Politeness Theory: In Search of Effective Research Methodology in Western Sociopragmatics
Authors: Rossikhina M. Yu. , Ikatova I. I.
Published: March 2022

The present paper provides a review of the most discussed issues with regard to creating a universal formal approach to study the politeness theory. What we see now is the lack of a proper metalanguage, and proliferation of various theoretical approaches: the presentday terminology describing polite behavior is represented by a variety of concepts: ‘appropriateness’, ‘saving face’, ‘face constituting’, ‘rapport management’ etc. along with a great number of diverse discursive practices in different cultures makes it quite a challenge to provide a coherent overview of politeness strategies. However, despite considerable fragmentation in politeness theory research we can observe certain consistency in the chosen methods for the interpretation of empirical material and experimental data. Firstly, specialists avoid using the term ‘politeness’ in theoretical reasoning due to abundance of peripheral semantic components realized in the speech of language users from different cultures, and restrict its employment to the interviewing of respondents. To interpret certain behavior as (im)polite and analyze its perception, the impact of expectations and norms is increasingly taken into consideration. Although research of authentic verbal interaction based on discourse analysis is still quite common, a greater focus on paralinguistic aspects of communication can be predicted. Research findings in the politeness theory will be more and more applied to discursive practices to benefit the health and welfare of the society.
Zoologic Metaphor as a Means of Characterizing a Child in American and British Linguocultures
Authors: Korshunova A. I.
Published: March 2022

This paper examines the issue of using zoologic metaphors as a means of verbalizing group/individual perception of children by adults. The research was carried out on the basis of a survey conducted among representatives of American and British cultures, as well as on the examples from media discourse, namely The New York Times and The Times. This approach allows us to focus not only on the child perception by Americans and Britons as a whole, but also by individuals. The purpose of this study is to identify, analyze and compare the context of the use of zoologic metaphors employed to conceptualize childhood experiences by representatives of American and British linguocultures.
The Concept CHINA in the Minds of Native Russian Speakers (Based on the Material of an Associative Experiment)
Authors: Zhang Yan
Published: March 2022

The article is dedicated to a study on the concept CHINA in the minds of native Russian speakers and the national worldview that has been formed at the present time. The relevance of this article is determined by the research interest in the significance attached to the concept CHINA worldwide and the need to identify specific cultural features of the Chinese national mentality as viewed from the outside. The relevance of the concept CHINA as the object of our paper is accounted for by the role of China in the contemporary world, as well as by political, economic, cultural, scientific, and other contacts between the Chinese and Russian peoples. The results of the free associative experiment on the stimulus “China” are used as a source of material for the reconstruction of the concept. The participants of the experiment were students of Kazan Federal University (KFU); teachers of KFU of various specialties; translators, engineers, employees from different enterprises and institutions in the city of Kazan; students of the preparatory department for foreign students of the Xian Petroleum University (foreign students from Russia).The aim of the article is to identify the cognitive features of the concept CHINA, and describe its structure in the minds of native Russian speakers. While achieving this aim, the following tasks were performed: 1) conducting a free associative experiment; 2) analyzing the reactions of the informants in the associative experiment; 3) identifying the parameters of reactions according to cognitive characteristics; 4) building the structure of the associative field “China”; 5) describing and identifying the concept CHINA in the minds of native Russian speakers.It has been shown that the core of the associative field includes associates about Chinese culture and its people. A high-frequency word “Panda”, seems to symbolize China. Almost all the respondents emphasize Chinese culture and the people’s mentality. The core of the associative field consists of the units concerning public life, health, and famous places in China. Tea exists in the minds of native Russian speakers as a favorite drink and a precious gift. The periphery of the associative field includes words related to Chinese politics, the army, and bilateral interstate relations. The cognitive signs identified in the free associative experiment on the stimulus “China” demonstrate Russian people’s great interest in all the aspects of Chinese culture and create a multifaceted idea of China.
The Political Marginalization as a Communicative Strategy of Power Domination in Political Discourse
Authors: Alexeyev A. B.
Published: March 2022

