Cuerpo y movimiento en la educación inicial: concepciones, intenciones y prácticas
Authors: Duarte Sánchez Julieth Alejandra , Rodríguez Laura Carolina , Castro-Martínez Jaime Alberto
Published: December 2019

La presente investigación se basa en teorías del desarrollo y tiene como objetivo revelar cuáles son las concepciones, intenciones y prácticas de maestros y maestras sobre el cuerpo y el movimiento para potencializar el desarrollo integral de niños y niñas en la educación inicial. En este estudio cualitativo participaron cuatro profesoras de dos jardines de Bogotá, Colombia. Los datos fueron recogidos a través de observaciones y entrevistas. Se concluye que existe una carencia en la capacidad de integrar todas las dimensiones del desarrollo, debido a que las maestras se enfocan en componentes individuales, como la motricidad y las funciones cognitivas, por lo que se resta importancia a otros aspectos del desarrollo como las competencias sociales o la relación con el medio.
El hábitat urbano informal y los derechos de la infancia en Bogotá
Authors: Ceballos Ramos Olga Lucía
Published: December 2019

En este artículo se exponen las reflexiones basadas en los resultados de la investigación sobre la relación entre el disfrute de los derechos de la infancia y el hábitat. En esta se abordó lo referido a la vulneración de derechos fundamentales de los niños, niñas y adolescentes (NNA) en Colombia. Se explora el tema en el barrio Potosí, en Bogotá, de origen informal, del cual se presenta lo expresado por niños y niñas, así como de madres, lideresas comunitarias y docentes. La información se contrasta con lo hallado en la literatura sobre la materia de interés, haciendo énfasis en los derechos enunciados en el artículo 44 de la Constitución Política de Colombia de 1991. Este análisis permitió concluir que existe una relación entre las condiciones del hábitat y la vulneración de los derechos fundamentales de NNA cuando dichas condiciones son deficitarias tanto en la escala urbana como en la arquitectónica.

Published: December 2019

Rice husk (RH) is an agricultural waste that contains cellulose. Rice husk fiber (RHF) can be used as a source of fiber in the manufacture of magnetic nanoparticle biocomposite. The purpose of this study is to synthesize and characterize magnetic nanoparticle biocomposite used as an adsorbent and evaluate its performance on the adsorption of  Mn2+ ions and Total Suspended Solid (TSS) in peat water. Rice husk fiber was delignified to eliminate lignin levels. Furthermore, the biocomposite was made through the solvothermal method with and without the addition of hexanediamine. The products produced are two types of adsorbents, namely magnetic nanoparticle biocomposite with an amino group (RHB-MH) and rice husk fiber biocomposite without an amino group (RHB-M). These biocomposites were used to adsorb Mn2+ ions in peat water. Evaluations were carried out at pH 5, 6, 7, and 8 with an optimum adsorption time of 60 minutes. The solutions at the time of adsorption were evaluated to determine the optimum conditions of the adsorption process carried out. The observation of magnetic nanoparticle biocomposite based on the analysis of Scanning Electron Microscopy (SEM) shows magnetic nanoparticles formed on the surface of rice husk fiber with a diameter of 30-50 nm. X-Ray Diffraction (XRD) analysis showed that the delignification of rice husk increased Crystallinity Index (CrI) by 64.98% and reduced silica content by 78%. Fourier Transform Infra-Red (FT-IR) spectrometer show absorption peak at 570 cm-1 for Fe-O bonds and Fe3O4 peak around 1627 cm−1, indicating the presence of N-H bending. The optimum condition for Mn2+ adsorption was achieved at pH 5 and 60-minutes duration with an adsorption capacity of 54.7 mg/g and 190.78 mg/g for RHB-M and RHB-MH. The TSS reduction achieved the effectiveness of 60.2% and 90.3% for BSP-M and BSP-MH, respectively.

