PLACENTAL THICKNESS AND ITS CORRELATION TO GESTATIONAL AGE ESTIMATED BY FOETAL GROWTH PARAMETERS-A CROSS SECTIONAL ULTRASONOGRAPHIC STUDY
Authors: Ahmad M , Anjum MN , Asif M , Ayub S , Muzaffar A , Mubeen I
Published: September 2021

The placenta is a meterno-fetal organ and starts developing on the 5th week from chorionic villi at the implantation site. The placenta continues to increase in thickness and hence its thickness can be used to indicate the gestational age when the last menstruation date is not confirmed. The purpose of the study was to find out the correlation of placental thickness to the gestational age estimated by growth parameters of the fetus. The study was a cross-sectional analytical study conducted on 2000 participants. The study was conducted in the Department of Radiology Social Security Hospital, Multan Chungi Lahore. The inclusion-exclusion criteria were established and participants were observed using a Toshiba ultrasonography machine. The subjects were placed supine and placental thickness was measured to the accuracy of 1mm. Pearson’s correlation was applied to find out the correlation between placental thickness and gestational age of the participants. The mean age of the participants was 28.37  +  4.6. The youngest participant was age 18 and the eldest participant was age 40. The gestational age of the participants included ranged between 12th week to 40th week. Pearson’s correlation score indicated that the correlation value 0.896. Which indicated that the placental thickness and gestational age were strongly correlated? The P-value < 0.05 indicated that the results were significant. The study concluded a strong correlation between gestational age and placental thickness of the fetus. The thickness of the placenta increased with an increase in gestational age and hence could be used as a predictor and a parameter of gestational age prediction when the last menstruation is uncertain or is unknown.

Published: September 2021

Bioplastics are biodegradable polymers that are made by bacterial cells, whose molecules have biochemical properties similar to petrochemical polymers as they are concentrated inside intracellular granules as a carbon and energy sources, and which then degrade in the environment as they get exposed to light. Bioplastics have desirable biodegradable and renewable qualities, sustainable qualities as well as alternatives to petroleum-based plastics, and is used due to much of its biodegradability and durability. Due to their vast usefulness, Poly Hydroxy Alkanoate (PHAs) and their derivatives are used in many different sectors, PHAs are the most biodegradable bioplastics found throughout the world. These polymers are generated by microorganisms through metabolic pathways that start with hydroxy-acyl-A and end with different types of acyl-A. Bioplastic polymers have chemical characteristics that differ in structural and physical properties which also differ due to the source of their polymerization microorganisms.

Authors: Knuth Ingo , Masuhr Janina
Published: September 2021

This study analyzes the central factors influencing the satisfaction and future use of search engines. It examines the influence of technological lock-in effects (e. g. operating systems / browsers providing pre-settings), as well as basic product- and brand-related factors (e. g. search results, user experience, brand image). Data was collected via a quantitative online survey in Germany, which resulted in 236 respondents providing statements about their most recently used search engine. The data shows that all independent variables have a strong impact on the satisfaction with a search engine as well as future usage and explain a lot of the variance of the dependent variables. The satisfaction with the core product has the strongest impact, followed by brand-related aspects and user experience. The results also show an impact of a search engine preset in the browser effects that influences the role of brand and the evaluation of different product characteristics.
The paradigm of statistical inference and the paradigm of statistical learning
Authors: Pociecha Józef
Published: September 2021

The starting point for the presentation of the similarities and differences between the principles of conducting statistical research according to the rules of both statistical inference and statistical learning is the paradigm theory, formulated by Thomas Kuhn. In the first section of this paper, the essential features of the statistical inference paradigm are characterised, with particular attention devoted to its limitations in contemporary statistical research. Subsequently, the article presents the challenges faced by this research jointly with the expanding opportunities for their effective reduction. The essence of learning from data is discussed and the principles of statistical learning are defined. Moreover, significant features of the statistical learning paradigm are formulated in the context of the differences between the statistical inference paradigm and the statistical learning paradigm. It is emphasised that the statistical learning paradigm, as the more universal one of the two discussed, broadens the possibilities of conducting statistical research, especially in socio-economic sciences.
Kako se pisalo i kako se danas treba pisati o historiji Drugog svjetskog rata u Bosni i Hercegovini?
Authors: Goldstein Ivo
Published: September 2021

