본 논문은 멀티미디어의 특성을 활용하여 초등학교 5학년의 음악과 전 영역을 멀티미디어 CAI로 설계하고 구현함으로써 음악에 대한 기초개념과 악곡에 대한 이해와 관심을높이고 학습자에 대한 개별학습과 교수-학습의 효율성을 높이고자 하였다. 이에 따라서 멀티미디어 CAI에 관한 이론을 탐색하고 CAI의 설계원리 및 교과의 특성을 고려하여 Hannafin와 Peck이 제안한 코스웨어 설계모형을 모델로 하였다. 설계모델에 따라 교육과정을 분석하여 멀티미디어 적용요소를 추출하였으며 저작환경에 적합한 스토리보드 형식을 작성하였다. CAI 코스웨어 설계모형에 준거하여 객체지향적이고 상호대화적인 접근을 가능하도록 멀티미디어 디렉터를 도구로 사용하였다. 본 CAI 프로그램은 멀티미디어(Text, Image, Graphic, animation, sound)를 활용하여 주의집중과 동기유발을 높혔고 특히 가창, 기악, 창작, 감상, 이론적 내용, 형성평가의 모든 음악적 영역을 교육과정의 내용에 일치시켜 충실한 교수-학습이 이루어지게 하여 모든 교사의 현장수업에 대한 부담감을 감소시켰다.

It is general that the ICAI(Intelligent Computer Assisted Instruction) consists of 4 modules. Export module, Teacher module, Student module and Interface module. In each module construction, there should be some rules to control strategies efficiently and systematically that are related to the texts and assessment instruments, assessment results and evaluation, feedback, etc. It is necessary to use a method to classify the curriculum into sections with units and to represent the identified relationships between them. These relationships are available to all the process of learning, assessment, evaluation and feedback. In this paper, we propose the method to represent these units and relationships as a graph. In addition, we implement an internet-based courseware authoring tool to support the environment in which several expert can construct concurrently the courseware with cooperation between them.

The rapid progress of IT technologies promoted the foundation to offer users 'Any Time, Any Where, Any Service', and wireless internet services made it possible to use wired internet services while traveling. The previous academic administration management system having migrated from wired to wireless was dependent on mobile equipments' platform because of not being constructed on standard surroundings. And in the aspect of faculty system, course coordinator plays an significant role in building curricula and manage them, and finally counseling students with regard to them. But the course coordinator can't afford to advise students on which fields of their faculty fit them and which courses they have to take. We propose a mobile course coordinator system to help students learn profound courses of their major fields. Also the proposed system is implemented by using JAVA and WIPI technology, so that it is platform-independent. A mobile course coordinator system has an inference engine considering not only course trees which tell informations about the courses in every fields, but also personal courses that students have taken. The inference engine calculates three weights, representing the significance of each course considering every fields, the score of prerequisite courses which a student have taken, and the suitability in which department each student fits. When students apply for taking lectures, a mobile course coordinator system recommends them the most suitable courses. A mobile course coordinator system is able to substitute for the course coordinator who is counseling students. And the students with personal cellular phone are able to keep tracking their courses, and improve their knowledge about major with taking courses which the system's inference engine will advice.

This paper studies the relationship between general investors' allotment ratio and underpricing for the companies that were newly listed in KOSDAQ market after the 20% rule, from March 2004 to December 2013, by empirical analysis. It is shown that the excess allotment ratio over 20% has a strong explanatory power for underpricing ratio under the 1% significance level. Furthermore, the general investors' allotment ratio is a significant explanatory variable of underpricing ratio under the 5% significance level. There are many hypotheses about underpricing, however, if underpricing is evident with high allocation ratio for general investors, it can be regarded as a signal of company's confidence in earnings after listing. In conclusion, this study reveals that general investors' allotment ratio can be used as a major explanatory variable that has a significant effect on the degree of undervaluation in the IPO market.

The computer subject emphasizes practice centered teaching. The materials can be used in such practice teaching play a role as resources improving poor practice teaching environment. Web courseware can be used as teaching-learning materials causing motivation and interest to learners and enabling learning activity meeting students' level and requirement. So, we developed 15 web coursewares as teaching and learning materials for middle school Computer subject in this study. The design forms of web coursewares we developed are different each other. And then, lead teachers to develope teaching and learning materials originally and to apply them to teaching variously. In addition, the practice parts of web coursewares were made of form of sham learning appling procedural simulation skill. It enables individual practice of learners, so we expect improving one to many instruction environment somewhat.

This study was carried out to investigate the offsets of pyroligneous acid on the growth of ‘Penncross’Creeping Bentgrass (Agrostis palustris Huds.) and to propose the practical use for ecologically responsive management in Korean golf courses. In the plots affected by 300, 500, and 800 times diluted pyroligneous acid, the turfgrass growth increment and the visual quality were measured at fixed periods. The data were subjected to paired samples T-test. The results summarized are as follows； 1) In leaf growth increment, density, and root spread depth, turfgrass affected by 500 and 800 times diluted pyroligneous acid were superior to the control continually. It was reliable in the statistics. Especially, 500 times diluted solutions was superior to the others. 2) In color, texture, uniformity, and recuperative strength, the visual quality of turfgrass affected by 500 and 800 times diluted pyroligneous acid were superior to the control continually. It was reliable in the statistics except the recuperative strength. Espe-cially, 500 times diluted solutions tended to be superior to the others. 3) There was no symptom of a disease in all plots. The existing management was thought to be suitable in this golf course. 500 and 800 times diluted pyroligneous acid were not thought to trigger or promote a disease, 4) After investigating the effect of pyroligneous acid on turfgrass growth, the soils of all plots were analyzed. In all plots, the chemical properties of the soils were not changed obviously. 5) Considering the results mentioned above, the practical use of 500 and 800 times diluted solutions might decrease the amount of nutrients and agricultural chemicals used in golf courses as well as promote turfgrass growth in golf courses.

의학의 발달과 산업화로 인한 생활환경의 향상은 인류에게 질병으로 인한 고통이나 사망의 위험에서 벗어나게 해 주었다. 그러나 최근 우리사회에서 일어나고 있는 대형 안전사고로 인한 사망이나 부상피해는 갈수록 높아지고 있다. 이는 사회 전반에 퍼져있는 안전의식의 결여가 낳은 결과로, 사고를 사전에 예방하고, 사고로 인한 인명피해를 줄이기 위해서 모든 국민은 안전교육의 중요성을 인지하고, 교육의 활성화를 위해 노력해야 한다. 특히, 감수성이 예민하고 지식이나 가치관, 태도의 형성과정에 있는 어린이들에게 안전의식을 체계적으로 형성하고 관련지식을 갖도록 하는 것은 중요하다. 일선 학교 교사들도 안전교육의 필요성은 느끼지만, 교육적으로 활용할 수 있는 자료는 많이 부족한 실정이다. 이에 본 연구에서는 초등학생을 위한 안전교육 코스웨어를 연구하여 이를 아동들이 언제 어디서나 웹을 통하여 학습할 수 있는 장을 마련함으로써 아동들에게 안전에 대한 경각심과 안전의식을 심어주는데 목적이 있다.
