Abstract Background Fractures in stents implanted in the superficial femoral artery (SFA) are recognized complications of endovascular management of this arterial territory. Objectives The objective of this study was to determine the prevalence of fractures in stents implanted in the SFA and to identify predisposing factors for these fractures together with their impact on the patency of these devices. Methods The study included 39 patients (65.7±9.0 years) who previously underwent angioplasty for delivery of 56 stents into the SFA. During follow-up, which ranged from 7 to 46 months, variables were collected on the characteristics of the lesions treated and characteristics of the stents implanted. Two examiners independently analyzed digital radiographs for the presence of stent fractures and the patency of the devices. Results We found a 10.7% prevalence of fracture of implanted stents. Implantation of multiple stents was identified as a significant predisposing factor for fractures. We observed a marked tendency for fractures in female patients and in lesions treated with longer stents (> 150 mm). Stenosis exceeding 50% and occlusions were significantly more frequent in fractured stents. Conclusions This study suggests that implants longer than 150 mm and multiple stents are associated with higher device fracture rates. In cases with stent fractures, stenoses exceeding 50% and occlusions were significantly more frequent.

Resumo O carcinoma anaplásico da tireoide corresponde ao câncer de menor incidência e de pior prognóstico. Neste relato, descrevemos o caso de uma paciente de 64 anos submetida a tireoidectomia total associada a esvaziamento cervical nível VI devido a carcinoma papilífero de tireoide. No seguimento, apresentou sinais de recidiva regional e foi submetida a esvaziamento cervical ampliado e esofagectomia cervical. No intraoperatório, observou-se ausência de plano de clivagem entre o tumor e a artéria carótida comum (ACC) e procedeu-se com implante de shunt carotídeo, resseção em bloco incluindo segmento da ACC e do esôfago acometidos e ponte vascular com interposição da veia safena magna. Foi evidenciado carcinoma anaplásico em revisão de lâmina do exame anatomopatológico. A paciente foi submetida ao tratamento adjuvante e não apresenta sinais de recidiva locorregional. Diante da possibilidade de proceder uma cirurgia curativa com ressecção em bloco, o cirurgião vascular deve estar apto para as opções cirúrgicas.

Published: September 2022

En la investigación en la educación de la física es importante conocer las dificultades de comprensión de temas abstractos. Para desarrollar la comprensión del electromagnetismo, es fundamental que los estudiantes entiendan el concepto de campo. El objetivo del estudio es aportar una metodología que combina la fenomenografía y la teoría de representaciones semióticas para analizar las dificultades de comprensión del campo eléctrico con relación a la conversión de representaciones. Participaron 64 estudiantes universitarios por medio de dos cuestionarios de conversión entre tres representaciones de campo eléctrico: notación algebraica, diagrama de campo vectorial y diagrama de líneas de campo. Se analizaron sus explicaciones combinando el enfoque fenomenográfico y la teoría de representaciones semióticas para crear categorías. Se identificó que las dificultades de reconocimiento se relacionan con la magnitud del campo eléctrico, más que con su dirección. Se encontró un buen reconocimiento en las conversiones entre el diagrama de campo vectorial y la notación algebraica. En las conversiones que involucran líneas de campo, se observaron dificultades de reconocimiento y conversión. Como resultado de este estudio se recomienda que la enseñanza del campo eléctrico se enfoque en el reconocimiento de sus características en cada representación y la conversión entre sus representaciones.

Published: September 2022

Resumo: Nesse trabalho foi realizada uma decomposição espacial do crescimento da Produtividade Total dos Fatores (PTF) do setor agropecuário brasileiro, incluindo componentes diretos (próprios) e indiretos (spillover), no contexto de uma análise de fronteira de produção espacial autorregressiva (SAR) para dados em painel, utilizando os dados censitários de 1995/96, 2006 e 2017 a partir de unidades produtivas referentes a 510 Regiões Geográficas Imediatas (RGI). Os resultados obtidos mostram que o crescimento da PTF foi de 3,87% a.a. na média do período completo, considerando-se apenas os efeitos diretos, e de 6,96% a.a., considerando-se os efeitos totais. Constatou-se também um maior crescimento da PTF no período mais recente e isso está relacionado à expansão da fronteira agrícola para as regiões com baixa produtividade anteriormente. Variáveis como financiamento da agricultura e pecuária, aptidão agrícola, malha rodoviária, plantio direto, correção de solo, escolaridade superior e assistência técnica, mostraram-se estatisticamente significativas na determinação da PTF. Os resultados sugerem que o crescimento da PTF é correlacionado espacialmente e temporalmente, e que spillovers espaciais e seus efeitos locais e globais impactaram a PTF nos três períodos censitários analisados.

