O Programa de Integração da Educação Profissional com a Educação Básica na modalidade Educação de Jovens e Adultos (Proeja) é uma política governamental institucionalizada pelo Decreto n.º 5.840/2006, com a dupla finalidade de elevar a escolarização e proporcionar a qualificação profissional do público jovem e adulto. Frente à ausência de documentos e de registros, estabelecemos esta pesquisa com o objetivo de verificar o perfil do corpo docente e discente do Proeja, bem como as condições de implantação do programa no Instituto Federal do Acre (Ifac), campus Rio Branco. Para tanto, foi analisado o contexto histórico de fundação da instituição, as planilhas Sistema Nacional de Informações da Educação Profissional e Tecnológica (Sistec), as características comuns aos sujeitos investigados e suas narrativas sobre o processo de implantação. Para a realização desta pesquisa elegemos o método dialético, com abordagem qualitativa, de caráter descritivo e explicativo do fenômeno investigado. A coleta de dados deu-se através dos instrumentos questionários e entrevistas narrativas, os quais foram interpretados com suporte na hermenêutica dialética. Quanto ao perfil dos discentes, verificamos que os concludentes são em maioria mulheres, além disso há uma unicidade nas expectativas e percepções sobre o programa e o Ifac. Os docentes eram especialistas, mestres e doutores, mas não detinham experiência com o público alvo do programa.
A racista desvalorização do trabalho manual e da educação profissional no Brasil
Authors: Dos Reis Leonardo Rangel , Barbosa de Sá Cerqueira Matheus
Published: April 2024

No presente artigo, partindo da hipótese de que a educação profissional no país é desvalorizada por conta do preconceito racista que se tem em relação às pessoas que realizam trabalhos manuais, pretendemos, por meio da metodologia do ensaio como conversa, explicitar argumentos que apontam e comprovam tal afirmação. O pressuposto classista de que o trabalho braçal é indigno é mobilizador de um tipo particular de racismo. Este é muito mais presente no ideário modernizador da educação oficial do que costumamos admitir. Faremos esse experimento do ensaio como conversa ao longo do texto, no intuito de apontar como o preconceito em relação ao trabalho manual e às/aos suas/seus portadoras/res nos atrapalha na criação da educação integrada.

Authors: Duarte Michelle Bobsin
Published: April 2024

Resumo: Este trabalho tem como objetivo contribuir para a reflexão sobre os elementos epistemológicos presentes na filosofia de Hans Jonas. A chave interpretativa fornecida pelo autor, com a noção de Homo Pictor e a importância das imagens, dos símbolos, da imaginação e da memória, na evolução da liberdade humana, no âmbito da vida, que resultou no ser humano atual, proporciona um campo fecundo para a exploração dos atributos dos sujeitos epistêmicos apontados pelo filósofo. Nesse sentido, propõe-se uma leitura que considera os possíveis elementos de uma teoria do conhecimento de Jonas, a partir dos textos “Image Making and the Freedom of Man” (1966), com destaque ao apêndice do ensaio, intitulado “On the Origins of the Experience of Truth” e do texto “Tool, Image, and Grave” (1986).

Abstract Nitrogen compounds, particularly ammonium, nitrite and nitrate, are a major problem in shrimp production systems. These compounds can accumulate in the aquatic environment and reach harmful or even lethal levels. Thus, monitoring the levels of nitrogenous compounds such as ammonia and studying their effects on the animals are essential. One tool used for this purpose is acute toxicity testing based on the evaluation of LC50 values. Furthermore, tools that can help improve the performance of aquatic organisms in culture are needed. The present study aimed to evaluate the effect of salinity on the toxicity of total ammonia to postlarvae of the freshwater prawn Macrobrachium rosenbergii. For this purpose, acute toxicity testing (LC50-96h) was performed using 540 postlarvae with a mean weight of 0.13 g and a mean total length of 2.47 cm, divided into 54 experimental units of two liters each. A completely randomized design in a 3×6 factorial scheme was used, combining three salinities (0, 5, and 10 g.L-1) and six total ammonia concentrations (0, 8, 16, 32, 64, and 128 mg.L-1), with three replicates per combination. The LC50 values for M. rosenbergii postlarvae at 24, 48, 72, and 96 h and their respective confidence intervals (95%) were estimated using the trimmed Spearman-Karber method. The results showed that salinities of 5 or 10 g.L-1 did not reduce the acute toxicity of total ammonia.

