The purpose of this study is to review and establish the three concepts of upcycling, zero-waste fashion design, and regional sustainability through a review of domestic and international case studies. Furthermore, it will provide the theoretical basis for using upcycling as a regional sustainability practice to create zero-waste fashion design. To conduct an empirical study, we systematized the stages of the survey on waste resources in Changsin-dong, the sourcing and utilization of waste resources, the design-planning stage, and the co-production with pattern and sewing masters as a suggested practice for regional sustainability. Through this study, we propose the possibility of regional sustainability by developing and sharing the method of zero-waste fashion design. The conclusion of the study as follows: First, upcycling fashion designs can be extended to a regional sustainability practice by taking the characteristics of social design into account. Second, by providing a design development process and methodology suitable for regional sustainability application, it is helpful to revitalize regional upcycling fashion brands and communities by providing data for upcycled fashion branding. Third, as part of the revitalization project for the Changshin and Soongin areas that started in 2014, using the region’s economic, cultural, and environmental characteristics to make and sell high-value, upcycled fashion products will contribute to social and economic achievements and aid in solving regional problems.

The current study aims to analyze the process of fabric production planning in Dongdaemun Market, which is a successful model case industrial integration in South Korea. We followed the changes in perception among fabric experts, regarding their recognition of fashion trends, and the following planning and process of fabric production. We used the purpose sampling method to select participants for interview in the Dongdaemun Market, then we carried out one-to-one interviews. Our analysis reveals 4 points of importance. First, the fabric planning stage either employed the trend book swatch, or simply reused the model fabrics already available. Even though the experts felt the need to accept the latest fashion trends, very few considered the trends as positive influences in fabric planning. Whereas trend was a key element in identifying the flow of the fashion industry, there were obstacles in carrying out the study. Second, experts frequently participated in domestic fabric seminars, but not in textile exhibitions. Third, domestic and overseas market research has been performed typically at department stores, and typically at Japan. Fourth, the influx of Chinese fabrics has both positive and negative influences, such as low price, and low reliability. In conclusion, experts were less amenable to accepting the latest fashion trends. pre-requisites in real life to meet the use of the current trend of each company. More studies on the Dongdaemun Market from perspectives of practitioners are warranted.

The current research focused on exploration of a well known Korean fashion and clothing industry cluster, Dongdaemun Fashion Town(DFT). Many clothing and fashion wholesalers in DFT with various business formats are trying to obtain competitive advantages. For the empirical study, a questionnaire was developed. Items measuring descriptive statistics for each business and contractor selection criteria were included in the survey. 161 data from Employees of various wholesalers of DFT were used for statistical analysis. Majority of DFT customers were buyers of Internet shopping malls and street retail shops. 64% of them used domestic contractors for sourcing products. Most of them managed less than three contractors. Contractor selection criteria were factorized as flexibility, production ability, stability, fame and location. Wholesalers were segmented into three groups: product oriented, flexibility oriented and stability oriented groups. Group differences in terms of business practices were assessed and strategic implications were included.

The purpose of this study was to investigate and analyze continuous operation of food waste resources at Dongdaemun Environmental Resources Center and to improve the overall operation of the dry anaerobic digester facility. Korean domestic food wastes consist of 18% total solid (TS) content but food waste is difficult to utilize for dry anaerobic digestion. Other operational trouble-shooting resulted from the inherent design, construction and operation of such a biomass generation facility based on 100% utilization of dewatered cake with 35% TS concentration as feedstock, causing the accumulation of unwanted solid residues. A materials flow analysis obtained from actual operation of the anaerobic digestion facility revealed that the organic material loading rate (OLR) and its residence time were 8.3 kg-VS/m3·day and 18.3 days, which adversely affected stable operation. The OLR was occasionally > 15,000 mg/L organic acid concentration and the facility shut down. Such anomalies drastically reduced biogas production and increased organic matter loading in the wastewater, which exceeded the legally allowed concentration limit. Operation of this facility has been normalized to the targeted facility capacity of 98 m3/day based on the results of this study.

This study surveyed the human thermal responses according to the green space types. Three green space type (forest trail, residential area and central building district) were set the research sites in Dongdaemun-gu, Seoul. The physical thermal environment factors were measured while the human thermal responses were investigated. The air temperature and radiant temperature showed higher in central building area where sky view factor was 0.799 than in forest trail where sky view factor was 0.651. The skin temperatures increased according to green space type and rectal temperatures showed the highest value in central building area. The thermal sensation vote and thermal comfort showed the differences only between forest trail and central building area. These results will use as base line data on the green space type management plan for thermal environment amenity.

본 연구의 목적은 동대문 패션시장의 의류제품 품질구성요소를 알아보고, 품질개선방안을 알아보고자 하였다. 서울지역의 20대 이상 성인여성을 대상으로 편의표본추출을 하였으며, 3개의 부분으로 구성된 설문지방식으로 측정되었다. 자료 분석은 요인분석, 대응표본 t-test, 빈도분석을 실시하였다. 본 연구의 결과 의류제품 품질구성차원은 심미성, 의복 관리성, 실용성, 상징성, 개성 차원의 5개로 구성되었다. 즉 심미성은 색상, 디자인 등 미적요소를 의미하였고, 의복 관리성은 의류제품을 구성하는 세부속성들의 관리 측면을 설명하였다. 또 실용성은 활동의 편안함, 착탈의 편안함 등의 의복착용의 실용적인 측면을, 상징성은 사회적인 품위와 지위를, 개성표현은 유행성이나 상품의 차별화 항목을 의미하였다. 그리고 중요도와 만족도의 차이를 알아본 결과 개성차원을 제외한 모든 항목에서 유의미한 차이가 있는 것으로 나타났고, 중요도가 만족도보다 높게 나타났다. 격차분석 그래프 상에서 심미성은 I영역에 속하는 것으로 현 상태를 유지해야 하는 강점 항목으로 나타났다. 특히 색상은 IV영역으로 품질개선이 요구되는 속성으로 나타났다. 그리고, 상징성, 관리성, 실용성은 III영역에 속하는 것으로 나타났다.
