  • The carp $\beta$-actin regulatory sequences and RSV/LTR promoter were tested whether they are functinal to express linked structure gene (chloramphenicol acetyltransferas, CAT) in olive flounder (Paralichthys olivaceus) by determining the patterns of gene expression following intramuscular in vivo direct injection. The injection experiments with various concentrations of both pRSVCAT and pFV4CAT clearly revealed the effectiveness of DNA dosage on expression of CAT. The increase of CAT activity was linear in both plasmids, and maximal CAT activity was obtained with 100 ug of pFV4CAT injection. The amounts of CAT expression with pFV4CAT-injected fist were higher than those with pRSVCAT-injected fish. CAT activity was readily detectable as early as one day after injection, slightly increased at day 2, and declined over time. Most amount of DNA intramuscularly injected into olive flounder muscles persisted extrachromosomally without showing any integrated or replicated form in vivo.

  • Embryonic genome activation (EGA) is the first major transition that occurs after fertilization, and entails a dramatic reprogramming of gene expression that is essential for continued development. Although it has been suggested that EGA in porcine embryos starts at the four-cell stage, recent evidence indicates that EGA may commence even earlier; however, the molecular details of EGA remain incompletely understood. The RNA polymerase II of eukaryotes transcribes mRNAs and most small nuclear RNAs. The largest subunit of RNA polymerase II can become phosphorylated in the C-terminal domain. The unphosphorylated form of the RNA polymerase II largest subunit C-terminal domain (IIa) plays a role in initiation of transcription, and the phosphorylated form (IIo) is required for transcriptional elongation and mRNA splicing. In the present study, we explored the nuclear translocation, nuclear localization, and phosphorylation dynamics of the RNA polymerase II C-terminal domain in immature pig oocytes, mature oocytes, two-, four-, and eight-cell embryos, and the morula and blastocyst. To this end, we used antibodies specific for the IIa and IIo forms of RNA polymerase II to stain the proteins. Unphosphorylated RNA polymerase II stained strongly in the nuclei of germinal vesicle oocytes, whereas the phosphorylated form of the enzyme was confined to the chromatin of prophase I oocytes. After fertilization, both unphosphorylated and phosphorylated RNA polymerase II began to accumulate in the nuclei of early stage one-cell embryos, and this pattern was maintained through to the blastocyst stage. The results suggest that both porcine oocytes and early embryos are transcriptionally competent, and that transcription of embryonic genes during the first three cell cycles parallels expression of phosphorylated RNA polymerase II.

  • This study focuses on comparative study of the representation of 'traditionality' in Asian hotel guest rooms. Hotel can be a concentration of the country's culture and tradition and provide unique experience to guests through its space, decoration, and material. However, most hotels in Korea are lack of a strong identity based on the Korean culture and tradition, due to adoptation of the western hotel styles without any criticism. The purpose of this study was to investigate the expression methods of the traditionality in Asian hotel guest rooms to provide design guideline to enhance identity of hotel guest rooms in Korea. Through analysis of the previous researches, criteria of the three design application methods and the five design elements were defined to analyze the representation of the traditonality. Design application methods were categorized as "Original form", "Partial adoption", and "Metaphor". Five design elements include "Shape", "Material", "Color", "Object", and "Pattern". Thirty nine Asian hotels containing the traditional design elements were explored in the study. In result, design application methods in Korea used all three methods equally, while other Asian countries used mainly the Partial adoption and Metaphor methods to express their traditions rather than the Original form method. All five deign elements were mostly used in case of the Original form methods, and two or three elements among five elements were used for the Partial adoption and Metaphor methods. The traditional representation of hotel guest rooms in Korea, reflecting current thinking, living pattern and culture, will be a solution for the new hotel design as well as elevation of Korea's status to a higher level.

  • The purpose of this study is to develop a creative perspective technique in fashion illustration through analyzing perspective in visual art experienced a great variety. This study was analyzed by examining the general theories based on the discovery of perspective and investigating the modern perspective in fashion illustration related to the method of spatial expression in visual art. A complex perspective of existing perspective gives the effect of reapperance of actual space and three-dimentional form in a plane. Because of being used as not only one perspective technique but also some perspectives technique, its expression can be more realistic. An amplified perspective gives the effect of visual illusion just like being suck in space inside and come out from screen outside by distorting the human body. A confused perspective of space gives the visual illusional effect of collapsing actual space and misunderstanding three-dimensional form by distorting the form of the space and changing the nature as an object of fashion. A reiterated or duplicated perspective gives effect of interpreting invisible space as imaginary space by overlapping and eliminating the object of fashion. An irrational perspective of spatial illusion gives the effect of disorganization experienced thinking by strange shapes and new recognition of irrational space by extraordinary visual connection. It has a tendency to surrealism. In conclusion, the modern perspective in fashion illustration has made the best use of not only new perspective since 1980, but general perspective before 1980. By the modern perspective expression. the viewer has made a chance to experience imaginary spaces indirectly, and the author has been able to express emotions by his or her new attempt in the screen.

