Ambiente Virtual de Aprendizagem no ensino de Matemática: relato de experiência
Authors: Sousa Santos Dinelise , Silva Castilho Weimar , Porto Cavalcante Rivadavia , Gomes Silveira de Sena Mary Lúcia , Dias Pereira Filho Albano
Published: January 2021

As novas Tecnologias da Informação e Comunicação possibilitam o uso do Ambiente Virtual de Aprendizagem (AVA), permitindo que haja maior interatividade do aluno com o cotidiano, estabelecendo relações com o ensino da Matemática, estimulando os educadores a repensarem suas práticas pedagógicas em situações de pandemia mundial. O objetivo do presente estudo foi relatar a experiência do emprego do AVA, na perspectiva dos docentes da disciplina, no ensino médio integrado. Um questionário foi respondido por 14 licenciados na área, composto por oito questões fechadas e três questões abertas sobre o uso dos ambientes virtuais. Eles consideraram os AVA’s (Moodle ou Google Classroom) ferramentas de apoio facilitadoras do aprendizado, do processo de construção de conhecimentos e interação entre os alunos e os professores. O compartilhamento das ideias possibilitou uma aprendizagem significativa e colaborativa, mesmo perante as dificuldades postas pela nova situação. O estudo revelou um recurso didático alternativo em situações que houver medidas de restrição de contato social.
Modelagem Matemática e Educação do Campo: conteúdos emergentes na abordagem de uma situação da vivência dos estudantes
Authors: Schrenk Maykon Jhonatan , Vertuan Rodolfo Eduardo
Published: January 2021

Neste trabalho, relatamos uma experiência de sala de aula em uma escola do campo e investigamos quais conteúdos emergem de uma atividade de Modelagem Matemática que envolve os estudantes com situações de sua vivência, mais especificamente, no cuidado da horta escolar. A prática foi realizada com 10 estudantes do 2º ao 5º ano do Ensino Fundamental de uma escola municipal do campo localizada em uma cidade do oeste do Paraná que participavam de um projeto no período contraturno, em que eram desenvolvidas atividades de matemática. Foram utilizadas como instrumentos de coleta de dados as anotações do pesquisador em um diário de campo e os registros das atividades realizadas pelos estudantes em seus cadernos. Já para a organização e a análise dos dados, tomamos como suporte teórico a Análise de Conteúdo, com a construção de categorias a posteriori. A partir da experiência, podemos inferir, dentre outras coisas, que os estudantes perceberam que os conteúdos que eles aprendem e as situações-problemas que eles presenciam em sala de aula podem ter importância para sua vivência fora da escola, principalmente no campo, e vice-versa, compreendendo que é necessário aprender matemática, as outras disciplinas e refletir sobre suas experiências extraescolares nos diferentes contextos, sendo a escola, também neste aspecto, um espaço privilegiado para potencializar seus conhecimentos.
A inclusão de estudantes com deficiência visual no Ensino Superior em cursos de exatas: um relato de caso
Authors: Paixão Borges Pedro , C. de Segadas-Vianna Claudia
Published: January 2021

Nos últimos anos, podemos observar um aumento do número de matrículas de pessoas com deficiência visual no Ensino Superior. Particularmente no caso de cursos de exatas, onde estes alunos estão historicamente pouco presentes, esses novos perfis estudantis acabam por evidenciar a pouca preparação estrutural e metodológica das universidades para o estabelecimento de práticas inclusivas. Dessa maneira, torna-se necessário compreender de forma mais clara como se dá o processo de inclusão desses alunos nos espaços universitários, apontando os entraves encontrados e divulgando estratégias bem-sucedidas de ensino-aprendizagem. No presente trabalho, realizamos uma entrevista com um estudante cego matriculado no segundo período do curso de Engenharia em uma universidade pública do Estado do Rio de Janeiro. Através do relato de sua trajetória escolar e universitária, analisamos os obstáculos e sucessos encontrados por este aluno, apresentando algumas especificidades do ensino de Matemática para alunos com deficiência visual e apontando possíveis caminhos para uma universidade mais inclusiva.

