RESUMO
Background/Objectives: Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by elevated motor activity, impulsivity, and attention deficit. Approximately 5% of the population suffers from this disorder. Among the key explanations of ADHD, executive functions play an important role in understanding the symptomatology present in this disorder and in determining the main treatment strategies for affected patients. We present a systematic review that seeks to identify the treatment methods developed to support executive functions in individuals with ADHD. Methods: Articles were analyzed in the SCOPUS, PUBMED, and Science Direct databases. Initially, 739 articles were found. After applying inclusion and exclusion criteria, 30 articles remained and were included in the data extraction process. Results: Among the primary treatments identified, 14 studies propose psychological training for executive functions, 9 studies recommend medication, 5 studies suggest digital interventions, and 1 study advocates for sports as beneficial for executive functions. Conclusions: The data are discussed around the need to develop new proposals to enhance the executive functions of individuals with ADHD, thereby improving their performance in educational, personal, social, and family activities impacted by this disorder.
RESUMO
INTRODUCTION: A lower ability to buffer pulse pressure (PP) in the face of increasing mean arterial pressure (MAP) may underlie the disproportionate increase in systolic blood pressure (SBP) in women from young adulthood through middle-aged relative to men. AIM: To evaluate the contribution of MAP to the change in PP and pressure wave contour in men and women from young adulthood to middle age. METHODS: Central pressure waveform was obtained from radial artery applanation tonometry in 312 hypertensive patients between 16 to 49 years (134 women, mean age 35 ± 9 years), 185 of whom were on antihypertensive treatment. RESULTS: Higher MAP levels (≥ 100 mmHg) were significantly associated with higher brachial and central SBP (P < 0.001), PP (P < 0.001), incident wave (P = 0.005), AP (P < 0.001), and PWV (P < 0.001) compared to lower MAP levels. The relationship between MAP and brachial PP (P < 0.001), central PP (P < 0.001), incident wave (P < 0.001), and AP (P < 0.01), but not PWV, strengthens with age. The age-related increase in the contribution of MAP to brachial PP (P < 0.001), central PP (P < 0.001), and incident wave (P < 0.001) was more prominent in women than in men beginning in the fourth decade. In multiple regression analyses, MAP remained a significantly stronger predictor of central PP and incident wave in women than in men, independent of age, heart rate, and antihypertensive treatment. In turn, age remained a significantly stronger predictor of central PP and incident wave in women than in men, independent of MAP, heart rate, and antihypertensive treatment. CONCLUSIONS: Women of reproductive age showed a steeper increase in PP with increasing MAP, despite comparable increases in arterial stiffness in both sexes. The difference was driven by a greater contribution of MAP to the forward component of the pressure wave in women.

Introduction: Executive functions are a set of mental abilities that allow human beings to consciously regulate their behavior and, in a university setting, will have a significant impact on student success during professional training. Objective: To develop a scale to assess executive functions in a university setting. Method: Using a sample of 1,373 university students from Chile (663) and Ecuador (710) between 17 and 33 years old (Mage = 20.53, SD = 2.34). A study was carried out to analyze the psychometric properties of the instrument using a reliability and validity analysis for a scale that assesses executive functions: conscious monitoring of responsibilities, supervisory attentional system, conscious regulation of behavior, verification of behavior to learn, decision making, conscious regulation of emotions, and management of elements to solve tasks. Results: Adequate internal consistency parameters were found between α = 0.71 and 0.85. The seven executive functions proposed on the scale correlated proportionally between r = 0.42 and 0.62. In the confirmatory factor analysis, good fit indices were obtained in the model of the seven executive functions x2(413) = 1649.14, p = <0.001, CFI = 0.91, SRMR = 0.04 and RMSEA = 0.04. Discussion: The research carried out reaches its conclusion stating that the scale that was developed has the psychometric properties to assess executive functions in the Latin American setting. The results regarding previous research and the contribution made in the line of research of executive functions are discussed.
