[Method of evaluating occupational suitability to precision work]. / Metod opredeleniia professional'noi prigodnosti k pretsizionnym vidam deiatel'nosti.

An original method concurrent with functional system of occupational activities assessed occupational ability to highly precise work (watch assembling). Female assemblers with noticeable ability to this work, if compared to those with the diminished ability, demonstrate better occupational achievements, better functional state, lower fatigue at work, however presenting no differences in ophthalmologic and psychophysiologic criteria. The authors designed and put into practice a method based on timing of notably delicate movements and on psychologic criteria of durability to monotonous work.

[Quantitative characteristics of the causes of functional overstrain of the hands]. / Izuchenie kolichestvennykh kharakteristik prichin funktsional'nogo perenapriazheniia ruk.

Functional studies of hands strain covered 2351 women who performed multiple manual maneuvers with absent, mild and moderate efforts. Considered reasons of the functional strain were: number of the maneuvers per shift, applied efforts, work intensity, length of service, previous work hardiness, hand efforts beyond the worktime, specific traits of workers (age, health state). Functional strain of hands was assessed by means of an Articular Pain Index which is general evaluation of severity, intensity and frequency of pain in hand joints. The authors suggest norms for allowable and hazardous quantity of hand maneuvers in accordance with their structure.

[Working conditions and functional body stress of operators in the television video recording centers]. / Usloviia truda i funktsiona'lnoe napriazhenie organizma operatorov videozapisi teletsentra.

In order to determine the ways for prevention of operators' overstrain, the working conditions and functional body stress were dynamically studied during the 12-hour shift by means of TV video-recording. The majority of operators experienced some neurologic disorders, high rates of situational and personality anxiety and an elevated level of neurotism. Mean rate of potential systoles was 75 +/- 2 per min, systolic arterial pressure 114 +/- 2, diastolic AP 74 +/- 2 mm of mercury column. No renewable dynamics of the above indicators was noted. The Kerdau vegetative index experienced a decline from + 6.0 +/- 2.5 to -6.5 +/- 3.0 arbitrary units during the shift. The regulatory system strain index in the half of the examined workers reached 300AU. The speed of data processing remained stable during the shift. To its end the critical fusion frequency on the peripheric visual field and remote visual thresholds decreased and differentiated achromatic thresholds increased. The level of operators' functional body strain could be regarded as admissible. The above characteristics of load response of some physiologic systems were assumed to be variants of an adaptable norm. The proposed preventive measures assisted in decreasing operators' functional body strain.
