Due to the recent pandemic, most educational systems are being conducted through online classes. Unlike face-to-face classes, it is even more difficult for learners to maintain concentration, and evaluating the learners' attitude toward the class is also challenging. In this paper, we proposed a real-time concentration-based review support system for learners in real-time video lectures that can be used in online classes. This system measured the learner's face, pupils, and user activity in real-time using the equipment used in the existing video system, and delivers real-time concentration measurement values to the instructor in various forms. At the same time, if the concentration measurement value falls below a certain level, the system alerted the learner and records the timestamp of the lecture. By using this system, instructors can evaluate the learners' participation in the class in real-time and help to improve their class abilities.

The purpose of this study is to investigate whether there is a difference in the effect of learning flow and teaching presence according to the lecturer's appearance and students' behavioral patterns in video learning. For this experiment, 183 freshmen from Xingtai University in China were selected as subjects. After being classified according to DISC, students were assigned to study the lecture videos with the appearance of the lecturer and the video without the appearance of the lecturer. After testing the level of their learning flow and teaching presence, the differences between groups were analyzed. According to the results of the analysis, the learning flow and teaching presence of groups who learned the videos in which the lecturer appeared were significantly higher than the groups who learned the videos without the appearance of the lecturer. Second, the effects of whether the lecturer appears or not according to DISC on learning flow were significant. However, the effects of DISC, and the interactive effect of DISC and the lecturer appearance were found to have no significant interactive effect on learning flow. Third, the effects of whether the lecturer appears or not according to DISC on teaching presence were significant, and the effects of DISC on teaching presence were not significant, but the interactive effect of lecturer appearance and DISC was significant. These findings suggest that lecture videos with the appearance of the lecturer generally have better effect. In particular, in order to enhance teaching presence, it is effective to decide whether the lecturer appears or not by considering its interactive effects with learners' DISC.

Objectives: This pre-post quasi-experimental study was designed to investigate the effects of school based smoking prevention education on knowledge and attitude toward smoking, and the satisfaction of education among middle school students. Methods: The subjects included 94 middle school students in the experimental group. and 87 students in the control group. The educational content contained smoking refusal skills, which were taught through lectures and videos. Data collection was achieved using a self-reported questionnaire developed by the investigator. Data were analyzed with the SPSS 10.0 program including frequency, percentile, X2, paired t-test, and ANCOVA. Results: The results were as follows: 1. After the smoking prevention education, the smoking knowledge of the experimental group was significantly improved, whereas that of control group didn't change significantly. 2. There were no significant differences between pretest and post test attitude scores in both groups. 3. Refusal skill was the education content that provided the highest satisfaction for the subjects, and the degree of satisfaction was higher with video watching than with a lecture. Conclusion: Smoking prevention education for middle school students increased their level of smoking knowledge, but did not affect their attitudes toward smoking. Therefore, it is necessary to develop a more effective program, and to evaluate the effects of a long term education program with further studies.

With proliferation of the internet, the internet ethics in contrast to existing ethics has been recognized as one of the disciplines. Internet ethics is one of liberal arts courses in a college as well as a class in elementary, middle and high schools. We also have taught this subject for a number of years. In order to effectively communicate to students the internet ethics course as computer scientists, we gave some demonstration practice lectures by taking advantage of internet ethics related videos. Since the latest UCC presentation and its discussion were performed, it was helpful for students to recognize the internet ethical issues and concerns. We confirmed that classroom students' concentration and understanding for internet ethics increases by a survey of the regular attendees. This research presented a lecture practice case model to teach comprehensive internet ethics topics to college students effectively.

A number of middle and high school students are selected at the Korea Astronomy Olympiad (KAO) in every year. In the first stage of the selection, the resume, school transcript, and recommendation letters from teachers are referred. In the second stage, after video lectures and weekend observation classes, students are tested with on-line homeworks, and interviewed through internet. For 118 students who have gone through the second stage of the 2012 KAO, we have conducted a questionnaire survey, which asks the students the motivation and preparation for the KAO. The survey has also included inquiries for the selection process and education program of the 2012 KAO; the replies will be used as feedbacks for the next year's KAO. The survey has revealed that the first stage worked well, while the second stage needs to be improved in terms of fairness and objectivity. We have found that most students received private tutorings for the KAO, so we suggest efforts should be made for students to be able to prepare the KAO without receiving private tutorings.

Purpose: The purpose of this study was to compare the effectiveness of training using an intravenous (IV) arm model versus a computer simulator for IV injections. Method: Study was a quasi-experimental study conducted with 106 nursing students. Participants were divided into two groups: the IV Arm Group using a mannequin arm model (control group) and the Computer Simulator Group using the Virtual IV demonstration (experimental group). Theoretical lectures and video presentations on IV injections were given to both groups. Each group went through the training practice using the IV arm or computer simulator. After the completion of training, questionnaires were given to the students to evaluate their learning attitudes and experiences, self-confidence in IV injection, and satisfaction with the training materials. Results: Student satisfaction with the training materials including the reality, usefulness, and educational effects showed notable differences between the two groups with the Computer Simulator group reporting more positive effects that the IV Arm group. However, there was no statistical difference between the two groups in the categories of learning attitude, learning experience, or self-confidence. Conclusion: While there was a differences in strengths and weaknesses of the two methods, both methods should be considered for practice and further study needs to be done on educational effectiveness.

