Análise da organização da rede de saúde da Paraíba a partir do modelo de regionalização

Este artigo analisa a organização da rede de saúde da Paraíba a partir do modelo de regionalização proposto pelo estado da Paraíba. Material e Métodos: Trata-se de um estudo documental que tomou por base, prioritariamente, o Plano Diretor de Regionalização da Paraíba e os documentos oficiais do Ministério da Saúde que orientam a construção dos mesmos pelos Estados. Resultados: A análise dos dados revelou alguns limites no processo de implantação do PDR/ PB, tais como a ausência de análise das características sociais, econômicas e culturais durante a escolha das sedes das regiões de saúde e a inexistente descrição da organização da assistência à saúde do território estadual. Conclusão: O processo de regionalização e a formulação do PDR da Paraíba não seguiram a Instrução Normativa do Ministério da Saúde em alguns aspectos, desconsiderando as especificidades de cada região de saúde, o que pode resultar em problemas no acesso e na articulação da rede de serviços com vistas à legitimação das regiões de saúde desse Estado

Gestão da cadeia de suprimento e vantagem competitiva: uma análise em setores industriais a partir da visão relacional

This work has as its main purpose to investigate the contribution of supply chain management in order to obtain competitive advantage by companies from the textile industry and from Ceará footwear industry, focusing its analysis mainly in the interorganizational relations (dyadic). For this, the theoretical referential contemplates different explanatory streams of the competitive advantage, detaching the relational perception of the resources theory, as well as, the main presuppositions of the supply chain management which culminates with the development of an analysis sample that runs the empirical study; the one which considers an expanded purpose of the supply chain which includes the government and the abetment institutions as institutional environment representatives. Besides supply chain management consideration as a competitive advantage source, the work also tried to identify other possible competitive advantage sources for the companies of the investigated sectors. It represents a study of multiple interpretive cases, having four cases as a total; meaning two cases in each one of the sectors, which used as a primary data collecting instrument a semi-structured interview schedule. Different methods were used for the data analysis, the content analysis and the constant comparison methods, the analytical procedure originated from the grounded theory research strategy, which were applied the Atlas/ti software recourse. Considering the theoretical referential and the used analysis sample, four basic categories of the work were defined, including its respective proprieties and dimensions: (1) characteristics concerning to the relationship with the supplier; (2) the company relations with the government; (3) the company relations with the abetment institutions and; (4) obtaining sources of competitive advantage. In general, the applied research in the footwear sector revealed that in the relationships of the researched companies related to its suppliers, there is a predominance of the partnership system and the main presuppositions of the supply chain management are applied which contributes for the acquisition of the relational competitive advantage; while in the textile sector, only some of these presuppositions are applied, with little contribution for the relational competitive advantage. The main resource which was accessed by the companies in both sectors through its relationships with the government and the abetment institutions are the tax incentives which, for the footwear companies, contribute for the acquisition of the temporary competitive advantage in relation to the contestants who do not own productive installations in the Northeast region, it also conducts to a competitive parity situation in relation to the contestants who own productive installations in the Northeast region and to the external market contestants; while for the companies of the textile sector, the tax incentives run the companies to a competitive parity situation in relation to its contestants. Furthermore, the investigated companies from the two sectors possess acquisition sources of the competitive advantage which collimate with different explanatory streams (industrial analysis, resources theory, Austrian school and the dynamic capabilities theory), although there is a predominance of the product innovation as a competitive advantage source in both sectors, due to the bond of these with the fashion tendencies

A saúde psíquica de quem faz saúde: uma análise crítica sobre a humanização direcionada ao profissional de saúde

