위성 영상과 관측 센서 데이터를 이용한 PM10농도 데이터의 시공간 해상도 향상 딥러닝 모델 설계
백창선,염재홍 한국측량학회 2019 한국측량학회지 Vol.37 No.6
PM10 concentration is a spatiotemporal phenomenta and capturing data for such continuous phenomena is a difficult task. This study designed a model that enhances spatiotemporal resolution of PM10 concentration levels using satellite imagery, atmospheric and meteorological sensor data, and multiple deep learning models. The designed deep learning model was trained using input data whose factors may affect concentration of PM10 such as meteorological conditions and land-use. Using this model, PM10 images having 15 minute temporal resolution and 30m×30m spatial resolution were produced with only atmospheric and meteorological data. PM10 농도는 시간 및 공간 의존성을 동시에 가지는 시공간 데이터이지만 현실적으로 연속적인 시공간 데이터를 획득하는 것은 쉬운 일이 아니다. 본 연구에서는 위성영상과 대기질 및 기상 관측 센서 데이터를 복합적인 딥러닝 모델에 적용하여 시공간 해상도를 향상시키는 모델을 설계하였다. 설계된 딥러닝 모델은 기상, 토지 이용 등 PM10 농도에 영향을 줄 수 있는 인자를 이용하여 학습하였으며, 대기질 및 기상 관측 데이터만을 이용하여 15분 단위의 30m×30m의 공간해상도를 PM10 영상을 생성하였다.

The rapid progress toward the 4th industrial society has led to possibilities of fire increase. It is pointed out that, though initial fire suppression is emphasized, the current legal systems do not sufficiently recognize the importance of initial fire suppression. In order to resolve this, problems of the current legal systems and regulations, as well as fire-fighting facilities to be equipped according to the size of specific fire-fighting objects, were diagnosed. Also, suggestions for improvement were provided through comparative analysis with relevant laws and technical regulations of Korea and other countries. According to fire safety standards such as NFPA, IMO, ISO, and Russian standards, automatic fire extinguishers are to be installed as per the adaptability criteria of fire extinguishers and automatic fire extinguishers. In Korea, the “Act on Fire Prevention and Installation, Maintenance, and Safety Control of Fire-fighting Systems“ cover the types and scope of fire fighting facilities that include specific fire protection objects, such as electric room, power room, and substation room. This study has identified that, in case of a place with a floor area of less than 300㎡, the installation requirement is not clearly specified. Therefore, in this study, fire extinguishing equipment and automatic fire extinguishing equipment to be added for each sub-use application are proved to have fire extinguishing performance of Class A, Class B, and Class C, respectively. In view of the fact that, in overseas standards, all space except containing such materials as Deep fire, metal fire and peroxide, can be installed with fire fighting equipment, a legal system for specifying the capacity units of fire fighting apparatus by application is, in this study, proposed.

This study is intended to provide legislative direction for fire products life expectancy. Domestic and international lawsrelating to fire products life expectancy have been reviewed, and the results of a Fire Safety Manager Consciousness(FSMC) survey were analyzed. The FSMC survey has been designed in order to assist with the establishment of appropriatefire safety policy. A questionnaire survey was conducted with 660 fire safety administrators from 17 municipal andprovincial districts, with the intention of gaining expertise on the extension of life-span for 32 fire products. The surveyalso asked for candidates opinions on future policy direction. Based on the survey results and the review of policies withinother nations, we have devised a set of policy issues with the intention of extending the life-span of fire-safety items. Thesurvey result revealed that 79.3% of Fire Safety Managers (FSMs) concurred with the establishment of legislation regardingthe maintenance and correct care of fire-safety products. Overall, over 30% of FSMs were in favor of regulationsregarding Ddry chemical fire extinguishers (77.3%), fire detectors (44.6%), fire hoses (44.4%), gaseous agent fire extinguisher(40.6%), automatic descending life lines (36.2%), exit lights (35.9%), air respirators (35.9%), extinguishing systemsfor residential cooking facilities (33.9%), automatic spray-type extinguishing units (33.9%), emergency lights(31.2%), and gas leakage detectors (30.7%). Especially, among these, dry chemical fire extinguishers (60.0%), detectors(20.0%), and fire hose (18.8%) were identified as the fire products primarily in need of maintenance legislation. The generalconsensus is that fire products older than 10 years need to be replaced. Based on the survey results, there was generalagreement that fire product life expectancy is in need of legislation. This study recommends the introduction of fire productlife expectancy legislation in phases. 본 연구는 국내외의 소방용품 내용연수 제도와 소방안전관리자 인식조사를 바탕으로 소방용품 내용연수 제도화에 대한 정책 방안을 제시할 목적으로 실행되었다. 이를 위하여 일본, 미국, 한국의 소방용품 내용연수 제도를 분석하여 권장내용연수를 도출하고, 전국 17개 시도권역 소방안전관리자 660명을 대상으로 소방용품 내용연수 제도화 필요성, 32종의소방용품의 내용연수 관리 및 향후 정책 방향에 대한 인식 조사 결과를 분석한 후 소방용품 내용연수 정책실행 방향을찾고자 하였다. 소방안전관리자 설문 조사 결과, 소방용품 법제도화에 대하여 79.3% 소방안전관리자가 찬성하였으며 소방용품 품목별 제도화 필요성에 대해서는 분말소화기(77.3%), 감지기(44.6%), 소방호스(44.4%), 가스계소화기(40.6%), 완강기(36.2%), 유도등(35.9%), 공기호흡기(35.9%), 주거용주방자동소화장치(33.9%), 자동확산소화장치(33.9%), 비상조명등(31.2%), 가스누설경보기(30.7%) 등이 30%를 상회 수준으로 내용연수 관리가 필요하고, 특히 분말소화기(60.0%), 감지기(20.0%), 소방호스(18.8%)는 최우선 도입이 필요하다고 인식하였으며, 소방용품 내용연수는 대부분 10년 전후 경과하면 교체해야 한다고 인식하고 있었다. 따라서 이러한 결과를 토대로 내용연수 제도화 소방용품 품목을 선정하고 단계적 정책 도입방안을 제안하였다.

주택 화재방지를 위한 주택용분전반용 자동소화장치 개발연구
백창선 국가유산방재학회 2022 문화재방재학회 논문집 Vol.7 No.3
It is a reality that it is difficult to extinguish a fire in the early stage because people do not reside in places where distributionboards for small houses are installed. In this study, in order to prevent property damag and human casualties in advance froma small fire, a new device is developed to implement and quickly extinguish the instantaneous fire that occurs in smalldistribution panels with a protection volume of less than 0.02 m3.
