Authors: Silva Roberto José , Silva Kaique , Mattos Jonatas
Published: April 2020

O novo coronavírus em humanos desencadeou uma pandemia no mundo, devido a sua fácil transmissão e o intenso fluxo de pessoas e transportes nos dias atuais. O estado da Bahia, com seus 417 municípios e quase 15 milhões de habitantes, teve seu primeiro caso registrado em 06/03/2020. As autoridades sanitárias locais estão em ação, buscando soluções para frear o avanço da COVID-19, minimizar o impacto sobre a população e fornecer precioso tempo para melhor adequação do sistema de saúde. Neste cenário, o entendimento sobre a circulação de pessoas e o sistema de transportes no estado é muito importante para direcionar a tomada de decisões. Esta nota leva em conta a Análise de Inteligência Estratégica para fins de assessoramento estratégico no processo decisório, no caso em tela, visando subsidiar as autoridades sanitárias no estado da Bahia, nas esferas estadual e municipal. Com base em elementos espaciais do sistema de transportes e nos dados das cidades com casos confirmados da COVID-19, foi usada a Geomatemática associada ao SIG, através das ferramentas de análise, que identificou no dia 02/04/2020, 304 municípios com risco alto ou muito alto para ocorrência de novos casos da COVID-19.

A COVID-19 é uma doença produzida pelo vírus SARS-CoV-2. Esse vírus se espalhou rapidamente pelo mundo, o que levou a Organização Mundial da Saúde a classificar a COVID-19 como uma emergência de saúde internacional e, posteriormente, declará-la uma pandemia. O número de casos confirmados, no dia 11 de abril de 2020, já passa de 1.700.000, porém esses dados não refletem a real prevalência de COVID-19 na população, visto que, em muitos países, os testes são quase que exclusivamente realizados em pessoas com sintomas, especialmente os mais graves. Para definir políticas de enfrentamento, é essencial dispor de dados sobre a prevalência real de infecção na população. Os objetivos principais desse estudo são avaliar a proporção de indivíduos já infectados pelo SARS-CoV-2 no Rio Grande do Sul, analisar a velocidade de expansão da infecção e estimar o percentual de infectados com e sem sintomas. Serão realizados quatro inquéritos sorológicos repetidos a cada 15 dias, com amostragem probabilística de nove cidades sentinela, em todas as sub-regiões do Estado. Os testes serão realizados em 4.500 indivíduos em cada inquérito, totalizando 18.000 entrevistas. As entrevistas e testes ocorrerão no âmbito domiciliar. Serão utilizados testes rápidos para detecção de anticorpos, validados previamente ao início da coleta de dados.
COVID-19, Afastamento social, Pesca artesanal e Segurança alimentar: Como esses temas estão relacionados e quão importante é a soberania dos trabalhadores da pesca diante do cenário distópico
Authors: Reis-Filho José Amorim , Quinto Danilo
Published: April 2020