RESUMO
Assistive technology can help people with disabilities to use computers more effectively and can enable them to access the same information and resources as people without disabilities. To obtain more insight into the factors that can bring about the design of an Emulator of Mouse and Keyboard (EMKEY) to higher levels of user satisfaction, an experimental study was conducted in order to analyse its effectiveness and efficiency. The experimental study involved 27 participants (Mage = 20.81, SD = 1.14) who performed three experimental games under different conditions (using the mouse and using EMKEY with head movements and voice commands). According to the results, the use of EMKEY allowed for the successful performance of tasks such as matching stimuli (F(2,78) = 2.39, p = 0.10, η2 = 0.06). However, the execution times of a task were found to be higher when using the emulator to drag an object on the screen (t(52,1) = -18.45, p ≤ 0.001, d = 9.60). These results indicate the effectiveness of technological development for people with upper limb disabilities; however, there is room for improvement in terms of efficiency. The findings are discussed in relation to previous research and are based on future studies aimed at improving the operation of the EMKEY emulator.

Nowadays, daily life involves the extensive use of computers, since human beings are immersed in a technological society. Therefore, it is mandatory to interact with computers, which represents a true disadvantage for people with upper limb disabilities. In this context, this work aims to develop an interface for emulating mouse and keyboard functions (EMKEY) by applying concepts of artificial vision and voice recognition to replace the use of hands. Pointer control is achieved by head movement, whereas voice recognition is used to perform interface functionalities, including speech-to-text transcription. To evaluate the interface's usability and usefulness, two studies were carried out. The first study was performed with 30 participants without physical disabilities. Throughout this study, there were significant correlations found between the emulator's usability and aspects such as adaptability, execution time, and the participant's age. In the second study, the use of the emulator was analyzed by four participants with motor disabilities. It was found that the interface was best used by the participant with cerebral palsy, followed by the participants with upper limb paralysis, spina bifida, and muscular dystrophy. In general, the results show that the proposed interface is easy to use, practical, fairly accurate, and works on a wide range of computers.

Comparative organizational network analysis makes it possible to identify the similarities and differences between organizations according to the content of their networks. This research is a comparative study of organizational networks based on formal power. To accomplish this goal, networks were developed in three organizations from different sectors with workers distributed in high, middle and operational levels in the organizational hierarchy. For the study, 100% of the workers within the identified networks were included. The results indicated that, considering centrality and connectivity network indices, there were no statistically significant differences between organizations according to formal power network behavior. However, we obtained statistically significant differences in terms connectivity and centrality considering the workers' hierarchy. The representative nodes of high and middle hierarchical levels had higher indices of connectivity and centrality than the nodes representative of the operational level. This study makes it possible to identify the formal roles within networks based on legitimate power, which can serve as a basis for decision-making processes and resource allocations, for the strategic use of the networks created.
RESUMO
Introduction: The learning process of Mathematics is a challenge in Latin America; therefore, it is of vital importance to conduct actions that improve the performance in this science. Methods: This article is reporting on quasi-experimental research, where, through the use of Brain Gym, the objective is to improve: the definition of rational numbers, problem-solving ability, mathematical order relationships, and equivalent fractions. We worked with 67 students between 12 and 14 years old, organized into an experimental group (n = 35) and a control group (no participation group; n = 32). Results: We made pre and post-test measurements and found that the control group students improved in their problem-solving ability F(1,65) = 8.76, p = 0.04, η 2 = 0.12 and equivalent fractions F(1,65) = 4.54, p = 0.03, η 2 = 0.06. Discussion: In conclusion, the importance of applying innovative processes to improve the teaching and learning of Mathematics can be affirmed. It is important to note that both the control and experimental groups improved their learning, however, the experimental group did so to a greater extent than the students in the control group, who received a traditional educational process, and they did learn, but not at the level of the experimental group.
