Purpose：This thesis was performed to evaluate the effect of the experience safety education on the safety behavior and standard of habit to the middle school students of one islands. Methods：The participants of this study included 43, located in the adjoining region in S county. While one of the class, composed of 19 students was designated as an experimental group, and the other class, composed of 24 students, was compared as a control group. Used program in this study was safety education program, 'Safe School, Safe Life' which was developed by Korea Occupational Safety & Health Agency. This program has emphasis on the virtual case rather than lecture style education. Results：The findings in this research were as follows. Indoor safety behavior was significant difference between the two groups. On the other hand, the effect on outdoor safety behavior was not difference. In playground case, active strength was needed without continuous attention. The effect of the experience safety behavior education was not shown in the area of traffic rules, pedestrian safety, and vehicle safety. But home safety behavior was effective. Education program on the manners of standard life habit gives positive results. But in the area of rules, this program was not effective, since students had tendency to emphasize the rigid scale rather than manners. Conclusion：These findings in the study give us the necessity of experience safety education program to prepare various situations of everyday life and to reinforce safety behavior and improve standard life habit.

This pilot study was performed to produce data of the Children's Dietary Life Safety (CDLS) Index which is required by the Special Act on Safety Management of Children's Dietary Life and to evaluate the CDLS Index for 7 metropolitan cities and 9 provinces in Korea. To calculate the CDLS Index score, data regarding the evaluation indicators in the children's food safety domain and children's nutrition safety domain were collected from the local governments in 2009. For data regarding the indicators in the children's perception & practice domain, a survey was conducted on 2,400 5th grade children selected by stratified sampling in 16 local areas. Relative scores of indicators in each domain were calculated using the data provided by local governments and the survey, the weights are applied on relative scores, and then the CDLS Index scores of local governments were produced by adding scores of the 3 domains. The national average scores of the food safety domain, the nutrition safety domain and the perception and practice domain were 23.74 (14.67-26.50 on a 40-point scale), 16.65 (12.25-19.60 on a 40-point scale), and 14.88 (14.16-15.30 on a 20-point scale), respectively. The national average score of the CDLS Index which was produced by adding the scores of the three domains was 55.27 ranging 46.44-58.94 among local governments. The CDLS Index scores produced in this study may provide the motivation for comparing relative accomplishment and for actively achieving the goals through establishment of the target value by local governments. Also, it can be used as useful data for the establishment and improvement of children's dietary life safety policy at the national level.

The more the lift environment eastern idea, culture, factory automation system and information technology complicates, the more the various human error brings about. It brings about all kind of accidents and occupational diseases. Also the death and sickness or injury by psychological stress among the human error has increased every year. Therefore this paper describes the Korean lift change unit model through statistical testing with the proposed life change unit factors on the married workers living the middle area. The proposed model can be simply used in order to minimize the industrial accident and human error in real fields. Finally, the result will be helpful for the better safety management.

Life Cycle Cost(LCC) is adopted to decide the target of safety level in designing suspension bridges. The LCC are evaluated considering two types of uncertainty; aleatory and epistemic. The nine alternative designs of suspension bridge are simulated to decide the safety level which can minimize the LCC. The LCC is calculated through the probability of failure and safety index including the uncertainty. This method results in the useful tool deciding the optimum safety level with minimal LCC as the main design factor.

Because a variety of factors affects children in the development process in order to act practice of life safety behaviors aggressively, this study examined the relationships among academic stress, self-esteem and practice of life safety behaviors of school-age children. Data was collected through a self reported structured questionnaire from 510 Korean school-age children using convenient sampling methods from April 1 to 30, 2013. Stepwise multiple regression revealed the Help of safety education (${\beta}=.254$, p<.001), academic stress (${\beta}=-.222$, p<.001), grade(${\beta}=.201$, p<.001), gender(${\beta}=-.180$, p<.001) to be significant predictors of practice of life safety behaviors of school-age children. These variables accounted for 23.9% of practice of life safety behaviors. Therefore, to facilitate the practice life safety behaviors in school-age children, academic stress needs to be decreased by efficient management and intervention.

