This study engaged food-service industry workers in Busan (casual dining restaurants and buffets) to investigate the moderating effect of job satisfaction on the influence of emotional labor on turnover intention and job burnout. To accomplish the goal of this study, the statistical programs SPSS 21.0 and AMOS 21.0 were employed for frequency analysis, factor analysis, reliability, and confirmatory factor analysis of responses from f 278 respondents. An examination was conducted to prove the hypothesis based on a structural equation model. There are two sub factors of emotional labor, surface acting and deep acting. According to the result of this study, surface acting has a positive influence (+) on job burnout (exhaustion) while deep acting has a negative influence(-). In addition, job burnout showed a positive influence (+) on turnover intention. It has been revealed that job satisfaction has a moderating effect on the path from deep acting to job burnout. Having considered that job burnout of food-service workers in Busan was related to deep acting, one of sub factors of emotional labors, promoting deep acting appears to be the way of reducing both job burnout and the number of people with turnover intention. Therefore, it is necessary for restaurant owners and CEOs to implement employee training and improve employee benefits in order to promote the deep acting of their employees.

The objective of this study was to set the optimal extraction condition of flavonoids from onion peels as a by-product generated from the onion industry without suitable processing. Four independent variables, affecting extraction conditions, which are solvent concentration ($X_1$), extraction temperature ($X_2$), pH of the solvent ($X_3$), and solvent ratio to onion peel ($X_4$) were optimized using response surface methodology (RSM). A model equation obtained from RSM is 0.772 of R-square and 0.278 of lack of fit (p>0.05) for the optimal extraction conditions. From the ridge analysis, the conditions flavoring the highest extraction were solvent concentration (v/v) of 70%, extraction temperature of $40^{\circ}C$, extraction solvent pH of 5.3, and a solvent ratio to onion peel ratio of 1:63 (w/v). The flavonoid content obtained under optimal conditions showed 302.63 mg/g, which is 1.12 times higher than the prediction value.

Flowability and strength with curing time of controlled low-strength material (CLSM) are required differently according to the construction purpose. In this paper, the flowability and strength were estimated from the mixing ratio of CLSM using multiple regression analysis to design the CLSM. The flow values and strength at 12 hrs and 7days were measured in accordance with the mixing ratio of CLSM which consists of 7 different materials, such as CSA expansive agent, ordinary Portland cement, fly ash, sand, silt, water, and accelerator. The multiple regression was performed with the proportions of each material of CLSM as independent variables and the measured properties as dependent variables using SPSS Statistics 23 which is a statistical analysis program. The regression coefficients were estimated from the first to third order equation models for the materials. From the results, the third order model for the flow values and the first order models for 12hrs and 7days strength are the most appropriate models. This study suggests that the mixing ratio required for constructions may be effectively estimated from the regression models about the characteristics of CLSM, before performing experimental tests.

With the rapid growth of Chinese economy, environmental issues also became a serious problem that public and private sector have to take under consideration. For the sustainable growth of Chinese economy scholars and policy makers agree to the stronger regulation for protection of natural environment, but at the same time worry about its negative effect on economic growth. This paper primarily focus on the relationship between the factors that have the effect on green product purchasing intention and purchasing behavior. Purchasing intention was considered as mediating variable in our model and state-action orientation - as moderating variable. We set 8 hypotheses and tested with structural equation modeling. The result shows that governmental regulation and subsidy, social environment related with green product purchase, and consumer perception on the benefit of green product have positive relationship with purchasing intention, but environmental concern does not show relationship with it. We also proved that state-action orientation has moderating effect between purchasing intention and purchasing behavior. Purchasing intention with action orientation show positive and statistically significant effect on purchasing behavior. This result supports the hypothesis that the attitude of customers has the effect on ones purchasing behavior.

The purpose of this research examined the relationship between the level of news usage on Influenza A(H1N1) and media users' behavioral intention toward health protection. Specifically, the study investigated causal relationships among exposure of media information on Influenza A(H1N1) as an independent variable, psychological protection motivation factors such as perceived severity, vulnerability, response efficacy, & self-efficacy as mediated variables and behavioral intention on personal and public health protection as dependent variables using structure equation model analysis. Self-reported questionnaires were administrated to 460 college students. The result indicated the followings. First, the level of news usage on Influenza A(H1N1) was not statistically significant on influencing behavioral intention toward personal and public health protection. Second, perceived severity, vulnerability, and self-efficacy were significant variables on behavioral intention toward personal health protection whereas perceived vulnerability and response efficacy were significant on public health protection. The function among factors in protection motivation theory is dependent upon whom protected from illness.

