EDUCAÇÃO E LITERATURA: POR UMA ESTÉTICA DO ISOLAMENTO SOCIAL
Authors: Baptista Ana Maria Haddad
Published: April 2021

A Educação, em tempos de isolamento social exigido pelo Corona Vírus 19, exige e exigiu uma nova postura de estudantes e professores. A ruptura brutal e sem precedentes no processo educacional possibilitou aberturas para discussões, a partir de livros e textos, e análises críticas, em especial da literatura, do contexto, assim como de situações existenciais. Professores e alunos viram, na prática, novas possibilidades de uma educação que possibilitou aberturas e estratégias que talvez nunca teriam sido pensadas.  Este texto relata algumas experiências obtidas durante a fase da pandemia em cursos de graduação e pós-graduação stricto sensu. Nessa medida, em nossas experiências, procurou-se ressaltar a importância de caracterizar o período, assim como buscou-se leituras que, de alguma maneira, discutissem o contexto pelo qual estamos passando. Buscou-se, inclusive, a discussão de situações existenciais propostas pela literatura de Proust, Beckett, Marco Lucchesi, Emil Cioran e outros autores importantes. Conclui-se que houve uma recepção muito amistosa por parte dos estudantes que proporcionaram uma visão mais crítica em relação ao ensino remoto e que as artes, assim como a literatura podem ser instrumentos ferozes em busca de novos valores humanos e contextuais.
AULAS DE VIOLÃO ON-LINE: UM RELATO DE EXPERIÊNCIA SOBRE O ENSINO DE INSTRUMENTO DURANTE A PANDEMIA DE COVID-19
Authors: Schossler Mariele
Published: April 2021

O presente texto é um relato das experiências vividas com aulas de violão por videochamada com três alunos, durante o período de distanciamento social por conta da pandemia de Covid-19 no ano de 2020. A aluna, de 10 anos, e os alunos, de 11 e 13 anos, tiveram aulas individuais comigo de setembro a dezembro deste ano, culminando em um recital de natal, inteiramente on-line. Acompanhando o desenvolvimento dos alunos, descobrimos como utilizar as ferramentas digitais para um melhor aproveitamento no aprendizado do instrumento. Conseguimos contornar desafios, como o atraso entre o envio e a recepção de áudio e vídeo nas reuniões no Google Meet, para permitir a prática síncrona e a gravação dos alunos para o recital.
A MÁSCARA E A GATA: ARTE NA QUARENTENA DE UM PRÉ-ADOLESCENTE
Authors: Doll Johannes , Fröhlich Cláudia Bechara
Published: April 2021

O que a escola e as artes podem fazer nesta situação de distanciamento social e de ensino a distância? É desafiante para as e os professores e, muitas vezes, fica difícil ter uma noção dos efeitos na vida dos e das estudantes. O relato de produções artísticas de um menino de 11 anos, no 6º ano da escola, pode mostrar como elementos do ensino à distância podem provocar e inspirar o mundo imaginário de jovens. O relato mostra, também, que as condições familiares, bem como a compreensão e a estimulação de caminhadas próprias, são fatores importantes para uma produção artística que contribua para o processo de subjetivação.

TO THE 100th ANNIVERSARY OF THE DEPARTMENT OF THE HUMAN ANATOMY OF THE OMSK STATE MEDICAL UNIVERSITY
Authors: Putalova Irina N. , Suslo Aleksandr P. , Shirochenko Svetlana N. , Slavnov Andrey A.
Published: April 2021

The article describes the history of the Department of Human Anatomy at Omsk State Medical University. At the stages of its formation, the continuity, preservation and enhancement of the traditions of the Russian anatomical school are traced. It is noted that in the training of doctors, the staff of the department adheres to a reasonable combination of traditional anatomical methods with innovations and modernization of the educational process. Brief biographies, scientific and pedagogical staffs of the heads of the department are presented and the team of teachers at each stage during the centuries-old history is characterized. In teaching of students, the department implements onto- and phylogenetic principles, a functional approach, the doctrine of individual variability, and the clinical orientation of teaching. The main scientific areas of research of the department staff are the study of individual, age-related topographic and projection features of organs and other anatomical structures on the skeleton and skin of the human body, experimental and clinical lymphology and angiology, and the development of the museum.
RONTGEN-MORPHOMETRIC DATA TO THE CORRELATION OF THE PHALANXES LENGTH WITH A LENGTH OF HUMAN HANDS FINGERS
Authors: Ermolenko Aleksandr S.
Published: April 2021

