Manter o património histórico, natural e artístico por muitos anos é de vital importância pois, sem este património, as gerações não poderiam ter conhecimento nem aprender todos os grandes acontecimentos que têm passado ao longo dos anos num determinado país. Para evitar que esse património se perca foi criado o projecto WISE-MUSE, que tem como objectivo principal a conservação preventiva de obras de arte através de monitorização ambiental, usando uma Rede de Sensores Sem Fios (RSSF) quer para recolher dados quer para transmiti-los. Apesar do projecto WISE-MUSE ser relevante para todos os museus, em geral, este foi aplicado ao caso específico do Museu da Baleia, localizado na Ilha da Madeira, em Portugal. Inicialmente, este projecto preocupava-se essencialmente com a monitorização ambiental das salas de exposição e das câmaras frigoríficas, usando uma rede de sensores sem fios distribuídos pelos espaços em questão. Uma RSSF permite obter dados essenciais à preservação das obras de arte num museu, de uma forma fácil e continua. Para tal, foram usados diferentes tipos de sensores para capturar parametros ambientais, tais como temperatura, humidade, luminosidade, CO e CO2. Um dos objectivos principais do projecto WISE-MUSE é conseguir visualizar as medições recebidas pelos sensores sem fios, de uma forma rápida e fiável, para que quando seja detectado algum problema, os responsáveis pelo museu possam actuar a tempo e resolver o problema sem danos maiores. Tendo em vista este objectivo, este trabalho de mestrado consistiu no desenvolvimento de uma aplicação móvel que permita a visualização e análise dos respectivos dados, em tempo real e independentemente do local onde os utilizadores se encontrem, enviando-lhes alertas caso seja detectado algum parâmetro com valores fora do normal. Esta aplicação foi implementada sobre o sistema operativo Android, por ser um dos mais usados por todo o mundo, assim como graças à sua facilidade de utilização quer por parte dos programadores quer por parte dos utilizadores finais.

Os utilizadores de transportes públicos enfrentam dificuldades no seu dia-a-dia quando usam o autocarro para deslocar-se. Essas dificuldades passam por atrasos pessoais, por enganos na consulta dos horários das carreiras, entre outros, resultando na perda do autocarro. Este trabalho consistiu no desenvolvimento de uma aplicação móvel para a plataforma Android, tendo como principal objectivo fornecer ao utilizador uma ferramenta leve, rápida e útil para utilizar quando se encontra em movimento. O público-alvo desta aplicação são os utilizadores de transportes públicos da empresa Horários do Funchal, que necessitam de realizar deslocações frequentes, e não têm acesso constante à internet, dentro e fora de casa. Realizou-se uma pesquisa, através de um inquérito divulgado nas redes sociais, aos utilizadores de transportes públicos e, posteriormente, utilizou-se essa pesquisa no processo de brainstorming para construir as ideias para as funcionalidades da aplicação. Também se pesquisaram por outras aplicações com objectivos semelhantes e compararam-se essas com a aplicação desta dissertação. Posteriormente, implementou-se o primeiro protótipo e realizaram-se mais testes com novos utilizadores, que usaram a aplicação no seu dia-a-dia. Após se terem corregido os erros encontrados pelos utilizadores na aplicação, lançou-se uma versão beta online no mercado da Google Play. Os resultados obtidos com esta aplicação comprovam não só que existe a necessidade de uma aplicação destas no mercado, mas também permitiram ainda recolher dados sobre melhoramentos que podem ser feitos na mesma. Ao desenvolver esta aplicação pôde-se compreender as necessidades e as limitações que são impostas pelo cliente, como também colocar em prática os conhecimentos adquiridos ao longo do curso.

