Objectives : US extract is a mixture of each extract of Ulmi cortex and Smilacis rhizoma. In this study, we investigated the antioxidant, anti-inflammatory, antibacterial, and ovoprotective effects of US extract in in vitro model to identify potential candidates for improving female reproductive function. Methods : The antioxidant activity of US extract was measured using 1,1-diphenyl- 2-picrylhydrazyl free radical and superoxide anion radical scavenging assays. The anti-inflammatory effect of US extract on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells were determined with a nitric oxide (NO) assay, enzyme linked immunosorbent assays, and western blots analysis. The antibacterial activity of US extract against vaginitis infection microorganisms were determined with disc diffusion and minimum inhibitory concentration assays. The ovoprotective effect of US extract on 4-vinylcyclohexene diepoxide (VCD)-induced ovotoxicity in CHO-K1 cells were evaluated with a cell viability assay. Result : US extract showed good antioxidant capacity and inhibited LPS-induced NO production as well as iNOS and COX-2 expression and secretion of pro-inflammatory cytokine IL-6 without affecting the cell viability. It showed significant clear zones for Staphylococcus aureus and Candida albicans but did not indicate the clear zones for Escherichia coli and Enterococcus faecium. VCD-induced ovotoxicity in CHO-K1 cells was significantly reduced by US extract pre-treatment. Conclusions : These results demonstrate that US extract has antioxidant activity, anti-inflammatory effects on the LPS-stimulated macrophages, antibacterial activity against vaginitis infection microorganisms, and protective effects on the ovarian cells against VCD-induced ovotoxicity. These findings suggest that the US extract can be used as new prescriptions, supplements, functional foods, and cosmetics for improving female reproductive function.

Direct monitoring of recombination zone shift during lifetime measurement of phosphorescent organic light-emitting diodes

전상규,이준엽 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.32 No.-

Recombination zone of phosphorescent organic light-emitting diodes during lifetime measurement wasdirectly monitored using a red sensing layer inserted at different positions of blue phosphorescentemitting layer. The shift of recombination zone could be identified by the change of red intensity of thered sensing layer because the red intensity reflects the exciton density around the red sensing layer. Gradual shift of the recombination zone from hole transport layer side to electron transport layer sidecould be directly tracked according to driving time of the device.

Thermometer Decoder를 SSCG에 적용한 저잡음 특성의 DC-DC Converter 설계

전상규,윤태영,조종완,이강윤 대한전자공학회 2019 전자공학회논문지 Vol.56 No.12

This paper describes various types of pulse width modulation (PWM) control method applied to DC-DC converter. The proposed Buck converter reduces harmonics and output ripple voltage using Sawtooth Generator and Spread Spectrum Clock Generator (SSCG). A low ripple voltage was obtained using a random generator and a thermometer decoder, and up to 90.16% efficiency was achieved using a capacitor bank bolck instead of a bias current block. The switching frequency is 3MHz, spreading from 2MHz to 3MHz using the Spread Spectrum Clock Generator. 본 논문에서는 DC-DC converter에 적용되는 다양한 유형의 Pulse Width Modulation(PWM) 방식의 제어 방법에 대하여 설명한다. 여기서 제안된 Buck converter는 Sawtooth Generator와 Spread Spectrum Clock Generator(SSCG) 를 사용하여 고조파, 출력 리플 전압 등을 감소시킨다. Random generator와 Thermometer decoder를 사용하여 낮은 리플 전압을 얻었고 Bias current block대신 Capacitor bank bolck을 사용하여 최대 90.16%의 효율을 달성했다. 스위칭 주파수는 3MHz로 Spread Spectrum Clock Generator를 사용하면 2MHz-3MHz에서 확산된다.

전상규,김옥현,박수미,이주희,박선동 대한한의학방제학회 2020 大韓韓醫學方劑學會誌 Vol.28 No.1

Objectives : Glucoraphanin is one of the well-known natural glucosinolates found in cruciferous plants. In the present study, we investigated the effects and molecular mechanism of glucoraphanin in dexamethasone-induced skeletal muscle atrophy in vitro model. Methods : The cytotoxic effects of glucoraphanin on C2C12 myoblasts or myotubes were evaluated by MTT assay. The glucoraphanin was evaluated effects in dexamethasone-induced skeletal muscle atrophy in C2C12 myotubes using a real-time PCR, western blots analysis, and immunofluorescence staining of myosin heavy chain. Result : Glucoraphanin had no cytotoxicity on both C2C12 myoblasts or myotubes. Dexamethasone markedly induced muscle atrophy by up-regulating muscle-specific ubiquitin E3 ligase markers, atrogin-1 and MuRF1, and down-regulating MyoD, a myogenic regulatory factor whereas co-treatment of glucoraphanin and dexamethasone dose-dependently inhibited it. Furthermore, decreased expressions of p-Akt, p-FOXO1, and p-FOXO3a induced by dexamethasone were reversed by co-treatment with glucoraphanin and dexamethasone. In addition, dexamethasone obviously reduced myotube diameters, while co-treatment of glucoraphanin and dexamethasone increased those to a similar level as control. Conclusions : These results show that glucoraphanin suppresses dexamethasone-induced muscle atrophy in C2C12 myotubes through activation of Akt/FOXO signaling pathway.

