Post-thyroidectomy syndrome refers to various voice changes experienced after the thyroid surgery. Among them, surgery or injection therapy has been prioritized over voice therapy for the bilateral vocal cord paralysis. However, if it is possible to determine whether voice therapy can be applied first, a faster treatment recovery will be possible. In this study, voice therapy was performed on a 59-year-old female patient with bilateral vocal cord paralysis after total thyroidectomy. This study is to presents the criteria for applying the voice therapy first for bilateral vocal folds paralysis and to share successful voice therapy sessions.

위식도 역류 질환의 전형적인 증상에 반하여 인후두에서 나타나는 애성, 만성 기침, 헛기침, 인후두 이물감등의 비전형적인 증상에 대해 최근 관심이 높아지고 있다. 특히 애성이 주된 증상으로 나타나는 경우 일부에서 후두 후방에 점막의 비후 소견이나 육아종을 보이기도 하지만 많은 경우 후두내 기질적 병변을 찾기 어려울 때가 많으므로 의식도 역류 질환과 연관된 애성으로 진단하기 위해서는 자세한 병력 파악 및 이학적 검진, 그리고 위식도 역류 진단을 위한 검사 둥이 요구된다. 저자들은 인후두 이물감을 주소로 내원하여 위식도 역류 검사상 위식도 역류 질환으로 판명되었던 환자 중 애성이 동반된 환자 20례에 대하여 치료전 음성 검사를 시행하였으며 일반적인 치료 후 8주째 추적 검사를 시행하여 그 결과를 문헌 고찰과 함께 보고하고자 한다.

Purpose : To evaluate the voices of irradiated patients with early glottic carcinoma and to compare these with the voices of healthy volunteers. Materials and Methods : The voice samples (sustained vowel) of seventeen male patients who had been irradiated for T1a glottic squamous carcinoma at least 1 year prior to the study were analyzed with objective voice analyzer (acoustic voice analysis, aerodynamic test, and videostroboscopic analysis) and compared with those of a normal group of twenty age- and sex-matched volunteers. Average fundamental frequency, jitter, shimmer, and noise-to-harmonic ratio were obtained for acoustic voice analysis. Maximal phonation time, mean flow rate, intensity, subglottic pressure, glottal resistance, glottal efficiency, and glottal power were obtained for aerodynamic test. Results : The irradiated group presented higher values of shimmer in acoustic voice analysis. There was no significant difference between two groups in other parameters. Conclusion : In this study all the objective voice parameters except shimmer were no4 significantly different between the irradiated group and the control group. These results suggest that the voice quality is minimally affected by radiation therapy for 71 a glottic carcinoma.

A cat robot for the Autism Spectrum Disorders(ASD) treatment was designed and conducted field test. The designed robot had emotion expressing action through interaction by the touch, and performed a reasonable emotional expression based on Artificial Neural Network(ANN). However these operations were difficult to use in the various healing activities. In this paper, we describe a motion design that can be used in a variety of contexts and flexibly reaction with various kinds of situations. As a necessary element, the speech recognition system using the speech data collection method and ANN was suggested and the classification results were analyzed after experiment. This ANN will be improved through collecting various voice data to raise the accuracy in the future and checked the effectiveness through field test.

1996년 10월부터 1997년 6월까지 안ㆍ이비인후과병원과 영동세브란스병원 이비인후과에 음성장애를 주소로 내원한 환자 중 성대양성질환으로 성대미세수술을 시행하고 음성검사를 시행한 환자들을 대상으로 하였다. 대상환자는 총 85명으로 후향적으로 의무기록을 검토하여 수술시 병명, 수술시 레이저(laser)사용유무, 수술 후 발성장애 유무를 확인하였으며 그 중 수술 후 지속적인 혹은 반복적인 발성장애를 보인 환자는 총 12명으로 발성장애의 원인과 치료의 종류 및 치료효과를 판정하기 위해 후두비디오스트로보 스코피 검사, 청각심리검사 및 음성분석을 확인하였으며 통계처리를 하였다.

