    Relationship between physical education in the first year of university and exercise habits and physical and mental health in the following spring

    by Takehira Nakao - April 1, 2022

    The present study examined the relationship between taking physical education and health-related courses in the first year of university and the acquisition and maintenance of exercise habits and physical and mental health in the student’s second year. The study population consisted of university students was 2,483 in FY2017 and 2,352 in FY2018. Of these, the 2,293 students (1,744 men, 18.5 ± 1.0 years old; 549 women, 18.6 ± 1.0 years old) who responded to the self-administered questionnaire survey on daily living habits in both years were included in the analysis. The results showed that taking physical education and health-related courses in the first year was significantly related to exercise habits the following spring. The results also suggested that these courses were more strongly related to mental health than physical health. In addition, men were significantly more likely to acquire a new exercise habit and had more improved mental health. In the future, it is necessary to clarify the causal relationship between taking physical education and health-related courses and exercise habits and the maintenance and acquisition of physical and mental health, in addition to developing effective support methods for students who dislike gender differences and exercise.

    Proposal of Rubric for Information Security Education Materials

    by Daisuke Saito - April 20, 2022

    This study proposes a generic rubric that can be used as an assessment axis for information security educational materials regarding existing computer science education evaluation standards to assess the learning effectiveness of information security educational materials aimed at young people. The proposed rubric includes items such as “understanding of cyber security” and “understanding why passwords are necessary,” and five-level learning objectives are defined for these items. Furthermore, the proposed rubric was used to assess the existing information security educational material “Hajimete no Joho Security (Learning First Information Security in a Different World)” using Minecraft. The proposed rubric was mapped to the learning contents of the teaching material as an assessment method, and the learning effectiveness of the teaching material was measured using Minecraft with the cooperation of a community center project in Sayama City in Japan. Therefore, we were able to evaluate the learning effects using the proposed rubric.

    Organizational Ambidexterity and Firm Performance: Effect of Two Types of Exploitation on Japanese Video Game Industry

    by - March 15, 2022

    Recent organizational ambidexterity studies have discussed the importance of achieving a balance between Exploration and Exploitation. However, existing studies have not distinguished the detail of exploitation; this study categorizes exploitation as ‘Repetitive Exploitation’ and ‘Incremental Exploitation.’ Our study contributes to ambidexterity studies by analyzing the impact of a combination of both these types of exploitation and exploration on a firm’s performance. We used 647 observations from Japanese video game industries between 1997 and 2019 for panel data analysis. In line with existing studies, we proved that firm performance increases when a balance between exploration and exploitation is achieved. At the same time, we found that firms with a lower exploration performed better when the rate of incremental exploitation was high. The results of our study suggest that even when the firm's ambidexterity is imbalanced, different results can be expected when both types of exploitation are considered. The Study has implications for organizations to improve their performance.
