  • To promote the growth and proliferation of in vitro rose (Rosa hybrida L) shoots, a liquid medium was added to shoot culture. Shoots were obtained by culturing internodes of four cultivars, 'Antique Curl', 'Shiny Orange', 'White Zen', and 'Red Zen', and then were proliferated by the subculture two times. An addition with 10~15 mL of liquid medium enhanced the shoot elongation of all four cultivars. However, the effect of liquid medium addition to culture of in vitro shoot for proliferation was dependent on cultivars of rose.

  • This study aims to analyze the characteristics of deconstruction-ism expressed in the fashion of Alexander McQueen. The method and contents of this study are as follows. The three large categories for analysis are indeterminacy, decentralization, and intertextuality. The indeterminacy of meaning is divided into unstructured and unorganized factors in fashion, while decentralization can be categorized into cross-gender, subculture, and post-humanism. Lastly, inter-textuality is classified into factors of mixing mode and mixed styles. Materials for analysis were chosen from a total of 616 designs from the website, www.firstview.com, which carries McQueen's collection from 2000 S/S through 2007 F/W. My analysis qualitatively evaluates the frequency of each category and the characteristics of design. The result of this study is as followed. First, the avant-garde facets of inter-textuality are most prominent. In particular, McQueen has introduced retro fashion and ethnic factors of the third world, not to copy them but to create hybrid designs by using pastiches and mixing fashion styles. Moreover, he has enjoyed using two fabrics of different texture in order to inflict a shock and contrast, thus enriching his fashion. Second, the indeterminacy of meaning is the second most frequently shown facet of McQueen's fashion design. McQueen has employed unstructured expression techniques, which dismantle harmony and balance, the basic rule of design, and has presented unorganized images free from basic forms of design. He has made a new attempt to acknowledge clothing as an expressive artwork by allowing clothes to take a complete form when a person actually wears them. Third, the aspects of decentralization were also shown in McQueen's design. His trans-gender clothing dissolves the traditional division of men and women and adopts a mixed gender expression. Furthermore, he has even tried to express a fourth gender by connecting the human with machine or animal or by connecting the material with the non-material.

  • Having studied the production of monoclonal antibodies for developing a diagnosis medicine which shall be detected by a high-sensitivity test by using Rhodotorula rubra as a fungi-host which had been extracted through biochemical tests and follow-up examinations on Yeast-like fungi obtained from pulmonary tissues of pulmonary tuberculosis patients who had been in Kong ju National Tuberculosis Hospital from Jun. to Dec. in 1987, I. have gained such results as follows: 1. The fusion rate was influenced by feeder cell layers, cell density and time required to the cell fusion with cells in myelona subculture. 2. The fusion rate did not show any significant difference when the cell was applyed with two molecular weights, i.e., 1500 and 4000, of polyethylene glycol. 3. Fused cells after the addition of HAT selection media were bright and round, whereas unfused myelona cells and spleen cells were shrunk and granulated. 4. The cell fusion rate turned out to be about $57.2\%$(150 wells / 264 wells). 5. $10\%$(15 wells / 150 wells) of the positive reaction was detected in monoclonal antibody screening. 6. The titer which had reacted positively to Rhodotorula rubra fungal-host was 800 times in density after the gradual dilution of the produced monoclonal antibodies with Indirect ELISA method. 7. The Strongest specific reaction came out after the peroxidase labelled anti-human Immunogobulin had been applyed to Rhodotorula rubra for activating its nature after making drift with Carbonate-bicarbonate buffer (pH 9.6) and drying completely.

  • Articular cartilage is an important factor for studying the arthritic diseases. The chondrocyte isolated from cartilage has the characieristic of differentiation and rf-differentiation when cultured in monolayer The bee venom (BV) acupuncture was investigated to examine their abilities on chondrocyte re-differentiation via rabbit chondrocyte primary culture. And the expression profiles of type II collagen (COL2) was analyzed using RT-PCR and western hybridization at third passage chondrocyte. In general, the mRNA expression of type II collagen was reduced step by step with the subculture of the chondrocyte. However, after the BV treatment for 48hr at third passage, the expressions of type II collagen were found to be significantly up-regulated, the same result was confirmed by western blotting. These results suggested that the diluted solution of BV for herb-acupuncture was very effective on the recovery of articular chondrocyte phenotype.

  • The twin-scale segments of nerine (Nerine bowdenii) were cultured to investigate the influence of NAA, BA and sucrose concentrations on in vitro bulblet formation. The formation of bulblets from twin-scale segments showed a good response both the percentage of bulblet formation and the number of bulblets per explant on MS medium supplemented with 1mg/L NAA and 2 mg/L BA. Formation of bulblet showed the highest efficiency on medium containing 30g/L, and the formation of bulblets was strongly inhibited on medium containing over 90g/L. When the twin-scale segments formed bulblets were subcultured three times to the same medium by 60 day subculture interval, the number of bulblets per explant was 6.5, 7.3 and 8.2 in order of first, second and third. The bulblets over 3mm in diameter were hypertrophied and rooted after transferring to the hormone-free MS medium. The plantlets over 50mm in height were successfully acclimatized in the soil mixed with the same volume of vermiculite and perlite, and the survival rate was over 95%.

