In construction industries, the problem areas in safety are different to those of manufacturing. For instance, construction safety efforts must strongly emphasize fall prevention, whereas caught-in/ between incidents and electrical shocks are common in manufacturing. This paper reports an analysis of fall incidents that lead to fatalities in 1999 and in 2000. It also provides a safety plan for fall prevention by analyzing the origins of fall incidents by their trades and locations of concern. The findings of this study are expected to contribute toward reducing fall incidents in construction industry.

기업은 대부분의 경우 보안사고가 발생하면 내부 대응절차에 따라 신속한 사고처리에 집중하고 사고원인, 문제점 및 조치결과를 최고 경영진에게 보고하면서 사고를 마무리한다. 또한 외부에서 발생한 보안사고는 그때마다 관심을 가지고 적극적으로 내부와 연결하여 문제점을 발굴하고 조치를 하는 경우와 외부의 문제로 치부하며 잠시 관심정도만 가지고 넘기는 경우도 있을 것이다. 기업은 보안사고 발생 시점에 관심과 역량을 집중하여 대응하는 것 뿐만 아니라 보안사고가 발생하지 않도록 지속적인 사고예방 활동을 하는 것이 중요하며 이를 위해 체계적이며 일관성 있고 시스템적인 방법이 제공되어야 한다. 이와 같은 목적에서 본 논문에서는 보안사고 예보시스템을 제안한다. 보안사고 예보시스템은 기업의 내부에서 일어난 직접 보안사고 뿐만 아니라, 외부에서 발생한 간접 보안사고로부터 향후 보안사고 예측에 도움이 되는 사고발생 유발인자들을 모아서 데이터베이스화하고 기업에서 가지고 있는 축적된 사고 경험과 대응 프로세스들을 시스템화하여 상호작용을 하도록 만드는 것이다. 보안사고 예보시스템은 잠재적으로 발생할 수 있는 사고의 예방조치활동에 효과적인 대안이 될 수 있을 것이다.

Background: This study aimed to identify the impacts of job stress and cognitive failure on patient safety incidents among hospital nurses in Korea. Methods: The study included 279 nurses who worked for at least 6 months in five general hospitals in Korea. Data were collected with self-administered questionnaires designed to measure job stress, cognitive failure, and patient safety incidents. Results: This study showed that 27.9% of the participants had experienced patient safety incidents in the past 6 months. Factors affecting incidents were found to be shift work [odds ratio (OR) = 6.85], cognitive failure (OR = 2.92), lacking job autonomy (OR = 0.97), and job instability (OR = 1.02). Conclusion: Patient safety incidents were affected by shift work, cognitive failure, and job stress. Many countermeasures to reduce the incidents caused by shift work, and plans to reduce job stress to reduce the workers' cognitive failure are required. In addition, there is a necessity to reduce job instability and clearly define the scope and authority for duties that are directly related to the patient's safety.

Purpose: At present, there are a variety of serious patient safety incidents related to problems in health information technology (HIT), specifically involving electronic medical records (EMRs). This emphasizes the need for an enhanced electronic medical record system (EMRS). As such, this study analyzed both the nature of and potential to prevent incidents associated with HIT/EMRS based on data from the Korea Patient Safety Reporting and Learning System (KOPS). Methods: This study analyzed patient safety incidents submitted to KOPS between August 2016 and December 2019. HIT keywords were used to extract HIT/EMRS incidents. Each case was reviewed to confirm whether the contributing factors were related to HIT/EMRS (HIT/EMRS-related incidents) and if the incident could have been prevented (HIT/EMRS-preventable incidents). The selected reports were summarized for general clarity (e.g., incident type, and degree of harm). Results: Of the 25,515 obtained reports, 2,664 incidents (10.4%) were HIT-related, while 2,525 (9.9%) were EMRS-related. HIT/EMRS-related incidents were the third largest type of incident followed by 'fall' and 'medication incidents.' More than 80% of HIT/EMRS-related incidents were medication-related, accounting for approximately one-third of the total number of medication incidents. Approximately 10% of HIT/EMRS-related incidents resulted in patient harm, with more than 94% of these deemed as preventable; further, sentinel events were wholly preventable. Conclusion: This study provides basic data for improving EMR use/safety standards based on real-world patient safety incidents. Such improvements entail the establishment of long-term plans, research, and incident analysis, thus ensuring a safe healthcare environment for patients and healthcare providers.

