Athletic performance is an important criteria used for the selection of superior horses. However, little is known about exercise-related epigenetic processes in the horse. DNA methylation is a key mechanism for regulating gene expression in response to environmental changes. We carried out comparative genomic analysis of genome-wide DNA methylation profiles in the blood samples of two different thoroughbred horses before and after exercise by methylated-DNA immunoprecipitation sequencing (MeDIP-Seq). Differentially methylated regions (DMRs) in the pre-and post-exercise blood samples of superior and inferior horses were identified. Exercise altered the methylation patterns. After 30 min of exercise, 596 genes were hypomethy-lated and 715 genes were hypermethylated in the superior horse, whereas in the inferior horse, 868 genes were hypomethylated and 794 genes were hypermethylated. These genes were analyzed based on gene ontology (GO) annotations and the exercise-related pathway patterns in the two horses were compared. After exercise, gene regions related to cell division and adhesion were hypermethylated in the superior horse, whereas regions related to cell signaling and transport were hypermethylated in the inferior horse. Analysis of the distribution of methylated CpG islands confirmed the hypomethylation in the gene-body methylation regions after exercise. The methylation patterns of transposable elements also changed after exercise. Long interspersed nuclear elements (LINEs) showed abundance of DMRs. Collectively, our results serve as a basis to study exercise-based reprogramming of epigenetic traits.

The purpose of this study was to approach to the internal meanings included in the Happening and the culture of hippies, by analysing the basic mental conditions in the process of the Happening. And this study was composed of the concept and the development of Happening, the characteristics of the hippies that related in the midst of the happening's background, and the formativeness between these factors and hippies'fashion. Since the happening a genre of fine arts expression attended the New School for social research in New York in 1954, Allan Kaprow direct-influenced by John Cage used the word 'Hapening'first, practicing '18 Happenings in 6 parts'at the Rueben gallery in 1959. Kaprow's 18 Happenings was one of the earliest opportunities for a wider public to attend the live events that several artists had performed more privately for various friends. Despite the very different sensibilities and structures of artist's works, artists were all thrown together by the press under the general heading of 'Happening', following Kaprow's 18 Happenings. Being considered as the root of the Happening 'Expression of Sound'of John Cage was the discovery of the exisiting thing- the Happening. Most artists were to be deeply influenced by Cage's theories and attitudes-that is, his sympathy for Zen Buddihism and oriental philosophy-and by reports of the Black Mountain events. These events would directly reflect contemporary painting and stemmed from the Futurists, Dadaists and Surrealists. And Happening's development background was based on the culture of hippies. Swinging London had been under the sway of psychedelic drugs and utopian visions of 'hippie'wave sweeping in from Califonia. This wave, which affected solid middle-class youth first and formost, began in Haight Ashbury in San Francisco. Without dwelling on the hippie movement here, it is worth nothing that it resulted from the convergence of several undercurrents : consciousness-expending drugs, the anti-Vietnam war developments, the impact of English pop groups on American music and the rise of protest songs, and finally the beatnik tradition of non-conformism. Hippie culture and its pursuit of love, peace and psychedelia was the antitheses of 1960s main street fashion. The media gave everyone with long hair the label of 'hippie', but it was always a very loose collage of attitudes and styles. The rejection of sexual taboos was conveyed by the hippie's refusal to wear. Although the bold exposure of body raised controversies because it went against the existing moral values, it has a significant implications. Psychedelics brought mind-expansion and the possibillity that modern technology (light show, synthesized electronic sounds), new fabrics or colors, and LSD could be utilized to provide an escape route from the dreariness of modern life. During the 1960s, traditional costumes, many of which had never been seen outside their native regions, became sought after and adopted in the West, initially by the young, who wanted to demonstrate their solidarity with cultures uncontaminated by mass industry. The most ardent proponents of such folk costumes were the hippies. Hippies dress was sometimes decribed as 'anti-fashion', produced by a patchwork of ragged cast-offs and flamboyant accessories, of outmoded Western dress and time-honored ethnic garments all combined, modified and permutated into variety of personal statements. 'Flower Power'became a reality. From the results of this study, we can see the expanding trend of the influence and the concept of the sew art genre 'Happening'in the formativeness as well as the fine arts field.

Up to 35% of the rice genome consists of various kinds of transposons, and CACTA and MITE are two of the major class 2 DNA transposons in the genome. We have employed the consensus sequences of Rim2/Hipa CACTA, Stowaway MITE Pangrangja, and Tourist MITE Ditto for transposon display (TD) analysis to locate them on a genetic map, with 58 SSR markers used to anchor them. The TD analysis produced a high profile of the polymorphisms between the parental lines, Oryza sativa var. Gihobyeo/O. sativa var. Milyang, in intraspecific $F_{15}$ RIL lines, locating 368 markers of Rim2/Hipa CACTA, 78 markers of Tourist MITE Ditto, and 22 markers of Stowaway MITE Pangrangja. In the segregation analysis, non-parental segregating bands and segregation distortion bands were observed. The recombinant genetic map spans 3023.9 cM, with 5.7 cM the average distance between markers. The TD markers were distributed unequally on the chromosomes because many TD markers were located in pericentric chromosomal regions except in the cases of chromosomes 2, 3, 6 and 9. Although the number of transposon markers was not sufficient to include all rice class 2 transposons, the current map of CACTA and MITE transposons should provide new insight into the genome organization of rice since no previous DNA transposon map is available.

