Published: December 2020

CHEMICAL MODIFICATION OF POLYPROPYLENE THROUGH THE INTRODUCTION OF SULPHONIC GROUPS FOR APPLICATION AS CATALYST IN ESTERIFICATION REACTIONS. In this work, the chemical modification of pristine polypropylene was carried out through sulfonation reactions with concentrated sulfuric acid (PPS1) and fuming sulfuric acid (PPS2), for production of heterogeneous catalysts used in esterification reactions. Fourier transform infrared spectroscopy, elemental analysis, degree of substitution and ion exchange capacity showed that both sulfonation agents were effective to promote the functionalization of polypropylene, with the fuming sulfuric acid capable of promoting a greater chemical modification. The materials catalytic activity in esterification reaction of oleic acid with methanol was evaluated at 100 ºC, methanol: oleic acid molar ratio of 78:1 and with 5 wt% of catalyst (referred to oleic acid weight). It was observed that reaction catalyzed by PPS1 converted 68.02% of oleic acid to methyl oleate in 3 hours of reaction, while PPS2 reached 86.47% conversion in five hours, showing even greater catalytic efficiency than the commercial ion exchange resin, Amberlyst 15. Therefore, the conditions employed for the sulfonation of polypropylene were satisfactory to produce materials with acid characteristics necessary to catalyze the esterification reaction of oleic acid with methanol.

OPTIMIZATION AND VALIDATION OF A SIMPLE AND LOW-COST SEMI-QUANTITATIVE ENZYMATIC METHOD TO SEARCH FOR CISTEINE PROTEASES INHIBITORS. Cysteine proteases are an important class of enzymes involved in several essential biological processes. For this reason, these enzymes are important therapeutic targets, and therefore can be used in enzymatic assays for the search of hits. The most widely used methods in the search of enzyme inhibitors are spectrophotometric, however they have relatively high operational costs. For this reason, simpler, and cheaper methods can be useful in the search for enzyme inhibitors. In this work, a simple and low-cost semi-quantitative method was optimized and validated using papain and skimmed powdered milk (casein) as a substrate. The ideal condition for the method was the one that used powdered milk, 0.250%, papain solution, 9.4 mg mL-1 and incubation time, 18 h. The method validation was performed using the inhibitor E64 and herb extracts, in different concentrations. After carrying out the experiments and statistical analyses, a high reproducibility can be observed, with relative standard deviations below 2.1%. Plant extracts were used to test the method and the results indicated that these extracts are promising for the search of cysteine protease inhibitors. The method developed here has simplicity and reproducibility and has great application, as preliminary study, in the search for inhibitors of cysteine proteases.

Authors: Tolouei Sara E.L. , Curi Tatiana Z. , Klider Lislaine M. , Junior Arquimedes G.
Published: December 2020

Cardiovascular diseases (CVDs) are a group of non-communicable disorders of the heart and blood
vessels. Although lifestyle changes as well as pharmacological treatments and surgical interventions are available
in many countries, CVDs are still considered the number one cause of mortality worldwide. Hence, considering
that most CVDs are caused by genetic and environmental imbalances, micro-RNAs (miRNAs or miRs)
appear as a plausible therapeutic option for CVDs as they are able to regulate a wide number of genes due to
multiple target sites in different genes. Since miRNA-30 and -145 have been shown to play critical roles in the
cardiovascular system, acting as important regulators of many functions and biological processes, this review
focuses on summarizing recent findings on their involvement in CVDs, mainly as targets for therapeutic intervention.
Therefore, the biology, mechanisms of action and data on what has been discovered so far regarding
miRNA-30 and 145 as therapeutic targets for CVDs are presented.
Autosomal Recessive Hereditary Spastic Paraplegia: A Rare Case of a Family with Phenotypic Variation
Authors: Saban Mor , Shachar Tal
Published: December 2020

Background:

Hereditary spastic paraplegia is a neurodegenerative disorder
with a pure and complex form. More than 50 genetic types are currently known, with different
ages of onset for characteristic symptoms. Data regarding hereditary spastic paraplegia
remain scarce, and the rare subtype of spastic paraplegia type 5 is no exception.

