Abstract: An acute kidney injury predicting system and a method thereof are proposed. A processor reads the data to be tested, the detection data, the machine learning algorithm and the risk probability comparison table from a main memory. The processor trains the detection data according to the machine learning algorithm to generate an acute kidney injury prediction model, and inputs the data to be tested into the acute kidney injury prediction model to generate an acute kidney injury characteristic risk probability and a data sequence table. The data sequence table lists the data to be tested in sequence according to a proportion of each of the data to be tested in the acute kidney injury characteristics. The processor selects one of the medical treatment data from the risk probability comparison table according to the acute kidney injury characteristic risk probability.

Abstract: A milling cutter is used for processing a metal substrate and includes a handle and a cutting portion. The cutting portion extends outward from one end of the handle. The cutting portion includes at least two opposite spiral guiding grooves. A cutting knifes is provided on one side of the guiding groove. The cutting knife has a spiral angle with range between 35°˜45° and the cutting portion is coated with a coating layer on surface thereof. The surface hardness, lubrication and scouring removing ability are enhanced. The abrasion and heat pipe for the cutting knifes 23 and 24 can be eliminated.

Abstract: A drilling pin for machining metal substrates includes a drillstock, a drill bit, and a coating. The drill bit extends from an end of the drillstock, and includes at least two corresponding helix guide grooves. Two knife-edges are formed/defined between the at least two helix guide grooves. A helix angle defined by an axis of the drill bit and a tangent of the two knife-edges is in a range from about 15 degrees to about 35 degrees. The coating is formed on a surface of the drill bit. Thus, strength, lubricity, scraps discharge performance of the drilling pin have been greatly improved, and abrasion and thermal budget phenomena can be decreased. Therefore, the service life of the drilling pin can be greatly extended.
