This study attempted to determine the effects of a cooperative and cognitive group therapy compared to individual therapy in 24 aphasic subjects. Two dependent variables were measured overall language performance, functional communication skills. 18 subjects with different types and severity of aphasia participated in the group therapy. 6 aphasic subjects participated in the individual therapy and they functioned as a control group. The subjects were ranged from 27 to 59 years in age. The group therapy using the cooperative learning utilized the following procedures. First, 6 aphasics constituted 1 group where each subject performed a task and they monitored one another. Second, 2 aphasics consisted 1 group and they cooperated to perform a task. Third, 3 groups with 2 aphasics in a group competed one another in a task where the 2 aphasics had to cooperated. Finally, the investigator gave the feedback to the group and she and the subjects discussed the overall procedures of the therapy. The above mentioned 2 tests were administered pre- and post-treatment. A repeated two-way ANOVA was performed for analysis. The results showed that the group therapy was more effective in improving overall language performance as compared to the individual therapy. And, the group therapy was more effective in increasing functional communication skills as compared to the individual therapy.

조성미,정옥란,이상욱 한국음성과학회 2004 음성과학 Vol.11 No.4

This study attempted to provide a spectrum analysis for quantitative evaluation of singing voice quality of singing students rather than the presence or absence of the singer's formant. The regression analysis was used to analyse the relationship between ringing quality, SPR, and SPP of singing voice of college student subjects majoring in music. This study measured singing power ratio (SPR) in 41 singing students. Digital audio recordings were made in sung vowels for acoustic analyses. Each sample was judged by 1 experienced singing teacher and 4 voice pathologists on one semantic bipolar 7-point scales (ringing-dull). The results showed that the SPR and SPP had significant correlations with ringing Quality. The SPR had a significant relationship with ringing quality on singing voice in singing students. The SPR can be an important quantitative measurement for evaluating singing voice quality.

학교 내의 문서 전달은 교육청과 같은 규모가 큰 교육기관과는 달리 소규모라는 점 때문에 소흘히 여겨져 왔다. 외부의 행정 환경 변화에 따라 학교 내의 행정 서비스 전달 체계도 그 구조와 틀을 쇄신할 필요가 있다. 이러한 취지에서 본 논문은 실제 학교 현장에서 활용할 수 있도록 통보형 XML 공문서 관리를 위한 프레임웍을 설계하고, 컴포넌트 관계로 모델링하여 JSP 컴포넌트 기반의 공문서 관리 시스템을 구현하였다. 결과적으로 본 시스템은 기한이 임박한 공문서와 같은 교육활동에 부정적 영향을 미치는 요소를 줄이고 문서 관리 체계의 전산화로 학교 내 행정 서비스 환경을 개선한다는데 의의가 있다. Delivering documents within school itself, has been ignored, since it is not considered as a large organization such as government education agencies. It is necessary to change the procedures in delivering official documents within school's administrative services along with the outside administrative procedure changes. For the above purposes, this study can be practiced toward the actual schools therefore it is to design the framework for Distributable Official XML Document management and to implement official document management system based on JSP component. As a result, this system will reduce the negativity in producing the time critical official documents in educational activities. It is important at the fact that electronic document management procedures will incredibly improve the quality in school's administrative services.

유재연,정옥란,장태염,고도홍 한국음성과학회 2003 음성과학 Vol.10 No.3

The purpose of this study was to conduct a correlational analysis among Fo, Jitter, Shimmer, and NHR(HNR), and NNE estimated by three speech analysis softwares, MDVP, Praat and Dr, Speech. Thirty females and 15 males with normal voice participated in the study. We used Sound Forge 6.0 to record their voice. MDVP, Praat and Dr. Speech were used to measure the acoustic parameters. The Pearson correlation coefficient was determined through a statistical analysis. The results came out as follows: Firstly, there was a strong correlation between Fo and Shimmer of both instruments. However, there was no correlation between Jitter of both instruments. Secondly, Shimmer showed a stronger correlation with HNR, NHR, and NNE than Jitter. Therefore, Shimmer was considered to be more useful and sensitive parameter to identify dysphonic voice compared to Jitter.

허명진,정옥란 한국언어치료학회 1997 言語治療硏究 Vol.6 No.1

The purpose of this study is to investigate and compare acoustic characteristics of 36 hearing impaired speakers with 36 normal control speakers during the sustained phonation of /a/, using CSL VP2 model 4331(Kay Elemetrics Corp.). The age ranged from 6 to 20 for both groups. The acoustic data were collected on pitch, intensity, jitter, and shimmer. This study attempted to explore if the 4 parameters change as a function of age and gender. In addition, the present study tried to determine if the 4 parameters differ between the normal subjects and the hearing impaired subjects. Finally, this study explored if correlation exists between pitch and jitter, and intensity and shimmer in both groups. The results were as follows: Firstly, there was a significant difference between the 2 groups in terms of pitch, intensity, and jitter in that those values were higher for the hearing impaired group. However, minimum intensity value was lower for the hearing impaired group. In addition, age and gender did not affect acoustic characteristics of voices of hearing impaired individuals unlike normal individuals. Secondly, normal subjects' pitch decreased as the age increased. Also, normal male subjects' jitter decreased as the age increased. The hearing impaired subjects did not show any change. Thirdly, normal female subjects' pitch, intensity, and jitter were higher than that of male subjects. The hearing impaired male subjects' pitch was lower than that of female subjects, whereas the reverse was true for intensity. Finally, the hearing impaired group showed correlation between pitch and jitter, and between intensity and shimmer. Namely, their jitter increased as their pitch increased, but their shimmer increased as their intensity decreased. However, no correlation existed between pitch and jitter, or intensity and shimmer for the normal group.

성전환자와 정상인이 발성한 모음의 음향분석과 지각실험

조성미,정옥란 한국음성과학회 2003 음성과학 Vol.10 No.3

This study compared F0 and the first three formants of eight Korean monophthongs produced by nine transgenters (male to female) to those of eighteen normal adults. Voice analysis was done by Praa (version 4.4049). A one-way ANOVA wih Turkey HSD post hoc tests were performed to determine statistical differences in F0 and forma values obtained from transgender, and normal male and female subjects. Results indicated that there was no significant difference in F1 of /u/, /Λ/, and /o/, F2 of /u/, /Λ/, and /i/ and F3 of /u/ among the 3 groups (transgender, normal males and normal females). However, in the comparison of transgender vs. males, a significant difference was observed in F0 of /o/, and F2 of /i/, /a/, /e/, and /ae/ an F3 of /e/. Furthermore in the comparison of transgender vs. females, a significant difference was also observed in F0 of all vowels, F1 of /i/, /a/, /e/, /ae/, and /i/, F2 of /i/, an /ae/, an F3 of /i/, /a/, /Λ/, /e/, /ae/, /i/, an /o/. Also, perceptual judgment of the transgender' voice came out somewhat correlated strongly with their F0 values but not much with the formant values. It was concluded that he transgender' acoustic parameters are plead in between those of the normal males and females in terms of fundamental and formant frequency analyses of vowels. Thus, it was assumed that those differences might stem from the transgender' original big resonating cavities.
