Morphological profile of the ovaries of high-yielding cows on day 0 of the induced sexual cycle

An important part of reproduction management programmes on dairy farms is the detection of infertile cows and early re-insemination to achieve higher rates of pregnancy. The purpose of the study was to investigate the features of gonadal morphogenesis in high-yielding cows in the conditions of industrial keeping technology on day 0 of the sexual cycle in vivo in real time. Structural, comparative, and statistical methods were used, as well as biotechnical methods of palpation cyclic examination of ovaries with differential diagnosis of morphophysiological or pathomorphological indicators. The results of diagnostics of the ovaries of dairy cows (n=128) on day 0 of the induced cycle detected by step activity sensors showed a significant structural polymorphism of these organs of the reproductive system. It was found: from 66.67% to 30.77% of cows with a physiological course of the follicular phase of the cycle, i.e., on day 0, a preovulatory follicle or the beginning of ovulation on the ovaries (subject to a decrease in the number of cows suitable for insemination with increasing lactation duration from 50-75 days to 211-306 days (P<0.001). Hypogonadism was diagnosed in 19.45% of cows, and in 61.11% – ovarian dysfunctions with the manifestation of cystic follicular degeneration; 19.44% of cows at the time of the study had irreversible chronic adhesive processes of the genital tract tissues in the “ovary+oviduct” area (ovophoritis and ovosalpingitis in latent form), which allowed for pregnancy to occur, with a pronounced tendency to increase this gonadopathy with an increase in lactation (respectively: 50-75 days – 0.00%; 76-160 days – 22.22%; 161-210 days – 22.22%; 211 and more – 33.33%; p<0.05). The trend of influence of subclinical disorders in the metabolism of cows of the experimental herd on the indicators of the biochemical composition of blood serum and the symptom of ovarian dysfunctions was investigated. Thus, the in vivo morphological and pathological profile of the ovaries of high-yielding cows on day 0 of the sexual cycle was established, which allowed optimising the artificial insemination regime and reduce economically nonprofitless sperm consumption. The results can be used in the practical work of veterinary medicine doctors, researchers, and applicants for higher education in veterinary and biological science

Morphological and molecular genetic diagnosis of CADASIL: a rare clinical case

Background: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary autosomal dominant vascular injury of the brain. Currently, the clinical diagnosis of CADASIL is based on the following criteria: the onset of the condition at a relatively young age (4050 years), recurrent lacunar infarcts, gradual progression of encephalopathy with the development of pseudobulbar syndrome and dementia, various emotional disorders, and autosomal dominant inheritance. Having a family history of relatives with similar symptoms. The diagnosis is verified on the basis of the results of the following studies: neuroimaging, instrumental, morphological, and laboratory. The presence of leukoaraiosis and multiple small bilateral infarctions in such anatomical structures as the basal ganglia and white matter of the cerebral hemispheres, visual tubercles and the pons, and brain stem during MRI diagnostics. Histologically, transmission electron microscopy reveals granular osmiophilic inclusions in the adventitial membrane of the blood vessels of the brain, and on the periphery in the adventitia of the vessels of skeletal muscles and somatic nerves and in vascular biopsies of skin flaps. A mutation in the Notch3 gene determines the clinic of the disease and morphological changes in blood vessels and is detected by a molecular genetic method. The article presents a clinical case, which was a manifestation of this rare hereditary microangiopathy. Clinical case description: A 43-year-old patient was admitted to the Department of Neurology of the Republican Clinical Hospital in Simferopol for ischemic stroke in the basin of the left middle cerebral artery. According to the anamnesis, the patient suffered from migraine without aura from a young age and lacunar strokes; examination revealed a decrease in cognitive function, and MRI showed signs of microangiopathy of cerebral vessels. For final diagnosis, the patient underwent an intravital pathomorphological examination of the biopsy of the musculoskeletal flap; the results obtained made it possible to make a reliable diagnosis of CADASIL. Conclusion: Understanding and knowledge of such a rare pathology as CADASIL is crucial for the rapid recognition of a characteristic clinical picture for further appointment and interpretation of the results of morphological and molecular genetic diagnostics, making it possible to make the correct diagnosis and treatment.

