Thermal imaging technology based on IR sensor with high transmittance through the fire smoke is considered as one of the advanced technology for the fire service. The present study has been performed to investigate the image saturation characteristics with thermal condition of target and background and evaluate the performance of image quality based on the contrast transfer function (CTF). For the present testing conditions, TIC using BST sensor did not show the image saturation and the image quality based on the CTF was proportional to the temperature difference between target and background. This study can be utilized as preliminary study to improve reliability and technical development of TIC.

This paper proposes the design of multiband repeater antenna with fire-fighting band for in-building mobile communication. The proposed antenna is composed of a center monopole and 4 parasitic elements on a circular plate. In order to realize good reflection coefficients at the multiband, mutual coupling between 4 parasitic elements and center monopole antenna is considered. The important parameters such as distance between parasitic element and a center monopole, and each height of a center monopole and 4 parasitic elements are simulated to obtain good antenna characteristics at the multiband. The diameter of 4 parasitic elements and a center monopole was fixed to 10 mm for easy design and manufacturing. The measurement results of reflection coefficients, 2-D patterns and gain agreed well with their simulation ones.

When the national disaster accident is occurred, it is difficult to maintain the mutual cooperation systems. In order to solve the problems, the construction of the national unified command wireless network is necessary. In this paper, the specified state of the characteristic frequency of the digital TRS wireless network constructed recently is investigated and analyzed. Through the analysis, the problems of the construction of the national unified command wireless network are grasped. To solve the problem, it is proposed that the digital TRS wireless network is connected with the satellite communication network, and connected with the existing wireless network, LMR. In the concretely it is proposed that the natural unified wireless network should be proceeded step by step. At first, for 2 years the existing networks of the Fire Fighting Agency, the Police, the Forest Service and so on must be utilized and prepared to link with TRS. The second, for 2 years it is carried forward a scheme to maintain the properties of the agencies concerned. Further, it must be prepared to connect with satellite network. At third, for 2 years all agencies concerned with the fire fighting and the disaster prevention must be unified, and the systems have to be promoted for the p1an of linkage of TRS network and the existing network. Next the agencies concerned have to be unified and the authority has to be intensified. When a disaster is occurred, the National Emergency Management Agency has to play a central role. In a local area it has to be given the Fire Fighting Agency an authority and a duty to get ready for each emergency situation.

In the event of a fire and a disaster, prompt and accurate alarms inside and outside the building are directly related to the minimization of damage and the success of life evacuation. However, due to unwanted fire alarms in automated fire detection systems, the number of dispatches by misunderstanding in the 119 service is increasing. This causes the insensitivity to the safety of building managers and the waste of the fire-fighting power. Therefore, in this study, the statistical databases and literature on unwanted fire alarms in Korea and abroad (USA, UK) were identified and the management systems for unwanted fire alarms were compared and analyzed to identify problems of statistics in the management systems for unwanted fire alarms.

This paper aimed to statistically analyze the impact of fire needs not considered in previous reports based on preventive and preparedness strategies of fire administration and fire budget.. The panel data came from 16 metropolitan councils from 2008 to 2018 and was statistically analyzed based on the preventive measures of the fire administration (agreement for building permission, specific target for fire-fighting, public use facilities, and special fire inspection [SFI]), preparedness of the fire administration (fire safety education [FSE]), response of the fire administration (mobilization for fire suppression [MFS] and mobilization for ambulance service [MAS]), and fire budget. In the results, SFI, FSE, and MFS had a significant negative influence on the fire budget. Meanwhile, MAS had a significant positive effect on the fire budget (p < 0.01). These results reflect public policy in Korea; there has been a paradigm shift in fire administration: from disaster acceptance (focusing on recovery) to disaster response (focusing on field response) to disaster preparedness (focusing on preparedness).

This research analyzed the operational status of fire protection system managers who execute self inspection of the fire equipment in the specific fire protection facilities and presented the improvement scheme. Being made up inquiry for job environment, institutional environment, and operational environment for the subject of fire protection system managers who execute self inspection to complement the fire equipment inspection by city public fire protection service, the issues of the operational status of the institution of fire protection system managers were positively understood. The research result showed the conflict among building owner, fire equipment inspector, and fire protection system manager was existed due to the legal and institutional inertia to the self inspection, so it is judged that mutual complementary and cooperative relation should be established.

It is possible to use wireless communication any time in every place because of well-developed wireless networks and mobile devices. The AVL(Automatic Vehicle Location) system, therefore, has made practical use in situation control, distribution industry, home delivery service, and ITS(Intelligent Transportation System) area. In this paper, we design and implement an AVL system in order to use for fire fighting activities such as emergency rescue and relief. To do this, first, we investigate and analyze the existing researches and systems related to AVL system. In details, we develop an AVL server and clients to support stable communication each other using wireless networks. Using AVL system, calling cars find the position of accidents quickly and the fire defense headquarters control unforeseen accidents efficiently because the state of calling cars are confirmed in real time by their GPS data.

Purpose: This paper aims to clarify the problems and to examine the improvement methods by investigating the management condition of local-designated cultural property of which management is relatively poor in comparison with state-designated cultural heritage. Method: In order to grasp the management situation of the local-designated cultural heritage, a research on cultural heritage management situation and problems will be carried out with 35 cultual heritages in Goryeong-gun. Also, the improvement methods about the property type vulnerability on the basis of interview with cultual property managers, fire-fighting officers and civil servants, etc. Results: Local cultural heritages were investigated to be very vulnerable to the fire of wooden buildings, the theft of movable cultural heritages, and the effects of wind and water damage. It is because cultural heritages are scattered over wide areas fundamentally. As the result, it has difficulty in the patrols of police officers and fire fighters, and in the situation that it lacks disaster monitoring and CCTV for countermeasures to replace them, electronic security including fire hydrant, sensors, etc and fire extinguishing facilities and so on. It is difficult for local governments managing local-designated cultural heritages to enhance their management systems directly due to their lack of budget and manpower. Conclusion: In order to strengthen disaster and safety management system for the cultural heritages designated by local governments, they have to clarify disaster countermeasure task of fire fighting, police, and cultural heritage managers prepare their manuals, and systematize them through disaster drill mainly in local autonomous governments. Also, so as to establish a surveillance system every day, they have to enhance the community for local cultural heritage manage consisting of local volunteer fire departments, local voluntary disaster prevention organizations, volunteers, etc.

Special judicial police officer are exercising their right to investigate areas that require expertise that is difficult for ordinary police to investigate. The fire special judicial policer are also like this, and since they investigate the specialized field of fire offenders, they require not only expertise in the firefighting field but also professional capabilities in the investigation. To achieve this, there must be improvements in the selection process for fire and special judicial police officers to secure excellent investigative personnel. There is a lack of educational facilities and training content that can systematically educate selected investigative personnel and strengthen their expertise, so improvements are needed. must also be done. Laws on controversial areas surrounding the fire and special judicial police must be reorganized and poor investigative conditions must be improved so that the fire and special judicial policer can properly perform their role.

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.
