The purpose of this second one of the two consecutive papers, which carried out for the research, is to evaluate their relative effectiveness regarding instruction with such three presentation methods as video/print+ lecture, print/video, print+lecture/video, with which the library of Duk Sung Women's University applied already for the orientation of the freshmen in 1988. In sum, the major research findings are as follows : First, as the more numerous media were applied for the orientation, the instruction were more effective. Second, it is very interesting to find out that there were wide differences in effectiveness among the three presentation methods applied for the student. Especially, the print+ lecture/video method was more effective in the instruction than the print/video method. Surprisingly, the video/print + lecture method was much more effective than the print+ lecture/video method. With the research findings of this two consecutive papers into consideration, it seems safe to say that the video-tape method was most effective among such three orienting methods as lecture, slide-tape, and video tape, and the video/print+lecture method was most effective among such three presentation methods as video/print+lecture, print/video, and print+lecture/video.

Objective: This study aims to implement a non-contact gesture-based interface for presentation purposes and to analyze the effect of the proposed interface as information transfer assisted device. Background: Recently, research on control device using gesture recognition or speech recognition is being conducted with rapid technological growth in UI/UX area and appearance of smart service products which requires a new human-machine interface. However, few quantitative researches on practical effects of the new interface type have been done relatively, while activities on system implementation are very popular. Method: The system presented in this study is implemented with KINECT$^{(R)}$ sensor offered by Microsoft Corporation. To investigate whether the proposed system is effective as a presentation support tool or not, we conduct experiments by giving several lectures to 40 participants in both a traditional lecture room(keyboard-based presentation control) and a non-contact gesture-based lecture room(KINECT-based presentation control), evaluating their interests and immersion based on contents of the lecture and lecturing methods, and analyzing their understanding about contents of the lecture. Result: We check that whether the gesture-based presentation system can play effective role as presentation supporting tools or not depending on the level of difficulty of contents using ANOVA. Conclusion: We check that a non-contact gesture-based interface is a meaningful tool as a sportive device when delivering easy and simple information. However, the effect can vary with the contents and the level of difficulty of information provided. Application: The results presented in this paper might help to design a new human-machine(computer) interface for communication support tools.

Synchronizations of intra${\cdot}$intermedia for the lecture presentation in distributed multimedia environments are difficult to guarantee accurate temporal relationship between media, due to the asynchronous errors such as the delay or loss of transferred data or the transmission characteristics of each media. The jitter phenomenon occurs when the network delay has the media arrival rate abnormal because the intra-media synchronization reflects the presentation rate. And the cumulative effective of jitters on a per media stream basis results in a skew. This phenomenon cause confusion to contents recognition of learners due to network delay and can not provide effective interaction of sender and receiver in the distance education. Therefore, this paper can be solution to problems due to network delay by maintaining the requirements of temporal relationship between more than one media. And this paper enables to suggest the inter-media synchronization method that is subject to be influenced by presentation rate, and to implement lecture presentation system for distance education.

It is important to consider not only audio/video but presentation way, in video conferencing, seminar, lecture based network communication. The method to transmit image of a chalkboard used in traditional seminar, conference, lecture are one of difficulties for remote environment since it requires techniques high-resolution transmission and talking films. In this paper we implemented real-time multimedia shared board system for shared effective multimedia presentation using connection-oriented socket of TCP. In this system, decreasing cost of related system construction, improve of data reliableness and interaction, presentation delay time be able to minimize.

This study investigated the degree of knowledge achievement and self-confidence in aseptic technique as a part of the fundamental nursing practice classes. The subjects were 220 nursing students in a junior college in Chonnam and an applied Quasi-experimental research methodology was used thirty of them comprised an experimental group to examine learning according to the teaching method. Wata were collected over 80 days, from April to June 1988, analyzed using descriptive statistics, percentages, means, t-test, one way ANOVA, Pearson's correlation coefficient and stepwise multiple regression with the SAS program. The conclusions are as follows. 1. The mean score of the degree of knowledge achievement of aseptic technique of the 220 students was 0.68(possible score 1.0) before the lecture but was 0.88 after lecture(p=.000). 2. The mean score for aseptic technique of the 220 students was 3.41(possible score 5.0) before practice but was 4.27 after practice(p=.000). 3. The correlation of self-confidence before and after practice was relatively low(r=.25, p=.000). 4. The mean score of the degree of knowledge achievement of aseptic technique in the experimental group(selected 30 students) was 0.72 before the lecture but was 0.90 after the lecture. 5. The mean score of self-confidence on aseptic technique in the experimental group(selected 30 students) was 3.18 before practice but was 4.32 after practice(p=.000). 6. The mean score of learning according to the type of teaching to aseptic technique for the experimental group(selected 30 students) was 23.2(possibel score 34) after lecture and presentation, was 27.3 after learning through video tape, was 31.7 after presentation through practice, was 33.7 after first practical training, and was 34 after secondary practical training.

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.

Dr. Corley had various experiences as an outstanding structural engineer. His experience as the chief investigator for the collapse of World Trade Center and Oklahoma city building was so much useful to the lecture. His presentation had covered 3 different collapsed buildings like Oklahoma city, Pentagon and World Trade Center. He had shown to the audiences 2 videos and 76 slides by power point. The learned lessons from his presentation were: 1. The appropriate Building Code is very important. 2. The sound details are very important for the structure to resist the extreme outer force. 3. The continuous diagnosis and maintenance of the structure is important. 4. The reasonable attitude of the government against the accident is important. 5. The professional engineer must take a main role as a guard for the safety of the people.

When you present a medical scientific paper or give a lecture in English, It is important to visit your presentation room in advance to gain familiarity with the controls and the computer. You can check how to use the mouse or laser pointer and determine where the microphones are. You should meet the Chairman and introduce yourself. You may ask the Chairman any questions you have. I am confident this strategy will work for beginners because they are usually nervous before their presentations. Most Chairmen prepare one or two questions for the presenters to stimulate discussion. Speaking with the Chairman also allows you to determine the type of English that he or she speaks (i.e., French-English, Spanish-English, and British-English). You need to be comfortable with the Chairman's English before the presentation because the Chairman will repeat the questions for you when you do not understand a question from the audience. Although I have given a number of lectures and moderated many scientific sessions and symposiums in English over the past 20 years, it is still difficult and stressful for me to do these in English because English is not my first language. To overcome the problems, I have written down the questions and useful English expressions that I have received during or after my presentation because I found them helpful for my next presentation. I hope the examples will be of great help to you.
