  • This paper introduces a smart mirror technology that recognizes a person's facial expressions through image classification among several artificial intelligence technologies and presents them in a mirror. 5 types of facial expression images are trained through artificial intelligence. When someone looks at the smart mirror, the mirror recognizes my expression and shows the recognized result in the mirror. The dataset fer2013 provided by kaggle used the faces of several people to be separated by facial expressions. For image classification, the network structure is trained using convolution neural network (CNN). The face is recognized and presented on the screen in the smart mirror with the embedded board such as Raspberry Pi4.

  • Many hardware-based regular expression matching architectures have been proposed for high-performance matching. In particular, regular expression processors, which perform pattern matching by treating the regular expressions as the instruction sequence like general purpose processors, have been proposed. After instruction sequence and data are provided in the instruction memory and data memory, respectively, a regular expression processor can perform pattern matching. To use a regular expression processor as a coprocessor, we need the host interface to transfer the instruction and data into the memory of a regular expression processor. In this paper, we design and implement the host interface between a host and a regular expression processor in the DE1-SoC board and the application program interface. We verify the operations of the host interface and a regular expression processor by executing the application programs which perform pattern matching using the application program interface.

  • FRBR(Functional Requirements for Bibliographic Records) provides a structured conceptual model for relating the data which are recorded in bibliographic records to identify information resources. FRBR has 4 bibliographic entities - the work, expression, manifestation, and item - in its conceptual model. In this paper, the difference in the 'work' conception between FRBR and international standard numbers is examined Consequently, the following points are observed: (1) The ISBN, ISSN, and ISMN identify manifestation level, as they refer to the physical expression of a work. The IARN, ISRC, and ISAN identify expression level, irrespective of its manifestation. The ISWC and ISTC identify work level - the unique artistic creation, whatever its expression or manifestation is. (2) ISWC and ISTC does not use the word 'work' in the same way as FRBR does. I think that the differences in meanings of the two usages 'work' come from the different positions to information resources.

  • 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.

  • Though hydrogen peroxide ($H_2O_2$) causes a deleterious effect to cells with its reactive oxygen species resulting in cell death, S-allyl cysteine (SAC, a bioactive organosulfur compound of aged garlic extract) has been known to have a cytoprotective effect. Few reported profiles of gene expression of $H_2O_2$ and SAC treated human cord blood derived mesenchymal stem cells (MSC). This study revealed changes in the profile of twenty-one genes grouped by oxidative stress, antioxidant, cell death, anti-apoptosis and anti-aging by quantitative real time PCR. A concentration of $100{\mu}M$ of SAC or $50{\mu}M$ of $H_2O_2$ was applied to MSC which show moderate growth and apoptosis pattern. $H_2O_2$ treatment enhanced expression of eleven genes out of twenty-one genes compared with that of control group, on the contrary SAC suppressed expression of eighteen genes out of twenty-one genes except C ros oncogene. SAC decreased expression of oxidative stress genes such as SOD1, CAT and GPX. These results seemed consistent with reports which elucidated over-expression of NF-${\kappa}$B by $H_2O_2$, and suppression of it by SAC. This study will confer basic information for further experiments regarding the effects of SAC on gene levels.

  • The expression of CD44v is known as a marker of cancer progression and its metastasis in colorectal cancer. It has been known that CD44 variant containing sequences encoded by exon 11 (v6) confer metastatic potential to human colorectal cancer cells. The role of CD44 standard (CD44s) and CD44v6 in colorectal cancer was investigated in this study by immunohistochemical staining of the primary tumors obtained from the colorectal cancer patients. Immunohistochemical staining was performed in 40 patients with colorectal cancer who underwent curative surgery at Keimyung University hospital. The expression CD44s and CD44v6 was observed in 24/40 (60%) and 13/40 (32.5%) respectively. The expression of CD44v6 had correlation with TNM stage (P<0.05), however CD44s had not any correlation with clinicopathological parameters. These results suggest that CD44v6 expression may give an information for tumor progression than decreased expression of CD44s in colorectal cancer cells.

  • With development of digital technology and build-up of global network in the 21st century, Korea has recklessly accepted Western information and culture in recent years, thus causing damages to out identity. In the situation, restoration and development of traditions in a modern way will contribute to the creation of contemporary interiors. This study has analyzed and assessed the process through which traditional decorative elements have applied to contemporary interior decorations over the past ten years with a view to identify the trend of expressing traditional elements in comtemporary interiors. Designs that have applied traditional elements in a transfigure expression method amounted to 77 pieces, accounting for $43\%$ of the total investigated 178 designs, which was followed by 48 designs ($27\%$) of metaphor expression method and 39 designs ($22\%$) of symbol expression method, which express the tradition as interpreted by the designer. Designs that have adopted direct expression method amounted to no more than 14 pieces, accounting only for $8\%$ of the total designs. This result suggests that transformative, metaphoric and symbolic expressions that simplify or transform the original forms we more frequently used In the applications of traditional elements to modern interiors rather than directive expression that reproduces the original form as it was.

  • Uterine cells carry out proliferation and differentiation for preparation the embryonic implantation during pregnancy. Therefore regulation of the cell proliferation is an essential step for uterine preparation, but there is not much information about the proliferation related genes in pregnant uterus. To identify these implantation specific genes, a PCR-select cDNA subtraction method was employed and got a few genes. One of the identified genes is a novel gene encoding oral tumor suppressor doc-1. To detect the doc-1 expression on the pregnant uterus, dot blotting, RT-PCR, and in situ hybridization were employed. Dot blotting revealed that doc-1 mRNA expression increase after implantation. During normal pregnancy, doc-1 mRNA expression was detected as early as day 1 of pregnancy with RT-PCR. Its expression was increased about 15 times after embryonic implantation. doc-1 transcript was localized in luminal epithelial cells but it was very faint during preimplantation. After starting the implantation, it localized in the stromal cells; heightened expression of doc-1 correlates with intense stromal cell proliferation surrounding the implanting blastocyst on day 6 morning. However in the decidualized cells, the intensity of localized doc-1 mRNA was weak. From those results, it is revealed that doc-1 express at pregnant uterus of the mouse. In addition it is suggested that doc-1 is the gene regulating the proliferation of the luminal epithelial cells and stromal cells during early implantation and decidualization.

  • This paper devices a facial expression recognition method robust to overfitting using 2D-DCT and EHMM algorithm. In particular, this paper achieves enhanced recognition performance by setting up a large window size for 2D-DCT feature extraction and extracting the observation vectors of EHMM. The experimental results on the CK facial expression database and the JAFFE facial expression database showed that the facial expression recognition accuracy was improved according as window size is large. Also, the proposed method revealed the recognition accuracy of 87.79% and showed enhanced recognition performance ranging from 46.01% to 50.05% in comparison to previous approaches based on histogram feature, when CK database is employed for training and JAFFE database is used to test the recognition accuracy.