The analysis of problems of supporting long-term nursing of individuals who lost their ability to self-care in Russia

The article presents results of research study intended for identifying degree of cognitive impairment in elderly citizen residing in conditions of institution of stationary social support. The study was conducted in a multidisciplinary rehabilitation institution of social services. The obtained results confirmed necessity to organize primary preventive work and permitted to test program of correctional classes with elderly people having cognitive impairments. The comparative analysis of results of primary and control diagnostics testifies that efficiency of corrective impact depends on degree of cognitive impairment and beginning time of correctional work. The early correction of cognitive abnormality of light and moderate degree is the most successful. It actualizes issues of timely diagnosis of cognitive abnormalities in elderly people and necessity to develop activities of primary prevention of dementia.

Concentration of Fluorine Atoms and Kinetics of Reactive-Ion Etching of Silicon in CF4 + O2, CHF3 + O2, and C4F8 + O2 Mixtures

A comparative study of the electrophysical parameters of the plasma, the fluorine atom concentra-tions, and the kinetics of reactive-ion etching of silicon in CF4 + O2, CHF3 + O2, and C4F8 + O2 mixtures of a variable (0–75% O2) initial composition is carried out. It is shown that the dominant etching mecha-nism is always the ion-stimulated chemical reaction Si + xF → SiFx, whose rate has a maximum in the region of 20–50% O2. Based on the results of plasma diagnostics, it is found that the similar behavior of the concen-tration of fluorine atoms is typical only for mixtures of CF4 + O2 and CHF3 + O2, while in the C4F8 + O2 mix-ture, there is a nonmonotonic change in the probability of the interaction. It is assumed that the latter effect is caused by the competition between the processes of reducing the thickness of the fluorocarbon polymer film and the oxidation of the silicon surface by oxygen atoms.

Iron deficiency conditions prediction and prevention in children

The relevance of iron deficiency issues is due to the high frequency and tendency to steady growth, affecting the quality of life of the population. Pregnant, lactating women and young children are at high risk of developing iron deficiency conditions. Among pregnant women, a direct correlation was found between iron deficiency in the early stages of gestation and the pathological course of pregnancy and childbirth, lower indicators of physical, psychomotor development of children. Materials and methods. A prospective cohort study of 248 mother-child pairs was conducted. Pregnant, lactating women: the main group-women who received iron preparations during registration-106 persons, the comparison group-those who did not receive iron preparations-142. Inclusion criteria: absence of exacerbation of chronic pathology, allergic reactions, gastrointestinal pathology, infectious diseases. The women were examined at the end of the 3rd trimester and the postpartum period. Catamnestic observation was carried out for 248 children born to pregnant women. All children were observed with the informed consent of their parents. The duration of observation was up to a year. The children of the main group (106) and the comparison group (142) were singled out. Children of the main group on natural feeding (98) were divided into two subgroups. The first subgroup - 47 children whose mothers received iron preparations during lactation, the second subgroup - 51 children whose mothers did not receive iron subsidies. An assessment of the somatic status, a general clinical examination was carried out. Results and Discussion.Based on the data obtained using the statistical method of analysis, it was found that iron deficiency in the antenatal period significantly increased the frequency of premature birth, caused a deficiency of birth weight, heart disease, and led to a high frequency of viral infections in pregnant women. In newborns, from mothers who did not receive the iron preparation, a high frequency of latent iron deficiency (LID) and iron deficiency anemia (IDA) was noted. Newborns from the comparison group, according to the results of laboratory diagnostics, were treated with LID and IDA, however, lower indicators of physical development, NPR remained until 6 months. In the postnatal period, there was a direct correlation between the prophylactic intake of iron preparations by a nursing mother and the occurrence of latent iron deficiency and IDA in a child. Conclusion. The data obtained allow us to speak about the high effectiveness of preventive iron supplementation by a pregnant and lactating woman, to reduce the risk of pathological pregnancy and childbirth, affecting the indicators of physical and neuropsychic development (NPD) of a newborn and an infant. Even with the timely elimination of iron deficiency in a newborn, the delay in physical and NPR is noted up to 6 months. The analysis of the effect of iron deficiency in pregnant and nursing mothers on the course of the antenatal period, childbirth and the state of the child’s health dictates the need for prevention from the standpoint of a personalized approach.

