고려대학교 흉부외과에서는 심실보조장치 이식에서 흉골 재절개(re-sternotomy)에 따른 합병증과 사망률을 감소시키기 위하여 우측 개흉을 이용한 독자적인 수술법을 개발하였다 (KU technique). 다양한 동물모델과 사체실험 및 임상적용을 통해 안정성과 유용성을 확인하였으며, 향후 좌심 및 양심보조장치 이식에서 표준기법의 하나로 제안하고자 한다. We have developed a new surgical technique (KU technique) of right thoracotomy for cannulation of ventricular assist devices, which can lessen potential morbidity and morta1ity from re-sternotomy. The technique has been proved to be safe and efficient in various animal models, preclinical cadaver fitting test, and human application. We would like suggest KU technique as a part of standard in implantation of left ventricular or hi-ventricular assist devices.

공장계열과 생활계열 하수슬러지의 탈수특성 비교

황선진,엄형춘 경희대학교 환경연구소 2002 環境硏究 論文集 Vol.11 No.-

In this study the dewaterablity properties of industrial wastewater sludge and that of municipal wastewater sludge were compared by pre-treatment of wastewater sludge. The sludge of Kyunggi-Do A-wastewater treatment plant was used. of industrial wastewater sludge was 2.6% and TS of municipal sludge was 2%. And VS of industrial wastewater sludge was 57.2% and VS of municipal sludge was 62.4%. In case of heavy metal concentration, industrial wastewater sludge was three times municipal wastewater sludge. For compare with dewaterability of sludge, ECP(exocellular polymers) concentration of bulk solution was measured and CST(capillary suction time) and settlablility was tested. ECP concentration of industrial wastewater's bulk solution was higher than that of municipal wastewater's bulk solution. For all pre-treatment, dewaterablity of industrial wastewater sludge was better than that of municipal wastewater sludge by CST test. The improvement of dewaterablity by acid treatment with H202 was more remarkable than other pre-treatment.

어머니의 취업이 양육태도 및 아동의 성격에 미치는 영향

김신형,나귀옥 순천향대학교 1994 논문집 Vol.17 No.3

The aim of this study is to analyze the influences of the mother's employment on her child rearing attitude and her children's personality. And the subdivisicnal aim is to provide aids for mothers who are at work about desirable child education by investigating a) the influence of mother's employment status on her child rearing attitude and her children's personality, b) the realtionship between mother's child rearing attitude perceived by children and children's personality, c) the realtionship between mother's recognition of her employment and her children's personality. In order to analyze above tasks I randomly selected 180 persons who are 60 sixth grade students and their mothers at work and 60 sixth grade students whose mothers are not at work respectively at elementary schools in Cheonan. One-way analysis of variance was employed using mothers employment status as independent variable and child rearing attitude scores observed by children and children'personality as dependent variables. And I tested the relationship among mother's child rearing attitude, mother's recognition of her employment, and her children's personality by computing Pearson product moment correlation coefficient. The results of this analysis are summed up as follows. Mother's employment influenced children's personality partly but not entirely and there was no significant difference in mother's child rearing attitude according to mother's employment status. Also irrespective of mother's employment status children who are conscious of their mother's child rearing attitude as receptive are shown to have more self-control and responsibility and children whose mother experienced difficuilties in childbirth owing to employment are conscious of much more achievement pressure. In short, because children's personality development is much more influenced by mother's child rearing attitude than by mother's employment status, mothers at work should have desirable nurturing attitude and by qualitatively enhancing the time which mother interacts with children.

한국인에게서 그레이브스병 약물치료의 적정기간

이형숙,이동훈,정희선,이종우,김정은,신승수,정윤석,이관우,김현만 대한내분비학회 2003 Endocrinology and metabolism Vol.18 No.1