Processo de conceituação da medida e outras questões imbricadas: uma leitura histórico-cultural
Authors: Araújo Neuton ALVES , Moura Teixeira Cristiane de Sousa
Published: January 2021

Nesse estudo, apresentamos reflexões teóricas, resumidamente, de uma investigação em nível de doutorado que teve como objetivo central investigar o processo de apropriação de conceitos matemáticos por professores que ensinam Matemática no Ensino Fundamental, inseridos num projeto de formação continuada que apresenta estrutura funcional da 'atividade' com base nos pressupostos teórico-filosóficos da Teoria Histórico-Cultural. Especificamente sobre estas reflexões, buscamos, portanto, resposta à questão que norteou o estudo em evidência: Como podemos explicar o processo de reconstituição lógica considerando a origem e o desenvolvimento histórico do conceito de medida? Na busca por essa resposta, a priori, em linhas gerais, discutimos sobre o processo conceitual, destacando, por exemplo, que, ao longo da história é visível a ocorrência de saltos qualitativos na forma como o homem ousou pensar, o que outrora foi denominado por pensamento mítico. Feito isso, nos detemos na explicação do processo histórico-social de produção do conceito de medida, analisando as suas três fases de desenvolvimento, a saber: medidas antropométricas, prática utilitária e o conhecimento matemático enquanto processo de abstrações: as relações. Por estar imbricada nesta problemática, ou seja, no processo de desenvolvimento conceitual, também discutimos sobre a natureza social do pensamento, tendo a linguagem como seu instrumento constitutivo. Seguindo essa mesma lógica, por último, com o intuito de tornarmos a discussão da dinâmica relativa ao processo conceitual mais compreensível, explicamos e caracterizamos os dois níveis de modalidades de pensamento: o empírico e o teórico-científico. Nessa direção, no encadeamento das reflexões empreendidas, ficou evidenciado que o conceito de medida, assim como os conceitos no geral, se constitui como tais a partir da relação homem-mundo, ou ainda, que não se desenvolvem naturalmente, mas resultam das condições históricas e sociais em que as experiências humanas suscitam novas necessidades. Portanto, não têm origem primária no pensamento humano, mas nas práticas sociais.
A ABORDAGEM DE FRAÇÃO EM LIVROS DIDÁTICOS DE MATEMÁTICA DO SEXTO ANO DO ENSINO FUNDAMENTAL APROVADOS NO PNLD DE 2020
Authors: Souza Carvalho Euvaldo de , Vizolli Idemar , Rodrigues Pereira Onésimo
Published: January 2021

Dada a problemática existente em torno do ensino e da aprendizagem de fração, nos desafiamos a analisar o modo como livros didáticos, aprovados no Programa Nacional do Livro Didático (PNLD) do ano de 2020, apresentam o conteúdo de fração aos estudantes do 6° Ano do Ensino Fundamental. A consecução da pesquisa bibliográfica se deu a partir de uma consulta à literatura que tematiza o processo de ensino e aprendizagem do conceito de fração, considerando os diferentes significados e as características das quantidades. Foram analisadas as nove obras disponíveis em meio digital, embora o PNLD conte com onze coleções para consulta pelos professores. É possível inferir que as obras analisadas apresentam o conteúdo de fração sem considerar os conceitos abordados neste trabalho, aspectos primordiais ao processo de compreensão conceitual. Outrossim, priorizam quantidades contínuas e extensivas e o significado parte – todo em detrimento das demais abordagens.

Evidence-informed interventions and best practices for supporting women experiencing or at risk of homelessness: a scoping review with gender and equity analysis
Authors: Andermann Anne , Mott Sebastian , Mathew Christine M. , Kendall Claire , Mendonca Oreen , Harriott Dawnmarie , McLellan Andrew , Riddle Alison , Saad Ammar , Iqbal Warda , Magwood Olivia , Pottie Kevin
Published: January 2021

Introduction

While much of the literature on homelessness is centred on the experience of men, women make up over one-quarter of Canada’s homeless population. Research has shown that women experiencing homelessness are often hidden (i.e. provisionally housed) and have different pathways into homelessness and different needs as compared to men. The objective of this research is to identify evidence-based interventions and best practices to better support women experiencing or at risk of homelessness.

