The activity approach as a part of a socializing process in adaptive sports activities

The study and development of the socialization process is a topical problem for science and practice nowadays. The authors present in the article the analysis results of the activity approach as a part of the socializing process in adaptive sports activities. The material is addressed to the factors of social upbringing and the implementation of the goals and objectives of socialization in adaptive sports activities. The paper also contains the study results of socialization of schoolchildren with limited abilities in adaptive sports activities. In addition, the possibilities of sports and the negative impact of sports models on the socialization of children with limited abilities have been analysed in this paper. An integrated model of adaptive-sports extracurricular activities for students with limited abilities, its organization technology has been presented. As a result of the study, it has been proved that adaptive sports activities as an area of self-expression, manifestation and formation of certain abilities, gifts and talent, is an important part of socialization of the student which helps prepare students with limited abilities for life

Применение кластерного анализа с элементами нечеткой логики для оценки окружающей обстановки группы робототехнических средств

Возникновение чрезвычайных ситуаций, которые угрожают жизни и здоровью людей, резко повышает требования к полноте и точности представления информации о текущей ситуации. Современные робототехнические средства оснащены датчиками, работающими на различных физических принципах. Это приводит к росту входной информации, поступающей в управляющую систему. С учетом ограниченной производительности бортовой вычислительной системы, а также высокой априорной неопределенности наземной обстановки робототехнические средства не могут быть эффективно использованы без объединения получаемой информации от группы робототехнических средств и создания единой картины наземной обстановки. Решить задачу отождествления вектор-признаков, относящихся к одному объекту, а также оценить эффективность полученных решений можно по известным формулам теории проверки статистических гипотез и теории вероятностей только при нормальном законе распределения с известными математическим ожиданием вектор-признака и корреляционной матрицей. Однако перечисленные условия на практике, как правило, не выполняются. Предложен новый метод решения задачи отождествления вектор-признаков, не опирающийся на статистический подход, и, следовательно, не требующий знание вида закона распределения и значений его параметров. Предлагаемый метод основан на идее сочетания кластерного анализа и нечеткой логики и отличается сравнительной простой по отношению к базовым методам многомерной непараметрической статистики. Обсуждаются математические аспекты метода нечеткой кластеризации и возможное упрощение алгоритма нечеткого отождествления при временных ограничениях. Установлено, что применение нечеткой кластеризации объектов в сложной наземной обстановке позволяет уменьшить количество ложных распознаваний объектов по сравнению с существующим статистическим подходом, ориентированным на использование нормального закона распределения. Показано преимущество предлагаемого метода отождествления вектор-признаков объектов, даны сравнительные значения по количеству ложных распознаваний. Даны рекомендации построения правил нечеткого вывода при создании базы знаний экспертной системы

Hypoglycemia and the risk of cognitive impairment and dementia in elderly and senile patients with type 2 diabetes

Research results show that poor glycemic control and recurrent episodes of severe hypoglycaemia are associated with a decrease in cognitive function in elderly people with type 2 diabetes mellitus (T2DM). On the other hand, patients with diabetes mellitus associated with cognitive impairment/dementia are most at risk of developing hypoglycaemic conditions. It is obvious that the relationship between hypoglycaemia and dementia is very complex and has a mutually aggravating nature. Studies also show that individuals of older age groups with diabetes and cognitive impairment have a high risk of developing hypoglycaemic conditions, such as unwanted side effects from glucose-lowering therapy. In this case, of particular interest is the question that is being actively studied at the present time, which is concerning the effect of different groups of glucose-lowering antidiabetic drugs on the cognitive status and the rate of cognitive decline in diabetic patients with cognitive impairment. In this review, we attempted to summarise, systematise, and present data available in the literature concerning the effect of hypoglycaemia on the risk of cognitive impairment and dementia in elderly and senile patients with type-2 diabetes, as well as the degree of participation in this process of of various groups of sugar-lowering antidiabetic drugs

Impact of delayed neutron constants on reactivity effects measured in a fast reactor

Delayed neutron parameters of fast VENUS-F reactor core configurations are determined with Monte Carlo calculations using various nuclear data libraries. Differences in the calculated effective delayed neutron fraction and the impact of the delayed neutron data (6- or 8-group precursors) that are applied in the experimental data analysis on the measured reactivity effects are studied. Considerable differences are found due to application of 235U and 238U delayed neutron data from JEFF, JENDL and ENDF evaluations

On the Reaction of Carbonyl Diphosphonic Acid with Hydroxylamine and O-alkylhydroxylamines: Unexpected Degradation of P-C-P Bridge

Derivatives of methylenediphosphonic acid possess wide spectra of biological activities and are used in enzymology as research tools as well as in practical medicine. Carbonyl diphosphonic acid is a promising starting building block for synthesis of functionally substituted methylenediphosphonates. Investigation of the interaction of carbonyl diphosphonic acid with hydroxylamine clearly demonstrates that it is impossible to isolate oxime within the pH range 2–12, while only cyanophosphonic and phosphoric acids are the products of the fast proceeding Beckmann-like fragmentation. In the case of O-alkylhydroxylamines, corresponding alcohols are found in the reaction mixtures in addition to cyanophosphonic and phosphoric acids. Therefore, two residues of phosphonic acid being attached to a carbonyl group provide new properties to this carbonyl group, making its oximes very unstable. This principally differs carbonyl diphosphonic acid from structurally related phosphonoglyoxalic acid and other α-ketophosphonates
