Utilização de miniparafusos na buccal shelf para mesialização de molares inferiores - Parte 1
Authors: Villela Henrique Mascarenhas
Published: January 2021

INTRODUÇÃO: A mesialização de molares inferiores de corpo é muito frequente na clínica ortodôntica, devido às agenesias e às perdas precoces de molares ou pré-molares. No entanto, esse movimento ortodôntico é difícil de ser efetuado, devido à necessidade de se controlar a rotação, a angulação e o torque desses dentes durante a sua translação. Essa dificuldade decorre, também, do tipo de osso encontrado na mandíbula, que apresenta uma cortical com alta densidade e, muitas vezes, com pouca quantidade de osso medular. A introdução da ancoragem esquelética com miniparafusos trouxe muitos benefícios a essa difícil tarefa, simplificando a mecânica ortodôntica, minimizando os efeitos colaterais indesejados, reduzindo a necessidade de colaboração do paciente e tornando os tratamentos mais previsíveis. Contudo, para realizar essa movimentação de forma mais eficiente, fazem-se necessários a compreensão e o domínio da biomecânica aplicada a esses dispositivos. Com a introdução dos miniparafusos extra-alveolares, novas estratégias surgiram para tirar o máximo de proveito desse dispositivo, que fica localizado na buccal shelf mandibular. Essa localização permite a livre movimentação sagital dos dentes, devido ao fato de o corpo do parafuso ser posicionado em região mais cortical e afastada das raízes dos dentes. OBJETIVO: O presente artigo mostra uma estratégia de tratamento capaz de efetuar a mesialização dos molares inferiores diante da perda de um segundo pré-molar, utilizando a ancoragem esquelética com miniparafuso extra-alveolar na região da buccal shelf. CONCLUSÃO: Por meio dessa estratégia, os molares inferiores são mesializados de corpo, de forma eficiente, sem efeitos colaterais indesejados, com a preservação das estruturas periodontais e obtendo uma boa relação dentária final.
Правовое регулирование опроса общественного мнения на выходе из избирательного участка после голосования (экзитпола)
Authors: Корякина Зинаида Ивановна , Жегусов Юрий Иннокентьевич
Published: January 2021

В статье рассматривается правовой аспект экзитпола — опроса общественного мнения на выходе из избирательного участка после голосования. Несмотря на доказанную эффективность экзитполов, доверие электората и органов власти к данным, предоставляемым ими, а также их востребованность во время и после выборов, в российском федеральном законодательстве отсутствует посвященная этому виду опроса общественного мнения нормативная регламентация. Такой существенный пробел в правовом регулировании может привести не только к нарушениям законодательства, но и конфликтам между избирательными комиссиями и организаторами опросов, а также возникновению небезопасных для субъектов общественных отношений ситуаций, приводящих к правовой неопределенности. Цель статьи — определить правовое регулирование экзитпола путем исследования его соотношения с нормами права для предложения нормативных рекомендаций. На основании определения значения экзитпола в проведении выборов и выявления нормативного (правового) состояния регулирования опроса на выходе из избирательного участка в российском законодательстве в статье исследуются объект и предмет общественных отношений, возникающих при проведении экзитпола и нуждающихся в правовом регулировании. В качестве результата авторы предлагают разработанные ими правовые нормы, регламентирующие порядок проведения экзитпола.

Agresywne zachowania uczniów ze SPE jako źródła lęków nauczycieli. Korelacja osłabiająca sukces edukacji włączającej
Authors: Baranowska Wanda , Leszka Justyna
Published: January 2021

In inclusive education, teachers work with all students, including those exhibiting aggressive behaviors. Today, many teachers struggle with challenging student behavior. The study aims to examine (1) aggressive behaviors in students with SPE – a source of teacher frustration in inclusive education, (2) the consequences of these behaviors triggering fears in teachers, and (3) the relationship between teacher seniority and likely consequences as per objective 2. The survey was conducted among 188 teachers. The data were analyzed using descriptive and correlational approaches. We determined that (1) the main source of teacher frustration is the physical aggression displayed by students with ASD, ADHD, ODD and CD; (2) the fear students with SEN may hurt other students is prominent amongst teachers, with a linear correlation between predictable consequences, where the strongest links appear between prediction of conflict in a classroom and the accusation of incompetence levelled at teachers by parents of students with SEN and between the fear of losing self-control and disapproval by superiors; (3) no significant relationship exists between the seniority of teachers and their perception of the sources of frustrations and fears. Against the background of the results, we formulated recommendations on inclusive education training for teachers.