Objective:

This report presents data regarding the case of a single family, from the city of
Djerba, with five individuals affected with hereditary spastic paraplegia, the largest number
of spastic paraplegia type 5 mutated family members so far reported in current literature.

Methods:

To emphasize the importance of genetic testing, we retrospectively reviewed a
familial confirmed case of hereditary spastic paraplegia. Clinical features of family members
were described.

Results:

The family presents a large phenotypic variation that, in part, differs from the
known phenotypic presentations. Age of onset and clinical manifestation showed interfamilial
variations. The alteration found in CYP7B1 (c.1081C>T; p.R361*) may help emphasize
the importance of genetic testing and the much-needed treatment options already
in use in current neurological practice.

Conclusion:

The understanding of the molecular pathways of hereditary spastic paraplegia,
together with the establishment of disease biomarkers, will hopefully lead to better
and more personalized treatment.

Authors: Nooreen Madiha , Fatima Shafia , Nagarapu Raju , Khan Mazharuddin Ali , Khan Aleem Ahmed
Published: December 2020

Osteoporosis is a chronic disease characterized by decreased bone mass and
distorted microarchitecture that leads to increased bone fragility making an individual
prone to fractures. It is one of the most widely affected diseases worldwide that has the
potential to cause serious morbidity, mortality and cost implications. It is a multifactorial
disease that is influenced by the interaction between genetic, hormonal, nutritional and
environmental factors. As it is a polygenic disorder, myriad genes influence the disease
condition to a varied extent. The identification of genes or loci that effects the development
of the disease will help not only in individualizing the prognosis, treatment and prevention
of fractures but also in discovering novel therapeutic agents. The genetic association
studies on osteoporosis have reported conflicting results. Well designed and efficiently
conducted studies with enough power to detect variations in the interaction between
various contributing factors of the disease in the homogenous population are needed to establish
conclusive genotypic associations with the disease. The present review briefly
summarizes the data published on the genes affecting osteoporosis development.
New research methods of Sales-Marketing Interfaces
Authors: Hetényi Gábor
Published: December 2020

The energy invested in research in this topic is justified by the fact that the lack of optimal integration between SM (sales-marketing) can negatively affect overall corporate efficiency. The aim of this article is to present possible research methods that can reveal the impact of selected indicators, such as information exchange, coordination, vision and communication, conflicts, on the operation of the SM interface, according to Hungarian and foreign employees of international companies, and how they affect sales and marketing collaboration between pharmaceutical companies (PMC) and non-pharmaceutical companies (NPMC). It also attempts to demonstrate how the Partial Least Square (PLS) path modeling technique can provide valuable information on the consequences of management activity, and how the methods provided by Voyant Tools provide further research through quantitative analysis of qualitative data on the marketing sales interface (SMI), they can open up opportunities. The PLS-PM modeling technique was used to explore the relationships between the selected factors and possible hidden variables. These results clearly demonstrate that there are factors that influence SM collaboration that operate differently in PMCs and NPMCs, and that nationality differences can have a significant impact on how employees evaluate factors that affect SM collaboration. Of the methods we selected by Voyant Tools, the t-SNE (t-Distributed Stochastic Neighbour Embedding) tool proved to be the most sophisticated analysis, allowing the deepest analyzes by exploring relationships between groups of terms.

Published: December 2020

Áttekintve az utóbbi 10 év szakirodalmát, amely a vállalati beruházások és a finanszírozásuk kockázatainak kezelése kapcsán íródtak, jól látható az, hogy a kockázatkezelést és a problémamegoldást a holisztikus közelítés és a komplex problémakezelés hatja át napjainkban. A likviditási, finanszírozási és beruházási kérdések együttes vizsgálata lényeges, hiszen egy-egy döntés mindegyik területre hatással lehet, együtt befolyásolva a vállalati értéket. A beruházások vonatkozásában az értéknövelés a beruházás által generált cash-flowk simításán keresztül érvényesíti hatását. A vállalati pénzügyek területe az empirikus elemzésekben jól megfigyelhető módon élesen nem választható el a gazdálkodástudomány más területeinek kérdéseitől, sőt műszaki témáktól sem, mint ahogy a kockázatkezelésről is, jó ideje, integrált formában gondolkodnak. A fedezeti ügyletek (mind a pénzügyi, mind a működési) használata nélkülözhetetlenné vált a vállalatok menedzsereinek eszköztárában. A válság következményei számos olyan tanulmányt ösztönöztek, amelyek minderre igazolásul szolgáltak. Nagy figyelem jutott a tranzakciós költségekre, beleértve a szerződések költségeit illetve az ügynökköltséget, illetve az információs aszimmetria miatti veszteségeket. A viselkedési pénzügytannak főként a menedzseri döntéseket illető megállapításai szintén lényeges adalékot képeznek e területen.

