Aim: This study aims to investigate the neovascularization-inhibiting effect of topical nilotinib and to determine the effective dose of nilotinib.

Material and Method: In this study, 42 healthy Wistar albino rats were randomly divided into six groups. The left corneas of all rats except group 1 were cauterized with silver nitrate. Group 1 was the healthy control, with no corneal vascularization, which did not receive any treatment; Group 2 (sham) did not receive treatment, only topical DMSO; Groups 3, 4, and 5 received topical nilotinib at doses of 10, 20, and 40 μM three times a day, respectively; Group 6 received 5 mg/dL topical bevacizumab three times for a day for seven days. On the 8th day, photographs of the corneas were taken, and the percentage of corneal neovascularization area was calculated. Following all rats being killed via anesthesia, the corneas were removed to determine the levels of vascular endothelial growth factor (VEGF) and platelet-derived growth factor (PDGF) ELISA and corneal immune staining.

Results: Other than Group 3, the percentage of neovascular corneal area was lower in the treatment groups compared to Group 2 (p

Published: October 2022

Aim: Percutaneous endoscopic gastrostomy (PEG) is the preferred method for long-term enteral feeding of patients who cannot be fed orally for various reasons and have a functioning gastrointestinal system. In this study, we aimed to present and discuss the demographic characteristics, indications, and early and late complications of patients implanted with the endoscopic PEG in our center.

Material and Method: In this study, we retrospectively evaluated age, gender, chronic diseases, indication for PEG, complications during the procedure, complications arising from PEG during patient follow-up, and survival times of 84 patients who underwent PEG between January 2016 and January 2020 from the electronic medical file system.

Results: Of the 84 patients enrolled in the study, 59.5% (n=50) were male and 40.5% (n=34) were female. The mean age of the patients was 61.35±19.52 years. The endoscopic PEG success rate was 97.6%. Of the requests for PEG, 58.6% (n=50) were for patients in intensive care units. The most common indications for PEG insertion were cerebrovascular accident (CVA), chronic nervous system disease, and hypoxic-ischemic encephalopathy. Complications related to PEG were observed in 11 patients. All complications were mild, and no severe complications were observed. While one of the complications developed in the early period ( 30 days). No deaths from causes related to the PEG procedure have been observed.

Conclusion: In patients with inadequate oral intake, PEG is a safe and appropriate option for continuous enteral feeding because of its low complication and mortality rates.
A Rogue Planet Helps to Populate the Distant Kuiper Belt
Authors: Huang 黄 Yukun 宇坤 , Gladman Brett , Beaudoin Matthew , Zhang Kevin
Published: October 2022

The orbital distribution of trans-Neptunian objects (TNOs) in the distant Kuiper Belt (with semimajor axes beyond the 2:1 resonance, roughly a = 50–100 au) provides constraints on the dynamical history of the outer solar system. Recent studies show two striking features of this region: (1) a very large population of objects in distant mean-motion resonances with Neptune, and (2) the existence of a substantial detached population (nonresonant objects largely decoupled from Neptune). Neptune migration models are able to implant some resonant and detached objects during the planet migration era, but many fail to match a variety of aspects of the orbital distribution. In this work, we report simulations carried out using an improved version of the GPU-based code GLISSE, following 100,000 test particles per simulation in parallel while handling their planetary close encounters. We demonstrate for the first time that a 2 Earth-mass rogue planet temporarily present during planet formation can abundantly populate both the distant resonances and the detached populations, surprisingly even without planetary migration. We show how weak encounters with the rogue planet greatly increase the efficiency of filling the resonances, while also dislodging TNOs out of resonance once they reach high perihelia. The rogue’s secular gravitational influence simultaneously generates numerous detached objects observed at all semimajor axes. These results suggest that the early presence of additional planet(s) reproduces the observed TNO orbital structure in the distant Kuiper Belt.

