The purposes of fire investigation are to identify and analyze the causes of fire and, using the results in promoting fire fighting policies, ultimately to prevent fires caused by similar causes and to protect people's life and properties from fire. However, although the patterns of fire are getting more diverse and complicated with the rapid development of industry, complicated with the rapid development of industry, fire fighting organizations are continuing traditional superficial fire investigation without operating a fire investigation department for the reason of insufficient manpower, equipment and budget, losing public confidence. Thus, the present study purposed to propose plans to improve the technicality of fire investigation and win public confidence in fire investigation. First, the technicality of fire investigation should be improved by operating a department and personnel exclusively for fire investigation. Second, fire investigation should be more scientific and precise using high tech fire investigation equipment. Lastly, responsible fire fighting administration should be realized through statistical analysis of the causes of fire and computerization. The results of this study are expected to contribute to the safety and security of our society.

There are continuous cases of fire expansion due to fire door problems around the world, including the 2010 Shanghai Apartment Fire, the 2017 Grenfell Tower Fire in England, and the 2020 Ul-san Residential and Commercial Complex Fire. In order to prevent such fire damage, the country has strengthened the performance standards of fire doors, and recently, efforts have been made to ensure the best performance of fire doors by introducing a quality recognition system. Securing the performance of fire doors is a very important aspect. However, there is a concern that old fire doors may not function normally in the event of fire due to natural deterioration, corrosion, and damage during the use process, but countermeasures are insufficient. Therefore, from a management perspective, it is very important to maintain fire doors and secure an appropriate replacement time. Therefore, the purpose of this study is to determine whether the fire door has durability to prevent fire spread in the process of use through operation probability analysis and expert surveys, and to propose an appropriate useful life of the fire door.

The origin of "Fire" in Traditional Chinese Medicine is summed up based on observation and knowledge of natural fire, followed by abstract thinking, of which the outcomes are best symbolized in the character Fire[火]. Because it is an abstract concept, it is hard to give a single and strict definition. Naturally, it would be necessary to analyze and illustrate the origin of 'Fire' from different angles such as broad definition, multi-definition, levels, classifications and effects. The concept of 'Fire' has four meanings in the aspect of the broad definition: first, natural fire; second, the physiological conception of fire; third, the medical conception of fire; fourth, general concept related to fire. In Traditional Chinese Medicine, fire mainly indicates physiologic fire, pathological fire, the fire in the six kinds of natural climate and the fire as one of the properties and the flavors of herbs.

This study presents an analysis of comparison of P-type fire detection system with fuzzy logic-applied fire detection system. The fuzzy logic-applied fire detection system has input variables obtained by fire experiment of small scale with K-type temperature sensor and optical smoke sensor. And the antecedent part of fuzzy rules consists of temperature and smoke density, and the consequent part consists of fire probability. Also triangular fuzzy membership function is used for input variables and fuzzy rules. To calculate the final fire probability a centroid method is introduced. A fire experiment is conducted with controlling wood crib layer, cigarette to simulate actual fire and false alarm situation. The results show that peak fire probability is 25[%] for non-fire and is more than 80[%] for fire situation, respectively. The fuzzy logic-applied fire detection system suggested here is able to distinguish fire situation and non-fire situation very precisely.

Today, the basic problem of functional safe management of Korean Disaster Control system was separately administrated 33 acts that are relating to safe management in 13 ministries. Because of the facts that the fire service is not provided practically, the control system and risk management for safe administration are not operated, the information can not be shared with each other, and the various laws have the lacks of linkage, the National Safe System was appeared unsteady. The roles and functions of fire service have started with restriction to operate structurally and institutionally, which operational structure of fire service is becoming weak. As a result, the federal and local fire organizations have not reached yet to the institutionalization and the local fire service agencies have bias with the task regarding the fire service because of the relation between organizational structure and the local fire agency. With the enforcement of the federal and local fire system, professionality and autonomy for making policy, and dealing with changes of fire service positively, the national fire service on the policy performance can be established. Promotion of research and development and education training to strengthen innovation in technology and competition in fire industry will contribute to the firmly establishment of control system to prevent from fire, flood, terror and national disaster. This article proposed that (a) the established law and administration, agency are required efforts to effectively operate fire service system; (b) the national fire service agency, national college of fire, national institute of science fire, and national fire service hospital should be early established to make firmly policy to operate effectively and practically. These kinds of innovational acts are known the best ways of operating solid policy of national fire service system.

Fire investigation to examine ignition and combustion enlargement etc., to assess fire damage and to investigate a fire suspect, is used as a valuable data for better fire suppression and fire prevention police. Fire investigation is divided in to fire-cause investigation, fire-damage investigation, and fire-criminal investigation. At present, fire-cause investigation is lacking In scientific technology; specially is deficient in accurate damage assessment. And considering fore criminal investigation, since the police lacking in specialty on fire take exclusive charge of fire criminal investigation upon general investigation, it is difficult to investigate fire criminal effectively. Finally deficiency in fire investigation operates as very big blind-spot in fire safety having important axis in social safely; the loss is shifted on nation's shoulder. To solve those problems, legal, institutional, operational preparation is urgent. And so, this study tried to stabilize specialty of fire-fighting to offer more active, qualitative fire administration service, and to contribute to public peace and welfare by grasping problems after diagnosing Korean fire investigation and proposing the solutions.

