This study is intended to estimate influences upon life cycle of ESPE(Electro Sensitive Protective Equipment) which is kinds of commonly used in press in domestic industry. First the field survey is executed to workers and safety managers at work places. In the survey, the main primary factors influenced the lift cycle of ESPE were vibration due to overload work in workplace. Second, int results showed that 37$m/s^2$ acceleration in press work would lead to the life of 132 for 8 hours work per day. Therefore, the vibration of press inflicted significant effect on the lift of ESPE.

This study is a study to estimate the VSL (Value of a Statistical Life) and CBA (Cost-benefit analysis) of the rollover safety standard for hydrogen buses, VSL is an economic value concept used to quantify the benefits of avoiding death. CBA shows the effect of cost-benefit, and if B/C is greater than 1, there is a social effect. In order to estimate the VSL and CBA, the hydrogen bus introduction scenario was assumed to be optimistic (20,000 vehicles in 2030), neutral (15,000 vehicles in 2030), and pessimistic (10,000 vehicles in 2030), and the effect of reducing human casualties was estimated. As a result, except for the pessimistic market situation of introducing hydrogen buses (10,000 vehicles in 2030) and the VSL reduction ratio of 10%, all policies were judged to have high cost-benefit effects. These results indicate that the introduction of the rollover safety standard for hydrogen buses is a socially effective policy.

IoT-based services are being released in accordance with the aging population and the demand for well-being pursuit needs. In addition to medical device companies, companies with ideas ranging from global ICT companies to startup companies are accelerating their market entry. The areas where these services are most commonly applied are health/medical, life/safety, city/energy, automotive and transportation. Furthermore, by expanding IoT technology convergence into the area of life care services, it contributes greatly to the development of service models in the public sector. It also provides an important opportunity for IoT-related companies to open up new markets. By addressing the problems of life care services that are still insufficient. We are providing opportunities to pursue the common interests of both users and workers and improve the quality of life. In order to establish IoT-based digital life care services, it is necessary to develop convergence technologies using cloud computing systems, big data analytics, medical information, and smart healthcare infrastructure.

This paper surveys and researches primary school students' situation of their school life. The purpose of this paper is to propose the basic information of the accident prevention teaching and the safety management in order to avoid accidents to occur beforehand. We selected m primary students out of the six primary schools in Taebaek City at which the nursing students of Kangwon Tourism College practiced school health. We used SPSS Win for analyzing data. We carne up with the general characteristics and percentage using frequency analysis, mean and standard deviation of each item, the mean difference using T-Test, and the different factors using one-way analysis. The results are as follows: 1. The 6th grade students don't practice safety procedures than the 5th grade students during outside the school. The older the student is, the less it practices safety procedures. 2. Boys practice safety procedures better than the girls during inside and outside the school. 3. Hot -tempered students don't practice safety procedures properly. 4. Most of the students who often use the health room of the school have high scores in safety procedures test and as a result, these students practice safety procedures thoroughly. 5. The grade of safety living activity is the highest during gymnastic class. Next is when the students use the stairs when they are going up and clown. Then, the use of science room In the playground is the lowest grade of safety for living activity.

Purpose: The purpose of this study was to provide basic data to develop safety education programs in elementary school. Method: Analysis is made based on textbooks for $1st-{\sim}6th-grade$ elementary school students published by Korea Ministry of Education & Human Resources Development. Results: 1) Among the textbooks. only , . , and courses dealt with safety education. 2) The contents of safety education included traffic safety, water safety, indoor and outdoor safety, fire, emergency measures, misuse and abuse of drug, smoking, toy safety, sports safety, leasure safety and disasters. However, the contents were theoretical, fragmentary, local and limited. Conclusion: These results suggest that the consents of safety education must be strengthened, and more practical and more behavior-oriented in consideration of activities.

This study is intended to provide legislative direction for fire products life expectancy. Domestic and international laws relating to fire products life expectancy have been reviewed, and the results of a Fire Safety Manager Consciousness (FSMC) survey were analyzed. The FSMC survey has been designed in order to assist with the establishment of appropriate fire safety policy. A questionnaire survey was conducted with 660 fire safety administrators from 17 municipal and provincial districts, with the intention of gaining expertise on the extension of life-span for 32 fire products. The survey also asked for candidates opinions on future policy direction. Based on the survey results and the review of policies within other nations, we have devised a set of policy issues with the intention of extending the life-span of fire-safety items. The survey result revealed that 79.3% of Fire Safety Managers (FSMs) concurred with the establishment of legislation regarding the maintenance and correct care of fire-safety products. Overall, over 30% of FSMs were in favor of regulations regarding Ddry chemical fire extinguishers (77.3%), fire detectors (44.6%), fire hoses (44.4%), gaseous agent fire extinguisher (40.6%), automatic descending life lines (36.2%), exit lights (35.9%), air respirators (35.9%), extinguishing systems for residential cooking facilities (33.9%), automatic spray-type extinguishing units (33.9%), emergency lights (31.2%), and gas leakage detectors (30.7%). Especially, among these, dry chemical fire extinguishers (60.0%), detectors (20.0%), and fire hose (18.8%) were identified as the fire products primarily in need of maintenance legislation. The general consensus is that fire products older than 10 years need to be replaced. Based on the survey results, there was general agreement that fire product life expectancy is in need of legislation. This study recommends the introduction of fire product life expectancy legislation in phases.

In this study, to recognize the limitations and problems of fire safety in existing deteriorated buildings in Korea, and to analyze the fire case of Jongno Gooshiwon, the fire life safety assessment was performed and analyzed through fire egress simulation and analyzed the domestic and foreign related codes and regulations. In order to secure the fire safety of existing deteriorated buildings, it is necessary to adopt the systematic introduction and application of fire safety performance evaluation of buildings based on quantitative and objective indicated method for performance maintenance and management for fire life safety.
