  • This study applied the User-Centered Design(UCD) to develop effective VR safety training content for specific users. The UCD-based design was tailored to the VR, facilitating efficient design activities. The UCD process comprises key activities: deriving design concepts from user needs, designing with VR features, developing prototypes, conducting comprehensive evaluations with experts and users, and completing the finals. Unlike traditional UCD, this flexible approach allows iterative cycles, enhancing the quality and user satisfaction of VR safety training contents.

  • With the changes of industrial structure, contents and types in hazardous and dangerous works have been changed considerably. However, the hazardous and dangerous works by defined "Regulation for the hazardous and dangerous work employment restriction" and "Special education for safety and health"have not been amended over twenty years. This study aimed to identify the recent trends of the works by analyzing the death accidents cases from 2004 to 2013 and to present the management methods about future hazardous and dangerous works. The results showed that amount of 1,972 cases among 11,513 death accidents were equivalent to the works presented by "Regulation for the hazardous and dangerous work employment restriction". The amount of death accidents in 'Work of using construction equipment following construction machinery management act' was biggest among the death accidents cases and that of 'Work of handling pressure vessels following high-pressure gas safety control act' didn't show up. For the works in "Special education for safety and health"amount of 1,650 death accidents cases were equivalent. The amount of death accidents in 'Work involving a crane with a capacity of 1 ton or more or work which is carried out with a crane or hoist with a capacity of less than 1 ton in a workplace having at least 5 such machines' presented by "Special education for safety and health"was biggest. Also, death accidents case didn't occurred in three works presented by "Special education for safety and health". It was analyzed that works with low death accidents cases should be needed to study thoroughly the whole disaster research involving nonfatal accidents. Through this study, it was expected that regulation can be operated practically in the industrial field. Also, it is considered to increase

  • This study examined the relative effects of education and eco-IVIS(in-vehicle information system) to reduce fuel consumption and greenhouse gas emissions. Also the study investigated the increasing of driving workload when drivers interact with intervention technique. Thirty participants randomly assigned into two groups(training and eco-IVIS) and conducted driving before and after the each intervention technique. While driving, we observed three driving behaviors: Frequency of excessive RPM, percent of speeding, and mean fuel efficiency. Also the Driver Activity Load Index was used to rate participants' subjective ratings of driving workload. Although the results showed positive impact of both education and eco-IVIS to increasing the eco-driving behaviors, eco-IVIS was more effective than education. However, we found comparable level of driving workload in the education and eco-IVIS.

  • 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.

  • As high-tech science has developed, the need of semiconductor is required constantly. However, there are many processes which use a great deal of poisonous gas in the semiconductor process, so the dangerousness by a gas leak is latent in these processes. Especially, the accident of toxic gas is almost made by ammonia and chlorine. Therefore this report estimates the damage by the leak of ammonia and chlorine used in LPCVD system.

  • As the industrial society is highly developing, human need in daily life has also changed drastically. With the introduction of 40 hour working week system, more households enjoy picnics on weekends. More gas accidents take place on Saturdays and on Sundays than any other days of week. In this context, the Institute of Gas Technology Training in Korea Gas Safety Corporation carries out explosion experiment to make trainees to take all possible measure to ensure safe management of gas in the field by fully recognizing the hazards of gas explosion accidents. In this study, the influence of explosion over-pressure caused by the rupture of butane can thrown away after use was calculated by using the Hopkinson's Scaling Law and the accident damage was estimated by applying the influence on the adjacent people into the Probit model. The value of those away from 50 meters from the explosion site was 1.35kPa and the peak overpressure to thoes away from 25 meters directly was 3.2kPa. Those value was input to the PROBIT model, the estimation showed the sante result 0 percent of damage possibility.

  • Objectives: Electronic cigarettes are battery powered devices that convert a nicotine-containing liquid into an inhalable vapor. The device aerosolizes nicotine so that it is readily entrained into the respiratory tract, from where it enters the bloodstream. Information on the safety of E-cigarettes is required. Methods: Seventeen articles on studies analyzing toxic substances in the liquid and gas phases of electronic cigarettes were reviewed. Results: Tobacco-specific nitrosamines, bis(2-ethylhexyl) phthalate, formaldehyde and acetaldehyde, known to be carcinogenic agents in humans or animals, were detected in the liquid and gas phases. In addition, diethyl phthalate, acetone, ethanol, cresol, xylene, propylene, styrene, triethylene glycol, tetraethylene glycol, pentaethylene glycol cis-3-hexen-1-ol, methyl cinnamate and undecane were identified in the liquid and gas phases of E-cigarettes. Propylene glycol, glycerin, 1-methoxy-2-propanol, 1-hydroxy-2- propanone, acetic acid, 1-menthone, 2,3-butanediol, menthol, carvone, maple lactone, benzyl alcohol, 2-methyl-2-pentanoic acid, ethyl mantel, ethyl cinnamate, myosamine, benzoic acid, 2,3-bipyridine, cotinine, hexadecanoic acid, and 1'1-oxybis-2-propanol were detected in the vapors of E-cigarettes. Conclusion: The hazardous compounds identified in the liquid and gas phases of E-cigarettes should be controlled for the lowest concentrations in the raw materials and production procedures.

  • 주방 등에서 사용하는 식칼은 음식물을 절단하는 경우 음식물이 식칼에 달라붙어 잘 떨어지지 않는 문제를 가지고 있다. 이로 인하여 식칼과 음식물이 쉽게 분리되지 않아 조리작업 및 조리시간이 많이 소요된다. 따라서 조리작업 및 조리시간을 단축하기 위하여 식칼에 음식물이 붙지 않아야 한다. 본 논문은 주방에서 사용하는 식칼의 문제점을 RPS-TRIZ를 활용하여 해결하였다.

  • LPG(Liquefied Petroluem Gas) Vehicles in metropolitan area being applied to improve air quality and have been proven effective for the reduction of air pollution. These gas stations are required to safe the storage tank because of possibility of causing huge loss of life and property. While storage tanks above ground have potential risk of explosion if fire breaks out and those under-ground are difficult to inspect due to poor accessibility neither above nor under-ground tank can serve us well. This study used the RPS-TRIZ (Rapidly Problem Solving-Teoriya Resheniya Izobretatelskikh Zadatch) technique and suggested the use of under-ground containment storage tank as a solution for safety issues and safety inspection.
