Introduction
Today we live in a global community as global citizens where we have become increasingly conscious about sharing the planet with people from other cultures and backgrounds. In this global community where so many technologies are shared, distances and time barriers have shrunk. Not only can we use information technologies to e-mail, phone or fax friends, family and colleagues in other parts of the world, we can also use reliable and regular travel links to visit them, covering vast distances in a matter of hours.
