CHANGING SCHOOL-BASED ANXIETY DURING PHYSICAL EDUCATION, TAKING THE INDIVIDUAL TYPOLOGICAL APPROACH INTO ACCOUNT

Purpose of the study: The purpose of the study is to identify changes in school-based anxiety in children aged 12 – 13 during their physical education using a special Program for the individual typological approach implementation. Methodology: Two groups had been formed: reference and experimental (25 people each); three methods were used (Method for studying individual typological peculiarities of middle-school children by A. Belov, Method of Kondash's anxiety scale (1973), and Method of identifying general physical education of students); diagnostic testing of physical fitness was conducted (long jump from the spot; lifting the body in 30 sec. (press); push-up (girls); pulling up on the crossbar (boys); running 30 meters, shuttle running 3x10; bending forward from a sitting position). Main Findings: The results of the study have been statistically processed with Excel 2000 and STATISTICA 8.0, using the Student's t-test for dependent and independent samples. The M average has been found; the differences have been considered significant at p < 0.05. Applications of this study: The Program for the individual typological approach implementation has been compiled with an emphasis on reducing school-based anxiety in children aged 12 – 13; its features, objectives, indicators, criteria, content, and forms of implementation have been substantiated; a set of general physical exercises has been developed for each type of temperament, which includes the exercises for some groups of muscles of the upper shoulder girdle, back muscles, abdomen, and hips. Novelty/Originality of this study: The significant improvement in the physical fitness of students from the experimental group compared to the reference one identified during the term proves the efficiency of the implemented physical education program, taking into account the individual typological approach to the personality of adolescents with an emphasis on reducing their school-based anxiety. The results of the study have allowed formulating recommendations for improving the approaches to conducting physical education classes

Clinical case of community-aquaired pneumonia on the background of previously undiagnosed occupational pulmonary fibrosis. Is occupational history important?

Interstitial lung disease is a systemic concept, which is understood as a group of progressive diseases, characterized by non-infectious inflammation in the wall of the alveoli and interstitial lung tissue and may result in pulmonary fibrosis. The publication deals with the clinical case of community-acquired pneumonia on the background of previously undiagnosed occupational pulmonary fibrosis. The complaints, anamnesis, clinical and instrumental data have been analyzed, special attention is paid to the professional history, which indicates long-term contact with toxic substances and negative factors of the industrial process. The data of pathomorphological research are given. Timely prevention and screening of workers involved in heavy work and work with harmful or hazardous working conditions, even after the cessation of work in a production environment, may contribute to early detection of interstitial lung disease and contribute to a positive prognosis for acute respiratory diseases occurring on its background

Structural and functional indicators of the heart of patients with ischemic heart disease and type 2 diabetes mellitus. Rhythmoinotropic response isolated myocardium at different levels of glycated hemoglobin

BACKGROUND: Adequate glycemic control can significantly reduce the risk of developing cardiovascular events. However, until now, glycaemic targets in aged patients remain a subject of discussion, especially in the conditions of the combined development of Type 2 Diabetes Mellitus (T2DM) and ischemic heart disease (IHD).AIMS: To examine the structural and functional heart parameters in patients with IHD associated with T2DM and the rhythmoinotropic responses of their isolated myocardium depending on glycated hemoglobin level.MATERIALS AND METHODS: The study included 44 patients with a diagnosis of "chronic IHD associated with T2DM", of which 2 groups were formed. Patients with glycated hemoglobin level (HbA1c) <8% were included in the 1st group, and patients with HbA1c ≥8% were included in the 2nd group. The structural and functional heart parameters obtained with ultrasonography, and the rhythmoinotropic responses of myocardium in patients ex vivo were analyzed using the right atrial appendage fragments obtained during elective coronary artery bypass graft. The inotropic response of muscle strips at a basic stimulation frequency of 0,5 Hz to testing influences was assessed. An extrasystolic test and post-rest test were performed.RESULTS: It was found that extrasystolic contractions of isolated myocardial strips in patients of the 2nd group appeared at shorter extrasystolic intervals, which indicates a greater excitability of the myocardium in patients of this group. Postextrasystolic muscle contractions in patients of the 2nd group had significant potentiation. The amplitude of the muscle strips contractions in patients of both groups was potentiative after short rest periods. However, with an increase in the rest duration, potentiation of contractions was observed only in the group with a higher HbA1c level. According to the ultrasonography data, it was found that the values of the endsystolic and diastolic volumes, the interventricular septum thickness and the left ventricular (LV) myocardium mass were significantly lower in the patients of the 1st group compared with the corresponding indicators in the patients of the 2nd group. The early LV filling velocity (peak E) was significantly lower in the patients of the 1st group, which indicates a slower LV relaxation. At the same time, the rapid LV filling velocity did not have a significant intergroup difference, but this indicator exceeded the reference values in both groups.CONCLUSIONS: With a moderately increased glycemic level (9,2 [8,0; 10,3]%), the structural and functional heart parameters are preserved both at the level of the isolated myocardial tissue and at the level of the whole heart

