Published: May 2023

Atrial myxoma is a rare cardiac disease but has a broad clinical presentation and complication that involves in heart, lungs, brain, and systemic circulation, among them right atrial myxoma is too rare. Commonly atrial myxomas are often pedunculated and soft in texture, it may be intact or free floated in the upper chambers of heart. The myxoma diameter varies from 10 to 150 mm with a weight of between 15 and 180 grams, which is present by a smooth, villous, soft or friable surface. The embolic events are associated with villous and friable myxomas, while the smooth myxomas are associated with obstructive type and are usually large in size. Proper preoperative evaluation and multidisciplinary teamwork helps to improve the post operative outcome, at the same time it reduces the intraoperative risks and increases the chance of survival of the patient. In this case study we had presented a successful excision of rare case of large free-floating pedunculated right atrial myxoma.

Authors: Bozorgmanesh Mohammad Amin , Sadeghi Mojtaba
Published: May 2023

Although cancer is a recognized disorder worldwide, its treatment is a great challenge; and new and effective treatment methods become one of the fundamental demands. However, one of the new treatment approaches for cancer is hyperthermia, which is considered an assistant to surgery, chemotherapy, and radiotherapy. Despite the proven effectiveness of the method, there are numerous challenges in applying it that require recognizing the effective parameters and optimizing them to achieve better and more effective performance. Considering this, the review paper aims to study the optimization of antennas utilized in the cancerous tissue treatment by hyperthermia. However, four different antennas with different purposes are studied and optimized for this purpose. Furthermore, studies show that recognizing and optimizing the design parameters of hyperthermia antennas is likely to greatly improve the performance of the method.

Published: May 2023

Background Female condoms protect against unplanned pregnancies and sexually transmitted infections (STIs) including HIV; however, their uptake is very low in South Africa. Nurses are frontline healthcare workers and are uniquely positioned to promote their use to their clients. This study assesses nurses' knowledge of, attitudes to, and practices regarding the promotion of female condoms at selected primary healthcare facilities in the King Sabata Dalindyebo sub-district of the Eastern Cape, South Africa.Methods A descriptive cross-sectional study was conducted from April to May 2021 at five community health centres in the King Sabata Dalindyebo sub-district, South Africa. A total of 139 nurses completed a self-administered questionnaire. Data were analysed using simple descriptive statistics.Results The majority of the participants (82.7%) were knowledgeable about the female condom. Some participants did not have a good attitude and willingness to promote female condom use to their clients. Junior nurses (enrolled nursing assistants and newly qualified professional nurses) were less knowledgeable about the female condom than more qualified and older nurses. There was no significant association between level of knowledge and attitude or willingness to promote the use of the female condom.Conclusion This study found good knowledge of the female condom among the nurses; however, the knowledge did not translate into a willingness to promote the device at their health facilities. Capacity building of the junior nurses will fill the knowledge gaps identified. Studies exploring the sociocultural issues around the female condom are needed in the region.
Fertility assessment of male wistar rats orally exposed to chloroform stem extract of Portulaca oleracea Linn. (purslane) – An Experimental Study
Authors: Obinna Victoria Chinenye , Agu Gabriel Ogaba
Published: May 2023

Background
Portulaca oleracea Linn. has a history of extensive use as a medicinal plant and is frequently used by traditional medicine practitioners in Nigeria. Different parts of P. oleracea L. have been studied for their effect on reproductive physiology of animals but there is paucity of information on the stem as it relates to male fertility. This study therefore investigated the sub-chronic effect of oral administration of P.oleracea stem extract on male fertility indices (semen analysis, testosterone concentration and testicular histology) in wistar rats.
Methodology
Twenty animals were randomly divided into 4 groups of 5 rats each. Group A(Control) received 0.5 ml of olive oil(vehicle) while Groups B, C & D received 125, 250 & 500 mg/kg of extract respectively for 21 days by oral gavage. At the end, the animals were anaesthetized and blood samples were collected for testosterone assay, caudal epididymis for semen analysis and testes for histology.
Result
P.oleracea stem extract had no significant (p > 0.05) effect on serum testosterone concentration, testicular histoarchitecture and sperm viability, morphology & motility relative to control. However, there was a significant (p = 0.014) reduction in the sperm cell count of rats exposed to the highest dose (500mg/kg) in relation to control.
Conclusion
Oral administration of P.oleracea stem extract as used in this study may have adverse effect on male fertility; thus further study is recommended to ascertain if prolonged exposure will validate this finding.

