[Calculation of the number of personnel required for technical servicing of medical equipment]. / O raschete chislennosti personala dlia tekhnicheskogo obsluzhivaniia meditsinskoi apparatury.

The determination of the total number of personnel for servicing medical technology in terms of the conditional units of the complexity suffers from disadvantages and does not assure that the personnel is adequate in number to provide the specified efficiency when performing the preset tasks by medical technology. Free from these disadvantages is the proposed method. In this case, the total number of personnel is derived in terms of the queuing theory by applying the Kolmogorov-Chepman equation and the commonly known Erlang problem. By using the iteration method and the derived relationships the total number of personnel may be computed thus providing the predetermined possibility that medical technology should perform the preset tasks.

[Dynamic medical control over the members of the flight crews in the process of long flights]. / O dinamicheskom meditsinskom kontrole za chlenami letnykh ékipazhei v protsesse dlitel'nykh poletov.

On the basis of the study of cardiovascular, respiratory, nervous and motor systems of crewmembers (60 people) who made prolonged aircraft flights (over 10 hours) two types of physiological reactions have been defined. One type includes emotional reactions to short-term complications in the flight, and the other involves fatigue and relative exhaustion of the functional systems as a result of strenuous work and adverse flight effects. It has been demonstrated that the dynamic medical control is an important addition to the preflight and interflight physical examinations of the flying personnel.
