Background and Objective The purpose of this study is to report the effect of voice therapy using the voice reinforcement method (VRM) in patients with vocal nodules. It is one of the holistic voice therapy methods for improving vocal mechanisms. VRM includes not only direct and indirect voice therapy, but also trial therapy and self-practice. Composed of four stages: vocal hygiene education, relaxation, reinforcement, and generalization. Materials and Methods The subjects were 13 patients who were diagnosed with vocal nodules. Acoustic analysis, auditory perceptual assessment, K-VHI-10 and nodules size were compared before and after voice therapy. Voice therapy was conducted by speech-language pathologist and the mean number was 4.2. Results In acoustic analysis, Jitter, vF₀, vAm, Shimmer, NHR, and VTI were significantly decreased. F₀ was increased after voice therapy for women. 'Grade', 'Rough,' and 'Breathy' were significantly decreased in the GRBAS scale after voice therapy. In addition, K-VHI-10 and nodules size were significantly decreased. Conclusion VRM seems to be an effective voice therapy method in vocal nodules treatment. In VRM, especially, trial therapy is given motivation for vocal nodules treatments and self-practice has a continuous therapeutic effect in everyday life. VRM can be also applied to the voice therapy for other hyper-functional dysphonia.

Vocal hyperfunction is considered to be the most significant characteristic in larynx disorders which is found among many patients presenting hoarseness Primarily as chief complaint. In Pusan National University Hospital, we executed the voice therapy to 28 patients being 17 female and 11 male patients who visited the Voice ＆ Speech Therapy Clinic, due to the voice disorder, and then compared and analysed the voice before and after its therapy using acoustic and aerodynamic test. The obtained results were as follows. In the analysis by the local findings, it was improved to 88% in the patients of vocal nodule, 75% in mutational falsetto, 75% in the functional dysphonia, 75% in the vocal cord palsy, 50% in the vocal polyp and 50% in dysphonia plica ventricularis. For the acoustic analysis, Fo, litter, Shimmer and NHR were measured. In the patients of mutational falsetto, Fo, Jitter and NHR were shown to be improved significantly and in the patients of vocal nodule, Shimmer was shown to be improved significantly. In the patients of vocal polyp, Fo was significantly improved. In the patients of vocal cord palsy in litter and NHH were significantly improved. In the patients of dysphonia plica ventricularis, Shimmer and NHR were significantly improved and the patients of functional dysphonia were more improved in Fo, litter and Shimmer. For the aerodynamic analysis, MPT was measured. In particular, it was shown to be improved significantly in the patients of vocal nodule, improved in the vocal polyp, vocal cord palsy, functional dysphonia patients.

Purpose: The aim of the study was to develop a Korean version of an ICF e-Learning tool (KICF e-Learning tool). Methods: The process of translation and adaptation of the ICF e-Learning tool was followed: two translators developed the Korean versions independently, and a consensus version of the translation was then produced. An expert committee, which was composed of five experts from physiotherapy, occupational therapy, speech pathology, and social welfare, reviewed the consensus Korean version to make a beta version of the tool. A field test was conducted to determine if the Korean version of the tool was easy to understand and suitable to use in ICF learning. Feedback from the field test were used for the final adaptation of the KICF e-Learning tool. Results: One-hundred and twenty-six volunteers (40 males and 76 females) were invited to examine the KICF e-Learning tool. The participants reported various levels of ICF knowledge from none to very good. Forty-eight participants reported no knowledge of ICF. The majority of participants (n=84) reported that Korean terms or expression in the tool were easy to understand and one-hundred fourteen participants would recommend the tool to another person. The Korean cases would be helpful for a Korean audience to study the ICF using the tool. Conclusion: The KICF e-Learning tool was developed and is ready for use by the public for the consistency of ICF education. On the other hand, development of an advanced module will be needed.

