Ontologies geogràfiques turístiques de punts d'interès i documents associats

Aquest document exposa la elaboració del Projecte de fi de carrera "Ontologies Turístiques Geogràfiques", corresponent a l'àrea de XML i Web semàntica dels estudis d'Enginyeria Informàtica de la Universitat Oberta de Catalunya que tracta de la creació d'una ontologia turística geogràfica que permeti etiquetar els fitxers que contenguin informació sobre els punts d'interès per a poder representar els aspectes de l'àmbit turístic.

Ontologies turístiques geogràfiques

En els propers anys, la Web semàntica i les tecnologies que porta associades sembla que constituiran els eixos vertebradors d'una nova manera d'entendre la Xarxa. Aquesta deixarà de ser un mer repositori d'informació per a convertir-se en un ens capaç de generar coneixement per si sol, on màquines i usuaris treballin de manera col·laborativa. En aquest treball s'analitzarà l'evolució que ha sofert el mitjà i el significat d'una Web semàntica, passant per algunes de les tecnologies que hi donen suport. Per a entendre com es confereix significat a l'estructura d'una web, s'estudiaran de manera incremental els diferents llenguatges que permeten construir-la: XML, RDF i OWL. L'estructura conceptual que pren la informació, la representació de la qual és codificada amb els llenguatges mencionats anteriorment, es tractarà tant en un vessant teòric com en un de pràctic. Així, s'analitzarà el concepte i el procés de creació d'una ontologia i, mitjançant el programari Protégé, es crearà una taxonomia adequada en l'àmbit del turisme o lleure de muntanya. Un altre aspecte que s'analitzarà en el document és la nova generació de bases de dades que ha sorgit com a conseqüència del nou suport de la informació, on preval la relació que s'estableix entre les dades per sobre d'aquestes. Així doncs, s'estudiaran les característiques bàsiques de les bases de dades XML natives i es farà una breu introducció als llenguatges de modificació i consulta que suporten. Aquests aspectes s'aplicaran de manera pràctica sobre la base de dades eXist, mitjançant l'ús de les instàncies de l'ontologia creada. Finalment es desenvoluparà una aplicació web que permeti portar a la pràctica algunes de les tecnologies estudiades. El context en què se centrarà el cas pràctic serà el mateix que s'ha representat mitjançant l'ontologia i permetrà comprovar el funcionament d'una web explotada de manera semàntica.

Dispersions dans la réalisation autonome des activités de la vie quotidienne (AVQ) dans la démence.

Un premier article présentait la réalisation autonome des activités de la vie quotidienne (AVQ) dans la démence. Cette réalisation est constituée de deux phases : l'articulation du sujet avec l'objectif et le déroulement proprement dit. Dans ce second article, nous présentons une typologie des actions-dispersions, précisant la deuxième phase. Considérant le sujet autonome en lien intentionnel avec l'activité, nous définissons les dispersions comme un désengagement de l'activité. L'analyse des dispersions vise à comprendre plus exactement et de façon différenciée la réalisation des AVQ en cas de démence. Notre approche anthropologique, qui intègre les dimensions psychologiques et comportementales, se démarque des approches comportementaliste et neuropsychologique, en ce sens qu'elle permet d'intégrer les conduites dans leur ordre de réalité et au sein de la structure d'ensemble de l'activité. A partir d'observations visant l'intentionnalité du sujet, nous avons dégagé des types de dispersion, leurs origines - dans le sens de moment d'apparition - et leurs formes. Nous illustrons cette typologie par des exemples extraits d'une prise en soin. Les deux articles se complètent pour présenter un modèle fonctionnel définissant la réalisation des AVQ en cas de démence. Il s'agit d'un schème théorique permettant d'interpréter et d'anticiper le fonctionnement du sujet dément afin de le guider, tout en lui laissant une marge de maîtrise de son milieu quotidien.

La réalisation autonome des activités de la vie quotidienne dans la démence.

