Published: September 2021

An integration technology for wafer-level LiNbO3 single-crystal thin film on Si has been achieved. The optimized spin-coating speed of PI (polyimide) adhesive is 3500 rad/min. According to Fourier infrared analysis of the chemical state of the film baked under different conditions, a high-quality PI film that can be used for wafer-level bonding is obtained. A high bonding strength of 11.38 MPa is obtained by a tensile machine. The bonding interface is uniform, completed and non-porous. After the PI adhesive bonding process, the LiNbO3 single-crystal was lapped by chemical mechanical polishing. The thickness of the 100 mm diameter LiNbO3 can be decreased from 500 to 10 μm without generating serious cracks. A defect-free and tight bonding interface was confirmed by scanning electron microscopy. X-ray diffraction results show that the prepared LiNbO3 single-crystal thin film has a highly crystalline quality. Heterogeneous integration of LiNbO3 single-crystal thin film on Si is of great significance to the fabrication of MEMS devices for in-situ measurement of space-sensing signals.

Authors: Guo Shiliang , Li Xin , Guo Zechen , Zhao Xingtao , Meng Shuhan , Li Zhiquan
Published: September 2021

In this paper, we propose a polarization-independent optoelectronic modulator based on the electrical absorption effect of graphene. Firstly, we use the simulation software COMSOL Multiphysics to design the structure, and find via changing the applied voltage on both ends of the graphene that the equivalent refractive index of graphene can be changed, thus changing the light absorption capacity of the modulator. The waveguides in the transverse magnetic (TM) and transverse electric (TE) modes have almost the same extinction coefficient by making a double-layer graphene ridge structure in the center of the silicon-based waveguide, which can achieve approaching modulation depth in the TM and TE modes. At 1550 nm wavelength, the two-dimensional cross-section of the structure is analyzed by the FEM method using COMSOL Multiphysics to obtain the effective refractive index of the structure. The simulation results show that when the distance between the double-layer graphene isolation layer is d = 20 nm, the TE and TM modes can achieve extinction ratios up to 110 dB over the wide communication band by selecting appropriate “ON” and “OFF” switching points. The bandwidth is 173.78 GHz and the insertion loss is only 0.0338 dB.

Published: September 2021

Switchable mechanically induced changes in the wetting behavior of surfaces are of paramount importance for advanced microfluidic, self-cleaning and biomedical applications. In this work we show that the well-known polydimethylsiloxane (PDMS) elastomer develops self-patterning when it is coated with nanostructured TiO2 films prepared by physical vapor deposition at glancing angles and subsequently subjected to a mechanical deformation. Thus, unlike the disordered wrinkled surfaces typically created by deformation of the bare elastomer, well-ordered and aligned micro-scaled grooves form on TiO2/PDMS after the first post-deposition bending or stretching event. These regularly patterned surfaces can be reversibly modified by mechanical deformation, thereby inducing a switchable and reversible wetting petal effect and the sliding of liquid droplets. When performed in a dynamic way, this mechanical actuation produces a unique capacity of liquid droplets (water and diiodomethane) transport and tweezing, this latter through their selective capture and release depending on their volume and chemical characteristics. Scanning electron and atomic force microscopy studies of the strained samples showed that a dual-scale roughness, a parallel alignment of patterned grooves and their reversible widening upon deformation, are critical factors controlling this singular sliding behavior and the possibility to tailor their response by the appropriate manufacturing of surface structures.

Published: September 2021

Nonalcoholic fatty liver disease (NAFLD) is one of the most common liver diseases with no approved treatment. Zonarol, an extract from brown algae, has been proven to have anti-inflammatory and antioxidant effects. In this study, we investigated the role of zonarol in the progression of methionine- and choline-deficiency (MCD) diet-induced NAFLD in mice. After oral treatment with zonarol, a lighter body weight was observed in zonarol group (ZG) mice in comparison to control group (CG) mice. The NAFLD scores of ZG mice were lower than those of CG mice. Hepatic and serum lipid levels were also lower in ZG mice with the reduced expression of lipid metabolism-related factors. Furthermore, ZG mice showed less lipid deposition, less inflammatory cell infiltration and lower inflammatory cytokine levels in comparison to CG mice. Moreover, the numbers of 8-hydroxy-20-deoxyguanosine (8-OHdG)-positive hepatocytes and levels of hepatic and serum thiobarbituric acid reactive substances (TBARS) were significantly lower in comparison to CG mice. The expression levels of nuclear factor erythroid 2 related factor 2 (Nrf2), as well as its upstream and downstream molecules, changed in ZG mice. Zonarol could prevent the progression of NAFLD by decreasing inflammatory responses, oxidative stress and improving lipid metabolism. Meanwhile the Nrf2 pathway may play an important role in these effects.

