Esta tese propõe conceitos, processos e uma arquitetura de sistemas para Monitoração e Acompanhamento da Aprendizagem Eletrônica (MAAE). A arquitetura é definida pelo seu modelo conceitual, pela interação com os serviços externos e pela representação XML dos conceitos e dos serviços. Ela independe de abordagem pedagógica específica. O Ponto de Observação é inserido em vários locais do Conteúdo da Aprendizagem Eletrônica. Um Elemento de Observação é associado ao Ponto de Observação, e é o responsável pela captura das interações do Processo de Aprendizagem Eletrônica. O Agenciador de Observação (Agenciador de Monitoração e Acompanhamento da Aprendizagem Eletrônica) recebe os eventos e solicitações dos Elementos de Observação e interage com os serviços externos. Os eventos são gravados no Repositório de Observação. A definição dos Processos de Aprendizagem Eletrônica é útil para a definição da estratégia de monitoração (Modelagem do Processo da Aprendizagem Eletrônica). Através da inserção dos mecanismos de observação nas Atividades de Aprendizagem (Processo da Produção do Conteúdo de Aprendizagem Eletrônica) é feita a monitoração do aprendiz (Processo da Aprendizagem Eletrônica) e se obtém as informações para análise (Avaliação e Análise da Aprendizagem Eletrônica).; This thesis proposes concepts...

A pHmetria esofágica é considerada o melhor método diagnóstico do refluxo ácido gastroesofágico. Contudo, é bastante incômoda e restringe consideravelmente as atividades cotidianas do paciente. A pHmetria sem cateter foi desenvolvida para contornar tais limitações. OBJETIVOS: Comparar as pHmetrias convencional e sem cateter em relação: ao grau de incômodo e limitações das atividades cotidianas, à ocorrência de falhas técnicas relevantes, à capacidade de detecção do refluxo e de relacionar as queixas clínicas com o mesmo. Objetiva-se também, verificar se a monitorização mais prolongada (48 horas) oferece vantagens em relação à monitorização usual (24 horas). MÉTODOS: Foram estudados, de modo prospectivo, 25 pacientes encaminhados para realização de pHmetria esofágica, com sintomas típicos da doença do refluxo gastroesofágico, como queixa predominante. Todos pacientes foram submetidos à entrevista clínica, manometria esofágica e realização, com período inicial simultâneo, de pHmetrias com cateter (24 horas) e sem cateter (48 horas). Foi aplicado questionário para avaliação do grau de incômodo, após o término das pHmetrias. RESULTADOS: Quanto ao incômodo na introdução dos sensores de medida de pH...

Empreendimentos industriais requerem o completo e preciso acompanhamento de dados de máquinas em tempo real, integrando as atividades do chão de fábrica com a engenharia, suporte e de negócios. É reconhecido que sistemas de monitoramento são fundamentais para melhorar a qualidade do produto, reduzir os tempos e para a adaptação rápida às mudanças de produção. Os sensores de processos possuem altos custos, não são compactos e são de difícil implementação. Portanto, seria estratégico desenvolver sistemas de monitoramento que utilizem ao máximo os recursos já existentes nas máquinas ferramentas e que não representem custos adicionais de implementação. O uso de CNC´s de arquitetura aberta nas indústrias é crescente. Estes se mostram como potenciais ferramentas para atender a estas exigências. Possuem os recursos necessários para a aquisição de informações administrativas e tecnológicas e para o desenvolvimento de sistemas de monitoramento. O objetivo do presente trabalho é pesquisar arquiteturas de monitoramento e supervisão para processos de usinagem que tenham como base informações disponíveis em CNC´s de arquitetura aberta. Tais sistemas, apesar de todo o potencial existente, ainda não tem sido explorados nem desenvolvidos adequadamente para os processos de usinagem. O presente trabalho é multidisciplinar nas áreas de automação e usinagem. Está dividido em partes em que são analisados tanto os elementos tecnológicos dos CNC´s abertos...

Participatory monitoring of ecological and socioeconomic effects of harvesting and trading natural resources is advocated as a promoter of natural resource conservation and local communitiy empowerment. Nevertheless, the strategys success depends upon peoples willingness and availability to participate. Yet little is known about the factors that drive local communities to volunteer in participatory monitoring, particularly in relation to small-scale communities living in remote locations. This thesis investigated whether a number of candidate factors were able to predict peoples participation in monitoring. To do so, we conducted a study in a forest community of the Brazilian Amazon that harvested and traded Carapa guianensis (andiroba), a non-timber forest product (NTFP). Two methods of data gathering were employed: (i) an interview-based survey of 166 adults ( 18 y.o.; 51 households) to estimate peoples self-stated intention to participate and the drivers of their participation, and (ii) experimentally-implemented monitoring tasks of the effects of harvesting and trading C. guianensis to measure peoples actual participation. Results are presented in three chapters. In Chapter 1, we evaluated whether economic benefits received from the NTFP trade or...

