Authors: Baravets Y. , Dvorak P. , Todorov F. , Ctyroky J. , Peterka P. , Honzatko P.
Published: January 2020

We present a fibre laser broadly tunable in a wavelength range from 1058 nm to 1640 nm based on a new type of metallic resonant leaky-mode diffraction grating and three fibre-pigtailed semiconductor optical amplifiers. For TM polarization in Littrow configuration, the grating has experimentally measured diffraction efficiency into the −1
st
reflected order of more than 90 % over a spectral range of 1417 nm to 1700 nm. The laser covered a spectral range of 331 nm within a tuning band of 558 nm without any adjustment of optics and its tuning range was limited by amplification bands of available semiconductor optical amplifiers.

Authors: Fu Yanping , Wu Qianchao , Yao Yong , Gan Yaping , Liu Chuyan , Yang Yanfu , Tian Jiajun , Xu Ke
Published: January 2020

A rapid and precise phase-retrieval method based on Lissajous ellipse fitting and ellipse standardization is demonstrated. It only requires two interferograms without pre-filtering, which reduces its complexity and shortens the processing time. The elliptic coefficients obtained by ellipse fitting are used for ellipse standardization. After compensating phase-shift errors by ellipse standardization, the phase distribution is extracted with high precision. It is suitable for fluctuation, noise, tilt-shift, simple and complex fringes. This method is effective for the number of fringes less than 1. The reliability of the method is verified by simulations and experiments, indicating high accuracy and less time consumption.

Published: January 2020

The dynamic sampling rate of Brillouin optical time domain analysis (BOTDA) is limited by fiber length. For breaking through this limit, a Brillouin optical time domain collider (BOTDC) is proposed and experimentally demonstrated. In this BOTDC, by employing frequency-hopping pump and probe waves, sensing information-crosstalk between adjacent pump pulses is avoided even though the pump pulse interval is shorter than the round-trip time of flight in the fiber. In the experiment, periodic mechanical vibrations with a 19.75 Hz fundamental frequency and a 39.49 Hz harmonic frequency are measured by a 10-frequency BOTDC with a sampling rate of 49 kHz which is 10 times higher than that in the BOTDA.

Authors: Yan Zhendong , Zhu Qi , Wan Mingjie , Lu Xue , Pu Xingting , Tang Chaojun , Yu Lili
Published: January 2020

We propose an ultraviolet perfect ultranarrow band absorber by coating a dielectric grating on the monolayer graphene-dielectric-metal structure. The absorber presents an ultranarrow Fano lineshape with quality (Q) factor of 70 and a nearly perfect absorption of over 99.9% in the ultraviolet region, which is ascribed to the near field coupling of the optical dissipation of graphene and guide mode resonance of the dielectric grating. Structure parameters to the influence of the performance are investigated. The structure exhibits the high optical sensitivity (S = 150 nm/RIU, S* = 48/RIU) and figure of merit (FOM = 50, FOM* = 25374) and can also be used to detect the nanoscale analyte layer of sub-nanometer thickness, suggesting great potential applications in ultra-compact efficient biosensors for a much more sensitive detection of small refractive index changes.
Comunidad de conocimiento y evolución humana

Published: January 2020

El planteamiento se edifica sobre el supuesto de que el entorno cultural es condición necesaria para la práctica de la profesión biológica de la especie humana; por este motivo defendemos que la evolución de las comunidades homininas dependió del hecho de irse progresivamente instituyendo como comunidades de conocimiento; a esto se denomina hoy “impulso cultural”. Para elaborar la argumentación, emplearemos la metodología de asociar los descubrimientos evolutivos con las exigencias filosóficas de una teoría de la ayuda necesaria para el desarrollo de la mente; trataremos de comprobar si los procesos culturales, educación, precedieron a los primeros talleres artesanos. El conocimiento disponible permite concluir que la humanización tuvo lugar en el contexto de una aproximación a la naturaleza con iniciativa socialmente compartida; en ese contexto, el impulso cultural, los llevó a enseñar y a prestar atención a los estados mentales de los otros; en este escenario pedagógico se produjo la emergencia y la evolución de habilidades cognitivas.

