In the educational environment of the post-COVID-19 era, metaverse learning, which can improve the disadvantages of online learning and improve learning outcomes, is attracting attention. Metaverse is expected to play an important role as a learning experience platform (LXP) that can provide immersion and experience for learners. In order to successfully introduce and utilize metaverse learning that utilizes the metaverse platform, teachers' knowledge of metaverse-related technologies and pedagogical convergence is important. So far, teacher knowledge for educational use of the metaverse has not been explored. In this regard, this study explored the TPACK (Technological, Pedagogical And Content Knowledge) framework as a teacher's knowledge system for metaverse learning. Based on this, this study designed the class contents of metaverse learning. The results of this study are expected to diffuse the importance of TPACK required for metaverse learning and contribute to the development of teachers' competence.

The purpose of this study was to examine the effect of diabetes education on diabetic management by determining the changes of the knowledge and practice for diet therapy and blood glucose level pre-training and post-training. Statistical data analyses were completed using the SPSS 11.0 program. The results can be summarized as follows : The average age of the subjects was 52.8 years old, the period of suffering from diabetes was 7.9 years and 31% of the patients had a history of diabetes in their family members. In life style for self-management, they showed lower levels in drinking post-training, and significantly higher exercise levels post-training (P<0.05). Regarding the level of knowledge for diet, they showed significantly higher levels post-training in eight items such as importance of diet therapy for diabetes (p<0.005), principle of diet therapy (p<0.005), nutrient composition of foods (p<0.005), carbohydrate composition of foods (p<0.005), calorie prescribed to themselves (p<0.001), exchange units prescribed to themselves (p<0.005), exchange food items and exchanges units of cereal & grains (p<0.005) and exchange food items and exchanges units of fruit & juices (p<0.005). Regarding the practices of diet, they showed significantly higher levels of practice in keeping permitted meal size (p<0.005), using food exchange list (p<0.005), keeping exact meal times (p<0.001) and restricting most foods to eat (P<0.01) post-training. When measuring their bodies, average weight was lower post-training. Obesity was significantly lower post-training (p<0.01), and blood pressure both in systolic and diastolic was lower. Postcardinal-2hour blood glucose level decreased significantly from 268.4$\pm$98.9 pre-training to 180.9$\pm$48.4 post-training (p<0.001).

The purpose of this study was to develop a sexuality education program for early adolescents. The overall goals of the program were to not only increase knowledge and skirts, but also to improve the awareness of healthy sex in order to promote premarital abstinence, parent-teen communication and parental awareness of the importance of parental roles and responsibilities in prevention of sexual problems of the early adolescent. The program consisted of six sessions: puberty changes during adolescence, the meaning of sexuality, sexual drives in dating relationships, understanding of the risks associated with early sexual involvement and support for postponing sexual activities, managing and avoiding sexually risky situations, the importance of communications with parents about issues related to sexuality. The program evaluation had three steps: pre-test, immediate post-test and two month follow-up post test. The results showed that the program had a significantly positive effect on the improvement of adolescent's knowledge about sex, and attitudes and behaviors toward sex, particularly in the immediate post-test. At the two month follow-up assessment, the effect of the program still remained strong, though there was a sight and partial reduction which was not statistically significant. Most of the program participants expressed a high level of satisfaction with the program. Parental involvement appeared to be effective as well. Recommendations for further study include: to re-evaluate the curriculum for various other participants. In addition, further study which would compare post-test results of these participants with a comparison group of peers who did not receive the program would be valuable. The author believes that the program can be used in implementing specific subjects (sessions) in new settings, as well as implementing the entire package of the program.

The smoking preventive education has been carried out 4 times and the time for each experiment was 40 minutes. The collected data has been analysed by the purpose into $\chi^2-test$, t-test,. F-test, Duncan multiple range test with SPSS. The results of study would be as follows 1. The rate of smoking experience is $17.3\%$ and the biggest motive $(75\%)$ is curiosity. Also $5.4\%$ of respondents reply to have friends smoking a little. 2. The first hypothesis - the group with smoking preventive education would have much knowledge about smoking than comparison group - would be supported with statistical data (t=-3.329, p=.000). 3. The second hypothesis - the group with smoking preventive education would show higher attitude than the other group - would also be backed by statistically meaningful difference (t=-3.856, p=.000). 4. The variables of extent for smoking knowledge would be school record and the variables of extent for smoking attitude is friends' smoking, parents' reaction, experience until now and plan from now on.

This study attempts to supplement what is known about the influence of prior knowledge on second language listening comprehension. To do so, the study examines the effect of prior knowledge and language proficiency on the ability of L2 listeners to understand texts. The purpose of an experiment was to determine the effect of topic familiarity on the L2 listening comprehension ability of subjects who varied in L2 listening proficiency level. The subjects (N=117) were selected from a population of college students enrolled in the Departments of English and Business in Korea. English listening proficiency levels were designated on the basis of TOEFL listening scores. Subjects listened twice each to texts (more familiar and less familiar). After listening to each text, a ten-item objective test was administered to test the subjects' comprehension of the information presented in the text. Objective tests were analyzed. using repeated measures analysis. A post hoc test was conducted to identify the means that were significantly different. This study yielded the following results: (1) subjects with high prior knowledge comprehended texts significantly better than did subjects with low prior knowledge; (2) the level of L2 listening proficiency had a significant effect on the L2 listening comprehension of texts, but there was no interaction between prior knowledge and the level of L2 listening proficiency.

This study was conducted to investigate the effectiveness of a nutrition and exercise education program on weight control and nutrition knowledge. The nutrition-exercise educational period was 12 weeks. The subjects were 160 adult women with an average age of 48.1 years. We investigated general characteristics, diet history, eating habits, and intake frequencies of six food groups by survey. A total of 94 women among the subjects participated in the pre and post nutrition knowledge evaluations and anthropometric data assessment. After the program, body weight, body mass index (BMI), and waist circumference significantly decreased. Further, % of body fat decreased, but not significantly. BMI significantly decreased (p<0.001) from 25.14 to $24.80kg/m^2$, and waist circumference significantly decreased (p<0.001) from 79.72 to 77.63 cm. The nutrition knowledge scores of subjects significantly increased (p<0.001) from 8.01 to 9.03. However, there was little change in employment. These results suggest that the nutrition-exercise education program may improve obesity index and nutrition knowledge. However, it is necessary to develop a specialized weight control program for workers.
