${\ulcorner}Volume\;1{\lrcorner}$ of ${\ulcorner}$Medical Records as a Guide to Clinical Works${\lrcorner}$, written by Ye Tian Shi, showed some clinical cases of dizziness. In this study, his diagnosis and treatment was studied with 16 clinical cases of dizziness with pathogenic factor, pathogenesis and symptoms of dizziness. Ye Tian Shi thought that phlegm, fire, wind and insufficiency were the causes of dizziness and phlegm-fire, phlegm-fire-wind, wind-phlegm and insufficiencyfire-wind were the causes of dizziness, clinically. Dizziness is caused when the body is in condition of excess in the upper and deciency in the lower. The acompanying clinical symptoms of dizziness are endogenous wind, fire of deficiency type, phlegm wind and phelegm fire. For the treatment of dizziness, Ye Tian Shi used the combination of medicines with some modifications by the cases for phlegm, fire, wind and insufficiency. He also encouraged the mental therapy for the treatment of dizziness. He emphasized the early treatment of dizziness to prevent hemiplegia after apoplexy. It can be postulated from Volume 1 of ${\ulcorner}$Medical Records as a Guide to Clinical Works${\lrcorner}$, diagnosis and treatment of symptoms and illness of Ye Tian Shi was strictly based on actual clinical cases.

This study examined cases of duplication and confliction of legislation related to fire safety in long-term care facilities. In addition, the aim was to provide implications about those cases in the perspectives of welfare for the aged. In relation to fire protection facilities, long-term care facilities are regulated by the Building Act and Fire Protection Act. Among those Acts, certain gaps, and conflicts by duplicated regulations were found. Although the related-acts have improved gradually, unsolved issues and retroactive applications still remained. The problems stated above were defined by reviewing specific cases and legal improvements in the perspectives of welfare for the aged were suggested.

As lithium batteries have been used for car navigation systems and as the second battery for black boxes, lithium battery-related car fires have often occurred. In the case a lithium battery is the fire origin, a fire investigation technique has not been established to determine if a battery ignites or whether the lithium battery is damaged by fire. This study introduced car fire cases related to lithium batteries, analyzed the causes of a fire of a lithium battery, and proposed fire investigation techniques to objectively determine if a lithium battery ignites or whether a lithium battery is damaged by fire after external ignition.

Since Daegu subway arson fire disaster in 2003, there have been several copycat crimes such as at Seoul Metro line number seven and Hongkong Chuiwan line cases. Oil and gas were used for fire propagation in most cases as in Daegu case and such fire could be expanded to a whole subway cabin within several minutes. The fire may eventually cause the whole subway system stop. Fire damage can be minimized when fire occurrence and diffusion are blocked by stages or isolated rapidly. This study suggests an effective early response system that separates passengers from fire and a real-time fire extinguishment program by stages. Based on the subway arson case studies, the early response scenario has been structured by three stages, i.e., confirmation of fire and damage, early fire extinguishment, and information dissemination and passengers evacuation.

This study analyzed recent cases of ship fires explosions and investigated their problems and coping plans. Through analysis on the statistical figures, it was found that our nation's situations of maritime accidents by kind during the period of 2009~2013 showed the ratios of ship accidents caused by fires explosions was the highest in 2012 with 7.58% (55 cases) followed by year 2009 with 3.39% (34 cases), year 2010 with 3.39% (25 cases), year 2011 with 6.03% (57 cases) and year 2013 with 6.74% (43 cases), which indicates a steady increase in the number of ship accidents. Majority of reasons for ship fires explosions were lack of safety awareness. Since those accidents happen on the sea, fires, once they happen, tend to get serious due to absence of on board & nearby fire extinguishing facilities, public fire service's uneasy access to them and great influences of natural factors such as wind and etc. Ship fires explosions are special cases unlike what happens to general edifices. So, their coping plans should focus on preventive measures since the damages those cases bring about can be detrimental. For this reason, it's necessary to research precise evacuation plans, develop ship structure & materials reinforcing fire resistance to secure more time for evacuation and enhance people's safety awareness by implementing thorough safety training.

Recently, the number of cases of fire spreading due to exterior materials of buildings is increasing. Due to the nature of modern architecture, which emphasizes the aesthetics of buildings, because buildings pursue a splendid appearance, they are inexpensive and have relatively good insulation performance, but an increasing number of buildings are adopting insulation materials that have poor fire safety performance. The risk of spread is also greatly increased. Since the exterior wall of a building is made of a variety of materials and structures, it is composed of a combination of several elements, including materials such as insulation and finishing materials. Therefore, it was determined that it was necessary to introduce a more systematic evaluation method for building exterior materials, and to improve the system reflecting this, away from the existing evaluation method that only checked the fire safety performance of finishing materials.

In order to find out the environment vulnerable to cigarette fire in which smoldering fire grows into flame fire, a cigarette combustion test and numerical analysis were performed using fallen leaves of P. densiflora and Q. variabilis. Tests were repeated five times on 2,304 conditions with four cases of fuel moisture content, six cases of velocity, two cases of cigaret location against direction of the wind, three cases of cigaret location against fallen leaves, two species of thickness of cigaret, two cases of slope conditions and two cases of fragileness of fallen leaves. Cigaret fire's flammability to the fallen leaves was monitored by analyzing heat transfer process using CFD (Computational Fluid Dynamic) under the most optimal condition through an ignition test on 2,304 conditions. The result of a cigaret fire ignition test for fallen leaves, found ignition in 197 conditions out of 2,304 conditions representing 8.6% while 13 conditions representing approximately 0.6% saw ignition across five repeated tests. The result of CFD analysis, the temperature of the bottom of fallen leaves was reached on self-ignition and pilot-ignition temperature.

Fire and smoke can from a small ignition source develop rapidly. Active systems in combination with Passive Fire Protection measures will offer highest safety standards to the building's developers and occupants. Nevertheless, the fire growth is very unpredictable and it is therefore essential at the planning stage that tested solutions are well selected according to National codes and later on installed by qualified contractors to ensure optimum performance. This demonstrates that Passive Fire Protection as safety measure cannot be neglected. Recent fire cases all over the world still proof that fire can develop any time and any where even in countries of high safety standards.

On the construction site, there exists frequently a high likelihood that a fire accident can lead to a large-scale disaster. In the previous studies, the diverse outcomes have been focused on the improvement of relative statutes and tried to realize the suppression and confrontation of the fire accidents. In this study, the limitations on the site were identified through prior research reviews, and the fire risk assessment checklist was proposed through the analysis of the massive accident cases. The checklist was divided into the prevention and minimization steps and developed into 16 categories of total risk factors. According to the results from the cases applied in this study, if the installation status is checked, such as removing combustibles, and broadcasting facilities for evacuation are installed, it is expected that the casualties will be minimized or zeroed. By developing a fire risk assessment checklist, this study provides the implications of the theoretical and realistic fire accident prevention, and supports the ways to minimize the damage resulted from the fire accidents on construction sites. In the further, deriving universe and common items about repeated occurrences of a work type will be needed as a subsequent research.

Diesel cars employ a diesel particulate filter (DPF) to reduce the discharge of fine dust. However, cases of fires caused by DPFs have been reported in diesel cars. In this study, I examined the regulation of exhaust gas and exhaust gas recirculation in diesel cars. Then, I analyzed cases of car fires caused by DPFs, their characteristics, car fire factors related to DPFs and preventive measures, and their consideration in investigations of the causes of fires. Finally, regarding car fire investigations, this study proposed a process of proving that fires are caused by DPFs.