Em um mundo amplamente conectado onde as barreiras sanitárias são insuficientes para conter a disseminação de agentes biológicos prejudiciais à saúde humana, entender como se propagam efeitos de epidemias é um tema de interesse para toda sociedade. Nesse artigo é discutido como a disseminação do Coronavírus no território brasileiro, provocando o afastamento social (AS) entre diversos segmentos da sociedade têm amplificado a precariedade do setor pesqueiro de pequena escala e subsistência e impactado a sua sustentabilidade. O debate é especialmente focado no cenário pesqueiro existente às margens de grandes centros urbanos, como a cidade do Salvador, Bahia onde existe um apelo pelos recursos pesqueiros obtidos pela pesca de pequena escala mercantil. O afastamento social imposto ou recomendado pelo governo têm provocado uma diminuição na procura por pescados oriundos da atividade pesqueira artesanal. Entrevistas semi estruturadas e o livre diálogo com pescadores e marisqueiras atuantes na zona costeira de Salvador permitiu entender o avanço do cenário caótico que já se debruça sobre essa tessitura social. O mercado consumidor, também de pequena escala, desde o âmbito familiar até pequenos comércios como restaurantes e centros de revenda não apresentam mais a dinâmica de busca pelos recursos pesqueiros, interferindo diretamente na oferta devido a concomitante redução no esforço laboral para alimentar essa teia mercadológica. Por outro lado, esses trabalhadores das águas necessitam manter suas atividades a fim de prover fonte de proteína para o seio familiar e comunitário, transitando diretamente pela questão de segurança alimentar da classe pesqueira. Assim como ações para conter o avanço da epidemia do Coronavírus são adotadas pelo governo, contra medidas para salvaguardar o modo de vida dessas comunidades pesqueiras devem ser também pensadas e aplicadas. Seguir as diretrizes da Organização das Nações Unidas para a Alimentação e a Agricultura (FAO) a fim de garantir a pesca de pequena escala sustentável no contexto da segurança alimentar e erradicação da pobreza podem ser os primeiros instrumentos acordados a nível regional para lidar com esse novo cenário de pressão imposto sobre esses comunidades pesqueiras.
The ratio of shear to elastic modulus of in-plane loaded masonry
Authors: Wilding Bastian Valentin , Godio Michele , Beyer Katrin
Published: April 2020

When designing unreinforced masonry buildings, the wall stiffness and, consequently, the masonry elastic and shear modulusEandGare essential parameters. Current codes provide empirical estimates of the masonry elastic modulus and a ratio between the shear and elastic modulus,G/E. This ratio, commonly taken as 0.4, is not based on scientific evidence and there appears to be no consensus concerning its value and influencing parameters, meaning that current code standards might not accurately portray the shear deformations of masonry elements. To give the choice of theG/Eratio a theoretical foundation, this paper presents closed-form expressions for theG/Eratio of running-bond masonry that capture the effects of finite joint thickness, finite wall thickness and orthotropic block properties. Based on the geometry of blocks and joints as well as their elastic parameters, a validation of the developed expression using 3D finite element analyses shows good performance. For modern masonry typologies with hollow clay bricks, aG/Eratio of 0.20–0.25 is obtained. For historical masonry typologies, such as dry stacked or mortared stone masonry, as well as solid clay brick masonry, ratios between 0.30 and 0.40 are computed.
Effect of steel fibres on concrete at different temperatures in terms of shear failure
Authors: Alimrani Naser S. , Balazs Gyorgy L.
Published: April 2020

The behaviour of concrete reinforced with steel fibres at elevated temperatures was investigated in terms of shear deterioration. Using three different steel fibre contents (0, 40 and 80 kg/m3), 45 push-off specimens were tested at five maximum temperatures (20, 150, 300, 500 and 700°C). The main objective of the research was to investigate the effect of steel fibres on the behaviour of concrete at different maximum temperatures in terms of shear failure. The results revealed enhanced ductility and shear strength at elevated temperatures. In addition, the crack widths and crack slips were measured using linear variable differential transducers. It was found that the use of steel fibres increased the shear strength of the concrete at ambient temperature by 103% and 102% for steel fibre contents of 40 and 80 kg/m3, respectively. Although this enhancement was reduced at the high temperatures (500 and 700°C), the mixes containing fibres still had higher residual shear strengths than the plain concrete mix. The steel fibre content also affected the ductility at both ambient and high temperatures.
Construction 4.0 and ISO 19650: a panacea for the digital revolution?
Authors: Winfield May
Published: April 2020

