Human Error: The Three Types Of Fatigue

— Today Driver Fatigue is one of the most common reasons for fatal road accidents around the world. This shows that in the transportation industry especially, where a driver of a heavy vehicle is often exposed to hours of continuous driving which causes fatigue without frequent rest period. Thus, driver drowsiness detection has been considered a major potential area so as to prevent a huge number of sleep induced road accidents. This paper proposes a various head pose estimation methods to detect driver drowsiness. Whereas many of the researches are focused on the drivers face, this approach focuses on the drivers head movement. By collecting the drivers head position and extracting the feature points, the proposed system calculates the driver’s

This change in body temperature has a great influence of human alertness and mental performance at work, with lowest performance experienced between 0300hrs – 0600hrs in the morning. It is therefore vital that work schedule and planning should consider these changes in performance and adjust accordingly.

Driver fatigue is a common occurrence for those who are driving long distances or driving at times of the day or night when they should naturally be sleeping. Becoming overtired when behind the wheel is dangerous and unfortunately highly common in a time where daily activities continue to move along, despite our need to rest.

There are barriers to CRF occurring at the patient, professional and system levels. The patients barrier is due to the patient believing that their fatigue is not important, that it is inevitable or untreatable. Patients usually do not consider fatigue as a valid problem to complain about to their providers. Even when patients communicate an overwhelming or severe fatigue, they are not sure about the process that care health care providers will use to diagnosis their fatigue (Borneman, 2007). Barriers at the professional levels, include a lack of knowledge about the complex nature of fatigue. Also there is lack in literature agreement about the definition of fatigue, it’s causes, effects and remedies used for fatigue management. Usually health care providers focus on managing pain and nausea because they interfere with quality of life but fatigue is not considered one of these symptoms that needs to be addressed.

Some of the negative effects that contribute to airplane accidents are related to fatigue. Associated mainly with long flights, irregular work schedules performed by pilots may lead to incidences such as menstrual irregularities, stomach problems, weight gain, cardiovascular problems, and cold flu. Unfortunately, there are attempts to provide limitation on flight time and scheduling provisions to pilots.

Fatigue is a growing concern and issue in the aviation industry. Although it has been for some time, recently mounting workloads and stress have factored into creating an escalating problem with real casualties and repercussions. “Pilot fatigue, heavy workloads… may have contributed to an air ambulance crashing into the sea at night during a medical mission…” (Crash Blamed 2006 p.31). Fatigue is an “insidious” condition that affects a pilot in a way that might make him feel justified in his decisions. (Wald 2008 C3). Without realizing the effects of sleepiness and stress, pilots often times make the wrong decision, believing it to be the right one, and suffering severe consequences, such as: passenger injures, crew injuries or even

The best empirical evidence for the effects of fatigue on behavioral restraint comes from studies which show that self-regulatory failure can be overcome with an increase in success importance. In these studies, resource depleted participants are shown to be unable to resist an urge unless they are presented with a performance incentive. This is because when the depleted (high fatigue) individuals are presented with the behavioral restraint challenge, they perceive the urge as excessively difficult to resist against in comparison to their low level of success importance, due to the fact that no reward was being offered. This leads to effort being withheld and no behavioral restraint. In contrast, once an incentive is offered, the participants’

Fatigue in athletes may be thought of as presenting on a continuum: More transient states that last hours or days (as in overreaching) to chronic states that may take months of rest or reduced activity, as well as other interventions, to resolve (Derman et al., 2000). Moreover, repeated, exhaustive, successive exercise may increase the risk of chronic immunodepression (Castell, 2003). Along this continuum, Budgett (2000) recognizes a fatigue state termed Unexplained Underperformance Syndrome (UPS), defined as "persistent performance deficit despite 6 weeks relative rest". This time frame differentiates UPS from Chronic Fatigue Syndrome (CFS), a hallmark of which is symptoms lasting at least 8 months. As in UPS, Overtraining Syndrome

Feeling tired in a short span of time or after a hard day’s work, then taking a rest for a while or having a good night's sleep is just the expected routine in regaining strength and energy in our body. If this is not the case for you and felt that after resting, napping or snacking, no longer suffice to give a boost to your energy because it has rather become a prolonged feeling of tiredness, then you must be experiencing fatigue.

In todays society it is no longer a question but a fact that pilot fatigue is a major threat to flight safety. Fatigue has been cited as a factor in several accidents and serious incidents in recent years. Over the last decade a substantial amount of research and case studies have been conducted on fatigue and pilot performance. All of which have scientifically proven that fatigue reduces the physical and mental awareness of one’s ability to operate a plane safely. This is due to the long duty days, circadian disruptions from night flying, time zone changes leading to jet lag, stressors, and insufficient rest or sleep periods. In general, these studies have shown that a fatigued person may lose up to 80% of his or her attention capabilities

In the medical field sleep deprivation or fatigue is a common experience among medial professionals, including nurses. With shift work and maintaining quality care for patients, among other contributions, limits the time nurses can designate to sleep each night. An inadequate amount of sleep causes the body to fall into deprivation, which many describe as fatigue. Fatigue contributes to less quality care for patients by effecting the personal health of nurses, the job strain on nurses, and the burnout rate of nurses.

Fatigue of the crew, and mismanagement of their afforded rest periods also contributed to the incident. The most rested member in the flight station was the pilot monitoring with 3 hours of sleep in the previous 24

I believe it is unfair for others to suffer from poorly made decisions by people; however it is only human that our brains pay a biological price from making decision after decision. This concept is extremely intriguing and proves correct because of the facts provided within the article, as well as the fact that it is something I recognize with myself and others. I recognize that I suffer from decision fatigue when required to make a lot of decisions. Eventually my brain gets tired of making choices and I begin to get lazy and choose the easy way out after a long day of decision-making and using willpower. In fact, eating does help, specifically foods with glucose. Typically I do not enjoy candy; however I do recognize a rare craving for candy

Preparatory seeing about fatigue failure of metals grew in 19th century amid mechanical unrest in Europe when substantial obligation trains, boilers and so on fizzled under cyclic loads. It was William Albert who in 1837 initially distributed an article on fatigue that built up a connection between cyclic load and strength of the metal. After two years in 1839, Jean-Victor Poncelet, fashioner of cast iron axles for plant wheels, formally utilized the term fatigue without precedent for a book on mechanics. In 1842, one of the most noticeably awful rail debacles of 19th century happened close Versailles in which a train broke an axle. Examination of broken axle by William John Macquorn Rankine from British railroad vehicles demonstrated that