Published: December 2020

The essential objective of the proposed suspension framework is to limit the undesired disturbance of a vehicle because of uneven surfaces on streets. This framework in vehicles is comprise of some fundamental components like dampers and springs which ingests the stuns that are instigated by unusual streets. In any case, these frameworks can just work up to a predefined constrain. Vehicle suspension frameworks are planned by taking the solace capacity of a traveler in record and to enhance the street grasp on each surface.
This examination proposes an idea for structuring a superior suspension arrangement of vehicles to upgrade the nature of the drive without corrupting the dependability of the vehicle plan. In this exploration, a mix of two suspension framework is presented in which one goes about as an essential suspension while different fills in as an optional framework that can adequately lessen the vibrations. This mix upgrades the customary framework that is right now introduced in vehicles without bargaining on solace and street hold.

Authors: Owais Lubna , T. Kiss Judit
Published: December 2020

Jordan is now facing real challenges to satisfy the current population water needs due to limited resources. Moreover, unfortunately, as a result of the increased demand for water in developing countries, water resources become scarce, thus, the sustainable management of water resources is very important everywhere and especially in these areas. The Ministry of Water and Irrigation in Jordan is aiming to improve both its quality of service and financial sustainability, therefore, it started to apply the performance measurement system developed by the International Water Association (IWA) to monitor its performance towards achieving these goals. In this article, a model connecting a financial sustainability indicator (operating cost coverage ratio) with other performance indicators applied by the ministry is developed. To assess the performance indicators and to build the model secondary data are collected from the targeted company, the data are analyzed using SPSS and Excel computer programs. Non-revenue water (NRW), speed of repair of bursts, and training per employee are found to be the indicators that have a major impact on Miyahuna’s financial sustainability, the NRW is found to have a negative relationship with the financial sustainability, whereas the other two indicators have a positive relationship. As a conclusion, reducing the NRW and increasing both the speed of repair and training per employee are recommended, by applying some methods that continuously diagnose problems in the water systems and defining clear and strict policies to control the water theft. Furthermore, using Active Leakage Control (ALC) methods, providing the needed equipment, tools and resources, and adopting new methods for training.

Tanulmányunkban arra vállalkozunk, hogy feltárjuk a diplomás (abszolutóriumot szerzett) pályakezdők társadalmi hátterét képzési területek szerint. Ennek során nagy hangsúlyt fektetünk a szülők iskolai végzettségére és a család anyagi helyzetére vonatkozóan, hiszen e tényezők szignifikáns hatást gyakorolhatnak a fiatalok tanulási lehetőségére, attitűdjére, valamint szakmai pályafutására. Kutatásunk elméleti részében fontosnak tartjuk ismertetni a hazai és nemzetközi szerzők szocio-ökonómiai helyzettel kapcsolatos tapasztalatait. Ezt követően a Diplomás Pályakövetési Rendszer (DPR) 2015-ös adatbázisa kiváló lehetőséget nyújtott számunkra, hogy a 34 felsőoktatási intézmény által gyűjtött komplex adatokat tanulmányozhassuk. Elemzésünk során rávilágítottunk a különböző tudományterületek végzettjeinek eltérő szocio-ökonómiai hátterére. Kutatási eredményeink alapján arra a következtetésre jutottunk, hogy a gazdagabb családokból származó fiatalok előnyösebb helyzetben vannak a munkaerőpiacon, magasabb jövedelemre tesznek szert, szemben az alacsonyabb társadalmi státuszú szülők gyerekeivel.
Nominate of significant features for unknown internet traffic applications filtering based on a neural network algorithm
Authors:   Faculty of Computer Science and Information Technology, Omdurman Islamic University, Khartoum, Sudan, et al. Mohamed
Published: December 2020

