The paper analyzes GMO legal system and the problems of its management in China and their suggestions to Korea. GMO has been arising as a principal alternative of grain while grain prices continue to climb. Although there has been concerns about GMO imported from China, it is true that we have not studied on China's legal system and the problems of its management in China. The paper believes that when Chinese government does not manage GMO primarily, we have a high possibility that China's GMO food will access to Korean market at any time, and threaten our health and safety. Hence, it is highly time to analyze how legally China treats GMO and what the problems of its management are. The paper found out problems of China's GMO management in three ways. Firstly, GMO legal system of China is confused and it has limitation of effectiveness. China has no regulations like "a law" to regulate GMO and regulations which exists now are not easy to apply in substance. Secondly, China has no administrative strictness to manage GMO. For example, the regulation which ministry of agriculture in China promulgated in March of 2002 started to use partially since 2003, 7. Thirdly, China, as a nation that administration superiors to, market does not do its roll to control GMO. It relates to the low concerns and care of Chines people about GMO. The paper shows suggestions and countermeasures according to problems of China's GMO management.

GMO labeling system in South Korea stipulates three labeling methods: GMO labeling, no labeling and Non-GMO labeling. Products labeled as Non-GMO are not allowed for unintentional commingling of GMO without tolerance. However, consumers vary their acceptance of Non-GMO label on the unintentionally commingled products and willingness to pay according to the mixing rate, rather than devalue the whole products as useless. Additionally, consumers do not believe that the acceptable mixing rate should be discriminated between non-labeled products, which allow up to 3% of unintentional GMO contamination, and Non-GMO labeled products. Information on unintentional GMO mixing mainly refers to the mixing rate, but the Non-GMO content remaining even after commingling is also important information. The decline in value is alleviated when consumers are exposed to positive information, such as Non-GMO content, rather than when exposed to negative information, such as the mixing rate. Loss Aversion Coefficient is relative depending on whether the information representing the loss is positive or negative. Information that a Non-GMO labeled product contains X% GMO is more sensitive than information that (100-X)% Non-GMO remains.

The goal of this study was to examine the effects of perceived risks toward GMO (Genetically Modified Organism) food on the decision-making to purchase it and demands to reveal its Identity. The major results were as follows. First, consumers strongly perceived the risk toward GMO food, and demanded labeling to identify it. But, many consumers had indecisive in the purchase of GMO food. Second, consumers with high level of perceived risks toward GMO food were more likely not to buy GMO food. In addition, the level of perceived risk was high among consumers who had many children. Finally, consumers with high level of perceived risks toward GMO food were more likely to demand the labelling for identifying GMO food. Consumers who had many children and high level of reliability for labelling food safety strongly demanded to label for revealing GMO food.

본 연구는 과학기술 위험이슈로서 GMO에 대한 보도경향을 확인하기 위해 조선일보, 한겨레를 대상으로 1994~2015년까지 GMO 관련 기사를 내용 분석하였다. 분석 결과, 'GMO 기술 도입기(1994-2000)', 'GMO 기술 발전기(2001-2010)', 'GMO 사회 수용기(2011-2015)'의 세 시기별로 '위험', '불안/염려'라는 주제가 지속적으로 중요주제로 취급되고 있었고, 심층성이나 취재기자 전문성에서는 모든 시기에서 부족함이 드러났다. 이념적 지향점이 다른 언론 간 비교에서는 조선일보가 한겨레에 비해 보도주제, 논조 등에서 GMO에 대한 신(親)기술적 성향이 강한 것으로 확인되었다. 또한, 보도논조에 따른 '위험-편익'주제와의 관계를 확인한 결과, 부정적 논조의 보도들은 GMO의 위험-편익에 있어서 '위험'을 긍정적 논조의 보도들은 GMO의 위험-편익에 있어서 '편익'을 중요하게 다루고 있었다. 본 연구를 통해 과학기술 위험논쟁의 대중인식에 있어 바로미터가 되는 국내 과학저널리즘의 주제편향성, 비전문성 등의 문제점 개선을 제언할 수 있겠다.

