The hot-wave of campaign for fashion brands has itself become a fashion trend now. In order to participate in this popular trend, every brand has launched a new campaign of developing T-shirts each season with a social issue as the design concept. Such a campaign plan is related to the brand's image-making. Each brand has its own slogan based on various themes related to social issues. Since the environment is the hottest social issue these days, most campaigns' T-shirts also focus on the image of environmental-friendliness. The purpose of this study is to elucidate environmentally-friendly fashion culture in daily life so that "environmental-friendliness" would be positively cognized by people in everyday life. For that, the design of these T-shirts following the environmental campaign will be developed and their utilization potential will be clarified. The detail contents of the study are as follow. First, the meaning of the environmental campaign and trends of environmental campaigns in Korea and overseas will be explored in order to identify their theoretical contents. Second, the environmental campaigns will be classified by case. Analysis of the expression and characteristic of each case will determine the utilization plan. Third, design directions will be suggested based on the characteristics produced from the case study. As the study conclusion, five environmental campaign T-shirts will be produced.

2015년 말 신기후변화협약인 파리협정(Paris Agreement)이 체결됨에 따라 우리나라의 환경정책에도 많은 영향을 미칠 것으로 보인다. 우리나라의 전체 이산화탄소 배출량의 42%를 차지하고 있는 건설업은 그동안 환경문제를 개선하기 위하여 다양한 정책을 펼쳐 왔지만, 친환경건축물 인증에 해당하는 프로젝트 외에는 소극적 적용에 그치고 있다. 이는 대부분의 친환경 관련제도가 건축시설물을 위주로 하기 때문인 것으로 판단된다. 따라서 건축 뿐 아니라 토목시설물에도 광범위하게 적용될 수 있는 새로운 친환경 설계평가모델이 필요하다. 본 연구에서는 기존의 VE모델을 기반으로 시설물의 친환경성, 잠재적인 환경오염 개념과 환경위험성을 평가 할 수 있는 새로운 요소를 추가하여 의사결정자가 설계단계에서 친환경에 효과적인 대안을 선정할 수 있도록 친환경 설계평가 모델을 제시 하였다. 원안인 블록식 옹벽과 대안인 현장타설 옹벽을 대상으로 사례분석을 실시한 결과 대안의 친환경가치값이 원안보다 1.026배 높게 산출되었다. 본 모델이 설계단계에서 활용된다면 환경친화적인 시설물의 건설뿐 아니라 탄소배출량의 감축에도 기여할 것으로 기대된다.

Livestock farmers are using animal carcasses to dispose of the carcasses of livestock that have died of natural causes or disease. Most of the existing livestock carcass processors are mechanical in their structure without considering the environment. It has a function of sterilizing dead bodies at high pressure after processing them and causes environmental problems such as carbon monoxide emissions. If livestock carcasses occur, livestock farmers have to purchase their own livestock carcasses or entrust them to the outside world, which is costly. For this reason, the possibility of environmental pollution, infectious diseases, and spread has been increased recently by frequent dumping of dead bodies. The carcass of livestock mixed with manure not only serves as a medium for infectious diseases but also needsto be buried on a large scale as foot-and-mouth disease and avian influenza spread. As a result, the possibility of environmental pollution, such as contamination of groundwater, is increasing, so research is needed to protect and improve the environment. We aim to improve the process of processing livestock carcasses and purify the agricultural environment through development results on the form, structure and function of eco-friendly livestock carcasses. Its shape is applied with naturalshapessuch asstones and seeds. The material used in the dead body processis a brown beggar biocouple and is applied with an eco-friendly industrial animal recycling process. As a result of the study, it is expected to improve odors and the environment, and to be used as data to improve and help the livestock industry in the future.

Serratia marcescens W1, isolated from cucumber-cultivated soil in Suwon, Korea, evidenced profound antifungal activity and produced the extracellular hydrolytic enzymes, chitinase and protease. In order to isolate the antifungal genes from S. marcescens W1, a cosmid genomic library was constructed and expressed in Escherichia coli. Transformants exhibiting chitinase and protease expression were selected, as well as those transformants evidencing antifungal effects against the rice blast fungus, Magnaporthe grisea, and the cucumber leaf spot fungus, Cercospora citrullina. Cosmid clones expressing chitinase or protease exerted no inhibitory effects against the growth of fungal pathogens. However, two cosmid clones evidencing profound antifungal activities were selected for further characterization. An 8.2 kb HindIII fragment from these clones conditioned the expression of antagonistic activity, and harbored seven predicted complete open reading frames(ORFs) and two incomplete ORFs. The deduced amino acid sequences indicated that six ORFs were highly homologous with genes from S. marcescens generating pyrroloquinoline quinone(PQQ). Only subclones harboring the full set of pqq genes were shown to solubilize insoluble phosphate and inhibit fungal pathogen growth. The results of this study indicate that the functional expression of the pqq genes of S. marcescens W1 in E. coli may be involved in antifungal activity, via as-yet unknown mechanisms.
