The purpose of this study is to evaluate the features of the finishing material according to their type and color. The purpose of this in order is to improve the pleasantness of the interior, by using the proper finishing materials, in planning the interior, and to apply it to framing the prediction model for practical use in interior design, This stud was conducted by evaluating experiment manufactured with the CG(Computer Graphics). The process of the study is as follows, 1) The finishing materials used in the interior based on the previous study was classified. The color range of the selected finishing materials was examined. 2) The evaluation experiment using the CG was conducted on the basis of the selected finishing materials. 3) With that result, the evaluation properties was analyzed according to evaluating variables(that is, the finishing material, hue, value, and chroma) for the interior image. 4) Finally, the prediction model of the interior finishing materials was framed with the image type. Through the Factor Analysis of 19 Adjectives, 8 representative image types such as 「Open·Bright」, 「Gorgeous·Strong」, 「Quiet·Natural」, 「Smooth·Elaborate」, 「Coarse·Rough」, 「Elegant·Refined, 「Warm」」 and 「Cool」 were extracted. The prediction model was framed for the 8 representative image types. The 「Open·Bright」, 「Quiet·Natural」, 「Cool」images are as follows, 1) When you want to produce the 「Open·Bright」image, it is ideal to use wallpaper as finishing material and Y or B in hues. The higher the value and middle chroma you use. The bigger 「Open·Bright」 the efficiency you achieve. 2) When you want to produce the 「Quiet·Natural」 image, it is good to use woods for finishing materials, You can get a better image with the YR or R in hues, with higher value and lower chroma. 3) When you want to produce the 「Cool」image, it is better to use stones for finishing materials. Cool colors and the hue of B, PB, BG are recommended. The lower value and chroma are effective as well.

Function of the pentose phosphate pathway and its key enzyme, transketolase, in the regulation of the meiotic cell cycle in oocytes

Kim, Yunna,Kim, Eun-Young,Seo, You-Mi,Yoon, Tae Ki,Lee, Woo-Sik,Lee, Kyung-Ah The Korean Society for Reproductive Medicine 2012 Clinical and Experimental Reproductive Medicine Vol.39 No.2

Objective: Previously, we identified that transketolase (Tkt), an important enzyme in the pentose phosphate pathway, is highly expressed at 2 hours of spontaneous maturation in oocytes. Therefore, this study was performed to determine the function of Tkt in meiotic cell cycle regulation, especially at the point of germinal vesicle breakdown (GVBD). Methods: We evaluated the loss-of-function of Tkt by microinjecting Tkt double-stranded RNAs (dsRNAs) into germinal vesicle-stage oocytes, and the oocytes were cultured in vitro to evaluate phenotypic changes during oocyte maturation. In addition to maturation rates, meiotic spindle and chromosome rearrangements, and changes in expression of other enzymes in the pentose phosphate pathway were determined after Tkt RNA interference (RNAi). Results: Despite the complete and specific knockdown of Tkt expression, GVBD occurred and meiosis was arrested at the metaphase I (MI) stage. The arrested oocytes exhibited spindle loss, chromosomal aggregation, and declined maturation promoting factor and mitogen-activated protein kinase activities. The modified expression of two enzymes in the pentose phosphate pathway, Prps1 and Rbks, after Tkt RNAi and decreased maturation rates were amended when ribose-5-phosphate was supplemented in the culture medium, suggesting that the Tkt and pentose phosphate pathway are important for the maturation process. Conclusion: We concluded that Tkt and its associated pentose phosphate pathway play an important role in the MI-MII transition of the oocytes' meiotic cell cycle, but not in the process of GVBD.

