This paper presents a comprehensive study that examines the fundamental concept of the non-orthogonal multiple access (NOMA) scheme and provides its detailed comparison with the orthogonal multiple access (OMA) technique. Furthermore, the paper explores the application of the generalized singular value decomposition (GSVD) method in conjunction with NOMA, accompanied by a detailed review of GSVD-based NOMA systems. This study also introduces the concept of mobile edge computing (MEC) and extensively discusses its key parameters. Furthermore, a comprehensive analysis of NOMA MEC is presented, shedding light on its potential advantages and challenges.

Covid-19 en Turquía: aburrimiento en el ocio, resiliencia psicológica, actividad física y estado emocional

This research was conducted in the quarantine process implemented in the CoViD-19 outbreak to examine the relationship between the perception of the boredom of individuals in leisure times and psychological resilience levels, and to describe the leisure activities of individuals, participation in physical activity and emotional state. Accordingly, a total of 2214 voluntary individuals living in Turkey participated with 909 men (41.1%) (age=33.83±10.73), and 1305 women (58.9%) (age=32,41±10.02). Within the scope of the study, information about demographic variables, physical activity and emotional state were collected with the form created by the researchers. In the study, "Leisure Boredom Scale" and "Psychological Resilience Scale" were used as the measurement tools. In the study, individuals were asked to write a word expressing their thoughts on the CoViD-19 process for descriptive analyses, and the collected data were visualized with the "MAXQDA" qualitative data analysis program. In addition, the data are presented in charts in the analysis of other variables. In the statistical analysis of the study, descriptive statistics were used, t-test was used to determine the difference between independent groups, Pearson correlation analysis was used to determine the relationships between variables, and simple linear regression analysis was used to determine the strength of the independent variable in predicting the dependent variable. As a result, predominantly negative emotional states were observed in individuals during the quarantine period. However, as the participation in physical activity increases, the level of psychological resilience will increase and the perception of boredom in leisure time will decrease. Besides, it was found that the perception of boredom in leisure time was an important determinant of the level of psychological resilience, and that it explains about 15% of the variance.Esta investigación se realizó en el proceso de cuarentena implementado en el brote de CoViD-19 para examinar la relación entre la percepción del aburrimiento de los individuos en los momentos de ocio y los niveles de resiliencia psicológica, y describir las actividades de ocio de los individuos, la participación en la actividad física y estado emocional. En consecuencia, participaron un total de 2214 personas voluntarias que vivían en Turquía, con 909 hombres (41,1%) (edad=33,83±10,73) y 1305 mujeres (58,9%) (edad=32,41±10,02).En el ámbito del estudio, se recogió información sobre variables demográficas, actividad física y estado emocional con el formulario creado por los investigadores. En el estudio, la "Escala de aburrimiento del ocio" y la "Escala de resiliencia psicológica" se utilizaron como herramientas de medición. En el estudio, se pidió a las personas que escribieran una palabra para expresar sus pensamientos sobre el proceso CoViD-19 para análisis descriptivos, y los datos recopilados se visualizaron con el programa de análisis de datos cualitativos "MAXQDA". Además, los datos se presentan en gráficos en el análisis de otras variables. En el análisis estadístico del estudio se utilizó estadística descriptiva, se utilizó la prueba t para determinar la diferencia entre grupos independientes, se utilizó el análisis de correlación de Pearson para determinar las relaciones entre las variables y se utilizó el análisis de regresión lineal simple para determinar la fuerza de la variable independiente en la predicción de la variable dependiente. Como resultado, se observaron estados emocionales predominantemente negativos en los individuos durante el período de cuarentena. Sin embargo, a medida que aumenta la participación en la actividad física, aumentará el nivel de resiliencia psicológica y disminuirá la percepción de aburrimiento en el tiempo libre. Además, se encontró que la percepción de aburrimiento en el tiempo libre fue un determinante importante del nivel de resiliencia psicológica, y que explica alrededor del 15% de la varianza.Universidad Pablo de Olavid

Paradoxical para-hisian pacing response

Para-Hisian pacing (PHP) is among the most useful maneuvers in cardiac electrophysiology during sinus rhythm and identifies whether retrograde conduction is dependent on the atrioventricular (AV) node. In this maneuver, the retrograde activation time and pattern are compared during capture and loss of capture of the His bundle while pacing from a paraHisian position. A common misconception about PHP is that it is useful only for septal accessory pathways (APs). However, even with left or right lateral pathways, as long as pacing from the para-Hisian region conducts to the atrium with the activation sequence being analyzed, it can be used to determine whether that activation is AV node–dependent or AP-dependent

A randomized controlled trial of Eye Movement Desensitization and Reprocessing (EMDR) Therapy in the treatment of fibromyalgia

BackgroundIn addition to pharmacological treatment, psychotherapeutic approaches are recommended for the treatment of fibromyalgia. There is a suggestion that eye movement desensitization and reprocessing (EMDR) therapy may be effective. This study aimed to investigate the impact of EMDR therapy on fibromyalgia symptoms, depression, sleep quality, and traumatic stress in fibromyalgia patients through a randomized controlled study (RCT).Materials and methodsThe sample for this study comprised 79 individuals diagnosed with fibromyalgia. Participants were randomly assigned to two groups: the “Treatment as Usual” (TAU) group and the TAU + EMDR group. Prior to the study and at six different time points (before starting the study, at the end of the 5th, 10th, and 15th sessions, 1 month later, and 3 months later), participants completed assessments, including the Fibromyalgia Impact Questionnaire (FIQ), Visual Analog Scale (VAS), Fibromyalgia ACR 2010 Diagnostic Criteria [Widespread Pain Index (WPI) and Symptom Severity Scale (SSS)], Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and Trauma Symptom Checklist-40 (TSC-40).ResultsThere were no differences in the sociodemographic variables between the study and experimental groups. Analysis of variance revealed a statistically significant group effect on VAS (p = 0.019), WPI (p = 0.018), BDI (p = 0.019), and TSC-40 (p = 0.21). After applying Bonferroni correction, EMDR was found to be effective for VAS, WPI, SSS, BDI, PSQI, and TSC-40 (p <0.05).ConclusionThe results of the current study suggest that EMDR therapy is a viable alternative treatment for fibromyalgia. We believe these findings offer robust evidence supporting the efficacy of EMDR therapy in treating fibromyalgia, particularly in the context of a randomized controlled trial (RCT). The application of EMDR therapy for the treatment of patients with fibromyalgia is likely to be beneficial.Clinical trial registrationClinicalTrials.gov, identifier NCT06265194
