Authors: Du Wenfeng , Wang Hui , Zhu Liming , Zhao Yannan , Wang Yingqi , Hao Runqi , Yang Mijia
Published: September 2021

Aiming at the problems of a low material utilization rate and uneven stress distribution of cast-steel support joints in cable dome structures, topology optimization and additive manufacturing methods are used for optimization design and integrated manufacturing. First, the basic principle and calculation process of topology optimization are briefly introduced. Then, the initial model of the support joint is calculated and analyzed by using the universal software ANSYS Workbench 2020R2 and Altair OptiStruct, and the optimized joint is imported into Discovery Live to smooth the surface. The static behaviors of three types of joints (topology-optimized joints, joints after the smoothing treatment, and joints from practical engineering) are compared and analyzed. Finally, the joints are printed by using fused deposition modeling (FDM) technology and laser-based powder bed fusion (LBPBF) technology in additive manufacturing. The results show that the new support joint in the cable dome structure obtained by the topology optimization method has the advantages of a novel shape, a high material utilization rate, and a uniform stress distribution. Additive manufacturing technology can allow the manufacture of complex shape components with high precision and high speed. The combination of topology optimization and additive manufacturing effectively realizes the advanced design and integrated manufacturing of support joints for cable dome structures.
Anhysteretic Magneto-Elastic Behaviour of Terfenol-D: Experiments, Multiscale Modelling and Analytical Formulas
Authors: Daniel Laurent , Domenjoud Mathieu
Published: September 2021

Giant magnetostrictive materials such as Terfenol-D and Galfenol are used to design actuators and sensors, converting magnetic input into a mechanical response, or conversely, mechanical input into a magnetic signal. Under standard operating conditions, these materials are subjected to stress. It is therefore important to be able to measure, understand and describe their magneto-mechanical behaviour under stress. In this paper, a comprehensive characterisation of the anhysteretic magneto-mechanical behaviour of Terfenol-D was performed. An energy-based multiscale approach was applied to model this behaviour. Finally, it was shown that the strain behaviour of Terfenol-D can be satisfactorily described using an analytical model derived from the full multiscale approach.

Published: September 2021

Fabrication of complete dentures (CDs) utilizing computer-aided design and computer-aided manufacturing (CAD/CAM) methods has attracted a lot of attention. The purpose of this paper was to summarize current knowledge about digital CDs and the relevant technology, and to present the application of the new technology in a dental geriatrics case. Initially, some of the challenges regarding digitization of the oral mucosa as a supporting surface of the CDs’ intaglio surface are listed. Next, a brief introduction of the CAD software capabilities regarding CDs is presented. The latest CAM additive and subtractive techniques for CDs are following. Subsequently, the consecutive steps for the construction of a digital CD as part of the prosthodontic treatment of a 90-year-old ambulative female patient are presented. Finally, some considerations about the digital workflow in CD manufacturing are discussed. In conclusion, the new digital technology has clear advantages; however, implementation requires careful planning. The digital workflow is applicable and versatile.
Handlebar Robotic System for Bimanual Motor Control and Learning Research
Authors: Cardoso Lucas R. L. , Pedro Leonardo M. , Forner-Cordero Arturo
Published: September 2021

Robotic devices can be used for motor control and learning research. In this work, we present the construction, modeling and experimental validation of a bimanual robotic device. We tested some hypotheses that may help to better understand the motor learning processes involved in the interlimb coordination function. The system emulates a bicycle handlebar with rotational motion, thus requiring bilateral upper limb control and a coordinated sequence of joint sub-movements. The robotic handlebar is compact and portable and can register in a fast rate both position and forces independently from arms, including prehension forces. An impedance control system was implemented in order to promote a safer environment for human interaction and the system is able to generate force fields, suitable for implementing motor learning paradigms. The novelty of the system is the decoupling of prehension and manipulation forces of each hand, thus paving the way for the investigation of hand dominance function in a bimanual task. Experiments were conducted with ten healthy subjects, kinematic and dynamic variables were measured during a rotational set of movements. Statistical analyses showed that movement velocity decreased with practice along with an increase in reaction time. This suggests an increase of the task planning time. Prehension force decreased with practice. However, an unexpected result was that the dominant hand did not lead the bimanual task, but helped to correct the movement, suggesting different roles for each hand during a cooperative bimanual task.
Simultaneous Separation and Analysis of Five Compounds in Cibotium barometz by Micellar Electrokinetic Chromatography with Large-Volume Sample Stacking
Authors: Wang Lili , Xu Huifeng , Yu Lishuang , Zhu Zaishi , Ye Hongzhi , Liu Linglong , Li Xihai , Peng Jun
Published: September 2021

