Traducción y escritura de la primera edición de Le Monde diplomatique en español (1979-1987): agentes, capitales e influencias
Authors: Hernández Tania Paola
Published: August 2023

Le Monde diplomatique es un mensual francés especializado en política internacional. Actualmente existen 37 ediciones extranjeras y es traducido a 20 lenguas (Le Monde diplomatique, 2015). Con el apoyo del gobierno mexicano, la primera edición en español fue lanzada en la Ciudad de México en 1979 con el nombre de Le Monde diplomatique en español. El contenido de esta edición comprendía tanto traducciones en español de los artículos del mensual francés como artículos originalmente escritos en español. Ambas prácticas, traducción y escritura, estaban bajo la responsabilidad de un grupo de exiliados latinoamericanos en su mayoría provenientes de Argentina y Chile. A partir de entrevistas, contratos y otros documentos, este artículo explora la articulación entre la lógica y funcionamiento particulares del campo periodístico mexicano y la identidad profesional de los individuos involucrados en Le Monde diplomatique en español que fue publicado durante la década de 1980. La discusión descansa principalmente en las distintas declinaciones del concepto de capital: capital simbólico, capital político (Bourdieu, 1986; Benson, 1999) y capital militante (Matonti y Poupeau, 2004).
De la historia a la crítica de traducción a través de la obra Calila e Dimna
Authors: Vargas Garcia Liliane
Published: August 2023

Este artículo parte de un enfoque historiográfico y lingüístico que permite pensar la función de la traducción a partir del Livro de Calila e Dimna (1251), considerada como una escritura fundacional que actúa en la conformación de la lengua castellana como vehículo del saber cultural. Se da énfasis a la característica textual que marca la difusión, el conocimiento y la preservación de esta obra a través y solamente por la traducción. Referenciando el contexto histórico en el que se gesta la traducción del texto “objeto”, se aborda el texto “fenómeno” para analizar la traducción como una operación de lenguaje que pone en circulación y redefine presupuestos resultantes del contacto con el otro para engendrar disposiciones lingüísticas, históricas y culturales como elementos decisivos del poder creador, fundador y difusor de la traducción.
Los orígenes de la literatura medieval francesa: entre traducción y creación
Authors: Botero García Mario Martín
Published: August 2023

Este artículo pone de manifiesto la importancia que desempeña la práctica de la traducción en el surgimiento de la literatura novelesca en el norte de Francia en la segunda mitad del siglo XII. Se hace énfasis en la forma en que los clérigos medievales se basan en sus conocimientos en latín, la lengua de la cultura, para dar los primeros pasos en la escritura de textos literarios en lengua vernácula. Así, a partir de la necesidad de dar a conocer textos pertenecientes a la Antigüedad latina a un público laico que desconoce el latín, va a surgir la práctica de la traducción, en cuya base se sitúa el nacimiento de lo que hoy llamamos "novela". El Lai de Narcisse permitirá un acercamiento al método de traducción a mediados del siglo XII.
Traducir la filosofía más allá de la filosofía: firmas, acontecimientos, contextos
Authors: Castro Ramírez Nayelli
Published: August 2023

En estas líneas, muestro algunas de las particularidades de la traducción de “Signature événement contexte” al español. El análisis propuesto  se aleja de los enfoques hermenéuticos (la interpretación y construcción del sentido de un texto) y se acerca a la propuesta de una poética de la traducción. En una primera parte, a manera de introducción, sitúo el estudio de los textos filosóficos en el horizonte de la traductología. En la segunda, analizo la traducción al español de la conferencia. En las conclusiones, señalo las dificultades de clasificación de los textos filosóficos, en particular, los de Jacques Derrida y muestro la necesidad de traducir filosofía más allá del sentido conceptual de sus textos. Traducir filosofía es diferirla, construirla, hacer filosofía.

