This study aims to provide basic data for food hygiene safety education by surveying the status of food hygiene safety awareness, attitude, and personal hygiene control of male and female college students in South Chungcheong Province, Republic of KOREA. From May 16 to June 30, 2019, 1,048 survey responses were collected at H University and analyzed statistically using SPSS 23.0. This study found males believed agricultural, livestock, and fisheries products (3.37, 3.08), and processed foods (3.40, 3.00) to be significantly safer, and information on food safety was easier to obtain (3.40, 3.00) than females. They were also more confident in choosing safe food (3.30, 2.97), than females. This indicates that males are more aware of food hygiene safety than females. On the other hand, females responded that they checked the expiration date (4.11, 4.40) and stored food according to characteristics (4.08, 4.30) than males, wash their hands after using the toilet(4.23 4.53) than males. This suggests that females were more aware of food hygiene attitudes and personal hygiene control than males. According to this study, college students' awareness of food hygiene safety and attitude, personal hygiene control showed a gender gap. Males had higher food hygiene safety awareness than females, but their awareness of food hygiene attitudes and personal hygiene control was lower. This suggests that differentiated food hygiene safety education is needed considering these gender differences.

This study developed an electric power propulsion personal watercraft by combining a battery and an electric system from the domestic automobile industry with water motorcycle from marine leisure industry in a convergence of technology. It also developed a safety inspection plan and type approval standard for personal watercraft that use electric power propulsion. For the registration and production of the electric power PWC (Personal Watercraft), a safety inspection standard (draft) and type approval standard (draft) have been established. PWC that use this electric power propulsion certification standard have been divided into two categories according to the use of gasoline engines as related to the ship's electrical system. The contents of these safety inspections standards is divided into 7 categories, and their purpose is to confirm the facilities used for the safe operation of PWC. Type approval is divided into 7 categories and is intended to ensure the safe production of PWC. This is basic data can be used to establish criteria for safety inspection and type approval of electric power propulsion vessels and to guide the production of the environmentally friendly PWC in Korea.

This study was conducted to examine the usage effects of an augmented reality head-up display (AR-HUD) system on the risk perception and psychological changes of drivers. To do so, we conducted an experiment to collect the driver response times for vehicles and pedestrians as their risk perception behavior, and used a driving behavior determinants questionnaire consisting of Problem Evading, Benefits/Sensation Seeking, Anti-Personal Anxiety, Anti-Personal Angry, and Aggression factors for collecting the psychological characteristics of the drivers. Thirty drivers were randomly assigned into an in-vehicle AR-HUD using group and a control group. As a result, the Anti-Personal Anxiety and Anti-Personal Angry factors were negatively correlated with the response time for the control group. In contrast, these results were not shown for the in-vehicle AR-HUD system using group. These results indicate that the in-vehicle AR-HUD system may partially induce a relaxation of tension or stress for drivers with a high level of interpersonal anxiety. Therefore, the in-vehicle AR-HUD system might contribute to not only the visual safety driving behaviors of drivers, but also to their psychological driving safety with specific characteristics.

This study was carried out to investigate the children's knowledge, attitudes and practices of food safety. A total of 355 data were collected from elementary school students. The concern of food safety was moderate in 5 point Likert scale and relatively high correlated with food safety knowledge(r=0.571) and education(r=0.534). The experience and knowledge of terminology on food safety were estimated. The level of food safety was classified into 5 groups and the consideration of food purchase was classified into 3 groups by factor analysis. A few children were aware of the food safety knowledge and could hardly understood English terminology. And the food safety practices were surveyed, and most of children checked with expiration dates and packaging conditions of food. Personal hygiene practice of children was significantly affected by gender, self hygiene evaluation and the knowledge level of food safety. Providing more food safety information affects personal hygiene and the practices of food purchase, so educational programs on food safety for children were required.

Object: we investigated some factors which can affect workers' comprehension of chemical hazard information and their actions to protect themselves from the hazard. Method: Comprehension score of chemical hazard information and the rate of wearing personal protective equipment (PPE) was surveyed for the 109 workers from 15 factories who were exposed to N, N-dimethylformamide. Difference of the worker's comprehension score of hazard information was analyzed by education interval, work duration and the way of occupational safety and health management between self-managed or sub-contracted. Result: Mean comprehension score of N, N-dimethylformamide hazard, which was given as a short quiz composed of 10 "true" or "false" problems, was 65%. Mean percentage of wearing PPE was improved as the education program was done within a month but decreased after 6 months. Eighty seven % of workers got the chemical hazard information from the material safety data sheet placed at workplace. Conclusion: Education interval and comprehension score affected the rate of wearing PPE. The way of occupational safety and health management self-managed or sub-contracted did not affect the workers' comprehension score on hazard information nor the rate of wearing PPE.
