This paper presents a fundamental study to establish a standardization system of the Construction Continuous Acquisition and Life-cycle Support(CALS). A state of the art in standardization of the Construction CALS is reviewed to find some defects in developing CALS system in construction industry. It is analyzed that three major parts were needed to set up a standardization system for the Construction CALS. Firstly, the range of Construction CALS standardization is set up to identifying Construction CALS and defining the standards and standardization. Secondly, the strategy to carry out more effectively in Construction CALS standardization and make the relationship of the concerned system presented here can be used to establish the Construction CALS standardization system. In addition, the spread and application device are proposed to use Construction CALS standards at public institution and construction related companies. Conclusively, a classification of the Construction CALS standards was proposed and some objects to be standardized were represented in that. Results studied in this paper will provide the primary information and basic model to develop a guideline for standardization of the Construction CALS.

In the Korean domestic construction field, there are a lot of problems related to construction information exchange and sharing owing to the absence of construction drawing information exchange standard. To remedy the aforementioned inefficiency effectively, it is necessary to apply the STEP standard which is known as an international standard for achieving the establishment of Construction CALS. This study focus on suggesting a methodology to activate the STEP based construction drawing information exchange standard to the current construction drawing information exchanging and sharing practice. In this paper, the domestic and foreign standardization projects related to the construction drawing information have been investigated and analyzed. In addition, a methodology of applying and activating the STEP standard has been suggested. Finally, a verification and certification methodology for applying the CALS/EC construction drawing information exchange standard(STEP) have been suggested.

For running various construction processing information and technological information, it is supplied by Construction CALS/EC systems properly during whole facilities life cycle. So it is urgently necessary to change Regional Construction 8t Management Office (RCMO) equipment construction administration business to electron processing system (CALS/EC). From construction work plan to completion, a present storage documents system is unsystematic. Therefore, it needs management system to store documents and to read in turn documents properly. This research suggest that it is to connect with various information systems and Construction CALS/EC for RCMO which is running public construction field. So it can be driven systematic and effective administration system about public construction business by Web-based present construction situation information system.

This study aims to explore the ways of reinforcing the competitive edge and substance of company through e-business in furniture industry by presenting the e-business model of furniture industry which faces the opportunity of challenge in the course of industrial restructuring. e-business model can take various types depending on the environment, feature and competitive edge that each company faces. For example, it is general in the fields of manufacturing company to study the model by dividing into Sell Side for sales to the customers, and Buy Side for purchase of raw materials, Integrating both sides. In furniture industry, Sell Side has the feature of giving a priority in the quality and price rather than brand image in the purchase type of consumer. Especially, it shall not be overlooked that majority of furniture is delivered to the consumer indirectly through the construction company. As such, e-business should be promoted in a way to expand the point of contact for consumers, rather than to construct its own point of contact for consumers. The percentage of importation of raw lumber is high and the standardization was insufficient in Buy Side.

Clean development mechanism (CDM) validity study was conducted to suggest better and more adaptable CDM scenario on water treatment plant (WTP). Potential four scenarios for CDM project; improvement of intake pumping efficiency, hydro power plant construction, solar panel construction and system optimization of mechanical mixing process were evaluated on S-WTP in Korea. Net present value (NPV) of each scenario was estimated based on sensitivity analysis with the variable factors to investigate the CDM validity percentile. Hydro power plant construction was the best option for CDM business with 97.76% validity and $1,127,069 mean profit by 9,813 $tonsCO_2e$/yr reduction. CDM validity on improvement of intake pumping efficiency was 90.2% with $124,305 mean profit by huge amount of $CO_2$ mitigation (10,347 $tonsCO_2e$/yr). System optimization of mechanical mixing process reduced 15% of energy consumption (3,184 $tonsCO_2e$/yr) and its CDM validity and mean profit was 77.25% and $23,942, respectively. Solar panel construction could make the effect of 14,094 $tonsCO_2$ mitigation annually and its CDM validity and mean profit was 64.68% and $228,487, respectively.

To succeed in ERP construction, the purpose of ERP setup must be completed. To accomplish this end, it is required to analysis business process completely and make a plan in detail. For ERP providers', they must support a characterized ERP construction methodology and lower the construction cost by improving an ERP package by making it easy to customize. But, because imported EHP products that are supplied currently are designed for the standard and the rationality, they have a limit to support custom processes of domestic companies. On the contrary, ERP products by domestic companies are unable to support a consistent methodology of constructing ERP system. This is a main reason why much time and costs are consumed than that of an original plan. For solving the problems, ERP packages should provide a consistent process modeling methodology and a modeling tool which can support this methodology. Furthermore, customizing cost must be lowered by implementing reusable components from the process models. This Paper describes a component-based ERP Package system which has peculiar modeling tools and development tools. We describe the modeling methodology and the business component definition of the ERP system. Finally, we describe its customizing process based on these process designs and business components.

MOCT(Ministry of Construction St Transportation) suggested "A Plan for Implementation of Knowledge-based Economy for the Construction Industry" to add high value to a construction industry. by means of knowledge-based management. However, there is no knowledge management system which considers characteristics of a domestic construction industry. So a useful knowledge vanished the moment a company terminated a construction Uoject. Therefore, it is necessary to develop "An application method of a knowledge management system for the construction industry" which takes a real environment into consideration. This study aims to present the road map of a knowledge management system which helps the bodies of the construction industry(government, research center/university, enterprise, etc) to do a knowledge activity efficiently. To accomplish this objective, we analyzed overall knowledge management activities. In addition we suggested an implementation direction and strategy of a knowledge management system for the construction industry. As results of this study, we presented the road map of a knowledge management system for the construction industry, which is composed of policy forum, study forum, professional forum, research forum and knowledge 8t information DB. We expect that results of this study will be used as a basis for implementing the knowledge portal that brings a construction industry to a high value added industry.