  • Experiments were conducted to find out the optimum cultural conditions for adventitious shoot regeneration from leaf segments of Gypsophila paniculata L. Thidiazuron (TDZ) was remarkably effective for the regeneration of leaf segment in Gypsophila paniculata compared with BA and kinetin. TDZ showed the highest rate of regeneration at $3.0mg{\cdot}L^{-1}$, while kinetin did not affect the regeneration. BA in the medium increased vitrification. Shoot formation efficiency was much higher on $0.3mg{\cdot}L^{-1}$ of IAA-containing media than NAA-containing media. Regeneration of leaf segments was induced with the agar concentrations of 1.0, 1.2 and 1.6%. Dark treatment at the initial stage of the culture increased the rate of regeneration up to 75%. The leaf explants from the 3rd subcultured stock plants after meristem culture, showed the highest adventitious shoot regeneration efficiency.

  • Into the 1990s, there have been changes in perception of pop culture consumers by making a distinction between groups that are active, critical and creative. This study aims to establish a theoretical reasoning for conventions organized and participated voluntarily by fans, which has been especially noticeable in the American subculture for a long time, while investigating how fans and all the parties concerned interact at conventions then to expand the imaginary world. To this end, an analysis has been carried out on the conventions for the particular American TV series of Supernatural. The results show that the reason for this drama series maintaining such enduring vitality as if a living thing is attributable to the special bond of sympathy developed between fans and actors and the following interactions between them. Furthermore, in the aspect of cultural sociology, a piece of work can only be completed through unconstrained interpretation of the work and the resultant recreation by the creator and the receiver, which has been ascertained by this study.

  • The purpose of this paper is to introspect again the role of the criminal law at a time when it is said that numerous criminal and legal discussions are needed to develop the so called "reply manipulation " case that is shaking the nation's political history. The research method considered the literature and precedents discussed in the past, and discussed the issue of subculture abuse caused by the internet, which is a product of convenience and affluence that came with the Forth industrial revolution through criminal law. Through a computer program, a discussion was held on what penalties would be imposed on the criminal law for attempting to manipulate public opinion by manipulating the so-called number of comments or Reaction. Question of whether the criminal law should further emphasize the need for a discussion on the need for a method to strengthen the preventive functions of the criminal law and expand the scope of punishment in order to address new causes of risk that came with the development of science. Without reflecting on whether such as "government-inspired demonstration "would be possible in today's world that was in the public perception of the authoritarian government of the past, it is a problem to see that the political goals of a particular group can be achieved by manipulating comments or creating public opinion on the Internet. The duty of criminal law is to protect the interests of the law. The role of the criminal law should be maintained the self limiting as far as possible in cases of violation or danger of the law. Still, it is a problem that the role of the criminal justice system today is too aggressive and is seen as a top tool rather than a last resort for solving problems. he role of the internet will be expanded further in the Hyper Connected society. To solve these problems, we should look forward to a change in the priority of other laws and policies other than criminal law.

  • As the global trend of Retro combined with the tendency of individualism which respects dramatic change and diversity in the 21st century, Goth subculture of Korea developed into various popular styles. This study, noticing the influences of Goth to the Korean youth culture and fashion trends, intends to examine the current fashion trends to analyze the various aspects of the influences of Goth to the Korean youth culture. To do this, various documents and numerous Internet materials on the Korean Goth culture are comprehensively reviewed, and the Goth look images of popular stars, photographs from fashion magazines and fashion collections are gathered, analysed, and classified into types, and the specific characteristics of these types are comprehensively analysed. According to the result of this research, Punk Goth look, departing from the sensational and aggressive style of Punk look, expresses sexy and luxurious images, while Romantic Goth look shows the brilliant and cheerful style by mixing the cute girlish image and the elegant feminine image of exaggerated details and voluminous silhouette. Avant garde Goth look parodies Goth image by using the dramatic effects of Goth images or is expressed in performances. Sexy Goth look, which reveals the sexual attractiveness of men and women much more assertively, tries to do suggestive representation and excessive exposure of human body. Dandy Goth look, which has the simple and modern line, expresses the calm and chic feeling by employing basic items with minimized details and coordinating unique accessories for accent.

  • C-1 compounds are observed in anaerobic sediment of high salt environments. Thus, surface sediments and waters from these environments are therefore potential habitats for aerobic methylotrophic microorganisms. The soil samples collected from saltern and tidal flat as inoculums and methanol as carbon and energy source was supplied. After subculture depending on the salt concentration, methanol oxidizing bacteria growth condition investigated, the results of methanol oxidizing bacteria can grow in salt conditions, and the maximum concentration was 20%. Analysis based on denaturing gradient gel electrophoresis of 16S rRNA genes indicates that Methelyophaga-like bacteria were dominants of methylotrophs in the enrichment culture. Quantitative PCR showed that archaeal cells were about 1-10% of bacterial cells. Additionally archaea were assumed not to be involved in methanol oxidation since bacterial antibiotics completely blocked the methanol oxidation. Our results suggest that Methelyophaga-like bacteria could be involved in C-1 compounds oxidation in hypersaline environments although those activities are sensitive to salinity above 20%.
