Growing environmental awareness around the world has made environmental issues increasingly important in business. While most past research has focused on consumers' sustainable morals and lifestyles as the main motivations for eco-friendly consumption, few studies have examined the effect of traditional marketing programs on sustainable consumption. In this study, the author posited that delicate visual cues in store retail environments, particularly visual cues of the store interiors, affect the ways consumers evaluate the brand. The author specifically tested the effect of visual congruence, or the perceived fit between brands and visual cues in retail atmospheres, on perceived brand image and trust. The results of the online survey of 622 U.S. consumers indicated that visual congruence has a significant positive effect on consumer trust in the brand. The author also hypothesized that environmental concerns would moderate the relationships. consumers' subjective environmental concerns do not moderate the positive effect of visual congruence on trust in the brand.

The aim of this study is to evaluate the incidence of white striping abnormality and its consequences on the quality traits of raw and processed turkey breast (chemical composition, color traits, and water holding capacity). In total, about 2300 breasts from 22 flocks were used to assess the incidence and 60 breasts to evaluate the quality traits. Our study showed that the total incidence of moderate and severe white striping was 61.3% out of them, moderate cases were 49.4%. Severe white striped turkey breast exhibited significantly lower protein content (21.1 vs. 23.2 and 23.16%, p<0.05) and higher fat content (2.3 vs. 0.77 and 1.76%, p<0.05) if compared to normal and moderate white striped breast respectively. Moreover, moderate and severe white striped meat showed significantly higher redness (a*) (2.98 and 3.14 vs. 1.48, p<0.05) and yellowness (b*) indexes (7.27 and 7.95 vs. 4.05, p<0.05) than normal meat, respectively.

As widely known major cause of tooth discoloration is red blood cell in dentinal tubules after tooth trauma and extirpation. Hemoglobin in the red cells easily conbine with hydrogen sulfide and change natural tooth color into dark brown. To confirm and compare the effect of bleaching agents test material was made as fellows: No. 40 paper points were soaked in blood and put into the oven for 24 hours to dry. Dried paper points were again soaked in diluted yolk by distilled water for a minute and kept the points for a week to get fully sulfide. Hydrogen peroxide (25%), Sodium hypochlorite (2%), Sodium hyposulfate (2%), Sodium perborate and mixture of Hydrogen peroxide (25%) and Sodium perborate were employed as bleaching agents. About 0.2ml of each medicaments were put into the small test tubes and blood soaked paper points were gently placed vertically with the apex downward and kept 24 hours in the oven ($37^{\circ}C$). Every 24 hours the medicaments were renewed at 24 and 48 hours. Following are the results of the study: 1. Significant bleaching effect was found on the case of hydrogen peroxide (25%) after 24 hours. The area above 2mm from apex also fully bleached after 48 hours. 2. A mixture of hydrogen peroxide and sodium perborate treated case showed moderate effect at 24 hours and significant effect at 48 hours. High portion of the point (above 2mm) was bleached satisfactory at 72 hours. 3. The effect of sodium perborate at 48 hours showed moderate and significant at 72 hours. 4. Sodium hypochlorite and sodium hyposulfate were weak agent in bleaching. At 72 hours case revealed moderate effect and influenced on high portion of the point very weak effect.

This paper aims to empirically analyze how competitive and cultural factors moderate the relationship between electronic word-of-mouth (eWOM) characteristics and sales in the US and Korean film industries. A conceptual model was developed based on the cue utilization theory (CUT) to analyze the role of cultural and competitive factors that moderate the relationship between three characteristics of eWOM (volume, valence, and variance) and movie sales. Data of 45 days of 163 films released in Korea and the US were collected and a total of 7,335 samples were analyzed by panel regression. As results, competitive factors enhanced the influence of the eWOM of a focal film and this moderating effect depended on the eWOM characteristics. It also revealed that the effect of eWOM had a greater effect on movie sales in Korea than in the US.

