Development and validation of the Japanese version of the Bedtime Procrastination Scale (BPS-J)
The BPS-J had sufficient validity and reliability. Further, eliminating Item 2 from the original version of the BPS strengthened the ability to survey Japanese daytime workers
Circadian phase advances in children during camping life according to the natural light-dark cycle
Background It is known that the circadian rhythm phase in adults can be advanced in a natural light-dark cycle without electrical lighting. However, the effect of advanced sleep-wake timing according to the natural light-dark cycle on children's circadian phase is unclear. We investigated the effects of approximately 2 weeks of camping life with little access to artificial lighting on children's circadian phases. We also conducted an exploratory …
Validity of an algorithm for determining sleep/wake states using FS-760 in school-aged children
BackgroundActigraphy is a method used for determining sleep (S)/wakefulness (W) by actigraph, a device equipped with a built-in accelerometer and an algorithm validated for each device. The S/W determination algorithm for the waist-worn actigraph FS-760 has been formulated for adults. However, the algorithm for children has not been established. The purpose of this study was to formulate an algorithm for discriminating S/W in school-aged children…
Is the use of high correlated color temperature light at night related to delay of sleep timing in university students? A cross-country study in Japan and China
BackgroundBlue-enriched white light at night has the potential to delay the circadian rhythm in daily life. This study was conducted to determine whether the use of high correlated color temperature (CCT) light at home at night is associated with delay of sleep timing in university students.MethodsThe survey was conducted in 2014-2015 in 447 university students in Japan and 327 students in China. Habitual sleep timing and type of CCT light at hom…
Implications of urbanism for the use of local news media
The Internet, a global computer network enabling people to send and receive information anywhere in the world, also functions as a local medium of communication. This study focuses on the role of the Internet in transmitting local news and examines the effects of community population concentrations as socio-ecological environments on the use of local news media consumed online and offline. Data from 1367 respondents across 156 Japanese communitie…
The Relationship Between Use of the Internet and Traditional Information Sources
This study examines how the spread of the Internet has affected Japanese people's information acquisition from traditional media or via traditional information channels. In particular, this study focuses on displacement and complementary effects and on devices for Internet access. Using representative data from Japan ( N = 1,179), the results show that Internet use via mobile phone has complementary effects on information acquisition from traditi…
Problemas vocais no trabalho
Dentre os trabalhadores, a categoria mais numerosa que faz uso profissional da voz é a dos professores. Este artigo teve por objetivo discutir, sob a óptica do professor, o uso da voz na prática docente e a prevenção de problemas vocais. Trata-se de um estudo de caso qualitativo-descritivo com 25 professores. Com base num roteiro semiestruturado foram realizadas entrevistas a fim de conhecer a relação dos sujeitos com suas vozes, a relação dos su…
Inhibition of Heart Rate Variability during Sleep in Humans by 6700 K Pre-sleep Light Exposure
Two different spectral analyses of heart rate (HR) variability (HRV) were performed on seven young male subjects to evaluate the effects of different color temperatures of light exposure (6700 K, 5000 K, 3000 K) before sleep on cardiac vagal activity. In investigating HRV, we used an ordinary fast Fourier transform (FFT) and coarse graining spectral analysis (CGSA), which selectively extracts random fractal components from a given time series. Th…
