Published: March 2020

The laser terahertz emission microscopy (LTEM) technique, which breaks through the resolution limitation of terahertz waves from millimeter to micrometer scales, has been widely used in many real application circumstances, such as contactless chip nondestructive testing, biosensing, imaging, and so on. Recently developed spintronic terahertz emitters featuring many unique properties such as high efficiency, easy integration, low cost, large size and so on, may also have great applications in LTEM, which can be called spintronic terahertz emission microscopy (STEM). To achieve high efficiency and good performance in STEM, we propose and corroborate a remnant magnetization method to radiate continuous and stable terahertz pulses in W/CoFeB/Pt magnetic nanofilms without carrying magnets on the transmitters driven by nJ femtosecond laser pulses. We systematically optimize the incidence angle of the pumping laser and find the emission efficiency is enhanced under oblique incidence, and we finally obtain comparable radiation efficiency and broadband spectrum in W/CoFeB/Pt heterostructures compared with that from 1 mm thick ZnTe nonlinear crystals via optical rectification under the same pumping conditions of 100 fs pulse duration from a Ti:sapphire laser oscillator, which was not previously demonstrated under such long pulse duration. We believe our observations not only benefit for a deep insight into the physics of femtosecond spin dynamics, but also help develop novel and cost-effective broadband spintronic terahertz emitters for the applications in STEM.

Authors: Xin Lei , Yang Zhongming , Dou Jiantai , Liu Zhaojun , Gao Zhishan , Zhang Xingyu
Published: March 2020

White-light scanning interferometry is an effective and widely used technology for measuring the microscopic three-dimensional morphology of an object. However, it is easily affected by external disturbances and appears to have a non-uniform sampling problem, which reduces the measurement accuracy. In this study, an effective correction algorithm is presented, in which a Hilbert transform and a correlation analysis of the white light interference envelope curves, as well as the simulated ideal interference signal envelope, are employed for a robust and high precision signal correction. In addition, the proposed method is at least 4 times as accurate as a traditional method and achieves a high repeatability, which is analyzed through a simulation and contrast experiments.

O Brasil é um país que historicamente possui uma baixa produtividade. De Negri & Cavalcanti (2014, 2015), ao realizarem um estudo sobre a produtividade da indústria brasileira, identificaram que possíveis fatores para a baixa produtividade da indústria nacional estão relacionados com as práticas gerenciais. Para melhorar as práticas gerenciais e, consequentemente, melhorar a produtividade, pode-se implementar Estratégias de Manufatura. Com base nisso, este artigo apresenta uma Revisão Sistemática de Literatura (RSL) em revistas brasileiras com o objetivo de identificar as características do processo de Implementação de Estratégias de Manufatura (IEM), relacionado com três categorias: Sistemática (passos), Fatores Críticos de Sucesso (FCS) e Ferramentas / Práticas adotadas. Além disso, pode-se identificar uma tendência de crescimento das publicações em IEM, assim como a definição dos autores que desenvolvem pesquisas na área e também os temas relacionados com a IEM. Por fim, são sugeridas diretrizes para o desenvolvimento de frameworks de IEM.

O Lean Manufacturing é uma estratégia de produção aplicada em empresas de diversos segmentos. Seu principal objetivo é reduzir ao máximo os desperdícios a fim de maximizar o lucro. A transição para o referido estágio, entretanto, não é simples e muitas são as barreiras enfrentadas para se alcançar os objetivos supracitados. Nesta trajetória, as empresas apresentarão diferentes estágios de maturidade e a mensuração desta maturidade torna-se importante. Tomando por base as informações mencionadas, o presente artigo tem por objetivo identificar quais são as principais métricas utilizadas por empresas brasileiras na avaliação da maturidade de sistemas lean. Métricas utilizadas em projetos lean foram listadas a partir da literatura e informações sobre a aplicação das mesmas foram levantadas junto a 43 profissionais que participaram de uma survey. Respondentes outliers foram identificados a partir do Escalonamento Multidimensional (EMD) e, na sequência, as métricas foram ordenadas via um mecanismo utilizado pelo software SPSS para combinação linear de variáveis, empregado na Análise Fatorial Exploratória. Os resultados evidenciaram que as métricas mais aplicadas estão relacionadas à produtividade dos funcionários, número de reclamações dos consumidores, tempo de setup, lead times e índice de estoques. Os resultados decorrentes deste estudo poderão ser utilizados por outros pesquisadores em suas futuras pesquisas.
Caixeiro viajante: aplicação da modelagem matemática na otimização de rotas em uma concessionária de energia elétrica
Authors: Ferreira Ivanilda Agustinho
Published: March 2020

