Authors: Felix da Silva Caroline , Estevo Azevedo Graziele , Franco Taketani Natália
Published: August 2021

RESUMO. A Doença de Parkinson é uma doença crônica, neurodegenerativa e progressiva onde não tem cura. Ainda há muitas investigações para se descobrir a causa da patologia. Em estudos recentes descobriram que pode ter uma relação direta com intestino, com a possibilidade de origem na microbiota intestinal e espalhando-se até o cérebro, com relação a uma desregulação no trato gastrointestinal. É reconhecido que, antes de aparecer os sinais e sintomas motores da doença, o organismo começa a sofrer alterações desde cedo, como a constipação intestinal, com o fortalecimento da hipótese de que a doença de Parkinson tenha início no trato gastrointestinal, e chegue até o cérebro através do nervo vago. Este trabalho pretende abordar sobre a microbiota intestinal e a sua conexão com a doença de Parkinson fazendo revisão de estudos e evidência de como sua composição no hospedeiro pode influenciar o seu metabolismo. A modulação da microbiota intestinal poderá, então, ser uma estratégia para o desenvolvimento de novas opções terapêuticas para o tratamento de doenças neurodegenerativas.

ABSTRACT. Parkinson's Disease is a chronic, neurodegenerative and progressive disease that has no cure. There are still many investigations to discover the cause of the pathology. In recent studies they found that it may have a direct relationship with the intestine, with the possibility of originating in the intestinal microbiota and spreading to the brain, with respect to dysregulation in the gastrointestinal tract. It is recognized that, before the appearance of the motor signs and symptoms of the disease, the body begins to undergo changes from an early age, such as intestinal constipation, with the strengthening of the hypothesis that Parkinson's disease starts in the gastrointestinal tract and reaches the brain through the vagus nerve. This work intends to approach the intestinal microbiota and its connection with Parkinson's disease, reviewing studies and evidence on how its composition in the host can influence its metabolism. The modulation of the intestinal microbiota could then be a strategy for the development of new therapeutic options for the treatment of neurodegenerative diseases.

Statement of the problem. The conceptual world picture of an author of a text is a key element to his/her understanding and correct interpretation. It helps to make conclusions about the author’s individual understanding of the world. The concept “way” is one of the basic concepts both in the Russian language and in the individual author’s pictures of the world, and is put on a par with such universal concepts as life, death, God, etc. The purpose of the article is to study the semantic content of the concept “way” in V.O. Pelevin’s novel “Yellow Arrow” and the ways of its lexical representation, identifying the features of the individual author’s picture of the world. Methodology (materials and methods). Research material consists of contexts verbalizing the concept “way”, extracted by continuous sampling from the text of the story “Yellow Arrow” by V.O. Pelevin. Basic analysis methods include descriptive and conceptual analysis, contextual and component analysis of lexical units, semantic analysis of dictionary definitions. Research results. In the aspect of verbal contextual representations, the concept “way” denotes a direction, a vector of development of human life in the novel: the common human route moves to the “destroyed bridge”. This idea is embodied in the lexemes of the near periphery (passengers, arrow) and the far periphery (knocking of wheels, low-style proper nouns). Not everyone can find an individual path, but the main character was able to “get off the train”.

Statement of the problem. The article discusses the peculiarities of YouTube video clickbait headlines. Some video makers are profit-conscious and deliberately headline their videos using eye-catching words that often have nothing to do with the real content in order to maximize the number of clicking the links. Such headlines aim at deceiving the recipients as for the content of the text or video, affecting their perception, attracting their attention and making them watch the video after all. Such headlines are known as clickbait, for they trap the reader or viewer with deliberately sensational or incomplete information. In this case promotional impact purposefully overrides the nominative function resulting in the peculiarity of the clickbait. The form of speech acts, including stylistic, lexical, syntactical, spelling and punctuation features, makes them stand out of other texts corpus. Particular attention is paid to discerning them as directive illocutionary acts and to proving that they meet all Searle’s requirements for such phenomena including illocutionary point, condition of sincerity, direction of fit. The purpose of the article is to analyze YouTube video clickbait headlines as directive illocutionary acts. Research methodology. The main method of research is qualitative content-analysis that involves revealing a specific meaning expressed with a clickbait headline as a significant element of a media text, as well as a communicative-pragmatic analysis aimed at identifying directive illocutionary force. Research results. Communicative success of clickbait headlines correlates with the “curiosity gap” manifesting itself in recipient’s information lacuna. The recipient should be able to bridge the former to avoid excessive cognitive attempts, clickbait headlines being a tool for that. Conclusions. Clickbait headlines analysis results in identifying them as directive illocutionary acts, for they foreground the perlocutionary function deliberately neglecting nominative one, thus manipulating an information recipient.
BILINGUALISM IN ESTONIA: POLITICS, EDUCATION, CULTURE, AND MENTALITY
Authors:   Moscow State Institute of International Relations, Volodina A.V.
Published: August 2021

