한반도 고전문학의 대표작 <춘향전>은 세계 속에 널리 알려진 지명도가 높은 작품의 하나이다. <춘향전>은 작품 그 자체의 독특한 특성과 1950년대 중국과 북한 간의 독특한 사회 역사적 환경으로 인하여 소설, 희곡 등 장르로 번역 개편 되여 광범위하게 수용 전파되면서 독특한 양상을 보여주었다. 1950년대 중국에서의 창극 <춘향전>과 소설 <춘향전>의 번역 전파는 당시 중국과 북한의 국민들간의 친선적 문화 공감대를 형성하는데 일조하였을 뿐만 아니라 중한 문학교류사의 중요한 한 페이지를 장식하였다.
Structure and Stacking Faults in Sr₂Be₂B₂O7 Crystal
X. Y. Meng,X. H. Wen,G. L. Liu 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.52 No.4
Inspired by the successful study on the structure instability of Na₂Al₂B₂O7 (NABO), we extend our interest to a theoretical study, by using density functional theory, on the crystal structures of Sr₂Be₂B₂O7 (SBBO), which possess pretty much the same [M₂B₂O7]∞ (M = Be, Al) double layers as those of the NABO crystal. The energy differences of the SBBO structural variants are found to be so slight that stacking faults could readily occur in the crystal. We propose that different phases may coexist in the same SBBO crystallite, forming domain structure similar to those of NABO which were found by using single-crystal X-ray diffraction. The structural stability of SBBO is closely related to the cohesion forces between [Be₂B₂O7 ∞ layers. A similar structure analysis can be extended to the SBBO isomorphism.

Osmotic stress‐induced phosphorylation by NLK at Ser128 activates YAP
Hong, Audrey W,Meng, Zhipeng,Yuan, Haix2010,Xin,Plouffe, Steven W,Moon, Sungho,Kim, Wantae,Jho, Eekx2010,hoon,Guan, Kunx2010,Liang EMBO 2017 EMBO reports Vol.18 No.1
<P>YAP is the major downstream effector of the Hippo pathway, which controls cell growth, tissue homeostasis, and organ size. Aberrant YAP activation, resulting from dysregulation of the Hippo pathway, is frequently observed in human cancers. YAP is a transcription co-activator, and the key mechanism of YAP regulation is its nuclear and cytoplasmic translocation. The Hippo pathway component, LATS, inhibits YAP by phosphorylating YAP at Ser127, leading to 14-3-3 binding and cytoplasmic retention of YAP. Here, we report that osmotic stress stimulates transient YAP nuclear localization and increases YAP activity even when YAP Ser127 is phosphorylated. Osmotic stress acts via the NLK kinase to induce YAP Ser128 phosphorylation. Phosphorylation of YAP at Ser128 interferes with its ability to bind to 14-3-3, resulting in YAP nuclear accumulation and induction of downstream target gene expression. This osmotic stress-induced YAP activation enhances cellular stress adaptation. Our findings reveal a critical role for NLK-mediated Ser128 phosphorylation in YAP regulation and a crosstalk between osmotic stress and the Hippo pathway.</P>

Liu, G X,Liu, A,Meng, Y,Shan, F K,Shin, B C,Lee, W J,Cho, C R American Scientific Publishers 2015 Journal of Nanoscience and Nanotechnology Vol.15 No.3
<P>Ultra-thin ZrOx thin films on Si substrates were prepared by sol-gel technique and processed with different methods (baked on hot plate at 150 °C, annealed at 500 °C in furnace, and photo-annealed under UV light). The decomposition of the organic groups and the formation of Zr-O bonding in the ZrOx thin films were confirmed by Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. It is found that the ZrOx thin film annealed under UV light shows decent characteristics, including an ultra-small surface roughness, a low leakage current density of 10(-9) A/cm2 at 1 MV/cm, a large breakdown electric field of 9.5 MV/cm, and a large areal capacitance of 775 nF/cm2.</P>

<P><B>Abstract</B></P><P>In the present study, we used TaqMan real‐time polymerase chain reaction to quantify and compare infection of white spot syndrome virus (WSSV) with shrimp production of <I>Fenneropenaeus chinensis</I> cultured in outdoor ponds along the west coast of the South Korea. In 2007, a total of 60 specimens in summer and 116 specimens in autumn were collected from 12 growing‐out ponds and 12 harvest ponds respectively. Pond harvest data were obtained from farmers. Of the summer samples, all specimens were WSSV positive, with a wide range of 12.4–7.0 × 10<SUP>7</SUP> (mean 7.5 × 10<SUP>6</SUP>) copies ng<SUP>−1</SUP> DNA; shrimp production was 1.7 metric tonnes per hectare (mt ha<SUP>−1</SUP>). Of the 116 autumn‐sample specimens, 81 (69.8%) were WSSV positive; WSSV infection had been decreased dramatically, to 0–7.2 (mean 3.5) copies ng<SUP>−1</SUP> DNA. Shrimp production of autumn ponds was 2.1 mt ha<SUP>−1</SUP>. Statistical analysis indicated that the difference in WSSV infections detected in summer and autumn was highly significant (<I>P</I><0.01). In summer, seven ponds (58.3%) with low‐WSSV infection loads (0–1000 WSSV copies ng<SUP>−1</SUP> DNA) had shrimp production of 2.7 mt ha<SUP>−1</SUP>; the others had shrimp production of only 0.2 mt ha<SUP>−1</SUP>. The mean shrimp production between the two infection levels showed a highly statistically significant difference (<I>P</I><0.01).</P>

