Derivation of [XP-NUN?] Revisited: Reply to Park (2021)

정대호 현대문법학회 2022 현대문법연구 Vol.115 No.-

Contra Chung’s (2021a) contrastive topic (CT) movement analysis of the so-called contrastive topic fragment (CTF) of the form [XP-NUN?], Park (2021) claims the following: (i) The pre-NUN remnant can be a contrastive focus (CF) (as well as a CT); (ii) the CTF is derived from a cleft-like wh-construction with ettehkey ‘how’ in the pivot; and (iii) the remnants undergo scrambling. This paper makes the following three points: (i) given the generally accepted definitions of topic, the pre-NUN element behaves like a CT, as suggested in Chung (2021a); (ii) Park’s cleft-like construction based derivation faces non-trivial problems, especially with respect to the available interpretation of the CTF; and (iii) Park’s generalized question [XP-NUN etteh/ettehkey ‘how’ ...?] can in fact be viewed as a derived structure due to a clausal replacement by etteh/ettehkey, analogous to the kuleh/kulehkey replacement entertained in Park (2013) and Sohn (2019).

MPIE를 이용한 임의의 형상을 갖는 마이크로스트립 패치 안테나의 해석

정대호,김태원,김정기 한국통신학회 1993 韓國通信學會論文誌 Vol.18 No.8

임의 모양을 갖는 마이크로스트립 안테나의 해석에 역점을 두었다. 마이크로스트립 안테나의 가장 일반적이고 정확한 해석법은 주파수 영역에서 정의되는 전계적분방정식을 이용하는 것이다. 본 논문에서는 전계적분방정식을 수정한 MPIE(Mixed potential integral equation)를 이용하여 공간영역에서 해를 구하였다. 이 방법은 스칼라와 벡터 포텐셜과 관련된 Green함수를 다층매질 이론에 의해 계산하고 Sommerfeld 적분방정식에 의해 표현한다. 또한 적분방정식은 rooftop 부분기저함수를 이용한 모멘트법을 이용하여 해를 구하였다. 따라서 임의의 모양의 마이로스트립 안테나를 임의의 주파수와 임의의 기판상에서 해석할 수 있다. 구형 마이크로스트립 안테나와 L자형 마이크로스트립 안테나의 수치 결과를 실험치와 비 교하였다. We will put the emphasis on the analysis of arbitrarily shaped microstrip antennas. The most general and rigorous treatment of microstrip antennas is given by the electric field integral equation(EFIE), usally formulated in the spectral domain. In this paper, we use a modification of EFIE, called the mixed potential integral equation(MPIE) , and we solve it in the space domain. This technique uses Green's functions associated with the scalar and vector potential which are calculated by using stratified media theory and are expressed as Sommerfeld integrals. The integral equation is solved by a moment's method using rooftop subsectional basis function. Thus, microstrip patches of any shape can be analysed at any frequency and for any substrate. Numerical results for a rectangular patch and for a L-shaped patch are given and compared with measured values.

Some Remarks on Ahn and Cho’s (2006) Dual Analysis of Korean RNR

정대호 경희대학교 언어정보연구소 2008 언어연구 Vol.25 No.3

There have been various approaches entertained in the literature to account for the properties that the so-called right node raising construction (RNR) displays: Across-the-board rightward movement analyses, PF deletion analyses, and multi-dominance analyses, to name a few. Pointing out that no single uniform analysis can account for all the properties displayed by the RNR, Ahn and Cho (2006) propose a heterogeneous analysis approach: There are two types of RNR structures, one being derived by a semantically constrained ellipsis (S-ellipsis), while the other being derived by a phonologically constrained ellipsis (P-ellipsis). This article shows that despite some genius in it, Ahn and Cho’s (2006) dual analysis approach faces some empirical and theoretical problems. It will be first shown that there exist some RNR properties which are hardly accounted for by any version of ellipsis approach, including S-ellipsis or P-ellipsis. It will be also shown that the mechanism of P-ellipsis, if strictly followed, leads to some non-trivial technical and semantic problems. The conclusion drawn is agnostic: The RNR is still in a haze.

Is amwu( N)-to a negative quantifier?

정대호 경희대학교 언어정보연구소 2012 언어연구 Vol.29 No.3

Watanabe (2004) analyzes the traditionally called negative polarity item in Japanese as a negative quantifier (N-word), to account for the fact that it can be a fragmental answer to an affirmative interrogative sentence, despite the apparent polarity mismatch between the affirmative predicate in the antecedent clause and the negative predicate in the ellipsis site. The polarity disparity resolves in his system due to Agree between the N-word and the elided negative predicate, which induces the [NEG] feature of the former to get copied into the latter and ultimately cancels out the [NEG] feature of the predicate in the ellipsis site as an instance of double negation. This work argues that although Korean behaves like Japanese with respect to the N-word fragments, the negative quantifier analysis cannot be carried over to Korean based on the following two reasons: (i) the neg-feature-copy-followed-by- cancel-out mechanism leads to interpretation failure in some structures involving an N-word (e.g., an N-word as a short answer to a negative interrogative, an N-word in the RNR construction, and an N-word in the non-negation context); and (ii) polarity mismatch can be induced by a non-N-word (e.g. acik ‘still, yet’ as a short answer to an affirmative interrogative sentence and selma ‘(not) a chance’ as a short response to an affirmative declarative sentence). As for the availability of an N-word as a fragmental response to an affirmative sentence, it is speculated in this work, conforming to Ahn and Cho (2011), that such N-word fragments involve no ellipsis and they are to be pragmatically licensed. If this is on the right track, then the semantic isomorphic condition becomes irrelevant to such fragments, and the polarity mismatch problem disappears accordingly.

Effect of Stabilization Annealing on SCC Susceptibility of β-Annealed Ti-6Al-4V Alloy in 0.6 M NaCl Solution

정대호,박지호,안수진,성효경,권용남,김상식 대한금속·재료학회 2018 METALS AND MATERIALS International Vol.24 No.1

The effect of stabilization annealing on the stress corrosion cracking (SCC) susceptibility of β-annealed Ti-6Al-4V(Ti64) alloy was examined in an aqueous 0.6 M NaCl solution under various applied potentials of +0.1, -0.05 and -0.1 V vs Ecorr, respectively, at a strain rate of 10-6s-1. The stabilization annealing substantially improved the resistanceto SCC of β-annealed Ti64 alloy in 0.6 M NaCl solution under cathodic applied potentials, while the effectwas marginal under an anodic applied potential. It was also noted that the areal fraction between ductile and brittlefracture of β-annealed Ti64 specimens, which were slow strain rate tested in 0.6 M NaCl solution, varied with stabilizationannealing and applied potentials. The effect of stabilization annealing on the SCC behavior of β-annealed Ti64 alloy in SCC-causing environment was discussed based on the micrographic and fractographicobservation.

How Korean and Chinese Differ in the Licensing of Indeterminates

정대호,박명관 서강대학교 언어정보연구소 2020 언어와 정보 사회 Vol.40 No.-

In this paper we investigate epistemic adverbs (E-adv’s) that induce intervention effects (IEs) for indeterminates of interrogative use in Korean and Chinese. We argue that the Korean E-adv’s undergo feature movement, being subject to the IEs when the E-adv’s intervene. On the other hand, the Chinese E-adv’s undergo overt phrasal movement, obviating the IEs. Meanwhile, Chinese indeterminates of non-interrogative use are licensed by negation or E-adv’s in non-veridical contexts to function as an existential quantifier. Korean counterparts are locally licensed by the particle –inka on them.