Background and Aim: Ovariohysterectomy (OHE) is a common procedure for sterilization of female dogs. However, knowledge of changes in pain stress, oxidative stress, and total antioxidant power status before, during, and after OHE is limited. The objective of this experiment was to study the effect of duration on pain stress, oxidative stress, and total antioxidant power status in female dogs undergoing OHE. Materials and Methods: Seven female dogs were sterilized using the OHE method. Pain scores, hematological changes, and biochemical markers were investigated during pre-operative, 3 h after starting OHE, and on days 3, 7, 10, and 14 of an experimental period. Data were analyzed using one-way analysis of variance. Results: At 3 days after OHE, pain score was higher than on days 7-14 of the experimental period; percentage of neutrophil, 3 h after starting OHE, was higher than during pre-operative and on days 3-14 of the experimental period; percentage of lymphocyte on days 10-14 was lower than during pre-operative, 3 h after starting OHE, and on days 3-7 of the experimental period; neutrophil/lymphocyte ratio, 3 h after starting OHE, was higher than during pre-operative and on days 3-14 of the experimental period; plasma malondialdehyde on day 3 was higher than during pre-operative, 3 h after starting OHE, and on days 3-14 of the experimental period; and total antioxidant power on day 14 was higher than during pre-operative, 3 h after starting OHE, and on days 3-10 of the experimental period, respectively. Conclusion: This experiment indicated that OHE caused pain stress, oxidative stress, and reduction of total antioxidant power in female dogs. Finally, female dogs needed antioxidant for 7 days after OHE.

Published: January 2020

End-stage liver disease management requiring orthotopic liver transplantation is being increasingly performed across the United States. However, some of the most common postoperative complications are bile leak and anastomotic stricture formation. These complications are successfully managed in most patients with endoscopic retrograde cholangiopancreatography (ERCP). We hereby report a case of acute parotitis, an extremely uncommon complication after ERCP. The exact etiology of this complication is not known. However, we discuss the treatment and purported mechanistic risk factors of this unusual post-ERCP adverse event.

Published: January 2020

A incidência, prevalência e morbidade da onicomicose, a tornam um problema de saúde pública evidente. O diagnóstico clínico, baseado somente nas características clínicas das lesões, tem se revelado insuficiente, levando a erros terapêuticos. O diagnóstico micológico é extremamente importante para definir a verdadeira causa da lesão e auxiliar na escolha da terapêutica adequada. Nesse sentido, acadêmicos de Farmácia da Universidade Federal do Vale do Jequitinhonha e Mucuri (UFVJM) procuraram conscientizar alunos do 9º ano do ensino fundamental das escolas públicas de Diamantina sobre as formas de contágio, sintomas, diagnóstico, tratamento e profilaxia das micoses de unha por meio de palestras e cartilha orientadora sobre o tema. Além dessa ação, exames micológicos foram realizados em amostras de raspas de unha de alunos que apresentavam sinais da presença de micose de unha, sendo diagnosticado um caso positivo e encaminhado ao médico dermatologista, o qual indicou a terapia medicamentosa apropriada. Foi realizado o acompanhamento do tratamento até a evidência de cura. A abordagem, além de cumprir seu objetivo, que é a extensão, envolveu atividade de pesquisa e de intervenção social, beneficiando todos os atuantes: escola, alunos, bolsistas, curso e universidade, enriquecendo a produção universitária e contribuindo para a qualidade de vida da população.

NUMERICAL REALIZATION OF THE ALGORITHM FOR SOLVING THE TASKS OF HYDROPHYSICS IN THE AREA WITH COMPLEX GEOMETRY
Authors: Sukhinov A. I. , Chistyakov A. E. , Litvinov V. N. , Nikitina A. V.
Published: January 2020

The work is devoted to the development and numerical implementation of an algorithm for solving the problem of modeling the process of hydrophysics, describing the transport of polluting biogenic substances in a complex shape. The velocity field of the water flow, calculated according to the hydrodynamic model of the Sea of Azov, is used in the model of transport of polluting nutrients as input data. To test the accuracy of the numerical solution of the hydrodynamic model problem, a test problem of viscous fluid flow between two coaxial semicylinders is used. To solve the interrelated problems of hydrophysics, including a model of hydrodynamic processes and a model of transport of polluting nutrients, rectangular grids are used, taking into account the “fullness” of the cells. The approximation of the problem in time is made on the basis of splitting schemes for physical processes. To assess the accuracy of the numerical solution of hydrodynamic problems, an analytical solution describing the Couette–Taylor flow is used as a reference. The simulation was carried out on a sequence of thickening computational grids with dimensions: 11×21, 21×41, 41×81 and 81×161 nodes in the cases of a smooth and stepped border. To increase the smoothness of the solution, grids were used that take into account the “fullness” of the cells. In the case of a stepwise approximation of the interface between two media, the calculation error reaches 70 % of the error solution of the problem. When using grids that take into account the “fullness” of cells, the error in the numerical solution of model problems of hydrodynamics, caused by the approximation of the boundary, does not exceed 6 % of the error solution of the problem. The example shows that the fragmentation of the grid by 8 times for each of the spatial directions does not lead to an increase in the accuracy that solutions obtained on the grids, which take into account the “fullness” of the cells, possess.
COMPUTER TECHNOLOGY OF SYNTHESIS OPTIMAL LINEAR SWITCHED SYSTEMS
Authors: Bortakovsky A. S. , Uryupin I. V.
Published: January 2020

