This paper discusses several practical activities carried out in the subject Philosophy of Law in which the values of freedom, equality, legal certainty, and solidarity were considered in connection with different circumstances experienced during the COVID-19 pandemic. The activities addressed topics such as legal mask mandates, the prioritization of certain groups in the vaccination strategy, language issues with some of the precepts related to the lockdown, regulatory instability in the regulation of mask use, or the distribution of vaccines for people in low-income countries. Students were assessed on the content through written tests and class participation. In light of the implementation of the experiences, as well as students’ perceptions of them, it can be concluded that they deliver additional knowledge, enable training in various competencies, arouse interest, and facilitate better understanding of the theoretical content taught., Este trabajo recoge varias prácticas realizadas en la asignatura de Filosofía del Derecho, en torno a los valores de la libertad, la igualdad, la seguridad y la solidaridad, que se han considerado a propósito de diferentes circunstancias vividas durante la pandemia del COVID-19. En estas actividades se abordan temas como la obligación de llevar mascarillas establecida normativamente, la prioridad otorgada a determinados colectivos en la estrategia de vacunación, los problemas lingüísticos de algunos preceptos relativos al confinamiento, la inestabilidad normativa en la regulación del uso de las mascarillas, o la escasez de vacunas para las personas que viven en países pobres. Los contenidos tratados han sido objeto de evaluación en pruebas escritas, y también en las participaciones desarrolladas en clase. Teniendo en cuenta la implementación de las experiencias, así como la percepción del alumnado sobre ellas, puede afirmarse que contribuyen a aportar más conocimientos, hacen posible el entrenamiento en diferentes competencias, suscitan el interés y ayudan a entender mejor los contenidos teóricos impartidos.

This paper describes a teaching innovation experience implemented in the subject Philosophy of Law, based on the content taught on utilitarianism and deontological theory. The objectives were, amongst others, to clarify the content, provide lasting learning, and prompt reflection and critical thinking in students. The actions were mainly carried out in the practical sphere, using situations depicted in film scenes in which technological advances pose various dilemmas. Students were asked to diagnose these circumstances, identify the theory or theories of justice at play in them, and take a position. This exercise gave rise to various criticisms of the theories of justice in question; the students had to verify these objections, which thus became part of the subject’s content. The results obtained were generally satisfactory, as confirmed by a subsequent student survey. The level of achievement of the defined objectives suggests that the actions should continue to be implemented in future, offering the opportunity to improve them with other aspects that could help complete the training., Este trabajo recoge una experiencia de innovación docente implementada en la asignatura de Filosofía del Derecho, partiendo de los contenidos impartidos sobre el utilitarismo y la teoría deontológica. Entre los objetivos que se pretenden están los de clarificar contenidos, proporcionar un aprendizaje duradero, y motivar la reflexión y el pensamiento crítico en el alumnado. Las acciones se desarrollan principalmente en el ámbito práctico, a partir de determinadas situaciones recogidas en escenas cinematográficas, en las cuales los avances tecnológicos suscitan varios dilemas. El alumnado debe realizar un diagnóstico de estas circunstancias, localizar en ellas la teoría o teorías de la justicia en juego, y adoptar una toma de postura. De este desarrollo se derivan varias críticas dirigidas a las teorías de la justicia en cuestión; se trata de objeciones que el alumnado debe constatar y que pasan a formar parte de los contenidos de la asignatura. Los resultados obtenidos son satisfactorios en términos generales; así lo confirma una encuesta realizada por el alumnado. Como conclusión cabría señalar que el nivel de consecución de los objetivos establecidos invita a seguir implementando las acciones en el futuro, siendo ello una oportunidad para mejorarlas con otros aspectos que pueden contribuir a completar la formación.

Smartphones are powerful tools with extensive sensorization that can provide useful information in research or everyday life applications. This information can be obtained from the device's built-in sensors or through other external sensors connected physically via USB or wirelessly via Bluetooth or WiFi. This paper presents the GetSensorData application that provides an open-source, flexible and extensible framework for registering sensor data from Android devices. The application uses standard formatting and synchronization, easing interoperability with other software. End developers (particularly those involved in research) can save the effort and time of creating their sensor acquisition applications and fully concentrate on the higher-level data processing tasks. The application has been used and successfully evaluated for six years by various research groups in different activities related to their work areas. Some examples are the calibration of positioning systems in competitions held at conferences, modeling wireless signal path loss propagation in indoor environments or data collection for unsupervised learning algorithms.

In the elderly, geriatric problems such as the risk of fall or frailty are a challenge for society. Patients with frailty present difficulties in walking and higher fall risk. The use of sensors for gait analysis allows the detection of objective parameters related to these pathologies and to make an early diagnosis. Inertial Measurement Units (IMUs) are wearables that, due to their accuracy, portability, and low price, are an excellent option to analyze human gait parameters in health-monitoring applications. Many relevant gait parameters (e.g., step time, walking speed) are used to assess motor, or even cognitive, health problems in the elderly, but we perceived that there is not a full consensus on which parameters are the most significant to estimate the risk of fall and the frailty state. In this work, we analyzed the different IMU-based gait parameters proposed in the literature to assess frailty state (robust, prefrail, or frail) or fall risk. The aim was to collect the most significant gait parameters, measured from inertial sensors, able to discriminate between patient groups and to highlight those parameters that are not relevant or for which there is controversy among the examined works. For this purpose, a literature review of the studies published in recent years was carried out; apart from 10 previous relevant reviews using inertial and other sensing technologies, a total of 22 specific studies giving statistical significance values were analyzed. The results showed that the most significant parameters are double-support time, gait speed, stride time, step time, and the number of steps/day or walking percentage/day, for frailty diagnosis. In the case of fall risk detection, parameters related to trunk stability or movements are the most relevant. Although these results are important, the total number of works found was limited and most of them performed the significance statistics on subsets of all possible gait parameters; this fact highlights the nee
