A catalyst filling method in a micro channel and a reformer manufactured by the method. The catalyst is filled in the micro channel using water, and unidirectional pressure is applied to the catalyst in the micro channel to fill the micro channel with high density. The catalyst in the micro channel is dried. The method according to the present invention allows uniformly filling the catalyst particles in the micro channel of the reformer with high density, increasing the reactive surface area of the catalyst particles with the fuel, thereby allowing highly efficient reforming effect.

A system and method for processing postal work using Radio Frequency Identification (RFID) apparatus. With RFID applied to the postal work, the system includes a structure for managing postal devices used in postal registration center and postal delivery center such as embedded controllers for controlling monitors, audio alarms, alarm lamps and PDAs. The system also includes middleware for managing RFID readers and message repeater adopting Java Messaging Service (JMS) . This allows exchanging data received from the RFID reader by JMS transfer method, ensuring stable asynchronous exchange of information and effective monitoring of data transferred in an entire process of postal work. This also decreases the load of the middleware in a work environment where a large amount of data is received in a short period of time such as postal work process.

The present invention relates to a photosensitive composition comprising a triazine-based photoactive compound containing oxime ester. The photosensitive composition according to the present invention has good sensitivity, retention rate, mechanical strength, heat resistance, chemical resistance and developing durability since it contains, as photopolymerization initiator, a compound having an oxime ester group and a triazine group in one molecule and thus effectively absorbs UV radiation. Therefore, the photosensitive composition according to the present invention is advantageous not only in curing of materials for color filters, resin black matrixes, column spacers, overcoats and passivation films of liquid crystal displays, but also in high temperature process characteristics.
