Testo completoInternet is the main scientific and health information source in the world, becoming one of the most important means for finding and publishing information. A characteristic of Internet is the ability to publish information on the net, either reliable or not, which means that its quality is questionable. The main objective of the present research is based on knowing the quality of the health web pages through the use of several questionnaires attending to different criteria. It is a transveral descriptive study. Target or object population were the main health information web pages, including Health Institutional webs.The accesibility degree of the several web evaluated was very low. Concretely, only 7.7% of web sites complies with Priority 1, Priority 2 was completed for a web site and no site met the Priority 3. No web page evaluated reached the maximum quality socre on every test applied: test for Accreditation of Health Agency of Andalusia, the HONcode and Bermudez et al. test. Quality of our evaluated web pages was not as expected, because it was very much lower. Also applies to regional health services because they do not stand out from the rest of the other health websites for their quality.We believe that it should intervene through a consensus of basic standards for health web sites and through the training of the user.

El objetivo de este estudio es evaluar la competencia informacional en el uso de Internet como fuente de información académica, de estudiantes de enfermería, en la Universitat Rovira i Virgili. Tarragona-España. Se utilizó una metodología mixta, que combina los cuestionarios y la captura en vídeo del proceso de búsqueda de los estudiantes. Los resultados evidencian una formación universitaria escasa y un bajo nivel de implicación del profesorado, frente a un alto uso de la Red como medio de acceso a información académica por parte de los estudiantes y elevada autopercepción sobre su habilidad para utilizar este medio, a pesar de demostrar pobres estrategias de búsqueda y selección de información y la manifestación de importantes problemas relacionados con estos procesos.
Nursing students from Campus Terres de l'Ebre informational competence to search and select academic information through Internet.
ABSTRACT:
Access to new technologies is not enough to ensure the acquisition of a good informational competence. Are we providing our students with a proper training to help them handle all the information they encounter with? The present study attempts to answer empirically to some of these questions and to evaluate the informational competence regarding the use of Internet as a source of academic information for nursing students at the Universitat Rovira i Virgili. Tarragona, Spain. To carry out this study we made use of a mixed methodology, combining questionnaires and video captures of the search process of students. The results show that there is little training during college education on this subject and a low level of involvement by teachers. This fact contrasts with a high use of the Internet on the student's part as a means of access to academic information and a high self-perception on the student's part regarding their skills and abilities to search. Evidences showed that despite their own beliefs students still demonstrate poor search strategies as well as scarce abilities to search and select information since and that there appeared important issues related to these processes.

Testo completoEn este trabajo de tesis se presenta y valida un modelo de interoperabilidad entre diferentes esquemas de metadatos en el plano semántico, adecuado para entornos de búsqueda de material, cuya principal aportación es que ofrece dicha interoperabilidad de forma transparente. Ni los proveedores de contenidos, que son los que ofrecen los metadatos, ni los usuarios, que son los que los consultan, tienen que ser conscientes de su existencia, permitiendo así que todos los actores presentes en el sistema sigan usando su propio esquema de metadatos. Para ello, el modelo requiere de la presencia de un agente externo que lo implemente.
Fer servir metadades per a referenciar, etiquetar i descriure recursos és cada cop més usual. Això permet establir millors mecanismes per a descobrir i localitzar material publicat en repositoris públics accessibles per la xarxa. S'estan duent a terme diverses iniciatives per a establir estàndards per a esquemas de metadades, però cada un es centra en els seus propis requeriments a l'hora de definir els atributs, el seu significat, els possibles valors que poden tenir, i la relació entre ells. Des del punt de vista de l'usuari que pretén buscar recursos a diferents entorns, això esdevé un problema real, perquè li obliga a disposar de les eines apropiades per a cada cas, o ser conscient de les diferències que existeixen entre els diferents entorns.
En aquest treball de tesi es presenta i valida un model d'interoperabilitat entre diferents esquemes de metadades en el pla semàntic, adequat per a entorns de cerca de material, la principal aportació del qual és que ofereix aquesta interoperabilitat de forma transparent. Ni els proveïdors de continguts, que són els que ofereixen les metadades, ni els usuaris, que són els que les consulten, han de ser conscients de la seva existència, permetent així que tots els actors presents al sistema segueixin emprant el seu propi esquema de metadades. Per a fer-ho, el model requereix la presència d'un agent extern que ho implementi.
Using metadata for referencing, tagging and describing resources is becoming more and more usual. This allows better ways of searching and discovering material published in public repositories, accessible through the net. Several initiatives are being carried out for establishing standards for metadata schemes, but each on focuses on their own requirements when defining the attributes, their meaning, the possible values they can have and the relation among them. From the point of view of the user who wants to search for resources in different environments, this is a real problem, because he is supposed to have proper tools for each situation, or he must know about the differences among them.
In this thesis an interoperability model at a semantic level is presented and validated. It is suitable for the search process, and its main contribution is that the interoperability is achieved in a transparent way. Neither the providers, who offer the metadata, nor the users, who look them up, have to be aware of the differences among them. Thus, all the actors in the environment can keep on using their own scheme. The model also specifies the existence of an agent to implement it.