Published: October 2022

Retinal diseases are among the leading causes of blindness and severe vision loss at the global level. Early diagnosis of retinal disease is of great importance in order to prevent irreversible damage to the eye. In recent years, deep learning methods have been widely used to diagnose retinal diseases. These models are developed for diagnosing a particular retinal disease. Most of these models detect and analyze disease features from the retinal image. Thanks to systems that can predict the detection of retinal diseases with high accuracy, it has allowed ophthalmologists to reduce their workload and reach more patients. This extensive literature review presents a comparative study of deep learning methods used to detect retinal diseases. For this purpose, the studies conducted on the subject between the years 2015-2022 will be examined. The related studies will be analyzed according to (1) rates of studies according to publishing years, (2) the data sets used, (3) the deep learning methods used, and (4) diagnosed retinal diseases.

Authors: Pramanik Dutta Sushmita , Saha Sriparna , Dey Aniruddha
Published: October 2022

COVID-19 is a pandemic caused by novel coronavirus. Molecular diagnostic tests and serologic tests are the two types of testing procedures currently available to detect virus of COVID-19 in the human body. Another way to detect COVID-19 is the use of chest x-ray. Radiology doctors use x-ray report to identify COVID-19-positive patients and the severity of that. In the proposed methodology, the authors develop an algorithm that can detect COVID-19 from chest x-ray images automatically. In the proposed work, image descriptor such as local binary pattern (LBP) is used to extract the features of the x-ray images. Using those textural pattern, LBP image of the original image is generated, and a meta-data has been curated. This modified dataset is given as input to the convolutional neural network (CNN) for classification of the images. The CNN identifies whether the x-ray image is of a COVID-19-affected person or a healthy person with accuracy measured as high as 92.24%.

Authors: Zhu Yulin , Yan Wei Qi
Published: October 2022

Parasitosis is a disease caused by parasites that could infect humans, animals, or plants. The parasites include mites, ascariasis, liver flukes, and malaria. The methods to detect parasites include pathological examination, immunological examination, and imaging examination. In this chapter, parasitic infections are detected from digital images acquired from a microscope, which will look for the possible infection caused by worms or eggs in a sample, such as mites and malaria. Rapid and accurate classification and detection of parasites will be very helpful for fast diagnosis and treatment. In this chapter, a malaria detection method is deployed by using deep learning based on TensorFlow and achieved 0.73 mAP@0.5IOU. Even if it does not seem to be a perfect performance, in the limited time and resources, the results are still valuable. The future work could port the model to mobile phones for image detection, which would bring much more convenience and portability.

Authors: Tanir Deniz , Karakas Asli Beril
Published: October 2022

Major depressive disorder (MDD) is one of the most frequent diseases in the mental and behavioral disorders group. Despite the fact that many diseases have been cured or eliminated as a consequence of technology and medical advances, the prevalence of major depressive disorder is quickly rising over the world. The structural brain abnormalities associated with severe depressive disorder have been widely studied using voxel-based morphometry. The MRICloud software has been used to process each subject's structural T1-weighted MRI scan. The classification model has been developed utilizing artificial intelligence (AI) algorithms to distinguish healthy and MDD patients. The study included 18 major depressive disorder patients and 19 healthy controls. Magnetic resonance imaging has been performed using 1.5 Tesla MR unit. As a result, MR images have been classified using AI algorithms to distinguish healthy and diagnosed with MDD patients.

Early Years Critical Literacies and Rights
Authors: Bittner Myles
Published: October 2022

Critical literacies as a field carries immense potential to provide students tools to build a better, more caring, and just world. This is especially true for students at the earliest years of education as they create the foundations for active citizenship in society. When these tools are connected to discourses that focus on equal treatment of all humans anywhere in the world, there is hope that future generations will actively resist long-standing systems of mistreatment. This literature review seeks to bring together two bodies of work and ponder at how they might work in relation to one another. This literature is then analyzed in relation to the physical location in which they take place to open understandings of how geopolitics, history, and culture impact what can and should be done. Critical literacies and discourses around human rights create complex intersections that share more in common than what might appear at surface level. Educators and educational policies should work to better understand these intersections to support the holistic development of any student.