Published: September 2021

Oleanolic acid (OA), a triterpene that is highly present in olive leaves, has been proposed as a component of functional foods for the prevention of metabolic syndrome, due to its anti-inflammatory activity. We analyzed the effects of OA on inflammatory parameters and signaling proteins in LPS-stimulated THP-1 macrophages. Thus, THP-1 macrophages were incubated with LPS for 48 h after pretreatment with OA at different concentrations. Pretreatment with OA was significantly effective in attenuating IL-6 and TNF-α overproduction induced by LPS in macrophages, and also improved the levels of AMPK-α. We also evaluated the effects of human triglyceride-rich lipoproteins (TRLs) derived from individuals consuming an OA-enriched functional olive oil. For this purpose, TRLs were isolated from healthy adolescents before, 2 and 5 h postprandially after the intake of a meal containing the functional olive oil or common olive oil, and were incubated with THP-1 macrophages. THP-1 macrophages incubated with TRLs isolated at 2 h after the consumption of the OA-enriched olive oil showed significant lower levels of IL-6 compared to the TRLs derived from olive oil. Our results suggest that OA might have potential to be used as a lipid-based formulation in functional olive oils to prevent inflammatory processes underlying metabolic syndrome in adolescents.

Dihydrosinularin (DHS) is an analog of soft coral-derived sinularin; however, the anticancer effects and mechanisms of DHS have seldom been reported. This investigation examined the antiproliferation ability and mechanisms of DHS on oral cancer cells. In a cell viability assay, DHS showed growth inhibition against several types of oral cancer cell lines (Ca9-22, SCC-9, OECM-1, CAL 27, OC-2, and HSC-3) with no cytotoxic side effects on non-malignant oral cells (HGF-1). Ca9-22 and SCC-9 cell lines showing high susceptibility to DHS were selected to explore the antiproliferation mechanisms of DHS. DHS also causes apoptosis as detected by annexin V, pancaspase, and caspase 3 activation. DHS induces oxidative stress, leading to the generation of reactive oxygen species (ROS)/mitochondrial superoxide (MitoSOX) and mitochondrial membrane potential (MitoMP) depletion. DHS also induced DNA damage by probing γH2AX phosphorylation. Pretreatment with the ROS scavenger N-acetylcysteine (NAC) can partly counter these DHS-induced changes. We report that the marine natural product DHS can inhibit the cell growth of oral cancer cells. Exploring the mechanisms of this cancer cell growth inhibition, we demonstrate the prominent role DHS plays in oxidative stress.

Published: September 2021

Calcium phosphate bone cement (CPC) is in the form of a paste, and its special advantage is that it can repair small and complex bone defects. In the case of open wounds, tissue debridement is necessary before tissue repair and the subsequent control of wound infection; therefore, CPC composite hydrogel beads containing antibiotics provide an excellent option to fill bone defects and deliver antibiotics locally for a long period. In this study, CPC was composited with the millimeter-sized spherical beads of cross-linked gelatin–alginate hydrogels at the different ratios of 0 (control), 12.5, 25, and 50 vol.%. The hydrogel was impregnated with gentamicin and characterized before compositing with CPC. The physicochemical properties, gentamicin release, antibacterial activity, biocompatibility, and mineralization of the CPC/hydrogel composites were characterized. The compressive strength of the CPC/hydrogel composites gradually decreased as the hydrogel content increased, and the compressive strength of composites containing gentamicin had the largest decrease. The working time and setting time of each group can be adjusted to 8 and 16 min, respectively, using a hardening solution to make the composite suitable for clinical use. The release of gentamicin before the hydrogel beads was composited with CPC varied greatly with immersion time. However, a stable controlled release effect was obtained in the CPC/gentamicin-impregnated hydrogel composite. The 50 vol.% hydrogel/CPC composite had the best antibacterial effect and no cytotoxicity but had reduced cell mineralization. Therefore, the optimal hydrogel beads content can be 25 vol.% to obtain a CPC/gentamicin-impregnated hydrogel composite with adequate strength, antibacterial activity, and bio-reactivity. This CPC/hydrogel containing gentamicin is expected to be used in clinical surgery in the future to accelerate bone regeneration and prevent prosthesis infection after surgery.

