Authors:   , Ferreira Hugo Lagrimante
Published: November 2022

A presente pesquisa teve por objetivo elaborar um conjunto de tarefas, referenciadas teoricamente, para estimular os estudantes a produzirem significados sobre a desigualdade social associada a questões financeiras no Brasil. O estudo desenvolvido se insere na vertente de pesquisa em Educação Matemática denominada Educação Financeira Escolar cuja finalidade é a inserção do assunto na sala de aula de Matemática. As discussões sobre a desigualdade foram pautadas sobre as disposições sociológicas e as disposições socioeconômicas. A pesquisa é fundamenta teoricamente pelo Modelo dos Campos Semânticos e pela concepção de Educação Financeira Escolar proposta por Silva e Powell (2013). O processo de investigação baseou-se numa abordagem qualitativa de investigação que contou com uma pesquisa de campo como meio para recolha dos dados a partir da discussão de tarefas com estudantes do Ensino Médio, de modo a permitir orientar possíveis revisões de acordo com os objetivos fixados. A análise das ações enunciativas dos participantes evidenciou que os elementos propostos nas tarefas, tais como as noções de capital (econômico, cultural e social), habitus e tempo livre, foram amplamente debatidos, articulados e utilizados nas respostas dos estudantes estimulando também a inserção de outros elementos trazidos à discussão. Como resultado da pesquisa foi elaborado um produto educacional para uso dos professores em salas de aula.

Authors:   , Campos Erick Carvalho
Published: November 2022

A Internet das coisas (IoT) tem possibilitado a incorporação de sistemas de informação em toda a cadeia produtiva de alimentos, incluindo em unidades de alimentação e nutrição (UAN). Porém, a disponibilidade e o uso desta tecnologia para o monitoramento de temperatura em UANs, um ponto crítico para a garantia da qualidade das refeições produzidas nestes estabelecimentos, ainda são incipientes. Diante disso, neste estudo se desenvolveu e se avaliou um sistema IoT de baixo custo com tecnologia aberta capaz de automatizar o monitoramento da temperatura e da umidade de diferentes equipamentos presentes em UANs. O estudo compreendeu o desenvolvimento da infraestrutura completa contendo dispositivos para a captação dos dados dos equipamentos, rede segura para envio de dados, estrutura de sistemas na nuvem para análise, armazenamento e feedback de dados, assim como, a comunicação com os usuários. O sistema foi implementado em uma UAN e avaliado por 130 dias quanto a estabilidade em uso ininterrupto e a satisfação dos usuários. O artefato foi composto, na parte física, pelo microcontrolador NodeMCU com Tasmota 9.5.0.4 embarcado, conectado aos sensores DS18B20 ou AHT10 para mensurar a temperatura e a umidade, respectivamente. Os serviços Node-RED e Cloudant foram mantidos no IBM Cloud enquanto os serviços Mosquitto, InfluxDB e Node-RED foram mantidos na AWS para comparação destas opções de nuvem de baixo custo. Os dados foram disponibilizados aos usuários em um painel fixo composto de um monitor de 10" acoplado a um Rasbperry Pi 3B; uma interface web responsiva, um aplicativo para smartphone Android e pelo mensageiro Telegram (apenas para o envio de notificações). Todos os dispositivos funcionaram sem falhas, de forma estável e mostraram-se fisicamente robustos durante os testes. O custo de implementação e de manutenção de todo o conjunto em seis equipamentos distintos da UAN correspondeu a R$ 2.064,44. Nos quatro quesitos avaliados (facilidade de acesso às informações coletadas; satisfação com as notificações de ocorrências; a facilidade de uso do sistema; os benefícios proporcionados devido a implantação do monitoramento), 100% dos usuários se manifestaram satisfeitos (média 34,55%) ou muito satisfeitos (média 65,45%). Conclui-se que o sistema para implementação da tecnologia IoT constituiu uma ferramenta de baixo custo capaz de automatizar o monitoramento da temperatura e da umidade em UANs
Estudos envolvendo reações de azalactonas e alcalóides com a luz visível
Authors:   , Silva Larissa Pinto
Published: November 2022

