This research investigates how a Virtual Reality (VR)-based simulation could be used to train safe operation skills for forklift operators. Forklift operation is categorized as high-risk work by many occupational health and safety regulators and authorities due to high injury and fatality rates involved with forklifts. Therefore, many safety guidelines have been developed for forklift operators. Typically, forklift operation safety training is delivered based on instructional texts or videos, which have limitations in influencing people's safety behavior. Against this background, we propose a VR-based forklift simulator that can enable safe operation skills training through a feedback system. The training program consists of several modules to teach how to perform the basic tasks of forklift operation, such as driving, loading and unloading, following the safety guidelines. The system provides instantaneous instructions and feedback regarding safe operation. This training system is based on the model of "learning-by-doing". The user can repeat the training modules as many times as necessary before being able to perform the given task without violating any safety guidelines. The last training module tests the user's acquisition of all safety skills required. The user feedback from several demonstration sessions showed the potential usefulness of the proposed training system.

We carry out a demonstration project to verify performance of a Home- Smart Cabinet Panel(H-SCP) at the child care facility. It is difficult to prevent an electrical disaster using a existing cabinet panel because electrical events are invisible and unforeseeable. So we construct a integrated information system with a Home-Smart Cabinet Panel(H-SCP) for management of low-voltage customers. The integrated information system with the H-SCP maintain the transmitted data from H-SCP, alert a electrical event to a administrator and show a state of customer health in real time respectively. A manager of electrical safety can prevent electrical disaster to maintain electrical facilities after analysis on the integrated information system.

Welding and cutting, which are representative tasks in handling firearms at industrial sites, are the basis for production and maintenance processes across all industries. They are also essential in the root industry. Specifically, they are widely used in the manufacturing industry, including equipment industries such as shipbuilding, automobiles, and chemicals, and subsequent maintenance work and general facility repair. However, such hot work carries a high fire risk owing to sparks scattering and inadequate management, resulting in a high occurrence of accidents. In response, the government and relevant organizations have recently revised the Occupational Safety and Health Act to prevent accidents during hot work. These revisions impose more stringent regulations than before, which are expected to help prevent actual fire accidents. However, whether the fire observer system, which is the core element of the revision, would be practically applied and maintained is unclear. Therefore, this study compared the fire observer system in the revised Occupational Safety and Health Act with those in the laws and systems of developed countries, conducted interviews with safety and health experts to assess the suitability of the new system for fire observer operations, and improvement plans were derived accordingly. Therefore, the laws and systems of developed countries grant more authority to fire observers compared with those of Korea. Moreover, professional training in handling emergency is required. Interviews with safety and health experts revealed that regardless of company size, the same operating standards were applied, and standards for deploying fire observers in various locations were unclear. Furthermore, there was a lack of professional education and training, and the role and authority of fire observers were limited. These findings revealed a problem in this sector. The results of this study are expected to serve as basic data for establishing a practical system for placing fire observers and supplementing laws, guidelines, and systems for preventing fire accidents.

Objectives: The aim of this study was to evaluate gas concentrations such as oxygen in ginger storage tunnels, which are the causes of asphyxiation in confined spaces and suggest directions for safety and health management at ginger farms. Methods: Five farms in the Seosan and Taean areas which use underground ginger storage tunnels were chosen and examined with a walk-through survey and direct reading device for oxygen, hydrogen sulfide, ammonia, and carbon monoxide. Results: The oxygen concentration in the storage tunnels with no ventilation was found to be under 18% in summer, which may cause health effects. The concentration in those with ventilation was about 19%. The difference in temperature by measurement day had little effect on the concentration of oxygen. Conclusions: Even though some of farms had used compulsory ventilation systems, none of the farms visited possessed any direct reading device for oxygen. Warning systems using a direct reading device can be more effective, helpful, and required compared to ventilation, considering the difficulty and expense of periodical maintenance of ventilation systems and the fact that a farmer can be placed in danger when unaware of the malfunction of the ventilation system. In addition, a warning system may make farmers more cognitive of agricultural safety and health actions while a ventilation system can cause them to become passive and ignorant of workplace hazards.

Recently, the government is trying to change the paradigm of occupational safety by enforcing the entire revision of the Industrial Safety and Health Act and the Punishment of Serious Accidents Act with the goal of reducing the occupational accident and death rate by half. In particular, small-scale workplaces with less than 50 employees or less than 100 million won have difficulties in establishing a safety and health management system due to lack of safety and health management competency and lack of will of business owners. Therefore, this study attempted to identify problems and suggest improvement measures through an expert survey on the overall business area of the small business safety and health technology support project, which is one of the government's policies.