Published: September 2021

Antibiotic resistance has become a worldwide public health threat due to the rapid evolution and spread of antibiotic-resistant bacteria. CCG-211790 is a novel anti-virulence compound that does not kill bacteria but could ameliorate human diseases by inhibiting expression of virulence factors, thereby applying less selection pressure for antibiotic resistance. However, its potential clinical use is restricted because of its poor aqueous solubility, resulting in formulation challenges. Nanosuspension technology is an effective way to circumvent this problem. Nanosuspensions of CCG-211790 with two different particle sizes, NanoA (315 ± 6 nm) and NanoB (915 ± 24 nm), were prepared using an antisolvent precipitation-ultrasonication method with Tween 80 as the stabilizer. Particle and pharmacokinetics (PK) of CCG-211790 nanosuspensions were characterized. Both NanoA and NanoB demonstrated remarkable increases in dissolution rate compared with the bulk compound. The PK parameters of NanoA were comparable to those of CCG-211790 solution formulation in intravenous or oral administration, suggesting that CCG-211790 nanosuspensions with smaller particle size improved oral bioavailability and drug exposure compared to traditional formulations of drug candidates.

Published: September 2021

In this study, chitosan nanoparticles (CNPs) were prepared by the ionic gelation technique with tripolyphosphate (TPP), and the effect of CNP composition and physicochemical characteristics were evaluated. After the synthesis optimization, CNPs were used as carriers for a fish protein hydrolysate (FPH) with bioactive properties (CNPH). The physicochemical characteristics, antioxidant capacity and antimicrobial, antihypertensive and emulsifier properties of unloaded and loaded CNPs in a food system model were studied. CNPH showed a uniform particle distribution, size ~200 nm, high stability (zeta potential around 30 mV), radical scavenging activity and increased antimicrobial activity against Staphylococcus aureus, Shigella sonnei and Aeromonas hydrophila. Additionally, CNPH showed an angiotensin I-converting enzyme (ACE)-inhibitory activity of 63.6% and, when added to a food emulsion model, this system containing CNPs, with or without FHP, exhibited improved food emulsion stability. Thus, CNPs were able to carry the FPH while maintaining their bioactive properties and can be an alternative to the delivery of bioactive peptides with potential as an emulsion stabilizer for food applications.

Published: September 2021

Via the surface-grafting of carbon nanotubes (CNTs) with a silicon-containing flame retardant (PMDA), a novel flame retardant CNTs-PMDA was synthesized. The flame retardancy was tested by cone calorimeter. Compared with pure epoxy resin, the total heat release (THR) and peak heat release rate (PHRR) of epoxy resin containing CNTs-PMDA were significantly reduced, by 44.6% and 24.6%, respectively. Furthermore, thermal degradation behavior of epoxy resin based composite was studied by the thermogravimetric analysis with differences in heating rates. The kinetic parameters of the thermal degradation for epoxy resin composites were evaluated by the Kissinger method and Flynn-Wall-Ozawa method. The results suggested that activation energy values of epoxy resin containing CNTs-PMDA in thermal degradation process were higher than those of pure epoxy resin in the final stage of the thermal degradation process, which was closely related to the final formation of char layer residues. Finally, the results from Dynamic mechanical thermal analysis (DMTA) and Scanning electron microscopy (SEM) measurements exhibited that the functionalization of CNTs with PMDA obviously improved the dispersion of CNTs in the epoxy resin matrix.

