Traffic accident by aging drivers is expected to be on the rise rapidly as the number of aging drivers is rising along with the aging trend being progressed. In this study, traffic accident features depending on the classification of aging population and non aging one was evaluated. As a result of this evaluation, effect factors influencing over the aging population was found to be expressed differently from that of the non aging one. Odds ratio between the aging population and non aging one was evaluated through logit model and a model with potential accident probability of the aged drivers was developed. Accident risk of the aged drivers under the condition of curved road, cutting section and moistured road was revealed to be higher than that of the non aging population.

This paper is an attempt to examine historical drama which change rapidly in the manner of seeing history. Historical records are treated differently unlike in the field of modern history. Now the distinction between historical facts and fictions becomes no longer important. This change is affected by micro history, new cultural history, or post-modern history. History and narrative become interactive each other. In this respect they are no more historical drama. by Han Areum (director Suh Jae-hyung) represents this new trends. Of course, it doesn't suddenly pop up in 2005. It began in by Lee Yoon-Taek, was reinforced in by Kim Tae-Woong, and bloomed in . I intended to search important features of by following three. First is the interest about unimportant persons such as a maid of honor, an eunuch. In , they are the main characters. The author described much about those trivial people revealing the truth in different way of the existence. Second is the way of calling a past. In this piece, the past is not continuous. The past always appears at the stage by the present in the form of split which is imagination, recollection, revival. Third is a mixing genre. Comics, melodrama, and thrillers are all together in . This is a similar phenomenon to historical novel and movie of new trend. Strictly speaking, this piece isn't a history thriller. The accident of lost prince doesn't be treated importantly and the result isn't clear either. In this piece, detective genre is used for a symbol showing that writer pursuits the history, not the event. This represents well the characters of new historical drama because how historical facts are carefully recreated and constructed are important. It's enough to show the possibility to mix genre through comics and melodrama.

With Zohar(1980)'s research on safety climate and industrial safety, occupational safety and health literatures begin to emphasize the influence of organizational context. Based on this research trend, this paper tried to review the relationship between individual/ organizational factors and occupational accidents. Based on the responses from 294 manufacturing workers, this paper reviewed the relationships among safety climates, safety performance, and age. The results of statistical analysis showed that all safety climate factors have affirmative effects on safety participation and safety attitudes negative effect on accident number, and job load affirmative effect on accident number. Job load and management commitment showed interactive effects on accident number with age.

Recently, in the whole fields of industry including shipping business, the conception and importance of Human Factor is very highly and frequently emphasized. But the domestic crew disaster including injury and illness in our shipping business shows higher accident rate than other shipping countries. Therefore the developing of measures to prevent/reduce the accident is highly required as the marine accident including crew disaster causes enormous loss of property and human life in size and scale. But, because the domestic data regarding the crew accident are relatively insufficient and rule, the developing of those measures has many difficulties. Therefore, this study is to make the concerning data for the useful reference by showing the trend and current situation of crew accidents, assorted by the crew's rank, type of the accident, injured part of the body, cause of the accident, type of ships and type of the works when the accident occurred, by using the each ocean-going shipping company's recent 5 years('95∼'99) data in korea.

In this study, It is focused on development of the forecasting model about trumpet InterChange(IC) ramp accident because of the frequency of accident in ramp more than highway basic section and trend the increasing accident in ramp. The independent variables was selected through statistical analysis(correlation analysis, multi-collinearity etc) by ramp types(direct, semi-direct and loop). The independent variables and accident rate is non-linear relationship. So it made new variables by transformation of the independent variables. The forecasting models according to exit-ramp type (direct, semi-direct and loop) are built with statistical multi-variable regression using all possible regression method. And the forecasts of the models showed high accuracy statistically. It is expected that the developed models could be employed to design trumpet IC ramp more cost-efficiently and safely and to analyze the causes of traffic accidents happened on the IC ramp.

