Through the motion control experiment using Industrial Emulator(Model 220 by ECP), the performance comparison of three kinds of controllers such as PID, RIC and LQR was carried out. It was shown that RIC has the best performance in the presence of disturbances such as step one, sinusoidal one and Coulomb friction for the rigid body. LQR using feedback state variables has the best tracking performance far the flexible body. The performance of PID controller is low compared to other controllers, but the design process is simple. The most advanced controller is LQR. In order to attenuate disturbance, an additional state observer should be used to estimate it, making more complex control system. RIC lies between PID and LQR in view of complexity of design. Even though RIC is not complicated, it has good disturbance rejection ability and less tracking error. By considering these aspects, the RIC is suggested as high precision controller to be used in motion control system.

새로운 컬러 이미지 압축을 위한 Hybrid BTC(Block Truncation Coding) 알고리즘

고인성(In-sung Ko),왕준(Wang Jun),안상우,정정화(Jung-wha Chong) 대한전자공학회 2010 대한전자공학회 학술대회 Vol.2010 No.6

The authors propose a novel hybrid block truncation coding for color image compression in this paper. To improve the compression ratio of the basic BTC the proposed algorithm uses only luminance bit-map to represent the texture information of the coding block. To further compress the two representative levels an efficient previous proposed algorithm, adaptive quantization coding, is employed, moreover. Experimental results show that the proposed method provides good subject visual quality as well as the BTC does, and significantly improves the compression ratio of BTC from 2.88:1 to 6.00:1 at the limited performance losing of 0.66dB in PSNR.

본 연구는 삼지구엽초의 기능성 식품학적 이용성 증진을 위한 기초적인 연구로써 우리나라 산야에서 존재하며 예로부터 약용으로 이용되고 있는 삼지구엽초의 주요성분인 icariin을 분리하여 생리활성을 검토하였다. 에탄올로 추출한 삼지구엽초를 극성이 다른 용매인 에틸아세테이트, 부탄올, 헥산, 물, 클로로포름 층으로 분리하여, icariin의 함량을 측정한 결과 각각 27.9, 2.5, 1.7, 1.4, 1.3 μg/g이었고, icariin 수율이 가장 많은 에틸아세테이트 분획물로부터 정제한 icariin 수율은 295.5 μg/g이었으며 대부분 에틸아세테이트에서 용출되는 것을 확인하였다. 용매별 분획물의 항산화 효과는 에틸아세테이트 분획층에서 49.0 μg/mL로 가장 높았으며, 부탄올(59.2 μg/mL), 헥산(119.8 μg/mL), 물(122.0 μg/mL), 클로로포름(138.5 μg/mL) 층의 순으로 나타났으며, 정제된 icariin(15.3 μg/mL)은 대조구인 ascorbic acid(19.5 μg/mL), α-tocopherol(18.2 μg/mL)보다 다소 높은 활성을 나타내었다. Salmonella Typhimurium을 이용한 돌연변이 및 항돌연변이성에 미치는 영향을 조사한 결과, 삼지구엽초에서 분리한 icariin은 TA98과 TA100세포 모두에서 돌연변이성을 나타내지 않았다. 인간면역세포인 B세포와 T세포에서의 면역활성시험을 측정한 결과, icariin은 대조구보다 B세포에서 1.27배, T세포에서 1.28배의 비교적 높은 면역증강활성을 나타내었다. 이러한 결과는 삼지구엽초를 이용한 기능성식품 및 식품재료로서의 이용성 증진을 위한 기초자료로 제공될 수 있을 것으로 판단된다. Epimedium koreanum Nakai is a wild medicinal plant commonly consumed in South Korea due to its health beneficial effects. In the present study, the antioxidative, antimutagenic and immunological activities of E. koreanum Nakai extracts were investigated for their use in food. The yields of icariin compounds from the ethanol extract as well as the ethyl acetate, butanol, hexane, water, and chloroform fractions of E. koreanum were 27.9, 2.5, 1.7, 1.4, and 1.3 μg/g, respectively. The icariin components (295.5 μg/g) were collected from the ethyl acetate fraction by thin layer chromatography (TLC) and analyzed via high performance liquid chromatography (HPLC). The antioxidant activities of each fraction were as follows: ethyl acetate (49.0 μg/mL), butanol (59.2 μg/mL), hexane (119.8 μg/mL), water (122.0 μg/mL), and chloroform (138.5 μg/mL), based on RC₅₀ μg/mL. Icariin, isolated and identified as the main component, showed strong antioxidant activity with a RC₅₀ value of 15.3 μg/mL, which was higher than those of ascorbic acid (19.5 μg/mL) and α-tocopherol (18.2 μg/mL). In an Ames test, none of the fractions produced mutagenic effects on Salmonella Typhimurium TA98 and TA100. In an immunomodulating activity test, the effects of E. koreanum Nakai on B cells (Rhamos) and T cells (Jurkat) were investigated. These results show that the growth and viability of B and T cells were increased by isolated icariin components for 1.27 and 1.28 fold, respectively. These results also provide preliminary data for the development of E. koreanum Nakai as an edible food material.