Data on the anatomical variability of the phalanges and fingers of the hand are needed to expand biometric databases in robotics, prosthetics, and forensic medicine. The aim of the study was to study the X-ray morphometric variability of the length of individual phalanges of the fingers of the hand, their relationship with the length of the fingers. By the method of morphometry, the lengths of individual phalanges and fingers of the hands were determined on 100 certified radiographs of the hands of persons of the second mature age (50 men and 50 women), and a correlation was established between the length of the phalanges and fingers. To identify the statistical relationship between quantitative characteristics, the parametric Pearson correlation coefficient was used. The relationship between quantitative indicators was assessed using multiple regression analysis. Classification and grouping were carried out using cluster analysis by the complete connection method, the Euclidean distance served as a measure of the relationship. The variability in the length of the phalanges and fingers increases towards the ulnar edge. The X-ray morphometric length of individual phalanges and fingers is characterized, regardless of gender, by regular formulas of variability: the length of the proximal phalanges is III>IV>II>V>I, the length of the middle phalanges is III>IV>II>V, the length of the distal phalanges is I>IV> III>II>V, finger length - III>IV>II>V>I. The degree of dependence of the length of the fingers on the length of the phalanges in both men and women decreases in the distal direction in the longitudinal axis and the ulnar edge in the transverse axis of the hand. As a result of cluster analysis, the organization of the objects of study was established depending on the degree of correlations of their length: groups of proximal phalanges of II-IV and I, V fingers, groups of middle phalanges of III-IV and II-V fingers, distal phalanges and fingers are organized somewhat more complexly - groups III -IV, II, V fingers and group I fingers. The data obtained can be used in the development of innovative anatomically grounded anthropomorphic robotic manipulators, in anthropological reconstructions, and in identification in forensic practice.

Authors: Cerqueira Gabriela Alves de , Souza Lais Sampaio , Soares Gomes Rafael , Marchi Giselle Maria , Mathias Paula
Published: April 2021

Aim: This study evaluated the water sorption and solubility of a light-cured resin cement, under four thicknesses and four opacities of a lithium disilicate ceramic, also considering three light-emitting diode (LED) units. Methods: A total of 288 specimens of a resin cement (AllCem Veneer Trans – FGM) were prepared, 96 samples were light-cured by each of the three light curing units (Valo – Ultradent / Radii-Cal – SDI / Bluephase II – Ivoclar Vivadent), divided into 16 experimental conditions, according to the opacities of the ceramic: High Opacity (HO), Medium Opacity (MO), Low Translucency (LT), High Translucency (HT), and thicknesses (0.3, 0.8, 1.5, and 2.0 mm) (n = 6). The specimens were weighed at three different times: Mass M1 (after making the specimens), M2 (after 7 days of storage in water), and M3 (after dissection cycle), for calculating water sorption and solubility. Results: The higher thickness of the ceramic (2.0 mm) significantly increased the values of water sorption (44.0± 4.0) and solubility (7.8±0.6), compared to lower thicknesses. Also, the ceramic of higher opacity (HO) generated the highest values of sorption and solubility when compared to the other opacities, regardless of the thickness tested (ANOVA-3 factors / Tukey’s test, α = 0.05). There was no influence of light curing units. Conclusion: Higher thicknesses and opacities of the ceramic increased the water sorption and solubility of the tested light-cured resin cement.

