A Comparative Study of Compliment Responses between Chinese and Korean EFL Learners

Zhang, In-Jun 부산외국어대학교 외국어연구소 2021 외국어연구 Vol.34 No.-

This study focused on investigating the similarities and differences between Chinese and Korean L2 learners shows that there’s no universal pattern that can be used to describe the two groups’ CRs. Both the two groups response to compliments in the following preference sequence, Accept, Evade and Reject. As for micro levels, Chinese L2 learners made more use of Accept strategies while Korean L2 learners used Evade more. Due to different second language acquisition methods, Chinese L2 learners showed to have a more direct attitude towards accepting compliments. However, there are still some limitations in this study. First, the sample of participants is a little bit small. Based on Tang and Zhang’s study (2009), there are people who prefer to use Reject. However, in this study, there were no Reject responses among all the Chinese L2 learners’ replies. This, to some degree, may influence the results and comparative analyses of the two groups. Second, before the DCT, the background survey asked the participants whether they had experiences of being in English speaking countries and why they came there. However, this variable is not analyzed in the study. Since there is no standard criterion for personal experience, it’s difficult to know how much personal experience will influence participants’ expressions. Finally, although the DCT is designed as short as possible, it’s undeniable that it still takes participants some time to finish it. Whether the participant expresses all he/she wants to or not is hard to know and this is also a possible variable that has influences on the experimental data. Further research on the CRs of Chinese L2 learners and Korean L2 learners needs a more sophisticated and accurate experiment design and I hope this study, though imperfect, can be of some help to relevant research.

As the storage capacity of a computer system is rapidly increasing and the cost of computer hardware is decreasing continuously, users can easily manage multimedia data on the personal computer. Especially, various image view programs are widely used to manage image files at the present time. However, since most of these programs do not use a database management system(DBMS), it is very difficult for users to use them efficiently. In this paper, we designed and implemented a Digital Album by using an object-relational database management system, called PARODY(Persistent, Almost, Relational Object Database sYstem) that implements a persistent object database with a relatively simple interface to its C++ class library. Since PARODY is used as a data storage manager of the Digital Album, users can manage(i.e., insert, update, and delete) an image database and search for the required image data from the image database easily. In addition, we use OWL(Object Windows Library) of Borland C++ to implement the user interface of the Digital Album efficiently.

Jiang Jiang Qin,Jia Xian Zhu,Wei Dong Zhang1,2,Yan Zhu,Jian Jun Fu,Xiao Hua Liu,Hui Zi Jin 대한약학회 2009 Archives of Pharmacal Research Vol.32 No.10

A new ent-kaurane type diterpenoid glycoside, 17-O-β-D-glucopyranosyl-16α-ent-kauran-19-oic acid (1), together with 17-hydroxy-16α-ent-kauran-19-oic acid (2), 16α,17-dihydroxyl-ent-kauran-19-oic acid (3), and 16α-hydroxy-17-acetoxy-ent- kauran-19-oic acid (4) were isolated from the aerial parts of Inula japonica Thunb. The structure of 1 was determined mainly by use of 1D and 2D NMR spectroscopic techniques including HSQC, 1H-1H COSY, HMBC, and NOESY. In addition, 4 exhibited significant inhibitory activity on NO production in LPS-stimulated RAW264.7 cells with IC50 value of 14.3 μg/mL.

Bottom-contact (BC) copper phthalocyanine (CuPc) thin film transistor with UV/ozone treated Au as a source/drain electrode was fabricated and the contact resistance was estimated from the transmission line method (TLM). Comparing the properties of OTFT with untreated Au electrode, the performance of the BC CuPc-TFT with the UV/ozone treated Au electrodes was significantly improved: saturation mobility increased from 4.69 × 10−3 to 2.37 × 10−2 ㎠/V s, threshold voltage reduced from −29.1 to −6.4 V, and threshold swing varied from 5.08 to 2.25 V/decade. The contact resistance of the device with UV/ozone treated Au electrodes was nearly 20 times smaller than that of the device with untreated Au electrodes at the gate voltage of −20 V. This result indicated that using the UV/ozone treated Au electrode is an effective method to reduce the contact resistance. The present BC configuration with UV/ozone treated Au electrodes could be a significant step towards the commercialization of OTFT technology.

