Recently, it is expected that the agricultural and stockbreeding industry are damaged by the China-Japan-South Korea FTA and FTA between the United States and South Korea. After free trade, it is increasing to import crops, aquatic products, and livestock which are produced in a foreign land. But it is affected negatively to the trust relationships and markets, because of breaking it out that low grade foreign products are turned into domestic products. For this reason, we need the traceability management system. In this paper, it designs and implements the traceability management system using RFID and USN providing distribution traceability information as well as the traceability information of the growth environment, automatic control according to the facility growing and monitoring of the storehouse. The implemented whole systems consist of the growth environment monitoring and the traceability management. First, the growth environment monitoring shows the environment of plantation and automatic controller of the storehouse and growing facility. This growth environment monitoring information provides the detailed information about growth environment and writing the farming diary automatically by producer. Second, the traceability management provides all of the traceability information such as production, shipment and consumption to consumers. The traceability management system that has been designed and implemented using RFID and USN in this paper, provides the u-IT agriculture to producer and the reliability about agricultural products. In addition, this system provides the foundation data to operate GAP and HACCP, and becomes the advantaged agricultural products of the interior of a country by application of this system.

The restaurants have been forced to inform the origin of ingredients to consumers due to the origin obligation policy enacted in 2008 October. However, it is difficult to trust the policy because the origin is represented by a manager's conscience. Therefore, in order to provide consumers with reliable information, we have designed, and embodied the agricultural management system using RFID and USN technology. By installing system on agricultural plantations this system not only manages environmental data such as temperature, illumination and humidity collected in real time but also offers consumers the information of fertilizers or pesticides sprayed on the crops. Before purchasing, consumers will be able to check raw flesh process and the fertilizer and agricultural chemical scattering scene of the crops as an image by using RFID tags with a leader, which more increase the reliability.

관행재배 농산물에 대한 유기재배 농산물의 우수성이 구전되고 있으나 객관적인 과학적 데이터가 부족한 실정이다. 그래서 본 연구에서는 한국인이 주식으로 하고 있는 쌀(동진 1호)을 대상으로 생산이력이 분명한 유기 및 관행재배 시료를 이용하여 독자적으로 확립한 분석법을 이용해 유기 및 관행재배 쌀에 함유된 생리활성성분의 함량 비교를 행하였다. 생리활성성분 분석은 $\gamma$-oryzanol, $\beta$-sitosterol 및 tocopherol류를 대상으로 행하였다. 쌀에 함유된 주요 4종의 $\gamma$-oryzanol류의 동정을 위해 그 4종 화합물들을 ESI-MS 및 NMR 분석을 행한 결과, ODS 컬럼 상에서 cycloartenyl ferulate, 24-methylene cycloartenyl ferulate, campesteryl ferulate 및 $\beta$-sitosteryl ferulate 순으로 용출됨을 확인하였다. 동정된 각 성분들을 HPLC로 분석한 결과, cycloartenyl ferulate와 $\beta$-sitosteryl ferulate의 함량은관행보다 유기재배 쌀에서 유의(p<0.05)하게 높은 값을 보였다. 또한 $\gamma$-oryzanol 중 24-methylene cycloartenyl ferulate와 campesteryl ferulate의 함량은 유의차는 인정되지 않았으나 관행보다 유기재배 쌀에서 더 높은 경향을 보였다. 그리고 $\beta$-sitosterol 함량에 있어서는 유의차가 인정되지 않았으나 관행보다 유기재배 쌀에서 더 높은 경향을 나타냈다. 관행재배와 유기재배 쌀의 tocopherol류의 함량을 분석한 결과, $\alpha$-tocopherol의 함량에 있어서는 관행과 유기재배 쌀 간의 유의차가 관찰되지 않았고, $\beta$- and/or $\gamma$-tocopherols의 함량에 있어서는 유기재배 쌀에서 더 높은 경향이 관찰되었다. 이처럼 쌀에 함유된 생리활성 성분과 그로 인해 발휘되는 기능성 측면에 있어서 유기농산물의 우수성은 유기농산물 재배 농가의 수익 창출에 도움이 되는 홍보자료 제공 및 식품 기능학적 측면에 있어 중요한 기초자료로 활용될 수 있으리라 기대된다. 그러나 본 결과는 본 실험에서 대상으로 한 시료에 한정될 수 있으며, 유기재배 방법과 재배환경 및 조건에 따라 다양한 결과가 얻어질 수 있음에 주의가 요구된다.

Recently, there has been much research and many attempts to enhance converged information technology services using new technology such as ubiquitous sensor networks (USN) in medical, environmental, industrial, and logistic areas. There has also been much research and various attempts to apply this new technology to agricultural areas. However, applications to the agricultural areas should be considered differently against the same areas such as medical, environmental, industrial, and logistics. Therefore, this paper suggests that an agricultural cultivating management and traceability system. This system is a unified system that supports the processes sowing seeds through selling agricultural products to consumers. Farmers can be provided with an effective calendar for cultivation and weather information in real time as well as the monitoring of the growth of farm products on the farm in real time using this system. Farmers can also control all equipment installed on the farm directly or remotely and the equipment can be controlled automatically when the measured values such as temperature and humidity deviate from the decent criteria which are set by farmers or this system. Additionally, the reliability for and the better quality of the agricultural products can be improved because farmers can use this unified system to cover all processes from sowing seeds to selling to consumers.
