Esto no es un pañuelo: todo lo que usted quería saber sobre los pañuelos verdes y no se atrevía a preguntarle a la moda
Authors: Di Loreto Juan Alberto
Published: August 2021

Un accesorio no es un accesorio, puede transformarse en algo esencial y devenir en un poderoso símbolo social. Lo que en la moda aparece como un ornamento, en lo social se constituye como un significante que condensa una lucha. El pañuelo (y el color) verde se han desplazado de la dimensión publicitaria a la dimensión política en Argentina, creando un nuevo significado. El pañuelo ha constituido en la historia un significante ligado a causas y a mujeres.
Correcciones virtuales. Una reflexión sobre el uso de las videoconferencias en el taller de diseño gráfico durante la cursada a distancia en modalidad online
Authors: Alberdi Isabel
Published: August 2021

La recomendación de las voces con trayectoria en el ámbito de la enseñanza a distancia en modalidad online, es que las reuniones sincrónicas temporales que involucran al docente y su grupo de estudiantes tengan objetivos concretos, por ejemplo organizar e iniciar una jornada de clases o tarea; consensuar sobre algún tema que trabajado; o tomar decisiones. Dada la naturaleza de sus condiciones la duración de las mismas debería ser menor a una hora. Frente al evidente exceso de duración de este tipo de encuentros en las clases del taller de diseño gráfico durante el ciclo 2020 propongo cuantificar, especificar cuándo y detallar para qué tipo de actividad fue usada esta dinámica online durante la cursada. Contrastar observaciones al respecto, desde el ámbito de la enseñanza online, desde la enseñanza proyectual con sus particularidades que se reflejan necesariamente en el taller, y desde lo puesto en práctica durante este ciclo condicionado en modalidad por el contexto.
Educación tras las pantallas, puertas virtuales en los procesos de enseñanza aprendizaje del taller de diseño de Información
Authors: Rivadeneira Cofre Andrea
Published: August 2021

La situación de salud pública nos obligó a todos a situarnos tras una pantalla para continuar con las labores, la educación superior no fue la excepción. ¿Cómo enfrentar a esta virtualidad en carreras como Diseño que son de aplicación práctica y cuya metodología se basa en la realización de proyectos de desarrollo en talleres prácticos? La conectividad y el modelo de enseñanza son dos factores determinantes que se ha podido evidenciar en la virtualización de los talleres proyectuales; de acuerdo al diario El Comercio (2020) los equipos de computación hogareños deben ser compartidos por toda la familia, adultos teletrabajando, estudiantes universitarios conectados muchas horas, todos conectados de modo simultáneo, son algunos de los problemas de conectividad que se han tenido que enfrentarse en los procesos de educación. Partamos por el principal factor y sobre el cual tenemos gran incidencia, el modelo educativo; La carrera de Diseño Gráfico plantea en su documento de rediseño (2017) las estrategias y técnicas didácticas donde el estudiante es el responsable de su aprendizaje, él es quién debe buscar, seleccionar, analizar y evaluar la información para la construcción de su conocimiento y para que esto suceda el docente debe planificar las experiencias que quiere desarrollar en el estudiante así como guiar, motivar y ayudar a los estudiantes durante este proceso. La virtualización a la que nos llevó la pandemia hizo que evidenciemos como estamos aplicando estás estrategias y técnicas didácticas establecidas en el micro currículo. Frascara (2018) nos dice que la enseñanza del diseño debe ser organizada, basándose en la resolución de problemas en forma de proyectos, es ahí donde inicio nuestra labor docente para afrontar esta virtualidad en la educación, la planificación exhaustiva de las actividades, espacios, recursos y hasta dificultades de conectividad que tendrán que enfrentar los estudiantes para lograr generar el conocimiento. En este proceso la participación y comunicación activa de los docentes fue vital para este desarrollo, se monitoreo metodologías, actividades, avances y sobre todo dificultades de los estudiantes.

