Mental workload is an important component in complex human-machine systems. The limited applicability of empirical workload measures produces the need for workload modeling and prediction methods. In the present study, a mental workload prediction model is built on the basis of attentional resource allocation and information processing to ensure pilots' accuracy and speed in understanding large...
background: few studies have examined the relationship between perceived responsibilities by workers and job characteristics and experiences of stress. objective: to examine the relationship between job stress and work responsibilities and job characteristics. methods: we analyzed data from 2737 adults who were labor force participants in the province of alberta, canada. a logistic regression m...
Introduction: Control room is one of the most important working environments that require optimal performance of individuals to minimize errors. Lighting is one of the environmental factors affecting the operation of the control room operators. Providing optimal lighting in the control room is very important. The purpose of this study was to determine the effect of light on workload, sleepiness...
Two basic approaches are taken when modeling workloads in simulation-based performance evaluation of parallel job scheduling algorithms: (1) a carefully reconstructed trace from a real supercomputer can provide a very realistic job stream, or (2) a exible synthetic model that attempts to capture the behavior of observed workloads can be devised. Both approaches require that accurate statistical...
methods this cross-sectional study was conducted on 293 nurses working in 24 wards of baqiyatallah hospital in tehran, iran, in 2016. the sampling method was stratified random sampling. data were collected using a self-administered questionnaire, which was classified into 4 subtitles: individual and organizational characteristics, perceived subjective, objective workloads, and some patient safe...
conclusions the results showed that the heat stress increased by increasing air velocity and humidity in both groups. the air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity i...
Introduction: High mental workload is one of the important factors that results in errors in safety and occupational health scope and its measurement has high importance. So, this study aimed to determine validity and reliability of Verbal Online Subjective Opinion (VOSO) and Modified Cooper-Harper (MCH) scales in measuring mental workload. Methods: This study was conducted on 90 male studen...
Introduction: One of the factors influencing the behavior and performance of nurses at the workplace is the mental workload. It is the amount of mental effort that a person uses during doing his or her task. Objective: The current study aimed at evaluating the mental workload and its related factors in the Intensive Care Unit (ICU) affiliated to medical and educational centers of Guilan Univer...
Background: The employees of welfare centers, due to the special conditions of their work, may be exposed to excessive occupational stress and workload . Thus, the aim of this study was to determine the effect of workload and occupational stress on the general health of female employees of public welfare centers. Materials and Methods: This was a correlational research on 63 fe...
