Being an institute of higher learning, Assumption University has a definite policy to provide quality instruction to the students, both undergraduates and graduates, and both Thai and foreign nationals. An equally important function of the University is to conduct research in all fields.

Assumption University is one of the leading universities in the field of science and technology. Our periodical, 'AU Journal of Technology', which is now in its third year, has gained considerable international recognition and popularity. Manuscripts have been received from many institutions in Thailand as well as from various countries and international organizations. During the past year, several of our staff participated in various international meetings held in Thailand and abroad; many have also presented their papers at these meetings. The Management of Assumption University is proud of their performance and achievements.

In order to keep record of their endeavors as well as to encourage other staff members to make similar contributions, all abstracts of scientific papers presented at the international scientific meetings during this one-year period from June 1998 to June 1999 have been compiled and published in a booklet form for distribution to interested individuals and institutions. It is hoped that this small publication will be of some benefit to our readers and that it will serve the dual function of giving information as well as encouragement to all our staff. It is our determination to continue this particular publication every year. On behalf of the University, I wish to express my sincere thank to Dr. Narong Chomchalow, the Editor of AU Journal of Technology, for his initiative, as well as the hard work involved in compiling, editing, and preparing the manuscripts of the AU Abstracts - 1999.