A large volume sample stacking (LVSS) method in micellar electrokinetic chromatography (MEKC) with diode array detector was developed for the simultaneous separation and analysis of five compounds: protocatechuic acid, protocatechuic aldehyde, caffeic acid, syringetin and vanillin in Cibotium barometz. The electrophoretic separation was performed in a 10 mM sodium dodecyl sulfate (SDS) and 50 mM sodium borax-sodium dihydrogen phosphate system (pH = 8.5) with 10% methanol at a separation voltage of 30 kV after optimizing the typical parameters. The detection limits were from 32 pg to 65 pg, which were around 12–27 times lower than MEKC, and 500 times less than reported methods. Finally, the established method was validated to be applicable for the determination of protocatechuic acid and caffeic acid in Cibotium barometz. This proposed method is expected to facilitate the quality control of Cibotium barometz.
Redefining Goods Movement: Building an Ecosystem for the Introduction of Heavy-Duty Battery-Electric Vehicles
Authors: Fenton Dawn , Kailas Aravind
Published: September 2021

This article reviews the Volvo Low-Impact Heavy Green Transport Solution (LIGHTS) project, a multifaceted public–private partnership in Southern California, and provides some early insights and a model for successful fleet adoption of Class 8 battery-electric trucks. This paradigm shift in commercial trucking is emerging, forcing greater interdependence among many stakeholders—fleets, truck manufacturers, and policymakers—not currently engaged in the traditional heavy-duty commercial truck market. The many perspectives from this article such as lead times and costs associated with the deployment of charging infrastructure, developing the workforce to support largescale deployments, and the need for market development incentives from the government can be used to inform the programs and policies of California and other states seeking to follow their lead.
The healthy/unhealthy worker effect as a phenomenon of occupational selection and the causation problem
Authors: Babanov Sergey Anatolievich
Published: September 2021

Today, the "healthy worker effect" is understood as organized (on the part of the employer) and/or unorganized (self-selection on the part of the worker, due to the functional capabilities and the state of workers’ health) professional selection of healthier workers in unfavorable working conditions, who remain in the profession. It represents one of the most important problems in epidemiological research in occupational medicine. The “healthy worker effect” and its intensity in various industries (in various professions) can indirectly characterize the harmful and unfavorable conditions. The “healthy worker effect” and its intensity determine the need for medical and social security, as well as rehabilitation measures, not only for people who remain in this production (in this profession), but also for people who left this production or specialty, to prevent the phenomenon of increased mortality among workers who left a given production or profession due to suspension from work based on the results of periodic medical examinations and self-selection, or due to intolerance to working conditions because of the state of health.
Possibilities of recombinant cytokines in the structure of training of highly qualified athletes
Authors: Alpatov S.P.
Published: September 2021

Serious sports achievements are associated with extreme impacts on the human body: psycho-emotional and physical loads of the training period, competitions requiring the mobilization of all the adaptive reserves of the body, changes in climatic conditions when athletes move long distances, adverse environmental factors leading to hypothermia. The combination of these factors has a depressing effect on the immune system. The emergence of immune disorders in athletes during periods of extreme physical and psycho-emotional stress made it possible to identify the mechanisms of adaptation failure and depletion of immunity reserves, which requires corrective measures. Roncoleukin® is a complete structural and functional analogue of endogenous interleukin-2 (IL-2) and has the same spectrum of functional activity. It is able to compensate for the deficiency of IL-2 and reproduce its effects as one of the key components of the cytokine network.

Free radical peroxidation and natural antioxidants
Authors: Gizinger Oksana Anatolievna , Dadali V. A.
Published: September 2021

Modern food products provide no more than 5-6% of the body's need for micronutrients, many of which are antioxidants. The current state of the problem of nutritional deficiency predetermines a chronic long-term deficiency of antioxidants in the diet. Providing the body with balanced polyvalent antioxidant complexes and normalizing its antioxidant status is the basis of health and active longevity.

Authors: Gizinger O.A.
Published: September 2021

The article analyzes the role of fatty acids in the life support processes of the organism. For some short- and medium-chain fatty acids, the ability to inactivate a number of microorganisms, in particular Helicobacter pylory, has been shown. Information on the role of ω-6 polyunsaturated acids of the arachidonic and docosahexaenoic family in the structural and functional development of the nervous system has been presented. The materials presented in the article expand the understanding of the role of lipids in metabolic processes and dictate the need to continue the study of lipids as the main energy substrates, sources of plastic material, structural components of erythrocyte membranes, nervous tissue, and skeletal muscles.
The role of antimicrobial defense factors in the pathogenesis of immune disorders in deviated septum. Part 2
Authors: Kornova Natalya Viktorovna
Published: September 2021

