This paper analyzes talk show host Yu Jae-seok’s questioning technique in < You Quiz on the Block >. By analyzing question functions in the dialogue, the importance of the questions was identified and the role of the question function in the progress of the dialogue was examined. The analysis revealed that Yu Jae-seok used information-oriented questions and relationship-oriented questions in almost equal proportions. While communicating, it is paramount that the facilitator obtains the information he or she seeks, but relationship-oriented questions conveying respect, care, and interest in the other party are also important, even if specific information is not requested in the dialogue. Thus, Yu Jae-seok elicited interest and empathy from the performers by asking not only “information-oriented questions,” which solely seek to obtain information, but also “empathetic information-seeking questions.”

공손 표현에 대한 중국인 한국어 학습자와 한국어 모어 화자의 인식 차이 비교 연구 -인스턴트 메신저 대화를 중심으로-

( Niu Lei ),권순희 ( Kwon Soonhee ) 이중언어학회 2021 이중언어학 Vol.85 No.-

This study analyzed the expression patterns of polite expressions used by advanced Chinese learners of Korean when sending instant messengers. In addition, this study investigated the responses of Chinese Korean learners and native Korean speakers to the polite expression of messengers used by Chinese learners. Chinese Korean learners showed a high percentage of polite expressions through the use of honorific endings in instant messengers. In particular, the usage patterns of ‘Biumnida(ㅂ니다)’, ‘Biumnigga(ㅂ니까)’ accounted for 55.2% of the total ‘honorable endings’. I was found that Chinese learners use respectful endings of honorific words the most when expressing politeness. In particular, ‘Hapshoche(합쇼체)’, which is the highest grade, was often used. Instant messages sent by 10 Chinese graduate students to professors and seniors from September 2019 to March 2021 were analyzed. In order to understand the difference in politeness in expression of politeness between Chinese and Koreans, a 5-point scale perception survey was conducted on instant messages sent by Chinese learners to 30 Chinese and Koreans each. The average politeness scores of the two groups were compared and analyzed, and the survey results were examined focusing on low scores, high scores, and large differences in scores among them. Looking at the overall score, Koreans showed a wider range of recognition scores for politeness than Chinese. It was found that the Chinese gave a generous score to politeness compared to the Koreans. This means that even if Chinese people recognize and use certain expressions as polite expressions, Koreans can underestimate politeness. If you look at the expressions that Koreans consider to be low in politeness, most of the cases in which Chinese learners speak only their own business and take other people’s circumstances into account cannot be revealed in the message. These expressions may make the other person feel rude. In general, some think that native speakers lack politeness due to grammatical errors, but more importantly, it is due to the emotional attitude that Chinese learners contain in their messages. Through this, it can be interpreted that the criteria for judging Chinese and Korean politeness are different. In the case of most Chinese learners, they express their politeness centering on grammar. From the collected instant messages sent by Chinese learners, it can be seen that most Chinese learners mainly use ‘Hapshoche (합쇼체)’ when talking with professors. On the other hand, native Korean speakers do not simply consider grammatical factors regarding politeness through the results of recognition of the politeness level of native Korean speakers. There is a tendency to think that pragmatic elements such as feelings and emotions implied in the expression are more important than grammatical content. For this reason, there is a difference in the perception of politeness between advanced Chinese learners and native Korean speakers. (Ewha Womans University)

Yu, Min,Liu, Lei,Zhang, Bing-Lan,Chen, Qi,Ma, Xue-Lei,Wu, Yu-Ke,Liang, Chun-Shui,Niu, Zhi-Min,Qin, Xin,Niu, Ting Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12

Background: This study was performed to analyze the prognostic implications of pretreatment or preoperative thrombocytosis in women with gynecologic malignancies. Material and Methods: We surveyed 2 medical databases, PubMed and EMBASE, to identified all relevant studies. A total of 14 (n=3,490) that evaluated the link between thrombocytosis and 5-year survival were included. REVMAN version 5.1 was used for our analysis and publication bias was evaluated using the Begg's funnel plot and tested by STATA 11.0. Risk ratios (RRs) with 95% confidence intervals (CIs) generated by the random effect model were used to assess the strength of any association. Results: 709(20.3%) of the 3,490 patients exhibited thrombocytosis (platelet counts > $400{\times}10^9/L$) at primary diagnosis, and their mortality was 1.62-fold higher compared with the others (RR=1.62, 95%CI=[1.28-2.05], p<0.0001). Thrombocytosis failed to have a stronger effect on the survival of advanced patients of stages III to IV in our study (n=478, RR=1.29, 95% CI=[1.13-1.48], p=0.0003), nor in women with cervical cancer in stage IB (n=1371, RR=1.73, 95% CI=[1.71-2.58], p=0.007). In addition, when adjusted for different carcinoma, it was associated with worse prognosis for all except the ones with vulvar cancer (n=201, RR=0.43, 95% CI=[0.14-1.29], p=0.13). Conclusions: This meta-analysis indicated that thrombocytosis might be associated with a worse prognosis for patients with gynecologic malignancies but without specificity or sensitivity for the ones in advanced stage. When adjusted for different gynecologic malignancies, it showed a significant effect on survival of all except vulvar cancers.

