Expected consumer's consumption propensity affected by advertisement using media facade and how this advertisement can affect consumer response and advertising effectiveness will be examined practically. This research showed TV advertisement and media facade advertisement to each participants of research in order to evaluate consumer response and effectiveness of media facade advertisement and took a survey. Research result, positive response was observed that consumer who were exposed of media facade advertisement showed more positive cognition/emotional response than TV advertisement. And effectiveness of media facade is more than standard. However, product attitude was not statistically positive. Therefore, it can be said that media facade advertisement does not affect positively on product attitude, but it is effective on purchase intention. Next, consumer who is exposed of media facade advertisement showed little low correlation on cognition response and product attitude, but showed positive correlation on cognition response, purchase intention, emotional response and product attitude. Accordingly, more positive consumer's cognition and emotional response is, the higher advertisement effect can be observed. Last, positive result were not presented in consumer's consumption propensity in regards to rational/emotional response. This means that it is invalid to state that consumer response differs for consumer propensity. Through result of experiment, a statement that media facade is a new media that has various possibility as advertisement mediator had been proved. Especially, as it shows that positive effect exists regardless of consumer's consumption propensity, use of media facade as marketing means is reasonable for firm in order to increase satisfaction of consumer and brand value.

The purpose of this study is to investigate the effects of poverty on the psychosocial adjustment of adolescents. Particularly, this study seeks to examine the mediating effects of neighborhood environments and parental depression. The 2008 'the Korean Youth General Survey' data were utilized. We analyzed data from 2,218 adolescents between the ages of 12 and 18 and their parents. We defined poverty as the income-to-needs ratio, and measured neighborhood environment using the degrees of neighborhoods' disorder, attachment, cohesion, and informal social control. Adolescents' externalizing and internalizing problem behaviors were used as indicators of adolescents' psycho-social adjustment. Structural equation modeling was utilized as the major analytic method. This study found that adolescents in low income families were more likely to reside in disadvantaged and dangerous neighborhoods. More importantly, the results revealed that psychosocial adjustment of the adolescents was indirectly influenced by poverty through the mediators, neighborhood environment and parental depression. Based on the results, we discussed policy and practice implications, including various interventions that may improve parental mental health and neighborhood environment of low income communities.

The aim of this study was to determine key experiences of homestay guardians of unaccompanied minor Korean adolescents studying abroad in the United States through qualitative research method of grounded theory methodology. This study identified guardianship experiences and the process of adjustment to life with homestay students through in-depth interviews with 12 subjects who are Korean guardians in the United States. The results of this study classified "started with concern" as a category that leads guardians to start providing homestay accommodation, and "other's recommendation," "need for financial support," and "unexpectedly" as subcategories. This study identified "act as a mediator to resolve differences" as a key experience of guardians, and classified subcategories are "parental role" and "calculation of gains and losses" on a personal level; and "feel sorry for own children," "limited leeway of the family," and "formation of relationship between own children and homestay students" on a family level. Developed subcategories are "thirsty for attention," "vulnerability," "task on freedom and control," and "regrettable feeling in the absence of communication" with respect to relationship with students; "grade expectations," "one-way communication," "trapped between parents' and students' demands" in regard to relationship with parents; and "advice from school" in the aspect of school. "Cultural difference," "preparedness of students and parents," "age differences between guardian's children and students," "family support," "similar personalities," "guardian's motivation," and "parent's attitude" are subcategories that affect central phenomenon of guardians.

There has neither been enough research on how to approach the concept of active aging through an integrated view nor an examination to verify the relationship between preparation for old age and active aging in later life. Therefore, this research aims to verify that the elderly, who have prepared for their later life, affected their active aged life. In addition, by setting up self-efficacy and social support as mediator in the research model, this paper looks into the psycho-social resource mechanism of the relationship in depth. In order to verify the correlation of two variables, the Seoul welfare panel data, a mediating model structured by psycho-social resources created by Seoul welfare foundation in 2010, was used. The total sample size was a group of 1,492 elders aged over 65. When it came to our research methods, structured equation analysis was applied to verify the mediating effect and theoretical background. The results revealed that physical preparation, financial preparation, social preparation and leisure preparation directly affected their active aging level positively, thus, psycho-social resources showed a partial mediating effect between preparation for old age of the past and active aging level. The research implications are as follows. First, this research makes an effort to approach the concept of preparation for old age with an integrated perspective through making a construct by entire preparation types. Second, it will attempt to verify the relationship between preparation for old age in the past and active aging in terms of multi-dimension is meaningful. Third, this research reveals the function of psycho-social resource, self-efficacy and social support within the relationship. As far as the partial mediating effect is concerned, preparation for old age education for the middle-aged class should be modified as a decent field to enhance of the elderly.

