  • This study analyzed the degree of demand for genetically modified organisms(GMOs) to provide the basic information for consumers' reasonable purchase decision making and their right to know about GMOs. Based on the (Ed-there are no study results above) study results, the following suggestion were made. First, throughout the survey, it was found that those consumers who participated had a high level of perception on the harm of GMOs. Therefore, reliable organizations such as government agencies are required to present the results of safety tests and formulate plans related to the safety of GMOs. Second, the average score on consumers' level of consumer knowledge on GMOs was very low, being 1.68 out of a possible 8 points. Third, since women and housewives engaged in dietary habits and food had high demand for information on GMOs, it is necessary to provide women with information on GMOs. Fourth, since it is difficult to confirm the presence or absence of GMOs. in rapidly increasing demand for fast-food, it is necessary that consumers be provided with relevant information and make a reasonable judgement in purchasing food. Fifth, it is necessary to provide detailed regulations and measures for concrete contents and directions of information on GMOs. Sixth, it is necessary to provid information on GMOs from the commercial sources of information that are most preferred by consumers.

  • The prospect of live vaccines consisting of genetically modified vaccinia virus expressing foreign genes is exciting, but important issues concerning safety and efficacy need to resolved. Vaccinia virus (VV) is an efficient expression vector with broad host range infectivity and large DNA capacity. This vector has been particularly useful for identifying target antigens for humoral and cell-mediated immunity. The WHO smallpox eradication program, involving the extensive use of VV vaccines, resulted in the late 1970s in the elimination of one of the world's most feared diseases. This achievement is a triumph for preventive medicine and for international collaboration in public health. In 1980, WHO recommended that the routine use of smallpox vaccine should be stopped. Against this background, the prospect of li ve vaccines consisting of genetically modified VV expressing foreign antigens arising from the work of Moss, and Paoletti and their colleagues in 1982 has been greeted with enthusiasm. These investigators have shown that genes coding for immunogenic proteins can be inserted into VV DNA without impairing the ability of the virus to grow in cell culture. Moreover experimental animals infected with VV recombinants containing genes coding for a variety of immunizing proteins have been shown to be protected against challenge infection with the corresponding infectious agent. In this communication, I describe current progress in the construction of a novel plasmid vector that facilitate the insertion and expression of foreign genes in VV as well as the selection of recombinants.

  • Two genetic constructs used to confer improved agronomic characteristics, namely herbicide tolerance (HT) in maize and soyabean and insect resistance (Bt) in maize, are considered in respect of feeding to farm livestock, animal performance and the nutritional value and safety of animal products. A review of nucleic acid (DNA) and protein digestion in farm livestock concludes that the frequency of intact transgenic DNA and proteins of GM and non-GM crops being absorbed is minimal/non existent, although there is some evidence of the presence of short fragments of rubisco DNA of non-GM soya in animal tissues. It has been established that feed processing (especially heat) prior to feeding causes significant disruption of plant DNA. Studies with ruminant and non-ruminant farm livestock offered GM feeds demonstrated that animal performance and product composition are unaffected and that there is no evidence of transgenic DNA or proteins of current GM in the products of animals consuming such feeds. On this evidence, current HT and Bt constructs represent no threat to the health of animals, or humans consuming the products of such animals. However as new GM constructs become available it will be necessary to subject these to rigorous evaluation.

  • 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.

  • Over the last five years, we have conducted research on risk assessment of domestically developed genetically modified (GM) crops and found a number of factors which could delay risk assessment process. In this review, we described such cases and discussed the problem of transgene cassette integration, the lack of information on vectors, the poor quality control in seed production and absence of bioinformatic analysis on amino acid sequence homology before GM crop development. To solve these problems, we have suggested the introduction of the screening system of elite event before risk assessment process and quality control strategies for GM seed production. In addition, we suggested that the developers of GM crops should understand the importance of risk assessment and management for the commercialization of those crops and consider the biological and ecological characteristics of host plants. Consistent communications may need to be established between GM crop developers, risk assessors and risk managers at the initial stages of GM crop development to reduce trial-and-errors.

