Nanocomposites based on biomolecules and highly dispersed silica are quite promising for use in many fields of biotechnology. There are many methods of obtaining such materials, in particular, adsorption from liquid or gas phases. Saccharides and their derivatives are present in the human body, they are involved in metabolic process, thus it is reasonable to use them while working with biomolecules. The work considers such disaccharides as sucrose, lactose and N-acetylneuraminic acid (NANA). Being a part of glycoproteins and glycolipids, NANA is also considered to be a carbohydrate. The main objective of the study was to study the ways of interaction of NANA on the disaccharide-modified silica surface. The methods of quantum chemistry have been used to find the probable structures of three-component adsorbtion complexes at molecular level and to clarify the mutual influence of these compounds in adsorbtion process. An analysis of the results of quantum chemical calculations shows that the adsorption of an anion of N-acetylneuraminic acid on silica surface is less likely than in its molecular form. Molecules of N-acetylneuraminic acid, disaccharides and silica form intermolecular complexes due to intermolecular hydrogen bonds between polar functional (mainly –OH) groups of the analytes. The sucrose dimer is 85.4 kJ/mol stronger than the lactose one. The sucrose molecule also forms a 38.1 kJ/mol stronger intermolecular complex with the N-acetylneuraminic acid molecule compared to a similar complex where lactose is used as a disaccharide. The highest energy (245.2 kJ/mol) is released when a silica cluster interacts with the intermolecular complex of N-acetylneuraminic acid and sucrose provided silica and the sucrose molecule are in a direct contact with each other. Therefore, as studies have shown, the adsorption of N-acetylneuraminic acid is possible if silica surface is pre-modified with disaccharides. The results of quantum chemical modeling confirm the obtained experimental data.

The experimental results obtained in the study on the possibility of sensitizing titanium dioxide (polymorphic anatase phase) to the visible region of the spectrum by doping and co-doping with impurities of non-metals in order to create effective photocatalysts for the decomposition of organic compounds have been analyzed. The presence of impurity atoms appears to result in a change in the electronic structure of the titanium dioxide matrix, in the appearance of “impurity bands” and in the narrowing of the energy gap of titanium dioxide. Such a modification is accompanied by an extension of the spectral range of sensitivity of photoactive solids to the long-wavelength region of the spectrum and, therefore, can be used to improve the catalytic properties of these materials. Spectral manifestations of carbon impurities in titanium dioxide in the form of carbide and carbonate, as well as sulfur in the forms of sulfite, sulfide, and sulfate, have been studied by the density functional theory method. A Ti14H22O39 cluster model was chosen for the titanium dioxide matrix. The calculations were carried out in the framework of the cluster approximation, using functional B3LYP and basis set 6-31G (d, p). Comparison of the results of quantum chemical calculations with the available experimental data shows that the impurity sulfur and carbon atoms in titanium dioxide, which are in different coordination states and different oxidation states, appear in different spectral ranges. This circumstance makes it possible to elucidate the structure of the samples based on the experimental spectra. A change in the coordination and oxidation states of impurity atoms leads to spectral shifts and splitting of peaks, which can reach 1.5 eV (XPS). The presence of admixtures of non-metals leads to a change in color (deepening in the case of sulfide or carbide) of the samples, appearing in the corresponding UV spectra.

The adaptive capabilities of a parallel version of a multipopulation genetic algorithm are considered depending on the characteristics of certain classes of fitness-functions. Ways are proposed to increase the rate of convergence to the optimal solution based on effective control of algorithm parameters and strategies for the exchange of chromosome-solutions between populations. The results of computer experiments with the optimization of fitness-functions with various ratios of insignificant and significant factors are presented. The dependence of the convergence rate of the algorithm in the presence of a random effect on the values of fitness-functions is studied.
ELECTROMAGNETIC EFFECTS OF ACOUSTIC AND ATMOSPHERIC GRAVITY WAVES IN THE NEAR-EARTH ATMOSPHERE
Authors:   V. N. Karazin Kharkiv National University, Luo Y. , Chernogor L. F. ,   V. N. Karazin Kharkiv National University
Published: December 2020