Effect of Bcl-2 on Apoptosis and Transcription Factor NF-κB Activation Induced by Adriamycin in Bladder Carcinoma BIU87 Cells

Zhang, Guo-Jun,Zhang, Zhe Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.4

Resistance to apoptosis is a major obstacle preventing effective therapy for malignancies. Bcl-2 plays a significant role in inhibiting apoptosis. We reconstructed a stable human Bcl-2 transfected cell line, BIU87-Bcl-2, that was derived from the transfection of human bladder carcinoma cell line BIU87 with a plasmid vector containing recombinant Bcl-2 [pcDNA3.1(+)-Bcl-2]. A cell line transfected with the plasmid alone [pcDNA3.1(+)-neo] was also established as a control. BIU87 and BIU87-neo proved sensitive to adriamycin induced apoptosis, while BIU87-Bcl-2 was more resistant. In view of the growing evidence that NF-${\kappa}B$ may play an important role in regulating apoptosis, we determined whether Bcl-2 could modulate the activity of NF-${\kappa}B$ in bladder carcinoma cells. Stimulation of BIU87, BIU87-neo and BIU87-Bcl-2 with ADR resulted in an increase expression of NF-${\kappa}B$ (p<0.001). The expression of NF-${\kappa}B$ in BIU87-Bcl-2 was higher than in the other two cases, with a concomitant reduction in the $I{\kappa}B{\kappa}$ protein level. These results suggest that the overexpression of Bcl-2 renders human bladder carcinoma cells resistant to adriamycin-induced cytotoxicity and there is a link between Bcl-2 and the NF-${\kappa}B$ signaling pathway in the suppression of apoptosis.

Zhang, Hang,Duan, Chao-Jun,Chen, Wei,Wang, Shao-Qiang,Zhang, Sheng-Kang,Dong, Shuo,Cheng, Yuan-Da,Zhang, Chun-Fang Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.5

The SH2B1 adaptor protein is recruited to multiple ligand-activated receptor tyrosine kinases that play important role in the physiologic and pathologic features of many cancers. The purpose of this study was to assess SH2B1 expression and to explore its contribution to the non-small cell lung cancer (NSCLC). Methods: SH2B1 expression in 114 primary NSCLC tissue specimens was analyzed by immunohistochemistry and correlated with clinicopathological parameters and patients' outcome. Additionally, 15 paired NSCLC background tissues, 5 NSCLC cell lines and a normal HBE cell line were evaluated for SH2B1 expression by RT-PCR and immunoblotting, immunofluorescence being applied for the cell lines. Results: SH2B1 was found to be overexpressed in NSCLC tissues and NSCLC cell lines. More importantly, high SH2B1 expression was significantly associated with tumor grade, tumor size, clinical stage, lymph node metastasis, and recurrence respectively. Survival analysis demonstrated that patients with high SH2B1 expression had both poorer disease-free survival and overall survival than other patients. Multivariate Cox regression analysis revealed that SH2B1 overexpression was an independent prognostic factor for patients with NSCLC. Conclusions: Our findings suggest that the SH2B1 protein may contribute to the malignant progression of NSCLC and could offer a novel prognostic indicator for patients with NSCLC.

