Some Persistent Mysteries of Malory’s Texts and Sources
Authors: Norris Ralph
Published: September 2021

Despite a century of dedicated scholarship, some textual problems remain in Malory’s Morte Darthur that have never been satisfactorily explained. Although these mysteries tend to be rather small, seeking the most probable rational solution to them increases our understanding of Malory as an author, as well as the Morte Darthur as a medieval masterpiece, in addition to the connection between the two. This paper offers explanations of the word amyvestial, of unknown etymology, Sir Gareth’s ungrammatical sobriquet Beaumains and other small but baffling mysteries of Malory’s text.
Photocatalytic activity of biogenic zinc oxide nanoparticles: In vitro antimicrobial, biocompatibility, and molecular docking studies
Authors: Alam Mahboob
Published: September 2021

The biogenic synthesis of zinc oxide nanoparticles (ZnO NPs) with pinecone extract (PCE) as a reducing agent and antibacterial agent was explored. The current study aims to investigate the biosynthesis of ZnO NPs and their effect on photocatalytic dye degradation and antimicrobial properties. The physical, chemical, and morphological properties of biogenic ZnO NPs synthesized using PCE were investigated using advanced spectroscopy techniques such as Fourier transform infrared spectroscopy (FTIR), UV-visible spectroscopy, transmission electron microscopy (TEM) analysis, selected area electron diffraction (SAED), and X-ray diffraction (XRD) techniques. The photocatalytic degradation of methylene blue was measured spectrophotometrically using biogenic ZnO NPs as nanocatalysts, and decolonization of solution indicates dye degradation gradually as exposure duration increases. The antimicrobial properties of ZnONPs against the tested pathogenic strains were demonstrated using the disc diffusion method. The antimicrobial efficacy of ZnONPs was further explained using molecular docking analysis. Confirmation of the lowest binding energy was used to predict receptor binding site with NPs in order to understand the mechanistic approach. ZnONPs are likely to interact with pathogens via mechanical enfolding, which could be one of the major toxicity actions of ZnONPs against strains. Furthermore, the nontoxicity and biocompatibility of ZnO NPs were studied, revealing impressive hemocompatibility with red blood cells (RBCs) and no significant toxicity to Brine shrimps at lower ZnONP concentrations.

Published: September 2021

High-entropy alloys (HEAs) have become a research focus because of their easy access to nanostructures and the characteristics of high strength, hardness, wear resistance, and oxidation resistance, and have been applied in aerospace lightweight materials, ultrahigh temperature materials, high-performance materials, and biomimetic materials. At present, the study of HEAs mainly focuses on the microstructure and mechanical properties. HEAs of Mo, Ti, V, Nb, Hf, Ta, Cr, and W series have high strength, while HEAs of Fe, Co, Ni, Cr, Cu, and Mn series have good toughness. However, the emergence of medium-entropy alloys, metastable HEAs, dual-phase HEAs, and multiphase HEAs increased the complexity of the HEA system, and the phase transition mechanism and strengthening and toughening mechanisms were not fully established. In this article, the preparation, phase formation, phase transformation as well as strengthening and toughening mechanisms of the HEAs are reviewed. The inductive effects of alloying elements, temperature, magnetism, and pressure on the phase transformation were systematically analyzed. The strengthening mechanisms of HEAs are discussed, which provides a reference for the design and performance optimization of HEAs.

Published: September 2021

Compounds that trigger breast cancer onset and establishment are of great interest in biological research. Endocrine disruptors are relevant because they initiate carcinogenesis by changing endocrine pathways. Bisphenol A (BPA), as a ubiquitous xenoestrogen, is largely associated with dysfunctions in the female reproductive system and associated organs. This study proposes an investigation of the mammary gland (MG) in aged Mongolian gerbil (Meriones unguiculatus) mothers after their exposure to BPA in two windows of morphophysiological plasticity: pregnancy and lactation. A low dose (50 μg/kg) and a high dose (5000 μg/kg) of BPA were considered, and results showed few differences between them. As expected, we observed contrasts among control and BPA-exposed MG. The control groups presented a regressive phase with high apoptotic activity and elastic stroma. However, BPA damaged mammary tissue and provoked multifocal carcinoma development supported by an apparent epithelial-mesenchymal transition (EMT) and reactive stroma establishment. BPA remodeled stromal fibers deposition and enhanced the recruitment of tumor-associated cells, contributing to a tumoral microenvironment. Overexpression of TGF-β1 was induced by BPA in the epithelial compartment of exposed MG, and increased expression of metalloproteinases (MMP-2, MMP-3, MMP-9) was present in carcinoma cells. In conclusion, exposure of mothers to BPA during the gestational/lactational window of susceptibility leads to carcinogenic impacts with aging.

