This study investigated human error characteristics of the 42 fatal industrial accidents reported by staff members of Korea Industrial Safety Corporation. Various types of human error were judged to be primary contributing factors in about 74 percent of the cases. Most of human error made by involved industrial operators resulted from two types of mistakes: (1) mistake in judgement of work situation, and (2) omission in daily check. It was concluded that preparation/observance for work procedure manuals, danger predication training and enforcement/Education of daily check routine would be effective preventive tools for these types of human error attributable to fatal industrial accidents.

The purpose of this paper is to know the cause of a rapidly fatal disease of Korean native cattle commonly occurred in the farm-houses in Gyeonsangbugdo district and the rest of the country. The author diagnosed this acute fatal disease of Korean native cattle as enterotoxemia due to Clostridium perfringens based on the clinical, epidemiological and pathological findings.

Purpose: The objective of this study was to develop a new scoring tool that is comprehensively applicable and predicts fatality within 24 h of intoxication. Methods: This was a cohort study conducted in two emergency medical centers from 2011 to 2012. We identified factors associated with severe/fatality. Through a discriminant analysis, we devised the aBIG (age, Base deficit, Infection, and Glasgow coma scale) score. To compare the ability of aBIG to predict intoxication severity with that of previous scoring systems such as APACHE II, MODS, SAPS IIe, and SOFA, we determined the receiver operating characteristic curves of each variable in predicting severe-to-fatal toxicity. Results: Compared with the mild/moderate toxicity group (n=211), the severe/fatal group (n=143) had higher incidences of metabolic acidosis, infection, serious mental change, QTc prolongation and hepato-renal failure. Age, base deficit, infection-WBC count, and Glasgow Coma Scale were independently associated with severe/fatal poisoning. These variables were combined into the poisoning "aBIG" score [$0.28{\times}$Age group+$0.38{\times}WBC$ count/$10^3+0.52{\times}$Base deficit+$0.64{\times}$(15-GCS)], which were each calculated to have an area under the curve of 0.904 (95% confidence interval: 0.868-0.933). The aBIG poisoning score had an equivalent level of severity predictability as APACHE II and a superior than MODS, SOFA, and SAPS IIe. Conclusion: We developed a simplified scoring system using the four variables of age, base deficit, infected leukocytosis, and GCS. The poisoning aBIG score was a simple method that could be performed rapidly on admission to evaluate severity of illness and predict fatal severity in patients with acute intoxications.

건설업에서의 재해는 수십 년 동안 다른 산업보다 많이 발생하였기 때문에, 건설업에서의 재해는 반드시 줄여야 한다. 이러한 문제를 해결하기 위해서 작업분류체계(WBS) 및 위험분류체계(RBS)를 제시하였다. WBS와 RBS는 계층적 구조로 작업 및 위험 단위를 쉽고, 빠르게 찾을 수 있다. 그래서 본 연구에서는 건설업에서의 재해를 예방하기 위해 통합 WBS-RBS 프레임워크를 개발하고자 한다. 연구의 순서 다음과 같은 3단계로 진행되었다. ① 데이터 수집 ② 데이터 분류 ③ 통합 WBS-RBS 프레임워크 개발 순으로 진행되었다. 연구의 결과 가장 사고가 많이 발생한 건물용도, 건설공종 및 재해요인을 제시할 수 있었다. 연구 결과를 통해 의사결정자는 건물용도, 건설공종, 및 재해요인의 위험 수준을 고려할 수 있다.

This study analyzes the differences in definitions and concepts of terms used in the statistical indicators of fatal occupational injuries per 100,000 workers among countries included in the ILOSTAT data explorer. In addition, improvement measures focusing on the limitations in international comparison are proposed. Five countries-the Republic of Korea, Germany, Japan, United Kingdom, United States-- were comparatively analyzed. These countries were selected according to the significance of differences in their definitions of workplace injuries, workers, and compensation insurance, and their reporting systems. Considering these differences before directly comparing statistical indicators of fatal occupational injuries per 100,000 workers among countries is necessary because the range of comparison groups and the definition of fatal occupational injury are different for each country. While one can also compare trends by country, it is necessary to investigate beforehand whether the criteria and methods for processing statistics have changed. Misinterpretation can be minimized by properly understanding the process and limitations of fatal occupational statistical indicators that may differ from country to country.

