Abstract: Fatores individuais, técnicos, sociais e políticos têm gerado resistência à implanta o de sistemas informatizados no contexto da administra o pública. Assim, este trabalho investiga, por meio de um estudo de caso múltiplo, a implanta o de sistema de folha de pagamento de servidores públicos, a respectiva rea o dos usuários, em seu contexto organizacional, ao mesmo, e o desfecho final em termos da aceita o ou n o do citado sistema. S o analisados dois casos em administra es estaduais distintas: o poder executivo de um estado brasileiro (caso A) e o tribunal de justi a de outro estado (caso B). Um mesmo sistema foi contratado nos dois casos, propiciando a compara o entre as duas experiências. Enquanto, no caso A, o sistema estava em curso final de implanta o, superadas resistências com relativo sucesso, no caso B, a implanta o foi suspensa, permanecendo pendente a sua efetiva aceita o. A análise aplica um referencial teórico que integra fatores geradores de resistência, relacionados com as dimens es individual (pessoas) e técnica (sistema), e com a intera o social e política entre os usuários do sistema e o ambito da organiza o. Ao final, o artigo identifica diversos tipos de comportamento de resistência, sua inter-rela o e transforma o ao longo da trajetória de implementa o dos sistemas, e os desfechos contrastantes ocorridos nos dois casos. ----- RESISTANCE TO THE IMPLEMENTATION OF A PAYROLL SYSTEM IN THE PUBLIC ADMINISTRATION: A MULTI-CASE INVESTIGATION ----- ABSTRACT ----- Personal, technological, social and political issues have triggered resistance to information systems within public administration. Thus, this research investigates, via a multiple case study, the implementation of a payroll system in the public administration. The study investigates the type of reaction of the civil servants to that system within their organizational realm, as well as whether or not the system was accepted by them. The article addresses two case studies, namely one at the executive level of a Brazilian state (case A) and the other at the justice department of another Brazilian state (case B). Both states hired the development of the same payroll system, whereby enabling comparison between these two endeavors. While in case A the system was about to be fully implemented after the overcoming of several hurdles, in case B the system implementation was halted as it was not accepted by the organization where it would be implemented. The research uses a theoretical frame that binds resistance factors accrued from persons, the system, as well as from the so

Revista Brasileira de Cardiologia Invasiva , 2009, DOI: 10.1590/S2179-83972009000400007
Abstract: background: female gender is an independent predictor of vascular complications after invasive coronary procedures. while reducing the risk of bleeding related to the puncture site, radial access in women might be particularly beneficial in reducing adverse events. method: consecutive female patients undergoing diagnostic and therapeutic coronary procedures using radial access were enrolled in a prospective registry. the success of the technique, the procedure and fluoroscopy times, vascular complications and severe periprocedural cardiovascular adverse events were analyzed. in addition, a comparative analysis between women < 65 and > 65 years old was carried out to determine the applicability of the technique among elderly patients. results: between may 2008 and september 2009, 988 women underwent invasive coronary procedures using the radial access. mean age was 62.5 years, and 32.4% were diabetics. the success rate was 97.1%. there was a low incidence of complications, including asymptomatic occlusion of the radial artery (2.8%), hematomas (2.4%), and severe bleeding (0.2%). except for a longer duration of fluoroscopy while performing angioplasties, women > 65 years showed similar success rates compared to those < 65 years. conclusions: ts, and virtually no severe bleeding related the puncture site.