Published: September 2021

Approximately one-half of patients undergoing diagnostic coronary angiography for angina have no significant coronary atherosclerotic stenosis. This clinical condition has recently been described as ischaemia with non-obstructive coronary arteries (INOCA). Coronary functional abnormalities are central to the pathogenesis of INOCA, including epicardial coronary spasm and coronary microvascular dysfunction composed of a variable combination of increased vasoconstrictive reactivity and/or reduced vasodilator function. During the last decade – in INOCA patients in particular – evidence for the prognostic impact of coronary functional abnormalities has accumulated and various non-invasive and invasive diagnostic techniques have enabled the evaluation of coronary vasomotor function in a comprehensive manner. In this review, the authors briefly summarise the recent advances in the understanding of pathophysiology and diagnosis of epicardial coronary artery spasm and coronary microvascular dysfunction.

Published: September 2021

La evaluación y zonificación de la amenaza es una herramienta fundamental para la ordenación del territorio. Actualmente tiene importancia como principal producto para los Planes de Ordenamiento Territorial (POT) señalar las áreas con condición de amenaza que deberán supeditar su desarrollo a la realización de los estudios detallados de amenaza, y las áreas con condición de riesgo que requieren igualmente de estudios detallados para establecer las áreas de riesgo no mitigables y las medidas de mitigación necesarias. El aumento en la frecuencia y pérdidas asociadas a desastres por fenómenos de origen natural, refleja la forma inadecuada en la cual se ha incorporado la gestión del riesgo en los ejercicios de ordenación de los territorios en Colombia. La normatividad colombiana (El Decreto 1077/2015) estableció las especificaciones y escalas de los estudios técnicos para la incorporación de la gestión del riesgo en la planificación territorial, denominados Estudios Básicos de Amenaza y Estudios Detallados. En el presente trabajo se presenta y discute la definición de las áreas con condición de amenaza y áreas con condición de riesgo, como herramienta para la ordenación del territorio. Para esto se presenta como caso de estudio el municipio de Caldas, en el departamento de Antioquia. El procedimiento utilizado se convierte en una guía útil para diferentes municipios, ya que señala no solo la metodología utilizada, sino además los diferentes conflictos que se presentan en los procedimientos, y recomendaciones para un adecuado manejo.
Estudio de afectación del servicio ecosistémico de regulación hídrica por actividades de agricultura en la cuenca del río Gachaneca I, páramo Rabanal

Published: September 2021

Los páramos colombianos son ecosistemas estratégicos en cuanto al suministro de diferentes servicios ambientales, incluyendo servicios asociados al recurso hídrico. A pesar de las acciones encaminadas hacia la conservación de páramos, muchos de estos se encuentran intervenidos por diferentes actividades antrópicas. La cuenca del río Gachaneca I del páramo Rabanal no es la excepción a estas dinámicas y, aunque una parte de la cuenca está en buen estado de conservación, otra se caracteriza por la ocupación de cultivos transitorios que vulnera la prestación de servicios de provisión y de regulación hídrica. En este estudio se diseñó una metodología en donde se evaluó el efecto que genera el desarrollo de actividades agrícolas sobre los servicios hídricos. Entre los principales hallazgos se encontró que la oferta hídrica media disminuyó en un 8,8% bajo el escenario de presión por agricultura, llegando a ser equivalente a la oferta hídrica en los meses de estiaje de años hidrológicos secos. La variabilidad interanual del recurso hídrico incrementa en un 9,9% indicando una mayor irregularidad en la oferta temporal de escorrentía superficial y, como consecuencia, mayor irregularidad del servicio de provisión del agua. El desarrollo de actividades de riego disminuye en un 27,8% la capacidad de regulación de la cuenca que, por sus condiciones de suelo y coberturas vegetales, no dispone de una condición natural apropiada para regular la escorrentía superficial. De esta manera, es necesario profundizar en la investigación de este panorama para mitigar los efectos negativos sobre este tipo de ecosistemas.

