JML- Based formal development of a Java card application for managing medical appointments

Although formal methods can dramatically increase the quality of software systems, they have not widely been adopted in software industry. Many software companies have the perception that formal methods are not cost-effective cause they are plenty of mathematical symbols that are difficult for non-experts to assimilate. The Java Modelling Language (short for JML) Section 3.3 is an academic initiative towards the development of a common formal specification language for Java programs, and the implementation of tools to check program correctness. This master thesis work shows how JML based formal methods can be used to formally develop a privacy sensitive Java application. This is a smart card application for managing medical appointments. The application is named HealthCard. We follow the software development strategy introduced by João Pestana, presented in Section 3.4. Our work influenced the development of this strategy by providing hands-on insight on challenges related to development of a privacy sensitive application in Java. Pestana’s strategy is based on a three-step evolution strategy of software specifications, from informal ones, through semiformal ones, to JML formal specifications. We further prove that this strategy can be automated by implementing a tool that generates JML formal specifications from a welldefined subset of informal software specifications. Hence, our work proves that JML-based formal methods techniques are cost-effective, and that they can be made popular in software industry. Although formal methods are not popular in many software development companies, we endeavour to integrate formal methods to general software practices. We hope our work can contribute to a better acceptance of mathematical based formalisms and tools used by software engineers. The structure of this document is as follows. In Section 2, we describe the preliminaries of this thesis work. We make an introduction to the application for managing medical applications we have implemented. We also describe the technologies used in the development of the application. This section further illustrates the Java Card Remote Method Invocation communication model used in the medical application for the client and server applications. Section 3 introduces software correctness, including the design by contract and the concept of contract in JML. Section 4 presents the design structure of the application. Section 5 shows the implementation of the HealthCard. Section 6 describes how the HealthCard is verified and validated using JML formal methods tools. Section 7 includes some metrics of the HealthCard implementation and specification. Section 8 presents a short example of how a client-side of a smart card application can be implemented while respecting formal specifications. Section 9 describes a prototype tools to generate JML formal specifications from informal specifications automatically. Section 10 describes some challenges and main ideas came acrorss during the development of the HealthCard. The full formal specification and implementation of the HealthCard smart card application presented in this document can be reached at https://sourceforge.net/projects/healthcard/.

A JML-Based strategy for incorporating formal specifications into the software development process

This thesis presents a JML-based strategy that incorporates formal specifications into the software development process of object-oriented programs. The strategy evolves functional requirements into a “semi-formal” requirements form, and then expressing them as JML formal specifications. The strategy is implemented as a formal-specification pseudo-phase that runs in parallel with the other phase of software development. What makes our strategy different from other software development strategies used in literature is the particular use of JML specifications we make all along the way from requirements to validation-and-verification.

Avaliação da sobrecarga do cuidador informal no desempenho de suas funções à pessoa idosa dependente, no Concelho de Santana

O processo de cuidar do idoso dependente é multidimensional e executado por cuidadores formais e informais. Sempre foi uma função designada à família onde havia divisão de tarefas entre os diversos membros,. O objetivo do estudo foi avaliar a sobrecarga dos cuidadores informais no desempenho de suas funções à pessoa idosa dependente, no concelho de Santana; estimando o nível de dependência dos idosos e determinando a satisfação, as dificuldades, o coping e a sobrecarga dos cuidadores. A população acessível foi constituída por 69 cuidadores informais. O estudo foi, transversal, descritivo - correlacional. O formulário inclui questões de caracterização sociodemográfica e escalas: de satisfação, de dificuldades em cuidar, e de estratégias de coping (Nolan et cols,1998), de percepção da sobrecarga do cuidador (adaptação de Zarit et cols,1983) validadas para Portugal (Sequeira 2007). Utilizou-se a Escala de Barthel (Mahoney; Barthel,1965) para determinar a dependência dos idosos. Dos resultados realçamos: a maioria dos cuidadores é mulher, casada, com escolaridade até o 6º ano, baixo nível sócio económico sendo familiar do idoso cuidado. Dos cuidadores, 38% são-no entre um a quatro anos e 72,5% cuidam 12 horas/dia A etapa do ciclo vital familiar dos cuidadores é o fim da vida (76,8% ). Dos idosos cuidados, 68% era muito dependente. Dificuldades no cuidar incluíram: restrições sociais, exigências e reações ao cuidar e estratégias de coping mais limitadas. Os cuidadores tendiam sentir-se satisfeitos com o cuidado. Não sofrem sobrecarga 36,3 % mas, 63,7% refere-a ligeira e intensa. Nos homens realçou-se a intensa e nas mulheres a ausência de sobrecarga. Ela foi mais significativa entre os analfabetos, os que sentiam dificuldades, os mais carenciados economicamente e que não gozavam de férias. Evidencia-se a importância da intervenção junto aos cuidadores informais por parte da rede formal de apoio para prevenção da sobrecarga.