Bat flies: source of supplement nutrients for an endemic Malagasy fruit bat
Authors: Ramanantsalama Riana Valéry , Ganzhorn Jörg U. , Vololona Judith , Goodman Steven M.
Published: October 2022

Among frugivorous vertebrates, the nutritional composition of consumed fruits often needs supplementing by other food types, such as leaves, pollen or invertebrates, to meet dietary requirements. The endemic Malagasy fruit bat, Rousettus madagascariensis (Pteropodidae), actively feeds on their dipteran fly ectoparasites, principally of the family Nycteribiidae and Streblidae, during grooming activities. Since bat flies take blood meals from their hosts, the consumption of these flies by bats might represent a mechanism of recycling and reducing the loss of important nutritional components, such as minerals or proteins and fatty acids. The contribution of these ectoparasites to the diet of R. madagascariensis is 4–10% of the daily protein requirements. This is an important proportion for a species considered to be exclusively frugivorous.
Deglaciation in central Labrador-Ungava as interpreted from glacial deposits
Authors: Kirby R P
Published: October 2022

The final dissolution of ice in Labrador-Ungava is now commonly regarded as having been in the vicinity of Schefferville. This paper presents some of the results of a study of the form and · origin of glacial deposits in the Schefferville area, and is
complementary to earlier studies of the glacial erosional features. The work involved detailed mapping of the glacial morphology and study of the fabric and composition of the deposits. The ground moraine reveals evidence of the last regional ice movement, which was from the north-northwest across
Schefferville, although glacial striations provide evidence of earlier movements from other directions. After weakening and cessation of ice movement, hummocky moraine forms and glacio-fluvial material were laid clown. This represents the final phase of deglaciation when the continental ice has
become climatically dead. lt disintegrated rapidly in situ with the final pieces melting on the floors of the larger depressions north of Schefferville.
Development and validation of a new robust RP-HPLC method for simultaneous quantitation of insulin and pramlintide in non-invasive and smart glucose-responsive microparticles
Authors: Emami Jaber , Haghighi Maryam , Rostami Mahboobeh , Minaiyan Mohsen
Published: October 2022

Background and purpose:

Since insulin and pramlintide cooperate in glucose hemostasis, co-administration and quantitation of them in pharmaceutical preparations are imperative. A simple, rapid, sensitive, and isocratic RP-HPLC method was developed and validated for simultaneous quantitation of insulin and pramlintide in loading and in-vitro release studies of a glucose-responsive system to improve the control of hyperglycemic episodes in diabetic patients.

Experimental approach:

The isocratic RP-HPLC separation was achieved on a C18 µ-Bondopak column (250 mm × 4.6 mm) using a mobile phase of water:acetonitrile:trifluoroacetic acid (65:35:0.1%) at a flow rate of 1 mL/min in an ambient temperature. Both proteins were detected using a UV detector at 214 nm. The method was validated for specificity, linearity, precision, accuracy, the limit of detection, the limit of quantification, and robustness.

Findings/Results:

Linearity was obtained in the concentration range of 30 to 360 μg/mL for insulin and 1.5 to 12 μg/mL for pramlintide. The results were validated statistically and recovery studies confirmed the great accuracy and precision of the proposed method. The robustness of the method was also confirmed through small changes in pH, mobile phase composition, and flow rate.

Conclusion and implications:

The method was found to be simple, specific, precise, and reproducible. It was applied for the determination of loading capacity, entrapment efficiency, and in-vitro release studies of insulin and pramlintide in a smart glucose-responsive microparticle. Co-delivery of insulin and pramlintide could be a new intervention in diabetes management and concurrent quantitation of these two proteins is, therefore, essential.

Authors: Darwish Rula , Almaaytah Ammar , Salama Ali
Published: October 2022

Background and purpose:

Antimicrobial resistance still constitutes a major health concern to the global human population. The development of new classes of antimicrobial agents is urgently needed to thwart the continuous emergence of highly resistant microbial pathogens.

Experimental approach:

In this study, we have rationally designed a novel conjugated ultrashort antimicrobial peptide. The peptide named naprolyginine was challenged against representative strains of wild-type and multidrug-resistant bacteria individually or in combination with individual antibiotics by employing standard antimicrobial and checkerboard assays.

Findings / Results:

Our results displayed that the peptide exhibits potent synergistic antimicrobial activity against resistant strains of gram-positive and gram-negative bacteria when combined with individual antibiotics. Additionally, the peptide was evaluated for its hemolytic activity against human red blood cells and displayed negligible toxicity.