Authors: Suhendar Usep , Fathurrahman Muhammad , Sogandi Sogandi
Published: December 2019

One of the problems frequently found in the oral cavity is dental caries caused by Streptococcus mutans. Thus far, dental caries is treated using antibiotics. However, the bacterium is known to be resistant to many antibiotics; hence, another alternative is needed. An alternative option is found in the Kasturi mango (Mangifera casturi). This study aims to identify the bioactive compounds of  Kasturi mango and find out the mechanism of its action in inhibiting the growth of Streptococcus mutans. Kasturi mangoes were macerated using 96% methanol, then the phytochemical compounds were identified qualitatively. Antibacterial activity testing was carried out using the agar diffusion method, and bioactive compounds were identified using GCMS. The results showed that the methanol extract of Kasturi mango contains alkaloids, flavonoids, phenolics, terpenoids, and saponins. In 1 gr/mL of the methanol extract of Kasturi mango fruit has an inhibitory activity against the growth of Streptococcus mutans with a zone of inhibition of ± 10 mm and MIC (minimum inhibitory concentration) value of 25% extract. The inhibitory action is suspected to be through a mechanism where holes in the bacterial cell membrane are made. This can be seen from the results of SEM (scanning electron microscope) images showing that cell leakage or lysis has occurred. This research also, for the first time, revealed the types of bioactive compounds from the methanol extracts of Kasturi mango (Mangifera casturi) consisting of 18 compounds with the most abundance is 5-Hydroxymethylfurfural compounds, Octadecenoic acid, n-Hexadecanoic acid, Phenyl 4-methyl-1-piperidine carboxylate, and Methyl linolenate.

Authors: Yuliyati Yati B. , Solihudin Solihudin , Noviyanti Atiek Rostika
Published: December 2019

Reactive groups such as silanol, hydroxyl, and carbonyl groups in silica-lignin composites play a role in binding to chromium(VI) ions. The activation of functional groups in silica-lignin can be increased by the addition of an activator such as sodium periodate, which can also oxidize the lignin monomer (guaiasil) to ortho-quinone. This study aimed to obtain silica-lignin composites from rice husks activated by sodium periodate with a high surface area. Composite absorption was tested on chromium(VI) adsorption. Silica-lignin isolation was carried out by using the sol-gel method at concentrations of sodium hydroxide 5, 10, 15, and 20% (b/b). Silica-lignin activated with sodium periodate 10% (b/b) had the smallest particle size of about 8μm, with a surface area of 14.0888 m2.g-1 and followed Halsey isotherm adsorption model, with an adsorption capacity of 0.3054 mg.g-1.

Published: December 2019

Activated carbon is one of the most commonly used adsorbents in a variety of separation processes because it is inexpensive, and also the design and principal of application are quite simple. The ability of activated carbon as an adsorbent is related to its large surface area and pore volume, varying pore structure, and diverse surface reactivity. The use of microwave radiation can further improve the efficiency of activated carbon adsorption. Micro-waves can affect the pore texture and surface of the activated carbon, but rarely do both practitioners and researchers control these variables influencing the relationship between features and performance of biomass-based activated carbon as an adsorbent at the time of manufacture from the initial stage (carbonation) to carbon application active (e.g., adsorption of heavy metals, surfactants, and organic molecules). This study aims to synthesize activated carbon from rice husk, which has the efficiency and capacity of adsorption of heavy metals such as Pb and activator organic molecules used is ZnCl2 30% and microwave radiation. This research has succeeded in making activated carbon using the ZnCl2 activator and microwave radiation. The time and power of microwave radiation that provides the highest efficiency in the carbon activation process for Pb ion adsorbate, were 7 minutes and 800 W. For phenol adsorbate was 5 minutes at 800 W. The highest efficiency time and concentration of adsorption for Pb ion adsorbate were 40 minutes at 60 ppm while for phenol adsorbate were 5 hours at 100 ppm. The adsorption efficiency for Pb cation adsorbate was 99.57%. While for phenol adsorbate is 81.05%. Characterization with FTIR, SEM-EDX, and SAA showed a C-Cl bond, the pores were visible, and an increased surface area of activated carbon was 36.9 times the surface area of carbon and the pores formed were mesoporous.