Authors: Sovetova Kundyz , Ismailova Akmaral
Published: January 2021

In the production of chromium and in the process of transportation of chromiumcontaining materials, contamination of natural waters and soils with chromium compounds inevitably occurs. In this paper, the sorption of chromium (VI) ions with carbon sorbents is studied as a method for treating waste and natural water contaminated with chromiumcontaining compounds. Sorption method of extraction and concentration of elements is one of the most effective and simple technological method of chromium extraction. For extraction of chromium (VI), carbon sorbents obtained from recycling of wheat grains waste (RWGW) (wheat husk or bran) modified with ammonium nitrate were used. RWGW (recycling of wheat grains waste) + NH4NO3 (3%), RWGW (recycling of wheat grains waste) + NH4NO3 (5%), RWGW (recycling of wheat grains waste) + NH4NO3 (7%) were used. Chromium sorption was investigated depending on various factors. It has been established that the most effective sorbent is RWGW (recycling of wheat grains waste) + NH4NO3 (3%), with which it is possible to extract chromium by 98% from solutions at pH=1 in 30 min. This sorbent has been tested for industrial wastewater treatment containing up to 36 mg/L of chromium (VI) ions. The metal recovery rate was 95.2%. The obtained results indicate the prospects of application of RWGW (recycling of wheat grains waste) + NH4NO3 (3%) for wastewater treatment from chromium (VI).

Published: January 2021

Annona muricata L. is widely known throughout Indonesia as having great potentials as an antidiabetic agent. This study aimed to evaluate the antihyperglycemic effectiveness of ethanol extract 96% from soursop leaves and to compare its effects to metformin and insulin aspart injection as antidiabetic agents. This was a cross-sectional experimental study with random sampling approach which was performed at Phytochemistry and Biopharmacy Laboratory, Faculty of Pharmacy, Hasannudin University, Indonesia, from February 17 to March 3, 2020. Twenty-four Mus musculus subjects induced by streptozotocin were divided into six groups, which received 96% ethanol extract from Annona muricata in various doses. The extract was produced using the maceration process. The fasting blood sugar level was measured using the point of care testing (POCT) method, and data collected were then analyzed using a univariate approach. Results showed that the average fasting blood glucose level (FBG) was decreasing with increasing doses (5 g/kgBW=127 mg/dL, 10 g/kgBW =114 mg/dL, and 15 g/kg BW=97.75 mg/dl with a p-value of 0.000 based on repeated ANOVA. When compared to the positive control 1 (metformin), the decrease in FBG level in this control group (70.67 mg/dL) was better than in the group that received ethanol extract from Annona muricata L. In subjects in positive control 2 (insulin aspart), the average FBG level remained high, which was 473 mg/dL. Hence, 96% ethanol extract of Annona muricata L. can effectively lower fasting blood glucose in Mus musculus.

Authors: Velcheva Albena
Published: January 2021

The article describes the development of didactics and auto-didactics using the diachronic approach. The relation between didactics, as a major and traditional part of pedagogical science, and autodidactics, as its variety and alternative, is presented in the context of the law of unity and struggle of opposites, which is the "core" of dialectics. The validity of the general laws of dialectics and their relation to pedagogical science is argued. From a philosophical and pedagogical point of view, the basic principles are formulated, arising from the interdependence and contradiction in the didactics autodidactics system as factors for the sustainable development of education.