Authors: Paniagua Rojano Francisco Javier , Pastor Marín Francisco Manuel
Published: August 2021

El objeto de estudio de este trabajo es analizar la estrategia de comunicación empleada por los grandes destinos turísticos de carácter urbano en Facebook y Twitter durante la primera etapa de la crisis generada por la pandemia de COVID-19, así como ilustrar los diversos grados de uso de estos medios sociales e identificar posibles casos de buenas prácticas. Como técnica metodológica, se utiliza el análisis de contenido de las cuentas oficiales de los destinos incluidos en el estudio City Tourism Performance Research, que recoge casos de éxito en el turismo urbano. En total, se analizan 1.695 posts y 925 tuits publicados entre los meses de febrero y abril de 2020 en los perfiles oficiales de Facebook y Twitter de los Organismos de Marketing de Destino (OMD) de Amberes, Berlín, Bogotá, Buenos Aires, Copenhague, Ciudad del Cabo, Hangzhou, Linz, Málaga, Marrakech, Pekín, Seúl, Sapporo, Tianjin, Tokio y Turín. Se observa que los destinos estudiados redujeron de forma drástica su presencia en las redes sociales, que fueron utilizadas más como vía de información que como canal de interacción. Se concluye que desde el punto de vista de la comunicación los destinos turísticos no contaron con una verdadera estrategia de gestión de crisis.

Authors: Márquez-Diego José Jesús , De León-García de Alba Carlos , Rojas-Martínez Reyna Isabel , Sánchez-Pale José Ricardo
Published: August 2021

Recientemente, se ha observado un incremento en la presencia de una posible nueva enfermedad en plantas de maíz que genera prolificidad de mazorcas que los agricultores denominan “mano de chango”. Estos síntomas se han observado en áreas tropicales, subtropicales y del altiplano de México. Observaciones iniciales, en los años 1960s, indicaron, sin pruebas, que esta enfermedad era causada por hongos, insectos, o deficiencias nutricionales con incidencia de hasta 100% y pérdidas en producción de grano. Este es el primer trabajo en que se evalúa la incidencia de la enfermedad en 21 híbridos comerciales en el Valle de Toluca, México, un híbrido comercial y una variedad nativa de polinización libre en el Valle del Mezquital, Hidalgo, y seis variedades mejoradas de polinización libre en Montecillo, Texcoco, México. La mayor incidencia y pérdidas en rendimiento de grano por la enfermedad se observó en los genotipos Aspros HC8 y la variedad nativa “Hidalgo”, en el Valle del Mezquital, Hidalgo, en donde la presencia de síntomas de la enfermedad mostró una considerable reducción en rendimiento. Es necesario continuar estudios para investigar su etiología y generar información para selección de resistencia genética a esta posible nueva enfermedad.
Exploring the Impact of Offering an Undergraduate Lactation Elective Course as a Strategy for Normalizing Breastfeeding
Authors: Efrat Merav
Published: August 2021

Background

More breastfeeding interventions targeting female and male undergraduates before they become parents are needed to foster accurate breastfeeding knowledge, positive attitudes toward breastfeeding, and a greater intent to breastfeed. This study aimed to assess the impact of completing a lactation elective course on undergraduates' breastfeeding knowledge, attitudes, and intention.

Methods

Pre- and postcourse surveys were administered to 96 undergraduates from various majors enrolled in a lactation elective.

Results

From pre- to postcourse, this study found significant increases in undergraduates' breastfeeding knowledge, attitudes, and intent.

Conclusions

Because most undergraduates in the United States become parents only after graduation, universities have an opportunity to foster the knowledge and attitudes needed to breastfeed successfully. As breastfeeding knowledge and attitudes in men and women are strong predictors of breastfeeding intent, initiation, and duration, offering undergraduate lactation elective courses is a promising strategy to improve future parents' breastfeeding knowledge, attitudes, and intention, helping to normalize breastfeeding and improve breastfeeding rates.

Published: August 2021

Introduction

The Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) is a 14-item measure designed to assess a mother's confidence in successful breastfeeding of her baby. This study aimed to determine the confirmatory factor analyses (CFA) and responsiveness to change of the Persian version of the BSES-SF.