U ovom tekstu autor analizira metodološke koncepte koji su tijekom desetljeća bili korišteni u pisanju povijesti Drugog svjetskog rata u Bosni i Hercegovini te kako bi valjalo pisati danas. Umjesto da se lakune u znanjima koje su skrupulozni istraživači s demokratizacijom i liberalizacijom nakon 1990. godine mogli popuniti, pritisak politike i rat snažno su pridonijeli novim mistifikacijama i mitologizacijama. Štoviše, neke već utvrđene činjenice dovedene su u sumnju ili su čak u dijelu javnosti posve odbačene. Međutim, usprkos manjku istraživača, nepostojanju volje dijela istraživača da istražuju “nezgodne” činjenice i procese iz Drugog svjetskog rata, u znanjima o tom razdoblju bosanskohercegovačke povijesti u posljednjim desetljećima napravljeni su neki, čak i značajni pomaci nabolje. A i neki relativno novi tekstovi daju osnove za optimizam
The historiography of the Bosnian genocide of 1992–1995 in the work of foreign scholars
Authors: Hoare Marko Atilla
Published: September 2021

This essay will provide an introductory discussion of the historiography of the Bosnian genocide of 1992–1995 in the works of foreign scholars. The historiography is too large for this discussion to be exhaustive. We have attempted here to provide the principal categories of relevant works while citing the most important examples of them, before discussing the historiographical deficiencies and the tasks awaiting future scholars of the genocide. The reason for the dearth of monographs on the Bosnian genocide is that the subject is highly controversial, and any scholar who seriously studies it and expresses an opinion is likely to create enemies for themselves. There is a tendency of scholars to see the war in postmodernist terms, in terms of Serb, Croat and Bosniak “narratives”; as opposed to objective truth, which discourages taking the subject intellectually seriously. Furthermore, the prevailing ideology and discourse stemming from the international administration is one of reconciliation and putting the past behind us. So there is a disincentive to study the genocide in depth; a preference for studying more liberal feel-good themes related to reconciliation, memory, transitional justice and post-war reconstruction. The Bosnian genocide therefore awaits a new generation of foreign scholars to take it seriously as a subject and explore it in detail.
Sjeveroistočna Bosna – pozitivan primjer razvoja lokalne historiografije
Authors: Mutapčić Edin
Published: September 2021

Područje sjeveroistočne Bosne je do prije četiri decenije bilo veoma slabo obrađeno u historijskoj nauci, što je uostalom prepoznala i ANUBiH koja je programom Društveni cilj (DC) XIII 2 iz 1986. godine upozorila na navedenu činjenicu. Međutim, pisanje monografija pojedinih općina koje se odnose na NOR 1941–1945. godine otvorilo je istraživačke projekte vezane za lokalnu historiografiju na navedenom području. Tako se u narednom periodu počinje sa značajnijim istraživanjem ove regije u historijskoj nauci. Tome je značajan doprinos otvaranje Odsjeka za historiju i geografiju, odnosno historiju na Filozofskom fakultetu Univerziteta u Tuzli. Tako nastaju brojni radovi na teme koje se odnose na pojedine periode bosanskohercegovačke historije navedenog područja. Nastaju značajne monografije, rade se doktorske disertacije i drugi radovi. Pojavljuje se nekoliko lokalnih časopisa, ali i drugih istraživačkih projekata, koji kontinuirano obrađuju teme iz navedene problematike. Rezultati tih istraživanja su prezentirani u ovom radu.
Historiografska literatura i izvori o Bihaćkoj Krajini u dvadesetom vijeku, objavljeni od 2000. do 2017.
Authors: Pašić Jasna
Published: September 2021

Bihaćka krajina je, kao sjeverozapadna regija Bosne i Hercegovine, tokom 20. stoljeća bila zahvaćena krupnim historijskim kretanjima koja su u većoj ili manjoj mjeri odredila njenu prošlost. Dio promjena se reflektirao iz ukupnih društveno-političkih, vojnih privrednih i kulturnih tokova bosanskohercegovačke zbilje, dok su neke od njih lokalnog karaktera i ukazuju na osobenosti krajine. Historiografska literatura, nastala u posljednje gotovo dvije decenije, pokazatelj je istraženosti ovog područja u pojedinim bitnim segmentima. U radu je cilj ukazati na historiografsku literaturu i objavljene izvore o Bihaćkoj krajini, s fokusom na periode prijelomnih događaja i procesa koji su obilježili prošlost ovog kraja u 20. stoljeću. U tom smislu je riječ o interesu naučnih i stručnih krugova koji su svoja istraživanja usmjerili na početak 20. stoljeća, odnosno austrougarski period, zatim Drugi svjetski rat i događaje iz socijalističkog razdoblja koji su regiju sjeverozapadne Bosne i Hercegovine doveli u središte pažnje šire javnosti ili zainteresirali historičare. Izdvojena su djela i radovi čiji su autori primarni tematski okvir istraživanja usmjerili na prošlost ovog geografskog područja i istraživanja koja tretiraju širi kontekst bosanskohercegovačke prošlosti, ali u svojim okvirima sadrže značajne podatke za sjeverozapadnu Bosnu. Za ratni period 1992–1995. ukazuje se na dostupne objavljene historijske izvore i memoarske zapise. Razlog izostavljanja literature je pojačan interes za ratnom prošlošću nakon 1990-ih, gdje je došlo do produkcije literature većeg obima koja bi zahtijevala detaljniju historiografsku analizu, što bi činilo zaseban istraživački rad na tu temu.
Historiografija o Bosni i Hercegovini u bosanskohercegovačkim udžbenicima historije (2000–2017)
Authors: Forić Plasto Melisa
Published: September 2021

