Abstract:
Disclosed is a method for evaluating Internet contents created by users through an automatic analysis and output and recording media for storing a program implementing the same. The method includes inputting location information of Internet contents to be evaluated; automatically extracting predetermined evaluation factors from the Internet contents corresponding to the inputted location information; evaluating the Internet contents by substituting the extracted evaluation factors into a predetermined algorithm; and outputting evaluation information. Furthermore, a database for the corresponding contents, which is obtained based on the extracted evaluation factors and the information inputted by the user, enables a systematic provision for evaluation and ranking of the contents.

A developing unit and an electro-photographic image forming apparatus having the same are provided. The developing unit includes a housing and a photosensitive medium, which has an end exposed to the outer side of the housing and that is rotatably mounted on the housing. A photosensitive medium shutter shields the exposed part of the photosensitive medium when a door is opened and exposes the exposed part of the photosensitive medium to the outside when the door is closed. The photosensitive medium shutter includes a first shielding plate that is moved between a first location where the exposed part is shielded and a second location where the exposed part is exposed to the outside of the housing. A second shielding plate is spread at the first location with respect to the first shielding plate and is overlapped with the first shielding plate at the second location.
Abstract:
Disclosed is a method for forming a polycrystalline silicon film by crystallizing an amorphous silicon film. A mask has first to third shot regions having the same length. The first to third shot regions have transmission sections and non-transmission sections, which are alternately aligned. The transmission sections of the first shot region are positioned corresponding to the non-transmission sections of the second shot region, the non-transmission sections of the first shot region are positioned corresponding to the transmission sections of the second shot region, and the transmission sections of the third shot region are aligned corresponding to center portions of the transmission sections of the first and second shot regions. Primary to nth laser irradiation processes are performed with respect to the glass substrate, thereby crystallizing the amorphous silicon film into the polycrystalline silicon film.
Abstract:
A waste toner collecting apparatus separates waste toner remaining on an outer circumferential surface of a photosensitive medium when a visible image is transferred thereon and stores the separated waste toner. An electrophotographic image forming device includes the waste toner collecting apparatus. The waste toner collecting apparatus includes a cleaning blade that separates the waste toner from a photosensitive medium by scratching the outer circumferential surface of the photosensitive medium. A waste toner container stores the waste toner. The waste toner separated from the photosensitive medium is transported to the waste toner container through a waste toner passage. An agitating plate reciprocates inside the waste toner passage to prevent accumulation of the waste toner.