The article is dedicated to the study of political marginalization viewed as a communicative strategy, aimed at retention or attainment of political power. Political discourse, despite the perceptible tendency towards personalization of the political communication particularly noticeable in politainment, is defined as a predominantly institutional type of discourse in which the dyad ‘agent – client’ plays an important role. From the traditional standpoint of view, it is believed that agents have discursive power while clients have none. However, as the undertaken research shows, it is quite difficult to draw a distinct line between agents and clients in political discourse. The point is that using the strategy of marginalization, politicians can present themselves as non-politicians (i.e. non-agents), untypical (atypical) politicians, for example women politicians, politicians holding on to minority political views, etc. At the same time, the strategy in question is most likely unrestricted by political forms of marginalization in the sense that it can correspond to the politician’s search for selfidentification with marginal social groups whose rights are infringed upon, including national minorities and LGBT. Furthermore, even those social groups which, in fact, have long ceased to be marginal in the Western world (e.g. women) can be exploited by marginal politicians who prefer to characterize them as people who are not enjoying equal rights with elite, privileged representatives of the society (e.g. men). Thus, the study of marginalization presupposes the analysis of the complex structure of social relationships, unveiling manipulative aspects of marginalization (NB: the politician’s self-representation as the non-politician should almost always be considered as an instance of manipulation) and exploration of linguopragmatic aspects of marginalization.
Footloose Workers in Times of Calamities: A Case Study of the 2018 Kerala Floods
Authors: Rajan S. Irudaya , Suresh Arya , Irudayarajan Rohit
Published: March 2022

Kerala, the southernmost state in India, much researched for its high standard of living and a model of development, largely dependent on international remittances, experienced one of its worst floods in 2018. The state also experiences a peculiar type of labor crisis; where the local population migrates internationally, attracting interstate migrants to compensate for the labor deficit. However, in times of calamities like floods, these unorganized laborers are the worst hit and still the last priority. The media widely reported their mass exodus, unhygienic living conditions, and mistreatment in relief camps during the floods, though the policy responses have been unsatisfactory to date. The paper tries to evaluate the role of inter-state migrants in the socio-economic profile of Kerala and comments on the necessity to include them as a priority in the migration policy discussions, particularly in light of the state’s extreme proneness to natural disasters.
‘Changed Landscape’ of an ‘Arab Place:’ A Study of an Interpellated Realm in Karmi’s Return
Authors: Aamir Rabiya
Published: March 2022

As the episodes of forced evictions in the environs of Jerusalem gain momentum even amidst a global pandemic at the dawn of the third decade of the twenty-first century, this paper studies the individual narrative of an anglicized Arab woman, Ghada Karmi, who was forced to leave the place of her birth and childhood more than eighty-three years ago. Engaging Althusser’s theory of ideology and interpellation, this paper examines this recurring pattern of brutal practice as an environmental ethical concern. By stating the postcolonial environmental ethic of her homeland through her latest memoir, Karmi questions unexamined idées reçues,1 preexisting units of information, that impede the process of any solution for the Palestinian predicament. Understanding the need for social justice and decolonization, as manifested in Karmi’s memoir, this conceptual paper investigates how she presents her right to return to the land of her birth, how she problematizes the ongoing marginalization, erasure, and Nakba of her land, both by external as well as internal factors, and how she states the environmental ethic of her place.
Global Developments in Climate Policy and Migration Policy: Can the UN Be a Base to Create an Adequate Legal Framework?
Authors: Güneş Burak , Karaman Haydar
Published: March 2022

This commentary discusses how the latest resolution adopted by the UN Human Rights Council (UNHRC), recognizing “The Human Right to a Safe, Clean, Healthy and Sustainable Environment,” paves the way for a juridico-political argument over Climate-induced problems. First and foremost in this piece, the climate change-related refugee movement is examined from a critical perspective. Additionally, the paper also asserts that the issue of ‘climate refugees’ is neglected, and climate-induced migration challenges the current international migration framework. Therefore, this commentary seeks to investigate the impacts and relevance of international law and politics on ‘climate refugees’ in the case of the Republic of Haiti. Lastly, the paper offers practical solutions for those displaced by environmental factors.

