  • In this study, physiological status of locomotive engineers were measured through EEG, ECG, EDA, PPG and respiration signals from 6 subjects to evaluate their arousal status during train operating. Existence of tunnels and mechanical vibration of train using 3-axes acceleration sensors were recorded simultaneously and were correlated with operator's physiological status. As the result of the analyzed subjects' physiological signals, mean SCR was increased in the section where more body movement is required. The RR interval was decreased before and after train stop due to the higher level of mental tension. The intensity of beta wave of EEG was found to be higher before and after train stop and tunnel section due to the increased mental arousal and tension. Therefore, it is expected that the outcomes of the physiological signals explored in this study can be utilized as the quantitative assessment methods for the arousal status to be used for sleepiness prevention system for vehicles operators which can greatly contribute to public transportation system safety.

  • The purpose of this study was to analyze self-regulation about changing heart rate and perceived arousal variation when actors start their performance. Object of this study were 5 actors who belong to the theater selected using the purposive sampling method. This study used a measuring instrument of heart rate to measure arousal status, used behavior observation paper to observe and record self-regulation behavior and executed personal consultation after ending performance. There was graph mad by variation transition which calculated average and standard deviation about variation of heart rate each time of performance. The results of this study were as follows. First, there were high variation of awake level that actor's heart rates were rising before starting performance and the most high level of arousal was from 20minutes to 5minutes before starting performance. Second, there were self-regulation behaviors appeared such as deep breathing, breath controling, self talking, talking with other actors, concentrating an script, going to toilet, smoking, checking closes before starting performance. Third, when performance start, actors used psychological self-regulational method such as relaxation, self concentration, confidence reinforcement, coping with state or accommodation for controling raised arousal status.

  • The relationship between central nervous system (CNS) and enuresis has not been sufficiently elucidated despite the presence of several circumstantial evidences. Contrary to common belief, polysomnographic sleep analysis revealed that the disturbance of arousal rather than deep sleep was responsible for enuresis. Subsequent studies confirmed depressed sympathetic tone and retarded brainstem reflex indicating abnormal arousal threshold in enuretics. In accordance with the bladder-brain dialogue, chronic stimulation of bladder may modify the brainstem function elevating arousal threshold. Epidemiological studies have suggested the association between enuresis and various psychosomatic disorders like attention deficit hyperactivity disorder (ADHD), which has shown the abnormal brainstem reflex similar to enuresis. Taken together, CNS is assumed to play a crucial role in the pathogenesis of enuresis. Psychological assessment is vital to understand the psychodynamic effect of enuresis. Studies have shown that the prevalence of psychological problems was higher in enuretic children and externalization of the symptoms was usually found. Several explanations have been brought up regarding the development of enuresis and psychological problems. Enuresis may cause psychological problems and vice versa. Otherwise, both may be associated with other variables, such as socioeconomic status (SES).
