In this paper, the traceability system for rice which is based on RFID technology is introduced. The traceability system plays an important role in the quality management for rice and rice-related food since this system can provide the information of all food chain (production, treatment, distribution and sales etc.) and more quickly identify the cause of the rice and rice-related accident. The main result of the this paper is the basic structure for the traceability system based on RFID technology. To show the implementation case based on this basic structure, the effectiveness of the traceability system is verified. In addition, the prerequisites condition for effective implementation is proposed.
In order to monitor the levels of pesticides in environment-friendly stalk and stem vegetables and leafy vegetables selling at markets in Korea. A total of 637 (395 organic agricultural products, 242 pesticide-free agricultural products) samples of 21 stalk and stem vegetables and leafy vegetables were collected twice from markets in July and August 2010 in Korea. Pesticide residues in samples were analyzed by multiresidue method for 240 pesticides using GC-ECD/NPD and HPLC-DAD/FLD. The suspected-pesticides were confirmed with a GC-MSD. As a result of analysis, six pesticides were detected from eight samples, representing a detection rate of 1.3% and amounts of pesticide residues in samples were as follows: alachlor 0.043, chlorfenapyr 0.022-0.324, diazinon 0.024, dicofol 0.009-0.138, dithiopyr 0.008, metolachlor 0.025 mg/kg. Their residue levels were below the MRLs. Estimated daily intakes (EDIs) of the pesticides detected from stalk and stem vegetables and leafy vegetables were less than 25% of their acceptable daily intakes (ADIs), representing that residue levels of the pesticides detected were evaluated as safe for consumption. However, five samples containing pesticide residues were unsuitable environment-friendly products because of pesticides detected more than their 10% MRLs in organic and pesticide-free agricultural products.
This study found that was done to find the commercial and physical distribution system of the agricultural physical distribution center of the agricultural co-operation and considers the receipt region of agricultural, livestock and marine products of the agricultural physical distribution center established for the efficiency and integration of physical distribution by season. And this study clarified the relationship between regional characteristics and regional types of distribution in accordance with the sales of each product. According to the research, the agricultural physical distribution center of Cheongju agricultural co-operation receives agricultural, livestock and marine products from all over the country as the core region in Chungcheongbuk-do and deliveries mainly to some regions in Chungcheongbuk-do, Chungcheongnam-do and Daejeon city. That's e agricultural, livestock and marine products that the agricultural physical distribution center of the agricultural co-operation deals with the required freshness. Therefore, the physical distribution center forms the regional physical distribution system to mainly receive products from the regions where are relatively near the center and to delivery to the nearby region. This delivery of agricultural, livestock and marine product significantly influences the sales strategy as well as the economic principles of demand and supply.
Agriculture is a primary industry that influenced by the weather or meterological factors more than other industry. Global warming and worldwide climate changes, and unusual weather phenomena are fatal in agricultural industry and human life. Therefore, many previous studies have been made to find the relationship between weather and the productivity of agriculture. Meterological factors also influence on the distribution of agricultural product. For example, price of agricultural product is determined in the market, and also influenced by the weather of the market. However, there is only a few study was made to find this link. The objective of this study is to investigate the effects of meterological factors on the distribution of agricultural products, focusing on the distribution of chinese cabbages. Chinese cabbage is a main ingredient of Kimchi, and basic essential vegetable in Korean dinner table. However, the production of chinese cabbages is influenced by weather and very fluctuating so that the variation of its price is so unstable. Therefore, both consumers and farmers do not feel comfortable at the unstable price of chinese cabbages. In this study, we analyze the real transaction data of chinese cabbage in wholesale markets and meterological factors depending on the variety and geography. We collect and analyze data of meterological factors such as temperatures, humidity, cloudiness, rainfall, snowfall, wind speed, insolation, sunshine duration in producing and consuming region of chinese cabbages. The result of this study shows that the meterological factors such as temperature and humidity significantly influence on the volume and price of chinese cabbage transaction in wholesale market. Especially, the weather of consuming region has greater correlation effects on transaction than that of producing region in all types of chinese cabbages. Among the whole agricultural lifecycle of chinese cabbages, 'seeding - harvest - shipment - wholesale', meterological factors such as temperature and rainfall in shipment and wholesale period are significantly correlated with transaction volume and price of crops. Based on the result of correlation analysis, we make a regression analysis to verify the meterological factors' effects on the volume and price of chines cabbage transaction in wholesale market. The results of stepwise regression analysis are shown in