The evolution of the internet into a large, complex service-based network has posed tremendous challenges for network monitoring and control in terms of how to collect massive volumes of data, in addition to the accurate classification of new emerging applications, such as peer-to-peer networks, streaming content and online games. In this work, machine learning algorithms are used for the classification of traffic into their corresponding applications. Furthermore, this research uses our customized training data set collected from the three institutions' campuses. The effect on the size of the training data set has been considered before examining the accuracy of various classification algorithms and selecting the best from a large amount of data traffic in the network, which has led to delays in performance; therefore, to solve this problem we suggested a distinct approach using multiple neural networks with the feature selection in order to predict and identify known and unknown applications. By applying the proposed method, we get excellent accuracy in the classification of data traffic in the network of up to 99.11%, which leads to improved data traffic in the network and avoids delays.

Published: December 2020

There is currently no effective treatment for spinal cord injury leaving around 90% of patients with permanent disabilities. Stem cell therapies are showing promise in preclinical studies of central nervous system injury and there is increasing evidence suggesting the improvements in functional recovery are mediated by paracrine actions. In this systematic review and meta-analysis, we aimed to determine the overall efficacy of stem cell secretome therapies in promoting recovery in preclinical models of spinal cord injury. We searched PubMed and Embase to identify relevant studies. A random effects meta-analysis was conducted using the restricted maximum likelihood estimator. We assessed risk of bias using a modified CAMARADES checklist. Publication bias was then assessed using funnel plots and trim-and-fill analysis. We identified 26 studies that met our inclusion criteria. Overall, stem cell secretome therapies conferred improvement in locomotor score (SMD: 2.30, 95% CI: 1.68-2.91), reduction in lesion size (SMD: 3.27, 95% CI: 2.06-4.48) and increased axonal profiles in the lesion (SMD: 2.36, 95% CI: 1.02-3.71). We found there was significant asymmetry in the funnel plots for all three outcome measures, suggesting publication bias. Trim-and-fill analysis estimated 19 and 3 unpublished studies in the locomotor score and axonal profiles datasets respectively. The median score on the modified CAMARADES checklist was 4 (IQR 4-5). Reporting of power calculations and allocation concealment was absent. The stem cell secretome is showing great potential as a therapy for spinal cord injury. As the vast majority of studies began treatment acutely and favoured reduction in lesion size, we argue neuroprotection is likely the key mechanism of action. Future studies should focus on exploring the contribution of other mechanisms, the mediators involved and effect of treatment at a chronic stage of injury.
Occurrence of indigenous arbuscular mycorrhizal fungi associated with the rhizosphere of the naidí palm in Colombia
Authors: Montenegro Gómez Sandra Patricia , Barrera Berdugo Silvia Eugenia , Mosquera Mena Ramón Antonio
Published: December 2020

In the Colombian Pacific region, the naidí palm, Euterpe oleracea Mart. (Arecaceae) produces high-value fruit due to its high nutritional quality, representing an economic benefit to the families of the region. In this study, we evaluated the occurrence of arbuscular mycorrhizal fungi (AMF) in the rhizospheric soil of E. oleracea in Bajo Calima, Buenaventura. This is the first report of AMF of E. oleracea in Colombia. Surface soil samples (0-10 cm) were collected in two areas (L1 - under the influence of rice cropping and L2 - tropical rainforest). The chemical properties of the soil, the number of spores, and the mycorrhizal colonization in the root were established. We observed low mycorrhizal colonization (10 % in L1 and 4 % in L2), negatively correlated to the content of available phosphorus in the soil. However, significant differences between areas (p = 0.009) were recorded. Globose, subglobose, and ovoid spores were observed (660 and 791 spores/100 g soil in L1 and L2, respectively). Spores are represented in several morphotypes that can be classified as Claroideoglomeraceae, Glomeraceae, Diversisporaceae, Paraglomeraceae, and Ambisporaceae. High available P content (13.1 mg/kg in L1 and 20.5 mg/kg in L2), among other edaphic factors associated, could explain the low mycorrhizal colonization observed, especially when there are not enough studies linking ecological factors with AMF dynamics in tropical rainforests. On the other hand, spore abundances reported in the rhizospheric soil of E. oleracea suggest a high potential to explore indigenous AMF activity in the Colombian Pacific region to achieve sustainable production practices in this palm.

