Conceitua Realidade Aumentada do ponto de vista histórico de vários autores e como surgiu esse segmento através da evolução tecnológica até os dias atuais. Aborda seu funcionamento, como também, seus sistemas e aplicações em diversos campos de pesquisas e estudos científicos. Diferencia Realidade Aumentada de Realidade Virtual, visando melhor esclarecimento entre ambas na intenção de descaracterizá-las com uma única “realidade”. Apresenta a Realidade Aumentada e sua aplicação dentro de um contexto de uma unidade de informação, promovendo uma melhor interação com os usuários e as adaptações pelas quais as bibliotecas terão que passar futuramente para se adequarem a “explosão” tecnológica. Descreve o funcionamento da biblioteca ARToolKIT, baseada em RA e suas principais etapas de funcionamento para visualização de objetos virtuais em 3D. Exemplifica os benefícios que uma unidade de informação, que utiliza Realidade Aumentada, promove aos usuários portadores de deficiência, além de sua inclusão no meio digital e sua inserção no mercado de trabalho

Resumo:
The goal of this paper was to search the state of the art from the Digital Libraries in Architecture and Urbanism in the Higher Education Institutions (IES) through conceptualizations and showing the importance of Digital Libraries in the disclosure and easing of information transferring. Questions about digital information architecture, usability, digital preservation and accessibility were approached. The research was made in the websites of Brazilian Universities, firstly to identify the institutions which offered the Architecture and Urbanism course, focusing on postgraduate education. After identifying the offering, the research was done by analyzing the contents, storage and dissemination and access to information, these libraries. It was found that the digital libraries are increasingly and taking part of organizations and educational institutions focusing on the knowledge dissemination releasing digitally information that may be needed for institution or the individual. A monitoring was done over of the physical and computational restructuring of the Board of Studies and Research in Architecture and Urbanism (Câmara de Estudos e Pesquisa em Arquitetura e Urbanismo, CEPAU), from the Architecture and Urbanism Course of the Federal University of Rio Grande do Norte (UFRN), showing the need of installing a Digital Library to integrate the databases of PPGAU s research groups, which today remain independent, with no interface among themselves. The research chosen area was Architecture and Urbanism, because there is a gap and little documentation about digital libraries in this area

Flowering is a fundamental process in the life cycle for plant. This process is marked by vegetative to reproductive apical meristem conversion, due to interactions between several factors, both internal and external to plant. Therefore, eight subtractive libraries were constructed using apical meristem induced or not induced for two contrasting species: Solanum lycopersicum cv. Micro-Tom and Solanum pimpinellifolium. Several cDNAs were identified and among these, were selected two cDNAs: one homologous cDNA to cyclophilin (LeCYP1) and the other to Auxin repressed protein (ARP). It has observed that LeCYP1 and ARP genes are important in the developmental process to plants. In silico analysis, were used several databases with the exclusion criterion E-value <1.0x10-15. As a result, conservation was observed for proteins analyzed by means of multiple alignments and the presence of functional domains. Then, overexpression cassettes were constructed for the ARP cDNA in sense and antisense orientations. For this step, it was used the CaMV35S promoter. The cDNA orientation (sense or antisense) in relation to the promoter was determined by restriction enzymes and sequencing. Then, this cassette was transferred to binary vector pZP211 and these cassettes were transferred into Agrobacterium tumefaciens LBA4404. S. lycopersicum cv. Micro-Tom (MT) and MT-Rg1 plants were transformed. In addition, seedlings were subjected to hormone treatments using a synthetic auxin (- naphthalene acetic acid) and cyclosporin A (cyclophilin inhibitor) treatments and it was found that the hormone treatment there were changes in development of lateral roots pattern, probably related to decreases in auxin signaling caused by reduction of LeCYP1 in MT-dgt plants while cyclosporin A treatments, there was a slight delay in flowering in cv. MT plants. Furthermore, assay with real-time PCR (RT-qPCR) were done for expression level analysis from LeCYP1 and ARP in order to functionally characterize these sequences in tomato plants.

Throughout the last years, the increasing use of Technologies of nformation and Communication (TICs) have stimulated a new gamma of informational necessities. The digital environments favor the transposition of the conventional limits of representation and dissemination of the registered knowledge, incorporating new elements to the processes of production, organization and recovery of information. Considering the ontologies as a new and riveting category of systems of representation of knowledge, we searched bases that allow to analyze the approaches of this new computational approach with the instruments and methods of Knowledge Organization, starting from presentation of the ontology OIR, designed for the representation and exchange of referential informations of academic papers, investigating in what scale the area of Information Science can contribute to the development of ontologies and analyzing the consequences of its use in digital libraries.

