Purpose: The purpose of this study was to identify the factors related to blood-borne infection prevention behaviors based on the risk perception of the health belief model among operating room nurses. Risk perception factors included perceived susceptibility, barriers, benefits, and perceived severity. Methods: Data were collected from 121 operating room nurses working in four different hospitals in Daejeon and Seoul from June 30 to May 11, 2016. Results: The mean age was 31.2 years, and the average years of clinical experience in operating room was 7.9 years. The mean score of knowledge was 13.15. The mean score of perceived susceptibility, barrier, benefit, and perceived severity were 3.76, 3.70, 3.95, and 4.64, respectively. Blood-borne infection prevention behaviors had positive correlation with perceived benefits (p=.010), but negative correlation with sensitivity (p=.009) and barrier (p=.012). The hierarchical regression model on infection prevention behavior was statistically significant (F=4.85, p<.001). The sixteen percent of variance in behavior was explained by age (${\beta}=.18$, p=.038), perceived benefit (${\beta}=.20$, p=.030), perceived susceptibility (${\beta}=-.25$, p=.005), and perceived barrier (${\beta}=-.18$, p=.042). Conclusion: In order to increase infection prevention behaviors among operating room nurses, there is a need for developing specific education program focusing on appropriate management of equipment, instruments, and environment in operating room. In addition, support from the hospital organization level need to be provided as well.

Purpose: This study was to compare the predictive validity of Norton Scale(1962), Cubbin & Jackson Scale(1991), and Song & Choi Scale(1991). Method: Data were collected three times per week from 48~72hours after admission based on the four pressure sore risk assessment scales and a skin assessment tool for pressure sore on 112 intensive care unit(ICU) patients in a educational hospital Ulsan during Dec, 11, 2000 to Feb, 10, 2001. Four indices of validity and area under the curve(AUC) of receiver operating characteristic(ROC) were calculated. Result: Based on the cut off point presented by the developer, sensitivity, specificity, positive predictive value, negative predictive value were as follows : Norton Scale : 97%, 18%, 35%, 93% respectively; Cubbin & Jackson Scale : 89%, 61%, 51%, 92%, respectively; and Song & Choi Scale : 100%, 18%, 36%, 100% respectively. Area under the curves(AUC) of receiver operating characteristic(ROC) were Norton Scale .737, Cubbin & Jackson Scale .826, Song & Choi Scale .683. Conclusion: The Cubbin & Jackson Scale was found to be the most valid pressure sore risk assessment tool. Further studies on patients with chronic conditions may be helpful to validate this finding.

Background: Korea's health screening program has been faced the need for changes as the population and diseases structure are changing. In addition to Korea, many countries operate state-led health check-up programs to improve the health level of the people, and the operating methods of the program appear in various forms according to each country's health insurance system. This study examines other state-led health screening programs and proposes a direction for the development of Korea's health screening program. Methods: The study was conducted using the literature review method, and the "country" was set as a unit for the case analysis. The operating method of the health screening programs and the financial resources were compared according to the health insurance system. Five countries were selected as Korea, the United States, the United Kingdom, Japan, and Taiwan. Results: The analyzed countries mainly operate the health screening program as a management method for chronic diseases, but there were differences in the operating method, financing, and targeted subjects and examination items. In most countries, a risk assessment was performed prior to the examination (screening), and the subjects who needed the examination were first selected, and a follow-up management service was provided in accordance with the risk each individual exposed. Conclusion: Rather than applying the same screening method to populations with different risk levels, a health screening program will be constructed in consideration of the individual's health level and exposure risk, and the healthcare delivery system will be reorganized so that screening and treatment services can be linked.

Risk assessment system which is the point of occupational safety and health management system is recognized to be effective to prevent industrial accident and occupational disease internationally. Ministry of Employment and Labor developed guidance on risk assessment at workplace recently. This guidance presents standard model on risk assessment at workplace. However, enterprises may be confronted with many questions in the process of introducing and operating risk assessment. For risk assessment to be implemented properly and effectively at workplace, there are various questions that need to be considered in advance, including giving shape to standard on risk evaluation and clarifying the implementation system at workplace in advance. Also for risk assessment to be revitalized at workplace, several policy matters need to be settled. First, an administrative agency should present the implementation method of risk assessment more concretely. Secondly, it is necessary for an administrative agency to develop and spread various detailed manual, models and good practices related to risk assessment. Thirdly, a government agency need to apply an incentive & disadvantage policy actively to risk assessment.

All activities relate to railway traffic involve risk and that these arise from a combination of the nature of operating activities. Proper management system is required to provide the organizational capability to reveal, analyse and address these weaknesses over time and in reasonably practicable ways, which will determine the rate at which risks can be further reduced. This paper presents a systematic risk analysis approach to safety planning and decision making, informed by a range of risk assessment techniques. An railway organization's safety management system is also presented that shows the approaches taken to minimize the external risks, and identify the shared risks and explain how they will be controlled through collaboration with others.

