Cómo leer y generar publicaciones científicas: exploración gráfica de datos cuantitativos: la importancia de mirar la información / How to read and generate scientific publications: in this issue: graphical exploration of quantitative data: the importance of looking at the information

Once the collection of data from a study has been completed and the respective database is available, the researcher is often impatient to answer the research question and ventures into the final steps of the analysis. However, a key stage, prior to a more complex or sophisticated statistical analysis, is data exploration and descriptive statistics. Unfortunately, the exploratory analysis of the data is often performed without much dedication, or is simply "skipped", which can have important consequences on the results obtained and lead to the report of erroneous conclusions. On the one hand, exploration allows to detect errors in the data and, if possible, to correct them from the source of origin or take them into account to make decisions about what to do with them. On the other hand, exploration allows to know the behavior of the variables evaluated in terms of their distribution (key concept in Statistics) and possible relationships among them, which is essential for subsequent descriptive and inferential analysis. The objective of this article is to show graphic tools for the exploration of quantitative data, in order to visualize its distribution and compare groups according to categories of qualitative variables.

Una vez finalizada la recolección de datos de un estudio y contado con la respectiva base de datos, es frecuente que el investigador esté impaciente por responder a la pregunta de investigación y se aventure a realizar los pasos finales del análisis. No obstante, una etapa clave, previa a un análisis estadístico más complejo o sofisticado, es la exploración de datos y la estadística descriptiva. Lamentablemente, el análisis exploratorio de los datos muchas veces es realizado sin mucha dedicación, o simplemente es "saltado", lo que puede tener consecuencias importantes en los resultados obtenidos y conducir al reporte de conclusiones erróneas. Por un lado, la exploración permite detectar errores en los datos y, si es posible, corregirlos desde la fuente de origen o tenerlos en cuenta para tomar decisiones respecto a qué hacer con ellos. Por otra parte, la exploración permite conocer el comportamiento de las variables evaluadas en términos de su distribución (concepto clave en Estadística) y posibles relaciones entre ellas, lo cual es fundamental para los análisis descriptivo e inferencial posteriores. El objetivo de este artículo es mostrar herramientas gráficas para la exploración de datos cuantitativos, con el fin de visualizar su distribución y comparar grupos según categorías de variables cualitativas.

Desenvolvimento de um protótipo de software para quantificar a gordura epicárdica em imagens de tomografia computadorizada / Development of a software prototype to quantify the epicardial fat in computer tomography images

JUSTIFICATIVA E OBJETIVO: A obesidade é um dos maiores e principais fatores de risco para doenças cardiovasculares. A gordura epicárdica é encontrada em torno das artérias coronárias e do miocárdio. O objetivo deste trabalho foi apresentar um protótipo de software capaz de quantificar a gordura em imagens de tomografia computadorizada. Foram encontrados estudos sobre o assunto, porém todos necessitam da interação do usuário. Os resultados foram avaliados positivamente por um cardiologista, que, hoje, delimita manualmente essa membrana. A gordura localizada em torno do coração contribui diretamente para a obstrução das artérias. MÉTODOS: Estudo retrospectivo, no qual os pacientes receberam aproximadamente 20mg de metoprolol endovenoso, para controle da frequência cardíaca (faixa de 70bpm), e 5mg de dinitrato de isossorbida sublingual, para dilatação e melhor visualização das artérias coronárias. As mesmas imagens foram submetidas a três operadores, sendo um deles cardiologista, para que detectassem, de forma manual, a gordura nas imagens. O comparativo entre o sistema manual e automático foi realizado usando o RUMA, para identificar a validade do experimento automático. RESULTADO: O protótipo obteve um percentual médio de 91% de acerto das imagens analisadas. Esse percentual correspondeu à área de gordura encontrada de maneira automática em comparação àquela encontrada por intermédio do processo manual. CONCLUSÃO: As reais possibilidades de automatização de processos maçantes na área médica reforçam os resultados positivos obtidos por este trabalho. O sistema deve garantir ao cardiologista ou operador um tempo mais longo, a ser utilizado em trabalhos que exijam análise e delineamento do problema...

