Resolution of PP attachment ambiguities by Korean learners of English: Effects of linear distance and proficiency

Soondo Baek 한국영어학학회 2014 영어학연구 Vol.20 No.3

Baek, Soondo. 2014. Resolution of PP attachment ambiguities by Korean learners of English: Effects of linear distance and proficiency. English Language and Linguistics 20.3, 35-58. This study examined the effect of linear distance and proficiency on L2 online resolution of PP attachment ambiguities in verb–NP–PP sequences, where the PP can be attached to either the verb or the NP. Forty two Korean college students of English contributed reading time data through a self-paced reading task. Test sentences were designed so that the PPs were construed with either the verb or the NP in terms of semantic plausibility (e.g.,The burglar opened the safe with a [large hammer/broken lock].). The length of theNP was also manipulated (e.g., The burglar opened the [safe/enormously big black safe] with a large hammer.). The results showed that VP attachment of the PP wasgenerally preferred over NP attachment and that the strength of the preference was larger for higher than lower proficiency learners. The effect of linear distance was reliable only for higher proficiency learners, who showed a weakened VP attachment preference with the increase of the distance between the verb and the PP. The results suggest that attachment preferences and linear distance effects in L2 PP attachment disambiguation should be understood in relation to the learners’ level of proficiency

The Effects of Loosely Coupled Hand-Off Operations on Bucket Brigade Order Picking Systems

Soondo Hong,Youngjoo Kim 대한산업공학회 2018 Industrial Engineeering & Management Systems Vol.17 No.4

Hand-off delays in bucket brigade order picking systems occur when downstream pickers have to wait to receive totes from upstream pickers. This paper introduces a method, termed a loosely coupled hand-off, to reduce waiting delays, and it conducts analytical and simulation studies to identify insights. The loosely coupled hand-off method, which is popular in industry, is preferred by pickers to reduce the expected hand-off delays of downstream pickers. We express the looseness of the hand-off synchronization, i.e., the threshold of the early release, as real number τ ≥ 0. To overcome the throughput reduction, we generalize the looseness from the perspective of a picker’s decision making and throughput improvement and extend the looseness parameter into a practical hand-off framework with measurements including the relative looseness of the hand-off (δ), the increment of work-in-process (WIP) (ω), and the work range of the loosely coupled hand-off (ψ) allowed. We find that the adjusted loosely coupled hand-off framework to balance the hand-off delay reduction and the throughput gains reduces hand-off delay by 30~88% and improves throughput by 2.7~6.4%. In general, to attain the overall system’s throughput improvement, the gains in the hand-off delay require the WIP level and the range adjustments.

Psychological reality of the trace in L2 English sentence processing by Korean learners

( Soondo Baek ) 한국외국어대학교 언어연구소 2017 언어와 언어학 Vol.0 No.74

This study tested the psychological reality of a syntactic trace in L2 sentence processing by capitalizing on the finding that sentences are read faster when discourse-given information precedes discourse-new information. In a self-paced reading experiment, 32 Korean learners of English read English indirect wh-questions in which one of the two objects of a double object construction was extracted. The unextracted object was either discourse-new or discourse-given (e.g. I wondered which cookie the woman would give the/a dog). The overall results suggest that the unextracted object was more difficult to read when it was given than new. This finding is interpreted as suggesting that information structure was perceived by the participants based on the surface position of the wh-phrases, not on their trace position.