A catálise fotoquímica tem sido amplamente utilizada como uma poderosa ferramenta de ativação de determinadas moléculas e na construção de novas ligações carbono-carbono que antes eram inatingíveis sob controle térmico, seu uso tem destaque nas reações de cicloadição e também na síntese de alcalóides. Neste trabalho é descrita a cicloadição [2+2] de azalactonas de Erlemeyer-Plöch utilizando a combinação da catálise de níquel com a catálise fotorredox e também foi iniciado o estudo da síntese total do alcalóide Melodinina K, utilizando como substrato o alcalóide pachysiphina. Na cicloadição [2+2] da azalactona foi utilizado fotocatalisador de irídio e catalisador de níquel para realização da catálise dual e foi obtido um produto o qual acreditava-se ser o cicloaduto assimétrico com os hidrogênios do ciclobutano na configuração cis, porém, a partir dos dados da análise de difração de raio-X do cristal do produto obtido, sugere-se que na verdade o produto seja o cicloaduto simétrico com as porções azalactônicas abertas e os hidrogênios do ciclobutano na configuração trans. A partir desse resultado, foram feitos alguns testes para avaliar se a utilização do níquel poderia trazer alguma vantagem nas reações de cicloadição da azalactona com diferentes catalisadores, mas nenhum resultado satisfatório foi obtido. No estudo da síntese total da Melodinina K, investigamos a formação do íon imínio, imprescindível para o desenvolvimento da síntese total, na tabersonina e na pachysiphina através da cianação fotorredox. A cianação fotorredox foi realizada na tabersonina, utilizando 2,5 mol% de fotocatalisador de irídio, 2 equivalentes de TMSCN em metanol, irradiado por LED azul de 60 W de potência por 6 horas, levando ao produto desejado com 89% de conversão e ótima seletividade. Já na cianação fotorredox da pachysiphina, utilizou-se 2,5 mol % de fotocatalisador de rutênio, 2 equivalentes de TMSCN em metanol, irradiado por LED azul de 30 W de potência durante 3 horas e meia, que levou ao produto desejado com 50% de rendimento, porém com baixa seletividade. Devido a impossibilidade de conseguir os substratos necessários para a continuidade dos testes, partimos para as tentativas de funcionalização da tabersonina cianada, mas não alcançamos nenhum resultado desejado.
Avaliação de diferentes técnicas de ativação da irrigação de canais radiculares na remoção da Smear Layer
Authors:   , Neves Alessandra Silva dos Santos
Published: November 2022

A remoção da smear layer é importante na descontaminação do sistema de canais radiculares, uma vez que permite uma melhor penetração das soluções irrigadoras nos túbulos dentinários. No sentido de otimizar a limpeza nas regiões de istmos, reentrâncias e porção apical do canal radicular, alguns dispositivos e técnicas têm sido desenvolvidos para uma melhor eficiência da irrigação. O objetivo deste estudo foi analisar seis técnicas diferentes de ativação da irrigação final quanto à capacidade de remoção da smear layer. Sessenta pré-molares inferiores com canal único foram selecionados, tiveram os canais instrumentados pelo sistema Reciproc R40 (VDW) e receberam uma irrigação final de 3ml de EDTA a 17% por 3 min. Em seguida, os dentes foram pareados e divididos em seis grupos de acordo com o protocolo de irrigação final (n=10): irrigação convencional (IC), ativação manual (AM), irrigação ultrassônica (IU), lima plástica Easy Clean (EC), XP Clean (XPC) e XP-endo Finisher (XPF). A capacidade de remoção de smear layer foi avaliada nos terços cervical, médio e apical por meio de microscopia eletrônica de varredura (MEV). Os valores dos escores atribuídos foram comparados entre os seis protocolos de irrigação utilizados aplicandose o teste ANOVA com desenho de blocos randomizados, com nível de significância de 5%. Os resultados mostraram não haver diferenças significativas entre os valores dos escores nos diferentes protocolos nos terços apical (p>0,05), médio (p>0,05) e cervical (p>0,05). Pode-se concluir que os protocolos de ativação utilizados neste estudo durante a irrigação final não apresentaram benefícios no que diz respeito a remoção de smear layer quando comparados com a técnica de irrigação convencional.
Impactos preliminares da COVID-19 nas operadoras de grande porte da saúde suplementar brasileira
Authors: Teixeira Isabela Tatiana , Alves Filho Alceu Gomes , Torkomian Ana Lúcia Vitale , Romano André Luiz
Published: November 2022