Published: January 2021

Nowadays, almost every woman is at high risk because of stress during pregnancy, but their nature, intensity, duration of exposure are different for each woman. Extremely high-risk groups are pregnant women living in conditions of military aggression, social and humanitarian crises. The period of reactive adaptation to stress in them is rapidly changing maladaptation. This is due to neuro-immunological mechanisms, which are further implemented in the complicated pregnancy and childbirth. The objective: is to establish the stressors effects on the function of the immune system of pregnant women and their possible role in the occurrence of complications of gestation. Materials and methods. To achieve this goal, we surveyed 78 pregnant women in the third trimester of pregnancy. They were divided into 2 groups: 1 group (main) – 42 pregnant women, displaced from Lugansk and Donetsk regions, 2 group – 36 pregnant women with physiological pregnancy. General clinical studies, psychological testing (Spielberger–Hanin scale) and immunological studies: population and subpopulation composition of blood lymphocytes using the method of indirect immunofluorescence using monoclonal antibodies CD3+, CD4+, CD4+, CD8+, CD8+ CD20 + and CD16 +, study of lymphocyte functional activity and determination of CIC were conducted. Results. Total lymphopenia and significant increase in the level of circulating immune complexes (CIC) were found in pregnant women of the 1 group (forcibly displaced). This indicates a state of marked suppression of immunity (lymphopenia), complicated pregnancy, susceptibility to infectious-inflammatory processes, severe course and prolonged convalescence. The number of lymphocytes was within the normative parameters in pregnant women of the second group. Activation of the number of T cells (CD4+, CD8+, CD16+), as well as their functional activity (RBTL) were found. Which points at the activation of the T-cells immunity type. Conclusions. The results of the study prove the immunosuppressive role of psychosocial factors in internally displaced women and the presence of stress-induced decompensation of the psychoneuroendocrine system in them. Keywords: psychoneuroimmunology, pregnancy, anxiety, women–forcibly displaced, stress.

Published: January 2021

The obstetrician-gynaecologist practitioners consider a woman’s health from her reproductive potential support standpoint, and the problem of miscarriage is considered as one of the most important health problems in the world. The difficulty in solving the premature birth problem is the presence of many factors and preconditions that determine the risks of miscarriage. The article provides an overview of current international guidelines for assessing the root causes and preconditions for preterm birth. The problem of preterm birth risks is discussed, taking into account both the socio-economic living conditions of pregnant women and the factors that accompany the formation of the pathogenesis of preterm birth (placental dysfunction). Attention is paid to the hemodynamic disorders assessment (vascularization of the lower uterus) in pregnant women and determination of their role in the fetoplacental dysfunction development. The role of the hemodynamic disorders in the placenta is considered as the morphological and biochemical adaptive reactions abnormality. Keywords: miscarriage, premature birth, fetoplacental complex, placental dysfunction.

Authors: Robandi Iman Imaduddin , Soetikno Ristaniah D. , Dewi Dian Komala
Published: January 2021

Background: Coronary heart disease (CHD) is a disease that raises public health concerns due to its high morbidity and mortality rates. Anatomically, epicardial fat is located around the heart and coronary system, making it important in the development of coronary atherosclerosis. This study aimed to explore the relationship between epicardial fat volume (EFV) and the type of coronary artery plaque by using Cardiac Computed Tomoghraphy (CT)-Scan. Methods: This was a cross-sectional observational analytic study on patients diagnosed with CHD aged > 20 years who had undergone cardiac CT-Scan at the Department of Radiology, Dr. Hasan Sadikin General Hospital, Bandung, Indonesia between February and June 2019. Data collected from the CT-Scan were analyzed using the Chi-square test. Results: From 54 CHD patients, consisting of an equal number of male and female patients, with a majority of above 60 years old (31.5%), a correlation was identified between increased amount of EFV and mix and hard plaques in the right cirumflex artery (RCA) (p<0.026) and left circumflex (LCX) (p<0.038)On the left main(LM) and left anterior descending (LAD) arteries, no significant correlation was observed between EFV and the type of plaque (p>0.05). Conclusions: There is a significant relationship between the EFV value, EFV category, and the type of coronary artery plaque in CHD patients in RCA and LCX arteries. However, this correlation is not observed in LM and LAD arteries.

