  • Patent number: 11006313
    Abstract: A pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system, such as Long-Term Evolution (LTE) is provided. An apparatus for providing a service network in a wireless communication system is provided. The apparatus includes a first transceiver configured to support a first radio access technology (RAT), a second transceiver configured to support a second RAT, and at least one processor configured to access a base station using the first RAT, provide a service network to at least one client device using the second RAT, and transmit at least one signal to restrict the at least one client device from entering a power saving mode, if a traffic of a client device is transferred via a low-latency service provided in the first RAT.

  • Patent number: 9433607
    Abstract: The present invention relates to ethyl(2-methyl-3{(E)-[(naphtho[2,1-b]furan-2-ylcarbonyl)hydrazono]methyl}-1H-indole-1-yl)acetate, the novel mitosis inhibitor. The said ethyl(2-methyl-3{(E)-[(naphtho[2,1-b]furan-2-ylcarbonyl)hydrazono]methyl}-1H-indole-1-yl)acetate not only induces apoptosis by inhibiting tubulin polymerization in the course of mitosis but also displays an excellent anticancer effect in the multi-drug resistant cancer cells, so that it can be effectively used for the treatment of cell proliferative disease including various cancers.