Aim: This study aimed to compare the microbiological potential and gustatory perception of essential oils (EO) mouthrinses containing and not containing alcohol. Methods: Twenty healthy adult volunteers rinsed with 10mL of the following test solutions: EO with alcohol, EO without alcohol, or a control solution (saline solution with mint essence). A washout period of at least seven days was adopted after a single-use protocol of the respective solution. All participants used all three tested substances. Antimicrobial potential was assessed by counting salivary total viable bacteria both before and after each rinse. Gustatory perception was evaluated using the Visual Analogue Scale (VAS). Multiple comparisons were performed with the Wilcoxon test, using Bonferroni correction. Results: Both EO solutions presented a higher antimicrobial potential in comparison to the control solution (p<0.017). However, no significant difference in antimicrobial potential was observed between EO containing or not containing alcohol (p=0.218). VAS of EO with alcohol (median: 2.7) was similar to control solution (median: 1.6) (p=0.287). A better gustatory perception was observed of the EO without alcohol (median 7.6) when compared to the control solution (p<0.0001). When EO groups were compared, EO without alcohol also demonstrated a significantly better gustatory perception (p=0.001). Conclusion: Mouthrinse containing EO without alcohol presented a better taste perception when compared to the EO with alcohol, but no difference was observed in the antimicrobial potential of both EO solutions after a single rinse protocol.
Variação diacrônica do grau de transparência linguística do português brasileiro
Authors: Guerra Alessandra Regina
Published: April 2021

Neste artigo, analisamos a variação diacrônica do grau de transparência linguística do português brasileiro, focalizando o sistema de expressão pronominal e desinencial do argumento-sujeito de primeira e segunda pessoas. Argumentamos que a transparência desse sistema é afetada diacronicamente por três mudanças em curso na língua: aumento da frequência de expressão pronominal do argumento-sujeito, aumento da frequência de uso do pronome você em detrimento de tu, aumento da frequência de uso da forma pronominal a gente em prejuízo de nós. Além disso, fornecemos dados acerca da primeira dessas mudanças e apresentamos um cálculo quantitativo que indica o papel dessa mudança como fator de diminuição do grau de transparência da língua.

Authors: Guimarães Thiago  Santos , Massena Elisa Prestes , Siqueira Maxwell Roger da Purificação
Published: April 2021

Ao longo dos últimos anos, têm ocorrido mudanças significativas no que se refere ao âmbito das instituições de ensino superior no país, e isto tem provocado discussões acerca da busca por atender as novas necessidades formativas e os desafios apresentados neste nível de ensino. Assim, cabe ressaltar a importância da compreensão do papel do professor universitário e a necessidade que este possui de modificar suas ações docentes em tempos de constantes avanços sociais e tecnológicos. Nesse sentido, o objetivo deste estudo foi analisar as percepções desses formadores de professores acerca de suas práticas pedagógicas. Neste estudo, serão apresentados os resultados provenientes de um questionário semiestruturado com seis questões, respondido por quatorze formadores de professores dos cursos de licenciatura em Química, Física e Biologia de uma universidade pública do país, sendo a análise dos dados realizada através da Análise Textual Discursiva. Os resultados indicam que os formadores de professores que conseguem fazer relação direta entre a teoria e as práticas pedagógicas possuem comprometimento com a profissão docente e buscam novas estratégias para utilizar em suas aulas, o que visa facilitar e incentivar o processo de ensino e aprendizagem dos licenciandos. Para isso, acreditamos que são necessários os esforços e compromissos tanto dos formadores de professores quanto das instituições de ensino superior, numa integração em busca da melhoria do ensino universitário.
Políticas públicas de cotas para ingresso no ensino superior
Authors: Rosa Claudia Cristina Borba de Barros da , Martins Suely Aparecida
Published: April 2021

