고도난청아(高度難聽兒)에 대(對)한 잔존청력(殘存聽力)을 조사(調査)하기 위(爲)하여 1973년(年) 3월(月) 10일(日)부터 동년(同年) 11월(月) 28일(日)까지 한사대(韓社大) 부속(附屬) 농학교(聾學校) 재학생(在學生) 207명(名)(초등(初等) 138명(名), 중등(中等) 47명(名), 고등(高等) 22명(名)), 즉(卽) 남(男) 135명(名), 여(女) 72명(名)을 대상(對象)으로 문진(問診)을 통(通)한 사회의학적(社會醫學的) 배경조사(背景調査)와 특수교육연구소(特殊敎育硏究所) 방음실(防音室)에서 AS-105형(型) 진단용(診斷用) TRIO 청력측정기(聽力測定器)에 의(依)한 청력검사결과(聽力檢査結果), 다음과 같은 성적(成績)을 얻었으므로 이에 보고(報告)하는 바이다. (1) 의무교육(義務敎育)은 초등교육(初等敎育)의 취학률(就學率)도 정상아(正常兒)에 있어서와 달리 난청출현율(難聽出現率)에 비례(比例)하여 고도난청아(高度難聽兒)에 있어서는 여자(女子)쪽이 현저(顯著)히 낮은 경향(傾向)이었고, 상분학교(上粉學校)(중(中),고(高))에 진학(進學)할수록 더욱 심(甚)한 격차(隔差)를 보였다. (2) 적령기(適齡期)(초등(初等) 만(滿) 6세(歲), 중등(中等) 12세(歲), 고등(高等) 15세(歲))에 입학(入學)한 학생(學生)은 11.3%, 학령기(學齡期)(초(初) 6세(歲)${\sim}11$세(歲), 중(中)12(세)歲${\sim}14$(세)歲, 고(高)15세(歲)${\sim}17$세(歲))에 재학(在學)하고 있는 학생(學生)은 45.9% (남(男) 43.7%, 여(女) 50%)이였다. 이러한 현상(現象)은 현장교육(現場敎育)이 기대(期待)에 부응(副應)치 못하며 장해아동(障害兒童)을 기피(忌避)하고 임상적(臨床的)으로만 청력(聽力)을 개선(改善)할려는 부모(父母)의 학력(學歷), 직업(職業)(농업(農業)과 판매업(販賣業)이 50.8%)및 심리적(心理的)인 현상(現象)과 대부분(大部分)의 이비과병원(耳鼻科病院)에 잔존청력(殘存聽力)을 정확(正確)히 판단(判斷)할 수 있는 유아청력검사(幼兒聽力檢査) 시설(施設)이 없으므로 조기발견(早期發見)과 대책(對策)을 강구(講究)치 않는데 기인(基因)된다고 사료(思料)된다. (3) 실청(失聽)이 될수 있었던 원인(原因)은 대개(大槪) 선천성(先天性) 23.6%(유전성(遺傳性) 13.5%, 임신시이상(姙娠時異常) 10.1%), 후천성(後天性)47.9%(경련(痙攣) 11.6%, 홍역(紅疫) 7.7%, 열병(熱病) 7.7%) 약물중독(藥物中毒) 3.4%, 뇌막염(腦膜炎) 2.4%, 뇌염(腦炎) 1.5%, 기타(其他) 31.3%), 불명(不明) 28.5%인 경향(傾向)이었다.

