Background: Bus driving is a mentally demanding activity that requires prolonged attention to ensure safety. The aim of the study was to assess mental fatigue caused by driving a public bus and to find a profile of workers at higher risk. Methods: We evaluated changes of critical flicker fusion (CFF) (index of central arousal) and heart rate variability (HRV) (index of autonomic balance) in a 6-hour driving shift on a real route, in 31 professional bus drivers, and we tested the influence of personal factors such as sleep quality, BMI, and age. Paired t-test was used to test differences of CFF and HRV between both initial and final phase of driving, while multiple linear regression tested the influence of personal variables on the indexes of mental fatigue. Results: Results showed that CFF significantly decreased after 6 hours of bus driving (41.91 Hz, sd 3.31 vs. 41.15 Hz, sd 3.15; p = 0.041), and heart rate significantly decreased in the final phase of driving, with respect to the initial phase (85 vs. 78 bpm, p = 0.027). Increasing age (beta = -0.729, p = 0.022), risk of obstructive sleep apnea syndrome (beta = -0.530, p = 0.04), and diurnal sleepiness (beta = -0.406, p = 0.017) showed a significant effect on influencing mental fatigue. Conclusion: Elderly drivers at higher risk of sleep disorders are more prone to mental fatigue, when exposed to driving activity. Monitoring indexes of central arousal and autonomic balance, coupled with the use of structured questionnaires can represent a useful strategy to detect profile of workers at higher risk of mental fatigue in such duty.

The purpose of this study was to investigate different attitudes of officers depending on system of collaborative practice between traditional Korean medicine and western medicine. A total of 103 officials were surveyed using structured questionnaires. Data were analyzed using descriptive statistics, ${\chi}^2$ test with the SPSS program. Use of oriental medicine clinic was significantly higher and use of general hospitals was significantly lower in a group of users (p=.021). Higher rates of disease status were found in a group of users (p=.024). 'Overcome limits of Traditional Korean Medicine and Western Medicine' and 'collaborative practice would bring benefits' as the reasons of using collaborative practice between Traditional Korean Medicine and Western Medicine showed higher rates (p<.001). It showed high interests in collaborative practice between Traditional Korean Medicine and Western Medicine in two groups, but higher rates of prospect of collaborative practice between Traditional Korean Medicine and Western Medicine revitalization were found in the group of users. Also, more than 60% of the officers showed positive attitudes in the system of the collaborative practice. Therefore, correct researches on actual conditions about collaborative practice between Korean and Western Medicine and positive and negative aspects of this collaborative practice pointed by candidates need to be considered in order to improve candidates' health condition.