Traps development for environment-friendly management of insect pests

해충의 발생은 생물적 및 비생물적 요인과 밀접하게 관련되어 있다. 하지만 근년의 해충 발생양상은 생물적 요인보다 비생물적 요인에 의해 더욱 큰 영향을 받는 것으로 여겨진다. 즉 지구온난화로 인해 월동하는 해충 개체군의 증가 및 남방계 해충의 서식지의 북상, 산림 및 농업생태계의 변화로 인한 해충 발생의 다양성과 역동성 제고, 교역량 증가로 인한 외래해충의 유입증가 및 정착에 따른 돌발적 대발생 등을 들 수 있다. 그리하여 해충에 의한 농작물의 안전 및 안정생산이 이전보다 크게 위협받게 되었고, 농업현장에서 해충의 효과적 관리를 위한 실용적 기술개발은 더욱 강하게 요구되고 있다. 국내에서 노린재류는 2000년 이후부터 발생량이 크게 증가하여 콩과 및 과수작물 등의 수량과 품질을 크게 떨어뜨리는 주요한 해충으로 인식되어 있다. 두류 및 과수류에 발생하는 노린재의 종류는 다양하지만, 주요 노린재류는 크게 호리허리노린재과(Alydidae)와 노린재과(Pentatomidae)로 구분할 수 있다. 이들 노린재류는 형태적 차이뿐만 아니라 비행성과 이동성 등에서 뚜렷한 행동적 차이를 가지고 있다. 그로인해 톱다리개미허리노린재는 통발트랩과 펀넬트랩으로 잘 포획할 수 있으나, 썩덩나무노린재와 갈색날개노린재는 유인되지 않는다. 그리하여 노린재의 종류에 관계없이 범용으로 노린재류를 잘 포획할 수 있는 트랩개발이 필요하게 되어 로케트트랩(Rocket trap)을 개발하게 되었다. 농업해충 가운데는 양성주광성(Positive phototaxis)을 가져 밤에 불빛으로 모여드는 특성을 가진 해충이 많이 있다. 스마트트랩(Smart trap)은 낮에 태양광을 축전하고 밤에 해충이 선호하는 파장의 램프를 작동시켜 나비목, 딱정벌레목, 매미목 및 노린재목 등의 해충을 친환경적으로 대량 포획할 수 있는 포충기를 개발하였다. 벼 및 밭작물 재배포장, 과수원, 플랜테이션 농장, 휴양림, 전원주택 및 골프장 등에 스마트트랩을 설치하여 주광성 해충을 효과적으로 포획하는데 국내·외에서 사용되고 있다. 또한 약제를 가열하지 않고 나노입자로 분무하여 시설작물, 축사 및 버섯재배사 등에서 문제되는 병해충을 생력적으로 관리할 수 있는 비가열식무인연막기를 개발하여 그 효과를 검정하고 있는 단계이다. 아직도 많이 부족하고 어느 것 하나 제대로 한 것 없는 것 같은데, 2018년 한국응용곤충학회 추계 학술발표회에서 제 1회 응용곤충학상을 받게 된 것은 개인적으로 큰 영광이라 하지 않을 수 없다. 그동안 함께 연구해온 동료와 학술적 동기를 유발시킨 한국응용곤충학회 그리고 트랩개발에 적극 협조해준 산업계 등에 깊은 감사를 드립니다.

Online Processing of English Articles and Information Structure by Korean College Students

Soondo Baek 한국응용언어학회 2014 응용 언어학 Vol.30 No.2

English articles mark the definiteness of co-occurring noun phrases (NPs), which in turn correlates with the information status of the referents described by the NPs (e.g., Clifton & Frazier, 2004). Previous studies show that the information given in the discourse tends to be encoded earlier in an utterance than the information to be newly introduced (e.g., Arnold, Wasow, Losongco, & Ginstrom, 2000). The present study investigates an aspect of the knowledge that adult Korean learners of English have of the English articles by testing their sensitivity to the link between the definiteness of NPs and the NP’s preferred order in a sentence. Twenty-four learners of English read double object (DO) and prepositional object (PO) constructions on a word-by-word basis, in which the two postverbal NPs were contrasted in definiteness by switching the and a (e.g., The pitcher showed the boy a ball, The pitcher showed a boy the ball; The pitcher showed the ball to a boy, The pitcher showed a ball to the boy). The results show that the participants read the definite?indefinite post-verbal NP sequences more rapidly than indefinite?definite sequences in the DO constructions but not in the PO constructions, which indicates their sensitivity to the given-before-new preference in the discourse informational organization as well as to its interaction with syntactic alternation. The findings are discussed in terms of L2 acquisition and instruction of English articles.

Dative Alternation in Korean L2 English Learners’ Essay Writing

Soondo Baek 담화·인지언어학회 2016 담화와 인지 Vol.23 No.1

This study investigates the effects of discourse-related factors on the English dative alternation in Korean L2 learners’ writing by comparing a learner corpus (YELC) and a corresponding native speaker corpus (LOCNESS). Factors of interest are pronominality, definiteness and linear length of the two post-verbal arguments of the dative construction, which have been shown in previous studies to affect the choice between alternative double object and prepositional constructions. The results suggest (i) that Korean learners generally prefer the prepositional construction over the double object construction as compared with native speakers and (ii) that constraints involving pronominality are acquired earlier or more easily than those involving definiteness or length. These findings are discussed in terms of the role of instruction and L1 transfer in L2 acquisition of the English dative construction.

Working Memory as an Independent Predictor of Second Language Sentence Comprehension

Soondo Baek 한국응용언어학회 2013 응용 언어학 Vol.29 No.4

The present study investigates how working memory capacity in a second language (L2) is associated with individual differences in L2 sentence comprehension and assesses whether its predictive power is independent of proficiency in the L2. Working memory capacity was operationalized as reading span, and proficiency as cloze test performance. Thirty-two advanced L1-Korean L2-English learners read sentences on a word by word basis that contained a subject-modifying relative clause (e.g., The banker that irritated the lawyer played tennis every Saturday). Comprehension was checked for each sentence. The participants were also administered a reading span task and a cloze test. The results show that the two individual differences measures both reliably predict learners’ sentence comprehension accuracy independently of each other, suggesting the possibility that working memory capacity and proficiency reflect different components of the ability to interpret L2 sentences. These findings are discussed in terms of the potential implications for better understanding of individual differences in L2 sentence comprehension.
