본 연구의 목적은 만 5세 이전에 인공와우이식을 받은 아동들의 일반학교 통합 후 학교 수행력을 건청 아동과 비교하여 알아보고, 학교 수행력과 관련된 변인을 알아보고자 하는 것이다. 이를 위해 담임 교사에게 인공와우이식 아동 1명과 건청 아동 1명의 학교 수행력을 설문지를 통해 평가하게 하였다. 그 결과, 인공와우이식 아동은 저학년보다 고학년에서 수행력이 더 낮은 것으로 평가되었다. 건청 아동과의 비교 결과, 저학년에서는 의사소통능력에서 차이를 보였고, 고학년에서는 학교 수행력의 네 하위영역 전체에서 건청 아동에 비해 유의하게 낮은 수행력을 보였다. 관련 변인을 살펴보면, 의사소통능력은 수술 연령, 청각적 수행력, 언어능력, 재활참여정도와 상관관계가 있었고, 사회-정서 적응은 청각적 수행력, 언어능력, 재활 참여정도와 상관관계가 있었으며, 학업성취는 청각적 수행력, 언어능력과 관련이 있었다. This study aims to investigate the school performance of children who received cochlear implantation under age of five and have been integrated into regular elementary schools compared to that of normal hearing children, and to examine the factors associated with the school performance of these children. Classroom teachers completed the questionnaires comprised of 26 items regarding communication skill, psycho-social adjustment, academic achievement, and general integration adjustment for 37 children with cochlear implants and 37 normal hearing children attending the same classrooms. As a result, the school performance of higher grade students with cochlear implants was significantly lower than that of lower grade students with cochlear implants. In the lower grade, students with cochlear implants showed significantly lower communication abilities than normal hearing children. On the other hand, in the higher grade, students with cochlear implants showed significantly lower performance on four aspects of school performance. In terms of related factors to school performance, communication abilities were correlated with age at implantation, auditory performance, language ability, and habilitation, and social-emotional adjustment was related with three variables except age at implantation. Academic achievement was related with auditory performance and language ability.

본 연구는 초등학년 인공와우이식 아동의 음운인식능력과 음운인식 발달동향을 분석하는데 그 목적이 있다. 이를 위하여 인공와우이식 아동의 음운인식능력을 과제 수준 및 과제 종류별로 건청 아동과의 비교를 통해서 알아보고, 인공와우이식 아동의 학년에 따른 음운인식 발달 동향을 분석하였으며, 음운인식 발달에 대한 수술연령의 관련성을 알아보았다. 79명의 인공 와우이식 아동과 113명의 또래 건청 아동을 대상으로 음운인식검사를 시행하였다. 과제 수준별 비교 결과 음절 과제에서는 초등 1학년까지만 인공와우이식 아동과 건청 아동 간에 차이가 있었고, 그 이후에는 집단 간 차이가 없었다. 음절체 + 종성 과제와 음소 과제는 초등 2학년까지만 건청 아동과 차이가 있었고, 3학년부터는 차이가 나타나지 않았다. 발달동향을 분석한 결과 음절과 음절체 + 종성 과제는 초등 2학년까지 학년에 따른 유의한 차이를 보였으나 이후에는 더 이상 유의한 차이가 나타나지 않았다. 음소 과제에서는 초등 2학년과 3학년 간에 유의한 차이가 있었으나, 3학년 이후에는 더 이상 학년에 따른 차이가 나타나지 않았다. 수술연령과 음운인식능력의 관련성을 분석한 결과 초등 저학년과 고학년 모두 수술연령과 음운인식 간에 상관관계가 없는 것으로 나타났다. 이상의 결과는 인공와우이식 아동의 음운인식 및 읽기 중재 프로그램 개발에 대한 기초적인 자료로 활용될 수 있을 것으로 사료된다. This study aims to analyze the phonological awareness abilities and development trends of phonological awareness for children with cochlear implants in elementary school grades. For these purposes, we compared the phonological awareness abilities of children with CIs with those of normal hearing children, and to analyze the differences of phonological awareness abilities of children with CIs according to the grades. Furthermore, this study examined the relationships of phonological awareness abilities and age at implantation in these children. 79 children with CIs and 113 CA matched normal hearing children were executed by the phonological awareness test. The results showed that there were significant differences between children with CIs and normal hearing for the first grade on syllable tasks, and were significant differences between groups up to the second grade in phoneme tasks. There were no significant differences of syllable tasks scores in terms of grade, whereas there were significant differences of phoneme task scores according to the grades up to the third grade in children with CIs. There were no significant relationships of between phonological awareness and age at implantation in children with CIs. These results could be used to develop the phonological awareness and reading intervention program for children with CIs.