It is noticeable that pressure, tension and overwork are frequent in health professionals routine. The work related to the ward area demands deep attention and surveillance. Because of that, it is essential to have a specific look at the humanization directed at health professionals, considering that taking care of other human beings is the essence of their job. This study has analyzed the psychic health levels, as well as the stress health professionals are submitted to, providing a debate about the humanization in 06 public hospitals (03 of them awarded by actions of humanization, and 03 not awarded) in Rio Grande do Norte state, Brazil. A study with 126 active health professionals (doctors, nurses, psychologists, nutritionists and social workers) in ward areas in their respective institutions was carried out. The thesis presented, with multi-disciplinary characteristic, counted on the support of statisticians (to calculate samples and data analysis), psychologists, social workers and administrators (linked to the human resources sector in each hospital). A cross-sectional study was performed, taking into consideration both quantitative and qualitative factors. The tools used for that were a semistructured questionnaire with socio-demographic characteristics, work and humanization; Lipp's Stress Symptoms Inventory for Adults (ISSL), and the Goldberg s General Health Questionnaire (QSG). The workers are predominantly women (84,9%), married (54,8%), between 46 and 55 years old (40,5%), working in the same institution for more than 20 years (22,2%), and between 16 and 20 years (20,6%), respectively. They work 40 hours a week (71,4%) and have multiple jobs (61,9%). Although most of these individuals global psychic health is in a good level, there are a significant number of people that is gradually getting worse concerning psychic stress (F1) showed by QSG (54,7%), and stress showed by ISSL(42,1%). Observing the categories, nurses (41,5%). Nutritionists (20,8%), doctors and social workers (18,9%), were among the most affected. About general health (F6), 63% of the awarded hospitals and 70% of the not awarded ones, presented good health levels (ranging from 5 to 50%). It was also noticed that, in the groups mentioned above, 25 and 20% respectively, were inserted in scores between 55 to 90%, what means that they are in worsening phase. The fact that the hospital is awarded or well recognized doesn t interfere in health professionals stress level and in their psychic health. Through what was heard from these individuals, it was possible to verify that they know little about humanization, once few of them identify or know that the service they offer is in an adoption process by Ministerial Policies. It was also detected the necessity of developing actions aimed at worker s health. Such results showed the importance of have more investments in programs that are directed to workers well-being, because they deal with other people s health and it is known that it is difficult for them to offer high-quality assistance if there are not suitable physical, psychological and material conditions to help them develop their jobs. As a warning, it is fair to say that investments in actions that provide humanized care to health professionals, mainly concerning preventive care for their health and life quality in their work

Análise da efetividade do transplante renal na qualidade de vida dos receptores no estado do Rio Grande do Norte

This study was developed with the aim of analyzing the effectiveness of renal transplantation on quality of life of kidney recipients in the Rio Grande do Norte State. This is a descriptive study with longitudinal design, panel type with quantitative approach to data analysis. The Quality of Life (QoL) of chronic disease kidney patients before and after kidney transplantation was assessed by the WHOQOL-bref, The population consisted of patients in pre and post-renal transplantation, the sample had 63 patients older than 18 years. The study was conducted after approval by the Research Ethics Committee of the Onofre Lopes University Hospital, Federal University of Rio Grande do Norte, No. CAAE 0008.0.294.000-10. Data collection was performed at a referral center for renal transplantation in Rio Grande do Norte, from May 2010 to May 2013. Data were analyzed using descriptive statistics and presented in tables and graphs. For statistical analyzes, Microsoft Excel XP and SPSS 15.0 software were used. The tests used were simple variance (ANOVA), t-test, Mann-Whitney and Wilcoxon test to compare means, and Spearman correlations. P values <0.05 were considered significant. The demographic data showed a predominance of people between 18 and 45 years (68.2%) with a mean age of 39.9 years (SD 12.2), male (63.5%), married (58.7%), with children (51.0%). Regarding the education level was observed that 49.2% of participants had completed primary school, and most did not engage in any work activity (90.4%) during the study period. Hemodialysis was the predominant renal replacement therapy (96.8%) and the average waiting time for execution of transplantation was 1.9 years (SD 1.9). Comparison of QoL before and after transplantation showed significant differences in all areas analyzed, demonstrating that kidney transplantation had a positive impact on QoL in chronic renal patients undergoing kidney transplantation. Sociodemographic factors did not influence the quality of life in this group of patients, indicating that transplantation was the main factor to explain the improvement in quality of life. Thus, the alternative hypothesis of the study was accept, that there is a significant difference in quality of life before and after kidney transplant. It is expected that the results of this study may contribute to the development of strategies to encourage organ donation and kidney transplantation process

