Purpose - Environment-friendly behaviors are diverse and can be motivated by different factors. For example, magnitude of factors affecting recycling behavior could be different from those affecting purchasing of environmentally-friendly products. In this study, the focus is on usage satisfaction of consumers who have purchased environmentally-friendly products. Research design, data, and methodology - For this purpose, data were collected from a total of 345 users of environmentally-friendly products, consisting of 177 users of electric vehicles and 168 users of environmentally-friendly detergents. The study analyzed the relationships among consumer's innovation propensity, consumer's environmental concern, and usage satisfaction. In addition, the moderating effect of the product's innovativeness was examined. Results - The result shows that there is a relationship between consumer's innovation propensity and consumer's environmental concern. In particular, it is shown that both consumer's innovation propensity and consumer's environmental concern have positive effects on usage satisfaction. Further, there was a moderating effect of the product's innovativeness. Namely, products rated higher in innovativeness showed a greater effect of consumer's innovation propensity on usage satisfaction. The degree of the product's innovativeness also affected the directional paths of the relationships. In the electric vehicle (i.e., high product innovativeness) case, consumer's innovation propensity had a direct effect on usage satisfaction, as well as an indirect effect through consumer's environmental concern. In the environmentally-friendly detergent (i.e., low product innovativeness) case, consumer's innovation propensity only had an indirect effect on usage satisfaction, through consumer's environmental concern. Conclusions - Theoretical contributions of this study are as follows. Foremost, this is the first study that suggests an existence of a relationship between consumer's innovation propensity and consumer's environmental concern. Second, this study showed the positive effect of consumer's innovation propensity on usage satisfaction of environmentally-friendly products. Third, this study expanded the scope of previous studies by showing the interaction between consumer's innovation propensity and consumer's environmental concern. Lastly, this study showed that the effect of these variables on usage satisfaction can differ by the degree of innovativeness of the environmentally-friendly product. The results of the study will have implications for marketers and policy makers in formulating marketing activities and policies.

This study investigates the factors that induce the early adoption of environmentally friendly vehicles. We measure the affective, cognitive, and behavioral factors influencing the early adoption intentions of car owners in three countries (the US, Germany, and Japan). We find that affective and cognitive factors are significant, but behavioral factors are only partially significant. Specifically, eco-centric values and knowledge about green technology are significant in explaining early adoption intent. However, of the behavioral factors, usage context is significant, whereas commute distance is not significant in explaining early adoption intent. Finally, between-country differences indicate that any policy to increase the adoption of environmentally friendly vehicles should be fine-tuned for each country.

The recent trend of vehicle design aims at crash safety and environmentally-friendly aspect. For the crash safety aspect, energy absorbing members should be absorbed with collision energy sufficiently. But vehicle structure must be light weight for the environmentally-friendly aspect, in order to improve fuel efficiency and to reduce tail gas emission. Therefore, the light weight of vehicle must be achieved in a status of securing safety of crash. An aluminum or CFRP (Carbon Fiber Reinforced Plastics) is representative one among the light-weight materials. In this study, impact collapse behavior of circular hybrid thin-walled member is evaluated. The hybrid members are manufactured by wrapping CFRP prepreg sheets outside the aluminum circular members in the autoclave. Because the CFRP is an anisotropic material whose mechanical properties change with its stacking condition, special attention is given to the effects of the stacking condition on the collapse behavior evaluation of the hybrid thin-walled member. Collapse mode and energy absorption capability of the hybrid thin-walled member are analyzed with change of the fiber orientation angle and interface number.

Various efforts of reducing the green house gas in the whole industrial fields including railway industry have been implemented. Tilting train is the key example because it can run more faster on the existing rail than others due to its composite body. The system has an advantage of light weight but also a task to solve, recycling of composite material. To recycle the CFRP(Carbon Fiber Reinforced Plastic), there are two typical methods; chemical and thermal method. In this study, more environmentally friendly recycling method was recommended through the environmental function through comparing both recycling methods.

Starting with the development of environmentally friendly electric controlled engine, sensors have played an increasing role in automotive technology. Electric power steering (EPS) systems are more and more replacing hydraulic systems. To improve fuel economy, the power assistance is provided by an electric drive. In this paper, development of a unique torque sensor for EPS is introduced. A capacitive type torque sensor is concluded to be suitable for EPS because its output is accurate, linear and robust against the variance of temperature, and patents have not applied so much.
