환경에 대한 범세계적인 문제와 관심이 고조되는 가운데 자동차 산업에서도 친환경 소재로의 전환이 가속화되고 있다. 자동차 산업에서 친환경 복합재료는 차량 내부 및 비 구조 부품에 주로 사용된다. 특히 천연섬유 복합재료는 차량의 경량화로 연료 소비와 온실가스 배출을 줄이는데 도움을 주며 재활용이 가능하고 우수한 열적 특성과 내구성을 가지고 있어 자동차 내장 부품에 적합하다. 아울러 생산 비용 절감과 지속 가능성은 천연섬유 복합재료의 주요 장점이다. 친환경 복합재료 시장은 2022년부터 2030년까지 연평균 성장률 15.3%로 864억 3천만 달러 규모로 성장할 것으로 기대되며, 천연섬유 복합재료 시장은 2023년부터 2028년까지 연평균 5.3% 성장해 4억 2,400만 달러에 이를 것으로 예상된다. 본 리뷰 논문에서는 천연섬유 복합재료를 중심으로 차세대 자동차용 친환경 복합재료의 연구 동향과 실제 자동차 산업에서의 적용에 대해 탐구한다.

As the construction industry develops, environmental pollution gets increasingly serious, giving damage including the increase of incidence of respiratory diseases and skin diseases among children with weakened immune systems, rather than adults. In daycare centers, infants and children spending much of their time, have high frequency of contact with the interior floor finish material. However, the majority of the child care centers don not use eco-friendly flooring but ordinary monorium flooring, because the initial investment cost of the eco-friendly flooring is higher than ordinary monorium flooring. Therefore, in this study, life cycle costs including the initial investment cost of the eco-friendly flooring and ordinary monorium flooring were calculated, demonstrating that the eco-friendly flooring is more economical than ordinary monorium flooring in terms of life-cycle cost. In addition, the analysis of the environmental performance also showed the excellence of the eco-friendly floor finishes. It is expected that the use of the eco-friendly floor finishes will increase due to their excellence in the aspect of life cycle cost and eco-friendly performance, through this study.

본 연구에서는 친환경유기농자재를 사용하여 작물을 재배하는 농업인을 대상으로 설문조사를 시행하여 친환경유기농자재의 사용실태, 부작용 경험 및 친환경유기농자재의 안전성에 대한 인식도 등을 조사하였다. 조사결과 친환경유기농업에 종사하는 농업인이 친환경농업에 참여하는 가장 큰 이유는 안전농산물을 생산하기 위한 것으로 나타났다. 또한 친환경유기농자재의 안전성에 대해 보통이상으로 높게 인식하고 있었으며, 재배면적이 많은 농업인이 재배면적이 작은 농업인에 비해 친환경유기농자재의 안전성에 대한 인식이 더 낮았다. 친환경유기농업 인증을 받은 응답자의 23.6%와 인증을 받지 않은 응답자의 33.8%가 부작용을 경험함으로써 친환경유기농업 인증을 받은 농업인의 부작용 경험 비율이 낮았다. 친환경유기농자재 사용으로 인한 부작용의 종류는 주로 '눈가려움', '손발가려움', '피곤함'으로 나타났으며, 부작용을 경험한 사람($3.79{\pm}1.15$)이 경험하지 않은 사람($4.15{\pm}0.86$)에 비해서 사용방법을 준수하는 비율이 유의적으로 낮게 나타남에 따라 부작용의 발생 여부는 포장지에 기재된 사용방법 준수 행위와 밀접한 관련이 있음을 알 수 있다. 이러한 결과를 근거로 해서 정책 및 교육부문의 개선방안을 제안하기 위해서는 농업인을 대상으로 하는 보다 정밀한 의견 수렴 등의 연구가 필요할 것으로 생각된다.

The chief aim of this study is to prepare the rational alternative plan of the environmental friendly intoner design which can improve sick house syndrome of an apartment house and clarify future-development and the method proposal of use activation and point out the present problem depended to investigate development and the use actual condition of domestic environmental friendly interior materials related in-and-outside-the-country example on a foundation about the various precedence researches on environmental friendly interior materials. The study was witten at first the concept of the environmental interior design which leads environmental friendly charactenstics of material, a interior design, and construction, at the first in the conceptual definition of sick house syndrome. and then it was introduced the present condition of domestic environmental interior materials, interior design and construction and an environmental regulation and standard of in-and-outside-the-country In Conclusion, it may try to present comprehensive analysis and an expansive alternative plan.

Nowadays, according to many studies, indoor space's pollution level is two to ten times higher than outdoor space's. This result arouses our attention. The major causes of deterioration of indoor air quality are the lack of ventilation caused by draught-proofing and insulation construction, and harmful chemical substances emitted from building materials, office machine and furniture. Therefore, we are continuing research to find the method for healthful house and production of many forms of well-being goods. However, because of exaggerated advertisements and the lack of accurate information, consumers choose the products whose performance is not verified. Therefore, this study investigates the actual conditions of pollution by building materials and the extent of the health damage by this pollution, and suggests the method for minimizing indoor pollution in aspect of indoor environment control and the use of environment friendly materials. But the building materials presented in this study are limited to the environment friendly construction materials that are in circulation In domestic market because this research is primarily aimed to give domestic consumers the standard for selecting this materials.

The most important factor when designing coastal and offshore concrete structures is durability. However, concrete in marine environment is exposed to physical and chemical deterioration of seawater, which might easily lead to low quality. The purpose of the present study is to understand advantages of adding ground solidificaton materials by comparatively analyze the seawater resistance of general concrete and environmental-friendly ground solidification materials.

The green body of WC-Co cemented carbides containing polymeric binders such as paraffin, polyethylene glycol (PEG), and polyvinyl acetate (PVA) are prepared. The green density of the WC-Co cemented carbides increases with the addition of binders, with the exception of PVA, which is known to be a polar polymeric substance. The green strength of the WC-Co cemented carbides improves with the addition of paraffin and a mixture of PEG400 and PEG4000. In contrast, the green strength of the WC-Co does not increase when PEG400 and PEG4000 is added individually. The compressive strength of the green body increases to 14 MPa, and the machinability of the green body improves when more than 4-6 wt% paraffin and a mixture of PEG400 and PEG4000 is used. Simultaneously, the sintered density of WC-Co is as high as 99% relative density, similar to a low binder addition of 1-2 wt%.

Pulp mold is one of the famous environmental friendly materials, which made from re cycled materials such as old newsprints through the environmental friendly processes. Furthermore, the used pulp mold can be easily recycled and the pulp mold itself is biodegradable. However, the higher cost and some deficiency in physical properties of pulp mold have been considered as issues to be overcome for a substitute for polymeric packaging materials such as EPS (Expandable Polystyrene). The way for the optimization of a pulp mold mill was proposed in this report. The possible reduction of drying energy was calculated by using a computer simulation method, which could Provide the detailed information about mass balance of overall process. The simulated results showed a great possible curtailment of production cost by improving the forming systems, for example, increasing the temperature and the dryness of a wet pulp mold.