BACKGROUND AND OBJECTIVE: Obesity is one of the highest and major risk factors among those for cardiovascular diseases. The epicardial fat remains around the coronary arteries and myocardium. The objective of this work was to develope a prototype to quantify the epicardial fat in tomography images. We have found studies that address the topic, but in all of them the user interaction is necessary. The results were evaluated by a cardiologist with extensive experience. The fat localized around the heart directly contributes to bad prognosis. The aim of this study was to develop a prototype for the automatic detection of epicardial fat in computed tomography images. METHODS: Retrospective study, in which patients received around 20mg of intravenous metoprolol, for heart rate control (70bpm), and 5mg sublingual isosorbide dinitrate, to dilation and better visualization of the coronary arteries. These images were processed by one cardiologist and by two lay operators, to detect the fat manually. The RUMA method was used to validate the automatic process. RESULTS: The prototype achieved an average percentage of 91% correct images analyzed. This percentage corresponded to the area of fat found in an automatic way compared to that found by manual process. CONCLUSION: The real possibilities of automation of tiresome processes in the medical reinforce the positive results obtained in this work. This system must ensure a greater portion of time, that can be used in analysis that require a more critical thinking...

Aproximação fisionômica pericial através de função de base radial hermitiana / Forensic facial approximation through hermitian radial basis functions

A aproximação fisionômica é o método que busca, a partir do crânio, simular a fotografia de um indivíduo quando em vida. Deve ser empregada como último recurso, na busca de desaparecidos, quando não houver possibilidade de aplicação de um método válido de identificação. O objetivo deste estudo foi obter a aproximação fisionômica, a partir de um crânio seco e de tomografia computadorizada multislice de indivíduos vivos, através da função de base radial hermitiana (FBRH). Constituiu-se também em avaliar o resultado da mesma quanto ao reconhecimento. Na primeira etapa do estudo, foi utilizada a imagem escaneada de um crânio seco, de origem desconhecida, com o intuito de avaliar se a quantidade de pontos obtidos seria suficiente para aplicação da FBRH e consequente reconstrução da superfície facial. Na segunda fase, foram utilizadas três tomografias de indivíduos vivos, para análise da semelhança alcançada entre a face escaneada e as aproximações faciais. Nesta etapa, foi aplicada uma associação de diferentes metodologias já publicadas, para reconstrução de uma mesma região da face, a partir de um mesmo crânio. Na última etapa, foram simuladas situações de reconhecimento com familiares e amigos dos indivíduos doadores das tomografias. Observou-se que a metodologia de FBRH pode ser empregada em aproximação fisionômica. Houve reconhecimento positivo nos três sujeitos estudados, sendo que, em dois deles, os resultados foram ainda mais significativos. Desta forma, conclui-se que a metodologia é rápida, objetiva e proporciona o reconhecimento. Esta permite a criação de múltiplas versões de aproximações fisionômicas a partir do mesmo crânio, o que amplia as possibilidades de reconhecimento. Observou-se ainda que a técnica não exige habilidade artística do profissional...

Facial approximation works by building the visual face up from the skull. This method should be performed as last resort, to carry out for missing persons, when there is no other primary identification method avaliable. The purpose of this study was to introduce a new computerized method with hermite radial basis function (HRBF) for facial approximation using dry skull and computed tomography (CT). The same was also evaluated as a result of the recognition. Firstly, a scan of a dry unidentified skull image was used in order to assess if the amount of points would be sufficient for HRBF methodology and subsequent reconstruction of the facial surface. In second, three CT scans of living individuals were used to evaluate the similarity achieved between the real face scanned and facial approximations. An association of different facial structures reconstruction techniques already published for the same region of the face was applied for the same skull. Moreover, some situations from developed facial approximations were simulated, as recognition by a relative or parent, on a face pool-test. Results from the study showed that the purposed methodology can be used for facial approximation. At the three cases a correct approximation identification as one of a few possible matches to the missing person happened. In two of them, the results were consistently better at identifying the correct approximation. In conclusion, the proposed methodology is fast, objective and reaches visual identification. It is possible to perform multiple versions of the same skull, changing the selected data into the system, which maximizes the chances of establishing recognition of the target face. It was also observed that the technique does not need artistic interpretation...

