Underspecification and Defaults in Korean Aspectual Periphrasis

Seungju Yeo 한국생성문법학회 2018 생성문법연구 Vol.28 No.3

Yeo, Seungju. 2018. Underspecification and Defaults in Korean Aspectual Periphrasis. Studies in Generative Grammar, 28-3, 411-432. This paper proposes a morphosyntactic analysis of grammatical aspect, with two functional heads Asp and Telic dedicated for yielding the array of grammatical aspect patterns observed in Korean. This approach is capable of accounting for why iss-headed periphrases diverge from the other compositionally well-behaving periphrases that maintain a one-to-one correspondence between the aspectual exponents and the resulting grammatical aspect. As opposed to “compositional” aspectual auxiliaries, iss- is neutral and realizes Asp bearing [∘ PERFECT ], an underspecified functional head. This underspecified head is responsible for ambivalence of iss-headed periphrases.

교실 단위 작문 평가에서 활용 가능한 작문 자동 채점 프로그램의 설계 방안에 대한 연구 - 인지공학적 설계 접근과 채점자의 인지 부하 요인을 고려하여 -

김승주 ( Kim¸ Seung Ju ) 청람어문교육학회 2021 청람어문교육 Vol.- No.83

그간 국외에서 개발된 글 단위 작문 자동 채점 프로그램은 교실 단위 작문 평가 상황에서 활용이 제한적이라 알려져 있다. 그 이유는 기본적으로 기존 작문 자동 채점 프로그램의 설계 방식에 기인한다. 이에 본 연구에서는 이를 개선하기 위한 대안으로서 인지공학적 설계 방식에 따라 작문 자동 채점 프로그램을 개발할 것을 제안하고자 하였다. 이에 인지공학적 설계 접근에 따라 채점자의 인지 과정, 그리고 채점 과정에서 채점자인지 부하와 관련한 선행 연구를 살펴본 결과 (1)텍스트 이해 과정, (2)텍스트 평가 과정, (3)평가 결과 정교화 과정 등의 채점 세부 과정별 인지 부하 요소를 탐색하였으며, 이를 바탕으로 채점자의 인지 부하를 경감하기 위해 필요한 프로그램의 주요 기능으로서 (1)주요 내용 요소에 대한 텍스트 자동 분석 및 표시 기능, (2)주요 표현 요소에 대한 텍스트 자동 분석 및 표시 기능, (3)관련 채점 기준 노출 기능, (4)채점 근거 저장 기능, (5)비슷한 수준의 글 검색 기능 등을 제안하였다. 또한 구체적으로 채점 프로그램의 UI/UX 설계 사례를 제안하였다. It is known that the Automated Writing Evaluation(AWE) system developed overseas has limited use in the classroom-based writing assessment situation. The reason is primarily due to the design method of the existing AWE systems. Therefore, in this study, as an alternative to improve this, it was proposed to develop an AWE system according to a cognitive engineering design method. Accordingly, according to the cognitive engineering design approach, the cognitive load factors for each detailed scoring process were extracted by exploring the prior studies on the scorer's cognitive process and the scorer's cognitive load during the scoring process. Also, based on this, the main functions of the program necessary to reduce the cognitive load of the scorer are (1) automatic text analysis and display function for main content elements, (2) automatic text analysis and display function for main expression elements, (3) ) related grading standards exposure function, (4) scoring basis storage function, and (5) similar level text search function were proposed. Finally, a specific design example of the scoring program was proposed.

Age-specific findings on lifestyle and trajectories of cognitive function from the Korean Longitudinal Study of Aging

Seungju Lim(Seungju Lim),Eunyoung Yoo(Eunyoung Yoo),Ickpyo Hong(Ickpyo Hong),Ji-Hyuk Park(Ji-Hyuk Park) 한국역학회 2023 Epidemiology and Health Vol.45 No.-

OBJECTIVES: Few longitudinal studies have explored age-related differences in the relationship between lifestyle factors and cognitive decline. This study investigated lifestyle factors at baseline that slow the longitudinal rate of cognitive decline in young-old (55-64 years), middle-old (65-74 years), and old-old (75+ years) individuals. METHODS: We conducted an 11-year follow-up that included 6,189 older adults from the Korean Longitudinal Study of Aging, which is a cohort study of community-dwelling older Koreans. Lifestyle factors, including physical activity, social activity (SA), smoking, and alcohol consumption were assessed at baseline. Cognitive function was measured at 2-year intervals over 11 years. Latent growth modeling and multi-group analysis were performed. RESULTS: The influence of lifestyle factors on the rate of cognitive decline differed by age. Smoking at baseline (-0.05; 95% confidence interval [CI], -0.11 to -0.00, per study wave) accelerated cognitive decline in young-old individuals, whereas frequent participation in SA at baseline (0.02; 95% CI, 0.01 to 0.03, per study wave) decelerated cognitive decline in middle-old individuals. None of the lifestyle factors in this study decelerated cognitive decline in old-old individuals. CONCLUSIONS: Cognitive strategies based on modifiable lifestyle factors such as smoking cessation in young-old individuals and frequent SA participation in middle-old age individuals may have great potential for preventing cognitive decline. Because the influence of lifestyle factors varied by age group, age-specific approaches are recommended to promote cognitive health.

