This study provides an approach to perform the double mediation analysis in structural equation models using the R. For this purpose, the study reviews a variety of techniques for mediation analysis, selects the bootstrapping technique as the most suitable way for performing the double mediation analysis and develops an approach for the double mediation analysis in structural equating models with the bootstrapping using the plspm which is the R package for the performing PLS path analysis. This study will be useful for the studies including the double mediation analysis in structural equation modeling, which is not supported by most of SEM packages, also will provide the knowledge base for in-depth analysis through suggesting the new mediation analysis technique using R for the researchers.

One of the main objectives of this paper is to identify the mediating effects of both social and intellectual capitals in the relations between entrepreneurship and innovation performance in Small and Medium Businesses. Based on the previous literatures on their relationships, we set our research model and test our hypotheses through a questionnaire survey. The main results of our analyses are as followings: first, entrepreneurship has a significant effect on innovation performance; second, social capital has a significant mediating effect between entrepreneurship and innovation performance; and finally, there exists a significant mediating effect between intellectual capital and entrepreneurship. One of the main policy implications of this study would be that the level of both social and intellectual capitals, coupled with entrepreneurship, should be reinforced in order to improve innovation performance.

This study analyzed the multi-mediating effects of information security, personal information infringement, personal experience, and information security intention in the relationship between personal information protection and information security attitude. For this purpose, a survey was conducted on 221 students from G University. First, information security, personal information infringement, and information security awareness had a simple mediating effect. Second, information security, personal information infringement, personal experience, and information security consciousness had parallel multi- mediation effects. Third, personal information infringement and information security awareness had a simple mediating effect in the parallel multiple mediation state. Fourth, information security had a simple mediating effect, but it was found that there was no simple mediating effect in the parallel multiple mediation state. This study is meaningful in that it empirically compared the simple and multi-mediation effects.

The purpose of this study was to propose a proper method for the multilevel mediation analysis, for which the hierarchical method should be utilized, then MLM (multilevel modeling) approach as a hierarchical method has been popularly utilized until MSEM (multilevel structural equation modeling) approach was not proposed. This purpose was covered by three research questions about statistical methods, analytic procedure, and real example. First, MSEM statistical method was preferred to MLM method for its estimation accuracy and analytic flexibility. Second, the four-step procedures of model building, assumption examination, model comparison, and coefficient testing were proposed for the multilevel mediation analysis. Third, the real data of 2695 students of elementary and secondary schools and 89 teachers were analyzed in the multilevel directions of $2{\rightarrow}2{\rightarrow}1$ and $1{\rightarrow}1{\rightarrow}2$. Out of these directions of $2{\rightarrow}2{\rightarrow}1$, and $1{\rightarrow}1{\rightarrow}2$ model, only the coefficient of $2{\rightarrow}2{\rightarrow}1$ model was significant at the 95% CI. Mplus programs used for the real example are attached on the Appendix. Based on the results, significance and limitations of this study, were discussed in detail.

