EDUCAÇÃO MEDIADA POR TECNOLOGIA EM UMA COMUNIDADE DE DIFÍCIL ACESSO NA AMAZÔNIA
Authors: Lubiana Alessandro
Published: May 2023

O Ensino Médio Mediado por Tecnologia (EMMT) é uma política implantada no ano de 2016 no estado de Rondônia. Neste modelo, os alunos se dirigem a uma escola, em qualquer local do estado, onde recebem aulas ao vivo, via satélite, ministradas por um professor que está em estúdio, e recebem o apoio de um professor presencial. Com a conclusão das primeiras turmas de EMMT, coube investigar as contribuições dessa política para os egressos de uma comunidade ribeirinha de difícil acesso na Amazônia, examinando as possibilidades de escolhas provocadas pela Educação Mediada por Tecnologia na percepção do egresso do Ensino Médio. A abordagem da pesquisa é qualitativa, baseada em entrevistas com questionário semiestruturados, os quais foram analisados por meio da análise do discurso de Bardin e da teoria da complexidade de Morin. Participaram oito egressos do ensino médio da escola General Osório, no distrito de Calama, que dista duzentos quilômetros da sede do município de Porto Velho, RO, e só é acessível por barco. Os resultados da pesquisa evidenciam que essa política pública, em lugares de difícil acesso, por meio das Tecnologias da Informação e Comunicação (TICs) na Educação oportunizou o ensino a comunidades remotas e contribui para que existam apropriações que possibilitam, na perspectiva de Kleine e Sen, escolhas aos egressos ao término do ensino médio que favorecem o seu desenvolvimento.

Published: May 2023

A Lei da Aprendizagem que está prevista na Consolidação das Leis do Trabalho (CLT) tem como objetivo criar oportunidades para que adolescentes e jovens, entre 14 e 24 anos, possam ingressar no mercado do trabalho. Ao mesmo tempo em que se propõe a assegurar uma formação integral ao aluno, ela intenciona qualificar a mão de obra, por meio das instituições formadoras. O presente artigo se propõe a investigar quem são os participantes do programa Aprendizagem Profissional em uma instituição formadora localizada na cidade de São Paulo. Trata-se de uma pesquisa de abordagem quantitativa de caráter explanatório. Foi constituída com a aplicação de um questionário com 25 perguntas fechadas e de múltipla escolha com base nos critérios do IBGE, considerando os grupos estatísticos sociais e multidomínio. Um dos critérios de seleção foi o período dos alunos no Programa, contemplando aprendizes na etapa inicial (de 1 a 5 meses), intermediária (7 a 10 meses) e final (13 a 16 meses), além da diversidade de idades. O estudo constatou diferença entre os aprendizes menores e maiores de 18 anos. Aqueles que ingressam precocemente no mercado de trabalho sofrem ainda mais com a injustiça social, pois possuem as casas mais populosas e mais que a metade tem uma renda familiar mensal de até dois salários-mínimos. Em geral, seus pais têm o nível de escolaridade inferior quando comparado aos pais dos alunos maiores. O ponto em comum entre eles é a busca de experiência profissional.

Published: May 2023

O presente artigo propõe compreender a atuação e a ressignificação do PROINFO no contexto da prática docente. O escopo principal dessa política volta-se à inserção e apropriação, na escola pública, dos artefatos tecnológicos que estruturam a sociedade conectada às redes digitais. Em meio a compreensão de que políticas não são meramente implementadas, mas colocadas em ação por sujeitos possuidores de convicções e interesses próprios. Sob a luz da teoria da atuação de Ball, Maguire e Braun (2016), propomos perceber a política do PROINFO atuada no contexto da prática. Para isso, foram realizadas entrevistas semiestruturadas com quatro professores de duas escolas públicas beneficiadas pelos laboratórios de informática do programa. Os resultados apontam que o PROINFO é encenado diante de circunstâncias que desafiam as ações dos docentes. A desatualização e número insuficiente de computadores para atender os alunos, bem como a desassistência pedagógica e técnica dificultam as atividades propostas no contexto da prática.