In Estonia, there is only one official language. At the same time about 25–29 % of the population in Estonia considers Russian as their native language. The area of the Russian language in Estonia is located mostly in the northeastern county (Ida-Virumaa). Trying to integrate the region into the Estonian-speaking space leads to the building of Estonian-language cultural and educational institutions, while the country leaders seem to be ready to use the Russian language in the communication with Russian-speaking minority. At the same time, there is a tendency to reduce the share of Russian language education: opposition requires complete and immediate liquidation, while the government still insists on the gradual changes in the system, when there will be only a small number of Russian-language educational institutions. However, programs with partial teaching in Russian have remained at higher educational institutions, and some Russian-language conferences are still held at research centers. Estonia uses Russian speakers to attract foreigners who want to study Russian in Europe and to be taught by Russian native speakers. The Language Act regulates the correlation of Estonian and Russian in official institutions and the service sector. The Language Inspectorate constantly checks the compliance of services with the Language Act, at the same time infringing on the rights of the Russian-speaking population, which are also specified in the Framework Convention for the Protection of National Minorities. The popularity of recently appeared Russian-language channel ETV+ cannot be compared with Russian federal channels. At the same time, the appearance of the TV programs “My Estonias” and “My Truth”, which create dialogue between the communities, is a good sign. These programs were launched due to the cultural interaction, in which the theater played a role of a platform for negotiations between Estonians and Russians. The problems of the Russian-speaking population outlined in theatrical productions are also caused by its heterogeneity, since language is not an unequivocal sign of national identity.
PEASANT UTOPIAS OF THE ALTAI TERRITORY IN RUSSIAN PROSE OF 1960s–1980s
Authors:   Altai State University (Barnaul, Russia), Kozlova S.M.
Published: August 2021

In the late 1960s and early 1970s, the CPSU and the Soviet government, implementing a program of building communism in a short time, launched the process of industrialization of agriculture and proletarization of the peasantry. Writers of rural themes perceived this movement as a threat to the national identity of the Russian people and tried to contrast the state projects with the historical experience of the grassroots peasant initiative in creating rural communities of high productive labor, class equality, abundance, and original culture. The article considers two types of artistic models of the peasant world order: “closed”, focused on the centuries-old traditions of the Russian peasant community (V. Lichutin, V. Rasputin), and “open”, characteristic of the utopias of the Altai chronotope, focused on the post-revolutionary new peasantry order (S. Zalygin, V. Shukshin). The problem is in the degree of the utopian and the real in models of both types and their relevance in the modern search for the Russian way of revival and development of the peasant world. The scientific basis of this work is the research of the history and theory of the utopia genre and its modifications in Russian prose of the second half of the twentieth century: K. Chistov, Ya. Lurie, V. Shestakov, E. Shatsky, V. Grikhin, V. Chalikova, K. Parte, A. Gulygi, N. Tsvetnoy, N. Kovtun, A.

