A survey was conducted to investigate the relationship between knowledge of perceived food safety and actual food purchase practices among parents of children under the age of seven (N=309) in 2005. The seventeen following perceived food safety items were included in the survey (bovine spongiform encephalopathy, foot and mouth disease, pathogenic avian influenza, swine fever, allergens, GMO, irradiated food, food poisoning bacteria, endocrine disrupter, antibiotics, food additives, carcinogen, natural toxin, agrichemical residues, place of origin, cultivation methods, and heavy metal) Most parents were highly concerned about investigating all food safety topics. Up to 90.0% of the participants recognized the importance of food safety. The public concern has caused a considerable decline in the demand for food afterreceiving news about food safety through mass media, Also, the majority of subjects required correct food safety information.

This study was carried out to develop of macro-protocol and the biosafety guide Golden Rice, modified vitamin A at large scale GMO field. Commercialization of genetically modified (GM) plants will be required the assessment of risks associated with the release of GM plants that should include a detailed risk assessment of their impacts in the environment and human health. Prior to GM plant release, applicants should provide the information on GM crops for approval. A total of $4,700m^2$ GM field, each of Golden Rice and 'Nakdong' were used for further analysis on agronomic traits and pathogenesis. Generally plant growth and panicle number in the transgenic lines were lower than in the wild type under field condition. The major agronomic traits such as plant growth, grain quality in Golden Rice were similar than in 'Nakdong'. The yield difference was due to reduced ripened rate and the 1,000 grain weight. The grain shape was similar donor plant, however, color of brown rice was different from segregation. Also the difference of pathogenesis reaction was not significant in the leaf blast and sheath blight between Golden Rice and 'Nakdong'. These results provided the agronomic data and pathogenesis for risk assessment analysis of Golden Rice and suggested that the macro-protocol could be useful to detect GM plants.

The SPS Agreement, concluded in the Uruguay Round for the purpose of controlling SPS risks, has traditionally been recognized to maintain the narrowest scope of application compared with TBT Agreement and GATT in relation with environmental provisions. Contrary to such an understanding on the scope of the SPS Agreement, the panel in the EC-Biotech case found that the SPS Agreement extends to regulate trade-restrictive measures on Genetically Modified Organizations(GMOs) causing health and environmental risks. This expanding scope of the SPS Agreement would have substantial influence on domestic environmental regulations as well as Multilateral Environmental Agreements(MEAs). This paper discusses the consequences of an expanding ambit for the WTO SPS Agreement through the designation of a wider range of health and environmental regulations affecting trade as SPS measures. As a result, not only precautionary measures on GMO risks, but also other health and environmental measures with trade impacts, could be subject to SPS control, and consequently, the institutional rigors of the WTO regime. However, strict and literal interpretation of the SPS provisions to expand its applicable scope would cause concerns about the WTO's intervention on the purely environmental measures. Pursuing harmonized and flexible interpretation of provisions on environment-related conflicts as well as accepting precautionary principle included MEAs will contribute to reduce such kind of concerns.

DNA watermarking have been interested for both the security of private genetic information or huge DNA storage information and the copyright protection of GMO. Multimedia watermarking has been mainly designed on the basis of frequency domain, such as DCT, DWT, FMT, and so on, for the robustness and invisibility. But a frequency domain watermarking for coding DNA sequence has a considerable constraint for embedding the watermark because transform and inverse transform must be performed without completely changing the amino acid sequence. This paper presents a coding sequence watermarking on lifting based DWT domain and brings up the availability of frequency domain watermarking for DNA sequence. From experimental results, we verified that the proposed scheme has the robustness to until a combination of 10% point mutations, 5% insertion and deletion mutations and also the amino preservation and the security.

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.