The linear-quadratic problem of synthesis optimal control of switched systems is considered. Continuous change of state of the system is described by linear differential equations, and instantaneous discrete changes of state (switching) – linear recurrent equations. The moments of switching, and their number is not prespecified. The quality of control is characterized by a quadratic functional, which takes into account the cost of each switch. The considered problem generalizes the classical linear-quadratic problems of optimal control of continuous, discrete and continuous-discrete systems, transferring them to a new class of dynamic systems – switchable (hybrid) control systems. Together with the problem of optimal control synthesis, the problem of minimizing the number of switchings, characteristic of hybrid systems, is relevant. The peculiarity of the synthesis of optimal switchable systems is that the price function in the considered problem is not quadratic. Therefore, it is proposed to build a price function from auxiliary, so-called price moment functions, each of which is defined as the minimum value of the quality functional at fixed switching moments and is quadratic. At the same time, the optimal positional control, linear in state, depends nonlinearly on switching moments. Optimization of these moments becomes the last stage of the synthesis. The proposed computer-aided synthesis technology makes it possible to find the optimal “controlling complex”, including the number of switches, the switching moments, as well as the control of continuous and discrete movements of the system. The application of the developed technology is demonstrated on an academic example of synthesis.

Published: January 2020

Algorithms for seminatural stochastic (statistical) modeling of tracking gauges of homing systems are intended for use in models of guided missiles of information about angular errors of homing heads recorded in real conditions of use. Such information is obtained by processing the data of field experiments. Algorithms provide reproduction of signals at the output of angular measurements, which are closest to the signals observed in field experiments. To achieve the coincidence of the reproduced angular errors with errors recorded in the actual conditions of the use of guided missiles, data on the phase coordinates of the homing heads, such as expectation and dispersion of angular errors, are used. Information on angular errors is placed in a specialized two-dimensional database of angular errors. The target coordinates of the database and the angular velocity of the line of sight of the target, which are the components of the vector of signs of the phase coordinates, are used as the address coordinates of the database. An example of a comparative evaluation of three possible stochastic modeling algorithms is given. The assessment was performed using the information quality indicator in the form of a percentage of the decrease in relative conditional entropy. For the considered example, it is shown that the algorithm using the quadratic prediction of changes in the signs of phase coordinates has advantages over the algorithm for linear prediction and the algorithm for selecting the “closest” value of the signs of phase coordinates.
THE EFFICIENCY OF MONITORING THE SURFACE OF THE EARTH THROUGH THE CUMULUS CLOUDINESS LAYER
Authors: Muzhichek S. M. , Obrosov K. V. , Safonov V. A. , Lisitsyn V. M.
Published: January 2020

The effectiveness of monitoring the underlying surface (US) during its passive remote sensing in the optical wavelength range from an aircraft is estimated. It is supposed that the monitoring is carried out in the conditions of a Cumulus cloudiness which partially closes US. An on-board optical-electronic system has the ability to deviate from the vertical of a narrow field of view. By controlling the position of the field of view, the ECO forms inclined optical paths. In the presence of gaps between the Cumulus clouds under the aircraft inclined optical paths provide the possibility of optical contact with fragments of US. The key problem in assessing the effectiveness of such monitoring is to determine the probability of sighting the US through a cloud layer along inclined paths. The probability of sighting depends on such parameters as the degree of sky coverage, the angle of deflection of the line-of-sight from the vertical, and the geometric parameters of the 3D cloud shapes (horizontal extent, section height, distance between the cloud section edges). As a result of modeling, the dependences of this probability on various combinations of parameters of cumulus clouds are obtained. This allows you to determine the guaranteed probability and the bandwidth of US monitoring for various cloud parameters, altitude of the aircraft and clouds. The obtained dependences of the probability of sighting US on the angles of orientation of the field of view in conditions of cumulus clouds can be used as input data to estimate the probability of detecting objects on the US when they are accompanied during the flight.
INTELLIGENT APPROACH FOR DIAGNOSIS ELECTRICAL EQUIPMENT OF INDUSTRIAL FACILITIES
Authors: Kolodenkova A. E. , Vereshchagina S. S.
Published: January 2020

