A condição da docência universitária no contexto atual das universidades: marcas históricas, realidade e perspectivas
Authors: Brito Talamira Taita R. , Cortela Beatriz Salemme C.
Published: June 2020

O artigo tem como objetivo refletir sobre alguns aspectos teóricos acerca da condição da docência e dos docentes universitários, seus saberes, seu trabalho e as relações construídas historicamente com esse fazer. Apresentamos um percurso da consolidação do ideário da universidade pública brasileira e os desdobramentos na costura da docência universitária como condição diferenciada para se realizar o trabalho, entendido por nós como sendo o ambiente de desenvolver-se profissionalmente, ao mesmo tempo em que é o lócus provocador de mudança da própria universidade, da própria condição docente e de sua relação com a sociedade. O projeto inacabado de universidade pública brasileira está sujeito, mais uma vez, ao enfrentamento da lógica do neoliberalismo, de aligeirar-se, despir-se de tempo para conhecimento, para produção, para qualidade do fazer pedagógico, na medida que sua pouca autonomia conquistada começa a ser retirada através do falso discurso da não ou da baixa produtividade a serviço do mercado e das demandas do capital não atendidas. O impacto dessas ameaças está diretamente ligado à conformação que a docência assume e submete-se para tentar sobreviver. Professores cansados, desanimados, produzindo, muitas vezes, trabalhos com qualidade duvidosa e submetendo-se às péssimas condições de trabalho, salários que não correspondem com a condição e exigência da profissão, ou, ainda, editais que nem sempre aportam recursos que validem um montante significativo de financiamento para pesquisa e ou para o aumento no número de pesquisadores, põem a mostra da realidade atual, que carece de mudanças conceituais sobre o que é a universidade e de suas condições para construir a docência universitária.
Competitive environment and corporate constructs of price and costs in the UAE
Authors: Zanella Fernando , Oyelere Peter
Published: June 2020

Target costing is a cross-disciplinary subject with several unexplored academic dimensions besides having applied business practices and economic policy implications. In this paper, we use a unique combination of mixed methods research approach to investigate the adoption of target costing by manufacturing firms in the United Arab Emirates (UAE). The first employed method is the new Dumitrescu-Hurlin (D-H) Granger non-causality test for heterogeneous panel data, while the second is a survey. The D-H test with annual data indicates the adoption of target costing by the publicly listed manufacturing firms. When using quarterly data, but with a smaller sample of firms, the results show bi causality between costs and sales revenues; thus target costing is possibly corroborated but within a feedback mechanism. Survey results, based on self-reported data and again on a smaller sample, show mixed results. The relationship between target costing and the intensity of competition seems moderately corroborated by the survey results. This paper contributes to the literature by employing a unique mixed methods research approach, to the best of our knowledge not found previously in the literature, and by its findings on the adoption of target costing by manufacturing firms in a relatively open and dynamic economy such as the UAE.
DESIGN OF A MODEL REFERENCE ADAPTIVE PID CONTROLLER FOR DC MOTOR POSITION CONTROL: COMPARED WITH PID AND FUZZY CONTROLLERS
Authors: ÇAKAR Yasin , ORMAN Yıldıray , KİZİR Selçuk
Published: June 2020

Sometimes conventional feedback controllers may not perform well due to changes in environmental conditions, changes in process dynamics that occur over time and changes in characteristics of disturbances. To overcome these problems, adaptive control methods have been developed. In this regard, a Model Reference Adaptive PID Controller (MRAPIDC) is designed using the MIT rule for position control of the DC motor in this study. At the same time, this control method is implemented using a low cost STM32F4 application development kit with Matlab-Simulink supported Waijung block set and compared with PID and fuzzy logic control methods. The results obtained with/without measurement noise disturbance under unit step and sinusoidal inputs are presented.