A côté de la pratique psychothérapique, de la recherche en laboratoire et des travaux classificatoires, nous proposons une approche anthropologique de la démence. Cette approche combine et coordonne recherche, réhabilitation et transfert des résultats dans les soins. Les activités de la Lebenswelt nous servent de situation d'observation participante. Elles satisfont les conditions nécessaires pour comprendre le patient souffrant de démence comme sujet, agent de ses actions et animé d'une motivation qui lui est propre. C'est à partir du fonctionnement subjectif, constituant une unité Individu-Environnement, que nous pouvons à la fois évaluer l'autonomie, la respecter et la promouvoir. L'étude du cas présenté sert à illustrer cette approche fonctionnelle et à définir trois catégories ancrées dans la réalisation des activités de la vie quotidienne (AVQ) : articulation, lien intentionnel et transition critique. A partir d'extraits d'observations d'une patiente réalisant deux types d'AVQ (prise du repas et toilette-habillage), nous faisons une analyse qualitative des moments-clés correspondant à nos catégories, du point de vue des capacités de la patiente et du point de vue des aides offertes. L'ordre descriptif et catégoriel de notre travail permet de dégager une structure générale en deux phases de la réalisation autonome des AVQ dans la démence.

PERSONAL(ONTO) : Personalizing the Learning Process in Virtual Environments by means of Adaptive Formative Itineraries based on Reusable Learning Objects and Ontologies TIN2006-15107-C02

Personalization in e-learning allows the adaptation of contents, learning strategiesand educational resources to the competencies, previous knowledge or preferences of the student. This project takes a multidisciplinary perspective for devising standards-based personalization capabilities into virtual e-learning environments, focusing on the conceptof adaptive learning itinerary, using reusable learning objects as the basis of the system and using ontologies and semantic web technologies.

What should a virtual University Library environment look like?

Over the past year, the Open University of Catalonia library has been designing its new website with this question in mind. Our main concern has been how to integrate the library in the student day to day study routine to not to be only a satellite tool. We present the design of the website that, in a virtual library like ours, it is not only a website but the whole library itself. The central point of the web is my library, a space that associates the library resources with the student's curriculum and their course subjects. There the students can save the resources as favourites, comment or share them. They have also access to all the services the library offers them. The resources are imported from multiple tools such as Millennium, SFX, Metalib and Dspace to the Drupal CMS. Then the resources' metadata can be enriched with other contextual information from other sources, for example the course subjects. And finally they can be exported in standard, open data formats making them available for linked data applications.

Estudio y construcción de herramientas de validación HTML

The Final Year Project consists of two essentially different parts, which share acommon theme: HTML code validation. The first of these two parts focuses on the study of the validation process. It supplies a brief introduction to the evolution of HTML and XHTML, the new tags introduced in HTML5 and the most common errors found in today's websites. Already developed HTML validation tools are analyzed and examined in detail in order to compare their features and evaluate their performances. Lastly, a comparison of the parsing process in the most common browsers found nowadays is provided. In the second part of the project the focus of the project is shifted towards the development of a XHTML5 validation tool. The input is a XHTML5 file whose content may or may not comply with the W3C specification, and therefore, may or may not be a valid XHTML5 document. The output provided by this tool will be a fixed XHTML5 document and an error log returned in the form of a XML file. Information as to the course of action pursued to fix the error and its location will also be included.

Beyond the Transatlantic Divide: The Multiple Authorities of Standards in the Global Political Economy of Services

This paper explores the plurality of institutional environments in which standards for the service sector are expected to support the rise of a global knowledge-based economy. Despite the careful wording of the World Trade Organization (WTO), a whole range of international bodies still have the capacity to define technical specifications affecting how services are expected to be traded on worldwide basis. The analysis relies on global political economy approaches to extend to the area of service standards the assumption that the process of globalization is not opposing states and markets, but a joint expression of both of them including new patterns and agents of structural change through formal and informal power and regulatory practices. It analyses on a cross-institutional basis patterns of authority in the institutional setting of service standards in the context of the International Organisation for Standardisation (ISO), the European Union, and the United States. In contrast to conventional views opposing the American system to the ISO/European framework, the paper questions the robustness of this opposition by showing that institutional developments of service standards are likely to face trade-offs and compromises across those systems and between two opposing models of standardisation.

