Dear Kris, Jonathan, Robert, Thanks for all your valuable comments. Comments from industries are really appreciated, as i always asked whenever i presented the documents. I'm now quite tied-up by other meeting in Argentina, so i will update the document applying the comments as soon as I return back (next friday).
I also appreciate Daniel, Carl, Kihyong, Jungsoo, Hamid, Saif, and other 6lowpaners who sent the support.
