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 seawater pre-treatment method is provided that includes: installing a filtration filter in the form of a hollow cylinder at a predetermined depth of a sea floor, installing a water collection pipe in which a plurality of openings are formed in the inner part of the filtration filter, the water collection pipe being in fluid communication with a water collection tank, sucking pre-treated water from the inner part of the water collection tank by a water conveying pump, and passing the seawater through the filtration filter by a reverse osmosis method and flowing into the water collection pipe and the water collection tank.

Abstract: Disclosed are an apparatus and method for the seawater pre-treatment to remove salt from seawater. The seawater pre-treatment apparatus for desalinating seawater into fresh water comprises: a seawater pre-treatment unit, located at a predetermined depth of a sea floor, for obtaining a pre-treated water by removing impurities from the seawater; a pre-treatment water tank, located on the ground, for accommodating the pre-treatment water tank produced by the pre-treatment unit; and a connection flow channel for connecting the pre-treatment unit and the pre-treatment water tank such that the pre-treated water can be transported. The seawater pre-treatment apparatus and method are capable of simplifying the configuration of the entire apparatus while reducing the consumption of energy during the pre-treatment process for the seawater desalination.
