ECM and Scrambling at the Edges of CP in Korean

YongSuk Yoo 한국생성문법학회 2021 생성문법연구 Vol.31 No.2

This paper investigates various extraction patterns out of phases with multiple edges in Korean, and provides additional evidence for Bošković’s (2016) proposal that the edge status of an element has to be determined contextually. The case studies I conduct concern Exceptional Case Marking and Scrambling from the embedded CP in Korean. The aim of this paper is to show that the various word order patterns that are created by interactions of these operations can be accounted for in a uniform manner once the contextuality of phasal edges is taken into consideration.

The Semantics of before and after in Korean

( Yoo Yongsuk ) 한국현대언어학회 2019 언어연구 Vol.35 No.2

The main goal of this paper is to provide a formal account of Korean before and after clauses with special attention paid to their morphological selection. Being apart from temporal morphology, the current analysis of Korean before and after clauses can shed new light on the discussions of selectional requirements of before and after clauses. In particular, I will show that before and after in Korean exhibit the schism based on the presence of Earliest operator of the type < i,t >,t> only in after clauses. The current paper also presents various language-specific tests, including the distribution of mod-insertion rule (cf. Kitagawa and Ross 1982, An 2014 among others). It will be shown that the complement of {Earliest, After} has to be relativized to provide a correct syntactic/semantic composition in after clauses. In contrast to Korean after, Korean before does not involve such pronominal element; therefore, it does not require the relativization of the embedded clause. (Korea Naval Academy)

On the Edges of Korean NP

( YongSuk Yoo ) 대한언어학회 2021 언어학 Vol.29 No.3

This paper shows that a particular pattern in Korean Possessor Raising constructions can be accounted for if only the highest specifier of NP counts as a phasal edge. This paper contributes to the ongoing debate of the contextuality of phasal edgehood: The status of a Spec/adjunct regarding the phasal edge can be affected by the syntactic context in which the Spec/adjunct appears. In particular, only the highest specifier of NP counts as a phasal edge and the lower specifier of NP is only accessible when the highest one undergoes movement. This article also discusses issues regarding the syntax and semantics of adjectives and possessors in Korean nominal phrases, arguing that adjectives and possessors in Korean are NP-adjuncts and there is no functional projection such as DP. This also sheds a new light on the discussion of Korean possessor raising constructions.

The Cartography of RCs in Korean & Japanese

YongSuk Yoo,Myung-Kwan Park 서울대학교 언어교육원 2018 語學硏究 Vol.54 No.3

This paper shows that the difference in the structure of relative clauses (RCs) in Korean and Japanese determines the availability of say-omission/contraction in these two languages. Specifically, in addition to providing a novel observation about say-omission/contraction in Korean and Japanese, we argue that this phenomenon is attributed to the presence of a CP layer in RCs in Korean (Yoon 1990, Han 1992 among many others), but to the lack thereof in Japanese (Saito 1985; Murasugi 1991; Taguchi 2008; Miyagawa 2011; among many others). We argue that RC-internal say-omission/contraction in Korean is an instance of TP-ellipsis. We adopt the theory of ellipsis in Bošković (2014), where deletion can target phases or the complements of phasal heads. Thus, the subject, the object, and the complement clause of say within the RCs of Korean are moved out of and survive an elison of TP (i.e., the complement of the phasal head C) because of the presence of the CP-domain providing a landing site, whereas in Japanese such an option is not available.