Authors: Zafra-Otero Diego , Ríos-Reyes Carlos Alberto
Published: September 2021

The present study integrates geological, mineralogical and geochemical methods in the characterization of the caves: El Nitro and Las Alsacias, from Zapatoca (Colombia). With lithologies dating from the Lower Cretaceous, these cavities reveal a great variety of exokarst geoforms with different types of slips present on the surface, indicating changes in past atmospheric conditions. A great variety of speleothems (endokarstic geoforms) was also found, such as columns, stalactites, stalagmites, among others, which demonstrate a change in calcite saturation in the precipitated water. The morphology of the underground water bodies found showed variations in the dynamics of the karst aquifer (piezometric level and recharge), and it was evidenced that these cavities have structural control. The information obtained in the field (speleothematic catalogs, speleometry, maps, lithostratigraphy and structural data) were validated with atmospheric data and laboratory tests. This research provides new insights into geomorphology (epigeal and hypogeal), hydrogeology and mineralogy; serving as support for future work focused on paleoclimatic reconstruction, tectonic, paleosismic and climate change studies. These cavities represent scientific laboratories of great interest to the academy, since in them phenomena such as global warming and piezometric variations related to atmospheric phenomena can be evidenced.

This work developed prediction models for maximum dry unit weight (γd,max) and optimum moisture content (OMC) for compacted soils in Ceará, Brazil, ba M Winnie the Pooh sed on index and physical properties. The methodology included data from soils used in the construction of 15 dams in Ceará, with available information regarding laboratory tests of interest. Correlations were developed using non-linear regression, from 169 laboratory results (83 for training and 86 for validating the models), which presented a R2 of 0,763 for MoPesm (prediction model for γd,max) and 0,761 for MoTuo (model for OMC). A posteriori, the same physical indexes used to train and validate MoPesm and MoTuo were used as inputs of other prediction models available in the literature, whose outputs differed considerably from laboratory results for the evaluated soils. MoPesm and MoTuo were able to satisfactorily predict compaction parameters, with outputs close to those obtained in the laboratory for tested soil samples. Their performance justifies their use for predicting compaction parameters in geotechnical structures that use compacted soils when there are financial restraints, short timeframes, or unavailability of test equipment, particularly in early design stages and preliminary studies, before appropriate soil sampling and field investigation can be conducted, thus saving substantial time and financial resources.

Published: September 2021

In network management and monitoring systems, or Network Management Stations (NMS), the Simple Network monitoring Protocol (SNMP) is normally used, with which it is possible to obtain information on the behavior, the values of the variables, and the status of the network architecture. network. However, for large corporate networks, the protocol can present latency in data collection and processing, thus making real-time monitoring difficult. This article proposes a multi-agent system based on layers, with three types of agents. This includes the collector agent, which uses a Management Information Base (MIB) value to collect information from the network equipment, an input table of information from the network devices for the consolidator agent to process the collected data and leave it in a consumable format, and its subsequent representation by the application agent as a web service, in this case, as a heat map.

