This study examined how the consumers' perception of GM food affects their purchasing behavior. In addition, this study investigated how the amount of knowledge a consumer has regarding GM food affects their perception of this type of food. The quantitative research method was used to collect data. The data from a self-administered survey, which was conducted in South Korea, was analyzed using descriptive analysis, ANOVA, factor analysis, and multiple regression analysis methods. The results of the survey indicate that most respondents may have unknowingly purchased GM food. Further, the respondents reported that they likely had known about or had heard of GM food. In addition, the survey indicated that the amount of knowledge possessed by the respondents regarding GM food greatly affected their perceptions of this type of food. These findings will contribute to the current GM food market by providing the food market with additional information relating to the consumers' perceptions of GM food.

Food labelling rules reflect the interaction of a number of factors such as industry needs for marketing flexibility and minimal regulations, consumer's rights to know what is in the product and public health concerns. However, food labelling rules could apply to international trade as non-tariff barriers so it is necessary to make multilateral harmonization of food labelling rules. For this, GATT XX, SPS, and TBT of the WTO can serve as jurisprudence in agreements. Lgnoring the safety problems of GM food, which is currently a worldwide issue, it is a situation that needs international harmonization of GM food labelling methods, harmonization of technical terms which are used in Korean law, and clear interpretation criteria for GM food labelling methods and contents are vital for sustainable trade in agricultural products. Therefore, this study proposes interpretation criteria through major trade countries' GM food labelling methods and an examination of Korean law. Furthermore, this study proposes international harmonization guidelines for GM food in the future.

The application of ganghwa mugwort (GM), ascorbic acid (AC), and their combinations for reduction of residual nitrite contents was analyzed in pork sausages during storage of 28 d. Six treatments of pork sausages contained the following: Control (no antioxidant added), AC (0.05% AC), GM 0.1 (0.1% GM), GM 0.2 (0.2% GM), AC+GM 0.1 (0.05% AC + 0.1% GM) and AC+GM 0.2 (0.05% AC + 0.2% GM). Results showed that the mixture of 0.05% AC and 0.2% GM was most effective for reducing thiobarbituric acid reactive substances (TBARS) and residual nitrite contents than the control and GM added sausages alone (p<0.05). The color values of all treatments were significantly affected by adding GM (either alone or with AC). Additionally, the total color difference (${\Delta}E$) and hue angle ($H^{\circ}$) values of treatments added with GM were higher than those of the control as the amount of GM increased (p<0.05). However, there were no significant differences in the pH values between the control and all treatments during the storage period (p>0.05). Our results showed possible applications of antioxidant combination, for preventing the lipid oxidation and decreasing the residual nitrite levels of meat products.

It was determined whether the sandwich ELISA using specific anti-CP4 EPSPS polyclonal and monoclonal antibodies, developed in the previous study, could be applied to detect GM soybean or not. The soybeans (47 imported and 20 domestic soybeans) were analyzed by a sandwich ELISA. The results of imported soybeans were divided into two groups which were high contents $(39.1{\pm}13.5\;{\mu}g/g,\;n=33)$ and low contents of CP4 EPSPS $(2.6{\pm}1.2\;{\mu}g/g,\;n=14)$. The ratio of GM in imported soybeans was about 70.2%. One the other hand, the contents of CP4 EPSPS in domestic soybeans was very low $(0.9{\pm}0.5\;{\mu}g/g,\;n=20)$ which determined to be non-GM soybeans. In case of soybean sprouts, the contents of CP4 EPSPS in soybean sprouts were different between GM and non-GM soybean sprout. The CP4 EPSPS in cotyledon of GM soybeans sprout was higher than that in root hair. The contents of CP4 EPSPS in soybeans sprout of domestic soybeans were very low. Thus, it was possible to determine that the soybeans sprout was made of GM or non-GM soybeans. Also, PCR experiment showed that the sandwich ELISA was accurate to distinguish the soybeans to be GM or non-GM. These results showed the sandwich ELISA could determine the soybeans were GM or non-GM, rapidly and simply.

