  • Modern ceramics art has various expression techniques. Among them, the digitization of modern society has led to the development of the transfer printing technique, and the technique of transfer printing has been utilized as medium of expression of modern ceramics. However, the transfer printing technique is merely uniform and does not give enough information to utilize the artistic expression of the craftsmen using the technique of decal rather than actively utilizing it in the field for mass production. Therefore. In this paper, we will examine the works of contemporary pottery artists who understand the meaning of the transfer printing technique and express the artist 's personality and artistry with transfer printing technique, so that the transfer printing technique can enhance the aesthetic and artistic effect of ceramic art as the expression medium of modern ceramics. We want to lay the foundations for a higher value-added industry.

  • Modern ceramics is exploring the expansion of the area with various expression techniques. The silhouette technique among various expressive decoration techniques is a representative expression technique of object form expression. This emphasizes the outline of the form and expresses it and omits the inner form. It gives simplicity and intensity, and awakens aesthetic sensibility and imagination. Therefore, the researcher designed the material related to the core image of the story by designing it as a silhouette technique by using the "Acorn Story" as a subject and then making the transfer paper by using the vector graphic. The transferred paper was expressed on a ceramic plate by transferring technique. Therefore, I hope that this research, beyond the merely decorative function of ceramic expression, will become a ceramic design that will awaken imagination and aesthetic sensibility in digital information age.

  • 전사체(transcript)는 유전자로부터 전사된 DNA 시퀀스 코드를 말한다. 전사체(transcript)의 발현된 형태에 따라 생성되는 단백질의 형태 역시 달라지므로 전사체 모델의 형태는 중요한 의미를 가지며 특정 위치의 전사체가 정상과 다르게 모델이 변할 경우 심각한 경우에는 유전자 질병에 노출될 수 있다. 현재 실험체에 대한 전사체 모형은 SpliceGrapher, Cufflinks와 같은 상용화된 도구들을 사용하여 얻을 수 있다. 하지만 이런 도구 간의 결과 값 및 어노테이션 정보와 결과 값 간의 유사도 비교를 위한 방법론은 현재 알려진 바 없다. 대신 전사체 비교를 위해 모형 간의 차이를 눈으로 하나씩 비교하거나 전사체 위치를 이용한 산수 값을 이용한다. 본 논문에서는 전사체 모형 간의 유사도를 비교하기 위한 방법론을 제시하고 Homo sapiens grch37 어노테이션 파일과 SRR387514 실험 데이터 간의 유사도를 제시한 방법론을 이용하여 측정한 결과 값을 분석하였다.

  • This paper presents an acoustic model transform method using untranscribed speech database for improved speech recognition. In the presented model transform method, an adapted GMM is obtained by employing the conventional adaptation method, and the most similar Gaussian component is selected from the adapted GMM. The bias vector between the mean vectors of the clean GMM and the adapted GMM is used for updating the mean vector of HMM. The presented GAMT combined with MAP or MLLR brings improved speech recognition performance in car noise and speech babble conditions, compared to singly-used MAP or MLLR respectively. The experimental results show that the presented model transform method effectively utilizes untranscribed speech database for acoustic model adaptation in order to increase speech recognition accuracy.

  • Located on the upstream of a gene, the promoter region that plays a very important role in the control of gene expression as a signal part has various binding sites for transcription factors. These binding sites are present in various parts of the promoter region and assume an aspect of highly conserved consensus sequence pattern. This paper deals with the introductions of search methods for consensus pattern, including Wataru method, EM algorithm, MEME algorithm, Genetic algorithm and Phylogenetic Footprinting method, and intends to give future prospects of research on this field.

  • Objective: In the previous study, we complied the differentially expressed genes during early folliculogenesis. Objective of the present study was to identify downstream target genes of transcription factors (TFs) using bioinformatics for selecting the target TFs among the gene lists for further functional analysis. Materials & Methods: By using bioinformatics tools, constituent domains were identified from database searches using Gene Ontology, MGI, and Entrez Gene. Downstream target proteins/genes of each TF were identified from database searches using TF database ($TRANSFAC^{(R)}$ 6.0) and eukaryotic promoter database (EPD). Results: DNA binding and trans-activation domains of all TFs listed previously were identified, and the list of downstream target proteins/genes was obtained from searches of TF database and promoter database. Based on the known function of identified downstream genes and the domains, 3 (HNF4, PPARg, and TBX2) out of 26 TFs were selected for further functional analysis. The genes of wee1-like protein kinase and p21WAF1 (cdk inhibitor) were identified as potential downstream target genes of HNF4 and TBX2, respectively. PPARg, through protein-protein interaction with other protein partners, acts as a transcription regulator of genes of EGFR, p21WAF1, cycD1, p53, and VEGF. Among the selected 3 TFs, further study is in progress for HNF4 and TBX2, since wee1-like protein kinase and cdk inhibitor may involved in regulating maturation promoting factor (MPF) activity during early folliculogenesis. Conclusions: Approach used in the present study, in silico analysis of downstream target genes, was useful for analyzing list of TFs obtained from high-throughput cDNA microarray study. To verify its binding and functions of the selected TFs in early folliculogenesis, EMSA and further relevant characterizations are under investigation.

  • 3C (chromatin conformation capture) is a technique to analyze chromatin organization in nuclei of eukaryotic cells. The procedure of 3C includes the formaldehyde treatment of cells to fix interactions between proteins and between proteins and DNA in chromatin, the digestion of fixed chromatin with restriction enzyme, and the ligation of fragmented DNA. The efficiency of DNA ligation represents proximity between DNA fragments in chromatin organization. Studies in the ${\beta}$-globin locus using 3C showed that the locus control region is in close proximity to the transcriptionally-active globin genes, indicating that chromatin organization has a role in transcriptional regulation of the genes. 3C has been advanced by combining with ChIP and genome-wide sequencing. This review presents the principle and procedure of the 3C technique, the chromatin organization of the ${\beta}$-globin locus explained by 3C, and advanced techniques based on 3C.