전상규,Jeon, Sang-K. 한국전기화학회 2007 한국전기화학회지 Vol.10 No.2

백금족/수용액 계면에서 Langmuir, Frumkin, Temkin 흡착등온식(${\theta}\;vs.\;E$)을 결정하기 위해 최적중간주파수 일 때 위상이동($0^{\circ}{\leq}-{\varphi}{\leq}90^{\circ}$) 거동($-{\varphi}\;vs.\;E$)과 표면피복율($1{\geq}{\theta}{\geq}0$) 거동(${\theta}\;vs.\;E$) 사이의 선형 관계식 연구에 관한 위상이동 방법 및 상관계수를 제안하고 증명하였다. Ir/0.1 M KOH수용액 계면에서 음극 $H_2$ 발생 반응에 관한 수소의 Langmuir 및 Temkin 흡착등온식(${\theta}\;vs.\;E$), 평형상수(Langmuir 흡착등온식: $K=3.3{\times}10^{-4}mol^{-1}$, Temkin 흡착등온식: $K=3.3{\times}10^{-3}{\exp}(-4.6{\theta})\;mol^{-1}$), 상호작용 파라미터(Temkin 흡착등온식: g=4.6), 표준자유에너지($K=3.3{\times}10^{-4}mol^{-1}$ 일 때 ${\Delta}G_{ads}^0=19.9kJ\;mol^{-1},\;K=3.3{\times}10^{-3}{\exp}(-4.6{\theta})\;mol^{-1}$ 및 $0.2<{\theta}<0.8$일 때 $16.5<{\Delta}G_{\theta}^0<23.3kJ\;mol^{-1}$)를 결정한다. 수소 흡착부위의 비균일 및 측 방향 상호작용 효과는 무시할 수 있다. ${\theta}$의 중간값 즉, $0.2<{\theta}<0.8$일 때 Langmuir 또는 Frumkin 흡착등온식과 상관관계에 있는 Temkin 흡착등온식은 상관계수를 이용하여 쉽게 결정할 수 있다. 위상이동 방법 및 상관계수는 흡착동온식(${\theta}\;vs.\;E$) 및 연관된 전극속도론과 열역학 파라미터(K, g, ${\Delta}G_{ads}^0, {\Delta}G_{\theta}^0$)를 결정하기 위한 정확하고 확실한 기술 및 방법이다. The phase-shift method and correlation constants for studying a linear relationship between the behavior ($-{\varphi}\;vs.\;E$) of the phase shift ($0^{\circ}{\leq}-{\varphi}{\leq}90^{\circ}$) for the optimum intermediate frequency and that (${\theta}\;vs.\;E$) of the fractional surface coverage ($1{\geq}\theta{\geq}0$) have been proposed and verified to determine the Langmuir, Frumkin, and Temkin adsorption isotherms (${\theta}\;vs.\;E$) at noble metal/aqueous electrolyte interfaces. At an Ir/0.1 M KOH aqueous electrolyte interface, the Langmuir and Temkin adsorption isotherms (${\theta}\;vs.\;E$), equilibrium constants ($K=3.3{\times}10^{-4}\;mol^{-1}$ for the Langmuir and $K=3.3{\times}10^{-3}{\exp}(-4.6{\theta})\;mol^{-1}$ for the Temkin adsorption isotherm), interaction parameter (g = 4.6 for the Temkin adsorption isotherm), and standard free energies (${\Delta}G_{ads}^0=19.9kJ\;mol^{-1}\;for\;K=3.3{\times}10^{-4}\;mol^{-1}$ and $16.5<{\Delta}G_{\theta}^0<23.3\;kJ\;mol^{-1}\;for\;K=3.3{\times}10^{-3}{\exp}(-4.6{\theta})\;mol^{-1}\;and\;0.2<\theta<0.8$) of H for the cathodic $H_2$ evolution reaction are determined using the phase-shift method and correlation constants. The inhomogeneous and lateral interaction effects on the adsorption of H are negligible. At the intermediate values of ${\theta},\;i.e,\;0.2<{\theta}<0.8$, the Temkin adsorption isotherm (${\theta}\;vs.\;E$) correlating with the Langmuir or the Frumkin adsorption isotherm (${\theta}\;vs.\;E$), and vice versa, is readily determined using the correlation constants. The phase-shift method and correlation constants are accurate and reliable techniques to determine the adsorption isotherms (${\theta}\;vs.\;E$) and related electrode kinetic and thermodynamic parameters(K, g, ${\Delta}G_{ads}^0, {\Delta}G_{\theta}^0$).
