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

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.

Morphosyntax of Telicity and Pseudo-aspectual Structures

Seungju Yeo 한국중원언어학회 2018 언어학연구 Vol.0 No.49

Based on the morphosyntactic characterization of grammatical aspect, this paper argues that certain purported aspectual structures—those which are based on motion verbs, reflexive verbs, and so on—are not aspectual in nature, but involve a full-fledged lexical iss- of ‘to exist/stay,’ denoting a coordination of two sequentially connected events. An aspectual iss-, on the other hand, just adds functional information that the event of the preceding verb is to be aspectually specified. They are structurally distinct from periphrases of grammatical aspect and hence exhibit properties not associated with aspectual sentences headed by iss-. The specification of the grammatical aspect headed by iss- depends on Telic whose morphosyntactic computation via the uninterpretable [TELOS] amounts to a non- agentive telic intransitive event, capturing the telic intransitivity condition responsible for the systematic gaps associated with iss-headed perfectives.

A Key to Unifying -key

Seungju Yeo 한국중원언어학회 2020 언어학연구 Vol.0 No.57

This paper proposes that the suffix –key is a spell-out of a functional head dedicated for licensing a causee in expressing causation in Korean. This suffix is observed in such syntactic environments as periphrastic causatives, periphrastic “passives” and resultatives, raising a question as to why and how these syntactic structures have come to employ the same suffix, despite their interpretive differences. It is observed that periphrastic causatives, periphrastic “passives” and resultatives involve a caused event in their morphosyntactic and interpretive deployment. There exists a systematic correlation between the verbal suffix under consideration and the caused event interpretation. It is proposed that under semantic differences lies a common morphosyntactic piece which denotes a caused event/state and its head is spelled out as -key. The three syntactic structures share the same morphosyntactic structure and are contextual variations of denoting causation in Korean. The presence of -key in such varied syntactic environments is not an accident, but a natural consequence of the morphosyntax of causee at work.

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).