Published: January 2021

Sulfolane is an organosulfur solvent, which has been widely used to remove acid components from sour natural gas. In recent years, it has been detected in soil and groundwater near gas-processing plants in North America, becoming a potential threat to ecosystems and human health. Previous bench-scale studies have shown that aerobic degradation is a promising method for treating sulfolane in contaminated soil. In this study, field-scale aerobic biopile technologies were evaluated to treat sulfolane-contaminated soil in western Alberta, Canada. Six field-scale (25–300 m3) soil biopiles with different nutrient and aeration conditions were constructed on the sulfolane-contaminated site. The sulfolane concentration, carbon dioxide (CO2)/oxygen (O2) level and moisture content in the soil piles were monitored throughout the remediation period. The results indicated that sulfolane can be degraded slowly in the soil biopiles without nutrient addition and aeration. The soil biopiles with nutrient addition and aeration yielded the best performance in degrading sulfolane with a rate of 42 (mg/kg)/day. It is concluded that soil biopiles is an effective technology to remediate sulfolane-contaminated soil under field conditions.
Public-Private Partnership in the World Economy: Possible Negative Consequences
Authors: Merzlov Igor
Published: January 2021

The widespread claims that PPPs are more effective, that they redistribute the risks between the public and private parties and, as a result, provide the best «Value for Money» (VfM) are not always supported by appropriate evidence. This study is a theoretical review, which aims to demonstrate the potential risks associated with the use of PPP, and help us better understand this concept. Among the negative effects identified are the following: 1) restriction on competition and the development of small and medium-sized businesses,; 2) the predominance of economic projects objectives over socially important ones; 3) rising unemployment; 4) relatively greater increase in direct budget spending; 5) side effects related to creation of institutional environment; 6) relatively large costs of developing and carrying out tender procedures; 7) high costs of legal support; 8) corruption; 9) «hidden» increase of state budget debt. As a result, those negative consequences of PPPs are inextricably linked with the quality of their structuring at the stages of initiation and tender documentation preparation.
Against Game Studies
Authors: Gekker Alex
Published: January 2021

The article explores the limitations of the current scholarly game studies (GS) field. Its central presuppositions are (1) that there are certain attributes broadly understood as “GS” by those writing in or adjacent to the field; (2) that those attributes are historically rooted in an attempt to disassociate videogames from other types of electronic (and later—digital) media; and that (3) the preconditions that have led to this split are currently moot. In the first section of this article, I elaborate on these presuppositions through reading GS as a historically rooted field, centred around the videogame artefact. Following, by examining the notion of being ‘against’ something in academic work, I move to my central claim for the article: that maintaining this conception of GS is counterproductive to the state of contemporary videogames scholarship and that adopting a post-dualistic and post-humanities stance will greatly contribute to the broadening of the field. I break down this claim into three separate threads. Ontologically, I show that videogames are much closer to non-videogames than they used to be. Methodologically, I point out how re-integrating methodologies from outside the field is crucial to address the complex phenomena evolved in and around gaming. Politically, I highlight the importance of games in contemporary digital culture and show how boundary-work and gatekeeping might harm the attempt to make game scholarship engage with larger political issues. The article concludes with suggestions for a more inclusive and intermingled vision for the field, focusing on the notion of play rather than games.

Published: January 2021

This thematic issue presents a number of emerging scholarships into the study of digital gaming. The articles are based on a 2019 symposium on game studies hosted by the Digital Games Research section of ECREA. As the phenomena related to digital gaming keep on evolving and emerging, so must research keep up with the times and constantly challenge itself. Whether speaking about validating previously developed research methods, imagining totally new ones, or even challenging the whole philosophy of science on which research is being done, there is a constant need for reappraisal and introspection within games research. As a cultural medium that has become deeply embedded into the social fabric of the 2020s, digital gaming continues to excite and challenge academia. This thematic issue provides a collection of approaches to look into the future that addresses some of the challenges associated with game research.

