Λ-cyhalothrin causes oxidative stress accompanied by reduced glutathione alteration and modulation of regulatory protein p53 expression in the fish brain
Authors: Gasso V. Y. , Nedzvetsky V. S. , Novitskyi R. O. , Yermolenko S. V.
Published: April 2022

The synthetic pyrethroid of systemic insecticidal and acaricidal action, λ-cyhalothrin, is characterized by typical axonal excitotoxicity. Currently, it is widely used in agriculture worldwide. In fish, it negatively affects the functional characteristics of the nervous system, causes motorial paralysis, and increases mortality. The concentrations of λ-cyhalothrin for the experiment were determined at a rate of 5% and 10% of LC50, which are 271 ng/L and 542 ng/L, respectively. Λ-cyhalothrin causes oxidative damage in the brain cells of the rainbow trout and, probably, irreversible disturbances in brain cells. The content of reduced glutathione in the fish brain treated by low doses of λ-cyhalothrin was significantly lower than in the control fish. It may indicate the breakdown of this part of antioxidant protection. One of the universal and multifunctional regulatory proteins, which plays a vital role in most cell types is the p53 protein that supports cell viability through a wide range of signalling pathways. Changes in the p53 protein expression are determined in fish of all experimental groups. Moreover, less significant suppression of its expression is found in fish that have been treated by a dose of 5% LC for 28 days. Unlike the 5% LC50, the dose of 10% LC50 induces a critical decrease in the p53 protein content after both 4 and 28 days of insecticide exposure. Detected changes in the reduced glutathione content and p53 protein expression in the fish brain are associated with the oxidative stress generation caused by low sublethal doses of λ-cyhalothrin. A significant decrease in the p53 protein content in the fish brain under the impact of the low doses of the synthetic pyrethroid can indicate irreversible disturbance of this protein functioning. The inhibition of protein p53 expression may be an adequate biomarker of the nervous cell adaptation to the toxic effect of synthetic pyrethroids in the fish brain.
NORMS OF LAW GOVERNING THE ORGANIZATION AND IMPLEMENTATION OF ENFORCEMENT OF DECISIONS IN UKRAINE, IN THE STRUCTURE OF THE LEGAL SYSTEM OF UKRAINE

Published: April 2022

In the scientific article the approaches of scientists-lawyers to detecting the place of legal norms, which regulate the organization and functioning compulsory execution of decisions in Ukraine, on the structure of Ukrainian law system. Analytics is made regarding approaches the object of legal regulation in the sphere of organization and functioning compulsory execution of decisions in Ukraine, and the method. In the article is stated, that relations, that take place during organization and functioning compulsory execution of decisions, are very different on their subjects, composition, the scope of regulation inside the organization and functioning compulsory execution of decisions is characterized as complex. The article contains the summary about that fact, that in the sphere of organization and functioning compulsory execution of decisions coercion is used widely. But authorized coercion is not the single or basic method of regulation relations in the sphere of organization and functioning compulsory execution of decisions. Dispositive method of legal regulation is also widely represented in the sphere of organization and functioning compulsory execution of decisions. During the scientific exploration, made inside this scientific article, there has been stated, that legal regulation of relations, connected with organization and functioning compulsory execution of decisions, is grounded on imperative and dispositive cornerstones. As an examples can be demonstrated the right of the person, mentioned as a creditor in an executive document, to file executive document to execution, the right of debtor to offer kinds of properties of objects, he / she wants to be under enforcement primarily. In the scientific article is summarized, that legal norms, which regulate the organization and functioning compulsory execution of decisions in Ukraine form complex branch of domestic law system. Its complexity connected with complexity of object and method of legal regulation within this branch of law. The author of article offers to name this branch of law as “Executive law of Ukraine”.
LEGAL PROTECTION OF THE CONSTITUTIONAL RIGHT TO HOUSING
Authors: Chaikovskyi O. I.
Published: April 2022