In order to maintain Air Traffic Control (ATC) system safety, security and efficiency, conformance monitoring must be performed to ensure that aircraft adhere to their assigned clearances. New Decision Support Tools (DSTs), coupled to advanced communication, navigation and surveillance technologies are being developed which may enable more effective conformance monitoring to be undertaken relative to today. However, there are currently no general analysis techniques to help identify fundamental conformance monitoring issues and more effective approaches that new DSTs should employ. An approach to address this need is presented in this work that draws parallels between ATC conformance monitoring and general system fault detection, allowing fault detection methods developed for other domains to be employed for this new application. The resulting Conformance Monitoring Analysis Framework provides a structure to research conformance monitoring issues and approaches. Detailed discussions are presented for each of the elements of the framework, including the Conformance Basis, Actual System Representation, Conformance Monitoring Model, Conformance Residual Generation and Decision-Making components. Flight test data during a simple lateral non-conformance maneuver was used to demonstrate various implementation options of the framework. Application of the framework for ATC conformance monitoring research was demonstrated using flight test and simulator data in various operational and surveillance environments. Key findings in the lateral...

Devido a grande importância industrial da união soldada e sendo a soldagem um processo especial de fabricação, que não pode ser completamente inspecionado contra defeitos apenas após sua finalização, o seu monitoramento constante se faz necessário. Pela ISO 3834, o fabricante deve adotar medidas para garantir a qualidade necessária, onde o monitoramento pode ser usado para garantir documentação do processo, auditorias, ações corretivas e revisão de pessoal. Assim, dada importância deste monitoramento, é fundamental ter à disposição da indústria um sistema de utilização direta, mas que contenha o estado da arte em tecnologia de comunicação. Tecnologicamente, o monitoramento é requerido pela ISO 17662:2005, que, além da correta calibração dos sistemas e dos equipamentos, esta norma requer a verificação, ou seja, o registro para confirmação através da provisão de evidência objetiva que as exigências específicas foram cumpridas. É possível encontrar sistemas que consigam realizar tal monitoramento de forma satisfatória, mas com uso de comunicação por cabos, que por muitas dificultam a utilização, e com a necessidade de um computador com sistema operacional específico e que fique solidário ao sistema de monitoramento. Desta forma...

The greenhouse gas effect and the global warning phenomenon are largely discussed by scientific community and government and, in the next years, a number of actions focused on the reduction of the greenhouse gases emissions have to be finalised. The reduction of greenhouse gas emissions can be achieved in several ways but probably, at the short/mid-term, the only way with an acceptable cost/benefit ratio is to avoid the CO2 emission from the fossil fuel power plant and, in parallel, strongly develop the renewable energies. A really interesting option for the reduction of CO2 emissions is CCS (CO2 capture and storage). This technique consists of capturing CO2 from power and industrial activities and storing it in deep geological reservoirs having different geological traps. The potential effectiveness of CCS is the reduction of 15% of the emission by 2050. A critical component of long term geological sequestration of anthropogenic CO2 will be our ability to adequately monitor a chosen site to ensure public and environmental safety. Near surface monitoring is particularly important, as it is possible to conduct sensitive and direct measurements at the boundary between the subsurface and the biosphere (i.e. surface water or atmosphere). In this work different aspects of direct gas measurements for the control and monitoring of CO2 storage sites were undertaken. In particular: i. the study of some fault systems at the Latera caldera allowed a better understanding of the gas migration mechanisms; ii. soil gas surveys carried out at “Concessione mineraria Monte Sinni” and at Kaniow allowed baseline characterization and the test of this approach for the discontinuous post injection monitoring; iii. the design and development of an innovative and low cost monitoring system that can make possible the use of direct geochemical methods of measurement where the currently required costs make them unsuitable. The obtained results seem to confirm the potent of the geochemical approach...

The objective of this assignment was to develop a Monitoring and Evaluation (M&E) system for watershed management in the Loess Plateau area. The M&E system for the China Watershed Management Project (CWMP) has been developed on the base of the M&E system that has been implemented during the previous two phases of the World Bank Loess Plateau Project. The final report presents the main outcomes of this process. The major findings of the M&E systems review are summarized in the following chapter two. The steps of developing and agreeing the M&E framework are presented in chapter three. Chapter four will describe the specific features of and challenges for watershed M&E before chapter five goes into a detailed presentation of the M&E framework. The M&E framework is most significant outcome of this assignment because it brings together all the agreements and considerations around institutional and methodological issues of M&E. The key parameters for M&E are defined in the framework, but they are further specified into operational steps in the M&E guidelines which are prepared as a separate document.

