Purpose. The purpose of this study was to develop and evaluate an error reporting promoting program(ERPP) to systematically reduce the incidence rate of nursing errors in operating room. Methods. A non-equivalent control group non-synchronized design was used. Twenty-six operating room nurses who were in one university hospital in Busan participated in this study. They were stratified into four groups according to their operating room experience and were allocated to the experimental and control groups using a matching method. Mann-Whitney U Test was used to analyze the differences pre and post incidence rates of nursing errors between the two groups. Results. The incidence rate of nursing errors decreased significantly in the experimental group compared to the pre-test score from 28.4% to 15.7%. The incidence rate by domains, it decreased significantly in the 3 domains-"compliance of aseptic technique", "management of document", "environmental management" in the experimental group while it decreased in the control group which was applied ordinary error-reporting method. Conclusion. Error-reporting system can make possible to hold the errors in common and to learn from them. ERPP was effective to reduce the errors of recognition-related nursing activities. For the wake of more effective error-prevention, we will be better to apply effort of risk management along the whole health care system with this program.

The objective of this study is to explore the whole process of fraud risk management strategies that should be implemented by the organizations. Secondly, this study discusses the governance issues that arise at each stage of the process. For the purpose of this study, a content analysis of previous literatures is used as a technique for gathering data. This process usually involves codifying qualitative and quantitative information into pre-defined categories in order to derive patterns in the presentation and reporting of information. Based on our content analysis, we found that the fraud risk management process should be made of at least five stages which are inculcating the culture of managing risks in an organization, identifying the risks, evaluating the risks, determining preventive actions and implementing and reviewing stages. Our extended analysis of the fraud risk management process finds that a lot of governance issues arise in the fraud risk management process that should be solved by regulators and companies in order to ensure that fraud risk management process is embedded as corporate culture, not merely as a process. Among them are how to create the risk culture in an organization and whether auditors and risk management committees identify risks from each available source.

Objectives: Exposure Assessment for workplace hazards where the exposure level is below occupational exposure limits(OELs) has been performed without considering either the degrees of risk or exposure levels and has failed to lead to intervention in many cases. The objective of this study was to suggest and test an application framework for risk assessment methodology under the current exposure assessment system in Korea. Materials: First, we investigated the exposure assessment systems in Korea and other countries. To adopt some risk assessment techniques, we also analyzed risk assessment systems and compared them to exposure assessment systems. A few suggestions were made. We held a public hearing during an industrial hygiene conference and took surveys using a questionnaire. Results: The first suggestion was to implement the risk assessment and exposure assessment through a "one-stop" system. In that case, one expected question would be who has been doing the jobs so far. In most cases, industrial hygiene consulting services or laboratories have been performing exposure assessment for business owners. Business owners are required to perform risk assessment. As two different groups of people will be required to implement two things in a one-stop system, they need to share information. As an information vehicle to share information, commonly filed survey checklists were suggested. The second suggestion was to categorize exposure level into four groups instead of the current binary divisions based on OELs. In the risk assessment system, exposure level is divided into four groups utilizing the cut-points of 10%, 50%, and 100% of OELs. The same schema can be adopted in the exposure assessment system and different levels of requirements can be assigned for each group. The third suggestion was regarding the regulation system. To provide the suggestions some thrust toward being implemented in the field, changes should be made in the legal system. Two different types of new exposure assessment result reporting forms were suggested. Some investigations such as an ergonomic survey are officially accepted as risk assessment under the current legal system. A few items were suggested to be included in the exposure assessment result reporting to be accepted as risk assessment. A pilot study in two small factories was performed and pointed out the strengths and weakness of our suggestions. Conclusions: Discussions and studies on the improvement of the exposure assessment system have been held for decades and no tangible changes have yet been made. We hope this result can help realize healthy lives for workers in Korea.

Purpose: Rodent models have emerged as an alternative to established larger animal models for peri-implantitis research. However, the construct validity of rodent models is controversial due to a lack of consensus regarding their histological, morphological, and biochemical characteristics. This systematic review sought to validate rodent models by characterizing their morphological changes, particularly marginal bone loss (MBL), a hallmark of peri-implantitis. Methods: This review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A literature search was performed electronically using MEDLINE (PubMed), and Embase, identifying pre-clinical studies reporting MBL after experimental peri-implantitis induction in rodents. Each study's risk of bias was assessed using the Systematic Review Center for Laboratory animal Experimentation (SYRCLE) risk of bias tool. A meta-analysis was performed for the difference in MBL, comparing healthy implants to those with experimental peri-implantitis. Results: Of the 1,014 unique records retrieved, 23 studies that met the eligibility criteria were included. Peri-implantitis was induced using 4 methods: ligatures, lipopolysaccharide, microbial infection, and titanium particles. Studies presented high to unclear risks of bias. During the osseointegration phase, 11.6% and 6.4%-11.3% of implants inserted in mice and rats, respectively, had failed to osseointegrate. Twelve studies were included in the meta-analysis of the linear MBL measured using micro-computed tomography. Following experimental peri-implantitis, the MBL was estimated to be 0.25 mm (95% confidence interval [CI], 0.14-0.36 mm) in mice and 0.26 mm (95% CI, 0.19-0.34 mm) in rats. The resulting peri-implant MBL was circumferential, consisting of supra- and infrabony components. Conclusions: Experimental peri-implantitis in rodent models results in circumferential MBL, with morphology consistent with the clinical presentation of peri-implantitis. While rodent models are promising, there is still a need to further characterize their healing potentials, standardize experiment protocols, and improve the reporting of results and methodology.