Kapital Politik: Kuasa yang Mengikat dalam Relasi Kerja Nelayan dan Pangamba’ di Pondok Mimbo
Authors: Rivaldi Adhe Yoga
Published: January 2021

This article discusses the role of power on the work relations of fishermen and the middle man at Pondok Mimbo. Engagement occurs when the fisherman builds a partnership and accept a work contract, as long as the contract has not been completed. The fisherman must provide the fish catch to the middle man before it is sold to the trader and then share the results according to the work agreement which is 10% to 20% for the middle man from the income of the fisherman. The absence of work contract restrictions makes the relationship so binding because fishermen must comply with the amba system 'or the prevailing norms. As a result, fishermen will continue to be bound to the middle man but, because the relationship is for capital needs, it requires fishermen to pay it to the middle man to be free from the employment contract. The purpose of this study is to describe and analyze the role of political capital in the relations of fishermen and the middle man. This research method is qualitative, supported by participant observation, and in-depth interviews to collect data. The results showed the existence of power in the work relations of fishermen and the middle man especially in the attitude of compliance, even showing the existence of work competition in the relationship. And each party is cheating work for more profit, whether it's from the fishermen themselves or the middle man. Artikel ini membahas tentang tindakan kuasa atau penggunaan kekuasaan dalam relasi kerja nelayan dan pangamba’ di Pondok Mimbo. Keterikatan terjadi ketika nelayan membangun kerja sama dan menyepakati kontrak kerja dengan pangamba’, tselama kontrak belum selesai maka nelayan harus memberikan hasil tangkapan ikan kepada pangamba’ sebelum di jual ke pedagang yang kemudian dilakukan pembagian hasil sesuai kesepakatan kerja yaitu 10% hingga 20% untuk pangamba’ dari hasil pendapatan nelayan. Tidak adanya batasan kontrak kerja menjadikan relasi tersebut begitu mengikat, karena nelayan harus mematuhi sistim amba’ atau norma yang berlaku. Alhasil, nelayan akan terus terikat dengan pangamba’ namun, karena relasi tersebut untuk kebutuhan modal, mengharuskan nelayan untuk melunasinya kepada pangamba’ agar dapat lepas dari kontrak kerja tersebut. Tujuan penelitian ini untuk mendeskripsikan dan menganalisis peran kapital politik dalam relasi nelayan dan pangamba’. Metode penelitian ini adalah kualitatif, didukung dengan melakukan observasi partisipan dan wawancara mendalam untuk mengumpulkan data. Hasil penelitian menunjukan adanya kekuasaan dalam relasi kerja nelayan dan pangamba’, terutama pada sikap kepatuhan, bahkan menunjukan adanya persaingan kerja dalam relasi tersebut. Selanjurnya, penelitian juga menunjukkan bahwa masing-masing pihak melakukan kecurangan kerja demi keuntungan yang lebih, entah itu dari diri nelayan maupun pangamba’.

Published: January 2021

The current study presents the development of a student outcome standard framework for competence-based teacher training programs in universities of education. The outcome standard framework was built in direction of approaching students’ quality, competency including 5 standards: Key qualities; Core competences; Pedagogical competence; Specialistic scientific competence; Self-study, research and profession development competence. Based on this standard framework, education universities can build student outcome standards for each training program following a multiple-step controlled process. Each student outcome standard of a training program must transparently determine specific requirements of profession competencies. Each standard consists of the criteria of the target-competence and then, each criterion is specifically specified into indicators with several typical-specific behaviors. From this standard framework, education universities can develop student outcome assessment instruments (checklist\ scale\ or questionnaire) for evaluating graduated-student outcome quality\ effectiveness of every teacher training program.

