  • Carbon emission calculation guidelines provided by the Korean Ministry of Land, Infrastructure and Transportation (MOLIT) and existing environmental load assessment studies have suggested a method for estimating based on the volume determined after the design development. Therefore they are not being helpful in the decision making of the environmental economics of road facilities in the planning stage in which specific information on construction output volume is lacking. Based on literature analysis of existing studies and consultation from a group of construction environmental professionals, 12 types of property information considered to be related to environmental load were selected from an inventory of information that will be available in the road planning stage. In addition, multiple regression analysis was performed based on the environmental load computed through the life cycle assessment (LCA) of 40 national highway project cases of Korea to deduce five impact factors of environmental load in the road facilities planning stage.

  • Substantial research has been performed on the data standards and exchanges in the AEC/FM industry over the past several years. The growing popularity of BIM technology is based heavily upon a perception that the technology can facilitate the sharing and reuse of information during a project life-cycle. Although many researchers and practitioners are in agreement about the potential applicability and benefit of BIM in construction, it is still unclear why BIM is adopted, and what factors enhance implementation of BIM. Thus, BIM acceptance and use remains a central concern of BIM research and practice. Therefore, we propose the key factors affecting the acceptance of BIM in construction organizations using factor analysis. The key factors for BIM acceptance are identified through a literature review in TAM (Davis 1989) and related theories, and consolidated by interviews and pilot studies with professionals in construction industry. Based on the factors, a questionnaire was designed and sent out to construction organizations such as contractors, architects, and engineers in Korea. Total 148 completed questionnaires were retrieved. Using factor analysis, key factors were grouped into six dimensions. These findings will clarify what the highly prioritized factors are, and can also be used in an assessment tool for the performance of BIM utilization.

  • Australia has joined many governments to adopt public-private partnership (PPP) as a major strategy for procuring infrastructure for decades. However, failures have occurred although the market has been considered to be a mature and sophisticated one. Failures have typically been traced back to inappropriate economic evaluation and a lack of value-for-money. In particular, a literature review has identified that there was no holistic consideration on the evaluation of procurement transactions of PPP projects. The transaction costs of PPPs were not handled properly. In this paper, theories of transaction cost economics are proposed for the purpose of such a holistic institutional economic evaluation. These theories are analysed in order to identify potential critical success factors for a strategic infrastructure procurement framework. The potential critical success factors are identified and grouped into a number of categories that match the theories of transaction cost economics. These categories include (1) Asset Specificity, (2) Organizational Capability, (3) Transaction Frequency, (4) Behavioural Uncertainty, and (5) Environmental Uncertainty. These potential critical success factors may be subject to an empirical test in the future. The proposed framework will offer decision makers with an insight into project life cycle economic outcomes needed to successfully deliver PPPs.

  • 지구온난화를 방지하기 위해 대량의 $CO_2$를 감축 시킬 수 있는 해양 CCS(Carbon dioxide Capture and Storage) 실증 및 상용화를 국내에서 준비 중이다. 해양 CCS 사업은 해양내 심부 퇴적층을 대상으로 대규모 $CO_2$를 수송, 주입, 저장하는 기술로써, 누출 등의 사고 발생 시 인명, 환경, 재산 등에 큰 피해를 야기할 잠재적 가능성을 가지고 있다. 따라서 해양 CCS 사업 안전성을 확보하기 위해서는 생애주기에 걸쳐서 유 가스 생산 해양플랜트에 준하는 엄격한 HSE(Health, Safety and Environment) 관리 방안이 요구된다. 하지만 국내에는 CCS 사업에 적용 가능한 HSE 법 또는 규정이 없을 뿐만 아니라 관련 연구도 미비한 상황이다. 이에 본 연구에서는 국외 해양플랜트 관련 HSE 관리 방법론, 해양 CCS HSE 관리 가이드라인 및 국외 사례를 분석하고, 이를 통하여 국내에서 해양 CCS를 추진시 HSE 관리 프레임워크 구축에 필요한 요구사항을 도출하였다. 이를 위해 본 연구에서는 먼저 범용적으로 활용되는 위험 관리방법론인 ISO 31000에 대한 분석을 수행하였다. 또한 해양플랜트 HSE 관리체계를 체계적으로 구축 운영 중인 노르웨이와 영국의 해양 CCS HSE 관리가이드라인 및 적용사례를 각각 분석하였다. 이를토대로 국내에서 해양 CCS 사업 추진시 HSE 관리 프레임워크 구축을 위해 우선적으로 수행해야할 사항으로 HSE Philosophy의 작성의 필요성을 피력하였고 생애주기 단계에 따른 HSE 관리 프로세스를 제안하였다. 본 논문에서 제안한 HSE 관리 프레임워크를 통해 국내 해양 CCS 실증 사업 추진시 기획 설계 단계부터 HSE 관리를 한다면 보다 안전하고 체계적인 사업을 이행할 수 있을 것으로 기대된다.

