Actividades de crianças do pré-escolar e educadores de infância com o computador em portugal

Muito se tem escrito hoje sobre a integração das tecnologias de informação e comunicação (TIC) na escola e diversas pesquisas têm vindo a demonstrar a importância da familiarização da criança desta idade com a tecnologia, quer porque esta faz parte inquestionável do mundo que a rodeia, quer pela relevância educativa das experiências que lhe pode proporcionar. No entanto existem muito poucos estudos que nos descrevam e analisem processos efectivos de integração da tecnologia na Escola em geral, e ao nível da educação Pré-Escolar em particular. Este foi o ponto de partida da nossa investigação, verificar as práticas de crianças e Educadores de Infância com as TIC, mais especificamente o computador, em Portugal. Elaborámos um questionário que foi enviado, via correio electrónico, para Educadores de Infância de todo o país e como forma de triangulação de dados foram realizadas observações em dois jardins-de-infância, mais concretamente nas aulas de informática das crianças do pré-escolar. Terminamos com conclusões baseadas nos dados recolhidos e algumas considerações finais sobre o tema

Oral and maxillofacial lesions in older individuals and associated factors : a retrospective analysis of cases retrieved in two different services

Studies on the oral and maxillofacial lesions (OMLs) in older people usually assess data of laboratory services and data from oral medicine clinic have been poorly described. The aim of this study was to describe and to compare OMLs in older individuals considering two data sources, besides to assess associated factors with the three most frequent lesions. A retrospective study was conducted with individuals aged 60 years or older. Data of individuals and lesions reported in both services were collected. Univariate analysis was used to test the association between the occurrence of the lesion and the independent variables. The level of significance was set at 5%. A total of 1,695 (37.3%) records were from the Oral Medicine clinic and 2,848 (62.7%) from the Laboratory service. Inflammatory/reactive lesion group was the most frequent in both services (40.4% in Oral Medicine Clinic and in 44.2% Laboratory). The second and third groups of lesions in the Oral Medicine clinic were infectious diseases (18.5%), and variations of normality (10.8%), while in the laboratorial service were the malignant neoplasms (17.6%) and potentially malignant disorders (13.3%). Differences between services regarding the frequency of lesion groups occurred (p<0.05), except for pigmented (p=0.054) and infectious (p=0.054) groups. Females (OR: 2.08; CI: 1.81?2.39) and individuals who wore a removable prosthesis (OR: 3.99; CI: 2.83?5.62) were also likely to have inflammatory fibrous hyperplasia. Old?old individuals (OR: 1.70; CI: 1.30?2.21), male (OR: 3.63; CI: 3.00?4.39), smoking (OR: 6.05; CI: 4.84?7.56) or alcohol use (OR: 3.95; CI: 3.12?5.01) were likely to have squamous cell carcinoma. The results showed different frequencies of OMLs in older individuals according to the data sources and age group. The findings are important to direct public policies for this age group

LaMMos - Latching Mechanism based on Motorized-screw for Reconfigurable Robots and Exoskeleton Suits

Reconfigurable robots refer to a category of robots that their components (individual joints and links) can be assembled in multiple configurations and geometries. Most of existing latching mechanisms are based on physical tools such as hooks, cages or magnets, which limit the payload capacity. Therefore, robots re- quire a latching mechanism which can help to reconfigure itself without sacrificing the payload capability. This paper presents a latching mechanism based on the flexible screw attaching principle. In which, actuators are used to move the robot links and joints while connecting them with a motorized-screw and dis- connecting them by unfastening the screw. The brackets used in our mechanism configuration helps to hold maximum force up to 5000N. The LaMMos - Latching Mechanism based on Motorized- screw has been applied to the DeWaLoP - Developing Water Loss Prevention in-pipe robot. It helps the robot to shrink its body to crawl into the pipe with minimum diameter, by recon- figuring the leg positions. And it helps to recover the legs positions to original status once the robot is inside the pipe. Also, LaMMos add stiffness to the robot legs by dynamically integrate them to the structure. Additionally, we present an application of the LaMMos mechanism to exoskeleton suits, for easing the mo- tors from the joints when carrying heavy weights for long periods of time. This mechanism offers many interesting opportunities for robotics research in terms of functionality, pay- load and size.Comment: 14 pages, 15 figure

POTENCIAIS INTERAÇÕES MEDICAMENTOSAS EM UM CENTRO DE ATENDIMENTO PSICOSSOCIAL (CAPS) DO CENTRO-OESTE.

