Chemical Equilibrium misconceptions impaired the learning of many biochemicalundergraduate content. It was widely reinforced by chemical education data. On the otherhand there was no data for the consequences in biochemistry learning. OBJECTIVE Weproposed the construction of an Aminoacid Paper Electrophoresis software as a tool forChemical Equilibrium teaching and learning which aims to integrate the representationallevels, being macroscopic, microscopic and symbolic in a way to evidence to student thedynamic character of the equilibrium phenomena. It attenuates misconceptions andreduces impairments on biochemistry learning. Although the simulator is based onclassical biochemistry topic it is designed to deal with chemical equilibrium concepts in thecontext of biochemistry. MATERIALS AND METHODS: The software is an PaperElectrophoresis Simulator programmed in HTML5 language. It guides the student stepstoward the simulation showing the technique fundamentals and variables allowing tochoose aminoacids in a list, as well as build even tetrapeptides and run even four samplesin a single simulation after what is defined a pH for simulation. The simulation results areshown in a depiction of a paper electrophoresis device (macroscopic) the speciesproportion in the medium based on the Handerson-Hasselbalch formula (symbolic) and thespecies charge change based on the medium pH (microscopic). All activities are guided bya task list based on previous diagnostic on chemical equilibrium misconceptions.RESULTS AND DISCUSSION: Results were based on observation of students classdiscussion and survey. Many of previously diagnosed misconceptions were attenuated intests of chemical equilibrium falling from a 72% to 35% error average; and a studentssurvey agreed with simulator objectives (90%), ease of use (94%), chemicalrepresentations straightness (82%), simulation results (71%) integration ofrepresentational levels (87%). CONCLUSIONS: Students declared the software usabilityand reduced its misconceptions on chemical equilibrium.

O fato de os artigos deste período estarem todos disponíveis em meio eletrônico facilita a realização de estudos que lancem mão dessa massa de dados eletrônica na obtenção de subsídios para análise. Este artigo apresenta os achados de uma pesquisa quantitativa que consistiu no tratamento dos dados contidos nas 9.289 referências, dos 339 artigos aceitos pela área de ADI do Enanpad, de 1997 a 2006. Dentre os resultados mais significativos está o mapeamento das principais fontes das idéias que fundamentam os trabalhos dos pesquisadores brasileiros da área, identificando-se países, instituições, periódicos, editoras, eventos científicos e autores que os inspiram. After 10 years of digital proceedings for Enanpad (the largest academic business conference in Brazil), this would seem to be a good time to evaluate how its Information Management field is performing. The fact that all papers published in the proceedings during this period of time are available in electronic media makes it easy for studies to be carried out that use that huge amount of available electronic data. This paper presents the findings of a quantitative study that involved handling the data contained in 9.289 references included in the 339 papers published in the proceedings of the Information Management field in Enanpad, from 1997 to 2006. Amongst the most significant results is the identification of the authors, universities, journals, publishers and scientific events that inspire researchers in the IS field in Brazil.

Chromatography is a method used for analyses of mixture components based on different criteria: adsorbility, solubility, molecular mass, ionic charge and affinity. It is an important subject of Biochemistry. This work reports the development and the validation of a software that simulated a laboratory activity named Ascendant Chromatography on Paper of Aminoacids. The organization and the multimedia material collection were done during the 2008/2 semester. The most representative images were inserted into the learning object. The tool used for the software development was Adobe® Flash® CS3. The first application of this object was in Biochemistry I (Pharmacy-UFRGS) in 2009/1. Using this experience, a new version was developed which was tested by the students of the same subject in 2009/2. After a 50-minute class (theoretical-practical), the students of both semesters were divided in two groups. Group I answered a questionnaire about chromatography basic concepts and after used the software. Group II was submitted to an inverse protocol. The groups also evaluated the technical aspects of the software animation/simulation and the activity carried out. Associating both applications results (2009/1 and 2009/2), the present learning object can be valid as a support for practical teaching of basic biochemistry.

A utilização da fotografia digital em Ortodontia tem sido assunto de grande interesse nos últimos anos. Este novo recurso possui inúmeras características que o torna um método de obtenção de imagens muito interessante. Por outro lado, a dúvida quanto à qualidade das imagens gerada por esses novos equipamentos, muitas vezes, desencoraja os profissionais a utilizarem essa nova tecnologia. O objetivo desse trabalho foi avaliar a capacidade de percepção dos ortodontistas em diferenciar as fotografias analógicas das digitais, bem como pesquisar a qualidade das mesmas. Para essa avaliação, foram selecionadas dez fotografias digitais e dez analógicas com um padrão ótimo de qualidade. Todas as tomadas fotográficas foram realizadas pelo mesmo operador. As imagens foram "reveladas" em papel fotográfico e submetidas à avaliação de cinco ortodontistas e cinco alunos de pós-graduação em Ortodontia sorteados aleatoriamente. Os examinadores definiram se as fotografias foram obtidas por câmeras fotográficas analógicas ou digitais e julgaram a qualidade de cada fotografia em uma escala que variava de zero a cinco. Os dados obtidos foram submetidos ao tratamento estatístico e os resultados encontrados demonstraram que a freqüência de erros e acertos ocorreu igualmente nos dois tipos de fotografias (p > 0,05). Em relação à qualidade das fotografias analisadas, o valor médio conferido pelos examinadores às fotografias analógicas foi de 3,49 e o das digitais foi de 4,07 (p < 0,001). Conclui-se que a qualidade da fotografia digital encontra-se dentro de padrões plenamente aplicáveis à Ortodontia. The interest in applying digital photography in orthodontics has increased significantly in recent years. This system presents some properties that make it an interesting alternative to the traditional analogic cameras routinely used in the orthodontic field. However, a number of professionals still question if the digital images quality is comparable to that obtained with analogic photos. Therefore, some orthodontists have not incorporated digital photography to acquire clinical images in their offices. The purpose of this study was to compare the quality of digital and analogical orthodontic photographs and evaluate the ability of the clinicians to differentiate between both types of images. The sample consisted of twenty photographs (ten digital and ten analogical) that followed the American Board of Orthodontists standards. All pictures were taken by the same operator. They were printed in professional photographic paper and submited for evaluation by 5 Orthodontics` professors and an equal amount of orthodontic residents. The evaluators were asked to determine if the images were obtained by digital or analogical cameras, and to grade the quality of each photograph in a zero to five scale. The data recorded was submitted to statistical tests and the results showed no significant diferences in the frequency of errors in ideintifying both types of photographs (p > 0,05). The mean quality value for digital photos was 4.07 and 3.49 for analogic images (p < 0,001). The results of this study indicate that the quality of digital photography is within the standards required for their application to clinical orthodontics.

Nesta breve nota, visamos a introdução de alguns conceitos e operações importantes sobre a aplicações das teorias da percolação e da renormalização ao estudo de meios porosos.
