Recently, the environment has been recognized as an important factor in increasing competitiveness in the industry. In agriculture and rural areas, the environment is becoming important in terms of the competitive advantage of agricultural products and continued regional development. This study intended to provide farmers with basic data for the continuous development of local agriculture through exploratory studies of environmental behaviors and regional development. In this study, 107 questionnaires were used for analysis of farmers in Jinan County to analyze the impact of farmers' environmental consciousness on regional development, and the research model was verified using a structural equation model. As a result of the analysis, it was analyzed that among the components of the environmental consciousness of farmers, environmental health has a statistically significant positive effect on environmental behaviors, while environmental interest and soil environment do not have an impact. The environmental behaviors of farmers have not been shown to be statistically significant to regional development. As a result of the analysis of this research, first, it is necessary to foster at the local level by establishing a customized fostering system for each village and region, such as education and technical support to vitalize the participation of young farmers and small and medium-sized farmers through the establishment of an Eco-friendly agricultural organization support system. It is necessary to raise public awareness of the public good function of agriculture and expand opportunities for sharing the value of Eco-friendly agriculture.

Recent trends of global food production, processing, distribution and preparation under free trade circumstance are creating an increase in common' concerns about food safety. It is important that farmers improve agricultural products/food safety for satisfying consumer needs and health. Cognizant to the situation, this study was conducted to analyze how the Producers gather information, and determine their awareness about agricultural Products safety using a safety Questionnaire. The Questionnaire was given to 500 farmers who cultivate rice, fruit trees, vegetables, and other crops from September through October 2005. More than half of the producers felt concerns about the agricultural products/foods safety. Uneasiness of the producers was higher amongst those who were younger and earned a higher income. Pesticides and zoonosis (BSE AI, etc.) emerged as the main risk factors causing concerns among the greatest number of producers. Producers had a positive opinion of the effects and perception of food safety, but no opinion of the activity of government. The producers showed a high level of understanding of the Country of Origin Labeling System (88.2%), the quality certification system of agricultural and livestock products (71.9%), and the raising system of environment-friendly agriculture (72.7%). However, their level of understanding of the GAP (59.3%) and the Traceability System (22.8%) was still low. To effectively implement these policies, awareness of producers who are the beneficiaries of the above policies has to be enhanced. Therefore, the safety information should be provided at a more appropriate time and should be easier to understand.

The materials of artificial soils in the production process of container seedlings have a great influence on plant growth. Peat moss, vermiculite, and perlite have been used as major components of artificial soils for many years; however, they could decrease carbon fixation carried out by the soil and cause environmental problems such as a change in the water quality. Thus, environmental friendly materials to replace them must be developed. The purpose of this study was to verify the optimum additive materials of artificial soils and their mixed ratios for the growth and seedling quality index (SQI) of Quercus serrata. Rice husk, mushroom sawdust, and pine bark were each used as an additive material and mixed into the growth medium at 10% and 20% of the total volume. There was no significant difference in the height growth of Q. serrata. The 20% mushroom sawdust decreased the root collar diameter by 23.4% compared to the control. The total dry weight was highest with the 10% rice husk and was significantly lower by 10.3% for the 20% mushroom sawdust compared to the control. Additionally, the SQI for all the treatments showed no tendency to increase compared with the control. Thus, this study showed the possibility of recycling biomaterials from agriculture and forest for seedling production. This method could reduce environmental problems and help eco-friendly nurseries to achieve a carbon negative impact by the recycling of by-products.