O desenvolvimento das Tecnologias da Informação e Comunicação (TIC) têm revolucionado a sociedade contemporânea, a escola nesse contexto é chamada a incorporar esses recursos não de forma acrítica ou como recurso auxiliar de ensino, mas como potencializador da construção do conhecimento. O Governo brasileiro através de políticas públicas educacionais vêm disseminando o uso das TIC nas escolas através de programas a exemplo do PROINFO e PROUCA, este último visa a distribuição de laptops educacionais na modalidade 1-1 às crianças. Essa pesquisa visa compreender as práticas pedagógicas na perspectiva de sua consideração como sendo ou não efetiva na melhoria objetivada enquanto inovação pedagógica e promoção do protagonismo infanto juvenil. Para tanto, foi necessário verificar se a utilização desse dispositivo móvel tem contribuído para a construção do conhecimento a ponto de permitir considerar as práticas pedagógicas como inovação pedagógica. Trata-se de uma pesquisa qualitativa de cunho etnográfico com análise de conteúdo, utilizando-se entrevistas com 10 professores e 30 alunos e observações participantes, fundamentada na abordagem Construcionista de Seymour Papert, base de sustentação teórica para a análise dos resultados. O estudo evidenciou, categorias, como: construção do conhecimento, mudança de prática, dificuldades e limitações, motivação e fascínio, mobilidade, acesso a internet, habilidades, autonomia, colaboração e autoria, através das quais foi possível compreender o objeto, como uma potencialidade, visto que, a persistência e a busca alternativa se fizeram presentes na superação gradativa das limitações e entraves que se mostraram no decorrer da pesquisa.

Descriptive exploratory study, prospective with quantitative approach, performed on the Medical Regulation Central of SAMU/Natal, aiming to identify the level of professional satisfaction of the members of the nursing team working at SAMU/Natal; and verify the degree of importance attributed by the professionals to each of the components Professional Satisfaction: autonomy, interaction, professional status , work requirements, organizational rules and remuneration. The population was of 60 professionals, with data collected from january to february 2005. We used an instrument translated and validated by Lino (1999) to the portuguese language, the Professional Satisfaction Rate (PSR). The results demonstrate that there was a slight predominance of the female gender (54,9%); aged between 36 and 45 years old (60,8%); married (58,8%), 82,4% with children, 30,8% aged between 05 and 09. Regarding formation, we observed that 78,4% were nursing technicians and 21,6% nurses, formed for 11 to 15 years (17,5%). From the 11 nurses, 09 (81,8%) informed they have specialization, 29,4% of the team has been working for 11 to 15 years on the urgency area, 58.8% works for more than 02 years on SAMU, 72,6% of the team members have fixed work schedules. There was homogeneity on the work shifts: 41,2% on the day shift and 53% on the night shift. Regarding the reason to be working on SAMU, 64% chose to work in the service, and among these 76,3% predominantly perform direct care to the patients, 96,1% like and are satisfied to work in the service. Regarding the remuneration, 90,9% informed they receive 05 to 10 minimum wages; 70% of the technicians informed they receive -2 to 05 minumum wages, 50,1% informed they receive no additional benefit. The analysis of PSR through Cronbach s Alpha Coeficient resulted on the value of 0,94 and through Kendall s Tau Coeficient on 0,87, demonstrating to be a trustworthy instrument to measure the level of professional satisfaction of the SAMU nursing team, in our environment. As for the level of importance attributed to the components of professional satisfaction, we indentified that the nursing team considered the Autonomy component as the most important, followed by the component Remuneration, Interaction, Work Requirements, Work Requirements, Organizational Rules and Professional Status . Regarding the current level of professional satisfaction, we identified they were most satisfied with the Professional Status , Autonomy, Interaction, Remuneration, Work Requirements and Organizational Rules. The real professional satisfaction level, calculated through statistics, however, tells these professionals are more satisfied with Autonomy, Remuneration, Interaction, Work Requirements, professional Status and Organizational Rules. The PSR in our work was of 8,6, indicating the SAMU Natal nursing team has little satisfaction on their work environment

