Hyung-Suk Han received the Ph.D. degree inmechanical engineering from Ajou University in 1997. He is the head ofDepartment of Magnetic Levitation and Linear Drive at Korea Institute ofMachinery & Materials. He has worked extensively in maglev which includes the urban maglev ECOBEE andexperimental maglev vehicle SUMA for high speed. His research interests aredynamics simulation, magnetic levitation control and certification of maglevvehicle performances. He has been attempting to apply maglev technology to newapplications such as clean conveyor and amusement rides.Dong-Sung Kim received B.S. in Mechanics andDesign from Seoul National University and M.S. in Mechanical Engineering fromChangwon National University, and Dr-Ing. in Mechanical Engineering from EcoleCentrale de Nantes in 1996. For 8 years since 1997, he carried out NationalResearch Projects of a developing low-medium speed urban maglev vehicle, as theHead ofVehicle Engineering Group in New Transport Technology Department atKorea Institute of Machinery and Materials. In 2006, he was a core projectmanager of Systems Engineering in the Urban Maglev (ECOBEE) Program funded byKorean Government. He currently continues to try to promote a commercializationand application of the urban maglev system.