Este artigo apresenta um estudo de caso em uma concessionária de distribuição de energia elétrica brasileira com o objetivo de realizar uma aplicação sobre o Problema do Caixeiro Viajante (PCV). Visando otimizar as rotas das equipes de manutenção de subestações através da disponibilização de coordenadas do Google Maps das respectivas unidades consumidoras (UC) das subestações de um determinado estado. Essa otimização de rotas foi modelada utilizando o Problema do Caixeiro Viajante (PCV), juntamente com o Visual Basic for Applications (VBA) e o UFFLP integrado ao Microsoft Excel 2007. Com o intuito que as equipes de manutenção percorram o caminho de menor distância entre as possíveis subestações a serem visitadas, com a finalidade de executarem suas ordens de serviços. Desde que a equipe de manutenção, saísse primeiramente da sede da concessionária, percorresse as subestações estabelecidas e retornasse no final para a sede, sem existir a possibilidade de passar mais de uma vez na mesma subestação denominada de cliente, correspondendo assim, a melhor rota encontrada quando comparada com a sequência estabelecida inicialmente pela concessionária. Portanto, os gráficos e as figuras permitiram uma interpretação objetiva e notório sobre os dados e resultados dos indicadores de performance. Essa otimização contribui na redução do tempo gasto em deslocamentos, resultando em uma disponibilidade em mão de obra para executarem outras atividades. Influência também no aumento de indicadores de desempenho por equipe, além de diminuir os custos relacionados à manutenção dos veículos.

Authors: Rashid Fraidoon , Hussein Devan O. , Zangana Hawar A.
Published: March 2020

The Tertiary rocks of Khurmala Formation in the Taq Taq oil field have been studied using wireline log analysis, drilling cutting descriptions with integration of mud logging report, and test results for understanding reservoir potentiality and fluid distribution. The formation comprised dolostone and dolomitic limestone with an intercalation of clay layers between the recognized beds. The formation has variable thickness throughout the field, 99.8 m from the northeastern limb and 109 m in the southeastern plunge. The calculated shale volume in the studied interval shows a high rate of the clay contents which in some points the gamma ray has 100% of shale. The corrected log-derived bulk porosity subdivided the Khurmala Formation into 5 porosity units from the top to the bottom including (Kh-1, Kh-2, Kh-3, Kh-4, and Kh-5). The first (Kh-1), third (Kh-3), and fifth (Kh-5) porosity units have the average porosity ≥0.10 (10%) that can be considered as good reservoir unit in terms of porosity, whereas the shale contents reduced the reservoir quality of these units. However, well hydrocarbon entrapment through interconnected fractures and fault in the other Tertiary reservoir was recorded in Taq Taq field , but the weak connectivity of the pores in the Khurmala Formation caused this rock interval remains as water bearing zone.
TECNOLOGIAS QUE INTEGRAM PAIS, ALUNOS E PROFESSOR: O CASO DA PLATAFORMA DIGITAL DE UM COLÉGIO PRIVADO
Authors: Borba Eduardo Zilles , Paula Joseane De
Published: March 2020

This paper explores the use of Information and Communication Technologies (ICT) in an educational institution. Its objective is to understand the relationship between students, parents, and teachers when using the digital platform, as well as to verify how each one of them appropriates the technological tool. Reflection is based on the premise that the accelerated pace of technological innovation requires that people increasingly assimilate their potential not only in the business field but also in the scholar communities. More than presenting concepts and theories on ICT (KERCKHOVE, 1995, MACHADO, 2004; VEEN, VRAKKING, 2009; MORAN, 2015, and others), the article carries out an empirical research exercise in which the authors conduct observations to the digital platform of a private school in the city of Taquara (Brazil), besides applying a questionnaire with three parents, three students and one teacher of a 4th-grade class in the same school. This research aims to understand if the classes are more attractive, interactive, collaborative and, especially if there is a greater engagement of parents, students and the teacher due to the possibility of digital connections between them. In short, the results pointed out that the digital platform encourages practices with active methodologies in and outside the classroom (at home). In the universe researched, it was also identified that interactions with digital media encourage student autonomy, but parents could use it to become more involved in the process of learning with their children.

