Purpose - This study was conducted to evaluate service quality, perceived value, and satisfaction in the performing arts in order to establish a system of relationships that predicts repurchase intention, which increasingly needs to be studied as the domestic performing arts market grows. Research design, data, and methodology - Another purpose of this study is to identify 'work-related factors' and 'performing-arts-related factors' in the performing arts industry, and to observe the influence of the core SQ factors expected to influence audiences' purchase intentions through perceived value and customer satisfaction. The empirical study to test the hypothesis was based on a review of the literature and employed the survey method; data were collected from a total of 500 audience members. Results - The major results of the analysis are as follows. First, in terms of quality factors affecting perceived value, literary quality, level, professionalism, and musical quality were shown to have a significant influence as key factors from the performing arts perspective, while reliability, convenience, and related costs were indicated to exert a significant influence as additional factors related to work. Secondly, the quality factors with a significant influence on customer satisfaction were literary quality, professionalism, and musical quality, which were shown to have a significant influence from the performing arts perspective, while only reliability was indicated to exert a significant influence on work-related factors. Third, perceived value was shown to have a strong positive (+) influence on customer satisfaction, with both perceived value and customer satisfaction exerting a significant influence on the revisit intention. Finally, according to the results a difference analysis with demographic variables, viewing variables as moderating variables, differences according to gender were indicated in the influence of literary value and lel on perceived value, and in the influence of convenience and professionalism on customer satisfaction as well. Also, in terms of the influence of perceived value on customer satisfaction, males were found to be more influenced than females. Conclusions - Based on the above results, the suggested implications of the present study are as follows. First, through the consideration of not only the crucial work perspective in performing arts services, which has been inadequate in the past, but the additional performance-related level, the previously unevenly distributed viewpoints were expanded for application. Second, in verifying the relationship between expanded quality factors and the factors that determine consumer behavior while simultaneously considering key factors and additional related factors, work-related service quality factors were shown to exert a stronger influence on perceived value and customer satisfaction than performance-related factors. Third, for service factors related to performance, the reliability factor exerts an influence on perceived value and customer satisfaction, requiring that a performance planner secure and manage diverse channels to immediately support customer requests in providing performance theater services.

Various forms of fermented soybean products are well documented for their health benefits. The efficacy of anti-obesogenic effect of Doenjang, one of the most commonly used seasonings in Korean cuisine, has been reported only in animal models; thus, an evaluation of Doenjang needs to be conducted in human studies. We aimed to test the hypothesis that Doenjang supplementation reduces body weight and changes body composition in overweight adults. A total of 51 overweight adults participated in this study. A group of males with BMI ${\geq}23kg/m^2$ and waist to hip ratio (WHR) ${\geq}$ 0.90, and a group of females with BMI ${\geq}23kg/m^2$ and WHR ${\geq}$ 0.85 were randomly assigned to either a Doenjang supplement (9.9 g dry/day) group or a placebo group for a 12-week randomized, double-blind and placebo-controlled study. Anthropometric parameters, abdominal fat distribution by computerized tomography (CT) and blood components were measured before and after the intervention period. After the 12-week study, the Doenjang supplementation group had significant reductions in body weight (kg), body fat mass (kg) and body fat (%) compared to the placebo group, the supplementation of Doenjang resulted in a significant reduction in visceral fat ($cm^2$), although no changes were observed in total and subcutaneous fat are as ($cm^2$), serum lipid profiles and dietary intakes. The present study demonstrated that daily supplementation of 9.9 g dry/day of Doenjang for 12 weeks reduces body weight and visceral fat in overweight adults.

A number of neurological syndromes(e.g. tardive dyskinesia) are developed as a consequence of chronic treatment with neuroleptics or antipsychotic agents. Despite the long and succesful use of phenothiazine derivatives and related agents in the treatment of certain states of mental disease, the mechanisms of these drugs are still poorly understood. One current hypothesis from extensive reviews is that these compounds might significantly interfere with the cyclic nucleotide system in brain (Levin and Weiss, 1977; Nowicki et al., 1991; Haley et al., 1992). Nitric oxide (NO), one of an interesting messenger molecule and aberrant transmitter, is believed to play a important role in biological functions of cyclic nucleotides in nervous system. It has been reported that calcium-dependent NO synthesis in endothelial cytosol is mediated by calmodulin which is supposed to be tightly related to pharmacological actions of antipsychotic agents. In the present study, the effect of several antipsychotic agents on the activity of NO synthesis and formation of cyclic GMP were investigated. These agents inhibited both the formation of $[^3H]L-citrulline$ and that of $[^3H]cyclic$ GMP by concentration-dependent manner, and their inhibiting patterns are so similar to that of calmodulin antagonist.

The physicochemical properties of clay minerals have been investigated at the atomistic to nano scale. The microscopic studies are often challenging to perform by using experimental approaches alone. In particular, hydroxyl groups of octahedral sheets in 2:1 clay minerals have been hypothesized to impact the sorption process of metal cations; however, X-ray based techniques alone, a common tool for mineral structure examination, cannot properly test the hypothesis. The current study has examined whether computational mineralogy techniques can be applied to examine the hydroxyl structures of clay minerals. Based on quantum-mechanics and molecular-mechanics computational methods, geometry optimizations were carried out for representative dioctahedral and trioctahedral phyllosilicate minerals. Both methods well reproduced the experimental lattice parameters; however, for structural distortion occurring in the tetrahedral or octahedral sheets, molecular mechanics showed significant deviations from experimental data. The orientation angle of the hydroxyl with respect to (001) basal plane is determined by the balance of repulsion between the hydroxyl proton and Si cations of tetrahedral sites; the quantum-mechanics method predicted $25-26^{\circ}$ for the angle, whereas the angle predicted by the molecular-mechanics method was much higher by $10^{\circ}$ (i.e., $35^{\circ}$). These results demonstrate that computational mineralogy techniques are a reliable tool for clay mineral studies and can be used to further elucidate the roles of hydroxyls in metal sorption process.