Introdu&ccedil;&atilde;o e objetivos: As altas taxas de prescri&ccedil;&atilde;o de psicof&aacute;rmacos nos Centros de Aten&ccedil;&atilde;o Psicossocial (CAPS)1, associada aos seus elevados &iacute;ndices de intera&ccedil;&otilde;es medicamentosas2 exigem a investiga&ccedil;&atilde;o da terapia farmacoterap&ecirc;utica e potencialidades que possam comprometer o quadro cl&iacute;nico das pessoas com transtornos mentais3. Assim almeja-se identificar e relacionar a gravidade das principais intera&ccedil;&otilde;es medicamentosas entre usu&aacute;rios de um CAPS situado no interior do centro-oeste do Brasil. Metodologia: Estudo observacional transversal, com dados secund&aacute;rios em prontu&aacute;rio de usu&aacute;rios do sistema semi-intensivo, realizado no m&ecirc;s de novembro de 2014, aplicando-se a ferramenta Micromedex&reg; Solutions. Aprova&ccedil;&atilde;o Comit&ecirc; de &Eacute;tica 523.834/14. Resultados e discuss&otilde;es: Analisou-se 228 prontu&aacute;rios, que identificou a prescri&ccedil;&atilde;o de 669 medicamentos, com preval&ecirc;ncia de psicof&aacute;rmacos (86,09%). Os esquemas terap&ecirc;uticos individuais abordaram 181 (79,39%) multiterapias, com aus&ecirc;ncia de intera&ccedil;&otilde;es em 31 (17,12%) destas, enquanto 150 (82,88%) apresentaram de 1 (4%) a 11 (1,33%) intera&ccedil;&otilde;es, resultando 370 no total e m&eacute;dia aproximada de 2,09 intera&ccedil;&otilde;es por prescri&ccedil;&atilde;o m&eacute;dica individual. Quanto a gravidade, evidenciou-se 6 (1,62%) casos de contraindica&ccedil;&atilde;o, todos resultante da associa&ccedil;&atilde;o da ziprazidona com outros f&aacute;rmacos (prometazina, olanzapina, haloperidol, fluoxetina). Ainda, 264 (71,35%) foram consideradas importantes, 85 (22,97%) moderadas e apenas 15 (4,06%) relatadas como intera&ccedil;&otilde;es secund&aacute;rias, indicando uma intera&ccedil;&atilde;o leve de menor relev&acirc;ncia cl&iacute;nica. O risco de prolongamento do intervalo QT esteve presente em 156 (42,16%) das intera&ccedil;&otilde;es, resultado este contribuinte para a afirma&ccedil;&atilde;o da correla&ccedil;&atilde;o positiva entre o n&uacute;mero de psicotr&oacute;picos usados e o aumento da dispers&atilde;o do QT4. Conclus&otilde;es: Os resultados demonstrados revelam a necessidade da interven&ccedil;&atilde;o farmac&ecirc;utica no servi&ccedil;o de aten&ccedil;&atilde;o &agrave; sa&uacute;de mental, com uma participa&ccedil;&atilde;o mais efetiva do profissional farmac&ecirc;utico no acompanhamento da terap&ecirc;utica destes pacientes, frente ao quantitativo de intera&ccedil;&otilde;es medicamentosas e suas gravidades evidenciadas

Mãe, cadê o bebê? Repercussões do nascimento prematuro de um irmão

O objetivo deste artigo foi investigar as repercussões do nascimento prematuro do bebê sobre o(s) seu(s) irmão(s), sob a perspectiva materna, durante a internação do recém-nascido na Unidade de Terapia Intensiva Neonatal. O estudo contou com a participação de 37 mães, entrevistadas no 15º dia após o parto. Elas responderam a instrumentos que contemplaram dados demográficos familiares, informações clínicas do bebê e da mãe, e a experiência da maternidade no contexto da prematuridade. A entrevista sobre maternidade continha questões acerca do irmão do bebê, cujas respostas foram examinadas a partir de análise de conteúdo qualitativa. Os resultados revelaram alteração na rotina dos irmãos em razão da maior ausência materna. Os sentimentos e reações dos irmãos incluíram questionamentos, preocupações, ciúme e ansiedade, ao lado de contentamento e curiosidade. A visita do irmão ao bebê prematuro não foi permitida por alguns hospitais. Evidencia-se a importância de os irmãos serem atendidos em suas necessidades de cuidado nesse período de hospitalização do bebê

Variable stars in the VVV globular clusters. II. NGC6441, NGC6569, NGC6626 (M28), NGC6656 (M22), 2MASS-GC02, and Terzan10

© ESO 2021. This is the accepted manuscript version of an article which has been published in final form at https://doi.org/10.1051/0004-6361/202140546Context. The Galactic globular clusters (GGCs) located in the inner regions of the Milky Way suffer from high extinction that makes their observation challenging. High densities of field stars in their surroundings complicate their study even more. The VISTA Variables in the Via Lactea (VVV) survey provides a way to explore these GGCs in the near-infrared where extinction effects are highly diminished. Aims. We conduct a search for variable stars in several inner GGCs, taking advantage of the unique multi-epoch, wide-field, near-infrared photometry provided by the VVV survey. We are especially interested in detecting classical pulsators that will help us constrain the physical parameters of these GGCs. In this paper, the second of a series, we focus on NGC 6656 (M 22), NGC 6626 (M 28), NGC 6569, and NGC 6441; these four massive GGCs have known variable sources, but quite different metallicities. We also revisit 2MASS-GC 02 and Terzan 10, the two GGCs studied in the first paper of this series. Methods. We present an improved method and a new parameter that efficiently identify variable candidates in the GGCs. We also use the proper motions of those detected variable candidates and their positions in the sky and in the color-magnitude diagrams to assign membership to the GGCs. Results. We identify and parametrize in the near-infrared numerous variable sources in the studied GGCs, cataloging tens of previously undetected variable stars. We recover many known classical pulsators in these clusters, including the vast majority of their fundamental mode RR Lyrae. We use these pulsators to obtain distances and extinctions toward these objects. Recalibrated period-luminosity-metallicity relations for the RR Lyrae bring the distances to these GGCs to a closer agreement with those reported by Gaia, except for NGC 6441, which is an uncommon Oosterhoff III GGC. Recovered proper motions for these GGCs also agree with those reported by Gaia, except for 2MASS-GC 02, the most reddened GGC in our sample, where the VVV near-infrared measurements provide a more accurate determination of its proper motions.Peer reviewe

Vaccinia Virus Infection in Monkeys, Brazilian Amazon

To detect orthopoxvirus in the Brazilian Amazon, we conducted a serosurvey of 344 wild animals. Neutralizing antibodies against orthopoxvirus were detected by plaque-reduction neutralizing tests in 84 serum samples. Amplicons from 6 monkey samples were sequenced. These amplicons identified vaccinia virus genetically similar to strains from bovine vaccinia outbreaks in Brazil