Published: September 2022

Resumo: A região do MATOPIBA, formada pelos municípios fronteiriços dos estados do Maranhão (MA), Tocantins (TO), Piauí (PI) e Bahia (BA), é apontada na literatura como a última fronteira agrícola do país, resultante do avanço do agronegócio e do crescimento de um modelo de produção apoiado em alta mecanização. Nesse sentido, o objetivo deste estudo é analisar a situação da modernização agrícola dessa extensão geográfica no ano de 2017. Para isso, as metodologias empregadas consistem na aplicação da Análise Fatorial (AF), Análise Exploratória de Dados Espaciais (AEDE) e na estimação do modelo espacial SAC, tendo como variável dependente o Produto Interno Bruto (PIB) agropecuário e como variáveis independentes os fatores obtidos pela AF. Os resultados encontrados indicaram a presença de sete fatores; e apenas o intensivo em capitalização da atividade agrícola (F1), intensivo em exploração do fator terra (F2) e intensivo em máquinas e implementos agrícolas tradicionais (F3) foram estatisticamente significantes. Portanto, é possível concluir que foi identificada a concentração de alguns fatores em determinadas áreas e que a região precisa de maiores investimentos para que possa se consolidar como uma fronteira agrícola.

Authors: Sousa Filho Jorge Domingos de , Sousa Kayo Henrique Jardel Feitosa , Silva Ítalo Rodolfo , Zeitoune Regina Célia Gollner
Published: September 2022

RESUMO Objetivou-se refletir sobre os sentidos do trabalho da Enfermagem assistencial brasileira no contexto da pandemia da Covid-19. Estudo teórico ancorado na definição de sentidos do trabalho, segundo a perspectiva de Estelle Morin. O trabalho desenvolvido pelos profissionais de Enfermagem ficou ainda mais evidenciado em tempos pandêmicos, vindo à tona as condições precárias dos serviços de saúde no Brasil. Durante a pandemia, a incorporação de sentidos ao trabalho passou a ter importância maior, tendo em vista que a sociedade reconheceu a relevância desses profissionais no enfrentamento da pandemia, e isso possibilitou a discussão acerca do seu reconhecimento social, político e econômico. Os impactos da atuação da Enfermagem durante a pandemia de Covid-19 têm relação com a questão econômica, valores sociais, autonomia no exercício da profissão, reconhecimento e segurança, refletindo na razão de ser do trabalho. Assim, o trabalho que faz sentido para os profissionais de Enfermagem relaciona-se à valorização profissional, especificamente, ao reconhecimento salarial, enquanto o que não faz sentido é aquele que impossibilita avanços do ponto de vista intelectual, cognitivo e financeiro. Dessarte, foram impostas condições que dão rumos para sentidos ambivalentes ao trabalho.

Authors: Pachêco Carla Suzane Góes , Costa Antônio Carlos Silva
Published: September 2022

