Utterance verification is used in variable vocabulary word recognition to reject the word that does not belong to in-vocabulary word or does not belong to correctly recognized word. Utterance verification is an important technology to design a user-friendly speech recognition system. We propose a new utterance verification algorithm for no-training utterance verification system based on the minimum verification error. First, using PBW (Phonetically Balanced Words) DB (445 words), we create no-training anti-phoneme models which include many PLUs(Phoneme Like Units), so anti-phoneme models have the minimum verification error. Then, for OOV (Out-Of-Vocabulary) rejection, the phoneme-based confidence measure which uses the likelihood between phoneme model (null hypothesis) and anti-phoneme model (alternative hypothesis) is normalized by null hypothesis, so the phoneme-based confidence measure tends to be more robust to OOV rejection. And, the word-based confidence measure which uses the phoneme-based confidence measure has been shown to provide improved detection of near-misses in speech recognition as well as better discrimination between in-vocabularys and OOVs. Using our proposed anti-model and confidence measure, we achieve significant performance improvement; CA (Correctly Accept for In-Vocabulary) is about 89％, and CR (Correctly Reject for OOV) is about 90％, improving about 15-21％ in ERR (Error Reduction Rate).

The minimum aberration criterion is commonly used for selecting good fractional factorial designs. In this paper we give same necessary conditions for $3^{n-k}$ fractional factorial designs. We obtain minimum aberration $3^{n-k}$ designs for k = 2 and any n. For k > 2, minimum aberration designs have not found yet. As an alternative, we select a design with minimum aberration among minimum-variance designs.

This paper aims to review Hammond's (1999) analysis of English word stress and propose an alternative by exploring two questions: Why English words display flexible stress patterns and what are the conditions all English words have to obey. As answers to the questions I propose an invisible suffix after words with final stress, foot structures with two levels, and four constraints, two of them are attained by revision of Hammond's. As long as words satisfy the constraints, more than one foot structures are allowed. That is why the English lexicon displays flexibility.

Objective : Osim((惡心) stands for nausea which usually precede vomiting(嘔吐). Although it is very common symptom, we can't find the word Osim in some ancient classics. So we tried to find when it had appeared, and what had been its substitute in former medical classics. Material and Methods : The digitalized text in Zhonghuayidian(中華醫典) was used for text search. The text search was performed chronologically. Results : We found that there had been yokto(欲吐), yokgu(欲嘔), geongu(乾嘔), beon(煩), beonsim (煩心), simbeon(心煩), min(悶), ongi(溫氣) as the precedent expression of osim(惡心), which had appeared in Jebyungwonhuron(諸病源候論, 610) for the first time. Conclusion : Until Tang dynasty, there had been kinds of alternative expressions correspond to osim(nausea).

In this Paper, we propose a keyword spotting system as an alternative to searching system for poor quality Korean document images and compare the Proposed system with an OCR-based document retrieval system. The system is composed of character segmentation, feature extraction for the query keyword, and word-to-word matching. In the character segmentation step, we propose an effective method to remove the connectivity between adjacent characters and a character segmentation method by making the variance of character widths minimum. In the query creation step, feature vector for the query is constructed by a combination of a character model by typeface. In the matching step, word-to-word matching is applied base on a character-to-character matching. We demonstrated that the proposed keyword spotting system is more efficient than the OCR-based one to search a keyword on the Korean document images, especially when the quality of documents is quite poor and point size is small.

