Towards the Integration of Emerging Technologies as Support for the Teaching and Learning Model in Higher Education

The pandemic caused by COVID-19 impacted the entire world, but the significant challenges to be faced during this crisis opened an opportunity for organizations to evolve toward a digital transformation. Educational institutions were a concrete example of the use of technologies, which were abruptly incorporated into the teaching–learning model. Although this initiative was initially a challenge for teachers and students, it has now become a tool for new innovative teaching models, such as hybrid, online, and flexible models. The impact of technology used in education has been beneficial due to emerging technologies (virtual reality, augmented reality, games, web applications, mobile applications, etc.), which have served as tools to facilitate and motivate studying. These educational trends contribute directly to the fourth Sustainable Development Goal (SDG). This research analyzes whether the use of a web application, as a support in the educational model, can make students better understand the subjects of network infrastructure and be more efficient when configuring equipment in a data network. Therefore, this research is based on the design of an educational web application based on Python libraries, which allows the configuration of networking equipment based on the concept of network automation with the application of a graphical user interface (GUI). The web application can be deployed with communication equipment or in conjunction with the GNS3 simulator. This versatility allows this web tool to be applied to the teaching of network equipment configuration in any mode of study (classroom, online, hybrid, or flexible). The results obtained in this research are encouraging and open the way for the implementation of network automation and Python libraries for educational applications that can be important tools within the teaching and learning models of higher education.This work was financed by the Universidad de Las Américas through project code: TIC.LCC.22.01

Estudio de canteras históricas de Ferriol. Valoración de su utilización como piedra de sustitución en Stª Maria de Elche

La piedra predominante en la fábrica de la Basílica de Santa María de Elche es la biocalcarenita, empleándose diferentes variedades en cada una de las fases constructivas. La más alterada y objeto de este artículo, es la que conforma la Capilla de la Comunión, obra del siglo XVIII de gran valor arquitectónico y que en un futuro cercano debería ser objeto de restauración. Las indagaciones históricas han sacado a la luz un documento de 1759 firmado por uno de los arquitectos autores de la Basílica de Santa María en Elche, donde se indica el número y formato de los sillares, y de donde se debían extraer dichos materiales. En el término de Elche, hay un paraje denominado Ferriol cuyas rocas han sido explotadas como piedra de construcción durante varios siglos y diferentes culturas, estando datada al menos una de las canteras allí desarrolladas en época íbera. Se han tomado muestras en tres antiguos frentes de cantera, situándolos litoestratigráficamente y se han comparado con los del propio edificio. Para ello se ha realizado un estudio mineralógico, petrográfico y petrofísico. Uno de los frentes muestreados corresponde a la cantera íbera mencionada, de donde podría haber sido extraída la piedra empleada en la escultura de “La Dama de Elche”. La biocalcarenita obtenida en la cantera del Ferriol es semejante a la de la Capilla de la Comunión, con una densidad aparente del orden de 1,8 g/cm3, la porosidad sobre el 20%, el coeficiente de capilaridad es 74 g/m2 s0.5 y la resistencia a compresión de 17,6 MPa

Necrolytic migratory erythema associated with glucagonoma syndrome: a case report Eritema necrolítico migratório associado à síndrome glucagonoma: descrição de um caso

Necrolytic migratory erythema is a rare skin condition that consists of migrating areas of erythema with blisters that heal with hyperpigmentation. It usually occurs in patients with an alpha islet cell tumor of the pancreas-or glucagonoma-and when associated with glucose intolerance, anemia, hyperglucagonemia, and weight loss defines the glucagonoma syndrome. We describe a 52-year-old female patient with necrolytic migratory erythema associated with glucagonoma syndrome who had metastatic disease at presentation and passed away one week after her admission. The autopsy showed a tumor in the body of the pancreas, which was diagnosed as a neuroendocrine tumor and confirmed by immunohistochemistry. The diagnosis of necrolytic migratory erythema is a matter of great importance, since it might be an auxiliary tool for the early detection of glucagonoma.<br>O eritema necrolítico migratório é uma rara condição cutânea que se apresenta como lesões eritematosas, migratórias, com vesículas e bolhas na superfície, evoluindo para cura com hiperpigmentação. É freqüentemente observado em doentes com tumor de células alfa do pâncreas, ou glucagonoma, e quando associado com intolerância a glicose, anemia, hiperglucagonemia, e perda de peso definem a síndrome do glucagonoma. É descrito o caso de uma paciente do sexo feminino, 52 anos, branca, com eritema necrolítico migratório associado à síndrome do glucagonoma com doença metastática na apresentação, vindo a falecer uma semana após sua admissão. A autópsia mostrou um tumor no corpo do pâncreas diagnosticado como tumor neuroendócrino e confirmado pela imuno-histoquímica. O reconhecimento do eritema necrolítico migratório é de grande importância para a possibilidade de diagnóstico precoce do glucagonoma