Construction 4.0 is, at its heart, centred around greater digitisation. The ISO 19650 series is the result of 4 years of development and is a game changer in standardising the process of digital information management. It is being actively implemented across the world, from Europe to Australia, but does it progress or hinder the agenda of Construction 4.0 or does it sit outside that movement? This paper provides a critical analysis of the operation of the ISO 19650 series in addressing the legal and contractual impacts of the digitisation of information management. It also considers the related consequences of the legal community’s continuing struggle to understand the consequences and meaning of digital information management and considers how progress can be made in this area.
Cycling-monitoring system: sensing cycling performance via a pedal-integrated inertial measurement unit
Authors: Fudickar Sebastian , Kappes Raphael , Horstmann Marten , Isken Melvin , Hein Andreas
Published: April 2020

With increasing accident rates for elderly cyclists when using electrically powered bicycles, behavioural models for cyclists that consider the underlying functional and cognitive processes are required. Such models must be generated based on experiments conducted in realistic driving conditions, since laboratory studies can cover the complex influences of cycling only to a limited degree. Consequently, this paper introduces a bicycle-monitoring system that was designed to capture all relevant external and internal states to be considered for the conduction of driving behavioural studies in realistic (uncontrolled) environments. Furthermore, algorithms for detecting the turning behaviour and the pedalling frequency by way of a pedal-integrated inertial measurement unit are introduced, and their sensitivity is evaluated in a pilot study.

Aim: To determine the oral health behaviors, the prevalence of dental injuries, the level of information about first-aid procedures in the case of dental avulsion and the mouthguard awareness in a sample of Portuguese athletes. Materials and Methods: Cross-sectional research among 1,048 athletes from the district of Viseu, Portugal. A self-administered questionnaire included demographic data and questions about: I) oral hygiene habits, II) occurrence of orofacial trauma, III) use of mouthguards and IV) athletes’ knowledge regarding first-aid management in case of dental avulsion was given. The comparison between different variables was made by Chi-square test with level of significant set at p-value ≤0.05. Results: The mean age of the sample (76.24% male) was 18.14±8.17 years. Overall, the results demonstrated a low use of dental floss (25.48%) and a high number of athletes (21.94%) that had not visited a dentist in more than a year. The prevalence of dental trauma was 5.06% and the most common dental injuries experienced by athletes were crown fractures (60.38%). Nearly half of the participants (45.23%) reported not knowing how to act following a dental avulsion. The rate of mouthguard use was very low (9.73%). There was a significant relationship between the prevalence of dental injuries and the use of mouthguards (p=0.000; Cramér’s V=0.145). Conclusion: The prevalence of dental trauma in our population was low. A low number of athletes use a mouthguard and there is a lack of knowledge concerning dental trauma issues. Prevention programs and promoting actions among this population are important and should be adopted.

An archaeological experiment focused on the intuitive way of long bones breakage to extract marrow v2
Authors: Vettese Delphine
Published: April 2020

English: This protocol was carried out following a large investigation into the percussion marks distribution on long bones during the extraction of yellow marrow. With these considerations, we carried out an experiment that focusses on the intuitive way to break long bones to recover marrow, involving volunteers without previous experience in this butchering activity. We cross-referenced the data recorded during the breakage process with those from the study of the remains in the laboratory. To do this, the behaviour of the individuals was analysed: the number of blows given, the difficulty felt, the quantity and the quality of marrow recovered, the position of the bone at the time of the blow, the use of the anvil, the grasping of the hammerstone and the position of the individual. Similarly, we took into account various data from the breakage process: the number of remains, the number and type of marks produced and their location. Each novice experimenter had to break a series of 10 bone elements of cow, always the same one. Main questions: Is there a preferential (intuitive) way to break cow long bones of an animal to extract the marrow so that it can be consumed? Does the weight, size or morphology of animal bones influence the appearance of a percussion pattern? French: Ce protocole a été réalisé à la suite d'une large réflexion sur la distribution des marques de percussion sur les os longs lors de l’extraction de la moelle jaune. Dans cette optique, nous avons réalisé une expérimentation qui s’est intéressée à la manière intuitive de fracturer les os pour en extraire la moelle, impliquant des volontaires n’ayant aucune expérience préalable dans cette activité bouchère. Nous avons croisé les données enregistrées lors de la fracturation avec celles issues de l’étude des restes en laboratoire. Pour cela, les comportements des individus ont été décortiqués : le nombre de coups donnés, la difficulté ressentie, la quantité de moelle récoltée, la qualité de la moelle, la position de l’os lors du coup, l’utilisation de l’enclume, la saisie du percuteur et la position de l’individu. De même, nous avons pris en compte diverses données issues de la fracturation : le nombre de restes, le nombre et le type de marques produites et leur localisation. Chaque expérimentateur novice devait fracturer une série de 10 élements osseux de vache, toujours le même élément. Questions principales : Existe-t-il une manière préférentielle (intuitive) de fracturer les os longs d’un animal pour en extraire la moelle de façon à ce qu’elle soit consommable ? Le poids, la taille ou la morphologie des ossements animaux influencent-ils l’apparition d’un modèle de percussion ?

