건설 엔지니어링은 과학기술과 지식을 접목하여 고부가가치와 일자리를 창출하는 대표적인 산업이지만 그 중요성이 저평가 되고 있다. 국토교통부의 자료에 의하면 엔지니어링 산업의 부가가치율(65.3 %)과 고용유발계수(14명 고용/10억 원)은 제조업의 3배 이상이다. 특히 시공 이전의 프로젝트 관리·기본설계 등 전방가치사슬은 총사업비의 10~15 % 미만임에도 불구하고 인프라 시설의 전체 가격과 품질을 좌우한다. 본 연구에서는 인프라 엔지니어링 플랫폼을 프로젝트 단위가 아니라 엔터프라이즈 수준의 플랫폼으로 개발하기 위하여 필요한 프레임워크, 도로 설계 업무 분류, 설계 지원 모듈 및 데이터베이스 구축 방향에 대하여 제시하고, 이를 바탕으로 클라우드 기반의 설계 플랫폼의 초기 버전을 개발하였다. 개발된 설계 플랫폼은 시간/공간 제약 없는 웹 기반 설계 업무환경을 제공하고, 해외사업 수주 및 경쟁력 확보에 크게 기여할 수 있을 것으로 기대된다.

In this research, we create a network infrastructure based on a service-oriented infrastructure (SOI) for the virtualization technology and integrate it with a cloud technology that applies the cloud integration management platform (CIMP) concept. In CIMP, the server and storage will be separated. The server will be adopted for virtualization while the storage will be used by students and teachers to store data. As long they save their data in the storage module, every time, everywhere, and on every device, they can access their data. This research will implement the design of the network infrastructure and be applied to the remote practical learning system in the laboratory. Students and teachers will ultimately adopt this network infrastructure for remote practice using their respective devices without physically meeting in the laboratory. In the future, if the implementation phase is successful, then in addition to laboratory environments, it can be implemented in all learning activities at our campus.

기존의 고정 단말기(PC)에서만 주로 행해지던 각종 다중 사용자 접속 온라인 응용이 최근 모바일 단말기의 급속한 확산으로 기존 PC와 PDA, 휴대폰 등이 공동 작업을 수행하는 멀티 플랫폼 기반 온라인 응용으로 전환되고 있다. 이 논문에서는 멀티 플랫폼 기반 네트워크 응용을 위한 기반 구조를 제안하였다. 그리고 다양한 클라이언트의 프로세서 처리 능력과 통신 속도의 비대칭이라는 멀티 플랫폼 응용의 특징을 고려한 중복 일관성 제어 기법, 다양한 클라이언트간의 변경 전파 프로토콜을 제안하였다. 그리고 멀티 플랫폼 기반 채팅 프로그램을 제작하여 제안한 구조 및 기법들이 적절히 동작함을 보였다.

The issues were studied of an open-source scaling drone imagery platform, called WebODM. It is known that processing drone images has a high demand for resources because of many preprocessing and post-processing steps involved in image loading, orthophoto, georeferencing, texturing, meshing, and other procedures. By default, WebODM allocates one node for processing. We explored methods to expand the platform's capability to handle many processing requests, which should be beneficial to platform designers. Our primary objective was to enhance WebODM's performance to support concurrent users through the use of container technology. We modified the original process to scale the task vertically and horizontally utilizing the Kubernetes cluster. The effectiveness of the scaling approaches enabled handling more concurrent users. The response time per active thread and the number of responses per second were measured. Compared to the original WebODM, our modified version sometimes had a longer response time by 1.9%. Nonetheless, the processing throughput was improved by up to 101% over the original WebODM's with some differences in the drone image processing results. Finally, we discussed the integration with the infrastructure as code to automate the scaling is discussed.

We have developed an information management tool for the EDISON (EDucation-research Integration through Simulation On the Net) open platform. EDISON is, at present, a web-based simulation service for education and research in five computational areas, namely, nanophysics, fluid dynamics, chemistry, structural dynamics, and computer aided optimal design. The EDISON open platform consists of three tiers: EDISON application framework, EDISON middleware, and EDISON infra-resources. The platform provides web portals for education and research in areas such as computational fluid dynamics, computational chemistry, computational nanophysics, computational structural dynamics, and computer aided optimal design along with user service. The main purpose of this research is to test the behavior of the release version of the EDISON Open-Platform under normal operating conditions. This management tool has been implemented using the RESTful API designed in EDISON middleware. The intention is to check co-operation between the middleware and the infrastructure. Suggested tools include User management, Simulation and Job management, and Simulation software (i.e., solver) testing. Finally, it is considered meaningful to develop a management tool that is not supported in other web-based online simulation services.

