  • 건설생산성의 혁신적 향상을 지향하는 린건설(Lean Construction) 구현을 위해 가장 시급히 개선되어야 할 사항은 건설생산 프로세스의 개선과 건설정보의 신뢰성 향상으로 정의될 수 있다. 본 연구에서는 건설생산 프로세스 중 설계/시공단계에서의 개선사항을 설계관리, 자재조달관리, 공정관리 측면에서 도출하고, 각 단계에서 도출된 개선사항을 웹기반 정보시스템으로 실현하여 건설산업 종사자들에게 필요한 정보와 지식을 제공하고자 웹 기반 분산형 건설정보 시스템을 개발하고자 한다. 이를 위해 건설생산 프로세스 각 단계에서의 주요 문제점을 파악하여 개선모델 및 요소기술을 제시하고, 모델의 구현을 위한 시스템 프로토타입을 개발하였다. 설계/자재조달/공정 관리지원 시스템은 웹 기반의 지식관리 시스템을 중심으로의 통합을 추진할 예정이다.

  • 컴퓨터를 활용한 지식과 정보 처리를 위해 온톨로지를 구축하고 활용하기 위한 연구가 이루어지고 있다. 그러나 현재까지의 온톨로지 개발 방법 및 온톨로지 구축 도구는 온톨로지 개발 목적에 따라 제한적인 부분에서 연구되어 사용되고 있다. 그러므로 개발하려는 온톨로지 특성에 따른 적절한 온톨로지 구축 프로세스와 도구가 필요하다. 본 논문에서는 특정 분야의 비전문가가 언어 자원으로부터 지식을 개념화하고, 개념을 형식화하여 온톨로지를 구축할 수 있는 온톨로지 구축 프로세스(OntoProcess)를 제안한다. 그리고 다수의 온톨로지 구축자가 동시에 온톨로지 구축 작업을 행할 경우 i)지식의 개념화 과정에서 동일한 개념을 중복 정의하거나 ii)개념의 형식화 과정에서 형식언어와 포구사용법의 이해 부족으로 인해 온톨로지 구축 능률이 저하되는 문제가 발생할 수 있다. 이런 문제를 해결하기 위해 메타 온톨로지를 이용한 다중 온톨로지 구축 프로세스(OntoProcess)를 제안한다. 제안한 프로세스에 기반한 온톨로지 구축 시스템 (OntoProcess)을 개발하고, 실제 온톨로지 구축 실험을 통하여 제안한 프로세스와 시스템의 효율성을 확인한다. 그리고 온톨로지 구축 과정에서 발견된 문제점 및 이에 대한 해결 방안을 제시한다.

  • "측정할 수 없는 것은 관리할 수 없다"는 말은 성과측정 시스템의 중요성을 잘 나타내 주는 말이다. 또한 이처럼 어려움을 나타내는 표현도 없다. 기업의 유형자산은 재무제표나 손익계산서 등의 구체적인 금액으로 측정이 가능하나 기업의 무형자산에 대한 가치측정은 많은 방법들이 도입되어 왔지만 어느 하나도 객관적인 틀을 제시하지 못하고 있다. 이에 본 연구는 LG경제연구원에서 제시한 지식자산 축적모형(XYZ모형)을 통하여 건설기업의 무형자산(지적자산)의 크기를 객관적으로 정량화 시키었다. 이를 통하여 현 건설기업의 내재가치 수준을 추정할 수 있다.

  • This paper introduces a methodology for construction of ontology-based product knowledge Map. For CPC(Collaborative Product Commerce) environment, engineering application of ontology has been studied . However, there are no generic and comprehensive methodologies for ontology construction yet because of such problems: dependency on experience of ontologist and domain experts and insufficiency of detail stages or rules. To solve those problems, we propose a methodology to construct ontology from engineering documents in semi-automatic. We use middle-out strategy and term's axioms, sub-definitions, to build ontology map. 5-turple ontology structure, semantic network and First order logic (FOL) are used for ontology definition in this study.

  • This research analyzed procedural problems presented in academic writing faced by international students. The result of this research will serve as a basis for suggesting methods of developing a curriculum in Korean writing as a liberal arts education designed for international students. To analyze problems presented in academic writing by international students, the standard of assessment was divided into interaction, knowledge construction, and material quotation. Then, knowledge construction was divided into contents, structure, and expression, and the items were subdivided in each category. These categories of assessment correspond to the genre of academic writing and are different from the existing standard of assessment for academic writing. Applying these standards, this research analyzed 43 texts of academic writing in process for a final paper by international students in an class and presented problems in them. Furthermore, this paper aims to give detailed feedback that can help solve those problems.