Reconfigurações industriais das regiões metropolitanas do Nordeste: uma análise a partir do emprego formal

Industrial development experienced by Brazil from the 1950s, changed the concentration of population in the country. The process of development of domestic industry, concentrated in urban areas, crowded growing portion of the population.The Southeast region during the first stage of industrialization driven by the state, with the implementation of Plan goals, captained the major industrial projects implemented in the period and became the main industrial center of the country.In the decade from 1960 to 1980 the state action was marked by numerous regional development projects, softening the industrial concentration and Brazilian investment redirected to the Northeast.The second National Development Plan implemented in the 1970s led to major investments Northeast.This period marked the widespread urban growth and institutionalization of the first metropolitan areas in Brazil.The change of this developmental process is altered with the fiscal and financial crisis of the state in the 1980s and 1990s and spending cuts aimed at national development, reorienting the economy to liberal policies of economic liberalization and reduction of activity in the economy.Industrial policy was relegated to local development plans from the 1990s to the federating units fitting the wide use of tax incentives, the "war tax" to the continued industrialization process.In this context of the national economy work seeks to analyze the industrial setting in the metropolitan areas of Fortaleza, Recife and Salvador between 1995 and 2010.Although the metropolitan areas of Fortaleza, Recife and Salvador are the main urban centers of the Northeast, responsible for the advancement of industrial development, reconfigurations occurred between 1995 and 2010 by changing the level of industrial specialization built by regional division of labor in these regions.The work will be carried out by the method of descriptive analysis of the literature review on regional and urban development.Constitute quantitative method as the secondary data analysis of formal employment from the Annual Social Information (RAIS) Ministry of Labour and Employment (MTE).Using data RAIS / MTE analyzes the industrial specialization index using the Locational Quotient (LQ).Thus, it is assumed as a parameter analysis QL> 1, when the region has become specialized in a particular sector or QL <1, when the region does not have expertise in industrial sector analyzed.The conclusion of study indicates that there was in these metropolitan areas maintained the same bias hub.Fiscal policies, the states, was not successful in diversifying the productive structure and the Northeast region itself.This result is demonstrated by the need and dependence on state investments in the region to promote development.Industrial policies of recent years have been positive to meet the objectives of employment generation, but there must be specific policies for better diversification of production, in addition to integrating the economy of the Northeast sector and regionally

Política de formação de professores: uma leitura a partir da análise do programa especial de formação de professores para a educação básica PROEB/UFMA

