With the booming complementary medicine as a social trend of well-being, treatment by the sound waves of six kinds of syllables is believed to restore that healthy balance to the body. Sound therapy refers to a range of therapies in which sound is used to treat physical and mental conditions. Healing is done by transmitting beneficial sound to the affected area related to five viscera and six bowels. The healing sound may be produced by a voice. sound wave vibrations are to treat physical and mental conditions. In general, this therapy is based on the theory that all of life vibrates, including people's bodies. When a person's healthy resonant frequency is out of balance, physical and emotional health is affected. When a person's healthy resonant frequency is out of balance, physical and emotional health is affected. This paper focuses on the sound therapy by six syllables of 'hyu', 'huo', 'ho', 'sa', 'chi' and 'hui'.

Cleft lip and palate is a congenital deformity which needs a professional and consistent management from the birth and along with the physical growth of patients. The patients with cleft lip and palate can have general speech problems with resonance disorders, voice disorders and articulation disorders after the successful primary surgical management and the physical growth. Speech problems of Cleft lip and palate are characterized hypernasality, nasal air emission, increased nasal air flow, and aberrant speech marks which decrease intelligibility. These speech problems of cleft lip and palate can be treated with the secondary surgical procedure, the application of temporary prosthesis and the effective and well-timed speech therapy. The speech and language problems of cleft lip and palate, the general procedures and schedules of the speech assessment and therapy based on the multidisciplinary approach are introduced for the patients with cleft lip and palate, their family and the other members of the cleft palate treatment team.

Sound pressure level, subglottic air pressure, vital capacity, adduction/abduction rate, and phonatory efficiency were measured in 19 opera singers, 17 Korean traditional 'Pansori' singers, and 20 non-singers; subjects' mean age was 25.9(SD=7.2) and the singers had been singing professionally for 5-10 years. One-way ANOVA and Scheff$\w'{e}$ post-hoc analysis were used to analyze aerodynamic data and to identify significant differences among groups. Sound pressure level, peak subglottic air pressure, and phonatory efficiency were found to be significantly different among three groups of the subjects. Differences in aerodynamic properties were discussed for their significance in diagnosis and treatment of voice disorders in professional singers.

The use of professional retirement personnel who have largely left their economic activities due to the retirement of baby boomers is a modern task and is emerging as a social issue. This study aims to explo re the perception of professional retirees' overseas volunteer experience as NGOs and seek ways to utilize pro fessional retirement personnel. This study is a qualitative study using photo-voice, and the participants in the study are retirees of retirement age from professions with experience in NGO overseas service. Data were collected through group activities and individual interviews, and data were analyzed using participatory analysis and subject analysis. The perception derived from the study was that NGO overseas service is the best job to be safe and raise the national status, and that information on this is wanted to be provided in retirement education. In conclusion, retirement education for the expansion of NGO overseas service was conducted not only in public enterprises but also in general workplaces to discuss ways to prepare before retirement, and the operation of the Retired NGO Overseas Volunteer Information Service Center was suggested. This study is meaningful in presenting basic data for preparing alternatives to social welfare policies in old age after retirement through the recognition of the experience of professional retirees in overseas NGO service

Background and Objectives : With the development of computerized systems, an objective evaluation methods of nasal speech and nasal geometry have become readily available by means of a simple, noninvasive technique. In this study, we assessed the nasality, nasal formant, nasal volume and nasal area in patients with hypertrophic rhinitis before and after turbinate surgery. Material and Method : With the nasometer, we measured nasalance, which reflects the ratio of acoustic energy output of nasal sounds from the nasal and oral cavities. With CSL 4300B, we measured nasal formants. We used acoustic rhinometer to measure nasal area and nasal volume. Postoperative changes of above factors were compared with preoperative values. Paired t-test and Pearson's correlation were used for statistical analysis. Results : The first nasal formant frequency, nasalance scores of three passages(baby, mamma and rabbit passages), minimal cross sectional area(MCA) of narrow side, nasal volume of narrow side and nasal volume of wide side had increased significantly after turbinate surgery (p <0.05). The MCA and nasal volume of narrow side and MCA of wide side showed significant correlation with nasalance score of rabbit passage and baby passage showed significant correlation with nasal volume of narrow side(p<0.05). Conclusion : There were significant increases in nasalance scores, first nasal formant frequency, MCA and nasal volume after turbinate surgery. Thus, we must consider the possibility of voice changes postoperatively in professional voice users.

Background and Objectives: It has been suggested that tonsillectomy possibly causes changes of voice because the morphology of the vocal tract is altered. This may cause serious problems for professional voice users. Materials and Method: Subjects were 26 patients. The oral and nasal sound spectrum of oral vowel /a/, /e/ and /i/ were measured before and after tonsillectomy. The formant frequencies and intensities for oral and nasal spectra were compared. The nasality and fundamental frequencies for oral vowel were measured. Results: The first formant frequencies for oral spectra of all vowels were not changed after surgery, but the second formant frequencies were increased significantly after surgery in the vowel /e/ and /i/. The first and second formant intensities for oral spectra were increased significantly after surgery in the all vowels. The first and second formant frequencies for nasal spectra of all vowels were not changed after surgery, but their intensities for nasal spectra were increased after surgery. The nasalities for oral vowel were not changed after surgery. Conclusion : Tonsillectomy appeared to change the spectral features of oral and nasal components of oral vowel, especially spectral intensities.

In this paper, we proposed an automatic monitoring system for contact center in order to manage customer's complaint and agent's quality. The proposed system allows more accurate monitoring using emotion recognition and keyword spotting method for neutral/anger voice emotion. The system can provide professional consultation and management for the customer with language violence, such as abuse and sexual harassment. We developed a method of building robust algorithm on heterogeneous speech DB of many unspecified customers. Experimental results confirm the stable and improved performance using real contact center speech data.

A comparative phonetic analysis of Yodel singing and Belcanto singing by the electroglottographic(EGG) measurement was done in three singers. One professional tenor singer(SDI) who is also well trained in Yodel singing, another yodler(KWS) who is not so trained in Belcanto singing, and the other training tenor singer(CSK) who is not well trained both yodel and Belcanto singing. Closed quotient(CQ), speed quotient(SQ) and fundamental frequency (F0) at the initial modal part(I) , middle falsetto part(M), and final modal part(F) of the same phrase were measured by EGG machine and program(Kay model 4338). In the middle part, not only CQ but also SQ of the Yodel singing were much smaller than that of Belcanto singing in all three singers. However, accuracy of parameters in Belcanto singing of the yodler(KWS) and both Yodel singing and Belcanto singing of the training singer(CSK) were inferior to that of trained tenor singer(SDI). Possible advantages of utilizing Yodel singing training under the guidance of feedback control by the EGG for hyperfunctional voice disorders such as vocal nodules were discussed.