Improvements to the procedure for determination of the residual lifetime of railway vehicles

Existing research concerning the extention of the service life of various types of railway vehicles and assessing its remaining lifetime has been reviewed and analyzed. It has been established that the vast majority of studies relate to the assessment of the residual lifetime of various types of railway rolling stock based on the results of technical diagnostics and routine tests, as well as the assessment of corrosion wear of supporting elements and vehicles bodies. At the same time, little attention has been paid to the issue of improving existing programs and procedures of complex technical diagnostics. It was determined that the set of diagnostics operations for the extension of the service life includes routine tests of a test sample and examination of the technical condition of the metal structure of each railway vehicle for mechanical and corrosive damage.It is proposed to make changes to the existing current programs and procedures in such key sections as: terminology, objects of technical diagnostics and tests, selection of a test sample for routine tests, execution order and methods of technical diagnostics and routine tests, data processing and evaluation of results. A comprehensive approach for assessing the residual lifetime of railway vehicles is also proposed.

ANALISA PENYELESAIAN MASALAH DAN PERBAIKAN ALAT PATIENT MONITOR DI RSUP H. ADAM MALIK MEDAN

Research on patient monitor tools has been carried out. The purpose of this study was to determine the problem of repairing the patient monitor tool. Corrective maintenance is maintenance action taken to overcome damage or congestion that occurs repeatedly, then take corrective action on the tool. Patient monitor is a tool that is used to monitor the patient's physiological condition. The purpose of this study is Troubleshooting (damage) patient monitor tools. Improvements to the patient monitor tool with the results of the study found that troubleshooting was seen through the results of less accurate blood pressure calculations so that it affected the diagnosis process in NIBP (Non Invasive Blood Pressure), Spo2 (Oxygen Pressure Saturation) patients. Incorrect reading of SpO2 results can be affected by sensor damage which when diagnosing patients, Ecg (Electrocardiograph) affects the results of diagnostics made by the instrument on patients, Misdiagnosis can occur due to incorrect placement of electrodes/tappers, damaged electrodes, Temperature (temperature) on the temperature sensor, namely damage to the temperature connector cable and the occurrence of undetected temperature results on the patient monitor tool. The research is that the patient monitor has been functioning properly after checking and repairing. Maintenance of the patient monitor must be routine and scheduled to prevent damage so that the age of use of tools and accessories is longer. Testing and calibration of patient monitor tools, especially on patient monitor parameters, must carry out routine checks on patient monitors, especially patient monitor accessories.

Technology for determining non-humanities university students' cognitive-and-psychological characteristics

Objectives. The purpose of this work was to create a special entrance test for first-year students starting to learn a new foreign language. To achieve the research objective, the study analyzed data on testing language/linguistic proficiency and motivation for learning a foreign language. A range of test parameters identifying both abilities and motivation to learn a foreign language in general, but not related to learning a specific language, were highlighted. The identified parameters were used to inform a questionnaire tested on a group of students, whose level of abilities and motivation had already been ascertained. The findings about students were compared with the already known empirical data to support the improvement of test items.Methods. To describe a special entrance test for first-year students starting to learn a new foreign language in a non-humanities higher education institution, a test technology for identifying certain cognitive, psychological, intellectual, motivational characteristics of a student's language personality was created. The developed test parameters served as the basis for constructing several heterogeneous test blocks.Results. The initial version of the test obtained was verified by pilot testing first-semester-first-year students. Expert assessments of the foreign language potential learning on the part of students were used to evaluate the reliability and validity of the test. A subsequent correction of tasks and responses was carried out in light of the verification results.Conclusions. A recommendation to conduct this kind of testing prior to the first semester with the aim of forecasting the success of foreign-language educational activities of students enrolled in the foreign language study group from the “starter” level is formulated. The results of such diagnostics can be used to draw up personified adaptive training programs within the educational process.

