    Longitudinal relationships between cardiovascular events, risk factors, and time-dependent sleep duration

       Background: Although many studies have evaluated the relationships between sleep duration and cardiovascular (CV) events/risk factors, longitudinal associations with time-dependent sleep duration have not been adequately assessed. Methods: A retrospective, longitudinal study was conducted involving individuals aged 20 years or older that received annual health check-ups at St. Luke’s International Hospital from 2005 to 2010. Data collection included self-reported demographic, clinical and health habit information (including sleep duration; < 6, 6–7, 7–8, ≥ 8 h), baseline examinations, and laboratory measures for each year. We conducted mixed effects analyses to examine the associations between non-fatal CV events, risk factors, and time-dependent sleep duration longitudinally. Results: Of the total of 31,830 participants enrolled, 70.1% of participants changed their sleep dura­tion, and 365 participants experienced CV events during follow-up periods. Compared to those reporting 7–8 h of sleep, those reporting less than 6 h of sleep were significantly more likely to experience non-fatal CV events (odds ratio [OR] 1.78; 95% confidence interval [CI] 1.03–3.07; p = 0.04), but other groups were not (OR 1.12; 95% CI 0.70–1.77; p = 0.64 for 6–7 h and OR 1.22; 95% CI 0.68–2.23; p = 0.50 for ≥ 8 h). The shortest sleep duration was associated with a higher likelihood of obesity/overweight status (OR 1.49; 95% CI 1.32–1.69; p < 0.01). Conclusions: Individuals reporting less than 6 h of sleep were significantly more likely to have non-fatal CV events than those reporting 7–8 h of sleep. For the risk factors, short sleep duration was associ­ated with obesity/overweight status

    Verification of Japanese language classes that foster logical thinking skills

    In this study, based on the hypothesis that it is effective to develop logical thinking ability in the Japanese language department, we will examine the reading comprehension and instruction of "strategy" at low, middle and high levels. By conducting lessons based on these hypotheses, the types of logical thinking and the characteristics of developmental stages were clarified. One is logical thinking as a process of interpreting the logic contained in the content of the story. The other is the logic of linguistic expression, or logical thinking as a process of interpreting the narrator or author of a story
