Published: July 2020

Humanity is being affected by the SARS-CoV-2 beta-coronavirus since December 2019. This disease has caused a high mortality rate due to easy contagion in pandemic mundial scale. The transmission occurs from human to human, through respiratory droplets and contact with aerosol-infected surfaces. Anyone carrying the virus that is close (i.e. less than 1 meter) to another person’s eyes, nose or mouth, makes him/her susceptible because of direct contact with the contaminated particles he/she will have (e.g. by touching an infected surface and then touching the eyes, nose or mouth). Due to the risk of exposure to infection, given the forms of contamination by this virus and considering measures to control and protect against infections by health professionals, the Academic Rehabilitation League (LAR), formed by professors and students of the University Center of Americas, produced 400 facial protectors using 3D printing through models composed of polymer filaments, in addition to the acetate films visor and elastics for better fixation, these can be reused and sterilized easily. The masks were distributed free of charge to health professionals in the state of São Paulo, with the purpose of offering greater support, so that they can perform their work safely.

Published: July 2020

In the face of the coronavirus pandemic (COVID-19), in hospital and emergency units, there is low availability of mechanical respirator for patients in need of this support, greatly improving the survival rate. In these situations, there is a need for simpler equipment, easy access, low cost, and fast manufacturing. In this study, a 3D prototype transport respirator was developed using as a model the Takaoka 600 Mini Respirator, national technology from the 1950s. The influence of adjustable parameters of the respirator was evaluated to understand it is functioning: maximum and minimum lung pressure; respirator intake pressure; respiratory rate; inspiratory and expiratory time according to the sensitivity of the mini respirator; and pressure and flow of O₂ line intake. The increase in sensitivity led to an increase in maximum and minimum pulmonary pressure, decreased inspiratory and expiratory time, with margins of 1/1, 1/2, 1/3 inspiratory/expiratory time ratio (I/E ratio). The intake flow of O₂ varied proportionally with the pressure of air intake into the respirator, with its increase leading to an increase in respiratory rate, without major influences on lung pressure and the I/E ratio. The O₂ line intake pressure without major influences on lung pressure, showing and I/E ratio >1 in values below 3.5 kPa x 100. In conclusion, it was possible to obtain a pulmonary ventilator-dependent only on positive O₂ flow, compact and effective for patient transport, and in cases of emergencies with control of maximum pressure and respiratory rate offered to the patient. Among the parameters evaluated for this respirator, an line pressure of O₂ from 3.5 kPa x 100, sensitivity between 3 and 5, a flow of 5 to 15 L/min is recommended.

Authors: De Olivera A , Kreutz C , Martins R
Published: July 2020

The pharmaceuticals as emerging contaminants have become one of the most controversial environmental issues at global scale. Over the years, the presence of antibiotics and anti-inflammatory drugs inside rivers, lakes, and even inside drinking water streams has increased. The wastewater treatment plants (WWTPs) lack the necessary technology to remove concentrations between the range ng/l-mg/l and therefore, the need to develop new methods able to remove contaminants in an effective, low cost and environmental friendly way arises. The present work is focused on studying the potential adsorption capacity of Moringa oleífera (MO) to remove Diclofenac (DCF) and Oxytetracycline (OTC) from wastewater. Through different experiences, it was possible to characterizes the main functional groups of MO and determine the principal responsible of the biosorption process.
A Importância da Didática na Formação Docente
Authors: Bastos Manoel de Jesus
Published: July 2020

Este artigo aborda assuntos relacionados a importância da didática na formação docente na área da pedagogia. Usá-la adequadamente, propiciará um trabalho eficaz e exitoso do professor que além de consumar, com sucesso, as perspectivas previamente propostas, oferecerá um trabalho qualitativo. O trabalho docente deve levar em conta que teoria e prática são caminhos indissociáveis, paralelos e convergentes que norteiam o ensino-aprendizagem no contexto pedagógico. Uma vez que um depende do outro, jamais haveria perfeição na tarefa docente, se não fossem consideradas as suas inter-relações. A aplicabilidade da didática, ora fundamentada na teoria, realizará o papel íntegro do professor no âmbito educacional, com direcionamento ao seu público alvo. É um projeto saindo do papel rumo a sua efetivação. Presumimos que um dentre tantos problemas entranhados no processo do ensino-aprendizagem é a falta da didática, tendo em vista que muitos profissionais da área pedagógica, podem até planejar com excelência, para atender as exigências das secretarias de educação, mas não cumprem integralmente, com o que planejaram.