Published: April 2024

Abstract Background Anatomical variations in arteries of the upper limb, such as presence of an accessory brachial artery, are common and widely described in the literature, mainly in cadaveric studies, but it is now possible to diagnose them using vascular Doppler ultrasound. Objectives To identify the incidence of accessory brachial artery using vascular Doppler ultrasound and compare the findings with cadaveric studies. Methods This was a prospective study that examined 500 upper limbs of 250 volunteers assessed with vascular Doppler ultrasound using the Sonosite Titan portable ultrasound machine. Results 15.6% of the participants in our study had the accessory brachial artery anatomical variation. Our percentage is in line with the average rates found in cadaveric studies, which ranged from 0.2% to 22%. Being aware of this variation is fundamental in procedures such as peripheral venipuncture, arteriovenous fistula creation, catheterization, forearm flaps, emergency surgeries on the limb and even correction of fractures by cast. Conclusions The accessory brachial artery is a frequent variant in the upper limb. The percentage of individuals with an accessory brachial artery in our study was 15.6%, which agrees with data from the literature on cadaveric studies.

Authors: Lopes Carla Cristine Silva , Teixeira Rivanda Meira
Published: April 2024

Abstract Purpose: The contributions of individuals in the innovative process and the way they learn are crucial. However, the various entrepreneurial learning modes are neglected in discussions about innovation. That said, innovation is considered to emerge from continuous learning processes and the accumulation and development of knowledge from relationships, experiences, skills, and information. Thus, this work aims to identify how small business entrepreneurs adopt the different learning modes in their innovation actions. Originality/value: The academic contribution of this research is to present initial steps regarding entrepreneurial learning modes in conjunction with innovation. On the other hand, the practical contribution refers to understanding the different forms of learning that can be considered for innovation, which the study will provide to small business entrepreneurs. Design/methodology/approach: The research strategy adopted was multiple case studies and content and cross-case analysis techniques were used for data analysis. Findings: Research results show that experiential, through networks, formal, and vicarious learning are important modes to help entrepreneurs achieve market distinction through innovative solutions. Thus, the knowledge accumulation provided by the different learning modes studied resulted in implementing various innovation actions, mainly in services, in the companies participating in the study.

Authors: Silva Catarina Sousa , Brandão Sónia , Azevedo Ana Rita , Prata Ana Paula
Published: April 2024

Abstract Objectives: to identify the factors and variables that interfere with the maternal perception of security at postpartum. Methods: a cross-sectional study, carried out in three Portuguese hospital units, with a non-probabilistic sample of 352 puerperal women, recruited from the postpartum units on the day of hospital discharge after delivery. Maternal sociodemographic and obstetric characteristics, as well as data on monitored pregnancy, childbirth and infant feeding, were collected through the application of a questionnaire developed by the researchers. For the analysis of maternal perception of security, the instrument “Parents’ postnatal sense of security” (PPSS) was used. Descriptive and inferential statistics were used for data analysis. Results: women who lived with their partner (t (349) = - 2.34, p=0.020), were multiparous (t (349) = - 2.26, p=0.025), had pregnancy monitored (t (349) = -3.25, p=0.001), had a positive childbirth experience (F (1, 351) = 7.07, p=0.008) and those who exclusively breastfed during hospitalization (F (2, 351) = 11,43, p<0.001), presented greater perception of security at postpartum. Conclusions: the factors that affect the maternal perception of security at postpartum are cohabitation with a partner, parity, monitored pregnancy, childbirth experience and infant feeding. Defining which factors interfere with maternal security at postpartum may contribute to the construction of intervention programs that promote the maternal perception of security at the time of hospital discharge after delivery.

