Analysis of Well-Being and Anxiety among University Students.

This article aims to interrelate dimensions of the well-being validation instruments proposed by Watson, Clark and Tellegen (PANAS) with generalized anxiety dimensions proposed by Spitzer et al. (GAD-7) and state-trait anxiety inventories proposed by Biaggio and Natalício (IDATE), using partial least squares structural equation modeling (PLS-SEM), in the case of individual university students in southern Brazil and the city of Buenos Aires, Argentina. We conducted a behavioral study, characterized as exploratory-descriptive, by applying a questionnaire survey to collect data though face-to face interviews to a group of 460 university students from June to August 2019.

The framework of the practice of innovation in primary healthcare: a case study.

The objective of this study was to identify the practice of innovation in primary healthcare in the second-largest county, by population, in the state of Rio Grande do Sul, Brazil. The methodology employed case studies of multiple units of analysis, where various studies were simultaneously conducted. Forty-five semi-structured interviews were carried out with the directors of basic health clinics, followed by content analysis, beginning with the construction of a system of categories based on the literature.

Glutaraldehyde degradation in hospital wastewater by photoozonation.

In this paper, we assessed aqueous solutions of glutaraldehyde (GA), a chemical used for the disinfection of hospital materials, using advanced oxidative processes, O3, and UV, and the combination of the latter two. Assays with different ozone concentrations at distinct pH levels were conducted to determine the best treatment process. GA concentrations before and after each treatment were measured by spectrophotometry.