Purpose: Acoustic and atmospheric gravity waves (AAGW) are generated by many natural and anthropogenic sources. The AAGW propagation at ionospheric heights is accompanied by the generation of disturbances in the magnetic and electric fields. The plasma presence plays a crucial role. The mechanisms for generating electrical and magnetic disturbances in the near-Earth atmosphere by the AAGW have been studied much worse. Therefore, the validation of the capability to generate electromagnetic disturbances in the near-Earth atmosphere by the AAGW is an urgent problem. The purpose of this paper is to describe the mechanism for generating disturbances in the electric and magnetic fields in the near-Earth atmosphere under the action of AAGW and to estimate the amplitudes of these disturbances for various AAGW sources. Design/methodology/approach: The impact of a series of highenergy sources often results in the generation of synchronous disturbances in the acoustic and geoelectric (atmospheric) fields, when an approximate proportionality between the pressure amplitude and the amplitude of the disturbances in the atmospheric electric field is observed to occur. Based on the observational data and making use of the Maxwell equations, the theoretical estimates of the disturbances in the electric and magnetic fields have been obtained. Findings: Simplified expressions have been obtained for estimating the amplitudes of the electric and magnetic fields under the action of the AAGW generated by natural and manmade sources. The amplitudes of the electric and magnetic fields generated by the AAGW of natural and manmade origin, which travel in the near-Earth atmosphere, have been calculated. The amplitudes of the AAGW generated electric and magnetic fields are shown to be large enough to be detected with the existing electrometers and fluxmeter magnetometers. The magnitudes of the amplitudes of the electric and magnetic fields generated in the near-Earth atmosphere under the action of AAGW are large enough to trigger coupling between the subsystems in the Earth–atmosphere–ionosphere–magnetosphere system. Conclusions: The estimates and not numerous observations are in good agreement. Key words: acoustic and atmospheric gravity waves, near-Earth atmosphere, volume charge, atmospheric pressure disturbances, electric field, magnetic field

Algunas interpretaciones teológicas de Amoris laetitia han vuelto a considerar separadamente elementos de la estructura de la acción que impiden una comprensión correcta de la moralidad de algunas acciones consideradas de particular complejidad. El artículo revisa la naturaleza de la llamada del Papa al discernimiento en su perspectiva específicamente moral que en algunas lecturas han discurrido en la dirección del juicio y la estructura de la acción prudencial. De entre estas, se presenta finalmente la propuesta de una perspectiva de análisis moral que permita una consideración unitaria de la acción y del sujeto agente en el proceso afectivo e intencional de la generación de la acción.
Unified Speech-Like Interference for Active Protection of Speech Information
Authors: Avdeev Vladimir , Trushin Viktor , Kungurov Mihail
Published: December 2020

The paper considers the possibility of creating a speech-like interference for the means of vibro-acoustic protection of speech information based on tables of syllables and words of the Russian language. The choice of research directions and experimental conditions is substantiated: synthesis of sound files by random sampling of speech elements from a database, research of spectra of synthesized noise, algorithm for creating interference of the “speech choir” type, study of autocorrelation functions of synthesized speech-like interference, as well as their probability distribution density. It is shown that the spectral and statistical characteristics of the synthesized speech-like interference type "speech choir" of five voices are close to similar characteristics of real speech signals. At the same time, the speech choir was formed by averaging the instantaneous values of temporary realizations of sound files. It is shown that the spectral power density of the speech-like interference of the “speech choir” type practically is not changed with the number of averaged “voices” starting from five. The probability density distribution of the speech-like interference value with an increase in the number of voices in the “speech choir” approaches the normal law (unlike a real speech signal whose probability density is close to the Laplace distribution). Evaluation of the autocorrelation function gave a correlation interval of several milliseconds. The articulation tests of speech intelligibility using synthesized speech-like interference with different signal-to-noise ratios showed the possibility of reducing the integral noise level by 12-15 dB compared to noise-like interference. The dependencies of verbal intelligibility on the integral signal-to-noise ratio are constructed on the basis of polynomial and piecewise linear approximations. A preliminary assessment of a possible impact of speech-like interference on the psycho-emotional state of a person was performed. The direction of further research on increasing the efficiency of algorithms for generating speech-like interference is discussed.