U radu se analiziraju udžbenici historije izdati i korišteni u Bosni i Hercegovini u periodu 2000–2017. radi sagledavanja na koji način su rezultati historiografskih istraživanja o Bosni i Hercegovini inkorporirani u njihov sadržaj. Uzimajući u obzir da udžbenik u Bosni i Hercegovini, kao i u većini evropskih zemalja, i dalje služi kao osnovno nastavno sredstvo u podučavanju nastave historije te da na neki način predstavlja kanonizirano znanje, službenu verziju prošlosti koja je preporučena ili bolje reći propisana od strane državnih autoriteta, nastojalo se sagledati kakvi su historiografski odrazi o Bosni i Hercegovini dati u njima. Specifičnost udžbeničke i obrazovne politike u Bosni i Hercegovini ogleda se u dubokoj podijeljenosti na etno-nacionalnom principu te dodatnoj rascjepkanosti uslovljenoj administrativnim uređenjem Bosne i Hercegovine nakon Dejtonskog sporazuma. Umjesto jedinstvene historiografije o Bosni i Hercegovini u udžbenicima nailazimo na različite pristupe. U nekim od njih podaci o prošlosti Bosne i Hercegovine su dosta skromni ili gotovo izostavljeni, a naglasak je stavljen na prošlost susjednih država Srbije ili Hrvatske ili srpskog ili hrvatskog naroda. Radom se nastoji sagledati kakva se poruka o prošlosti šalje generacijama koje koriste udžbenike kroz svoje obrazovanje i kakvu ulogu ona ima za budućnost ove zemlje.

Published: September 2021

Queimadas são uma ameaça a conservação dos ecossistemas em especial em Unidades de Conservação, territórios de grande valor considerando seus atributos físicos e bióticos, podendo resultar em impactos significativos e duradouros tanto do ponto de vista ecológico, como social e econômico. O objetivo deste trabalho foi realizar um mapeamento de áreas susceptíveis a risco de incêndio na APA Sul RMBH com uso de técnicas de geoprocessamento. Foi utilizada a análise multicritérios pelo modelo de Análise Hierárquica de Processos (AHP) considerando dados secundários referentes às características fisiográficas e socioeconômicas da área de estudo. O mapa resultante, com as áreas de maior risco a ocorrência de incêndios, indicou predominância de risco médio ao longo da APA Sul, sendo que as áreas de alto risco concentraram-se em locais com as menores cotas altimétricas do recorte, declividades mais planas, em locais de pastagem e mosaicos de agricultura, regimes de precipitação e temperatura intermediários, enquanto que as áreas menos propícias a incêndios localizaram-se em locais de afloramento rochoso, elevada altimetria, declividade montanhosa a escarpada e afastadas das principais localidades e rodo-ferrovias. Acredita-se que o uso de geotecnologias para esse fim possa subsidiar no planejamento e gestão desta importante unidade de conservação.
A involução Cartográfica da Vila de São João Batista do Presídio
Authors: Paula Lucas de , Carrara Angelo Alves , Carrara Angelo Alves , Gomes Francisco Carlos Moreira , Zaidan Ricardo Tavares
Published: September 2021

