The purpose of this study is to develop models and instruments for teaching and assessing scientific experiments and practices. General objectives for teaching and evaluating scientific experiments and practices in secondary schools were analyzed and categorized into three domains:they were inquiry skill, scientific thinking skill, and scientific attitude. The sub-categories for each domain were constructed, and specific objectives for each general objective were also stated in terms of behavioral objectives according to Mager's suggestion. The tables of specification (content×behavior) were developed in order to assist secondary school teachers to teach and evaluate scientific experiments in class. In addition, we introduced some useful assessment techniques which can be adopted to evaluating learning outcomes of each specific objective. The sample test items corresponding to each objective were listed for practical usage in class.

Recently, As large scale construction works are widely prevalent a more scientific approach to construction management is required. also, each construction company is searching for a new computer information management system as part of computerization of construction management. Especially in the field of process control management, which constitutes the core of construction management business, a software system that is already available in the market is used, while new software systems are being developed. but, the effective ness of process control softwares as they are used today is yet to be verified. Therefore, the purposes of this study are to identify the problems of process control through investigating the operational realities of process control software in the construction field.

To address the ability of Kung-Kyung-Ilho-Jeon(KK) to induce cell death, we investigated the effect of KK on cell viability. Forty-eight hours later, loss of viability occurred following KK exposure in a dose-dependent manner. The treatment of KK, a commonly used herb formulation in Korea and China, caused a decrease in cell viability. KK also resulted in apoptotic morphology a brightly blue-fluorescent condensed nuclei by Hoechst 33258-staining, and reduction of cell volume. Our results show that KK induces caspase-3 and -9 activation in a time-dependent manner. In addtion, the translocation of cytochrome c release into cytoplasm has been observed under the presence of $5mg/m{\ell}$ KK. The subsequent loss of mitochondria membrane potential is collapsed by the addition of KK. Our immunoblotting data show that PARP, a well known caspase-3 and -6 substrate, is cleaved by KK. We show that a pro-apoptotic protein, Bax is increased in the presence of KK but that the amount of Bcl-2 is not changed. We suggest that Bax, a critical protein which can regulate channel of mitochondria to release cytochrome c, is a key protein in KK-induced apoptosis of Hela human cervical carcinoma cells

심장 점액종 환자에 있어서 점액중의 색전에 의해 복부 대동맥이 폐쇄되는 경우는 아주 드문 합병증으로 지금까지 보고된 바가 드물다. 현재까지 심장 점액중의 병태 생리 및 자연경과에 대해서는 잘 알려져 있옴에도 불구하고 점액중의 분리 에 의한 혈관 색전증은 예상치 못한 심각한 합병증을 초래 할 수 있다. 본 증례는 심장 점액종 색전에 의해 복부 대동맥폐쇄가 발생한 환자에서 수술적 색전 제거술 및 점액중 절제술로 치료한 경험을 보고 하고자 한다.

목적 : 조산아의 주산기 예후를 결정하는 위험요인을 분석하고, 각 요인별 예후를 비교분석함으로써 조산아 관리의 산과적 지표를 산출하고자 하였다. 연구 방법 : 2000년 1월 1일부터 2002년 12월 31일까지 조선대학교병원에서 분만후 신생아 집중치료실(NICU)에 입원한 37주 미만의 조산아와 신생아 집중치료실 (NICU)에 전원되어 입원치료한 조산아 236예를 대상으로 하였다. 조산아의 생존률, 이환율, 합병증, 장ㆍ단기 예후 등을 후향적으로 조사하였다. 결과 : 출생시 체중 및 재태연령은 주산기 예후를 결정하는 주요한 산과적 요인이다. 조산의 주산기 합병증을 보면 빌리루빈혈증이 27.5%로 가장 많았고, 호흡 곤란 증후군이 24.2%, 패혈증이 11.4% 등의 순이었다. 조산의 원인에 따른 생존률은 임신성고혈압 (88.2%)이 가장 높은 반면 자궁경부무력증 (50.0%)이 가장 낮은 생존률을 보임으로서 원인질환에 따른 생존률의 차이가 있으며, 자궁경무부력증의 경우 진단이 도면 대게 조산으로 귀결되므로 조산예방을 위한 조기진단과 치료가 필요하다. 결론 : 조산아의 생존률을 증가시키기 위해서 조기진통은 최소 제대연령 27주, 출생체중 1000 gm까지는 조절되어야 한다. Objective : To investigate the change of prognosis of the preterm infants delivered in Chosun University Hospital. Methods : A study was conducted for 236 newborns who were born at Chosun University hospital from January 1. 2000 to December 31, 2002. The data were collected by review of the hospital record. Results : 1) The survival rate of the preterm infants who weigh below 999 gm was 2% and 68.4% in 1,000-1,499 gm of infants 90.9% in 1,500-1,999 gm of infants and 92.7% in 2,000-2,499 gm of infants respectively. 2) The survival rate of the preterm infants who born 25% at 25-26 weeks, 50% at 27-28 weeks, 80% at 29-30 weeks, 88.2% at 31-32 weeks, 94.4% at 33-34 weeks and 95% after 35 wks respectively. 3) The cause of preterm delivery were premature rupture of membranes (41.7%), preterm labor (23.7%), pregnancy induced hypertension (10.9%), multiple pregnancy (8.3%) etc. 4) The perinatal complications of the preterm infants were hyperbilirubinemia (27.5%), respiratory distress syndrome (24.2%), sepsis (11.4%) etc. Conclusion : To increase the survival rates of preterm infants, the preterm labor should be controlled by 27 week`s gestation and the birth weight of 1,000 gm minimally.
