The contents of remote lectures are written by authoring tools or animation tools. Written contents then integrate existing medias, and are stored in a file type, which is added to the lecturing activities of lecturers. These files are stored according to the kinds of each authoring tool. So, there is no interchangeability and the efficiency of each media is not so good. Due to these structural features, it is not possible to do streaming lectures in on-line environments. In this study, a technique was suggested, which guarantees the interchangeability of remote lecturing contents using SMIL which is a synchronizing multimedia language. The suggested technique is an extended type of SMIL, and includes tags to represent the lectures of tutors which are the specific feature of remote lectures. Additionally, a model, which does streaming SMIL remote lecture contents through on-line, and which transfers control techniques are suggested. The remote lecture contents established by the proposed method can be applied to all authoring tools for remote lectures just by installing conversion modules, and can be a kind of expression model of the synchronizing model for streaming service in on-line environment.

Multiple-choice survey types have been mainly performed to analyze students' needs for online classes. However, in order to analyze the exact needs of students, unstructured data analysis by answer for essay question is required. Big data is applied in various fields because it is possible to analyze unstructured data. This study aims to investigate and analyze what students want subjects or topics for software lecture in general education that process on non-face-to-face online teaching methods. As for the experimental method, keyword analysis and association analysis of big data were performed with unstructured data by giving a subjective questionnaire to students. By the result, we are able to know the keyword what the students want for software lecture, so it will be an important data for planning and designing software lecture of liberal arts in the future as students can grasp the topics they want to learn.

As the number of the deaf who go out into the society has been increasing, in most of the lectures, the demands for the sign language interpretation and the accuracy of the interpretation have become more important. Especially, in order to improve the accuracy of the sign language interpretation, the interpreter must be aware of the appearances of the lecturer and the contents of the lecture, and at the same time, the interpreter must look toward the audience. This research introduces a system which can be effective in a small classrooms or auditorium, by providing the maximum information about the lecturer and the contents of the lecture. Also, in order to verify the effectiveness of the proposed system, this research includes the discussions about the related systems and test methods. In conclusion, delivering the images of the lecturer and the contents of the lecture to the interpreter by employing the proposed system has been proved effective.

This paper presents web-based contents for studying electrical machines using Java Bean and Flash. The component-based software development techniques have been used to develop Java Bean and Flash components which are simple and convenient for learners. The components have been used to make 61 contents for the electrical machines. The contents have highly interactive capability, which gives much interest to learners. The learners can easily understand the electro-mechanical concept by changing the parameters interactively. The class load of the lecture can be reduced because the basic explanation of the subject is replaced by the web contents. The better quality of the class is expected by dealing with the higher concept in the classroom lecture because the basic concepts are explained through the contents.

The purpose of this study was to analyze the contents of the sound environment among the various environmental factors that directly or indirectly affect the quality of education through the remodeling of the small hall of the College of Humanities at W University. Before remodeling into a lecture room, the small hall of the College of Humanities at W University, which is the subject of this study, was designed to create an indoor sound environment suitable for a lecture room by recognizing differences in acoustic performance between the performance halls that require adequate sound quality and the lecture rooms where the clarity of voice is important. Therefore, this study aimed to present examples of improved acoustic performance in lecture rooms by remodeling through the stages of measuring acoustic performance before remodeling, presentation of a change in finishing materials through sound simulation, and measurement of sound performance after remodeling. It is expected that this process can be used as an example of securing indoor acoustic performance suitable for educational space, such as lecture rooms, by changing the finishing materials.

In this paper, we developed an online lecture for digital logic circuit which is a basic course in electric/electronic education. Because of importance of the laboratory experiences in this course and to reflect industrial requests, we have selected most effective experimental examples in each chapter and inserted instructions for basic usags of ORCAD and digial clock design. Moreover, we developed cyber lab to design students' own circuit using Flash animation. Two features of this cyber lab are real-like graphics for devices and breadboards to improve reality and patented new IC chip objects for easy experiments, which help the students understand digital logic easily.

The scope ID field of IPv6 multicast address indicates the zone of the destination for which a multicast traffic is intended. Without any further examination on the header field, the scope ID enables a router to determine whether the traffic will be forwarded to a subnet or not. For the graceful migration from IPv4 networks to IPv6 networks, various IPv6 applications working through IPv4 networks are indispensable during the migration period. This paper describes development of an interactive remote lecture system providing service integration on voice, image, and data of teaching materials. Access right to the network for dialog among multicast group members is controlled via additional TCP (Transmission Control Protocol) session. A jitter buffer algorithm was implemented to improve the voice communication jitters.
