The charge and discharge current in EPR(Ethylene Propylene Rubber), which were irradiated with the radiant capacity of 0~600 ［kgy/h］, have been measured in order to investigate the influence of the atmosphere (oxygen, air and vacuum) on electrical properties. It has been shown that the charge and discharge current increase as the amount of radiant capacity increases in air and vacuum atmosphere. This electrical property degradation can be speculated due to that the C＝O radicals or impurities, which comes from during shaping process, may act as dipoles. On the other hand, the charge and discharge current are shown to be higher in the amount of 1［kgy/h］ than these in 10［kgy/h］ in air atmosphere, because the charge and discharge current can be increased as the exposure time is extended with slower rate. Under the same amount of irradiation, the charge and discharge current in oxygen atmosphere are shown to be higher than those in vacuum. This is possibly due to that the main chain can be broken by oxidation when it is exposed to the $\gamma$ -rays.

In order to prevent fire and explosion due to the electrostatic discharge at the Gas Station etc. This result will be applied to standard in the future. Wearing the non-electrostatic removing wear, Charged voltage of human body is 3,980V(MIE is approximately 0.79mJ). There is a possibility of fire explosion because the MIE of LP gas is 0.25mJ. In accordance with using period(whasing times), Charged voltage is shown that propensity is increased. Electrostatic charge amount is upper standard($0.6{\mu}$C) of the hazard of electrostatic removing wear. There is a possibility of fire and explosion. Therefore, countermeasure and management are needed about gas station worker.

The study on industrial accidents in Korea has been focused on frequencies of each type, severity, characteristics, causes, and so on. Those attributes of industrial accidents were usually analyzed independently, so that it was hard to provide a systematic guidelines for efficient safety management. Therefore, there were a few of studies based on comprehensive survey results in terms of characteristics of safety management. This study aimed to figure out the characteristics of current safety management and to provide a guideline for ideal safety management in industry. The questionnaire survey carried out for the workers(695) who were in charge of safety management at their industries. The multivariate analyses as well as descriptive statistical analysis were conducted. The factor analysis showed that there were three factors of safety management. They were 1) investment and management for accident prevention, 2) safety manager, and 3) general health and environmental condition. The industries of respondents were clustered into three groups. Three groups showed a statistically significant differences on the number of cases reported and the trends of accident. Actually, the group with the larger investment and better management of accident prevention had a smaller number of accident cases.

In construction work, safety accidents often occur in combination with unstable physical and human conditions during preparation and execution of work. In Korea, the accident rate is higher to that of any country in the world. Therefore, it is necessary to take measures by fundamental prescription. In this paper, in the case of construction safety management, we tried to find a reasonable alternative through a questionnaire survey to apply to subcontracting and small-scale construction. In conclusion, workers who are well aware of the task could be able to reduce the accident rate by deploying them as safety management officers after receiving the training.

Despite a general acknowledgement of the importance of thorough needs analysis, a lot of training and education programmes are not considering needs analysis. When it is actually done, needs analysis is often trial and error or conducted in a fairly ad hoc manner. we are feel to needs for systematic approach to training and education needs analysis. We investigated the training and education needs for safety management system of railway manager. railway manager is just object to safety management team. we are develop to questionnaire design for safety management system in railway safety management. The questionnaire is separate to expert and a staff in charge related railway safety. We are discusses to primary needs safety management system in railway management team, and proposed to adapting training needs analysis method in railway safety.

Purpose : The aim of this article is to describe the nurses' experiential learning mechanism on patient safety. Methods : To analyze nurses' learning experiences on patient safety cases, a focus-group interview method was used. The Kolb's experiential learning model was used as a reference model. Findings : Without deep reflective reasoning about specific experiences, there is no creative or innovative solutions to experiment actively. Nurses are likely to be reluctant learners when there is no systemic support from formal departments which is in charge of patient safety and quality of care. Conclusion : In order to build patient safety culture in hospital, there should be efforts to make nurses as active learners on patient safety as well as to build learning environments in medical units.

Conventional submarine propulsion batteries have mainly used lead acid batteries, which have proved relatively safe, but in recent years, research on mounting lithium-ion batteries to improve the underwater operation capability of submarines is underway in advanced countries such as Japan. Korea has world-class technology in the development of electric vehicles and lithium-ion batteries for energy storage, but fire safety accidents continue to occur in electric vehicles and energy storage lithium-ion batteries. In order to mount the lithium-ion battery in a submarine, it is necessary to check the safety as well as whether the performance is improved compared to the lead acid battery. Through the charge/discharge experiment of this lithium-ion battery module unit, it was possible to measure how much performance was improved compared to the lead acid battery. Safety tests were conducted on the lithium-ion battery module assuming that it was mounted on a submarine, and it was confirmed that safety was secured when applied to a submarine. Since many modules are mounted on actual submarines, it has been confirmed that it can be applied to submarine systems by simulating charge/discharge characteristics through Hardware-in-the Loop(HILS). Through the results of this study, the application of lithium-ion batteries to submarines is expected to significantly improve the sustainability of underwater operations.
