Survey on integration of Applied Geology and Geomorphology in Civil Engineering curricula in the framework of the European Higher Education Area (EHEA) by using practical trips

The engineer must have sufficient theoretical knowledge to be applied to solve specific problems, with the necessary capacity to simplify these approaches, and taking into account factors such as speed, simplicity, quality and economy. In Geology, its ultimate goal is the exploration of the history of the geological events through observation, deduction, reasoning and, in exceptional cases by the direct underground exploration or experimentation. Experimentation is very limited in Geology. Reproduction laboratory of certain phenomena or geological processes is difficult because both time and space become a large scale. For this reason, some Earth Sciences are in a nearly descriptive stage whereas others closest to the experimental, Geophysics and Geochemistry, have assimilated progress experienced by the physics and chemistry. Thus, Anglo-Saxon countries clearly separate Engineering Geology from Geological Engineering, i.e. Applied Geology to the Geological Engineering concepts. Although there is a big professional overlap, the first one corresponds to scientific approach, while the last one corresponds to a technological one. Applied Geology to Engineering could be defined as the Science and Applied Geology to the design, construction and performance of engineering infrastructures in and field geology discipline. There has been much discussion on the primacy of theory over practice. Today prevails the exaggeration of practice, but you get good workers and routine and mediocre teachers. This idea forgets too that teaching problem is a problem of right balance. The approach of the action lines on the European Higher Education Area (EHEA) framework provides for such balance. Applied Geology subject represents the first real contact with the physical environment with the practice profession and works. Besides, the situation of the topic in the first trace of Study Plans for many students implies the link to other subjects and topics of the career (tunnels, dams, groundwater, roads, etc). This work analyses in depth the justification of such practical trips. It shows the criteria and methods of planning and the result which manifests itself in pupils. Once practical trips experience developed, the objective work tries to know about results and changes on student’s motivation in learning perspective. This is done regardless of the outcome of their knowledge achievements assessed properly and they are not subject to such work. For this objective, it has been designed a survey about their motivation before and after trip. Survey was made by the Unidad Docente de Geología Aplicada of the Departamento de Ingeniería y Morfología del Terreno (Escuela Técnica Superior de Ingenieros de Caminos, Canales y Puertos, Universidad Politécnica de Madrid). It was completely anonymous. Its objective was to collect the opinion of the student as a key agent of learning and teaching of the subject. All the work takes place under new teaching/learning criteria approach at the European framework in Higher Education. The results are exceptionally good with 90% of student’s participation and with very high scores in a number of questions as the itineraries, teachers and visited places (range of 4.5 to 4.2 in a 5 points scale). The majority of students are very satisfied (average of 4.5 in a 5 points scale).

New methodology on Applied Geology and Geology for Engineers education by using practical trip

There has been much discussion on the primacy of theory over practice. Today prevails the exaggeration of practice. This idea forgets too that teaching problem is a problem of right balance. The approach of the action lines on the European Higher Education Area (EHEA) framework provides for such balance. Applied Geology subject represents the first real contact with the physical environment with the practice profession and works. Besides, the situation of the topic in the first trace of Study Plans for many students implies the link to other subjects and topics of the career. This work analyses in depth the justification of such practical trips only on Applied Geology. This methodology could be usual in Study Plans of pure sciences career, Geology or Biology, but not in Civil Engineering like teaching method. It shows the criteria and methods of planning and the result which manifests itself in pupils. Therefore, work shows a methodology taking in account the engineering perspective, the practical point of view and the learning process inside students and their evaluation and, hence, their marks.

Estudio de procesos y herramientas aplicables a la generalización vectorial de entidades lineales.