Authors: Silva Jailson dos Santos , Leite Maria Silene Alexandre
Published: April 2024

Abstract Given the importance of structuring organizations in supply chains as a mechanism for competitiveness, as well as process management for the good operational performance of these chains, this article aims to map and analyze the business processes of a supply chain of the ceramic sector located in northeastern Brazil. To achieve the proposed objective, Lambert, Cooper, and Pagh’s (LCP) model of supply chain management is adopted, which comprises, within its analysis dimensions, the mapping of the dimensional structure of the chain, its processes, and management components. As a result, it was possible to characterize the configuration of the chain under analysis, highlighting the company's proximity focused on the upstream direction of the chain and, consequently, the complexity of the supply operations. Furthermore, based on the problems and inefficiencies identified during the mapping of the supply processes, this study proposes suggestions for changes and improvements to the ceramic sector's supply chain analyzed. By providing a detailed analysis of the dimensional structure of the chain, its processes, and managerial components, this article contributes to the continuous improvement of organizations by providing a practical discussion on the structuring of supply processes and emphasizing the importance of overcoming the identified inefficiencies.

Authors: Montiel Mariana , Wilhelmi Miguel R. , Mannone Maria
Published: April 2024

Abstract The mathematical music composition workshop, an endeavor that integrates mathematics and music majors, is a concrete example of a STEAM (science, technology, engineering, arts, and mathematics) project. In this article, the authors analyze how mathematics students and music composition students have worked together, have learned to interpret specialized languages from one another, and have presented their results to a public interested in the relationship that guards these two disciplines. The goal of improving the understanding of abstract mathematical concepts through the application to musical structures is analyzed using the Onto-semiotic Approach (OSA). This framework sheds light on some of the written and oral manifestations of the students who participated. The mathematical competence that the participants were expected to achieve through this interdisciplinary endeavor are privileged in this article over the music education goals (which were also present).

Authors: Acevedo Nicolás Sánchez , Guerrero Leticia Sosa , González Luis Carlos Contreras
Published: April 2024

Resumen El uso de ejemplos por parte de los profesores es un indicativo del conocimiento didáctico del contenido (PCK) y, la amalgama entre el conocimiento matemático y el didáctico para la enseñanza es un reflejo de la comprensión de la forma en que se enseñan los contenidos matemáticos y del aprendizaje de los estudiantes. En este trabajo nos proponemos describir el conocimiento especializado movilizado y las posibles relaciones a partir del uso de ejemplos en la enseñanza de la ecuación cuadrática. La investigación es un estudio de caso instrumental bajo un paradigma interpretativo. El conocimiento especializado se examina a la luz del modelo Mathematics Teachers’ Specialized Knowledge centrándonos en los ejemplos utilizados por la profesora de acuerdo con categorías derivadas de la literatura. Los hallazgos de la investigación, de acuerdo con los ejemplos usados, permiten establecer relaciones entre los diferentes conocimientos movilizados por la profesora. En particular, las evidencias sugieren que el PCK de la profesora influye en el tipo de ejemplos usados y el conocimiento matemático (MK) puesto en juego en la enseñanza de la ecuación cuadrática.

Authors: Piñero Charlo José Carlos , Canto López María del Carmen , Caballero Leiva Cristina
Published: April 2024

Resumen El objetivo del presente trabajo es realizar un seguimiento y tratamiento de la ansiedad matemática presente en un grupo de maestros en formación. A tal fin se implementaron experiencias de Aprendizaje Basado en Juegos, que sustituyeron a las sesiones prácticas convencionales a lo largo de todo un curso académico. Al traducir las sesiones prácticas a juegos, no se obtuvieron diferencias significativas en cuanto al rendimiento académico. En cambio, éstas afectaron fundamentalmente a la reducción global de la ansiedad mostrada hacia la evaluación en matemáticas (-10.6%) y las tareas numéricas (-8.4%). El estudio evidencia una mejora de la ansiedad matemática, siendo lo suficientemente significativa como para considerar que la ludificación de tareas y la gamificación de la evaluación son procedimientos que contribuyen positivamente a la formación de futuros maestros de matemáticas.