Testo completoDas NP-vollständige Problem k-SAT ist von zentraler Bedeutung in der theoretischen Informatik. In der Dissertation werden zufällige 4-SAT-Formeln mit > n^2 vielen Klauseln studiert. Diese Formeln sind mit hoher Wahrscheinlichkeit unerfüllbar. Hier wird erstmalig die Existenz eines Algorithmus gezeigt, der diese Unerfüllbarkeit effizient verifiziert. Hierfür wird die geringe Diskrepanz von Hypergrpahen und Multigraphen betrachtet. Der Schlüssel zu diesem Algorithmus liegt in der Kombination von spektralen Techniken mit Approximationsalgorithmen der klassischen kombinatorischen Optimierung. Der vorgestellte Algorithmus kann auf den effizienten Nachweis der Unerfüllbarkeit von Not-All-Equal-4-SAT-Formeln und die Nicht-2-Färbbarkeit von 4-uniformen Hypergraphen erweitert werden. Es wird ebenfalls eine Erweiterung der Hajos-Konstruktion nicht k-färbbarer Graphen auf nicht k-färbbare uniforme Hypergraphen angegeben

Testo completoThe objetive of the thesis is the actual calculation of the geometric monodromy and the fundamental group of families of related compact Riemann surfaces (complex algebraic curves) of genus 4. This study extends to other developed so far within the framework of algebraic geometry, differential and symplectic topology, studying this geometric monodromy and fundamental group for families of Riemann surfaces of genus 2, using the elliptical structure / hyperelliptic of such families. The jump from genre 2 to genre 4 is performed to take advantage of the trigonal structure (triple coating of the Riemann sphere) with the curves in genus 4. Such a generic curve has two trigonal structures in a generic family can make a base change 2:1 to get hit trigonal structures coating the fibers and obtain a family of trigonal coverings of the Riemann sphere. The coating generic trigonal curves of genus 4 has 12 simple branch points. This means, in a family of trigonal coverings is a divisor of relative degree 12 in the family of Riemann spheres coated, called branching divisor, such that the braid monodromy of this divisor determines the geometric monodromy on the fundamental group of family. The main theoretical result of this report is to construct a universal family of trigonal curves of genus 4, under the scheme trigonal Hurwitz coatings, but smaller scale, geometric monodromy calculable, and maintains a topological property of universality: all family of coatings gender trigonal 4 is obtained by pullback of an application to the base of this universal family, the more distortion. Complete the main theoretical result calculating the geometric monodromy and the fundamental group of this family. This calculation is made following the braid monodromy of the branch divisor of the family, and raising the monodromy of the Riemann spheres of their triple decks. The calculation of the monodromy on the fundamental group of the family has not been completed from the logical point of view, due to a conjecture about the stabilizer of a braid group action in the Hurwitz scheme covers triples. However, the calculations remain valid whatever the answer should be true implies that the calculation is all the monodromy of the universal family and it would mean we must add some monodromy calculations similar to those made here. The theoretical results of the thesis is completed with computer work for geometric monodromy effective calculations in the fundamental group in families of curves of genus 4. First, we developed a library of functions for the program Singular which are the structure of trigonal curves of genus 4 from its canonical equation and with the help of an auxiliary calculation Pari-GP, determine the relative branching divisor of a family of canonical curves of genus 4 (not hyperelliptic). The thesis applies this library to the trigonal structure calculation and branching divisors in families of curves of genus 4, both academic and family examples of geometric interest: - The family of curves of genus 4 which describes a Lefschetz brush on the surface K3 genus 4 (whose geometric monodromy is needed to prove Paul Seidel version of the conjecture of the 'Mirror Symmetry') - A family of curves of genus 4 curve deformation Bring (the only curve of genus 4 having symmetry group of order 5). Second, develop a library of functions for the MATLAB program to compute the braid monodromy of a divisor in C ^ 2. This calculation starts on the integration of a system of ordinary differential equations with complex values, which follows the evolution of the branches of the splitter, for which we have developed a numerical integrator by combining a variable step Runge-Kutta method with the equation using the first integral divisor of solutions for pitch control. This system of equations is integrated on a system of generators of the fundamental group of the base obtained from a Voronoi cell decomposition associated with the values of branching of the family, and finally identifies the braid monodromy from the analysis of the position of the branches of the divider along the paths chosen in the base. This library works well for divisors up to 6-8 degrees in the plane. The thesis is illustrated by application to academic examples, complete with representation and identification of the braid monodromy in these examples

