As the incidence and mortality of serious disasters in the construction industry are the highest, various efforts are being made in Korea to reduce them. Among them, risk assessment is used as data for disaster reduction measures and evaluation of risk factors at the construction stage. However, the existing risk assessment involves the subjectivity of the performer and is vulnerable to the domestic construction site. This study established a DB classification system for risk assessment with the aim of early identification and pre-removal of risks by quantitatively deriving risk factors using BIM in the risk assessment field and presents a methodology for risk assessment using BIM. Through this, prior removal of risks increases the safety of construction workers and reduces additional costs in the field of safety management. In addition, since it can be applied to new construction methods, it improves the understanding of project participants and becomes a tool for communication. This study proposes a framework for deriving quantitative risks based on BIM, and will be used as a base technology in the field of risk assessment using BIM in the future.

In the digital information environment records have an even closer relationship with business processes and become a core element of organizations' managerial activities. In practice, management is represented as congregation of business outcomes. The importance of records management is increasingly emphasized in terms of organizations' compliance, knowledge-management and risk management. However, there is currently no academic discussion on a between records management and managerial activities. In this context, the study has the notion that this should be defined and acknowledged for public institutions' effective records management. Based on the Malcolm Baldrige Model and ISO 15489, the study discusses a close between records management and management quality. The records management elements of the Malcolm Baldrige model and the managerial quality elements of ISO 15489 were analyzed. Based on the analysis, both common and neglected elements were explored in terms of records management.

ESG (environmental, social, governance) management is being introduced with the goal of sustainable development of the company in risk management, which identifies and judgement various risks that may occur in the industry. In the future, ESG evaluation will be used more as a value judgment tools for corporate sustainability. This ESG evaluation was used to manage the company's accident prevention level. Through morphological analysis of the current ESG evaluation system, it was found that the quantitative 'safety evaluation index' available in ESG was insufficient through analysis of safety evaluation items. In this study, domestic and foreign industrial accident data was analyzed, 'accident contributing factors' that required intensive management were derived, and major safety management items that needed supplementation were selected based on the results. ESG safety evaluation indicators were developed through the process of optimizing the selected items into evaluation factors suitable for 'accident prevention management'.

Due to the downturn in the local construction business, entry into the overseas markets has been regarded as one of the core tasks of the building sector and the government. Thus, entry into overseas markets, not only by large and middle-standing enterprises, but also by small and medium sized enterprises, has recently become a major construction policy. Therefore, this study identified and evaluated overseas construction support policies in the field of construction engineering, ranked them as the policies for developing market development funds, fostering and educating expert workers, and supporting the provision of information on winning orders. Through these policy assessment results, the study proposed improvement measures from the government and from the business side. As for the government viewpoint, a measure of providing information suited to engineers in design companies, project manager (PM), construction manager (CM), a measure of producing skillful workers through the expansion of education support policies, and the promotion of specialized overseas workforce in the construction engineering sector were proposed. In the construction engineering industry, this study suggested measures for securing global expert manpower, sharing performance of overseas construction market development project, strengthening construction project management capacity, and strengthening risk management.

The risk of failure in the development of modern weapon systems has been increasing as the demand on the capability and the resulting complexity of the weapons on the war fields are increasing drastically. The analysis of failure has indicated that the main causes can be the following: one is attributed to the unsatisfaction of the system operation concept; and the other is the use of premature technology. As such, DAPA in Korea is urging that the weapons systems development should meet the required operational capability (ROC) as a critical performance requirement. On the other hand, an approach to risk management is to use the technology readiness level (TRL) assessed for each individual technology alone. However, the method of TRL cannot assess the effect of integration between technologies and cannot be performed at system level, which is crucial to systems development. In order to improve the shortfalls, a concept of system readiness level (SRL) has been studied by introducing the technologies integration and also some forms of analysis of advanced degree of difficulty studied separately, but no model considering both of two reported yet. In this paper, under the framework of meeting the ROC, an improved SRL assessment model is presented, which is also considering the advanced degree of difficulty simultaneously. The application of the improved assessment method is discussed in connection with the life cycle of the weapon systems development in conformance with the ROC of DAPA.

