Abstract: The present invention relates to a composition for controlling insect pest comprising microencapsulation-based spray drying formulation of Btk IMBL-B9 as an active ingredient. Specifically, when a microencapsulation-based spray drying formulation was prepared targeting Btk IMBL-B9 (Bacillus thuringiensis subsp. kurstaki IMBL-B9), it improves the spore-crystal complex stability to increase the spore survival rate and enhance the storage stability as compared with the non-encapsulated spray drying formulation. In addition, the encapsulated spray drying formulation of Btk IMBL-B9 was verified to have excellent insecticidal activity against Spodoptera frugiperda and Plutella xylostella, and can be used more effectively to prevent or control the insect pests.

Abstract: Provided is a decoding apparatus and method based on a variable error correction value. The decoding method includes setting an initial normalized factor and a normalized factor correction value, initially updating a check node based on the initial normalized factor, and updating the check node based on a variable error correction value acquired by adding the initial normalized factor and the normalized factor correction value.

Abstract: Provided is an apparatus and method for transmitting/receiving multiband broadcasting using scalable video coding, which can solve a limitation of a transmission band in a multichannel satellite broadcasting service and increase availability of a satellite broadcasting service by scalably encoding video data and transmitting the data using a different transmission band for each layer. The apparatus for transmitting multiband broadcasting using scalable video coding includes: a scalable video encoder for scalably encoding video data to generate a scalable video stream having multiple layers; a multiplexer for multiplexing the scalable video elementary stream having multiple layers, a compressed audio elementary stream, and program specification information to generate a transport stream (TS); and a multiband transmitter for separating packets of the TS into multiple TSs according to pre-given priority information and transmitting the packet streams using a different transmission band.

Abstract: Provided are a preprocessing apparatus and a method thereof for group-based decoding. The preprocessing apparatus includes a log likelihood ratio (LLR) calculator for calculating LLRs of received signals, a signal sorter for sorting the received signals based on the calculated LLRs; and a grouping unit for grouping the sorted signals.
