Hi again, Jaehoon - I've looked at the sections in red, and I made a couple minor editing suggestions.&nbsp; I hope you're not serious about giving up on this work!&nbsp; I understand how stressful it must be.&nbsp; What you write about seems like an interesting and important subject, and I've seen many writers who don't think&nbsp; as clearly or write as coherently as you do!&nbsp; Don't be discouraged!&nbsp; Let me know if you have&nbsp;any other questions or comments. &nbsp;RebeccaTDE
