Changing the voice characteristics of a person under the influence of alcohol intoxication affects the effectiveness of the identification procedure. From which it follows that the determination of the level of alcohol in the blood remotely is important for ensuring information security in computer systems. The purpose of the present paper is to analyze the existing voice authentication methods and approaches to improve accuracy, analyze existing data sets, and evaluate the influence of the psychophysiological state of the speaker on the parameters of his speech. The focus of this study is on exploring different approaches to recognizing alcohol intoxication and evaluating their effectiveness. The study includes a comparative analysis of these methods, emphasizing the importance of using a comprehensive and representative data set that takes into account factors such as gender, age, stage of intoxication, recording quality, and ambient noise levels. Based on the analysis of scientific publications, the study identifies the random forest method as one of the most effective machine learning methods, demonstrating an accuracy of 95.3% for all speech datasets and 80% for the widely used Alcohol Language Corpus.

Published: May 2024

Insafing allows you to form and discuss tasks from the field of science, education, design. Insafing is understood as an intelligent interactive communication technology that begins to form on the basis of the theory of dynamic information systems. Thus, insafing, as a TDIS application, has a great potential for visualizing our activity, generalizing traditional circuit techniques due to the presence of special rules, structures and its own language for reengineering and optimizing business processes. The article discusses the use of insafing for the analysis of business processes, highlighting the processes that the owner should control and optimize directly. As a result of the use of insafing for the analysis and optimization of business processes of the organization, triads were obtained that allow determining the success factors of an economic entity in the modern economy. These are qualified personnel, decent remuneration, division of management into tactical and strategic levels, developed channels of information exchange and intangible motivation.

Authors: Vincent Chandan , Venkatesan Aakash , Rai Dinakar , Muthuswamy Arvind
Published: May 2024

Background. NPWT has been used to treat various wounds. Scant evidence exists on the use of custom-made NPWT for infected wounds. NPWT dressings promote wound healing by increasing local blood flow and antibiotic concentration, and by removing exudates from the wound. Objective. To report the use of custom-made NPWT dressings to manage complex infected wounds of the lower limb. Materials and Methods. The authors retrospectively reviewed the records of 43 patients with complex infected wounds of the lower limb treated with debridement and low-cost, custom-made NPWT dressing connected to wall suction from January 1, 2018 to December 31, 2020, at PSG Medical College Hospital, Coimbatore, India. Results. A total of 43 patients with infected wounds of the lower limb were treated with the custom-made NPWT dressings. Second-look debridement was required in 5 patients. An average of 5 dressing changes were required for optimal wound granulation, with 23% of patients (n = 10) requiring secondary suturing and 62% (n = 27) requiring STSG for definitive coverage of the wound. Healing by secondary intention was achieved in 6 patients. The average duration from the start of therapy until the wound was ready for coverage (STSG or secondary suturing) was 2.5 weeks (range, 1–5 weeks), with an average time to complete wound healing of 5 weeks (range, 3–7 weeks). The most common wound isolate was Staphylococcus aureus (60%). No complications occurred. Conclusions. Custom-made NPWT dressings are safe to use in complex infected lower limb wounds. These dressings keep the wound dry and promote healing. Wound debridement followed by NPWT combined with antibiotic therapy can act synergistically to promote wound healing and control infection.

Authors: Jiang Fengying , Liu Qingyang , Wang Qiubo
Published: May 2024

Background. Anemia is prevalent among patients with T2DM with DFU. However, there is limited research on the relationship between Hb level and DFU. Objective. To investigate the characteristics and relationship between Hb level and prognosis in patients with DFU. Materials and Methods. A total of 212 patients with T2DM were included and grouped according to the presence (n = 105) or absence (n = 107) of DFU. The independent t test and multiple logistic regression analysis were used to analyze the effect of different factors on the occurrence of anemia in patients with DFU and whether Hb level could be used to predict prognosis. Results. There were significant differences in clinical indicators that directly or indirectly contributed to anemia in patients with DFU (P < .05). Hb level was independently associated with DFU (OR, 0.899; P < .05). Hb levels were significantly decreased in patients aged 65 years or older (P < .05). Mild anemia was prevalent among most patients with DFU (59.62%). Hb level decreased with the severity of foot ulcer (P < .05) and was correlated with the duration of diabetes (R2 = 0.653; P < .05). The AUC value was 0.82, with a cutoff value of 122.5 g/L to identify patients with DFU at high risk of adverse outcomes. Conclusion. Anemia is common in patients with DFU. Anemia is a marker of DFU severity, and Hb level can predict poor prognosis in patients with DFU.

