Authors: Couto Meg Caroline do , Xavier Raiane Teixeira , Hein Milene Moreno Ferro , Lisboa Helen Cristina Fávero
Published: April 2021

A presença de formigas em ambientes destinados à saúde pode gerar risco aos seres humanos, considerando que podem agir como veículo na disseminação de diversos micro-organismos potencialmente patogênicos. Nesse contexto, o estudo teve como objetivo isolar e identificar os micro-organismos transportados por formigas presentes em ambientes relacionados à saúde. Trata-se de uma pesquisa exploratória, de natureza aplicada, utilizando-se de uma abordagem quantitativa. A coleta das formigas foi realizada na enfermaria de uma Unidade de Pronto-Atendimento e Instituição de longa permanência de idosos localizadas num município da região sul de Mato Grosso. Os espécimes foram atraídos com iscas (goiabada, mel e açúcar) dispostas em placas de Petri estéreis e mantidas no local por um período de 3 horas. As formigas capturadas foram inseridas em meio de cultura líquido para o pré-cultivo dos micro-organismos. Em seguida uma alíquota da cultura foi semeada em ágar sangue e ágar Mueller Hinton visando a obtenção de cultura pura e a partir desta seguiu-se com a avaliação quanto a classificação morfo-tintorial (Gram). As colônias de cocos Gram positivo foram submetidas a testes para a diferenciação de Staphylococcus e Streptococcus e os bacilos Gram negativos avaliados quanto a fermentação de carboidratos. Foram isoladas 14 cepas de bactérias, sendo 7% Streptococcus pneumoniae, 43% Staphylococcus coagulase negativo, e 50% bacilos Gram negativos (21,5% fermentadores e 28,5% não fermentadores). Os resultados obtidos mostram a ação vetorial de formigas no transporte de bactérias, muitas das quais patogênicas, sugerindo que tais insetos possam representar um risco potencial à saúde.
ANÁLISE DE EMISSÕES SOLARES MÉTRICAS COM LENTA TAXA DE DERIVA EM FREQUÊNCIA ASSOCIADAS À EVAPORAÇÃO CROMOSFÉRICA
Authors: Korol Andre Rossi , Fernandes Francisco Carlos Rocha
Published: April 2021

Por meio de ferramentas computacionais desenvolvidas exclusivamente para extração e análise de dados solares obtidos pelos espectrógrafos da rede e-Callisto, foi realizada a análise de uma rádio-emissão solar registrada em ondas métricas (200 - 800 MHz), no dia 9 de agosto de 2011 (~08:32 UT). O espectro dinâmico da emissão solar gerado demonstra claramente a presença de uma lenta taxa de deriva de frequência, indício de uma frente de expansão ascendente de plasma aquecido, que caracteriza a evaporação cromosférica. A partir dos dados espectrais, uma função de ajuste para a relação entre frequência e tempo foi obtida, por meio de regressão linear e uma taxa de deriva em frequência de 1,14 MHz/s foi determinada. Então, a velocidade da frente de expansão de plasma aquecido foi estimada em 99,1 km/s (para a baixa coroa) e 369,6 km/s (para a alta coroa), adotando um modelo de densidade eletrônica para a região de emissão na coroa solar. Esses valores são comparáveis com resultados obtidos na literatura, confirmando que a rádio-emissão representa uma assinatura em ondas métricas do fenômeno da evaporação cromosférica. Por fim, ressalta-se que as ferramentas computacionais desenvolvidas se provam úteis para a extração e análise de dados de espectrógrafos da rede e-Callisto, e que por serem de código aberto, outros pesquisadores e desenvolvedores podem contribuir com alterações, correções, novas funcionalidades e até mesmo outros serviços e plataformas que as utilizem.

Authors: Barbosa Eduardo , Fernandes Arthur , Viana Rodrigo , Salomao Solange , Campos Mauro
Published: April 2021

Objective: The purpose of this study was to investigate frequency and causes of visual impairment in school-aged children from low-income areas of Sao Paulo evaluated by the “Ver na Escola” project, an initiative from São Paulo city government in partnership with a local non-governmental organization, launched aiming to offer free-of-charge visual screening and treatment to children enrolled in public schools. Methods: Vision screening included presenting VA, ocular motility, and automated dynamic refraction assessment. Children referred for the ophthalmologist were submitted to automated and subjective static refraction, best-corrected VA, slit lamp, and fundus examination. Results: A total of 17972 children were included in the study. Our findings show a frequency of visual impairment and blindness of 14.6% considering presenting VA decreasing to 1.3% after appropriate refractive correction. The main causes of visual impairment and blindness were uncorrected refractive errors (96.77%), amblyopia (0.88%), and retinal abnormalities (0.37%). Conclusion: The frequency of visual impairment and blindness in the population under study was 14.6% mainly due to uncorrected refractive errors. These results support the need for expanded and perennial refractive services through school-based programs associated with provision of spectacles. These initiatives should be sustainable and pursued by health and school authorities to provision of screening and eye care for those in need.
Covid-19: Déjà vu, all over again
Authors: Koch Tom
Published: April 2021