ПЕДАГОГІЧНА ОРТОБІОТИКА ЯК СКЛАДНИК ПРОФЕСІЙНОЇ КОМПЕТЕНТНОСТІ МАЙБУТНЬОГО ВЧИТЕЛЯ

Health for a person as a living being should be an absolute, natural vital value, because the satisfaction of almost all human needs, the quality and durability of his life depends on his level. Only a healthy, vital organism is capable of the full and qualitative interaction of a person with the external environment: with the world of nature and social conditions of existence. However, recently in modern Ukrainian society there has been a rapid deterioration in the health of citizens, children, and youth, which causes the search for new ways to maintain health and a responsible attitude to their own health as value. In this regard, it is relevant to increase the professional competence of the teacher by using the ideas of orthobiotics. In the end, for the teacher, it is important not only to acquire knowledge, skills to take care and consciously relate to their individual health, but also to teach students this. In this case, a powerful mechanism is a personal example. Ortobiotics as a science of self -preservation of human health, offers personality means of practical mastery of the technique of maintaining their own health (physical, mental, and spiritual) to continue the productive, high -quality, optimistic life as long as possible. It is pedagogical orthobiotics that should find its place in the content of professional education, the purpose of which is to form sanogenic thinking, by developing a personal strategy for health care, mastering several methods to prevent, and overcome those situations and conditions that threaten the personal health of the teacher and the collective (pedagogical and student) generally. The purpose of the study is to study the essence and significance of orthobiotics as a technology that contributes to the preservation of health, for long -term activities and ideas about this among students at a pedagogical university as future teachers. The results of pedagogical diagnostics have shown that many students do not have sufficient knowledge about orthobiotics, and their current state of health leaves much to be desired. This indicates that there is not enough professional training and healthcare skills for students as future teachers, that motivation to increase the level of healthcare culture is insufficient. Thus, it is necessary to enrich the content of the professional and practical training of future specialists with healthcare technologies and pay more attention to the formation of a culture of their own health and motivation for maintaining a healthy lifestyle. Key words: health, healthcare, orthobiotics, the competence of the teacher.

Current approach in cases of persistence and recurrence of primary hyperparathyroidism

Primary hyperparathyroidism (pHPT) is now diagnosed much earlier and is often asymptomatic. Biochemically mild pHPT is characterized by small parathyroid adenomas (NSDA) and the results of localization diagnostics as well as surgical treatment are poorer. The frequency of redo surgery is 3-14% in large registries. The planning of areoperation is no different from the basic principles for the first intervention. Diagnosis and differential diagnoses must be checked. This is followed by areview of the first operation and the associated histology as well as imaging and the course of parathyroid hormone (PTH) values. The next step is to check whether the reoperation is necessary. Most patients still have comprehensible indications that correspond to the guidelines and also ex-post. In contrast to the first intervention, there is always aneed to attempt to localize the NSDA. The first procedure is asurgically performed ultrasound. Other localization options are MIBI-SPECT scintigraphy, 4D-CT and FEC-PET-CT, with the latter having the highest sensitivity. There is aclear relationship between higher case numbers and better surgical outcomes. Personal experience is decisive and in terms of predicting success this is even more important than the results of localization procedures. The goal of maximizing the outcome and minimizing morbidity justifies what is from the perspective of those affected probably the most important requirement for the future: no redo surgery for HPT outside of ahigh-volume center.

Reasons for allergology consultations prior to COVID-19 vaccination and their outcomes : Two-year experience of an allergy center in North Rhine-Westphalia

