A technological table of a steel gathers various technological data as well as a series of diagrams that allow the manufacturer and the user to obtain the desirable properties in order to guarantee the commissioning of said steel. Therefore, the technological table is a complement to the classification table that classifies steels according to their chemical composition and the Standard that indicates the minimum characteristics that must be obtained with a previously established treatment. The determination of the different data that make up this table is simple and is within the reach of any laboratory or a small metallurgical industry. It should be remembered that technological data are usually indicative, given the different behavior of different castings of the same type of steel and the normal limitations of the test methods, only a statistical study will be able to reflect the rea...

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...

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...

An unplanned health care system is like a paper boat carried by a slowly sinking current. In times of disinformation and excessive distraction, investing in better facts on health technology assessment (HTA) will enable more active actions rather than reactive to the market dynamics. This paper aims to raise some reflections on HTA in terms of political context, health technologies and epidemiological priorities. The perspective of HTA is context dependent, intrinsic to its political and institutional articulation. At the moment, the paradox is to maintain a specialized structure in the face of economic austerity policies that reduce health resources, and a scenario of greater interest in raising public funds by the private sector. Particularly in Brazil, HTA will also have to deal with the gradual shift from a universal health system to a minimum portfolio of services offered by the pri...
