In this study, the psychological structure was studied as a mediator variable in the relationship between organizational capital optimism and psychological capital was studied. This study is descriptive-survey based on the data collection method. In this study, 290 students of Farhangian University were studied as a statistical sample using simple random sampling. Data were collected through a questionnaire. the reliability of the instruments measured using Cronbach's alpha and combined reliability and validity of the instruments was determined using a convergent and divergent validity method. Structural equations and Smart PLS2 software were used to analyze the data. The findings showed that psychological capital and academic optimism respectively: Prognosis and consequence of psychological atmosphere are considered and scientific optimism with the resilience component has a negative and positive relationship with the components of self-efficacy, hope and optimism (P<0.05). Overall, results indicated that 44 percent of academic optimism changes are directly explained by the components of psychological capital and 45 percent of the scientific, indirect and optimistic changes through the psychological climate mediator variable. The research has provided important theoretical and empirical findings for future research on academic education and optimism, and also suggests that student perception of the psychological climate is a requirement for scientific optimism.

The research method is descriptive-correlation. The sample (According to the entry requirements for this study) consist of 210 Khuzestan Steel Company employees who selected by Stage random sampling (males=199; female=11).
The occupational commitment, psychological climate, NEO personality trait, General transformational leadership, Islamic work ethic,turnover intention, Burnout and self development behavior scales was used to collect research data. fitness of the proposed model was examined through structural equation modeling )SEM( by using amos-21 software package.also the bootstrap procedure was used for examine the indirect effects.
