Heart Failure Monitoring System Based on Wearable and Information Technologies

In Europe, Cardiovascular Diseases (CVD) are the leading source of death, causing 45% of all deceases. Besides, Heart Failure, the paradigm of CVD, mainly affects people older than 65. In the current aging society, the European MyHeart Project was created, whose mission is to empower citizens to fight CVD by leading a preventive lifestyle and being able to be diagnosed at an early stage. This paper presents the development of a Heart Failure Management System, based on daily monitoring of Vital Body Signals, with wearable and mobile technologies, for the continuous assessment of this chronic disease. The System makes use of the latest technologies for monitoring heart condition, both with wearable garments (e.g. for measuring ECG and Respiration); and portable devices (such as Weight Scale and Blood Pressure Cuff) both with Bluetooth capabilities

Estimación del riesgo sísmico en puerto príncipe (Haití)

Tras el devastador terremoto del 12 de enero de 2010 en Puerto Príncipe, Haití, las autoridades locales, numerosas ONGs y organismos nacionales e internacionales están trabajando en el desarrollo de estrategias para minimizar el elevado riesgo sísmico existente en el país. Para ello es necesario, en primer lugar, estimar dicho riesgo asociado a eventuales terremotos futuros que puedan producirse, evaluando el grado de pérdidas que podrían generar, para dimensionar la catástrofe y actuar en consecuencia, tanto en lo referente a medidas preventivas como a adopción de planes de emergencia. En ese sentido, este Trabajo Fin de Master aporta un análisis detallado del riesgo sísmico asociado a un futuro terremoto que podría producirse con probabilidad razonable, causando importantes daños en Puerto Príncipe. Se propone para ello una metodología de cálculo del riesgo adaptada a los condicionantes de la zona, con modelos calibrados empleando datos del sismo de 2010. Se ha desarrollado en el marco del proyecto de cooperación Sismo-Haití, financiado por la Universidad Politécnica de Madrid, que comenzó diez meses después del terremoto de 2010 como respuesta a una petición de ayuda del gobierno haitiano. El cálculo del riesgo requiere la consideración de dos inputs: la amenaza sísmica o movimiento esperado por el escenario definido (sismo de cierta magnitud y localización) y los elementos expuestos a esta amenaza (una clasificación del parque inmobiliario en diferentes tipologías constructivas, así como su vulnerabilidad). La vulnerabilidad de estas tipologías se describe por medio de funciones de daño: espectros de capacidad, que representan su comportamiento ante las fuerzas horizontales motivadas por los sismos, y curvas de fragilidad, que representan la probabilidad de que las estructuras sufran daños al alcanzar el máximo desplazamiento horizontal entre plantas debido a la mencionada fuerza horizontal. La metodología que se propone especifica determinadas pautas y criterios para estimar el movimiento, asignar la vulnerabilidad y evaluar el daño, cubriendo los tres estados del proceso. Por una parte, se consideran diferentes modelos de movimiento fuerte incluyendo el efecto local, y se identifican los que mejor ajustan a las observaciones de 2010. Por otra se clasifica el parque inmobiliario en diferentes tipologías constructivas, en base a la información extraída en una campaña de campo y utilizando además una base de datos aportada por el Ministerio de Obras Públicas de Haití. Ésta contiene información relevante de todos los edificios de la ciudad, resultando un total de 6 tipologías. Finalmente, para la estimación del daño se aplica el método capacidad-demanda implementado en el programa SELENA (Molina et al., 2010). En primer lugar, utilizado los datos de daño del terremoto de 2010, se ha calibrado el modelo propuesto de cálculo de riesgo sísmico: cuatro modelos de movimiento fuerte, tres modelos de tipo de suelo y un conjunto de funciones de daño. Finalmente, con el modelo calibrado, se ha simulado un escenario sísmico determinista correspondiente a un posible terremoto con epicentro