It encompasses activities related to design, construction, installation, operation, maintenance, renewal, and asset disposal. Asset management ensures the coordination of all activities, resources, and data related to physical assets. Recording and monitoring all maintenance activities is a key part of asset management, often done using work orders (WOs). Technicians typically create WOs using “free text”, which can result in missing or ungrammatical words, making it difficult to identify trends and analyse information. To standardise the terminology used for the same asset maintenance operation, this paper proposes a method that suggests words to technicians as they complete WOs. The word suggestion algorithm is based on past maintenance records, and a Bayesian network-based recommender system adapts to present needs verified by technicians using implicit user feedback. Implementing this system aims to normalise the terms used by technicians when filling in a WO. The corpus for this work comes from asset management records collected in a health facility in Portugal operated by a private company.publishersversionpublishe

    Background: Childhood obesity is understood as a health problem of concern due to the changes it can cause in the development process. Being the physical activity and the built environment important influencers in this process. The authors aimed to analyze studies of the last ten years, checking the relationship between the level of physical activity, the built environment and obesity. Methods: This is a systematic review and meta-analysis, conducted through PubMed, B-on and Web of Science, using the terms (obesity child* AND physi* activit*) AND (obesity child* OR overweight you*) AND (built environment). To evaluate the quality of the studies, the PRISMA tool and the STROBE index were used. Five studies were selected and their data were analyzed by the Comprehensive Meta-Analysis V.3. Results: It can be stated that there is an inverse relationship between the evaluated aspects (obesity, built environment and physical activity), presenting a negative correlation of 0.026 with p = 0.0001. The results of the Z test = -4.050, where the ease and availability of physical activity places are related to childhood obesity levels. Conclusions: Childhood obesity may be inversely related to the built environment, due to the ease and availability of places for physical activity

    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.

    PROT-OVT: Plano Regional de Ordenamento do Territorio do Oeste e Vale do Tejo

    Get PDF
    Os princípios, objectivos e orientações consagrados no Programa Nacional da Política de Ordenamento do Território (PNPOT), aprovado pela Lei n.º 58/2007, de 4 de Setembro, são desenvolvidos nos vários planos regionais de ordenamento do território (PROT) que, por sua vez, constituem um quadro de referência estratégico para os planos directores municipais (PDM). No processo de elaboração e revisão articulada destes três pilares fundamentais do sistema de gestão territorial, em que assenta a política de ordenamento do território e do urbanismo, cabe aos PROT uma posição de charneira fundamental. O significado e as potencialidades dos PROT são ainda significativamente ampliados pela articulação com a revisão dos PDM. Face a uma nova geração de PDM, que se pretendem mais estratégicos, os PROT fornecem um quadro de referência estratégica de longo prazo que permite aos municípios estabelecerem as suas opções de desenvolvimento e definirem regras de gestão territorial compatíveis com o modelo consagrado para a região. Os PROT, além de um pilar da política de desenvolvimento territorial, são documentos fundamentais para a definição dos programas de acção das intervenções co-financiadas pelos Fundos Estruturais e de Coesão da União Europeia. Os PROT são instrumentos de desenvolvimento territorial e de natureza estratégica. Em matéria de conteúdo, estabelecem a estrutura regional do sistema urbano, das redes de infra‑estruturas e dos equipamentos de interesse regional e definem os objectivos e princípios quanto à localização das actividades e os grandes investimentos públicos; as suas normas fixam o quadro estratégico, as orientações de carácter genérico e as directrizes para o ordenamento do território regional. O PROT do Oeste e Vale do Tejo (PROT OVT) visa, neste contexto, a espacialização de estratégias de desenvolvimento territorial nos territórios das NUTS III do Oeste, Médio Tejo e Lezíria do Tejo. Por isso, ocupa, entre o nível nacional e o nível municipal, uma posição chave para a definição das estratégias e das opções de desenvolvimento e de ordenamento regional. O PROT OVT é pois um instrumento privilegiado para promover a reflexão estratégica do desenvolvimento do Oeste e do Vale do Tejo e acolher a tomada de decisão quanto às opções de desenvolvimento territorial [...]info:eu-repo/semantics/publishedVersio

