The purpose of this study was to identify the effects of safety education on the safety consciousness and self-efficacy of the emergency response in university students. The study design was single group, pre- and post-test quasi-experimental study. The participants were 63 students who were given 25 hours of safety education including cardiopulmonary resuscitation(CPR). The instruments were the Public Safety Consciousness Index(PSCI) and self-efficacy index. The data were analyzed by the t-test and ANOVA using SPSS 21.0 program, and 1-sample proportions test using the R version 3.02. The results showed that the average percentile score of PSCI was increased significantly from 59.20 to 67.20 which is moderate level. After receiving safety education, one third of the participants were promoted from moderate to excellent level. The average percentile score of the self-efficacy of emergency response was increased significantly from 51.16 to 80.95. The willingness to provide CPR to family(100%) and others(76.2%) were significantly increased. In conclusion, safety education raises the safety consciousness and increase the self-efficacy of the emergency response. Universities are recommended to provide safety-related subjects to encourage students to attain the excellent level of the PSCI. These results suggest that the government renew the PSCI tool, develop a life-cycle specific map for safety education, and provide a monitoring system.

Living in a globalizing society, securing food safety requires collaborations among the various trading parter countries. The food safety level of a country depends on the food self-sufficiency level, domestic consumers’ preferences as well as the food safety level of its trading partner countries. To better understand food safety in a society, it is useful to examine food safety issues in foreign countries. This study aims to understand consumer food safety perceptions and competencies of three countries: Korea, China, and United States. From an online survey of 2,000 consumers from the three countries(1,000 Korean, 500 Chinese, and 500 American consumers), the food safety perception and competency were measured. Among the three countries, American consumers’food safety levels were the highest and Chinese consumers food safety competencies were the highest. Americans perceive the food in their country are generally safe and Chinese consumers’ food safety knowledge, attitudes, and behaviors were food safety perception score for all three countries. The findings also showed differences in better than the other two countries. Food safety competency level scores were higher than the food safe perception on a item-base among the three countries. It is found that the food safety issue is closely related to the society’s current issue, culture, and social system. The research also examined food safety perception and competencies based on demographic and socio-economic characteristics of individuals. The factors that related to food safety perception and competencies were also identified.

This study is to analyze the characteristics of the eroded or deposit sediment using Takahashi's method(1992) based on the Finite Difference Method(FDM), according to the variance of channel slope angle and suppling water discharge. For the case of low slope channel angle, erosion and deposition were occurred alternately at the upstream channel. For the case of high slope angle, erosion was dominant at the upstream channel. Particularly, if the slope angle exceeds 15 degree, which is low limit for the debris flow occurrences, erosion was more dominant than other cases. Whenever water discharge was more supplied into the upstream channel, there was equivalent at the upstream channel compared to low supplying water discharge. This is because the debris flow moves down rapidly to the downstream channel.