Service attributes are important for customer perceptions of service quality. However, in spite of huge amount of research, the role of service attributes as satisfiers and dissatisfiers in service encounters is not understood well enough. An empirical investigation is conducted concerning a problem resolution service in the telecommunication industry. We use both qualitative and quantitative service performance data to describe and analyze how critical incidents can be used to identify and understand which service attributes are perceived as satisfiers and dissatisfiers. Our study reveals that there is a subset of critical incidents, so called critically critical incidents, which are perceived differently and are different in content compared to critical incidents. These incidents are extremely rich of information and have the possibility to reveal the real satisfiers and dissatisfiers in a service encounter.

Hydropower is now changing its role from the energy generator into the most powerful and reliable tool for stabilizing the electrical network, especially under the increase of intermittent power sources like wind-power and solar-power. Although the hydropower plants are the most robust generating facilities, they are not immune from unexpected severe incidents having long downtime, considerable restoration cost and sometimes fatalities. The present paper provides some study results about severe incidents in the conventional hydropower plants, mainly about the flood, fire and electro-mechanical troubles, except for the incidents of civil facilities. It also provides some possible scenarios which may lead some measures how to avoid such incidents. Finally, it provides some comprehensible recommendations to avoid severe incidents based on experiences.

In this paper, we propose an analysis framework to capture the trends of information security incidents and evaluate the security policy based on the incident analysis. We build a big data from news media collecting security incidents news and policy news, identify key trends in information security from this, and present an analytical method for evaluating policies from the point of view of incidents. In more specific, we propose a network-based analysis model that allows us to easily identify the trends of information security incidents and policy at a glance, and a cosine similarity measure to find important events from incidents and policy announcements.

Purpose: This study aims to describe the characteristics of safety incidents and factors associated with injury for patients with Home Mechanical Ventilation (HMV) at the hospital. Methods: This is a retrospective study. Data were collected from the work log of respiratory home care nurses and the patients' electronic medical records were investigated. In order to compare group differences, independent t-test and χ² test were used. Associated factors with injury development were identified by generalized mixed modeling analysis controlling for age and gender. Results: A total of 304 patients on HMV were included in this study, among which 129 (42.4%) experienced 352 HMV-related incidents. Mean frequency of incidents for each patient was 5.11±3.98, ranged from 1 to 15 times. In 19.0% of the incidents, injury was developed. Types of incident and persons involved in the incidents were significantly associated with the patient's injury. In the case of the safety incidents, patient's injury was significantly higher in accidents caused by respiratory circuit problems compared to those caused by problems with the ventilator operation by the medical staff (coefficient=1.25, p=.020). In addition, in the case of those involved in the safety incidents, patient's injury was significantly higher in the accident caused by the patient family members or caregivers than that caused by the medical personnel (coefficient=1.25, p=.019). Conclusion: In order to minimize injury caused by incidents in patients with HMV, hospitals need to provide systemic education to their medical staff and caregivers to enhance awareness of the importance of reporting and safety management.

본 연구에서는 CA(Cellular Automata)규칙을 이용하여, 돌발상황의 영향을 분석할 수 있는 시뮬레이션 모형을 구축하고, 실시간 자료인 VDS 자료와 현장측정 자료를 이용하여 시뮬레이션 모형을 검증하였다. 이렇게 구축된 시뮬레이션 모형을 이용하여, 고속도로상에서 돌발상황이 발생하였을 때의 영향을 분석하였다. 그 결과는 5% 신뢰구간에서 통계적으로 유의함으로 나타났다. 돌발상황의 영향을 분석하기 위해서 돌발상황의 지속시간과 교통량의 변화에 따른 돌발상황의 유형을 분류하였고, 각각의 돌발상황 유형에 따른 영향을 분석하였다. 이때 돌발상황에 의한 영향은 구간 통행시간의 변화와 혼잡 지체시간의 변화를 통해서 분석하였다. 결과에 따르면, 교통량이 적을 때는 교통류가 돌발상황에 의해서 거의 영향을 받지 않았고, 교통량이 증가함에 따라, 돌발상황에 의한 영향이 점점 더 커지는 것으로 나타났다. 또한, 교통량이 2000대/시를 넘어설 때는 돌발상황이 발생하지 않더라도, 교통량의 증가에 따라 혼잡지체가 자연스럽게 발생하는 것으로 나타났고, 돌발상황이 45분 동안 계속될 경우에는 약 425∼722대·시의 지체가 발생하였다.
