The acoustical properties of the chamber at the Department of Physics, Sung Kyun Kwan University are investigated. By using the least square method based on pressure inverse law each reference sound pressure level is determined. The free field data are collected at both outdoor and indoor measurements. The deviations from the free field condition show that a reference sound pressure level plays a critical role in evaluating the performance of anechoic chamber. The cutoff frequency of the anechoic chamber is found to be in the range of 150Hz-170Hz.

연구배경 및 방법: 골형성부전증은 비교적 희귀한 유전병으로 교원질 대사 장애로 인한 골의 취약성과 다발성 골절 및 척추측만증 등을 특징으로 한다. 유전방식과 표현형의 발현 정도에 따라 다양한 임상 양상을 보이며, 임상적 중증도에 따라 4가지 형태로 분류된다. 지금까지 국내 보고는 분만과정이나 태아 진찰시 골격이상으로 발견된 증례보고가 주였다. 저자들은 비교적 경미한 임상 양상을 보이는 예를 포함한 다수의 골형성부전증 환자들의 전반적인 임상적 특징에 대해 보고하는 바이다. 결과: 2001년 6월부터 2003년 2월까지 골형성부전증으로 진단받은 6 가계, 10예를 대상으로 하였다. 평균 나이는 27.3(5∼56)세였고 소아가 2예였다. 모두 상염색체 우성으로 유전되었으며, 제 I형이 4예, 제 III형이 4예, 그리고 제 IV형이 2예였다. 전 예에서 다수의 골절 경험이 있었고, 골밀도 저하와 골피질 두께 감소 소견이 관찰되었다. 전신의 평균 골밀도는 0.690(0.421∼1.039) g/cm²였다. 골형성지표로 측정된 sAlk는 소아의 경우만 증가되어 있었고, 골흡수지표로 측정된 uDPD의 평균치는 12.9(4.4∼36.3) nM/mM Cr으로 증가된 소견을 보였다. mobility score는 대부분 3,4단계에 속해 있었다. 중증형일수록 진단 시의 mobility score가 낮은 경향을 보였다. 결론: 한국인 골형성부전증 환자의 임상적 특징을 살펴본 결과 기존의 보고된 II형 외에도 I, III, IV형이 다양하게 존재함을 알 수 있었으며, 모든 예에서 상염색체 우성으로 유전됨을 확인할 수 있었다. 또한 모든 예에서 증가된 골흡수로 인한 골밀도 저하와 골절을 확인할 수 있었다. Osteogenesis Imperfecta (OI) is a relatively rare hereditary disease, which is characterized by multiple bone fractures and spine scoliosis, due to the fragility of bone, and is often associated with blue sclerae, deafness and dentinogenesis imperfecta. Four types of OI can be distinguished, according to the clinical findings. Although mutations affecting type I collagen are responsible for the disease in most patients, the mechanism by which the genetic defects cause abnormal bone development remains to be fully understood. Here, the clinical characteristics of 10 OI patient cases are reported, with a review of the literature. All the cases, including 4 type I, 4 type III and 2 type IV, inherited OI as an autosomal dominant trait. All the subjects had multiple old fractures and decreased bone densities. In this study, the biochemical marker of bone formation, serum alkaline phosphatase, was found to be increased only in the pediatric OI patients, while the biochemical marker of bone resorption, urinary deoxypyridinoline, was increased in all cases. The mobility score was found to correlate with the severity of the type on diagnosis (J Kor Soc Endocrinol 18:496∼503, 2003).

Back ground : The becoming older in age society which is caused by with increase of average length of life shows the continuous increase of the old person population. Reasoning with chronic retrogression characteristic disease or the dementia which is caused by also the same spirit nervous school register disease is increasing together. But still the research against the system function evaluation regarding an old person disease or epidemiology investigation insufficient from our country. The research which it sees led the old person probably is, evaluation and the what kind of should have given an effect, it examined and the research to begin it enforced. Methods : Duration to the object September from to October until 2005 the Young-Cheon city Sinlyung in village, Ha-Yang a town visited and sixty clients. All over 60 years of age, were the objects of tests for cognition function using the Mini Mental Status Examination-Korea (MMSE-K). Results: 1)Signify were closely correlated in MMSE-K scores accounted by the public characteristic the same educational level, age and sex. 2)Educational levels were closely correlated with MMSE-K scores. More over higher a confuncianism more all any other illiteracy. 3)Men received higher MMSE-K scores than women, especially in the noneducated group and the elementary school failure group. In conclusion, readjust ments of MMSE-K scores for demo graphic variables. 1. 배 경 평균수명의 증가로 인한 고령화 사회는 노인 인구의 계속족인 증가를 나타내고 이로 인한 만성퇴행성 질환이나 치매와 같은 정신 신경학적 질환도 함께 증가하고 있다. 그러나 우리나라에서는 아직 노인질환에 대한 체계적인 여러 기능 평가에 대한 연구나 역학 조사가 미흡하다고 할 수 있다. 따라서 본 연구는 노인 인지도 평가를 통해 어떤 점이 영향을 미치는지에 대해 알아보고자 본 연구를 시행하였다. 2. 방 법 2005년 9월 초에서 10월 말까지 영천시 신령면, 하양읍을 방문하여 60세 이상의 노인 각 60명을 대상으로 인지기능의 검사로서 MMSE-K를 측정하여 비교, 분석하였다. 3. 결 과 1) 연령, 성별, 교육 수준 등 일반적 특성인 변인들에 의해 MMSE-K 점수 변이는 밀접한 상관관계를 나타내었다. 2) 교육 수준은 MMSE-K 점수와 밀접한 상관관계를 갖고 있으며 유학이 무학보다 유의성이 높았다. 3) 남자는 여자에 비해 MMSE-K 점수가 의미있게 높았으나 이 차이는 주로 무학 등 저학력 남녀 노인 간의 차이에서 나타난 것이며. 이는 남, 녀 간의 인지기능 점수의 차이가 생물학적인 근거에 의해 생기는 것이 아니라는 것을 말한다.

