The Correlation of Self-Regulation Theory Constructs and the Incidence of Intradialytic Complications during Hemodialysis
Authors: Arsa Sandi Alfa Wiga , Chairunnisa Miftah
Published: August 2021

Hemodialysis is currently applied as a routine treatment that is widely used by patients with chronic kidney failure, though complications still occur during dialysis. Self-regulation is a kind of theoretical model that represents the effect of perceived disease on behavior and health-related consequences. There is a process of problem representation, coping and appraisal or assessment of coping success involved in self-regulation. This study aimed to determine the correlation between self-regulation theory constructs and the incidence of intradialytic complications during hemodialysis. This was a descriptive analytic study with cross-sectional design. Consecutive sampling resulted in 42 respondents. Logistic regression results obtained disease representation variable with timeline (p=0.122; OR=0.412) and control (p=0.068; OR=0.582) sub-variables; as well as coping variable with Problem-focused (p=0.219; OR=0.912) and emotion-focused (p=0.036; OR=0.3) sub-variables. Intradialytic complications are complex conditions that involve many factors, but the patient's psychological adaptation process also deserves to be considered in developing self-regulation among hemodialysis patients. It is necessary to consider the provision of health education based on the constructs of this self-regulation theory, especially on variables/factors that have a correlation with the incidence of intradialytic complications in order to improve self-management among hemodialysis patients to get a better life.

La Medicina Interna se basa en una atención integral a todas las enfermedades que tienen relación con los pacientes desde los 15 años de edad, tanto en forma ambulatoria, como con hospitalización, excluyendo las que necesiten atención quirúrgica, psiquiátrica o gineco-obstétrica. También incluyen controles en personas sanas dirigidas a la prevención y detección precoz de enfermedades y la promoción de la salud, inmunizaciones (vacunas) y chequeos de salud, entre otros. William Osler, quien es considerado el padre de la Medicina Interna, fue admirado por su capacidad de trabajo, visión clínica de los problemas del enfermo y desarrollo de actividades alrededor del paciente. Él abrió paso a la especialidad en la primera mitad del siglo XX en donde el internista fue reconocido no solo por brindar una atención longitudinal a los pacientes con enfermedades complejas, sino que al mismo tiempo era el consultante de médicos generales debido a su capacidad diagnóstica, convirtiéndose así en el eje fundamental de los hospitales y los servicios ambulatorios de su época. En este libro, Medicina Interna, se actualizan temas de gran importancia para el ejercicio de la profesión. Esta obra puesta hoy a la disposición y consideración de nuestros profesionales, será sin dudas un instrumento de apoyo imprescindible para el trabajo diario y una herramienta de consulta siempre a mano, donde quiera que se encuentren en la práctica de su profesión, incluso en los lugares más recónditos, en el ejercicio de la prevención y atención de la salud del hombre.
A constituição de um novo saber na Educação Matemática: as narrativas como um modo de ruptura teórica e metodológica na formação e pesquisa
Authors: Silva Marinéia Santos , Silva Heloisa
Published: August 2021

Este texto é fruto de uma pesquisa de doutorado (SILVA, 2020) que teve como principal objetivo problematizar os diferentes discursos e modos de operar com as narrativas na Educação Matemática. Tais problematizações partiram de oito narrativas de pesquisadores, líderes de grupos de pesquisa no Brasil, que utilizam o termo “narrativas” em suas perspectivas de estudo e pesquisas na Educação Matemática. A História Oral foi arquitetada durante os movimentos da investigação como metodologia de pesquisa qualitativa potente para abarcar e problematizar os processos de subjetivação de cada colaborador e como cada um atribui significados às suas práticas e visões de mundo. De um modo geral, os resultados da tese acenam para uma multiplicidade de modos de operar as narrativas e, em particular neste texto, as narrativas são problematizadas como um modo de ruptura teórica e metodológica na formação e pesquisa. Neste artigo, apresentamos e discutimos como esse saber das narrativas passou a ser objeto de estudo na Educação Matemática, a partir das vivências de alguns educadores matemáticos que tematizam esse saber na área. A tessitura de discussões está apoiada em aspectos dos métodos arqueológico e genealógico de Michel Foucault.
Dos quadros de Dunton às cartas de Parker: números e cálculos à vista (São Paulo, 1890-1910)
Authors: Oliveira Marcus Aldenisson , Valdemarin Vera Teresa
Published: August 2021