최근 기후변화로 인해 전 지구적인 기후 특성이 변화하고 있으며, 기후 특성의 변화는 수문순환에도 큰 영향을 미친다. IPCC (Intergorvernmental Panel on Climate Change) 6차 기후변화 평가 보고서(2022)에 의하면 AR5 (Assessment Report 5)와 비교해 AR6 (Assessment Report 6)에서는 높은 신뢰도로 기후변화 영향의 범위 및 규모는 보다 확대되었으며, 단기적인 리스크로 극한기후 현상의 빈도와 강도 및 기간이 증가할 것으로 예측하였다. 또한, 중장기적인 리스크로 하천 유량의 규모와 관련한 극한 현상의 변화에 따라 수자원 관리 측면에서 어려움을 겪을 것으로 전망하였다. 위와 같은 기후변화에 대응하기 위해 국내에서는 기후변화와 관련된 다양한 연구가 진행되고 있다. 국내 기후변화 관련 연구로는 ArcSWAT 모형을 활용한 RCP4.5, RCP8.5 시나리오 기반 미래 유출량 추정에 관한 연구와, SWAT, IHACRES, GR4J 모형을 이용한 용담댐 유역의 미래기간 유출량 변화 모의, SWAT과 VIC 모형을 활용한 미래 저유량 예측 시 관측 자료와 비교해 모형이 가지는 불확실성 평가 등 기후변화 영향을 평가 및 예측하기 위한 연구는 활발히 진행 중이다. 하지만, 최근 연구의 주요 동향은 유출 모형을 활용한 미래 유출량 모의에 초점이 맞추어져 있으며, 관측 자료를 통한 기후변화 평가 연구는 부족한 실정이다. 따라서 본 연구에서는 한반도 5대 수계(한강, 금강, 낙동강, 영산강, 섬진강) 유량 관측소의 실측 유량을 활용해 과거기간의 기후변화에 따른 유출특성의 변화와, 미래기후변화 시나리오 자료를 활용한 미래기간 유출특성의 변화를 분석하였다. 분석 인자로 연 유출량, 1일 최대 유출량, 상위 90%에 해당하는 유출량, 하위 10%에 해당하는 유출량 등을 연도별로 분석하였다. 분석 결과 연도별 총 유출량의 큰 변화는 없지만, 홍수 기간의 첨두유량이 증가하는 동시에 갈수 기간 또한 빈도와 규모가 증가하는 양극화 현상이 진행되고 있음을 확인하였다.

Since previous default forecasting models for the firms evaluate the probability of default based upon the accounting data from book values, they cannot reflect the changes in markets sensitively and they seem to lack theoretical background. The market-information based models, however, not only make use of market data for the default prediction, but also have strong theoretical background like Black-Scholes (1973) option theory. So, many firms recently use such market based model as KMV to forecast their default probabilities and to manage their credit risks. Korean firms also widely use the KMV model in which default point is defined by liquid debt plus 50% of fixed debt. Since the debt structures between Korean and American firms are significantly different, Korean firms should carefully use KMV model. In this study, we empirically investigate the importance of debt structure. In particular, we find the following facts: First, in Korea, fixed debts are more important than liquid debts in accurate prediction of default. Second, the percentage of fixed debt must be less than 20% when default point is calculated for Korean firms, which is different from the KMV. These facts give Korean firms some valuable implication about default forecasting and management of credit risk.

The government announced a plan for fund support to the enterprises with high possibility of recovery and early restructuring for the enterprises with low recovery by objectifying credit assessment system. Such announcement of government could be extended to restructuring risk of middle standing enterprises with low financial soundness by establishing the basis to prepare prompt restructuring by reinforcing the basis for restructuring through capital market. This research analyzed financial soundness based on the financial evaluation of bank by selecting 10 middle standing construction companies which focused on housing business in 2019, based on such analysis result, it was confirmed that there was a high possibility of restructuring risk. This research determined that there would be a decrease in growth rate of construction industry on the whole in 2020 due to fall of economic growth rate and reinforced real estate regulation, accordingly, there's a big possibility for middle standing construction companies with paid-in capital ratio due to its low possibility of maintenance of stable credit rating. This research established KCSI assessment model by utilizing the material of a reliable research institute in order for middle standing construction companies to evade restructuring risk, and indicated risk ratio differentiated per each item through a working-level expert survey. Such research result could suggest credit risk reduction method to middle standing construction company management staffs, and prepare a basis to evade restructuring risk.