Statement of the problem. The interest of modern literary criticism to the problem of literature reflection is carried out mainly on the material of various metatexts, especially vividly represented in the turn of the century. The purpose of the article is to reveal author’s identity and artistic self-reflection in non-fiction texts. In this regard, the collection of articles entitled “How Do We Write”, compiled in 2018 by St. Petersburg writers Pavel Krusanov and Aleksander Etoev, is of particular interest. This book was written in reply to the book “How Do We Write” in 1930. The literary process of the 1920s, like, in many respects, literature of the new 21st century, was a period of renewal of various types and genres of artistic creativity, a period of the birth of new forms. Research results. Comparison of the two books, in which writers from different literary eras reflect on the nature of creativity, on the technology of literary work, on relationships with a reader, gives grounds to talk about the contours of a new textual criticism of the 21st century. Deformation of the canon, destruction of the boundaries of literature and aesthetic taste, and new forms of communication influenced the content and form of texts. Conclusions. With emergence of Internet reality, new sources of textual criticism appeared. The new literary reality dictates its own laws and creates new conditions for the development of publish- ing, writing, and reading relationships. Modern literature, like the literature of past years, reacts to cultural and historical events and to the development of the literary process, reflecting on the creation of the text and on the role of a writer here and now.
PROBLEMS OF CULTURE IN THE WORKS OF VSEVOLOD IVANOV
Authors:   A.M. Gorky Institute of World Literature of the Russian Academy of Sciences (Moscow, Russia), Papkova E.A.
Published: August 2021

Statement of the problem. The article is a continuation of our work devoted to the problems of the history of culture in the creative work of Vsevolod Ivanov in the 1940s–1960s. A new stage in the formulation of the problem, which makes it possible to trace the origins of the theme of culture in Ivanov’s creative work, became possible thanks to the publication of unknown texts by the writer of his early Siberian period. The purpose of the article is to analyze the theme of culture in Ivanov’s early work, to examine the evolution of the writer’s views. Methodology. The article uses comparative historical textual methods, the method of historical and cultural commentary. Research results. The theme of culture is considered for the first time on the material of Ivanov’s works of the 1910s, the evolution of his views is traced, which were formed in a dialogue with re- gional ideas and the concept of the East and West by A.M. Gorky. It is noted that the early works of the writer reflected anxiety for the fate of cultural values in the modern world. Particular attention is paid to the spiritual values of the culture of the East, understood by Ivanov in his own way and found embodiment in his work. The analysis of the story “The Return of the Buddha” and the third the edition of the novel “The Edessa Shrine” shows how the writer’s attitude to the East changed. Conclusions. The analysis of Ivanov’s works devoted to the theme of culture shows that this problem interested the writer from the very beginning of his creative path. Reflecting on the fate of the outgoing culture of Siberia in early works, dreaming of the possibility of the influence of the ancient East cultures on the historical choice of Russia and Europe in the 1920s, in the story “The Return of the Buddha”, the writer, by the end of the 1950s, obviously, comes to the conclusion that it is impossible for the forces of culture to resist the development of civilization.
Juvenile dermatomyositis in Thai children: Retrospective review of 30 cases from a tertiary care center
Authors: Nitiyarom Rattanavalai , Charuvanij Sirirat , Likasitwattanakul Surachai , Thanoophunchai Chaiwat , Wisuthsarewong Wanee
Published: August 2021

Background:

Juvenile dermatomyositis is a rare condition, but it is the most common idiopathic inflammatory myopathy in pediatric patients.

Aim:

To study the clinical manifestations, investigations, treatment, clinical course, and outcomes of juvenile dermatomyositis in Thai children.

Method:

This retrospective study included juvenile dermatomyositis patients treated at Siriraj Hospital, a 2,300-bed national tertiary referral center in Bangkok, Thailand, from 1994 to 2019.

Results:

Thirty patients (22 females and 8 males) were included with a female to male ratio of 2.7:1. Median age at diagnosis was 5.1 years (range, 2.6-14.8 years). Median duration of illness before diagnosis was 6.5 months (range, 0.3-84.0 months). Acute and subacute onset occurred in the majority of patients. Presenting symptoms included muscle weakness in 27/30 (90%), skin rash in 26/30 (86.7%), muscle pain in 17/26 (65.4%), and arthralgia in 4/18 (22.2%) of patients. Dermatologic examination revealed Gottron’s rash, heliotrope rash, and periungual telangiectasia in 25/30 (83.3%), 21/30 (70.0%), and 15/24 (62.5%) of patients, respectively. Interestingly, scalp dermatitis was found in 8/21 (38.1%) of patients. The most commonly used treatment regimen in this series was a combination of prednisolone and methotrexate. During the median follow-up of 3.1 years (range, 0.0-18.5 years), only one-third of patients were seen to have monocyclic disease. Extraskeletal osteosarcoma at a previous lesion of calcinosis cutis was observed in one patient at 12 years after juvenile dermatomyositis onset.

