청각의 중요성은 새잠스럽게 말활 필요도 없고 농아가 말못하는 것은 누구나 다 알 수 있는 사실입니다. 그러나 음을 하나하나 습득하고 단어를 하나하나 반복하면서 언어습득을 시작하는 유년기에 있어서 청각은 더욱 독특한 역활을 합니다. 조국에 돌아와서 일하기 시작한지 일년이 조금 넘었으나 최초부터 우리 연구소에 찾아오는 어린이가 구주제국보다 훨씬 연소하고 또 수가 훨씬 많은 데 놀랐습니다. 그 중 대다수가 조음장애라든가 언어지연입니다. 더욱 놀라운 점은 이러한 장애가 정상지능의 어린이에게 많은 것입니다. 일반상식으로 어휘력과 발표력이 부족한 어린이들은 정신지체아와 혼동하게 됩니다. 연구소에 진단받으러 오는 어린이들을 체계적으로 청각 검사를 한 결과를 슬라이드를 통해서 말씀드리겠습나다. 검사받은 어린이 중 50-60%가 청각에 이상이 있는 것이 발견되었습니다. 동반한 어머니들은 너무나 놀라서 "우리 아이는 검사를 받았어요! 모두 정상이라고 그랬어요" 이 엄마 말씀도 정당하고 전검사도 정당활 것입니다. 그러나 이러한 어린이들의 문제는 특수합니다. 즉 경도난청에다 또 일시적 난청이기 때문에 명시에 생활하는 데는 큰 지장이 없고 때에 따라서는 청각이 거의 완전히 회복되고 또 몇 주후에 감기가 들거나 하면 다시 난청이 되는 것입니다. 이러한 난청문제가 일년에 3-4번씩 반복되어 어린이가 만 3-4세가 되면 약 1년간 청확한 음을 청취못한 셈이 됩니다. 조석에 기온차가 대단한 계절, 난방의 발달로 인하여 실내는 영상 24도이고 문 한겹만 열고 나가면 영하 10도 그 차이는 34도, 거리로 나가면 일산화탄소를 뿜고 쾌주 하는 차량, 버스나 트럭에셔 나오는 연기는 키가 작은 어린이 코속으로 직통하고 에어컨 시스댐으로 난방.냉방하는 지하상가, 백화점, 지하철 기타 대건물에는 바이러스 만연의 적절한 곳이 됩니다. 생리적 저항력이 없는 어린이들은 이러한 공해와 생활조건의 제일희생자가 되는 것입니다. 엄마들이 "얘는 감기, 비염, 편도선을 달고 삽니다...." "얘는 코감기, 목감기 번갈아 가면서 하도 앓고 있어서 양약율 중지하고 현재 한약을 먹고 있습니다." 이러한 역경은 극복할 수 있는가\ulcorner 질병의 메카니즘은 어떻게 작용되는가\ulcorner 등등을 육미회 센타에서 체험한 사례를 가지고 말씀드리고자 합니다.

Infection with enterovirus (EV) 71 is usually associated with hand-foot-and-mouth disease and herpangina. The most frequent neurologic complication is brainstem encephalitis. A 30-month-old boy visited the pediatric emergency department with fever, lethargy, and abnormal eye contact. His mental status was slightly drowsy. On hospitalization day 2, the patient experienced respiratory arrest with apnea. Brain magnetic resonance imaging revealed bilateral symmetric T2-high signal lesions without enhancement in the posterior aspect of the brainstem and left medial temporal lobe. Electroencephalography was indicative of diffuse cerebral dysfunction with diffuse high amplitude and irregular delta activities. He underwent a gene study and was diagnosed with myoclonic epilepsy with ragged red fibers syndrome. We report a case of EV 71 brainstem encephalitis by polymerase chain reaction for nasopharyngeal aspirates and feces with rapid progression within one day of fever without the manifestation of throat and skin lesions because of his underlying mitochondrial disease.

The purpose of this study was to develop and verify the effectiveness of consultant development program enhancing 'authentic parental competence' of the mothers with preschool and school-age children. The objects of this study were 14 mothers with preschool and school-age children. In order to examine the changes of the mother's parental competence, t-test and qualitative analysis on in-depth interviews were conducted. The results of this study were as follows. First, this program had a positive effect on all the sub-factors of mother's 'authentic parental competence'. Second, mothers mentioned that they changed their parenting competence(change of parenting knowledge, beginning of reflective attitude on their parental role), self-system competence(understanding and respective attitude for the mother herself, self-awareness as a spouse, sweet glances and warm understanding as a parent), social competence(sympathetic understanding of her acquaintances, attempt a role as consultant) after this program. Based on these results, the implications and limitations were also discussed.

Previous studies have provided important findings on children's speech production development. They have revealed that essentially all aspects of children's speech shift toward adult-like characteristics over time. Nevertheless, few studies have examined the perceptual aspects of children's speech tokens, as perceived by naive adult listeners. To fill the gap between children's production and adults' perception, we conducted cross-sectional perceptual studies of monosyllabic words produced by children aged two to six years. Monosyllabic words in the consonant-vowel-consonant form were extracted from children's speech samples and presented aurally to five listener groups (20 listeners in total). Generally, the agreement rate between children's production of target words and adult listeners' responses increases with age. The perceptual responses to tokens produced by two-year old children induced the largest discrepancies and the responses to words produced by six years olds agreed the most. Further analyses were conducted to identify the sources of disagreement, including the types of segments and syllable structure. This study makes an important contribution to our understanding of the development and perception of children's speech across age groups.

Background: Closure of the ductus arteriosus is often delayed in premature infants, which creates a hemodynamically significant left to right shunt that exerts an adverse effect on the normal development and growth of these babies. We reviewed out experience on surgical closure of patent ductus arteriosus via axillary minithoracotomy in premature infants. Material and Method: From April 2002 to October 2006, 20 premature infants whose gestation was under 37 weeks underwent surgical closure of patent ductus arteriosus as a result of complications or contra-indications for the use of indomethacin. Their mean gestational age was 28.8+3.4 weeks, ranging from 25+3 to 34+6 weeks, and the average age at operation was $15.6{\pm}6.3$ days. The mean body weight at operation was $1,174{\pm}416\;g$, ranging from 680 to 2,100g; 16 infants were under 1,500 and 9 infants were under 1,000 g. The procedures were performed in the newborn intensive care unit via $2{\sim}3\;cm$ long axillary minithoracotomy with the infant in the lateral position with left arm abduction. The mean size of the patent ductus arteriosus was $3.8{\pm}0.3\;mm$. For the most part, the ductus was closed with clips; 2 infants in whom the ductus was ruptured while dissection was being performed underwent ductal division. Result: Ten of twelve infants who had been ventilator dependent preoperatively could be successfully weaned from the ventilator at a mean duration of 9.7 days after the operation. There was no procedure-related complication or death. Two infants eventually died of the conditions not related to the operation; one from sepsis at postoperative 131 days and the other from pneumonia at postoperative 41 days, respectively. Conclusion: Surgical closure of the patent ductus arteriosus improved the hemodynamic instability and so promoted the successful growth and normal development of premature infants. Considering the low surgical risk along with the reduced invasiveness, early and aggressive surgical intervention is highly recommended.