Since the first reports of a novel corona virus appearing in Wuhan, China, the expanding pandemic has been treated as an almost unique, unprecedented event. Both academic and popular reports have called it "unprecedented" and at best, "the worst in a century." A brief glance at history argues, however, that there is little unusual about COVID-19 except, perhaps, the rapidity of its global spread. Otherwise its clinical and social realities are familiar, similar to a host of epidemic and pandemic experiences throughout our history. What may be most notable is that our failure to recognize recurring patterns of infectious disease introduction and expansion has caused a general failure to recognize the root sources of microbial evolution and population invasion. And assuming its uniqueness today may prevent us from systemic changes to prepare for the next.
Fatigue, Susceptibility to the Common Cold and its Behavioural Effects
Authors: Smith Andrew
Published: April 2021

The aim of the present article is to describe bi-directional interactions between fatigue and infection with common cold producing viruses. Over one hundred years ago, researchers started to investigate the association between been fatigue and infection. Studies of psychological risk factors for upper respiratory tract illnesses (URTIs) have been carried out for over fifty years. Early research did not control for exposure and also often relied on self-report rather than clinical and virological assessment. Research on experimentally-induced URTIs has demonstrated that susceptibility to infection is increased by stress. Other research has shown that job insecurity, few social contacts, emotional disposition, early childhood experiences, sleep problems and self-rated health are key risk factors for infection. This article provides an interpretation of these results in terms of chronic fatigue increasing susceptibility to infection. Infection and illness also lead to changes in behaviour. These effects include greater fatigue, impaired attention and slower motor speed. Such effects occur not only when the person has symptoms but in the incubation period, with sub-clinical infections, and after the symptoms have gone. Those with URTIs are also more sensitive to other negative factors such as prolonged work, and this has implications for safety-critical jobs. Ingestion of caffeine, which is an established countermeasure for fatigue, can reduce the behavioural malaise induced by URTIs. Further support for the use of a fatigue framework comes from a secondary analysis of data on real-life colds. Previous research has demonstrated that chronic fatigue leads to greater effects of acute fatigue. The new analysis showed that those with high levels of fatigue prior to developing a cold had larger behavioural impairments when they became ill.

Published: April 2021

Chronic cervical and lumbar radicular pain represents a very widespread neuropathic pain in the population with serious repercussions on the individual and social health. To date, we do not have sufficient evidence available to allow us to make recommendations on the optimal therapy, despite the fact that various ways of treating root pain have been described over the years. Currently, conservative treatment of radicular pain relies on combined therapeutic, pharmacological and physiotherapeutic management. Interventional therapeutic procedures are reserved for those patients with root pain refractory to conservative therapies. Radio frequency (RF) can provide a good treatment option with Pulsed Radio frequency (PRF) modality. We evaluate clinical and radiologic effects of the therapeutic outcome of pulsed radiofrequency (PRF) treatment adjacent to the dorsal root ganglion (DRG) for patients with chronic intractable lumbar and cervical radicular pain in this narrative minireview, describing mechanism of action, biological effects and evidence for clinical effects and safety in recently published studies.

Published: April 2021

This paper aims to analyze the impact of Covid-19 outbreak in term of tourism sector. The Covid-19 pandemic had a tremendous impact on all countries, one of it was Indonesia, that had been affected. Many sectors are affected, including tourism. A seriously affected in tourism is the micro, medium small enterprise or called MSME sector, this has a major influence on the rate of economic growth of the country, specifically in tourism sector. The existence of this pandemic, the tourism small and medium-sized enterprises experiencing huge losses, one of it is the lack of foreign tourists coming. The method used in the research is content analysis which analyze new in media that shown the topic related to Covid-19 and tourism. In contrast to previous studies, the decline in the number of tourists was due to the reach of tourist attractions, facilities, access, and costs, this study tries to look in more detail about how the Covid-19 pandemic has a serious impact on the tourism sector. As the result, the number of foreign tourist visits or foreign tourists to Indonesia has decreased in 2020 by 28.85% compared to the number of visits in 2019. Some areas such as Bali and Yogyakarta have lost both local and foreign tourists. This has an impact on MSME providers of travel, hotels, souvenir providers, regional handicrafts, and food and drink providers in tourist areas.
Profile of Road Traffic Accident Injuries in a Tertiary Care Teaching Hospital – An Institution Based Cross Sectional Observational Study in Velammal Medical College Hospital and Research Institute, Tamil Nadu
Authors: R Kumaran , S Yogaraj
Published: April 2021

