The technology of direct-seeding in rice cultivation is an innovation mainly induced by factors in market economy and is rapidly diffused among individual farmhouses. Because the effect of technology can be affected by many factors under various farming circumstances, the impact and stability of the direct-seeding technology compared with transplanting was analyzed under various topographical regions. Yield in direct-seeding was higher in plains, although the farm size producing higher yield was quite different depending on the topographical regions. In the direct-seeding cultivation of rice, man-labor hours was reduced by about 38 percent and the reduction rate showed little difference among topographical regions. Fertilizer was used about 11 percent more but the increase rate varied from 3 to 17 percent depending on regions with higher rates in plains. Application of agricultural chemicals was also increased about 9 percent in direct-seeding, but the increase rate was as high as 12 percent in suburbs. More fertilizer and agricultural chemicals were used in direct-seeding cultivation by farmhouses implementing both direct-seeding and transplanting than by those implementing direct-seeding only. Use of more fertilizers and agricultural chemicals in direct-seeding in all regions may indicate its technical instability. Major problems causing the technical instability of direct-seeding cultivation should be solved by comprehensive research considering various farming circumstances such as topographical features rather than just a top-down style research and extension.

Objective: This study investigated the effects of feeding anthocyanin-rich black cane treated with ferrous sulfate and molasses on animal performance, rumen fermentation, microbial composition, blood biochemical indices, and carcass characteristics in meat goats. Methods: Thirty-two Thai-native×Anglo-Nubian crossbred male goats (14.47±2.3 kg) were divided equally into two groups (n = 16) to investigate the effect of feeding diet containing 50% untreated anthocyanin-rich black cane silage (BS) vs diet containing anthocyaninrich black cane silage treated with 0.03% ferrous sulfate and 4% molasses (TBS) on average daily gain (ADG) and dry matter intake (DMI). At the end of 90 d feeding trial, the goats were slaughtered to determine blood biochemical indices, rumen fermentation, microbial composition, and carcass characteristics differences between the two dietary groups. Results: Goats fed the TBS diet had greater ADG and ADG to DMI ratio (p<0.05). TBS diet did not affect rumen fluid pH; however, goats in the TBS group had lower rumen ammonia N levels (p<0.05) and higher total volatile fatty acid concentrations (p<0.05). Goats in the TBS group had a higher (p<0.05) concentration of Ruminococcus albus but a lower (p<0.05) concentration of methanogenic bacteria. The TBS diet also resulted in lower (p<0.05) thiobarbituric acid-reactive substances concentration but higher (p<0.05) total antioxidant capacity, superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase concentrations in blood plasma, while having no effect on plasma protein, glucose, lipid, immunoglobin G, alanine transaminase, and aspartate aminotransferase. Meat from goats fed the TBS diet contained more intramuscular fat (p<0.05) and was more tender (p<0.05). Conclusion: In comparison to goats fed a diet containing 50% untreated anthocyanin-rich black cane silage, feeding a diet containing 50% anthocyanin-rich black cane silage treated with 0.03% ferrous sulfate and 4% molasses improved rumen fermentation and reduced oxidative stress, resulting in higher growth and more tender meat.
As increasing trade through the world, especially in food, asymmetry of information can make the trade shrink. With the industrial development, Korea's agriculture had shrunk dramatically. By the result of the nation's industrial restructuring, over than 3/4 of Korea food consumption comes from abroad. And China is an important source of agricultural product to Korea. Increasing family income and increasing importing food consumption, Korean consumers have been interested in food safety. Especially. after experiencing several cases like struggle for safety of GMO food, poultry influenza, lead contained Chinese fish import, mad cow disease, cheating origin, etc. Obviously, those unreliable cases will hinder the increase of world free trade as well as the trust of two countries. Furthermore, distrust will be a cause of adverse selection. So, it need to find a way to solve the distrust which caused by asymmetry of information. And automatic identification procedures can help mitigate asymmetry of information in trade. And it will make Korean consumers can avoid adverse selection. This paper suggests adoption of Auto ID to encourage agricultural trade between Korea and China.
The Joseon Dynasty lasted for 618 years, from 1392 to 1910, and is regarded as one of the development periods of Korea in various areas, including politics, culture, economy, and society. During this period, the government undertook various measures to try to change the state of the economy and generally transform people's living standards. These were some of the strategies founded on Confucianism, which focused on the right way to govern and manage the economy to attain prosperity for the society. The present study explores government development strategies for improving the economy in Joseon Dynasty period using comprehensive literature analysis via Kci, Scopus, Web of Science databases. Indeed, agricultural transformations during the Joseon dynasty clearly show that knowledge and innovation were critical for encouraging agricultural growth. Therefore, today's South Korean government can implement technological advancement and research to improve its agricultural value chain and food security. Many farmers lack knowledge about improved methods of practicing agriculture or have inadequate capital to invest in research and development; these issues can be dealt with by the relevant government agencies putting in place necessary policies and creating awareness through educational programs and articles.

Agriculture has always been the foundation of Vietnam's economy, accounting for a significant portion of GDP. However, like many traditional industries, Vietnamese agriculture faces many challenges, from inefficient supply chains to unpredictable weather developments. In recent years, Vietnam's agricultural sector has been looking for ways to improve productivity and efficiency by applying modern technology. Among these technologies, artificial intelligence (AI) has emerged as a potential solution to address the challenges farmers and other stakeholders face in the agricultural supply chain. AI can analyze large amounts of data, optimize resource allocation, and predict market trends, which can significantly improve decision-making in agriculture. However, despite the promising prospects of AI in agriculture, there are still challenges to the widespread application of AI in Vietnam. These include the need for more awareness, technical expertise, and Infrastructure to support AI implementation. In this study, we analyze the current state of AI applications in Vietnam's agricultural supply chain, identify key challenges, and propose strategies to facilitate the integration of AI technology in agriculture supply chains in Vietnam in the digital age.
