APPLICATIONS OF ARTIFICIAL-INTELLIGENCE IN ORGANIC-CHEMISTRY .17. NEW PROGRAMS IN THE SISTEMAT PROJECT

This work describes the new improvements of the SISTEMAT project, one system for structural elucidation mainly in the field of Natural Products Chemistry. Some examples of the resolution of problems using C-13 Nuclear Magnetic Resonance and Mass Spectroscopy are given. Programs to discover new heuristic rules for structure generation are discussed. The data base contains about 10000 C-13 NMR spectra.

Cytochemistry and polarization microscopy of amphibian sperm cell nuclei presumed to differ in basic protein composition

The pattern of availability of free DNA phosphates, and the kind of DNA-protein complex arrangement, both induced by nuclear basic proteins, and the richness in arginine residues in these proteins were investigated cytochemically and cytophysically in spermatozoa of the South-American Hylidae species, Hyla fuscovaria and Hyla biobeba. The aim was to demonstrate differences at the level of sperm histones in two species of Hyla until recently considered to be congeneric. The results indicated differences in the spermatozoal nuclear basic proteins and DNA-protein complexes when the two species were compared. The spermatozoa of Hyla biobeba were assumed to be likely to contain a Bloch's ''type 3'' protein type (intermediate sperm basic protein), similarly to Hyla species of North and Central America. on the other hand, the data obtained for the spermatozoa of Hyla fuscovaria indicated that they contain a protamine or protamine-like protein, differing from Hyla biobeba and Hyla species of North and Central America. It is suggested that the differences reported here may be genus-specific, since Hyla fuscovaria has recently been reclassified as Scinax fuscovaria based on parameters other than sperm histone types. These findings are in agreement with the general view of a wide variability in sperm nuclear proteins in the Anura group.

Teoria da Formação e Avaliação no currículo de Educação Física

Having as reference the curricular proposals that composed the new directives for Formation of Professors for the Basic Education, Full Licence in Brazil, it was aimed to analyze in the pedagogic project of a Physical Education Licence course, the professional profile proposed, the conceptual orientation adopted (curriculum model) as well the evaluation proposed in the curriculum. These results obtained from the descriptive study have contemplated documental source and content analysis approach, utilizing as basis for discussion of the results the formation theory. Among the most significant data it was established that, the presented professor profile must consider an Academic, Technological, Practical and Socio-Reconstructionist orientation, detaching during the evaluation process a high skill level in Academic Orientation, as well remarking that the evaluation is presented as a great gap in the pedagogic project.

Undergraduate research in medical education: a descriptive study of students' views

Background: Medical students engage in curricular and extracurricular activities, including undergraduate research (UR). The advantages, difficulties and motivations for medical students pursuing research activities during their studies have rarely been addressed. In Brazil, some medical schools have included undergraduate research into their curriculum. The present study aimed to understand the reality of scientific practice among medical students at a well-established Brazilian medical school, analyzing this context from the students' viewpoint.Methods: A cross-sectional survey based on a questionnaire applied to students from years one to six enrolled in an established Brazilian medical school that currently has no curricular UR program.Results: The questionnaire was answered by 415 students, 47.2% of whom were involved in research activities, with greater participation in UR in the second half of the course. Independent of student involvement in research activities, time constraints were cited as the main obstacle to participation. Among students not involved in UR, 91.1% said they favored its inclusion in the curriculum, since this would facilitate the development of such activity. This approach could signify an approximation between the axes of teaching and research. Among students who had completed at least one UR project, 87.7% said they would recommend the activity to students entering the course.Conclusion: Even without an undergraduate research program, students of this medical school report strong involvement in research activities, but discussion of the difficulties inherent in its practice is important to future developments.

As políticas de formação do arte educador no século XXI: o caso da UNESP no Estado de São Paulo

This paper deals with the training of art educators, focusing on the courses offered at public universities in the state of São Paulo, where, specifically the pedagogical approach of training curricula of grades offered at UNESP, campus of São Paulo and Bauru. In the current situation have been proposed, from training in undergraduate courses, new tasks and responsibilities to work teaching the teacher in order to develop this educational increasingly effective so as to ensure efficient productivity autonomous learner in the process cognitive development in basic education, the teacher being assigned the task of stimulating that process and manage situations of educational work as a way of systematizing knowledge. The research consisted of questioning whether that teacher training allowed contact with the educational resources necessary for teaching, under current conditions assigned by the neoliberal conjuncture educational work of art educator with a view to the formation of aesthetic sensibility of the students from the class working, privileged pupils of public schools, to contribute to establishing the apprehension about the pedagogical training of art educators to confront the reality school, considering the specificity of action of these teachers. Therefore we conducted a desk study of existing legislation and the National Curriculum Guidelines that guide teacher training, correlating them to Pedagogical Policy Projects and curricula of undergraduate courses in Arts Education and / or Visual Arts courses UNESP. The work of desk research, quantitative and analytical, refers strictly pedagogical part, amid restructuring curriculum established by the undergraduate courses in the periods 2003 to 2011, with the promulgation of the CNE/ CP nº. 9 / 2001 and the Resolution CNE/CP n.º 1/2002 and n.º 2/2002...

Dysglycemias in pregnancy: from diagnosis to treatment. Brazilian consensus statement

There is an urgent need to find consensus on screening, diagnosing and treating all degrees of DYSGLYCEMIA that may occur during pregnancies in Brazil, considering that many cases of DYSGLYCEMIA in pregnant women are currently not diagnosed, leading to maternal and fetal complications. For this reason the Brazilian Diabetes Society (SBD) and the Brazilian Federation of Gynecology and Obstetrics Societies (FEBRASGO), got together to introduce this proposal. We present here a joint consensus regarding the standardization of clinical management for pregnant women with any degree of Dysglycemia, on the basis of current information, to improve medical assistance and to avoid related complications of Dysglycemia in pregnancy to the mother and the fetus. This consensus aims to standardize the diagnosis among general practitioners, endocrinologists and obstetricians allowing the dissemination of information in basic health units, public and private services, that are responsible for screening, diagnosing and treating disglycemic pregnant patients.

Mathematics teaching life histories in the study of teachers' perceptions of change

The aim of this paper is to discuss teachers' perceptions of change in their thought and/or practice over time and their perceptions of what kind of experiences or challenges might have influenced those changes. Two mathematics teaching life histories of Brazilian teachers are examined, considering a context of curriculum development in the state of São Paulo, Brazil. Reflection on teachers' thought and practice and interest in their own development, including interest in their own learning of mathematics, seemed to be the most important internal aspects influencing change and development. Close support seemed to be the most important external aspect. The retrospective analysis put a good face on personal change and development. (C) 2000 Elsevier B.V. Ltd. All rights reserved.
