OBJECTIVE: Operator's movements are one of the areas where variability is undesirable. Vehicle driving is probably the most frequent operator movement in society where errors can result in serious social, medical and economic consequences. In this article we focused on the influence of moderate alcohol intoxication (less then 1.0 g/kg) on right hand movement variability during manual gear selection and on driving ability. METHODS: The test took place in a laboratory setup in a passenger vehicle simulator. Simulated traffic lights were used to stop the car and hand movement was measured by kinematical analysis with the use of a motion capture system. RESULTS: Large variability in blood alcohol concentrations were observed as well as large intra-individual hand movement variability and reaction time to visual stimulus. DISCUSSION: The findings are somewhat ambiguous. Research outcomes did not confirm the hypothesis about the impact of moderate alcohol intoxication on movement variability. On the other hand, in some cases the observed data indicate critical behavior regarding safe driving and response to particular traffic situations.

There is a longstanding empirical rule that people who commit suicide rarely shoot through their clothing, but rather put it aside to expose the nude skin. Signs of shots through clothing have always been considered suspicious, raising presumptions of the presence of an abettor. Our report, based on a retrospective study of fatal suicidal firearm injuries from the years 1980 to 2007, points out that suicide victims only rarely remove clothing from the site of the future entry wound. The report covered 43 cases with fatal gunshot wounds in the area of the thorax, with only four persons (9%) removing the clothing present in the area of the subsequent self-inflicted wound. Defects present on the clothing of a victim cannot, therefore, be understood as an absolute criterion for disproving the possibility of suicide, and nor do they necessarily indicate an unfortunate accident or homicide. If, however, the suicide victim removes the clothing from the area of the future wound, then this is almost always an indication of suicide.