Authors: Orac D. , Laubertova M. , Piroskova J. , Klein D. , Bures R. , Klimko J.
Published: June 2020

Various types of waste, including dusts, are produced in the pyrometallurgical production of copper from secondary raw materials. According to the European Waste Catalogue and Hazardous Waste List, dusts from secondary copper production are classified as hazardous waste. In secondary copper production 3.87 million tons of copper were produced worldwide in 2017. The dusts are produced in the following thermal operations: reduction of the melt in the shaft furnace (shaft furnace dust), converting (converter dust), and pyrometallurgical refining (refining dust). These dusts contain significant amounts of heavy metals (Zn, Pb, and Sn) in oxidic forms. The dusts are regarded as secondary raw materials, and it is necessary to look for ways of extracting these heavy metals. The aim of this work was to characterize the individual types of dust and determine their quantitative and qualitative composition. The content of heavy metals in copper shaft furnace dust is (52.16% Zn, 19.33% Pb), in copper converter dust (32.40% Zn, 14.46% Pb), and in refining dust (32.99% Zn).

Authors: Zhao D.-Q. , Yang S.-H. , Chen Y.-M. , Tang C.-B , He J. , Li H.
Published: June 2020

The leaching behavior of hemimorphite in neutral solution (NH4 +-Cl--H2O) was investigated at high temperature (T > 100?C) under a range of experimental conditions. Thermodynamic calculations indicate that the tendency of dehydration of silica gel is significantly enhanced with the increasing temperature. It was shown that the temperature, ammonium chloride concentration, or L/S ratio increased resulted in greater leaching efficiency. The following optimized leaching conditions were obtained: stirrer speed 400r/min, NH4Cl concentration 5.5M, L/S ratio 9mL/g at 160?C for 3h. Under these optimized conditions, the average leaching yield of zinc was 97.82%. The silicon was converted to quartz and remained in the residue. This process can be used to dispose willemite and hemimorphite as it solves the problem of silica gel dehydration.

Authors: Fan Y.-Y. , Liu Y. , Niu L.-P. , Jing T. , Zhang T.-A.
Published: June 2020

The purpose of this study was to select and propose an applicable method for extracting lead from sphalerite concentrate direct leaching residue. A large number of experiments were conducted to extract lead from sphalerite concentrate direct leaching residue by hydrochloric acid and sodium chloride solution as leachates. The main optimum parameters were determined, such as a liquid-solid ratio of 17.5-1, a reaction temperature of 85?C, an initial hydrochloric acid concentration of 1.3 mol/L, an initial sodium chloride concentration of 300 g/L, and a reaction time of 60 min. Ninety-five percent of the zinc, 96.0% of the iron, and 93.7% of the lead were extracted into leachate at the optimum conditions. The lead in the leachate was in the form of [PbCl4]2-. After the leachate was purified to remove impurities, it was converted into lead oxalate by sodium oxalate as a precipitant. Finally, lead oxalate was decomposed to obtain lead oxide powders via a high-temperature calcination process.
Assessing the dimensionality of three LMX instruments within a diverse cultural and linguistic context
Authors: Grobler Anton , Mathafena Rose
Published: June 2020

Multiple versions of the Leader-member exchange (LMX) instruments are widely utilized for exploring the quality of exchange between the leader/supervisor and the employees in leadership studies. Despite widespread usage, validation studies outside the USA are scarce. The purpose of this study was to analyze the psychometric properties of three versions of LMX instruments in the South African context. The factor structure, validity, and reliability of the respective versions were explored. The sample comprised of employees from the private (3598) and public (2640) sectors, from 106 organizations, across three independent studies. A three-factor structure was reported for 11 and 12 item instruments, which is different from the original four factor structure. The unidimensional 7 item instrument reported exceptionally good fit. The results of this study are useful for leadership researchers within the South African context, as they can use the LMX instruments with confidence, but it raises a question about the common practice of using foreign developed instruments for research purposes without testing its transferability to that specific context.
How to Publish in Peer-Reviewed Practitioner Accounting Journals
Authors: Boyle Douglas M. , Boyle James F. , Hermanson Dana R.
Published: June 2020

The three of us devote a significant portion of our research time to publishing in peer-reviewed practitioner accounting journals, in addition to our focus on traditional academic journal publishing. In this article, we first discuss overall considerations when publishing for practitioners, including finding topics, writing, statistics, and implications. Then, we describe the five types of practitioner papers we typically produce and how we develop each type of paper: small literature reviews, empirical papers, thought pieces, skills papers, and current topic updates. We conclude with discussion of related educational opportunities and issues, including using practitioner articles in class, exposing doctoral students to practitioner publishing, and getting academic credit for practitioner publishing in tenure, promotion, and annual performance reviews. At a time when accounting academia is seeking to enhance the relevance and impact of research, we hope this paper will prompt other academics to begin or increase their contributions to practitioner journals.

