Korea has established an advanced infrastructure for real-time precise positioning such as CORS, virtual reference station service and perform continuous upgrading. However, in order to utilize the national infrastructure, it is necessary to process the acquired spatial information and take many steps to derive the final product. In addition, this process is highly dependent on foreign software. In this study, GNSS field survey system was developed and evaluation of its usability was performed. Real-time GNSS field survey system was developed and the system improves user̓s convenience and usability. The system was able to conduct survey effectively and produce the results. In addition, we compare the existing software with the survey performance to show the availability of the real-time GNSS surveying system. The system developed through the research can perform all the functions from real-time survey to the production of the outputs. It can create economical added value of the foreign software as a whole and simplify the work required for post-survey performance.

홍수(洪水, Flood)에 대한 사람들의 인식은? 자고로, 홍수란 재해를 유발하는 반갑지 않은 가장 큰 자연현상 가운데 하나이다. 당하고 보면 홍수는 없었으면 좋겠다(라고 생각하는 사람도 적지 않겠지!). 그렇다면, 과거에는 홍수재해에 대한 대비책을 어떻게 세워왔으며(고대사회), 근현대의 우리세대는 고대사회의 대비책과 무엇이 어떻게 달라졌으며 과연 앞으로는 홍수재해를 어떻게 대비해 나갈 것인가? 결론은 첫째, 홍수발생의 수문학적요인과 기상예보의첨단기술을 개발해야 할 것이며, 둘째, 물 부족량 해결과 홍수재해조절을 다목적 댐건설로 추진해야 할 것이며, 셋째, 홍수량 소통로인 하천에 과부하가 걸리지 않도록 보다 큰 공간을 조성해야 하며, 넷째, 이상의 목적달성을 위하여 방재기술의 연구개발이 지속되어야하고 사회적으로 방재인프라가 구축되어야 한다.

국토교통부(장관 서승환)는 녹색건축물조성지원법의 후속조치로 지난해 12월 31일 제1차 녹색건축물 기본계획을 발표했다. 정부는 기본계획에 따라 2020년까지 건축물에서 배출되는 온실가스를 배출전망치(BAU) 대비 26.9% 감축 목표를 수립했다. 특히 정부는 녹색건축물의 보급과 육성을 비전으로 ${triangle}$신축 건축물의 에너지 기준 강화 ${triangle}$기존 건축물의 에너지 효율개선 촉진 ${triangle}$건축물 사용자의 에너지 절약 유도 ${triangle}$녹색건축 기술개발 및 인프라 구축 등 4대 추진전략과 10개 정책과제를 도출했다. 이번 녹색건축물조성지원법 수립을 통해 고효율 설비 의무화 등 기계설비를 확대 반영하여 기계설비업계 발전의 토대가 마련됐다. 향후 정책과제 추진에 따라 녹색건축 설비 및 시공품질 강화, 그린리모델링 활성화, 녹색건축 전문기업 및 전문인력 육성을 비롯한 기계설비분야 기술개발 촉진 등으로 구체화될 전망이다.

The total container throughput of ASEAN is expected to increase continuously with economic development. However, ASEAN port infrastructure is insufficient to handle the increasing trade volume. According to the World Economic Forum, ASEAN ports except Singapore and Malaysia are ranked in low. Participation in ASEAN port development projects can lead an increase in trade efficiency with S. Korea by improving the port infrastructure of ASEAN countries. In addition, the S. Korean port-related industry can be energized through entering ASEAN port development projects. This study, which measures the efficiency of ASEAN ports, can be used as a basic guideline for the development and the planning of the ports. This study used Data Envelopment Analysis(DEA) and Shannon's Entropy model together to measure ASEAN ports' efficiency. After measuring each DEA (CCR, I-BCC, O-BCC, SBM) weight, the efficiency of ASEAN ports is measured as reflecting each DEA weight. As a result, the ports of Singapore and Malaysia, the major ports in the world, have the highest efficiency. Further, Vietnamese ports need to raise efficiency along with increasing container throughput. Leam Chabang (Thailand), Ho Chi Minh City (Vietnam), and Tanjung Priok (Indonesia) exhibit a negative correlation between container throughput and efficiency; therefore, the ports need to improve so as to maintain competitiveness. Lastly, Cambodia, Myanmar, and Brunei, which do not have active economic development, need to improve their ports for economic development.

지난 8월 31일부터 9월 2일까지 대전 엑스포 대전무역전시관에서 "깨끗한 환경과 안전한 축산물"이란 주제로 열렸다. 3일간 열린 박람회 기간동안 14만 여명의 관람객을 유치하여 중부권에서 개최한 박람회로 지리적 효과를 충분히 발휘했고 전반적으로 성공적인 박람회라는 평가 했으나 전시시설 및 대중교통 연계, 숙박시설 인프라 부족, 해외 바이어 서비스 부문에서 개선되어야 할 과제로 남게 되었다.

The condition of infrastructure deteriorates as the service life increases. Since most infrastructure in South Korea were intensively built during the period of economic growth, the proportion of outdated infrastructure is rapidly increasing now. Aging of such infrastructure can lead to safety accidents and even human casualties. To prevent these issues in advance, periodic and accurate inspection is essential. For this reason, the need for research to detect various types of damage using computer vision and deep learning is increasingly required in the field of remotely controlled or autonomous inspection. To this end, this study proposed a neural network structure that can detect concrete damage by classifying it into three types. In particular, the proposed neural network can detect them more accurately through a hierarchical learning technique. This neural network was trained with 2,026 damage images and tested with 508 damage images. As a result, we completed an algorithm with average mean intersection over union of 67.04% and F1 score of 52.65%. It is expected that the proposed damage detection algorithm could apply to accurate facility condition diagnosis in the near future.
