  • The purpose of this paper is to show that the solutions of the problem for the anaphor ocured in korean senstence, by means of one-direction activated chart parsing leaded by a head. This is the phenomenon frequently occured in the conversation of natural language and the part necessarily required in the construction of natural language processing system for the practical use. To solve the problem of anaphor in the korean language, we have computerized definition and the management conditions necessary in the semantic classification between the anaphor and its antecedent and index are added in the feature structure in lexicon. To deal with anaphor in parser and algorithm is proposed to solve the problem for anaphor. The range of management of pareser is extended to solve the problem for anaphor of the indeclinable parts of speech in korean occured in all the sentences the parser HPSG developed previously manages.

  • The aim of this paper is to describe the prosodic structure of Korean related to the syllable duration varying with its positional difference. An attempt is made in this study to analyze and describe the concrete correlation between the syllable lengthening and its position in the utterance at the initial and final positions. Using the syllable [na] at the final and initial position of a prosodic phrase in the Korean version of 'the North Wind and the Sun', it has found that the ratio of phrase final versus phrase initial syllable lengthening was approximately 1.8:1 for 4 subjects taking part in the test. In the case of nonsense data, we found that the ratio was approximately 1.6:1 for 2 out of 3 subjects. The results of this study might indicate that Korean tends to have a high rate of final lengthening. We can tentatively classify it, therefore, as a stress-timed language. Still, there is no denying that further studies should be done before we can be absolutely certain about the classification of languages along the dichotomy scale.

  • Oral mucormycosis is a fungal infection observed mainly in elderly immunocompromised patients. In rare instances, the disease occurs in healthy individuals and those patients that are below preschool age. Although this condition mainly involves the maxilla, it may also manifest in any part of the oral cavity based on the source of infection. Mucormycosis of the maxilla spreads rapidly, leading to necrosis of the palatal bone and palatal perforation. Such patients are usually rehabilitated using bone grafting or free flap surgeries. However, when surgeries are delayed, palatal prosthesis is an interim treatment modality that can prevent nasal regurgitation and aspiration of food or fluids. Palatal prostheses also help with mastication, speech, and swallowing. The present case describes a rare case of oral mucormycosis in an 18-month-old male involving the maxilla that was managed by palatal prosthesis.

  • Oral cancer treatment involves the surgical removal of all or part of the maxilla, leaving the patient with a defect that compromises the integrity and function of the oral cavity. The postoperative restoration of esthetics, deglutition, and speech shortens recovery time in the hospital and expedites the patient's return to the community as a functioning member. The surgical obturator is the proven treatment option in such situations. This article describes a simple technique to fabricate a surgical obturator that restores patient's original dentition and facial and palatal tissue form. The obturator fabricated with this technique utilizes the vacuum formed index of patient's original tissue form and duplicated partly in heat and partly in auto polymerizing acrylic resin. Duplication of the original tissue form helps patient to minimize the immense physiological trauma immediately after the surgical resection. The obturator fabricated with this technique supports soft tissues after surgery and minimizes scar contracture and disfigurement, and thus may have a positive effect on the patients' psychology.

  • Korean unvoiced phonemes consist of nonstationary parts comparing that the vowels and nasal consonants consist of quasi-stationary part. And some phonemes, which have smae point of articulation but differnt manner of articulation, has similar characteristics, so it makes to be hard to distinguish each other. A new method usin gchanges and characteristics of acoustic properties of these phonemes to improve recognition rate are proposed. And because these changes and cahracteristics evidently occur in continuous speech except some unvoiced consonants are articulated as voiced phoneme in case to be used as an midial between voiced phonemes, this method can be applied easily. The features of the frames extracted to represent each phonemes are used asinputs to the hierarchical neural network. And with these results final decision for phoneme recognition is made thorugh post processing which the new method is applied to. Through the experimental recognition results for 9 unvoiced consonants which belong to bilabial, alveolar, and velar phoneme series, 89.4% recognition rate to distinguish in same phoneme series is obtained, and 85.6% recognition rate is obtained in case of including cistinguishing phoneme series.

  • This paper is a study on the consonant recognition using neural network. First, the part of consonant was separated from the sound of vowel and consonant by the use of acoustic parameter. The rate of length vs. zero crossing rate in the sound of consonant had been studied by dividing each consonant into several groups. Finally, for the purpose of consonant recognition, the composite neural network which consists of a control network and several sub-network is proposed. The control network identifies the group to which the input consonant belongs and the sub-network recognizes the consonant in each group.

An Experimental Study on Focus Structures of English Utterances by Native Speakers and Korean Learners (원어민 화자와 한국인 학습자 영어 발화의 초점구조에 대한 실험음성학적 연구;협의초점과 광의초점을 중심으로)

  • In this study, we investigate ways that focus is realized in English utterances produced by native speakers of English and Korean learners. As compared to the previous studies which deal mainly with functional aspects of focus as a part of intonational structure, we attempt to provide more quantitative information on F0 and discover the extent to which Korean learners distinguish focus types in their English utterance production. On the test sentences designed to be disambiguated by correct focus realization, it is found that, even advanced-level Korean learners, unlike native speakers, hardly employ F0 to clarify the specific meaning of English utterances.
