  • Currently, companies are focusing on how they make their members have change-oriented organizational citizen behavior in the era of fierce competition due to the 4th industrial revolution. Therefore, this study verified how the flexible culture of adhocracy-clan plays a role in positive psychological capital and change-oriented organizational citizen behavior. A survey was conducted for employees in companies located in Daejeon-si, Sejong-si, Chungcheongnam-do, and Chungcheongbuk-do, and 394 valid questionnaires were used for analysis. The concrete analysis results are obtained from the study as follows. First, among the flexible cultures of adhocracy-clan, the innovation culture was found to have a significant effect on change-oriented organizational citizenship behavior while relationship culture was found to not directly affect change-oriented organizational citizenship behavior. Second, the flexible cultures of adhocracy-clan, the innovation culture was found to have a significant effect on the positive psychological capital. Third, the positive psychological capital was found to have a significant effect on the change-oriented organizational citizenship behavior. Fourth, the positive psychological capital was found to play a mediating role in the relation between the recognition of flexible cultures of adhocracy-clan and the change-oriented organizational citizenship behavior. Therefore, it can be said to find out the fact that the change-oriented organizational citizen behavior can appear under the fierce competition as nowadays only when the organization should establish the organization culture of innovation-relation or the members are in the positive psychological state. We expect that the future study on the type of subculture and new organizational citizen behavior will be made in the manner of classifying the unit of organizational culture into a headquarter or team for measurement.

  • $MWCNT-TiO_2$ nano composites and $Ag-MWCNT-TiO_2$ nano composites were prepared from Multi-Walled Carbon NanoTube (MWCNT), titanium (IV) butoxide (TNB) solution and silver nitrate ($AgNO_3$) by the sol-gel method. The dispersion and structure of Ag in the synthesized composites was observed by Scanning Electron Microscopy (SEM) and Field Emission Transmission Electron Microscopy (FE-TEM). X-Ray Diffraction (XRD) patterns of the composites showed that the composites contained an anatase phase. The Energy Dispersive X-ray spectroscopy (EDX) showed the presence of C, O, Ti and Ag peaks. The $TiO_2$ particles were distributed uniformly in the MWCNT network, and Ag particles were virtually fixed on the surface of the tubes. Also decomposition of the methylene blue was investigated according to UV radiation times for study photocatalytic activity. $Ag-MWCNT-TiO_2$ nano composites show high photodegradation than $MWCNT-TiO_2$ nano composites. The results indicate that the high conductivity of Ag improved the photoactivity of the $MWCNT-TiO_2$ composite.

  • The purpose of this study was to investigate the influences of 5 intrinsic and 5 extrinsic factors on technology teachers' job satisfaction and commitment. The collected data from 108 technology teachers in Gwangju city and Jeolla Nam-do, were analyzed and tested at p<.05 or more by using Multiple Regression through SPSS program. The levels of the teachers' job satisfaction and commitment were respectively M=3.91 and M=3.69 at Likert scale. Among 5 intrinsic and 5 extrinsic factors, other factors except for two factors-work environment and salary were, even if a little, satisfied to the teachers. They were more satisfied with the intrinsic factors than the extrinsic. $R^2$=.515 was found between teachers' job satisfaction and the combination of 10 factors-achievement, work itself, responsibility, opportunity for growth, recognition, job safety, work environment, salary, supervision skill, human relation. $R^2$=.616 was between teachers' commitment with the combination of the factors. The combinations were respectively accountable for 51.5% of the job satisfaction change and for 61.6% of the commitment change. The relative importances of the factors were salary first, achievement second and others not for the job satisfaction, and achievement first, opportunity for growth second and others not for the commitment. The generalization of the above results is limited to improving technology teachers' job satisfaction and commitment at the secondary level in Gwangju city and Jeolla Nam-do.
