As an effort to improve the employment of graduates from fashion.related departments, this study purposed to develop a course that may contribute to a broader range of employment, focusing on CS, which has been overlooked by fashion.related departments, among various job categories in the fashion industry. In order to determine the necessity of the new course, we surveyed job categories that enrolled students wanted to have after graduation and graduates'opinions on and responses to the opening of the new course. In addition, for the efficient design of the course, this study extracted the practically applicable goals and contents of the course from basic theories in previous CS .related studies in the area of fashion studies and from interviews with field workers in related businesses. Through these multi.sided approaches, this study proposed a fashion CS course as a major applied subject with an hours' theory and two hours' practice classes, and suggested a weekly teaching plan of 15 weeks. This study is meaningful in that it expanded the scope and variety of employment for students of fashion.related departments, and developed a course that can be immediately applicable to any CS.related jobs. The results of this study are expected to expand work areas for graduates from fashion.related departments in the fashion industry.

The evolutionary course of the CsRn1 long-terminal-repeat (LTR) retrotransposon was predicted by conducting a phylogenetic analysis with its paralog LTR sequences. Based on the clustering patterns in the phylogenetic tree, multiple CsRn1 copies could be grouped into four subsets, which were shown to have different integration times. Their differential sequence divergences and heterogeneous integration patterns strongly suggested that these subsets appeared sequentially in the genome of C. sinensis. Members of recently expanding subset showed the lowest level of divergence in their L TR and reverse transcriptase gene sequences. They were also shown to be highly polymorphic among individual genomes of the trematode. The CsRn1 element exhibited a preference for repetitive, agenic chromosomal regions in terms of selecting integration targets. Our results suggested that CsRn1 might induce a considerable degree of intergenomic variation and, thereby, have influenced the evolution of the C. sinensis genome.

The hydrogenolysis of cellulose into polyols was examined over Pt/$Cs_xH_{3-x}PW_{12}O_{40}$ catalysts containing different Cs fractions. The surface area and Pt dispersion of Pt/$Cs_xH_{3-x}PW_{12}O_{40}$ catalysts were found to increase with Cs content. Similar polyol yields were obtained over Pt/$Cs_xH_{3-x}PW_{12}O_{40}$ catalysts irrespective of their Cs content. The catalytic activity of Pt/$Cs_xH_{3-x}PW_{12}O_{40}$ was comparable to that of Ni/W/SBA-15 and combined catalytic systems such as Pt/AC+$H_3PW_{12}O_{40}$ and Pt/AC + $Cs_{3.0}PW_{12}O_{40}$. Some polyanion species were found to leach from the Pt/$Cs_xH_{3-x}PW_{12}O_{40}$ catalyst during the course of the reaction.

The interaction of cyclosporine A (CsA), an immunosuppressant, with rat brain Kv1.5 (Kv1.5) channels, which were stably expressed in Chinese hamster ovary cells, was investigated using the whole-cell patch-clamp technique. CsA reversibly blocked Kv1.5 currents at +50 mV in a reversible concentrationdependent manner with an apparent $IC_{50}$ of 1.0μM. Other calcineurin inhibitors (cypermethrin, autoinhibitory peptide) had no effect on Kv1.5 and did not prevent the inhibitory effect of CsA. Fast application of CsA led to a rapid and reversible block of Kv1.5, and the onset time constants of the CsA-induced block were decreased in a concentration-dependent manner. The CsA-induced block of Kv1.5 channels was voltage-dependent, with a steep increase over the voltage range of channel opening. However, the block exhibited voltage independence over the voltage range in which channels were fully activated. The rate constants for association and dissociation of CsA were $7.0{\mu}M{-1}s^{-1}$ and $8.1s^{-1}$, respectively. CsA slowed the deactivation time course, resulting in a tail crossover phenomenon. Block of Kv1.5 by CsA was use-dependent. CsA also blocked Kv1.3 currents at +50 mV in a reversible concentration-dependent manner with an apparent $IC_{50}$ of $1.1{\mu}M$. The same effects of CsA on Kv1.3 were also observed in excised inside-out patches when applied to the internal surface of the membrane. The present results suggest that CsA acts directly on Kv1.5 currents as an open-channel blocker, independently of the effects of CsA on calcineurin activity.

In the course of immunoscreening of Clonorchis sinensis cDNA library, a cDNA CsRP12 containing a tandem repeat was isolated. The cDNA CsRP 12 encodes two putative peptides of open reading frames (ORFs) 1 and 2 (CsRP12-1 and -2). The repetitive region is composed of 15 repeats of 10 amino acids. Of the two putative peptides, CsRP12-1 was proline-rich and found to have homologues in several organisms. Recombinant proteins of the putative peptides were bacterially produced and purified by an affinity chromatography Recombinant CsRP12-1 protein was recognized by sera of clonorchiasis patients and experimental rabbits, but recombinant CsRP 12-2 was not. One of the putative peptide, CsRP12-1, is designated CsPRA, proline-rich antigen of C. sinensis. Both the C-termini of CsRP12-1 and -2 were bacterially produced and analysed to show no antigenicity. Recombinant CsPRA protein showed high sensitivity and specificity. In experimental rabbits, IgG antibodies to CsPRA was produced between 4 and 8 weeks after the infection and decreased thereafter over one you. These results indicate that CsPRA is equivalent to a natural protein and a useful antigenic protein for serodiagnosis of human clonorchiasis.

