[Physiologic and hygienic evaluation of the job and health status in workers of shoe factory]. / Fiziologo-gigienicheskaia otsenka truda i sostoianie zdorovía rabotaiushchikh v osnovnykh tsekhakh obuvnogo proizvodstva.

The article contains materials on complex physiologic and hygienic evaluation of work performed by various shoe-making occupations. The main occupational hazards are air pollution with chemicals, noise, vibration, considerable physical and psychophysiologic strain, visual exertion, inadequate working posture. The workers demonstrated fatigue of the main body functions during the shift. Diseases of locomotion and nervous system appeared to be prevalent among the shoe-makers. The complex of prophylactic measures is elaborated.

[Functional state and development of diseases of the locomotor system in seamstresses in relation to their work characteristics and degree of physical exertion of the hand muscles]. / Funktsional'noe sostoianie i razvitie zabolevanii oporno- dvigatel'nogo apparata u shvei v zavisimosti ot osobennostei ikh truda i velichiny fizicheskoi nagruzki na myshtsy ruk.

Physiological and clinical on-the-spot studies were performed of the labour conditions in 3 groups of female sewing-machine operators (respectively, engaged in making women's dresses, men's suits and men's coats). The analysis performed revealed different degrees of physical load and fatigue in the operators depending on the occupational peculiarities. Specific features of the peripheral nervous system and locomotor system disorders were studied in details, along with the causal relationships underlying the degree of physical load and fatiguability, overstrain development and cumulation. The results of the study were used as a basis for setting Health-Related regulations for sewing-machine operators.

[Significance of the degree of static tension in the development of fatigue and overstrain of the neuromuscular system in polishers employed in the glass industry]. / Znachenie velichii staticheskikh nagruzok v razvitii utomleniia i perenapriazheniia nervno-myshechnogo apparata shlifovshchits stekloizdelii.

The research data proposed proved the key role of the muscles' static tension in the process of fatiguability and strain growth in glass-work polishers' neuromuscular mechanisms. It was proved that a comparatively greater static load on the shoulder girdle muscles in glass-work polishers, as compared to crystal-polishers, results in more vivid pathologic changes in this professional group. The research served as a basis for a set of health-related measures, including both palliative and radical approaches.

[Improving working conditions of female glass cutters (polishers)]. / Ozdorovlenie uslovii truda grani'lshchits (shlifovshchits) khrustala.

The analysis of modern vast data on working conditions and health status of female workers involved in glass product processing is presented. The results of the authors' study at one of crystal plants are also given. Due to the above analysis major occupational factors noxious to workers' health have been identified. Some shortcomings of the health-improving measures proposed by a number of researchers have been underlined, among them there are insufficient physiologic standardization of work activity and the absence of complex decisions on workplace ergonomization including design of machine tools and work furniture, dust localization and suction, elimination of constant hand cooling by water.

[Complex assessment of working conditions of painters in industrial plants and their improvement]. / Kompleksnaia otsenka truda maliarov promyshlennykh izdelii i ego optimizatsiia.

The working conditions of the female workers engaged in industrial painting do not correspond to the optimal criteria and exceeds the permissible levels in some respects. Considerable muscle loads which cause the workers' fatigue and corporal pain lead to the overstain of the locomotor system. A complex of health improving measures is proposed to create more favorable labour conditions, lower fatiguability and promote prevention of locomotor system disorders.

[Mechanism of the discontinuance of work as a consequence of fatigue according to the change in the electromyogram in a hypnotic state]. / K voprosu o mekhanizme prekrashcheniia raboty vsledstvie utomleniia po dannym izmeneniia élektromiogrammy v gipnoticheskom sostoianii

A study was made of the changes in the bioelectrical activity of the muscles in the course of local static work up to "refusal" under the usual conditions and under condition of inhibition of the program-control function of the cortex (during the somnambulistic stage of hypnosis). Experimental results indicated that during the hypnotic state the time of persistence of the static effort doubled in comparison with control; the bioelectrical activity increased 1 1/2-2 times, and in individual experiments--3--4 times. In the light of the data obtained the mechanism of formation of "refusal" to work could be viewed as an active arrest of the activity of the central formations realizing the program-control functions.
