Most traditional genome sequencing projects involving infectious viruses include culturing and purification of the virus. This can present difficulties as an analysis of multiple populations from multiple locations may be required to acquire sufficient amount of high-quality DNA for sequence analysis. The electrophoretic method provides a strategy whereby the genomic DNA sequences of the Korean isolate of Pieris rapae granulovirus (PiraGV-K) were analyzed by purifying it from host DNA by pulsed-field gel electrophoresis, thus simplifying sampling and labor time. The genomic DNA of infected P. rapae was embedded in agarose plugs, digested with a restriction nuclease and methylase, and pulsed-field gel electrophoresis (PFGE) was used to separate PiraGV-K DNA from the DNA of P. rapae, followed by mapping of fosmid clones of the separated viral DNA. The double-stranded circular genome of PiraGV-K encodes 120 open reading frames (ORFs), covering 92% of the sequenced genome. BLAST and ORF arrangement showed the presence of 78 homologs to other genes in the database. The mean overall amino acid identity of PiraGV-K ORFs was highest with the Chinese isolate of PiraGV (~99%), followed up with Choristoneura occidentalis ORFs at 58%. PiraGV-K ORFs were grouped, according to function, into 10 genes involved in transcription, 11 involved in replication, 25 structural protein genes, and 15 auxiliary genes. Genes for Chitinase (ORF 10) and cathepsin (ORF11), involved in the liquefaction of the host, were found in the genome. The recovery of PiraGV-K DNA genome by pulse-field electrophoretic separation from host genomic DNA had several advantages, compared with its isolation from particles harvested as virions or inclusions from the P. rapae host. We have sequenced and analyzed the 108,658 bp PiraGV-K genome purified by the pulsed field electrophoretic method. The method appears to be applicable to the analysis of genomes of large viruses. The chitinase, identified by PiraGV-K genome sequence, was functionally characterized by quantitative PCR, Western blot analysis, immunohistochemistry and transmission electron microscopy.

Engl ish as a Foreign Language (EFL) students in traditional second language (L2) writing classrooms are not provided sufficient opportunities for giving and receiving peer feedback. To compensate for this limitation, blended learning has been suggested in the L2 writing classroom. However, there has been little research on peer feedback in blended learning in L2 writing. Therefore, this study aims to investigate the patterns of peer feedback and the impact of peer feedback on revisions in blended leaming in L2 writing. The subjects for the qualitative study consisted of three university students, representing low- intermediate, intermediate, and advanced levels of English writing proficiency. Data sources included student-produced feedback in online and offline sessions, 18 drafts in process-oriented writing, classroom observations, and the interview. The major fi ndings of the study are as fo llows. First, the students produced more onl ine peer feedback than offline peer feedback. Second, they provided more fonn-focused feedback in online sessions, but more meaning-focused feedback in offline sessions. Third, they incorporated online peer feedback in their second drafts more than offline peer feedback in the final drafts. Based on the findings, implications are considered and suggestions are made for the effective use of peer feedback in blended learning in L2 writing .

Insects or insect remains found in beer are one of major issues in consumer claim. Accurate estimation of inflow time isa critical factor for the settlement of such claims related with beer-contaminating insects but no reliable methods have been developed. In an attempt to establish a molecular marker-based diagnostic method, the degradation rates of 18S rRNA genes in the insectssoaked in 500 ml beer were investigated by quantitative real-time PCR (qPCR) over one month period at room temperature. Among the six insect species tested, the house fly (Musca domestica) and honey bee (Apis mellifera) revealed high correlations (r2=0.974-0.990) between the degradation of 18S rRNA gene and inflow time. In these insects, statistically significant distinction was possible between the samples stored in beer less than 14 days and more than 14 days. Other insects, including the fruit fly, common house mosquito, German cockroach and Indian meal moth, displayed poor correlations, which appeared attributed to the inefficient genomic DNA extraction likely due to small sample size or disintegration of body parts during storage in beer. With proper improvement in DNA extraction, this 18S rRNA-based diagnostic method would be applicable for estimating the inflow time of beer-contaminating insects.