The aim of this study is to establish an object of environmental education in liberal arts, and to develop a teaming program and search for the most effective environmental teaching method. At first this study analyzed the current situations and problems of the present environmental education in the liberal arts. As a result of this analysis, I found that, most of environmental educations have been conducted mainly by an approach of natural science, inevitably they should have limits in which students can't have holistic view in solve the environmental problem. Due to the fact that, many students were attending lectures, teaching methods were limited in the forms lecture and video tapes. As I applied educational programs with various teaching methods for students in order to change cognition and value toward environment, I found that there was no significant difference of cognition even after applying the programs. This may be interpreted as, most students already had very sound and sustainable environmental view. But some programs with teaching method using role play, debate, cyber-debate lead students to have interest in environments, thus actively participating in the class. These methods, taking into consideration, the hundreds of enrolled students, seem to pose a problem in actual application. The most important matter is, how to develop a cognition and value toward environment into environmental behavior. Therefore, in the future, aim is to study what determines the factors for causing environmental behavior from a cognition and value of the environment, and a development of programs in this regard will be necessary.

Purpose: The purpose of this study was to examine the effects of a death preparation education program for nurses working in convalescent hospitals on death anxiety, death attitudes, and attitudes toward end-of-life care. Methods: This was a quasi-experimental study with a non-equivalent control group, pre-test and post-test design. Among 53 participants, 26 were assigned to the non-equivalent experimental group and 27 to the control group. The program was performed in the formats of lectures, video-watching, group discussions, and sharing, and consisted of 10 sessions held twice a week, for 5 weeks (90 minutes per session). Data were analyzed using descriptive statistics, the t-test, and the chisquare test in SPSS version 21.0. Results: Significant differences between the experimental and control groups were observed in death anxiety (t=7.62, P<0.001), death attitudes (t=-7.58, P<0.001), and attitudes to end-of-life care (t=-10.30, P<0.001). Conclusion: It was confirmed that the death preparation education program reduced death anxiety and had a positive effect on death attitudes and attitudes toward end-of-life care. Based on the results of this study, it is expected that specialized and systematic education that can increase the implementation and stability of death preparation education in various fields, including nursing, will have a positive effect on both hospice patients and members of society more broadly.

The Necessity of Cyber University. Within the rapidly changing environment of global economics, the environment of higher education in the universities, also, has been, encountering various changes. Popularization on higher education related to 1lifetime education system, putting emphasis on the productivity of education services and the acquisition of competitiveness through the market of open education, the breakdown of the ivory tower and the Multiversitization of universities, importance of obtaining information in the universities, and cooperation between domestic and oversea universities, industry and educational system must be acquired. Therefore, in order to adequately cope wi th these kinds of rapid changes in the education environment, operating Cyber University by utilizing various information technologies and its fixations such as Internet, E-mail, CD-ROMs, Interact ive Video Networks (Video Conferencing, Video on Demand), TV, Cable etc., which has no time or location limitation, is needed. Using informal ion and telecommunication technologies, especially the Internet is expected to Or ing about many changes in the social, economics and educational area. Among the many changes scholars have predicted, the development and fixations of Distant Learning or Cyber University was the most dominant factor. In the case of U. S. A., Cyber University has already been established and in under operation by the Federate Governments of 13 states. Any other universities (around 500 universities has been opened until1 now), with the help of the government and private citizens have been able to partly operate the Cyber University and is planning on enlarging step-by-step in the future. It could be seen not only as U. S. A. trying to elevate its higher education through their leading information technologies, but also could be seen as their objective in putting efforts on subordinating the culture of the education worldwide. UTRA University in U. S. A., for example, is already exporting its class lectures to China, and Indonesia regions. Influenced by the Cyber University current in the U.S., the Universities in Korea is willing .to arrange various forms of Cyber Universities. In line with this, at JUNAM National University, internet based Cyber University, which has set about its work on July of 1997, is in the state of operating about 100 Cyber Universities. Also, in the case of Hanam University, the Distant Learning classes are at its final stage of being established; this is a link in the rapid speed project of setting an example by the Korean Government. In addition, the department of education has selected 5 universities, including Seoul Cyber Design University for experimentation and is in the stage of strategic operation. Over 100 universities in Korea are speeding up its preparation for operating Cyber University. This form of Distant Learning goes beyond the walls of universities and is in the trend of being diffused in business areas or in various training programs of financial organizations and more. Here, in the hope that this material would some what be of help to other Universities which are preparing for Cyber University, I would 1ike to introduce some general concepts of the components forming Cyber University and Open Education System which has been established by JUNAM University. System of Cyber University could be seen as a general solution offered by tile computer technologies for the management on the students, Lectures On Demand, real hour based and satellite classes, media product ion lab for the production of the multimedia Contents, electronic library, the Groupware enabling exchange of information between students and professors. Arranging general concepts of components in the aspect of Cyber University and Open Education, it would be expressed in the form of the establishment of Cyber University and the service of Open Education as can be seen in the diagram below.