Introdução – Esse estudo aborda dados preliminares dos efeitos da pandemia da covid-19 nas empresas privadas de grande porte de assistência de saúde. Para efeitos dessa pesquisa, foram consideradas as 5 maiores operadoras médico-hospitalares do brasil.

Objetivo – Apresentar os resultados preliminares dos movimentos estratégicos das 5 maiores operadoras médico-hospitalares durante o período de pandemia da Covid19.

Metodologia – O trabalho utilizou informações oriundas de fontes secundárias, com análise de conteúdos de publicações e da base de dados históricos da ANS, bem como dados apresentados no site das próprias empresas (internet e intranet, para análise descritiva dos impactos preliminares da COVID-19 nas operadoras selecionadas para o estudo.

Resultados - Foi possível observar um discreto aumento no número de beneficiários das operadoras, e uma redução relevante na sinistralidade em 2020, em praticamente todas as empresas do setor. Diferentemente de outros anos, em que o crescimento de beneficiários era reflexo do aquecimento econômico nos setores produtivos no país, o movimento observado durante a pandemia está relacionado com o medo da população em não ter acesso aos recursos de saúde necessários caso afetada diretamente pela covid. A queda na sinistralidade tem relação com a redução no número de atendimentos médicos e de internações com procedimentos agendados, e impactaram na redução dos custos assistenciais.

Conclusões - Os efeitos da pandemia ainda são de curtíssimo prazo, e não é possível afirmar que os resultados econômico-financeiros obtidos em 2020 serão mantidos, e nem que as empresas analisadas não serão mais afetadas pela crise num futuro próximo, porém os resultados indicam que pontualmente a pandemia trouxe novos beneficiários e redução nos custos das operadoras analisadas.
Exploring Interdisciplinary Collaborative Online Learning Spaces through Sociomateriality in Cape Town, South Africa
Authors: Van den Berg Carolien , Verster Belinda
Published: November 2022

With the rapid adoption of online learning spaces since the advent of COVID-19, more and more calls are being made in higher education to move from emergency remote teaching and learning to appropriate online education. Although much has been written about the designing of online learning from both a technological and pedagogical perspective, limited contemporary literature is available to understand the complexity of interdisciplinary collaborative online learning. This limitation is investigated in this paper that reports on the first iteration of a Design-Based Research (DBR) study. Within this iteration, a qualitative exploratory research design that applies an inductive approach between researchers from Information Systems (IS) and Urban Planning (URP) is discussed. The aim was to develop design principles for interdisciplinary collaborative online learning spaces. This paper reports on the data generated during a semester-long, inter-institutional, interdisciplinary student project that was embedded in co-creating social digital innovations for pressing environmental problems faced by marginalised communities in Cape Town, South Africa. The participants for this study are 38 Honours degree IS students and 22 Advanced Diploma URP students (N=60). Participants, individually and in groups, completed a total of three reflective structured questionnaires using Google Forms during the semester that generated the dataset for this paper. The theoretical framing that underpins this research study is sociomateriality. The attraction to sociomateriality is its ability to not merely shift attention from the human to the non-human but rather a focus on entanglements and the interrelated nature of components that constitute the learning space. This focus on entanglements is needed for an understanding of the complexities associated with interdisciplinary collaborative online learning. Engaging this complex learning space through the data has revealed four design principles namely:   (1) creating immersive context-sensitive learning experiences, (2) designing opportunities to collaboratively (co)-construct knowledge, (3) focusing on the intra-action of socio-technical and socio-cultural entanglements and (4) foregrounding relationality as a tool to foster agency. It is argued in this paper that the aforementioned design principles are necessary for developing interdisciplinary collaborative online learning spaces that afford students a complex learning experience. Complex learning is considered fundamental in developing abilities in students to appropriately respond to the myriad 21st-century societal challenges that await.
Bitcoin as an Alternative Financial Asset Class: Relations Between Geopolitical Risk, Global Economic Political Uncertainty, and Energy Consumption
Authors: KEVSER Mustafa
Published: November 2022