The crisis of employee performance is a critical problem faced by management in the company. Employee performance problems are still widely faced by companies in various sectors in many countries, both engaged in the public and private sectors, in health institutions, education, banking, state-owned companies, to small companies. The low intensity and inaccessibility of work targets due to the low quality of the performance of human resources. Performance is a real behavior that is shown by every employee must be in accordance with his role in the company, that the impact of low employee performance is the quality and quantity of work produced is less satisfactory and the creativity of employees is low. This happened at PT XYZ company where the level of employee performance decreases every year. Surely this is far from the expectations of companies that ask their employees to have good performance. This study discusses research on work discipline and occupational safety health (k3) on employee performance This research uses quantitative methods involving 45 respondents using saturated samples with data collection techniques using questionnaires. The data analysis technique used is descriptive analysis. The results of this study indicate that the picture of work discipline in the high category, the picture of occupational safety and health (k3) in the category is quite high and the description of employee performance in the high category.

Methods have been developed for the preparation of enterosorbents by treating crushed abies bark with the 1.5% aqueous of NaOH solution or by extraction with hexane. It was found that all obtained enterosorbents have good sorption properties with respect to gelatin and methylene blue. The highest sorption activity for methylene blue was shown by a sample, obtained by extraction of abies bark with hexane (97.0 mg/g), and for gelatin sorption activity – a sample, obtained by treatment of abies bark with alkali (225.0 mg/g). It was found that the enterosorbent, obtained by treatment of abies bark with alkali solution both at a dose of 0.15 g per kg of animal weight (g/kg) and at a dose of 0.20 g/kg and the enterosorbent, obtained by extraction of abies bark with hexane at a dose of 0.20 g/kg, have the highest efficiency for the treatment and prevention of acute experimental Escherichiosis. From the considered methods of obtaining enterosorbents from abies bark for the treatment and prevention of gastrointestinal infections of animals, it is recomended to use a method based on treatment of abies bark with alkalai solution and apply the drug in a dose of 0.15 g/kg
Impact of Integrated Technologies of Enhanced Oil Recovery on the Changes in the Composition of Heavy Oil
Authors: Savinykh Yury V. , Chuykina Darya I. , Stakhina Larisa D.
Published: April 2020

This paper deals with the impact of an integrated technology for enhanced oil recovery on the composition of high-viscosity heavy oil produced at the Usinskoye oilfield (Russia, Komi Republic). In order to increase the effectiveness of the thermal-steam stimulation, a surfactant-based composition generating carbon dioxide and an alkaline buffer system is injected into the formation. The analysis of the oil composition is performed via the methods of gradient-displacement liquid adsorption, gas-liquid chromatography, and IR spectroscopy. The results obtained show that two parallel processes are proceeding when pumping an oil-displacing composition. The first process is the additional extraction of residual oil. This process is controlled by an increase in the content of resin-asphaltene substances in oil. The second process is an increase in the coverage of reservoir and the involvement into the development of previously uncovered areas with oil compositionally similar to that at the beginning of development. Using the results of the analysis of the component composition, the individual composition of alkanes, and structural fragments of oil samples in order to control the development of the Usinskoye oilfield, the frontal oil-water boundary advance of the Northern area in the direction of the upper production facility is determined. The obtained patterns of changes in the oil composition after the application of an integrated technology using a surfactant-based composition can be characteristic of other deposits of heavy oil occurring in low-permeability reservoirs

