This article describes the indirect effects of children’s road-crossing training on their parents’ attitude toward road safety. Parents trained their primary school children to stop at the curb, look right and left, and not to run on roads in school grounds. The parents responded to a questionnaire on their attitude toward road-crossing behaviors before and after the children’s training. The questionnaire result suggested that parents’ attitudes toward their road-crossing behavior changed with their children’s training on road crossing. Indirect effects of participating in road-safety training for children were discussed.'

This report describes designs of visual and auditory displays in a vehicle to mitigate drivers’ perceived annoyance with information presented by a vehicle-infrastructure cooperative safe-driving support system. Twelve drivers drove through a curve on which a vehicle had been parked on a sequence of driving simulator. Drivers were unable to see the parked vehicle but were given information on the collision risk. The results indicated that information presented by auditory tone mitigated drivers’ annoyance with the presentation in case of shorter times to collision with the parked vehicle. However, information presented by tones was associated with greater levels of driver annoyance for longer times to collision with the vehicle. Designs of the visual and auditory displays to mitigate the annoyance are discussed.

In previous work, we found that diesel exhaust particles (DEPs) suppressed allergen-induced inflammation in NC/Nga mice. In this study, we attempted pathway analysis using mouse lung DNA microarray data sets by ingenuity pathway analysis software ''KeyMolnet'' to clarify the molecular mechanism of the inflammatory response induced by DEP. As a result, we found that DEP suppressed the CC chemokine signaling pathway.
