This study aimed to investigate the effect of environmental education programs using action learning on elementary school students' environmental literacy and self-efficacy. To this end, an environmental education program using action learning was applied to 22 sixth graders of 'A' Elementary School in Busan. The results of this study were as follows. First, environmental education programs using action learning were effective in improving the environmental literacy of elementary school students. After implementing the environmental education program using action learning, students' environmental values, cognitive, and procedural ability changed positively. Environmental issues awareness and ecological knowledge improved, and there was a significant increase in environmental behavior and environmental function. Second, environmental education programs using action learning were effective in enhancing the self-efficacy of elementary school students. After implementing environmental education programs using action learning, students' confidence in problem solving and their ability to judge their behaviors improved. Third, elementary school students showed active participation and interest when conducting environmental education programs using action learning. Students have become open to protecting the environment when they find problems, devise solutions, and practice them. After reflection, it was confirmed that students' immersion and satisfaction in class were high as a solution was reached, leading to efforts to sell items they did not use and donate profits to environmental protection organizations.

This study was conducted for the purpose of suggesting ways to improve KMLA's support programs to strengthen the capabilities of domestic medical librarians. To this end, after investigating the roles of professional associations, common roles were extracted and categorized into five areas, and then the support programs of MLA and KMLA were compared and analyzed. As a result, six suggestions can be made as ways to improve KMLA's support program. First, policy development is needed to officially and continuously support medical librarians. Second, in the area of (continued) education and training programs, educational support in professional areas required in the medical field is needed, as well as education for the role of the IRB committee. Third, in terms of research and publication support, various support for research funds and training programs is required. Fourth, in terms of network and cooperation support, mentoring, leadership, and fellowship programs are needed, and improvements to domestic and international partnerships and support for various awards should also be planned. Fifth, in terms of professional certification and various certificate systems, it is necessary to provide support for obtaining degrees in related fields and to issue certificates through support for various courses. Sixth, KMLA's active internal and external promotion and activities should be carried out to attract donations.

While electricity demand is generally increasing, stably controlling supply is becoming a serious challenge because renewable energies are becoming popular and often their productions are dependent on the weather. The 'demand response' programs can be used to complement the problems of renewable energies, and therefore their role is becoming increasingly important. This study provides an analysis of a demand response pilot that was conducted in Korea. The study first focused on questionnaire surveys and in-depth interviews, and the data was used to perform a Technology Acceptance Model (TAM) analysis. The goal of the pilot was to have the residential users reduce their power consumptions when an energy reduction mission is issued during peak load hours. The experimental subjects consisted of two groups with different characteristics. Subjects in group A obtained smart meters as an optional function of IoT platform service provided by a mobile service company, and received a charge deduction as their compensation. Subjects in group B either voluntarily purchased smart meters as individuals or received them by participating in an energy self-sufficient village program that was run by a local government, and were entitled to a donation as their compensation. With the analysis, group A was found to fit the extended technology acceptance model that includes perceived playfulness in addition to perceived ease of use and perceived usefulness. On the contrary, group B failed to fit the model well, but perceived usefulness was found to be relatively more important compared to group A. The results indicate that the residential energy groups' behavior changes are dependent on each group's characteristics, and group-specific DR design should be considered to improve the effectiveness of DR.

Eco-tourism has been recognized as a form of sustainable development that simultaneously satisfies the need for environmental preservation and the activation of local economies. Although some research findings relating to its positive environmental and social effects have been published, there is still controversy regarding its pros and cons in terms of its actual economic benefits, and little research about how they can be increased. Thus, the following research analyzes how the tour activities, attitudes and satisfaction of 314 actual visitors was related with their consumption behaviors, by surveying tourists to Suncheon Bay, a highly popular destination with a large number of visitors. The results are as follows. First, if the tourists were involved in a link-up tour, had prior eco-tourism experience, or had researched information on SunCheon bay eco-tourism before their visit, these were all positively correlated with consumption behaviors, and increased the amount of money they spent. In particular, among tour spending activities, accommodation cost is shown to be highly correlated with tour activities. Second, Free Independent Tourist(FIT) tended to show more positive tour attitudes than package tourists, spending more on accommodation and experience programs. The visitors to SunCheon Bay showed strong environmental attitudes, followed by social and cultural attitudes, and economic attitudes, in that order, and tourists with positive attitudes had a high rate of participation in experience programs. In addition, program participants showed a willingness to donate, and high satisfaction. Therefore, the following thesis proposes that Free Independent Tourist(FIT) should be induced to increase their contribution to the local eco-tourism economy, and highlights the need to develop various experience programs, aggressive advertisements and educational activities.
