Abstract: Disclosed are epitopes of the epidermal growth factor receptor (EGFR) and the use thereof. The epitopes are highly preserved, and located in the domain closely related to binding with an epidermal growth factor (EGF). Therefore, vaccine compositions comprising the epitopes or compositions comprising antibodies to the epitopes may efficiently block a signal transduction caused by binding of EGF and EGRF, and thus can be highly valuably used in treating various diseases such as cancer. An antibody bound to the epitopes of the present invention may efficiently inhibit binding of various EGFR ligands such as not only EGF but also TGF-?, AR, BTC, EPR and HB-EGF, with EGFR, and therefore can be used in treating various diseases resulting from an activation of EGFR caused by binding not only with EGF but also with other EGFR ligands.

Abstract: In a light ray controller, a light transmission diffusion layer and a light reflection layer are laminated on each other. The light ray controller is arranged such that the light transmission diffusion layer is located between a rotation center axis and the light reflection layer. A light ray generator emits a light ray group including a plurality of light rays towards the light transmission diffusion layer rotated by a rotation module.
