Mr. Hwang,

Good day! I'm Sofia Marah P. Frias, a student of the University of the Philippines Diliman. I am currently conducting my research on multiple image formation and I found your java applet very useful and interesting. I would just like to request for your approval or consent so I could include your java applet as one of my references in my research.

Thank you for your time and I would be patiently waiting for your reply.

Sofia Marah Frias