This study investigated the effects of self-monitoring on the homework completion and accuracy rates of four, fourth-grade students with disabilities in an inclusive general education classroom. A multiple baseline across subjects design was utilized to examine four dependent variables: completion of spelling homework, accuracy of spelling homework, completion of math homework, accuracy of math homework. Data were collected and analyzed during baseline, three phases of intervention, and maintenance. Throughout baseline and all phases, participants followed typical classroom procedures, brought their homework to school each day and gave it to the general education teacher. During Phase I of the intervention, participants self-monitored with a daily sheet at home and on the computer at school in the morning using KidTools (Fitzgerald & Koury, 2003); a student friendly, self-monitoring program. They also participated in brief daily conferences to review their self-monitoring sheets with the investigator, their special education teacher. Phase II followed the same steps except conferencing was reduced to two days a week, which were randomly selected by the researcher and Phase III conferencing was one random day a week. Maintenance data were taken over a two-to-three week period subsequent to the end of the intervention. Results of this study demonstrated self-monitoring substantially improved spelling and math homework completion and accuracy rates of students with disabilities in an inclusive...

Since the late 1980s, mining agreements in Papua New Guinea contain a clause that says or implies that there should be something called social monitoring carried out around the mine site. This tends to be an addendum to the much more comprehensive environmental monitoring requirements. There is also a (somewhat reluctant) recognition within the industry that some form of social monitoring is ‘best practice’. In this paper I begin with my vision of where social monitoring in New Guinea is in terms of ‘best practice’. Two developments in social monitoring apparent over the last seven years are then discussed: greater community control over the monitoring programmes, and the apparent loss of interest in social monitoring by all parties involved, but primarily by the sponsors, the companies. I conclude with some possible reasons why there is effectively no social monitoring currently being carried out in the industry in New Guinea, and provide some thoughts on future directions.; no

Effective biodiversity monitoring is critical to evaluate, learn from, and ultimately improve conservation practice. Well conceived, designed and implemented monitoring of biodiversity should:(i) deliver information on trends in key aspects of biodiversity (e.g. population changes); (ii) provide early warning of problems that might otherwise be difficult or expensive to reverse; (iii) generate quantifiable evidence of conservation successes (e.g. species recovery following management) and conservation failures; (iv) highlight ways to make management more effective; and (v) provide information on return on conservation investment. The importance of effective biodiversity monitoring is widely recognized (e.g. Australian Biodiversity Strategy).Yet, while everyone thinks biodiversity monitoring is a good idea, this has not translated into a culture of sound biodiversity monitoring, or widespread use of monitoring data.We identify four barriers to more effective biodiversity monitoring in Australia. These are: (i) many conservation programmes have poorly articulated or vague objectives against which it is difficult to measure progress contributing to design and implementation problems; (ii) the case for long-term and sustained biodiversity monitoring is often poorly developed and/or articulated; (iii) there is often a lack of appropriate institutional support...

Background: It has been hypothesized that internal tocodynamometry, as compared with external monitoring, may provide a more accurate assessment of contractions and thus improve the ability to adjust the dose of oxytocin effectively, resulting in fewer operative deliveries and less fetal distress. However, few data are available to test this hypothesis. Methods: We performed a randomized, controlled trial in six hospitals in the Netherlands to compare internal tocodynamometry with external monitoring of uterine activity in women for whom induced or augmented labor was required. The primary outcome was the rate of operative deliveries, including both cesarean sections and instrumented vaginal deliveries. Secondary outcomes included the use of antibiotics during labor, time from randomization to delivery, and adverse neonatal outcomes (defined as any of the following: an Apgar score at 5 minutes of less than 7, umbilical-artery pH of less than 7.05, and neonatal hospital stay of longer than 48 hours). Results: We randomly assigned 1456 women to either internal tocodynamometry (734) or external monitoring (722). The operative-delivery rate was 31.3% in the internal-tocodynamometry group and 29.6% in the external-monitoring group (relative risk with internal monitoring...