Authors: Yu Fanshan
Published: May 2023

Unmanned reconnaissance equipment has promoted the advancement of unmanned reconnaissance technology, but its rapid development has brought higher requirements for performance, cost, reliability, safety and other aspects. Among many evaluation methods, Analytic Hierarchy Process (AHP), Fuzzy Comprehensive Evaluation (FCE), and Multi-Attribute Decision Making (MADM) are widely used evaluation methods. AHP is a commonly used evaluation method, which has strong comprehensiveness and can fully consider index factors; FCE evaluates from different perspectives and has certain flexibility; MADM comprehensively considers the interrelationships and influences among indicators and can avoid the influence of individual experience factors of decision-makers. However, in practical applications, the evaluation results of a single method may be biased. This article summarizes and reviews the above evaluation methods. Firstly, it introduces the current development status of unmanned reconnaissance equipment. Then, it introduces various evaluation methods. Next, it introduces the application of unmanned reconnaissance equipment in different fields. Finally, it summarizes the advantages and disadvantages of various evaluation methods and prospects for the evaluation research of unmanned reconnaissance equipment. The aim of this article is to provide reference and inspiration for researchers in related fields.

L' artefice nel pensiero francescano
Authors: Salvestrini Amalia
Published: May 2023

La figura dell’artefice nel pensiero francescano è indice di una riflessione attorno al fare poietico spesso sviluppata attraverso l’analogia tra il creare divino e il produrre umano. La monografia, dopo una prima parte dedicata alla genesi della idea di artefice in fonti scritturistiche, filosofiche e retoriche, approfondisce la costituzione filosofica dell’idea di artefice nel pensiero di quattro frati Minori: Bonaventura da Bagnoregio, Pietro di Giovanni Olivi, Giovanni Duns Scoto e Guglielmo di Ockham. Nell’articolazione del processo poietico in progetto, opera e fruizione, si tratteggiano così le linee di tendenza e gli aspetti invarianti che, pur nella variazione significativa tra i diversi autori, portano a domandarsi, in conclusione, sulla possibilità di una “estetica francescana”.

Neglected Applications of Monolithic Structures: The Beginnings of Planar Chromatography with Mass Spectrometric Detection
Authors: Švec František
Published: May 2023

Thin layer chromatography (TLC) has been first reported by N. A. Izmailov and M. S. Schreiber in the late 1930s. The liquid mobile phase usually moves in pores of a layer supported by a rigid plate placed vertically in a simple container, e.g., a beaker. The flow is driven by capillary forces in the pores only and no sophisticated instrumentation is required. The individual components of the mixture are separated based on differences in their affinity for the solid stationary and the liquid mobile phases. The typical format of the stationary phase represents a thin layer coated on a glass, aluminium, or plastic plate. The porous sorbents can be silicon dioxide (silica), aluminium oxide (alumina), and cellulose, held together, e.g., with gypsum. The main advantages of TLC are the ease of carrying out the separations, which can also take place in parallel lines on the same plate, simple equipment, stationary phase for single use, static detection, and the possibility of archiving the separation result in a dried layer. However, the typical 100–250 μm thick layers are not well suited for combination of TLC with mass spectrometry (MS). This has led to the commercialization of ultrathin 10 μm thick monolithic silica layers. Unfortunately, their production was soon discontinued. Alternative solutions to that problem originated from the academic environment. In one approach, the layers were formed from nanofibers prepared by electrospinning. Alternatively, the layers were porous monolithic polymers produced by polymerization in situ and a variety of separations of both small and large molecules was demonstrated. The use of MS detection then enabled determination of molecular mass of the compounds in the separated spots. Although preparation of the thin monolithic layers originally appeared straightforward, some unexpected problems had to be solved. This review details issues related to the history of the monolithic TLC and presents approaches leading to well behaving layers suitable for the desired separations.

The Batu Kalde Site is a ruin of Hindu Temple in Pangandaran, West Java, Indonesia. Despite it has been reported since 1915 and subsequently studied by several archaeological teams, a lot of aspects including geoarchaeology of this temple are still unrevealed. This preliminary study was an overview of general aspects of geoarchaeology of the temple. The result shows that the temple was constructed before the 14th century by a population of farmers and fishermen lived on the fertile coastal plain of Pangandaran in south coast of Java Island. The temple was constructed in a narrow coastal plain of a small island on a Quaternary marine sediment offshore of the present Pangandaran coast. The existing tombolo morphology of Penanjung has not been completely formed when the temple was being constructed. The temple was constructed using bedded sandstone of the Pamutuan Formation quarried from outcrops in the vicinity of the temple. This study shows that utilization of materials from local available resource might have been a model of temple construction within the classical period in the period of between the 7-14th century in West Java, Indonesia.
An epidemic model for control and possible elimination of Lassa fever
Authors: Ayoade Abayomi , Nyerere Nkuba , Ibrahim Mohammed
Published: May 2023