Exposure of Nuclear Track Emulsion to a Mixed Beam of Relativistic 12^{12}N, 10^{10}C, and 7^7Be Nuclei

A nuclear track emulsion was exposed to a mixed beam of relativistic $^{12}$N, $^{10}$C, and $^7$Be nuclei having a momentum of 2 GeV/$c$ per nucleon. The beam was formed upon charge exchange processes involving $^{12}$C primary nuclei and their fragmentation. An analysis indicates that $^{10}$C nuclei are dominant in the beam and that $^{12}$N nuclei are present in it. The charge topology of relativistic fragments in the coherent dissociation of these nuclei is presented.Comment: ISSN 1063-7788, Pleiades Publishing, Ltd., 201

On the generalised Ritt problem as a computational problem

The Ritt problem asks if there is an algorithm that tells whether one prime differential ideal is contained in another one if both are given by their characteristic sets. We give several equivalent formulations of this problem. In particular, we show that it is equivalent to testing if a differential polynomial is a zero divisor modulo a radical differential ideal. The technique used in the proof of equivalence yields algorithms for computing a canonical decomposition of a radical differential ideal into prime components and a canonical generating set of a radical differential ideal. Both proposed representations of a radical differential ideal are independent of the given set of generators and can be made independent of the ranking.Comment: 9 page

Eczema: tactics of choice external therapy

The therapeutic effects of synthetic tannins are based on their binding action, as well as on their anti-pruritic, antimicrobial and anti-inflammatory effects. Materials and methods. A clinical study of Neotanin spray, Neotanin lotion (suspension) and Neotanin cream was carried out in 8 clinical centres during the period from June, 2017 to January, 2018. The study had an open and non-comparative character. The study included 68 patients of both sex es aged from 1 month to 80 years suffering from eczema dermatosis in the acute weeping phase, including cases with complications after secondary infections (including eczema elements localized on the face). Before the study, information on the clinical history, demographic data, co-morbidities, physical examination data of the patients was collected. The treatment regimen included 2 stages: 1) Neotanin in the spray or lotion (suspension) form 3–4 times per day during 1–5 days, up to the full drying of eczema elements; 2) Neotanin in the cream form 3 times per day, up to the disappearance of the clinical manifestations of skin dermatosis. The duration of the study ranged from 5 to 14 days: the study was completed when a patient had achieved remission. The criteria for assessing the drug efficacy were as follows: dynamics of subjective complaints, objective assessment of the patient's condition (the presence and severity of clinical symptoms), dynamics of the Dermatology Life Quality Index (DLQI). Results. Neotanin preparations showed a high efficacy in the acute and subacute stages of the inflammatory process as an antipruritic agent. Itching stopped within 5 minutes after the drug application, with the antipruritic effect lasting for an average of 3–4 hours. In 85 % of the patients, marked excoriations were absent on the 3rd day of treatment. Neotanin demonstrated a pronounced anti-inflammatory effect. In 92 % of the patients, the symptoms of erythema and edema were significantly reduced one week after the beginning of treatment, with the manifestations of inflammatory exudation being conclusively decreased. One week following the beginning of treatment, 100 % of the patients demonstrated no oozing lesions. The absence of serious undesirable effects in the patients during the study evidences to the good tolerability and safety of this drug