Purpose: In this paper, we show our blending ratio of 10 types of Essential Oils that survives beneficial bacteria and kills harmful bacteria in the scalp, and we investigate the possibility of application of our blending ratio to the development of anti-dandruff products and the possibility of being used as a raw material for clinical beauty and customized cosmetics. Methods: The scalp microorganisms used in our study were M. furfur, S. epidermidis, E. coli, and P. nitroreducens. There are a total of 10 Essential Oils such as True Lavender, Lime, Roman chamomile, Rosemary camphor, Cedarwood, Geranium, Clove, Tea tree, Palmalosa, and Peppermint. The antibacterial test of the blended Essential Oil was carried out according to the test method of the standardized evaluation methodology of "Food and Food Additives Code". Since M. furfur is related to the growth of sebum in the scalp, in this study we used the fnLNB and the fnLNA with 20 ㎖ of whole fat cow milk added. Results: The blending ratio of EO, which inhibits dandruff-causing bacteria such as M. furfur, S. epidermidis, E. coli, and does not inhibit P. nitroreducens showing dominant growth in a healthy scalp, was B8(Clove 0.2%, Roman chamomile 0.5%, Tea tree 0.3%), B9(Geranium 0.1%, Palmarosa 0.1%, Roman chamomile 0.5%, Tea tree 0.3%), B10(Clove 0.1%, Geranium 0.1%, Palmarosa 0.1%, Roman chamomile 0.5%, Tea tree 0.2%). Conclusion: It is thought that the blending ratio of BEO obtained as a result of this study can provide a basis for use as an alternative to antibiotics in developing anti-dandruff drugs and emerge as a new alternative to solve scalp microbial imbalance. In order for EO to be used as a useful raw material for anti-dandruff preparation, researches on 1) Standardization (the effects of products differ according to the types, regions, climate, extraction methods, etc.), 2) Antimicrobial effects, 3) Safety, etc., must be established.

In correlation to the rapid growth of Korea's economy and increased international exchange, hotel architecture in Korea has likewise evolutionized in its own distinctive style. Since hotels accomodate foreign visitors, they should be representative of the local architecture in which they reside, to add to the experience of the regions culture. City hotels provide not only primary housing functions but also many different varieties of services. Furthermore, city hotels operate as a focal point for their local communities. Seoul announced special measures for the expansion of accommodations for foreign tourists, and a large number of hotel construction entities have consequently propagated. Unfortunately, the designs for most of these new hotels have failed to reflect their local cultural characteristics, with most having similar designs and programs. As Korea enters an era seeing ten million foreign tourists annually, progressive reform is especially necessary. Space marketing, which is based on strategies of cultural experience, is a crucial element to city boutique hotel planning. It must be applied to satisfy both the cultural needs of its local communities and well as to vitalize the local economy through development of cultural tourism. To date, there have been numerous studies on boutique hotels and space marketing. However, most of these studies are limited to interior designs and artistic trends rather than focusing on the unique architectural and public aspects of their respective cities. In this thesis, the overall aim and strategies of space marketing for the city boutique hotel are analyzed, and the elements of strategies are used for further case analysis. The purpose of this study is to find applicability of Korean boutique hotel development through the result of case studies. Also, this thesis aims to advocate space marketing for Korea's forthcoming boutique hotels, as a means to showcase its unique cultural assets as well as to advance its international appeal and competitiveness.

Interdigital tissue regression is one of the most well-known examples of embryonic programmed cell death, providing the mechanism behind separation of developing digits. Caspases have been shown to play a key part in this process, with activated caspase-3 localized between the developing digits. In caspase-3 knock-out adult mice, however, the digits are completely separated with no webbing. In other mutants with defects in the apoptotic machinery, such as Apaf1 deficient mice, interdigital tissue regression is initially inhibited but the webbing eventually disappears as alternative/additional cell death mechanisms step in. In order to investigate whether a similar temporal effect occurs after loss of caspase-3, we have used an in vitro approach to inhibit caspase-3 at specific times during digit separation. Previous limb explant culture approaches have encountered problems with proper limb development in culture, and thus a modified technique was used. The new approach enables detailed observation of the effects of caspase-3 inhibition on interdigital regression. Using these methods, we show that caspase-3 inhibition caused a delay in the loss of interdigital tissue compared with control explants, similar to that observed in Apaf1 mutant mice. Along with immunohistochemistry, active caspase-3 positive cells of the interdigital vs. digital regions were measured by flow cytometry. Notably, activated caspase-3 in vivo was found not only in the interdigital mesenchyme but also in the TUNEL negative digit region, supporting a role for caspase-3 in nonapoptotic events.
