El uso y acceso a las tecnologías de la información y comunicación se ha convertido en una realidad. Actualmente hay casi más teléfonos que personas, además desde edades tempranas se utilizan múltiples pantallas y se accede a Internet. Frente a esta realidad, conviene reflexionar sobre la necesidad de que dos disciplinas de antaño separadas: la educación y la comunicación, aúnen sus esfuerzos para que la totalidad de la ciudadanía esté alfabetizada. En este sentido, resulta fundamental que no solo el profesorado sino también las familias alcancen un mínimo desarrollo de la competencia digital que les permita enseñar a los menores a utilizar adecuadamente los dispositivos digitales. Asimismo, y pese a la inexistencia de políticas educativas claras que amparen la educomunicación como un contenido curricular ni en el contexto español ni en el gallego, se cuenta con inicia...

Perú se ubica en el Cinturón de Fuego del Pacífico, una región caracterizada por una intensa actividad sísmica y un alto riesgo de erupciones volcánicas. Dentro de este contexto, el Volcán Misti destaca por ser clasificado como de alto riesgo, debido tanto a su actividad volcánica continua como a la proximidad de una densa población, que se estima en alrededor de 1 millón de habitantes. Esta situación ha motivado el monitoreo constante del volcán, inicialmente a cargo del Observatorio Vulcanológico del Instituto Geológico, Minero y Metalúrgico (INGEMMET) durante la última década, y, a partir de 2021, por el Centro Nacional Vulcanológico (CENVUL) del Instituto Geofísico del Perú (IGP).El estudio y monitoreo de la actividad volcánica resultan fundamentales, no solo por el valor científico de comprender los procesos geológicos, sino también por la importancia humanit...

Contemporary university work cannot be understood without computer applications, and they must be used without their pedagogical use altering the essence and purpose of educating people integrally. Technology facilitates access to knowledge and communication, but inappropriate use can be harmful, which requires training in solid bioethical criteria to avoid harmful decisions that may be detrimental to the people they will serve in the future exercise of their profession. Ethics, in its various forms (metaethics, normative ethics, ethics of minimums, among others), offers frameworks to address dilemmas related to technology in university education, promoting informed and responsible decisions. Bioethics, with approaches such as personalist, principlist, virtue bioethics, ecological and pragmatic, emphasizes the importance of human dignity and environmental sustainability in the academic c...