X-ray diffraction is a commonly used technique in the pharmaceutical industry for the determination of the atomic and molecular structure of crystals. However, it is costly, sometimes time-consuming, and it requires a considerable degree of expertise. Vibrational circular dichroism (VCD) spectroscopy resolves these limitations, while also exhibiting substantial sensitivity to subtle modifications in the conformation and molecular packaging in the solid state. This study showcases VCD's ability to differentiate between various crystal structures of the identical molecule (polymorphs, cocrystals). We examined the most effective approach for producing high-quality spectra and unveiled the intricate link between structure and spectrum via quantum-chemical computations. We rigorously assessed, using alanine as a model compound, multiple experimental conditions on the resulting VCD spectra, with the aim of proposing an optimal and efficient procedure. The proposed approach, which yields reliable, reproducible and artifact-free results with maximum signal-to-noise ratio, was then validated using a set comprising of three amino acids (serine, alanine, tyrosine), one hydroxy acid (tartaric acid), and a monosaccharide (ribose) to mimic active pharmaceutical components. Finaly, the optimized approach was applied to distinguish three polymorphs of the antiviral drug sofosbuvir and its cocrystal with piperazine. Our results indicates that solid-state VCD is a prompt, cost-effective, and easy-to-use technique to identify crystal structures, demonstrating potential for application in pharmaceuticals. We also adapted the cluster and transfer approach to calculate the spectral properties of molecules in a periodic crystal environment. Our findings demonstrate that this approach reliably produces solid-state VCD spectra of model compounds. Although for large molecules with many atoms per unit cell, such as sofosbuvir, this approach has to be simplified and provides only a qualitative match, spectral calculations and energy analysis helped us to decipher the observed differences in the experimental spectra of sofosbuvir.

Published: May 2024

Leveraging the increasing volume of chemical reaction data can enhance synthesis planning and improve suc- cess rates. However, machine learning applications for retrosynthesis planning and forward reaction prediction tools depend on having readily available, high-quality data in a structured format. While some public and licensed reaction databases are available, they frequently lack essential information about reaction condi- tions. To address this issue and promote the principles of findable, accessible, interoperable, and reusable (FAIR) data reporting and sharing, we introduce the Simple User-Friendly Reaction Format (SURF). SURF standardizes the documentation of reaction data through a structured tabular format, requiring only a basic understanding of spreadsheets. This format enables chemists to record the synthesis of molecules in a format that is both human- and machine-readable, making it easier to share and integrate directly into machine- learning pipelines. SURF files are designed to be interoperable, easily imported into relational databases, and convertible into other formats. This complements existing initiatives like the Open Reaction Database (ORD) and Unified Data Model (UDM). At Roche, SURF plays a crucial role in democratizing FAIR reaction data sharing and expediting the chemical synthesis process.

Authors: Hu Junjie , Wu Peng
Published: May 2024

As large-scale language models continue to expand in size and diversity, their substantial potential and the relevance of their applications are increasingly being acknowledged. The rapid advancement of these models also holds profound implications for the design of stimulus-responsive materials used in drug delivery over the long term. To optimize large models for extensive dataset processing and comprehensive learning akin to a chemist’s intuition, integrating deeper chemical insights is imperative. Our study initially contrasted the performance of Bigbrid, Gemma, GPT NeoX, etc., specifically focusing on designing photoresponsive drug delivery molecules. We gathered excitation energy data through computational chemistry tools and further explored light-driven isomerisation reaction as a critical mechanism in drug delivery. Our study explored the effectiveness of incorporating human feedback into reinforcement learning to imbue large models with chemical intuition, improving their understanding of relationships involving -N=N- groups in photoisomerisa-tion transitions of light-responsive molecules. Despite progress, the limited availability of specialized domain datasets continues to be a significant challenge in maximizing the performance of large models.
Reversible Control of cAMP Activity in Living Cells by Visible Light
Authors: Haag Christoph , Erl Julia , Helbig Korbinian , Wegener Joachim , Koenig Burkhard
Published: May 2024