  • The objectives of this study were to review various aspects of society on Genetically Modified Organism(GMO) in the view point of environmental sociology. There were many assertions related to GMO, and application of biotechnology. Some people assert GMO as harmful to human health, and some people as not harmful, however, there were no proven evidences to report. Through the literature review, this study intended; 1) to identify the present condition of GMO, 2) to weigh the pros against cons of views on GMO, 3) to study an aspect of society on GMO, and 4) to assert its necessity to mark GMO or not, because citizens have a rights to know natural or GMO. Based on the conclusions of this study, following recommendations were offered: 1) To review continually the GMO in the view point of environmental sociology especially in the areas of food safety, biosafety, trade, and public research investment, and 2) further detailed studies of GMO may necessary to ensure safety to human health and environment.

  • The goal of this study was to examine which factors influence consumers' demands to reveal the identity of GMO(Genetically Modified Organism) food, risk perception, and decision-making to purchase it. Consumers perceived its risk, and demanded labeling to identify it. Not many consumers wanted to buy GMO food. The results also revealed as follows. First, the level of demand to label for identifying GMO food were high among female consumers, consumers with negative attitude, and consumers severly perceived its risk. The level of perceived risk was high among consumers who were old and had high income, exercised their own healthy programs, showed negative attitude toward GMO food, and demanded strongly for labelling. Second, old consumers, consumers with high income, consumers concerning more about health, consumers with negative attitude and strong demand to label for identifying GMO food were more likely to perceive risk highly for GMO food. Third, consumers' attitudes and the level of perceived risks for GMO food significantly influenced the decision-making to purchase GMO food. However, other variables turned out not to affect consumers' decision-making to purchase it.

  • For the development of qualitative and quantitative PCR methods of genetically modified (GM) pepper developed in Korea, a capsanthin-capsorubin synthase (CCS) gene was used as the endogenous reference gene. The primer pair ccs-F/R amplifying the pepper endogenous gene gave rise to an amplicon of 102 bp. No amplified product was observed when DNA samples from 16 different plants were used as templates. The construct-specific primer pairs amplifying the junction region of the bar gene and Ti7 introduced in GM pepper gave rise to an amplicon of 182 bp. Quantitative PCR assay was performed using a TaqMan probe and a standard plasmid as a reference molecule, which contained both an endogenous and event-specific sequence. For the validation of this method, the test samples containing 0.1, 1, 3, 5, and 10% GM pepper were quantified.

  • The rhizobacterial composition varies according to the soil properties. To test if the effect of herbicides on the rhizobacterial communities of genetically modified NK603 glyphosate-tolerant maize varies according to different soil locations, a comparison was made between the effects of glyphosate (Roundup Plus), a post-emergence applied herbicide, and a pre-emergence applied herbicide (GTZ) versus untreated soil. The potential effect was monitored by direct amplification, cloning, and sequencing of the soil DNA encoding 16S rRNA, and high-throughput DNA pyrosequencing of the bacterial DNA coding for the 16S rRNA hypervariable V6 region. The results obtained using three different methods to analyze the herbicide effect on the rhizobacterial communities of genetically modified NK603 maize were comparable to those previously obtained when glyphosate-tolerant maize was grown in soil with different characteristics. Both herbicides decreased the bacterial diversity in the rhizosphere, with Actinobacteria being the taxonomic group most affected. The results suggest that both herbicides affected the structure of the maize rhizobacterial community, but glyphosate was environmentally less aggressive.

  • Genetically modified (GM) crops are not permitted to be cultivated in Korea, but can only be imported as food or feed purposes. The import of GM crops has sharply increased in recent years, thus raising concerns with regard to the unintentional escape of these crops during transport and manufacturing as well as the subsequent contamination of local, non-GM plants. Hence, monitoring of GM crops was studied in or outside of grain receiving ports as well as from feed-processing plants in Korea during July 2008. We observed spilled maize grains and established plants primarily in storage facilities that are exposed around the harbors and near transportation routes of the feed-processing areas. Based on the PCR analyses, a total of 17 GM maize plants and 11 seeds were found among the samples. In most cases, the established maize plants found in this study were at the vegetative stage and thus failed to reach the reproductive stage. This study concludes that, in order to prevent a genetic admixture in the local environment for GM crops or seeds, frequent monitoring work and proper action should be taken.
