Because of its unique characteristics, the construction industry tends to be affected by economic environment more than any other industries. The domestic construction industry was forced to change its management pattern and system when it went through the foreign currency crisis, and since then, the construction industry has been growing in terms of quality over last 10 years, breaking from the quantitative performance-oriented growth in the past. The study was intended to integrate the financial data of the companies during the period before and after the foreign currency crisis so as to analyze the effect of environmental changes on management performance of the companies. It was aimed at evaluating the changes to the stability, profitability and the growth potential, and collecting the data on variation of the market scale, price of resources such as material and labor and the financial environment, thereby analyzing the correlation with the management performance. The study, to deal with the difficulties which are anticipated, like the foreign currency crisis experienced in the past, was also intended to identify the correlation between the economic conditions and the performance of the construction companies, using the experimental data in the past.

Generally, building construction projects have a complex decision-making process because of the participation of various agents. In this situation, a final decision is arrived at by relying on subjective judgments based on the experience of project participants. For this reason, a method of assessing the objectivity of opinions is needed. In previous studies, the multi-criteria decision making method was applied to arrive at a final decision objectively, but this method has a limitation, in that the experience of each decision maker is not considered differently in the decision making process. Therefore, this study proposed a theoretical model using the S-shaped growth curve and regression analysis by building construction project type to quantitatively estimate decision-making reliability according to the experience of individual project participant`s. The developed model could be added to the Multi-criteria decision making method, and secure the objectivity and reliability of project participants' final opinion.

Based on assessing the impact of factors on the business efficiency of construction enterprises, the research team proposes policy implications to improve the business performance of listed construction enterprises in Vietnam in the coming time. The study used secondary data collected from the audited financial statements of 25 enterprises listed on Vietnam's stock market in the period 2015-2021 to estimate the factors affecting the business performance of construction enterprises. After collecting, the data will be encrypted and checked. The article uses a quantitative research method by using a linear regression model on Eviews 10 to analyze the data and analyze the impact of factors on the business performance of construction enterprises listed on Vietnam's stock market. The research result shows that firm size and growth rate positively affect business performance while capital structure, receivable management, fixed asset investment, and economic growth have a positive impact on the business performance of construction companies listed on the Vietnamese stock market. Based on this result, the paper also makes recommendations to the Vietnamese construction companies to enhance their business performance.

전세계적으로 녹색 건설에 대한 관심과 필요성이 높아지고 있는 시점에 있다. 정부도 녹색 성장 기조 하에 건축물의 에너지 사용량 저감을 위한 공격적인 목표를 설정하고 다양한 정책적 지원책을 통해 추진하고 있다. 하지만 녹색건설 시장의 지속적인 성장을 위해서는 수요 주체의 녹색 투자 의사 결정을 지원할 수 있는 녹색 건설 투자 비용과 경제적 편익 정보가 제공되어야 하지만, 녹색 건설 선진국에 비해 국내 건설산업계에서는 녹색건설의 비용이나 편익과 관련한 구체적이고 객관적인 자료가 부족하고 분석이 부족한 실정이다. 이에 본 연구에서는 건설 산업 차원에서 녹색 건설 비용의 개념을 정의하고, 녹색 비용 및 편익 정보 체계와 관련한 녹색건설선진국의 다양한 사례를 살펴봄으로써 국내 녹색건축 비용 및 편익 정보 체계의 문제점을 도출하고 개선 방안을 제시하였다. 본 연구에서 제시한 녹색 건설 비용 및 편익 정보의 분류, 축적, 활용 메커니즘이 해당 건설 상품의 경제적 타당성 검증 작업을 견인할 수 있을 것으로 기대한다.

Ordinary heterotrophic organism (OHO) active biomass plays key roles in biological wastewater treatment processes. However, due to the lack of measurement techniques, the OHO active biomass exists hypothetically within the design and simulation of biological wastewater treatment processes. This research was purposed to develop a quick and easy quantifying technique for the OHO active biomass applying a modified batch aerobic growth test. Two nitrification-denitrification activated sludge systems, with 10- and 20-day sludge ages, were operated to provide well-cultured mixed liquor to the batch tests. A steady state design model was firstly applied to quantify the "theoretical" OHO active biomass concentration of the two parent systems. The mixed liquor from the parent systems was then inoculated to a batch growth test and a batch digestion test to estimate the "measured" OHO active biomass concentration in the mixed liquor. The measured OHO active biomass concentrations with the batch growth test and the batch digestion test were compared to the theoretical concentrations of the parent system. The measured concentrations with the batch growth test were generally smaller than the theoretical concentrations. However, the measured concentrations with the batch aerobic digestion tests showed a good correlation to the theoretical concentrations. Thus, a different microbial growth condition (i.e., a higher food/biomass ratio) in the batch growth test, compared to the parent system or the batch digestion test, was found to cause underestimation of the OHO active biomass concentrations.

Transportation infrastructure is critical to economic growth of a country such as China. Careful evaluation of investments in traffic infrastructure projects is therefore pertinent. As traditional evaluation methods do not consider the uncertainty of future cash flows and mobility during project execution, the real option approach is gradually gaining recognition in the context of valuing construction and infrastructure projects. However, many of the cases only evaluate individual options separately although multiple options often exist in a typical large infrastructure project. Using a highway project in China as a case study, this paper first evaluates a deferment option and a growth option embedded in the project. Subsequently, the values are combined using the fuzzy analytical hierarchy process. It is found that the combined value is less than the sum of the two option values. This finding is consistent with the theoretical observations given in past real option literature despite the use of a different approach.
