건축공사의 고층화, 대형화에 따른 시스템 폼의 사용이 일반화 되고 있으며, 시스템 폼은 유로폼을 사용할 시 보다 수펼 레벨링, 건물의 외벽에 거푸집 설치 등의 시공성과 경제성 및 공기의 감소로 인한 경제적인 이점이 생기며, 이에 따라 대형 거푸집인 시스템 폼이 건축공사에 차지하는 비중이 늘어가고 있는 실정이다. 그러나, 시스템 폼에 관련한 사고사례들 또한 있으며 이에 본 연구에서는 시스템 폼 중 하나인 RCS FORM을 제조사인 A사와 B사 각각 2곳의 현장의 사례를 조사하여 취약점을 분석하고 개선방안을 도출하여 현업 전문가와의 인터뷰를 통해 취약점과 개선방안의 실적용에 대한 타당성과 보완점을 확보해서 최종적으로 실적용이 가능한 개선 방안 모델을 제시한다. The use of the system form has been becoming common due to the high-rise and large-scale construction of the buildings. The system form has economical advantages due to the workability and economical efficiency such as a horizontal leveling, As a result, the proportion of large formwork system forms in construction projects is increasing. However, there are also accident cases related to the system form. In this study, we investigated the cases from two companies, A and B, which are one of the system forms, RCS FORM. As a result of the investigation, we analyzed vulnerability, and draw up improvement plans. Through interviews with field experts, we propose a model of improvemet that can be implemented at the final stage by securing the feasibility and complementary points of the application of vulnerability and improvement plan.

N/A Objectives: To analyze 2942 cases of prenatal genetic amniocentesis with their cytogenetic results. Methods: This study reviewed 2942 genetic amniocentesis results which were perfomed at Ilsin Christian Hospital from 1993 to 1999, as prenatal genetic diagnosis for the possibility of chromosomal abnormality of fetus. Age distribution, gestational weeks, indications of amniocentesis and cytogenetic results were the key factors for the analysis. Results: Maternal ages were ranged from 20 to 45, mostly 25-39. Of indications of prenatal genetic amniocentesis, abnormal maternal serum marker was the most common(S7.9%) and followed by advanced maternal age(29.3/a). The frequency of abnormal karyotypes was 3.1%(90/2942). Down syndrome(trisomy 21) and inversion of chromosome were found at 0.8%(24/2942) and 1.0%(30/2942). The incidence of abnormal karyotype according to indication had statistieal significance in family history and abnormal ultrasonographic findings. (p < 0.001) Conclusions: Midtrimester genetic amniocentesis is an important diagnostic tool in prenatal genetic diagnosis. In addition to the maternal serum markers and maternal ages, complete family history takings and ultrasonograms should be considered in prenatal genetic counseling.
