    The widespread use of Information and Communication Technologies - ICT substantially increases the risks related to information security. In fact, due to the increase in the number and type of cyber attacks, Cybersecurity has become a growing concern in today's society. This phenomenon affects not only individual citizens, but also companies and even State entities. Despite the numerous advantages of this "digitalisation" of society, there are several risks, ranging from identity theft, scam emails or phone calls, online fraud, offensive material and child pornography, material promoting racial hatred or religious extremism, access to online services, email account hacking, online banking fraud, cyber extortion or malicious software. In order to determine the impact that cyber attacks have on society it is necessary to understand how people and companies use ICTs, such as social networks, the information they share, their privacy concerns, or the use of electronic services such as online payments or the cloud. This study becomes central not only to try to prevent/minimise risks, showing what has been done in this area, but more importantly, the way forward to try to prevent or minimise possible risks in the future.info:eu-repo/semantics/publishedVersio

    Influential Factors for Hospital Management Maturity Models in a post-Covid-19 scenario - Systematic Literature Review

    The importance of Maturity Models in the health area was proven to support, monitor and direct health organizations to better plan and execute to their investments and developments. In this work, two reviews of the literature were collected: one of them focuses on identifying the main maturity models developed in the health area, the similarities, and gaps between them, identifying which are the Influencing Factors and, the other one, is to identify the lessons learned during the Covid-19 pandemic. In a pandemic scenario, the health sectors demonstrated the importance of the resilience, in which health systems had to adapt abruptly, considering physical structures; professional management; patient safety; supply chain and; technologies. Technologies, played an essential role to mitigating the pressure that health systems faced due to the increase in health costs, growth of chronic diseases, population aging, population’s expectation for more personalized health and, added to that, the confrontation of Covid-19 pandemic. In this sense, we identified the lack of maturity models that address the adversities that occurred during the Covid-19 pandemic in health systems for better hospital management and avoid the pressure to which they could be subjected again.info:eu-repo/semantics/publishedVersio

    Objective: to evaluate the level of physical activity, cardiorespiratory fitness and nutritional status of Brazilian higher education institution servers. Method: 134 public servants (80 men and 54 women) were evaluated to estimate body mass index (BMI), waist circumference (WC), waist/hip ratio (WHR), aerobic fitness and blood pressure at rest. Results: most of the servers were classified as insufficiently active (62%). BMI results show a high prevalence of obesity (39% mild and 33% moderate). WC showed a prevalence of high (30%) and very high risk (27%), and WHR showed a prevalence of high (28%) or very high risk (12%). The ergometric test showed that 41% of the servers presented very poor (17%) or poor (24%) aerobic fitness and 23%, regular aerobic fitness. Considering blood pressure, 15% of the servers presented blood pressure considered as borderline and 30% considered as hypertension. No associations were found between physical condition (active or inactive) with WC (χ2 = 3.4, p = 0.179), WHR (χ2 = 7.0, p = 0.073), aerobic fitness (χ2 = 4.3, p = 0.368) and blood pressure (χ2 = 2.9, p = 0.734). Although no association was observed between physical activity and BMI (χ2 = 7.6, p = 0.062), significance values (p < 0.07) suggested an association trend, with worse ratings for the sedentary group. Closing remarks: among higher education institution servers, there is high prevalence of physical inactivity, obesity and risk factors, and the majority of the sample had aerobic fitness below recommended levels

    Brominated flame retardants and natural organobrominated compounds in a vulnerable delphinid species along the Brazilian coast

    Guiana dolphins, Sotalia guianensis, are vulnerable to extinction along their distribution on the Brazilian coast and assessing chemical pollution is of utmost importance for their conservation. For this study, 51 carcasses of Guiana dolphins were sampled across the Brazilian coast to investigate legacy and emerging brominated flame retardants (BFRs) as well as the naturally-produced MeO-BDEs. PBDEs and MeO-BDEs were detected in all samples analyzed, whereas emerging BFRs were detected in 16 % of the samples, all in Rio de Janeiro state. PBDE concentrations varied between 2.24 and 799 ng.g-1 lipid weight (lw), emerging BFRs between 0.12 and 1.51 ng.g-1 lw and MeO-BDEs between 3.82 and 10,247 ng.g-1 lw. Concentrations of legacy and emerging BFRs and natural compounds varied considerably according to the sampling site and reflected both the local anthropogenic impact of the region and the diversity/mass of biosynthesizers. The PBDE concentrations are lower than what was found for delphinids in the Northern Hemisphere around the same sampling period and most sampling sites presented mean concentrations lower than the limits for endocrine disruption known to date for marine mammals of 460 ng.g-1 lw, except for sampled from Santa Catarina state, in Southern Brazil. Conversely, MeO-BDE concentrations are higher than those of the Northern Hemisphere, particularly close to the Abrolhos Bans and Royal Charlotte formation, that are hotspots for biodiversity. Despite the elevated concentrations reported for this group, there is not much information regarding the effects of such elevated concentrations for these marine mammals. The distinct patterns observed along the Brazilian coast show that organobrominated compounds can be used to identify the ecological segregation of delphinids and that conservation actions should be planned considering the local threats.A.F.
