BBS電腦族操作習性與視覺疲勞研究

目標：電子佈告欄系統(BBS)具有虛擬電子社區的特性，在長時間的電腦操作下，可能會對身體造成傷害，尤其是視覺機能方面。本研究的目的是欲探討BBS族群的特性及電腦工作站之操作環境與視覺疲勞的相關。方法：研究期間先將問卷張貼在網頁上，選擇上站人數最多的前三名BBS站作為問卷訪查的母群體。在BBS線上隨機抽樣傳送訊息給使用者，再給予他們問卷的網址，讓其登入作答；若受試者對問卷內容有疑感，可以在BBS上傳送訊息跟研究者詢問討論，此調查方式如同現實社區的家訪。結果：問卷回收率87.3%，BBS族群以學生為主(74.6%)，絕大部分為大學生(59.7%)；男性平均每週上線16.21小時，女性10.95小時，男性比女性花較多時間於BBS上；女性在每次電腦操作後，眼睛酸澀、想睡及頭痛的發生頻率比男性來得高；電腦操作環境的滿意度與視覺疲勞的發生頻率呈負相關。結論：利用BBS虛擬電子社區的特性來進行研究，是一個具有高問卷回收率的線上調查方式；電腦終端顯示器(VDT)品質越差者，使用者越是容易覺得疲勞，所以改善電腦工作站的設備環境，是減少視覺疲勞的一種有效方法。

Objectives：The Bulletin Board System (BBS) resembles a virtual community. Spending long hours on this system is detrimental to the body ,especially the visual function .This study aims at fatigue. Methods：The questionnaire was posted on the three most popular BBSs. Random sampling by the BBS users’ numbers,sending messages to the subject one by one ,offering the researcher’s e-mail address and asking them to answer the questions which were processed on-line . If there was any problem related to the questionnaire, the participant could send a massage to the researcher and discuss it .This interviewing technigue was the same as real-word face to face interviews in the virtual community .Results：The questionnaire return-rate was 87.3%. Most users were university students (59.7%) . On average ,male subjects spent 16.21 hours per week. This was more than females (10.95 hour per week). However, female subjects suffered from visual symptoms (eye soreness, drowsy , headache) more frequently than the males. There were signififatigue. Conclusions：Because BBS is a virtual community ,using an on-line questionnaire survey allowed for a high return rate. Subjects with a high degree of visual fatigue seemed to use worse visual display terminals (VDT). Thus ,improving the work environment and equipment of VDT workstations is necessary to decrease the symptoms of visual fatigue.