RESUMO
The COVID-19 crisis is among the most disruptive events in recent decades. Its profound consequences have garnered the interest of many studies in various disciplines, including consumer behavior, thereby warranting an effort to review and systematize the literature. Thus, this study systematizes the knowledge generated by 70 COVID-19 and consumer behavior studies in the Scopus database. It employs descriptive analysis, highlighting the importance of using quantitative methods and China and the US as research settings. Co-occurrence analysis further identified various thematic clusters among the studies. The input-process-output consumer behavior model guided the systematic review, covering several psychological characteristics and consumer behaviors. Accordingly, measures adopted by governments, technology, and social media stand out as external factors. However, revised marketing strategies have been oriented toward counteracting various consumer risks. Hence, given that technological and digital formats mark consumer behavior, firms must incorporate digital transformations in their process.
RESUMO
The process of assessing executive functions through behavioral observation scales is still under theoretical and empirical construction. This article reports on the analysis of the factorial structure of the EOCL-1 scale that assesses executive functions, as proposed by the theory developed by Luria, which has not been previously considered in this type of evaluation. In this scale, the executive functions taken into account are error correction, internal behavioral and cognition regulatory language, limbic system conscious regulation, decision making, future consideration of consequences of actions, goal-directed behavior, inhibitory control of automatic responses, creation of new behavioral repertoires, and cognitive-behavioral activity verification. A variety of validity and reliability analyses were carried out, with the following results: (a) an adequate internal consistency level of executive functions between α = 0.70 and α = 0.83, (b) significant convergent validity with a scale that assesses frontal deficits between r = -0.07 and r = 0.28, and (c) the scale's construct validity that proposes a model with an executive central factor comparative fit index (CFI) = 0.93, root mean square error of approximation (RMSEA) = 0.04 (LO.04 and HI.04), standardized root mean square residual (SRMR) = 0.04, and x2 ( 312 ) = 789.29, p = 0.001. The findings are discussed based on previous literature reports and in terms of the benefits of using a scale to assess the proposed executive functions.
RESUMO
Adolescence is a stage of growth and development of great relevance. Unplanned teenage pregnancies can be considered a global public health problem due to the high impact on the present and future of these young people, as well as their possible offspring. The aim of this study was to analyze the relationship between self-esteem, attitudes toward love, and sexual assertiveness among pregnant and non-pregnant teenagers. We also considered whether their pregnancy was planned or not. The study was conducted with 225 women from Ecuador (34.2% pregnant; Mean age = 16; SD = 1.15). We administered self-reported measures such as the Rosenberg Self-Esteem Scale, the Love Attitudes Scale, and the Sexual Assertiveness Scale between 2018 and 2019. Self-esteem was higher in adolescents with a planned pregnancy than in those women whose pregnancy was not planned. Pregnant women reported greater acceptance and endorsement of beliefs related to the myth of "soulmate" in comparison to non-pregnant women. Sexual assertiveness related to the negotiation of the use of contraceptive methods was greater in non-pregnant adolescents than in pregnant girls. We discuss the implications of our findings in terms of sexual education and prevention in the sex education field. This study shows differences in self-esteem, attitudes toward love, and sexual assertiveness between pregnant and non-pregnant adolescents.

OBJECTIVE: The aim of this article is to evaluate the quality of filling in endodontically treated root canals using the lateral condensation technique and modified lateral condensation technique. MATERIALS AND METHODS: Thirty-two single-rooted teeth were divided into two groups that were assigned by simple randomization according to the filling technique. Once the endodontic treatment was performed, a periapical radiograph was taken to assess the quality according to the radiographic density and tomography was taken to evaluate the quality according to the tomographic volume of spaces, compared with the post-preparation biomechanical tomography. Finally, we performed a statistical analysis (Student's t-test) to evaluate whether there were differences between the types of filling. RESULTS: Radiographic radiodensity was 182.89 ± 9.81 and 186.72 ± 6.97 HU for teeth treated with the lateral condensation technique and modified lateral condensation technique, respectively. The void volume was 3.75 ± 2.35 and 2.43 ± 1.18 mm3 for teeth treated with the lateral condensation technique and modified lateral condensation technique, respectively. CONCLUSION: No significant differences were found between the techniques for both filling quality parameters.