Methods

This study was performed in two phases: In the first phase, 400 women were recruited, and then in another phase, 110 pregnant women at 35–37 weeks gestation were randomly selected and assigned into two equal groups (n= 55). Educational intervention was implemented, and data were gathered in the third trimester and at 2 weeks postpartum.

Results

The BSES-SF presented a one-dimensional structure with factor loadings of > 0.40 for CFA and Cronbach's alpha coefficient of 0.92. BSES-SF scores in the intervention group (56.76 ± 4.65) were significantly higher than the control group (48.94 ± 4.85).

Conclusion

BSES-SF can be a valid, responsive, and reliable measure of self-efficacy in response to breastfeeding challenges.

Authors: Accioly Inny , Lamosa Rodrigo de Azevedo Cruz
Published: August 2021

The investigation aimed at understanding the socio-emotional competencies in policies for youth education in facing the transformations in the world of work and the social conflicts in Brazil. It is based on the method of historical-dialectical materialism and seeks to understand the multiple determinations of the problem in terms of structure and superstructure. The article presents the debate on the influence of international organizations on educational reforms and the connections to the world of work. It confronts the fundamentals of socio-emotional competencies through the analysis of the history of policy implementation in the United States. It analyzes the competencies in the high school reform, the BNCC, and its implementation in civic-military schools. Finally, it situates socio-emotional competencies in the context of social conflicts in Brazil and the future perspectives. It concludes that the promotion of socio-emotional competencies presents a tendency of repressive/coercive character that should not be ignored, especially in the scenario of deepening the crisis and intensifying social conflicts.

Authors: Bieniaszewska Aleksandra , Gajewska Ewa , Manikowski Wojciech , Steinborn Barbara
Published: August 2021

Introduction Rhythmic gymnastics is a discipline intended only for women with above-average motor skills such as speed, coordination and jumping ability. Advanced training begins in early childhood, and the selection of candidates is motivated by innate predispositions required by coaches, i.e. appropriate physical conditions, adaptation of the body to exercise and sense of rhythm. Selected gymnasts train by learning to perfectly perform routines with devices such as a ball, ribbon, rope, clubs or hoops. Aim The aim of the study is t show distant motor effects of discontinuation of rhythmic gymnastics. Material and methods Two groups of female gymnasts were compared in the study. The first of them consisted of current training, competitive gymnasts, while the other – female athletes who stopped practicing this discipline. The study checked, among others, the occurrence of possible injuries, pain and their location as well as the consequences of discontinuation of training. All of the obtained results were compared between the groups. Results Currently, training gymnasts suffer from less pain than former female gymnasts, however, already at such a young age, they experience first problems both in the spine and lower limbs. In both groups, the most common conditions are hypermobility, spinal overload syndromes and ankle sprains. Conclusions The results of former female gymnasts clearly show that problems with former female gymnasts are a consequence of practicing rhythmic gymnastics, and their intensity increases over time, leading to long-term effects of practicing this discipline. Keywords: rhythmic gymnastics, sports injuries, consequences of competitive sports, early competitive training.

Authors: Pawlak-Andryszczyk Żaneta Emilia , Andryszczyk Marek , Sobieska Magdalena
Published: August 2021

Introduction Eyesight is crucial for each child to achieve the stages of gross and fine motor development. One of the essential processes during movement is the effect of optical flow on the organ of vision and its influence on the performance of the movement. The phenomenon of optical flow is ubiquitous in everyday activities, and it is still not fully understood how it triggers a reaction. Aim The article is a presentation and summary of the research methodology of various research teams studying the influence of the optical flow on motor reactions in infants. Material and methods Review of publications searched using keywords (optical flow, motor reaction, reflexes, newborn, infant) in databases such as PubMed and ScienceDirect. The methods and conditions presented by various authors are summarized in one table. Results and conclusions Optical flow studies and the influence on motor reactions differ significantly in methodology and study groups, making it impossible to compare the results between all found publications. Most cited studies have shown that optical flow can induce or intensify a motor response in infants. Keywords: newborn, optical flow
Unterwegs ins Mittelalter : Zeitreisen in der deutschsprachigen Jugendliteratur des 21. Jahrhunderts
Authors: Böhlau Sarah
Published: August 2021

