Alhamdulillah, I am greatly indebted to ALLAH SWT on His blessing for making this study successfully. I would like to express my gratitude to honorable Dr. Razali Bin Ngah, my supervisor, for his guidance, support and encouragement throughout my study. I am also thank you to my colleagues for providing an enjoyable study environment at UTM. Finally, I would like to thank my husband and my mum, angah, nini and aishah for their full support and patience. For my baby, I hope to make up for all the lost time that we have not spent together. Dedicated to my loving husband & family, ABG HAKIM & MAMA, ANGAH, NINI, AISHAH and my adorable childrens HAZIQ,WIDAD AND ZIYAD.