The Development of a Graphical User Interface Engine for the Convenient Use of the HL7 Version 2.x Interface Engine / 대한의료정보학회지

OBJECTIVES: The Health Level Seven Interface Engine (HL7 IE), developed by Kyungpook National University, has been employed in health information systems, however users without a background in programming have reported difficulties in using it. Therefore, we developed a graphical user interface (GUI) engine to make the use of the HL7 IE more convenient. METHODS: The GUI engine was directly connected with the HL7 IE to handle the HL7 version 2.x messages. Furthermore, the information exchange rules (called the mapping data), represented by a conceptual graph in the GUI engine, were transformed into program objects that were made available to the HL7 IE; the mapping data were stored as binary files for reuse. The usefulness of the GUI engine was examined through information exchange tests between an HL7 version 2.x message and a health information database system. RESULTS: Users could easily create HL7 version 2.x messages by creating a conceptual graph through the GUI engine without requiring assistance from programmers. In addition, time could be saved when creating new information exchange rules by reusing the stored mapping data. CONCLUSIONS: The GUI engine was not able to incorporate information types (e.g., extensible markup language, XML) other than the HL7 version 2.x messages and the database, because it was designed exclusively for the HL7 IE protocol. However, in future work, by including additional parsers to manage XML-based information such as Continuity of Care Documents (CCD) and Continuity of Care Records (CCR), we plan to ensure that the GUI engine will be more widely accessible for the health field.

The Use of Graphic Monitoring during Mechanical Ventilation

Graphic monitoring assists the clinician at the bedside in several ways. It can be helpful in fine-tuning or adjusting ventilator parameters. Graphic monitoring may help to determine the patient's response to pharmacologic agents. The clinician also has the ability to trend monitored events over a prolonged period of time. The neonatal patient's self respiration, synchrony to ventilator and respiratory efforts can be well recognized with graphic monitoring. Of all, it may enable detection of complications before they become clinically apparent. This article introduces the basics of real-time graphics.

Análise espacial e temporal da incidência da malária em três comunidades no Pará, no período de 2001 a 2006. / Spatial and temporal analysis of malaria incidence in three communities in Pará, Brazil, between 2001 and 2006.

Considerando a necessidade de gerar análises da relação entre os dados ambientais e epidemiológicos que caracterizaram a incidência da malária nos municípios de Bragança, nas comunidades do Acarajó e Fazendinha e Augusto Corrêa, na comunidade do Treme, todas no estado do Pará, no período de 2001 a 2006, foi desenvolvido um modelo que integrou diversas geotecnologias emergentes. Para tal, foi utilizada a geoindexação de informações temáticas geradas em trabalhos de campo e laboratoriais, além de tecnologias de geoprocessamento, estatística e banco de dados epidemiológicos. Os resultados das análises foram expressos em bases cartográficas digitais. Para a realização da predição de risco de transmissão foi desenvolvido um módulo Fuzzy, com as características ambientais e socioeconômicas das áreas de estudo, em função das quais foi identificado um alto risco de transmissão pela doença, devido a práticas de desflorestamento e ocupação humana, nestes locais. Levando em consideração os resultados obtidos com a implementação do modelo, o mesmo foi considerado de grande potencial para análises ecoepidemiológicas de malária, em face dos objetivos preconizados.

Considering the need to analyze the relation between environmental and epidemiological data to characterize malaria incidence in Acarajó and Fazendinha communities, located in Bragança district, and also in Treme community, in Augusto Correa district, in the state of Pará, Brazil, between 2001 and 2006, an analysis model that integrated several emerging geotechnologies was developed. The proposed analysis used thematic information generated on laboratory and works, and also geoprocessing, epidemiological databases and statistical technologies. The results of the analysis were expressed on digital maps. In order to predict the transmissionrisk it was developed a fuzzy model with social, economic and environmental characteristics o f the study areas, that enabled the identification of high risk of disease transmission, due to deforestation and human occupation, in those areas. Considering the results obtained, the model was considered with great potential for eco-epidemiological analysis of malaria.

