This study focused on whether employees' perceived leader's creativity has a significant effect on employees' job satisfaction and innovative behavior. In addition, this study analyzed the mediating effect of positive psychological capital and creative self-efficacy in the relationship between perceived leader creativity and employee satisfaction with the job or innovation behavior, and analyzed the moderated mediating effect of team cohesion. This study conducted confirmatory factor analysis and path analysis for each factor using the measurement tool verification method using the SmartPLS 3.0 structural equation model, and empirically analyzed the research model. As a result, it was found that the creativity of employees' perceived leaders did not directly significantly affect employees' job satisfaction and innovation behavior. However, it was found that positive psychological capital significantly mediated the relationship between perceived leader creativity and job satisfaction or innovative behavior. In addition, positive psychological capital and creative self-efficacy have a complete double-mediation relationship between the employees' perceived leader's creativity and employees' innovative behavior. However, positive psychological capital and creative self-efficacy don't have a double-mediation relationship between the employee's perceived leader's creativity and employees' job satisfaction. Finally, Team cohesion was found to moderate the relationship between perceived leader creativity, positive psychological capital (or creative self-efficacy). However, the research model that the moderated mediating effect of team cohesion on the relationship between leader's creativity, the mediating variables(positive psychological capital and creative self-efficacy), and job satisfaction (or innovative behavior) was significant only for groups with high team cohesiveness. This study examined the needs of the times for the importance of creativity of perceived leaders and analyzed the relationship between factors influencing job satisfaction and innovation behavior of organizational members. The study is meaningful in that it suggested a plan to establish a specific organizational strategy to enhance positive psychological capital and creative self-efficacy.

The purpose of this study was to investigate the relationship between job stress, coworker support, emotional stability and burnout, and to examine the mediating effect of coworker support and emotional stability. A total of 212 noncommissioned officers were interviewed and correlation and mediating effect analysis were applied to the resulting data. As a result, the job stress showed a positive correlation with coworker support, emotional stability and negative correlation with burnout, and coworker support and emotional stability showed a negative correlation with burnout. In addition, coworker support and emotional stability were partially mediated by job stress and burnout. However, in order to examine the relationship between these two, the double mediation between job stress and burnout showed that the emotional stability of job stress was partially mediated directly by burnout, and that coworker support was mediated by burnout only through emotional stability. Based on these results, the implications and limitations of this study were discussed.

Photoheterotrophic evolution of molecular hydrogen by Rhodobacter sphaeroides is mediated by nitrogenase that is regulated transcriptionally and post-translationally by ammonium ion. Two PII-like proteins, GlnB and GlnK, play key roles in mediating inhibition and repression of nitrogenase in the presence of ammonium ion. glnB and glnK of R. sphaeroides were interrupted to abolish the ammonium ion effect controlling nitrogenase. Ammonium ion effect was still observed in mutant having an interruption in either glnB or glnK. However, the nitrogenase activity of glnB-glnK double mutant is not affected by ammonium ion. $H_2$ evolution was improved by increasing gene dosages of nitrogenase-coding genes, nifHDK in trans in glnB-glnK double mutant.

This study aims to analyze the causality of placeness cognition which includes the place satisfaction, place attachment, place function, and behavioral intention of those who visit Suseong amusement park. A questionnaire survey was administered to 255 individuals who visited in Suseong amusement park. To conduct the analysis, six hypotheses were formulated and tested. While two hypotheses were statistically rejected, four hypotheses were accepted. First, place satisfaction was found to have a positive effect on place function (β=.577, p<0.001). Second, place attachment had a positive effect on behavioral intention (β=.450, p<0.001). Third, place function had a positive effect on behavioral intention (β=.247, p<0.05). Fourth, place function was found to have a positive effect on place attachment (β=.637, p<0.001). Unlike most existing research which has indicated that place satisfaction has a direct effect on behavioral intention this study suggests a that double mediating effect through place function and place attachment between place satisfaction and behavioral intention.
