도로교통안전관리공단(2005)이 발표한 자료에 의하면 우리나라의 2004년 총 교통사고 건수는 220,755건이며, 사망자는 6,563명으로 조사되었으며, 이중 교차로에서의 사고가 1/4 이상을 차지하고 있는 것으로 보고하고 있다. 교차로 교통사고는 통행 특성상 단일로에 비하여 많은 상충점을 가지고 있어 사고의 잠재성이 높은 것이 사실이다. 교통상충기법은 다양한 측면에서 기존의 교통사고 자료를 활용한 분석방법보다 그 활용도가 높으며, 보다 많은 필요성이 제기되고 있지만, 기존의 교통상충기법은 신호교차로에서 발생하는 다양한 상충유형에 대해 상충발생의 심각도를 고려하지 못하는 단점을 가지고 있었다. 이에 본 연구에서는 신호위반시 발생하는 대향좌회전 상충의 유형에 대하여 상충심각도를 고려한 새로운 상충판단기준을 정립하였으며, 이를 인천광역시의 교통사고발생이 빈번한 교차로를 선정하여 상충수와 심각도를 분석하였다. 취득한 대상 교차로의 영상을 3시간 동안 분석한 결과, 총 41건의 대향좌회전상충이 발생하였으며, 각각의 심각도는 '상'이 3건, '중'이 10건 그리고 '하'가 28건 발생한 것으로 확인되었다. 신호교차로에서 발생하는 상충유형의 심각도 연구가 필요한 근거는 보다 교차로의 안전도를 평가하는데 있어 보다 정밀하게 접근하고자 함이며, 상충의 심각도가 고려되지 못한 기존의 상충발생의 건수만을 이용한 연구로는 상충연구가 가지는 의의가 제한적이기 때문이다. 또한, 본 연구의 결과는 대향좌회전상충유형을 비롯한 신호교차로에서 발생하는 다양한 상충유형의 심각도 판단기준을 정립하는데 중요한 기초자료가 될 것으로 판단된다.

Purpose: The aim of this study was to identify clinical outcome and characteristics of trauma patients via emergency medical services (EMS). Methods: Medical records of the trauma patients visiting the emergency department were retrospectively collected and analyzed from January 2015 to June 2016 in the single institution. Of 529 registered patients, 371 patients were transported by - were enrolled. The parameters including age, gender, injury mechanism, Glasgow coma scale on arrival, presence of shock (systemic blood pressure <90 mmHg) on arrival, time to arrival from accident to emergency room (ER), need for emergency procedures such as operation or angioembolization, need for intensive care unit (ICU) admission, injury severity score (ISS), the trauma and injury severity score, revised trauma score (RTS), length of stay, and mortality rate were collected. The SAS version 9.4 (SAS Institute, Cary, NC, USA) was used for the data analysis. Results: Arrival time from the field to the ER was significantly shorter in EMS group. However, overall outcomes including mortalities, length of stay in the ICU and hospital were same between both groups. Age, ISS, RTS, and injury mechanisms were significantly different in both groups. ISS, RTS, and age showed significant influence on mortality statistically (p<0.05). Conclusions: The time to arrival of EMS was fast but had no effect on length of hospital stay, mortality rate. Further research that incorporates pre-hospital factors influence clinical outcomes should be conducted to evaluate the effectiveness of such a system in trauma care of Korea.

This study suggests systematic procedures to improve safety policies on prevention of industrial accidents associated with industrial machines and devices. Specifically, new method of cause analysis of industrial accidents associated with industrial machines and devices is suggested and the related accident data are re-analyzed. Effectiveness of direct safety regulations such as safety certification, self-declaration of conformity, safety device regulation and safety inspection of industrial machines and devices are also analyzed. Based on those analysis results, transition from the current user-oriented safety device regulation to more balanced direct regulations on both manufacturer and user is suggested. Together with severity and frequency of industrial accidents, unit severity and unit frequency need to be taken into account to further assess the risk associated with a particular industrial machine or device. Balance between safety regulations will be realized by proper adjustment of lists of safety certification and inspection, and certification and inspection standards. This will also guarantee the maximum benefit over cost in such safety regulations.

