Abstract:
INTRODUCTION: Fatigue is an important phenomenon in modern aviation. Despite the progress in research concerning fatigue among civil aviation and military pilots, fatigue in student pilots has remained unexamined. The aim of this study was to examine fatigue among ab-initio pilots. In this study, the fatigue model previously proposed and used in the literature is redesigned for ab-initio pilots.METHOD: A 48-item questionnaire was applied. Factor analysis was performed using SPSS. The data were collected from 114 ab-initio pilots.RESULTS: It was determined that 23% (N 26) of the participants included in the study were women and 77% (N 88) were men. When the license types of the participants were analyzed, it was seen that 11% (N 13) had commercial pilot licenses (CPL; N 80), 70% had private pilot licenses (PPL), and 18% (N 21) had student pilot licenses (SPL). Results showed that seven performance factors (types of flight, training scheduling, crew composition, environment of the aircraft, types of accommodation, flight training-related issues, and biological issues) affect ab-initio pilots fatigue on various levels.DISCUSSION: The findings may help flight training organizations and ab-initio pilots take assertive preventive measures against fatigue.Kilic B.

Abstract:
Performance decrement associated with pilot fatigue is considered a leading contributor to aviation accidents and fatalities. The output of prevalent pilot fatigue methodologies (both subjective & objective) either suffer from human judgement bias or require complex data processing. Moreover, studies catering to long duration flight missions have not been performed. Presently, we investigate the impact of fatigue on pilot performance for long duration of a flight mission composed of multiple take-offs and landings. We propose a new multimodal approach that integrates traditional fatigue metrics with eye tracking methodology. The effect of fatigue on the pilots’ eye movements was evaluated using information theory-based entropy measures. Results showed an increase in the fatigue level (measured by mean reaction times and the number of lapses) with increase in flight duration. The entropy measures showed that visual attention distribution and scanning strategy both became random in nature as fatigue level increased in pilots. Obtained results suggest fatigue decreases both information searching and processing capability in pilots. The proposed method can show which aspect of the pilot performance becomes impaired by fatigue and thus can be applied to evaluate fatigue onset in real time, which enables timely recovery interventions.

Abstract:
This study attempts to examine the fatigue of pilots who fly the commercial aircraft on short route since they have to make several take-off and landing during their duty time for short route flight. The method of paired t-test was used to measure the condition of the pilots before and after their duty time. In addition, the factors that the pilots most felt in contributing to the level of fatigue were also explored in this study. The results indicate that the pilots experience fatigue when flying short routes in their duty time and the factor that contributes the most to the pilots’ fatigue is the external factor related to their duty as a pilot. Penelitian ini berusaha menggali kelelahan pilot yang menerbangkan pesawat komersial rute pendek, karena pilot yang menerbangkan rute pendek dalam menjalankan flight duty time membutuhkan beberapa kali dalam melakukan take off maupun landing. Penelitian ini menggunakan metode uji t secara berpasangan dengan mengukur kondisi pilot sebelum bertugas dengan kondisi sesudah bertugas, selain itu penelitian ini juga berusaha menggali faktor-faktor terbesar yang dirasakan oleh pilot dalam menyumbang tingkat kelelahan. Hasil penelitian menunjukkan terdapat kelelahan yang dirasakan oleh pilot dalam melaksanakan rute pendek dan faktor terbesar yang menyumbang kelelahan adalah faktor eksternal yang berkaitan dengan tugas mereka sebagai pilot.

Abstract:
Fatigue is an important factor affecting modern flight safety. It can easily lead to a decline in pilots’ operational ability, misjudgments, and flight illusions. Moreover, it can even trigger serious flight accidents. In this paper, a wearable wireless physiological device was used to obtain pilots’ electrocardiogram (ECG) data in a simulated flight experiment, and 1440 effective samples were determined. The Friedman test was adopted to select the characteristic indexes that reflect the fatigue state of the pilot from the time domain, frequency domain, and non-linear characteristics of the effective samples. Furthermore, the variation rules of the characteristic indexes were analyzed. Principal component analysis (PCA) was utilized to extract the features of the selected feature indexes, and the feature parameter set representing the fatigue state of the pilot was established. For the study on pilots’ fatigue state identification, the feature parameter set was used as the input of the learning vector quantization (LVQ) algorithm to train the pilots’ fatigue state identification model. Results show that the recognition accuracy of the LVQ model reached 81.94%, which is 12.84% and 9.02% higher than that of traditional back propagation neural network (BPNN) and support vector machine (SVM) model, respectively. The identification model based on the LVQ established in this paper is suitable for identifying pilots’ fatigue states. This is of great practical significance to reduce flight accidents caused by pilot fatigue, thus providing a theoretical foundation for pilot fatigue risk management and the development of intelligent aircraft autopilot systems.

