방창훈 국가유산방재학회 2022 문화재방재학회 논문집 Vol.7 No.1

This research examined comparison of awareness and performance of firefighters’ standard operation procedures at cultural heritage disaster sites. Overall, firefighter’ knowledge of standard operation procedures was relatively low, with 2.81 in their 30s by age and 2.87 in 6-10 years by work experience. The awareness and performance of the fire response procedure for wooden cultural properties were relatively high for those in their 40s by age for 6 to 10 years by work experience and for sobang-jang by rank. As for the improvement of standard operation procedures, 53.8% of the respondents said “production and distribution of actual cases in accordance with standard operation procedures,” 36.6% said “easy to access from smart phones by producing standard operation procedures,” and 32.3% said.

방창훈,허만동 한국방재학회 2011 한국방재학회지 Vol.11 No.1

본 연구에서는 소방방화복의 무게가 최대 신체활동 후 신체의 평형성과 민첩성에 미치는 영향을 조사하여 소방공무원의 안전을 위한 기초자료 제공을 목적으로 한다. 신체의 정적평형성 평가를 위하여 눈감고 한발로 서기와 동적평형성 평가로는 평균대걷기를 실시하였으며, 신체의 정적민첩성 평가는 전신반응검사 동적민첩성 평가는 반복 옆뛰기를 실시하였다. 연구결과 최대지친 상태에서 소방방화복의 무게는 신체의 정적평형성과 동적민첩성에 영향을 미치는 것으로 나타났으며 향후 소방공무원의 안전을 위한 실제적인 연구에 유용할 것으로 판단된다. The aim of study intends to investigate effect of weight of fire-protective clothing for physical balance and agility after max-imum physical activity and to provide the base data for the safety of firefighter. For evaluation of static and dynamic-balance, theclosed-eyes foot balance and the beam-walking were performed respectively. For evaluation of static and dynamic-agility, thewhole body reaction and the side-step were carried out. This study demonstrates that after maximum physical activity, the weightof fire-protective clothing effects on physical static-balance and dynamic-agility and suggests that it could be useful for actualsafety field studies of firefighters.

복사열에 노출된 작업복의 열적특성에 관한 실험적 연구

방창훈,이진호,예용택 한국산업안전학회 2002 한국안전학회지 Vol.17 No.3

The purpose of this study was to present the thermal characteristics of the working uniform exposed to the radiation heat. The effect of exposure time and exposure distance on the changes and the relationship between physical properties were investigated experimentally. Regardless of the kind of working uniform, the surface temperature of the working uniform with exposed time sharply increases as exposed distance is more close and the reaching tie of steady state is shorter. The surface temperature of working uniform exponentially decreases as exposed distance become more distant. For the safety of the working man, it is necessary that he work far away at a fixed standard distance from the radiant heat source.

방창훈,김정수,예용택 한국안전학회 2001 한국안전학회지 Vol.16 No.3

The objective of the present work is to examine the effect of inclined angle of channel with multi heat source on thermal stability of electronic equipment. The heat sources are mounted on both sides of channel walls by two kinds of configuration such as the zig-zag md symmetric on. Conductive heat transfer was estimated by using of thermocouples and heat flux sensor. Thus, convective heat transfer and mean Nusselt number could be obtained. With increased inclined angle, the convective heat transfer coefficient was decreased. When inclined angle was smaller than 30 degree, The average Nusselt number of Big-zag configuration was larger than that of symmetric. Furthermore, when protruding ration was 0.082, the temperature was strongly affected by inclined angle. whereas, when protruding ration was 0.25, the temperature was strongly affected by heat source configuration.

