Butyric acid (C4 carboxylic acid) is used as an important compound in food, pharmaceutical, and chemical industries. Currently, butyric acid is mainly produced at the industrial scale through the petrochemical processes. Bio-based butyric acid has also gained attention, because the consumer prefers the food and pharmaceutical ingredients that are produced through fermentation. Clostridia is one of the well-known butyric acid producers, and massively engineered for enhanced production of butyric acid. In this paper, we reviewed the metabolic pathway of clostridia, especially Clostridium acetobutylicum and Clostridium tyrobutyricum, and summarized the metabolic engineering strategies of the strains for enhanced production of butyric acid.

The Extension Program accountability will continue to be an influential force to develop agriculture and rural area. As we incorporate new approaches into our service program and respond to new domains of knowledge, we must also consider how our assessment strategies may need to change in order to meet local and other external standards. The main purpose of the study was to be what the best way of Extension Service is set farmers' educational needs met and to be what kind of methodologies and role of Extension system should provide for their faced problem solving effectively. The major results of the study on Farmers' needs toward Korean Extension Services are summarized as follows. First, it is observed that, when the farmers' perceptions were analyzed, the most ranked by the farmers' needs was "having nice extension workers to get advice and solve their problems on the farm in all at once." Farmers had especially more positive attitudes in the categories of interest and careers in ag-technology. To do services level up, the headquarter of Rural Development of Administration must be work with local branches to effectively deliver their missions and educational objectives to target crops and farmers group. And farmers were strongly needed "a specialized service team will be organized" to work closely with operating services for ag-products processing, packing and marketing. The recommendations were made by: farmers' needs should be identified and announced by computer networking development to solve their problems faster. Also, provincial and county level service members should have a chance to working at research institute or related work places with their incentives, which system will be easer to meet farmers' needs and deal with their problems so that the systematic approaches should be managed and recorded their educational attendings, education contents and even their farming corporations. Finally, Agricultural Extension Service should be met to general ag-technology literacy and be balanced with knowledge of other industries and be competitive service with better values in non-agricultural sectors.

Brucellosis, a bacterial zoonoses caused by the genus Brucella is responsible for abortion and infertility in cow. Brucellosis is causing economic loss in dairy industries and prevalent worldwide including Bangladesh but limited studies are devoted to determine the prevalence and its association with reproductive factors of dairy cows in Bangladesh. Therefore, the present study was conducted to determine the seroprevalence of brucellosis in dairy cattle using screening test Rose Bengal test (RBT) and the positive sera were further confirmed by indirect- ELISA. For this purpose, a total of 400 serum samples from dairy cows with history of abortion and various reproductive disorders were collected from the Kurigram district of Bangladesh for the detection of Brucella antibody. The overall prevalence of brucellosis in dairy cattle was 2.25%. Brucellosis in cases of abortion and repeat breeding was 8.3% and 2.8%, respectively. The results shows higher prevalence of brucellosis in cases of abortion followed by repeat breeding, while there was no seropositive cases from other reproductive disorders. Age-wise sero-prevalence was found 3.0% in 2~3 years age group and 2.0% in 4~8 years age group. The prevalence of brucellosis in indigenous and cross-bred cattle was 3.6% and 1.7%, respectively. All the animals detected positive to brucellosis by RBT were not found to be positive by i-ELISA. However, the RBT might be a suitable screening test for the diagnosis of Brucella infection in field condition in Bangladesh. These data will help to develop effective disease prevention strategies.

Korean agricultural industry has weakened as demand for domestic agricultural products has declined due to accelerating market liberalization, aging and shrinking of rural population, and stagnating rural households' incomes. On the other hand, as the forth industrial revolution unfolds in earnest, tremendous changes are expected, and those changes won't be confined to certain industries but would shaken the world we know of entirely. Smart farm, which is one example of the fourth industrial revolution, is increasingly being recognized as a new growth engine for the future as smart farm and the science and technology behind it, not the size of arable land, will determine competitiveness of the agricultural industry and drive agricultural productivity and managerial efficiency. In consideration that John W. Kingdon's Multiple Streams Framework has recently been presented as an important theoretical model in the policy field, this study analyzed problem stream, policy stream, and political stream in the process of forming the smart farm policy, and looked into what role the government played as policy entrepreneur in policy window. The smart farm policy was put on policy agenda by the government and was approved when the government announced the Smart Farm Plan together with relevant ministries at the 5th Economy-Related Ministers' Meeting held in April 2018. This suggests that change of the government is the most critical factor in political stream, and explicitly indicates the importance of politics in formation of an agricultural policy. In addition, actual outcome of the policy and how policy alternatives that will enhance people's understanding will support it seem to be the key to success. It also shows that it is important that policy alternatives be determined based on sufficient discussion amongst stakeholders.

