Este artigo problematiza o sigilo profissional em uma perspectiva ética com o objetivo de apresentar a sua caracterização e complexidade a partir de alguns elementos contemporâneos presentes na sociedade brasileira, como o domínio midiático sobre a vida privada da população pobre, as exigências postas ao assistente social na relação direito e dever no contexto institucional e legal, assim como as perguntas que sinalizam sua pertença ao campo ético.
Coordination Of Maritime assets for Persistent And Systematic Surveillance (COMPASS2020) is an EU H2020 project, which has as an overarching goal deployment of Unmanned Vehicles (UxV) - aerial, sea surface and underwater ones, in addition to manned offshore patrol vessels, to enhance current maritime border surveillance operations regarding detection of irregular migrants and narcotics smugglers. This paper gives an overview of several research projects on autonomous marine vehicles, as a key technological, organizational and legislative issue within the project scope: Kaisa, an autonomous vessel prototype built at SAMK Faculty of Logistics and Maritime Technology in Rauma (Finland). Autonomous Ships 101 from Solent University in Southampton (England). A review of other articles has served as a comparative analysis to the surveillance assets proposed by COMPASS2020
Over the last few years, much online volunteered geographic information (VGI) has emerged and has been increasingly analyzed to understand places and cities, as well as human mobility and activity. However, there are concerns about the quality and usability of such VGI. In this study, we demonstrate a complete process that comprises the collection, unification, classification and validation of a type of VGI—online point-of-interest (POI) data—and develop methods to utilize such POI data to estimate disaggregated land use (i.e., employment size by category) at a very high spatial resolution (census block level) using part of the Boston metropolitan area as an example. With recent advances in activity-based land use, transportation, and environment (LUTE) models, such disaggregated land use data become important to allow LUTE models to analyze and simulate a person's choices of work location and activity destinations and to understand policy impacts on future cities. These data can also be used as alternatives to explore economic activities at the local level, especially as government-published census-based disaggregated employment data have become less available in the recent decade. Our new approach provides opportunities for cities to estimate land use at high resolution with low cost by utilizing VGI while ensuring its quality with a certain accuracy threshold. The automatic classification of POI can also be utilized for other types of analyses on cities. ; Singapore-MIT Alliance for Research and Technology (Singapore.

Objectives: This study aimed to examine the relationship between age, body mass index, muscle strength, and balance in physically active, aged adults. Methods: Eighty-five participants were recruited for this study, having an average age of 70.31 years (SD = 9.90), ranging from 50 to 92 years. Twenty-six (30.6%) participants were male and fifty-nine (69.4%) were female. The participants had an average body mass index of 27.30 kg/m2 (SD = 3.62), ranging from 20.32 to 38.58 kg/m2. Participants undertook the Timed-Up and Go to test balance, and the chair-stand test to assess lower body strength. Hierarchical regression analyses were conducted. Three models (Model 1, 2, and 3) were tested to assess their relationships with balance: M1—Lower body muscle strength; M2—Lower body muscle strength and body mass index; M3—Lower body muscle strength, body mass index, and age. Results: All hierarchical models displayed significant variance. The third model explained 50.9% of the variance in dynamic balance, [F(3, 81) = 27.94, p < 0.001, R = 0.71, Ra2 = 0.51]. The difference in Ra2 between the first, second, and third models was statistically significant (p < 0.05). Age, body mass index, and lower body muscle strength had significant (p < 0.05) correlations with balance. In terms of the significant impact of each predictor, age had the strongest association with balance (p < 0.05). Conclusions: The results are useful to understand mechanisms or diagnose people at risk of fall.
The growing concern to promote sustainable agriculture, seeking environmental preservation and, at the same time, increased productivity resulted in the search for technologies for the implementation of agricultural production systems, with ecological approaches and responsible use of natural resources, in the economic, political and social contexts in each region. One of the potential alternatives to achieve these results would be the use of humic substances, considering their direct and indirect mechanisms aimed at increasing agricultural production. Thus, the objective of this work was to evaluate the bioactivity of humic and fulvic acids, as well as to promote improvements in the phytotechnical attributes of banana cv. Prata-Anã micropropagated. The treatments consisted of five doses of humic acid and fulvic acid (2; 5; 10; 20 and 40 mg L-1) and a control without humic substances. Higher values for the length of the aerial part and the larger root were obtained with the use of 40 mg L-1 fulvic acid. The results prove the ability of fulvic acid to improve the in vitro development of banana explants. ; La creciente preocupación por promover la agricultura sostenible, buscando la preservación del medio ambiente y, al mismo tiempo, el aumento de la productividad derivó en la búsqueda de tecnologías para la implementación de sistemas de producción agrícola, con enfoques ecológicos y uso responsable de los recursos naturales, en el ámbito económico, político y contextos sociales en cada región. Una de las posibles alternativas para lograr estos resultados sería el uso de sustancias húmicas, considerando sus mecanismos directos e indirectos dirigidos a incrementar la producción agrícola. Así, el objetivo de este trabajo fue evaluar la bioactividad de los ácidos húmicos y fúlvicos, así como promover mejoras en los atributos fitotécnicos del banano cv. Prata-Anã micropropagado. Los tratamientos consistieron en cinco dosis de ácido húmico y ácido fúlvico (2; 5; 10; 20 y 40 mg L-1) y un control sin sustancias húmicas. Se obtuvieron valores más altos para el largo de la parte aérea y la raíz más grande con el uso de 40 mg L-1 de ácido fúlvico. Los resultados demuestran la capacidad del ácido fúlvico para mejorar el desarrollo in vitro de explantes de plátamo. ; A crescente preocupação em promover uma agricultura sustentável, buscando a preservação do meio ambiente e, ao mesmo tempo, o aumento da produtividade resultou na busca por tecnologias para a implantação de sistemas de produção agrícola, com abordagens ecológicas e uso responsável dos recursos naturais, nos âmbitos econômico, político e contextos sociais em cada região.