A teoria de Callista Roy, a nanda-i e o cuidado ao paciente prostatectomizado

Trata-se de um estudo descritivo de caso clínico, com abordagem qualitativa, o qual possui como objetivo estabelecer relações entre os diagnósticos de enfermagem da NANDA-I e os problemas de adaptação segundo o Modelo Teórico de Roy em um paciente prostatectomizado. A coleta de dados ocorreu em um hospital universitário localizado na cidade de Natal-RN, no mês de janeiro de 2011, por meio de um roteiro de entrevista e exame físico. Os diagnósticos que apresentaram relações entre a NANDA-I e o Modelo de Roy foram: dor, ansiedade, constipação, sono, atividade, volume de líquido e infecção. Conclui-se que grande parte dos problemas adaptativos segundo o Modelo de Roy, manifestados pelos pacientes no pós-operatório de prostatectomia, possuem semelhança com os diagnósticos da NANDA-I

Outorga onerosa do direito de construir e dinâmica do mercado imobiliário formal: planejamento e descaminhos na expansão urbana de Parnamirim RN (2008-2010)

The `Outorga Onerosa do Direito de Construir - OODC` (Public Concession of Building Rights), instrument instituted by The City Statute in 2001, has as main objective the recovery of urban property, seeking for a fair distribution the urbanization benefits. The possibility of usage of the OODC instrument is linked to the maximum utilization coefficient, determined to specific areas in accordance to existing infrastructure conditions, further taking into account the formal real estate market, expansion axis and crowding. Being an instrument which establishes values to be paid for a better use of land, it maintains a narrow relation to the real estate, incentivizing or discouraging the crowding in specific areas. The present study investigates the relationship between the criteria for the making of the Public Concession of Building Rights instrument and the dynamics of the formal real estate market. It takes as empiric universe Parnamirim (RN), part of the Natal Metropolitan Area (RN), focusing on the application of the OODC in the period of 2008-2010. It seeks to better understand the necessary basis for the formulation of the instrument, about how it works and its relation to the formal real estate market. It aims to depict the formal real estate market by presenting the production of urban space in Parnamirim in terms of intensity and nature of the real estate, furthermore identifying the licensed properties through the application of the municipality instrument. For the conclusion, it is discussed the criteria for the formation of OODC, its relationship to the dynamics of the formal real estate market and its influencing possibilities in the processes of usage and occupation of land in the context of urban planning

A representação social do cuidado no Programa Saúde da Família na cidade do Natal

The aim of this study was to learn about the social representations of the care provided by the Family Health Program (FHP) in the city of Natal, Brazil and determine how these representations guide the daily actions of doctors, dentists, nurses, nurse s assistants and oral health assistants during the work process. In this sense, we used the theoreticalmethodological approach to the Theory of Social Representations. For data collection, we used the following instruments: a two-part questionnaire, where the first part recorded sociodemographic data and the second part was adapted to the free word association technique (FWAT), which was applied to 90 professionals belonging to 18 FHP units. Interviews were also used as collection instruments. These were based on inductive stimuli and on direct observations of 30 of these professionals. After a superficial reading of the material, we constructed a corpus from which ten categories emerged. To analyze FWAT we used lexicographic analysis, combining frequency and the mean order of responses. The interviews and sociodemographic variables were analyzed using content analysis and descriptive statistical analysis, respectively. The study showed that the central nucleus of the social representation in question is composed of the elements attention, receptivity and love, revealing that the subjects have different understandings of the FHP care process and that the knowledge accumulated in this respect is supported by an approximate vision of the meaning of care. However, traditional elements with trivializing connotations about care predominate, which compromises the development of strategies to overcome traditional practices. In the set of analyses, we were able to capture the invariance of a contradiction: on one hand, professionals know and affirm the importance of providing care for FHP patients; on the other, the experience of daily practice translates into the negation of this concept. In this contradictory context, professionals build gradual and successive syntheses that allow them to act and affirm themselves by associating information from their academic formation, structured knowledge acquired in other experiences, values and symbols of their daily routine. Thus, they shape and reshape themselves, according to what is concretely and specifically required, at the same time both plural and multiple. The composition of the central nucleus indicates that any measure that intends to modify attitudes that is, the daily actions of FHP professionals with respect to care must take into account and give priority to the debate about the redefining of the semantic fields of the central nucleus (love/attention/receptivity and humanization), especially those of love and attention