Important health and management reasons of early sow removal
Authors: PEJSAK ZYGMUNT , TARASIUK KAZIMIERZ
Published: May 2023

Gilt and sow management practices are key factors for the reproduction and production efficiency of any production system. In Poland, the number of piglets born alive per sow per year and the number born alive per sow per lifetime are relatively low. This may have a number of causes. One of them is an unsuitable parity distribution. According to some data, most females are removed from the herd after the first or second parity. As a consequence, the number of piglets born alive per sow per lifetime is small. In some countries, the number of litters per sow per lifetime varies from 3.3 to 5.6, with a total number of 32 to 73 piglets weaned. The average longevity of a sow in various countries ranges from 467 to 969 days. For Poland, precise data are unfortunately lacking, but unpublished data suggest that the number of litters per statistic sow does not exceed 5, although in particular farms this parameter ranges from 3 to 7. According to data available from different farms, early sow culling takes place mostly after the first or second parity. The causes include errors in gilt’s rearing and introduction into the herd, stall acclimatization, and boar exposure. A gilt’s longevity and performance are also determined by her body weight and age at first breeding, feed intake in the lactation period, as well as body weight gained during gestation and 1st lactation. If properly developed and managed, a gilt with high immunity will perform well as a P1 and will continue to be highly productive throughout her lifetime. Otherwise, she will perform poorly in her first parity, after which her longevity is likely to be short. This paper also reviews health-related causes of early sow culling in Polish farms. The most important ones are infertility, embryonic death, stillbirth, mastitis, and MMA (mastitis, metritis, agalactia), as well as infectious pathogens (viruses), such as IAV-S, PRRSV, PCV2, PPV, ECMV, ADV, CSF, or bacteria: Leptospira spp., Brucella suis, and Erysipelothrix rhusiopathiae.
Lead Carboxylates and Chromatic Parameter Changes in Oil-Based Paintings Exposed to Volatile Organic Compounds
Authors: Silva Izabela , Sanchez Benigno , Canela Maria Cristina
Published: May 2023

Some of the main concerns when attempting to preserve artwork regard environmental factors, such as luminosity, temperature and, recently, even atmospheric pollution. From this perspective, volatile organic compounds (VOC) stand out due to the wide availability of contaminating sources in internal museum environments. Amongst artistic objects susceptible to VOC interference, paintings are more likely to undergo it because their stability is closely related to each component. Thus, it is crucial to comprehend the interaction between VOC and paintings, specifically those with inorganic and adhesive pigments, and evaluate changes in chromatic parameters and the formation of metallic carboxylates. Mock-ups of paintings were prepared with cadmium yellow, chromium oxide, ultramarine blue, linseed oil, and lead white or gypsum primer. Exposure was arranged within an airtight container containing a VOC-saturated atmosphere: formaldehyde, acetic acid, hexanal and 2-butanone oxime. Color alteration occurred for ultramarine blue (greenish coloration) and cadmium yellow (lost luminosity). Infrared analysis showed the formation of lead carboxylates (acetate, formate and hexanoate) in all pigments. Micrographs of ultramarine models, verified via scanning electron microscopy, showed that an otherwise flat and homogenous appearance replaced the granular aspect of the paint; the flat regions being indicative of carboxylate formation.

