Published: December 2020

Background: The deposition of amyloid-β (Aβ) and hyperphosphorylation of tau are well-known as the pathophysiological features of Alzheimer’s disease (AD), leading to oxidative stress and synaptic deficits followed by cognitive symptoms. We already demonstrated that betaine (glycine betaine) prevented cognitive impairment and hippocampal oxidative stress in mice intracerebroventricularly injected with an active fragment of Aβ, whereas the effect of betaine in chronic models of AD remains unknown. Objective: Our objective was to investigate the effects of chronic betaine intake on cognitive impairment and aberrant expression of genes involved in synapse and antioxidant activity in the hippocampus of a genetic AD model. Methods: We performed cognitive tests and RT-PCR in the hippocampus in 3xTg mice, a genetic AD model. Results: Cognitive impairment in the Y-maze and novel object recognition tests became evident in 3xTg mice at 9 months old, and not earlier, indicating that cognitive impairment in 3xTg mice developed age-dependently. To examine the preventive effect of betaine on such cognitive impairment, 3xTg mice were fed betaine-containing water for 3 months from 6 to 9 months old, and subsequently subjected to behavioral tests, in which betaine intake prevented the development of cognitive impairment in 3xTg mice. Additionally, the expression levels of genes involved in synapse and antioxidant activity were downregulated in hippocampus of 3xTg mice at 9 months old compared with age-matched wild-type mice, which were suppressed by betaine intake. Conclusion: Betaine may be applicable as an agent preventing the progression of AD by improving the synaptic structure/function and/or antioxidant activity.

Authors: Sataraddi Mamata J. , Kakkasageri Mahabaleshwar S.
Published: December 2020

VANET is mainly aimed at providing safety and security related information and traffic management. In future, VANET contributes to smart transportation system. Based on vehicle mobility, different routing protocols and traffic models were developed. In routing, trust between vehicles place an important role to forward safety related information. This paper aims at design of trust and delay based routing for hybrid communication in sparse VANET to avoid network attacks by malicious nodes. The proposed hybrid routing protocol works on the computation of trust in between vehicles and message reachable time (MRT). Route selection is done by considering the highest trust factor and minimum MRT. The performance effectiveness of the proposed scheme is evaluated by comparing with the Delay-aware and Backbone-based Geographic Routing for Urban VANETs (DBGR). The proposed scheme exhibits better performance in terms of packet delivery ratio, bandwidth utilization, end-to-end delay and control overheads.

Authors: Diao Lijing , Hu Ping
Published: December 2020

On the basis of convolution neural network, deep learning algorithm can make the convolution layer convolute the input image to complete the hierarchical expression of feature information, which makes pattern recognition more simple and accurate. Now, in the theory of multimodal discourse analysis, the nonverbal features in communication are studied as a symbol system similar to language. In this paper, the author analyzes the deep learning complexity and multimodal target recognition application in English education system. Multimodal teaching gradually has its practical significance in the process of rich teaching resources. The large-scale application of multimedia technology in college English classroom is conducive to the construction of a real language environment. The simulation results show that the multi-layer and one-dimensional convolution structure of the product neural network can effectively complete many natural language problems, including the tagging of lexical and semantic roles, and thus effectively improve the accuracy of natural language processing. Multimodal teaching mode helps to memorize vocabulary images more deeply. 84% of students think that multi-modal teaching mode is closer to life. Meanwhile, multimedia teaching display is more acceptable. College English teachers should renew their teaching concepts and adapt themselves to the new teaching mode.
Mining of top-k high utility itemsets with negative utility
Authors: Sun Rui , Han Meng , Zhang Chunyan , Shen Mingyao , Du Shiyu
Published: December 2020

High utility itemset mining (HUIM) with negative utility is an emerging data mining task. However, the setting of the minimum utility threshold is always a challenge when mining high utility itemsets (HUIs) with negative items. Although the top-k HUIM method is very common, this method can only mine itemsets with positive items, and the problem of missing itemsets occurs when mining itemsets with negative items. To solve this problem, we first propose an effective algorithm called THN (Top-k High Utility Itemset Mining with Negative Utility). It proposes a strategy for automatically increasing the minimum utility threshold. In order to solve the problem of multiple scans of the database, it uses transaction merging and dataset projection technology. It uses a redefined sub-tree utility value and a redefined local utility value to prune the search space. Experimental results on real datasets show that THN is efficient in terms of runtime and memory usage, and has excellent scalability. Moreover, experiments show that THN performs particularly well on dense datasets.