Published: December 2020

BACKGROUND

Self-reported mood is a valuable clinical data source regarding disease state and course in patients with mood disorders. However, validated, quick, and scalable digital self-report measures that can also detect relapse are still not available for clinical care.

OBJECTIVE

In this study, we aim to validate the newly developed ASERT (Aktibipo Self-rating) questionnaire—a 10-item, mobile app–based, self-report mood questionnaire consisting of 4 depression, 4 mania, and 2 nonspecific symptom items, each with 5 possible answers. The validation data set is a subset of the ongoing observational longitudinal AKTIBIPO400 study for the long-term monitoring of mood and activity (via actigraphy) in patients with bipolar disorder (BD). Patients with confirmed BD are included and monitored with weekly ASERT questionnaires and monthly clinical scales (Montgomery-Åsberg Depression Rating Scale [MADRS] and Young Mania Rating Scale [YMRS]).

METHODS

The content validity of the ASERT questionnaire was assessed using principal component analysis, and the Cronbach α was used to assess the internal consistency of each factor. The convergent validity of the depressive or manic items of the ASERT questionnaire with the MADRS and YMRS, respectively, was assessed using a linear mixed-effects model and linear correlation analyses. In addition, we investigated the capability of the ASERT questionnaire to distinguish relapse (YMRS≥15 and MADRS≥15) from a nonrelapse (interepisode) state (YMRS<15 and MADRS<15) using a logistic mixed-effects model.

RESULTS

A total of 99 patients with BD were included in this study (follow-up: mean 754 days, SD 266) and completed an average of 78.1% (SD 18.3%) of the requested ASERT assessments (completion time for the 10 ASERT questions: median 24.0 seconds) across all patients in this study. The ASERT depression items were highly associated with MADRS total scores (P<.001; bootstrap). Similarly, ASERT mania items were highly associated with YMRS total scores (P<.001; bootstrap). Furthermore, the logistic mixed-effects regression model for scale-based relapse detection showed high detection accuracy in a repeated holdout validation for both depression (accuracy=85%; sensitivity=69.9%; specificity=88.4%; area under the receiver operating characteristic curve=0.880) and mania (accuracy=87.5%; sensitivity=64.9%; specificity=89.9%; area under the receiver operating characteristic curve=0.844).

CONCLUSIONS

The ASERT questionnaire is a quick and acceptable mood monitoring tool that is administered via a smartphone app. The questionnaire has a good capability to detect the worsening of clinical symptoms in a long-term monitoring scenario.
Measuring the Interactions Between Health Demand, Informatics Supply, and Technological Applications in Digital Medical Innovation for China: Content Mapping and Analysis (Preprint)
Authors: Du Jian , Chen Ting , Zhang Luxia
Published: December 2020

BACKGROUND

There were 2 major incentives introduced by the Chinese government to promote medical informatics in 2009 and 2016. As new drugs are the major source of medical innovation, informatics-related concepts and techniques are a major source of digital medical innovation. However, it is unclear whether the research efforts of medical informatics in China have met the health needs, such as disease management and population health.

OBJECTIVE

We proposed an approach to mapping the interplay between different knowledge entities by using the tree structure of Medical Subject Headings (MeSH) to gain insights into the interactions between informatics supply, health demand, and technological applications in digital medical innovation in China.

METHODS

All terms under the MeSH tree parent node “Diseases [C]” or node “Health [N01.400]” or “Public Health [N06.850]” were labelled as H. All terms under the node “Information Science [L]” were labelled as I, and all terms under node “Analytical, Diagnostic and Therapeutic Techniques, and Equipment [E]” were labelled as T. The H-I-T interactions can be measured by using their co-occurrences in a given publication.

