This research categorizes fundamental data needed to develop eco-friendly fabrics treated with bamboo leaf & pine leaf extracts. The effect of mordant on those fabrics was analyzed through the measurement of mechanical properties and the estimation of primary hand values for cotton and silk fabrics dyed with bamboo leaf and pine leaf extracts that were later treated with various mordants. When cotton was dyed with bamboo leaves and pine leaves extracts, EM, WT, 2HB, 2HG, 2HG5, LC, T, and W increased however, RT, SMD, and RC decreased compared to raw cotton fabric. The B, G, and MIU increased after mordant treatment to the dyed cotton and resulted in a stiffer and rougher cotton's hand. EM, WT, RT, MIU, WC, T, and W increased (in terms of silk); however, LT, B, 2HB, G, 2HG, 2HG5, MMD, SMD, and LC decreased compared to raw silk fabric. Similar to the dyed cotton, mordant treatment increased the MIU and LC of dyed silk subsequently, the hand became stiffer and rougher. A greater tannin adsorption results in an increased mechanical property and the primary hand value. For both fabrics, mordant treatment made its smoothness drop. However, the scale of drop for cotton was significant, while the scale of the drop for silk was minor. In terms of type of mordant, femordant and natural-mordant treatment influenced the tensile, shear, surface properties of fabrics, and primary hand values more than Cu-mordant and synthetic-mordant in addition, this increased the stiffness, hardness, and roughness of fabrics.

This study analyzes the relation of the consumption values and ethical fashion consumption behavior as well as other influential factors between Korean and German ethical consumers based on the 'Modified Theory of Planned Behavior.' A survey was conducted on female consumers in their 20s and 30s, who experienced ethical fashion consumption in Seoul and Berlin. A factor analysis, reliability analysis, F -test and multiple regression analysis were performed for model verification. The research results indicated that emotional value (in case of Korea) and functional value out of consumption values (in case of Germany) have significant effects in regards to the influence of consumption values on ethical self-identity. The effects of ethical self-identity on ethical fashion consumption behavior indicated that Korean ethical self-identity influenced the ethical fashion consumption behavior of moderating and simplicity and eco-friendly certification versus local consumption as well as above factors (in case of Germany) explained by ethical self-identity. Both variables had a negative moderating effect in Korea in regards to the moderating effects of social comparison and materialism in the relations of ethical self-identity and ethical fashion consumption behavior; however, only materialism was an influential factor in Germany. The results of the research variables by individualism/collectivism indicated that the horizontal-collectivism group showed the highest ethical self-identity along with the lowest materialism tendency that had a high point of consumption behavior towards local consumption. However, the vertical-individualism group was outstanding. The consumption behavior aimed at moderating and simplicity.

This study was conducted to compare annual productivity of whole crop rice and winter crops in paddy field of southern region in Korean peninsular. Whole crop rice (WCR) varieties used in this experiment were Suwon 605, Yeongwoo, and Mogwoo bred at the National Institute of Crop Science (NICS), and Rye (Gogwoo), Italian ryegrass(IRG, Greenfarm) and Triticale (Choseong) were used as winter crops. Each crop was cultivated using the standard cultivation method and harvesting of whole rice was carried out about 30 days after heading date. The dry matter (DM) content was the lowest in Italian ryegrass (p<0.05), and the highest value was 29.4% in triticale. The dry matter yield of rye was the highest (p<0.05), and there was no significant difference between Italian ryegrass and triticale (p>0.05). There was no difference in forage quality among seeding time of each species, but there was a difference among the species (p<0.05). In particular, rye showed lower CP, IVDMD, TDN and RFV values than other species. The average dry matter production of whole crop rice was 18,484 kg/ha, but there was no significant difference among the cultivars (p>0.05). Crude protein (CP) content was significantly lower in Mogwoo than other and TDN and RFV values were the highest in Mogwoo. In the annual productivity evaluation, combination of rye-Suwon 605 showed the highest DM yield at 26,515kg/ha. Based on the above results, it was concluded that the combination of Suwon 605-rye (Gogwoo) was the most effective cropping system for annual forage production using whole crop rice and winter crop in the southern region of Korean peninsular.

In this project a preliminary experimental research work was done to apply mortars containing magnetite as fine aggregates unto floor finishing materials in order to make indoor environment eco-friendly and to have noiseproof control between floors. Crushed magnetites were substituted as sands in the mix design with a range of 0, 20, 40, 60, 100%. First far-infrared radiation tests to determine emissivity and emission power were done in accordance with the KICM test standard and an outstanding result was obtained. Density and compressive strength test results also showed that as the substitution increases, test values increase in a linear trend. However dry shrinkage test results revealed that as the substitution increases, shrinkage strain also increases. To clearly seek a solution about this problem, more experimental works should be done on oncoming experimental program.

