Sluggish COGNITIVE Tempo is used to describe a particular type of attention deficit, concentration, and slowness in information processing. The aim of this study was to investigate the psychometric properties of the Sluggish COGNITIVE Tempo Scale (SCTS) of the parent form among Iranian children. The present study is a descriptive study. A sample of 1700 people was selected from the provinces of Tehran, East Azerbaijan, West Azerbaijan, Kurdistan, Fars and Khorasan using cluster sampling method. 122 subjects were excluded from statistical analysis due to incomplete answers to the questionnaires and thus the final sample was reduced to 1578 parents. The confirmatory factor analysis method and internal consistency were used to compute the Sluggish COGNITIVE Tempo Scale factorial validity and reliability, respectively. Also, in order to examine the construct validity of the Sluggish COGNITIVE Tempo Scale, we computed correlations between different dimensions of Sluggish COGNITIVE Tempo Scale with Attention Deficit Subscale of Mental Health Assessment Questionnaire for Children and Adolescents. The results of statistical results showed that this scale has structural validity, criterion and convergence in Iranian society. The results indicate that the scale is three factors and also the validity of the scale using Cronbach's alpha method and retest test after Approved two weeks. According to the findings of the present study, the parent form of the Sluggish COGNITIVE Tempo Scale (SCTS) has a good validity and reliability and it can be used in research related to slow COGNITIVE multiplication in Iranian society.

Background & Objective: In recent years, the prevalence of mental and psychological problems among young people and adolescents has increased significantly. One of the most common problems of teenagers during corona disease is stress and ANXIETY. One of the most important psychological effects is ANXIETY disorders and COGNITIVE avoidance. COGNITIVE avoidance refers to getting rid of a person, action, or object, which temporarily reduces ANXIETY in a person. However, in the long term, it increases the ANXIETY. COGNITIVE avoidance is a coping strategy that expresses a person's COGNITIVE, behavioral, and emotional efforts to manage a specific internal and external situation, prevents people from effectively responding to emotional stimuli, and weakens them in managing their emotions. Therefore, it is not recognized as a strategic and efficient factor. The purpose of this research was to investigate the effectiveness of COGNITIVE rehabilitation on coronavirus ANXIETY and COGNITIVE avoidance in teenagers with coronavirus ANXIETY. Methods: The current research method was quasi–experimental with a pretest–posttest design with a control group. The study population comprised all teenagers with coronavirus ANXIETY living in Yazd City, Iran, in April and May 2021. Of them, 30 qualified volunteers were randomly assigned to the experimental and control groups. The inclusion criteria included their cooperation, written consent of the parents, and not undergoing other special treatments such as drug therapy. The research tools included the Corona Disease ANXIETY Scale (CDAS) (Alipour et al., 2020) and the COGNITIVE Avoidance Questionnaire (ACQ) (Sexton & Dugas, 2008). The COGNITIVE rehabilitation program was implemented in the form of computer games for eight 45–minute sessions three times a week for the experimental group. Data analysis was done using the analysis of covariance in SPSS version 22 software at a significance level of 0.05. Results: The results showed a significant difference between the subjects of the experimental group and the control group in terms of the variable of corona ANXIETY in the posttest (p=0.028). Also, the results regarding the variable of COGNITIVE avoidance showed a significant difference in the posttest between the experimental group and the control group (p=0.023). Conclusion: According to the results of this research about the effectiveness of COGNITIVE rehabilitation in reducing corona ANXIETY and COGNITIVE avoidance, this treatment method is recommended to experts in this field.

We address the throughput maximization problem for downlink transmission in DF-relay-assisted COGNITIVE radio networks (CRNs) based on simultaneous wireless information and power transfer (SWIPT) capability. In this envisioned network, multiple-input multiple-output (MIMO) relay and secondary user (SU) equipment are designed to handle both radio frequency (RF) signal energy harvesting and SWIPT functional tasks. Additionally, the COGNITIVE base station (CBS) communicates with the SU only via the MIMO relay. Based on the considered network model, several combined constraints of the main problem complicate the solution. Therefore, in this paper, we apply heuristic guidelines within the convex optimization framework to handle this complexity. First, consider the problem of maximizing throughput on both sides of the relay separately. Second, each side progresses to solve the complex problem optimally by adopting strategies for solving sub-problems. Finally, these optimal solutions are synthesized by proposing a heuristic iterative power allocation algorithm that satisfies the combinatorial constraints with short convergence times. The performance of the optimal proposed algorithm (OPA) is evaluated against benchmark algorithms via numerical results on optimality, convergence time, constraints’ compliance, and imperfect channel state information (CSI) on the CBS-PU link.
