This study was conducted with the following three study objectives. First, effects of safety awareness level of lab researchers to the improvement of safety culture in the organization Second, effects of organizational safety behaviors to the improvement of safety culture Third, test of mediating effects of organizational safety behaviors in the relationship between safety awareness level and the improvement of safety culture. The results show that organizational safety behavior is an indispensable factor for the improvement level of safety culture. Especially, the factors in safety training activities, safety compliance and management system are mediating variables which affect the safety awareness level and improvement level of safety culture, which shows these variables are very important factors in reducing safety accidents through the improvement of safety culture. Therefore, safety behaviors in the organization should be considered with priority. If the organization leads to improve safety awareness through regular safety training and rewards and punishes according to the test results, safety awareness could be improved. This study was conducted to identify the necessary factors to improve the overall safety culture in the organization and contribute to the diffusion of safety culture by improving the safety training awareness of the researchers.

Today's manufacturers must respond quickly to customer needs. In particular, make-to-order companies are constantly striving to satisfy customer demand for products in order to secure more favorable conditions in the future through bidding. In this bidding process, quotations play a very important role in providing favorable conditions. And the most important content that companies strive to satisfy their customers is the product's performance. Therefore, a company can attract customers and secure economic profits through good quotations, but it can be said that the first priority is to match the performance of the products requested by the customers. That is, when a company creates a quotation, it is important to structure the quotation according to the performance of the product. Thus, this paper intends to present a quotation management framework and a quotation BOM information model for constructing quotations efficiently in make-to-order manufacturing. And, in order to prove the usefulness of the proposed quotation management framework, we presents an case of the construction of an quotation management system based on the JAVA platform. As a result, the integrated quotation management system based on the proposed quotation management framework and quotation BOM has been successfully operated in a make-to-order company that manufactures marine engines.

In an effort to decrease aviation accident worldwide, development of aviation safety management has been sought through aviation index and standardization, both by establishing SMS(Safety Management System). It also needs to be done in the domestic. both study on SMS which ICAO recommends and setting the top priority safety goal, each differently classified by nations. Accordingly, defining safety index and developing continuous monitoring approach. Aircraft accident reporting system in Air Force does not operate in a open approach method due to its uniqueness related to mission achievement. Therefore, limits of utilizing the recent worldwide aircraft data sharing and analyzing results to prevent accident is inevitable. This paper introduces an overview of ECCAIRS 5 which become the standard for the recent worldwide aviation safety reporting and data exchange system. Also using ECCAIRS 5, aircraft accident cases of the Air Force are classified such as accident type, year, month, occurrence category, and flight phase. The result of the study will provide a guide line for utilizing the civil system in prevention of future military aviation accidents.

The relationship between near misses and major accidents can be confirmed using the ratios proposed by Heinrich and Bird. Systematic reviews of previous national and international studies did not reveal the assessment process used in near-miss management systems. In this study, a model was developed for assessing near misses and major factors were derived through case application. By reviewing national and international literature, 14 factors were selected for each dimension of the P2T (people, procedure, technology) model. To identify the causal relationship between accidents and these factors, a near-miss assessment model was developed using a Bayesian network. In addition, a sensitivity analysis was conducted to derive the major factors. To verify the validity of the model, near-miss data obtained from the ethylene production process were applied. As a result, "PE2 (education)," "PR1 (procedure)," and "TE1 (equipment and facility not installed)" were derived as the major factors causing near misses in this process. If actual workplace data are applied to the near-miss assessment model developed in this study, results that are unique to the workplace can be confirmed. In addition, scientific safety management is possible only when priority is given through sensitivity analysis.

