This study was designed to determine (1) the effects of the following stop consonant on the vowel length in isolated bi-syllabic words, (2) the mechanism which renders vowels longer in duration before lax stops than tense stops, (3) where the aspiratory interval is included, in the vowel portion or the preceding consonantal portion and (4) the influence of the preceding consonants upon the duration of the following vowel. Measurements were made of five timing variables on acoustic signals as three native Korean speakers uttered isolated bi-syllabic /VCV/ words in which the vowel was identical, /$\alpha$/, and the C slot was filled with bilabial stops. Findings: (1) the vowel length before the lax stops was significantly longer than before the tense stops, while the difference in the vowel duration between the tense stops was insignificant or negligible, (2) the vowel length varied as a function of the articulatory force of the following consonants, regardless of the phonological unit of syllable, (3) The aspiratory interval is interpreted as a portion of the preceding consonant and (4) The effects of the preceding consonants on the final vowel length were not rule-governed.

The objective evaluation of velopharyngeal closure function is the key to diagnosis and therapy control of velopharyngeal incompetency. The aim of this study is to evaluate the aerodynamic and acoustic characteristics of the velopharyngeal closure function of patients who have developed velopharyngeal incompetency after management with speech aids. The test words were composed of sustained vowels /a/, /i/, /e/, /u/, /ja/, /je/, /wi/ and polysyllabic words /p'ap'i/, /siso/, /mami/ for measuring nasalance, The data was collected before the placement of the speech aids and one to three months after. The results were as follows: The nasalance score of the velopharyngeal incompetency speakers was higher than that of the normal control group, except for nasal sounds, and was decreased after placement of the speech aids, especially in high vowels /i/ (P<.01) and /wi/ (P<.05).

This study is designed for two purposes. The first one is to compare the realization and perception of English contrastive focus between Korean learners of English and native speakers of English. The second purpose is to study the phonological and phonetical features of contrastive focus by examining the results of production and perception experiments. English native speakers' results show that the English contrastive accents are generally accompanied by higher peak heights. The findings agree with the results of Bartels & Kingston (1994). Unlike native speakers of English, Korean speakers seem to be poor at relating the phonetical features of contrastive focus to their actual speech. Korean speakers' results are especially unsuccessful when the contrast is not distinctly grasped through syntactic structure, or when the function words are contrasted. Furthermore, Korean speakers' utterances tend to have pitch accents on every content word, whether the word is contrasted or not.

To the design of secret key, there are two types of basic approaches called the tame approach and the wild approach. In the tame approach we try to use only simple primitives such as linear feedback shift registers and to prove mathematical theorems about their cryptographic properties. In the wild approach we try to use crazy compositions of operations which mix a variety of domains in a nonlinear and nonalgebraic way. There are several papers which try to bridge this gap by considering semi-wild constructions. A T-function on n-bit words plays an important role in semi-wild constructions. In this paper we study the invertibility and the period of some T-functions. Especially we characterize some polynomials which has a single cycle property.

Synonym means that the conceptual meaning of the word is the same or similar while other meanings or function of language difference may exist. That is two or more identified names correspond with one sense and have the words with minor difference. Words with synonym relation are a set of same meaning but conceptual area or emotional color, language function can be identified. Therefore, the core research of synonym is the difference analysis and in general difference analysis is progress in the three aspects of Meaning, Pragmatic, and Semantic. However, the difference analysis is the most important. In this paper, the set of meaning item of synonym word 'Attack' is 'zheng', 'fa', 'tao', 'qin', 'xi'. We compare the meaning of five verbs and analyze the difference and characteristics.