Cyclic adenosine monophosphate (cAMP) is one of the most prominent molecules involved in intracellular signaling. As a second messenger, it regulates a plethora of biochemical processes that are essential to keep a cell alive and orchestrates physiological responses to external stimuli. Ever since its discovery, great efforts have been made to elucidate all the molecular mechanisms involved in cAMP-mediated signaling cascades. However, experimental evidence suggests that cAMP-mediated signal transduction is much more complex than previously assumed. For new insights, it is crucial to study the real-time dynamics and reversibility of the cAMP-related signaling mechanisms, which often remain disguised by classic pharmacological assays or modulators of cAMP signaling. By chemically attaching a photoswitchable moiety to cAMP, we got control over the biological activity of the molecule through visible light of different wavelengths. Combined with label-free electric cell-substrate impedance sensing (ECIS), the dynamic response of living cells treated with photochromic cAMP has been monitored in real-time while the cAMP-mediated signaling cascade is reversibly switched on and off by visible light with high temporal resolution.
Alignment and Actuation of Liquid Crystals via 3D Confinement and Two-Photon Laser Printing

Published: May 2024

Liquid crystalline (LC) materials are especially suited for the preparation of active 3D/4D microstructures using two-photon laser printing. To achieve the desired actuation, the alignment of the LCs must be controlled during the printing process. In most cases studied to date, the alignment relied on surface modifications and therefore, complex alignment patterns and concomitant actuation were not possible. Here, we introduce a strategy for spatially aligning LC domains in three-dimensional space by utilizing 3D-printed polydimethylsiloxane-based microscaffolds as confinement barriers, which induce the desired director field. The director field resulting from the boundary conditions is calculated with Landau de Gennes theory and validated by comparing experimentally measured and theoretically predicted birefringence patterns. We demonstrate our procedures for structures of varying complexity and then employed to fabricate 4D microstructures that show the desired actuation. Overall, we obtain excellent agreement between theory and experiment. This opens the door for rational design of functional materials for 4D (micro)printing in the future.
Deciphering the Atomic Size Factor in Quasi-ternary Zintl phases RAg0.5Al0.5Ge (R = Ca, Eu) with the TiNiSi type Structure
Authors: Ponou Simeon , Mudring Anja-Verena
Published: May 2024

The targeted synthesis of two analogous quasi-ternary Zintl phases CaAg0.5Al0.5Ge and EuAg0.5Al0.5Ge were conducted by direct reaction of stoichiometric mixtures of the elements at high temperature and, their crystal structures refined from single-crystal X-ray diffraction data. These pseudo-ternary structures are intended to probe the generalization of the pseudo-element concept to the small polarizing cation component of the ternary isovalent Zintl phases CaMgGe and EuMgGe, with the complete replacement of the divalent Mg position by an equiatomic mixture of monovalent Ag and trivalent Al atoms, while the TiNiSi type structure (space group Pnma) is retained. The two title phases are almost line compounds without significant experimental phase width. However, the calculated band structure of the hypothetical ordered model of Ca2AgAlGe2, based on first principles DFT method (LMTO code), predicted the compound to be metallic. The chemical bonding analysis with the help of crystal orbital Hamilton population (COHP) could confirmed that, due to the difference in atomic size between Ag and Al, the Al–Ge contacts are localized 2c-2e bonds, in contrast to the more polar and non-localized Ag–Ge bonds. Hence, the ionic formulation should be (Ca2+)2Ag+(4b-Al–)(2b-Ge2–)2, according to the Zintl-Klemm concept (2b- and 4b- indicated two bonded and four bonded atoms). This is also in agreement with an electron localization function (ELF) topology analysis, revealing monosynaptic valence basins on Ge atoms (lone pairs) and only on the Ge–Al bonds (two-center, two-electron bond). Thus, due to the similar atomic size between Al and Ge, an accumulation of charge density on the severely distorted AlGe4 tetrahedra is observed leading to strong Pauli repulsion between the localized electron pairs, while Ag–Ge bonds are depleted. These findings are interesting regarding the influence of the geometric factor on the stability and physical properties of the TiNiSi type structural family in general.