This paper is devoted to actual problem of ensuring of trouble-free functioning and a high level of fault tolerance of industrial facilities’ electrical equipment (EE) by diagnosing them during their operation. However, when diagnosing equipment, a number of challenges arise related to the following problems: a large number of monitored parameters, the presence of not only statistical information but the values of linguistic variables that are used by staff on duty, insufficient and incomplete input information. Proposed approach to diagnosing EE based on a composition of fuzzy cognitive model with a fuzzy vertices, links and fuzzy-functional cognitive model with functional links for generating intermediate information, and as well as fuzzy-production model of an upper level for taking final diagnostics decisions. The proposed approach is based on the functional model of EE diagnosing in IDEF0 notation which reflects the sequence of all necessary functions related to the diagnosing and provides the identification of the key data flows and a more comprehensive understanding of the process. The paper also provides a formulation of the fuzzy-set method that is based on the construction of functional dependencies formed in clear mapped set “the occurrence frequency of for equipment's dangerous situation”. This method’s novelty lies in the new formulation of the problem in accordance with the latest scientific achievements and its solution that was not previously considered in the well known sources of literature. The suggested method is allows to calculating the predicted values of controlled parameters of EE in case of statistic and fuzzy source data. The proposed approach to the EE diagnosis at industrial objects makes it possible to improve the accurate and complete EE diagnosis through the knowledge of the staff on duty, thereby resulting in timely repair and maintenance.
HIGH-SPEED INDUSTRIAL REAL-TIME NETWORK OF CYBERPHYSICAL SYSTEMS
Authors: Zelensky A. A.
Published: January 2020

The construction of a high-speed industrial real-time network based on FPGA (Field-Programmable Gate Array) for the control of machines and industrial robots is considered. A brief comparative analysis of the performance of the implemented Ethernet-based Protocol with industrial protocols of other leading manufacturers is made. The aim of the research and development of its own industrial automation Protocol was to reduce the dependence on third-party real-time protocols based on Ethernet for controlling robots, machines and technological equipment. In the course of the study, the requirements for the network of the motion control system of industrial equipment were analyzed. In order to synchronize different network nodes and provide short exchange cycle time, an industrial managed switch was developed, as well as a specialized hardware controller for processing Ethernet packets for end devices, presented as a IP-core. A key feature of the developed industrial network is that the data transmission in it is completely determined, and the exchange cycle time for each of the network devices can be configured individually. High efficiency and performance of implemented network devices became possible due to the use of hardware solutions based on FPGAs. All solutions described in the article as part of a modular digital system have been successfully tested in the control of machines and industrial robot. The results of field tests show that the use of FPGAs and soft processors with specialized peripheral IP-blocks can significantly reduce the tact of managing industrial equipment through the use of hardware computing structures, which indicates the promise of the proposed approach for solving industrial automation tasks.
Trabalho docente instrumentalizado na política de formação de professores no Brasil: Uma abordagem histórica e teórico-pilosófica

Published: January 2020

O texto aborda a política/gestão de formação de professores no Brasil e ancora-se nos resultados da pesquisa “Política/gestão da formação de professores na perspectiva da filosofia da práxis: tensão entre as perspectivas econômico-corporativa e ético-política”. O objetivo da investigação da qual resulta esta reflexão consistiu em explicitar – sob o ponto de vista histórico e teórico-filosófico – a instrumentalização do trabalho docente no processo de formação de professores, sem desconsiderar a existência teórico-prática da perspectiva formativa emancipadora fundamentada nos princípios ético-políticos e da filosofia da práxis. Na consecução do objetivo proposto utilizamos o referencial teórico-metodológico histórico e crítico-dialético e o projeto foi desenvolvido por meio das pesquisas bibliográfica e empírico-documental. Neste artigo, objetivamos discutir os fundamentos da política/gestão de formação dos professores brasileiros na perspectiva instrumental e sua relação com o trabalho docente. A pesquisa revelou, sob o ponto de vista histórico e teórico-filosófico, que a formação de professores no Brasil, tendencialmente, ocorreu na perspectiva instrumental, com a priorização da dimensão técnico-pedagógica em relação à político-cultural. Todavia, a instrumentalização do trabalho docente não se constitui de forma linear ou desprovida das contradições tensionadas pelas forças que vêm lutando por uma educação e formação de professores numa perspectiva substantiva, libertária e emancipadora.
Assédio moral na pós-graduação: As consequências vivenciadas por docentes e discentes de uma Universidade Estadual brasileira
Authors: Nunes Thiago Soares , Torga Eliana Marcia Martins Fittipaldi
Published: January 2020