A multi-objective optimization of in situ sol-gel process was conducted in preparing oil palm fiber-reinforced polypropylene (OPF-PP) composite for an enhancement of mechanical and thermal properties. Tetraethyl orthosilicate (TEOS) and butylamine were used as precursors and catalysts for the sol-gel process. The face-centered central composite design (FCCD) experiments coupled with response surface methodology (RSM) has been utilized to optimize in situ silica sol-gel process. The optimization process showed that the drying time after the in-situ silica sol-gel process was the most influential factor on silica content, while the molar ratio of TEOS to water gave the most significant effect on silica residue. The maximum silica content of 34.1% and the silica residue of 35.9% were achieved under optimum conditions of 21.3 h soaking time, 50 min drying time, pH value of 9.26, and 1:4 molar ratio of TEOS to water. The untreated oil palm fiber (OPF) and silica sol-gel modified OPF (SiO2-OPF) were used as the reinforcing fibers, with PP as a matrix and maleic anhydride grafted polypropylene (MAgPP) as a compatibilizer for the fiber-reinforced PP matrix (SiO2-OPF-PP-MAgPP) composites preparation. The mechanical and thermal properties of OPF-PP, SiO2-OPF-PP, SiO2-OPF-PP-MAgPP composites, and pure PP were determined. It was found that the OPF-S-PP-MAgPP composite had the highest toughness and stiffness with values of tensile strength, Young’s modulus, and elongation at break of 30.9 MPa, 881.8 MPa, and 15.1%, respectively. The thermal properties analyses revealed that the OPF-S-PP-MAgPP exhibited the highest thermally stable inflection point at 477 °C as compared to pure PP and other composites formulations. The finding of the present study showed that the SiO2-OPF had the potential to use as a reinforcing agent to enhance the thermal-mechanical properties of the composites.

Published: September 2021

A major challenge in tissue engineering is the formation of vasculature in tissue and organs. Recent studies have shown that positively charged microspheres promote vascularization, while also supporting the controlled release of bioactive molecules. This study investigated the development of gelatin-coated pectin microspheres for incorporation into a novel bioink. Electrospray was used to produce the microspheres. The process was optimized using Design-Expert® software. Microspheres underwent gelatin coating and EDC catalysis modifications. The results showed that the concentration of pectin solution impacted roundness and uniformity primarily, while flow rate affected size most significantly. The optimal gelatin concentration for microsphere coating was determined to be 0.75%, and gelatin coating led to a positively charged surface. When incorporated into bioink, the microspheres did not significantly alter viscosity, and they distributed evenly in bioink. These microspheres show great promise for incorporation into bioink for tissue engineering applications.

Published: September 2021

While the CuBi2O4-based photocathode has emerged as an ideal candidate for photoelectrochemical water splitting, it is still far from its theoretical values due to poor charge carrier transport, poor electron–hole separation, and instability caused by self-photoelectric-corrosion with electrolytes. Establishing synthesis methods to produce a CuBi2O4 photocathode with sufficient cocatalyst sites would be highly beneficial for water splitting. Here, the platinum-enriched porous CuBi2O4 nanofiber (CuBi2O4/Pt) with uniform coverage and high surface area was prepared as a photocathode through an electrospinning and electrodeposition process for water splitting. The prepared photocathode material was composed of a CuBi2O4 nanofiber array, which has a freestanding porous structure, and the Pt nanoparticle is firmly embedded on the rough surface. The highly porous nanofiber structures allow the cocatalyst (Pt) better alignment on the surface of CuBi2O4, which can effectively suppress the electron–hole recombination at the electrolyte interface. The as-fabricated CuBi2O4 nanofiber has a tetragonal crystal structure, and its band gap was determined to be 1.8 eV. The self-supporting porous structure and electrocatalytic activity of Pt can effectively promote the separation of electron–hole pairs, thus obtaining high photocurrent density (0.21 mA/cm2 at 0.6 V vs. RHE) and incident photon-to-current conversion efficiency (IPCE, 4% at 380 nm). This work shows a new view for integrating an amount of Pt nanoparticles with CuBi2O4 nanofibers and demonstrates the synergistic effect of cocatalysts for future solar water splitting.
Preparation of Emulsifier-Free Styrene–Acrylic Emulsion via Reverse Iodine Transfer Polymerization
Authors: Huang Tao , Gong Shuling
Published: September 2021

