Sleep is systematically modulated by chronotype in day-workers. Therefore, investigations into how shift-work affects sleep, health, and cognition may provide more reliable insights if they consider individual circadian time (chronotype). The Munich ChronoType Questionnaire (MCTQ) is a useful tool for determining chronotype. It assesses chronotype based on sleep behavior, specifically on the lo...

The "Bergen Shift Work Sleep Questionnaire" (BSWSQ) was developed to systematically assess discrete sleep problems related to different work shifts (day, evening, night shifts) and rest days. In this study, we assessed the psychometric properties of the BSWSQ using a sample of 760 nurses, all working in a three-shift rotation schedule: day, evening, and night shifts. BSWSQ measures insomnia sym...

OBJECTIVES To investigate the factors associated with the timeliness of electronic nursing documentation using the entry time on the Electronic Medical Record (EMR) system. METHODS As a retrospective study, data were extracted from January 1 to February 28, 2014 from a hospital EMR system and a nurses' personnel information system. The timeliness of instances of nursing documentation was cate...

The ability to be synchronized by light-dark cycles is a fundamental property of circadian clocks. Although there are indications that circadian clocks are extremely light-sensitive and that they can be set by the low irradiances that occur at dawn and dusk, this has not been shown on the cellular level. Here, we demonstrate that a subset of Drosophila's pacemaker neurons responds to nocturnal ...

The purpose of this study was to compare the thermoregulatory responses during exercise in the morning rise (0900 h) and evening fall phases (2000 h) in circadian variation of body temperature. Five healthy volunteers performed bicycle exercises at 30% and 60% of maximal aerobic power (VO2max) at 26 degrees C with a relative humidity of 50%. Whole-body sweat rate (SR), rectal (Tre), mean skin (...

In Japan, the most common reason for medical errors is a lack of cross-checking. To prevent errors, efforts to strengthen cross-checking behaviors are being adopted. However, time pressures also lead to errors, and increasing cross-checking activities leads to an increased workload and even greater time pressures. The purpose of this study was to identify working conditions that lead to time pr...

Ostberg, 0. (1973). BritishJournalofIndustrialMedicine,30,341-351. Interindividual differences in circadian fatigue patterns of shift workers. Data from 37 computer operators and outputhandlers, working on discontinuous 8-16-24 alternating shifts, were collected in the morning, evening, and night shifts during a one-year period. The study was directed to the interindividual diTerences in the wo...