Oviduct-specific Glycoprotein 1 Locus is Associated with Litter Size and Weight of Ovaries in Pigs

Niu, B.Y.,Xiong, Y.Z.,Li, F.E.,Jiang, S.W.,Deng, C.Y.,Ding, S.H.,Guo, W.H.,Lei, M.G.,Zheng, R.,Zuo, B.,Xu, D.Q.,Li, J.L. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.5

Oviduct-specific glycoprotein 1 (OVGP1) is implicated in playing a role in fertilization and early embryo development. In this study, we have obtained the sequence of intron 9 of OVGP1 gene in swine. Comparative sequencing of Meishan (a native Chinese breed) and Large White pig breeds revealed an A/T substitution at position 943. A PCR-EcoRI-RFLP assay was developed to detect this mutation. Polymorphism analysis in Qingping animals showed that pigs with BB genotype had lower number of piglets born alive (NBA) in multiple parities than pigs with AA (p<0.05) and AB genotype (p<0.01). In Large $White{\times}Meishan$ ($LW{\times}M$) $F_2$ offspring, the weight of both ovaries (OW) of the BB genotype was significantly lighter than that of AB (p = 0.05) and AA (p<0.01) genotypes. Analysis of the data also revealed that the mutation locus affected these two traits mostly by additive effects. These studies indicated that the polymorphism was associated with NBA and OW in two distinct populations and further investigations in more purebreds or crossbreds are needed to confirm these results.

Whole Brain Radiotherapy Combined with Stereotactic Radiotherapy Versus Stereotactic Radiotherapy Alone for Brain Metastases: a Meta-analysis

Duan, Lei,Zeng, Rong,Yang, Ke-Hu,Tian, Jin-Hui,Wu, Xiao-Lu,Dai, Qiang,Niu, Xiao-Dong,Ma, Di-Wa Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.2

Aim: This study was to evaluate the effect of whole brain radiation (WBRT) combined with stereotactic radiotherapy (SRS) versus stereotactic radiotherapy alone for patients with brain metastases using a meta-analysis. Materials and Methods: We searched PubMed, EMBASE, Cochrane Library from their inception up to October 2013. Randomized controlled trials involving whole brain radiation combined with stereotactic radiotherapy versus stereotactic radiotherapy alone for brain metastases were included. Statistical analyses were performed using RevMan5.2 software. Results: Four randomized controlled trials including 903 patients were included. The meta-analysis showed statistically significant lowering of the local recurrence rate (OR=0.29, 95%CI: 0.17~0.49), new brain metastasis rate (OR=0.45, 95%CI: 0.28~0.71) and symptomatic late neurologic radiation toxicity rate (OR=3.92, 95%CI: 1.37~11.20) in the combined group. No statistically significant difference existed in the 1-year survival rate (OR=0.78, 95%CI: 0.60~1.03). Conclusions: The results indicate that whole brain radiotherapy combined with stereotactic radiotherapy has advantages in local recurrence and new brain metastasis rates, but stereotactic radiotherapy alone is associated with better neurological function. However, as the samples included were not large, more high-quality, large-sample size studies are necessary for confirmation.

Adiponectin induced AMP-activated protein kinase impairment mediates insulin resistance in Bama mini-pig fed high-fat and high-sucrose diet

Miaomiao Niu,Lei Xiang,Yaqian Liu,Yuqiong Zhao,Jifang Yuan,Xin Dai,Hua Chen 아세아·태평양축산학회 2017 Animal Bioscience Vol.30 No.8

