As environmental problems such as global warming, and ecocide have a great influence on society, the attention to environmental pollution is being expanded. To solve the environmental problems, the awareness and practice of members of society in question is required. However, it has been found that few people are participating in practising environmental protection in real life. Our main goals are to show that Gamification has great potential in delivering messages for public interest and to suggest guidelines for researchers and public contents developers who engage in designing in relation to Gamification. Based on the domestic and foreign theoretical investigations, we found that Gamification mechanism made based on psychological mechanism of users aims at public interests' value by maximizing motivations of users and spreading social relationships among people. As shown in the case study, if contents are developed by reflecting the elements which stimulate challenging of users, the elements which can express their opinions, and the elements of altruism which form the sympathy in the development of public interest contents in the future, practical participation of people to solve social problems can be expected.

The purpose of this study was to investigate the use and perception of adults concerning bokbunja (Rubus coreanus Miquel) products. Self-administered questionnaires were collected from 502 residents in the Daegu and Gyeongbuk area. According to the survey more females in their 20s responded than males (45.2 and 54.8%, respectively). In total, 82.6% of respondents had an income of under 4,000,000 won per month and most were living in the city. The results regarding knowledge about bokbunja products showed that the bokbunja wine score was highest (3.66), and intake frequency showed that over half of the respondents had never eaten bokbunja products. The preference for bokbunja wine by males was higher than that for females, whereas the others products showed higher scores for females than for males. When asked about how they knew about bokbunja products, 37.0% of males and 46.9% of females responded a family member or neighbor. When purchasing bokbunja products, males and females answered that they considered taste, country of origin, and manufacturer, and price. Approximately 48% of the respondents answered that they purchased bokbunja products in the grocery and department store.
