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.

As construction projects get bigger and more complex, communication and information flow among participants become key success factors of a project. Accordingly, construction projects to respond to these changes being made in the introduction of BIM (Building Information Modeling). But as 2D drawings are still to be widely used in practical fields, it is very important that 2D drawing information could be easily and clearly projected from 3D BIM data. In this study suggest that efficiency of design phase in BIM-based construction projects for can cause confusion and additional work in traditional to BIM.

소프트웨어 획득부서에서는 정보체계획득 및 개발표준화를 위해 아키텍처 프레임워크와 CBD 방법론을 개발하여 정보체계의 상호운용성과 재사용성 확대를 통해 효율적인 통합 및 표준화 관리가 이루어지도록 하고 있다. 그러나 AF와 CBD 방법론간의 산출물 상호관계에 관한 명확한 가이드라인과 활용방안이 없는 실정이다. 이로 인해 산출물 중복작성 등으로 불필요한 개발기간 연장과 비용 중복 등 비효율적인 업무수행이 이루어지고 있다. 본 논문에서는 두 절차에서 요구산출물들의 연관관계 및 중복성을 분석하여 CBD 프로세스에 따라 AF 산출물의 재활용 방안을 제시해 봄으로써 산출물의 작성 부담을 경감시키고 내용에 충실하게 작성하도록 하여 산출물의 품질 및 재사용성을 높여 효율적인 정보체계를 구축하는데 도움이 되고자 한다.

A Web-based design automation system for concrete slab bridge has been developed to manage the resultant documents as well as to speed up the repetitive design process. Manipulation of engineering drawings in the Web page is one of the critical functions needed for Web-based design automation. Active Server Pages (ASP) is used to that collects design parameters in the database, and eXtensible Markup Language (XML) and XML-based vector graphics are expected to facilitate the representation of engineering drawings in the Web page. In this paper, we present how we used XML and Scalable Vector Graphics (SVG) to compose engineering drawings and represent them in the Web page. XML Data Island we designed to define drawing components turned out effective in manipulating the engineering drawings in the Web page.

These days construction management is executed in an information technology environment, which creates a large volume of digital data. At the completion of a project, the contractor is required to transfer to the owner the digital data as project deliverables usually in a form of CD's. From an enterprise-wide view point, this traditional way makes the management of project deliverables ineffective as the data accumulated from different projects could be enormous. The objective of this paper is to propose a structured way to utilize a XML database for better management of project deliverables. The XML database provides an environment which users can access through a project deliverable management system (PDMS). A pilot of the PDMS has been developed to test the effectiveness of document control. The result of the test demonstrates that the effectiveness of project deliverable management can be increased by providing a high transportability and usability of data in the construction life cycle.

연구노트는 연구자가 연구의 수행 시작에서부터 연구 성과물의 보고 및 발표 또는 지식 재산화에 이르기까지의 과정 및 결과를 기록한 자료를 의미한다. 소액 연구 사업 및 일반 기술 지원 사업 등 정책 및 관리, 지원을 목적으로 하는 연구 사업을 제외한 모든 연구 사업은 연구노트를 작성하도록 할 필요가 있다. 이때 주로 사용되는 방식은 제본된 노트에 필기구 등을 이용하여 내용을 기재하는 서면 연구노트이다. 많은 정부출연연구소들이 서면 연구노트를 제작 및 배포하고 있고, 작성된 연구노트에 대해 점검 결과에 따라 포상을 하는 등의 연구노트 작성을 독려하는 노력을 하고 있다. 그럼에도 불구하고, 반복되는 작업이라는 점과 기록하기 복잡하다는 점, 실험 중에 연구노트를 작성하기 어렵다는 점 등의 이유로 인해 서면 연구노트의 활용도는 매우 낮은 실정이다. 본 논문에서는 이러한 상황을 극복하기 위해 정부출연연구소에 적합한 전자연구노트 시스템 구축 사례에 대해 소개를 하고, 시스템 운용에 따른 효과를 분석해 보고자 한다.

This paper evaluated the safety and serviceability of a building structure considering the multi-hazard and proposed TMD-based adaptive smart control system to improve the structural performance. To make multi-hazard loads, an artificial earthquake and artificial wind loads were generated based on representative regions of strong seismicity and strong wind in U.S.A. The safety and serviceability of a 20-story example building structure were investigated using the generated artificial loads. A smart TMD was employed to improve the safety and serviceability of the example structure and its capacity of structural performance improvement was evaluated. The smart TMD was comprised of a MR (magnetorheological) damper. Numerical analysis showed that the example building structure could not satisfy the design limit of safety and serviceability with respect to multi-hazard. The smart TMD effectively reduced the seismic responses associated with the safety and wind-induce responses associated with serviceability.

The Ministry of National Defense has developed MND-AF and Defense-CBD methodology to make the integration and management of standardization effective through enhancing the interoperability and reusability of information systems. Yet no explicit guidelines or procedures have not been developed for the applying range and mutual relationship of the artifacts between MND-AF and Defense-CBD methodology. Thus, the development time is unnecessarily extended and budget also is increasing because both methodologies produce the artifacts respectively. This paper presents a reusability enhancement scheme for producing MND-AF artifacts according to Defense-CBD process by analyzing artifacts of two methodology les at each element level, so that it will reduce the overhead of producing the artifacts and enhance the completeness of the artifacts. In result, in the case of applying Defense-CBD methodology for developing a information system34 artifacts out of 37 MND-AF artifacts can be reusable.

MND(Ministry of National Defense) has developed MND AF(Ministry of National Defense Architecture Framework) and CADM(Core Architecture Data Model to guarantee interoperability among defense information systems. But, it is very difficult to manage architecture product documented through MND AF and CADM. So, there Is necessity for development of modeling tool and repository system which can develop architecture products and manage architecture product informations in common repository In this paper, we developed architecture product management system which supports development and management of meta model and architecture product of MND AF and CADM. Through architecture product management system architect of each agency can construct architecture product in a more effective and efficient way with modeling method and a user can search and refer useful architecture product informations using query function. Also, architecture product management system provides the basis for system integration and interoperability with integration, analysis and comparison of architecture product.

To product the map by terrestrial photogrammetry method, a few rather nuisance stereo image acquiring processing and plot using expensive analytical instruments have to be performed. In this study, plot was made by acquiring and rectification image using simple method rather than above it. For this, geometry rectification system was constructed for the generation of single ortho-image analysis. and these ortho-images of architecture were made and analysed by appling various warping methods. As a result, the performance of single image analysis could be estimated, and it is expected that the application of this is possible to various non-topographic photogrammetry.