A partir de um conjunto de documentos que expressam estratégias políticas e pedagógicas dos republicanos paulistas na institucionalização da escola pública, objetivou-se identificar as orientações dadas aos professores para ensinar Aritmética no curso primário e analisar a organização didática dos seus saberes focalizando, de modo particular, o uso dos Quadros americanos (de Dunton) e das Cartas de Parker como materiais auxiliares para o ensino do número e do cálculo. No bojo da renovação pedagógica almejada pela escola graduada paulista, a crença na eficácia do método intuitivo marcou a cultura escolar das décadas finais do século XIX e iniciais do século XX. A partir do método intuitivo, a criança aprenderia Aritmética sem a necessidade de pré-requisitos provenientes de outros saberes, bastando dispor ao alcance dos seus sentidos alguns objetos/pontos/traços para serem percebidos, contados e calculados. A análise da renovação no ensino da Aritmética, aqui particularizada, elucida e exemplifica a estreita articulação estabelecida entre método de ensino, materiais didáticos próprios ao seu desenvolvimento e mudanças na epistemologia dos saberes escolares.

Este texto aponta contribuições de disciplinas relacionadas à Psicologia, do Curso Pedagógico do Ginásio de Jequié, na formação pedagógica das normalistas para o ensino de Matemática, no período de 1954 a 1966. Buscando responder de que forma as disciplinas relacionadas à Psicologia do curso pesquisado colaboraram para a formação pedagógica das normalistas para o ensino de Matemática, a pesquisa pautou-se na história cultural, fundamentada em Chartier (1991, 2002); nas noções de cultura escolar e disciplina escolar, de Julia (2001) e Chervel (1990), respectivamente; e nas categorias saberes a ensinar e saberes para ensinar, de Hofstetter e Schneuwly (2017). Considerando os saberes para a formação de professores, foram analisados conteúdos das disciplinas relacionadas à Psicologia e se concluiu terem sido elas fundamentais para a formação das normalistas, preparando-as para atuar tanto em Matemática como nas demais disciplinas. No contexto geral das disciplinas, contribuíram mediante o ideário da Escola Nova com conhecimentos básicos, concepções de infância e métodos educativos. Quanto ao ensino de Matemática, a disciplina Psicologia facultou uma abordagem de aspectos ligados à didática e à cognição e priorizou os saberes para ensinar, se ocupando da psicologia da matemática, da psicologia da aritmética, da psicologia da tabuada, dentre outros.
A Escola Família Agrícola (EFA) Itapirema de Ji-Paraná (RO) e o ensino de Matemática (1991-2018): uma perspectiva histórica
Authors: Dias Jucielma Rodrigues de Lima , Gouveia Neto Sérgio Candido de
Published: August 2021

Este artigo tem como objetivo construir uma história do ensino de Matemática da EFA Itapirema de Ji-Paraná/RO (1991 – 2018). Como a EFA possui uma metodologia de ensino específica, a Pedagogia da Alternância, é necessário entendê-la, bem como seus instrumentos, pois o ensino de Matemática perpassa por eles. Por se tratar de uma pesquisa histórica, utilizaremos a perspectiva de Bloch (2001) em relação à crítica ao documento, de Halbwachs (2004) com o conceito de memória coletiva e de Le Goff (1990), que considera o conceito de memória como fundamental para a pesquisa histórica, juntamente com os escritos de Gimonet (2007) sobre a Pedagogia da Alternância. No desenvolvimento, foram analisadas as transcrições das entrevistas realizadas com dois professores da disciplina que atuaram na escola desde o início, bem como a análise de outros documentos. Os resultados nos mostraram que o ensino de Matemática da escola se dá por meio de um ensino pautado nas relações cotidianas que são retiradas do caderno da alternância, e a vivência da alternância é de suma importância nesse processo.

Authors: Ситдиков Рустэм Наилевич , Вайчулис Елена Алексеевна
Published: August 2021

Соблюдение требований законодательства Российской Федерации и международных соглашений по охране окружающей среды является обязательным при выполнении всех видов строительно-монтажных работ. Организация эффективного производственного (строительного) контроля за соблюдением требований экологической безопасности позволяет минимизировать риски аварий, инцидентов, отказов оборудования, избежать штрафов, сверхлимитных платежей, репутационных потерь. С целью снижения природоохранных нарушений при проведении работ на объектах строительства предложено применение риск-ориентированного подхода в рамках производственного контроля. Для расчета показателя риска авторами проведен анализ нарушений природоохранного законодательства, определены значимые расчетные параметры, разработаны формы проверочных листов контроля соблюдения требований природоохранного законодательства подрядной организацией при проведении строительных работ. Апробация риск-ориентированного подхода осуществлена на объектах технического перевооружения организаций системы «Транснефть». По результатам апробации даны предложения для внесения изменений в нормативную документацию ПАО «Транснефть».

