Dauruxu : detección de emociones de personas y sus actividades para el apoyo en la evaluación de factores de riesgo psicosocial

La evaluación de riesgos psicosociales ha desempeñado un papel dominante para garantizar el bienestar y la salud de las personas. No obstante, mecanismos como entrevistas y cuestionarios son susceptibles de obtener resultados sesgados debido a la falta de datos que no se pueden adquirir durante las evaluaciones. Este trabajo propone una arquitectura para identificar actividades y emociones implícitas en los cuestionarios actuales y que tienen el potencial de ser detectadas por cámaras. Mediante visión por computadora, se extraen características de los fotogramas de video los cuales son empleados como predictores para tareas de clasificación. La cuantificación de indicadores basada en la detección de actividades y emociones brindará datos adicionales para respaldar las evaluaciones de riesgo psicosocial.Psychosocial risk assessment has played a dominant role in ensuring the well-being and health of people.

Through computer vision, features are extracted from the video frames which are used as predictors for classification tasks. The quantification of indicators based on the detection of activities and emotions will provide additional data to support psychosocial risk assessments.Magíster en Ingeniería de Sistemas y ComputaciónMagíster en Analítica para la Inteligencia de NegociosMaestrí

Use of the ETV logo and post-verification requirements when marketing a technology verified through the ETV scheme

Environmental Technology Verification (ETV) is a new tool enabling the verification of the performance claims put forward by developers of innovative environmental technologies. The Programme is set up foreseeing the existence of Technical Working Groups (TWGs), one for each technology area active under the Pilot Programme. These are chaired by the JRC and composed by Commission Invited Experts and by Experts representing the Verification Bodies with the overall aim to harmonise and exchange good practices among member states. ETV has a logo inherited from previous ETV FP7 projects, but it is not an official logo of the European Commission. ETV is not a certification nor a labialisation scheme. Therefore the logo should be used in well-defined conditions, specifying clearly what has been verified. This document defines and clarifies all elements relative to the logo and its use: design specifications, uses of the logo under different marketing circumstances and communication purposes. This document, adopted on the date by the TWGs on 08/04/2015, is a guidance document, with the meaning given in the General Verification Protocol of the EU ETV pilot programme (version 1.1), Section A.II.4.3. It has been produced by the EU ETV Technical Working Groups, chaired by the JRC, under the auspices of DG Environment. This document is also deliverable 2.1.6.4 under the Administrative Arrangement 070307/2011/630755/F4 between DG ENV and JRC (ref JRC No. 32937), “Scientific and technical support for the implementation of the EU Environmental Technology Verification (ETV) pilot programme” as modified by amendment 1 signed 16/06/2014.JRC.F.6-Energy Technology Policy Outloo

Guidelines for addressing the interfaces between Technology Areas in the context of the EU-ETV Pilot Program

Environmental Technology Verification (ETV) is a new tool enabling the verification of the performance claims put forward by developers of innovative environmental technologies. As specified in the ETV General Verification Protocol (GVP), the EU-ETV programme, launched in 2011 by DG-ENV is covering three Technology Areas (TAs): Water treatment and monitoring, Materials, waste and resources, Energy Technologies. The verification bodies in charge of performing the verifications have to be accredited for one or more of these 3 TAs or part thereof. Three dedicated Technical Working Groups (TWGs) have been set up in order to provide technical guidance for the technologies falling under these TAs. Although the GVP is providing examples of technologies for each of the TA, the precise frontier between them is not always clear, in particular for technologies that relate to more than one distinct technology areas (e.g. energy efficiency in the domain of water treatment). This document provides guidance on this issue, in order to help decision making and ensure a harmonised approach thought the ETV scheme. This document, adopted on the on the 04/08/2015 by the TWGs, is a guidance document, with the meaning given in the General Verification Protocol of the EU ETV pilot programme (version 1.1), Section A.II.4.3.

Aplicando uma nova versão brasileira do UPSIT no Brasil

Standardized olfactory tests are now available to quantitatively assess disorders of olfaction. A Brazilian-Portuguese version of the University of Pennsylvania Smell Identification Test (UPSIT) is currently being developed specifically for the Brazilian population. The most recent Brazilian-Portuguese version of the UPSIT (UPSIT-Br2) was administered to 88 Brazilian subjects who had no history of neurological or otorhinolaryngological disease. UPSIT-Br2 scores decreased with age, were lower in men than in women, and were lower in subjects with lower income. The degree to which the poorer performance of subjects with lower socio-economic status reflects lack of familiarity with test items is not known. Although this version of the UPSIT provides a sensitive and useful test of smell function for the Brazilian population, a revision of some test items is needed to achieve comparable norms to those found using the North American UPSIT in the United States.Testes padronizados já estão disponíveis para testagem do olfato e uma versão em Português esta sendo desenvolvida para o University of Pennsylvania Smell Identification Test (UPSIT), especificamente para a população brasileira. A versão mais recente deste teste (chamada UPSIT-Br2) foi aplicada a 88 sujeitos brasileiros que não tinham história de qualquer problema neurológico ou otorrinolaringológico. Compatível com dados prévios da literatura, a performance no UPSIT-Br2 decaiu com a idade e foi inferior no genero masculino. Os resultados foram mais baixos em participantes de menor nível sócio-econômico e a relação deste achado com a falta de familiaridade para com os itens do teste não é conhecida. Apesar desta versão do UPSIT poder ser útil para o teste da função olfativa da população brasileira, a revisão de alguns itens se faz necessária para alcançar valores comparáveis aos dados normativos norte-americanos.Reta Lila Weston Trust for Medical Researc