Abstract:
In order to assess airline pilot duty fatigue levels associated with normal operations, subjective fatigue, sleep cycles were unobtrusively monitored and compared to the estimates of a fatigue prediction algorithm (FADE). A group of 9 commercial airline pilots completed log sheets on which sleep, flight data and periodic estimates of fatigue levels were recorded over a 10-day period. The subjective fatigue scores indicated a significant increase during the 2000-0400 hours time block. The lowest reported fatigue scores occurred during the 0800-1200 hours. Hours of sleep predicted pilot fatigue levels better than circadian time, hours of flight, time zones crossed or hours of non-flying work. A fatigue-estimating algorithm (FADE) used logged sleep data and was well correlated with the subjective reports of fatigue. Use of fatigue algorithms may be useful to select the timing and crew rest considerations of comercial airline routes before they become part of normal operations.

Abstract:
Background: Over 30% of cancer survivors experience chronic fatigue. An alteration in energy metabolism is one of the hypothesized mechanisms for cancer-related fatigue (CRF). No studies have evaluated for changes in metabolic profiles in cancer survivors with CRF. The purpose of this pilot study was to evaluate for differences in metabolic profiles between fatigued and non-fatigued survivors of colorectal cancer (CRC). Methods: Survivors were recruited from the surgical outpatient department and the oncology clinic of a medical center in northern Taiwan. Fatigue was assessed using the Fatigue Symptom Inventory. Fasting blood samples were collected on the day the fatigue questionnaire was completed. Metabolomic profile analysis was performed using non-targeted, liquid chromatography/time-of-flight mass spectrometry. Fold change analyses, t-tests, and pathway analyses were performed to identify differences in metabolomic profiles between the fatigued and non-fatigued survivors. Results: Of the 56 CRC survivors in this study, 28.6% (n = 16) were in the fatigue group. Statistically significant differences in carnitine, L-norleucine, pyroglutamic acid, pyrrolidonecarboxylic acid, spermine, hydroxyoctanoic acid, and paraxanthine were found between the two fatigue groups. In addition, two pathways were enriched for these metabolites (i.e., glutathione metabolism, D-glutamine and D-glutamate metabolism). Conclusions: Findings from this pilot study provide preliminary evidence that two pathways that are involved with the regulation of ATP production and cellular energy (i.e., glutathione metabolism, D-glutamine and D-glutamate metabolism) are associated with fatigue in CRC survivors. If these findings are confirmed, they may provide new therapeutic targets to decrease fatigue in cancer survivors.

Abstract. The present study explores the usefulness of a method to evaluate pilot fatigue based on video recordings. This technique is already being successfully applied in the field of driver fatigue evaluations. Still, to date, there is no known application concerning pilot fatigue. A sample of five trained raters evaluated four active airline pilots on simulated flights using a 9-point fatigue rating scale. The rating scale was adjusted for the aviation context and features 10 subscales relating to different indicators for fatigue. Interrater agreement and reliability, as well as intrarater and retest reliability, were assessed. The results indicate good reliability of the method and medium rater agreement. Raters seem to have established a good mental model of fatigue, leading to consistent evaluations. However, there are also individual rating tendencies as well as the influence of sample characteristics.

Abstract:
This study involved over-the-road testing of four fatigue management technologies (FMTs) in trucking operations in Canada and the United States. Technologies bundled into a single intervention came from four fatigue management domains: one providing objective information on driver sleep need, one providing objective information on driver drowsiness, one providing objective information on lane tracking performance, and one reducing the work involved in controlling vehicle stability while driving. The objective was to determine driver reactions to such technologies and whether FMT feedback would improve alertness, especially during night driving, or increase sleep time on workdays or nonworkdays. A within-subjects crossover design was used to compare the effects of FMT feedback to no feedback. Each driver underwent the conditions in the same order: 2 weeks of no feedback (control) followed by 2 weeks of FMT feedback (intervention). Data from the devices and other driving performance variables were recorded every second of truck operation for 28 days for each driver, with a resulting 8.7 million data records among the 38 drivers. Support was found for FMT effects. During night driving, FMT feedback significantly reduced driver drowsiness (p = 0.004) and lane tracking variability (p = 0.007). However, there was evidence from probed psychomotor vigilance task testing that these improvements may have had cost because of the effort (in attention and compensatory behaviors) required to respond to information from the devices. In general, participants agreed that commercial drivers would benefit from FMT and were more positive about those involving vehicle monitoring than those involving driver monitoring.

