본 논문에서는 실시간으로 운율을 제어 할 수 있는 방법의 하나인 지속시간 변경을 주파수 영역에서 변경하는 방법을 사용하였다. 또한 프레임처리에서 윈도우의 영향으로 스펙트럼 왜곡 및 음질 저하를 방지하기 위하여 보상된 윈도우를 적용하였다. 만약 운율조절에 있어서 지속시간을 자유롭게 변경할 수 있다면 언어장애인의 발음교정이나 어학학습 등 여러 분야에 이용할 수 있을 것이다. 결과적으로 본 논문에서 제안한 FFT변환 특성을 이용하여 지속시간을 변경한 방법을 사용하여 피치변경후에 지속시간까지 변경한 음성의 명료도가 피치만 변경한 경우보다는 떨어지지만 자연성 면에서는 더 좋은 결과를 얻을 수 있었다.

this paper is to propose the formative Korean accentuation rule for the korean tort to speech conversion. The accentuation rule is as following： (1) If the rhyme of first syllable is -v, then accent is on the next syllable. (2) If the rhyme of first syllable is not -v, then accent is on the first syllable.

자바에서 또한 이러한 병행성 프로그램을 지원하기 위한 다양한 언어적 지원과 병행적인 요건을 지원하고 있다. Thread class지원, Synchronized 예약어, 상호협동 관계를 표현하기위한 wait(), notify(), notifyAll() 메서드 , monitor 메커니즘등을 지원하고 있다. 하지만 이는 아주 저 수준의 지원형태이며 여러 가지 문제점을 야기할 수 있다. 이에 대해 병행적 이론의 정수라고 할 수 있는 pi-calculus의 이론과 기법을 도입하여 새로운 시각으로 병행성 프로그래밍에 대한 접근을 하고자 한다. 여기에 실용적으로 많이 사용되고 발전되어온 자바에서 적용하고자 한다. pi-calculus에 기반한 pict를 모델로 하여 pict에서 지원하는 아주 명료한 연산자와 current object를 도입함으로써 보다 표현력과 확장성, 검증성이 뛰어난 고 수준 자바 라이브러리를 설계하고자 한다.

Word problems can lead learners to more meaningfully learn mathematics by providing learners with various problem-solving experiences and guiding them to apply mathematical knowledge to the context. This study attempted to provide implications for the textbook writing and teaching and learning process by examining the word problem of elementary mathematics textbooks from the perspective of practical context. The word problem of elementary mathematics textbooks was examined, and elementary mathematics textbooks in the United States and Finland were referenced to find specific alternatives. As a result, when setting an unnatural context or subject to the word problem in elementary mathematics textbooks, artificial numbers were inserted or verbal expressions and illustrations were presented unclearly. In this case, it may be difficult for learners to recognize the context of the word problem as separate from real life or to solve the problem by understanding the content required by the word problem. In the future, it is necessary to organize various types of word problems in practical contexts, such as setting up situations in consideration of learners in textbooks, actively using illustrations and diagrams, and organizing verbal expressions and illustrations more clearly.

Since there are differences in the content, structure and functions of interpersonal communication during the practice of school science classes, it needs to articulate the difference of the modality of pedagogical practice in order to understand science teaching in detail. These characteristics of science teaching can be investigated by further insightful analysis on language in the science classroom. In this study, classroom discourse language codes using Bernstein's code theory were analyzed in the case of a middle school science class on the unit of minerals. The discourse language code was identified by the value of classification, which revealed power relations to the contexts of discourse and participants of discourse. It was also identified by the value of framing, which showed hierarchical relation between teacher and students as discourse subjects, and discursive control on the initiative of discourse. The results addressed that six types of discourse language codes were constructed and that those language codes reflected diverse modalities of science teaching from student-centered instruction to teacher-centered instruction in relation to classroom discourse. The modality of science teaching according to the transition tendencies of discourse language code showed dynamic variations of 'controlled student-centeredness inducing teaching' - 'positional student-centeredness permissive teaching' - 'controlled students' participation permissive teaching' - 'controlled student-centeredness facilitative teaching' - 'student-centeredness enhancing teaching'. In addition, results released that discursively and hierarchically weak control of discourse is necessary for enhancing student-centeredness of science teaching. Moreover, teaching practice enhancing student-centeredness can be accomplished by the harmony of a teacher's perception of discourse language code and his/her orientation to constructivist teaching and student-centered teaching.