Testo completoEl resumen automático probablemente sea crucial en un momento en que la gran cantidad de documentos generados diariamente hace que recuperar, tratar y asimilar la información que contienen se haya convertido en una ardua y a su vez decisiva tarea. A pesar de ello, no podemos esperar que los resúmenes producidos de forma automática vayan a ser capaces de sustituir a los humanos. El proceso de resumen automático no sólo depende de las características propias de los documentos a ser resumidos, sino que es fuertemente dependiente de las necesidades específicas de los usuarios. Por ello, el diseño de un sistema de información para resumen conlleva tener en cuenta varios aspectos. En función de las características de los documentos de entrada y de los resultados deseados es posible aplicar distintas técnicas. Por esta razón surge la necesidad de diseñar una arquitectura flexible que permita la implementación de múltiples tareas de resumen. Este es el objetivo final de la tesis que presento dividido en tres subtemas de investigación. En primer lugar, estudiar el proceso de adaptabilidad de sistemas a diferentes tareas de resumen, como son procesar documentos producidos en diferentes lenguas, dominios y medios (sonido y texto), con la voluntad de diseñar una arquitectura genérica que permita la fácil incorporación de nuevas tareas a través de reutilizar herramientas existentes. En segundo lugar, desarrollar prototipos para distintas tareas, teniendo en cuenta aspectos relacionados con la lengua, el dominio y el medio del documento o conjunto de documentos que requieren ser resumidos, así como aspectos relacionados con el contenido final del resumen: genérico, novedad o resumen que de respuesta a una necesidad especifica. En tercer lugar, crear un marco de evaluación que permita analizar la competencia intrínseca de distintos prototipos al resumir noticias escritas y presentaciones científicas orales.

Testo completoIn diseases with a genetic component, examination of the phenotype can aid understanding the underlying genetics. Technologies to generate high-throughput phenotypes, such as RNA interference (RNAi), have been developed to decipher functions for genes. This large-scale characterization of genes strongly increases phenotypic information. It is a challenge to interpret results of such functional screens, especially with heterogeneous data sets. Thus, there have been only few efforts to make use of phenotype data beyond the single genotype-phenotype relationship. Here, methods are presented for knowledge discovery in phenotypes across species and screening methods. The available databases and various approaches to analyzing their content are reviewed, including a discussion of hurdles to be overcome, e.g. lack of data integration, inadequate ontologies and shortage of analytical tools. PhenomicDB 2 is an approach to integrate genotype and phenotype data on a large scale, using orthologies for cross-species phenotypes. The focus lies on the uptake of quantitative and descriptive RNAi data and ontologies of phenotypes, assays and cell-lines. Then, the results of a study are presented in which the large set of phenotype data from PhenomicDB is taken to predict gene annotations. Text clustering is utilized to group genes based on their phenotype descriptions. It is shown that these clusters correlate well with indicators for biological coherence in gene groups, such as functional annotations from the Gene Ontology (GO) and protein-protein interactions. The clusters are then used to predict gene function by carrying over annotations from well-annotated genes to less well-characterized genes. Finally, the prototype PhenoMIX is presented, integrating genotype and phenotype data with clustered phenotypes, orthologies, interaction data and other similarity measures. Data grouped by these measures are evaluated for theirnpredictiveness in gene functions and phenotype terms.

There are analyzed the previous projects, the international regulation and the existing platforms. Departing from the perspective of the user, the efficiency of the indexation is analyzed by a thematic area of wide root in the country, but of low implantation between the digital resources: the Naval and Maritime History. One concludes that a direct relation exists between the incorporation of the keywords and the metadata in the process of recovery of information, confirming that attends to a bad semantics of the indexed words, there is demonstrated that the repositories that more volume of documents they contain, are those who return a minor number of results, and specifically in the results of Naval and Maritime History we verify that, the location of the digital objects is related to the geographical place. A series of recommendations offer to improve this situation in three key points the creation, organization and maintenance of a digital repository.