Boosting up Source Scanner Identification Using Wavelets and Convolutional Neural Networks
Authors: Rabah Chaima Ben , Coatrieux Gouenou , Abdelfattah Riadh
Published: January 2021

In this paper, we present a conceptually innovative method for source scanner identification (SSI), that is to say, identifying the scanner at the origin of a scanned document. Solutions from literature can distinguish between scanners of different brands and models but fail to differentiate between scanners of the same models. To overcome this issue, the approach we propose takes advantage of a convolutional neural network (CNN) to automatically extract intrinsic scanner features from the distribution of the coefficients of the diagonal high-frequency (HH) sub-band of the discrete stationary wavelet transform (SWT) of scanned images. Such information serves as a reliable characteristic to classify scanners of different/same brands and models. Experiments conducted on a set of 8 scanners yielded a model with an accuracy of 99.31% at the block level and 100% at the full image level, showcasing the potential of using deep learning for SSI and outperforming existing schemes from literature. The influence of the model’s parameters such as the input size, the training data size, the number of layers, and the number of nodes in the fully connected layer as well as the effect of the pre-processing step were investigated.

BACKGROUND Patients with critical illness can have changes in thyroid hormone metabolism along with changes within the hypothalamus-pituitary-thyroid axis, even though there is no previous history of thyroid disease. Such changes have been named as “Sick Euthyroid Syndrome” or “Non-Thyroidal Illness Syndrome (NTIS)”. Such alterations in thyroid function can be seen in patients with sepsis and they are known to affect the prognosis of the disease. The most common abnormality in sick euthyroid syndrome is low serum T3. This study aims to find the proportion and pattern of sick euthyroid syndrome in patients with sepsis. METHODS This was a hospital based cross sectional study done in the Department of Internal Medicine in a tertiary care centre in south Kerala. 100 patients with diagnosis of sepsis were selected based on American College of Chest Physician / Society of Critical Care Medicine 2001 Consensus Conference definitions, and included in the study. Serum levels of total T3, total T4 and TSH were measured and the proportion of patients with various abnormalities in thyroid hormone levels and the pattern of abnormalities were analysed. RESULTS The mean age of study group was 67.9 years (with standard deviation of 7.184). Female to male ratio was 1.08:1. Proportion of sick euthyroid syndrome in patients with sepsis was 71 %. Low T3 was seen in 69 % patients, low T4 in 11 % and low TSH in 11 %. TSH was above reference range in 3 % patients. The most common pattern of sick euthyroid syndrome was low T3 with normal T4 and TSH in 54 % patients. Low T3 with low T4 and normal TSH was seen in 6 % patients; low T3, T4, TSH in 5 % patients; low T3, elevated TSH, normal T4 in 3 % patients; low TSH with normal T3 and T4 in 2 % patients and low T3, low TSH and normal T4 in 1 % patients. CONCLUSIONS Proportion of sick euthyroid syndrome in sepsis was 71 % and the most common pattern was low T3 with normal T4 and TSH seen in 54 % patients. KEYWORDS Sick Euthyroid Syndrome, T3, T4, TSH

The method laser Doppler-flowmetria (LDF) carries out research of indicators of a microcirculatory bed at 66 patients with fractures of long tubular bones the early postoperative period. It was established, that at patients as with an uncomplicated current, and development of the slowed down consolidation of fractures in the first days of a trauma the microcirculation indicator, the maximum amplitude of fluctuations of components of a vascular tonus decreases, the neurogenic, myogenetic tonus raises, the given parametres remain invariable for the second days of the postoperative period. At the slowed down consolidation reduction of an indicator of microcirculation and augmentation of indicators of components of a vascular tonus at the tenth days of a postoperative intervention becomes perceptible. Application of method LDF at fractures of long bones of extremities allows to supervise a current reparation process in the postoperative period and to expect possibility of development of disturbance of an osseous tissue at the stage of preclinical manifestations

This paper is devoted to the influence of constant transmembrane peritoneal dialysis during the systemic inflammatory response syndrome in patients with general purulent peritonitis (GPP). On the basis of comparative analysis of the results of staged surgical treatment of 67 patients with GPP the clinical efficacy of this method of the abdominal cavity was proved. As a result of constant transmembrane peritoneal dialysis has reduced the absolute risk of postoperative complications in the half-open run by BP at 23,0% and a relative on 27,1%
Percepções de licenciandos sobre avaliação de aprendizagens nos anos iniciais: um olhar sobre as observações
Authors: Marques Valéria Risuenho
Published: January 2021