Neste artigo tratamos da implementação das políticas públicas de ações afirmativas de ingresso no ensino superior. Essas políticas são alvo de grandes discussões na sociedade acadêmica, bem como na sociedade em geral, especialmente a partir de anos de 2000 quando várias universidades públicas passaram a adotar políticas de cotas. Por sua vez, políticas como o REUNI e a aprovação e promulgação da Lei Federal Nº12.711/2012, constituíram-se como ações importantes para o acesso das classes populares as universidades públicas. Assim, analisamos como se deu a implementação das políticas públicas de ações afirmativas na Universidade Tecnológica Federal do Paraná (UTFPR) – tendo como lócus para a realização do estudo o Câmpus de Francisco Beltrão, considerando especialmente o período de 2008 a 2016. Buscamos compreender como foi organizada essa implementação, quais as dificuldades enfrentadas e as soluções encontradas pelos agentes responsáveis pela efetivação da política na universidade. A pesquisa, de caráter qualitativo, baseou-se na análise de documentos e de entrevistas realizadas com 07 servidores da instituição. Ponderamos que embora sejam necessários ajustes na legislação, principalmente no que se refere ao investimento público em políticas públicas de assistência estudantil, recursos humanos e materiais, o acesso ao ensino superior de uma parcela da população que antes não chegava a este nível de ensino, tem sido garantido. Todavia, passos precisam ser dados em relação a permanência e sucesso desses sujeitos.
Gabrielly, diferenças e educação das trans no Oeste Paulista
Authors: Silva Fernando Guimarães Oliveira da , Maio Eliane Rose
Published: April 2021

Gabrielly poderia passar despercebida, mas inscreveu sua história na brasilidade dos estudos sobre o universo trans. Com a beleza peculiar de sua feminilidade, objetivamos trazer questões pertinentes à filosofia da educação. Propomos acessar suas memórias de escolarização cujo itinerário formativo ocorreu, segundo Gabrielly em dois momentos, em unidades públicas educacionais do Oeste Paulista. Ancoramos a abordagem metodológica nos estudos pós-críticos em educação por se tratar de uma temática cara aos estudos da diferença articulada com o uso da educação como um projeto de ampliação da capacidade de sobrevivência para mulheres trans, cujos dados, cruelmente, apontam que representam um grupo fadado às políticas de morte. Como instrumento de coleta das memórias, utilizamos a arqueologia foucaultiana para compreender a construção feminina de Gabrielly. Não se apontou conclusões, mas inquietações filosóficas promotoras de novas práticas educacionais mais preocupadas com a responsabilidade, preservação e comoção pelas vidas trans cujo reflexo disso, afeta o ambiente escolar como um lugar de preocupação ético-política. Portanto, propomos a possibilidade de ruptura com os quadros de precarização de vidas travestis, transexuais e transgêneros.
Chance Debugged
Authors: Dohrn Daniel
Published: April 2021

A ‘Big Bad Bug’ threatens Lewis’s Humean metaphysics of chance (Lewis 1986a, p. XIV); his Principal Principle provides an intuitive link between chance and credence. Yet on the one hand, certain future developments are incompatible with the true theory of chance, but on the other hand, such future developments have a positive chance to occur. The combination of these two claims with the Principal Principle leads to inconsistent credences. I present a Humean solution to the Bug: chances are relative to a limited perspective. The perspective comprises facts available as evidence to an ideal cognizer at a point in space-time. As a consequence, the same future event can have different chances of occurring provided the perspective is different. I show how this dissolves the Bug.

Globalization of Economy: qualis es et quo vadis?
Authors: Pan'kov V.
Published: April 2021

In a long historical perspective, the globalization of the economy is, no doubt, the future of the mankind. However, we should not overlook the contradiction that has dramatically intensified as a result of the 2008-2009 recession. This is the contradiction between globalization as an objective process with mostly positive effects and its model that is being implemented today (namely, the policy of globalization). Furthermore, we can propose a number of important arguments in favor of a statement that at the current state of affairs the globalization has exhausted itself. Nobody can exclude a short-term braking down of the globalization progress nor even a U-turn, albeit temporary, to a de-globalization. Under unfavorable circumstances such a reverse movement can cover the entire period up to 2020. The author states that transnational corporations are the main subject of the world economy which will the most actively oppose such a development.
Contemporary Regionalism
Authors: Spartak A.
Published: April 2021

