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.
Compositional meanings in Chinese subtitle translation: A multimodal analysis of Mulan
( Yuping Chen ),( Wei Wang ) 이화여자대학교 통역번역연구소 2017 T&I review Vol.7 No.-
While roles of semiotic interplay in subtitle translation have been widely acknowledged, scant research has been done to examine how visual and verbal modes really interact with each other to produce a coherent and cohesive whole of a subtitled film. Drawing on the concepts of compositional meanings and semiotic cohesion informed by systemic functional linguistics, this paper conducts a multimodal analysis of the Chinese subtitles in an English language film Mulan, focusing on examining compositional meanings from three aspects: types, functions of semiotic interrelations and impacts on linguistic parts of subtitles. This paper finds that co-referentiality (Halliday and Hasan 1985) is the most predominant cohesive relation between subtitle and image, which exerts more impacts on linguistic parts relating to identification of subtitles. This finding can be seen in two implicit encoding devices of anaphora and cataphora. It suggests that a subtitling unit is not limited to a filmic unit of shot, but goes far beyond it, which contributes to maintaining the narrative flow in subtitled films. These findings deserve to be further explored in examination of subtitling practice and construction of theoretical models in this growing field of research.
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.

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.

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.
