Mutational falsetto is a kind of voice disorders due to the failure to acquire proper low-pitched voice during the puberty. The patients with mutational falsetto can produce the normal low-pitched voice by the surgical treatment, like the type III-thyroplasty, or the voice therapy. The present study is, focusing on the latter treatment, to consider the efficiency of voice therapy for the mutational falsetto. The 7 patients who were diagnosed as mutational falsetto by the laryngologists, and treated by the voice therapist were selected as subjects. Their voices of pretherapy and posttherapy were analyzed on the aspects of acoustics and aerodynamics. Acoustic analysis was done by the MDVP(Multidimensional Voice Program) of CSL(Computerized Speech Lab, Kay Elemetrics, Co.), and aerodynamic analysis, by the Maximum Sustained Phonation of Aerophone II(Kay Elemetrics, Co.). By these measurements, we could find that fundamental frequency(F0) was significantly lowered, on the average, 65Hz. Maximum phonation time(MPT) was increased 4.57 second, and shimmer was decreased 1.644%, respectively, and each changes was statistically significant, too. On the average, jitter was decreased 0.499%, mean flow rate(MFR) was decreased 27.71ml/sec, and NHR was increased 0.023 which was the only parameter not showing improvement. But the changes of jitter, MFR and NHR were not statistically significant.

Purpose: This study aimed to investigate the current and future status of Parkinson's disease rehabilitation service in Busan. Methods: A literature search of domestic journals was conducted using the keywords "Parkinson's", "exercise", "rehabilitation", and "physical therapy". The chosen databases were Research Information Sharing Service (RISS), e-articles, and Korean studies Information Service System (KISS). International literature was searched in PubMed, Pedro, DOI, Publisher, CINAHL (EBSCOhost), and PsycINFO using the same combination of keywords. Results: The results of this study showed that 33 medical institutions provide Parkinson's disease rehabilitation service and five do not. Regarding the composition of Parkinson's disease rehabilitation teams, 15 medical institutions provide physical therapy, occupational therapy, and speech therapy as their rehabilitation program, 15 medical institutions provide physical therapy and occupational therapy, and three provide only physical therapy. The study found that muscle-strengthening, flexibility, endurance, and balance exercises were commonly provided in all 33 medical institutions for Parkinson's disease. Additional exercises were provided in only three medical institutions. The frequency was five times a week in 20 medical institutions. Conclusion: Medical institutions located in Busan provide a variety of Parkinson's disease rehabilitation services, not only in general hospitals but also in multiple medical institutions, although the composition of their Parkinson's disease rehabilitation teams and the frequency of treatment vary.

Objective: The purpose of this study was to examine the characteristics of prosody of ambiguous sentences in patients with right hemisphere damage(RHD). Methods: Sentences with each word prosodically focused were used to investigate. Several acoustic parameters such as intensity, F0, and duration were measured to identify characteristics of prosody in patients with lesions in the right hemisphere and normal controls. All speech samples were recorded using the Praat 4.3.14 software. Data were analyzed with the independent sample t-test using SPSS 18.0. Results: The results of this study are as follows: First, intensity of the first syllable of the focus word was different between the two groups in several sentences. Second, F0 was different between the two groups in all sentences. Third, duration was different between the groups in several sentences. Accordingly, prosody were varied and values of acoustic parameters differed due to the focus of utterance. The group with right hemisphere damage showed restricted prosody. Conclusions: Intensity, duration, and F0 are all used as elements of prosody in emphasizing structural and pragmatic meaning, but according to the focus, strength and duration were related to F0. In contrast, F0 has a significant linguistic difference, but there was a significant difference between the RHD and normal people, so F0 can be a discriminatory factor of rhyme evaluation of the right hemisphere damaged and it is necessary to accumulate more strong evidence through future research.

Backgrounds and Objects: Carcinoma of the tongue is the most common cancer of the oral cavity. A primary treatment strategy includes surgery and/or radiotherapy. Resection of the tongue often results in speech dysfunction, which depends on the site and extent of resection, type of reconstruction, and the mobility of remaining tongue. This study aimed to evaluate the characteristics of articulation errors that were resulted from the partial glossectomy without free flap reconstruction. Materials & Method : Articulation evaluations including speech intelligibility and percent of correct consonants (PCC) were performed for 24 patients who underwent partial glossectomy for their T1 or T2 tongue cancer. Mobility of the tongue, size of the resected tongue, and the history of adjuvant radiotherapy were analyzed for their relationship with the results of articulation evaluation. Results: Speech intelligibility score was $6.4{\pm}0.9$ (on 7-point scale) and overall PCC was 96.9%. There were close relationships between the size of resection and limitations in the tongue mobility, especially in "protrusion and elevation (r=-0.687)" and "retroflexion (r=-0.775)". Errors in "alveolar fricatives" and "palatal affricates" were also closely related with the size of resection (r=-0.537 and -0.538, respectively). PCC for "liquid sound" /r/ was 83.2%, which was closely related with the history of radiation therapy. Conclusion : Overall articulatory function was satisfactory in cases of early tongue cancer after partial glossectomy of a limited volume without flap reconstruction. However, the size of resection and the history of radiation therapy were closely related to the limitations in some types of tongue mobility and the resultant articulation errors.