The new trends in the field of regional economic integration, as well as the changing trade and the political configuration of the global economy cannot but affect integration processes within the Commonwealth of Independent States (CIS). Russia seems to be somewhat late with the project of a “hard” regional integration involving supranational control formats. The globalization dictates economic feasibility of an open trade and this is increasingly becoming a significant centrifugal factor. Our main task now is to complete as soon as possible the institutional phase of the Customs Union and the Common Economic Space between Russia, Belarus and Kazakhstan. Only after accomplishment of this integration project we can start to position it as a full-fledged subject of the world trade policy. Simultaneously, we must emphasize our interest in expanding and deepening the cooperation with the third countries and their groupings, including the RTS format. The same consideration prompts us to be extremely careful and reserved concerning the prospects of enlarging the Customs Union. The only possible Commonwealth-wide integration project format can be “soft” integration. This supposes the establishment of a multilateral free trade area (MFTA) with the elements contained within the modern economic integration agreements.
New Projects of Asian-Pacific Integration
Authors: Sevast'yanov S.
Published: April 2021

Since late 80-s of XX century active integration processes are undergoing in the Asia-Pacific region. Asian countries are trying to minimize the negative effects of the shocking changes in the system of international relations and of the global or regional economic crises. United States are quite actively involved in the regional integration. By using the “old” and creating “new” associations USA try to oppose the growing influence of China here. Russia, for its part, is also looking for the effective ways to connect to the Asian integration projects that can improve the socio-economic situation of the population of the Far East and will enable us to make a significant contribution to the development of economic cooperation in the Asia-Pacific region.

The article examines the trade in certain branches of engineering products in 1990-2000, the influence of the global crisis on international trade, as well as the balance of payments problems of major countries and regions of the world.
Interests of Russia and US in Central Asia: Prospects of Possible Cooperation
Authors: Dorofeev S.
Published: April 2021

The main idea of this article is to identify the strategic interests of Russia and the United States and their feasibility taking into account the operational institutions and historical experience of development in the Central Asia. Using in this analysis the concept of strategic interest the author comes to the following conclusions. Firstly, realization of the long-term interests is prevented by the will to obtain short-term benefits. Secondly, a discrepancy between the strategic interest and the “national interest” should be underlined since the latter has a too broad meaning and is often perceived only in the context of the public interest.

Russian in World and in Sphere of Scientific Knowledge
Authors: Cheshkov M.
Published: April 2021

In this theoretical work Russia is seen through a prism of the situation that emerged in late 20th and early 21st centuries. The Russian society enters into a process of transformation of the domestic perception of the world into an exploration of the world. According to the author, the main problem of the Russia’s exploration of the world will be solved through the process of connecting the world’s universe and the human’s universe not only in Russia but in a global context. A broad vision of the past and the future of the Russian science began to form in early 90s of XX century.
Shall We See «Demographic Peace»?
Authors: Lukin A.
Published: April 2021

The author discusses the relationships between the demographic processes taking place in the leading countries of the world, particularly the United States, Russia, India, countries in North-East Asia, and the prospects of the evolution of their domestic and foreign policies. The principal features of the great powers’ evolution are picked out, including steadily ageing of the population, slowing down of economic growth and even its absolute reduction. In the author’s view, in the future this will reduce the material possibilities and socio-psychological inclination of aging states to pursue power politics. This may contribute to the creation of preconditions for a “demographic peace”.

Small Symmetrical Deformation of Thin Torus with Circular Cross-Section
Authors: Sun Bohua
Published: April 2021

By introducing a variable transformation $\xi=\frac{1}{2}(\sin \theta+1)$, a complex-form ordinary differential equation (ODE) for the small symmetrical deformation of an elastic torus is successfully transformed into the well-known Heun's ODE, whose exact solution is obtained in terms of Heun's functions. To overcome the computational difficulties of the complex-form ODE in dealing with boundary conditions, a real-form ODE system is proposed. A general code of numerical solution of the real-form ODE is written by using Maple. Some numerical studies are carried out and verified by both finite element analysis and H. Reissner's formulation. Our investigations show that both deformation and stress response of an elastic torus are sensitive to the radius ratio, and suggest that the analysis of a torus should be done by using the bending theory of a shell.
High Temperature and High Hydrostatic Pressure Cultivation, Transfer, and Filtration Systems for Investigating Deep Marine Microorganisms
Authors: Oliver Gina Carole , Cario Anaïs , Rogers Karyn Lynne
Published: April 2021

