韓國女眞語文學的豊碩成果 : 金東昭敎授《女眞語滿語硏究》讀後
김계종 효성여자대학교 한국전통문화연구소 1995 韓國傳統文化硏究 Vol.10 No.-
我從遼寧回到京的第二年, 使我高興論一件事, 是韓國女眞語文學家星女子大學金東昭敎授的光臨舍下, 記得當時是承延邊大學崔羲秀敎授同來介紹的. 初談之際, 卽感到金東昭敎授對女眞文硏究的深度·廣度, 令人佩服. 兩年之後, 使我更高興的事美得到了金東昭敎授的文集≪女眞語滿語硏究≫, 這本書是中央民族大學黃有福敎授譯成的中文本. 本來我曾與金東昭敎授互贈著作. 但承他寄贈的≪韓國語與通古斯語音韻比較硏究≫(1981), ≪同文類解滿州文語語彙≫(1982), 皆 金東昭敎授授執敎的曉星女子大學出版部所出, 印製精良. 彌足診貴. 而奉面又以≪女眞譯語≫等書影爲地, 更覺親切, 其眞對女眞語文硏究之重視, 亦由此可見. 我本早想寫-篇介紹, 但因限于朝鮮語文程度, 遲遲不果. 今得此中譯本能洞悉著作眞諦, 理當爲之游揚.

Bioequivalence of two cilostazol tablets, the Pletaal^(R)(Korea Otsuka Pharmaceutical Co., Ltd.) and the Cilozol^(R)(Hanmi Pharmaceutical Co., Ltd.), was evaluated according to the guideline of KFDA, Sixteen normal male volunteers(age 20~29 years old) were divided into two groups and a randomized 22 cross-over study was employed. After two tablets containing 50㎎ of cilostazol were orally administered. blood was taken at predetermined time intervals and the concentration of cilostazol in plasma was determined with an HPLC method using UV detector. The pharmacokinetic parameters(C_(max), T_(max) and AUC_(t)) were calculated and ANOVA was utilized for the statistical analysis of parameters. The results showed that the differences in C_(max), T_(max) and AUC_(t) between two tablets were 4.99%, 1.74% and 7.68%, respectively. The powers(1-β) for C_(max), T_(max) and AUC_(t) were83.92%, 80.12% and 85.03%, respectively. Detectable differences(Δ) and confidence intervals were all less than 20%, and confidence interval of all the parameters were also less than 20% at the significance level(α) of 0.05. All of these parameters met the criteria of KFDA for bioequivalence, indicating that Cilozol^(R) tablet is bioequivalent to Pletaal^(R) tablet.

<P>Bernal-stacked bilayer graphene is uniquely suited for application in electronic and photonic devices because of its tunable band structure. Even though chemical vapor deposition (CVD) is considered to be the method of choice to grow bilayer graphene, the direct synthesis of high-quality, large-area Bernal-stacked bilayer graphene on Cu foils is complicated by overcoming the self-limiting nature of graphene growth on Cu. Here, we report a facile H<SUB>2</SUB>O-assisted CVD process to grow bilayer graphene on Cu foils, where graphene growth is controlled by injecting intermittent pulses of H<SUB>2</SUB>O vapor using a pulse valve. By optimizing CVD process parameters fully covered large area graphene with bilayer coverage of 77 ± 3.6% and high AB stacking ratio of 93 ± 3% can be directly obtained on Cu foils, which presents a hole concentration and mobility of 4.5 × 10<SUP>12</SUP> cm<SUP>-2</SUP> and 1100 cm<SUP>2</SUP> V<SUP>-1</SUP> s<SUP>-1</SUP>, respectively, at room temperature. The H<SUB>2</SUB>O selectively etches graphene edges without damaging graphene facets, which slows down the growth of the top layer and improves the nucleation and growth of a second graphene layer. Results from our work are important both for the industrial applications of bilayer graphene and to elucidate the growth mechanism of CVD-graphene.</P> [FIG OMISSION]</BR>
Tradeoff Control of Multi-exposure Lithography for SU-8 Photochemical Reaction Channel Formation
Qi-Ming Chen,Jin-Yun Zhou,Yi-Ming Hu,Qi Zheng 한국바이오칩학회 2020 BioChip Journal Vol.14 No.4
A method involving multi-exposure with low-power is presented to fabricate an SU-8 mold based on a digital micromirror device (DMD) maskless lithography with an LED source at a wavelength of 405 nm. The SU-8 mold is used for the fabrication of a PDMS concentration gradient generator (CGG). During a one-time exposure, it is easy to over-expose at the top and under-expose at the bottom of a thick SU-8, which then forms a T-shaped structure. This is more obvious for high-absorption coefficients such as 365 nm. We found that by taking advantage of the partially absorbed and partially transmissive characteristics of the 405-nm wavelength, multi-exposure can form an effective photochemical reaction channel in SU-8 and can solve the problem mentioned above. However, excessive exposure will cause the linewidth to increase, therefore, it is necessary to find a tradeoff for the number of multi-exposure times. For a 55-μm thick SU-8, the tradeoff threshold is found to be 25. Three types of SU-8 CGG molds were fabricated at this threshold. The results indicate that the actual profile of the SU-8 mold shows good agreement with the design profile without any T-shaped structures.

Incorporation of an eicosapentaenoic acid/docosahexaenoic acid (EPA/DHA) moiety into diacylglycerol(DAG) oil using lipase-catalyzed esterification was optimizedusing an ethyl ester form of EPA/DHA. A response surfacemethodology (RSM) was used to optimize reactionparameters (time, temperature, and substrate mole ratio) forincorporation of DHA and EPA into DAG oil. Predictivemodels for DHA+EPA contents of DAG and the amountof DAG produced after esterification were adequate andreproducible. DHA+EPA contents of DAG significantlyincreased with reaction time and substrate mole ratio(p<0.05). In contrast, the reaction temperature negativelyaffected the amount of DAG after esterification. Synthesisof DHA+EPA-enriched DAG was optimized for a maximumDAG content with the highest DHA+EPA content, inwhich 630.0 mg of DAG containing 34.8% DHA and EPAwas predicted using the RSM model. The optimal reactionconditions were predicted at 20.6 h, 57.9 and a DHA/EPAenrichedethyl ester: DAG oil ratio of 2.5:1.