Published: December 2020

The main factors that determine the expansion of capabilities and increase the effectiveness of network intelligence to identify the composition and structure of client-server computer networks due to the stationarity of their structural and functional characteristics are analyzed. The substantiation of an urgent problem of dynamic management of structurally-functional characteristics of the client-server computer networks functioning in the conditions of network reconnaissance is resulted on the grounds of the revealed protection features of client-server computer networks at the present stage that is based on realization of principles of spatial safety maintenance, and also formalization and introduction of forbidding regulations.

The mathematical model allowing to find optimum modes for dynamic configuration of structurally-functional characteristics of client-server computer networks for various situations is presented. Calculation results are given. An algorithm is presented that makes it possible to solve the problem of dynamic configuration of the structural and functional characteristics of a client-server computer network, which reduces the reliability time of data obtained by network intelligence. The results of practical tests of software developed on the basis of the dynamic configuration algorithm of client-server computer networks are shown. The obtained results show that the use of the presented solution for the dynamic configuration of client-server computer networks allows to increase the effectiveness of protection by changing the structural and functional characteristics of client-server computer networks within several subnets without breaking critical connections through time intervals that are adaptively changed depending on the functioning conditions and the attacker’s actions.

The novelty of the developed model lies in the application of the mathematical apparatus of the Markov’s theory of random processes and Kolmogorov’s solution of equations to justify the choice of dynamic configuration modes for the structural and functional characteristics of client-server computer networks. The novelty of the developed algorithm is the use of a dynamic configuration model for the structural and functional characteristics of client-server computer networks for the dynamic control of the structural and functional characteristics of a client-server computer network in network intelligence.

Published: December 2020

The effects of nitrogen fertilization (NF, 60-100 kg ha-1) and parboiling operation (soaking temperature (SoT, 50-80°C) and steaming time (StT, 10-15 min)) on the protein content (PC), amylose content (AC), gelatinization temperature (GT), hardness value (HV), peak viscosity (PV), trough viscosity (TV), final viscosity (FV), breakdown (BD), setback (SB) point, peak time (PTi), and pasting temperature (PTe) of brown rice were evaluated. Results showed that the GT, HV, FV, and TV were significantly increased by increasing the NF, SoT, and StT levels. An increase in the SoT and StT levels led to a significant reduction in PC, AC, BD, and TV values. The AC (17.13-16.83%) and PV (1605-1588 cP) values were decreased by increasing the NF level, while the PC (8.78-9.46%) and BD (226.9-247.7 cP) values were increased. Rheological parameters of BD (336.4 cP), FV (3608.5 cP), and SB (1843.5 cP) were notably increased using the combined treatment of 100 kg ha-1 NF and of 80°C SoT. The best triple treatments for the improved GT (5.0 °C), HV (19.37 N), as well as FV (3923 cP), and SB (1949 cP) were 60 kg ha-1 NF+80°C SoT+15 min StT, 100 kg ha-1 NF+80°C SoT+15 min StT, and 100 kg ha-1 NF+80°C SoT+10 min StT, respectively.

Published: December 2020

The electrocardiogram (ECG) is a graphical recording of the cardiac electric activity during cardiac revolutions. This bio-current triggers and maintains the mechanical activity of the heart. Within this research, the amplitudes values of the electrocardiographic waves were determined in 6 leads: I, II, III, aVL, aVR and aVF. Thus, some electrocardiograms were recorded using limb lead in clinically healthy kids, aged 1 month, 3 months and 5 months, in order to achieve the proposed objectives. Then, the statistical analysis of the obtained results was performed using t (student) test.As a consequence of the interpretation of the obtained results, it was noticed that the limb leads can be used successfully for recording the electrocardiogram in kids because it provides an easy aspect to interpret. The highest amplitude of the electrocardiographic waves is recorded in I lead, in the case of the 1 month old kids (having the following values: 0.115 mV ± 0.010 for P wave; 0.625 mV ± 0.078 for QRS complex; 0.460 mV ± 0.045 for T wave) and in II lead (having the following values for the 3 months old kids: 0.071 mV ± 0.015 for P wave; 0.540 mV ± 0.064 for QRS complex; 0.310 mV ± 0.052 for T wave and having the following values for the 5 months old kids: 0.071 mV ± 0.015 for P wave; 0.455 mV ± 0.028 for QRS complex; 0.430 mV ± 0.026 for T wave). It also found that the lowest amplitude of electrocardiographic waves is recorded in the aVF lead, but this lead cannot be used for ECG recording in kids.

