Automated Real-time Classification of Functional States Based on Physiological Parameters
An automated real-time classification of human functional states is an important problem for stress resistance evaluation, supervision over operators of critical infrastructure, automated teaching and phobia therapy. In this paper we propose a novel method for binary classification of functional states based on the integrated analysis of (peripheral) physiological parameters: galvanic skin response, respiratory rate, electrocardiographic data, body temperature, electromyographic data, photoplethysmographic data, muscle contraction. The method is based on Gradient Boosted Trees algorithm. A testing of the method showed that in case of stress vs. calm wakefulness differentiation a reliability of the method exceeds 80%.

Objectives. Arterial blood pressure and serum blood glucose concentration, and the level of anxiety, as determined by the Spielberger test, as physical and psychological markers of stress under “modernization”, were studied in groups of native Siberians: the Khanty and the Mansi.
Results. The fraction of respondents with a high level of anxiety is 64% of the total sample. The average values of systolic and diastolic blood pressure are higher among natives living in large than in small “national” settlements (p<0.05). The arterial blood pressure of town dwellers is even higher. The same patterns are seen in the blood serum glucose concentrations in female samples. The average arterial blood pressure (in males and females) and the blood serum glucose concentration (in females) increases as people diverge from “traditional” lifestyles.
Conclusions. The results demonstrate that “modernization” and urbanization have a serious stressing influence on the aborigines of North Siberia.
The monograph is devoted to the assessment of population health indicators and comprehensive analysis of the factors influencing on the health of indigenous people of Russian North.
The article deals with the emotional burnout syndrome as a problem of personality psychology despite the tradition in Russian psychology to regard it as a result of continuous professional stress and professional deformation. Basing on the analysis of different approached to emotional burnout problem in Russian and foreign works it was concluded that they lack explanatory potential and there is a demand for investigating this syndrome in a broader paradigm. The author provides systemic methodological outlook of the problem and defines its theoretical status. Syndrome of emotional burnout is treated as violation of value-meaning personal regulation that hampers experiencing of higher order values and leads to dissolution of meanings in practical and professional activities. This approach proves promising for explanation of the specific nature of this syndrome as well as for elaboration of preventive measures.
syndrome of emotional burnout, stress, value-meaning sphere, Personality, dynamic system of meanings, spiritual organism
The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