Limitations:

This was a retrospective single-center study, and our results may not be generalizable to other healthcare settings. Prospective multicenter studies are needed to confirm the findings of this study.

Conclusion:

juvenile dermatomyositis usually poses a diagnostic and therapeutic challenge, which can be compounded by the ethnic variations in the clinical presentation, as observed in this study. Asian patients tend to present with acute or subacute onset of disease, and arthralgia and/or arthritis are less common than in Caucasian patients. Scalp dermatitis is not uncommon in pediatric juvenile dermatomyositis patients. An association between juvenile dermatomyositis and malignancy, though rare, can occur.

This study aims to determine the factors that influence tobacco production and determine the level of efficient use of inputs on tobacco production factors. This research uses a stratified random sampling method with 63 farmers as respondents. The analysis used is multiple linear regression and calculation of economic efficiency. The results stated that the R2 value obtained through multiple linear regression analysis was 0.890, meaning that the contribution of independent variables (land area, number of laborers, number of seedlings, amount of TSP fertilizer, amount of ZA fertilizer, amount of ZK fertilizer, number of pesticides) to tobacco production was 89 percent, while 11 percent is influenced by other variables outside the model. The results of the F-test were jointly influential and the t-test showed variables that influenced tobacco production including land area, number of laborers, number of seeds, amount of ZA fertilizer, and amount of pesticides. Variables such as the amount of TSP fertilizer and the amount of ZK fertilizer had no significant effect. The use of production factors in tobacco farming has not been efficient. Keywords: Efficiency, Production, Tobacco.

People's activities that often upload photos of food before eating are common in popular social media, such as Facebook, Instagram, Twitter, and Pinterest. The food image data circulating on social media can be used for business purposes, such as analyzing customer behavior patterns. However, not all of the uploaded images are food images, so that before the analysis is carried out, it is necessary to do a classification task between food images and non-food images. Therefore, the researcher proposes automatic food image classification using transfer learning method using the Residual Network model version of 18 (ResNet-18). Residual Network model is used because it has a residual connection mechanism to solve the vanishing gradient problem. In addition, transfer learning was chosen because this method leverages the features and weights that have been generated in the previous training process on large and more general data (Imagenet) and thus reduce computation time and increase accuracy. The test was carried out by comparing the capabilities of the ResNet18 model with AlexNet. In addition, the fine tuning and freeze layer methods used to improve the quality of the model were also carried out in this study. In the experiment, the data set was divided into 3,000 images for training data and 1,000 images for test data, while the evaluation used was correctness accuracy. The results obtained in the ResNet18 model, namely the fine tuning training method, produced an accuracy value of 0.981 while the freeze layer resulted in the best accuracy value of 0.988. The AlexNet model that uses the fine tuning training method produces an accuracy value of 0.970 while the freeze layer produces the best accuracy value of 0.978. It can be concluded that the mechanism with the best accuracy is found in the RestNet18 architecture using the freeze layer 1-3 with an accuracy of 0.988.
Examining the Use of Electroencephalography for the Diagnosis of Alzheimer’s Disease and Mild Cognitive Impairment
Authors: Connor So Matthew , Abdallah Zahra , Du Jia Hui
Published: August 2021

Introduction: Alzheimer’s disease is a type of dementia characterized by a buildup of -amyloid plaques and neurofibrillary tangles. Prior to the development of Alzheimer’s disease, patients may experience mild cognitive impairment, characterized by a decline in cognitive abilities while maintaining independent function. Electroencephalography has shown promise as a clinical predictor of mild cognitive impairment. The purpose of this study is to review the existing literature on clinical biomarkers using resting-state electroencephalography or event-related potentials to differentiate Alzheimer’s disease or mild cognitive impairment from normal aging.
Methods: A search of primary research articles was conducted in PubMed. Selected articles examined mild cognitive impairment and Alzheimer’s disease utilising electroencephalography, event-related potential data, and resting-state data. Reviews, conference abstracts, and studies without human controls were excluded.
Results: Our search identified 100 and 125 records on resting-state and event-related potential data, respectively. The most common findings from resting-state studies included a reduction in alpha power, an increase in delta and theta power, a reduction in signal complexity, and differences in functional connectivity. The most common findings from event-related potential studies included reduction in P3 wave amplitude, as well as latency in both P3 and N2 waves.
Discussion: Resting-state and event-related potential electroencephalography studies indicate distinct changes in oscillatory brain activity and waveform shape which indicate distinct differences in MCI or AD compared to HC which may be clinically relevant.
Conclusion: There is evidence to support the use of certain electroencephalographic biomarkers for the diagnosis of Alzheimer’s disease or mild cognitive impairment. Future research should seek to examine how best to apply these findings in a clinical setting.
Barriers and Supports in Empowering Parents Care for Children with Cancer
Authors: Rasmita Dina
Published: August 2021

