    Trabalho apresentado em XXX Jornadas Luso-Espanholas de Gestão Científica, 5-8 fevereiro 2020, Bragança, PortugalBig Data é uma área que pretende proporcionar capacidade de processamento dos dados, face ao crescimento exponencial de informação gerada de dia para dia, através de novas tecnologias para recolha, transformação, processamento e análise de dados provenientes de diversas fontes e em diversos formatos. Os desafios do Big Data são significativos, daí terem surgido diversas tecnologias num curto espaço de tempo, o que torna também desafiante a entrada nesta área de estudo/investigação. Este artigo apresenta um projeto de implementação de um laboratório de Big Data, para processamento de dados históricos e em movimento (streaming), cujo propósito é permitir a utilização/exploração das tecnologias associadas em atividades de ensino e investigação. São apresentadas as tecnologias, a arquitetura implementada e testes de processamento de dados realizados para validação da correta configuração e funcionamento do laboratório.Big Data is a field that aims to provide data processing capacity, facing the exponential growth of information generated daily, through new technologies for collecting, transforming, processing and analysing data from various sources and in various formats. The challenges of Big Data are significant, so many technologies have emerged in a short time, making the entry into this area of study / research challenging as well. This paper presents a project for the implementation of a big data laboratory for processing historical and data in motion (streaming), whose purpose is to allow the use / exploitation of associated technologies in teaching and research activities. The technologies, the implemented architecture and data processing tests performed to validate the correct configuration and operation of the laboratory are presented.info:eu-repo/semantics/publishedVersio

    Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

    No full text
    Enquadramento: A maior parte das doenças cardiovasculares, resulta de um estilo de vida inapropriado e de fatores de risco (FR) modificáveis cujo controlo se traduz na redução de complicações fatais e não fatais das doenças cardiovasculares. Objetivos: Determinar a prevalência de FR cardiovascular: fatores sociais, comportamentais e biológicos. Material e Métodos: Estudo transversal efetuado numa Unidade de Cuidados Intensivos Coronários, com 48 doentes, 66,7 % são homens. A média de idades foi de 67.02 anos e 54,2% situam-se na classe etária com mais de 65 anos. Foi utilizado um questionário para recolha de dados sociodemográficos, sociofamiliares e FR. Usamos o qui-quadrado e regressão logística binária no SPSS® 20.0. Resultados: Quanto à prevalência de FR: Hipertensão arterial 66,7%, excesso de peso/obesidade 64,5%, hipertrigliceridemia 62,5%, hipercolesterolemia 56,3%, hiperglicemia/diabetes 29,2%, tabagismo 27,1%, antecedentes familiares prematuros 22,9%. Verificou-se que e 81,2% acumula dois ou mais FR. Quanto a hábitos alimentares, 41,7% apresentam uma alimentação não saudável, 52,1% apresentam sedentarismo e 35,4% um consumo elevado de álcool. Constata-se maior consumo de álcool e tabagismo no homem e a mulher perceciona melhor apoio social. Identificaram-se inter-relações entre a alimentação não saudável e hipertensão arterial (p=0,035), entre a hipertrigliceridemia e a hipercolesterolemia (p=0,007), e entre hipercolesterolemia e a hipertrigliceridemia (p=0,004). Conclusões: A magnitude das prevalências dos FR sugere que é preciso intensificar a promoção da saúde e a prevenção cardiovascular de preferência seguindo uma estratégia populacional. Devem também ser traçadas estratégias de prevenção secundária eficazes. Palavras-chave: Doenças cardiovasculares, fatores de risco, síndrome coronária aguda, estilos de vida.ABSTRACT Context: Most cardiovascular diseases stem from an inappropriate lifestyle and from modifiable risk factors (RF) whose control results in the reduction of fatal and non-fatal complications of cardiovascular diseases. Objectives: To determine the prevalence of cardiovascular risk factors: social factors, behavioral factors and biological factors. Material and Methods: Cross-sectional study developed in a Coronary Intensive Care Unit among 48 patients, from which 66,7 % are male. The average age was 60.02 years old and 54,2% are aged 65 years old and above. A questionnaire was used to collect socio-demographic data, socio-family data and risk factors (RF). The chi-squared test and binary logistic regression were used in SPSSr 20.0. Results: As far as the prevalence of risk factors is concerned: High blood pressure 66,7%, overweight/ obesity 64,5%, hypertriglyceridemia 62,5%, hypercholesterolemia 56,3%, hyperglycemia/ diabetes 29,2%, smoking 27,1%, premature family history 22,9%. It was found that 81,2% present two or more risk factors (RF). As far as eating habits are concerned, 41,7% present an unhealthy diet, 52,1% present sedentarism and 35,4% heavy alcohol consumption. Alcohol consumption and smoking is heavier in men and women perceive a better social support. It were established interrelationships between an unhealthy diet and high blood pressure (p=0,035), between hypertriglyceridemia and hypercholesterolemia (p=0,007) and between hypercholesterolemia and hypertriglyceridemia (p=0,004). Conclusions: The magnitude of the prevalence of risk factors (RF) suggests that it is necessary to reinforce the promotion of health and the cardiovascular prevention preferably pursuing a population-based strategy. Effective secondary prevention strategies should also be outlined. Keywords: Cardiovascular diseases, risk factors, acute coronary syndrome, lifestyles

