This research estimates the necessity of a better governance plan on the purpose of fulfillment energy recovery by building resource recycling system for biomass resources and waste resources that derive from agricultural and mountain village areas. The utilization of new renewable energy technology which uses waste and biomass sources diverse as variety of resources, collecting method, operator etc. and is structurally complicated the formation of policy is also very difficult. There is failure because of the problems which occurs from the policy led by government. Biomass Town Development Project should be made through the central government and the local government integrated support system and should be formed a consultative group in order to process the project mutually with these two department including the experts from the related areas. This consultative group, while government organizations carry out the hub function of strategic knowledge management, should carry out the control tower function to be able to be net working transfer the information with the cooperation of private and government so vitalize the communication area among the related actors. And to be able to increase the participation rate of the local people the consistent and various educations should be given so a smooth business promotion progress will be desired through the change of perception and coactive participation of people.

Water is a strategic resource for Singapore due to its small land mass and more than half of the mainland serves as catchment for raw water, including construction sites. Construction site typically involves earthworks and in conjunction with the frequent and intense rainstorm in Singapore, produce runoff of high turbidity due to suspended sediments. The resulting high concentration of suspended sediment in construction site runoff very often leads to aesthetically unpleasant reservoirs and potentially increases the treatment cost of raw water. To mitigate this, the local standard requires the discharged concentration of total suspended solids of construction runoff leaving a construction site to be less than 50mg/l which is a very high standard. This paper will present, examine and discuss particular issues and practices of Singapore's construction industry in meeting this requirement. The focus will be on two areas: Government lead initiatives and industry practices. How the government agencies worked together with the industry professionals to develop a system to ensure meeting of the standard is discussed. In addition, the types of industry practices, including various Best Management Practice to reduce erosion in construction sites and implement effective sedimentation on construction sites are examined.

In this paper we propose a framework for an Object Relational IFC Server (OR-IFC Server). Enormous amounts of information are generated in each project. Today, many BIM systems are developed by various CAD software vendors. Industry Foundation Classes (IFC) developed by International Alliance for Interoperability (IAI) is an open standard data model for exchanging data between the various BIM tools. The IFC provides a foundation for exchanging and sharing of information directly between software applications and define a shared building project model. The IFC model server is a database management system that can keep track of transactions, modifications, and deletions. It plays a role as an information hub for storing and sharing information between various parties involved in construction projects. Users can communicate with each other via the internet and utilize functions implemented in the model server such as partial data import/export, file merge, version control, etc. IFC model servers using relational database systems have been developed. However, they suffered from slow performance and long transaction time due to a complex mapping process between the IFC structure and a relational-database structure because the IFC model schema is defined in the EXPRESS language which is object-favored language. In order to simplify the mapping process, we developed a set of rules to map the IFC model to an object-relational database (ORDB). Once the database has been configured, only those pieces of information that are required for a specific information-exchange scenario are extracted using the pre-defined information delivery manual (IDM). Therefore, file sizes will be reduced when exchanging data, meaning that files can now be effectively exchanged and shared. In this study, the framework of the IFC server using ORDB and IDM and the method to develop it will be examined.

This research shows the improved methodology which can be applied for universities which want to set up their GHG inventories. In other words, we tried to make guideline in problems due to the unique characteristics of universities. This guideline will help university to deal with the problems they are facing: For example university has less enforcement in operational control compared to the business sector. And it also has various usage of facilities, although these facilities are not maintained by same principal agent. The difference between owner and manager is an another reason for difficulty in setting group organization. The improved and adaptable methods responding to these problems were suggested from this research. The results of this research says the new definition of function for various actors in university for quality control and quality assurance. Because the suggestions made in this research which concerns with criteria for building of universities' GHG inventories were all read by current legislation, there is an anticipation that this can be an official guideline that can be applied to the universities right away.

As the prefabricated shoring system structure, which is a temporary structure, is often collapsed due to various reasons during concrete pouring, and directly affects not only the safety of the workers but also the quality of the final building, it is necessary to ensure the safety. It is considered that the pipe supports which are widely used as the prefabricated shoring materials in the construction site do not satisfy the performance criteria in many cases. Therefore, this study investigated the detailed conditions for satisfying the performance criteria and suggested the factors for improving the quality control level in order to prevent collapse accidents due to pipe supports reused at the construction site, As the results of test in order to understand the effect of the pipe supports (V2), which are being reused in the field, on the performance by factor, the performance was evaluated to be high in case of the small female screw clearance and the supporting pin with 12mm in diameter or larger.