BACKGROUND Road traffic accidents (RTA) account for most of the injury patients encountered in the department of emergency resulting in significant death and morbidity. The current research was conducted to analyse the demographic, clinical and radiological profile of patients presenting with RTA to a tertiary care teaching hospital (Velammal Medical College Hospital and Research Institute). METHODS This cross-sectional observational study was done among 68 subjects presenting with RTA to the department of emergency medicine. Detailed history taking, clinical & radiological investigations including plain radiographs, ultrasound and computed tomography (CT) were done. Site of injury was considered as primary outcome of the study. The data was analysed statistically by deriving mean and standard deviation. International Business Machines Statistical Package for the Social Sciences (IBM SPSS) version 22 was used for statistical analysis. RESULTS Among the study population, the mean age was 36.18 ± 13.73 years. 83.82 % were males. Individuals aged less than 40 years of age were greatly involved in RTA. Majority (77.9 %) had abdominal injuries followed by 36.7 % with craniofacial trauma, 25 % had thoracic trauma, 17.6 % had spinal trauma, and 10.2 % had extremity and pelvic bone injuries. In abdominal trauma, spleen (26.4 %) was the commonly affected organ. Liver (25 %) and renal injuries (16.17 %) were next commonly observed. A significant difference (P-value < 0.05) was found in abdominal injuries due to different types of vehicles. CONCLUSIONS RTIs are common in the younger population. The predominance of the male population was seen. The most common organ to be injured was spleen. Proper understanding of the pattern of trauma may help in improving the outcome. Early diagnosis, aggressive resuscitation and timely surgical intervention were essential in improving the outcome in trauma patients.

Authors: Mulla Sadiq Yunus , Pandit Sachin Sitaram , Shivnitwar Sachin Kisan
Published: April 2021

BACKGROUND Haemophilia’s are X-linked hereditary blood clotting disorders due to deficiency of factor VIII (haemophilia A) or factor IX (haemophilia B) & also has identical clinical manifestations, screening tests abnormalities and sex-linked genetic transmission. Haemophilia’s result from defects in the factor VIII / IX gene that lead to decreased amount of factor VIII / IX protein, the presence of a functionally abnormal protein, or combination of both. Haemophilia A is a classic example of an X-linked recessive trait. The severity of their bleeding depends on their factor VIII activity level; and, rarely, a woman can have very low factor VIII activity, and present with symptoms of moderate or even severe haemophilia. We wanted to study the clinical profile of patients of haemophilia admitted in a tertiary care hospital. METHODS This is a cross-sectional study enrolling 60 known cases of haemophilia A & B admitted in wards & ICU / attending OPD of a tertiary care hospital. History was obtained in detail & thorough clinical examination was carried out. Precipitating factors for bleeding (spontaneous / minor trauma / major trauma / surgical operation / dental procedure / others), family h / o bleeding were studied in detail. RESULTS Of the total 60 cases of haemophilia, majority (49) of cases were of haemophilia A and 11 cases were of haemophilia B. In the study, majority (28.33 %) of cases belonged to 12 - 20 years age group and the most common presentation was haemarthrosis (61.67 %). 6 patients had factor VIII inhibitor antibodies and all of them were of haemophilia A. CONCLUSIONS Haemarthrosis is the most common clinical presentation of haemophilia and most common cause for haemarthrosis is spontaneous bleeding. Most common joint involved in bleeding was knee joint (target joint). Presence of factor VIII inhibitor antibodies specially in haemophilia A patients is not uncommon.