Abstract: Introduction: Empathy, considered one of the most remarkable characteristics of great medical professionals, is the central element of the doctor-patient relationship and of person-centered care. Objective: To investigate how levels of empathy are manifested in medical students throughout their undergraduate course. Method: This is a quantitative, analytical, observational and cross-sectional study, carried out in a private higher education institution, located in the northeast of Brazil. The research was carried out by applying the Jefferson Scale of Empathy-Student version (JSE-S) and the correlation of the data obtained in the scale with the undergraduate school period and sociodemographic profile of the students, aiming to verify which correlations were significant for the expression of students’ empathy levels, as well as whether there is an erosion during training. Data collection took place between the months of October and November 2020. The study assessed 193 participants, including students attending the first year, an intermediate year and last year of the medical course. The sampling method used was by accessibility and convenience. Results: The global average score of the level of empathy in the group of all study participants (n = 193) was 123.56 ± 11.73. Whereas, by period, it was 124.78 ± 9.85 for first-year students, 124.00 ± 11.87 for intermediate-year students and 120.63 ± 13.57 for last-year students. There was no statistical difference between global scores or by psychometric factor when comparing the three studied groups. As for the correlation of JSE-S with the sociodemographic profile, the variables female gender and reason for choosing the course due to vocation were predictors of higher empathy scores. Conclusion: There was no evidence of empathy erosion regarding the levels of empathy among medical students throughout their undergraduate course, and female students and those who chose the course because they felt they had a vocation for Medicine showed significantly higher levels of empathy. More studies on this topic are essential, considering the importance of a balanced technical-scientific-humanistic posture to enable a medical practice of excellence.

Resumo O Núcleo Ampliado de Saúde da Família e Atenção Básica foi criado no Brasil para apoiar e ampliar a atenção e a gestão na Saúde da Família. Analisa-se a sua atuação quanto à saúde do trabalhador e saúde e ambiente em territórios do campo e das águas com as famílias que vivem da pesca artesanal e da agricultura camponesa. Pesquisa qualitativa que se ancorou em referenciais da Sociologia das Ausências e da Saúde Coletiva, na abordagem particular que esta faz das relações entre saúde, ambiente e trabalho. A pesquisa valeu-se do emprego de grupos focais na produção de narrativas de profissionais do Núcleo Ampliado de Saúde da Família e Atenção Básica em municípios do semiárido e do litoral do Nordeste. Evidenciaram-se singularidades socioeconômicas e culturais das populações do campo e das águas; invisibilidades e potencialidades sobre seus modos de vida e trabalho; cargas e doenças relacionadas ao trabalho; e aspectos da atuação do Núcleo Ampliado de Saúde da Família e Atenção Básica mediante interações com o trabalho e o ambiente nesses territórios. Os cuidados oferecidos a estas populações consideram parcialmente suas especificidades socioculturais, produtivas, ambientais e de saúde, sendo preciso ampliar o reconhecimento de seus modos de vida e trabalho visando intervenções mais exitosas sobre os problemas e necessidades de saúde - o que aponta desafios à formação em saúde para o Sistema Único de Saúde.

Authors: Jesus Luciana Cássia de , Braga Carolina Barbosa dos Santos , Moraes Larissa Galvão , Alves Luciana Mendonça , Reis Vanessa de Oliveira Martins
Published: September 2022

ABSTRACT This study aimed to verify the association between the resources of the family environment and teenage reading. A total of 106 adolescents of both sexes, aged between 11 and 16 years, without learning difficulties, participated in the study. For data collection, a narrative text, a multiple-choice questionnaire about the text and an adapted Family Environment Resources questionnaire were used. Descriptive and inferential analysis was performed using Spearman, Mann-Whitney and Kruskal Wallis correlation tests, with a significance level of 5%. Resources that promote proximal processes and parenting practices contributed to better reading performance. In contrast, the predictable activities category contributed negatively. Thus, the environment and resources influenced the adolescents’ reading performance. It is concluded that the elaboration of school measures and public policies is important to strengthen the family-school relationship, expand family resources and make the environment favorable to teaching.

Published: September 2022

Abstract Introduction: Behavioral therapy (BT) is an association of techniques that aim to minimize or abolish urinary symptoms, including urinary incontinence (UI), through education about the health condition, changes in lifestyle and nutritional habits, and bladder training. Objective: To analyze whether there is a change in the quality of life and severity of UI after group behavioral therapy in women with UI. Methods: Prospective observational study conducted in a pelvic physical therapy public service. Women with UI of any etiology, over 18 years of age, who completed a protocol of four weekly group BT meetings as the first treatment option for UI were included. Outcomes (impact of UI on QoL and classification of UI severity) were assessed before, immediately after, and one month after BT using the King's Health Questionnaire (KHQ) and the Incontinence Severity Index (ISI). Results: Sample of 146 participants. A reduction in the impact of UI on QoL was observed in the KHQ domains: impact of UI, physical limitations, personal relationships, emotions, general health perception (p < 0.05) immediately after BT. After one month, there was a reduction in the UI impact domains, daily activity limitations, physical limitations, general health perception, emotions, and sleep (p < 0.05). In addition, there was a reduction in the classification of UI severity assessed by the ISI (p < 0.001). Conclusion: There was an improvement in QoL and a decrease in UI severity in women with UI who completed a BT group as the first treatment option.
Effect of prehydration of Portland cement on the superplasticizer consumption and the impact on the rheological properties and chemical reaction