  • 전세계적으로 2015년 파리기후협약에서 정한 목표에 따라 2050년까지 탄소중립을 위하여 각 국가는 감축목표를 수립 및 선언하고, "장기 저탄소 발전전략" (Long-term low greenhouse gas Emission Development Strategies, LEDS)을 수립, 감축 목표 설정을 위한 로드맵 등을 발표하고 있다. 국제사회의 탄소중립사회 전환 가속화에 따라 2020년말까지 128개국이 탄소중립을 선언하였으며, G20 회원국을 중심으로 지속적으로 탄소중립선언이 확대되고 있다. 우리나라도 2020년 12월 탄소중립의 능동적 대응을 통해 탄소중립과 경제성장, 국민 삶의 질 향상을 동시 달성하는 기반 마련을 위한 "2050 탄소중립 추진전략"을 발표하였고, 이를 위한 정책과제를 단계적으로 추진하고 있다. 우리나라에서 온실가스 감축을 위하여 시행되고 있는 온실가스에너지 목표관리제 및 온실가스 배출권거래제 상쇄제도 등 의무감축제도의 영역에서 벗어나 있어 종합적인 탄소관리는 미흡하며, 현재 광해방지사업으로 인한 이산화탄소배출량을 정량화한 사례는 없다. 따라서, 본 연구에서는 전세계적인 탄소중립의 관심과 정부 정책 기조에 따라 탄소 중립 실현을 위해서 한국광해광업공단의 주 업무인 광해방지사업에 대하여 국내외 탄소배출량 산정 방법으로 제시된 표준방법을 검토하고, 광해방지사업에 적합한 탄소배출량 산정 방법을 제시하고자 하였다.