Published: April 2020

The wastewater from leather tanning contains different types of pollutants depending on the internal process that is carried out, in particular, the riparian and tanning stages provide the greatest contaminant load within the process, in terms of organic matter, grease and oils, chlorides, chromium, sulfides among other substances. This study analyzed the efficiency of a biological treatment system, consisting of artificial wetlands of horizontal subsurface flow, in order to evaluate the removal of salinity and organic load present in the water produced during the process of soaking leathers. Two prototypes were tested, one planted with Limonium perezzi and the other unplanted as a control parameter, the wetlands were operated for 32 days. The results show that the planted wetland removes 49.2% of the initial chloride present (44,414.8 mgCl-/L) in the water and 86.2% of the total organic carbon (755.9 mgC/L). It was demonstrated that artificial wetlands are still a viable and efficient alternative in terms of organic load removal, on the other hand, the selected plant showed a very good performance in the treatment of wastewater because of its high tolerance to high concentrations of salt dissolved in the water, reaching perspiration of sodium chloride crystals through the leaves and stem.

Published: April 2020

From its onset on the 1990s, both digital native (with sister headings on the analog platform) as digital native news media have experienced a constant transformation process. The accelerated technological evolution linked to the changing information consumption habits of the users demanded a constant reinvention capability. Furthermore, the need for profit and the drop in advertisement sales have pushed the media to redefine their structure, content and social media presence. The Ibero-American scene has experienced a sprout of a mixture of digital native news media. They are journalistic projects, conceived from and on the Internet, which have reached considerable renown and becoming reference media on the information level. Internet prompted a reduction of the costs related to the creation of media outlets. However, the establishment of a sustainable business model is one of the main challenges. The research presented looks at the business models of Ibero-American digital native news media based on a comparative analysis of 14 case studies, alongside interviews with their founders. The findings include, among other things, a tendency for business models based on diverse and hyper-specialized content targeted at micro-audiences. This research found an interest in horizontality, participation and user engagement, and noticed the need for these media to diversify their income sources.
Data Journalism as a Service: Digital Native Data Journalism Expertise and Product Development
Authors: Appelgren Ester , Lindén Carl-Gustav
Published: April 2020

The combined set of skills needed for producing data journalism (e.g., investigative journalism methods, programming, knowledge in statistics, data management, statistical reporting, and design) challenges the understanding of what competences a journalist needs and the boundaries for the tasks journalists perform. Scholars denote external actors with these types of knowledge as interlopers or actors at the periphery of journalism. In this study, we follow two Swedish digital native data journalism start-ups operating in the Nordics from when they were founded in 2012 to 2019. Although the start-ups have been successful in news journalism over the years and acted as drivers for change in Nordic news innovation, they also have a presence in sectors other than journalism. This qualitative case study, which is based on interviews over time with the start-up founders and a qualitative analysis of blog posts written by the employees at the two start-ups, tells a story of journalists working at the periphery of legacy media, at least temporarily forced to leave journalism behind yet successfully using journalistic thinking outside of journalistic contexts.

Published: April 2020

The conducted researches have the purpose to develop the optimum approach which allows us to correctly estimate the hydrogeological conditions of buiding sites. The general patterns of formation, distribution and movement of groundwater within the sections of the planned and existing buildings and adjacent territories for Kyiv as an example were studied. For the study area and similar sites with complex hydrogeological conditions, which are caused by the alternation in section and in terms of layers of unsteady thickness with different filtration coefficients, it is more appropriate to use the method of mathematical modeling of geofiltration for predictive calculations. Since there is no detailed hydrogeological map of the site, it is advisable to build a natural hydrogeological model on the basis of engineering and geological survey data (groundwater levels data) for different periods reproducted by GIS.

