The article presents results of an empirical study of the relationship between school anxiety and motivation of learning activity at the stage of adaptation in students of 5th classes.The study involved 82 students of Bryansk state school aged 10—11 years, 46 boys and 36 girls.The techniques used in the study included Phillips' school anxiety test and M.R.Ginsburg’s technique for studying learning motivation.The obtained data was analysed using the methods of mathematical statistics (Mann-Whitney criterion and Pearson's criterion).As it was revealed, play motives of learning activity are associated with fear of not meeting the expectations of others and with low physiological resistance to stress.Positional motives are correlated with an individual’s fear of self-expression, of not meeting the expectations of others, with problems and fears in relationships with teachers, with the general level of school anxiety, with learning and social motives.The results of the study can be used by school counselor to reduce school anxiety and increase learning motivation of schoolchildren.

Forests are the most important regulator of greenhouse gas balances, being the depositor of most of the carbon in the world. At the same time, forests perform many other functions that are needed both in terms of preserving the integrity of the planet’s ecosystem and in the context of human development. Climate change has become a new global challenge, increasingly perceived by society as a whole and a certain part of the scientific and expert community as a source of undoubted danger to the population and material assets accumulated by mankind over the entire period of development. In this paper, we aim to review the studies conducted to date on the problem of ecological end economic modelling of the forestry considering both climatic and institutional factors of its development. The main outcome of our research is the concept of a future mathematical model of imitational type that will help to deeply understand the interactions between economy and ecology of the Russian forestry.

AimTo determine the course of food allergy in accordance with the level of respiratory tract injury in children of Eastern Siberia.Design of the researchWe have examined 70 children aged 2–16 , who have food sensibilization. We divided them into 2 groups: group I (n=32) with diseases of the upper and middle respiratory tract; and group II (n=38) with diseases of the lower respiratory tract.MethodsAllergological medical history, clinical laboratory examination and immunological examination, including the determination of IgA, IgM, IgG and IgE in blood serum. In cases where causal allergens were found, elimination diets were recommended.ResultsOnset of upper respiratory tract injury in group I was more often registered in children aged 0–1; in group II, it was in the 3–7 age group. Isolated food sensibilization was more often marked in group I as compared to group II. Atopic mechanisms of respiratory tract injuries were more often registered in group II children. In the course of the elimination diet, we marked positive dynamics in 100% of group I and in 75% of group IIConclusionThe most frequent allergens that cause respiratory forms of food allergy are hen eggs, cow milk, nutritive cereals, vegetables and fruit. Indices of a humoral link of immunity in the examined patients were more often registered as normal or their level is increased. Timely etiotropic therapy in the majority of cases allows for a stabilization of allergic inflammation.
