The supply for the apartment complex in Korea has been accomplished by the sale before building system as a way of institutional means to support massive housing supply in the past. Although this sale before building system has helped the provision of the housing, the necessity of that has been weakened in the current housing market. As this market is changed to emphasize on consumer, the necessity of conversion to sale after building system was raised and finally enforced partially. However, the sale after building system has difficulty in ensuring construction fund and the safety of housing business. So, the diversification in the style of business structure we and the strategy for the activation of construction fund will solve these problems. Consequently, this essay examine the change and influence in the construction fund after adopting sale after building system and suggest the appropriate strategy in project financing for providing fund and reducing the risk in construction business.

Interests in knowledge asset as a way of improving the values of companies and as a survival strategy have increased worldwide. In Korea, since the mid 1990s, many construction companies have realized the importance of knowledge and large companies have been forerunners in adopting KM. However, unlike large companies that readily adopt knowledge management, small & medium-sized general and special construction companies lack understanding of knowledge management and have hard time keeping updated with the current information and the state-of-art information technologies due to financial and organizational reasons. This research presents knowledge management strategies, which involves knowledge management adoption plans appropriate for small & medium-sized general and special construction companies as a way of increasing the value and competitive power of the companies.

Carbon emissions in construction stage is very high because lots of construction machines and materials are required to be used at a road construction stage. Many researcher carried out application of carbon emissions estimation methodology during the life cycle of road infrastructure in order to reduce greenhouse gas emissions in the road sector. But the calculation of carbon emissions is difficult because data collection is difficult and calculation procedure is complex. In this study, a basic unit of carbon emissions in construction stage of the road infrastructure was developed in order to get the quantitative determination of carbon that occurs. Carbon emissions of the expressway and common state road was calculated by using the basic unit of carbon emissions and application plan of basic unit of carbon emissions are presented.

For the past several decades, the residential housing market has been led by construction firms rather than consumers; in essence, it has been a suppliers' market. However, the market is experiencing a transition to a buyers' market, the implication of which is that there will be increased competition among the residential building suppliers. For this reason, it is necessary for construction firms to prepare new strategies to respond to the rapidly changing market environment. Furthermore, consumer satisfaction should be valued more highly than in the past, and should be a baseline in formulating construction product development strategy. For the pre-classified 13 apartment building segments, questionnaire surveys are conducted for the 50 CS (Customer Satisfaction) experts to evaluate their perceptions on the weighing of the quality of each apartment segment. Data obtained from a survey of experts was analyzed from an industry perspective utilizing the AHP technique. Analysis results indicate that the CS experts valued the kitchen & dining area more highly than all other segments. Specific analysis results and implications drawn from the study can be a valuable basis for marketing, product development, and quality management.

The first full-scale u-City operation has started in Dongtan u-City. As local cities take over and operate the u-City, unexpected issues arise such as securing the budget of operating costs and self-providing the costs with business models utilizing the u-City assets. The paper presents a strategy for solving these issues. The strategy provides a foundation(infrastructure) for long-term operation models which may reduce the long-term operating costs. In order to establish the economic operating framework of u-City, suggested are some cost-reduction models based on the operating costs structure. For each model, a base framework with comparative analysis of operating costs is provided. With these models, each u-City may select a relevant model according to the characteristics of it. We hope that the framework provides the foundation for efficient and sustainable u-City operations.

This study proposes a system identification technique for a fiber-reinforced polymer deck with neural networks. Neural networks are trained for system identification and the identified structure gives training data in return. This process is repeated until the identified parameters converge. Hence, the proposed algorithm is called an iterative neural network scheme. The proposed algorithm also relies on recent developments in the experimental design of the response surface method. The proposed strategy is verified with known systems and applied to a fiber-reinforced polymer bridge deck with experimental data.
