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.

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.

Purpose: Sodium Valproate (VPA) is one of the first-generation Antiepileptic Drugs (AEDs) which mediates epileptic activities by releasing stimulators of Gamma-Aminobutyric Acid (GABA) and is greatly used to treat partial and generalized seizures. Lamotrigine )LTG( is commonly used as AEDs that are widely utilized in first-line monotherapy or in combination with other AEDs. Our specific goal was to compare these two AEDs with different molecular mechanisms on both cortical and subcortical brain structures, along with cognitive performance and dysfunctions. Materials and Methods: We conducted a retrospective study comparing LTG with sodium VPA, both administrated as monotherapy. Twenty patients with a confirmed generalized-epilepsy tonic-clonic seizure who had been treated at least 6 months with LTG (n=8) and Sodium VPA (n=12) were retrospectively recruited. We also included 12 age, gender, and education-matched Healthy Controls (HC). We evaluated cognitive performances. All participants underwent a Magnetic Resonance Imaging (MRI) scanner and T1-weighted MR images were acquired. Voxel-based morphometric alterations in the brain cortex, as well as subcortical structures, were inspected using Statistical Parametric Mapping (SPM) software. Results: The cognitive performance was revealed inferior in patients on Sodium VPA. Poor performance was associated with significant volume reduction in insula bilaterally, and subcortical structures of thalamus, cerebellum, and hippocampus compared to the HC. Comparing patients on LTG to HC revealed significant volume reduction in the anterior cingulate cortex in concordance with slight cognitive dysfunctions. Conclusion: These findings suggested that different molecular mechanisms of Antiepileptic Drugs (AEDs) may affect brain structures and cognition with different severity levels, presumably with more adverse effects induced by GABA mediations from sodium VPA.

AbstractThe aim of this study was to investigate the validity, reliability and factor structure of the "How I Think" questionnaire to assess cognitive distortions in Iranian students. The present research design is descriptive and psychometric studies. The statistical population of this study included all male high school students in city Dezful in the academic year 1399-1400, from which 316 students were selected by multi-stage random sampling and completed the How I think and Bass and Perry Aggression Questionnaires (for Convergent validity). Factor analysis, Cronbach's alpha and Pearson correlation were used to analyze the data using SPSS and AMOS 20 software. The results of factor analysis showed that the questionnaire consists of six factors and has good fit indices. The convergent validity of this questionnaire indicated a satisfactory correlation between the dimensions of the scale "How I think" with the Aggression Questionnaire (p <0.01). Cronbach's alpha and Split- half coefficients for the whole scale and its dimensions ranged from 0.66 to 0.92.The conclusion is that the Persian version of the "How do I think" questionnaire for measuring cognitive distortions in Iranian students has acceptable psychometric properties and can be used as a valid tool in research, educational and clinical situations.

The purpose of the present study was to investigate the effect of generative learning teaching based to pattern cognitive Load on the memorization math of 7th grade students of in the academic year of 2021- 2022. The research method is quasi-experimental with pre-test and post-test with four groups: two control group and two experimental groups. The statistical population of the study consisted of all 7th grade male and female students of District 2 of Mashhad city that 112 person sample was selected by single stage cluster sampling method. The subjects in the experimental group involved in generative learning based to cognitive Load in 16 sessions and the control group did not receive any interventions. The research instrument consisted of a 20-questions researcher-made test. To analyze the obtained data, Multivariate analysis of covariance and SPSS version 24 software were used. The results showed that generative learning teaching based to approach cognitive Load have a positive and significant effect on 7th grade students' memorization math. Based on the findings, it can be concluded that one of the effective training on math memorization students is the use of generative learning on the based load cognitive pattern.

