  • 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.

  • This study is first aimed at identifying the possibility of labour saving and production cost decreasing in rice production with respect to seed broad casting technology. Comparison of labour inputs and production costs of rice in-between USA and Korea and recommendation of policy guidelines for the continous rice cultivation are the second objective of this study. Under the WTO system, rice enterprice is the most vulnerable crop in the sense of labour productivity and price competitiveness in the international market. How to adapt labour saving technology and how to decrease production costs are the most imminent problems to be solved in rice production. To achieve the objectives, survey on nine rice enterprice farms were made in Daeho tidal farmland with respect to the size of farm, labour inputs, productivity, farm mechanization and farm land base development. The existing data on labour saving technology by seed broadcasting which had surveyed by Rural Development Administration were collected to compare the surveyed data from Daeho tidal farm land The study results and policy recommendation are summarized as follows; 1. Labour requirements per 10a for rice enterprise farms with seed broadcasting and with transplanting were estimated 11.4 and 18.5hours respectively. 'This above labour inputs were equivalent to 1/3-1/5 of the national average labour inputs of 53.6 hours which were included transplanting and harvesting by machinery. Considering the labour requirement of 1.7 hours per 10a for the USA rice production, Korea rice culture has possibility to decrease labour demand upto USA level of labour inputs. 2. Production cost of rice in Korea were estimated US$4,181 per ha which were higher than that of USA by 3.00 times and production costs per ton were shown as US$313 for USA rice and US$1,018 for Korean rice. 3. Land productivity of rice per 10a in America was reached to 4,325kg and the counterpart of Korea was about 4,181kg in recent year. In the sense of land productivity, both yields of rice were comparable. 4. The price of japonica type rice similar to Korean traditional rice in international market in 1994 was f.o.b US$466 per ton which was equivalent to import parity price of US$830 per ton in domestic market. The price of rice purchased by Korean G't and received by farmers were amounted to US$ 2,013 and US$ 1,663 respectively in the same year. Domestic prices mentioned above were higher than the import parity price as US$830 by 2.0-2.4 times. 5. American rice production competitive to Korean rice was equivalent to 17,012 thousand tons, 1.28% of the world production of rice in 1991 and consumption of rice in America was amounted to 2,633 thousand tons. Exportable quantity of USA rice were estimated as 4,379 thousand tons of which 52.3%, 2,300 thousand tons, were exported indeed in the same year. 6. The quantity of Korean rice produced in 1991 was estimated 1.00% of the world production. The world amount of rice exported in 1991 was reached to 2.45% of the world production of which 34.2% was occupied by USA The remaining quantities of world exported rice were dominated by Tiland, Pakistan and Vietnam where produced indica variety. 7. Under the given technology, labour inputs per 10a for rice production could be possible to save by 70% of the national average labour requirement of 53.6 hours through implmenting complete farm mechanization with land consolidation and on-farm development and improvement of fanning practices like seedbroad casting txchnology etc. On the other hand, prduction costs of rice could be decreased by 10% rather than 49% as target indicated in the Rural Development Counter Measures of Korean Government in 1994 owing to increasing farm mechanization cost and interest on land service with high price. Accordingly production cost of rice per kg could be decreased only by 10% of the 1994 production cost. 8. Rice policy of Korean government in the future should take into account the labour saving technology to solve labour shortage in rural area and to enhance off-farm incomes by creating job opportunities in agro-industrial zones and special production area. On account of the staple food and main energy source for people's health, rice production even encountered vulnerable economic settings should be continued without price distortion policies and discouraging farmer's intention to cultivate rice by importing institutionally the direct income subsidy system.

  • In general, cloned pigs have been produced using the somatic cell nuclear transfer (SCNT) technique with various types of somatic cells; however, the SCNT technique has disadvantages not only in its low efficiency but also in the development of abnormal clones. This study aimed to compare early embryonic development and quality of SCNT embryos with those of induced pluripotent stem cells (iPSCs) NT embryos (iPSC-NTs). Ear fibroblast cells were used as donor cells and iPSCs were generated from these cells by lentiviral transduction with human six factors (Oct4, Sox2, c-Myc, Nanog, Klf4 and Lin28). Blastocyst formation rate in iPSC-NT (23/258, 8.9%) was significantly lower than that in SCNT (46/175, 26.3%; p < 0.05). Total cell number in blastocysts was similar between two groups, but blastocysts in iPSC-NT had a lower number of apoptotic cells than in SCNT (2.0 ± 0.6 vs. 9.8 ± 2.9, p < 0.05). Quantitative PCR data showed that apoptosis-related genes (bax, caspase-3, and caspase-9) were highly expressed in SCNT than iPSC-NT (p < 0.05). Although an early development rate was low in iPSC-NT, the quality of cloned embryos from porcine iPSC was higher than that of embryos from somatic cells. Therefore, porcine iPSCs could be used as a preferable cell source to create a clone or transgenic animals by using the NT technique.

