Gordieiev A. Methods and biotechnical system for professional recruiting of extreme activities operators'

The object of research is the procedure for assessing the psychophysiological state of the extreme activity operators' body. The goal of the work is to increase the efficiency of the procedure for professional recruiting of the extreme activity operators' by developing and improving methods and models for quantifying the psychophysiological state of the operators' body, as well as creating a modern biotechnical system. Methods of research: mathematical statistics; designing software products based on the UML language; functional modeling of IDEF0; processing the power spectral density of the EEG signals; Monte Carlo simulation; robust processing of statistical data; algebra of logic of sets; experimental research. Theoretical results: the functional model of step-by-step research of the extreme activity operators' body for professional recruiting has been improved. Further development was obtained by the method of determining the integral level of psychological professional suitability of extreme activity operators' by computerizing psychological testing procedures taking into account their anthropometric and adaptive capabilities. For the first time a method for assessing the psychophysiological state of the extreme activity operators' body was developed based on the parameters of the spectral power density of the background and transient biosignals of the cerebral cortex. For the first time a three-dimensional mathematical model for the correlation of the extreme activity operators' body was developed. Practical results are as follows: the procedure for classifying of extreme activities operators' by temperament type has been computerized; developed platform-independent software with a graphical interface and decision support system for a medical specialist based on the MatLab software environment; developed a relational database based on MySQL for storing experimental data of the biotechnical system; a biotechnical system has been developed that includes subsystems for collecting, storing, processing data and supporting decision-making. Degree of implementation - the results of the thesis are implemented in the National Antarctic Research Center; in the State Institution "National Institute of Surgery and Transplantology. A.A. Shalimov" of Ukraine; in the educational process in the National Aviation University at the Department of Biocybernetics and Aerospace Medicine. The domain (field) of application - medicine.