Published: May 2024

Ionic liquids (ILs) are used in numerous chemical, biological, and physico-chemical applications. Native impurities in the IL, however, often limit the interpretation of results or the applicability of these chemicals. Here, we present an electrochemical approach, where the quality of ILs is visualised with cyclic voltammetry using well-defined single-crystal electrodes. As an example, we study Au(111) in N-methyl-N-propylpiperidinium bis(trifluoromethane)sulfonimide ([MPPip][TFSI]), where different suppliers with different supplied purity and different pretreatments are considered. The importance of studying the quality of ILs after pretreatments is illustrated with additional X-ray photoelectron spectroscopy measurements. We also show that the storage conditions and time/age can have a significant impact on the amount of water and oxygen in the IL. The relevance of reporting metadata and the role of databases in elucidating benchmark systems is also discussed.

Published: May 2024

Currently, the applicable scope of unmanned aircraft application is increasingly expanding. The promising field of unmanned aircraft enhancement is the implementation of some collaborative actions during controlled flight. This paper considers some issues of the group application of unmanned aerial vehicles (UAV) related to the coordinated planning and control of UAVs performing surveillance missions. Performing aerial search operations is technically complicated by the requirement to recognize a search object in arbitrary conditions, which can be both simple and severe environment. The search area is limited by the UAV capabilities, so, in order to improve the efficiency of search operations, UAVs are combined into groups. An algorithm for solving the problem of object search in arbitrary conditions by a group of unmanned aircraft is proposed. The advantage of search by a group of unmanned aircraft is the coverage of the larger search area in a conventional unit of time. This paper addresses the unmanned aircraft configuration, containing both the means of collaborative flight operation and a synthetic vision system. The image obtained by the synthetic vision system is both a source of navigation information and a means which reliably determines the result of search operations. Depending on the conditions of search operations, the image obtained by the synthetic vision system may require additional processing to use as intended. A fusion algorithm is proposed, which is characterized by adaptive adjustment of parameters in each frame individually for different image fragments. Based on the results obtained, it is planned to create a new product for commercial operation of unmanned aircraft.

The paper considers the application of pretrained neural networks to solve the problem of reverse searching of X-ray images of prohibited items and substances. The purpose of the work is to conduct an analysis and substantiate ways to improve the efficiency of baggage and passenger hand luggage X-ray image recognition systems. An analysis of existing domestic and foreign works in the field of baggage and passenger hand luggage X-ray image recognition is presented. It has been revealed that, despite the achieved results in the development of algorithms for recognizing prohibited items and substances, they do not fully cope with such a complexity factor as the overlay of objects. To solve this problem, the paper proposes to additionally analyze X-ray images with low confidence in object recognition. This stage includes the following steps: image segmentation, extraction of features of segmented image elements; search for similar images in the database; decision-making on the class of segmented image elements. This article discusses the last three steps. Variants of approaches to feature extraction from images are analyzed, particularly those based on the application of convolutional autoencoders and pretrained neural networks. The approach based on the application of pretrained neural networks is chosen. The ResNet-50 architecture neural network, pretrained on the ImageNet collection, is used during the work. In order to apply this model to extract image feature vectors, the last classification layer was preliminarily removed. All the previous layers of the model encode the image into a vector. ResNet-50 generates a 2048-dimensional feature vector of images. The principal component analysis is used to reduce the dimensionality of the image feature vectors. The decision of whether the segmented image element is a prohibited item or substance is considered as a reverse search problem using the k-nearest neighbor algorithm. In this case, the class of the X-ray image element is the class most frequently encountered among the K nearest neighbors. In order to test the proposed approach, a training dataset, including 4,635 images of individual items and substances that may be encountered in baggage and passenger hand luggage, was generated. A comparative analysis of image indexing and image search under different algorithms and feature number is presented. A comparative analysis of the model accuracy is provided. It is concluded that the most acceptable is the “Brute force” algorithm in combination with the principal component analysis.

