<P>The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain DCY69(T) is JX233806. A Gram-reaction-negative, oxidase- and catalase-positive, non-gliding motile strain, designated strain DCY69(T), was isolated from the soil of a ginseng field in the Republic of Korea. Colonies of strain DCY69(T) were circular, 0.5-1.5 mm diameter, yellow, and convex on an R2A agar plate after 2 days. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain DCY69(T) belonged to the genus Flavobacterium with 90.5-98.3% gene sequence similarity. The major predominant quinone was MK-6. The major cellular fatty acids were iso-C15:0, iso-C17:0 3-OH, iso-C15:0 3-OH and summed feature 3 (containing C16:1ω7c and/or C16:1ω6c). The major polar lipids were phosphatidylethanolamine, one unidentified aminolipid and unidentified polar lipids (L1, L2). The genomic DNA G+C content of strain DCY69(T) was 35.0mol%. The strain DCY69(T) transformed ginsenoside Rb1 into Rd and F2. Based on the polyphasic taxonomic data, strain DCY69(T) is considered to represent a novel species of the genus Flavobacterium, for which the name Flavobacterium panaciterrae sp. nov. is proposed. The type strain is DCY69(T)(= KCTC 32392(T) = JCM 19161(T)), isolated from the soil of a ginseng field in the Republic of Korea.</P>

Based on the essentials of the Korean Academic Society for Public Relations (KASPR) 2022 Distinguished Lecture given by Dr. Glen T. Cameron and Dr. Yan Jin, this conceptual piece provides an overview of the contingency theory of strategic conflict management, its application to research, and future directions, with a focus on the theory-practice interconnections of the contingency theory in public relations across multiple contexts. How the contingency theory has been and can be further applied to advancing crisis communication and conflict management research and practice in Asia is further discussed.

BACKGROUND: Groundwater is believed to possess many beneficial effects due to its natural source of various minerals. In this study, we examined the effects of natural Jeju groundwater S1 (SamdasooTM), S2 and S3 pumped up from different locations of Jeju Island, Korea, along with local tap water, on body weight gain, serum lipids and lipoproteins, and liver histopathology in high-fat diet-induced hyperlipidemic rats. MATERIALS/METHODS: Rats were randomly and equally divided into 6 groups. Different water samples were supplied to the hyperlipidemic rats as their daily drinking water and the widely-used anti-hyperlipidemic drug simvastatin was used as a positive control. Body weight, serum lipids and lipoproteins were measured weekly. Liver weight, liver index and liver histopathology were examined after the execution of the rats. RESULTS: After drinking Jeju groundwaters for two months, S2 but not S3 significantly reduced weight growth and serum triglycerides levels and increased high density lipoprotein-C (HDL-C) without affecting total cholesterol or LDL-C. S1 and particularly S2 significantly reduced the severity of liver hypertrophy and steatosis. All Groundwaters had much higher contents of vanadium (S3>S2>S1>>tap water) whereas S1 and S2 but not S3 markedly blocked autoxidation of ferrous ions. CONCLUSION: Jeju Groundwater S1 and particularly S2 exhibit protective effects against hyperlipidemia and fatty liver and hypothesize that the beneficial effect of Jeju Groundwaters may be contributed from blockade of autoxidation of ferrous ions rather than their high contents of vanadium.
Study on Female Consciousness of Jin Renshun`s Short Stories
김염 ( Jin Yan ) 한국중국어문학회 2014 中國文學 Vol.81 No.-
김인순은 “70년대에 출생한 작가” 중 “절제미”의 서사에 능한 대표적인 여류작가이다. 70년대 생의 다른 여류작가들과는 달리, 그녀의 소설은 여성의 신체를 통한 욕망의 관능적 표출을 절제하였다. 그녀의 소설은 현대사회에서 남성중심주의와 직접적인 충돌, 저항 대신 `가면`을 쓰고 자신의 욕망을 간접적으로 표출하는 여성상을 그리는 데 집중하였고, 전통적인 가부장제 사회의 폐단을 가장 잘 보여주는 조선시대를 배경으로 하는 고전적인 텍스트에 대한 재구성을 통하여 가부장제의 억압에 반항하는 도발적인 여성상을 표출하였다. 남성들은 거의 다 무기력한 형상으로 등장하며 집단적인 “거세” 양상을 보이고 있다. Jin Renshun is a representative female writer skilled in restrained narration from the group of “writers born in 1970s”. Unlike other female writers in the same group, she refrains herself from exposing women`s figures to express the desire. Her works tend to shape the images of women who masquerade themselves while satisfying their desires to avoid direct conflicts with male-controled system in modern society, or, build images of women who directly resist tyranny of patriarchy system by reconstructing classical texts of the Joseon Dynasty period which reflect the malady of traditional patriarchy society. Almost all the male characters show powerlessness and “castration” in her works.
ROS1 gene rearrangement and copy number gain in non-small cell lung cancer.
Jin, Yan,Sun, Ping-Li,Kim, Hyojin,Park, Eunhyang,Shim, Hyo Sup,Jheon, Sanghoon,Kim, Kwhanmien,Lee, Choon-Taek,Chung, Jin-Haeng Springer International 2015 Virchows Archiv Vol.466 No.1
<P>ROS1 has attracted much attention as a possible oncogenic driver and ROS1-rearranged tumors show sensitivity to most ALK inhibitors. We aimed to clarify the prevalence of ROS1 gene rearrangement and investigate the clinical implications of ROS1 gene copy number gain (CNG) in non-small cell lung cancer (NSCLC) patients. We carried out fluorescent in situ hybridization with ROS1 and centromere enumeration 6 probes and immunohistochemistry for ROS1 protein expression. ROS1 rearrangement was detected in 3 of 375 samples (0.8 %); all of whom were female, never-smokers, and harbored an adenocarcinoma component. ROS1 gene CNG was found in 18 cases (4.8 %). ROS1 gene CNG was significantly associated with shorter disease-free survival (DFS, 12 vs. 58 months; p = 0.003) and shorter overall survival (OS, 40 vs. 67 months; p <0.001) than the group without CNG. Multivariate analysis confirmed that ROS1 gene CNG was significantly associated with poorer DFS (hazard ratio [HR]=2.16, 95 % confidence interval [CI] = 1.22-3.81, p = 0.008), and OS ([HR] = 2.53, 95 % [CI] = 1.31-4.89, p = 0.006). ROS1 protein overexpression was observed in 5.0 % (18 out of 357), of which 2 cases harbored ROS1 gene rearrangement. There was no statistically significant correlation between ROS1 gene CNG and protein overexpression. This study demonstrated ROS1 gene rearrangement was detected in 0.8 % of surgically resected NSCLC; and ROS1 gene CNG is an independent poor prognostic factor. This survival analyses may contribute to future studies on the utility of ROS1-targeted therapy for patients.</P>