Published: September 2022

Abstract The use of pre-hydrated cement in formulation of mortar and concrete is common because there is not always effective control on the cement production, grinding, transportation and subsequent storage. This paper presents a case study on the optimization of admixture for use with prehydrated cement by assessing changes in the rheological properties of Portland cement artificially pre-hydrated. The cement was artificially pre-hydrated by exposure to relative humidity (RHs) of 90%, in an environment of NH4Cl saturated solution. Additionally, the cement pastes were evaluated with and without superplasticizer. Stepped flow test using a parallel-plate geometry was the method choose to evaluate the rheological behavior, apparent viscosity, yield stress and hysteresis area of each paste at the early age. Oscillatory rheometry was conducted to evaluate the storage modulus (G’), comparing the consolidation with the hydration kinetics obtained by calorimetric evaluation of the same suspensions. Initial rheometer results indicate that the pre-hydrated sample presents lower level of shear stress than the reference sample, because of the higher reactivity of the non-pre-hydrated sample.

Abstract Bartonellosis is a vector-borne zoonotic disease with worldwide distribution that infect a broad spectrum of mammalian species. Despite the recent studies carried out in Brazil, information regarding Bartonella in dogs are scarce. Therefore, we performed a retrospective study to investigate the exposure to Bartonella sp. in dogs by indirect immunofluorescence assay (IFA). Three hundred and thirty-five archived serum samples from dogs previously tested for vector-borne pathogens, Toxoplasma gondii, and Neospora caninum were screened for the presence of IgG antibodies to Bartonella sp. All dogs originated from the Metropolitan region of Ribeirão Preto, northeast of the State of São Paulo. Twenty-eight samples (8.3%) were positive for Bartonella sp. at the cut-off of 64. Among the 28 seropositive samples for Bartonella sp., 16 (57.1%) were also seropositive for Ehrlichia canis, 12 (42.8%) for Babesia vogeli, five (17.8%) for T. gondii and three (10.7%) for L. infantum and N. caninum. Our results demonstrated that dogs sampled were exposed to Bartonella sp. Since all the animals sampled in the present study were from private owners, our findings demonstrate that these people may also be exposed to Bartonella sp. Further studies designed to assess whether the infection by other arthropod-borne pathogens such as B. vogeli and E. canis are risk factors for Bartonella infection are needed.

Published: September 2022

Transarterial chemoembolization (TACE) with drug-saturated microspheres is used in the treatment of women with pelvic tumors complicated by bleeding. Another serious problem is peritoneal carcinomatosis. However, it has not been studied whether TACE affects peritoneal lesions, is there a difference in peritoneal lesions with primary and recurrent tumors? The purpose of this article is to analyze the results of TACE in women with peritoneal lesions with primary and recurrent pelvis tumors. This is an analysis of 80 patients with primary tumors (group 1) and 20 patients with recurrent tumors of pelvis (group 2). 8 women in group 1 and 11 women in group 2 had an implantation lesion of peritoneum near the main focus, 3 women in group 1 and 4 women in group 2 had a peritoneum lesion at a distance from the main focus. Angiography revealed differences in blood supply of implantation metastases in the group of primary and recurrent tumors, as well as the blood supply of distant peritoneal metastases. These facts should be taken into account in order to reduce the number of errors in assessing the effectiveness of therapy, to obtain a good clinical result, and to avoid discrediting TACE due to unreasonable requirements for it.
The object of public control (supervision) as an element of democratic civil control
Authors:   Lviv State University of Internal Affairs, Shopina І.
Published: September 2022

