Examination of experienced university student athletes of Olympic athletes in Japan

This study aimed to clarify how many university student athletes were among the athletes who represented Japan at the London Olympics (2012), Rio de Janeiro Olympics (2016) and Tokyo Olympics (2021); their result; and the faculties they belonged to in their universities. Athletes registered at the above mentioned competitions who were current university students or who belonged to a university in the past (including dropouts) were included in the survey. The result of this study shows that academic clustering is becoming increasingly customary.

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

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.

Nature versus Artifacts Body: One-Leaf Hyperboloid Type, Pair-Map Microcosm and Nested Economics

Toward digital-era, there is more increasing the portion of artifacts on the earth, and is attainable to the global environment of nature versus artifacts bodies. At the paper, we first suppose One-leaf Hyperboloid and the typical cases:Social (or enterprise) and Physical bodies as the base of nature vs. artifacts bodies. Second, the traditional pair-map is here developed, is semi-finalized at a generalization including Nash’s zone, and its 3D-like body is visually embodied as the two illustrations. Third, for a fractal(nested) mother of pair-map and its Nash’s zone, the shared equilibrium problem of 3D-type is discussed on the Trickle-down effort vs. Modern money theory (up) at Mt. Fuji type in the economic society. Finally, it is remarked that the latter might be better than the former at income distribution.

A fundamental examination of the attentional function in the rhythm game

This study aimed to clarify the effect of the rhythm game "Osu!" on attentional function and its factors. Participants wore an electroencephalograph and played "Osu!” for 10 minutes (four games), and the Trail Making Test was performed before and after the games. As a result of the analysis focused on the frequency of the games, only the "high frequency group" showed an effect on attentional function. From the results, it can be inferred that rhythm games can improve attentional function and can function as a training tool for game users. The results also suggest that rhythm games can be used as a health-promoting tool owing to their ability to improve attentional function.

Impact on evaluation of Viewpoints to assess the positioning on half-court defense in the basketball

While there are some desirable and some not-so-desirable half-court positions in basketball, the "desirable positioning" may not always be clearly determined due to the values of the coach or manager. The most important factor in this is the "point of view". Therefore, the purpose of this study is to examine the perspectives that influence the evaluation of positioning in half-court defense for university teams be-longing to the first and second divisions of the Basketball Federation. A total of 192 players (110 male players and 82 female players) from university teams in the first and second divisions of the K-Student Basketball Federation were included in the study. As a result, the perspectives of the reasons for the decisions obtained in the descriptive form have been classified into the following categories: "Weak-side defensive position," "Strong-side defensive position," "Ball man defensive position," "General defensive position," "Defensive position related to play selection," "Defensive position related to coordination," and "Defensive position related to situational judgment. "The defensive positions were classified into seven categories: defensive positions related to situational viewpoints.