Published: December 2020

The article reveals the problem of defining technological competence, analyzes various approaches to the concept of technological competence from the standpoint of personality quality, specificity of activity, or a personal-activity approach to learning. The scientific work reflects fundamental research on the problems of the competence approach in education and technological competence of V.I. Zagvyazinsky, V.V. Kraevsky, V.M. Polonsky, M.N. Skatkina, E.F. Zeera,
A.V. Khutorsky, L.S. Vygotsky, A.N. Leontiev and others. The authors also analyzed scientific works on the problem of technological competence among young researchers such as S.M. Markova,
V.V. Borisov, S.Yu. Yagupets, E.I. Nikiforova, N.N. Shumilkin, Ya.V. Chub, showing a versatile attitude to this concept. The feasibility of a complete constructive and correct definition of the concept of "technological competence" is due to the presence of unsettled definitions in science, that is, researchers often use different terms to denote the same phenomenon, or use the same term to designate different concepts, and do not reflect the methodological essence of technological activities. In addition, there was a lack of clarity, mixing or substitution of the concepts of "technological competence" and "technical competence", "technology" and "technique", "technological means" and "technical means". The presented material allows us to consider technological competence as an integral component of professional competence from the standpoint of the personality-activity approach, taking into account the personality characteristics and the specifics of technological activity, as generalized for all areas.

Resumo Investigamos o desenvolvimento da relação coparental e conjugal durante o processo de transição para a parentalidade no contexto da reprodução assistida, a partir de um estudo de caso coletivo longitudinal. Realizamos uma análise narrativa das entrevistas respondidas por três casais na gestação, no terceiro mês do bebê e em seu primeiro ano. Quando um dos cônjuges já tem filhos pode haver uma assimetria no enfrentamento do tratamento e da transição para a parentalidade. Pode haver, ainda, um deslocamento dos temas de conflito, embora estes tendam a ser abordados com as mesmas estratégias presentes na história do casal. Identificamos indícios da coparentalidade já no tratamento, havendo uma diferenciação crescente entre conjugalidade e coparentalidade.

Published: December 2020

Resumo Esse artigo discute como a luta indígena do povo Mbya Guarani pode ser compreendida como uma dimensão necessária para o estudo da promoção de saúde; luta que se dá em uma situação em que as comunidades manifestam a vivência de uma série de conflitos denunciados, como desrespeito do Estado brasileiro aos seus direitos constitucionais. Realizamos uma análise dialógica de discursos de lideranças Mbya Guarani, presentes em noticiários produzidos por coletivos indígenas e no documentário “Teko Rexaĩ: Saúde Guarani Mbyá”. Discutimos as tensões entre a concepção Guarani de Teko Porã e o que está previsto pelo Subsistema de Atenção à Saúde Indígena. Argumentamos que as concepções de saúde e de cuidado, desde o enfoque do construtivismo semiótico-cultural em psicologia e suas interfaces com a reflexão ética, devem considerar o ethos indígena. Isso permite repensar o papel dos agentes de saúde em relação aos problemas relatados pelas lideranças indígenas.

SUMMARY INTRODUCTION: There are several reports worldwide about the high mortality related to COVID-19 among residents of nursing homes. The worldwide concern about the safety of patients and professionals in these institutions is relevant. In Brasil, a large part of post-acute care and chronic patients is performed at home through Home Care (HC). OBJECTIVE: This study aims to evaluate the incidence of COVID-19 in Home Care patients and the clinical outcomes of these patients; it also aims to assess the impact of the epidemic on the number of patients, new admissions, and hospitalizations. METHODS: A descriptive study of the COVID-19 cases that affected the population in care by Home Doctor (a private company of Home Care), between the months of March 2020 and May 2020 and analysis of the total number of patients, the hospitalization and death rate in the period compared to the pre-epidemic period. RESULTS: There were 31 confirmed cases of COVID-19, 21 of which were male, mean age 73 years. All patients had multiple comorbidities, the most prevalent were: Systemic Arterial Hypertension (54%) and Stroke (35%). The incidence of COVID-19 was 1% in the studied population. There were 10 hospitalizations with 5 hospital deaths and one case of home death (lethality 19%). Safe care was maintained, with a low death rate (0.6%) and hospitalization (6.1%). CONCLUSION: Home Care is able to maintain safe care during the pandemic due to COVID-19, with a low incidence of COVID-19, low hospitalization rate, and low mortality when compared to nursing homes institutions.

