The production of tone 3 by advanced Korean learners of Mandarin

Yuping Fu,이용철 경희대학교 언어정보연구소 2022 언어연구 Vol.39 No.1

This study examined the differences in tone 3 productions between advanced Korean learners and native speakers of Mandarin by implementing three analyses: acoustic, frequency, and distance metric analyses. Based on the acoustic analyses, the advanced learners exerted more articulatory effort in producing tone 3, regardless of the syllable positions within disyllabic words. Compared to the native speakers, the production of tone 3 by the learners was longer in duration, more intense, and displayed steeper falling and rising pitch movements—these are all salient cues for tone 3 as a dipping pitch contour. The native speakers, however, economized articulatory effort in their tone 3 productions. They did not lower the pitch target of tone 3, nor did they employ the steep falling and rising pitch movements to the same extent as the advanced learners. According to the frequency analyses, the native speakers yielded more variants of half-T3 than the advanced learners in both syllables of the disyllabic words. Finally, the distance metric analyses revealed that the advanced learners’ pitch contours were more different from those of the native speakers in syllable 2 than in syllable 1. Consistent with previous work, our results emphasize that the learners’ dipping pitch contour for tone 3 stems from the widespread second language pedagogy of Mandarin tones, where tone 3 is predominately described as a dipping tone. Learners, therefore, must understand and become competent using varied tone 3 patterns before attaining native-like or near-native competence.

Visualising Corpus-based Discourse Studies from 1995 to 2019 by Using a Bibliometric Analysis

Yuping Fu,Yuanzhu Liang,Zongjie Zhang,Yong-cheol Lee 한국외국어교육학회 2021 Foreign languages education Vol.28 No.2

This study employed a bibliometric method to visualize the evolution of corpus-based discourse studies between 1995 and 2019, with a total of 2,174 English-language documents and their 83,184 references collected from Scopus, the Social Science Citation Index, and the Arts & Humanities Citation Index. Co-citation analysis of the predominant authors, references, and publication sources disclosed that the field has expanded over the past 25 years from primary pattern analysis of descriptive and functional grammar to principal investigations of interdisciplinary issues, some of which are central to pragmatics and sociolinguistics. This shift of research focus is also evidenced by keyword analysis. Scholars have been progressively more fascinated by such social issues as news discourse, business discourse, gender and language, and identity. Some emerging topics like social media, media discourse, legal discourse, and the metadiscourse interpersonal model may represent research hotspots and trends in this area. Bibliometric approaches play an important role in providing hands-on evidence-based comparisons and visualizations of previous research outputs using different time bands.

Invasive Fungal Infections: Diagnosis and Treatments in China

Yuping Ran 대한의진균학회 2008 대한의진균학회지 Vol.13 No.3

The body location and clinical appearance of fungal infections depends on the fungal virulence, infectious route and host immunological state. The result being that patients with mycoses consult with different clinical departments. The diagnosis of mycoses is based on the detection of fungal elements such as hyphae and/or yeast cells from the involved tissues. Isolation of the fungus is the precondition for species identification and antifungal treatment. To think clinically and to emphasize the mycology is the basic consideration of medical mycology research. Mycologists play a key role in the collaboration between the clinical and laboratory aspects. The clinician always wants to know what the fungus is and how to treatment the mycosis. Fungal pathogens are often stealthy and difficult to detect in infected patients during the early stages of the diseases and this is when therapies would be the most effective. Routine techniques commonly employed in the detection of fungal diseases including microscopic examination, culturing and serology are seriously hampered by lengthy waits of times for results and low accuracy. The clinician may want prophylaxis or to use empirical antifungal treatment to see if it does/does not work. The problem is that some of the patients do not respond to the antifungal treatment, because the doctor lacked sufficient evidence of fungus infection to give the doctor confidence to continue treatment. Accurate and early diagnosis of fungal diseases is critical for managing mycotic diseases. This is usually done by direct microscopic examination (DME) of KOH preparations. Good specimens are the key point that directly affects the quality of microscopic evidence and culture. The most important aspect is culturing samples on different media with or without chloramphenicol and cycloheximide and incubated at room temperature and 37℃. Early treatment could save a patient's life. We start treatment at the time we have the proof of fungal infection, i.e., KOH positive. Itraconazole, fluconazole, terbinafine, amphotericin B or its liposome form, can be used alone or in combination based on the fungal species involved and the site of infection.