  • As domestic construction investment has been gradually reduced, expanding overseas construction is one of the most important issues for Korean construction companies. Among these issues, strategies for overseas CM services have widely been discussed, because the CM services have features of high growth potential and value-added area when compared with other construction sectors. Therefore, recent efforts focus on further development in advanced CM capabilities and expansion to overseas market. However, there has been lack of quantitative research to investigate current status and future direction of CM industry. In this sense, this research investigated what CM has achieved for the past 17years (between 1997 and 2013) and what CM should accomplish for future strategies. The purpose of this research is to statistically analyze total of 2,983 CM service contracts over the past 17 years published in KISCON (Knowledge Information System of Construction Industry) in order to examine current status of CM industry in terms of market type, contract size, commodity type, and owner's type. Based on this research, it is expected to suggest for future strategies and development directions from the CM industry perspective that could provide quantitative analyses, improve current CM statistics systems and strengthen the competitiveness in international CM market.

  • 정보화기술(information technology)의 발전으로 건설현장에서 디지털 카메라(digital camera)를 이용하여 현장상황 및 각종 공사에 대한 이미지 정보를 수집하고 있으며, 많은 관공서나 발주자들 역시 디지털이미지(digital image) 형태의 현장정보관리 및 제출을 수용하고 있다. 본 연구에서는 현장에서 수집되는 디지털 이미지(digital image)를 효과적으로 관리하며, 프로젝트 참여자사이에 효과적으로·공유할 수 있는 인터넷 기반의 현장사진관리 시스템을 개발하였다. 이 시스템은 현장이미지정보를 공종, 위치, 날짜, 업체, 용도 등의 다양한 속성을 이용하여 저장/검색/공유할 수 있는 시스템이며 건설현장에 적용하여 수정보완 하였다. 본 연구에서 개발된 시스템은 현장이미지의 효과적인 관리와 공유뿐만 아니라 정보축적과 재활용을 통한 기업의 지식기반 구축에 활용될 수 있을 것으로 기대된다.

  • Delay, cost overrun and inferior quality in public works are common in Nepal and Cambodia. Almost 90 percent of the civil construction engineers working in the industry were one-degree graduates without appropriate training. The civil engineering education had provided elemental engineering knowledge to the graduates however integrated engineering and management knowledge and skill are essential for efficient infrastructure development. ODA in developing countries had been concentrated in hard infrastructure development without improving the quality of higher education. Integrating ODA to engineering education system would help develop qualified technical manpower and appropriate technology domestically, and improve the efficiency in infrastructure development in developing countries.

  • Generating a project network of a specific construction project is very time consuming and difficult task in the field. To effectiviely automate and support the planning process, we design a case-based project planning expert system inspired by the fact a human expert project planner uses previous cases for planning a new project. A construction project case consist of its specific characteristics and the corresponding project network (i.e. project plan). Using frame based representation. we represent the project features affecting the progress network and the entities composing the project plan such as the buildings, construction methods, WBS (work breakdown structure), activities, and resources. The project planning process runs through most similar case retrieval, case adaptation, and user requirement satisfaction. We represent the construction domain knowledge for each procedure using constraints and rules. We develop the methodology for constraint-based case adaption. Case adaptation process mainly consist of activity generation/deletion and predecence constraint satisfaction, for which we develop the dynamic constraint generation method and connect user-level requirement representation the system-level network modification knowledge. The methodology is being applied to the prototype for apartment construction project planning.

  • Aiming at reducing deaths and injuries involving construction crane operations, OSHA has recently updated its 40-year-old crane safety standards with new rules addressing the use of cranes and derricks in construction. The goal of this change in rule is to deal with the leading causes of fatalities related to crane and derrick operations. Employers in the construction industry are mandated to ensure that employees in the work zone are trained to recognize hazards associated with the use of the equipment and any related duties that they are assigned to perform. However, those responsible at construction sites for the supervision and management of safe crane operations often lack the integrated knowledge of the standards, regulations and best practices for conducting or supervising daily, monthly, or quarterly inspection of cranes. As such, proper planning, management and implementation of crane operations, including inspections are just as paramount to reducing accidents on the construction site. It is important that engineers responsible for the management and planning of crane operations understand the latest OSHA crane and hoisting standards to ensure a safer work environment is maintained. Many on site engineers overseeing crane operations do not have adequate training, experience, and knowledge of the inspection requirements to assess safe crane operation and too often rely on the crane operator's judgement. This paper highlights recent research effort in defining significant changes in new crane and hoisting standards and provides basis for safety construction operations.
