국내외 건설분야에서는 건설CALS 구축 등의 건설정보화를 위해 다양한 노력을 기울여 오고 있다. 이러한 건설정보화는 전산시스템 구축 자체에 많은 비중을 두고 있는 반면, 건설업무의 업무프로세스 재설계 등의 분야는 다소 미흡한 실정이다. 이를 위해서는 건설업무 절차구성을 위한 체계화된 프로세스 개념을 도입한 전산화 방법론 및 특화된 프로세스 모형화기법이 요구되고 있다. 본 연구에서는 이러한 BPR의 건설분야 적용성 확보 및 정보화기술과의 연계성을 고려하여 체계적인 건설업무 프로세스의 구축을 위한 건설업무 BPR 방법론과 업무프로세스 모형화기법을 제시한다. 또한 제시된 모형화기법은 웹기반의 프로세스 모형화시스템으로 개발하여 실제 프로젝트의 적용을 통해 활용성을 검증한다. The construction industry concentrates their efforts on construction information technology (IT) including construction CALS. However, the actual circumstances for construction IT focuses on building hardware and it neglects importance of business process reengineering (BPR) for construction tasks. A systematic process modeling method and a computerized model by process concept need for building construction BPR. This study develops a generalized BPR procedure for construction projects, and then suggests a new process modeling method for construction BPR that consists of object-related process model (ORPM). Finally, this study develops a web-based ORPM Builder (ORPMB) based on the ORPM methodology, and the applicability of the developed system is verified by a case study with practical construction processes.

Objective: The aim of this study was to compare the electrodiagnostic outcomes of carpal tunnel release in patients with and without diabetes with carpal tunnel syndrome (CTS), and to evaluate the effect of diabetes mellitus (DM) on electrodiagnostic outcomes. Method: We conducted a retrospective analysis of 67 patients with electro-diagnostic evidence of CTS. Patients were classified into two groups according to the presence of DM. Both groups were evaluated using nerve conduction studies preoperatively and 3 weeks and 3 months postoperatively. Results: There were no statistical differences in any of the electrodiagnostic parameters between groups 3 weeks postoperatively. However, there were statistical differences in the amplitude and the latency of compound muscle action potential, and sensory nerve conduction velocity 3 months postoperatively. Conclusion: Patients with DM did not show a significantly different outcome 3 weeks after surgery but showed a worse electrodiagnostic outcome 3 months after surgery than those without DM.

건설분야 기술문서들은 과거 종이 문서형태에서 전자화 형태로 변화되고 있으며, 휴대용 전자기기로 관련 규정을 검색하여 활용하는 사례도 증대되고 있다. 그러나 이러한 기술문서들의 전자화 형태는 접근성은 개선될 수 있지만 여전히 규정 자체의 전자 문서화에 그치고 있다. 규정에 관련된 기술 내용의 시각적 이해도를 높이기 위한 동영상, 에니메이션(Animation), 가상현실(Virtual Reality, VR)정보 등이 연동되지 않아 실무자들의 기술적 이해도를 높이는 데는 한계가 있다. 이러한 점을 개선할 수 있는 것이 전자매뉴얼이다. 전자매뉴얼은 시방서, 가이드라인 등 문서형태에 멀티미디어 기능이 연계되어 사용자와 대화형태로 운용되면서 실시간으로 정보 습득이 가능하도록 하는 전자 문서체계이다. 본 연구는 건설분야의 기획단계에 운용가능한 전자매뉴얼의 구성 방안과 모형을 구축하고, 적용 시나리오를 구성하여 활용성을 검증한다. 또한 전자매뉴얼의 적용시 파급효과를 AHP기법으로 분석하여 건설분야 전자매뉴얼의 활용성을 제고하는데 목적이 있다. Technical documents in the construction field are changing from paper documents to electronic ones. As a result, the industry witnesses a trend of using portable electronic devices in searching or retrieving necessary information such as relevant regulations. Despite the improvement in the accessibility to general technical documents, a limitation is still found in accessing the electronic documents on the regulations. We see the barrier for field engineers to enhance their technical knowledge. One of major barriers is that videos, animations, and virtual reality information to enhance the visual understanding of technical content related to regulations are not linked. It is the interactive electronic technical manual (IETM) that can address such issues. The IETM is an electronic document system that enables real-time information acquisition while operating in the form of conversations with users by linking multimedia functions to document types such as specifications and guidelines. This study establishes a model of the IETM that can be operated in the planning stage of a construction project. The study also verifies its usability with a hypothetical case study. This study aims to improve the usability of the IETM in the construction project by analyzing the application effect of the IETM using the AHP technique.

Construction cost estimating is a procedure for surveying the price to complete a project. The results from cost estimating are used as scheduled budgets by public organizations and actual costs by contractors. This study analyzes the existing construction cost estimating system by the comparative study of cost items in Korea and Japan, and then suggests some methods with improvement related to the problems awaiting solutions. The proposed methods include the reorganized cost items for estimating construction cost and the improved procedures for estimating construction cost and the improved procedures for estimating construction equipment cost.
건설공사의 일정계획수립을 위한 리스크관리기법에 관한 연구

Project risk management is a management technique of identifying, analyzing and responding potential risk factors in project life cycle. The importance of risk management has been overlooked in the Korean construction industry. The industry's practice of risk management is limited to and concentrated on the construction stage, which cannot properly assess potential risk factors during the project life cycle. Moreover, the research and systematic development efforts on the subject have been very few in the industry. The purpose of this study is to improve current construction scheduling practices by providing an probabilistic scheduling model that can be utilized during construction planning stage.

The computerization is an important factor for scientific construction management. Con-struction management softwares are being widely used for computerizing project control and scheduling. The code systems in those softwares enable various classifications of con-struction information such as filtering, sorting and grouping, and facilitate easy appli-cation of computer system. This study analyzes the code systems of three softwares, which are representatively used in the construction sites, through a comparative analysis for the applicability in construction management. Finally the study suggests a desirable structure of code system and a selection criterion of software to improve the applicability of construction management softwares in the construction sites.
