The state and its proper countermeasures of unreported industrial accidents in Gyungbuk area was investigated throughout a survey research. The goal of the study was to identify major factors that affect the number and causes of unreported accidents. Results from the survey indicated that significant number of unreported accidents exists especially in the small and medium sized industries. Types of the accidents, amount of increase in the insurance cost and level of the governmental enforcement due to the accidents were the major factors for deciding whether to report or not. These results suggested more compromising actions have to be taken by the government for revealing the present but unreported industrial accidents. A more efficient way for preventing the industrial accidents can be considered on the basis of true understanding about real industrial accident statistics.

The total number of confined space accident cases from 1999 to 2007 in Korea were 220, causing 353 injuries and 212 casualties. Out of 220 cases, 44(20.0%) occurred in sewage treatment facilities and 40(18.2%) occurred in both manholes and containers. When the main causes of confined space accidents were classified, oxygen deficiency accounted for 69 cases(31.4%), carbon monoxide, 48(21.8%), hydrogen sulfide, 40(18.2%), and organic solvent, 32(14.5%). Improvement of occupational accident statistics is necessary in order to report accurate and precise data for confined space accidents. The structure of confined space must be considered when selecting gas to be measured.

This study aimed to compare fear and prevention behaviors on accidents between mothers and teachers in family childcare centers. The participants were 117 mothers whose children were 0~2 year-olds and 121 teachers. Based on Hendrickson(2008) and Reichert & Henricks(1996), the scale was developed by the researcher, and it was composed of fear and prevention behaviors on accident. The data were analyzed using descriptive statistics and $x^2$ analysis. Results showed that mothers feared fall accidents and step-on-accidents while teachers feared suffocation accidents and liability for injury medical fee. Also, mothers did more prevention behaviors on use of car seats than teachers, whereas teachers did more behaviors on walk safety, custody of drugs and dangerous articles, and food safety.

The systematic information management of chemical accidents is required as a tool for the policy making, system improvement and release of information. However, there isn't yet a systematic chemical accidents tracking system in Korea, which make a confusion that the related statistics are different from each others. In this research, we analyzed domestic and international chemical accidents data and made the chemical accident codes for the information tracking system properly.

Although the disaster rate of the industry as a whole is on a downward trend, the disaster rate of the construction industry is on an ongoing trend. Therefore, in this study, we analyzed safety accident statistical data of the construction site over the past three years. As a result of the analysis, the incidence of disasters at small construction sites was very high. And the proportion of disaster occurred for workers who worked in less than 6 months even roughly 92.6%. In addition, as a result of analyzing the form of disaster occurrence, the crash was 34.1% and the fall was 15.1%. The analysis results of these construction safety accidents are to provide as a basic material for developing a policy that can prevent safety accidents and a safety accident prediction model.

This study proposed a traffic accident prediction model developed based on administrative districts of Seoul. The model was to find the relationship between accident rates and the representative land usage of the districts (development density) - the higher the development density (building floor area) is, the higher the traffic accident rate is. The findings showed that traffic accident statistics differ from (1) residential building floor area, (2) commercial building floor area and (3) business building floor area.

Purpose: The primary objective of this research is to propose answers of rider's accident of food retailer in South Korea, in view of business sustainability of food retailer and his precious fate of rider who is a father that has a responsibility to the family. Research design, data, and methodology: We investigated previous studies such as food retailer, delivery, delivery application of mobile, rider's accident and statistics of delivery business agency, motorcycle accident ratio, annual fatalist, and further we analyzed cases of rider's accidents. Results: Rider's accident on the road toward food retailer is serious risky factor to their business reputation, corporate image, because claim amount related to death and physical/mental disability can be heavily damaged to food retailer. The point when rider dies is that rider is a person responsible for supporting his/her family, that is, a life itself issue together with downfall of family. Conclusions: In view of growth of South Korean' delivery rider industry, the authors recommended that focus of stability and sustainablity of both food retailer and delivery rider should establish to executable and practical ideas such as rider's readiness, abandon of speed guarantee, duty of delivery app business and legal aids.

This paper introduces how to adopt the concept of temporal hierarchies to forecast time series data. Similarly as in hierarchical cross-sectional data, temporal hierarchies can be constructed for any time series data by means of non-overlapping temporal aggregation. Reconciliation forecasts with temporal hierarchies result in more accurate and robust forecasts when compared with the independent base and bottom-up forecasts. As an empirical example, we forecast traffic accident counts with temporal hierarchies and observe that reconciliation forecasts are superior to the base and bottom-up forecasts in terms of forecast accuracy.

The paper introduces bottom-up and optimal combination methods that can analyze and forecast hierarchical time series. These methods allow forecasts at lower levels to be summed consistently to upper levels without any ad-hoc adjustment. They can also potentially improve forecast performance in comparison to independent forecasts. We forecast regional traffic accident counts as time series data in order to identify efficiency gains from hierarchical forecasting. We observe that bottom-up or optimal combination methods are superior to independent methods in terms of forecast accuracy.

Choosing automobile safety options is price-performance matter. The best fit options to buyer who has a certain driving habit are problem of MCDM (Multi Criteria Decision Making) because price of safety option, statistics of relating accident, consequence of accident, and driving habit are the multi criteria to be evaluated. In this paper, PROMETHEE-GAIA methodology is applied for solving this MCDM problem. The result shows that a different driving habit makes different choosing priority of safety options.