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.

The changes of life-style by improving the standard of living produce the development of food service industry. But, the consequence is that food waste also increase. I think that the problems about the food waste become more critical. There are some reports about counting the amount of remaining foods until now. But, I can not find reports about the calory analysis of the remaining foods. So, I analysis the amounts and calories of the food and remaining food served at the restaurants for the purpose of groping how to reduce the remaining food and conclude as follows. First, the average amount of the food giving to one person is 1007gm(from 300gm to 1367gm), and the average amount of the remaining food is 126gm(from 29gm to 172gm). Second, the average calory of the food giving to one person is 795.5kcal(from 464kcal to 1225kcal), and the average calory of the remaining food is 140.8kcal(from 29kcal to 289kcal). So, we gain 130kcal more than recommending calory to woman. Therefore, we need to studies of developing menu, controlling the amount of supplied food, and improving how to supply. Also we need to study about the using of food bank and publish and use about recycling of food waste.

A survey of consumer awareness and attitudes was conducted about genetically modified (GM) foods and the labeling regulations. The questionnaires were distributed to 4,620 consumers who lived in a variety of areas in Korea, and 4,076 people responded. The consumers were asked about knowledge, labeling information, and the source of obtaining information about GM foods. More than 11.5% of the consumers had never heard about GM foods and 86.9% of consumers had less than a normal level of knowledge about GM foods. No statistically significant relationship was found between genders, but the teachers group had moderate knowledge (p<0.001). In total, 28.4% of consumers did not know the GMO labeling regulations. They answered that the reason to buy GM food was do not know>nothing wrong>create benefit>think as safe>inexpensive. The answers to the question of what was the first benefit were: solve food shortage>functional and nutritious food>cultivate in bad condition>nothing>various cultivars. They answered that the worst factor was the next generation effect>environmental disruption. Regarding the development of GM food in Korea, males answered do not know>stronglyrecommend>defer>strongly suppress. Female answered: don't know>defer>strongly recommend>strongly suppress. More than half of the respondents did not have much information about GM foods; 88.3% of respondents answered they did not have educational experience about GM food.

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.

This study was aimed to develop a novel qualitative multiplex polymerase chain reaction (PCR) for simultaneous detection of genetically modified (GM) soy and maize within a single reaction. The specific primers designed to detect four respective GM events (A2704-12, MON88017, Bt11, and MON863) were included in the tetraplex PCR system. Each of PCR products for four GM events could be distinguished by agarose gel based on their different lengths. The specificity and reproducibility of this multiplex PCR were evaluated. This multiplex PCR consistently amplified only a fragment corresponding to a specific inserted gene in each of the four GM events and also amplified all four of the PCR products in the simulated GM mixture. These results indicate that this multiplex PCR method could be an effective qualitative detection method for screening GM soy and maize in a single reaction.

A survey of consumers'awareness and attitudes about food biotechnology was conducted during May through August of 2001 with a random sample of 750 Korean consumers. More than 70% of the respondents was exposed to some informations related to genetically modified (GM) foods. The greatest benefit of the development of GM foods was thought to be the remedy for the food shortage in the future. More than 90% of Korean consumers wanted GM foods labeled. About 20% of the respondents would buy GM foods voluntarily, whereas over 50% would not until they found out more. More consumers responded that they would not buy herbicide-tolerant GM soybean but buy vitamin-enriched GM soybean. It seemed to be that many Korean consumers do not make decisions of acceptance or rejection of GM floods not on the basis of biotechnology but on the basis of the word(s) used to describe the products, such as herbicide and vitamin. Only 4% of Korean consumers responded that GM foods were the greatest safety-threatening factor of Korean foods and that the most interested information on food labels was whether the food was produced by biotechnology.