본 연구는 보청기와 인공와우 기기에 대한 대학생들의 인식 및 태도를 알아보고, 보청기와 인공와우 기기에 대한 태도와 관련된 변인을 알아보고자 하는 것이다. 이를 위해 114명의 대학생에게 보청기와 인공와우 기기를 착용한 조건과 착용하지 않은 조건에 대해 형용사형 척도를 작성하게 하였고, 보청기와 인공와우 기기에 대한 태도 설문 조사를 시행하였다. 연구결과를 살펴보면 보청기와 인공와우 기기 모두 착용하지 않은 조건보다 착용한 조건에 대해외모, 성격, 성취에서 더 부정적인 평가를 받았다. 성별로 비교한 결과 여성 보다는 남성에대한 평가가 더 부정적이었다. 또한, 보청기보다 인공와우 기기에 대해 사회적 낙인, 개인적견해, 지식에서 더 부정적인 태도가 나타났다. 관련된 변인을 분석한 결과 성별과 안경 혹은콘텍트렌즈 착용 유무가 인공와우 기기 착용자에 대한 사회적 낙인과 상관관계가 있는 것으로 나타났다. 이는 한국의 대학생에서도 보청기나 인공와우 기기에 대한 ‘보청기 효과’와 ‘인공와우 효과’가 있음을 보여주는 결과이며, 보청기보다 더 외형적으로 드러나는 인공와우 기기에 대해 더 부정적인 태도를 가짐을 보여주는 결과라고 할 수 있다. This study aims to investigate the perception and attitude of university students about hearing aid and cochlear implant, and to examine the variables related to their attitudes towards hearing aid and cochlear implant. The subjects were 114 university students, who were asked to see the pictures on wearing conditions and non-wearing conditions of hearing aid and cochlear implant and complete the adjective format scale . Also, they saw the pictures of hearing aid wearer and cochlear implant wearer, and completed the questionnaires about attitude for hearing aid and cochlear implant. Results show that university students show more negative perception about wearing conditions than non-wearing conditions on appearance, personality, and achievement for both hearing aid and cochlear implant. Attitude for cochlear implant was more negative than that for hearing aid on social stigma, viewpoint, and knowledge. As a result of analyzing related factors for attitude about hearing aid and cochlear implant, sex and wearing glasses or contact lenses were related to the social stigma for cochlear implant users. These results show that there exist ‘hearing aid effect’ and ‘cochlear implant effect’ in Korean university students, and their attitudes are more negative for cochlear implant than for hearing aid.

허민정 ( Min Jung Heo ),안성우 ( Seong Woo Ahn ) 한국특수교육문제연구소 2011 특수교육저널 : 이론과 실천 Vol.12 No.3

본 연구는 인공와우이식 학생의 음운기억을 생활연령이 같은 건청 학생 그리고 읽기수준이 같은 건청 학생의 음운기억과 비교하여 인공와우이식 학생의 음운기억 수준 및 발달양상을 알아보고, 이들의 음운기억이 언어 및 읽기와 어떠한 관련성을 가지는지를 비교하여 인공와 우이식 학생의 언어 및 읽기 발달에서 음운기억의 역할을 알아보고자 하는데 그 목적이 있다. 이를 위하여 초등 고학년 인공와우이식 학생 36명과 생활연령이 같은 건청 학생 48명, 읽기수준이 같은 건청 학생 44명을 대상으로 음운기억검사, 문장이해검사, 읽기이해검사를 시행하였다. 연구 결과, 인공와우이식 학생은 생활연령이 같은 건청 학생과 읽기연령이 같은 건청 학생보다 음운기억에서 낮은 수행력을 보였으며, 학년에 따른 음운기억의 발달이 나타나지 않았다. 또한 인공와우이식 학생의 음운기억은 읽기연령이 같은 건청 학생에서와 유사하게 언어능력 및 읽기이해와 상관이 있는 것으로 나타났으나 음운기억보다는 언어능력이 읽기와 더 높은 상관이 있었다. This study aims to investigate the level and developmental patterns of phonological memory for students with cochlear implants compared with those of chronological-age matched- and reading-age matched normal hearing students, and explore the role of phonological memory on language and reading development through analyzing the relationships of phonological memory, language, and reading for these students. For these purpose, syllable repetition test, sentence comprehension test, and reading comprehension test were performed for 38 higher-grade elementary school students with CIs, 48 chronological-age matched normal hearing students, and 44 reading-age matched normal hearing students. Results indicated that phonological memory skills of students with CIs were lower than those of CA matched-and RA matched normal hearing students regardless of conditions of the test, and their phonological memory skills didn’t develop with grade. Also, phonological memory of students with CIs was related with language and reading abilities similar to reading-age matched normal hearing students, but language had higher relationships with reading than phonological memory.