O Estado brasileiro enfrentou ao longo do século XIX o desafio de ordenar o território no interior das províncias. A forma como se estabeleciam os limites municipais era um problema e o crescimento do número de municípios principalmente a partir da década de 1830 dificultou ainda mais a delimitação da área dos municípios. Junto a essa questão a constituição político-administrativa se apresentava de uma forma muito mais complexa como conhecemos atualmente. Se os municípios atualmente são subdivididos apenas em distritos, anteriormente os poderes políticos, judiciários e eclesiásticos participavam do ordenamento territorial e diferentes categorias se sobrepunham gerando um complexo ordenamento territorial. A cidade de Visconde do Rio Branco, localizada no sudeste de Minas Gerais tem seu processo de formação inserido dentro desse contexto. Quando ainda povoado denominava-se Aldeia do Xopotó dos Coroados, e o município foi criado somente em 1839 após ser desmembrado de Pomba com a denominação de Vila de São João Batista do Presídio. O município do Presídio tem um papel importante na consolidação da territorialidade da porção central da zona da Mata mineira, do seu território originaram-se 49 municípios. Nesse sentido o objetivo dessa pesquisa é realizar um estudo de involução territorial, partindo da atualidade até o ano de criação da Vila de São João Batista do Presídio em 1839. A metodologia adotada fundamentou-se em pesquisas bibliográficas e levantamento de base de dados cartográfica. Os principais resultados obtidos consistem na representação cartográfica do limite territorial de Visconde do Rio Branco para diferentes períodos, a Genealogia a partir da Vila de São João Batista do Presídio e a comparação da divisão política legal com a divisão do IBGE (Instituto Brasileiro de Geografia e Estatística). Dessa forma, espera-se que a pesquisa possa contribuir com informações e materiais cartográficos que enriqueçam a geografia-histórica do município de Visconde do Rio Branco e também dos municípios que se desmembraram de seu território original.
MODEL OF DECOMPRESSION MELTING MECHANISM IN CONVECTIVE-UNSTABLE THERMAL LITHOSPHERE (FIRST APPROXIMATION)
Authors: Lunev B. V. , Lapkovsky V. V.
Published: September 2021

We propose a model of decompression melting, separation, migration and freezing of the melt in the upper mantle during the convective instability process. The model takes into account differences between phase diagrams of the melt and the matrix and the resultant features of the melt’s behavior, without calculating reaction rates in a multicomponent medium. It is constructed under an explicit concept of the local thermodynamic equilibrium of the existing phases. Therefore, we further develop the first approximation of the descriptions of convection in the upper mantle and the formation of large epicontinental sedimentary basins, which have been presented in earlier publications. Our computational experiments show that primary melting of the upper mantle’s fertile material occurs intensively in a narrow frontal part of the ascending hot material flow. Then, the depleted and partially melted material rises farther upward from the front of primary melting. Melting of the depleted material continues at lower pressures in a rather wide range of depths (120–77 km). Further, the migrating melt is supplied by two sources, i.e. a deep-seated one, wherein the fertile material melts, and the medium-depth one, wherein melting of the depleted material takes place. Once the temperature and pressure rates of the melt reach the values corresponding to those of its solidus, a narrow freezing front is formed. Its width is almost similar to the primary melting front. As the ascending convective flow develops, the freezing front shifts upward. As a result, a quite thick (around 40–50 km) basalt-saturated layer occurs above the freezing front. An important observation in our modeling experiments is that, despite a considerably large total volume of the melted material, a one-time melt content in the mantle does not exceed tenths of one percent, when we consider averaging to volumes with a linear size of about 1.0 km. The basalt melt extraction depletes iron in the mantle and significantly reduces the mantle density. Considering the calculated basalt-depletion values for the matrix at 0.1–0.2, the density deficit doubles in comparison to the thermal expansion of the material. Logically, both the Rayleigh number and the intensity of convection also double (and this is confirmed by the calculations), which means that convection is enhanced after the melting start.

Testing of the model shows that it gives a reasonable picture that is consistent with the available geological and geophysical data on the structure of the lithosphere underneath the currently developing epicontinental sedimentary basins. Furthermore, within the limits of its detail, this model is consistent with the results of modeling experiments focused on melting and melting dynamics, which are based on calculations of reactions between components of the mantle material.
STRESS FIELD IN A SHEAR ZONE, AND FORMATION OF THE MAIN FAULT
Authors: Lermontova A. S.
Published: September 2021

Using the analytical approximation method, we calculated stress field parameters for cases with different relative positions of Riedel shears and loads required for shearing. Considering an internal friction angle of 30°, and the distance between adjacent shears exceeding 0.7 of the characteristic shear length, we estimated the Coulomb stress that can lead to fracturing. In the areas between the shears, it is below the shear strength value. This means that if an increase in the external load is lacking, there are no prerequisites for the formation of new fractures that may connect adjacent shears. If the shears are spaced closer to each other (i.e. at distances less than 0.7 of the shear length), the shear strength is exceeded in the areas between them, and new shears can occur there and connect the Riedel shears to each other. Therefore, in observations of a natural system of Riedel shears, it becomes possible to assess whether this system is sufficiently stable in its current status, or, in case of a critical increase in the Coulomb stress in the areas between adjacent shears, the equilibrium can be easily disturbed, and there is a possibility that the main fault forms in the strike-slip zone under study.
REPLY TO COMMENTS FROM S.G. SKUBLOV, A.V. BEREZIN, AND L.I. SALIMGARAEVA ON THE ARTICLE AUTHORED BY M.V. MINTS AND K.A. DOKUKINA – THE BELOMORIAN ECLOGITE PROVINCE (EASTERN FENNOSCANDIAN SHIELD, RUSSIA): MESO-NEOARCHEAN OR LATE PALEOPROTEROZOIC?
Authors: Mints M. V. , Dokukina K. A.
Published: September 2021