A nutritional intervention study with hydrolyzed collagen in pre-pubertal Spanish children: influence on bone modeling biomarkers

Aim: The aim of the study was to investigate the influence of dietary intake of commercial hydrolyzed collagen (Gelatine Royal ®) on bone remodeling in pre-pubertal children. Methods: A randomized double-blind study was carried out in 60 children (9.42 ± 1.31 years) divided into three groups according to the amount of partially hydrolyzed collagen taken daily for 4 months: placebo (G-I, n = 18), collagen (G-II, n = 20) and collagen + calcium (G-III, n = 22) groups. Analyses of the following biochemical markers were carried out: total and bone alkaline phosphatase (tALP and bALP), osteocalcin, tartrate-resistant acid phosphatase (TRAP), type I collagen carboxy terminal telopeptide, lipids, calcium, 25-hydroxyvitamin D, insulin-like growth factor 1 (IGF-1), thyroid-stimulating hormone, free thyroxin and intact parathormone. Results: There was a significantly greater increase in serum IGF-1 in G-III than in G II (p < 0.01) or G-I (p < 0.05) during the study period, and a significantly greater increase in plasma tALP in G-III than in G-I (p < 0.05). Serum bALP behavior significantly (p < 0.05) differed between G-II (increase) and G-I (decrease). Plasma TRAP behavior significantly differed between G-II and G-I (p < 0.01) and between G-III and G-II (p < 0.05). Conclusion: Daily dietary intake of hydrolyzed collagen seems to have a potential role in enhancing bone remodeling at key stages of growth and development.

Andalusian Health Repository: Promoting the scientific health output among professionals and providing citizens with quality health information

The Andalusian Public Health System (Sistema Sanitario Público de Andalucía -SSPA) Repository is the open environment where all the scientific output generated by the SSPA professionals, resulting from their medical care, research and administrative activities, is comprehensively collected and managed. This repository possesses special features which determined its development: the SSPA organization and its purpose as a health institution, the specific sets of documents that it generates and the stakeholders involved in it. The repository uses DSpace 1.6.2, to which several changes were implemented in order to achieve the SSPA initial goals and requirements. The main changes were: the addition of specific qualifiers to the Metadata Dublin Core scheme, the modification of the submission form, the integration of the MeSH Thesaurus as controlled vocabulary and the optimization of the advanced search tool. Another key point during the setting up of the repository was the initial batch ingest of the documents.

MAPI: towards the integrated exploitation of bioinformatics Web Services.

BACKGROUND. Bioinformatics is commonly featured as a well assorted list of available web resources. Although diversity of services is positive in general, the proliferation of tools, their dispersion and heterogeneity complicate the integrated exploitation of such data processing capacity. RESULTS. To facilitate the construction of software clients and make integrated use of this variety of tools, we present a modular programmatic application interface (MAPI) that provides the necessary functionality for uniform representation of Web Services metadata descriptors including their management and invocation protocols of the services which they represent. This document describes the main functionality of the framework and how it can be used to facilitate the deployment of new software under a unified structure of bioinformatics Web Services. A notable feature of MAPI is the modular organization of the functionality into different modules associated with specific tasks. This means that only the modules needed for the client have to be installed, and that the module functionality can be extended without the need for re-writing the software client. CONCLUSIONS. The potential utility and versatility of the software library has been demonstrated by the implementation of several currently available clients that cover different aspects of integrated data processing, ranging from service discovery to service invocation with advanced features such as workflows composition and asynchronous services calls to multiple types of Web Services including those registered in repositories (e.g. GRID-based, SOAP, BioMOBY, R-bioconductor, and others).