Impact of Legalization on Cannabis Use, Attitudes, and Purchasing Preferences: A Repeated Cross-Sectional Survey of Canadian Young Adults
Authors: Bradley Abigail , Salmon Melissa , Wohl Michael , Howard Andrea
Published: May 2024

Objective: The Government of Canada legalized recreational cannabis use in October of 2018 with the implementation of the Cannabis Act. The act aimed to reduce the illicit cannabis market, improve consumer health outcomes, and reduce youth access to cannabis. However, little is known about the attitudes and behaviors of young adults, who have been shown to have a high prevalence of cannabis use, towards cannabis after legalization. Method: In this descriptive study, we examined cannabis use, attitudes, and purchasing preferences among Canadian university-attending young adults both before and after the legalization of cannabis. Participants were recruited from a large Canadian university from 2017 to 2021. Results: Our findings showed that there was an increase in cannabis use immediately following legalization that subsequently decreased in later years. Additionally, attitudes about the legalization of cannabis became more favorable in later years (following legalization), particularly among those who did not use cannabis. Most young adults were also keen to purchase cannabis from a government-owned store before legalization. However, with the exception of past-month consumers, this preference decreased substantially following legalization. Conclusions: The current research adds to the knowledge base about changes in cannabis-related attitudes and use after legalization and focuses on a key population – young adults.

Não-binariedade de gênero e marcação de gênero neutro de acordo com a mídia jornalística: a construção de sentido em diálogo com as noções de crença e preconceito linguístico
Authors: Baldez Diovana da Silveira
Published: May 2024

É propósito do presente artigo investigar de que forma é abordada na mídia o uso de marcações de gênero neutras, considerando o uso da vogal -e e a alteração de pronomes para a referência de um terceiro gênero. Para tal, foi selecionada para análise uma matéria noticiada em 2019 pelo telejornal Café com Jornal, da Rede Bandeirantes, que aborda a inclusão do pronome they singular no dicionário Merriam-Webster e abrange alternativas de neutralização de gênero em português. Toma-se como base teórica os estudos de Patrick Charaudeau (2013), no que se refere aos processos de construção de sentido, em diálogo com Marcos Bagno (1999) acerca do que se compreende por preconceito linguístico, considerando complementarmente aspectos de caráter discursivo, especialmente advindos da Teoria Dialógica do Discurso. A partir da análise conduzida, evidencia-se que o processo de transformação do fato noticiado ocorre com o apoio de saberes associados a crenças, que envolvem uma noção idealizada de língua. Considera-se que os processos de construção de sentido analisados são passíveis de causarem um efeito de verdade no telespectador, o que pode contribuir para a disseminação de posicionamentos ideológicos que propiciam o preconceito e a discriminação em relação às pessoas de identidade de gênero não-binária.
Realidade, experiência e discurso: repensando a noção sociossemiótica de contexto à luz de uma perspectiva vygotskiana
Authors: Abreu Diego Candido
Published: May 2024

O objetivo precípuo deste artigo é discutir a noção de contexto esposada pela Linguística Sistêmico-Funcional e, diante de seus problemas, propor o esboço de uma interpretação de contexto alternativa: o modelo trinitário de contexto. Tal conceituação tem como fundamento um diálogo entre a reflexão vygotskiana sobre a experiência como o eixo central da vida psicológica e a doutrina sociossemiótica acerca das variáveis contextuais (Halliday, 1994). Com esse objetivo em lente, após expormos os alicerces teóricos da Linguística Sistêmico-Funcional, discutiremos a definição de contexto advogada por essa escola. Em seguida, explicitamos os principais problemas e contradições da compreensão objetivista e superveniente esposada no modelo de representação da linguagem da Linguística Sistêmico-Funcional. Finalmente, ancorado nas reflexões de Vygotsky (1994) sobre a ideia de experiência (perezhivanie), defendemos o esboço do modelo trinitário de contexto, entendido como uma forma mais coerente de conceber os componentes extralinguísticos da linguagem em sua inter-relação com o significado e a materialidade da língua.