The article presents the data from Russian and foreign researchers on the state of humoral and cellular factors of antimicrobial protection of the mucous membrane of the nasal cavity and paranasal sinuses in the pathogenesis of immune disorders in deviated septum. One of the factors affecting the intensity of the inflammatory reaction and the rate of epithelialization of the mucous membrane is a decrease in IL-10 receptor expression, and, as a consequence, a decrease in its endogenous production. In vivo experiments have shown that the reduced expression of genes responsible for the synthesis of interleukin-10 inhibits infiltration of the wound postoperative surface of phagocytes, reducing the expression of CC-chemokines (MCP-1, MIP-1α), their receptors, cytokines, and interleukin-1α. The role of cellular and humoral factors, interreceptor interactions of cells of the respiratory, glandular epithelium, phagocytes, and lymphocytes in pathological conditions of the nasal mucosa and paranasal sinuses was analyzed. The role of immune mechanisms in the development of pathological reactions in deviated septum is shown. The presented review will expand the understanding of the role of antimicrobial factors in the pathogenesis of immune disorders in deviated septum.
Formation of emotional stability of citizens 65+ in a pandemic COVID 19 (part 2)
Authors: Krylov Aleksandr Petrovich
Published: September 2021

The problem of emotional stability of citizens 65+ is sharply expressed in the context of a pandemic and forced self-isolation. The restrictions introduced in connection with the quarantine for coronavirus infection reduced social activity and reduced the possibility of receiving face-to-face psychological assistance for people aged 65 and over. Most of those elderly aged 65+, who had few contacts with loved ones and society earlier, before the pandemic, have become even more alienated from active social life. For social organizations that provide assistance to the elderly, it is necessary to formulate programs and provide certain services for implementation, helping to overcome the current situation in society and not being limited to the delivery of food and medicine. Emotional instability in the elderly should be overcome by a timely set of rehabilitation measures, regular examinations by a general practitioner and, if necessary, by doctors of other specialties.
Immunoprophylaxis. Its role in sports medicine
Authors: Starikov I.E.
Published: September 2021

Achieving high results in sports directly depends on the biological characteristics of the athlete’s body and the state of his health, which, in turn, is determined by the adequate functioning of the integrative systems of the body: immune, endocrine and nervous. At the same time, modern sport is associated with the presence of many factors that adversely affect the state of the athlete’s immunity. These include physical activity that is on the verge of a person’s physiological capabilities, states of extreme psychological stress, changes in climatic-zone conditions when moving athletes over long distances, unfavorable environmental factors leading to hypothermia (the same stress). A decrease in the activity of the immune system leads to the emergence of immune dysfunctions, as a result of which the risk of the occurrence of infectious colds and exacerbation of chronic pathology significantly increases. The presence of these facts indicates the need for the prophylactic use of immunotherapy.
Laboratory strategies for the diagnosis of COVID 19
Authors: Ivanova T.V.
Published: September 2021

To prevent further spread of the COVID 19 pandemic, rapid and accurate diagnosis of the infection is essential. The standard method for detecting coronavirus is polymerase chain reaction. Serological methods and tests for detecting antibodies against SARS-CoV-2 and determining protective immunity in the population are usually used to retrospectively identify those patients who have already suffered an asymptomatic and mild form of infection. Immunological monitoring is necessary to control the situation of infection in patients at the hospital and pre-hospital stages, in order to track contacts and conduct epidemiological surveillance of the situation with the spread of the SARS-CoV-2 virus

Authors: Selamoglu Melis , Erbas Bircan , Kasiviswanathan Karthika , Barton Chris
Published: September 2021

Background

Electronic cigarettes (e-cigarettes) are being marketed to people who smoke (PWS) as a smoking cessation aid. GPs have an important role in providing patients with support to encourage them to quit smoking. The emergence and marketing of e-cigarettes as a smoking cessation alternative poses challenges to GPs in advising and supporting PWS to quit.

Aim

This systematic review aims to synthesise available evidence on the knowledge, attitudes, and perceptions of GPs about e-cigarettes as a smoking cessation aid.

Design & setting

Mixed-methods study review including quantitative, qualitative, and mixed-methods studies of GPs in primary care settings.

Method

MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), Scopus, PsycINFO, and Embase databases will be searched to identify articles published between 1 January 2003 and 30 June 2021. A Google search will be conducted to identify grey literature. Two independent reviewers will screen abstracts for relevance and full-text studies. Articles will be appraised for quality using the Mixed Methods Appraisal Tool (MMAT) and a Preferred Reporting Items for Systematic Reviews, and Meta-Analysis (PRISMA) diagram will illustrate the flow of articles and reasons for exclusion. An evidence synthesis method will be employed and guided by the Theory of Planned Behaviour (TPB). A descriptive qualitative synthesis of the findings will be reported.

