Abstract: The increasing demand of usable and accessible products has transformed the software process development. These aspects are a central part of the User Centered-Design (UCD), as a guide to improve the quality of life, to achieve a better understanding, to enlarge the market and to increase the client's satisfaction. In spite of these aspects, the importance of the UCD inside the process of development software only is considered as a final attribute of the product and it has not been considered as an inherent element during the developmentprocess. This application absence is even presented more in theprocesses of development of the Small and Medium Enterprises software producers SME′s SP, that sometimes haven’t a very defined process. The use of techniques of usability and accessibility can be reflected in benefits of time, cost and quality, central axes in the continuity and prosperity of the objectives of the business. This work, still in development, shows the basic principles of the UCD together with the role that can play in the success from a product when it is including in the process of software development.

Neyem,Andrés; Aracena,Cristian; Collazos,César A; Alarcón,Rosa;
Ingeniare. Revista chilena de ingeniería , 2007, DOI: 10.4067/S0718-33052007000300003
Abstract: interpersonal communication involves more than just words; it involves emotion. emotions can be roughly seen as complex organized internal states. awareness of those states would allow human beings to evaluate social information and develop strategic social intelligence and hence, everyday actions convey social meaning and emotion. this paper reports an experience for supporting public-emotion based dialogs, where emotions are expressed, captured and transmitted between distant participants using tangible interfaces. we also exploit the social meaning of an everyday physical object such as a portrait, in order to create affective interfaces. we describe as well, a device that allows emotional awareness and supports the affective interpersonal interaction among people across distance.

Revista Cubana de Medicina Militar , 2013,
Abstract: Introducción: la sacarosa es un producto natural que por sus propiedades se considera bacteriostática, bactericida y estimulante de la cicatrización. En el mercado mundial la venta de medicamentos y otros productos está dominada por los monopolios, por lo que se hace necesario evaluar un producto barato, capaz de disminuir importaciones y que se pueda generalizar su empleo. Objetivos: evaluar la magnitud de la epitelización total de las heridas e identificar las acciones de la sacarosa sobre los grados de maduración de la dermis. Métodos: se realizó un estudio clinicoterapéutico aleatorizado, controlado y no enmascarado en ratas Wistar con lesiones de piel provocadas e infectadas, que permitiera evaluar, desde el punto de vista histológico, los resultados del tratamiento con sacarosa de las heridas infectadas. Resultados: la sacarosa resultó efectiva para curar la infección de las heridas y estimular la cicatrización. Se produjo la completa epitelización de las heridas con seis días de antelación, con respecto a los grupos controles. Con la sacarosa se logró una mejor calidad en la cicatrización al alcanzar un mayor número de heridas el grado III de maduración de la dermis. Conclusiones: se demostró un mejor efecto cicatrizante del azúcar. Se comprobó su actividad antimicrobiana por la capacidad de limpiar las heridas y eliminar el tejido necrótico de estas. Se logró un mayor grado de maduración de la dermis en los animales tratados con azúcar, lo que evidencia una mayor calidad en la cicatrización en las heridas tratadas con azúcar. Introduction: sucrose is a natural product that is considered for its bacteriostatic, bactericidal and stimulating healing characteristics. On the world market the sale of drugs and other products is dominated by monopolies, so it is necessary to evaluate an inexpensive alternative, which is able to reduce imports and which can be generally used. Objectives: to assess the extent of total wound epithelialization and to identify sucrose actions on the dermis maturation degrees. Methods: a clinical therapeutic randomized, controlled, unblinded study was performed in Wistar rats with induced infected skin lesions and, to assess the histological results of sucrose treatment of infected wounds. Results: sucrose was effective in curing the infection in wounds and in promoting healing. There was complete wound epithelization six days in advance, in comparison with the control groups. better healing quality was achieved to reach with sucrose since a greater number of injuries reached grade III of dermis maturing. Conclusions: better

Abstract: Interpersonal communication involves more than just words; it involves emotion. Emotions can be roughly seen as complex organized internal states. Awareness of those states would allow human beings to evaluate social information and develop strategic social intelligence and hence, everyday actions convey social meaning and emotion. This paper reports an experience for supporting public-emotion based dialogs, where emotions are expressed, captured and transmitted between distant participants using tangible interfaces. We also exploit the social meaning of an everyday physical object such as a portrait, in order to create affective interfaces. We describe as well, a device that allows Emotional Awareness and supports the affective interpersonal interaction among people across distance. La comunicación interpersonal requiere más que solamente palabras, involucra emociones. En términos generales las emociones pueden ser vistas como estados internos complejamente organizados. El Awareness de estos estados permitiría a los seres humanos evaluar la información social y desarrollar inteligencia social estratégica y, por lo tanto, las acciones cotidianas estarían te idas de significado social y emocional. Este artículo reporta una experiencia que busca permitir un diálogo basado en emociones expresadas, capturadas y transmitidas entre diversos participantes usando interfaces tangibles. Además, se explota el significado social de objetos físicos y cotidianos como un portarretratos, con el fin de crear interfaces afectivas entre usuarios dispersos geográficamente. En este artículo se describe un dispositivo que permite un tipo de Awareness emocional apoyando la interacción interpersonal y afectiva entre personas distantes geográficamente.