próximo a Puerto Príncipe. Los resultados muestran que los daños estructurales serán considerables y podrán llevar a pérdidas económicas y humanas que causen un gran impacto en el país, lo que pone de manifiesto la alta vulnerabilidad estructural existente. Este resultado será facilitado a las autoridades locales, constituyendo una base sólida para toma de decisiones y adopción de políticas de prevención y mitigación del riesgo. Se recomienda dirigir esfuerzos hacia la reducción de la vulnerabilidad estructural - mediante refuerzo de edificios vulnerables y adopción de una normativa sismorresistente- y hacia el desarrollo de planes de emergencia. Abstract After the devastating 12 January 2010 earthquake that hit the city of Port-au-Prince, Haiti, strategies to minimize the high seismic risk are being developed by local authorities, NGOs, and national and international institutions. Two important tasks to reach this objective are, on the one hand, the evaluation of the seismic risk associated to possible future earthquakes in order to know the dimensions of the catastrophe; on the other hand, the design of preventive measures and emergency plans to minimize the consequences of such events. In this sense, this Master Thesis provides a detailed estimation of the damage that a possible future earthquake will cause in Port-au-Prince. A methodology to calculate the seismic risk is proposed, adapted to the study area conditions. This methodology has been calibrated using data from the 2010 earthquake. It has been conducted in the frame of the Sismo-Haiti cooperative project, supported by the Technical University of Madrid, which started ten months after the 2010 earthquake as an answer to an aid call of the Haitian government. The seismic risk calculation requires two inputs: the seismic hazard (expected ground motion due to a scenario earthquake given by magnitude and location) and the elements exposed to the hazard (classification of the building stock into building typologies, as well as their vulnerability). This vulnerability is described through the damage functions: capacity curves, which represent the structure performance against the horizontal forces caused by the seisms; and fragility curves, which represent the probability of damage as the structure reaches the maximum spectral displacement due to the horizontal force. The proposed methodology specifies certain guidelines and criteria to estimate the ground motion, assign the vulnerability, and evaluate the damage, covering the whole process. Firstly, different ground motion prediction equations including the local effect are considered, and the ones that have the best correlation with the observations of the 2010 earthquake, are identified. Secondly, the classification of building typologies is made by using the information collected during a field campaign, as well as a data base provided by the Ministry of Public Works of Haiti. This data base contains relevant information about all the buildings in the city, leading to a total of 6 different typologies. Finally, the damage is estimated using the capacity-spectrum method as implemented in the software SELENA (Molina et al., 2010). Data about the damage caused by the 2010 earthquake have been used to calibrate the proposed calculation model: different choices of ground motion relationships, soil models, and damage functions. Then, with the calibrated model, a deterministic scenario corresponding to an epicenter close to Port-au-Prince has been simulated. The results show high structural damage, and therefore, they point out the high structural vulnerability in the city. Besides, the economic and human losses associated to the damage would cause a great impact in the country. This result will be provided to the Haitian Government, constituting a scientific base for decision making and for the adoption of measures to prevent and mitigate the seismic risk. It is highly recommended to drive efforts towards the quality control of the new buildings -through reinforcement and construction according to a seismic code- and the development of emergency planning.

