The aim of this study was to investigate differences in heart rate variability (HRV) reflecting the function of autonomic nervous system (ANS) and psycho-physiological strain associated with normal and extended work shifts in nursing work. Complete data were available from 51 female nurses with a mean age of 40 yr, and based on two comparable 36-h HRV measurements supplemented with a questionna...

In this work, the optical absorption near the fundamental absorption edge of co-evaporated Ce0 -V20 films is studied. It is found that the fundamental optical absorption in these materials is sharp more like that expected for crystals. It is also found that as the V O content increases, the edge becomes less sharp and shifts towards higher wavelengths

Little is currently known about the physical activity patterns of workers in physically demanding populations. The aims of this study were to (a) quantify firefighters' physical activity and sedentary time within (2-h periods) and across planned burn shifts; and (b) examine whether firefighters' activity levels during one shift or 2-h period was associated with their activity levels in the foll...

Twelve-hour shifts are a popular alternative to 8-hour shifts as many consider these shift arrangements superior in terms of facilitating a better social and family life. This view is largely based on anecdotal evidence, however as few studies have examined longitudinal relations between work/non-work conflict and shift length. Using self-report data from 137 machine operators this study examin...

conclusions based on the study results, making plans to promote mental aspect of nurses, focusing on family foundations like marriage, reducing and distributing working hours, and decreasing night shifts hours of nurses could reduce their depression and improve their quality of life. results according to the final model yielded from path analysis, the most important factors contributing to depr...

OBJECTIVES The aim of this study was to explore the detrimental effects of working a varying pattern of 8-hour shifts on quality of sleep, general health and work performance. SUBJECTS AND METHODS The Arabic version of the Pittsburgh Sleep Quality Index (PSQI)and 2 self-administered questionnaires were used to assess quality of sleep, work performance and general health in a sample of 200 mal...

12-hour shifts are quickly spreading in Europe. From our multivariate analysis concerning 25,924 European nurses, including twenty explanatory variables simultaneously, we found that work schedule itself is not a major determinant factor. Nurses aim to choose or accept night shifts or 12-hour shift in order to reduce their work/home conflicts, however, at the expense of the patient's safety, as...
