In 1990s, interest on Environment has been increased and Environment-oriented consumer's economic power accelerated the trend of preference for 'Environment-friendly material'. Moreover, the concept of 'Sick Building' Syndrome has been spread to the public and solution for the syndrome is required. 'Environment-friendly material'means that the material used is not harmful for the user's health, and on top of that, causes least harm to the environment during production/scrap process of the material itself. Decision of designers and architectures, as a result, is really crucial tot he environment issues. Above all, selecting the most environment-friendly material and design among possible candidates is natural and cost saving way. In the paper, couple of Evaluation Criterium for Material Selection are analyzed and objective linkage has been identified. With the result of analysis, methodology to minimize damage on environment during whole life cycle of the Interior Design has been sought for.

Sound absorbing materials used for lightweight panels and interior material are mainly made of fibroid material such as glass wool or rock wool. However these fiber type sound absorbing materials have some problems such that sound absorption could be decreased as time goes by because of durability. In addition, dust scattering from fiber type material can cause another problem in health. In this point of view, this study aims to develop environment friendly sound absorbing material using Hwangto(so called loess or yellow soil), a traditional housing material. Hwangto is natural housing material in Korea and generally known for improving indoor air quality. Hwangto panel is made to construct on the floor, wall and ceiling, and expected that there is not enough absorption. Present study tried to develop environment friendly sound absorbing material that has high sound absorption performance with good environment performance in terms of air quality. Pore rate was designed to maximize the absorption in the specific frequency bands, and two kinds of backing space were applied in order to see the effect of backing space. As a result peak frequency that has maximum absorption is going high as the pore rate is increased. The backing space provides more absorption and makes the peak frequency down to low.

Aggravation of natural environment, improvements in income, internet diffusion, spread of five-day work a week, and population aging seem very different from each other. However they boil down to consumption. These culture patterns are changing into environment-friendly and productive housing culture. In other words, people might tend to have frequent contacts with not only environment-friendly housing in bustling cities but also woods that is environment friendly materials in their leisure time. In the period of people young and old alike are in favor of woodcrafts, this study was conducted for giving information to who speicalized in woodcrafts. Furthermore, the study shows that other countries also added grain and figure to woodcrafts for visually appealing.

BACKGROUND: White stain symptom caused by Acremonium acutatum and Trichothecium roseum, is one of the most important diseases on the grape. This disease occurs national-wide in Korea and causes irreversible damage on grape, at harvest season. This study was conducted to develop environment-friendly control method against white stain symptom. METHODS AND RESULTS: Environment-friendly materials were tested for control activity against A. acutatum and T. roseum in vitro and in vivo. The effect of environment-friendly materials against white stain symptom on grape in farmer's greenhouse was examined. The materials, NaDCC and sulphur, were sprayed three times on the leaves and fruit of grape at the two sites of farmer's field, Anseong and Hwaseong of Gyeounggi. To evaluate control effect of NaDCC and sulphur against white stain symptom, the disease severity was investigated after the two materials were sprayed from the disease onset three times at the 7-day intervals. NaDCC showed efficacy of 59.71% for Kyoho and 72.26% for Campbell-Early, and sulphur showed 78.31% for Koyho and 66.19% for Campbell-Early. CONCLUSION: We were selected sulphur and Sodium-Dichloroisocyannurate(NaDCC) based on the results of experiments in vitro. In field test, sulphur and NaDCC showed suppressive effect in the white stain symptom of grape. These results suggested that NaDCC and sulphur selected can be used as control agents for controlling white stain symptom on grape.

Inhibition effects on spore germination and mycelia growth for gray mold (Botrytis cinerea) were investigated in vitro using environment-friendly agricultural materials as well as environment-friendly pesticides. The inhibition effect on mycelia growth of gray mold is the highest when the gray mold mycelia were treated with a pesticide (commercial name: Koreayeok, Jihabudea KM, Sootingtan, Sootingstar) that contains a mixture of Bacillus subtilis, resulting in 100% inhibition of the mycelia growth. Meanwhile, the range of less than 20% inhibition effects on the growth of gray mold mycelia was observed with other commercial agricultural materials. The significant inhibition effects on spore germination of gray mold fungus were shown in vitro with two water dispersible pesticides containing sulfur [BTB (97.7%) and SulfurStar (92.3%)], respectively. These in vitro results of inhibiting of the spore germination and mycelia growth together cannot found. It remains to be determined whether the selected environment-friendly agricultural materials in effective control of gray mold in vitro can be used to control gray mold in field.

This study was conducted to investigate the differences in households, parental perception, and dietary behaviors of preschool children from kindergartens with environment-friendly food service (environment-friendly food service group; EFG) versus children from kindergartens with general food service (general food service group; GFG). We sought this basic information to examine the impact of environment-friendly agricultural products in preschool food services. Age, education level, and monthly family income of the EFG were significantly higher than the GFG. The frequency of purchasing environment-friendly agricultural products was significantly higher in the EFG than the GFG, with the most frequently purchased items in both groups being vegetables. The GFG had a significantly higher perception than the EFG in the superior quality of environment-friendly agricultural products; however, a greater proportion of the GFG than the EFG thought environment-friendly products were too expensive. The most frequent reason for purchasing environment-friendly agricultural products in both groups was safety. When purchasing environment-friendly agricultural products, the most important selection factor for the majority of both groups was the label certifying quality assurance. Both groups also considered price reduction as essential for promoting environment-friendly agricultural products. In regard to parental perceptions on food service in kindergarten, the EFG had a significantly higher satisfaction with the nutritional adequacy of the menu compared to the GFG. Both groups considered food safety and health as primary reasons for using environment-friendly foods in the preschool food service, with a greater proportion of the EFG than the GFG responding this way. There were significant differences between the EFG and GFG, as the main satisfaction from using environment-friendly foods in the EFG was safety, freshness, and good hygiene, whereas the main satisfaction in the GFG was a good food service menu, freshness and good hygiene. Dietary behaviors of preschool children in the EFG were also significantly superior to the GFG. Thus, environment-friendly agricultural products have positive effects on the dietary behaviors of preschool children and should be increased in the preschool food service. Lowering prices and a strict supervision of quality assurance is also necessary to promote consumption of environment-friendly food materials.

With the recent increasing interest in sustainability management, the latest environmental report tends to be substituted by the expanded sustainability management report. In this work, I would like to introduce the management pattern of a global enterprise that values environmental soundness (environmental friendly) and implements eco-friendly measures. The enterprise chosen in this study is FedEx. In this article, FedEx case is presented how companies can adopt environmental friendly management in their businesses. FedEx has maintained an eco-friendly management since the introduction of the company's eco-friendly transport trucks in 2003, following its development in 2000. In 2005, it installed a solar power plant that can supply up to 80% of the electricity consumed by Oakland Logistics Center in California, USA. FedEx has published the "Global Enterprise Citizenship Report," which contains its business developments in 2009. FedEx has worked hard to minimize the influence caused by packaging of goods to the environment and appealed to customers to use recycled products as much as they can. FedEx also encourages customers to use packaging materials efficiently. A considerable amount of energy has been expended in the eco-friendly programs of FedEx. Although thousands of FedEx vehicles and aircraft operate daily with using large amounts of electricity and fuel, FedEx focuses on energy savings and global environment protection.