Effect of organic and chemical fertilizers on the growth and production of soybean (Glycine max) in dry land
Authors: Sandrakirana Ratih , Arifin Zainal
Published: September 2021

Soybean is known for its high protein content, which is the reason why it is widely used as one of the main food sources for humans and animals. In order to optimize soybean growth, farmers tend to add excessive dosage of chemical fertilizer to this crop. Furthermore, a continuous chemical fertilizer application without organic fertilizer addition may cause a rapid depletion of nutrients in the soil. This study aimed to evaluate the effectiveness of organic fertilizer treatment to reduce the amount of urea as chemical fertilizer needed in soybean cultivation. A complete randomized design was conducted using 21 treatments of organic and chemical fertilizer in triplicate with a 4x3 m plot size. Analysis of variance was carried out to compare the means of measurement data and Duncan multiple range test (DMRT 5%) was applied. The treatment 2,000 kg ha-1 compost + 50 kg ha-1 urea (O2K2A1) resulted the highest dry yield in soybean and had significant differences with urea-only treatment. A mixture of chemical and organic fertilizers had no significant result over the yield compared to the use of chemical fertilizer only. Compost application of 1,000-2,000 kg ha-1 with urea 50-100 kg ha-1 (O2K2A1 and O 2K1A2) showed an increase in seed yield of 35-38 % with a profit reaching 333-340 USD ha-1 compared to standard treatment using urea 50 kg ha -1 + SP-36 50 kg ha-1 + 50 KCl kg ha-1 (O0K0A1).

Die Kuh vom Eis bringen. Landwirtschaft als metaphorischer Herkunftsbereich für Phraseolexeme des Deutschen und Albanischen.
Authors: Sadikaj Sonila
Published: September 2021

The aim of this contrastive study is to examine the source domain “agriculture” as an image donor for a large number of phraseological units in German and Albanian and to address the question which agricultural terms belong to the phraseological inventory in both languages and which metaphorical target domains are linguistically structured by them. This language combination consists of two Indo-European languages whose peoples have not been in direct contact with each other in the course of history. Identifying differences and similarities in this regard would be of great interest – especially the latter, because phraseological universals could be discovered in the similarities between these not very closely related languages and peoples.

Stress-strain state of a borehole determined analytically using drilling-out as a technology of reducing differential settlement
Authors: Pronozin Yakov , Kajgorodov Mikhail , Gerber Aleksandr
Published: September 2021

The existing approaches for reducing the differential settlements of buildings and structures have their own advantages and disadvantages. Lowering of a building or part of it is one of the promising methods to reduce the differential settlements of shallow foundations resting upon weak silt-loam soils. The effect is achieved by drilling-out vertical boreholes in the immediate vicinity of the foundation from the minimal settlements. Method: Russian and foreign scientists have been involved in the development of calculation procedures for horizontal and inclined drilling-out of boreholes. It has been important to determine drilling parameters when using this technology and how soil characteristics and stress state of soils around the borehole influence the reduction of differential settlements. The paper discusses the influence of the strength characteristics of soils on the stress state of the soil massif around the borehole, as well as the influence of the borehole radius on the formed areas of limit state. The analytical solution is based on the well-known ratio used to determine the stress state around the borehole during pressure tests. Tangential and radial stresses are determined from this ratio; next, they are checked according to the condition of the strength law, and thus, the stress state around the borehole becomes evident. Result: The stress state of the soil around the boreholes has been calculated by the given method; it has made it possible to calculate the areas of soil destruction and determine the parameters of boreholes and their geometry depending on the purposes when regulating the settlements of slab foundations. It has been established that drilling behind the foundation contour in relation to drilling in the foundation contour makes it possible to increase the radius of the plastic deformation zone up to two times under the same soil conditions and well geometry.
Prevailing emotional components in adolescent girls with eating disorders
Authors: Bogateeva Lyubov
Published: September 2021

The article presents the results of a study on the predominant emotional components in adolescent girls with eating disorders, which manifested itself in the form of anorexia nervosa. In connection with the growing popularization of stereotypical body parameters and the relevance of healthy eating in modern life among adolescent girls, there is an increase in the trend towards various eating disorders. The main predominant groups subject to such deviations are precisely adolescent girls and adolescent girls. Identifying the initial emotional manifestations caused by anorexia nervosa is essential for planning preventive school programs. The research used such methods as observation, oral questioning (conversation) and "Cognitive-emotive test" Yu.M. Orlova, N.D. Tvorogova. The analysis of the data obtained made it possible to identify the predominant components of emotional disorders, namely the mechanisms of psychological defense, which are probably worth paying attention to psychologists for more competent work. The mechanisms of psychological defense turned out to be: aggression against oneself and protection from shame. The neglect of such a serious problem by school psychological services can only exacerbate the growth of these disorders. An approximate plan of preventive measures was developed, consisting of the main types of necessary work, namely: diagnostics, education, prevention, group sessions and individual assistance aimed at this category of adolescent girls and all participants in the general educational process. When developing this plan, recommendations were given for its implementation. Also, with individual work, it is worth paying special attention to the correction of emotional disorders.

