The purpose of this study was to research the effects of vocalization on upper extremity motion during occupational performance and to compare non-meaning and meaning vocalization. Experiments were performed on 30 subjects. They had no medical history of neurological problems with their upper extremities. Using a tea cup, a tea tray, and a tea spoon, they set a table during vocalization. We used meaning and non-meaning vocalization with the subjects. An example of meaning vocalization would be naming something, and an example of non-vocalization would be saying, "Ah." We used a 3-D analysis system called CMS-HS. We analyzed the motion in the angular velocity and acceleration of the elbow while recording performance time. The results of this study showed that vocalization enhanced the angular velocity and acceleration of the elbow, and also enhanced performance time. In short, vocalization improved upper extremity motion by making it faster and smoother. There were no significant differences between meaning and non-meaning vocalization.

All singers can often develop voice trouble secondary to vocal abuse and overuse, but it is well known that traditional Korean singer (pansori) develop voice disorders more frequently than western style sunger. While laryngological concern for voice disorders arising in professional singers has received some attention, empirically motivated investigations of the underlying acoustic features of the singing voice have been relatively limited. Since all singers have a good knowledge of the voice and voice training, they would hardly give consent for treatment to a doctor unless he understood their desire to maximize their voice quality. The components of this report are composed of breathing, basic ekement, and vocalization, essencial fact, for getting a perfect voice for pansori. The breathing is based on hypogastric breathing. The main functions of breathing are energy and power of utterence, tempo of rhythm and seperating paragraph and controlling feelings according to dramatic situation. Vocalization is based on general vocalization. Main uses of it are maintaining singer's tone and harmony of cosmetic dual force.

Tracheostomy refers to a surgical incision created in the neck to allow direct air entry into the trachea bypassing the upper respiratory tract including the oral and nasal cavities. Normal vocalization and swallowing are limited immediately postoperatively; however, gradual recovery of vocalization and swallowing function can be initiated, following improvement in the causative condition that necessitated the tracheostomy. Duration of the tracheostomy depends upon the patient's condition, and the degree of vocalization and swallowing function recovery after tracheostomy tube removal varies widely across patients. In this review, we investigated the changes associated with vocalization and swallowing function in patients who underwent tracheostomy and have discussed the various approaches and voice rehabilitation treatments to aid with normal recovery.

This study was conducted to investigate the effect of weaning period on the vocalization frequency of Hanwoo calf. Twelve Hanwoo calves were allocated into 4 groups, control (forced weaning on 90days) and treatment (weaning on 70, 90 and 120days with 5 adaptation days). After weaning, behavior and vocalization of Hanwoo calves were recorded on 3 consecutive days with closed circuit television (DTC-R5254, Digite Co., Ltd., Korea) and digital audio tape recorder (SR-900, Idamtech Co., Ltd., Korea). Vocalization frequency of Hanwoo calf were not significance difference with control and treatment group. Thus, additional studies of feed intake and body weight gain were needed to determine the weaning period of Hanwoo calves.

This study investigated longitudinally early vocalization and phonological developments of typically developing children. Ten typically developing children participated in the study from 9 months to 18 months of age. Spontaneous utterance samples were collected at 9, 12, 15, 18 months of age and phonetically transcribed and analyzed. Utterance samples were classified into 5 levels using Stark Assessment of Early Vocal Development-Revised(SAEVD-R). The data analysis focused on 4 and 5 levels of vocalizations classified by SAEVD-R and word productions. The percentage of each vocalization level, vocalization length, syllable structures, and consonant inventory were obtained. The results showed that the percentages of level 4 and 5 vocalizations and word significantly increased with age and the production of syllable structures containing consonants significantly increased around 12 and 15 months of age. On average, the children produced 4 types of syllable structure and 5.4 consonants at 9 months and they produced 5 types of syllable structure and 9.8 consonants at 18 months. The phonological development patterns in this study were consistent with those analyzed from children's meaningful utterances in previous studies. The results support the perspective on the continuity between babbling and early speech. This study has clinical implications in early identification and speech-language intervention for young children with speech delays or at risk.

