The purpose of this article is to search stakeholders' recognition related to Fire Construction Surveillance system; a client(order), fire fighting officer, supervision company, construction company, design company, other. The paper provides 4 important things. Firstly, a client(order) suggested the lowest recognition in the needs about the need of separation order, that of contract for any construction work limited registered companies, and that of standard price for engineering.. Secondly, the design company is lowest recognition in guidance and control participating in construction-design phase. Thirdly, the design company is lowest in adjustment about manpower-allocation according to allocation criteria of technical manpower. Fourthly, a client(order) and supervision company are relatively lower than other stakeholder in necessity on special education and training system for auditor in fire protection construction. Almost all related matters are related to more or less stakeholders' interest.

The study seeks to cooperate with the investigation of a fire investigation based on public-private partnership. Fire protection systems provide a wide variety of viewpoints from the perspectives of design, construction, management, maintenance, maintenance and maintenance systems at a particular point in time, construction, management, and maintenance systems. What is controversial is that there are illegal activities such as illegal activities of the Patent Office, misconduct of construction work and unreasonable construction of construction works.As a theoretical framework, the present study identified the four key elements of a successful disaster response system : responsiveness, control, professionalism, and bias.

In this study, the experiment was conducted on a fire door(W × H = 0.98 m × 2.19 m) installed on the vestibule. The effective leakage area for each opening angles and closing forces derived from the impulse-momentum equation was compared and analyzed with the experimental results. As a result of the experiment, the major factors affecting the door closing forces were the pressure difference and the area of the door. The difference of door closing forces between measured and calculated values by the impulse-momentum equation showed a deviation of less than ±15% at the opening angles of 5°to 10°. At the door opening angle of 2.5°, the dynamic pressure was much higher than the measured static pressure, and this pressure difference is estimated to be air resistance acting to prevent the door from being completely closed.

In accordance with the revision of "Special act on the safety control of publicly used establishments", this study is aim to measure the change in evacuation time due to whether safety facilities, etc. are installed of a room escape cafe business and kids cafe business(hereinafter referred to as "New publicly used establishments"), which were added as new targets of the publicly used business from June 8, 2022. In the case of new publicly used establishments or publicly used establishments whose owners are changed after the revision of the relevant laws, safety facilities, etc. are installed and maintained under the "Special act on the safety control of publicly used establishments", but in the case of existing businesses that have been operating even before the revision of the law, the business continues without safety facilities, etc. installed because the revised law is not retroactively applied. The purpose of this study is to compare and analyze the change in evacuation time by measuring the evacuation time to operating before the revision of the law to simulate evacuation at existing new publicly used establishments without safety facilities, etc. and measure the evacuation time at new publicly used establishments with safety facilities after the revision of the law

The purpose of this study is analyzing temporal flow about 20 detailed performance items in the "Housing Performance Grading Indication System". This study try to figure out situations according grade in detailed performance item and to analyze change item about 112 cases(2 cases in 2006, 15 cases in 2007, 46 cases in 2008, 49 cases in 2009), from January 9, 2006 which system is undertaken, to October, 2009. This system consists of 5 main performance section, 14 performance categories and 20 detailed performance items. 5 main performance parts are Noise and Acoustics(Light-weight impact sound control, heavy-weight impact sound control, sound control of toilet, sound control of party wall), Long-life(flexibility, remodeling & maintenance, durability), Landscape & Indoor Environment(landscape, formaldehyde control & ventilation, daylighting, thermal environment), Welfare & Barrier-free(playground and community center, welfare space, barrier-free design), Fire Safety(fire safety, safe place, fire-resisting quality). Total efficiency about housing can understand systematically of 20 perfomance items though this research.

The purpose of this study is a proposal about the flexibility of the performance category to revitalize the "Housing Performance Grading Indication System". This system consists of 5 main performance parts, 14 performance categories and 20 detailed performance lists. 5 main performance parts are Noise and Acoustics(Light-weight impact sound control, heavy-weight impact sound control, sound control of toilet, sound control of party wall), Long-life(flexibility, remodeling & maintenance, durability), Landscape & Indoor Environment(landscape, formaldehyde control& ventilation, daylighting, thermal environment), Welfare & Barrier-free(playground and community center, welfare space, barrier-free design), Fire Safety(fire safety, safe place, fire-resisting quality). The flexibility of the performance category is conformed to Long-life housing related grading and can realize the Long-life housing in response to resident needs about the space rearrangement. Now, The flexibility of the performance category is limited to the evaluation of the private space, that is, the Skeleton evaluation. This study would suggest alternatives to improve uppermost limits through analyzing 60 examples from January 9th 2009 to October 30th 2008. The flexibility of the performance category is possible to estimate not only the Skeleton evaluation but also the Infill evaluation in response to social changes.