The aim of this research is to investigate the causality between Global Economic Political Uncertainty (GEPU) and Geopolitical Risk (GPRT) and Bitcoin Energy Consumption (BTCE). In order to test the stationarity of the variables, the Lee-Strazich unit root test, which takes into account the structural breaks, was used, and the causality relationship between the variables was analyzed with the Hatemi-J (2012) causality test. Monthly data between May 2011 and February 2022 were used in the research. According to the results obtained from the research, geopolitical risk and global economic policy uncertainity are effective on bitcoin energy consumption. In addition, it has been determined that the negative effects of geopolitical risk and global uncertainties are more dominant. The results show that the demand for bitcoin, which is considered an alternative financial asset class, and accordingly bitcoin energy consumption, increases in case of global risks and economic uncertainties.
Software Development for the Use of Generalized Parabolic Blending in Data Prediction Processes
Authors: Üstünel Hakan
Published: November 2022

Parabolic blending (PB) is one of the important topics in applied mathematics and computer graphics. The use of generalized parabolic blending (GPB) for different scenarios adds flexibility to the polynomial. Overhauser (OVR) elements is a special case in GPB (r=0.5, s=0.5). GPB can also be used in estimation. In this study, data obtained from thickness distribution of a 3mm thick high impact polystyrene product after thermoforming using a mold was used for data estimation. For this purpose, software has been developed. The software development steps and formula usages are explained. Using the developed software, polynomials for GPB and default PB (OVR) were created. The data set was compared with the y values produced by the polynomials for certain x values. At the end of the research, it was determined that the results obtained from the GPB were 0.1728 percent more accurate than the data obtained from the PB for the default values.

Published: November 2022

Process mining in manufacturing is a newly expanding field of research in the application of data mining and machine learning techniques and the focus of business processes. Although it is an exciting subject of the recent past and business processes, sufficient research has not been done. Decision support systems such as enterprise resource planning, customer relationship management, and management information systems store the most valuable resource data of process details and event logs. In the advanced information systems of tomorrow, the process management, analysis, and modelling functions of modern enterprises will take their place as a necessity. As a requirement, the fundamental purpose of process mining in production is to refine data from event logs, automatically create process models, compare models with event logs, and improve and make development continuous. Our work is to contribute to application and research studies by drawing attention to process mining in the context of production. It is based on the literature review and primary stages of business process mining publications in the last decade with a production focus. An overview is discussed as a roadmap for future research with meaningful results.

Shell and tube heat exchangers are ideal for applications with extreme conditions of temperature, pressure and corrosive fluids. Its conformation consists of tubes, tube sheets, baffles, channel covers, connections and shell; these can take various forms, which will depend on the desired task, pressure drop, thermal stress, the need to prevent leaks, pressures, temperatures, fluid corrosion, and maintenance, among other factors. Each of the exchangers used in industries have advantages and disadvantages, for example; evaporators, vaporizers and boilers have almost the same operation since they work with liquid fluids that are superheated in order to convert the fluid into steam, but it should be mentioned that in the case of the first two, they work with liquid fluids of different nature. This paper shows the results obtained from the simulation with the COMSOL-Multiphysics® program in order to establish the appropriate variables for the operation of a heat exchanger, in addition to comparing the theoretical results and the results obtained with the simulator.

