In the HEVC CABAC, the probability model is updated after a bin is encoded and next bin is encoded based on the updated probability model. Conventional CABAC encoders can encode only one bin per cycle, which cannot increase the encoding throughput. The probability model does not need to be updated in the bypass bins. In this paper, a HEVC CABAC encoder is proposed to increase encoding throughput by parallel processing of bypass bins. The designed CABAC encoder can process either a regular bin or maximum 4 bypass bins in a cycle. On the average, it can process 1.15~1.92 bins in a cycle. Synthesized in 0.18 um technology, its gate count, maximum operating speed, and the maximum throughput are 78,698 gates, 136 MHz, and 261 Mbin/s, respectively.

The purpose of this study is to examine the expression techniques and methods of Upcycling fashion brands and designers who have focused on Upcycling, and have found success. The study used collected literatures, press releases, and Internet searches using the word, 'Upcycling' in order to investigate the design characteristics and to set up criteria to classify the material expression techniques found in Upcycling fashion design. The results are as follows: Firstly, according to the result of analyzing the product images of Upcycling fashion design, the most frequently used expression methods are deconstruction and reorganization, $d{\acute{e}}paysement$, and assemblage/collage. Deconstruction and reorganization is used to make most of the Upcycling fashion design products using recycled materials. It is one of the ways to create new value that transcends the value of the previous item. Secondly, Upcycling fashion design's expression techniques generally attempt to use recycling material diversely to complement the recycling material that is limited in some way to the purpose of clothing. In this process, we can find expression techniques used to bring out) the characteristics of Upcycling fashion design. Patching, adding, cutting, folding, or weaving is the technique mainly employed.

This study explores the effect of moral identity on attitude toward and purchase intention of upcycled fashion products by comparing purchasers and non-purchasers. Data from 127 purchasers and 307 non-purchasers collected through a survey was analyzed using descriptive statistics, confirmatory factor analysis, model invariance check, and multiple-group comparison tests using Amos 23.0. Results indicate consumers with purchase experiences of upcycled fashion products showed a higher level of moral identity (internalization and symbolization), positive attitude toward upcycled fashion products, and purchase intention than did consumers with no purchase experience. In model tests, internalization affected attitude toward purchasing upcycled fashion products, whereas symbolization affected purchase intention, regardless of purchase experience. The effect of symbolization on purchase intention was consistent with prior studies focusing on charity behaviors that are highly visible to others. These findings demonstrate that fashion products are visible and symbolic, so it should be carefully considered in ethical consumption studies. From these results, researchers may obtain insights on the process of how consumers apply moral identity to their purchase intention regarding upcycled fashion products. Likewise, marketers may enhance satisfaction of consumers with a high level of symbolization by putting special tags and logos that clearly highlight the products' upcycled nature.
