Purpose: The purpose of this study was to investigate perception of patient safety culture and safety care activity among hospital nurses and to identify factors associated with the safety care activity. Methods: A total of 399 nurses working at secondary or tertiary hospitals in B city were participated in. Data were collected using 'Questionnaire on Patient Safety' and 'Safety Care Activity Questionnaire'. Results: The mean score of patient safety culture was 3.41 out of possible 5. The mean score of safety care activity was 4.40 out of possible 5. There was a positive relation between the perception of patient safety culture and the safety care activity. Through stepwise regression analysis with 22.4% of accountability, it was found that the perception of the safety care activity was associated with communication process, a sub-domain of safety culture, marital status, experience of incidence reporting, and level of patient safety. Conclusion: The findings show the importance of communication among nurses to improve the safety care activity. To provide high quality of care for patients, it is necessary to educate nurses on fire safety, patient education, and medication safety and improve their communication skills.

Purpose: The purpose of this study was to investigate the effect of SBAR communication program on nurse's perception about communication and attitudes toward patient safety. Methods: A single-group pre-post experimental study was conducted. A SBAR education program was provided to 167 nurses working in 9 general wards of a hospital in Seoul. A total of 153 questionnaires were included for the final analysis. Statistical analysis included analysis of variance, paired sample t-test, and Cochran-Mantel-Haenzel test. Results: After applying SBAR communication education, nurses perceived significant improvement in three of the five categories of communication between nurses and doctors; satisfaction (p=.001), accuracy (p=.001), and understanding (p=.002). The indicators of communication between nurses were also improved significantly in the order of accuracy (p=.001), satisfaction (p=.001), shift communication (p=.001), and openness (p=.016). The scores of nurse's attitudes toward patient safety demonstrated a significant increase in the five categories out of the six; perception of management (p=.001), working condition (p=.001), safety climate (p=.001), teamwork climate (p=.001), job satisfaction (p=.012). Conclusion: It is recommended that nurses and doctors use SBAR communication in their practice. Developing education programs and utilization methods is required for the effective establishment of SBAR communication.

Safety-critical systems related to the railway communications are currently undergoing changes. Mechanical and electro-mechanical devices are being replaced by programmable electronics that are often controlled remotely via communication networks. Therefore designers and operators now not only have to contend with component failures and user errors, but also with the possibility that malicious entities are seeking to disrupt the services provided by theirs systems. Recognizing the safety-critical nature of the types of communications required in train control operations, the communications infrastructure will be required to meet a number of safety requirements such as system faults, user errors and the robustness in the presence of malicious attackers who are willing to take determined action to interfere in the correct operation of a system. In this paper, we proposed the safety strategies employed in the railway communications and a security mechanism for Korean railway communication system. Also, we presented the developed means for validation and determination of communication safety based on the proposed security mechanism in the railway system.

본 연구는 2012년 11월 2일 02시경 인천광역시 부평구 (주)이랜드월드 화재진압 도중 소방공무원 1명이 순직한 사고에 대해서 현장조사를 실시하여 현장진입대원과 현장안전 점검관 간에 안전여부를 확인하는 의사소통 수단인 무선통신(무전기)에 대한 문제점과 개선방안을 도출하였다. 연구결과 화재현장에서는 각종 소음이 심해서 대원과 현장안전 점검관 간에 육성으로는 의사소통이 곤란하고 무선통신에만 의존할 수 있음을 알 수 있었다. 따라서 인천소방안전본부에서 사용하고 있는 무전기와 주파수의 운용에 대해서 조사하였다. 또한 군과 경찰과도 비교해 보았다. 연구시험결과 인천소방안전본부에서 보유하고 있는 무전기와 주파수를 효과적으로 운용하면 현장안전점검관이 각종 재난현장에서 목숨을 걸고 화재나 인명구조 활동을 하는 대원의 안전여부 확인하는 의사소통을 원활히 할 수 있는 것으로 나타났다.

Nanotechnology is the fastest growing area in scientific research and it has important applications in a wide variety of fields. Nevertheless, consumers encountered this new technology without any identification of risks and benefits. Also until now, there are no specific safety evaluation methods for nanotechnology. For this reason, we studied risk communication strategy for nanotechnology to prepare its application in commercialized products on public. A survey was conducted to identify the differences in perception between public (N=110) and expert (N=37) toward applied nanotechnology in food, drugs and cosmetic products. The survey results were used to draw up a risk cognitive map which was introduced by Paul Slovic, and the perception level of public and expert on nanotechnology was evaluated. As a result of the survey, public recognized nanotechnology as "unknown but low dread" risk factor, but expert recognized it as "unknown and high dread" risk factor. These results indicate that there are perception differences between two groups. Several risk communication strategies are reported including care, consensus and risk communication. In the case of nanotechnology, it contains both risks and benefits. Considering the nature of nanotechnology, the "consensus communication" which informs consumers about risks and benefits of issues is the most appropriate strategy.

This paper reviewed the relationship between internal marketing(management support, education, pay system, internal communication, employment security) and food safety climate(prevention, superior attitude, work condition), and the moderating effect of employment type(permanent or temporary employees) in food service company. Based on the responses from 304 responses, the results of hierarchical multiple regression analysis showed that 4 factors(management support, education, internal communication, employment security) effect positively on food safety climate(prevention, superior attitude, work condition). The positive effect of internal communication on superior attitude and work condition appeared to be more positive in permanent employees than in temporary employees. And the results of t-test analysis showed that permanent employees perceived more positively all internal marketing factors(management support, education, pay system, internal communication, employment security) and food safety climate(precaution, superior attitude, work condition) than temporary employees.

The communication protocol for interface among railway signalling systems is designed and established as national standard in Korean from a few years ago. So the communication link for information transmission among railway signalling system can be a good example of application of this standard. Communication protocol which is standardized among Korean railway signalling is considered to apply information transmission. And we confirmed there is no the states of deadlock of livelock in std. protocol which is applied formal verification which is one of the analytic method for inspection of safety characteristics in the design course of protocol. But the safety of protocol has to necessarily accomplish this normal analysis approach about satisfying requirement matters with such this analytic approach. In this paper we analyzed the safety characteristics of standard protocol for Korean Railway signalling through the requirement matters for safety transmission of railway transmission system which is required in international standard. So through this study we confirm whether it satisfies safety requirement matters of the level which require in international standard and tried to confirm whether standard protocol has enough safety character in the real railway field.