  • When the marcher visited Korea in fall 1994, he was shocked to see high rise apartment buildings around the capitol region including Seoul and Suwon, resulting from rising demand of housing because of urban migration followed by second and third industrial development. After 6 years in March 2000, the researcher witnessed more apartment buildings and vinyl house complexes, one of the evidences of continued economic progress in Korea. Korea had to receive the rescue finance from International Monetary Fund (IMF) because of financial crisis in 1997. However, the sign of recovery was seen in a year, and the growth rate of Gross Domestic Products (GDP) in 1999 recorded as high as 10.7 percent. During this period, the Korean government has been working on restructuring of banks, enterprises, labour and public sectors. The major directions of government were; localization, reducing administrative manpower, limiting agricultural budgets, privatization of public enterprises, integration of agricultural organization, and easing of various regulations. Thus, the power of central government shifted to local government resulting in a power increase for city mayors and county chiefs. Agricultural extension services was one of targets of government restructuring, transferred to local governments from central government. At the same time, the number of extension offices was reduced by 64 percent, extension personnel reduced by 24 percent, and extension budgets reduced. During the process of restructuring, the basic direction of extension services was set by central Rural Development Administration Personnel management, technology development and supports were transferred to provincial Rural Development Administrations, and operational responsibilities transferred to city/county governments. Agricultural extension services at the local levels changed the name to Agricultural Technology Extension Center, established under jurisdiction of city mayor or county chief. The function of technology development works were added, at the same time reducing the number of educators for agriculture and rural life. As a result of observations of rural areas and agricultural extension services at various levels, functional responsibilities of extension were not well recognized throughout the central, provincial, and local levels. Central agricultural extension services should be more concerned about effective rural development by monitoring provincial and local level extension activities more throughly. At county level extension services, it may be desirable to add a research function to reflect local agricultural technological needs. Sometimes, adding administrative tasks for extension educators may be helpful far farmers. However, tasks such as inspection and investigation should be avoided, since it may hinder the effectiveness of extension educational activities. It appeared that major contents of the agricultural extension service in Korea were focused on saving agricultural materials, developing new agricultural technology, enhancing agricultural export, increasing production and establishing market oriented farming. However these kinds of efforts may lead to non-sustainable agriculture. It would be better to put more emphasis on sustainable agriculture in the future. Agricultural extension methods in Korea may be better classified into two approaches or functions; consultation function for advanced farmers and technology transfer or educational function for small farmers. Advanced farmers were more interested in technology and management information, while small farmers were more concerned about information for farm management directions and timely diffusion of agricultural technology information. Agricultural extension service should put more emphasis on small farmer groups and active participation of farmers in these groups. Providing information and moderate advice in selecting alternatives should be the major activities for consultation for advanced farmers, while problem solving processes may be the major educational function for small farmers. Systems such as internet and e-mail should be utilized for functions of information exchange. These activities may not be an easy task for decreased numbers of extension educators along with increased administrative tasks. It may be difficult to practice a one-to-one approach However group guidance may improve the task to a certain degree.

  • This study aims to suggest the necessary political implications for the introduction of green tourism in "Mountain Village Project" through the survey of local residents on the recognition of rural and mountain villages about the Village Development Projects. Direct survey using a structured questionnaire was executed to each local resident in different types of rural tourism villages such as the Mountain development village, the Green agricultural village, the Rural theme village, and mixed type of village between them. It was revealed that local residents in the Mountain development village had a positive reaction to the Project, whereas those in mixed type of village did not notice highly the change by the Project. Residents in the Mountain development village highly satisfied with the Project as improved income sources. In addition, it was shown that local residents recognised the necessity of social education and they highly wanted to participate in it. Residents in the Green agricultural village also wanted to put an effort to introduce an activity-based program for village development.

  • The last few nears have seen significantly increased interest in organic food. Organic food is still a small but growing part of the food industry with an identity defined and protected by law. Its existence provides an element of consumer choice. To obtain consumer confidence and, product credibility and transparency in the organic market, organic legislation and certification is needed, To facilitate export of organic products, harmonization of the organic legislation is favoured. The IFOAM accreditation programme has already achieved very much in this respect. Several national regulation, such as the NOP(USA) and EC2092/91(European Union) have already complied with the IFOAM basic standards. But in many countries there is still a lack of national legislation on organic agriculture. Because of the fast globalisation, organic agriculture is facing major challenges for international trade, so it is very important to consider the future development and certification of organic produce in all countries.

  • The Republic of Korea (ROK) has had a successful experience in greening its land because of strong state policy and public participation. This paper aims to analyze the interest positions, participation, and accountability of multiple actors in the process of greening movements in the ROK. These movements were divided into two phases: forest rehabilitation (1973-1997) and urban greening (1998-2017). During the first phase, farmers caused deforestation by slash-and-burn farming and illegal logging, and governmental agencies acted as helpers controlled the farmers' deforestation activities. During the second phase, government agencies and enterprises caused deforestation with urban development projects, including construction of housings and roads. Multiple actors including citizens, NGOs, and enterprises helped urban greening through campaigns, donations, and monitoring. As a result, managing interest positions is significant to motivate multiple actors to participate in the greening movement. Participation with clear accountability is meaningful for successful greening. Therefore interest-based participation requiring accountability contributes to greening. This phenomenon indicates interconnection for interest positions, participation and accountability should be considered in designing greening policies.

  • California's heartland, the Great Central Valley, is one of the most productive agricultural regions in the world. However for many years the valley has been struggling with a broad range of social, economic, and environmental challenges. Some significant concerns include water resources, air pollution, poverty rates, housing issues, etc. Another strike against the valley is the relative reluctance to embrace widespread sustainable building practices. This paper discusses the long-term and profound impact of the built environment has on the aforementioned socioeconomic and environmental issues facing the valley. It reviews exemplary practices in other states and regions regarding policy-making and regulation in the building industry as well as sustainable community development. The paper further explores viable options specifically for the Fresno metropolitan area (the largest in the Central Valley) to combat its unique multifaceted challenges.
