El principal objetivo de este trabajo fue diseñar y ensayar un procedimiento sistemático de medición de la carga de trabajo, orientado a detectar y corregir valores anómalos de esta. La carga de trabajo es uno de los aspectos del contexto académico que más afectan al comportamiento académico del estudiante universitario. Un exceso o una inadecuada distribución de la carga en una o varias asignaturas puede repercutir en las restantes, dificultar la organización de las actividades docentes y de evaluación y potenciar que los estudiantes adoptan enfoques superficiales de aprendizaje. Hemos realizado una prueba piloto para ensayar y comparar dos procedimientos distintos: un cuestionario semanal que evalúa la carga real en horas de cada actividad docente y una encuesta puntual que cuantifica la carga percibida por el estudiante en cada asignatura y en la que pueden incluirse también comentarios sobre la carga de trabajo. En ambos casos la información solicitada es únicamente sobre la carga no presencial. El análisis y la comparación de los datos obtenidos de la prueba piloto ha permitido contrastar y matizar nuestra idea inicial, además de confirmar las conclusiones de algunos estudios anteriores. Tras considerar la viabilidad de ambos procedimientos, nuestra Universidad decidió aplicar la encuesta puntual de carga percibida. En este trabajo describimos la prueba piloto realizada y presentamos los resultados de las primeras campañas de medición sistemática realizadas.

The dissemination of reality-based models allows a more exhaustive knowledge of the object of study and enables a better access through real-time applications running on common devices connected to the web. In addition, difficult-to-appreciate works of art can become object of specifically designed serious educational games through the possibilities allowed by game engines. The definition of a pipeline that leads from a reliable acquisition of shape, color and BRDF features to a motivating and satisfying interactive experience is the focus of this paper. It will be analyzed, in an interdisciplinary perspective, and will undergo a series of steps aimed at preserving the features of the work of art without compromising its realistic and fluid visualization, as well as the characteristics at the base of the stylistic and artistic quality.

The accurate graphic survey of an archaeological site is fundamental for its analysis and research. Furthermore, if this site is to be covered by a building and will not be accessible or visible, its documentation is essential, not only to continue with the research, but also to disseminate and enhance the discoveries. An example of this is the "Hoya de los Molinos" archaeological site in Caravaca de la Cruz (Region of Murcia, Spain). This is where the first mark of the wheel of a Roman vertical watermill in the Iberian Peninsula has been found. This fact is crucial because remains of Roman vertical-wheeled watermills have been found across the Mediterranean but not in the Iberian Peninsula. Moreover, the fact that this watermill still has all its structural elements makes this archaeological site in Caravaca de la Cruz very interesting. Due to these facts, it is essential to disseminate this discovery, so that it can be recognized and considered as archaeological and cultural heritage. To that end, the researchers have carried out a three-dimensional (3D) reconstruction of the most characteristic elements, such as the vertical wheel, the gears that allowed grinding the grain, and the building protecting them. A virtual recreation was carried out, based on the historical and building research, which is displayed in an explanatory video. Furthermore, two reproductions were created: one made to scale of the archaeological site with a 3D printer and another one of the hypothetical structure of the Roman watermill. To achieve this result, historians, archaeologists and engineers have collaborated, thus enabling not only its adequate dissemination, but also its accurate documentation, in an inclusive manner. Thanks to all the work that this paper describes, the Roman watermill found in Caravaca de la Cruz can be known, studied and assessed.Highlights:The first Roman watermill in the Iberian Peninsula has been found with all its structural elements, from the imprints left in the stone by the wheel.Virtual reconstruction of the first vertical wheel watermill discovered in Hispania has been made.An animated video of the hydraulic watermill gears performance has been created for documentation and dissemination.

The city of Cartagena and its immediate surroundings have experienced significant topographical changes throughout its history. Originally built on five hills which border south and west with the Mediterranean Sea, the city has expanded to the north over the last five decades, occupying a lacustrine system which has now dried up due to the diversion of riverbeds which, from time to time, used to flood the place. These changes have been documented and studied from the lithology present in over 400 geotechnical drillings carried out in the urban renewal of the city for the last two decades. In addition, another 20 new continuous drillings have been conducted within the Project “Surveying and planning a privileged Mediterranean city, Arqueotopos I and II” which is still ongoing. The information obtained is completed with the study of all existing historical maps on it. Digital Terrain Models (DTMs) have been generated with this drilling data, then several lithological layers have been selected for its interest: anthropic fill, mud and underlying bedrock. The thickness of each of the layers has been studied in different areas and viewed through various longitudinal profiles that have been plotted. Finally, a three-dimensional (3D) virtual reconstruction has been undertaken to see graphically the documented changes that have occurred in each of these layers, to serve both research and divulgation knowledge.

El programa DOCENTIA de ANECA se de­sarrolló como base para los modelos me­diante los cuales las universidades espa­ñolas evalúan la docencia del profesorado, una necesidad ligada a los requerimientos de transparencia y de mejora continua que están en la esencia del EEES. Entre los in­dicadores habituales en estos modelos destacan las encuestas de satisfacción de los estudiantes, cuya validez es objeto de debate desde el origen de su utilización. Una de las opiniones críticas más extendi­das sostiene que las encuestas no son una buena referencia, porque contienen ses­gos inasumibles. Con el objetivo de com­probar si existen realmente esos sesgos, se ha realizado un estudio estadístico a partir de los datos de indicadores de calidad en la Universidad Politécnica de Cartagena. Se ha empleado la regresión lineal múlti­ple, mediante el procedimiento conocido como regresión hacia atrás, para identifi­car las variables que pudieran influir en las valoraciones que hacen los estudiantes y cuantificar su efecto. El principal resultado del estudio es que las variables analizadas, que suelen citarse como causas de sesgo, muestran una influencia poco o nada signi­ficativa sobre los resultados de las encues­tas. Por otra parte, es importante subrayar que hay aspectos de la actividad docente que solamente pueden evaluarse a partir de la observación sistemática que hacen los estudiantes. Por todo ello considera­mos que las encuestas de satisfacción son un indicador indispensable, y es funda­mental que el peso que se les asigna en el modelo de evaluación docente refleje su importancia.

The Negro Tower or Arráez Tower, in El Algar (Cartagena, Spain), dates from 1585. This tower was part of an extensive network of watch and defense towers built along the coastline of Murcia between the sixteenth and seventeenth centuries. It is an inland rural tower, in visual contact with the coastal towers. Its objective was to receive and transfer warnings from onshore towers to protect the population, especially farmers. The tower is protected as a monument but is currently in a dilapidated state of conservation. Therefore, this building has been chosen as the object of an integral study, which can serve as a reliable basis for its correct conservation and restoration. Through historical analysis, light has been shed upon the evolution of the Tower from the social, cultural, and architectural points of view. The graphic documentation has been made using digital photogrammetry and a 3D laser scanner, compatible with classical topography. Based on all this information, an integral project of consolidation and volumetric recomposition of the tower has been proposed. As a result of this research, we intend to contribute to the conservation and recovery of the heritage value of the Tower, as well as the integration of the historic monument in its natural environment.
