PURPOSES : This study determined the optimal usage rate of RAP (reclaimed asphalt pavement) using cold central-plant recycling (CCPR) on a road-surface layer. In addition, a mixture-aggregate gradation design and a curing method based on the proposed rate for the surface-layer mix design were proposed. METHODS : First, current research trends were investigated by analyzing the optimum moisture content, mix design, and quality standards for surface layers in Korea and abroad. To analyze the aggregate characteristics of the RAP, its aggregate-size characteristics were analyzed through the combustion asphalt content test and the aggregate sieve analysis test. Moreover, aggregate-segregation experiments were performed to examine the possibility of RAP aggregate segregation from field compaction and vehicle traffic. After confirming the RAP quality standards, coarse aggregate and fine aggregate, aggregate-gradation design and quality tests were conducted for mixtures with 40% and 50% RAP usage. The optimum moisture content of the surface-layer mixture containing RAP was tested, as was the evapotranspiration effect on the surface-layer mixture of the optimum moisture content. RESULTS : After analyzing the RAP recycled aggregate size and extraction aggregate size, 13-8mm aggregate was found to be mostly 8mm aggregate after combustion. After using surface-chipping and mixing methods to examine the possibility of RAP aggregate segregation, it was found that the mixing method contributed very little for 3.32%, and because the surface-chipping method applied compaction energy directly as the maximum assumption the separation ratio was 15.46%. However, the composite aggregate gradation did not change. Using a 40% RAP aggregate rate on the surface-layer mixture for cold central-plant recycling satisfied the Abroad quality standard. The optimum moisture content of the surface-layer mixture was found to be 7.9% using the modified Marshall compaction test. It was found that the mixture was over 90% cured after curing at $60^{\circ}C$ for two days. CONCLUSIONS : To use the cold central-plant recycling mixture on a road-surface layer, a mixture-aggregate gradation design was proposed as the RAP recycled aggregate size without considering aggregate segregation, and the RAP optimal usage rate was 40%. In addition, the modified Marshall compaction test was used to determine the optimum moisture content as a mix-design parameter, and the curing method was adapted using the method recommended by Asphalt Recycling & Reclaiming Association (ARRA).

In this study, the effects and the interactions of water content, SP-binder ratio, and water-binder ratio on the workability performance of concrete were investigated. The experiments were designed based on flatted simplex-centroid experiment design modified from standard simplex-centroid one. The data gotten from the design was used to build the concrete slump model using neural networks. Research reported in this paper shows that a small number of slump experiments can be performed and meaningful data obtained with the experiment design. Such data would be suitable for building slump model using neural networks. The trained network can be satisfactorily used for exploring the effects of the components and their interactions on the workability of concrete. It has found that a high water content and a high SP/b ratio is essential for high workability, but achieving this by increasing these parameters will not in itself guarantee high workability. The w/b played a very important role in producing workability and had rather profound effects; however, the medium value about 0.4 is the best w/b to reach high slump without too much effort on trying to find the appropriate water content and SP/b.

Postmodernism, the theory and philosophy that swayed the world in the late 20th century, can be interpreted in various ways as a critical reaction against modernism as well as, in one way, the logical extension of modernism itself. Thus, an extensive understanding of the social and temporal background of the birth of postmodernism and a macroscopic and correlative approach toward the related artistic circles, especially art, were carried out before a formative discussion on the furniture design of postmodernism. Postmodemism in the field of furniture design shares the history of birth and spirit with Memphis, the progressive design group established by Ettore Sottsass in Milan, 1980. This study identifies the formative features of pestrnodernistic furniture design around those works that express the trend of postmodernism, in particular, chairs, as well as the designers who participated in the first Memphis exhibition at the Milan Furniture Fair. By identifying such features, the correlation between postmodemism and those features expressed in the works of postmodernism paintings were examined. The works of Anselm Kiefer, a German nee-expressionist who became famous through the Venice Biennale 1980, and five young Italian trans-avant garde authors were selected as the scope of this case study. The characteristics of postmodernism in modern art were analyzed in terms of themes, shape, and content and were derived as follows; Firstly, borrowed and past-oriented themes, secondly, deconstructive, atypical, plural, emotional, and intuitional shapes, and thirdly, basic, metaphorical, and abstract content, The formative characteristics of chair design in postmodemism furniture design are as follows; Firstly, deconstructive, symbolic, and abstract shapes, past-oriented, reactionary, and primitive colors and closing, as well as the characteristic of delivering commercial and metaphorical messages. The subjects and motives of art have been succeeded by the characteristics of color and closing in furniture, the shape and techniques of fine arts by the characteristics of furniture shape, and the content of art by that of furniture. They share key words and characteristics.

The demand of digital broadcasting via networks has increased slowly in spite of the development of bidirectional broadcasting service technology and the effort of revitalization are actively performed nowadays. There are some reasons that the content differentiation is necessary. First, bidirectional digital broadcasting has no special content that attracts public attention. Second, bidirectional video content such as UCC is expected to revitalize economy due to simplification of authoring tool and user's desire to communicate interactively. So this paper proposes the data broadcasting sub-content architecture model by scenario using original data broadcasting content. At the same time, we design the content object metadata schema from the analysis of original data broadcasting content. It is restricted by 25 metadata in order to make it more smoothly working contents under the ubiquitous environment. This proposal is expected to affect the revitalization of content development and find out new sub-content model by rework original content.
