This study investigated the effect of digital agriculturalization factors on business performance with the use of financial support as a moderating variable for agricultural firm workers. The factors of digital agriculture were divided into digital technology innovation orientation, administration innovation orientation, healthiness of ecosystem and entrepreneurship orientation, and business performance was set as a dependent variable. 212 questionnaires collected from workers in agricultural businesses located across the country were used for empirical analysis. Analysis results using SPSS v22.0 and Process macro v3.4 are as follows: First, digital technology innovation orientation, administration innovation orientation, and entrepreneurship orientation have a significant effect on business performance, and the effect of ecosystem health on business performance is appeared to be insignificant. Second, the use of financial support was found to significantly moderating the relationship between digital technology innovation orientation and business performance, entrepreneurship orientation and business performance. On the other hand, it was found that the relationship between operational innovation orientation, business performance, and healthiness of ecosystem and business performance were not significantly moderated In addition, as a follow-up study, a study on the mediation model formed by the discovery of mediators and a study for a moderated mediation analysis through a conditional process model with additional mediators are required.

The purpose of this paper is to analyze the effect of government R&D subsidies on business performance of SMEs in the field of Land, Infrastructure, and Transport. To this end, based on domestic and foreign literature, the performance derived through R&D was classified as primary and secondary parameters, and the commercialization program operated by the government was set as a moderating variable. Regression analysis, double mediation analysis, and moderated mediation effect analysis were used to confirm the effect of government R&D subsidy on project performance and process. As a result of this study, it was confirmed that government R&D subsidies have a significant effect on corporate management performance, and it was confirmed that the primary performance such as papers and patents and the secondary performance such as prototypes and legislative revisions have a double mediating. In addition, when the commercialization program was applied to the first and second parameters, it was confirmed that it played a moderated mediating effect. The results of this study are expected to be used when establishing government R&D support plans to expand business performance and economic effects in the future.

The purpose of this study is to objectively quantify the degree of social exclusion of the disabled and verify the impact of the derived degree of social exclusion on the quality of life of the disabled. And the purpose is to verify whether job satisfaction moderates the impact of social exclusion and quality of life of disabled people. The subjects of the study were 1,280 people extracted through a panel survey on employment of the disabled. The independent variables of social exclusion are economic difficulties, employment status, mental health, and social activities. The dependent variable was quality of life, and the control variable was job satisfaction. The research results are as follows. First, the sub-factors of social exclusion that affect quality of life were economic difficulties, mental health, participation in social activities, and employment status. Second, job satisfaction showed a moderating effect in the relationship between social exclusion and quality of life. And the sub-factors of social exclusion that have a moderating effect on quality of life were identified as economic difficulties, employment status, and social activities. In follow-up research, it will be necessary to investigate employment programs for the disabled in developed countries and analyze the implementation background, implementation details, achievements, and limitations, thereby contributing to the establishment of employment policies for the disabled. It is hoped that through this research, the vicious cycle of social exclusion and discrimination of the disabled will be improved and an opportunity will be provided to improve the quality of life through the economic activities of the disabled.

This study is based on the previous research which proved that "seeking convenience", "seeking low-cost" and "pleasures of shopping" are the major shopping motivation of online shopping. Research is conducted by using the trust as mediator, purchase intention as dependent variable. Also, differences between Chinese and Vietnamese consumers are applied in analysis of the model. The results were as follows: First, "seeking low-cost" and "pleasures of shopping" have positive effects on trust. Second, all shopping motivation have positive effect on purchase intention. Third, the trust has positive effect on purchase intention. Fourth, consumers' shopping motivation have significant difference in trust and purchase intention according to Chinese and Vietnamese consumers. The results of this study presented the strategic implications for operators at online shopping area.

We prepared spherical silica particles by controlling various conditions of emulsion-gel procedure using a lab-scale membrane emulsification system equipped with SPG (Shirasu porous glass) membrane having pore size of 2.6 ${\mu}m$. We determined the effects of process parameters of membrane emulsification (dispersed phase pressure, stabilizer and emulsifier concentration in continuous phase, $H_2O$/TEOS ratio, ratio of dispersed phase to continuous phase) on the mean size and size distribution of silica particles. The increase of the dispersed phase pressure and ratio of dispersed phase to continuous phase led to the increase in the mean size of silica particles. On the contrary, the increase in stabilizer and emulsifier concentration and $H_2O$/TEOS ratio caused the reduction of the mean size of particles. Through controlling these parameters, monodisperse spherical silica particles with about 3 ${\mu}m$ of the mean size were finally prepared.

The purpose of this study is to use meta-analysis as a research method to investigate the correlation between early child teachers' teaching efficacy and their job satisfaction, and thereby look into the effect size of the two variables and their sub-variables. To achieve the purpose, this researcher chose a total of 37 theses for analysis and collected 289 data for analyzing the effect size. Based on the data, CMA(Comprehensive Meta Analysis) 2.0 was applied. According to the analysis, the correlation between early childhood teachers' teaching efficacy and their job satisfaction was higher than the medium effect size on the basis of Cohen(1992) research. In the sub-variables of teaching efficacy, the correlation of personal teaching efficacy with job satisfaction showed higher effect size than that of general teaching efficacy. In the sub-variables of job satisfaction, the correlation between the belief in job and teaching efficacy showed the highest effect size. In terms of thesis type as a moderating variable, Ph.D dissertations showed higher effect size than journals or M.A. theses. As the result of the meta-analysis on publishing year and the number of samples, there was no statistical significance. On the basis of the analysis results, discussions and limitations of this study were suggested.

The purpose of this study was to identify the factors related to awareness, treatment, and control of hypertension in Korea using data from the 4th KNHANES. The analytical technique employed multivariate logistic regression analysis and the major findings of this research are as follows. First, awareness of hypertension was positively associated with age, occupation, self-rated health, Body Mass Index, and health examination since 2 years ago, in both males and females. Second, treatment of hypertension was positively associated with age, self-rated health, Body Mass Index, and health examination since 2 years ago, in both males and females. Third, control of hypertension was positively associated with age, self-rated health, Body Mass Index, and health examination since 2 years ago, in both males and females. Finally, the results of analysis suggest that the government should especially focus on the vulnerable group and continue to strengthen effective efforts for improving awareness, treatment, and control of hypertension.