To counteract the coronavirus disease 2019 (COVID-19) pandemic, several severe acute respiratory syndrome coronavirus type2 (SARS-CoV-2) vaccines have been licensed since December 2020. Shortly after the start of the vaccination campaigns, occasional allergic reactions related to vaccines were described, thus, leading to concerns in many patients with ahistory of allergies. The aim of this work was to evaluate which anamnestic events represented areason for an allergology work-up before COVID-19 vaccination. Furthermore, the results of the allergology diagnostics are described. We performed aretrospective data analysis of all patients who presented at the Center for Dermatology, Allergology and Dermatosurgery of the Helios University Hospital Wuppertal during the years 2021 and 2022 for allergology work-up prior to COVID-19 vaccination. Demographic data, allergological history, reason for the consultation in the clinic and results of allergology diagnostic tests including reactions after vaccination were included. Atotal of 93patients presented for allergology work-up with COVID-19 vaccines. In about half of the cases, the reasons for the presentation to the clinic were doubts and concerns about allergic reactions and side effects. In all, 26.9% (25/93) of the presented patients had not previously received aCOVID-19 vaccine yet and 23.7% (22/93) of patients developed non-allergic reactions after prior COVID-19 vaccine (e.g., headache, chills, fever, malaise). Of the patients, 46.2% (43/93) were successfully vaccinated in the clinic due to acomplex allergological history, while the remaining 53.8% (50/93) were subjected to outpatient vaccination in the vaccination practice. Only one patient with known chronic spontaneous urticaria developed amild angioedema of the lips afew hours after vaccination; however, we do not consider this episode an allergic reaction to the vaccine due to the time delay. Allergic reactions after COVID-19 vaccines are rare, but many patients with apositive medical history of allergies are concerned about allergic reactions after COVID-19 vaccination. Thus, public work by practicing allergologists is important during vaccination campaigns to meet the concerns and fears of the population, especially of patients with allergies in their medical history.

The New Definition and Epidemiology of Extensive Drug Resistant Tuberculosis in 2020

The objective: to study the epidemiology and incidence of XDR tuberculosis given the updated definition.Subjects and Methods. The results of replies to the specialized inquiry by the Russian Ministry of Health about results of microbiological diagnostics and MTB drug susceptibility tests were studied. To assess the incidence of pre-extensive drug resistance, general population data were used, and for extensive drug resistance, data from 8 regions of Russia were used.Results. The incidence of pre-extensive drug resistance was 39,1% [95% CI 38,4–39,8] among tuberculosis cases with rifampicin resistance including 26,8% in new cases [95% CI 25,8–27,9]; among all cases receiving treatment for whom DST results were available, it made 20,2%, including primary resistance in 9,7%. The incidence of XDR among cases with pre-extensive drug resistance was 3,0% [95% uncertainty interval 1,8–5,3] for all cases, including primary resistance in 1,6% [95% uncertainty interval 0,2–5,7].Conclusion. Despite the low incidence of pre-extensive drug resistance, it is expected to increase primarily due to growing resistance to fluoroquinolones. Resistance to innovative drugs, in particular XDR, is not yet a serious problem.

Analysis of professional deficits of teachers of the Republic of Tatarstan

The research relevance is due to the need for regional education systems to develop tools and assessment techniques that allow identifying professional deficits in Russian teachers. This article analyses the results of approbation diagnostics of professional competencies of teachers in the state information system “Electronic Education of the Republic of Tatarstan”. Diagnostic tools were developed by scientific and pedagogical workers of organisations of higher and additional professional education of the Republic in accordance with the provisions of the professional standard “Teacher”.Aim. The present research aims to analyse and summarise the results of the monitoring of professional deficits of teachers of the Republic of Tatarstan in the field of subject, methodological, psychological, pedagogical and regulatory competencies for further building individual development trajectories and targeted professional development programmes.Methodology and research methods. Teachers were tested in their personal accounts in the information system “Electronic Education of the Republic of Tatarstan”. Evaluation materials were divided into blocks that differ in content and purpose in accordance with the labour functions of the professional standard “Teacher”: legal, subject, methodological and psychological-pedagogical blocks. Each option consisted of 25 tasks. The maximum participant in the diagnostics could score 100 points. The interpretation of the level of professional deficits was carried out in accordance with the scale recommended by the Ministry of Education. The results of the diagnostic work were processed using visual and mathematical- statistical methods implemented within the tools and libraries of the Python programming language.Results and scientific novelty. The authors identified the target blocks corresponding to certain labour functions of a teacher. When performing the tasks from the identified target blocks, teachers experience the greatest and least professional difficulties. The authors identified control and measuring materials, which are associated to be the most difficult. The deficit level was analysed among subject teachers. The authors separately analysed the results of testing in the field of inclusiveness and individualisation of the educational process, the formation of digital competencies in the context of teachers of the humanities, natural sciences and primary school teachers. A correlation analysis of block diagnostic results was carried out. The influence of the territorial factor on the differentiation of test results was analysed. Difficulties, equally pronounced for both urban and rural teachers, in most cases are associated with the unwillingness of teachers to fully solve professional tasks in the formation of functional literacy of schoolchildren, the development of inclusive and personalised learning; with insufficient knowledge of the psychological and pedagogical features of the development of children of different ages to resolve conflict situations.Practical significance. The results obtained and the conclusions drawn can become the basis for the preparation of methodological recommendations in the field of organising the educational environment for advanced training courses, taking into account teachers’ urgent needs.

