This article is to present that the research on the Mudang Gut Chum should be within the context of the performance of Mudang Gut and examines its meanings and implications with focus on Seoul Mudang Gut Chum and Hwanghae-do Mudang Gut Chum. Seoul and Hwanghae-do Mudang Gut Chums do not exist in the form of simple dance or movement. They feature continuity while serving the function of revealing the existence of spirit and sometimes show the process of the spirit joining the Gut ritual, which means that the Mudang Gut Chum should not be understood as the dance itself only. Instead, care attention should be paid to the status of the tune of Gut where the dance is placed, relationship between the gut and the spirit, and the flow of narrativity. Also, the Mudang Gut Chum has a lot to do with the tune. Looking at the Mudang Gut Chum simply focusing on dancing steps, and the movement of feet and/or hands fails to gain an accurate understanding of the fundamentals of the Mudang Gut Chum. Closely connected to the tune, which is also associated with the grade of the spirit, the dance shows a variety of performances conducted by entering the Gut ritual of the spirit. In that respect, complex views on the Mudang Gut Chum are required. The same applies to the hereditary shaman Mudang Gut as well. The Korean Mudang Gut Chum has a slight difference between the Gangshinmu gut and the hereditary gut but is in basically the same aspect. The Gut Chum holds its meaning in the flow of gutgeori (tune or dance performed during exorcism, a shaman song) and delivers its own meaning in connection with the tune. It is definitely meaningful to focus on the individual movements of a dancing shaman but one should be able to derive the network of meanings that such movements have within the performance of the gutgeori, which means that intensive studies on the field performance and circumstances should be completed before studying the Mudang Gut Chum. In addition, the Mudang Gut Chum discloses the characteristics of the performance group. The Mudang Gut Chum exists in a complex manner. With respects to the status of the spirit, it shows the characteristics of the performance group. It represents the progress of Gut while closely connected with the tune. Therefore, the way of describing the Mudang Gut Chum should be far more than just simply keeping the dance notations. With this in mind, one should investigate and record the Mudang Gut Chum.

This study was performed to develop a suitable nutrient solution for standard rose substrate culture in a closed hydroponic system. 1/4, 1/2, 2/3 and 1 strength of the nutrient solution made by Japan National Institute of Vegetable and Tea Science (JNIVT) were supplied. The photosynthesis rate, quality and growth of cut flower were higher in the 1/2 and 2/3 strength of nutrient solution during high and low temperature period. Based on the above results, optimum nutrient solutions (UOS) were composed by nutrientwater (n/w) absorption ratio with 1/2S ($NO_{3^-}N$ 6.8, $NH_{4^-}N$ 0.7, $PO_{4^-}P$ 2.0, K 3.8, Ca 3.0, Mg 1.2, $SO_{4^-}S$ $1.2me{\cdot}L^{-1}$) at high temperature season and 2/3($NO_{3^-}N$ 9.7, $NH_{4^-}N$ 0.8, $PO_{4^-}P$ 2.2, K 5.0, Ca 3.9, Mg 1.5, $SO_{4^-}S$ $1.5me{\cdot}L^{-1}$) at low temperature season. The results of suitability examination showed that the EC level in newly composed nutrient solution (UOS) was more stable than other nutrient solutions due to its large amount of calcium and potassium. The growth of cut flower cultivated with UOS was higher than those of other nutrient solutions. Especially, the yield of cut flowers in UOS nutrient solution increased 1.4 times than that of other nutrient solution treatments. Consequently, the new nutrient solution investigated in this experiment was suitable for rose cultivation in a closed hydroponic system.

The purpose of this study is to examine the meaning of learning methods for education to transmit the items designated as intangible cultural heritages focusing on Seoul-gut. Recently, as the Act on the Preservation and Promotion of Intangible Cultural Heritages was promulgated, 'the archetype' instead of 'the prototype' has become highlighted as a crucial axis for transmission. Although there are some controversies over the definition of the archetype among scholars, it is now possible for transmitters to make use of transformations rather freely being freed from strict orientation to the prototype to follow some fixed frame. Examining learning methods used in education to transmit mudang-gut, one of the items designated as intangible cultural heritages, however, this author has found that the prototype is still emphasized or in the center of learning instead. Presenting learning methods employed for Hwanghaedopyeongsansonoreum-gut of a national intangible cultural heritage, Namijanggunsadang-gut of Seoul Special City's intangible cultural heritage, and Bonghwasandodang-gut as examples, this researcher intends to reveal the reality. In the recent situation that education centering around academies is being widely spread to transmit mudang-gut, setting forth the designation of some of the items as intangible cultural heritages, they are publishing articles on newspaper as an advertisement to encourage learning about mudang-gut. Responding to the advertisement, there are more and more shamans intending to learn mudang-gut coming to the society for preserving items designated as intangible cultural heritages. They can, of course, perform mudang-gut on their own but come to learn it as there is no fixed or definite system for it. Even though the concept of the archetype was introduced, as now it is possible to learn the fixed frame through learning about the prototype regarding the item of mudang-gut as an intangible cultural heritage, those involved in shamanism are coming to it more and more. As transmitting the prototype rather deteriorated the liveliness of gut, those involved in shamanism are coming to it to learn about gut thinking that it is where they can learn the basic frame and also acquire more detailed knowledge about shamanism. Therefore, it is needed for the item of mudang-gut designated as an intangible cultural heritage to accept the aspects of change and develop new methods of education to transmit intangible cultural heritages.

