Purpose: The purpose of this study was to investigate the influence of patient safety culture and perceived teamwork on the safety control of nurses. Methods: This study was conducted as a descriptive cross-sectional survey with 141 nurses who worked in a tertiary hospital with over 1,000 beds in S city, Gyeonggi province. Data were collected using structured questionnaires from July 20, to July, 31, 2015. Results: The average work period for nurses participating in the research was 8.84 years. The perceived teamwork and patient safety culture were positively correlated with safety control. The regression model with patient safety culture, perceived teamwork and clinical career against safety control was statistically significant (F=10.16, p<.001). This model also explained 37.1% of safety control (Adj. $R^2=.37$). Especially, communication (${\beta}=.27$, p=.023) of patient safety culture, clinical career (${\beta}=.26$, p<.001), mutual support (${\beta}=.24$, p=.042), and team leadership (${\beta}=.24$, p=.018) in perceived teamwork were identified as factors influencing safety control. Conclusion: The findings of this study imply that a broad approach including teamwork and patient safety culture should be considered to improve the safety control for nurses.

This paper deals with an efficient and effective method on measuring, monitoring and evaluating safety and environmental performances of a process using SPC control charts. We propose 7 safety control charts as a tool to monitor hazard dendritics, and we propose 15 environment control charts to monitor pollution emissions. We also propose useful guidelines that SPC(Statistical Process Control) control charts can be used for safely and environmental monitoring.

The purposes of this study are to analyze the realities after enforcements of safety control regulations for diagnostic X-ray equipments and to suggest means for an improvement of low radiation safety control. A questionnaire survey for medical radiologic technologists was carried out to determine enforcement effects of the safety control regulations. The results of analysis from the survey are as follows. That is, most of the respondents realized the importance of the radiation safety control system, but about a half of them revealed that the regulations were not well observed in accordance with their purposes. Only 43.9% of the respondents took an active part in quality control and safety control of radiation. And respondents responsibility, sex, age, and knowledge for safety control were important indicators for observations of the regulations. Trainings for the safety control regulations are needed to ensure safety control and proper usage of diagnostic X-ray equipments. And management of organizations using diagnostic X-ray equipments have to understand and stress the importance of radiation safety control system.

In this study, the effect of damping and elastic nature on the control performance of a safety budget-industrial accident rate model in Korea is examined first. The effectiveness of such dynamic model in establishing safety policies is shown with a simple proportional-integral(PI) feedback control mechanism. Control performance of the safety system model is explained in view of maximizing the effect of IAPF and minimizing the absolute amount of IAFP. Control performance is then evaluated and proved to be effective to prevent and reduce the industrial accidents. Implications in feedback control of a safety system model suggested to optimization of safety policies are also explored. Without proper restructuring of the safety system, it would not be possible to hit the target industrial accident rate. Even if the control objective is met, the amount of industrial accident prevention fund required to reduce the industrial accident rate from the current level to the target level would be far beyond the social consensus.

Despite the government's various safety measures, the number of safety accidents continues to rise and the interior is more likely to occur indoors than outdoors. Safety accidents involving young children account for more than 70 % of the safety accidents in the safety accidents, and the ratio of safety accidents in the classroom or classroom is more than 50 %. In this thesis the author proposes the system managing the accidents notification service using LED lighting and access entry control. Utilizing IoT technology, remote control or access can be controlled remotely by controlling multiple lights and entrances from each room and by means of a number of lighting and entrances. By monitoring and analyzing real-time status via server PC and mobile interface, it can control the maximum control and incident prevention, automatic control, and automatic control.

The safety of the railway system is important because the system is a mass transit system and the results of the accident are inconceivable. The railway system is operated by train operation system such as train control system. So the train control system requires safety critical characteristics. In the European railway, ETCS (European Train Control System) project has been finished to accomplish the interoperability of each national railway signaling system. According to the interoperability degree, ETCS levels are suggested. As the highest level, ETCS level 3 suggests a radio communication. Also recently urban railway system is operated by driverless and automatic train control system. In this circumstance, more safety is required than before in the railway system. In order to accomplish the safety of a system, the requirements considering safety have to be suggested. The requirement is a set of several functions such as general function, environment, safety etc. For the safety critical system, safety function is more important than any other functions. The safety functions are deduced by safety analysis. In order to perform the safety analysis, the system hazards have to be identified and then risk analysis for each hazard should be performed. The risk is related to the frequency and the severity of each hazard. And then countermeasures for each risk have to be prepared. The summary of the countermeasures is about a kind of safety functions in a system. In this paper, the safety functions for a train control system are presented according to the above procedure.

This study investigated the effect of situation-oriented safety education program on children's safety knowledge and safety problem-solving skill. Subjects were 51 five-year-olds(25 in the experimental group and 26 in the control group) who were enrolled in public kindergarten located in Jeon-Buk. Results were that : First, there were significant differences in the children's safety knowledge between the experimental and the control group. Children's safety knowledge in the experimental group were improved in comparison with those of the control group. Second, there were significant differences in the children's safety problem-solving skill between the experimental and the control group. Children's safety problem-solving skill in the experimental group were improved in comparison with those of the control group.

This study focuses on the issue of control performance of safety budget for preventing and reducing industrial accidents in Korea. The effect of safety budget such as industrial accident prevention fund on the safety performance is statistically examined first. The role and control performance of industrial accident prevention fund is particularly addressed to reduce the related accidents. The effectiveness of the industrial accident prevention fund-industrial accident relationship is then explained with a simple PI control mechanism.
