Authors: Oliveira Marcus Solon Sá de 
Published: July 2022

O objeto deste estudo está relacionado com a área de gerenciamento de projetos, e justifica-se pela contribuição na ampliação do conhecimento sobre o uso da escuta ativa como fator comportamental facilitador no gerenciamento de projetos. Objetivo geral: Conhecer, mediante uma revisão sistemática, resultados de pesquisas que tratem do uso da escuta ativa como fator comportamental facilitador para o gerenciamento de projetos em engenharia. Objetivos específicos: Discutir se a escuta ativa gera confiança e credibilidade para um gestor de projetos e reduz falhas na comunicação. Avaliar se a escuta ativa é uma habilidade a ser exigida na seleção de gerentes de projetos. Analisar se a escuta ativa ajuda na qualidade do relacionamento interpessoal e no comprometimento da equipe com o gerenciamento de projetos. Identificar o que ocorre com os gestores de projetos quando suas habilidades humanas prevalecem sobre as habilidades técnicas. O método utilizado ocorreu em oito etapas: delimitação da questão a ser pesquisada; escolha das fontes de dados, eleição das palavras-chave; busca e armazenamento dos resultados; seleção de artigos pelo resumo, de acordo com os critérios de inclusão e exclusão; extração dos dados dos artigos selecionados; avaliação dos artigos e síntese e interpretação dos dados. Os resultados revelam que a escuta ativa: melhora o alinhamento do discurso, deixa a equipe entrosada, gera confiança e credibilidade para o gestor de projetos, reduz falhas na comunicação e é uma virtude desejada pelas empresas para um bom gestor; é uma habilidade a ser exigida na seleção de gerentes de projetos; contribui para a qualidade do relacionamento interpessoal e no comprometimento. Entretanto, quando as habilidades humanas sobrepõem as habilidades técnicas os gestores se tornam referencia positiva e obtém maior êxito na gestão de projetos. Para discurssão temos: A ausência de palavras como qualidade de vida, criatividade e empreendedorismo reflete que os aspectos comportamentais são tratados, apenas, como instrumentos para o desempenho do projeto e satisfação do cliente e não como forma de gerar qualidade de vida no trabalho? A falta de autoconhecimento por parte do gestor de projetos pode prejudicar o uso da escuta ativa em sua ação profissional? Concluímos que a escuta ativa é uma virtude desejada pelas empresas na seleção de um bom gestor e essencial para o sucesso do gerenciamento de projetos, gera confiança e credibilidade, reduz falhas na comunicação e ajuda no relacionamento interpessoal.

Introdução: As síndromes hipertensivas gestacionais (SHG) são uma das maiores causas de morbimortalidade materna. Dentre essas síndromes estão: Pré-Eclâmpsia, Eclâmpsia, Hipertensão Crônica e Síndrome HELLP. Devido à alta prevalência de óbitos por estas condições, atualizações sobre os dados clínicos e epidemiológicos são importantes para o adequado manejo destas Síndromes. Objetivo: Avaliar o perfil epidemiológico das pacientes que apresentaram óbito por SHG entre 2010 e 2020, no Brasil e no estado de Sergipe, destacando as características socioeconômicas maternas e local e momento de ocorrência das mortes, a fim de salientar os pontos de entrave no pré-natal, periparto e puerpério. Método: Trata-se de um estudo observacional e descritivo, com informações coletadas no banco de dados TabNet-DataSUS, com análise do perfil de mortes maternas por SHG, no Brasil e em Sergipe, no período de 2010-2020, usando os seguintes códigos da CID-10: O10-Hipertensão pré-existente com complicação grave no parto e puerpério; O11-Distúrbio hipertensivo pré-existente + proteinúria superposta; O14-Hipertensão gestacional sem proteinúria significativa; O15-Eclâmpsia. Os critérios avaliados foram: prevalência, etnia/raça, escolaridade, período e local da morte. Resultados: Foram registrados 3.395 óbitos no Brasil entre 2010-2020, sendo 1,65%(56 óbitos) em Sergipe, e a maioria decorrente da eclâmpsia 50,81%. As mulheres pardas representam a maioria dos óbitos por SHG(53,91%), e também em Sergipe(60,71%). Sobre o nível de escolaridade, 1.244 mortes(36,64%) ocorreram em mulheres com 8-11 anos de estudos e, em Sergipe, a maior prevalência também se apresentou nessa categoria, com 23 mortes(41,07%). Além disso, no Brasil, a mortalidade materna foi maior no puerpério (60,41%), como também em Sergipe, onde 1,90% dos óbitos ocorreram no período puerperal. Conclusão: A prevalência de morte materna por SHG é alta no Brasil e no Estado de Sergipe. O perfil epidemiológico destas pacientes é formado por mulheres de média escolaridade, pardas e nordestinas, sendo o momento de maior prevalência os 45 dias pós-parto, e a maior frequência de óbitos em ambiente hospitalar. Em Sergipe, o perfil se assemelha ao padrão do país.