The obtained results make it possible to justify the mathematical model and to perform predictive modeling with sufficient accuracy for technogenically disturbed territories. The application of mathematical modeling allows avoiding unnecessary rough schematization of natural hydrogeological conditions, taking into account the complexity and diversity of boundary groundflow conditions, and thus give more realistic assessment of engineering measures impact on hydrogeological conditions of the territory.

In order to take into account the patterns of formation, distribution and movement of groundwater for territories with dense urban development it is advisable, according to the authors, to simulate processes geofiltration according to the scheme given in this article. At the same time, the creation of scientifically sound mathematical and cartographic space-time natural hydrogeological model of the territory is the defining moment for further modeling. Application of Darcy Flow module of ArcGIS software enables to detect and specificate groundwater flow recharge and discharge conditions. This makes it possible, on the one hand, to avoid unnecessary schematization of natural hydrogeological conditions, and on the other hand, to take into account the complexity and diversity of groundflow boundary conditions, to give a more realistic assessment of possible engineering measures impact on the hydrogeological conditions of the territory during the construction.

A laser Doppler vibrometer was created with the ability to measure the vibrations of distant objects up to 250 meters away. The vibrometer is provided with a scanning system for automatic vibration measurement in an array of points. The control program moves the probe beam according to the research protocol, processes and store information. To demonstrate the capabilities of the system, we studied of the amplitude distribution of vibrations and the distribution of longitudinal stresses in a cantilevered tube located at a distance of 22 meters. The measurements at different frequencies are in good agreement with the numerical calculations performed by finite element code CalculiX.
Childhood autism associated with neurological manifestations and corpus callosum hypoplasia: literature review and clinical cases
Authors: Komissarova O. A. , Milovanova O. A. , Avakyan G. G. , Bugriy S. V.
Published: April 2020

Aim. To consolidate literature data and to demonstrate rare hereditary neurogenetic syndromes with various neuropsychiatric manifestations and a corpus callosum (CC) structurally reduced in size.

Material and methods. Full text data from scholarly journals were used for the review. Mental and neurological disorders were studied in two examined patients with neurogenetic syndromes. A brain MRI showed that it was accompanied with CC hypoplasia. We conducted comprehensive analysis of anamnestic data as well as medical genetic, neurological, psychopathological, pathopsychological, laboratory, and instrumental examinations.

Results. The presented observations testified to a burdened obstetric history, dysfunctional ante-, intra-, and postnatal periods. The first patient with the Wolf-Hirschhorn syndrome was diagnosed with atypical autism associated with severe mental retardation, lack of verbal means of communication, motor stereotypes, structural focal epilepsy, cerebral palsy (CP), severe systemic speech underdevelopment; the second patient with the Prader-Willi syndrome was diagnosed with organic autism associated with mild mental retardation, impaired social adaptation in combination with stereotyped actions, impaired visual-spatial coordination, and cerebral palsy. In the first case, MRI showed posterior CC hypoplasia; in the second case, MRI showed hypoplasia of the CC isthmus.

Conclusion. The level of cognitive deficit was to some extent a value associated with the thickness of the posterior CC. Apparently, a higher degree of myelination of nerve fibers contributes to a higher rate of transmission of nerve impulses along nerve fibers stimulating neurons. The results can be considered preliminary; a larger study is needed.