Authors: Diocesano Kamila Bezerra Fernandes , Costa Aurélio Antonio Ribeiro , Leitão Glauber Moreira
Published: July 2020

El cáncer de mama multifocal/multicéntmo (MF/MC) es una enfermedad que comprende muchos paradigmas en la práctica actual del cáncer de mama. Para combatir la morbilidad y mortalidad de esto la mejor opción es una estrategia terapéutica racional, que debe comenzar con una clara comprensión biológica de la multicentricidad y la multifocalidad, ya que esto se conoce, se puede seguir el tratamiento correcto. Nuestro objetivo era definir el perfil de los pacientes con cáncer de mama multifocal y multicéntrico y evaluar si hay desacuerdo entre los focos tumorales con respecto al receptor hormonal y Her-2. Analizamos retrospectivamente 89 pacientes con cáncer de mama multifocal y multicéntrico invasivo en dos instituciones terciarias en el noreste de Brasil, evaluando el receptor hormonal, Her-2 y ki67 en cada foco tumoral de 25 de estos pacientes, destacando el desacuerdo o no entre ellos, y el tipo y grado histológico, la metástasis de los ganglios linfáticos y la distancia y la edad. De estos pacientes, el 9% presentó heterogeneidad entre los focos tumorales. La proporción de metástasis en ganglio linfático axilar fue del 42% y sólo del 10% para la metástasis distante. El 45% de las mujeres en el estudio tenían grado histológico II o III. Encontramos una prevalencia de 40.5% de Her-2 negativo y 45% del receptor de estrógeno positivo. No hubo diferencia estadísticamente significativa entre el cáncer multifocal y el multicéntrulo. Concluimos que el cáncer de mama MF/MC muestra heterogeneidad entre los focos tumorales en relación con los parámetros biológicos, lo que desempeña un papel crucial en la toma de decisiones sobre el tratamiento y, en consecuencia, sobre la recurrencia del tumor, el pronóstico y la metástasis distante.

Variable Structure Back-Stepping Control of Two-stage Three Phase Grid Connected PV Inverter
Authors: Ullah Nasim , Aziz Al Ahmadi Ahmad
Published: July 2020

This work presents a detailed analysis of a three phase grid tied photovoltaic inverter with variable structure back-stepping control approach. A nonlinear model of the system is derived and presented in rotational frame using the direct quadrature zero transformation (DQ). For the derivation of active and reactive power loops of the inverter, nonlinear back stepping approach is used. Moreover, sliding mode control method is used to derive the inner current loops while for the outer loop a virtual controller is derived using the Lyapunov function. The control loops are implemented in MATLAB/Simulink environment. To test the controller performance, active power variation, DC link voltage variation and reactive power variations are inflicted. The obtained results under the proposed control scheme are compared with boundary layer design based sliding mode controller. From the comparative analysis it is concluded that the proposed controller exhibit superior and robust performance under all test conditions.
Wykorzystanie pojęcia granica w organizacjach – identyfikacja obszarów badawczych
Authors: Jendza Dorota , Wróbel Piotr
Published: July 2020

Celem

artykułu jest identyfikacja dotychczasowej skali i zakresu zastosowania pojęcia

granicy w badaniach organizacji oraz określenie możliwości, które zapewnia

wykorzystanie kategorii granicy do lepszego zrozumienia, jak funkcjonują

organizacje.

W

badaniach dotyczących organizacji kategoria granicy występuje w różnych

kontekstach i obszarach badawczych. Granice w literaturze z zakresu zarządzania

są traktowane jako zewnętrzne i wewnętrzne granice organizacji. W badaniach

analizowane są granice o różnym charakterze: fizycznym, społecznym i mentalnym.