ABSTRACT Objective: to analyze the understanding of mothers about sickle cell disease and/or trait of the family from a diagnosed child. Methods: this is a qualitative study, using a semi-structured interview with 23 mothers, at a sickle cell disease outpatient clinic of a public institution, from October to December 2017. Analysis was thematic. Results: all participants had sickle cell trait as well as the parents of their children. Twenty children were diagnosed with sickle cell disease by Heel Prick Test, and three, after hospitalization due to the disease. Most did not know how to report the presence of the trait or disease in relatives other than nuclear. Final considerations: diagnosis cannot be restricted to the result of neonatal screening, requiring that preventive information on sickle cell crises be reinforced. It is recommended to search for other affected relatives to learn about their genetic condition, reflecting on their reproductive decisions.

ABSTRACT: This research identified arbuscular mycorrhizal fungi (AMF) in rhizosphere soil of grapevines with Grapevine Death and Decline symptoms (GDD) or asymptomatic healthy (H) plants, and characterized the relationship of AMF communities with soil chemical attributes. The AMF spore number ranged from 287 to 432 spores 50 cm-3 in soil with GDD plants, and from 357 to 464 spores 50 cm-3 in H plants, with no differences among vineyards or between GDD and H plants within each vineyard. We detected 42 species and 17 genera, and most taxa belonged to Acaulosporaceae or Glomeraceae. Claroideoglomus etunicatum, Funneliformis mosseae, and Archaeospora trappei were the most frequent species in all vineyards. Soil chemical attributes were not determinant for the occurrence of most fungal species; although, Entrophospora infrequens, Diversispora sp1 and Diversispora sp2 were associated with a vineyard having high soil copper. Vineyards harbor highly diverse AMF communities, which are determined by location.

ABSTRACT: Temperament often depends on the animals’ reaction to people, social and environmental conditions. However, little is known about the influence of changes in the pasture environment on cattle temperament. Thus, this study was designed to evaluate if an animals’ temperament changes in response to being kept in a silvopastoral system. This study evaluated the effect of the tree components in a pasture environment on the temperament of any grazing cattle in integrated crop-livestock systems. A total of thirty-two Angus steers were allocated to either a livestock (L) or livestock-forest (LF) system and observed from December 2019 to February 2020. Each animal was evaluated for their reactivity score, flight speed, and number of vocalizations. The statistical model established that the animals were random effects and that the treatments and periods were fixed effects using the MIXED procedure, and the means were compared using LSMeans. The flight speed and number of vocalizations were similar in both production systems, while the reactivity score was lower for animals kept in the LF system when compared to those in the L system. This suggested that the LF system interferes positively with the animal’s temperament in relation to the L production system. However, additional research is needed to understand the influence of the production system on animal temperament.