Conclusion

Findings will provide a synthesis of current evidence regarding the knowledge, attitudes, and perceptions among GPs of e-cigarettes as a smoking cessation aid. This information will be useful to guide future research on the needs of GPs in advising and supporting patients to quit smoking. It will also assist in the development of health policy and guidelines on the role and place of e-cigarettes as a smoking cessation aid.
performance de Sia:
Authors: Santana Bárbara Melissa , Barchi Paglione Marcela
Published: September 2021

O presente trabalho se propõe a analisar a performance verbivocovisual da cantora Sia no programa televisivo The Ellen DeGeneres Show (2014) no que concerne às valorações socioculturais imbricadas na representação desse sujeito. A partir da Filosofia da Linguagem do Círculo B.M.V. (Bakhtin, Medvíedev, Voloshínov) utiliza-se os conceitos de sujeito, ideologia, diálogo e arquitetônica, bem como a noção de verbivocovisualidade (PAULA; SERNI, 2017). Há como objetivo refletir sobre os conflitos ideológicos demarcados na performance da artista, como a afronta à indústria do entretenimento e a objetificação do corpo da mulher. De acordo com a metodologia analítico-descritiva, parte-se das materialidades enunciativas para os aspectos transliguísticos do discurso. Espera-se, a partir da discussão proposta, apontar como se configuram os embates ideológicos refletidos e refratados na performance de Sia e, assim, contribuir para os estudos sobre a construção sociocultural do sujeito na episteme bakhtiniana.

Authors: CORDEIRO ALLAN
Published: September 2021

ABSTRACT

 

This paper examines the implications of interaction in foreign language learning and foreign language teaching. It intends to contribute to the discussion about the importance of interaction in and out of the classroom. Two papers were chosen to support the work on similar topics. The Task-based Language Teaching (TBLT) is presented alongside Stephen Krashen’s hypothesis as well as the Input Hypothesis. Analyses and observations are exposed to both papers. The concept of interaction and its relevance in learning foreign languages followed by the importance of tasks in the interactional process will be addressed. Paiva’s ecological relation and how she relates it with the classroom environment and Jauregi’s interactional analysis will also be presented. Lastly, the work considers the human-machine interaction and the digitalization of language learning and teaching. Jauregi’s research on Second Life interactions is also analysed alongside the importance of blended learning. The analysis confirms the importance of interaction in learning foreign languages. It is the essence of communication which is the primary function of languages.

ensino de língua de portuguesa para os sujeitos da educação básica paranaense
Authors: Da Silva Fontana Larissa
Published: September 2021

Neste trabalho, cujo aporte teórico se dá na teoria da História das Ideias Linguísticas, objetivo investigar quais os efeitos de sentido construídos acerca do papel da escola e dos sujeitos da escola veiculados pelas Diretrizes Curriculares da Educação Básica (DCEs) do Estado do Paraná para o ensino de Língua Portuguesa. Para isso, analiso alguns trechos do documento que debatem as relações entre escola-estudante de classe marginalizada e/ou escola-língua-estudante de classe marginalizada. Ao problematizar os campos de significação que se materializam no documento acerca dessas relações, discuto como a escola é colocada como a única oportunidade de os alunos das “classes marginalizadas” – encarados como um outro despossuído de voz e de capacidade de agir criticamente sobre a sociedade – ascenderem socialmente. Nesse processo de “emancipação”, a relação com a língua portuguesa se dá de maneira necessariamente corretiva já que o objetivo é possibilitar aos estudantes socialmente marginalizados o acesso a variante socialmente prestigiada, falada pelas classes privilegiadas. Esse contato, que silencia a diversidade cultural, linguística e social dos estudantes, é regido e controlado pelo Estado que se faz constantemente presente ao longo do documento, mesmo que de forma implícita.
inter-relação entre papel social e posição na manifestação do conflito interacional
Authors: Pacheco Roberta Fernandes , Silva Müller Alice
Published: September 2021

Este artigo tem o objetivo de analisar como as posições associadas a papéis sociais manifestados em uma entrevista política geram conflito no curso da interação. Ancorado nos estudos sociointeracionais da Linguística, o artigo opera com a relação teórica entre papel social, posição e conflito, apoiando-se, dentre outros, em Weizman (2008), XXX (2018a) e Haugh e Sinkeviviute (2018, 2019). A entrevista analisada é derivada do programa Roda Viva da TV Cultura, transmitida ao vivo em 30/07/2018, tendo como entrevistado o então candidato à presidência Jair Bolsonaro. Essa entrevista compõe o corpus do projeto de pesquisa XXX que conta com mais quatro entrevistas do referido programa, abrangendo diversos cenários políticos no Brasil ao longo dos últimos vinte anos. A partir de uma abordagem qualitativa e interpretativa, a análise evidencia que as posições, associadas a papéis sociais, são disputadas interacionalmente, através de sequências de conflito perpassadas por estratégias interacionais como acusações e discordâncias.
pressuposição em manchete e a leitura crítica em foco
Authors: Perobelli Roberto , Da Silva Correia Bianca
Published: September 2021

