Simplified Metrics Calculation for Soft Bit Detection in DVB-T2

The constellation rotation and cyclic quadrature component delay (RQD) technique has been adopted in the second generation terrestrial digital video broadcasting (DVB-T2) standard. It improves the system performance under severe propagation conditions, but introduces serious complexity problems in the hardware implementation of the detection process. In this paper, we present a simplified scheme that greatly reduces the complexity of the demapper by simplifying the soft bit metrics computation having a negligible overall system performance loss

El seguimiento farmacoterapéutico: un componente de la calidad en la atención al paciente

The principal aim of management of the Quality of Care is to assure patient satisfaction, through theactive involvement of health care staff and the incorporation of strategies, whose main aim is to achievecontinuous improvement in clinical activities and to incorporate patient safety as one of its principlecomponents.The management of patient safety is a means to minimizing any possible harm to patients in careprocesses, including the use of medicines. The principles of patient safety can be applied to both levelsof patient care and involve all health care professionals. The risk management is an integral part ofpatient care. Patient safety depends on the solution of problems and the prevention of errors.The pharmacist’s role in patient safety is carried out through Pharmaceutical Care processes and especiallythrough Pharmacotherapy follow-up (PF), which aims to prevent, detect and resolve Drug TherapyProblems (DTP).One of the main difficulties associated with this field is the lack of uniformity of the results obtainedthroughout the different studies carried out, where differences in definitions occur, as in the classificationof drug problems themselves, where process and result are constantly intermingled: Adverse effect,undesirable events, medication errors, DTP, etc.The criteria for classifying such aspects should be uniform, so as to make common information available,which will enable pharmacists to obtain greater knowledge on prevalence, their types, causes, severityand consequences.There is a general desire to improve upon patient safety, to assess the technological processes involvedin evaluating effectiveness and safety, and to certify the establishments and health care professionalsresponsible for such processes.This same approach should also be applied to PF, which is subject to the same basic safety principles.As in the case of all work carried out within the health system, the work of the pharmacist involvesthe professional and ethical responsibility of making his knowledge, experience and methodology availableto his patients. Pharmacists now have the opportunity of making a significant contribution to patientsafety, both in general terms and more specifically in the use of medicines, in a field which is currentlyset for future development.La gestión de la Calidad Total busca la satisfacción del usuario, la implicación activa de los profesionalesresponsables de su salud y la incorporación de estrategias para la mejora continua de las actividadesclínicas, incorporando la búsqueda de la seguridad del paciente como componente principal.La gestión de la seguridad del paciente minimiza las lesiones no intencionadas atribuibles a procesosde la atención sanitaria, incluido el uso de medicamentos. Los principios de seguridad del paciente seaplican en ambos niveles asistenciales y a todos los profesionales sanitarios. Gestionar el riesgo escuidar al paciente. La Seguridad del paciente pretende resolver problemas y prevenir errores.La aportación del farmacéutico a la seguridad del paciente se realiza con la Atención Farmacéutica y enconcreto con el Seguimiento Farmacoterapéutico (SFT) que previene, detecta y resuelve ProblemasRelacionados con los Medicamentos (PRM).Uno de los principales problemas para avanzar, es la dificultad para homogeneizar resultados; existendiferencias en las definiciones, al igual que ocurre en el ámbito del medicamento, donde se mezclapermanentemente proceso y resultado: Efecto adverso, Acontecimiento no deseado, Errores de medicación,PRM, etc.Se ha de homogenizar la taxonomia; disponer de una información común permitiría conocer mejor laprevalencia, sus tipos, sus causas, su gravedad así como sus consecuencias.Se quiere caminar hacia la seguridad del paciente evaluando tecnologías su efectividad y su seguridad,acreditando establecimientos y acreditando competencia profesional.Este es el camino también para el SFT que comparte los principios básicos de calidad de la seguridaddel paciente.El farmacéutico tiene la responsabilidad profesional y ética de poner a disposición de los pacientes elconocimiento, la experiencia y el método, igual que las acciones emprendidas por los sistemas sanitarios.Existe la oportunidad de estar, de ser los responsables de esta aportación, porque la seguridad delpaciente, en general, y en relación al uso de los medicamentos en particular, va a desarrollarse

Adaptation of modified games to characteristics of school physical education

The modified game is considered as a social content of school physical education because it provides respect and interaction with others class mates. There is a relation between students when they are team mates or adversaries. The effects of modified games in the physical fitness and health are also important because of this content in the curriculum of different stages of education. Modified games are divided in four different specialties where there in a peculiarity in all of them. Similarly, the requirement and characteristics of all modified games make this type of games more property to beginning of scholar sport

