This study inquires into employee's intent to leave in South Korean dental clinics. A systematic research was undertaken on theories of leadership types, job satisfaction, organizational commitment and empowerment, and then interaction between these variables was verified based on quantitative data by using Structural Equation Model (SEM). The findings suggest that making improvements of empowerment, job satisfaction, and organizational commitment demand individualized consideration and charisma, the components of transformational leadership. As a way to reduce turnover intention, the role of job satisfaction and organizational commitment was more influential than that of empowerment. Also, a combination of charisma of transformational leadership and contingent reward of transactional leadership turned out to be the ideal leadership type to reduce turnover intention. Lastly, the harmony of individual goal with that of organization, apparent documentation of reward system, and stress control were recommended as practical solutions to improve organizational profitability and effectiveness and to reduce turnover rate in dental clinics.

This study examined the effects of paternal participation in child care and social support on planning for a second childbirth, focusing on the mediating effect of the mother's parenting stress. The 887 subjects studied in this paper were mothers who have a first child, and were selected from a sample of the 2nd Panel Study of Korean Children(PSKC) by the Korea Institute of Child Care and Education(KICCE), conducted in 2009. Data was analyzed using a Structural Equation Model(SEM) to identify a structure and relationships among factors. The significance of indirect effects to test the mediating effect of maternal parenting stress was identified via bootstrapping. Results indicated that maternal parenting stress partially mediated the relationship between the father's participation in child care and planning for a second childbirth, and absolutely mediated the relationship between social support and planning for a second childbirth. The findings reveal the importance of reducing parenting stress, given its substantial impact on planning for a second childbirth.

Purpose This study investigates the effects of trust and distrust on intention to purchase in open market, based on the idea that trust and distrust can co-exist. Specifically, this study approached the effects of trust and distrust of the open market on the intention to purchase from a two-dimensional perspective, and examined trustworthiness as the antecedents of trust and distrust. Design/Methodology/Approach In this study, we conducted a questionnaire survey on consumers who have actually purchased a product from open markets in Korea for two months. As a result, 141 users are chosen for the sample. We apply PLS (Partial Least Squares) structural equation modeling (SEM) to verify our theoretical model using the software application SmartPLS 3.0. Findings First, trust in open market positively affects intention to purchase, whereas distrust in open market negatively affects intention to purchase. Second, the three antecedents of trust (i.e. three factors constituting trustworthiness such as ability, benevolence and integrity) affect trust in open market. Third, integrity negatively affects distrust in open market. Since integrity plays an important role in building both trust and distrust in open market, the operators of open market should pay attention to managing their integrity.

Purpose: The purpose of the study was to identify the mediating effect of organizational citizenship behavior between job embeddedness and turnover intention in hospital nurses. Methods: Data were collected from 241 nurses in 3 tertiary hospitals and 2 secondary hospitals in Daegu and analyzed using descriptive statistics, Pearson correlations and structural equation model (SEM) with the PASW 18.0 and AMOS 18.0 program. Results: There were negative relationships between job embeddedness and turnover intention (r=-.53, p<.01), and organizational citizenship behavior and turnover intention (r=-.39, p<.01) but a positive relationship between job embeddedness and organizational citizenship behavior (r=.39, p<.01). There was a partial mediating effect of organizational citizenship behavior between job embeddedness and turnover intention (${\chi}^2=91.02$, p<.001). Conclusion: The results of this study indicate that organizational citizenship behavior has a mediating effect on the relationship between job embeddedness and turnover intention in hospital nurses, suggesting that enhancing organizational citizenship behavior is required. in order to promote job embeddedness and reduce turnover intention.

Objective: The purpose of this study was to examine the effect of adolescents' callousness on reactive and proactive aggression through moral disengagement. Methods: The participants were 315 freshmen and sophomore high school student in Korea. The data were analyzed with Structural Equation Modeling(SEM). Results: First, adolescents' callousness did not show a significant influence on reactive aggression directly or indirectly through moral disengagement. Second, adolescents' callousness had a significant influence on proactive aggression directly and indirectly through moral disengagement. That is, adolescents' high level of callousness not only predicts a higher level of proactive aggression directly, but also influences moral disengagement which may result in a high level of proactive aggression. In addition, the gender difference in this model was confirmed. Conclusion/Implications: The results of this study indicated that adolescents' callousness could have different influences on aggression through moral disengagement by the types of aggression and gender. The results suggest that it is necessary to approach the emotional and cognitive process of adolescent aggression differently, depending on the type of aggression and gender.

The purpose of this research is to study the influence over confidence and Word-Of-Mouth (WOM) effect in the acceptance process of WOM by information characteristics(consensus, vividness, and message neutrality) of individual cosmetic blog, reflecting that it is widely spreading over the public. Online survey for the consumers using such blogs was performed to collect data(N=200), and credibility analysis through Cronbach-${\alpha}$ and Structural Equation Model(SEM) analysis using AMOS 18.0 were performed. The analysis results are as follows; First, vivid information and neutral message increase WOM effect through the improvement of consumers' credibility whereas information consensus doesn't positively influence over credibility. Second, the examination of a moderating effect by type of cosmetics demonstrated that the consumers of basic cosmetics have most confidence in vivid information, and those of color cosmetics do more confidence in neutral message. Therefore, there is a difference in the credibility factor of online WOM depending on the type of cosmetics consumption so that differentiated information provision strategies for cosmetics groups should be established based on it.

This paper presents responses of the free end of a cantilever micro beam under the effect of an impact force based on the modified couple stress theory. The beam is excited by a transverse triangular force impulse modulated by a harmonic motion. The Kelvin-Voigt model for the material of the beam is used. The considered problem is investigated within the Bernoulli-Euler beam theory by using energy based finite element method. The system of equations of motion is derived by using Lagrange's equations. The obtained system of linear differential equations is reduced to a linear algebraic equation system and solved in the time domain by using Newmark average acceleration method. In the study, the difference of the modified couple stress theory and the classical beam theory is investigated for the wave propagation. A few of the obtained results are compared with the previously published results. The influences of the material length scale parameter on the wave propagation are investigated in detail. It is clearly seen from the results that the classical beam theory based on the modified couple stress theory must be used instead of the classical theory for small values of beam height.

For the first time, nonlocal damped vibration and buckling analyses of arbitrary tapered bidirectional functionally graded solid circular nano-plate (BDFGSCNP) are presented by employing modified spectral Ritz method. The energy method based on Love-Kirchhoff plate theory assumptions is applied to derive neutral equilibrium equation. The Eringen's nonlocal continuum theory is taken into account to capture small-scale effects. The characteristic equations and corresponding first mode shapes are calculated by using a novel modified basis in spectral Ritz method. The modified basis is in terms of orthogonal shifted Chebyshev polynomials of the first kind to avoid employing adhesive functions in the spectral Ritz method. The fast convergence and compatibility with various conditions are advantages of the modified spectral Ritz method. A more accurate multivariable function is used to model two-directional variations of elasticity modulus and mass density. The effects of nanoscale, in-plane pre-load, distributed dashpot, arbitrary tapering, pinned and clamped boundary conditions on natural frequencies and buckling loads are investigated. Observing an excellent agreement between results of current work and outcomes of previously published works in literature, indicates the results' accuracy in current work.
