ABSTRACT
With the advent of the twenty-first century, the focus on global health and personal well-being has increased. In 2006, the population of the Earth was estimated to be 6.5 billion,∗ which is expected to rise steadily in the coming years. Health has become more important with recent advances in genetic research, development of new and improved drugs, diagnosis of disease, and the design of more advanced systems for patient monitoring. Health now ranks as one of the most important needs in modern society as evidenced by increasing government funding around the globe.
