In human and robot interaction, the role of emotion becomes more important Therefore, robots need the emotion expression mechanism similar to human. In this paper, we suggest a new emotion expression system based on the psychological studies and it consists of five affective elements, i.e., the emotion, the mood, the personality, the tendency, and the machine rhythm. Each element has somewhat peculiar influence on the emotion expression pattern change according to their characteristics. As a result, although robots were exposed to the same external stimuli, each robot can show a different emotion expression pattern. The proposed system may contribute to make a rather natural and human-friendly human-robot interaction and to promote more intimate relationships between people and robots.

The human homolog of position specific element of mouse Hoxa-7 was studied using transgene. It contains a 1.1 kb human DNA (HCR)- a homolog to the intergenic region between Hoxa-7 and -9, which directs the position specific expression of Hoxa-7-, tk promoter, LacZ (${\beta}$-galactosidase) gene as a reporter, and polyadenylation signal of SV40 large T antigen. It was injected into the mice embryos, and the resulting transgenic embryos were analysed through PCR as well as genomic Southern blotting with placenta DNA. Out of 20 embryos analysed, two were transgenic. Among them, one transgenic embryo expressed transgene when stained with X-gal. The expression pattern was in analogy to that of the mouse Hoxa-7, showing spatially restricted expression pattern, Since the expression of ${\beta}$-galactosidase is regulated by the upstream human HCR sequence, it implies that the HCR is the plausible position specific regulatory element of human.

This study was conducted in order to analyze draping and flat pattern according to jacket design, and provide basic materials for developing a jacket pattern that can enhance fitness, functionality, and aesthetic expression of clothes by reflecting esthetic expression of draping and efficiency of flat pattern at the same time. For the experimental jacket designs of a one-piece sleeve jacket and a two-piece sleeve jacket were selected among the entries of the designer Rubina for 2014 F/W Seoul Fashion Week. Designer brand Rubina usually produced clothes using draping and the designer brand company provided the experimental patterns for the study. We also had flat patterns of the same design and size specifications designed by a flat patternmaker who has 30 year-experience in flat pattern like Rubina. The test apparel jacket was made of 20's cotton yarns. Three models wore the jackets and evaluation on appearance fitness was conducted by 7 members in an expert panel group from August 10, 2015 to September 10, 2015. As a result of appearance fitness analysis on one-piece sleeve jacket, there were significant difference in 4 items among 17 items in terms of overall appearance. The appearance of jackets by draping had higher score than those using flat pattern. As for two-piece sleeve jacket, there were significant differences in 7 items among 17 items related to overall appearance. As for the items related to sleeve, 5 items out of 13 showed significant differences. Except for one item, appearance of jackets using draping had higher score than flat pattern. As for motion fitness, draping was evaluated to be more comfortable. Applying the items with high scores in appearance and motion fitness in draping to flat pattern, The study suggests a new jacket pattern development that would increase the satisfaction of consumers for future research.

Groups of genes control the functioning of a cell by complex interactions. Such interactions of gene groups are tailed Gene Regulatory Networks(GRNs). Two previous data mining approaches, clustering and classification, have been used to analyze gene expression data. Though these mining tools are useful for determining membership of genes by homology, they don't identify the regulatory relationships among genes found in the same class of molecular actions. Furthermore, we need to understand the mechanism of how genes relate and how they regulate one another. In order to detect regulatory relationships among genes from time-series Microarray data, we propose a novel approach using frequent pattern mining and chain rules. In this approach, we propose a method for transforming gene expression data to make suitable for frequent pattern mining, and gene expression patterns we detected by applying the FP-growth algorithm. Next, we construct a gene regulatory network from frequent gene patterns using chain rules. Finally, we validate our proposed method through our experimental results, which are consistent with published results.

Recently, the RNA/DNA-binding protein FUS, Fused in sarcoma, was shown to play a role in growth, differentiation, and morphogenesis in vertebrates. Because little is known about Fus, we investigated its expression pattern in murine tooth development. In situ hybridization of mouse mandibles at specific developmental stages was performed with a DIG-labeled RNA probe. During early tooth development, Fus was detected in the dental epithelium and dental mesenchyme at 11 days postcoitum (dpc) and 12 dpc. From 14 dpc, Fus was strongly expressed in the dental papilla and the cervical loop of the dental epithelium. At postnatal day 4 (PN4), Fus expression was observed in the odontoblasts, ameloblasts, the proliferation zone of the pulp, and the cervical loop. At PN14, the expression pattern of Fus was found to be maintained in the odontoblasts and the proliferation zone of the pulp. Furthermore, Fus expression was especially strong in the Hertwig's epithelial root sheath (HERS). Therefore, this study suggests that Fus may play a role in the HERS during root development.