Methods

We conducted a scoping review with a gender and equity analysis. This involved searching MEDLINE, CINAHL, PsycINFO and other databases for systematic reviews and randomized trials, supplementing our search through reference scanning and grey literature, followed by a qualitative synthesis of the evidence that examined gender and equity considerations.

Results

Of the 4102 articles identified on homelessness interventions, only 4 systematic reviews and 9 randomized trials were exclusively conducted on women or published disaggregated data enabling a gender analysis. Interventions with the strongest evidence included post-shelter advocacy counselling for women experiencing homelessness due to intimate partner violence, as well as case management and permanent housing subsidies (e.g. tenant-based rental assistance vouchers), which were shown to reduce homelessness, food insecurity, exposure to violence and psychosocial distress, as well as promote school stability and child well-being.

Conclusion

Much of the evidence on interventions to better support women experiencing homelessness focusses on those accessing domestic violence or family shelters. Since many more women are experiencing or at risk of hidden homelessness, population-based strategies are also needed to reduce gender inequity and exposure to violence, which are among the main structural drivers of homelessness among women.

This research focuses on the using of WhatsApp in teaching pronunciation practice to the third semester students of Tadris English Study Program in IAIN Palu. The research question is “How is the using of WhatsApp in teaching Pronunciation Practice to the third semester students of Tadris English Study Program in IAIN Palu?” This is a qualitative research by using two instruments of data collections namely questionnaire and interview. The participants consisted of 19 third semester students of Tadris English Study Program of State Institute for Islamic Studies (IAIN) Palu. The researcher conducted five meetings of Pronunciation Practice class to the participants via WhatsApp before distributing the questionnaire and interview sheet. The questionnaire consisted of five questions by applying Likert Scale, while the interview consisted of ten questions. From the questionnaire and interview, the researcher concludes that the using of WhatsApp in teaching Pronunciation Practice to the third semester students of Tadris English Study Program in IAIN Palu is practical. The students could understand the material shared via WhatsApp in the form of documents shared, videos shared, as well as voice recording shared. They could use the features in WhatsApp well such as sharing documents, voice notes, sharing videos, video call and so on in learning pronunciation practice. The students like Pronunciation Practice Class and enjoy studying it via WhatsApp. Learning Pronunciation Practice via WhatsApp has some advantages such as time flexibility as well as structured and easily accessed materials. However, it also has some limitations such as internet data availability and video call limitation. Besides, the participants faced several obstacles in learning Pronunication Practice via WhatsApp, such as the limitation of smartphone memory to save files, down internet server, and unavailability of internet data. Nevertheless, they could passed those obstacles well by deleting some unused files to give more space to the memory and finding out wifi connection to stay connected to WhatsApp when the server was down or they ran out of internet data. They could understand the teaching of Pronunciation Practice via WhatsApp by downloading and reading the documents shared, the videos shared, and the voice recording shared by the lecturer. When they found a difficulty, they asked their friends or the lecturer via WhatsApp group.

The Alien Fraction of the Woody Flora of Yelanetskyi Step Nature Reserve, Southern Ukraine
Authors: Konaikova Valeriia O. , Vakarenko Olena V.
Published: January 2021

Results of investigations on the patterns of distribution and dispersal of alien species of trees and shrubs in the territory of a steppe protected area, Yelanetskyi Step Nature Reserve (Mykolaiv Region, southern Ukraine), are presented. We registered within this protected area 10 alien woody species. For the most widespread ones (Ulmus pumila L., Gleditsia triacanthos L., Elaeagnus angustifolia L., Robinia pseudoacacia L.), we carried out ecological analyses. In order to establish the scope of impact of ecological factors upon these species, their specificity, and interdependence between ecological factors, the phytoindication method was applied (Didukh, 2012). The results of our analysis conducted on 12 main ecological factors (as outlined by Didukh, 2011), such as soil water regime (Hd), variability of damping (Fh), soil aeration (Ae), soil acidity (Rc), nitrogen content (Nt), salt regime (Sl), carbonate content in soil (Ca), thermoregime (Tm), climate humidity (Om), continentality (Kn), cryoregime (Cr), and light intensity (Lc), show that dispersal of model alien species does not have ecological limitation. However, E.angustifolia and R.pseudoacacia have the strongest capacity to penetrate the steppe communities, especially disturbed ones. Further dispersal of these alien species in the studied area and adjacent territories is hampered only by the integrity of the structure of steppe communities.
Prevalence and influencing factors of low back pain among nurses in China: a systematic review and meta-analysis
Authors: Wang Dong-Yang , Sun Yu-Yan
Published: January 2021