The rapid progress toward the 4th industrial society has led to possibilities of fire increase. It is pointed out that, though initial fire suppression is emphasized, the current legal systems do not sufficiently recognize the importance of initial fire suppression. In order to resolve this, problems of the current legal systems and regulations, as well as fire-fighting facilities to be equipped according to the size of specific fire-fighting objects, were diagnosed. Also, suggestions for improvement were provided through comparative analysis with relevant laws and technical regulations of Korea and other countries. According to fire safety standards such as NFPA, IMO, ISO, and Russian standards, automatic fire extinguishers are to be installed as per the adaptability criteria of fire extinguishers and automatic fire extinguishers. In Korea, the "Act on Fire Prevention and Installation, Maintenance, and Safety Control of Fire-fighting Systems" cover the types and scope of fire fighting facilities that include specific fire protection objects, such as electric room, power room, and substation room. This study has identified that, in case of a place with a floor area of less than $300m^2$, the installation requirement is not clearly specified. Therefore, in this study, fire extinguishing equipment and automatic fire extinguishing equipment to be added for each sub-use application are proved to have fire extinguishing performance of Class A, Class B, and Class C, respectively. In view of the fact that, in overseas standards, all space except containing such materials as Deep fire, metal fire and peroxide, can be installed with fire fighting equipment, a legal system for specifying the capacity units of fire fighting apparatus by application is, in this study, proposed.

It was described the measured friction loss depending on pressure used and changes in water flow rates for a fire hose used at a fire scene on this study. As a result of actual measurement based on the result obtained by analyzing the use situation of a fire hose such as the kind, quantity, pressure used, etc. of a fire hose, the friction loss in a fire hose under the condition of using by a fire officer at a fire scene was measured as up to 56.8 %. This is much different from the equivalent length of a fire hose used to calculate the pump head in an indoor and outdoor fire-fighting facility. There is no related restrictive regulation on friction loss, there are even no data on friction loss measured by fire hose makers, and spreading a fire hose without considering friction loss at a fire scene can result in an increased length of hose used and a high-pressure water discharge from a fire engine, so this study aims to establish a standard for an equivalent length to friction loss in a fire hose and to propose a spreading method considering friction loss in a fire hose at a fire scene.

Objective : The concept of Eum-Fire(陰火), which was brought up by Li Dong-yuan(李東垣), is such a very ambiguous thing that many medical scholars had tried to understand its real meaning. Trying to understand the real concept of Eum-Fire, this study goes on based on the view that the concept of Eum-Fire in the medical books of Li Dong-yuan was used as being the same thing with the concept of Xim-Fire(心火) and Premier-Fire (相火), and the substance of this kind of fire is the fire in Ximpo(心包) and Myungmun (命門) which works in the system of Ximgye(心系). To verify this view is the main objective of this study. Method : Inquiring into Li Dong-yuan's medical books, this study investigated examples of the uses of the terms of Eum-Fire, Xim-Fire and Premier-Fire, and analyzed the relation between the meanings of these terms. And as a collateral evidence to the main view of this study, this study notes Wang An-dao(王安道)'s reference about Eum-Fire and inquires into the concept of Premier-Fire that was formed by Liu He-jian(劉河間), who had been referred to in Wang An-dao's argument about Eum-Fire. And this study also presents the Chen Shi-duo(陳士鐸)'s view about Eum-Fire that is expected to show a more concrete concept of Eum-Fire than now and seems to deserve to be compared with that of Li Dong-yuan. Result and Conclusion : It could be understood that the concept of Eum-Fire in Li Dong-yuan's books was used as a thing that owns the same substance as a kind of fire with Xim-Fire and Premier-Fire. In this viewpoint it could also be understood that Li Dong-yuan had attached the concepts like Xim-Fire and Eum-Fire to the concept of Premier-Fire, so terms like these could be understood as such concepts that represented the diverse figures of Premier-Fire. And this study also found that the substance of Xim-Fire as a kind of Premier-Fire means the fire of Ximpo and Myungmun that works in the system of Ximgye, which seems to be formerly introduced as a frame of Premier-Fire by Liu He-jian. This study also found the indirect basis of this viewpoint in the books of Chen Shi-duo, and could get a conclusion that Chen Shi-duo's view about Eum-Fire can be regarded as a thing that could show us more concrete matter of Eum-Fire than now.

Wooden cultural heritages have many factors of fires and structural characteristics vulnerable to the fire extinguishing. Also, they are surrounded with forests and so remote from fire stations, which make it difficult to handle it quickly when fires break out. Wooden cultural heritages made of wood materials belong to the general fire in a Class A. Taking characteristics such as a smoldering and a backfire from the that fire of wooden materials into consideration, extinguishing the fire by the cooling system is the most effective. If the fire can't be put out at the early stage, it is almost impossible to protect wooden cultural heritages from the fire, because wooden structures can be destroyed in a high temperature and in a short time and it takes around average 7 minutes to reach its peak of flames in the process of a fire. According to the geographical and environmental situation of the cultural heritages, currently, the fire-prevention facilities such as the auto fire detector for the prompt detection, the water mist fire suppression system for the 1st early and urgent fire suppression and the outdoor fire hydrant and the water curtain etc. for the 2nd full-scale suppression and the prevention of the fire gaining force are being installed for the wooden cultural heritages.
