Since 2015, Euro-NCAP and C-NCAP have enhanced regulation on submarine of rear female passenger. This submarine regulation is a big obstacle to achieve the highest level crash performance. So the objective of this study is to develop new technical way to protect rear female passenger against submarine. In this study, we figured out how design factors of seatbelt affect submarine of rear female passenger by sled test. And we verified that rear passenger submarine can be improved by increasing intersection angle of seatbelt anchor and rotation amount of seatbelt buckle. Based on these results, this paper proposes a new invention of seatbelt buckle and anchor that can improve rear passenger submarine. One is seatbelt buckle that can be detached from stopper to prevent rotation and the other is seatbelt anchor that can be changed the structure so as to incline forward during crash. Finally we proved that submarine of rear female passenger can be improved by the effectiveness of new inventions.

Objectives: The purpose of this study is to identify risk behavior related to the school accident between male and female elementary school students. Methods: 838 School accident data provided by Seoul School Safety Council were analyzed by gender. Based on the results above, survey questionnaires on characteristics of school accident were developed. Self-reported data were collected from a sample population of 433 students in grade 5 to 6 students attending 4 elementary schools in Seoul. Results: The students who answered they experienced the accident in school for the past 1 year, accounts 60.5% of male and 39.5% of females students, which has statistically significant difference. The male's cases happened most around corridor/door, while female's cases happened most in the playground/gymnasium. As for the accident risk behavior, male students had the risk behavior by using the personal belongings/toys, while the female students had much risk behavior related to physical facility/playground. When classifying the characteristics of risk behaviors according to the accident causes, male students showed higher score in the accident risk behaviors related to play/fight than in those of the female students(p<0.05). Conclusions: Health care providers should develop school safety programs by characteristics of risk behavior between male and female elementary school students.

The government operates autonomous safety management activities in the regulated safety management in order to prevent industrial accidents. On the other side, companies are promoting safety management in the workplace, such as improving the safety level of the safety system, but the major reason for the accidents is safety ignorance in the event of big accidents. This study aims to improve the safety culture level by analyzing the difference in safety culture among six workplace sites in the manufacture of food products and drawing the improvement point. The main result is as follows. In order to enhance the safety level of the safety system, it is necessary to minimize the number of systems to be implemented, and to strengthen the small safety management activities that workers participate directly in the workforce, and the incentive policy for the promotion of the safety management activities should be coordinated by each group. Due to the high proportion of female workers, the proportion of female workers should be encouraged to actively participate in the safety of women, thereby improving safety culture levels and improving safety awareness through customized safety education. By learning work procedures through theory and practice, the level of safety culture should be increased. Employees voluntary safety participation activities should increase the level of mutual safety culture. Depending on spontaneous safety participation activities, one should promote safety culture enhancement activities by enhancing the safety level of the safety culture and enhance safety culture through safety awareness, and promote safety culture and procedures for improving safety culture.

Of many volatile organic detergents for metals, benzine(CAS No. 8030-30-6), of which the toxicity has not yet been proven, has been used as an alternative of the halide compounds in the consideration of toxic effects, global warming and the destruction of ozone layer. In order to evaluate the effects of the benzine on human body by investigating the subchronic inhalation toxicity, to obtain the basic data for establishing the criteria of exposure in working environments and to classify the hazardousness in compliance with the Industrial Safety and Health Act by evaluating the hazardousness, repeated inhalation exposure test was carried with SD rats. The rats were grouped by 10 females and males each. The repetitive inhalation exposures were carried out at 4 levels of concentration of 0 ppm, 60 ppm, 300 ppm, and 1,500 ppm, for 6 hours a day, 5 days a week, for 13 weeks. The results are described hereunder. 1. No death of the animals of the exposed and controlled groups in the test period. Not any specific clinical symptoms, change in feed intake quantity, abnormality in eye test, or change in activity were observed. 2. In the 300 ppm and 1,500 ppm groups, weight reduction in the female groups and weight increase of liver and kidney in the male groups compared with control group were observed with statistical significance(p<0.05). 3. In the blood test, the HCT increased in the male 300 ppm group and the number of hematocyte increased, MCV and MCH decreased in the male 1,500 ppm group. In the female 1,500 ppm group, the HB decreased and the distribution width of the hematocyte particle size increased. In the blood biochemistry test, the TP in the male 1,500 ppm group and the LDH in the female 1,500 ppm group were increased with statistical significance(p<0.05). 4. Under the test conditions of the present study with SD rats, the NOEL was evaluated to be from 60 ppm to 300 ppm for both male and female groups. By extrapolation, the NOEL for human who work 8 hours a day was evaluated to be from 128 ppm to 640 ppm 5. Since the NOEL evaluated in this study do not exceed 60ppm(0.184 mg/L) the test material does not belong to the classification of the hazardous substance "NOEL${\leq}$0.5mg/L/6hr/90day(rat), for continuous inhalation of 6hours a day for 90 days" nor to the basic hazardous chemical substance class 1(0.2 mg/L/6hr/90day(rat) defined by the GHS which is a criteria of classification and identification of chemical compounds. However, considering the boiling point($30-204^{\circ}C$), flashing point($-40^{\circ}C$), vapor pressure(40 mmHg), and the inflammable range(1.0 - 6.0 %), sufficient care should be taken for handling in the safety aspects including fire or explosion.