Background : Nosocomial candidemia is one of the most important disease entity in hospital not only because of increasing incidence but also because of its high fatality rate. The purpose of this study is to identify risk factors predicting the development of nosocomial candidemia and to evaluate its clinical outcome of nosocomial candidemia in the intensive care unit (ICU) patients. Materials & Methods : We conducted a retrospective, matched case-control study in adult patients admitted to ICU from January 1998 through December 2002 in Ewha Womans University Mokdong hospital. Sixty cases with candidemia were retrospectively identified from the records of the Department of Clinical Microbiology. The possible risk factors for the development of nosocomial candidemia were compared between 60 patients and 120 control subjects. Results : Candida albicans was the most commonly isolated organism. In the multivariate analysis, number of concomitant bacteremia (OR=17.3), number of candida infection in other site (OR=20.6), number of antibiotics used (OR=4.2), duration of indwelling central venous catheter (OR=16.1), and insertion of arterial line for more than 8 days (OR=6.9) were identified as significant risk factors for development of candidemia. Crude mortality rate was higher in candidemia patients compared with control subjects (P=0.004). Conclusion : The best predictors of development of candidemia in ICU patients were concomitant bacteremia, candida colonization in other site, combined use of antibiotics, and long-indwelling arterial and central venous catheter. For the ICU patients with high risk factors of candidemia, we could consider the intervention to prevent emergence of candidemia. 목적 : 원내 감염 칸디다혈증은 최근 의학 기술의 발전과 함께 면역 기능이 감소된 경우 특히 발생 빈도가 증가할 뿐 아니라 높은 치사율로 그 중요성이 강조되고 있다. 이 연구의 목적은 중환자실에 입원한 환자에서 칸디다혈증 발생의 위험 요인과 이로 인한 사망률을 파악하는데에 있다. 재료 및 방법 : 1998년 1월부터 2002년 12월까지 5년간 이화여대 목동병원 중환자실에 입원하였던 환자를 대상으로 후향적으로 입원 기록을 검토하여 환자-대조군 연구를 시행하였다. 환자군은 진단 검사의학과 미생물실 자료에 의거, 칸디다혈증이 있었던 60명을 대상으로 하였고 대조군은 같은 시기에 중환자실에 입원하였으나 칸디다 혈증은 없었던 120명으로 짝지어 각기 28개의 가능성있는 위험 인자와 치사율에 대해 조사하였다. 결과 : 칸디다혈증을 유발하는 균종은 Candida albicans가 24예(40%)로 가장 흔하였다. 다변량 분석을 통해서 균혈증이 동반된 경우(OR=17.3), 칸디다가 다른 부위에서도 검출된 경우(OR=20.6), 항생제 병용이 많을수록(OR=4.2), 중심정맥관 삽입 기간이 길수록(OR=16.1), 동맥관 삽입이 8일 이상인 경우(OR=6.9)가 중환자실 환자에서 칸디다혈증 발생의 독립적인 위험인자이었다. 보통 사망률(Crude mortality)은 환자군에서 48.3%, 대조군에서 26.7%로 칸디다혈증 환자에서 사망률이 유의하게 높았다(P=0.004). 결론 : 칸디다혈증의 발생은 균혈증이 동반된 경우, 다른 부위에서 칸디다가 검출된 경우에 증가하며, 항생제 병용이 많을수록, 혈관 내에 중심정맥관이나 동맥관이 장기간 유치되어 있을수록 증가하였다. 칸디다혈증의 사망률 역시 높아, 칸디다혈증의 위험이 높은 중환자실 환자를 조기에 색출하고 칸디다혈증 발생을 예방할 수 있는 방법들에 대한 연구가 필요하겠다.

Streptococcus mutans is known as the causative bacterial playing the most important role in forming plaque and it is being noticed as major causative bacteria of dental caries. Therefore, development of more effective, substantial and safe preventive agent against dental caries and periodontal disease is honestly required. The present study was designed to investigate the effect of chloroform extract(CE), n-butanol extract(BE),methanol extract(ME) and water extract(WE) of Caesalpinia on the growth, acid production, adhesion, and insoluble glucan synthesis of Streptococcus mutans. The CE, BE, ME and WE decreased the growth and acid production of S.mutans than that of control, especially, the ME was more effective than other extracts. The effect of CE, BE, ME and WE on the adherences to saliva-coated hydroxyapatite bead(S-HA) were evaluated. At the concentration of 2,000 ㎍/㎖, the CE showed 32% rate of bacterial adherence to S-HA, whereas, other extracts of the same concentration producedgreater than 50% rate. The CE and BE were significantly decreased the reduction rates of water insoluble glucan formation from sucrose by crude glucosyltransferase of S.mutans. Thus, the application of C. sappan can be considered a useful and a practical method for the prevention of dental caries.

The purpose of this thesis is to understand general artistic characteristics of Korean creative dance and examine literary and artistic sides of the theatrical art such as stage setting, lighting and costumes; musical and dramatic sides such as acting and production in order to escape from the lacking attempt to express resulting from our little understanding and passive attitude toward other genres of expression in present situation of dance art. In understanding the nature of other genres of an, I examined conceptual aspects and their functions and role effects. Then I found out some problems in the works of Korean creative dance performed on the stage when connecting with other arts. The most serious problem in performed works was that they failed to show genuine wholeness despite such nice tries and only offer spectacular effects by binding various specified genres into one large framework. Those problems appeared in connecting Korean creative dance with other arts are summarized as follows. ①All the individual genres of other arts connected with dance art were not harmonized coherently but showed such characteristics as synthetic presentation. ②Due to the exaggerated expressions of other arts, the power of expression of physical behavioral language was limited. ③When dance art was harmonized with other arts coherently, the creator's artistic philosophical judgement was in want. ④When conveyed to audience, the universal sensical system necessary in connecting dance art with other arts was lacking. Here, based on those problems above. I would like to show the direction to which we should progress connecting Korean creative dance with other arts. ①Creators are required to master the basic knowledge about unique expressive skills and characteristics of other genres necessary in connecting with other arts. ②In accordance with connecting with other genres of art, new dancing language suitable for new works should be developed profoundly. ③Creators who compose Korean creative dance should do their best to have their own artistic philosophical conviction necessary in connecting with other arts. ④They should try to develope universal sensical system characterized artistically on the whole for audience. ⑤Speciality in connecting with other arts, diversification of the subjects, and progressive experimentalism are required. Started with such sense of problem as above, this thesis pointed out several problems in connecting Korean creative dance with other torts and presented an absolute task to seek after a new way for the creation of dance characterized by various total-artistic quality at the threshold of 21st century.