Unification of data from various seismic catalogues to study seismic activity in the Carpathians Mountain arc
Authors: Braclawska Agnieszka , Idziak Adam Filip
Published: December 2019

The Carpathian Mountainsarc is the most seismically active area in Central Europe. Analysis of the seismicity of entire Carpathian arc requires data from each of the particular catalogues which have to be properly and uniformly entered, standardized and merged. For our study we first had to prepare a database of seismic events (ML≥ 1.6) compiled from the data of earthquakes taken from individual national seismic networks as well as data from international seismic centers. However, a careful review of these catalogues has uncovered significant inconsistencies, particularly discrepancies in the description of the location, magnitude and completeness of seismic events. To address these inconsistencies, a newly created compound earthquake catalogue was compiled from the aforementioned seismic catalogues and included events that occurred in the Carpathian Mountains arc area between 1976 and 2017. This work is intended to point out some of the problems associated with collecting data from various seismic catalogues as well as the need for their very careful verification, in order to create a uniform set of seismic data across a large area spanning numerous countries. The results suggest that compiling a uniform and dependable earthquake catalogue is crucial for reliable seismic studies.
A Practical Method for Ablation Catheter Reintroduction into the Left Atrium via Prior Transseptal Puncture, without Radiation
Authors: Pang Lingpin , Chen Song-wen , Zhou Gen-qing , Wei Yong , Chen Can , Huang Shi-an , Liu Shao-wen
Published: December 2019

Background: We evaluated the feasibility and safety of reintroducing an ablation catheter (ABL) into the left atrium (LA) through a previously punctured interatrial septum under guidance of the show-catheter image-track function of the CARTO 3 3-dimensional (3D) electroanatomic mapping system.
Methods: One hundred consecutive paroxysmal or persistent drug-refractory atrial fibrillation (AF) patients (men: 55; mean age, 64.7 ± 12.1 years) who had undergone 2 fluoroscopy-guided transseptal punctures and anatomical LA reconstruction under CARTO 3-guidance, and required ABL reinsertion into the LA during mapping or ablation, were included. They were randomized 1:1 to the show-catheter (reintroduction under the CARTO 3 show-catheter image-track function) or fluoroscopy group (reintroduction under conventional fluoroscopy).
Results: Although the reconstructed 3D anatomy map was displaced in 21/100 patients (21.0%), the ABL was successfully reintroduced in all patients. In the show-catheter and fluoroscopy groups, model displacement incidence (18% versus 24%), tachyarrhythmias (46.0% versus 52.0%), complications (2% versus 4%), and number of ABLs reintroduced into the LA (3.3 ± 0.8 versus 3.1 ± 0.9) were similar (all P > .05). The show-catheter group displayed shorter ABL reintroduction time (9.5 ± 5.5 s versus 156.4 ± 35.5 s, P < .01), ABL reintroduction X-ray exposure time (0 s versus 39.3 ± 13.8 s, P < .01), and total X-ray exposure time (4.1 ± 1.4 min versus 4.7 ± 0.8, P < .05).
Conclusion: During AF ablation, the catheter can be safely reintroduced into the LA, without additional fluoroscopy, under guidance of the CARTO 3 show-catheter image track function.

Published: December 2019

Introducción: La artroplastía cervical es una cirugía que implica el uso de implantes discales con la capacidad de conservar el movimiento del segmento. Constituye un reto para paises como el nuestro desarrollar alternativas a los altos costos de los mencionados implantes, con diseños patentado, elaborado viables de manufacturar, con biocompatibilidad, seguridad, y que simule lo máximo posible los movimientos cervicales fisiológicos. Objetivo: Desarrollar la geometría y mecánica de un diseño discal patentado, elaborado, sea por manufactura aditiva de titanio ELI, así como verificar su compatibilidad con la fisiología de los movimientos cervicales. Métodos: El diseño del estudio tuvo tres etapas iterativas: la primera, el desarrollo de la geometría del implante y el estudio de elementos finitos utilizando como referencia normas internacionales; en segundo lugar, se desarrollaron estudios de metalografía, caracterización del material incluyendo pruebas de fatiga del implante; finalmente, se utilizó un modelo animal cadavérico para confirmar la compatibilidad del implante con los movimientos cervicales. Resultados: Se demostró que el implante elaborado sea por manufactura aditiva o por forja, fue compatible con las normas internacionales. Se realizaron 84 estudios de rayos X en 18 cuellos de porcino. En el 100% de las columnas cervicales de los porcinos, el rango en flexión fue menor que el de extensión. Existió mayor rango de movimiento cuando se utilizaron dos implantes y cuando el implante fue más grande. Conclusiones: El implante cervical flexible elaborado por forja o por manufactura aditiva de titanio ELI presentó resultados prometedores, por lo que podría postularse su uso experimental en pacientes tributarios de artroplastía cervical.

