The invention generates moving image information obtained by compositing a moving image of a user and objects selected by the user, and provides the generated moving image information to the user. A set of online data, which is available for online access, is persisted as a set of offline data in a local storage associated with a user device and a key-value pair is used to cross-reference the first set of online data and the first set of offline data, An access request for a set of data, corresponding to the first set of online data, is received from a user device application. An anchor layer is most preferably formed directly onto the glass substrate surface by means of the application of a humidified reaction product of silicon tetrachloride, followed by the vapor-deposition of MTCS as a cross-linking layer. Furthermore, the polyurethane ballast layer can keep the polyurethane foam filled in the ballasts layer away from water in the outside environment to avoid hydrolysis. The shaft has a head at one end and a nut opposite the head.
