  • The new SOLAS regulation permits the alternative design approach for the approval of designs which deviate from those where prescriptive rules apply. The new approach is being promoted by recent advances of noble designs such as those employing large public spaces in passenger ships. From the respect of fire safety, it is needed to show that the level of safety of new design is equivalent to what can be achieved from the prescriptive rules where the fire simulation is regarded to be the essential tool. This paper provides an overview of the process of performance-based design of the smoke extraction system in a cafeteria of a ROPAX. FDS, a CFD fire simulation software is used to show that the field-model software can improve the fire safety over what are expected from prescriptive rule sets or zone-model application.

  • The big issue in fire and life safety protection in atriums is that hot smoke can spread vertically via the atrium openings, and impact atrium floors remote from the fire. Three different strategies to provide fire and life safety protection for atrium space were evaluated in this study, using the FDS model. Strategy A is the atrium protection approach addressed in the Korean Building Fire Protection Code, where atria are required to be enclosed with fire shutters from the $2^{nd}$ floor to the atrium top, and the ground floor is allowed to open to the atrium; in this case, no smoke control is required. Strategy B is the atrium protection approach, with smoke control provided in accordance with NFPA 92B; in this case, no atrium floor is enclosed. Strategy C is the atrium protection approach, in which some of the upper atrium floors are enclosed (the case of the top atrium floor being enclosed is evaluated in this study), and atrium smoke control is also provided to protect the lower atrium floors.

  • With the development of the Korean economy, the number of arson fire has been radically increased and become a huge problem and issue in Korea Society for last several decades. This study is to establish the fire life safety strategy regarding the arson fire through performing the computer simulation based on fire scenarios with researching domestic fire statistics and cutting edge techniques and methods for fire characteristics and fire dynamic. In addition, to design the fire life safety strategy depending on the arson fire pattern, the flow and characteristics of fire flames and smoke is analyzed by the computer modeling.

  • Reliability of fire protection systems is often discussed, written about, and even put into codes and standards. However, reliability is seldom considered for the fire protection system as a whole. Why does this happen and why should the designer consider the system as a whole\ulcorner Existing codes and standards incorporate the concept of reliability usually In the form of key component redundancy for some parts of a system. The "Fire Safety Concepts Tree" presented in the National Fire Protection Association Guide 550, Guide to the Fire Safety Concepts Tree, provides a starting point for considering the performance of a water based fire suppression system. Considering fire protection objectives for water based fire suppression systems, means of evaluating system reliability can be developed. This development requires identification of system components that are significant to the overall system reliability.

  • 최근 초고층화, 지하 공간 활용 등 미래 환경이 변화함에 따라 새로운 유형의 재난이 발생하고 있으며, 재난의 대형화, 한미 FTA 체결 등 소방산업 외부환경이 변화하고 있다. 이로 인해 어느 때보다 소방산업의 기술혁신 필요성이 대두 되고 있다. 이와 더불어 우리나라 소방제품은 선진국의 소방산업 제품에 대하여는 기술경쟁에서 어려움을 겪고, 동남아시아, 중국 등의 소방제품에 대하여는 가격경쟁력이 취약한 문제를 안고 있다. 이러한 문제점을 극복하기 위해 국내 소방산업에서는 R&D 활성화를 통한 소방산업 기술자립화를 확립하는 것이 무엇보다 중요하다. 이에 본 연구에서는 국내 R&D 현황 과 국내소방산업 R&D 현황을 분석하고, 이에 대한 문제점 및 개선점을 고찰하여 R&D 활성화를 통한 국내 소방산업 육성방안을 제시하고자 한다.

  • 본 연구에서는 건물 화재의 위급한 현장 속에서 침착하면서도 신속하게 탈출해야하는 상황을 가상 체험하는 VR 기능성 게임을 개발하였다. 사용자는 바이브(VIVE) 양손 컨트롤러를 이용하여 화재 건물 속에서 방화문과 계단, 복도을 통해 출구로 탈출해야한다. 화염이나 연기로 인하여 더 이상 진행하지 못하면 돌아서서 다른 통로로 진행할 수 있다. 호서대의 한 건물을 모델링 하였으며, 학생들에게 본 게임을 체험시키고 사용성과 효과성을 중심으로 설문 조사하여 그 반응 결과를 분석하였다.

  • Korean city had been rapid developed through high industrialization and rapid economic growth after the 1970's. The city development process was guaranteed the fulfillment of city function through the city expansion based on New Towns and satellite cities rather than the reformation of existing city. This city expansion caused by degrading of city, being backward and producing many problems. To solve this problems, it was considered the rehabilitation of retarded function with rejuvenation such as a special law accelerating urban renaissance and reorganization project. Also a fire protection performance did not satisfied the required conditions of modern FPP system, such as the function deterioration of building facilities, the technological development with FPP facilities, changed fire laws and building occupancy for social needs. Insufficiency of requirements depreciated the building value and intimidated a safety of residents. To solve this problem, the improvement of FPP was essentially required and also strongly recommended an analysis and a comparative study between the required FPP of existing building and it improving effective FPP. Therefore, purpose of this study is that establish the basic data to construct a system to analyze and compare the building FPP.
