Abstract: The present disclosure relates to a method for providing whether a patient is accompanied by a caregiver and a device using the same, the method for providing whether the patient is accompanied by the caregiver being configured to be implemented by a processor and including receiving an outpatient clinic record from a user device, tokenizing each sentence of the outpatient clinic record as a unit of at least one token, encoding the tokenized outpatient clinic record as an integer, and determining whether a psychiatric symptom occurs for a patient related to the outpatient clinic record by inputting the encoded outpatient clinic record by using a determination model that uses the encoded outpatient clinic record as an input and uses whether the psychiatric symptom occurs as an output.

Abstract: A lead-free soldering material for soldering wires of electronic parts is disclosed. The lead-free soldering material is composed of in weight %: 3-4% of Ag, 2-5% of In, 6-14% of Bi and a balance of Sn, and the soldering material shows a superior solderability.

Abstract: A tungsten based heavy alloy having a W--Ni--Fe based composition containing traces of lanthanum or calcium, thereby capable of exhibiting high toughness, irrespective of the content of impurities such as phosphorous and sulfur contained therein, the cooling rate after the sintering treatment and the re-heating treatment. The present invention provides a method for making the high toughness tungsten based heavy alloy. The tungsten based heavy alloy of the present invention is useful to manufacture warheads for breaking armor plates, which require high toughness.