Epimedium koreanum Nakai is a wild medicinal plant commonly consumed in South Korea due to its beneficial health effects. In this study, the antimutagenic and immunological activities of E. koreanum Nakai extracts were investigated for their use in food. In the immunomodulating activity, the effects of E. koreanum Nakai on the B cell (Rhamos) and T cell (Molt-4) were investigated. The results showed that the growth and viability of the B and T cells were increased and activated more in the ethylacetate (1.35 and 1.48 times) and water fraction (1.30 and 1.40 times), respectively. In the Ames test, none of the fractions produced a mutagenic effect on Salmonella. typhimurium TA98 and TA 100. The ethylacetate fraction showed a strong antimutagenic effect (98%) on and a high butanol fraction (84%) of B(α)P in S. typhimurium TA98 and TA100, respectively. In 4-nitroquinoline-1-oxide (4NQO), all the solvent fractions showed an over 70% antimutagenic effect, except for the chloroform extract. Especially, ethylacetate and butanol showed strong inhibition of the mutagenic effects (80 and 90%) on 4NQO in S. typhimurium TA98 and TA100, respectively. These results provide preliminary data for the development of E. koreanum Nakai as an edible food material.

심방근세포 탈분극 시 전단 자극에 의한 Ca2+ 시그널링 증폭능의 변화

왕준, 우선희 충남대학교 약학대학 의약품개발연구소 2021 藥學論文集 Vol.36 No.-

Contraction of cardiac myocytes is induced by Ca2+-induced Ca2+ release process. In the peripheral junctions of plasma membrane and sarcoplasmic reticulum (SR) membrane of atrial myocytes lacking transverse tubules, small Ca2+ influx via voltage-dependent gating of L-type Ca2+ channels trig- gers much larger amount of Ca2+ release from the SR. In this study we investigated whether shear stress affects such Ca2+ signaling gain function in adult rat atrial myocytes. Intracellular Ca2+ signals and L-type Ca2+ current (ICa) were simultaneously measured in single cells using ultra rapid confocal Ca2+ imaging and whole-cell patch clamp technique, respectively. We found that ICa was significantly reduced by shear stress (∽11 dyn/cm2) at both -30 mV and 0 mV. The ICa-induced Ca2+ releases were generally higher in the periphery than the center. ICa-induced Ca2+ releases in the periphery and center were not altered by shear stress at 0 mV. However, they were increased at -30 mV. The Ca2+ signaling gain representing the efficacy of Ca2+ release at a given ICa was significantly increased by shear stress at -30 mV and 0 mV with much higher augmentation at -30 mV. Our data suggest that shear stress may en- hance a cross-talk between the Ca2+ channels and ryanodine receptors in atrial myocytes on membrane depolarizations.

전단자극 시 나트륨-칼슐 교환체 활성에 의한 횡방향 심방 근세포 Ca2+ 웨이브의 발생

In the present study, we investigated possible mechanism for the triggered global CaH wave from local Ca2+ wave in atrial myocytes under shear stress. Shear stress was applied onto single cells isolated from rat atria and two-dimensional confocal Ca2+ imaging was performed to measure Ca2+ signal. Shear stress of 16 dyn/cm2 induced local Ca2+ wave, which was followed by a rapid transverse global Ca2+ wave inhibition of Na + -ci+ exchange using KB-R7943 suppressed the occurrence of rapid transverse wave ob served under shear stress, but not the shear-induced local wave. in the presence of this chemical local wave was developed to global wave under shear stress which results in slower time to peak of peripheral and central CaH transients. As the preceding local Ca"+ wave signal was higher, the latency of the occurrence of transverse global wave was shorter, suggesting Ca2+ dependence of transverse Ca2+ wave. The results sug-gest that shear stress may activate Na+ -Ca2+ exchange via local CaZ+ wave, triggering the rapid global Ca2+ wave