As the awareness of food security has increased, the Korean government has established national projects, such as Saemangeum proclaimed land, to secure sources of grain. Saemangeum is a large-scale agricultural area that was constructed to maintain preparedness for unstable food markets. This study aims to develop a $6^{th}$ Industrialization Model (SIM) for Saemangeum Grain Complex by applying feasible strategies to wheat and two-rowed barley which have low self-sufficiency rates. In addition, this study estimates the potential economic value of each development strategy associated with a sixth industrialization model to create higher added values from production, processing and tourism experiences. The strategic plan for primary, secondary, and tertiary industries is to combine cultivating and processing wheat and two-rowed barley for sales and linking them to tourism experience. This study shows value added from the combination of the primary, secondary and tertiary industry of wheat and two-rowed barley are 7.5 and 23.0 times more than those of the primary and tertiary industry combination, respectively. Through branding Saemangeum Grain Complex's products, such as Saemanguem bread and craft beer, would further enhance the economic benefits derived from the complex.

By using the raw data of the 2015 Agriculture, Forestry and Fishery Consensus that surveyed the farmers engaged in agriculture, forestry and fishery in 2015, this study investigated the effects of the characteristics of the farms in Gangwon-do on the utilization of the digital devices, which was classified into computers usage only, smartphones usage only, both computers and smartphones usage, and no digital device usage. This study used the Multinomial Logit Model for the above purpose. Moreover, the IIA(Independence of Irrelevant Alternatives) method of the Multinomial Logit Model was analyzed to be suitable. Upon the result of the analysis, when all the other variables were constant in the average, the probability of choosing both computers and smartphones increased by 0.02% as the family member living together with the farm owner increased by 1 person. In addition, the farms with agricultural machineries have 0.03% increased probability of using smartphones to sell their agricultural products, when compared with the farms without agricultural machinery. Moreover, for the farms with high sales profit of the agricultural products, the probability of using computers and the probability of using smartphones increased by 0.04% and 0.01%, respectively, and the probability of using both computers and smartphones increased by 0.02%. On the other hand, for the farms affiliated with the agricultural organization, the probability of using both computers and smartphones increased by 0.17%, and the probability of using only smartphones and the probability of using only computers increased by 0.16% and 0.15%, respectively. In case of selling to the National Agricultural Cooperative Federation(NACF), the probability of using smartphones increased by 0.11% if all other variables were to be constant in the average. In particular, the farms participating in the agriculture-related industries have 1.09% increased probability of using computers, have 0.92% increased probability of using smartphones, and 0.85% increased probability of using both computers and smartphones. Therefore, the implications suggested based on the results of the analysis are as follows. First, the farms' choices of the digital devices are made independently. Hence, the future agricultural industry business platform establishment should necessarily consider the types of farms' choices of the digital devices in the future. Second, since the usage of digital devices has a generally positive influence on the farm household income, digital education to improve farmers' ability to use the digital devices should be urgently provided in order to improve the farm household income in the farms in Gangwon-do. Third, because the digital devices used to sell agricultural products differ depending on the age of the farm owner, it would be desirable to target the younger generation of the farm owners rather than establishing the agricultural industry business platform for the farms in the aged farm villages. Fourth, it would be advisable for the future agricultural business platform to consider the characteristics of agricultural products sales source.

In the development of policies and projects for regional development, consolidating region's organization and organizational leadership that could establish and operate voluntary developmental plans along with active participations by regional people are important. There have been successful cases of regional agricultural products emphasizing regional characteristics by strengthening functions and autonomy of the local government based on the premise of increasing mealable relationship among local industries and maximizing the characteristics of local resources and local resource utilization. However, effective pursuing is difficult due to lack of organization and leadership. Centering around local units with their importance recognized playing the core role in the development of rural areas, other important issues are activating civic organizations essential for local development based on town units and agricultural amenity resources in rural areas by seeking methods of rearing organizational leadership, improving rural incomes by strengthening local competitiveness through environmentally-friendly agricultural products based on local units, and developing and activating farm experience related with green tour. The types of organization and leaders are analyzed by investigating approved cases of farm experience. According to the results of the analysis, we seek the methods of promoting organizations and leaders for promoting farm experiences in villages and methods of constructing support organizations for promoting farm experience centering around local government units (such as city, Kun, Eup, Myun and village).