Conclusion and implications:

Naprolyginine could prove to be a promising candidate for antimicrobial drug development.
Evaluation of the osteogenic effect of apigenin on human mesenchymal stem cells by inhibiting inflammation through modulation of NF-κB/IκBα
Authors: Asadi Azita , Goudarzi Farjam , Ghanadian Mustafa , Mohammadalipour Adel
Published: October 2022

Background and purpose:

Apigenin has stimulatory effects on osteogenic differentiation of human mesenchymal stem cells (hMSCs) as well as anti-inflammatory properties. This study investigated the osteogenic differentiation of hMSCs in inflammatory conditions treated with apigenin focusing on nuclear factor kappa-light-chain-enhancer of activated B (NF-кB), nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha (IκBα) and nucleotide-binding oligomerization domain, leucine-rich repeat and pyrin domain containing 3 (NLRP3) inflammatory pathways.

Experimental approach:

Along with osteogenic differentiation of the hMSCs, they became inflamed with lipopolysaccharide (LPS)/palmitic acid (PA) and treated with apigenin. Alizarin red staining, alkaline phosphatase (ALP) activity, and Runt-related transcription factor 2 (RUNX2) gene expression were used to determine the degree of differentiation. Also, gene expression of NLRP3 was performed along with protein expression of interleukin 1-beta (IL-1β), NF-кB, and IκBα.

Findings / Results:

Apigenin was shown to be effective in neutralizing the inhibitory impact of LPS/PA on osteogenesis. Apigenin increased MSC osteogenic capacity by inhibiting NLRP3 expression and the activity of caspase-1. It was also associated with a considerable decrease in the protein expression of NF-κB and IκBα, as well as IL-1β, in these cells.

Conclusion and implications:

The effects of apigenin on osteogenesis under inflammatory conditions were cautiously observed.

Exploring Ecosystems Health: Effects of Increments of Biodiversity and Trophic Complexity on the Stability of a Simple Gaian Ecosystem Model
Authors: Erlwein A.
Published: October 2022

The concept of ecosystem health is explored, deepening the analysis on the relationship between biodiversity and ecosystem stability, both as variables for health evaluation. Ecosystem stability is studied under a systemic approach in terms of resistance and resilience. According to some authors, when ecosystems´s models consider not only the effects of organisms on the environment but also feedbacks from the environment to the organisms, the interactions between biodiversity and ecosystem stability become positive or even synergic. To test this, the “Daisyworld” model is used to simulate the effects of diversity and trophic complexity increments on ecosystem stability. For this, the model was consecutively run with: 1st one species of daisy, 2nd two species of daisy, and 3rd two species of daisy and a herbivore. To study the stability of the system, three perturbations were introduced: 1st, 50% reduction on the daisy population, 2nd, 10% decrease on the solar radiation, and 3rd, 10% increase in the solar radiation regarding the initial value. From the execution of the model, it can be concluded that increments on biodiversity did result in more resistance but less resilience. Nevertheless, it is considered that the system becomes healthier, as its self-regulation is improved, and the total biomass (productivity) increased. However, increments in diversity or trophic complexity are themselves considered positive in evaluating the ecosystemic health.
Two kinds of behavior of fruit peel coagulant in treating low carbon source wastewaters
Authors: Fu Ying , Yue Qinghe , Luo Shuyuan , Tian Xi , Zheng Jiewen , Yang Yanting
Published: October 2022

Based on present serious phenomenon of insufficient carbon source in municipal sewage in China, the two kinds of effect of hybrid-fruit-peel (HFP) coagulant (coagulation and external carbon source (ECS)) on treating low carbon source wastewater was studied, mainly compared with that of sodium acetate (NaAc). The feasibility of HFP as an ECS was researched, and then its coagulation behavior, sludge properties, nitrogen removal were studied mainly with aeration mode and sequencing batch reactor (SBR), respectively. The results showed the ration of biochemical oxygen demand (BOD5) to chemical oxygen demand (COD) released from HFP was 0.67−0.76, within the scope of easily biodegradable. Within a short aeration time, HFP posed obvious coagulation behavior. HFP sludge gave larger extracellular polymer (EPS) and lower dehydrogenase activity (DHA) than NaAc. For HFP, much larger size sludge flocs appeared, the connection among the flocs became closer, and the biofacies and number of microorganisms (Opercularia Coaractata, Nematode, Vorticella, etc.) increased significantly. HFP can be used as an excellent ECS for low carbon source wastewater, and probably also have the ability of slow-releasing carbon, and can be applied to municipal sewage or other wastewaters with insufficient carbon source.