Still little is known about the nature of the gastrointestinal pathological alterations occurring in Parkinson’s disease (PD). Here, we used multiplexed mRNA profiling to measure the expression of a panel of 770 genes related to neuropathological processes in deep submucosal rectal biopsies of PD patients and healthy controls. Altered enteric neuropathological traits based on the expression of 22 genes related to neuroglial and mitochondrial functions, vesicle trafficking and inflammation was observed in 9 out of 12 PD patients in comparison to healthy controls. These results provide new evidences that intestinal neuropathological alterations may occur in a large proportion of PD patients.

Published: December 2020

BACKGROUND: Neonatal hyperbilirubinemia is a common medical emergency in early neonatal period. Unconjugated bilirubin is neurotoxic and can lead to lifelong neurological sequelae in survivors. OBJECTIVE: To find out the association between serum bilirubin and neurodevelopmental outcome at 1 year of age using Development Assessment Scale for Indian Infants (DASII). METHODS: A prospective cohort study was conducted in the Department of Pediatrics of a tertiary care institution of Central India between January 2018 and August 2019. Total 108 term healthy neonates, with at least one serum bilirubin value of >15 mg/dl, were included. Subjects were divided into three groups based on the serum bilirubin; group 1: (15–20 mg/dl) –85(78.7%) cases, group 2: (20–25 mg/dl) –17(15.7%), and group 3: (>25 mg/dl) –6(5.5%). Developmental assessment was done using DASII at 3, 6, 9, 12 months of age. RESULTS: Out of 108 cases, 101(93.5%) received phototherapy, and 7(6.5%) received double volume exchange transfusion. Severe delay was observed in 5(4.6%) and mild delay in 2(1.9%) cases in the motor domain of DASII at one year. Severe delay in the motor domain was associated with mean TSB of 27.940±2.89 mg/dl and mild delay with mean TSB of 22.75±1.76 mg/dl (p = 0.001). On cluster analysis, delay was observed in locomotion 1 score in 11(13%) cases (p = 0.003) and manipulation score in 6(7.1%) cases in group 1. CONCLUSION: Increased serum bilirubin was a significant risk factor for the delayed neurodevelopment in babies with neonatal jaundice. Even a moderate level of bilirubin significantly affects the developmental outcome.

Multivariable Modified Teaching Learning Based Optimization (MM-TLBO) Algorithm for Inverse Modeling of Residual Gravity Anomaly Generated by Simple Geometric Shapes
Authors: Eshaghzadeh Ata , Hajian Alireza
Published: December 2020

This paper presents an improved nature-based algorithm, namely multivariable modified teaching learning based optimization (MM-TLBO) algorithm, as in an iterative process can estimates the best values for the model parameters in a multi-objective problem. The algorithm works in two computational phases: the teacher phase and the learner phase. The major purpose of the MM-TLBO algorithm is to improve the value of the learners and thus, improving the value of the model parameters which leads to the optimal solution. The variables of each learner (model) are the radius ( R), depth ( h), shape factor ( q), density contrast ( ρ) and axis location ( x0) parameters. We apply MM-TLBO and TLBO methods for the residual gravity anomalies caused by the buried masses with a simple geometry such as spheres, horizontal and vertical cylinders. The efficiency of these methods are also tested by noise corruption synthetic data, as the acceptable results were obtained. The obtained results indicate the better performance the MM-TLBO algorithm than the TLBO algorithm. We have utilized the MM-TLBO for the interpretation of the six residual gravity anomaly profiles from Iran, USA, Sweden and Senegal. The advantage of the MM-TLBO inversion is that it can estimates the best solutions very fast without falling into local minimum and reaches to a premature convergence. The considered primary population for the synthetic and real gravity data are thirty and fifty models. The results show which this method is able to achieve the optimal responses even if a small population of learners had been considered.