Cancer that occurs in children does not only affect children, but also parents. Parents experience anxiety, stress, fear of losing their children, and helplessness in caring for their children, so that parents are less than optimal in caring for their children. Parent empowerment can increase parents' knowledge, confidence, and ability to care for their children. Previous research found several obstacles to parent empowerment carried out by nurses so that parent empowerment was not optimal in its implementation. Knowing barriers and supports in implementation of parent empowerment in caring for children with cancer can support implementation of parent empowerment to be more optimal. The purpose of this study was to explore barriers and supports in parent empowerment in caring for children with cancer based on the nurse's perception. The design of this study was qualitative research design with a phenomenological approach. The data was collected by in-depth interview method using semi-structured interview guidelines on six nurses who were selected by purposive sampling technique. The data analysis was carried out by thematic analysis with the analysis stage according to Colaizzi. The results of this study were resulted in four themes, namely parental attitudes, parental characteristics, attitudes of nurses, availability of nurses and facilities. This study concluded that implementation of empowering parents to care for children with cancer became more optimal by knowing the barrier and supports in empowering parents care for children with cancer and nurses could make more effective planning in caring for children with cancer.

Published: August 2021

The problem of maternal mortality and morbidity in Indonesia is still become a big problem. In fact, the maternal mortality rate in Indonesia is still the highest in Asean. The factors above are the direct causes of maternal mortality. The causes of this death can be minimized by antenatal care which monitors the condition of the mother's pregnancy regularly to predict the risks that may arise so that preventive measures can be taken. The design used correlational research with a cross-sectional approach. The population in this research was all pregnant women aged 20-35 years who did antenatal care at Polindes Jatinom Kecamatan Kanigoro Kabupaten Blitar as many as 12 pregnant women. The sampling technique used accidental sampling. The sample was some of the pregnant women aged 20-35 years who did antenatal care at the time of the research as many as 12 pregnant women. Results: The result showed 67% was in the category of very satisfied and 75% of pregnant women had high motivation towards antenatal care. There was a correlation between the satisfaction of pregnant women on antenatal care services by midwife andÂ  motivation to do antenatal care proven by the results of the Spearman Rank statistical test which showed the value of sig = 0,000. Midwives are expected to maintain and keep the quality of service, especially in providing antenatal care to pregnant women so that the needs of mothers during antenatal care are always satisfied.
Movimentos político-epistêmicos na produção de histórias da formação de professores de Matemática em Mato Grosso do Sul

Published: August 2021

Este texto aborda resultados de diferentes pesquisas produzidas pelo Grupo História da Educação Matemática em Pesquisa (HEMEP) na Universidade Federal de Mato Grosso do Sul nos últimos dez anos. Trata-se de um exercício de análise de movimentações deste grupo na compreensão da formação e da atuação de professores de Matemática no estado, assim como de questões que cercam o conceito de escola. Três movimentos são destacados a partir dos trabalhos desenvolvidos no grupo de forma a evidenciar como os esforços coletivos têm-se deslocado entre uma historiografia dos acontecimentos com a produção de narrativas por meio da oralidade, uma política de narratividade que se evidencia nos jogos de linguagem e a prática de uma postura decolonial. Objetivos, discussões metodológicas e estéticas de escritas de diferentes dissertações e teses afirmam uma permanente movimentação em torno de uma historiografia menos explicativa e, assim, com mais potência de corte.