Purpose: The purpose of this study is to suggest a modified approach that compensates some shortcomings of RPN with relevant strength of ASIL for Safety System and suggests systematic and logical approach for FMEA. Methods: By comparing the objectives, determination procedures, and key conceptual differences of RPN and ASIL, a refined method of risk evaluation and a new risk metric are devised. Results: While the traditional FMEA provides only rough evaluation of relative risk for each failure, the proposed method compensates its shortcomings with relevant strength of ASIL and provides a more logical and practical procedure of risk evaluation. Conclusion: The new metric RPM provides not only a comparative priority rank but also the degree of physical seriousness. Besides, it may have even more benefits for various applications if the severity can be expressed as mone tary amount of losses.

Purpose: This study was to investigate the relationships among patient safety culture, safety competence and safety nursing activity among nurses in anesthetic and recovery rooms, and to identify the factors contributing to safety nursing activity. Methods: A descriptive correlational study was conducted. Participants were 156 nurses from 13 hospitals. Data were collected from February 11 to March 15th, 2019, and analyzed using descriptive statistics, t-test, Mann-Whitney U test, one-way ANOVA, Pearson's correlation and multiple regression analysis with SPSS statistics 24.0 Program. Results: Safety nursing activity was significantly different in relation to nurses' level of education, position at work, clinical career, clinical career at anesthetic and recovery rooms, and work experience in patient safety. Safety nursing activity demonstrated a significant positive correlation with patient safety culture and patient safety competence. Factors contributing to safety nursing activity were patient safety knowledge, skill and attitude, clinical career, clinical career at anesthetic and recovery rooms, and the patient safety improvement system which explained 57.0% of total variance of safety nursing activity. Conclusion: To improve safety nursing activities at anesthetic and recovery rooms, it is necessary to develop patient safety programs with enhanced knowledge, skill and attitude to take patient safety as a top priority.

Background: The relationship between risk factors and likelihood of occupational injury has been studied. However, what has been published has only provided a limited explanation of why some of the employees working in the same environment as other employees suffered a single-injury event, while other employees experienced multiple-injury events. This article reports on an investigation of whether artisanal and small-scale miners in Migori County of Kenya are susceptible to a single-injury or multiple-injury incidences, and if so, what underpinning parameters explain the differences between the single incident injured and the multiple incident injured group. Mine management commitment to safety in artisanal and small-scale mining (ASM) operations is also considered. Materials and methods: The research objectives were achieved by surveying 162 uninjured and 74 injured miners. A structured, closed-end questionnaire was administered to participants after the stratification of the study population and systematic selection of the representative samples. Results: The results showed that most injured miners suffer a single-injury incident rather than experiencing multiple-injury events, and laceration (28.40%) was the common injury suffered by the miners. The analysis showed that the risk factors for the single incident injured group were not similar to those in the multiple incident injured group. The research also found mine workers have low opinion about mine management/owners commitment to safety. Conclusion: The study concluded that mine management and miners need to be educated and sensitized on the dangers of this operation. Provision of safety gears and positive safety culture must be a top priority for management.

Objectives: This study was performed in order to establish reliable and relative selection criteria for hazardous substances requiring management(HSRM) in the Occupational Safety and Health Act in Korea. Methods: To determine the relative criteria and weight of evidence for HSRM, we analyzed the difference between the selection method of priority substances in studies by KOSHA(Korea Occupational Safety and Health Agency) and the European Union Risk Ranking Method(EURAM). In addition, 597 hazardous substances with exposure limit valueswereanalyzed and the posted health hazards classification by MOEL(Ministry of Employee and Labor), MOE(Ministry of Environment), and EU CLP(Classification, Labelling and Packaging regulation) were compared based on GHS(Globally Harmonized System of classification and labelling of chemicals) criteria. The existing HSRM(167 substances) were evaluated for suitability by the proposed criteria in this study. Results: As a result of this study, the criteria and procedures for selecting HSRM in the Occupational Safety and Health Act were arranged utilizing GHS health hazard classification results, occupational disease cases and domestic use situations. Conclusions: The applicability of the proposed criteria was proved via the evaluation of existing HSRM(167 substances). Most HSRM (161 substances) were found to correspond to a significant health effect or substantial health effect. The question of whether to include the six substances that have been found to have general health effects as HSRM would be require further research.
