Hi, Oh-Jung:<br /><br /><br />I have uploaded your edited document, and I hope that you find the suggestions helpful. If you have any questions, please send a message to me via Editor World.<br /><br />Your responses were much better than you give yourself credit&nbsp;for, which made my job so much easier. I may have misunderstood&nbsp;about one or two of the paragraphs, so if you need further editing, just and copy and paste the paragraph and send it&nbsp;as a message via Editor World. I'll be available all day if you need any further help. From what I read, your paper is well worth publishing. Good luck!&nbsp;<br /><br />Although I was careful not to change the content, please proofread the edited document carefully.<br /><br />Best wishes - George (TypeRighter)<br />I am usually available for editing between 6:00 am and 10:30 pm (EST). If my status is set to 'unavailable', you can still reach me via Editor World.