Influence of Yield Strength Variability over Cross-Section to Steel Beam Load-Carrying Capacity
Authors: Kala J. , Kala Z.
Published: December 2019

Authors of article analysed influence of variability of yield strength over cross-section of hot rolled steel member to its load-carrying capacity. In calculation models, the yield strength is usually taken as constant. But yield strength of a steel hot-rolled beam is generally a random quantity. Not only the whole beam but also its parts have slightly different material characteristics. According to the results of more accurate measurements, the statistical characteristics of the material taken from various cross-section points (e.g. from a web and a flange) are, however, more or less different. This variation is described by one dimensional random field. The load-carrying capacity of the beam IPE300 under bending moment at its ends with the lateral buckling influence included is analysed, nondimensional slenderness according to EC3 is λ¯ = 0.6. For this relatively low slender beam the influence of the yield strength on the load-carrying capacity is large. Also the influence of all the other imperfections as accurately as possible, the load-carrying capacity was determined by geometrically and materially nonlinear solution of very accurate FEM model by the ANSYS programme.
Kinetics of Biocatalytical Synergistic Reactions
Authors: Kulys J.
Published: December 2019

Kinetics of biocatalytical synergistic reactions has been analyzed at non-stationary state (NSS) and at quasi steady state (QSS) conditions. The application to the model kinetic constants taken from the first type of the experiments shows that QSS can be established for the enzyme and the mediator at time less than 1 s. Therefore, the analytical solution of the initial rate (IR) may be produced at relevant to an experiment time, and the dependence of the IR on substrates concentration may be analyzed rather easy. The use of kinetic constants from the second type of reactions shows that QSS is formed for the enzyme but not for the mediator. For this reason the modeling of the synergistic process was performed by solving the ordinary differential equations (ODE). For this purpose the novel program KinFitSim (c) was used.
Review on some Stefan Problems for Particle Dissolution in Solid Metallic Alloys
Authors: Vermolen F. J. , Vuik C. , E.  , Van der Zwaag S.
Published: December 2019

This paper is a review of a suite of mathematical models of increasing complexity on particle dissolution in metallic alloys. This work deals with models for multi-component particle dissolution in multi-component alloys, where various chemical species diffuse simultaneously, and a two-dimensional model incorporating interfacial reactions as in the model of Nolfi [1]. The work is mathematically rigorous where asymptotic solutions and solution bounds are derived but is also of a practical nature as particle dissolution kinetics is modelled for industrially relevant conditions.
A Comparative Study of Two Real Root Isolation Methods
Authors: Akritas A. G. , Strzebonski A. W.
Published: December 2019

Recent progress in polynomial elimination has rendered the computation of the real roots of ill-conditioned polynomials of high degree (over 1000) with huge coefficients (several thousand digits) a critical operation in computer algebra.

To rise to the occasion, the only method-candidate that has been considered by various authors for modification and improvement has been the Collins-Akritas bisection method [1], which is a based on a variation of Vincent’s theorem [2].

