As a response to the recent increase in the Interest in environment friendly interior finishing materials, the purpose of this study is to compare the awareness of environment friendly interior finishing materials between interior designers and housewives, as representatives of two different consumer groups, and to examine how the preferences between them differ. The study participant group for this research consisted of 80 interior designers working in Gwangju, and 166 housewives who were residents of a number of apartments in Gwangju. Self administered questionnaires were provided to the participants and were then collected. Unpaired t-tests and $x^2$ tests were used to compare the prevalence of epidemiological factors and the variables that revealthe awareness and the preference between the two groups. While it was expected that both groups would source information using the internet, the housewives group showed a tendency to also seek advice from others in the selection of environment friendly interior finishing materials. Interior-designers considered the high price and the lack of diverse products as the most serious problems involved in selecting environment friendly interior finishing materials. Interior-designers chose design, color and long-term use, and the method of maintenance as standards by which to choose interior materials in general, while the housewives considered 'environment friendly' as the most important standard. Both groups however favored environment friendly materials. There was no difference between the two groups in terms of their belief in the need to trust a well known brand name and in the importance of a Green-label placed on interior finishing materials such as wallpaper, paint and laminate flooring.

This paper provides a social knowledge for pragmatic application guidelines of the interior finish materials within apartment houses, based on both the awareness of practitioners and as it applies to the realities. For this purpose, a series of the questionnaires survey on the awareness of interior finish materials in recently-constructed and remodeled apartment houses was performed, which has extended its probe into the awareness of architectural practitioners. The questionnaires asked practitioners how much they desire sustainable finish materials and the difference in various parties were analyzed and compared, formulating the pragmatic solution in the determination of interior finishes. Comparative analysis of the awareness of construction specialists, interior designer, architectural environmental researchers on environment-friendly finish materials showed that all parties were right to recognize the significance of sustainability in interior finishes. Practitioners believed that occupants must bear the additional expense for the environment-friendly finish products. Also, the results tell that the amount used of environment-friendly products increases as expertise on sustainability in interior finishes rises.

Phytochemicals have been considered as alternatives for synthetic fungicides because of their biodegradability and low toxicity. In this study, we found that the methanolic extract of Corydalis ternata suppressed the development of plant diseases caused by Puccinia triticina and Colletotrichum coccodes. As the antifungal substance, three isoquinoline alkaloids (dehydrocorydaline, stylopine, and corydaline) were isolated from C. ternata. These active compounds also exhibited in vivo antifungal activity against P. triticina and C. coccodes. Taken together, our results suggest that C. ternata and its active compounds can be used to control plant diseases.

Anthracnose caused by Colletotrichum gloeosporioides, which is one of the major diseases of red dates, causes severe damages in jujube (Zizyphus jujuba Miller) production in Korea. This study was done to evaluate the inhibition of anthracnose occurrence and pathogen growth by the treatment of environment-friendly materials such as a Bordeaux mixture and loess-sulfur mixture and by defense-response signaling in jujube. The in vitro test of the environment-friendly materials and signaling molecules that were routinely applied did not exhibit any antifungal activities against the pathogen for jujube anthracnose. The Bordeaux mixture and loess-sulfur mixture at a two-fold concentration showed inhibition zones that were 16.0 and 20.3 mm in diameter, respectively. In the pathogen inoculation test with detached jujube tree leaves, while treatment with the environment-friendly materials diluted by half showed no inhibition of lesion development, they did show inhibition of lesion development when they were routinely applied to the leaves. In detached jujube fruits inoculated with the pathogen, better suppressive effects by the treatment of the environment-friendly materials were seen in the fruits at a young stage rather than in the ripening stage. The in vivo test with jujube trees in pots showed that the treatment of salicylic acid (1 mM) resulted in the best suppressive effects against lesion development. The results suggest that it is possible to manage the incidence of anthracnose by the treatment of environment-friendly materials such as the Bordeaux and loess-sulfur mixtures and signaling chemicals such as ethephon, hydrogen peroxide, methyl jasmonate, and salicylic acid in jujube trees and fruits. Consequently, these findings suggest that environment-friendly materials and defense response signaling molecules could be used as suitable candidates for sustainable agrochemicals to manage anthracnose in jujube production.

In 2000s, the interest of ROHAS has been increased and the environmental problem has begun to be discussed as the environmental and global value, not the individual perspective. And the standard of value for eco-friendly awareness has been expanded to the economic category. The trend of eco-friendly fabric can be divided into 3 periods depending on the property. The period for natural fabric with visual effects(2002~2004) can be summarized as the creation of natural shape using the natural image, the interaction of cotton and the technology from the visual perspective. In the period of functional conjunction with eco-friendliness and technology(2005~2008), the eco-friendly awareness through the conjunction of technology and nature and the re-cycling, and the responsibility to the environment had been increased. In the period of sustainable development for nature and environment(2009~2011), it showed the conjunction with nature and the integration with technology and eco-friendly issues. Therefore, the characteristic of eco-friendly trend in fabric since 2000 can be said; firstly, the high-quality fabric has been developed with technological development for the functional progress. Secondly, the ethical creativity has been displayed with the development and utilization of eco-friendly recycling materials. Thirdly, the materials reflected with eco-friendly issues have emerged.

With people's awareness of environment-friendly buildings recently increasing, there is a need to develop environment-friendly construction materials to reduce indoorair pollution levels. Thus, efforts to develop loess finishing materials that can replace the finishing materials currently being used (e.g., gypsum boards and chemical products) are underway. An analysis of the characteristics of domestic loess products,however, revealed that the cracks on loess products can be lessened and their strength can be improved by adding chemical ingredients to them. Thus, this research sought to use 100% natural materials and to develop loess finishing materials. In the experiments that were conducted in this study, appropriate mixture ratios of loess and sand/silica sand were found, and cracks and contraction ratio changes in samples were analyzed by differentiating the ratios of natural ingredients, such as lime, fine jute threads, gypsum, and jute cuttings. Loess'particle size distribution was found to have a high correlation with loess decoration, and it was discovered that the mixture of lime and fine chute threads could improve the contraction ratio. Through this study, which made use of natural ingredients, environment-friendly construction materials that can exercise the original function of loess were developed.

This study mainly aims at suggesting plans applicable to the outdoor of environment-friendly communities in Korea by leveraging more natural conditions and materials when creating an outdoor biotop for an environment-friendly community and generating material types and development techniques enabling a natural circulation system. To this end, materials used in the outdoor of environment-friendly communities and traditional residential areas in Korea and biotop materials found in natural areas were examined. First, when the case examples of environment-friendly communities were reviewed, biotop spaces and materials that may function as habitats were hardly found. Materials used in biotop were mainly man-made structures made of artificial or processed materials, such as concrete, stones, bricks, woods and steels. Meanwhile, the outdoor space of traditional Korean villages had stone walls, soil walls, rock piles and composite piles, which composed of natural materials such as rocks, soil and plants, that naturally formed porous spaces along with the introduction of plants and provided habitats for a variety of insects. In natural areas, naturally created biotop spaces, such as rock piles, log piles, old tree deployment, branch piles, hay stacks and defoliated leaves, were found. Meanwhile, when spaces and materials available for biotop creation were reviewed to create an environment-friendly residential complex, they were divided into fences and hedges, green spaces between parks and residential buildings, ponds and waterscape spaces, zones separating pedestrian walks and roadways, breast walls and slope boundary, plant box and pergola. For each space, materials used for creating biotops and that were found in traditional Korean residential areas and natural areas were applied and suggested.