Neste artigo discutimos a respeito do uso da pressuposição em manchetes de jornais e fazemos considerações sobre a importância do estudo desse fenômeno para formação do leitor crítico. Neste sentido, apresentamos uma classificação de acionadores de pressuposição nas manchetes principais da capa do Jornal Folha de S. Paulo referente aos primeiros 30 dias da pandemia de COVID-19, com a finalidade de ampliar as possibilidades de posicionamento crítico diante de um texto, considerando seus contextos e ferramentas de produção, por se tratar de um requisito importante para o aprimoramento das práticas de letramento no contexto escolar. Os resultados apontam que os tipos de pressupostos encontrados se dispõem em um contínuo que varia em grau de implicitude.
Atenção, multitasking e compreensão leitora: relacionando conceitos
Authors: Steigleder Gomes Graziella , Paz Pereira Ana Karina , Casagrande Rosso Aline
Published: September 2021

O presente artigo tem por objetivo relacionar noções sobre atenção às formas como essa se entrelaça aos processos concernentes a multitasking e compreensão leitora, de modo a iluminar facetas sobre como esses ocorrem. Para tanto, procedemos a uma breve revisão de literatura. Os dados encontrados indicam que, se, por um lado, o desempenho em testes de leitura de multitaskers e sujeitos não engajados em tarefas secundárias é semelhante, há relativo custo para a compreensão leitora, se considerado o tempo maior que os primeiros precisam para decodificar os textos, quando comparados com os indivíduos que não estão atuando sob atenção dividida. Tais achados apresentam evidências que podem ser determinantes na escolha de procedimentos pedagógicos que levem em conta o ato de ler concomitantemente a outra tarefa, especialmente se essa for relacionada a mídias, como mensagens instantâneas encontradas em aplicativos, bem como à navegação na internet.
Considerações sobre práticas de letramento em inglês em um colégio público
Authors: Arruda Silveira Paulo Henrique
Published: September 2021

Este trabalho tem por objetivo observar se existe consonância entre o que é ofertado por um colégio público com relação à disciplina de Inglês e as práticas de letramento não escolares dos estudantes, buscando-se averiguar: a) até que ponto os letramentos escolares valorizados nesse contexto dialogam com o modo como os alunos utilizam a língua nas suas práticas sociais e b) em que medida a menor ou maior proximidade entre letramentos não escolares e escolares pode influenciar o processo de aprendizagem. Para tal fim, usou-se o arcabouço teórico dos Novos Estudos do Letramento (STREET, 1984, 2014; ROJO, 2009). Ao utilizar instrumentos de pesquisa como observação em sala de aula, aplicação de entrevistas e questionários com os alunos e o professor da turma, analisou-se as práticas de letramento dos discentes em sua rotina e a sua relação com o que é ofertado pelo colégio na disciplina de Inglês. Verificou-se que, apesar de os alunos possuírem vivências ricas e diversificadas com a língua no seu dia a dia, há dissonância com relação aos seus letramentos na vida social e o que é priorizado na disciplina de língua inglesa.
entextualizações do discurso político em indivíduos com vieses ideológicos opostos
Authors: CAMILLO PEREIRA CARLOS GUSTAVO
Published: September 2021

Este trabalho se desenvolve a partir da concepção de que a linguagem é performática e de que possui potenciais para o estabelecimento de hegemonias como uma de suas principais características. Assim, os discursos são formas de agir e de atuar na sociedade. Dessa forma, analisamos, às luz dos pressupostos da entextualização e dos indexais, a aderência ou discordância do discurso do atual Presidente da República em dois grupos de facebook com vieses ideológicos opostos em ambiente de web 2.0. Assim, argumentamos que a ideologia é um importante dispositivo que está imbricado nas práticas discursivas e atuantes nas construções dos discursos dos indivíduos. Em adição, o engajamento dos indivíduos em ambientes virtuais demonstram uma nova dinâmica de lidar com o acesso a informação, o que resulta em uma disputa de territoriedade reveladas por meio do ato de aderir ou de se colocar contra os discursos performados pelo Presidente da República em questão. Dessa maneira, os ambientes virtuais tonaram-se locais de luta pela construção de práticas hegemônicas ou de resistências. Em relação à escolha dos procedimentos de redução de números de dados gerados, ela se deu de forma qualitativa, uma vez que não seria possível investigar as entextualizações presentes nas centenas de comentários dada a extensão deste trabalho.
lugar das construções interrogativas de perguntas no ensino de língua portuguesa
Authors: Luiz Pompeu Varela Fernando
Published: September 2021