El objetivo del presente estudio fue evaluar el comportamiento productivo de corderos en engorda, midiendo parámetros como el peso vivo (PV), la ganancia diaria de peso (GDP) y el consumo de alimento (CAL) en corderos alimentados con ensilado de hojas de Agave tequilana Weber cv azul. Para evaluar el PV, la GDP y el CAL se utilizó un diseño factorial con medidas repetidas a través del tiempo. Los datos obtenidos fueron analizados con el paquete estadístico del programa Statistical Analysis System (SAS; 1998), realizando una prueba de comparación de medias por el método de Tukey. Se utilizaron 20 corderos machos para la evaluación in vivo, asignados a cuatro tratamientos (T) con cinco repeticiones cada uno: T1 = 100% de alimento comercial (AC); T2 = 70% AC + 30% EA; T3 = 40% AC + 60% EA y T4 = 100% EA. El tiempo de engorda fue de 50 días, el cual se dividió en cinco periodos de 10 días cada uno. Los resultados mostraron que no existió diferencia (P>0.05) entre los T1, T2 y T3 al analizar las medias generales de los tratamientos para la variable PV, sin embargo, el T4 si mostró diferencias (P<0.05) al tener el menor peso con relación al resto de los tratamientos. En cuanto a la GDP, los T1 y T2 fueron superiores a los T3 y T4 (P<0.05) siendo estor últimos los que presentan las menores ganancias de peso de manera general a lo largo del tiempo de engorda. En conclusión, los datos revelan que, adicionar 2% de urea en el ensilaje de hojas de Agave tequilana, incrementa de manera importante el contenido de PC y mejora la DIVMS, y que al administrar ese ensilado en una proporción de 30% EA + 70% AC se logran GDP similares a las obtenidas con una dieta a base de AC.

Published: July 2022

Abstract
Optical correlation-domain reflectometry (OCDR), which is known as one of the fiber-optic techniques for distributed reflectivity sensing, conventionally included an acousto-optic modulator, a reference path, and erbium-doped fiber amplifiers in its setup. In this work, by removing all of these components simultaneously, we develop a super-simplified configuration of OCDR, which consists of a light source and a photodetector only. We experimentally show that this system can still perform distributed reflectivity sensing with a moderate signal-to-noise ratio, which will boost the portability and cost efficiency of the OCDR technology.

)O3 (x = 0, 0.1, 0.2, 0.5, 1) films were fabricated on Pt/Ti/SiO2/Si substrates using a chemical solution deposition process in this study. The effect of the Zr/Hf ratio on energy-storage performance was evaluated based on the measurement of P–E hysteresis loops. It is shown that the maximum polarization and the recoverable energy density decrease with the increase of the Hf concentration. The energy efficiency of the Hf-contained films is close to each other but higher than the PbZrO3 film. As a result, the Pb(Zr0.9Hf0.1)O3 film achieved in this work exhibited the highest recoverable energy density of 11.3 J cm−3 and a larger energy efficiency of 55% at 800 kV cm−1, exceeding those of either PbZrO3 or PbHfO3 single-component film. This enhancement was related with the size and homogeneity of the crystal grains.

Published: July 2022

Abstract
The rising of thin-film-based plasmonic electro-optic (EO) devices triggers considerable exploitation of ferroelectric oxide thin films with large EO response. In this study, epitaxial (001)-orientated Ni-doped K(Ta0.6Nb0.4)O3 (KTN) films were fabricated on SrRuO3/SrTiO3 substrates via pulsed laser deposition. In comparison with a pure KTN film, a larger withstand electric field was achieved by Ni doping. The EO measurements revealed that the doping of Ni ions induced a decrease in the effective EO coefficient. Instead, the variation of refractive index by the applicable maximum electric field was increased due to the increment of withstand electric field, particularly for the case of 2% Ni dopant.
High-quality ferroelectric Bi0.5K0.5TiO3‒BiFeO3 solid-solution single crystals grown under high-pressure oxygen atmosphere
Authors: Matsuo Hiroki , Noguchi Yuji 
Published: July 2022

Abstract
Ferroelectric (Bi0.5K0.5)TiO3–BiFeO3 solid solutions are promising materials for high-temperature piezoelectric applications because of their high depolarization temperature. In this study, we demonstrate the successful growth of high-quality (Bi0.5K0.5)TiO3–BiFeO3 single crystals near the morphotropic phase boundary by a flux method. Crystal growth at a high oxygen pressure of 0.9 MPa drastically reduces leakage currents, which enables ferroelectric polarization switching and a piezoelectric response associated with a rotation of polar nanosized domains. This study contributes to further detailed analyses of the relationship between crystal structures and ferroelectric properties of the (Bi0.5K0.5)TiO3–BiFeO3 solid-solution system.