Se presenta un estudio de algoritmos que ofrecen resultados óptimos en cuanto a lo que a la generalización vectorial de entidades lineales se refiere. Este estudio se encuentra dentro del marco del proyecto CENIT España Virtual para la investigación de nuevos algoritmos de procesado cartográfico. La generalización constituye uno de los procesos cartográficos más complejos, cobrando su mayor importancia a la hora de confeccionar mapas derivados a partir de otros a mayores escalas. La necesidad de una generalización se hace patente ante la imposibilidad de representar la realidad en su totalidad, teniendo ésta que ser limitada o reducida para la posterior elaboración del mapa, manteniendo, eso sí, las características esenciales del espacio geográfico cartografiado. La finalidad, por tanto, es obtener una imagen simplificada pero representativa de la realidad. Debido a que casi el ochenta por ciento de la cartografía vectorial está compuesta por elementos lineales, la investigación se centra en aquellos algoritmos capaces de procesar y actuar sobre éstos, demostrando además que su aplicación puede extenderse al tratamiento de elementos superficiales ya que son tratados a partir de la línea cerrada que los define. El estudio, además, profundiza en los procesos englobados dentro de la exageración lineal que pretenden destacar o enfatizar aquellos rasgos de entidades lineales sin los que la representatividad de nuestro mapa se vería mermada. Estas herramientas, acompañadas de otras más conocidas como la simplificación y el suavizado de líneas, pueden ofrecer resultados satisfactorios dentro de un proceso de generalización. Abstract: A study of algorithms that provide optimal results in vector generalization is presented. This study is within the CENIT project framework of the España Virtual for research of new cartographic processing algorithms. The generalization is one of the more complex mapping processes, taking its greatest importance when preparing maps derived from other at larger scales. The need for generalization is evident given the impossibility of representing whole real world, taking it to be limited or reduced for the subsequent preparation of the map, keeping main features of the geographical space. Therefore, the goal is to obtain a simplified but representative image of the reality. Due to nearly eighty percent of the mapping vector is composed of linear elements, the research focuses on those algorithms that can process them, proving that its application can also be extended to the treatment of surface elements as they are treated from the closed line that defines them. Moreover, the study focussed into the processes involved within the linear exaggeration intended to highlight or emphasize those features of linear entities that increase the representativeness of our map. These tools, together with others known as the simplification and smoothing of lines, can provide satisfactory results in a process of generalization.

Arquitectura y construcción, paisaje y territorio : los refugios de la Cuenca Alta del río Tajo

