Based upon the nucleotide sequence of As strain of cucumber mosaic virus (CMV-As0 RNA4, coat protein (CP) gene was selected for the design of oligonucleotide primers of polymerase chain reaction (PCR) for detection and identification of the virus. Reverse transcription and polymerase chain reaction (RT-PCR) was performed with a set of 18-mer CMV CP-specific primers to amplify a 671 bp fragment from crude nucleic acid extracts of virus-infected leaf tissues as well as purified viral RNAs. The minimum concentrations of template viral RNA and crude nucleic acids from infected tobacco tissue required to detect the virus were 1.0 fg and 1:65,536 (w/v), respectively. No PCR product was obtained when potato virus Y-VN RNA or extracts of healthy plants were used as templates in RT-PCR using the same primers. The RT-PCR detected CMV-Y strain as well as CMV-As strain. Restriction analysis of the two individual PCR amplified DNA fragments from CMV-As and CMV-Y strains showed distinct polymorphic patterns. PCR product from CMV-As has a single recognition site for EcoRI and EcoRV, respectively, and the product from CMV-Y has no site for EcoRI or EcoRV but only one site for HindIII. The RT-PCR was able to detect the virus in the tissues of infected pepper, tomato and Chinese cabbage plants.

The purpose of this study was to explore the levels of ethical consumptions and related variables on ethics of adolescents as consumers. This subjects were 552 middle and high school students. The research results are summarized as follows. 1. The scores to measure ethical consumptions level of the adolescents was ranged from 2.87 to 3.08, which were relatively low. 2. The ethical consumptions(fair-trade product consumption, donation and giving, local consumption and eco-friendly consumption) in demographic variables were found to have significant differences depending on their religion, perceived social class, father's education and mother's education. 3. The result of hierarchical regression analysis indicated that consumer education experience, the eco-friendly values, materialism, saving, experiencing mass media on affecting the fair-trade product consumption. The major variables affecting the ethical consumptions in the donation and giving were materialism, consumer education experience, experiencing mass media and the eco-friendly values. The significant variables affecting the local consumption were the eco-friendly values, consumer education experience, materialism, experiencing mass media and saving. The major variables affecting the eco-friendly consumption were the eco-friendly values materialism.

The purpose of this research to look into formative characteristics of eco T-shirt design. Previous study researchers have mostly focused on overall eco fashion design, but on the other hand the research on eco product entity leaves much to be desired. We analyzed formative characteristics of eco T-shirt design that is easily accessible in real life and is easy to passing message. We selected 23 eco brands through internet and analyzed total 500 photos of eco T-shirt. Each photo was categorized by sex and the nations which belong to the eco fashion world associations. The content and statistical analysis was used for data analysis. The content of the research is as the following. First, it was found out that basic straight silhouette, achromatic color, human pattern, plant pattern, and eco-friendly organic material were used for the design of eco T-shirt. Second, it showed difference of silhouette, color, pattern according to nations. Third, it showed difference of silhouette, color, pattern according to sex. Fourth, symbolism of eco T-shirt was nature love, nature support, society ethicality, anti-sociality, and economics. This research aims for providing practical help and assistance to the development of eco T-shirt and its relevant industries.

Excessive consumption, pollution, and am expanding global population are seen as very important issues that must be solved through reusable materials and the reduction of energy consumption. This study examines the values and design elements such as line, color, and textures in eco-friendly fashion that could contribute to the product development of an eco-friendly brand. The following methods of analysis were used in this study. An in-depth interview (where the interviewer records the response of interviewers to questions) was used to grasp the diverse design properties of products that customers need or want and the recorded interviews were documented by computer using open coding. The results show that the personal, economic, and social value of eco-friendly fashion has increased, in addition to the environmental value. The needs and preference of customers for eco-friendly fashion design were diversified and the consumer consciousness was more advanced than the consciousness of experts. This shows that it is not enough to consider the effect on the environment. In conclusion, understanding the personal, environmental, economic, and social value from the viewpoint of customers, finding the optimal design factors, and reflecting them in the development of products are necessary for advanced eco-friendly fashion.

Purpose: This study measured the consumer-perceived importance and satisfaction of eco-friendly food selection factors and performed the IPA to derive the factors that need to be maintained, reinforced, improved and selectively improved or where investment need to be minimized, and thus provide some clues for eco-friendly food companies' sales growth. Research design, data and methodology: To this end, efficient questionnaires of a total of 312 respondents who answered the questions about the importance of and the satisfaction with 20 selection attribute factors of eco-friendly foods were returned, and then, paired-samples t-test and IPA by all respondents, gender, age and incomes were conducted. Results: The analysis showed that a maintenance/reinforcement strategies planned by companies are required for some factors including 'safety' and 'product quality' at the first quadrant, while active improvement strategies are required for others including 'price' and 'flavor' at the second quadrant. Conclusions: The findings show that different marketing strategies should be established for each consumer who often purchase eco-friendly foods, and that more effective and efficient performance of eco-friendly food companies may be acquired by establishing and operating active improvement strategies.
