Encaminhamento óptimo do tráfego em redes Triple Play

A Internet é responsável pelo surgimento de um novo paradigma de televisão – IPTV (Televisão sobre IP). Este serviço distingue-se de outros modelos de televisão, pois permite aos utilizadores um elevado grau de interactividade, com um controlo personalizado sobre os conteúdos a que pretende assistir. Possibilita ainda a oferta de um número ilimitado de canais, bem como o acesso a conteúdos de Vídeo on Demand (VoD). O IPTV apresenta diversas funcionalidades suportadas por uma arquitectura complexa e uma rede convergente que serve de integração a serviços de voz, dados e vídeo. A tecnologia IPTV explora ao máximo as características da Internet, com a utilização de mecanismos de Qualidade de Serviço. Surge ainda como uma revolução dentro do panorama televisivo, abrindo portas a novos investimentos por parte das empresas de telecomunicações. A Internet também permite fazer chamadas telefónicas sobre a rede IP. Este serviço é denominado VoIP (Voz sobre IP) e encontra-se em funcionamento já há algum tempo. Desta forma surge a oportunidade de poder oferecer ao consumidor final, um serviço que inclua os serviços de Internet, de VoIP e de IPTV denominado serviço Triple Play. O serviço Triple Play veio obrigar a revisão de toda a rede de transporte de forma a preparar a mesma para suportar este serviço de uma forma eficiente (QoS), resiliente (recuperação de falhas) e optimizado (Engenharia de tráfego). Em redes de telecomunicações, tanto a quebra de uma ligação como a congestão nas redes pode interferir nos serviços oferecidos aos consumidores finais. Mecanismos de sobrevivência são aplicados de forma a garantir a continuidade do serviço mesmo na ocorrência de uma falha. O objectivo desta dissertação é propor uma solução de uma arquitectura de rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada através de um encaminhamento óptimo ou quase óptimo. No âmbito deste trabalho, é realizada a análise do impacto das estratégias de encaminhamento que garantem a eficiência, sobrevivência e optimização das redes IP existentes, bem como é determinado o número limite de clientes permitido numa situação de pico de uma dada rede. Neste trabalho foram abordados os conceitos de Serviços Triple Play, Redes de Acesso, Redes Núcleo, Qualidade de Serviço, MPLS (Multi-Protocolo Label Switching), Engenharia de Tráfego e Recuperação de falhas. As conclusões obtidas das simulações efectuadas através do simulador de rede NS-2.33 (Network Simulator versão 2.33) serviram para propor a solução da arquitectura de uma rede capaz de suportar o serviço Triple Play de uma forma eficiente, resiliente e optimizada.

Condutas de profissionais que realizam a consulta pré-natal na Estratégia Saúde da Família quanto à detecção, tratamento e acompanhamento da gestante com sífilis

The objective of this exploratory descriptive quantitative study was to analyze the behaviors in the detection, treatment and followup of the pregnant woman with syphilis, by health professionals that conduct the pre-natal consultation in the Family Health Strategy, as to the adherence to the recommendations of the Ministry of Health. The study was conducted in nine municipalites of the Trairi region in the state of Rio Grande do Norte. Data were collected during the months of July through September 2007, by means of a questionnaire with a population of 53 health professionals, 30 nurses and 23 physicians. Data were analyzed by descriptive statistics. The results were organized in three major items: knowledge of the health professionals about the symptomatology of syphilis and their actions in the detection of the disease; actions in the treatment of the pregnant woman with syphilis; and the actions of followup of the desease. We identified that 81,2% of the professionals have knowledge about the symptomatology of syphilis in the pregnant woman;79,2% request the VDRL exam in the adequate intervals and approximately 50% conduct the treatment in conformity with the recommendations of the Ministry of Health. For the followup care of the infected woman, 79,2% request a monthly VDRL examination, 69,8% explain the disease to the pregnant woman, and 20,7% affirm that they conduct a proper reception to the woman.We conclude that the majority of the health professionals have knowledge of the detection, treatment and followup of the pregnant woman with syphilis. However, the actions of some professionals diverge from the conduct procedures recommended by the Ministry of Health, as to the requesting of the examinations, medication prescription and notification of the iesease. This indicates the need for improved

As ações de controle da tuberculose na atenção primária à saúde: a visão do doente