Die vorliegende Untersuchung beschäftigt sich mit der Darstellung des Mittelalters in sechs deutschsprachigen Jugendromanen der Gegenwartsliteratur, in denen die fremde Epoche innerhalb der Erzählwelt im Rahmen einer Zeitreise erschlossen wird. Die im Phänomen der Zeitreise manifestierte Verräumlichung der Zeit und die in der Jugendliteratur oft erhöhte Bedeutung liminaler Räume greifen ineinander: Der historische Raum wird zum Schwellenraum, der den Jugendlichen Entwicklung und Identitätssuche ermöglicht. Auch Kultur und Gesellschaft sind in der Adoleszenz Konzepte von zentraler Bedeutung, da die Auseinandersetzung mit der Erwachsenenwelt die Entwicklung von Individualität und Geschlechtsbildern nach sich zieht. Die phantastische Metapher einer Reise durch die Zeit, in der sich Zeit und Raum verknüpfen und damit einen neuen Kulturraum zur Entwicklung bieten, eröffnet so eine Vielzahl von erzählerischen Möglichkeiten für die in der Jugendliteratur zentralen Themen von Weiterentwicklung und Selbstfindung.
VIDA NA EXISTÊNCIA: A UNIDADE DOS MODOS DE SER COMPOSICIONAL E CONSTITUCIONAL
Authors: Reis Róbson Ramos dos
Published: August 2021

No presente artigo, examino o problema da unidade de modos de ser no marco do pluralismo ontológico hermenêutico. Tomando como referência o pluralismo ontológico formulado por Heidegger no projeto da ontologia fundamental, analiso a relação de dependência entre o modo de ser da existência e o modo de ser da vida orgânica. A partir da distinção entre composição e constituição, sustento a tese de que, no ser humano, a existência perfaz o modo de ser constitucional, sendo a vida orgânica o modo composicional. O modo de ser da vida é apresentado como fundante do modo de ser da existência. A relação de fundação é analisada como uma dependência existencial genérica e permanente, mas não como uma relação de dependência essencial. Além disso, examino a dependência epistêmica da vida em relação ao modo de ser da existência. Num sentido não trivial, a dependência epistêmica compromete-se com uma posição robusta, segundo a qual o acesso à vida dos organismos é dependente do acesso à vida que compõe a existência humana. Concluo com o esboço de um programa de tematização dos fenômenos disruptivos em que a vida se torna perspícua na existência.
ERIC WEIL: O HEGELIANISMO FRANCÊS E A QUESTÃO DO SENTIDO
Authors: Castelo Branco Judikael , Costeski Evanildo
Published: August 2021

Neste artigo refletimos sobre a filosofia como “ciência do sentido” e sobre a tarefa do filósofo a partir do pensamento de Eric Weil. Para tanto, retomamos a relação de Weil com a filosofia francesa contemporânea e seu papel na introdução de Hegel na França. Depois, acompanhamos o seu juízo sobre tentativas de superação do hegelianismo, ocupando-nos de escritos de Weil sobre o existencialismo e sobre as interpretações de Sartre, Alquié e Étiemble para o pensamento de Marx. Por fim, colocamo-nos diante do problema capital da filosofia weiliana: a violência. O desafio de Weil é pensar o sentido da filosofia depois do discurso hegeliano do Absoluto, de um lado, e da “violência total” de Hitler, de outro. A relevância da questão se justifica pela própria tessitura do nosso atual cenário político e intelectual. Tornar-se mais uma vez urgente insistir sobre o valor do esforço do filósofo na luta contra a violência.

