The purpose of this study is to rediscover the hidden value of non-mainstreamers style which has been overlooked for the past decade by investigate the aesthetics and formative features of the Grunge fashion. The Grunge fashion was derived from explosive popularity of the early 90's grunge music. Grunge was the alternative anti-thesis against mainstream pop music and anti-fashion against mainstream fashion. Dirty, rubbish grunge style of the poor street youth and grunge musicians have raised to the high fashion by designers. And These trial of designers made people to notice the value of the non-mainstreamers street style like grunge. Actually, the grunge brought the shock with many argument to the 90's fashion field. But now, It became the classic of the street fashion. And It has potent influence on the music, culture and high fashion. The Grunge is a kind of links between music and fashion, street fashion and high fashion, sub culture and mainstream culture, the past and now. Grunge isn't only a fashion of appearance. It is the attitude of wearing clothes and living a life. Variety grunge style in the international street fashion, high fashion, typical musicians's fashion of the 1990's and the 2000's was researched for this study. These materials were gathered from music magazines, fashion magazines, movies, musics and books. As a results of analysis, Grunge has the formative features like mix & match, layering, patchwork, primitive edge, rag, retro, recycle, kinderwhore, sneer scribbling, disheveled hair. Grunge also has the Aesthetic features like the beauty of $disorder{\cdot}\;disharmony{\cdot}\;incompleteness{\cdot}\;kitsch{\cdot}\;poverty{\cdot}\;alternative{\cdot}\;eclectic{\cdot}$symbiosis. For the last 10 years, These features changed our fashion be more pluralistic and dynamic.

유기게르마늄(Ge-132, carboxyethylgermanium)에 의한 22가지 젖산균의 성장 효과를 0.01~10mg/m1의 농도로 첨가된 GPYS 액체배지에서 조사하였다. 시험한 대부분의 젖산균은 고농도의 게르마늄에서도 내성이 있었고, 게르마늄의 농도가 높을수록 성장을 더욱 촉진시키는 효과가 나타났다. 게르마늄이 10mg/m1의 농도로 첨가된 GPYS배지에서 Lactococcus factis, Lc. cremoris, Lc. diacetilactis, Enterococus faecium 및 Streptococcus faecalis는 2배 이상 생육촉진의 효과를 나타내었으나, Leuconostoc mesenteroides와 Pediococcus pentosareus는 저해를 나타내었다. Lc. lactic와 Lc. cremoris의 경우, 배양액의 점도는 게르마늄이 첨가된 GPYS배지에서 급격히 증가되었지만, 장시간 배양에 의해서는 약간 감소되었다. 그러나 Lc. diacetilactis, E. faecium와 S. faecalis의 경우, 게르마늄의 첨가에 의하여 생육은 현저하게 촉진되었지만, 배양중의 점도는 증가되지 않았다.

There is growing interest in the production of microalgae-based, high-value by-products as an emerging green biotechnology. However, a cultivation platform for Oocystis sp. has yet to be established. We therefore examined the effects of bacterial culture additions on the growth and production of valuable compounds of the microalgal strain Oocystis sp. KNUA044, isolated from a locally adapted region in Korea. The strain grew only in the presence of a clear supernatant of Sphingomonas sp. KNU100 culture solution and generated 28.57 mg/l/d of biomass productivity. Protein content (43.9 wt%) was approximately two-fold higher than carbohydrate content (29.4 wt%) and lipid content (13.9 wt%). Oocystis sp. KNUA044 produced the monosaccharide fucose (33 ㎍/mg and 0.94 mg/l/d), reported here for the first time. Fatty acid profiling showed high accumulation (over 60%) of polyunsaturated fatty acids (PUFAs) compared to saturated (29.4%) and monounsaturated fatty acids (9.9%) under the same culture conditions. Of these PUFAs, the algal strain produced the highest concentration of linolenic acid (C18:3 ω3; 40.2%) in the omega-3 family and generated eicosapentaenoic acid (C20:5 ω3; 6.0%), also known as EPA. Based on these results, we suggest that the application of Sphingomonas sp. KNU100 for strain-dependent cultivation of Oocystis sp. KNUA044 holds future promise as a bioprocess capable of increasing algal biomass and high-value bioactive by-products, including fucose and PUFAs such as linolenic acid and EPA.