Published: May 2024

O artigo aborda o uso de expressões idiomáticas (EI) da língua portuguesa no Ensino Fundamental, 8º ano, em perspectiva semântica. Assim, buscou-se verificar textos veiculados nas redes sociais que apresentassem EI; selecionar variados tipos e gêneros textuais com EI; confrontar os fenômenos semânticos presentes nas EI selecionadas e sua relação com o conteúdo do Livro Didático (LD); e analisar criticamente os textos com EI. O corpus da pesquisa proveio do LD “Tecendo linguagens: língua portuguesa, 8º ano”, de Oliveira e Araújo (2018), adotado em escolas públicas situadas na Região Tocantina do Maranhão, além de postagens circulantes nas redes sociais. Nesse viés, realizou-se uma pesquisa de abordagem qualitativa e documental. Os autores que fundamentam o estudo são, entre outros, Xatara (1998), Biderman (2001), Ilari (2011) e Ferrarezi Jr. (2019). Com os resultados, constou-se, no LD, textos literários que contêm EI; no entanto, não é feita menção a elas, seja como conteúdo do LD ou quanto ao seu emprego em textos dispostos na obra analisada. Verificou-se também o uso de EI em postagens várias circulantes nas redes sociais. E, ao confrontar os textos veiculados na web com o conteúdo do LD, concluiu-se que não são exploradas, suficientemente, as EI no LD selecionado.

Este artigo analisa o conto “Sumidouro”, presente na obra Cumbe, uma narrativa gráfica de autoria de Marcelo D’Salete. Nesta análise, acompanho a trajetória de dor e de luta da protagonista Calu, uma mulher negra escravizada e violentada pelo poder patriarcal no contexto do Brasil colonial. Com uma abordagem decolonial e interseccional, pretendo demonstrar como a autoria reconfigura a imagem da mulher negra tantas vezes degenerada pelo racismo e pela presença do “mito da democracia racial brasileira” na literatura. Para tanto, verificarei o percurso das dores de Calu na escuridão do regime escravista e a sua subversão em luz e resistência que apontam para uma utopia forjada no seio da rebeldia negra.
A relação de afinidade entre brasileiros queer e língua inglesa: um discurso político e pedagógico
Authors: Pereira dos Santos Davi , Batista Martins de Morais João
Published: May 2024

O presente artigo objetiva investigar se existe uma relação entre língua inglesa e pessoas LGBTQIA+ brasileiras e qual poderia ser sua caus e possíveis efeitos. Utilizando como fundamentação, textos como os de Louro (1997), Santos (2019), Silva (2023) e Miskolci (2017; 2023) apresentamos uma discussão que envolve aspectos socioculturais, políticos e educacionais, por exemplo: como a língua inglesa pode interferir em questões de identificação e representatividade para as pessoas queer; mecanismos/agentes que promovem a língua inglesa; a importância das chamadas “divas do pop”; e a necessidade de refletir sobre o ambiente escolar enquanto espaço de contato entre diferentes pessoas de diferentes sexualidades e gênero, afetando diretamente a todos que ali circulam. Para tal, além do percurso teórico citado, realizamos uma pesquisa de campo com base no modo quanti-qualitativo por meio de um formulário, via Google Forms, contendo um questionário direcionado para pessoas de 17 a 30 anos que visava coletar suas percepções acerca de quesitos centrados em língua inglesa e sexualidade e, graças a este, obtivemos resultados que se aproximam de nossas hipóteses sobre o tema, atestando, principalmente, a grande influência da música para a relação analisada.
Verdade através da ficção na poética digital de E-imigrações
Authors: De Oliveira Gomes Marisa , De Oliveira Luizir
Published: May 2024