The most recent example is the paper by Rouillier and Zimmermann [3], where the authors present “... a new algorithm, which is optimal in terms of memory usage and as fast as both Collins and Akritas’ algorithm and Krandick variant ...” [3]

In this paper we compare our own continued fractions method CF [4] (which is directly based on Vincent’s theorem) with the best bisection method REL described in [3]. Experimentation with the data presented in [3] showed that, with respect to time, our continued fractions method CF is by far superior to REL, whereas the two are about equal with respect to space.
Fixed Point in Minimal Spaces

Published: December 2019

This paper deals with fixed point theory and fixed point property in minimal spaces. We will prove that under some conditions f : (X,M) → (X,M) has a fixed point if and only if for each m-open cover {Bα} for X there is at least one x ∈ X such that both x and f(x) belong to a common Bα. Further, it is shown that if (X,M) has the fixed point property, then its minimal retract subset enjoys this property.
Investigation of Accuracy of a Calibrated Estimator of a Ratio by Modelling
Authors: Chadyšas V. , Krapavickaitė D.
Published: December 2019

Estimator of finite population parameter – ratio of totals of two variables – is investigated by modelling in the case of simple random sampling. Traditional estimator of the ratio is compared with the calibrated estimator of the ratio introduced by Plikusas [1]. The Taylor series expansion of the estimators are used for the expressions of approximate biases and approximate variances [2]. Some estimator of bias is introduced in this paper. Using data of artificial population the accuracy of two estimators of the ratio is compared by modelling. Dependence of the estimates of mean square error of the estimators of the ratio on the correlation coefficient of variables which are used in the numerator and denominator, is also shown in the modelling.
Numerical Study of the Combined Free-Forced Convection and Mass Transfer Flow Past a Vertical Porous Plate in a Porous Medium with Heat Generation and Thermal Diffusion
Authors: Alam M. S. , Rahman M. M. , Samad M. A.
Published: December 2019

The problem of combined free-forced convection and mass transfer flow over a vertical porous flat plate, in presence of heat generation and thermaldiffusion, is studied numerically. The non-linear partial differential equations and their boundary conditions, describing the problem under consideration, are transformed into a system of ordinary differential equations by using usual similarity transformations. This system is solved numerically by applying Nachtsheim-Swigert shooting iteration technique together with Runge-Kutta sixth order integration scheme. The effects of suction parameter, heat generation parameter and Soret number are examined on the flow field of a hydrogen-air mixture as a non-chemical reacting fluid pair. The analysis of the obtained results showed that the flow field is significantly influenced by these parameters.
Biosensor Response at Mixed Enzyme Kinetics and External Diffusion Limitation in Case of Substrate Inhibition
Authors: Kulys J.
Published: December 2019

The action of a biosensor containing non Michaelis-Menten enzyme was modeled at mixed enzyme kinetics and external diffusion limitation in the case of substrate inhibition. The calculations show that at the electrode surface multi steady-state concentrations of substrate may be generated if diffusion module is much larger than 1 and the substrate bulk concentration is much bigger than Michaelis-Menten parameter. The multi steady-state concentration generates multi response of the biosensor. The production of the multi steadystate may cause the biosensor response oscillation.
Dos estructuras simbólicas del mito de la Quintrala: la bruja y la femme fatale
Authors: Shagulian Jasmin Belmar
Published: December 2019

Catalina de los Ríos y Lisperguer, best known as Quintrala, is a historical figure of the Chilean Colonial period. Within Chilean culture, she became a myth that developed into a literary character variously portraited as a witch, a murderer, and a parricide. To this day, these remain the portraits that have been reproduced in the literary narrative about the character.

In this work I will analyse the symbolic structures of the witch and the femme fatale, which are essential and reiterative in the construction of the narrative discourse about this literary character. For this purpose, I have chosen the figurative structuralism that views a literary text as a sermo mythicus, that is to say, as a myth in which symbolic structures are a part of the mythical discourse advocated by this theory; this kind of discourse is likewise a fundamental and inherent component of the myth of Quintrala that has not been studied as such.

This work aims to examine these symbolic structures embedded in the myth of La Quintrala by analysing and comparing Gustavo Frías’ latest novels, Tres nombres para Catalina: Catrala (2001) and Tres nombres para Catalina: la doña de Campofrío (2003), the work of Magdalena Petit, La Quintrala (2009), that of Mercedes Valdivieso, Maldita yo entre las mujeres (1991), as well as the historical essay Los Lisperguer y la Quintrala by Benjamín Vicuña Mackenna ([1877] 1944) in order to establish the existence through time of a rewriting and a transfiguration of the symbolic structures in these literary works.
La Guerra civil española como tema en la novela gráfica actual
Authors: Izquierdo José María
Published: December 2019

The Spanish civil war and its postwar period remain two of the most important historical references of present-day Spain. Along with themes of strictly political nature addressing that period of time and with the negative aspects of the transition to democracy, themes of memory and postmemory (Hirsch 1992 / Liikanen 2015) appear. Both are closely related to – although not only to – the silencing of the victims of the mentioned historical periods. By this, I am referring to the ones defeated and to the next of kin of the disappeared.