Authors: Novaes Barbara Winiarski Diesel , Pinto Neuza Bertoni
Published: August 2021

O objetivo deste artigo é discutir avanços e desafios do tema frações, identificados em pesquisas da História da educação matemática. Para tanto, examinamos quinze estudos recentes, publicados em eventos científicos e periódicos especializados, no período de 2019 a 2020. Tomando como parâmetro a distinção entre “ensino matemático das frações” e “matemática do ensino de frações” (MORAIS; BERTINI; VALENTE, 2021), as análises destacam avanços em estudos que apontaram transformações ocorridas na "matemática do ensino de frações” em diferentes períodos históricos. No campo da História da educação matemática, são ressaltados avanços decorrentes do uso de materiais estruturados para a matemática do ensino de frações, tal como os elaborados por Cuisenaire, dentre outros. Em relação aos desafios, verificou-se como mais proeminente o localizado no estudo de Valente (2020), ao recomendar a realização de pesquisas que contemplem análises de categorias como sequência, significado e graduação das frações, além dos exercícios e problemas envolvendo o tema e que são propostos aos alunos.
Currículos para formar professores que ensinam Matemática: histórias sobre a licenciatura em Matemática da Universidade Estadual de Feira de Santana nas décadas de 1970 e 1980
Authors: Ferreira Joubert Lima
Published: August 2021

Este artigo teve como objetivo compreender o processo de produção do projeto de curso da Licenciatura em Matemática da UEFS na década de 1980 por meio de discussões materializadas no currículo aprovado, com perspectiva voltada à dimensão pedagógica em relação aos currículos das Licenciaturas curta e plena em Ciências da década de 1970. Realizou-se uma pesquisa de natureza histórica, fazendo uso de documentos históricos localizados no acervo do arquivo do colegiado do curso de Licenciatura em Matemática da UEFS. Também se fez uso de entrevistas com ex-professores da universidade. No sentido atribuído por Hoffstetter e Schneuwly (2017), um processo de profissionalização, materializado nos currículos, expressou uma formação voltada ao bacharelado, tanto na habilitação plena do curso de Ciências quanto da Licenciatura em Matemática, amplamente caracterizada pelos saberes a ensinar, fruto da formação do corpo docente, até então especializado em determinados ramos da matemática; já a licenciatura curta em Ciências foi caracterizada por saberes para ensinar. Esses processos de profissionalização refletem o modo como as relações de poder se estabelecem dentro de institutos, centros e departamentos da área de Ciências Exatas, a partir de uma prevalência das disciplinas de referência na constituição do campo científico e do próprio processo de disciplinarização.

Published: August 2021

O artigo objetiva investigar a Matemática presente nas seções Mata Tempo Intelectual e Para o Grande Concurso, do periódico O Eco, editado pelo Colégio Anchieta de Porto Alegre, no século passado. Como o tema se insere na História da Educação Matemática no Rio Grande do Sul, este estudo qualitativo e documental ampara-se na pesquisa história. O público-alvo do periódico era a comunidade escolar e a mocidade católica brasileira, apresentando-se conteúdos religiosos e morais e de formação geral. A seção Mata Tempo Intelectual fez parte de 14 edições do periódico, nos anos de 1937 e 1938, enquanto a seção Para o Grande Concurso integrou oito edições de O Eco em 1938. Essas seções traziam perguntas, charadas e outras atividades de passa tempo relacionadas com diferentes áreas do conhecimento. A Matemática está envolvida em perguntas, valorizando o pensamento lógico-matemático do leitor, premiando assinantes do periódico com soluções corretas. Os conhecimentos matemáticos envolvem aritmética, geometria, álgebra, grandezas e medidas, com foco no desenvolvimento de habilidades para cálculo, raciocínio lógico e resolução de problemas. Assim, os editores do periódico buscavam despertar o interesse e a curiosidade da juventude estudantil, contribuindo para a formação da mocidade católica nos colégios onde O Eco circulava.

Authors: Sodré Gleison De Jesus Marinho
Published: August 2021

Este artigo objetiva evidenciar a problemática da transposição didática sobre a modelagem matemática financeira escolar a partir de versões dessa prática em fragmentos histórico-epistemológicos de obras de diferentes temporalidades. Para isso, descrevemos uma trajetória dessas práticas a partir de obras de diferentes contextos de produção social do cálculo de juros para o ensino, a fim de verificar a transposição didática dessa prática como produto de uma modelagem matemática específica à luz de recursos teórico-metodológicos da teoria antropológica do didático. Foram analisados fragmentos empíricos concernentes à formação inicial de professores a partir de problemáticas sobre o modelo matemático de financiamento em prestações fixas. Os resultados pontuados confirmam a hipótese da existência de uma prática social de modelagem matemática financeira que, em muitos aspectos, é preservada na instituição escolar. Esses resultados indicam possibilidades para responder, embora parcialmente, às problemáticas de interesse da teoria antropológica do didático, bem como estimulam futuras pesquisas sobre a história social de praxeologias para o ensino.

