최근 국내에서 많이 시행되고 있는 BTL(Build Transfer Lease)사업은 수익성이 낮은 문화, 교육, 복지부문의 사회기반시설을 조기에 확충함으로써 국민들의 삶의 질을 높여주는 역할을 한다. 그러나 현재까지 BTL사업의 공사비는 초기공사비에 중점을 두고 있으며, 상대적으로 운영비 산정에 대한 합리적 기준이 정해져 있지 않아 비효율적인 낮은 운영비 관리체계가 되고 있다. 저가 운영비는 사업완공 후 시설 운영시 서비스의 질을 저하할 수 있고, 사업의 성과에도 큰 영향을 미친다. 따라서 본 연구에서는 기존 하수처리시설의 운영부문에 대한 실적자료를 이용하여 사업계획 초기에 운영비와 운영인력을 산정하는 방안을 제시한다. 이러한 연구는 향후 BTL사업으로 시행되는 하수처리시설의 계획시 시설 규모에 따른 개략적인 운영비 산정에 활용성을 갖을 것으로 기대되며, 타 시설물의 BTL사업 운영비 산정체계 구축시 참고 자료가 될 수 있다.

본 연구는 R&D 프로젝트 관리자의 리더십이 제품개발성과에 미치는 영향력을 밝히는데 목적을 갖고 프로젝트관리 R&D업무와 관련된 전문가집단(제조, 건설 엔지니어링, 조선, 플랜트, 정보통신)분야 175명을 대상으로 실증 조사하였다. 조사결과를 보면 R&D 프로젝트 관리자의 리더십이 제품 개발 성과에 미치는 영향은 유의하지 않은 것으로 나타났으며 프로젝트 스폰서 역할의 매개효과는 유의적인 것으로 나타났다. 이는 다양한 전문분야별 전문가의 참여로 구성되는 프로젝트에 있어 집단 간 복잡한 관계와 역할에 따른 효율적인 통제와 관리가 요구되는 리더의 리더십이 중요함을 나타낸 것을 의미한다. 리더의 효율적인 리더십에 의해 조직 내 구성원들의 협력과 제한된 시간 내 핵심역량의 결집을 통해 성과를 높일 수 있음을 시사한 것으로 평가할 수 있다. 종합하면 본 연구의 핵심 결과는 프로젝트 관리자의 리더십 극대화를 위해 프로젝트 스폰서의 역할증진을 위해 프로젝트 리더와 관련된 매개적 역할을 적극적으로 수행해야 함을 의미하고 프로젝트 스폰서의 매개역할은 프로젝트 관리자의 리더십에 영향을 줌으로 프로젝트 관리자의 리더십에 영향을 미쳐 최종적으로 프로젝트 성과 품질에 영향을 끼치는 것으로 요약할 수 있다.

We studied the use of time-related information, with and without prediction, to support human operators performing moni-toring and control tasks in the process. Based on monitoring and control techniques used for Project Management we developed a display design for the process industries. A simulated power plant was used to test the hypothesis that availability of predictions along with information on past trends can improve the performances of the human operator handling faults. Several designs of dis-plays were tested in the experiment in which human operators had to detect and handle two types of faults(local and systems wide) in the simulated electricity generation process. Analysis of the results revealed that temporal data, with and without prediction, signifi-cantly reduced response time. Our results encourage the integration of temporal information and prediction in displays used for the control processes to enhance the capabilities of the human operators. Based on the analysis we proposed some guidelines for the de-signer of the human interface of a process control system.

우리나라 최초의 원자력발전소인 고리 원전 1호기의 폐쇄가 결정됨에 따라 원전 해체가 화두가 되고 있다. 원전 해체는 우리나라에서 한번도 경험해 보지 못한 일로 해체 과정도 어렵고 시간도 많이 소요된다. 그 일부분인 해체물량 또한 파악이 어렵다. 본 연구에서는 최근 건설산업에 많이 활용되고 있는 BIM 기술을 원전 해체 물량산출에 활용할 수 있는 방안을 제시하였다. 그 결과, 원전 해체 공법선정 및 공정 확립, BIM 모델링 환경 준비, 작업분류체계 구축, 객체분류체계 구축, BIM 통합모델 작성, BIM 객체에 물량 속성 배분 등의 방안을 제시하였다. 제시한 방안은 영구정지 대상 원전이 집중적으로 발생하는 시기부터 유용하게 활용될 수 있다. 이에 기반한 기술확보를 통해 나아가 해외 원전 해체 사업 수주에도 유리하게 작용할 것으로 기대된다.

Korea Water Resources Corporation (KOWACO) operates nine hydroelectric power stations on the Han River, Nakdong River, Geum River & Seomjin River Areas. KOWACO will take the lead in improving the efficiency of water resources supply in this parer, KOWACO Generation Intergrated Operating System(GIOS) project will improve the generating plant, hydraulic structures, switchgear, and station controls, alarms and services for unmanned remote controlled operation by modern intergraed SCADA system. Mordern SCADA is used to cover all computer systems designed to perform the following main functions: - to collect data from industrial plant devices. - to process and perform calculations on the collected. - to present collected and derived data on displays on. - to accept commands entered by human operators and act on them such as sending control commands to plant devices.

In steel making plant, sampling system for raw material such as iron ore, limestone is necessary for quality control purpose. For the sake of efficiency and productivity, automation of the sampling system is highly desirable. From technical standpoint, the development of the automated system requires multi-disciplinary domain knowledge such as mechanical engineering, industrial engineering, information technology and computer engineering. Up to present time, the development has been mainly carried out by a single domain expert with project manager. The automated system developed in this way caused problems in the final system. This paper suggests a systems engineering approach to the development of automation for raw material sampling plant via a tailored process called Plant Systems Engineering (PSE) Process based on ISO/IEC 15288. Through the PSE process, we could derive right requirements and architecture of the Systems Of Interest (SOI), and we were convinced that the PSE Process can be applied to many other Plant Systems.

This article describes a systematic roadmap master plan for advanced industrial safety and health policy in Korea, with an emphasis on. Since Korean industries had first emergence of industrial safety and health policy in 1953, enormous efforts have been made on upgrading the relevant laws in order to reflect real situation of industrial work environment in accordance with rapid changes of Korean and global business over three decades. Nevertheless, current policy has major defects; too much techniques-based articles, diverged contents in less organization, combined enforcement and punishments and finally enforcing regulations full of commands and control. These deficiencies have make it difficult to accommodate changes of social, industrial and employment environment in customized fashion. The approach to the solution must be generic at the level of paradigm-shift rather than local modifications and enhancement. The basic idea is to establish a new system integrated with a risk assessment scheme, which encourages employers to apply to their work environment under comprehensive responsibility. The risk assessment scheme is designed to enable to inspect employers' compliances afterwards. A project comprises four yearly phases based on applying zones; initially designating and operating a specified risk zone, gradually expanding the special zones during a period of 3 years (2010-2012) and the final zone expanded to entire nation. In each phase, the intermediate version of the system is updated through a process of precise and unbiased validation in terms of its operability, feasibility and sustainability with building relevant infrastructures as needed.
