This paper presents a vaccination strategy for fighting against the propagation of epidemic diseases. The disease propagation is described by an SEIR (susceptible plus infected plus infectious plus removed populations) epidemic model. The model takes into account the total population amounts as a refrain for the illness transmission since its increase makes the contacts among susceptible and infected more difficult. The vaccination strategy is based on a continuous-time nonlinear control law synthesised via an exact feedback input-output linearization approach. An observer is incorporated into the control scheme to provide online estimates for the susceptible and infected populations in the case when their values are not available from online measurement but they are necessary to implement the control law. The vaccination control is generated based on the information provided by the observer. The control objective is to asymptotically eradicate the infection from the population so that the removed-by-immunity population asymptotically tracks the whole one without precise knowledge of the partial populations. The model positivity, the eradication of the infection under feedback vaccination laws and the stability properties as well as the asymptotic convergence of the estimation errors to zero as time tends to infinity are investigated.

Clubhouse Euskadi es una propuesta innovadora en el campo de la Educación Social, concretamente en el ámbito de la enfermedad mental. Se trata de un modelo de rehabilitación psicosocial que promueve la inclusión social de las personas en un clima de trabajo, para alcanzar la autonomía propia de las mismas. Ésta se logra mediante la organización de un centro diurno, basado en un trabajo colaborativo e igualitario entre sus miembros y profesionales, que fomentan el acceso a empleos de transición e incluso independientes. La educación y el ocio son, a su vez, componentes esenciales que influyen en el periodo de mejora.

The HIV (Human Immunodeficiency Virus) is a very important disease in the world, with approximately 35 million people infected. In this study we have tried to expose the main characters of the virus, explaining the disease and the illness associated to the HIV. Besides, we have explained the antiretroviral treatments that are the most important weapon against the HIV. However, any of these treatments do not eliminate the HIV in the human body. For this reason, we have been looking for the new treatments and researches that have been development in the last years, including vaccines and genetic resistance. In addition, we have described the situation of the SIV (Simian Immunodeficiency Virus) in Africa, because it is the origin of the disease. The prevalence of the virus in primates population is something that have being studied for the last years, because it could be a new threat to the human population. Finally, we have proposed the researches lines that seems to be more effective and the ones that, in a future, could eliminate the virus in the human body.