Lassa fever is a deadly viral disease whose incubation period ranges from six to twenty-one days and about eighty percent of Lassa virus infection is asymptomatic. A deterministic model was formulated to quantify the transmission dynamics of the disease under isolation and treatment of the isolated asymptomatic and symptomatic humans for effective management and possible elimination of the disease. The solutions of the model were shown to be positive and bounded. Equilibrium analysis was conducted and both the disease-free and the endemic equilibria were derived. The threshold quantity for disease elimination , $R_{0}$ , was also obtained and used to derive conditions for the existence of stability of the eqilibria. The quantity was also employed to examine the sensitivity of the model parameters to disease propagation and reduction. The theoretical analysis was then complemented with the quantitative analysis by adopting a set of realistic values for the model parameters in order to show the effect of isolation and treatment on the spread and fatality of Lassa fever. Results from the quantitative study showed that death and infection from Lassa fever fell continuously as more and more exposed individuals were detected and isolated for treatment. The study therefore suggested that any measure taken to eradicate or curtail Lassa fever spread should include detection and isolation of the exposed humans for prompt treatments.

Viviografia: Conceito teórico-metodológico para pesquisas narrativas
Authors: Lemos Silva Novo Pinheiro Laís , Amaral da Fontoura Helena
Published: May 2023

O presente artigo tem por principal objetivo elucidar um conceito teórico-metodológico insurgente em potencial no âmbito das pesquisas narrativas, resultado de um estudo de doutoramento no campo da Educação. Para tanto, são consideradas as contribuições de Fontoura, Josso, Cosson entre outros, a fim de colaborar para maior inteligibilidade da Viviografia desenvolvida por Pinheiro. Ao problematizar a pesquisa acadêmico-formal, buscamos demonstrar as potencialidades de referências advindas de vivências, as chamadas referências viviográficas, um embasamento por experiência de vida, por meio de narrativas de memórias inspiradas pelo literário. Alguns itinerários metodológicos, como Círculos de leitura e oficinas artístico-literárias como a Viviossonografia, que envolve narrativas de vida a partir da música, são essenciais para o desenvolvimento da Viviografia. A Tematização de Fontoura e o Diário viviográfico também são importantes metodologias na construção de uma pesquisa narrativa de cunho viviográfico. Defendemos, portanto, uma pesquisa que valorize as contribuições de seus colaboradores, de modo a representá-los de forma corpórea textualmente. Esperamos, com este trabalho, abrir leques de possibilidades nas pesquisas narrativas que busquem dialogia efetiva e processos autorais emancipatórios.

Published: May 2023

O presente texto é fruto de uma pesquisa de Mestrado em Educação da Universidade de Uberaba (Uniube) vinculado à linha de pesquisa Desenvolvimento Profissional, Trabalho Docente e Processo de Ensino-Aprendizagem. Buscamos, por meio da pesquisa, defender um espaço de Educação Infantil com propostas didáticas que levem em consideração:  a brincadeira, a criatividade e a linguagem. Ao aprofundarmos na temática,   compreendemos que é preciso romper com a dualidade do vir a ser e do assistencialismo, reconhecendo a criança como “sujeito de direitos”, considerando as suas  condições e as particularidades do psiquismo. Desta maneira, o presente texto tem como objetivo evidenciar a importância da brincadeira, da linguagem e da criatividade no contexto da Educação Infantil, com aporte teórico da perspectiva Histórico-Cultural. A pesquisa bibliográfica e documental  buscou, por meio de fichamentos de leituras, organizar quadros, tabelas, resumos, anotações pessoais e assim estabelecer relações entre a tríade: linguagem, brincadeira, criatividade e contribuir com propostas didáticas para a Educação Infantil considerando a legislação vigente. Concluimos que os princípios da Teoria Histórico-Cultural contribuem para uma prática intencional que valoriza a infância em suas diferentes linguagens, reconhecendo uma ação intervencionista e o respeito às singularidades.

A violação dos direitos humanos de professores universitários na ditadura civil-militar: Um estado da arte
Authors: Candido Rivaldo Dionizio , Dudeque Pianovski Vieira Alboni Marisa
Published: May 2023

