The "leading farms" or "superior management farms" were relatively capable to overcome various limitations in rapidly changing agricultural environment and economic conditions, and quick to adopt agricultural management innovations and accomplish more compared to the other farms in shorter durations. The farmers from these "leading farms" were innovative and dynamic, and endowed with potentials to be the core leaders in rural society. Their adaptability created a difference and worthy of emulations. The purpose of this research was to propose a policy to develop, promote and sustain these leading farms. There were some problems in communication structures and in implementing agricultural policies for upbringing leading farmers. In coordination with the Ministry of Agriculture and Forestry(MAF) and Rural Development Administration (RDA), this article attempted to come up with workable strategies to solve these problems affecting the leading farms.

The study aims at analysing the practical effects of "blended learning system" and participatory research methodology. The business programs are running by RDA. Even though many leading farms have been tried on binding technology and agribusiness, however business of farms in Korea are still in the beginning stage. The business program for leading farms of RDA is not only education program but also participatory research program. This program consist of on-line and off line, seminar and business homework etc. The main results of this paper are as follows: 1) to make organization of farms to accomplish business goals 2) to find out solution for urgent problems and subjects of farm management 3) to construct system for leading farms and on-line communities 4) to practice profitable business model for leading farms. Farms needs are not only technology transference, but business model for success of farm management.

This study analyzed the management efficiency of jujube, bitter persimmon, and chestnut farms using data envelopment analysis (DEA). And this study analyzed causes affecting management inefficiency of those farms using the two-step method. The main findings are as follows. First, as self and employment labor costs are increased, it is important to reduce labor costs which account for 60~70% of the total production cost. Second, efforts to improve management efficiency are needed as overall efficiency of farms were decreased. Third, a pesticide cost per 10a representing a level of pesticide had a negative effect or did not have a statistically significant effect on the management efficiency. This implies that expanding environment-friendly production by reducing pesticides is effective for improving the management efficiency. Fourth, as leading farms were more efficient than general farms, technology dissemination and education through leading farms are important for improving efficiency, and efforts are needed to promote exchange between leading and general farms.

The purposes of this study were (1) to highlight the importance of farm management (2) to develop a profitable farm management system through the combination of agricultural techniques and business competencies (3) to shift management attitudes and habits of the program participants from being passive and dependent toward being proactive and self-disciplined (4) to help cultivate one's own life through self-consciousness participation in educational activities and lectures of celebrities. This research was conducted involving 30 farms that participated in the business program. The program imparted knowledge on vision, marketing, business skills, and management strategies such as cross strengths, weaknesses, opportunities, threats (swot) analysis, product life cycle (plc), the 4p(product, price, place, promotion) of marketing, etc. The study recommends: (1) to encourage farms to enhance their business competencies; (2) to find out solutions for urgent management problems (3) to construct a system for leading farms (www.lfcenter.com) and on-line communities and (4) to implement a profitable business model for leading farms. It was noted that the farms were eager to participate in such business programs. In the future, this kind of program should be promoted in other areas so that more farms could enhance their business competencies.

The purpose of this study is to empirically analyze factors that influence farm managers' intentions to use an agricultural farm management information systems. It focused on "LFcenter System," a leading information system operated by the Rural Development Administration for farm management. Participants of this study are classified into two groups: a group of leading farm managers and a group fo regular farm managers. A total of 192 survey samples on users' intentions are collected; 85 samples from leading farm managers and 107 from regular farm managers. The theoretical background of this study is developed based on Theory of Reasoned Action(TRA), Technology Acceptance Model(TAM), Diffusion of Innovation(DOI), Social Cognitive Theory(SCT), and Theory of Planned Behavior(TPB). Partial Least Squares(PLS) method is used to test a proposed Structural Equation Model(SEM), including nine hypotheses. The differences between two groups are investigated using Smith-Satterthwait test. The findings from this study are: First of all, in terms of average comparison of most variables used in this study, a group of leading farm managers shows higher value that the other group in most cases. Second, hypothesis tests how that "subjective norms", "goal to study", "perceived usefulness", "perceived enjoyment", and "intention to use" significantly influence the intention to use an agricultural management information system in the group of leading farm managers. However, "subjective norms", "goal to study", "perceived ease of use", "perceived usefulness", "perceived enjoyment", and "intention to use" turned out to significantly influence the intention to use an agricultural management information system in the group of regular farms managers. Based on the results of Smith-Satterthwait test, compared with a group of leading farms managers, the impact of "goal to study" on "intention to use" is significantly stronger. On the other hand, in the group of leading farms managers, "perceived usefulness" and "perceived enjoyment" turned out to be main drivers of "intention to use."