Published: May 2023

En 2019 se diseñó una red de muestreo basada en puntos fijos de censo para monitorizar poblaciones de pequeñas aves riparias en Gipuzkoa. El objetivo de este programa es obtener estimas robustas sobre la probabilidad de ocupación (presencia; ψ), detectabilidad (p), tasa de colonización (γ) y tasa de extinción (ε) de especies como la lavandera cascadeña Motacilla cinerea Tunstall, 1771y el mirlo acuático Cinclus cinclus L., 1758. Este artículo tiene como objetivo mostrar los primeros resultados del programa (censos de 2019 y 2021), poner en valor su utilidad en la monitorización de las especies objetivo y animar la participación de cara a próximos censos. En un 72% de los puntos que se censaron se detectó mirlo acuático. El modelo con un AIC más bajo fue aquel que consideró un efecto positivo en ψde la existencia de presas o azudes, aunque el modelo nulo se situó a menos de 2 unidades AIC. El modelo nulo estima un valor de ψ(±SE) = 0,65 ± 0,09, p= 0,46 ± 0,04,ε= 0,11 ± 0,11, γ= 0,27 ± 0,17. El parámetro ψno varió significativamente entre 2019 y 2021 (2019: 0,65 ± 0,08; 2021: 0,68 ± 0,08). La lavandera cascadeña se detectó en un 80% de los puntos. El modelo con un AIC más bajo fue el que consideró un efecto negativo en ψde la existencia de presas o azudes, pero hubo dos modelos más con un ajuste igual de bueno a datos: el modelo completo (saturado) y otro modelo con efecto positivo de la presencia de cajas-nido sobre ψ. El primer modelo estimó un valor de ψ significativamente superior cuando no hubo presas/azudes y valores de p= 0,52 ± 0,04, ε= 0,17 ± 0,11, γ= 0,59 ± 0,18. Según este modelo, ψvarió significativamente entre 2019 y 2021 (2019: 0,69 ± 0,09; 2021: 0,76 ± 0,09). El tercer modelo estimó un valor de ψinferior cuando no hubo ninguna caja-nido, si bien debe destacarse que este modelo tuvo problemas a la hora de estimar ψen tramos de presencia de caja-nido.

Comportamiento innovador en hoteles de una ciudad colombiana
Authors: Regalado-Calanche Dubys , Calderón-Hernández Gregorio
Published: May 2023

El presente estudio tuvo como objetivo caracterizar el comportamiento innovador de los hoteles. Se llevó a cabo en 70 empresas hoteleras de la ciudad de Santa Marta, Colombia, mediante encuesta realizada al gerente o a quien este delegara. Para la operacionalización de las variables, se tomaron en cuenta dos fases: la generación e implementación de ideas. Se empleó un muestreo no probabilístico por conveniencia. Para el análisis de la información se utilizaron tres tipos de cálculos: primero, se realizó una descripción básica, utilizando cálculos univariados; segundo, se llevó a cabo un análisis de clúster (multivariado), con el fin de identificar subgrupos afines dentro de las empresas estudiadas; tercero, se efectuó un análisis inferencial mediante diferencia de medias entre los tres clústeres. Como hallazgo, se obtuvieron tres clústeres, atendiendo al desarrollo del comportamiento innovador: alto, medio y bajo. Se evidenció la existencia de un aceptable comportamiento innovador en los hoteles de Santa Marta. El menor desarrollo fue en la implementación, más que en la generación de ideas. De acuerdo con los resultados, se propone que futuras investigaciones se orienten a estudiar factores, mecanismos y estrategias que faciliten el comportamiento innovador, para fortalecer los grupos empresariales con menor desempeño en este campo.

Published: May 2023

Este artículo examina la dinámica innovadora en tecnología y trasformación digital de las cooperativas de Antioquia en la fase presente de globalización. Este análisis estuvo atravesado por la pandemia por Covid-19, es decir que aborda los elementos requeridos en las cooperativas para adaptarse a las exigencias de innovaciones tecnológicas y digitales durante épocas de crisis. La metodología utilizada fue cuantitativa a través de un cuestionario enviado electrónicamente a 801 gerentes de cooperativas durante el año 2020, y se obtuvo respuesta de 72 de ellos. De acuerdo a los hallazgos, se puede establecer que la hipótesis H1: el 0,70 de las cooperativas invierte en tecnología para mejorar el desempeño social, no se confirma; por eso, la hipótesis alterna es la pertinente. En conclusión, las cooperativas toman las decisiones de inversión en tecnología basadas en su funcionamiento interno (fidelización) y no en las necesidades de los clientes. Además, pocas entidades invirtieron en tecnología digital durante la crisis ocasionada por la Covid-19.