This article analyzes the specific features and processes of indexing and classification performed in school libraries to process and retrieve information from their collections. Subject languages used in Spanish, Portuguese and Brazilian Portuguese school libraries are also analyzed. To achieve this goal, the concept of school library was analyzed, its function was studied and the techniques and tools that allow the information organization were examined. Among the tools, we studied the Subject Headings Lists for children and juveniles’ books and the Subject Headings List for public libraries, the Universal Decimal Classification System (paperback edition) or the classification by fields of interest and specialized thesauri like the Tesauro de la Educación UNESCO-OIE and the TesauroEuropeo de la Educación.

La presentación pretende dar cuenta del proceso de desarrollo de la investigación 'Estudio sobre las bibliotecas escolares argentinas 2008/2009' que fuera parte de un proyecto regional coordinado por OEI/España junto a equipos de Brasil, Chile y Méjico, con el objetivo de evaluar la situación de las bibliotecas escolares en dichos países. Se intenta delinear el proceso conjunto de construcción de un modelo de evaluación para las bibliotecas escolares basado en el reconocimiento de las voces de los distintos actores educativos que confluyen en una biblioteca (directivos, responsables de biblioteca, docentes y alumnos de primaria y secundaria). Para llevarlo adelante se consensuaron dimensiones comunes y en cada una de ellas, indicadores válidos que cada país luego adaptó a las particularidades de su sistema educativo para la estrategia cuantitativa desarrollada a través de encuestas, mientras que la estrategia cualitativa tuvo un alcance diverso en cada país, de acuerdo a sus posibilidades. Asimismo, se describe el estudio argentino desde su propuesta metodológica y se presenta brevemente una herramienta de evaluación, diseñada para el análisis integrado de los datos, que dimos en llamar Indicadores resumen. Estos constituyen una propuesta exploratoria para la elaboración de ciertos supuestos hipotéticos en torno al funcionamiento de las bibliotecas escolares que permite la síntesis de ciertos rasgos que aparecen en los indicadores comunes.

La interoperabilidad entre distintos sistemas de organización del conocimiento (SOC) ha cobrado gran importancia en los últimos tiempos, con el propósito de facilitar la búsqueda simultánea en varias bases de datos o fusionar distintas bases de datos en una sola. Las nuevas normas para el diseño y desarrollo de SOC, la estadounidense Z39.19:2005 y la británica BS 8723-4:2007, incluyen recomendaciones detalladas para la interoperabilidad. También se encuentra en preparación una nueva norma ISO 25964-1 sobre tesauros e interoperabilidad que se agregará a las anteriores. La tecnología disponible proporciona herramientas para este fin, como son los formatos y requisitos funcionales de autoridades y las herramientas de la Web Semántica RDF/OWL, SKOS Core y XML. Actualmente es difícil diseñar y desarrollar nuevos SOC debido a los problemas económicos, de modo que la interoperabilidad hace posible aprovechar los SOC existentes. En este trabajo se revisan los conceptos, modelos y métodos recomendados por las normas, así como numerosas experiencias de interoperabilidad entre SOC que han sido documentadas.

El presente artículo reseña la actividad desarrollada en los últimos 5 años por parte del Equipo de Trabajo Interbibliotecas dedicado a la 'evaluación de unidades de información' de ROBLE, la red de bibliotecas de la UNLP. Este período se inicia con el desarrollo de una aplicación informática destinada a registrar de forma uniforme los datos estadísticos de las bibliotecas para la generación automática de cuadros, tablas y gráficos con indicadores. A partir de la recopilación, procesamiento y análisis regular de esta información, se logró generar una dinámica de trabajo con los datos muy interesante, que gradualmente las bibliotecas cooperantes fueron incorporando como propia dentro de sus propios procesos de autoevaluación, y que en muchos casos logró posicionarlas mejor dentro de sus instituciones. A la vez, al tratarse de una experiencia única en el ámbito de la UNLP, se logró el reconocimiento y la inclusión de estos indicadores en el Anuario estadístico general, que hasta 2008 no incluía datos de las bibliotecas. Las lecciones aprendidas en este tiempo son variadas y positivas: hoy contamos con datos e indicadores uniformes del período 2001-2009, correspondientes a alrededor de 15 bibliotecas, lo que nos permite observar tendencias, visualizar mejor la evolución registrada, resaltar los puntos fuertes y débiles, focalizar los problemas y utilizar toda esta información como una herramienta para la gestión. Pero fundamentalmente, lo que nos parece más valioso de todo esto es haber logrado incorporar esta metodología de trabajo como parte de la práctica cotidiana de las bibliotecas, y de los bibliotecarios.