Published: October 2022

Background: The aim of this study was to investigate the elasticity of ocular structures in patients with mitral valve prolapse (MVP).

Material and Methods: This prospective study included a total of 35 patients with MVP (study group) and 35 healthy volunteers (control group). The elastography value of the ratio of orbital fat- sclera (ROF/S) was measured with real-time US elastography. For each eye, central retinal artery (CRA), posterior ciliary artery (PCA), and ophthalmic artery (OA) were evaluated, respectively.

Results: The mean ages of the patients in the study and the control groups were 31.77 ± 11.40 years, and 30.65 ± 7.45 years, respectively (P =0.511). Mean ROF/S were 1.95 ± 0.81 and 1.37 ± 1.06 (P=0.001) in the study groups and control, respectively. The mean RI of the OA was 0.67 ± 0.05 in the control group, 0.67 ±0.05 (0.55; 0.87) in study group. The mean RI of the PCA was 0.66 ± 0.05 in the control group, 0.68 ±0.06 in study group. . The mean RI of the CRA was 0.66 ± 0.05 in the control group, 0.66 ±0.06 in study group. The RI value was not a significant difference between control and study group (p > 0.05).

Conclusion: Scleral elasticity was significantly increased in MVP patients. These could be related to ocular pathologies such as glacouma, kerataconus in MVP.

Günümüzde teknolojinin hızlı şekilde ilerlemesiyle yenilenebilir enerji, havacılık, denizcilik, uzay, otomotiv, savunma sanayi alanlarında ve diğer alanlarda kullanılmak üzere hafif ve aynı zamanda üstün mekanik ve dinamik davranış özelliklerine sahip yeni malzemelere ihtiyaç hızla artmaktadır. Bu alanlarda kullanılan malzemeler, korozyon, yorulma, titreşim, yüksek sıcaklık, sürtünme ve yüksek gerilmelere maruz kalmaktadır. Dolayısıyla araştırmacılar ve bilim adamları bu ihtiyaçlara cevap veren ekonomik, daha yüksek mukavemetli, dinamik davranış özellikleri daha iyi olan ve daha hafif malzemelerin elde edilmesi için yapılan çalışmalara yoğunlaşmışlardır. Nanokompozit malzemelerin dinamik davranışlarının incelenmesi büyük bir önem arz etmektedir. Bu araştırmada nanopartikül katkısız (saf), nanokil ve nanosilika katkılı olmak üzere üç farklı cam elyaf takviyeli kompozit/nanokompozit malzeme vakum destekli reçine infüzyon yöntemi ile üretilmiş ve bu malzemelerin dinamik davranış özellikleri (Serbest titreşim doğal frekansları) deneysel olarak incelenmiştir. %3 nanokil ve %1 nanosilika katkılı kompozit malzemenin dinamik davranış özelliklerinin saf kompozit malzemeye göre söz konusu katkının malzemenin dinamik davranış özelliklerini ne oranda iyileştirdiği deneysel olarak araştırılmıştır. Çalışma sonuçlarına göre %3 oranında nanokil katkısının birinci ve ikinci doğal frekanslar üzerinde belirgin bir etkisinin olmadığı, daha sonraki doğal frekanslarda hatırı sayılır oranda bir azalmaya sebebiyet verdiği gözlenmiştir. %1 nanosilika katkısının ilk üç doğal frekans üzerinde minör de olsa bir artışa etkisi görülmüştür ancak, daha sonraki doğal frekanslar üzerinde ise azalışa neden olduğu görülmüştür.