  • This paper is aimed at proposing the policies for managing archives in the process of promoting Electronic Government System. Although there have been many studies of electronic government project and plans for its establishment, this research examines the electronic government system and its problems on the basis of archival science. What I acquired in this paper is as follows. The development of information technology needs great changes ranging from the nation to the individuals. It becomes common that the use of computerized program for business purposes, computerization of information materials and the effective way of search use of electronic documents. Therefore, more and more countries all over the world have been seeking to promote 'Electronic Government', which applies the fruits of the development in information technology to administration process. Recently, Korea has been rapidly entered into the 'Electronic Government' system being against the traditional way of administration. In electronic government system, the 'Life Cycle' of public records will be computerized. Therefore, it is important to change and develop along with the government's policies for 'electronic government project' in the archival management system. This means that the archival management system which have put emphasis on the textual records should be converted to electronic records system. In other words, the records management in electronic government system requires not the transfer and preservation of the records but the consistent management system including the whole process of creating, appraising, arranging, preserving and using the records. So, the systematic management of electronic records plays an important role in realization of electronic government, but it is a subject to be realized by electronic government at the same time. However, the government have overlooked the importance of archival management for long time, especially the importance of electronic records management system. First of all, this research attempts to infer limits and problems through the theoretical considerations of the existing studies for electronic government and to clear up the relations between electronic government and archival management. Based on this, I'll seek to progress the study through reviewing the present condition of archival management in the process of promoting electronic government and suggesting the policies for enhancing the successful electronic government and the construction of scientific archival management system. Since early 1990, many countries in the world have been making every effort to concrete 'Electronic Government'. Using the examples in other nations, it is not difficult to recognize that the embodiment of electronic government is closely connected with the archival management policies. Korea have completed legal and institutional equipments including the new establishment of "Electronic Government Law" to realize electronic government. Also, Korea has been promoting electronic government with the Ministry of Government Administration and Home Affairs and Government Computer Center as a leaders. Though managing records, especially the management of electronic records is essential in electronic government system, we haven't yet discussed this section in Korea. This is disapproved by the fact the Government Archives and Records Service has played little role in promoting electronic government project. There are two problems relating this environment. First, present system can't meet the consistent 'Life Cycle' ranging from the creation to the preservation of electronic records. Second, the 'Life Cycle' of electronic records is divided into two parts and managed separately by GCC and GARS. The life of records is not end with the process raged from creation to distribution. On the other hand, the records are approved their value only whole procedures. Therefore, GARS should play a deading role in designing and establishing the archival management system. The answer to these problems, is as follows. First, we have to complete the electronic records management system through introducing ERMS not EDMS. This means that we should not change and develop towards ERMS simply with supplementing the current electronic records management system. I confirm that it is important and proper to establish ERMS system from the very beginning of the process of promoting electronic government. Second, I suggest the developmental integration of GARS and GCC. At present, the divided operations of GCC and GARS, the former is in charge of the management center for electronic business and the latter is the hub institution of managing nation's records and archives result in many obstacles in establishing electronic government system and accomplishing the duties of systematic archival management. Therefore, I conclude that the expansive movement towards 'National Archives' through the integration among the related agencies will make a great contribution to the realization of electronic government and the establishment of archival management system. In addition to this, it will be of much help to constitute and operate the 'Task Force' regarding the management of electronic records with the two institution as the central figures.

  • 건설 산업의 전반적인 생산성 향상을 위하여 시설물의 전 생애주기에 걸쳐 정보의 시스템화가 요구되고 있다. 정보를 시스템화하는 방법의 하나로 3차원 정보모델을 기반으로 정보 관리하는 기술인 BIM(Building Information Modeling)이 활발하게 연구되고 있다. 하지만 BIM 연구의 초점은 대형 사업장에 맞추어져 있으며 중소규모 사업장을 위한 BIM 연구는 미비한 실정이다. 중소규모 사업장의 경우 대형 사업장보다 정보 손실이 더욱 심각하지만, 투자 자원의 부족으로 인해 BIM을 도입하기에는 힘든 실정이다. 따라서 이 논문에는 과도한 투자 없이 BIM의 효과를 얻을 수 있는 중소규모 사업장 대상 맞춤형 BIM 시스템 개발을 위한 연구를 수행하였다. 이를 Pseudo BIM(이하, 의사BIM)이라 정의하였다. 그리고 의사 BIM의 개념과 구축방법에 따라 PLIB Part 42, 건설정보분류체계 등을 활용하여 의사 BIM의 엔진 구조를 담당하는 데이터 사전 구축 방법을 제시하고 Pilot test를 실시하여 의사 BIM의 유효성을 검증하였다.

  • Greenhouse gas and energy reduction goal management system is announced to reduce national CO2 emission in 2011. The target business sector of the system has to follow the procedure of the system and get the assessment. The percentage of the national CO2 reduction goad is 30 % compared to the amounts of BAU. In railway business sector, 6 bodies are included in this system so that railway industry cannot stay and sustain its better position any more than other transportation industry. Most of the industry except Railway industry is struggling to develop its product more environmentally friendly and get the 3rd party certification like Eco-labelling and Carbon footprint. To get environmental certification, LCA method has to be applied because life cycle approach is needed to respond current environmental requirement. The purpose of this project is to facilitate railway vehicle manufacturer obtaining the environmental certification termed Korea EPD. By doing so, the environmental performance evaluation tool would be developed and modelled within the LCA framework and therefore applied especially for rail vehicle.
