Focus and Particle Constructions
이원빈 한국영어학회 2004 영어학 Vol.4 No.2
This paper concerns the issue related to the focus phenomena with a particular reference to the two alternating orders (continuous vs. discontinuous orders) in particle constructions in English. To explain the alternation of word order in particle constructions, I will argue that the choice of word order is closely related to the focus property of the object DPs. Following Drubig (2003), I will assume that focus-feature is taken to be a syntactic feature assigned freely to a lexical head in the process of the mapping into Lexical Array (LA) from the lexicon (LEX). I argue that the focus-marked object DP cannot move out of its focus domain and thus the continuous order is derived. In the case of non-focus-marked object DP, however, the object DP moves out of VP in order to receive an appropriate interpretation. As a result, the discontinuous order is derived.
On Short Argument Scrambling: A contrastive focus movement approach
이원빈,조성은 사단법인 한국언어학회 2004 언어학 Vol.0 No.38
The aim of this paper is to explore the motivation for the short argument scrambling and its general properties (its A- and A'-property of scrambling). Regarding the former, we propose that scrambling consists of a two-step process: object shift (A-movement) and contrastive-focus driven movement (A'-movement). Regarding the latter, we resolve the puzzle related to both binding and the mitigation of WCO effects, assuming that scrambling has only A'-movement property against the traditional assumption that short scrambling has properties of both A- and A'-movement. We also show that the A-movement properties of short argument scrambling result from the operation object shift.

The practical design methodology of a three-phase dual active bridge (3ph-DAB) converter applied to low voltage direct current (LVDC) applications is proposed by using a mathematical model based on the steady-state operation. An analysis of the small-signal model (SSM) is important for the design of a proper controller to improve the stability and dynamics of the converter. The proposed lead-lag controller for the 3ph-DAB converter is designed with a simplified SSM analysis including an equivalent series resistor (ESR) for the output capacitor. The proposed controller can compensate the effects of the ESR zero of the output capacitor in the control-to-output voltage transfer function that can cause high-frequency noises. In addition, the performance of the power converter can be improved by using a controller designed by a SSM analysis without additional cost. The accuracy of the simplified SSM including the ESR zero of the output capacitor is verified by simulation software (PSIM). The design methodology of the 3ph-DAB converter and the performance of the proposed controller are verified by experimental results obtained with a 5-kW prototype 3ph-DAB converter.
