Measurement of Military Aircrews’Ability to Adapt to The Equipment of Human Centrifuge

[[abstract]]本 研 究 運 用 Ras ch 模式， 量測國軍空勤人員適應人體離心機 裝備之能力， 由受測者之能力差異性對裝備所呈現出壓力源的難 度， 即可估算出題項的難度差異， 研究結果可成為教育訓練與工 程人員後續改善方針， 有效提升國軍空勤人員G 耐力訓練， 並降 低大G 昏迷事件發生。研究過程使用問卷方式， 一共蒐集完整有 效問卷計5 0 1 份， 後續採用項目反應理論進行結果分析， 研究結果可得知受測者於執行人體離心機訓練時， 因能力的差異性對裝 備所呈現適應之壓力高低不同（ 即題項難度差異）。此外另本研究 亦以試題功能差異性執行分析， 依群體的特性進行分類， 以進一 步瞭解不同的群體對題項的難度差異是否相同， 與兩群體所呈現 的差異性為何， 來找出對特定群體的有效改善作為。[[abstract]]This study used Rasch method to investigate military aircrews’ ability to adapt to the equipment of human centrifuge, from the ability difference of the persons who are examined to equipment the degress of difficulty of the stress source. It can estimate degree of difficulty difference of item. Become between instructors and engineers improve the policy. To promote trainees’ G tolerance to lower the G-induced loss of consciousness（G-LOC）event for the crews of high-performance combat aircraft. First, use questionnaires to assess the stressor for crews in taking centrifuge training and measure trainees’ ability to adapt to the equipment, and adopted item responses theory in follow-up for collecting effective questionnaire from 501 respondents. In the result of student, because aircrews’difference of ability to adapt to the equipment the stressor level appeared differently when carry out human centrifuge training. In addition we used differential item functioninf to research. In order to understand whether different groups are the same to the difference of order of degree of difficulty of one of the question, and why with the diference that two groups appear. To find out the effective improvement conduct to the specific group
