The purpose of this study was to examine the mediating role of attitude, subjective norm, and perceived behavioral control on the relationships between past behavior and customers' intention to engage in voice of dissatisfaction responses. Results of the study demonstrated that the inclusion of past behavior improved the predictability of the voice of dissatisfaction response intentions. Furthermore, the mediating analyses indicated that the influence of past behavior was mediated by mediator. In the contests of voice behavior, the effect of past behavior on intention was not mediated by attitude and perceived behavioral control. Meanwhile, subjective norm mediated the relationship between past behavior and the intention to engage in voice behavior.

Helianthus tuberosus is perennial plant as Compositae family and is shown various physiological activities such as analgesic, antipyretic, anti-inflammatory, anti-fungal, anti-spasmodic, aperient, cholagogue, diuretic, spermatogenic, stomachic, and tonic effects. In this study, we investigated the antidiabetic and anti-inflammatory effects of pancake mixture powder (PM) supplemented with H. tuberosus (PMH) in rat skeletal muscle L6 cells and murine macrophage RAW 264.7 cells, respectively. PM and PMH inhibited in vitro α-glucosidase activity. Glucose consumption was increased by PM and PMH without cytotoxicity in rat myoblast L6 cells. Western blot analysis revealed that PM and PMH down-regulated glycogen synthase kinase (GSK)-3β activation in L6 cells. PM and PMH inhibited inflammatory mediator, nitric oxide (NO) production without cytotoxicity in LPS-induced RAW 264.7 cells. The anti-diabetic and anti-inflammatory effects of PMH was more stronger than those of PM. Anti-diabetic and anti-inflammatory effects of PMH would be due to functional characteristics of the supplemented H. tuberosus and the presence of garlic and onion used as ingredients of PM. Taken together, our results that addition of functional materials such as H. tuberosus in product has synergic effects and PMH is potential candidate for treatment of diabetes through inhibiting inflammation.

This study examines the relationship between a mother's psychological well-being and children's problematic behavior(withdrawal, depression anxiety, aggression and emotional instability). In order to expand the study on the relationships, special attention was given to the possible mediator effects of mother's coping style with children's negative emotions. The subjects were 305 mothers with children 4-5 years old residing in the cities of Cheonan and Seongnam. It was found that mother's psychological well-being was significantly related to the level of children's withdrawal, depression anxiety, aggression and emotional instability. The mother's coping style with children's negative emotions were also significantly related to the mother's psychological well-being. In addition the mother's coping style with children's negative emotions was found to be a significant mediator of the relationship between mother's psychological well-being and children's. This was especially so for internal problems behavior as like withdrawal, depression anxiety and emotional instability that were perfectly mediated by the mother's coping style with children's negative emotions. Aggression, external problems behavior was partially mediated by the mother's coping style.

Free radical scavengers or quenching agents for reactive oxygen species (ROS) present in consumable fruits, vegetables, and beverages have received considerable attention as potential antioxidants, and thus uses for treatment of several human diseases. In this study, grapevine shoot extract (GSE) containing high concentration of resveratrol and viniferine was evaluated for antioxidant potential and inhibition of pro-inflam-matory mediator production. Utilizing 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity and xanthine oxidase (XOD) inhibition assay the GSE showed inhibitory effects of DPPH radical scavenging and XOD activity with the $IC_{50}$/ values of 34.5 and 155 $\mu\textrm{g}$/ml, respectively. In addition, GSE also exhibited the inhibition of prostaglandin E$_2$ (PGE$_2$) and nitric oxide (NO) production in lipopolysaccharide (LPS)-induced mouse macrophage RAW264.7 cells with the $IC_{50}$/ value of 6.4 and 14.5 $\mu\textrm{g}$/ml, respectively. This result suggests that grapevine shoot extract has the potential activity as a natural antioxidant or antiinflammatory agent.

Purpose - This study investigates the effect of strategic orientation on market performance with emphasis on the mediative role of innovation capability, economic value and relational value in food producer companies. Research design, data, and methodology - In this descriptive study, a population of 244 managers and employees of Food industry companies in Tehran were investigated. The respondents filled a questionnaire on strategic orientation, innovation capability, economic value, relational value and market performance, during January to August 2018. Reliability and validity were evaluated by Cronbach's alpha coefficient and confirmatory factor analysis. To analyze the data, Spearman's correlation coefficient and structural equation modeling were used by SmartPLS software. Results - Effects of competitor's orientation and technology orientation on all three intermediary variables were positive and significant. The effect of customer orientation on innovation and economic value was positive and significant, but the effect of customer orientation on the value of the relationship was insignificant. Furthermore, entrepreneurial orientation has a positive and significant effect on innovation capability. The effects of three mediator variables on market performance are positive and significant. Conclusions - As the relationship between the mediator variables and market performance were positive and significant, companies should have a comprehensive plan of focus on strengthening these variables.

Purpose: This study aimed to identify the mediating effects of career motivation and job-esteem and the effect of the nursing work environment on intention to stay among hospital nurses. Methods: Data were collected from 289 nurses working at an advanced general hospital. The research model design was based on the PROCESS macro proposed by Hayes and analyzed using SPSS 24.0 program. Results: The results showed a positive correlation between intention to stay and nursing work environment (r = .19, p = .001), career motivation (r = .34, p < .001), and job-esteem (r = .37, p < .001). Nursing work environment (B = 0.34 [.09~.59]) and job-esteem (B = 0.27 [.04~.49]) had a direct effect on intention to stay. There was a two-mediator sereal mediation effect of career motivation and job-esteem. The nursing work environment showed a significant effect on the intention to stay among hospital nurses through career motivation and job-esteem. Conclusion: In order to increase the retention rate of hospital nurses, it is suggested that government and medical institutions provide multifaceted support that can increase nurses' motivation for career development and recognition of the nursing profession through improvement of the nursing work environment.
