The study intends to seek the creative ideas that can satisfy the needs of individual consumers by rediscovering the modern meaning and the artistic value of geometric ornaments engraved on the backside of Danyugyung, which is a traditional Korean pattern. In terms of the study method, the symbolic meaning and formative characteristics of Danyugyung were determined, and the form of its pattern and the geometric characteristics were analyzed. Based on this, Photoshop and illustrations were used to apply the shapes of Danyugyung and internal patterns to the textile designs, and the results are as follows. Firstly, it was found that Danyugyung was associated with the bronze mirror, which was used from the Bronze Age to the Early Iron Age, and was the product of artistic activities and an object and acted as a shamanistic and authoritative symbol of the ruling parties, which were responsible for the acts related to the spiritual world. Secondly, it was discovered that forms of Danyugyung were classified into Jomungyung and Semungyung in accordance with Forms of Danyugyung (造飾), and the formative features of the geometric ornaments that were engraved in great detail on the backside could be found in the images which change according to the form of the inner patterns. Thirdly, with regard to the development of the textile designs utilizing the shape and inner patterns of Danyugyung based on the formative features, it was could discover that the simple shape of Danyugyung presented a value which can be applied as a unique design factor delivering a visual rhythm by attempting to create various harmonies overlapping lines engraved on the inner patterns and the shapes of Danyugyung. Based on the above-mentioned outcomes, the possibility was confirmed that Danyugyung can be used as a novel motif and as a standard unit of patterns for textile design. With future studies, I would like to utilize the unique and diverse images as pattern motif for textile design.

Cinnamate-4-hydroxylase (C4H) is a key enzyme of phenylpropanoid pathway, which leads a variety of secondary metabolites to participate in differentiation and protection of plant against environmental stresses. In this study, we isolated a full-length cDNA of the C4H gene from a black raspberry (Rubus occidentalis L.), using a reverse transcriptase-PCR and rapid amplification of the cDNA ends (RACE)-PCR. The full-length cDNA of the RocC4H gene contained a 1,515 bp open reading frame (ORF) encoding a 504 amino acid protein with a calculated molecular weight of about 57.9 kDa and an isoelectric point (pI) value of 9.1. The genomic DNA analysis revealed that RocC4H gene had three exons and two introns. By multiple sequence alignment, RocC4H protein was highly homologous with other plant C4Hs, and the cytochrome P450-featured motifs, such as the heme-binding domain, the T-containing binding pocket motif (AAIETT), the ERR triad, and the tetrapeptide (PPGP) hinge motif, were highly conserved. Southern blot analysis revealed that RocC4H is a single copy gene in R. occidentalis.

Modern family culture manifests various different social phenomenon due to shifts caused by increased societal response to industrialization in our country. It is noted that as our lifestyle patterns have shifted from being work-oriented to family-oriented, by focusing on the trend where there is an increase in families enjoying hobby and leisure activities together and where families go shopping together, I attempted to propose various different family-look' designs. In this research study we designed and planned family normal clothes designs that are required and desired for family gatherings and family events, and these designed were produced using 3D virtual clothing design software technology. The research method used the formative features of natural plants and textiles containing a symbolic motif as an element of design, and the creation of family formal clothes were designed and planned based on the method. The development of family formal clothes designs was implemented using CLO 3D virtual clothing design software. Because utilizing 3D virtual clothing design software enables prototyping various types of designs, silhouettes, fabrics and textiles, and color schemes etc. in a short amount of time, it was possible to utilize an advantage from using the software as leveraged to propose designs with a strong symbolic motif and symbolism . Also, by confirming and examining the strengths and weaknesses of the design process when using CLO 3D, It can improve the utilization of IT technologies, and this study aims to provide that efficiency.

The purpose of this study was to categorize the decorative characteristics of the Rococo Age, which displays the most glamorous and elegant decorative beauty, in architecture, interior decorations, paintings, and patterns, and to analyze these characteristics and graft them onto art masks in a modern way. Piece I is a mixed media piece that based its motif on the ceilings and pulpits of the German Vis Pilgrimage Church, which is representative architecture of the Rococo Age. It was glamorously produced using gold and cubic zirconia. Piece II is also a mixed media piece that borrowed its motif from the exterior and gazebo of the Sanssouci Palace in Germany, another representative piece of architecture from the Rococo Age, and it was produced to clearly display the image of the Sanssouci Palace, using emerald and ivory. Piece III applies the furniture trends of the Rococo Age. Curves in S and C shapes, which can often be found in Chinese furniture, along with dark backgrounds, common in portrait paintings, were applied to give a sense of weight and dignity. Piece IV is an application of the fabric patterns of the Rococo Age. Continuous patterns of flowers and greenery stems were drawn on the mask to recreate the fabric patterns of the age. Piece V used the painting 'Swing' of the Rococo Age as its inspiration. Lace and ribbon decorations were used to emphasize feminine beauty and express the loveliness of the woman that appears in the painting. Piece VI borrows from the painting 'Madame de Pompadour' of the Rococo Age and the clothing worn by Pompadour. This piece grafted colors and themes through the painting and expressed a fusion of the dresses of Pompadour and lace that is clearly displayed in the architecture, paintings, clothing, interior decorations, and patterns of the Rococo Age, along with the rocaille (asymmetrically shaped decorations that resemble clams), flowers, leaves, stems, and Chinoiserie styles. These motifs clearly display the decorative characteristics of the age and these were grafted them onto art masks, confirming that it is possible to create new designs.

