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

In this paper, we introduce the mathematical resis-tance and examine its properties and consider the applications of mathematical resistance to conformal mappings. We obtain the theorems in the connection with "the mathematical resistance zero"and "the fundamental sequences".

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.

井伏二の漂流もの-素材的原點の小品との連から-

정보현 동아시아일본학회 2006 일본문화연구 Vol.20 No.-

井伏のいわゆる漂流ものでは素材が主題に關わっているものが多く、そういった素材が隨筆的小品に多々書かれている。「ジョン萬次郞漂流記」を始め、その一生を通して、多くの漂流ものの小說を書いている。それらを發表する前に、漂流に關して素材的な原點になるエピソードを多くの隨筆的小品に記している。が、これら漂流に關しての隨筆的な小品を一括して論じた硏究はまだ乏しい。本稿はそういった隨筆的小品群を考察し、小說の中にそれら素材をどう取り込んでいったか、井伏の關心の所在を確認し、井伏の執筆姿勢とその變化についても考えてみた。 その結果、井伏の交友や交流についての一貫した關心が考察された。一方、人物造型等の素材選擇が變化しているものもあり、戰前と戰後の漂流もので焦點が變わったことも明らかになった。 井伏が漂流ものに關心を持つようになったのは、單に旅が好きであったためであったと見られてきたが、昭和十年代の執筆當時の閉鎖的空間から井伏自身、作品を通して脫出をはかりたかったとも思われる。そして、徐々に漂流ものは共同體の內部を語るための裝置になり、閉鎖的社會を批判するためのものともなっていった。井伏は漂流ものの書き始めから、必ずしも共同體の現實に傍觀的ではなく、一貫して强い關心を持っていたと思われる。ただ、戰前は書き方が個人の追求を通して社會の現實を間接的に傳えていたのが、戰爭を經驗した井伏はそののち、より積極的に共同體の閉鎖的權力體制を告發するようになっていったようである。

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.

A NOTE ON EXTREMAL LENGTH AND CONFORMAL IMBEDDINGS

정보현 한국전산응용수학회 2010 Journal of applied mathematics & informatics Vol.28 No.5

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.
