        The purpose of this study was to develop a lifestyle scale for one-person hair salon users and to identify differences in store choice factors and hairstyle pursuit behaviors according to lifestyle types. Data was collected by survey, with 225 responses being included in the analysis. Data analysis was performed using cross-analysis, factor analysis, Cronbach’s α, cluster analysis, ANOVA and the Duncan-test using SPSS 23.0 analysis software. The results of the study were as follows. First, one-person hair salon users were classified according to the following lifestyle groups: The rational appearance management group, the passive appearance management group, and the discriminative appearance management group. Second, store choice factors according to lifestyle group showed significant group-specific differences in relation to store atmosphere, accessibility, and promotion. Conversely, comfort of space in store and word-of-mouth recommendation message were high for all three groups, indicating that these are important factors in relation to store selection. Third, with regard to hairstyle pursuit behaviors according to lifestyle, the discriminative appearance management group showed the same characteristics as high involvement groups that regard all dimensions of hairstyle pursuit behavior as important. The results of this study can be used to suggest efficient operations for one-person hair salons and to suggest differentiated marketing strategies to increase the demand of one-person hair salon users.

        In this study, activated carbon with well-developed mesopores was fabricated using kenaf short fibers as a representative biomass. Concentrated phosphoric acid was selected as an activation agent to create highly developed porous structures, and pore development was observed to occur in relation to the weight ratio of phosphoric acid and kenaf. The pore characteristics of the kenaf-based activated carbon were determined using the N2/ 77K adsorption isotherm, and its microcrystalline structure was analyzed using X-ray diffraction. The highest specific surface area (1570 m2/g) was observed when the weight ratio of phosphoric acid to kenaf was 3:1, and the highest mesopore fraction (74%) was observed at 4:1. The carbonization yield was 45–35%, which is higher than that of commercial activated carbon. The production of porous carbon material by this method offers high potential for application because it can be controlled over a wide range of average pore diameter from 2.48 to 5.44 nm.

        Meedon rice varieties are important for local adaptability, grain quality and market availability, and have been grown in Myanmar for centuries. Because of temporal variability and spatial heterogeneity, Meedon rice varieties in rainfed lowland areas may be diverse. However, information on diversity of Meedon rice germplasm is limited. This study was carried out to assess genetic diversity and to analyze population structure of Meedon rice germplasm conserved in Myanmar Seed Bank using SSR markers. For assessing genetic diversity, 154 accessions of Meedon rice germplasm were analyzed with nine SSR markers. A total of 86 alleles were detected with an average of 9.6 alleles per locus. All the loci were found to be polymorphic, and there were considerable genetic variation among accessions with mean values of expected heterozygosity (HE) = 0.5774 and polymorphic information content (PIC) = 0.5496. High frequency of rare alleles was identified, among which 35 unique (accession-specific) alleles were observed. Based on cluster analysis, rice accessions were mainly clustered into two groups, and as a result of model-based analysis, two distinct genetic populations and an admixture were classified. This result indicated that SSR markers have proved to be useful markers for detecting genetic diversity in Meedon rice, and the occurrence of a considerably high number of rare and unique alleles in the germplasm indicates their potentiality as a reservoir of rare genotypes for use. Unique alleles are also important because they may be diagnostic of a particular type of genotype for identification.

        Doenjang is one of the most favorite traditional food which was produced by the fermentation process of soybean with various microbes such as Aspergillus oryzae, Bacillus subtilis and so on. The aim of this research is to analyse the antioxidant and anti-α-glucosidase inhibitory activities of doenjang made by 9 different cultivar (Daewonkong, Taekwangkong, Daepungkong, Hwangkeumkong, Saedanbaek, Hanolkong, Pungsannamulkong, Cheongja-3 and Cheongdu-1). Doenjang samples were made by traditional manner using rice straw. Each samples were extracted with 40% methanol and extract were used Among them, cheongja-3‘s doenjang showed a significant highest antioxidant and anti-α-glucosidase inhibitory activities because of its anthocyanin. Except for cheongja-3's Doenjang, antioxidant activity had positive correlation with isoflavone content. But no relationship observed between isoflavone content and anti-α-glucosidase activity. The highest anti-α-glucosidase activity was observed in Saedanbaek's Doenjang with highest protein content.

        UNUSUAL FLORAL ORGAN (UFO), a novel gene, is involved in controlling flowering initiation and development. In Arabidopsis, UFO is required for floral organ identity in the second and third whorls. However, the mode of expression and function of TaUFO have not been studied yet. The cDNA sequence of TaUFO is comprised of 1344 bp open reading frame which encodes 50.82 KDa polypeptide consisting amino acid residues. F-box protein, the components of TaUFO, plays an important regulatory role in a wide diversity of developmental and physiological responses. In almost all F box proteins, the N terminus of the protein contains the F-box motif, and the rest of the protein contains the protein-protein interaction domains required for target protein binding. In order to elucidate the function of the TaUFO, various phytohormones and abiotic stresses were applied on young seedlings (14 day after germination) and its transcripts were evaluated. TaUFO:GFP fusion construct was transformed into onion epidermal cells by particle bombardment to elucidate the subcellular localization of the TaUFO protein. The function of the F-box protein is to interact with target proteins. With the use of a yeast two-hybrid screen to isolate proteins interacting with the TaUFO (F box protein), we identified potential TaUFO interactive protein in wheat spikelet library.

        It was previously pointed out that mutation is the ultimate source of variation. Adequate variation is needed for plant breeding if there is a limitation in natural genetic resources. When the ionizing radiation has been known to cause chromosomal and genomic alternations, it is widely used for inducing mutagenesis. The electron beam as an ionizing radiation is the principal physical mutagens that induces mutation and effectively used in plant breeding. Since dose-response relationships of electron beam in plant species are rarely known, we investigated the seed germination rate and early seedling growth of irradiated seeds of creeping bentgrass (Agrostis palustris Huds., cv Penn-A1) with various electron beam irradiating conditions (1, 1.3, 2 MeV at both 0.03 mA and 0.06 mA with dose of 100 Gy (Gray) and 0.03, 1, 1.3, 2 MeV at 0.03 mA with dose of 200 Gy, respectively) using electron accelerator at Korea Atomic Energy Research Institute. The growth parameters in terms of shoot length, primary root length, and secondary root length showed similar response between 0.06 / 1 (mA / MeV) at 100 Gy and 0.03 / 0.3 (mA / MeV) at 200 Gy. Bentgrass seed germination was mainly affected by the intensity of irradiated dose (Gray). Germination rate was lowered as the irradiated dose increased. On the other hand, early seedling growth was mainly governed not by the dose of radiation but by voltage.