The purpose of this study is to analyze the effects of emotional labor on job stress using emotional dissonance as a mediator. Emotional labor is classified into the deep acting and the surface acting, and job stress is classified into sub - variables of the lack of reward and the relationship conflict. We conducted an empirical analysis of 400 questionnaires collected mainly from actors living in Seoul and Gyeonggi provinces. The results of the analysis using SPSS v22.0 and Process macro v3.0 showed that only the surface acting had a significant effect on the lack of reward, and both the deep acting and the surface acting had significant effects on relationship conflict. Second, only the surface acting had a significant effect on emotional dissonance. Third, it has been shown that emotional dissonance has a significant positive effect on both the lack of reward and the relationship conflict. Fourth, the indirect effect of the surface acting on the job stress through mediating emotional dissonance was significant. Subsequent studies will likely require studies to find other mediators other than emotional dissonance or to analyze moderated mediation effect by introducing moderators.

Objectives : This study aimed to investigate the effects of resilience on posttraumatic stress symptoms and dissociation and whether depression mediates the relationships between resilience and posttraumatic stress symptoms and dissociation. Methods : A total of 115 firefighters participated in the study. Data were collected via the Life Events Checklist, Impact of Event Scale-Revised, Dissociative Experience Scale, Beck Depression Inventory, and Connor-Davidson Resilience Scale. Structural equation modeling and path analysis were applied to estimate the relationships between resilience, depression, posttraumatic stress symptoms, and dissociation. Results : Greater resilience was associated with lower posttraumatic stress symptoms and dissociation, and the relationship between them was fully mediated by depression. Conclusions : Specific aspects of depression may help explain the relationships between resilience and posttraumatic stress symptoms and dissociation. Tailored prevention programs and treatments based on resilience and depression may prevent posttraumatic stress symptoms and dissociation in firefighters and improve treatments outcomes among firefighters with posttraumatic stress symptoms and/or dissociation.

BACKGROUND/OBJECTIVES: Premenstrual syndrome (PMS) is a disorder characterized by repeated emotional, behavioral, and physical symptoms before menstruation, and the exact cause and mechanism are uncertain. Hyperprolactinemia interferes with the normal production of estrogen and progesterone, leading to PMS symptoms. Thus, we judged that the inhibition of prolactin hypersecretion could mitigate PMS symptoms. MATERIALS/METHODS: Hordeum vulgare L. extract (HVE), Chrysanthemum zawadskii var. latilobum extract (CZE), and Lomens-P0 the mixture of these extracts were tested in subsequent experiments. The effect of extracts on prolactin secretion at the in vitro level was measured in GH3 cells. Nitric oxide and pro-inflammatory mediator expression were measured in RAW 264.7 cells to confirm the anti-inflammatory effect. Also, the hyperprolactinemic Institute for Cancer Research (ICR) mice model was used to measure extract effects on prolactin and hormone secretion and uterine inflammation. RESULTS: Anti-inflammatory effects of and prolactin secretion suppress by HVE and CZE were confirmed through in vitro experiments (P < 0.05). Treatment with Lomens-P0 inhibited prolactin secretion (P < 0.05) and restored normal sex hormone secretion in the hyperprolactinemia mice model. In addition, extracts significantly inhibited the expression of pro-inflammatory biomarkers, including interleukin-1𝛽, and -6, tumor necrosis factor-𝛼, inducible nitric oxide synthase, and cyclooxygenase-2 (P < 0.01). We used high-performance liquid chromatography analyses to identify tricin and chlorogenic acid as the respective components of HVE and CZE that inhibit prolactin secretion. The Lomens-P0, which includes tricin and chlorogenic acid, is expected to be effective in improving PMS symptoms in the human body. CONCLUSIONS: The Lomens-P0 suppressed the prolactin secretion in hyperprolactinemia mice, normalized the sex hormone imbalance, and significantly suppressed the expression of inflammatory markers in uterine tissue. This study suggests that Lomens-P0 may have the potential to prevent or remedy materials to PMS symptoms.