The Mental Image is designed and proposed for making a comfort and amenity in built environments using digital color analysis in the regional urban artificial environment. For a long time, it is crucial to relate visual environment with thermal environments. Especially, color makes an important role to making thermal comfort. In order to making this information, this paper describes how we can analyze the color information of the regional urban artificial environment using the color syntax program and transfer the data to form maker and create the mental image. Because of the rapid urbanization and the acceptance of mixed function, modern urban landscape is disordered and is not controlled. The Mental Image prepares our environmental color system corresponding to our mental image with perceiving regional urban environment color. This research aims to systematize the process making the Mental Image in the regional urban landscape’s color and suggest a theoretical basis to extract, embody and use the information of the regional main color from urban landscape color. Through these concepts, this research will suggest how to systematize, develop the Mental Image with emotional environmental color system. Finally, it is expected to offer a theoretical basis to embody the Mental Image and build up the emotional environments.

In this study, we determined the complete mitochondrial genome of the jewel beetle, Chrysochroa fulgidissima (Coleoptera: Buprestidae), from four overlapping fragments. The 15,592-bp long C. fulgidissima mitogenome exhibits a gene arrangement and content identical to the most common type in insects. The start codon of the C. fulgidissima COI gene is unusual, in that no typical ATN codon is available. The 875-bp A+T-rich region is the shortest among the coleopteran mitogenomes that have thus far been sequenced in their entirety. The most unusual feature of the genome is the presence of three tRNA-like sequences within the A+T-rich region: two tRNALeu(UUR)-like sequences and one tRNAAsnlike sequence. These sequence stretches evidence the proper anticodon sequence and the potential to form secondary structures, but also harbor many mismatches in the stems. Phylogenetic analysis using a concatenation of 13 amino acid sequences of protein-coding genes among the available sequenced species of coleopteran superfamilies (Buprestoidea and Elateroidea belonging to the infraorder Elateriformnia, and Chrysomeloidea and Tenebrioroidea belonging to the infraorder Cucujoiformia) by Bayesian inference, maximum-parsimony analyses, and maximum-likelihood analysis unexpectedly revealed a lack of support for monophyletic Elateriformia.

We present BV CCD photometry for the open clusters Czernik 24 and Czernik 27. These clusters have never been studied before, and we provide, for the first time, the cluster parameters; reddening, distance, metallicity and age. Czernik 24 is an old open cluster with age 1.8 ± 0.2 Gyr, metallicity [Fe/H]=-0.41 ± 0.15 dex, distance modulus (m-M)0=13.1 ± 0.3 mag (d=4.1 ± 0.5 kpc), and reddening E(B-V)=0.54 ± 0.12 mag. The parameters for Czernik 27 are estimated to be age=0.63 ± 0.07 Gyr, [Fe/H]=-0.02 ± 0.10 dex, (m-M)0=13.8 ± 0.2 mag (d=5.8 ± 0.5 kpc), and E(B-V)=0.15 ± 0.05 mag. The metallicity and distance values for Czernik 24 are consistent with the relation between the metallicity and the Galactocentric distance of other old open clusters. We find the metallicity gradient of 51 old open clusters including Czernik 24 to be Δ[Fe/H]/ΔRgc = -0.064±0.009 dex kpc-1.

The well observed 8 open clusters, NGC 6530, 2264, 654, 129, 2168, Pleiades, Praesepe and Hyades were selected on the basis of photometric observation and proper motion study. The luminosity functions (LF) and mass functions (MF) of these clusters are different with cluster age and they could be divided into three age groups (t< 10 7 yrs, 10 7 10 8 yrs, 10 8 10 9 yrs). From these LF's and MF's, the mean LF and MF of the open clusters are derived and these functions suggest the time-dependent initial mass function (IMF) and the variation of observed MF with cluster age.

