 3.90, 3.64, and 3.73. It can be concluded that the e-mentoring system developed in this study was effective in mentoring information education.
