O (des)conhecimento do professor sobre a avaliação e o plano de desenvolvimento da escola

This paper is part of an extension project titled “The implementation of the School Development Plan in public schools of São Paulo: contradictions and implications for the educational management practice”. The School Development Plan is a program supported by the Ministry of Education through the National Fund for Education Development. Since 2010, it has been directed to state and local public schools that have not reached the goals set by the Basic Education Development Index. This research has been conducted in four public schools of an inner city of São Paulo since April 2011, in which the School Development Plan is being implemented. The objective of this study is to analyze the teachers’ concepts of learning assessment and identify the instruments used for such assessment and when they are used. The research made use of a qualitative approach. The study is based on literature review and data collected through questionnaires completed by teachers. We consider the importance of teachers monitoring the whole teaching and learning process and not only the results. However, public policies stimulate final results; thus, the study points out that teachers perform a checking, not an assessment, since there is no decision making. It is crucial to join quantity and quality when performing an assessment that diagnoses and values students and their effective learning.

Avaliação sensorial de adolescentes com desenvolvimento normal na faixa etária de 11 a 18 anos

Tactile sensibility allows for adequate neuropsychomotor development. In addition, it enables the understanding of the subject’s own body, actions and explorations of objects, people and the environment. Previous studies have evaluated 3 to 10 year-old children. Herein, we evaluate the tactile sensibility in adolescents. The aim of this study was to verify whether the rapid growth of the body changes the normal pattern of tactile sensibility in adolescents. Furthermore, we provide evaluation material that is easy to use, simple, and secure to handle, designed to attend the specific age range studied. Thirty-two young participants between 11 and 18 years old, sixteen males and sixteen females, were evaluated. The adolescents go to public school and present normal development patterns. Graphesthesia, stereognosia, and Semmes-Weinstein monofilament tests were performed to evaluate the sensibility on the ventral and dorsal sides of the right and left hands. A questionnaire was used to identify the relevant activities performed with the hands during the studied period. The adolescents tested were collaborative during the research and presented curiosity regarding the boxes used in the experiment. Results indicated alterations in the tactile sensibility on the dorsal side of the hands from 13-year- old males. The major activities indicated by the adolescents were writing and sports for males and writing and cleaning for females. First evidences of possible changes in the normal tactile sensibility during adolescence were observed in this study.

Diretrizes para o desenvolvimento e a avaliação de blogs de biblioteca

Blogging become popular due to its ease of use and publication, which influences the growth of digital information environments. Therefore, studies are needed to optimize the organization of information in the blog, to contribute in its development. Using the direct observation of nonparticipatory, analysis was performed on 6 blogs of university libraries to identify the elements of Information Architecture (IA) that is considered essential and optional for the structural development of a blog. Thus, were conducted planning guidelines for blogs and a model for its evaluation, and were proposed specific elements of IA for blogs, to contribute to the study of Digital Information Architecture.

Desenvolvimento de algoritmos para a avaliação quantitativa de imagens de fantomas mamográficos

There are many advantages when using a phantom for the evaluation of the mammographic images, one of them is to test the visibility of the distribution of objects that constitute it, and then, set the best image in order to obtain a diagnostic medical insurance, trying to reach the best risk - benefit ratio for the patient. Typically, the quality of the mammographic image is performed by subjective and quantitative assessments. This study developed algorithms that can quantitatively evaluate digital images (DICOM), obtained from mammographic phantom consisting of test objects. The results were adjusted by the response of the subjective evaluation performed by experts in radiology. This procedure aims to create an independence of the experts in radiology in daily tests of quality control in routine clinical diagnostic radiology

Desenvolvimento e validação de uma técnica quantitativa de análise de imagem para avaliação do teste do cometa corado pela prata

The comet assay is a method of DNA damage analysis widely used to quantify oxidative damage, crosslinks of DNA, apoptosis and genotoxicity of chemicals substances as chemical, pharmaceuticals, agrochemicals products, among others. This technique is suitable to detect DNA strand breaks, alkali-labile sites and incomplete excision repair sites and is based on the migration of DNA fragments by microeletroforesis, DNA migrates for the anode forming a “tail”, and the formed image has the appearance of a comet. The slides can be stained with fluorescence or silver, having differences in the microscopy type used for the analysis and the possibility of storage of the slides, moreover, the first one is a stained-method with more difficulties of accomplishment. The image analysis can be performed by a visual way, however, there is a disadvantage as the subjectivity on the results, that can be minimized by an automated method of digital analysis. This process was studied in this report with the aim to perceive the validation of the digital analysis turning it a quantitative method with larger reproductibility, minimizing the variability and imprecision due to the subjective analysis. For this validation we selected 50 comets photographed in a standardized way and printed, afterwards, pictures were submitted to three experienced appraisers, who quantified them manually. Later, the images were processed by free software ImageJ 1.38x, printed and quantified manually by the same appraisers. The intraclass correlation was higher to comet measures after image processing. Following, an algorithm of automated digital analysis from the measures of the comet was developed; the values obtained were compared with those 12 estimated manually after the processing resulting high correlation among the measures. The use of image analysis systems increases ...(Complete abstract click electronic access below)

