Gestión de la calidad de los servicios de Atención al Cliente en el Centro de Atención Presencial (CAP) de la empresa de telefonía Movistar, ubicado en la ciudad de Jinotepe en el departamento de Carazo

El presente trabajo busca analizar que el servicio al cliente hoy debe ser tenido en cuenta en las empresas como una mecanismo o herramienta de alcances incalculables para que exista un verdadero éxito en la gestión de los gerentes que las presiden. Todos los empresarios deberían considerar a sus clientes como su razón de ser, los clientes tienen su valor y es realmente costoso perderlos. La satisfacción es un estado psicológico, y por tanto subjetivo, cuya obtención asegura fidelidad. La satisfacción del cliente es a la organización, lo que la felicidad es a la persona. Para efectos de esta investigación, este punto de vista resulta muy importante puesto que éste es el tipo de relaciones que tiene la empresa bajo estudio con sus clientes. La calidad del servicio produce beneficios porque crea verdaderos clientes, clientes que se sienten contentos al seleccionar una empresa después de experimentar sus servicios, clientes que tendrán lealtad y hablarán en términos positivos de la empresa con otras personas por lo que para este trabajo es de mucha importancia evaluar la percepción del servicio. Existen varios modelos para evaluar la calidad en el servicio, el modelo propuesto y empleado en este trabajo es el SERVQUAL y el de QFD o CASA DE LA CALIDAD, que permitieron sistematizar la información obtenida de los clientes hasta llegar a definir las características de calidad del servicio. A través del Diagrama de Ishikawa y diagrama de Pareto se detectó el origen del problema y sus causas y se considera oportuno recomendar un plan de mejora que ayudara al CAP a superar sus debilidades

Enhanced dielectric performance of a block copolymer-polythiophene nanocomposite

Dielectric elastomer actuators (DEAs) transform electrical energy into mechanical work. However, despite displaying exceptional features, the low permittivity of elastomers restricts their application. Hence, to overcome this limitation, DEAs are fabricated by dispersing poly(3-methylthiophene acetate) (P3TMA), a polarizable conducting polymer, into poly[styrene-b-(ethylene-co-butylene)-b-styrene] (SEBS), a thermoplastic elastomer with excellent mechanical properties. Although high-quality SEBS:P3TMA films are obtained for all compositions (between 0.5 and 20 wt % P3TMA), their thickness and surface roughness increase with the nano-sized filler content. Moreover, the conducting particles are well integrated into the SEBS network with no evidence of aggregation or significant change in the mechanical properties of the composites. P3TMA, which forms encapsulated conductive domains within the polymeric matrix, improves the dielectric behavior of SEBS:P3TMA by increasing their dielectric constant with low dielectric losses and no current leakage. Thus, indicating the potential future application of these nanocomposites as elastomer actuators or high energy density capacitors.Postprint (published version

Tissue Damage, Temperature, and pH Induced by Different Electrode Arrays on Potato Pieces (Solanum tuberosum L.)

One of the most challenging problems of electrochemical therapy is the design and selection of suitable electrode array for cancer. The aim is to determine how two-dimensional spatial patterns of tissue damage, temperature, and pH induced in pieces of potato (Solanum tuberosum L., var. Mondial) depend on electrode array with circular, elliptical, parabolic, and hyperbolic shape. The results show the similarity between the shapes of spatial patterns of tissue damage and electric field intensity, which, like temperature and pH take the same shape of electrode array. The adequate selection of suitable electrodes array requires an integrated analysis that involves, in a unified way, relevant information about the electrochemical process, which is essential to perform more efficiently way the therapeutic planning and the personalized therapy for patients with a cancerous tumor

Prevalence and genotype distribution of cervical human papilomavirus infection in the pre-vaccination era: a population-based study in the Canary Islands

Objective National Spanish studies show that prevalence of cervical human papillomavirus (HPV) infection in the female population is increasingly frequent, with an overall estimate of 14% in women aged 18–65 years. The objective of this study is to know the prevalence and distribution of HPV types in the female population of the Canary Islands prior to the introduction of HPV vaccines and to investigate the associated clinical and sociodemographic factors.Methods Based on the Primary Health Care database, a sample of adult women (aged 18–65 years) of Gran Canaria (GC) and Tenerife (TF) stratified into nine age groups was carried out between 2002 and 2007. Women were contacted by postal letter and telephone call and were visited in their primary care centre. A clinical-epidemiological survey was completed and cervical samples were taken for cytological study and HPV detection. HPV prevalence and its 95% CI were estimated, and multivariate analyses were performed using logistic regression to identify factors associated with the infection.Results 6010 women participated in the study, 3847 from GC and 2163 from TF. The overall prevalence of HPV infection was 13.6% (CI 12.8%–14.5%) and 11.1% (CI 10.3%–11.9%) for high-risk types. The most frequent HPV type was 16 followed by types 51, 53, 31, 42 and 59. HPV types included in the nonavalent vaccine were detected in 54.1% of infected women. Factors associated with an increased risk of infection were: young ages (18–29 years), the number of sexual partners throughout life, not being married, being a smoker, and having had previous cervical lesions or genital warts.Conclusions It is confirmed that prevalence of HPV infection in the female population of the Canary Islands is high, but similar to that of Spain, HPV 16 being the most frequent genotype. The determinants of infection are consistent with those of other populations