Conflicts between individuals are quite natural and they can act as an positive contributing factor not only to the development of an individual but also to the organization to which one belongs. But too much conflicts will always induce dissatisfaction and stresses, which will be destructive and harmful to all of them, and that is why we are always tying to seek(find) out the causes for the origination of conflicts and remedies to cope with them effectively. The present study, as the first one in a series of studies which our researchers contemplate executing, was designed to develop a measure of job satisfaction for dental laboratory technicians. One job satisfaction measure and two job satisfaction related measures, one for faithfulness for the job and the other for environmental characteristics of dental laboratory were newly developed. The newly developed measures were comprised of a total of 38 items, which were each 12 items for job satisfaction and faithfulness for the job and 14 items for environmental characteristics of dental laboratory With the aid of factor analysis for principal components and categorization of items by panel of professionals, items of each measure were grouped into 2-4 subscales. Contribution to internal consistency was the fina) criterion for an item's inclusion in a subscale. Internal consistency reliability of each item was attested through the statistical analysis on the data obtained from 55 structured questionnaires. Reliability of internal consistency of subscales in each measure of job satisfaction and faithfulness for the job ranged from 0.74 to 0.79 and 0.90-0.91 respectively. The result from this research came to draw the following conclusions. 1. Validity and internal consistency reliability of all the items of each measure was attested. 2. The newly developed measure of job satisfaction was found to be appropriate for (measuring the degree of job satisfaction of) dental technicians, as well as for (other) dental office personnels.

Back Ground : Hypothermia is a condition that can lead to serious complications and even to death in newborn. Although the temperature control is essential in neonatal care, it is often neglected during urgent transfer from local private hospitals. The purpose of this study is to evaluate the incidence and clinical outcomes of transfer induced neonatal hypothermia. Subjects and Method : In this retrospective study, subject is limited to transferred outborn babies with age less than 27 hours from June 1996 to May 1999. A total of 3,086 patients were admitted in NICU during the study period and inborn and outborn babies were 1,743(56%) and 1,343(44%) respectively. Among the 1,343 outborn babies, 212 babies were transferred from the private hospital within 24 hours of birth and were eligible for the study. Rectal temperature on arrival, transfer time, birth weight, gestational age, initial arterial gas study, and clinical outcome were compared. Statistical analysis has been done with chi-sqaure test and multiple logistic regression analysis. Results : There were 84 cases(39.6%) hypothermia(<36℃) among the 212 babies and the rate of hypothermia in transfered babies have not decreased over the study period. There were significantly more hypothermia in lower gestational age (less than 28 weeks) and lower birth weight (less than 2,000gm) caused hypothermia significantly more than normal gestational age or normal range of birth weight. And time interval (less than 12 hour) from birth to arrival at emergency department was also significant factor in hypothermia. The mortality rate was three fold higher in hypothermia than normothermic or hyperthermic babies. Conclusion: This study shows that hypothermia during neonate transportation is a major cause of neonatal mortality and morbidity in prehopital care. Body temperature control during transport of neonates under 24 hours of age should be emphasized for the better outcome of treatment.

鄭海駿,尹錫天 충남대학교 공업교육연구소 1978 論文集 Vol.1 No.1

As the methods of calculating deflection of structures, various ordinary differential equations, that is, the Unit load method, the Moment area method, and Castigliano's theorm have been used. But here the anothers applied Laplace tranform to in the deflection analyses of the propped cantilever beams. The result shows the deflections calculated by Laplace transform are the same values those from ordinary solutions, and are better than the others in efficiency.
