Because in this internship program we need to use English for communicating. Then, I thought that this would be a great chance to improve English skills. I used to be an exchange student in Konkuk University, Korea for a semester. I have learnt about culture and Korean language it’s a good opportunity. So, I wanted to learn about culture of Japan that how it would be different from Thailand and Korean. During study in sophomore I had an experience to do the project about using liner algebra to apply in daily life.