Therapeutic Applications of Plant and Nutraceutical-Based Compounds
for the Management of Type 2 Diabetes Mellitus: A Narrative Review
Authors: Dinesh Susha , Sharma Sameer , Chourasiya Rajan
Published: May 2023

Diabetes mellitus is a condition caused by a deficiency in insulin production or sensitivity
that is defined by persistent hyperglycemia as well as disturbances in glucose, lipid, and protein
metabolism. Uncurbed diabetes or incessant hyperglycemic condition can lead to severe complications,
including renal damage, visual impairment, cardiovascular disease, neuropathy, etc., which
promotes diabetes-associated morbidity and mortality rates. The therapeutic management of diabetes
includes conventional medications and nutraceuticals as complementary therapies. Nutraceuticals
are bioactive compounds derived from food sources that have health-promoting properties and
are instrumental in the management and treatment of various maladies. Nutraceuticals
are clinically exploited to tackle DM pathogenesis, and the clinical evidence suggests that
nutraceuticals can modulate biochemical parameters related to diabetes pathogenesis and comorbidities.
Hypoglycemic medicines are designed to mitigate DM in traditional medicinal practice.
This review intends to emphasize and comment on the various therapeutic strategies available to
manage this chronic condition, conventional drugs, and the potential role of nutraceuticals in managing
the complexity of the disease and reducing the risk of complications. In contrast to conventional
antihyperglycemic drugs, nutraceutical supplements offer a higher efficacy and lesser adverse
effects. To substantiate the efficacy and safety of various functional foods in conjunction
with conventional hypoglycemic medicines, additional data from clinical studies are required.
Ribosomal Protein S12 and its Effects on Specialized Metabolism of Streptomyces
Bacteria
Authors: Ostash Bohdan
Published: May 2023

Species within the actinobacterial genus Streptomyces represent one of the most gifted natural chemists in the microbial world. Their specialized metabolites attract the interest of the pharmaceutical industry as a source of novel drugs. A majority of these molecules pose an insur-mountable challenge for economically justified production via chemical synthesis. Therefore, sub-merged fermentation-based isolation of such molecules often remains the only viable way to obtain them. This in turn fuels interest in process development programs aiming to maximize the yield of specialized metabolite per volume unit of fermentation medium. Along with the optimization of the medium and the fermentation mode itself, strain improvement remains an important part of an over-all process development endeavor. An improved strain can be generated via application of tradition-al approaches of selection for random or induced mutants and genomics-enabled genetic engineer-ing methods. Here I focus on a specific class of mutations with the gene rpsL for ribosomal protein S12, which often confer resistance to streptomycin in bacteria and upregulate specialized metabo-lism in Streptomyces. The review will portray the evolution of our understanding of the mechanisms behind rpsL mutations, as well as how technological advances change the way these mutations are introduced into the genomes of interest.
Research on Surplus Force (torque) Control and Compensation of Electro
hydraulic Load Simulator
Authors: Gao Bingwei , Zhang Wei , Zheng Lintao , Xu Bin
Published: May 2023

The electro-hydraulic load simulator can simulate any force (torque) load required by the
loaded object under test conditions, which greatly reduces the equipment development time and
cost. However, the process of force loading inevitably creates a surplus force (torque). The existence
of surplus force (torque) in the system will seriously interfere with the loading accuracy of the system
and even damage the equipment in serious cases. In this paper, based on the research status of
the suppression and compensation of the surplus force (torque) in the electro-hydraulic load simulator,
the effective control strategies and methods to overcome the surplus force (torque) in the system
are summarized. This paper analyzes the generation mechanism of the surplus force (torque), and
summarizes the effective strategies to overcome the surplus force (torque) of the system in structural
compensation and control compensation. Using the control method to compensate for the surplus
force (torque) has the advantages of simple structure, convenient debugging, and strong universality.
It is widely used in the electro-hydraulic load simulator to suppress the surplus force (torque). With
the development of control theory, more and more control strategies and methods are applied to restrain
and compensate for the surplus force (torque) in the electro-hydraulic load simulator, which
not only restrains the surplus force (torque) in the system but also improves the loading accuracy
and anti-interference.

