RESUMO

PURPOSE OF REVIEW: This article aims to discuss the current state of resources enabling the democratization of artificial intelligence (AI) in ophthalmology. RECENT FINDINGS: Open datasets, efficient labeling techniques, code-free automated machine learning (AutoML) and cloud-based platforms for deployment are resources that enable clinicians with scarce resources to drive their own AI projects. SUMMARY: Clinicians are the use-case experts who are best suited to drive AI projects tackling patient-relevant outcome measures. Taken together, open datasets, efficient labeling techniques, code-free AutoML and cloud platforms break the barriers for clinician-driven AI. As AI becomes increasingly democratized through such tools, clinicians and patients stand to benefit greatly.

RESUMO

The hydrothermal synthesis of nano-faujasite has been successfully performed and the effects of some crystallization parameters were investigated, along with the use of this material as a heavy-metal ion adsorbent. X-ray diffraction patterns have shown that the structure of the nano-faujasite is strongly dependent on both the crystallization time and the alkalinity of the synthesis medium. According to N2 physisorption, X-ray fluorescence, SEM/EDS, and solid state 29Si and 27Al NMR data, the produced nano-faujasite consists of a solid with low molar Si/Al ratio (1.7), with high availability of ion exchange sites and high surface area/small particle size, allowing easy diffusion of metal ions to adsorbent active sites. As a consequence, an excellent performance on removal of Cd2+, Zn2+ and Cu2+ ions was found for this solid. The adsorption capacity followed the order Cd2+ (133 mg·g-1) > Zn2+ (115 mg·g-1) > Cu2+ (99 mg·g-1), which agrees with the order of increasing absolute values of the hydration energy of the metal ions. Kinetic studies and adsorption isotherms showed that the metal ion removal takes place by ion exchange on the monolayer surface of the nano-faujasite. The electrochemical recovery of copper in metallic form exhibited an efficiency of 80.2% after 120 min, which suggests that this process can be adequately implemented for full-scale metal removal.

RESUMO

The aims of this study were to evaluate aging factors associated with work stressors, work ability, and the quality of living conditions, among health care personnel. A cross-sectional study was conducted among 176 health care shiftworkers. Two health survey questionnaires (Tuomi et al., 1997, Scandinavian Journal of Work, Environment and Health, 17(Suppl 1), 67-74; and Tepas, 1996, unpublished instrument) were completed and ergonomic work analyses (Rohmert & Landau, 1983, A new technique for job analysis, London and New York: Taylor & Francis) were carried out at the emergency wards. Main concerns about exposure at the workplace were changes in equipment and technology, transportation, and changes in employer policies. Main concerns about off-the-job conditions were personal safety, increases in the cost of living, food safety, and water and air quality. 81.7% scored adequate (> 36.5 points) in the Work Ability Index, and considered themselves having adequate current work ability to cope with physical, mental, and social demands. The most frequently reported diseases were musculoskeletal disorders and minor emotional problems.
