Thyroplasty type III provides an effective mean of shortening the vocal fold. It is used primarily fer lowering vocal pitch. The indications for this surgery are the male patients with too high a vocal pitch of long duration which has proven resistant to voice therapy and a type of dysphonia characterized by high pitch and a breathy voice, in which the laryngeal findings include a very narrow glottal chink and a small amplitude of vibration, suggesting a stiff vocal cord. In this study, we have experienced two cases of high pitched voice, one is mutational falsetto and other is high pitched, breathy voice with stiff vocal fold. The results were satisfactorily successful with type III thyroplasty. So we report the cases of type III thyroplasty in patients of dysphonia with high pitched voice.

발성기구의 생리학적 연구나 발성장애의 병태를 검사함에 있어서 폐로부터 송출되는 호기의 에너지가 성문에 있어서 어느 정도로 목소리의 음원으로 변환되는 지를 아는 것은 대단히 중요하다. 이것을 알기 위해서는 발성시의 호기류율과 함께 성문하에 있어서의 호기압을 측정하여 발성된 목소리의 강도와의 관계를 조사할 필요가 있다. 기류 저지법을 이용한 발성시의 공기역학적 검사법은 발성장애에 대한 공기역학적 검사의 한 방법으로, 기류 저지법을 사용한 발성시의 호기압(폐내압)측정을 호기류율, 목소리 강도, 높이의 측정과 조합시키는 방법으로 장치는 기류저지용의 회전 셧터를 발성기능 검사장치의 mouth piece에 접촉시킨 것이다.

본 연구에서는 글이해시의 참조관계 처리과정에서 맥락이 어떤 역할을 하며 다른 통사단서와는 어떤 관계를 갖는지를 대명사 해결을 중심으로 조사했다. 실험 1에서는 대용어 문장의 국소적 맥락에 의한 촉진효과가 관찰되었다. 그러나 맥락과 통사단서간의 상호작용으로 맥락 촉진효과는 통사적 명료조건에서보다는 애매조건에서 더 강하게 나타났다. 실험 2에서는 국소적 맥락정보가 없더라도 선행글의 전체주제적 맥락정보가 촉진제 역할을 하는 것으로 밝혀졌다. 또한 전체주의적 맥락이 주어지는 경우 글의 표면구조적 특성에 따른 위치효과가 나타나지 않았다. 즉 두 개의 실험을 통해 대명사 해결에 미치는 통사단서의 효과가 일부 지지되었으며, 특히 맥락효과는 국소적, 총체적 수준에서 모두 일관되게 입증되었다.

개체명 인식은 입력 문장에서 인명, 지명, 기관명, 날짜, 시간과 같이 고유한 의미를 갖는 단어들을 찾아 개체명을 부착하는 기술이다. 최근 개체명 인식기는 형태소 단위나 음절 단위의 입력을 사용하는 연구가 주로 진행되고 있다. 그러나 형태소 단위 개체명 인식은 미등록어를 처리하지 못하는 문제점이 존재하고 음절 단위 개체명 인식은 단어의 의미를 제대로 반영하지 못하는 문제점이 존재한다. 본 논문에서는 이 문제점을 보완하기 위해 품사 정보를 활용한 음절 단위 개체명 인식기를 제안한다. 또한 개체명 인식 성능에 큰 영향을 미치는 개체명 사전 자질을 더 효과적으로 사용할 수 있는 방법을 제안하며 이 방법을 사용했을 때 기존의 방법보다 향상된 개체명 인식 성능(F1-score 0.8576)을 보였다.

개체명 인식 연구에서 우수한 성능을 보이고 있는 bi-LSTM-CRFs 모델은 처리 속도가 느린 단점이 있고, CNN-CRFs 모델은 한국어 말뭉치를 사용하여 제대로 분석되지 않았다. 본 논문에서는 한국어 개체명 인식 말뭉치를 이용한 CNN-CRFs 모델의 음절 단위 한국어 개체명 인식 방법을 제안한다. 실험 결과 bi-LSTM-CRFs 모델보다 CNN-CRFs 모델의 F1 score가 0.4% 높았고, 27.5% 빠른 처리 속도를 보였다.