In their research, the authors of the comments have focused on the Late Paleoproterozoic rims of zircons, but ignored many important details of their own data. Their comments are based on a misconception that eclogite zircons have unique geochemical (REE, Th/U) and isotopic (Lu-Hf, δ18O) characteristics that do not depend on rock types and pressure rates (that were high or ultrahigh) during metamorphism. This idea leads to false unambiguous dating of the eclogite facies metamorphism based on single samples of the rocks.

Authors: Moallemi Sedighe , Sahahbakhsh Behnaz , Bakhshani Nour-Mohammad , Salaridargi Zohreh
Published: September 2021

Background: Tattoos or stencils on the body have a special charm for the people of different cultures. The fact that such stencils are considered attractive and essential to some people from a specific culture has led to the conclusion that there might be factors which make tattooing attractive to someone. Objectives: The present study aimed to determine and compare behavioral activation system (BAS), behavioral inhibition system (BIS), and fight-or-flight system between tattooed and non-tattooed substance-dependent individuals. Methods: Using convenience sampling method, this study included 146 substance-dependent individuals (73 tattooed and 73 non-tattooed) referring to Baharan rehabilitation center in Zahedan, Iran. Data collection was done by the short form of the Gray–Wilson Personality Questionnaire (GWPQ), and data were analyzed by independent t-test. Results: According to the results of GWPQ, in BIS, in tattooed individuals, extinction and total scores of avoidance was significantly higher than non-tattooed. Meanwhile, there was no significant difference between BAS and fight-or-flight system. Conclusions: While BAS is associated with positive emotions, BIS is associated with negative emotions. The tattoo seems to be a sign of special personality characteristics and can be used as a way to extinction the emotions and avoiding to deal with pejorative emotions.

Práticas incentivadoras e controle de aprendizagem na alfabetização
Authors: Monteiro Maria Iolanda
Published: September 2021

Esste trabalho consiste na investigação da variedade de ações educativas de uma professora alfabetizadora e suas relações com o rendimento escolar dos alunos, visando compreender as práticas, sem perder de vista elementos que fazem parte da escola e de seu contexto. Para alcançar os objetivos, utilizaram-se entrevistas e observação participante. A análise do cotidiano da sala de aula envolveu o estudo das práticas incentivadoras para identificar as relações que contribuíram para o controle de aprendizagem na alfabetização. Nessa perspectiva, organizaram-se outras classes de dados para se estudar esse controle, como a natureza da atividade, natureza de participação da professora e dos alunos, práticas avaliativas e situações de (re)ensino. Os resultados permitiram identificar que as práticas pedagógicas apresentam caráter contraditório, porque foram organizadas para facilitar a compreensão, eliminar as dificuldades, dúvidas e para desenvolver certas habilidades, mas não ofereceram muitas situações de desenvolvimento, de tal modo que o aluno pudesse ultrapassar os padrões estabelecidos pela educadora e apresentar diferentes resultados. Concluiu-se que as características do desempenho escolar apresentaram uma dependência significativa das práticas da educadora. Percebeu-se ainda, ao se analisar a configuração do cotidiano escolar, que continua fazendo parte da realidade das práticas pedagógicas nas escolas a preocupação em homogeneizar e classificar o desempenho, disseminando, assim, um controle que encaminha os alunos a reagirem de determinadas maneiras. A investigação da variedade de ações educativas evidencia a importância de um desenvolvimento profissional docente, cujo processo de profissionalização abrangesse o investimento na identidade de professor alfabetizador. Palavras-chave: Práticas alfabetizadoras. Identidade de professor alfabetizador. Formação docente.
Brincadeiras de crianças Mbyá-Guarani no urbano: reflexões acerca da Antropologia e da Psicologia da Educação
Authors: Jesus Suzana Cavalheiro de
Published: September 2021