Avian pathogenic E. coli (APEC) causes severe economic losses in the poultry farms, due to systemic infections leading to lethal colisepticemia. It causes a variety of diseases from air sac infection to systemic spread leading to septicemia. Secondary infection contains opportunistic infections due to immunosuppression disease. Collibacillosis causes the great problems in the poultry industry in Korea. Thus, it is necessary to identify and classify the characteristics of E. coli isolate of chicken origin to confirm the diversity of symptoms and whether they are transmitted among the farms. Fragment analysis is identify the difference in the number of Variable-Number Tandem-Repeats (VNTRs) for genotyping. VNTRs have repeating structure (Microsatellite, Short tandem repeats; STR, Simple sequence repeats; SSR) in the chromosome. This region can be used as a genetic marker because of its high mutation rate. And various lengths of the amplified DNA fragment cause the difference in the number of repetition of the DNA specific site. The number of repetition sequences indicates the separated size of fragments, so the each fragments can be distinguished by specific samples. The results of the sample show that there is no difference in six microsatellite loci (yjiD, aidB, molR_1, ftsZ, b1668, yibA). There are differences among the farms in relation of the number of repetitions of other six microsatellite loci (ycgW, yaiN, yiaB, mhpR, b0829, caiF). Four (ycgW, yiaB, b0829, caiF) of these six microsatellite loci show statistically significant differences (P<0.05). It means that the analysis using four microsatellite loci including ycgW, yiaB, b0829, and caiF can confirm among the farms. Five E. coli samples in one farm have same SSR repetition at all markers. But, there are significant differences from other farms at Four (ycgW, yiaB, b0829, caiF) microsatellite loci. These results emphasize again that the four microsatellite loci makes a difference in the amplified DNA fragments, enabling it to be used for E. coli genotyping.

Background: Since 2003, the H5 highly pathogenic avian influenza (HPAI) subtype has caused massive economic losses in the poultry industry in South Korea. The role of inland water bodies in avian influenza (AI) outbreaks has not been investigated. Identifying water bodies that facilitate risk pathways leading to the incursion of the HPAI virus (HPAIV) into poultry farms is essential for implementing specific precautionary measures to prevent viral transmission. Objectives: This matched case-control study (1:4) examined whether inland waters were associated with a higher risk of AI outbreaks in the neighboring poultry farms. Methods: Rivers, irrigation canals, lakes, and ponds were considered inland water bodies. The cases and controls were chosen based on the matching criteria. The nearest possible farms located within a radius of 3 km of the case farms were chosen as the control farms. The poultry farms were selected randomly, and two HPAI epidemics (H5N8 [2014-2016] and H5N6 [2016-2017]) were studied. Conditional logistic regression analysis was applied. Results: Statistical analysis revealed that inland waters near poultry farms were significant risk factors for AI outbreaks. The study speculated that freely wandering wild waterfowl and small animals contaminate areas surrounding poultry farms. Conclusions: Pet birds and animals raised alongside poultry birds on farm premises may wander easily to nearby waters, potentially increasing the risk of AI infection in poultry farms. Mechanical transmission of the AI virus occurs when poultry farm workers or visitors come into contact with infected water bodies or their surroundings. To prevent AI outbreaks in the future, poultry farms should adopt strict precautions to avoid contact with nearby water bodies and their surroundings.

In March 2015, the milk quota system in Europe that had lasted for more than 30 years was abolished to improve the competitiveness of the European dairy sector in the international market. Despite an increase in the consumption of dairy products in Europe, the milk price is expected to stabilize in the next decade after a decrease between 2015 and 2016. This stabilization of prices will be caused by a significant increase in production, with the proportion exceeding domestic demand to be exported. In the international market, the price of milk will reduce in the next decade, leading to a restructuring of the milk sector with a lower number of farms, but with higher production and efficiency. Mountain farms will follow the same trend, although these farms play an important social role by providing ecosystem services such as maintaining cultural services, reducing greenhouse gas emissions, promoting soil stability, and improving the aesthetic value of the landscape. Nevertheless, they remain at a disadvantage compared with lowland farms. To prevent the loss of mountain farms, there is thus a need to valorize the ecosystem services that they provide and promote the processing of milk into certified products of high quality.

Arthropod-borne viruses (Arboviruses) are transmitted by arthropods such as Culicoides biting midges and cause abortion, stillbirth, and congenital malformation in ruminants, apparently leading to economic losses to farmers. To monitor the distribution of Culicoides and to determine their relationship with different environmental conditions (temperature, humidity, wind speed, and altitude of the farms) on 5 cattle farms, Culicoides were collected during summer season (May-September) in 2016 and 2017, and analyzed for identification of species and detection of arboviruses. About 35% of the Culicoides were collected in July and the collection rate increased with increase in temperature and humidity. The higher altitude where the farms were located, the more Culicoides were collected on inside than outside. In antigen test of Culicoides against 5 arboviruses, only Chuzan virus (CHUV) (2.63%) was detected in 2016. The Akabane virus (AKAV), CHUV, Ibaraki virus and Bovine ephemeral fever virus (BEFV) had a positive rate of less than 1.8% in 2017. In antigen test of bovine whole blood, AKAV (12.96%) and BEFV (0.96%) were positive in only one of the farms. As a result of serum neutralization test, antibodies against AKAV were generally measured in all the farms. These results suggest that vaccination before the season in which the Culicoides are active is probably best to prevent arbovirus infections.

농산물 수출과 관련된 분석은 자료의 부족 때문에 피상적인 분석 이상 나아가기가 쉽지 않았다. 분석을 하더라도 간접적인 자료만을 활용한 분석이어서 해석상의 한계가 많았다. 이 연구는 수출업체의 실제 수출실적 자료를 분석하였다. 분석 결과, 농가의 평균수취율은 72.3%로 나타났지만 거리에 따른 운송비 때문에 지역에 따라 차이가 났다. 수출농가의 소득률은 전반적으로 국내에 출하하는 농가에 비해 높게 나타났으며 수출비중이 높을수록 소득률은 상승하는 것으로 나타났다. 또한, 수출단가와 비용을 분석한 결과, 정부와 지자체의 보조금이 없을 경우 수출업체의 채산성은 크게 악화되는 것으로 나타났다.