Tuberculosis is a disease of great impact on the world context today. In Brazil, the disease management was directed to the Primary Health Care, due to the determination of the Ministry of Health to decentralize health actions for primary care. Thus, since the actions of diagnosis, treatment and control of the disease should happen in this context, however, there are still many barriers that may hinder the realization of these determinations. This study aims to analyze the development of tuberculosis control activities conducted in the services of primary health care from the patient's vision. This is a descriptive, cross-sectional and quantitative study. The population consists of 517 tuberculosis patients treated in units of Primary Health Care in the city of Natal-RN; the sample consists of 93 TB patients. The collect instrument is structured, based in The Primary Care Assessment Tool (PCAT), validated in Brazil and adapted to assess attention to TB in Brazil, with modifications. This instrument was divided into blocks: the first one describes the socio-demographic information of patients with TB and the second one describes the health services working in control, diagnosis and treatment of TB, and includes issues related to the dimensions of primary care: access, bond, services, coordination of care, guidance to the community and family focus. For quantitative analysis, were built indicators for each item of the instrument. The response patterns are followed according to the Likert scale, which was assigned a value between one and five meant that the degree of preference relation (or agreement) of the statements. Values between 1 and 3 were considered unsatisfactory for the indicator, between 3 and less than 4, regular, and between 4 and 5, satisfactory. The results indicate that 62.37% of patients are male, 27.96% aged 41 to 50 years old, and 34.41% unemployed, with low education and low family income. It was found that the reference hospital services are the front door to the patient (59.14%), and are also the local diagnosis of the disease (72.04%). On access, the conditions satisfactory found are: the number of times the patients need to pick up the health care issue, the marking and the facility to get a consultancy in the HS, assistance provided without harm to the individual's attendance labor and facilities related to the proximity between the residence and services; were considered unsatisfactory conditions related to travel to the HS, and on hours and days of operation of services. As for the cast of services were satisfactory and regular actions related to the request for examination to become viable in the first HS, the availability of pot to perform smear and medicines for the treatment, as well as consultations control and receiving information about the disease and the treatment performed; it is considered unsatisfactory the performance of the home care for patients with TB by the HS that acts as a front door, for implementation of the Directly Observed Treatment (DOT), home visits during treatment, the provision of transportation allowance to the patient and the existence of groups for TB patients. Regarding the coordination of care, resulted in regular the action of referring the patient to other HS to obtain examinations, and as unsatisfactory referral to obtain medications. The relationship bond between patient and health team were considered satisfactory in the majority or regular. As for the family and community focus, is satisfactory only the indicator relating to questions from professionals to the patient about the existence of respiratory symptoms in the family. It is considered that there is need for greater commitment from government entities to the incentives required to TB control, as well as the availability of necessary inputs and training of human resources working in the PHC in the ongoing quest to strengthen primary care, as a place of broader host needs to contact the user with the actions and health professionals. It is recommended the adoption of management mechanisms possible to expand the capacity of the health PHC, promoting the service delivery to the user and ensuring attention to population health.

Validação de conteúdo do instrumento para consulta de enfermagem na visita domiciliar às pessoas com lesão medular: um enfoque no autocuidado

This study aimed to validate the contents of an Instrument for Nursing Consultation in the Home Visit of people with Spinal Cord Injury (INCEVDOP-LM), based on the Self-Care Deficit Theory. The methodological development study was conducted with spinal cord injured (SCI) people ascribed in the Family Health Units the city of Natal/RN/Brazil, and with the nurses of these institutions. The study was conducted from Januray 2012 to January 2013 in two phases: the first aimed to identify the need for self-care of persons with SCI, and the second to develop and validate the INCEVDOP-LM. The first phase consisted of a census study of people with SCI living in Natal/RN. In the second phase, a non-probabilistic convencience sample of subjects was selected to form two groups: First stage - Group 1 of the first stage was comprised by 73 adults with SCI diagnosed with paraplegia or tetraplegia, with cognitive function preserved and that were registered to some family health unit; Group 2 of the Second phase was composed of six experts that were nurses with doctoral formation, scientific experience in the area of technology development or assistance to persons with SCI, and with publications in periodicals Qualis A2. Data collection of the first phase was conducted through home visits of people with SCI that responded three instruments: Questionnaire I (comprised of demographic and socioeconomic variables), The Competency Rating Scale for Self-care (ASA) and the Barthel Index (an instrument for evaluation of functional capacity). The research for the second phase was conducted in two stages: I-construction of the INCEVDOP LM; II-validation of the INCEVDOP-LM. The instrument and an evaluation form were forwarded to the experts for the validation. The correlations between the responses were analyzed by the Kappa test, with accepting values of>0.75. The evaluation criteria were: organization, clarity, simplicity, readability, appropriateness of vocabulary, objectivity, accuracy, reliability and suitability and the positive responses with frequency values of≥90% were considered excellent. The chi-square test was used to investigate the differences between proportions. The study attended to the principles of Human Rights CNS Resolution 196/96. Results were reported by means of four articles derived from the study. The findings indicate that the items that showed disagreement among experts (k=0.02) were diagnoses, interventions and evaluation of the nursing features pertaining to the domains of Nutrition, Hygiene, Elimination, Physical, Social and Psychological, and of the Ability to perform work activities feature. Agreement among the experts were reported for the other items, with kappa ranging from 0.72 to 1. After removing items with disagreement, all criteria achieved excellent rates and no significant differences were observed between the proportions of responses of evaluation of experts (p>0.05). We conclude that the instrument shows validity to serve as a guide for nurses to conduct a systematic consultation during the home visit to people with spinal cord injury, with emphasis on self-care. The instrument must go through other levels of validation when applied in the clinical setting

