  • Culture supernatants of splenocytes from C57BL/6 mice were exposed to 0.3, 1.0, and 3.0 ${\mu}g/ml$ cordycepin plus 3.0 ${\mu}g/ml$ lipopolysaccharide (LPS) to investigate the effects of cordycepin (3'-deoxyadenosine) on the production of inflammatory cytokines. Coadministration of 3.0 ${\mu}g/ml$ cordycepin with LPS in cultured murine spleen cells significantly diminished expression of the inflammatory cytokines tumor necrosis factor-${\alpha}$ and interleukin-6 (IL-6) in a time-dependent manner. Expression of the inflammatory cytokine IL-17A was substantially downregulated in a timeand concentration-dependent manner at all cordycepin concentrations. These findings suggest that cordycepin downregulates the immediate hypersensitivity reaction stimulated by LPS.

  • A gene, npl, encoding neopullulanase from Paenibacillus sp. KCTC 8848P was cloned and expressed in Escherichia coli. It consisted of an open reading frame of 1,530 bp for a protein that consisted of 510 amino acids with a molecular weight of 58,075 Da. The deduced amino acid sequence of the neopullulanase gene had $92\%$ identity with the neopullulanase of Bacillus polymyxa. The npl gene was also expressed in Saccharomyces cerevisiae secreting Schwanniomyces occidentalis glucoamylase (GAM1) under the control of the yeast actin gene (ACT1) promoter. Secretion of the neopullulanase was directed by the yeast mating pheromone ${\alpha}$ -factor ($MF{\alpha}1$) prepro region. Enzyme assays confirmed that co-expression of npl and GAM1 enhanced starch and pullulan degradation by S. cerevisiae.

  • To screen for an anti-yeast substance (AYS), many bacteria were isolated from soil and a strain AY2000 was selected. The strain AY2000 was identified as Rahnella aquatilis by morphology, biochemical properties, and 16S r-RNA nucleotide sequence analyses. The strain AY2000 showed anti-yeast activity against Candida albicans and Saccharomyces cerevisiae, whereas R. aquatilis ATCC33071 as a type strain did not show the activity against the yeasts under the same condition. The growth of yeast cell was significantly inhibited by AYS produced by the strain AY2000, as shown by optical density and MTT assay. The minimum inhibitory concentration (MIC) of the AYS against S. cerevisiae and C. albicans at $28^{\circ}C\;was\;20{\mu}g/ml\;and\;60{\mu}g/ml$, respectively. The MIC of AYS against hyphae of C. albicans at $37^{\circ}C\;was\;600{\mu}g/ml$. Scanning electron microscopic analysis revealed that yeast cells treated with AYS had an irregular form with a wrinkled and rough surface.

  • Objectives: The purpose of this study is to investigate whether the ethical climate affects the job satisfaction of the clinical dental hygienists. Methods: A self-reported questionnaire was filled out by 207 dental hygienists. The data were analyzed by t-test or one-way ANOVA, multiple regression analysis, and Pearson's correlation analysis using IBM SPSS Statistics 19.0 program. Results: The factors affecting the job satisfaction of the general and ethical climate were the work experiences, the completion of vocational ethics education, the self interest type, the friendship type, the rule and the procedure type. When working experience and vocational ethics education are completed, self interest type and friend type have improved job satisfaction as the score increases, while job satisfaction is lowered as the rule and procedure type are increased. Conclusions: Since healthy ethical climate correlates with job satisfaction, it is necessary to establish an ethical climate in order to improve the job satisfaction of clinical dental hygienists. Efficient and stable management of ethical climate within dental clinics can be achieved when mutual interests are emphasized and respected rather than obedience is empathized to hospital regulations, procedures and policies.

  • The purpose of this research is to investigate the influences of service experience and brand reputation on intention by word of mouth(WOM) when consumers get experiences at beauty salon. We made 2(valence of service experience: positive/negative) ${\times}$ 2(brand reputation level: high/low) subjects experimental design in order to find reason that there is a significant difference of intention by word of the mouth between positive experience condition and negative experience condition. Also we tried to find the interaction of two factors. To test our hypothesis, an experiment was performed on 68 university students in seoul area. Specifically, we used 2-way ANOVA and planned contrast method through SPSS 12.0 procedure. As a result, a two-way ANOVA demonstrated a significant main effect of service experience, which means that people more intend to make WOM when they experience a negative service than a positive service. Also the ANOVA showed a significant interaction effect between service experience and brand reputation, which represents that people more intend to make WOM for high-reputed(low-reputed) brand than low-reputed(high-reputed) brand when they encounter negative(positive) services.

  • Allylaliphatic carboxylate oligomers were prepared from polymerization giving allyl aliphatic carboxylates in the presence of potassium persulfate in methanol and the ${\alpha}-sulfonation$ of these allyl aliphatic carboxylates oligomers were carried by direct addition of dry sulfur trioxide. The dispersing performance of oligomer type anionic surfactants and SDS in the aqueous suspension of $Fe_{2}O_{3}$ and $Tio_{2}$ particles were evaluated by particle size distribution and ${\zeta}-potential$ measurement. As results, the particles of $Fe_{2}O_{3}$ and $Tio_{2}$ were flocculated by addition of small amount of oligomer type anionic surfactants and SDS, then the flocks redispersed by more addition oligomer type anionic surfactants and SDS. The dispersion and flocculation were observed in lower concentration range of oligomer type anionic surfactants than SDS.

  • Mulberry extracts can be incorporated into skin-whitening products. The compound attributed to lighten the skin is arbutin, a form of hydroquinone that inhibits melanin release by suppressing the tyrosinase enzyme. For the cosmetic applications, the physiological effects of mulberry (Morus alba) extracts were investigated. The water soluble fraction of mulberry contains higher amount of protein (16.28~4.47%) in contrast to fat (1.55~1.41%). In addition, the fraction abundantly contains succinic acid (972.4-275.8 mg/g) and phosphoric acid (1,628.4-121.9 mg/g) in different parts of mulberry. The free radical scavenging ability in water soluble fraction was found to display remarkable effects in comparison with methanol and ethyl acetate fraction. The ethyl acetate-soluble of root and leaf showed remarkable tyrosinase inhibition activity by IC 50 (${\mu}g/ml$). The anticancer activity of methanol fraction obtained from mulberry using human cancer cell lines showed growth inhibition effect (270.14 mg/ml in Calu-6 cells, 295.29 mg/ml in HCT-116, and 332.29 mg/ml in MCF-7 cells, respectively). Based on the results, Morus alba extracts include cosmetic ingredients with antioxidizing and whitening properties.

  • Objective : The purpose of this report is to know the effect of oriental medical treatments on acute allergic contact dermatitis with multiple nummular eczema. Methods : We treated a 34-years-old woman patient with acute allergic contact dermatitis on face and multiple nummular eczema on both arm, right ankle and left inguinal region by Korean medicine. After Korean medical treatment for 42 days in hospital, we measured the decrease of exudation and pruritis as well as recovery of skin damages. We recorded pictures of changes on symptoms. Results & Conclusion : The symptoms of ACD and nummular eczema were significantly improved except scars. Exudation and pruritis were disappeared and skin damages were almost recovered until discharge from hospital. After 20 days we could confirm the symptoms were clearly disappeared. Thus Korean medical treatments are effective on ACD and nummular eczema.
