This study analyzed the status of urban agricultural regulation of metropolitan governments on supporting multi-dimensional values to suggest a direction for improving urban agriculture regulations. Moreover, a Delphi survey was conducted to derive ways to identify improvement opportunities for functions that showed relatively insufficient support for urban agricultural regulations. As a result of the study, 12 out of 17 metropolitan governments and 116 of 226 municipalities have enacted urban agricultural regulations. However, the enactment of urban agricultural regulations has generally declined since 2011. Analysis of the contents of the urban agricultural regulations showed that they focused on matters relating to the creation and expansion of the foundation of urban agriculture. Among the multi-dimensional values of urban agricultural regulations, the foundation for supporting the securing of green spaces and utilizing food production functions was most widely available. On the other hand, the foundation for support of resource recycling, healing and health, social welfare, economic imbalance mitigation, and job creation functions has been shown to be relatively insufficient. A Delphi survey conducted to determine potential measures to improve urban agricultural regulations to support these functions found that 17 of the 18 ordinance improvement measures were valid. Therefore, to revitalize the multi-dimensional values of urban agriculture, it is first necessary to enact new ordinances. Also, to revitalize the multi-dimensional values of urban agriculture evenly, it is necessary to revise the ordinances to include resource recycling, healing and health, social welfare, mitigation of economic imbalances, and job creation functions. In this process, the development of urban agriculture technology, legal review of various urban farming spaces, and fostering of industries related to urban agriculture are necessary. Above all, steady interest in the multi-dimensional values of urban agriculture and the efforts of local governments to foster urban agriculture must be supported.

This article will divide agricultural change process in Yanbian area into the period of japan rule, socialism and later time of the reform and open policy and so on. It will analyze the changes of Yanbian agriculture in every period influenced by external environment influence. The conclusions are as follow: first, under the influence of the japan rule, the policy about Korean Minority immigrants in japan and the original work agriculture and the group tribe construction, Yanbian fanning was controlled by the Japanese. Therefore, Yanbian's agriculture became the tool to satisfy the war and plunder the resource for Japanese. It shows the obviously peripheral characteristics. Second, in socialism time, Yanbian's agriculture was influenced by the rural communalization. The fanning completely belongs to the country, the agricultural production is influenced by the idea of "grain as the key link" which it only pays attention to take the cultivation industry and the production of grain in the interior of cultivation industry. Therefore, it has not been able fully to use the rich natural resource. Third, after reform and open policy, the countrysides were implemented family contract responsibility system, the farmer can rent the land for a long time, and the enthusiasm of agricultural production was improved. Moreover, due to the social market economy-system, the farmer carried on the agricultural production activities according to the market's demands and various departments of the agriculture obtained the coordinate development.

Currently, rural labor markets are undergoing a structural change in which the proportion of non-agricultural industries is increasing, instead of decreasing the proportion of agriculture. The purpose of this study is to propose policy for job creation in rural areas through analyzing the employment situation in Rural Korea in the context of this structural change. Using the Census of Agriculture, Farm Household Economy Survey, we analyzed the increase of low income farmers and self-employed farmers. We analyzed the changes of non-farm employment in rural areas using the Census on Establishment. The main results of the study are as follows. First, farms' pathways are very diverse by the levels of income from their own farming and other gainful activities. It is necessary to implement policies that take into account the development pathways of farm household. Second, most of the farms are in low-income and self-employment status. In order to increase their incomes, it is necessary to increase non-farm income earning policy. The rural non-farm economy is becoming increasingly important in rural Korea. The growth of the non-farm economy will be crucially important when it comes to creating new jobs in rural areas in rural Korea. Third, it is necessary to provide systematic support for rural entrepreneurship as a core policy for expanding jobs beyond agriculture. Rural entrepreneurship has the potential to drive innovations that can reduce poverty and create employment. Fourth, there is a need for measures to increase jobs in the welfare field, which is growing fastest in recent years. In the welfare field, we can find vigorous collective actions in some rural communities such as community business, cooperative movement and various community development activities. Those activities will help increase the employment of aged farmers and low-income farm household.

The nonpoint pollution source (NPS) is irregular in the amount of generated and runoff. About 70% of the water pollution sources in Korea are NPS. Most of the rural areas are small towns with less than 50 families. This is where sewerage supply is poor. This is where the domestic swage of the house flows directly into the small stream. This study investigated the amount and concentration of domestic swage. And investigated NPS for public officials. We have suggested an improvement plan here. Local government officials lack the concept of NPS. Rural residents also do not know about NPS. Therefore, we proposed NPS public relations and education linked to public administration. This is an extension of the national budget and interest. The domestic swage is discharged at about 272 liters per day in a house. We proposed the introduction of small facilities. If the capacity remains, it is suggested to link to cattle shed, pigsty and so on. The BOD, COD, TN, TP, and SS concentrations were all high. This suggested a reduction in concentration in combination with natural water. Finally, NPS facilities were proposed to be put into rural areas. And it was determined that continuous monitoring was necessary. The results of this study were expected to be applied to NPS management.