Human rights as a phenomenon are, undoubtedly, the most important achievement of the modern era and the key element of civilizational development of global community; however, the range of duties that correspond to human rights must be taken into account as well. One of the major subjects in this system is the state, which bears the highest responsibility for protecting constitutional rights of its citizens. The “constitutional state” category used to characterize states with a sophisticated legal system is simultaneously distinguishable for high level of economic development, broad dissemination of democratic ideals and the priority of universal human values. However, this system is built on clearly defined legal priorities. The right to remedy is the measure and the guarantor of democratic society. With the proclamation of Ukraine as an independent state, the right of everyone to legal remedy became one of the fundamental, constitutionally guaranteed human rights. The human and citizen right to legal remedy belongs to the category of civil rights, and moreover, it contains a legal guarantee against abuse of power by particular persons, as well as by the government. Also, Article 13 of the Convention for the Protection of Human Rights and Fundamental Freedoms provides for the right for an effective legal remedy. Embodied in the constitutions of the majority of developed states, it occupies a prominent place in the structure of the legal-constitutional status of a person and represents an indispensable factor. The right to justice is reflected in the fundamental principles of the judiciary. Therefore, this right consists of the following elements: accessibility of justice; the right to appeal and cassation appeal of court judgments; independence and impartiality of courts; equality of all participants of a judicial proceeding before law and court; the right to remedy; publicity of court trials; trial of the case in the shortest possible time provided by law. At the same time, protection of the right to housing necessitates fast resolution of disputable legal issues in certain cases, which court trials sometimes cannot guarantee.
DOCTRINAL ASPECTS OF OPTIMIZATION OF ADMINISTRATIVE PROCEEDINGS OF UKRAINE
Authors: Zvirko O. Ye. , Osipova O. O.
Published: April 2022

The article is dedicated to the problems of optimization of administrative court system of Ukraine in connection with the ongoing reform of the courts. The available arguments for and against reforming the acting model of administrative justice of Ukraine are discussed. It has been clarified that the system of administrative courts in force has been specially approved for the adoption of Ukrainian society. The results of the statistical analysis show how it can successfully cope with deliveries to its arrogance. Indicate that you must reinsert the court system and recapture the administrative courts with the common courts. At the same time, with healthy administrative conviction, there are a few significant problems, among them we can call access to administrative justice and delimitation of administrative court jurisdiction from commercial and common courts jurisdictions. A closer look at the problems that need to be solved will require a farther and more thorough amendments to optimize the administrative courts activity. It has been concluded that the model of administrative justice in Ukraine since 2005 in the form of a separate subsystem of administrative courts of both the first and second links fully meets European standards and ensures the implementation of the rule of law, protection of rights and legitimate interests of individuals and legal entities, judicial control over legality and decisions of public authorities and their officials. There are no good grounds for its change (merger with courts of civil and criminal jurisdiction). Such reform will do more harm than good, negatively affect the quality of justice, the professional level of the judiciary. Prospects for further reform of administrative proceedings in Ukraine are in the area of introduction of modern mediation procedures, electronic proceedings, improvement of control over the legality of court decisions by higher courts (especially the Supreme Court of Ukraine), optimization of the burden on judges by establishing rational norms of their activity, depending on the number of cases received by the courts, the development and implementation of more effective mechanisms for the selection, training, retraining and accountability of judges.

Luego, se mencionan las divinidades raptoras y los psicopompos que intervienen en el paso de las almas al inframundo y, posteriormente, se detallan los ejemplos literarios antes mencionados con el fin de aplicar estos conceptos. Finalmente, mediante una comparación de estas ceremonias fúnebres y su contexto, se exponen los aspectos que definen la importancia de estas prácticas en el campo religioso y social.
Zeyer’s Epicism and Lyricism
Authors: Schacherl Martin
Published: April 2022

This paper aims to explore the literary creations of the Czech poet Julius Zeyer (1841–1901) within the complexity of his poetic works, except dramas. The poet, prosaist, and dramatist Julius Zeyer ranks among the classic Czech authors active in the second half of the 19th century. Literary historians traditionally link him with the Lumír generation but he is often grouped also with the New Romantics contributing to periodicals Ruch, Lumír, and Květy, or, possibly, with the ‘sensitives’ of the 19th-century European culture.

His works comprise texts of indisputable, time-honoured value, beside the texts on the verge of conventional fiction. Quantitatively, the literary production of Julius Zeyer comprises more than two thirds of epic works; almost two fifths are dramas; only a few of them are (purely) lyrical poems representing just a fraction of his comprehensive output. The proportions of the explored poetry and prose also feature two-third ratio in favour of prose against (in Zeyer, mostly epic) poetry.

The starting point of our search for specific features of his authorial style was the accentuation of Zeyer’s “epicism” and “lyricism” in references, i.e. throughout the overall reception of the poet’s texts, regardless of literary genres, often coexisting in contradictory meanings. Specifically, this study aims at the identification and linguistic analysis of selected devices to convey epic and lyric aspects in Zeyer’s epic poetry and prose.

