The accomplishment of this research study would not have been possible without the support of many people. First and foremost, I would like to express my gratitude to the Japan Government for providing me with the opportunity to study at the Asian Institute of Technology (AIT). Specially, I would like to acknowledge Dr. Ekbordin Winjikul, my advisor, for his invaluable advice, insightful suggestions, and unwavering encouragement. Furthermore, despite his busy schedules, I can always reach him in some way if I have concerns or queries concerning my studies. He let me build my thesis entirely on my own ideas and approaches, but he guided me in the proper direction whenever I encountered an obstacle. In addition, I'd like to express my gratitude to the professionals who participated in the validation of this study: Prof. Nguyen Thi Kim Oanh and Dr. Tatchai Pussayanavin. They not only helped with the validation process, but they also provided me with great insights and recommendations that I will use in future projects.