Published: July 2022

The aim of the study was to develop a concept of the etiopathogenesis of miscarriages due to the genetic form of thrombophilia.
Materials and methods. In a prospective cohort study, 143 pregnant women were examined, including 109 with pregnancy loss and genetic defects of hemostasis [main (M) group]; the control (K) group consisted of 34 relatively healthy pregnant women with a light history and pregnancy without risk factors for pregnancy loss. Genetic polymorphisms of coagulation factors and fibrinolysis (1691 G→A FVL, 20210 G→A prothrombin, 675 5G/4G PAI-1, 455 G→A fibrinogen β), endothelial dysfunction (677 C→T MTHFR) were studied with the help of allele-specific polymerase chain reaction.
Results. A comprehensive clinical, laboratory, instrumental and statistical analysis has determined the main risk factors for pregnancy loss. Pathological polymorphisms of hemostasis and endothelial dysfunction genes play an important role in the development of miscarriage, namely the following pathological genotypes: 1691 GA factor V Leiden - increases the risk by 5.3 times (95% CI 1.5-18.5), 20210 GA prothrombin - 26.47 times (1.6-445.7), 675 4G / 4G PAI-1 - 7.5 times (1.7-33.79), -455AA fibrinogen β - 9.7 times (1.3-74.16), 677 CT MTHFR - 2.6 times (1.0-6.2), 677TT MTHFR - 21.7 times (1.3-368.6). It has been found that multigenic forms of thrombophilia predominate in most patients with pregnancy loss - 76.1% (p <0.001, OR = 12.31, 95% CI 4.8-31.55).
Conclusions. The obtained data allowed us to form a concept of the etiopathogenesis of recurrent pregnancy loss due to genetic thrombophilia and justify the need for a personalized approach in each case of pregnancy loss.

Seiring dengan meningkatnya produksi Crude Palm Oil (CPO) di Indonesia, maka akan menghasilkan Limbah Cair Pabrik Kelapa Sawit dalam jumlah yang besar pula. Limbah Cair Pabrik Kelapa Sawit (LCPKS) akan menjadi masalah pencemaran lingkungan jika tidak dikelola dengan baik. Hal ini dikarenakan LCPKS memiliki kandungan Biochemical Oxygen Demand (BOD), Total Suspended Solid (TSS), minyak dan lemak yang melebihi ambang batas baku mutu lingkungan. Oleh karena itu, diperlukan suatu upaya untuk mengurangi kadar BOD, TSS, minyak dan lemak yang terkandung dalam LCPKS ini. Penelitian ini dilakukan untuk mengetahui pengaruh variasi waktu air bubbling terhadap penurunan konsentrasi BOD, TSS, dan minyak & lemak dalam LCPKS. Metode yang digunakan pada penelitian ini adalah metode aerasi menggunakan kolom plat berlubang dengan mengalirkan udara ke dalam LCPKS dan tanpa menggunakan bahan tambahan lain. Variabel tetap yang digunakan adalah volume LCPKS sebanyak 7 L dan debit udara yang dimasukkan dalam LCPKS sebesar 5 Liter/menit sedangkan variabel proses yang diamati pada penelitian ini adalah kandungan BOD, TSS, minyak dan lemak dan variabel perlakuannya adalah perubahan waktu operasi per hari selama 6 hari. Penurunan kandungan BOD terbesar terjadi pada hari ke-2 dengan persentase penurunan sebesar 95,5%. Penurunan kandungan TSS terbesar terjadi pada hari ke-4 dengan persentase penurunan sebesar 91,61%, sedangkan penurunan kandungan minyak dan lemak terbanyak terjadi pada hari ke-5, dengan persentase penurunan sebesar 69,14%.

Published: July 2022

The current study assessed school principals' familiarity with media education and its correlation with their use of social networks in school administration from the perspective of teachers. A relational descriptive approach was adopted and two tools were used to collect data. The first was an interview conducted with a sample of 20 teachers, and the second was a questionnaire administered to a random sample of (607) teachers working in Zarqa Private Schools in Jordan. The results revealed that school principals’ familiarity with media education was perceived as moderate, and a strong correlation was found between their familiarity with media education and their use of social networks in school administration. 90% of the interviewees agreed that the school principal’s knowledge of media education had a positive impact on school administration through social networking. Given the results, several recommendations are made that will be of value to researchers and workers in this field.

