Do Koreans Process Verbs Faster Than Nouns in English?: Examination of Noun-Bias Hypothesis

이고운 한국영어학학회 2024 영어학연구 Vol.30 No.2

This study investigates how linguistic parameters (e.g., word order and null subject) influence word processing. Fourteen Korean-speaking subjects and ten English-speaking subjects participated in a lexical decision test in which the participants were asked to decide the lexicality of the stimuli. The result demonstrated that Koreans responded more accurately and faster to verbs than nouns compared to Americans. Also, Koreans benefited more from word frequency than native speakers. Thus, this study was able to find firm evidence to support language-specific biases in word processing.

An acoustic and perceptual investigation of the vowel length contrast in Korean

이고운,신동진 한국음성학회 2016 말소리와 음성과학 Vol.8 No.1

The goal of the current study is to investigate how the sound change is reflected in production or in perception, and what the effect of lexical frequency is on the loss of sound contrasts. Specifically, the current study examined whether the vowel length contrasts are retained in Korean speakers’ productions, and whether Korean listeners can distinguish vowel length minimal pairs in their perception. Two production experiments and two perception experiments investigated this. For production tests, twelve Korean native speakers in their 20s and 40s completed a read-aloud task as well as a map-task. The results showed that, regardless of their age group, all Korean speakers produced vowel length contrasts with a small but significant differences in the read-aloud test. Interestingly, the difference between long and short vowels has disappeared in the map task, indicating that the speech mode affects producing vowel length contrasts. For perception tests, thirty-three Korean listeners completed a discrimination and a forced-choice identification test. The results showed that Korean listeners still have a perceptual sensitivity to distinguish lexical meaning of the vowel length minimal pair. We also found that the identification accuracy was affected by the word frequency, showing a higher identification accuracy in high- and mid- frequency words than low frequency words. Taken together, the current study demonstrated that the speech mode (read-aloud vs. spontaneous) affects the production of the sound undergoing a language change; and word frequency affects the sound change in speech perception.

한국 청년의 비만 및 고도비만 관련 요인 - 건강행태, 정신건강, 만성질환 중심으로: 2019년 지역사회건강조사 자료

이고운,Lee, Kowoon 한국융합학회 2021 한국융합학회논문지 Vol.12 No.9

본 연구의 목적은 우리나라 청년의 비만, 중등도비만, 고도비만의 유병률을 분석하고 관련 요인을 파악하는 것이다. 2019년 지역사회건강조사 자료 중 20-39세 총 50,095명을 분석에 활용하였다. 카이제곱검정과 다중로지스틱 회귀분석을 실시하였다. 연구 결과 청년 인구의 비만은 23.60%, 중등도비만은 5.86%, 고도비만은 1.31%였다. 대상자의 일반적 특성 중 20대, 남성, 저소득, 낮은 교육수준, 기혼이 모든 비만 단계와 관련있었다. 현재흡연, 고위험음주, 신체활동, 건강생활실천, 주관적 건강감, 삶의 질, 스트레스, 우울감, 만성질환 유병여부가 청년 비만을 증가시켰다. 건강검진, 주관적 건강감, 삶의 질, 스트레스, 우울감, 만성질환 유병여부가 청년 고도비만을 증가시켰다. 본 연구 결과를 바탕으로 청년 비만에 관심을 기울이고 비만 단계별 특성을 고려한 중재 프로그램이 개발 및 제공되어야 할 것이다. The aim of the study was to assess the prevalence of young adults obesity, morbid obesity and severe obesity and to identify associated factors. Data for 50,095 participants aged 20-39 from Community Health Survey 2019. Chi-square test and multiple logistic regression were used for the analysis. Prevalence for young adults obesity, morbid obesity and severe obesity were 23.60%, 5.86% and 1.31%. Aged of 20's, male, low income, low educational level and marital status were found to be associated with all stages of obesity. Current smoking, high risk drinking, physical activity, health promotion practices, subjective health, EQ-5D, stress, depressive symptoms and comorbidities increased the prevalence of obesity in young adults. Health check-up, subjective health, EQ-5D, stress, depressive symptoms and comorbidities increased the prevalence of severe obesity in young adults. Based on the results, it is necessary to develop and provide focused intervention consisting of characteristics of young adults and stages of obesity.

Purpose: This study was to evaluate the effects of a blended-learning based bioethics program on perceived ethical confidence, critical thinking disposition, moral sensitivity, and academic self-efficacy of the nursing students living in S city. Methods: The program was conducted 13 sessions (2 hours/session) and evaluated for perceived ethical confidence, critical thinking disposition, moral sensitivity, and academic self-efficacy. The collected data were analyzed with descriptive statistics and paired t-test using the SAS 9.4 program. Results: The blended learning based bioethic program was found to be effective for perceived ethical confidence (t=8.70, p<.001), critical thinking disposition(t=8.96, p<.001), moral sensitivity (t=6.43, p<.001), academic self-efficacy (t=20.5, p<.001), and program satisfaction(t=4.92, p<.001). Conclusion: The results of this study suggest that a blended learning program including TBL has advantages of case-based discussion and active interaction for nursing students' bioethics education.

The production of English word-level prominence by Korean learners of English

이고운 한국음운론학회 2022 음성·음운·형태론 연구 Vol.28 No.3

Prominence refers to the relative emphasis that may be given to a syllable in a word (word-level prominence) or to one or more words in a phrase (phrase-level prominence). Korean has been claimed to have phrase-level prominence (Jun, 1996), but not word-level prominence (Lee and Jongman, 2019). Based on this claim, this study aims to investigate whether the same speakers from Lee and Jongman (2019) produce English stress pairs, and if they can, whether their production of word-level stress is expressed in a way similar to native speakers of English. Tokens produced by Korean L2 learners of English and native speakers of English were acoustically analyzed in terms of their duration, intensity, and F0 of the first and second syllables. The results indicate that Korean learners were able to use all three suprasegmental cues to indicate lexical stress in English, but were not able to acquire a new cue (i.e. vowel reduction) in expressing word-level prominence in L2. These results indicate that L2 learners are not able to acquire a new cue that does not exist as an L1 phonological category, but the L1 phonological feature will facilitate the perceptual system of the L2 learners and help them acquire L2 phonetic features.

Perceptual weighting on English lexical stress by Korean learners of English

이고운 한국음성학회 2022 말소리와 음성과학 Vol.14 No.4

This study examined which acoustic cue(s) that Korean learners of English give weight to in perceiving English lexical stress. We manipulated segmental and suprasegmental cues in 5 steps in the first and second syllables of an English stress minimal pair “object”. A total of 27 subjects (14 native speakers of English and 13 Korean L2 learners) participated in the English stress judgment task. The results revealed that native Korean listeners used the F0 and intensity cues in identifying English stress and weighted vowel quality most strongly, as native English listeners did. These results indicate that Korean learners’ experience with these cues in L1 prosody can help them attend to these cues in their L2 perception. However, L2 learners’ perceptual attention is not entirely predicted by their linguistic experience with specific acoustic cues in their native language.