Methods:

This paper analyzes the generation mechanism of the surplus force (torque), and summarizes the effective strategies to overcome the surplus force (torque) of the system in structural compensation and control compensation.

Results:

Using the control method to compensate for the surplus force (torque) has the advantages of simple structure, convenient debugging, and strong universality. It is widely used in the electro-hydraulic load simulator to suppress the surplus force (torque).

Conclusion:

With the development of control theory, more and more control strategies and methods are applied to restrain and compensate for the surplus force (torque) in the electro-hydraulic load simulator, which not only restrains the surplus force (torque) in the system but also improves the loading accuracy and anti-interference.
A Study on Fracture Propagation Law of CO2 Composite Fracturing
in Shale Reservoir
Authors: Song Liyang , Wang Jiwei , Sun Zhiyu , Guo Hu
Published: May 2023

Background:

In recent years, CO2 composite fracturing technology has been widely
used in unconventional reservoirs. Compared to conventional hydraulic fracturing, CO2 fracturing
can create complex fractures, replenish formation energy and reduce oil flow resistance. For shale
oil reservoirs with natural fractures, CO2 composite fracturing can not only give full play to the
advantages of complex fracture networks created by CO2 but also make use of water-based fracturing
fluid to create long fractures with high conductivity.

Methods:

Based on fracture fluid flow, stress interference, natural fracture description, and CO2
phase change equation, a CO2 composite fracture propagation model was established in this paper
to simulate the effects of fracturing fluid type, CO2 proportion, construction scale, natural fracture
development, fracturing fluid injection rate and other factors on the propagation morphology of
CO2 injection fracture network in shale oil reservoirs.

Results:

The results show that the water-based fracturing fluid is beneficial to the formation of
long main fractures, but the overall complexity of the fracture network and the effective stimulated
volume of the fracture network are significantly lower than that of CO2 fracturing. The application
of the appropriate proportion of CO2 composite fracturing fluid can give full play to the comprehensive
advantages of CO2 and water-based fracturing fluid and realize the full stimulation of the
reservoir. CO2 fracturing in shale oil reservoirs with low principal stress difference and high natural
fracture development extent can communicate natural fractures in a large range and form a
complex fracture network. For shale oil reservoirs with natural fractures, a high fracturing fluid
injection rate can significantly improve the complexity of the fracture network.

Conclusion:

The CO2 composite fracturing technology is applied to horizontal wells in X shale
reservoir, and the production after fracturing is significantly higher than that of offset wells, which
can be applied in the same type of reservoir and has broad application prospects.
Bioremediation of Heavy Metal in Paper Mill Effluent
Authors: Gupta Priti
Published: May 2023

The pulp and papermaking industry, being a large consumer of natural
resources, i.e., wood and water, has become one of the largest sources of pollution to
the environment. Wastewater generated during various stages of the pulp and paper-making process continues to be toxic in nature even after secondary treatment. The
effluent water contains not only various toxic chemicals such as volatile organic
compounds but also heavy metals like copper, mercury, iron, zinc aluminium, etc. Even
at very low concentrations, most of the heavy metals are toxic and deadly in nature.
Prolonged exposure to heavy metals causes various diseases in humans and animals
either through skin contact, inhalation, or via consuming food materials.
Treatment of pulp and paper industry wastewater by conventional methods is not
efficient due to its complex nature. These conventional methods, either physical,
biological, chemical or a combination of these methods are also not environmentally
safe and economically viable. Complete degradation of heavy metals is not possible by
the application of a single method. The generation of a huge volume of toxic sludge is
an ongoing and major problem. Therefore bioremediation methods are preferred as
they are highly efficient, cost effective, eco-friendly in nature, there is no secondary
waste created in the environment and metabolize the highly toxic heavy metals into
degradable, less toxic components with the help of microbes.
This chapter focuses on Micro-Bioremediation methods using algae, fungi, yeasts and
bacteria as the most preferred medium to treat wastewater generated by the pulp and
paper industry. These are further also used to reduce toxic organic compounds.