The isolated single coronary artery is a rare congenital anomaly, in which both coronary arteries arise from a solitary ostium. Diagnosis of coronary anomalies and identification of the exact anatomy of coronary arteries has significant clinical importance, hence, myocardial ischemia or sudden cardiac death is usually related to its course of anomalous coronary artery. Most patients with a single coronary artery are asymptomatic and have normal electrocardiogram and negative stress tests. However, if the patient has other structural abnormalities, for example, ventricular hypertrophy, the exam is determined. This report describes a case of single coronary artery, where the right coronary artery originated from the distal left circumflex artery in a patient with hypertrophic ardiomyopathy.

Mungbean (Vigna radiata) is a fast-growing, warm-season legume crop that is primarily cultivated in developing countries of Asia. We constructed a draft genome sequence of mungbean to facilitate genome research into the subgenus Ceratotropis and to enable a better understanding of the evolution of leguminous species. The draft genome sequence covers 80% of the estimated genome, of which 50.1% consists of repetitive sequences. In total, 22,427 high confidence protein-coding genes were predicted. Based on the de novo assembly of additional wild mungbean species, the divergence of what was eventually domesticated and the sampled wild mungbean species appears to have predated domestication. Moreover, the de novo assembly of a tetraploid Vigna species (Vigna reflexo-pilosa var. glabra) provided genomic evidence of a recent allopolyploid event. To further study speciation, we compared de novo RNA-seq assemblies of 22 accessions of 18 Vigna species and protein sets of Glycine max and Cajanus cajan. The species tree was constructed by a Bayesian Markov chain Monte Carlo method using highly confident orthologs shared by all 24 accessions. The present assembly of V. radiata var. radiata will facilitate genome research and accelerate molecular breeding of the subgenus Ceratotropis.

Arabidopsis atDjC53 and atDjC32 gene DnaJ-like protein homologous to DnaJ-like protein was characterized for the functional analysis of DnaJ-like protein. It was shown that atDjC53 and atDjC32 RNA expression is induced by heat shock stress and atDjC53- and atDjC32-GFP was targeted to the nucleus of protoplasts. The atDjC53 and atDjC32 promoter (1 kb) was isolated and fused to the GUS reporter gene to investigate gene regulation of atDjC53 and atDjC32 specific to heat shock stress or to developmental organ in the transgenic lines. RNAi and overexpression construct was employed to generate atDjC53 and atDjC32 knock-out plants for the study of their function. Molecular function of atDjC53 and atDjC32 is discussed in relation to heat shock and also developmental stages in Arabidopsis.

Heat shock transcription factors (HSFs) are the major heat shock factors regulating the heat stress response. They participate in regulating the expression of heat shock proteins (HSPs), which are critical in the protection against stress damage and many other important biological processes. In this study, a genome-wide analysis was carried out to identify all HSFs soybean genes. Twenty six nonredundant HSF genes (GmHsf) were identified in the latest soybean genome sequence. Chromosomal location, protein domain and motif organization of GmHsfs were analyzed in soybean genome. The phylogenetic relationships, gene duplications and expression profiles of GmHsf genes were also presented in this study. According to their structural features, the predicted members were divided into the previously defined classes A–C, as described in Arabidopsis. Using RT-PCR, the expression patterns of 26 GmHsf genes were investigated under heat stress. The data revealed that these genes presented different expression levels in response to heat stress conditions. Real-time (q)RT-PCR was performed to investigate transcript levels of five GmHsfs in response to multiple abiotic stresses. Differential expression of five GmHsfs implies their role during abiotic stresses. Subcellular localization using GFP-fusion protein demonstrated that GmHsf12 and GmHsf34 were restricted to the nucleus and GmHsf28 was localized in the nucleus and cytoplasm in plant. The results provide a fundamental clue for understanding of the complexity of the soybean HSF gene family and cloning specific function genes in further studies and applications.