Background

Low back pain (LBP) is one of the most common occupational injuries that nurses experience in their daily work, which ultimately causes disability or difficulty in performing heavy physical activity. There is scarce information that presents a direct figure about the prevalence of LBP in Chinese nurses.

Objective

To systematically review and analyze the prevalence and influencing factors of LBP among nurses in China.

Methods

Related literature extracted from PubMed, Web of Science, Scopus, China National Knowledge Infrastructure databases were selected and reviewed based on the PRISMA guideline. Random effects models were used for data analysis, where heterogeneity was tested through I2. Egger's test was used to analyze the literature publication bias.

Results

The combined data indicated that the prevalence of LBP among nurses in China was 78% [95% confidence interval (CI) = 0.72–0.83]. The prevalence of LBP among nurses in China has declined in the past decade. Nurses presented a high risk of LBP in terms of female (OR = 2.38, 95% CI = 1.23–3.44, P < 0.0001), married (OR = 2.79, 95% CI = 1.57–3.86, P < 0.0001), 24 ≤ BMI < 28 (OR = 2.03, 95% CI = 1.18–3.08, P < 0.0001), and working for more than ten >10 years (OR = 2.54, 95% CI = 2.03–3.32, P < 0.0001).

Conclusions

There is a high prevalence of LBP among nurses in China. Interventions that include healthy dietary habits and physical activity mainly focusing on female married nurses who are working for at least 10 years should be implemented. Furthermore, nurses ought to apply ergonomic principles for personal protection at the workplace.

Authors: Wu Jun , Yang Zhi-Lan
Published: January 2021

Objective

To understand the psychological process of patients with post-herpetic neuralgia (PHN) and provide references for the psychological management of PHN.

Methods

The objective sampling method was used to conduct semi-structural in-depth interviews on 10 PHN patients, and Colaizzi's phenomenological analysis method was used for data analysis.

Results

According to the different pain durations of PHN patients, the patients were divided into three stages and five themes were extracted: the need for strong pain relief, the helpless tolerance of pain, the self-feeling burden, the need for health education, and the positive response to pain.

Conclusions

PHN has complex psychological activities, so it is necessary to pay attention to the psychological process of patients and take effective psychological measures to intervene negative psychology so that patients can actively cope with the pain.
Toxicity of gaseous ozone to the different life stages of cowpea beetle, Callosobruchus maculatus (Coleoptera: Bruchidae), under laboratory conditions
Authors: Gad H.A. , Sileem T.M. , Hassan R.S. , Abdelgaleil S.A.M.
Published: January 2021

The cowpea beetle, Callosobruchus maculatus (Fabricius), is recognized as a common insect pest of cowpea worldwide. The present study aimed to evaluate the insecticidal activity of ozone gas against all life stages (egg, larva, pupa and adult) of C. maculatus at a concentration of 600 ppm (1.2 g/ m3) after 6 exposure times of 0.5, 1, 2, 3, 4 and 5 h under laboratory conditions. The mortality percentages of all life stages were significantly increased with increasing exposure time. Similarly, longer exposure time to ozone caused higher reduction of adult emergence from eggs, larvae and pupae. Treatment with ozone for 5 h caused egg mortality of 72.3%. Total mortality of adults was observed 5 days after treatment with ozone for 0.5 h. Moreover, treatment with ozone for 5 h resulted in 75, 100 and 94.1% reductions in adult emergence from eggs, larvae and pupae, respectively. The results also indicated that the larvae and adults were more susceptible to ozone gas than the eggs and pupae. Based on the findings, ozone showed promising insecticidal activity against all stages of C. maculatus and could be used as potential fumigant for management of this insect.
Rainfall and self-selection patterns in Mexico-US migration
Authors: Li Shan
Published: January 2021

