Trata do processo de trabalho dos profissionais de saúde que atuam em uma unidade básica de saúde, em relação ao uso de tecnologias e à rede de relações que se estabelecem na produção do cuidado. Objetivos: Identificar as relações estabelecidas entre os prestadores de cuidado no espaço micropolítico de uma unidade básica; analisar os "ruídos" identificados no processo de trabalho dos profissionais. Método: Metodologia não-convencional, adaptada a um estudo qualitativo. Adotou-se um estudo de série de casos, cuja trajetória foi denominada trajetória-sentinela, e, através desta, foram detectados "ruídos" que influenciam na efetividade do cuidado. Conclusão: Foram identificados "ruídos" específicos, intra-institucionais e interpessoais. A análise destes revelou a fragilidade da rede de contratualidade estabelecida no interior dessa unidade, que está diretamente relacionada com o processo de trabalho e com a qualidade da assistência prestada.

Segmentation of masses in mammography images is an important task to aid the accurate diagnosis of breast cancer. Although the quality of segmentation is crucial to avoid misdiagnosis, the segmentation process is a challenging task even for specialists, due to the presence of ill-defined edges and low contrast images. One of the techniques of state of the art for tumor segmentation is the Fuzzy GrowCut algorithm. In this work a study is performed on the behavior of this algorithm when using different membership functions for segmentation. Moreover, this research proposes a new membership function, called Multi-Gaussian, which improves the results of Fuzzy GrowCut with respect to those obtained through the use of classical functions.

The rise of new technologies in the twenty-first century is accompanied by challenges in arts preservation that underscore the need to constantly adapt to new ways of approaching preservation issues. This article investigates the problems in preserving digitally-born cultural heritage and explores the connections between digital cultural heritage and preservation of digitally-born artwork. At the core of this study is the question of how to deal with and preserve digital cultural heritage in the changing world of technology, following a case study model with an emphasis on practical research. The results suggest that while the importance of preventing damage is crucial, further investigations are needed in order to fully treat issues concerning the accurate representation of the artist's intention.

ContextClimate and land-use changes are contributing to impacts on global ecosystems functioning. These effects are particularly severe in areas undergoing land abandonment and extreme wildfire events, such as the Mediterranean regions of Iberian Peninsula.ObjectivesPrevious studies have evaluated the impacts of land management on fire mitigation and biodiversity, but how such strategies influence functional diversity remains unexplored. This study investigates if alternative land-fire management strategies affect functional diversity.MethodsManagement scenarios were modelled for 2050 on the Transboundary Biosphere Reserve Gerês-Xurés (Portugal-Spain). The land-use scenarios simulated processes of land abandonment (“business-as-usual” – BAU) and the implementation of EU rural policies (“High Nature Value farmlands” - HNV), and were combined with three fire suppression levels. Species distribution models (102 vertebrates) were projected to each scenario and functional diversity indices were consequently calculated.ResultsThe highest functional richness was predicted for BAU scenarios, probably representing the benefits to unique species that deliver singular functions. The HNV scenarios provided the highest functional divergence, probably indicating a high niche differentiation and low resource competition amongst agricultural communities. HNV was the most beneficial scenario for ecosystem functioning, while fire suppression did not affect functional diversity.ConclusionsDespite the proneness to burn of our study area and the effects of firefighting on its fire regime, land-use policies are expected to overcome fire suppression effects on functional diversity. These findings suggest that different facets of functional diversity will be unevenly influenced by fire-landscape dynamics driven by the land-use policies to be implemented in the upcoming decades.