Reflexiones de Julio Cortázar y Octavio Paz con respecto a traducción desde su punto de vista como escritores
Authors: Navas Forero Ángela Liliana
Published: August 2023

Para construir una teoría latinoamericana de la traducción, es necesario conocer los aportes de quienes, a partir de su experiencia como traductores, han planteado sus propias ideas sobre la traducción. En nuestro continente, la traductología se ha movido de la mano de la literatura, lo cual pone de manifiesto la importancia de analizar las ideas de quienes han trabajado en ambos campos. Son muchas las características que tienen en común el argentino Julio Cortázar y el mejicano Octavio Paz; pero, ¿cuáles son sus ideas en cuanto a la traducción?, ¿en qué están de acuerdo?, o ¿en qué no? La intención de este artículo es esbozar y analizar algunos de los planteamientos de estos dos autores, con miras a entender su valor dentro de la teoría latinoamericana de la traducción.
Estado nutricional infantil y estilos educativos familiares: apreciación de expertos
Authors: Alzate Yepes Teresita , Cánovas Leonhardt Paz
Published: August 2023

Antecedentes: la obesidad infantil ha sido estudiada de manera amplia en aspectos de diagnóstico y tratamiento fundamentalmente, pero aquellos referidos a la prevención desde factores familiares, no genéticos, han estado muy ausentes del foco de las investigaciones en salud y nutrición pública. Objetivo: explorar las apreciaciones de los profesionales de la nutrición sobre las posibles relaciones entre el tipo de familia, el estado nutricional infantil y los estilos educativos familiares. Materiales y métodos: estudio, descriptivo y exploratorio. Se aplicó una encuesta on-line, semiestructurada a profesionales de España, Chile, Portugal y Colombia. Se incluyeron tres variables específicas: tipo de familia, estilo educativo familiar y estado nutricional presunto por el indicador peso para la talla. Resultados: independientemente del tipo de familia, el estilo educativo de lospadres se asoció con el estado nutricional de los niños de la siguiente manera: el estilo protector con exceso de peso, el democrático con estado nutricional normal, mientras los estilos autoritario y negligente se asociaron con malnutrición por exceso o déficit (p<0,05). Conclusiones: este estudio puede ser útil para profundizar, a partir de nuevas investigaciones, en las relaciones encontradas respecto a la obesidad infantil y sus interacciones con su entorno primario.
Validez de la bioimpedancia para estimar la composición corporal de mujeres entre los 18 y 40 años
Authors: Aristizábal Rivera Juan Carlos , Restrepo Calle María Teresa
Published: August 2023

Antecedentes: la aplicación de la bioimpedancia para estimar la composición corporal se ha incrementado recientemente en Colombia. Objetivo: evaluar la validez de la bioimpedancia para estimar el porcentaje de grasa corporal (%GC) en mujeres de Medellín-Colombia. Materiales y métodos: estudio transversal con una muestra de 52 mujeres entre los 18 y 40 años. El %GC se estimó por hidrodensitometría, bioimpedancia mano-pie con las ecuaciones de Sun y Kotler, y bioimpedancia pie-pie con báscula Tanita. Resultados: los %GC obtenidos por Kotler (31,9±6,0) y Tanita (25,6±6,1) fueron diferentes (p<0,001) del obtenido por hidrodensitometría (29,6±5,3), asimismo, estas técnicas presentaron un bajo grado de acuerdo con este método de referencia, Kotler (Bland-Altman: -2,3 IC95%: -10,9; 6,1) y Tanita (Bland-Altman: 4.0 IC95%: -6,3; 14,3). La ecuación de Sun estimó valores similares a la hidrodensitometría (29,6±5,3 vs. 28,6±5,2, p=0,098) pero presentó un bajo grado de acuerdo con este método (Bland-Altman: 0,9 IC95%: -7,1; 9,0). Conclusiones: la bioimpedancia mano-pie con la ecuación de Kotler y pie-pie con báscula Tanita, no fueron válidas para estimar el %GC de las mujeres evaluadas. La bioimpedancia mano-pie con la ecuación de Sun estimó de forma adecuada el %GC grupal, pero presentó poca validez para estimar el %GC individual en esta población.
Conocimientos, gustos y prácticas sobre el consumo de lácteos en una población escolar de la ciudad de Medellín-Colombia
Authors: Rodríguez E Holmes , Restrepo B Luis Fernando , Martínez H. Libia Inés
Published: August 2023