SUMMARY BACKGROUND: The aim of this study is to evaluate the peptidylarginine deiminase 4 (PAD 4) concentration and PADI4 polymorphisms as predictors of acute kidney injury (AKI) development, the need for renal replacement therapy (RRT), and mortality in patients with septic shock. METHODS: We included all individuals aged ≥ 18 years, with a diagnosis of septic shock at ICU admission. Blood samples were taken within the first 24 hours of the patient's admission to determine serum PAD4 concentration and its PADI4 polymorphism (rs11203367) and (rs874881). Patients were monitored during their ICU stay and the development of SAKI was evaluated. Among the patients in whom SAKI developed, mortality and the need for RRT were also evaluated. RESULTS: There were 99 patients, 51.5% of whom developed SAKI and of these, 21.5% needed RRT and 80% died in the ICU. There was no difference between PAD4 concentration (p = 0.116) and its polymorphisms rs11203367 (p = 0.910) and rs874881 (p = 0.769) in patients in whom SAKI did or did not develop. However, PAD4 had a positive correlation with plasma urea concentration (r = 0.269 and p = 0.007) and creatinine (r = 0.284 and p = 0.004). The PAD4 concentration and PADI4 polymorphisms were also not associated with RRT and with mortality in patients with SAKI. CONCLUSION: PAD4 concentration and its polymorphisms were not associated with SAKI development, the need for RRT, or mortality in patients with septic shock. However, PAD4 concentrations were associated with creatinine and urea levels in these patients.

Published: December 2020

SUMMARY BACKGROUND: Asymmetric or heteropagus conjoined twins is a rare occurrence, with an incidence of one case in 1-2 million. Conjoined twins are classified according to their symmetry, place of fusion, and grade of duplication. METHODS: We report here an extremely rare presentation of parasitic twins not described before. We describe macro and micro anatomic alterations and discuss the aspects of this peculiar presentation and the importance of prenatal diagnosis. RESULTS: The case of a twenty-three-year-old patient, with monochorionic, monoamniotic asymmetrically-conjoined twin pregnancy, discovered at 29 weeks of gestational age. We believe that this report calls attention to this presentation and the importance of prenatal care and management. The twins were delivered vaginally without life. The twins’ combined weight was 1.300 gr. They were bonded in the left cervical region. CONCLUSION: This report may help to find strategies for clinical decisions in future cases. Antepartum diagnosis is important to the management, preoperative planning, and outcomes. Prenatal imaging exams like echocardiography, CT, MRI, and ultrasonography are feasible and can provide relevant information about malformation severity and prognosis.

SUMMARY INTRODUCTION: In the future, surgery will be centralized in hospitals with the best value (excellent results with reduced cost). High-performance teams will be required; however, available data concerning the specific abilities necessary to build and manage them are poor. OBJECTIVES: Share the set of competencies and skills established to build and lead a high-performance general surgery team. METHODS: In November 2012, a general surgery team started its activities at a tertiary hospital in Sao Paulo, Brasil. The model consisted of high volume performed by a small team. Experienced surgeons, motivated, and with technical and moral excellence were selected. A sense of unity was created and goals were shared. Complex cases were discussed daily and a prospective database to follow outcomes was established. The payment value was above the market. RESULTS: In 6 years and 4 months, 11,006 surgical procedures were performed (8,597 electives and 2,409 in an urgent setting). Cholecystectomy was the most common procedure (4,101; being 3,676 electives), followed by inguinal hernioplasty (n: 1,827) and appendectomy (n: 925). A total of 449 elective oncologic procedures were performed. The surgical site infection rate in clean procedures was 0.12%, 80 patients required re-do surgery (2.4% in an urgent setting and 0.2% of the electives). There were 22 postoperative deaths (0.66% for urgent and 0.07% for electives), 5 of the 6 deaths in elective patients were in oncologic cases. CONCLUSION: A competent surgical team, inserted in a model that favors performance and values the individual can deliver high volume with exceptional results.

