Abstract: From the rational theory perspective, an organization is a means to achieve certain and established goals. Being rational is not only objective, but also incorporate ways to achieve the goal. In any organization, after the implementation of rational systems, its effectiveness on the organization’s output including staff performances must be explored. In this paper, we have investigated the effects of rational organization on performance of employees at district 4 of Tehran’s education administration, through the statistical software SPSS and Lisrel for structural equation of model. Results showed a positive and significant correlation between the effects of rationalization on the performance of staff of district 4 education administration.

Abstract: In Digital era, our life is bound with digital technology. In Information Technology, everything is available in digital form only. In the field of data communication, there is a need to send and receive data. But we don’t know the data will reach the destination successfully and securely. Security and privacy plays an important role in digital and data communication. In the field of secure data communication, cryptography is very important technique. Till now, we have seen many algorithms that are related to symmetric and asymmetric encryption and decryption. Most of the algorithms are related to text/data only. In this technique, there is a need to maintain one shared secret key or a pair of privatepublic keys. Why can’t we send encrypted data without using any key(s)? This proposed method tells us how to implement cryptography using mathematical method “Double-Reflecting Data Perturbation Method”.

Abstract: A field investigation was conducted during winter (rabi) season 2010-11 and 2011-12 in Vertisol to study the response of wheat yield, nutrient uptake, protein content and effect on soil properties to zinc application. The recommended doses of N, P and K were applied @ 120 N : 60 P2O5 : 40 K2O kg ha-1 in combination with Zn @ 0, 1.25, 2.50, 5.00, 10.00 and 20.00 kg ha-1 as zinc sulphate at the time of sowing in all the treatments. Pooled analysis of data revealed that yield, harvest index, nutrient (N, K and Zn) uptake and quality increased significantly with the application of recommended NPK+Zn @ 20.00 kg ha-1 by wheat as compare to NPK alone. In general, yield, harvest index, total nutrient uptake and quality increased up to highest level of Zn, except total P uptake. The maximum yield (grain - 4.66 and straw - 5.44 t ha-1 ), harvest index (46.07), total nutrient uptake (N - 123.19 kg ha-1 , K - 90.86 kg ha-1 and Zn - 327.74 g ha-1 ), total carbohydrate (70.37%) and gluten (12.37%) content was achieved by the application of 20.00 kg Zn ha-1 with recommended NPK as compare to control and other treatments, while the total P uptake was decline with increasing levels Zn. There is no appraisal change in soil pH, EC, organic carbon and CaCO3, but the status of DTPA-extractable Zn of soil was improved remarkably due to rational Zn fertilization combined with recommended NPK.