Compliance with the Russian Federation law and international agreements on environmental protection is mandatory when performing all types of construction and installation work. Organization of effective production (construction) control over compliance with environmental safety requirements allows minimizing the risks of accidents, incidents, equipment failures, fines, extrabudgetary payments, and reputation losses. In order to reduce environmental violations during construction site works, it is proposed to apply a risk-based approach within the production control framework. In order to calculate the risk indicator, the authors analyzed violations of environmental legislation, identified significant design parameters, developed checklists for monitoring compliance with environmental laws by the contractor during construction works. Appraisal of the risk-based approach was conducted at the Transneft system entities’ retrofitting facilities. Based on the results of appraisal, proposals for amending the Transneft PJSC regulatory documents were made.

Published: August 2021

Нормирование качества трубной продукции является ключевым инструментом, влияющим на системную надежность, безопасность и эффективность функционирования объектов магистральных трубопроводов. В статье рассмотрены особенности оценки соответствия стальных труб, предназначенных для строительства, ремонта и реконструкции линейной части нефте- и нефтепродуктопроводов. Проведен сравнительный анализ технических требований к трубной продукции, установленных отраслевыми нормативными документами, международными и национальными стандартами. Выделены проблемные вопросы, связанные с оценкой соответствия труб, применяемых на объектах нефтепроводного транспорта. Отмечено, что проблема повышения качества труб актуальна как для операторов магистральных трубопроводов, так и для заводов - изготовителей трубной продукции. На основе практического опыта определено, что наилучшие результаты в области контроля и повышения качества труб обеспечивает реализация комплекса мероприятий, сочетающего «классическую» процедуру оценки соответствия (сертификации) с методической базой, позволяющей на основе статистических данных об отказах и браке в условиях эксплуатации трубной продукции эффективно решать задачи по управлению ее качеством.

Standardization of the pipe products quality is a key tool affecting system reliability, safety, and efficiency of operation of main pipeline facilities. The article discusses the features of conformity assessment of steel pipes intended for the construction, repair, and reconstruction of linear sections of oil and oil product pipelines. A comparative analysis of the technical requirements for pipe products established by industry regulations, international, and national standards has been conducted. The issues related to the conformity assessment of pipes used at oil pipeline transport facilities are highlighted. It is noted that the issue of improving the quality of pipes is relevant both for operators of main pipelines and for manufacturers of pipe products. Based on practical experience, it has been determined that the best results in monitoring and improving the quality of pipes are ensured by implementation of a set of measures that combines the traditional conformity assessment (certification) procedure and a methodological base that allows to effectively solve problems of managing their quality based on statistical data on faults and defects in the operating conditions of pipe products.

Published: August 2021

O modelo mecanicista, baseado no pensamento linear, vem produzindo uma realidade insustentável, doentia e desumana. Torna-se urgente a reavaliação das cadeias de produção, à luz do pensamento sistêmico. Necessários são a compreensão dos processos envolvidos nos sistemas produtivos e o entendimento das inter-relações existentes nos mesmos. Assim, o método de Avaliação do Ciclo de Vida se apresenta como técnica eficaz para avaliar os impactos ambientais provocados pelo sistema. Igualmente, o contexto do território no qual o mesmo está inserido deve ser considerado. Diante disto, este estudo buscou analisar a produção do licor de macaúba no território do Serro (MG). O extrativismo da macaúba (Acrocomia aculeata), palmeira perene da região, é praticado no território, apresentando potencial para criação, sob a perspectiva do Design Sistêmico, de atividades interconectadas e a implantação de um macrossistema. A análise do Inventário de Ciclo de Vida permitiu observar impacto potencial, relativo ao aquecimento global, ligado à emissão de CO2 devida aos transportes – embora possa haver sequestro de parte dessas emissões, pelas próprias palmeiras. Os pontos problemáticos observados podem ser, no entanto, considerados como ‘alavancas para mudanças’, permitindo a identificação de novas atividades produtivas, gerando trabalho e renda para a comunidade.

