ABSTRACT BACKGROUND: Burnout is a syndrome that mostly affects professionals working in contact with patients and their caregivers. In oncology care, nursing professionals are constantly required to provide emotional support for patients and their caregivers, throughout the process of becoming ill, suffering and dying. OBJECTIVE: To evaluate the prevalence and factors associated with burnout in a sample of nursing professionals at a cancer hospital. DESIGN AND SETTING: Cross-sectional study conducted at Hospital de Câncer de Barretos. METHODS: The study population comprised 655 nursing professionals. Burnout syndrome was assessed using the Maslach Burnout Inventory Human Service Survey. Univariate analysis and binary logistic regression models were used to identify independent predictors associated with burnout. RESULTS: Among 304 nursing professionals included in the study, 27 (8.9%) were classified as presenting burnout according to the two-dimensional criteria, and four (1.3%) were classified based on the three-dimensional criteria. Workplace characteristics were not associated with burnout, while single marital status (odds ratio, OR = 2.695; P = 0.037), perceived workplace stressors, such as impatience with colleagues (OR = 3.996; P = 0.007) and melancholy (OR = 2.840; P = 0.021) were considered to be predictors of burnout. Nursing professionals who would choose the profession again (OR = 0.214; P = 0.001) were least likely to present burnout. CONCLUSION: Perceived workplace stressors are strongly associated with burnout. Strategies focusing on restructuring of daily work processes and on activities that stimulate positive relationships are important for professionals’ health because motivation to continue working in oncology nursing has a protective effect against burnout.

ABSTRACT The characterization of steel fiber reinforced concrete with dry consistency require greater inspection the account of the particularities in the process of mixing, molding and densification, thus this paper aims to propose a methodology combined of densification by manual and mechanical means and the mechanical characterization by the three-point flexural testin prismatic dry cast steel fiber-reinforced concrete specimen. In a qualitative way, the densification-combined methodology provided a smooth surface on the specimen appearance and a reduction of voids due to trapped air. In the flexural test we verified slip-softening and slip-hardening, respectively, to lower and higher reinforcement indexes and theoretical volumes. By the analysis of variance of the results and the database we found out that there was no significant statistical difference to the analyzed residual strength for the combination of the test method (RILEM), consistency (plastic), type (hooked end) and form (glued), when the comparison is made by quadruple association.

RESUMEN La caracterización del concreto de consistencia seca con fibras de acero requiere mayores investigaciones por cuenta de las particularidades en el proceso de mezcla, moldeado y adensamiento, por lo tanto, el objetivo de este trabajo es proponer una metodología combinada para la densificación manual y mecánica y la caracterización mecánica con ensayo de tracción en una flexión en tres puntos en de cuerpos de prueba prismáticos de concreto de concreto de consistencia seca con fibras de acero. De modo cualitativo una metodología combinada de densificación proporcionó un aspecto liso a la superficie en el cuerpo de prueba y reducción de los vacíos por el aire aprisionado. En el ensayo de tracción una flexión verificó el comportamiento de slip-softening y slip-hardening, respectivamente, para menores y mayores índices de refuerzo y volúmenes teóricos. Al final se constató que el análisis de varianza del banco de datos indicó mayores valores de resistencia residual para la combinación del método de ensayo (RILEM), consistencia (plástica), especie (hookedend) y camino (colado en peine), cuando se hace la comparación por asociación cuádruple.