 

Despite the famous affair of the so-called “gentleman’s agreement”, the “amnesia”, the “forgetfulness” or the “silence” of the democratic transition, a variety of narrative works have emerged in recent history; literary works that in various manners have the Civil War and Franco’s posterior dictatorship as topics or common threads in their narrations[1].

The consolidation of a new literary subgenre of hybrid characteristics combining the mode of narration found in novels and the specificities of the comic strip is a novelty in the context of Spanish literature. Although already canonized in the 1970’s in the United States (Eisner, 1978), the subgenre emerged in Spain during the end of the 1990’s. With the turn of the century, a new vision of the Spanish cartoon arrived: it was no longer fundamentally limited to the sphere of children, of satire, or of short comic strips in newspapers. With an expanded format, it began addressing the adult public.

In the selection of graphic novels that I am presenting, there are various narrative strategies and aesthetics elaborated from accounts from the Civil War, and its prolongation in the Second World War, by authors who were not protagonists in the real-life events themselves and whom I include within the wide concept of postmemory. The prevailing ideas in all the texts are as follows: the necessary recuperation of the memory of the Civil War, the presentation of the present as a result of the past and the importance of knowing the points of view of the defeated in order to update the cultural identities of the territorial sphere of the Spanish state

[1] I have already presented one such work during the «Romanist XV» « Escribir de Oídas: Final literature of the memory of the Spanish Civil War and its postwar period” (2012).
Definição de Experiência Fora do Corpo a partir de Relatos de Experiências Similares
Authors: Medeiros Gabriel Teixeira de , Silveira Fernando de Almeida
Published: December 2019

Resumo Diversas abordagens foram utilizadas para entender as Experiências Fora do Corpo (EFC), contudo, não há consenso sobre sua etiologia, definição e características constitutivas. Este artigo buscou comparar definições de EFC com experiências semelhantes, não consideradas como EFC por seus protagonistas. Treze participantes narraram experiências durante entrevistas semiestruturadas, as quais foram submetidas à análise de conteúdo. Três participantes descreveram experiências que se enquadram a três categorias de EFCs distintas. O não reconhecimento da experiência como EFC esteve relacionado à atribuição de causalidade e crenças paranormais e religiosas. Tais dados sugerem a necessidade de separação entre a definição da experiência e sua atribuição de causalidade, bem como uma abordagem multietiológica e fenomenológica no estudo de EFC.

Abstract The main objective of this study was to examine the relations among psychotherapists’ epistemic orientation (i.e., intuitive, empiricist, and rationalist), personal style and emotion regulation strategies. Participants in the study were 674 psychotherapists of different theoretical approaches, who completed an online questionnaire containing measures of epistemic orientation, personal style, and emotion regulation strategies. Psychotherapists profiled as predominantly intuitive tended towards broader attention and greater emotional closeness as compared to those profiled as predominantly rationalist or empiricist. Furthermore, they also reported using more strategies for increasing the effects of positive emotions than rationalists. Implications for training, practice and therapist well-being are discussed.
Conjugality: A Reading According to Edith Stein´s Notion of Community
Authors: Almeida Eunides , Romagnoli Roberta Carvalho
Published: December 2019

Abstract From the book Contribuciones a la fundamentación filosófica de la psicología y de las ciencias del espíritu,Edith Stein introduces intersubjectivity as a requirement for constituting the “I” and the “We”. Accordingly, her definition of community enables us to understand conjugality in its constitutive aspects, highlighting it as one of the spaces of subjectivity formation, reminding us of themes like: self-formation, creativity, ethics, otherness, openness and individual and collective responsibility. The Stein’s analyses, from the concept of person, also clarify that the formation process, specifically correlated to identifying and repeating intra-family and social models, is governed by the laws of sense and not limited to the psychological sphere, showing the possibility of self-configuration and reconfiguration of “oneself” and of conjugality.

