RESUMO A computação em nuvem é uma realidade pela sua capacidade de disponibilizar e gerenciar recursos computacionais remotos de forma competitiva e escalável quando, comparado com recursos e cenários da computação tradicional. Empresas têm manifestado interesse no uso e na migração de seus sistemas legados e serviços para a computação em nuvem. Entretanto, a literatura tem relatado dificuldades e desafios enfrentados por estas empresas nesta direção. Além disso, também tem sido relatada a dificuldade na seleção de profis-sionais qualificados no mercado para prestar consultoria em planejamento, execução e acompanhamento da migração de sistemas legados para a nuvem, assim como na gestão de serviços já disponibilizados. Esta dissertação tem o objetivo de caracterizar a efetividade do uso de cenários de computação em nuvem em, disciplinas de Análise e Projetos de Sistemas e Sistemas Operacionais, de cursos de graduação em Computação. Estas disciplinas são consideradas estratégicas para a formação de profissionais para atuar em computação em nuvem. Esta dissertação, contemplou as seguintes abordagens: aprendizagem ativa com sala de aula invertida, Goal Question Metric (GQM) e pesquisa-ação para a realização do estudo empírico em sala de aula nas, duas disciplinas citadas acima. Os resultados obtidos apresen-tam evidências iniciais de que recursos de computação em nuvem integrados aos conteúdos das disciplinas selecionadas contribuíram para que os alunos apresentassem um índice razoável de qualificação, somente 57% das turmas se sentiram motivada/comprometida com 59% de participação nas atividades de aprendizagem desenvolvidas em sala de aula, com média de aproveitamente 6. Além disso, os conhecimentos adquiridos pelos alunos podem contribuir para a qualificação do seu futuro profissional em um mercado com demandas crescentes no tema abordado.

ABSTRACT Cloud computing has been a successful paradigm in its goal to provide remote computing resources in a competitive and scalable way when compared to traditional computing sce- narios. Companies have expressed interest in migrating and using cloud services. However, the literature has reported difficulties and challenges faced by companies while migrating their assets to the cloud. In addition, there is also the difficulty in identifying qualified professionals to support companies to plan, perform and monitor the migration of their legacy systems to the cloud. This thesis aims at characterizing the effectiveness of the use of cloud computing scenarios in Software Design and Analysis and Operating Systems undergraduate courses. The thesis describes the use of the following approaches: flipped classroom with active learning, Goal Question Metric (GQM), Action- research. The results provided initial evidence that cloud computing resources integrated to the contents of the aforementioned courses contributed to a reasonable rate of qualification, only 57 % of the classes felt motivated / committed to 59 % participation in learning activities developed in the classroom, with an average of 6. In addition, the knowledge gained and experience with cloud computing resources has the potential to contribute in the qualification of future professionals to meet the needs of organizations regarding the discussed topic.

  • Personal Health Records: the People’S Choice? Lisa Sprague, Senior Research Associate
    Issue Brief – No. 820 November 30, 2006 Personal Health Records: The People’s Choice? Lisa Sprague, Senior Research Associate OVERVIEW — Information technology (IT), especially in the form of an electronic health record (EHR), is touted by many as a key component of meaningful improvement in health care delivery and outcomes. A personal health record (PHR) may be an element of an EHR or a stand-alone record. Proponents of PHRs see them as tools that will improve consumers’ ability to manage their care and will also enlist consumers as advocates for wide- spread health IT adoption. This issue brief explores what a PHR is, the extent of demand for it, issues that need to be resolved before such records can be expected to proliferate, and public-private efforts to promote them. NATIONAL HEALTH POLICY FORUM FACILITATING DIALOGUE. FOSTERING UNDERSTANDING. Issue Brief – No. 820 November 30, 2006 Personal Health Records: The People’s Choice? Take control, health care consumers are exhorted. Don’t risk having your health information swept away in a storm or unavailable when you are taken unconscious to the emergency room. Safeguard yourself and your family. Become empowered! The empowered consumer, a stock character in health-reform scenarios, is not so easily identified in real life. There is a range of reasons for this: A given consumer may be sick or injured or cognitively impaired, thus lack- ing the ability and/or will to exercise choice. He or she may have been conditioned to do what the doctor says without second-guessing. Most commonly, he or she may lack the information that is the coin of empow- erment.

Gichoya2 1Department of BioHealth Informatics, Indiana University–Purdue University Indianapolis, Indianapolis, IN, USA 2Dotter Institute, Oregon Health and Science University, Portland, OR, USA Objectives: Open-source Electronic Health Record (EHR) systems have gained importance. The main aim of our research is to guide organizational choice by comparing the features, functionality, and user-facing system performance of the five most popular open-source EHR systems. Methods: We performed qualitative content analysis with a directed approach on recently published literature (2012–2017) to develop an integrated set of criteria to compare the EHR systems. The functional criteria are an integration of the literature, meaningful use criteria, and the Institute of Medicine’s functional requirements of EHR, whereas the user-facing system performance is based on the time required to perform basic tasks within the EHR system. Results: Based on the Alexa web ranking and Google Trends, the five most popular EHR systems at the time of our study were OSHERA VistA, GNU Health, the Open Medical Record System (OpenMRS), Open Electronic Medical Record (OpenEMR), and OpenEHR. We also found the trends in popularity of the EHR systems and the locations where they were more popular than others. OpenEMR met all the 32 functional criteria, OSHERA VistA met 28, OpenMRS met 12 fully and 11 partially, OpenEHR-based EHR met 10 fully and 3 partially, and GNU Health met the least with only 10 criteria fully and 2 partially.

  • Perceived Value and Barriers to Use of Personal Health Records by Patients in South Africa
    WITS BUSINESS SCHOOL Perceived Value and Barriers to use of Personal Health Records by Patients in South Africa Mia Erasmus A research report submitted to the Faculty of Commerce, Law and Management, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Master of Business Administration Johannesburg 2014 ABSTRACT Context: Electronic PHR is a new concept in South Africa and there is little research of how individuals perceive PHR in South Africa. The study fills a gap in that there are no published PHR utilisation studies done in South Africa, likely due to the fact that there were very few PHR systems available before 2012. Problem statement: Investigate the perceptions of personal health records amongst patients in South Africa. First Sub-problem: The first sub-problem is to determine the perceived value of personal health records to patients in South Africa. Second Sub- problem: The second sub-problem is to determine the perceived barriers to use of personal health records. Method: The research methodology chosen is an online survey with analysis of the ordinal data using the Distribution-Fitting Algorithmic Approach. The research analysed a survey sent by email to registered individual users on the My Healthspace database. Key findings: Perceived value of PHR to patients: 1) PHR had enough interactive features. 2) Respondents likely to access their PHR again. 3) Respondents want to be able to access their health records online. 4) Respondents agreed most with usefulness of access to their summary file. 5) Respondents disagreed with PHR decreasing the need to see their doctor in person.

The thesis consists of two main parts; selecting a suitable Open Source EMRS and developing an instructional unit for training students in order to use the EMRS. The Analytic Hierarchy Process (AHP) was used to select a suitable Open Source EMRS. The training unit uses eLearning, problem-based learning, and case study to optimize the teaching methods. The potential learning objectives are defined by using the Revised Bloom’s Taxonomy method. In the later parts, grading rubrics are created for the evaluation of the students’ learning outcomes, while the quantitative and qualitative data analysis methods are applied to the evaluation of the two questionnaires.