Despite the dominant representation of epics and prose, Zeyer’s style shows distinctly lyrical features, even within the extent of his production as a whole. The lyrical nature of his epic works is enhanced by his exclusively visual imagery, purposely different from common speech, with stylistically marked bookish and archaic elements, bearing the marks of literary art nouveau.

In the middle and final stages of the poet’s creative career, his lyricism is enhanced by the changing rhythm of his narrative accentuated by the receding textual dramatization; by a greater share of non-narrative segments in the story; and through the tension ensuing from the contrasts between subjectivity / objectivity; between personification / impersonality; or between outer / inner perspective of the narrative, based on the linguistic form of concrete fictional texts and on the concrete perspective in which the story is actually mediated. Displayed in all of his literary works, lyricism is a characteristic and permanent feature of Julius Zeyer’s authorial style.

Authors: Vlasenko L. O. , Lutska N. M. , Zaiets N. A. , Shyshak A. V. , Savchuk O. V.
Published: April 2022

Context. Modern intelligent systems of failure identification of control equipment and devices in food industry are based on a complexation of approaches implemented on various methods and algorithms. The feature of such systems is that within them operates a large amount of heterogeneous data and knowledge that are difficult to combine. The use of ontologies of different levels in the system development process solves this problem.

Objective. Domain ontology development for equipment condition monitoring system as a basis for designing intelligent decision support system with ontology knowledge base.

Methods. There are different ontology development approaches. They may differ in the quantity of levels and types of ontologies or be a combination of subject and problem domains ontologies depending on the complexity of the problem and the chosen ontology development method. This paper represents two levels of the three-level ontology being developed for intelligent condition monitoring system of control equipment and devices. The upper level is represented by top-level ontology Basic Formal Ontology (BFO) which provides systematization of the meta-level, including temporal part. International standards and technical reports such as IEC 62890, ISO 55000, ISA 95, ISA 106, IEC 62264, ISO 10303-242: 2020 are considered in the development process of the second ontology level – Domain ontology.

Results. The article provides Domain ontology for equipment condition monitoring system in food industry. The developed Domain ontology systematizes, structures engineering knowledge and uses BFO which provides a set of basic elements at the metalevel. They set the values of the following entities: type of production, methods of failure identification, causes, failures, events, equipment, etc. The developed Domain ontology has semantic cross-links. A fragment of the Domain ontology relationships for the “Control equipment” subclass of “Equipment” class is also presented in the paper.

Conclusions. The developed ontology can be used to analyze the knowledge base on the causes, locations and types of failures and their identification methods. The developed ontology is a basis for application ontology development.

Authors: Bodyanskiy Ye. V. , Pliss I. P. , Shafronenko A. Yu.
Published: April 2022

Context. The problem of clustering (classification without a teacher) is often occures when processing data arrays of various natures, which is quite an interesting and integral part of artificial intelligence. To solve this problem, there are many known methods and algorithms based on the principles of the distribution density of observations in the analyzed data. However, these methods are rather complicated in software implementation and are not without drawbacks, namely: the problem of determining significant clusters in datasets of different densities, multiepoch self-learning, getting stuck in local extrema of goal functions, etc. It should be noted that the methods based on the analysis of the peaks of the data distribution density are clear in nature, therefore, to expand the capabilities of these methods, it is advisable to introduce their fuzzy modification.
Objective. The aim of the work is to introduce fast fuzzy data clustering using density peaks distribution of the datasets, that can find the prototypes (centroids) of clusters that overlapping regardless of the amount of incoming data.
Method. The problem of fuzzy clustering data arrays based on a hybrid method that based on the simultaneous use of a credibilistic approach to fuzzy clustering and an algorithm for finding the types of distribution density of the initial data is proposed. A feature of the proposed method is computational simplicity and high speed, due to the fact that the entire array is processed only once, that is, eliminates the need for multi-era self-learning, implemented in traditional fuzzy clustering algorithms.
Results. A feature of the proposed method of fast fuzzy credibilistic clustering using of density peaks distribution is characterized by computational simplicity and high speed due to the fact that the entire array is processed only once, that is, the need for multiepoch self-learning is eliminated, which is implemented in traditional fuzzy clustering algorithms. The results of the computational experiment confirm the effectiveness of the proposed approach in clustering problems under conditions in the case when the clusters are ovelap.
Conclusions. The experimental results allow us to recommend the developed method for solving the problems of automatic clustering and data classification, as quickly as possible to find the centroids of clusters. The proposed method of fast fuzzy credibilistic clustering using of density peaks distribution of dataset is intended for use in computational intelligence systems, neuro-fuzzy systems, in training artificial neural networks and in clustering problems.

