For the fire-fighting industry to advance, it is necessary to conduct research on which parts of the fire-fighting law should be changed from the system level, and to study the opinions of the fire-fighters whoa re working in the fire-fighting industry today, and to identify what needs to be changed. Moreover, it is necessary to become aware on the preventive measures to take to avoid fire so that the citizens can lead stable life. Design business among the fire-fighting facility business, it is the fire-fighting facility business that serves as the most basic when constructing building structure. This is an important legal matter that follows the fire-fighting business, fire-fighting audit business and even the maintenance and management business. This research sought to help the fire-fighting industry to contribute to the life of the general public and to increase welfare by identifying the problems pertaining to the fire-fighting facility design business among the fire-fighting industry so that the industry can become the fire-fighting industry that the citizens are interested in. Moreover, direction for advancement is proposed. As for the improvement measures for the fire-fighting policy pertaining to the fire-fighting facility design business, it is divided into the machinery and electricity fields in terms of the legal system pertaining to the general fire-fighting facility design business. Likewise, specialty in design is deficient. Thus, it should be integrated in a systematic level to contribute to the safety of the general public.

Under the Act amended on August 4, 2011, a special fire-fighting investigation was conducted by the relevant person (owner, manager, oil refineries), and the responsibility was also given to the relevant person. Instead of directly entering all existing fire-fighting targets and investigating the maintenance and management status of fire-fighting facilities, the fire-fighting agency selects and visits some targets every year, checks the maintenance and management status of fire-fighting facilities, corrects them, and imposes fines, etc. Reasons for the introduction of the system were the establishment of a private autonomous correction system by strengthening the responsibility of officials, lack of firefighting professionals, possible corruption due to frequent public contact, and responsibility of fire agencies. However, many problems arose even after the introduction of a special fire investigation system. A special fire investigation, one of the fire safety systems, checks whether related public officials and especially fire officials are properly installed, maintained and managed in accordance with relevant laws. Special firefighting investigations were introduced as firefighting inspections at the time the firefighting law was enacted in 1958, and have undergone a revised process more than 30 times until recently. Firefighting Facility Installation, Maintenance and Safety Management Act", the existing firefighting inspection was changed to a special firefighting investigation and accepted. At the time of enactment of the Fire Service Act in 1958, a special firefighting investigation was introduced as a firefighting inspection, and until recently, more than 30 revisions have been made. In 2003, as the existing fire fighting system was divided into four laws, it was approved by changing the existing fire fighting inspection to a special fire fighting investigation in the "Fire Fighting Facility Installation, Maintenance and Safety Management Act".

Purpose: Currently, in the case of domestic fire fighting facility design, it is difficult to secure highquality manpower due to low design costs and overheated competition between companies, so there is a limit to improving the fire safety performance of buildings. Accordingly, AI-based firefighting design solutions were studied to solve these problems and secure leading fire engineering technologies. Method: Through AutoCAD, which is widely used in existing fire fighting design, the procedures required for basic design and implementation design were processed, and AI technology was utilized through the YOLO v4 object recognition deep learning model. Result: Through the design process for fire fighting facilities, the facility was determined and the drawing design automation was carried out. In addition, by learning images of doors and pillars, artificial intelligence recognized the part and implemented the function of selecting boundary areas and installing piping and fire fighting facilities. Conclusion: Based on artificial intelligence technology, it was confirmed that human and material resources could be reduced when creating basic and implementation design drawings for building fire protection facilities, and technology was secured in artificial intelligence-based fire fighting design through prior technology development.

Presently, there is no legal regulation pertaining to the installation, maintenance, management and operation of fire-fighting facilities in single housing in Korea, relying instead on the awareness of the residents which hopefully will prevent fire. Likewise, accident prevention effort is very limiting and weak. Accordingly, this research examines current situation in which fire results, identifies root causes and studies application of regulations and develop design measures centered on the single housing that is most afflicted with fire. As part of the measure to prevent fire that afflict housing, it is necessary to classify single housing as specific target for fire fighting just like the joint housing among the types of the building structures that are classified according to the usage on the "Appendix Chart I of the Enforcement Ordinance of the Construction Law" for management purpose. Moreover, it is necessary to make the installation of fire-fighting facilities such as simple sprinkler facility for residential area, fire extinguisher, warning system and others for the sake of the senior citizens and disabled people who reside in single housing, mandatory.

This study suggests a solution regarding the effects of apartment facility maintenance and fire safety facility maintenance on the residential satisfaction of residents. The results are as follows. Firstly, facility maintenance had a negative effect on residential satisfaction. Analysis revealed that residential satisfaction decreased the more breakdowns there were in the facilities. This revealed that when maintenance staff neglect the residents' complaints due to the repetitive aspect of their jobs, there was a negative effect on residential satisfaction; therefore, residential satisfaction must be increased by maintaining the facilities well and training support for maintenance staff. Secondly, fire safety facilities had a negative effect on residential satisfaction. Analysis revealed that residential satisfaction decreased the more malfunctions there were in the fire safety facilities and the more replacements there were in fire fighting equipment. This revealed the importance of safety and the fact that the apartment heavily relies on fire safety facilities because there may be a low awareness regarding safety; therefore, maintenance staff must lower the damage from fire safety facilities and to increase the residential satisafaction of residents. Lastly, there needs to be repetitive training and education for residents regarding fire fighting and evacuating in accordance with the fire fighting plan as a means to strengthen residents' safety awareness.

A systematic experimental study is carried out for the fire fighting monitor nozzle of 65A diameter to design and manufacture a new nozzle with better water spray performance than available domestic nozzles. The nozzle inlet pressure, flow rate and reach for the discharged water from the nozzle are measured by utilizing the experimental facility consisting of two pumps and piping system with a flow meter and pressure gauges. It was found that the baffle position and baffle head chamfering were the most sensitive design factors to be remarkably changed in the flow rate of the discharged water. Also, It was confirmed that the baffle position and the water exit area had the significant effect on the change in reach distance. The results obtained from this study are expected to be used effectively to design new nozzles with excellent spray performances and also to validate numerical analysis results for evaluating the water spray performance of fire fighting monitor nozzles.

The purpose of this study is to investigate the preparation time of fire-fighting water for public fire hydrants and ground, underground fire hydrants. The equipment preparation time for stage 1 was 20.50 seconds for ground type and 24.67 seconds for underground type. The reason for this difference in preparation time is that an underground fire hydrant requires additional standpipes to connect to the main conduit of Paru and the underground hydrant, which open the manhole cover. Water tank Maintenance joint with water hose male coupling of the second stage was similar to that of the ground type of 48.50 seconds and underground water tipe of 49.00 seconds. This is because the operation of connecting the fire hose to the maintenance tank of the water tank car is the same. In the third stage, the water pipe connection was 43 seconds for ground type and 174.33 seconds for underground type. The reason why the time for connecting the water pipe to the fire hydrant is large difference is that the underground fire hydrant is opened by opening the manhole cover, After connecting the stand pipe to the fire hydrant, the additional process of connecting the water pipe to the stand pipe is required, which is considered to have greatly increased the time required. The opening of Water Control Valve and spindle Valve in the fourth stage was 66.50 seconds for the ground type and 78.83 seconds for the underground type. This difference is due to the fact that the spindle of the ground fire hydrant is located on the main body and can be easily opened, but the underground type is located next to the main body under the manhole and requires additional time to connect the opening equipment.
