Korea rapidly arranged urbanization and overpopulation with high growth of economy and all kinds of decrepit facilities are scattered all over the downtown. If there is a strong wind in fire, fire is rapidly increased by various fire spread factors. And Korea cannot build prediction model of urban fire combustion phenomena because there is no studies that physically explains the suitable flame phenomena for its real state. In this study, based on the Japanese Urban fire simulation to target the building congested Area and suitability of fire risk assessment were reviewed.

본 연구는 국토의 계획 및 이용에 관한 법률에 규정된 방재지구에 대하여 관련 연구 자료 및 통계를 통한 지구지정 현황과 운영제도의 문제를 검토한다. 건축물·인구밀도가 밀집된 지역으로서 시설 개선 등을 통하여 도시지역 내의 재해예방을 위해 지정이 필요한 시가지방재지구는 방재지구지정 의무화제도가 도입된 이후 서울시 등 여러 곳에서 지정되었으나 대부분 폐지되었고, 현재는 전국에서 전라남도에 5개 지구가 지정되어 있다. 지구지정 감소의 원인은 방재지구의 지정 및 관리제도가 현실적이지 못한데 기인한다. 시가지방재지구는 면적에 비해 인구가 밀집된 도시지역의 재해에 효율적으로 대응할 수 있는 방재계획이며, 활성화를 위하여 지원방안 및 인센티브가 포함된 구체적인 관리 운영 기준 마련이 필요하다.

The proportion of buildings over 30 years old in Korea has increased, from 29.0% in 2005 to 37.8% in 2019. These old buildings were built during a time in which there was a lack of building-related safety standards in areas such as fire safety performance. Worse, during their years of use, many such old buildings have had illegal changes and extensions made, making them more vulnerable in terms of safety. Fire safety investigations are being conducted to prevent large-scale disasters in multi-use buildings, but no investigation has been conducted at the regional district level, where small-scale old buildings are concentrated. Therefore, to identify fire risk factors in the old building district where old buildings are concentrated, the composition characteristics of the buildings were first analyzed. To examine the spatial characteristics of old building districts in order to derive fire risk factors, the results of this analysis based on the structure, use, roof type, and year of approval for use are as follows. It was found through our analysis that as of the date of approval for the use of the building, the main structure of the building has the greatest impact.

우리나라의 도심 곳곳에 자리잡고 있는 노후화된 건축물 밀집지역 및 화재경계지구는 재해로부터 매우 취약하며, 특히 방내화성능이 떨어져 화재가 인근 건물로 확대되어 대규모 도시화재로 전환될 위험성이 높다. 따라서 단일건물 화재에서 도시화재로의 확산 메카니즘중 불씨의 비산에 따른 화재확대를 시뮬레이션화하기 위하여 불씨발생량 실험을 한 결과 기존의 연구 성과와 더불어 불씨를 고려한 새로운 연소시뮬레이션 모델을 구축하였다. 또한 연소 시뮬레이션 모델을 실시가지에 적용해 방재마을 만들기 현장에서의 활용 가능성을 모색하였다.

As population grows and urban facilities are concentrated in specific areas due to recent urbanization and industrialization, cities have structures vulnerable to both natural and man-made disasters. Most of these structures, whether buildings or residential houses, are left in a defenseless state if not given the appropriate check-up before they are built. The process of rapid urbanization without establishing the proper urban fire risk assessment will surely lead to disasters. This phenomenon occurred during the process of rapid urbanization and maybe said the result of chaotic urban expansion where modern urban infrastructure is not yet equipped in the city. Under the said circumstances, propagation processes of Korean urban fire cases were investigated to establish fire risk assessment system. Moreover, this paper explains the experiment performed for establishing urban risk assessment model. The said experiment was conducted using the new urban fire risk assessment model.

The main purpose of 1-1-9 Caller Location Information System is to identify and display the precise location of emergency incidents such as natural or man - made fires, medical emergencies and accidents. The state - of- the - art technologies such as Am (Automatic Number Identification), GIS(Geographical Information System) and GPS (Global Positioning System) were applied and integrated in the system for efficient and effective location identification. It displays a radius of 25M, 50M and 100M on the map after location identification. The system can also provide the shortest path to an incident location from a fire station or a fire engine. In case of a fire breakout in or near a building, the attribute information of the building, called a building attribute card, is displayed along with the map location. The system then matches the information with the fire situation and sends an alert to a responsible fire station by phone or fax in order to help promptly react to the problem. An attribute card includes the critical information of a premise such as building's location, number of stories, floor plans, capacity, construction history, indoor fire detection and Prevention facilities, etc.

In order to clarify the impact of variation of albedo on the atmospheric boundary layer caused by the density of building in urban areas, both satellite data analysis and numerical experiments were carried out. Utilized satellite data were multi-spectral visible data detected by the Korea Multi- Purpose Satellite -2 (KOMSAT-2), and the numerical models for the estimation of surface heat budget are Albedo Calculation Model (ACM) and Oregon State University Planetary Boundary Layer model (OSUPBL). In satellite data analysis, the estimated albedo in densely populated building area is lower than other regions by 17% at the maximum due to the shadow effect of skyscraper buildings. The surface temperature reached $43.5^{\circ}C$ in the highly dense and tall building area and $37.4^{\circ}C$ in the coarse density area of low buildings, respectively. However, the low albedo in densely integrated building area is not directly related to the increase of surface air temperature since the mechanical turbulence induced by the roughness of buildings is more critical in its impact than the decrease of albedo.