Números reais no contexto de uma comunidade escolar surda: um estudo com ênfase em registros figurais
Authors: Souza Lucas José de , Mariani Rita de Cássia Pistóia
Published: June 2020

O presente artigo objetiva analisar mobilizações de representações semióticas de números reais, a partir de registros figurais, por estudantes surdxs que cursam o 1º ano do Ensino Médio de uma escola pública de Educação Bilíngue localizada em Santa Maria – RS. Para tanto, desenvolve-se uma sequência composta por sete tarefas, envolvendo o material manipulável tangram, bem como régua e compasso. A pesquisa se ampara na metodologia qualitativa, sob a forma de estudo de caso, seguindo critérios da análise de conteúdo. Como referencial adotam-se pressupostos dos registros de representação semiótica, que permitem estabelecer análises cognitivas para compreender articulações de sistemas representativos. Em consonância com a análise de conteúdo, foram estabelecias quatro unidades de registro para compor as categorias: representações fracionárias de números racionais; representações decimais e percentuais de números racionais; representações geométricas de números reais e representações icônicas de números reais. Conclui-se que as representações icônicas das formas do tangram oportunizam transformações, que mobilizam sistemas de representação numérica para números irracionais e fracionária para números racionais. Esse viés é subsidiado, respectivamente, ao analisar medidas de lados, com apoio de comparações entre peças e suporte ao teorema de Pitágoras, e ao determinar áreas de figuras planas, por meio de uma relação parte-todo desencadeada a partir do recurso. Ademais, o desenvolvimento das tarefas contempla a mobilização de uma diversidade de registros semióticos, ao envolver atividades que exploram representações numéricas decimais e percentuais, além de representações geométricas, pela localização de pontos na reta. Nesse sentido, são analisadas distintas características do objeto matemático números reais, conforme os conteúdos evidenciados em cada um dos sistemas representacionais envolvidos. Essa forma de acessar conceitos permite a estruturação do conhecimento matemático, através de relações entre qualidades que as representações anuem, não se limitando ao inócuo estudo de regras e fórmulas.

GRAFOS: uma nova visão da relação de Euler e os Poliedros regulares
Authors: Barros da Trindade Anna Karla , Araújo Júnior Francisco de Paula Santos de , Nascimento Fabiano dos Santos
Published: June 2020

No objetivo de transformar o ensino de matemática mais atrativo para os alunos, e, também para os professores de matemática da educação básica, foi proposto um estudo mais sofisticado sobre a relação de Euler e os sólidos platônicos (conhecidos também como poliedros de Platão). A relação de Euller sem duvidas é um resultado bastante importante na matemática assim como a demonstração da existência de apenas cinco poliedros regulares. No entanto, estes resultados são bastante previsíveis, pela forma que os professores ensinam este tópico nas escolas, deixando as aulas de geometria desestimulantes aos alunos. Sendo assim, na perspectiva de enriquecer o ensino de geometria no ensino médio, buscou-se inserir uma nova forma de demonstrar a relação de Euler e os poliedros regulares, introduzindo assim uma ferramenta pouco conhecida no ensino médio, teoria dos grafos. Tais demonstrações não possuem artifícios tão diretos, porém, foi necessário introduzir esse estudo com alguns conceitos e exemplos importantes como poliedros, poliedros convexos e não convexos, poliedros regulares, grafo, grau de um vértice, grafos Eulerianos, grafos conexos, grafos planares, isomorfismo entre grafos, grafos regulares e alguns teoremas relevantes. Como consequência desse estudo, foi possível perceber que a relação de Euller e os poliedros regulares podem ser ensinados de maneira simples e interessante com a utilização dos grafos.

