I think and I don’t know as Stance-Taking Markers among Korean Speakers of English

민수정,정규태 한국현대영어영문학회 2024 현대영어영문학 Vol.68 No.1

Min, Sujung · Jung, Kyutae. “I think and I don’t know as Stance-Taking Markers among Korean Speakers of English.” Modern Studies in English Language & Literature 68.1 (2024): 387-407. This study investigates the use of I think and I don’t know as stance-taking markers among Korean speakers of English in English as a lingua franca (ELF) interaction. Previous research on the expressions of stance through I think and I don’t know constructions has suggested that they differ in ELF and L1 English discourse because of the specific nature of the ELF interactional situation in which the speakers’ different L1s may evoke ELF-specific patterns of stance-taking (Baumgarten & House, 2010). English in Korea is regarded as the most important foreign language, so Korean society is a proper context for research on ELF. The analysis of I think and I don’t know and their co-occurrences with syntactic and discourse phenomena in the elicited conversation data shows that their distributions and functional profiles of the two stance-taking devices are similar to those in other ELF discourse.

민수정,이시우,최병렬,이시혁,권덕호 한국응용곤충학회 2014 Journal of Asia-Pacific Entomology Vol.17 No.4

Nilaparvata lugens Stål is one of the important migratory pests of rice paddy fields in Korea. Resistance levels tonine insecticides were monitored in 12 local strains and correlation analysis was conducted to determine crossresistancerelationships among the tested insecticides. The local strains revealed 1.3- to 28.0-, 1.6- to 6.0-, 2.8- to237.0-, 0.6- to 0.9-, and 0.7- to 1.3-fold resistance to carbamates, organophosphates, neonicotinoids, fipronil andetofenprox, respectively. Organophosphate insecticides revealed moderate correlations with benzofuranylmethylcarbamate (r = 0.566–0.614, p N 0.01). Three neonicotinoids were not correlated with each other, butimidacloprid and clothianidin were moderately correlated with several benzofuranyl methylcarbamate and organophosphateinsecticides (r= 0.590–0.705, p N 0.05), indicating that unknown common factors (such as detoxificationenzymes) might contribute to resistance to both insecticides. Fipronil and etofenprox exhibited lowlevels of resistance and cross-resistance with other insecticides, suggesting their potential as an effective insecticidefor field application. Resistance level monitoring and correlation analysiswould be valuable for the selectionof appropriate insecticides to control insecticide-resistant N. lugens, a typical migratory pest in Korea.

EFL Learners’ Use of the Modals and Quasi-Modals of Obligation and Necessity

민수정,이종복 한국영어어문교육학회 2012 영어어문교육 Vol.18 No.3

This study examines the use of the modals and quasi-modals of obligation and necessity, which involves the layering of must, should, have (got) to, got to, and need to in a corpus of cross-cultural communication between EFL learners. The study compares the EFL learners’ corpus with a sub-corpus of ICE-GB in terms of token counts and semantic/functional distributions because International Corpus of Standard varieties of English serves as common reference points for international comparison of varieties of English. The results showed that must, should, and have to were the main players in both the corpus of EFL learners and that of native speakers. However, some discrepancy exists between EFL learners’ corpus and the native speakers’ corpus in the use of the modals and quasi-modals of obligation and necessity. Compared to the corpus of native speakers, the corpus of EFL learners was distinctively different in the relative unpopularity of have to and in the comparative popularity of must particularly for root meaning. Suggestions were made for using computer corpora in understanding EFL learners’ language use. And pedagogical implications were made for teaching English modality considering the current usage of the modals and quasi-modals in Standard varieties of English and helping the students develop pragmatic competence.

한국어와 영어 발화에 나타나는 휴지(pause)의 음성학적 비교분석

민수정,정영진 한국언어과학회 2010 언어과학 Vol.17 No.4

Suprasementals or suprasemental features such as stress, pitch, intonation and pause play an important role in spoken communication. This study assumes that the differences in suprasementals between English and Korean may interfere with the Korean EFL learners in proper understanding of English. Thus, the object of this study is to show differences in pause between English and Korean by analyzing both inter-sentential and intra-sentential pauses. For the purpose, two groups of data were selected: one, the dialogues and speeches from TOEIC test and the other, those from TOPIK test. The results show that pause in Korean is relatively longer than in English in both inter- and intra-sentential levels, and pause is not exactly consistent with the syntactic and semantic units in both languages

Repetition as a Meaning Making Strategy in ELF Context

민수정 팬코리아영어교육학회 2015 영어교육연구 Vol.27 No.2

English has become the chosen medium to facilitate successful communication among people of different linguistic and cultural backgrounds. Of fundamental importance is how the speakers of English of varying degree of proficiency achieve mutual understanding in this medium. This study addresses this by offering some inquiries into the process of meaning making or meaning negotiation in English as a lingua franca (ELF) context with particular emphasis on a single involvement strategy of repetition used to achieve mutual understanding. Using a conversational analytic framework, this paper investigates how the participants in interactions achieve shared understanding through meaning negotiation and how they strategically employ repetition to address and resolve understanding problems when they occur and achieve their goal. Fifteen hours of transcribed audio recordings of naturally occurring spoken interactions in ELF context between speakers of a range of first languages and cultural backgrounds were examined. The data analysis shows that ELF communication is successful as the participants make proper use of repetition strategy.

