  • Nanotechnology is the fastest growing area in scientific research and it has important applications in a wide variety of fields. Nevertheless, consumers encountered this new technology without any identification of risks and benefits. Also until now, there are no specific safety evaluation methods for nanotechnology. For this reason, we studied risk communication strategy for nanotechnology to prepare its application in commercialized products on public. A survey was conducted to identify the differences in perception between public (N=110) and expert (N=37) toward applied nanotechnology in food, drugs and cosmetic products. The survey results were used to draw up a risk cognitive map which was introduced by Paul Slovic, and the perception level of public and expert on nanotechnology was evaluated. As a result of the survey, public recognized nanotechnology as "unknown but low dread" risk factor, but expert recognized it as "unknown and high dread" risk factor. These results indicate that there are perception differences between two groups. Several risk communication strategies are reported including care, consensus and risk communication. In the case of nanotechnology, it contains both risks and benefits. Considering the nature of nanotechnology, the "consensus communication" which informs consumers about risks and benefits of issues is the most appropriate strategy.

  • Increasing knowledge on the link between diet and human health has generated a lot of interest in the development of functional foods. However, several challenges, including discovering of beneficial compounds, establishing optimal intake levels, and developing adequate food delivering matrix and product formulations, need to be addressed. A number of new processes and materials derived from nanotechnology have the potential to provide new solutions in many of these fronts. Nanotechnology is concerned with the manipulation of materials at the atomic and molecular scales to create structures that are less than 100 nm in size in one dimension. By carefully choosing the molecular components, it seems possible to design particles with different surface properties. Several food-based nanodelivery vehicles, such as protein-polysaccharide coacervates, multiple emulsions, liposomes and cochleates have been developed on a laboratory scale, but there have been very limited applications in real food systems. There are also public concerns about potential negative effects of nanotechnology-based delivery systems on human health. This paper provides an overview of the new opportunities and challenges for nanotechnology-based systems in future functional food development.

  • The purpose of this research is to understand the general consumer knowledge and adoption intention of nanotechnology products, one of the advanced scientific fields. We examined consumers' knowledge of innovation products based on nanotechnology, by gender and age group, which are divided into benefits, cost, and trust perception. As a result, the benefits were highly perceived in the order of perceived usefulness, perceived gains, and perceived ease of use. In general, it was found that men and older age group perceived the benefits of nanotechnology to be relatively higher than women and younger age groups did. In terms of cost, perceived risk was relatively higher than other variables and a high innovation resistance appeared in the younger 30s group. Finally, we found that trust for nano-related institution is relatively lower than trust for nano-related people and trust for nanotechnology itself.

  • Nanotechnology is a rapidly expanding field, focused on the creation of functional materials, devices, and systems through the control of matter on the nanometer scale. Recently many countries including Korea are rushing into promoting research and development of nanotechnology. Because the nanoscale is not just other step toward miniaturization, but a qualitatively new scale, progress in nanotechnology will have very far-reaching social, ethical, and environmental impacts. This paper aims to examine social issues and implications of nanotechnology development. To do so, this paper divides the issues around nanotechnology into several sub-issues: environmental, health-related, and societal issues. And then this paper reviews the debates and disputes around those sub-issues. Based on this review, this paper proposes some policy recommendation.

  • In this study, high school students' perceptions and attitudes toward nanotechnology are examined through questionnaires gathered from 1704 high school students (five general high schools and two science high schools). As a result, the study shows that high school students have generally high perceptions and positive attitudes toward nanotechnology. Science high school students show more positive attitudes and correct knowledge toward nanotechnology rather than general high school students do. High school students get information on nanotechnology via various sources such as TV and internet, whereas they have rarely perceived to get information on nanotechnology in textbooks and science class. They think that newspaper and TV programs are proper methods to introduce new science technology and get information on the advanced science and technology through the internet and science teachers. High school students show positive attitudes toward the application of nanotechnology, whereas they show negative attitudes toward personal information chips and nano-taste enhancer. And they trust nanotechnology researchers and science teachers, whereas they rarely trust about government, public organizations, and internet.