SUMMARY BACKGROUND: This study aimed to investigate the deletion polymorphisms of the genes of the glutathione S-transferase family GSTT1 and GSTM1 in patients with Polycystic Ovarian Syndrome (PCOS), comparing them with a control population. METHODS: Blood was collected from 219 women (110 with PCOS and 109 controls) and genomic DNA was extracted. For the analysis of polymorphisms, the technique used was multiplex PCR. In the statistical analysis, the chi-square test and multiple logistic regression were used. RESULTS: There is no association between the GSTM1 null and GSTT1 null genotypes with PCOS when analyzed separately (P = 0.616 and P = 0.188). The analysis of the combined genotypes showed differences between the groups (P < 0.05), evidencing that the genotypic combination GSTT1 positive and GSTM1 negative is more frequent among patients. In the multivariate analysis, smoking was more frequent in the control group (OR = 0.22; 95% CI - 0.87-0.57; P = 0.002) while the presence of a family history of PCOS (OR = 2, 96; 95% CI - 1.54-5.68; P = 0.001) was more frequent in women with PCOS. CONCLUSIONS: In the studied sample, the deletion polymorphisms of the GSTT1 and GSTM1 genes isolated are not associated with PCOS, but in combination, they may be implicated in the etiology of the condition.

SUMMARY The 2006 Revised Sapporo Classification Criteria for Definite Antiphospholipid Syndrome included as laboratory criteria the tests for antiphospholipid antibodies whose accuracy was regarded as satisfactory according to the evidence available at that time. In practice, however, the sensitivity and specificity of these “criteria” of antiphospholipid antibodies are sometimes insufficient for identifying or ruling out antiphospholipid syndrome. It has been studied whether the accuracy of the laboratory diagnosis of the syndrome could be improved by testing for non-criteria antiphospholipid antibodies. In this work, we review evidence on the clinical associations and diagnostic value of the most commonly studied non-criteria antibodies, namely: antiphosphatidylethanolamine, anti-annexin A5, anti-prothrombin, anti-phosphatidylserine/prothrombin complex, IgA anticardiolipin, and IgG anti-domain I of the β2 glycoprotein antibodies.
Brokers en una red de venta de derechos de uso de tierra: Valle de Rengo, Chile, 1832-1860
Authors: Brangier Víctor , Matheu Alexis
Published: December 2020

RESUMEN El artículo analiza una red de venta de derechos de uso de tierra en un valle de Chile, en periodo de formalización de derechos (1832-1860). Se examina la conducta de brokers desde la noción Agujeros Estructurales, proveniente del Análisis de Redes Sociales. Mediante el estudio de contratos de compra y venta y de catastros agrícolas, se deduce que los brokers privilegiaron comprar tierras mejor valuadas a vendedores de baja participación en la red. La estrategia rindió frutos patrimoniales en pocos brokers vinculados a la administración pública local. Se proyecta la relevancia del hallazgo para la literatura centrada en el ciclo: formalización de derechos/ desposesión campesina.

Preaching, the city, and the saints: an analysis of the civic-liturgical context of the Venit in civitatem suam sermons (1304) by Giordano da Pisa (c. 1260-1311)
Authors: Alves Aléssio Alonso
Published: December 2020

ABSTRACT This article explores the civic-liturgical context of three sermons by the friar Preacher Giordano da Pisa, delivered during a same week of 1304 in Florence (two on Sunday and one on Thursday), all of them from the verse of Matthew 9, 1 (Venit in civitatem suam). Based on considerations regarding the choice of the biblical verse, as well as the examination of other documents of the Dominican Order and two liturgical books of the Florentine cathedral, I argue that the friar deliberately chose not to follow the liturgical customs of sermon composition in these preachings. Thus, it is concluded that this procedure was made to establish a reflection on the city (the quintessential human environment, both on Earth and in Heaven) in view of the civic-religious feast of Saint Reparata, Florence’s patroness saint, which took place on Thursday.
Percepções acerca do Programa Mais Médicos e do Processo de Supervisão Acadêmica

