[Air-L] informed consent

[Tsan-Kuo Chang]

We used two ways to collect informed consent.  In our national mail survey, 
two documents were included: one cover letter and the other consent 
information.  In the consent information, we indicated that when the 
respondent returned the questionnaire, it represented his or her consent to 
participate in the survey.

We also set up an online version for the respondents to participate in the 
survey.  After the respondents logged in, the same consent information 
appeared and the respondents must click on a button to indicate their 
consent before answering any questions.

Best regards.
