Purpose - This study examines the effect of consumers' motivations on the perception and purchase intentions of electric cars. Specifically, it empirically analyzes how moral motivations based on personal environmental values and norms in car usage and purchasing influence the perceived usefulness and purchase intentions of electric cars. Furthermore, it investigates whether the influence of moral motivations on perceived usefulness and purchase intentions varies according to the user's driving characteristics. Design/methodology/approach - An online survey was conducted with 234 respondents, by setting criteria for participants as car owners or primary car users within their households, ensuring the sample composition was not biased in terms of the presence or absence of experience with eco-friendly cars. Findings - The research findings indicate that perceived usefulness mediates the effect of consumers' moral motivations on their intention to purchase electric cars. The results of the moderating effect of driving distance on perceived usefulness revealed a significant interaction effect; however, there was no significant interaction effect on purchase intentions. Specifically, for individuals with shorter driving distances, as consumers' moral motivations increase, their perception of the usefulness of electric cars also increases. In contrast, for those with longer driving distances, the increase in perceived usefulness due to moral motivations shows a decreasing trend. Research implications or Originality - This study considered individual driving characteristics that previous research on electric vehicle adoption overlooked, and suggested that setting specific communicating points for electric cars according to driving distance levels might be effective. Lastly, it proposes directions for future research that motivations influencing eco-friendly vehicle purchases may differ based on driving characteristics

Advances in food packaging play an important role in keeping food manufacturing and food supply safe. Food packaging facilitates the storage, handling, transportation and preservation of food, and also contributes to the minimization of food waste. On the other hand, food packaging materials have high production volumes, short usage times, and accelerate the occurrence of environmental problems related to waste. The circular economy has already been introduced to pursue sustainability through resource conservation and recycling, and to reduce waste and carbon emissions. By activating an eco-friendly economic system that minimizes resource depletion and environmental pollution, reducing, reusing, recycling and redesigning the goals of the circular economy will reduce the impact of food packaging on the environment. This review focused on the safety aspects of recycled food packaging as recycling is currently considered an important means of packaging waste management. Assessing the safety of recycled packaging is very important because recycling can increase the levels of potentially hazardous chemicals in packaging and in the food after they are migrated. Various food packaging materials such as plastic, paper and cardboard, aluminum, steel, and multi-material multi-layers packaging are commonly used, but only the recycling safety of plastic food packaging materials, which is the most used and has a significant increase in post-use problem, is discussed in this review.

As abnormal climatic event occur frequently due to global warming, many nations have proclaimed their commitment to achieving carbon neutrality and are actively pursuing a transition toward a hydrogen economy. At this time, ammonia has garnered significant attention not only as a high-capacity hydrogen carrier but also as a promising candidate as a carbon-free fuel. In particular, anion exchange membrane fuel cells offer the advantage of directly supplying ammonia to the fuel cell, eliminating the necessity for separate ammonia decomposition or hydrogen purification. Therefore, in this study, the operation principle and research trend of the anion exchange membrane fuel cell are reviewed, and several research using ammonia as a fuel in anion exchange membrane fuel cell are also investigated.

More people have become interested in hybrid vehicles - which have been heralded as environmentally friendly automobiles - recently as the opening of domestic hybrid vehicle market draws near. Since gasoline, diesel and LPG hybrid vehicles will be produced, a need exists to conduct economic feasibility study of each vehicle type. This research analyzed projected benefits of these hybrid vehicles based on the 1600cc model. There are two categories of benefits: 1) reduced fuel costs for the owners of the vehicles; and 2) reduced environmental pollution cost. We conducted a sensitivity analysis and estimated the domestic consumer fuel costs based on the international oil prices of 100USD, 150USD, and 200USD per barrel. The analysis showed savings of 2 to 4 million Won in fuel cost and 1 to 2 million Won in environmental pollution cost; therefore, the hybrid vehicles are not economically feasible if they are between 3 to 5 million Won more expensive than the conventional internal combustion engine vehicles.

The purpose of this study is to examine the actual condition of environment conscious logistic system which is essential to make material recycling economic society. Environment conscious logistic management which meant simply recycle is tend to promote material reduction, reuse and recycling. We have made case studies about advanced environment friendly logistic system. To examine Korean companies' environment conscious logistic system, we made survey form which is consist of 82 questionnaires and 154 companies have participated for this. And we have analyzed the survey responses. As a result of this study, we propose the way of constructing environment conscious logistic system in Korea.

This study intends to review the sustainable agriculture and rural development concepts and practices and to present their directions toward better rural planning. Review of related literature including use of available documents and field visits both in Korea and overseas countries are two main methods of data collection with no quantitative analysis. Before sustainable (rural) development was fashionably used in the 1990s in the world, sustainable agriculture and other similar terminologies such as organic farming, alternative agriculture, low-input sustainable agriculture, natural farming, and environment-friendly farming are considered important in the academics as well as In action. The significant relationship between farmers' engagement in sustainable farming and their participation in voluntary social organizations is evidenced, so that it might be said that sustainable agriculture be the basis of sustainable rural development. Whether in sustainable agriculture or in sustainable rural development, the sustainable rural economy is considered more important toward better rural planning both in Korea and in the world.

We handed out questionaires to some high school students in order to find out the Environmental Consciousness, Knowledge, Values, and Attitudes of young people in Korea. The difference in such things of high school students between Korea and Australia was analyzed by comparison with aech other. It is revealed that the Environmental Knowledge of high school students in Korea is valued significantly high degree in most cases from this study. It is, however, not due to their Environment-Friendly Attitudes and besides the Environmental Terms are hardly understood to most of them. The Environmental concerns of young people in Korea and their view on the importance of Environment, which are not in accordance with those of young people in Australia on most issues, must have been mainly affected by differences in society, economy, education, and cultural background between the two countries.

The purpose of this study was to examine the relations between family functioning and the interpersonal relation disposition of high school students in southern Gyeonggi province. The subjects of this study were 360 high school students. The scale of family functioning was measured using the Family Adaptability Cohesion Evaluation Scale(FACES Ⅲ) developed by Olson, et al.(1985). To measure the interpersonal relation disposition, Ahn's Interpersonal Relation Disposition Scale(IRDS) was used. The data was analyzed by using t-test, ANOVA, and multiple comparison(Duncan test). The major findings were as follows: There were significant differences in student's family functioning and interpersonal relation disposition according to school department and family economy level. There were significant differences in the interpersonal relation disposition according to gender. Where family functioning was higher, the students' interpersonal relation dispositions were more sympathetic, accepting and socially friendly, while being less rebellious and distrustful. As a result of this study, it is found that family functioning has effects on high school students' interpersonal relation disposition.