Antecedentes: el consumo de lácteos es importante para la salud y el desarrollo de los niños, sin embargo en países en desarrollo no se alcanza la recomendación de la OMS de 180 L/persona/año. Objetivos: determinar los conocimientos, gustos y prácticas de consumo de productos lácteos comparativamente con el de gaseosas, en población escolar de la ciudad de Medellín. Materiales y métodos: estudio descriptivo exploratorio de tipo transversal, en el que participaron 384 niños, entre 7 y 12 años, de nueve instituciones educativas. Se efectuó el análisis de los datos aplicando la técnica multivariada MANOVA con contraste canónico ortogonal, empleando el paquete estadístico SAS versión 9.0. Resultados: se encontró un consumo de lácteos de 135,5 L/persona/año, sin diferencia estadística entre sexos (p=0,53) ni entre niveles socioeconómicos (p=0,17). Frente a los conocimientos sobre el consumo de lácteos, solo 38,2% de los niños conoce la cantidad diaria recomendada y 42% el aporte nutricional. Para el 60,4% de los niños, la principal motivación al consumo de lácteos es el sabor. Se encontró un consumo de gaseosas y refrescos de 132,7 L/persona/año. Conclusiones: es necesario mejorar los conocimientos de los niños sobre la importancia del consumo de lácteos para la salud, utilizando campañas educativas para fomentar su consumo.
Entrenamiento de la memoria con neurofeedback en bandas Theta para adultos sanos: una revisión sistemática de la literatura
Authors: Velásquez-Pérez José Luis , Rizo-Arévalo Alejandra
Published: August 2023

El NFB es una técnica que se utiliza ampliamente para estimular procesos cognitivos, como la memoria en población clínica e infantil principalmente, pero son pocas las investigaciones que presenten protocolos experimentales de entrenamiento en memoria en banda Theta en población adulta sana. El objetivo es analizar las características metodológicas de los estudios que apuntan al entrenamiento de la memoria con técnicas de NFB por medio de la onda Theta en adultos sanos. Se hizo seguimiento de pautas para revisiones sistemáticas PRISMA y Manual Cochrane de revisiones sistemáticas de intervenciones. Se obtuvo Coeficiente kappa de Cohen de 0.8, nivel de acuerdo casi perfecto entre jurados quienes de 512 artículos se filtraron por títulos 68, por resumen, 20 y por criterios de inclusión quedaron 7 artículos para analizar. Se encontraron diferencias metodológicas significativas entre los estudios, pero el desempeño de la memoria de trabajo, motora y episódica mejoró en especial cuando se utilizó NFB en banda Theta.
Re-reading Luke's community
Authors: Marevesa Tobias , Mavengano-Marevesa Esther
Published: August 2023

This article interrogates and examines the community of Luke and the ambivalence of the location, composition, and identity problematics issues through the Social Identity Complexity perspective (SIC hereafter). The fundamental questions which this article seeks to grapple with are: Was the community of Luke Corinth, Ephesus, or Antioch? Which social boundary markers were erected among the multiple and complex social groups within the community of Luke? The arguments in this article are framed by insights from the Social Identity Complexity Theory which was developed by Roccas and Brewer (2002). The SIC perspective is useful and relevant in re-reading and problematizing identity markers of the numerous social groups within the community of Luke. The article also explores a significant aspect of the troubled composition of the social groups in the community of Luke. This study established that there are multiple and complex social identity formations in Luke's community. Furthermore, the social identities of the members of the Lukan community were fluid, nuanced, and troubled, as highlighted in the discussion in this article.
other side of whiteness
Authors: Van der Riet Louis , Van Wyngaard George Jacobus
Published: August 2023

This article will provide an overview and analysis of developments in the Dutch Reformed Churchâ€™s (DRC) General Synod concerning race, racism, and racial reconciliation from 1986 until 2019. It seeks to extend the multiple accounts of the DRCâ€™s adoption and rejection of apartheid theology by tracing its further attempts at grappling with questions of racism during and after the transition to democracy, into the present. Three primary discourses are explored, namely the search for an inclusive ecclesiology, the commitment to community involvement in the reconstruction of South Africa after apartheid, and the transformation of interpersonal ethics towards greater respect and care for others. Thereafter, the article highlights four territories that remain largely unexplored within the DRC in the past quarter of a century and argues for their future exploration. These trajectories could contribute to a deeper transformation and conversion from the white Christianity historically tied to the DRC.
Möbius strip of memory and history, faith, and fascism
Authors: Houston Peter
Published: August 2023