The purpose of this study was to develop a new fermented product (named as Cheonggeumjang) using Sigumjang, Cheonggukjang and Oak mushroom. This study was conducted to evaluate the effects of Sigumjang, Cheonggukjang, and Cheonggeumjang, which were mixed in a different ratio as A (Sigumjang: Cheonggukjang = 1:2), B (Sigumjang: Cheonggukjang = 1:1) and C (Sigumjang: Cheonggukjang = 2 : 1). Then, the functions and physicochemical properties of products were investigated. We found that the crude protein content in Cheonggeumjang was higher than in Sigumjang whereas fat and calories content was less than that of Cheonggukjang. Free sugar content in Cheonggeumjang C 5.8681 g/100g was the highest. Moroever, Cheonggeumjang C and Sigumjang has an antioxidant activities. The electron donating capacity, SOD like activity and the inhibitory effect on xanthine oxidase of these two were significantly high than other group. Fat rancidity is promoted in the presence of metal ion, Cheonggeumjang group has higher inhibitory effect on $Fe^{2+}$ion than on $Cu^{2+}$ ion. The rancidity of fat is also increased by reactive oxygens species, Cheonggeumjang group inhibited $H_2O_2$ in higher extent than $KO_2$. Also, ${\alpha}$-glucosidase inhibition activity of Cheonggeumjang C in all of the concentrations (300 ppm, 500 ppm and 700 ppm) is higher than other groups. In sensory evaluation, Cheonggeumjang C groups is ranked significantly higher than the other groups while considering color, flavor, taste and the overall acceptability. Taken together, the results of this study suggest that Cheonggeumjang is best ingredient for increasing the consumer acceptability and functionality.

Background: Epigallocatechin-3-gallate (EGCG) is the major catechin in green tea, and has shown antiproliferative, antiangiogenic, antimetastatic and cell cycle pertubation activity in various tumor models. Hypoxia can be induced because angiogenesis is insufficient for highly proliferating cancer. Hypoxia-inducible factor-1$\alpha$ (HIF-1$\alpha$) and its downstream target, vascular endothelial growth factor (VEGF), are important for angiogenesis, tumor growth and metastasis. The aim of this study was to determine how hypoxia could cause changes in the cellular phenomena and microenvironment in a non-small cell culture system and to examine the effects of EGCG on a HIF-1$\alpha$ and VEGF in A549 cell line. Methods: A549 cells, a non-small cell lung cancer cell line, were cultured with DMEM and 10% fetal bovine serum. A decrease in oxygen tension was induced using a hypoxia microchamber and a $CO_2-N_2$ gas mixture. Gas analysis and a MTT assay were performed. The A549 cells were treated with EGCG (0, 12.5, 25, 50 ${\mu}mol/L$), and then examined by real-time-PCR analysis of HIF-1$\alpha$, VEGF, and $\beta$-actin mRNA. Results: Hypoxia reduced the proliferation of A549 cells from normoxic conditions. EGCG inhibited HIF-1$\alpha$ transcription in A549 cells in a dose-dependent manner. Compared to HIF-1$\alpha$, VEGF was not inhibited by EGCG. Conclusion: HIF-1$\alpha$ can be inhibited by EGCG. This suggests that targeting HIF-1$\alpha$ with a EGCG treatment may have therapeutic potential in non-small cell lung cancers.

Purpose: Several studies have proven that EGCG, the primary green tea catechin, and glucosamine-6-phosphate (PGlc) reduce triglyceride contents in 3T3-L1 adipocytes. The objective of this study is to evaluate the combination effect of EGCG and PGlc on decline of accumulated fat in differentiated 3T3-L1 adipocytes. Methods: EGCG and PGlc were administered for 6 day for differentiation of 3T3-L1 adipocytes. Cell viability was measured using the CCK assay kit. In addition, TG accumulation in culture 3T3-L1 adipocytes was investigated by Oil Red O staining. We examined the expres-sion level of several genes and proteins associated with adipogenesis and lipolysis using real-time RT-PCR and Western blot analysis. A flow cytometer Calibar was used to assess the effect of EGCG and PGluco on cell-cycle progression of differentiating 3T3-L1 cells. Results: Intracelluar lipid accumulation was significantly decreased by combination treatment with EGCG $60{\mu}M$ and PGlc $200{\mu}g/m$ compared with control and EGCG treatment alone. In addition, use of combination treatment resulted in directly decreased expression of $PPAR{\gamma}$, $C/EBP{\alpha}$, and SREBP1. In addition, it inhibited adipocyte differentiation and adipogenesis through downstream regulation of adipogenic target genes such as FAS, ACSL1, and LPL, and the inhibitory action of EGCG and PGlc was found to inhibit the mitotic clonal expansion (MCE) process as evidenced by impaired cell cycle entry into S phase and the S to G2/M phase transition of confluent cells and levels of cell cycle regulating proteins such as cyclin A and CDK2. Conclusion: Combination treatment of EGCG and PGlc inhibited adipocyte differentiation through decreased expression of genes related to adipogenesis and adipogenic and cell cycle arrest in early stage of adipocyte differentiation.
