목적 : 산과적 수술 영역에서 Safil(R)/Safil(R) Quick/Monosyn(R) 합성봉사들의 유용성을 평가하고자 하였다. 방법 : 2004년 4월부터 9월까지 삼성서울병원 산부인과에서 질식 자연분만을 한 100명의 산모와 제왕절개 수술을 시행받은 198명의 임산부를 대상으로 하였다. 질식 분만 시 회음절개의 봉합 치료군 50명에게는 Safil(R) Quick, 대조군 50명에게는 chromic catgut을 사용하였고, 제왕절개 시 대상 환자를 두 군으로 나누어 첫 번째 군에는 100명을 포함시키고 두 번째 군에는 98명을 포함시켰다. 첫 번째 군인 자궁 절개 봉합 치료군 50명에게는 Monosyn(R), 대조군 50명에게는 chromic catgut을 사용하였고, 두 번째 군인 근막 봉합 치료군 49명에게는 Safi(R)을 사용하였고, 대조군 50명에게는 Vicryl(R)을 사용하였다. 이들을 대상으로 수술 전후, 퇴원 시, 퇴원후 상처 봉합 상태 및 합병증들을 조사하였다. 결과 : Chromic catgut을 사용한 군과 비교하였을 때, Safil(R) Quick 군은 질식 분만일로부터 퇴원일까지의 기간이나 분만 후 봉합 부위 치유 상태 및 감염, 혈종, 열개 등의 합병증의 빈도가 차이가 없었고, Monosyn(R) 군도 제왕절개 수술 시간이나 수술 3일 후 헤모글로빈 수치의 감소 및 합병증의 빈도가 차이가 없었다. Safil(R) 군도 Vicryl(R) 군과 비교하였을 때 제왕절개 수술 시간과 퇴원시의 통증 강도 및 합병증의 빈도가 유의한 차이를 나타내지 않았다. 결론 : Safil(R) Quick은 회음절개의 봉합에 있어 chromic catgut의 대체 봉합사로 사용될 수 있고, Monosyn(R)과 Safil(R)은 각각 제왕절개 시 자궁 절개 부위와 근막의 봉합에 chromic catgut과 Vicryl(R)의 대체 봉합사로 사용될 수 있다. Objective : To evaluate the clinical applicability and safety of absorbable synthetic suture materials (Safil(R)/Safil(R) Quick/Monosyn(R)) in obstetrical surgeries. Methods : This clinical trial includes 100 patients who delivered vaginally and 198 patients who were undergone cesarean section from April 2004 to September 2004. In cases of vaginal delivery, patients were divided with the same number into the study group in which Safil(R) Quick was used and the control group in which chromic catgut was used for episiotomy and perineal laceration repair. In case of cesarean delivery, patients were divided into two groups. The first group which included 100 patients was subdivided with the same number into the study group in which Monosyn(R) Was used and the control group in which chromic catgut was used for uterine repair. The second group which included 98 patients was subdivided with the same number into the study group in which Safil(R) was used and the control group in which Vicryl was used for rectus fascia repair. Wound healing status and complications are assessed during postoperative stage, at hospital discharge, and at postpartum out-patients follow-up. Results : Compared with chromic catgut groups Safil(R) Quick group showed no difference in hospital stay from vaginal delivery, wound healing status and surgical complications and Monosyn(R) group showed no difference in operating time, decrease in hemoglobin at postoperative day 3 and surgical complications. Safil(R) group showed no difference in operating time, postoperative pain and surgical complications compared with Vicryl group. Conclusion : Safil(R)/Safil(R) Quick/Monosyn(R) were equivalent with regard to most aspects of their clinical suitability and may be useful alternative suture materials in obstetrical surgeries.

Pipe support is a representative structure that supports slab formwork, and it is a representative temporary equipment that has been systematically managed since the 1990s when the domestic temporary equipment performance test system was introduced. Nevertheless, it is also a reality that many of the products in circulation are used products that are reused and do not meet the performance of the initial manufacturing stage. However, if only new products are insisted, it could lead to delays in the process due to an increase in construction costs and difficulties in timely delivery. On the contrary, it is not acceptable for the safety of the construction site to use products of low quality without verification procedures or standards. Therefore, this study attempts to grasp the management system such as safety certification for temporary equipment and the actual condition of quality control to maintain performance, and propose improvement plans.

The Temporary construction refers to the construction or dismantling of temporary structures installed for the construction of the main structure at the construction site, and the members constituting this temporary facility are called temporary equipment. Temporary equipment used in construction sites is mostly used products that are reused rather than new products, and it is necessary to consider performance degradation due to repeated use. This study is a preliminary study to develop the performance evaluation criteria applied to temporary equipment that is distributed and reused for secondhand. This study is to analyze the performance status of temporary equipment of used goods owned by rental companies by condition grade through performance tests.

