As Korean society becomes more matured, more people consider trust valuable, as a social capital. Researchers introduced trust literatures focusing on public policy, sociology than business. In this paper, it is empirically analyzed how Organizational Justice, Shared Values, Organizational Trust, 3 dimensions of social capital explained by Nahapiet & Ghoshall, together with Job Satisfaction and Innovative Behavior, as a proxy of performance at the organizational level. The results of this study are as below. Firstly Organizational Justice, consisted of 4 sub-variables of Distributional Justice, Procedural Justice, Interpersonal Justice and Informational Justice, classified by Colquitt, affects Job Satisfaction positively. Secondly Shared Values, consisted of 2 sub-variables of CEO's Core Value and Organizational Culture, availing Competing Value Model of Cameron & Quinn, affect Job Satisfaction positively. Thirdly Job Satisfaction, consisted of 2 sub-variables of economical satisfaction and self-efficacy, affects Innovative Behavior positively. Lastly Organizational Trust has mediating effect on the relationship between Job Satisfaction and Innovative Behavior. However, while the direct effect of Job Satisfaction on Innovative Behavior shows 69%, the indirect effect of Organizational Trust on Innovative Behavior shows 31%, which may not be ignorable. Furthermore in case of smaller organization with less than 30 members, the indirect effect of Organizational Trust shows 64%, comparing to 36% of direct effect of Job Satisfaction. This study was able to confirm that organizations need to maintain Organizational Trust as much as they strive to increase Job Satisfaction through securing Organizational Justice and Shared Values in order to effectively increase Innovative Behavior. For small organizations with less than 30 members, they can never achieve Innovative Behavior without Organizational Trust. Conclusively it is acknowledged that Organizational Trust is the most important prior condition for innovation and long-term survival of SME ventures.

This paper describes a study on the permeability reduction of the riverbed ground during urban railway tunnel construction. The research is mainly concentrated on the study of the grouting or injection methods among permeability reduction methods which can be adapted in the riverbed ground. Firstly, the various grouting methods are theoretically reviewed and compared based on the previous research papers and case study results. It is also evaluated the grouting methods in view of a safe construction of the river crossing railway tunnel. Baced on the literature review and previous construction data, the design technology of grouting methods considering the long term hydro-geological behaviour in the riverbed, is suggested. Two injection methods namely, Natural Durable Stabilizer(N.D.S) and Space-Multi Injaction Grouting(S.M.I) methods, are introduced as new approach methods which can be adopted to modify the riverbed ground. In order to evaluate the ground that grouted and modified by the N.D.S and S.M.I method, the pilot test programmes including the field and laboratory permeability tests, are carried out in the river crossing tunnel construction sites. The results obtained from pilot test programme, are also reviewed. In conclusion, the grouting efficiency of the S.M.I method using the non-alcalimeter silica sol is better than that of NDS method using cement. In addition, it hopes that the research results are contributed to develop the grouting design technology.