The purpose of the article is to define the concept and features of the object of public control (supervision) as an element of democratic civil control. The rationale is given that the emergence of democratic civilian control over the security and defense sector was due to the growth of social responsibility of members of society for the state of affairs in the state, combined with the development of mechanisms for ensuring human and civil rights. Attention is focused on the fact that the activity of public control (supervision) in the security and defense sector is constantly increasing, which makes it possible to predict the achievement of greater order and structure by this type of public activity. The article determines that the understanding of the object of control in domestic legal science traditionally covers three main approaches. According to the first of them, the object is a set of bodies and officials who are entrusted with the obligation to carry out a set of actions related to their openness and the need to report to other entities for which they are controlled. The second approach is associated with the recognition of the object of control of the activities or behavior of certain bodies or officials. The third approach, much broader in content, suggests that the object of control is more abstract categories – public goods. The concept is formulated as an object of public control (supervision) as an element of democratic civil control. The definition is proposed: the object of public control (supervision) is a set of public goods of a non-patronage nature, arising from the activity of members of civil society and consisting in the protection of the rights, freedoms and interests of individuals and legal entities, reducing the level of corruption risks and the effective rational use of budgetary funds in the security sector and defense. The article substantiates that the non-patronage nature of public control (supervision) means that the source of benefits is not the state, but civil society. The argument is given that public control (supervision) extends to the protection of the rights, freedoms and interests of not only civilians, but military personnel. The article determines that the subject of public control (supervision) is that part of the object that can be of a specific nature and can be analyzed, measured, compared, etc.

The article identifies the role of public sector accountants in creating value for the state and society and suggests ways to improve skills in making professional judgments. Public accountants should provide the necessary information for decisionmaking and check the current activities of public organizations. The accountant of the public sector institution informs the population and allows assessing the efficiency and cost-effectiveness of the institutions that provide public services. Thus, for an accountant working in public administration, it is essential to provide information primarily to meet the information needs of citizens, NGOs, and society in general, to determine the cost of maintaining these bodies – how much taxpayers work for civil servants. At the same time, despite the existing problems and troubles, the accountant profession is constantly evolving in response to the constant development of socio-economic relations, the introduction of new innovative technologies, and the integration of society, which leads to growth, and organization in solving problems and advocating. Despite this key role of accounting in the public sector, it is underestimated compared to scientific and professional accounting in the corporate sector. The role of higher education institutions is to provide students with the skills necessary not only to enter the profession but also to solve environmental, economic, and social problems. The role of professional accounting organizations is to develop the profession as a whole – both in the private and public sectors. The factors of unfavorable influence on the development of the accounting profession in the public sector are identified, and directions for increasing its prestige are proposed. The acquisition of new knowledge and practical skills and the identification of barriers to the acquisition of relevant skills in accordance with international best practices and standards contribute to the role of accountants in the public sector and increase their social value, especially in the context of international practices.

Authors:   Baku State University, Baku, Azerbaijan, Piriyev R.
Published: September 2022

The Caspian Sea is the largest closed reservoir in the world. The strongest earthquake in the Caspian Sea was the 7.9 magnitude, the 1895 Krasnovodsk earthquake. The parameters of earthquakes with different magnitude in recent years in the Caspian Sea were analyzed and the characteristic depth was determined based on statistical data. Attempts to determine their periodicity and attempts to predict for the future have been made on the basis of statistical data of earthquakes occurred within the last 50 years in the Caspian Sea and surrounding regions. In the data taken from the earthquake catalog, parameters of earthquakes whose magnitude is above 5.0 were used. In recent years, earthquakes with a magnitude below 5.0 have been accompanied in the Caspian Sea. The characteristic depth of earthquakes is considered ±60 km. The probability of recurrence of an earthquake with a magnitude of 6.8 occurred in 2000 is likely to occur in 2050.
PROSPECTS OF INDUSTRIAL ORE-BEARING OF ZHYRYCHI ORE OCCURRENCE