O presente trabalho parte do princípio de que o estudo acerca das construções interrogativas é fundamental tanto para o desenvolvimento da competência comunicativa quanto para o uso adequado da língua (PEREIRA, 2015), e que, além disso, inserida no processo do perguntar, como prática de linguagem, em contextos de educação, podem contribuir para a ampliação da capacidade de aprendizagem de maneira autônoma e crítica pelo educando. Entretanto, apesar dos documentos normatizadores de educação proporem que sejam desenvolvidas práticas de linguagem, como a elaboração de perguntas, as atividades e os métodos de ensino e de materiais didáticos usados em sala de aula não se encontram propostas de trabalhos para uma consciência linguística mais desenvolvida que oriente de modo efetivo a elaboração de propostas de ensino capazes de fazer com que indivíduos desenvolvam plenamente suas habilidades, não só para uso da língua, mas para a construção do conhecimento a respeito das construções interrogativas. Por essa razão, busca-se compreender o lugar dessas construções linguísticas no âmbito da educação, tendo em vista a disciplina de língua portuguesa.
Acessibilidade textual e endereçamento: contribuições bakhtinianas para estratégias de simplificação textual
Authors: Cortina Silva Asafe Davi , Da Silva Moll Eduardo , Becker Lopes Perna Cristina
Published: September 2021

O objetivo do presente artigo é relacionar os conceitos bakhtinianos de endereçamento e de leitor presumido com práticas de Acessibilidade e Simplificação Textual. Ainda que pesquisas na área de Acessibilidade e Simplificação Textual orientem práticas linguísticas para aplicação de estratégias de simplificação, parece haver uma lacuna na compreensão de “leitor” e de sua importância primária como orientador de [re]escrita simplificada. Por esse motivo, os conceitos de Bakhtin são fundamentais e podem embasar teoricamente o estatuto do leitor e seu papel nas práticas de compreensão discursiva, iluminando, assim, a aplicação de estratégias. Além disso, buscamos destacar a importância de considerar os meios midiáticos nos quais informações serão disponibilizadas, uma vez que, de acordo com Charaudeau, não apenas o enunciado, mas a forma como o enunciado é disposto influenciam na sua compreensão. Primeiro, apresentaremos um breve conceito das áreas de Acessibilidade, Complexidade e Simplificação Textual e do estatuto do leitor para as áreas. Em seguida, abordaremos as ideias de endereçamento e de leitor presumido e a relação desses conceitos com [re]escrita acessível, seguidos por considerações a respeito de acessibilidade para mídias digitais. Após, abordaremos algumas instruções de especialistas em acessibilidade para a internet. Por fim, apresentaremos um exemplo de pesquisa na qual foram aplicadas estratégias de simplificação e um exemplo de site informativo com elementos que tornam a compreensão menos acessível.
Narrativas autobiográficas de migrantes e refugiados
Authors: Amaral Vitral Hollerbach Athayde Igor , Maria Silva Cavalcante Sandra
Published: September 2021

Neste trabalho, investigamos, em uma perspectiva cognitivo-enunciativa, o processo de construção identitária de migrantes e refugiados, por meio de narrativas autobiográficas, enfatizando o modo como, ao narrarem a sua experiência de chegada ao país de acolhida, colocam em cena afetos e constroem diferentes pontos de vista. Descrevemos, no processo de análise do corpus, os modos como o sujeito se encena, construindo, discursivamente, perspectivas de diferentes “eus” – em diferentes tempos e espaços – ao referenciar a própria trajetória de readaptação sociocultural. O corpus da pesquisa foi constituído no campo de uma prática de extensão universitária, mais precisamente, em oficinas de ensino de português como língua de acolhimento, e analisado à luz da teoria de redes de integração conceptual (BRANDT; 2014) e de estudos que atribuem status de relevância às emoções nos processos de produção de sentido (CAVALCANTE; MILITÃO, 2014). A partir de nossas análises, foi possível concluir que a formação identitária do enunciador-migrante resulta de um movimento cognitivo que reconstrói um “eu-ontem-lá”, integrando-o a outros “selves” para a constituição do “eu-aqui-agora”.
Aprendizagem móvel como prática contemporânea
Authors: Silva de Andrade Luiza , Buhr Pedro Brenda Michelle , Rohling Effting Rosangela , Costa Pontes Marco Aurélio , Barros Soares Mariana Luisa , Vales Lacerda Vagno
Published: September 2021

A crescente demanda por soluções inovadoras aliadas às práticas de ensino e aprendizagem gera um aumento no uso de dispositivos móveis não apenas por parte dos alunos, mas também por professores em suas práticas pedagógicas. Este artigo busca traçar uma reflexão a partir da análise de relatos de práticas docentes de pesquisadores cujas experiências foram baseadas nas mais recentes teorias sobre aprendizagem móvel. Para tanto, foi realizado um levantamento bibliográfico de publicações recentes (entre 2013 e 2019) que abordam conceitos-chave dos debates sobre aprendizagem móvel conforme propostos no programa de conteúdo de aulas do Programa de Pós-graduação em Estudos Linguísticos da Universidade Federal de Minas Gerais (POSLIN/UFMG), no segundo semestre de 2020. Traçando um fio condutor que nos leva do operacional ao social, conclui-se que  a aprendizagem móvel precisa ganhar mais atenção nos currículos de formação de professores, visando não somente ao reconhecimento das tecnologias e suas affordances mas, também, reflexões constantes sobre a postura do educador diante das novas tecnologias e das práticas (sociais) digitais por intermédio de dispositivos móveis.

