  • 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.

  • This paper presents an intelligent computer system, which can easily diagnose electrical fire causes, without the help of human experts of electrical fires diagnosis. For this system, a database is built with facts and rules driven from real electrical fires, and an intellectual database system which even a beginner can diagnose fire causes has been developed, named as an Electrical Fire Causes Diagnosis System : EFCDS. The database system has adopted, as an inference engine, a mixed reasoning approach which is constituted with the rule-based reasoning and the case-based reasoning. The system for a reasoning model was implemented using Delphi 3, one of program development tools, and Paradox is used as a database building tool. To verify effectiveness and performance of this newly developed diagnosis system, several simulated fire examples were tested and the causes of fire examples were detected effectively by this system. Additional researches will be needed to decide the minimal significant level of the solution and the weighting level of important factors.

  • Currently, safety management is becoming important at domestic construction sites. Despite the importance of safety management, accidents at construction sites are steadily increasing. Fire accidents among safety accidents cause not only negative effects on schedule delay or work plans at construction sites, but also huge casualties. Therefore, the purpose of this research is to extract the causes of fire at the construction site through the case of fire at the construction site, and to prioritize prevention through the analysis of the factors to contribute to the prevention of fire. As a research method, we select fire factors through case, conduct surveys through expert group, and analyze survey through AHP technique. The results of the AHP analysis of the survey of expert groups showed that the workers and their sub-item ranked high. Therefore, the priority for fire prevention was given, and this research is believed to help prevent fire.

  • This study examined the safety of storage tanks by analyzing the causes of fire on outdoor storage tanks. The outdoor storage tank is a fixed device for the long-term storage of dangerous goods and consists of a tank body and accessories; the accessories consist of a vent system, breather valve, flame arrestor, etc. The flame arrestor is a necessary safety measure to prevent fire explosions on outdoor storage tanks. On the other hand, it has been suggested that the installation of a flame arrester is necessary to compare the domestic and international standards. In addition, the flame arrester should be installed in the existing outdoor storage tanks, to complement foreign standards because there are not enough domestic standards to verify the performance of the flame arrester.

  • As the spread of DC power distribution systems increases, the occurrence of failures and fire accidents are also increasing. In particular, the ESS fire accident, which is a component of the smart grid, and the fire accident of the solar power system, which is a direct current system, are caused by problems in the electrical connection between system components as the supply of new and renewable energy rapidly increases and old facilities increase. An arc that can cause a direct fire by releasing the induced light and heat has been pointed out as one of the causes of fire. Therefore, the problem of such an arc defect is that it is impossible to block an arc accident in advance with the existing overcurrent circuit breaker and earth leakage circuit breaker. In this paper, we intend to develop a test equipment that satisfies international standardization and to develop a DC arc generator to protect against failure and fire caused by arcing.

  • The important items, which should be considered in Private Investigation Law, can include subjects, licenses, the scope of business, qualifying examinations, and supervisory and penal provisions. The subjects of Private Investigation Law should be permitted to be both natural persons and juridical persons in terms of providing various services, but should be permitted to be juridical persons and should be administered on a license system, even in order to ensure public interests. Concretely, the introduction scope of Private Investigation Law can be regulated to include the followings: that is, investigating the whereabouts identification of runaways and missing children, investigating the personal identification, habit, way of action, motivation, whereabouts identification, real child confirmation, association, transaction, reputation, and personality of specific persons or specific groups, investigating the whereabouts identification of missing persons, owners of government-vested properties or renounced properties, investigating the whereabouts of lost properties or stolen properties, investigating the causes of fire, character defamation, slander, damage, accident, physical disability, infringement on real estate or movable property, and investigating all sorts of accidents including traffic accidents, insurance accidents, and medical malpractices. In the qualifying examination, examinees' age should be restricted to be over age 25. The person, who is exempted from its primary examination, should be restricted to be the person, who has the career of over 20 years in related fields, in consideration of its equity with other certificates of qualification. In the supervisory institution, as the policy institution is the supervisory institution in many countries including France (the police) and Japan (public security committee), so the National Policy Agency should be the supervisory institution in consideration of management aspects. In the penal regulations, especially, we should clarify the management of personal information (personal information protection, personal information management), and so should prevent the infringement of people's basic rights, and then should ensure the public interest.