Affective Engagement of Higher Education Students in an Online Course
Authors: Daher Wajeeh , Sabbah Kifaya , Abuzant Maysa
Published: August 2021

The present research studies the factors that have impacted the affective engagement of university students in an educational online course. It examines how the type of interaction (learner-learner, learner-instructor, and learner-content) and the type of engagement (behavioural, cognitive and affective) have influenced the affective engagement of the students in the online course. Nineteen university students majoring in teaching mathematics, who were enrolled in the course Mathematics Teaching Methods, participated in the present research. Two data collection tools were used: semi-structured interviews and reflections. To analyse the texts resulting from the interviews and reflections, inductive and deductive qualitative content analysis was used. The research results indicated that university students have experienced more positive than negative affective engagement in the three communicational channels used in this course to facilitate online learning, which were: synchronous lectures, forums and assignments. The results also indicated that these three types of interaction have positively influenced students’ affective engagement in the three channels, with that influence being different from one channel to the other based on the interaction type taking place. We suggest that specific types of engagement need to be attended to for positive affect to occur. Doi: 10.28991/esj-2021-01296 Full Text: PDF

La volatilización es un proceso de pérdidas del nitrógeno y puede ser mayor según los factores edáficos, climáticos, la fuente y el método de aplicación. Este estudio se realizó en finca El Plantel, propiedad de la Universidad Nacional Agraria, coordenadas 12°06’23’’ de latitud Norte y 86°05’37’’de longitud Oeste en Masaya, Nicaragua. El objetivo fue cuantificar las pérdidas de nitrógeno por volatilización y su influencia en el rendimiento del cultivo de sorgo. Se evaluaron dos fertilizantes nitrogenados con dos métodos de aplicación en un diseño de bloque completo al azar con cuatro tratamientos y tres repeticiones. Los tratamientos fueron: urea 46 % aplicado en la superficie del suelo, urea incorporada al suelo, sulfato de amonio en la superficie y sulfato de amonio incorporado. La fertilización se realizó al momento de la siembra y a los 35 días después de la siembra. Los muestreos se registraron los días uno, tres, seis y nueve después de la primera fertilización y el segundo muestreo con la misma secuencia a partir del segundo día después de la segunda fertilización. Se realizó un análisis de varianza y separación de medias por diferencias mínimas significativas usando el programa INFOSTAT. En el primer momento se cuantificó mayor pérdida con el uso de urea al 46 % (8.86 kg de nitrógeno), y en el segundo período las pérdidas ascendieron a 57.68 kg N ha-1 cuando se utilizó urea en la superficie del suelo. Se obtuvo un mayor rendimiento del grano cuando el sulfato de amonio y la urea se aplican por debajo de la superficie del suelo.

Os acampamentos planejados são instalações que pertencem à categoria de abrigos transitórios e visam atender a população vítima de desastres naturais e/ou conflitos.  Este artigo propõe a elaboração de um sistema de catalogação de materiais, estruturas e tecnologias de acampamentos temporários planejados. O catálogo baseou-se em indicadores para escolha dos locais de implantação e da estrutura dos acampamentos. Elaborou-se uma lista com os acampamentos que se relacionam às principais emergências ocorridas no Brasil e no mundo. Como critério de seleção, adotou-se um intervalo temporal de onze anos. Dentre os acampamentos selecionados, utilizou-se como exemplo da proposta de sistematização, o acampamento de Zaatari, na Jordânia. Além disso, explicou-se a maneira que os catálogos serão inicialmente publicados no Portal Virtuhab e realizou-se algumas sugestões para a elaboração da futura plataforma denominada Infrashelter. A catalogação das soluções adotadas pode auxiliar no desenvolvimento e implementação de novos acampamentos planejados.
