A Constraint-based Approach to Affixation in English: Vowel Alternation and Stress Change

오관영 국제언어인문학회 2017 인문언어 Vol.19 No.2

The purpose of the study is to account for vowel-laxing and tensing by suffixation in English through constraint-analyses on the assumption that a vowel was inserted before some suffixes, with or without stress change depending on certain contexts. There is a view that while vowel-initial suffixes cause such phonological phenomena, consonant-initial suffixes are not responsible for them. When we examined some instances, it was observed that several Class I suffixes begin with /i/, such as -ity, -ify, -ic, -ial, -ian, and -ious which were associated with vowel-laxing (Yip 1987:465). Therefore, we identify a possible cause of complex phonological effects as being vowel-insertion in some suffixes (Aronoff 1976, Fudge 1984, Yip 1987, Raffelsiefen 1998), resulting in allomorphs, and -ic containing a stem-forming vowel. To present the basis of vowel-insertion in some suffixes, we consider the suffixes from historical and theoretical perspectives. As for vowel-laxing in suffixation, we look into rule-based approaches, such as Halle and Mohanan’s (1985) collapsed Shortening, Yip’s Pre-Cluster Shortening, and Roca and Johnson’s (1999) mora-based analysis, but these analyses do not provide a satisfactory explanation for vowel-laxing with stress change. Regarding vowel-tensing in suffixation, we also review Halle and Mohanan’s rule, but it does not give us an appropriate explanation for tensing, not to mention the stress change. Therefore, we look for constraint-based approaches as an alternative, and finally can account for the complex phonological phenomena more consistently and concisely than the rule-based approaches.

운율 측면과 조화이론 측면의 비교: 강세 현상에 대해

오관영,Oh, Kwan-Young 한국영어어문교육학회 2002 영어어문교육 Vol.7 No.2

The purpose of this paper is to explain stress shift and its following segmental variations when some suffixes are added to the bases. In the past those were analyzed in stress or vowel laxing phenomenon separately, but rather those should be analyzed in one framework compositively. Therefore in this paper I will introduce a new theory, which is known as Harmonic theory, and confirm that it can solve the problems related with stress and vowel laxing simultaneously. The first thing, as a prosodic approach I am going to analyze vowel laxing according to Liberman & Prince (1977), Burzio (1993), and then next to go to the Harmonic theory approach. Within the theory I will analyze the phonological phenomena harmoniously through the important three levels, M-level, W-level, P-level. Therefore this paper is to show that from the comparison between the prosodic analysis and the Harmonic analysis, what is more natural and harmonious analysis is based on the Harmonic approach.

The purpose of this study is to compare the quality and characteristics of matching DEMs by using KOMPSAT-3 stereo pair capture in in-track and cross-track. For this purpose, two stereo pairs of KOMPSAT-3 were collected that were taken in the same area. The two stereo pairs have similar stereo geometry elements such as B/H, convergence angle. Sensor modeling for DEM production was performed with RFM affine calibration using multiple GCPs. The GCPs used in the study were extracted from the 0.25 m ortho-image and 5 meter DEM provided by NGII. In addition, matching DEMs were produced at the same resolution as the reference DEMs for a comparison analysis. As a result of the experiment, the horizontal and vertical errors at the CPs indicated an accuracy of 1 to 3 pixels. In addition, the shapes and accuracy of two DEMs produced in areas where the effects of natural or artificial surface land were low were almost similar. 본 연구의 목적은 in-track과 cross-track에서 촬영된 KOMPSAT-3 입체영상으로 제작된 매칭 DEM의 품질 및 특성을 비교 분석하는 것이다. 이를 위하여 동일 지역을 촬영한 두 쌍의 KOMPSAT-3영상을 수집하였다. 두 쌍의 입체영상은 B/H, convergence angle 등 스테레오 기하 요소가 거의 유사하다. DEM 제작을 위한 센서모델링은 수 개의 지상기준점를 이용한 RFM affine 보정으로 수행하였다. 연구에 사용된 지상기준점은 NGII에서 제공하는 0.25 m급 항공정사영상과 5 m급 DEM에서 추출하였다. 또한, 참조 DEM과 동일한 해상도로 매칭 DEM을 제작하여 상호간 비교 분석을 실시하였다. 실험 결과, 검사점의 수평 및 수직 오차는 1~3픽셀의 정확도를 나타냈다. 또한, 자연 또는 인공적 지형지물의 영향이 적은 지역에서는 생성된 두 DEM의 형태 및 정확도가 거의 유사하였다.

