In the early 90's, and especially in some American universities, with the emergence of virtual reality, virtual environments and their manipulation began to be implemented, achieving important advances that have led to improvements in research through changes in the perception of the subject, modeling, communication processes and the development of 3D virtual classrooms. These advances have led to the metaverse, as an environment where humans interact socially as avatars, and especially its application in the world of education in the fields of entertainment, tele-education, educational research, learning environments, etc. According to technologists, this year will separate the thinkers from the builders, and then the technical advances of the last few years will produce the first steps this year in making the metaverse a reality. Advances will largely be attributed to ever-better graphics processing units (GPUs), photorealistic 3D engines, faster content generation through volumetric video and artificial intelligence, the increasing prevalence of cloud computing and 5G, as well as a more sophisticated and better understood blockchain infrastructure. But from a human experience perspective, one development stands out above all others: extended reality (XR) technologies. These include virtual reality (VR), augmented reality (AR) and brain-computer interfaces (BCI), which together are positioned as the next computing platforms in their own right.

RESUMENLa Unidad Prototipo de Vivienda de Emergencia (UPVE) es el resultado del Proyecto de Investigación Aplicada VEM (Vivienda de Emergencia Militar) desarrollado con la colaboración de la Escuela Politécnica Superior de la Universidad CEU y la empresa Airbus Defense & Space. Es concebido como una unidad modular e industrializable de habitabilidad básica, de crecimiento programado y extensible, diseñada para proporcionar refugio y protección en entornos de crisis humanitaria o en contingencias de vulnerabilidad social con el fin de asegurar un hábitat sostenible de emergencia.La influencia que los procesos de construcción y materiales involucrados en la fabricación de dicha UPVE tienen en el medio ambiente, analizados mediante la metodología de Análisis de Ciclo de Vida (ACV), consideran especialmente crítico el reciclado de los materiales utilizados. Así, con el objetivo de analizar y disminuir el impacto medioambiental, se cuantifican cada una de las partes que componen la Unidad Prototipo desarrollada, valorando los beneficios resultantes de los procesos de fabricación en la disposición final de los materiales según la metodología DfMA (Design for Manufacturing and Assembly).Palabras clave: ACV; Vivienda de Emergencia Militar; construcción sostenible; DfMA.

We are in a society where news travels like wildfire. The COVID-19 pandemic has forced us to reorder our space and time. This article analyses these changes and puts the human race in the face of possible pandemics that are to come. Nowadays, we live in a world outside the normality to which we want to return as soon as possible. Reality shows that many things have changed, and we do not know very well if they are to stay. Concern for health workers has grown in all countries, their great need has been shown in cases like this, and the worst thing is that according to the statistics, the world will be subjected to pandemics of this kind in the coming years. Finding a vaccine or drug capable of fighting, stopping and defeating it is a challenge for the world in general, and science and scientists in particular. This study also shows the struggle of the best scientific centres, and the different paths they have taken, to reach the goal first. Cooperation between all health agencies has become a priority, now more than ever, efforts are being made to achieve the same goal, to get the COVID-19 vaccine. Let us hope that science has arguments to win this battle, the war is still to come.