This study postulates a study model to examine the effect on the local economy revitalization of a selection of local resources, the local innovation capability strengthening, the establishment of promotion system and the creation of revenues for the participant groups of the local industry promotion project. To accomplish study purposes, 169 response samples from 85 project groups which drive the local industry promotion project were verified using SPSS 12.0 and AMOS 5.0. The results showed that firstly, the selection of local resources had a significant effect on the local innovation capability strengthening. Secondly, the local innovation capability strengthening had a significant effect on the establishment of promotion system. Thirdly, the establishment of promotion system had a significant effect on the creation of revenues. Fourthly, the selection of local resources didn't have an effect on the revitalization of local economy. Fifthly, both the local innovation capability strengthening and the establishment of promotion system didn't have an effect on the revitalization of local economy. Sixthly, the creation of revenues had a significant effect on the revitalization of local economy. According to the verifications of study model, the revitalization of local economy is achieved by inducing creation of revenues through the local innovation capability strengthening and the establishment of promotion system after the selection of local resources. From these results, this study presents suggestions, limits of study and directions in the future study.
Fundamental advances in the biotechnologies are exerting a profound influence on the health care, agricultural, industrial chemical, environmental, and other industrial fields. Korean government are now more and more realizing the importance of biotechnology as a main technology for the 21st century. But any technical progress is largely the result of a complex set of relationships among the firms, institutions and others involved in development. So understanding the complexity is very important to make promoting strategies and it is even critical in the field of biotechnology. The reason is that commercialization of research results in biotechnology is strongly related with the national science bases provided by academic and public institutes. And its applicable industrial sectors are very diverse. So it is very important to make a effective collaboration system among many R&D related agents. This article discusses and compares both USA and Japanese framework of national innovation systems in the field of biotechnology. The American Innovation system encourages basic research in the biological sciences, and fosters the creation of small venture firms that focus on the development of novel products. America's peculiar incentive structure, derived from its research and educational system, financial system, and regulatory environment has driven USA labs and firms to the forefront of many biotechnology fields. The Japanese institutional environment in contrast, supported the strategy of building production expertise. Firms were urged to use the new techniques as a way of leapfrogging into a second generation of bio-products, in that cost and production advantages count. But the strategy was not effective as expected and Japanese firms have remained competent but not prominent rivals. The differing situations in USA and Japan with regard to biotechnology have many suggestions for our bioindustry. In the conclusion of this article, we translate USA and Japan's experiences to some suggestions which guide for promoting Korea's biotechnology R&D and commercialization activities.
The projects of agricultural R&D investments have been evaluated largely on the basis of efficiency better than equity although both criteria are equally critical in that major fund source of agricultural R&D investments is public budget. In this study, I focus on equity aspects by identifying the heterogeneous impacts of public knowledge created by R&D on farm efficiencies by farm income levels using bias-corrected DEA and quantile regression with panel data. The findings indicate that entire farms haven't been likely to be benefited evenly from public knowledge stock created by agricultural R&D, in particular high income farms can have enjoyed relatively more benefits of its in terms of efficiency gain. Those can imply agricultural R&D have functioned in the way analogue to digressive subsidies. In addition, the heterogeneous technological needs different among income level farms turns out to be main underlying factors affecting such the skewed benefit distribution of agricultural R&D over different income level farms.
Recently, agricultural lands decrease sharply, which was caused by urbanization, land consolidation, road construction, and innovation city construction, etc. In particular, Goyang, Chenan and Wonju city were had severe land use change. Therefore, we analyzed changes of land use, soil properties, and soil information in order to provide the basic soil information and soil management practice in these cities. The results are summarized as follows. The area of crop cultivated land in Korea (2011) was reduced to 17.3ha compared to ones from the previous year (2009). The paddy field decreased by 24.2 ha but, upland field increased by 7.0 ha. The reasons for the reduction of the paddy field were converting paddy field to upland (20.7 ha) > public facilities (3.2) ${\geq}$ building (3.2) > idle land (1.3) > and others (0.9). Other reasons for reduction in the upland field were switching upland to paddy field, (20.7 ha) > land developed (4.5) > and restoration (0.3) respectively. The main reason of converting paddy field to upland was changing from rice to more profitable upland or greenhouse crops. The cropland area (paddy fields, upland, orchard) of Goyang, Cheonan, and Wonju city were reduced to 1,466 ha, 9,708 ha and 6,980 ha respectively. The ratio of cropland area in each city was reduced by 45~25% dramatically compared to upland soil survey project in Korea (1995~1999). These data were compared with MiFAFF statistics data to use for land use cover map of Ministry of environment. But they were differences significantly. Therefore, intensive investigation should be advised throughout the utilization plan. The paddy fields located in small valley in Wonju city were changed into upland or orchard. The drainage classes of soil have been deteriorated because the flows of water were intercepted by road construction and other disturbance to water flows. In particular, paddy fields have been changed to not only upland, orchard, greenhouse cultivation but also to fallow and soil dressing on paddy in Wonju city. The soil suitability classes of paddy field in Wonju innovation city were the 3rd grade for 70.8% of the area and the 4th grade for 29.2%. The soil suitability classes of upland was the 4th grade for 88.7% of the area. Fortunately, good soil suitability classes were not belong to innovation city in Wonju. So, the good farm land should be conserved and revise the related law.
