Burnout prevalence in pediatricians of general hospitals
2008
OBJETIVO: Analizar la prevalencia del síndrome de quemarse por el trabajo (burnout) en pediatras de hospitales generales siguiendo criterios de diferentes países. MÉTODOS: Estudio transversal, no aleatorio, realizado en Buenos Aires, Argentina, en 2006. La muestra la formaron 123 pediatras que trabajaban en Servicios de Pediatría de hospitales generales, 89 fueron mujeres (72,4%) y 34 hombres (27,6%). Los datos fueron recogidos mediante un cuestionario anónimo y autoadministrado. El SQT fue diagnosticado utilizando el Maslach Burnout Inventory, con diferentes criterios para establecer su prevalencia. RESULTADOS: La prevalencia del SQT, varió en función del criterio utilizado: siguiendo los …
Impact of Electrical Stress and Neutron Irradiation on Reliability of Silicon Carbide Power MOSFET
2020
International audience; The combined effects of electrical stress and neutron irradiation of the last generation of commercial discrete silicon carbide power MOSFETs are studied. The single-event burnout (SEB) sensitivity during neutron irradiation is analyzed for unstressed and electrically stressed devices. For surviving devices, a comprehensive study of the breakdown voltage degradation is performed by coupling the electrical stress and irradiation effects. In addition, mutual influences between electrical stress and radiative constraints are investigated through TCAD modeling.
Impact of Terrestrial Neutrons on the Reliability of SiC VD-MOSFET Technologies
2021
Accelerated terrestrial neutron irradiations were performed on different commercial SiC power MOSFETs with planar, trench and double-trench architectures. The results were used to calculate the failure cross-sections and the failure in time (FIT) rates at sea level. Enhanced gate and drain leakage were observed in some devices which did not exhibit a destructive failure during the exposure. In particular, a different mechanism was observed for planar and trench gate MOSFETs, the first showing a partial gate rupture with a leakage path mostly between drain and gate, similar to what was previously observed with heavy-ions, while the second exhibiting a complete gate rupture. The observed fail…
Single-Event Burnout Mechanisms in SiC Power MOSFETs
2018
Heavy ion-induced single-event burnout (SEB) is investigated in high-voltage silicon carbide power MOSFETs. Experimental data for 1200-V SiC power MOSFETs show a significant decrease in SEB onset voltage for particle linear energy transfers greater than 10 MeV/cm 2 /mg, above which the SEB threshold voltage is nearly constant at half of the rated maximum operating voltage for these devices. TCAD simulations show a parasitic bipolar junction transistor turn-on mechanism, which drives the avalanching of carriers and leads to runaway drain current, resulting in SEB. peerReviewed
Isotopic Enriched and Natural SiC Junction Barrier Schottky Diodes Under Heavy Ion Irradiation
2022
The radiation tolerance of isotopic enriched and natural silicon carbide junction barrier Schottky diodes are compared under heavy ion irradiation. Both types of devices experience leakage current degradation as well as single-event burnout events. The results were comparable, although the data may indicate a marginally lower thresholds for the isotopic enriched devices at lower linear energy transfer (LET). Slightly higher reverse bias threshold values for leakage current degradation were also observed compared to previously published work.
Correlation between Work Engagement and Burnout among Registered Nurses: an Italian hospital survey
2019
AIM: To investigate the correlation between work engagement and burnout among Italian nurses. INTRODUCTION: Work engagement is a protective factor against burnout. Both of them may be affected by the cultural and organizational features of the investigated population, which means that results cannot be generalized. In Italy studies to measure how they correlate have never been performed. METHODS: Monocentric and quantitative observational study. The Maslach Burnout Inventory and the Utrecht Work Engagement Scale were used on a convenience sample of 318 nurses from an Italian hospital to assess the burnout and work engagement levels and to measure the existing correlation between the two con…
Psychometric properties of the Spanish Burnout Inventory among staff nurses
2015
Accessible summary The burnout syndrome contributes to the deterioration in the quality of personal life as well as lower quality practice in healthcare personnel. Researchers have been concerned about the psychometric limitations of some previous questionnaires designed to evaluate burnout. The Spanish Burnout Inventory was developed to address the problems associated with other instruments, but it has not yet been validated in staff nurses. This study provides evidence that the Spanish Burnout Inventory has adequate psychometric properties to estimate burnout in staff nurses. The Spanish Burnout Inventory offers a theoretical proposal to explain the different components of burnout. The Sp…
Social Suffering and an Approach to Professionals’ Burnout
2014
Individual and social problems require the assistance of professionals who are accustomed to work with “suffering” on daily basis. Psychologists, physicians, and social workers step into this role helping alleviate the suffering and improve the quality of life of their patients and clients. But, inevitably, they experience suffering as they address others’ problems. Their own well-being and quality of life may be reduced by their work in helping. We interviewed Argentinean professionals about their experience of patient, personal, and suffering conditions in order to determine the level of transference and turn to the practice of Yoga as a possible physical and psychological approach to med…
Utilidad de los marcadores biológicos en la detección precoz y prevención del síndrome de burnout [Usefulness of biological markers in early detectio…
2014
Usefulness of biological markers in early detection and prevention of burnout syndrome Abstract: Burnout is associated with a worse health self-perception and greater physical and psychiatric comorbidity. The objective of this review is to summarize in a systematic way the main biomarkers associated with the burnout syndrome: cardiovascular (blood pressure, heart rate and variability of heart rate); sleep-related (quality, fragmentation, and sleep latency); associated with the hypothalamic-pituitary-adrenal axis and the sympathetic-adrenal-medullary axis (cortisol, sa- livary IgA, lysozime, α-amylase and chromogranin-A); related to the immune system (natural killer cells and mononuclear ant…
Impact of burn-out syndrome in oncology personnel and its improvement through specific interventions
2019
Abstract Background Burn-Out Syndrome (BOS) in oncology nurses, has few experiences reported about its incidence and impact in its three different areas: emotional and physical exhaustion, cynism and despersonalization and no personal nor profesional fulfillment. There is a lack of resources for its diagnosis and management, although it impacts negatively in the patient attention/ care quality and the quality of institutional processes, added the personal impact in personal workers lives. Our objective was to determine the incidence of the BOS in our workers, analyze its causes and reduce in 20% the percentage of workers suffering or at risk of suffering BOS. Methods 23 nurses / nurse assis…