RESULTS

The H-I-T interactions in China are showing significant growth and a more concentrated interplay were observed. Computing methodologies, informatics, and communications media (such as social media and the internet) constitute the majority of I-related concepts and techniques used for resolving the health promotion and diseases management problems in China. Generally there is a positive correlation between the burden and informatics research efforts for diseases in China. We think it is not contradictory that informatics research should be focused on the greatest burden of diseases or where it can have the most impact. Artificial intelligence is a competing field of medical informatics research in China, with a notable focus on diagnostic deep learning algorithms for medical imaging.

CONCLUSIONS

It is suggested that technological transfers, namely the functionality to be realized by medical/health informatics (eg, diagnosis, therapeutics, surgical procedures, laboratory testing techniques, and equipment and supplies) should be strengthened. Research on natural language processing and electronic health records should also be strengthened to improve the real-world applications of health information technologies and big data in the future.

Published: December 2020

This study was conducted to determine the prevalence of ectoparasite infestation among stray cats around Surabaya traditional markets. A total of 305 stray cats were collected around 17 traditional markets in Surabaya City and were examined for the presence of fleas with a fine-toothed flea comb. Surveys were conducted during May-June 2019. 228 of 305 stray cats (74.75%) were infested with one species of ectoparasite. The average number of C. felis in every cat was 2.54, while the number of F. subrostratus in every cat was 0.33. Additional data about the gender, pregnancy/maternity, and bodyweight of every cat were recorded. The result of chi-square test shows that there is a significant difference between gender, pregnancy status, and bodyweight by the occurrence of ectoparasites (p=0.008; p=0.00; p=0.00). A total of 878 ectoparasites consisting of flea and lices, namely Ctenocephalides felis (88.27%) as the dominant ectoparasite, followed by Felicola subrostratus (11.73%). The highest infection rate (prevalence) of ectoparasite was found in Pucang Market (16.81%), while the lowest prevalence was found in Mulyorejo Market (0.8%). Coinfection was observed in only a few cats (1.63%). Multiple Regression showed that pregnancy is the most influential factor in the occurrence of fleas (p=0.000). These results should be taken into account among health workers to prevent a possible outbreak of zoonotic diseases caused by fleas.
Ulva lactuca Linnaeus Potentially Promotes Reproductive Indices and Depressive-like Behavior of Hypertriglyceridemia Male Wistar Rats (Rattus norvegicus Berkenhout, 1769)

Published: December 2020

Excessive consumption of fatty foods can lead to hyperlipidemia, which is often coupled with hypertriglyceridemia (HTG), a condition where blood plasma triglyceride (TG) levels elevated beyond normal levels. This condition may disturb physiological functions of the body, such as reproductive functions, and other physiological imbalances leading to chronic stress and depression. Ulva lactuca is a potential natural treatment for HTG, as it contains various nutrients to aid physiological functions. This seaweed also has high levels of Cd, which can increase depression. Therefore, research on the potential benefits of U. lactuca should be followed by an investigation of its health risks. This research aimed to examine the effects of HTG and treatment with U. lactuca on reproduction and depressive-like behavior of male Wistar rats (Rattus norvegicus Berkenhout, 1769). The data collected in this research include body weight, serum TG concentration, gonadosomatic index (GSI), serum testosterone concentration using competitive ELISA, and depressive-like behaviors assessed using the Forced Swim Test (FST) and Open Field Test (OFT). Data were analyzed using One-Way ANOVA followed by DMRT, independent- and paired-samples t-test, and Kruskal-Wallis H test with a significance value of α=0.05. Body weight, serum TG and testosterone concentration, GSI, and depressive-like behaviors were increased by the HTG condition. Ulva lactuca at the1500 mg/kg BW/day did not significantly affect body weight, testosterone concentration, and depressive-like behaviors of HTG rats. Meanwhile, this treatment significantly increased the GSI and depressive-like behaviors of healthy rats. These results suggest that Ulva lactuca treatment not only enhances gonad growth and development but also increases depressive-like behaviors.

