The importance of information security has grown alongside the development of information and communication technology. However, companies struggle to select suitable countermeasures within their limited budgets. Sönmez and Kılıç (2021) proposed a model using AHP and mixed integer programming to determine the optimal investment combination for mitigating information security breaches. However, their model had limitations: 1) a lack of objective measurement for countermeasure efficacy against security threats, 2) unrealistic scenarios where risk reduction surpassed pre-investment levels, and 3) cost duplication when using a single countermeasure for multiple threats. This paper enhances the model by objectively quantifying countermeasure efficacy using the beta probability distribution. It also resolves unrealistic scenarios and the issue of duplicating investments for a single countermeasure. An empirical analysis was conducted on domestic SMEs to determine investment budgets and risk levels. The improved model outperformed Sönmez and Kılıç's (2021) optimization model. By employing the proposed effectiveness measurement approach, difficulty to evaluate countermeasures can be quantified. Utilizing the improved optimization model allows for deriving an optimal investment portfolio for each countermeasure within a fixed budget, considering information security costs, quantities, and effectiveness. This aids in securing the information security budget and effectively addressing information security threats.

The foreign capital of appropriate scale is affirmative in stabilizing the domestic foreign exchange and stock market. But its excessive scale threatens corporate governance by a hostile M&A and causes the out-flow of national wealth and the unhealthiness of finn because foreign investors require high dividend through the superiority of stock ownership ratio. Therefore, the government and corporate must make the defensive countermeasure of corporate governance for the foreign capital immediately.

A HILS(Hardware-In-the-Loop Simulation) technique for an IR guided weapon is proposed. The IR HILS facility functions as a testing unit for a missile guidance and control system to evaluate target acquisition, tracking, and countermeasure performance. The configuration of IR HILS facility, modeling technique of an IR environment including target, background and countermeasure, and test and evaluation procedure are included.

For settlement of safety supervision and prevention agains industry's accident, first, it needs to design and manufacture for safety of machines and tools, second, it must safety foundation of machines and tolls and sticking of safety facilities, third, it must be wear of protective device in operations. Then it needs to fit countermeasure founding and continuous safety education and itself inspection control that analysis and study the point at issue of safety.

The primary countermeasure for environmental stresses of crops grown in Korea would be to maintain top soil content of available B for upland crops and Si for low land rice in balance with other nutrient elements such as N, P and K, so as to maintain those nutrient balances in plants. Development of standard levels of elements in soils for balances uptake of those elements by plants are needed under the multi nutrient factor balance concept using the soil test results.

The AC induced voltage on underground pipelines not only do harm to workers and instruments, but also cause big trouble in some case. This paper gives the mechanisms, examples, and countermeasure for the AC induced voltages which are caused by the resistive coupling between the grounding system of the 22.9kV distribution power system and the underground pipeline.

The speciality of education installation has to be applied to the design construction, inspection of school in the installation. But. it was applied general electric installation standards in korea. Therefore, the electric shock accidents and fire was more frequently occurred in the school than in other building. So, this paper, is proposed the comprehensive countermeasure for safety of school electric installation