South Korea's industrial injuries are decreasing overall in the last 32 years. Nevertheless, the fatal occupational injury rate is still higher than in developed countries. This study was conducted to help prevention strategies of occupational injuries for the Republic of Korea. Fatal occupational injury rates were obtained from "Industrial Accident Analysis"of the Korean Ministry of Labor. Poisson regression was used to assess time trends. Socioeconomic indicators were obtained from the Korea Labor Institute and the Statistics Korea. Fatal occupational injury rates were adjusted by year, and Pearson correlation analysis was used to assess the relationship between the socio-economic indicators and occupational injuries. In 1975, fatal occupational injury rate was 54.8 per 100,000 workers. With somewhat up and down, it was decreased to 21.0 in 2006. An annual rate of change for the years 1975-2006 was - 1.83%, and for the years 2002-2006 was -5.02%. As economic growth rate, paricipation rate for the age less than 25 and hours of work per week or year increased, fatal occupational injury rate also increased. Conversely, as GDP per capita, paricipation rate or employment rate for female, paricipation rate for the age 25 or more, hourly compensation costs for production workers and services output as percent of GDP increased, fatal occupational injury rate decreased. By the development of safety techniques and the adoption of more legislative constraints, developed economy reduce occupational injuries. Conversely, economic growth may raise occupational injuries. Therefore, prevention strategies are needed to manage both of them. We need to make an effort to prevent occupational injuries due to not only sexual differences, but also job differences between male and female. Preventive strategies are needed to consider the characteristics of younger workers. Addition to wage, other appropriate variables for work condition should be considered together. Extending work hours is need to be regulated with systemic methods.

본 연구는 2000년 이후 대형교통사고 발생지점 112건의 자료를 이용, 다양한 교차 및 빈도분석을 통해 대형교통사고와 도로 기하구조의 관계를 규명하고, 이를 토대로 대형교통사고 심각도 모형을 구축하였으며, 주행안전성 향상을 위해 720회의 컴퓨터 모의실험으로 다음과 같은 결론을 얻을 수 있었다. 첫째, 교차 및 빈도분석의 결과 커브구간에서 43.7%, 종단경사 기타조건에서 60.7%, 곡선반경 0~24m 구간에서 57.2%, 편경사 0.1~2.0% 구간에서 83.9%, 편도2차로 도로에서 49.1%, 차종별로는 승용(33.0%), 화물(20.5%), 버스(14.3%) 순이었으며, 편경사 설치 유 무가 대형교통사고 발생에 가장 큰 영향을 주는 것으로 분석되었다. 둘째, 순서형 프로빗 모형(Ordered Probit Model)을 이용하여 다양한 도로조건에서의 피해 예측이 가능한 대형교통사고 심각도 모형을 개발하였으며, 개발된 모형을 기반으로 도로의 위험성을 사전에 예측하고, 대책 마련이 가능토록 기여 하였다. 셋째, 컴퓨터 모의실험(Simulation) 결과, 이미 대형교통사고가 발생한 장소에 편경사를 설치했을 경우 약 85% 이상의 지점들에서 대형교통사고가 발생하지 않는 개선효과가 있는 것으로 분석되었으며, 이 분석결과를 통해 도로의 구조 시설 기준에 관한 규칙(해설 및 지침)의 편경사 설치 예외규정을 더욱더 강화시킬 필요가 있다고 사료된다.

건설 산업은 중대 재해가 지속적으로 발생하고 있는 실정이다. 이러한 이유로는 많은 건설 현장의 작업이 고소작업과 옥외작업의 악천후의 작업과 같은 위험한 조건에서 수행되기 때문에 다른 산업에 비해 재해의 빈도와 강도가 심각하고, 이로 인해 안전사고에 노출된다. 소규모 건설현장은 사망재해의 위험이 매우 크지만 소규모 건설현장의 사망재해로 이어지는 다중 요인의 연구는 부족한 것으로 드러났다. 따라서 건설업의 사망재해를 줄이기 위해 본 연구에서 소규모 건설현장에서 발생한 1,438건의 사망재해 사례를 분석하고, 소규모 건설현장에서 치명적인 사고를 일으키는 10가지 요인으로 연관규칙 분석을 수행하였으며, 연관규칙 분석으로 나타난 결과를 기초로하여, 본 연구는 소규모 건설현장의 사망재해를 줄이기 위한 대책에 대해서도 논의하였다. 연구 결과에 대해서는 결과에 동의하는 전문가들에게 설명하여 인터뷰 형식으로 진행하였다. 본 연구는 소규모 건설현장 근로자를 위한 안전 정책 및 안전관리 이론에 기여 할 수 있다.

Paraquat poisoning is a fatal type of herbicide intoxication. It is characterized by multi-organ failure and pulmonary fibrosis with respiratory failure. Intravenous and intramuscular injection of paraquat is rarely described. However, We encountered two fatal cases of acute poisoning caused by paraquat injection. Two patients were admitted to our emergency unit after intravenous and intramuscular injection of 23.8% paraquat (about 476 mg of paraquat). A 37-year-old man diluted 2 ml of 23.8% paraquat solution with 1 ml of normal saline and injected it both intravenously into his left antecubital fossa and intramuscularly into his abdomen in a suicide attempt. He died 5 days later from respiratory failure and acute renal failure. A 92-year-old man was injected intravenously into his right antecubital fossa by his grandson with 2 ml of 23.8% paraquat solution diluted with 1 ml of normal saline. He died 2 days later from early circulatory collapse and multi-organ failure (metabolic acidosis, acute renal failure, coagulopathy). Intravenous and intramuscular injection with a small quantity of paraquat resulted in fatal toxicity in our patients.