Vitellogenin (VTG) and VTG mRNA induction by $estradiol-17\beta\;(E_2)$ were examined in the primary cultures of hepatocyte in the rainbow trout. Hepatocytes were precultured for 2 days, then $E_2$ was added and cultured for another 5 days. Media and hepatocytes were then analyzed by electrophoresis and Northern blotting for VTG and VTG mRNA, respectively. The hepatocytes were formed a few aggregates within 5 days without further spreading to a monolayer. Cell viability and high DNA content were maintained during the incubation. The hepatocyte culture with E2 induced a weak VTG band at a molecular weight of 175kDa on Day 2 after $E_2$ addition. The relative amount of VTG was expressed in percentage of total protein concentrations. VTG was gradually increased as $1.9\%$ on Day 2, $6.3\%$ on Day 4 and $7.3\%$ on Day 5. VTG mRNA band was detected at about 6.6 kb in the culture with $E_2$ at day 1 of culture. The level of VTG mRNA expression linearly increased with time until Day 5 (r=0.97).

The physiological characteristics of cultures of very high cell mass (e.g. 10g cell mass/L), termed“ultrahigh cell density cultures”is reviewed. A close relationship was found between the length of the optical path (OP) in flat-plate reactors and the optimal cell density of the culture as well as its areal (g m$\^$-2/ day$\^$-1/) productivity. Cell-growth inhibition (GI) unfolds as culture density surpasses a certain threshold. If it is constantly relieved, a 1.0cm OP reactor could produce ca. 50% more than reactors with longer OP, e.g. 5 or 10cm. This unique effect, discovered by Hu et al. [3], is explained in terms of the relationships between the frequency of the light-dark cycle (L-D cycle), cells undergo in their travel between the light and dark volumes in the reactor, and the turnover time of the photosynthetic center (PC). In long OP reactors (5cm and above) the L-D cycle time may be orders of magnitude longer than the PC turnover time, resulting in a light regime in which the cells are exposed along the L-D cycle, to long, wasteful dark periods. In contrast, in reactors with an OP of ca. 1.0 cm, the L-D cycle frequency approaches the PC turnover time resulting in a significant reduction of the wasteful dark exposure time, thereby inducing a surge in photosynthetic efficiency. Presently, the major difficulty in mass cultivation of ultrahigh-density culture (UHDC) concerns cell growth inhibition in the culture, the exact nature of which is awaiting detailed investigation.

Fusarium proliferatum KGL0401 was previously isolated from Physalis alkekengi var. francheti plant roots and exhibited a high GA productivity. A gas chromatography-mass spectrometry (GC-MS) analysis of extracts of the culture fluid of F proliferatum KGL0401 also revealed the presence of $GA_1$, $GA_3$, $GA_4$, $GA_7$, $GA_{20}$, and $GA_{24}$. Therefore, the present study conducted a proteome analysis of waito-c rice treated with the culture fluid of the isolated F proliferatum KGL0401 to identify the protein expression triggered by the GA-containing culture fluid. The results revealed the overexpression of 180 protein spots in the sample treated with the culture fluid. Among them, 75 induced proteins were selected and analyzed by MALDI-TOF (matrix-assisted laser desorption-iorrization time-of-flight) mass spectrometry, followed by database searching, and 51 proteins were identified.

We're living in a world of one global village. The globalization of business is acceleration as more companies cross national borders to find customers, materials and money. Many foreign companies and organizations are doing their business aggressively in Korea and many Korean companies and rushing into foreign market. When people communicate for business with someone from another culture, there could be difficult communication barriers to overcome resulting from differences in their values, beliefs, norms for behavior, expectations, attitudes and so on. To do successfully business, we need to understand culture background and communication style that is different from nation, race, language. Communication barriers stemming from cultural differences may vary. Largely, they can be divided into value system, non-verbal communication, and perception process. Value system can be divided into individualism versus group orientation, avoidance of uncertainty degree, power distance, and high- context culture versus low-context culture. Also non-verbal communication method and perception process may play decisive roles in communication effectiveness. Especially nonverbal communication barriers which sometimes play more important roles than the verbal parts are composed of eye contact, gesture, kinesics, proxemics, chronemics, paralanguage and language of color Cross-cultural communication affect business situation. I expect that if we understand cultural background, and then we overcome cross-cultural communication barriers. To overcome and to adapt inter-cultural business, we need to develope curriculum on the cross-cultural education which I will study in the next paper.

