This study conducted to examine the effects of a GMO education(n=108 university students). Although the experience of encountering GMO was 84.3%, awareness was moderate or lower for 76.9%, 62% were unaware of GMO labeling, and 44.4% had no previous education on GMO. After the education, GMO positive perceptions, specifically in terms of improving work efficiency(p<0.05), negative perception(p<0.001), and GMO knowledge increased significantly(p<0.05). The need for expanding GMO labeling (p<0.05) and adjust to 0.9%(exclusion criteria) for labeling(p<0.001) increased significantly. Moreover, there was a significant increase in the need and willingness to accept a price increase for the full labeling system(p<0.01), with a significant increase in the willingness to pay up to 20%(p<0.05). The pre-contemplation stage showed a significant decrease(p<0.001). The preparation and behavior and maintenance stage showed a significant increase(p<0.001). Based on these findings, it is suggested that GMO education be implemented to provide accurate information and emphasize the necessity of consumers' right to know and choose through the implementation of the full labeling system of GM foods.

This study was conducted to find out the factors affecting the stages of behavioral change about GMO(n=202 university students). 52.0% of the respondents had no experience in GMO education, the stages of pre-contemplation and contemplation were 35.6% and 29.7%, respectively. Experience and awareness on GMO were the highest at 86.6% and 51.5%, respectively, and 55% of the respondents did not know about the implementation of the labeling system. Positive and negative perceptions on GMO score were 3.41 and 3.22, respectively. The need for the full labeling system of GM foods was 56.4%, the intention not to pay when the price rises due to the system was 70.8%. Regression analysis of factors affecting the stages of behavioral change showed health interest(t=2.10, p<0.05), educational experience(t=2.81, p<0.01), knowledge score(t=2.260, p<0.05), and negative perception(t=2.13, p<0.05). The results of this study suggest that in order to increase the stage of behavioral change in GMO, it is necessary to raise interest in health and knowledge and have the correct perception through GMO education

Purpose: The objective of this study was to determine the effects of genetically modified (GM) food promotion and education through the blog. Methods: Education program for consumer-oriented GM foods by the blog was developed and survey was performed by the visitors for totals of twelve weeks. The blog was formed by information (definition, mark etc.) offering style and named as "Correct knowing of genetically modified organisms (GMO)." Event was held to enhance the promotion of the blog from the week 9 to week 12. Results: Visitors of the final week increased 4 times, as compared to those of the starting the event week 9. Most of the 138 consumers (94.5%) did not have prior GMO education experience. The 97 consumers aged 20 years old showed significantly the highest ratios in the experience of blog or website (p<0.01). Comparing before and after the blog education, notification on GM foods and willingness to buy GMO products, the benefit of GMO, willingness to check GMO mark when buying GMO products showed positive change of GM foods (p<0.05). Conclusion: Over 80% answered that the blog helped to understand the GM foods. Thus, we conclude using blog is effective way of GM food promotion and education and continuous efforts are needed to maintain an active blog for the consumer's rights of knowledge about GM foods.

This study was analyzed to provide fundamental data of food safety education way on the recognition, knowledge and purchase attitude of GMO foods. Data was collected from 270 University students in the Gyeong-gi region through a self-administered questionnaire. According to the results of the reliability and factor analysis, the knowledge and purchase attitude of GMO foods showed 0.742 and 0.832 in Cronbach alpha coefficient, 0.791 and 0.831 in KMO. There were significant differences in the recognition and intake possibility and purchase will, safety and absorption to a GMO foods between the specialty person and non-specialist (p<0.05). By the kind of GMO foods it appeared highly by the order corn (70.0%), tomato (67.5%), beans (63.3%) and potato (51.3%). There were significant differences in the general knowledge of GMO foods (p<0.05), whereas no significant differences in question 'There were no genes in ordinary beans' by a presence of a specialty (p>0.05). After the purchase attitude difference to the GMO foods was analyzed by a presence of a specialty, I appeared most highly in the question to which I say 'I think a GMO foods is ethical.' by a negative question and 'I think a GMO foods is mass-produced, and it's possible to make a food problem decrease.' by an affirmative question. Therefore, the purchase attitude of GMO foods showed a significant differences of University students according to their major (p<0.05). Based on this study, it is considered that provision of detailed and continuous education must be accomplished by raising the recognition of GMO foods and its acceptance level, allowing a proper understanding of GMO foods to be conveyed and assisting subjects from receiving the information they desire effectively by various education mediums.