Authors: MARTÍNEZ-ÁNGELES Hugo , RÍOS-MORENO José Gabriel , PÉREZ-REA María de la Luz , TREJO-PEREA Mario
Published: November 2022

Low-density polyethylene (LDPE) is generally found in the form of bags that are used to pack or transport merchandise; however, the proper disposal of this non-biodegradable material has been a great challenge, since, worldwide, it is calculated that only 9%, of the 9 billion tons that have been produced so far, has been recycled. In Mexico, it is estimated that 8 million tons of this material will be generated annually and only 14% will be recycled. On the other hand, the recycling of these residues, as an aggregate in construction materials, is considered an environmentally sustainable application. The objective of this article is to develop a methodology for the design of ecological concrete bricks incorporating LDPE from design as part of its aggregates, which will be obtained from articles with results presented, thus seeking to analyze the best design; this as an alternative to bricks commonly found in the construction industry. Although bricks made only with LDPE and sand have given good results, in relation to the use of plastic in intervals of 25 to 50%, it is expected that by adding Portland cement, they will have better physical and mechanical properties.

Published: November 2022

Objective: To assess the risk factors for interstitial lung disease (ILD) in patients with rheumatoid arthritis (RA) and to evaluate the association of ILD with the use of methotrexate as well as with joint disease activity. Methods: A retrospective, cross-sectional study conducted between March and December 2019 at a tertiary healthcare center, in a follow-up of RA patients who had undergone pulmonary function tests (PFT) and chest computed tomography. We evaluated the tomographic characteristics, such as the presence of ILD and its extension, as well as joint disease activity. Functional measurements, such as forced vital capacity (FVC) and diffusing capacity for carbon monoxide (DLCO), were also assessed. After this, a multivariate logistic regression analysis was applied in order to identify risk factors associated with ILD. Results: We evaluated 1.233 patients, of which 134 were eligible for this study. The majority were female (89.6%), with a mean age of 61 years old and with a positive rheumatoid factor (86.2%). RA-associated ILD (RA-ILD) was detected in 49 patients (36.6%). We found an association of RA-ILD with age == 62 year, male sex, smoking history and fine crackles in lung auscultation and a decreased DLCO. The indicators of being aged = 62 years old and having moderate or high RA disease activity were both independent factors associated with RA-ILD, with an odds ratio of 4.36 and 3.03, respectively. The use of methotrexate was not associated with a higher prevalence of ILD. Conclusion: Age and RA disease activity are important risk factors associated with RA-ILD. Methotrexate was not associated with the development of RA-ILD in the present study.

Authors: Hailu Mekonnen
Published: November 2022

Food security issues become one of the critical concerns and top priority areas for Ethiopia. This study analyzed rural households’ food security status and its determinants in Minjar Shenkora woreda of Amhara Regional State and Ada’a woreda of Oromia Regional State. Data were collected from 240 randomly selected rural farm households. The study employed both descriptive statistics and a binary logistic regression model to estimate the status and determinants of households’ food security, respectively. The findings indicated that the average dietary energy available for food secured households was 2,860.6 kilo calorie per day while 1,891.7 kilo calorie per day for the insecure group. According to the findings of the binary logit model, factors such as education level, farm size, livestock ownership, cooperatives membership, off-farm income and credit access have positive and significant effects on household food security. While household size has a negative and significant effect on household food security. The results recommend that interventions should target at improving rural financial services and off-farm activities that increase households’ income and focusing on those most significant variables when attempting to enhance household food security.

Published: November 2022

Pendahuluan:  Cakupan IMD dan pemberian ASI Esklusif juga masih rendah. Informasi dari bidan diperoleh kebanyakan para ibu hanya memeriksakan kandungan pada awal kehamilan hanya untuk memastikan kondisi mereka. Beberapa ibu juga menyatakan bahwa mereka tidak merasa terlalu kuatir kerena sudah berpengalaman dengan kelahiran sebelumnya. hal ini mengindikasikan bahwa masih adanya ibu hamil yang belum mengerti sepenuhnya tentang betapa pentingnya kunjungan ANC secara teratur dan sesuai dengan standar yang ditetapkan, karena dengan memeriksakan kehamilan secara rutin pada kehamilan akan dapat menurunkan mortalitas dan morbiditas pada ibu hamil.