Published: October 2022

The financial report is a report that presents data about the company's finances in a certain period. The importance of a financial report will be a trigger for company management to take various ways so that the company's financial statements always look good. This study uses agency theory, which is a theory that explains the relationship between shareholders (principals) and management (agents), where the agent is tasked with carrying out every order from the principal to improve company performance so that it can put pressure on agents to commit financial statement fraud. The sample of this research is infrastructure, utility, and transportation companies listed on the IDX during the 2018-2020 period, totaling 45 companies so as to obtain 135 research samples. This research was conducted with non-probability sampling technique and purposive sampling method. The tests in this research are pooling test and logistic regression analysis test. This study states that the variables of financial stability, nature of industry, and the ratio of total accruals have a positive and significant effect on the possibility of fraudulent financial reporting. The financial target variable has a negative and significant effect on the possibility of fraudulent financial reporting. Meanwhile, external pressure, ineffective monitoring, change in auditor, CEO's education, frequent number of CEO's pictures, and state-owned enterprises variables have no significant effect on the possibility of fraudulent financial reporting. Suggestions for further researchers are to add other independent variables such as personal financial needs, CEO duality, change in directors, and political connection as variables that can trigger financial statement fraud.

No âmbito desse programa, neste artigo, apresentamos alguns resultados significativos de uma atividade experimental investigativa implementada em uma escola pública, vinculada a rede estadual de Pernambuco, situada no nordeste brasileiro. Buscando aporte na teoria da aprendizagem significativa de David Ausubel (1918-2008) e no ensino por investigação, tomado como referencial metodológico, almejamos fornecer um relato parcial de uma experiência didática mais ampla envolvendo o tópico equivalente mecânico do calor. No entanto, embora parcial, tal relato transporta ensinamentos valiosos aos professores e professoras de Física, a saber, o uso de metodologias ativas nas salas de aula.

O aço carbono é conhecido por ser uma das ligas metálicas mais utilizadas na área industrial. Por ser resultado de dois elementos muito poderosos, o ferro e o carbono, esse material pode ser usado para a construção automóveis, máquinas, equipamentos, entre outras. O setor industrial no geral vem crescendo demasiadamente, tornando-se grande cliente deste tipo de aço, sobremodo em peças de fixação de alta responsabilidade como parafusos e outras peças que necessitam rigorosos testes para sua utilização. As aplicações dos aços na indústria envolvem uma série de análises e ensaios que podem permitir a prevenção e evitar problemas futuros e que comprometam no bom funcionamento do sistema. Os parafusos são feitos em uma larga gama de materiais, com muitas variedades de aço que são talvez os mais comuns. Com um formato cônico ou cilíndrico, sulcada em espiral ao longo de sua face externa e com a sua base superior adaptada a diversas ferramentas, tornam-se elementos de fixação de alta responsabilidade. A partir dos procedimentos metalográficos e ensaios de dureza Vickers, foram avaliadas a microestrutura e propriedades mecânicas de um parafuso fixador de fio de alta tensão, obtendo-se uma dureza de 247,58 HV. O ensaio de microdureza permitiu avaliar a dureza no microconstituinte perlita. Ao final, no ensaio de Energia dispersiva de Raios-X (EDX) foi analisada a composição do material estudado, apresentando 99,23% de ferro, 0,73% de manganês, 0,04% de zinco e 0,01% de cromo, considerado como aço ao carbono com alto teor de carbono, classificado como Aço SAE 1045.

A eletrodeposição é um processo simples e econômico a qual consiste no revestimento de ligas metálicas. Para que este processo ocorra de maneira satisfatória é necessário levar em consideração alguns pontos de suma importância no processo de deposição. O pH de uma solução eletrolítica, assim como a composição, pode interferir fortemente no revestimento de uma liga, além disso, a densidade da corrente, temperatura, agitação e tempo são um dos parâmetros que podem influenciar em uma deposição. Com base nisso, realizou-se um levantamento bibliográfico dos últimos dez anos, referentes as ligas de Ni-Co tendo como objetivo principal o estudo da influência do pH nos recobrimentos, como também as densidades de correntes e a composição dos banhos eletrolíticos. Diante do estudo realizado para as ligas de Ni-Co, observou-se que ao utilizar diferentes valores de pH o teor de Co aumenta gradativamente, sendo assim pode-se destacar que, em pH mais baixo, ou seja em meio ácido, tem-se uma formação maior de H+, e consequentemente a eficiência da corrente será menor. Quando se utiliza valores de pH mais altos, ou seja, meio alcalino, tem-se uma eficiência da corrente maior, pois a concentração de H+ será menor. Sendo assim, na eletrodeposição das ligas de Ni-Co, o teor de cobalto, aumenta a partir de pH mais altos e, consequentemente, a eficiência da corrente será maior quando se está em meio alcalino.

