Recently, a lot of accident report documents have accumulated in almost all of industries, including critical information of accidents. Accordingly, text data contained in accident report documents are considered useful information for understanding accident processes. However, there has been a lack of systematic approaches to analyzing accident report documents. In this respect, this paper aims at proposing text analytics approach to extracting critical information on accident processes. To be specific, major causes of the accident occurrence are classified based on text information contained in accident report documents by using both textmining and latent Dirichlet allocation (LDA) algorithms. The textmining algorithm is used to structure the document-term matrix and the LDA algorithm is applied to extract latent topics included in a lot of accident report documents. We extract ten topics of accidents as accident types and related keywords of accidents with respect to each accident type. The cause-and-effect diagram is then depicted as a tool for navigating processes of the accident occurrence by structuring causes extracted from LDA. Further, the trends of accidents are identified to explore patterns of accident occurrence in each of types. Three patterns of increasing to decreasing, decreasing to increasing, or only increasing are presented in the case of a chemical plant. The proposed approach helps safety managers systematically supervise the causes and processes of accidents through analysis of text information contained in accident report documents.

Traffic accident number is decreasing tendency every year. But, large size accident or hit-and-run case increases continuously. As well as, traffic accident causes real form of accident ambit thats why, social expense rises. For that reason we are going to present our plan that can prevent traffic accident when traffic accident occurs, we presented our idea that can arbitrate traffic accident quickly. Driver can know more correctly traffic circumstance through hearing and sight by using DMB. Finally, we suggested plan that supply traffic information that is more effective by TPEG.

Unlike in general manufacturing process, safety management in laboratory-based research area is complicated because the latter generally involves trying untested methods or handling unusual substances in small amounts. Laboratory accidents in South Korea have recently shown an increasing trend. Unfortunately, statistics on such accidents are not officially published by any domestic public agencies. In this study, multivariate analysis was performed on the relationships between variables to develop effective strategies for preventing laboratory accidents. A Cross-Tabulation Analysis of accident-related factors in 179 accident cases revealed that the laboratory type, accident type, and unsafe-act type are all statistically significant, whereas the unsafe condition and management factors differ with the statistical criteria. Furthermore, the results of a Multiple-Correspondence Analysis showed that accidents can be divided largely into three groups having different accident causes and injury types; this confirms the necessity of different strategies to prevent accidents of each type. The findings also reveal differences between the distribution of accident types mentioned in the accident case collection books and actual reported cases. This suggests that an official statistical system administered by a public institution would be necessary for effective prevention of laboratory accidents.

Five cases of traumatic diaphragmatic hernia were repaired in the Department of Thoracic Surgery, Seoul National University Hospital, during the period from 1967 to 1974. The first case, a 14-year aid girl, was diagnosed as diaphragmatic hernia during laparotomy because of jejunal perforation 3 days after traffic accident. Herniated stomach, transverse colon, spleen and left lobe of the liver were repositioned and the diaphragmatic rupture on left posterolateral portion was repaired with two layers of nonabsorbable sutures by transthoracic approach. The second case, a 26-year old man,was diagnosed immediately after traffic accident at a local clinic and transferred to this hospital 24 hours later. Herniated stomach, transverse colon and jejunum were repositioned amd diaphragmatic rupture,about 9 cm in length,from the posterolat.edge to the base of pericardium was sutured in two layers. The third case, a 26-year old man who had stab wound on the left lower lateral chest two years ago,was admitted with sudden abdominal pain and vomiting. Upper gastrointestinal series with barium meal revealed diaphragmatic hernia. The herniated stomach and transverse colon through the defect,about 3.5cm in diameter, at anterolateral portion on the left side,were repositioned and repaired with two layers of nonabsorbable sutures. The forth case, a 26-year old man, sustained blunt trauma to the chest by a roller and was transferred to the emergency room complaining of dyspnea 40 minutes after the accident. The diaphragmatic rupture extended from left midaxillary line to contralateral anterior axillary line,about 20cm long, at anterior portion of diaphragm, which was repaired with two layers, of nonabsorbable sutures. The fifth case, a 4-year old girl, had two separate diaphragmatic ruptures on both sides, which were caused by traffic accident. Immediate upper gastrointestinal series after injury showed herniated stomach, colon and spleen into left Chest cavity. Another small rupture with anterior edge of right lobe of the liver in chest cavity was noted. These were repaired with non-absorbable sutures via thoracotomy.