Giovanni Palermo was an Italian prisoner of war captured at the battle of Bardia on 3 January 1941 in Libya. He was transferred by ship to Durban and from there, taken to Zonderwater prisoner of war (POW) camp near Pretoria. Palermo published his memoir in 1972 detailing his capture and POW experiences. A close reading of his translated memoir presents several historical challenges. He uncritically makes his personal bias plain from the start, yet at the same time sees himself as the custodian of the true narrative of Italian POW history, even where the historical record indicates a contrary truth to his. Religious and political ideologies present themselves like a Möbius strip at various points throughout his memoir, not least with an opening endorsement by a Christian religious figure who frames what is to follow. Palermo's strongly held views on purity, his self-belief that he is the bearer of the real truth, and his desire to make Italy great again have contemporary societal and theological resonances.
Can human extinction be morally desirable?
Authors: Van Niekerk Anton
Published: August 2023

According to David Benatar’s anti-natalism, the extinction of all sentient life, including that of humans, is morally desirable. That claim is contested in this article. The author commences by showing parallels between Benatar’s position and that of the existentialist Albert Camus. He points out that, also for Camus, the claim that "death is better" is meant in a moral sense. This is followed by a general exposition of Benatar’s anti-natalism. Particular attention is paid to Benatar’s argument about the â€œasymmetry of pleasure and painâ€: the presence of pain is bad, whereas the presence of pleasure is good. However, whereas the absence of pain is good, it cannot necessarily be argued that the absence of pleasure is bad; what can, at most be claimed, is that the absence of pleasure is not bad. The author develops three arguments against Benatar’s position. He firstly (drawing on Dawkins) points out that Benatar’s position contests the most primordial of all instincts that characterize the phenomenon of life, i.e. reproduction. Secondly, drawing on Irenaeus and Hick, the author argues that the idea of a painless sentient existence is untenable. Thirdly, as suggested by the article’s title, the author argues that it does not make sense to promote a moral argument for the desirability of the non-existence of human life, since such an argument presupposes, for its very validity, due recognition as a moral argument or claim in an environment of morally responsible human interactions – that which Benatar’s argument suggests should disappear completely in the universe that he proposes.
Utilization of Christian doctrine as a theological resource
Authors: Kpalam Ebenezer Tetteh , Yates Hannelie , Kotze Manitza
Published: August 2023

The doctrine of the Trinity is a doctrine that should have real and practical implications for daily Christian living. Proponents of the relational view of the Trinity believe that the relationship that exists between the triune God is a relationship of love, equality, and reciprocity. Consequently, this should reflect in the quality of relationship and caring activities created and extended by faith communities. Child Sexual Abuse (CSA) is considered a crime in most societies. It has a devastating long-term effect on the child, family, and society. As a result, all stakeholders are called upon to respond to this menace in society. There is evidence that any effective Christian response should be informed by critical theological reflections. As such, theological reflections sparked by public issues of importance should be rooted in the Christian faith traditions. This article posits that the relational view of the Trinity could be a useful theological resource for pastoral response to CSA.
Queer Monumentality
Authors: Myer Ella
Published: August 2023

This article engages with Dirk J. Smitâ€™s 1986 article â€œThe Symbol of Reconciliation and Ideological Conflict in South Africa.â€ The author illustrates and modifies Smitâ€™s analysis of symbols and their connection to ideology by way of a case study. The case study explores how LGBTQ Americans have sought to access symbolic power contained within their history. The author especially focuses on the forms that LGBTQ Americans have used to construct historical symbols. These forms are the tactical/ephemeral and the monumental. The author closes with a discussion of whether reconciliation symbolics play a role in representations of LGBTQ history in American society and specifically at Princeton Theological Seminary.
Scots Afrikaners
Authors: Fourie Ruhan
Published: August 2023

There seems to be a persistent interest in history of the Scottish influence and legacy in southern Africa’s ecclesiastic scene by both academics and the public. It became particularly evident in 2022 when, in the spirit of the bicentennial commemoration of the arrival of the most notable Scottish import, Andrew Murray, the Stellenbosch Theological Journal devoted a special edition to the legacy of the pivotal Murray-clan. It reflected both the richness of existing literature on Scottish influences and legacies in southern Africa, as well as ongoing debates and perceptive thereon. Retief Müller’s The Scots Afrikaners (2021) proves to be a central text in this historiography. The book covers the Scottish influence, and effects thereof, on the Afrikaner people and the Dutch Reformed Church (DRC). It covers the period from Lord Charles Somerset’s attempt to anglicise the church in the mid-nineteenth century to the mid-twentieth century when the Scottish influence waned under the more dominant volkskerk tradition of emergent Afrikaner nationalism. The development of the Scots Afrikaners – a term Müller uses to describe the hybrid identity of Scottish clergy still tethered to the empire, but who identified with the Afrikaner community – and their dominance of ecclesiastical matters in this period is covered extensively.
Emerging apologetics Themes in contemporary African youth ministry: A Kenyan perspective
Authors: Muriithi Ndereba Dr. Kevin
Published: August 2023