A Pós-Graduação apresenta um contexto fértil para a ocorrência de assédio moral, pois tem, nas suas práticas, cobranças e pressões intensas, busca frequente pelo produtivismo, alta competitividade e vaidade. Por isso, as consequências desse ambiente exigente podem ser ainda mais severas, afetando a saúde, o trabalho, os estudos e a vida privada do profissional. Diante do que foi exposto, este artigo tem como objetivo identificar as consequências proporcionadas pelo assédio moral em discentes e docentes vinculados aos Programas de Pós-Graduação stricto sensu em uma Universidade Estadual Brasileira. A pesquisa foi caracterizada como abordagem mista, descritiva e estudo de caso. Os dados foram coletados por questionário on-line (126 respostas) e entrevistas (7), sendo estes tratados pela técnica de análise de conteúdo. Constatou-se que as consequências envolveram a saúde psíquica (raiva, ansiedade, baixa autoestima, depressão); saúde física (alopecia, aumento de peso, tremedeira); relacional/afetivo (afastamento/perda de amigos, crises conjugais); e trabalho/estudo (desilusão com o meio acadêmico, aumento da carga de trabalho, vontade de desistir da pós-graduação). A partir do que foi constatado nesta pesquisa, acredita-se que o tema merece atenção devido ao seu caráter destruidor, e, além disso, sugere-se, ainda, a construção de medidas efetivas de prevenção e de combate ao assédio moral.
O modelo de governança corporativa na educação superior e as repercussões no trabalho docente: Um estudo de caso
Authors: Kato Fabíola Bouth Grello , Chaves Vera Lúcia Jacob , Meguins Rosimê da Conceição
Published: January 2020

Este artigo analisa as repercussões da adoção do modelo de governança corporativa para o trabalho docente no interior de uma instituição de ensino superior do estado do Pará, organizada administrativamente como universidade e pertencente, desde 2014, ao Grupo Ser Educacional S.A. Trata-se de um estudo de caso, com análise documental além da análise de três entrevistas semiestruturadas com os professores da Universidade da Amazônia/Ser Educacional para compreender quais as mudanças trazidas para o trabalho docente, nas atividades de ensino, nas condições de trabalho e na gestão universitária a partir de sua venda para o Grupo Ser. As análises revelam que a incorporação da gestão profissional orientada pelo modelo de governança corporativa traz mudanças na cultura pedagógica, na gestão colegiada, e nas condições de trabalho. As falas demonstraram que há um comprometimento do papel político e social da educação, sobretudo, a partir da incorporação de uma política de austeridade de gestão pedagógica que hoje o mundo corporativo exige de empresas educacionais que operam neste formato, caracterizado por profunda heteronomia do trabalho do professor, pela fragmentação e controle do seu trabalho pedagógico além da pauperização e perda do reconhecimento social.
A subjetivação capitalista enquanto mecanismo de precarização do trabalho docente na educação superior
Authors: Fávero Altair Alberto , Bechi Diego
Published: January 2020

O modelo de subjetivação capitalista determina a generalização da concorrência como norma de conduta, intima os indivíduos a conceber a si mesmo e a comportar-se como uma empresa, ordena as relações sociais segundo o modelo de mercado e altera a lógica das políticas públicas. O presente ensaio visa compreender, a partir do referencial teórico de P. Dardot & C. Laval (2016a, 2016b, 2010), F. Guattari (1985, 1996), G. Alves (2011, 2008), D. Mancebo (2007, 2003), dentre outros, como se constitui a subjetividade do trabalhador docente do ensino superior, diante do atual processo de expansão hegemônica da racionalidade toyotista/neoliberal, e de que forma esse processo de subjetivação capitalística tem interferido sobre as condições de trabalho e ao modo/projeto de vida dos profissionais da educação. Trata-se de um estudo exploratório quanto aos objetivos e bibliográfico quanto aos procedimentos de cunho hermenêutico-analítico. Inicialmente, o ensaio trata das transformações na estrutura político-econômica, cultural e produtiva, inerentes à expansão do capitalismo flexível, que deram sustentação à construção de um novo modelo de “governança” e à formação de um novo sujeito produtivo (autogovernável). Em seguida, apresenta os mecanismos e movimentos utilizados pela racionalidade toyotista/neoliberal na formação de uma subjetividade produtivista e concorrencial e suas implicações sobre os ritmos e condições de trabalho; por fim, busca compreender as metamorfoses do trabalho docente, incluindo o fenômeno relativo à intensificação e à precarização de suas condições de trabalho, decorrente do processo de subjetivação capitalista.

Published: January 2020

En este trabajo describimos la situación laboral del profesorado novel, que se ha incorporado como docente a la Universidad de Cádiz en los 5 últimos años. Comparamos la situación en la que el colectivo se encontraba en 2015, momento duro en la crisis económica que junto al país sufre el sistema universitario, con la que el colectivo tiene o percibe en 2019. Se trata de un estudio cuantitativo realizado a través de un cuestionario on-line, distribuido en 2015 y 2019. Sin duda la situación económica de la Universidad condiciona el desarrollo profesional de estos trabajadores, que combinan investigación y docencia. La crisis económica que ha dificultado durante años publicar convocatorias de plazas estables para estos nuevos profesores no les permite tener una visión optimista en relación a su futuro profesional. Nuestro estudio refleja que la situación actual está generando en el profesorado un sentimiento de agotamiento emocional en el trabajo, que puede derivar de no intervenir la universidad en una mayor despersonalización o dureza con su alumnado. Debido a esta situación las Universidades se están convirtiendo en un verdadero “caldo de cultivo” para sufrir patologías asociadas al malestar docente.

