Conceptual modeling has always been one of the main issues in information systems engineering as it aims to describe the general knowledge of the system at an abstract level that facilitates user understanding and software development. This collection of selected papers provides a comprehensive and extremely readable overview of what conceptual modeling is and perspectives on making it more and more relevant in our society. It covers topics like modeling the human genome, blockchain technology, model-driven software development, data integration, and wiki-like repositories and demonstrates the general applicability of conceptual modeling to various problems in diverse domains. Overall, this book is a source of inspiration for everybody in academia working on the vision of creating a strong, fruitful and creative community of conceptual modelers. With this book the editors and authors want to honor Prof. Antoni Olive for his enormous and ongoing contributions to the conceptual modeling discipline. It was presented to him on the occasion of his keynote at ER 2017 in Valencia, a conference that he has contributed to and supported for over 20 years. Thank you very much to Antoni for so many years of cooperation and friendship.

La prevalencia de la obesidad y el sobrepeso infantojuvenil aumenta con el paso del tiempo. Las repercusiones fisicas, psiquicas, sociales y emocionales producidas por estas patologias dificultan el desarrollo integral del estudiante. El exceso de peso esta directamente relacionado con la dieta, el ejercicio fisico y el sedentarismo. Este proyecto es una propuesta de intervencion hacia el alumnado de educacion secundaria obligatoria para disminuir la incidencia del sobrepeso y obesidad. Se estructura en tres unidades didacticas en los que se muestra la importancia de la condicion fisica y los habitos saludables en la salud.