This study was pursued to examine the differences in housewives' willingness of buying genetically modified(GM) Food by the basic knowledge and recognition toward GMO. The results could provide a basic information for the consumer education and consumer policy about genetically modified food. The final 723 observations collected using a questionnaire were analysed by frequency, percentage. mean, standard deviation, t-test.$X^2$. ANOVA. and duncan-test using the SPSS/WIN 10.0 programs. The main results were following (1) Consumers' basic knowledge about GMO was too low to understand or interpretate information regarding GM food which was provided or would be provided. So consumers education for very basic biology should be offered for consumer to understand and interpretate various information about GM food is provided. (2) Consumers didn't trust GM food information provided by government. however they wanted government to provide information regarding GM food. (3) The more basic biology knowledge consumer has, the better recognition of GM food and the higher possibility that they eat consumer has.

The goal of today's environmental education is to enhance the understanding of the serious of environmental problems and the interactions among environment. With this perspectives people need to be aware that environmental education is no longer a liberal arts in university education, but play a vital role within the socio-cultural context. This study was performed to assess the changes in the university student's attitudes and consciousness in real life after the education of a point at issues of environmental problems. For this study 11 questionnaires which were composed of large scale environmental problems(water and air pollution), and small scale environmental problems(food additives, GMO, endocrine disrupter) were performed with self-administered by university students(n=781) who made a application for liberal arts related to environmental subjects. According to the analysis the most student's consciousness of a point at issue of environmental problems(water pollution, air pollution, additives, GMO, endocrine disrupter), and practical attitudes(i.e., practical attendant at congregation and internet voting) were change statistically significant(p<0.01) after the education of a point at issue of environmental problems rather than before. Specially, the score for the item of the large scale problem of environmental issues(water pollution, air pollution) were decreased significantly(p<0.01), but the score for the small scale problems, such as food additives, GMO, endocrine disrupter were increased significantly(p<0.01) after the education of a point at issue of environmental problems(p<0.01). And among the students that participated, 97.7% responded that such a point at issues of environmental problem is needed at the university. With this educational improvements supports the states that the education of a point at issue of environmental problems were more essential, practical and needed to students at university rather than that of an existing instruction. Thus, further studies are required to develop the education of environmental issues at universities like STSE programme.

This study analyzed consumers' willingness to pay for price increases to avoid the purchase of GM foods by the expansion of GMO labeling. The subjects were asked about their knowledge of GM, concerns of potential hazards, and sources of obtained GM information. The logit model was employed and marginal effects were calculated to interpret the results. The results showed that consumers who perceived the safety of GM technology were less likely to pay for price increases, while consumers who had concerns about GM foods were more likely to pay. In addition, the study demonstrated that consumers residing in urban areas and with low levels of education and income were also less likely to pay for price increases.

The objective of this study was monitoring of genetically modified soybean by PCR and ELISA. We collected 60 soybean samples from the open markets located in Western Gyeongnam (Sacheon, Hamyang, Hadong, Sanchung, Uiryung, Geochang, and Hapcheon). A total of 60 soybeans was examined and 14 genetical modified soybean (GMS) were detected by PCR. The GMS rate of selling soybean in Uiryung, Hadong, Sacheon, and Hapcheon was 50.0%, 37.5%, 33.3% and 25%, respectively. The 7 of 14 GMSs were positive by ELISA and most of positive samples were below 3% GMS but 1 (Uiryung 1) of the positive samples was over the 3% which is maximum permit limit in Korea. These results mean that merchants of open market did not express for selling soybean mixed with GMS, so consumers did not recognize GMO. Therefore, we thought that education of GMO for merchant of open market need to recognize about GMO maximum permit limit.

The release of genetically modified organisms ($GMO_{s}$) into the environment has the potential risks regarding the possibility of gene transfer from $GMO_{s}$ to natural organisms and this needs to be evaluated. This study was conducted to monitor the possible horizontal gene transfer from herbicide-resistant zoysiagrass (Zoysia japonica Steud.) to indigenous microorganisms. We have first examined the effect of field-released GM zoysiagrass on the microbial flora in the gut of locust (Locusts mlgratoria). The microbial flora was analyzed through determining the 165 rDHA sequences of microorganisms. The comparison of the microbial flora in the gut of locusts that were captured at the field of GM zoysiagrass and of wild-type revealed that there is no noticeable difference between these two groups. This result indicates that the GM zoysiagrass does not have negative impact on microbial flora in the gut of locust. We then investigated whether the horizontal gene transfer occurred from GM zoysiagrass to microbes in soil, rhizosphere and faecal pellets from locusts by utilizing molecular tools such as Southern hybridization and polymerase chain reaction (PCR). When the total DNAs isolated from microbes in GM zoysiagrass and in wild-type zoysiagrass fields were hybridized with probes for bar or hpt gene, no hybridization signal was detected from both field isolates, while the probes were hybridized with DNA from the positive control. Absence of these genes in the FNAs of soil microorganisms as well as microbes in the gut of locust was further confirmed by PCR. Taken together, our data showed that horizontal gene transfer did not occur in this system. These results further indicate that frequencies of transfer of engineered plant DNA to bacteria are likely to be negligible.