RESUMO
Objective: The aim of this research was to analyze the role of monitoring in the causal relationship between inhibitory control and symptoms of combined ADHD. Method: It has been conducted a quantitative investigation of two phases. Results: In the first study, a moderation model was analyzed (N = 144 adolescents with combined ADHD), where monitoring was considered as a moderating variable in the causal relationship between the inhibitory control and the symptomatology of ADHD F(3, 140) = 28.03, p < .001; R2 = .37. In the second study, the model through an experimental study was tested (N = 52 adolescents with and without ADHD) where it was found that adolescents with ADHD improve in their inhibitory control when they receive external support to the monitoring F(1, 50) = 21.38, p < .001, η2 = .30. Conclusion: Results suggest that monitoring compensates the poor performance of inhibitory control in adolescents with ADHD, which is a contribution to the theoretical construction of ADHD and to the treatments proposed for this condition because it goes beyond the classic conception of a causality chain among the deficit of inhibitory control and ADHD symptomatology to propose a new explanation about this disorder, where neuropsychology intervention of monitoring would diminish ADHD's symptomatology impact on adolescents.

Abstract Background: The ADHD Rating Scale IV (ADHD RS IV) is one of the most commonly used scales in attention deficit hyperactivity disorder (ADHD) assessment. Its psychometric properties have been studied in contexts including Europe and North America, however, in Latin America, there is shortage of empirical evidence about validity or reliability reported by teachers on a scholar context. The aim of the research was to analyze the psychometric properties of the ADHD RS IV based on the behavior of students reported by teachers. Material/methods: Three hundred and forty-five students voluntarily participated in this study (162 men and 183 women), aged between 5 and 15 years (Mage = 10.43, SD = 3.61). As instruments of measurement ADHD RS IV, Perception of Differences Test and Go / No-Go experiment were used. Cronbach's alpha, Pearson correlation and confirmatory factor analysis were applied and analyzed. Results: In the results it was found that internal consistency coefficient of RS IV ADHD is between .93 and .97. There is a significant statistically correlation between the scale and the number of successes points in the Perception of Differences Test (r = -.55, p = < .001) and mistakes to stimuli no-go (r = .34, p = .002). The classic ADHD model of two factors had good indicators of goodness of fit x 2 (101) = 321.40, p < .001; CFI = .96; RMSEA = .08 (.07 to .09) and SRMR = .04. Conclusions: The article is finalized highlighting the ADHD RS IV has adequate psychometric properties in order to be applied in the school context.

El modelo clásico de TDAH de dos factores tenía buenos indicadores de bondad de ajuste x 2 (101) = 321.40, p <.001; CFI = .96; RMSEA = .08 (.07 a .09) y SRMR = .04. Conclusiones: El artículo finaliza destacando que la ADHD RS IV tiene propiedades psicométricas adecuadas para ser aplicado en el contexto escolar.
RESUMO
Abstract Background: Inhibitory control has been described as a factor causing difficulties in the regulation present in the ADHD. Objective: The aim was to analyze the relationship between inhibitory control and symptoms of ADHD in a sample of 81 subjects diagnosed with ADHD (Mage=10.05, SD=2.53). Methods: A quantitative, cross-sectional and correlational scope research was carried out. The instruments used were the ADHD RS IV and SIMON experiment. Correlation inferential statistical regression and regression processes were applied. Results: Three regression models were tested, where inhibitory control presents a significant prediction with the (a) attention deficit F (1,79) =20.69, p=<.001, R 2 =.21, (b) hyperactivity and impulsivity F (1, 79) =5.90, p=.01, R 2 =.07 and (c) the combination of both (a+b) F (1, 79) =13.25, p=< .01, R 2 =.14. Conclusions: The findings suggest that inhibitory control is one of the main executive functions that determines the degree of affectation of the symptomatology of the child population with ADHD.