Background: Child development includes physical, psychological and social aspects. The imbalance stimulation provided by parents could develop temper tantrum of child as a form of emotional explosion. The influence factors of tantrum among children are early weaning, improper toilet training, and the way of parenting in tantrum. This study aims to examine factors influence on temper tantrum among pre-school children.     Method: This is descriptive analytical study with case control design. The number of case sample which selected from mothers who have tantrum pre-school child was 42 mothers and 42 control sample were also selected from mothers who have no tantrum child.  Data were analyzed by univariate, bivariate (Chi-Square) and multivariate using logistic regression to examine the most influenced factors.Results: The study shows that early weaning, toilet training and parenting method were significantly influence on temper tantrum of pre-school children. The most influential variable was the parenting method with OR 9,09 and p-value 0,021.  It means negative parenting method 9 times higher influence on tantrum temper behavior among children compared to positive parenting method.  It is suggested that parenting method should emphasize more in educative and discipline including responsibility aspects.
AN EVENT AT THE DAWN OF MODERN KOREAN POETRY: KIM SOWOL’S “AZALEAS”
Authors: JEONG Myeong Kyo
Published: March 2020

Kim Sowol is one of the Korean poets who opened the horizon of modern poetry in Korea. His poem, “Azaleas”(1925) has been known as a masterpiece which Korean people love most to recite as “To Cassandra” of Pierre de Ronsard in France. Nevertheless, this poem has been taken for the highest expression of the traditional sentiment without being appreciated for the quality of the modern poetry as follows: Koreans have sung for a long time the sorrow from the parting with the lover. In “Azaleas”, any reader can see easily the repeat of the same situation and same feeling.

In this article I analyzed the attitude and the intention of the speaker of this poem and reinterpret the theme of poem. In doing so, I found the clever strategy of the speaker in front of the irreversible situation to press secretly the reflection of the lover about his departure. This strategy is the invention of the modern [wo]man which can appropriate the crisis. So, I defined the modern characteristic of this poem and proved that this poem is not a repeated expression of the traditional feeling of the Koreans, but the de/re-construction of that.
EAST ASIA, THE RESTORATION OF MEMORIES AND NARRATIVE OF RETURN
Authors: Ryu Suyun
Published: March 2020

In the early 2000s, Hwang Seok-young published three full-length novels. They were The Old Garden (2000), The Guest (2001) and Sim-Cheong (2003). The return trilogy attracted much attention in that they were works that informed Hwang Seok-yeong’s return to the Korean literary world. He visited North Korea in 1989 and exiled in Germany until 1993. He was imprisoned shortly after returning home in 1993 and imprisoned until 1998. Conflict and anguish due to his personal history overlap in the three works. It was the thematic focus of ‘return’. ‘Return’ is not simply returning. Above all, it is an encounter with ‘self-absence’ and is the most positive return to think of ‘today’. Furthermore, the final goal is to reconcile with the present. Therefore, the three long-time narratives he published were Hwang Seok-young’s return process as a writer.
WHAT IS AN ORAL HEROIC EPIC POETRY? – OVERCOMING THE LIMIT OF THE ILIAD
Authors: Park Jongseong
Published: March 2020

The ancient Greek epic Iliad, including the oral epic and the written epic, has enjoyed a solid status as a ‘heroic epic’ (or ‘narrative poetry’) of European literature. But if a reader takes look at the general aspects of the heroic epic of oral tradition, it turns out that Iliad is not a typical work of a typical epic, but rather an individual one. Because the birth, trials, performance, and ending of a hero’s life are divided relatively evenly, and the general pattern of transferring the hero’s life to the heroic epic of oral tradition can be found in such cases as Manas, Jangar, Gesar and Mwindo.
Circuit Stability to Perturbations Reveals Hidden Variability in the Balance of Intrinsic and Synaptic Conductances
Authors: Onasch Sebastian , Gjorgjieva Julijana
Published: March 2020

