"Tempo de tratamento da tuberculose de pacientes inscritos em um serviço de saúde do município de Ribeirão Preto - SP (1998-1999)" / Time of tuberculosis treatment in patients enrolled in a health service in the city of Ribeirão Preto-SP (1998-1999)

Cinthia Midori Sassaki 07 February 2003 (has links)
Trata-se de um estudo epidemiológico descritivo que busca analisar o tempo de tratamento da tuberculose de pacientes inscritos no Programa de Controle da Tuberculose de um serviço de saúde do município de Ribeirão Preto-SP, no período de janeiro de 1998 a dezembro de 1999. Os dados relativos a algumas variáveis sociodemográficas (sexo, idade, escolaridade e ocupação), ao diagnóstico (forma clínica), ao tratamento (condição, esquema, tipo, tempo e resultado de tratamento), a intercorrências "patológicas" e a doenças associadas (AIDS e alcoolismo) foram obtidos através de livros de registro e de prontuários. Utilizou-se o programa Epi-Info, versão 6.04d para o cadastramento, tabulação e análise dos dados. Observou-se que dos 140 pacientes em estudo, 105 (75%) pacientes curaram, 20 (14,29%) foram transferidos, 05 (3,57%) tiveram mudança de diagnóstico, 05 (3,57%) abandonaram e 05 (3,57%) foram a óbito. Em relação à cura, 39,05% curaram em até 6 meses; 39,05% entre 6,1 e 9 meses; 20% em mais de 9 meses e 1,9% foi ignorado. Identificou-se que a história de tratamento anterior, intercorrências patológicas, AIDS e alcoolismo contribuíram para o não-cumprimento correto da terapêutica, prolongando o tempo de tratamento entre os indivíduos curados. Quanto ao tempo de tratamento dos pacientes que não evoluíram para a cura, 09 (25,71%) não curaram após 6 meses de tratamento (03 abandonos; 03 óbitos; 02 mudanças de diagnóstico e 01 transferência). Pode-se verificar que as intercorrências podem acontecer ao longo do tratamento, ocasionando desvios como o não-cumprimento do esquema terapêutico, aumentando o tempo de tratamento, o risco de abandono e até mesmo o óbito. Além disso, o estudo possibilitou descrever o tempo de tratamento da tuberculose no Programa (diferença entre data da última e da primeira ingestão do medicamento) e o mês de término do tratamento registrado no prontuário (computado através do número de cartelas de medicamentos concluídos). Verificou-se que o dado registrado no prontuário altera o tempo real de tratamento da tuberculose, uma vez que essa anotação considera como 1 mês de tratamento, a contagem do término de 1 cartela de medicamentos concluída pelo paciente, que pode ter duração de mais de 30 dias. Constatou-se, neste estudo, o preenchimento incompleto das fichas de notificação e das folhas de evolução médica e de enfermagem, bem como o critério de registro correspondente ao mês de tratamento do doente, sugerindo uma maior atenção do serviço para esses fatos e melhor esclarecimento aos trabalhadores de saúde sobre os critérios e a precisão dos dados a serem informados. / This is a descriptive epidemiological study which aims at analyzing tuberculosis treatment in patients enrolled in the Tuberculosis Control Program of a health service in the city of Ribeirão Preto-SP from January 1998 to December 1999. Data concerning some social and demographic variables (sex, age, education and occupation), the diagnosis (clinical condition), treatment (condition, plan, type, period and treatment results), pathological intercurrences and associated diseases (AIDS and alcoholism) were obtained through records books and charts. The Epi-Info, version 6.04d was used for data recording, tabulation and analysis. It was observed that of the 140 patients under study, 105 (75%) patients were cured, 20 (14.29%) were transferred, 05 (3.57%) had their diagnoses changed, 05 (3.57%) quit treatment and 05 (3.57%) passed away. Concerning cure, 39.05% were cured in the period of 6 months; 39.05% in a period of 6.1 to 9 months; 20% in more than 9 months and 1.9% were ignored. It was identified that the history of previous treatment, pathological intercurrences, AIDS and alcoholism contributed to not following therapy adequately, which extended the time of treatment among cured individuals. Concerning the time of treatment of patients who did not develop to cure, 09 (25.71%) were not cured after 6 months of treatment (03 dropouts; 03 deaths; 02 diagnosis alterations and 01 transfer). It can be observed that intercurrences may occur during treatment, which causes deviances such as the non-adherence to the therapeutic plan and increase in the treatment period, risks of quitting and even death. In addition, the study enabled the comparison between the time of treatment of tuberculosis in the Program (difference between the dates of the last and first medication ingestion) and the month of completion of treatment recorded in the chart (calculated through the number of medication packages used). It was observed that the information recorded in the chart changed the real time of tuberculosis treatment, since this note considered as a month of treatment the counting of the consumption of one medication package consumed by the patient, which can take over 30 days. Incomplete report forms, medical and nursing development sheets and the recording criterion corresponding to the patient’s month of treatment were found in this study, which suggests greater attention from the service to these facts and a better clarification to health workers concerning the criteria and precision of the data to be informed.