High temperatures (HT) and high hydrostatic pressures (HHP) are characteristic of deep-sea hydrothermal vents and other deep crustal settings. These environments host vast and diverse microbial populations, yet only a small fraction of those populations have been successfully cultured. This is due, in part, to the difficulty of sampling while maintaining these in situ conditions and also replicating those high-temperature and high-pressure conditions in the laboratory. In an effort to facilitate more HT-HHP cultivation, we present two HT-HHP batch culture incubation systems for cultivating deep-sea vent and subsurface (hyper)thermophilic microorganisms. One HT-HHP system can be used for batch cultivation up to 110 MPa and 121°C, and requires sample decompression during subsampling. The second HT-HHP system can be used to culture microorganisms up to 100 MPa and 160°C with variable-volume, pressure-retaining vessels that negate whole-sample decompression during subsampling. Here, we describe how to build cost effective heating systems for these two types of high-pressure vessels, as well as the protocols for HT-HHP microbial batch cultivation in both systems. Additionally, we demonstrate HHP transfer between the variable-volume vessels, which has utility in sampling and enrichment without decompression, laboratory isolation experiments, as well as HHP filtration.
A Review of COVID-19 Vaccines: What Needs to Be Known and Its Expected Effect on the Human Population?

Published: April 2021

The COVID-19 pandemic is a devastating blow to the entire world community and changes the order of human life. All efforts and strategies are being carried out to contain and reduce the spread of the SARS-COV-2 virus, both by tightening the health protocol and using vaccines to the public. Currently, several vaccines are available and have passed phase 3 clinical trials, such as vector vaccines (Gamaleya Sputnik V Russia, University of Oxford/AstraZeneca, CanSino, and Janssen Pharmaceutical Companies), mRNA-based vaccines (Moderna/BioNTech/Fosun Pharma/Pfizer), inactivated vaccines (SinoVac and SinoPharm from China, Covaxin from Bharat Biotech India), and adjuvanted recombinant protein nanoparticles (Novavax from the USA) are expected to be able to suppress the spread of the virus and produce a minimum of 70 percent herd-immunity in a population. Each vaccine's efficacy varies from the lowest, namely the Sinovac vaccine (CoronaVac) 50% to the highest the Novavax vaccine (NVX-Cov2373) 96% effectivity value. Moreover, further rigorous research is still being carried out for the development of an effective and efficient vaccine.
Microplastics (MPs) in Drinking Water: Uses, Sources & Transport
Authors: Bhardwaj Laxmi Kant , Sharma Archana
Published: April 2021

Microplastics (MPs) are small pieces of plastics. They are ubiquitous in the environment and can enter the freshwater environment from surface run-off and wastewater effluent (treated and untreated), industrial effluent, degraded plastic waste, and atmospheric deposition. They are not usually destroyed but convert into one phase to another. They are a source of air pollution, occurring in dust and airborne fibrous particles. Mostly MPs are non-biodegradable while some MPs are biodegradable, which can be decomposed in the presence of ultraviolet (UV) light or by the action of microorganisms. Popular methods: chemical, spectroscopic, and thermo-analytical are available for the determination of the chemical composition and size of plastic particles. This chapter discusses the uses, health hazards, sources, and transport of MPs particles.
Special Issue on Novel Technology of Autonomous Drone
Authors: Suzuki Satoshi , Nonami Kenzo
Published: April 2021

In the past three years, there has been rapid progress in the use of drones in society. Drones, which were previously used only experimentally in various industrial fields, are now being used in earnest in everyday operations. Drones are becoming indispensable tools in several industrial fields, such as surveying, inspection, and agriculture. At the same time, there has also been dramatic progress in autonomous drone technology. With the advancement of image processing, simultaneous localization and mapping (SLAM), and artificial intelligence technologies, many intelligent drones that apply these technologies are being researched. At the same time, our knowledge of multi-rotor helicopters, the main type of drones, has continued to deepen. As the strengths and weaknesses of multi-rotor helicopters have gradually become clearer, drones with alternate structures, such as flapping-wing drones, have come to attract renewed attention. In addition, the range of applications for drones, including passenger drones, has expanded greatly, and research on unprecedented drone operations, as well as research on systems and controls to ensure operational safety, is actively being conducted.

