As the first step of risk management, risk identification is inevitable to understand the degree of work safety. However, the safety requirements can be divided in necessary factors and additional factors. Thus, we propose a safety requirements assessment model using Kano model derived from Herzberg's two-factor theory, classifying safety requirements into ideal elements and must-be elements. The Kano model is usually applied to evaluate customer satisfaction divided into three major requirements in the fields of product development and marketing: attractive, must-be, and one-dimensional requirements. Among them, attractive requirement and must-be requirement are matched with ideal element and must-be element for safety requirement classification, respectively. The ideal element is defined as preventive safety elements to make systems more safe and the must-be element is referred to as fatal elements to be essentially eliminated in systems. Also, coefficients of safety measurement and safety prevention are developed to classify different class of safety requirements. The positioning map is finally visualized in terms of both coefficients to compare the different features. Consequently, the proposed model enables safety managers to make a decision between safety measurement and prevention.

Purpose: The purpose of this study was to measure the effects of a school safety education program based on the PRECEDE-PROCEED model for upper grade elementary students. Methods: One hundred ten 6th-grade students sampled from an elementary school in D City were divided into the education group (n=55) and the non-education group (n=55). School safety education was provided to the education group for 8 weeks and a questionnaire survey about safety knowledge, safety practice and the frequency of safety negligence was carried out before and after the education from March 2 to July 13, 2010. Results: After the application of the safety education program, the education group got a higher safety knowledge score than the non-education group (p<.001). Both the education and non-education groups showed a significantly increased safety practice score (p<.01). In the comparison of safety negligence, the education group showed lower frequency (p<.01). In addition, according to the results of ANCOVA and t-test, the school safety education program influenced safety knowledge significantly (p<.001). Conclusion: This result shows that a school safety education program based on PRECEDE- PROCEED can improve safety knowledge. Further studies will be required to develop continuous and systematic safety education programs.

Purpose: This study was performed to measure hospital nurses' perceived patient safety culture and their safety care activities, and to investigate the relationship between these two factors. Method: This study was a cross-sectional survey. The participants were 301 nurses working at 4 general hospitals, and data collection was done from June 22 to June 30, 2009 by self-administrated questionnaires. Results: With a possible score of 5 points, the average score for nurses' perceived patient safety culture was 3.34, and for their safety care activities, 4.25. There were perceived differences in patient safety culture and safety care activities according to age, position, length of work experience and number of patient safety education sessions attended. All sub-factors in patient safety culture had a positive relationship with safety care activities. Factors influencing nurses' safety care activities were number of patient safety education sessions attended, hospital environment, and supervisor/manager. These factors explained 58.2% of the variance. Conclusion: The findings indicate that patient safety education is very important to improve nurses' safety care activity. So nursing supervisors/ managers should develop strategies encourage patient safety education, and make nurses' working environment safer.

Background: This study aimed to prioritize policy measures to improve radiation safety management in medical institutions using the analytic hierarchy process. Materials and Methods: It adopted three policy options-engineering, education, and enforcement-to categorize safety management measures, the so-called Harvey's 3Es. Then, the radiation safety management measures obtained from the current system and other studies were organized into action plan categories. Using the derived model, this study surveyed 33 stakeholders of radiation safety management in medical institutions and analyzed the importance of each measure. Results and Discussion: As a result, these stakeholders generally identified enforcement as the most important factor for improving the safety management system. The study also found that radiation safety officers and medical physicists perceived different measures as important, indicating clear differences in opinions among stakeholders, especially in improving quality assurance in radiation therapy. Hence, the process of coordination and consensus is likely to be critical in improving the radiation safety management system. Conclusion: Stakeholders in the medical field consider enforcement as the most critical factor in improving their safety management systems. Specifically, the most crucial among the six specific action plans was the "reinforcement of the organization and workforce for safety management," with a relative importance of 25.7%.

Work Guideline of Construction Quality Management was revised in July 2017, and it has changed the perception of scaffolding in South Korea. The on site investigation and survey was performed on manufacturers, leasing companies, and quality inspection agencies regarding the compliance with the guideline for the scaffolding and the related components brought to the site. Moreover, the related guidelines and identified unsatisfactory quality management items were analyzed by each subject. As a result, the major factors that cause the problems were reasonably deducted. The related regulations to prohibit the delivery of faulty scaffolding components to the construction site in order to secure the safety of the temporary structure was suggested.

Normal Operation Safety Survey (NOSS) is a safety management tool used by air traffic control organizations to measure data related to threats and errors to proactively prevent accidents before they occur. NOSS was developed to be applied to the air traffic control field according to the concept of Line Operation Safety Audit (LOSA) conducted by airlines to reduce human errors in the cockpits. Safety management based on data is crucial for the prevention of control-related accidents, and the competency of observers for this is important for the successful implementation of NOSS. Based on LOSA implementation experiences and expert interviews, this paper introduces the international NOSS methods and discusses the key factors required for effective observation and the implementation methods and implications of NOSS observer training.

In Korea, the occurrence and risk of similar fires are high, so setting up fire prevention measures through fire case investigation is considered the most basic measure in securing human safety. In particular, calculation of evacuation capacity in evacuation safety design of buildings is the most important factor that directly affects evacuation safety performance. However domestic standards is not consider about occupant characteristics. also the case of domestic, it has the problem that the law is partially applied when the fire safety design of buildings. Therefore, the purpose of this study is to study the current status and related regulations of the life safety code for the application of high fire risk buildings, and to analyze the difference in evacuation time through Case Study.

Data released by the National Fire Agency showed that the total incidence of fires from 2014 to 2023 was 410,497, among which 75,215 were house fires, constituting 18% of the total occurrences. The fatalities resulting from house fires numbered 1,435. Fatalities stemming from prior house fires occurred between midnight and 6 am, coinciding with periods of sleep and diminished responsiveness to fire emergencies. A fire safety labeling system is proposed to prevent fire hazards associated with household products. This system primarily entails indicators of thermal energy and inherent fire attributed to household products. Furthermore, the Korea Fire Safety Institute has suggested adopting a risk label as a concrete measure plan for implementing the fire safety labeling system for household products. The results promise to safeguard the public against fires and increase the exports of household commodities by enhancing the corporate reputation through positive association with fire safety measures.

In this paper, a reliability-based design optimization is developed for the topology design of linear structures using a performance measure approach. Spatial domain is discretized using three dimensional Reissner-Mindlin plate elements and design variable is taken as the material property of each element. A continuum based adjoint variable method is employed for the efficient computation of sensitivity with respect to the design and random variables. The performance measure approach of RBDO is employed to evaluate the probabilistic constraints. The topology optimizationproblem is formulated to have probabilistic displacement constraints. The uncertainties such as material property and external loads are considered. Numerical examples show that the developed topology optimization method could effectively yield a reliable design, comparing with the other methods such as deterministic, safety factor, and worst case approaches.

Especially because of the distinctiveness that new experiments and research provoke coexistence of various risk factors, the researchers in university laboratory are being exposed to incidents that are difficult to predict. Due to the fact that the numbers of accidents that occur at the university laboratory are increasing, the necessity for laboratory safety management is on the rise. Most laboratory accidents are caused by the ability that can detect risk factors such as unsafe behavior or unsafe condition but is not working perfectly. In order to prevent researchers in advance from unsafe behavior or unsafe condition, effective safety education, systematic safety management, safe research environment, continuous safety check and proper measures after accident are the most important factors. In this study, survey was conducted in university laboratory to identify the factors that affect on safety management and to measure the safety management level. As a result, effective measures are proposed for the improvement of the safety management level.
