Yun Bai and Jaewoo Shim. 2021. English Pronunciation Self-efficacy Sources and Pronunciation Proficiency of Chinese College Learners. Studies in Modern Grammar 109, 105-126. The purpose of this study is to investigate the relationship between the four sources of English pronunciation self-efficacy and English pronunciation proficiency of Chinese college learners of English. A sample of 429 English majors at a college in China was selected. The test scores from a read-aloud task were used as the measure of subjects’ English pronunciation proficiency. The questionnaire was used to collect the data of four English pronunciation self-efficacy sources. The Pearson correlations showed that the four sources were correlated significantly with English pronunciation proficiency. The multiple regression analysis showed that 45% variance in English pronunciation proficiency was explained by the linear combinations of the four sources; however, the nominal variable of gender was not statistically significant in explaining the variance in English pronunciation proficiency. Overall, the significant relationship between English pronunciation self-efficacy sources and English pronunciation proficiency was observed in the present study. Pedagogical implications for teaching English pronunciation were discussed based on the results.

Bai, Yun-Lu,Zhou, Bing,Jing, Xiao-Yue,Zhang, Bin,Huo, Xiao-Qing,Ma, Chao,He, Jian-Miao Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.10

Objective: To evaluate the predictive value of GST gene polymorphisms with regard to prognosis of breast cancer patients receiving neoadjuvant chemotherapy. Methods: A total of 159 patients were included in our study between January 2005 and January 2007. All the patients were followed up until January 2012. Genotyping was based upon the duplex polymerase-chain-reaction with the PCR-CTPP method. Results: Patients with null GSTM1 and GSTP1 Val/Val genotypes had significantly had better response rates to chemotherapy when compared with non-null GSTM1 and GSTP1 Ile/Ile genotypes (OR=1.96 and OR=2.14, respectively). Patients with the GSTM1 null genotype had a longer average survival time and significantly lower risk of death than did those with non-null genotypes (HR=0.66). Similarly, those carrying the GSTP1 Val/Val genotype had 0.54-fold the risk of death of those with GSTP1 Ile/Ile (HR=0.54). Conclusion: A significant association was found between GSTM1 and GSTP1 gene polymorphisms and clinical outcomes in breast cancer cases.

Background/Aims: Drug-induced liver injury (DILI) is a frequent cause of pediatric liver disease; however, the data on DILI are remarkably limited. Methods: All 69 children hospitalized with DILI between January 2009 and December 2011 were retrospectively studied. Results: A total of 37.7% of the children had medical histories of respiratory infection. The clinical injury patterns were as follows: hepatocellular 89.9%, cholestatic 2.9%, and mixed 7.2%. Liver biopsies from 55 children most frequently demonstrated chronic (47.3%) and acute (27.3%) hepatitis. Hypersensitivity features, namely, fever (31.9%), rash (21.7%), and eosinophilia (1.4%), were found. Twenty-four children (34.8%) developed chronic DILI. Antibiotics (26.1%) were the most common Western medicines (WMs) causing DILI, and the major implicated herbs were Ephedra sinica and Polygonum multiflorum. Compared with WM, the children whose injuries were caused by Chinese herbal medicine (CHM) showed a higher level of total bilirubin (1.4 mg/dL vs 16.6 mg/dL, p=0.004) and a longer prothrombin time (11.8 seconds vs 17.3 seconds, p=0.012), but they exhibited less chronic DILI (2/15 vs 18/39, p=0.031). Conclusions: Most cases of DILI in children are caused by antibiotics or CHM used to treat respiratory infection and present with hepatocellular injury. Compared with WM, CHM is more likely to cause severe liver injury, but liver injury caused by CHM is curable. (Gut Liver 2015;9:525-533)

A Study of the Effects of China’s TBT Notifications on Korean Exports

Bai Yun,오근엽 한국국제경제학회 2023 International Economic Journal Vol.37 No.1

Since China joined the World Trade Organization (WTO) in 2002, the number of technical barriers to trade (TBT) notifications has increased rapidly. This study investigates the impact of China’s imposition of TBTs on the exports of Korean manufacturing-industry from 2002 to 2014. We focus on the following aspects: exports in terms of valueadded, a comparison of exports of final goods with exports of intermediate goods, and specific trade concerns (STCs). Our findings are as follows. First, China’s TBTs have an insignificant impact on Korean manufacturing exports to Chinawhenweinvestigate the whole manufacturing industry sector. Second, as a result of analyzing final goods and intermediate goods separately,wedo not find a significant effect of TBTs on the export of intermediate goods, whereas they have negative effects on the export of final goods. This is in line with our expectations that China does not want to restrict the import of intermediate goods. Third, further analysis of the relationship between exports and TBT STCs is conducted. However, we find no additional negative effect of TBT STCs on exports. Fourth, the impact of TBTs on exports in value-added terms does not seem to differ from the impact on total gross exports.

The Relationship between Pronunciation Self-Efficacy Sources and Pronunciation Learning Strategy Use

Yun Bai,Jaewoo Shim,Heechul Lee 한국영어교과교육학회 2021 영어교과교육 Vol.20 No.3

The purpose of this study is to investigate the relationship between the subjects’ four sources of English pronunciation self-efficacy and their pronunciation learning strategy use. The subjects were 429 Chinese English majors from a university in China. The sub-dimensions of the two instruments were first validated through a confirmatory factor analysis (CFA). The group variable (i.e., the three clusters identified by the k-means cluster analysis) was the dependent variable, and the four sources of pronunciation self-efficacy were entered as the independent variables in a discriminant analysis. The results revealed that three out of the four sources of English pronunciation self-efficacy (i.e., ‘enactive mastery experience’, ‘vicarious experience’, and ‘verbal persuasion’) contributed to differentiating the subjects into the three clusters (groups) of high-, low-, and medium users of pronunciation learning strategies, with an overall classification accuracy ratio of 61.6%. Some implications concerning consciousness-raising activities, task repetition, and corrective feedback for teaching English pronunciation were discussed based on the results of the study.

Correction strategy of fuel injection quantity during pilot-main injection for common rail system

Yun Bai,Yuanqi Gu,Qi Lan,Liyun Fan,Xiuzhen Ma 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.6

Common rail system is a key technology of energy saving and emission reduction for modern diesel engines. Multiple injection, as one of the most interesting features of common rail system, allows both optimal fuel consumption and exhaust emissions. In order to explore the method for controlling the fluctuation of fuel injection quantity during multiple injection, experiments have been carried out in this paper, focusing on pilot-main injection. The high pressure fuel circuits of the system have been equivalent to a spring-mass vibration system. Comparison with the experiment shows that the proposed fluctuation equation can reasonably predict the fluctuation characteristics of main injection quantity with pilot-main injection interval. The correction control strategy for the main injection quantity fluctuation has been proposed, in which the relative damping coefficient, rail pressure, pilot-main injection interval and main injection pulse width are chosen as the input variables. The experimental results with different rail pressure and main injection quantity show that the fluctuation of injection quantity during pilotmain injection can be controlled effectively by the proposed correction strategy. The maximum average fluctuation of main injection quantity decreases by as much as 44.66 %.
