In the COVID-19 era, it was implemented to be used as a basic material for setting the direction of learning support and student guidance for university institutions and professors who are experiencing confusion. The purpose of this study is to compare the actual status of daily-routines of COVID-19 period, general semester period, and vacation period, and to examine whether there is a difference between the period of general semester and COVID-19 period, and whether there is a difference in daily use of COVID-19 period depending on grade. For this reason, a questionnaire survey was conducted from April 23 to 29, 2020, targeting students of University A, which is a small-scale technical centered university in the region, and 754 students answered. As a result of the study, first of all, when we looked at the trends in the use of daily-routines by period of general semester, vacation period, and COVID-19 period, the trends of the general semester period and COVID-19 period were similar in the areas of learning and self-development. Second, there were statistically significant differences in sleep, relaxation, learning and other areas between the period of the general semester and the duration of COVID-19. Third, there were statistically significant differences over grade in relaxation, learning, development, and other areas.

The pandemic over the past three years has brought drastic changes in our lives, and those changes are now becoming a natural part of our daily lives. Daily life and economic activities based on online, such as video conferencing, remote classes, telecommuting, and online streaming services, have become daily routines after Corona. And the result of rapid development of communication and graphic technology is the metaverse. Therefore, the purpose of this study is to study the possibility from the perspective of public design for the correct use of the metaverse space of local governments. To this end, in this study, big data analysis was performed on 'local government', 'public design', and 'metaverse'. As a result of this study, we should actively use metaverse with high topic and potential as a space for local governments' promotion or discussion as a means to restore the reliability of local governments and overcome negative perceptions. In addition, it is necessary to actively reflect public design in order to increase the public reliability of local governments' metaverse.

Objectives: This study aimed to develop educational content for a smartphone app on oral muscle training and examine its effects on the elderly population. Methods: A total of twelve training sessions were delivered through the smartphone app over a six-week period, from late August to early October 2023. Each session lasted approximately 60 minutes. Participants were followed up after the program. Results: The experimental group showed significant improvements in oral health before and after using the smartphone app. These improvements included decreased dental plaque (p<0.05) by 0.69 units, decreased gingivitis (p<0.001) by 0.99 units, decreased tongue plaque (p<0.01) by 1.11 units, increased salivary secretion rate (p<0.001) by 0.73 units, increased hard palate strength (p<0.001) by 5.25 units, and increased soft palate strength (p<0.01) by 6.82 units. Compared to the control group, the experimental group showed significant improvements in dental plaque (p<0.001), gingivitis (p<0.001), and tongue coating (p<0.01). Conclusions: This study found that oral muscle strengthening training using the smartphone app effectively improved oral health in the elderly. The developed app content has the potential to be a valuable tool for promoting oral health in this population within their daily routines. However, further efforts are needed to ensure clear communication and effective utilization of the training program through user training or educational materials.