Styrene–acrylic emulsions containing hydroxyl functional monomer unit’s component are widely used for maintenance coating. In this paper, a stable emulsifier-free styrene–acrylic emulsion with solid content over 43% could be obtained in 210 min via reverse iodine transfer polymerization (RITP). By adding a mixture of methacrylic acid (MAA) and poly(ethylene glycol)methyl ether methacrylate (PEGMA) into a system containing a high content of hydroxyl functional monomer component (19.4 wt.% of the total monomer mass), styrene (St) could be copolymerized with methyl methacrylate (MMA); the modified film exhibited good hardness properties, good adhesive properties, and low water absorption. An increase in the amount of PEGMA decreased the glass transition temperature (Tg). When 1.4 times the reference amount of initiator was added, the highest molecular weight Mn could reach 40,000 g.·mol−1 with 0.25 times the reference amount of iodine in the emulsion. The largest tensile strength of the dried emulsion film over 5.5 MPa endowed the material with good mechanical properties. Living polymerization was proven by the kinetics of RITP emulsion and chain extension reaction. TEM micrographs manifest the emulsification of the seed random copolymer. This paper may provide a potential methodology for preparing polymer materials with excellent mechanical properties.

Authors: Pietro Granja Filippo Gian , Guaranys de Souza Leão Mateik Sophia , Franzen Anderson
Published: September 2021

Introdução: Permanece incerto qual é a melhor estratégia nutricional para indivíduos com diabetes mellitus tipo 2, pois há um cenário de inabilidade das recomendações atuais em controlar epidemiologicamente o avanço da doença. Objetivo: Analisar a eficácia nos marcadores metabólicos e peso corporal das dietas de baixo carboidrato com as dietas de moderado a alto carboidrato no tratamento de diabetes mellitus tipo 2. Material e Métodos: A metodologia PRISMA foi aplicada para identificar e analisar amostras de ensaios clínicos randomizados, de pacientes com diabetes mellitus tipo 2, comparando os efeitos de dietas de baixo carboidrato com dietas de moderado a alto carboidrato, em estudos com publicação posterior a janeiro de 1990. Resultados: Foram selecionados oito ensaios clínicos randomizados. Ambas as estratégias dietéticas reduziram de forma similar os valores da hemoglobina glicada, com uma tendência a melhora nas dietas de baixo carboidrato. Na maioria dos estudos a perda de peso, a redução nos valores de triglicerídeos, o aumento nos valores de HDL-c, a queda da glicose plasmática em jejum e as avaliações da ação glicêmica global contínua e da média de amplitude das excursões glicêmicas, foram maiores nos grupos das dietas de baixo carboidrato, demonstrando uma manutenção do perfil de glicose sanguínea mais fisiologicamente estável. Vale ressaltar, ainda, a predominância da diminuição no uso de hipoglicemiantes nos grupos sob uma dieta de baixo carboidrato, apresentada como importante vantagem no manejo do diabetes a longo prazo. Conclusão: As dietas de baixo carboidrato são seguras, bem toleradas e podem ser aceitas como opção de terapia nutricional para indivíduos com diabetes mellitus tipo 2.
Religion, Institutionalization and Legitimation of the Creed: Beyond Institutional Fundamentalism
Authors: Danner Leno Francisco , Bavaresco Agemir , Danner Fernando
Published: September 2021

This article argues that the association between institutionalization and strong epistemological, political, anthropological and ontological objectivity leads to institutional fundamentalism in three basic and problematic aspects for societal-cultural-institutional current dynamics: first, the institution’s centralization and monopolization of the constitution, legitimation and public foment of the creed, so that the institution becomes self-referential, self-subsisting and autonomous regarding common sense and common people, as opposed to other religious institutions; second, the institution’s vertical and direct affirmation and imposition on believers and non-believers of essentialist and naturalized foundations which do not seriously consider the differences as epistemological-political subjects, practices and codes; third, the institution’s self-affirmation of its special core-role in terms of linking Earth and Heaven, people and God, so that it becomes the one and supreme institution representing God on Earth, delegitimizing other religious institutions and popular practices as alternative ways to God, alternative ways of life and epistemological, political, anthropological and ontological grounding. From that point, the article advocates that only the weakening of the essentialist and naturalized foundations, the moderation or even the abandonment of their problematic parts, as the deconstruction of institutional self-referentiality, self-subsistence and autonomy regarding common sense and common people, as well as of the opposition between religious institutions one to each other, can tackle the problem of fundamentalism, enabling the valuing of differences as epistemological-political subjects and the performance of an ecumenical and pluralistic dialog-praxis which assembles all peoples into a same minimal project of global peace, justice and solidarity.
“Deus escolheu as coisas loucas deste mundo”: pentecostalismo, glossolalia e loucura
Authors: Quadros Eduardo Gusmão , De Sousa Neto Fabio
Published: September 2021

