I am also very grateful to my committee members, Dr. Architecture Lab for their valuable time and friendship. And I would like to thank Jaesung for being my supporter during my study. Lastly, to my mother who has passed so many sleepless nights thinking and praying for the children, and my brother Wonsuk and Minja for providing encouragement throughout my life.