Testo completoLa mejora de la calidad de los cuidados en base a una práctica basada en la evidencia (PBE) es uno de los restos planteados en la sanidad y la enfermería actual.Existe un importante vacío en cuanto a intervenciones formativas diseñadas y evaluadas en el contexto asistencial, así como la falta de herramientas que faciliten el proceso de búsqueda bibliográfica y la gestión de la información. En la presente investigación se ha diseñado una aplicación informática, EviCur (www.evicur.cat). El objetivo es evaluar la efectividad del uso de la aplicación EviCur, en relación al grado de implementación de la PBE basado en el logro en competencias informacionales y la utilización de los resultados de investigación sobre la práctica clínica. La presente investigación se ha llevado a cabo en la comarca de Osona (Barcelona) entre los meses de septiembre de 2013 y junio de 2014, en profesionales de enfermería que desarrollan la actividad laboral en dicha comarca. Se ha planificado un diseño cuasi-experimental pre-test y post-test de 2 grupos, un grupo experimental (uso de EviCur) y un grupo de comparación no equivalente (no uso de EviCur). El uso de EviCur facilita el acceso a la información científica e incrementa el nivel de PBE a través de aumentar el logro en las competencias informacionales de los profesionales de enfermería, principalmente en aquellos que han concluido una búsqueda bibliográfica. EviCur es la aplicación única en el ámbito de las TIC con el objetivo de facilitar el proceso de búsqueda bibliográfica, que ha mostrado su efectividad, no obstante debe continuar su desarrollo, mejorando la interactividad y implementando nuevas funciones.Para implementar la PBE en los cuidados de enfermería, las instituciones deben diseñar estrategias que combinen de forma simultánea la formación informacional e informática, particularizando las estrategias según el perfil profesional y acompañadas simultáneamente de otras medidas de soporte institucionales que faciliten la puesta en práctica de las propuestas de innovación, surgidas de los profesionales asistenciales.
The improvement in the quality of the healthcare focused on the Evidence-Based Practice (EBP) is one of the current fields in the health system and, more specifically, in the nurse area.There is a significant gap in terms of training interventions which are designed and evaluated in the healthcare setting system, as well as an important lack of tools to ease this searching process for resources and the way information is managed. In the present PhD, a computer application website, which is called EviCur (www.evicur.cat). The main goal of this study consists in evaluating the effectiveness when using the EviCur application in relation to the degree in which the PBE is implemented according to the Information Competencies on the one hand, and to the data extracted from the research results in clinical practice on the other. The current study has been carried out in the region of Osona (Barcelona) between September 2013 and June 2014 by nurse practitioners who work in the healthcare system in this area. A quasi-experimental pre-test and post-test system was designed for 2 groups; one of them was experimental (EviCur users) and the other one was a comparison group non-equivalent (EviCur non-users). The use of EviCur eases the access to scientific information and increases the level of EBP, because it raises the information competences of the nurse practitioners, especially those practitioners who have completed a literature research. EviCur is the only available application in the ICT field with the aim of easing the process of literature research. Up to now, it has been effective, but it is necessary to continue its development, improving interactivity and implementing new functions. In order to implement the EBP in the nurse field, institutions must design strategies that simultaneously combine the informational and computer training and they pay special attention to the professional profiles. Moreover, these strategies need to go together with other measure of institutional support so as to facilitate the application of these innovative practices, arising from healthcare professionals.

Testo completoMotivación A pesar de la diseminación de publicaciones científicas, la mayor parte de la información no está necesariamente interconectada ni es procesable por máquinas. Esto, junto con el continuo crecimiento de la producción científica, dificulta tareas como categorizar y comparar documentos científicos. Resultados Biotea ofrece un modelo semántico junto con los procedimientos para representar metadatos, referencias y contenido, enriqueciéndolos con anotaciones semánticas en el área de la Biomedicina (es decir identificación y extracción de expresiones asociadas con conceptos ontológicos). Biotea se utilizó para modelar artículos completos del subconjunto abierto de PubMed Central. Para aprovechar esta infraestructura semántica desarrollamos Biolinks. Biolinks propone una reclasificación de los grupos semánticos del Unified Medical Language System utilizada para caracterizar y comparar publicaciones desde un punto de vista semántico. Conclusiones Biotea y Biolinks posicionan las publicaciones en la nube del Linked Open Data, facilitando interoperabilidad y consultas, contribuyendo además al descubrimiento de conocimiento basado en literatura.