As relações de poder e saber demarcadas nas tensões entre pentecostais e os grupos herdeiros da Reforma são apresentadas em termos de diferenças epistemológicas. A rejeição da experiência pentecostal se assenta em pressupostos racionalistas que podem ser percebidos a partir dos conceitos foucaultianos e que revelam a suposta hierarquização do conhecimento questionada pela perspectiva analítica da decolonialidade. Esse artigo estuda discursos do movimento pentecostal onde a matriz cientificista é introduzida para depreciar ou para legitimar fenômenos religiosos marginalizados, a exemplo da glossolalia. Defende-se que não somente a epistemologia clássica foi trazida para o campo religioso no combate aos grupos subalternos, bem como esses próprios grupos incorporaram, a seu modo, a estrutura excludente do conhecimento científico.
Os fundamentos religiosos do Capitalismo e da Democracia e uma preocupação com a liberdade: um diálogo entre Tocqueville e Weber
Authors: Ferreira Matheus Gomes Mendonça
Published: September 2021

No campo da Ciência Política, a religião não se consolidou como um fenômeno analiticamente relevante para compreender as instituições políticas e seus atores. Atribuímos a isso o fato de que muitos dos efeitos que partem da religião incidem indiretamente sobre os fenômenos políticos.  A partir dessa reflexão, resgatamos o debate weberiano e tocquevilleano sobre o papel religião sobre o capitalismo e a democracia, tendo como essência uma preocupação com a liberdade humana. Conclui-se que, ao passo que em Tocqueville a religião possui algum poder de resguardar a liberdade humana, na leitura weberiana, isso não ocorre, pois ao se desprender de seus fundamentos, a religião se vê impotente diante na nova ordem social, de um novo tipo de dominação, o racional-legal.
Potência da razão e as limitações do ato humano: ciência é esponsalidade com o Criador
Authors: LOVO ODIRLEI ARCANGELO
Published: September 2021

A potência da razão e as limitações do ato humano, evidencia a necessidade de planejar, de prever, de expectar e de esperançar o futuro e, neste sentido, ser a ação necessária para realizar, em família, o mundo que se deseja. Essa capacidade de planejar e realizar precisa ser compreendida sob a perspectiva de esponsalidade com o Criador. Quando o ser humano se destoa da esponsalidade se torna demolidores do reino, obcecado por construir a Torre de Babel, fomenta a discórdia e absolutismos. A proposta de narrar o ser humano administrador e cocriador da obra de Deus, embasa-se nos documentos da Doutrina social da Igreja e nos documentos que elucidam a vida e vivência da família ‘moral familiar’. Pontua-se sobre as dimensões de sociabilidade, de economicidade e de parentalidade, sustentando ser está a base para que o ser humano administre a obra de Deus. A ciência possibilita a visão global da realidade, mas será uma visão livre e finita, e sem a perspectiva do Reino de Deus, condicionará as pessoas ao individualismo e a desrealização da unidade, em função dos projetos de domínio absoluto.
O conceito de cultura no cristianismo e suas implicações
Authors: Carvalho Leite Eliathan
Published: September 2021

O objetivo deste estudo é contribuir com elementos que tragam maior esclarecimento ao seguinte questionamento: Como, na História Cristã, o tema da cultura foi abordado? Busca-se explorar tal assunto a fim de compreender a realidade contemporânea e o desenvolvimento histórico do conceito. Para tanto, uma pesquisa de revisão bibliográfica e análise documental foi aqui efetuada. Assim, observou-se que o conceito de cultura, embora não trabalhado de forma sistematizada em alguns períodos, mantém uma compreensão geral de referência à identidade de um povo, formada por pressupostos diversos. A compreensão referente à importância desses pressupostos na definição da validade dessa cultura e na recepção cristã da mesma, contudo, é modificada ao longo da História.
Dionísio, Trickster, Exu e Diadorim como representação mítica-arquetípica-religiosa-poética
Authors: SILVEIRA LUIZ HENRIQUE LEMOS , Veliq Fabiano , Santos Clayton , Brito Sebastião
Published: September 2021