Objective: Adipose tissue is no longer considered as an inert storage organ for lipid, but instead is thought to play an active role in regulating insulin effects via secretion adipokines. However, conflicting reports have emerged regarding the effects of adipokines. In this study, we investigated the role of adipokines in glucose metabolism and insulin sensitivity in obese Bama mini-pigs. Methods: An obesity model was established in Bama mini-pigs, by feeding with high-fat and high-sucrose diet for 30 weeks. Plasma glucose and blood biochemistry levels were measured, and intravenous glucose tolerance test was performed. Adipokines, including adiponectin, interleukin-6 (IL-6), resistin and tumor necrosis factor alpha (TNF-α), and glucose-induced insulin secretion were also examined by radioimmunoassay. AMP-activated protein kinase (AMPK) phosphorylation in skeletal muscle, which is a useful insulin resistance marker, was examined by immunoblotting. Additionally, associations of AMPK phosphorylation with plasma adipokines and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed by Pearce's correlation analysis. Results: Obese pigs showed hyperglycemia, high triglycerides, and insulin resistance. Adiponectin levels were significantly decreased (p<0.05) and IL-6 amounts dramatically increased (p<0.05) in obese pigs both in serum and adipose tissue, corroborating data from obese mice and humans. However, circulating resistin and TNF-α showed no difference, while the values of TNF-α in adipose tissue were significantly higher in obese pigs, also in agreement with data from obese humans but not rodent models. Moreover, strong associations of skeletal muscle AMPK phosphorylation with plasma adiponectin and HOMA-IR index were obtained. Conclusion: AMPK impairment induced by adiponectin decrease mediates insulin resistance in high-fat and high-sucrose diet induction. In addition, Bama mini-pig has the possibility of a conformable model for human metabolic diseases.

A Multi-Dimensional Radio Resource Scheduling Scheme for MIMO-OFDM Wireless Systems

Li, Lei,Niu, Zhisheng The Korea Institute of Information and Commucation 2006 Journal of communications and networks Vol.8 No.4

Orthogonal frequency division multiplexing (OFDM) and multiple input multiple output (MIMO) technologies provide additional dimensions of freedom with spectral and spatial resources for radio resource management. Multi-dimensional radio resource management has recently been identified to exploit the full dimensions of freedom for more flexible and efficient utilization of scarce radio spectrum while provide diverse quality of service (QoS) guarantees. In this work, a multi-dimensional radio resource scheduling scheme is proposed to achieve above goals in hybrid orthogonal frequency division multiple access (OFDMA) and space division multiple access (SDMA) systems. Cochannel interference (CCI) introduced by frequency reuse under SDMA is eliminated by frequency division and time division between highly interfered users. This scheme maximizes system throughput subjected to the minimum data rate guarantee. for heterogeneous users and transmit power constraint. By numerical examples, system throughput and fairness superiority of the our scheduling scheme are verified.

Peng Song,Lei Cheng,Kangming Tian,Meng Zhang,Suren Singh,Dandan Niu,Bernard Prior,Nokuthula Peace Mchunu,Zheng-Xiang Wang 한국식품과학회 2020 Food Science and Biotechnology Vol.29 No.11

A new aminopeptidase (An-APa) was identified and biochemically characterized from Aspergillus niger CICIM F0215. It had maximal activity at 40 °C and pH 7.0 and exhibited a broad substrate specificity both on hydrophilic and hydrophobic amino acid residues at N-terminals. With An-APa hydrolysis for 1 h, the casein-pepsin and soybean protein isolates (SPI)-pepsin hydrolysates released both hydrophilic and hydrophobic amino acids and the hydrophobic amino acids having Q values (degree of hydrophobicity) greater than 1500 cal/mol were remarkably released. Leu, Ile, Phe, Tyr, Trp, Pro, Val and Lys in the casein hydrolysate after treatment with An-APa increased 18.61, 0.84, 11.35, 13.18, 3.34, 6.30, 7.46, and 8.19 mg/100 mL, respectively, and 19.72, 1.47, 18.37, 11.72, 4.61, 4.10, 8.13, and 5.85 mg/100 mL, respectively, in the SPI hydrolysate. Both accounted for 65.0% and 64.4% of total released free amino acids from casein and SPI hydrolysates, respectively. This indicated that An-APa could be potentially applicable in debittering protein hydrolysates.

An Improved Cancelable Fingerprint Template Encryption System Research

( Feng Wang ),( Bo Han ),( Lei Niu ),( Ya Wang ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.4

For the existing security problem based on Fuzzy Vault algorithm, we propose a cancelable fingerprint template encryption scheme in this paper. The main idea is to firstly construct an irreversible transformation function, and then apply the function to transform the original template and template information is stored after conversion. Experimental results show it effectively prevents the attack from fingerprint template data and improves security of the system by using minutiae descriptor to encrypt abscissa of the vault. The experiment uses public FVC2004 fingerprint database to test, result shows that although the recognition rate of the proposed algorithm is slightly lower than the original program, but the improved algorithm security and complexity are better, and therefore the proposed algorithm is feasible in general.