Purpose of the study: This research study aims to measure the entrepreneurial attitude of female university students and investigates the factors contributing to the development of entrepreneurial attitude among female students in Pakistan. The core objective of the study was to develop entrepreneurial attitudes among females and make them capable to adopt small-scale businesses. Methodology: A quantitative approach was employed to measure the entrepreneurial attitude of female students and further exploring different factors affecting the attitude of female students towards adopting the business as a career option. In this study, a survey method was used in which quantitative data on female students’ entrepreneurial attitude and different affecting factors were collected from 2576 female students from eight public sector universities located in Punjab province. The entrepreneurial attitude scale was used as a survey instrument originally developed by Ali, Topping, and Tariq (2011) and further modified by the researchers to measure the entrepreneurial attitude of female students. A factor-based scale was developed to measure the effect of these factors on female students’ entrepreneurial attitudes. The collected data were analyzed using descriptive statistics, Pearson correlation, and regression techniques by using SPSS 16th Version. Results: Findings of multiple regression analysis exhibits that the role of education is the best contributor to the female students’ entrepreneurial attitude. The other contributing factors are family support, technological assistance, business environment, and social support but their contribution is small whereas government initiatives and legal provisions were not supportive for developing entrepreneurial attitudes among female students. Applications of this study: This study can be useful for arranging entrepreneurial career development programs for the development of the entrepreneurial attitude among female students and make them capable to start their entrepreneurial endeavours. Novelty/Originality of this study: The novelty of this study was to investigate the effects of different familial, social, educational, political, environmental, and legal factors on female students’ entrepreneurial attitudes.
Ethos as a Source of Communicative Pressure Confrontation
Authors: Trofimova Valeria A.
Published: April 2021

Conflictogenic units generated by ethos transform the cooperative type of speech impact (argumentation, persuasion) into a confrontational one - communicative pressure. The formation of conflictogenic units of the ethos is due to the violation of the postulates of cooperation and maxims of politeness, which can function both independently and in various combinations. The nature of conflictogenic units reflects the peculiarities of the linguistic personality of the addressee and can serve as a basis for its identification.
Cultural Universals in A.P. Chekhov and I. Temerken’s Short Stories: Genetics and Typology
Authors: Kondrateva Viktoriya V. , Larionova Marina Ch.
Published: April 2021

For a long time Hungarian literature has been influenced by Russian literature. A.P. Chekhov’s works have been drawing a specific interest among Hungarian readers. In this regard, the question about genetic and typological ties between Russian and Hungarian literature arises. The issue in the article is considered on the example of the short story “Ferko” by the Hungarian writer, ethnographer and folklorist Istvan Temerken and the “steppe” works of A.P. Chekhov. For many Hungarian writers Chekhov’s literary works became a model which they relied on during the search of new art forms. I. Temerken grew up in a steppe region of Hungary and the “steppe” theme was especially close to him. The story “Ferko” is written in Chekhov’s manner. The place of the action is the steppe, the main character is a boy, as if separated from everyone who is next to him, the image of the road and a number of other elements of the art world of the short story allow you to notice strong similarities in the story “Ferko” and “steppe” works of Chekhov (especially in the story “Steppe”). However, Temerken could not read “Steppe” translated into Hungarian, since the story was translated after the writer’s death. It means that apart from a direct orientation to the Chekhov’s style and poetics, there should be something in the field of typological rapprochement of cultures, which explains this similarity. A.N. Veselovsky called this phenomenon “counter courses”. And modern researchers explain then as archetypes or cultural universals common to all cultures. In the works of Temerken and Chekhov such are the images of a child, steppe, sun, etc.

Many trace elements are associated with organic matter. The total organic carbon (TOC) content can be thus calculated basing on the chemical composition measurements. The aim of the presented paper was to evaluate the possibility of estimating the organic matter amount on the basis of trace elements such as: Ni, Cu, Mo, U, V, Zn, Cr, Sr, Pb and Co, for Silurian black shales. Correlations between individual elements and total organic carbon were analysed. Next, mathematical models allowing to calculate the amount of organic matter based on the content of elements significantly related to TOC were constructed. Both more accurate chemical composition analyses (ICP-MS mass spectrometry method) and measurements of lower detectability performed with portable X-ray fluorescence spectrometer EDXRF were used. The relationships between the content of trace elements and the total organic carbon content TOC were found for such elements as: V, Cu, U, Ni, Mo, Cr (ICP-MS) and V, Cu , Cr and Ni (XRF). Mathematical models allowing for TOC quantification based on trace elements, characterized by determination coefficients R2 from 0.84 to 0.92 (for ICP MS method) and from 0.75 to 0.78 (for XRF method) were obtained with the use of the multiple regression method. The mathematical models allow to calculate the content of organic matter TOC for Silurian black shales on the basis of trace element data obtained by both mass spectrometry ICP-MS and X-ray fluorescence spectrometry EDXRF. The possibility of using measurements made with a portable X-ray fluorescence spectrometer is particularly important. Such measurements are fast and can be carried out on cuttings during the drilling process. Models based on XRF results therefore allow for quick modelling of the TOC content during the drilling process.