Published: May 2023

The catastrophic effect of petroleum contamination on the environment is a
severe problem of global concern. Bioremediation is probably the easiest and most
cost-effective way to treat the contaminants. Several microorganisms ranging from
bacteria, fungi, yeast, algae, etc., are known for their ability to biodegrade different
hydrocarbons. Hydrocarbon degrading microorganisms are largely known for the
release of biosurfactants and other surface-active biopolymers, which decrease the
surface tension of oil particles into smaller entities for their easy degradation
throughout the respective metabolic cycle. Such biopolymers are encoded by several
genes and operon systems which are discussed briefly in this chapter. Information on
such genes help in better understanding the molecular events involved in the microbial
bioremediation of petroleum hydrocarbon.

Published: May 2023

The Internet has come a long way in the previous three decades. It began as
a content-sharing platform for early websites, portals, and search engines. With the
globalization of Internet users, the importance and diversity of Internet material have
increased; the Internet is increasingly connecting people rather than just connecting
information. Other services, such as voice over Internet Protocol (VoIP) and video
chat, as well as social networks, have enabled the social web. The end-user has
changed as a result of the shift from information consumers to contributors and
producers. This trend has accelerated with the introduction of smartphones and Internet
of Things (IoT) devices. Smartphones have ushered in a new era of communication, in
addition to data. End-users may access information from wherever they need to connect
with their environment for basic everyday activities thanks to a new type of
communication. Cabs may be summoned in large cities by pressing a button on a
mobile device and using an app like Uber. The Internet connects things, dwellings,
cities, and everything else that can be linked, with early information associated with
individuals and later users engaging with other users via the social Web. As a result, a
smart platform with a wide range of smart services emerges. This chapter examines the
growing trend of connecting things and the issues they provide in the context of smart
homes and cities, as well as a summary of key technological capabilities.

Penelitian pengembangan nugget dilakukan dengan 5 perlakuan, yaitu A1 (100% daging ayam), A2 (75%daging ayam, da:25% tepung belalang, tb), A3 (67.5% da:32.5% tb), A4 (50% da:50% tb), dan A5 (100% tb) dalam rancangan acak lengkap dengan 3 ulangan untuk dipelajari sifat fisiko-kimia dan organoleptiknya. Nugget perlakuan A2 memiliki prospek yang baik, terlihat dari respon panelis suka (skor 4) untuk semua sifat organoleptik, dengan kandungan gizi yang setara dengan nugget 100% daging ayam (A1), serta sifat fisik berupa warna dan tekstur yang baik. Peningkatan proporsi tepung belalang meningkatkan kandungan gizi terutama protein dari nugget, namun menurunkan skor kesukaan panelis dan warna internal nugget semakin gelap.
Trazando rutas de los procesos audiovisuales amerindios: enfoques, reflexiones y perspectivas
Authors: Triana Gallego Laura Ximena
Published: May 2023

El objetivo del artículo es indagar sobre las iniciativas audiovisuales de la indigenidad en varios contextos socioculturales, particularmente de América Latina y Colombia. Para cumplir con ello, se hace una revisión de la literatura sobre medios audiovisuales ⁠desde la antropología visual, los estudios culturales y otros enfoques analíticos, así como desde las voces de los realizadores indígenas con experiencias audiovisuales emergentes. Estas contribuciones revelan construcciones identitarias que están en constante transformación, demandando la creación de nuevas representaciones a contrapelo de los estereotipos que hasta entonces se han hecho de la indigenidad.
Desde las experiencias latinoamericanas emergentes se destacan diversos relacionamientos sociales y redes colaborativas que se adhieren a un potencial creativo cada vez menos dependiente de las instituciones. En esa línea se perciben, por lo menos, dos tendencias que trazan esas rutas de los procesos audiovisuales amerindios: por un lado, aquellos que usan los medios audiovisuales como instrumento para maniobrar o gestionar las desigualdades sociales y situaciones políticas adversas; por el otro, los procesos artísticos que deconstruyen las imágenes de las representaciones históricas dominantes de la etnicidad a través de la tecnología audiovisual. Al final, el texto propone una reflexión sobre mirar la amerindianidad como un diálogo entre diferentes percepciones culturales, en el cual las visualidades le devuelven el valor a lo simbólico y a lo comunitario.