In response to the environmental problems caused by the difficulty of direct degradation of the raw materials usedin traditional geogrids and the impact of different temperatures on the mechanical properties of geogrids in practicalengineering applications, based on 3D printing technology, polylactic acid (PLA), carbon fiber reinforced polylactic acid(PLA/CF), and thermoplastic polyurethane (TPU) geogrids were fabricated. The 3D printed geogrids and the fiberglassgeogrids used in the actual project were tested in indoor tensile tests under different temperature conditions. The mechanicalproperties of the geogrids of the four kinds of materials and six kinds of temperature were analyzed. The microstructure of thegeogrids after tensile tests was investigated based on scanning electron microscopy technology to further analyze the effectsof different materials and temperatures on the mechanical properties of the geogrids. The results showed that the tensilestrength of PLA/CF geogrids and PLA geogrids decreased with increasing temperature. The tensile strength of fiberglassgeogrids increased with rising temperatures. The tensile strength of PLA/CF geogrids was significantly better than PLAgeogrids. Due to the addition of carbon fiber in PLA, PLA/CF can bear more tensile force at high temperatures. With theincrease of temperature, the elongation at break of PLA/CF geogrids and fiberglass geogrids increased, but the elongation atbreak of PLA geogrids decreased. The elongation at break of PLA/CF geogrids was significantly lower than that of PLAgeogrids. TPU geogrids had high tensile capacity in a high-temperature environment, and they also had high elasticity andmore significant elongation at break, which was not suitable to be used as geogrid material.

Acetylation of Smc3 by Eco1 Is Required for S Phase Sister Chromatid Cohesion in Both Human and Yeast

Zhang, Jinglan,Shi, Xiaomin,Li, Yehua,Kim, Beom-Jun,Jia, Junling,Huang, Zhiwei,Yang, Tao,Fu, Xiaoyong,Jung, Sung Yun,Wang, Yi,Zhang, Pumin,Kim, Seong-Tae,Pan, Xuewen,Qin, Jun Elsevier 2008 Molecular cell Vol.31 No.1

<P><B>Summary</B></P><P>Sister chromatid cohesion is normally established in S phase in a process that depends on the cohesion establishment factor Eco1, a conserved acetyltransferase. However, due to the lack of known in vivo substrates, how Eco1 regulates cohesion is not understood. Here we report that yeast Eco1 and its human ortholog, ESCO1, both acetylate Smc3, a component of the cohesin complex that physically holds the sister chromatid together, at two conserved lysine residues. Mutating these lysine residues to a nonacetylatable form leads to increased loss of sister chromatid cohesion and genome instability in both yeast and human. In addition, we clarified that the acetyltransferase activity of Eco1 is essential for its function. Our study thus identified a molecular target for the acetyltransferase Eco1 and revealed that Smc3 acetylation is a conserved mechanism in regulating sister chromatid cohesion.</P>

Jun Zhang,De-Song Tang,Shu-Ying Gong,Ying-Bin Zhang,Ping Chen,Zhi-Lei Gu 한국차학회 2015 한국차학회지 Vol.- No.S

The relationships among the concentrations of chemical compositions, scores of sensory quality and price were studied based on 112 jasmine tea samples. Linear correlation analysis showed that 5 quality attributes (appearance, liquor color, aroma, taste and infused leaves) were positively correlated with each other and to the sum. 5 quality attributes and total quality score were logarithm relevant to price with the coefficients of determination R2 were 0.855, 0.667, 0.836, 0.900, 0.906 and 0.914. The six taste attributes could be grossly divided into two groups. Tenderness, sweetness, freshness and mellowness were grouped showing positive correlation with taste score, total quality score and price, while heaviness and thickness were grouped for opposite correlation. There were positive correlation within the same group and negative correlation between two different groups. The concentrations of polyphenols, amino acid, water extract, gallocatechin (GC), epigallocatechin (EGC), catechin (C), epicatechin (EC), epigallocatechin gallate (EGCG), gallocatechin gallate (GCG) and epicatechin gallate (ECG) in tea infusions were negatively correlated with tenderness, sweetness, freshness, mellowness, taste score, total quality score and price but positively correlated with heaviness and thickness (except some individual components), while gallic acid (GA) was the opposite. Multiple linear regression equations of taste score and total quality score were established. The back substitution was of high correlation between predicted and actual value and acceptance rate was over 90%.
