Description
Technical field
The present invention relates to technical field of biological, and in particular to a kind of air traffic control person teams and groups are slightly with
Spend the detection method of degree of fatigue.
Background technology
The history of human research's fatigue can trace back to the World War I before a century earliest, in Great War and postwar Britain
Industrial fatigue research committee (renames as The after The Industrial Fatigue Research Board
Industrial Health Research Board) carry out one on fatigue in industrial production particularly military material production
The extensive ergonomics research of problem.The research report has a far reaching influence, or even many results are into the common recognition of industrial quarters.For example,
It the report recommends and shorten long working time, improve alleviation employee's fatigue such as working environment, adjustment break tour system, improve work life
Yield.These suggest design and the break tour systems such as the illumination to our working time settings now, workshop and working environment
System optimization still has directive function.The index for being used to detect fatigue in this part of report is exactly labor productivity.
In World War II, aircraft industry particularly military aviation industry is quickly grown.It is found that pilot exists
During button aircraft execution task, it may appear that driving ability declines the situation of even disability suddenly, it has been proposed that to operate achievement
Effect declines to characterize fatigue.After the war, develop with military aviation and Civil Aviation Industry, long-distance flight and round the clock flight become
It is more and more common, it has been found that fatigue problem more complicates, and fatigue can add up, and forms accumulation fatigue.This period, still
Based on ergonomics technique study fatigue.
The continuous improvement paid close attention to people social safety, the research for fatigue problem are also expanded by ergonomics research
To subjects such as psychology, Neuscience, hypnosphy, Physiology and biochemistries.The method that each subject establishes corresponding detection fatigue, such as the heart
Stamford Sleepiness Scale of the Neo-Confucianism based on subjective feeling, Visual analogue scale etc., the also prestige based on cognitive ability detection fatigue
This Kang Xing card sorting test (WSCT), Tower of London test (TOL) etc..Subjective scale is vulnerable to mood and other factors interference,
Parameter index setting is relatively difficult in recognition tests, " ceiling " or " floor " effect often occurs, causes these scales or soft
The reliability and validity of part are not satisfactory enough;And for example nerve and sleep science are established based on electroencephalogram change detection fatigue method,
It is proposed occur fatigue when delta and theta ripples significantly increase, because Brain Diagnostic Apparatus is complicated, it is difficult to applied to Site Detection;For another example
Occur yawning during based on human-body fatigue, the dynamic change of eye such as blink, catacleisis physiological reaction, attempt to establish accordingly detection side
Method.So far, people are understood tired biochemical mechanism seldom, and the explaination of tired biochemical mechanism will be helpful to exploitation based on biochemistry
Index it is objective, stably, quick detection fatigue method.
It is a kind of method that people have attempted to using biochemical indicator detection fatigue, such as detects some hormones, peptide, studies
It was found that cytidine (Cytidine) and adrenal cortex class ester alcohol (Corticoid) concentration are relevant with operating pressure;Also examine
Survey the material relevant with sleep, biological rhythm such as glycopeptide (Glycopeptides);But Borbely etc. point out these compounds with
Fatigue has the evidence of the data deficiency uniformity of correlation.In a word, although people are from operating pressure, sleep, biological rhythm etc.
Multi-angle has attempted multiple compounds metabolism and tired correlation research, but does not find any body metabolism compound yet
There is correlation with fatigue.
Metabolism group is the new branch of science of metabolic characteristics in a system research body, mainly using nuclear magnetic resonance, gas phase
Chromatography-mass spectroscopy, liquid chromatography-mass spectrography etc. test and analyze means combination Chemical Measurement, systematically explore, find and find human body
The characteristics index of its body fluid metabolic is biomarker when being influenceed by disease, medicine etc., in medical diagnosis on disease, medicament research and development etc.
Field obtains extensive use.For example, Mapstone of Georgetown University of the U.S. etc. is using LC Mass (liquid matter point
Analysis) metabolism group method, examination goes out 10 kinds of characteristic biological marks, can be in the disease for detecting alzheimer's disease
2-3 is diagnosed before clinical symptoms occurs in disease, and accuracy rate can reach more than 90%;And for example, Naviaux etc. is using liquid matter point
Technique study chronic fatigue syndrome metabolic characteristics is analysed, it is found that male patient has 8 kinds of metabolins, 13 kinds of metabolism of female patient
Thing occurs significantly to sexually revise, Subject characteristics' sex work curve (Receiver operator characteristic curve,
ROC) analysis result shows that accuracy rate of diagnosis reaches 94% (male) and 96% (women);Professor Xu Guowang etc. is using the analysis of liquid matter
Metabolism group research is carried out to depression and fatigue rat model blood and urine, the results showed that two groups of rats are with compareing
Group rat is compared, and anomalous variation occurs in metabolism.Armstrong etc. samples two dimensional NMR energy disperse spectroscopy to chronic fatigue syndrome
Patients serum has carried out metabolism group research, the results showed that case group serum GLN and ornithine content are substantially less than pair
According to group.In above-mentioned document report, packet comparison is carried out using case group and control group for various diseases, but because fatigue is
A kind of physiological change that can recover, existing literature method are not suitable for the screening of degree of fatigue associated biomarkers.
Air traffic control person, the air traffic air route that takes charge are boarded a plane safe operation, are generally just referred to
Aircraft is waved, manages all airborne vehicles in whole spatial domain as a whole with reference to information such as radars.Controller often commands simultaneously at work
The operation of multi-aircraft, it is necessary to energy concentrate, the ability such as accurate judgement and emergency processing, therefore be very easy to fatigue, civil aviation authority
Relevant regulations clearly every controller is no more than 2 hours in seat commander's aircraft maximum duration.It is main that fatigue is produced in its work
It is caused by mental labour.Chen etc. utilizes liquid chromatography-mass spectrometry in the literature, to the urine of air traffic control person
3 kinds of tired associated biomarkers of screening sample, but the concept of degree of fatigue is not proposed, in addition do not disclose yet and to utilize fatigue
The method that associated biomarkers detect air traffic control person's degree of fatigue.The present inventor is established available for people early stage
The method of body fatigue associated biomarkers screening.On this basis, the present inventor has found by substantial amounts of experiment, degree of fatigue
It is related to air traffic control person's potential job safety executive capability, therefore degree of fatigue detection can give civil aviaton's air traffic pipe
Member's security risk management and control processed provides strong new technology and new tool.
The content of the invention
