There are several international standards, established by IEC, for RAMS management of railway system. Those int'l standards are described only total RAMS management, but RAM and safety activities have dissimilar characteristics. In this paper, we suggest the separated RAMS architecture with RAM and safety activity for railway signaling system.

This paper presents the motorcycle inspection standards of electrical system, frame & body, lights and speedometers. 187 real-world motorcycles are visually and mechanically inspected according to the developed inspection standards. The non-compliance rate of inspection standards of the lights is 23.7% and main causes are damage, tinting, painting and coloration of head-lamp, number plate lamp, front-rear position lights, stop lamp and direction indicators of motorcycles. Also, 28.4% of motorcycles are dropped from the luminous intensity inspection standard. Motorcycle electrical system cannot be visually inspected. The motorcycle inspections standards are improved reflecting 187 cases of real-world motorcycle inspection results.

The past five years, industrial accidents due to food processing machinery have been occurred 725 cases, injury by the food cutter occurred 390 cases in its. On this study, to prevent food cutter injury, an attempt is made to present the improved documentation of fundamental safety of the food cutter workplace through the injury analysis of food cutter injury and surveys on band saw machine business field. Analyzing the result of 390 cases on food cutter injury, amputation, cut, puncture occupied 75.1 percent (293 cases), compressed occupied 23.3% (91 cases), also it showed constant component without reference to gender, age, scale of work place, service period. In the survey, lack of concentration for workers have been pointed out as the biggest factor in the cause of band saw machine injury. Meanwhile, such as the EU and Japan, whereas presents safety standards about band saw machines that are tailored to each country, on the other hand, South Korea doesn't provide the standards. To prevent the food cutter injury, safety standards need to be established in consideration of amputation, cut, puncture, compressed injury and financial support is required to procure protective equipment at each place of business.

Offshore plants should be managed at a high level of safety condition. Because the offshore plant has cramped space and has difficult access when a fire occurred, a fire can be critical to the plants. LED lighting can reduce the risk of fire by its lower energy consume suitable to intrinsic safety and lower heat radiation that can reduce the possibility of ignition. Also LED has a long lifetime. Though LED luminaire has various advantages for offshore plants, an international standard for the luminaire has not provided because it is new technology. Because there is no international and domestic standard specially provided for the LED luminaire, a guideline is required for developing the LED light and for the future establishment of an international standard. This study was conducted to develop the guideline for LED luminaire for offshore plants. Firstly, relevant standards were analyzed for the guideline. Then we found that there are editorial differences between international standards and domestic standards. So the guideline was developed based on international version and the differences between the domestic and international standard were provided to let Korean developers recognize the differences.

This study was carried out to verify the suitability of GRS(Glass-fiber Reinforced Slag) as natural type landscape stone according to the material property and structural safety performance standards. The structural safety performance of the GRS panel showed 12.4MPa and 16.2MPa each in flexural strength at 2 and 3% content of glass fiber while the flexural strength at 4 and 5% of glass fiber content showed 26.9MPa, and 30.2MPa, respectively, all satisfying the standards. In addition, air-dried gravity was found to be 1.82~1.89 in measuring range at 2~5% level of glass fiber content, satisfy the existing standards 1.8~2.3. In structural safety performance, the range of flexural strength consequent on glass fiber content was surveyed to be 12.8~30.2MPa, all satisfying the performance standards, while 10MPa and more while the compressive strength range was found to be 41.5~53.3MPa, all satisfying the performance standards, 40~60MPa. This study judged the suitability of only the items for a property of matter of landscape stone GRS by applying the natural-form landscape stone GFRC material standard, but in case an installation constructed with GRS material comes into existence later, there should be comprehensive performance guidelines through the research on durability, landscape performance and environmental and ecological performance.

Occupational Safety and Health Act provides that industrial safety helmets are personal protective equipment(PPE) to protect heads against falls from a height. Relevant domestic regulations are distinguished and different from other countries' cases. This study investigated industrial safety helmet's protective purposes and characteristics related to falls and the notion of fall prevention. A comparative analysis of regulations on safety helmets and fall prevention as well as standards on safety helmet's impact test requirements is followed by a literature review. It is also suggested that the term "fall" related to safety helmets should be changed to "impact on the upper part of head" in domestic regulations and standards.

Background: Methodologies for a series of radiological consequence assessments show a distinctive difference according to the design principles of the original nuclear suppliers and their technical standards to be imposed. This is due to the uncertainties of the accidental source term, radionuclide behavior in the environment, and subsequent radiological dose. Both types of PWR and PHWR are operated in Korea. However, technical standards for evaluating atmospheric dispersion have been enacted based on the U.S. NRC's positions regardless of the reactor types. For this reason, it might cause a controversy between the licensor and licensee of a nuclear power plant. Materials and Methods: It was modelled under the framework of the NRC Regulatory Guide 1.145 for light-water reactors, reflecting the features of heavy-water reactors as specified in the Canadian National Standard and the modelling features in MACCS2, such as atmospheric diffusion coefficient, ground deposition, surface roughness, radioactive plume depletion, and exposure from ground deposition. Results and Discussion: An integrated accident consequence assessment code, ACCESS (Accident Consequence Assessment Code for Evaluating Site Suitability), was developed by taking into account the unique regulatory positions for reactor types under the framework of the current Korean technical standards. Field tracer experiments and hand calculations have been carried out for validation and verification of the models. Conclusion: The modelling approaches of ACCESS and its features are introduced, and its applicative results for a hypothetical accidental scenario are comprehensively discussed. In an applicative study, the predicted results by the light-water reactor assessment model were higher than those by other models in terms of total doses.

This is a qualitative case study conducted for the purpose of enhancing educational effect of safety education facilities. Recently, the Ministry of Education (MoE) has proclaimed the 7 standards for school safety education, and has established safety education facilities to implement experience-based safety education. This study attempted to explore ways to enhance educational effect of safety education facilities through participatory observation and interview conducted with personnel of several facilities. The findings of the study were as follows: it was necessary to secure and maintain facilities for the implementation of substantial safety education, to develop and distribute standardized curriculum and materials, and to improve quality of professional instructors. The study suggested implications and future tasks to improve the education effect of safety education facilities in various dimensions.

Currently, the Korean railway standards (KRS), managed by Korea National Railroad, have been managed by the Korean Ministry of Construction and Transportation. According to Korean railway safety law, which were established for the guarantee of railway safety, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute (KRRI). In this paper, the detailed master plan for the management of KRS will be introduced for the effective management of KRS, and KRS management direction for the future will be suggested.
