PREDICTION OF THE DEVELOPMENT OF PERIODONTAL DISEASE

Introduction. Periodontal tissue disease is one of the most common dental pathologies, which among young people occurs with a frequency of 60% to 99%. Therefore, the problem of finding new links in the pathogenesis, the reasons for the growing prevalence of periodontal disease, as well as effective methods for its early diagnosis and prevention, is relevant. Objectives. Establish the possibility of using individual stomatological and psychophysiological features to predict the development of periodontal disease. Materials and methods. 156 students aged 18-23 years old without systemic diseases were surveyed for some features of oral hygiene and nutrition. Also the study subjects underwent a dental examination, psychological testing and the assessment of individual typological features of higher nervous activity and autonomous regulation. The model for statistical prediction were designed using neural networks. Results. Two neural networks were designed with the best predictors among dental history and examination, psychological testing, parameters of higher nervous activity and heart rate variability analysis. The diagnostic sensitivity of the first prognostic model was 83.33 % and the specificity was 92.31 %. The second model was characterized by 90.00 % sensitivity and 78.57 % specificity. Conclusion. The method of modeling using neural networks based on the index assessment of the condition of teeth hard tissues, the level of oral hygiene and the evaluation of psychophysiological features can effectively predict the risk of periodontal disease development in young people

Influence of the type of higher nervous activity on milk yield and the productive longevity of mares

The presented work is the result of studies of the influence of the type of higher nervous activity on the dairy productivity of mares of the Russian heavy draft horse breed on stationary koumiss farms. To determine the types of higher nervous activity, a motor-food technique developed by the All-Russian Research Institute of Horse Breeding was used. The milk yield was counted at animals for the first lactation, for the highest lactation, on average for one lactation and a lifelong milk yield of mares. The milk yield on average for lactation is almost the same in mares with a strong balanced mobile type and with a strong unbalanced type of higher nervous activity. Animals of a weak type and a strong balanced inert type of higher nervous activity lag behind them in this indicator by 11-13%. Horses with a strong balanced mobile type, a strong unbalanced type and a weak type of higher nervous activity are most suitable for the duration of economic use and lifelong milk production. The mares with a strong balanced inert type of higher nervous activity are the least productive in terms of duration of economic use and lifelong milk yield on koumiss farms.

To the study of higher nervous activity in schizophrenia in children

The current state of the theory of conditioned reflexes dictates the necessity of introducing a physiological method for studying higher "nervous activity" into the everyday life of clinical research.

On the symptomatology of tumors of the frontal lobes

Despite the numerous experimental, embryological, phylogenetic, and anatomical and clinical data, the question of the significance of the frontal lobes in human higher nervous activity is still far from its final solution. The extensive literature on the subject under discussion provides valuable material for clarifying the problem of the functions and syndromes of the frontal lobes.

General Theory of Intelligence

In this paper, the dependence of the properties of the brain, its structure, functions and the higher nervous activity derived from them on the physical properties of the universe is analyzed.

PECULIARITIES OF MOTIVATION OF YOUNG ATHLETES TO VARIETIES OF SPORTS TOURISM

The article considers the peculiarities of motivation of young tourists to engage in a variety of sports tourism. The low level of physical activity of youth stipulates the search for forms of involvement of children in various types of physical culture and sports. Teachers’ motives for classes have a significant impact on the improvement of physical culture and sports work and increase its effectiveness. Based on the analysis of the scientific literature, it is defined that sports tourism develops in two interrelated but independent areas: the sports trips and the competitions in tourism. Sports trips are carried out in accordance with regulations. As most researchers note, such activities have a great potential in the upbringing and development of children. Competitions in sports tourism involve a unified comparison of skills and abilities to overcome natural (or artificial) obstacles passing distances of a certain complexity. It has recently been observed that young tourists, under the guidance of a teacher, specialize in a particular area of sports tourism, that in its turn means preparation and participation in competitions in tourism, or just prepare and take sports trips. The purpose of the article: to identify the characteristics of motivation of young tourists to engage in a variety of sports tourism. Based on the analysis of the scientific literature, it is defined that the motivation to engage in various types of sports tourism depends on age, gender, type of higher nervous activity, experience of sports tourism. Children often prefer motives: enjoyment of activities, pleasant pastime, gaining of new knowledge, skills and abilities, development of physical qualities and also strengthening of health. Using the method of questionnaires, it is defined that the priorities of the motives of young tourists depend on the direction of sports tourism. The data confirmed the conclusions of scientists on the priority of motives, but young tourists, whose main activity is going camping, hiking, taking sport trips prefer the motive of aesthetic pleasure and thrills, whereas participants of sports competitions in tourism highlight the motive of physical perfection. In addition, the motives for communication, cognition, gaining of useful skills and knowledge are essential for the campers, while the participants of the competitions are in need of approval and increasing prestige of individual. In order to form a harmonious personality, the leaders of tourist clubs need to use different directions of sports tourism organizing classes.Key words: camping, hiking, competitions in sports tourism, young athletes of tourism, motive for classes.

Influence of typological features of higher nervous activity on the specifics of developing a dynamic stereotype in the process of correcting sound pronunciation in preschool children

In the process of forming sound skills, it is necessary to take into account not only the methodological and theoretical requirements for the implementation of speech therapy work, but also the psychophysiological patterns of the organization of higher nervous activity, which allowsyou to competently build a didactic trajectory of work with a child, predict the pedagogical result, increase the efficiency of mastering motor dynamic stereotypes in the process of automating the set sounds.
