This paper examines the effects of shift work on the mental state of factory workers. As an indicator of the workers' mental condition, the authors used a scoring system (referred to below as the 'depression tendency score') based on the SRQ-D investigative report. The depression tendency score of the men was higher among the shift worker group than among the regular day worker group (p < 0.01)...

In this paper, it is proposed the information delivery system that the transmission signal embraces together the wide-area information and the local area information. The distant user from the base station receives the wide-area information only and the nearby user receives together the widearea information and the local-area information. The proposed system uses the code shift keying(CSK) for ...

This study was to evaluate whether sleep-related autonomic function in nurses recovers during their days off following a rapidly rotating, clockwise shift schedule. Ten rotating-shift nurses and ten regular morning-shift nurses were included. Nurses slept at home and were allowed to sleep and wake spontaneously. For the rotating-shift workers, ambulatory polysomnographic recordings were taken d...

In a review of the medical and social aspects of shift work Taylor (1970) points out that many of the most important questions relating to shift work remain to be answered. One of these questions, on which evidence to date has been almost nonexistent, is the effect of a twelve-hour shift system on absence attributed to sickness. An opportunity to examine this occurred in 1973 when a change was ...

This paper reviews a number of studies which have presented results on the association between shift work and cardiovascular disease. It is suggested that many of the early studies suffer from methodological flaws which render them difficult to interpret. In studies in which incidence of disease has been computed and related to exposure to shift work, the results indicate a higher risk for card...

Following the implementation of the European Working Time Directive Regulations, almost all junior doctors in the UK now work full night-shifts. An RCP 50-member working group was established to develop a practical guide to help junior doctors prepare, survive and recover from working night shifts. The guide, set out in this paper, examines the evidence concerning the hazards of shiftwork, and ...

Shift work can be attributed to some of social and health problems in working community. In this study an attempt was made to study the sleep and wakefulness patterns in nurses engaged in rotational and non-rotational shift work in a hospital through sleep charts. It was observed that non-rotational workers enjoyed more frequent and longer naps and had less disturbances in their sleep patterns ...

OBJECTIVE To determine attention performance of medical students after sleep deprivation due to night shift work. METHODS Prospective cohort design. All seventh, eighth and ninth semester students were invited to participate (n= 209). The effectiveness and concentration indices (d2 Test for attention, dependent variable) from 180 students at 3 evaluations during the semester were compared. Ei...
