  • Purpose - Pleasing ambient colors, music, scent, layout and salespeople are hypothesized to positively impact shoppers' perceptions about the atmosphere of a store. Few studies on the interactive effect of these atmospheric factors have earlier been undertaken. This paper looks at the interactive effect of color on the other predictor variables. Research design, data, and methodology - This study is from field locations in the shopping malls located in Delhi NCR. A descriptive study was undertaken to decipher the interactive effect of color with music, scent, layout and salespeople. Moderation of color on music, scent, layout and salespeople is regressed on store atmospherics. The authors investigate the effects of color, light, music, scent, layout and salespeople on store atmospherics in a retail context. They also study the interactive effect of color with predictor variables which significantly influence the perception of store atmospherics. Results - The paper reveals that music, scent, layout and salespeople influence customer's perception about store atmospherics. The interactive effect of color with scent, layout and sales people influence customer's perception about store atmospherics significantly. It does not moderate with layout and music. Conclusions - Store color is important in predicting store atmospherics. Care is needed to ensure that the effects of different environmental stimuli match.

  • Dental professions are considered high risk for contracting hepatitis infection. In Korea, many patients are hepatitis B virus carriers. HBV are most efficiently transmitted by blood. Root canal treatment, as in cases of acute pulpitis always accompanied by contaminated blood. Therefore it is absolutely necessary to use irrigation solutions having strong antiviral effect for prophylaxis both dental personnel and patients. The purpose of this study was to investigate the antiviral effect of seven root canal irrigation solutions by radioimmunometric test. The solutions were 5% sodium phyochlorite, 5% cresol, 2% glutaraldehyde, 3% hydrogen peroxide, 0.05% chlorohexidine, 10% iodine, and 70% isoprophyl alcohol. Each irrigation solutions was mixed with serum preparated from HBsAg positive patients and sera were diluted to 1:1. 1:4. 1:20 and 1:100. Percentage of radioactivity was assayed with AUK(Sorbin biomedica, Italy) and COBRA(Packwood Instrument company, USA). Sodium hypochlorite and glutaraldehyde showed most strong antivral activity against HBsAg. Isoprophyl alcohol had moderate antiviral effect and the effect and the effect was increased especially in 1:4 solution. Hydrogen peroxide exihibited very weak aintivral activity. Cresol, chlorohexidine, and iodine exhibited little antiviral activity.

  • Contemporary biomedical data often involve an ill-posed problem owing to small sample size and large number of multi-collinear variables. Partial least squares (PLS) method could be a plausible alternative to an ill-conditioned ordinary least squares. However, in the case of a PLS model that includes a random-effect, how to deal with a random-effect or mixed effects remains a widely open question worth further investigation. In the present study, we propose a modified multivariate PLS method implementing mixed-effect model (PLSM). The advantage of PLSM is its versatility in handling serial longitudinal data or its ability for taking a randomeffect into account. We conduct simulations to investigate statistical properties of PLSM, and showcase its real clinical application to predict treatment outcome of esthetic surgical procedures of human faces. The proposed PLSM seemed to be particularly beneficial 1) when random-effect is conspicuous; 2) the number of predictors is relatively large compared to the sample size; 3) the multicollinearity is weak or moderate; and/or 4) the random error is considerable.

  • Purpose - This study aims to investigate the factors (experience value, social capital, cultural capital) affecting users' engagement in UGC platform, and to examine their effect on relationship commitment. The study further attempted to confirm the moderating effect of the need for self-expression. Design/methodology/approach - Data was collected from 230 UGC users through a survey, and the study performed a structural equation model analysis to validate the conceptual model which contains five research hypotheses. Findings - The study found that only service value, one of experiential values, has a significant positive (+) effect on customer engagement and that social capital and cultural capital also have a significant positive (+) effect on customer engagement In addition, customer engagement in the UGC platform was found to have a significant positive (+) effect on the relationship commitment. However, the need for self-expression did not moderate the relationship between customer engagement and relationship commitment. Research implications or Originality - Marketing strategies that can strengthen UGC users' engagement factors can lead up to follow-up research, which finds ways to improve not only users' engagement but also sustained relationship with the UGC platforms.

  • Various kinds of positive effects of green tea extracts had been studied for long time which included anti-inflammation, anti-aging, and cardiometabolic effects. Although topical steroid and non-steroidal calcineurin inhibitors may control clinical symptoms of allergic contact dermatitis, some of patients also present allergic reaction to these topical agents. Therefore, we have tried green tea extracts for managing this skin disorder with expectation of anti-inflammatory effect without potential side effects including skin irritation and toxic responses. The toxicity test of green tea extract also did not show any sign of irritation in the skin throughout the test period. Moderate severity of allergic contact dermatitis presented satisfactory clinical outcome at second week follow-up which was final visit of outpatient. This result mean that green tea extract has a positive effect for managing allergic contact dermatitis but its potency and efficacy seem to be so not strong enough to control moderate severity allergy skin lesion. In this pilot study, we were able to conclude that green tea cell extracts might be applied for potential anti-inflammatory soaking without skin toxicity.