Przedmiotem zainteresowania badaczy są działania podejmowane na granicy

organizacji z otoczeniem, tzw. praca na pograniczu. W ramach badań organizacji wirtualnych

i sieciowych pojawia się koncepcja organizacji bez granic. Psychologowie

organizacji analizują funkcjonowanie granic intrapersonalnych,

interpersonalnych oraz zespołowych.

Granice mają dwoistą

naturę – z jednej strony zapewniają stabilność i bezpieczeństwo, a z drugiej –

współpracę i rozwój. Wykorzystanie różnych znaczeń granicy umożliwia przyjęcie

nowej perspektywy analizy wielu problemów występujących w organizacjach oraz w

relacjach organizacja – otoczenie. Jest to szczególnie cenne w badaniach

interdyscyplinarnych, w szczególności w paradygmacie interpretatywnym.
Intuicyjne rozwiązywanie problemów decyzyjnych z wykorzystaniem teorii systemów szarych
Authors: Nowak Marcin , Borowiec Arkadiusz
Published: July 2020

Proces podejmowania decyzji stanowi jedno z podstawowych zagadnień

teoretycznych w naukach o zarządzaniu. W ostatnich latach szczególną wagę

nadaje się analizie wykorzystania intuicji w tym procesie. Wiele znanych metod

podejmowania decyzji staje się mało użyteczna w przypadku dużej niepewności

informacyjnej egzemplifikowanej trzema cechami: małą ilością informacji, niekompletnością

informacji oraz występowaniem informacji obarczonych błędami, wynikającymi z

subiektywizmu ocen decydentów. Niniejszy artykuł stanowić ma odpowiedź na

zdiagnozowaną niszę. Celem artykułu jest przedstawienie możliwości

wykorzystania Grey Decision-Making Models we wspieraniu decydentów w procesie

wydawania decyzji intuicyjnych. W artykule przedstawiono autorski model klastrowo-decyzyjny

umożliwiający m.in. uwzględnienie w procesie decyzyjnym subiektywnych i niekompletnych

informacji, które mogą zostać wyrażone za pomocą skali lingwistycznej. Model

ten może znaleźć zastosowanie w rozwiązywaniu szeregu problemów zarządczych

obarczonych wysokim poziomem niepewności. W pierwszej części artykułu

przedstawiono podstawy teorii systemów szarych. W drugiej części zaprezentowano

formalny model matematyczny autorskiego szarego modelu decyzyjnego. W trzeciej

części przedstawiono działanie opracowanego modelu decyzyjnego na przykładzie

wyboru normatywnej strategii marketingowej w przykładowym przedsiębiorstwie.
Od zachowań nawykowych do kompulsywnych. 360 stopni wokół smartfonu wśród pokolenia Y – badania empiryczne
Authors: Delińska Liwia , Badowska Sylwia
Published: July 2020

W niniejszym artykule

przedstawiono wyniki badań dotyczących zachowań konsumentów i wykorzystania

produktów mobilnych. Problem naukowy dotyczy określenia w populacji młodych

konsumentów skłonności do uzależnienia od produktu technologicznego? Celem

badania jest identyfikacja wśród przedstawicieli pokolenia Y tendencji do

wykazywania zachowań nawykowych i/lub kompulsywnych na przykładzie smartfona.

Badanie zostało przeprowadzone w 2017 roku za pomocą metody PAPI wśród

konsumentów w wieku 19–24 lata. Zaproponowano autorską skalę konsumenckiej

skłonności do fonoholizmu (KSF). Wyniki sugerują, że smartfon został włączony

do 360-dniowej codziennej aktywności młodych konsumentów. Niektórzy

przedstawiciele pokolenia Y wykazują zachowania nawykowe względem smartfonów,

zaś znaczna liczba badanych przejawia tendencję do zachowań niepożądanych, w

tym kompulsywnych ze względu na skłonność do nadużywania produktu technologicznego.