Published: April 2024

Introduction: Percutaneous kidney biopsy (KB) is crucial to the diagnosis and management of several renal pathologies. National data on native KB in pediatric patients are scarce. We aimed to review the demographic and clinical characteristics and histopathological patterns in children who underwent native percutaneous KB over 24 years. Methods: Retrospective observational study of patients undergoing native percutaneous KB in a pediatric nephrology unit between 1998 and 2021, comparing 3 periods: period 1 (1998–2005), period 2 (2006–2013), and period 3 (2014–2021). Results: We found that 228 KB were performed, 78 (34.2%) in period 1, 91 (39.9%) in period 2, and 59 (25.9%) in period 3. The median age at KB was 11 (7–14) years. The main indications for KB were nephrotic syndrome (NS) (42.9%), hematuria and/or non-nephrotic proteinuria (35.5%), and acute kidney injury (13.2%). Primary glomerulopathies were more frequent (67.1%), particularly minimal change disease (MCD) (25.4%), IgA nephropathy (12.7%), and mesangioproliferative glomerulonephritis (GN) (8.8%). Of the secondary glomerulopathies, lupus nephritis (LN) was the most prevalent (11.8%). In group 1, hematuria and/or non-nephrotic proteinuria were the main reasons for KB, as opposed to NS in groups 2 and 3 (p < 0.01). LN showed an increasing trend (period 1–3: 2.6%–5.3%) and focal segmental glomerular sclerosis (FSGS) showed a slight decreasing trend (period 1–3: 3.1%–1.8%), without statistical significance. Conclusions: The main indication for KB was NS, which increased over time, justifying the finding of MCD as main histological diagnosis. LN showed an increase in incidence over time, while FSGS cases did not increase.

Authors: Paredes Suyene de Oliveira , Forte Franklin Delano Soares , Dias Maria Socorro de Araújo
Published: April 2024

RESUMO Estudo compreendeu o trabalho dos cirurgiões-dentistas da Estratégia Saúde da Família, na perspectiva da Promoção da Saúde Bucal (PSB) em território rural. Trata-se de uma investigação transversal e qualitativa. A coleta dos dados foi realizada a partir de entrevistas semiestruturadas realizadas com quatorze profissionais que atuavam em equipes de saúde bucal rurais do estado da Paraíba. Para compreensão e sistematização dos dados, adotou-se a análise de conteúdo temática. O referencial teórico condutor do método considerou pilares, valores e princípios da Promoção da Saúde (PS). As narrativas revelam conceitos imprecisos de PSB, restringindo-os às atividades de prevenção aos agravos bucais. Existem potencialidades e fragilidades nas ações de PSB em áreas rurais. Há desigualdades quanto às unidades de apoio e existem populações rurais sem qualquer assistência aos serviços especializados de saúde bucal.

Distorcionismo: uma nova categoria de análise para o campo de batalha da história no século XXI
Authors: Joffily Mariana , Ramalho Walderez
Published: April 2024

Resumo: Entre os maiores desafios ético-políticos da historiografia no século XXI estão as práticas de falsificação e manipulação do passado. Este artigo propõe a categoria distorcionismo, assinalando sua particularidade em relação ao revisionismo e negacionismo e oferecendo exemplos de sua aplicabilidade, tendo a ditadura militar brasileira como campo de análise. Problematiza e sugere um remanejamento dos significados atribuídos a esses conceitos, buscando precisar as fronteiras entre operações legítimas e abusivas no exame do passado. Justifica a pertinência da categoria distorcionismo argumentando que ela permite dar maior precisão conceitual na tarefa de caracterizar e historicizar as estratégias retóricas utilizadas para deturpar a história, as quais não se reduzem a operações de negação de eventos e processos históricos consolidados ou de revisão interpretativa do passado.