Published: December 2020

El objetivo de este trabajo es indagar si el tipo de arreglo residencial familiar influye en la calidad de vida de sus integrantes, aspecto que se ve reflejado en desigualdades en el bienestar socioeco-nómico, desigualdades de género en el ejercicio del poder y desigualdades según el grado de ur-banización del lugar de residencia. La fuente de datos empleada es la Encuesta Intercensal 2015. La clasificación de los arreglos está basada en Laslett y Wall (1972) que permite distinguir entre arreglos simples y múltiples. Para el análisis, se construyó un índice de bienestar y se aplicaron modelos de regresión logística binarios. Los principales resultados son los siguientes. El tipo de arreglo residencial más ventajoso en términos del bienestar socioeconómico de sus miembros es el nuclear, mientras que, en el caso del arreglo monoparental, depende de su composición. En ge-neral, la figura de “jefe” del arreglo residencial asignada por sus integrantes, atribuye con mucha frecuencia a los hombres esta característica; esta situación varía según el tipo de arreglo. En la Ciudad de México, contexto altamente urbanizado, los arreglos nucleares son menos frecuentes, el clima educativo es más alto y la jefatura femenina más usual.

Recentemente os militantes radicalizaram, em protesto contra a Proposta de Emenda à Constituição nº 241, promulgada pela Emenda Constitucional nº 95, que limita despesas e compromete investimentos em educação. A experiência resultou em mais sentimento de empatia, solidariedade e habilidade para articular os coletivos em favor de conquistas políticas entre os sujeitos da ação social.

Authors: Bernardi Luci dos Santos , Delizoicov Nadir Castilhos , Cecco Bruna Larissa
Published: December 2020

O presente trabalho tem como foco a Formação do Professor Indígena imbricada com as demandas contemporâneas da Educação Escolar Indígena, cuja presença nas comunidades constitui uma possibilidade para o diálogo acerca da interculturalidade, saberes diversos e práticas educativas. Nosso objetivo é tensionar a sua concretização a partir do protagonismo dos professores indígenas, colocando em pauta os processos formativos desses profissionais, referenciando os cursos de formação específicos e as pesquisas desenvolvidas nas universidades do estado de Santa Catarina, Brasil. Se hoje há o desejo e o amparo legal para construir uma escola indígena diferenciada, faz-se necessário criar mecanismos eficientes para que o Estado e a sociedade tornem isso possível.
Da educação ambiental à educação para a sustentabilidade: uma proposta para a América Latina baseada na metodologia Service-Learning
Authors: Martínez-Agut María del Pilar
Published: December 2020

A educação ambiental está muito consolidada hoje após uma jornada de várias décadas. Mas os fatores que afetam a sustentabilidade (meio ambiente, economia e social) significam que a educação ambiental deve apresentar uma inter-relação com outros fatores, e os Objetivos de Desenvolvimento Sustentável apresentam uma estrutura essencial na educação atual. Portanto, a continuidade da educação ambiental é proposta em sua área específica de intervenção, mas com uma abertura para os aspectos incluídos nos ODS, pessoas, planeta, prosperidade, pactos e paz. Para isso, a metodologia de Aprendizagem de Serviços é apresentada como válida para o desenvolvimento da educação para a sustentabilidade e os ODS.

Authors: Makibara Ribeiro Thereza , Duarte Galvani Márcia
Published: December 2020

Este estudo teve como objetivo investigar se os eixos estruturantes do PNAIC auxiliam na prática pedagógica do professor frente à alfabetização de alunos com DI. Trata-se de um estudo de campo realizado mediante uma abordagem qualitativa com delineamento descritivo. Foram participantes deste estudo três professoras da classe comum dos anos iniciais do Ensino Fundamental (1º ao 3º ano) e duas professoras da Educação Especial voltadas ao atendimento do aluno com DI. Para alcançar os objetivos propostos, foram realizadas observações sistemáticas em sala de aula descritas em um roteiro de observação e no diário de campo. Além disso, os participantes responderam um roteiro de entrevista semiestruturado. Para a análise dos dados, foram realizadas análises de conteúdo por categoria temática com os dados obtidos nas entrevistas. Tal estudo possibilitou reflexões sobre os eixos estruturantes do PNAIC na prática pedagógica dos professores que atuam com alunos com deficiência intelectual em suas classes e as contribuições deste no processo de alfabetização e letramento. Os dados revelam uma necessidade de reorganização na forma como são propostos os eixos estruturantes do programa para que todos os professores da rede regular de ensino, incluindo professores da Educação Especial, sejam capazes de desenvolver estratégias pedagógicas que possam contribuir para a efetivação do processo de alfabetização e letramento do aluno com deficiência intelectual.

