This study was aimed to investigate the nutritional components such as proximate content, minerals, vitamins, and dietary fiber of Euonymus sieboldiana leaves. The leaf sample used was fresh material produced in April in the Republic of Korea. As a result, the fresh leaf sample contained 10.30% crude carbohydrates, 7.42% crude proteins, 0.69% crude fat, and 1.46% crude ash, including a high amount of potassium (0.73%). The total dietary fiber, insoluble dietary fiber, and soluble dietary fiber content was 8.77%, 7.60%, and 1.17%, respectively. Vitamin C was found to be 44.53 mg% using colorimetric analysis. We regarded E. sieboldiana as a potential health food material because of its abundant nutritional components like potassium, dietary fiber, and vitamin C.

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.

This study aimed to draw the plan elements and characteristics that should be considered in case when developing guidelines to build up roads in rural villages. Drawing the construction elements necessary for building up roads through the advanced researches, the survey was conducted for relevant experts in order to evaluate the importance of each plan element of route plan, design & construction and operation & management. The result determined total 105 contents that should be considered in case when building up roads in rural villages. The study on building up roads in rural villages as a strategy to vitalize rural areas means universal roads that connect each village with rural amenities in various values like walking tour road, visit roads and observation roads. It is considered that the development of guidelines for building up roads in rural villages could be used as a basic data to build up roads where nature, culture and history of rural areas can be effectively experienced and enjoyed.

The purpose of this study is to develop a culture and leisure resources scale and examine the validity of the scale. The culture and Leisure resources scale was developed and identified its validity by exploratory factor analysis, confirmatory factor analysis, and correlation analysis. The culture and leisure resources scale consisted of four factors, which were 'personal resources', 'support staff resources', 'facility resources', and 'program resources'. Those four factors indicated the reasonable fit indices from confirmatory factor analysis. In addition, this scale showed convergent validity with the satisfaction of cultural and leisure environment and the satisfaction of one's cultural and leisure life. The result of scale score comparison between rural and urban areas showed that culture and leisure resources in rural areas were less abundant than those in urban areas. Furthermore, while the variables which affected the satisfaction of urban residents' were mainly 'personal resources', the variables in case of rural residents' were mainly 'program resources' and 'facility Resources'. The culture and leisure resources scale can be used for policymakers practicably to evaluate regional level of culture and leisure resources, to compare between regions and to find policy priorities for improving the quality of leisure, especially for disadvantaged areas with less resources.

Composting is widely used to transform waste into valuable agricultural organic fertilizer. Anaerobic ammonium-oxidizing (anammox) bacteria play an important role in the global nitrogen cycle, but their role in composting remains poorly understood. In the present study, the community structure, diversity, and abundance of anammox bacteria were analyzed using cloning and sequencing methods by targeting the 16S rRNA gene and the hydrazine oxidase gene (hzo) in samples isolated from compost produced from cow manure and rice straw. A total of 25 operational taxonomic units were classified based on 16S rRNA gene clone libraries, and 14 operational taxonomic units were classified based on hzo gene clone libraries. The phylogenetic tree analysis of the 16S rRNA gene and deduced HZO protein sequences from the corresponding encoding genes indicated that the majority of the obtained clones were related to the known anammox bacteria Candidatus "Brocadia," Candidatus "Kuenenia," and Candidatus "Scalindua." The abundances of anammox bacteria were determined by quantitative PCR, and between $2.13{\times}10^5$ and $1.15{\times}10^6$ 16S rRNA gene copies per gram of compost were found. This study provides the first demonstration of the existence of anammox bacteria with limited diversity in cow manure composting.