O presente texto é composto por resultados parciais de uma pesquisa de campo etnográfica, realizada junto a um grupo Mbyá-Guarani no urbano de Santa Maria, Rio Grande do Sul, e apresenta reflexões acerca de algumas brincadeiras desenvolvidas pelas crianças Guarani em seu território, um acampamento indígena, e também no centro da cidade, onde acompanham a venda de artesanato. Assim, objetiva-se, por meio desse trabalho, estabelecer relações entre o ato de brincar e a constituição dos modos de ser indígena, bem como compreen-der as práticas de educação não escolar presentes nessas brincadeiras. Nesse sentido, busca-se evidenciar vínculos entre a Psicologia do Desenvolvimento e a Antropologia Social, enquanto disciplinas que procuram compreender e explicar os processos de ensino e aprendizagem dos grupos sociais. Para tanto, faz-se necessário salientar que não se pretende, nesse texto, discutir sobre a inter-dependência epistêmica que a educação tem com outras áreas do conhecimento (GOERGEN, 2005), como, no caso aqui, a Psicologia e a Antropologia. A intenção é descrever, sob a ótica destas disciplinas, algumas brincadeiras que foram vivenciadas em observação participante e analisadas através de uma abordagem interpretativa da cultura, nos termos de Geertz (1989). Palavras-chave: Brincadeiras. Cultura. Modos de ser Guarani Mbyá.
Gestão escolar: a prática pedagógica administrativa na política de educação inclusiva
Authors: Tezani Thaís Cristina Rodrigues
Published: September 2021

Este trabalho apresenta os resultados de uma tese de doutorado que teve como tema a análise dos saberes que envolvem a prática pedagógica e administrativa cotidiana de gestores escolares que atuaram com a proposta de construção de um sistema municipal de educação inclusiva, enquanto política educacional. Seu objetivo foi acompanhar a trajetória da gestão escolar diante da proposta de educação inclusiva em três escolas do ensino fundamental de uma cidade de porte médio do interior do Estado de São Paulo. Realizou-se a coleta de dados na escola mais antiga, uma de idade intermediária e outra recém-inaugurada. As etapas do trabalho foram: 1) revisão de literatura sobre: a) pesquisa qualitativa do tipo etnográfico aplicada à educação; b) princípios de autonomia, planejamento, descentralização; c) formação do gestor escolar e d) relação entre gestão escolar e a escola inclusiva; 2) coleta de dados nas escolas; 3) descrição e categorização dos dados e 4) análise e interpretação dos resultados. Para o desenvolvimento da metodologia, foram utilizadas observações dos participantes, entrevistas semiestruturadas, análise dos documentos oficiais das escolas (internos e externos). Concluiu-se que há inexistência de projeto político-pedagógico construído coletivamente; dificuldade no desenvolvimento de ações coordenadas e adaptadas às realidades; problemas de relacionamento interpessoal; fosso entre a proposta política, o discurso e a prática pedagógica cotidiana. A gestão escolar é uma das responsáveis pela construção da escola inclusiva, mas, na realidade estudada, estava direcionada para questões administrativas em detrimento das pedagógicas.

Alunos com deficiência física: a compreensão dos professores de Educação Física sobre a acessibilidade nos espaços de prática para as aulas
Authors: Palma Luciana Erica , Manta Sofia Wolker
Published: September 2021

No âmbito das Políticas Educacionais, uma série de transformações vem ocorrendo desde as décadas de 1980-1990, no que diz respeito à inclusão de aluno com deficiência na rede regular de ensino. O estudo teve por objetivo analisar a compreensão dos professores de Educação Física e Séries Iniciais sobre a participação do aluno com deficiência física em aulas de Educação Física e a acessibilidade dos espaços de prática. Os professores participantes são de uma Escola Pública da Rede Regular de Ensino de uma cidade do Rio Grande do Sul. O instrumento utilizado para a coleta de dados foi uma entrevista semiestruturada com roteiro preestabelecido aos professores de Educação Física e aos professores de Séries Iniciais que ministravam aulas para turmas com inclusão de alunos com deficiência física. Por meio da análise dos dados nas entrevistas com as professoras, identificou-se que os espaços de prática das aulas de Educação Física não possuíam acesso nem a acessibilidade que garantissem a segurança e autonomia do aluno com deficiência física (DF), porém, estes alunos não deixavam de participar das aulas de Educação Física. Pode-se perceber, ainda, as barreiras atitudinais que o aluno com DF enfrenta no cotidiano da Escola e que precisam ser, urgentemente, eliminadas para que a inclusão desses alunos ocorra de forma participativa e livre de preconceitos. Por fim, é importante que, a partir de uma ação conjunta com toda a comunidade escolar, os espaços estejam cada vez mais acessíveis para serem utilizados por uma gama maior de pessoas.

