Realism not only has introduced way of thinking but also has discussed a different way of expression in mid-nineteenth century in west and despite its existence has experienced new forms during its stages of development and metamorphosis. Symbolic realism has been discussed as a realistic technique in art and literature style within this through this method, realism and symbolism make contradictory link where although symbolic relationships are formed but signifier, arbitrary signified as well as secondary all have realistic approach in this link which mean in context realistic channel as well as receiver's experimental mind connection with that, although culture, society, policy, history, myths and legends are also represented but they aren&rsquot determinant of meaning and only can be crystallized in second half discovery of signifier as receiver&rsquos mental reserves and of course this is the result and related to discussed realistic patterns in work. This research is sought to investigate symbolic realism which is a kind of realism that is used as technique in a work and can be one of its style indicators and considered as main style in case of its extent of function in work. Besides structural investigation of "symbolic realism", history, approach as well as introducing its artists and writers are investigated in this research and has explained rout map for further researches in this field not only in literature field but also in architecture, painting as well as religious issues.

The electronic industry suffers a rapid changing and highly rival environment. Thus, firms have an essential need to strive for acquiring the competitive advantage. Strategy Organizational Agility (SOA) is a tool which enables to assist firms to attain the competitive advantage. Therefore, this study benchmarks the core competencies from a case study within the supply chain network and establishes a set of attributes for augmenting SOA. A novel multi-criteria decision-making structure is proposed to deal with the complex interrelationships among the aspects and attributes. Radial basis function (RBF) neural network can use linear learning algorithm to complete the work formerly handled by nonlinear learning algorithm, and maintain the high precision of the nonlinear algorithm. However, the results of RBF would be slightly unsatisfactory when dealing with small sample which has higher feature dimension and fewer numbers. Higher feature dimension will influence the design of neural network, and fewer numbers of samples will cause network training incomplete or over-fitted, both of which restrict the recognition precision of the neural network. The competence and accountability indicators can the continuously increasing level of agility to be effective. According to the analysis chart production and product design performance indicators alone cannot level a considerable amount of agility to change. But reducing the level of the index level of agility is reduced. Flexibility indices speed and agility level changes can also affect the organization. But with increased levels of these two indicators increased agility rate change indicators will be more flexibility. The results showed that customer knowledge management impact on organizational agility and organizational effectiveness and customer knowledge management through organizational agility has significant positive impact on organizational effectiveness. Finally, some practical suggestions, future research suggestions and research limitations are presented.

This paper sought to evaluate cultivation social and economic of Atriplex lentifomis in Golestan rangelands (case study: Chapar Quymeh and Baharmeydan). the present research is conducted in a survey, descriptive and explanatory manner (hypothesis testing) in which field and library researches were used. research population is a number of ranchers in plan region of Chapar Quymeh (93 people) and a number of ranchers in plan region of Baharmeydan (37 people), research sample size for Chapar Quymeh and Baharmeydan was estimated to be 75 and 37 stakeholders according to Krejcie and Morgan formula. Sampling was carried out in systematic random way and tools used in research include researcher made 25-item inventory with Likert scale. The results of factor analysis test and ranking social and economic indices showed that factors affecting Atriplex cultivation in Baharmeydan area are as follow: production, income and capital, entrepreneurship, social welfare, recreational value, hygiene, sense of belonging to place, institution and education respectively. As for Chapar Quymeh this prioritization is: production, income and capital, entrepreneurship, institutional, social welfare, sense of belonging to place, recreational value, hygiene and education. Using one-sample T test, it was found that the outcomes of social and economic indices affected by bush planting are positive in study areas