Abstract:
Abstract Fatigue is one of the most bothersome symptoms reported by patients diagnosed with cancer, and research indicates that the majority of patients receiving chemotherapy report symptoms of fatigue. Fatigue can have an effect on quality of life; therefore, it is essential that healthcare providers gain a better understanding and recognition of fatigue. Fatigue can also be a symptom of depression. Depression is another prominent symptom reported by patients diagnosed with cancer. Unfortunately, there are similarities between the symptoms of depression and fatigue making it difficult for health care providers to distinguish between the two. This study utilizes the subscale of the Hospital Anxiety and Depression Scale and the Multidimensional Fatigue Scale-Short Form to further investigate the relationship between cancer-related fatigue and depression. The convenience sample consisted of 30 chemotherapy patients being treated at an outpatient infusion center in a comprehensive cancer center in southwest Florida. All participants were between the ages of 26 and 74, and had been receiving chemotherapy for a minimum of three weeks; none had been diagnosed with chronic fatigue syndrome, or were currently being treated with radiation. The participants in the study self-rated their fatigue on a Likert-type scale of 0-10. The mean score on the self-rated fatigue scale was 4.03 (SD= 2.76). This study supports prior studies in which chemotherapy patients report mild to severe levels of fatigue. The mean score on the depression subscale of the Hospital Anxiety and Depression subscale was 4.53 (SD=4.2). A statistically significant correlation was noted between cancer-related fatigue and depression, utilizing the Hospital Anxiety and Depression subscale score and Multidimensional Fatigue Inventory-Short Form total scores (r=.676, p=.000). This study provides evidence that tools such as the Hospital Anxiety and Depression Scale and the Multidimensional Fatigue Inventory-Short Form can aid researchers and providers in distinguishing between fatigue and depression. Using these instruments in future research and practice may help avoid the overlap in symptoms of fatigue and depression. These study results support findings from previous studies indicating a moderate correlation between cancer-related fatigue and depression. This study addresses the correlation between cancer-related fatigue and depression in chemotherapy patients which may improve nursing assessment of fatigue and depression in this population. Findings suggest the need for ongoing research focusing on cancer-related fatigue and depression as well as appropriate pharmacological and non-pharmacological interventions to improve the quality of life of this patient population.

Abstract:
Thesis: S.M., Massachusetts Institute of Technology, Department of Aeronautics and Astronautics, 2016.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 265-268).<br>Fatigue is a concern as it decreases performance, increases operational risk, and generates significant annual costs. Of particular concern with small satellites is the operation of multiple robotic assets. SPHERES, a small satellite testbed, was used to examine the effects of fatigue and presence of an augmented display with situation awareness aids. All procedures were approved by the MIT Committee on the use of Humans as Experimental Subjects. Subjects (n=8) were trained on the system, then randomized to a sleep protocol order, which included 3 days of rest and 3 days of sleep deprivation. Subjects controlled two satellites in a space debris avoidance scenario. Dependent measures included survival time, strategy used, fuel usage, secondary task reaction time, and responses to a situation awareness questionnaire. An ANOVA found significant interaction effects of sleep protocol order and fatigue state on survival time (p=0.008). For these pilot data, a post-hoc test showed better performance on day two if order was rested on the first day and partially sleep deprived on the second day (p <0.05). A successful strategy to increase survival time in the space debris avoidance task was to cover a large area. An ANOVA showed an interaction effect of order and fatigue condition (p = 0.001) on the use of a correct strategy. For these pilot data, a post-hoc test showed the highest area covered on test day two if order was rested on the first day and partially sleep deprived on the second day (p <0.05). A chi-square test for independence found subjects that were partially sleep deprived on the first day received no benefit from the augmentation while subjects that were rested on the first day did receive benefit (p = 0.018). Augmentation had no significant effect on survival time. The study results suggest that a mental model was easier to develop if the subjects were rested on day one due to a better performance and use of a sound strategy on test day 2. Here the augmented display may have assisted mental model development on subjects who were rested on day 1, as it led to improved situational awareness of the satellite's system states; this ability to use the augmentation is associated with better test day 2 performance. These pilot subjects highlight that training guidelines for operating multiple robotic assets should permit appropriate rest during and after training to assist in mental model development and later superior performance.<br>by Jonathan James Schneider.<br>S.M.