Background: To date, various genotypes of infectious bronchitis virus (IBV) have co-circulated and in Korea, GI-15 and GI-19 lineages were prevailing. The spike protein, particularly S1 subunit, is responsible for receptor binding, contains hypervariable regions and is also responsible for the emerging of novel variants. Objective: This study aims to investigate the putative major amino acid substitutions for the variants in GI-19. Methods: The S1 sequence data of IBV isolated from 1986 to 2021 in Korea (n = 188) were analyzed. Sequence alignments were carried out using Multiple alignment using Fast Fourier Transform of Geneious prime. The phylogenetic tree was generated using MEGA-11 (ver. 11.0.10) and Bayesian analysis was performed by BEAST v1.10.4. Selective pressure was analyzed via online server Datamonkey. Highlights and visualization of putative critical amino acid were conducted by using PyMol software (version 2.3). Results: Most (93.5%) belonged to the GI-19 lineage in Korea, and the GI-19 lineage was further divided into seven subgroups: KM91-like (Clade A and B), K40/09-like, QX-like (I-IV). Positive selection was identified at nine and six residues in S1 for KM91-like and QX-like IBVs, respectively. In addition, several positive selection sites of S1-NTD were indicated to have mutations at common locations even when new clades were generated. They were all located on the lateral surface of the quaternary structure of the S1 subunits in close proximity to the receptor-binding motif (RBM), putative RBM motif and neutralizing antigenic sites in S1. Conclusions: Our results suggest RBM surrounding sites in the S1 subunit of IBV are highly susceptible to mutation by selective pressure during evolution.

Mono-ADP-ribosylation, catalyzed by ADP-ribosyltransferases, is a post-translational modification of proteins in which the ADP-ribose moiety of NAD is transferred to an acceptor protein. Previously, we have identified and cloned a glycosylphosphatidylinositol-linked ADP-ribosyltransferase (Yac-1) from mouse lymphoma cells. Yac-1 enzyme contains three regions (region I,II,III) similar to those found in several bacterial toxins and vertebrate ADP-ribosyltransferases. Site-directed mutagenesis was performed to verify the role of Glu 233 in region III. Mutants E233Q, E233D and E233A were inactive for ADP-ribosyltransferase activity. Thus Glu 233 in Yac-1 is essential for enzyme activity, suggesting that Glu 233 in Glu-rich motif near the carboxy terminus plays a catalytic role in ADP-ribosyltransferase activity.

The Ribonucleotide reductases (RNR) are essential enzymes that catalyze the conversion of nucleotides to deoxynucleotides in DNA replication and repair in all living organisms. The RNRs operate by a free radical mechanism but differ in the composition of subunit, cofactor required and regulation by allostery. Based on these differences the RNRs are classified into three classesclass I, class II and class III which depend on oxygen, adenosylcobalamin and S-adenosylmethionine with an iron sulfur cluster respectively for radical generation. In this article thirty seven sequences belonging to each of the three classes of RNR were analyzed by using various tools of bioinformatics. Phylogenetic analysis, dot-plot comparisons and motif analysis was done to identify a number of differences in the three classes of RNRs. In this research article, we have attempted to decipher evolutionary relationship between the three classes of RNR by using bioinformatics approach.

A new site-specific recombinase sin, as a component of a putatie transposon has been cloned and its base sequence has been determined. The proposed sin shows a hish degree of homology with pI9789-sin and pSK1-sin. There is a large (16 bp) inverted repeat downstream of proposed sin and the postulate dhelix-turn-helix motif is located at the extreme C-terminus of the poposed Sin. The transposase gene (tnpA) and .betha.-lactamase gene (blaZ) are located upstream of sin and arsenate reductase gene (arsC) and arsenic efflux pump protein gene (ars B) are downstream. This genetic arrangement seems to be a part of a new putative transposon because there is no known transposon with a gene arrangement of tnpA-blaZ-sin-arsC.

This study is the content of the environment-friendly is the tendency of one of postmodernism. Rather than end up post-modernism in the past, such trend has affected many in the design of modern furniture. Appeal to emotion in order to achieve an intimate relationship with the user, especially in the new material, you are the fulfillment of desire more than a simple function. In addition, designers of modern Many or even looking from the re-interpretation of the design past the motif of the design such as the time that post-modernism has arrived. Users who are using the furniture, because there is a tendency to features In addition to the primary that it has, you have to Want the meaning of one another, and to Serve by generating story distance from him this some. In this study, to target households that still is very important in modern design, and a historic of postmodernism the concept with a different meaning functional, the figurative to break free from meaning one-dimensional with the furniture I was analyzed on the basis of the flow.

Protein folding is a fundamental problem in structural bioinformatics and so numerous studies have been devoted to the subject. As the most common regular secondary conformation in proteins, helix has been an important ingredient of the protein folding problem. In particular, alanine based polypeptides are widely studied to identify the helix folding process in that the aianine amino acid is known to have one of the highest helix propensities. In principle, intrinsic helix propensities can be obtained from gas-phase measurements where solvent effect is absent. Hudgins et al. studied alanine-based peptides in vacuo using high-resolution ion mobility measurement technique. It was reported that introduction of a single Iysine at the C terminus resulted in the formation of very stable, monomeric polyalanine helices. We also have investigated helix formation in vacuo with different terminal charge conditions; we have found a new type of helix motif, To the best of our knowledge, this type of helix conformation has not been characterized before and we name it as I-helix.
