다국어 초록 (Multilingual Abstract)

The purpose of this study was to examine the effect of hypernasality reduction and articulation accuracy improvement of cleft lip and palate children by using a program of anterior tongue placement. Three cleft lip and palate children were selected as subjects. The subjects were normal in intelligence, hearing, eyesight and visual perception. They also didn't show complete velopharyngeal incompetency innately. To select subjects, the following tests were applied;
a) K-WPPSI intelligence test, b) Preschool Language Scale, c) Picture Consonant Articulation Test, and d) Nasalization Diagnosis Method for Cleft Palate. A 45-minute session was taken four times a week. I applied the anterior tongue placement program developed by myself to each subject. This program was made to improve posterior tongue placement of cleft lip and palate children, using /ㄷ/, from low vowel to high vowel, and from meaningless syllable to sentence. To examine the hypernasality improvement by a nasometer using the anterior tongue placement program, I performed pre-post evaluation, and performed midterm evaluations 3 times. To examine the articulation accuracy improvement effect, two speech pathologists participated in the pre-post evaluation. The reliability between the three pathologist including the research was 83%. To examine the transfer effects of the hypernasaJity improvement in words including untrained phonemes, I performed pre-post evaluation. The results of this study were as follows; First, after I performed the anterior tongue placement program by using a nasometer on my subjects, the nasalance of subject A decreased from 25.53% to 12.34%. The nasalance of subject Band C decrased from 31.03% to 14.36% and from 16.91 % to 7.38% respectively. Second, after I performed the anterior tongue placement program, the articulation accuracy improvement effect of subject A was 14%, and subject B and C was 13% and 9% respectively. Third, after I performed the anterior tongue placement program, the hypernasality improvement transfer effect in words including untrained phonemes of subject A was 3.24%, and subject Band C was 3.39% and 2.27% respectively. The conclusions of the study were as follows; First, the anterior tongue placement program by a nasometer had an effect on the hypernasality improvement of deft lip and palate children. Second, the anterior tongue placement program had an effect on the articulation accuracy improvement of deft lip and palate children. Third, the anterior tongue placement program had an effect on the hypernasality improvement transfer in words including untrained phonemes The results of this study showed that this anterior tongue placement program was effective for cleft palate children.
