A nanoenergetic material composite having a remote ignition characteristic by a high-power pulsed laser beam is prepared by adding various contents of multiwalled carbon nanotubes (MWCNTs) to a nanoenergetic composite material (nEM) to enable remote ignition by a high-power laser beam. The nanoenergetic material composite is a MWCNT/nEM composite powder prepared by adding multiwalled carbon nanotubes to the nanoenergetic material, which is a mixture of fuel material nanoparticles and metal oxidizer nanoparticles, wherein the multiwalled carbon nanotubes enhance a combustion rate of the MWCNT/nEM composite powder by delivering thermal energy upon remote optical ignition by the high-power pulsed laser beam.

The present invention relates to a motor driving apparatus and a home appliance including the same. A motor driving apparatus according to an embodiment of the present invention includes an inverter for converting a DC voltage of a DC-link capacitor into an AC voltage according to a switching operation and outputting the converted AC voltage to a motor; a DC-link resistor disposed between the DC-link capacitor and the inverter; and a controller for controlling the inverter based on a phase current sampled through the DC-link resistor, wherein the controller estimates a phase current based on the phase current sampled through the DC link resistor, in an interval in which phase current detection is not possible. Thereby, the phase current flowing through the motor may be accurately calculated using the DC link resistor.

The present invention relates to a nitrogen oxide-releasing wound treatment film and a preparation method therefor. A nitrogen oxide-releasing film containing S-nitroglutathione, which is a nitrogen oxide donor to be spontaneously formed in the human body, has mechanical characteristics enabled to be applied to the human body, slowly releases nitrogen oxide and inhibits a pathogen, which is the main cause of wound infection, and can quickly heal a wound, and thus the film can be useful for treating a wound.


Disclosed is a new compound that inhibits binding between a DX2 protein and a p14/ARF protein, a pharmaceutical composition including the new compound as an effective component for treating or preventing a cancer disease, an anticancer adjuvant for improving an anticancer effect of a drug-resistant anticancer drug, and a composition including an AIMP2-DX2 protein or a fragment thereof for diagnosing lung cancer.


The present invention relates to a new compound for inhibiting binding between a DX2 protein and a p14/ARF protein, and a medical use thereof. A review of the in vitro and in vivo anticancer effect of the compound shows that the compound has an excellent anticancer effect and thus is useful as a drug for treating various cancer diseases including lung cancer, and has a more improved anticancer effect particularly by inhibiting resistance to an anticancer drug of Adriamycin in a cell line which is resistant to an anticancer drug such as Adriamycin, and thus can be used as an anticancer adjuvant for improving the anticancer effect. In addition, the present invention relates to a composition for diagnosing lung cancer comprising an AIMP2-DX2 protein or a fragment thereof, and is effective in diagnosis of lung cancer because whether or not a subject has lung cancer is confirmed only by using a serum sample of the subject.


Provided are an apparatus and method for classifying home appliances based on power consumption using deep learning, which can efficiently classify home appliances in use by applying deep learning and analyzing power data collected from a house. The apparatus includes a home appliance classification model creation module configured to encode power consumption data collected from a house to learn a home appliance classification model and create an RNN-based home appliance classification model and a home appliance classification module configured to collect and encode data on power consumption currently in use and classify home appliances using the home appliance classification model created by the home appliance classification model creation module.


Provided are an electronic device including a novel structured interface material capable of improving interface properties of the electronic device, and the novel interface material, and more specifically, an electronic device including the interface material of the present disclosure to allow easy extraction and injection of electrons, thereby exhibiting excellent interface properties, and a phosphine oxide functionalized triazine derivative having a structure in which an electron acceptor phosphine oxide group is substituted in 1,3,5-triazine-based skeleton, which is the interface material.


A manufacturing method of a semiconductor device includes forming a hard mask layer on a semiconductor substrate using a hard mask composition. Hard mask patterns are formed by patterning the hard mask layer. Semiconductor patterns are formed by etching the semiconductor substrate using the hard mask patterns. The hard mask composition includes a plurality of first carbon nanotubes (CNTs) having a first length, a plurality of second CNTs having a second length, which is at least 3 times the first length, and a dispersing agent in which the first CNTs and the second CNTs are dispersed. The total mass of the first CNTs is 1 to 2.5 times the total mass of the second CNTs.

The present invention relates to a method for manufacturing an ultrafine single-crystalline metal wire. The method continuously manufactures an ultrafine long single-crystalline wire by shaping a grown single-crystalline metal to have a circular or rectangular cross section and then by drawing the shape-processed single-crystalline metal using a drawing machine. Therefore, the method simplifies manufacturing procedures to reduce manufacturing costs and lowers electrical resistance of a produced metal wire to improve the quality of the produced metal wire. The method comprises: a first step of growing a single-crystalline metal ingot using a Czochralski or a Bridgman method; a second step of subjecting the single-crystalline metal ingot to a shaping process such that the single-crystalline metal ingot has a certain shape; and a third step of completing the manufacture of an ultrafine single-crystalline metal wire by drawing the shape-processed single-crystalline metal.