Authors: Rosendo de Souza José Marcos , De Lima Neto Izaías Serafim , Pessoa Sampaio Maria Lúcia
Published: September 2021

A Lei 10.436 de 2002 provocou mudanças em diferentes contextos da comunidade surda brasileira e um desses foi o processo de escolarização, tendo em vista que hoje é recorrente a presença de Surdos em ambientes escolares. Logo, torna-se urgente repensar práticas de formação leitora levando em consideração a Libras, por isso pretendemos com este trabalho discutir sobre letramento literário e Libras, além de expormos o reconto como atividade que pode proporcionar a formação leitora de alunos Surdos. Realizamos uma pesquisa bibliográfica e analítica do reconto da obra literária infantil Chapeuzinho Vermelho. Concluímos que o reconto é uma atividade que permite a apropriação das macro e microestruturas do texto base pelo leitor.
Arquitetura simulada
Authors: Fiori Arantes Otília Beatriz
Published: September 2021

Nos dois ensaios que compõem este e-book – “Arquitetura Simulada” (1988) e “Margens da Arquitetura” (1993) – encontram-se os primeiros registros, na obra de Otília Arantes, da produção arquitetônica que se seguiu ao esgotamento da Arquitetura dos Modernos. Produção que trazia, enfaticamente, a marca característica do novo Espírito do Tempo: a entrada em cena, aparatosa e espetacular – pois afinal se trata de arquitetura e de sua nova centralidade na ordem capitalista emergente –, de uma das dimensões mais ostensivas do paradigma dito da Comunicação. Acompanhamos assim a metamorfose do formalismo, em que culminara a exaustão dos Movimento Moderno (analisada aqui pela primeira vez nos escritos de Otília), num universo de imagens autorreferidas, elevadas ao paroxismo da imaterialidade do Simulacro. Para explicar essa mutação da Arquitetura depois dos Modernos, a Autora recorre, entre outras providências materialistas, às observações de Walter Benjamin acerca da disciplina tátil do olhar na origem desse triunfo duvidoso da pura visualidade, lembrando que é justamente na arquitetura da cidade que se encontra a matriz dessa civilização do Simulacro. Como é demonstrado já no roteiro do primeiro ensaio. Partindo da espetacularidade fachadística da  arquitetura que fazia publicidade de si mesma na 1ª Bienal de Arquitetura de Veneza (1980), com sua Strada Novissima a lembrar as ruas de Las Vegas, passando pelas fantasias high tech de uma arquitetura de Science Fiction, como a do grupo inglês, do Archigram, ou pela Arquitetura contextual (chamada à época, pela Autora, de “contextualismo crítico”, e que, um pouco nas pegadas de Frampton, pretendia, ao menos neste texto, que pudesse assumir o papel de uma arquitetura de resistência), até chegar àquela arquitetura que se autointitulava “frívola”, na acepção mesma que lhe atribuía Eisenman, ou “fútil” (utilizando o conceito de Derrida, referência teórica explícita do arquiteto). Ou seja, até o limite de uma arquitetura reduzida a um jogo infinito de combinações e desconstruções. Análise retomada e expandida no segundo texto –  apresentação do catálogo de uma exposição de Peter Eisenman no MASP, desta vez concentrando-se na obra paradoxal do arquiteto mais emblemático da virada desconstrucionista.  Um arquitetura que se instala na sua “margem”, outra palavra chave da novíssima filosofia francesa à época.

Published: September 2021

Despite the promising performance on benchmark datasets that deep convolutional neural networks have exhibited in single image super-resolution (SISR), there are two underlying limitations to existing methods. First, current supervised learning-based SISR methods for remote sensing satellite imagery do not use paired real sensor data, instead operating on simulated high-resolution (HR) and low-resolution (LR) image-pairs (typically HR images with their bicubic-degraded LR counterparts), which often yield poor performance on real-world LR images. Second, SISR is an ill-posed problem, and the super-resolved image from discriminatively trained networks with

norm loss is an average of the infinite possible HR images, thus, always has low perceptual quality. Though this issue can be mitigated by generative adversarial network (GAN), it is still hard to search in the whole solution-space and find the best solution. In this paper, we focus on real-world application and introduce a new multisensor dataset for real-world remote sensing satellite imagery super-resolution. In addition, we propose a novel conditional GAN scheme for SISR task which can further reduce the solution-space. Therefore, the super-resolved images have not only high fidelity, but high perceptual quality as well. Extensive experiments demonstrate that networks trained on the introduced dataset can obtain better performances than those trained on simulated data. Additionally, the proposed conditional GAN scheme can achieve better perceptual quality while obtaining comparable fidelity over the state-of-the-art methods.
The value of physical culture and health-improving activity in the physical training of students with weakened health

