On behalf of the Korean Society of Obstetrics and Gynecology, I am pleased that lots of celebrated professors and promising young doctors would share valuable time at the 19th Seoul International Symposium held in Seoul, Korea on Sept. 27, 2014. We are going to discuss various parts of obstetrics and gynecology which are gynecologic oncology, reproductive endocrinology, maternal-fetal medicine and general gynecology. Therefore, this congress will be a great opportunity to confer about currently concerned issues in obstetrics and gynecology and find reasonable solution. The scientific program is consisted of diverse presentations by the distinguished speakers with up-to-date topics on both basic and clinical fields to enhance our medical status. In addition, in this year, both Prof. Noriaki Sakuragi from Japan and Prof. Ching-Hung Hsieh from Taiwan who are plenary speakers will be new Honorary members of KSOG. I hope that all of participants would enjoy and share scientific information. I wish to have a wonderful memory in Korea.
