Purpose: The purpose of this study was to examine the impact of job satisfaction and organizational commitment on patient safety management activities of nurses. Methods: A cross-sectional design was adopted. The sample included 307 nurses working in three tertiary university hospitals. Data were collected during November and December, 2012, with a response rate of 93%. A 40-item patient safety management activities scale was used to measure patient safety activities. Job satisfaction and organizational commitment were also measured with established instruments and included general characteristics. Data were analyzed with PASW 18.0 program. Results: The mean score for patient safety management activities was 3.98 out of 5. Stepwise multiple linear regression indicated that organizational commitment (${\beta}$=.20, p<.001) and job satisfaction (${\beta}$=.18, p=.013) respectively predicted patient safety management activities. Especially, the addition of organizational commitment as the strongest predictor of patient safety management activities increased the associated explained variance ($R^2$ change=.11, p<.001). Conclusion: It is important for managers to create an organizational climate that promotes the organizational commitment and job satisfaction of nurses. Future studies are encouraged to replicate the findings and also to better understand patient safety management activities and personal emotional stability.

For the hydrogen economy system being tried starting with the 21st century, the fields that was not dealt with so far, such as the safety measure for large leakage accidents, the safety problem at infrastructures like a hydrogen station, the safety problem in terms of automobiles depending on introduction of hydrogen cars, the safety problem in a supply for homes like fuel cells, etc., are being deeply reviewed. In order to establish a safety control system, an essential prerequisite in using and commercializing hydrogen gas as an efficient energy source, it is necessary to conduct an analysis, such as analysis of hydrogen accident examples, clarification of physical mechanisms, qualitative and quantitative evaluation of safety, development of accident interception technologies, etc. This study prepared scenarios of hydrogen gas leakage that can happen at hydrogen stations, and predicted damage when hydrogen leaks by using PHAST for this.

Purpose: The purpose of this study was to analyze the concept of nurses' safety within the context of the hospital environment. Methods: We used Rodgers' method of evolutionary concept analysis and reviewed the relevant literature and noted and categorized characteristics that appeared frequently. Results: Nurses' safety was defined as safe status and safe activity among nurses. Three key defining attributes were identified as: (a) the minimization of actual or perceived risk, (b) personal duties and rights, and (c) ensuring within a safe working environment. Antecedents of nurses' safety were categorized into three dimensions: (a) individual, including vigilance and knowledge gained through education and training; (b) institutional, including safety provision in the organizations; and (c) national, including legislation. The outcomes of nurses' safety included the following: (a) continued competence in nurses' work; (b) enhancement of the quality of patient care; and (c) reductions in nurses' turnover rates. Conclusion: Nurses' safety ensures that qualified nurses are able to continue to perform their duties and provide good patient care. The findings of this study could contribute to future research examining nurses' safety. In addition, appropriate tools must be developed to measure the concept.

The purpose of this study is to develop and validate the disaster safety awareness scale for high school students. For this purpose, the previously developed disaster safety awareness scale and related prior research was analyzed. Questionnaire data was collected from March 22 to May 25, 2021 from 1054 students (male: 569, female: 485) in the first, second, and third grades of 5 high schools in 3 cities. Through the process of revising, supplementing, and reviewing the items extracted through preliminary research and preliminary test together with experts and students, a final disaster safety awareness scale consisting of 24 items was developed. This scale consists of four sub-factors: 'disaster prevention', 'disaster response A', 'disaster response B', and 'disaster recovery'. Good reliability and validity were secured through exploratory and confirmatory analyses. The significance of this study is that it laid a basic and objective foundation for high school students' disaster safety awareness research by developing a validated scale in a situation where the development of disaster safety awareness scales for high school students was still insufficient. It can be used as useful data for fire safety education as well as a psychological measurement tool for fostering fire safety awareness.

Workplace accidents are common while working at elevations. Thus, various safety measures such as safety handrails and horizontal safety nets are implemented to prevent falls. The minimum safety measure is the lifeline installation. However, because its standards have not been clearly established, it is often misused, resulting in inappropriate knot methods that increase the chance of accidents while working at elevations. Therefore, clarifying the appropriate usage methods or criteria for the various lifelines is required in the field. This study proposed an appropriate installation method by experimentally and numerically evaluating the change in strength according to the fixed knot lifeline method. In addition, three knot methods were specified for each material. The results obtained are expected to contribute to lessening falls through the establishment of lifeline installation standards and the development of appropriate parts.

The interaction and mixing of high-temperature melt and water is the important technical issue in the safety assessment of water-cooled reactors to achieve ultimate core coolability. For specific advanced light water reactor (ALWR) designs, deliberate mixing of the core-melt and water is being considered as a mitigative measure, to assure ex-vessel core coolability. The paper provides the background of past experiments as well as key fundamentals that are needed for melt-water interfacial transport phenomena, thus enabling the development of innovative safety technologies for advanced LWRs that will assure ex-vessel core coolability.

Computer aided unloading elastic compliance method was employed to measure the closure and the length of short cracks. The most significant factor that influences the fatigue growth behavior of short cracks is the crack closure Phenomenon. dc/dN-$\Delta$ $K_{eff}$ relationships of short cracks are found to coincide well with the corresponding long crack relationships. Non-propagating behavior of short cracks at notch root can be predicted from the crack opening SIF of short cracks, $K_{op}$ , and the growth equation of long cracks in Region I and II.n Region I and II.I.

The combustion instability of a rocket motor can be predicted by the linear stability analysis. The most important input data in this analysis is the combustion response function of the solid propellant. In many cases, it is very difficult to measure the function. But, in that case, the combustion response function can be theoretically evaluated by properties of the propellant. In this study, the theoretical values were compared with measured values by T-burner. Data are relatively so well agreed that theoretical values are enough to be used in linear stability analysis of the rocket motor using a newly developed propellant.