Authors: De Lima Joao Batista
Published: March 2022

Em 2010 foi promulgada a Lei de Segurança de Barragens que tem dentre seus objetivos implementar uma cultura de manutenção preditiva e preventiva nas barragens brasileiras. Este artigo visa descrever as principais manifestações patológicas na Barragem de Jucazinho e seus possíveis tratamentos. A metodologia envolve: a revisão da literatura; a caracterização da barragem de Jucazinho; a compilação das anomalias identificadas no corpo do barramento; e a proposição  de  técnicas  para  recuperação.  Através do relatório  da consultoria contratada pelo Departamento de Nacional de Obras Contra as Secas (DNOCS) foram identificadas as seguintes anomalias na estrutura: presença de bexigas no extravasor principal, onde o tratamento dar-se-á pela aplicação de uma argamassa de alta resistência; danos na estrutura da bacia de dissipação, onde será construído um salto em esqui ao final do extravasor principal;  fissuras e trincas observadas ao longo do barramento que serão tratadas com injeção de resina poliuretânica; e deposição de material fino além de infiltração na galeria, que serão corrigidas com injeção de argamassa a cada 3,0 m  ao longo do barramento até o estrato rochoso. Ao final deste artigo, fica evidente a necessidade de adoção de uma sistemática de inspeções de segurança para identificar prematuramente possíveis manifestações patológicas.
Análise de Viabilidade na Substituição das Resinas Poliamida e Maleica por Poliuretana Em Tintas da Linha Gelo na Flexografia.
Authors: Recco Luiz Henrique Da Silva , Marques Carolina Resmini Melo , Melo Aline Resmini , Das Neves Josiane Da Rocha Silvano
Published: March 2022

A tinta flexográfica é composta por imagens com múltiplas cores, impressas com o objetivo de embelezar e dar resistência ao substrato onde é impressa. As tintas são estruturadas principalmente por resinas, pigmentos e solventes, sendo necessária a adição de aditivos para atender uma resistência físico-química específica da linha, como por exemplo na linha gelo, a resistência a gordura e umidade. Tendo em vista que as resinas poliamida e fumárica são utilizadas para a produção desta, e por serem mais caras que outras resinas, o presente trabalho visa a possibilidade da substituição dessas pela resina poliuretana, visando manter a resistência físico-química da linha gelo, além da diminuição de custo de produção. Utilizou-se um plano estratégico para o desenvolvimento de uma nova formulação, verificando a influência de cada componente químico na propriedade da tinta. Os resultados do trabalho apontam que a substituição das resinas fumárica e poliamida pela poliuretana mostra-se uma alternativa eficaz para redução do custo de produção das tintas da linha gelo, além de manter a resistência a gordura e umidade. Propriedades primárias como secagem, viscosidade, brilho, cobertura e fricção não foram comprometidas com as alterações necessárias nas formulações, o que veio a confirmar a qualidade da tinta desenvolvida.

Published: March 2022

Neste artigo analisa-se o comportamento dos níveis de sobretensão no lado primário das redes aéreas de distribuição de energia na situação de descarga atmosférica, levando em considerando o fenômeno da ionização do solo nos aterramentos elétricos. Para esse fim, duas formulações da resistência de aterramento sob o efeito da ionização foram avaliadas: o Modelo Dinâmico e o Modelo Geométrico. O equacionamento destes modelos foi incorporado mediante rotinas Models no programa Alternative Transient Program (ATP). O caso de estudo correspondeu a um trecho de rede de distribuição do tipo compacta, com parâmetros reais praticados pelas concessionárias de energia. As simulações foram executadas considerando três situações: 1 - sem levar em consideração o fenômeno da ionização do solo, sendo o aterramento representado por uma resistência de valor constante (situação comumente encontrada na prática); 2 - considerando a ionização do solo pelo Modelo Dinâmico; e 3 - considerando a ionização do solo pelo Modelo Geométrico. Foi constatado que os efeitos da ionização alteram drasticamente o comportamento da resistência de aterramento durante o período transitório da descarga, variando sensivelmente seu valor. Consequentemente, os resultados sinalizaram para uma diminuição significativa nos níveis de sobretensão nas estruturas da rede. Desta forma, o trabalho vem a contribuir para uma análise mais realista dos processos transitórios que acontecem nas redes de distribuição, decorrentes dos efeitos das descargas atmosféricas.