재사용 파이프서포트의 성능기준 연구

건설현장에서 사용 중인 가설기자재는 신제품보다 대부분 재사용품이 사용되고 있기 때문에 여타 건설자재나 부재처럼 신제품에 대해서 만 품질관리기준을 수립하기에는 현실적 적용단계에서 많은 문제가 발생할 수 있다. 특히 반복 재사용으로 인한 성능저하가 발생할 수 있는데, 이에 가설기자재별 적정한 성능기준의 마련을 통해 일정한 품질을 확보할 필요가 있다. 따라서 본 연구에서는 가설기자재별 성능기준을 마련하기 위한 목적으로 문헌 조사 및 성능시험을 실시하였으며, 그 일환으로 파이프서포트의 성능기준에 대한 연구를 통해 적정한 재사용품의 성능기준을 제시하고자 하였다.

System scaffolding and shoring are temporary structures in which vertical members, horizontal members, bracing members and trusses are assembled and installed. In order to ensure quality and safety, the quality test shall be carried out in accordance with the Guidelines for Quality Management of Construction Works (MOLIT Notice No. 2020-750). The quality test method (national standard) for Components for tied post system scaffolding and shoring is based on the Korean standards (KS F 8021) and the Safety certification standards (MOEL Notice No. 2021-22). However, the two standards differ in some aspects such as performance standards and etc, so cause confusion when applying them on-site. In addition, the standard for truss are applied only to trusses for shoring and cannot be applied to trusses for scaffolding. Therefore, this study aims to unify the two national standards and establish realistic standards.

Based on the survey analysis of safety accidents at construction sites that occur every year, most of them are caused by temporary structures. While analyzing in detail, it is confirmed that the main factors for such accidents are the quality problem of temporary equipment, unstable construction, and arbitrary change. As temporary structure is installed only for the construction of main structure, the reality is that no attention is paid to the construction of temporary structures.

목적: 융모막성에 따라 체외수정에 의한 쌍태 임신의 예후를 자연 쌍태 임신의 예후와 비교하고자 하였다. 연구 방법: 1994년 10월부터 2003년 12월까지 쌍태 임신으로 분만한 598명의 임산부를 대상으로 후향적 고찰을 하였다. 392예는 자연임신군이었고, 206예는 체외수정에 의한 임신군이었다. 대상 환자들의 산과적 합병증을 포함한 임신 및 주산기 예후를 비교 분석하였다. 또한 융모막성에 따라 일융모막과 이융모막으로 대상군을 세분하여 임신 및 주산기 예후를 다시 분석하였다. 결과: 체외수정군에서 37주 미만의 조산 빈도가 많았다(74.5% vs. 82.5%, p=0.031). 그러나 평균 재태 연령은 유의한 차이를 보이지 않았다(34.5±2.86주 vs. 34.2±0.28주). 산전 입원 빈도 역시 체외수정군에서 많았다(4.6% vs. 9.2%, p<0.001). 다른 주산기 예후는 두 군간에 차이를 보이지 않았다. 융모막성에 따라 임신 예후를 다시 분석한 결과에서는 이융모막의 경우 체외수정군에서 신생아중환자실 입원 빈도 (42.7% vs. 52.6%, p<0.05)와 괴사성장염이 자연임신군에 비해 많았고 (0.5% vs. 3.5%, p<0.05), 일융모막의 경우 체외수정군에서 전치태반의 빈도가 많았다(0% vs. 11.8%, p<0.001). 결론: 결론적으로 체외수정에 의한 쌍태임신이 자연 쌍태임신에 비해 일융모막성의 경우 전치 태반의 반도가 증가하고, 이융모막성의 경우에는 신생아 중환자실 입원 빈도와 괴사성 장염의 빈도가 증가된다. Objective: To compare the pregnancy outcomes of in vitro fertilization (IVF) twins with those of spontaneous twins based on their chorionicities. Methods: We performed a retrospective analysis of 598 twin pregnancies beyond 24 weeks of gestation delivered from October 1994 to December 2003. Subjects were grouped into the spontaneous group (n=392) and the IVF group (n=206) and then subgrouped into dichorionic (n=193, spontaneous vs. n=156, IVF) and monochorionic (n=154, spontaneous vs. n=34, IVF) subgroups. First, the obstetric and perinatal outcomes were compared between the spontaneous group and the IVF group regardless of their chorionicity. Second, the same outcome variables were compared between the spontaneous and the IVF group with same chorionicity. Results: There was a significant increase in the incidence of preterm deliveries before 37 weeks of gestation in IVF twins (74.5% spontaneous vs. 82.5% IVF, p=0.031). However, the gestational age at delivery was not significantly different (34.5±2.86 weeks vs. 34.2±0.28 weeks). Antepartum admission was also significantly increased in IVF group (4.6% vs. 9.2%, p<0.001). We were unable to observe any significant difference in perinatal outcomes between the two groups other than increased in utero fetal demise in utero in the IVF group (0.3% vs. 1.5%, p<0.05). When we reanalyzed pregnancy outcomes based on chorionicity, there were more frequent admission to neonatal intensive care unit (42.7% vs. 52.6%, p<0.05) and necrotizing enterocolitis (0.5% vs. 3.5%, p<0.05) in dichorionic twins of the IVF group. In monochorionic twins, the incidence of placenta previa was increased in the IVF twin group (0% vs. 11.8%, p<0.001). Conclusion: In the IVF twins, the incidence of placenta previa was increased in monochrionic twins and the incidence of neonatal intensive care unit admission and necrotizing enterocolitis were also increased in dichorionic twins.
