The KORAIL is managing the preemptive safety verification system along with the operation of the safety management system from the planning stage to meet the increased customer expectations and stop safety concerns of main-line railway customers. Therefore, this study examined Safety certification system, safety management indicators, targets of the European railway and judged the effectiveness of the safety verification system by comparing the Korean railway system of certification procedures and standards of safety activities. It also seeks the development direction of qualitative and quantitative activity-based improvements and suggestions such as validation of planning and classifying incidence of the incident/accident in execution phases. Through the introduction of safety verification system, measures were investigated which can be used as a barometer of the cost-benefit effectiveness for safety disaster prevention, SMS management indicator analysis and feedback.

This research was conducted under the pre-post test control group design, administering the pre-post testing to both the experimental and the comparative groups. The experimental group was subjected to Practical Reasoning Instruction in Home Economics: whereas, the comparative group was taught under the lecture-Instruction in Home Economics. The research findings are as follows: 1. Those who studied Home Economics under the practical reasoning method scored higher on the critical thinking process than the comparative group students who were taught Home Economics in the lecture-style approach. 2. The experimental group of students, who studied Home Economics under the practical reasoning method, scored higher than the comparative group in their ability to perceive assumption and to render judgment among the five sub-factors of their critical thinking processes.