Based on the analysis of geological exploration materials, geological and economic reassessment of the copper ore occurrence in Zhyrychi (Volyn ore region) was carried out, including the recalculation of reserves and unproved resources. As it turned out, during the exploration process, the reserves and unproved resources were significantly exaggerated, which misleads potential investors. This was primarily due to the wrong interpretation of the geological structure of the deposit, shape and size of ore bodies. The considerable horizontal length of ore bodies, which at a thickness of 1–3 m extend for several kilometers (up to 4–5 km), raises great doubts. In our view, they are represented mainly by lenticular bodies of relatively short length (the first tens up to the first hundreds of meters). According to our calculations, the unproved resources of copper of category P1 are 220.4 thousand tons, which is four times smaller than in the relevant exploration materials. Reserves of copper of category C2 and the unproved resources of precious metals should be excluded from the calculation as unreasonable and unreliable.

The area of the Pologivskiy deposit of kaolins and refractory clays is located on the border of two geological regions: the Azov crystalline massif and the Konksko-Yalynska depression. Precambrian crystalline rocks and sediments of the Cretaceous, Paleogene, Neogene, and Quaternary systems take part in the geological structure of the district. The geological structure of the district is based on the results of field exploration (23–25) and geological surveying works. Deposits of the Quaternary system are widespread in the territory and are similar to mantle on the underlying rocks. The lower border of the Quaternary system is formed at the base of the Berezanskiy climatolite in accordance with the Geological Map of Ukraine legend (the scale 1:200 000) of the 1996 Central Ukrainian series. The underlying rocks are red-brown Pliocene clays in most parts of the territory, in the rest there are rocks of crystalline basement of Cretaceous, Paleogene and Neogene systems. The thickness of the Quaternary deposits is 10–20 m. Deposits of the Novopetrivska Neogene suite are productive for the extraction of clays and kaolins, in the base of which the undivided deposits of the Upper Eocene (Kyivska suite) and Oligocene (Kharkivska suite) lie. These are coastal-marine deposits – marls, calcareous clays, siltstones, weakly cemented sandstones and glauconite quartz sands. The total thickness of the Kyivska and Kharkivska suites varies from 0,0 to 60–70 m. Clays and kaolins are characterized by almost the same mineral composition. Most of them are composed of fine-grained kaolinite, and quartz predominates among impurities. Accessory and ore minerals are represented by zircon, rutile, ilmenite and hematite. Quartz is present in clays and kaolins in the form of rolled, semirolled and unrolled grains. High-quality aluminosilicate products are obtained from the kaolins of the deposit. Pologivskiy kaolin can be used to make chamotte without the clay addition, as well as a binder. The ratio of chamotte and binder is 80–20 %. The refractories obtained in the laboratory meet the requirements of high density for Class A blast furnace bricks and other products of appropriate determination. Pologivskiy clays are recognized as suitable for the production of 100 % refractories, as well as a binder component instead of ChasovYarska clays. Products made entirely of semi-acid clay meet the requirements for semi-acid refractory products of class B. Pologivskiy kaolins and clays have long been used in refractory, machine-building, ceramic, cement and other industries.

Published: September 2022

The issues of TCAD simulation of low-voltage logic gates made on SOI CMOS nanotransistors with cylindrical geometry with a fully enclosing gate with a variable diameter of the working area are discussed. Changing the geometry of the working area compared to the usual cylindrical shape improves the electrophysical characteristics and allows you to compensate for the limitations that arise as a result of scaling. Numerical studies of conical prototypes were carried out using mathematical simulation performed using the TCAD instrument technological simulation program based on the n- and p-type nanotransistor models developed by TCAD. The simulation results demonstrate improved electrostatic characteristics. The conical structure in the control voltage range from 0 to 0.6 V is characterized by a higher transistor current, a maximum Ion/Ioff current ratio, a low leakage current and a slope of the subthreshold characteristic close to the theoretical chapel. The dynamic characteristics of the developed physical models of the inverter and the chain of 11 inverters are numerically investigated for the optimized ratio of the diameters of the working area of 8.1/10 nm and the gate length of 25 nm. At control voltages of 0.6 V and a frequency of 25 GHz, the inverter model predicts a maximum switching delay of 1.5 ps, the limit level of active power of 0.21 μW, static 4.4 pW. The active power consumed by the circuit consisting of 11 inverters is 2.34 μW at control voltages of 0.6 V.

