Age features of O2 mass transfer regimes in adolescents’ body at rest

The results of complex studies of the quantitative relationship between the stage-by-stage mass transfer of O2 and the efficiency of cardiorespiratory system functioning in relation to its consumption in adolescents’ body under conditions of relative rest are presented. The results obtained show that in adolescents, the modes of mass transfer of O2 in the body and the nature of the respiratory and circulatory systems functioning in relation to its consumption have a number of age-related differences compared with adult men. So, in adolescents, the external respiration system at rest functions less economically than in adults. Each liter of O2 consumed by adolescents is extracted from almost 3 liters more than in adults the amount of air ventilated per minute through the lungs. The volumetric indicators of blood circulation are also higher in adolescents, which may indicate the influence of neuro-humoral rearrangements in the body during the pubertal period. The coefficient of oxygen utilization by tissues from arterial blood in adolescents turned out to be significantly higher, which may characterize a higher tension of tissue metabolic processes.

Clinical and Neurological Symptoms in Acute Brain Stroke from Gender Dymorphism and Age Features

To date, CVD, in particular acute cerebrovascular accidents, have a clear tendency to increase. The existing domestic and especially foreign literature testifies to the established important medical and social problems of acute cerebral stroke in the society of humanity around the world. Stroke can develop at any age, but its frequency and prevalence increase with age. About 80% of strokes occur in people over 65, with age having a major impact on stroke outcomes.

THE FEATURES OF FORMATION SOMATIC PATHOLOGIES AT INFLUENCE OF LOCAL VIBRATION IN THE CONDITIONS OF METALLURGICAL MANUFACTURE

Relevance. Local vibration is a significant factor in the production environment of metallurgical production, which affects health and efficiency. The aim of the study is to identify the exposure, gender and age features of the formation of general somatic morbidity associated with the impact of local vibration in the production of titanium alloys. Scope and methods. The prevalence of general somatic pathology was compared in 2596 workers who have contact with local vibration, with varying degrees of harmfulness of working conditions, and non-exposed persons according to the results of periodic medical examination using the methodology of occupational risk analysis of the Research Institute of Occupational Medicine. academician N. F. Izmerov. Results. At comparison of prevalence of a somatic pathology at workers in contact to local vibration to not exhibited persons according to medical inspection, and at different degree of harm of working conditions, are revealed the raised risks of formation of diseases nervous, kostno-muscular, endocrine systems, respiratory organs, digestion, an ear, a skin, an arterial hypertensia, the mental frustration, the raised weight of a body, gynecologic diseases with a tendency of growth of the majority of them at the big levels of vibration, more often at small, less often - average degree of communication with working conditions. The frequency of pathology in exposed workers was higher in all age groups. Average degree of communication with working conditions of a gynecologic pathology at the age of 18-25 years was marked. At men frequency of a pathology of respiratory organs, digestion is revealed authentically big, than at women; an ear; skin at the big relative risks 1,2-1,3, of the raised arterial pressure and hyperglycemia. Conclusion. A higher frequency of visceral pathology of a number of body systems under the influence of local vibration of high levels may justify the need to develop differentiated preventive programs to minimize its negative impact, taking into account the identified features in sex and age groups.

Features of education of dignity in junior schoolchildren

The article is devoted to the topical problem of educating dignity in junior schoolchildren. Based on the analysis of philosophical psychological and pedagogical literature, generalization of the obtained empirical data, use of pedagogical diagnostics, the basic tendencies and features of education of dignity at younger schoolchildren are revealed, criteria (cognitive, emotional-value, active) are defined with the corresponding indicators, which allowed to characterize dignity in junior school students (high, medium, low). Students' understanding of the concept of "human dignity", the peculiarities of its upbringing and behavioral manifestations is considered. The practical significance of the study is determined by the fact that its results allow to improve the quality of the educational space of the school, to increase the effectiveness of its impact on the moral and ethical development of the younger generation, to adapt the activities of junior students to real life. The defined age features of students of grades 1-4 allow to provide a qualitatively new educational effect in solving the problems of moral education of schoolchildren, features of influence of pedagogical and educational systems on formation and development of the person are considered. Various approaches to determining the essence of moral value – dignity and factors of its successful formation, which have gained recognition in foreign pedagogical thought and spread in educational practice, are analyzed. The article reveals the state of formation of dignity in junior schoolchildren at the ascertaining stage of scientific research. The practical significance of the article is that its materials can be used in the organization of educational work of general education institutions and training of primary school teachers