Background: Hyperthyroidism was long considered a protective factor for the development of thyroid cancer. The association between hyperactive thyroid and cancer was rare. More recent studies have highlighted an association between hyperthyroidism and development of cancers, especially thyroid cancer. Given the lack of publication on the association of hyperthyroidism and thyroid cancer in the Democratic Republic of Congo (DRC), the present study was carried out to confirm the existence of this association in Congolese hospitals. Methods: This is a retrospective and descriptive study, which involved 106 cases of thyroid cancer recorded in the anatomopathology registers of four laboratories in the city of Kinshasa between 2005 and 2019. The p-value <0.05 was considered as the threshold of statistical significance. Results: Out of 106 cases of thyroid cancer, the association of hyperthyroidism and thyroid cancer was found in 5 cases (4.7%) (3.6% for women vs. 9% for men). The mean age of patients with this association was 51 ± 11 years. Papillary carcinoma (two cases), follicular carcinoma (two cases) and lymphoma (one case) were the types of cancer encountered. Etiologically, toxic multinodular goiter (four cases: 80%) and toxic adenoma (one case: 2%) were found. Conclusion: There is an association between hyperthyroidism and thyroid cancer in the Congolese hospital setting. There is a predominance of the female gender. There were an equal number of papillary and follicular carcinomas. With this study, we hope to encourage clinicians to thoroughly evaluate any suspicious nodule associated with hyperthyroidism.
Effect of Tubulin Self-Association on GTP Hydrolysis and Nucleotide Exchange Reactions

Published: March 2022

Tubulin nucleation, microtubule (MT) assembly, stability, and dynamics depend on GTP hydrolysis and nucleotide exchange reactions. We investigated how the self-association of isolated tubulin dimers affects the rate of GTP hydrolysis and the equilibrium of nucleotide exchange. We used HPLC to determine the concentrations of GDP and GTP and thereby the GTPase activity of SEC-eluted tubulin dimers in assembly buffer solution, free of glycerol and tubulin aggregates. When GTP hydrolysis was negligible, the nucleotide exchange mechanism was studied using HPLC for determining the concentrations of tubulin-free and tubulin-bound GTP and GDP and by SAXS and cryo-TEM. We observed no GTP hydrolysis below the critical conditions for MT assembly, despite the assembly of tubulin 1D curved oligomers and single rings, showing that their assembly did not involve GTP hydrolysis under our conditions. Under conditions enabling spontaneous slow MT assembly, a slow pseudo-first-order GTP hydrolysis kinetics was detected, limited by the rate of MT assembly. Nucleotide exchange depended on the total tubulin concentration and the molar ratio between tubulin-free GDP and GTP. We used a thermodynamic model of isodesmic tubulin self-association, terminated by the formation of tubulin single-rings to calculate, at each tubulin concentration, the distributions of single rings, 1D oligomers, and free dimers, and thereby the molar fractions of dimers with exposed and buried nucleotide exchangeable sites (E-sites). Our analysis shows that the GDP to GTP exchange reaction equilibrium constant was an order-of-magnitude larger for tubulin dimers with exposed E-sites than for assembled dimers with buried E-sites.
Multiscale simulations identify origins of differential carbapenem hydrolysis by the OXA-48 β-lactamase

Published: March 2022

OXA-48 β-lactamases are frequently encountered in bacterial infections caused by carbapenem-resistant Gram-negative bacteria. Due to the importance of carbapenems in treatment of healthcare-associated infections, and the increasingly wide dissemination of OXA-48-like enzymes on plasmids, these β-lactamases are of high clinical significance. Notably, OXA-48 hydrolyses imipenem more efficiently than other commonly used carbapenems, such as meropenem. Here, we use extensive multiscale simulations of imipenem and meropenem hydrolysis by OXA-48 to dissect the dynamics and to explore differences in reactivity of the possible conformational substates of the respective acylenzymes. QM/MM simulations of the deacylation reaction for both substrates demonstrate that deacylation is favoured when the 6α-hydroxyethyl group is able to hydrogen bond to the water molecule responsible for deacylation, but disfavoured by increasing hydration of either oxygen of the carboxylated Lys73 general base. Differences in free energy barriers calculated from the QM/MM simulations correlate well with the experimentally observed differences in hydrolytic efficiency between meropenem and imipenem. We conclude that the impaired breakdown of meropenem, compared to imipenem, which arises from a subtle change in the hydrogen bonding pattern between the deacylating water molecule and the antibiotic, is most likely induced by the meropenem 1β-methyl group. In addition to increased insights into carbapenem breakdown by OXA β-lactamases, which may aid in future efforts to design of antibiotics or inhibitors, our approach exemplifies the combined use of atomistic simulations in determining the possible different enzyme-substrate substates, and their influence on enzyme reaction kinetics.