PURPOSES : The objective of this study is to establish the traffic volume-based warrants of right-turn lanes at unsignalized intersections and to introduce a risk probability methodology based on the warrants. METHODS : In this study, a risk probability of a potential rear-end collision is applied between a right-turn vehicle and the immediately following through vehicle. Using the shifted negative exponential model and the compound probability theorem, the risk probability can be expressed as the function of directional volumes and the percentage of right-turns for a two-lane and four-lane highway, respectively. RESULTS : Based on the risk probablity, guidelines for installing right-turn lanes on two-lane and four-lane highways were developed. The risk probability also showed rationality by comparing with right-turn same-direction conflicts observed in-situ. CONCLUSIONS : The results of our study define the total approaching volumes to encourage a right-turn lane as a function of operating speed, percentage of right-turn, and number of lanes.

Background: The Berg Balance Scale (BBS) and the Fullerton Advanced Balance (FAB) scale have been used to assess balance function in patients with chronic stroke. These clinical balance scales provide information about potential risk factors for falls. Objects: The purpose of this study was to investigate the incidence of and risk factors of falls and compare the predictive values of the BBS and FAB scale relative to fall risk in patients with stroke through receiver operating characteristic analysis. Methods: Sixty-three patients with stroke (faller=34, non-faller=29) who could walk independently for 10 meters participated in this study. The BBS and FAB scale were administered. Then, we verified the cut-off score, sensitivity, specificity, and the area of under the curve. Results: In this study, the BBS and FAB scale did not predict fall risk in patients with stroke in the receiver operator characteristic curve analysis. A cut-off score of 37.5 points provided sensitivity of .47 and specificity of .35 on the BBS, and a cut-off score of 20.5 points provided sensitivity of .44 and specificity of .45 on the FAB scale. Conclusion: The BBS and FAB scale were not useful screening tools for predicting fall risk in patients with stroke in this study, but those who scored 37.5 or lower on the BBS and 20.5 or lower on the FAB scale had a high risk for falls.

Purpose: Emergency operations for perforated peptic ulcer are associated with a high incidence of postoperative complications. While several studies have investigated the impact of perioperative risk factors and underlying diseases on the postoperative morbidity after abdominal surgery, only a few have analyzed their role in perforated peptic ulcer disease. The purpose of this study was to determine any possible associations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. Materials and Methods: In total, 142 consecutive patients, who underwent surgery for perforated peptic ulcer, at a single institution, between January 2005 and October 2010 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. Results: The postoperative morbidity rate associated with perforated peptic ulcer operations was 36.6% (52/142). Univariate analysis revealed that a long operating time, the open surgical method, age (${\geq}60$), sex (female), high American Society of Anesthesiologists (ASA) score and presence of preoperative shock were significant perioperative risk factors for postoperative morbidity. Significant comorbid risk factors included hypertension, diabetes mellitus and pulmonary disease. Multivariate analysis revealed a long operating time, the open surgical method, high ASA score and the presence of preoperative shock were all independent risk factors for the postoperative morbidity in perforated peptic ulcer. Conclusions: A high ASA score, preoperative shock, open surgery and long operating time of more than 150 minutes are high risk factors for morbidity. However, there is no association between postoperative morbidity and comorbid disease in patients with a perforated peptic ulcer.

Enterprise Risk Management(ERM) is aiming at the establishment of the risk management process to prevent and cope with risks in advance and is composed of Risk Identification, Risk Assessment, Risk Response and Monitoring. It is feedback through the Risk Re-identification. This study has analysed a sample of the risk management system of an airport operating corporation, for this purpose, relevant documents and examples of overseas airports have been reviewed. It has found that corporations establishing ERM have been performing identical procedures such as the process of Identification, Assessment, Effective Reporting, Communication and monitoring and so on. The A corporation has established the process for risk management and crisis management and organized for its organization and system. The risk management has the same process such as above. In this process, when the symptoms of critical crisis have been recognized, it has been transformed into crisis management system, through which, corporate-wide response has been conducted in the process of crisis status analysis, response and follow-up management. This study expects to contribute to systematic foundation for future business continuity on the basis of risks and response procedures acknowledged by this study.

Purpose: This study was done to evaluate the experience of securing patient safety in hospital operating rooms. Methods: Experiential data were collected from 15 operating room nurses through in-depth interviews. The main question was "Could you describe your experience with patient safety in the operating room?". Qualitative data from the field and transcribed notes were analyzed using Strauss and Corbin's grounded theory methodology. Results: The core category of experience with patient safety in the operating room was 'trying to maintain principles of patient safety during high-risk surgical procedures'. The participants used two interactional strategies: 'attempt continuous improvement', 'immersion in operation with sharing issues of patient safety'. Conclusion: The results indicate that the important factors for ensuring the safety of patients in the operating room are manpower, education, and a system for patient safety. Successful and safe surgery requires communication, teamwork and recognition of the importance of patient safety by the surgical team.