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.

Objective: This study was conducted to compare growth performance, nutrient digestibility and meat quality of broilers fed a genetically modified organism (GMO) diet or a non-GMO diet. Methods: A total of 840 broilers with an initial body weight of 43.03 g per chick were randomly allocated into 1 of the following 2 dietary treatments lasted for 32 days (15 broilers per pen with 28 replicates per treatment): i) Trt 1, GMO maize-soybean meal based diet; ii) Trt 2, non-GMO maize soybean meal based diet. Both diets were maize-soybean meal diets. The GMO qualitative analysis, proximate analysis and amino acid analysis of the feed ingredient samples were carried out. Diets were formulated based on a nutrient matrix derived from analysis results. Growth performance was measured on day 0, 7, 17, and 32. And all other response criteria were measured on day 32. Results: The analysis results showed that the total Lys, Met, Thr of non-GMO grains were lower than that of GMO grains, the protein content of GMO soybean meal was higher than that of non-GMO soybean meal. Feed intake and feed conversion rate (FCR) were greater (p<0.05) in broilers provided with non-GMO diet than that of the GMO group from d 17 to 32. A decrease in FCR was observed in birds fed the GMO diet through the entire experiment (p<0.05). No significant impacts on blood profile, meat quality and nutrient digestibility were found in response to dietary treatments throughout the experimental period (p>0.05). Conclusion: These results indicated that non-GMO diet showed a negative effect on growth performance but nutrient digestibility, blood profile, carcass weight and meat quality were not affected by non-GMO diets.

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.

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.

프탈레이트계 PVC 가소제를 대체하기 위해 식물유 기반 아세틸화 모노글리세라이드(AMG)계 가소제를 합성하여 PVC에 대한 가소성능을 평가하였다. 코코넛 오일과 글리세롤로부터 전이 에스테르화 반응과 아세틸화 반응을 거쳐 AMG-CoCo를 합성하였고 글리세롤 모노올리에이트(GMO)로부터 아세틸화 반응을 통해 AMG-GMO를 그리고 추가적으로 에폭시화 반응을 거쳐 AMG-GMO-Epoxy 합성하고 그 구조들을 확인하였다. AMG계 가소제의 열안정성을 평가한 결과, AMG-CoCo < AMG-GMO < AMG-GMO-Epoxy 순으로 열분해 온도가 높았으며 모두 상용 가소제인 DOP의 열분해 온도보다 높았다. AMG계 가소제를 함유한 PVC의 경우, 인장 신율은 770~810%, 인장 강도는 약 19~22 MPa로 DOP로 가소화된 PVC보다 우수하였다. DMA 분석 결과, AMG-GMO-Epoxy와 PVC는 매우 우수한 섞임성을 보여주었고 AMG-GMO-Epoxy를 50 phr 함유한 PVC의 $T_g$는 $24^{\circ}C$까지 감소하였다. 물에 대한 가소제의 용출 실험 결과, AMG-GMO와 AMG-GMO-Epoxy를 50 phr 포함한 PVC 경우 무게 감소가 약 2%와 1%로 내용출성이 매우 우수함을 알 수 있었다. 따라서 AMG-GMO-Epoxy가 DOP를 대체할 PVC 가소제로 경쟁력이 있다고 할 수 있다.

This work was conducted to observe the housewives´ recognition about GMO products and their opinions about the development and production of GMO. Seventy eight percent of the subjects in this study were aware of GMO and GMO product which is best known to them was bean. Only 6.2% of the subjects considered GMO as safe and 42.1% did not know whether it is safe or not. Most of the subjects were unlikely to choose to purchase the GMO because of unproved safety, but many subjects were willing to purchase if the safety was informed with high reliability, even though 25.9% of the subjects were still negative. But when GMO product is offered with low price compared with ordinary products, only 24.6% were willing to purchase, showing that the safety was considered more important than the low price.
