Bacillus velezensis strain WRN014 was isolated from banana fields in Hainan, China. Bacillus velezensis is an important member of the plant growth-promoting rhizobacteria (PGPR) which can enhance plant growth and control soil-borne disease. The complete genome of Bacillus velezensis WRN014 was sequenced by combining Illumina Hiseq 2500 system and Pacific Biosciences SMRT high-throughput sequencing technologies. Then, the genome of Bacillus velezensis WRN014, together with 45 other completed genome sequences of the Bacillus velezensis strains, were comparatively studied. The genome of Bacillus velezensis WRN014 was 4,063,541bp in length and contained 4,062 coding sequences, 9 genomic islands and 13 gene clusters. The results of comparative genomic analysis provide evidence that (i) The 46 Bacillus velezensis strains formed 2 obviously closely related clades in phylogenetic trees. (ii) The pangenome in this study is open and is increasing with the addition of new sequenced genomes. (iii) Analysis of single nucleotide polymorphisms (SNPs) revealed local diversification of the 46 Bacillus velezensis genomes. Surprisingly, SNPs were not evenly distributed throughout the whole genome. (iv) Analysis of gene clusters revealed that rich gene clusters spread over Bacillus velezensis strains and some gene clusters are conserved in different strains. This study reveals that the strain WRN014 and other Bacillus velezensis strains have potential to be used as PGPR and biopesticide.

The Ministry of Agriculture and Forestry announced promoting the project, 'Regional Agricultural Clusters,' in Feb. 2004 through 「The Comprehensive Plan for the Agriculture and Agricultural Communities」 and initiated a model project from 2005. The purpose of 'Regional Agricultural Clusters' is to develop regional agriculture by concentrating the resources and capacities of the region and maximizing the effect of integrating related projects. 31 towns in Geonggi and 2 towns (Ganghwa and Ongjin) in Incheon were chosen for the study based on the crop areas of 36 agricultural products from the Agricultural Census in 2000. For those 33 towns, factors such as the top 20 agricultural products, main producing districts and surveys on each towns were considered and we have concluded that these items are good subjects for 'Regional Agricultural Clusters' : We have decided on 18 items for what we call, 'Mini-Clusters,' a cluster in which the item's main producing district is in only one area of the town in question (in 30 projects out of 21 towns). Secondly, we have decided on 11 items for what we call, 'Base-Clusters,' a cluster in which the item's main producing district can be associated by name with the item, the production is sizeable, and can be found in several locations of the town in question (in 13 projects out of 11 towns). Finally, we have decided on 12 items for what we call, 'Broad-Based-Clusters, a cluster which the item's main producing district expands the past the vicinity of the town in question (in 19 projects out of 19 towns).

In Muju County, one of Korea's major apple producers, the regional agricultural cooperatives united together and invested to establish a cooperative joint business corporation in charge of the sales business. The corporation carried out the sales business transferred from the participating regional agricultural cooperatives. While the two participating cooperatives showed a marked difference in the degree of participation at the beginning of the business, the introduction of the agricultural product processing centers (APCs) and the participation of co-selection and shipment organizations and general farms helped settle this gap. In addition, commercialization through the APCs enhanced the market competitiveness of apples, which led to the stable securing of sales outlets. The corporation integrated the sales business in the county and this resulted in increased sales volume and sales revenue. Playing a leading role in introducing and cultivating new crops on a trial basis, the corporation demonstrated its potential as the main body of the joint sales business.

The purpose of the present study is to construct a rural development strategy from the nexus between spatial changes in specialized crops and suitable cultivation area of the crops. This paper pays particular attention to identify product life cycle of specialized crops in rural areas and estimate the impact of climate change on alterations in spatial distribution of the crops. In order to do so, first of all, this study applies multi-level model (Random coefficient model) to estimate the regional coefficient of five orchard crops. It utilizes the data 1995 to 2010 Korea Agricultural Census. Futhermore, it also adopts overlay analysis by ArcGIS to identify the development path of the crops and the relationship with climate change. Based on the results, it suggests a mechanism activating regional agriculture. The findings propose re-searching and relocating specialized regions of the crops. Especially, it proves each rural area can drive the new agricultural strategy to strengthen regional agriculture by estimating the relationship between development of specialized crops and suitable cultivation areas. For instance, shifting specialized crops in particular regions and enriching genetic or species varieties can be primary measures and it will contribute to improve the reliable base for income sources in the rural communities. This paper also offers specific policy implications regarding rural development plans in response to crops' life cycle and climate changes.

This study aims to analyze the regional variations in which appear during the formation process of educational community in rural villages from the perspective of regional innovation theory. The study results revealed that the activities to form an educational community of the Songak village significantly influenced the variations across the social, economic and environmental aspects beyond an innovation of public education within the region based on interrelation between schools and villages. In other words, the activities including interactions and group learnings have been actively promoted among the various relevant stakeholders, thereby resulting in a variety of positive variations such as expanded regional welfare base, activated voluntary residents community gatherings based on the unity and cooperation, broadened socioeconomic opportunities, satisfaction on educational and cultural desires, and construction of healthy ecological environment in the region. Therefore, it is thought that regional development policy suitable for each region needs to be established by embracing the fact that activities to form a village educational community entail significant implication and value as the comprehensive regional innovation activities across the entire domains in each region.

The purpose of this study is to explore the key elements of the regional innovative milieu by analyzing the role of regional innovative elements and case organizations that promoted the emergence of 'Songakdongnesaramdeul (the people of the Songak town),' and to present pertinent policy implications. For the purpose, this study set the "Songakdongnesaramdeul," a residential community organization founded for regional innovation to revitalize the village community, as a case organization from the perspective of regional innovation system theory. The result of the study showed that creating an innovative milieu through the creation of various innovation elements to revitalize the village community is crucial. Especially, this study confirmed that the existence of regional development organizations is the key element of the innovative milieu. such as case organization that contributes to regional development while promoting interaction between actors, common learning and systemization, and new value creation activities. The implications derived through the study can be summarized in four points. First, a variety of means to promote the formation of subjects in response to the public debate of the village agenda is needed. Second, it is highly important to create innovative elements, for example, organizations and programs, resources, and spaces that promote regional innovation. Third, forming a close network between various innovative resources existing in the region and establishing regional capabilities that allow to mobilize and utilize such innovative resources are important. Fourth, the establishment of a promotion mechanism such as a case organization is suggested as a major task, to revitalize the village community. Specifically, forming and revitalizing numerous private-based community organizations with regional developmental capabilities to establish local governance also has significant importance. In this vein, based on the point of view of the regional innovation system theory, the establishment of regional policies to construct a regional innovation milieu, such as creating innovative elements that can actively promote the regeneration of the village community and establishing a promotion system, can be presented as major tasks.