Genotoxic activity of betel nut on germinal cell in Sarcoma 180 ascites tumour bearing male mice
Authors: Sudipta Chowdhury  , Samarendra Nath Banerjee
Published: August 2021

The genotoxicity of the ethanolic extract of betel nut was evaluated using sarcoma 180 tumour bearing mouse considering sperm motility, sperm viability, biochemical estimation of fructose in seminal fluid and sperm head morphology assays. Sperm head morphology was studied by H-E staining and Toluidine blue staining method. But Toluidine blue staining method is a reliable method to evaluate the DNA damage of sperms. Ethanolic BNE (betel nut extract) can suppress the percentage of sperm motility, sperm viability and seminal fructose level. In addition, it can also enhance the percentage of DNA damaged sperms. Moreover, histological sections of testes have been studied in control and BNE treated sarcoma 180 tumour bearing mice to highlight the potential toxic effect of BNE. The significant decreasing rate of seminal fructose concentration, sperm motility as well as viability and increasing rate of sperm head abnormality in different doses of treated series may be as a result of different toxic alkaloid ingredients present in BNE. Therefore, the results showed the potential of the BNE to induce different types of germ cell abnormalities in tumour bearing male mice.

Published: August 2021

On 31st December 2019, the World Health Organization (WHO) was notified of a cluster of cases of pneumonia of unknown cause detected in the Wuhan, Hubei Province of China which eventually was named to be the Corona virus disease. In response to the rapid spread of the virus, WHO declared it a public health emergency of international concern (PHEIC) on 30th January, 2020. As per the quest to recharge the COVID-19 response power, there is seemingly little or no tangible plans to help permanently reorient Africa’s health care system. In the wake of widespread vaccine nationalism, donor countries continue to secure large quantities of vaccines from developers and manufacturers, causing global disparity in access to COVID-19 vaccines.

High Hydrostatic Pressure Processing (HPP) has gained more attention in the fruit and vegetable industry in recent years. In this study, the optimal acidification parameters (citric acid alone and combination with ascorbic acid at the pH range 3.0 to 4.5) were determined and the effect of HPP conditions (pressures 250- 450 MPa and exposure times 1-5 min) on acidified liquorice root sherbet (ALRS) were investigated. Results showed that acidification of LRS by only citric acid had higher aroma and flavor scores. HP treatments were effective to reduce the yeast and mould (YM) count, total coliforms (TC), and inoculated pathogens (Escherichia coli ATCC 25922 and Salmonella Typhimurium ATCC 14028) in ALRS. Although acidification of LRS achieved a significant reduction in glycyrrhizic acid (GA) content, further treatment by HPP did not affect pH, the contents of total phenolic, total soluble solids, flavonoid, and GA or the antioxidant capacity of ALRS. Our results suggests that acidification and HPP treatments could be used to increase the consumer acceptability and extend the shelf life of LRS.
Get More Eyes on Your Work: Visual Approaches for Dissemination and Translation of Education Research
Authors: Rodrigues Jessica
Published: August 2021

This article suggests two approaches for sharing education research based on a model of research dissemination for Twitter pioneered by the medical community. The first approach is the visual abstract that reflects a visual summary of a study’s textual abstract. Evidence demonstrates that compared with a text-alone approach, the visual abstract yields eight times as many shares on Twitter and three times as many people clicking to access the full article. The second strategy is the translational visual abstract that is designed for sharing education research with nonscientific audiences. I provide a general overview of using Twitter for research dissemination, describe each visual approach and share step-by-step design guidelines, offer recommendations for using these visuals for dissemination purposes, and conclude with future directions for investigating the effectiveness of visual abstracts and translational visual abstracts for communicating education research.
Ultrafine particulate matter in methane-air premixed flames with oxygen enrichment
Authors: Dasappa Shruthi , Camacho Joaquin
Published: August 2021

A complementary computational and experimental study is carried out on the formation of ultrafine particulate matter in premixed laminar methane air flames. Specifically, soot formation is examined in premixed stretch-stabilized flames to observe soot inception and growth at relatively high flame temperatures common to oxygen enriched applications. Particle size distribution functions (PSDF) measured by mobility sizing show clear trends as the equivalence ratio increases from Φ = 2.2 to Φ = 2.4. For a given equivalence ratio, the measured distribution decreases in median mobility particle size as the maximum flame temperature increases from approximately 1950 K to 2050 K. The median mobility particle size is 20 nm or less for all flame conditions studied. The volume fraction decreases with increasing flame temperature for all equivalence ratio conditions. The Φ = 2.2 condition is close to the soot inception limit and both number density and volume fraction decrease monotonically with increasing flame temperature. The higher equivalence ratio conditions show a peak in number density at 2000 K which may indicate competing soot inception processes are optimized at this temperature. Flame structure computations are carried out using detailed gas-phase combustion chemistry of the Appel, Bockhorn, Frenklach (ABF) model to examine the connection of the observed PSDF to soot precursor chemistry. Agreement between measured and computed flame standoff distances indicates that the ABF model could provide a reasonable prediction of the flame temperature and soot precursor formation for the flames currently studied. To the first order, the trends observed in the measured PSDF could be understood in terms of computed trends for the formation of benzene, naphthalene and other soot precursors. Results of the current study inform particulate matter behavior for methane and natural gas combustion applications at elevated temperature and oxygen enriched conditions.
Heading Toward Trusted ATCO-AI Systems: A Literature Review
Authors: Zhong Jimmy Y.
Published: August 2021