Study of Teacher Education Policy: a reading from the analysis of Programa Especial de Formação de Professores para a Educação Básica Proeb - aims to analyze the initial teacher training developed by the Universidade Federal do Maranhão - UFMA. Proeb is a policy of in-service training of teachers, formulated and implemented in the context of current educational policies for basic education. This work assumes that the guidelines developed in the last decades of the twentieth century are linked to international organizations that spread in Latin America continent a homogeneous model of training which has as main features to be held in service through the mode the distance and the school as a leading locus. In Brazil, these guidelines are supported on the Law of Directives and Bases of National Education No. 9.394/96 and Report 09/2001, which deals with the Syllabus Guidelines for the formation of Basic Education Teachers. To carry out the study was taken as reference, the syllabus developed for the deployment of Proeb from 1998 to 2002, specifically the proposal operationalized in the Degree Course of Mathematics in the city of Vitória do Mearim in Maranhão. To conduct the study, it was used literature as a way to deepen understanding, clarify and aim the conceptual aspect of the object researched. The documental research was consisted in the analysis of legal documents concerning the reform of education policies, teacher training and pedagogical project Proeb/UFMA and, finally, the semi-structured interviews were used to allow a better understanding of the subjects involved with research. The data analysis has shown that the curriculum designed to operationalize the course of undergraduate mathematics Proeb/UFMA, despite having guidelines that point to the separation of theory/practice dichotomy and establish as a principle work as an educational principle, has an disciplinary curriculum organization that reinforces the instrumental view of the syllabus, not enabling in practice, the execution of their initial proposal. Concerning to the view of graduates on the course, they highlight the weaknesses of the course, but also evidence that it has allowed an improvement of initial training, through the disciplines of the common core syllabus of courses and special training. It is possible seeing in graduates words, that the course have had repercussions in their teaching and improving their integration into the labor market and in the community of Vitória do Mearim. Overall, these developments have indicated evidence of teacher professionalization, although they are incipient. The work has shown that for the professionalization of teachers is introduced, the syllabus of undergraduate teacher education must overcome the traditional view of syllabus and implement contextualized curricula in a multidisciplinary approach involving, in equal proportions, the general education and training specific course. Accordingly, it is believed in need to review the role of the University in the formative process, as well as recovering as part of educational policies, the omnilateral size of teacher education

Análise da adesão ao tratamento e da qualidade de vida de pessoas com úlcera venosa

The therapeutic adherence is still a big problem among people with venous ulcers (VU) because the treatment is long, expensive and demand changes in lifestyle. In this context, this study aims to examine treatment adherence and quality of life (QOL) of people with VU assisted at primary health care. This is an analytical, cross-sectional study with a quantitative approach to treatment and data analysis. The study had the scenario 13 Family Health Units and 02 Units Mixed of Natal. The target population consisted of 44 persons with UV indicated by the teams of the Family Health Strategy between February and April 2014. Three instruments were used: an instrument to characterize the sociodemographic, health and care aspects, the Multidimensional Scale of Adherence Therapy composed of the dimensions: healthy lifestyle, compressive therapy and neurovascular monitoring and the Charing Cross Venous Ulcer Questionnaire (CCVUQ) that evaluates QOL in persons with VU composed by the domains: Total Score, Social Interaction, Domestic Activities, Aesthetics and Emotional State. The study was approved by the Ethics Committee in Research of the Federal University of Rio Grande do Norte, CAAE: 07556312.0.0000.5537. The data concerning the sociodemographic characteristics showed that there was a predominance of females (65.9%), age range as of 60 years (59.1%) and income of up to 1 minimum wage (81.8%). With the characterization of health, it was evident that most people reported chronic diseases (63.6%), sleep more than 6 hours (81.8%), present pain (81.8%), denying alcoholism (86 4%) and smoking (77.3%) and showed a number greater than or equal to 1 (77.3%) recurrences. Concerning the therapeutic adherence was found that in the dimension compressive therapy there poor adherence. No associations between the domains of adherence and sociodemographic and health variables were found. Was observed, however, better adherence among individuals without pain and with higher schooling. When analyzed the averages of the dimensions of therapeutic adherence with the care characteristics there was statistical significance between: adherence to compression therapy and guidance for use of compressive therapy (p = 0.002) and guidance for regular exercise (p = 0.026). Considering the mean of total score of CCVUQ (mean 51.47, SD 18.33) it is observed that the overall QOL of respondents has approximate value of the median of the scale (50). The mean of the domain Social Interaction (mean 44.23, SD 21.38) and Domestic Activities (mean 45.70, SD 23.21) were those who reported better QOL. There were weak correlations but significant between adherence to healthy lifestyle and Domains Total Score (p = 0.012), social interaction (p-value = 0.048), Aesthetics (p-value = 0.025) and Emotional State (0.017) of CCVUQ. From the data analysis it is concluded that among people with UV, there poor adherence to compressive therapy. Furthermore, we found no statistically significant association between treatment adherence and sociodemographic and health characteristics. It is added that there was a correlation between the healthy lifestyle dimension and domains CCVUQ

