To improve research productivity, it is important to acquire up-to-date information quickly. To this end, researchers seek information resources through various channels and methods and utilize them in their research and development processes. The Korea Institute of Science and Technology Information (KISTI) has developed a platform for integrated scientific and scientific information service called ScienceOn to provide specialized information, infrastructure resources, industry and technology analysis resources in one place to support the research and information ecosystem. Through this process, accessibility and usability are enhanced through the connection and convergence of various information and services. In this study, we look at recent R&D trends in scientific technology academic information integration services and recommended packaging services that can be utilized in batches according to the purpose of use. We look forward to improving national R&D productivity by strengthening the linkage and convergence of scientific and technological information.

Research Institutes of Government has produced various information about research, seminar, recent research trend, and so on. This information flows into project management organization and institute management organization. It is necessary to connect information systems of these organizations and institutes. The existing systems connect with self-defined protocol between the organizations and the institutes or HTML parsing method. but, these methods have many drawback for expanding and changing problem. This paper designs and implements science and technology information connection system using RSS.

Recently, BIM has attracted attention as a technology to improve the construction productivity. The BIM standards to be applied to the BIM project are necessary for using or connecting the current 2D-based drawing standards. To develop the standard for BIM-based QTO and cost, this paper focused on using QDBEx, which was applied to road project cost management and connecting QDBEx with IFC, which is the BIM data delivery format. The IFC schema was evaluated to determine if it is possible to use the converts to the QDBEx XML file. As a result, 66% of the whole was available to connect directly, and 17% was available to connect through the processing of instance. The remaining 17% was evaluated to determine if it was available to connect. In the future, improvements in the schema will be suggested based on these results.

This study proposes MF (Model Filter)-based M-BDL (MF-based BIM Data Linkage), which is a model filter-based data mapping method for BIM (Building Information Modeling)-BEMS linkage. Recently, BEMS (Building Energy Management System) is actively utilizing 3D spatial information. This allows the user to intuitively manage the facility energy linked to spatial information. To use BIM data in energy management systems, it is essential to link BEMS with BIM data only in terms of the user requirements. On the other hand, if the BIM is a rich dataset and is linked as it is, the user will need to manage the unnecessary information. By mapping only the data required for BEMS in heavy BIM data through M-BDL, the BIM data can be lightened and the amount of data required for maintenance can be reduced. This technology proposes a mapping method that can link the BIM data with the filtered BIM data.

This study analyzed the linkage relations of technological innovation between Daedeok Innopolis and other seven innovative clusters in industrial complexes which have played important roles as innovative centers in Korea. To begin with, we selected major technologies of Daedeok Innopolis for which the linkage with other clusters of innovative activities was analyzed quantitatively and graphically with association matrices, network analysis and dendrogram. Based on this network analysis, we analyzed the technological linkage among clusters and found the direction and strength of technological cooperation of the Daedeok Innopolis with other innovative clusters by technology field. This study analyzed the technological network between the Daedeok Innopolis and other clusters on 6 technology fields in which Daedeok has innovative capabilities. In the analysis was measured the centrality of Daedeok compared with that of other clusters in areas where Daedeok is relatively active in innovative activities. As a result, Daedeok showed the highest centrality with the active innovative activities. Except Daedeok, Banwol-Sihwa cluster showed the highest centrality in all of the 6 technology fields. Putting all the centrality of each innovative cluster and the linkage relations of Daedeok Innopolis together, it need to consider the following policy directions to strengthen the innovative linkage with other clusters. In Daedeok's main technology areas, it needs to increase the regional linkage with the clusters with relatively high centrality and relatively low linkage with Daedeok. For Changwon, Wonju and Gunsan with which Daedeok has the relatively low innovative linkage, it need to examine a new policy to improve the linkage with technologies related with the industry other clusters are nurturing. When Daedeok formulates a plan to cooperate with other clusters, it does not only have to consider the linkage relations of technological innovation analyzed in this study and but also has to examine the cooperative strategies from the comprehensive point of view considering every aspect of their strategic industries, supportive policies, industrial base and competitiveness. This study analyzed the linkage relations between regions based on the network analysis of patents only by co-invention. Consequently, it did not examine the factors inducing the co-invention, which is a limitation of the study and is to be investigated in the future. Also, the exploratory analysis on determinants of linkage intensity and the strategies to get synergy effects through solidified linkage will be the issues of further study.

