This paper summarizes the results of a two-year-long research project conducted by the CTBUH on the life cycle assessment (LCA) of tall building structural systems. The research project was made possible thanks to a $300,000 contribution from ArcelorMittal and the support of some of the most important structural engineering firms and players in the tall building industry. The research analyzed all life phases of a tall building's structural system: the extraction and production of its materials, transportation to the site, construction operations, final demolition of the building, and the end-of-life of the materials. The impact of the building structure during the operational phase (i.e., impact on daily energy consumption, maintenance, and suitability to changes) was also investigated, but no significant impacts were identified during this phase.

In the present study, the existing equivalent stain method is improved to make up for its weaknesses. The improved inherent strain model is built considering more sophisticated three dimensional constraints which are embodied by six cubic elements attached on three sides of a core cubic element. From a few case studies, it is found that the inherent strain is mainly affected by the changes in restraints induced by changes of temperature-dependent material properties of the restraining elements. On the other hand, the degree of restraints is identified to be little influential to the inherent strain. Thus, the effect of temperature gradients over plate thickness and plate transverse direction normal to welding is reflected in the calculation of the inherent strain chart. The welding deformation can be calculated by an elastic FE analysis using the inherent strain values taken from the inherent strain chart.

An efficient sensing scheme adoptable in DC-DC converter is described. The output voltage of the whole DC-DC converter is fed back to the input voltage of the sensor. The comparison in the sensor is accomplished by a current push-pull action. With a fixed reference, the comparator can be embodied based on (W/L) ratios. The current-mode scheme benefits the system better than a conventional voltage-mode one in terms of small area, low power consumption.

In this paper, we embodied the environment monitoring system that can acquire correct data in real-time. And we used module that is 2.4GHz IEEE 802.15.4 / Zigbee network for radio communication between nodes. The nodes sense the data of temperature, humidity, illumination periodically. The nodes store the data in their buffer and transmit. We confirmed that the system is in real-time as it is changed instantly due to the varying environment by the simulation Therefore, we can construct the efficient and correct system as applied this system to monitor the environment.

Recently Communication with using IrDA is bing used in various fields. In this paper I designed a receiver by fabricating hardware that used to be fabricated through software, so anyone who don't have knowledge on IrDA can receive Ir Signal easily. This receiver can communicate with CPU through 8 bit data and 3 bit address. Also this receiver can use user-needed CLK because this receiver embodied 16 bit CLK Prescaler.

The purpose of this study is to analyze styles of costume and understand meanings related to costume embodied in the images of Buddha in Baekche period. Visual and textual analysis of the paintings include the images of Buddha in Baekche period was used for the research. The results of this study were summarized as fellows; Budah's hair style is identified as simple, Gae. Buddha wears Sanghati(outer wear) made of Tongeun and Peundanwoogeun, and many cases Sanghati made of Tongeun are usually seen. Three kinds of upper garment were identified; Samkaksika, right and left crossed upper garment, and Peunsam. Samkaksika was frequently seen in the paintings. Lower garment was a Nirasana reach to the ankle, was worn with a belt. Two skirts were also seen occasionally. The symbolic meaning of costume of Buddha was related to its religious meaning and identified as majesty and saintliest, which is harmonized with her simple costume styles. The wrapped style of costume, which did not show the contour of the buddha's body adds mystery. Also, the styles of costume created by different wrapping methods signify originality.

Patchwork is a handicraft to put some certain shapes of small cloths together. Historical records of patchwork was discovered in Ancient Egypt as far back as BC 1000. Patchwork has been popular in the England and in around 13-$14^{th}$ century, European spliced little pieces of cloths for cold necessities, which made the handle of patchwork techniques gradually tend to decorative other than utility. Patchwork designs and techniques were taken across the Atlantic to North America with the early settlers in the mid-eighteenth century. In the early years of $20^{th}$ century, owing to the continuous technological advances, woman got more job opportunities that made patchwork technologies withered. Patchwork art continually evolved on the basis of historical and cultural factors to new styles, the famous Hawaiian, Stained Glass, Mola, Celtic, Victoria, Seminole and many other patchwork styles like that perfect embodied different art and cultures of different nations in different times.

In this paper we implement a robot system consisted of mobile tole robot to be controlled by client through web browser Newly Internet is connected to all network of the whole world. If client uses the network like this, client can control direction of a robot that is selected in free place. In this study, system is embodied in using robot that can move freely in plan place and cod camera that can grab robot image. System transmit image data of cod camera to java server that is placed in web server of internet that is used by client. Java server display incoming data in home page using java applet. Then web browser offer robot image to client and client send remote control signal to robot. Control signal is transmitted to robot by java server and robot receiving signal moves toward direction wanted by client.

Individual authentication system that take advantage of multimodal information is very efficient method that can take advantage of method of speech recognition, face recognition, electron signature etc. and protect important information from much dangers that exits on communication network whole as skill that construct security system. This paper deal product connected with hardware from internet space based on public key sign and electron signature description embodied system. Maintenance of public security is explaining that commercial transaction system implementation that is considered is possible as applying individual authentication.

As Dutch structuralism discovered a possibility that can improve the problem of modem architecture through study on non-western area. Dutch structuralism had tremendous impact on Philosophy, psychology, art history and the style of a dress and many other cultural trend. In architecture, Aldo van Eyck embodied that theory and succeeded to Herman Hertzberger and Piet Blom. As result Structuralism related with architecture has dealt with the participation and domain of residents, namely public domain and private domain, the approach property of public space, middle domain which shows the harmony between public domain and private one, and the structuralism discovered that each element of public space and private space has been developed as an architectural type that makes a group by repetitive arrangement and it found out a possibility that can make up problems overlooked in modem architecture through development and change.
