As a result of the enforced control of emission, many devices, including the diesel particulate filter, have been installed in diesel cars to reduce the emission of particulate matters. In this study, a car fire case has been investigated and analyzed. A car fire broke out after the vehicle traveled a distance of 1.4 km from a car service center. The car was provided with DPF cleaning when the DPF warning light came on. After being dismantled in the engine room, the car's engine and gearbox were investigated. The findings showed that the rear part of the DPF metal case was melted and punctured, while the honeycomb filter of the DPF was damaged. The car fire was caused by an overheated DPF associated with inaccurate maintenance practice. Therefore, the responsibility of the fire rested on the car service center that performed the DPF cleaning.

Although it is widely accepted that a fire can occur due to electrical causes even when an engine stops, there is little introduction of detailed case analysis. This study analyzed a fire case caused by an electrical cause during engine stopping at parking lot in detail. Moreover, it was revealed that the fire was mainly caused by design defect.

It is often thought that because no-start motor vehicles cannot start an engine, a fire cannot occur for motor vehicle causes. However, although the engine cannot start up, some parts may be live with electricity if a battery is connected. If the parts have problems, a fire can occur. This study analyzed the causes of fires occurring when a motor vehicle was loaded onto a tow truck to service no-start. It is suggested that no-start motor vehicles should separate a battery terminal to prevent a fire. And this fire is related to automotive products liability.

The purpose of the present research is to provide a plan for an effective evacuation of residents and people who's in need of evacuation (such as children, the handicapped, and the old) and for the situation when staircase is not available for evacuation, by means of analyzing the evacuation behavioral characteristics of the residents or the evacuators and suggesting an evacuation plan using an emergency elevator in order to minimize casualties in case when fire broke out in a skyscraper.

This study analyzed the cause and liability of a car fire. The car was purchased 1 year ago and had traveled 8,500 km. When the car stopped at a red right and was about to start when the light turned green, the car next to it sounded itsa horn. As a result, the driver stopped the car and found that there was a fire in the engine compartment, which the fire brigade subsequently extinguished. This car fire may have been caused by an electrical spark from a screw hook inserted into the battery + terminal. Therefore, the courts decided that the car owner or driver was not responsible for the fire, because the electrical spark from the hook that caused it resulted from the automaker's manufacturing defect.

A society will lose a lot of something in this field when the forest fire broke out. If a forest fire can be detected in advance, damage caused by the spread of forest fires can be prevented early. So, we studied how to detect forest fires using CCTV currently installed. In this paper, we present a deep learning-based model through efficient image data construction for monitoring forest fire smoke, which is unstructured data, based on the deep learning model YOLOv5. Through this study, we conducted a study to accurately detect forest fire smoke, one of the amorphous objects of various forms, in YOLOv5. In this paper, we introduce a method of self-learning by producing insufficient data on its own to increase accuracy for unstructured object recognition. The method presented in this paper constructs a dataset with a fixed labelling position for images containing objects that can be extracted from the original image, through the original image and a model that learned from it. In addition, by training the deep learning model, the performance(mAP) was improved, and the errors occurred by detecting objects other than the learning object were reduced, compared to the model in which only the original image was learned.

Recently heavy traffic is getting worse because increasing population of transportation in urban area. In order to solve this problem. subway is realized with high speed, high density, highly efficiency. When fire accident happened in Dae-Gu subway in February 2003, there happened loss of people and lots of damage because of not being able to control even though fire alarm which was set up in the station rang. This thesis has constructed a simulation integrating operation system using a Database construction, operating program analysis in order to build up the most efficient train operation system. The result of simulation integrating operation system with emergency virtual situation like station and train fire, train failure, power line failure, all trains running on the rail were secured safety by train operation control system. With integrating operation of each train control system, train system, power system, machine facility system, the most efficient integrating operation system should have been constructed at the time the subway fire and power failure broke out.