In line with the development of Media, the use of character has been developed in various ways. Specially, it has been emerged the functions of written language of visualization and delivery of emotion in the digitalized environment due to speedy growth of internet and Mobile. The emoticons emerged as a tool for the convenience of communication proved to have taken effective role in the part of communication culture. Particularly, Hangul emoticons which contains the meaning of communication and sharing in tandem with the principle of Hangul invention, provides convenience in combination & use due to its structural and design characteristic for which it plays a significant role of visual element. Hangul emoticon is definitely a part of Hangul culture and in view of globalization of visual language in connection with media development, there is a huge potential being to be used as a international communication tool. In this study, it will be reviewed on the increased utilization of Hangul emoticons and related public issues as being a part of typography media, in view of the generalization of private media as well as change of subjective user.

Recently, it is more important to do part of software designers for developing user-centered software. They produce visual document for helping communication between developers and visual diagram for analyzing user need factors based on user scenario. Case study of architecture real dispatch service can show developing samples. It is important to produce visual document for one combined opinion between developers in process of defining of development boundary, main concept development, selecting of development system. And visual document process with visual language by software designer is step for recognizing of user need factors before developing interface design in process of collecting design factors of user and environment and analyzing design factor by user scenario. Also, in process of interface and prototype development, it need visual document for peaceful and concord process between developers. Those visual documents with visual language could help to define developers role and duty, user-centered concept development and various interface development proposal during software developing.

The aim of this paper is to clarify the difference between the concept of deduction-induction and Aristotle's concept of syllogismos-epagoge. First, Aristotle does not use the expression 'invalid syllogismos'. But a valid deduction is distinguished from a invalid deduction in modern logic. Second, from Aristotle's point of view syllogismos is paralleled by epagoge. Because syllogismos is equivalent to epagoge in logical form. But a disturbing lack of parallelism exists between deduction and induction by which the standards for establishing inductive conclusions are more demanding than those for deductive ones. Third, instructors in introductory logic courses ordinarily stress the need to evaluate arguments first in terms of the strength of the conclusion relative to the premises. Accordingly, students may be told to assume that premises are true. But Aristotle does not assume that premises are true. A syllogismos start from the conceptually true premise and a epagoge start from the empirically true premise.

This study investigated the factors influencing the perceptions that military officers can harbor regarding persons who stutter in terms of how well they can adapt to the army. In total, 89 participants were randomly assigned to each of the three different conditions ("fluent speech"=23, "mildly stuttered speech"=34, and "severely stuttered speech"=32). Subsequently, the participants were asked to listen and rate each sample in terms of "the speaker's communicative functioning (i.e., speech fluency, intelligibility, naturalness, speech rate), personal traits (i.e., likeability, anxiety level, intellectual level, and sociability), and the perceived degree of the adaptability to the army." The results showed that significant differences were found between "fluent speech" and "severely stuttered speech" in the perceived communicative functionings and the perceived adaptability to the army. Moreover, there were significant differences in the same variables between "mildly stuttered speech" and "severely stuttered speech." However, there were no significant differences between "mildly stuttered speech" and "fluent speech." Following the conducting of the Pearson correlation test, strong correlations were also found between the perceived communicative functionings, in particular "speech fluency," and the perceived adaptability to the army. Those results can be employed to argue that the communicative functionings can serve as factors which influence the perceptions of persons who stutter in terms of how well they can adapt to the army. Further discussion has taken place regarding the relationship between the perceived communicative functionings and the perceived adaptability to the army.

Background and Objectives : The purpose of this study was to examine objectively pre and post operative voice quality evaluation and intelligibility of alaryngeal voice using speech recognition program, HUVOIS. Materials and Methods : 2 laryngologists and 1 speech pathologist were evaluated 'G', 'R', 'B' in the GRBAS sclae and speech intelligibility using NTID rating scale from standard paragraph. And also acoustic estimates such as jitter, shimmer, HNR were obtained from Lx Speech Studio. Results : Speech recognition rate was not significantly different between pre and post operation for pathological vocie samples though voice quality(G, B) and acoustic values(Jitter, HNR) were significantly improved after post operation. In Alaryngeal voices, reed type electrolarynx 'Moksori' was the highest both speech intelligibility and speech recognition rate, whereas esophageal speech was the lowest. Coefficient correlation of speech intelligibility and speech recognition rate was found in alaryngeal voices, but not in pathological voices. Conclusion : Current study was not proved speech recognition program, HUVOIS during telephone program was not objective and efficient method for assisting subjective GRBAS scale.