A survey of consumers' awareness and attitudes about genetically modified food and korean labelling regulation entered into force in July, 2001 was conducted from October, 2001 to January 2002. The questionnaires were distributed to 519 consumers who are members of panel survey system of Korea Consumer Protection Board and lived in 7 largest cities of Korea. The consumers were asked about knowledge, concerns of potential hazards, intention of purchasing, and present labelling regulation. More than 85.7% of the respondents had some knowledge on genetically modified (GM) foods. More than 44.9% of consumers relied on the information from the civil activity group but only 9.6% of consumers from the government. The greatest benefit of GM food was thought to be a solution for the food shortage in the future. While, regarding a potential hazard, more than 71.6% of respondents worried about the safety of GM foods. First of all, 52.2% of korean consumer concerned about food toxicity or side effect. 53.2% of consumers responded that they would not purchase GM labelled foods and about 28.0% of respondents suspended judgement on willingness to purchase until they would get more information. Regarding complement field of present GMO labelling regulation, over 45.2% of consumers responded that labelling was needed to be more easily found. Also more than 95.1% of consumers hope to expand a list of mandatory labelling articles.

As increasing trade through the world, especially in food, asymmetry of information can make the trade shrink. With the industrial development, Korea's agriculture had shrunk dramatically. By the result of the nation's industrial restructuring, over than 3/4 of Korea food consumption comes from abroad. And China is an important source of agricultural product to Korea. Increasing family income and increasing importing food consumption, Korean consumers have been interested in food safety. Especially. after experiencing several cases like struggle for safety of GMO food, poultry influenza, lead contained Chinese fish import, mad cow disease, cheating origin, etc. Obviously, those unreliable cases will hinder the increase of world free trade as well as the trust of two countries. Furthermore, distrust will be a cause of adverse selection. So, it need to find a way to solve the distrust which caused by asymmetry of information. And automatic identification procedures can help mitigate asymmetry of information in trade. And it will make Korean consumers can avoid adverse selection. This paper suggests adoption of Auto ID to encourage agricultural trade between Korea and China.

This study was carried out to develop of macro-protocol and the biosafety guide for 'Nakdong', and 'Golden Rice' (genetically modified vitamin A rice) by large scale field trial of GM crops. Typically, when a new GM crop is created, breeders should conduct field test to make sure the GM crop is safe, and provide some information on GM crops for approval. A total of isolated 4,700 $m^2$ field for trial of GM crops were prepared, and 'Nakdong' and 'Golden rice' were cultivated by standard method of RDA (Rural Development Administration, Korea). Field studies indicated that the population densities of insect pests and natural enemies have no difference between two varieties. While insect pest density on 'Nakdong' was slightly higher than on Golden Rice, but natural enemy density on Golden Rice was a little higher. These results provided the insect diversity for risk assessment analysis of Golden Rice and suggested that the macro-protocol could be useful to detect GM plants.

Asian Branches of International Life Science Institute (ILSI), i.e. China, India, Japan, Korea and South East Asian Region, identified five key public health issue priorities of each region and compared the results. In case of China, India and South East Asian countries (Indonesia, Malaysia, Philippines, Thailand etc. ASEAN countries), communicable diseases were the first priority issue, while elderly issue and food safety were prime issues for Japan and Korea, respectively. Malnutrition was the second priority issue for India and ASEAN countries, whereas non-communicable disease like cancer and degenerative diseases was for Korea and China, and obesity far Japan. Typical issues were smoking for China, nutrition education for China and Japan, biotechnology aiming GMO for India, and functional food causing health claim problem for Korea and Japan. Although the priority varied with the socioeconomic situation of each county, food and water safety recorded the highest priority of all the countries. The key public health issues of Korea were discussed in detail.

The ontology alignment has two kinds of major problems. First, the features used for ontology alignment are usually defined by experts, but it is highly possible for some critical features to be excluded from the feature set. Second, the semantic and the structural similarities are usually computed independently, and then they are combined in an ad-hoc way where the weights are determined heuristically. This paper proposes the modified parse tree kernel (MPTK) for ontology alignment. In order to compute the similarity between entities in the ontologies, a tree is adopted as a representation of an ontology. After transforming an ontology into a set of trees, their similarity is computed using MPTK without explicit enumeration of features. In computing the similarity between trees, the approximate string matching is adopted to naturally reflect not only the structural information but also the semantic information. According to a series of experiments with a standard data set, the kernel method outperforms other structural similarities such as GMO. In addition, the proposed method shows the state-of-the-art performance in the ontology alignment.
