Abstract: A method for assaying kasugamycin is provided to analyze kasugamycin in a greater quantity of sample simply and rapidly even without any pre-treatment or assistant analyzing device. A method for assaying kasugamycin comprises analysis of kasugamycin in an agricultural chemical product by using HPLC(High Performance Liquid Chromatography), wherein the method comprises the steps of: (1) extracting kasugamycin from an agricultural chemical product; (2) adding thereto an internal reference material; (3) injecting the extracted sample into a column for HPLC; (4) flowing a mobile phase through the column so that the kasugamycin is eluted; and (5) analyzing the eluted kasugamycin with an ultraviolet detector. In the method, pyridoxal 5-phosphate is employed as the internal reference material.

Abstract: PURPOSE: A method for restoring a received signal is provided to improve a performance restoring a transmitted signal in a receiver by lowering a bit error rate. CONSTITUTION: A receiver estimates a channel coefficient by receiving a signal transmitted from a multiuser receiver(S110). A basic signal estimation value corresponding to a LLR which is estimated signal transmitted from k-th transmitter is acquired(S120). A signal reestimation value corresponding to a LLR which is estimated by a signal transmitted from k-th transmitter is acquired by considering a forward error correction based on a basic signal estimation value. Those processes are repeated as the times predefined(S140). A signal transmitted from the k-th transmitter is restored from the reestimation value(S150).
Abstract translation: 目的：提供一种恢复接收信号的方法，以通过降低误码率来改善接收机中发射信号的恢复性能。 构成：接收器通过接收从多用户接收器发送的信号来估计信道系数（S110）。 获取与从第k个发送机发送的估计信号的LLR对应的基本信号估计值（S120）。 通过考虑基于基本信号估计值的前向纠错来获取与由第k个发送机发送的信号估计的LLR对应的信号重新估计值。 这些处理被重复为预定义的时间（S140）。 从第k个发射机发送的信号从重新估计值恢复（S150）。

Abstract: 본 발명은 고성능 액체크로마토그래피(HPLC)를 이용하여 살균제 중 가스가마이신을 분석하는 방법에 관한 것이다.
종래에는 가스가마이신을 분석하는 방법으로서 박테리아를 이용한 생물검정법이 이용되었으나 장기간을 요하고, 재현성이 떨어지며, 대량의 시료를 분석할 수 없는 단점이 있었다.
본 발명은 불순물을 제거하는 전처리나, 보조분석기기를 사용하지 않고 간단한 추출 후 바로 시료를 고성능 액체크로마토그래피에 주입하여 가스가마이신을 분석함을 특징으로 하고 있어 간편하고 신속하게 대량의 시료에서 가스가마이신을 분석할 수 있도록 하는 효과가 있다.