<P>We present the first survey of dense gas toward Planck Galactic Cold Clumps (PGCCs). Observations in the J = 1-0 transitions of HCO+ and HCN toward 621 molecular cores associated with PGCCs were performed using the Purple Mountain Observatory's 13.7 m telescope. Among them, 250 sources were detected, including 230 cores detected in HCO+. and 158 in HCN. Spectra of the J = 1-0 transitions from (CO)-C-12, (CO)-C-13, and (CO)-O-18 at the centers of the 250 cores were extracted from previous mapping observations to construct a multi-line data set. The significantly low detection rate of asymmetric double-peaked profiles, together with the good consistency among central velocities of CO, HCO+, and HCN spectra, suggests that the CO-selected Planck cores are more quiescent than classical star-forming regions. The small difference between line widths of (CO)-O-18. and HCN indicates that the inner regions of CO-selected Planck cores are no more turbulent than the exterior. The velocity-integrated intensities and abundances of HCO+ are positively correlated with those of HCN, suggesting that these two species are well coupled and chemically connected. The detected abundances of both HCO+ and HCN are significantly lower than values in other low- to high-mass star-forming regions. The low abundances may be due to beam dilution. On the basis of an inspection of the parameters given in the PGCC catalog, we suggest that there may be about 1000 PGCC objects that have a sufficient reservoir of dense gas to form stars.</P>

Based on morphological and physiological characteristics and analysis of the 16S rDNA sequence, strain MJM5763 was identified as a novel strain of <I>Streptomyces</I> and was designated as <I>Streptomyces</I> sp. MJM5763. Treatment with MJM5763 and the crude culture filtrate extract (CCFE) was effective in suppressing anthracnose in detached yam leaves <I>in vitro</I> and reduced incidence and severity of anthracnose in yam plants under greenhouse conditions. The CCFE treatment was the most effective of all the treatments and reduced the anthracnose severity by 85–88% and the incidence by 79–81%, 90 days after inoculation with the pathogen. CCFE treatment was also effective under field conditions and showed a reduction of 86 and 75% of anthracnose severity and incidence, respectively.</P><P><B>Conclusion: </B> <I>Streptomyces</I> sp. strain MJM5763 was effective in biocontrolling anthracnose in yam caused by <I>C.?gloeosporioides</I>.</P><P><B>Significance and Impact of the Study: </B> <I>Streptomyces</I> sp.

<P><B>Summary</B></P><P>Interspecific hybridization is a significant evolutionary force as well as a powerful method for crop breeding. Partial substitution of the AA subgenome in <I>Brassica napus</I> (A<SUP>n</SUP>A<SUP>n</SUP>C<SUP>n</SUP>C<SUP>n</SUP>) with the <I>Brassica rapa</I> (A<SUP>r</SUP>A<SUP>r</SUP>) genome by two rounds of interspecific hybridization resulted in a new introgressed type of <I>B.?napus</I> (A<SUP>r</SUP>A<SUP>r</SUP>C<SUP>n</SUP>C<SUP>n</SUP>). In this study, we construct a population of recombinant inbred lines of the new introgressed type of <I>B.?napus</I>. Microsatellite, intron‐based and retrotransposon markers were used to characterize this experimental population with genetic mapping, genetic map comparison and specific marker cloning analysis. Yield‐related traits were also recorded for identification of quantitative trait loci (QTLs). A remarkable range of novel genomic alterations was observed in the population, including simple sequence repeat (SSR) mutations, chromosomal rearrangements and retrotransposon activations. Most of these changes occurred immediately after interspecific hybridization, in the early stages of genome stabilization and derivation of experimental lines. These novel genomic alterations affected yield‐related traits in the introgressed <I>B.?napus</I> to an even greater extent than the alleles alone that were introgressed from the A<SUP>r</SUP> subgenome of <I>B.?rapa</I>, suggesting that genomic changes induced by interspecific hybridization are highly significant in both genome evolution and crop improvement.</P>
