The purpose of this study is to identify the temporal and spatial characteristics of pass accuracy by utilizing the second processing data and official records collected from the 2018 FIFA World Cup Russia video data. For a total of 128 games, the success rate of passes based on the results of the game, passing time, and passing position was two-way ANOVA with repeated measure. The results showed no difference between winning and losing groups, and no interaction effects were found for passing time and location. The difference in passing time was high in the first half, with the highest success rate in the middle of the first half (79.2%) and the middle of the second half (77.9%) in the 15~30 minutes and the 60~75 minutes. Pass success rates were in the order of defense-midfield area (83.9%), midfield-attack area (81.7%), defense area (70.6%) and attack area (61.1%). In conclusion, there was no difference in the passing success rate of the winning and losing teams depending on the characteristics of the relative competitive strength of the World Cup games, and it is believed that follow-up research is needed to analyze the game contents rather than the factors of the winning and losing in the future.

In the postmodern world, it is widely believed that being a fool or looking foolish can be more profound and unique than being smart and serious. Comic characters, or fool characters in comedy, have been used as basic tools to make people laugh in various cultures around the world. As such, this study will summarize the types of fool characters that have been depicted in plays and organize how they can be categorized in a culture of laughter as well as revealing their characteristics in performing arts. The ridiculous actions and words of fool characters fall outside the common dichotomy of wisdom and foolishness. This is significant and it is because the ways in which they act overturn the values that we consider to be truthful in the world of experience and contain wit and ridicule beyond the general knowledge. Also, it's worth pointing out that many comic characters that appear on TV shows are not all the same. To put it simply, each and every funny character has unique traits and these characters predictably change according to the times. In performing arts, a fool character's personality is displayed through his or her interactions with the audience. That is, on one hand, the character may or may not recognize himself as a fool, while on the other hand, the audience may regard the character as a fool or otherwise. Based on this background, the comic characters that appear in performing arts are categorized into four types and their features are discussed.

Biomedical signal measurement technology using images has been developed, and researches on respiration signal measurement technology for maintaining life have been continuously carried out. The existing technology measured respiratory signals through a thermal imaging camera that measures heat emitted from a person's body. In addition, research was conducted to measure respiration rate by analyzing human chest movement in real time. However, the image processing using the infrared thermal image may be difficult to detect the respiratory organ due to the external environmental factors (temperature change, noise, etc.), and thus the accuracy of the measurement of the respiration rate is low.In this study, the images were acquired using visible light and infrared thermal camera to enhance the area of the respiratory tract. Then, based on the two images, features of the respiratory tract region are extracted through processes such as face recognition and image matching. The pattern of the respiratory signal is classified through the k-nearest neighbor classifier, which is one of the statistical classification methods. The respiration rate was calculated according to the characteristics of the classified patterns and the possibility of breathing rate measurement was verified by analyzing the measured respiration rate with the actual respiration rate.

Interest in bodybuilding, such as weight training, has increased, but research on the motivation and behavioral intention of college students is lacking. Therefore, this study aimed to examine the motives of bodybuilding participation for college students and to find out the effect on behavioral intention by mediating the psychological resistance that occurs during the bodybuilding. As for the research method, a questionnaire was conducted on 250 users through an online survey from May 30 to June 10, 2023, and a total of 232 copies were used for the final analysis. As a result of the study, first, among college students' motivation to participate in weight training, the health-oriented type and self-development type had a positive effect on voluntary acceptance. Second, among the motives for participating in weight training, the home-oriented type was found to have a negative effect on opportunistic acceptance. Finally, voluntary acceptance had a positive effect on learning outcomes, and opportunistic acceptance had a negative effect on learning outcomes. Using the results of this study, it is expected that it will be helpful to understand the factors and policies in promoting the physical health of college students.
