When the fire occur in a special place as High-rise building, find the solution from minimize the potential risk factors that caused to develop the human and materials damage by analysis. Through preventive activities are suppression of the fire occurrence or prevent the fire and extinguish the fire early. However, introduction of scientific suppression program could predict in advance the progress of the fire, or to block the path by using Intel Regent or Fire grid.

This paper is a study to solve the malfunction of Fire Detection System and to react swiftly in case of fire. if a fire occurs because of malfunction of the fire receiver, it may not be possible to respond appropriately. in order to solve this problem, Fire Detection System using IoT, the manager studied the method of confirming the fire occurrence with mobile phone Application. We propose a wireless Fire Detection System by building a server and a client using a micom and a mobile phone application. This is to reduce the damage caused by the fire.

A study on the fire scenario proposal of residential facilities by using fire statistics. as a result of analyzing residential facilities fires by using fire statistics of national emergency management agency during 2007~2012, fires from carelessness were the most causes. specially, fires during food cooking among carelessness showed the highest occurrence frequency, and followed sparks, neglecting fire sources, and cigarette stubs in order. through this the study suggested fire scenarios according, It is believed that can be used as basic data for applying a secure building in a fire using a basis for fire safety design of buildings in the future this.

In this paper, we studied fire position recognition and alarm system when we acquired CCDcamera image of fire region and position. We proposed effectively extraction system of boundary of fire region using RED Filtering, and applied 2-graylevel image method to fire boundary extraction. Finally we can make system of fire position and region using mask extraction and matching for fire recognition. For the purpose of experiment result, we effectively recognized that the tire occurrence position and region have steadily spread.

In this paper, the writer attempts to clarify causes by general man and weather factor on forest fire occurrence in Kosong-Area, 1995-2001. The major results are summarized as follows: The forest fire at Kojin-ri, Sonyusil-ri and Majwa-ri occurred at the same area over 3 times and that Hakya-ri, Songdae-ri and Inhung-ri, at the adjoining land over 3times. In the total 46 times of forest fire, fire frequence was greatest in March(11 time) and April(11 time) followed by November(7 time), January(6 time), February(6 time). December(3 time), October(2 time). Hours on frequent forest fire are from 11:00 till 18:00. Number for forest fire occurrence by causes was greatest in military training followed by burning paddy fields, debris burning, burning agricultural debris, visiting a grave, cigarette and arson. Frequent forest fire in Kosong-Area coincide not only with above normal temperatures, but also with below normal relative humidity. When the strong winds appear at Kosong-Area, the properties of daily surface chart re the south high and north low pressure pattern in the Far East Asia.

21C, Multiplex Cinema Theater is made from movie industry developed and become a place where we can spend our free time and consuming. But, theater users, who are many and unspecified persons, are short of information on the Multiplex Cinema Theater, so that they may be injured or killed at the occurrence of fire accident. Particularly, Multiplex Cinema Theater is a place that underground space or top floor in highrise building had many people in theaters. However, this problem is difficult to solve that to protect human being and properties at the occurrence of fire accident in the Multiplex Cinema Theater, In order to overcome such problems, Multiplex Cinema Theater need fire protection solutions facilities concerning particulars to pay attention to the safety on a fire and evacuation. This study analysed Multiplex Cinema Theater concept and computer simulation for risk point.

This paper reviews past literatures relevant to fire-resistance properties of high strength concrete and investigates spalling mechanism of high strength concrete in fire. First, literatures were reviewed on spalling occurrence and fire-resistance methods. Second, a chemical change of concrete components in an elevated temperature was presented. Finally, the mechanism of the spalling occurrence and spalling resistance were examined in terms of hybrid fiber content. The focus of the experimental study as part of this research is to investigate the effects of fire on the variation of thermal properties of high strength concrete, which tends to be used in super tall buildings. This experimental study was devised to investigate the fire-resistance performance of high strength concrete containing hybrid fibers. A total of 48 test specimens were exposed to high temperature ranging from $100^{\circ}C$ to $700^{\circ}C$, including room temperature (${\sim}20^{\circ}C$). Test results provide valuable information regarding fire-resistance properties of strength concrete with 100 MPa or greater.

As a results of comparing with fire occurrences and gross national income(GNI), annual fire increasing rate has been 5.6%, and that of GNI has been 11% for the past 55 years. As GNI shows 5.4% higher than fire occurrences, economy growing rate is faster than that of fires. In addition, study has been done every 10 years from 1950's to 2000's. Fire occurrences increase twice as much annually and GNI increases above 3.3 times as much.

In this paper, we propose the method of fire detection. A wide distribution of CCTV cameras (Closed Circuit Television) in many public areas can be used not only for video surveillance systems but also for detecting fire occurrence. A proposed approach is based on visual information through a static camera. Video sequences are analyzed to find fire candidates and then spatial analyses procedure for detected fire-like color foreground is carried out. From the simulation results, our method showed the best performance when spatial and temporal fire candidates changes rapidly and close to fire motion.