Purpose: To analyze data from an observational, prospective, cumulative registry study in 805 hypogonadal men stratified by mild or moderate-to-severe lower urinary tract symptoms (LUTS) according to International Prostate Symptom Score. Materials and Methods: A total of 412 men underwent testosterone therapy (TTh) with injectable testosterone undecanoate, 393 men served as untreated controls. Measures of urinary function, anthropometric and metabolic parameters were performed at least twice per year. Results: Data from 615 men with mild LUTS (253 treated, 362 untreated) and 190 with moderate-to-severe LUTS (159 treated, 31 untreated) were available. During a follow-up period of 8 years a significant improvement of LUTS was noted for all TTh-patients whereas the control-groups showed deterioration or fluctuation around initial values. Despite advancing age, TTh fully prevented worsening of symptoms. In parallel, a considerable improvement of anthropometric parameters, lipids and glycemic control, blood pressure, C-reactive protein, and quality of life was found. Moderate-to-severe LUTS was associated with worse cardiometabolic risk profile at baseline as well as worse cardiovascular outcomes during follow-up in comparison to mild LUTS. Effect size of TTh was more pronounced in men with moderate-to-severe than with mild LUTS. Conclusions: Correcting hypogonadism by TTh is highly effective and safe for improving LUTS in hypogonadal men. TTh may also improve cardiometabolic risk and major adverse cardiovascular events.

The purpose of this study was to investigate the effect of donning of a hard insole in patients with hallux valgus. Fourteen subjects were selected from patient with foot pain at Lee Chang-Heon Foot Clinic from August 4, 2000 to September 15, 2000. The hallux valgus angle and the first-second intermetatarsal angle were radiographically measured before and after donning the hard insole. Based on these two kinds of angles, a mild hallux valgus deformity group was characterized by the hallux valgus angle of less than 20 degrees, and a moderate hallux valgus deformity group was characterized by the hallux valgus angle of 20 to 40 degrees. After three weeks with the hard insole donned, the foot angles of the patients with hallux valgus were measured again. The data were analyzed by Wilcoxon signed ranks test, and the following results were obtained: 1) After the trial, both mild hallux valgus deformity group and moderate hallux valgus deformity group demonstrated that the hallux valgus angles were significantly decreased. 2) After the trial, mild hallux valgus deformity group demonstrated that the first-second intermetatarsal angle was significantly decreased. 3) After the trial, moderate hallux valgus deformity group demonstrated that the first-second intermetatarsal angle was not significantly decreased. The above findings revealed that according to donning hard insole, the hallux valgus angles of mild and moderate hallux valgus deformity groups and the first-second intermetatarsal angle of mild hallux valgus deformity group were significantly decreased. The results of this study have some limitation for generalization due to the limited number of subjects. Further studies are needed to evaluate the effect of hard insole on hallux valgus with more precise laboratory equipments and measurements in patients with hallux valgus.

The aim of the study is to show the results of complex shaking table experimental investigation focused on the response of two models of cylindrical steel tanks under mining tremors and moderate earthquakes, including the aspects of diagnosis of structural damage. Firstly, the impact and the sweep-sine tests have been carried out, so as to determine the dynamic properties of models filled with different levels of liquid. Then, the models have been subjected to seismic and paraseismic excitations. Finally, one fully filled structure has been tested after introducing two different types of damages, so as to verify the method of damage diagnosis. The results of the impact and the sweep-sine tests show that filling the models with liquid leads to substantial reduction in natural frequencies, due to gradually increasing overall mass. Moreover, the results of sweep-sine tests clearly indicate that the increase in the liquid level results in significant increase in the damping structural ratio, which is the effect of damping properties of liquid due to its sloshing. The results of seismic and paraseismic tests indicate that filling the tank with liquid leads initially to considerable reduction in values of acceleration (damping effect of liquid sloshing); however, beyond a certain level of water filling, this regularity is inverted and acceleration values increase (effect of increasing total mass of the structure). Moreover, comparison of the responses under mining tremors and moderate earthquakes indicate that the power amplification factor of the mining tremors may be larger than the seismic power amplification factor. Finally, the results of damage diagnosis of fully filled steel tank model indicate that the forms of the Fourier spectra, together with the frequency and power spectral density values, can be directly related to the specific type of structural damage. They show a decrease in the natural frequencies for the model with unscrewed support bolts (global type of damage), while cutting the welds (local type of damage) has resulted in significant increase in values of the power spectral density for higher vibration modes.
