The realistic cases causing severe core damage should be analyzed and arranged systematically for preparing an accident management of the specific nuclear power plant. The objective of this paper is to establish basic technical information for reactor safety and reactor building integrity management strategies in CANDU reactor severe accident. For the development of severe accident management strategies, plant specific features and behaviors must be studied by detailed analysis works. This analysis scope will serve to cover overall methods and analyzing results to understand the reactor building integrity status in the most likely severe accident sequences that could occur at CANDU reactor. Also analysis results could help prevent or mitigate severe accidents for the identification of any plant specific vulnerabilities to severe accidents using the probabilistic safety assessment (PSA) quantified results.

Currently, as construction projects in Korea are becoming larger and more complex, the hazard rate of the construction industry is steadily increasing, contrary to other industries. This can be seen as an indication that the safety technology and safety consciousness of construction workers are insufficient compared to the improved construction technology. In addition, due to the characteristics of the construction industry based on manpower, most accidents appear in conventional forms such as fall and trip due to human errors. Therefore, analyzing the relationship between the characteristics of human resources and accidents and establishing detailed safety plans is an essential part of reducing construction accidents. In this study, a correlation analysis was conducted using 62,805 cases of construction accident cases over 3 years to derive the characteristics of accident occurrence focusing on the age of workers. As a result of the analysis, the relationship between the age of workers and the frequency and severity of accidents for each accident type was derived, focusing on the top 10 accident types.

This paper suggests to standardize railway accident restoration types as the standardized code and to develop standard operation procedures(SOP) for the efficient railway accident management and recovery system. First of all, occurred damage types as the existing railway accident types in both domestic and foreign cases have been carefully analyzed and then reclassified. Therefore, this study suggested the combination of 3 distinct code factors: restoration class, restoration object, and restoration location to standardize them. In addition, temporary restoration SOP will play a major role in the railway accident database management system and SOP for the damage limitation and the prevention of accident spread.

Whenever the accidents occur in the rail way areas, their prompt recovery is very important. The individual way has been used to resolve these accident by direct visiting the site and reporting to others of the person who cares for these cases. As a result, we are planing to operate the MTS (Multimedia Transmission System) for a timely information's transmission to the related peoples in the central control center by transforming the picture information on the accident-site to the digital information.

With the increase of population, dramatic urbanization, traffic, leisure and sports, the number of maxillofacial injury has increased markedly. Subsequently the number of motor vehicle accident, sports accident and industrial accident were increased and the number of oral and maxillofacial trauma patients were also markedly increased. A clinical study on 177 patients with facial bone fracture who visited Kangnam General Hospital during 4 years(1992-1995) was done by analysing sex, cause, fracture site, treatment method, complication and involvement of other body part. The results obtained were as follows : 1. The occurrence was more frequent in male than in female with the ratio of 4.2 : 1 and most frequently in twenties. 2. Violence was the most common cause of facial bone fracture. 3. Mandible was the most frequently occurred site and there were more cases of simple fracture(81.9%) than cases of compound fracture. 4. Simple fracture was most frequently occurred(44.0%). 5. In mandible fracture, simple fracture was 86.1%, fracture site was average 1.5 sites, most frequently in symphysis. 6. As treatment methods, open reduction(78.5%) was used more frequently than closed reduction(21.5%). 7. Post-operative complication occurred in 29.4% of the cases. 8. Other injuries that were related to maxillofacial fracture occurred in 28.2%.

Purpose - This thesis is to develop a management plan and checklist by analyzing the prevention of accidents in advance by presenting the management plan for the major causes of railway accidents. Research design, data and methodology - In recent 5 years, we have analyzed the cases of railway accident, presented the management plan for the accident, and made a practical safety checklist focusing on the main measures according to the management plan. Results - The analysis of the cases of near-railway accidents suggests more concrete and practical safety management measures because the similar accidents are continuously occurring due to formal safety management. Conclusions - It is more valuable to apply to the adjacent construction of the railway line by creating a detailed checklist based on cases rather than the existing checklist. This study is written only as a human factor. For future real - time safety management, it is necessary to study more precisely cause analysis and safety equipment as a big data - based safety control system for more systematic safety management.

It is difficult to predict industrial accidents in the construction industry because many accident factors, such as human-related factors and environment-related factors, affect the accidents. Many studies have analyzed the severity of injuries and types of accidents; however, there were few studies on the prediction of injured body parts. This study aims to develop a classification model to predict the part of the injured body based on accident-related factors. Construction accident cases from June 2018 to July 2021 provided by the Korea Construction Safety Management Integrated Information were collected through web crawling and then preprocessed. A naïve Bayes classifier, one of the supervised learning algorithms, was employed to construct a classification model of the injured body part, which has four categories: 1) torso, 2) upper extremity, 3) head, and 4) lower extremity. The predictor variables are accident type, type of work, facility type, injury source, and activity type. As a result, the average accuracy for each injured body part was 50.4%. The accuracy of the upper extremity and lower extremity was relatively higher than the cases of the torso and head. Unlike the other classifications, such as spam mail filtering, a naïve Bayes classifier does not provide a good classification performance in construction accidents. The reasons are discussed in the study. Based on the results of this study, more detailed guidelines for construction safety management can be provided, which help establish safety measures at the construction site.

Objectives: To investigate whether medical institutions can prevent accidents by analyzing the root cause of a medical accident and identifying the tendencies. Methods: A total of 345 medical cases were used for the RCA(Root Cause Analysis). The root causes were classified using the SHELL model. The suitability of the model was confirmed by SPSS's MDPREF and Euclidean distance. An SPSS20.0 hierarchical regression analysis was used as an influencing factor on the degree of injury resulting from medical accidents. Results: The SHELL model was suitable for classification. The rates of accident causes were LS49%, L34%, LL10.2%, LE3.7%, LH2.3%. The order in which the degree of a patient's injury was affected were: Risk Threshold (${\beta}=.180$), Time (${\beta}=.175$), Surgical stage (${\beta}=-.166$), Do not use procedure (${\beta}=.147$). Conclusions: Health care institutions should remove priorities through system improvement and training. For patients' safety, the five factors of the SHELL model should be managed in harmony.

This study reported on the cases about gender inequality in agriculture. Generally women have experienced something in vague situation as unequal to men in rural and agriculture. Despite of some women's have been complaining about this problem, it is not easy why and how many times they have been suffering. In this report, to get the information of gender unequality in agricultural laws and policies, the data was gathered by two steps. The first step, 175 cases into nine types was collected from leaders of several women farmer's associations, and after that, 60 cases selected to be interviewed by a specialist panel. The second step, it was analyzed the interviewed 60 cases based on real conditions compared with laws of items of policies. Among the cases, it was analyzed 8 rural women's who had been experienced to receive the inappropriate compensation in an unexpected accidents. From these cases, it was drew up some suggestions as follows; to make a rule to certify of the identity of woman farmer, and to build in a monitoring system of gender equality in agriculture.
