This project seeks to highlight the benefits of the implementation and management of the teaching digital portfolio. In today's world full of technology and tools that facilitate daily activities, education and its various processes must also embrace the digital tools available and make them the basis for any innovation and improvement process. The teaching portfolio in physics has long been the means by which teachers have organized the processes, evidence, and other results of educational work. Nowadays, all that range of (...) evidence and productions, which signify the achievement and advances in each group of students, has been able to be integrated into technology. (shrink)

Ezzence is the first smartphone-controlled olfactometer designed for both day and night conditions. We discuss the design and technical implementation of Ezzence and report on a study to evaluate the feasibility of using the device in home-based sleep environments. The study results show that participants were satisfied with the device and found it easy to use. Furthermore, participants reported a significant improvement in sleep quality when using the device with scent in comparison to the control condition, as well as better (...) mood the following morning and shorter time to sleep onset. The device is integrated with a wearable EEG and real-time sleep staging algorithm to release scent during specific sleep stages, which is important for certain use cases. Ezzence can be used for several applications, including those that require scent triggered day and night. They include targeted memory reactivation, longitudinal health treatments, therapy, and mental or physical exercises. Finally, this article proposes an interaction framework to understand relationships between scents and environments based on proxemic dimensions and passive or active interactions during sleep.

Nada propone una interpretación de las diferentes conciencias (arcaica, mágica, mítica, mental e integral) que han ocupado los distintos eones que ha atravesado nuestra especie (urobórico, tifónico, matriarcal, patriarcal y fratriarcal), partiendo de que en todas ellas se ensayan diversos tratos con la nada o lo indeterminado. Se sugiere que, en cada eón, la respectiva conciencia pasa por una fase de ignorancia negativa (no sabe que no sabe), otra de ignorancia positiva (sabe que no sabe), un momento de impasse en (...) el que el decaimiento de una conciencia se cruza con la emergencia de otra, resultando de tal cruce un conocimiento inconsciente (no sabe que sabe), y un momento final de conciencia plena o sabiduría (sabe que sabe) desde el que se precipitan, de nuevo, pero en otro eón y sobre otra conciencia, nuevas ignorancias.