The objective of this work which is characterized as an applied research, with a qualitative exploratory approach and has case study character has been the analysis of the conceptions and dealings of health professionals of SAMU in Natal RN about the attendance of psychiatric urgencies. The information was collected between the months of March and April of 2010, by means of semi-structured interviews, performed with 24 health professionals integrating of SAMU-Natal as well as the usage of direct observation technique, performed in the institution's medical regulation room. Both the number of professionals involved in the interviews and the bringing about of the observations, were determined by saturation methods in qualitative research's information collecting. The interviews and observations were transcribed and submitted to contents analysis technique , more specifically, to thematic analysis, which made possible to reach the deepest levels, that go beyond what has simply been manifest in the speech of the interviewed, getting to the relations among the categories and social structures of the issue of the research. Keeping this in mind, three analysis categories have been built, namely: conceptions and concepts of psychiatric urgencies shared by health professionals in SAMU-Natal; attendances to psychiatric urgencies in SAMU-Natal; and the Brazilian Psychiatric Reformation under the view of the SAMU-Natal's health professionals. Reflection about the analyzed information revealed discussions pertaining to the stigma and prejudice on mental illness, and also, pointed out to some hindrances which impair the attendance to individuals in mental suffering in SAMU-Natal. The interviewed health professionals' conceptions on the individual in psychical crisis involve concepts of unpredictability, aggressiveness and risk, stigmatizing elements and historically associated to the social hazard ideology and need for mentally sicks' segregation. The predominance of these conceptions, seen in health professionals speech, had identifiable reflexes on assistance to psychiatric demands performed by SAMU-Natal, namely: indiscriminate request for military police's presence during psychic crisis intervention, neglect about occasions that involve mental health patients, as well as repetitive assisting practice directed on physical contention, and transportation to psychiatric hospital. Associated to it, the professionals have shown distorted and reductionist understanding about Brazilian Psychiatric Reformation, and, in the majority, haven't lent credibility to present model of attention to mental health, based on psycho-social treatment, pointing their speech to a need for psychiatric patient's internment. In this sense, we notice that the hospital-centered and excluding model conceived by classical psychiatry still remains alive in these health professionals' mentality as a reference to psychiatric urgency's assistance. Therefore, the research revealed a sequence of elements, that make us think about the challenges that health sector and society must face to realize Brazilian Psychiatric Reformation's principles and guidelines

The attention with safety of the patients is important in the quality of the nursing and health care. In the pre-hospital care, such care is essential on site with the purpose of avoiding possible consequences to the individual, ensuring a fast and appropriate care, with improvement of the morbidity and reduction of the mortality. This medical attention is equally associated with the significant risks of adverse events and serious mistakes, which can be reduced with the awareness of the professionals, organization and quality management. It is a descriptive, transversal research, of quantitative approach, with the objective of identifying the risks for the safety of the patient during the mobile pre-hospital care under the view of the nurses, in a city of the Brazilian Northeast. The sample was formed by 23 nurses. The inclusion criteria: to have at least two years of experience and accept to participate on the research. The data collection was done in two steps, first photo collection, through the adapted method of photographic analysis, and the second with the application of questionnaire, divide in two parts: socio-professional data and digital photo punctuation instrument of the patient s safety. The majority of the nurses had an average working time in the mobile pre-hospital care of six years and six months, in the age group of 38 to 53 years old (69,56%) and with Lato sensu specialization (73,91%), being (29,41%) emergency and (29,41%) in intensive care. The (74%) have the Advance Cardiac Life Support (ACLS) and (100%) have the Pre-Hospital Trauma Life Support (PHTLS); (91, 30%) know the thematic safety of the patient. On the pictures it was observed a bigger variability of the categories (risks) where 44% of variance emerged on the first picture of the research. The pictures 4 and 9 with the average below 5 were classified as very insecure, while pictures 7 and 3 with an average above 7, very secure. On the results of risks observed for the patient s safety in the mobile pre-hospital care five categories emerged: organization and packaging of the equipment and materials, routines and specificities in the mobile pre-hospital care, risks on the management of medications, for traumas and infections. Starting from the analysis of these risks, it was proposed ten steps for the safety in the mobile pre-hospital care: 1- Identify the patient; 2- Safety related to prevention of infection; 3- Safety in the management of medications; 4- Safety and standardization of the packaging of equipment and materials; 5- Attention to the specificities of the mobile pre-hospital care; 6- Incentive and value the participation of the patient and family; 7- Promote the communication with the central of regulation; 8- Prevention of traumas and falls; 9- Protect the skin from additional injuries; 10- Understand the benefit of all the equipment in the ambulance. The multiple risks and their emerged combinations on the research indicate a variety of actions to be developed and stimulated, like the use of steps for the patient s safety in the mobile pre-hospital care which contributes with the aid and management of risks, reduction of mistakes, disabilities and death