This study aims to look at main problems of visiting the clinic, diagnoses and other related factors of outpatients in a private psychiatric clinic f3r children and adolescents located in Seoul. The analyses were based on the reports of 2,785 patients who were 18 years old and less, and visited the clinic during last 4 years. The results showed that the ratio of boys to girls was 2.7 to 1, and about 64% of the whole sample were 6 years old and less. Especially the percentage of patients aged 3 and less was the highest and that of schoolage and more was gradually reduced. The average number of siblings was 195 and the percentage of the first child in a family was the highest. Particularly, there were more boys in rase of one child families and more girls in case of families with 3 children and more. The chief problems were mainly language-deficit, hyperactivity, autistic behaviour, tic, aggressive behavior and academic problem. The higher frequency of diagnoses was in the order of parent-child problem, mental retardation, developmental language disorder, reactive attachment disorder, other emotional disorder, and pervasive developmental disorder. The more frequently used method fir treatments was in the sequence of psychotherapy, play therapy, parental counseling, occupational therapy and speech therapy. The results from this study were compared with those from other studies and discussed.

This paper discusses English Hedges or Hedging Expressions on the basis of their morphosyntactic-pragramatic properties within the perspective of sociolinguistics. The term, 'Hedges' for the past decades since Lakoff(1973), has received little attention from the English grammar circles such as morphosyntax and the generative grammar theories. This paper presents a more comprehensive approach to the identification, distributions, functions, and the morphosyntactic properties of English Hedges. The earlier research on English Hedges in the 70's show that hedges are metalinguistic or mitadiscourse expressions which constitute a means for executing Politeness strategy in pragmatics. Nonetheless, research from the interface of syntactic-pragmatics has been scarce. This article suggests a more complex body of English hedges that have not been extensively discussed in the literature. Additionally, their configurational domain is to be proposed as part of the PolP with [±hedged] above CP⁺ (or CP beyond). The ramifications of the current study are suggested in terms of comparative linguistics, EFL/ESL studies of English for global communication, and pragmatics-sensitive machine translation studies in the forseeable future.

This study is focused on the examination of changes in textbooks of Home Economics in High school from 7^st to 2015 curriculum, especially the 'Food and Nutrition section. We investigated the content elements of the National Curriculum Guide, the changes in learning contents, and the number of pages of Food and Nutrition section. The key words were extracted and the connective relationships between words were visualized using a method of language network analysis through word cloud and Semantic Network Analysis. According to the results of the research, the portion of the Food and Nutrition section has been gradually decreased on the Technology·Home Economics, following the development of the curriculum. Through the whole curriculum, 'invitation', 'Korean food', 'baby·nutrition' are appeared as key words. The education contents of Food and Nutrition section from the 7^th to 2015 revised have been developed and advanced with the changes of social needs. However, the reduction of portion and insufficiency of content elements of Food and Nutrition section bring concerns toward the decline of the quality of education on dietary life.

This study was designed to find the characteristics of mathematical errors and discourse in simultaneous equations and inequalities for migrant students from North Korea. 5 sample students participated, who attended in an alternative school for the migrant students from North Korea at the study in Seoul, Korea. A total of 8 lesson units were performed as an extra curriculum activity once a week during the 1st semester, 2011. The results indicated that students showed technical errors, encoding errors, misunderstood symbols, misinterpreted language, and misunderstood Chines characters of Koreans and the discourse levels improved from the zero level to the third level, but the scenes of the third level did not constantly happen. Nevertheless, the components of discourse, explanation & justification, were activated and as a result, evaluation & elaboration increased in ERE pattern on communication.

Background and Objectives Proton pump inhibitors (PPIs), mucolytics, and steroids were commonly recommended after phonomicrosurgery to prevent worsening of vocal fold (VF) scar formation and subglottal swelling. However, there is no consensus about whether laryngeal reflux and thick discharge are associated with the voice outcomes following phonomicrosurgery in benign VF lesions. The purpose of this study is to examine voice outcomes of use of PPIs, mucolytics,and steroids after phonomicrosurgery. Materials and Method This randomized controlled study is performed with patients undergoing laryngomicroscopic surgery for VF polyp and cyst. Participants were randomly assigned to 1) no medication, 2) PPIs, 3) PPIs+mucolytics, and 4) PPIs+mucolytics+steroids for 2 months postoperatively. Grade, roughness, breathiness, asthenia, and strain (GRBAS) scale, stroboscopic examination, aerodynamic assessment, acoustic analysis, and Voice Handicap Index-10 (VHI-10) were performed pre- and post-operatively at 2 months. Parameters were compared among four groups. Results Among 85 patients, a total of 50 patients were included. The VHI-10, perceptual and acoustic parameters improved in all groups after surgery. However, there was no significant difference in those parameters among all groups. Conclusion PPIs, mucolytics, and steroids did not significantly influence voice outcomes after phonomicrosurgery in patients with benign VF lesions.