O período de 1964 a 1985, no Brasil, caracteriza-se pelo rompimento da institucionalidade do país, com a instalação de uma ditadura civil-militar que perpetrou graves violações de direitos humanos, com a supressão de direitos civis e políticos e o uso de força violenta do Estado. A comunidade acadêmica, nesse contexto, foi atingida por essas ações repressoras. O presente artigo, portanto, tem como objetivo analisar teses e dissertações que discutem a violação de direitos humanos de professores universitários durante a ditadura civil-militar no período 2017-2022. Para tanto, foram selecionados trabalhos disponíveis no Banco de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) que discutem a interface entre (violação dos) direitos humanos, ditadura civil-militar e educação. A pesquisa, do tipo estado da arte, permitiu levantar e discutir as últimas produções acadêmicas da área, bem como identificar lacunas a serem exploradas. Foram selecionados 13 trabalhos, dos quais se discutiram suas particularidades, entre elas as diferentes nomenclaturas utilizadas pelos estudos para se referir ao período de 1964 a 1985, os significados atribuídos à violação dos direitos humanos e sua relação com a educação. Os resultados evidenciaram a presença da discussão em diferentes áreas do conhecimento, mas, ao mesmo tempo, baixa produção acadêmica na área da educação sobre a temática estudada.
Post-processing in multi-material 3D printing
Authors: Brancewicz-Steinmetz E. , Sawicki J.
Published: May 2023

This study aims to investigate the adhesion of combining two materials with different properties (PLA-TPU and TPU-PLA) printed in FFF (fused filament fabrication) with post-processing treatments.The scope of the study includes making variants of samples and subjecting them to three different post-printing treatments. After processes, shear tests were conducted to determine the adhesion.The post-printing treatment results in a stronger inter-material bond and increased adhesion strength; the best average shear strength results were achieved for annealing without acetone and for PLA/TPU samples for treatment in cold acetone vapour.In the study, adhesion was considered in the circular pattern of surface development.Reinforcement of the biopolymer broadens the possibilities of using polylactide. Examples of applications include personalised printing items, where the elastomer will strengthen the polylactide.These studies aim to promote the use and expand the possibilities of using PLA biopolymer. The strength properties of printouts from different materials are often insufficient, hence the proposal to use post-printing processing.
Guerra de Malvinas: contrainsurgencia, desprofesionalización defensiva y derechos humanos
Authors: Winer Sonia , Guerrero Iraola Jerónimo
Published: May 2023

El artículo analiza los efectos del adoctrinamiento en guerra revolucionaria y doctrina de seguridad nacional a partir de la guerra de Malvinas, poniendo el foco en las consecuencias de la introducción de la hipótesis “ideológica” de conflicto y en la división mundial de roles y funciones asignadas a las Fuerzas Armadas por las potencias imperiales durante la bipolaridad.  En esta línea, aborda dos aspectos o dimensiones de las mismas vinculadas entre sí: por un lado, respecto de la desprofesionalización de la defensa argentina y de su impericia para cuidar soberanía; por el otro, en materia de la vulneración de derechos humanos y prácticas de tortura sobre soldados conscriptos producidas durante el conflicto bélico ocurrido en el Atlántico Sur.
Los partidos políticos argentinos y las negociaciones por las Islas Malvinas, 1982- 2022: de consensos y vaivenes
Authors: Míguez María Cecilia
Published: May 2023

Este artículo analiza las posiciones de los partidos políticos mayoritarios de la Argentina, en su rol de oficialismo y oposición, respecto del reclamo de la soberanía por las Islas Malvinas. En una primera instancia estudia cómo radicalismo y justicialismo se convirtieron desde finales de la década de 1980 y durante 1990 en los artífices de la reforma del estado, de la liberalización, de la consolidación del endeudamiento, y también, de la desmalvinización. Luego retoma las transformaciones operadas a partir del siglo XXI, cuando durante los gobiernos del Frente para la Victoria, la cuestión Malvinas logró instalarse como causa latinoamericana, y reformularse políticamente a nivel interno y global. Finalmente analiza los vaivenes de los últimos gobiernos, el de la Alianza Cambiemos (2015-2019) y el actual de Alberto Fernández. En síntesis, lo que este artículo busca demostrar, es cómo los vaivenes de la política internacional y de la política exterior respecto de la soberanía de las Islas Malvinas entre 1982 y 2022 reflejan una Argentina intensamente disputada, donde el rumbo de la política económica y de la inserción internacional son objeto de grandes debates.
Qué es Contabilidad
Authors: Arreghini Hugo Ricardo
Published: May 2023

El trabajo trata de mostrar si la Contabilidad es una disciplina que se reconoce como objeto.En busca de una respuesta respaldada por el juicio de los que han investigado en procura de encontrar la definición sobre esa discutible materia, quien lo intenta se encuentra ante una gran variedad de opiniones diversas.Las respuestas que se obtienen difieren entre calificar a la Contabilidad como una ciencia pura o aplicada, una técnica o una tecnología, un arte o un instrumento para explicar la consecución de un objeto.El resultado de la tarea reconoce a la Contabilidad el papel de informar a la persona – natural o ideal – sobre las consecuencias financieras periódicas de administrar la entidad económica – empresa – que creó para desarrollar esa actividad.
Encuadramiento teórico de la contabilidad de gestión como segmento de la teoría general de la contabilidad
Authors: Tamagno Mario Raúl
Published: May 2023