본 연구는 확장된 합리적 행동이론(ETRA)을 이용하여 주식투자 시 자본시장심리지수를 기반으로 한 어플리케이션의 선택행동에 영향을 끼치는 요인들과 투자자의 휴리스틱과의 관계를 알아보는데 있다. 연구자는 개별 투자자의 휴리스틱이 선택행동에 영향을 미칠 것으로 추정하고 대표성 휴리스틱, 가용성 휴리스틱, 감정 휴리스틱을 측정하여 선택행동에 영향을 미치는 매개변수로 분석을 하였다. 연구모델의 경로계수 분석결과는 다음과 같다. 첫째, 독립변수인 투자기회확장 그리고 매개변수인 휴리스틱 중 대표성 휴리스틱이 행동의도에 영향을 미치는 것으로 나타났다. 둘째, 행동의도가 종속변수인 선택행동에 영향을 미치고 매개변수인 가용성 휴리스틱이 선택행동에 영향을 미치는 것으로 나타났다. 연구모형에서 대표성 휴리스틱에 영향을 주는 독립변수는 혁신적 성향, 투자기회확장, 사용비용, 그리고 인지된 효익이며 반면에 가용성 휴리스틱에 영향을 주는 독립변수는 혁신적 성향과 투자기회확장으로 밝혀졌다. 매개효과 검증결과에 의하면 서비스다양성은 선택행동에 영향을 미치는데 휴리스틱의 매개효과가 없고 직접효과만 있는 것으로 밝혀졌다. 반면에 투자기회확장은 선택행동에 미치는 직접효과는 통계적으로 유의하지 않고 매개변수 휴리스틱의 간접효과 값이 0.217이고 통계적으로 유의하여 매개효과가 있는 것으로 밝혀졌다. 휴리스틱의 매개효과를 개별적으로 확인한 결과 첫째, 대표성 휴리스틱은 매개효과를 통한 간접효과가 없는 것으로 확인되었다. 둘째, 가용성 휴리스틱은 매개효과의 크기가 0.1360이고 경로계수가 통계적으로 유의하게 나타나 매개효과를 통한 간접효과가 있다는 것을 확인하였다. 따라서 독립변수 투자기회확장은 시장 심리지수를 기반으로 한 어플리케이션에 대한 선택행동에 영향을 미치는데 직접적으로 영향을 미치지 않고 투자자의 가용성 휴리스틱이 매개가 되어 간접적으로 선택행동에 영향을 나타내는 것을 실증적으로 확인하였다.

This study is to analyze the relationship between Taeoom(workplace bullying) and organizational performance and to investigate the mediating effects of organizational silence between the relationship among nurses. In order to test the causal and mediating effects, this study employs the mediation analyses with regression. The sample is 273 from A university hospital in Seoul. Based on the results, Taeoom is basically, negatively associated with organizational performance. Acquiescence silence has played a full mediating role in the relationship between Taeoom and organizational performance. That is, Taeoom is not directly associated with organizational performance; however, it has a negative effect on organizational performance through acquiescence silence. Defensive silence plays a partial mediating role in the interdependence relationship. The implications of this study are that the negative effects of Taeoom would increase organizational silence and performance directly and indirectly; therefore, it is necessary to provide institutional prevention of Taeoom.

This study seeks to find a way to induce users to expand their direct participation in sports through the acceptance of digital technology. From July 1 to August 30, 2022, a survey was conducted targeting home training users who applied the Internet of Things (IoT). 129 people participated in the survey through non-face-to-face self-administration method. For data processing, frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, multiple regression analysis, and 3-step mediation regression analysis were conducted using IBM's SPSS 21.0 program. The results of the study are as follows. First, in the relationship between the home training PPM model and direct participation in sports, ease appeared to have a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. In the mooring factors, individual innovativeness showed a complete mediating effect. Second, in the relationship between home training PPM model and direct participation in sports, usefulness showed a mediating effect. In the factors of push, simple functionality showed a complete mediating effect, and inefficiency showed a partial mediating effect. Among pull factors, enjoyment and possibility of experience showed a complete mediating effect. Among the mooring factors, individual innovativeness showed a partial mediating effect. Through this research, it is expected that the sports industry will contribute to the expansion of consumption expenditure and economic growth through the expansion of digital technologies such as NFT, Metaverse, and virtual/augmented reality.

This study investigated the impact of social capital on married immigrant women's parenting, specifically focusing on the mediating effect of parenting participation. Using structural equation modeling, social capital within and outside of the family were examined in their relations to parenting efficacy, and the mediating effect of parenting participation was analysed. Study participants were 459 immigrant women from the Gyeonggi Education Welfare Panel(2011), who had children in 5th and 6th grades of elementary school. Findings suggested that social capital within and outside of the family had significant impact on parenting participation, which in turn affected parenting efficacy. Direct effects of social capital on parenting efficacy were not statistically significant, indicating a full mediation effect of parenting participation. Implications for social work practice and social policy for this population are discussed.