Chronic mental-handicapped people are lacking in non-verbal expression such as eye contact, intonation, voice volume, facial expression, and gesture as well as the contents of speech, speak with a monotonous voice, fail to be vivid and clear in voice, and have absence of expression, thereby bringing about difficulty even for social adjustment and about low self-esteem. Accordingly, the purpose of this study was to examine effectiveness for enhancing self-expression and self-esteem by applying music therapy to the chronic mental-handicapped. The subjects were the chronic mental-handicapped who receive rehabilitation service at the community rehabilitation center, and who have over 10 years in the duration of disease. 1he music therapy activity was progressed with totally 14 sessions during 7 weeks with twice a week. This study confirmed t-test that is verification of difference in the mean, in order to examine difference between before and after music therapy in self-expression and self-esteem of the chronic mental-handicapped, and researched into qualitative case. The findings are as follows. First, as a result of score in self-expression scale, the significant improvement was shown after music therapy compared to before music therapy. The significant difference was indicated in verbal self-expression, phonetic self-expression, and non-verbal self-expression, which are its sub-spheres. Thus, the conclusion was obtained as saying that music therapy is effective for enhancing self-expression. Second, as a result of score in self-esteem scale, the significant difference was shown after music therapy compared to before music therapy. Thus, the conclusion was obtained as saying that music therapy is effective for enhancing self-esteem. Through the above results, the music therapy showed effectiveness of self-expression ability and self-esteem in the chronic mental-handicapped at the community rehabilitation center, thereby having been confirmed to be possibly utilized as rehabilitation program for the social skill ability and the social adjustment of the chronic mental-handicapped.

The purpose of this study was to establish preliminary data on the speech rates in groups of normal speaking adults and children. The results of the present study are intended to serve as clinical measurement guidelines for diagnosis, assessment, treatment planning, and therapy progresses of stuttering. Thirty-one adults (16 females, 15 males), aged 18-30 years and thirty normally developing children (15 females, 15 males), aged 8-10, participated in the study. The subjects' reading of the Stroll (Jeong, 1994) passage and l-minute portion of talking about the daily routine were sampled. The adult speakers had rates of $308.29\pm22.57$ syllables per minute (SPM) or $108.06\pm6.17$ words per minute (WPM) during reading, and $252.87\pm40.86$ SPM and $92.26\pm17.12$ WPM during talking. The children had rates of $176.67\pm33.65$ SPM or $64.07\pm12.62$ WPM during reading, and $149.30\pm33.14$ SPM and $56.60\pm11.36$ WPM during talking. The results of t-tests for reading and talking tasks in adults showed that SPM in reading (t=2.211, p< .05) and WPM in talking (t=-2.284, p< .05) differed significantly by the gender. To answer the questions whether the rate is different across children' s gender and age, a two-way ANOVA was performed. Both SPM and WPM in reading tasks were significantly different between groups of children aged 8 and 10 (p< 01), In speaking tasks, both SPM and WPM were significantly different between groups of children aged 8 and 10, and between 9 and 10.

The purpose of this study was to investigate the effects postural changes on respiratory muscles and acoustic parameters of the children with spastic cerebral palsy. Nine children with spastic cerebral palsy who required assistance when walking were selected. The ages of the children ranged from 6 to 9 years old. The phonation of the sustained vowel /a/ and the voice qualities of each child such as fundamental frequency($F_0$; Hz), pitch variation (Jitter; %), amplitude variation (Shimmer; %) and noise to harmonic ratio (NHR) were analyzed by Multi-Dimensional Voice Program (MDVP). The muscle activity of three major respiratory muscles: pectoralis major muscle, upper trapezius muscle and rectus abdorminalis muscle, were measured by examining the root mean square (RMS) of the surface EMG to investigate the impact of changes in the adjusted sitting posture of each subject. However, the RMS of pectoralis major muscle showed a significant differences (p<.05). Secondly, there were no significant differences in $F_0$, Jitter and Shimmer between pre and post posture change, but there was a significant difference in NHR (p<.05). The data were collected in each individual; once prior and once after the sitting posture change. The data were analyzed by Wilcoxon signed ranks-test using SPSS version 14.0 for Windows. The findings of this study were as follows; Firstly, the RMS of upper trapezius and rectus abdorminalis muscle were not significant different between pre and post sitting posture changes. From the result, it is concluded that changes in the adjusted sitting posture decreases the abnormal respiratory patterns in the children with spastic cerebral palsy which is characterized by the hyperactivity of the respiratory muscles in breathing. Also, there is increased on the voice qualities in children with spastic cerebral palsy.