Neurons and circuits each with a distinct balance of intrinsic and synaptic conductances can generate similar behavior but sometimes respond very differently to perturbation. Examining a large family of circuit models with non-identical neurons and synapses underlying rhythmic behavior, we analyzed the circuits' response to modifications in single and multiple intrinsic conductances in the individual neurons. To summarize these changes over the entire range of perturbed parameters, we quantified circuit output by defining a global stability measure. Using this measure, we identified specific subsets of conductances that when perturbed generate similar behavior in diverse individuals of the population. Our unbiased clustering analysis enabled us to quantify circuit stability when simultaneously perturbing multiple conductances as a nonlinear combination of single conductance perturbations. This revealed surprising conductance combinations that can predict the response to specific perturbations, even when the remaining intrinsic and synaptic conductances are unknown. Therefore, our approach can expose hidden variability in the balance of intrinsic and synaptic conductances of the same neurons across different versions of the same circuit solely from the circuit response to perturbations. Developed for a specific family of model circuits, our quantitative approach to characterizing high-dimensional degenerate systems provides a conceptual and analytic framework to guide future theoretical and experimental studies on degeneracy and robustness.

SIGNIFICANCE STATEMENTNeural circuits can generate nearly identical behavior despite neuronal and synaptic parameters varying several-fold between individual instantiations. Yet, when these parameters are perturbed through channel deletions and mutations or environmental disturbances, seemingly identical circuits can respond very differently. What distinguishes inconsequential perturbations that barely alter circuit behavior from disruptive perturbations that drastically disturb circuit output remains unclear. Focusing on a family of rhythmic circuits, we propose a computational approach to reveal hidden variability in the intrinsic and synaptic conductances in seemingly identical circuits based solely on circuit output to different perturbations. We uncover specific conductance combinations that work similarly to maintain stability and predict the effect of changing multiple conductances simultaneously, which often results from neuromodulation or injury.
A Novel Method to Adjust Saphenous Vein Graft Lengths Using 3D Printing Models
Authors: Gocer Hakan , Durukan Ahmet Baris , Tunc Osman , Naseri Erdinc , Ercan Ertugrul
Published: March 2020

Background: The optimal length of saphenous vein grafts can be challenging in surgical coronary revascularization. It is the cornerstone for graft patency. In this study, we tried to demonstrate the value of 3D printing in determining optimal saphenous graft length.
Methods: Sixteen patients who underwent bypass surgery with only vein grafts were examined. Patients' measurements of graft lengths were obtained from postoperative CT images and from both 3D print models manually with plastic tubes and via 3D print digital images of Mimics software during segmentation. Another measurement was done using the Fit Centerline tool in the analysis module of Mimics software after segmentation. These 3 measurements were compared.
Results: There was a statistically significant difference between 3 measurement methods for each graft length (P < .001). Measurements of actual grafts were longer than measurements of 3D printed models manually and segmentation images from software were similar (P > .05).
Conclusion: 3D printing models and their software may be used to determine optimal saphenous graft length and the anastomosis site to decrease operation time. It can be deducted from these results that 3D printing is a promising method for reducing operator dependent variables in adjusting graft size and finding optimal anastomosis sites.

Published: March 2020

Lipomas are the most common type of soft tissue tumors. They mainly are located in subcutaneous tissue in the body, including the heart. The cardiac location of lipomas is rare, mostly asymptomatic, and can cause life-threatening complications by rapid growth. The clinical symptoms, when present, occur in evolution with the growth in size, depending upon the location and degree of invasion in the endocardium.
We present the case of a 63-year-old male patient with a large intrapericardial lipoma with an unusual location, originating from the left atrial roof. The initial symptoms of the patient were shortness of breath, dizziness, and mild dyspnea. Transthoracic echocardiography (TTE) was the first line diagnosis method, followed by computed tomography (CT); both showed a large posterior intrapericardial mass. Resection of a 12/8/5 cm lipomatous tumor mass was performed via median sternotomy, under cardiopulmonary bypass (CPB) on the beating heart. Histopathologic examination revealed the presence of diffuse proliferation of large- and medium-sized mature adipocytes consistent with the diagnosis of pericardial lipoma. The patient was discharged at home on the seventh postoperative day, with a marked improvement of his clinical state and effort tolerance. He did not present evidence of recurrence at his 1-year follow up.