Electromagnetic reducers in electromechanical systems
Authors: Tkachuk Igor , Kovalenko Mykhailo
Published: August 2021

Currently, due to the rising cost of electricity, low-power wind turbines (1-5 kW) are often used to supply consumers with electricity. In this case, wind turbines are used with both horizontal and vertical axes of rotation, the speed of which at an average wind speed V = 5 ÷ 10 m / s and is quite low, and is approximately n = 100 - 300 rpm. A low-speed electric generator for a wind generator with such a speed of rotation with a direct connection of the wind rotor shaft and the electric generator has a large number of poles and reaches a fairly large size. Therefore, magnifying gears (multiplexers) are often used and can increase the speed of the electric generator several times and, thus, reduce the mass of its active part, because the electromagnetic moment is proportional to the volume of the electric machine. However, manual transmissions are a source of additional noise, require frequent maintenance and reduce the durability of the wind turbine. This article will use permanent magnet reducers for wind turbines, which, unlike mechanical reducers, do not create additional noise, do not require lubrication, their durability is higher, operating costs are also significantly reduced, while the magnetic reducer can be integrated with an electric generator. at a wind rotor power P = 4 kW and speed n = 100-300 rpm, high-speed electric generator and magnetic reducer have approximately 2 times less total weight of magnets and 1.7 times less total weight of active materials (magnetic reducer + electric generator) than a low-speed multipole external generator. The aim of the study is to develop and implement an electromagnetic reducer in electromechanical systems. The basis of such systems are high-coercive magnets.

To achieve this goal, the following tasks are set:

- literary-patent search on the research topic;

- selection of a prototype of a magnetic reducer and calculation of its main parameters;

- development of graphical and numerical models to evaluate the effectiveness of the developed prototype;

- optimization of the design of the magnetic reducer;

- development of a system for converting mechanical energy with low potential into electricity;

- prototyping and experimental studies of the system of conversion of mechanical energy with low potential into electrical energy
A definition of the "reactive power" concept
Authors: Honcharov Yevgen , Kruykova Nataliya , Markov Vladyslav , Polyakov Igor
Published: August 2021

A definition of the "reactive power" concept needs to be clarified, since in the literature it is often given extremely vaguely, which causes difficulties in students' perception and is not entirely clear to the general public. Analysis of numerous sources shows that the physical meaning of this concept almost escapes the definitions given in these sources. Moreover, the formula by which the reactive power is calculated raises no objections. However, it does not explain the physical meaning of the concept. The need for a capacious definition that reflects the physical meaning is long overdue. Analysis of literature sources allows us to conclude that reactive power corresponds to the energy that goes from the source to the consumer and returns back, moreover, the process of circulation of this energy proceeds without dissipation. This energy is stored in inductors, keeping the current constant, and in capacitors, because they charge and discharge, keeping the voltage constant. The inductance and capacitance of the circuit consume and return reactive power. The power transferred to the inductor is stored in the magnetic field when the field expands and returns to the source when the field collapses. The power supplied to the capacitor is stored in an electrostatic field when the capacitor is charged and returned to the source when the capacitor is discharged. This power supplied to the circuit by the source is not consumed. It all returns to the source. Thus, the active power, which is the consumed power, is zero. We know that alternating current is constantly changing; thus, cycles of expansion and collapse of magnetic and electrostatic fields constantly occur. The following definition is proposed: non-dissipated electrical energy of alternating current, which excites the magnetic or electric fields, respectively, in inductive and capacitive elements and, coming from them back to the network, is called reactive power.

Authors: De Iure Federico , Amendola Luca , Fabbri Daniele , Chehrassan Mohammadreza , Corghi Alessandro , Cappuccio Michele
Published: August 2021

Case:

We present a 36-year-old man with L1 burst fracture after a sneeze. He was in follow-up for indolent systemic mastocytosis (ISM), and osteoporosis was treated with bisphosphonate. Owing to neurologic impairment, posterior decompressive laminectomy and thoraco-lumbar fusion with cemented screws were performed.

