FFT(Fast Fourier Transform) 알고리즘에는 DIT(Decimation-In-Time)와 DIF(Decimation-In-Frequency)가 있다. DIF 알고리즘은 Radix-2/4/8 등의 다양한 종류와 그 구현 방법이 개발되어 사용되고 잇으나, DIT 알고리즘은 순차적인 출력을 낼 수 있는 장점이 있음에도 불구하고 다양한 알고리즘이 연구되지 못하였다. 이 논문에서는 새로운 DIT Radix-4 FFT의 나비연산기(butterfly) 구조를 제안하고 검증하였다. 제안 구조를 사용하여 64-point FFT 구조를 설계하고 Verilog로 코딩하여 구현함으로써 제안 구조의 효용성을 입증하였다. 48개의 곱셈기를 사용하여 합성하였으며 678만 게이트 수를 나타내었다. 따라서 제안된 DIT Radix-4 FFT 구조는 순차적인 FFT 출력을 필요로 하는 OFDM 통신용 SoC(System on a Chip)에 사용될 수 있을 것이다.

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.

Recently many efforts were focused to understand the mechanical insights of melanogenesis to develop the agents for hyper-pigmentation and hypo-pigmentation. In the melanin biosynthetic pathway, tyrosinase is the rate limiting enzyme, and ${\alpha}$-melanocyte stimulating hormone(MSH) or cAMP-elevating agents stimulate melanogenesis and enhance the melanin synthesis and the tyrosinase activity. The author has analyzed the effects of Radix Trichosanthis on the basal melanogenic activities of B16/F10 mouse melanoma cells, and on the ${\alpha}$-MSH or forskolin-induced melanogenesis. Radix Trichosanthis alone markedly suppressed melanin content and tyrosinase activity in a dose-dependent manner. Pretreatment of the cells with Radix Trichosanthis also suppressed the increase of ${\alpha}$-MSH (10 nM) or forskolin (20${\mu}M$)-induced melanin content and tyrosinase activity. The decrease in the tyrosinase activity was paralled by a decrease in the abundance of tyrosinase protein and tyrosinase promoter activity. Pretreatment of the cells with Radix Trichosanthis also inhibited the increase of forskolin($20{\mu}M$) induced the amount of tyrosinase protein and tyrosinase promoter activity. The results of DOPA staining revealed that pretreatment of the cells with Radix Trichosanthis showed less intensity than B16 melanoma cells stimulated with ${\alpha}$- MSH or forskolin. These results suggest that Radix Trichosanthis inhibits melanogenesis and abrogates ${\alpha}-MSH and cAMP-induced melanogenesis in B16 melanoma cells.

To study the effects of anti-cancer, anti-metastasis and immune response improvement of herbal-acupuncture with Aucklandiae Radix diffusae herba infusion solution(AKL-HAS), we injected AKL-HAS into Zusanli(St36) of C57BL/6 mice implanted intravenously with B16-F10 melanoma. The results were obtained as follows : 1. In the experiment groups treated with Aucklandiae Radix(AKL) Herbal-Acupuncture, the spleen cell proliferation in Balb/c mouse was significantly increased compared with that of the control group. 2. In the experiment groups treated with Aucklandiae Radix(AKL) Herbal-Acupuncture, the percentage of $CD25^{+}/CD4^{+},\;CD8^{+}/CD3e^{+},\;CD69^{+}/B220^{+},\;NK1.1^{+}/CD3e^{+}$ cells in C57BL/6 mouse PBMCs was increased compared with that of the control group. 3. In the experiment groups treated with Aucklandiae Radix(AKL) Herbal-Acupuncture, the pulmonary colony number of C57BL/6 mice implanted intravenously with B16-F10 melanoma was decreased significantly compared with that of the control group. 4.

This paper presents the design of a low-power, low area 256-radix 16-bit crossbar switch employing a 2D Hyper-X network topology. The Hyper-X crossbar switch realizes the high radix of 256 by hierarchically combining a set of 4-radix sub-switches and applies three modifications to the basic Hyper-X topology in order to mitigate the adverse scaling of power consumption and propagation delay with the increasing radix. For instance, by restricting the directions in which signals can be routed, by restricting the ports to which signals can be connected, and by replacing the column-wise routes with diagonal routes, the fanout of each circuit node can be substantially reduced from 256 to 4~8. The proposed 256-radix, 16-bit crossbar switch is designed in a 65 nm CMOS and occupies the total area of $0.93{\times}1.25mm^2$. The simulated worst-case delay and power dissipation are 641 ps and 13.01 W when operating at a 1.2 V supply and 1 GHz frequency. In comparison with the state-of-the-art designs, the proposed crossbar switch design achieves the best energy-delay efficiency of $2.203cycle/ns{\cdot}fJ{\cdot}{\lambda}2$.