Estratégias de intervenção utilizadas por enfermeiros da ESF do município de Natal/RN no controle do câncer do colo de útero

Cancer of the cervix (cervical cancer) is the second most prevalent cancer among Brazilian women. The high rates of cervical cancer in Brazil justify the implementation of effective strategies to control this, which include actions to promote health, primary prevention, early detection, screening, treatment and palliative care. Despite the existence of the National Programme for Control of the CCU there was no reduction in the incidence and mortality of this disease in Brazil. The Family Health Strategy (FHS) has the potential to facilitate such control and, in this context, one should consider that nurses play a central role. The study aimed to know the general intervention strategies used by nurses FHS of Natal / RN in CCU control, and how specific: analyzing the knowledge of these nurses on the CCU, the actions developed in the ESF for the control of CCU and identify the difficulties faced by them to perform it. This is a descriptive exploratory quantitative developed through a structured interview guide with 106 nurses who have experience in controlling the CCU in FHS teams of Natal / RN. Data analysis was performed using descriptive statistic s. The results pointed to actions taken in the FHS to control the CCU, collection of cervical cancer screening, health education activities, nursing consultation, referral of suspected cases for medical monitoring and active women with abnormal test result . The actions that were not mentioned by the nurses included: forming groups of prevention and health promotion; expand coverage of exams and office hours of consultations, establishment of alternatives to end the pent-up demand in the health units, participation in treatment or rehabilitation process users with the CCU; interventions for pain management, alliances and partnerships with schools, in dustry and the use of protocols. This study can be seen that the practice nurses partially shares to the CCU in Natal / RN. The participants of this study, when asked about the CCU, specifically for signs and symptoms of disease and risk factors in general showed important gaps. Difficulties such as lack of materials for collection of Pap smear; inadequate physical space in the Health Units; pent-up demand in the service, delay in arrival of the test results; obstacles in the actions of referral and counter-referral and cultural factors make the CCU control is compromised. It is believed in this research contributed to a reflection on the importance of the role of nurses in the development of the ESF control actions CCU, pointing out the factors that affect these. It is important to involve all nurses who comprise the ESF as knowledgeable of the risk factors, signs and symptoms, and existing tools for the early detection of cervical cancer in the pursuit of quality improvement actions to promote women`s health, contributing in planning future interventions that may reduce mortality from this disease in Natal / RN.

Qualidade em serviços de saúde: uma contribuição à definição de um modelo paramétrico e padrão de qualidade do tempo agendado para consulta ambulatorial

This work presents a study in quality of health care, with focus on consulting appointment. The main purpose is to define a statistical model and propose a quality grade of the consulting appointment time. The time considered is that from the day the patient get the appointment done to the day the consulting is realized.

The quality grade proposed could be used to define priority for improvement and as criteria to quality control

Qualidade em serviços de saúde: uma contribuição à definição de um modelo paramétrico e padrão de qualidade do tempo agendado para consulta ambulatorial

The knowledge management has received major attention from product designers because many of the activities within this process have to be creative and, therefore, they depend basically on the knowledge of the people who are involved in the process. Moreover, Product Development Process (PDP) is one of the activities in which knowledge management manifests in the most critical form once it had the intense application of the knowledge. As a consequence, this thesis analyzes the knowledge management aiming to improve the PDP and it also proposes a theoretical model of knowledge management. This model uses five steps (creation, maintenance, dissemination, utilization and discard) through the verification of the occurrence of four types of knowledge conversion (socialization, externalization, combination and internalization) that it will improve the knowledge management in this process. The intellectual capital in Small and Medium Enterprises (SMEs) managed efficiently and with the participation of all employees has become the mechanism of the creation and transference processes of knowledge, supporting and, consequently, improving the PDP. The expected results are an effective and efficient application of the proposed model for the creation of the knowledge base within an organization (organizational memory) aiming a better performance of the PDP. In this way, it was carried out an extensive analysis of the knowledge management (instrument of qualitative and subjective evaluation) within the Design department of a Brazilian company (SEBRAE/RN). This analysis aimed to know the state-of-the-art of the Design department regarding the use of knowledge management. This step was important in order to evaluate in the level of the evolution of the department related to the practical use of knowledge management before implementing the proposed theoretical model and its methodology. At the end of this work, based on the results of the diagnosis, a knowledge management system is suggested to facilitate the knowledge sharing within the organization, in order words, the Design department
