    A significant amount of effort has been put in developing tools to interpret Ground Penetrating Radar signals obtained during surveys. Currently, skilled and experienced users do most of GPR image interpretation. They use experience in deciphering what the GPR signals represent. A successful survey will not only depend on the choice of antenna used, but also on the operating parameters used for the survey. This study aims at providing a library of GPR images taken from known targets with known parameters. The targets include a set of different sizes of steel rebars. The library of GPR images is developed using known targets set in a sand box. Sand has proven to have the same properties as Portland cement concrete in response to GPR signals. The sand box simulates a concrete slab; it is used for ease of placement of different targets with various configurations. The developed library of GPR images will be used for training of GPR users and comparison studies of GPR operating parameters. In the future these images can be used for a pattern recognition algorithm development, or any other theoretical study pertaining to GPR image interpretation

    Intentamos en este trabajo contrastar la relación existente entre calidad de vida y deporte, partiendo de la revisión de los trabajos que recientemente han investigado en esta dirección. Así, comparamos las conclusiones que los diferentes estudios indica entre la mejora de la calidad de vida a partir de la realización de una práctica deportiva sistemática, y los componentes motivacionales que están en el origen de las personas que se inician en esta práctica. Precisamos que la no adaptación de ambos intereses (programas de actividad física y deporte con motivaciones para su realización puede ocasionar diferentes alteraciones, entre otras estrés). Se realiza a continuación una descripción de los diferentes.In this work, we try to show the relationship between life quality and sport, beginning from the works that have recently researched in this direction. In this way, we compare the conclusions that the different studies suggest between the improvement of the life quality beginning from the realization of a sistematic sport practice and the motivational components which are in the origin of people who initiate themselves into this practice. Likewise, we determine that when both interests (sport and physic activity programs and motivations for its realization) don't meet, different alterations can appear, stress for instance. Later, we realize a description of different predictors that can be in the origin of stress, as well as more adequate strategies for its intervention and prevention
