Effects of the environment of a simulated shelter in a gymnasium on sleep were investigated in 20 healthy school-aged children. Measurements were obtained during a one-night stay in a school gymnasium during the summer (C). Activity levels were monitored using a wrist actigraph, and temperature and humidity of the bedrooms in the subjects' homes were monitored from 3 days before to 3 days after C. The subjects were asked to provide information regarding subjective sleep estimations and thermal sensations. The results for the days before C (BC), C, the first day after C (A1), and the second day after C (A2) were compared. The bedroom temperature was significantly lower on BC than on the other nights. No significant difference was observed in bedtime, whereas wake-up time was significantly earlier on C and later on A1 than on the other nights. Total sleep time was significantly decreased on C (3.6 h) and increased on A1 when compared to the other nights. Daytime nap was significantly increased on A1 when compared to the other days. Subjective estimation of sleep quality was decreased and sweat sensation before sleep was increased on C when compared to the other nights. The main reason for sleep disturbances on C was heat. These results indicate that the environment of the simulated shelter in the gymnasium severely disturbed sleep in children. The resulting loss of sleep was compensated for by increased nocturnal sleep time and daytime napping on the next day.
This study examines the effectiveness of a communication skill training based on a coaching theory for public health nurses (PHNs) who are engaged in Japan's long-term care prevention program. The participants in this study included 112 PHNs and 266 service users who met with these PHNs in order to create a customized care plan within one month after the PHNs' training. The participants were divided into three groups: a supervised group in which the PHNs attended the 1-day training seminar and the follow-up supervision; a seminar group attended only the 1-day training seminar; a control group. The PHNs' sense of performance expectancy, and user's satisfaction, user's spontaneous behavior were evaluated at the baseline (T1), at one month (T2), and at three months (T3) after the PHNs' training. At T3, the PHNs performed a recalled evaluation (RE) of their communication skills before the training. The PHNs' sense of performance expectancy increased significantly over time in the supervised group and the control group (F = 11.28, P < 0.001; F = 4.03, P < 0.05, resp.). The difference score between T3-RE was significantly higher in the supervised group than the control group (P < 0.01). No significant differences in the users' outcomes were found.
We aimed to examine sleep in shelter-analogue settings to determine the sleep and environmental conditions in evacuation shelters. A summer social/educational event was conducted in an elementary school, wherein children and their parents (n = 109) spent one night in the school gymnasium; a total of 15 children and 7 adults completed the study. Data were recording using wrist actigraphy and questionnaires, from two days before the event to two days after the event. During the night in the gymnasium, sleep initiation in the children was found to be significantly delayed, whereas adults did not show any significant change in actigraphic sleep parameters. Although 57% of adults complained of stiffness of the floor, only 7% of children had the same complaint. The nocturnal noise recorded at four locations in the gymnasium showed that the percentage of 1-min data epochs with a noise level >40 dB ranged from 53% to 74% during lights-out. The number of subjects that woke up during the night showed a similar pattern with the changes in the noise level. The changes in sleep might represent event-specific responses, such as to a noisy environment, and the different complaints between adults and children could be useful in shelter management.