Published: March 2022

Cu3N and Cu3PdN nanocrystals are attractive materials with numerous applications ranging from optoelectronics to catalysis. However, their chemical formation mechanism and surface chemistry are unknown or contested. In this work, we first optimize the synthesis and purification to yield phase pure, colloidal stable Cu3N and Cu3PdN nanocubes. Second, we elucidate the precursor conversion mechanism that leads to the formation of Cu3N from copper(II) nitrate and oleylamine. We find that oleylamine is both the reductant and nitrogen source. Oleylamine is oxidized to a primary aldimine and the latter reacts further with oleylamine to a secondary aldimine, eliminating ammonia. Ammonia reacts with Cu(I) to form Cu3N. Third, we investigated the surface chemistry of the nanocrystals using solution NMR spectroscopy and X-ray photoelectron spectroscopy (XPS). We find a mixed ligand shell of aliphatic amines and carboxylates. The carboxylate is produced in situ during the synthesis. While the carboxylates appear tightly bound, the amines are easily desorbed from the surface. Finally, we analyze the optoelectronic properties by UV-Vis and XPS. Doping with palladium decreases the bandgap but the material remains a semiconductor. These results bring insight into the chemistry of metal nitrides and will help the development of other metal nitride nanocrystals.

Published: March 2022

A statistical study on C, H, N elemental analysis for 5 small organic compounds at 18 independent service providers across multiple countries demonstrates variation in the returned results that is outside journal guidelines (0.4%) in greater than 10% of measurements for C and N while H analyses return a high proportion of results within guidelines. The results clearly indicate that a deviation of 0.4% is not a realistic journal requirement for synthetic samples with the variability attributed to random error in the data collection process.
Polyphenolic Promiscuity, Inflammation-coupled Specificity: Whether PAINs Filters Mask an Antiviral Asset
Authors: Sheridan Rick , Spelman Kevin
Published: March 2022

The Covid-19 pandemic has elicited much laboratory and clinical research attention on vaccines, mAbs, and certain small-molecule antivirals against SARS-CoV-2 infection. By contrast, there has been comparatively little attention on plant-derived compounds, especially those that are understood to be safely ingested at common doses and are often commonly consumed in the diet. With broader scope for assays and trials against a diverse array of viral infections, we review elucidations of the pharmacokinetic mechanisms of polyphenolic compounds over the past two decades and survey their putative frequent-hitter behavior. Many polyphenols are indeed promiscuous binders, suggesting a candidate mechanism of non-specific inhibition combined with inflammation-targeting specificity. Since such a specificity mechanism combined with promiscuity poses a possible pathway of inhibiting viral replication uniquely in infected tissue, we highlight pre-clinical studies of polyphenol aglycones that reduce virion replication. It is hoped that greater awareness of the potential specificity of polyphenolic activation to sites of pathogenic infection will spur renewed research and clinical attention on assaying and trialing against several infectious viral diseases.

Published: March 2022

An all-solid-state battery in which the organic liquid electrolyte of a lithium-ion battery (LIB) is replaced with an inorganic solid electrolyte is a candidate for next-generation rechargeable batteries. Although the solid electrolyte has high conductivity, the charge and discharge characteristics are inferior to those of conventional LIBs. To achieve the high performance of all-solid-state batteries, it is necessary to grasp the phenomena peculiar to the composite electrode that uses the solid electrolyte. This study analyses the three-dimensional structure of the composite electrode in an all-solid-state battery using a laboratory-built cell capable of performing electrochemical and X-ray computed tomography (CT) measurements while monitoring stack pressures. The dependencies of stack pressure on the porosity, contact area, and tortuosity of the composite electrodes are quantitatively analysed to evaluate their effects on the electrochemical properties. The CT observation reveals that there is insufficient contact between the active material and the solid electrolyte in a plane perpendicular to the pressure direction. The contact interface is found to be a key parameter for the charge/discharge characteristics.
Age-adjusted COVID-19 Mortality Rates by Demographic Groups
Authors: Hernández-Murillo Rubén
Published: March 2022