Published: June 2020

O presente trabalho trata das desigualdades no acesso à terra urbana no Recife, em terras da União. Evidencia que, por um lado, os entraves para o reconhecimento do direito à moradia da população de baixa renda em assentamentos informais são evidentes; por outro lado, quando há o interesse do capital, o uso da terra urbana não só é permi­tido, como o processo de mudança de titulação é célere. Buscou-se a análise das dinâmicas que reproduzem a desigualdade social no acesso à terra urbana a partir de dois estudos de caso: a comu­nidade do Coque, assentamento que ainda não foi regularizado na área central da cidade e de grande valorização imobiliária, que lhe confere vulnerabili­dade fundiária; e o condomínio Le Parc Boa Viagem, empreendimento imobiliário para a classe de alta e média renda, localizado próximo a uma área de preservação ambiental.
Múltiplas faces do feminismo marxista
Authors: Severo Cecília
Published: June 2020

O marxismo e o feminismo têm um histórico de alianças e desavenças, no qual muitas vezes o feminismo ou a “questão das mulheres” foi incorporada às pautas e teorias marxistas para, em seguida, serem subjugados e tornados preocupações políticas e epistemológicas de segunda instância. Buscamos uma articulação mais funcional entre feminismo e marxismo, que seja simultaneamente ambos, a partir de uma investigação da obra da brasileira Heleieth Saffioti e da italiana Silvia Federici. Nos concentrando em A mulher na sociedade de classes acompanhamos as análises de Saffioti sobre a constituição do capitalismo brasileiro e a posição da mulher nele, seguindo seu argumento sobre a integração parcial das mulheres no modo de produção. Na sequência, desenvolvemos as análises de Federici, sobretudo em Calibã e a bruxa, sobre a formação do capitalismo através do cercamento dos comuns na Europa e sua relação com a expropriação do trabalho reprodutivo exercido pelas mulheres. Por fim, comparamos as perspectivas das duas, tendo como foco problemático o modo como cada uma lida com a relação entre trabalho e a posição das mulheres no capitalismo. Enquanto Saffioti pensa em termos de integração parcial e periferização social das mulheres tendo em vista sua semi-exclusão do “mundo do trabalho”, Federici vai mais longe ao tomar como central a importância do trabalho reprodutivo feminino percebendo como as mulheres são antes partes essenciais do processo de produção capitalista, ainda que seu trabalho seja não pago e não reconhecido enquanto tal.

Cartel soviético de la época postrevolucionaria (1917-1932)
Authors: Yashina Ekaterina
Published: June 2020

Este artículo tiene como objetivo acercar al lector al cartel soviético como forma de expresión artística. Para comprender la relevancia del cartel soviético es necesario hacer una aproximación al contexto en el que se desarrolla. Los artistas se encuentran al servicio del Estado y su función es hacer llegar su mensaje a toda la población. El arte gráfico soviético destaca por el empleo de cartel de agitación como medio para difundir la ideología bolchevique, y como toda forma artística, tiene unos antecedentes, en ocasiones, inesperados. El arte tradicional ruso se convierte en el punto de partida para el desarrollo de los carteles. Los artistas se sumergen en la investigación y redescubrimiento de sus propias raíces, potenciándolas y reforzándolas y, de este modo, se produce un acercamiento a la sociedad rusa a través de elementos que ya conocen.
Arte plumaria en el siglo XIX: el Emblema Nacional, un nuevo motivo iconográfico para el México republicano
Authors: Báez Hernández Montserrat Andrea
Published: June 2020

El arte plumaria, manifestación artística de origen prehispánico, continúa maravillando tanto por la delicadeza de su materia prima como por el altísimo grado de perfección alcanzado por los amantecas, artífices de la pluma. Las plumas eran consideradas en el México prehispánico un material precioso revestido de simbolismo estético y religioso, íntimamente ligado a la vida espiritual y ritual. El amantecayotl, la fina técnica de mosaico plumario que llegó a la cúspide de su perfección en el siglo XVI, continuó floreciendo tras la caída de Tenochtitlan y durante la dominación española, aunque para el siglo XIX únicamente sobrevivió en pequeños núcleos de producción circunscritos al occidente mexicano. El propósito de este artículo es llamar la atención sobre la supervivencia de esta manifestación artistica en el siglo XIX a través de un primer acercamiento tecnológico e iconográfico a una pieza producida en dicha centuria. Asimismo, se propone la revaloración de los objetos plumarios decimonónicos, cuyo estudio se encuentra aún pendiente en la Historia del Arte en México.

