This study is on the works of Hussein Chalayan that is an expression of his idea and abstract concepts such as culture, history, time, space, nature, and humanity. The perspective of E. H. Gombrich is studied to understand the works of Chalayan who is the one of representative fashion designers in the present age. The 'schema and correction' process of E. H. Gombrich provides a suitable interpretation frame that considers the variety of works of art and the deconstruction of genre in the after 20th century. Hussein Chalayan attempts to combine clothes with other territories to show the spirit as materiality. He expresses the clothes that speaks the form of nature, symbolizes the combination of culture, visualizes time and space, and investigates the existence of human beings. Hussein Chalayan poses an endless question about the existence of human beings. He has put a question about the relationship of the human being and time, space, history, and nature. His trial to visualize the metaphysical conception of 'ego' and 'self' through his works makes him the representative designer of the 21st century.

Using a data set drawn from 1419 college students, this study analyzes what implications clothing or fashion has on self-expression or image management in Korean society and who are more likely to use fashion as a image management tool in the process of interacting with others. Employing Pierre Bourdieu's concept of capital, we discuss three theories concerning correspondence between class and fashion: the theory focusing on economic capital in emphasizing the correspondence; the theory focusing on cultural capital in emphasizing the correspondence and the theory emphasizing relationships between fashion and other factors rather than class. Based on the theoretical examination, we select independent variables that can be grouped into status/class variables, or economic capital variables(such as subjective status, income, father's education, father's occupation) and socio-cultural variables, or cultural capital variables(such as possession of cultural capital, desire for upward mobility). Upon regressing strategic use of fashion on independent variables, we find that both status/class variables and socio-cultural variables are statistically significant in explaining the strategic mobilization of fashion for one's image production or social success. It shows that class as a form of economic capital has important effects on the strategic use of fashion, and cultural capital also has effects independent of economic capital.

With the increased popularity of IEEE 802.11 WLAN, the density of the WLAN devices per access point has also increased, resulting in throughput performance degradation. One of the solutions to the problem is improving the protocol efficiency by a using multi-round contention scheme. This paper first discusses how to estimate the number of contending stations in a WLAN network by using minimum elapsed backoff counter values that can be easily monitored by each station. An approximate closed form expression is derived for the number of active contending stations using the smallest backoff counter value in the network. We then apply this result to adapt the number of contending rounds according to the network loading level to enhance the throughput performance of a multi-round contention scheme. Through simulation, we show that the accuracy of the estimation algorithm depends on the contention parameters of W and the number of backoff counter observing samples, and found a reasonable value for each parameter. We clearly show that our adaptive multi-round contention scheme outperforms the standard contention scheme that uses a fixed number of rounds.

The purpose of this study is to examine a user-centered and interactivity-based user-participatory design that could be completed by users by helping them to better understand a diverse experience and be involved in a design process. The aspects of expression that were marked by direct user participation and subsequent interactivity in the areas of design, the arts and fashion were investigated to determine their characteristics. The kind of fashion that is characterized by interactivity is of significance in that it is variable according to the purpose of the users, it's possible to have sustained communication with them through their direct participation, and that the designer is consequently able to build a new, communicative relationship with the users as co-creators. This study found that the characteristics of interactivity through direct user participation are classified into four characteristics; One is playfulness. which offers a new experience and way to create fun and vale. Another is variability, which is changeability of form; the third is the convergence of technology and function. Lastly, the fourth is virtuality. This is to embody images in virtual space.

This study action drama TV drama 'Ya-ha'(夜叉) the actual work practices of the pre-consultation stage through the Writers, Producer, Art directors and in consultation with the opinion of the character set the record of the contents and character changes over time in accordance with characters makeup the design elements were analyzed. The methods of study was used local and abroad related books, studies, publications and cases and the subjects were limited to be four male make up characters in drama 'Ya-cha'. As a result, TV action drama 'Ya-cha' make up design elements and representation techniques were classified as description of skin tone, wound, the shape of eyebrows, hair type, shape of beard and materials and carried out an important role in the character representation. First, presentation techniques changed skin tones depending on character and position and described wound shape as expression technique and materials were analyzed. Second, the shape of eyebrows was based on the physiognomy of the form. And hair type changed volume, thickness, length and texture depending on character. Third, shape of beard is expressed different kinds of volume, thickness, length and texture depending on character. There fore, that systematization of the make-up design elements is useful to express stable characters and make drama for make up in various image genres.

A short peptide corresponding to the nuclear localization signal (NLS) of human immunodeficiency virus (HIV)-l Tat protein, Arg-Lys-Lys-Arg-Arg-Gln-Arg-Arg-Arg, was employed to improve the efficiency of cellular uptake of nucleic acids. The peptide was first mixed with a reporter plasmid and then with cationic liposomes to form a tripartite complex of DNA/peptide/liposomes (DPL). Transfection efficiency of the DPL complex was compared with that of the conventional DNA/liposomes (DL) complex. When the DPL complex was formed with various cationic liposomes, DOTAP/DOPE (DP) liposome exhibited superior transfection efficiency to other liposomes tested in vitro. With the inclusion of the peptide, the DPL complex showed much enhanced transfection in various cancer cell lines. Particularly, transfection of the DPL complex in serum increased cellular uptake of a transgene up to 2 fold when compared with that in a serum free condition. Further, when the DPL complex was infused through the ureteric route of a rat, transfection efficiency was shown to be better in reporter gene expression than that obtained with the DL complex. This study shows that the DPL complex that is easy to formulate can be employed for much enhanced cellular uptake of a trans gene.

Flavonoids, which form a major component in Houttuynia cordata Thunb., display a wide range of pharmacological activities. The expression of plant flavonoids is partly regulated by fermentation. Therefore, we studied the effects of fermentation on H. cordata in order to identify the strains present during the fermentation process, and to determine whether fermented H. cordata could be used as a probiotic. Our results showed that all 6 of the bacterial strains isolated from fermented H. cordata (FHC) belonged to the genus Bacillus. As expected, fermenting H cordata also increased the flavonoid content as increases were observed in the levels of rutin, quercitrin, and quercetin. To test the effects of fermentation, we treated LPS-stimulated RAW264.7 cells with non-fermented H. cordata extracts (HCE) or FHC extracts (FHCE). Compared to the HCE-treated cells, the FHCE-treated cells showed increased viability. No cytotoxic effects were detected in the FHCE-treated groups in the 2 cell lines used in the study, namely, RAW264.7 and RBL-2H3. FHCE-treated HepG2 cells showed decreased growth, compared to HCE-treated HepG2 cells. These results indicate that the fermented H. cordata predominantly contained Bacillus strains. Furthermore, FHCE are able to prevent LPS-induced inflammatory effects and inhibit the growth of HepG2 cells.

The estrogen receptor (ER) is activated and degraded by estrogen. We have examined ER downregulation and activation under hypoxia mimetic conditions. Cobalt chloride induced ER downregulation at 24 h of treatment. This degradation involved hypoxia-inducible factor-1$\alpha$ (HIF-1$\alpha$) as examined by using a constitutively active form of HIF-1$\alpha$, HIF-1$\alpha$/VP16, constructed by replacing the transactivation domain of HIF-1$\alpha$ with that of VP16. Western blot analysis revealed that E2-induced ER downregulation was observed within ${\~}6h$, whereas HIF-1$\alpha$/VP16-induced ER degradation was observed within 12${\~}$20h. HIF-1$\alpha$/VP16 activated the transcription of estrogen-responsive reporter gene in the absence of estrogen. These results suggest that ER downregulation and activation under hypoxia maybe mediated in part by a HIP-1$\alpha$ expression.