O The aim of this study was to characterize the occurrence of trauma in the elderly population served by the mobile pre-hospital service, in Natal, Rio Grande do Norte. This is a descriptive, transversal and quantitative approach and whose population consisted of 2,080 trauma victims. The sample, of systematic random type, consisted of 400 elderly people, aged from 60 years old, assisted by the Office of Mobile Emergency in Natal / RN, between January 2011 and December 2012. Data collection began after consent and assent of the institution of a Research Ethics Committee under No. 309 505. It was proceeded to documentary retrospective analysis of records of this service through a form of self-development, validated by expert judges considered reliable (α> 0.75) and valid (CVI = 0.97) in their clarity and relevance. Data were tabulated by the Statistical Package for Social Sciences, version 20.0. The results show that older victims have an average age of 74.19 years old, with a prevalence of female involvement by chronic diseases, especially hypertension, average usage of 2.2 routine medications with vital signs within normal limits. The trauma prevailed during the daytime, in the residence of the victims, north of the city and on weekends. Among the mechanisms of trauma were falls, traffic accidents and physical aggression, whose most common type was brain-cerebral trauma and the main consequences were suture wounds and closed fractures. Basic Support Units were as more driven to pre-hospital care (87.8%) and the main destination place consisted of a referral hospital for emergency of the state (57.5%). Among the most commonly performed procedures by nursing staff immobilization with rigid board and neck collar and the peripheral venipuncture, and the main component used for volume replacement to saline were highlighted. There was a significant relationship between the deaths and the mechanism of injury, mechanism of injury and procedures, except medication administration procedures carried out, except immobilization and unit for service. It is highlighted the prevalence of trauma in the elderly, poor follow-up Pre-Hospital Trauma Life Support protocol and the paucity of records and nursing procedures performed. There is need for a protocol of care specific to elderly trauma victims and education strategies for the prevention of such events

This study aims to identify the concepts of professional nursing team on assistance in urgency and psychiatric emergencies in SAMU in Mossoró/RN, identifying the difficulties in implementing an emergency assistance to the user in psychiatric distress in this service and point strategies in pursuit of consolidation and expansion of comprehensive health care to the public. It is a descriptive research with qualitative and exploratory approach. The subjects were employees of the nursing staff of SAMU of that mentioned municipality. Semi-structured interviews are applied as tool for data collection. It was counted on the consent of the institution where the study was developed and approval by the Ethics Committee in Research of UFRN with CAAE No 17326513.0.0000.5537, besides signing the Informed Free Consent Term by the participants. Data analysis was done by means of thematic analysis proposed by Bardin. Thus , as a result of the research produced the following categories: mechanistic practice; dehumanization of care; need for qualification, barriers to assistance in urgency and psychiatric emergency and strategies in pursuit of comprehensive care, which proceeded in preparing two articles entitled "Nursing care to the emergency room and psychiatric emergencies in the mobile emergency care service" and "Barriers for emergency service and psychiatric emergencies in the mobile emergency care service". In the studied reality it was identified that nursing care offered to users in situations of urgency and psychiatric emergency is made based primarily on the use of chemical and physical restraints, as well as transportation to the general hospital, constantly using the police force support, which meets the guidelines of the Psychiatric Reform and thereby undermining the provision of an effective and humane care. This scenario is worsened by the lack of an organized network of services in mental health, where after the service the user is taken to a general hospital, considering that there is no ready or appropriate psychiatric emergency service as a Center of Psychosocial Care - CAPs III to reference it, thereby precluding the realization of a resolute and comprehensive care. Thus, it is concluded that nursing care is based on biologicist and medicine-centered model advocated by classical psychiatry, and that despite all the advances in psychiatric reform, still guides the mental health care, so the lack of service network organized in hierarchical and mental health, where the user in urgency and emergency service can be watched in full and the guidelines of the psychiatric reform can be realized in practice

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

In order to guarantee database consistency, a database system should synchronize operations of concurrent transactions. The database component responsible for such synchronization is the scheduler. A scheduler synchronizes operations belonging to different transactions by means of concurrency control protocols. Concurrency control protocols may present different behaviors: in general, a scheduler behavior can be classified as aggressive or conservative. This paper presents the Intelligent Transaction Scheduler (ITS), which has the ability to synchronize the execution of concurrent transactions in an adaptive manner. This scheduler adapts its behavior (aggressive or conservative), according to the characteristics of the computing environment in which it is inserted, using an expert system based on fuzzy logic. The ITS can implement different correctness criteria, such as conventional (syntactic) serializability and semantic serializability. In order to evaluate the performance of the ITS in relation to others schedulers with exclusively aggressive or conservative behavior, it was applied in a dynamic environment, such as a Mobile Database Community (MDBC). An MDBC simulator was developed and many sets of tests were run. The experimentation results, presented herein, prove the efficiency of the ITS in synchronizing transactions in a dynamic environment