On the -key toy-construction as Implicit Causatives

Seungju Yeo 한국중원언어학회 2019 언어학연구 Vol.0 No.51

The -key toy-construction is sometimes analyzed as periphrastic passives. The passive analysis, however, faces empirical and theoryinternal problems, suggesting that it may not be passives. It is instead proposed that they are a kind of causatives whose causers are implicit. -key is a phonological substantiation of a functional head licensing a causee. Both -key ha- and -key toystructures share a common complement whose head is realized as -key. The shared complement denotes a caused event. The difference between the two periphrastic constructions resides in the nature of the causative verbs involved. The causative auxiliary verb -ha projects its external argument, the causer, while the other “causative” auxiliary verb -toy does not. This “unaccusative” causative verb suppresses the causer on a par with a passivization suppresses an external argument, which is sometimes realized as an adjunct. The -key toy-construction is a causative whose causer is not present while the periphrastic causative explicitly projects a causer.

Get Opportunities from the middle of difficulty: The effect of incumbents’ problems on market entry of entrepreneurial firms

Seungju Lee(이승주),Seungho Choi(최승호),Sang-Joon Kim(김상준) 한국경영학회 2021 한국경영학회 통합학술발표논문집 Vol.2021 No.8

Building on literature in entrepreneurship and organizational theory, This study examines the effect of market problems of incumbents on entrepreneurial firms’ market entry. Through 20 U.S. domestic direct flight routes during 1995 - 2019, this study examines the likelihood of entrepreneurial airlines’ route entry under greater incumbents’ market problems. We find that the likelihood of entrepreneurial firms’ market entry increases when a market has greater incumbents’ problems. Simultaneously, we find that higher market concentration strengthens the relationship between incumbents’ market problems and entrepreneurial firms’ market entry. These findings show that existing market problems could be a catalyst for entrepreneurial firms’ market entry. Additionally, our finding provides a new perspective for resource partitioning theory by suggesting entrepreneurial firms’ market entry to a problematic mainstream market, not the periphery.

Telicity and iss-headed Periphrases

Seungju Yeo 한국언어학회 2018 언어 Vol.43 No.3

This paper proposes a morphosyntactic characterization of -e and -ko found in iss-headed perfectives. They are exponents of the functional head Telic whose primary function is to encode whether or not an event has a culmination point specified in the event description. [TELOS] is an uninterpretable feature of Telic that effectively performs this primary function; it has to be checked off. This forces a DP to raise to [SPEC, Telic[TELOS]], which is subject to the locality principle MLC. The morphosyntactic computation of telicity via Telic, under the guidance of MLC, gives rise to the non-agentive telic intransitivity of the suffix -e. Being a telic marker, this suffix is a spell-out of the Telic[TELOS].

Concurrent Validity and Test-retest Reliability of the Core Stability Test Using Ultrasound Imaging and Electromyography Measurements

Seungju Yoo,Nam-Gi Lee,Chanhee Park,Joshua (Sung) Hyun You 한국전문물리치료학회 2021 한국전문물리치료학회지 Vol.28 No.3

Background: While the formal test has been used to provide a quantitative measurement of core stability, studies have reported inconsistent results regarding its test-retest and intra-observer reliabilities. Furthermore, the validity of the formal test has never been established. Objects: This study aimed to establish the concurrent validity and test-retest reliability of the formal test. Methods: Twenty-two young adults with and without core instability (23.1 ± 2.0 years) were recruited. Concurrent validity was determined by comparing the muscle thickness changes of the external oblique, internal oblique, and transverse abdominal muscle to changes in core stability pressure during the formal test using ultrasound (US) imaging and pressure biofeed-back, respectively. For the test-retest reliability, muscle thickness and pressure changes were repeatedly measured approximately 24 hours apart. Electromyography (EMG) was used to monitor trunk muscle activity during the formal test. Results: The Pearson’s correlation analysis showed an excellent correlation between trans-verse abdominal thickness and pressure biofeedback unit (PBU) pressure as well as internal oblique thickness and PBU pressure, ranging from r = 0.856–0.980, p < 0.05. The test-retest reliability was good, intraclass correlation coefficient (ICC1,2) = 0.876 for the core stability pressure measure and ICC1,2 = 0.939 to 0.989 for the abdominal muscle thickness measure. Conclusion: Our results provide clinical evidence that the formal test is valid and reliable, when concurrently incorporated into EMG and US measurements.

Wet chemical etched CdTe thin film solar cells

Seungju Chun,Seung-Hun Lee,정영훈,Jong Seong Bae,김지현,김동환 한국물리학회 2013 Current Applied Physics Vol.13 No.1

Wet chemical etching process on as-deposited CdTe surface using nitric-phosphoric (NP) acid improved the efficiency of CdS/CdTe solar cells from 10.1% to 13.8%. Nitric-phosphoric (NP) acid solution etched native oxide (TeO2) layer and resolved excess cadmium on CdTe surface. After the heat treatment process activated the CdCl2, CdO layer which was believed to be a diffusion barrier of chlorine did not grow on the etched CdTe surface and new (VCd 2 e2ClTe 1þ)0 complexes was located at EV þ 0.045 eV. New (VCd 2 e2ClTe 1þ)0 complexes acted as a shallow acceptors and induced to improve Voc and Jsc. The surface of CdTe thin film has been studied using Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and low temperature Photoluminescence (PL).