A charge é um recurso de linguagem que carrega consigo um método instigante e interativo com o intuito de passar informações de modo rápido e fácil. Como gênero textual é importante ressaltar que a principal função é expor a realidade por meio de imagens e textos, que geralmente abordam temas históricos de forma crítica, bem humorada e opinativa. Em vista disso, no contexto do ensino de ciências diversos autores vêm apresentando o grande potencial que as charges possuem no processo de ensino e aprendizagem, pois contribuem para o desenvolvimento de um pensamento crítico e sensibilizam sobre as temáticas científicas. Sabendo que o livro didático é em muitas vezes a única ferramenta que os docentes e discentes tem a sua disposição. Esta pesquisa tem o objetivo de analisar como as charges estão sendo utilizadas e empregadas nos livros didáticos de ciências aprovados pelo Programa Nacional do Livro Didático do ano de 2020. A metodologia utilizada neste estudo adota um caráter descritivo e exploratório baseado em uma abordagem qualitativa que visa identificar dados documentais não quantitativos. Neste estudo foi analisada a coleção de livro de ciências dos anos finais do ensino fundamental “Inspire Ciências”, da editora FTD. Como resultados identificamos 11 charges, que estavam distribuídas entre os quatros volumes. apesar do baixo número de charges encontradas nos livros didáticos, as mesmas quando utilizada como recurso pedagógico foram capazes de promover aos estudantes o conhecimento a outros universos, a discursos, e debates sobre a realidade bem como a sua expressão de opinião. Concluímos que apesar das charges não serem a panaceia do ensino de ciências, esperamos que esta pesquisa seja capaz de promover e despertar um olhar atento e diferenciado sobre a utilização deste recurso pedagógico em sala de aula.

"As plataformas digitais, tais como sites, aplicativos, jogos etc., permeiam as mais diversas atividades humanas no mundo contemporâneo. Este trabalho analisa as novas relações e a reestruturação da prática pedagógica a partir do impacto dessas tecnologias e da necessidade de inovações que colocam para professoras e professores. De tal modo, abordamos alguns conceitos e classificações das TIC, a repercussão no processo de ensino-aprendizagem, especificamente, focalizando o trabalho docente no ensino das ciências. A verificação empírica foi realizada através de questionário estruturado e envolveu a participação de professores atuantes em doze (12) escolas, entre públicas e particulares, situadas na área urbana do município de Campina Grande (PB). O levantamento revelou perfis professorais distintos, respectivamente, em escolas públicas e particulares. Nas primeiras, os docentes contam com longo tempo de vínculo com a unidade de trabalho e, em geral, são pós-graduados, enquanto que aquelas e aqueles que trabalham nas escolas particulares possuem menor tempo de vínculo e são graduados em tempo recente. Foram relatadas dificuldades importantes para o uso de softwares educacionais e aplicativos/jogos digitais, cujos problemas são compartilhados por profissionais de ambos os sistemas educacionais, contratando o amplo acesso às redes sociais com questões recorrentes como deficiências atribuídas à formação acadêmica e as deficiências de infraestrutura lógica e poucas oportunidades de capacitação para uso das tecnologias. Um achado encorajador verificou-se no uso da rede social YouTube pela imensa maioria dos professores públicos e privados, ratificando o encantamento e a versatilidade acrescentados pela visualização e produção de vídeos educativos."