B-LEARNING AND MOODLE AS A STRATEGY IN UNIVERSITY EDUCATION: LATIN AMERICA CASE BY 2017-2022

A documentary review was carried out on the production and publication of research papers concerning studying B-learning, Higher Education, and Moodle as a strategy in university education. The purpose of the bibliometric analysis proposed in this paper was to know the main characteristics of the volume of publications registered in the Scopus database during the period 2017-2022 and to identify the current situation in Ecuadorian institutions regarding the study of the variables mentioned above, achieving the identification of 78 publications in total. The information provided by the said platform was organized employing graphs and figures categorizing the information by Year of Publication, Country of Origin, Area of Knowledge and Type of Publication.

The area of knowledge that made the greatest contribution to the construction of bibliographic material referring to the study of B-learning, Higher Education, Moodle as a strategy in university education was Social Sciences with 41 published documents, and the type of publication that was most used during the period mentioned above was the journal article, representing 56% of the total scientific production

Autonomous RPCs for a Cosmic Ray ground array

We report on the behaviour of Resistive Plate Chambers (RPC) developed for muon detection in ultra-high energy cosmic ray (UHECR) experiments. The RPCs were developed for the MARTA project and were tested on field conditions. These RPCs cover an area of $1.5 \times 1.2\,{m^2}$ and are instrumented with 64 pickup electrodes providing a segmentation better than $20\,$cm. By shielding the detector units with enough slant mass to absorb the electromagnetic component in the air showers, a clean measurement of the muon content is allowed, a concept to be implemented in a next generation of UHECR experiments. The operation of a ground array detector poses challenging demands, as the RPC must operate remotely under extreme environmental conditions, with limited budgets for power and minimal maintenance. The RPC, DAQ, High Voltage and monitoring systems are enclosed in an aluminium-sealed case, providing a compact and robust unit suited for outdoor environments, which can be easily deployed and connected. The RPCs developed at LIP-Coimbra are able to operate using a very low gas flux, which allows running them for few years with a small gas reservoir. Several prototypes have already been built and tested both in the laboratory and outdoors. We report on the most recent tests done in the field that show that the developed RPCs have operated in a stable way for more than 2 years in field conditions.Comment: To appear in the proceedings of the 35th International Cosmic Ray Conference (ICRC2017), Busan, South Korea.

Transições de fase sem termodinâmica

As aplicações de transições de fase vão muito além do contexto da termodinâmica de equilíbrio, de onde surgiu. Nós revisamos um dos principais exemplos de uma transição de fase em um sistema sem termodinâmica, o processo de contato (PC), com ênfase no método de campo médio. Apresentamos um estudo de campo médio aplicado a um modelo para a transmissão da malária em uma população. Discutimos também as novas abordagens da distribuição quase-estacionária e o processo de contato conservativo

Comparison of external, internal flat-to-flat, and conical implant abutment connections for implant-supported prostheses: a systematic review and network meta-analysis of randomized clinical trials

STATEMENT OF PROBLEM: The implant abutment connection interface has been considered one of the major factors affecting the outcome of implant therapy. However, drawbacks of traditional meta-analyses are the inability to compare more than 2 treatments at a time, which complicates the decision-making process for dental clinicians, and the lack of a network meta-analysis. PURPOSE: The purpose of this network meta-analysis was to assess whether the implant abutment connection influences the outcome of implant-supported prostheses. MATERIAL AND METHODS: An electronic search was undertaken to identify all randomized clinical trials comparing the effect of at least 2 different implant abutment connection designs published from 2009 up to May 2020. Outcome variables were implant survival rate, peri-implant marginal bone loss, and biologic and prosthetic complication rates at 12 months after prosthetic loading. Relevant information was extracted, and quality and risk of bias assessed. Pairwise meta-analyses and network meta-analyses based on a multivariate random-effects meta-regression were performed to assess the comparisons (α=.05 for all analyses). RESULTS: For peri-implant marginal bone loss and prosthetic complications, conical interfaces were determined to be the most effective, with significant differences when compared with external hexagonal connections (P=.011 and P=.038, respectively). No significant differences were found among the implant abutment connections in terms of survival and biologic complications (P>.05 in all direct, indirect, and mixed comparisons). CONCLUSIONS: After 1 year of loading, conical connections showed lower marginal bone loss and fewer prosthetic complications than external hexagonal connections. However, the implant abutment connection design had no influence on the implant survival and biologic complication rates