Wyniki przyczyniają się do pełniejszego

zrozumienia użytkowania produktów technologicznych. 
Poziom akceptacji wartości witalnych i estetycznych a stereotypowe myślenie o starszych pracownikach studentów kierunków ekonomia i zarządzanie
Authors: Szwiec Paweł
Published: July 2020

W organizacjach przyszłości funkcjonujących w

krajach wysoko rozwiniętych powinno znaleźć zatrudnienie coraz więcej starszych

pracowników. To przewidywanie oparte jest na dwóch podstawowych przesłankach.

Po pierwsze, następuje starzenie się wielu społeczeństw. Po drugie, wydłuża się

czas aktywności zawodowej pracowników. Przeszkodę we właściwym funkcjonowaniu i

wykorzystaniu potencjału starszych osób na rynku pracy może stanowić

stereotypowe (z reguły negatywne) myślenie o starszych pracownikach. Jest to

jeden z wielu powodów, dla których warto zrozumieć owo zjawisko, tj.

zidentyfikować jego determinanty. W artykule przedstawiono skutki próby

uchwycenia zależności między wybranymi wartościami osobistymi potencjalnych

decydentów organizacji, a skalą ich stereotypowego myślenia o starszych

pracownikach. Przeprowadzona analiza statystyczna danych uzyskanych w drodze

badań własnych wskazuje, że osoby o niskim poziomie akceptacji dwóch typów

wartości, tj. wartości witalnych i estetycznych przejawiają mniejszą skalę

myślenia stereotypowego o starszych pracownikach, niż osoby o silnej akceptacji

takich wartości. Uzyskane wyniki powinny stanowić bodziec do prowadzenia dalszych

badań w tym zakresie, z uwzględnieniem także innych typów wartości i

właściwości indywidualnych.

Published: July 2020

Communication is the exchanging of information through speaking, writing and signals. It plays an important to our development; it is the dissemination of ideas, and information to persons. Cognition is our mental process in which we acquire knowledge and understanding, and this is done through our thoughts, our experiences, and our senses. Cultural differences involve what people’ believe how they behave, the language they speak, and their practices based on their ethnicity. Cross-cultural differences in cognition can be very effective to certain operations conducted by persons; however, it can also limit us based on our perspective.  To gather information and to understand how culture affects cognition and the way we think, questionnaires, surveys and experiments were used. Questionnaires were administered to tertiary level students, surveys were administered to teachers and experiments were conducted among students from various culture and background. The experiments were centered on visualization, focus and critical thinking. The purpose of this study is to investigate if cultural differences affect the way we think, and this double-dissociation is discussed in terms of implications for different developmental trajectories, with different developmental sub-tasks in the different cultures.
A Review of Socio-Cultural Theory
Authors: Rahmatirad Mahbobeh
Published: July 2020

The purpose of this study is to explore Vygotsky’s contribution to the socio-cultural theory in the field of education in general. Socio-Cultural Theory, based on Vygotskian thought, is a theory about the development of human cognitive and higher mental function. The theory specially emphasizes the integration of social, cultural and biological elements in learning processes and stresses the socio-cultural circumstances’ central role in human’s cognitive development. The study aims to elaborate the impact of social-cultural theory in the leaning. The study also reviews implications and applications of socio-cultural theory in second language acquisition. Moreover, this study also critiques the strong points and weakness points of this theory. There are a number of language learning theories which are introduced by researchers in second language research. These theories are based on research and observation in the field of language learning. B. F Skinner’s theory of behaviorism, Chomsky’s theory of Universal Grammar, Krashen’s five Hypotheses, connectionism and Vygotsky’s socio-cultural theory have changed people’ mind of language learning.
Assisted colonisation trials for the western swamp turtle show that juveniles can grow in cooler and wetter climates
Authors: Bouma A , Kuchling G , Zhai SY , Mitchell N
Published: July 2020