Este artigo tem como objetivo apresentar uma discussão sobre a experiência mítica-arquetípica-religiosa e poética das figuras de Dionísio (na cultura grega), Trickster (na cultura ameríndia), Exu (na cosmovisão ioruba) e Diadorim (na arte ou no imaginário brasileiros). Estes personagens apresentam características semelhantes, a partir de uma representação mítica-arquetípica presente em todos os tempos e lugares, como da fecundidade, da alegria e do teatro, do palhaço, do brincalhão astuto ou tolo, pregador de peças, trapaceiro. Não são vistos como heróis ou deuses da ordem, pelo contrário, são reconhecidos como anti-heróis e deuses da desordem, contudo, representam a mudança, a possibilidade do novo, da transformação.
Entender o passado e falar do presente: aportes a um Ensino Religioso descolonizador e pós-colonial
Authors: Borges Cristina , Nogueira Batista Paulo Agostinho
Published: September 2021

A relação entre religião e educação encontrou no Ensino Religioso Escolar – ERE uma forma de expressão. E o ERE sempre foi motivo de controvérsias há muitos anos. Hoje, reconhecido e integrado à Base Nacional Comum Curricular – BNCC (BRASIL, 2017) e tendo Diretrizes Curriculares Nacionais – DCN (BRASIL, 2018) para a formação inicial de professores, vive momento ímpar. Isso não significa que seus problemas desapareceram, ao contrário. A questão curricular continua sendo um desafio na superação de toda forma de proselitismo e de colonialidade, que ainda persiste, principalmente pela longa ausência de formação específica, hoje identificada nas Ciências da Religião. Partindo de análise bibliográfica, o objetivo do artigo é refletir sobre o ERE na perspectiva da descolonialidade e da interculturalidade, situando-o na BNCC, com suas competências e habilidades, para a construção da cidadania e de uma cultura de paz e da superação de toda forma de intolerância e exclusão.

E AGORA, PARA ONDE VAI? PROPOSTA DE ATIVIDADE DE ENSINO DE CARTOGRAFIA À DISTÂNCIA PARA ALUNOS DO ENSINO MÉDIO
Authors: Lana Morais Sérgio , Costa Alfredo , Laudares Sandro
Published: September 2021

Dado o contexto de excepcionalidade suscitado pela pandemia do vírus SARS-CoV-2, professores e alunos se reorganizaram para continuar seus estudos remotamente, o que implicou na reelaboração de metodologias de ensino e aprendizagem. Motivado pela necessidade de inovação das aulas de Geografia, este artigo tem como objetivo apresentar uma sequência didática para o ensino de cartografia a alunos do ensino médio em educação a distância e relatar seus principais resultados, tanto na perspectiva de sua capacidade de provocar aprendizagens significativas, quanto de sua capacidade de gerar engajamento. Desenvolvida a partir do Google Maps, Google Street View e Google Forms, e inspirada nas Corridas de Orientação, a atividade foi proposta para que os alunos pudessem vivenciar as lições aprendidas sobre a navegação em mapas em situações virtuais. Os resultados mostraram que a metodologia foi capaz de melhorar as habilidades de leitura e navegação de mapas dos alunos. Concluiu-se que os recursos de navegação virtual oferecidos pelas ferramentas de geovisualização podem ser apropriados como importantes aliados no ensino remoto de Geografia.

xamanismo ameríndio como tecnologia de relações
Authors: Da Silva Correia Wandreus Wilson
Published: September 2021

Este artigo tem o objetivo de fazer apontamentos acerca da natureza do xamanismo ameríndio; seus processos de criação; e como se torna o elemento cardinal das sociedades indígenas. Nessa abordagem serão articulados, principalmente, Mircea Eliade (1972; 1998), Lévi-Strauss (1975; 2008) e Viveiros de Castro (2007; 2009; 2014), como referencial etnográfico e teórico antropológico, de uma base estratégica que permita uma perspectiva atualizada para as Ciências das Religiões; ultrapassando, então, a análise da esfera ritualística, para se estender a um modo de vida intraespecífico.