Authors: De Sousa Nádia Jane
Published: December 2020

Este estudo pretende discutir o processo de midiatização da infância a partir de um estudo exploratório com crianças de quatro e cinco anos em instituições públicas brasileiras. O trabalho objetiva identificar elementos desse processo que estão presentes entre crianças pré-escolares. Pretende também verificar, a partir das interações em seus ambientes formais de educação, de que modo os seus cotidianos se conjugam com os meios de comunicação e como incorporam conteúdos midiáticos nas formas de ser/estar criança. A partir de atividades diversas com a participação ativa dos grupos, foi possível identificar a presença de elementos de midiatização em seus modos de brincar, nos brinquedos que possuem e nos que desejam adquirir, na relação que estabelecem com as mídias eletrônicas e digitais, especialmente o YouTube, com destaque para os YouTubers.

AS CRIANÇAS E A ESCOLA: concepções, sentidos e funções
Authors: Maia Denise da Silva , Rozek Marlene
Published: December 2020

Amparada na Sociologia da Infância, a pesquisa buscou compreender como a escola é percebida e significada por crianças do 1º ano do Ensino Fundamental de duas escolas de Porto Alegre (RS), uma pública e uma privada. Foram realizados grupos focais, desenhos e escritas para apreender as concepções das crianças, bem como os sentidos e as funções atribuídos à escola. As narrativas verbais foram submetidas à Análise Textual Discursiva e os desenhos foram analisados a partir de um amálgama de autores. Na concepção das crianças, a escola é um lugar, mas transcende a mera dimensão espacial, uma vez que está permeada por sensações, afetos e memórias. É o lugar de aprender, onde as práticas são coletivas e realiza-se um tipo particular de trabalho, o trabalho escolar, estando associada a determinados símbolos. A escola é percebida como um espaço das crianças, que é importante, obrigatório e positivo frequentar; serve para aprender, em primeiro lugar, e para brincar, divertir-se e fazer amigos.

Authors: Firmino Magalhães Barbosa Raquel , Alves Costa Zandominegue Bethânia , Da Silva Mello André
Published: December 2020

Analisa práticas brincantes e narrativas infantis provenientes de estudos nos espaçostempos da Educação Física com a Educação Infantil. Para tanto, realiza uma revisão sistemática no Catálogo de Teses e Dissertação da Capes, com metassíntese qualitativa para análise dos dados, em articulação aos pressupostos teóricos da Sociologia da Infância. Os resultados encontrados foram agrupados nas seguintes categorias: singularidades da infância, reconhecimento das produções culturais infantis e diálogo entre culturas infantis e culturas escolares. Evidenciou-se que é possível identificar práticas brincantes e narrativas infantis com a utilização de métodos de pesquisas que considerem as crianças como sujeitos ativos e as suas múltiplas linguagens. Esse reconhecimento advém das relações estabelecidas com elas nos espaços formativos, na institucionalização de suas experiências nos currículos e na aproximação com suas singularidades comunicativas e de produção de conhecimentos.

Saberes y prácticas con TIC: ¿instrumentalismo o complejidad?
Authors: Monjelat Natalia , Peralta Nadia , San Martín Patricia
Published: December 2020

Este estudio tiene como objetivo identificar, caracterizar y describir saberes y prácticas con TIC de maestros de educación primaria que inician un trayecto de formación en Didáctica de las ciencias de la computación (n=80). Mediante un cuestionario ad hoc, se caracterizó la muestra, se construyeron categorías emergentes y se realizó un análisis multivariado de correspondencias múltiples (factorial y de clasificación), que se complementó con técnicas del análisis de discurso. Los resultados revelaron diversos saberes y prácticas con TIC, siendo la capacitación, la experiencia docente y el uso de TIC los ejes clave en la constitución de estas diferencias. Se identificaron prácticas digitales mayormente instrumentales y saberes previos centrados en habilidades genéricas. Los trayectos formativos sistematizados y apoyados por políticas públicas aparecen como caminos posibles para desarrollar la comprensión crítica desde una perspectiva compleja, alejada de estándares y lineamientos que, a su vez, suponen las mismas habilidades en todos los contextos.
