  • Publication number: 20190182515
    Abstract: Disclosed herein are an apparatus and method for providing a broadcasting service. The method for providing a broadcasting service is performed using a broadcasting service provision apparatus and a terminal device, and includes performing, by the broadcasting service provision apparatus and the terminal device, initialization using information acquired from a downstream signal received from a Cable Modem Termination System (CMTS), converting, by the terminal device, an upstream signal received from a Cable Modem (CM) into a digital signal, encapsulating the digital signal into an IP packet, and transmitting the IP packet to the broadcasting service provision apparatus, and extracting, by the broadcasting service provision apparatus, the digital signal from the IP packet received from the terminal device, converting the digital signal into an analog signal, and transmitting an upstream signal corresponding to the analog signal to the CMTS.

  • Publication number: 20190151391
    Abstract: The present invention relates to a composition for an inflammatory disease, using Litsea japonica, and more specifically to a composition for preventing and treating an inflammatory disease, containing the oil derived from the fruits or the seeds of Litsea japonica, and a method for preparing the same. The present invention uses the fruits (excluding the seeds) or the seeds of Litsea japonica and obtains the oil, which is used as an active ingredient of a composition for preventing and treating an inflammatory disease, by using n-hexane, wherein the oil is obtained by: separating the fruits (excluding the seeds) of Litsea japonica from the seeds; injecting n-hexane, which is a solvent, into the fruits (excluding the seeds) or the seeds, 9-11 times greater than the weight of each: stirring the same for 24 hours at room temperature and extracting the same; and removing a hexane layer.