OBTAINING AND CHARACTERISTICS OF MANNAN-PEPTIDE NANOHYBRID
Authors: Cherno N. , Naumenko K. , Gural L.
Published: April 2022

Bioactive peptides belong to a new generation of biologically active regulators with a wide range of important physiological effects. This determines the prospects for their use in functional foods as dietary supplements and medicine. The main source of such bioactive peptides is cow's milk. It contains proteins, which include 80% caseins. Like other bioactive compounds, they are exposed to unwanted changes in technological processes and during transit along the gastrointestinal tract. In order to improve their stability and increase bioavailability, conjugates obtained by the Maillard reaction have recently been used. Currently, it is positioned as a promising way to prevent the destructive impact of external factors. This article highlights the results of studies designed to determine the feasibility of casein fragmentation with papain to obtain bioactive peptides and the subsequent creation on their basis of a nanohybrid with a mannan component by the Maillard reaction. Enzymatic hydrolysis of sodium caseinate with papain was carried out with varying the duration of the hydrolysis process (30, 60, 120, 180, 240 min). The yield of protein proteolysis products depending on the duration of the process ranged from 77.8% to 83.9%.Enzymatic hydrolysis of sodium caseinate contributed to a significant increase in the products of its fragmentation mass fraction of amine Nitrogen – from 4561.4 to 5687.5 mg/100 g (4.6–5.7%), which is 3.5–4.4 times more than the content of free amino groups in the original sodium caseinate. Among them, almost 1/2 arebioactive peptidescontaining up to 20 amino acid residues.The mannan-peptide nanohybrid was incubated with biopeptides with modified coffee mannan, which had the ability to dissolve in water.The reaction mixture was exposed to 60 oC for 6 h. The yield of lyophilized product was 38.1%, the mass fraction of mannan reached 10.6-10.9%, and peptides, respectively, – 89.1–89.4%. The protective effect of the polysaccharide component against the peptide component was evaluated in vitro in a pepsin-trypsin system. It was found that the stability of peptides in the nanohybrid is much higher than in the original hydrolyzate. The use of the created nanohybrid is possible both to obtain protective shells of labile biologically active substances and to increase the bioavailability of peptides when they are included in dietary supplements and functional foods.
EVALUATION OF THE AVERAGE CONSUMPTION OF FOOD PRODUCTS AND ITS NUTRITIONAL VALUE IN POLAND
Authors: Grądzki D. , Glibowski P. , Glibowska J.
Published: April 2022

Balanced nutrition is the foundation of good health. Inadequate intake of the main nutrients leads to many diseases. Assessing the consumption of these nutrients is critical in taking action to improve the health of the population. The aim of this study was to analyse the average consumption of food products and its nutritional value in the Polish population. The nutritional assessment of the main nutrients in an average Pole’s diet was carried out by means of the Dieta 6D program. The data concerning the consumption of specific food products was taken from the Polish Central Statistical Office, Institute of Agricultural and Food Economics and many branch reports. Among different groups of food products village bread, full-fat milk,  milk,  chicken breast meat, sandwich ham, tomatoes,  apples,  rapeseed oil, water and beer were the most consumed in the group of bread, milk beverages, meat, processed meat, vegetables, fruits, plant oils, non-alcoholic and alcoholic beverages, respectively. The Polish diet provides a sufficient amount of the main nutrients – protein, fat, carbohydrates (14.2, 29.8, 49.1 % energy of the diet, respectively), but there are some deficiencies (fiber – 73% of the recommended intake), and an excessive supply of other ingredients (energy in women – 130%, proteins in men and women, 140% and 167%, respectively, sugar – 19.5% energy of the diet, saturated fatty acids – 10.8% energy of the diet). The average trans fatty acids intake per day is 0.99 g (0.38 % energy of the diet). Summing up, the percentage of protein, fat and carbohydrates in the diet of an average Pole meets the standards recommended by European Food Safety Authority. The diet provides an insufficient amount of fiber. The consumption of sugar, calories in both sexes, saturated fatty acids is too high. Trans fat consumption has decreased when compared to previous reports.
STUDY OF AROMATIC COMPONENTS IN THE COURSE OF INITIATING ENZYMATIC REACTIONS IN THE EDIBLE MUSHROOM PLEUROTUS OSTREATUS
Authors: Dubova H. , Dotsenko N. , Mykchaylova О. , Poyedinok N.
Published: April 2022