Os conceitos de verdade e ficção, ou realidade e invenção, ou até o uso da liberdade poética para florear acontecimentos, são discussões que permeiam a literatura desde antes do seu surgimento como tal. Neste artigo, busca-se analisar a obra literária digital E-imigrações, sob os conceitos de verdade através da ficção, de Davies (2016), aliado ao que é ficcional dentro de uma obra, de Iser (2002). Diferente do que se faz comumente com as obras digitais, em que se busca entender as diferenças de estrutura ou funcionamento, a análise aqui se faz no campo da essência do texto e os sentidos produzidos com o recurso da ficção. Ao fazer uso das ferramentas teóricas, a aplicação das mesmas revela que apesar das múltiplas possibilidades estruturais, as obras produzidas para a leitura no computador também fornecem material que mescla realidade, ficção e imaginário.
O realismo machadiano por trás das grades: reflexões realizadas com estudantes privados de liberdade, a partir do conto “Pai contra mãe” de Machado de Assis
Authors: Da Silva Sales Calado Magna Kelly
Published: May 2024

O presente artigo tem como objetivo relatar uma experiência da leitura e análise reflexiva do conto “Pai contra mãe” de Machado de Assis, que trata, principalmente, do período de escravidão no Brasil e em meio a esse cenário, aborda várias questões da natureza humana, como a luta pela sobrevivência e a ‘coisificação' do homem. Essas reflexões foram realizadas com estudantes em situação de reclusão[1], cujo propósito foi que experimentassem a literatura realista machadiana e fizessem uma analogia com o contexto no qual estão inseridos. Desse modo, serão apresentadas questões relacionadas ao modo como os estudantes “leram” o conto e de que maneira o que se vê nesse texto se vincula a sua condição de pessoa privada de liberdade, trilhando uma ótica empírica, estabelecendo um vínculo com aspectos sociais. As considerações serão apontadas numa articulação com a importância que teve o trabalho para a realidade em foco, intentando que essa literatura traz consigo marcas de ironia, num ímpeto de denúncia do passado humilhante que ainda necessita ser reparado. Características desse contexto são experimentadas no sistema prisional, segundo dados do CNJ (Conselho Nacional de Justiça) e IBGE (Instituto Brasileiro de Geografia e Estatística) devido não apenas à superlotação, mas marcas da escravidão que é possível verificar no cotidiano. As discussões direcionam para a relevância de leitura do texto literário em espaços de reclusão.
PALAVRAS-CHAVE: Leitura do texto literário. Educação de Jovens e Adultos. Sistema prisional

Paulo Freire, Diálogo e Empoderamento: O potencial libertador dos círculos de leitura literária, por adolescentes em condição de vulnerabilidade social
Authors: Vasco de Almeida Marcos Antonio , Pesce Lopes de Oliveira Priscila , Pesce Lucila
Published: May 2024

A partir dos conceitos freirianos de diálogo e empoderamento, o artigo discute como a leitura literária coletiva, por jovens socialmente vulneráveis, pode se constituir em educação como prática libertadora. O estudo teórico conceitual percorre três questões norteadoras. Os achados indicam que o fato de que os/as adolescentes das periferias estão mais vulneráveis a formas de preconceito, violência, bem como aos impactos negativos de políticas públicas ineficientes indica que se libertar dessa realidade implica um processo de construção e reconstrução da consciência coletiva. Quando leem, os/as adolescentes passam a ter condições de buscar autonomia, emancipação, autoafirmação e, sobretudo, promoção de seus saberes, pois a leitura permite um diálogo entre leitores/as, personagens literários e a materialidade histórica que os/as entorna. A leitura literária coletiva, dialógica, não prescritiva e fruidora apresenta condições favoráveis ao empoderamento do grupo, pois se constitui em prática crítica e reflexiva, através do pleno exercício da linguagem, que se converte em práticas sociais libertadoras. Desta forma, propor círculos de leituras aos/às jovens pode, além de formá-los/as crítica e reflexivamente, torná-los/as multiplicadores/as dessa práxis, ampliando a prática de leitura literária a um grupo cada vez maior de jovens.