Este artigo tem como objetivo investigar a utilização, relação e contribuição das tecnologias da informação e comunicação (TIC) no ensino de matemática na perspectiva do professor de matemática. A pesquisa é de caráter qualitativa e foi realizada em campo usando como instrumento de coleta de dados um questionário aplicado a dez docentes de matemática da educação básica do Estado da Paraíba. Após obter as informações, foi iniciada a análise dos dados, organizando cada resposta fornecida pelos docentes com base no referencial teórico estudado. Os professores evidenciaram que o software mais utilizado por eles é o GeoGebra e o conteúdo que os docentes aplicam mais as TIC são de geometria e função. Também foi notado que os professores consideraram as tecnologias da informação e comunicação (TIC) como recursos que auxiliam no ensino-aprendizagem de matemática, contribuindo de maneira efetiva para a construção de conceitos matemáticos, análise de comportamento dos gráficos e exploração e visualização da geometria. Além disso, os docentes enfatizaram que a relação das TICs com o ensino de matemática é algo positivo para o ensino-aprendizagem do estudante, pois facilita e dinamiza o ensino da matemática. Alguns participantes mencionaram que o planejamento e a estrutura de uma aula utilizando as TICs oferecem bons resultados, sendo necessário o professor romper com práticas que não contribuem para alcançar o objetivo da aprendizagem.

A Educação em Saúde e a Educação Ambiental apresentam diversas e diferentes abordagens teóricas e práticas que se constituem em tendências destes campos de investigação. A principal crítica à Educação em Saúde é centrada ao modelo biomédico, cujo foco é na imposição de hábitos e regras de saúde para a prevenção de doenças. Modelo este ineficiente, visto que não contribui para a mudança de comportamento, tampouco com a melhoria da qualidade de vida e bem-estar das pessoas. Na literatura nacional e internacional, são apresentadas variadas terminologias que adjetivam a Educação Ambiental. Pesquisadores e educadores do campo acabam por se aproximar de algumas vertentes, as quais, costumam estar relacionadas a aportes teóricos que embasam a pesquisa e a prática ambiental educativa. Essa pluralidade na configuração do campo contribui com a amplitude e complexidade na compreensão do acontecimento ambiental. Estendendo essa noção de pluralidade, argumenta-se que as várias perspectivas têm a potencialidade de aproximações e diálogos com outros campos do saber. Tendo isso em vista, o presente capítulo visa aproximar/discutir/articular/ vertentes do campo da Educação em Saúde e da Educação Ambiental que busquem objetivos e perspectivas teóricas que, apesar de surgirem em diferentes disciplinas, sejam epistemologicamente convergentes. Convergências que podem construir interfaces no enfrentamento de políticas neoliberais que desconstroem posturas alinhadas com a formação para uma vida cidadã, em relações de correspondência com a natureza, que busque equilíbrio entre corpo~mente~ambiente. Para tanto, por meio de um ensaio crítico, propõe-se a ampliação e a construção de novos conhecimentos à articulação entre estes campos de estudos e práticas.

Em uma sociedade cada vez mais globalizada e imersa em variados meios de comunicação, foi preciso admitir a necessidade de uma educação que, para além do ensino de conteúdos conceituais e procedimentais, também formasse cidadãos críticos capazes de refletir e tomar decisões de forma coerente e conveniente sobre as inúmeras demandas sociais, ambientais, tecnológicas, econômicas, políticas, éticas e morais que constituem o novo milênio. É neste contexto que o Ensino Baseado em Competências (EBC), amparado principalmente na chamada Pedagogia das Competências, surge no cenário internacional e brasileiro como alternativa para a construção e implementação de novos currículos e políticas educacionais mais condizentes com as necessidades e demandas da atualidade. Este trabalho tem o intuito de analisar e refletir sobre o processo de institucionalização do EBC no contexto educacional brasileiro. Para isso, realizamos uma pesquisa qualitativa de cunho bibliográfico onde buscamos analisar o contexto histórico, político, social e econômico das reformas ocorridas no sistema educacional brasileiro a partir da década de 90, fazendo um paralelo com o cenário europeu. Concluímos que as políticas educacionais brasileiras sofreram significativa influência dos organismos internacionais e multilaterais como a Organização para a Cooperação e Desenvolvimento Econômico (OCDE), e que a proposta do EBC implementado no Brasil apresenta significativas semelhanças em relação às propostas adotadas na Europa. Neste sentido, apresentamos algumas críticas e possibilidades do EBC a partir da realidade educacional brasileira.