Oh, kwan-Young. 1998. The Harmonic approach on the trisyllabic laxing. Studies in Phonetics, Phonology and Morphology 4, 155-174. The purpose of this paper is to suggest the new device to be able to deal with the unexplainable by the previous analyses about the trisyllabic laxing. The model is based on the Harmonic Theory. The reason this paper adopted the theory is the foot structure under phonological word, which is the unit to explain the stress shift and vowel laxing compositively in English word. In the past the stress and vowel laxing in English have been treated in Lexical Theory and Metrical Theory separately. But in those approaches there are the serious errors in analyzing the phenomenon, trisyllabic laxing. That is, the stress shift and vowel laxing are not the separate, but rather the compositive operation associated with each other closely. Therefore this paper will show more appropriate explanations through the new approach, which depends on the revised Rhythm rule and the new foot structure I will suggest, and so can resolve the problems of the unsolved, exceptional examples.

KOMPSAT-3A 중적외선 영상의 공간해상도 복원 기법

오관영,이광재,정형섭,박숭환,김정철 대한원격탐사학회 2019 大韓遠隔探査學會誌 Vol.35 No.6

The KOMPSAT-3A is a high-resolution optical satellite launched in 2015 by Korea Aerospace Research Institute (KARI). KOMPSAT-3A provides Panchromatic (PAN-0.55 m), Multispectral (MS- 2.2 m), and Mid-wavelength infrared (MIROR-5.5 m) image. However, due to security or military problems, MIROR image with 5.5m spatial resolution are provided down sampled at 33 m spatial resolution. In this study, we propose spatial sharpening method to improve the spatial resolution of MIRrd image (33 m) using High Frequency (HF) image and optimal fusion factor. Using MS image and MIRrd image, we generated virtual high resolution (5.5 m) MIROR fus image and then compared them to actual high-resolution MIROR image. The test results show that the proposed method merges the spatial resolution of MS image and the spectral information of MIRrd image efficiently. KOMPSAT-3A는 2015년 한국항공우주연구원(KARI)이 발사한 고해상 광학위성으로 0.55 m 급 전정색영상(PAN), 2.2 m 급 다중 분광 영상(MS) 그리고 5.5 m 급 중적외선 영상(MIROR)을 제공한다. 그러나 보안 또는군사적인 문제로 인해 공간 해상도 5.5 m MIROR 영상은 33 m 공간해상도로 down-sampling된MIRrd 영상으로 제공된다. 본 연구에서는 고주파(HP) 영상과 최적 융합 계수를 이용하여 MIR_rd 영상의 공간해상도를 복원하는방법을 제안하였다. MS 영상과 MIRrd 영상을 이용하여 가상의 MIROR fus 영상을 제작하였으며, 이를 실제 MIROR 영상과 비교 분석하였다. 실험 결과, 제안된 방법이 MS 영상의 공간해상도와 MIRrd 영상의 분광정보를 효과적으로 조합 하였다는 것을 보여주었다.

A Phonological Approach to the Contextual Variances of the English Lateral /l/

오관영 21세기영어영문학회 2014 영어영문학21 Vol.27 No.3

The purpose of this study is to explore distributional variants of English /l/s which are differently realized depending on their contexts, to suggest different methods of analysis through feature geometry, and to compare two contrastive analyses of variants in English dialects, GA and RP, which are performed by rule orderings and level approach each differently. Generally, allophony of the English lateral is shown in two types of forms, prevocalic (clear or light)-l and post-vocalic (dark)-l. These are phonetically distinguishable. However, when we look into some examples, there are other cases in which the /l/s become deleted as in talk or syllabic -ls as in bottle. This paper attempted to account for variants of /l/ in phonological approaches. First, this study showed that, in the cases of the dark-l and l-deletion in monosyllabic words, different methods of analysis suggested in feature geometry with phonetic information were clearer and more concise than the approaches based on rule orderings. Second, for the identification of the clear and dark-l, this paper introduced level approaches to account for these variations. As a result, they offer briefer and more convincing explanations to variants in words which were followed by morphological boundaries or were disyllabic than approaches based on rule orderings.

A Comparative Analysis Study of Phonological Approaches to /s/ voicing

오관영 대한영어영문학회 2023 영어영문학연구 Vol.49 No.4

In general, the voicing of /s/ leading to its realization as [z] in intervocalic positions has been approached in very complex ways within phonology. The aim of this study is to offer a more concise explanation of /s/ voicing through a level-structure approach, without the complexity of derivative processes arising from rule orderings or rule domains. We initially explored the analytical methods related to /s/ voicing based on theoretical frameworks, addressing their specific issues in detail, which illuminated the complexities and limitations of their explanations. As a fresh perspective, we introduced a level-structure approach by proposing the s-Voicing rule on level-structure (SVL). We presented succinct explanations for /s/ voicing in three cases: forms with the prefix re, forms with the stem sist, and monomorphemic forms. Particularly, we posited an Inherent Auto-feature Endowment (IAE) condition to account for the monomorphemic forms. As a result, we can provide concise insights into the forms related to /s/ voicing within the level-based approach.
