This research intends to help local small fashion industry to outgrow its limitation, preserving and developing environment-friendly dyeing tradition in Jeju renowned for persimmon juice dyeing. The study, then, aims to develop eco-friendly golf-wear designs, with maximizing advantages of natural dyeing (with persimmon juice, indigo plant, gallnut, cochineal, turmeric, and loess) such as rot-proofness, bacteria-proofness, stench-proofness and block of ultraviolet rays. The results are as follows: first, natural fabrics such as muslin(cotton 100%), linen(linen 100%) and spandex(mixed cotton 98%, polyurethane 2%) were developed into eco-friendly ones colored with various natural dye sources. Second, four kinds of golf-wear design were developed to stand out golf wear's natural image, focused on classic, neo-minimal style. The characteristic details and design elements of sportswear were added to basic golf wear design. Therefore, it is hopeful that those designs of naturally dyed golf wear for women could be utilized for other various purposes in the future.

In order to improve wear and fatigue resistance of the structural materials, especially cold work roller for 304 stainless steel, an eco-super-finishing and surface hardening treatment using ultrasonic vibration energy was developed and applied to the SKD-ll roller. The eco-super-finishing machine was designed and fabricated by DesignMecha Co, by its own technology. It was observed that the surface roughness, hardness and residual stress were changed from $Ra{\;}={\;}O.25\mu\textrm{m}$, Hv=710 and ${\sigma}$={\;}+400{\;}MPa{\;}to{\;}Ra{\;}={\;}0.165\mu\textrm{m}$, Hv = 1200 and ${\sigma}=-610$ MPa after 20 KHz micro-cold forging, which means almost equal to the 300 % improvement of life-time.

As environmental issues have become a worldwide concern after the 20th century, the idea and the term of 'green growth development' has become familiar to the public. After 2008, the green growth development dramatically became an important ideology in Korea; thus industries, studies and product investments in relation are in active progress. Following the trend, the latter major unit of the middle school textbook "Technology & Home Economics" was named the revision of elementary, middle and high school textbooks in 2009. The learning goal of 'green' or 'eco-friendly' of the revised edition of the textbook will guide the middle school students to have better understanding of the issues of clothing habits and the environment. Furthermore, students will be able to apply the 'green' concepts in their real life and put eco-friendly clothing habits into action. Thus, the practice of effective learning will depend on the quality of the current issue of the textbook. Therefore this study analyzes the eco-friendly contents of the semi-unit from 7 different textbooks and presents an example of textbook production to the preliminary teacher of home economics.

Purpose: This study proposed a systematic approach to measure eco-efficiency of products based on the concept of quality function deployment(QFD). QFD method has been used to convert customer's subjective requirements to design specifications. A extension of QFD to environmental issues is known as quality environmental function deployment(QEFD). QEFD includes environmental requirements into customer's demand for quality, and incorporates them to design specifications of a product. Methods: In this study, we compared eco-efficiency of old and new models through application of QEFD. Results: The result revealed that the new model's eco-efficiency improved 24% better than the old model. Also, we found that user's Factor X of the new model has been improved to 1.178, which is about 18% better than that of the old model. Conclusion: This study implied that we can systematically use QEFD to determine eco-efficiency of two comparable products in any industries.

This study measured consumer's recognition, reliability, emotion and images about current eco-marks as well proposed an eco-mark rating scale and mark designs to improve consumer's trust on the fashion product marks. We used a questionnaire survey to collect data from 150 persons about knowledge, interests, and practice on eco fashion products in relation to trustfulness and positive images for three domestic and three international eco-marks. We evaluated and gave eco scores to six fiber-type products (cotton, organic cotton, wool, polyester, biodegradable polyester and nylon) in terms of consumer's use, water & land consumption, waste amount, carbon footprint, and toxicity. We suggested a new 5-level rating scale for eco marks, which quantified the concept of environmental friendliness of fiber products. The design for eco-mark of rating scale showed the total grade with two sub scores of environmental sides and human sides developed with an improved visual understanding for consumers. The design is one through benchmarking the energy-consumption efficiency mark, which is familiar to consumers such as a half circle shape to save environment resources to alarm consumers to environment problems.

Most of eco-friendly agrifood processing enterprises in Korean rural area are small and medium-sized business. For this reason, it's hard for eco-friendly agrifood processing enterprises to neither analyze business performance for efficient business management nor establish their own business plan for rational decision-making. Therefore it's necessary to design effective mathematical programming model and to make practical application which can support rational management decision-making ensuring the stable business activity of eco-friendly agrifood processing enterprises. Accordingly this paper focuses on the designing and its application of multi-objective mathematical programming model using goal programming to support rational decision-making of eco-friendly agrifood processing enterprise. Hansalimanseongmachum Food Inc. which runs soy bean processing business making tofu based on regional-based soybean farms around Anseong City will be the specific case to apply multi-objective mathematical programming model in practice. And it will suggest measures to support rational management decision-making of other eco-friendly agrifood processing enterprises.

Purpose - This paper discusses the effectiveness of EcoFarmer in Zimbabwe. The effectiveness of EcoFarmer still needs to be established because it is a new product that is hardly a month old. Research design, data, and methodology - The paper follows a qualitative research methodology and an exploratory approach to establish the effectiveness of EcoFarmer in the promotion of productivity in the agricultural sector in Zimbabwe. Using an Internet-based literature review, the paper explored the link that exists between Econet's EcoFarmer program and agricultural development in Zimbabwe. Results - The findings are that the innovation promotes agricultural productivity. This is in line with what was established by Safaricom Foundation in Kenya. Conclusions - The paper used literature sources because the phenomenon is exploratory. This limitation could have been avoided by using a field survey. The paper shows that the EcoFarmer is an innovative project that was developed by Econet as a replication of the Kenyan program.