Due to the current epidemiological situation caused by the spread of the new SARS-CoV-2 coronavirus, in March 2020 several Moscow hospitals were completely or partially redesigned to receive patients with community- acquired pneumonia.

Purpose. The aim of the survey is to analyze clinical, laboratory and radiological data in patients with coronavirus infection at the early stages of its spread in Russia, and to clarify diseases for differential diagnosis mainly based on CT evidence.

Materials and methods. We studied data from 21 patients with verified coronavirus infection admitted to the hospital for community-acquired pneumonia. Clinical symptoms, laboratory and physical indicators, as well as typical lung changes on the CT were evaluated.

Results. Major clinical symptoms in coronavirus patients are fever (100%), cough (90.5%), shortness of breath (76.1%). Laboratory indicators showed increases in CRP (85.7%), leukocytosis (66.6%), and LDG (84.6%). According to CT, 95.2% of lung changes involved both sides, and 66.7% occurred in all lung fields. The sign of “ground glass” was observed in a 100% of the cases, its combination with the “paving stone” – in 61,9%, “ground glass” coupled with small areas of consolidations were detected in 33,3% of the cases. Changes such as nodules, cavities and massive areas of consolidation were not identified.

Conclusion. On the basis of our own data we confirmed the main trends of diagnostics and clinical features, which were identified by authors from Asia and Europe, who faced this infection earlier, and also considered important CT characteristics useful for differential diagnosis of coronavirus lung damage and other lung diseases.

Published: June 2020

Purpose. Review and analysis of the available foreign literature about CT findings in patients with COVID-19 pneumonia after treatment with tocilizumab.

Material and methods. 6 publications were analyzed that were available for the keywords “COVID-19”, “radiology”, “CT”, “tocilizumab”, “cytokine release syndrome”, “interleukin 6”, “IL-6”. Search was limited only to English language manuscripts with no time limit. The literature search was last done on 3rd June 2020.

Results. There is a small number of studies on CT findings of COVID-19 pneumonia during the treatment of actemra (tocilizumab). At the request of “COVID-19”, “radiology”, “CT”, “tocilizumab”, “cytokine release syndrome”, “interleukin 6”, “IL-6” in the database of medical and biological publications “PubMed” on 03.06.2020 can be found only 8 publications that would satisfy the search query. At the time of writing this article we were able to locate only 1 full text articles in English which was the study of CT findings in patients with COVID-19 pneumonia after treatment with tocilizumab. It is important to note that new data is being shared regularly and so far, it consists mostly of pre-prints, case reports, small case series.

Conclusion. After analyzing the available literature, it can be concluded that the majority of authors confirm the positive effect associated with taking tocilizumab, as evidenced by a very rapid improvement in the condition of patients, however, the CT-findings often does not correlate with the clinical course of the disease and does not always show improvement in lung tissue, which should not be regarded as negative dynamics, but as a natural regression of pathological changes in lung tissue.
A COLONIZAÇÃO DA SUSTENTABILIDADE: ANÁLISE DO DISCURSO DE PEÇAS PUBLICITÁRIAS DA NATURA COSMÉTICOS
Authors: Lima Andreina Del Carmen Camero de , Saltarelli Eliza Pinto Narciso , Silva Sabrina Soares da
Published: June 2020

O conceito de sustentabilidade ganhou destaque no ambiente corporativo nos últimos anos, o que não significa necessariamente que as empresas assumam todos os seus fundamentos. O discurso de sustentabilidade, sendo cooptado pelo capitalismo, torna-se uma ferramenta de marketing. A cooptação de pensamentos alternativos pelo capitalismo, como a sustentabilidade, é mantida pela colonialidade, por meio de discursos hegemônicos que reproduzem e reforçam estruturas institucionais, políticas, econômicas, culturais e de poder. Nesse contexto, este trabalho tem como objetivo analisar o discurso de sustentabilidade em peças publicitárias da Natura Cosméticos a partir das quatro dimensões da colonialidade. As análises evidenciam que os enunciados pretendem destacar características e valores, de modo a persuadir o consumidor a comprar e utilizar os produtos da marca. Ocorre o silenciamento de alguns aspectos, tais como a exploração da natureza, a mercantilização de recursos naturais, os impactos ambientais do extrativismo, e as exigências de padrões de beleza, os quais podem ser relacionados às quatro dimensões da colonialidade.