Este artigo tem como objetivo apresentar os resultados do projeto de pesquisa intitulado "Percepções de Licenciandos sobre avaliação de aprendizagens nos anos iniciais do Ensino Fundamental" e discuti-los. O projeto foi desenvolvido na turma de Estágio de Docência II do curso de Licenciatura Integrada em Ciências, Matemática e Linguagens da UFPA. Quanto à avaliação formativa, ancoramo-nos em Fernandes (2008); sobre a concepção de que a avaliação precisa objetivar a melhoria das aprendizagens, assentamo-nos em Borralho, Lucena e Brito (2015) e no que diz respeito à proposição de práticas avaliativas formais e informais, em Mondoni e Lopes (2017). Metodologicamente, trata-se de uma pesquisa de caráter descritivo desenvolvida por etapas: estudos teóricos, observação, grupo de discussão e análise do material empírico. As análises das transcrições dos grupos evidenciam: prevalência de práticas que não consideram ensino-aprendizagem-avaliação como intrínsecas a um mesmo processo; práticas de ensino pautadas, sobretudo, no uso do livro didático; utilização da avaliação para classificar; uso da prova como instrumento avaliativo predominante nos anos iniciais; rara utilização de feedback; ausência de autoavaliação pelos alunos. Das percepções dos licenciandos, nota-se que embora os professores apresentem um discurso que sinaliza a utilização da avaliação formativa em suas práticas, as observações ainda identificam práticas avaliativas condizentes com características classificatórias, somativas.

O presente trabalho tem por objetivo identificar como informações históricas podem contribuir para a formação docente no que se refere ao conteúdo Razão Áurea. Dessa forma, no referencial teórico, discute-se sobre a relevância da postura investigativa do professor e as contribuições que a utilização da história da matemática propicia à formação deste profissional, bem como a respeito de alguns aspectos da Razão Áurea. Para tanto, foi realizada uma implementação que envolveu a utilização da história da matemática, a fim de trabalhar o conteúdo Razão Áurea com alunos do 4º ano do curso de Licenciatura em Matemática de uma instituição pública de ensino. Neste trabalho, o enfoque foi direcionado para o estudo dos mitos e verdades concernentes à Razão Áurea durante o planejamento da implementação, bem como para as discussões dos alunos em um momento posterior. A pesquisa é de natureza qualitativa, baseada na observação participante para coleta dos dados e na categorização mista, para análise do que fora constituído. Conclui-se que a utilização de informações históricas acerca do conteúdo Razão Áurea propiciou manifestações críticas, de modo que as professoras pesquisadoras e os alunos em formação inicial tiveram a oportunidade de desconstruir determinadas crenças impregnadas e disseminadas na história.

Devido a tantas mudanças abruptas que o mundo vivencia na atualidade, traz-se ao centro da cena, através desta pesquisa, alguns apontamentos reflexivos que se tornaram pertinentes como as desigualdades, as discriminações e os impactos sociais, além de transformações desencadeadas em tempos de pandemia da Covid-19. O objetivo geral da pesquisa está pautado em compreender como os grupos sociais em situação de rua e vulnerabilidade social da sociedade bragantina vivenciam a crise pandêmica. Como delineamento metodológico, se trata de uma pesquisa de abordagem qualitativa com os seguintes procedimentos: observação participante, rodas de conversa e análise interpretativa das narrativas orais. Entre os resultados obtidos permitiu-se conhecer parte destes grupos sociais que permeiam o locus da cidade, tal qual as múltiplas relações e ações que estes coletivos exercem, tornou-se ainda viável entender dentre quais maneiras eles concebem o que é a pandemia, a quarentena e a crise manifestada em suas vivências e ressignificações. Epistemologicamente, a pesquisa baseia-se em conceitos de Velho (1973); Lefebvre (2011); Santos (2020); Bauman e Donskis (2016), com perspectivas conceituais e analíticas sobre: antropologia urbana, relações sociais, invisibilidades de grupo e reflexões críticas acerca da pandemia de Covid-19.
