모음체계의 변화와 방언접촉

김선회(Sun-Hoi Kim) 한국중원언어학회 2010 언어학연구 Vol.0 No.16

The goal of this paper is to present an Optimality-theoretic approach to the phenomenon that the change of a vowel system is activated by the most unstable vowel in the vowel system and it is also influenced by external factors, such as dialect contact. For achieving this goal, this paper focuses on the analysis of the loss of a low back vowel in Korean. In the framework of Optimality Theory (McCarthy & Prince 1993, Prince & Smolensky 1993/2004), this phenomenon is analyzed in relation to conflicting constraints. The analysis proposed by this paper shows that the vowel shift in Middle Korean is a result of the constraint ranking where a listener-oriented faithfulness constraint outranks speaker-oriented faithfulness ones. It further shows that the loss of the Korean low back vowel is influenced by dialect contact and its influence is formalized by the constraint ranking where an output-output faithfulness constraint outranks input-output faithfulness ones.

A tone - domain interactive approach to binary spread and shift of high tone

김선회(Sun-Hoi Kim) 한국음운론학회 2005 음성·음운·형태론 연구 Vol.11 No.2

This paper focuses on the binary (bounded) spread and shift of high tone in the case where high tone is specified on a tone-bearing unit in the input. The main idea of this paper is that high tone is realized only within the domain for high tone. In this view, the spread and shift of high tone are both domain-internal processes. Therefore, this view requires that the domains for high tone should be optimally constructed. In this paper, it is shown that this view adequately explains various ways to realize the input high tone in the output. The parametric interactions of constraints in this view have applied to four Korean tonal dialects, that is, Hoylyeng, Samchek, Taykwu, and Pwukcheng Korean. In this case study, it is shown that the approach proposed in this paper accounts for the rich variation of tonal phenomena relevant to binary spread and shift of high tone in the Korean tonal dialects.

[i]/Ø 교체 접미사의 입력형 설정에 관한 쟁점 재고찰: /i/로 시작하는 입력형을 위한 /h/-탈락으로부터의 증거

김선회 ( Sun Hoi Kim ) 한국 현대 언어학회 2009 언어연구 Vol.25 No.3

This paper revisits an issue on the inputs of [i]/Ø-alternating suffixes in Korean. This issue has been left with wide disagreement among previous studies. This paper attempts to support one of the conflicting views: the /i/-initial forms should be the inputs of these suffixes. To provide crucial evidence for this view, this paper analyzes the relatedness of /h/-deletion and [i]/Ø alternation, focusing on the forms where a stem-final /h/ is followed by an [i]/Ø-alternating suffix. In this analysis, it is shown that the stem-final /h/ would not be deleted if the inputs of these suffixes could not begin with /i/. Because the actual outputs of /h/-final stems followed by these suffixes do not include the final [h], this situation tells us that the inputs of these [i]/Ø-alternating suffixes should begin with /i/. Accordingly, this analysis leads to the conclusion that the /i/-initial forms are the inputs of [i]/Ø-alternating suffixes. (Chung-Ang University)

한국어 체언말 저해음 변이를 위한 복수기저형 확률문법

김선회(Kim, Sun-Hoi),김하나(Hana Kim) 한국음운론학회 2016 음성·음운·형태론 연구 Vol.22 No.2

This paper aims to propose a probabilistic grammar with multiple underlying representations (UR’s) for Korean noun-final obstruent variation and to analyze the influence of UR choice on this variation. The grammar is based on Pater et al.’s (2012) multiple UR Maximum Entropy model, where UR constraints are proposed to require a particular UR corresponding to the meaning/concept of a given morpheme or word. It consists of weighted constraints learned from the training data which are a result of the picture-presented production experiment conducted for this variation. This grammar produces the probabilitic distribution of variation for Korean obstruent-final nouns. The probabilistic distribution tells us that this variation consists of three different types of variation. One is a (traditional or etymological) UR-preferred type of variation (ch-final and ph-final nouns), another is a substitution-preferred one (kh-final nouns) and the other is the variation which a phonological process strongly influences (th-final nouns). This phenomenon shows that the variation is difficult to explain without considering the UR factor. Further, in this paper, it is shown that the UR choice is determined by the interaction between UR constraints, faithfulness constraints and markedness constraints.