This study investigated on the nutritional components and physiological activity of four wild vegetables namely Salvia plebeia R. Br., Angelica acutiloba, Gynura procumbens and Saururus chinensis Baill for the development of representative wild vegetables in Chungbuk. Salvia plebeia possessed the highest radical scavenging activity and beta-carotene, but exhibited the lowest α-glucosidase inhibitory activity compared to the other three vegetables. Angelica acutiloba showed high crude protein content and α-glucosidase inhibitory activity, but contained low total polyphenol content, radical scavenging ability and beta-carotene compared to the other three vegetables. Gynura procumbens showed high mineral content, beta-carotene, vitamin K1 content and α-glucosidase inhibitory activity, but showed the lowest total polyphenol content and radical scavenging ability compared to the other three vegetables. Saururus chinensis showed high crude fiber content and total polyphenol content, but contained the lowest mineral and vitamin K1 content. To conclude, it is suggested to use Salvia plebeia or Saururus chinensis as antioxidant food materials and Angelica acutiloba and Gynura procumbens as food materials and sources of α-glucosidase inhibitors. In particular, it is believed that Saururus chinensis, which possessed high content of crude fiber, is suitable for low-calorie food materials such as diet products.

A survey on the understanding of environment-friendly certification system was conducted for certified operators. The survey included the necessity of certification system, difficulties in producing certified products, and general evaluation of the current certification system. Certified operators were generally satisfied with the certification system in terms of the certification standards, the public subsidy programs, and the farm management costs. Individuals with parallel production farms were relatively less satisfied than the group with full-time organic farmers. Analysis using the ranking probit model indicated that the longer the certification experience, the more highly aware the need for the certification system was. Our results indicated that policy strategies are needed to enlarge the marketability of environment-friendly agricultural products since economic factors of organic products were the most important factor for maintaining and expanding certification in overseas as well as in Korea. It seems to be necessary to implement economic triggers for certified operators to continue their certification programs by promoting the transition period certification for individual farms in parallel with conventional agriculture. Analysis of the variables correlated with the expansion of environment-friendly agriculture by the logit model implied that certified operators with the younger age and higher annual incomes were more likely to expand environment-friendly agriculture. Therefore, it might also be important to provide financial support and incentives for new entry farmers to participate in environment-friendly agriculture and establish a system to share the know-how of successful certified organic farmers.

This survey was conducted to secure a basic data for the effective training programs that might be an essential part of any successful mechanization of agriculture in Korea. Chung Nam provincial training center and 17 guidance offices with farm machinery training centers which were thought to be a medium level on their scale in whole country were selected in the survey on its training accomplishments, stafts, facilities, schedule and number of trainees at one time or in a class. The results and recommendations from this survey were as follows; To enhance the effect of farm machinery training, it was absolutely necessary for city or county training center to complement its facilities and equipments. It might be desirable that instructors of each training center should be the one educated or highly trained in the institution of farm machinery, and that the number of technical assistants should be increased and their present part time working condition should be changed to full-time status. It was recommended that training for farmers should be scheduled during off-season so that farmers could participate in the training couses, and that the number of trainees in a class should be reduced to about 10 trainees, which was approximately a fourth of the present situation.

BACKGROUND: Although the calcined oyster shell can be used as a calcium-rich adsorbent for phosphate removal, information about it is limited. The purpose of this study was to evaluate the phosphate adsorption characteristics and its mechanism using calcined oyster shells. METHODS AND RESULTS: In this study, calcined oyster shell (C-OS600) was prepared by calcining oyster shells (P-OS) at 600℃ for 20 min. Phosphate adsorption by C-OS600 was performed under various environmental conditions. Phosphate adsorption by C-OS600 occurred rapidly at the beginning of the reaction, and the time to reach equilibrium was less than 1 h. The optimal isotherm and kinetic models for predicting the adsorption of phosphate by C-OS600 were the Langmuir isotherm and pseudo-second order kinetic model, respectively, and the maximum adsorption capacity derived from the Langmuir isotherm was 68.0 mg/g. The adsorption properties of phosphate by C-OS600 were dominantly influenced by the initial pH and C-OS600 dose. In addition, SEM-EDS and FTIR analysis clearly showed a difference in C-OS600 before and after phosphate adsorption, which proved that phosphate was adsorbed on the surface of C-OS600. CONCLUSION: Overall, the calcined oyster shell can be considered as an useful and effective adsorbent to treat wastewater containing phosphate.