Species with restricted ranges and long generation times are vulnerable to climate change due to limited opportunity to disperse or adapt. Australia’s rarest reptile, the western swamp turtle Pseudemydura umbrina, persists naturally in only one seasonal swamp that holds water in the Austral winter and spring. A marked reduction in winter rainfall in recent decades has shortened the swamp hydroperiod, restricting when turtles are able to feed, grow and reproduce. To mitigate possible future loss of reproductive capacity in the native habitat, assisted colonisation was trialled in 2016 using 35 captive-bred juveniles. Here, we report the outcomes of this 6 mo trial, which compared the growth of turtles released approximately 300 km south of the species’ indigenous range with growth of turtles released at an existing northern translocation site. We showed that growth rates comparable to those at warmer northern translocation sites can be achieved in the south, even in an atypically cool spring as occurred in 2016. Microclimates available to P. umbrina at 2 southern sites were suitable for foraging and growth in late spring and early summer, but juvenile growth at one southern site was significantly better than at the other, likely due to higher prey biomass when water temperatures were suitable for foraging. These early results suggest that introduction of P. umbrina to seasonal wetlands near the south coast of Western Australia could be considered in the immediate future, but further trials are recommended to assess growth and survivorship over longer periods.

GRASSLANDS MARU PHALARIS: PRODUCTIVE AND PERSISTENT IN HILL COUNTRY
Authors: Stevens Dr , Barker J.D.Turner D.J. , Moloney S.
Published: July 2020

A series of trials in Taupo, Wairarapa, and Southland showed that 'Grasslands Maru' phalaris (Phalaris aquatica L.) was well suited to dry hill country. It yielded as well as or better than 'Grasslands Nui' ryegrass and resident swards on an annual basis, being particularly productive in winter, spring and summer. Its spread by rhizomes ensured good swards which remained productive even under set-stocking. Maru suppressed grass grub numbers and continued to produce well under grass grub attack. Responses to fertiliser were good, but withholding fertiliser did not suppress Maru to any greater extent than other pasture grasses. These trials have shown that the seasonal and annual yields of Maru can add flexibility and improved production to hill country farming.

Published: July 2020

Between 1975 and 1982, 320 white clover lines from overseas and New Zealand were evaluated for agronomic potential in southern regions of New Zealand. Two distinct types showed promise. Persistent ecotypes with small leaves and many stolons had an active spring-summer growth pattern suited to the climate of OtagwSouthland Productive types ('Grassland Huia' selections, Mediterranean and French material) had larger leaves with fewer stolons, competed well with grass, were tolerant to leaf diseases but lacked persistence. In 1983, a hybridisation programme combined the desirable features of both persistent and productive types. The best Fl and F2 hybrid lines had a dense morphology, produced 20% greater sprinpsummer yields than the standard Huia and showed good leaf disease tolerance. In 1985, 58 superior plants were selected and polycrossed. The bulk seed from this isolation formed a new we-release cultivar called Southern selection. The selection is being compared with HUM in wards under rotational grazing at Gore. In the 1987/00 year, the selection produced 9% greater spring-summer and annual clover yields than Huia. Improved clover herbage yield was a consequence of rapid stolen development over spring. Grass and total herbage yields from the two clover-based pastures were similar. The trial will be continued in order to obtain long-term production data Keywords: white clover, 'Grasslands Huia'. Southern selection, ryegrass, breeding, productivity, persistence
Response of Yatsyn ryegrass, Matua prairie grass and Wana cocksfoot to phosphorus and potassium
Authors: Clough T.J.
Published: July 2020

At present most pasture fertiliser recommendations are based on the nutrient requirements of perennial ryegrass. The requirements of alternative pasture species are not fully understood and fertiliser is generally applied as for perennial ryegrass. Yatsyn 1 perennial ryegrass, 'Grasslands Matua' prairie grass and 'Grasslands Wana' cocksfoot were grown in sand culture to determine their phosphorus (P) and potassium (K) requirements. Yatsyn and Matna had similar requirements for P and K while Wana required a lower level of K and more P to attain 90% of maximum yield. Magnesium levels in the herbage differed between species and decreased as K applied increased. It is concluded that further studies should be done to more accurately determine the nutrient requirements of alternative pasture species in the field so that accurate and balanced fertiliser applications can be made for alternative pasture species.