Published: December 2020

An induction coil sensor (ICS) is important for measuring low-frequency (DC-1kHz) geomagnetic field. The accuracy of the preamplifier is one key factor determining the performance of the sensor. But the preamplifier is susceptible to 1/ f noise, offset voltage and drift. In order to eliminate these influences, a preamplifier circuit with three amplifier stages based on chopper technology has been designed, and its performance has been tested. The results show that: 1) The 1/ f noise corner frequency is 3 mHz, the equivalent input voltage noise (EIVN) level of the circuit is [Formula: see text] and [Formula: see text]; 2) The equivalent input current noise (EICN) level of the circuit is [Formula: see text]; 3) The offset voltage is about 600 nV, and the time drift performance is excellent. In conclusion, the preamplifier circuit has characteristics of ultralow noise, low offset voltage and low time drift. It can effectively amplify low-frequency weak geomagnetic signals from 1 mHz to 1 kHz and provides excellent performance for low-frequency ICS.
DAGESTAN REGION BETWEEN THE TWO REVOLUTIONS OF 1917
(BALANCE OF SOCIO-POLITICAL POWERS)
Authors: Salihova Leyla B. , Ayagan Burkutbay G.
Published: December 2020

The article discusses the distribution of socio-political powers in Dagestan region during the period of the February and October revolutions of 1917. The aim of the paper is to examine the process of formation of socio-political groups, to consider their opposition. The February events of 1917 in Petrograd led to the victory of the revolution. In this regard, a difficult situation arose in the Dagestan region: the victory led to a deterioration of the political situation, to demarcation within the opposing political forces. The paper highlights the formation of various political groups and government bodies which replaced tsarism. The study shows that the Provisional Regional Executive Committee and its district and local authorities, Councils of Soldiers and Officers (Workers) Deputies, religious communities, organizations belonging to one or another ethnic group, etc. were organized in the region. The authors point out the organization of the Provisional Regional Executive Committee, which became the body of power of the Provisional Government, to the opposition of the members of the committee itself, to the organization of Union of Allied Mountaineers of the North Caucasus and Dagestan, etc. The fact that representatives of socio-political groups took an active part in congresses and meetings held in the North Caucasus, Dagestan is noted.
Analysis of the period under study demonstrates that the political situation in Dagestan was tense, however the struggle of opposing parties was carried out within the democratic principles. It mainly manifested itself in the struggle between the socialist group and representatives of N. Gotsinsky. When writing the paper, the works of domestic researchers was used, among which the works of contemporaries of revolutionary events.
Global Flows, Local Conditions and Productivity Spillovers: The Case of the Central and Eastern European Countries
Authors: Éltető Andrea , Alguacil Maite
Published: December 2020

The evolution of labour productivity in an economy can be affected by technology transfer through international linkages, as this permits the incorporation of innovation and automation intensive capital goods into the local productive system. Globalization may be an opportunity to promote sustainable growth – within the industry 4.0 framework – in economies with low levels of innovation or automation. In this paper, we analyse the role of global flows and local conditions for a sustainable productivity growth in the EU member states of Central and Eastern Europe. We focus on the imports of capital goods and foreign direct investment (FDI) inflows as main drivers of technology diffusion and productivity spillovers. As productivity also depends on the local capacity for technology adoption, in this work, we control for domestic factors, such as the domestic investment, R&D expenditure, levels of human capital and the quality of local institutions. Our estimates based on panel data models for 2000-2018, confirm that capital imports have been productivity enhancing in Central and Eastern European countries. Evidence that FDI inflows have a positive influence in the transmission of technology is vague or insignificant according to our model. Finally, our estimates show that countries with higher R&D spending, stronger institutions and higher physical and human capital endowments enjoy higher productivity gains