The immune system as a whole plays a leading role in the formation of an adequate immune response during the onset and development of tumors. The aim of the study was to reveal the features of the change in the morphology and level of biogenic amines of the thymus of rats during experimental carcinogenesis of breast cancer by the injection of N-methyl-N-nitrosourea. In the work used luminescence-histochemical, general histological and immunohistochemical methods, which made it possible to obtain important information about the functional activity of the cellular elements of the thymus, the quantitative composition of macrophages, dendritic cells, lymphocytes and the qualitative characteristics of mast cells. The experiment was carried out on 85 white nonlinear female rats, which were injected with the carcinogen N-methyl-N-nitrosourea, which induces a breast tumor. Animals were divided into two groups: intact (n=30) and rats injected with a carcinogen (n=45). The thymus structure was examined 1, 2, and 3 months after the end of the injections. During the study, changes in the morphometric parameters of the organ are noted. A month after the injection of the drug, the area of the medulla of the thymus and the thickness of the cortex substance of the organ increases, which decrease with an increase in the study period. Replacement of the thymus parenchyma with adipose and connective tissue begins after 2 months and progresses with an increase in the study period. A tendency to wavelike changes in biogenic amines was revealed, after 1 month there is a significant increase in the level of histamine and a decrease in serotonin and catecholamines, after 2 months an increase in all biogenic amines, especially histamine (1.5 times or more) in premedullary and mast cells, thymocytes of the cortex. After 3 months, on the contrary, there is a decrease in histamine and an increase in the level of monoamines. The ratio (serotonin+histamine)/catecholamines after 1 month indicate a decrease in the functional activity of the thymus, and after 3 months - about its increase. At all stages of the study, degranulated forms of mast cells predominate. In the dynamics of the experiment, an increase in the number of dendritic cells, lymphocytes, and twice the number of macrophages and Bcl-2+cells was revealed. The data obtained in the course of the study suggested that the introduction of N-methyl-N-nitrosourea and the subsequent development of a breast tumor is reflected in the change in the morphofunctional state of the thymus. In this case, the greatest changes were observed 2 months after the end of the administration of the carcinogen, even before the formation of a breast tumor. The data obtained can have a certain value in determining the immune status in models of experimental carcinogenesis.
THE MORPHOLOGICAL EVALUATION OF THE EXPERIMENTAL MODEL OF SYSTEMIC GENERALIZED THROMBOSIS
Authors: Bashirova Linara I.
Published: April 2021

The only regulated model of disseminated intravascular coagulation syndrome or disseminated intravascular coagulation syndrome is the Di Minno model of generalized thrombosis. Due to the expansion of the role of tissue factor and thrombin in the initiation of DIC, the aim of this study is the histological assessment of the Di Minno model under conditions of DIC initiation by tissue factor or thrombin with comparison with the classical variant. The study was performed on 80 male mice. All laboratory animals were divided into three groups depending on the trigger of thrombosis: Group I - collagen + adrenaline solution (0.5 mg / kg + 0.06 mg / kg), Group II - 10 mg / kg thromboplastin, Group III - 10 mg / kg thrombin. Histological studies of animal’s preparations demonstrate a lower content of blood clots in the lungs of laboratory animals, which suggests that the main cause of death of animals is not acute thrombosis, but the development of delayed manifestations of DIC when using tissue factor. In the case of thrombin using, on the contrary, the death of animals is recorded on the first day of the experiment and the results of the histological study demonstrate the massiveness of thrombosis, which is not initially provided for by this model, calculated to assess the effectiveness of new antiplatelet drugs in an acute experiment. Thus, on the basis of morphological studies, the limitations of the use of tissue factor and thrombin in model thrombosis have been demonstrated and the expediency of using physiological inducers of aggregation has been substantiated.
THE MORPHOGENESIS OF NONPARASITIC LIVER CYSTS
Authors: Freynd Genrietta G. , Zhivaeva Elena V
Published: April 2021

