We studied an activation plan for utilizing eco-friendly agricultural products from agricultural producers' perspective through delphi techniques. Certification types of eco-friendly agricultural products held by producers were low-pesticide 26.1%, no-pesticide 39.1% and organic 52.2%. The major problems in handling the eco-friendly agricultural products were as follows: 'consumer distrust', 'lack of reliable and continuous shipping quantity' and 'lack of storage facilities, such as cold storage'. The major benefits of direct transactions between producers of eco-friendly agricultural products and processed food manufacturers including HMR processing companies were 'obtaining fresh food ingredients for processing' and 'confidence-building and income stabilization'. Regarding requirements for cooperation of eco-friendly agricultural producers and processed food manufacturers including HMR processing companies, the most common answers was 'multi-year contract based on trust'. When asked about governmental support for efficient cooperation between eco-friendly agricultural producers and processed food manufacturers including HMR processing companies, the most common answer was 'supporting plan for small producers' and 'arrangement for appropriate potential consumers'.

We studied the basic properties and fabrication of reduced graphene oxide (rGO) prepared using eco-friendly reduction agents in the graphene solution process. Hydrazine is generally used to reduce graphene oxide (GO), which results in polluting emissions as well as fixed nitrogen functional groups on different defects in the graphene sheets. To replace hydrazine, we developed eco-friendly reduction agents with similar or better reducing properties, and selected of them for further analysis. In this study, GO layers were produced from graphite flakes using a modified Hummer's method, and rGO layers were reduced using hydrazine hydrate, L-ascorbic acid, and gluconic acid. We measured the particle sizes and the dispersion stabilities in the rGO dispersed solvents for the three agents and analyzed the structural, electrical, and optical properties of the rGO films. The results showed that the degree of reduction was in the order L-ascorbic acid ${\geq}$ hydrazine > glucose. GO reduced using L-ascorbic acid had a sheet resistance of $121k{\Omega}/sq$, while that reduced using gluconic acid showed worse electrical properties than the other two reduction agents. Therefore, L-ascorbic acid is the most suitable eco-friendly reduction agent that can be substituted for hydrazine.

The purpose of this study was to examine consumers' perceptions of eco-friendly children's-wear and their impact on the selection criteria for children's-wear and stores. A descriptive survey method using a self-administered questionnaire was employed. The sample consisted of mothers with children under the age of 13 residing in Seoul and the Gyeonggi area. Data were collected from September 2011 to October, 2011. The collected data were analyzed to find the differences between purchasers and non-purchasers of eco-friendly children's-wear in terms of their perceptions of eco-friendly children's-wear, as well as the influence of these perceptions on the consideration degree of criteria for the selection of children's wear and store. The results indicate that perceptions of eco-friendly children's-wear implied five key factors related to quality reliability, expected value, style, degree of recognition, and dissatisfaction with design and price. The results also revealed some differences between the group purchasing eco-friendly children's-wear and the group not purchasing eco-friendly children's-wear. These different perceptions were related to the aspects of quality reliability, expected value, style, degree of recognition. In general, the non-purchasing group displayed a lower mean score than the purchasing group. Both groups showed a low interest in aesthetic appreciation and the degree of recognition factor. The results showed that consumer's perceptions of eco-friendly children's-wear had an influence on the criteria for the selection of children's-wear and store type in both groups. Considering the findings of the study, it is clear that both purchasers and non-purchasers of eco-friendly children's-wear showed differences in their perceptions and purchasing behavior. Therefore, marketing strategies to appeal to the non-purchasing group should be differentiated from strategies used to ensure the loyalty of the purchasing group.

We developed eco-friendly lightweight concrete in order to apply eco-friendly lightweight concrete into structural wall or slab of shallow depth urban railway system. However, since lightweight aggregate has different structural feature of porous and it has been overvalued at current KS standard when applied, we did compare the characteristics of freezing and thawing of normal weight aggregate concrete by comparative test method(KS, ASTM). According to test method, there was a big difference of dynamic elastic modulus in lightweight concrete rather than in normal weight aggregate concrete. The big absorption factor in lightweight aggregate is main reason for that. For more detail, in KS law in which only 14 days water curing is carried out, the big amount of moisture in lightweight aggregate is frozen and high heaving pressure occurs and finally that lead to destruction of lightweight concrete. Therefore, it is considered that in case of lightweight concrete, resistibility against freezing and thawing has been undervalued in domestic KS law compared to ASTM law, which is overseas standard. So, a variety of examination about testing criteria and rule would be necessary for exact assessment of lightweight concrete.

Purpose - The purpose of this research is to identify how idiocentric consumers and allocentric consumers respond to retail store environments and how such responses affect their consumer behaviors in a sustainable consumption setting. Method - Data were collected from 422 U.S. adult consumers via a web-based survey. Two store settings were created, perceptually related (eco-friendly clothing displayed with greenery)or perceptually-unrelated (eco-friendly clothing displayed without greenery), and consumers were asked to take the survey based on the given store setting. Results - Allocentric consumers perceived a product and its display environment were related whereas idiocentric consumers perceived the two were unrelated. Also, the former exhibited higher purchase intentions when the product and store environment were related (eco-friendly clothing displayed with greenery), but the latter did when the two were unrelated (eco-friendly clothing displayed without greenery). Conclusions - This research suggests that retailers should consider consumer self-concept at personal-level when implementing marketing strategies. This research also demonstrates that consumers are influenced by store environment in relation to their self-concept and that self-concept can be temporarily modified by various stimuli such as visual displays.