Desenvolvimento de emulsão contendo C12 - 25 acid PEG 8 éster e avaliação da estabilidade com diferentes concentrações de óleo essencial de Achillea millefolium

Emulsões são utilizadas especialmente na área de cosméticos. São sistemas dispersos constituídos de duas fases líquidas imiscíveis (oleosa e aquosa), onde a fase dispersa ou interna é finamente dividida e distribuída em outra fase contínua ou externa. A estabilidade da emulsão é garantida com o uso de agentes emulsificantes, podendo ser melhorada com a ajuda de agentes espessantes, que aumentam a viscosidade. Os agentes espessantes podem ser: polímeros, álcoois, ácidos ou ésteres graxos e ceras naturais. O objetivo deste estudo foi avaliar a estabilidade de um sistema emulsionado não-iônico, apresentando como tensoativo emulsificante uma base auto emulsionável não-iônica e incorporado de óleo essencial em diferentes concentrações, para posterior avaliação da atividade antiirritante em cosméticos pós-barba e pós depilação. Para isto, foi necessário realizar os teste de estabilidade, que fornecem informações sobre a confiabilidade e a segurança das preparações, além da caracterização reológica completa, como auxiliar do desenvolvimento da preparação e do estudo de estabilidade. Foram realizados testes de estabilidade preliminar, que auxiliam na triagem das formulações e também realizou-se testes de estabilidade acelerada, com o objetivo de estimar o prazo de validade do produto. Com o objetivo de analisar o comportamento do produto durante o armazenamento e no momento do uso, estudou-se o comportamento reológico das preparações, onde avaliou-se as curvas de fluxo, a tixotropia e os testes oscilatórios. Os resultados obtidos mostraram que a emulsão proposta é estável frente aos testes de estabilidade, não apresentando alterações significativas quanto aos parâmetros analisados. Foi verificado que ela pode receber um ativo e liberá-lo, no entanto, as concentrações de óleo essencial de Achillea millefolium incorporadas... (Resumo completo, clicar acesso eletrônico abaixo)

Desenvolvimento e caracterização de sistemas líquido-cristalinos acrescidos de geoprópolis (Melipona scutellaris): avaliação da bioadesividade

A alta incidência da cárie no Brasil vem despertando muito interesse para estudos que visem combatê-la. Tem-se observado a procura pela utilização de produtos naturais (plantas medicinais e resinas) que buscam atividade contra a principal bactéria causadora da cárie, que é o Streptococcus mutans, entre estas a geoprópolis (Melipona scutellaris). Todavia, apesar de os estudos mostrarem ação destes produtos de origem animal contra este micro-organismo, muitas vezes a baixa substantividade (bioadesão) deste material ao substrato determina uma baixa efetividade. Este estudo promoveu o desenvolvimento de um sistema líquido cristalino objetivando aumento da substantividade da própolis. Foram desenvolvidos sistemas constituídos por dispersão de quitosana, ácido oleico e álcool cetílico propoxilado e etoxilado (Procetyl® AWS), de acordo com o diagrama de fases ternário. Foram selecionadas 3 formulações, as quais foram submetidas a ensaios de microscopia de luz polarizada, análise de textura, bioadesão e reologia. Os resultados mostraram que os sistemas são viáveis para incorporação do extrato de própolis, aumentando sua bioadesão em ensaios in vitro

Desenvolvimento e avaliação das atividades antioxidante e despigmentante in vitro de emulsões múltiplas a/o/a contendo dipalmitato kójico

Currently, there has been a growing concern for men and women with the appearance of the face and body, driven primarily by aesthetic standards set by the media. For this, the pharmaceutical and cosmetic industries have conducted numerous research projects aiming at the development of formulations that mitigate the aging and some skin disorders such as hipercromies. One of the most frequent pathologies of skin is melasma, a manifestation of hyperpigmentation caused by hipermelanogenesis symmetrical and progressive, caused usually by hormonal irregularities, exposure to sunlight and genetic factors. In addition to sunscreen, the treatment is indicated the use of depigmenting substances, among them the kojic dipalmitate (DK), which is cleaved into kojic acid (5- hydroxy-2-hydroxy-methyl-4H-piran-4-one) by esterase after absorption by the skin cells. The kojic acid inhibits the action of tyrosinase as a chelator of ions and promotes the reduction of eumelanin and its precursor monomer. To promote a controlled release and improve the stability of the system, the DK can be incorporated into multiple emulsions, that is, complex systems composed of two emulsifications, where the two types of emulsions (W/O and O/W or O/W and W/O) exist simultaneously, forming emulsions of type W/O/W or O/W/O. This work aimed to incorporate the DK in emulsion W/O/W, physical-chemical systems obtained and to evaluate the antioxidant and depigmenting action in vitro of the developed formulations. The physico-chemical characterization was performed by microscopic analysis, quantification and size distribution, determination of pH, conductivity, zeta potential and bioadhesive test of the formulations. The droplet size in accordance with the use of light microscopy and dynamic light scattering is approximately 1μm. The pH, electrical conductivity and bioadhesion have not changed with the addition... (Complete abstract click electronic access below)
