韓国人日本語学習者の接触場面における発話交替時と発話途中のあいづち的反応の機能と表現形式
李舜炯(LEE, Soonhyeong) 동아시아일본학회 2018 일본문화연구 Vol.0 No.66
본고에서는 자연 담화에서 한국인 일본어학습자가 일본어 모어화자의 발화에 대해 대화상대의 발화 도중 및 발화 교체시에 사용하는 맞장구 반응의 사용 기능과 표현형식에 주목하여 분석, 비교 고찰 하였다. 먼저, 발화 교체시에는 학습자의 맞장구 반응의 사용 기능은 『동의』『이해』『경청』『감정표출』『부정』의 순으로, 발화도중에서는 『경청』『이해』『동의』『감정표출』『부정』순으로 많이 나타났다. 대부분의 경우 모어화자와 학습자는 유사한 사용경향을 보이지만, 모어화자의 경우 발화 교체시에 맞장구적 반응의 표현형식의 종류가 많고 다양하다는 점에서 그 차이점을 확인할 수 있었다. 표현형식으로는 발화 교체시에 『うん系』는 『경청』기능, 『あ系』는 『이해』, 『そうですね』『そうです』는 『동의』, 『いや系』는 『부정』, 『へ-系』는 『감정』 기능으로, 발화도중에는 『はい系는 『경청』, 『あ系』는 『이해』, 『へー系』는 『감정』기능을 주로 나타내면서 화자의 발화가 계속되도록 지지하는 점에서는 한국인 일본어학습자와 일본어 모어화자와 공통된 경향을 보였다. 이러한 결과를 통해 맞장구적 반응이 일본어학습자나 모어화자가 담화전개를 촉진시키기 위한 기술로서 활용되고 있음을 분명히 했다. In this study, I intended to analyze the functions of Aizuchi and representation forms that Korean learners of Japanese use within utterances. First, I could find that Korean learners of Japanese used, between utterances, the function of Aizuchi to express ‘agreement’, ‘understanding’, ‘attentive listening’, ‘emotional expression’, and ‘opposition’ in the order. In addition, they used the representation forms such as ‘unn’ to express ‘attentive listening’, ‘a’ for ‘understanding’, ‘so:desune’ and ‘so:desu’ for ‘agreement’, ‘iya’ for ‘opposition’, ‘he-’ to show ‘emotion’. There was one in common between Korean and Japanese speakers that one speaker actively proceeded discourse by preempting the right to utterance before the other and promoting it. Second, I also confirmed that Korean learners of Japanese used within utterances the functions of Aizuchi to express ‘attentive listening’, ‘understanding’, ‘agreement’, ‘emotional expression’, and ‘opposition’ in the order. They used such representation forms as ‘hai’ to show ‘attentive listening’, ‘a’ for ‘understanding’, and ‘he-’ for ‘emotion’. Here, another in common was found between Korean and Japanese speakers in that both used these representation forms to support a speaker to continue utterances.

Single atomic spin sensing of magnetic interactions in a tunnel junction

Single spins are widely regarded as a leading candidate for realizing next-generation quantum devices for sensing and quantum information processing. Detection and coherent control of single spins require to localize single spins and characterize its magnetic surroundings. Scanning tunneling microscopy in combination with electron spin resonance (ESR-STM) technique [1] enables a direct access to the quantum states of single magnetic atoms or molecules on surfaces. Using ESR-STM, we investigated spin resonance of hydrogenated Ti (TiH) atoms adsorbed on bridge binding site of MgO in a two-dimensional vector magnetic field. Here, the spin 1/2 TiH atom with no magnetic anisotropy was employed as a probe of magnetic environments at the tunnel junction. We found both ESR frequency and amplitude change as a function of the angle of vector magnetic fields. The resonance frequency varied by different vector magnetic fields indicates an anisotropy of the g-factor, resulting from the variation of angular momentum contributions due to the crystal fields. We developed a stereoscopic way to unravel the g-factor along the three principal axes. Moreover, ESR amplitude dependence on the direction of magnetic fields provides the further understanding of ESR mechanisms, which results from two factors, tunneling magnetoresistance (TMR) effect at the spin-polarized STM junction and the transverse magnetic field to drive ESR. Our results will enable to predict ESR active spin centers on different substrates as well as in other quantum-nanoscience platforms.