전체 성대 마비 환자의 약 10%에서 발생하는 것으로 알려진 양측 성대 마비는 안정 혹은 경미한 운동시에도 호흡 장애를 초래하는 경우라면 이에 대한 치료가 요구되는 질환이다. 이에 대한 치료 방법으로는 성문 기도를 넓히면서 흡인이 되지 않고 음성장애를 일으키지 않는데 목적을 두고 피열연골 고정술, 피열연골 절제술, CO2, 레저 피열연골 절제술, 성대 측방 고정술, 후성대 절제술, 점막하 성대 절제술, 근-신경식술 등 다양한 방법이 사용되어져 왔다. (중략)

Background and Objectives : Patients with so-called 'functional voice disorders' who have structurally normal larynges and demonstrate muscle misuse in the larynx, and those with several interacting causes including habitual muscle tension, are probably better defined as having a 'muscle misuse voice disorder'. The purpose of this study was to analyze the voice and effectiveness of voice therapy in patients with functional voice disorders and to provide a guide for the treatment of functional voice disorder. Materials and Method : The records of 35 patients, presenting with functional voice disorder and receiving voice therapy during October, 2001 to September, 2002, were reviewed. Prior to voice therapy, the stroboscopic examination of their larynx, aerodynamic and acoustic analysis was done. The results of voice therapy were compared according to the patient's subjective, perceptual evaluation of voice, and maximal phonation time. Results : Patient's subjective, perceptual evaluation, and maximal phonation time showed superior results after voice therapy. Conclusion : The result of this study indicates that voice therapy is an effective treatment method of patients with functional voice disorder, especially muscular tension dysphonia.

In addition to administering a questionnaire (J-survey), which questions individuals on subjective vocal fatigue, voice samples were collected before and after speech-language pathology sessions from 50 female speech-language pathologists in their 20s and 30s in the Daejeon and Chungnam areas. We identified significant differences in Korean Vocal Fatigue Index scores between the fatigue and non-fatigue groups, with the most prominent differences in sections one and two. Regarding acoustic phonetic characteristics, both groups showed a pattern in which low-frequency band energy was relatively low, and high-frequency band energy was increased after the treatment sessions. This trend was well reflected in the low-to-high ratio of vowels, slope LTAS, energy in the third formant, and energy in the 4,000-8,000 Hz range. A difference between the groups was observed only in the vowel energy of the low-frequency band (0-4,000 Hz) before treatment, with the non-fatigue group having a higher value than the fatigue group. This characteristic could be interpreted as a result of voice abuse and higher muscle tonus caused by long-term voice work. The perturbation parameter and shimmer local was lowered in the non-fatigue group after treatment, and the noise-to-harmonics ratio (NHR) was lowered in both groups following treatment. The decrease in NHR and the fall of shimmer local could be attributed to vocal cord hypertension, but it could be concluded that the effective voice use of speech-language pathologists also contributed to this effect, especially in the non-fatigue group. In the case of the non-fatigue group, the rhamonics-to-noise ratio increased significantly after treatment, indicating that the harmonic structure was more stable after treatment.

Background : This study aimed to estimate the clinical outcome and identify the characteristics of a group of patients with pulmonary tuberculosis who completed anti-tuberculosis therapy with the First-line drugs in spite of having positive smear results with negative sputum culture results over the previous six months. Method : A retrospective chart review of 21 patients who fulfilled the above criteria between 1995 and 1999 was performed. The laboratory data as well as the clinical data of the patients with positive smear results and negative culture results over a six months period were reviewed. Results : The negative conversion of sputum culture results was achieved within $1.3{\pm}1.2$ months and the negative conversion of the sputum smear results was accomplished during $9.5{\pm}3.3$ months. Chest X-rays at 5 months following the institution of anti-tuberculosis therapy from all patients revealed improvements. Four out of 21 patients(19%) relapsed during the follow up, $15.2{\pm}13.4$ months after administering anti-tuberculosis therapy for $13.3{\pm}3.1$ months. Relapses were confirmed from between 3 months and 4 months after the treatment completion. Only one of the four relapses had no past history of anti-tuberculosis therapy and the others had prior treatment twice (p<0.01). The period of anti-tuberculosis treatment was extended to a mean of $4.6{\pm}2.6$ months in 12 patients. However, prolongation of anti-tuberculosis therapy had no affect on the relapse rate (odds ratio, 95% CI 0.18, 2.15). Conclusion : Prolongation of therapy with the First-line drugs is not necessary for patients with persistently positive smear results over 6 months and negative culture results. A patient who has had prior anti-tuberculosis therapy more than twice should be paid the closest attention.
