Design quality in constructed project is a primary consideration to achieve overall project objectives. It is not easy to evaluate the design quality because various factors are involved in the design process. This paper presents a new approach to improve the evaluation process of design quality In the construction project The evaluation model is developed to satisfy the requirement for implementing the ISO 9000 Quality Assurance Standards in the design process. It is assumed that design changes are resulted from the poor management of design quality. The model relates design changes to design quality management items. It assigns weight ratio to each design quality item to evaluate quantitatively Design Quality Index (DQI) is calculated to assess design quality based on the Objectives Matrix. A case study is performed to illustrate the practical implementation of the design quality evaluation.

Today's dynamic nature of the construction environment requires management systems to be active enough to take real-time decisions. For real-time decision making, effective 3D spatial information acquisition is imperative. Various 3D data acquisition technologies are being developed and tested for 3D spatial information acquisition and its use for wide range of areas in the construction industry, however, there are shortcomings in these technologies. The major problems are long processing time and high cost which make current technologies impossible to be used for real-time applications. Laser-based Flash LADAR that illuminates the entire scene with diffuse laser light is comparatively fast and cost effective, therefore it is well suited for 3D spatial modeling of dynamic environment on a construction site. This paper presents experimental results to evaluate the performance of flash LADAR and discuss issues of applicability of Flash LADAR to 3D spatial modeling on a construction site.

This study suggests the necessity and domestic application plan a national authority database that promotes an integrated access, richer search, and understanding of historical information sources and archival resources distributed among cultural heritage institutions through the "Social Networks and Archive Context" project case. As the SNAC project was transformed into an international cooperative organization led by NARA, it was possible to secure a sustainable operating system and realize cooperative authority control. In addition, SNAC authority records have the characteristics of providing richer contextual information about life and history and social and intellectual network information compared to libraries. Through case analysis, First, like SNAC, a cooperative body led by the National Archives and having joint ownership of the National Library of Korea should lead the development and expand the scope of participating institutions. Second, in the cooperative method, take a structure in which divisions are made for each field with special strengths, but the main decision-making is made through the administrative team in which the two organizations participate. Third, development of scalable open source software that can collect technical information in various formats when constructing authority data, designing with the structure and elements of archival authority records, designing functions to control the quality of authority records, and building user-friendly interfaces and the need for a platform design reflecting content elements.

Sustainable Development(SD) is an important concept for the future of the coastal area, and for development of fishing villages. Since 1992 UN Conference on Environment and Development in Rio de Janeiro many governments and local authorities throughout the world have been engaged in preparing and implementing $\ulcorner$Agenda 21$\lrcorner$. Many projects which previously would have been identified as environmental protection are now presented under the banner of sustainable development. Integrated Coastal Management (ICM) is an extension of sustainable development. ICM was presented as a framework for resolution of coastal use conflicts. The aim of the present paper is to assess sustainable development potential of fishing villages in Cheonsu Bay Region according to implementation of ICM. Cheonsu Bay Region was known as one of the productive fishing grounds and Cheonsu Bay Region preserved unique characteristics of traditional fishing villages. But this region is now experiencing many changes through the massive reclamation projects like Seosan A B Project. After a brief overview of concepts and history of SD and ICM, the reclamation process and its impacts on both fishery and fishing communities in Cheonsu Bay Region are discussed. According to their changing environmental and socio-economic characteristics after the reclamation, ca 35 representative coastal villages in this region can be classified into 5 types. Many coastal villages shows diversity in their economic activities, as tourism and recreation function becomes more and more important in this region. In present-day Cheonsu Bay Region, it is possible to differentiate fishing village cooperatives(FVO) with high potential of sustainable fishery development, FVOs with medium potential, FVOs with low potential on the basis of 14 selected indicators.