O presente artigo sumariza a identificação dos conflitos envolvendo o trabalho docente nos grupos educacionais de capital aberto, com ações na bolsa de valores [B]³ e que atuam na educação superior brasileira, especialmente: Ânima, Estácio, Kroton e Ser Educacional. A construção do objeto partiu da sistematização da empiria, por meio de metodologia específica para análise de conflitos sociais. A pesquisa possibilitou coligir conflitos existentes nessas organizações de ensino e que envolvem docentes e estudantes. O levantamento foi realizado a partir de reportagens que mencionavam a ocorrência de conflitos nas organizações estudadas (2009-2018). No total foram localizadas 102 reportagens que relatavam 56 conflitos. A partir desse levantamento, foi possível identificar que os docentes atuantes nesses grupos vivenciam reformas pedagógicas que favorecem disciplinas online, superlotação nas salas de aula e demissões. Para a caracterização dos grupos educacionais a pesquisa utilizou as informações do Censo da Educação Superior, o portal eletrônico da bolsa de valores, os sites dos grupos empresariais selecionados, revistas e jornais especializados. A investigação conclui que a análise dos conflitos permite compreender mudanças advindas do controle financeiro das organizações de ensino.
Desbordadas/os: Rendición de cuentas e intensificación del trabajo en la universidad neoliberal. El caso de Chile
Authors: Sisto Vicente
Published: January 2020

En un contexto de políticas universitarias orientadas por modelos de tipo neoliberal, la Universidad ha sido fuertemente interpelada por el aumento de la rendición de cuentas y mecanismos de financiamiento basados en desempeño. Estos mecanismos interpelan el trabajo de la Universidad y a sus trabajadores: los y las académicas. Esta investigación explora, desde la posición de las y los académicos cómo las políticas de rendición de cuentas implementadas desde el nivel central, son desplegadas en el espacio local interpelando al trabajo académico y a sus trabajadoras y trabajadores. Se analizaron 36 entrevistas. A partir de éstas, emergieron ciertos instrumentos como los más relevantes a la hora de interpelar el trabajo cotidiano, los que fueron analizados directamente; entre ellos, los sistemas de evaluación curricular adquieren protagonismo al establecer qué acciones cuentan y cuáles no. Las entrevistas también permitieron comprender cómo estos son vividos, desde la posición de los participantes. Ahí emerge la intensificación del trabajo como el proceso más relevante dando cuenta de un trabajo que desborda sus límites ocupando espacios personales, familiares, de descanso y sociales. Esto en un contexto de creciente cuestionamiento a los sentidos del trabajo académico instalados desde las políticas universitarias de alta rendición de cuentas.
Concepções, aproximações e afastamentos de docentes universitários em relação ao movimento sindical
Authors: Pereira da Silva Michelle Karoline , Guimarães André Rodrigues
Published: January 2020

O objetivo deste estudo é analisar o processo de aproximação e afastamento dos docentes universitários do movimento sindical, particularmente no caso de dirigentes do Sindicato dos Docentes da Universidade Federal do Amapá (SINDUFAP), Seção sindical do Sindicato Nacional dos Docentes das Instituições do Ensino Superior (ANDES-SN), destacando a concepção de sindicato que eles defendem no contexto de transformações implementadas por governos neoliberais no Brasil. No âmbito da pesquisa social, este trabalho configura-se como pesquisa de campo, com natureza exploratória. Os sujeitos que participaram da pesquisa foram docentes que atuaram na direção executiva do SINDUFAP, de 1994 a 2018. Evidencia-se, de modo geral, que as problemáticas impostas ao sindicalismo dos docentes, bem como as motivações de aproximação e afastamento do movimento sindical, articulam-se às questões mais amplas das políticas neoliberais implementadas em âmbito nacional, que acarretam consequências negativas que precisam ser refletidas acerca dos limites (e possibilidades) do sindicalismo de modo geral. No bojo das motivações de aproximação e afastamento do sindicato, estão as concepções de sociedade, universidade e sindicato defendidas pelos docentes, ainda que também se registrem outras questões internas da organização que precisam ser enfrentadas.
Trabalho docente no setor privado da educação superior e a reforma trabalhista: Destruição de direitos e precarização da vida
Authors: Do Vale Andréa do Araujo
Published: January 2020