Turismo de eventos como estratégia no combate à sazonalidade: uma análise na hotelaria de Natal - RN

The aim of this work is to analyse the tourism events and the performance of this segment from market as strategy in the combat of Natal's hotel seasonality, in the executives/managers's vision from this sector. Two searches were realized to turn available this study: Inicialy a bibliographic search involving the concepts associated with the tematic in question so that it arranges the embasament theoric-scientific and a survey from facts through the country search, where it was applicable in the establishments of work's population with the auxiliary from a formulary answered by a personal interview. The analyses techniques through facts were: estatistic descritive and Kolmogorov-smirnov test.Among the results found, it was verified that the main reasons alleged by the hotels to ingress in the segment from the events were the alinement from the competitive company, the diversification in the options in the sense of occupy the establishments during the period of low season and answer to the demand of market. Investigated the profile from the events occured in the Natal hotels referring to the port, public origin , kinds of events and frequency from their realizations, as well as , the capacity from these establishments to attend this segment.It was noticed that in spite of the hotels agree that the events are important estrategies to combat the seasonality, the establishments still suffer with the flutuation, what can be justified from the moment that it's considered that the events also behave from seasonal manner, having more concentration in certain periods from the year. It was evaluated that the main advantage noticed by the realization from the hotels's events is the utilization from alimentation and drinking services, surpassing the advantage from elevation of taxes occupation from the apartments

Análise tecnológica sobre os aspectos ambientais de empreendimentos hoteleiros da Praia de Ponta Negra Natal/RN: um modelo de sistema de gestão ambiental

The present work aimed the elaboration of an environmental study focused on the hotel sector in order to present an analysis of the environmental aspects of Ponta Negra Beach, in Natal, RN, Brazil and also the aspects of the small and medium hotels existing in this area. By means of this work, it is possible to elaborate a model of a simplified System of Environmental Management which can attend to the exigencies required by NBR ISO 14001: 2004, as well as to present economical viability and possibility to be implemented in a way that hotels may converge to the sustainable environmental development of the tourism in Ponta Negra Beach. The research methodology presents itself divided into three items: execution of the environmental characterization of Ponta Negra Beach, by way of technical visits and interpretation of satellite images and cartograms of the main environmental characteristics of the region; execution of the work already made concerning the development, application and interpretation of the evaluation of the environmental aspects of each hotel, considering the hotels and the period of data collection, these used in evaluation, research instrument and a description of the procedure utilized for the analysis of the collected data and the utilized methodology for the elaboration of a model of a simplified System of Environmental Management. In a general way, it has been concluded that the practices executed by hotels in Ponta Negra Beach are impact-like and harmful to the environment. The simple implementation of analysis procedures and control of the environmental aspects could suggestively contribute to the reduction of environmental impacts promoted by the hotel section at this beach and in the nearby areas. It had been noticed that the study contributed to the sensitization of managers concerning the environmental problems since, in many other times, the detected problem was, in fact, the non-acquaintance about the environmental aspects and impacts from those hotels administrators, because of the lack of surveys and studies about the theme. It had also been noticed the arousing of a possible environmental attitude from some managers

Aplicação do método de análise hierárquica na tomada de decisão para adoção de computação em nuvem: um estudo de caso na federação das indústrias do RN

