Objectives: To explore differences in work performance based on the influence of sleep, work environment, and work-life balance. Methods: The datasets for this study were obtained from the Japan Civil Servant Study, which included 3478 participants (2199 men and 1279 women). Results: Belonging to the younger generation, high levels of support at work, fewer social contacts with friends, and a negative personality were independently associated with low work performance in both men and women. Poor sleep quality and job dissatisfaction were associated with low work performance in men but not in women. Workto-family conflict was associated with work performance in women. Conclusion: Interventions that target not only the overall measure but also account for sex-specific characteristics are important for improving work performance.

We organized regular, student-led activities in which medical students listened to patientsʼ narratives and engaged in casual conversation. This report reviews these activities, which were conducted 28 times between June 2020 and September 2022. Through the activities, we received feedback on feelings, new perspectives, and realizations that arose from both students and patients. Our findings suggest that listening to patientsʼ narratives helped students self-reflect and understand the patientsʼ perspectives. Moreover, interacting with students helped patients feel a sense of meaning and a new understanding of their illness.Keywords ：患者の語り(patientsʼ narratives) ，患者視点による病の理解 (understand patientsʼ point of view) ，学生の 省察(studentsʼ self-reflection) ，患者の有意味感(patientsʼ sense of meaning)
