Recibido: 26 de mayo del 2016/ Enviado a evaluar: 6 de junio del 2016/ Aceptado: 18 de julio del 2017Resumen. En el presente trabajo se han estudiado las percepciones y actitudes sobre la energía sostenible en un grupo de estudiantes de 2º y 4º de ESO de dos centros escolares de la Comunidad de Madrid. La herramienta para recabar la información necesaria ha consistido en un cuestionario abierto preparado a partir de la literatura. Además, con uno de los grupos se ha llevado a cabo una propuesta didáctica atractiva y dinámica basada en la columna de Winogradsky como paso previo hacia las pilas de combustible microbianas, aprovechando la declaración de 2014 como el año de la Biotecnología en España. Esta propuesta puede servir de referencia a los docentes para reforzar y extender contendos de Física, Química y Biología en el marco de una Educación Ambiental responsable y comprometida en Educación Secundaria. Transversalmente, aunque no por eso menos importante, se ha pretendido con la propuesta aumentar el interés hacia las ciencias experimentales y despertar nuevas vocaciones científicas entre los discentes.

In this work, it has been studied the perceptions and attitudes about sustainable energy of two groups of students (2 nd and 4 th year of Secondary Education) of the Community of Madrid. The datacollection tool has consisted of an open questionnaire prepared based upon the literature. In addition, it has been performed an attractive and dynamic school activity based on the Winogradsky column as a previous work of the microbial fuel cells-taking into account that 2014 was declared the year of Biotechnology in Spain. This proposal may be considered a reference point for teachers who want to reinforce and extend content of Physics, Chemistry and Biology in the framework of a responsible and committed Environmental Education in Secondary Education. Transversely but not least, we have tried with this proposal to increase the interest in the experimental sciences and encourage new scientific vocations among the students.

IntroductionStroke is a leading cause of severe and long-term disability in developed countries. Around 15 million people suffer a stroke each year, most due to modifiable risk factors. Several reviews have shown that interventions mediating eHealth technologies can reduce the risk of suffering a stroke episode, improving the control of risk factors; nevertheless, all of them conclude that new and well-designed studies are needed.MethodsWe performed a prospective, randomized, parallel group and open, pilot trial. The study was carried out based on an initial sample of forty-three patients between 18 and 80 years old who have had an ischemic stroke. The control group got conventional treatment and the intervention group got conventional treatment and the assistance of STARR (the Decision SupporT and self-mAnagement system for stRoke survivoRs), as well as commercial wearables. The principal variable of the study was to evaluate the usability of the decision support system.ResultsAt month nine, the average score on the System Usability Scale in the intervention group was 64.7 and in month 12, 67.4, exceeding in both cases the margin of acceptability (50) and in the limit of “good” (68). When we analyzed clinical factors (systolic/diastolic blood pressure) as well as the analytical parameters related to prevention of reinfarction, we observed that the intervention group had good control of blood pressure and better analytical parameters, compared to the control group.ConclusionsTechnological support allowed participants to feel comfortable using the devices as well as resolving technical incidences by themselves after a training period. The self-management platform can be efficient in stroke survivors’ management of their disease condition, improving analytical and clinical parameters, which eventually can influence a decrease in associated comorbidities and, therefore, improvement of the disease. However, it should be noted that this type of platform is not useful for every patient profile, and studies in this regard should be expanded.