<P>A systematic comparison of the ginsenosides and physicochemical properties of white ginseng (WG), red ginseng (RG) and black ginseng (BG) was performed. The purpose of the present study was to identify the effects of the physicochemical properties by steaming process. During the steaming process, ginsenosides transform into specific ginsenosides by hydrolysis, dehydration and isomerization at C-3, C-6 or C-20. Steaming ginseng led to a significant increase in reducing sugar, acidic polysaccharide and phenolic compounds content. Antioxidative properties were investigated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity, compared with BHA (Butylated hydroxyanisole). RG and BG exhibited higher antioxidant activity than WG. The maximum residue level for Benzo(a)pyrene was established to 5 μg/kg in food products. The levels of benzo(a)pyrene in WG and RG were not detected. Benzo(a)pyrene was detected in the BG, the content was 0.17 μg/kg. The scientific achievements of the present study could help consumers to choose different type of ginseng products available on the market.</P>

The ammonium ion-selective electrodes ($NH^+_4$-ISEs) based on the tetrahydrofuran(THF)-containing-16-crown-4 derivatives,1,4,6,9,11,14,16,19-tetraoxocycloeicosane ($L^1$) and 5,10,15,20,-tetramethyl-1,4,6,9,11,14,16,19-tetraoxocycloeicosane ($L^2$), were prepared and the electrode characteristics were tested. The conditioned $NH_4^+$-ISEs (E1) based on $L^1$ with TEHP as a plasticising solvent mediator gave best results with near-Nernstian slope of 53.9 mV/decade of activity, detection limit of $10^{-4.9}$ M, and enhanced selectivity coefficients for the $NH^+_4$ ion with respect to an interfering $K^+$ ion (log $K^{pot}_{NH_4^+,K^+}$ = -1.84). This result was compared to other ammonium ionophores reported previously, for example, that of nonactin (log $K^{pot}_{NH_4^+,K^+}$ = -0.92). The proposed electrode showed no significant potential changes in the range of 3.0 < pH < 9.0.