The purpose of this paper is to analyze the relationship between the level of satisfaction of domestic Environment-friendly agricultural products and purchase intent of imported organic products. To accomplish the objective of the study a consumer survey was administered for quantitative analysis regarding consumption patterns. The bivariate probit with sample selection model was employed for empirical analysis on the relationship. The estimation results showed that to increase continuously the consumption, it is necessary to improve the quality satisfaction compared to the price, and that it is also necessary to increase the reliability of the certification system and the awareness that the consumption is helpful for health promotion to increase the quality satisfaction compared to price. In addition, it was concluded that in order to induce the purchase of domestic organic products rather than imported organic products, efforts to improve the safety of domestic products, remove the risk of residual pesticides, and increase the reliability of domestic products compared to imported products are needed. Therefore, to reduce the proportion of purchases of imported organic products and increase the consumption of domestic products, raising awareness that the consumption is conducive to health promotion, enhancing the safety of domestic products, and providing accurate information on the safety of imported products are required.

BACKGROUND: The residual analysis of polar pesticides has remained a challenge. It is even more difficult to simultaneously analyze multiple polar pesticides. Diquat, paraquat, and chlormequat are typical examples of highly polar pesticides. The existing methods for the analysis of diquat, paraquat and chlormequat are complex and time consuming. Therefore, a simple, quick and effective method was developed in the represent study for simultaneous analysis of diquat, paraquat and chlormequat in animal products, meat and fat using UPLC-MS/MS. METHODS AND RESULTS: Sample extraction was carried out using acidified acetonitrile and water and re- extracted with acidified acetonitrile and combine the extracts followed by centrifugation. The extract was then cleaned up with a HLB cartridge after reconstitution with acidic acetonitrile and water. The method was validated in quintuplicate at three different concentrations. The limits of detection (LOD) and quantification (LOQ) were 0.0015 and 0.005 mg/L, respectively. Matrix suppression effect was observed for all of the analytes. A seven point matrix matched calibration curve was constructed for each of the compound resulted excellent linearity with determination coefficients (R2) ≥ 0.991. Accuracy and precision of the method was calculated from the recovery and repeatability and ranged from 62.4 to 119.7% with relative standard deviation less than 18.8%. CONCLUSION: The recovery and repeatability of the developed method were in the acceptable range according to the Codex Alimentarius guideline. The developed method can be applied for the routine monitoring of diquat, paraquat, and chlormequat in animal products, meat and fat.

So far, we have pursued only convenient and efficient growth of economy, as a result, environment surrounding us has been destroyed and the rights of our existence gotten to be even threatened. We need to ensure our lives and at the same time, need a power with which agriculture undertakes global circulation structure and a power that is able to preserve our environment we live per so. Therefore, in the near future, the final objectives of agriculture structure for 21st century would be to increase productivity of highly developed agricultural products in accordance with the ecosystem and a recycling agriculture. What is a recycling agriculture\ulcorner In the narrow sense, it means provisions-producing- system related to interactive recycle of material among forestry, livestock husbandry and seeding agriculture. In the broad sense, it means to produce credible agricultural product by keeping balanced resources via conversion to complete degradable material of organic wastes produce within rural village. Based on this concept, finally, our goal is to construct the resources recycling community. Environment friendly agriculture ⇒ organic agriculture ⇒ recycling (circulation) agriculture ⇒ construction of community with resources recycling. Therefore, in order to construct recycling agriculture, most of all, it is considered that the following, it should be established reasonable standard amounts for fertilizer, manure and liquid fertilizer based on results of soil test by each region, nature-recycling form of crops production and livestock production systems by maximizing utilization of different recycling byproducts occurring in the crop producing process by each region.

The objective of this study is to investigate the perception and satisfaction of elementary and middle school students on free school food service. We surveyed education related to school food service, concerns about food ingredients, perceptions of free school food service and satisfaction for the quality of the school food service. The investigation is classified into two groups, schools that operate as a food service center or those that do not. Those who are provided food ingredients by school food service centers are educated about the agricultural products' country-of-origin and their environment-friendly food service. The more individuals are educated of the foods' county-of-origin and environment-friendly food service the more they will have a higher concern of the food materials and subsequently a higher satisfaction for the quality of school food service. School food service centers managed directly by the local government would probably receive higher satisfaction than those consigned to a private sector. The results of this study will be meaningful to establish policies on school food service and school food service centers.