MATERIALS AND METHOD:Two hundred and forty seven ventilation tubes were classified according to shape, size and material. Experimental design of a ventilation tube was performed with various graphic modellings. RESULTS: Grommet style was most common and most of flanges showed round type. Polymer has been a material of choice in making ventilation tubes. Length of the shaft ranged 1.5mm-15mm. Four kinds of models were created for designing a ventilation tube using computer graphics. CONCLUSION: Biofunctionality should be taken into account in designing ventilation tubes.

Basic concepts of computer simulation of plant growth.

The experimental study of plant growth and architecture requires two consecutive and complementary approaches. The first one is qualitative and botanical. Through this qualitative analysis, it is possible to divide a tree into botanically homogeneous subunits. The second one is quantitative. Modeling of the functioning of meristems based on stochastic processes has been carried out in the Laboratoire de Modelisation of CIRAD (1980 1990) in combination with extensive experimental work on temperate and tropical plants. Calculations involved in the tree simulations from field data are based on the probabilistic Monte Carlo method for the topological part and on analytical geometry for the morphological part. Data, such as length, angles, elasticities, tropism, are necessary for geometric construction of the plant. The growth model, together with the geometric calculations enables a random plant simulation in 3-D according to geometry for the morphological one. Computer graphics methods are then used to visualize the computed plant (perspective, colours, texture, shadows); they require special programs and graphic computers.

THREE DIMENSIONAL RECONSTRUCTION OF THIGH MUSCLE GROUPS BY COMPUTER GRAPHICS / 体力科学

The purpose of this study is to develop the non-invesive method for three dimensional analysis of knee extensor and knee flexor muscle groups of the thigh part in human subjects. Our system consisted of magnetic resonance imaging (MRI) to get cross-sectional images of muscle and a computer graphics system which reconstructs three dimensional image of each muscle. The subjects chosen for this study were four healthy male adults, aged from 21 to 30 years. MRI scan was carried out from head of the femur to the upper border of the patella along thigh. Three dimensional (3D) muscular image was reconstructed based on the data from MRI. Referring to the anatomic feature, contour information of knee extensor muscles (KEM) and knee flexor muscles (KFM) was identified on MRI and those muscles were reconstructed to 3 D images using the computer graphics system. This system also provided information on the quantitative volume and cross-sectional area (CSA) of each muscle.<BR>The structure of each muscle of KEM and KFM was displayed by a wireframe model or a surface model on the CRT. It was revealed that 3D muscular images of the surface model using coloring and shadowing were highly effective to understand their shapes and relative location of muscles. CSA and volume of KEM were 86.84±8.38cm<SUP>2</SUP>and 2044.25±168.28cm<SUP>3</SUP> and those of KFM were 38.48±5.90cm<SUP>2</SUP> and 751.95±50.56cm<SUP>3</SUP> respectively.<BR>These results indicate that not only the anatomical information but also the volume and maximum CSAs of KEM and KFM can be measured quantitatively by this method using three dimensional analysis.

Objective To propose an improved C-means segment method based on Gibbs random field accelerated by GPU.Methods The parallel computation of pixel shades was used to take the place of the classical point-by-point method of CPU.By this way,the efficiency was higher than merely using the CPU computation.Results The efficiency of computation was improved over 400%.The load of CPU was reduced and the effect of accelerator was obvious.Conclusion The improved C-means segment method based on Gibbs random field accelerated by GPU enhances the clinical application of image segmentation,the computer rate of which is improved distinctly and closely to real time.[Chinese Medical Equipment Journal,2008,29(2):6-9]

Drug protein interaction at the molecular level: A study of sulphonamide carbonic anhydrase complexes.

The molecular mechanism of drug action has been studied by X-ray diffraction analysis of human carbonic anhydrase I complexed with two different sulphonamides. The acetazolamide and amino benzene sulphonamide are found to bind to the catalytically essential zinc ion thereby inhibiting the function of the enzyme. The inhibitor molecules are stabilized in the active site of the protein by van der Waals interaction with a number of protein side chain groups.
