Lexical Bundles in the Spoken Discourse of Native and Nonnative Speakers of English
우수정 한국언어연구학회 2019 언어학연구 Vol.24 No.3
The present study explores the lexical bundles in the spoken discourse of native and Korean learners of English to examine how they are similar and different in structural and functional distribution. The results show that only a few lexical bundles are in common between the two groups, and the frequency distribution of the common bundles is significantly different. Moreover, it is found that there are three major characteristics in the use of lexical bundles in the Korean learners’ spoken discourse. First of all, the Korean learners tend to overuse certain bundles such as I think it is, I agree with the, and bundles with particular connectors such as and, and so. Second, they rely heavily on a small set of lexical bundles which indicates that they possess limited repertoire of lexical bundles. Lastly, the Korean learners’ lexical bundles are more formal than those in the native speakers’ spoken discourse. It is attributed to exposure of formal expressions through textbooks rather than colloquial expressions. The results of the present study also support the idea that the lexical bundles should be underlined in the second and foreign language education.

Electromagnetic wave absorbing materials have been developed to reduce electromagnetic interference (EMI) for electronic devices in recent years. In this study, Fe-Si-B-Nb-Cu base amorphous strip was pulverized using a jet mill and an attritor and heat-treated to get flake-shaped nanocrystalline powders, and then the powders were mixed, cast and dried with dielectric $Al_{2}O_{3}$ powders and binders. As a result, the addition of $Al_{2}O_{3}$ powders improved the absorbing properties of the sheets noticeably compared with those of the sheets without dielectric materials. The sheet mixed with 2 wt% $Al_{2}O_{3}$ powder showed the best electromagnetic wave absorption, which was caused by the increase of the permittivity and the electric resistance due to the dielectric materials finely dispersed on the Fe-based powder.
부모의 온정적 양육행동과 또래 상호작용이 유아의 외현화 문제행동에 미치는 영향

The purpose of this study was to examine the effects of parenting behavior and peer interaction on externalizing problem behaviors of preschoolers. The data of 953 49~55 month old preschoolers and their parents were extracted from the Korean Children Panel Survey of Child-Care Policy Research Institute(2012). This study was conducted with Structural Equation Modeling(SEM). The results of this study were as follows. First, parenting behavior had a direct influence on externalizing problem behaviors of preschoolers. Second, parenting behavior had a direct influence on preschoolers' peer interaction. Third, preschoolers' peer interaction had a direct influence on externalizing problem behaviors of preschoolers. Fourth, preschoolers' peer interaction had mediating effects on the relationship between parenting behavior and externalizing problem behaviors of preschoolers
Error Correction in Pedagogical Context
우수정 한국언어연구학회 2012 언어학연구 Vol.17 No.1
The activity of correction is prevalent and important in the context of language teaching and learning since the correction is closely related to the work of teaching. This paper explores correction sequences in a pedagogical context to examine how the teachers design their correction relevant turns. In the activity of correction, two distinct actions are involved: locating an error and replacing the error with what is correct. Using conversation analytic framework, it is observed that the teachers in the study use linguistic resources when locating errors, and this task can be accomplished successfully when the interlocutors work together and build common understanding on what the "matter-of-focus" (Brouwer, 2004) is in ongoing conversation. In doing to correcting, the teachers use several strategies to make the correction less-face-threatening and less salient so that the other purpose of the talk, teaching, can be focused.
Functions of And in EFL Learners' Spoken Discourse
우수정 한국언어연구학회 2015 언어학연구 Vol.20 No.3
This paper examines a coordinate conjunction and in EFL learners' unplanned spoken discourse to look at how the learners use and in the spoken discourse. According to Biber et al., (1999), and is the most common coordinator in all the register. And it has been argued that and has multifunctions (Schiffrin, 1986; Celce-Murcia & Larsen-Freeman, 1999). And found in the EFL learners spoken discourse of the present study is also multifunctional. First of all, and is used to link between clauses to simply add a text to another in a discourse. Secondly, and is used to mark ‘internal sequence’ (Halliday & Hasan, 1976) in that it indicates ‘next in a series (of things to be said). In other words, it denotes the next thing I want to say (know) is. Third, and is used as a boundary marker in that it signposts the beginning and the ending of a new (or sub-) topic. Lastly, and occurs with hesitation markers frequently indicating the speaker has more to say but cannot come up with what to say next immediately.