Testo completoData-center energy consumption is nowadays a major issue. Intra-data-center networking accounts almost for a quarter of the data-center total power consumption. Optical switching technologies could provide higher power efficiency than current solutions based on electrical-packet switching. This work focuses on optical-packet-switched networks for small- and medium-size data centers. It takes part of the EPOC (Energy-Proportional and Opportunistic Computing) project, which main interest consists on reducing the overall power consumption of a data center partially powered by renewable sources. A key assumption is that our data center does not rely on a dedicated storage network, in order to reduce the consumption of those interconnections. In addition, with the aim of being able to turn off some servers according to the workload and the available energy, the bit rate must be close to 100 Gbit/s. We have chosen, after studying the state of the art of data-center interconnects, a purely passive network architecture based on fast-wavelength-tunable transmitters under the name of POPI.We study POPI's limitations due to its components (insertion loss, tuning range and channel spacing). We then propose an extension called E-POPI that allows to increase the number of connected servers by using several transmission bands. For larger data centers, we propose POPI+, a two-stage infrastructure for intra- and inter-rack communications operating in the C and L bands, respectively. The connection between both stages is done via a transparent gateway in one direction and an opaque one in the other. We discuss different control solutions for both stages.The feasibility of these architectures depends on, among other factors, dealing with bit-rate increasing and power losses of a passive interconnect. Coherent long-distance-transmission techniques are not currently suited to data centers. We therefore studied PAM 4 and 8 modulation formats with direct detection. On one hand, by simulation, with different bit rates (up to 112 Gbit/s) and receivers (PIN, APD and SOA-PIN) and, on the other hand, experimentally, at 12 and 18 Gbit/s. We have developed a method for compensating the distortions generated by the different network components. Our method takes into account a good tradeoff between correction accuracy and computation time.Simulation results allow us to determine the amount of insertion loss that may be supported. We then combine these results with the limitations of transmitters-tuning range and channel spacing using multiple of 12.5 GHz slots for dimensioning the proposed architectures. POPI, E-POPI and POPI+ interconnects allow the connection of 48, 99 and 2352 entities, respectively, at 112 Gbit/s. Our assessments take into account a potential dispersion of the characteristics of the main architecture components

Testo completoEns trobem a l’era de la informació on la majoria de les dades s’emmagatzemen en format digital. Per tant, la gestió de documents i vídeos digitals requereix el desenvolupament de tècniques eficients per a l’anàlisi automàtic. Entre elles, la captura de la similitud o dissimilitud entre diferents imatges de documents o fotogrames de vídeo és extremadament important. En aquesta tesi, analitzem, a diverses resolucions d’imatge, el comportament de tres famílies diferents de mesures basades en similitud d’imatges i aplicades a la classificació de factures. En aquests tres conjunt de mesures, el càlcul de la similitud entre dues imatges es basa, respectivament, en les diferències d’intensitat, en la informació mútua, i en la distància de compressió normalitzada. Degut a que els millors resultats s’obtenen amb les mesures basades en la informació mútua, es procedeix a investigar l’aplicació de tres generalitzacions de la informació mútua basades en Tsallis en diferents índexs entròpics. Aquestes tres generalitzacions es deriven respectivament de la distància de Kullback-Leibler, la diferència entre l’entropia i entropia condicional, i la divergència de Jensen-Shannon. En relació al processament de vídeo digital, proposem dos enfocaments diferents de teoria de la informació basats respectivament en la informació mútua de Tsallis i en la divergència de Jensen-Tsallis, per detectar els límits d’un pla cinematogràfic en una seqüència de vídeo i per seleccionar el fotograma clau més representatiu de cada pla. Finalment, l’entropia de Shannon s’ha utilitzat habitualment per quantificar la informativitat d’una imatge. El principal inconvenient d’aquesta mesura és que no té en compte la distribució espacial dels píxels. En aquesta tesi, s’analitzen quatre mesures de teoria de la informació que superen aquesta limitació. Tres d’elles (entropy rate, excess entropy i erasure entropy) consideren la imatge com un procés estocàstic estacionari, mentre que la quarta (partitional information) es basa en un canal d’informació entre les regions d’una imatge i els intervals de l’histograma