Abstract Morality is a human phenomenon that involves sensitivity and skills developed by the individual throughout their social life. Considering the importance of measuring the moral concerns of adults, this paper sought validity evidence for a Brazilian version of the Moral Foundations Questionnaire. Two studies were conducted, using exploratory and confirmatory factor analysis. In the first study, 341 adults (63% women) responded to the on-line questionnaire translated and adapted to Brazilian Portuguese. The results indicated a two-factor structure, and reduced items. In the second study, 371 adults (61% women) participated. Results confirmed the two-factor structure (binding morality and individualizing morality). We conclude that the QFM has satisfactory psychometric properties for use in research.

Authors: Vale Olívia Costa do , Vasconcelos Laércia Abreu
Published: December 2019

RESUMO Estudos de fenômenos culturais, a partir da Análise do Comportamento, contribuem para o planejamento cultural ao utilizar estratégias como o merchandising social. O objetivo desta pesquisa foi analisar metacontingências, a partir de um tema social com forte impacto - tráfico de pessoas - em uma novela brasileira de grande audiência: Salve Jorge. As cenas relativas ao tema foram descritas em termos de contingências, classificadas em sete metacontingências, as quais foram apresentadas em alta frequência no transcorrer dos capítulos. O impacto da novela foi observado no aumento da frequência de notícias sobre tráfico de pessoas em seis jornais, além de denúncias registradas nos períodos anterior, simultâneo e posterior à exibição de Salve Jorge. As notícias são indicadores do efeito positivo da obra de ficção sobre o reconhecimento e definição de “tráfico de pessoas”, o que contribuei para a frequência de denúncias em órgãos competentes e a implementação das intervenções.

Published: December 2019

Resumo O aço ASTM A572 Grau 50 é utilizado na fabricação de conjuntos soldados para aerogeradores, por este motivo, a realização de alívio de tensões é de grande importância para correção dos impactos causados pelos processos de soldagem, bem como, o conhecimento das propriedades finais obtidas com a realização deste processo. O objetivo desse estudo é comparar as propriedades mecânicas e tensões residuais (método de furo cego) em amostras de aço ASTM A572 Grau 50, soldadas pelo processo de arco submerso, submetidas ao alívio de tensões na condição térmica (PWHT) e na condição como soldado (SST), seguindo os requisitos normativos da AWS D1.1-2015. Os resultados da condição PWHT referente a dureza, limite de escoamento, resistência a tração e tensões residuais são menores e os valores de alongamento e energia absorvida ao impacto são maiores do que a condição SST. Ambas as condições foram aprovadas no ensaio de dobramento lateral. Os resultados obtidos demonstram a importância do processo de alivio de tensões que minimiza os efeitos indesejados dos processos de soldagem aos componentes.

Published: December 2019

Resumo No Tailor Welded Blank (TWB) são soldadas chapas de especificações distintas, antes da conformação. Sua caracterização, na região soldada, por métodos convencionais de tração, pode ser dificultada pelo estreito comprimento da solda. Novas metodologias e alternativas são analisadas. Este trabalho visou caracterizar mecanicamente a região soldada de um painel interno de porta veicular, fabricado por TWBs. Realizou-se a caracterização mecânica indireta da região soldada a partir de ensaio de microdureza - normas ASTM-E140 e ISO 18265-2013 - e equação de conversão direta de dureza em limite de resistência à tração (LRT). Os resultados obtidos foram correlacionados com ensaio de tração dos materiais de base, evidenciando qual a melhor conversão. A norma ISO 18265-2013 foi a que mais se aproximou do ensaio direto, com desvio máximo de 30% e mínimo de 9%, sendo o desvio mais acentuado conforme a resistência mecânica do material aumenta. Nos outros métodos, o desvio máximo pode chegar a 40%, sendo menor (11% a 18%, para equação) quando o material apresenta menor LRT. Apesar do desvio observado, a técnica utilizada mostrou-se útil para predizer os estados de deformações e a extensão da zona fundida (ZF) e da zona termicamente afetada (ZTA) de um TWB.