The paper presents the results of experimental studies of the heating dynamics of metal-dielectric structures (MDS) with aluminum conductive nanoscale films deposited by magnetron sputtering on low-cost substrates (glass, sitall, PET and PTFE) under exposure to monochromatic ultrahigh frequency (UHF) fields in a waveguide. At film thicknesses less than 2 nm, the experimental samples had mostly dielectric properties. Noticeable interaction of the films with microwave, causing thermal phenomena, was observed at thicknesses greater than 2 nm and reached a maximum at 5 nm. Thermal degradation processes of the metallized layer manifested in different ways in MDS with solid and polymer (flexible) substrates. Breakdown in conductive films generally occurred at temperatures below the melting temperature of the film material and occurred perpendicular to the electric field strength vector.

Published: September 2022

Existing problems of routing algorithms, such as high overhead costs for scaling components and low fault tolerance of the system, are considered. An algorithm is proposed that eliminates the shortcomings of the existing ones due to the rejection of a centralized router and the strict separation of pipelines within the system. The algorithm is based on adding a special token to the message. For the proposed algorithm, the performance improvement is mathematically proved, and the practical load on the system is simulated to confirm the obtained theoretical results.

Methods of non-orthogonal multiple access are a promising group of techniques that allow increasing the noise immunity of communication and the number of network connections. One of the implementation techniques of this approach is sparse code multiple access (SCMA). The use of SCMA in conjunction with multiple-input multiple-output (MIMO) systems allows for a high level of noise immunity and spectral efficiency and can be a concept for organizing the physical layer of 6G networks. In this article we look at different MIMO-SCMA circuits and give the basic steps of signal formation and processing. One of the problems in implementing SCMA-MIMO is the high computational complexity of signal processing algorithms in the receiver. To solve this problem, we suggest using a method based on QR-decomposition. In the article, we demonstrate that this method makes it possible not only to reduce computational complexity by several times but also to provide higher noise immunity compared to classical approaches. The results are obtained for various MIMO configurations and modes. The proposed method can be used in promising communication systems of future generations.

Objective: аssessment of orlistat, liraglutide and sibutramine consumption in the Russian Federation as drugs recommended by the Russian clinical guidelines for the pharmacotherapy of obesity.

Material and methods. From IQVIA database, the information was selected on retail sales and procurement of the specified drugs at the expense of the federal and regional budgets in the period of 2011–2021. The consumed volumes of each drug were recalculated into the number of defined daily doses (DDDs) for each international nonproprietary name in accordance with the World Health Organization methodology.

Results. It was demonstrated that over a 10-year period there was a tendency to reduce the consumption of drugs for the treatment of obesity from 83.03 million DDDs in 2011 to 71.7 million in 2021. Sibutramine consumption dominated throughout the observation period: its share ranged from 76% to 84%. The proportion of people receiving obesity pharmacotherapy in the Russian Federation was about 0.5%. Herewith 58–66% of DDDs sales took place in 3 regions: Moscow, Moscow Region and Saint Petersburg.

Conclusion. Low efficacy, high frequency of adverse effects, frequent weight gain after therapy termination, as well as low orientation of doctors to the need for pharmacotherapy are probably the main factors determining the low prevalence of using drugs for the treatment of obesity in Russia.
Orientación ideológica y función política de la educación en la historia constitucional española
Authors: Capodiferro Cubero Daniel
Published: September 2022

Este artículo repasa las distintas normas sobre educación que, desde principios del siglo XIX, y en paralelo a la historia constitucional española, han establecido su orientación o condicionamiento ideológico y, con ello, han definido cómo era la integración de los sujetos en los sistemas políticos que se han ido sucediendo. Algo que casi siempre se ha planteado con una intención eminentemente defensiva de la situación definida desde el poder, con independencia de que se tratara de un sistema democrático o autoritario, hasta llegar a la Constitución vigente, cuya previsión al respecto establece una clara diferencia en lo que respecta al ideario educativo.
