Diffusion of non-professional flower growing in Korea still lags behind. The objectives of the study are to establish a theoretical modes to explain the diffusion of social floriculture, to identify some characteristics and problems of growing flower crops to cultivate amenities and emotions, and to suggest remedial measures for fostering it. Theoretical model adopted in this study consists of such variables as education, social movement, policies, diffusion of social flower growing, amenities, and emotional cultivation. For identifying the diffusion characteristics of flower growing, projects implemented by a non-governmental organization, schools, local and central government organizations were analyzed. In order to stimulate the diffusion of social flower growing and to increase its effects, there needs to strengthen education of stakeholders, establishment of partnership among schools, non-governmental and governmental organizations, and institutional supports including manpower and finances. Linking flower growing projects to community festival and tourism development programs can foster institutionalization of community flower growing. Furthermore, the introduction of wild, symbolic and traditional flowers and trees will help to specialize and improve community landscapes.

Because of the international marriage of bachelors in the rural areas, there have been grown many foreign residents, the Multi-cultural families. For the improvement of multi-cultural families, the first important thing is their early settlement in Korea. For those foreigners' settlement, systematic approach to Korean education program is necessary. Second, multi-cultural families need support to maintain their basic lives safely. Agricultural education for the next generation is, moreover, also important for them. Third, healthy growth and training for the formation of the Self-Identity of their children are needed for those multi-cultural families too. Education for bring up their children as the global talents, the cost of private education and the one of bringing up children also have to be supported. Fourth, the improvement of understanding multicultural families is significant. Development and education of various programs to participate multi-cultural families are also required.

This study aims to examine the needs analysis for agricultural management capabilities and farming practices that were emphasized by focusing to the inflow of farmers and the importance of the smooth succession. Data were collected from 134 farm successors. The Borich demand and the Locus for Focus model were hired for the study. Result were as follows. The competency group that the farm successors showed a high educational needs for was financial management. As for the detailed competencies that farm successors showed high educational needs for, based on Borich demand and the Locus for Focus model, the six detailed competencies of financial measures, financial analysis, financial management, sales planning, machine operation, and pest management were common and were derived as priorities. As for the direction of farming practice education for farm successors, based on these analysis results, education on machinery operation in the production sector should be expanded, and the management sector, more systematic and diverse education should be prepared to strengthen financial management capabilities.

While the main purpose of irrigation reservoirs is to supply agricultural water, the needs of environmental flow and flood control has been expanded. The agricultural reservoirs have been operated in the form of carry-over system until now. Therefore, the supply of agricultural water is difficult when the storage rate is not sufficiently secured after large volume of irrigation. In addition, there are regulation of the upper storage rate for some large reservoirs during the flood season, but lower storage rate is not regulated. Accordingly, this study aims to evaluate the capacity of agricultural water and environmental flow supply by setting the management lower storage rate of reservoir. The changes in the supply of agricultural and environmental flow was simulated according to the three different regulating lower storage rate scenarios. As a result, it was judged effective in terms of water supply managing the lower storage rate up to 30% when the initial storage rate of farming period is above annual average for the Naju reservoir considering existing water management practice. If the lower storage rate would have been controlled above 30%, the supply of agricultural water might be increased and non-effective discharge amount would be decreased compared to other scenarios during dry period of 2016-2018.

Background: Antimicrobial peptides (AMPs) have been identified as promising compounds for consideration as novel antimicrobial agents. Objectives: This study analyzed the efficacy of cecropin B against Haemophilus parasuis isolates through scanning electron microscopy (SEM) and atomic force microscopy (AFM) experiments. Results: Cecropin B exhibited broad inhibition activity against 15 standard Haemophilus parasuis (HPS) strains and 5 of the clinical isolates had minimum inhibition concentrations (MICs) ranging from 2 to 16 ㎍/mL. Microelectrophoresis and hexadecane adsorption assays indicated that the more hydrophobic and the higher the isoelectric point (IEP) of the strain, the more sensitive it was to cecropin B. Through SEM, multiple blisters of various shapes and dents on the cell surface were observed. Protrusions and leakage were detected by AFM. Conclusions: Based on the results, cecropin B could inhibit HPS via a pore-forming mechanism by interacting with the cytoplasmic membrane of bacteria. Moreover, as cecropin B concentration increased, the bacteria membrane was more seriously damaged. Thus, cecropin B could be developed as an effective anti-HPS agent for use in clinical applications.

The full-length cDNA of the porcine peroxisomal ${\Delta}^3$,${\Delta}^2$-enoyl-CoA isomerase (PECI) gene encodes a monofunctional peroxisomal ${\Delta}^3$,${\Delta}^2$-enoyl-CoA isomerase. Cloning and sequencing of the porcine PECI cDNA revealed the presence of an 1185-base pair open reading frame predicted to encode a 394-amino acid protein by the 5'rapid amplification of cDNA ends (5'RACE) and EST sequences. The porcine PECI gene was expressed in seven tissues (heart, liver, spleen, lung, kidney, skeletal muscle, fat) which was revealed by reverse transcriptase-polymerase chain reaction (RT-PCR). The porcine PECI was mapped to SSC71/2 p11-13 using the somatic cell hybrid panel (SCHP) and the radiation hybrid panel (RH) (LOD score 12.84). The data showed that PECI was closely linked to marker S0383. A C/T single nucleotide polymorphism in PECI exon 10 (3'UTR) was detected as a PvuII PCR-RFLP. Association analysis in our experimental pig population showed that different genotypes of PECI gene were significantly associated with the Average Backfat thickness (ABF) (p<0.05) and Buttock backfat thickness (p<0.01).

Four-and-a-half LIM-only protein 3 (FHL3) is a member of the LIM protein superfamily and can participate in mediating protein-protein interaction by binding one another through their LIM domains. In this study, the 5'- and 3'- cDNA ends were characterized by RACE (Rapid Amplification of the cDNA Ends) methodology in combination with in silico cloning based on the partial cDNA sequence obtained. Bioinformatics analysis showed FHL3 protein contained four LIM domains and four LIM zinc-binding domains. In silico mapping assigned this gene to the gene cluster MTF1-INPP5B-SF3A3-FHL3-CGI-94 on pig chromosome 6 where several QTL affecting intramuscular fat and eye muscle area had previously been identified. Transcription of the FHL3 gene was detected in spleen, liver, kidney, small intestine, skeletal muscle, fat and stomach, with the greatest expression in skeletal muscle. The A/G polymorphism in exon II was significantly associated with birth weight, average daily gain before weaning, drip loss rate, water holding capacity and intramuscular fat in a Landrace-derived pig population. Together, the present study provided the useful information for further studies to determine the roles of FHL3 gene in the regulation of skeletal muscle cell growth and differentiation in pigs.

Securing food safety, natural and social environmental protection, and activation of rural communities are some of challenging tasks for the 21st century. National consensus on agriculture as a basic and public industry would be needed to solve these challenging tasks. Agricultural policy and extension education should be focused on encouraging farmers to achieve better production and management by developing their motivation and ability. Systematic and organizational efforts to make a better environment for farming and farm management should be the major target of agricultural policy and extension services in the future. To meet changing needs of farmer, agricultural extension services should change programs, functions, information sources, and methods of delivery to adopt experiential learning for farmers. Functions for consultation, suggestion and organization should be extended and advisory services for farmers should be emphasized by providing extension education.
