night work can have a significant impact on health, well-being, performance and occupational safety of workers. night workers often complain about the sleep disorder characterized by excessive sleepiness.  the aim of the study was to determine the level of sleepiness among night workers and investigate its relationship with oral temperature in a hot industry. this cross-sectional study involved...

Civil aviation operators have expressed an increased interest in conducting night operations with night vision imaging systems. The development of special operational concepts, hardware requirements, training requirements, and regulatory change and oversight is necessary to control for the known performance constraints associated with these devices. In 2001, the Aerospace Medical Association in...

Two experiments were carried out to examine the effect of interruption position and interruption duration on postcompletion error (PCE) occurrences in a game-like procedural task. Experiment 1 showed a significant main effect of interruption position on PCE rate; significantly more PCEs were obtained when the interruption occurred just before the PC step than interruptions at any other position...

User’s cognitive state is extremely fragile and sensitive to external interruption, especially when a user is performing a cognitively-taxing task. Given that interruptions frequently occur during human-computer interaction, and given the relative scarcity of human attention and their vulnerability to interruptions, interruption-resistance is needed to be considered when designing user interfac...

We examine people’s strategic cognitive responses to being interrupted while performing a task. Based on memory theory, we propose that resumption of a task after interruption is facilitated by preparation during the interruption lag, or the interval between an alert to a pending interruption (e.g. the phone ringing) and the interruption proper (the ensuing conversation). To test this proposal,...

this paper analyzes a renewal input  working vacations queue with change over times and bernoulli schedulevacation interruption under (a,c,b) policy.the service and vacation times are exponentially distributed.the server begins service if there are at least c units in the queue and the service takes place in batches with a minimum of size a and a maximum of size b (a

Abstract Introduction Nocturia (waking from sleep to urinate) is the most common cause of interruption among older adults and nocturnal polyuria (NP; increased time urine production) its cause. Conversely, poor with repeated awakenings contributes both nocturia NP. However, whether a behavioral intervention reduce can improve NP has not been examined in clinical trial. The current study assesse...

Introduction Interruption of enteral nutrition (EN) is common in the intensive care unit (ICU). Frequent episodes of EN interruption can lead to protein and calorie debt with a potential impact on outcomes in critically ill patients [1,2]. However, few studies have investigated the details of EN interruption practice including the reasons and duration of the interruption [3,4]. A standard proto...

background: the presence of small intestine in the radiation field during pelvic cancers treatment causes an interruption in radiotherapy. a non-invasive method was developed to exclude small intestine during conventional radiotherapy. materials and methods: the incidence of the radiation therapy interruption is highly dependent upon the area of the small intestine included in the portals and i...