    Building a Portuguese Coalition for Biodiversity Genomics

    The diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to the Atlantic archipelagos, has made it an important repository of biodiversity throughout the Pleistocene glacial cycles, leading to a remarkable diversity of species and ecosystems. This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, land use changes, overexploitation or pathogen (re)emergence. The inventory, characterization and study of biodiversity at inter- and intra-specific levels using genomics is crucial to promote its preservation and recovery by informing biodiversity conservation policies, management measures and research. The participation of researchers from Portuguese institutions in the European Reference Genome Atlas (ERGA) initiative, and its pilot effort to generate reference genomes for European biodiversity, has reinforced the establishment of Biogenome Portugal. This nascent institutional network will connect the national community of researchers in genomics. Here, we describe the Portuguese contribution to ERGA’s pilot effort, which will generate high-quality reference genomes of six species from Portugal that are endemic, iconic and/or endangered, and include plants, insects and vertebrates (fish, birds and mammals) from mainland Portugal or the Azores islands. In addition, we outline the objectives of Biogenome Portugal, which aims to (i) promote scientific collaboration, (ii) contribute to advanced training, (iii) stimulate the participation of institutions and researchers based in Portugal in international biodiversity genomics initiatives, and (iv) contribute to the transfer of knowledge to stakeholders and engaging the public to preserve biodiversity. This initiative will strengthen biodiversity genomics research in Portugal and fuel the genomic inventory of Portuguese eukaryotic species. Such efforts will be critical to the conservation of the country’s rich biodiversity and will contribute to ERGA’s goal of generating reference genomes for European species.info:eu-repo/semantics/publishedVersio

    O paradoxo dos benzodiazepínicos: uma avaliação neurobiológica das consequências do uso e abuso na saúde física e mental

    Get PDF
    O uso indiscriminado de benzodiazepínicos tem sido objeto de preocupação devido suas consequências na saúde física e mental. Este artigo buscou avaliar neurobiologicamente os impactos dessas substâncias, conhecidas por modular a neurotransmissão gabaérgica, e confrontar as ideias centrais dos estudos disponíveis na atualidade. A ação dos benzodiazepínicos no sistema nervoso central promove efeitos ansiolíticos, sedativos, hipnóticos e relaxantes musculares, resultando em alívio imediato de sintomas como ansiedade e insônia. No entanto, o uso crônico dessas substâncias está associado a diversas consequências negativas. O comprometimento cognitivo é um dos principais impactos observados, incluindo déficits de memória e atenção. Além disso, o uso prolongado de benzodiazepínicos pode levar à queda da função hepática, aumentando o risco de lesões no fígado. O risco de quedas e fraturas também é elevado, principalmente em idosos, devido aos efeitos sedativos e relaxantes musculares dessas substâncias. O desenvolvimento de dependência e a síndrome de abstinência são preocupações adicionais, exigindo uma descontinuação gradual e monitoramento cuidadoso. Esta revisão de literatura abordou estudos que reforçam essas preocupações, destacando a importância de uma abordagem individualizada na prescrição de benzodiazepínicos. Profissionais de saúde devem considerar os riscos e benefícios, promovendo estratégias não farmacológicas para o manejo da ansiedade e insônia. No contexto brasileiro e mundial, é essencial conscientizar os pacientes sobre os potenciais riscos associados ao uso prolongado dessas substâncias. Alternativas terapêuticas estão sendo investigadas, visando minimizar os efeitos colaterais e oferecer opções mais seguras e eficazes. Em conclusão, o uso e abuso de benzodiazepínicos apresenta um paradoxo entre os benefícios terapêuticos imediatos e os riscos a longo prazo. Profissionais de saúde desempenham um papel fundamental na prescrição responsável dessas substâncias, garantindo o uso adequado e promovendo estratégias alternativas para o cuidado da saúde mental e física dos pacientes

    Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
