Risk management is an important part of system assurance and it is widely used in safety-related system. Railway signal system is one kind of safety-related system and its most important goal is to guarantee the safety of railway system. The method based on risk management can find and solve the security issues of railway signal system more effectively. This paper introduces the basic conception of risk management, studies the whole process of risk management and related tools and techniques and discusses some key points qualitatively combining with the particularity of railway signal system.

In this paper, we conduct a study on the design that can secure the safety of the EPLA system by performing safety activities based on the ISO 26262 standard for vehicle functional safety. In the case of a company developing a detailed system, it is responsible for verification through hardware design and safety analysis in the overall flow of safety activities, and safety analysis according to the ASIL safety level must be properly performed. At this time, there are cases where the safety goal quantitative metric value suggested by the ISO 26262 standard cannot be satisfied only by the hardware design of the basic function, so it is necessary to design and install the safety mechanism. Based on ISO 26262 safety activities, it is possible to derive an effective design plan through hardware safety analysis.

This study organizes not only the middle-long term developing plan of safety health education to put emphasis on a manufacturing industry, but also the developing plan of activating the domestic safety health education. On the basis of this study, current safety health education can be developed. To achieve a goal of implementing domestic safety health education, this study is carried out more deeply as follows.

The objective of this study is to improve safe execution of the management plan in Construction Technology Promotion Act. This research addresses the issue how to prevent the collapse of facilities under construction and after completion, improve the examination system, and execute Improvement of Safety Management Plan. To achieve this goal, research providing insights into understanding the ways in which creating and presenting safety checks and deploying safety training measures effectively is imperative.

The country has been to industrialization, urbanization, centralization due to rapid economic growth and industrial facilities are aging by focusing on economic growth. These industrial facilities are often due to an unexpected accident occurred. This study was performed for suggesting the plan to promote the function of safety management for national infrastructures. In order to achieve the goal of study, safety association laws were analyzed, and safety-related organizations were investigated by business fields.

In order to reduce the risk of accidents, we proposed a construction safety management system combined with wearable device and LoRa (Low-Range Wireless Network) communication method to apply the usefulness of Internet (IoT) technology which means "everything connected". to construction safety management Management system. The proposed wearable safety device is a device that relays information exchange between wearable safety device and safety management server by LoRa wireless communication method. The safety management server can store workers bio-data and perform big data analysis. If a risk factor is determined from the analysis result, a warning is sent to the wearable safety device and the manager's application. The goal of this system is to prevent construction workers from entering the dangerous area that is not suitable for work, and to prevent safety accidents caused by human cause by detecting abnormal condition during work.

System safety management to secure complicated system safety such as railway and nuclear includes various factors. Those are prevention of accidents, faults management, human factor, men-machine relation, organization factor, safety culture, quality/quantity safety performance goal, and safety regulations. To manage them, it is required that database which is based on most analysis is established. Therefore system safety could be controlled. This research defines data required to safety management, and that is aimed at deriving plans in order to establish them as database. To accomplish that, safety information management of other systems such as aviation and marine is reviewed. Also, the present conditions of available data in the filed of domestic railway are analysed, and then it provides plans for. establishing database to build up advanced railway system safety information management systems.

This research presents how to make more efficient management for preventing accidents in construction site. One of the most efficient way to do so is to quantify those potential hazards and risks, resulting from it. Also it has been tried to rate & weigh each Item of those hazards, depending on the degree of risk. The goal if this qualification method is to establish ensuring the required safety. These are rated & compared with the degree of understandings of each item & accomplishment of those codes.

The tower cranes are the very useful construction machine in the high place works. But they are very susceptible to the load balance, the wind load and the hanging load because they are the very slender structures and those center of gravity is located in the upper part. Therefore, the collapse accidents of tower one have repeatedly happened during the assemble or disassemble works. The correcting frame may has often used in order to correct the error in the setting of foundation anchors. The goal of this study is that propose the methods preventible the collapse accident of tower crane which is constructed by using the correcting frame. In order to accomplish the goal of this study, the field survey, the reference investigation and the structure analysis were performed for the collapse accident of tower crane using the correcting frame. This study result in the methods preventible the same accident.
