Hello,&nbsp;<br />I attached a part of my master's thesis. It's background and purpose of the study part.&nbsp;<br />I'm worried about grammar mistakes, awkward expression, and sentence structure.&nbsp;<br />When you revise&nbsp;my paper, please focuse on those issues, and if you think there is something hard to understand, please leave me a comment.<br /><br />I'll highly appreciate if you revise my paper as soon as possible because I have to submit my thesis to professors within 8 hours.<br /><br />Thank you!&nbsp;