A noteworthy aspect of the SARS-CoV-2 (COVID-19) pandemic is the disproportionate effect of the virus on people of different age groups. The elderly have a higher risk of mortality than working-age adults, and they also face a higher mortality risk than children (CDC, 2020). Figure 1 shows the monthly age-specific crude mortality rates (CMRs) by age group for the United States during 2020 and 2021. One can see that the mortality rates of children (0 to 17 years) and young adults (18 to 29 years) are essentially flat, with 1 death per million children and at most 14 deaths per million young adults. The mortality rate of intermediate adults (30 to 49 years) is somewhat higher, as is the mortality rate of older adults (50 to 64 years). However, the figure illustrates the striking disparity between the mortality rate of elderly adults (65 years or older) and the rest of the population, including children: The mortality rate of the elderly peaked at 1,577 deaths per million in January 2021. The mortality rate for the overall population is the population-weighted average of the rates across all five age groups.

Authors: Chen Dongyun , Lv Bing , Liu Rongyan
Published: March 2022

The emergency department is a department that is crucial for medical institutions. It is mainly responsible for rescuing critically ill patients and dealing with all kinds of public health emergencies. There are significant differences in the working environment and working mode between the nurses in emergency departments and those of other departments. They tend to come into contact with various occupational risk factors, resulting in high incidence of occupational hazards and accidental injuries. Therefore, it is necessary to analyze the common occupational risk factors of nurses in the emergency department and propose protective measures to ensure that these nurses are able to provide nursing services safely and effectively.

Published: March 2022

Objective: To study the application value of high-quality nursing intervention in patients with cirrhotic ascites. Methods: From February 2018 to February 2020, 80 patients with cirrhotic ascites, treated in Yancheng No.1 People’s Hospital, were selected as the subjects for this study. The patients were divided into two groups based on the type of nursing intervention: a routine group and an observation group, with 40 cases in each group. The routine group received routine nursing, and the observation group received high-quality nursing intervention on the basis of routine nursing. The nursing effects and adverse reactions of the two groups were observed and compared. Results: The total effective cases in the observation group were 39 cases, with a total effective rate of 97.5%; the total effective cases in the routine group were 33 cases, with a total effective rate of 82.5%. The total effective rate of the observation group was significantly higher than that of the routine group (P < 0.05). In the routine group, there were eight cases of adverse reactions, in which the incidence of adverse reactions was 20.0%, whereas there were only two cases of adverse reactions in the observation group, in which the incidence of adverse reactions was 5.0%. The incidence of adverse reactions in the observation group was significantly lower than that in the routine group (P < 0.05). Conclusion: The application of high-quality nursing intervention in patients with cirrhotic ascites can improve the nursing effect and reduce the occurrence of adverse reactions; thus, it should be popularized in clinical settings.

Objective: To analyze the efficacy of hyperbaric oxygen at different pressures in the treatment of sudden deafness. Methods: Eighty-two patients with sudden deafness treated in the Affiliated Hospital of Hebei University from September 2019 to September 2021 were selected as the research subjects. The patients were randomly divided into study group 1 and study group 2, and they were treated with hyperbaric oxygen on the basis of routine treatment, in which the pressure used was 1.8 ATA and 2.2 ATA, respectively. Oxygen was delivered via the pressure stabilizing mask for 60 minutes. The patients received two courses of treatment, each lasting 10 days. The changes in hearing (pure tone audiometry) and the clinical efficacy of both the groups were compared before and after treatment. The data obtained were statistically analyzed using SPSS 19.0. Results: The total effective rate of study group 1 was 90.00%, while that of study group 2 was 76.19%. The differences between the two groups were statistically significant (p < 0.05). Conclusion: For patients with sudden deafness treated with hyperbaric oxygen, the clinical efficacy of 1.8 ATA is more significant than that of 2.2 ATA.

