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.

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.

This study is the 2nd report following "A Study on the Characteristics of Material in the Korean Up-cycling Fashion Brands (Part I)" that handled the development of upcycling props using the characteristics of upcycling material. The 2nd report analyzed product types and materials focusing on 21 foreign upcycling fashion brands. It analyzed the characteristics of upcycling fashion materials using the case analysis of coffee bean bag and waste denim based on external characteristics and internal characteristics. We then classified the external characteristics into environment/economic feasibility and availability/mixture and the internal characteristics into historicality/story and originality/scarcity. Five bags were designed and produced for the actual commercialization of fashion products based on such characteristics of materials, with the use of coffee bean bags and waste denim as upcycling materials. This study is differentiated from existing research by its suggestions for the utilization of fashion product upcycling coffee bean bags and waste denim. Also, upcycling fashion products could be competitive products in eco-friendliness and originality that can be a driving force for the sustainable development of fashion industry through the differentiation of existing fashion products.

Plastic's ease of processing drives its growing production, resulting in a surge of plastic waste. Addressing this issue, catalytic upcycling emerges as a promising remedy. Various metals (Ru, Pt, etc.) and supports (TiO₂, CeO₂, etc.) have been employed for the chemical recycling of polyolefin plastics. Strategies to enhance liquid fuel selectivity and minimize methane include manipulating particle size, introducing heterogeneous metals, and tuning support characteristics. Simultaneously, endeavors to optimize catalysts by reducing precious metal usage were pursued. This study explores enhancing economic viability in hydrogenolysis and hydrocracking reactions, underscoring the potential of catalystdriven upcycling to tackle plastic waste.

The purpose of this study was to provide basic information on the development of local governments and upcycling industries that want to establish centers in the future. The study investigated the current situation and programs of domestic upcycling centers for regional sustainable growth. As a result of comparing and analyzing the programs operated by the upcycling centers by region, they could be classified into culture and arts experience programs, resource circulation experience programs, and environmental culture education programs according to the nature of the operation programs that are more focused on in addition to the experience and education programs reflected by each center. Among the upcycling materials and items used in the operation program, fashion-related education was being operated in a more diverse manner in the area of culture and arts experience programs. As a result of the analysis, it was found that it was necessary to establish a smooth material supply network, develop an in-depth step-by-step upcycling fashion education program, and strengthen the upcycling center program using regional characteristics. The results of this study are significant in that they provide the local governments with basic information for the establishment of upcycling centers in areas where the upcycling centers have not been established. In addition, this study presents the types and directions of programs necessary for establishing upcycling centers in the future.

The purpose of this study is to develop and implement a step-by-step upcycling fashion education program that can be utilized within the local community. This program aims to provide basic data by analyzing the current state of community-based upcycling projects and upcycling center programs. To achieve this, the study first examined the meaning and value of upcycling in fashion through literature research and explored upcycling projects and programs in connection with local communities. Subsequently, an upcycling fashion education program platform was developed and applied using the design thinking process. The program involved students from nine high schools in Gwangju Metropolitan City. Depending on the school's circumstances, the time and difficulty level of the upcycling education program were adjusted accordingly. A unique eco-bag making kit, using jeans developed in this study, was employed. Following the completion of the program, a satisfaction survey was conducted among 167 participating students from the high school community class. The findings indicated that the majority of students experienced an increased appreciation, attraction, and interest in upcycling products. They also demonstrated an understanding of the environmental impact of upcycling products and the distinction between upcycling and recycling. It is believed that the educational program developed in this study can promote ethical fashion and foster a sense of value-based consumption. This program can be customized and flexibly adapted to different educational levels and institutional characteristics, making it accessible to a wide range of learners.

Christopher Nemeth is a designer who combines characteristics of a pioneering upcycle design and deconstructionist design with fabrics, waste clothing, and pieces of fabric recycled in the 1980s. By hommaging his work from the Louis Vuitton 2015 F/W collection, Kim Jones is once again becoming a source of design inspiration in an era where upcycling fashion is attracting attention. Accordingly, an upcycling design approach might appeal to the MZ generation. Christopher Nemes' design presented in this study as a representative fashion designer of dismantling upcycling is basically based on dismantling. It can also be interpreted as dismantling upcycling design because it uses used clothing, waste clothing, and discarded fabrics as materials. This study examined main techniques of upcycling fashion design and derived characteristics of Nemes design as "deconstructive techniques using free lines of construction," "recycling upcycling vintage materials and clothing accessories," and "using handcrafted techniques of artistic sensibility." By applying Nemes' dismantling upcycling technique, four designs were developed for men's top and bottom sets for targets in their 20s and 30s to suggest the commercialization possibility. This study is meaningful in that it proposes a methodical alternative to the new deconstructionist upcycling design that can show Nemes' aesthetic characteristics, creative perspective, and personality by modernly reinterpreting the deconstructionist upcycling technique extracted through analysis of fashion designer Christopher Nemes' design. In particular, by actually producing the work and confirming whether the design technique can be implemented, the value as a fashion product that can be sold is realized.

This research focuses on the development of upcycled denim fashion designs, whichis a more specific category within general upcycled fashion design. Characteristics of upcycled fashion design, which has been identified previously by researchers, include the following traits: environmentality, uniqueness, aesthetic appeal, availability, convertibility, and deconstructivity. The expression principles include recycling, substitution, recombination, and reduction. The result of the analysis of the denim fashion design characteristics, which is based on the theoretical analysis, has found. The external expression pattern consists of the deconstruction and reconstitution of materials, the avant-garde style and convertibility, the ability to mix and match materials and techniques, the production of zero waste, and the use of layering. The expression techniques used included decomposition, depaysement, weaving, cut-off, collage, assemblage, overlapping, connecting, attaching, and stitching. The inner meanings were identified as economicality through recycling, convertibility through rearranging, and the rarity and value of hand-made products. The result of the research applying the identified characteristics are as follows. First, developing and creating designs using modified denim and sub-materials with various expression patterns and techniques could provide completely new images unlike existing denim products. Second, modifying the details while maintaining the basic format of denim clothing could provide unique and new possibilities for upcycled denim fashion design. Third, environment-friendly models with creative designs were developed by recycling used denim materials. This reduced waste and energy while maximizing the use of resources. This study expects contribute to upcycled fashion design research by recognizing the unique characteristics and value of denim material.
