The purpose of this study is verifying whether convergence does its role as a transfer medium in dance expression or not, finding the effect of convergence characteristics and confirming whether it would bring change and new creation in performance art or not. This study suggests that studies on convergence in dance are required in accordance with the trend of time. This study believes that convergence is a modern art expression method, which can maximize the artistic expression in dance work and it will play an important role in the advance of dance works. There are ongoing studies on convergence art genre by many creators; however, still academic study this matter is not sufficient. Therefore, it is believed that more studies on convergence genre from the viewpoint of human studies are required. Accordingly, this study took Blush, the dance art works of Wim Vandekeybus, as the subject of study because convergence is clearly visible in these works. It is possible to draw convergence from these works because the works attempt new creation and utilize image by accommodating other genre art in dance art. The convergence in these works maximizes the originality of choreography and expands the time and space of stage through various effects. In other words, it is possible to see that Wim Vandekeybus is doing new attempts in his dance works by experimental elements, which escaped from simple movement, and convergence appears in the works.

For increasing the competitiveness and efficiency of Korea's finance industry under the new e-finance paradigm, this paper compared the practical use of finance portal site' on service parts and stage between Korea and U.S.A.. The services which can be served from site are banking, mortgage and credit loan, stock, card, retirement tax, PFM(Personal Finance Management), EBPP(Electronic Bill Presentment and Payment) and Account Aggregation and so on. The stage of site can be divided as the information provide stage which only gives information about service parts, on-line transaction stage which real-time transaction is possibile and PFM services provide stage according to development process. As a result, the beginning of finance portal service in Korea was lated about 10years and more than it of U.S.A. So the development stage of domestic portal site is still staying in the first step and the providing services and contents or business model development parts are also in the same stage than U.S.A. Resides, Korea's sites mainly focus on their first service parts even though they recently aim internet finance portal, and provide not real time transaction but finance information. On the other hand, the U.S.A. site support substantially not only various on-line transactions but also distinctive personal services like PFM(Personal Finance Management), EBPP(Electronic Bill Presentment and Payment), Account Aggregation and Trans-account, brokerage, education center, mortgage loan, mutual fund, option, pension fund and IPOs and so on. Thus, the site of Korea need to establish real type of internet finance portal which provides one-stop services on every type of finance to customers in the real time and also require the strategic integration among finance institutions. The next turn, they need to build information system and education center to give best satisfaction to customers and acquire customer information and marker environment changes and need to provide distinctive services to quality customers throughout database from this. Also the site should provide various type of banking services which refereed above like PEM, EBPP and education center etc, and the government of Korea should support the building of IT infrastructure to Physical, legal, systematic, sociocultural, technical and human resource sections. This paper provided the future movement direction of the domestic finance portal through comparison and analysis on the practical use of it between Korea and U.S.A. and also wanted to contribute for developing and reading of Korea finance portal in the new era of the finance paradigm.

The genres of fantastic of Korean films created in the 90s are diverse. The fantastics of these works are not manifested only in 'Ghosts' movies. For example, If the film Mystery Of The Cube, which is based on the mystery of Lee Sang, has a story of structuralist fantasy, we can say that a movie like Tell Me Something has a psychologically conventional fantastic. This study examines the fantastic of contemporary Korean films through 'completion of allegory based on realism'. For this, we borrows the fantastic concept of Etienne Souriau. In some films, fantastics can be found directly in the developing nature. In this case, the human being who justifies their domination of nature by upgrading their position as the objectifying subject of nature becomes 'alienated' in return. The notion of this alienation in film narratives is often revealed through allegories, particularly in the manifestation of fantasy by Étienne Souriau in the early 'personal experience'. Kim kiduk's film is a representative example of allegorizing elements of society through individual experience. Focusing on Kim Giduk's Bad Guy, this essay analyzes the process in which fantastic films of Korea in the 90s build up aesthetic fantastic through imitation of society.

We investigated the effects of skin hydration and anti-irritation of exopolysaceharide (GF-glucan) produced from submerged culture of Grifola frondosa. The moisturizing effects and trans-epidermal water loss (TEWL) of GF-glucan in cosmetic products (O/W emulsion) were clinically studied. GF-glucan showed good skin hydration effects when compared with sodium hyaluronate which is a commonly using moisturizer. The skin protective effects of GF-glucan against sodium lauryl sulfate (SLS) were also found. Twice a day application of the CF-glucan to skin reduced local inflammation remarkably. Irritant reactions were assessed by various aspects of skin function, erythema (skin color reflectance), hydration (electrical capacitance) and TEWL. In the human skin test, 5-day treatment of the GF-glucan was found to reduce SLS-induced skin erythema and Improve bier regeneration. Taken all together, GF-glucan should be a very useful cosmetic ingredient, as a moisturizer, and a protecting agent for various skin irritations.

