  • Publication number: 20230398167
    Abstract: The present invention relates to a composition for exterminating fish parasites comprising an extract of Juglans mandshurica bark as an active ingredient, making it possible to safely and effectively exterminate scuticociliates using an extract derived from a natural material, instead of formalin that is highly harmful, which has been conventionally used to treat scuticociliatosis in fish.

  • Patent number: 10745732
    Abstract: The present disclosure relates to genetic markers for discrimination and detection of bacteria causing Edwardsiellosis and Streptococcosis in fish, and a method for discriminating and detecting the bacteria using the same. A genetic marker for discrimination and/or detection of each of Edwardsiella tarda, Streptococcus iniae, Streptococcus parauberis and Lactococcus garvieae, which cause fish diseases, is selected and a peptide nucleic acid and a primer pair, which are specific for the genetic marker, are used to amplify and obtain melting curves having different fluorescences depending on bacterial species. Thus, bacteria that cause fish diseases can be discriminated and whether or not fish would be infected with the bacteria can be detected in a simple, rapid and accurate manner.

  • Patent number: 8213985
    Abstract: A mobile communication terminal supporting a teletypewriter (TTY) device for a hard-of-hearing or speech-disabled user is provided. The mobile communication terminal includes: a controller activating a vocoder corresponding to a TTY mode selected by a user; a vocoder encoding a Baudot tone received from the TTY device into a voice data packet based on the selected TTY mode; a TTY mode processor including TTY mode information selected by a user in part of the voice data packet; and an RF transmitter transmitting an encoded voice data packet including the TTY mode information.