Published: September 2021

Abstract Application of different fertilizers to check the efficiency of expression of Bt (Bacillus thuringiensis) gene in one of the leading commercialized crops (cotton) against Lepidopteran species is of great concern. The expression of Cry protein level can be controlled by the improvement of nutrients levels. Therefore, the myth of response of Cry toxin to different combinations of NP fertilizers was explored in three Bt cotton cultivars. Combinations include three levels of nitrogen and three levels of phosphorus fertilizers. Immunostrips and Cry gene(s) specific primer based PCR (Polymerase Chain Reaction) analysis were used for the presence of Bt gene that unveiled the presence of Cry1Ac gene only. Further, the ELISA (enzyme-linked immunosorbent assay) kit was used to quantify the expression of Cry1Ac protein. Under various NP fertilizers rates, the level of toxin protein exhibited highly significant differences. The highest toxin level mean was found to be 2.3740 and 2.1732 µg/g under the treatment of N150P75 kg ha-1 combination while the lowest toxin level mean was found to be 0.9158 and 0.7641 µg/g at the N50P25 kg ha-1 level at 80 and 120 DAS (Days After Sowing), respectively. It was concluded from the research that the usage of NP fertilizers has a positive relation with the expression of Cry1Ac toxin in Bt cotton. We recommend using the N150P50 kg ha-1 level as the most economical and practicable fertilizer instead of the standard dose N100P50 kg ha-1 to get the desired level of Cry1Ac level for long lasting plant resistance (<1.5). The revised dose of fertilizer may help farmers to avoid the cross-resistance development in contradiction of insect pests.

Abstract This article presents the results of the level of feeding and the health status of dairy cows in a commercial dairy farm on the content of the main components in milk (fat, protein, urea). The aim of the research was to study the milk productivity and composition of milk of cows, to analyze the level of feeding and the content of basic nutrients in the diet of the farm. The farm breeds purebred Holstein cattle with a high genetic potential for productivity. The milking herd was formed in 2009 on the basis of 600 heads of Holstein-Friesian heifers imported from Hungary, as well as 65 heads of Holsteinized heifers of Ukrainian selection from Ukraine in 2015. Today the livestock numbers about 1,500 head of cattle, of which there are about 900 breeders. On the territory of the farm there are: 3 cowsheds for keeping cows, an insemination room, a milking parlor with a parallel installation of the Delaval company, in which 48 cows are milked for one milking, the ABK, where the manager's office, livestock technician, accounting is located, and a mini-hotel with dining room and lounges. Dairy bases are equipped with auto-drinkers, ventilation, plumbing, electric lighting, manure removal mechanisms, and a milking installation. The object of the research was Holstein cows in the amount of 483 heads of Aina Dairy Farm LLP. The studies were carried out according to generally accepted zootechnical methods using modern equipment for conducting analyzes and interstate and state standards. The research results showed that the milk productivity of cows averaged 19.5 kg per day, the fat content 4.3%, the protein 3.9%, the number of somatic cells 230.5 thousand units / ml, urea 45.3 mg / 100 ml respectively. Analyzing the level of urea in milk can suggest a high crude protein content in the diet. The ration of feeding dairy cows on the farm is concentrate-silage-haylage and there is an excess of dry matter by 16.2%, crude protein by 9.8%, starch by 29.4%, respectively.
Fair and balance rate for benefits not scheduled in defined contribution plans
Authors: Nascimento Igor Ferreira do , Albuquerque Pedro H. M.
Published: September 2021

ABSTRACT The objective of this study is to propose a methodology that, using multiple decreases, in addition to classified by actuarial profile and source of social security costs, calculates actuarially fair and balanced rates for unscheduled collective costing benefits from Defined Contribution (DC) pension plans. There are no studies in Brazil about costing rates for benefits not scheduled in pension plans of the DC modality. Any institution that pays collective cost social security benefits must determine an actuarial rate that is not insufficient, generating a financial imbalance in the fund, nor excessive, compromising the participant’s income. This work is the first study on costing rates for collective costing benefits from pension plans with DC modalities. Actuarially fair rates are obtained considering multiple decreases and equalizing the present value of contributions and the present value of pension and disability benefits, classified by actuarial profile and source of social security cost. The specific balance rate is determined for each source of social security costs and is obtained considering the actuarially fair rates for each actuarial profile. The general balance rate is obtained by the marginal contribution of each specific balance rate. The proposed methodology was used to calculate the rates of unscheduled benefits with collective costing in DC modality plans. The proposed methodology estimated that the legal changes, resulting from Constitutional Amendment 103/2019, indirectly increased by more than 4% the general balance rate of the unscheduled benefits of the Supplementary Social Security Foundation of the Federal Public Servant of the Executive Branch of the Federal Government (FUNPRESP-Exe).
Autoridade, Violência e Educação
Authors: Trevisan Amarildo Luiz
Published: September 2021