Objectives : Ojeoksan, originally recorded in an ancient Korean medicinal book named "Donguibogam" and has been used for the treatment of circulation disorder of blood which was called blood accumulation (血積) in Korean medicine. Therefore, this study was carried out to investigate the beneficial effect of OJS on vascular inflammation in HUVECs. Methods : We evaluated the effect of OJS on the expression of cell adhesion molecules and protective role in HUVEC stimulated by TNF-${\alpha}$ by using Western blot. Results : Pretreatment with OJS decreased the adhesion of HL-60 cells to TNF-${\alpha}$-induced HUVEC. OJS suppressed TNF-${\alpha}$-induced expression level of cell adhesion molecules such as intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1(VCAM-1), and endothelial cell selectin (E-selectin). Moreover, OJS significantly decreased TNF-${\alpha}$-induced production of intracellular reactive oxygen species (ROS); and inhibited the phosphorylation of $I{\kappa}B-{\alpha}$ in the cytoplasm compared to the experimental group. Pretreatment with OJS inhibited the trans-location of NF-${\kappa}B$ p65 to the nucleus. OJS also inhibited phosphorylation of MAPKs compared to the experimental group. OJS significantly increased the protein expression of Nrf2 and HO-1. Conclusions : Ojeoksan has a protective effect on vascular inflammation, and might be a potential therapeutic agent for early atherosclerosis.

Peroxiredoxin 6 (Prx 6) is a member of the thiol-specific antioxidant protein family, which may play a role in protection against oxidative stress and in regulating phospholipid turnover. The aim of this study was to determine whether a human Prx 6/Luc vector was stably expressed and responded to antioxidants in a lung cell line (NCI-H460). To achieve this, the luciferase signal, hPrx 6 mRNA expression, and superoxide dismutase (SOD) activity were measured in transfectants with a hPrx 6/Luc plasmid after treatment with four antioxidant extracts, including Korea white ginseng (KWG), Korea red ginseng (KRG), Liriope platyphylla (LP), and red Liriope platyphylla (RLP). First, the hPrx 6/Luc plasmid was successfully constructed with DNA fragments of human Prx 6 promoter, amplified by PCR using genomic DNA isolated from NCI-H460 cells, and cloned into the pTransLucent reporter vector. The orientation and sequencing of the hPrx 6/Luc plasmid were identified with restriction enzyme and automatic sequencing. A luciferase assay revealed significant enhancement of luciferase activity in the four treatment groups compared with a vehicle-treated group, although the ratio of the increase was different within each group. The KRG- and LP-treated groups showed higher activity than the KWG- and RLP-treated groups. Furthermore, the luciferase activity against RLP occurred roughly in a dose-dependent manner. However, the level of endogenous hPrx 6 mRNA did not change in any group treated with the four extracts. The SOD activity was in agreement with the luciferase activity. Therefore, these results indicate that the hPrx 6/Luc vector system may successfully express and respond to antioxidant compounds in NCI-H460 cells. The data also suggest that the Prx 6/Luc vector system may be effectively applied in screening the response of hPrx 6 to antioxidant compounds in transgenic mice.

Background : Metabolic cooperation via gap junctional intercellular communication (GJIC) is an important mechanism of the bystander effect in gene therapy using the Herpes Simplex Virus thymidine kinase/ganciclovir (HSVtk) "prodrug" system. Since retinoids have been reported to increase GJIC by induction of connexin 43 expression, we hyporthesized that treatment of tumor cells with retinoic acid could augment the bystander effect of the HSVtk/GCV system and result in improved tumor cell killing by enhancing GJIC. Methods : We transferred HSVtk gene to SKHep-J cell line that does not express connexin43, and also transferred the gene to human and murine mesothelioma cell lines that express connexin43. We verified that retinoic acid enhanced GJIC utilizing a functional double-dye transfer study and evaluated the effects of retinoic acid on the growth rate of tumor cells. We then tested the effects of retinoic acid on bystander-mediated cell killing. Results : Addition of all-trans retinoic acid (RA) increased GJIC in cell lines expressing connexin 43 and was asspciated with more efficient in vitro bystander killing in cells transduced with HSVtk via adenoviral and retroviral vectors. In contrast, there was no increase in the efficiency of the bystander effect after exposure to RA in a cell line which had no delectable connexin 43. Conclusion : These results provide evidence that retinoids can augment the efficiency of cell killing with the HSVtk/GCV system by enhancing bystander effect and may thus be a promising new approach to improve responses in gene therapy utilizing the HSVtk system to treat tumors.

