I would like to express my sincere thanks to my seminar advisor, Dr. Paramee Noonim for her invaluable help in format proofing, proofreading and constant encouragement throughout the course of this seminar. I am most grateful for her teaching and advice, not only the research methodologies but also many other methodologies in life. I would not have achieved this far and this seminar would not have been completed without all the support that I have always received from her.