The impact of the environment on economic growth: Evidence from China
Authors: Chang Chi , Zaernyuk V.M.
Published: June 2020

Subject. China's industrial sectors are important vehicles that made China the global leader of GDP and economic growth. However, China managed to reach such results sacrificing its environment. The study discusses the coordination of actions spurring the economic growth and environmental protection in order to avoid such sacrifices for the sake of the national economic development.
Objectives. We examine the mechanism of bilateral effects on the economic growth of China's industries and environmental protection to provide the empirical framework for the reasonable natural protection policy and environmental regulations.
Methods. Theoretical projections stem from the analysis of economic literature and empirical research on resources, environment and sustainable economic development in the existing theories of economic growth.
Results. Having analyzed how the environmental pollution and the industrial economic growth of China correlated, we found that a set of various environmental pollution indicators strongly differed from the empirical findings of the study. Therefore, it is still not found how the economic growth of China influenced the environmental pollution.
Conclusions and Relevance. The improvement of the environmental quality is not an unavoidable endogenous result of the economic growth. If the Chinese industrial sectors continues growing extensively, the environment will grow even more polluted. It is necessary to determine a reasonable environmental protection policy to combine it with economic growth, and tighten the environmental regulations.

Force majeure events as a factor encouraging the extensive distance employment at enterprises
Authors: Degtyarev A.V.
Published: June 2020

Subject. This article discusses the issues related to the distance employment of workers. Objectives. The article aims to highlight the issue of business transition to a distance operation option during force majeure events in the world economy. Methods. For the study, I used a statistical analysis. Results. The article offers certain recommendations to extend distance employment and presents two models for its development in the post-crisis environment. Conclusions. A widespread model of social and labor relations on the principle of distance-based cooperation and communication can be used extensively both in force majeure circumstances and during the normal functioning of economic systems. The proposed model of spatial allocation of economic resources would help maintain the resilience of enterprises to force majeure. However, this would involve changes in the behavioral patterns of workers.
INVESTIGATING STUDENT EXPERIENCES OF ENGINEERING TECHNOLOGY TO ENGINEERING TRANSFER IN ONTARIO
Authors: Smith Hannah , Frank Brian
Published: June 2020

The Ontario Council on Articulation and Transfer (ONCAT) Engineering Pathways Project aims to develop a large-scale network for transfer between engineering technology and engineering programs, enabling a streamlined transfer experience across multiple Ontario institutions. When developing a program of this nature, the lived experiences of students who have completed such a transition must be investigated. Eight interviews were completed with students and graduates of Ontario engineering technology to engineering transfer programs, with the intent to understand a) rationale for student transfer, b) experiences while studying, and c) experiences or plans post-graduation. A phenomenological methodology was used for analysis by inductive coding. Major results include the necessity of program accreditation for student enrollment, the benefits of short and rigorous bridging programs, and the marked lack of social and academic support students experienced during their transfer pathways. This research has been used to inform the development of the pilot phase of an Ontario-wide engineering transfer program.
THE EDUCATIONAL TRAJECTORY OF HIGH SCHOOL STUDENTS TO ENGINEERING PROGRAMS AT A COMPREHENSIVE CANADIAN UNIVERSITY
Authors: Davies Scott , Liu Qin , Evans Greg
Published: June 2020

This paper reports an analysis of an integrated data set that longitudinally tracked over 14,000 students from Canada’s largest school board (the Toronto District School Board [TDSB]) into Canada’s largest university (the University of Toronto [UofT]). Our analysis showed that when controlling for high school academic records and other student demographics, immigrant students from TDSB were more likely to pursue engineering than other fields of study; math ability was a strong predictor for the TDSB-UofT Engineering pathway; and while engineering students had better academic outcomes than other students, they had lower CGPAs than would be predicted by their academic performance in high school. These findings reveal three characteristics of UofT Engineering: its selectivity and rigor, transnational character of its student population, and complex student diversity. The study also suggests UofT Engineering look into its grading practices.
ORIENTAÇÃO DOCENTE E MODELOS TEÓRICOS DE ORIENTAÇÃO COM FOCO NO TCC DE PEDAGOGOS(AS) EM FORMAÇÃO INICIAL
Authors: Silva Claudionor Reanto da
Published: June 2020

