Korean aviation authority required air service providers to submit public disclosure of aviation safety investment to encourage proactive and voluntary safety investments. In 2023, two airport operators and seventeen airlines disclosed their safety investment results and plans for the first time. This study aims to examine and analyze the current status of the disclosure system, identify insights for its development, and set directions for the future. Safety investments by airport operators decreased by 14.3% in 2022 compared to 2021 due to decreased aviation demand. Airline increased their safety investment by 46% to 4 trillion won, investing heavily in MRO and aircraft replacement, leading to a decrease in the average fleet age by 0.8 years. FSCs have shown a significantly higher level of safety investment compared to LCCs. However, LCCs show higher safety investment relative to revenue. It is necessary to consider the characteristics of each operator as well as the scale when comparing safety investments. A roadmap is suggested based on the importance of disclosure items for the strategic approach and improvement measures for the aviation safety investment disclosure system.

These days, the interest in the gas safety management has been increasing in our society, It needs the estimates to later investment in points of the gas safety management investment for prevention costs from gas accidents. It is written the general concept of gas safety management and the items that should be invested under the current policy. However they are not defined clearly and We have lots of difficulties in adapting them to actual spots and understanding them by their carry-out. When it follows the current safety standards, they doesn't meet the possibilities of mutual comparison, because gas safety management investment's definition is different. And sufficient information is not supported to efficiency adjudication of gas safety management investment. In this paper, you can find that Gas safety management is defined in order to more effective gas safety management investment, and the Socioscentific approach method was used to decide the gas safety management items that shall be invested.

Disaster and safety budget can be characterized as a large-scale public asset on which the government has a significant role. It is of a crucial importance to properly allocate the limited national budget to various areas as necessary. Higher investment efficiency of the budget related to disaster and safety management requires distribution criteria based on relevance and efficiency. Currently, the budget related to disaster and safety management is orchestrated through the prior consultation system. However, there is still no clear framework for reviewing the investment direction and setting the priority investment areas by prior consultation. This study analyzes the status and characteristics of disaster and safety management projects by damage type and proposes a structured system for prioritization. This framework can be useful in selecting the areas that need priority investments by damage type of disaster and safety management projects, thereby contributing to improving investment efficiency.

Cost-benefit analysis was investigated to propose the analysis method of the effect of investment and the optimum investment level of safety management cost for preventing gas accident in the B governor station. From five classifications of safety management costs consisting of cost items with similar characters and potential accident costs calculated by risk assessments(FMEA/HAZOP), we found that the order of the benefit(the reduction cost of the potential accident cost) was the instrument increase and repair cost > the safety checking and inspection cost > the labor and training cost > the safety equipment and corresponding cost > the research and development cost. As the benefit was increased with increasing the investment cost, the effect of investment was increased with decreasing the Investment cost. As a result, the optimum safety management cost was estimated and the investment level was analyzed by the model of optimum investment level.

The investment for industrial disasters prevention can not help but get accomplished in negative way. At this point, the most effective way to diminish industrial disaster outbreak is the very subject should strive to prevent it by itself However, it's still the times that we place more weight on economic development no economic subject would not positively self-participate in it for the investment for industrial disasters prevention without my effect of numerical reduction. In this view, this study will tv to entirely analyze and grasp the economic toss due to industrial disasters at construction sites, and will present the most suitable safety-investment. As a result, in domestic construction sites, averagely $1.6\~2.6\%$ of the entire construction expenses had been invested for safety expense. The according to the result of the analysis, basically this safety investment expenses should be spent $2.4\%$ over to reduce the saffey-accidents stably.

Korean government announced long-term railway safety investment plan for the safety improvement by 2020. But no research have been done about differential analysis on railroad safety investment and safety improvement. In this study, recent 10 year data on safety investments and accident data are analysed for the differential analysis. Three main safety investments are analysed on regard to accident rate and accident fatalities. Three safety measures include level crossing accident, platform fatalities, and track trespass fatalities. About 90% of railway accident fatalities are caused by these three kind of accidents. Differential analysis shows about 4 to 6 years delay after railroad safety investment and safety improvement. This result can be utilized for the decision making on safety measures and safety target. Which required long term approach.

There are many investment budget drafts in the filed of a road traffic safety. The traffic safety budget is spitted into following three major areas: 1) traffic safety facility (Engineering), 2) traffic enforcement (Enforcement), and 3) traffic safety education & public relation (Education). The three area are known as so-called 3E policy. This study investigates the effect of the investment in the 3E policy on the reduction of traffic accidents analyzing the data annually collected from the 15 local governments during 1992 to 2007. The analysis employing the traffic accidents as the dependent variable reveals that the effect of the investment is higher if same amount of investment is made on areas of the traffic safety education and public relation than the area of facility improvement. The similar conclusions are resulted from the separate investigation of traffic accidents data by 6 different types. All the results consistently indicate that the current traffic safety investment being primarily made on traffic safety facility needs to shift to the areas of traffic safety education and public relation budget.