이 연구는 합창에 영향을 미치는 비언어 커뮤니케이션 가운데 가사의 의미 형성에 핵심적인 요소인 유사 언어의 효율적 활용 방안을 모색하기 위한 목적으로 수행되었다. 커뮤니케이션에서 유사언어는 언어가 가진 의미를 더욱 풍부하게 표현할 수 있게 해주는 비언어적 요소로, 합창에서는 가사의 발성과 딕션이 대표적인 유사언어이다. 그런데 그동안은 합창의 음악적 표현을 강조하면서 발성을 중시한 나머지 딕션은 상대적으로 소홀히 함으로써 합창에서 표현하고자 하는 가사의 의미가 청중에게 효과적으로 전달되지 못하는 경우가 많았다. 그러나 합창에서 발성은 딕션과 별개의 것이 아니라 서로 조화를 이루어야 음악적인 차원에서뿐 아니라 커뮤니케이션 차원에서도 완성도가 높은 합창연주가 가능하다. 이 연구는 합창 지휘자로서의 활동 경험과 커뮤니케이션에 대한 이론적 지식을 토대로 한국어 합창에서 활용할 수 있는 효과적인 딕션 방법을 제시하고 있다.

It's not easy to produce very high tones during singing for not only untrained ordinary people but also even trained singers. To get high singing tones from the low tones, some trained singers used to use a distinguished singing technique, Passaggio (vocal register transition). The purpose of this study is to compare several voice parameters variation between when to sing with using the passaggio technique and to sing without using it. We selected 18 male singers (tenor 8, baritone 10), who had more than 7 years of experience and were well trained in passaggio technique. Simultaneous measurements of fundamental frequency (F0), mean flow rate (MFR), intensity (I), and subglottal pressure (Psub) were performed using the phonatory function analyzer (Nagashima). For the tenor, target tones /a/ were presented: 1) easy phonation: $B_{2}$, 2) high tone without passaggio: F$#_{3}$ 3) high tone with passaggio: F$#_{3}$. For the baritone, target tones /a/ were presented: 1) easy phonation: G$#_{3}$, 2) high tone without passaggio: D$#_{3}$, 3) high tone with passaggio: D$#_{3}$. F0 of the target tones between non-passaggio group and passaggio group was almost the same in both tenor and baritone groups. Intensity of the non-passaggio and passaggio vocalization was much louder than that of easy phonation and pasaggio was louder than non-passaggio vocalization (especially statistically significant in baritone singers). MFR of the passaggio vocalization was greater than non-passaggio vocalization in both tenor and baritone group, but statistically significant only in baritone. Psub of the passaggio vocalization was greater than that of the non-passaggio vocalization in both tenor and baritone group, but statistically not significant in tenor.

This study investigated changes in the prelinguistic vocal production of typically developing infants aged 5-20 months based on Stark Assessment of Early Vocal Development-Revised (SAEVD-R). Fifty-eight typically developing infants participated in the study, and they were divided into four age groups, 5-8 months, 9-12 months, 13-16 months, and 17-20 months of age. Vocalization samples were collected from infants' play activities and were classified into 5 levels and 23 types using SAEVD-R. The results revealed that the four age groups showed significant differences in production proportion of vocalization levels. Level 1, 2, 4, and 5 vocalizations exhibited significantly different across the four age groups. Level 3 was predominantly produced across every age group. Therefore, the vocalization level was not significantly different across the four age groups. Especially, vowels in Level 3 vocalization predominantly produced across all ages during a long period. Also, significant increases in the proportion of Levels 4 and 5 occurred after 9 months, which suggested that the production of cannonical syllables is a key indicator of advancement in prelinguistic vocal development. The results have clinical implication in early identification and speech-language intervention for young children with speech delays or at risk.