투자자의 관심수준과 경영자의 자발적 이익예측정보 공시 간의 관계

윤용석 ( Yongsuk Yun ),유승원 ( Seung-weon Yoo ) 한국회계학회 2017 회계학연구 Vol.42 No.4

본 연구는 투자자의 관심수준(investor attention)과 경영자의 자발적 공시의사결정 간의 관계에 대하여 분석한다. 구체적으로 Da et al.(2011)이 투자자의 관심수준을 측정하는 직접적인 대용치로 제시한 검색량 지수(search volume index)를 사용하여 기업에 대한 투자자의 관심수준이 높고 낮음에 따라 경영자의 자발적 공시의사결정에 변화가 있는지를 분석한다. 아울러 제공되는 예측정보의 질적 속성에 따라 투자자 관심수준과 경영자 예측정보 공시 간의 관계가 차별적으로 나타나는지를 분석한다. 2007년부터 2013년까지의 유가증권 상장법인을 대상으로 분석을 시행한 결과는 다음과 같다. 첫째, 당기 투자자 관심수준이 높을수록 경영자의 자발적인 이익예측공시 가능성이 유의하게 높은 것으로 나타났다. 이러한 결과는 다음의 두 가지 원인에 의해 설명될 수 있다. 먼저 투자자 관심 수준이 정보에 대한 수요를 나타낸다면, 경영자는 이러한 투자자의 정보수요를 충족시켜주기 위하여 자발적으로 이익예측정보를 제공하는 것으로 해석할 수 있다. 또는 투자자 관심수준이 높은 경우 정보에 대한 반응이 클 것으로 기대되고 이에 따른 유동성 증가 등의 효익이 증가할 것으로 기대하여 경영자가 이익예측정보를 제공하는 것으로도 해석할 수 있다. 둘째, 당기 투자자 관심과 경영자의 예측정보 공시 간에 나타나는 양(+)의 관계는 이익예측치의 편의의 성격에 상관없이 동일하게 나타났다. 구체적으로, 낙관적인 편의가 있는 경우와 비관적인 편의가 있는 경우 모두 투자자 관심수준이 높을수록 공시 가능성이 유의하게 높은 것으로 나타났다. 이는 앞의 결과와 관련된 경영자의 공시 원인 중 투자자의 정보수요를 충족시켜주기 위해 자발적인 이익예측이 결정됨을 지지하는 결과로 해석된다. 마지막으로 경영자 이익예측정보 공시 전·후 기간에 대한 투자자 관심수준을 분석한 결과, 경영자 이익예측정보가 공시되기 전 기간과 공시가 이루어진 기간의 투자자 관심수준은 높은 것으로 나타났으나 정보가 공시된 이후 기간에 대한 투자자 관심수준은 낮은 것으로 나타났다. 이는 기업에 대한 정보를 얻고자 하는 투자자들의 정보수요로 인한 높은 관심수준이 경영자의 공시의사결정을 통해 충족되어 이후 관심수준이 낮아짐을 보여주는 것으로써, 경영자의 자발적 이익예측공시가 정보제공유인에 기반함을 시사하는 두 번째 가설에 대한 결과를 뒷받침한다. 본 연구는 투자자의 관심수준이 경영자의 자발적인 이익예측공시 의사결정에 영향을 미친다는 증거를 제시함으로써, 경영자의 공시의사결정에 있어서 시장특성적인 측면에서의 결정요인을 제시하는 선행연구들과 맥락을 이루는 동시에 경영자의 자발적인 이익예측공시의 결정요인으로서 주식시장 투자자의 관심이라는 새로운 측면을 제시하고 있다. This paper investigates how investor attention affects the manager`s voluntary disclosure decisions. Proxying for investor attention using the search volume index suggested by Da et al.(2011), we examine whether managers react strategically to investor attention via increasing or decreasing the frequency of management earnings forecasts. In addition, we investigate whether the association between investor attention and the frequency of management earnings forecasts is changed when considering bias of management earnings forecasts. Using a sample consisted of listed companies during the period of 2007 to 2013, we find the following results. First, when investor attention is higher, managers` voluntary earnings forecasts are significantly more disclosed. Second, the association between investor attention and the frequency of management earnings forecasts is unchanged even when considering bias of management earnings forecasts. More specifically, the frequency of optimistic and pessimistic management earnings forecasts are more disclosed when the level of investor attention is high. Finally, we examine the change of investor attention during before and after management earnings forecasts periods. The results show that the level of investor attention is high during the periods before management earnings forecasts disclosed, while, the level of investor attention is low during the periods after management earnings forecasts disclosed. These results suggest that high level of information demand of investors before voluntary disclosure goes down after getting information via management earnings forecasts, therefore supporting information views.

Mun Yongsuk,박준민,김훈,김현종,김정언,김아정,Lee Yoo Bin,전우찬,Kwak Hye Weon 대한응급의학회 2022 Clinical and Experimental Emergency Medicine Vol.9 No.3

Objective Since onsite education is difficult due to the COVID-19 pandemic, official development assistance (ODA) projects have implemented online training of trainers (ToT) for emergency medical experts and staff. This study aims to share and discuss the ToT experience and its results in Uzbekistan. Methods We trained emergency medical advanced course instructors through online ToT among emergency medical service experts in Uzbekistan as a part of an ODA project. After the ToT, instructors were selected based on written tests, video monitoring of practice, and simulation performance. They operated the emergency medical course including lectures, practices, and simulations for 5 days. We tested the trainees through written tests before and after the course. They were surveyed regarding the course contents, its relevance, and their satisfaction with the course. Results Six instructors were selected after the online ToT program. They educated 68 emergency medical workers through the three training courses. The total score of the pretest was 129.2±34.8, and the posttest score was 170.8±31.2, which was significantly higher (P<0.05). The satisfaction calculated by adding the values of survey items for this curriculum was 28.0 (interquartile range, 26.0–30.0), and there was no statistical difference regarding trainee satisfaction between the three courses (P=0.148). Conclusion Instructors trained by online ToT programs could provide an in-person emergency medical advanced course.

Comparing Numeral Classifier Constructions in Japanese and Korean: The Role of Case Projection in Constituency Differences

( Youngyoon Cho ),( Yongsuk Yoo ) 대한언어학회 2023 언어학 Vol.31 No.2

This paper provides a comparative analysis of numeral classifier constructions in Japanese and Korean, focusing on the differences in constituency and the underlying syntactic structures. Through the examination of the base structures of NPs combined with conjunction and their total and separate interpretations, as proposed by Sudo (2015), we apply various constituency tests to investigate these phenomena. Our findings reveal key differences between the two languages, particularly in the role of Case Projection in determining constituency properties. This study contributes to the understanding of Japanese and Korean numeral classifier constructions and the broader field of comparative linguistics.

Scrambling in Korean Meets the Labeling Theory

( Park Myung-kwan ),( Yoo Yongsuk ) 서강대학교 언어정보연구소 2019 언어와 정보 사회 Vol.37 No.-

This paper investigates the nature of scrambling in Korean, which is a word order permuting operation in syntax. We re-characterize it in light of Chomsky’s(2013, 2005) recent theory of labeling. We are in keeping with the thesis that scrambling in Korean undergoes non-A, non-operator movement and adjoins to its target (Saito 1985 and thereafter). We show that because of the lack of obligatory agreement, there is no A vs. A’-distinction in this language, so that in overt syntax a scrambled expression enters into licensing relation just like an adjunct. Therefore, it cannot be deployed into the properly labeled structure in this level of syntactic component. To overcome the problem with labeling, it generally undergoes radical reconstruction to its underlying position, but it also markedly enters into semantic predication at the interface.