A nonlinear model for consolidated geotextile-encased sand columns (GESACs) was formulated. The model is based on a power law and predicts the stress–strain curve of a consolidated GESAC based on the superposition rule, wherein the stress–strain curve of the unconsolidated GESAC is superposed by the stress–strain curve of the soil alone in a consolidated triaxial test. A uniaxial compression test was conducted to study the failure mechanism of the GESAC. In addition, unconsolidated and consolidated triaxial tests on loose GESACs were conducted to investigate the effect of initial stresses on the shear behavior of GESACs. To further investigate the interaction between the soil and geotextile, and to assess the GESAC model, finite-element simulations were conducted. The results showed that internal lateral stresses developed in the GESAC due to the confining effect of the geotextile, which increased the circumferential tension force on the geotextile while the p–q path of the GESAC approached the critical state line and followed the line when the shear strength of the soil was mobilized. The model was verified based on data on dense consolidated GESACs found in the literature and the measured and predicted results showed good agreement.
THE FOURTH INDUSTRIAL REVOLUTION: ON THE PROSPECTS OF DIGITAL TRANSFORMATION IN RUSSIA

Published: April 2024

Digital technologies, the introduction of which began in the middle of the last century and subsequently acquired significant proportions, have become the most important tool for progressive development in various areas of public life. In industry, they are a means of improving the factors of production. The progressive development of the last decades is linked to the course of the third industrial revolution. The author of the article designates the current period as a transitional period between the third and fourth industrial revolution. The article notes the accelerating growth of the global technology markets associated with the processes under consideration. The dominance of companies from the United States, with which firms from Western Europe compete, is noted. There is a weak manifestation of these trends in the Russian markets. At the same time, it is emphasized that digital transformation has been adopted in Russia as a national development goal, with the corresponding consolidation of action plans in the program for the development of the manufacturing industry. The conclusion is made about the preparatory stage of the digital transformation of the domestic industry at the present time, as well as the assumption about the possibility of achieving parity with the leading countries in this area in the event of the start of large-scale implementation of planned activities.
Impact of perceptual-learning strategies and background noise on disordered speech intelligibility
Authors: Paul M Evitts , Connie K Porcaro , Tom Gollery
Published: April 2024

Objective: There is a plethora of research showing reduced speech intelligibility for a variety of voice disorders (i.e., dysphonia, alaryngeal). Therapeutic approaches to improve intelligibility typically involve targeting the speaker (e.g., clear speech, reduced rate) with minimal attention to the listener. Therefore, there were three purposes of this study: 1) to determine the impact of background noise on the speech intelligibility of disordered speakers; 2) to determine the impact of providing listeners with perceptual-learning strategies on the speech intelligibility of speakers with a voice disorder; and 3) to determine if subjective ratings of voice quality can predict speech intelligibility. Methods: Sentences were recorded from 12 speakers (2 typical, 3 alaryngeal, 7 dysphonic). Sentences were divided into one of three groups of signal-to-noise ratios (SNR: quiet, +5 dB SNR, and 0 dB SNR) and individually presented to 129 healthy listeners divided into one of three groups (i.e., control, acknowledgment of disorder, cognitive-perceptual strategies). Orthographic transcription was used to assess speech intelligibility. In addition, three expert listeners provided subjective voice quality ratings of all speakers. Results: Listeners had significantly more intelligibility errors with increased background noise (p <.001) and providing strategies to listeners did not result in a statistical improvement level F(6, 486) = 1.53, p = .17, η2p = 0.02. Regression analysis showed that the subjective voice quality overall severity was able to predict speech intelligibility in the noisy condition (0 dB SNR), accounting for 37% of the variance, R2 = .365, F(1,10) = 5.759, p = .037. Conclusion: Results suggest that increased background noise has a deleterious effect on the speech intelligibility of those with a voice disorder but that providing listeners with strategies in hopes of improving speaker intelligibility was not successful. Results did provide support, however, for the use of subjective voice quality ratings as a potential index of speech intelligibility.
Transcriptional profiling reveals fundamental differences in iPS-derived CD34+ Cells versus adult circulating CD34+
Authors: Elmira Jalilian , William Raimes , Roberto Martinez Macias
Published: April 2024