As a result of the introduction of imaging research methods into clinical practice, the frequency of detection of cavities in the liver has significantly increased, among which nonparasitic cysts have not been sufficiently studied. The paper provides an overview of the most commonly used classifications of this pathology. Clinical and radiological manifestations of cysts were investigated based on the analysis of the results of computed tomography, magnetic resonance imaging and ultrasound sonography of 175 patients (109 with solitary cysts and 66 with polycystic liver). The tissues of the resected areas of 81 cysts and adjacent liver tissue were studied by histological and immune-histochemical methods. Various variants of liver cysts were identified: polycystic cysts, solitary cysts and the rarest variant - ciliated anterior-intestinal hepatic cysts. The morphological and histogenetic features of solitary and ciliated anterior-intestinal hepatic cysts, as well as changes in the liver tissue adjacent to the cavities, are described. Polycystic is characterized by the presence of cavities of various sizes, with thin connective tissue partitions and a lining of cubic or flattened epithelium. The lining of solitary cysts is represented by cubic, cylindrical, sometimes multi-row epithelium. Immature biliary structures in the form of von Meijenburg complexes, islets of hepatocytes, conglomerates of dysplastic vessels are revealed in their wall among the cells of connective tissue. Ciliated anterior-intestinal hepatic cysts contain components of the primary intestine wall - a lining of a cylindrical ciliated epithelium, a layer of loose connective tissue, a muscle layer, a connective tissue capsule. Morphological studies made it possible to establish violations of embryogenesis in various types of cysts. Ciliated anterior intestinal hepatic cysts develop from the anterior section of the primary intestine, while solitary cysts are derived from its middle section. Migration of the developing buds of bronchioles from the cranial part of the primary midgut into the hepatic diverticulum determines the presence of all components of the wall of the hollow organ - cylindrical ciliated epithelium, loose connective tissue, bundles of smooth muscle fibers. Simple solitary cysts are the result of abnormal remodeling of the embryonic ductal lamina, thus being a developmental abnormality of the middle section of the primary midgut. Morphological examination of the liver tissue adjacent to the walls of the cysts reveals hypoplasia of lobules, persistence of elements of the embryonic ductal plate in the form of cords and complexes of the biliary epithelium, foci of ductopenia, von Meijenburg complexes, and various variants of vascular dysplasia.

Investigation which devoted to the study of the age characteristics of the human body are becoming increasingly important. Magnetic resonance tomography is the most informative diagnostic method for intravital visualization of tissues and structures of the brain. It also allows you to more accurately see the picture of morphological features with age-associated changes. The aim of the study was to carry out a comparative analysis of the age-related morphometric characteristics of the cerebellum in male with mesocranic type of cranium in young and old age according to the data of magnetic resonance tomography. The analysis of the results of a morphometric study of the cerebellum on tomograms of 91 men examined for medical reasons was carried out. Depending on the age, the subjects were divided into two groups. Group I included 52 young men (22–27 years old, inclusive), group II included 39 elderly men (from 78 to 83 years old, inclusive). The transverse, longitudinal and vertical dimensions of the cerebellum were determined. When comparing the parameters of the linear dimensions of the cerebellum in the studied age groups of men, a statistically significant decrease in all indicators in old age compared with young age was revealed (p=0.042). There was no statistically significant difference between the parameters of the longitudinal and vertical sizes of the cerebellar hemispheres in individuals of each age group (p>0.05); there is a tendency for these sizes to prevail in the right cerebellar hemisphere. The results obtained can serve as the equivalent of the age-related anatomical norm of the cerebellum in young and old men, which will make it possible to use these data in basic and clinical research, as well as in medical practice.

A Educação do Campo tem sido no Brasil tema bastante problematizado no Brasil nos últimos anos. Embora tenha conquistado nos últimos anos avanços significativos por meio da criação de programas como o PRONERA e o PROCAMPO, vêm passando por inúmeros desafios quanto ao acesso e à permanência do jovem e do adulto camponês na universidade. A partir de uma perspectiva bibliográfica e empírica, esta pesquisa tem como objetivo principal apresentar uma compreensão da Educação do Campo enquanto uma educação voltada às especificidades dos povos que moram e trabalham no campo, tendo como parâmetro a experiência com as LEDOC da UFT em Tocantins. Para as análises dos dados, o estudo seguiu a perspectiva do Materialismo Histórico e Dialético. O indígena, o quilombola, o ribeirinho, o assentado, os atingidos por barragens, o agricultor familiar, o extrativista, entre outros que vivem e produzem as suas condições materiais de sobrevivência no campo, vão para a universidade não porque eles sejam obrigados, mas porque têm interesse e necessidade de aprender. Acessar e frequentar a universidade é estudar num lugar que foi negado historicamente para eles. É enfrentar uma realidade que os exclui, com o objetivo de superá-la. Consideramos, enfim, que a materialidade dos cursos da LEDOC da Universidade Federal do Tocantins configura uma realidade recente na realidade educacional brasileira e constitui-se como uma nova modalidade de graduação conquistada a partir das reivindicações dos movimentos sociais, cuja expansão se deu prioritariamente nos governos dos presidentes Lula e Dilma.

