A Survey on BeReal among University Students: Focus on Learning Motivation and Privacy Consciousness

by Futa Yahiro - October 24, 2024

The purpose of this study was to determine university students' thoughts on the use of BeReal. After clarifying these ideas, we compared and examined the differences in learning motivation and privacy consciousness by use, non-use, and differences in thinking. The survey population consisted of 368 university students. The survey included “items on thoughts about using BeReal”, “Learning Motivation Scale”, and “Privacy Consciousness Scale”. The results of this study indicated that BeReal is becoming more common among university students, and that many of them are willing to contribute during class.Also, It revealed that university students who use BeReal tend to be less learning motivation than those who do not use BeReal. Furthermore, the group that posts BeReal during class tends to have lower awareness of and behavior to maintain their own privacy than the group that does not post BeReal during class.

Methodological examination of methods for analyzing factors that affect home team advantage: from univariate analysis to multivariate correlation models and causal models

by Yasufumi Ohyama - October 7, 2024

While most researchers agree that home advantage (HA) exists in soccer, baseball, field hockey, basketball, and other sports regardless of whether they are collegiate or professional, there is no common view on the relationship between “travel,” “familiarity with the game environment,” and “spectator effect” and the factors derived from them and home advantage. However, there is no common view on the relationship between “travel,” “familiarity with the game environment,” “spectator effect,” and their derived factors, and HA. In other words, unless there are new factors that are not addressed here, it is more appropriate to think of the factors that affect HA, which clearly exists, as “multiple factors that relate to each other and affect it comprehensively,” rather than as “factors that affect it independently. Therefore, a possible methodology for examining HA factors is the use of multivariate analysis, such as multiple regression analysis or logistic regression analysis. Then, when illustrating the findings obtained from correlation analysis, one-way arrows are used to show the relationship between the factors, and the focus shifts from the correlation relationship to the search for causal relationships. When the scope of correlation analysis is extended to include causal relationships, path analysis is used to examine not only direct effects but also indirect effects. Furthermore, as a natural development of the methodology of causal analysis, a new direction is considered to be the analysis of covariance structure, which examines the causal relationships between factors, rather than only the observed variables.

Evaluation of Revitalization Measures for Central City Areas Considering Changes in Human Flows

by Daisuke Kamiya - September 9, 2024

In recent years, a declining population and an aging and decline have led to a reduction in the vibrancy and economic activity of the city. Various regional cities have taken measures to revitalize their central city areas. However, they have yet to develop a method to quantify the effects of these measures. In this study, using a device equipped with Internet of Things (IoT), we obtained basic data on the number of visitors before the COVID-19 to quantify pedestrian traffic along Kokusai Street. Our findings revealed that the implementation of revitalization strategies led to a notable increase in the number of individuals visiting the area, as well as in the average duration of their stay. This suggests that the implemented measures have the potential to contribute to the revitalization of the area, thereby fostering the creation of a vibrant town center.

An Inquiry-Based Learning Support System for Children in Sports Acquisition Processes

by Masayuki Yamada - February 28, 2024

This study examined an inquiry-based learning support system for children in sports acquisition processes and describes the characteristics of a case study on the long-term collaborative process of children’s forward and backward cycle practices on horizontal bars. We analyzed 18 horizontal-bar practices for two elementary schoolchildren who had not succeeded in their backward cycle for approximately half a year. They were required to make practice plans collaboratively to succeed in their forward and backward cycles. To support their practices, we provided them with “HDMi (HDMi is the name of a system we developed in the past.),” which was developed to support reflecting on one’s physical movements using movies. The movies were also used for discourse analysis to determine where the children focused, and OpenPose software was used for motion analysis to examine how the children’s actions improved on a horizontal bar. Both the HDMi and the discourse analysis suggested that two children selected their focusing points for their practice and they gradually became referring to “move toes toward opposite side of the bar” in the periods of practices. However, the motion analysis revealed that the focused points and actual movement of the body did not match completely.