EFL Learners’ Use of the Modals of Possibility in Cross-Cultural Communication: A Corpus-Based Account

민수정 새한영어영문학회 2012 새한영어영문학 Vol.54 No.1

This study aims to examine the use of the modals of possibility, can, may, could, and might in a corpus of cross-cultural communication between EFL learners. The study compares the EFL learners’ corpus with a sub-corpus of ICE-GB in terms of token counts and semantic/functional distributions. The results showed that can has the highest frequency and proportion of the modals of possibility in both the NNC and the NC. However, some discrepancy exists between EFL learners’ corpus and the native speakers’ corpus in the use of the modals of possibility. EFL learners used relatively smaller number of the modals of possibility in terms of total tokens. EFL learners tend to underuse may. Both could and might were also much less used in EFL learners’ communication than in the native speakers. Suggestions were made for using computer corpora in understanding EFL learners’ language use and helping them develop communicative competence.

A Descriptive Analysis of Korean EFL Learners’ Refusals with Implication for Second Language Pragmatics

민수정,이종복 한국현대언어학회 2013 언어연구 Vol.28 No.4

Among the speech acts we engage in daily, refusals are one of face-threatening acts because interlocutors’ negative face can be threatened. In light of cross-cultural communication, therefore, even for the fluent EFL learners, the inappropriate use of refusals in some situations often results in interpersonal communication breakdown. Relying on the two means of data collection from 20 Korean EFL learners and 20 native English speakers, this study examines how the Korean EFL learners perform refusal speech act when they refuse invitations and how their speech act of refusals differ from those of native speakers of Standard varieties of English. Pedagogical implications were made helping the EFL learners develop pragmatic competence for successful communication.

The Progressive Aspect in EFL Asian Context and the ESL/EFL Continuum

민수정 한국현대언어학회 2014 언어연구 Vol.30 No.3

The extension of the progressive aspect has been widely discussed as a feature of non-native varieties of English as representing either structural variation or semantic extension to new contexts. Responding to calls to approach varieties of English as a native (ENL), second (ESL) and foreign (EFL) language in an integrated way, this paper reports on a case study of the progressive aspect in English used in Korea and Japan which belong to the Expanding Circle. This study analyzed approximately 1260 tokens of progressive in three registers: real time online discussion, academic writing and news reportage. The results were compared with the data from ENL and ESL varieties from van Rooy (2014) and Edwards (2014). The results show no strict divide between the ESL varieties and English used in Korea and Japan, which displayed characteristics of both EFL and ESL. The results also reveal that the progressive is used more frequently in spoken register than written one.

Countability of Mass Nouns among the EFL Learners in Asian Context

민수정 한국현대언어학회 2014 언어연구 Vol.30 No.1

This study examined variation in the countability of mass nouns like information and knowledge among the EFL learners in Korea and Japan which belong to the Expanding Circle. The countability of nouns is frequently cited as a marker of nativeness which distinguishes Inner Circle norms in TESOL from the Outer and Expanding Circle usage. The study inspected the countability of mass nouns in a corpus of cross-cultural communication between EFL learners and compared the results with the data from the other varieties of English used in the Outer and Expanding Circles. Based on the analysis, the study evaluated potential causes of variation, investigating differences between Outer and Expanding Circles. This study notes there is notable and widespread countable use of nouns that are generally non-count in Inner Circle Englishes, but such usage is highly infrequent overall. There appears to be greater variation in the Outer than the Expanding Circle. Based on the results, some implications about lexico-grammatical variation in lingua franca use of English and the plurilithic nature of English.

민수정,강하라,이병채,서범경,노창현,홍상범,정재학 한국물리학회 2021 새물리 Vol.71 No.9

In this study, a nanomaterial-loaded plastic scintillator that could be used in decommissioning nuclear facilities was developed and its applicability was evaluated. Plastic detectors with low atomic number are mainly used for alpha and beta measurements. However, by adding a CdTe nanomaterial with a high atomic number to the plastic matrix, Such detecture can be used for gamma-ray detection through mechanisms such as improving the interaction rate with photons and reducing the electron loss rate through wavelength shift or band gap control. In this study, to evaluate the performance of a plastic scintillator containing CdTe nanomaterials we compared, the measurement results obtained using a 60Co radioactive source to those obtained using a commercial plastic scintillator. The results showed that the relative efficiency of the CdTe-loaded plastic scintillator for 60Co detection compared to that of a commercial plastic scintillator was 132% on average. In particular, as a result of calculating the count ratio the effect of the CdTe nanomaterial was observed in the Compton energy region of 60Co. Finally, a plastic detection system containing a nanomaterial can contribute to reductions in both the decommissioning costs and worker exposure through quick and rapid measurements at nuclear facilities. 본 연구에서는 해체과정에서 발생되는 다양한 해체폐기물을 현장에서 현장 검사 및 분류를 수행하기위해 나노 물질 기반 플라스틱 섬광체를 개발하였고, 이를 현장 측정 검출기로서의 가능성을 평가하기위해 상용플라스틱 검출기와 계측 성능을 비교 평가하였다. 낮은 원자번호로 구성되어 있는 플라스틱매트릭스에 고 원자번호의 CdTe 나노 물질을 첨가함으로써 광자와의 반응률 향상, 파장 시프트 또는밴드갭 조절을 통한 전자 손실률 감소 등의 메커니즘을 통해 감마선 검출에 활용 가능하다. 본 연구에서는60Co 방사 선원을 활용하여 CdTe 나노 물질이 함유된 플라스틱 섬광체의 성능을 상용플라스틱 섬광체와비교 분석하였다. 그 결과, 상용 플라스틱 섬광체 대비 CdTe가 함유된 플라스틱 섬광체의 상대 효율이평균 132% 로 분석되었다. 특히, Count ratio를 산출한 결과, 60Co의 콤프턴 에너지 영역에서 CdTe 나노 물질의 효과가 관찰되었다. 본 연구결과를 기반으로, 나노 물질이 함유된 플라스틱 검출 시스템을원자력시설 해체 분야에 적용한다면, 빠르고 신속한 측정을 통해 해체 비용 및 작업자 피폭 저감에 기여할수 있을 것으로 판단된다.