Recently, severe accidents in nuclear power plants (NPPs) have become a global concern. The aim of this paper is to predict the hydrogen buildup within containment resulting from severe accidents. The prediction was based on NPPs of an optimized power reactor 1,000. The increase in the hydrogen concentration in severe accidents is one of the major factors that threaten the integrity of the containment. A method using a fuzzy neural network (FNN) was applied to predict the hydrogen concentration in the containment. The FNN model was developed and verified based on simulation data acquired by simulating MAAP4 code for optimized power reactor 1,000. The FNN model is expected to assist operators to prevent a hydrogen explosion in severe accident situations and manage the accident properly because they are able to predict the changes in the trend of hydrogen concentration at the beginning of real accidents by using the developed FNN model.

There have been 1,039 accidents in laboratory(National Research Safety Headquarters). Accidents in laboratory has increased by 71.5% from 158 cases in 2011 to 271 cases in 2016. Accident analysis results show that there has been no death accident after 2011 when 5 death accidents happened. The results also show that severe injuries have been 23 cases(2%) from 2011 to 2016(7 cases in 2011, 2 cases in 2012, 2013 and 2014, 3 cases in 2015, 7 cases in 2016). Minor injuries shows increasing trend from 151 cases in 2011(92.6%) to 294 cases in 2016(97.6%). Among the causes of accidents in laboratory, piercing injuries by injector were 69 cases(10.4%) for recent 3 years, i.e. 22 cases(12.6%) in 2014, 18 cases(14.2%) in 2015 and 29 cases(16%). Piercing injuries by injector with infection such as viral hepatitis and HIV/AIDS were identified in 10 cases in 2014, 5 cases in 2015, and 10 cases in 2016.Therefore, we would like to contribute to the safety of laboratories by suggesting a guideline for prevention and post management of laboratory accidents.

Purpose: This paper investigates how companies respond to government regulations and disasters in a risk-managed society, and aims to initiate discussions on the future prospects and challenges. Specifically, it explores how companies can plan to respond to such disasters in the future, and stresses that the law should be to protect people's lives and ensure safety, rather than to punish companies. Research design, data and methodology: The study methodology is based on a review of existing literature, as well as trend analysis through big data analysis. The research analyzes the discourse in our society regarding the enactment of the Serious Accident Punishment Act. Results: This study supports that the Serious Accident Punishment Act should be implemented in a manner that does not impede corporate activities, but rather helps to ensure the safety of citizens' daily lives. The authors call for collaboration between communities, labor unions, and companies in achieving a cooperative governance system for a safer society. Conclusions: It highlights the importance of addressing disasters and government regulations in the context of a risk-managed society, and offers insights for both companies and policymakers on how to navigate these challenges. By prioritizing safety and cooperation, we can work towards building a safer and more resilient society

The construction accidents which had been on the downward trend for the past decades have increased for five consecutive years since 2008. In order to let the increasing trend of construction accident slow growing or switching to decline, various efforts are required of all members in construction industry such as government, employers, construction engineers, safety managers, construction workers, etc. Although the criteria for appointment of safety managers in construction site introduced in 1982 have contributed to prevent construction accident as a forefront for the past 30 years, it has not been a remarkable improvement in the safety manager's status and roles which have been required to change according to the changes of circumstances and environments. In associated with a newly introduced the criteria for appointment of health managers in construction site in the year 2015, the problems such as role, status, number of safety and health managers are needed to be considered comprehensively and improved widely. In this study, we propose several improvement plans which will improve the current criteria for appointment of safety and health managers in construction sites.

For a long time, research into integrated deterministic-probabilistic safety assessment has been continuously conducted to point out and overcome the limitations of classical ET (event tree)/FT (fault tree) based PSA (probabilistic safety assessment). The current paper also attempts to assert the reason why a technical transformation from classical PSA is necessary with a re-interpretation of the categories of risk. In this study, residual risk was classified into interpolating- and extrapolating-censored categories, which represent risks that are difficult to identify through an interpolation or extrapolation of representative scenarios due to potential nonlinearity between hardware and human behaviors intertwined in time and space. The authors hypothesize that such risk can be dealt with only if the classical ETs/FTs are freely relocated, entailing large-scale computation associated with physical models. The functional elements that are favorable to find residual risk were inferred from previous studies. The authors then introduce their under-development enabling techniques, namely DICE (Dynamic Integrated Consequence Evaluation) and DeBATE (Deep learning-Based Accident Trend Estimation). This work can be considered as a preliminary initiative to find the bridging points between deterministic and probabilistic assessments on the pillars of big data technology.