Various branches of the food and medical industries widely use mushrooms, that is why their aromatic characteristics are quite important. This paper presents a comparative analysis of the aromatic and fatty acid composition of the mycelium of the edible oyster mushroom (Pleurotus ostreatus (Jacq.) P. Kumm., strain K-17) cultured on a glucose-peptone-yeast growth medium with wheat bran added. The quantitative and qualitative composition of the aromas has shown that wheat bran components affect the aroma-forming reactions during the growth of the mycelium of P. ostreatus. It has been established that the introduction of wheat bran increases the content of 1-octen-3-ol, the main fungal aromatic component. In the culture liquid, 1-octen-3-ol increases by 1.4 times, as compared with classic samples cultured on a growth medium without wheat bran. Also, in the mycelium cultured on a wheat bran-containing growth medium, the total quantity of identified aromatic components increases by 1.7 times. In this mycelium, the two main components of the mushroom’s aroma are formed: 1-octen-3-ol and hexanal. In other samples, these important components are absent. The results of this study confirm that the formation of the two main fungal aromatic components, 1‑octen-3-ol and hexanal, involves polyunsaturated fatty acids, namely linoleic acid. Its content decreased in parallel with the accumulation of aromatic components throughout culturing in the wheat bran-containing medium. The data obtained allow establishing how initiation of enzymatic oxidative reactions changes the aroma of P. ostreatus during surface culturing on a liquid medium. The research results reveal the regular patterns in the formation of aromatic components of macromycetes from lipid precursors. Addition of wheat bran to a growth medium unbalances the total content of aromatic components towards their accumulation in the mycelium. Since fruiting bodies and vegetative mycelium are similar in their biochemical composition, the results of studying the mycelium cultured on a liquid medium allow predicting how aromatic components will be formed in the fruiting bodies of oyster mushrooms.

This article refers to the legal status of the Heads of Agreement in Chile. Since these legal instruments are widely used in Chile, and they do not have specific regulations, there is the need for construing an argument for understanding their legal effects, meaning that they may fall under torts or contractual regimes. The article will conclude that, in order to determine the legal regime applicable to heads of agreement, judges will need to review whether the consent was formed.

Barium isotope cycling in the marine environment: pathways of fractionation and implications for paleoceanographic applications
Authors:   , Middleton Julien T.
Published: April 2022

Removal of particulate organic carbon (POC) from sunlit surface waters into the deep ocean represents a climatically important sink of atmospheric carbon dioxide (CO2), linking the biogeochemical cycling of POC to CO2-driven climate change. As POC is not well preserved in the sediment record, other proxies, including the chemistry of barium (Ba) in the ocean and through the sedimentary record, offer an avenue to investigate oceanic carbon export through Earth’s history. This thesis seeks to constrain the controls on the formation, cycling, and isotopic signature of the main particulate phase of marine barium, the mineral barite (BaSO4) through its inception in the water column, during deposition, and ultimately into the rock record. To that end, I characterize the depth, spatial region, and general controls on particulate Ba formation in the South Pacific Ocean through shipboard experimentation and find that particulate Ba forms mainly in the surface of the Polar Frontal Zone in the presence of large particles and microbial activity. Next, I characterize the effect of ion exchange on BaSO4, a process previously unstudied under marine conditions, in a laboratory setting. Ion exchange occurs rapidly between dissolved Ba and BaSO4 and imparts a characteristic net offset between the Ba isotope composition of the dissolved and solid phase, which arises through a combination of Ba isotope fractionation during both precipitation and dissolution. Finally, I investigate the role of ion exchange in marine settings using co-located pore fluids and sedimented BaSO4. Modeling constrained by data from natural samples produce results that are consistent with the laboratory study, suggesting that this mode of isotopic fractionation impacts Ba isotopes in the environment and must be accounted for when applying Ba based climate proxies.

This article uses a socio-anthropological framework to explore the stigmas around interactions with children born with congenital Zika syndrome caused by the Zika virus epidemic in two Brazilian municipalities. Semi-structured interviews were conducted with parents and other relatives. We reflected on the search for meaning when having a baby with unexpected body marks, the moral suffering, the societal ableism, the burden of care, and the need for support networks. We concluded that public policies, especially social policies (health, education, and social assistance), are essential for compensatory mechanisms, recognition, and social inclusion of these children and their families.
“Sigue siendo un sistema precario”. Barreras de acceso a abortos clínicos: la experiencia de acompañantes en tres regiones mexicanas
Authors: Veldhuis Suzanne , Sánchez-Ramírez Georgina , Darney Blair G.
Published: April 2022

