Rule Ordering Revisited: An Optimality Theoretic Account

Seok-keun Kang 한국음운론학회 1997 음성·음운·형태론 연구 Vol.3 No.-

Kang, Seok-keun. 1997. Rule Ordering Revisited: An Optimality Theoretic Account. Studies in Phonetics, Phonology and Morphology 3, 25-42. The purpose of this paper is to reconsider obstruent neutralization, nasalization, /I/-nasalization and /n/-lateralization in Korean within the framework of Optimality Theory and to explore constraints and their hierarchies in an account of the interactions among the rules. I show that the interactions can be straightforwardly accounted for in terms of some ranked, violable constraints without recourse to extrinsic rule ordering and other stipulations which were indispensable in earlier analyses (e.g., Kim-Renaud 1974 and K-H Kim 1987). Doing this, I also show that the Obligatory Contour Principle can be dispensed with in Optimality Theory. (Wonkwang University)

A Correspondence Account of the Alternations of English Nasal-Final Prefixes

Kang, Seok Keun 대한언어학회 1999 언어학 Vol.7 No.3

Seok-keun Kang. 1999. A Correspondence Account of the Alternations of English Nasal-Final Prefixes. Linguistics 7-3, 157-174. The purpose of this paper is to reconsider the phonology of English nasal-final prefixes within the framework of Optimality Theory, especially in terms of correspondence. In this paper, I show that compared with previous analyses employing rules and their extrinsic orderings, a constraint-based approach can give a better account of the phenomenon. In order to do this, following Kenstowicz(1996), I posit a constraint of Uniform Exponence. In particular I assume that the candidates for the allomorph of a prefix are evaluated so as to minimize allomorphic difference in the realization of the morpheme itself. I show that given these assumptions, we can account for assimilation of the prefix-final nasals in a unified way by appropriately ranking the Uniform Exponence constraint among the other constraints.

Some Phonological Phenomena in Korean : an Optimality Theoretic Account

Kang, Seok Keun 대한언어학회 1995 언어학 Vol.3 No.-

Kang, Seok-keun (1995) Some Phonological Phenomena in Korean: an Optimality Theoretic Account. Linguistics vol. 3. The purpose of this paper is to reconsider obstruent neutralization and consonant cluster simplification in Korean within the framework of Optimality Theory. Considering the interaction of the Basic Syllable Structure Constraints proposed by Prince and Smolensky (1993), first, I claim that in Korean, ONS and -COD are dominated by FILL and PARSE. Second, I consider some theoretical devices for handling obstruent neutralization and consonant cluster simplification in an Optimality Theory framework, and assert that these phonological phenomena can be accounted for in a unified way in terms of a ranking of constraints.

An optimality theoretic account of phonological opacity in English

Seok-Keun Kang 한국음운론학회 2000 음성·음운·형태론 연구 Vol.6 No.2

Kang, Seok-keun. 2000. An optimality theoretic account of phonological opacity in English. Studies in Phonetics, Phonology and Morphology 6.2. 307-332. Since the inception of Optimality Theory (Prince and Smolensky 1993), opacity has been one of the most contentious issues in the theory. In this paper, considering palatalization and spirantization in English which show opacity effects, I claim that neither a traditional OT analysis nor a sympathy analysis can provide a satisfactory account of them. In order to account for the opacity effects, I assume that suffixes can impose phonological restrictions on the base to which they are attached. Given some morpho-phonological constraints which regulate the relationship between suffixes and the words, we can account for the opacity effects in a satisfactory way. (Wonkwang University)

Linking and Intrusive r in English a Correspondence Account

Kang, Seok Keun 대한언어학회 1998 언어학 Vol.6 No.2

Kang, Seok-keun. 1998. Linking and Intrusive r in English: a Correspondence Account. Linguistics, 6-2, 243-262. The purpose of this paper is to reconsider linking and intrusive r in English. Accounting for the phenomenon within the framework of Correspondence Theory (McCarthy and Prince 1993, 1995), I show that linking and intrusive r can be interpreted as glide formation, and that once given this assumption, the phenomenon can be accounted for in a unified, satisfactory way in terms of a ranking of constraints.

An optimality theoretic account of the status of onglides in American Engish

Seok-Keun Kang 한국음운론학회 2001 음성·음운·형태론 연구 Vol.7 No.1

Kang, Seok-keun. 2001. An optimality theoretic account of the status of onglides in American English. Studies in Phonetics, Phonology and Morphology 7.1. 1-20. This paper discusses the status of the onglides /w/ and /y/ in English. Specifically focussing on the different behaviors between the two glides in postconsonantal position, I show that compared with previous rule-based analyses, a constraint-based theory can provide a better account of the phenomena. To this end, I assume that no syllable structures are present in input. Given this assumption, we can account for the distributions of the onglides /w/ and /y/ in a satisfactory way by making use of some constraints on surface representations.(Wonkwang University)

한국 학생들의 영어 어두자음 발화학습에 관한 실험 연구

강석근,이희천 서울대학교 어학연구소 2002 語學硏究 Vol.38 No.1

The purpose of this paper is to examine through experiment if Korean students can learn sounds like /r/, /f/, /b/ and /v/ precisely, sounds which Korean does not contain, and to discover methods whereby this learning may be accomplished. To this end, we prepared two kinds of test materials with 30 questions each, consisting of pairs with /l, r/, /f, p/, and /b, v/ in word-initial positions. In the tests, 40 third-year students from Janghang Technical High School served as subjects. The subjects were divided into two groups: an experimental group and a control group. The tests consisted of two steps. First, we examined each group's pronunciation ability of the above consonants in word-initial positions. Next, after teaching the experimental group the differences between the consonants above with special programs, we examined their degree of improvement. The results showed that the pronunciation ability of the experimental group improved more than that of the control group. In conclusion, although most of the subjects of the control group had difficulty in pronouncing the sounds that Korean does not contain, they improved their pronunciation ability to some degree by learning the place and manner of articulation, and through reetitive practice.

벤처 기업 지원에 대한 이론적 연구

강대석,오근엽 충남대학교 경상대학부설 경영경제연구소 1999 경영논집 Vol.15 No.2

본 논문에서는 벤처기업 지원의 효과에 대하여 분석하고 정부가 이를 지원하지 않으면 시장의 실패가 발생하는 이유를 이론적인 측면에서 규명하였다. 먼저, 급격한 기술혁신이 이루어지는 상황에서 대기업에 비해서 벤처기업이 연구개발의 상업화에 비교우위가 있음을 규명하였고 고용창출에도 효과가 있을 수 있음을 분석하였다. 다음으로, 이 분야에서의 시장의 실패는 외부경제, 정보의 비대칭성, 리스크, 자금 회수에서의 장기간 소요, 관리비용 등이 주요 요인임을 보였다.

CMOS VLSI의 IDDQ 테스트세트 간략화에 관한 연구

김강철,송근호,한석봉 진주산업대학교 1996 論文集 Vol.35 No.-

This paper proposes a dynamic compaction algorithm which can detect intra-bridging faults for IDDQ testing in CMOS VLSI. X_gates which have X(don't care) values in the input of the gate may exist in the circuit after a test pattern in chosen. The compaction algorithm assigns the logic value 1 or 0 that can be applied to the primitive fault pattern to X in the X_gate, and it detects all detectable faults for a test pattern. The simulation results in the benchmark circuits show that the fault coverage of this dynamic compaction algorithm is much enhanced compared with the conventional static compaction algorithms, and the resulting test vector reduction is up to 30%.
