PURPOSE. The aim of this study was to introduce rating criteria to evaluate student performance in a newly developed, digital wax-up preclinical program for computer-aided design (CAD) of full-coverage crowns and preliminarily investigate the reliability and internal consistency of the rating system. MATERIALS AND METHODS. This study, conducted in 2017, enrolled 47 fifth-year dental students of Okayama University Dental School. Digital wax-up training included a fundamental practice using computer graphics (CG), multipurpose CAD software programs, and an advanced practice to execute a digital wax-up of the right mandibular second molar (#47). Each student's digital wax-up work (stereolithography data) was evaluated by two instructors using seven qualitative criteria. The total qualitative score (0-90) of the criteria was calculated. The total volumetric discrepancy between each student's digital wax-up work and a reference prepared by an instructor was automatically measured by the CAD software. The inter-rater reliability of each criterion was analyzed using a weighted kappa index. The relationship between the total volume discrepancy and the total qualitative score was analyzed using Spearman's correlation. RESULTS. The weighted kappa values for the seven qualitative criteria ranged from 0.62 - 0.93. The total qualitative score and the total volumetric discrepancy were negatively correlated (ρ = -0.27, P = .09, respectively); however, this was not statistically significant. CONCLUSION. The established qualitative criteria to evaluate students' work showed sufficiently high inter-rater reliability; however, the digitally measured volumetric discrepancy could not sufficiently predict the total qualitative score.

The purpose of this study was to develop a dietary life education program for adolescents and evaluate its effectiveness. The program was divided into three areas: 'Natam' (taste education), 'Wetam' (traditional dietary life education), and 'Gitam' (sustainable dietary life education), consisting of a total of 10 units primarily focused on cooking activities. For participants aged 14~17 years, face-to-face pilot education was conducted by a trained instructor once a week for 10 weeks. A questionnaire survey was performed to evaluate the educational effect(n=72) and satisfaction(n=82) during education period. Significant improvements were observed in knowledge levels for the 'traditional dietary life education', and 'sustainable dietary life education' which were identified as insufficient in the preliminary survey. Attitude and behavior levels were significantly improved across all areas. Satisfaction was high with a score of 4 out of 5 points for all areas. In conclusion, this program was found to be effective, and further emphasis should be placed on traditional and sustainable dietary life education to enhance its impact.

The purpose of this study was to examine the phenomena that occurred when the students were practicing flip-learning lessons and to present the good points and the unsatisfactory points to improve the students' learning pleasure. Therefore, it is aimed to provide the basic data and the advantages and disadvantages which are needed to apply the flip learning method which is newly emerging recently to the university instruction. The method of this study was a questionnaire survey to understand the perception of flip learning. Based on the results of this study, the following conclusions are presented. First, the experience of flip learning instruction was first encountered by 50% of college students. Second, the students showed a very low tendency in practicing the flip learning instruction(video watching) the instructor intended. Third, college students have a habit of learning that they are not ready for pre-study of the subject. Fourth, the perception of flip learning lesson through the provision of video was highly positive. Fifthly, flip learning lessons have the advantage of being able to learn regardless of the time and place that they have, but they are not actively involved if they are not actually reflected in the test or grades. In conclusion, it was found that college students became accustomed to the incentive-style lessons due to the application of various learning techniques from elementary school age, making it difficult to participate in voluntary learning.

This study is to examine the current situation of Korean sports culture and seek its pointing spot and alternatives to its advancement. First, out of the current situation of Korean sports culture, that of school physical education, even though it is the most significant basis for sports culture, is riddled with so many contradictions that the pace of its change is very slow. Only when the elite sport is normally operated and well coordinated, can it have the value of existence as a stable field. The mass sports have been determined to have insufficient self-reliance of sport facilities, sport programs and instructor management since the national policy for physical education has been focused on the elite sports. Second, internalization of "Winning First Policy" as a pointing spot of sports culture has been found to be an production of the value system with not only a very passive tendency caused by political changes. Accordingly, the concept of sports-culturism has been introduced as a new pointing spot of sports culture and then it has been emphasized that the sports-culturism is the awareness of sports advancement. Third, in terms of finding any alternatives to sports culture, enacting a school physical education promotion law has a very significant meaning as its advancement method. Next, the immorality of and match-fixing by sport organizations and the umpire's bad call have been mentioned as major problems to the elite sport, and also the alternative to each field has been set. Last, it has been assented with emphasis that Law of Sports for All should be enacted for the public sports to have any significance of the times.