Published: March 2020

En el presente trabajo se analizó el Habeas Corpus como una garantía constitucional para la protección de derechos fundamentales vulnerados por el hacinamiento carcelario a la luz de la Ley Estatutaria 1095 de 2006.  Para ello, se indagó acerca de la evolución histórica del Habeas Corpus, se analizó la normatividad nacional e internacional en concordancia con los pronunciamientos de la Corte Constitucional y se determinó el impacto del hacinamiento carcelario en los derechos fundamentales de los individuos privados de la libertad, mediante la exposición de tendencias de política criminal contemporánea (Política Criminal del Enemigo o Populismo Punitivo y Política Criminal Minimalista o de los Derechos Humanos).  Igualmente, se realizó un análisis del hacinamiento carcelario en Colombia estudiando causas y efectos en la población privada de la libertad, apoyado en estadísticas entregadas por el INPEC.
EL PLURALISMO SOCIAL EN LA JURISPRUDENCIA DE LA CORTE CONSTITUCIONAL COLOMBIANA Y SUS EFECTOS EN MATERIA DE REALIZACIÓN DE LOS DERECHOS
Authors: Guarín Ramírez Edgar , Olarte López Luisa , Garzón Barrera Juan
Published: March 2020

A partir de los desarrollos en torno al concepto de pluralismo social, el alto tribunal de lo constitucional en Colombia ha abierto la puerta al reconocimiento de derechos a sectores de la población que durante mucho tiempo fueron excluidos: indígenas, afrodescendientes, comunidades rom, etc. Empero, dichos desarrollos también han conducido a hacer una defensa de las convicciones personales de cada individuo -erigidas como derechos a través del concepto de libre desarrollo de la personalidad- cuyo ejercicio, en ocasiones, interfiere con derechos de otras personas legítimamente constituidos, lo cual es causa de confrontación social. Los enconados debates en casos como los de la eutanasia, el aborto, las uniones de parejas del mismo sexo, la dosis personal, entre otros, son muestra de ello.    Jurídicamente la problemática se relaciona con temas que refieren al concepto mismo de derecho y los elementos que le estructuran, la recta administración de justicia, el papel de los jueces constitucionales y la conservación del orden social como un bien común.
Logos como distanciación intelectiva en Xavier Zubiri
Authors: Villa Sánchez José Alfonso
Published: March 2020

La investigación sobre la intelección en la obra de Zubiri tiene tres grandes partes: la aprehensión de la realidad, el logos sentiente y la razón sentiente. Este estudio se ubica en la segunda parte, la relativa al logos sentiente. La tesis de Zubiri es que el logos tiene una estructura dinámica, conformada por dos fases. En la primera, llamada fase de impelencia, el logos se distancia de lo meramente real hacia lo que lo real es en realidad. Este movimiento de impelencia es una distanciación intelectiva, cuyos momentos son la retracción intelectiva y la simple aprehensión en sus modos de percepto, ficto y concepto. Este trabajo se interna en esos dos momentos de la impelencia, pero antes de hacerlo da cuenta de unos antecedentes conceptuales que ayuden a entender la naturaleza del logos como distanciación. La segunda fase del movimiento del logos, donde llega a su plenitud, es la afirmación, tema que queda fuera por lo pronto de estas páginas.

Teogonías de los pueblos indígenas en Colombia: ¿una erótica sin dominación?
Authors: Buitrago Rojas Andrea
Published: March 2020

La presente investigación tiene por objeto desarrollar una descripción de las teogonías de los pueblos indígenas inga, misak guambiana, nasa, pasto, yanacona, ette y barí de Colombia, con el fin de ubicar la existencia o ausencia de relaciones de dominación masculina sobre lo femenino en la etnoliteratura indígena. Este trabajo se inscribe dentro de los estudios de narrativa indígena latinoamericana y el enfoque de género, en los que las teogonías se entienden como textos que permiten desarrollar un estudio riguroso sobre la “erótica latinoamericana” (propuesta por Enrique Dussel dentro de la denominada “filosofía de la liberación latinoamericana”) y el contexto político-económico de cada grupo étnico, permitiendo comprender la vigencia, los límites y los escenarios de resistencia en cada grupo étnico en clave de erótica y complementariedad latinoamericana.
Elementos de poder sindical y sus efectos en la desigualdad salarial argentina. Afiliación, negociación colectiva y conflictos laborales
Authors: Gómez Maria Celeste
Published: March 2020

