Predictive head-movements during automobile mirror-sampling.

Eye-head response patterns of 3 novice, 3 young experienced, and 3 mature drivers were recorded by television cameras as they sampled their vehicle's mirrors just prior to making freeway left-lane changes, right-lane changes, and entrance merges. Eye-head responses were called "classical" if the eyes moved before the head and "predictive" if the head moved before the eyes. Drivers made about twice as many predictive responses as classical ones. Data suggested that the rate of making predictive head-movements was 90 msec. and that of classical responses was 45 msec. Latency was not related to the amount of driving experience.

Machiavellianism scores and self-rated performance of automobile salespersons.

Machiavellianism (Mach-B) was positively correlated with self-reported number of vehicles sold and income in two samples of 80 car salespersons. The Mach-B scale showed higher internal consistency and significant relationship with sales performance. The Mach IV scale, used for one of two samples, showed low internal consistency and a nonsignificant relationship with performance. The results provided partial support for earlier findings. Research designed to clarify this finding is required.

Strategy for health and safety management at an automobile company--from the prevention of low back pain to Toyota's Verification of Assembly Line (TVAL).

This paper reports on a strategy to improve and renovate assembly lines, including countermeasures to prevent low back pain during the past two decades at Toyota Motor Co. Since 1975, there have been problems with low back pain at Toyota's vehicle assembly lines. To deal with these low back pain problems, it was necessary to determine their causes and to quantitatively evaluate the burden on workers. For this purpose, functional burden indexes were developed, that is, a posture burden point and a weight burden point were determined to assess the load on the low back, and a low extremity point and a squatting posture point were determined to assess the burden on the leg. The functional burden index, however, could be applied only to specific human functions, not to human functions in general. Since there are about 400 kinds of working patterns in vehicle assembly lines, comprehensive burden index was required to estimate overall burden of such work. Thus, we developed Toyota's Verification of Assembly Line (TVAL), an index for assessing the physiological stress of an assembly line work, in which an equivalent bicycle ergometer workload is calculated from electromyograms taken of 20 different muscles under actual working conditions. At present, TVAL is used to measure physiological burden of assembly work in order to give priority to improvements, and to objectively demonstrate the effects of such improvements at Toyota.

Drinking reasons, drinking locations, and automobile accident involvement among collegians.

Multiple regression analysis was used to examine the relationship of five drinking reason factors to drinking locations and consumption variables within a random sample of drinking college students surveyed by telephone. Hypotheses relating self-reported accident involvement after drinking and two specific reason factors - Opposite Sex/Drunkenness and Pleasure - were tested. Both Pleasure and Opposite Sex/Drunkenness were directly related to quantity consumed and to drinking in several away-from-home locations. Opposite Sex/Drunkenness reasons and frequency of drinking in cars significantly contributed to identifying males who reported accident involvement following drinking.

Mortality studies of machining-fluid exposure in the automobile industry. II. Risks associated with specific fluid types.

Excesses of digestive and respiratory cancers have been reported previously in association with exposure to machining fluids, agents in widespread use as coolants and lubricants in machining operations. Previous studies have had limited power to distinguish the effects of the different types of machining fluids in use. In a cohort of over 30,000 workers employed at two automotive plants in Michigan, mortality patterns were studied in relation to exposure to each of the three major fluid types--straight oils, soluble oils, and synthetic fluids. Standardized mortality ratios were estimated for subgroups of the cohort ever exposed to each of the three fluid types, and Poisson regression analyses were used to assess trends in risk with duration of exposure. The data suggest modest positive associations between exposure to straight oils and rectal, laryngeal, and prostatic cancer and a negative association between soluble and synthetic fluid exposure and lung cancer.