Recently, with the development of the 4th Industrial Revolution era and the popularization of technologies the maker movement is spreading worldwide in various ways for education, entrepreneurship, and solving social problems. This paper introduces a case of establishing and operating a maker space in Tanzania, East Africa, one of the developing countries. iTEC Tech-shop was established in the first half of 2018 at the Nelson Mandela African Institution of Science and Technology (NM-AIST) in Arusha, Tanzania by Innovative Technology and Energy Center (iTEC), and has been operating for nearly two years. With the allocation of empty warehouse space from NM-AIST, physical facilities were established through the purchase and installation of equipment and hand tools. Based on the advice from Idea Factory of Seoul National University and Fab-Lab Seoul, iTEC Tech-shop operational system were established. Through a total of 7 technical workshops, iTEC Tech-shop provided training courses for about 180 local personnel. In addition, the smart Techshop test-bed project was promoted in order to improve the operation level along with securing sustainability of the Techshop. The case of the iTEC Tech-shop could be a useful case for institutions or organizations promoting the maker movement to developing countries.

기후변화로 태풍, 집중호우 등의 발생빈도가 높아져 도시지역에서 홍수범람으로 인한 인명피해와 재산상의 손실이 반복되고 있으며, 이로 인한 사회기반시설에 대한 피해가 급증하고 있다. 따라서 이를 효과적으로 방어할 수 있는 구조적, 비구조적 내배수 홍수방어 대책의 수립이 시급한 실정이다. 도시유역에서의 침수피해는 내부배제 불량에 따른 내수침수가 대부분을 차지하고 있으며 효과적인 내수침수예측 및 홍수피해 저감을 위한 방재시스템 구축을 위해서는 내외수를 연계한 침수 예측 선진화 기술개발이 필요하다. 따라서 본 섹션에서는 레이더 및 위성 정보를 활용한 초단기 또는 단기 강우예측 기술개발, 하수관망 단순화 자동화 기술 개발, 베이지안 모형과 연계한 SWMM모형의 매개변수최적화, 내수침수 대응을 위한 동적의사결정 모형 등의 핵심기술을 통합한 내외수를 연계한 도시홍수예보시스템 개발내용과 실강우사상에 대한 적용성 검토 결과를 소개하고자 한다. 본 연구의 성과는 실시간 또는 예측강우분석을 통하여 돌발홍수로 인한 내수침수피해에 대한 골들타임을 확보하고 대피지구 선정 및 주민의 대피이동 정보제공 등 도시홍수로부터 발생하는 피해에 대한 최적화된 선제적 대응체계 구축에 활용도가 높을 것으로 기대된다.

자율운항선박은 센서, IoT, 빅데이터, AI, 플랫폼 등 고도의 ICT 요소 기술이 필요한 미래 유망 산업 분야이다. 특히 선박 내부장치로 부터 수집된 정보와 선박 주변의 해상 데이터가 증가될수록 선박 대 선박 및 선박 대 육상 간 정보 교환 체계인 해상통신망의 중요성은 커질수 밖에 없다. 해양수산부는 2020년 세계 최초로 대한민국 연안으로부터 최대 100km 까지 해역을 LTE(Long Term Evolution) 통신체계로 구축한 바 있다. 본 논문은 초고속 해상무선통신망(LTE-Maritime)이 자율운항선박의 주요 통신 기술로써 활용되기 위해 우선적으로 고려할 사항을 타 해상 무선통신 기술과의 연계, 업링크 및 항내 통신품질의 향상 관점으로 살펴보고자 한다. 이를 위해 LTE-M. 망의 무선설비 다각화 사업으로 추진중인 해양 드론용 송수신기의 실해역 성능 시험을 통해, 선박과 육상 간 정보 교환에 있어 상호운용성 시험의 중요성을 재고해 보고, 해상 무선통신 체계의 신뢰성 및 호환성을 확보하기 위한 무선품질지표, 상호운용성 시험 방법 등을 제시하고자 한다.

지식기반 사회가 도래하여 기술혁신이 가속화되고, 글로벌 경쟁이 심화됨에 따라 과학기술 R&D 수행에 선행기술 분석의 중요성이 증대하고 있다. 논문과 특허는 이 작업에 있어서 특허 단독으로는 학술 문헌으로 얻어진 기술 정보가 시장 관점에서 어떻게 활용될 수 있는가를 검증하는데 이용될 수 있다는 점에서 의미가 있지만 분류체계 및 데이터 특성이 다른 논문과 특허를 연계하는 연구는 또 다른 이슈와 가치를 지니며, 아직까지 국내 연구가 부족한 상황이다. 따라서 본 연구에서는 상호 주제 해석이 불가능한 논문과 특허의 분류체계를 일원화할 수 있는 매핑 테이블을 생성해서 두 유형의 문서가 상호 연계가 가능한 환경을 만들고자 한다.