    The modifying role of major cardiovascular risk factors in the association between retirement and cardiovascular disease: Results from SHARE Portugal

    No full text
    Background: Despite the actual demographic trends and the global burden of cardiovascular diseases, there is little knowledge concerning the effects of retirement on this health outcome. Objective: We aimed to quantify the associations between retirement, and retirement age, with cardiovascular disease (heart disease and stroke) in the Portuguese population. Methods: We used data from the first Portuguese wave of the Survey of Health Ageing and Retirement in Europe. Logistic regression was applied to quantify the associations. The major risk factors for cardiovascular diseases and several features of retirement were considered as possible confounders or effect modifiers. Analysis was restricted to retirees in retirement process (retired for 5 years or less) and not retired because of illness. Results: An opposite direction of the association between retirement and heart disease was observed according to hypertension status, although not significant. Early retirement increased the odds of having a stroke, merely in individuals without heart disease (OR = 8.87; 95% CI 1.63-48.26). On the contrary, in individuals with heart disease, decreased the odds of having a stroke (OR = 0.08; 95% CI 0.01-0.68). Conclusions: Our findings suggest that retirement and retirement age may be beneficial or harmful, respectively, in the presence or absence of major risk factors for heart disease and stroke. We suggest that work-related stress affecting differently workers with and without these risk factors may eventually explain these findings.This paper used data from SHARE Wave 4 (DOI: 10.6103/SHARE.w4.710), see Borsch-Supan et al. ¨ for methodological details [14, 32, 33].

    O principal objectivo deste estudo consistiu na determinação das propriedades psicométricas da versão portuguesa da Dutch Pictorial Scale of Perceived Competence and Social Acceptance in Children with Cerebral Palsy. Participaram neste estudo 108 crianças (60 rapazes e 48 raparigas) com paralisia cerebral, com idades entre os 4 e os 9 anos, distribuídas em hemiplegicas, diplégicas e tetraplégicas e com um QI igual ou superior a 70. A maioria (n=98) frequentava o ensino regular, enquanto apenas 10 frequentavam escolas especiais. O instrumento foi aplicado num segundo momento a 41 das crianças, com um intervalo máximo de duas semanas. Os resultados da correlação de Pearson relativamente aos dois momentos (entre 0.80 e 0.98) bem como o valor do alfa de Cronbach (entre 0.69 e 0.93) evidenciam uma boa fiabilidade da versão portuguesa. Também os valores das inter-correlações entre as quatro subescalas (r=0.60 ou superior) bem como os valores médios das respostas das crianças em função de diferentes características (idade, sexo, condição médica) para as diferentes subescalas apoiam a validade interna do instrumento. Em suma, os resultados do nosso estudo, na sua globalidade, parecem confirmar as propriedades psicométricas da versão portuguesa da Dutch Pictorial Scale, pelo que esta parece constituir-se como um instrumento fiável e válido para a avaliação do modo como as crianças portuguesas com Paralisia Cerebral se percebem no domínio cognitivo, físico e social.The main purpose of this study was to examine the psychometric properties of the Portuguese version of the Dutch Pictorial Scale of Perceived Competence and Social Acceptance in Children with Cerebral Palsy. The sample was made up of 108 children (60 boys and 48 girls) with cerebral palsy, aged between 4 and 9 years, who suffered hemiplegia, diplegia or quadriplegia and had an IQ of 70 or higher. Most of the children (n=98) attended regular schools (integrated in kindergarten or primary school); indeed, only 10 children attended special schools for children with special needs. A sub-sample of 41 children filled out the scale in two different moments, separated one to two weeks maximum. The results of Pearson correlations between the two administrations (ranging 0.80 to 0.98) and the Cronbach's alpha (ranging 0.69 to 0.93) showed good reliability of the Portuguese version of the Dutch Pictorial Scale. Moreover, the inter-correlations between the four subscales (r=0.60 or higher) as well the mean scores associated by children with different characteristics (age, sex, medical condition) to the different subscales supported the internal validity of the instrument. Therefore, this study provides initial evidence about the psychometric properties of the Portuguese version of the Dutch Pictorial Scale, which is why its use is recommended to assess the perceived competence and social acceptance of Portuguese children with cerebral palsy