La participación de los sindicatos en la dinámica de las relaciones laborales y la vida institucional de Argentina ha fluctuado de la mano de las distintas orientaciones políticas y económicas de los gobiernos nacionales. La literatura rescata, desde comienzos del siglo XXI, una considerable revitalización en estas organizaciones, junto a cierto crecimiento en el nivel de conflictividad laboral de los trabajadores. Al mismo tiempo, se registraron fuertes caídas en los indicadores de desigualdad salarial, mejoras en el nivel de empleo, creciente inflación y fuertes pujas distributivas. Postulando tres elementos de poder sindical como las negociaciones colectivas, la afiliación y los conflictos laborales, el objetivo de este artículo es examinar el vínculo entre ellos y el nivel y distribución de los salarios de los trabajadores formales del sector privado. Los resultados arrojan evidencia diferenciada según la posición de los mismos en la distribución salarial, con particularidades de acuerdo a la dimensión considerada.

Published: March 2020

Physical activity encompasses a series of overall benefits on cardiovascular health and metabolic disorders. Research has recently focused on the hepatobiliary tract, as an additional target of the health-related outcomes of different types of physical exercise. Here, we focus on the global features of physical activity with respect to exercise modality and intensity, and on studies linking physical activity to lipid metabolism, gallbladder diseases (gallstones, symptoms, complications and health-related quality of life), gallbladder motor-function, enterohepatic circulation of bile acids, and systemic metabolic inflammation. Additional studies need to unravel the pathophysiological mechanisms involved in both beneficial and harmful effects of physical activity in populations with different metabolic conditions.

Published: March 2020

Background and Aim. Helicobacter pylori infection is very common worldwide, and it is associated with an important gastric pathology. Treatment of this infection is difficult and consists of the combination of two or three antibiotics. However, the rate of resistance to treatment is high. Antimicrobial resistance of Helicobacter pylori is based on its cultivation in the laboratory and testing of phenotypic susceptibility, a time-consuming, laborious method. This study aimed to detect the genetic resistance to antibiotics of Helicobacter pylori in the south-eastern region of Romania.

Methods. Ninety patients with positive rapid urease test gastric biopsy samples were tested. Genetic resistance to antibiotics (fluoroquinolone and clarithromycin) was tested by GenoType HelicoDR kit (Hain Lifescience GmbH, Germany).

Results. Clarithromycin resistance mutations were detected in 20% of patients, the commonest mutation in our study beeing A2147G (associated with high level of clarithromycin resistance and lower cure rates). Fluoroquinolones resistance mutations were detected in 30% of patients, and the most common mutations were D91N, D91G, and N87K. There was no correlation with patients gender or age, with the exception of fluoroquinolone resistance, which was detected more frequently in females.  

Conclusions. Clarithromycin and fluoroquinolone resistance of Helicobacter pylori is moderately high in our study. There is a need for monitoring Helicobacter resistance patterns in Romania to provide data that can guide empirical treatment. This is the first published study on the genetic resistance of Helicobacter pylori in Romania.

Objetivo: avaliar o efeito de um ciclo de melhoria da qualidade na implementação de práticas baseadas em evidências no tratamento de mulheres com doenças hipertensivas gestacionais admitidas em Unidade de Terapia Intensiva Materna (UTIM).Métodos: estudo quase-experimental, sem grupo de controle, realizado numa UTIM de um hospital universitário que seguiu as etapas de um ciclo de melhoria da qualidade. Avaliaram-se nove critérios de processo em todas as mulheres admitidas com diagnóstico de doenças hipertensivas gestacionais nos períodos anterior (n = 50) e posterior à intervenção (n = 50) em 2015. Estimou-se a conformidade com intervalo de confiança de 95 %, as não conformidades com gráficos de Pareto e a significância da melhoria com teste do valor Z unilateral (α = 5 %).Resultados: o nível de qualidade inicial foi alto em seis dos nove critérios (amplitude: 94-100 %), as práticas com menor adesão foram a “manutenção de sulfato de magnésio” (54 %), “solicitação de ultrassom fetal” (72 %) e “restrição hídrica intravenosa” (78 %). Houve melhoria absoluta em cinco dos nove critérios (amplitude: 2-16 %), que foi significativa para a solicitação de ultrassom fetal (melhoria absoluta: 16 %; p = 0,023) e para o total de critérios (4 %; p = 0,01).Conclusão: a intervenção de melhoria da qualidade proposta aumentou a adesão às recomendações baseadas em evidência para o tratamento de pacientes com doenças hipertensivas gestacionais admitidas em uma UTIM.
Ideas for integrating meaningful immediate repetition tasks in the English as an additional language classroom: promoting fluency
Authors: Zaccaron Rafael
Published: March 2020

