A box formed from a single piece of punched and crease-lined cardboard sheet, the box having an inviolable security seal which is broken when the closed box is opened for the first time. The image sensor includes a semiconductor substrate, a plurality of unit pixel regions for light-conversing an incident light upon a surface of the semiconductor substrate, and a pixel isolation region positioned between the adjacent unit pixel regions. Business rules repositories can be stored separately from independent test scripts and from test data sources. A superconductive filter is provided which can shift a center frequency of a filter band and suppress disturbance of a waveform of a filter characteristic, with a simple method. The method comprises: providing a user interface for a user to input a text query relevant to a video to be retrieved; carrying out a text-based image searching based on the text query to provide a plurality of images relevant to the video; and carrying out an example-based video retrieval based on one image selected by the user from the plurality of images. The shoulder of the shoulder bolt fastener can pass between the opposed walls.
