  • This paper is aim to report the core aspects of Codex guideline for organically grown food which is finalized by FAO/WHO Codex Alimentarius Commission on May 2000 in 28th session of the Codex committee on food labelling. The chapter of animal production had discussed for a long time before it was finalized in Ottawa/canada as well as use of GMO(Genetically modified organism), manure from factory farming, animal welfare, and fodder inputs consisting of at least 85% for ruminants and 80% for non-ruminants. As the guideline for Codex set out the several things which is very difficult for Asian country, Organic farmer in Korea should pay an attention to maintain/increase the fertility and biological activity by cultivation of legumes, green manures or deep-rooting plants in an appropriate multi-annual rotation programme, and incorporation in the soil of organic material from holding producing in accordance with the guidelines. Pest, diseases and weeds should be controlled by choice of appropriate varieties, appropriate rotation, mechanical cultivation, diversified ecosystems, flame weeding, animal weeding and steam sterilization. The use of plant growth hormone, GMO and manure from industrial management system are not allowed, and closed recycling system, rotation, resistant seeds again pest and disease should be practiced in organic farming. But these are not unfortunately practiced in the country. In the conclusion it was strongly suggested to enact the Basic Standard for Korean organic agriculture which contains the core principles of Codex guidelines, and to try the importation of the most advanced theory, skills and technology from leading country in organic farming.

  • Higher agricultural commodity prices are a particular concern for food importing countries like Korea that has a very low self-sufficiency ratio. Korean people eat approximately 4.5 million metric tons of rice each year, which is met without a problem by domestic production. The domestic production of corn and soybean which are important raw materials for commercial food processing and livestock feed is only minimal. Demands of corn and soybean in Korea are approximately 7.2 million and 1.3 million metric tons per year, respectively. Since Korean consumers are reluctant to accept biotech (GM) foods, Korean food processors are fighting an up-hill battle in purchasing non-biotech (non- GM) crops which are becoming scarce.

  • 유전자변형 벼 및 비변형 벼 재배시 근권미생물의 특성 및 군집변동상을 조사하였다. 유전자변형 벼 재배 및 비변형 벼 재배 근권토양 및 뿌리표면인 근면의 세균수는 큰 차이가 없었다. 수원지역 2006년도 포장시험에서 근권토양의 세균은 유전자변형 벼의 경우 Afipia가 12.5%, Spingomonas 10.0%, Ramlibacter 10.0%, Mycobacterium 7.5%, Tetrasphaera 7.5%였으며, 유전자비 변형 벼는 Afipia가 7.3%, Spingomonas 12.2%, Ramlibacter 7.3%, Mycobacterium 17.1%, Tetrasphaera 속이 14.6%로 우점하였다. 예산 시험포장에서 재배한 벼 뿌리표면의 우점세균은 2007년도에는 유전자 변형 벼 시험포에서 Arthrobacter 속 12.7% 유전자비 변형 벼 시험포에서는 Burkholderia 속 22.2%였으며, 2008년도에는 유전자변형 벼 시험포에서 Paucimonas 속이 26.6%, 비변형 벼 시험포에서는 Chryseobacterium 속이 15.4 %를 점유하였다. PLFA에 의한 미생물 군집은 유전자변형 벼 재배 유무에 따른 조건에서는 뚜렷한 경향이 없었지만 토양 간에는 다른 특성을 보였다.

  • 각 국은 소비자의 알 권리와 선택권을 보장하기 위해 식품표시제도를 의무화한다. 그리고 이러한 각국의 식품표시정책을 수립함에 있어 국제협약 또는 협정에 가입되었다면 이는 모든 서명국에 부과되는 의무라는 복잡한 네트워크에 연결된다. 또한 식품표시제도는 국제무역에 비관세장벽으로 적용할 수 있어 각 국이 식품표시제도를 도입함에 있어 다자적 조화가 필요하며 이를 위해 GATT 20조, SPS, TBT 협정이 적용될 수 있을 것이다. GM식품(Genetically Modified foods)의 안전성과 관련하여서는 여전히 논란이 여전히 끊이지 않고 있다. 더욱이, 우리나라가 GMO를 가장 많이 수입하는 국가라는 사실을 고려한다면 GM식품의 유해성을 차치하더라도 GM식품 관련 표시제도의 명확화 및 GM식품의 혼입기준에 대한 명확한 제시는 소비자들로 하여금 식품 선택에 있어 혼란을 해소할 수 있을 것이다. 따라서 본 논문은 GM식품에 대한 다자적·국내법적 고찰을 통해 우리나라 국내법에서 인용가능한 GM식품관련 법 및 주요 무역국의 국내법을 살펴봄으로써 우리나라 GM식품 표시방법에 대한 개선방안을 제시하고 한다.

