Purpose: The purpose of this study was to evaluate effects of preschoolers' safety education on knowledge, attitude and practice. Method: This is quasi-experimental control group pretest posttest design. They were randomized 50 for experimental group and 50 control group. Intervention was once a week for 10 weeks, from March 10th to July 4th of 2009. The experimental group received 10 sessions of program and the control group received none. After the research was over, the control group also received 10 sessions of safety education program. Result: After received 10 sessions of safety education program, the score of safety knowledge, of the experimental group was higher than before(p<.05). After received 10 sessions of safety education program, the score of safety attitude of the experimental group was higher than before(p<.001). After received 10 sessions of safety education program, the score of safety practice of the experimental group was higher than before(p<.001). The score of safety knowledge, safety attitude and safety practice of the experimental group was higher than that of the control group. Conclusion: In conclusion, 10 sessions of safety education program which developed by the researcher for preschoolers' was proved as the effective safety education program. To improve the preschoolers' safety knowledge, safety attitude, and safety practice, application of the safety education program which developed by the researcher for preschoolers' was recommended.

As the concerns regarding global worming were increased, the pressure of greenhouse gas(GHG) emission reduction on mobile source was also increased. Carbon Dioxides contribute over 90% of total GHG emission and the mobile source occupies about 20% of this CO₂ emission. Therefore automotive exhaust is suspected to be one of the major reasons of the rapid increase in greenhouse effect gases in ambient air. In this study, in order to investigate CO₂ emission characteristics from gasoline passenger cars(PC), which is the most dominant vehicle type in Korea, 106 vehicles were tested on the chassis dynamometer. CO₂ emissions and fuel efficiency were measured. The emission characteristics by displacement, gross vehicle weight, vehicle speed and CVS-75/vehicle speed mode were discussed. Test modes were vehicle speed modes and CVS-75 mode that have been used to develop emission factors and to regulate for light-duty vehicle in Korea. It was found that CO₂ emissions showed higher large displacement, heavy gross vehicle weight, low vehicle speed and CVS-75 mode than small displacement, light gross vehicle weight, high vehicle speed and vehicle speed mode, respectively. From these results, correlation between CO₂ emission and fuel efficiency was also determined. The results of this study will contribute to domestic greenhouse gas emissions calculation and making the national policy for climate change.
