Various elements such as geometry, traffic safety facilities, congestion level, weather, etc., need to be appropriately reflected in the assessment scenario evaluating the driving safety of automated vehicles. Therefore, this study first established a scenario structure and defined the layer of elements, to derive the elements to be reflected in the automated driving safety evaluation. After that, all elemental candidates that can be reflected in each layer were derived by reviewing the relevant literature. Finally, as a result of an expert survey, 77 items were selected to be reflected in the automated driving safety evaluation. The selected elements are expected to be actively utilized in developing scenarios for the driving safety evaluation of automated vehicles in simulation, proving ground, and real road assessments.

Safety management has been one of the most critical issues in the construction industry for a long time. Despite continuous efforts, it still shows a higher accident rate than other sectors. To reduce the accident rate, a lot of studies have been performed, mostly focused on contractors or construction phase. Although the initial stage of the construction project has the most significant impact on construction safety and decision-makers at the initial stage play an important role, the safety management system throughout the project entire life-cycle is still insufficient. In addition, although a great deal of information is generated in the construction project and the value is increasing, while it shows an inefficient aspect. This is believed to be due to insufficient information exchange and a lack of standards. In this context, this study aims to analyze the efficiency of information handover in construction safety. For this purpose, a safety management framework for systematically and efficiently managing and utilizing for construction safety information is referred to as 'safety business functions', 'project life-cycle', and 'industrial hierarchy'. The 'safety business functions' are classified into three levels. And then, in order to analyze the efficiency of safety information handover, 'importance of safety business function' and 'efficiency of safety information handover' were evaluated by interviewing with experts. This study can be used as reference data for implementing systematical and efficient safety management, and can also increase construction safety competency.

Recently chemical intoxication related with the use of chemical extinguishing agents occurs frequently. With the industrialization, high-rising of building and increase of fire risk, we use the various extinguishing agents and the safe use become important. In this study I carried out the risk assessment of representative chemical extinguishing agents (HCFC-123, HFC-125) using the CHARM and got the meaningful qualitative outcome. This study is significant in that the risk assessment of chemicals was conducted using CHARM, chemical risk assessment tool. It is expected that the results will be utilized as the basic data for the national chemical safety management.

As the consumption of LNG has increased, the capacity and number of LNG facilities are getting bigger and bigger. Such circumstances supports the need for a dedicated risk analysis model to help review and check major issues of the safer construction and operation of LNG storage facilities systematically. Therefore this study suggests an appropriate risk analysis model that enables us to evaluate hazards of LNG storage facilities more easily and systematically, and then to use its result in siting, design and construction stages of the facilities. ill order to develop the model, lots of existing studies and domestic and foreign codes and standards were fully reviewed and a series of case studies also were carried out. The suggested model consists of 4-stage evaluations: in selecting a site, in determining a layout, in designing and constructing the facilities, and in operating them. This model also suggests the weather condition necessary for estimating the consequence of accident-scenarios, and the easy, systematic approach to the analysis of their probability. We expect that the model may help secure LNG storage facilities' inherent safety in determining their site and layout.

Safe plants are maintained by the systematic identification of potential hazards. Various hazard evaluation methods have been developed in pursuit of safe plants. Recently, much efforts has been made for the automation of hazard evaluation system by introducing expert system to get rid of weak points of the conventional hazard evaluation methods. HAZOP study is recognized as one of the most systematic and logical hazard evaluation methods. However, it has several disadvantages; experts should participate simultaneously, the detailed study is time-consuming, and the quality of the results largely depends on the quality of the experts. Therefore, the automation of HAZOP Study is highly beneficial for reducing the required time and obtaining the consistent evaluation results. In this study, a framework for the automation of HAZOP study is suggested. Based on the suggested framework, HAxSYM, an expert system to automate HAZOP study, has been developed. The case study validates the performance of the developed system, and the results are compared with the results from the conventional HAZOP study.

지구 온난화의 원인이 되는 이산화탄소를 저감하며 유해한 배기가스를 배출하지 않는 수소연료전지자동차(FCV)에 대한 관심이 높아지고 있다. 한국가스안전공사에서 현재 구축하고 있는 평가장비는 이러한 수소연료전지자동차용으로 사용되는 고압용기의 수압반복시험 및 밸브류로 구성된 고압수소저장시스템의 단품 및 시스템 평가를 통한 안전신뢰성 검증을 목적으로 하고 있다. 현재 수소연료전지자동차는 차량이나 부품의 시험 방법에 대한 통일된 기준/표준/시험법이 아직 완전하게 정비되어 있지 않고, 시장에서의 도입 제도, 기준 등이 만들어지고 있는 현실이다. 또한 연료로 수소를 사용하는 도입단계에 있기 때문에, 수소용기가 반복압력변동에 따라 어떤 거동을 나타내는지에 대한 실험관련 연구가 미진한 상태이다. 따라서 수소연료전지자동차용 고압수소저장시스템에 대한 내구성, 안전성 확보를 위하여 수소연료전지자동차에서 중요한 부품인 용기에 대한 반복피로시험이 필요하다. 특히 복합재 용기 분야에서 Type3용기에 대한 높은 안전성과 내구성이 보고되고 있지만 실질적으로 얼마나 다른 용기에 비해 높은 성능을 가지고 있는지 국내에서는 체계적으로 검증된바 없다. 따라서 구축된 수압반복 장비를 이용하여 Type3 용기에 대한 수압반복시험을 실시하였으며, 이를 통해 수소용기의 거동을 확인하고자 한다.

Although many different intrusion detectionsystems have been developed there have not been enough researches on the methodology for evaluating these intrusion delection systems. With this understanding,in this paper we present a methodology for evaluating infrusion detection systems from the view point of performance and robustness, both of which are considered the most important criteria Current research on evaluating the performance f intrusion detection systems mostly foduson the in issuse detection but not on the anormaly detection. Regarding evalieting robustness it is not easy to apply off -line methodologies and methods for testing robustness hae not been proposed in on -line methodolomes, In this paper we provide an systematic way of classifyin and generating anomalies and using this reult, present an methodology for evaluating the pertormance of intrusion detection systems in detecting anomaalies ans well as misuses . Moreover, ww study the factors that can damage the robustness of intrusion detection systems and suggest an methodology for assessing the robustness of intrusion detection systems.