Objectives: The purpose of this study analyzes the characteristics of safety education in schools, experience of accidents, and safety awareness level of elementary school students. It also presents realistic guidelines for safety education, which can effectively lead to the safety behavior of students. Methods: We carried out questionnaire survey by convenient sampling method to 6th grade students of 3 elementary schools in Gyeonggi-do area that can understand the questionnaire and express their own opinion for safety awareness from February 15, 2013 to February 1, 2013. We used a self-administered questionnaire and analyzed 266 questionnaires except dishonestly answered 34 questionnaires. Results: 1. For accident occurrence by gender, male students was higher than female students. Male students was also higher than female students among students having an accident(${\chi}^2$=5.142, p=0.029). There was statistical significance in accident occurrence by how they go to school. Students going to school on foot have higher accident rate(${\chi}^2$=11.447, p=0.010). 2. In terms of safety awareness level, students having no accident was higher than students having an accident(F=3.828, p=0.005) and students usually keeping safety rules have higher safety awareness(F=14.285, p=0.000). 3. When parents give safety education to their children as often as possible, the safety awareness level of students was high(F=5.257, p=.006). 4. Students having an accident have no safety education experience than students having no accident(p<0.05). They have never had safety education from a health teacher. There was statistical significance(p<0.01). Conclusions: Accordingly, we need to make students have safety attitude to prevent safety accidents. To achieve it, safety awareness has to be inspired. Systematic and various education programs that can give connected education with local community network to the students and parents is required.

This study was conducted to assess food safety knowledge of college students according to mass-media reports. To accomplish this, a survey was conducted to investigate the reliability, of primary mass-media sources on Bovine Spongiform Encephalopathy(BSE) as well as the preferences of college students. The most common sources of media consumed by male and female students were terrestrial television(TV)(60%), the internet(21%), and newspapers(11%) and terrestrial TV(60%), newspapers (18%), and the internet(17%), respectively. The preferences for media of major and non-major students were terrestrial TV(64%), newspapers(17%), and the internet(14%) and terrestrial TV(51%), the internet(22%), and newspapers(19%), respectively. The reliability of media as viewed by male students were as follows: terrestrial TV(53%) and the internet(40%), whereas for female students, these values were terrestrial TV(55%) and the internet(37%). The reliability of media as viewed by major and non-major students was as follows: terrestrial TV(67%) and the internet(28%), and terrestrial TV(44%) and the internet(44%), respectively. In the case of male students, the primary sources for information regarding BSE were terrestrial TV(54%) and the internet(38%), whereas for female students, the primary sources were terrestrial TV(57%) and internet (37%). In the case of major students, the primary sources for information regarding BSE were terrestrial TV(52%) and the Internet(40%), and for non-major students, the internet(47%) and terrestrial TV(39%). Both male and female students were found to have less knowledge regarding prions, SRM(Specified Risk Materials), MM(methionine-methionine) type genes, and cow above 30 months associated with BSE compared to the other factors associated with this disease. The BSE-related knowledge held by major and non-major students was revealed unknown more than the majority of responses. Based on these results, greater effort should be made to provide meaningful information to improve the food-safety knowledge of college students according to mass-media.
