Recycle fashion is suggested to the suitable alternative of the environmental problem and the exhaustion of natural resources. The purpose of this study is focused on trying to comprehend between design characteristics and aesthetic values of recycle fashion design and those from fashion brands, fashion designers, and the public. For such purpose, 1553 photos of recycle fashion design which appeared in web-site, newspaper, fashion magazines between 2002 and 2007 were analyzed. Method of analysis did content analysis. The results of the research can be summarized as follows. First, design characteristics of recycle fashion were expressed by Junk Recycle Look, Vintage Recycle Look, Contemporary Recycle Look, Artisanal Recycle Look. Second, the expression methods of recycle fashion were presented reuse, reform, and regeneration. Third, aesthetic values of recycle fashion can be explained by the promotion of environment, the variableness, and the deconstruction.

Recently, the study to reduce and recycle industrial waste is underway vigorously in the various fields of industry according to the conservation of environment and resources. In construction work, the disposal problem of its waste and environmental disruption have already been serious all over the world. However the recycle of waste concrete is still at an early stage, recycled aggregate from waste concrete have only used those as subsidiary road fillers. The research institute and the company make the study that it is about the properties of recycled aggregate and those structural capacity since 1990. Through the experimentation last year, we know that strength and fluidity of recycle cement are inferior to normal cement, and admixing aggregate powder deteriorates its strength. The purpose of this study is to search for appropriate heating time and to improve performance of the recycle cement while heating hardened cement which is crushed, we investigate separating aggregate from hardened cement by preheating and improvement of strength and fluidity inrecycle cement which contains admixture.

This study provides basic materials about setting pH standard of recycle aggregate by analysing pH change from elution time, type of solvent and ratio of solvent with existing experiment methods about recycle aggregate. Also it has purpose of evaluating impact of recycle aggregate outflow's pH on actual environment by building a model that is similar to condition of recycling recycle aggregates. pH of recycle aggregates seemed to not change a lot by time with each experimental method. To evaluate degree of generation by recycle aggregates in natural state, natural water with distilled water seemed be useful to use as solvent. Also it was possible to confirm that there is a difference between actual pollution in natural state by only pH of recycle aggregates.

동제련 공정중 고품질의 전기동을 효율적으로 생산하기 위해서는 Anode중에 적정량의 비소(As)가 필요하다. 그러나 Cu가 약30% 함유되어 있는 동정광에 함유된 비소는 Smelting Furnace 용련과정에서 비소 특성상 약 70%가 Offgas로 휘발되어 황산공장으로 유입 처리되고, 나머지 30%만 아노드(Anode)로 유입되므로 별도로 전련공정에서 발생된 Cu-Cement(비소 함유)를 정제로에 Recycle 하고 있으며, 부족시 추가로 비소 Source를 구입하여 정제로에 투입하고 있다. 이를 효과적으로 해결하기 위하여 현재 위탁처리를 하고있는 As가 함유된 폐수처리 2차 중화시 발생된 2차 Cake 60W.T/D중 30W.T/D를 기존 Converter Slag 건조용 Rotary Dryer를 이용하여 Converter Furnace에 Recycle 함으로써 전련 Anode에 필요한 비소를 공급하고, 또한 2차 Cake에 혼입되어 있는 CaO 활용으로 부재료 절감, 유가금속(Cu등) 회수등 및 2차 Cake 위탁처리비용을 절감하며, Cu-Cement는 Smelting Furnace에 투입하여 정제로 투입시 발생되는 문제점들을 동시에 해결코자 한다.

Laboratory-scale membrane bioreactor added alum into the anaerobic basin as a flocculant and adsorbent was carried out to find removal efficient of nitrogen and phosphorus components in the mixed liquid and weather or not maintaining the stability for the permeate flux and pressure at various internal recycle conditions. It was found that denitrification efficient of maximum 65% was obtained when the ratio of internal recycle was 3Q. Additionally when the ratio of internal recycle was fixed at 3Q, $BOD_5$ and T-P concentration of permeate was much more reduced compared to not added alum in anaerobic basin but T-N concentration of permeate was relatively increased. In case of added alum as the flocculant and adsorbent in anaerobic basin, the permeate flux was maintained above $10{\ell}/m^2/hr$ but the permeate pressure was relatively higher than alum was not added in anaerobic basin.

For a sustainable development, the resources circulation system should be established and required alternative logistics area of enterprises. In this paper, we are to suggest a direction through analysis effects, and reduce, recycle, reuse factor of transportation, material handling, packing, information, management in logistics function, and effects of logistics organization on Firm Performance. We found significant correlations between the constructs extracted above, and between the constructs and firm's performance. This study was conducted with the subjects of manufacturing enterprises with concurrent reviews of literature and statistical analysis, and the meaning of this study would be the analysis of the influencers of the resources circulation system.

This study has cross checked the change of internal sludge-recycle in Anaerobic-Digestion, and researched about not only the improvement of Bio-gas production from the digested sludge but also the efficient method of sludge minimization. Ultimate object of the study is to reduce the amount of sludge by the improved efficiency of contact with the organic-matter and the microbes in Anaerobic-Digestion. The sludge-recycle fluidized sludge layer and raised the activity of the sludge, the optimal sludge-recycle ratio, VS and COD removal ratio were 1,000%, 28.2% and 27.7%, respectively. Through these results of this study, it may be of use to treat waste sludge by the sludge-recycle ratio in terms of minimization and circulation of resources.

This study have cross checked the change of internal sludge-recycle in Full-scale Anaerobic-Digestion, and researched about not only the improvement of Bio-gas production from the digested sludge but also the efficient method of sludge minimization. Ultimate aim of the study is to reduce the amount of sludge by the improved efficiency of contact with the organic-matter and the microbes in Anaerobic-Digestion. The sludge-recycle fluidized sludge layer and raised the activity of the sludge, The sludge-recycle ratio of optimum was 500%, VS and COD removal ratio respectively appeared with 67.8% and 70.4%. Through these result of this study, it may be positive view to treat waste sludge by the sludge-recycle ratio in terms of minimization and circulation of resources.