Published: December 2020

Memory modules are widely used in varies kind of electronics system design. The capacity of the memory modules has increased rapidly since the past few years in order to satisfy the high demand from the end-users. The memory modules’ manufacturers demand more units of automatic test equipment (ATE)to increase the production rate. However, the existing ATE used in the industry to carry out the memory testing is too costly(at least a million dollars per ATE tester). The low-cost memory testers are urgently needed to increase the production rate of the memory module. This has in spired us to design a low-cost memory tester. A low-cost memory fault detection tester with all the major fault detection algorithms that used in industry is modelled using Very High Speed Integrated Circuit Hardware Description Language (VHDL) in this paper to support the need of the low-cost ATE memory tester. The fault detection algorithms modelled are MATS+ (Modified Algorithm Test Sequence), MATS++, March C, March C-, March X ,March Y, zero-one and checkerboard scan tests. PERL program is used to analyse the simulation results and a log file will be generated at the end of the memory test. Extensive simulation and experimental test results show that the memory tester modelled covers all the memory test algorithms used in the industry. The low-cost memory fault detection tester designed provides the 100% fault detection coverage for all memory defects.
The Coin of Love and Virtue: Academic Libraries and Value in a Global Pandemic
Authors: Seale Maura , Mirza Rafia
Published: December 2020

In September 2010, the Association of College and Research Libraries released The Value of Academic Libraries: A Comprehensive Research Review and Report. The spread of the novel coronavirus and the resulting global pandemic has raised questions about the concept of value in academic libraries. How is value attributed? How does value function? What does it mean to demonstrate or prove our value? We begin with an overview and analysis of ACRL’s Value of Academic Libraries Initiative. We then provide a description and timeline of the spread of COVID-19 and the reaction of both institutions of higher education, academic libraries, professional library organizations, and individual librarians. The pandemic has created a new category of workers - “essential workers” - who provide vital services, perform maintenance work, and labor to keep infrastructures intact. The role of carework and careworkers in the pandemic helps illuminate the situation of academic librarians within regimes of neoliberal austerity. Ultimately we argue that although the discourse of library value seeks to prove library value rationally and empirically, through a lot of quantitative data, capitalism, the economy, and value are fundamentally irrational. Academic library value must be claimed politically; misrecognizing the nature of the problem and relying on commonsense understandings of value and the economic, which is what the discourse of library value has done for the past decade, goes nowhere.

Avulsion of a permanent tooth is a serious condition and a true dental emergency that can be associated with other traumatic injuries. In addition, in reimplanted avulsed teeth, ankylosis and external replacement resorption (ERR) are two typical biological responses, with long-term progression and outcome associated with the patient's growth stage. The purpose of this report is to present the long-term outcome of an 18-year-old patient who was the victim of a motor vehicle traffic accident that resulted in traumatic injury to the maxillary incisors, including an avulsed central incisor with extensive external replacement resorption (tooth 11). Twenty-two years later, due to the continuous effect of the ERR process on the reimplanted tooth and favorable bone weight, it was decided to perform rehabilitation with immediate guided implant by a simplified method (KEA-TECH system). In young patients, the decision to maintain the tooth even under unfavorable conditions may delay rehabilitation with implants.

Published: December 2020

Este artigo tem como objetivo elaborar uma revisão bibliográfica sistemática para identificar características do greenwashing e compreender seus efeitos na lealdade do consumidor. Não houve recorte de datas para confecção do estado da arte, pois o assunto é recente e poucos estudos que analisam os efeitos da prática estão disponíveis. Também não houve filtros para o tipo de documento, deixando em aberto artigos em periódico e anais de congressos, teses e dissertações, e-books, relatórios de pesquisa, entre outros. As bases de dados utilizadas para a busca foram a Web of Science, Scopus e Science Direct. Após a busca, os artigos localizados foram incluídos no software Start para realização da RBS. Após as seleções, obteve-se um volume de 94 publicações vinculadas ao assunto, dentre essas, 21 foram selecionadas para leitura completa e, na sequência, oito publicações foram utilizadas para composição final da RBS. Foram identificadas como características do greenwashing: inverdades, informações falsas, comportamento simbólico, informações vagas, dentre outras. O efeito da prática de greenwashing na lealdade é a perda da confiança do cliente no produto ou serviço, além do aumento ceticismo. Portanto, a prática do greenwashing é danosa ao meio ambiente e aos negócios da organização.

