As Waterpower Generation generates electricity using the difference of altitude of water, also let the turbine revolves through water pipe, at this time the revolving turbine causes exceedingly huge noise. Accordingly, not only those workers in the hydraulic turbine dynamo room are suffering the difficulties in mutual communication, but also those workers in the adjacent office are enduring the obstruction to the business due to the noise. Particularly, since the dynamo room located on the middle between the hydraulic turbine dynamo and the office had been architecturally concluded, not only with all of the reflection materials, but also holds a great volume of 22,800㎥, it functions rather to amplify the Noise that occurs during the operation time of the hydraulic turbine dynamo. Accordingly, after actually measure the architectural acoustic performance on the object of the hydraulic turbine dynamo room, and compare with the forecasted value through a computer simulation, thence this Research has verified the authenticity of the simulation. Based on such authenticity of the forecasting, this Study would intend to propose the architectural acoustic element likely as restraint the amplification of dynamo noise, reduction the noise travelling to the adjacent room, enable to maintain the optimum acoustic condition.

본 연구의 목적은 어린이집 평가인증 제도에 대한 보육교사의 인식과 실태를 분석하여 평가인증 제도의 효율적인 수행과 성공적인 정착을 위한 방안을 모색하는 데 있다. 어린이집 평가인증 제도에 대한 보육교사의 인식과 실태를 분석하기 위한 설문지를 개발한 후 연구자료를 수집하였다. 개발된 설문지는 평가인증 제도에 대한 보육교사의 인식, 평가인증 준비과정에 대한 보육교사의 인식 및 실태, 평가인증 지표(7개 영역)에 대한 보육교사의 인식, 평가인증 사후관리에 대한 보육교사의 인식의 4개 영역으로 구분하여 총 36문항으로 구성하였다. 연구대상은 S시에 소재한 어린이집 중 2005년 3월부터 2011년 6월까지 평가인증을 통과한 어린이집의 보육교사 154명이었으며, 수집된 자료는 χ2-검증을 실시하여 분석하였다. 연구결과, 평가인증 제도에 대한 인식, 평가인증 준비과정에 대한 인식 및 실태, 평가인증 지표(7개 영역)에 대한 인식, 평가인증 사후관리에 대한 인식은 보육교사가 재직하고 있는 어린이집 유형에 따라 부분적으로 유의한 차이가 있는 것으로 나타났다. The purpose of this study was to analyze the status and childcare teachers' awareness of the Childcare Center Accreditation System to implement and settle down the system successfully. A questionnaire was developed based on prior literature, research and arrangements with professors and childcare teachers. The questionnaire is composed of 4 items of 36 questions related to 'general awareness of the Childcare Center Accreditation System', 'the preparatory process of the Childcare Center Accreditation System','7 indicators of the Childcare Center Accreditation System', and 'post management of the Childcare Center Accreditation System'. The Subjects used in this study were 154 childcare teachers who work for childcare center passed the Accreditation System from March, 2005 to June, 2011 in S province. Data analysis was conducted by χ2-test. The results of this study indicated that there were partially significant differences among childcare teachers according to the types of childcare center.

선천성 횡격막 내장탈출은 드문 질환으로 산전 초음파로 횡격막 헤르니아와 감별하는 것은 쉽지 않다. 선천성 횡격막 내장탈출과 횡격막 헤르니아의 예후가 다르고 수술적 접근 방식이 다를 수 있어 정확한 감별 진단이 필요하다. 저자들은 산전 초음파 검사에서 선천성 횡격막 헤르니아로 진단되었으나 수술 시에 선천성 횡격막 내장탈출로 진단된 두 증례의 후향적 분석을 통하여 비록 출생 직후의 단순 흉부 사진으로는 두 질환의 감별 진단이 어려웠으나 연속적인 단순흉부사진에서 뚜렷하게 드러나는 병변 측 횡격막을 확인하는 경험을 하였다. 따라서 산전 초음파 검사에서 횡격막 헤르니아로 진단되었다 하더라도 출생 이후에 촬영한 연속적인 단순흉부사진의 주의 깊은 판독을 통한 재평가를 강조하고자 한다. Congenital diaphragmatic eventration is the abnormal elevation of the diaphragm into the thoracic cavity. Sometimes, it is not easy to differentiate congenital diaphragmatic eventration from diaphragmatic hernia by either prenatal sonography or postnatal chest radiography. However, differential diagnosis of both diseases is practical because of different prognosis and surgical approaches. Careful interpretation of postnatal serial chest X-rays is mandatory to differentiate between both diseases. We report two neonates with congenital diaphragmatic eventration of left diaphragm that initially misdiagnosed as diaphragmatic hernia by prenatal sonography and postnatal chest radiography.

This clinical and histopatholgical study was performed with 149 cases of acquired melanocyticnevi, which were obtained as surgical specimens from 1975 to 1985 at Depa.rtment of Clinical Pathology, Seoul Red Cross Hopital. The results were as follows: 1) Histologic subdivision of melanocytic nevus into junctional(,J), IJC, compound (C,), ICI, and intradermal(I) is used. IJC is a lesion in an intermediate state between ,junctional and compound nevus, and ICI, between compound and intradermal nevus. 2) The age distribution of the excisional melanocytic nevus peaks during the third decade of life, with 47% of patients between 21 40 year old of age. 3) Of l49 specimens with excisional melanocytic nevus, the number of junctional, IJC, compound, ICI and intradermal nevus were 17, 4, 21, 32 and 75 in each group And so, it is likely that evolution of the melanocytic nevus have an increased opportunity for surgical excision. 4) Among the 17 cases of junctional nevus, one case is found in 5th and the other one in 7th decade. 5) In distvibution of melanocytic nevus, head including face is the most common site among the body area and then trunk, neck, lower and upper extremity in decreasing orders.
