Abstract: Disclosed is a method and system for automatic establishment of an optimal schedule for a construction project. The disclosed method of automatic establishment of an optimal schedule for a construction project is a computer-implemented method of automatic establishment of an optimal schedule for a construction project, the method including: providing project data, standardized schedule data, and characteristic data (S10); generating project schedule data by combining the project data, the standardized schedule data, and the characteristic data (S20); and deriving an optimal project schedule by processing the project schedule data through a scheduling optimization algorithm (S30).

Abstract: The present application provides a method and system which provide a virtual stock exchange service. In one particular implementation, the system includes a resource locator database, a resource locator search server, a listed resource domain database, a user database, and a virtual stock trading management server. The resource locator database includes search information for a resource domain forming a search pool. The search information includes a search score assigned to the resource domain and one or more resource locators associated with the resource domain. The resource locator search server searches the resource locator database and transmits a result list of the search in response to a user's query. The listed resource domain database includes information of the resource domain categorized as a listed resource domain or a listing candidate resource domain according to the search score of the resource domain.

Abstract: An apparatus for controlling a door using a mobile radio communication system is disclosed, in which the door of an apartment, a building, an automobile, a traveller's bag, a parking lot or the like can be automatically unlocked by using a mobile radio communication terminal at a remote place. The apparatus for controlling a door using a mobile radio communication system includes a transmitting device for generating control signals for unlocking the door, the door having an automatic locking device equipped with a receiving device for receiving wireless signals. It further includes a mobile radio communication terminal which can be connected through a wire to the transmitting device, for converting the control signals, the door unlocking signals, generated in the transmitting device into wireless signals for delivery. The wireless signals for unlocking the door are received by the receiving device installed in the door locking device for the door to be unlocked automatically.
