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.

Currently, safety management is becoming important at domestic construction sites. Despite the importance of safety management, accidents at construction sites are steadily increasing. Fire accidents among safety accidents cause not only negative effects on schedule delay or work plans at construction sites, but also huge casualties. Therefore, the purpose of this research is to extract the causes of fire at the construction site through the case of fire at the construction site, and to prioritize prevention through the analysis of the factors to contribute to the prevention of fire. As a research method, we select fire factors through case, conduct surveys through expert group, and analyze survey through AHP technique. The results of the AHP analysis of the survey of expert groups showed that the workers and their sub-item ranked high. Therefore, the priority for fire prevention was given, and this research is believed to help prevent fire.

This paper is analyzed for the thermal characteristics(1 year) of the 6 components(DC breaker, DC filter(including capacitor and discharge resistance), IGBT(Insulated gate bipolar mode transistor), AC filter, AC breaker, etc.) of a photovoltaic power generation-based PCS(Power conditioning system) below 20 kW. Among the modules, the discharge resistance included in the DC filter indicated the highest heat at $125^{\circ}C$, and such heat resulting from the discharge resistance had an influence on the IGBT installed on the rear side the board. Therefore, risk priority through risk priority number(RPN) of FMEA(Failure modes and effects analysis) sheet is conducted for classification into top 10 %. According to thermal characteristics and FMEA, it is necessary to pay attention to not only the in-house defects found in the IGBT, but also the conductive heat caused by the discharge resistance. Since it is possible that animal, dust and others can be accumulated within the PCS, it is possible that the heat resulting from the discharge resistance may cause fire. Accordingly, there are two options that can be used: installing a heat sink while designing the discharge resistance, and designing the discharge resistance in a structure capable of avoiding heat conduction through setting a separation distance between discharge resistance and IGBT. This data can be used as the data for conducting a comparative analysis of abnormal signals in the process of developing a safety device for solar electricity-based photovoltaic power generation systems, as the data for examining the fire accidents caused by each module, and as the field data for setting component management priorities.

After forming a institutional framework with specified in Maritime Safety Law(ex. Maritime Traffic Safety Law) on May 27th, 2009, The efforts for improving 'Maritime Traffic Safety Assessment Scheme(MTSA scheme)' have continued to the present. But there's no review with the comprehensive and systematic approach for proceeding acceleration step of MTSA scheme. At this point, this study analyzed current status and derived improvement measures using by 'PIP'OU model' which was designed for the comprehensive analysis in accordance with metaevaluation theory, like as question investigation and etc. Consequently, it mainly needs to improve 'Assessment Plan' domain and minimized the difference in views between concerned parties. This study is expected to be used to develop systematic maritime policy by proposing the order of priority in improvement matters.

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%.

In recent years, the natural damage associated with flood disaster has been dramatically increased. However, there is no rational method which reflects urban characteristics to estimate the regional safety assessment for flood disaster. The purpose of this study is to develop the regional safety assesment model for urban flood. Flood risk and reduction assesment were estimated by using the linear sum of the Z score of the assessment factors and the weight value of each factor from the expert survey data. And then the regional safety assessment was estimated by subtracting reduction factor value from risk factor value. GIS tool was used to estimate the factor assesment and integrated regional safety. This study can be used to determine the priority of flood protection project, execute the flood insurance and establish the urban plans and the flood mitigate plan.

We establish an expert system for the xylene oxidation reaction process of chemical plants using HAZOP(Hazard and Operability Studies). Our research focus Is only reduced to the cooling system of the total chemical plant due to lack of information. This expert system shows the priority of reasons for the system failure using confidence factor.

In Factory, as the number of machine is increased the more maintenance efforts are necessary. Multi maintenance issues may occur at a certain time and the determination of maintenance sequence is needed. In this study, we first compare the priority of machines and the impact value using modified FMEA(Failure Mode Effect and Analysis) method. Also, CBR(Case-based Reasoning) approach is applied to retrieve similar fault cases of current machine problem. The proposed methodology will be useful to implement decision support system of maintenance sequence for CMMS/EAM (Computerized Maintenance Management System/Enterprise Asset Management).

This paper deals with the selection of a proper dispatching rule for an one-process Job scheduling that follows a particular distribution of an order production. That is, it makes a distribution on an order per unit period and applies to simulation model that uses it. This study consists of two purposes either seeks adequately production scheduling using priority rule or seeks extension of the facilities that increase current production efficiency through computer simulation in scheduling.