Abstract:
Background: Exercise could have a role in ameliorating some of the adverse effects of External Beam Radiotherapy and Androgen Deprivation Therapy (EBRT+ADT) in men with prostate cancer. The primary aim of this study was to assess the feasibility (process, resource and management) and efficacy (scientific) of a home-based moderate-to-vigorous physical activity (MVPA) walking exercise intervention for patients with localised prostate cancer (PCa) undergoing EBRT+ADT in anticipation of a future confirmatory RCT. Methods: PCa patients receiving EBRT+ADT were randomized to a home-based MVPA walking intervention (n=12) or standard care (n=12) for the duration of their EBRT. Intervention patients were prescribed 3000 steps in 30 minutes on 5 days each week, i.e. a cadence of 100 steps/minute. These 3000 steps/day were prescribed in addition to their pre-determined habitual step/day. Fatigue, health related quality of life (HRQoL), anthropometric measures and physical performance were assessed at baseline (planning CT), mid EBRT, end of EBRT, and at 1 month post EBRT. Intervention participants’ satisfaction with the intervention and barriers/facilitators to exercise during EBRT were also assessed. Control group participants’ exercise knowledge, attitudes and practices were assessed post EBRT. The feasibility of the intervention’s processes, resources and management were assessed using quantitative and qualitative methods. Results: The exercise intervention group showed greater improvements in fatigue, quality of life, anthropometric measures and physical performance compared to standard care controls. These improvements were sustained beyond the intervention period. Exercise convenience and treatment centre environment emerged as exercise facilitators. Intervention participants’ average exercise convenience and satisfaction ratings were 4.8/5 (SD=0.4) i.e. “extremely convenient” and 4.8/5 (SD=0.4) i.e. “extremely satisfied” respectively. A lack of time and poor weather emerged as exercise barriers. Standard care controls had poor exercise knowledge, attitudes and practices (KAP) post EBRT, for example only 42% of the control group were aware of the correct recommended weekly MVPA guidelines. Conclusions: This preliminary evidence suggests that a pragmatic home-based MVPA walking exercise intervention is feasible and has the potential to evoke improvements in fatigue, in addition to other important health outcomes in men with PCa undergoing EBRT+ADT. This pilot study has achieved its six feasibility criteria and should proceed to a future confirmatory RCT. Impact: This study shows for the first time that a pragmatic home-based MVPA walking exercise intervention using evidence based tailored exercise prescriptions is feasible and could have a positive impact on fatigue and other key outcomes in men with PCa receiving EBRT+ADT.

Abstract:
There is concern about the indoor environment in aircraft but few stud-ies exist on self-rated health (SRH) and respiratory symptoms among pilots. Occupational and non-occupational risk factors for SRH, respira-tory symptoms and other symptoms among commercial pilots were investigated in this thesis. One cohort study and one prevalence study were performed among pilots in one Scandinavian airline company. Fungal DNA, furry pet allergens and volatile organic compounds of microbial origin (MVOC) were measured on board. Cat (fel d1), dog (Can f1) and horse (Ecu cx) allergens were found in all dust samples and allergen levels were 27-75 times higher in aircraft with textile seats as compared to leather surfaces. The sum of MVOCs in the cabin air was 3.7 times higher than in homes in Uppsala and 2-methyl-1-butanol and 3-methyl-1-butanol concentrations were 15-17 times higher. Asper-gillus/Penicillium DNA and Aspergillus versicolor DNA were more common in aircraft with textile seats. One fifth reported SRH as poor or fair, 62% had fatigue, 46% overweight/obesity and 71% insomnia. Poor or fair SRH was associated with overweight/obesity, lack of exercise, insomnia, low sense of coherence (SOC) and high work demand. Re-covery from work was worse among those with insomnia and low social support at work. Fatigue was more common among young or female pilots and related to insomnia and high work demand. Pilots flying MD80 or Saab 2000 aircraft had less fatigue. Pilots exposed to environmental tobacco (ETS) on board had more eye symptoms and fatigue which were reduced after the ban of smoking (in 1997). Pilots with increased work demand developed more rhinitis, dermal symptoms and fartigue and those with decreased work control developed more eye symptoms. The incidence of doctors’ diagnosed asthma and atopy were 2.4 and 16.6 per 1000 person years, respectively. Pilots changing type of flight got more airway infections. Those reporting decreased work control had a higher incidence of atopy. Risk factors in the home environment included ETS, dampness or mould, window pane condensation in winter and living in houses built after 1975. In conclusion, SRH and respiratory health among pilots are associated with specific occupational and non-occupational risk factors.

