  • The Polygoni Radix and Cynanchi Radix have been used to potentiate the liver functions in clinic of Oriental Medicine. The water extracts of Polygoni Radix and Cynanchi Radix were administered orally to rats intoxicated with carbon tetrachloride and then this experiment have been performed by observing liver fatty degeneration and activities of enzymes such as cytochrome oxidase (CYO), adenosine triphosphatase (ATP), acid phosphatase (ACP), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP). By oral administration of water extracts of the radices between 1 and 10 days, the following results were obtained. 1. The group given Cynanchi Radix extract showed recovery of the fat liver in 4 days, whereas that given Polygoni Radix extract did the recovery in 8 days. 2. In cytochrome oxidase activity, the group given Cynanchi extract showed normal activity in 6 days, whereas that given Polygoni Radix extract did the activity in 8 days. 3. In adenosine triphosphatase activity, the groups given Cynanchi Radix and Polygoni Radix extracts showed normal activities in 2 and 8 days, respectively. 4. In acid phosphatase activity, the groups given Cynanchi Radix and Polygoni Radix extracts showed recovery of the activities in 2 and 4 days, respectively. 5. In lactate dehydrogenase activity, the group given Cynanchi Radix and Polygoni Radix extracts showed recovery of the activities in 6 and 10 days, respectively. 6. In alkaline phosphatase activity, the group given Cynanchi Radix extract showed normal activity in 2 days, whereas that given Polygoni Radix extract showed slight recovery between 4 and 6 days followed by decrease of the activity in 8 and 10 days. From the above-mentioned results, it was found that both of the water extracts of Polygoni and Cynanchi Radix possessed the recovery action of liver function as intoxicated with carbon tetrachloride in rats. It is also noted that the extract of Cynanchi Radix showed more potent activity than that of Polygoni Radix.

  • 터보부호의 복호기는 두 개이상의 연판정 입출력이 가능한 복호기로 구성되며, 이러한 복호기는 일정길이의 비트열에서 최적의 사후확률(a posteriori robability)을 이용한 MAP(maximum-a-posteriori) symbol estimator를 이용한다. 기존의 radix-2 MAP복호기는 아주 큰 인터리버 블록 크기로 인해 고속 통신시스템의 적용에는 문제점이 있다. 따라서 본 논문에서는 인터리버 블록크기를 줄일 수 있는 radix-2 MAP복호기를 기바으로 하는 새로운 radix-4 MAP복호기를 제안하였다. Radix-4 MAP 복호기 구조에 적용하기 위해 순방향, 역방향 state metric과 채널 metric을 제안하였으며, 가우시안 채널에서 기존의 radix-2 기반의 MAP 복호기와 성능을 비교하였다.

  • 본 논문에서는 Radix-$2^k$ 모듈라 곱셈 알고리즘 기반의 고속 RSA 지수승 연산기의 구현 방법을 제시하고 검증하였다. Radix-$2^k$ 모듈라 곱셈 알고리즘을 구현하기 위해 Booth receding 연산 알고리즘을 사용하였으며 최대 radix-16 연산을 위해 2K-byte 메모리와 2개의 전가산기와 3개의 반가산기의 지연을 갖는 CSA(carry-save adder) 어레이를 사용하였다. CSA 어레이 출력인 캐리와 합을 고속으로 가산하기 위해 마지막 덧셈기로써 캐리 발생과 지연시간이 짧은 가상 캐리 예측 덧셈기(pseudo carry look-ahead adder)를 적용하였다. 또한, 주어진 공정에서 동작 주파수와 처리량의 관계를 통해 Radix-$2^k$에서 설계 가능한 radix 값을 제시하였다. Altera FPGA EP2K1500E를 사용하여 기능을 검증한 후 삼성 0.35$\mu\textrm{m}$ 공정을 사용하여 타이밍 시뮬레이션을 하였으며 radix-16 모듈라 곱셈 알고리즘을 사용할 경우 모듈라 곱셈에 (n+4+1)14 의 클럭을 사용하여 1,024-bit RSA를 처리하는데 50MHz에서 5.38ms의 연산 속도를 측정하였다.

  • 이 논문에서는 고속 FFT 구현을 위한 Radix-8 구조를 제안한다. 제안 FFT 구조의 핵심은 Radix-8 DIF(Decimation In Frequency) 나비연산기 구조이다. Radix-8 알고리즘은 고속처리는 가능하나 구현면적이 증가하는 단점이 있는데, 제안 구조는 곱셈연산을 DA(Distributed Arithmetic) 방식을 사용하여 구현함으로써 구현 면적이 증가하는 것을 줄일 수 있었다. 64-point FFT에 대하여 기존의 Radix-4 나비연산기와 제안된 Radix-8 나비연산기를 각각 사용하여 구현한 결과 구현면적이 49.2%가 증가하였다. 즉, Throughput을 2배로 증가시키기 위하여 하드웨어는 49.2%만 증가함을 Verilog-HDL 코딩을 통하여 확인하였다. 또한 기존 구조와 제안 구조가 같은 Throughput을 얻는 경우에는 전력소모가 25.4%가 감소하게 된다. 따라서 제안된 나비연산기를 사용하는 FFT 구조는 고속/저전력 FFT를 필요로하는 OFDM용 통신단말기에 사용될 수 있다.

  • 고속푸리에변환(Fast Fourier Transform)은 이산푸리에변환(Discrete Fourier Transform)의 주기적으로 반복되는 연산을 생략하여 그 속도를 향상시킨 연산방법이다. Radix-2 FFT는 그 정의에 따라 함수 재귀호출에 의해 구현될 수 있는데 이 방법은 스택복사 과정의 시간소모 때문에 고속동작이 어렵게 된다. 이를 극복하기 위해 신호점을 연산순서에 맞게 미리 재배열하고 배열된 신호점을 나비연산하는 방법으로 고속연산을 구현할 수 있다. 이 논문은 신호점 재배열 방법에 의한 Radix-2 FFT의 고속연산에 착안하여 Radix-3 FFT에 신호점 재배열 방식을 적용해 보고 그 타당성에 관해 고찰하였다.

  • Objectives : In order to distinguish morphological characteristics, because the inside portion of the root bark of Scutellariae Radix decomposes as time goes by, 2nd, 3rd, and 5th year Scutellariae Radix were sampled and compared according to their external, internal, and flour states through optical microscope. Methods : The slice of the tested material made by paraffin section technique was colored with Safranine Malachite Green contrast methods, and the flour of it was mounted by the liquid made by the same ratio of each of glycerin, acetic acid, and water, and then observed and photographed by olymphus-BHT. Results : 1. The inside of 2nd year Scutellariae Radix was rich and golden, the transverse section of Scutellariae Radix that was 3rd years of age was golden, but there were many Scutellariae Radix whose center portion turned redish brown, and the center portion of 5th year Scutellariae Radix had been decomposed or empty. 2. 2nd year Scutellariae Radix had the most starch grain, 5th year Scutellariae Radix had the least, and the middle portion of xylem that was 5 years of age had a cell ring that was corkish, but 2nd and 3rd year Scutellariae Radix did not have it. 3. In the flour state, 2nd, 3rd, and 5th year Scutellariae Radix did not have any difference, but the amount of starch grain was the most in 2nd year Scutellariae Radix and the least in 5th year Scutellariae Radix.