Rethinking the connections between campus courses and Field experiences in College and University-based teacher education
Authors: Zeichner Ken
Published: September 2021

In this paper, I discuss one of the central problems that has plagued college and university-based pre-service teacher education for many years, the disconnect between the campus and school-based components of programs. First, I will draw on my own experiences as a teacher educator and administrator over the last thirty plus years at the University of Wisconsin-Madison and the literature to lay out various dimensions of this issue. Then, utililizing the concept of hybridity and “third space,” I will discuss a variety of current work in programs across the U.S. that offers much promise in deepening the quality of teacher learning in college and university-based teacher education programs and the ability of teacher education graduates to enact desired teaching practices in complex school settings. This work in creating hybrid spaces in teacher education where academic and practitioner knowledge and knowledge that exists in communities come together in new less hierarchical ways in the service of teacher learning represents a paradigm shift in the epistemology of teacher education programs. I argue that this shift toward more democratic and inclusive ways of working with schools and communities is necessary for colleges and universities to fulfill their mission in the education of teachers. Keywords: Education of teachers; Campus and school-based; Programs across.

Published: September 2021

The quality of the teaching process highly depends on teachers and their qualifications, and the teacher's role plays a very important part in the implementation of the new teaching methods. The results presented in this paper are part of the quantitative study which investigated the primary teachers' perception of the online teaching model that has been realized in Serbia during the COVID-19 pandemic, in comparison to the traditional teaching model. The paper aims to define and present the teachers' profiles, based on their preference for a certain teaching model: the profile of the teachers who prefer working in the traditional teaching model, and the profile of the teachers who prefer working in the online teaching model, or do not make any difference between the two, based on the professional data and their statements and attitudes regarding the comparison of traditional and online teaching models. It was assumed that the teachers with less work experience, more professional training and higher education level would generally prefer the online teaching model. For the research purposes, the specialized two-part questionnaire was designed. The first part included questions concerning the socio-demographic background, while the second part investigated the teachers' attitudes towards the characteristics of the teaching process in both traditional and online teaching models. The independent-sample t-test was used to estimate the influence of previous training on the choice of the preferred teaching model. The research was conducted during January and February 2021. The research sample included 609 examinees. The research results showed that the choice of the preferred teaching model depends on the self-assessment of the teachers' competencies required for the online teaching model, as well as on the duration of the training in the field of Information and Communication Technologies, as a part of the regular professional improvement training. The initial assumption was only partially confirmed by the research results.

Published: September 2021

The aerodynamic properties of five varieties of Yam namely: white yam, purple yam, three leaves yam, water yam and yellow yam were investigated under oven drying methods at 33oC. The dried yams were milled to flour and were taken to laboratory to determine their aerodynamic properties with respect to pneumatic conveying of the yam flours. The yam flour varieties recorded terminal velocity range of 1.38 to 1.60 m/s. Drag coefficient of 0.47 and Reynolds number varying from 0.63 to 0.97x10-5 kgm-2 /s. The analysis of variance conducted on the effect of yam varieties on the aerodynamic properties of yam flour did not show significant difference at both 5% and 1% level of probability. The study will guide engineers in design of yam flour pneumatic conveying equipment.

Authors: Obasa Peter , Adejumo Bolanle
Published: September 2021

Optimization of process parameters of many existing biolubricant were carried out based on the factor interactions and yield without putting the physicochemical properties into consideration. The aim of the work is to optimize the reaction temperature and time for the production of high-quality biolubricant using set objectives in relation to the physicochemical properties of the bio-lube produced. The reactor used consists of a reactor tank (2500 cm3 ), temperature, time, stirrer (agitation), speed ranged between 0 - 300oC, 0 - 120 minutes and 80 - 500 rpm respectively. The optimum temperature and time design matrix using Response Surface Methodology (Doptimal design) in Design Expert 11.0 software package. The results of the optimized yield of the castor seed oil biolubricant produced were compared with international standards for lubricant. The result shows better yield in the operational process of the fuzzy logic-controlled reactor. The yield of biolubricant for the experimental design matrix produced using the fuzzy logic reactor ranged between 79 - 96 %. Higher values were obtained from the study, except for the pour point values that were lower. The higher yield and the physical and thermal properties in castor oil biolubricant from the fuzzy logic temperature-controlled reactor could be as result of the uniform temperature and reaction time during the production process. The optimum condition for the bio-lube produced considering the optimum set goals for best quality biolubricant produced considering the set goal objective to comprise all the physico-thermal properties obtained in the study. The optimum condition was obtained at ninety-nine (99.5) minutes reaction time and 250oC reaction temperature with desirability value of 0.76. with the physico-thermal properties of 96.48 %, 33.7 mPa.s (33.7 cP), 15.5 mPa.s (15.5 cP), 179.9oC, 291oC, 15.9oC, for viscosity at 40oC, viscosity at 100oC, viscosity Index, Flash point, pour point. The physicochemical properties of biolubricant produced at optimum condition are within the recommended international standard. It can be concluded that the fuzzy logic-controlled reactor product is better biolubricant considering the number of parameters set goal to determine the optimum condition for production.
O Theatrum Mundi pós-moderno: o jogo da vida, a vida como jogo
Authors: Maffesoli Michel
Published: September 2021

