Firstly, I want to express my sincere gratitude to my advisor, Prof. Kyoung Kwan Ahn, for all of his guidance, advice and support during the course of my research and thesis writing. Forever I will remember the opportunities he has provided me, for his constant support and his initiative ideas and suggestions. My respect for him will always be in my mind. I am also honored to have Prof. Byung Ryong Lee, Prof. Soon Young Yang, Prof. Cheol Geun Ha and Prof. Jung Ho Park in my committee, whose inspiration, support and perseverance made this dissertation become possible. I would like to thank them for their interest and encouragement throughout this research. No words for me to express my sincere gratitude towards all my Korean, Bangaldesh and Vietnamese friends (Thanh-Hon-Nam-Hao-Kha-Tu-Truong-Hanh-Hung-JongIl-Amin-Mafuz and others). Not much happy people like me to have their best friend. Thanks for helping me to pass through difficult moments, for yours deep thinking and yours contributions to the realization of my thesis, and especially for the many animated discussions on the subject. This thesis is dedicated to my darling wife Le Tan Loi, my sons Bim-Bum and my girl Bo. Special sentiment is also expressed to my sisters, my brother Huy Don and their family for taking care of me during the time I studied abroad. Finally I dedicate this work to my father and my late mother. Their endless love for me always supports me in all my life.