Contemporary Christian ministry and theological education in Africa cannot neglect her children and young people. Engaging effectively with the children and youth in Africaâ€™s cities presents a rising challenge to scholars and practitioners. In addition to the developmental issues surrounding children and youth, there are worldview issues at play among young people. Urban African cities like Nairobi contain a mixture of African traditional religious worldviews, modern worldviews, and postmodern worldviews. This means that Christian ministry with the emerging generations will often take an apologetic mode. The scholarly literature on apologetics in the continent is scanty. Further, much of the research is merely theoretical and lacks empirical insight from practical ministry. This article will use an empirical methodology among African church leaders to collect salient themes in the discipline and practice of apologetics and draw conclusions for ministry and theological education.
Identity, power, and responsibility
Authors: Wessels Wessel
Published: August 2023

Within South African homiletic thought, prophetic preaching has predominately been understood as preaching steeped in Black Theology of Liberation (BTL). Historically homiletics in South Africa showcased both a rejection of BTL as a merely political ideology and promoted BTL as paramount for prophetic preaching in the democratic context. The former relented, whilst the latter is still dominant. However, there has been no research on the implications of prophetic preaching regarding the proposed outcomes of such preaching, which has a relatively broad scope, including poverty relief, development, admonishment of corruption, and the Lordship of Christ in the public sphere. In this article, I will reflect on prophetic preaching as preaching BTL from a postcolonial, psychological, and ethical perspective, locating four potential consequences of prophetic preaching: a colonial identity paradigm, resentment, misrepresentation of the vital flaws of society, and the relenting of personal responsibility.
In "conversation" with Andrew Murray Jr on Johannine Spirituality
Authors: Mouton Elna
Published: August 2023

For Andrew Murray Jr (1828–1917), John 15 was significant for understanding believers’ unification in Christ. Imagining a conversation with him, the essay explores experiences of Jesus’ presence and absence in the Fourth Gospel [FG]. References to God’s presence are characterised by the transferral of “temple” imagery to both Jesus and the Johannine community as the dwelling place where God’s “tabernacling” presence is experienced (1:14; 2:13–22; 14:1–6). These images, distinctive of the ‘household’ dynamic of the FG (1:12–13, 18), are reflected in Jesus’ engagement with his disciples (Jn 13–17) as mutual indwelling between God and them. Amidst hisdeparting words (13:33; 14:2) and his followers’ disillusion and grief (13:36–38; 14:1, 27; 16:20–22), Jesus invites them to “remain/dwell” in him/his love (15:4, 9), waiting upon the Counsellor whom ‘the Father’ will send in his name (14:26; 16:7, 13).
Nurturing a missional spirituality
Authors: Van der Merwe Willie
Published: August 2023

The Dutch Reformed Church of South Africa [DRC] is currently in a season of reorientation, or perhaps one can say, rediscovering its mission. The aim of this article is twofold: firstly, to reflect on the journey of the DRC over the past two decades to discern its role and function in a â€œnewâ€ South Africa as well as the challenges deriving from this journey. Secondly, this article wants to contribute to the commemoration of the arrival of Andrew Murray Sr (1794â€“1866) in South Africa in 1822. The influence of this family on the life and spirituality of the DRC and its mission over the past two centuries is extensive and probably beyond description. When this article therefore dares to explore possible links between the current missional movement in the DRC and the spirituality of Andrew Murray Jr (1828â€“1917), it is done humbly and hesitantly. The article will be presented in four sections. The first section briefly describes the discernment process followed by the DRC since 1998. In the second section the major transformational challenges awaiting the DRC in the next decades will be highlighted, and the third section briefly explores what the transformation may entail. Then the article goes back to the time when Andrew Murray Jr ministered in the DRC Wellington (1871â€“1906). It is well known that under Murrayâ€™s leadership the Wellington congregation and community played a leading role in the awakening of missionary work by the DRC as well as social development, and the fourth section alludes briefly to some characteristics of Murrayâ€™s spirituality. The article concludes with a suggestion that the evangelical piety (De Gruchy, 2009:221) of Andrew Murray Jr may be regarded as an early form of missional spirituality.
Green parables, biodiversity, and ecological understanding of Sperma in Matthew 13:3–9
Authors: Uzukwu Gesila Nneka
Published: August 2023