Avaliação do cuidado na estratégia saúde da família em metrópoles do nordeste brasileiro

Objective: To evaluate the implementation of the Family Health Strategy (FHS) in Brazilian cities of the Northeast, expanding coverage, analyzing the progress, challenges and innovations. Methods: Multicentric Evaluation Research, Studies Baselines in urban centers, using as a case study method. Selected cases of Aracaju, being capital, advanced coverage with extended team, and Fortaleza, capital coverage incipient and minimal staff. In Fortaleza, purposive sample of 11 Units Primary (APS), 03 managers, 53 professionals and 109 users. In Aracaju, 09 units of APS, 02 managers, 36 professionals, and 90 users. Structured interviews for managers, and structured to professionals and users. Descriptive analysis focusing on the political and institutional dimensions, organization and comprehensive care. Results: There was consensus that the ESF is the preferred port users and acts as inducing changes in care. In the case of Fortaleza, the specificities were: care protocols and community activities aimed at chronic conditions (100%) , with greater participation of doctors and nurses (93%) ; conjunction with more complex services, but the teams reported difficulties with the examination center and experts, the long waits and poor access to local services were the main difficulties reported by users., As innovative practice, the therapeutic group of elderly caregivers mentioned by respondents; There was intersectoral initiatives and teams 87 % of users have participated in meetings about health problems. In the case of Aracaju, care protocols were directed to the lines of care and formulated locally, 85 % coverage of the population with FHS counterpart local financing; employees hired by public tender; 70 % of teams with expertise in public health center for continuing education acting; democratization in management; access technologies, welcoming and computerization in different integrated networks, and evaluation matrix. Conclusions: The ESF has promoted access to health care and inclusion of disadvantaged populations. Different perceptions and practices in the organization of care, with distinct trajectories of reorganization. In the case of Fortaleza, predominance of model programs valuing older, with evidence of advances in care practices and teamwork, but restricted to primary care practices and incipient in public policy perspective. In Aracaju, had network integration with technologies related to the family, in which the ESF is consolidated as public policy. It can be argued that the XII APS expanding coverage, exhibited efficacy, despite the challenges inherent to the different degrees of implementation

Uma análise sociodemográfica dos cuidadores formais de idosos institucionalizados no município de Natal/RN, 2012

The aging population and individual have been the subject of a multitude of studies nowadays. This is probably due to the impact of this phenomenon in various sectors of society, like social security, social assistance and public health. The process of aging of the individual imply the demand for specific services, considering the limitations and vulnerabilities of the individual at that stage of life cycle. The growth of the elderly contingent in the last decades raises challenges for policymakers, the family and also for the society at large. In this scenario, long-stay institutions for the elderly (LSIEs) appear as an option to aid and support the elderly and their family, assisting in all or part in the activities of daily living and self-care. Inside these LSIEs we find the professional responsible for the direct care of the elderly, the formal caregiver. In this context, this dissertation presents two main objectives: an analysis of the phenomenon of population aging in a given brazilian municipality Natal / RN, based on the Demographic Censuses of 2000 e 2010; and a social, demographic and economic characterization of the Formal caregiver for the institutionalized elderly in the municipality, evaluating aspects of his quality of life and also analyzing the institutions where they are inserted. Furthermore, we intend to identify demographic, socioeconomic and quality of life factors that are correlated with caregivers quitting the job. The data used in the second part of this work comes from the research project named Long-Stay Institutions for Elderly: abandonment or a family need? . This survey interviewed 92 caregivers in eleven LSIEs in Natal/RN. In the data treatment logistic regressions, cluster analysis and statistical tests were used. The survey revealed that aging in Natal is more pronounced in the older, more traditional districts: Petrópolis, Lagoa Seca and Tirol. It also allowed a broad characterization of the formal caregivers in LSIEs. Most of these professionals are female. The educational level is predominantly complete high school and more. Most caregivers reported being married or in union, or have ever been in a union. Family monthly income is under three times the minimum wage. The mean age is of 37.4 years. The mean time of work as a caregiver was 5.93 years. The associations showed that being woman, not being single, having caregiving training and physical limitations (regarding quality of life) are related to wanting to quit the caregiving job. As for the characterization of the LSIEs, it was found that the philanthropic ones are older and have most (62.5%) of the institutionalized elderly. The institutions managers gave social interaction and affinity with the elderly as the main criteria with which to evaluate and hire caregivers. It is intended with this study to contribute to improving the quality of life of the elderly and their caregiver, providing information on aspects of institutionalization of elderly both in the philanthropic and particular institutions, in Natal/RN; this dissertation may also be used as a starting point for later works
