Time-related changes in the speeded performance of complex cognitive tasks are considered to arise from the combined effects of practice and mental fatigue. Here we explored the differential contributions of practice and fatigue to performance changes in a self-paced speeded mental addition and comparison task of about 50 min duration, administered twice within one week's time. Performance measures included average response speed, accuracy, and response speed variability. The results revealed differential effects of prolonged work on different performance indices: Practice effects, being more pronounced in the first session, were reflected in an improvement of average response speed, whereas mental fatigue, occurring in both sessions, was reflected in an increase of response speed variability. This demonstrates that effects of mental fatigue on average speed of performance may be masked by practice effects but still be detectable in the variability of performance. Therefore, besides experimental factors such as the length and complexity of tasks, indices of response speed variability should be taken into consideration when interpreting different aspects of performance in self-paced speed tests.

The importance of professional health is actualized. The structural-logical scheme of the genesis of the conceptual-categorical apparatus of the study was constructed and its axiological and structural-functional analysis of “professional burnout” was carried out. Specifies the author’s interpretation of the definition of “professional burnout”; the structural and logical scheme of the process of professional burnout is developed.

The article is devoted to the development of criteria as to safety study load for the school-age children. The main methodological approach is to determine the influence of the factors of the educational process on the development of mental fatigue in children. In the 1092 school-age children we evaluated independent associations between educational load levels and the development of mental fatigue. It was established that the mental capacity and the mental fatigue are influenced by factors like the severity of subjects, the number of lessons per week, homework assignment time duration (the factors contributing is from 37,0 to 55,3 %; p < 0,05–0,01). The calculated risks of developing the severe mental fatigue that are influenced by too high level of the criterion indicators of the study load are 1,39–2,09 (p < 0,05–0,001). By developing predictive models was proven the school-age children proportions reduce with severe fatigue on 9 % with 5 lessons a day instead of 6–7. We developed specific hygienic recommendations for safe level of the quantitative and qualitative study load components, including homework assignment time duration which can be used to develop sanitary regulations for schools. The maximum permissible study load for the 1st grade students is 20 hours per week, the 2-nd – 21, the 3-rd – 22, the 4-th – 23, the 5-th – 27, the 6-th – 28, 7–9-th – 30, 10–11-th – 32. Homework assignment time duration is 1 hour for the 2–9-th grade students and 1,5 hours for the 10–11-th grade students. It is of current interest to review the content of the State Standard of Secondary Education in order to reduce the children’s perception of subjects as difficult, as well as to reduce the number of academic disciplines in the timetable up to 8 for junior students, 10–13 for middle and senior students. We developed and implemented an algorithm for calculating the mental fatigue assessment integral indicator for monitoring the school-age children’ organism functional condition. This will allow us to optimize the distribution of the study load during the school day and the week and improve the organization of the educational process in general, that will help preserve and strengthen school-age children’ health. The perspective of further research is to establish the optimal level of motor activity of students and the influence of lifestyle factors on the school-age children’ health.

Background Bus drivers are a special group of professional drivers who are at a very high risk of fatigue. The aim of the study was to examine whether the driver’s subjective assessment of fatigue allows for the determination of its level and identification of its causes. Material and Methods The study group comprised 45 randomly selected bus drivers (mean age – 43.7±7.9 years, period of employment as drivers – 14.7±8.6 years). Examinations were performed in all subjects four times – before and after work on the “easy” route (outside the city center, small traffic intensity) and before and after work on the “difficult” route (city center, heavy traffic). The fatigue test questionnaire, based on the list of symptoms of fatigue prepared by the Japan Research Committee of Fatigue, was used in the study. Results The rating of fatigue after the work was significantly higher than that before the work. The profile of fatigue after work was not influenced by the type of route, but the assessment of most symptoms of fatigue reached a higher level after the “difficult” routes and the differences were statistically significant for 7 symptoms. Only the ratings of leg fatigue, feeling of heaviness, and the necessity to squint eyes and gaze with effort reached the higher levels after driving the “easy” routes. It has been found that the level of fatigue was significantly correlated with the job characteristics (driving time, the length of the route, number of stops, etc.) and with the abundance of food ingested and type of beverage (coffee vs. others) drunk prior to driving. Conclusions The questionnaire used in our study to assess the subjective feeling of fatigue has proved to be a sensitive and useful tool for indicating the level and causes of fatigue. The relationship between the symptoms of fatigue and the characteristics of job and lifestyle shows that actions must be taken by both the employers and employees to prevent fatigue in bus drivers.

Wstęp Kierowcy autobusów miejskich są grupą zawodową, w której ryzyko wystąpienia zmęczenia jest szczególnie duże. Celem badania było sprawdzenie, czy subiektywna ocena kierowców dotycząca zmęczenia pozwala na określenie jego poziomu, uwarunkowań i przyczyn. Materiał i metody Badanie przeprowadzono w grupie losowo dobranych 45 kierowców autobusów (średni wiek – 43,7±7,9 lat, staż na stanowisku kierowcy – 14,7±8,6 lat), zatrudnionych w przedsiębiorstwie komunikacji miejskiej w dużej aglomeracji. U wszystkich badanie wykonano 4-krotnie – przed pracą i po pracy na trasie „łatwej” (poza centrum miasta, małe natężenie ruchu) oraz przed pracą i po pracy na trasie „trudnej” (centrum miasta, duże natężenie ruchu). Zastosowano „Kwestionariusz do badania zmęczenia” wzorowany na liście objawów zmęczenia przygotowanej przez Japan Research Committee of Fatigue. Wyniki Kierowcy ocenili, że ich zmęczenie po pracy było znacząco większe niż przed pracą. Rodzaj zmęczenia po pracy nie był zależny od rodzaju trasy, ale oceny większości symptomów zmęczenia były wyższe po trasach „trudnych” (dla 7 symptomów różnice były statystycznie istotne). Jedynie oceny zmęczenia nóg, uczucia ociężałości, mrużenia oczu i konieczności wytężania wzroku osiągały wyższy poziom po pracy na trasach „łatwych”. Stwierdzono, że poziom zmęczenia był istotnie skorelowany z cechami pracy (czas pracy, długość trasy, liczba przystanków itp.) oraz z obfitością posiłku i rodzajem spożywanego napoju (kawa vs inne) przed pracą. Wnioski Zastosowany „Kwestionariusz do badania zmęczenia” okazał się narzędziem czułym i przydatnym do oceny poziomu i przyczyn zmęczenia. Związek symptomów zmęczenia z cechami pracy i stylem życia wskazuje, że w zapobieganiu zmęczeniu kierowców autobusów niezbędne są działania zarówno pracodawcy, jak i pracowników. Med.

A phenomenon known well before the onset of modern society, registered as a medical term not until the second half of the 19th century, when physiologists and psychologists inquired into physical and mental exhaustion resulting from excessive work as well as that which had no work-related etiology. Such condition of the severe mental fatigue which entailed deficiency of nerve-force was defined by American neurologist George M. Beard as neurasthenia. Taking into account scientific studies of enervation, the article examines some late 19th-century literary treatments of exhaustion in Joris-Karl Huysmans’s Against Nature and Wilkie Collins’s The Woman in White to present them as peculiar, decontextualized cases of exhaustion for exhaustion’s sake.
