In this study, we established the process for collecting and utilizing video scripts of disaster site based on public-private partnerships. It is for the purpose of actively utilizing private capabilities in disaster management, and quickly sharing video scripts to identify field conditions. Based on the experience of actual operation of public-private partnerships system in the event of typhoon in 2019, we also derived implications for continuous operation of the process. Results are meaningful in that the government established the process for collecting and utilizing video scripts through public-private partnerships during the initial disaster response phase. And we also confirmed the possibility of spreading positive perception of disaster management organizations. However, there is a limit to the actualization and practical use of performance as an experimental pilot operation in the R&D stage. In addition, for continuous operation of the system, it is necessary to prepare institutional support measures such as organization, infrastructure for operating, programs of education and training, and policy making.

Disasters in South Korea are taking on more diverse and intricate aspects than before, while being affected by the industrial development and deterioration of the cities. Therefore, it is urgently needed for success in disaster countermeasures to secure emergency communications operating system which would make it possible to share various information between the control tower and field personnel quickly and accurately. This study proposes a method of improving the national emergency communications operating system based on the Federal disaster management system, emergency communications system, and Standard Operating Procedures (SOPs) employed in the US, which is the leading country in the field of disaster management. First, the organization of the emergency communications needs to be more systematized than in the past. The organization of the emergency communications of the central and local governments have to be administered according to their different roles and objectives. Furthermore, they must cooperate with each other based on interoperability. Second, emergency communications councils need to be established, composed of representatives related to disasters, and national and regional units need to be formed and operated separately. Third, the SOPs should not only cover both the operational and technical elements, but also assign the roles and responsibilities to the members of the disaster communications system. These improvements will assure the correct functioning of the disaster communications system in the field, which is expected to increase the probability of success in disaster countermeasures.

With the development of the information communication industry, the size of the communication device has been reduced to a system that generates a large amount of heat. Therefore, since the amount of heat generated by the wireless equipment is large in the wireless base station, the energy consumption is continuously consumed and the failure of the wireless base station may occur. Therefore, in this study, The study was analyzed. As a research method, we performed base station with a lot of calorific value and electric charge. We selected 25 base stations and obtained data for two weeks. To ensure reliability, the room temperature was kept constant at $27^{\circ}C$, and the control system was installed and equiped for two weeks to obtain the date analysis. In order to calculate the test results in the study method, the instrument was used with a computer, a digital thermometer, and dust measurement. For the date analysis, we conducted a research study on 25 wireless basestations before and after the installation of Control Sysetm.

(주)경동나비엔은 1978년 3월에 설립된 우리나라의 대표적인 보일러 생산 업체로 1979년 송탄공장에서 국내 최초 콤팩트형 사각 기름보일러 '코로나 KDB-202'를 출시하면서 업계의 주목을 받기 시작했다. 또한 최근에는 북경, 상해, 미국 등으로 진출하며 명실 공히 글로벌 기업으로 비상하고 있다. 이 같은 화려한 회사소개를 차치하고서라도 (주)경동나비엔을 모르는 사람이 없을 것이다. (주)경동나비엔은 옛 사명인 '경동보일러'로 1990년대 초 중반 '아버님 댁에 보일러 놔드려야겠어요'라는 광고를 통해 대대적으로 브랜드를 알렸기 때문이다. 이후 2006년에는 경동나비엔으로 사명을 변경하고 온수기 난방, 냉방 공조, 홈네트워크 각방제어시스템으로 사업 영역을 확장하고, 콘덴싱 기술력으로 해외 1억 달러의 수출액을 달성하는 등 국내 보일러 업계의 선두를 유지하고 있다. 이러한 (주)경동나비엔은 사업장의 안전관리에 있어서도 남다른 두각을 드러내고 있다. 대규모 기계공장을 운영하고 있는 만큼 이에 대한 안전관리 기술과 노하우도 남다른 것이다. 이번호에서는 (주)경동나비엔의 안전보건을 책임지고 있는 최종숙 주임을 만나 구체적인 업무내용과 안전에 대한 소견을 들어본다.

Recently use of renewable energies such as geothermal energy for space heating and cooling is increasing in Korea due to energy crisis and global warming. Ground source heat pump (GSHP) is known as one of the most environment-friendly HVAC (heating, ventilation and air-conditioning) systems in the world. However, some potential effects caused installation and operation of the GSHP systems on soil and groundwater environment are reported. The potential effects are closely related with inappropriate installation, operation and closure of the GSHP systems. In this paper, possible effects of the GSHPs on soil and groundwater environments are reviewed.

최근 애플망고 스마트 농가에 에너지 사용량이 증가됨에 따라 에너지 절감을 위한 대책들과 화석연료를 대체하는 다양한 신재생에너지 도입에 대한 요구들이 늘고있다. 본 연구에서는 애플망고 스마트 농가에 여러 에너지원들을 혼합하여 사용할 수 있도록 실증시험 모델을 구축하고 운영함으로써 그 효용성을 검토하고자 하였다. 우선 애플망고 특성을 고려한 비닐온실의 최대 냉난방부하량과 에너지모델을 분석하여 신재생 에너지원들의 혼합 및 기존 공조설비와의 연계를 계산하였다. 애플망고 시험 농지로는 재배에 적합한 제주도 서귀포를 선정하였으며, 기존의 경유 난방기를 사용하는 비교시험 하우스, 기존의 경유와 태양광, 지하 공기 히트펌프 난방기를 혼합하여 사용하는 실증시험 하우스, 경유와 지하공기 히트펌프 난방기를 사용하는 대조시험 하우스를 10~11월 두 달간 운영하여 그 결과들을 평가하였다. 온실 내외부에 온도, 습도, CO2를 측정할 수 있는 6점의 센서부들을 설치하였고, 적산 전력계와 유량계를 설치하여 데이터를 수집하였으며, 모든 시험 데이터는 모바일 원격으로 제어 및 모니터링이 가능하도록 구성하였다. 시험 결과, 각 하우스들에서 수확한 과실의 수량과 품질은 유사하게 평가되었지만, 실증시험 하우스의 난방비가 비교시험 하우스보다 절감되었다. 하지만 실증시험 하우스의 경우 높은 시설유지비로 인해 이를 고려한 사용료는 비교시험 하우스보다 더 비싸게 평가되었다. 본 연구를 통해 생산된 잉여전력을 매전할 때 이로 인한 이용비는 비교시험 하우스보다 더 경제적임을 확인할 수 있었다. 또한 기존의 경유와 지하공기 히트펌프 난방기를 혼합한 대조시험 하우스의 난방비용이 경제성에서 더 유리함을 알 수 있었다. 따라서 본 연구를 통해 애플망고 스마트 농가에 적합한 에너지-믹스 모델을 구축할 수 있었으며, 다양한 신재생에너지들의 효용성들을 검토할 수 있었다.
