[Organization of a medical occupational rehabilitation system for locomotive team workers]. / Organizatsiia sistemy meditsinskoi professional'noi reabilitatsii rabotnikov lokomotivnykh brigad.

The paper deals with the setting up of a system for early diagnosis of premorbidity and for medical professional rehabilitation of locomotive teams. Non-drug preventive measures are shown to have a high rehabilitative effect.

[Problems in establishing special pensions for locomotive team workers]. / Problemy l'gotnogo pensionirovaniia rabotnikov lokomotivnykh brigad.

The paper deals with a physiological rationale for fixing pensions for locomotive-drivers within the ranges of age and length of service. The study is based on the fact that the nature and conditions of their work accelerate their ageing and decrease their working capacity.

[Methods of nondrug prevention of diminished work capacity and impaired health in railway workers]. / Metody nemedikamentoznoi profilaktiki snizheniia rabotosposobnosti i ukhudsheniia zdorov'ia zheleznodorozhnikov.

The paper deals with the physiological assessment of some biologically active food additives (BAFA). The authors formulate principles in selecting BAFA to prevent fatigability and premorbidity associated with safe railway traffic.

[The research achievements and prospects in the field of railroad medicine in providing traffic safety]. / Dostizheniia i perspektivy issledovanii v oblasti zheleznodorozhnoi meditsiny po obespecheniiu bezopasnosti dvizheniia.

Experience in ensuring safe traffic at the All-Russian Research Institute of Railway Hygiene is summarized. Various aspects of this line of activities, such as medicopsychological professional selection, medical examination of engine-drivers, training how to behave in emergency, etc., are considered. Some new medical problems in ensuring safe traffic are presented.

[The medical prophylactic problems of driving locomotives by an engineer without an assistant]. / Mediko-profilakticheskie problemy vozhdeniia lokomotivov mashinistom bez pomoshchnika.

The medically preventive aspects of driving safety for engine drivers without an assistant are considered in the paper. It shows it necessary to solve the problem of preventing the fatigue of the visual and acoustic analyzers in the drivers in the research setting and to optimize the control desk and the driver's whole cab.

[The terminology in assessing the recovery of human work capacity]. / O terminologii pri otsenke vosstanovlenii rabotosposobnosti cheloveka.

The paper deals with the scientific and practical expediency of using the unified terminology in the rehabilitation of working capacity in man. The term "recreation" is proposed to define the processes and phenomena associated with recovered functions and forces of the human body, which have been lost at work.

[Physiological bases for work and rest schedules during shift work in Arctic tundra]. / Fiziologicheskoe obosnovanie rezhimov truda i otdykha pri vakhtovom metode raboty v usloviiakh Zapoliarnoi tundry.

Conditions of Far North determine use of shifted work mode for construction of railways. The studies proved that low-distance shifted work is the most acceptable due to preserved health and work performance, lower rate of ageing. This mode maintains adaptation to the region's conditions, high level of work performance, saves the qualified workers.

[Role of mental work in man's tolerance to whole-body vibration]. / O roli umstvennoi raboty v ustoichivosti cheloveka k obshchei vibratsii.

Phasic changes of psychophysiological parameters developed in response to vibration of 10 Hz and acceleration of 1 m/s2 for 1 h. During the first phase some parameters decreased and others increased. Later all psychophysiological parameters significantly decreased. Circulation parameters tended to decline during exposure. The psychophysiological changes were less expressed in the test subjects normally involved in mental work. This suggests that mental workers have higher tolerance to vibration effects.

[Selection of the psychophysiological criterion for evaluating whole-body low-frequency vibration]. / O vybore psikhofiziologicheskogo kriteriia otsenki obshchei nizkochastotnoi vibratsii.

In response to whole-body vibration of 10 Hz and acceleration of 1 m/sec2 applied for 1 hour the psychophysiological status varies in two stages. At stage 1 physiological functions are disturbed (primary disorder) and at stage 2 they recover partially or completely (compensation and adaptation). The level of compensatory and adaptive reactions can be used as a tolerance criterion of the vibration effect with respect to its magnitude and duration. The primary reaction can be used as such a criterion when the functions under study are exposed to direct biomechanical effects of vibration.

[Functional dynamics of the pilots of heavy transport helicopters in the course of a flight shift]. / Dinamika funktsional'nogo sostoianiia pilotov tiazhelogo transportnogo vertoleta v techenie letnoi smeny.

Before and after flights about 300 crewmembers of heavy transport helicopters were examined, using psychophysiological and integral methods that yield professionally important information. During a flight shift the health state of helicopter pilots varies via three stages: habituation, initial decline and distinct lassitude, with the latter developing after 5 h flight load. In order to increase human reliability in the pilot-helicopter system, it is advisable to allow 4 h flight time during a flight shift onboard helicopters of the above type. In this case the pilot exposure to vibration effects will also be limited. The paper describes a maximally permissible spectrum of vibration velocity for a 4 h exposure.
