[Military ecology and military hygiene: the concept of an interaction].

At the modern level of society development, on the one hand its Armed Forces are the object that requires the defense from unfavourable effect of environmental factors, on the other hand they are potential source of ecology worsening. The problem of ensuring ecological safety in the army and navy becomes urgent. In order to solve this problem first of all it is necessary to develop the conceptual bases of military ecology.

[A method of assessing actual nutrition of organized collectives based on mathematical modelling].

Subjects completely adapted to a complex of factors of their working and natural environment, besides a stable emotional sphere and physical working capacity, develop a certain stereotype of food consumption, that objectively determines relatively constant levels of this or that component in the ration they receive. The authors have developed a method of mathematical modelling of the expected consumption of food substances basing on the calculation of the ration chemical composition according to the menu, and on the further comparing with the level of actual nutrient consumption. A step-by-step regression analysis has enabled the authors to detect significant (by F-criterion) groups of daily ration food products for actual nutrient consumption, and to present the regression models for calculation the expected consumption of mineral substances in daily rations with the use of regression equation.
