At first stage, assessment items are suggested by investigating foreign methods and analysing the results of first questionnaire. And next, assessment standards are proposed by considering the related regulations and standards in Korea and analysing the opinions in second questionnaire. Through these process, the EAMMURE is developed. This method is still not final version. There is a need to update according to the development of related technology and assessment methods.
