The aim of this study is to examine the influence of job stress and teacher efficacy on early childhood teachers' job satisfaction levels. Data from 321 early childhood teachers working in kindergarten and child-care centers located in Incheon metropolitan city were collected. The data was analyzed by means of the SPSS 18.0 package. The results of this study were as follow; first, job stress was negatively correlated with job satisfaction. Job satisfaction levels were positively correlated with teacher efficacy. Secondly, job stress had a negative influence on job satisfaction levels. Teacher efficacy had a positive influence on job satisfaction levels. Thirdly, job stress had a directly negative influence on job satisfaction levels. It was also revealed that teacher efficacy had an indirect effect on the relationship between job stress and job satisfaction levels.

The Purpose of this study is to investigate the effects of the perceived luxury characteristic and consumer's conspicuous consumption on the fashion luxury involvement. The subjects were Korean 443 women from 20's to 50's living in Seoul. The reliability analysis, confirmatory factor analysis and structural equation analysis by AMOS 4.0 were used for statistics analysis. The results are as follows; 1) The perceived aesthetic taste and luxurious aspect of fashion luxury directly influence on fashion luxury involvement through hedonic consumption value. 2) The perceived luxurious aspect and traditional value of fashion luxury directly influence on negative luxury consumption value, but negative consumption value does not influence on fashion luxury involvement. 3) The well-known brand orientation, face-saving consumption, and value orientation directly influence on fashion luxury involvement.

This study examines the value, knowledge and sustainable consumption behavior of fashion consumers. The study shows that universalism/harmony, security/benevolence, power, and tradition/faith have positive effects on buying/usage behavior; however, hedonism/wealth has a negative effect. Stimulation/self-direction and universalism/harmony positively influence boycott behavior; however, power has a negative influence. Universalism/harmony and politeness have positive impacts on care/disposing behavior. Consumer knowledge about fashion related environmental problems, labor practices, ethical issues and sustainable environment knowledge influence sustainable buying/usage behavior; in addition, knowledge about ethical issues and sustainable environmental problems positively influence boycott and care/disposing behavior. Moreover, there were significant differences in values, knowledge, and consumption behavior by age.

The purpose of this study was to investigate the influence of the classroom climate perceived by children on the onlooker type in bullying. The data were collected from 236 elementary school children. The results of this study were as follows; First, the classroom climate that influence onlooker type was personal development dimension and among of the all, competition had important positive effect on onlooker type. Second, the classroom climate that influence onlooker type was interpersonal relation dimension and among of the all, the democratic climate had important negative effect on onlooker type. Third, the democratic classroom climate influenced negative effect on self-defense and indifference and positive effect on mutual fault among the onlooker types.

This study examined the influence of ESG performance on the firm value of Chinese equipment manufacturing companies over the period from 2011 to 2020. The analysis indicated that while ESG performance exerted a negative influence on firm value, this impact was not statistically significant. These findings substantiate the Institutional Difference Hypothesis (IDH), which posits that country-specfic institutional variations sifnificantly shape the strategic decision-making of organizations. When disaggregating the three components of ESG, variations in the results were observed both for overall ESG performance and for each individual dimension. Of the three dimension elements, the environmental (E) and governance (G) facets had a negative bearing, whereas the social (S) facet had a positive influence. Notably, only the governance dimension (G) demonstrated a statistically significant influence. These outcomes affirm the institutional difference hypothesis, illustrating divergent results across distint ESG dimensions.

This work evaluates the influence of negative stiffness on the performances of various vehicle suspension systems, and proposes a re-centering negative stiffness device (NSD). The re-centering NSD consists of a passive magnetic negative stiffness spring and a positioning shaft with a re-centering function. The former produces negative stiffness control forces, and the latter prevents the amplification of static spring deflection. The numerical simulations reveal that negative stiffness can improve the ride comfort of a vehicle without affecting its road holding abilities for either passive or semi-active suspension systems. In general, the improvement degree of ride comfort increases as negative stiffness increases. For passive suspension system, negative stiffness brings in negative stiffness feature in the control forces, which is helpful for the ride comfort of a vehicle. For semi-active suspensions, negative stiffness can alleviate the impact of clipped damping in semi-active dampers, and thus the ride comfort of a vehicle can be improved.

The purpose of this study was to analyze the effect of adjacentroads on the concentration of negative air ions in urban neighborhood park. The measured factors were negative air ion concentration, positive airion concentration, airtemperature,relative humidity, wind speed, green formation volume factor (GVZ) and distance from highway and general road. The mean negative air ion concentration was $206ea/cm^3$ and the positive air ion concentration was $416ea/cm^3$ in the influence zone of roads. On the other hand, the mean negative air ion was $339ea/cm^3$ and the positive air ion was $229ea/cm^3$ in the unaffected zone of roads, which are inner areas of the park. The difference of the negative air ion concentration according to the influence of the road was statistically significant. The negative air ion concentration model was presented by integrating the correlation analysis with the influence factors, and the explanatory power of the model was increased by adding the influence factor of the road.

The purpose of this study was to obtain data on the contribution of job characteristics (work, autonomy, reward, community, fairness, value) towards job burnout (emotional exhaustion, cynicism), job engagement (vigor, dedication, absorption) and turnover intention in school foodservice employees. Typically, 594 school foodservice employees in the Busan area participated in our survey. Workload (${\beta}=-0.512$, p<0.001) had the highest negative influence on emotional exhaustion, whereas reward (${\beta}=-0.216$, p<0.001) and community (${\beta}=-0.214$, p<0.001) had the highest negative influence on cynicism. Community (${\beta}=0.305$, p<0.001) and workload p<0.001) had the highest positive influence on vigor. Community (${\beta}=0.261$, p<0.001) and (${\beta}=0.238$, p<0.001) had the highest positive influence on dedication. (${\beta}=0.287$, p<0.001) and community (${\beta}=0.224$, p<0.001) had the highest positive influence on absorption. Workload (${\beta}=-0.195$, p<0.001) and community (${\beta}=-0.182$, p<0.001) had the highest negative influence on turnover intention. Overall, the results show that job characteristics are very important factors affecting foodservice employee's burnout, engagement, and turnover intention. So should try to reduce the employees' workload and increase the rewards for them along with activating communication among each other.