O objetivo deste artigo é apresentar e debater as implicações da dita Reforma Trabalhista (Lei n° 13.467/2017) para o trabalho docente nas instituições de ensino superior (IES) privadas brasileiras. É importante ressaltar que, no caso brasileiro, os impactos desta Reforma precisam ser analisados no bojo do processo de mercantilização, empresariamento e privatização da educação superior, que se expressa de muitas formas, mas aqui analisados pelo prisma da formação de grandes conglomerados educacionais e financeirização do setor, articulando um movimento de concentração e centralização de capital e financeirização do setor, com a abertura de capital, presença de fundos de investimento e de empresas de serviços educacionais internacionais, com amplo apoio em um arcabouço político-jurídico e em políticas públicas sustentados pelo Estado em um país com imensas desigualdades sociais e educacionais. Para este texto, utilizou-se pesquisa bibliográfica e pesquisa documental, com consulta ao banco de leis do Senado Federal, e, ainda, consulta a fontes secundárias, como notícias e informações do Sindicato dos Professores de São Paulo (SINPRO-SP), e dos sindicatos patronais, como a Associação Brasileira das Mantenedoras de Educação Superior (ABMES) e o Fórum das entidades Representativas do Ensino Superior Particular (FERESP). Com base em uma análise crítica, concluiu-se que a Reforma Trabalhista não apenas atendeu aos interesses do setor privado no sentido de precarização e flexibilização das relações de trabalho – e das condições de existência desses trabalhadores -, mas ainda foi objeto de apreciação dos empresários deste setor e seus especialistas antes de seu encaminhamento legislativo, demonstrando o apoio desse.
O trabalho na educação superior

O texto apresenta o dossiê “O trabalho na educação superior”, composto de dez artigos e aborda as mudanças ocorridas no mundo do trabalho no Brasil, a partir do golpe parlamentar, midiático e jurídico que se instalou em 2016. Parte da hipótese de que uma das metas centrais do golpe foi justamente o ataque ao trabalho, seja no sentido distributivo da renda, seja no sentido organizativo dos movimentos sociais e de trabalhadores. Analisa a legislação aprovada no período – Lei nº 13.429/2017 e Lei nº 13.467/2017 –, que tem acarretado um forte retrocesso nos direitos inscritos na Constituição de 1988, e enumera, criticamente, as principais consequências dessa legislação para os trabalhadores como o desemprego, o aumento da rotatividade, a redução salarial, a diminuição do recurso à justiça do trabalho e, consequentemente, aumento das burlas à legislação social protetora do trabalho, o enfraquecimento da organização sindical e maior sofrimento no trabalho, de uma maneira geral. Ao final, desenvolve os impactos dessas mudanças no trabalho desenvolvido nas instituições de educação superior.

Özet
Obezite prevalansı tüm dünyada ve ülkemizde hızla artış göstermektedir. Toplumda artan obezite prevelansı diyabet , kalp hastalığı ve belirli kanserler dahil olmak üzere birçok sağlık probleminin görülme durumunun ve kadınlarda aynı zamanda gebelik, doğum ve doğum sonu dönemde komplikasyon görülme olasılığının da artmasına neden olmaktadır. Bu nedenle obez gebelere doğum ve doğum sonrası dönemde oluşabilecek komplikasyonları da önlemeye yönelik normal kiloda olan gebelerden daha  farklı bir bakım verilmelidir. Birçok ülkede bu bakıma yönelik kanıta dayalı çalışmalardan faydalanılarak oluşturulmuş bakım rehberleri bulunmaktadır. Bu derlemede gebelik, doğum ve doğum sonrası dönemde obezite ile ilgili rehberlerin gözden geçirilmesi amaçlanmıştır.

Bogusław Śliwerski, Extirpation of the scholarly profession in pedagogy.Interdisciplinary Contexts of Special Pedagogy, no. 25, Poznań 2019. Pp. 13-31.Adam Mickiewicz University Press. ISSN 2300-391X. DOI: https://doi.org/10.14746/ikps.2019.25.01.

In the article I am dealing with the issue of unscientific depreciation of pedagogy as a science, which manifests itself either in the lack of reliable scientific criticism of dissertations in this discipline or the escape of some educators into politics to implement their own social intervention projects. The dispute about the scientific nature of pedagogy arises from various research traditions, scientific schools, so the author presents several such methodological approaches, whose creators emphasize the criteria of scientificity and indicate the resulting limitations and their incomparability. Meanwhile, self-awareness of the academic criteria of pedagogy is important in the way of reviewing the scientific achievements of young academic staff. Based on reviews in post-habilitation proceedings, I present various types of arguments in favor of the unscientific status of someone’s research and the reaction of those whose publications are reviewed.

