There is a growing concern in reducing greenhouse gas emissions all over the world. The U.K. has set 34% target reduction of emission before 2020 and 80% before 2050 compared to 1990 recently in Post Copenhagen Report on Climate Change. In practise, Life Cycle Cost (LCC) and Life Cycle Assessment (LCA) tools have been introduced to construction industry in order to achieve this such as. However, there is clear a disconnection between costs and environmental impacts over the life cycle of a built asset when using these two tools. Besides, the changes in Information and Communication Technologies (ICTs) lead to a change in the way information is represented, in particular, information is being fed more easily and distributed more quickly to different stakeholders by the use of tool such as the Building Information Modelling (BIM), with little consideration on incorporating LCC and LCA and their maximised usage within the BIM environment. The aim of this paper is to propose the development of a model-based LCC and LCA tool in order to provide sustainable building design decisions for clients, architects and quantity surveyors, by then an optimal investment decision can be made by studying the trade-off between costs and environmental impacts. An application framework is also proposed finally as the future work that shows how the proposed model can be incorporated into the BIM environment in practise.

Considering our increasingly interconnected organizations heavily relying on business processes and the growing need for timely accurate knowledge to achieve greater agility in the enterprise, the idea of looking at business processes as a knowledge object is gaining momentum. Business process information is knowledge and should consequently be managed as a valuable organizational asset, particularly because organizations need to react in near real time to environmental changes and events. This paper provides an overview of the situation in this field arguing for a better definition of the intersections between knowledge and business process management. When business process is seen as knowledge, it should be managed as such. We assess and discuss some of the resulting benefits and considering the need for greater dynamic integration between the two domains, we look at ontologies as an interesting technical approach to bridging this gap showing an example for an ontology based sales order process.

Distributed planning and decision making can be beneficial from the robustness, adaptability and fault tolerance in multi-robot systems. Distributed mechanisms have not been employed in three dimensional transportation systems namely aerial and underwater environments. This paper presents a distributed cooperation mechanism on multi robot transportation problem in three dimensional environments. The cooperation mechanism is based on artificial capital market, a newly introduced market based negotiation protocol. In the proposed mechanism contributing in transportation task is defined as asset. Each robot is considered as an investor who decides if he is going to invest on some assets. The decision is made based on environmental constraint including fuel limitation and distances those are modeled as capital and cost. Simulations show effectiveness of the algorithm in terms of robustness, speed and adaptability.

This study is to develop and test the types of choice strategy of alliance choice modes of the marketing channel. Previous studies have tended to emphasize such factors as opportunism, asset specificity, frequency as the determinants of the choice strategy. Therefore, this study is to construct a new framework which emphasizes the factors affecting the choice strategy. The purpose of this study is to derive factors affecting in choice of alliance modes. For this study, the data obtained from domestic manufacturing companies was analyzed by use of the discriminant analysis. The results analyzed are that transaction environmental variables affect on the choice strategy to determine the types of strategic alliance modes in marketing channels. And the performance of each mode revealed differently.

Although FRP is relatively new material for constructional use, there are several commercial GFRP bridge decks available today. In this paper we first set variables which decide the design of a GFRP deck based on commercial products. Under the assumption of linear elastic behavior under DB24 load, all the conditions of stability and serviceability are considered. We seek the best solution which minimizes the cross section area using genetic algorithm. The optimal solution shows that the shape is close to the ASSET deck with larger angle of the web and smaller area.

The paper investigates investor sentiment's role in boosting Japanese companies to enhance their environmental, social, and corporate governance (ESG) performance. Using ESG scores of 367 firms between 2005 and 2019 from the ASSET4 database, we find that negative sentiment in the previous year, both firm and market level, can be a stimulation for the company's commitments to its ESG activities next year. Notably, the moderating effect of the business sector and economic cycle on the sentiment-ESG inference are detected in our study differentiating between corporate and market sentiment, which have never been reported before. In detail, we discover that the impact of firm-specific sentiment is less pronounced for high-sensitive ESG firms. On the other hand, the driving force of market sentiment on corporate social behaviors weakens when economic recessions happen. Our results are robust after controlling for potential endogeneity issues and using alternative proxies for market sentiment.