연구배경: 그레이브스병의 치료에는 항갑상선제, 수술 및 방사성 요오드법이 선택되어 사용되고 있다. 이중 항갑상선제는 가장 많이 선호되고 있으나 낮은 관해율과 높은 재발율로 장기간 치료기간이 요구된다. 저자들은 그레이브스병 환자에게서, 선택되는 치료법의 선호도와 각 치료법의 관해율을 조사하고자 본 연구를 시행하였다. 또한 본 연구에서는 항갑선제 치료의 적정기간을 평가하고자 하였다. 방법: 아주대학교병원에 내원한 환자 중 1년 이상 추적관찰이 가능한 205명의 그레이브스병 환자를 대상으로 조사하였다. 항갑상제군, 수술군 및 방사성 요오드군은 각각 170명, 29명 그리고 6명이었다. ROC curve를 이용하여 약물치료의 예후예측인자를 분석하였다. 결과: 1) 그레이브스병 환자의 치료 방법의 선택은 항갑상선제군, 수술군 및 방사성 요오드군 각각 170명(83.0%), 29명(14.1%) 그리고 6명(2.9%)으로 항갑상선제 치료가 가장 선호되었다. 2) 그레이브스병의 관해율은 항갑상선제군, 수술군 및 방사성 요오드군에서 각각 60.0%(102/170명), 96.5%(28/29명) 그리고 83.0%(5/6명)으로 수술군이 가장 높았다. 3) ROC curve의 AUC는 치료기간과 진단시 TBII가 각각 0.709 및 0.648이었고 적절한 약물투여 추적 관찰기간은 26개월이었다. 결론: 그레이브스병의 일차 치료법으로는 항갑상선제가 선호되고 있으나 수술 및 방사성 요오드 치료군에 비해 상대적으로 낮은 관해율을 보였다. 따라서 항갑상선제 치료로 26개월 이상 관해가 되지 않을 경우에는 치료 방법의 변경을 고려하는 것이 관해율을 높이는데 도움이 될 것으로 생각된다. Background: Graves' disease in an organ specific autoimmune disease. Three kinds of therapeutic modalities (antithyroid drugs, ablation with radioactive iodine and subtotal thyroidectomy) are frequently performed for the management of this disease. The most popular therapeutic policy for the disease in Korea is antithyroid treatment. We analysed and compared the remission rates of all three modalities for Graves' disease, and evaluated the antithyroid modality to determine the correct duration of treatment. Subjects & Methods : The medical records of 205 patients with Graves' disease were reviewed. For the evaluation of the antithyroid modality medical treatment, antithyroid drugs were administered for more than 1 year. The prognostic factors associated with remission were analysed by means of an ROC curve. Results: 1) Of the 205 patients, proportions that received medical therapy, subtotal thyroidectomy and radioiodine therapy were 83.0, 14.1 and 2.9%, respectively. 2) The remission rates of the medical therapy, surgery and radioiodine therapy were 60.0, 96.5 and 83.0%, respectively. 3) The remission rate of the medical therapy was associated with the duration of medication and TBII activity. The determined proper duration for the antithyroid treatment was 26 months from the ROC curve analysis. Conclusion: The above results suggest that the proper duration of antithyroid treatment for Graves' disease is 26 months, after which time the subtotal thyroidectomy or radioiodine therapy should be considered if the disease has not remitted (J Kor Soc Endocrinol 18:24∼31, 2003).

김선형,박은희 숙명여자대학교 약학연구소 2003 약학논문집-숙명여자대학교 Vol.19 No.-

Ethanol extract of Phellinus linteus (PLE) were examined for anti-inflammatory effect in punch ear edema, anti-angiogenic effect using the chick chorioallantoic membrane (CAM) assay and analgesic effect on writhing test. The extract was found to contain the significant anti-inflammatory, anti-angiogenic and analgesic activity. Butanol fraction of PLE was the most active fraction. Thus, these results suggest that PLE and the fractions of PLE had anti-inflammatory, anti-angiogenic and analgesic activities.

엄형춘,장현섭,황선진 경희대학교 자연과학종합연구원 2003 자연과학논문집 Vol.9 No.2

하수슬러지의 탈수성 향상을 위한 제지슬러지 혼합탈수에 대한 평가를 실시하였으며, 탈수보조제의 혼합비율의 증가에 따른 CST, 침강성, 탁도, floc 크기 및 강도, 탈수케이크의 함수율 측정을 통하여 탈수성을 비교하였다. 제지슬러지 적정 혼합비율은 30% 정도인 것으로 밝혀졌으며, 제지슬러지의 주요 구성성분인 CaCO_(3), Talc, Pulp가 각각 하수슬러지의 탈수성을 개선시키는 효과를 보였다. 그리고 이들 세 가지 성분이 합된 합성제지슬러지에 의해 가장 낮은 함수율의 탈수케이크를 얻을 수 있었다. Improvement of sewage sludge dehydration efficiency by mixing paper sludge was investigated in this study. Capillary suction time (CST) and Settling test, Turbidity, floc size, floc strength, water content were utilized to assess sludge dewaterability. Optimum mixture ratio of paper sludge was proved 30% in mixing disposal. Dewaterability of sewage sludge significantly improved when sewage and paper sludge mixed.

ISDN is no longer either spiritual movement or just an interesting topic. Rather, it has become something realizable. The important factors which make the ISDN are digitization of communication network and the necessity to provide integrated services to the customer. In this paper, related to the ISDN switch structure, a new inter-processor communication network topology is proposed and it's performance is analyzed.

김선형 순천향대학교 1994 논문집 Vol.17 No.3

The objectives for this study is to develop the terminal monitor equipment of a monitoring system for the electric train car. This equipment collects the data of the operating status from the major machinery on electric train car. transfers the data to center monitor for displaying on the operating board, so that the operator can easily recognize the operating slate of the major machinery while the electric train is running. When an emergency occurs, it alerts the operator of any failures and gives him instructions by use of recording data from the machinery and transferring to center. As a resut of this study, we can expect that our deveolped system are very useful in the electric train car.