This Study is divided into 5 separate Parts and an Abstract. Part Ⅰ, Ⅱ consist mostly of a collection of problems, current status, motives and the future of ADR. In Pert Ⅲ was described ADR as policies of judicial settlements. We must accept that a diversity of legal culture will always continue to exist. Accordingly we must learn to accommodate those differences of 'culture' around us and to harmonize conflicting laws. This recognition of our reality should in no way be confused with pessimism. In fact if one accepts this perspective of the world ,the study of law seems enriched and becomes academically more challenging. Recently, in the United States, interest in alternative settlement mechanism has increased greatly, which leads me to wonder why such a phenomenon has taken place. In the first place, I'm amazed at the extent to which conciliation or mediation-or the new word, I guess, is alternative dispute resolution, which by now has its own acronym, "A.D.R,"-have gained attention here recently. When 35 years ago, there was virtually no interest in conciliation in this country at the time. What interest there was, was no in the law schools. But looking at the situation now, we have a spate of publications on the subject; we have organizations that are established for no other reason than to promote alternative dispute settlement. We have courses in the law schools. The American Association of Law Schools and the American Bar Association also have active programs. So we have to ask ourselves why. The difference between now and 35 years are striking. On the other hand, I think the interest of the public in ADR has probably been greatly enhanced by the politics of the so-called "poverty programs." I think that many of these assistance programs for the poor-and I do think the "poor" have become a rather expansive political movement beyond simply taking care of the most marginal people of society-have generated money to explore this kind of dispute resolution.

This study deals with the problem of transition from arithmetic to algebra and the relationship between elementary and secondary school mathematics for systems of linear equations. In elementary school, activity for solving word problems related to systems of linear equations in two variables falls broadly into using two strategies: Guess and check and making a table. In secondary school, those problems are solved algebraically, for example, by solving systems of equations using the technique of elimination. The analysis of mathematics textbooks shows that there is no link between strategies of elementary school mathematics and secondary school mathematics. We devised an alternative way to reinforce link between elementary and secondary school mathematics for systems of linear equations. Drawing a diagram can be introduced as a strategy solving word problems related to systems of linear equations in two variables in elementary school. Moreover it is closely related to the idea of the technique of elimination of secondary school mathematics. It may be a critical juncture of elementary-secondary school mathematics in the case of systems of linear equations in two variables.

Due to the social distancing in the Corona era, people are looking for an alternative online. As 'eXtended Reality' including various technologies, AR, VR and so on, is also on the rise, and the 'MZ' generation is growing to a new consumer group, the Meta-Verse is again in the spotlight. However, existing studies related to the Meta-Verse were mostly listing fragments of definition and classification or focused on eXtended Reality technologies and a subordinate concept. Hence, this study wold like to conduct an empirical analysis to verify influences of Metaverse's characteristic factors over word-of-mouth intention through flow and satisfaction.

The objective of this paper is to investigate the development of Silhak as a Korean epistemology, to investigate the implications of Silhak in Korean society, and to discover further environmental implications. The main discussion of this paper concerns with the epistemology of environmental philosophy. Epistemology is based on the justification of certain knowledge and social philosophy. Epistemology, from the Greek words episteme (knowledge) and logos (word/ speech) is the branch of philosophy concerned with theories of the sources, nature, and limits of knowledge. Since the seventeenth century, epistemology has been one of the fundamental themes of philosophers, who were necessarily obliged to coordinate the theory of knowledge with the development of scientific thought. It is a general belief that Western ideology is substantially embedded in Eastern ideology due to physical and metaphysical colonial involvement. We argue that ecological crisis may be resulted from western epistemological mechanical view, thus we suggests a Korean epistemology as an alternative. In this paper, we seek possibility of epistemological alternative of nature in the Korean traditional epistemology incorporating the epistemology of Sung confucianism and The Silhak.

Speech evaluation and treatment planning for the patients with articulation disorders have traditionally been based on perceptual judgement by speech pathologists. Recently, various computerized speech analysis systems have been developed and commonly used in clinical settings to obtain the objective and quantitative data and specific treatment strategies. 10 dysarthric children (6 neurogenic and 4 functional dysarthria) participated in this experiment. Speech evaluation of dysarthria was performed in two ways; first, the acoustic analysis by Visi-Pitch and a Computerized Speech Lab and second, the perceptual scoring of phonetic errors rates in 100 word test. The results of the initial evaluation served as primary guidlines for the indivisualized treatment planning of each patient's speech problems. After mean treatment period of 5 months, the follow-up data of both dysarthric groups showed increased maximum phonation time, increased alternative motion rate and decreased occurrence of articulatory deviation. The changes of acoustic data and therapeutic effects were more prominent in children with dysarthria due to neurologic causes than with functional dysarthria. Three cases including their pre- and post treatment data were illustrated in detail.