El objetivo de esta investigación fue la identificación de las barreras más recurrentes de acceso a abortos en contextos clínicos (clandestinos o legales), desde la perspectiva de acompañantes, activistas feministas que acompañan a mujeres que optaron por abortos autogestionados con medicamentos. Realizamos 14 entrevistas semiestructuradas con acompañantes en tres regiones mexicanas: Baja California y Chiapas, ambos contextos restrictivos, y la Ciudad de México, donde el aborto por voluntad es legal hasta las 12 semanas. Identificamos cuatro categorías en las cuales se entretejen las vulnerabilidades sociales de las mujeres que deciden abortar, la falta de información, persistencia de estigma, y la influencia del marco legal, los fallos en la atención del aborto, incluso en las clínicas de interrupción legal de embarazo (en la Ciudad de México), y mala calidad de los servicios prestados -maltrato, objeción de conciencia y denuncia de los proveedores de salud-, y, por último, los grupos anti-derechos y sus estrategias. En las tres regiones, el acceso a abortos clínicos sigue siendo un privilegio reservado para las mujeres que cuentan con los recursos económicos, logísticos y sociales indispensables para realizarlo en esos espacios. La existencia de un programa Interrupción Legal de Embarazo en solamente una entidad denota la existencia de una desigualdad jurídica y sanitaria. Los hallazgos de este estudio sobre mujeres acompañantes de abortos aportan elementos para que el Estado mexicano mejore el acceso a abortos seguros para todas las mujeres, sobre todo ahora que la Suprema Corte de la Justicia de la Nación decretó la despenalización, y la legalización inminente en todo el país.

RESUMO: O ensino de filosofia requer uma atuação docente e discente que permite ir além da simples descrição fenomênica da realidade ou do conhecimento. Admitindo seu objetivo de desenvolver a crítica como fundamento do pensamento humano, é necessário avançar para além de uma reflexão simplória acerca dos questionamentos que rondam nossa realidade no sentido de possibilitar que a filosofia, alicerçada no exercício da reflexão criteriosa, possa contribuir para o desvelamento da totalidade do real. Nesse sentido, este trabalho tem por objetivo apresentar a organização e a aplicação de uma Sequência Didática intitulada “Pensar a constelação da ciência: uma Sequência Didática”, no intuito de apontar uma estratégia de ensino que oportunize aos docentes uma forma de ensinar filosofia para além da perspectiva descritiva do conhecimento. Optou-se por organizar a Sequência Didática tendo como base teórica as concepções de formação integrada na Educação Profissional e Tecnológica (EPT), em diálogo com a construção do conhecimento por constelação (ADORNO, 2009). A Sequência Didática buscou desenvolver a reflexão e a construção de novos conhecimentos por constelação com o objetivo de possibilitar, durante sua aplicação, momentos e espaços de atitude reflexiva e crítica, a produção de conhecimentos, o desenvolvimento da autonomia intelectual e a compreensão da realidade social. O objetivo deste trabalho foi atingido, uma vez que o desenvolvimento das atividades nos permitiu destacar e desenvolver termos importantes, tais como: ciência, senso comum, método científico, comunidade científica, responsabilidade social e valores cognitivos, éticos e políticos.
AÇÕES DE PROFESSORES E O MOVIMENTO DE MUDANÇAS EM ATIVIDADE DE FORMAÇÃO CONTÍNUA

Published: April 2022

RESUMO: A formação contínua de professores que ensinam Matemática nos primeiros anos do ensino fundamental é tema deste artigo, que apresenta resultados de uma pesquisa de doutorado cujo objetivo foi investigar a atividade docente no processo de formação contínua buscando, a partir de seu modo de organização, compreender como as mudanças no conteúdo e na forma podem ser produzidas. Para tal, foi desenvolvido um movimento formativo com professores e coordenadores do 1º ao 5º ano de uma escola municipal de tempo integral de um sistema escolar brasileiro. Discussões relacionadas ao conhecimento matemático, análises das práticas docentes e socialização de experiências foram desenvolvidas neste processo. As ações formativas e de pesquisa, cujo processo estruturou-se sobre a base do método cunhado por Vigotski, foram respaldadas pelos princípios teórico-metodológicos da teoria histórico-cultural, com foco na teoria da atividade. Resultados da pesquisa apontam que quando o conteúdo da atividade de formação docente toma como base o conhecimento científico e as ações coletivas de trabalho são priorizadas, novos significados quanto à organização do ensino da Matemática e de seus objetos de ensino são desenvolvidos. Impulsionadas pelo desenvolvimento do pensamento teórico, mudanças no conteúdo e, consequentemente, no caminhar da atividade docente, se manifestam. Essas mudanças não se produzem de modo linear e/ou isolado, pois sofrem impacto das formas de organização escolar gestadas nas relações capitalistas em que se materializam as condições concretas de trabalho do professor, as quais se contrapõem ao movimento de mudança do conteúdo e forma da atividade docente.

