This logic gate is used to increase processing speed and data transmission [1]. All-optical logic gates based on fiber have difficulty in chip scale integration, and optical logic gates based on waveguide interferometers have a complicated structural arrangement. Moreover, the performance of logic gates with a micro resonator structure and semiconductor optical amplifiers are limited to moment emission noise [2]. Photonic crystals (PC) are a new class of dielectric materials proposed by Yablonovitch and John which can be used in making photonic integration devices with dimensions equal to a wavelength [3]. Presence of photonic crystals (PC) in the design of all-optical logic gates leads to a high potential in compression and reduction of the size of ultra-fast switching devices as well as reduction in power consumption [4].Photonic crystals transmit or reflect light ...

Therefore, the purpose of this study was to examine the role of the use of information and communication technology (ICT) skills on the share of productivity components of human resources for the improvement of the functional system of management of the department of power distribution centers in districts of Guilan province. : This study was a descriptive-correlational research. The statistical population was included all employees in the power distribution centers of Guilan province. The instrument of this study was included the Human Resources Questionnaire based on the ACHIEVE model (Hersey and Goldsmith) and the questionnaire of Information and communication technology for development (ICT4D). The collected data were classified by descriptive statistical methods and were analyzed by the Kolmogorov-Smirnov test and Pearson and Spearman Correlation Coefficients. The SPSS software (version 23) was used for data analysis (α≤0.05). Results: 75.22% of subjects were men and 24.78 of them were women. The correlation coefficient was 0.58 between ICT and productivity, 0.59 between administrative services and productivity, 0.48 between electronic services and organizational productivity, 0.49 between communication networks and productivity and 0.37 between the use of system hardware and productivity. It is suggested that the traditional methods of executive work should be avoided due to the continuous productivity and there will be closer relationship with productivity if the specialized training increases in service and executive organizations.