This article studies the role of rainfall in determining the education composition of Mexico-US migration. Emphasizing the relationship between rainfall and migration costs, a revised Roy model indicates that rainfall affects selection on education through not only households’ liquidity constraints but also the comparisons between changes in migration costs and wage differentials at different levels of education. With retrospective data on the migration history of male Mexicans, the empirical analysis shows that the inverted U-shaped relationship between migration probabilities and education is less dispersed with a higher vertex when rainfall decreases, suggesting higher migration costs and reinforced self-selection patterns. The impacts of rainfall on selection and education are stronger for the migrant stock than for migration flows. Studying how rainfall influences migrants’ return decisions provides consistent results.

Published: January 2021

It is a common challenge for the surgeon to detect pathological tissues and determine the resection margin during a minimally invasive surgery. In this study, we present a drop-in sensor probe based on the electrical bioimpedance spectroscopic technology, which can be grasped by a laparoscopic forceps and controlled by the surgeon to inspect suspicious tissue area conveniently. The probe is designed with an optimized electrode and a suitable shape specifically for Minimally Invasive Surgery (MIS). Subsequently, a series of ex vivo experiments are carried out with porcine liver tissue for feasibility validation. During the experiments, impedance measured at frequencies from 1 kHz to 2 MHz are collected on both normal tissues and water soaked tissue. In addition, classifiers based on discriminant analysis are developed. The result of the experiment indicate that the sensor probe can be used to measure the impedance of the tissue easily and the developed tissue classifier achieved accuracy of 80% and 100% respectively.

Conceptualizing the strategies of representing the image of Russia: History and Evolution (communicative aspects)
Authors: Kolokoltseva E. V.
Published: January 2021

The paper addresses the issue of the genesis and the evolution of the conceptual formation of the official attitudes toward the principles governing the representation of the Russian Federation and their scientific covering. It appearance in key foreign policy documents and its significance is analyzed with the view to two major conceptual schemes: the international image and the objective perception. Both concepts were examined with comparative research methods. The problems of tracing the current transformations in the official rhetoric to the transformations that are now taking shape in promoting Russia are the factors why this issue is relevant. The particular aspects of the research included the key documents of official bodies endowed with powers to shape foreign policy that were published in the period between 2000 and 2019. The activities of the key institutions and content providers in what concerns international positioning were outlines. Holding and covering mega-events, such as the 2014 Sochi Winter Olympics and the 2018 FIFA World Cup, also served the image needs and, in this respect, was examined in the paper. The concept and method of soft power is introduced for analysis, as it is increasingly efficient and useful in both these respects. The paper concludes with stating that the practice of positive positioning of Russia abroad was substituted in favour of the one of engendering objective perception. The main concern for that consisted in foreign pressure and negative information campaigns, so the decision was a counter measure. In this context, the shift between the two concepts of international promotion is revealed in official documents, having a considerable effect on the communicative potential in terms of acting in accordance with the fundamental values and real attitudes inherent in the Russian culture. Esse quam videri is now not only the national principle, but also the foreign image.

The main attention is paid to the problems arisen from overcoming traumas by the means of art and to the influence the traumatic experience has had on the transformation of the artistic language. The themes of the horrors of war, war and post-war experience and reflections acquire special significance in the artistic culture of the 20th century, with traumas brought by both world wars and other conflicts giving rise not only to emotional responses to ongoing disasters, but also being a catalyst for global reshaping of artistic content, form and industry, expressed in the visual revolution. In this regard, the paper turns to the essential cultural characteristics of the art of this period, to consider the similarities and differences in the individual trends that followed the general trend. Then, revealing the specifics of the artistic process, considered within the framework of the historical and cultural approach, the reasons that determined the global transformations of art were discovered. In this work, the issues mentioned above are perceived at the junction of the problems studied in the history of emotions and the history of art. So is the conceptual focus of this interdisciplinary text. Such an approach not only attempts to consider the visual revolution through the prism of personal experience, to link the transformation of visual expression with the inner state of a person and one’s perceptions of current events. It also underlines the specificities of historiography, represented both by research on the history of art and by works related to such a direction of historical science as the history of emotions. The main results of the research are as follows. Works of art related to the experience and display of the horrors of war, on the one hand, help to understand and survive the traumatic experience, telling about it in a metaphorical form, and on the other hand, embodying these goals, they radically change the artistic language in the context of the visual revolution of the 20th century.
Which Way Will Catalonia Go?
Authors: Anikeeva N. E.
Published: January 2021

