A survey on consumer’s awareness and perception toward genetically-modified (GM) foods was conducted on 2110 random samples of Korean consumers. More than 65% of the respondents were exposed to some information related to GM foods. The respondents answered that the greatest benefit of the development of GM foods is remedy of potential food shortages in the future. More than 90% of Korean consumers wanted GM foods to be labeled as such. More than 50% of the respondents would not buy until they know more about GM foods. Only 35.8% of Korean consumers were found to know that food items originating from plants contained genes. More consumers responded that they would not buy herbicide-resistant GM soybean but buy vitamin-enriched GM soybean. Many Korean consumers' decision of acceptance or rejection of GM foods depend not on the basis of biotechnology, but on the basis of the degree of benefit to the consumers. Only 6.4% of Korean consumers responded that GM foods were the greatest threat to the safety of Korean foods. The perception of Korean consumers on GM foods has not changed significantly during the past 5 years.

균형대체모형은 시장에 대한 외생적인 충격의 효과를 분석하는데 매우 유용한 분석 모형이고 그러한 이유 때문에 정부정책에 대한 효과 분석에도 빈번하게 이용되어 왔다. 거의 대부분의 균형대체모형을 이용한 선행 연구가 완전경쟁적인 시장을 가정하였다는 사실은 많은 경험적인 연구가 가공식품 시장은 불완전 경쟁구조라는 사실을 보여주고 있다는 점에 비추어 볼 때 가공식품 시장에 적용하는 데는 그 모형상의 한계 또는 결과에 대한 해석상의 한계를 안고 있다고 해야 할 것이다. 이 논문은 가공식품 시장에 적용할 수 있는 과점시장 균형대체모형을 이론적으로 제시하고자 하였다. 과점시장에서는 완전경쟁시장과 달리 공급곡선이 존재하지 않지만, 적절한 가정이 수반된다면 과점시장의 균형을 분석할 수 있는 공급관계 곡선을 도출 할 수 있다. 이 논문이 기존의 과점시장 모형에 관한 연구에 기여한 점은 과점시장의 균형점에서 공급탄성치가 도출이 가능하다는 것을 보여준 것이며, 과점시장의 공급탄성치는 시장구조 파라미터와 수요탄성치로부터 독립해서 존재하지 않는다는 점을 입증한 것이다. 이 논문에서 균형대체모형을 통해 제시한 보조금정책 분석 방법은 조세정책에도 그대로 응용될 수 있으며, 가공식품 산업 이외에도 1차 산품을 가공하는 다른 산업에도 적용될 수 있을 뿐만 아니라 환경오염과 관련된 이슈에도 적용이 가능하다.

To provide the research strategy for protection of children’s health from hazardous chemical, we reviewed the hazardous chemicals can be exposed through maternity, children's life style and living environment. Recently, diseases related with children’s living condition were focused as asthma, atopy, childhood developmental disability, congenital malformations and obesity. Children can be exposed to hazardous chemicals through an ambient air, water, soil, food, toys and other factors such as floor dust. Also children’s health was deeply related with a wrong life style and neglectful caring by a lack of knowledge and information of harmful ones at parents and child care center’s nursers. According to the previous study, the chemical risk factor of children’s health were identified as inorganic arsenic, bisphenol A, 2,4-D, dichlorvos, methylmercury, PCBs, pesticide, phthalates, PFOA/PFOS, vinyl chloride, et al. Domestic studies for identification of causality between children exposure to chemicals and resulted hazardous effects were not implemented. The confirmation of chemical risk factors through simultaneously performing toxicological analysis, human effect study, environmental/human monitoring, and risk assessment is needed for good risk management. And also, inter-agency collaboration and sharing information can support confirming scientific evidence and good decision making.

Choline is important an organic compound for normal membrane function, acetylcholine synthesis, lipid transport, and methyl metabolism. In biological tissues and foods, there are multiple choline compounds that contribute to choline content. There are so many analytical methods for choline determination, such as radioisotopic, high-performance liquid chromatography, and gas chromatography/mass spectrometry. However, these existing methods are expensive, unmanageable, and time-consuming. In this study, we modified enzymatic method, which is applicable for the determination of choline in milk and infant formulas, and applied to bovine serum and muscle. The calibration curves were linear with higher correlation coefficients than 0.994 . Recoveries obtained by calibration curves from the spiked bovine serum and muscle samples varied between 70.6 and 85.2%. The method may be suitable for use as a routine method in the determination of choline for biological tissue and food samples.
