[DESCRIPTION AND PRESENTATION OF THE RESULTS OF ELECTROENCEPHALOGRAM PROCESSING USING AN INFORMATION MODEL].

The paper proposes to apply the informational modeling of correlation matrix developed by I.L. Myznikov in early 1990s in neurophysiological investigations, such as electroencephalogram recording and analysis, coherence description of signals from electrodes on the head surface.

Phenomenological description of local extremes on contrast sensitivity curves.

Previous studies have demonstrated that human contrast sensitivity curves have marked extremes [4]. This phenomenon has not yet been investigated. The present report describes studies of plots of frequency-contrast characteristics obtained using gratings with orientations of 0 degrees , 90 degrees , and 135 degrees .

[A phenomenological description of local extremums in contrast sensitivity function].

It was shown that human contrast sensitivity function (CSF) had noticeable extremums (Evseev et al, 1987). This phenomenon has not been closely investigated yet. In present paper, we studied human CSFs that were obtained by using gratings with 0 degrees, 90 degrees and 135 degrees orientations.

[Periods in the working cycle and morbidity of submarine personnel on long-term self-sufficient cruises].

The authors review literature dedicated to the attempts at defining periods within the working cycle of nuclear submarine personnel on long-term self-sufficing cruises, and propose own definition of periods. Characteristics of the epidemiological process in pressurized vehicles are described. The general morbidity is presented in values of an intensive index.

[The health of the command officer staff doing their service in Polar regions].

Initial referral (not considering dental diseases) for the last 4 years was analyzed in servicemen from the Northern Fleet, group of navy specialists serving in Headquarters was investigated. Anamnesis and central hemodynamic parameters were studied in casual sample (388 senior officers), special questionnaires were used to determine intensity of service activity. According to the data obtained during the last 4 years level of morbidity, hospitalization and disability (without dental diseases) in servicemen constituted 857.