Metode: Metode yang digunakan adalah ceramah, diskusi dan tanya jawab dilengkapi dengan video dan menggunakan LCD.

Hasil: Meningkatnya pengetahuan ibu hamil sehingga nantinya proses kelahiran lancar dan bayi pun sehat, dan para ibu yang telah mendapatkan informasi yang tepat dapat menjadi influencer bagi masyarakat di sekitarnya untuk menggalakkan kepatuhan ANC dan pemberian ASI Eksklusif.

Kesimpulan: Meningkatkan pemahaman ibu hamil tentang pentingnya pelayanan ANC terpadu, pelaksaan IMD dan pemberian ASI Eksklusif
EDP-938, a new antiviral with inhibitory activity against the nucleoprotein of the respiratory syncytial virus
Authors: Reina Jordi , Iglesias Carla
Published: November 2022

The absence of an effective vaccine against respiratory syncytial virus (RSV) has led to the development of various drugs with the ability to inhibit or block its replicative activity. The first generation, called fusion inhibitors, bind to the protein on the viral surface and prevent the virus from binding and entering the cell. However, its low efficacy has determined the start of studies with second-generation compounds capable of binding or blocking the nucleoprotein (N); most of these compounds are analogs of 1,4-benzodiazepines. EDP-938 has shown high efficacy against RSV. The first trials in humans have shown that this antiviral is rapidly absorbed after oral administration and has a half-life of between 11-18 hours Administration for seven days of multiple oral doses of up to 600 mg/day or 300 mg/day/twice a day, there were hardly any significant adverse effects and the viral load in the lower respiratory tract decreased significantly.
Are you listening to me? Understanding children's rights through Hungarian pedagogic practice
Authors: Canning Natalie , Teszenyi Eleonora , Pálfi Sandor

Hungarian pedagogues agree that children should be listened to, have their rights recognised, and their voices heard.  The UNCRC recommends that children’s rights should be part of early childhood education, but this is not typical in Hungarian kindergartens and there is little pedagogical material to support the education of children about their rights.  This paper focuses on 5 kindergartens each typically accommodating over 150 children between the ages of 3-6 years old across Hungary. Six pedagogues worked with multi-age groups (4 kindergartens) and same-age groups (2 kindergartens).  The research adopted participatory methods to gather children’s views recognising them as valuable collaborators.  Children provided insight into their own lives through play based creative activities that focused on eliciting children’s thoughts and feelings.  Pedagogues collected video data using a ‘toolkit’ of children’s play activities during a 6-week period of the COVID-19 pandemic.  Pedagogues reflected on children’s play through a series of online focus groups with emphasis on how children expressed their views and preferences through play. Participants were encouraged to examine the power relationships between children and adults and analyse their role in knowledge production rather than knowledge extraction. Six themes emerged through thematic analysis, mapped to the 4 guiding principles of children’s rights: participation, survival, development and protection.  The findings highlight the juxtaposition between children’s life-as-experienced and life-as-told by adults; the skill of pedagogues to hear and sensitively interpret children’s voices based on their play and the challenge to slow down and reflect on practice.
The impact of education reform in Romania between 1989-2020 on the regulation and decentralization of early childhood education
Authors: Habinyak Erzsebet