The recent advancements in Smart City and Digital Twin technologies have highlighted the critical role of integrating GIS and BIM in urban planning and construction projects. This integration ensures the consistency and accuracy of information, facilitating smooth information exchange. However, achieving interoperability requires standardization and effective project integration management strategies. This study proposes interoperability solutions for the integration of GIS and BIM for managing various projects. The research involves an in-depth analysis of the IFC schema and data structures based on the latest IFC4 version and proposes methods to ensure the consistency of reference point coordinates and coordinate systems. The study was conducted by setting the EPSG:5186 coordinate system, used by the National Geographic Information Institute's digital topographic map, and applying virtual shift origin coordinates. Through BIMvision, the results of the shape and error check coordinates' movement in the BIM model were reviewed, confirming that the error check coordinates moved consistently with the reference point coordinates. Additionally, it was verified that even when the coordinate system was changed to EPSG:5179 used by Naver Map and road name addresses, or EPSG:5181 used by Kakao Map, the BIM model's shape and coordinates remained consistently unchanged. Notably, by inputting the EPSG code information into the IFC file, the potential for coordinate system interoperability between projects was confirmed. Therefore, this study presents an integrated and systematic management approach for information sharing, automation processes, enhanced collaboration, and sustainable development of GIS and BIM. This is expected to improve compatibility across various software platforms, enhancing information consistency and efficiency across multiple projects.

CAT(Catchment hydrologic cycle Analysis Tool)은 기존 개념적 매개변수 기반의 집중형 수문모형과 물리적 매개변수 기반의 분포형 수문모형의 장점을 최대한 집약하여, 도시유역 개발 전 후의 장 단기적인 물순환 변화 특성을 정량적으로 평가하고 물순환개선시설의 효과적인 설계를 지원하기 위한 물순환 해석 모형이다. CAT은 수문학적으로 균일하게 판단되는 범위를 소유역으로 분할하여 지형학적 요인에 의한 유출 특성을 객관적으로 반영할 수 있으며, 개발 공간 단위별로 침투, 증발, 지하수 흐름 등의 모의가 가능하도록 하는 Link-Node 형식으로 개발되었다. 모형의 UI(User Interface)는 사용자가 손쉽게 모형을 적용 관리하고, 여러 시나리오를 동시에 효과적으로 모의하여 분석할 수 있도록 설계되었다. 또한 모든 입력 출력 자료를 Excel이나 텍스트 형식과 연동되도록 하여 프로젝트별 매개변수 관리가 용이하도록 개발하였다. CAT의 수문해석모듈로 증발산, 침투, 유역 유출, 지하수 유거, 하도추적 등의 모듈을 개발하였다. 증발산은 기준 증발산을 외부에서 직접 입력하거나, Penman-Monteith 방법을 선택할 수 있으며, 침투는 토양의 수리전도도에 따른 연직방향 침투 및 사면방향 복귀류를 고려할 수 있다. 노드의 지하수 유거를 고려하여 기존 노드-링크 방식 모형의 장기 유출 해석시 제한점을 보완하였으며, 하도추적을 위해 Muskingum, Muskingum-Cunge, Kinematic wave 방법 등의 해석법을 제공하였다. CAT의 수문모듈을 이용하여 설마천 유역을 단일노드 및 멀티노드로 개념화하여 모의하였으며, 모의결과를 관측유량과 비교한 결과, 두 경우 적절한 범위내의 결과임을 확인할 수 있었다. CAT의 안정적인 수문해석 기능을 바탕으로 향후 물순환개선시설 모듈과의 결합을 통해 장기 물순환 해석에 광범위하게 활용될 수 있을 것으로 판단된다.

The purpose of this study is to prepare a plan for the development of an ecological audit program that can be applied to the elementary school curriculum for sustainability education. School ecological audits enable students or groups of students to identify and solve the school's environmental problems on their own, thereby fostering sustainable decision-making and attitudes. As a result of the study through literature research, an ecological audit project learning program applicable to the elementary school curriculum was developed. The developed program is aimed at 6th graders and is composed of 16 steps reflecting the procedural and ecological processes of the ecological audit. In order to settle the developed program in the school site and improve the school sustainability of the developed program, it is necessary to introduce a school environment management system that can periodically monitor the school environment, strengthen the capacity of school teachers, and provide a professional certification system outside the school. In addition, with this bottom-up policy-making system, students can expect to spread a sustainable school culture through environmental education activities.