Published: September 2021

The article examines the key features of the organisation of physical culture and health-improving activities in the framework of physical training of students with impaired health. The considered research problem lies in the contradiction between the need to improve physical culture and health-improving activity in higher training and the lack in the modern training system of effective practices for organising physical training of students with impaired health. The study examines the main changes in recent years in the practice of organising physical culture and health-improving activities for students with impaired health, we reveal the mechanism for the formation of special medical groups, as well as their differentiation depending on the type of students' diseases. The importance of increasing the effectiveness of physical culture and health-improving activity in universities is noted, in view of the continuing growth in the number of students with impaired health. Based on the analysis of the current state of the system of physical training of university students, the main problems inherent in this area are highlighted, namely – the diversity of competences in the field of physical culture, the lack of balance between the acquisition of theoretical knowledge and the physical activity of students with impaired health, the lack of a motivational aspect in the system of physical training. The need for a qualitative modernisation of the practice of applying the competency approach to physical training of students and the introduction of a motivational component in the curriculum for physical culture is emphasised. For the further development of this direction, it is necessary to find and maintain a balance between theoretical work and obtaining practical skills in the process of physical culture and health-improving activities, as well as the ability to apply them in subsequent life.
Choosing assessment techniques in teaching English for specific purposes
Authors: Koroleva Natalia Y.
Published: September 2021

The problem of adequate assessment of foreign language proficiency has always been in the focus of investigations dedicated to modern methods and technologies of teaching foreign languages. Recently, more attention has been paid to using alternative assessment methods generated by the teachers of foreign languages themselves and offering the system of multi-directional prolonged criteria based assessment of foreign language competences. It is argued that alternative assessment techniques better correspond to the teaching technologies used by individual teachers, stimulate brain activities, develop creative and logical thinking. This article considers and analyzes one of the models of authentic assessment which is becoming more and more popular – forming an educational portfolio. Examples of this authentic assessment model practical application in teaching business English to the students studying for a Bachelor’s degree in tourism and in teaching English for specific purposes to the students studying for a master’s degree in jewelry are provided and summarised.

Authors: Kortov Sergey V. , Patrakov Eduard V. , Razikova Natalia I. , Terlyga Nadezhda G. , Shulgin Dmitriy B.
Published: September 2021

The article is theoretical in nature and represents a methodological analysis of risks and their role in innovation. The article highlights and analyses different approaches to the study of risks – economic, technological, political, social, institutional, socio-psychological and philosophical-psychological. On the basis of the listed approaches, the authors have proposed a multi-vector model for analysing the risks of innovation, which includes three vectors – economic and technological, socio-environmental and psychological. The advantages and directions for improving the proposed model are also disclosed. It is assumed that the model will be in demand for training the specialists in entrepreneurship and innovation, in assessing the risks of innovation and as a basis for further research in multidimensional risks of innovation and the role of the human factor in such risks.
Self-realisation, self-actualisation and self-efficacy concepts theoretical analysis
Authors: Opekina Tatyana Petrovna , Shipova Natalya Sergeevna
Published: September 2021

This article presents the results of a theoretical study of self-realisation, self-actualisation and self-efficacy phenomena. The main aspects of understanding and correlating these phenomena in classical and modern Russian and foreign psychology are described. The highlighted concepts related to the phenomenon of self-realisation, both in the field of psychology and pedagogy. The similarities and differences of the self-realisation, self-actualisation, self-efficacy phenomena, as well as their correlation and comparison are presented. A comparative analysis of the studied concepts is given. According to the results of the theoretical analysis, the processes of self-realisation and self-actualisation are based on the inner motivation of a person to grow, develop personality, realise its potential. Both of these processes, due to their subjectivity, are difficult to observe and measure from the outside. We have highlighted the main differences, consisting in a greater awareness and orderliness of the process of self-realisation, as well as its predominantly "social" orientation, while self-actualisation is often associated with the struggle with external forces, the desire for self-realisation is rather approved and supported by the society. The concepts of self-realisation and self-efficacy are united by their inherent representation in the external plane of the life of the individual, as well as awareness, activity, goal-setting, and an orientation towards achieving success. In contrast to self-efficacy, self-release is a process rather than a sustainable phenomenon, and can be expressed both externally and internally through a connection with the value-semantic, motivational spheres of the individual.