Resumo O artigo procura enfocar a relação entre violência e a crise de autoridade no contexto educativo, tendo em vista o ambiente saturado da biopolítica. Procura interpretar a obra da fase final da vida de Sigmund Freud, O homem Moisés e a religião monoteísta como um testemunho contra-hegemônico da biopolítica. A partir de algumas teses defendidas na obra, especialmente a do lugar vago da imagem do pai, estabelece relações com o papel do docente diante do cenário de violência e falta de reconhecimento da sua atuação. Conclui que é necessário desconstruir o panorama que motivou a eclosão da violência original, cabendo, agora, reconstruí-lo na perspectiva hermenêutica. Bem como indica a necessidade de repensar a biopolítica na vida do professor, sempre desafiada a tomar partido por uma autoridade repressiva ou moral.
De volta ao brejo: a ausência do sublime em Dewey e o sublime na educação
Authors: Cavallari Filho Roberto
Published: September 2021

Resumo Neste artigo analiso a ausência do sublime em Dewey e o sublime na educação condensados na pergunta: o que significa para a formação humana afirmar que Dewey ignorou o sublime? Inicio o raciocínio apresentando a ausência do sublime nos escritos do filósofo. Posteriormente, apresento o sublime kantiano e seu impacto nos projetos modernos de emancipação, particularmente o projeto educacional da Bildung americana pautado na naturalização do idealismo objetivo hegeliano. Por fim, trago o sublime kantiano pensado na educação e na política por Lyotard para debater a formação humana e a crise da democracia hoje. O que está em jogo é a disputa entre emoções sem razão na busca de sentido político e educacional no espaço público amplificado pelas mídias sociais: fanatismo e ignorância. Argumento que é por meio da humildade da ignorância que podemos trazer à existência um propósito, a formação humana como uma ética de vida contra o fanatismo no presente.
El objeto de estudio de la profesión docente como reto epistemológico
Authors: Castañeda-Díaz María Teresa , Jarpa-Arriagada Carmen Gloria
Published: September 2021

Resumo Este artículo analiza el objeto de estudio de la profesión docente a partir de un ensayo bibliográfico. Afirmamos que el objeto es el conocimiento pedagógico y los mecanismos de distribución y adquisición de este saber en situaciones de enseñanza (Martín, 2006). Por tanto, es un objeto construido, definido y delimitado teórica y epistemológicamente al pensar la disciplina desde la profesión, los modelos formativos y los conocimientos profesionales que genera (Gadotti, 2015; Houssaye, 2014). Se realizó una revisión documental de 55 fuentes (de 1970 a 2015). Los hallazgos muestran que la literatura coincide en la importancia del conocimiento pedagógico como singularidad de la profesión. Asimismo, desde una visión posmoderna, la educación emerge como ciencia social en que el conocimiento se construye desde la praxis educativa en tanto práctica social contextualizada, situada histórica y culturalmente. La formación inicial docente debe enfatizar la construcción del saber profesional y su consecuente comunidad discursiva.

Resumo Objetivo Avaliar a frequência de Internação Hospitalar (IH) nos últimos doze meses em pessoas idosas atendidos na Atenção Primária à Saúde (APS) e seus fatores associados por meio de uma Avaliação Geriátrica Ampla (AGA). Métodos Estudo transversal, com amostra aleatória de 400 pessoas idosas atendidas em uma Unidade Básica de Saúde (UBS). A avaliação da frequência de IH por pelo menos 24 horas foi autorreferida (sim; não). Utilizou-se questionário sociodemográfico e de saúde, instrumentos para avaliar as atividades básicas e instrumentais da vida diária, status cognitivo, sintomas depressivos, queda e medo de cair. A regressão logística múltipla foi utilizada para investigar os fatores associados à IH. Resultados A média de idade foi de 75,23 (±8,53), 63,2% dos participantes eram do sexo feminino, 62,6% relataram um estado de saúde ruim/razoável e 38% relataram hospitalização nos últimos doze meses. Idade mais avançada, com pior percepção de saúde, doenças crônicas, uso diário de medicamentos, dependentes para as atividades básicas e instrumentais da vida diária, comprometimento do status cognitivo e queda no ano anterior demonstraram associação com a hospitalização. Saber ler e escrever foi associado com menor risco de hospitalização. Conclusão A frequência de IH de pessoas idosas atendidas em UBS foi alta e foi associada a fatores modificáveis e não modificáveis, indicando que a abordagem multidimensional é uma ferramenta importante no cuidado da pessoa idosa na atenção primária à saúde.
Saúde mental de acadêmicos de medicina: estudo longitudinal
Authors: Barbosa-Medeiros Mirna Rossi , Caldeira Antonio Prates
Published: September 2021