방창훈,권정숙 한국화재소방학회 2020 한국화재소방학회논문지 Vol.34 No.3

The aim of this study was to investigate the wearing acceptability of chemical protective clothing during fires and toprovide basic data for the safety of firefighters. The results of the study were as follows: Wearer acceptabilities of chemicalprotective clothing under static movement (e.g., looking at the ceiling with maximum head bending, wrapping one’s armsaround oneself, sitting obliquely on the floor, and maintaining a crouching position) were 21.7%–47.8% lower than thoseof general uniforms. When wearing chemical protective suits, the acceptability under static movement was statistically low(p < .001). Wearer acceptabilities of chemical protective clothing under dynamic movement (e.g., running, lifting a heavyobject (20 kg) up to the waist, lifting and moving a heavy object (20 kg) by 1 m, lifting a stretcher and walking forward,and lifting a stretcher and walking backward) were 19.2%–47.8% lower than those of general uniforms. When wearingchemical protective suits, the acceptability under dynamic movement was also statistically low (p < .001). 본 연구는 소방훈련시 화학보호복 착용시 동작만족도를 분석하여 소방공무원의 안전을 위한 기초자료 제공을 목적으로 한다. 정적 동작만족도는 일반근무복에 비하여 화학보호복의 경우 21.7%~47.8% 정도 낮게 나타났다. 화학보호복 착용시 정적 동작자세에서는 고개 최대한 젖혀서 천장보기, 두팔 몸 앞에서 끌어안기, 비스듬히 굽혀 앉기, 과도하게 쪼그리고 앉기의 동작들이 낮게 나타났으며 통계적으로도 유의하게 낮은 결과를 보였다(p < .001). 동적 동작만족도는 일반근무복에 비하여 화학보호복의 경우 19.2%~47.8% 정도 낮게 나타났다. 화학보호복 착용시 동적 동작자세에서는 뛰기, 중량물 20 kg 허리까지 들어올리기, 중량물 20 kg 들어 1 m 옮기기, 들것 들고 앞으로 걷기, 들것들고 뒤로 걷기의 동작들이 낮게 나타났으며 통계적으로도 유의하게 낮은 결과를 보였다(p < .001).

경상북도 북부지역의 임야화재에 대한 방재대책

방창훈 慶北專門大學(영주경상전문대학) 1997 慶北專門大學 論文集 Vol.16 No.-

앞에서 살펴 본 바와 같이 임야화재의 특성은 다른 화재와는 달리 주위환경의 영향을 많이 받고, 한 번 발생한 화재의 피해가 엄청나기 때문에 근본적인 예방활동이 우선되어야 한다. 그리고 발생한 화재에 대해서는 화재초기에 진화하여야 하며, 효율적인 활동을 위하여 전반적인 방재대책이 수립되어야 할 것이다. 육림, 조림은 산림청에서 임야화재에 대한 전담수습기관은 소방국이 담당하는 것에 일장일단이 있겠지만 가장 중요한 것은 궁극적으로 후손에게 전해 줄 우리 모두의 재산임을 인지해야 한다는 것이다.

대구시민의 소방안전의식에 관한 연구

방창훈,최영상 한국화재소방학회 2004 한국화재소방학회논문지 Vol.18 No.3

The purpose of this study is to supply basis data that can improve the recognition of Daegu citizens on fire safety through the investigation of their recognition on fire safety. To achieve the purpose, 553 Daegu citizens in Daegu city were interviewed from Oct. 2 to 15, 2003. The results of this study are as follows; Citizens had thought little the recognition of our society on fire safety and Daegu subway fire accident caused very big effect in citizens' fire safety recognition. Citizens did not trust about fire fighting facilities that is established in the building. Method to elevate recognition for citizens' fire safety recognition appeared by TV, newspaper, etc public information reinforcement (30.7%), establishment and operation of the fire safety experience center (24.6%), fire safety education reinforcement in school (20.8%). 본 연구는 대구시민의 소방안전에 관한 의식을 조사하여 시민들의 소방안전의식을 향상시킬 수 있는 기 본자료를 제공하기 위하여 수행되었다. 설문조사는 대구 시민 553명에 대하여 2003년 10월 2일부터 15일 까지 실시되었으며, 다음과 같은 결론을 얻었다. 대구시민들은 우리사회의 소방안전의식을 낮게 생각하고 있으며, 대구 지하철 화재사고가 시민들의 소방안전의식에 아주 큰 영향을 끼친 것으로 나타났다. 대구 시 민들은 건물에 설치된 소방설비에 대하여 신뢰하지 못하는 것으로 나타났다. 일반시민들의 소방안전에 대 한 의식을 높이기 위한 방법으로는 TV, 신문 등 언론홍보강화(30.7%), 소방안전체험관 설치 및 운영 (24.6%), 학교에서의 소방안전교육 강화(20.8%)의 순으로 나타났다.

방창훈,권진순,예용택 한국안전학회 2004 한국안전학회지 Vol.19 No.3

The objective of the present work is to examine evaporation cooling of droplet due to surface roughness under radiative heat input condition. The surface temperatures varied from 80~160℃ on aluminum alloy (AL 2024) and surface roughness was 0.18μm, 1.36μm. The results are as follows; Regardless of surface roughness under radiative heat input condition, as droplet diameter is larger, the in-depth temperature of solid decreases and evaporation time increases. In the case of 0.18μm and 1.36μm of surface roughness, the larger the surface roughness is, the less the evaporation time is and the larger the temperature within the solid is. In the case of Ra = 0.18μm, evaporation time and time averaged heat flux for radiative heat input case is shorter than for the conductive case.