2Introduction: Considering the importance of agrin, mTOR and AKT proteins in cognitive and physiological function, knowing the effects of different exercise programs is of particular importance. Aim: The purpose of this study was to investigate the responses of agrin, mTOR and AKT proteins in dual resistance-cognitive exercises of healthy people. Method: The research method is semi-experimental. 10 healthy men were randomly divided into two groups (resistance-cognitive group of 5 people and resistance group of 5 people). Resistance contraction included eccentric and concentric knee extension with maximum strength and speed. The contractions included 12 sets of 10 repetitions for the right leg, and in the cognitive group, cognitive task exercises included counting numbers in reverse, multiplying and dividing numbers, counting the months of the year, and counting coins simultaneously with facial resistance exercises. Took A biopsy was performed at the beginning and end of the study. To analyze the data, dependent t statistical method and covariance test were performed in SPSS21 software. Results: The results showed that the intra-group changes of mTOR and AKT proteins after one activity session were significant in the resistance-cognitive and resistance groups (p≤0.05). However, the inter-group changes of agrin, mTOR and AKT proteins showed no difference between the two groups. Conclusion: The present study showed that a session of resistance and resistance-cognitive activity leads to changes in the factors involved in the strength and hypertrophy of skeletal muscles. In addition, these changes are generally more resistance-cognitive in the resistance group.

Introduction: As the traffic is one of the most common social troubles in big cities, widen the roads; culture and using the intelligent methods are using to control the traffic. Therefore, the traffic control systems are innovated. These system operators have to do many cognitive jobs to manage these systems. CWA as a framework to improve the design of these systems has introduced in this paper to analyze them.Material and Methods: CTA recognizes the restrictions of system throughout the 5 phases that begin with work domain analysis and ends in necessary personal qualification. Task analysis, strategy analysis and investigating the cooperation and organizations are between paces, respect.Results: the results of this investigation consist of outline of the technique CWA, work domain analysis, decision ladders, details of relevant indicators, strategies, Information Flow Map (IFM), to frame the social organization and cooperation, and worker qualification analysis.Conclusion: The results of this study may used in selection and training the mentioned systems operators. The main reason is to use the experienced staff with high cognitive abilities in working with these systems. Otherwise, it can result in waste the organization money and energy. The operator decision making is more dependent on the information process, the operator also needs to have higher cognitive abilities. Strong visual search, timing and problem solving are perquisites of this job opportunity.

The present research is aimed to analyses the morphological typology of Persian on the basis of the framework of Distributed Morphology (DM). According to the findings of DM, the predominant tendency of Persian's morphological type is defined here on a two-dimensional chart; a chart provided by Aikhenvald (2007) from the conjugation typology of languages, which itself was defined on the basis of the criteria proposed by Sapir. The horizontal axis in this diagram deals with the degree of internal complexity of words and its horizontal axis includes the transparency of morphological boundaries between the morphemes within a grammatical word. Accordingly, the main research questions are to determine: the position of Persian language on the basis of “ degree of internal complexity of words” , as well as, its typology on the basis of “ border transparency criteria” . To analyses the grammatical structures of Persian, a variety of diverse structures, among different Persian text types, including stories, textbooks, scenarios, and research papers was gathered, which contained a total number of nine thousand and six hundred words. The investigation on the first question on the basis of Greenberg’ s quantitative standards illustrates that, by achieving a number of one thousand and five hundred and six words from the above-mentioned index, the orientation of today’ s Persian language, according to the “ degree of internal complexity of words” or what is called as “ word combinability criteria” , is towards “ analytic” language type. Considering the second question, the research demonstrates that in view of the “ border transparency criteria” for morphemes which indicates ways to connect morphemes, Persian language is more inclined towards “ agglutinating” language type. Finally, it can be concluded that based on the findings of DM, the dominant tendency of morphosyntactic structures of Persian is towards “ agglutinating-analytic” languages. Therefore, the research findings in considering Persian within the DM framework approves its grouping within agglutinating-analytic language types, though in comparison to the previous studies, the reduction of the statistical results here illustrates the main tendency of Persian's morphological type towards analytic languages and its movement towards becoming more analytic.
