PEER REVIEWER COMMENTS:  
 
GENERAL COMMENTS: The reviewer read the manuscript, and found that the c ontents itself 
is satisfactory. But this manuscript needs editing from the viewpoint of length. The present 
manuscript was well revised responding to the comments by the reviewer, and the reviewer 
considers the manuscript will be accepted for publication, however, there are many concerns not 
the contents of the manuscript but the way of writing. There was so much redundancy in the text, 
and manuscript was too long to be published. More succinct way of writing is required.  
 
If the editor from the publishing company would edit the manuscript to the 1/3 size, I believe this 
manuscript should be accepted.  
 
REQUESTED REVISIONS:  
 
The reviewer considers that the current manuscript should be re -revised in the way that editing 
and removing redundant part of the manus cript. The authors revised well in response to the 
comments from the reviewer, which made the length of the manuscript too long to be necessary. 
There would be several points to be removed from the revised manuscript, making the length to 
1/3 (39 pages to 14, 5 pages). Editing can be requested to either the author side or editing expert 
in the publisher.
