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.

한국과 미국(North Carolina주)의 확률과 통계 교육 내용을 고찰한 결과 한국과 미국(North Carolina주)은 내용적인 면에서 많은 차이를 보였다. 한국의 경우, 9-가 단계와 10-가 단계, 선택과목 중 수학 I, 실용수학, 이산수학 과목에 제시되어 있는 확률과 통계 영역은 심화선택과목인 확률과 통계 과목의 내용을 축소하여 재구성한 내용을 제시하고 있다. 미국(North Carolina주)은 한국과는 달리, Introductory Mathematics, Algebra(I, II), Technical Mathematics(1, 2) Advanced Mathematics, Advanced Placement Calculus, Discrete Mathematics, Integrated Mathematics(1, 2, 3), Geometry 과목에서 확률과 통계 영역은 각 과목과 연관성 있는 내용으로 구성되어 있다. 한국의 심화 선택과목인 확률과 통계 과목과 미국(North Carolina주)의 AP통계(Advanced Placement Statistics)를 비교한 결과, 전체적으로, 자료의 정리, 확률변수와 확률분포 영역에서 한국과 미국(North Carolina주)은 거의 유사성을 보이고 있지만, 통계적 추론에서는 미국(North Carolina주)이 한국에 비하여 강화되어 있음을 알 수 있다.

기존의 점수와 석차로서 학생을 평가하여 발생하는 문제점을 해결하기 위하여 서술식의 성적평가가 도입되고 있다. 그러나, 이 서술식으로 이루어지는 성적 평가는 업무를 증가시키고 또 교사의 주관적인 성적평가로 인해 성적처리의 일관성이 유지되기 어려운 문제점이 있다. 본 논문에서는 교사가 학생의 성적을 효과적으로 평가하기 위하여 퍼지 추론을 이용한 서술식 성적평가 시스템을 제안한다. 사용자(교사)로부터 수행평가요소의 결과와 과목의 최종적인 평가를 퍼지 추론에 적용하여 객관적인 성적평가를 한 후, 추론규칙의 적합도를 이용하여 성적평가 문장을 추출하여 서술식 평가 문장을 생성하도록 한다

IT 관련 기술의 발전은 'Any Time, Any Where, Any Service'를 사용자에게 제공할 수 있는 제반 여건을 마련하였다. 기존 웹 기반의 학사정보 시스템에서는 사용자의 이동성이 제한적이었고, 이를 해결하고자 한 무선 인터넷 기반의 학사정보 시스템은 클라이언트의 어플리케이션이 표준화된 환경에서 구축되지 않아서 모바일 기기의 플랫폼에 종속적이었다. 또한, 선택과목이 많은 학부제에서는 코스 코디네이터의 역할이 매우 중요하지만, 코스 코디네이터의 역할을 하는 지도교수와 학생 간의 커뮤니케이션의 부족으로 학생들은 도움을 받기 어렵다. 본 논문에서는 JAVA와 WIPI를 이용하여 플랫폼에 독립적이며 전공분야의 중요과목을 추천해 주는 과목 추천 시스템을 제안한다. 과목 추천 시스템은 학생들에게 수강과목에 대해 조언을 해 주는 코스 코디네이터의 역할을 대신할 수 있을 것이다. 또 학생들은 언제 어디서나 개인 휴대폰을 이용하여 수강신청에 관한 학사정보를 관리할 수 있고, 시스템의 추론에 따른 추천 과목을 수강하여 전공 분야에 대한 깊은 지식을 갖출 수 있을 것이다.

The interest in artificial intelligence is due to an increase in influence on companies, organizations, daily lives and society. The purpose of this study is to analyze the key elements in the teaching subjects of artificial intelligence-related subjects of Korean universities based on the intelligent system area of Computer Science 2013 in terms of human resources development. According to the analysis, there are five out of nine universities that run the required courses. Based on the 12 detailed knowledge domains of intelligent systems, the compulsory subjects of universities are distributed in the field of basic search theory, basic knowledge expression and reasoning, and inference based on uncertainty. The elective courses of each university covered topics in five to eight areas of the total knowledge area of the intelligent system, with 69.9 percent of universities with the highest average ratio of areas involving the subject of teaching subjects and 46.3 percent of universities with the lowest. This study has implications for the fact that prior to entering an artificial intelligence graduate school, we were able to grasp the level of knowledge about artificial intelligence at the undergraduate level.

The descriptive grade evaluation system is adopting to solve the problems of pre-exiting system that refers to marks and ranks. However, it increases the work load and creates inconsistencies of the grade evaluations due to teachers subjective evaluations. In this Paper, I suggest a grade evaluation system, applying the Fuzzy reasoning on web for teachers to evaluate students more effectively. Teachers can input the results of the accomplishment assessments. It also evaluates with the Fuzzy reasoning to attain the final evaluation of the subjects. The system also creates descriptive evaluation sentences by abstracting some sentences for evaluation utilizing the properties of the Fuzzy reasoning rules.

In the aspect of the faculty, a course coordinator plays an significant role in managing the curriculum and counseling students on academic matters and fostering their progress in the course. However, the course coordinator cannot afford to advise students on which fields of their faculty fit them and which courses they have to take. This paper proposes a mobile course coordinator system to help students learn courses of their major fields deeply. Also the proposed system is implemented by using WIPI technology, so that it is platform-independent and it is able to assist the course coordinator who is counseling students. And the students with personal cellular phones are able to keep tracking their courses, and improve their knowledge about major subjects by taking courses which the system's inference engine will advise.

The study uses department of the sensitivity and fuzzy reasoning, one of artificial intelligence algorithms, so that develop LED lighting system based on fuzzy reasoning for systematical control of the LED color temperature. In the area of sensitivity engineering, by considering the relation between color and emotion expressed as an adjective word, the corresponding sensitivity word can be determined, By taking into consideration the relation between the brain wave measured from the human brain and the color temperature, the preferred lesson subject can be determined. From the decision of the sensitivity word and the lesson subject, we adjust the color temperature of RGB (Red, Green, Blue) LED. In addition, by using the information of the latitude and the longitude from GPS(Global Positioning System), we can calculate the on-line moving altitude of sun. By using the sensor information of both temperature and humidity, we can calculate the discomfort index. By considering the altitude of sun as well as the value of the discomfort index, the illumination of W(white) LED and the color temperature of RGB LED can be determined. The (LED) sensitivity lighting control system is bulit up by considering the sensitivity word, the lesson subject, the altitude of sun, and the discomfort index The developed sensitivity lighting control system leads to more suitable atmosphere and also the enhancement of the efficiency of lesson subjects as well as business affairs.
