The demand for cyber education in Korea is constantly increasing and the need for research on online lecture on contents design that increases the learning effect is rising. In this research, the online lecture contents about the technical information type provided by Korea Cyber University was understood and we researched about the most preferred lecture type and the most effective lecture type in learning among the 1,173 students in Korea Cyber University who participated in this online survey. Also, we analyzed if the students' preference for the lecture type depended on their experience on that lecture type and we studied the students' claims postulated on the interface design of the lecture contents. The most preferred lecture type among students was e-Stream+flash and they answered that multi-media type lectures were the most effective lectures in learning. The majority of the students preferred lecture contents that they have experienced before and preferred the menu on the left side of the page in interface design. Not only the completeness, but the applications in design in lecture contents are also an important factor in online lectures. As the demand for cyber education in Korea is increasing, content design that can increase the academic performance should be further researched.

This research was conducted in order to know how influential the acknowledgment of factors such as the quality of educational contents and the conducting of off-line lectures is in terms of effective learning for leaners. Based on the satisfaction-importance model of the multi-attribute attitude model, this study would like to clarify the degree to which the quality of on-line contents of on-line education and the simultaneous conducting of off-line lectures influences one's learning attitude. On-line contents satisfaction will evaluated through the three categories: audio lectures, video lecture and WEI lectures, which make up the quality of on-line contents. We would also like to do a survey on the transformation of learning attitudes when on-line and off-line lectures were conducted simultaneously.

동영상, 음악, 카메라영상, 음성 등 다양한 객체를 결합하는 강의 제작기는 강의 콘텐츠 제작에 유용하다. 본 프로그램은 다양한 객체를 결합하여 무 손실 압축 처리한 강의 콘텐츠를 제작한다. 결과물로서 음성/영상/인덱스의 3가지 종류의 파일이 생성된다. 인덱스파일은 영상 정보, 영상 파일 구성정보, 음성정보, 음성파일 구성정보를 가지며 음성파일은 각 객체의 음성만을 interpolation 처리 후 하나의 데이터로서 혼합한 결과물이다. 영상 파일은 영상 정보만을 결합한 뒤 wavelet, motion estimation, 사전코드 방식과 huffmancode 방식을 혼합한 방식을 응용한 무 손실 압축 영상데이터 이다.

본 연구의 목적은 사이버대학의 성과에 영향을 미치는 서비스 특성화 요인을 찾는 것이다. 본 연구에서는 사이버대학의 성과를 교수, 졸업 및 취업, 브랜드 이미지 측면에서 접근하였고, 선행연구를 토대로 하여 사이버대학의 성과에 영향을 미치는 서비스 특성화 요인으로 콘텐츠 다양성, 콘텐츠 품질, 콘텐츠 실무지향성, 강의 실재감, 학습관리를 도출하였다. 연구모형을 검증하기 위해 중국의 사이버대학에 재학 중인 대학생들을 인터넷 설문을 배포하여 총 170부의 유효설문을 수집하여 실증 분석하였다. 실증 분석한 결과, 다음과 같은 다섯 가지의 연구결과를 확인하였다. 첫째, 콘텐츠 다양성 수준이 높을수록 사이버대학의 성과는 높아지는 것을 확인하였다. 둘째, 강의 콘텐츠 품질이 우수할수록 사이버대학의 성과는 높아지는 것을 확인하였다. 셋째, 콘텐츠 실무 지향성이 높을수록 사이버대학의 성과가 높아지는 것을 확인하였다. 넷째, 강의 실재감이 높을수록 사이버대학의 성과는 높아지는 것을 확인하였다. 다섯째, 학습관리 수준이 높을수록 사이버대학의 성과가 높아지는 것을 확인하였다.

In this study, we examine the satisfaction and dissatisfaction factors on the perceptions of online lecture content among open and distance university learners, especially focusing on age groups differences. The result of the study shows that clear differences exist between age groups in regards to the factors which insure excellent course in online learning. For example, young adults in their 20s and 30s determined 'useful for practical life, 'screen sensitive to audiovisual', and 'recently created lectures' as the most influential factors for online learning content satisfaction. However, older age groups in their 40s and above apparently showed a high preference for factors such as 'instructor's enthusiasm and attitude', and 'clear and easy-to-understand explanations.' The findings of the study imply that learners' recognition concerning content satisfaction may differ depending on age groups. Moreover, this study suggests that considering the growing importance of online learning in relation to the COVID-19 pandemic, age groups should be considered in developing online course content.

Many kinds of the education systems are provided to students. Many kinds of the contents like School subjects, license, job training education and so on are provided through many kinds of the media like text, image, video and so on. Students will apply the knowledge they learnt and will use it when they learn other things. In the existing education system, there have been many situations that the education system isn't really helpful to the students because too hard contents are transferred to them or because too easy contents are transferred to them and they learn the contents they already know again. To solve this phenomenon, a method that transfers the most proper lecture contents to the students is suggested in the thesis. Because the difficulty is relative, the contents A can be easier than the contents B to a group of the students and the contents B can be easier than the contents A to another group of the students. Therefore, it is not easy to measure the difficulty of the lecture contents. A method considering this phenomenon to transfer the proper lecture contents is suggested in the thesis. The whole lecture contents are divided into many lecture modules. The students solve the pattern recognition questions, a kind of the prior test questions, before studying the lecture contents and the system selects and provides the most proper lecture module among many lecture modules to the students according to the score about the questions. When the system selects the lecture module and transfer it to the student, the students' answer and the difficulty of the lecture modules are considered. In the existing education system, 1 kind of the content is transferred to various students. If the same lecture contents is transferred to various students, the contents will not be transferred efficiently. The system selects the proper contents using the students' pattern recognition answers. The pattern recognition question is a kind of the prior test question that is developed on the basis of the lecture module and used to recognize whether the student knows the contents of the lecture module. Because the difficulty of the lecture module reflects the all scores of the students' answers, whenever a student submits the answer, the difficulty is changed. The suggested system measures the relative knowledge of the students using the answers and designates the difficulty. The improvement of the suggested method is only applied when the order of the lecture contents has nothing to do with the progress of the lecture. If the contents of the unit 1 should be studied before studying the contents of the unit 2, the suggested method is not applied. The suggested method is introduced on the basis of the subject "English grammar", subjects that the order is not important, in the thesis. If the suggested method is applied properly to the education environment, the students who don't know enough basic knowledge will learn the basic contents well and prepare the basis to learn the harder lecture contents. The students who already know the lecture contents will not study those again and save more time to learn more various lecture contents. Many improvement effects like these and so on will be provided to the education environment. If the suggested method that is introduced on the basis of the subject "English grammar" is applied to the various education systems like primary education, secondary education, job education and so on, more improvement effects will be provided. The direction to realize these things is suggested in the thesis. The suggested method is realized with the MySQL database and Java, JSP program. It will be very good if the suggested method is researched developmentally and become helpful to the development of the Korea education.