  • Objectives : This study sought to examine relationships between alcohol drinking and cardiovascular disease mortality and all-cause mortality. Methods : From March 1985 through December 1999, 2,696 males and 3,595 females aged 55 or over as of 1985 were followed up for their mortality until 31 December 1999. We calculated the mortality risk ratios by level of alcohol consumption. Among the drinker, the level of alcohol consumption was calculated by the frequency of alcohol comsumption and the type of alcohol. Cox proportional hazard model was used to adjust for confounding factors. Results : Among males, compared to abstainer, heavy drinker had significantly higher mortality in all cause(Risk ratio=1.35), cardiovascular disease(Risk ratio=1.52) and cerebrovascular disease(Risk ratio =1.66). Although not significant, moderate drinker had lower ischemic heart disease mortality(Risk ratio =0.38). Among females, there was no statistically significant association between alcohol comsumption and mortality. Conclusion : The results of this study suggest that alcohol drinking has harmful effect on all-cause mortality, cardiovascular disease mortality and cerebrovascular disease mortality among males, especially in heavy drinker among males. Minimal evidence on protective effect for cardiovascular disease mortality in low or moderate drinker is observed.

  • In order to know the toxic effect and carcinogenic activity in rats and mice fed with juice of Korean native Petasites japonicus Maxim of its pellet(4% or 8%) which were dried, milled and mixed with basal diet, the investigations were carried out by macroscopy and histopathology. Macroscopically, although remarkable changes were not observed in the liver of mice, there were slight to moderate swelling of rat livers in the whole groups at 12 to 14 weeks after feeding and milky spots in rats fed with its juice and 8% pelleted Petasites japonicus Maxim diet and a normal diet for 1 week alternatively for 14 weeks. Moreover, moderate to severe swelling and milk spots were recognized in livers of all rats fed with its juice and 8% pellet or 8% pelleted Petasites japonicus Maxim for 16 weeks. But, in cases of rats fed with its juice and 4% pellet or 4% pelleted Petasites japonicus Maxim, only swelling of livers was recognized moderately or severely. Histopathologically, major lesions were found in livers of both rats and mice. There were congestion, hemorrhage, fatty change, focal necrosis, megalocytosis and hyperplasia of endothelial cell in livers of mice and rats, the additional lesions such as proliferation of bile duct and nodular regeneration with diffuse regenerating cells were seen in livers of rats. In addition, preneoplastic lesions, the areas of milky spots macroscopically, were observed in livers of rats fed with Petasites japonicus Maxim for 14 to 16 weeks. In a few cases, haemangioendothelial sarcoma in livers was detected in rats fed with Petasites japonicus Maxim for 16 weeks. Petasites japonicus maxim growing naturally in Korea seem to exhibit toxic effect especially in liver and it contained a causative agent of primary liver tumors.

  • The growth-inhibitory activity of Cassia tora seed-derived materials against seven intestinal bacteria was examined in vitro, and compared with that of anthraquinone, anthraflavine, anthrarufin, and 1-hydroxyanthraquinone. The active constituent of C. tore seeds was characterized as quinizarin, using various spectroscopic analyses. The growth responses varied depending on the compound, dose, and bacterial strain tested. At 1 mg/disk, quinizarin exhibited a strong inhibition of Clostridium perfringens and moderate inhibition of Staphylococcus aureus without any adverse effects on the growth of Bifidobacterium adolescentis, B. bifidum, B. longum, and Lactobacillus casei. Furthermore, the isolate at 0.1 mg/disk showed moderate and no activity against C. perfringens and S. aureus. The structure-activity relationship revealed that anthrarufin, anthraflavine, and quinizarin moderately inhibited the growth of S. aureus. However. anthraquinone and 1-hydroxyanthraquinone did not inhibit the human intestinal bacteria tested. As for the morphological effect of 1 mg/disk quinizarin, most strains of C. perfringens were damaged and disappeared, indicating that the strong activity of quinizarin was morphologically exhibited against C. perfringens. The inhibitory effect on aflatoxin $B_1$ biotransformation by anthraquinones revealed that anthrarufin ($IC_50,\;11.49\mu\textrm{M}$) anthraflavine ($IC_50,\;26.94\mu\textrm{M}$), and quinizarin ($IC_50,\;4.12\mu\textrm{M}$), were potent inhibitors of aflatoxin ${B_1}-8,9-epoxide$ formation. However, anthraquinone and 1-hydroxyanthraquinone did not inhibit the mouse liver microsomal sample to convert aflatoxin $B_1$ to aflatoxin ${B_1}-8,9-epoxide$. These results indicate that the two hydroxyl groups on A ring of anthraquinones may be essential for inhibiting the formation of aflatoxin ${B_1}-8,9-epoxide$. Accordingly, as naturally occurring inhibitory agents, the C. tora seed-derived materials described could be useful as a preventive agent against diseases caused by harmful intestinal bacteria, such as clostridia, and as an inhibitory agent for the mouse liver microsomal conversion of aflatoxin $B_1$ to aflatoxin ${B_1}-8,9-epoxide$.