Reading Matthew’s Gospel ecologically, scholars have investigated several dimensions of Matthean ecological conversations and have provided interesting insights into the ecological agenda of the gospel. Despite the contributions, studies have paid little attention to Matthean theology of biodiversity, the green nature of the parables, and the central importance of sperma (seed) as embodying the entirety of divine ecological revelation of God’s words and the ecological theology of Matthew. Exploring how Matthean ecological discourses call for new perspectives on our ecological crises, this article engages the parable of the sower from the perspective of the green nature of the parable, biodiversity, and the use of sperma as the centrality of God’s ecological/spiritual revelation. Its aim is to present new creative discourses for the ecological study of the Gospel of Matthew and offer an understanding of the parable from an ecological approach that can help us engage with our present environmental crises.
Investigate Advanced Approaches on Direct Current Solid-State Circuit Breakers
Authors:   , Kheirollahi Reza , Lu Fei
Published: August 2023

Direct current (dc) power systems are gaining more attention in academia and industry due to their advantages compared with conventional alternating current (AC) power networks. DC systems present higher efficiency at the same voltage levels, they need no frequency synchronization and reactive power compensation, and they ease the integration of renewable energies. Despite the advantages of dc power systems, there are still several technical and practical challenges that slow down their widespread adoption and development worldwide. One of the primary technical challenges that must be addressed is the development of dc circuit breakers (DCCBs). Among DCCBs, dc solid-state circuit breakers (SSCBs) use semiconductor devices to conduct load currents during the normal operation and hold dc bus voltages during the breaker OFF-state. Among many benefits, SSCBs present an ultrafast response speed, a modular structure, no arc problems, extended operation cycles, and a high compactness, fulfilling the urgent needs of emerging technologies such as electric ships. However, solid-state switches used in SSCBs have limited voltage/current turn-off capability and thermal capacity, requiring more investigations in the field. This thesis focuses on advanced techniques to enhance lifetime, safety, and reliability in dc SSCBs. There are four main contributions as follows. Firstly, soft turn-off dc SSCBs are introduced, where compact and fast active injection circuits (AIC) are used to eliminate the transient energy and mitigate gate voltage oscillations in solid-state switches during current interruption, extending the SSCBs lifetime. Second, active snubbers in dc SSCBs are discussed, and novel topologies are presented to extend the maximum allowable dc bus voltage on SSCBs, remove the voltage on passive components during the SSCBs OFF-state, and solve the reliability issue of varistors in SSCBs. Next, fault current bypass-based dc SSCBs are proposed, where fault currents are reduced to zero at the load side or faulty sections within microseconds regardless of the dc system's line inductance, improving safety. Finally, SSCBs are studied at the system-level, and a new protective scheme is developed to optimally coordinate dc ultrafast SSCBs in multi-source dc microgrids. In summary, dc SSCBs play a key role in newly established dc power systems. SSCBs present a fast response speed, a modular structure, and high compactness. In this thesis, advanced techniques are introduced to improve lifetime, safety, and reliability in dc SSCBs at device- and system-level.
Security of Bluetooth Low Energy Internet of Things Devices
Authors:   , Thornton Zachary , Mancoridis Spiros , Weber Steven P.
Published: August 2023

The goal of this work was to better understand the state of security in Bluetooth Low Energy (BLE) Internet of Things (IoT) devices. This was accomplished by creating malicious code and testing a few known attacks. Code was created to attempt a denial of service (DoS) attack on an IoT gateway, and malware was developed to exfiltrate data. The malware was designed for two functions. First, it read data being sent to the gateway via a BLE IoT sensor. Afterwards, it choose whether or not to exfiltrate it based on a user defined parameter. A detector was also built to measure the malware's effectiveness in stealthy operation. The effectiveness of the detector was then compared against the percentage of exfiltrated data. The results of the DoS attacks showed difficulty in successfully performing them, whereas the results for the exfiltration malware show that at low percentages of data exfiltration, detection is difficult. After a small amount of exfiltration (about 4%) however, detection accuracy dramatically increases by almost 40%. This is likely due to how easy it is to detect anomalous behavior when a benign system is relatively quiet or consistent in operations.

