A qualitative study about immigrant workers’ perceptions of their working conditions in Spain
2009
Background: Spain has recently become an inward migration country. Little is known about the occupational health of immigrant workers. This study aimed to explore the perceptions that immigrant workers in Spain had of their working conditions. Methods: Qualitative, exploratory, descriptive study. Criterion sampling. Data collected between September 2006 and May 2007 through semi-structured focus groups and individual interviews, with a topic guide. One hundred and fifty-eight immigrant workers (90 men/68 women) from Colombia (n = 21), Morocco (n = 39), sub-Saharan Africa (n = 29), Romania (n = 44) and Ecuador (n = 25), who were authorised (documented) or unauthorised (undocumented) resident…
The safety attitudes questionnaire for out-of-hours service in primary healthcare—Psychometric properties of the Croatian version
2020
The aim of the study was to assess the reliability and construct validity of the Croatian trans- lation of the Safety Attitudes Questionnaire—Ambulatory version (SAQ-AV) in the out-of- hours (OOH) primary care setting. A cross-sectional observational study using anonymous web-survey was carried out targeting a convenience sample of 358 health professionals working in the Croatian OOH primary care service. The final sample consisted of 185 questionnaires (response rate 51.7%). Psychometric properties were assessed using exploratory hierarchical factor analysis with Schmid-Leiman rotation to bifactor solution, McDonald’s ω, and Cronbach’s α. Five group factors were identified: Organization cl…
Consolidation of working hours and work-life balance in anaesthesiologists - A cross-sectional national survey.
2018
Currently, healthcare management fosters a maximization of performance despite a relative shortage of specialists. We evaluated anaesthesiologists' workload, physical health, emotional well-being, job satisfaction and working conditions under increased pressure from consolidated working hours. A nationwide cross-sectional survey was performed in Austrian anaesthesiologists (overall response rate 41.0%). Three hundred and ninety four anaesthesiologists (280 specialists, 114 anaesthesiology trainees) participated. Anaesthesiologists reported frequently working under time pressure (95%CI: 65.6-74.6), at high working speed (95%CI: 57.6-67.1), with delayed or cancelled breaks (95%CI: 54.5-64.1),…
Evaluation of occupational physical load during 6-month international crisis management operation
2018
Objectives Generally, operational military duties are associated with a variety of stressors, such as prolonged physical activity (PA). However, limited information is available on the occupational workload or changes in PA during international military operations. Thus, the aim of the study was to investigate the changes in body composition, stress biomarkers, PA, and heart rate (HR) responses of 79 male soldiers during a 6-month international crisis management operation. Material and Methods Measurements were conducted 3 times in South-Lebanon during the operation. Body composition was assessed by the bioelectrical impedance method. Blood samples were analyzed for serum testosterone, sex-…
Burnout in Cardiac Anesthesiologists: Results From a National Survey in Italy
2018
Objective There is increasing burnout incidence among medical disciplines, and physicians working in emergency settings seem at higher risk. Cardiac anesthesiology is a stressful anesthesiology subspecialty dealing with high-risk patients. The authors hypothesized a high risk of burnout in cardiac anesthesiologists. Design National survey conducted on burnout. Setting Italian cardiac centers. Participants Cardiac anesthesiologists. Interventions The authors administered via email an anonymous questionnaire divided into 3 parts. The first 2 parts evaluated workload and private life. The third part consisted of the Maslach Burnout Inventory test with its 3 constituents: high emotional exhaust…
Estimating brain load from the EEG.
2009
Modern work requires cognitively demanding multitasking and the need for sustained vigilance, which may result in work-related stress and may increase the possibility of human error. Objective methods for estimating cognitive overload and mental fatigue of the brain on-line, during work performance, are needed. We present a two-channel electroencephalography (EEG)–based index, theta Fz/alpha Pz ratio, potentially implementable into a compact wearable device. The index reacts to both acute external and cumulative internal load. The index increased with the number of tasks to be performed concurrently (p= 0.004) and with increased time awake, both after normal sleep (p= 0.002) and sleep restr…
Comparison of low-frequency electrical myostimulation and conventional aerobic exercise training in patients with chronic heart failure.
2005
Physical training is recommended as an efficient therapy in patients with chronic heart failure (CHF). Low-frequency electrical myostimulation (EMS) has recently been suggested as a good alternative to conventional aerobic training. The aim of this study was to compare the effects of EMS and conventional exercise training in patients with moderate to severe CHF.Twenty-four patients with stable CHF (56.7+/-7.3 years, New York Heart Association grades II and III) underwent 5 weeks of exercise training, 5 h a week, using EMS (n=12) or conventional (n=12) training programmes. At baseline and after the training period, patients performed a symptom-limited cardiopulmonary test, a 6-min and a 200-…
Physical heaviness of work and sitting at work as predictors of mortality : a 26-year follow-up of the Helsinki Birth Cohort Study
2019
ObjectivesTo examine the relationships of late-career physical heaviness of work and sitting at work with mortality. A national-level job exposure matrix was used to determine the occupation-specific level of physical heaviness and sitting.DesignProspective cohort study between years 1990 and 2015.SettingCommunity.Participants5210 men and 4725 women from the Helsinki Birth Cohort Study with an occupational code at baseline (ages 45–57 years).Primary and secondary outcome measuresTotal, cardiovascular (International Classification of Diseases 10th Revision I00–I99), cancer (C00–C97) and external (S00–Y84) mortality.ResultsThe exposures, physical heaviness and sitting had a non-linear, invers…
Tabu search algorithms for an industrial multi-product and multi-objective assembly line balancing problem, with reduction of the task dispersion
2002
This paper presents a real-world industrial application of the multi-product and multi-objective assembly line balancing problem, for a company involved in the production of four models of a white goods product. The problem solved is a GALBP-2, with 10 workstations and multiple objectives (to maximize the production rate in order to deal with an increase of the demand forecasted, to reach an equal cycle time of all the models and an equal workload of the different workstations, and finally, to minimize the dispersion of worker tasks on each one of the different models-the common tasks of the different models at the same workstation). The paper presents an integrated approach based on four h…
Effects of the cycling workload on core and local skin temperatures
2016
[EN] Purpose: The aim of the study was to determine the influence of cycling workload on the variation of core and skin temperature of the different body regions, and the relationship between both temperature variables. Method: Fourteen cyclists performed two 45-min cycling tests at 35% and 50% of peak power output on different days. The cadence was constant in both tests (90 rpm). Core temperature was measured continuously throughout the test and local skin temperature was recorded before, immediately after and 10 min after finishing the cycling test. Differences in variation of the core and skin temperature and in the effort perception and body mass loss due to different cycling workload …