As the using rate of an explosive gas has been increased in the industrial site, the regional residents adjacent to the site as well as the site workers have frequently fallen into a dangerous situation. Damage caused by accident in the process using hydrogen gas is not confined only to the relevant process, but also is linked to a large scale of fire or explosion and it bring about heavy casualties. Therefore, personnel in charge should investigate the kinds and causes of the accident, forecast the scale of damage and also, shall establish and manage safety countermeasures. We, in Anti-Calamity Research Center, forecasted the scope of danger if break out a fire or/and explosion in hydrogen gas facilities of MLCC firing process. We selected piping leak accident, which is the most frequent accident case based on an actual analysis of accident data occurred. We select and apply piping leak accident which is the most frequent case based on an actual accident data as a model of damage forecasting scenario caused by accident. A jet fire breaks out if hydrogen gas leaks through pipe size of 10 mm ${\Phi}$ under pressure of 120 bar, and in case of $4kw/m^2$ of radiation level, the radiation heat can produce an effect on up to distance of maximum 12.45 meter. Herein, we are going to recommend safety security and countermeasures for improvement through forecasting of accident damages.

Conventionally, there were few cases in which a medical accident became a criminal case in Japan. However, after the serious malpractice such as the Yokohama City University Hospital case, prosecutors came to be less hesitant to prosecute a malpractice. In a medical accident, the attribution of the responsibilities among medical personnel becomes one important element of the proof of negligence. The Supreme Court concluded that, when the attribution of the responsibilities is not established among medical personnel to confirm the identity of the patient like the Yokohama City University Hospital case, all the personnel who were involved bear the responsibilities to identify the patient. For serious cases which requireut most carefulness fortreatment such as the Saitama Medical University Hospital case, not only the chief physician in charge of the case concerned but also the director of the branch at the university hospital bear the responsibilities to confirm the treatment policy of the case. After the acquittal of the Ohno Hospital case, the voice demanding more prudent prosecution of malpractices has become stronger than before. Meanwhile, Ministry of Health, Labour and Welfare introduced Medical Accidents Investigation System for the prevention of medical accident and, has reinforced the third party inspection of medical accidents.

The purpose of this study was to investigate the situation of occurrence of disease and accidence of child care center. The subjects of this study were 17 public district child care centers, but only one center kept their health diary. Therefore, it became finally the only subject for this study. The data were collected through the analysis it's health diary and case reports for emergency. The collected data were analyzed by the number of cases, age and sex, types of case, and the emergency case were analyzed by age, background, types of accidents and follow up. The number of cases of disease and accident in 2002 were 572. In sexual difference, boys more have accident than girls. The teachers and the outsiders also frequently use the health care service. Smallpox and epidemic conjunctivitis were spreaded during winter and summer. In causes of accidents, 'accident by other child' were 98%. In emergency cases, 1 pierced wound, 1 dislocation, 2 dental emergencies, 4 eyeball contusion and bleedings and 2 burns were occurred. all the cases of emergency were performed follow up education. On the basis of above data, there will be needed to intensify health and safety subjects in curriculum for the teacher of child care, and health and safety education for child. Each child care centers must have health care manager and the network for emergency. To enhance the quality of child care service, government have to offer financial and systematical support.

In an effort to enhance the independence of and expertise in military aircraft accident investigation, a permanent accident investigation board should be established. Establishing permanent accident investigation board would render the military accident investigation more reliable and would increase its public esteem. Because there is no provision governing the responsibilities of the investigation and cooperation between civil and military authority in case that both civil and military aircraft are involved, it is necessary to fill this gap by enacting appropriate laws. In case of civil aircraft accident investigation involving a military issue, it would be better to allow military authority to be involved in the investigation. For the betterment of investigation, it is also necessary to provide a field investigator an authority to directly collect relevant information. Since the sole purpose of accident investigation is to prevent the recurrence of aircraft accidents, the scope of information disclosure should be limited and the investigation report shall be used for neither criminal procedure nor disciplinary procedure so that the objectivity of the investigation should be ensured.
