Feedback to this Web site
The JASMA has replaced the former Japan RMA EMA Web Site to this new JASMA
Web Site in September 2011 according to the name change of the organization.
The former site will be kept for 6 months to inform the change of its name
and site address, and to provide an automatic jump function to the new
The development methodology of this site is a "proto-typing"
model, a continuous cyclic improvement process based on test and evaluation
feedback, from a small first trial to the operational one, rather than
the step-by-step, one way, phased processes of a "water fall model".
In such a development process, you can find the latest views of the Web
Site day by day. Your feedback, critical comments or holistic advices,
will be appreciated. Please e-mail your constructive feedback to the following