La Tesis estudia un tipo de refugio ganadero de la Cuenca Alta del río Tajo, conocidos como chozones. Singular arquitectura ligada a la ganadería extensiva ovina que servía de abrigo al ganado durante la noche invernal y umbráculo en estío. Construcciones de muros bajos de mampuesto colocados a hueso de planta circular o rectangular, levantadas alrededor de una estructura leñosa o un árbol en posición de vida que soportan una cubierta de ramas de la poda de la sabina. Son cientos diseminados por toda la región, si bien concentrados en la Sesma del sabinar, una de las cuatro divisiones históricas del Señorío de Molina. La decadencia de la ganadería en la comarca, sumada a otras causas de sociales y económicas, ha llevado a que estén cada vez en peor estado de conservación; con todo lo que ello supone de pérdida de una memoria histórica inseparable del paisaje del que son parte. Mi primera aproximación a estos refugios fue una oferta que aceptó el equipo de dirección del Parque Natural del Alto Tajo para catalogar los que se encontraban en su área de protección, un paisaje de Alto Valor Natural donde la ganadería ha sido el sustento tradicional. Tras terminar el inventario se produjo el gran incendio en Riba de Saélices (2005). Además de calcinar a 11 retenes voluntarios, quemó parte de las chozones inventariados. Tomé entonces consciencia de la fragilidad de este patrimonio popular y del valor que cobraba el trabajo realizado, pues en muchos casos era el único testimonio que había de los chozones desaparecidos. De ahí nació esta investigación. Al comienzo el enfoque analítico fue eminentemente disciplinar, como recoge la primera parte del título de la tesis: arquitectura y construcción. Pronto comprendí que este enfoque no era suficiente para entender las preguntas dejadas abierta por el análisis espacial, tales como su origen, razón de ser, función social, etc. Profundizando en estos temas la investigación fue haciéndose más amplia y transversal, hasta llegar a lo indicado en la segunda parte del título: paisaje y territorio. En síntesis, la tesis pasó del análisis de un objeto en sí a su entendimiento como parte de una sociedad y un paisaje del que es indisoluble. Para lograr estos objetivos transversales, los refugios ganaderos se estudiaron considerando desde sus aspectos geográficos e históricos a los propios de la arquitectura y del sistema ganadero que acoge. A cada enfoque se dedica un capítulo de la Tesis, lo que nos obligó a utilizar distintas metodologías de análisis: de un amplio trabajo de campo para catalogar y levantar los casi un centenar de chozones inventariados a la búsqueda de información documental en archivos históricos. Por el carácter del estudio fue también fundamental la revisión del material etnográfico de la zona, así como las entrevistas con vecinos y los pocos pastores que quedaban en los municipios estudiados. Los resultados de la Tesis muestran que los refugios ganaderos son construcciones con una serie de valores de distinto tipo. Entre ellos destacaría: (a) ambientales, porque son arquitecturas integradas en el medio ambiente, con empleo de materiales del territorio y adaptación a sus condiciones físicas; (b) históricos, porque son testimonio de un patrimonio arquitectónico que al menos desde la Edad Media se mantiene sin apenas modificaciones; (c) etnográficos, porque son un elemento arquitectónico con usos estrechamente ligados a la cultura tradicional, ganadera y rural de la cuenca del Alto Tajo. Tan clara es la relación entre estos tres aspectos que no es exagerado afirmar que desde el comienzo hasta su final, pasando por las distintas actividades cotidianas, la vida de los habitantes de la comarca giraba en torno al patrimonio vernáculo estudiado. Por ello, entendemos que todos estos elementos son lo suficientemente relevantes como para intentar evitar su destrucción, fomentar una reutilización que contribuya a un desarrollo sostenible de este singular paisaje etnológico. ABSTRACT My first approach to these refugees was commissioned by the management of the Alto Tajo Natural Park to catalog those who were in their protection area, a landscape of high natural value where livestock has been the traditional livelihood. After completing the inventory came the great fire in Riba de Saelices (2005). Besides calcine 11 firefighters, burned many of these popular architectures. I took then awareness of the fragility of this vernacular heritage and the value of the work charged, since in many cases it was the only witness who had disappeared from the shelters. At that time, this research was born. At the begging our study was eminently from the point of view of our discipline, as it picks up the first part of the title of the Thesis: architecture and construction. Soon I realized that this approach was not sufficient to understand the questions left open by the spatial analysis, such as its origin, purpose, social function, etc. By studying topics, my research become to be more comprehensive and transversal, up to coming to the indicated in the second part of the title: landscape and territory. In synthesis, the Thesis went on from the analysis of an object in itself to its understanding like part of a society and a landscape of which it is indissoluble. To achieve these cross-cutting objectives, livestock shelters were studied considering from its geographic and historic aspects to this relating to his architecture own the livestock system to which they belong. To each approach we devoted a chapter of the Thesis, which forced us to use different methodologies of analysis: an extensive field work in cataloguing and lift the nearly a hundred chozones inventoried to the search of documentary information in historical archives. By the nature of the study, the review of the ethnographic material in the area was also essential, as well as interviews with neighbors and the few remaining shepherds in the municipalities studied. The results of our Thesis show that livestock shelters are constructions with a series of values of different types. Among them I would highlight three: (a) environmental, because they are architectures integrated in the territory, with the use of materials of the location and adapted to their physical conditions; (b) historical, because they are testimony of an architectural heritage that at least since the Middle Ages remains with little modifications; (c) ethnographic, because they are architectural elements closely linked to livestock, rural and traditional culture of the Alto Tajo basin. So clear is the relationship between these three aspects, that is not an exaggeration to say that from the beginning until the end, passing through the various daily activities, the life of the inhabitants of the region was in completed connection with the studied vernacular heritage. For it, we understand that all these elements are relevant enough to try to prevent their destruction and promote a recycling that contributes to a sustainable development of this unique ethnological landscape.