Optimal Diversity-Multiplexing Tradeoff of MIMO Multi-way Relay Channel

Yuping Su,Ying Li 한국전자통신연구원 2013 ETRI Journal Vol.35 No.5

A MIMO multi-way relay channel with full data exchange in which K users exchange messages with each other via the help of a single relay is considered. For the case in which each link is quasi-static Rayleigh fading and the relay is full-duplex, the fundamental diversity-multiplexing tradeoff (DMT) is investigated, and we show that a compress-and-forward relay protocol can achieve the optimal DMT.

Effects of Task-Based Intercultural Instruction on EFL Students’ Intercultural Competence and Language Abilities

Yuping Sun,Na-Young Kim 한국영어교과교육학회 2021 영어교과교육 Vol.20 No.4

This study was designed to investigate the effects of Task-Based Intercultural Instruction (TBII) on Chinese EFL students’ intercultural competence and language abilities, focusing on reading and writing. A total of 102 freshmen at a university in China participated in this study. They were randomly divided into one experimental group (n = 50) and one control group (n = 52). During the 16-week experimental period, both groups received Task-Based Language Teaching (TBLT), though the experimental group was integrated with intercultural instruction while the control group did not receive intercultural instruction. Before and after the experimental period, there were pre- and post-surveys on intercultural competence and pre- and post-tests regarding language abilities. Paired sample t-tests between the pre- and post-surveys and pre- and post-tests were administered to determine the effects of TBII. Independent t-tests were also performed to compare the differences between the two groups regarding intercultural competence and reading and writing abilities. The findings revealed statistically significant mean score changes in the participants’ intercultural competence in the experimental group. Furthermore, both groups showed significant improvements regarding reading and writing abilities. Based on these findings, pedagogical suggestions are made for EFL learning.

Tunable All-optical Wavelength Conversion of a Femtosecond Pulse Based on Cascaded (2) SHG + DFG Interactions

Yuping Chen,Feng Lu,Wenjie Lu,Xianfeng Chen 한국물리학회 2009 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.55 No.3

Based on cascaded second harmonic generation and difference-frequency generation interactions and employing a type-I quasi-phase-matching technique in MgO-doped periodically poled lithium niobate, we realized wavelength conversion of a 70-femtosecond pulse without pulse broadening at the group-velocity-matching wavelength. Due to the 25 nm bandwidth of second harmonic generation obtained in a 20-mm-long crystal, we convert a 70-fs pulse centered at 1.56 μm by using a continuous-wave signal at 1.60 μm. No obvious distortion or broadening of the converted pulse was observed.

Test for the covariance matrix in time-varying coefficients panel data models with fixed effects

Yuping Hu,Sanying Feng,Jing Zhao 한국통계학회 2021 Journal of the Korean Statistical Society Vol.50 No.2

This paper proposes tests for the null of sphericity and identity matrix for nonparametric time-varying coefficient panel data models with fixed effects. Firstly, based on the local linear smoothing technique, the estimators of the unknown coefficient functions and model residuals are obtained. Secondly, proper test statistics are proposed aiming at tests for sphericity or identity matrix with a large number of cross sectional units and time series observations. In addition, the limiting distributions of the proposed test statistics are derived based on random matrix theory. At last, some simulation studies are conducted to examine the finite sample performance for the proposed test statistics and a real data example is analyzed.

Yuping Li,Li-Hua Yao,Guan-Jie Wu,Xiao-Fang Pi,Yan-Chun Gong,Ruo-Shong Ye,Chen-Xi Wang 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.6

Novel small-molecule polysaccharide fractions,named POP II and POP III, were purified from Portulacaoleracea L. with average Mw values of 9.25 and 8.03 kDa,respectively. Monosaccharide analysis revealed that POP IIwas composed of Rha, Ara, Man, Glc, and Gal with molarratios of 1: 1.42: 0.44: 0.88: 1.59. POP III was composedof Rha, Ara, Glc, and Gal with molar ratios of 1: 1.16:0.23: 0.59. The antioxidant activities of the fractions wereevaluated using cell-free and cell-mediated radical generatingsystems. POPII and POP III possessed strong antioxidantactivities in both systems. The 2 novel polysaccharidefractions extracted from P. oleracea L. can be developed asnatural antioxidants for treatment of free radical-relateddiseases.
