English Causative Alternation and Its Acquisition
Incheol Choi 현대문법학회 2011 현대문법연구 Vol.64 No.-
Incheol Choi. 2011. English Causative Alternation and its acquisition by Korean learners. Studies in Modern Grammar 64, 183-210. This paper, building on the result of the corpus study in Choi (2010), reveals that Koran learners rarely overgeneralize the English causative alternation rule and it is mainly due to the lexical conservatism in the sense of Baker (1979). In addition, this paper suggests that Korean learners' acquisition process of the phenomenon is influenced by markedness relation coming from the universal semantic properties and Korean verbal morphological system. To support these conclusions, a grammaticality judgement test and a two-alternative forced choice test were carried out.
Why No Backward-moving Wave Occurs in a Homogeneous Semi-infinite Dielectric Slab?
Incheol SHIN,윤성현 한국물리학회 2014 새물리 Vol.64 No.10
The usual textbook determination of the wave resulting from a wave incident onto a homogenous semi-infinite slab presupposes the absence of a backward-moving wave within the slab. However, in the case of electromagnetic waves, this seems, at least to some, to be in apparent contradiction with the physical intuition on the radiation emitted by the constituents of the medium. In this paper we resolve the issue from a scattering-theoretic point of view. For the case of a slab of finite length, the scattered wave within the medium consists of both forward- and backward-moving ones, and the backward-moving part turns out to be a superposition of the waves due to single and multiple planar reflections at the second boundary of the slab. For time-harmonic waves, each such contribution is oscillatory and exponential in the slab length, leading to the absence in dispute. We also provide another justification for the absence based on the simple symmetry of a semi-infinite slab and a composition rule of scattering matrices for one-dimensional composite systems.
English Agreement Revisited: A Constraint-Based Approach without Syncretism
Incheol Choi 현대문법학회 2021 현대문법연구 Vol.111 No.-
Although agreement has been treated as a rudimentary phenomenon in English syntax, this paper raises questions on the traditional conventions. Following the HPSG tradition, this paper suggests that subject-verb agreement involves referential indices whereas the determiner-noun concord involves a morpho-syntactic number feature. However, in this paper, the feature is treated as a medium between morphological signal and semantic interpretation. In addition, it shows evidence that words without overt morphological indication are exempt from the agreement requirement pace the tradition, syncretism. The theoretical basis for the analysis is HPSG-based constructional grammar, and it is shown that its feature structure regime well embraces the suggestion in this paper.
A Novel Abnormal Behavior Detection Framework to Maximize the Availability in Smart Grid
Incheol Shin 한국스마트미디어학회 2017 스마트미디어저널 Vol.6 No.3
A large volume of research has been devoted to the development of security tools for protecting the Smart Grid systems, however the most of them have not taken the Availability, Integrity, Confidentiality (AIC) security triad model, not like CIA triad model in traditional Information Technology (IT) systems, into account the security measures for the electricity control systems. Thus, this study would propose a novel security framework, an abnormal behavior detection system, to maximize the availability of the control systems by considering a unique set of characteristics of the systems.
An Investigation of Korean EFL Learners’ Grammar of English BE: A Corpus-Based Study
Incheol Choi,Daria Soon-Young Seog 현대문법학회 2021 현대문법연구 Vol.112 No.-
The current study investigates the excessive use of BE by young Korean EFL learners for insights into their L2 English grammar construction. The findings reveal that the young Korean EFL learners’ interlanguage grammar of the English BE is not limited to L1 transfer effects but also associated with the developmental processes in the acquisition of the English language. Although be-insertion errors are caused by the conspiracy of various reasons, they trigger the appearance of inflectional category and eventually become the medium for the fully developed inflectional category.
