회복성 개념을 적용한 승강장 스크린도어 안전관리 방안 연구
권순범,이용재 대한교통학회 2016 대한교통학회 학술대회지 Vol.75 No.-
도시철도 승강장 스크린도어는 승강장과 선로사이에 설치된 고정벽과 가동벽을 통해 승객의 안전을 도모하기 위해 설치된 시설물로서 열차와 연동하여 자동 개폐되는 장치이다. 이러한 자동화 장치의 경우 내부 구성요소가 복잡하게 연계하여 작동하는 특성을 지니고 있으며, 이러한 복잡성은 내부 요소의 단순 결함이 예기치 않은 대형 참사로 이어지게 되는 동기를 제공하기도 한다. 최근들어 도시철도 승강장 스크린도어의 경우 유사한 사고가 반복적으로 발생되고 있어 지금까지의 비상시 장애 또는 사고에 대처하는 안전관리 방법론으로는 한계가 따르는 것으로 판단된다. 이에 대한 대안으로 시스템의 기능유지에 중점을 두는 회복성 공학(Resilience Engineering) 개념의 도입은 전략적 사고예방을 통한 상시 위험관리체계의 구축과 피해발생에도 신속히 기능을 회복(Resilience)하는 시스템적 능력을 향상시킬 수 있는 새로운 안전관리 체계를 제공할 것으로 판단된다.

Objectives : The aim of this study is to investigate the effect of acupuncture stimulation on the relationship of change in magnetocardiography (MCG). Methods : For this purpose, 30 heart deficiency volunteers were acupunctured at Shinmun (HA7) and Naegwan (PC6) acupoint. Then, we measured and observed the change of frequency parameters in MCG. Results : In the mean frequency, during and after acupuncture treated groups of PC6 were decreased the activity of compared to the control group. In the median frequency, during the acupuncture treated group of PC6 was decreased the activity of compared to the control group. Conclusion : These results suggested that acupuncture stimulation plays an important role to the activities of MCG

Waste generated during the dismantling of nuclear power plants is not only diverse in typessuch as metal, concrete, soil, but also in a large amount, requiring systematic and efficient management. It is very important to quickly and accurately measure radioactive contamination of wastes generatedsimultaneously at the decommissioning site, classify them by level, and make decisions so that theycan be disposed of in accordance with related laws and regulations. In this paper, for the technical andeconomic aspects of recycling of radioactive metal waste generated during the dismantling of nuclearpower plants, we propose a management system that can measure the radioactive contamination byshape of metal waste at the decommissioning site and automatically classify it according to the presenceor absence of contamination. Accordingly, a system for collecting information on metal samples such asweight measurement and shape acquisition of metal waste, measurement of radioactive contaminationand identification of nuclides, and an automatic classification system according to radioactivitymeasurement results were described.