This special issue contains the latest review, research papers, and development reports on autonomous drones classified as follows from the abovementioned perspectives.

· Research on drone airframes and structures

· Research on drone navigation and recognition with a focus on image processing

· Research on advanced drone controls

· Research and development of drone applications

We hope that the readers will actively promote the use of drones in their own research and work, based on the information obtained from this special issue.

In the future one can expect that aerial manipulation will greatly extend the range of possible applications for mobile robotics, especially multirotor UAVs. This can range from inspection and maintenance of previously hard to reach pieces of infrastructure, to search and rescue applications. What kind of manipulator is attached to what position of the airframe is a key point in accomplishing the aerial robot’s function and in the past, various aerial manipulation solutions have been proposed. This review paper gives an overview of the literature on aerial manipulation that have been proposed so far and classifies them by configuration of the workspace and function.

Additionally, new beneficial use (BU) sites were considered along degraded islands adjacent to the GIWW with a threefold objective: increase the quality and quantity of habitat, reduce dredging cost via shorter pump distance, and reduce shoaling in the GIWW through East Matagorda Bay.
Newly Qualified Female Teachers’ Perception of Teaching Practicum as a Component of Initial Teacher Education in South Africa
Authors: Iwu Charmaine Helena
Published: April 2021

This study was undertaken with the aim of understanding how newly qualified female teachers perceive teaching practicum in the South African context. Teaching Practicum is a vital component of the initial teacher education (ITE) programme because it enriches future teachers’ knowledge, skills and abilities towards a lifelong career in the teaching profession. Teachers make valuable contributions to the growth of any nation as they help produce future leaders. It is therefore necessary to have a competent teaching workforce to improve pass rates as well as reduce dropout rates among learners. The study took the qualitative deductive premise making use of semi-structured interviews to collect data from more than 30 novice teachers. Key words, which helped in the identification of themes, were distilled from the responses. A core overall finding of the study point to a mix of experiences - benefits and shortcomings - which not only affect the development of prospective teachers but also have profound implications for both policy enhancement and implementation. Regarding policy enhancement and implementation, it is suggested that universities and schools where novice teachers are posted for teaching practice should have good relations for support advancements. In this case, it is advised that the novice teachers should be exposed to critical mentoring opportunities to allow for clearer understanding of the real classroom scope. This study believes that for this to be fruitful, schools should among others be well-equipped. Suggestions for further research are also flagged.

Generalized Support Vector Machines (GSVMs) model for real-world time series forecasting
Authors: Ahmadi Mehrnaz , Khashei Mehdi
Published: April 2021

Support vector machines (SVMs) are one of the most popular and widely-used approaches in modeling. Various kinds of SVM models have been developed in the literature of prediction and classification in order to cover different purposes. Fuzzy and crisp support vector machines are a well-known branch of modeling approaches that frequently applied for certain and uncertain modeling, respectively. However, each of these models can only be efficiently used in its specified domain and cannot yield appropriate and accurate results if the opposite situations have occurred. While the real-world systems and data sets often contain both certain and uncertain patterns that are complicatedly mixed together and need to be simultaneously modeled. In this paper, a generalized support vector machine (GSVM) is proposed that can simultaneously benefit the unique advantages of certain and uncertain versions of the traditional support vector machines in their own specialized categories. In the proposed model, the underlying data set is first categorized into two classes of certain and uncertain patterns. Then, certain patterns are modeled by a support vector machine, and uncertain patterns are modeled by a fuzzy support vector machine. After that, the function of the relationship, as well as the relative importance of each component, are estimated by another support vector machine, and subsequently, the final forecasts of the proposed model are calculated. Empirical results of wind speed forecasting indicate that the proposed method not only can achieve more accurate results than support vector machines (SVMs) and fuzzy support vector machines (FSVMs) but also can yield better forecasting performance than traditional fuzzy and nonfuzzy single models and traditional preprocessing-based hybrid models of SVMs.