Quanto à recomposição pós-moderna, o que ela pode ser? É claro que é sempre muito delicado "remoer" nos potes do futuro. No entanto, é possível dar algumas indicações, reunir alguns indícios, a fim de indicar as grandes tendências. Tanto mais, como já foi dito, que vemos retornar, ligeiramente modificado, o que tínhamos acreditado ter sido ultrapassado. Para ser mais preciso, não se trata, aqui, de um "eterno retorno do mesmo", mas, como o filósofo Nicolau de Cusa apontava em seu tempo, de um crescimento assumindo a forma de uma espiral. Para dizê-lo ainda mais nitidamente, se uma definição provisória de pós-modernidade devesse ser dada, ela poderia ser "a sinergia dos fenômenos arcaicos e do desenvolvimento tecnológico".
ПРВИ МОДЕРНИ ЛИТЕРАТ СРПСКИ Тихомир Остојић о Јовану Стерији Поповићу
Authors: Певуља Душко
Published: September 2021

У раду се детаљно анализира расправа књижевног историчара Тихомира Остојића посвећена Јовану Стерији Поповићу. Настала на основу предавања одржаног у Матици српској поводом двоструке Стеријине годишњице, она представља вриједан прилог проучавању дјела овога писца и један од најбољих радова који је Остојић уопште написао. Остојић сагледава књижевноисторијски статус Стеријиног опуса и његов значај у токовима српске књижевности, истиче жанровску разноврсност његовог дјела, освјетљава његова тежишна поетичка својства те успоставља, у оквирима једног богатог и разноврсног стваралачког комплекса, поуздан вредносни поредак. Поред наведене студије, узети су у разматрање и краћи написи Тихомира Остојића о Стерији, као и портрет који је овај заслужни проучавалац наше књижевне прошлости о њему сачинио у својој Историји српске књижевности из 1923. године.
ВРЕМЕНСКО-ПРОСТОРНИ ОКВИРИ ТЕАТРАЛИЗОВАНИХ ПРАЗНИКА

Празник се рађао у дугом процесу формирања обредних и обичајних права и постепеног сазријевања њихових властитих изражајних средстава, као што су маске, музика, игре, разни реквизити и др. Почетке појаве и развоја празника многи теоретичари постављају у временско-просторне оквире слободног времена или доколице, која је за циљ имала осмишљавање разноврсних театрализованих приказа, дромена, ритуалних похода и обредних радњи забавног и магијског карактера, гдје су игра, пјесма и весеље имали примарну улогу.
ИСТОРИЈА И ЛЕГЕНДА
Authors: Ђерић Зоран
Published: September 2021

Историја и легенда су кључне речи Андрићеве поетике. Отуда и наслов 12. књиге сабраних дела Иве Андрића (Београд 1976). Наш велики писац и једини наш Нобеловац није, нажалост, писао о позоришту и није писао драме, осим једног драмолета, раног покушаја у младости. Ипак, многа његова прозна дела су доживела драматизације и сценска упризорења. Али овде неће бити речи о њима. Већ о томе колико је у позоришту данас присутна тема историје.

Published: September 2021

With the recent development in network technology over a few years, digital works can be easily published online. One of the main issues in the field of digital technology is the infringement of digital works, which can seriously damage the data owners’ rights and affects the enthusiasm of the owners to create original work. Thus, more attention is required for the protection of digital copyright as it has a great impact on the development of society. Many digital copyright protection techniques were developed in the past, but still, there are many loopholes in the protection systems to be covered. The protection means are still relatively weak, timeliness is poor, infringement is frequent, a right determination is cumbersome, and the results are not ideal. Aiming at the mentioned problems, this paper proposes a protection technique, which can realize the automatic management of the complete digital rights life cycle on the blockchain using fabric's smart contract technology. The proposed system is based on blockchain technology, which leverages the distributed, tamper-proof and traceable characteristics of blockchain. The system uses smart contracts to manage the full life cycle of digital copyright. The test results show that the proposed system provides effective protection of the digital copyright system and can efficiently confirm the rights of digital copyright.