CD34+ cells hold significant promise in regenerative medicine and the treatment of various vascular degenerative diseases primarily because of their ability to regenerate and differentiate into various cell types. These cells can be derived from embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), or adult stem cells like blood and bone marrow, and can differentiate into endothelial, hematopoietic, myeloid, and other cell types. However, their characteristics vary based on the source, making detailed definitions essential for specific therapeutic applications. In this study, it was aimed to compare these two different CD34-positive cell populations by full genome transcriptional profiling (RNAseq). To this end, we first optimized a CD34+ cell differentiation protocol and found that Vascular Endothelial Growth Factor (VEGF) is critical for the transition of cells from mesodermal precursors to CD34+ cells. Additionally, principal component analysis (PCA) of RNAseq data showed that blood-derived CD34+ cells clustered far from iPS-derived CD34+ cells which illustrates these populations are fundamentally different. This data will be useful to better define these cell populations and facilitate the translation of regenerative approaches in this field as well as providing potentially novel diagnostic tools.

Authors: Talty Caiti-Erin
Published: April 2024

This is a protocol to describe the materials and methods utilized to perform preclinical traumatic brain injury (TBI) using a closed-head controlled impact model in adult rats. The model utilizes an electromagnetic actuator to deliver an impact to the intact scalp and has been optimized for use in adult rats. A skull template is used to mark the impact site and the injury parameters can be adjusted according to the desired severity of impact using the control box. The posting of this protocol is part of the mission of the PREClinical Interagency reSearch resourcE-TBI (PRECISE-TBI, precise-tbi.org) to improve clinical translation of therapeutics by providing an online catalog and standardized protocols to reduce the variability of model usage between laboratories.
The role of variant anatomy in neurosurgery
Authors: Shnyakin P. G. , Rudenko P. G. , Gasimova N.  D.
Published: April 2024

Variants of atypical structure and location of anatomical structures always complicate the course of surgical access and admission and are often the causes of surgical errors and complications. This article presents an overview of some features of variant anatomy in areas of interest to neurosurgeons, including those leading to the development of intraoperative problems and postoperative neurological deficits.

The main message of the article is not only that neurosurgeons should plan surgery taking into account individual anatomical variability starting with the shape of the skull, but also that in cases of adverse perioperative events, atypical anatomy should be taken into account as an objective risk factor and have a mitigating value in the evaluation of the neurosurgeon’s performance.

The aim of this paper is to present and analyse scientific publications on variant anatomy, determining its role in the development of surgical errors and complications in neurosurgery.

Background. Cavernoma of cavernous sinus is a fairly rare benign neoplasm, accounting for less than 3 % of all neoplasms in this area. Due to the rarity of this pathology, a standardized protocol for diagnosis or treatment has not been developed. Surgical and radiosurgical methods are used for treatment.

Aim. Analysis of the results of treatment of patients with cavernous sinus cavernomas operated at the N. N. Burdenko National Medical Research Center of Neurosurgery from 2000 to 2022 using endoscopic transnasal access.

Materials and methods. We present our own experience in the treatment of 9 patients who underwent transnasal endoscopic removal of cavernous sinus cavernoma.

Results. A total of about 300 cases of treatment of patients with cavernous sinus cavernomas have been described in the literature, and endoscopic removal has been described in only 12 cases.

As a result, subtotal removal was achieved in 7 cases. In 2 cases, the removal was partial. The postoperative period proceeded in all patients without peculiarities and without complications.

Conclusion. Endoscopic transnasal access allows partial or subtotal removal of the formation without risk of injury to cranial nerves and with minimal soft tissue injury, which has a positive effect on the postoperative period of patients. In combination with radiosurgical methods, it is possible to achieve satisfactory treatment results.