Romania inherited a tightly controlled and strictly regulated mass education system from socialism, which inevitably has gone through a systematic reform. However, transformation or change of any education system does not take place for its own sake, but it is intended to meet certain social and political challenges and requirements. Therefore, the present study investigates the significant changes that have taken place in early childhood education (ECE) in Romania since the collapse of the Ceausescu regime in 1989. Specifically, the impact of the reform measures on ECE provision is examined in relation to curriculum content and structure. Explanation of how to investigate education have been central to the present research. The analysis of documentary data corpus identified three main themes reflecting the changes that took place: (i) the introduction of education reforms, (ii) the emergence of educational pluralism, (iii) the various iterations of the early childhood curriculum. Findings suggest that decentralisation processes led to the spread of alternative pedagogies in ECE add the findings about curriculum content change our investigation offers a detailed picture of the educational processes of decentralization and the changes it has brought in the early childhood curriculum.
Boarding schools in transition: A post-socialist analysis of “relevance” as an education policy problem in Mongolia
Authors: Dyer Caroline , Luke Anne , Sanjaa Narantuya
Published: November 2022

The rural boarding schools that were established in the socialist era to serve children in Mongolia’s herding communities remain integral to national policy for ensuring universal access to formal education. Education policy actors demonstrate commitment to the socialist legacy of the schooled herder child, while at the same posing legitimate questions as to boarding schools’ quality and contemporary relevance. This questioning is framed with reference to a globally-orientated discourse of standards, outcomes measurement and skills for employability. The paper argues from a post-socialist perspective that this orientation forecloses a nuanced, contextualised understanding of “relevance” as a complex educational policy problem. Drawing on policy documents and secondary literature, it develops and applies a post-socialist conceptual framework to explore the temporal and spatial orientations of rural boarding schools and their “relevance”. The analysis evidences multiple, intersecting layers of change which situate the schooled herder child and constitute Mongolia”s “unfinished business of socialism” in education. The paper concludes that the layering revealed in this analysis needs to be more visible to educational policy; and that to resist oversimplifying the complex problem of education”s relevance is an ontological imperative.

O modelo de desenvolvimento que se estabeleceu no espaço rural da Amazônia brasileira, com base em empreendimentos monocultores, tem gerado profundas transformações na vida dos camponeses. O presente artigo tem por objetivo discorrer, através do estudo de caso, sobre as transformações socioambientais que ocorreram a partir da implantação do megaempreendimento do cultivo da palma (Elaeis guineenses) no Assentamento Nazaré, que compreende terra tradicionalmente ocupada por famílias agricultoras no município de Acará, PA. Este é um estudo de cunho qualitativo, com pesquisa bibliográfica e trabalho de campo, para acompanhar a situação do igarapé Ipitinga e seus afluentes, a partir da realização de entrevistas com 13 agricultores do Assentamento. Pontua-se que o dendê, cultivado em larga escala, produziu danos nos cursos d’água e transformou o cotidiano desses camponeses, bem como alterou o uso dos recursos e a relação com a terra.
questão ambiental e o governo Bolsonaro

O objetivo deste texto é discutir as mudanças legislativas e o desmonte das instituições ambientais durante o atual governo federal brasileiro. Desde 2018, essas mudanças são parte de um processo de intensificação de danos ambientais e de promoção de violência contra povos indígenas, quilombolas, ribeirinhos e uma diversidade de populações do campo e da floresta. Este texto foi produzido a partir de uma revisão bibliográfica e da análise de documentos, legislações e notícias publicadas em diversas mídias nos últimos três anos. O recorte temporal compreende o ano de 2018 até 2022. Como resultados deste trabalho, indica-se que a orientação política do governo Bolsonaro, no que se refere à questão ambiental, é pautada pelo favorecimento da apropriação e espoliação dos elementos naturais do país e dos territórios pelo capital, a partir de uma experiência autoritária com traços neofascistas, formada por uma coligação entre determinados setores do exército brasileiro, do agronegócio, de grupos neopentecostais e transnacionais da mineração, do hidronegócio, dentre outros ramos de commodities.
IDENTIFICATION OF ENTRANT’S ABILITIES ON THE BASIS OF SUGENO-TYPE FUZZY INFERENCE SYSTEMS

