The fatality rate is used to estimate each country's risk level. However, the fatality rate is calculated using the number of fatal accidents and workers, which is collected differently across countries. It is therefore problematic to use these numbers in an equivalent way. This study proposes a new approach for calculating the number of full-time equivalent workers when evaluating individual countries' fatality rate by suggesting an equivalent condition for the calculation of the number of full-time equivalent workers. This study proceeds in three steps: (i) analysis of the fatality rate among various countries; (ii) fatality rate calculation using the full-time equivalent workers; and (iii) comparison of the fatality rate among various countries. The study found that for the fatality rate based on national data, the fatality rate in South Korea (1.72‱) is 10 times higher than that in United Kingdom (0.17‱). However, according to the number of full-time equivalent workers, the fatality rate in South Korea (1.86‱) was three times higher than that in the United Kingdom (0.56‱). These findings reveal a difference in the fatality rate depending on the method used to calculate the number of full-time equivalent workers. Therefore, the number of full-time equivalent workers must be calculated for each country to accurately compare the fatality rate. Ultimately, the study's results highlight the need for clearer standards in the assessment of the fatality rate by country in international organizations such as the ILO.

Objectives: This study is aimed to illustrate the status of the occupational accident rate, fatality rate, and musculoskeletal disorder rate by safety and health management type in workplaces. Methods: In order to analyze the status of the occupational accident rate, fatality rate, and musculoskeletal disorder rate of different safety and health management types in workplaces, selected data from the Occupational Safety and Health Research Institute were used. Results: The occupational accident rate in workplaces where safety and health managers had been appointed was lower than in those where safety and health management was entrusted to other organizations, while the result was the opposite in regards to the fatality rate per 10,000 workers caused by accident. However, the occupational fatality rate per 10,000 workers in workplaces where safety and health managers have other roles was 426% higher than those where safety and health management was entrusted to other organizations. Moreover, the musculoskeletal disorder rate of the workplaces where safety and health managers have other roles was 15% higher than those where health management was entrusted to other organizations. Conclusions: It is necessary to review the effectiveness of systems in which safety and health managers can concurrently engage in other roles.

Bacterial species, Bacillus amyloliquefaciens and Lactobacillus species (L. sp.5-1), are known to inhibit the growth of pathogenic bacteria and fungi. Metarhizium anisopliae is a pathogenic fungal species which causes fatal damage to P. brevitarsis populations. Therefore, we investigated the inhibitory effect of B. amyloliquefaciens and L. sp. 5-1 on M. anisopliae induced fatality rates in P. brevitarsis. Samples of M. anisopliae-infected sawdust were treated with strain B. amyloliquefaciens KACC10116, strain L. sp. 5-1 KACC19351, and a combination of the two. P. brevitarsis were fed treated sawdust samples, and their subsequent fatality rate was monitored. The fatality rate fell below 1.5% after 10 days and decreased by approximately 40% after 15 days. On average, the fatality rate decreased by 20%, compared to the control. The difference in the decrease in fatality rate between B. amyloliquefaciens treatment and L. sp. 5-1 treatment was not significant. Results indicate that both strains exhibit high anti-fungal activity, which may be useful in environmental purification efforts. These strains may be used for effective prevention of fungal infection in P. brevitarsis.

A reliable prediction model of national occupational accident fatality rate can be used to evaluate level of safety and health protection for workers in a country. Moreover, the socio-economic aspects of occupational accidents can be identified through interpretation of a well-organized prediction model. In this paper, we propose a machine learning based relative comparison methods to predict and interpret a national occupational accident fatality rate based on socio-economic indicators. First, we collected 29 years of the relevant data from 11 developed countries. Second, we applied 4 types of machine learning regression models and evaluate their performance. Third, we interpret the contribution of each input variable using Shapley Additive Explanations(SHAP). As a result, Gradient Boosting Regressor showed the best predictive performance. We found that different patterns exist across countries in accordance with different socio-economic variables and occupational accident fatality rate.

Korea has performed strategies for the third industrial accident prevention in order to minimize industrial accident. However, the occupational fatality rate and industrial accident rate appears to be stagnated for 11 years. Therefore, this paper forecasts the occupational fatality rate and industrial accident rate for 10 years. Also, this paper applies regression method (RA), exponential smoothing method (ESM), double exponential smoothing method (DESM), autoregressive integrated moving average (ARIMA) model and proposed analytical function method (PAFM) for trend of industrial accident. Finally, this paper suggests fundamental strategies for industrial accident prevention by forecasting of industrial accident rate in the long term.