Abstract: The subject of this article is the continuous education of the elementary school Mathematics teachers. It shows the result of a Ph.D. research conducted to investigate how changes in content and form can be produced in teaching activity in the context of a continuous education seeking process. For this purpose, a formative movement was promoted to teachers and coordinators from the 1st to the 5th grade of a full-time municipal school from the Brazilian education system. In this movement, discussions related to mathematical knowledge, analysis of teaching practices, and experience sharing were conducted. The formative and research actions were supported by the theoretical-methodological principles of historical-cultural theory, focusing on the theory of activity and based on the method coined by Vygotsky. Results suggested that when the content of the teaching activity is based on scientific knowledge and collective work actions are prioritized, new meanings regarding the organization of mathematics teaching and its teaching objects are developed. Driven by the development of theoretical thinking, changes in content and, consequently, in the course of teaching activity, are manifested. These changes are not produced in a linear and/or isolated way, because they are impacted by the forms of school organization in capitalist relations in which the concrete working conditions of the teacher materialize, which are opposed to the movement of change in the content and form of the teaching activity.
INSTITUCIONALIZAÇÃO DA EDUCAÇÃO A DISTÂNCIA PÚBLICA ENQUANTO FENÔMENO ESSENCIALMENTE DIALÉTICO

Published: April 2022

RESUMO: O objetivo deste artigo é examinar as relações de causa e efeito no processo de incorporação orgânica da Educação a Distância (EaD) nas universidades públicas. Para tanto, propomos o conceito de dialética para explicar a institucionalização da modalidade. No que se refere à metodologia, a partir da triangulação metodológica utilizamos diferentes instrumentos, estratégias e fontes de coleta, a saber: análise documental; grupos focais virtuais; entrevistas semiestruturadas; técnica Delphi; e questionário virtual. Os dados foram analisados mediante as abordagens qualitativa e quantitativa, sem perder de vista a nossa matriz epistemológica concernente à sociologia compreensiva de Max Weber. Esta diz respeito à apreensão das universidades enquanto aglomerados de sujeitos que atribuem sentido subjetivo à sua ação socialmente orientada. Com o estudo, chegamos ao entendimento de que a institucionalização da EaD é um fenômeno essencialmente dialético, porque está enredado em constantes embates movidos pelas contradições imanentes. Enquanto persistem as visões dicotômicas, sobretudo por meio do modelo instituído pelo Sistema Universidade Aberta do Brasil (UAB), tem-se importantes percalços na incorporação orgânica da modalidade. Assim sendo, consideramos que a superação dessa política pública de caráter emergencial tende a culminar no processo maior de síntese, em que EaD e educação presencial se tornam justapostas. Chega-se à educação híbrida, uma vez que os qualificativos “presencial” e “a distância” se tornam secundários, dando-se maior enfoque ao processo educacional.
INSTITUTIONALIZATION OF PUBLIC DISTANCE EDUCATION AS ESSENTIALLY DIALETIC PHENOMENON
Authors: VELOSO BRAIAN , MILL DANIEL
Published: April 2022

ABSTRACT: The purpose of this article is to examine the relations of cause and effect in the process of organic incorporation of distance education in public universities. Therefore, it is proposed the concept of dialectics to explain the institutionalization of the modality. With regard to the methodology, from the methodological triangulation different instruments, strategies and sources of data were used, namely: documentary analysis; virtual focus groups; semi-structured interviews; Delphi technique; and virtual questionnaire. The data were analyzed using qualitative and quantitative approaches, without losing sight of our epistemological matrix concerning Max Weber’s comprehensive sociology, which concerns the apprehension of universities as clusters of subjects who attribute a subjective sense to their socially oriented action. With the study, it was understood that the institutionalization of distance education is an essentially dialectical phenomenon, because it is enmeshed in constant institutional conflicts driven by immanent contradictions. While dichotomous views persist, especially through the model established by the Open University System of Brazil (UAB - Sistema Universidade Aberta do Brasil), there are important obstacles in the organic incorporation of the modality. Therefore, it is considered that the overcoming of this public policy of an emergency nature tends to culminate in the greater synthesis process, in which distance education and classroom education become juxtaposed. Hybrid education is achieved, since the qualifications “face-to-face” and “distance” become secondary, giving greater focus to the educational process.
PROJETO DE VIDA E IDENTIDADE: ARTICULAÇÕES E IMPLICAÇÕES PARA A EDUCAÇÃO
Authors: SILVA MARCO ANTONIO MORGADO DA , DANZA HANNA CEBEL
Published: April 2022