Published: December 2019

Abstract This paper aims to compare the neuropsychological and educational profiles of Brazilian children with dyscalculia (n = 8), dyslexia (n = 13) and without learning disabilities (n = 12). The neuropsychological profile was composed of: (a) intelligence - assessed by the Wechsler Intelligence Scale for Children (WISC-III); (b) attention - WISC-III Coding and Symbol Search subtests; (c) executive functions - Digit Span (backward order) and WISC-III Arithmetic subtests, Pseudoword Repetition Test for Brazilian Children, Stroop Test and Wisconsin Card Sorting Test; (d) memory - WISC-III Digit Span subtest (forward order) and Rey Complex Figures. The educational profile was composed of reading, writing and mathematics, assessed by the Academic Performance Test and the Arithmetic Test. It was found that the groups with dyscalculia and dyslexia did not differentiate in any of the neuropsychological abilities, only in the reading and writing abilities. Neuropsychological variables that could explain these results were discussed.

Published: December 2019

Abstract The article aims to analyze the conceptions conferred by the health professionals that compose the Expanded Nuclei of Family Health (NASF) on their work assignments. This is a qualitative research, in which was used, for the data collection, eight focus groups, with a total of 43 participants. The data were submitted to content analysis. The results outlined the following categories: integrating NASF work with the Family Health Teams (ESF); developing specialized care; promoting intersectionality; contributing to the promotion of teamwork in Primary Care (AB) and strengthening AB. The study indicates the importance of a better understanding of the functions of the NASF, so that it does not restrict the opportunity to perform specialized care in AB. It is pointed out, the need for adjustments in the work processes of the ESF, in order to enable the shared work in the AB.
Religiosidade/Espiritualidade na Prática Clínica: Círculo Vicioso entre Demanda e Ausência de Treinamento
Authors: Raddatz Juliana Schmidt , Motta Roberta Fin , Alminhana Letícia Oliveira
Published: December 2019

Resumo Diante do crescente número de pesquisas sobre Religiosidade e Espiritualidade (R/E), este artigo objetiva analisar a percepção de profissionais da saúde em relação a esses temas. Foram realizadas entrevistas semiestruturadas, coletadas nos locais de trabalho de seis profissionais liberais, utilizando a Análise de Conteúdo de Bardin, na abordagem qualitativa. Seis categorias emergiram das análises qualitativas: 1. R/E: fusão de conceitos e conexão com o transcendente; 2. Espiritualidade como facilitadora; 3. Demanda aparece informalmente; 4. Falta de treinamento; 5. Na prática é diferente; 6. A temática nos currículos acadêmicos. Os resultados indicaram que os profissionais observam a relevância da temática, embora ela apareça apenas de forma implícita. Como um círculo vicioso, a ausência de treinamento adequado pode levar à falta de inserção do tema na formação acadêmica. Futuros profissionais precisam receber treinamento para saber como acolher a religiosidade e a espiritualidade de pacientes/clientes de forma ética, visando a promoção de saúde.

Published: December 2019

Resumo Este estudo (pesquisa-intervenção) avaliou a eficácia e efetividade de um programa semipresencial de formação continuada de professores em habilidades sociais (HS) e a relação entre as características destes (idade, tempo de formação e atuação, autoavaliação e concepções educacionais), variáveis de processo do programa (desempenho nas tarefas e manejo do ambiente virtual) e resultados obtidos (aquisição de repertório e conhecimento em HS). Participaram 11 professores do Ensino Fundamental (1º-5º ano) que responderam a inventário padronizado e questionários antes, durante e depois do programa. Destacam-se os resultados: (a) melhora no conhecimento e repertório de HS (principalmente assertivas); (b) correlações entre os três conjuntos de variáveis, tanto negativas (p. e., do envolvimento e desempenho no programa com manejo do ambiente virtual, tempo de formação, autoavaliação profissional e repertorio de HS), como positivas (p. e., entre habilidades assertivas e manejo de classe). São discutidas implicações para nivelamento/seleção de cursistas e questões de pesquisa.
