Non-face-to-face lectures have become a necessity rather than an option since COVID-19, and in order to improve the quality of university education, it is necessary to explore the properties of non-face-to-face lectures and make active efforts to improve them. This study, focusing on this, aims to provide basic data necessary for decision-making for non-face-to-face lecture design by analyzing the relative importance and execution satisfaction of non-face-to-face lecture attributes for professors and students. Based on previous research, a questionnaire was constructed by deriving 4 factors from 1st layer and 17 from 2nd layer attributes of non-face-to-face lectures. A total of 180 valid samples were used for analysis, including 60 professors and 120 students. The importance of the non-face-to-face lecture properties was calculated by obtaining the weights for each stratified element through AHP(Analytic Hierachy Process) analysis, and performance satisfaction was calculated through statistical analysis based on the Likert 5-point scale. As a result of the AHP analysis, both the professor group and the student group had the same priority for the first tier factors, but there was a difference in the priorities between the second tier factors, so it seems necessary to discuss this. As a result of the IPA(Importance Performance Analysis) analysis, the professor group selected the level of interaction as an area to focus on, and it was confirmed that research and investment in teaching methods for smooth interaction are necessary. The student group was able to confirm that it is urgent to improve and invest in the current situation so that the system can be operated stably by selecting the system stability. This study uses AHP analysis for professors and students groups to derive relative importance and priority, and calculates the IPA matrix using IPA analysis to establish the basis for decision-making on future face-to-face and non-face-to-face lecture design and revision. It is meaningful that it was presented.

This study examined whether learner-customized start-up education, such as business consulting, functions effectively as part of universities' start-up support and whether business consulting positively strengthened start-up capabilities compared to consulting from other institutions. Furthermore, it explored the direction of universities' start-up support development by harnessing customized education, such as business consulting. The results of the study are as follows. First, business consulting had a positive impact. It informed the shortcomings of individual founders (teams) and identified the direction for improvement. Second, compared to consulting from other institutions, the fact that it formed a relationship between the consultant and the student beyond the business relationship and that it was conducted for free on campus have a relative advantage. Such business consulting enabled university students to see the world more maturely. Third, this study argues that customized start-up businesses can generate synergy with school curriculum and other non-curricular subjects. Based on this perception, it designed a method to build a co-curriculum education system. This study is significant because it investigated satisfaction and the possibility of a customized start-up business with business consulting as a representative case, exploring the direction of support for start-up education students want.

The revitalization of science museum depends on the number of qualified docents who can meet the museum visitors' educational needs. However, the current unstructured docent system is not sufficient to meet the goal. Forty six docents currently working in science museums were surveyed about docent training program, current working conditions, and docent professional program in order to propose a viable system providing a docent profession. Data were collected through surveys with 46 docents, interviews with two experienced docents, and several artifacts from the science museum and selected docents. The surveys consisted of 47 items asking about personal biography, docent's perception, docents training program they took, current working conditions, and supplementary professional program. The conclusion of this study is as follows; First, there must be recognition about docents who can play educator's roles which are different from those of general volunteers in terms of recruiting and training system in science museum. Second, docents need to take training and supplementary professional courses that focus on observing and educating visitors in the field. Third, we need a docent management system by employing a well structured evaluating tools. A well established docent system will bring forth the enhancement of science museum education and the increase of science popularization by providing visitors with the quality educational services.

The purpose of this study was to evaluate the effects and define the educational strategies of the cyber education offered to students for Bachelor of Science degree program(RN-BSN). The participants in this study were 67 students in two courses, Growth and Development, and Nursing Process. The main components of the cyber classes were the electronic board and on-line discussion board. The study was conducted from March 4, 2001 to July 23, 2001 at Y University in Seoul, Korea. To examine the effects of the cyber education, learning motivation, and learning satisfaction were measured by questionnaires to the students before the initial class and after completing the class. Learning achievement was measured by the grades for each course. The data were analyzed using frequencies, t-test, and paired t-test. The specific results of the course evaluation were compared and analysis was done to examine differences between traditional classroom teaching and cyber teaching. The study results are as follows: 1. There were no significant differences on total scores for learning motivation between pre-cyber education and post-cyber education. However, there were significant decreases in the post test compared to the pre test for the items, ' I'd like to get as high a score as possible compared to other students (t=-2.20, p=.03)' and ' I'm sure to acquire good grades(t=-5.22, p=.00) '. 2. The average score for learning satisfaction using cyber education was high at 3.52. 3. To define learning achievement using cyber education, grades for students taking cyber classes this year were compared to student grades for a class using traditional lassroom teaching last year. The score was significantly higher for classroom students in the 'Growth and Development' course (t=-3.5, p<.001), and the score was significantly higher for the cyber education students in the 'Nursing Process' course (t=4.3, p<.000). 4. The average of post scores on computer competency was significantly higher on six items, general knowledge about computers, data management and data research, ability to communicate using computer, and internet surfing. On the basis of the above findings, this study suggests that cyber education in nursing courses is effective and readily available. However, it is recommended that consideration be given to characteristics of the course when developing cyber education programs for nursing courses.

