Creating and maintaining a learning organization is a competitive advantage, which would be the result of valuable outcomes such as innovation, efficiency and the better convergence with environment. In addition, learning is the best way to preserve life, survival and growth of organizations in future. In this regard, this study examined the relationship between trust and learning organizations. This study had one main hypothesis and five sub-hypotheses. Research method was descriptive, and t-test and correlation tests were used to determine the relationships between variables. The statistical populations of this study were employees and faculty members of Payam Noor University in east Azerbaijan province, Iran. The results of this study show that there was a meaningful and positive relationship between trust in organization and learning organizations. Therefore, it is recommended that organizations dismantle the barriers of trust, be promoted the trust-builder interactive relationships; be improved and be promoted the mechanisms of interpersonal communications.

Every day, we deal with the information, which are under uncertainty and managing this type of information with classical database systems brings a disadvantageous loss of data semantics along. Therefore, advanced database modeling techniques are necessary. Entrance of object orienting concept in databases helps relational database gradually use object oriented database in various fields. With the advances in this field, simple objects alone are not able to include complex data types and complex objects are necessary. On the other hand, for solving the problem of fuzzy data, several methods have been presented. One of these methods for modeling databases is an approach, which couples object-oriented database modeling with fuzzy logic. In this research, we observe the compilation of XML and fuzzy to represent a suitable approach for queries in object-oriented databases. In this paper, by combining sql and fuzzy XML tags, a language and independent database for storing and retrieving queries is prepared. We study database queries in two forms of simple and complex. In the form of complex, we use conjunctive queries.

Energy supply security is one of the strategic issues of all states. Beside the energy supply management, the section that has received less attention is energy demand management. According to importance of residential and commercial sectors in energy consumption, in the present study energy demand of these sectors is estimated using linear and exponential functions and the coefficients are obtained from PSO algorithms. 72 different scenarios with various inputs are investigated. Data from the years 1968 to 2011 are used to develop the models and select the suitable scenario. Results show that an exponential model developed based on particle swarm optimization algorithm has had the best performance. Based on the best scenario the energy demand of residential and commercial sectors is estimated 1718 Mega barrel of crude oil equivalent up to the year 2032.