Abstract:
Workers’ fatigue is a significant problem in physically demanding occupations. Physical fatigue is known to result in the inability to maintain proper posture and working technique. Consequently, workers lose their ability to safely and effectively perform their duties. Thus, understanding the physical demands of labor-intensive work is of great importance in protecting workers’ safety, and maintaining productivity. Current fatigue assessments methods, including surveys and questionnaires, are subjective and lack reliability. Objective fatigue assessments based on physiological data are more reliable, however they are cumbersome to implement in real work conditions. There is a need for an objective fatigue assessment method that can monitor physical fatigue with minimal intrusion. The goal of this study was to investigate whether jerk, the time-derivative of acceleration, can be used to objectively detect physical fatigue. A pilot study on masons was conducted to determine if physical fatigue can be detected by changes in jerk values. Ten participants performed a bricklaying task using forty-five concrete masonry units (CMU). Seven body segments, namely the hands, forearms, upper arms, and pelvis, were selected for placement of IMU sensors to measure the segment accelerations. Jerk was calculated from the measured acceleration via numerical differentiation. Characteristic values of the jerk at the beginning and end of the bricklaying task were obtained to represent the rested and fatigued states. They were then compared for significant differences. Jerk values calculated from the IMU sensors located on the upper arms and pelvis showed significant differences between rested and fatigued states. The results of this pilot study indicate that the characteristic jerk can be used to detect physical fatigue, however caution must be taken in selecting sensor locations to reduce the influence of spurious signals.

Abstract:
CANDU® nuclear generating stations and their components were designed for 30 effective full power years (EFPY) of operation. Many CANDU plants are now approaching their design end-of-life and are being considered for extended operation beyond their design life. The Canadian regulator, the Canadian Nuclear Safety Commission (CNSC), has asked utilities to consider component fatigue issues in plant life extension (PLEX) applications. In particular, environmental effects on fatigue is identified as an issue that needs to be addressed, similar to that being addressed for license renewal for U.S. nuclear power plants. To address CNSC concerns, CANDU stations have initiated a program to develop component fatigue management programs for PLEX operation. A pilot study conducted in a typical CANDU plant showed that: • Only 10 to 15% of the numbers of design transients have been used after 25 EFPY of operation. Hence, a significant amount of original design fatigue usage margin remains available for PLEX operation. • Environmental fatigue considerations in heavy water (D2O) were included in the assessment. Only warm-up transients are assessed to have dissolved oxygen concentrations that can result in a significant environmental effect for the ferritic steels used in the CANDU primary and secondary systems. • Due to the low accumulation of transients, and the relative absence of thermal stratification mechanisms, thermal fatigue is not as significant an issue in CANDU plants as in pressurized water reactor (PWR) and boiling water reactor (BWR) plants. This paper summarizes the results of the pilot study conducted for the Canadian CANDU plants.

Abstract:
The fusion surgery is a standard treatment for scoliosis. Fatigue-related failure is one common cause for the fusion surgery implant. Due to the high cost of revision surgery, it is of clinical value to study the fatigue behaviors of the spinal implants under physiological spinal loads. In the literature, biomechanical tests and finite element (FE) methods have been used to study the fatigue of the spinal implants. Compared with biomechanical tests, FE analysis has the advantage of low cost and high efficiency. Due to the high computational cost, no FE study has been modeled the exact geometry of the pedicle screw (including the thread) in the screw-bone connection within the multi-level spine FE model. This study introduced a feasible FE-based method to predict the fatigue behaviors of the spinal implants with exact geometry of pedicle screw. One previously-validated FE spine model was utilized to provide physiological spinal loads and was bilaterally fused with pedicle screws and rods at L3-L4 spine levels. The exact geometry of the pedicle screw was simulated in this study for accurate stress prediction. The fused spine FE model was subjected to six loading directions (flexion/extension, left/right lateral bending, and left/right axial rotation). For each loading direction, a pure bending moment of 10 Nm was tested. First, FE analysis was performed for one loading cycle. Range of motion, maximum von Mises stress values of the spinal implants were recorded and compared for the six tested loading conditions. Then, based on the stress/strain history of the spinal implants for one loading cycle provided by the FE simulation, fatigue life cycles of the spinal implants were calculated using strain-based Smith-Watson-Topper equation. Flexion produced the largest range of motion at the adjacent level. Axial rotation produced the largest von Mises stress in the spinal implants. Except for lateral bending, the von Mises stress predicted in the screws fused at the superior vertebra was larger than that in the screws fused at inferior vertebra. The method introduced in this study will be used to study different screw fixation methods in the future work.
