•Only 56% of Arab parents plan to vaccinate their children, indicating that there are still some reservations among them.•Many parents are reluctant to vaccinate their children because of the ...vaccine's side effects, efficacy, safety, and scheduling difficulties.•Parents were encouraged to vaccinate their children through a doctor's advice, enough information, public acceptance of the vaccine, and a school district's obligation, among other methods.
The issue around vaccination of children has brought divergent opinions among the populations across the globe and among the Arab population. There has been a low response rate to the calls for vaccination of children and this is reflective of the sentiments which parents may have towards their children being vaccinated. This study aims to explore the parents’ health beliefs, intentions, and strategies towards the COVID-19 vaccine for their children among Arab population.
A cross-sectional study using an online survey from October to December 2021, was carried out in five Arab countries in the Middle East. A reliable health belief model (HBM) including five domains: severity, susceptibility, benefits, barriers and cues to action, was adopted. Chi-square, Mann–Whitney test, and multivariable logistic regression were performed for data analysis.
The survey response rate was 58 % (1154/2000). Only 56 % of Arab parents are intended to vaccinate their children against COVID-19. The mean scores of parental health belief are largely driven by their concern over the vaccine’s side effect (p = 0.001) followed by its efficacy, safety (p < 0.001), and scheduling difficulty (p = 0.029). However, strategies that were statistically encouraged parents to vaccinate their children included doctor’s recommendation, adequate information being provided, and acceptance of the vaccine by public (p < 0.001). Parents with one child were almost three times most likely to vaccinate their children (OR = 2.660, 95 %CI = 1.572–4.504, p < 0.001). Parents' desire to vaccinate their children is also influenced by other factors such as job loss owing to COVID-19 and the presence of a health worker in the family.
Intention of Arab parents to vaccinate their children via COVID-19 vaccine is still limited. Thus, it is essential for health care authorities to avail the information which will debunk the erroneous beliefs which some parents have developed towards the vaccination of children against COVID-19.

represents low refractive index and other material in each group represent high refractive index. A cold mirrors are a special dielectric mirrors that reflects the entire visible wavelength band, while the transmitting infrared wavelength band. These systems of mirrors are constructed for an event angle from 0° to 45° and are modeled with interference filters-like multi thin layer dielectric coatings. The results of our work designed shows the mirror based on Al As/MgF2 is the most promising design for cold mirror with the highest reflection in the visible region and the highest Transition in the IR region. In the spectrum range of 400-800 nanometers, the average transmission is much less than 1 %, while the average transmission is 95 percent in the wave band 800-2500 nanometer.
Background: 3D conformal radiotherapy 3DCRT technique are used to treat patients with brain cancer. Goal: this study aims to compare conformity and homogeneity indices for eight patients of brain ...cancer by using three-dimension conformal radiotherapy (3DCRT) technique on planning target volume (PTV) located in brain. Methods: Comparative study of Conformity and Homogeneity indices for ten brain cancer patients during period from October 2019 to March 2020 that carried out at ZCC (Zhianawa Cancer Center) in Sulaimany-Iraq. 3DECRT technique was applied to get the heist dosage to the target volume (tumor) and lowest dose to the healthy structures around the tumor. By using Linear Accelerator machine- LINAC, Elekta synergy type with 6MV photon beam. SPSS-version 22 was applied for analyzing and caring out the data measurements. Results: It has been observed from the results, in both techniques the highest conformity and homogeneity indices have the acceptable values, in this study with 3D-CRT plan technique showed that the mean conformity and homogeneity indices were (0.1999 ± 0.03, 0.9457 ± 0.05) respectively. The mean dose values for organs at risk spinal cord and brain stem were (41.98 ± 2.23, 26.01 ± 16.62) respectively, for ten right and left parotid glands were (23.52 ± 3.99, 23.34 ± 3.93) respectively. In both plans, the average dose values for all organs at risk mentioned above were less than tolerance radiation doses. Conclusion: This study also supports that indices of homogeneity and conformity are important tools for improving the long-term quality of life of brain cancer patients using 3DCRT technology.