The BIM-based architectural design can be the optimal method to improve all sectors of construction industry and reduce environmental impact through digital technologies. The goals and effects of BIM needs in LH to be newly planned based on the experience of public sectors, which will ultimately contribute to maximization of effectiveness. Referring the excellent case in the UK, the current BIM standards according to maturity level 2 handle the contents related to modeling, collaborative data production, data management and assure BIM data have to be used from building construction to operation and maintenance of buildings. Therefore the strategy for the utilization of BIM for construction projects in LH consisted of three steps; first, the minimization of defects via BIM: second, strengthening the competitiveness of construction and asset management: third, upgrading the system of building production and maintenance control. After this trial, LH can accumulate know-how for building construction to be more costeffective and competitive.

Purpose: This study conducted an empirical study to identify the current status of real estate managers' ESG awareness and to derive recommendations for improvement. Research design, data and methodology: A survey was conducted among those who actually manage real estate assets regardless of region. Descriptive statistical analysis, paired sample t-test, and IPA analysis were conducted using SPSS 27.0 statistical package. Results: The results of the t-test showed that respondents perceived their on-site management achievements to be lower than their perceived importance in all areas of ESG. In the IPA matrix, the mean of achievement is higher than 3, which is moderate. Environment (E) was found to be relatively low in importance. In the Social (S) aspect, the achievement level was low compared to its importance, and Governance (G) was found to be low in importance. Conclusions: Based on the analysis, it seems that policies are needed to emphasize the importance of environmental issues such as greenhouse gas reduction in the environment (E) sector and to strengthen realistic achievement in the social (S) and governance (G) sectors.

Total Economic Value (TEV) provides a framework to estimate the economic value of water resources including groundwater with multiple applications to natural resource economics and environmental economics. Crucial to the application of economic analysis to natural resources are techniques to value the resources as an economic value that is expressed in monetary terms. On the other hand, the aim of TEV estimation is to determine the economic value of water resources including 'use' with production and recreation and 'non-use' such as existence values. TEV is used to assess the economic value of water resources for the multiple goods, and environmental 'services' that are provided by a water resource and also used to assess options for water use, for example balancing production values provided by water resource use against the cost of resource degradation by that use. The value of TEV can be assessed over time where pollution or unsustainable use may reduce the economic value of an environmental asset. Therefore, values are used to assess options of resource use, sometimes leading to policies on resource conservation or allocation. In conclusion, the application of TEV would be well adjusted over Jeju Island where groundwater resources account for more than 98% water resources and the budget of water demand/supply shows disparity over the Island.

In this study, a model was developed to predict for Disinfection By-Products (DBPs) generated in water supply networks and consumer premises, before and after the introduction of advanced water purification facilities. Based on two-way ANOVA, which was carried out to statistically verify the water quality difference in the water supply network according to introduce the advanced water treatment process. The water quality before and after advanced water purification was shown to have a statistically significant difference. A multiple regression model was developed to predict the concentration of DBPs in consumer premises before and after the introduction of advanced water purification facilities. The prediction model developed for the concentration of DBPs accurately simulated the actual measurements, as its coefficients of correlation with the actual measurements were all 0.88 or higher. In addition, the prediction for the period not used in the model development to verify the developed model also showed coefficients of correlation with the actual measurements of 0.96 or higher. As the prediction model developed in this study has an advantage in that the variables that compose the model are relatively simple when compared with those of models developed in previous studies, it is considered highly usable for further study and field application. The methodology proposed in this study and the study findings can be used to meet the level of consumer requirement related to DBPs and to analyze and set the service level when establishing a master plan for development of water supply, and a water supply facility asset management plan.
