[Ways to study the work capacity of pilots in flight].

On the basis of a careful study of the Soviet and foreign literature, informativeness of physiological, biochemical, psychometric, biomechanical methods used to measure pilot performance inflight is evaluated. It is suggested that such performance can be assessed via a systemic approach and with the aid of the following parameters: functional state as indicated by physiological and biochemical recordings; subjective evaluations of the state using the psychometric scale; quality of the flight task performed; precision of piloting; and structure of controlling movements. This complex of parameters can be used only after landing. Inflight evaluation of pilot performance still remains an unresolved problem. The greatest promise holds search for objective criteria of automatic evaluation of the quality of pilot performance, structure of controlling movements, and physiological parameters on an integral time scale.

Ergonomics. Reducing mental and physical fatigue in the dental operatory.

The work output and the mental and physical fatigue generated by a dental procedure is affected by the length and type of operation, physical facilities, the amount of cooperation given by the patient, operating techniques, and the effective teamwork and rapport of the operatory dental team. Fatigue is also generated by stresses that arise outside of the office and which, when superimposed over the normal operating stresses of the office, can have a cumulative effect of decreasing output and increasing mental and physical fatigue for the dentist, the assistant, and the patient. Probably the three most important means to compensate for both routine and nonroutine physical and mental stresses of any type or origin are: (1) learn to cope with or resolve the origin of the stress; (2) develop a pattern of healthy living; (3) cultivate job satisfaction.

[Computer experience and further developments in the respiratory function laboratory (author's transl)].

Reported is on satisfactory results obtained with a small-size computer consisting of punching and scanning device, as well as plain writing machine in the respiratory function laboratory. Developed in on- as well as off-line processing by an own technical staff, a diagnostic and teaching program was established for all respiratory function routine methods with the advantages of a large number of cases examined, elimination of sources of error, considerable supply of data and information, automatic documentation and filing, plain writing, interpretation and evaluation of findings. In continuation of such works also the blood gas analysis has been included. These values as the total of disturbances of the pathophysiological acid-base status are considered and interpreted. Clinical correction is forced in this man-machine dialogue by automatic stops of the whole machinery before going on. Subsequently and in addition are computer alveolar-arterial oxygen pressure gradient, venous shunt and oxygen saturation and expressed utilizing the capacity of the small-size computer. Further developments in the respiratory function diagnostic- and teaching program for small-size computers--not too expensive in the building block principle - are intended.
