Universidad Politécnica de Valencia. Escuela Técnica Superior de Ingeniería del Diseño Resumen de los autores El aprendizaje basado en proyectos es un método docente que puede facilitar la asimilación de nuevos conceptos y competencias por parte de los alumnos, ya que este método permite crear una atmosfera para la generación de ideas, la cooperación en el trabajo y la puesta en marcha de propuestas de ingeniería. Este tipo de aprendizaje también facilita el trabajo y el control de algunas de las llamadas competencias transversales, que determinan la capacidad del alumno en aspectos como la comprensión e integración, la innovación, la creatividad, el emprendimiento, la capacidad de diseñar un proyecto, el trabajo en grupo, la planificación, la gestión del tiempo, etc. Estas competencias son de carácter general pero la Universitat Politècnica de València (UPV) ha regulado su puesta en marcha en las titulaciones de grado y postgrado. En esta comunicación se presentan las características de cinco asignaturas de la materia de electrónica en diferentes titulaciones de grado que se imparten en la Escuela Técnica Superior de Ingeniería del Diseño (ETSID) de la UPV donde se aplica una docencia basada en el aprendizaje en proyectos. Para cada una de las asignaturas se especifican cuáles son sus características generales, la metodología docente empleada en relación a los proyectos realizados por los alumnos, la evaluación de los contenidos de las competencias transversales y los resultados obtenidos.

Spontaneous dissection of the renal artery is a rare phenomenon, and is more common amongst men. It is not a frequent cause of abdominal pain², which is why diagnosis is often late. The case under study is a 45 year old patient that presented sudden pain in the left renal fossa of 12 hours evolution, with no findings from the basic laboratory tests (lab testing, urinary sediment and ultrasound), an abdominal CAT was therefore carried out, which showed areas of renal infarction, as well as an emergency arteriogram, which gave findings of a possible Fibromuscular Dysplasia of the left intrarenal artery as the first diagnostic probability with a partially thrombosed focal dissection.

Adolescence is a crucial period to learn Emotional Regulation (ER) strategies to prevent future psychological problems. This work is aimed to test the efficacy of GameTeen System (GT-System), a serious game that teaches ER strategies to regulate joy (VAS scale) and perceived arousal (FAS scale) in a non-clinical sample of adolescents. We conducted a between-participants experiment in which participants (N = 63) played a joy induction game, and then an ER game using one of three types of devices (computer, smartphone, and RGB-D camera). Results revealed that GT-System was only effective in increase perceived arousal after the joy induction game and decrease after the ER game. Statistically significant differences were found between devices conditions after the joy induction game (more intense perceived arousal was reported by participants in RGB-D camera). This finding highlights that the type of device could be an important variable in the efficacy of serious game.

El objetivo de esta comunicación es proporcionar distintas estrategias para la introducción de actividades didácticas diseñadas bajo las premisas del Aprendizaje Basado en Videojuegos (ABV) de modo que se pueda hacer uso de la potencia pedagógica de los mismos en prácticamente cualquier circunstancia o entorno: (a) Utilización de videojuegos comerciales. (b) Utilización de juegos serios. (c) Docentes como diseñadores de juegos. (d) Alumnos como diseñadores de juegos. (e) Gamificación. De manera adicional, incluimos en cada estrategia propuesta, recomendaciones de distintos entornos de desarrollo y plataformas que, por su extendida utilización y madurez, se han mostrado´ como herramientas exitosas y consolidadas. Del mismo modo, se proponen diferentes líneas de diseño instruccional dentro de cada estrategia para inspirar y motivar a los docentes a utilizar el ABV en diferentes circunstancias y diversos entornos y etapas educativas. A partir de numerosas evidencias y recomendaciones, pretendemos crear una sencilla guía inicial para que cualquier docente, independientemente de su perfil, sea capaz de desarrollar una experiencia de ABV de manera confiada, sencilla y efectiva.

When applied to binary data, most classification algorithms behave well provided the dataset is balanced. However, when one single class includes the majority of cases, a good predictive performance for the minority class is not easy to achieve. We examine the strengths and weaknesses of three tree-based models when dealing with imbalanced data.We also explore sampling and cost sensitive methods as strategies for improving machine learning algorithms. An application to a large dataset of breath alcohol content tests performed in Catalonia (Spain) to detect drunk drivers is shown. The Random Forest method proved to be the model of choice if a high performance is required, while down- sampling strategies resulted in a significant reduction in computing time. When predicting alcohol impairment, the area of control (built-up or not), hour of day and drivers age were the most relevant variables for classification.

The relationship between the use of cannabis and the decision-making processes was explored. A computerized version of the Iowa Gambling Task (Cards Software) in its normal and reverse version was used, and the Prospect Valence Learning (PVL) model, which characterize the process of decision-making based on the parameters: Recency, Consistency, Loss aversion and Utility shape, was applied. Seventy-three cannabis consumers and a control group with 73 nonconsumers participated in the study. In the normal mode, subjects in the control group scored higher than cannabis consumers. Both groups showed consistent responses and aversion to loss. Nonconsumers showed greater influence of the gain-loss frequency, while consumers were more influenced by the magnitude of the gain-loss. The influence of immediate choices was higher among consumers who showed a quick oblivion while in the control group this process was more gradual. In the reverse mode, task performance was better among control group participants. Both groups showed consistency, loss aversion, more influenced by the magnitude of the gain-loss, and low influence of immediate elections. The results show the relationship between drug use and the decision-making processes, being consistent with the results obtained in other studies where consumers had worse results than control group. Moreover, the PVL parameters allow to adequately characterize decision-making. This confirms the relationship between drug use and decision-making by either the vulnerability prior to consumption or the neurotoxicity of drugs.

Self-monitoring techniques, such as the use of dietary registers, are considered to be central to cognitive-behavioral treatment of Eating Disorders (ED). This information allows the clinician to identify the triggers of the behaviors associated to ED as purges and/or binges, and the associated thoughts and emotions, helping to carry out a more accurate assessment. Traditionally these registers are made with paper and pencil mode, where the patient has to register every eating and the emotions/thoughts associated; but this system has some problems, as low portability, low adherence or methodological difficulties. The use of PDA for self-registers can help to solve these problems. The aim of this study is to study the levels of acceptability and satisfaction with PDAs self-register system specifically designed for assessment and treatment of ED. Samples of 30 subjects diagnosed with ED are receiving a PDA with software specifically designed for recording type and amount of food, emotions before and after eating and other behaviors. The participants are completing self-register daily during a week, and afterwards answer an acceptance and satisfaction questionnaire. This work is in progress at the moment. It is expected that the PDA system will show high levels of acceptance and satisfaction.

The emergence of new shared media, such as the Internet and virtual reality are changing the ways in which people relate, communicate, and live. Health care, and in particular clinical psychology, is one of the areas that could be most dramatically reshaped by these new technologies. To exploit and understand this potential is the overall goal of the "Telemedicine and Portable Virtual Environment in Clinical Psychology"--VEPSY UPDATED--an European Community funded research project (IST-2000-25323, http://www.vepsy.com) whose specific goal is the development of different PC based virtual reality modules to be used in clinical assessment and treatment. In particular the developed modules have been using to address the following pathologies: anxiety disorders; male impotence and premature ejaculation; obesity, bulimia and binge-eating disorders. The chapter details the general technical and clinical characteristics of the developed modules.