The Republic of Korea developed a national project to construct a new administrative capital, Sejong city and to relocate administrative organizations of the central government for improvement of overpopulated capital, Seoul and regional balanced development. By the way, to relocate the central administrative organizations was not a sufficient condition for the sustainable development of the city. An industrial infrastructure development has been tried to attract universities, enterprises and research institutions in the region as a demand for internal growth power of the city was increased. In addtion, a basis for regional endogenous growth through projects to establish innovation system based on industry-academia cooperation was prepared as well. This paper reviews the major contents of the development plans for Tech-Valley project and looks into major introductory functions, characterization plans, strategies for fostering strategic industry, cooperation system of the inside and outside the region, and a strategy for building innovation platform. This case can be regarded as a significance of constructing technology infrastructure for the sustainable growth by preparing foundation for establishing innovation system and a cluster based on this system in the process of building and developing new city which did not have any industrial platform in the region.

In the age of Web 3.0, the metaverse is emerging as a new innovative element to replace the Internet. Leading major ICT companies, it is striving to become a metaverse platform or infrastructure-oriented company. Along with the expansion of the VR and AR market, governments of each country are investing large budgets in this field. However, security concerns about metaverse are also growing. In addition to potential damage to infrastructure, platform and services, personal information leakage and privacy damage are expected to increase further. In this study, we investigated and closely analyzed cases of infringement on the infrastructure, platform, and service of Metaverse. We have clearly identified the current state of metaverse security and the characteristics of the risks of greatest concern. The research procedure is composed of a method of determining the metaverse security area for case analysis first and deriving the type of threat by area through the type of infringement. In particular, the results were mapped into Domain, Case, and Threat, and the implications of the results were analyzed. Through these results, researchers want to contribute to finding the right direction of research by clearly understanding the latest metaverse security status.

Generally, because individual agricultural product possesses its own distinctive characteristics and shows different characteristics at each stage of the agricultural supply chain, it is necessary to develop a proper enterprise architecture for managing information system. In this paper, we propose an enterprise architecture based on RFID/USN technology that can be used as a reference enterprise architecture for u-IT application in the agriculture sectors, which is called the u-Farm enterprise architecture with taking heterogeneous characteristics of agricultural products into account for. In addition, we also developed the RFID/USN middleware platform as a core infrastructure technology. Fo evaluation of the performance of the proposed u-Farm architecture and the RFID/USN middleware platform, the field-trial evaluation at the apple Agricultural Processing Center (APC) has been executed and the results shows that the proposed architecture and platform perform well in terms of information integration over the whole SCM process from the farming stage to delivering statge to the customers. It is expected that the proposed u-Farm enterprise architecture can be utilized as a standard information architecture, and the RFID/USN middleware platform can be a infrastructure platform for future u-IT based information technology applications and services in the agricultural environment.

그동안 행해진 중앙 집중형의 지식 창고(Knowledge Repository)에 분산된 지식을 모으는 방식만으로는 개인의 역량 및 조직의 경쟁력 강화라는 지식 관리의 본질적 목표에 달성하기 어렵다. 지속가능한 지식 생태계를 구축하기 위해서는 독립적인 지식 생산이 아닌 교류와 협력을 통한 지식 생산으로 확대되어야 하며, 이를 통해 유의미하고 고부가가치의 지식 자원을 생산할 수 있어야 한다. 이에 본 연구는 과학기술 지식자원을 저장하고 개방·공유·활용을 통해 지식을 재생산하고 진화시키는 통합서비스 플랫폼을 설계하는 것을 목표로 한다. 설계된 플랫폼은 그 우수성을 평가하기 위해, 계획 수립의 적정성, 플랫폼의 효과성, 플랫폼의 효율성, 로드맵의 적정성 항목들로 분류된 세부 항목들에 대해 평가를 수행하였으며, 상기 4개 평가 항목에 대해 평균 95.56점을 받았다.
