Stress level of parents of hearing impaired children

The study attempted to determine the effects upon the family system of having a child diagnosed with deafness or hearing impairment. The specific variables are the rating of father stress, rating of mother stress. If any difference exist between maternal and paternal level of stress variables. The intent of this study is to better define the stress of parents due to disability of their children. The researcher used the translated version of standardized questionnaire on resources and stress short form (QRS-F) was used developed by William friedrich (1989). It constituted of 35 items. The sample consisted of 350 parents comprises(175 fathers and 175 mothers) of hearing impaired children who were studying in 1-5 grade at government special education schools and centers in Gujranwala district. Key words: stress, hearing impaired, deafness, paternal stress, maternal   stres

Ultra-wideband fractal ring antenna for biomedical applications

Abstract In this paper, an efficient, coplanar waveguide (CPW)-fed printed circular ring fractal ultra-wideband (UWB) antenna is presented for biomedical applications. In UWB technology, short-range wireless communication is possible with low transceiving power, a characteristic that is particularly advantageous in the context of microwave and millimeter-wave (mmWave) medical imaging. In the proposed antenna configuration, the UWB response is achieved by introducing wedged slots in the radiating patch, designed on a low-loss substrate. A CPW partial ground plane is truncated from the edges to optimize the antenna impedance. Experimental results indicate the antenna’s robust performance across the frequency range of 3.2–20 GHz. The well-matched measured and simulated results confirm our contribution’s employability. Furthermore, a time-domain study offers valuable insights into how the antenna responds to transient signals, highlighting its responsiveness and adaptability to biomedical applications