The biological wastewater treatment system is known to have an important role in reducing the quantify of enteric virus in water environments. To clarify the roles of activated sludge microbes in decreasing the virus infectivity, the behavior of the virus in bacteria, protozoa, and metazoa was examined by pure or mixed culture system using poliovirus type 1(Lsc, 2ab strain). In the bacterial culture systems, the virus infectivity in the liquid phase decreased by a reversible adsorption of the virus to the bacteria or bacterial flocs. On the other hand, in the protozoa and the metazoa culture systems using T. pyriformis and P. erythrophthalma, respectively, with a variety of bacterial strains as prey, the main virus decrease mechanism of reversible adsorption in early stage was changed to irreversible predation, which was not eluted in this study. The virus decrease was more effective in the P. erythrophthalma culture system, which had high predation and floc forming abilities. However, in the mixed culture system of Z. ramigera and P. erythrophthalma, the more rapid reversible adsorption of virus to Z. ramigera flocs preceded the irreversible predation of P. erythrophthalma.

Background: Induced sputum (IS) has been used to collect airway secretions in subjects who have inadequate sputum production. The aim of this study was to investigate the efficacy of IS for the diagnosis of pulmonary tuberculosis (PTB) in adults unable to expectorate sputum. Methods: Medical records of 39 PTB patients who underwent IS due to absence of spontaneous sputum production between January 2011 and March 2014 at a tertiary hospital in South Korea were reviewed. Results of acid fast bacilli smear, Mycobacterium tuberculosis culture and polymerase chain reaction assay for M. tuberculosis (TB-PCR) of IS specimens from these patients were analyzed. Clinical and high-resolution computed tomography (HRCT) characteristics were also analyzed to find characteristics associated with IS culture positivity. Results: Of the 39 IS specimens from PTB patients, 7 (17.9%) were smear positive and 31 (79.5%) were culture positive. Twenty-four IS specimens were tested for TB-PCR and 13 (54.2%) were positive on TB-PCR. Multivariate analysis showed that younger age (p=0.04) and presence of tree-in-bud appearance on HRCT (p=0.03) were independent predictors of IS culture positivity. Conclusion: IS is useful for the diagnosis of PTB in adults unable to expectorate sputum. Younger age and tree-in-bud appearance on HRCT were associated with IS culture positivity in these patients.

The purpose of this study was to examine formative aesthetic characteristics and aesthetical value of the intraculturalism expressed in contemporary fashion and to confirm the functions of intraculturalism to establish, visualize, perform the racially indeterminate, ethnically neutral, culturally diverse or ambiguous identity. For this study, the applications of the intraculturalism shown in mass media and consumer culture, such as music, fashion advertisements and collections of high fashion designers from 2004 to 2008 have been analyzed and compared. The results were as follows: The Intraculturalism is reflected in the muticultural music such as Afropean, Jawaiian, Reggaeton and Asian Hip Hop. Intracultural music genres create the hybrid music and fashion culture through mixing, matching and blending one and another culture. Advertisement campaigns for Louis Vuitton, YSL Beauty, Gap and H&M stores have all purposely highlighted models with mixed racial heritage. It is reflected in the latest youth fashion market trend using face that are ethnically ambiguous. The increasingly multiracial, multicultural population is due to intermarriage and waves of immigration. The rising mixed race designers, Narciso Rodriguez, Hussein Chalayan, Vera Wang and DooRi Chung, not only compromise and amalgamate different cultural elements of their heritage and contemporary life but also create new look and fashion image. The characteristics of intraculturalism expressed in the 21st century fashion could categorized into de-genre, de-nationality, de-race and de-culture.