The study analyzed a diachronic distribution, social meanings and social evaluations of ROOJIN. 'Headline Database of Newspaper Articles' and 'Balanced Corpus of Contemporary Written Japanese' by KOKKEN were used as research data. There were 305 newspaper articles (About 0.2%) which contained the word ROOJIN at 'Headline Database of Newspaper Articles'. The number of newspaper articles related to ROOJIN started to increase in a rapid rate in 1972 and 1973. They were also increased in 1976, from 1981 to 1987, 1992 and 1993. The reasons of increasing of newspaper articles related to ROOJIN on those 4 periods of time could be summarized as follows. Firstly, there was a increasement of ROOJIN who are lonely, are not able to move about freely or live alone. Secondly, the understanding of a symptom of aging called BOKE was necessary. Thirdly, there were negative evaluations in a society towards ROOJIN. There were 453 cases which contained the word ROOJIN at 'Balanced Corpus of Contemporary Written Japanese' on the data since 2000. The most frequently used words were ones that are related to senior care facilities. There were 109 cases (24%) which contain those words. '~SISETSU', '~SENTA-', '~HO-MU' were presented as words related to senior care facilities. Among them, 78 cases contained the word '~HO-MU' which was similar to a home with family members. The second most frequently used words were ones that are related to 'welfare for the aged' and they are led by 'medical care for the aged'. They occupied about 8%. Institutionalization of medical care for the aged, medical expenses, nursing were presented as words related to 'medical care for the aged'. Words that were related to 'welfare for the aged' led by 'senior care facilities' and 'medical care for the aged' occupied about 32% of research data. As mentioned above, problems of the aged in Modern Japan such as negative evaluations in a society towards ROOJIN, ROOJIN who are lonely, are not able to move about freely or live alone, BOKE could be identified by analyzing the data. Also, The frequent usage of words such as 'Home for the aged', 'medical care for the aged' and 'nursing' could be identified. The outcome of analysis suggested that a family traditionally had a function of solving problems of the aged but that function was reduced in modern Japan. It also suggested that there was a tendency to outsource problems of the aged as much as possible.

본 논문은 음성 신호의 Average Magnitude Difference Function (AMDF)에서 peaks (혹은 nulls)들을 찾는 알고리즘들을 제안하였다. AMDF 함수는 Autocorrelation Function (ACF)과 같이 음성 신호의 피치를 추정하는 함수로 널리 사용 하고 있다. 음성신호에서 fundamental frequency (F0)를 estimation하는 것은 매우 중요한 task이며 또한 상당한 어려움이 따른다는 것이 여러 연구들을 통해서 잘 알려진 사실이다. 본 논문에서는 AMDF 함수의 특성을 이용하여 개발한 두 가지의 알고리즘을 제시하였다. 첫째는 Local Minima에 Threshold 값을 적용하여 피치 주기를 측정 할 수 있는 nulls들을 찾아내는 알고리즘이고, 다음은 AMDF 함수와 ACF 함수 사이의 관계식을 응용한 알고리즘이다. 한국어의 감정 표현 언어들로 구성된 제시문을 널리 사용하고 있는 상용 기기로 녹음한 음성 신호를 본 논문이 제안한 알고리즘들에 적용하여서 시뮬레이션을 통해 음성 신호의 피치 주기를 측정하여서 그 성능을 알아보았다.

The modern play is going through a change that is differentiating it from the plays of yesterday. The importance of narration through language, specifically that of words spoken on stage as a means of communication is being replaced by images and minimalism of words. The narration that depended on spoken words today depends more on the images that are conjured on stage. This movement shows also the very development of stage and its craft in the domain of theater and especially holds true in the avant-garde theaters of today. The avant-garde theater, in trying to duplicate the reality does not confine itself to oratory rhetorics that we see in the traditional plays of the past but expresses itself by mimicking the reality to the utmost possible.

The purpose of this research is to analyzing the welfare function of the senior citizen with similar type of compounding the school facility, to analyze the problematical point of present condition. And also propose the spatial constitution which the student and the regional senior citizen are easy to utilize on the basis of the result. In a type of educational facility composition, it became clear that a ratio and the inflection order that elderly welfare facilities occupied of vacant class room were low. In other words, in composition of a school facilities, elderly welfare facilities can be said to be an important problem. As a result of having analyzed an existing compound facilities, there was limited interchange of student and a the aged. In addition, there were problems such as learning environment by an intersection of circulation. Therefore, composition of educational facility and elderly welfare facilities is not space composition that is intersection of simple specification function. In other words, a program of the common space which is necessary for the local community formation is necessary. Setting of semi-public area proposes the function of the existing facility and actual condition of spatial use in prerequisite.
