There are something unreasonable, unsatisfactory on the law system for laboratorial safety enforced by the government from April 2006. Therefore, the system should be reviewed and revised to be satisfactory for current research condition. This study is to analyze research areas for improving laboratorial safety and to show safer ideas. With more detail, more practically improving ideas have been shown for systemizing safety assessment in advance, effective organization of laboratory, safety committee and their regulation. It is expected that better safety level all the concerned engagement, reasonable revision of safety regulation of laboratory, can be made by this research result.

The Ministry of Employment and Labor implemented the process safety management(PSM) system from 1996 to prevent major industrial accidents caused by chemical substances, but the number of accidents did not drastically decrease. Even in workplaces with excellent PSM ratings, large-scale chemical accidents still occur due to non-compliance with safety work procedures and insufficient safety measures during maintenance and other work. Accordingly, the chemical accident risk warning system was introduced in 2014 to supplement the PSM system and prevent accidents that may occur during regular or unexpected maintenance and repair work. In the meantime, changes in the safety management system have been checked since the introduction of the chemical accident risk warning system at chemical handling workplaces, and based on the results, a plan for upgrading this system has been proposed. The effect of the CARW system was found to directly prevent accidents through wired and on-site consulting and post-management at the workplace and indirectly contribute to the establishment of a safety and health management system at the workplace, such as improving safety culture awareness.

A Structure of a system is usually described as same as an architecture, but they are basically different. The architecture has a broader meaning than a system structure. In other words, an architecture can include many of system structures. So, to define the architecture, we need to consider how functions of a system are consisted and integrated. The architecture defined is applicable to railway safety management systems, and it can be made as a new model for railway safety systems, which is useful to systematize railway safety regulations. To establish the architecture as applicable to railway safety regulations, it is required to compare between regulation relations by analyzing roles before/after executing railway safety regulations. Therefore, in this research, we reviewed and classified different types of regulation conditions and safety requirements for railway systems and a variety of conditions before/after railway safety regulations changes are compared by defining system architectures subject to National railway safety.

In this study, safety requirement & criteria for high-speed rail system were developed for safety verification as a national rules and regulations. Safety criteria were presented through analysis of high-speed rail development specification, survey of related regulations for safety requirements. and review of operation compatibility with domestic rail system. Finally, safety rule consist of system safety requirements and safety criteria for technical parts.

In the early 1960s, US Air Force lost missile launch bases during ICBM development by a defect in the missile design and operation plan. U.S. DoD realized the limitation of the existing accident prevention method. Therefore, the weapon development required system safety activity, and procurement projects of U.S. DoD applied MIL-STD-882(System Safety). Development projects of U.S. DoD more emphasized the importance of system safety after the space shuttle Challenger exploded in 1986. Currently, Airworthiness certification for military aircraft uses system safety to minimize accidents. The domestic defense aviation R&D projects also use the system safety for the airworthiness certification. However, non-aviation weapon R&D projects rarely applied system safety. This paper presents a system safety application method for domestic weapon R&D projects by studying the U.S. military standards/organizations and domestic defense aviation projects.

The purpose of this research is to understand the role of safety climate in the safety management system. Based on the 121 responses from facilities got Occupational Health & Safety Assessment Series (OHSAS) 18000 certification, the results of statistic analysis show that there is significant relationship between safety climate, work attitudes and Organizational Citizenship Behaviors (OCB). The most important finding is the relationship between safety climate and organizational commitment will mediate the relationship.

In this paper we present a safety plan to be applied to the development of the TCS(Train Control System). The safety plan that can be applied to the life cycle of a system, from the conceptual design to the dismantlement, shows the whole process of the paper work in detail through the establishment of a goal, analysis and assessment, the verification. In this paper we study about the making a plan, the preliminary hazard analysis, the hazard identification and analysis to guarantee the safety of the TCS. The process far the verification of the system safety is divided into several steps based on the target system and the approaching method. The guarantee of the system safety and the improvement of the system reliability is fellowed by the recommendation of the international standards.

This paper propose the safety design of automatic train control system which is used for controlling and monitoring train speed not to excess a permitted speed. Safety activities are shown for the computerized system to achieve a required safety requirement. The safety activities are composed of system dynamic modelling to identify potential hazards contained in the target system, to analyze sub system faults to provoke the hazards. Risks analysis are carried out to estimate losses caused from the hazards to allocate safety requirement. We Proposed design solutions for sub system to meet safety requirement.

In this article, we verify to influence in the management performance by the safety management system that is recommended by the ICAO for the safety management on the airside area in the airport. Also, We present a comprehensive mediator effect that the employees perceive safety culture and safety behavior. We design how participants were selected as study the employees from 4 airports on the airside areas of the Incheon International Airport, Gimpo International Airport, Jeju International Airport and Gimhae International Airport in the Korea using the simple random sampling method. The instrument for data collection was a questionnaire, and it was developed. Data analysis was to conduct structural equation modeling. Test of the hypotheses were verified to Maximum Likelihood Estimator. As a result of the analysis, safety behavior and risk management of the safety management system found out that affect management performance. Also, the employees of a high awareness about safety policy could be seen that is a high impact on management performance through a safety culture and a safety behavior. Safety behavior has significant mediator effect within the relationship between the safety management system and management performance. So, We provide guidance of the safety policies for the safety management on the airside area in the airport.
