Mathematical assessment of the functional constraint of the organism in schoolchildren in the process of training and passing a unified national testing

In Kazakhstan, the process of the passing of the final examinations in school and entrance examinations in Education College or University is incorporated into a unified national testing (UNT). In the process of the preparation and passing UNT in certain predisposed subjects (persons) the emotional stress can be transformed into a pathogenic factor, disrupting the normal physiological functions, leading eventually to the formation of a variety of psychosomatic illnesses. The article focuses on the mathematical assessment of the functional tension of the student’s organism in the throughout preparation period and passing the UNT. The investigations were performed in a boarding school for Gifted Children of “Daryn” in the city Karaganda before (25, 10 and 3 days) and after passing UNT. Somatometrical and physiological indices of the cardiovascular system and the central nervous system have been estimated. Statistical processing was carried out using Statistica 6.0 package and special statistical software. Results of the calculation of pair-wise correlation coefficients were used for the estimation of the proportion influence of the input factors of the arguments on the output parameters of the function (it is used significant correlation coefficients, by p < 0.05). The examination stress due to UNT was revealed to cause the high neuro-emotional stress of the organism of students. Boys react to the emotional stress more markedly than the girls. There are presented typological features of the organism influence the degree of the expression of the response. The UNT effectiveness is significantly affected by statical (age, environment, performance, morpho-functional indices, typological features of students, personal anxiety), and the dynamical (level of functional stress of the cardiovascular, central nervous system and psychoemotional activity during the preparation) indices.