한국어 단어들의 음절 기반 음운이웃 네트워크

This study analyzed the syllable-based phonological neighborhood networks (PNNs) of Korean words. The network-theoretic representation of the lexicon has provided new insights on cross-linguistic and language particular factors in the composition of the phonological lexicon (Vitevitch, 2008; Shoemark et al., 2016, among others). This study draws from the literature the notion of phonological similarity as a network feature, but, unlike previous phonemic approaches, it assumes syllables as the unit of phonological similarity (Mehler et al., 1981; Kwon et al., 2006, 2011). We collected 83,881 polysyllabic words from a Korean corpus. According to the various network measurements on them, the syllable-based PNNs were similar to conventional phonemic-based PNNs in satisfying requirements for small-world networks, being influenced by the lexicon size and having a high value of assortativity by degree. However, they also showed different characteristics from phoneme-based PNNs: syllable-based PNNs had larger giant clusters, average degrees, and cluster coefficients, and they showed smaller values of the average shortest path length. The insights from the PNN analysis are significant since they can help answer empirical questions of phonological word processing and word acquisition.

한국 환경사회학의 지적 구조

어떤 학문 분야의 특성을 이해하는 좋은 방법 가운데 하나는 그 학문 분야의 지적 구조가 어떠하며, 어떠한 변화 과정을 거쳐 왔는지를 살펴보는 것이다. 이 연구는 한국 환경사회학의 지적 구조를 분석하고 이를 시각화하여 제시하는 데 목적이 있다. 한국 환경사회학의 공식적인 학술지인 《ECO》의 창간호부터 2015년 6월까지 실린 논문들의 제목에 나온 단어들에 대해 동시출현단어분석을 실시한 결과 한국의 환경사회학에서 가장 빈번하게 출현하는 단어는 <환경>, <사회>, <생태>, <한국>임을 발견하였다. 한국의 환경사회학은 환경과 사회의 상호작용에 대한 연구관심을 기초로 한 환경문제의 사회학이라는 정체성을 가지고 있으면서 한국적 상황과 맥락에 대한 연구가 중심을 이루고 있었다. 다만 최근 들어 한국 환경사회학의 연구관심이 보다 확장되어 <에너지>, <기후>에 대한 연구가 증가하는 경향을 보였다. One of the best ways to understand the characteristics of an academic field is to investigate the knowledge structure of the academic field and the aspect of its change. This paper aims to analyze and visualize the knowledge structure of environmental sociology in Korea. In this paper, it is shown that the words environment, society, ecology, and Korea are the most frequently occurring ones in the titles of articles published from the first issue of 《ECO》 till its 15(2) issue of June, 2015. The results of analysis show that environmental sociology in Korea has been interested in the interaction between environment and sociology, focusing on the context of Korea, and is characterized as a ‘sociology of environmental problem’. It is also shown that the research interest has recently extended to the issues of energy and climate.

영시 약강5보격에서의 어휘적 전도에 대한 최적성 이론적 접근

김선회(Kim Sun-Hoi),조희정(Heejeong Cho) 한국음운론학회 2006 음성·음운·형태론 연구 Vol.12 No.1

  Lexical inversion refers to the appearance of the linguistic sequence stressed-stressless in the same word in W(eak)S(trong) position of the meter. Focusing on the lexical inversion in the iambic pentameter of English poetry, this study investigates the metrical grammar that constitutes the intuitive knowledge of poets on metricality in versifying the iambic pentameter with lexical inversion. Applying Optimality Theory, which is a dominant theory of phonology, to explaining the metrical grammar, this study proposes that the evaluation part consisting of hierarchically ranked constraints functions to evaluate the well-formedness of input metrical forms but does not derive the repaired forms from ill-formed inputs. Within this proposal, three major constraints ALIGN-L(PPh), Faithfulness Constraints (IDENT(location), MAX(σ), DEP(σ)), and STRESS MATCHING interact with one another in the ranking ALIGN-L(PPh)>>Faithfulness Constraints>>STRESS MATCHING for evaluating the well-formedness of input metrical forms in the iambic pentameter. It is shown in this study that the positional restriction that lexical inversion occurs in the left edge of phonological phrase is adequately explained by the interaction of the three major constraints within their proposed ranking.

한국어의 단어 빈도와 단어와 음절의 분포적 특성

김선회(Kim, Sun-Hoi),남성현(Sunghyun Nam) 한국음운론학회 2020 음성·음운·형태론 연구 Vol.26 No.3

This paper analyzes the distributional characteristics of Korean words and syllables in relation to word frequency. Five sub-lexicons of Korean are made on the basis of word frequency for this study. The sub-lexicons are compared with respect to the distributions of words and syllables. The analysis shows that the sub-lexicon of high frequency words (i.e. use frequency of 1,500 times or more) exhibits a marked difference in the distributional characteristics of words and syllables. According to the analysis, when other words are added to the sub-lexicon of high frequency words, meaningful changes are observed in the distributional characteristics. The analysis shows that word frequency is an important factor that should be considered in the analysis of the distributional characteristics of words and syllables in Korean.
