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.

In this work, we report the design of a new instrument including one heat pulse circuit and three temperature measure circuits. Heat pulse control circuit can control the heating time of heater strip. The heating power is 0.5W and the duty time of every heat pulse is 8s. Three temperature measure circuits can measure the change of stratum’s temperature before and after accurately. The temperature resolution is 0.001°C, precision is 0.01°C and sampling rate is 1 Hz. The instrument can save the temperature data for every measure process. It is also provided with the data communication interface. The data saved in the instrument can export to computer through the interface. The instrument can measure the stratum’s temperature easily and reliably. The instrument will play a role in the studies of hydrogeology and environmental geology besides the application of Shallow Geothermal heat

The purpose of this study was to evaluate the effects of sentry duty time on the soldier's speed of detection of visually presented targets, his ability to hit targets (rifle marksmanship), and his mood. Prior to the test day, each of eight subjects was given five days of training on the Weaponeer Rifle Marksmanship Simulator and was familiarized with the targets to be presented during testing. The test session lasted three hours, during which time the subject assumed a standing foxhole position and monitored the target scene of the Weaponeer. The Weaponeer M16A1 modified rifle lay next to the subject at chest height. When a pop-up target appeared, the subject pressed a telegraph key, lifted the rifle, aimed, and fired at the target. Speed of target detection was measured in terms of the time required by the subject to press the telegraph key in response to the presentation of the target. Marksmanship was measured in terms of number of targets hit. Target detection time and rifle marksmanship were averaged every 30 minutes. At the end of the test session, the subject completed the Profile of Mood States rating scale. The results showed that target detection time deteriorated with time on sentry duty; impairments were not evident within the first hour but were clearly evident by 1.5 hours. Marksmanship remained constant over time; soldiers were just as accurate in hitting the targets at the end of the 3 hours of sentry duty as they were at the beginning. Whereas the soldier's predominant mood during baseline practice sessions was one of vigor, during sentry duty the predominant mood was one of fatigue. The results of this study suggest that sentry duty performance may be optimized if it is limited to one hour or less.

AbstractObjective:To characterize the prevalence and morbidity of injuries to emergency medical technicians EMTs) in New England [United States].Design:A survey was mailed to a 2% random sample of all registered EMTs in the six New England States. The identity of the EMTs remained anonymous, and a second mailing was used to improve return rate. The EMTs were requested to recall events that occurred during the previous six months.Results:A total of 439 of the 786 (56%) surveys were returned representing 13,875 hours of duty time in the six-month period. Seventy one percent of the EMTs were male with a mean age of 35 years. Sixty-six percent were basic-EMTs. Injury attack rates (number of injuries/100 EMTs/6 months) were: stress, 11.2; back, 10.5; extremity, 9.8; assault, 8.4; ambulance collision, 4.1; hearing loss, 2.5; and eye injury, 1.4. Twelve percent of the EMTs were injured more than once in the six-month period. The paramedics more frequently were involved in ambulance collisions, suffered from stress, and were less likely to injure their back. There were minor interstate differences. Disability due to back injury affected 2.5% of those surveyed, four EMTs lost duty time secondary to an assault, and 0.5% of the EMTs were out of work due to stress.Conclusions:This survey begins to characterize the occupational risks of EMTs. The prevalence of back injuries, assault, stress, and extremity injuries seems to be too high. Educational programs and preventive interventions should be designed to minimize back injuries, stress, and assault. There is a need for more research nationwide in order to better characterize these injuries.
