Hi, YJH:<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 />This is an excellent paper that needed just a little finessing here and there. My original plan was to incorporate the edits into the submitted document, but then I realized that&nbsp;since pdf editors have as yet no track changes feature, you would have trouble finding the edits to accept or reject. Then it occurred&nbsp;to me that you will probably want to include the edits in your original document anyway, and create a new pdf. With that in mind, I decided to include the edits as comments on your submitted document. This way you can easily see the recommendations and transfer them to your original document if you wish. I believe the edits are self-explanatory, but if you have any questions, please send a message to me via Editor&nbsp;World and I will reply as soon as possible. <br /><br />Although I'm far from an expert, your paper is an extraordinary intellectual&nbsp;endeavor. My compliments!&nbsp;<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.