The aims of this study were to investigate the school performance of children with cochlear implants who have been integrated into regular schools from the perspective of the classroom teacher and to examine the factors associated with the school performance.   Forty eight prelingually deaf children who were integrated into regular classrooms were included in this study. Classroom teachers completed the questionnaire comprised of 19 items regarding communication skill, psycho-social adjustment, and academic achievement of children with cochlear implants in regular classrooms. To identify the factors associated with the school performance of these children, stepwise multiple regression analysis was performed using age at implantation, duration of implant use, preoperative hearing thresholds, speech perception ability, and language ability as independent variables.   The average ratings on communication skill and psycho-social adjustment were 3.61 (SD=0.66) and 3.69 (SD=0.67), respectively. Academic achievement was evaluated as being somewhat poor. Better communication skill and better academic achievement were associated with better language ability. Better psycho-social adjustment was associated with better speech perception ability. Most of children with cochlear implants in mainstream classrooms were evaluated as being well adjusted in aspects of communication skill and psycho-social adjustment, whereas substantial percentage of them were perceived as performing at below average level by teachers. Language and speech perception abilities were important factors for school performance in children with cochlear implants.

허민정(Min Jung Heo),안성우(Sung Woo Ahn),부성현(Sung Hyun Boo) 한국언어치료학회 2011 言語治療硏究 Vol.20 No.2

The purpose of this study is to analyze the relationships of phonologocal memory, speech perception, age at implantation, and preoperative auditory performance on receptive vocabulary abilities of school-aged children with cochlear implants. The subjects of this study were Eighty-four children who received the cochlear implantation under age of five and used oral communication. Path analysis was used to analyze the relationships of these 4 factors on receptive vocabulary abilities of children with CIs in multi-level modeling. The results of path analysis showed that phonological memory, speech perception, and age at implantation affected receptive vocabulary abilities in direct routes. Preoperative auditory performance had direct effects on phonological memory and speech perception, and indirect effects on receptive vocabulary abilities through phonological memory and speech perception.

안성우(Sung Woo Ahn),허민정(Min Jung Heo),서중현(Jung Hyun Seo) 한국언어치료학회 2012 言語治療硏究 Vol.21 No.3

The purpose of this study is to analyze the effects of letter-knowledge, letter-sound correspondence, age, and working memory on phonological awareness in Korean. The subjects of this study were 1,043 children between the ages of for and seven. Step-wise multiple regression was used to analyse the influences of letter-knowledge, letter-sound correspondence, age, and working memory on phonological awareness. The results suggest that letter knowledge had the greatest variance on syllable awareness, while age had the greatest variance on phoneme awareness. Letter knowledge had the greatest effects on numbering and deletion tasks, while the central executive of working memory had the greatest effect on discrimination, blending, and substitution tasks.

종격동 종양 환자의 전신마취 시 발생한 심각한 저산소혈증 및 저혈압 -증례보고-

박상진 ( Sang Jin Park ),허민정 ( Min Jung Heo ) 대한마취과학회 2009 Korean Journal of Anesthesiology Vol.57 No.6

Mediastinal masses may cause compression of vital structures such as major airways, the superior vena cava and, rarely, the pulmonary artery. The latter could cause cardiorespiratory compromise during or after induction of general anesthesia. We observed a case of a 45-year-old woman with an anterior mediastinal mass that caused severe hypoxemia and hypotension during sternotomy for mass resection, probably by pulmonary artery compression. Immediately upon opening the chest to relieve pulmonary artery compression, oxygen saturation and blood pressure returned to normal. Therefore, we suggest that unexpected hypoxemia and hypotension in a patient with a mediastinal mass can be due to pulmonary artery compression. (Korean J Anesthesiol 2009; 57: 754∼7)

안성우(Seoung Woo Ahn),허민정(Min Jung Heo),김유(You Kim),김미경(Mi Kyung Kim) 한국언어치료학회 2011 言語治療硏究 Vol.20 No.3

This study examined the developmental nature of phonological awareness skills of typically developing children in Korea. This study included a total of 1,043 participants between 49 months and 84 months of age. Participants completed 10 measures of phonological awareness. Results indicate that age contributed unique variance to the development of phonological awareness. This study presents the array of skills and ordered in a developmental continuum based on the results. Participants had a higher awareness of the syllable unit awareness than phoneme awareness and their syllable unit awareness grew at a much faster rate than phoneme awareness. As children grew, their phonological awareness grew over a period of time. Participants had a higher awareness of the counting sound than sound deletion, sound blending, sound matching, and substitution.
