Abstract: A method of predicting pressure ulcers is provided. The method includes predicting, by a first pressure ulcer predictor, occurrence of pressure ulcers of a patient to output first prediction result data, based on body data of the patient, predicting, by a second pressure ulcer predictor, occurrence of pressure ulcers of the patient to output second prediction result data, based on whole body pressure data of the patient, predicting, by a third pressure ulcer predictor, occurrence of pressure ulcers of the patient to output third prediction result data, based on skin image data of the patient, and concatenating the first to third prediction result data to output final prediction result data.

Abstract: A power-line communication system and control method to supply power and data to an Integrated Service Digital Network (ISDN) subscriber terminal includes: a subscriber terminal adapted to transmit a response message upon a connection request message being received; and a power supply switch adapted to transmit the connection request message to the subscriber terminal, and to supply power together with data to the subscriber terminal upon the response message to the connection request message being received from the subscriber terminal. The power supply switch is adapted to cut off the power supplied to the subscriber terminal upon the response message to the connection request message not being received from the subscriber terminal.

Abstract: A method of ordering a variety of diversified products over the Internet from a central bureau carrying no inventories and making no deliveries but interacting with diversely located and pre-existing satellite member retailers carrying the inventories and making the deliveries so as to establish a pre-arranged network of member retailers now having an opportunity to compete with Internet retailers. A consumer orders a product over the Internet from the interactive website of the central bureau to be delivered to a specific destination. The central bureau locates the member retailer most closest to the specific destination and delegates the order thereto to be filled and delivered to the specific destination.
