BACKGROUND Unsafe behaviors are main causes of accidents mostly influenced by personal characteristics, social environment and also individual biorhythm cycles. This study was carried out to find out whether personality traits and biorhythm could affect the incidence of unsafe behaviors among city bus drivers. METHODS This cross-sectional study was conducted on 224 bus drivers in Shiraz, Iran...

BioRhythm is an interactive bio-feedback installation controlled by the cardiovascular system. Data from a photoplethysmograph (PPG) sensor controls sonification and visualization parameters in real-time. Biological signals are obtained using the techniques of Resonance Theory in Hemodynamics and mapped to audiovisual cues via the Five Element Philosophy. The result is a new media interface uti...

Data on occurrence of suicide from a population of 993 Veterans Administration hospital patients were used to test the validity of the Fliess-Swoboda Biorhythm Theory. Using a novel approach to analysis, semicritical day types were included. Sixty-four day types were generated and divided a priori into five categories which corresponded to predictions of increased or decreased suicides accordin...

Evidence of a periodic biorhythm is retained in tooth enamel in the form of Retzius lines. The periodicity of Retzius lines (RP) correlates with body mass and the scheduling of life history events when compared between some mammalian species. The correlation has led to the development of the inter-specific Havers-Halberg oscillation (HHO) hypothesis, which holds great potential for studying asp...

Biorhythm is one of the latest topics in the field of identifying mind’s ergonomics. Of all the performances with which biorhythm deals is the physical performance. The purpose of present research is to study the effect of physical cycle of biorhythm on the designated factors of physical fitness among teenage volleyball players in the city of Qom. In the present field research, 30 people were...

Sleep problems and circadian rhythms disturbances are common in many psychiatric disorders, with the most often-reported sleep problem in most cases being insomnia. In this paper, the main findings about sleep disturbances(features and therapy) and other biorhythm disturbances (biological timekeepers, CLOCK genes, GSK3, melatonin, hypothalamo-pituitary-adrenal axis, body temperature) are review...