La Contabilidad ha ido consolidándose, a través de distintos estudios e investigaciones que han derivado en Teorías y Corrientes. Transformándose así, desde una técnica hacia modelos científicos, nutriéndose de otras ciencias: principalmente de la economía, la administración, la sociología y la psicología. Sus objetivos fueron evolucionando desde el registro de la realidad patrimonial hacia la explicación de la realidad, e incluso su predicción y, de esa manera, interviniéndola.
La demanda de información interna para la toma de decisiones ha sido cada vez mayor, lo que ha generado un estudio denominado Contabilidad de Gestión. Pretenderemos analizar su importancia relativa, así como las distintas teorías y corrientes que le han impactado.
Se ha logrado proponer un encuadramiento de la Contabilidad de Gestión dentro de la Teoría General de la Contabilidad.
El estudio de la Contabilidad de Gestión a través de las distintas teorías contables nos permite observar la importancia que tiene la disciplina o segmento contable como generadora de información que apuntale la gestión estratégica de las empresas.
Un ejemplo, de esta evolución, es el de la administración estratégica de costos, donde el uso de la información de costos permite desarrollar e identificar estrategias más adecuadas que producirán una ventaja competitiva sustancial.
Seminal prolactin is associated with HSP90 transcript content in ejaculated spermatozoa

Objective: Evidence indicates that an imbalance between the production of reactive oxygen species and defense ability of antioxidants has clinical significance in the pathophysiology of male infertility. To investigate the role of seminal prolactin (PRL) in the fertilizing capacity of men, the present study evaluated the associations of seminal PRL levels with semen parameters and heat shock protein 90 (HSP90) transcript abundance in ejaculated spermatozoa.Methods: We assessed seminal PRL levels and the abundance of HSP90 transcripts in ejaculated spermatozoa from normozoospermic donors (n=18) and infertile men (n=18). The transcript content of HSP90 in ejaculated spermatozoa was analyzed using real-time polymerase chain reaction.Results: Seminal PRL concentrations in infertile patients were significantly lower (p=0.004) than in fertile controls. Seminal PRL showed relatively good diagnostic power for discriminating infertile men (area under the curve=0.776; 95% confidence interval, 0.568 to 0.934; p=0.005). Significant positive correlations were seen between seminal PRL levels and sperm count (r=0.400, p=0.016) and progressive motility (r=0.422, p=0.010). Infertile patients showed a significantly higher abundance of sperm HSP90 than fertile controls (p=0.040). Sperm HSP90 transcript abundance was negatively correlated with sperm progressive motility (r=0.394, p=0.018). Men with higher seminal PRL levels exhibited a lower abundance of sperm HSP90 transcripts.Conclusion: Our finding demonstrated associations among semen quality, seminal PRL levels, and the abundance of HSP90 transcripts in ejaculated spermatozoa. Seminal PRL may contribute to male fertility by maintaining the seminal antioxidant capacity and may have the potential to act as a diagnostic and prognostic biomarker.
Story Beyond the Eye: Glyph Positions Break PDF Text Redaction
Authors: Bland Maxwell , Iyer Anushya , Levchenko Kirill
Published: May 2023

In this work we find that many current redactions of PDF text are insecure due to non-redacted character positioning information. In particular, subpixel-sized horizontal shifts in redacted and non-redacted characters can be recovered and used to effectively deredact first and last names. Unfortunately these findings affect redactions where the text underneath the black box is removed from the PDF.
We demonstrate these findings by performing a comprehensive vulnerability assessment of common PDF redaction types. We examine 11 popular PDF redaction tools, including Adobe Acrobat, and find that they leak information about redacted text. We also effectively deredact hundreds of real-world PDF redactions, including those found in OIG investigation reports and FOIA responses.
To correct the problem, we have released open source algorithms to fix vulnerable redactions and reduce the amount of information leaked by nonexcising redactions (where the text underneath the redaction is copy-pastable). We have also notified the developers of the studied redaction tools. We have notified the Office of Inspector General, the Free Law Project, PACER, Adobe, Microsoft, and the US Department of Justice. We are working with several of these groups to prevent our discoveries from being used for malicious purposes.
