You don't refer to the person differently. You just refer to the person normally. Doctoral Degrees come with the title "Doctor," but Master's Degrees do not have a title. If you *want* to call me Master though, I'm okay with it. :)
Calling someone "Master" is a common in Martial Arts. It's more a sign of respect than of subservients. However, it is debatable by some. Many martial arts instructors prefer a translation equivalent to "Teacher" in the respective language, such as "Sensei" in Japanese, "Sifu" in Chinese, "Sabeomnim" in Korean and so on. The belief is one truly never masters the martial arts as it is an ever learning experience.
Like you would call any other person.

Typically a person seeks a Master's Degree after they have successfully completed their undergraduate studies such as a Bachelor of Science Degree. This takes 3-5 years-five years is the norm. A Master's Degree can usually be obtained in another 3 years-but since most candidates pursue this while they are employed professionally-it may take up to six years. In short-the answer is-it depends....Call the University you are interested in and talk to their admissions advisors.