Para tanto, buscou-se investigar mais a fundo qual o posicionamento da política externa brasileira no momento de concepção do programa, depois buscou-se compreender os motivos reais que proporcionaram a criação do PEC-PG e por fim, buscou-se investigar a concepção de Cooperação Sul-Sul e observar em que medida ela se distancia do modelo comum de cooperação e descobrir se o Programa Estudantes Convênio de Pós-Graduação (PEC-PG) poderia ser considerado um programa de cooperação que atende aos princípios que balizam a Cooperação Sul-Sul. O desenvolvimento do trabalho se deu através de buscas documentais, periódicos, teses e livros, o paradigma adotado foi o interpretativista, uma vez que o sujeito vê o mundo social na forma de um processo social criado pelos indivíduos envolvidos. Como considerações finais, foi possível observar que o PEC-PG foi criado ensejando auxiliar o desenvolvimento econômico nacional da época e que, embora seja um programa de cooperação entre os países do Sul, não pode ser caracterizado como um programa que atende aos princípios da Cooperação Sul-Sul, pois algumas prerrogativas do programa se distanciam do proposto pela CSS.
(In)visibilizados e (in)dizíveis da/na vida estudantil na univers/cidade

Published: April 2021

Este texto tem por objetivo analisar enunciados verbais e imagéticos, respostas de estudantes às vozes sociais que produzem os espaçotempos, condições e possibilidades da/na vida acadêmica universitária e que expressam alguma forma de sofrimento. Esses enunciados, diálogos (transcritos) e fotografias, foram produzidos no contexto de Oficinas de Fotografia, que compuseram uma pesquisa-intervenção de doutorado em psicologia, por estudantes de graduação (num total de 16 participantes) de uma universidade federal brasileira. Discutimos sobre esses enunciados como produto/reflexo de exclusão no contexto acadêmico universitário que é, na maioria das vezes, silenciado e invisibilizado em meio a lógicas de produtividade, custos, rankings, entre outras. Concluímos sobre a necessidade de construção de espaços em que as vozes das/os estudantes possam circular, ser ouvidas/lidas, para que possam auxiliar, de forma efetiva, na construção das universidades e das condições e possibilidades da vida acadêmica.
Biodiversity databanks and scientific exploration
Authors: Barberousse Anouk
Published: April 2021

For several decades now, biologists have been developing digital databanks, which are remarkable scientific instruments allowing scientists to accelerate the development of biological knowledge. From the beginnings of the Human Genome Project (HGP) onwards, genetic databanks have been a major component of current biological knowledge, and biodiversity databanks have also been developed in the wake of the HGP. The purpose of this paper is to identify the specific features of biodiversity data and databanks, and to point out their contribution to biodiversity knowledge.
Une ontologie dispositionnelle du risque
Authors: Grenier Olivier , Barton Adrien
Published: April 2021

Le risque est une entité omniprésente dans le domaine biomédical. Une caractérisation ontologique cohérente du risque est donc nécessaire pour faciliter l'échange et le rassemblement des données informatiques du domaine biomédical à des fins cliniques et des fins de recherche à l'aide d'outils nommés « ontologies appliquées ». Nous analysons certaines définitions du risque et en tirons deux traits généraux que le risque partage avec les dispositions. Nous proposons par conséquent une définition du risque comme une disposition dont la réalisation est indésirable pour un agent. Cette définition permet de concilier la dimension objective et la dimension subjective du risque : un risque existe indépendamment de notre connaissance de celui-ci, mais le statut de risque d'une disposition pour un agent dépend des préférences de cet agent.

Impacto de la inteligencia artificial en los procesos de selección en recursos humanos internacionales
Authors:   , Montoya Bello María Belén
Published: April 2021

La inteligencia artificial puede llegar a ser un uso esencial para los procesos de selección. Cabe recalcar que las empresas que tienen grandes cantidades de ceses de personal es una problemática utilizar el método tradicional de selección porque todo proceso requiere tiempo para poder escoger un candidato, mientras que tener como complemento una herramienta como la inteligencia artificial puede llegar a ser muy útil y necesario para optimizar tiempos, dinero y principalmente eliminar el sesgo humano. Es por ello que se realiza un estudio para obtener información de empresas ubicadas en Perú sobre la efectividad de esta herramienta en sus procesos de selección. Se trata en brindar información útil a todo aquel profesional de recursos humanos o empresas que tengan inconvenientes o alguna problemática en sus procesos de selección, para considerar esta herramienta dentro de sus procesos. La investigación se basa en una descriptiva correlacional y explicativa no experimental, en el cual se obtendrán datos concisos y certeros, con ayuda de las técnicas de un cuestionario y entrevistas a profundidad.