BACKGROUND: The use of cardiac output monitoring may improve patient outcomes after major surgery. However, little is known about the use of this technology across nations. METHODS: This is a secondary analysis of a previously published observational study. Patients aged 16 years and over undergoing major non-cardiac surgery in a 7-day period in April 2011 were included into this analysis. The objective is to describe prevalence and type of cardiac output monitoring used in major surgery in Europe. RESULTS: Included in the analysis were 12,170 patients from the surgical services of 426 hospitals in 28 European nations. One thousand four hundred and sixteen patients (11.6 %) were exposed to cardiac output monitoring, and 2343 patients (19.3 %) received a central venous catheter. Patients with higher American Society of Anesthesiologists (ASA) scores were more frequently exposed to cardiac output monitoring (ASA I and II, 643 patients [8.6 %]; ASA III-V, 768 patients [16.2 %]; p < 0.01) and central venous catheter (ASA I and II, 874 patients [11.8 %]; ASA III-V, 1463 patients [30.9 %]; p < 0.01). In elective surgery, 990 patients (10.8 %) were exposed to cardiac output monitoring, in urgent surgery 252 patients (11.7 %) and in emergency surgery 173 patients (19.8 %). A central venous catheter was used in 1514 patients (16.6 %) undergoing elective...

The widespread adoption of cloud computing makes cloud services a core component of modern IT systems. Cloud service monitoring brings benefits to both service providers and consumers. It enables customers to track the status and quality of their services to ensure that their SLAs are satisfied and possibly record any SLA violations. It also supports service providers to predict potential violations and deploy additional resources in advance to avoid possible penalties of performance violations. However, federated cloud poses challenges to application monitoring due to the lack of cross-platform interoperability, management, and vendor lock-in constraints. In addition, SLA definitions might be different from one service provider to another. Many cloud providers offer tools to enable customers to monitor the performance of their cloud-based services. The major drawback of these commercial monitoring tools is that they do not present enough detail to consumers to be able to customize the behavior of these tools to accommodate their specific requirements. In addition, such monitoring tools typically are provider-dependent, which means that consumers cannot use the same monitoring platform for multiple cloud providers. In this thesis...

We report on the design and implementation of ecological monitoring for an Australian biodiversity conservation incentive scheme - the Environmental Stewardship Program. The Program uses competitive auctions to contract individual land managers for up to 15 years to conserve matters of National Environmental Significance (with an initial priority on nationally threatened ecological communities). The ecological monitoring was explicitly aligned with the Program's policy objective and desired outcomes and was applied to the Program's initial Project which targeted the critically endangered White Box-Yellow Box-Blakely's Red Gum Grassy Woodland and Derived Native Grassland ecological community in south eastern Australia. These woodlands have been reduced to <3% of their original extent and persist mostly as small remnants of variable condition on private farmland. We established monitoring sites on 153 farms located over 172,232 sq km. On each farm we established a monitoring site within the woodland patch funded for management and, wherever possible, a matched control site. The monitoring has entailed gathering data on vegetation condition, reptiles and birds. We also gathered data on the costs of experimental design, site establishment...

Background: The goals for the management of COPD are to delay the process of disease progression and alleviate its manifestations. The follow-up of the patients' physical and mental condition is part of best practice management when monitoring routines results in information that contributes to the achievement of management goals. However, the recommendations on monitoring procedures may differ between guidelines and may not be based on scientific evidence. The aim of this article is to review the current guideline recommendations on monitoring routines for COPD. Methods: Clinical practice guidelines on the management of COPD were identified by a Medline search, Internet search and expanded by experts in the respiratory field. Guidelines on the management of COPD were analysed on recommended monitoring routines, recommended frequency of monitoring. Results: Eighteen clinical practice guidelines on the management of COPD were analysed. The follow-up of lung function indices was the most frequently recommended monitoring routine. Moreover, monitoring of symptoms, exercise tolerance, comorbidity, and smoking habits were recommended regularly. In none of the guidelines, the recommended monitoring routines were evidence based. Only one guideline provides a different set of monitoring parameters for advanced COPD compared to mild and moderate COPD. Conclusion: Some monitoring routines were recommended frequently...

Acoustic recording of echolocation activity of bats is a means of monitoring bat activity or habitat use over time and space. Advances in technology permit long-term monitoring of echolocation activity relatively cheaply and there is much interest in developing acoustic monitoring protocols for long-term monitoring of bat populations. There are many challenges to using acoustic recordings for monitoring underlying changes in bat populations, but acoustic recordings can be used to evaluate changes in use and activity. There has been much recent attention and effort to develop automated species identification/classification and to make these tools available through both commercial software or free online. More work needs to be done, however, before automated species classification can be implemented for monitoring bats on continental or global scales. Here, I provide a brief overview of current popular systems for long-term echolocation monitoring and discuss some of the challenges and advantages of current acoustic monitoring systems.