Abstract: Introduction: This study aims to analyze the perceptions of the involved actors about the “Mais Médicos” Program (PMM) and the academic supervision process, its strengths and weaknesses aiming to improve Primary Heath Care practices. Method: Qualitative study carried out through 05 in-depth interviews with PMM supervising doctors, and 24 interviews with unit managers, 12 Primary Heath Care coordinators, and 07 Secondary Health Care doctors. Results: Three thematic axes emerged from de analysis: benefits of the program for the municipalities and for the population; the challenges of the supervisory process and the difficulties of the fragmented health system. Conclusions: The actors’ perception of the “Mais Médicos” Program are positive, especially because it brought doctors to municipalities with vulnerable areas, where doctors did not go to and where they did not stay. Supervision is an important support for continuing in-service training; however, it requires a better articulation with the different levels of the health system management. The precariousness of the service network limits the performance of both doctors and supervisors, demonstrating that it is necessary to invest in a solid and effective care network. Moreover, it was once again evident that the population will face a shortage of doctors due to changes in health policies. It is necessary to build more comprehensive policies, that will not only result in sporadic provision of medical care. There is a need for continuous actions, better integrated to the healthcare networks, aiming at an efficient and effective healthcare system.

O QUE DIZEM CORDELISTAS SOBRE O GÊNERO DISCURSIVO QUE PRODUZEM? UMA ANÁLISE A PARTIR DE REFLEXÕES METALINGUÍSTICAS SOBRE ASPECTOS COMPOSICIONAIS DO CORDEL
Authors: Melo July Rianna de , Silva Alexsandro da , Galvão Ana Maria de Oliveira
Published: December 2020

RESUMO: Este artigo objetiva analisar os dizeres de cordelistas acerca das dimensões composicionais (rima e métrica) do gênero cordel. Para tanto, apoiamo-nos, por um lado, em discussões teóricas sobre gêneros discursivos e literatura de cordel e, por outro, em construtos teóricos do campo da consciência metalinguística e, em particular, da consciência metatextual. Foram selecionados como participantes desse estudo seis poetas, com idades e tempos de escolarização distintos, com os quais foram realizadas entrevistas metalinguísticas, cujos dados foram tratados à luz da análise temática de conteúdo. Os resultados revelaram que os cordelistas eram altamente sensíveis às regras de rima e que, no caso dos poetas mais experientes e menos escolarizados, as lógicas do oral e da performance pareciam ser mais importantes que uma obediência estrita a padrões rímicos pré-determinados. Com relação à métrica, percebemos que certos preceitos eram de difícil verbalização, mesmo para aqueles cordelistas com maior nível de escolaridade. Além disso, alguns poetas menos escolarizados recorriam predominantemente ao recurso do “canto” para se certificar de que os versos estavam metrificados. Desse modo, concluímos que, mesmo quando não eram capazes de verbalizar aspectos composicionais dos cordéis, os poetas – inclusive os pouco escolarizados – engajavam-se em um complexo e sofisticado processo de reflexão metalinguística.
Condição de Classe e Desempenho Educacional no Brasil
Authors: Caprara Bernardo Mattes
Published: December 2020

Resumo: O objetivo do artigo é analisar o impacto da condição de classe dos estudantes brasileiros da educação básica nos seus desempenhos educacionais. Os fundamentos teóricos da pesquisa remetem ao conceito de classe social de Pierre Bourdieu. A partir de uma abordagem quantitativa, utilizamos a base de dados do Sistema de Avaliação da Educação Básica (Saeb), realizado em 2013. As técnicas analíticas mobilizadas foram a estatística descritiva, a análise de correspondência e a regressão linear múltipla. Os resultados empíricos demonstraram a persistência dos efeitos da classe social na conformação dos rendimentos acadêmicos, ainda que coexistindo com os impactos das variáveis de escolarização, de trajetória individual e de caráter pedagógico.
