Imidacloprid is a neonicotinoid insecticide widely used for insect control in a variety of crops. The evaluation of imidacloprid total residues in animal feeds derived from crop by-products is required to ensure the safety of livestock products. We performed simultaneous LC/MS/MS analyses of imidacloprid and its metabolites in five different livestock products including beef, pork, chicken, milk and egg from domestic markets. The methods for sample preparation and instrumental analysis were established by modifying QuEChERS method to meet the Codex guidelines. The methods generated 0.0035 mg/kg of the limit of determination (LOD), 0.01 mg/kg of the limit of quantitation (LOQ) and standard calibration linearity with >0.983 of the coefficients of determination (R²). The methods exhibited the recovery values of imidacloprid and its metabolites ranging from 65.66 to 119.27% without any interference between matrices. Imidacloprid total residues in the livestock products were found as values lower than the LOQ and maximum residue limits (MRLs). This study suggests that the methods are successfully applicable for the safety evaluation of imidacloprid total residues in livestock products from domestic markets.

본 연구에서는 유통 중인 분말 농산물가공품의 안전성확보를 위하여 대형마트, 온라인 쇼핑몰에서 수거한 104건을 대상으로 다종농약다성분분석법으로 검사 가능한 잔류농약 373종 및 금속성 이물을 검사하였다. 품목별 수거현황은 향신식물 33건(31.7%), 과일류 31건(29.8%), 채소류 25건(24.0%), 서류 5건(4.8%) 순이었다. 잔류농약은 전체 104건 중 7건에서 잔류허용기준 이내로 검출되어 6.7%의 검출률을 보였으며 기준을 초과한 부적합 제품은 없었다. 깔라만시분말에서 chlorpyrifos, malathion, permethrin, 노니분말에서 fenoxanil, 쑥분말에서 tebuconazole, 파프리카분말에서 tetraconazole, 신선초분말에서 etofenprox가 검출되었는데 이는 농산물중의 잔류농약이 가공품으로 이행되었을 것으로 보인다. 금속성 이물은 22.1%(23건)의 검출률을 보였으며 기준을 초과한 제품은 계피분말, 강황분말, 새싹보리분말, 쑥분말 등 16건이 발생하여 분말 농산물가공품에서는 금속성이물의 관리가 무엇보다 중요할 것으로 판단된다. 금속성 이물(쇳가루)은 단단한 건조 농산물을 분말로 만드는 분쇄과정에서 금속성 재질의 롤밀, 칼날 등의 마찰로 인해 미세한 쇳가루가 발생하면서 분말 농산물가공품에 섞여 들어가는 것으로 추정된다. 분말 농산물가공품의 안전관리를 위해서는 원재료인 농산물의 안전성 확보를 기본으로 건조원료의 분쇄과정 중 발생하는 금속성 이물의 최소화, 금속성 이물 제거 장치의 설치, 분말 농산물가공품의 정기적인 모니터링 등의 체계적인 관리를 통해 제품의 안전성을 확보할 수 있을 것으로 기대된다.

In this study the effect caused by limited storage lift of agricultural products for determining shipping amount can be analyzed by $l^{st}$ order autoregressive model based on cobweb theorem. Carrying capacity and auction price of upland-grown cabbage and garlic from 2000 to 2003 in wholesale markets were used for analysis. In result regression models of cabbage can not be used in verification periods although those of garlic approximately predicted shipping amounts in verification periods. It can be inferred that it is hard to control shipping amounts depending on price fluctuation for agricultural products which have limited storage life so cultivated areas and meteorological risk should be managed for stable price.

Sustainable agriculture in Korea will gain important momentum by implementing The Direct Payment Scheme for Environmentally Friendly Agriculture in 1999. The farmers who want to participate in the program will be paid 530,000won/ha directly by the Government in return for engaging sustainable agriculture. The policy scheme which is a pilot program will be restricted to environmentally regulated areas to apply such as water supply protection zone, environmental protection districts and national parks. As a consequence of the policy, the supply of transitional organic agricultural products is expected to increase significantly. However the increased supply of low input agricultural products may have difficulties to find an appropriate marketing channel which is differentiated from the general agricultural product market. Development of an open market system for mass transaction of the low imput agricultural products is necessary. Also various government programs and projects which are designed for clean environment and regional community development must be integrated into the sustainable agriculture program to have synergy effects.

This study aimed to analyze socioeconomic effect of eco-friendly free school food supply system by Seoul, which has been consistently extended since 2011. To do so, effect of eco-friendly free school food supply system on the beneficiaries, Seoul citizens, was analyzed by using 'labor & income panel', while that on rural society was analyzed by using the surveys on the eco-friendly agricultural product supply performance by the 'Eco-friendly Agricultural Products Retail Center' as well as for students, school parents, nutrition teachers and nutritionists. The results of analysis showed that eco-friendly school food supply system contributes to income redistribution among the Seoul citizens to a certain extent, provides the eco-friendly agricultural product producers in the rural society with the stable market, and positively influences them to secure stable incomes. In addition, eco-friendly free school food reduced the amount of carbon emissions through the use of environmentally friendly agricultural products resulting in environmental improvements and economic benefits. Considering such effects, free school food supply using the eco-friendly agricultural products needs to be consistently maintained in the future without politic change by political ideology and to be extended to middle school level in medium and short-term.

The purpose of this study was to compare the degree of understanding about school foodservice management and environmentally friendly agricultural products between urban and rural elementary school children's mothers. The subjects were 280 elementary school children's mothers who lived in Gunsan city and the nearby countryside. The results are summarized as follows. The mothers in urban schools were higher on the degree of participation (p < 0.01) and interest (p < 0.01), but were lower on the degree of satisfaction (p < 0.001) for school foodservice than rural ones. The best improvement of school foodservice management was improving food tastes and qualities of the foodstuffs in urban schools and sanitation at the service area in the rural schools (p < 0.001). The school foodservice program contributed to cure the unbalanced diets and developing of bodies and minds; there was no difference of urban and rural schools. But eating habits in rural schools were more improved than urban schools (p < 0.001). The primary reason for using environmentally friendly agricultural products was to improve their health and in securing safe foods, there was no difference of urban and rural schools, but generating the farmer's income from the products in rural schools was higher than urban schools (p < 0.001). There are conflicting views between urban and rural schools for the additional costs brought by using the environmentally friendly agricultural products (p < 0.001). The order of preference on using environmentally friendly agricultural products was rice and various grains, vegetables, fruits, livestock, seasoning, etc. In conclusion, our central and local governments should change their roles in financially positive ways and reflect the issues in making the policy effective. Responsible administrators of school food suppliers run the system more faithfully with the above government support.

Moisture loss of fresh fruits and vegetables is a main cause of deterioration. It resulted not only in the direct quantitative loss, but also in change in appearance, texture and nutrition. To reduce the loss of moisture content during the distribution in the market, fresh products are packaged using plastic films. But, most of the fresh products are packaged manually in Korea. In order to minimize the labor requirement, the packaging machine for fruits and vegetables was developed and tested. Prototype was composed of film feeding unit, bag former, products feeding conveyor, film feeding roller, center sealer, end sealer and discharge conveyor. Green peppers, carrots and perilla leaves were tested with prototype. Prototype could pack 1780, 1390, 1780 bags per hour at the feeding speed of 0.08m/s respectively and 2250, 1810, 2640bags per hour at the feeding speed of 0.10m/s respectively. And packaging speed of green peppers and carrots was improved by 3.7 and 3.4 times compared with manual packaging. The packaging condition with the prototype was good and the products had almost no damages.
