Railway system which has latent loss of lives and property by big accident with that human error such as locomotive driver, manager, signaller, and the others involved. So human error management is needed to control this complex system and to confirm safety of it. Rail human error research for managing human resource has grown rapidly in both quantity and quality of output over the past few years. The continual influences of safety concerns, new technical system opportunities, reorganization of the business, needs to increase effective, reliable and safe use of capacity, and increased society, media and government interest have now accelerated rail human factors research programmes in several countries. The objective of this research is to improve safety and to reduce accidents in korean railway system, through the application of research results to the investigation of requirement for human error.

The energetic and environmental problems have been getting serious after the revolution of modern industry. Therefore, demand of gas as an eco-friendly energy source is increasing. With the demand of gas, the use of gas is also increased, so injury and loss of life by the fire have been increasing every year. Hence the influence on flame caused by Vapor Cloud Explosion in enclosure of experimental booth was calculated by using the API regulations. And the accident damage was estimated by applying the influence on the adjacent structures and people into the PROBIT model. According to the probit analysis, the spot which is 5meter away from the flame has nearly 100% of the damage probability by the first-degree burn, 27.8% of the damage probability by the second-degree burn and 14.5% of the death probability by the fire.

The purpose of this study is to investigate the safety consciousness of the lobours working at the ship building or repairing yard at which the industrial accidents frequently happen, and to provide the basic data required for the prevention of those accidents. This study is made by analyzing the questionnaires of 208 labours working at various ship building or repairing industries at random. This questionnaire is focused on finding the basic data for prevention of industrial accidents and getting the public opinions and proposals of labours. The results obtained by this study are as follows ; The negative estimations of the labours to the safety are cultivation of safety consciousness, the safety behavior in company, the molters of arrangement and the estimation of industrial or post arrangement. The positive ones are the arrangements of the protective tools and equipments for safety, the rule of safety regulation and the order of works, and the status of health education within company.

Construction companies economic to lighten the restrictions on safety education and training due to the domestic recession as long as the global downturn. With this, the Korean government lightened that restrictions, but the incidents are being sharply increased nowadays. The construction industry is more hazardous than any others, so, they insist to reinforce the training for incidents prevention, but it is prone to be disregarded at the subcontractors of the bigger construction companies due to their financial problems. According to these matters, this study hereby surveyed regarding their suggestions for the improvements of the training concepts through questionnaires below.

The electric shock victims were predominantly male, and more than half of the victims were found in companies with less than five employees in terms of the scale of company, and also more than half of victims had less than one month of experience for work experience. Considering the category of industry, more than half of the victims were engaged in construction, and considering the subcategory of industries, more than 60% of electric shock victims were found in building and other construction works. This study intended to conduct an in-depth analysis on the cause of electric shock accidents to provide basic data for policy proposing taking into considering the characteristics such as the electric shock path, low voltage, grounding and protection of workers. Also this study conducted an in-depth analysis of electric shock accidents for the past eleven years taking into account the necessity of a long-term plan.

The safety of the present railway system has been established through a lot of experience from the railway accident. But nowaday scientific safety assessment methods are exactly required to improve the safety of railway system. In this study, we focused on the methodology of probabilistic risk assessment, which has been developed mainly in the field of nuclear power industry, and considered the process to adopt this method to railway system in order to establish a scientific and comprehensive way of safety assessment.

In the domestic nuclear power industry, concern about safety of nuclear power plants is continuously increased with the Fukushima nuclear power plant accident. In order to enhance the safety of nuclear power plants, it is important to ensure that the power plants are operating with proper margin within the original design bases. Margin management is the process of ensuring that the NPP designer and operator are aware of the physical and operating limits, and potential and probability of failure, for each component in the plant. All components are subject to margin considerations, but the most important components by scope and attention are those related to safety-related systems and NPP safe shutdown.

The law(construction standard specification, construction, standard-work regulation, Industry safety standard related regulation) related to the installation of scaffolding being used commonly on the construction site is regulated that the gap of ledger is within 1.5m and first ledger is within 2m. The gap of ledger here is essential for the stability of scaffolding structure. But it is determined that it is possible for the gap of ledger is applied by explaining safety handrail as ledger, because of the fact that in current, on the construction site, safety handrail is installed with the material of scaffolding ledger as a steel tube pipe. On this study, it is aimed to guarantee the safety by analyzing the ledger of scaffolding practically and prevent the accident of manager and laborer through the actualization.

This article is about a new law of railroad industry has come into effect in 2004 and that left the railroad company operated under the private system. Accordingly, it has to encounter a variety of managers on the railroad safety part too. Incheon Airport Railroad that was, from Incheon International Airport to Kimpo Airport, opened to traffic on the 23th March, 2007 as the first private railroad company in Korea. This railroad company is working hard to be a safe and convenient airport railroad. There is not operated an effective emergency response that the railroad company and the emergency response personnel without standard operation procedure, recently. The original emergency manual and the emergency procedure of the synthesized railroad safety development business. I am proposing to establish the emergency response scenario according to the different situations that the train operator.