The purpose of this study is to analyze the safety needs and life satisfaction of users of security system. The contents of the questionnaire consisted of "safety need, use satisfaction, life satisfaction". As a result of the analysis, Chronbach's alpha coefficient was calculated as 0.897 for safety needs, 0.888 for use satisfaction, and 0.887 for life satisfaction. The items were found to have internal consistency. In the validation of discriminant validity, both AVE and CR values were found to be 0.6 or more than the reference value of 0.8. The intuitiveness of the variables used in this study was found to be largely secured. As the hypothesis test result, the standardization factor was calculated as 0.993 for 'safety needs ⇨ use satisfaction' and 0.453 for 'use satisfaction ⇨ life satisfaction', and both hypotheses were positive. As a result of the verification, it was analyzed that the higher the user's safety needs, the higher the use satisfaction, and the higher the use satisfaction, the higher the life satisfaction.

The government has been constructing and supplying public rental housing to ordinary people in order to stabilize housing since 1989. However, the public rental houses initially supplied to ordinary people are at high risk for safety accidents due to the deterioration of the facilities. Therefore, this study is aimed to propose a solution to solve the life safety hazards of the old rental housing complex as a follow-up study of Analysis of Accident Patterns and Hazard Factor for Life Safety in Rental Housing Complex. Types of life safety accidents that occur in public rental housing complexes are sliding, falling, crash, falling objects, breakage, fire accidents, traffic accidents and criminal accidents. The types of safety accidents that occur in rental housing complexes analyzed in this study are sliding, crashes, falling objects, and fire accidents. Although the incidence of safety accidents such as falling, breakage, traffic accidents and crime accidents in public rental housing complexes is low, these types are likely to cause safety accidents. The method of this study utilized interviews and seminar results, and it suggested ways to solve the life safety hazards in rental housing complexes. Interviews were conducted with residents and managers of rental housing complexes. Seminars were conducted twice with experts in construction, maintenance, asset management, housing welfare and safety. Through interviews and seminars, this study categorizes the life safety hazards that occur in rental housing complexes by types of accidents and suggests ways to resolve them as follows. (1) sliding ; use of flooring materials with high friction coefficient, installation of safety devices such as safety handles, implementation of maintenance, safety inspections and safety education, etc. (2) falling ; supplementation of safety facilities, Improvement of the design method of the falling parts, Safety education, etc. (3) crash ; increase the effective width of the elevator door, increase the effective width of the lamp, improve the lamp type (U type ${\rightarrow}$ I type), etc. (4) falling objects and breakage ; design of furniture considering the usability of residents, replacement of old facilities, enhancement of safety consciousness of residents, safety education, etc. (5) fire accidents ; installation of fire safety equipment, improvement by emergency evacuation, safety inspection and safety education, etc. (6) traffic accidents ; securing parking spaces, installing safety facilities, conducting safety education, etc. (7) criminal accidents; improvement of CCTV pixels, installation of street lights, removal of blind spots in the complex, securing of security, etc. The roles of suppliers, administrators and users of public rental housing proposed in this study are summarized as follows. Suppliers of rental housing should take into consideration the risk factors that may arise not only in the design and construction but also in the maintenance phase and should consider the possibility of easily repairing old facilities considering the life cycle of rental housing. Next, Administrators of rental housing should consider the safety of the users of the rental housing, conduct safety checks from time to time, and immediately remove any hazardous elements within the apartment complex. Finally, the users of the rental housing needs to form a sense of ownership of all the facilities in the rental housing complex, and efforts should be made not to cause safety accidents caused by the user's carelessness. The results of this study can provide the necessary information to enable residents of rental housing complexes to live a safe and comfortable residential life. It is also expected that this information will be used to reduce the incidence of safety accidents in rental housing complexes.

The Safe Life is an essential subject of education introduced in the 2015 revised curriculum for first and second graders of elementary school to cultivate safety awareness. This study aims to explore the relationship between concepts and concepts that are important in the Safe Life textbook using a keyword network analysis. The results indicate that the areas of life safety, traffic safety, and disaster safety are emphasized in terms of topics in the textbook. The teaching and learning methods for the Safe Life education are mainly based on "experience" and "practice," and the most common teaching materials are card games and sticky stickers. Based on the findings, we suggest maintaining the experience-oriented safety education approach and diversifying the teaching and learning materials and methods to incorporate various safety education areas.