Física quântica e misticismo no ensino de ciências
Authors: Rocha Tennile Rany , Carvalho Thiago Milograno de , Felicio Cinthia Maria
Published: December 2020

A Física Quântica surgiu em 1900 na tentativa de explicar uma série de fenômenos que a Física Clássica não era capaz. Sua consolidação se deu na década de 1920 enquanto área de conhecimento na tentativa de explicar o funcionamento das coisas ao nível das dimensões dos átomos e partículas subatômicas. Com intuito de fazer um contraponto entre os pontos de vista científico e filosófico-religioso, da mecânica, coloca-se em evidência as interpretações de viés acadêmico e espiritual de modo a explicitar aos leigos, através de uma linguagem acessível, os fatos científicos e as versões desses fatos. Como objetivo específico, adotou-se a análise e aplicabilidade da mecânica quântica nos mais diversos contextos ao longo da história, assim como a deturpação das ideias e da utilização dos termos científicos. Percebe-se que com os resultados desta pesquisa que a tentativa de se fazer uma ligação entre a mecânica e a espiritualidade não tem validade científica. Com o estudo das revisões bibliográficas, conclui-se que o conhecimento científico é fundamental para o desenvolvimento do senso crítico, e consequentemente para o crescimento humano em diversos aspectos e perspectivas de conhecer e interpretar o mundo não apenas em seus aspectos físicos, mas também em filosofia, sociologia e demais campos que propõe uma maior reflexão. Através dos conceitos estruturantes desta área, poderemos entender melhor alguns aspectos do que trata a Física Quântica, sendo uma proposta interessante para percebermos evolução histórica dos conceitos e concepções que podem ser encontradas nas mais diversas épocas, desde a antiguidade até os tempos modernos.

BACKGROUND: Rhabdomyolysis is a potentially fatal disease caused by trauma, infections, and toxins. Rhabdomyolysis has not been reported in Chinese civil aircrew, but in our case report a male civil copilot contracted rhabdomyolysis after excessive exercise, showing potential
for morbidity in pilots.CASE REPORT: After excessive exercise, a 29-yr-old male civil aviation copilot complained of serious myalgia and weakness in lower limb muscles and gross hematuria, whose values of alanine transaminase (ALT), aspartate transaminase (AST), myohemoglobin (Mb),
creatine kinase (CK), CK-MB, lactate dehydrogenase (LDH), and -hydroxybutyrate dehydrogenase (-HBDH) were conspicuously increased. Magnetic resonance imaging showed abnormal signal intensities in the lower limbs. The patient was diagnosed with rhabdomyolysis. He was treated with hydration
and urine alkalinization. When his condition was stabilized, the patient was discharged. After remaining asymptomatic for 3 mo and getting documentation of normalized lab results, he was granted a first-class medical certificate and returned to work.DISCUSSION: This was the first
case of rhabdomyolysis reported in Chinese civil aircrew. Excessive exercise in an overweight pilot may induce rhabdomyolysis. This condition can be controlled and cured by early and effective treatment. Rhabdomyolysis could occur in a population suffering from overweight, obesity, or hyperlipidemia.
This case fits in with several other cases of military pilots exercising excessively. The progression could lead to acute kidney injury without prompt and effective intervention. And common symptoms like muscular weakness or myalgia may induce sudden in-flight incapacitation, so early medical
intervention should be adopted. Moreover, recurrence of rhabdomyolysis should be considered when resuming flying duties.Liu X, Meng X, Zhang C, Chen J, Li P, Wu X, Fan H. Rhabdomyolysis in a civil aviation pilot. Aerosp Med Hum Res. 2020; 91(11):901903.