Por eso, este trabajo busca identificar los grandes desafíos a los que se enfrenta el SENA frente a la aplicación de la Manufactura Aditiva con Metales o AMM por sus siglas en inglés Additive Manufacturing of Metals en los diferentes sectores de la economía y la puesta en marcha de programas de formación que aporten al desarrollo de la misma, para ello desarrolla un Estudio de Caso, que a través de una evaluación de capacidades identifica desafíos y propone un plan de acción a la institución. El resultado constituye una evidencia sobre los grandes retos que enfrenta el Centro de Manufactura Avanzada CTMA en la AMM, los hallazgos permiten identificar aspectos críticos en la implementación e identificación de tecnologías para empresas estratégicas en el sector de manufactura, además, el CTMA no cuenta con una estructura formal de AMM, planeación estratégica, procedimientos y responsables para canalizar la información y las demandas de la industria.
O impacto do feedback explícito no desenvolvimento da produção oral em espanhol como língua estrangeira na educação a distância
Authors: Aguiar Falcão Carla , Weissheimer Janaina
Published: May 2023

Este estudo investiga o tratamento dado à produção oral (PO) em um curso de Licenciatura em Letras Espanhol a distância e analisa se a realização de tarefas de PO contribui para o desenvolvimento dessa habilidade em relação à pronúncia, acurácia gramatical e fluência de aprendizes de espanhol como língua estrangeira (LE) na educação a distância (EaD), avaliando também o impacto de duas formas de feedback no desenvolvimento da produção oral desses alunos em duas coletas (uma de dois semestres e uma de um). Com esses objetivos, foram analisados o ambiente virtual de aprendizagem dos alunos e o material didático usado, aplicados questionários com os 42 alunos e as duas docentes participantes. Para avaliar o desenvolvimento da PO dos alunos, os dividimos em três grupos: experimental, experimental+ e controle. Os do grupo controle realizaram um pré e um pós-teste e não receberam feedback sobre suas produções. Os grupos experimentais realizaram o pré–teste, 3 tarefas de PO e o pós-teste e receberam feedback, sendo o do grupo experimental+ mais explicativo em relação ao experimental. Os resultados mostram que as práticas de PO são preteridas nas disciplinas e que houve um aumento estatisticamente significativo da medida de pronúncia dos grupos experimentais, ao final de dois semestres, o que não foi constatado com relação ao desenvolvimento das demais variáveis analisadas nas duas coletas. Conclui-se dos resultados que a produção oral dos aprendizes de espanhol da EaD é mais beneficiada pela realização de tarefas e pelo feedback mais sucinto recebido a longo prazo.
Da difícil aquisição do conjuntivo versus indicativo por aprendentes portugueses e francófonos
Authors: Marques Antunes Maria Helena
Published: May 2023

A aquisição de conteúdos gramaticais em língua estrangeira sempre se revelou uma tarefa penosa, promovendo-se, por vezes, a competência comunicativa em detrimento do uso correto da língua. A questão do conjuntivo é representativa da problemática referida, na medida em que a assimilação e a utilização deste modo é sempre um processo moroso e árduo. Sendo o português e o francês duas línguas românicas relativamente próximas, seria expectável que os alunos não manifestassem grandes dificuldades no uso do modo conjuntivo, pois os contextos em que ocorre é similar em ambos os idiomas. Contudo, a análise do discurso dos alunos revela dificuldades na seleção dos modos adequados, mesmo quando, nas suas línguas maternas, o contexto implicaria uma eleição idêntica à da língua estrangeira. Pretendemos, portanto, determinar se a problemática escolha do modo se verifica nos mesmos contextos ou se cada grupo de aprendentes evidencia dificuldades inerentes aos valores que o conjuntivo exibe na sua língua materna, apesar das semelhanças entre o francês e o português.
A paisagem linguística: Uma ferramenta pedagógica no âmbito de uma educação plurilingue e para a cidadania global
Authors: Lourenço Mónica , Melo-Pfeifer Sílvia
Published: May 2023