Revista médica de Chile , 2001,
Abstract: Background: Mapuche, Chilean natives, represent approximately 9.8% of Chilean population and in the IX region of the country, they account for 18.4% of population over 15 years old. They preserve some socio-cultural characteristics that make them different to the rest of the population. Aim: To describe the epidemiological characteristics rheumatoid arthritis among Mapuche natives. Subjects and methods: Retrospective review of patients of Mapuche origin with rheumatoid arthritis, seen at Temuco Hospital between 1980 and 1996. Results: Among 308 cases gathered, only 106 (93 women, aged 55 ± 10 years old) complied with 1987 American College of Rheumatology (ACR) criteria for rheumatoid arthritis. The disease began between 29 and 52 years old in 73% of patients and the mean delay in diagnosis was 4.4 years. At diagnosis, 99% had symmetric poliarthritis, 28.3% had either fatigue, fever or weight loss, and 46.9% were in class III or in class IV of ACR-1991. Fifty three percent of patients developed Sicca syndrome, 36% developed nodules, 23% developed Raynaud phenomenon, 11% developed pulmonary involvement, 7% developed vasculitis, 5% developed neurological manifestations and 19% developed ophthalmologic involvement. Rheumatoid factor was positive in 78% and 73% had erosions. HLA DR4 was (+) in 60% of 30 patients. Thirty percent required 3 or more disease modifying drugs and prednisone over 10 mg/day. There was no correlation between functional capacity and several other features of the disease. Conclusions: Mapuche rheumatoid arthritis patients are detected late and have a poor functional capacity at the time of diagnosis. They also have a higher proportion of extraarticular manifestations, more erosions and require more aggressive treatments. (Rev Méd Chile 2001; 129: 253-8).

Abstract: The process of identifying the attributes and relationships considered in an ontology is a complex task because there are many factors involved in the deterioration of environmental quality, the diversity of sources and data dispersion. This work presents an ontology that integrates the data required by an Environmental Quality Synoptic System (EQSS), which to date scatters in different Internet sites and concentrates by different agencies for example INEGI, CONABIO, SEMARNAT, CNA, among others. The methodology process consists of the collection of environmental information in Mexico through the application of computational techniques resulting ontology with environmental knowledge that will be processed by the system EQSS. Among the main advantages is than the selection and structure of information allow the automated generation of results in an environmental statement. The ontology proposal is based on knowledge of EQSS system that is based on the architecture of expert systems and through this important information for decision-making in regard to environmental quality and interaction with Geographic Information System (GIS) is obtained.

Abstract: Introducción: el cáncer de cuello uterino es la segunda causa de muerte en la mujer a nivel mundialy la principal por enfermedades malignas. Estudios cubanos han reportado que más del 12 % de mujeres atendidas en el programa presentaron esta enfermedad, a pesar del programa nacional de detección precoz vigente. Su incidencia pone en evidencia que el control de la enfermedad, aunque constituye un propósito deseado, todavía no ha logrado los objetivos propuestos. Objetivos: hallar la correlación citohistológica, categorizar los grados de lesión y caracterizar el grupo de pacientes. Métodos: estudio de evaluación retrospectivo a pacientes atendidas en la Clínica de Especialidades Médicas de Bayamo con lesiones preinvasivas del cuello uterino desde enero del 2010 a junio del 2011. El universo fueron 246 citologías anormales y la muestra 89 resultados histológicos con cualquiera de los tres grados de neoplasia intraepitelial cervical obtenidos, se calculó la sensibilidad y especificidad para determinar la efectividad del diagnóstico histológico. Resultados: predominaron las neoplasias intraepiteliales cervicales grado I en los resultados citológicos e histológicos. La mayoría de las pacientes estaban en el grupo de 25 a 39 a os. La sexarquia precoz y la evidencia del virus del papiloma humano (VPH) fueron muy frecuentes. La correlación de la citología y la histología en el diagnóstico hallada fue del 64,1 %, con una sensibilidad del 90,3 % y una especificidad del 79,3 %. Conclusión: la correlación diagnóstica entre la citología y la histología fue efectiva. Introduction: cervical cancer is the second leading cause of death in women worldwide and the main due to malignant diseases. Cuban studies have reported that over 12 % of women attending the program had this disease, despite a national screening program in place for early detection. Its incidence shows that the control of this disease, although a desired purpose, has not yet achieved the proposed objectives. Objectives: to find the histological correlation quote, to categorize the grade injury, and to characterize the patient group. Methods: it was conducted a retrospective study evaluating patients treated at Bayamo medical specialty clinic from January 2010 to June 2011. These patients had preinvasive lesions of the cervix. The universe was 246 abnormal cytologies and we had a sample of 89 histologic results with any of the three grades of cervical intraepithelial neoplasia obtained. We calculated the sensitivity and specificity to determine the effectiveness of the histological diagnosis. Results: the