INTRODUCTION: We assessed determinants of serum hs-CRP level in pilots and air traffic controllers (ATCs) and its impact on their atherosclerotic cardiovascular disease (ASCVD) risk.METHODS: We obtained serum hs-CRP measurements, evaluated traditional cardiovascular
risk factors and assessed global ASCVD risk based on 2018 ESH/ESC guidelines. Elevated hs-CRP was hs-CRP values > 3 mg L1. Determinants of elevated hs-CRP were assessed using stepwise logistic regression analysis. We used the net reclassification method to evaluate the impact
of hs-CRP levels on global ASCVD risk.RESULTS: Of the 335 subjects (mean age 45.4 11.6 yr, 70% pilots, 99% men, 37% Caucasians), 127 individuals (39.5%) presented with elevated hs-CRP levels. Compared to those with normal hs-CRP, individuals with elevated hs-CRP were older with
faster heart rate and higher blood pressure, BMI, and P wave amplitude. The proportion of individuals with elevated hs-CRP was greater among those with smoking habits, physical inactivity, MetS, tachycardia, altered P wave axis, LVH, and HT-TOD. Aging (aOR 2.15 [1.676.98]), hypertension (aOR
3.88 [2.296.58]), type 2 diabetes (aOR 6.71 [1.7710.49]), tachycardia (aOR 2.03 [1.914.53]), and LVH (aOR 2.13 [1.647.11]) were the main factors associated with elevated hs-CRP levels. Low, moderate, high, and very high risk were observed in 24 (15%), 68 (41%), 62 (37%), and 12 (7%) subjects,
respectively. Including hs-CRP resulted in the net reclassification of 25% of subjects, mostly from moderate to high risk.CONCLUSION: The integration of hs-CRP improved the estimation of global ASCVD risk stratification. However, a survey with a comprehensive population assessing
the cost/benefit impact of such a referral is needed.Buila NB, Ntambwe ML, Mupepe DM, Lubenga YN, Bantu J-MB, Mvunzi TS, Kabanda GK, Lepira FB, Kayembe PK, Ditu SM, MBuyamba-Kabangu J-R. The impact of hs-CRP on cardiovascular risk stratification in pilots and air traffic controllers.

Selective Serotonin Reuptake Inhibitor Use Among Army Aviators
Authors: Kelley Amanda M. , Bernhardt Kyle , McPherson Mark , Persson James L. , Gaydos Steven J.
Published: December 2020

INTRODUCTION: Mental health is an important aspect of Army aviation medicine given that it significantly impacts career longevity, readiness, and healthcare usage. One of the most commonly used classes of medications to treat mental health disorders is the selective serotonin
reuptake inhibitor (SSRI). Here we present a descriptive epidemiological review of SSRI use in Army aviators over a 10-yr period.METHODS: An archival dataset retrieved from the U.S. Army Aeromedical Electronic Resource Office covering the years 2005 to 2015 was queried for cases
of SSRI use. Frequencies were generated by primary diagnoses and aeromedical disposition for the SSRI subset of data.RESULTS: A total of 114 unique cases of SSRI use were identified (122 total aeromedical outcomes). These cases included 41 waiver recommendations, 59 suspension recommendations,
and 22 cases of waiver continuations. The top five most common primary diagnoses were depressive disorder (N 32), anxiety state (N 21), posttraumatic stress disorder (N 16), single major depressive episode (N 13), and adjustment disorder with depressed mood (N
12).DISCUSSION: Understanding of the etiology, pathophysiology, and treatment of mental health disorders particularly within the safety-focused and unforgiving aviation environment has continued to evolve. With the application of evidence-based policy, deliberate aeromedical decision-making,
and methodical risk mitigation, SSRI use does have a place within aviation. Aviators suffering in silence with deleterious impact to performance and safety or aircrew seeking services on the outside without knowledge or oversight of certification authorities must remain in the past.Kelley

O INFINITO: COMPREENSÕES QUE PERPASSAM TEORIAS, ENSINO E APRENDIZAGEM
Authors: Araujo Juscimar da Silva , Alves Giovana , Pinheiro José Milton Lopes , Flores César Oswaldo Vásquez
Published: December 2020

Este estudo visa explicitar o que se evidencia como invariante entre teorias que pensam e definem o infinito, e como este invariante se expõe em situações de ensino e de aprendizagem. Para tanto, realiza-se um estudo bibliográfico, retomando o infinito no âmbito de diferentes perspectivas, buscando convergências com as quais se possa expor o que é comum aos discursos nelas articulados.Compreende-se que, em meio às variações formais e epistemológicas, a intuição de infinitude se mostra como um ponto de interseção entre os discursos matemático, físico e filosófico. Evidencia-se que, se inserida a perspectiva do ensino e aprendizagem, o mesmo ponto se destaca, como propostadidática para constituição de um solo perceptivo e intuitivo com o qual se avança a articulação de conceitos mais abstratos de infinito e de conteúdos matemáticos aos quais o mesmo está inserido.
A DISCIPLINA DE MATEMÁTICA NO ENSINO INDUSTRIAL (1942-1964)
Authors: Maciel Paulo Roberto Castor
Published: December 2020