Uso de Jogos Digitais no Ensino de Química Orgânica: um Relato de Experiência
Authors: Vieira Mariana de Lourdes Almeida , Faria Júnior Célio Nogueira de
Published: August 2023

Jogos digitais podem desempenhar um importante papel como mediadores do processo de construção do conhecimento no ensino de Ciências. O uso deste recurso tecnológico, que agrega fatores como diversão, prazer, habilidades e conhecimentos, vem crescendo nas últimas décadas. Apesar de os documentos oficiais propostos para a Educação Básica brasileira orientarem a utilização de atividades lúdicas, não há diretrizes de como esse trabalho deve ser pedagogicamente estruturado. Neste contexto, o objetivo deste estudo foi avaliar como o jogo digital My Química Lab pode contribuir para a aprendizagem de Química Orgânica, investigando-se as contribuições propiciadas pela experiência com o jogo por meio da análise da percepção de estudantes do ensino médio ao usar este recurso. A partir dos dados obtidos por meio de observações e questionários, foi possível verificar que o jogo auxiliou na compreensão e no aprendizado de conceitos relacionados à Química Orgânica, além de ter revelado o interesse dos estudantes em participar de atividades lúdicas durante as aulas. Ressalta-se ainda que desenvolver e selecionar jogos digitais que possam ser utilizados para o ensino de Ciências se apresenta como um grande desafio ao professor. Resultados satisfatórios relacionados à esta prática dependem não somente do jogo em si, mas como também da forma como o docente planeja e conduz esta atividade.

AbstractDigital games can play an important role as mediators in the knowledge construction process in Science Education. The use of this technological resource, which adds factors such as fun, pleasure, skills and knowledge, has grown in recent decades. Although the official documents proposed for Basic Education in Brazil guide the use of recreational activities, there are no guidelines on how this work should be pedagogically structured. In this context, the objective of this study was to evaluate how the digital game My Química Lab can contribute for the learning of Organic Chemistry, investigating the contributions provided by the experience with the game through the analysis of high school students perception when using this resource. Considering the data obtained through questionnaires and observations, it was possible to verify that the game helped students to understand and learn concepts related to Organic Chemistry, and revealed their interest in participating in ludic activities during the classes. It is also noteworthy that developing and selecting digital games that can be used for Science Teaching is a challenge to the teacher. Satisfactory results related to this practice depend not only on the game itself, but also on the way the teacher plans and conducts this activity.

The research presents the results of a quantitative survey of senior managers’ evaluation of proficiency of employees’ social skills completed in 2019 within the framework of the Next Tourism Generation Alliance, a European Commission funded project. The current and future levels of proficiency, social skills gaps and training are assessed. The sample includes 1404 respondents from organisations across eight countries in Europe in five tourism and hospitality sectors (hospitality, food & beverage, tour-operators, visitor attractions and DMOs). Results show significant country-based differences and variations according to the type of organisation, operational sector and organisation size. The required future levels of the social skills are strongly related to their current levels. Two clusters are identified based on the management perceptions of employees’ social skills gaps. Respondents in the first cluster (N=871) see only small gaps between the current and required future proficiency levels of social skills in their organisations while respondents in the second cluster (N=533) perceive much larger gaps. The findings indicate a need to develop holistic social skill training and education which supports quality customer experiences and sustainable tourism criteria.

Authors: ARSLAN Kutbettin
Published: August 2023

Food spoilage pathogens cause food waste and consumption of pathogen-contaminated food threatens human health. New approaches that do not harm the environment are needed for decreasing the enlargement of pathogenic microorganisms without using chemical preservatives. The current work intended to appraise the TPC value, anti-oxidant, anti-bacterial, and anti-fungal properties of clove different extracts. The antimicrobial tests were evaluated by disc diffusion, MIC, and MBC tests. Antioxidant potential was conducted using ABTS• and DPPH• radical, and TPC was tested by the Folin–Ciocalteu reagent assay. As a result, the highest antimicrobial activity was found against E. faecalis by 19,30±0,17 mm zone diameter from methanol extract. The lowest activity was obtained from aqueous extract over S. Typhimurium by 7,17±0,29 mm zone diameter. MIC and MBC results were examined, and it was determined that clove ethanol extract showed the highest MIC value was 2.5-10 mg/ml. MBC test results also revealed that cloves ethanol extract has the highest activity with 5->10 mg/ml. The antioxidant data of cloves were examined, and the highest DPPH• and ABTS• sweep activities were determined in 60.93±1.67% aqueous and 85.81±1.08 ethanol extract, respectively. The TPC results revealed that the highest content was provided from the aqueous extract with 189.84±2.84 mg/g GA. The results gained from the study bring to light that clove has a high potential for antimicrobial, antioxidant, and total phenolic content.