Conversational affective social robots for ageing and dementia support

Socially assistive robots (SAR) hold significant potential to assist older adults and people with dementia in human engagement and clinical contexts by supporting mental health and independence at home. While SAR research has recently experienced prolific growth, long-term trust, clinical translation and patient benefit remain immature. Affective human-robot interactions are unresolved and the deployment of robots with conversational abilities is fundamental for robustness and humanrobot engagement. In this paper, we review the state of the art within the past two decades, design trends, and current applications of conversational affective SAR for ageing and dementia support. A horizon scanning of AI voice technology for healthcare, including ubiquitous smart speakers, is further introduced to address current gaps inhibiting home use. We discuss the role of user-centred approaches in the design of voice systems, including the capacity to handle communication breakdowns for effective use by target populations. We summarise the state of development in interactions using speech and natural language processing, which forms a baseline for longitudinal health monitoring and cognitive assessment. Drawing from this foundation, we identify open challenges and propose future directions to advance conversational affective social robots for: 1) user engagement, 2) deployment in real-world settings, and 3) clinical translation

The effect of endometriosis on sexual function as assessed with the Female Sexual Function Index: systematic review and meta-analysis

Aim: To systematically compare sexual function between non-treated women with and without endometriosis. Methods: A systematic review was performed on PubMed/Medline, Scopus, EMBASE, Web of Science and Cochrane Library databases searching studies that analyzed sexual function (assessed with the 19-item Female Sexual Function Index [FSFI]), and dyspareunia, chronic pelvic pain and dysmenorrhea (assessed with a visual analogue scale [VAS]) in women with and with endometriosis. Results: In 4 studies, non-treated women with endometriosis presented a higher risk of female sexual dysfunction (mean total FSFI score = 26.55; OR = 2.38; 95% confidence interval [CI] = 1.12, 5.04). Although mean total FSFI scores were not significantly different between women with and without endometriosis (mean difference [MD] = -2.15; 95% CI -4.96, 0.67); all FSFI domain scores were significantly lower in women with endometriosis (n = 4 studies): desire (MD = -0.43; 95% CI -0.57, -0.19); arousal (MD = -0.66; 95% CI -1.15, -0.17); lubrication (MD = -0.41; 95% CI -0.79, -0.02); orgasm (MD = -0.40; 95% CI -0.73, -0.06); satisfaction (MD = -0.45; 95% CI -0.72, -0.18); and pain (MD = -1.03; 95% CI -1.34, -0.72). Women with endometriosis displayed differences (more severity) in terms of VAS scores (2 studies) for dyspareunia (MD = 1.88; 95% CI 0.38, 3.37) and chronic pelvic pain (MD = 2.92; 95% CI 1.26, 4.58); but not for dysmenorrhea. Conclusion: Non-treated women with endometriosis displayed altered sexual function as evidenced by lower scores in all FSFI domains, and severity of dyspareunia and chronic pelvic pain

Spontaneous crystal coalescence enables highly efficient perovskite solar cells

Perovskite solar cells have recently reached staggering efficiencies, through efforts focused on reducing grain boundaries, by enlarging the size of the crystalline domains that constitute the perovskite films. Here, we demonstrate that smaller crystallites within perovskite films spontaneously coalesce into larger ones, even when complete devices are stored in the dark at room temperature. We show that crystal coalescence greatly improves the performance of state of the art perovskite solar cells. Our results reveal the dynamic nature of the morphology of perovskite films and highlight the crucial role that coalescence plays in producing highly efficient device

Fexofenadine is Efficacious and Safe in Children (Aged 6-11 Years) with Seasonal Allergic Rhinitis

Background: This is the first prospective, randomized, doubleblind, placebo-controlled study showing statistical improvement of an H1-antihistamine in children with seasonal allergic rhinitis in all symptoms throughout the entire treatment period. Objective: This randomized, placebo-controlled, parallelgroup,double-blind study was performed to assess the efficacy and safety of fexofenadine in children with seasonal allergic rhinitis. Methods: This study was conducted at 148 centers in 15 countries. Nine hundred thirty-five children (aged 6-11 years) were randomized and treated with either fexofenadine HCl 30 mg (n = 464) or placebo (n = 471) tablets twice a day for 14 days. Individual symptoms (sneezing; rhinorrhea; itchy nose, mouth, throat, and/or ears; itchy, watery, and/or red eyes; and nasal congestion) were assessed at baseline and then daily at 7:00 AM and 7:00 PM (±1 hour) during the double-blind treatment period. Each total symptom score was the sum of all symptoms, excluding nasal congestion. The primary efficacy variable was the change from baseline in the average of the daily 12-hour evening reflective total symptom scores throughout the double-blind treatment. Safety was evaluated from adverse-event reporting, vital signs, physical examinations, and clinical laboratory data at screening and study end point