The progresses of the Internet and telecommunications have been changing the concepts of Information Technology IT, especially with regard to outsourcing services, where organizations seek cost-cutting and a better focus on the business. Along with the development of that outsourcing, a new model named Cloud Computing (CC) evolved. It proposes to migrate to the Internet both data processing and information storing. Among the key points of Cloud Computing are included cost-cutting, benefits, risks and the IT paradigms changes. Nonetheless, the adoption of that model brings forth some difficulties to decision-making, by IT managers, mainly with regard to which solutions may go to the cloud, and which service providers are more appropriate to the Organization s reality. The research has as its overall aim to apply the AHP Method (Analytic Hierarchic Process) to decision-making in Cloud Computing. There to, the utilized methodology was the exploratory kind and a study of case applied to a nationwide organization (Federation of Industries of RN). The data collection was performed through two structured questionnaires answered electronically by IT technicians, and the company s Board of Directors. The analysis of the data was carried out in a qualitative and comparative way, and we utilized the software to AHP method called Web-Hipre. The results we obtained found the importance of applying the AHP method in decision-making towards the adoption of Cloud Computing, mainly because on the occasion the research was carried out the studied company already showed interest and necessity in adopting CC, considering the internal problems with infrastructure and availability of information that the company faces nowadays. The organization sought to adopt CC, however, it had doubt regarding the cloud model and which service provider would better meet their real necessities. The application of the AHP, then, worked as a guiding tool to the choice of the best alternative, which points out the Hybrid Cloud as the ideal choice to start off in Cloud Computing. Considering the following aspects: the layer of Infrastructure as a Service IaaS (Processing and Storage) must stay partly on the Public Cloud and partly in the Private Cloud; the layer of Platform as a Service PaaS (Software Developing and Testing) had preference for the Private Cloud, and the layer of Software as a Service - SaaS (Emails/Applications) divided into emails to the Public Cloud and applications to the Private Cloud. The research also identified the important factors to hiring a Cloud Computing provider

Análise das emissões atmosféricas por veículos automotores em Natal-RN

The fast urban occupation of Brazil, mainly from the last decade of 50, a sensible degradation of the quality of the air generated mainly for the activities was verified human beings associates to industrialization. From the past years, the situation has gotten worst in function of the increment of the fleet of vehicles in circulation in the great cities. Being these, in the city of Natal-RN, the ones that offer the biggest contributions to the atmospheric pollution. For atmospheric air to be a finite natural resources, indispensable and essential to the maintenance of the life in the land, is necessary to the implementation of action to improve its quality and to protect the health of the population. With the objective to study relative aspects to the characteristics of vehicles in use, the present study it searchs to analyze the levels of emissions of gases generated for vehicles converted bi-fuels into the modalities: natural gas (GNV), gasoline and alcohol, inspected for ends of register and together licensing to the State Department of Transit. One used the data gotten from inspections carried through for the company System Specialized in Inspection To propagate, in the city of the Natal-RN, capital of the State of Rio Grande do Norte, between 14 of November of 2003 and 30 of December of 2004. The analyzed parameters are established in the resolution nº 07/93 CONAMA. Of a total of 1.517 inspected vehicles, a average of 15,2% of failed was gotten, or either, that they emit levels of pollution above of the limits established for the legislation, below of the national average that is of 20,0%. The analysis of the data discloses that 7.3% of the fleet are converted the GNV; the growth of vehicles converted the GNV into the city is gradual, with a average of increment in last the 4 years of 23,3%; it has a vehicle predominance that has as combustible original to the gasoline (88,2%); the inspected fleet has average age of 8 years of use, considered young for the Brazilian standards, except for the moved one to the alcohol (average of use of 15 years). Moreover, the type of fuel is not the main parameter to define the indices of emissions; the age of the fleet is the parameter most important when emission is analyzed to propagate; the gas that more generates failed in the inspections is the corrected carbon monoxide; the vehicles generate higher indices of emissions in idling for all the fuels; the presence of the catalyser was not reflected, as it expected, in the reduction of emissions of gases toxic, however when analyzed according to year of manufacture, it was observed that for the vehicles manufactured between 1997 and 2004, reduction of 46,0% in the failed of the vehicles equipped with catalyser was gotten. In conclusion, the fleet of the studied sample, in average terms, takes care of to the requirements of Resolution CONAMA nº 07/93. The results gotten for the present study can subsidize action of public administrations that aim at to the improvement and the maintenance of the quality of air in the city of Natal-RN, as, for example, to implant a net of monitoramento of the quality of air