Background: Cardioplegia is used to induce and provide a depolarized diastolic cardiac arrest to provide a motionless surgical field. Del Nido cardioplegia solution has been used extensively in congenital heart surgery for more than 20 years and more recently for adults. This observational study was performed to assess the safety and efficacy of del Nido cardioplegia in adult cardiac surgery patients.
Methods: Total 140 adult patients selected for cardiac surgical procedure i.e., coronary artery bypass grafting (CABG), valve surgery, or CABG with valve surgery no need requiring cardiopulmonary bypass (CPB) were purposively allocated into two groups: a) del Nido cardioplegia (n=70) and b) blood cardioplegia (n=70). Primary outcomes assessed myocardial preservation.
Results: The study compared del Nido (A) and blood cardioplegia (B) groups. Mean ages were 49.5±7.86 and 48.9±6.79 years, respectively (p=0.5641). BMI (26.98±2.3 vs 27.2±2.14 kg/m2, p=0.4846) and comorbid factors, including smoking (48% versus 51%) were similar. Differences were lower hemoglobin in A (males: 11.7±1.18 versus 13.6±0.55; females: 10.2±0.58 versus 12.2±0.21, p<0.0001) and CPB/ACC times for isolated CABG (A: 112.40±15.75/78.45±11.65 versus B: 123.8±18.55/86.28±15.26 minutes, p=0.0001). Post-operatively, more blood loss occurred in A, but they had shorter mechanical ventilation, ICU stay, and hospital stay durations. Other variables, like 30-day mortality, were similar.
Conclusions: Evidence from this study suggests del Nido cardioplegia use in routine adult cases may be safe, result in comparable clinical outcomes, and streamline surgical workflow. The trend for troponin should be investigated further because it may suggest superior myocardial protection with the del Nido solution.

O objetivo do trabalho foi estudar o efeito de hidrofugantes e cristalizantes aplicados ao concreto, através da realização dos ensaios de resistência à compressão axial (NBR 16.889, 2020), absorção de água por imersão (NBR 9778, 2009) e absorção de água por capilaridade (NBR 9779, 2012). Os resultados sugerem a interferência do aditivo impermeabilizante nas propriedades mecânicas do concreto, causando queda de 37% da resistência de concretos produzidos com aditivo hidrofugante e 28% para concretos com adição de cristalizantes. No que diz respeito à estanqueidade, os resultados indicam pouca eficácia dos aditivos impermeabilizantes, em que se obteve 7,83% da redução da absorção com o uso de aditivos cristalizantes e, até mesmo, aumento de 1,44% da absorção com o uso de aditivos hidrofugantes.

AIM: To evaluate the effects of LIN28A (human) on high glucose-induced retinal pigmented epithelium (RPE) cell injury and its possible mechanism.
METHODS: Diabetic retinopathy model was generated following 48h of exposure to 30 mmol/L high glucose (HG) in ARPE-19 cells. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot tested the expression of the corresponding genes and proteins. Cell viability as well as apoptosis was determined through cell counting kit-8 (CCK-8) and flow cytometry assays. Immunofluorescence assay was adopted to evaluate autophagy activity. Caspase 3 activity, oxidative stress markers, and cytokines were appraised adopting their commercial kits, respectively. Finally, ARPE-19 cells were preincubated with EX527, a Sirtuin 1 (SIRT1) inhibitor, prior to HG stimulation to validate the regulatory mechanism.
RESULTS: LIN28A was downregulated in HG-challenged ARPE-19 cells. LIN28A overexpression greatly inhibited HG-induced ARPE-19 cell viability loss, apoptosis, oxidative damage as well as inflammatory response. Meanwhile, the repressed autophagy and SIRT1 in ARPE-19 cells challenged with HG were elevated after LIN28A overexpression. In addition, treatment of EX527 greatly inhibited the activated autophagy following LIN28A overexpression and partly abolished the protective role of LIN28A against HG-elicited apoptosis, oxidative damage as well as inflammation in ARPE-19 cells.
CONCLUSION: LIN28A exerts a protective role against HG-elicited RPE oxidative damage, inflammation, as well as apoptosis via regulating SIRT1/autophagy.
