The purpose of this paper is to propose that the measurement of salivary amylase activity is an effective index to evaluate the stress of a ship navigator for safe navigation training and education.

    Design/methodology/approach

    Evaluation comes from the simulator and actual on-board experiments. The subjects are real captains who have unlimited licenses and cadets who are senior students at Kobe University, navigation course. Stress is evaluated for several situations where a ship navigator makes a lot of decisions, in this case in a narrow passage, entering a port and leaving a port.

    Findings

    Salivary amylase activity occurs when a ship navigator makes a decision regarding ship handling and collision avoidance. By measuring salivary amylase activity when a student is under duress, cadets' ship-handling training can be evaluated while onboard a vessel.

    Research limitations/implications

    Future research will develop cross-indices with the salivary amylase activity and other physiological indices (nasal temperature and heart rate variability (R-R interval)), complementary to each other. The salivary amylase activity registers the stress quickly on the spot. Then the nasal temperature and R-R interval registers the trend and the quick response to the stress (mental workload).

    Practical implications

    The paper describes an effective index which is useful for evaluating a ship navigator's stress for safe navigation.

    Originality/value

    Ship navigator's skill and cadet's on-board training have been evaluated according to performance and a questionnaire as a quantitative evaluation; moreover, stress is evaluated using salivary amylase activity.
