Background: Mental workload is one of the factors that influence individuals’ performance in the work environment as well as their efficiency and productivity. This study aimed to evaluate the effectiveness of the Rating Scale Mental Effort (RSME) for mental workload in nurses. Materials and Methods: This study was descriptive and cross-sectional conducted on 75 nurses. For assessment ...

 Background and Purpose: Currently, the high prevalence of COVID-19 and increased workload in hospitals has posed a threat to the physical, mental, and emotional health of nurses. The present study was an attempt to investigate the workload and its relationship with job stress of nurses in COVID-19 reference hospitals in southern Iran. Methods: This descriptive-analytical and cross-sectional s...

The purpose of this paper is to identify the variables for integrated cost and schedule control in terms of reducing required workload. Potential variables including project delivery system, contract type, level of outsourcing, degree of specialization, progress measurement methods, budget format, management detail, vertical integration, and so on are identified first. The variables are then re...

Web cache servers (proxies) are increasingly popular for reducing Internet traac and improving response time. The disk subsystem appears to be a bottleneck in such servers. We present techniques for improving disk performance of Web proxies and evaluate them with simulation. The disk workload of proxies has a signiicant volume of new le writes. We show that directing writes to less loaded disks...

Machine is the key element in manufacturing system. failure will lead to order delivery delay and production cost rise. Aiming at random disturbance of equipment failure, a dynamic non-linear programming model virtual cell (VMC) established, which aims minimize cost, logistics transportation differences workload among cells, based on comprehensive consideration reliability, process route constr...

OBJECTIVE Two experiments are presented examining adaptive and adaptable methods for invoking automation. BACKGROUND Empirical investigations of adaptive automation have focused on methods used to invoke automation or on automation-related performance implications. However, no research has addressed whether performance benefits associated with brain-based systems exceed those in which users h...

There is considerable evidence in the ergonomics literature that automation can significantly reduce operator mental workload. Furthermore, reducing mental workload is not necessarily a good thing, particularly in cases where the level is already manageable. This raises the issue of mental underload, which can be at least as detrimental to performance as overload. However, although it is widely...

The goal of this study was to demonstrate a measurable correlation between facial temperature changes and the human learning process. This study also introduces a method for determining sufficient training time by monitoring the cognitive load of the learner as indicated by changes in facial temperature. A non-invasive method using an infrared camera was employed to detect nose temperature chan...