O presente estudo situa o recurso pedagógico à paisagem linguística num quadro de educação para o plurilinguismo e para a cidadania global. Partindo de uma revisão da literatura acerca do potencial educativo da paisagem linguística na educação em línguas, esta contribuição explicita como esta se pode enquadrar numa “pedagogy of engagement”. De um ponto de vista empírico, recorre-se à análise de conteúdo de módulos de ensino/aprendizagem produzidos no âmbito de um projeto europeu cujo objetivo era a conceção, implementação e avaliação de recursos destinados à didatização da paisagem linguística. Os módulos foram analisados tendo em conta três categorias principais que emergiram dos dados e que implicam uma progressão no trabalho didático com paisagens linguísticas: consciência da diversidade linguística, consciência linguística crítica e ativismo linguístico. Os dados permitem reconhecer que o recurso às paisagens linguísticas pode promover uma educação plurilingue e para a cidadania global quando se consideram os seguintes princípios: i) utilização de metodologias ativas, reflexivas e colaborativas direcionadas para a participação dos alunos; ii) promoção da igualdade na educação, através da desconstrução dos processos sociolinguísticos que estão na base de desigualdades sociais; e iii) desenvolvimento de ações promotoras de um compromisso social de professores e alunos com os seus contextos.
La enseñanza de la pragmática a través de ejercicios de traducción pedagógica
Authors: Díaz Ferrero Ana María , Severino Isa Vitória , Porlán Moreno Rafael
Published: May 2023

El conocimiento de los factores pragmalingüísticos es esencial para el dominio profundo de una lengua. En este artículo presentamos un proyecto de interacción virtual entre estudiantes portugueses de español lengua extranjera (ELE) de las licenciaturas de Marketing, Gestão y Contabilidade, de la Escola Superior de Tecnologia e Gestão de Guarda (Portugal) y estudiantes de portugués, lengua extranjera (PLE), del grado de Traducción e Interpretación de la Universidad de Granada (España). Exponemos en primer lugar la importancia del dominio de los factores pragmalingüísticos en el aprendizaje de una lengua extranjera, especialmente en el marco de la formación de futuros traductores e intérpretes, así como para la formación de profesionales del marketing y de la gestión empresarial. A continuación, definimos el concepto de fallo pragmático, y finalmente presentamos las características de una unidad didáctica de interacción virtual cuyo objetivo es el desarrollo de la competencia pragmática a través de ejercicios de análisis contrastivo y de traducción pedagógica.
Estructuras de infinitivo introducidas por la preposición de. Una visión románica
Authors: Diéguez Ignacio Vázquez
Published: May 2023

Se pretende en este texto revisar el concepto de transitividad y, dentro de él, prestar atención al complemento formado por un infinitivo precedido de preposición. En la tradición románica, el verbo transitivo pide un complemento (llamado directo) para llenar su significado. Ese complemento, usualmente, ha sido presentado por la gramática tradicional como un elemento ligado al verbo sin necesidad de unión. Durante los siglos xix y xx ha cambiado esa percepción y ya algunas lenguas (como el francés, el italiano y el portugués) clasifican los verbos transitivos como directos (sin prep.) e indirectos (con prep.) y otros simplemente como transitivos (español, catalán, gallego, rumano), siendo los transitivos indirectos, intransitivos. Con todo, etapas antiguas de la lengua demuestran que la preposición era común como elemento de unión. Se abordará el caso de la preposición de antecediendo al infinitivo; se sistematizará la cuestión y la importancia de ese eslabón, hoy desaparecido en muchas estructuras y mantenido en otras, dependiendo de las lenguas.
