    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.

    The purpose of this study was to investigate the psychological effects of arousal levels in esports players during a racing-game under positive and negative ion environments. Participants (10 male) who belonged to the collegiate esports team were recruited. The influences of positive and negative ions were evaluated in a randomized, crossover, and placebo-controlled double-blind design. Each participant completed two experiments within a 4-week interval. Two experimental environments were used: positive and negative ions filled up the atmosphere (PNI), and a control (CON) condition. For the performance task, a car-racing game was adopted. Arousal state was measured by the Two-Dimensional Mood Scale (TDMS) and an electroencephalogram (EEG). Results indicated that the EEG level was significantly higher in PNI than CON condition. Also, the PNI had a significantly higher performance on the gaming task than the CON condition. The present study demonstrated the beneficial effects of positive and negative ion environments on esports players.
