Subcontracting business than the contracting business in shipbuilding industry is a lot of hazardous job and highly accident because of highly work intensity. In order to prevent the accidents, there is a need to analyze characteristic. of shipbuilding, to apply measures of risk assessment. In this paper, I suggested an improvement of the risk assessment through the actual condition research in shipbuilding industry. In the research method, I analysed accidents occurred until 2011-2013. Carried out the actual site survey while two weeks in May 2014. As a result, 1) The main pattern were caught-in or between, fall on the high level according to analyzed accidents. 2) To apply the weight show clear of magnitude for risk assessment. 3) Risk estimation of risk assessment is desirable to be quantization by accidents analysis, and to be greater than or equal to 4 steps.

This study is aimed to improve safety of ladle in the metal products manufacturing industry. Burns may occur from spills, spatters or eruptions of hot metal from ladles during pouring or transporting. According to the statistics of occupational accidents about the ladle, many victims were exposed to or contacted with extreme temperatures. The many fatal injuries occurred as a result of unexpected discharging of molten metal due to tipping over ladles. To prevent ladles from turning over, the trunnion axis shall be located below the center of gravity of the ladle at all operating condition. For this purpose, the equation is proposed to calculate the minimum location of a trunnion axis for definite static stability when tilting.

As people make efforts on accident prevention, the number of accidents has decreased over the years, however the number of fatal major industry accidents has rather increased, which resulted in the increase of the number of deaths in total. Under these conditions, there is an attempt to introduce and perform the safety vocational education system as a means for preventing major industry accidents. Therefore, in this paper, we analyse vocational education of manufacturing industry from the safety's point of view and suggest the efficient techniques measuring and managing each safety management. Proposed techniques show that the specification on safety determines weight through the managers of firms and each process is suggested by using SN ratio.

Investigation and analysis of accidents are critical elements of safety management. The over-riding purpose of an organization in carrying out an accident investigation is to prevent similar accidents, as well as seek a general improvement in the management of health and safety. Hundreds of workers have suffered injuries while installing, maintaining, or servicing machinery and equipment due to sudden re-energization of power lines. This study presents and analyzes two electrical accidents (1 fatal injury and 1 serious injury) that occurred because the power supply was reconnected inadvertently or by mistake.

As people make efforts on accident prevention, the number of accidents is decreasing, fatal major industry accidents are rather than increasing so that the number of deaths has not decreased. Under these conditions, there is an attempt to introduce and perform the safety vacational education system as a means for keeping from major industry accidents. Therefore, in this paper, we analysis vacational education of manufacturing industry in safety point of view and suggest the technique efficiently measuring and managing each safety management. Proposed the technique shows that the specification on safety determines weight through the managers of firms and each process is suggested by using SN Ratio.

A confined space means places where the risk of damage to health caused by lack of oxygen or hazardous gases in inadequate ventilation conditions and the risk of fire and explosion caused by flammable substances. Asphyxiation accidents in a confined space occured every year and also occurred more than two people at the same time. In this study, we surveyed the domestic statistical data occurred the lack of oxygen in confined space for the last 10 years(2006-2015) and, analyzed the accident by industries sector, workplace size etc. 17 fatal work accidents that occurred in confined spaces in Korea between 2013 and 2015 were investigated and analyzed using the database of the KOSHA and suggested interventions to minimize asphyxiation accidents in confined spaces. This paper is expected to be used to establish interventions planning and training as a preventive measures in workplace having confined spaces.

Smart station is a modular one easily installed on the road and protecting from the environmental effects such as snow and rain etc. Smart station can provide some comfortable and easy ambience during waiting the Bimodal Tram. Conventional station can be invaded by overdriven vehicle to make some fatal accident. But smart station gives more protective and safe shelter to the passengers. This paper have investigated and analyzed the structural safety and usefulness about the new conceptual modular smart station.

In manufacturing industry of the modem industrial society, people increasingly become concerned the awareness of safety increasingly although they have regarded production the most important factor. Even though, as people make efforts on accident preventions, the number of accidents is decreasing, fatal major industry accidents are rather thanincreasing so that the number of deaths has not decreased. Under these conditions, there is an attempt to introduce and perform the process safety management system as a means for keeping from major industry accidents. However, it leaves to be desired on the methods of measuring process safety in the general manufacturing industry, while it is available to do that in the chemistry industry. Therefore, in this paper, we analysis processes of manufacturing industry in safety point of view and suggest the technique efficiently measuring and managing each process. Proposed the technique shows that the specification on safety determines AHP weight through the managers of firms and each process is suggested by using normalized matrix.

Previous methods to evaluate the risk of dropped objects rely on personnel experience of the engineer or operator without analyzed data. However analyzing historical statistic data is the best approach to find the safest operation route and to achieve more reasonable and reliable calculation results. By counting the failure frequency and fatal accident rate the risk can be quantified, and so controlled or mitigated with best economical risk reducing measures. This analysis gives a crane operator with useful information for selecting the best crane operation route, and a designer with an estimation of risk level for the dropped objects from a safety point of view.

In this study, temperature sensors were adhered to transformer that is used in KHST(Korean High-Speed Train) to verify variation of temperature characteristics about transformer synthetically and efficiently. In the case that temperature of transformer exceeds reference temperature for running of KHST, overheating of transformer may cause a fatal accident of vehicle. Characteristics and main specifications of transformer in KHST were described in this paper. Also, measuring system for temperature measurement of transformer was explained in brief. Temperature data of transformer was acquired using measuring system, KRRI(Korea Railroad Research Institute) analyzed characteristic in contrast with comparing with temperature of transformer about month, running speed and running time.