최근 건축물이 대형화, 복잡화되면서 건축물내 거주자의 피난안전성이 관심의 초점이 되고 있다. 국내 건축물은 용도에 따라 관계법령에 의한 배연창 또는 기계적 배연설비를 설치하도록 규정되어 있다. 화재시 거주자의 피난안전성을 확보하기 위하여 화재실의 제연이 매우 중요하다. 본 연구에서는 배연창 크기의 변화와 스프링클러 설비의 작동이 화재실 연기층 높이와 온도 조건에 미치는 영향을 화재 시뮬레이션프로그램인 CFAST를 이용하여 평가 하였다. 연구결과 배연창 면적이 증가할수록 5MW 화재 크기 이하에서는 연기층 높이와 온도에 미치는 효과가 증가하나 화재크기가 10MW 이상 커지면 배연창의 면적과 연기배출 효과와의 상관성이 떨어진다. 스프링클러 설비가 작동하고 배연창이 열릴 경우에는 화재크기와 상관없이 인명안전기준이 만족되었다. 법규에 의한 일률적인 배연창 면적의 적용보다는 건축물의 용도 및 규모에 따라 화재시나리오를 선정하고 시나리오에 따른 화재 크기에 따라 적절한 크기의 배연창을 적용하여야 하며 실제 실험이나 시뮬레이션을 통한 검증이 이루어져야 한다.

본 연구에서는 화재실과 인접부 제연구역의 차압 및 방화문의 개방력을 측정할 때의 문제점을 분석하고, 객관적인 방법에 의해 측정된 실측값을 제시하는데 있다. NFSC 501A의 제연설비 가동 시 출입문의 개방에 필요한 힘은 110 N 이하로 규정하고 있다. 제연설비가 설치된 공간에서 제연설비가 작동하지 않을 때는 KS F 2805의 시험방법에 의해서 개방력의 측정이 가능하지만 제연설비가 작동되었을 때는 화재실과 제연실의 차압에 의해 발생되는 추가적인 힘이 필요하므로 기준에서 제시하는 시험방법은 신뢰성이 부족함을 알 수 있다. 제연설비 가동 전 완전히 폐쇄된 상태의 개방력은 아날로그측정기($F_a$) 27.8 N, 디지털측정기($F_d$) 27.4 N을 각각 나타냈다. 그리고 문이 $5^{\circ}$ 개방된 상태의 개방력 $F_a$는 33 N, $F_d$는 33.6 N을 나타냈다. 제연설비가 작동되고 완전히 폐쇄된 상태의 개방력 $F_a$는 45.3 N, $F_d$는 46.9 N을 나타냈고, 문이 $5^{\circ}$ 개방된 상태의 개방력 $F_a$는 77.6 N, $F_d$는 76.0 N 등으로 확인되었다. 따라서 현재의 KS F 2805에서 제시하고 있는 기준과 상이하므로 적절한 기준의 검토가 요구된다.

본 논문에서는 소방전원 및 소방전원 부족시 용량 보완을 위한 인터록 시스템의 한계점 등을 분석하고 소방전원 보존형 발전기(RFP)의 작동방법 등을 제시하여 화재와 같은 상황에 효율적으로 대응할 수 있는 방법을 제시하는데 있다. 소방전원보존형 발전기에서 일괄제어방식은 발전기에 과부하가 걸리면 소방전원보존용 제어기에서 신호를 발신하여 소방부하는 남겨두고 비상부하용 주차단기를 일괄 차단하고, 발전기가 마지막까지 소방부하에 전원이 공급되도록 한 시스템이다. 순차제어방식은 과부하가 걸리면 소방전원보존용 제어기에서 1차 신호를 발신하여 설정된 비상부하의 1단계 부하를 차단한다. 그리고 지속적인 감시 상태에서 소방부하가 증가하여 발전기가 다시 과부하가 걸리면 제어기에서 2차 신호가 발신하여 비상부하의 2단계 부하를 차단하는 시스템이며 각각의 작동 상태를 표시하는 표시장치를 가진다.