갑상선 결절 환자에서 초음파 검사는 일차적 영상 진단법으로 정립되어 있으며 치료 결정을 위한 핵심적인 진단 역할을 갖는다. Korean Thyroid Imaging Reporting and Data System(이하 K-TIRADS)는 초음파 유형에 기초한 암 위험도 분류체계로서 실시간 초음파 검사를 시행하면서 쉽게 결절 진단이 가능하다는 장점을 갖고 있다. 개정된 2021 K-TIRADS는 결절의 초음파 분류 기준을 보다 명확히 하였고, 고위험 갑상선암의 의심 소견이 없는 환자에서 병리진단검사를 결정하는 결절 크기 기준을 개정하여 불필요한 병리진단검사를 최소화하고 적절한 갑상선암 진단 예민도가 유지되도록 개정하였다. 갑상선영상의학진료는 갑상선 결절 환자의 진단 및 비수술적 치료를 수행하는 중요한 임상적 역할을 가지고 있으며, 적절한 환자 진료를 위해서는 표준적 진료 지침에 근거하여 진료가 수행되어야 한다.

최근 재무제표분석을 통하여서 기업을 진단하려고 하는 다양한 학문적인 연구와 실질적인 적용이 실행되고 있다. 특히, 최근 새롭게 변경된 회계기준인 한국채택 국제회계기준(K-IFRS: Korea - International Financial Reporting Standards)에 따라서 제무제표분석에도 변화가 발생하고, 그에 따라서 기업 진단도 새롭게 변화되어야 하는 상황이 되었다. 이에 현재, 금융권에서도 관심을 갖고 있는 매출채권 처리의 변화에 따라서 발생하는 재무제표상의 진단 및 분석을 반영하여서 처리하는 새로운 진단모형의 필요성이 대두되었다. 특히, 최근 모뉴엘이라는 기업의 매출채권을 이용한 금융스캔들의 영향으로 이러한 연구가 더욱 활발하게 진행되고 있다. 매출채권은 일반적 상거래에서 발생하는 신용채권 으로서, 기업이 만기까지 보유하거나 만기 전에 양도가 가능한 금융 상품이다. 기업이 매출 채권을 할인하여 양도할 경우에 매출채권 할인을 매각거래로 처리하고, 할인료에 해당하는 금액을 매출채권처분 손실로 처리하며, 해당 거래를 우발 채무로 공시하였다. 그러나, K-IFRS 하에서는 모든 위험과 보상이 이전되지 않는 한 매출채권 할인을 차입거래로 인식한다. 이는 기업 부채의 증가로 기업가치에 영향을 미치게 된다, 이 논문에서는 매출채권 할인이 실질적으로 기업가치에 부정적인 영향을 미치는지 추정하는 지능형진단시스템을 제안한다. 본 논문에서는 매출채권 할인이 주가에 미치는 영향을 인공지능기법인 사례기반추론(case based reasoning)과 자기조직화지도 (self-organizing maps)기법을 통하여 진단 모형을 구축하였다.

Purpose: This is a pilot study to identify patient safety risk factors and strategies for patient safety management perceived by nurses. Methods: Data were collected and analyzed with an open questionnaire from April to May 2005, targeted on 100 nurses working in two hospitals. The issues were 'what are risk factors for patients, nurses, and other medical practitioners? How do they prevent with the aftermath of risk factors, causes of incidents?' For data analysis, types and frequency of risk factors were worked out, using the Australian Incident Monitoring System Taxonomy. Results: The types of patient safety risk factor perceived by nurses were as follows ; therapeutic devices or equipment, infrastructure and services (29.5%), nosocomial infections (16.3%), clinical processes or procedures (15.4%), behavior, human performance, violence, aggression, security and safety (12.2%), therapeutic agents (9.7%), injuries and pressure ulcers (8.7%), logistics, organization, documentation, and infrastructure technology (5.6%). Strategies for patient safety included training of prevention of infection, education about safety management for patients and medical professionals, establishment of reporting system, culture of care, pre-elimination of risk factors, cooperative system among employees, and sharing information. Conclusion: These results will be used to provide evidences for patient safety management and educational program.

Background: This study aimed to identify the validity of breast cancer symptom questionnaire of worker's special health examination and its relationship with breast ultrasonography findings in young female night workers. Methods: The breast cancer symptom questionnaire data of worker's special health examination and breast ultrasonography results in young female shift workers who worked in one electronic manufacture company were collected from 2014 to 2018. Results: Of the 857 workers, 18 had a Breast Imaging Reporting and Database System category 4 or higher. Among other variables, shift work tenure alone was associated with the risk of having a Breast Imaging Reporting and Database System category higher than 4. The sensitivity, specificity, positive predictive value, and negative predictive value of the symptom questionnaire were 16.7%, 87.7%, 2.8%, and 98.0%, respectively. Conclusion: The current breast cancer symptom questionnaire of the worker's special health examination is inappropriate due to its low sensitivity and positive predictive value. In the future, female night workers will need alternative measures for more accurate screening for breast cancer.

This paper examines whether the combination of risk management and audit committee functions are associated with audit report lag. Audit report lag is considered an important aspect of the financial reporting. The financial reports are the main source of information for shareholders through which they make their decisions and it assists in reducing the information asymmetry. As the internal control mechanisms substitute the external ones, the internal board committees formed by the board of directors can reduce the audit work and, consequently, reduces the audit report lag. A key committee is the risk management committee. This paper examines whether the combination of risk management and audit committee functions are associated with audit report lag. We posit that a combination of such functions in one committee refereed as audit committee affects the audit report delay. Data were obtained from 198 manufacturing companies listed on the Saudi Stock Exchange (Tadawul) for the years 2016-2018. A pooled OLS regression analysis shows that a combination of risk management and audit committee functions in a stand-alone committee named "audit committee" is associated with longer audit report lag. The outcomes suggest companies should prioritize the establishment of standalone risk management committee with activities separated from those of audit committees.