Conclusiones: Los hallazgos encontrados sugieren que el control inhibitorio es una de las funciones ejecutivas principales que determina el grado de afectación de la sintomatología de la población infantil con ADHD.
RESUMO
Resumen El sueño es una de las conductas más importantes para la cognición del ser humano. Tiene entre 4 a 6 ciclos que se caracterizan por presentar diferente actividad electromagnética que hace que se presente una determinada actividad cerebral en cada una de ellas. Cuando el patrón del sueño se afecta, se presentan alteraciones en la vida diaria del sujeto que lo padece, generando un impacto negativo en las actividades que realiza en el medio personal, familiar y social. En este artículo se reporta una revisión teórica del sueño, su actividad eléctrica durante cada una de sus fases, los trastornos del sueño y el impacto de los trastornos del sueño en la vida del individuo. Se concluye resaltando el rol de mantener un equilibrio en el patrón de sueño como un beneficio para la vida diaria del sujeto.
Abstract Sleep is one of the most important behaviors for the cognition of the human being. It has between 4 to 6 cycles that are characterized by presenting different electromagnetic activity that causes a certain brain activity to occur in each of them. When the sleep pattern is affected, there are alterations in the daily life of the subject who suffers it, generating a negative impact on the activities carried out in the personal, family and social environment. In this article we report a theoretical review of the dream, its electrical activity during each of its phases, sleep disorders and the impact of sleep disorders on the individual's life. It is concluded by emphasizing the role of maintaining a balance in the sleep pattern as a benefit for the daily life of the subject.

Conclusions: The data is discussed in relation to the benefits of counting with a reduced scale for its future application in the clinical and health scientific context.
RESUMO
Resumen El modelo de organización cerebral de Luria propone la interacción de tres unidades funcionales para comprender el trabajo que realiza el cerebro humano. La primera de ellas se encarga de la regulación del tono y la vigilia. La segunda de recibir, procesar y almacenar la información. La tercera, y de central interés de la investigación, se encarga de programar, ejecutar y verificar la actividad mental. Para valorar esta teoría se han desarrollado una serie de test neuropsicológicos experimentales, no obstante, no se ha propuesto una escala que, en base a los preceptos teóricos de la tercera unidad funcional, permita valorarla basada en la observación clínica de las conductas de la vida diaria del ser humano. En esta investigación se propone una escala que permita al clínico valorar las habilidades mentales asociadas con la capacidad de programar, ejecutar y verificar la forma más compleja de actividad mental; integradas en la tercera unidad funcional de Luria. Se discute la propuesta realizada, en base al beneficio que se genera el contar con una escala que permitirá valorar esta teoría, en los diferentes ambientes donde se desenvuelve el individuo mediante la acción de las habilidades cerebrales de la tercera unidad funcional.
Abstract Luria's brain organization model proposes the interaction of three functional units to understand the work performed by the human brain. The first of them is responsible for the regulation of tone and wakefulness. The second one to receive, process and store the information. The third, and of central interest of the investigation, is responsible for programming, executing and verifying mental activity. To evaluate this theory, a series of experimental neuropsychological tests have been developed, however, a scale has not been proposed that, based on the theoretical precepts on the third functional unit, allows to assess it based on the behaviors of the daily life of the human being. This research proposes a scale that will allow the clinician to assess the mental abilities associated with the ability to program, execute and verify the most complex form of mental activity; integrated in the third functional unit of Luria. The proposal is discussed, based on the benefit that is generated by having a scale that will allow to assess this theory, in the different environments where the individual develops through the action of the cerebral abilities of the third functional unit.