Recently, the criteria for assessing industrial accidents have been replaced by the mortality rate. It was found that the number of deaths from excavation work was the highest among construction machinery. The risk assessment is being conducted, however the industrial accident mortality rate has not decreased. Accordingly, this study aims to provide the basic for the create of a risk assessment model specialized in construction work at excavator. It provides absolute value from the risk model which is capable of delivery the probability of a disaster. In addition, we provide a relative risk model that compares the risk through scores between detailed works. The relative risk model is combined by likelihood and severity; the likelihood indicates the frequency of accidents and the severity indicates seriousness of fatal accidents. A variable that reflects the conditions of the construction site was added to the risk assessment model based on past disaster cases. And using the concepts of probability and average, the risk assessment process was quantified and used as an objective indicator. Therefore, the model is expected to reduce disasters by raising the awareness of disasters.

Purpose: This study was conducted to identify and analyze the types, characteristics, and frequency of patient safety accidents among hospitalized children. Methods: The data were collected from patient safety reports for 0-19-year-old patients from the National Health Insurance Corporation (NHIC) from January 1, 2016 through December 31, 2017. Using Excel software, a pivot table was used to classify and analyze the safety incidents, severity frequency, and characteristics of hospitalized child patients. Results: A total of 254 accident cases were reported involving child patients. The types of reports included medication accidents, falls, test errors, and others. Medication accidents accounted for 47.2% of the total reported cases. Regarding the severity of reported risk, there were no complications nor sequelae in 80.4% of the cases. Conclusion: This study is significant for systematically analyzing and reporting data reported about safety accidents among hospitalized children. These results will contribute further to preventing safety accidents in hospitalized children and to creating a desirable patient safety culture.

Purpose: The purpose of this study was to analyze factors affecting fall prevention activities of emergency room (ER) nurses based on their health belief factors (perceived susceptibility, perceived benefits, perceived severity, perceived barriers, and cues to action). Methods: The study design was a descriptive survey using questionnaires which were given to 127 emergency room nurses from two regional emergency medical centers, four local emergency medical centers, and two local emergency medical facilities. Data were analyzed using descriptive analysis, t-test, one-way ANOVA with LSD test, Pearson correlation, and multiple regressions. Results: ER nurses' fall prevention activities had a mean of $3.78{\pm}0.50$. Eight individual characteristics and health belief factors accounted for 30.8% of the fall prevention activities. Fall prevention activities were found to be positively affected by emergency medical facilities, perceived benefits, and cues to action and negatively affected by factors, such as ER career and perceived severity. Conclusion: The results indicate that it is necessary to formulate a plan for enhancing perceived benefits and cues to action to improve fall prevention activities. In addition, fall prevention activities should be encouraged for ER nurses who have worked in local medical institutions for less than 1 year or more than 5 years.

Purpose: Many factors influence the occurrence and severity of geriatric trauma, and regional weather is regarded as one factor that influences geriatric trauma. In this study, to predict the type, severity, and incidence of geriatric trauma patient, we analyzed the influence of regional weather on geriatric trauma. Methods: The subjects of our investigation were trauma patients over sixty-five years of age who visited the Emergency Department (ED) of Yeungnam University Hospital during a one-year period. We retrospectively reviewed the medical charts of 436 geriatric trauma patients, and the data were analyzed by using SPSS 12.0 for Window. The weather was based on data from the Korea Meteorological Administration. Results: The average age was 72.8 years old, and the ratio of males to females was 1:1.1. The mean spell out ISS was 10.8, and no difference was found between males and females. Slips were the most common cause of trauma. The largest numbers of aged trauma patients, 46, visited the ED in May, and the smallest number of such patients, 24, visited the ED in December. In addition to, summer saw the largest number of aged trauma patients. The type of trauma, the Injury Severity Score, and the number of patients had no relationship with season. On sunny days, the ISS was larger in patients who had hypotension and who had tachycardia. On rainy day, the ISS was larger in male patients and cultivator accident patients. The number of patients was larger on partly cloudy days. Conclusion: In spring and summer and on partly cloudy days, we must be prepared to treat aged traumatized patients in the E.D. On rainy days, visual sensation, tactual sense, and acoustic sense must be closely examined. In addition,on rainy day, aged male traumatized patients or cultivator accident patients must to be closely observation.