The purpose of this study is to confirm the effect of recording online classes and real-time video classes on other behaviors, lecture satisfaction, and lecture flow in during the COVID-19 period. Data were collected and analysis using a structured questionnaire from May 20th to June 4th in 2021 for 550 nursing students in the D University. As a result of the study, it was found that there were more others behaviors in record online classes than in real-time online classes (t=-2.00, p=.046), lecture satisfaction(t=-1.54, p=.124) and lecture flow in real-time online classes it was higher in the record online classes (t=-.63, p=.529), but it was not statistically significant. However, the 2nd year students who participated in the two types of online classes showed statistically significantly higher lecture satisfaction (t=13.55, p=.000) and lecture flow(t=4.48, p=.004). And 4 th grade students of others behaviors was statistically significantly lower (t=4.68, p=.003). In the multiple regression analysis, the main factor affecting lecture flow was lecture satisfaction, and the explanatory power of the model was 55.1% in record online classes (F=128.49, p <.01), and in real-time classes 47.2%(F=77.24, p<.01). In the future, research should be conducted to confirm the difference between the two types of online classes of the same instructor and the difference in other things, lecture satisfaction, and class commitment that appear after applying learner-centered learning.

During the COVID-19 pandemic, the use of video classes and real-time online education has increased, but the lack of interaction between instructors and learners remains a challenging problem to be resolved. This paper designs and implements a learning support system that utilizes a digital human to improve faculty-student interaction, which plays an important role in increasing the educational effect and satisfaction of real-time online classes. In this paper, a digital human participates in a class as a virtual learner and asks questions raised by other learners through an anonymous chat system to the instructor on behalf of the learners. In addition, as a class facilitator, the digital human analyzes the lecturer's speech in real time and provides it to the learner in the form of a summary of the class, thereby facilitating faculty-student interaction. In order to confirm that the proposed system can be used in actual online real-time classes, we apply our system to Zoom classes. Experimental results show that facilitated Q&A and real-time class summaries are successfully provided through our digital human-based learning support system.

To be an adjunct professor(gyeomgyosu) literally means to act as an instructor while also holding a different position. Adjunct professors were initially introduced under Confucianism. Gradually, technical offices also appointed adjunct professors using Confucian-educated bureaucrats for the purpose of educating lower-level technical officials and cadets. This paper examines the history of the civil service system related to adjunct professors through the Code of Laws, and examines those who have been appointed to the public office described in various documents. This paper argues that changes in the medical office's adjunct professor system reflect changes in the national medical talent training policy. The main basis of specific recognizing medical personnel is to decouple the appointment of Confucian scholars from that of full-time doctors. The replacement of the role of medical educators from Confucian scholars to full-time doctors was largely accomplished during the reign of King Jungjong(中宗) and was completed during the period of King Injo(仁祖). The time when Euiyakdongcham was created and the Office of Euiyakdongcham was established coincided with the period when the adjunct professor was disrupted in the medical office. However, this change in the adjunct professor system of medical authorities is in contrast to interpretation, which is a representative technical field. In the case of interpretation, Moonshin's sayeogwon position as adjunct professor was maintained even in the late Joseon Dynasty, and apart from this, there was a hanhagmunsin in Seungmunwon. Interpreter families had institutional arrangements that prevented them from making interpretation their own monopoly. Therefore, families of medical bureaucrats had more room for institutional growth than those of bureaucratic interpreters. Of course, these institutional devices did not prevent the growth of interpreting bureaucratic families in the late Joseon Dynasty. However, the situation in which medicine was accepted only as a kind of knowledge, not as an object of full-time work for sadaebue, would have been an opportunity to rise for those in technical jobs who were full-time medicine. As medicine became more differentiated and developed in the late Joseon Dynasty, medical knowledge and the knowledge about the medical profession became more important. The politicians could not avoid the use of a philosophically oriented system in which a confucian-educated bureaucrat equipped with only Confucian knowledge might replace a full-time doctor. Thus, the contradiction between the reality and the ideal of ignoring or denying reality was reproduced like other Confucian-centered societies. These contradictions have implications for us living in the modern age. Establishing the relationship between philosophy (or belief) and technology should not end with the superiority of one side or the other.

The term edutech has recently been attracting attention as the convergence of education and technology is emphasized. Schools are also exploring teaching methods using edutech. The purpose of this study is to analyze the satisfaction of 210 radiology students after using Quizn Platform and the difference in satisfaction with Quizn Platform according to general characteristics. The research results are as follows. First, as a result of the satisfaction analysis according to class type, the following order was practical class, theory + practice class, and theory class. Second, the desired teaching methods among theory classes according to general characteristics were core classes (quiz solving), lecture-style classes, discussions, and discussion classes. Third, 'Quizn was used appropriately in class.' had the highest score at 4.27±0.60, and 'I am very interested in this subject.' had the lowest score at 3.98±0.74. Additionally, there was no significant difference in response to the teaching method (p>0.05). Fourth, 'Applying Quizn to class was interesting and fun' showed the highest score at 4.24±0.94, and 'Institutional support must be provided to continue using Quizn at 3.49±0.96. Additionally, there was no significant difference in satisfaction with classes according to gender and age (p>0.05). As a limitation of this study, although we investigated the satisfaction of students using Quizn, we were unable to investigate the satisfaction of instructors who interact with students. In the future, research that considers instructor satisfaction in classes using edutech should be conducted. Universities must provide institutional support and continuous interest until edutech is selected and utilized.