The purpose of this study was to evaluate the effects of fluoride relasing orthodontic sealant on the shear bond strength of light-and chemical-cured orthodontic rosins, to compare the shear bond strenth with light-and chemical-cured orthodontic resins, and to identify the changes of shear bond strength by rebonding in vitro. The brackets were divided into eight groups. Each group of metal brackets had different bonding mechanisms with adhesives. Group A : Transbond only Group B : Mono-Lok 2 only Group C : Light cured FluoroBond+Transbond Group D : Light cured FluoroBond+Mono-Lok 2 Group E : Transbond only(rebonded) Group F : Nomo-Lok 2 only(rebonded) Group G : Light cured FluoroBond+Transbond(rebonded) Group H : Light cured FluoroBond+Mono-Lok 2(rebonded) 65 extracted human premolars were prepared for bonding and 65 metal brackets for each group were bonded to prepared enamel surfaces of buccal surfaces as the above prescription. 24 hours bonding after, the Instron universal testing machine was used to test the shear bond strength of metal brackets to enamel. After debonding, same kind of metal brackets for each group were rebonded to prepared enamel surfaces of buccal surfaces to test the shear bond strength at the rebonding to enamel. Statistical analysis of the data was carried out Student's t-test ANOVA test, and Scheffe test using $SPSS/PC^+$ The results were as follows : 1. The order of shear bond strength was Group B(11.84MPa), Group A(10.75MPa), Group, D(9.69MPa), and Group C(9.39MPa)in lst bonded groups. 2. The order of shear bond strength was Group E(7.40MPa), Group G(6.48MPa), Group F(5.89MPa), and Group H(5.15MPa) in rebonded groups. 3. The shear bond strength of chemical cured orthodontic rosins had higher than that of light-cured orthodontic resins in all groups, but there was no statistical significance between groups(P>0.05). 4. In rebonded groups, the shear bond strength of light cured orthodontic rosins had higher than that of chemical cured orthodontic resins, but there was no statistical significance between groups(P>0.05). 5. The shear bond strength of all rebonded groups progressively decreased than that of 1st bonded groups, and there was statistical significance between groups(p<0.05, p<0.001).

The T-type amino acid transporter 1 (TATI) is a Na$^{+}$-independent amino acid transporter which selectively trans- ports aromatic amino acids subserving the amino acid transport system T. To understand the transport properties of aromatic amino acids by human TAT1 (hTATl ), we have examined the hTATl -mediated aromatic amino acid transports using a Xenopus laeuis oocyte expression system. When expressed in Xenopin laeuis oocytes, hTATl induced L- [$^{14}$ C]tryptophan transport which was not dependent on Na$^{+}$ or Cl$^{[-10]}$ in the medium. Uptake was time-dependent and exhibited a linear dependence on incubation time up to 30 min. The L- ($^{14}$ C)tryptophan uptake was highly inhibited by L-isomers of tryptophan, tyrosine and phenylalanine, whereas other L-amino acids did not inhibit hTATl -mediated L- ($^{14}$ C)tryptophan uptake. The hTATl induced the relatively low-affinity transport of aromatic amino acids such as L- ($^{14}$ C)tryptophan, L- ($^{14}$ C)tyrosine and L- ($^{14}$ C)phenylalanine (Km values: 450～750 $\mu$M), consistent with the properties of classical amino acid transport system T. The L- ($^{14}$ C)tryptophan uptake did not show any remarkable pH dependence within the pH range of 5.5 to 8.5. The time-dependent efflux of L- ($^{14}$ C)tryptophan was detected from the oocytes expressing hTATl, which was not affected by the presence or absence of L-tryptophan in the extracellular medium, indicating that hTATl-mediated transport is due to the facilitated diffusion. Expression of hTATl in Xenopu laevis oocytes induced the transport of tryptophan, tyrosine and phenylalanine, indicating that hTATl is a transporter subserving system T These results suggest that hTATl has essential roles in the absorption of aromatic amino acids from epithelial cells to the blood stream. Hecause hTATl is proposed to be crucial to the efficient absorption of aromatic amino acids from intestine and kidney, its defect such as blue diaper syndrome could be involved in the disruption of aromatic amino acid transport.ort.
