    The purpose of this study was to investigate the associations of lunch-taking habits with the lifestyles and health conditions among home-delivery drivers. In June 2016, 447 home-delivery drivers completed a cross-sectional self-report questionnaire that included items about life rhythms and eating habits. Data from 351 participants were analyzed. The participants were divided into three groups (group 1: those who did not have lunch, group 2: those whose lunch time was before 14:00, group 3: those whose lunch time was after 14:00). Group 1 (54 participants, 15.4%) had a higher rate of those skipping breakfast every day, a lower rate of those eating well-balanced meals every day, and higher scores of depression and anxiety. Group 3 (67 participants, 19.1%) had a higher frequency of overeating at dinner, taking a later dinner, later bedtimes, and higher scores of depression than Group 2 (230 participants, 65.5%). These results showed differences in lifestyles and stress reactions based on lunchtime habits.

    The panic occurring while driving is considered to be a factor of the major accidents such as those due to unintended acceleration. There are few studies that examined the panic conditions while driving experimentally. A highway driving experiment using a driving simulator was carried out by 18 participant (13 males and 5 females). The task during driving was to avoid an obstacle by steering operations. After repeating many trials in which an evasion instruction was shown with a sound or a sign presented one second before an obstacle appearance (context-trials), trials without such instructions (target- trials) revealed various action slips related to a panic situation and true panic behaviuor occurred frequently. The list of panic behaviours and action slips which occurred experimentally was created. And panic-like behaviours were ranked based on the frequency and importance. Moreover, the relations between a driverʼs characteristics and panic-like behaviours were analyzed. It became clear that the rank value of panic actions in elderly drivers was higher as compared with that of the other age group. It was thus presumed that the disagreement of a driverʼs prediction and an actual situation should be an important factor of panic behaviour. It was considered that the basic performance of driving support equipment not to produce the driverʼs overconfidence to the equipment was important.
