In the knowledge-based society, utilization of women's resources has significant implications as the key to success of national competitiveness. The space and conditions for women to show their abilities in all areas should be provided. Policies on women's resources, which aim to achieve gender equality, should not be limited to the area of social welfare as usual, but should be treated in-depth with relation to political, economic, social, and cultural areas. Local women policies do not reflect the distinct characteristics of the local areas and realities of women, furthermore, even the concept of women policies is not delivered to local women. In this study, directions to shift local women policies from the marginalization to the mainstream of policy are discussed focusing on utilization of women's resources.

From the cost-effective point of view, it is very important to design a current with the highest utilization factor of current capacity of power devices. This can be accomplished by a current controller without overshoot irrespective of the varying bounds of control voltage in PWM converters and the dead time due to the time delay. This paper suggests a novel decoupled controller with Smith-Predictor which has the fast control response without overshoot and steady stats error and also deal with the design method of the controller for PWM converters. The extensive digital simulations done by SIMULINK/MATLAB show that the suggested controller guarantees the full utilization of current capacity of power devices and the decoupled current control behavior.
