工商發達的社會，競爭激烈且工作壓力大，過勞死之案例時有所聞，疲勞不但影響人體健康亦增加意外事故發生機率，尤其系統對人員之要求較高之作業，若人員因疲勞而降低對系統變化之反應能力，將導致事故之發生。本研究以咖啡為提神飲料，以腦波測定所推衍之腦波能量指標(EEG power indices)量化心智活動狀態，並使用自覺疲勞評估量表，藉以探討神提飲料對於消除疲勞的效果。本研究以22位年齡18至24歲之學生為受測者，實驗分為前測及飲用提神飲料後持續量測腦波30分鐘，以前測為第一階段，飲用提神飲料後30分鐘內三階段進行分析。測量結果發現覺醒水準β/α及困倦水準(θ+α)β皆有顯著變化，顯示飲用提神飲料後對於消除疲勞的程度有顯著差異，表示提神飲料對於大腦精神狀況、訊息傳遞、視覺皆有消除疲勞之效果。由個人主觀上室內作業自覺疲勞評估量表，顯示飲用提神飲料前後，對於消除疲勞的程度也是顯著的，表示個人主觀對於提神飲料消除疲勞的效果是明顯的。綜合上述實驗量測經由主觀量測及客觀量測得知本研究結果，提神飲料對於消除疲勞的程度是一致的，且會隨著時間而更佳。 Recently, many kar?shi cases were found in industrial society, work pressure and intense competition,, the fatigue not only affect human health also increase the probability of accidents, especially in the relatively high requirements of system operations team staff, if the staff is reduced due to fatigue the ability to change the system, it will result in an accident. In this study, we attempted to evaluate the effect on dispelling fatigue for freshener (coffee was used) by Electroencephalography (EEG), in order to explore the effect on freshener for dispelling fatigue. 22 college students aged 18-24 participated as volunteer subjects. The experiment was divided into before, during and after drinking coffee. Three stages were used in this study including before drinking as first stage, drinking lasting 30 min as second stage, after drinking for 30min as third stage. The results showed that the awaked level and drowsiness level had significantly changes. It shows that drinking coffee had a significant effect on dispelling fatigue. The indoor job consciously of subjective the fatigue assessment scale, showing before and after drinking refreshing drinks, the degree of dispelling fatigue is also significantly. For the subjective refreshing drinks for relieving fatigue the effect is also obvious. The finding is the effect on dispelling fatigue by consuming coffee is not overall. Drinking coffee to dispel fatigue may be partially effective. It provides the coffee consumers renew the concept of the effect on dispelling fatigue by drinking coffee.