La investigación propone la rúbrica pedagógica para contribuir en el desarrollo de la evaluación formativa en los estudiantes de Educación Secundaria de una institución educativa privada para la mejora del proceso de aprendizaje. Por su naturaleza, metodológicamente, el tipo de investigación es aplicada educacional, con un enfoque cualitativo dentro del paradigma interpretativo. La muestra de estudio está conformada por 20 estudiantes y 3 docentes del área de Comunicación, seleccionados mediante la técnica del muestreo no probabilístico, a través de entrevistas, encuestas, observación y análisis. En el diagnóstico pedagógico se emplean diferentes técnicas e instrumentos que brindan información objetiva acerca de las potencialidades y las carencias que presentan en el proceso de enseñanza- aprendizaje en el uso de la evaluación formativa. Así, el resultado más importante está en que los docentes desarrollen la evaluación formativa para poder formar integralmente a sus estudiantes, donde puedan regular su aprendizaje en el proceso educacional con la planificación, monitoreo, evaluación de aprendizajes, el trabajo colaborativo y logren aprendizajes significativos con una adecuada mediación docente. Dado el fundamento científico de diferentes ciencias que inciden en el objeto de investigación, la rúbrica pedagógica se convierte en una herramienta de un valor extraordinario para que el docente dirija el proceso enseñanza - aprendizaje desde perspectivas flexibles y abiertas, en donde se involucra a los estudiantes en su propio proceso evaluativo para contribuir en la mejora de sus aprendizajes y por ende en su formación integral.

Interaction of Global Crisis and Social and Political Thought
Authors: Bogomolov O.
Published: April 2021

The relative weakness of the modern social and political thought is especially visible against the background of the global economic crisis and historical changes in the world. We see a trampling on outdated ideological and historical positions, as well as a lack of the ability to produce a generalized vision of the new trends and realities of social life, correctly assessing their meaning, direction, possible consequence. Most importantly, there is a failure to offer an adequate practical political vector of actions. The definition of the post-reform model of social and political system remains an urgent problem for Russia as well. Academic thought must provide political and economic practice by adequate indicators enabling to evaluate spiritual, moral and physical health of the society, efficiency of the governmental apparatus, the quality and professionalism of managers.
Is Iraq Drama Going to End?
Authors: Mirskii G.
Published: April 2021

The withdrawal of American troops from Iraq marks the beginning of a new stage in the history of that country. Iraq once again becomes a sovereign independent state. From now on, the huge task of ensuring security and putting an end to the terrible internal strife must be entrusted to the local authority. It is crucial to find a compromise solution to the Sunni-Shiite conflict. To achieve this end, the central power has to be really inclusive, giving the Sunnis their legitimate place in governing the country. The worst scenario would be the establishment of a Shiite-dominated regime that is prone to neglect the grievances of the Sunni population. The rights of the Kurdish minority, too, have to be safeguarded unless the state falls apart. Judging by their past behavior, however, it is hard to believe in the goodwill and adequate judgment of Iraqi politicians. The author concludes that the situation may well get worse before it starts to better off.
Social and Political Factors of Russia’s Investment Image Formation
Authors: Rabotyazhev N.
Published: April 2021

The article is devoted to the investigation of key social and political factors forming Russia’s investment image. The author notes that investment attractiveness of Russia is now on a low level and tries to discover the causes of this phenomenon. In the article the meaning of such concepts as “investment image”, “investment climate”, “business climate” is explained. The author stresses that improvement of the investment climate in the country is the precondition of the change for the better of its investment image. Examining main factors of political risk in Russia he arrives at a conclusion that these factors are connected with the peculiarities of the present model of Russian “crony” capitalism combining the elements of bureaucratic and speculative trade capitalism. In the author’s view, the uncontrolled rule of bureaucracy, reinforced by “statism”, to a considerable extent deteriorates the investment climate in Russia. Thus, a conclusion is drawn that the modernization of political system is an important prerequisite of improvement of Russia’s investment image.