In the conditions of effective training in aviation for dispatchers and pilots, it requires the use of infocommunication systems capable of working under conditions of fuzzy uncertainty in real time. The functioning of such systems is based on fuzzy inference systems. However, the development and implementation of these systems requires the creation of fuzzy knowledge bases. Therefore, special attention in this study is paid to the creation of a system of fuzzy inferences and the formation of a fuzzy knowledge base of this system. The result is a lozenge-type fuzzy inference system. The fuzzy knowledge base of the system contains the rules according to which, based on the results of test computer game problems of varying complexity, a conclusion is formed about the applicant’s ability to acquire knowledge and skills in a certain specialty.When developing the rules, both the results of passing different levels of professionally oriented computer test games were taken into account, and the interest of dispatchers and pilots was taken into account. Therefore, the proposed fuzzy rules of the knowledge base of the fuzzy inference system make it possible to assess not only the ability of the controller or pilot to solve certain problems. This dependence of the input dataset on time allows the implementation of a fuzzy inference system of the Sugeno type, using clear input data in the formation of inferences.

Extragalactic background light (EBL) studies have revealed a significant discrepancy between direct measurements—via instruments measuring “bare” sky from which Zodiacal and Galactic light models are subtracted—and measurements of the integrated galaxy light (IGL). This discrepancy could lie in either method, whether it be an incomplete Zodiacal model or missed faint galaxies in the IGL calculations. It has been proposed that the discrepancy is due to deep galaxy surveys, such as those with the Hubble Space Telescope, missing up to half of the faint galaxies with 24 ≲ m
AB ≲ 29 mag. We address this possibility by simulating higher number densities of galaxies, and so assess incompleteness due to object overlap, with three replications of the Hubble UltraDeep Field (HUDF). SourceExtractor is used to compare the recovered counts and photometry to the original HUDF, allowing us to assess how many galaxies may have been missed due to confusion, i.e., due to blending with neighboring faint galaxies. This exercise reveals that, while up to 50% of faint galaxies with 28 ≲ m
AB ≲ 29 mag were missed or blended with neighboring objects in certain filters, not enough were missed to account for the EBL discrepancy alone in any of the replications.
Double Shadows at the Lunar Poles

Published: November 2022

Topographic depressions within permanently shadowed regions (PSRs) on low-obliquity planetary bodies can be shielded not only from direct illumination, but also from scattered sunlight and thermal emission from nearby sunlit surfaces. We apply an illumination model to high-resolution topography data to produce the first map of double shadows at the lunar poles. The total doubly shadowed area resolved at the 30 m scale is 1.47 km2 in the northern hemisphere and 5.37 km2 in the southern hemisphere, predominantly contained within small craters on the floors of large permanently shadowed craters. In total, ∼0.04% of PSR area is permanently double shadowed, but the largest double shadows are nearly 600 m across, potentially large enough to be resolved in remote sensing temperature measurements. In the absence of secondary heating sources, double shadows are predicted to be significantly colder than singly shadowed areas and could sequester highly volatile compounds like carbon dioxide. Future in situ investigation of the regions identified in this work can elucidate the origin and distribution of the Moon’s most volatile deposits.

Anatomie de l’échec de l’État développeur en Afrique du Sud
Authors: Pons-Vignon Nicolas
Published: November 2022

Malgré la prégnance de la référence à l’État développeur dans les politiques économiques sud-africaines, personne ne considère à ce jour sérieusement le pays comme tel. Pire, la corruption qui gangrène les hautes sphères de l’Etat semble au contraire suggérer l’émergence d’un État prédateur. Cet article analyse l’Afrique du Sud post-apartheid au prisme du paradigme de l’État développeur. Les contraintes qui mettent en échec les politiques industrielles sud-africaines sont analysées à partir du cas d’un programme d’acquisition stratégique lié à d’importants investissements en infrastructure. Les impératifs néolibéraux, la restructuration de l’économie et la faible mobilisation gouvernementale en faveur de l’industrialisation obèrent l’émergence d’un État développeur en Afrique du Sud. Il semble, en réalité, qu’il n’y ait eu aucune tentative sérieuse de mettre en œuvre un tel État, et ce en dépit de la rhétorique du gouvernement.