Interdisciplinary Contexts of Special Pedagogy, no. 25, Poznań 2019. Pp. 83-103. Adam Mickiewicz University Press. ISSN 2300-391X. DOI: https://doi.org/10.14746/ikps.2019.25.04

This paper presents an analysis of the social reception of a protest by people with disabilities and their families (and guardians), with a special focus on its educational dimension. The protest took place in the main corridor of the Sejm complex in Warsaw in April and May 2017. The first part of the paper comprises the essential characteristics of social protests. The second provides a brief overview of media information about the discussed protest. The recapitulation of this part specifies the conditions that give the protest an educational dimension. From there, the analysis is narrowed to the reception of knowledge pertaining to the situation of the needs of people with disabilities and their families and the change in attitudes to this social group. The third part comprises a presentation of the research results on this issue. The research was conducted with the use of diagnostic polling—the questionnaire technique, applied to a group of 200 people. The research results show that the protest was a kind of information campaign and that it contributed to some changes in respondents’ knowledge concerning people with disabilities and their families and the transformation of attitudes to their needs.
Miejsce języka polskiego w wielojęzycznym repertuarze uczniów szkół polskich na Litwie
Authors: Masojć Irena
Published: January 2020

Celem artykułu jest wyjaśnienie, jakie miejsce wśród innych znanych i używanych języków zajmuje polszczyzna w komunikacji codziennej i w świadomości młodzieży, uczęszczającej do szkół z polskim językiem nauczania na Litwie. Podstawą materiałową niniejszych rozważań są przeprowadzone w 5 szkołach w maju-czerwcu 2019 r. badania z zastosowaniem metody kwestionariuszowej (116 uczniów) i metody wywiadu pogłębionego (37 uczniów). Uczniowie mieli dokonać samooceny znajomości różnych języków, ujawnić sposób ich akwizycji, zakres użycia w komunikacji i w różnych rodzajach aktywności, ze szczególnym uwzględnieniem nowych technologii komunikacyjnych, wyrazić swoje postawy wobec znanych języków. Wyniki analizy statystycznej danych oraz wypowiedzi uczniów ukazują złożony obraz współwystępowania różnych języków w wielojęzycznym repertuarze młodzieży, w którym miejsce polszczyzny nie jest jednoznaczne.
Nauczanie języka polskiego w polskiej kolonii w Brazylii – studium przypadku
Authors: Goczyła Ferreira Alicja
Published: January 2020

Celem niniejszego artykułu jest przedstawienie wyników badań, których przedmiotem były zajęcia z języka polskiego odbywające się w jednej z polskich kolonii w Południowej Brazylii. Narzędziami metodologicznymi były: ankieta wypełniona przez wszystkich uczących się, obserwacje zajęć oraz rozmowy przeprowadzone z ochotnikami i z nauczycielką. W tekście omówiono kontekst i warunki, w jakich zajęcia się odbywają, oraz opisano grupę uczących się, bardzo zróżnicowaną pod względem wieku i poziomu kompetencji polonistycznych. Ustalono, iż zależnie od przyjętej definicji, wszyscy bądź część uczestników zajęć może zostać zaklasyfikowana jako uczący się języka polskiego jako odziedziczonego (UJOdz). Przeanalizowano również powody podjęcia nauki przez uczących się oraz jej cele. Na podstawie obserwacji oraz rozmów z uczestnikami wywnioskowano, że zajęcia nie są dostosowane do potrzeb UJOdz, czego głównym powodem jest brak dostępu do specjalistycznych szkoleń dla nauczycieli i odpowiednich materiałów dydaktycznych.

Horticultural Therapy and Gardening – Comparison of Dimensions
Authors: Gulczyńska Anna
Published: January 2020

There is growing attention to findand popularize untypical forms of therapy which should help patients in hospitals, occupational facilities and clinics. The main aim of the article is to show the differences between horticultural therapy as a form of therapy and work in a garden, which can also provide therapeutic results. Comparison of different determinants was a method to outline that proper understanding of the differences may be beneficialboth for theoreticians and practitioners who use nature in order to improve their patients’ health. However, it is useful for future teachers and could play a role in the teacher education process. As a conclusion, it has been established that source literature scientificreports focus rather on potential recipients or benefitswhich come from this form of therapy, whereas basic differences between gardening and horticultural therapy have been rarely mentioned. Analysis has helped to observe that there are many factors which differentiate therapeutic work in the garden from work in the garden which can bring therapeutic effects. Performing such an analysis seems to be significantin connection with the growing popularity of centers which offer this kind of therapy, and with the emergent dilemmas concerning how it differs from gardening and whether the therapy is worth the money invested in it.
Teaching Culture Through ICT in a Postmodern World – (Un)Used Possibilities of New Technologies
Authors: Sikorska Joanna
Published: January 2020

Teaching culture of foreign countries was until recently done by traditional means i.e. movies, letters sent by post to schools in other countries or by means of a textbook. Now, when schools are getting more computerized, certain elements of teaching have been revolutionized. They include, for example, culture teaching, which received a new meaning through the use of eTwinning. Because of it, teachers and students can communicate much easier through the platform, Facebook or by e-mail with other schools from the EU that are in this program. They can take part in projects with other schools and learn the cultural differences between their countries together. In this article I try to point out the challenges which multicultural ICT use can bring to education.