What Is Our “Epistemic Responsibility”? Reflections on Social Work’s Orientation in Yoga Therapy Research
Authors: Larocque Emmanuelle , Moreau Nicolas
Published: April 2020

The purpose of this article is to explore how the social work discipline could provide a complementary lens through which yoga therapy can be analyzed and evaluated by engaging in knowledge-creation practices and procedures that prioritize the “epistemic responsibility” described by philosopher Lorraine Code. More specifically, by seeking to strategically include often-subjugated types of knowledge and by focusing on redistributing epistemic power to agents that typically have been excluded from epistemic participation in contemporary yoga therapy research, the social work discipline, with its strong commitment to social justice, has the potential to contribute to filling an important gap in scientific literature. We begin by presenting the relevance of the social work perspective in relation to the field of yoga therapy. We next offer a reserved critical analysis of the dominant technical knowledge base that currently informs yoga therapy practice. This analysis highlights the social parameters that may be rendered invisible or left aside when adopting a positivist epistemological lens and justifies how the conceptual apparatus of epistemic responsibility serves as a potential platform for rethinking social work’s position and future contributions to the field of yoga therapy. Finally, we mobilize the concept of cultural appropriation to illustrate how striving for epistemic responsibility provides an entry point for addressing the multilevel, complex social processes embedded in yoga therapy practice and research while aiming to capture the many voices—and hence the various truths—implicated in a democratic, reflexive, and inclusive research process.

Published: April 2020

Having entered into a long-standing discussion about what is leading in the formation of an individual genes or parenting the authors point out the role of the quality of birth as the third equal component of this process. The authors introduced the notion of emergentness in relation to the psychosomatic qualities of a conceived child, distinguishing him from each of the parents and underlying his uniqueness, security and individuality of reactions in the conditions of ambiguity, multifactorial effects (psychological, social, environmental) before and after birth during lifetime.
The effectiveness of the method of external counterpulsation in patients with chronic stable angina
Authors: Alakbarov R H
Published: April 2020

Aim. To assess the effectiveness of the complex treatment of patients with stable angina pectoris using the method of external counterpulsation (ECP).

Methods. 92 patients with chronic stable angina were included in the comparative analysis, which divided into 2 groups: 57 patients received one course of treatment using the ECP method (main group), 35 patients received only drug treatment (control group). Before and after the therapy, a general clinical examination (including determining the functional class of angina pectoris and the need to use nitroglycerin preparations), coronary angiography, echocardiography, exercise stress test (stress ECG), and quality assessment using the Seattle Angina Questionnaire (SAQ) was performed.

Results. The decrease in the average functional class of angina was more significant in the main group compare to the control group from 2.280.73 to 0.930.80 (p 0.05) versus from 2.340.73 to 1.830.71 (p 0.05). A decrease of at least 1 functional class more often occurred in the main group 78.9% of patients versus 57.1% (p=0.0258). The use of nitroglycerin sharply decreased after treatment in the group, that use the ECP method (by 51.6%; p=0.002), whereas in the control group, despite a slight decrease (by 22.7%), the changes did not reach statistical significance (p=0.0736). Both groups showed similar dynamics of changes in echocardiography. The differences were obtained only for the dynamics of the ejection fraction of the left ventricle (LVEF), which was greater in the main group an increase of 4.695.56% versus 1.755.15% (p=0.0448). The dynamics of all indicators of exercise stress test significantly differ between groups, and if for the main group it is positive, in the control group it is negative. Some indicators of quality of life change insignificant and similar for both groups (for example, on the scale for limiting physical exertion), and on some scales (stability scales for attacks and the frequency of angina attacks), the improvement in the main group is much more significant in comparing with the control group: 3037 points versus 1213 points, respectively (p 0.0001). The overall quality of life assessment score improved more in the group, that use the ECP method: +96.1040.73 versus +45.3135.06 the control group (p 0.0001).

Conclusion. The method of external counterpulsation (ECP) can be used in clinical practice as part of a comprehensive treatment of patients with stable angina pectoris; it can significantly reduce the class of angina pectoris and the need to use nitroglycerin preparations, improve a number of indicators of echocardiography, electrocardiography with exercise and quality of life indicators.