Conclusion:

Vertebral fractures in young patients affected by ISM required a multidisciplinary approach and a careful preoperative planning to achieve acceptable results. These fractures are so rare that even an experienced spine surgeon may not come across them during his whole career. Nevertheless, diagnostic tool improvement makes its diagnosis more frequent, that is why every spine surgeon should know this disease.

Fault damage zones have a higher upscaled permeability than the host rock because of a higher fracture intensity therein. Fracture distribution in the damage zone depends highly on the geometry of fault segments. However, precise images of architectural elements of large-scale faults at depth are difficult to obtain by seismic acquisition and imaging techniques. We present a numerical method that generates fault segments at multiple scales from an imprecise fault trace based on the fractal properties of these segments. The generated fault segments demonstrate hierarchical self-similar architecture, and their lengths follow approximately a lognormal distribution. These characteristics are similar to real fault segments observed in outcrops and seismic surveys. An algorithm that covers fault segments accurately with the minimum number of circles is proposed to calculate the fractal dimensions for both natural and computer-generated faults. The fractal dimensions of natural and generated fault segments are similar and range between 1.2 and 1.4.

In the field of oil and gas exploration, the fluidic down-the-hole (DTH) hammer has frequently been used to solve the challenges associated with hard rock drilling and excessive friction along the drillstring. Appropriate performance prediction for drilling tools is particularly important for the drilling operation. Previous experiments showed that the performance prediction scheme determined by the water was not accurate for fluidic DTH hammer driven by mud, which is a typical pseudoplastic power-law fluid. Based on the results, compared with water, the rheological behavior of the pseudoplastic power-law fluid can be significant for the flow behavior in the fluidic oscillator with a lower supply flow rate. However, for a normal or higher level of supply flow rate, because of the shear diluting effect of the pseudoplastic power-law fluid, the influence of rheology behavior of drilling mud on the performance of fluidic DTH hammer was not apparent. The temperature of the drilling fluid and barite weighting agent can also affect the performance of the fluidic DTH hammer by affecting the rheological properties of the drilling mud. In this paper, numerical simulation and experiments are used for qualitative discussion and conclusion verification, respectively.

Empirical frequency distribution of daily precipitation amounts can be fitted by a negative exponential distribution, because anywhere there are many small daily totals and few large ones. Therefore, the cumulative percentages of days with precipitation, sorted in increasing order according to their amounts, against the cumulative percentage of the rainfall amounts that they contribute are fitted by positive exponential curves Y = aX, a and b constants. Based on these curves, the Concentration Index (CI) evaluates the contribution of the rainiest days to the total amount. In this study the CI has been calculated for 15 meteorological stations in Da Nang city and Quang Nam province in Central Coast Vietnam, for the 1979–2016 period. The results show high values of CI, ranging from 0.62 to 0.72. Conversely, the linear correlation between altitude and CI is negative (R=-0.60, p < 0.01). There are no correlations between the latitude nor the annual mean number of precipitation days and the CI. CI change for the sub-periods of 1979–1997 and 1998–2016 is also analyzed.

The drug resistance has been partly driven by the overuse of antimicrobials in agricultural feeding. Better understanding of the antibiotic resistance in gut of bovine is needed to assess its potential effects based on metagenomic approach and analysis. In this study, we collected 40 fecal samples to explore the drug resistance deriving from antibiotics in bacterial community by an analysis of the diversity and difference of antibiotic resistant genes (ARGs) in gut microbiota from yak, beef and dairy cattle. 1688 genes were annotated, including 734 ARG subtypes in summary. The ARGs were related with tetracycline, quinolone, β-lactam, aminoglycoside, in accordance with the antibiotics widely used in clinic for humans or animals. The emergence, prevalence and differences in resistance genes in the intestines of yaks, beef and dairy cattle may be caused by the selective pressure of different feeding patterns. Additionally, the abundance of ARGs in yak was lower than in beef and dairy cattle, while the abundance of integron, a kind of mobile genetic elements (MGEs), was higher than those in beef and dairy cattle. Furthermore, the results of this study demonstrated that a comprehensive profile of various ARGs among yak, beef and dairy cattle for providing a basic research.