Enhancing Evacuation Plans with a Situation Awareness System Based on End-User Knowledge Provision.

Recent disasters have shown that having clearly defined preventive procedures and decisions is a critical component that minimizes evacuation hazards and ensures a rapid and successful evolution of evacuation plans. In this context, we present our Situation-Aware System for enhancing Evacuation Plans (SASEP) system, which allows creating end-user business rules that technically support the specific events, conditions and actions related to evacuation plans. An experimental validation was carried out where 32 people faced a simulated emergency situation, 16 of them using SASEP and the other 16 using a legacy system based on static signs. From the results obtained, we compare both techniques and discuss in which situations SASEP offers a better evacuation route option, confirming that it is highly valuable when there is a threat in the evacuation route. In addition, a study about user satisfaction using both systems is presented showing in which cases the systems are assessed as satisfactory, relevant and not frustrating.

Estimación del coste de almacenamiento de una solución de preservación de la privacidad en archivos BAM reales

A menudo los científicos secuencian el ADN de un gran número de personas con el objetivo de determinar qué genes se asocian con determinadas enfermedades. Esto permite meóon del genoma humano. El precio de un perfil genómico completo se ha posicionado por debajo de los 200 dólares y este servicio lo ofrecen muchas compañías, la mayor parte localizadas en EEUU. Como consecuencia, en unos pocos a~nos la mayoría de las personas procedentes de los países desarrollados tendrán los medios para tener su ADN secuenciado. Alrededor del 0.5% del ADN de cada persona (que corresponde a varios millones de nucleótidos) es diferente del genoma de referencia debido a variaciones genéticas. Así que el genoma contiene información altamente sensible y personal y representa la identidad biológica óon sobre el entorno o estilo de vida de uno (a menudo facilmente obtenible de las redes sociales), sería posible inferir el fenotipo del individuo. Multiples GWAS (Genome Wide Association Studies) realizados en los últimos a~nos muestran que la susceptibilidad de un paciente a tener una enfermedad en particular, como el Alzheimer, cáncer o esquizofrenia, puede ser predicha parcialmente a partir de conjuntos de sus SNP (Single Nucleotide Polimorphism). Estos resultados pueden ser usados para medicina genómica personalizada (facilitando los tratamientos preventivos y diagnósticos), tests de paternidad genéticos y tests de compatibilidad genética para averiguar a qué enfermedades pueden ser susceptibles los descendientes. Estos son algunos de los beneficios que podemos obtener usando la información genética, pero si esta información no es protegida puede ser usada para investigaciones criminales y por compañías aseguradoras. Este hecho podría llevar a discriminaci ón genética. Por lo que podemos concluir que la privacidad genómica es fundamental por el hecho de que contiene información sobre nuestra herencia étnica, nuestra predisposición a múltiples condiciones físicas y mentales, al igual que otras características fenotópicas, ancestros, hermanos y progenitores, pues los genomas de cualquier par de individuos relacionados son idénticos al 99.9%, contrastando con el 99.5% de dos personas aleatorias. La legislación actual no proporciona suficiente información técnica sobre como almacenar y procesar de forma segura los genomas digitalizados, por lo tanto, es necesaria una legislación mas restrictiva ---ABSTRACT---Scientists typically sequence DNA from large numbers of people in order to determine genes associated with particular diseases. This allows to improve the modern healthcare and to provide a better understanding of the human genome. The price of a complete genome profile has plummeted below $200 and this service is ofered by a number of companies, most of them located in the USA. Therefore, in a few years, most individuals in developed countries will have the means of having their genomes sequenced. Around 0.5% of each person's DNA (which corresponds to several millions of nucleotides) is diferent from the reference genome, owing to genetic variations. Thus, the genome contains highly personal and sensitive information, and it represents our ultimate biological identity. By combining genomic data with information about one's environment or lifestyle (often easily obtainable from social networks), could make it possible to infer the individual's phenotype. Multiple Genome Wide Association Studies (GWAS) performed in recent years have shown that a patient's susceptibility to particular diseases, such as Alzheimer's, cancer, or schizophrenia, can be partially predicted from sets of his SNPs. This results can be used for personalized genomic medicine (facilitating preventive treatment and diagnosis), genetic paternity tests, ancestry and genealogical testing, and genetic compatibility tests in order to have knowledge about which deseases would the descendant be susceptible to. These are some of the betefts we can obtain using genoma information, but if this information is not protected it can be used for criminal investigations and insurance purposes. Such issues could lead to genetic discrimination. So we can conclude that genomic privacy is fundamental due to the fact that genome contains information about our ethnic heritage, predisposition to numerous physical and mental health conditions, as well as other phenotypic traits, and ancestors, siblings, and progeny, since genomes of any two closely related individuals are 99.9% identical, in contrast with 99.5%, for two random people. The current legislation does not ofer suficient technical information about safe and secure ways of storing and processing digitized genomes, therefore, there is need for more restrictive legislation.