As produções no campo da educação, sobre a orientação científica docente do Trabalho de Conclusão de Curso (TCC) vem aumentando consideravelmente e se concentram nas áreas da Educação à Distância e Educação em Ciências e Matemática. Contudo, estas produções, no seu conjunto, exigem uma organização e delineamento urgentes referente ao rigor científico da produção de conhecimento; se necessita de uma epistemologia sobre a orientação docente. Na tentativa de acrescentar um item reflexivo no campo educacional, este ensaio, se debruça sobre o tema, tecendo considerações sobre a orientação docente do TCC na formação inicial de pedagogos(as), privilegiando algumas linhas conceituais e teóricas: 1) teoria da afetividade na orientação; 2) teoria motivacional. Com o uso do método bibliográfico atende-se à seguinte pergunta de pesquisa: de que forma algumas linhas conceituais vêm apontando a articulação entre orientação docente, TCC e pesquisa educacional, em cursos de pedagogia e como elas se apresentam como recursos sadios e produtivos na relação orientador(a)/orientando? Ao se apresentarem as duas linhas teóricas se propõem alternativas à orientação docente e à produção dos orientandos(as). Finaliza-se o ensaio com a reflexão sobre o que se configura um “bom” TCC e o aspecto da publicização, e, para isto, se apresenta a Teoria das Restrições como modelo de gestão da produção do TCC em cursos de pedagogia para se atingir a práxis educativa com a transformação da realidade, pela pesquisa.

Lead induced changes in biomarkers and proteome map of Chicory (Cichorium intybus L.)
Authors: Malik Bisma , Pirzadah Tanveer Bilal
Published: June 2020

Lead (Pb) toxicity is a serious environmental problem as it affects the food production by interfering plant growth and development, thus declines the production yield. In the present research work, Cichorium intybus L. plants were subjected to different concentrations of Pb (0, 100, 200 and 300µM) upto 46days to determine the oxidative stress. The length of root and shoot, accumulation of biomass were estimated along with the changes in biomarkers (H2O2 and TBARS). Further proteomic analysis of chicory leaves (46days old) at 300µM Pb concentration was done to identify the proteins of interest. The root growth increased significantly in a concentration-dependent manner however; shoot growth, biomass accumulation declined significantly with Pb stress compared to control. Changes in biomarkers (H2O2 and TBARS) content elevated with the increment in the concentration of metal treatment but exhibited a gradual decline at 300µM Pb treatment.. Proteomics data of 46days old chicory plants under 300 µM Pb stress analyzed by PDQuest software detected approximately 168 protein spots on each gel and 81 spots were differentially expressed in which 16 were up-regulated and 13 were down-regulated. The present study suggested that chicory possess a strong antioxidative defense system to combat Pb stress and thus could be explored for cultivation in Pb contaminated soils.

Published: June 2020

Aim.To demonstrate an interesting clinical case of treating a patient with intradermal melanoma metastases.

Materials and methods.A patient with intradermal melanoma metastases was given a combined treatment including photodynamic therapy (PDT) and immunotherapy (intradermal administration of an immunological preparation into metastatic foci).

Results.A clinical case of a patient with a locoregional recurrence of skin melanoma (SM) of the left lower leg was described. Given the prevalence of the pathological substrate and the presence of concomitant pathologies, two treatment methods were selected – PDT and intradermal administration of interferon into metastatic foci. These methods provided both the local and systemic effect. As a result, the stabilisation of the tumour process was achieved.

Conclusion.Combined treatment of locoregional recurrences of skin melanoma using PDT and intrametastatic injections of immunopreparations can be used as an alternative to surgical intervention in somatically weakened patients with a large area of intradermal metastases, which will allow the tumour process to be stabilised. In cases where the area of locoregional intradermal recurrences in somatically compensated patients does not permit surgical treatment, the proposed technique may be the only possible treatment method.