Ionizing radiation is a well- known therapy factor for human carcinoma cells. Genotoxic stress mediates cell cycle control, transcription and cellular signaling. In this work, we have used a microarray hybridization approach to characterize the cell type-specific transcriptional response of human carcinoma MCF-7 and HeLa cell line to $\gamma-radiation$, such as 4Gy 4hr. We found that exposure to $\gamma-ray$ alters by at least a $log_2$ factor of 1.0 the expression of known genes. Of the 27 genes affected by irradiation, 11 are down- regulated in MCF-7 cells and 2 genes induced by radiation,15 are repressed in HeLa cells. Many genes were involved in known damage- response pathways for cell cycling, transcription factor and cellular signaling response. However, in MCF-7 cells, we observed gene expression pattern in chromatin, apoptosis, stress, differentiation, cytokine, metabolism, ribosome and calcium. In HeLa cells, it showed clearly the expression changes in adhesion and migration, lysosome, brain, genome instability and translation. These insights reveal new therapy directions for studying the human carcinoma cell response to radiation.

The purpose of this study was to re-interpret the traditional patterns in modern point of view and connect them to the apparel textile design to use them widely in our real life. For this, a documentary research on the traditional patterns and arabesque patterns was made first, and then, through the manual and photoshop workings, two apparel textile designs were suggested. As a result, the followings were acquired: First, the arabesque pattern, which is a traditional pattern of Korea, has a continuous life power and a natural formative characteristics. In its pattern, there is an abundant possibility of change. So, it has a wide usability regardless of time and space. As the symbolic image of the arabesque pattern is connected with the instinctive beauty sense of human beings, it has shown the more adhesive affinity that any other materials. Second, two kinds of textile design were suggested. The motif of work 1, "Fragrance of Woman," was the richness and the harmony, and so a lotus arabesque pattern was selected to present its concept, "Classic Elegance." The expression technique was to use a manual work and cloths to make it a voluminous one. The motif of work 2, "Green Field" was to show the clean beauty with a lotus arabesque pattern. Its concept was the "Natural Elegance," and the expression technique was to repeat the motif by using the Adobe Photoshop to complete the work.

As a member of a subclass of immunophilins, it is controversial that FKBP38 acts an upstream regulator of mTOR signaling pathway, which control the process of cell-growth, proliferation and differentiation. In order to explore the relationship between FKBP38 and mTOR in the Cashmere goat (Capra hircus) cells, a full-length cDNA was cloned (GenBank accession number JF714970) and expression pattern was analyzed. The cloned FKBP38 gene is 1,248 bp in length, containing an open reading frame (ORF) from nucleotide 13 to 1,248 which encodes 411 amino acids, and 12 nucleotides in front of the initiation codon. The full cDNA sequence shares 98% identity with cattle, 94% with horse and 90% with human. The putative amino acid sequence shows the higher homology which is 98%, 97% and 94%, correspondingly. The bioinformatics analysis showed that FKBP38 contained a FKBP_C domain, two TPR domains and a TM domain. Psite analysis suggested that the ORF encoding protein contained a leucine-zipper pattern and a Prenyl group binding site (CAAX box). Tissue-specific expression analysis was performed by semi-quantitative RT-PCR and showed that the FKBP38 expression was detected in all the tested tissues and the highest level of mRNA accumulation was detected in testis, suggesting that FKBP38 plays an important role in goat cells.

The placenta is an extraembryonic tissue that is formed between mother and fetus and mediates delivery of nutrients and oxygen from the mother to the fetus. Because of its essential role in sustaining the growth of the fetus during gestation, defects in its development and function frequently result in fetal growth retardation or intrauterine death, depending on its severity. Vertebrate Hox genes are well known transcription factors that are essential for the proper organization of the body plan during embryogenesis. However, certain Hox genes have been known to be expressed in placenta, implying that Hox genes not only play a crucial role during embryonic patterning but also play an important role in placental development. So far, there has been no report that shows the expression pattern of the whole Hox genes during placentation. In this study, therefore, we investigated the Hox gene expression pattern in mouse placenta, from day 10.5 to 18.5 of gestation using real-time RT-PCR method. In general, the 5' posterior Hox genes were expressed more in the developing placenta compared to the 3' Hox genes. Statistical analysis revealed that the expression of 15 Hox genes (Hoxa9, -a11, -a13/ -b8, -b9/ -c6, -c9, -c13/ -d1, -d3, -d8, -d9, -d10, -d11, -d12) were significantly changed in the course of gestation. The majority of these genes showed highest expression at gestational day 10.5, suggesting their possible role in the early stage during placental development.