Rare clinical cases of tularemia

The most common clinical form of tularemia in Europe is ulcerative bubonic , which has a summer-autumn seasonality . When infected with water and food , the development of oropharyngeal and abdominal forms is possible . The rarity of registration of such forms is associated not only with the low frequency of such cases of infection , but also with the complexity of diagnosing diseases with an atypical clinic . Important for the correct diagnosis are the results of specific laboratory diagnostics and a qualitatively collected epidemiological history . The results of zooparasitological monitoring allow assessing the risk of infection in certain territories . The article provides descriptions of two cases of severe abdominal tularemia , registered in autumn 2021 – winter 2022 in the Republic of Karelia , which has been one of the most disadvantaged regions of Russia in recent years . In the first case , in a 15-year-old boy , the disease began acutely , the main symptoms were high fever , abdominal pain , vomiting , loose stools , foci of skin hyperemia with clear uneven edges without infiltration in the left knee joint and right inguinal region , hepatomegaly , mesoadenitis . In indirect gemagglutination reaction with tularemia diagnosticum on the third day from the onset of the disease antibodies in titer 1:640. Infection probably occurred when eating food during a trip to the forest zone of the city , where infected rodents were previously detected . In the second case , a 17-year-old girl living in a village was diagnosed with a peritonsillar abscess 3 weeks before a sharp rise in temperature , abdominal pain , vomiting and loose stools . Later he developed renal and hepatic insufficiency , polyserositis . The antibodies titer was 1:320 after 3 weeks and 1:2650 after 5 weeks . Infection probably occurred through consumption of rodent-contaminated v egetables .

Влияние самооценки и профессиональной деятельности сотрудника органов внутренних дел друг на друга

The study of the features of self-assessment of employees of the internal affairs bodies of the Russian Federation is of scientific interest, since for the effective performance of official duties, an employee must have a certain level of physical development, moral qualities, the ability to adapt, the ability to improve and self-development in the system of internal affairs bodies of the Russian Federation, as well as the ability to adequately assess their potential. The article analyzes and discusses the results of a study of the self-assessment of employees of the internal affairs bodies of the Russian Federation and the correlation of the types of self-assessment of employees with their professional activities. The study was conducted on the basis of the territorial bodies of the Ministry of Internal Affairs of Russia of the Smolensk region. The respondents were 80 employees from among the middle and senior commanding staff of the Ministry of Internal Affairs of Russia. The article shows that the success of professional activity is conditioned by high adequate self-esteem and normal self-esteem. To improve the efficiency of the service, the basis of the actions of psychologists and heads of the Ministry of Internal Affairs of Russia aimed at achieving compliance of employees with the tasks of activity should be based on the results of psychological diagnostics of self–assessment of employees of the internal affairs bodies of the Russian Federation (hereinafter - the ATS).

Physical health and prospects of its improvement for music students of the Kharkiv I. P. Kotlyarevsky National University of Arts

