유아의 운율민감성이 인지-언어적 능력 및 한글 읽기에 미치는 영향
구예리(Yeri Gu),조증열(Jeung-Ryeul Cho),김봉희(Bonghee Kim) 인지발달중재학회 2021 인지발달중재학회지 Vol.12 No.1
연구목적: 본 연구는 만 4, 5세 유아를 대상으로 운율민감성이 단어읽기에 미치는 영향력에 대해서 살펴보 았다. 나아가 유아의 운율민감성과 단어읽기 사이에서 음운인식, 형태소인식 및 철자지식을 포함한 인지-언어적 능력들이 매개적 역할을 하는지에 대해 탐색하고자 하였다. 연구방법: 본 연구의 참여자는 만 4세 유아 50명과 5세 유아 66명(N = 116)을 대상으로 실시하였다. 유아의 단어읽기, 비언어성 지능, 운율민감성(합성명사, 억양, 음장 과제) 및 음운인식(음절인식, 종성 음소인식, 초성 음소인식), 철자지식, 형태소인식을 개인검사를 통해 측정하였다. 연구결과: 위계적 회귀분석 결과, 운율민감성은 나이, 비언어성 지능 및 인지-언어적 요인들(음운인식, 철자 인식, 형태소인식)을 통제한 후에도 단어읽기를 유의미하게 설명하는 것으로 나타났다. 특히 운율민감성 중에서 억양 민감성은 단어읽기를 고유하게 설명하였다. 운율민감성과 단어읽기 간의 관계에서 음운인식을 포함한 인지-언어적 변인들이 매개하는지를 알아보기 위해 중다매개분석을 실시한 결과, 운율민감성은 직접적인 경로를 통해 단어읽기에 유의미한 영향을 미치지 않았으나 음절인식과 종성 음소인식의 간접적인 경로를 통해 단어읽기에 유의미한 영향을 미치는 것으로 나타났다. 결론: 본 연구는 운율민감성이 음운인식과는 독립적인 인지 구조임을 시사하며, 단어읽기 사이에서 음절인 식과 종성 음소인식의 음운인식을 완전 매개하여 한글 단어 읽기에 영향을 주는 것을 시사한다. 이 결과는 유아의 문해 발달에 운율민감성의 중요성을 나타내준다. Objectives: This study examined children aged 4 to 5 years old, about the influence of prosodic sensitivity on Hangul word reading. Furthermore, it was intended to explore whether cognitive-linguistic skills including phonological and morphological awareness and orthographic knowledge plays mediating roles between children’s prosodic sensitivity and word reading. Methods: Participants in this study included 50 4-year-old children and 66 5-year-old children (N = 116). Children were tested with tasks on word reading, nonverbal intelligence, prosody sensitivity (compound nouns, intonation and duration tasks) and phonological awareness (syllabic, phoneme onset, and phoneme coda awareness), orthographic knowledge, and morphological awareness. Results: Hierarchy regression results showed that prosodic sensitivity significantly accounted for reading words over and above biological age, nonverbal intelligence, and cognitive-linguistic factors (phonological awareness, orthographic knowledge, morphological awareness). In addition, the intonation sensitivity in prosodic sensitivity uniquely explains word reading. The results of a multiple mediation analysis to determine whether cognitive-linguistic variables, including phonological awareness, orthographic knowledge, and morphological awareness, mediated in the relationship between prosodic sensitivity and word reading showed that prosodic sensitivity did not have a significant effect on word reading through a direct path, but through indirect paths of syllable and phoneme coda awareness. Conclusions: This study suggests that prosodic sensitivity in Korean children is a cognitive construct independent of phonological awareness, and that phonological awareness mediates between prosodic sensitivity and word reading. These results indicate the importance of prosody sensitivity in literacy development among Korean children.

<P>For biomedical implanted devices, a wireless power or a signal transmission is essential to protect an infection and to enhance durability. In this study, we present a magnetic induction technique for a power transmission without any wire connection between transmitter (Tx) and receiver (Rx) in a micro scale. Due to a micro size effect of a flat spiral coil, a magnetic inductance is not high. To enhance the magnetic inductance, a three dimensional magnetic core is added to an antenna structure, which is consisted of ZnO nano wires coated by a nickel (Ni) layer. ZnO nano wires easily supply a large effective surface area with a vertical structural effect to the magnetic core structure, which induces a higher magnetic inductance with a ferro-magnetic material Ni. The magnetic induction antenna with the magnetic core shows a high inductance value, a low reflection power and a strong power transmission. The power transmission efficiencies are tested under the air and the water medium are almost the same values, so that the magnetic induction technique is quite proper to body implanted systems.</P>

Argument-related recurrent sequences: A corpus-based study targeting L2 learners of English
( Shin¸ Yu Kyoung ),( Gu¸ Yeri ),( Park¸ Yerin ),( Seo¸ Dongju ) 한국중등영어교육학회 2021 중등영어교육 Vol.14 No.4
Legal sentencing involves a multilayered series of arguments leading to a final verdict, just as argumentative essays, a frequent task genre in language classes, should include multilayered argumentation leading to the writer’s conclusions. This similarity suggests that authentic legal sentencing discourse could potentially be useful for language pedagogy. Yet this specific written genre has not attracted much attention in EFL contexts. This study examines three corpora of legal sentencing data (i.e., verdicts of guilty, innocent, and partially innocent when the charges involve more than one crime), amounting to 650,000 words. The study identifies lexical bundles in each corpus and their semantic preferences (i.e., co-occurring words of the sequences in context) in concordance lines. The findings illuminate features of the sentencing genre and suggest its potential as a pedagogical tool for teaching argumentative prose to L2 English learners at the secondary and tertiary levels.