The main objective of this study is to analyse the background and knowledge of Spanish dentists and stomatologists registered in Alicante, Castellón and Valencia, the three provinces that make up the Valencian Community, with regard to forensic dentistry and the current Spanish health legislation and regulations, and to try to quantify the relationship between level of training, specialisation, work experience, position and workplace, and degree of knowledge.An anonymous survey was designed and validated, consisting of thirty-three multiple-choice questions. The survey included questions regarding their professional background and key questions regarding current dental law, forensic science and expertise. Members' level of knowledge of legal and forensic dentistry, health legislation and regulations in the Valencian Community is moderate, with only 63% of the questions answered correctly. Neither their level of education nor work experience correlates significantly with their degree of knowledge. Dentists specialising in General and Aesthetics Dentistry were found to be more knowledgeable about ethical issues. Regarding the workplace, those working as university teachers tended to stand out from the other professionals in terms of legal and ethical knowledge whilst self-employed and employee dentists show a lower level of knowledge than the rest of the sample.The conclusions obtained from this study highlight the need for dentists to complete and update their knowledge of forensic science and current health legislation, as having proper knowledge is a means of avoiding possible legal problems, which not only means better legal protection for the dentist but is also a means of guaranteeing adequate patient care.

Borassus flabellifer leaf extract has been used for rapid biogenic-synthesis of Zinc-Oxide nanoparticles (ZnO-NPs) due to rich source of bioactive compounds. The synthesized ZnO-NPs were preliminarily confirmed by UV-Visible spectroscopy adsorption peak range at 365nm. The XRD (X-ray diffraction) confirm purity of ZnO-NPs that were crystalline in nature. The analysis of FT-IR (Fourier-transform infrared spectroscopy) confirm the presence of following functional group such as alcohol, phenols, carboxylic acids, primary amides, secondary amides, alkyl halide. FE-SEM analysis indicated that ZnO-NPs were in spherical shape, followed by EDX analysis which confirmed the presence of Zn-element. Antimicrobial effect of ZnO-NPs was investigated using different clinical pathogens like bacteria Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Klebsiella Pneumonia, Pseudomonas aeruginosa and fungi Aspergillus flavus, Candida albicans and Penicillium expansum and which confirmed ZnO-NPs efficiency as an antimicrobial agent. Antioxidant activity were ascertained to used for several biomedical applications. The ZnO-NPs was efficiently degraded the environmental toxic dyes (methylene blue and crystal violet) under sunlight. In support of photolight-degradation, the study was progressed to understand the ZnO-dye interaction stability using molecular mechanism and it was showing efficient bonding features in the NPs environment. Overall, this investigation have great potential for being an effective and eco-friendly materials was used in environmental applications.

Published: April 2021

Low brominated diphenyl ethers and brominated dioxins with high toxicity were easily produced in the pyrolysis process of decabromodiphenyl ethers, Based on this, the pyrolysis process of BDE-209 and ZnO was studied by differential thermal gravimetric analysis (DTA-TG), X-ray diffraction (XRD), GC and GC / MS. The results showed that the addition of zinc oxide reduced the activation energy of BDE-209 thermal degradation reaction, thus reducing the thermal degradation temperature of BDE-209; after the addition of zinc oxide, BDE-209 pyrolysis produced more brominated dioxins at 400 ℃ When BDE-209 and ZnO were degraded at 400 ℃ at 2.4:1 (w / W), the degradation rate reached 100% at 2 h. At this time, the relative content of hexabromo- and heptabromo- dioxins was lower, and the relative content of hexabromobenzene and pentabromobenzene was the highest. Combined with Arrhenius formula calculation, soft and hard acid-base theory and XRD product analysis of pyrolysis residue, the mixed pyrolysis mechanism of BDE-209 and zinc oxide was deeply discussed, which provided a theoretical basis for pollution prevention and control of waste printed circuit boards in heat treatment.