Statement of the problem. Objectives, material, and methods of the research. Health and healthy lifestyle of student young people, including those who studies in the sphere of art, is the mortgage of their capacity and success in future professional activity. In order to improve the quality of educational work on the discipline “Fundamentals of physical education and a healthy lifestyle”, the studies and estimation of main parameters of psychical, social and physical health of music students of the Kharkiv I. P. Kotlyarevsky National University of Arts were undertook. The 127 students of master’s degree course took part in the study, among them 61 students of the 2019 graduating class and 66 graduates of the 2020. On the first stage of our investigation the diagnostic research methods were used; on its second phase the mathematical statistic methods were applied. The results of diagnostics of individual psychical, social and physical health (without the account of gender approach) are analysed for the students-musicians of master’s degree separation 2018/2019 and 2019/2020 school. In the course of the study, the results of testing the mental, social and physical health of master students (without taking into account the gender approach) of two faculties of the University – the musical performance and orchestral ones were analyzed. The comparative quantitative analysis on several various indexes of quality of music students health separating 2018/2019 and 2019/2020 academic years, was conducted. Also, the cluster analysis with application of mathematical processing of the statistic data, taking into account the gender differentiation, was undertook to reveal the current state of health and perspectives of its perfection for male and female groups of the students. Research results. A comparison and grouping of five indicators determining the diagnosis of a student’s physical health (anthropometric, respiratory, strength, cardiovascular, restorative) showed that in the 2019/2020 academic year, students-musicians of the master’s degree of the Kharkiv I. P. Kotlyarevsky National University of Arts were inferior to the students of 2018/2019 year in terms of body weight, hand strength, vital capacity of the lungs, and an integral indicator of physical health. Positive results were recorded only for two indicators – cardiovascular and recovery. A high level of physical health was not revealed, however, the students of orchestral faculty have the better results than the students of the performance and musicology faculty. Conclusion. According to the results of research, it becomes obvious that the way to improve the physical health of music students can be not only the usual increase of training in academic group classes, but also a qualitative change in the planning of practical classes in physical education based on the principle of individual differentiation: choosing a direction, determining the content and ratio of physical exertion for each cluster subgroup of male and female students. When differentiating work programs of physical training of music students, it should be taken into account that the effect on the body of various exercises is not the same and requires individual approach depending on the qualitative characteristics for each subgroup determined by cluster analysis.

Structural phenomenological concept of monitoring the load-bearing capacity of structural elements of composite materials

The authors demonstrate the potential of a methodological approach for monitoring the damage kinetics and evaluating the load-bearing capacity of composite structural elements based on the method of acoustic emission. This methodology was developed by specialists of the Blagonravov Mechanical Engineering Research Institute of the Russian Academy of Sciences. The methodology was implemented for a fatigue test of an aircraft panel represented by a complex hybrid structure with a lining made of layered composite and a cellular internal structure of aluminum foil with polymeric filler that has a continuous layered structure in the gripping area. Fatigue tests were carried out at 4 Hz from the zero-loading cycle with an amplitude of 145 kN. To record the accumulation of damages, R15–AST transducers by Mistral (USA) and an A-line 32D 8-channel acoustic emission system by Interunis-IT LLC were used. Comparing the weight content of location impulses with their threshold values in energy clusters characterizing the kinetics of micro-, meso-, and macro-damages of the composite material structure made it possible to determine the bearing capacity of the aircraft panel at respective stages of damage kinetics. The results of the acoustic emission diagnostics are given for the examined aircraft panel during cyclic loading, including the coordinate location of acoustic emission sources, accumulation of acoustic emission events by channels, the dynamics of partial activity changes, and weight content of location impulses at damage evolution stages of a composite material. Therefore, the acoustic emission diagnostics of the aircraft panel made it possible to identify the areas of intensive damage accumulation in the hybrid structure of the panel and control the actual bearing capacity by defining the extent of its damages at various scale and structural levels during cyclic loading. The described methodology of using acoustic emission diagnostics for monitoring the damage kinetics and actual bearing capacity of highly loaded composite elements extends the research potential of the acoustic emission method.

Наглядная модель как культурное средство детей дошкольного возраста

<p>This study is aimed at testing the hypothesis of the relationship between visual modeling and the development of arbitrariness. The results of an empirical study conducted on a sample of 149 children (44,3% boys) aged 53 to 70 months (M=62,8; SD=3,53) are presented. The "Schematization" technique and subtests of the NEPSY II battery were used to diagnose executive functions. The results showed that schematized representations act as cultural means of regulating the behavior of preschoolers. A correlation was found between the results of the execution of the methodology for schematization by children of the senior kindergarten group and the results of diagnostics of the development of executive functions of preschoolers, both in the senior kindergarten group and in the preparatory group (longitudinal study). The results showed that in boys, the structuring of behavior control mechanisms is associated with the processes of schematization using signs. In girls – with the processes of schematization with the help of directions. It is suggested that the development of the mechanism of regulation of behavior with schematized representations in preschoolers follows two lines: 1) along the line of strengthening the emerging links and 2) along the line of their differentiation.</p>