Sexuality Education aims to reduce teenage pregnancies and other consequences of risky sexual practices such as sexually transmitted infections including human immunodeficiency virus (HIV) among young people. This descriptive-explorative study explored and described how teachers in the senior phase at Soutpansberg West Circuit, South Africa perceived Sexuality Education in their schools. Ten purposively recruited teachers in the research setting were individually interviewed in 2019. The collected data were thematically analysed. The research findings revealed the teachers’ perceived benefits of Sexuality Education, the barriers to Sexuality Education and impact of Sexuality Education on senior level learners in the study setting. Furthermore, it emerged that teachers used different approaches such as lectures, questions and answers, class discussions, and targeted individuals to facilitate Sexuality Education lessons in their schools. This study recommends the provision of support to teachers through training, access to relevant curriculum resources, as well as the monitoring and evaluation of Sexuality Education programmes in the study setting.

Dramaturgia del cuerpo
Authors: Castro Bedoya Jose Octavio 
Published: July 2022

Este artículo se ocupa de pensar el rol que poseen el cuerpo y la dramaturgia en la creación escénica contemporánea, asimismo del lugar donde se instala el actor-creador en un escenario de investigación-creación como el Laboratorio de Dramaturgia Corporal. Su construcción surge de la indagación sobre las posibilidades creativas que puede arrojar la experimentación en ambientes de formación con un enfoque desde la dramaturgia corporal. Además, en la búsqueda de metodologías que contribuyan a la decolonización del teatro de ese textocentrismo y de modelos establecidos que llevan el ejercicio actoral a la simple reproducción. Esto ubica, tanto al cuerpo como a la dramaturgia, en campos expandidos que permiten una relación dialógica en la construcción de nuevas teatralidades, guiando al estudiante-investigador a la experimentación y al encuentro con lo inexplorado, para arribar a maneras de creación y expresión diferentes de las establecidas por la tradición.
Outsourcing Memory to External Tools: A Review of ‘Intention Offloading’
Authors: Gilbert Sam J. , Boldt Annika , Sachdeva Chhavi , Scarampi Chiara , Tsai Pei-Chun 
Published: July 2022

AbstractHow do we remember delayed intentions? Three decades of research into prospective memory have provided insight into the cognitive and neural mechanisms involved in this form of memory. However, we depend on more than just our brains to remember intentions. We also use external props and tools such as calendars and diaries, strategically placed objects, and technologies such as smartphone alerts. This is known as ‘intention offloading’. Despite the progress in our understanding of brain-based prospective memory, we know much less about the role of intention offloading in individuals’ ability to fulfil delayed intentions. Here, we review recent research into intention offloading, with a particular focus on how individuals decide between storing intentions in internal memory versus external reminders. We also review studies investigating how intention offloading changes across the lifespan and how it relates to underlying brain mechanisms. We conclude that intention offloading is highly effective, experimentally tractable, and guided by metacognitive processes. Individuals have systematic biases in their offloading strategies that are stable over time. Evidence also suggests that individual differences and developmental changes in offloading strategies are driven at least in part by metacognitive processes. Therefore, metacognitive interventions could play an important role in promoting individuals’ adaptive use of cognitive tools.
Nonlinear Evolution of the Magnetorotational Instability in Eccentric Disks
Authors: Chan Chi-Ho , Piran Tsvi , Krolik Julian H. 
Published: July 2022

Abstract
The magnetorotational instability (MRI) has been extensively studied in circular magnetized disks, and its ability to drive accretion has been demonstrated in a multitude of scenarios. There are reasons to expect eccentric magnetized disks to also exist, but the behavior of the MRI in these disks remains largely uncharted territory. Here we present the first simulations that follow the nonlinear development of the MRI in eccentric disks. We find that the MRI in eccentric disks resembles circular disks in two ways, in the overall level of saturation and in the dependence of the detailed saturated state on magnetic topology. However, in contrast with circular disks, the Maxwell stress in eccentric disks can be negative in some disk sectors, even though the integrated stress is always positive. The angular momentum flux raises the eccentricity of the inner parts of the disk and diminishes the same of the outer parts. Because material accreting onto a black hole from an eccentric orbit possesses more energy than material tracing the innermost stable circular orbit, the radiative efficiency of eccentric disks may be significantly lower than circular disks. This may resolve the “inverse energy problem” seen in many tidal disruption events.