O objetivo do trabalho é caracterizar a disciplina de Matemática no Ensino Industrial no período compreendido entre 1942 e 1964. Utilizou-se a pesquisa histórica para realização balizada pela história cultural (CHARTIER, 2002), cujas fontes de pesquisa foram: legislação do ensino industrial, anais do III Congresso Brasileiro de Ensino de Matemática e seis trabalhos acadêmicos. A legislação definia que a disciplina deveria estar presente em todas as séries do primeiro ciclo e em uma série do segundo ciclo, além de existir uma dualidade relacionada com sua natureza (cultura geral e técnica). Os anais do congresso indicavam a metodologia para ensino da disciplina e um programa voltado para os cursos industriais básicos. Os trabalhos acadêmicos relacionavam a disciplina de forma aplicada, apresentando as diferenças com a disciplina no ensino secundário. Conclui-se que a Matemática deveria estar relacionada com a oficina, mas, apesar disso, manteve características da Matemática do ensino secundário.
CONSIDERAÇÕES TEÓRICO-METODOLÓGICAS SOBRE O DESENVOLVIMENTO DE PROJETOS COLABORATIVOS ENTRE PROFESSORES E PESQUISADORES NA CONSTRUÇÃO DE RECURSOS PARA A SALA DE AULA
Authors: Abar Celina Aparecida Almeida Pereira , Igliori Sonia Barbosa Camargo
Published: December 2020

Neste artigo trazemos reflexões sobre o trabalho colaborativo entre professores e pesquisadores, com o objetivo de construir recursos para a sala de aula. Um trabalho colaborativo dessa forma é assumido por nós como um trabalho realizado “com” e não “sobre” o professor, e tem uma perspectiva de pesquisa-ação-formação. Os resultados devem trazer contribuições tanto para a evolução da pesquisa quanto da prática docente. A colaboração entre professor e pesquisador, portanto, é necessária e frutífera, mas para isso é preciso valorização dos dois tipos de conhecimentos e instrumentos de análise que os possam captar com inteireza. Isso porque, as pesquisas têm revelado que, qualquer que sejam teoria e metodologia norteadoras, o contexto da sala de aula tem que emergir para interessar ao professor e favorecer seu engajamento. A participação em pesquisa colaborativa das autoras deste artigo com professores, revelou que duas situações geram modalidades diferentes de dados que interferem na observação e análise dos resultados: intra (em seu desenvolvimento) e extra (após o desenvolvimento). E assim sendo é nossa proposta a utilização de uma estratégia de conexão de aportes teórico-metodológicos como uma forma de aperfeiçoamento no controle de variáveis, levantamento dos dados e consequente resultados mais significativos. Para tal considera-se a conexão entre dois aportes específicos: a Teoria da Atividade e a Difusão da Inovação para essas duas situações complementares.

Published: December 2020

Este artigo apresenta uma pesquisa cujo objetivo foi averiguar possíveis contribuições do Bingo das Grandezas e Medidas para a construção e mobilização de conhecimentos ligados à habilidade de estimar por estudantes da Educação de Jovens e Adultos. O estudo empírico consistiu na observação participante da aplicação do jogo em uma escola municipal do Recife - PE durante três dias consecutivos, totalizando quatro rodadas, complementada pela realização de entrevista e questionário. Todos os encontros foram filmados e gravados. Os resultados mostram que, no caso dassituações cujo contexto era familiar a pelo menos parte da turma, os participantes estabeleceram relações entre suas experiências e as situações de estimativa propostas no jogo, debateram dificuldades a serem consideradas e partilharam com o grupo seus conhecimentos. No caso de situações menos habituais, eles desenvolveram estratégias, como: utilizar instrumentos de medidas, comparar com outras grandezas e realizar anotações em seus cadernos para registrar valores estimados. De modo geral, o jogo propiciou a mobilização, a partilha e a ampliação do repertório de conhecimentos dos estudantes da EJA em relação à estimativa.