This survey was carried out to investigate the fatality of the newborn beef calves in three ranches in Cheju area. The results were summarized as follows : 1. The fatality rate was 5.8%(67 calves) from the total 1, 160 calves examined. 2. There were pneumonia(46%), enteritis(16%), suckling disorder(13%), theileriasis (4%). and hypomagnesemia(4%) in dead calves. 3. Most of dead calves(78%) with 52cases died within 30days postparturition. 4. Bacteria-induced fatal diseases in newborn calves within 30 days postparturition might be closely associated with maternal immunity by the lack of immnunoglobalin of strum.

Objectives: To analyze underlying disease, fatality rate and the major causes of death of in-patients with malignant tumors in Sichuan Cancer Hospital. Methods: Clinical data of in-patients from 2002 to 2012 were retrospectively analyzed. Results: The top 10 tumors (82.0%of the total) of the malignant tumors of the in-patients were lung, cervical, esophagus, breast, colorectal, nasopharynx, liver and gastric cancers, lymphomas and ovarian cancers. The overall fatality rate was 2.7% during these eleven years, 3.4% and 2.0% for male and females, respectively with statistical significance for the difference (${\chi}^2$=164.737, P<0.001). The top 10 death causes were lung cancer, liver cancer, colorectal cancer, esophagus cancer, gastric cancer, lymphoma, breast cancer, pancreatic cancer, ovarian cancer and nasopharynx cancer. In-patients with pancreatic cancer had the highest fatality rate (9.6%). There were different ranks of death causes in different sex groups and age groups. Conclusion: Prevention and control work of cancer should be enhanced not only for cancers with high incidence such as lung cancer, esophageal cancer but also for the cancers which have low incidence but high fatality rate, such as pancreatic cancer and gallbladder cancer, which would help to improve the survival rate and quality of life of cancer patients in the future.

소득수준이 높으면 이와 함께 사회 경제 문화적 기대수준도 함께 향상되는 것이 일반적이며, 산업안전에 대한 기대수준도 함께 높아질 것이다. 그러나 우리나라는 소득수준은 그동안 많이 향상되었으나, 산재사망률은 OECD국가 중 가장 높은 수준이며 산재사망이 지난 10여년간 전혀 줄어들고 있지 않고 있다. 본 연구는 우리나라의 소득수준 대비 산재사망률을 관련 국가들과 비교하고 그 차이점을 분석하여 근로자 중심의 산재예방 대책의 문제점을 파악하고 이에 대한 적절한 대책을 제시하는 것을 목적으로 하여 진행되었으며, 이를 위해 소득반영 산재사망지수를 제시하였다. 그 결과 우리나라의 경우 비교국가 중에 그 수치가 가장 높게 나타났으며, 그 원인에 대한 분석의 일환으로 산업재해에 대한 법집행실적에 대한 비교를 한 결과 위반 사업주에 대한 법집행에 중점을 두는 영국의 경우와는 달리 우리나라의 법집행 실적은 상대적으로 낮은 편으로 나타나 건설공사의 안전성 향상을 위해서는 향후 법집행 강화의 필요한 것으로 나타났다.

The accident fatality rate has decreased by more than 90% compared to 2006, due to the safety management and safety investment based on the Rail Safety Act. Most railway safety indicators, including fatality rates, have improved significantly from 60% to 80%, reaching the level of developed countries in terms of most railway safety indicators. However, the only staff fatality rate at work is not improved, and it is 3 to 5 times higher than that of developed countries. Most of the fatality occurred during employee's work recently occurred due to accidents hit by train while track work. In principle, when operating track need to check or maintenance, the operation of the train should be stopped and the work carried out. However, in Korea, due to the highest passenger density and train operating density in the world, it is caused by a structural problem that requires workers to enter the track while the train is running and perform various tasks such as maintenance and inspection. In this study, we analyzed the risk of accidents caused by hit by trains on the track, which is the biggest cause of staff fatality, using the main statistics of the last 10 years. In detail, the scenarios of the main causes of hit by trains and workers were formed to suggest the effectiveness of the current preventive measures and supplementary.
