After pre-service teachers become teachers, traditional patterns of classroom discourse which they had experienced as students affect their classroom discourse implicitly. For this reason, it is needed to get a new insight for evaluating and reflecting a teacher's classroom discourse. In this study, I analyzed the information flow of science classes of pre-service elementary school teachers. The finding showed that teachers' organizational skills for students' information made advanced science classes by maintaining discourse cohesions. And the findings also showed a way how to analyze, evaluate or reflect science classroom discourse. This trial could contribute to find out the characteristics of teachers' science classroom discourse and show the directions to them how to change their classes beyond impressionable evaluations for their science classes.

After COVID-19, various metaverse platforms for online lectures are being provided. Most of the classrooms are tiered type, and they are divided into intensive classrooms and open classrooms depending on the shape of the classrooms. Intensive classrooms provide a one-sided lecture format, so there are many difficulties in conducting communication-based classes that carry out team missions like PBL classes. In this study, we propose a metaverse classroom that applies the functions of a multiplayer online role-playing game (MMORPG), one of the game genres suitable for PBL classes. The proposed system provides various interaction techniques for PBL classes. We evaluated user satisfaction when this was applied to actual classes. As a result of the evaluation, it was found that users preferred text and voice chatting more than video chatting and solving missions like games was very helpful in online classes.

The purpose of this study was to examine the effect of scientific discussion classes focusing problem finding on the primary school students' scientific creative problem solving ability, science process skills and attitude toward science class. To verify this research problem, the subject of this study was fifth-grade students selected from four classes of M elementary school located in Busan city. For four months, the experimental group of 51 students was taught using the "scientific discussion classes focusing problem finding". The control group also of 53 students was taught in normal classes which used a text-book. All students were given pre and post test to verify the effects of scientific discussion classes focusing problem finding on the primary school students' scientific creative problem solving ability, science process skills and attitude toward science class. The results from this study are as the following. First, the scientific discussion classes focusing problem finding were effective in scientific creative problem solving ability among the primary school students. It is possibly because in the process where one student compare his/her own thoughts with the others' ones and discuss them. Second, the scientific discussion classes focusing problem finding were effective in science process skills among the primary school students. Third, the scientific discussion classes focusing problem finding were effective in attitude toward science class. In conclusion, the scientific discussion classes focusing problem finding had positive effects on improvement of primary school students' scientific creative problem solving ability, science process skills and also could lead to a change in students' cognition about science class to a positive way. Therefore, the scientific discussion class focusing problem finding is hopefully to be provided as an effective instructive strategy of science class in school in the future.

Nowadays, as the era of aging is developing remarkably fast, conventional disease treatments such as surgery or emergency therapy are now being substituted to 'health promotion' and 'health prevention through whole-life management. Recently, many oriental medicine colleges are teaching subjects related to Yangsaeng and Gigong. However, detail investigation about the exact education situation and correlation between among subjects has not been performed yet. Thus, in this research, I collected data about each oriental medicine college's Yangsaeng/Gigong-related subjects' prevalence and management situation through the analysis of 'National Education Report about Korea's Oriental Medicine Colleges' and direct investigation, First, I analyzed oriental medicine colleges' education object. Among 11 basic medicine subjects, there were 2 subjects related to Yangsaeng and Gigong. And among 13 clinical medicine subjects, there were 7 subjects related to Yangsaeng and Gigong. In these subjects, the word 'Yangsaeng' was used for 14 times. The word 'Gigong' was used for 5 times and the words 'natural medicine' and 'alternative medicine' were used for 4 times. Total class hours related to Yangsaeng and Gigong were 19.6 hours (practice classes were 4.6 hours). Each class of subjects had 'study objects'. Study objects were categorized into A (Essential) and B (Recommendation) Items. There were44 A items and 23 B items. Among 11 oriental medicine colleges all over Korea, 10 classes related to Yangsaeng and Gigong existed in 9colleges. 7 classes were included in pre-OM course and 3 classes were included in major-OM course. 6 classes were taught only for one semester and 4 classes were taught for 2 semesters. 6 classes were single unit and 4 classes were 2-units sunjects. 3 classes were held 3 hours a week. 6 classes were held 2 hours a week and one class was held an hour per week. In conclusion, each oriental medicine college should focus on the education and research about Yangsaeng and Gigong. To achieve this object, systemic regulation and specialized human resources should also be made.

The purpose of this study is to verify the effectiveness of non-face-to-face lectures conducted at universities in Korea under the influence of COVID-19. So this study analyzed the satisfaction level of the students according to the type of class operation, such as face-to-face classes and remote video classes. To this end, this study compared the differences in class satisfaction by class type and class size for a total of 8,707 courses operated by a university between 2019 and 2020. The study found that the satisfaction level of the remote video class was significantly high. In addition, the combination of remote video classes and face-to-face was more satisfactory than other cases. On the other hand, the satisfaction level of small classes in both face-to-face and remote video classes was higher than that of medium or large classes. This means that even remote video classes are highly satisfactory in small-scale classes. Based on the findings, the study proposes a paradigm for new college classes.

The purpose of this study was to examine the state of management and science teachers perception of science classes and clubs in secondary schools. There ware 125 participants (75 middle school teachers and 50 high school teachers) from eight metropolitan cities and local areas, and more than 80% of the participants had managed science classes or clubs. Results found that a significant number of science teachers felt it necessary to manage science classes and/or clubs in secondary schools. They believed the classes and/or clubs to be beneficial in the activation of students' interest in science, even though they might not be effective ways of improving scientific achievement. In addition, it was found that secondary science teachers desire financial support, in-service programs, and efficacious programs supporting science class and club management.

In deep learning classification tasks, most models frequently assume that all labels are available for the training datasets. As such strategies to learn new concepts from unlabeled datasets are scarce. In fingerprint classification tasks, most of the fingerprint datasets are labelled using the subject/individual and fingerprint datasets labelled with finger type classes are scarce. In this paper, authors have developed approaches of classifying fingerprint images using the majorly known fingerprint classes. Our study provides a flexible method to learn new classes of fingerprints. Our classifier model combines both the clustering technique and use of deep learning to cluster and hence label the fingerprint images into appropriate classes. The K means clustering strategy explores the label uncertainty and high-density regions from unlabeled data to be clustered. Using similarity index, five clusters are created. Deep learning is then used to train a model using a publicly known fingerprint dataset with known finger class types. A prediction technique is then employed to predict the classes of the clusters from the trained model. Our proposed model is better and has less computational costs in learning new classes and hence significantly saving on labelling costs of fingerprint images.

Background: This study aims to investigate the perception and actual situation of online classes of college physical therapy students after COVID-19. In addition, it is necessary to conduct a fact-finding survey on how physical therapy students who have experienced online classes think about the online class method, what are the overall problems, and to what extent they are satisfied. Methods: The subjects of this study were 102 students in the 3rd year of physical therapy at University A, and the survey period was from June 10 to June 23, 2020, and the perception and use of online classes and self-regulated learning ability were investigated. Design: Cross-section study. Results: The perception of online lectures, it was found that the perception of online classes after actual online classes was better than the perceptions before watching (utilization), and satisfaction with online classes was generally high. There was a significant difference according to the grades in self regulated learning. The data values measured in this study were analyzed using SPSS (Statistical Package for Social Science) Windows version 12.0 statistical program. Conclusion: These results suggest that in future research, it is necessary to study the perceptions and actual conditions of each class compared to online classes and face-to-face classes.
