As the portable information appliance is developed, the demand of flat panel display equipments and parts are steeply increased. Most of all, the applications of LCD such as LCD TV, monitor, digital camera, CNS(car navigation system) and game machine become diversified. With the result that the number of BLU production enterprise is increased and the research on the design of backlight with the superior optical properties is persistently in progress. In this study we developed the pattern design tools for CCFL(cold cathode flourescent lamp) backlight to improve the conventional pattern design environment in which the pattern is designed manually from the experience and the trial and error. For the verification of our research, we designed the light reflection surface patterns for a real model of backlight and we measured the brightness uniformity using the BM-7. From the brightness uniformity measurement, the BLU designed using the presented tool showed the tolerable performance only in the first try of pattern design rather than the fifth try of pattern design in case of the conventional pattern design.

These days construction management is executed in an information technology environment, which creates a large volume of digital data. At the completion of a project, the contractor is required to transfer to the owner the digital data as project deliverables usually in a form of CD's. From an enterprise-wide view point, this traditional way makes the management of project deliverables ineffective as the data accumulated from different projects could be enormous. The objective of this paper is to propose a structured way to utilize a XML database for better management of project deliverables. The XML database provides an environment which users can access through a project deliverable management system (PDMS). A pilot of the PDMS has been developed to test the effectiveness of document control. The result of the test demonstrates that the effectiveness of project deliverable management can be increased by providing a high transportability and usability of data in the construction life cycle.

We are entering into a era of enterprise computing that is characterized by an emphasis on broadband convergence, knowledge s haring, and calm services. Some people refer to this as the "ubiquitous" computing because its focus is on a high degree of connectivity between a company and its customers, suppliers, and channel partners. Ubiquitous computing technology, "RF" stands for "radio frequency"; the "ID" means "identifer". The tag itself of a computer chip and an antenna. The shortest metaphor is that RFID is like a bar-code but is read with an electromagnetic field rather than by a laser beam. Much has already been written about the use of RFID. But there is no has written about the use of RFID in the convention industry. Therefore this study have specific objectives as follows. 1. To give details on the use of RFID in convention. 2. To introduces the key concepts behind RFID technology. 3. To identify advantage & disadvantage of RFID technology using a BEXCO CASE study. 4. To study on ubiquitous convention using RFID and effective operation methods such as entrance identification system, session management, machine management, CRM management, visitor management, and contents management. This results provide into the current status of ubiquitous computing technology in convention industries. Specific advantages by using ubiquitous computing technology(RFID) are one-stop differentiate service, wireless internet service, use of visitor management system, entrance by tag, and U-logistics. On other side, disadvantages are security, stabilization of RFID system, higher price of RFID tag, and commercial scale. Convention by using of RFID technology is currently at an early stage. Convention company as BEXCO need to have the capabilities to adapt, to customize, to commercialize, and to modify technology to suit our circumstances.

Large scale construction disasters such as recent Noryangjin flooding incident and Banghwadaegyo collapse accident are occurring persistently. Thereupon, the role and responsibility of the various construction participants are considered as major element to reduce disaster at the construction site. Construction industry is a process of building construction object by going through planning, designing, constructing, and maintenance controlling in which various bodies of act, from contractor to designer and builders, participate. However, the subject of current safety supervision is focused on the builder, the contract enterprise which directly employs workers, while the safety activity participation of the contractor, who exerts decision-making authority at the highest level, is excluded. Therefore, this study understands the level of awareness and reality on the safety activity of each construction participants from which the improvement plan on the contractor centered safety management system is proposed.