  • Based on a concept of Nietzschean nihilism, this study aimed at interpreting the nihilism in arts and its expressions, also analyzing the modern fashion collection from the same angle. The research was centered on arts after 1980, when post-modern formal destruction expanded in earnest and on the fashion collection after the 20th century, easily accessible to data. Particularly, it set 1994 nihilism collection by Alexander McQueen, a representative nihilist fashion designer as a starting point. Nietzsche mentioned that true arts may be achieved when Apollonian characteristics including a bodily sensory system and an idealization process and Dionysian characteristics including every human feeling are integrated. Besides, he emphasized the importance of an artist being represented as an image of ${\ddot{U}}bermensch$. The ${\ddot{U}}bermensch$ image, reflected in arts and artistic nihilism, represents themes of violence/death, realistic/unrealistic expressions, human body/inhuman aversion materials and the transmutation of a form. Fashion collection expressions, owing to the special characteristic of the show form unlike other arts, were segmented as a realistic ${\ddot{U}}bermensch$ image using a model in a theme, expression, material and form. The theme of violence/death was divided into the death of human and a society. Human life/death was expressed as destruction of human weakness and self-identity, sexual objectification and violence, and social death as destruction and conflict of a class, nation, culture and nature. As for the expression, it was divided into the realistic expression of the primitive/natural and directing of an unrealistic atmosphere using a show.

  • The eventual goal of tumor immunotherapy is to develop a vaccine inducing a specific anti-tumor immunity. Cytokine gene therapy is an effective way at least in animal models, but limited efficacy and various side effects obstruct clinical applications. In this study, we developed a tumor vaccine expressing a membrane-bound form of IL-2(mbIL-2) and SDF-1 in B16F10 melanoma cells. The tumor clones expressing mbIL-2 showed reduced tumorigenicity, and additional expression of SDF-1 to mbIL-2 expressing tumor cells caused more severe reduction in tumorigenicity. However, expression of the SDF-1 alone did not affect on the tumorigenicity, probably because of limited production of SDF-1 in the SDF-1 transfected clones. When the mice once rejected mbIL-2/SDF-1 expressing tumor clone were re-challenged with wild type B16F10 tumor cells, all of the mice survived. This result suggests that mbIL-2/SDF-1 tumor clone is effective in inducing systemic anti-tumor immunity against wild type B16 melanoma. Furthermore, culture supernatant of tumor clones expressing SDF-1 induced lymphocyte migration in vitro. These results, all together, suggest that expression of mbIL-2 and SDF-1 in tumor cells enhances anti-tumor immune responses through different roles; the secreted SDF-1 may function as a chemoattractant to recruit immune cells to tumor vaccine injection site, and the mbIL-2 on tumor cells may provide costimulatory signal for CTL activation in physical contacts.

  • Aquifex pyrophilus, a hyperthermophilic bacterium, has a serine-type protease that is located at the cell wall fraction with a mature size of 43 kDa. Molecular cloning of the protease gene revealed that it has an ORF of 619 amino acids with homologous catalytic site of serine-type proteases [Choi, I.-G., Bang, W.-K., Kim, S.-H., Yu, G. Y., J. Biol. Chem. (1999), Vol. 274, pp. 881-888]. Constructs containing different regions of the protease gene, including a alanine-substituted mutant at the active site serine, were constructed, and the factors affecting the expression level of the cloned protease gene in E. coli were examined. The presence of the C-terminus hydrophobic region of the protease hindered over-expression in E. coli. Also, the proteolytic activity of the expressed protein appeared to toxic to E. coli. An inactive form that deleted both of the N-terminal signal sequence and the C-terminal polar residues was over-expressed in a soluble form, purified to homogeneity, and its thermostability examined. The purified protein showed three disulfide bonds and three free sulfhydryl group. The thermal denaturation temperature of the protein was measured around $90^{\circ}C$ using a differential scanning calorimeter and circular dichroism spectrometry. The disulfide bonds were hardly reduced in the presence of reducing agents, suggesting that these disulfide bonds were located inside of the protein surface.
