Mathematical analysis of Zika virus transmission: exploring semi-analytical solutions and effective contrls
This paper examined the mathematical model of Zika virus transmission, focusing on the impact of the virus on humans and mosquitoes. Human and mosquito populations involved in Zika virus transmission are divided into two categories: susceptible and infected. In addressing the nonlinear differential equation that governing Zika virus transmission, the Taylor series method (TSM) and the new Homotopy perturbation method (NHPM) were employed to derive semi-analytical solutions. Furthermore, for a comprehensive assessment of the nonlinear system behavior and the accuracy of the obtained solutions, a comparative analysis was performed using numerical simulations. This comparative analysis enabled us to validate the results and to gain valuable insights into the behavior of the Zika virus transmission model under different conditions. Moreover, to decrease the number of infected human population, we analyzed the contact rate of Zika virus transmission between humans and mosquitoes, as well as between humans and humans.

Using a Seminal Likert Scale to Compare the Private Universities in Aleppo City Based on Job Satisfaction
In this research, job satisfaction was evaluated in the four private universities in Aleppo city. After that, the four universities were classified according to each dimension of job satisfaction in this study, which are five basic dimensions: salaries and incentives and annual increases, performance evaluation, the relationship with the direct supervisor and coworkers, the work environment, job stability. The study was conducted on 111 employees at the four private universities, where a job satisfaction questionnaire was distributed and the result were transcribed into the SPSS program, a descriptive analysis of the personal data was conducted, and a five-point Likert scale was also used to describe job satisfaction, then we applied a new algorithm that converts the traditional five-point Likert scale into a form that gives a percentage between 0 and 100 for each dimension of job satisfaction, finally we ranked the four private universities based on this percentage according to each dimension separately.