BACKGROUND/OBJECTIVES: Schisandrae Fructus, the fruit of Schisandra chinensis Baill., has traditionally been used as a medicinal herb for the treatment of various diseases, and has proven its various pharmacological effects, including anti-inflammatory and antioxidant activities. In this study, we investigated the inhibitory effect of Schisandrae Fructus ethanol extract (SF) on inflammatory and oxidative stress in particulate matter 2.5 (PM2.5)-treated RAW 264.7 macrophages. MATERIALS/METHODS: To investigate the anti-inflammatory and antioxidant effects of SF in PM2.5-stimulated RAW 264.7 cells, the levels of pro-inflammatory mediator such as nitric oxide (NO) and prostaglandin E₂ (PGE₂), cytokines including interleukin (IL)-6 and IL-1β, and reactive oxygen species (ROS) were measured. To elucidate the mechanism underlying the effect of SF, the expression of genes involved in the generation of inflammatory factors was also investigated. We further evaluated the anti-inflammatory and antioxidant efficacy of SF against PM2.5 in the zebrafish model. RESULTS: The results indicated that SF treatment significantly inhibited the PM2.5-induced release of NO and PGE₂, which was associated with decreased inducible NO synthase and cyclooxygenase-2 expression. SF also attenuated the PM2.5-induced expression of IL-6 and IL-1β, reducing their extracellular secretion. Moreover, SF suppressed the PM2.5-mediated translocation of nuclear factor-kappa B (NF-κB) from the cytosol into nuclei and the degradation of inhibitor IκB-α, indicating that SF exhibited anti-inflammatory effects by inhibiting the NF-κB signaling pathway. In addition, SF abolished PM2.5-induced generation of ROS, similar to the pretreatment of a ROS scavenger, but not by an inhibitor of NF-κB activity. Furthermore, SF showed strong protective effects against NO and ROS production in PM2.5-treated zebrafish larvae. CONCLUSIONS: Our findings suggest that SF exerts anti-inflammatory and antioxidant effects against PM2.5 through ROS-dependent down-regulating the NF-κB signaling pathway, and that SF can be a potential functional substance to prevent PM2.5-mediated inflammatory and oxidative damage.

Most of the existing studies on the volume and valence of the eWOM (electronic word of mouth) about movies and box-office revenues were conducted using online actual data (secondary data) at Yahoo Movies, IMDB.com, Naver Movies, etc. However, it is difficult to grasp psychological variables from online actual data. Therefore, existing studies using online actual data could not identify the causal relationship among volume, valence and psychological variables. This study fills this gap in the literature. This study aims to examine the direct and indirect effects (i.e. mediating effect) of the volume and valence of online reviews about movies on purchase intention through review credibility as a mediator. We conducted a survey on the South Korean consumers and a structural equation modeling. The outcomes show that the total effects of both volume and valence are significant. In addition, volume has an indirect effect only (i.e. full mediating effect) on purchase intention through review credibility, but valence has both direct and indirect effects (i.e. partial mediating effect) on purchase intention through review credibility. The theoretical and practical implications for these results are presented.

The purpose of this study was to examine the relationship among potential job-related risks, emotional dissonance, and job turnover intention of caregivers at the long-term care facilities in South Korea, and to explore the potential mediator role of burnout in this association. For the study, survey data of 434 caregivers at long-term care facilities were collected and analyzed using structural equation modeling method. The results showed that high level of caregivers'perception of the potential job-related risks led to increased burnout and turnover intention of caregivers. Second, caregivers'burnout partially mediated the effect of the potential job-related risks on turnover intention. Third, the more caregivers experience emotional dissonance, the higher the possibility of caregivers'burnout. On the other hand, emotional dissonance of caregivers did not give significant direct impact on turnover intention. Burnout fully mediated the relationship between emotional dissonance and turnover intention of caregivers. Lastly, the more caregivers experience burnout, the higher possibility of turnover intention. Based on the results, researchers suggested possible intervention methods as well as preventive measures to reduce the turnover of caregivers at long-term care facilities.