Purpose: Adenoid hypertrophy is a physical alteration that may affect speech, and a speech disorder can have other negative effects on a child's life. Airway obstruction leads to constricted oral breathing and causes postural alterations of several oro-facial structures, including the mouth, tongue, and hyoid bone. The postural modifications may affect several aspects of speech production. Methods: In this study, we compared articulation errors in 19 children with adenoid hypertrophy (subject group) to those of 33 children with functional articulation disorders independent of anatomical problems (control group). Results: The mean age of the subject group was significantly higher (P=0.016). Substitution was more frequent in the subject group (P=0.003; odds ratio [OR], 1.80; 95% confidence interval [CI], 1.23- 2.62), while omission was less frequent (P<0.001; OR, 0.43; 95% CI, 0.27-0.67). Articulation errors were significantly less frequent in the palatal affricative in the subject group (P=0.047; OR, 0.25; 95% CI, 0.07-0.92). The number of articulation errors in other consonants was not different between the two groups. Nasalization and aspiration were significantly more frequent in the subject group (P=0.007 and 0.014; OR, 14.77 and 0.014; 95% CI, [1.62-135.04] and NA, respectively). Otherwise, there were no differences between the two groups. Conclusion: We identified the characteristics of articulation errors in children with adenoid hypertrophy, but our data did not show the relationship between adenoid hypertrophy and oral motor function that has been observed in previous studies. The association between adenoid hypertrophy and oral motor function remains doubtful.

Background and Objectives : Tongue-tie, or partial ankyloglossia, is manifested by an abnormally short and thick lingual frenulum. Degree of tongue-tie varies from the mild to the rare, severe and its treatment of choice is frenulotomy. Theoretically tongue-tie can affect expression of alveolar sounds. The purpose of this study is to evaluate the degree of articulation problem and to evaluate the efficacy of frenulotomy itself on alveolar sounds in tongue-tie patients. Materials and Methods : Prospectively, the authors performed preoperative and postoperative speech evaluation using picture consonants test for tongue-tie patients. Percentage of consonants correct(PCC), mean value of each alveolar phoneme depends on articulation site were evaluated. for exclusion of other articulatory improving factors except of frenulotomy itself, postoperative picture consonants test was performed 1 month after surgery. Results : Preoperative speech evaluation was performed to 37(male 21, female 16) patients and postoperative speech evaluation was performed to 17(male 9, female 8) patients, the other 20 patients were follow-up loss. Low PCC was observed in tongue-tie patients and PCC of female was higher an at of male in 2-4 years old patients. Overall PCC was improved after frenulotomy. Preoperative mean value of liquids and fricatives was lower than the other alveolar phonemes(p＜0.05) and it was improved postoperatively(p＜0.05). Conclusion : Frenulotomy itself can improve the articulation of liquids and fricatives on short follow-up. Speech therapy would be needful for improvement of the other alveolar phonemes.

This study examines the effectiveness of semi-occluded vocal tract exercise (SOVTE) conducted through telepractice for 10 female teachers who have experienced vocal discomfort while working in early childhood education facilities (childcare centers, kindergartens). The effects of SOVTE conducted through telepractice were evaluated based on the Korean voice handicap index (KVHI), the Korean version of the voice activity and participation profile (K-VAPP), vocal effort, and auditory perception evaluation by using the grade, roughness, breathiness, asthenia, and strain (GRBAS) scale. The results show that total, functional, and physical scores of KVHI significantly reduced after SOVTE. The total score in K-VAPP significantly reduced after SOVTE. Moreover, vocal effort significantly decreased after SOVTE. However, statistically significant differences were not noted in GRB scales before and after SOVTE. In conclusion, early childhood teachers experienced reduced vocal discomfort SOVTE conducted through telepractice. The study results indicate that voice therapy conducted through telepractice is an effective method for reducing vocal discomfort in early childhood teachers.

The aim of this study is evaluate the effect of a cognitive occupational therapy program on cognitive function, depression and hands function for patients with dementia living in a local community. A cognitive rehabilitation program of 10 weeks focusing on the occupational therapy is conducted from September to December 2012 on 21 patents (experimental group: 12, control group: 9) with dementia who are admitted to nursing homes in a metropolitan region. In the experimental group, the cognitive function, depression level, hand strength, and hand coordination ability is significantly improved after the application of the cognitive program (p<.05). In conclusion, the cognitive occupational therapy program may be a useful intervention for dementia. Because the therapeutic goal for dementia treatment is mainly concentrated on the amelioration of dementia symptoms, thus it is necessary to develop a various cognition training program that can be maintained the patient's residual functional capacity and returned to the social community through the early detection and the early intervention.

Objective : The purpose of this study was to investigate the age, motor function, and characteristics of feeding and articulation in children with spastic cerebral palsy. Methods : This study included 34 boys and 27 girls who lived in Seoul, Gyeonggi, Daegu, Daejeon, or Busan, and were diagnosed with cerebral palsy by rehabilitation doctors. A total of 61 children with cerebral palsy were identified as dependent variables for verbal intelligibility, diadochokinesis speed and intelligibility. Multiple regression analysis was performed. Results : Verbal intelligibility among the articulating abilities of children with spastic cerebral palsy was significantly associated with the non-speech mechanisms of cup drinking, and spoon feeding. Diadochokinesis speed was significantly associated with the speech mechanism of porridge feeding, the non-speech mechanism of cup drinking, and motor function. Diadochokinesis intelligibility also showed significant results with regards to the speech mechanism of porridge feeding and the non-speech mechanism of cup drinking. Conclusion : It is useful to evaluate and treat eating function by considering speech and non-speech mechanisms and motor function, according to eating function, among the variables related to articulation ability in children with spastic cerebral palsy. In addition, it would be very useful to study the improvement of articulation abilities after developing and applying a feeding program for children with cerebral palsy.