The current review addresses emerging issues that arise from the creation of safe, beneficial, and trusted artificial intelligence–air traffic controller (AI-ATCO) systems for air traffic management (ATM). These issues concern trust between the human user and automated or AI tools of interest, resilience, safety, and transparency. To tackle these issues, we advocate the development of practical AI ATCO teaming frameworks by bringing together concepts and theories from neuroscience and explainable AI (XAI). By pooling together knowledge from both ATCO and AI perspectives, we seek to establish confidence in AI-enabled technologies for ATCOs. In this review, we present an overview of the extant studies that shed light on the research and development of trusted human-AI systems, and discuss the prospects of extending such works to building better trusted ATCO-AI systems. This paper contains three sections elucidating trust-related human performance, AI and explainable AI (XAI), and human-AI teaming [COPYRIGHT CC BY-NC-ND 4.0, J. Y.

Junction temperature of CMOS electronics cooled by a regenerative cryocooler
Authors: Smirnov Dmitry , Ibanez Federico Martin , Ouerdane Henni
Published: August 2021

The optimal operation of cryo-CMOS electronics requires accurate knowledge of the junction temperature, which may be derived from the design parameters of the mechanical cryocooler and cryospace. Research on the subject has been mostly restricted to limited examples of coupled cryocooler-cryocomputer operation with little quantitative analysis. Here, we develop and experimentally validate an analytical relation between the junction temperature and the parameters of the cryogenic system for the steady-state. For validation, a printed circuit board was placed into the cryospace and cooled to 173 K using a regenerative cryocooler based on the reversed Stirling cycle. The junction temperature was measured in five experiments as a function of five different input clock frequencies. The analytical relation for the junction temperature showed good accuracy with the coefficient of variance of ±2%, the mean biased error of –2%, and the determination coefficient of 0.92. The result of this work permits determining accurately the steady-state junction temperature of a cryo-CMOS electronics in a wide range of cryogenic temperatures for different types of cryocoolers.
Common and distinct factors supporting rule-based and information-integration category learning
Authors: Roark Casey L , Chandrasekaran Bharath
Published: August 2021

The ability to organize variable sensory signals into discrete categories is a fundamental process in human cognition thought to underlie many real-world learning problems. Decades of research suggests that two learning systems support category learning and poses that categories with different distributional structures (rule-based, information-integration) optimally rely on different learning systems. However, it remains unclear how the same individual learns these different categories and whether the behaviors that support learning success are common or distinct across different categories. In the current study, we develop a taxonomy of learning behaviors to investigate which behaviors are stable or flexible as the same individual learns rule-based and information-integration categories and which behaviors are common or distinct to learning success for these different types of categories. We found that some learning behaviors are stable in an individual across category learning tasks (learning success, strategy consistency, learning speed), while others are flexibly task-modulated (learning strategy, learning stability). Further, success in rule-based and information-integration category learning was supported by both common factors (faster learning speeds, higher working memory ability) and distinct factors (learning strategies, strategy consistency). Overall, these results demonstrate that even with highly similar categories and identical training tasks, individuals dynamically adjust some behaviors to fit the task and success in learning different kinds of categories is supported by both common and distinct factors. These results illustrate a need to for theoretical perspectives of category learning to include nuances of behavior at the level of an individual learner.
'Liking' as a First Draft of the Affective Future
Authors: Dayan Peter
Published: August 2021

The psychological and neural distinctions between the technical concepts of 'liking' and 'wanting' pose some important problems for motivated choice for goods. Why should it be that we could `want' something that we do not `like', or `like' something that we would not be willing to exert any effort to acquire? Here, we suggest a framework for answering these questions through the medium of reinforcement learning. We consider 'liking' to provide immediate, but preliminary and ultimately cancellable, information about the true, long-run worth of a good. Such preliminary estimates, viewed through the lens of what is known as potential-based shaping, generally facilitate the temporally complex learning problems that animals face.
