ABSTRACT
@#ObjectiveTo explore the correlation between psychologic status and personality characteristics of certain recruits.Methods168 recruits were surveyed by Symptom Checklist 90 (SCL-90) and Eysenck Personality Questionnaire (EPQ).ResultsIn 168 recruits, the factorial scores including interpersonal sensitivity, hostility and phobia were higher than the norm of Chinese and PLA (P<0.05～0.01). In junior high school recruits, the factorial scores including hostility and constrain were higher than the senior school recruits (P<0.05). Certain recruits showed higher scores of factor P, factor N, and lower scores of thinking factor, factor E and factor L and all the factors of SCL-90 compared with the norm of Chinese.ConclusionThe mental status and personality characteristics of certain recruits are poor. The company should strengthen psychological education and quickly adapt the recruits to the military circumstance.

ABSTRACT
<p><b>AIM</b>To investigate the effects of mild and moderate hypoxia on human cognitive performance.</p><p><b>METHODS</b>Eighteen healthy young male volunteers performed a set of tests of human ergonomics at sea level (300 m in Xi'an) and simulated high altitude of 2 800 m, 3 600 m and 4 400 m for 1 h in hypobaric chamber, respectively.</p><p><b>RESULTS</b>The performance of continuous recognition memory tests compared with the controls' was deteriorated significantly (P < 0.01) after exposure to 2 800 m for 1 h. After exposure to 3 600 m for 1 h, in all test, the reaction time was much longer, the accurate rates were lower and the performance was worse than that of control (P < 0.05). All the parameters were deteriorated with the increment of altitude and the performance of all tests were much worse at 4 300 m for 1 h (P < 0.01).</p><p><b>CONCLUSION</b>Different parameters of human cognitive performance may have different susceptible thresholds to hypoxia according to the results from our studies. The cognitive performance after exposure to 3 600 m for 1 h was not sufficiently effective for the demands of human ergonomics due to its significant deteriorating changes. However, the performance can be effectively restored after exposure to enough oxygen supply for 1 h.</p>
