Intelligibility of Korean-Accented English: Effects of Listener’s Familiarity

정보현,Hyun Kyung Miki Bong 한국영어교육학회 2021 ENGLISH TEACHING(영어교육) Vol.76 No.1

The present study investigate d Korean accented English (KoE) intelligibility and conducted experiments in Korea, Japan, and the USA to test the benefits of li ste ner ’s familiarity and ident ify the key phonological features of KoE. In the experiments, the participants were asked to transcribe the target (KoE) of 100 English statements each containing a target word representing one of the nine featur es. The tr anscription data were administered to four groups, depending up on the degree of KoE familiarity (length of exposure). The r esults indicate d that KoE was most intelligible to native English speakers with lower familiarity and least intelligible to the J apa nes e participants with low KoE familiar ity. Although the listeners’ familiarity d id not necessarily either facilitate or impede the intelligibility of KoE, the listeners with higher familiarity with KoE tend ed to recognize the voiced consonants of KoE better. The fin din gs also indicated which KoE characte ristics affected the overall intelligibility level, suggesting ways to prioritize KoE features in English language learning in Korean classrooms.

A Beam Performance Test for the 700-MHz and 1-MW Klystron

정보현,Jin-Seok Hong,Jae-Ha Jeon,Kie-Hyung Chung,Seung Jeong Noh,고승국 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.50 No.I

The 700-MHz and 1-MW klystron was designed and constructed by the Korea Accelerator and Plasma Research Association (KAPRA). A pulse power supply was used to manipulate the negative high voltage in the primary performance test for the klystron. After reinforcing the protection circuit, the test went on better than before. If a baking furnace is added to the klystron under fabrication, the ultra-high vacuum might be stabilized better than it is without the furnace. Various infrastructures, including the baking furnace, are under construction to develop the klystron

The Effects of Utilizing Language Learning Strategies in Teaching the Speech Act of Refusal

정보현,민수정,이종복 한국영어어문교육학회 2014 영어어문교육 Vol.20 No.3

This study examines the effects of strategies-based instruction on the refusal productions measuring the appropriateness using pre-test and post-test design. The aim of the study is to validate the strategies for speech acts acquisition suggested by Cohen (2005). The twenty Korean EFL learners with homogeneous level of English proficiency in undergraduate course participated in this study. The participants were given three instructional treatments which were modeled after taxonomy of strategies for speech act acquisition by Cohen (2005), namely, (1) strategies for the initial learning of speech acts, (2) strategies for using the speech act material and (3) metapragmatic considerations. Pre-test and post-test were administered a week before and after the teaching sessions to illustrate refusals with consideration of the social status between speaker and hearer. With collected refusal responses, two raters evaluated appropriateness of refusals according to a previously developed evaluation rubric (Taguchi, 2006). Based on the data from the refusal appropriateness evaluation score of the participants, a paired sample t-test was implemented in order to measure the effects resulted by three teaching sessions. The results demonstrate that there was a positive effect on the refusal appropriateness as the mean scores were positively increased in all three various social statuses.

흰쥐 턱밑샘에서 fluoxetine 투여에 의한 침분비 및 muscarinic acetylcholine receptor M3 발현 감소

침분비저하, 구강건조증 및 침 성분의 변화를 포함한 비정상적인 침분비는 항우울제복용과 관련된 중요한 부작용이다. 선택적 세로토닌 재흡수 억제제(SSRI) 항우울제 또한 이러한 부작용을 가지고 있다. 하지만 SSRI에 의한 침분비저하 기전과 항콜린성 작용은 완전히 밝혀지지 않았다. 본 연구에서는 fluoxetine 의 만성 투여 후 쥐의 침샘에서 침분비와 콜린성 신호 단백질 수치의 변화를 확인하였다. 동물은 정상군, 저농도경구투여군(20 mg/kg p.o.), 고농도경구투여군(40 mg/kg p.o.), 저농도복강투여군(20 mg/kg i.p.) 그리고 고농도복강투여군(40 mg/kg i.p.)으로 구분하였다. 4주 동안 fluoxetine 투여 후, 침을 수집하여 침분비량을 측정하였다. 후에 침샘 조직을 적출하여 muscrinic acetylcholine receptor M3 (mAchR M3) 와aquaporin5 (AQP5) 항체를 이용하여 단백질 정량을 하였다. 그 결과 복강투여군에서 침 분비량의 감소가나타났지만, 경구투여군에서는 나타나지 않았다. 이 감소 패턴은 mAchR M3 와 AQP5 단백질 수치에서도유사하게 나타났다. 이러한 결과는 fluoxetine에 의한 침분비저하가 항콜린성 작용과 관련이 있음을 시사한다.

Language Learning Motivation and Its Impact on Speech Act of Refusal

정보현,민수정 한국영어교과교육학회 2014 영어교과교육 Vol.13 No.1

This study aims to elaborate on Korean EFL learners’ motivational constructs and to examine how they are interrelated with their refusal speech act realization. The data consisted of Korean college student questionnaire and discourse completion task responses. A factor analysis was applied to define the motivation constructs, and a stepwise multiple regression test was carried out to measure the relationship between motivation and the appropriateness of the refusal speech acts. The results showed that Korean EFL learners’ motivation depends upon four factors: Ego-enhancement, stimulation, exploration, and manipulation. The stimulation and exploration constructs of motivation in particular were found to have a statistically significant relation with the speech act of refusal. The results suggest that the language learning motivational factors should also be taken into account of in teaching and learning the proper use of speech act in English.

Let D be a plane domain whose boundary consists of n compo-nents and C₁,C₂ two boundary components of D. We consider the family F1 of conformal mappings f satisfying f(D) ⊂ {1< lwl< μ(f)}, f(C₁) ={lwl = 1}, f(C₂) = {lwl = μ(f)}. There are conformal mappings g0, g1(∈F₁) onto a radial and a circular slit annulus respectively. We obtain the following theorem,[수식]And we consider the family Fn of conformal mappings □ from D onto a covering surfaces of the Riemann sphere satisfying some conditions. We obtain the following theorems,[수식]

Design, Fabrication and Test of the Steering Magnet for the KOMAC Beamline

정보현 한국물리학회 2015 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.67 No.8

The Korea Multi-purpose Accelerator Complex (KOMAC) is operating a 100-MeV proton linac. The beamline facility of the KOMAC has both a 20-MeV beam and a 100-MeV beam for users. Steering magnets are added to the beamlines to adjust the position of the beam on the target. The uniformity and the harmonics of the magnetic field are computed by using the Poisson code, and the integrated magnetic field is computed by using the CST EM Studio. The designed magnets were fabricated, and the field’s uniformity and the integrated field were measured. The designed and fabricated steering magnets were characterized, and the results are presented in this paper. The results are expected to improve the beam performance, in particular, accurate delivery to the target.
