 | Previous research conducted by DRDC-Toronto to evaluate watch schedule variants used on Royal Canadian Navy (RCN) submarines indicated very significant and deleterious effects of the watch system on modeled cognitive effectiveness of RCN submariners. Subsequently, DRDC-Toronto hosted an International Submarine Watch Schedule Symposium which led to a new RCN submarine watch schedule that improved modeled performance by about 30%. The RCN surface fleet is aware of this work and supported ... |

| Both the public sector and the military are working on developing drowsiness detection systems, as driver fatigue is a significant contributor to motor vehicle accidents. Individually, electroencephalography (EEG) and eye-tracking measures are tenuous indicators of driver fatigue and impairment. This project proposes to integrate multiple sensor modalities in order to improve drowsiness level assessment and driver performance prediction. There is substantial evidence supporting the correlation of alpha bursts in EEG ... |

| Exertional and/or environmental heat stroke (ES) and exertional rhabdomyolysis (ER) has been reported in patients with diagnosis of Malignant Hyperthermia (MH). MH is a life-threatening pharmacogenetic disorder caused by mutations in the ryanodine receptor type 1 gene (RYR1) encoding skeletal muscle calcium release channel. Our goal is to identify RYR1 mutations associated with enhanced susceptibility to EHS/ER/MH by enrolling subjects diagnosed with these conditions and performing genetic screening. We also ... |

| Fatigue continues to pose a serious threat to the health, safety, and operational effectiveness of military aircrew. Recent efforts to mitigate the effects of fatigue have focused on the identification of individualized readiness-to-fly screening measures. Eye-tracking measures, such as saccadic velocity in a simple visual tracking task, have shown promise in the laboratory setting for their ability to detect and quantify fatigue-related performance decrements in a military aviation population subjected ... |

| In recent years optimal manning has been implemented on U.S. Navy surface ships where crew sizes have been reduced. This undermanning has resulted in a requirement for sailors to stand longer watches and get less sleep, making for less effective sailors while standing watch. Alternative watch schedules can be used that minimize fatigue of sailors while on watch. The first objective of this study is to analyze a USS San ... |

| There is a growing population of employees that work non-traditional hours in around-the-clock operations. Cabin crew/flight attendants are part of this population and work highly variable schedules that include extended duty days, time zone changes, night schedules, and on-demand calls. These schedules conflict with the body's natural mechanisms for managing sleep and alertness, and often result in fatigue. Fatigue countermeasure training may be necessary for the health, well-being, and safety ... |

| Today's aviation industry is a 24/7 operation that produces a variety of challenges for cabin crew members, including extended duty periods, limited time off, frequent time zone changes, jet lag, less-than-optimal sleeping conditions, and nonstandard work hours such as night duty and rotating schedules. Despite operational requirements, the body's biological need for sleep does not change. In other words, individuals are not physiologically prepared to operate effectively on the 24/7 ... |

| The unregulated hours and frequent night work characteristic of maintenance can produce significant levels of employee fatigue, with a resultant risk of maintenance error. Fatigue Risk Management Systems (FRMS) are widely used to manage fatigue among flight crew and drivers of commercial vehicles, but comprehensive approaches to fatigue risk management are still uncommon within maintenance organizations. In the wider transport industry, the objective of most FRMS has been to reduce ... |

| People often fail to execute even a well-learned skill under stress and fatigue (e.g., time pressure). What are the necessary shortfalls in the cognitive mechanisms that govern this failure? To examine this failure, we consider that formalized modeling is one of the most logical and reasonable of all methods to help us refine and advance our understanding of real-world operational effects. Models force us to make our assumptions explicit and ... |

| Standing and marching have been associated with musculoskeletal pain of the feet as well as discomfort and fatigue of the back and lower extremities. U.S. Army Band members spend hundreds of hours a year standing and marching. To see if musculoskeletal pain could be reduced, one pair of viscoelastic silicone insoles were provided to band members (n=69).

| We have been developing a computational theory of the effects of fatigue (especially sleep-related fluctuations in alertness) on the human cognitive system, implemented through mechanisms that impact existing components of the ACT-R architecture. These mechanisms include the suppression of activation in the declarative knowledge system, as well as brief breakdowns in the central production execution cycle, which we call micro-lapses. Through an iterative series of mechanistic architectural modifications, model implementations, ... |

| Human performance technologies include among others the use of psycho-active pharmaceuticals. In trying to answer the question if the use of psycho-active pharmaceuticals in the military is ethically acceptable, a psycho-medical model with four guiding questions is discussed. From two examples of modern warfare with these guiding questions, it is concluded that an ethical use of psycho-active pharmaceuticals is possible. Also three additional points of view are discussed.

| The effect of stress and exposure to anti-cholinesterases on the cholinergic system were tested in vitro and in vivo. Rapid muscle fatigue was identified and electrophysiologically characterized in mice with elevated levels of AChE-S, the synaptic variant of acetylcholinesterase (AChE). Anxiety responses were observed in mice that over-expressed the stress-associated variant, AChE-R. The binding partner of AChE-R in mouse neurons was identified as a component of the protein kinase-C signaling ... |

| An overview of total sleep deprivation is offered that attempts to sample the broad array of studies conducted in the area. A distinction is made between sleepiness and fatigue as explanations for the behavioural effects attributed to sleep loss. The first, sleepiness, concerns itself with the pressure to fall asleep that is moderated by circadian pressures, while the second, fatigue, addresses a hypothesized monotonic (more or less) degradation in capability ... |