Catalonia’s historical fate, the peculiarities of regional history drawn against the background of relations with the Spanish capital and, thus, the Catalan separatism are the issues examined in Ramón Tamames’ book that has appeared in its seventh edition in 2018. Showing both diachronic and comparative perspectives, the work of Prof. Tamames provides fruitful insights into modern traces of centurieslasting complex, complicated, if not to say tense attitudes of the Spanish government to Barcelona and local visions of the central authority. The new edition of the book embraces the nuances of this phenomenon in the period from the rise of the unified Spanish monarchy in 1479 up to the 2017 controversial independence referendum. According to the findings of Prof. Tamames, Catalonia’s independence project lacks legitimacy in many ways and, consequently, is absurd. This issue is growing in importance now, in the wake of the coronavirus crisis shaking the precarious balance of Spain’s center-region relations.

Interpretation of the Concept of Religious Syncretism in Western European and Russian Researches
Authors: Sidakova M. O.
Published: January 2021

The article is devoted to religious syncretism, in particular, the history of its research in Western European and Russian science. Most foreign researchers give an ambiguous assessment of the mother concept of syncretism. However, when for Russian researchers syncretism is a universal term used to describe a group of processes and seems not to be problematic, in the Western European scientific community anthropologists and religious scholars have been actively discussing its application for almost fifty years: works devoted to religious syncretism, as a rule, are necessarily accompanied by a number of reservations, and in other cases researchers deliberately avoid it altogether, preferring to use synonymous concepts with a less complicated history. In this way the main objective this paper sets is to compare the visions of the Russian and the foreign academy on the term, map and draw the margins of the conceptual use that both Russian and European scholars share, shedding light on contexts and reasons. Positioning the concept within the field of its use, the text also notes the wide context of the referent phenomenon. Processes of spreading the boundaries of identity and religious self-determination are now taking place against the background of globalization. In this regard, the topic of religious syncretism not only has not lost its relevance, but, on the contrary, is increasingly at the center of religious studies. The author of the article covers the history of the emergence of the concept in religious studies. On the basis of comparative analysis, the traces of the coverage of this phenomenon in scientific publications of Western European and Russian researchers are shown. It is also revealed, how the connotations of the concept of religious syncretism have changed, with the key discrepancies and gaps in scientific approaches identified, and the main types of contexts in which it appears differentiated.
Техническое переоснащение предприятий
угольной промышленности Приморья в годы индустриализации
Authors:   А.В. Маклюков, О.К. Павленко
Published: January 2021

В статье рассматриваются исторические аспекты процесса технического
переоснащения угольной отрасли Приморья в 1930-е гг., выявляются предпосылки, условия и трудности перехода угольных предприятий региона на
новую техническую основу. На смену полукустарным дореволюционным
шахтам, основанным на ручном труде и паровых машинах, пришли современные технически оснащенные механизированные угледобывающие предприятия, работающие на машинах с электрическим приводом, однако процесс технического переоснащения шахт Приморья под влиянием различных
факторов происходил медленнее, чем в других районах страны. Несмотря
на это, как заключают авторы, приморские шахты в годы индустриализации
стали главной топливной базой для развития электроэнергетики, индустрии
и оборонной промышленности Дальнего Востока.

The article examines the history of the technical re-equipment of the coal industry
in Primorye in the 1930s, identifying the background, conditions and difficulties
of coal enterprises’ transition to new technical base. The pre-revolutionary
semi-artisan mines based on manual labor and steam engines were replaced by
modern technically equipped mechanized coal mining enterprises, however, the
process of technical re-equipment here went slower than in other regions of the
Soviet Union due to the influence of various factors. Nevertheless, as the authors
conclude, during industrialization the coal mines of Primorye became the main
fuel base for the development of power generation, industry and defense sector
in the Soviet Far East.