The survey was performed through interview with their parents and testing by diagnostic audio-meter (TRIO, AS 105 type) at soundproof room from March 10, to November 28, 1973. The results obtained were as follows. 1) The attendance rate of the compulsory primary school was markedly lower tendency in female than male according to directly proportional to prevalence rate of deafness among them. If was showed the deeper gap in the more superior school (middle and high school). 2) Who entered at the suitable age to each school (six years old to primary school, 12 years to middle and 15 years to high) was 11.3%. And who were enrolled in school age to each school (6-11 years for primary. 12-14 years for middle and 15-17 years for high) was 45.9% (43.7% in male, 50.0% in female). 3) As causative disease, congenital case, were 23.6% included of 13.5% of heredity and 10.1% of troubles during pregnancy; the total acquired cases were 47.9%, it was classified as 11.6% of convulsion from any other diseases, 7.7% of measles, 7.7% of other febrile diseases, 3.4% of drug (the most of streptomycin) intoxication, 2.4% of meningitis, 1.5% of epidemic encephalitis and 31.3% of other diseases; and unknown cases were 28.5%. 4) 31.4% of who included congenital cases lost their hearing within six months old, 11.6% in 6-11 months. 9.7% in 1-2 years old and 14.0% in 2-3years old. Consequently we obtained that the most cases 90.0% were lost their hearing within 3 years after birth. 5) According to qualities of hearing leases the most of cases were perceptive, 197(97.5%), only two cases were conductive, and eight cases were mixed. 6) The status of residual hearing according to average grade of hearing loss. $B(=\frac{a+2b+c}{4}$ as table 13) were as follows. Two cases were normal (one was mute and another was severe speach disorder). Ten cases, moderate. Moderately severe cases were 40 (19.3%). Severe cases, 38(18.4%). Scale out, profound cases, 48 (23.3%). And impossible testing cases because that were infantile or had some mental disorder were 69 (33.3%). 7) The using rate of hearing aides was only 12.0%. Among them who had some more residual hearing and could showed hearing effect with hearing aide have used more many proportionary but who were difficult to expect that effect were rare.

This paper presents the results of a survey for the causes of sensori-neural hearing impairment in Korea, The subjects were 1,676 children of total 2,928 enrolled in 16 Deaf Schools; two schools in each area of Seoul, Busan, Kyoungbook, Kyoungnam, Kyounggi and Chunbug, and each one in Chungnam, Chungbug, Chunnam and Jaeju. The data were collected by questionaire with 28 items distributed to their parents. The filling in the check lists were performed by their class teachers, interviewer, for 18 months from September, 1975 to february, 1976. The questionable or missed problems were reaffirmed. The results obtained were as follows. Most of the reasons, 78.5% were acquired characters that could be developed during pregnant period, the time of delivery and the time of after birth. The pure hereditary reasons except the cases complexed with one or two were only 11.3%. Those who could not be defined with any reasons were 10.2%. Among the acquired causes, 5.8% of total subjects were developed for pregnancy: 3.3%, during delivery; and 69.7%, after birth. In the pregnant period, the drug intoxications were 2.4% of total subjects, several diseases such as influenja, bleeding, surgical operation, venereal diseases and rubella etc. were about one percent, and the accompanied with some symptoms of pregnancy intoxication and traumatic events were 2.4%, During time, the cases with delayed rhythmical pain were 16 persons, the immaturities were 11, the asphyxial cases were nine, the errors of forceps delivery were seven, the cases of low body weight inspite of full term were four, the cases with cesarian section were three, the head injuries were two, and the accompanied with three kinds of above reasons were three. During after birth, the cases with acute communicable diseases were 35.4% of total subjects, the fever unknown origin were 16.1%, the chronic otitis media were 3.7%, the meningitis were 3.5%, the gastric and nutritional diseases were 3.5%, the drug intoxications were 4.8%, the blood diseases were 0.3% and the other causes were 2.2%. Here by acute communicable diseases, some importants were measle, 10.1% of total subjects; meningitis, 7.3%; convulsion with some reasons, 4.9%; poliomyelitis. 3.2%; encephalitis, 2.4%; and mumps, rubella, pertusis, scarlet fever, and small pox were somewhat played a role in. Among 59 cases with train diseases, 53 were concussion by the accidents, such as traffic and falling or sliping down etc., the cerebral paralysis and hydrocephalus were two, respectively. And the blood diseases were severe newjaundice in all five cases. If we were summarized with the above mentioned, most of the hearing impairments were introduced by the combined reasons with familial or hereditary factors and the acquired, than by a simple disease. Among the congenital or hereditary hearing impairments classified to now a day, we suppose that the many cases with the acquired causes during pregnancy, delivery and after birth were complexed. Subsequently, the maternal and child health should be more and more developed in our country, also.

The results obtained were summerized as follows. According to our criteria as table 3, the rates of the profound, the severe and the moderate who required the appropriate hearing aids were 0.02%, 0.03% and 0.14% respectively:-the cumulative percentage was 0.197. When the marginal, 0.23% should be included the cumulative rate was 0.41%. But there was no-significance by sex and school classes. If we will make the special classes for them one class would be estimated out of 10,000 persons when a class is formed with about 15 persons. Otherwise when we examined that according to each ear of persons, the rates of the profound, the severe and the moderate were 0.17%, 0.22% and 0.33% respectively and their cumulative percentage wag 0.72. There was no significance also by sex and age. By the way, the rate of hearing disturbance in urban high school students tended to lower than rural. And the perceptive disturbance was higher than rural in rate. The conductive disturbance tended to oppose in comparison with the above.