Mouse malignant T-lymphoma CS21 cells can grow when cocultured with CAl2 lymph node stromal cells, but they undergo apoptotic cell death with DNA fragmentation when separated from CA12 stromal cells. In the course of examining the effects of the soluble factor (s) secreted by CAl2 stromal cells on CS2l cell growth, we found that thiols including cysteine promoted CS2l cell growth. P388 cell growth was also promoted by various thiols. These results suggest that thiols including cysteine participate in CA12 and P388 cell growth.

Countries that considered importance of the quality management of higher education are strengthening through various systems and methods. Field of computer science also, they have constantly made efforts, such as constituting standards of curriculum for the management of the quality of higher education. If we know the priorities of the knowledge area mentioned in the standard of curriculum of computer science, we can give implications to the composition of the content system. Therefore, we derive the ranking based on base on CS2013 the lesson time number of Tier 1, Tier 2, Elective, and detail areas for content elements. As a result, the knowledge area with the highest priority was Software Development Fundamentals. The knowledge area is recommended as a beginner course in CS2013 because it is a basic element. The priorities of these areas may provide implications for future elementary and secondary informatics curriculum, higher liberal arts informatics curriculum, Informatics curriculum of teacher training agency.

Purpose: In this study, porous type I collagen scaffolds were cross-linked using dehydrothermal(DHT) treatment and/or 1-ethyl-3-(3-dimethyl aminopropyl) carbodiimide(EDC), in the presence and absence of chondroitin-6-sulfate(CS) and cultured autologous chondrocytes(Chondro) for cartilage regeneration. Methods: Cartilage defects were created in the proximal part of the ear of New Zealand rabbits. Four prepared types of scaffolds(n=4) were inserted. The groups included Chondro-Collagen-DHT(Group 1), Chondro- Collagen-DHT-EDC(Group 2), Chondro-CS-Collagen- DHT(Group 3), and Chondro-CS-Collagen-DHT-EDC (Group 4). Histomorphometric analysis and cartilage-specific gene expression of the reconstructed tissues were evaluated 4, 8, and 12 weeks after implantation. Results: EDC cross-linked groups 2 and 4 regenerated more cartilage than other groups. However, calcification was observed in the 4th week after implantation. CS did not increase chondrogenesis in all groups. Cartilage-specific type II collagen mRNA expression increased in the course of time in all groups.Conclusion: EDC cross-linking methods maintain the scaffold and promote extracellular matrix production of chondrocytes.

The United States (CS2013) and Japan (J07-CS) constitute a standard informatics curriculum that reflects a changing society at the level of higher education. This study analyzed the change of standard curriculum in the United States in order to provide implications for the standard composition of higher education curriculum in Korea. The subjects were composed based on the analysis of current status of university curriculum and content knowledge in Korea. As a result of the research, the Informatics curriculum in the United States has evolved into a curriculum reflecting the changing computing environment. The information curriculum of domestic colleges included only 52% of the knowledge area of CS2013. The purpose of this study is to provide an example of the composition of subjects based on the curriculum composition policy of Japan and to provide a basis for the curriculum composition without the standard informatics education course of the college in korea.

Purpose: Cyclosporine(CsA) is a potent immunosuppressant but the use of CsA is associated with various side effects, especially nephrotoxicity. In tile kidney, salt depletion activates tile renin-angiotensin-aldosteron(RAS) system and accentuates chronic CsA nephropathy. We postulate that angiotensin converting enzyme inhibitors(ACEI) can prevent chronic CsA nephropathy, since ACEI may inhibit this cascades. This study was aimed to assess the effect of ACEI on chronic cyclosporin nephropathy in salt depleted rats. Methods: 36 Fischer-344 rats were divided into 6 goups. Group I received normal salt diet(NSD). Group II received a low salt diet(LSD). Group III received CsA with a NSD. Group IV received CsA with a LSD. Group V received NSD+CsA with ACEI. Group VI received LSD+CsA with ACEI. Rats were sacrificed after six weeks and the glomerular filtration rate(GFR), serum sodium, potassium and whole blood cyclosporine levels were measured. Renal tissues me sampled for the observation of histological changes. Results: No differences in blood CsA level & serum sodium were found between groups during the course of this experiment. Serum potassium in group VI was significantly increased compared with group IV and V (P<0.05). In groups treated with CsA only and in those where CsA was combined with ACEI, GFR was found to be significantly more decreased in LSD than NSD, and GFR in group V was significantly decreased in comparison with group III (P<0.05). Renal histologic lesions associated with CsA which consisted of cortical interstitial fibrosis, tubular atrophy and hyalinization of arterioles were more severe in tile LSD group. But, no differences were observed between tile groups treated with CsA and ACEI, and the groups treated with only CsA. Conclusion: Salt depletion associated with the activation of the RAS system accentuated chronic CsA nephrotoxicity, but, ACEI could not reduce the functional and morphological changes of salt depleted kidneys, in which nephropathy can be exacerbated in spite of the blocking of the angiotensin II pathway. further studies are required to elucidate whether Am ameliorated the effect of salt-depleted CsA nephrotoxicity upon the effective renal blood flow.
