Golomb의 공리를 이용한 Shrinking Generator의 분석
김정헌,권기호,박명진 한국군사과학기술학회 2001 한국군사과학기술학회지 Vol.4 No.2
The shrinking generator is simple and stateable, and known that has good security properties. The bits of one output( $R_1$) are used to determine whether the corresponding bits of the second output will be used as part of the overall keystream. Two LFSRs consisting the generator generate pseudorandom sequences satisfying Golomb's postulates. We used this property to analyze the stream of LFSR $R_1$ of the generator.
보중익기탕(補中益氣湯), 인삼(人蔘) 및 황(黃)기 약침(藥鍼)이 MTX로 약침(誘發)된 백서(白鼠)의 면역기능저하(免疫機能低下)에 미치는 영향(影響)

Objectives : To investigate the effects of herb-acupunctures of Qi tonification herbs or formula on the rat immune depression induced by an anticancer drug, methotrexate (MTX) Methods: Animals were divided into 5 groups; Normal control group was not given any treatment. Immune depression was induced by oral administration of 1mg/kg MTX b.i.d for 4 days in Control, Sample I, II, and III groups. We treated on CV 4 (Guanyuan) with saline, Bojoongiggi-tang (Buzhongyiqi-tang), Ginseng Radix and Astragali Radix herb-acupunctures in Control, Sample I, II, and Ill groups, respectively. In both blood and spleen, the assessment of CD4+ T-cell count, CD8+ T-cell count, CD4/CD8 T-cell ratio was performed. Results: Here we show that 3 herb- acupuncture groups have an influence, to some extent, on CD4+ and CD8+ T-cell counts and CD4/CD8 T-cell ratio in both blood and spleen. Astragali Radix herb-acupuncture, in particular, was found to have significantly increased CD4+ T-cell count in blood and CD4/CD8 T-cell ratio in blood and spleen. Conclusions: The results of this study suggest that herb-acupunctures of Bojoongiggi-tang (Buzhongyiqi-tang), Ginseng Radix and Astragali Radix may have an influence over rat immune depression induced by MTX.