  • In order to confirm the safety of a genetically modified organism (GMO), we assess its potential toxicity on non-target insects and spiders. In this study, the effects of GM soybean, a type of vitamin-A-enhanced transgenic soybean with tolerance to the herbicide glufosinate, were assessed under a field condition. The study compared this vitamin-A-enhanced transgenic soybean and a non-GM soybean (Gwangan) in a living modified organism (LMO) isolated field of Kyungpook National University (Gunwi) and the National Institute Agricultural Sciences (Jeonju) in the Republic of Korea in 2019 - 2020. In total, 207,760 individual insects and arachnids, representing 81 families and 13 orders, were collected during the study. From the two types of soybean fields, corresponding totals of 105,765 and 101,995 individuals from the vitamin-A-enhanced transgenic soybean and Gwangan samples areas were collected. An analysis of variance indicated no significant differences (p < 0.05). A multivariate analysis showed that the dominance and richness outcomes of plant-dwelling insects were similar. The data on insect species population densities were subjected to a principal component analysis (PCA) and an orthogonal partial least squares-discriminant analysis (OPLS-DA), which did not distinguish between the two varieties, i.e., the vitamin-A-enhanced transgenic soybean and the non-GM soybean in any cultivated field. However, the results of the PCA analysis could be divided overall into four groups based on the yearly survey areas. Therefore, there was no evidence for the different impact of vitamin A-enhanced transgenic soybean on the above-ground insects and spiders compared to non-GM soybean.

  • 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.

  • Genome walking is a par ticular application for identifying sequences of unknown genomic regions adjacent to a known region. Many genome walking methods based on polymerase chain reaction (PCR) are available. Even if earlier techniques suffer from low reproducibility, inefficiency, and non-specificity, improved strategies have been developed. In this study, we present an alternative strategy: the genomic DNA is digested with restriction enzymes. After cytosine overhangs at 5' ends, the fragments are ligated to linker adaptor s had guanine overhang at 3' ends. Then nested PCR is performed. The improvements in this strategy focus on two points. The first is the C tailing method using Pfu polymerase instead of the A tailing method based on nontemplate-dependent terminal transferase activity of Taq polymerase. Therefore unintended modification of target DNA can be prevented without A tailing error. The second point is the use of C/G-specific ligation had advantage in the ligation efficiency compared with A/T-specific ligation. Therefore, the C-G linker PCR method increases ligation efficiency between digested genomic DNA and adaptor DNA. As a result, the quantity of target DNA to amplify by PCR is enriched. We successfully used G-C linker PCR to retrieve flanking regions bordering the phophinothricin resistance gene in genetically modified tobacco (GMO).

  • The ornamental industry encompasses cut flower, pot plant, turfgrass and nursery stock production and is an important part of the agricultural sector. As internationally traded commodities, cut flowers and plants are an integral part of the economy of a number of developing countries in South America, the Caribbean and Africa. Genetic modification (GM) is a tool with great potential to the ornamental horticulture industry. The rapid progress in our knowledge of plant molecular biology can accelerate the breeding ornamental plants using recombinant DNA technology techniques. Not only is there the possibility of creating new, novel products the driver of the industry but also the potential to develop varieties requiring less chemical and energy inputs. As an important non-food agricultural sector the use of genetically modified (GM) ornamental crops may also be ideal for the intensive farming necessary to generate pharmaceuticals and other useful products in GM plants. To date, there are only a few ornamental GM products in development and only one, a carnation genetically modified for flower colour, in the marketplace. International Flower Developments, a joint venture between Florigene Ltd. in Australia and Suntory Ltd. of Japan, developed the GM carnations. These flowers are currently on sale in USA, Japan and Australia. The research, development and commercialization of these products are summarized. The long term prospects for ornamental GM products, like food crops, will be determined by the regulatory environment, and the acceptance of GM products in the marketplace. These critical factors will be analysed in the context of the current legislative environment, and likely public and industry opinion towards ornamental genetically modified organisms (GMO's).
