I am a Ceo of Korea Education System and a brand marketing professor of Sungkyunkwan Business School in Korea. I have invented some toys (Co-Block, Corecar, etc) for children. I got an award of Service Marketing Association with the paper (The Effect of Children’s Toy Attachment on Brand Supporting Behavior and Psychological Well-Being by Mediation of Self-Efficacy). I have studied toy attachment and self-efficacy especially social efficacy for children during 15 years.
