Spektrofotometric research of indicators of an oxidizing stress allows to predict individual hypoxic resistance. The oxidizing modification of proteins and level of reduced thiols as an indicator of an oxidizing stress were investigated. The resting levels of indicators of spontaneous oxidizing modification of proteins at the low hypoxic resistance group are much lower, than that at the high resistance group. The resting levels of reduced thiols in the high resistance group were lower than that in low resistance group.

Keywords: spectrophotometry, hypoxia, oxidizing modification of proteins, reduced thiols.

Savchenko V. V., Suzdaltsev D. A., Korolev V. A.. Komrakov D. Yu. Comparative analysis of contact and noncontact technologies for human physiological state monitoring

This article focuses on analyzing current physiological data monitoring systems. Applicability of physiological signals registration methods to monitor responses both in lab and in natural daily life conditions is demonstrated. The method of analyzing correlations of physiological responses while being exposed to emotionally relevant information is suggested. The significant correlation is found between alternations in physiological signals, recorded with contact and non-contact method. Application of non-contact physiological signal registration method is argued to be an alternative to conventional means of human functional state monitoring.

The study aimed to identify the decision-making mechanisms of the human brain for operators in complex technological environments. Design of experiments includes modeling of the real situations, digital image processing to develop and produce test images. To study the main patterns of brain activity we used the method of functional magnetic resonance imaging (fMRI). An assessment of the dynamics of blood flow in the context of an active task was compared to one in passive condition. We establish the opponent principle for interaction of the brain areas responsible for decision-making. Results of the study are considered from the standpoint of the theory of temporal binding of the individual images into a Gestalt. Our work demonstrates possibility of objective measurements by fMRI the functional state of human (operators) brain in technological environment.

Lomov О. P., Kudryavtsev V. M. Methodological bases for the creation of information-analitical system for integrated assessment of public health and the risk of deterioration

Developed a methodical approach to comprehensive assessment of public health, intended to solve the problems of automation of information-analytical work of specialists, experts, analysts and managers of state authorities of the Russian Federation involved in the analysis of national security issues at the macro level (the subject of the federation and the federal district, the country overall).

It has been shown that when calculating the summarized population's health index and the significance (weight) of partial signs, it is expedient to use the calculation from the potential death risk index rather than an expert judgment. The results of calculation examples using morbidity rates suggest that public health can be assessed on this methodic ground.

It is advisable to apply the proposed method for assessing the population's health during sanitary-and-epidemiological surveillance (socio-hygienic monitoring) when decisions are taken on the lines of heath-promotion measures to reduce morbidity mainly by circulatory diseases neoplasms, injures and intoxications.

Keywords: public health, morbidity, mortality, methodology.