Resumo: Introdução: Poucos estudos avaliam de forma longitudinal a saúde mental e qualidade de vida de estudantes de medicina. Objetivo: Este estudo teve o objetivo de comparar os escores dos sintomas de transtornos psiquiátricos em acadêmicos de medicina ao longo de três anos da graduação, discutindo o contexto da saúde mental dos estudantes longitudinalmente durante o processo de formação. Método: Trata-se de um estudo longitudinal iniciado em 2015, com estudantes que estavam frequentando o 1º e o 7º períodos de graduação de três escolas médicas do norte de Minas Gerais. As mesmas turmas também foram abordadas nos anos seguintes, quando estavam no 3º e 9º, e no 5º e 11º períodos. Foram avaliados os sintomas depressivos, nível de sonolência diurna, nível de saúde geral, dimensões da Síndrome de Burnout, e qualidade de vida. Utilizou-se o teste não-paramétrico de Kruskal Wallis para comparar os três anos da graduação. Resultados: Dos 248 acadêmicos matriculados nos períodos selecionados, participaram 162 em 2015, 209 em 2016 e 221 em 2017. Para as turmas iniciantes, os escores do Questionário de Saúde Geral, que indica a presença de Transtornos Mentais Comuns, aumentaram entre 2015 e 2017. No mesmo período, houve aumento dos escores da dimensão descrença e redução significativa nos escores da dimensão eficácia profissional, do Maslach Burnout Inventory, denotando piora na saúde mental para esse grupo. Entre as turmas avaliadas a partir do meio do curso, observa-se aumento significativo nos escores do Questionário de Saúde Geral e na dimensão exaustão emocional do Maslach Burnout Inventory. A sonolência diurna excessiva apresentou oscilações durante os períodos. Conclusões: Os resultados refletem um agravamento na saúde mental destes estudantes ao longo do curso, especialmente entre o ano de 2015 e 2017, em relação a Transtornos Mentais Comuns e esgotamento profissional. Este resultado chama a atenção para a necessidade de se adotar estratégias que levem o estudante a lidar com os fatores estressantes inerentes ao curso, como o incentivo ao esporte, suporte psicológico, e a reorganização da estrutura curricular do curso, com períodos livres destinados a lazer.

Abstract: Introduction: The experience report describes the protocol used in one of the activities carried out during the initiative aimed at the search for health impact solutions through disruptive innovation - “IDEA2 Global, Guidance and transforming connections for innovators in medical technology”, in May 2019, at the Institute of Medical Engineering and Science, Massachusetts Institute of Technology (IMES MIT). Experience report: The Pre-Texts methodology was chosen to stimulate creativity and instill the curiosity inherent in the search for solutions to complex problems, through the reading of a challenging text and related activities in a workshop format. Bringing together professionals from various segments and nationalities, the two-hour and forty-five-minute period was the time spent on the workshop inspired by practices from some Latin American countries. Discussion: Through observation, it was observed that participants were engaged and fascinated by hands-on activities, amid the active reading of a text on neural connections in creative processes. The feedback from the evaluation on the workshop confirmed the facilitators’ impression. Conclusion: The Pre-Texts methodology is a strategy that can be applied in heterogeneous groups and can include skills such as creativity and collaboration. Thus, the use of this methodology should be encouraged in other similar situations.
