Lately, the scale of the primary energy consumption in Korea is ranked 10th in the world, and it takes up about 1.9% of the entire energy consumption in the world. And among total energy consumption in Korea, the ratio of the part corresponding to the residence or commercial buildings is about 30.5%. Also, with the increased interest in eco-friendly buildings, the production of eco-friendly building materials consisting of them also increases as well. However, since the process of their production generates much energy consumption, so this is being raised as a social problem. Therefore, this study suggests a method to improve thermal performance by using eco-friendly earth plastering materials and natural materials in order to reduce energy consumption in buildings. The experiment evaluated thermal performance by measuring the external and internal temperature of the curing after the plastering of 1cm in the wooden box of 30cm * 30cm * 30cm. As a result, there was difference in the order of powdered coal, pealite, chaff, and rice straw. Among them, powdered coal indicated excellent thermal performance. This will be the foundational research used to improve interior environment and reduce heating bills.

The environment and green are critical issues for businesses in the $21^{st}$ century. This study examines product assortments of eco-friendly products, green marketing strategies, and the marketability of Trashion products among fashion brands. Data were collected through an interview method from eight fashion brands that were actively conducting green marketing. The general activities of green marketing were to produce eco-friendly products and/or an economical support for environmental groups or green conservation campaigns. Eco-friendly products included organic cotton products, well-being products made of bamboo or beans, goods made of recycled plastic bottles, and Trashion items. The first reason was to improve the brand image, then take social responsibility, and last participate in the environmental movement. However, the price of green products and supplies of eco-friendly fabrics were the most challenging issues for fashion businesses. The marketability of Trashion products was directly opposed and managerial implications for green marketers were discussed.

Root-dipping inoculation method has been widely used to determine the resistance of watermelon to Fusarium oxysporum f. sp. niveum causing Fusarium wilt. Although this method leads to the precise results of plant disease responses, more rapid and efficient assay methods have been still required because the root-dipping inoculation method is labor-intensive and time-consuming. In this study, we established a simple and effective bioassay method based on the comparison of various inoculation methods and growth conditions. To develop the system, the occurrence of Fusarium wilt on four resistant and susceptible cultivars was investigated by four different inoculation methods, root-dipping, scalpel, tip and soil-drenching methods. Of these inoculation methods, scalpel method resulted in clear plant disease resistance responses with the simplicity. With the use of scalpel method, we also explored the disease development of the cultivars depending on inoculum concentration, growth stage of seedlings, and incubation temperature after inoculation. Furthermore, we found that the resistance degrees of 23 cultivars derived by scalpel inoculation method were similar to the results by root-dipping method established previously.

Root-dipping inoculation method has been used to investigate resistance of radish plants to Fusarium wilt. However, the method requires a lot of labor and time because of complicate procedure. This study was conducted to establish a simple and effective mass-screening method for resistant radish to Fusarium wilt. Radish seedlings of susceptible and resistant cultivars were used to investigate wounding method by scalpel, inoculum concentration, and pathogen-inoculated growth stage of seedlings. We established an efficient mass-screening method based on our results as following: Roots of 14-day-old seedlings of radish are cut with a scalpel at a $90^{\circ}$ angle to a 2 cm-depth at a 1 cm-distance from main stem and then inoculated by pouring with a 10 ml-aliquot of a fungal spore suspension ($1.0{\times}10^7conidia/ml$) on soil. The inoculated plants are cultivated in a growth room at $25^{\circ}C$ for about 4 weeks with 12-hour light a day. The proposed screening method enables to effectively select resistant from mass radish plants cultivars to Fusarium wilt.

This study was conducted to select and develop effect of eco-friendly organic materials for the eco-friendly prevention of Anthracnose occurred in the ginseng. Anthracnose on ginseng is occurred by Colletotrichum gloeosporioides and the crop damage is severe especially from July to August after rainy season. The test results showed that control effect by test products materials on the three years ginseng and four years ginseng field was lower in eco-friendly organic materials than that of chemical pesticide. However, the control effect of bordeaux mixture was higher with 71.3% and 73.8% levels than those of mineral matter, microbial agent, and developed plants extract mixtures (Eugenol, Curcumin, Wood vinegar, etc). On the other hand, three types of developed plants extract mixtures (3 types) showed control effect in a range of from 58.1% to 63.6% against Anthracnose which was higher as compared with plant extract alone and sodium silicate regardless of ages of ginseng. The results of this study would attribute in verifying the control effect of eco-friendly materials against Anthracnose for ginseng through investigating antimicrobial compounds contained in the plants body. Also, it would be used as control method against Anthracnose occurred in ginseng by judging the right control time through monitoring occurrence of disease.
