Being aware of the risk in advance necessitates intricate processes but is feasible. Although previous studies have demonstrated high accuracy, their performance still leaves room for improvement. A self-organizing feature map (SOM) based neurofuzzy model is developed in this study to provide another alternative for forecasting corporate financial distress. The model is designed to yield high prediction accuracy, as well as reference rules for evaluating corporate financial status. As a database, the study collects all financial reports from listed construction companies during the latest decade, resulting in over 1000 effective samples. The proportion of "failed" and "non-failed" companies is approximately 1:2. Each financial report is comprised of 25 ratios which are set as the input variable s. The proposed model integrates the concepts of pattern classification, fuzzy modeling and SOM-based optimization to predict corporate financial distress. The results exhibit a high accuracy rate at 85.1%. This model outperforms previous tools. A total of 97 rules are extracted from the proposed model which can be also used as reference for construction practitioners. Users may easily identify their corporate financial status by using these rules.

As a knowledge-based economy is emerging, knowledge management (KM) is being rapidly disseminated in both academic circles and the business world. Accordingly, how to effectively manage knowledge is vital to the survival and advance of a company, particularly in project-based industries such as construction. For these reasons, construction companies have adopted IT-based Knowledge management systems (KMS), which is the technology platform and infrastructure that an organization employs to support knowledge management. However, many construction companies have spent resources on developing a KMS that only focus on codification. Furthermore, small and medium-sized companies have limited resources to afford extensive investments. This research addresses the problems found in the current KMS and develops a web-based construction knowledge management portal (CKMP). To achieve these objectives, a case study is conducted and requirements for implementing KM are identified. Based on the identified requirements, this paper builds CKMP using Expert Index (EI), blog, ontology based knowledge retrieval, and wikiblog. The most important functionality of CKMP is their fundamentals to synchronize and support KM process. In order to validate the CKMP, a pilot test with actual users is conducted, and the usability of the system is compared with the current systems. This study is relevant to both the construction industry and academia, as it provides a means of enhancing the performance of KM.

This study aims to investigate the factors that contribute to the sustainable development of 334 Vietnamese construction and real estate companies listed on the Stock Exchange of Vietnam over a 5-year period from 2016 to 2020. By using regression analysis with the support of STATA software through examining the financial statements, which involves looking into crucial ratios including capital structure, profitability, firm size, accounts receivable management, and tangible assets investment, this study sheds light on whether these accounting indicators could help predict the construction and real estate companies growing potential in the future. Nevertheless, these ratios slightly contribute to the explanation of the change in revenue growth ratio, with a result of 1.6%, indicating that the value relevance of accounting information provides a modest and insignificant effect on investment decisions. This is understandable because the Vietnamese construction and real estate market still has many shortcomings in handling unexpected events, as well as the industry's peculiarities related to major capital sources from bank loans. Based on this study, governmental authorities and business executives should plan appropriate risk management policies and measures to contribute to the sustainable development of construction and real estate companies.

우리나라 해외건설 누적 수주 금액은 2012년 6월을 기준으로 5,000억 달러를 달성하였으며 더 나아가 2020년 1조 달러를 목표로 하고 있다. 또한 국내 건설기업들도 해외건설시장 진출을 목적으로 여러 전략을 구상하고 있다. 이러한 목표 달성을 위한 방안으로 본 연구에서는 해외건설 리스크가 적은 ODA 자금을 활용한 해외건설 진출 사업을 제안하였다. 사업 진출을 위한 건설기업의 ODA사업 역량 수준을 분석하기 위해 FGD 기법을 활용하여 34개의 역량 요인을 선정하였고 전문가들을 대상으로 설문조사를 실시하여 BSA 모델을 통해 분석하였다. 사업단계별 중요 관리 요인은 기획 및 발굴(6개), 수주 및 마케팅(6개), 엔지니어링 및 시공(3개) 등 총 15개의 항목이 도출되었다. 이중 가장 기업들에게 필요한 역량강화 항목으로 클레임 및 리스크, 수주활동을 위한 기업의 역량, 그리고 정부의 적극적인 지원으로 나타났다. 각 단계별 중요 관리 요인은 역량별 역할 주체에 따라 개선하여 향후 ODA자금을 활용한 사업 수주 경쟁에 있어서 경쟁우위를 확보할 수 있도록 준비해야 할 것으로 판단된다.

As shown in the accident analysis from 2007, it has been found that causes of accidents on large-scale projects are different from those found in general construction projects. A 300-question survey regarding systematic and practical aspects of safety problems at construction sites was distributed to ten (10) different companies. Participants were to respond subjectively, so that the results could be used to assemble the first formal questionnaire survey. They were collected and compiled by an advisory committee for this study. The resulting surveys were then sent to the division chiefs of the top 100 construction companies in Korea, in order to improve the response rate. The Department of Safety & Health Direction, and the :Ministry of Labor, ROK sent the same sheets to medium and small construction companies that placed within 101-200th of all Korea construction companies. The above safety engineers were classified into four (4) levels, from 1st to 4th, followed by the project dollar amount and risk level. Formulae were developed to assign safety engineers to construction sites by engineer level, the project dollar amount, and the project risk level. Conclusions are summarized as follows: 1) Reviewing the assignment system of experienced safety engineers to large scaled projects - The more experienced the engineers assigned to a project, the higher the level of accident prevention. 2) Enforcing the assignment of advanced level safety engineers to large-scaled sites - At least one advanced-level safety engineer should be assigned to construction sites with projects valued at $15million USD (15,000,000,000). 3) For assigning safety engineers by risk level - Twenty models have been developed to calculate the number of safety engineers to be assigned by risk level. In the future, risk level for each job should be established by the government (as is now the practice in Germany).

This study empirically validates whether the effect of strengthening the legal regulations in the construction industry under the 'Construction Business Act' is true in order to expand the direct construction of the comprehensive construction corporation. Checking the effectiveness of the legal regulation that can force direct construction of the required scope of construction will not only be a logical background in the strengthening of law regulations but also suggest arguments that contradict some construction companies called legal regulation.

The government makes efforts to expand the recycling activities of construction waste soil and to increase the usage of recycled aggregate. Accordingly, it has defined the compulsory usage and quality standard by usage of recycled aggregate. To satisfy these efforts requires both technology to produce recycled aggregate which meets the required quality and companies with the technology. Therefore, it requires to review a current status of facilities at the companies which deal with construction wastes. The companies dealing with construction wastes gradually produce the high quality of recycled aggregate. In particular, companies which has over 3-stage processing system for waste concrete continue to increase and means to remove foreign substances are gradually improved.

The value of intangible assets of a company attracts attention in enterprise management environment drastically changing. Following such a trend, many companies have adopted knowledge management. Especially in construction industry of which success of a project is easily affected by the capacity of various participants and work performers, we may find many cases to which the knowledge managements have been adopted. However, the domestic design companies have tended to be late to introduce the knowledge management or have difficulty in effective use of KMS already constructed. This study suggests KMS based on BPM (Business Process Management) and drives its effects to improve problems mentioned above. We drives the expected effects by studying the existing studies and surveying domestic design companies and suggests Prototype for introducing a real system.
