El bibliotecario, facilitador informático de los nuevos medios de adquisición del conocimiento

The Technological changes and thw information exponential growth are factors that determining that information professionals must adquiere new managing information skills For this reason, the Institute of Superior Technical Formation N°13 considers important that their students adquiere technological and information management habilities in order to manage a big growthing mass of information in differents electronic formats The IFTS 13 technogical area´s teachers consider these competences must cover all the technological skills required in order to identify proper availables tools necessary to provide access for library use

Una aproximación a un análisis comparativo entre tesauros y ontologías en el área de las Ciencias Astronómicas

The present work makes a brief comparative analysis between thesauri and ontologies, their similarities, their differences and the possibility to convert thesauri into ontologies. It examines several thesauri and one ontology from the astronomical field with the purpose to evaluate parameters like granularity, level of terms reutilization for different systems, etc

¿Cómo nos ven y cómo nos vemos en el mundo de la información? Del bibliotecario burocrático al profesional Web 2.0

In the Information Society, based in the digital access to information released from physical carriers, the new information professional´s role must orientate to active information management and requires to leave behind the traditional librarian´s stereotype as a passive knowlegde custodian. A survey was made and the results suggest the librarians thinks that their images is perceived as irelevant by society, while they perceived their own image as trascendent as mediators between information source, print and electronic, and the users. In order to achieve the change of this negative image, is necessary to emphasize the educational information professional´s role in the use of the new information technologie

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Una aproximación a la relación entre la propiedad intelectual y la probemática jurídico informática en el mundo bibliotecológico

Informatics has produced an economic, social and legal impact in Human History. For Information Science´s professionals, this impact has the meaning of a big change of the way of every day´s work. In this Age, marked by the broader role of digital sources in companies, it is necessary start to study this issue also with the perspective of Informatic Law, with the purpose to understand the use licens

Revisión de la Clase 52 de la CDU y ontologías en Astronomía

This work investigates differents ways to achieve a UDC 52 Revision. It starts with former revisions, it includes the scheme analysis of an especialized classification on the field and also studies the Ontology of Astronomical Object Types in order to analyze the use of different methods to perform a scheme actualization: It includes the enumerative approach and the analytic-synthetic method (facet analysis