The purpose of the study was to prove the effectiveness of the developed program of physical therapy for women with hypertension based on the indicators of the functional state of the cardiovascular system. Materials and methods. The paper presents an analysis and generalization of modern scientific and methodological literature of domestic and foreign authors according to the Internet and the PubMed resource. A large group of medical and biological methods was used: 6-minute walk test, tonometry, registration of electrocardiogram, electroencephalogram and heart rate variability. Results and discussion. Based on the analysis of literature sources, it was found that in the problem of physical therapy of people with hypertension there are a number of unresolved issues regarding their use for effective recovery and increase adaptability. The program of physical therapy for women with hypertension was developed based on data on the etiology and pathogenesis of the disease, as well as data from previous examinations. That is why the therapies were selected according to their effect on the mechanisms of blood pressure regulation. After physical therapy according to our proposed program, the 6-minute test in women of the main group probably (p <0.05) increased and amounted to 512.52±14.30 meters, which is 105.05 meters more. In women of the comparison group, this figure increased by 50.5 meters. Statistically significant (p <0.05) decreased systolic and diastolic pressure to 128.2±8.9 mm Hg and 82.3±4.1, respectively. In the women of the comparison group, these reductions were not statistically significant. The ratio of sympathetic to parasympathetic activity in terms of heart rate variability changed in women of the main group from 1.7±0.11 to 0.53±0.03 (p <0.05), due to a decrease in sympathetic and increased parasympathetic activity, which also manifested in a reduction in the QT interval of the electrocardiogram. In women of the comparison group, the ratio of sympathetic to parasympathetic activity changed from 1.7±0.18 to 1.04±0.06 (p <0.05). After physical therapy in 100% of cases in women of the main group the power and in 85% the frequency of α-electrocardiogram rhythm decreased, which indicated a decrease in excitability and increased energy intensity of central processes. In women of the comparison group, these figures were 74% and 60%, respectively. Conclusion. The data obtained indicate the feasibility of selected means and methods of physical therapy for middle-aged women with hypertension

The purpose of the study was to determine the features of physical development and level of development of physical qualities of secondary school pupils. Materials and methods. The study involved pupils of Lviv secondary schools. 254 students of 5-8 grades were involved. Theoretical analysis and generalization of data from scientific and methodological literature and Internet resources was conducted in order to study the problematic issues in physical education of secondary school pupils. Pedagogical testing and anthropometric measurements were used in the study. Tests of physical fitness were conducted, namely to assess the level of speed development the test in running 60 m was used, to assess endurance we used running 1500 m and speed and strength indicators were assessed by standing long jump. Assessment of physical fitness was performed according to T. Yu. Krutsevych methods (index method). The speed index was calculated as the ratio of the schoolchildren height to the result in the 60 m run, the speed-strength index was the ratio of body length to the result in the long jump, the endurance index was the ratio of body length and 1500 m to body weight. Results and conclusion. It was found that most of the anthropometric indicators of students in grades 5-8 meet the standards of physical development of middle school children. It was found that in girls and boys of 5-6 grades significant gender differences in the indicator of physical development were not recorded. The growth rates of boys in grades 7-8 significantly outweighed those of girls. The 8th grade girls had slightly higher weights. For pupils of 5-6 grades, the speed is characterized by an average level of development (3.47-3.56 units in girls and 3.68-3.70 units in boys). Speed and power indicators correspond to the average level of development in boys and girls of the 5th grade (1.08 units, 0.94 units, respectively). The average level of speed and strength indicators (1.13 units) was found in the 6th grade boys, and higher than the average level (1.08 units) in girls. The average level of development of speed, endurance and speed-power indicators was recorded in the 7th grade pupils, except for the boys in the speed-power index, where the results correspond to a lower than average level (1.05 units). The 8th grade girls had an average level of speed development (3.40 units), speed and strength indicators (0.99 units) and a low level of endurance (0.8 units). The 8th grade boys showed an average level of development of speed and power indicators (1.15 units), the level of speed corresponds to the level above average of development (3.90 units), and endurance – below the average level (1.09 units)