In this study, parallel work-learning training, which was started in 2013 as a pre-employment promotion policy, is an important factor that determines the success or failure of training. As a time when various institutional supplementation is needed to encourage company participation, this study is to identify the factors of participation of companies participating in work-learning parallel. To this end, a questionnaire survey was conducted of companies participating in parallel work-learning in Chungnam, and the results were analyzed using the structural equation model. As a result of the study, the reason for the company's participation in parallel work-learning was firstly, 84% of government subsidy received education and training expenses. Second, 66% of workers were able to pay less than regular workers, and thirdly, it was easy to hire new employees in the field. 26%, 17% of them were invited by acquaintances for no particular reason. Therefore, the study suggests that participation in the work-learning parallel training contributes to the management costs, management of employee turnover, and human resource development. In future research, it is necessary to subdivide tests and estimates by conducting studies on regions, occupations, gender, wages, and years of service in Korea.

Physical resources are central to coping with economic hardships for people in low-income, yet life experiences such as resource loss and gain and their relationships with a sense of well-being received scarce attention. Thus this study investigated levels of loss and gain of physical resources, economic stability and well-being of 254 adults who participated in welfare-to-work programs; correlations and paths among these variables; and direct and indirect effects of economic stability by structural equation modeling. Major results were: first, the levels of resource loss and gain were below a moderate level and the level of gain was significantly higher than the loss level. Second, in the relationships with both economic stability and well-being, resource loss showed negative correlations, while resource gain showed significantly positive correlations. Third, the negative direct effect of resource loss either on the economic stability or on the well-being respectively was significant and the indirect effect on well-being through economic stability was also significant. Finally, the direct effect of resource gain on either economic stability or well-being was significant; and the indirect effect of resource gain on well-being was also significant. Thus in both models for resource loss and gain, the indirect effect of economic stability was significant, which supports partial mediation model. Based on these results, implications for social work practice and research were examined, particularly for enabling social work practice to utilize information regarding resource loss and gain, economic stability, and a sense of well-being that were embedded in the community life of people in low-income.

The main purpose of this study is to investigate the effects of operational practices of contract foodservice management company on relationship quality and recontract intention. To verify research model, 126 data were collected from client companies of E contract foodservice management company and analyzed using structural equation modeling and multiple regression. The results of this study can be summarized as follows. First, direct factors such as operational costs, menu management, and service management had significant influences on food service quality. On the other hand, indirect factors such as operational supportability, brand image, and capacity of sales management were not important to food service quality. Second, indirect operational practices had significant effects on trust. That is, when operational supportability was increased, brand image was enhanced, and capacity of sales management was strengthened, client company's trust on contract foodservice company was increased. Among them, brand image showed the highest effect. Also, direct practices such as operational costs, menu management, and sanitary/facilities management significantly influenced on trust. Third, food service quality significantly affected trust. Finally, only trust had significant effect on recontract intention but food service quality did not. This means that food service quality alone is not enough to earn recontract intention. Relationship marketing efforts to form trust should be made between contract foodservice company and client company.

The purpose of this research is to confirm how the determinant factors for shopping mall selection (proximity, parking facility, benefits, mutual interaction effects, physical environment, surroundings) affect attractiveness (image and appraisal) of the traditional markets and revisit intention and suggest strategic methods for revitalization of the traditional markets. Results of this research are drawn from a survey of customers who visit any of the twenty-two traditional markets in the Seoul area at least twice a week. Moreover, the theory is verified through the structural equation model analysis using the SPSS win 18.0 and AMOS 18 version statistics package. From the determinant factors of visiting traditional markets, parking facility, physical environment, and the surroundings were significant in image attractiveness; benefits, mutual interaction effects, and physical environment showed significant effects on appraisal attractiveness. Additionally, image attractiveness was not significantly influential in retention proneness while appraisal attractiveness was a key factor in deciding whether or not to revisit. Therefore, improvement in image is important but appraisal aspects like product reliability that customers can personally assess, are more essential for revitalization of traditional markets.
