Dear Rebecca,<br /><br />I glad that you are okay with my acknowledgment asking. I will put your name then. <br /><br />Thank you also for your help on the abstract. It's a lot better with your touch as usual.<br /> There is one question I would like to ask. The last sentence I wrote is this below,<br /><br />One of the reasons that the question of the origin of modern Japanese has been left in confusion may have been caused by the result that Korean ethnic involvement has not been enough considered in the research process.<br /><br />Although abstract generally should be short and clear words with our findings or suggestions,&nbsp; What I was really trying to do with the sentense above was not a direct way but more likely implying way of what I wanted to say (all the paper words you are now readings is about that. I am not strongly saying that they did this, this and this but I am trying to imply that what they did in the past was on purpose. And now that the reason for making a difficulty on the subject of the origin of Japanese things is because of that-I hope also this helps when you read my paper - any comments about my strategy (what I just said) will be really appreciated). I do not know what to say but any possible way to do that way with better English words on the abstract?&nbsp;<br /><br />Thanks for your time to read this long message. <br /><br />Jaehoon, <br /><br />