RESUMO: A relação entre identidade e projeto de vida tem sido assinalada tanto pelos marcos legais que definem o projeto de vida como eixo da educação básica no Brasil quanto pelos estudos sobre projeto de vida publicados no país e no exterior. Não obstante, documentos como a Base Nacional Comum Curricular e o Novo Ensino Médio não aportam fundamentos teóricos que possibilitem aos profissionais da educação conhecer como identidade e projeto de vida se constroem e se articulam, assim como compreender suas implicações pedagógicas. No plano acadêmico, por sua vez, a relação entre identidade e projeto de vida tem sido pouco tematizada de maneira explícita e sistemática. O presente artigo, de caráter teórico e inscrito na interface entre os campos da educação e da psicologia, explora as articulações entre estudos sobre projeto de vida e sobre identidade no que diz respeito à constituição, ao desenvolvimento e ao funcionamento desses construtos, bem como discute suas implicações para a educação. Para tanto, delimita o conceito de projeto de vida à perspectiva fundada pelo Centro de Estudos sobre a Adolescência da Universidade de Stanford (Estados Unidos), coordenado por William Damon, e circunscreve os processos de construção e funcionamento da identidade às abordagens de estados da identidade, identidade narrativa e identidade moral, cuja matriz comum é a obra de Erik Erikson.
SUSTENTABILIDADE COMO PRÁXIS PEDAGÓGICA PARA A TRANSDISCIPLINARIDADE NA EDUCAÇÃO PROFISSIONAL E TECNOLÓGICA (EPT)
Authors: PEREIRA MÁRIAM TRIERVEILER
Published: April 2022

RESUMO: A ideia deste artigo surgiu de inquietações sobre a trajetória e o potencial da Educação Profissional e Tecnológica (EPT) no Brasil, em um momento crucial da história da humanidade, a Idade da Complexidade, em que ocorrem rápidas transformações no modo produtivo, com profundas implicações ambientais. Estudos mostram que, daqui a algumas décadas, o indivíduo não terá uma única profissão, serão constantes a criação e o desaparecimento de várias ocupações. Por esse motivo, há previsões de que, até 2050, deva surgir uma nova classe de indivíduos: os “inempregáveis”. Com isso, obviamente, os problemas sociais e econômicos advindos de todo esse processo provocarão problemas ambientais, que são o cerne da sustentabilidade. Tendo em vista esse cenário vindouro, desde o ano 2000, tem havido esforços mundiais para o atingimento das metas do desenvolvimento sustentável, inicialmente, com oito Objetivos do Milênio (ODM) e, posteriormente, com dezessete Objetivos de Desenvolvimento Sustentável (ODS). Levando em consideração esse contexto de transformações, o objetivo deste trabalho foi analisar as práticas de sustentabilidade como um possível caminho para o alcance da transdisciplinaridade na EPT. Para tanto, foram observados e discutidos os conceitos e as peculiaridades da EPT, da transdisciplinaridade e da sustentabilidade. Em um momento acelerado de transformações motivadas pela pandemia da Covid-19, é urgente que o projeto da EPT se modifique para acompanhar as rápidas mudanças tecnológicas e das relações econômicas, sociais, políticas e culturais. Devemos, então, aproveitar esse momento ímpar na história da humanidade para desenvolver uma reforma ampla nos conteúdos e nas metodologias da EPT.
Automation and job loss: the Brazilian case

Abstract Technological innovations are enabling machines to further replace human labor. In this context, we estimate - based on the Frey and Osborne (2017) study, which uses data from the United States of America (USA) - how many Brazilian jobs may be eliminated in one or two decades due to currently existing technologies. We add to earlier research, that included the Brazilian case, as we consider the entire employment structure - including both formal and informal sectors - in order to estimate the proportion of jobs in the country that may be substituted by machines. Our results indicate that 58.1% of Brazilian jobs may disappear over the next 10 to 20 years due to automation. Moreover, we observe that jobs in the informal sector face higher probabilities of elimination by automation when compared to the formal sector.
