本研究以182位，年齡20~58歲 ( 28.0 ± 8.6 ) 未受職業性振動暴露的男女教職員、學生為研究對象。於室溫 ( 25 ± 1℃ ) 的環境下，利用振動覺測定器及皮膚測定器，進行: (1) 室溫下右手食指、中指、環指之皮膚溫及振動覺閾值；(2) 10℃冷浸10分鐘之食指皮膚溫；(3) 冷浸後皮膚溫及振動覺閾值等的測定。利用統計分析皮膚溫、振動覺閾值與其它變數如性別、年齡、肥胖度之相關性。結果發現，隨年齡的增長皮膚溫有升高、振動覺閾值有減低的趨勢。以複回歸分析各變數與皮膚溫及振動覺閾值之關係顯示，室溫下皮膚溫，於不考慮性別因素下，以年齡的相關性最大，區分性別後，在男性年齡和肥胖度可以有意義預測皮膚溫，女性則與各變相無相關。各變項與震動覺閾值關係，顯示室溫時相關性較大的為年齡，經冷浸後則以皮膚溫的相關性較大。本結果可供有意進行國人正常情況下震動覺閾值及皮膚溫調查研究之參考。 This research was based on 182 female and male faculty and students aged 20-58 years (28.03 + 8.6) never exposed to occupational vibration. The vibro-meter and skin-temperature-meter were used to undertake the following measurements:(1) the skin tem-perature and vibatory perception threshold (VPT) of index, middle and ring fingers in room temperature; (2) the skin temperature of index finger in I0℃ cold water for 10 minutes; (3) the skin temperature and VPT after cold-water-immersion-test. All of the measurements were practiced m right hand and room temperature was kept at 25±1℃. Correlation matrix was used to diagnose the correlation between the skin temperature , VPT and variables such as age ,sex and fat index. This survey shows that the age is positively correlated with skin temperature, but negative correlated with VPT. By using the multipe regerssion model to analyse the correlation between skin temperature, VPT and other variables, the following results are found:(1) the age including female and male has the highest correlation with the skin temperature under room temperature;(2) the male skin temperature can be predicted significantly by variables age and fat index, but female skin temperature has nothing to do with any variables;(3) the age has higher correlation with VPT under room temperature than sex and fat index, (4) , the skin temperature has the higher correlation with VPT after cold-water-immersion than in the room temper-ature. These results would provide a available information for studing the skin temperature and VPT under normal condition.