The purpose of this study was to propose the direction of veganism-based fashion design in environmental and animal protection through the theoretical consideration of vegan fashion and the analysis of the practical design characteristics of veganism in Stella McCartney's fashion. The research was conducted through literature research and case studies. After investigating the concept and characteristics of vegan fashion, focusing on previous studies and various fashion-related Internet data, Stella McCartney's fashion was examined with particular attention on vegan characteristics. The results of the study are as follows: First, imitative nature pursues animal and environmental protection, but the motif or appearance is a characteristic of pursuing a multi-purpose design that imitates animals and nature. Second, expression of value is based on slow fashion, simplicity, and sustainable minimal design. It is expressed indirectly by pursuing permanence, simplicity, and long-wearable design, or directly expressing vegan values through phrases expressed in performances or costumes in the collection. Third, alternative eco-friendliness is characterized by using cruelties-free materials such as faux fur, recycling materials, new bio-materials, and regenerated materials. These vegan characteristics are comprehensively and organically expressed in the works of the collection, and through this, sustainable and eco-friendly vegan fashion is pursued. It is anticipated that by deriving the vegan fashion characteristics of Stella McCartney, who represents vegan fashion, it will be possible to provide the basis for practical direction and design methods for fashion brands aiming for vegan fashion styles.

According to the government policy of environmental regulations, interest of ship, which made with High-Density Polyethylene (HDPE) as a low-carbon and eco-friendly material, is growing as a substitute for the existing fishery boat hull materials such as FRP, aluminum, steel etc. However, regulations related to the production of HDPE ship are still quite incomplete. Even there are no regulations related to structural analysis. Therefore, in this study, structural analysis is carried out by applying different design loads for each international classification for 38ft class HDPE power boats, and the results are compared and analyzed. According to this study, although there is a correlation between the based pressure value and the analysis result value of each class regulation, it is not necessarily proportional. Also, This analysis result shows a difference not only depending on the size of design load, but also application range of the load, the pressure adjustment factor and section shape. However, the occurrence point and trend of the maximum stress values were quite consistent. It is hoped that the results of this study will be used when establishing HDPE ship structure analysis procedures and standards in the future.

As the industry of 21C has been developed, the gas industry has grown and it has not only the convenience but also the riskiness fer using. Especially, the energy and environment problems have been getting serious after the modern industry revolution. Therefore, the demand of gas as an eco-friendly energy source is getting increased. With the demand of gas, the installation and use of gas boiler is also increased, so human life injury by the waste gas(CO) of boiler goes on increasing every year. Therefore, we want to find out the harm to human body through the study on the concentration of CO by the length of the curved exhaust tube of boiler. The allowable concentration of CO is 50ppm. The length of the one-meter-three-curved tube after three minutes is applicable to 50ppm of the threshold limit values of CO. Also, five meters exceed the threshold limit values of CO after five minutes. Strangely, the concentration of CO is under the threshold limit values from two to four meters.

With the development of IT convergence technology and the construction of master plan for the four rivers restoration of the government, the importance of the eco-friendly water pollution management is being spotlighted. In this paper, we proposed the effective water pollution management using the reservoir tank automatic classification for improving the water quality and on-line managing efforts of ceo-friendly reservoir tanks. The proposed method defined the seven factors of water pollution evaluation and managed the water pollution according to hydrogen ion concentration(pH), chemical oxygen demand(COD), suspend solid(SS), dissolved oxygen(DO), count of coliform group(MPN), total phosphorus(T-P), and total nitrogen(T-N) using the sensors. We measured the values for the seven factors from the reservoir tank and normalized to ranging from 1 to 9. To evaluate the performance of the water pollution management using the reservoir tank automatic classification, we conducted F-measure so as to verify usefulness. This evaluation found that the difference of satisfaction by the traditional system was statistically meaningful.

'Slow fashion' has become a hot issue in the fashion world as fast fashion has caused environmental and ethical problems. This study synthesized the characteristics of slow fashion from preceding studies and organized them into four characteristics (craftsmanship, nature-friendly attitude, localism, and pursuit of exclusive value). This study compared designers, John Alexander Skelton and Geoffrey B. Small with four characteristics. First, both designers sought craftsmanship based on tailoring, but Skelton focused on the eco-friendliness of materials, and Small emphasized the development of high-quality fabrics. Second, we found a nature-friendly attitude in both designers, but unlike Skelton, which maintains nature-friendliness in the process of clothing production, Small showed this characteristic through presentations. Third, both designers revealed localism through their affection for the fabrics and culture of each country. Moreover, Small extended its meaning to respect minority tastes. Finally, both designers pursued exclusive values through collections under the themes of class problem, and gender conflicts. However, Skelton melted these topics into British culture and revealed them indirectly versus Small who showed sensitive topics directly in the collections. This study will provide the foundation for analyzing designers through the characteristics of slow fashion, and suggests directions that slow fashion designers should move towards.