Although repetition is at the core of many different approaches to language learning, either implicitly or not, using this pedagogic practice in the additional language classroom is still negatively perceived by some teachers (Bygate and Samuda, 2005). For contemporary research, on the other hand, the use ofrepetition is not incongruous with communicative additional language teaching approaches that bring the use of tasks to the forefront. The use of immediate repeated tasks can benefit learners because it allows the possibility of repeating slightly altered tasks in a meaningful way. Bearing this in mind, this paper describes three immediate repetition tasks that focus on the speaking skill aiming at developing both fluency and accuracy. All are inherently suited for the additional language classroom and can be easily adapted to better suit specific contexts.
The use of collocations across proficiency levels: a literature review
Authors: Goulart Larissa
Published: March 2020

This literature review focuses on the use of formulaic language by English as a second language students (L2). Research on the field of phraseology has shown that mastery of formulas is central for fluency and linguistic competence (Ellis, 1996). Studies on the use of formulaic language by native speakers (Ellis et al., 2008) have shown that native speakers process these structures as a single word. Considering the use of formulaic language by L2 students, research has shown that this can be problematic to learners as they do not know the correct word association (Men, 2018). This paper presents a literature review on the studies of formulaic language, more specifically of collocations, used by L2 learners. The first part of this paper deals with the different definitions of collocations, while the second part focuses on studies on collocation use by L2 learners.
Questões contemporâneas no cinema e na literatura: o desenho de uma sequência didática para o ensino de inglês como língua adicional
Authors: Welp Anamaria Kurtz de Souza , Didio Álvaro Rutkoski , Finkler Bibiana
Published: March 2020

This article presents the design process of a task sequence produced for an English course of the Languages and Arts Program of the Federal University of Rio Grande do Sul. Having as its theme contemporary issues in cinema and literature, the sequence was developed around movie adaptations from the Cinderella tale. The tasks were designed from authentic texts with the final production proposed being a synopsis of a movie adaptation from a literary work. The produced tasks seek to create opportunities for both meaningful language use and broadening of students’ transit in social practices that happen in the target language.

Background: Regardless of a variety of surgical techniques and hi-tech materials for pelvic prolapse treatment, there is no decrease in the disease recurrences.
Aims: Evaluation of the efficacy of the developed method of surgical correction of IIIV degree colpoptosis anterior combined with IIIII degree C-prolapse with the use of titanium mesh implants in reproductive, pre- and postmenopausal female patients.
Methods: Female patients (group I, n = 25) with colpoptosis anterior and cervical prolapse were examined and operated on according to the developed know-how technique with the use of titanium mesh implants. Evaluation of the efficacy of surgical correction of the disease was performed using questioning, pelvic exam with Valsalva manoeuvre, transvaginal and transperineal ultrasound, pelvis MRI. The findings were compared with the result of surgical treatment of 46 (group II) and 32 (group III) female patients operated on without the use of titanium implants. After surgical treatment according to the three-stage surgical program that provides for multifocal fixation of anatomical formations with the use of titanium implants, the case follow-up was performed in 321 months.
Results: Questioning the patients in group I demonstrated their satisfaction with the surgical treatment results that positively affected the quality of life, mood, and contributed to an increase in sexual activity and community commitment. Check-up showed that the surgical correction of prolapse was completely preserved in the patients of group I during 1821 months. Pelvic exam at rest and with Valsalva manoeuvre, transvaginal and transperineal ultrasound, pelvis MRI did not reveal any significant extrusion of the pelvic organs or titanium implants. No mesh-associated complications were observed during the follow-up. Recurrence of genital prolapse was diagnosed in 12 (26%) patients of group II, mesh-associated complications were detected in 6 (18.8%) women of group III.
Conclusions: The preserving three-stage surgical program, developed by us, contributed to optimize the results of surgical treatment, decrease the rate of the disease recurrence, and reduce the risk of the development of mesh-associated complications.
