In order to evaluate autonomic nervous system changes occurring before nocturnal headache attacks, we studied three subjects (one male, two females) suffering from chronic migraine. All three patients underwent a nocturnal polygraphic recording including continuous monitoring of systemic arterial pressure and heart rate. Two subjects showed increases and irregularities of arterial pressure before awakening with headache. These changes began during N–REM sleep and lasted during REM sleep preceding the awakening with headache. Heart rate did not change before the attacks. These findings do not support the hypothesis that autonomic instability during REM sleep represents the precipitating factor of the attacks. On a étudié avec des méthodes polygrafiques trois sujets (1 homme et deux femmes) souffrant d'hémicranie chronique avec des crises nocturnes. Chez deux malades les crises étaient précédées d'augmentation et d'irrégularité de la tension artérielle. Ces modifications commençaient pendant le sommeil N-REM et contineaient pendant le sommeil REM qui précédait le réveil avec hémicranie. La fréquence cardiaque n'a pas subi de modification avant les crises. Les résultats obtenus ne confirment l'hypothèse selon laquelle le facteur causant les crises est l'instabilité anticronique à la fase REM. Sono stati studiati con metodiche poligrafiche 3 soggetti (1 maschio e 2 femmine) affetti da emicrania cronica con attacchi notturni. In 2 di essi gli attacchi erano preceduti da incrementi ed irregolarità della pressione arteriosa. Tali modificazioni iniziavano durante il sonno N-REM e perduravano nel corso del sonno REM che precedeva il risveglio con cefalea. La frequenza cardiaca non si modificava prima dell'attacco. I risultati ottenuti non confermano l'ipotesi che il fattore precipitante gli attacchi emicranici sia l'instabilità anticronica della fase REM.

Occupational hygiene requires evaluation of different risk sources in the workplace. The level of physical workload may create stress, fatigue and injuries. Therefore, activity monitoring provides valuable information for companies in assessing and solving possible hazards in the workplace. The article presents a system using wearable technology to monitor and evaluate physical workload with in situ measurements. The system uses a smartwatch and a mobile application for Android phones. During workload monitoring, the application displays physiologic variables such as heart rate, calories, body temperature, galvanic skin response and number of steps. Additionally, the system computes absolute and relative cardiac cost, and Frimat coefficients. Tests were performed on 10 individuals from a janitor staff (5 men and 5 women), monitoring every task during their most demanding hour. Results agree with the type of activity developed in different intervals, showing light and very light workload for different tasks in all workers.

                PT. SPU Palembang is an industrial company that produces Hospital Furniture and Rehabilitation products with the trademark SHIMA. This study aims to reduce the physical and mental workload received by workers in the Machine Shop Department. This research is focused on the production process .Measurement of physical workload uses the calculation of the worker's heart rate by calculating the percentage of Cardiovascular Load (CVL). Measurement of mental workload using the National Aeronautics and Space Administration Task Load Index (NASA-TLX) score calculation method. The results obtained based on the aspect of NASA-TLX before the proposal almost all workers receive a mental workload with a value of > 80 that is included in the category of heavy mental workloads except Milling-Drilling Workers (4) have a score < 80 in the category of moderate mental workload. After the proposal all workers have a score < 80 so that the mental workload received falls into the medium category. Based on the proposals applied to the Lathe Worker (1) and the Milling-Drilling Worker (4) namely the improvement of work methods in the process of turning, punching, and the proposed holding of a reminder as a tool to remember, the results obtained %CVL from both workers < 30%. Three other workers, although experiencing a decline, remained at > 30%. The category of mental workload received by workers from previously included in the category of heavy mental workload dropped to moderate

AbstractThis study presents a comparative account of psychophysiological responses to music listening in healthy males and females. The stimulus material was a slow-paced taped rāga Desi-Todi on a flute. The participants listened to music for 30 minutes a day, for 20 days. Pre- and post-treatment procedure was adopted for assessments on psychophysiological measures. The study supports the following conclusions: (1) music listening produced significant decreases in the blood pressure (both systolic and diastolic) and heart rate of females, but had no significant effect in males; (2) music listening reduced stress, anxiety and depression, enhanced life satisfaction, optimism and hope, and was perceived as making life more meaningful in males and females; (3) the effects of music listening, that is, reduction in negative affect, enhancement of positive affect (except the ‘hope’ scores), and decrease in blood pressure and heart rate, were more intense in females than males.Keywords: music listening, gender differences, psychophysiological responses, negative affect, positive affect, blood pressure, heart rateFrenchDifférences en fonction du sexe des réactions psycho- physiologiques à l’écoute musicaleCette études présente un compte-rendu comparatif des réactions psycho- physiologiques à l’écoute musicale par des hommes et des femmes sains. Le matériel sonore de stimulation était l’enregistement d’un motif lent joué à la flute dans le style Raga (Desi-Todi). Les participants ont écouté cette musique à raison de 30 mn par jour pendant 20 jours. Une procédure a été adoptée pour évaluer les mesures psycho-physiologiques en pré et post-traitement. L’étude soutient les conclusions suivantes : (1) l’écoute musicale a produit une baisse significative de la pression artérielle (diastolique et systolique) et de la fréquence cardiaque chez les femmes, mais n’a pas eu d’effet significatif chez les hommes; (2) l’écoute musicale a réduit le stress, l’anxiété et la dépression, amélioré le sentiment de satisfaction, d’optimisme et d’espérance, et a été perçue comme rendant la vie plus riche de sens chez l’homme et la femme; (3) les effets de l’écoute musicale, c’est-à-dire la réduction des effects négatifs, l’amélioration des effets positifs (à l’exception des résultats concernant l’espérance), et la diminution de la pression sanguine et de la fréquence cardiaque étaient plus intenses chez les femmes que chez les hommes.Mots clés :écoute musicale, différence sexuelle, réactions psycho-physiologiques, effet négatif, effet positif, pression artérielle, fréquence cardiaque
