The aim of this study is to demonstrate the effect of particle size on semiconductor properties; artificial intelligence is being used for the research methods. As a result, we picked cadmium sulfide (CdS), which is a unique semiconductor material that is employed in a broad variety of current applications. Given that CdS has distinct electrical and optical characteristics, it may be employed in the production of solar cells, for example. Solar cells, as is also well known, have become an essential source of energy in the world. Within the visible range (500-700 nm), we create one layer of bulk CdS and one layer of nano-CdS air bulk CdS air and air nano-CdS air. We used a number of instrumentation methods to investigate the naked CdS nanoparticles, including XRD, SEM-EDX, UV-Vis spectroscopy, TEM, XPS, and PL spectroscopy, among others. The results show that for bulk CdS at normal incidence, the transmittance is T = 45 , and for nano-CdS with particle size 3 nm, the transmittance is T = 85.8 , with transverse-electric (S-polarized) and transverse-magnetic (P-polarized) transmittances of TE = 75 and TM = 80 , respectively.

BACKGROUND: Augmented reality (AR) is capable of facilitating constructive learning through the provision of a learner-centered environment, making for more flexible learning and providing a more distinct experience of learning. AR technology has a significant influence on the teaching approach provided to students with learning disabilities, particularly on their level of self-regulation, and this premise is what motivated the present study. MATERIALS AND METHODS: The research is a quasi-experimental study that adopted a pre- and post-test control group design, involving 24 students who have disabilities. The students were divided into AR group and control group, and data were then exposed to the descriptive statistics and paired sample t test. RESULTS: The results showed that AR technology has a significant effect on the enhancement of the self-regulation of students with learning disabilities. CONCLUSION: The study indicated a significant effect of AR app on the self-regulation skills of students. The study, therefore, encouraged decision academicians to implement technology approaches in the disability setting.

Purpose The level of mental alertness among students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University. The level of self-competence of female students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University. To learn about the relationship between mental alertness and self-competence among students who are in need of study in the preparatory year – Imam Abdul Rahman Bin Faisal University. Design/methodology/approach The researchers used the experimental method by following the experimental design with two measurements, tribal and posterior, for two groups, one experimental and the other control, due to its suitability to the nature of this research. Research sample: the research community included female students stumbling in the scientific path of Rayyan, the second semester of the academic year 2020–2021 AD, where the researchers selected the research sample in a deliberate manner from the stalled students of 25 students and a random sample of 10 female students was withdrawn to conduct the exploratory study. The number of the basic research sample is 15 female students. Reasons for selecting the search sample: all of the sample members are female students stumbling in the scientific path of Al-Rayyan for the academic year 2020–2021 and all sample members agree to apply the research. Findings The researchers refer to this to the virtual psychological guidance program-specific objectives, as well as the follow-up of the scientific principles and principles and the legalization of the measurement tools used in the research and the diversity of the program within the parts of the program and the training sought to develop the ability to manage pressures and emotions and training in social skills, awareness and self-awareness and the use of exercises relaxation, breathing and modern self-help, as well as the use of different methods and techniques such as the method of dialogue, discussion, awareness of feelings and problem-solving, which led to a change in behavior and personal characteristics, which led to a change in behavior and personal characteristics, leading to the development of behavior and personal characteristics. Originality/value The study aims to design a hypothetical psychological counseling program as a method of health care and its effect on the level of mental alertness and the level of self-efficacy of students who have struggled to study at the Deanship of the preparatory year – Imam Abdul Rahman bin Faisal University. The researchers used the experimental approach and applied this study on a sample of 25 students from the students who failed to study at the Deanship of the preparatory year for the second semester of the academic year 2020–2021 AD and the most important results were that the psychological counseling program as a method of health care had a positive effect on improving the level of mental alertness and the level of self-efficacy among the students who had failed to study. There is a positive correlation between the level of mental alertness and self-efficacy of struggling students as a way of health care.

Special education settings have experienced technological innovation that have advanced the development of various skills. Gamification is increasingly used to enhance the skills of individuals with special needs. There have been some studies and limited systematic reviews of gamification in general and special needs settings in particular, however, gamification design applied to special needs lacks a comprehensive systematic review. This article conducts a Literature review of gamification in special needs settings to investigate the effect of gamification in special needs as well as to identify gamification domains, groups and trends for individuals with special needs. Valuable data has been highlighted concerning the technology techniques used in enhancing the skills of individuals with a disability. However, further studies are still needed to examine areas, where research is lacking in the gamification field. The preferred reporting items for literature reviews and meta-analysis PRISMA standard was adopted for inclusion and exclusion criteria’ in this study such as including, eligibility, screening, dentification, and inclusion and exclusion steps. The results revealed that gamification design facilitates the development of various skills among individuals with special needs. Additionally, gamification design was mostly used to enhance the learning skills of individuals with a disability.