Utvärdering av svensk vindkraft : Skillnaden mellan skogs- och traditionella placeringar

Lindahl, Andreas January 2009 (has links)
<p>During the last years commercial Wind Power Turbines (WPT) has become larger regardingto the generator sizes and hub heights. Available hub heights around 100 meters is nowcommon, which has led to profitability for WPT located in forests where there normally are tolow wind speeds. The current knowledgement regarding turbulence and the variation in thewind profile for the outcome of the power production for the WPT in forests is limited.In this Master of Science thesis an investigation concerning forest located wind power plantshas been made. The purpose has been to investigate if plants located in forest perform lesscompared to wind power turbines located at more common locations.The analyses are based on statically material for determining the availability,production/generator size, production/hub height, production/swept area and how thetopography affect the production results.The analyses show that the variation in production result for WPT located in forest comparedto turbines located at other locations is small. The availability is high and the productionresults are good.</p>

Artin's Primitive Root Conjecture and its Extension to Compositie Moduli

Camire, Patrice January 2008 (has links)
If we fix an integer a not equal to -1 and which is not a perfect square, we are interested in estimating the quantity N_{a}(x) representing the number of prime integers p up to x such that a is a generator of the cyclic group (Z/pZ)*. We will first show how to obtain an aymptotic formula for N_{a}(x) under the assumption of the generalized Riemann hypothesis. We then investigate the average behaviour of N_{a}(x) and we provide an unconditional result. Finally, we discuss how to generalize the problem over (Z/mZ)*, where m > 0 is not necessarily a prime integer. We present an average result in this setting and prove the existence of oscillation.

Comparison of numerical result checking mechanisms for FFT computations under faults

Bharthipudi, Saraswati 01 January 2004 (has links)
This thesis studies and compares existing Numerical Result checking algorithms for FFT computations under faults. In order to simulate faulty conditions, a fault injection tool is implemented. The fault injection tool is designed so as to be as non-intrusive to the application as possible. Faults are injected into memory in the form of bit flips in the data elements of the application. The performance of the three result checking algorithms under these conditions is studied and compared. Faults are injected at all the stages of the FFT computation by flipping each of the 64-bits in the double-precision representation. Experiments also include introducing random bit flips in the data array, emulating a more real-life like scenario. Finally the performance of these algorithms under a set of worst-case is also studied

Comparing The Business Models Of Chain Coffee Stores¡GThe Resource-Building Mechanism Perspective

Hung, Liang-kun 09 January 2012 (has links)
This research is on the chain coffee store. The case study is formulated by applying ¡§resources-building mechanism¡¨ (Feng-Lee Lin, 2009) to look into the business models adopted by different market players. The goal is to decompose each business model, pinpoint the difference, understand the cause and effect between business models and performances, and, one step forward, to predict the the management result. In the ¡§resources-building mechanism¡¨ theory which defines a firm¡¦s physical-energy-spirit equivalents: physical to a firm¡¦s physical properties, energy to a firm¡¦s driving power, and spirit to a firm¡¦s frame of mind. Physical, energy, spirit are the three essential elements in the making of a resources. Each of the three elements interacts with one another. The resources-building relies on utilizing both a firm¡¦s internal and external resources. The internal and external resources optimization are mutually enhanced, interacted and ultimately merged. From the ¡§Resources-building mechanism¡¨ perspective to explain business model construction mechanism of chain coffee store and take the well-known coffee chain store as the object of study. The conclusions are drawn: 1. The business model of chain coffee stores is the aggregation of the interior ¡§product¡¨ and the exterior ¡§customer¡¨. 2. The business model is composed of service, management state, brand name, target customer, consumption and the market trend. All these factors interact with one another. 3. The performance of the market player is positively correlated with the coordination and conciliation of the above six factors. Therefore, by appraising the degree of conciliation, we can measure the effectiveness of management. 4. Forecast of the chain coffee store case management result: The CITY CAFÉ ranks on top of the list in the evaluation, the manage result will be best among the four companies.85¢J coffee has sound adaptive degree, the manage result will be only inferior to CITY CAFÉ while Starbucks¡¦ (TAIWAN) adaptive degree is ordinary and the manage result will be inferior to CITYCAFÉ and 85¢J. Crown &Fancy CAFÉ¡¦s adaptive degree is bad, the manage result will be the worst among the four.

Visualization for frequent pattern mining

Carmichael, Christopher Lee 03 April 2013 (has links)
Data mining algorithms analyze and mine databases for discovering implicit, previously unknown and potentially useful knowledge. Frequent pattern mining algorithms discover sets of database items that often occur together. Many of the frequent pattern mining algorithms represent the discovered knowledge in the form of a long textual list containing these sets of frequently co-occurring database items. As the amount of discovered knowledge can be large, it may not be easy for most users to examine and understand such a long textual list of knowledge. In my M.Sc. thesis, I represent both the original database and the discovered knowledge in pictorial form. Specifically, I design a new interactive visualization system for viewing the original transaction data (which are then fed into the frequent pattern mining engine) and for revealing the interesting knowledge discovered from the transaction data in the form of mined patterns.
