The present invention relates to an image information encoding and decoding method and a device for same. The heavy electrons absorb energy from the gamma radiation and re-radiate it as photons at a lower energy and frequency. A retard-side side surface of an engaging hole is configured so as to be able to adjust a clearance between the second limiting pin and the retard-side side surface when the first limiting pin is engaged with a first advance end portion. The middleware management service causes the middleware policy to be applied to network traffic by directing network traffic to a middleware enforcement mechanism. The user-interface device is external to the food conditioning module and disconnectably connected thereto.