The purpose of this study was to examine the changes of acoustic characteristics of hearing impaired children's sound and speech before and after offering auditory feedback. which used a hearing aid and a cochlear implant, and to find out the effects of auditory feedback on the changes. The participants were composed of 10 normal children, 10 children with a hearing aid on, and 10 children with a cochlear implant on. The conditions for the selection of participants were limited to children with no physical handicaps including hearing impairment, children .who lost hearing before language acquisition, children whose hearing loss was over 90 dB, and children who depended entirely on a hearing aid. Their age range was from 9 to 10 years old. In order to find out the changes of acoustic characteristics of hearing impaired children's sound and a cochlear implant made by auditory feedback., the study went through F1, F2, F2-F1 analyses in the sounds of /ah, uh, ih/ vowels through CSL, and compared them with a F0 analysis in the first and second syllabus speeches. The mean differences of F0, F1, F2, F2-F1, before and after putting on a hearing aid and a cochlear implant, were verified by means of a paired t-test. To compare the means of F0, F1, F2, F2-F1 between the group of a hearing aid and the group of a cochlear implant, a t-test was conducted. The results of this study were as follows; First, auditory feedback through the use of a hearing aid and a cochlear implant improves artimlation problem in the sounds of /ah, uh, ih/ vowels created by hearing impaired children. That is, after the auditory feedback, the location of tongue was modified by putting lower or bad<.ward their tongue for /ah/ vowel, higher or more backward for /uh/ vowel, and higher or more forward for /ih/ vowel. Since this phenomenon is considered to improve the articulation of well problem through the modification of the location of tongue by offering auditory feedback, there can be direct correlations between auditory feedback and acoustic characteristics of sound. Second, auditory feedback through the use of a hearing aid and a cochlear implant improves articulation problem in the healing impaired children's first and second syllabus speeches. That is, since the fact that the pitch gets lower means the improvement of artimlation problem, there can be direct correlations between auditory feedback and acoustic characteristics of speech. Finally, the types of auditory assistants offering auditory feedback do not influence the improvement of articulation problem in the sound and speech. That is, since no differences are shown between the group of a hearing aid and the group of a cochlear implant offering auditory feedback, the existence of auditory feedback can be more important for the improvement.

인공와우의 매핑은 소아 인공와우 프로그램에서 필수적인 부분으로 아동이 인공와우로부터 받는 도움의 정도를 평가함에 있어 중요한 역할을 담당한다. 본 연구는 Nucleus 다채널 인공와우 시스템을 이식 받은 아동 15명의 전기 자극 역치와 역동범위를 측정하여 그 변화를 분석하였다. 대상아동의 연령범위는 최소 2세 9개월에서 최대 10세 11개월이었으며, 각 전극의 전기 자극 역치와 최대 쾌청치는 첫 자극으로부터 3, 6,12, 18, 24, 36개월째에 측정하였다. 대상아동 15명 중 13명의 전기 자극 역치에서, 그리고 14명의 역동범위에서 통계적으로 유의미한 변화를 보였으며 3개월에서 12개월 사이에 비교적 많은 변화를 나타냈다. 이와 같은 결과는 인공와우이식 아동이 일상생활에서 인공와우로부터 최대한의 도움을 받기 위해서는 특히 이 기간에 더 많은 회기의 매핑이 필요함을 의미한다. Mapping of cochlear implant s is an essential part of the paediatric program. It is necessary to assess children over time to determine the long - term benefit s. T he purpose of this study was to measure changes in electrical thresholds, dynamic range of children with cochlear implant s. Fifteen children with prelingual onset s of deafness were implanted with the Nucleus multichannel cochlear prosthesis. T hey ranged in age from 2 year s 9 months to 10 year s 11 months. Electrical thresholds and comfortable levels for each electrode used in the children were measured at 3, 6, 12, 18, 24, and 36 months after initial stimulation. T hirteen of the 15 children had statistically significant changes over time in their electrical thresholds and 14 of the 15 children, in dynamic range. The changes occurred between 3 months and 12 months considerably . The result of this study underlines the necessity for more frequent programming sessions for 12 months from the fir st stimulation to optimize hearing in everyday life.