The purpose of this study is to investigate the perception on video material making and the effect on science teaching ability after conducting non-face-to-face teaching material making activity for elementary pre-service teachers. This activity consisted two processes. One is that elementary pre-service teachers conduct inquiry, understand related science concepts, analyze science textbooks and then make video material. The other is that they watch video materials produced by colleagues. This study was conducted on 89 elementary pre-service teachers for 8 weeks. After this activity was completed, the perception on video material making and the effect on science teaching ability of elementary pre-service teachers were investigated, and the results were analyzed. In the process of making and watching non-face-to-face teaching materials, elementary pre-service teachers showed positive results in teaching-learning, video production, and emotion and attitude toward video material making. In addition, it was found that they improved their science teaching ability through this activity and were very satisfied with this activity. However, they also mentioned several disappointments such as exclusion of learners' right to self-determination, lack of various communication channels, and errors in content of materials. This suggests that if these problems are solved, non-face-to-face classes can also be a good form of class.

At a time when interest in the educational use of ChatGPT is increasing, it is necessary to investigate the perception of ChatGPT among college students. A survey was conducted to compare the current status of internet and interactive artificial intelligence use and perceptions of ChatGPT after using it in the following courses in Spring 2023; 'Family Life and Culture', 'Fashion and Museums', and 'Fashion in Movies' in the first semester of 2023. We also looked at comparative analysis reports and reflection diaries. Information for coursework was mainly obtained through internet searches and articles, but only 9.84% used interactive AI, showing that its application to learning is still insufficient. ChatGPT was first used in the Spring semester of 2023, and ChatGPT was mainly used among conversational AI. ChatGPT is a bit lacking in terms of information accuracy and reliability, but it is convenient because it allows students to find information while interacting easily and quickly, and the satisfaction level was high, so there was a willingness to use ChatGPT more actively in the future. Regarding the impact of ChatGPT on education, students said that it was positive that they were self-directed and that they set up a cooperative class process to verify information through group discussions and problem-solving attitudes through questions. However, problems were recognized that lowered trust, such as plagiarism, copyright, data bias, lack of up-to-date data learning, and generation of inaccurate or incorrect information, which need to be improved.

The development of smart devices has brought about significant changes in daily life and one of the most significant changes is the virtual reality zone. Virtual reality is a technology that creates the illusion that a 3D high-resolution image has already been created using a display device just like it does in itself. Unrealized subjects are forced to rely on audiovisual materials, resulting in a decline in the concentration of practices and the quality of classes. It used virtual reality to develop effective teaching materials for radiology students. In order to produce a video clip bridge using virtual reality, a radiology clinic was selected to conduct two exposures from July to September 2017. The video was produced taking into account the radiology and work flow chart and filming was carried out in two separate locations : in the computerized tomography unit and in the LINAC room. Prior to filming the scenario and the filming route were checked in advance to facilitate editing of the video. Modeling and mapping was performed in a PC environment using the Window XP operating system. Using two leading virtual reality camera Gopro Hero, CC pixels were produced using a 4K UHD, Adobe, followed by an 8 megapixel resolution of $3,840{\times}2,160/4,096{\times}2,160$. Total regeneration time was performed in about 5 minutes during the production of using virtual reality to prevent vomiting and dizziness. Currently developed virtual reality radiation and educational contents are being used to secure the market and extend the promotion process to be used by various institutions. The researchers will investigate the satisfaction level of radiation and educational contents using virtual reality and carry out supplementary tasks depending on the results.