Revista Brasileira de Cardiologia Invasiva , 2010, DOI: 10.1590/S2179-83972010000300011
Abstract: background: radial spasm is considered one of the main reasons of failure in the transradial approach. the prolonged procedure time, use of large diameter catheters, catheter frictions during manipulation and number of catheters used are among the main causes of radial spasm. the use of catheters dedicated to radial access could minimize such factors, with a consequent reduction in the incidence of spasm. methods: prospective registry of consecutive patients with suspected coronary artery disease undergoing coronary angiography using the right radial access, with 5 f sheaths. we compared the procedural success, the strategy success, duration of the procedure, fluoroscopy time and the number of catheters used among patients who used the dedicated catheter (optitorquetm tig) with those using the judkins catheter (jl/jr). results: from september 2009 to july 2010, 300 patients using the dedicated catheter (group i) were included and compared with a control group with the same number of patients whose procedure was performed using judkins catheters (group ii). there was a higher procedure success rate in group i (100% vs. 98%; p = 0.03) and no difference in the chosen strategy success (93.7% vs. 95%; p = 0.59). there was a statistically significant decrease in the duration of the procedure (13.6 ± 6 min vs. 15 ± 6.4 min; p = 0.007), in fluoroscopy time (2.5 ± 1.6 min vs. 3.1 ± 2.2 min; p = 0.0009) and number of catheters (1.1 ± 0.3 vs. 2.1 ± 0.6 min; p < 0.0001) in group i. there was no difference in the occurrence of spasm (4.7% vs. 5.7%; p > 0.99). conclusions: the use of a dedicated radial catheter was effective and safe, with a significant reduction in fluoroscopy time, length of procedure and the total number of catheters used, with a possible reduction in the cost of the procedure, but no reduction in the incidence of spasm or other complications.

Revista Brasileira de Cardiologia Invasiva , 2008, DOI: 10.1590/S2179-83972008000300012
Abstract: background: the use of the transradial approach is associated with low rates of complications at the puncture site, reduced costs, shorter hospital stay and is more confortable to the patient. however, its is not feasible in 5%15% of the cases due to significant anatomic variations, vessel spasms and negative results in the allen's test. the aim of this study was to evaluate the safety and efficacy of the transulnar access as an alternative approach in these situations. methods: coronary procedures performed through the transulnar approach were included in a prospective registry. we evaluated the success rates, defined as adequate coronary opacity in coronary angiography or a percutaneous coronary intervention (pci) with residual stenosis < 30%, with no need to change the access site; procedure and fluoroscopy times and the rate of in-hospital and 30-day complications. results: between may 2007 and may 2008, 102 coronary procedures were included in the registry. the mean age was 61 ± 11 years, 53% were female patients and 34% were diabetic. success rates were 94.5% and 100% for coronary angiography and pci, respectively. there was a low rate of complications, including 2% of asymptomatic occlusion of the ulnar artery and 1% of hematoma not requiring vascular repair or blood transfusion. conclusions: the use of transulnar access in coronary procedures is safe and efficient, with high success rates and virtually no complications related to the puncture site. it is a good alternative for those experienced with the transradial approach.

Arquivos Brasileiros de Cardiologia , 2011, DOI: 10.1590/S0066-782X2011005000026
Abstract: background: although the radial approach offers an unquestionable result in terms of reduction of vascular complications and occurrence of severe bleeding in comparison to the femoral approach, so far it has only been used in few centers which elected it as the preferential access. objective: to evaluate the current status of percutaneous coronary interventions in brazil, as regards the use of the radial approach. methods: analysis of data spontaneously recorded in central nacional de interven??es cardiovasculares - cenic (national center for cardiovascular interventions) from 2005 to 2008, in a total of 83,376 procedures. results: the radial approach was used in 12.6% of the procedures performed, and the femoral approach, in 84.3%. the remaining 3.1% corresponded to brachial artery dissection or puncture. with a success rate of 97.5%, the choice of the radial approach was associated with a significant reduction of vascular complications in comparison to the femoral approach (2.5% versus 3.6 %, p < 0.0001). conclusion: the radial approach remains uncommonly used in brazil, and this is possibly explained by the lack of training programs, uncertainties regarding the learning curve, and the lack of large-scale studies corroborating the benefits demonstrated to date.

Arquivos Brasileiros de Cardiologia , 2008, DOI: 10.1590/S0066-782X2008001600017
Abstract: the transradial approach is safe and effective for coronary procedures. however, its use may be compromised in cases of variations in radial artery anatomy, spasms, and negative allen's test. the transulnar approach emerges as a viable alternative to transradial approach. we report on a patient who underwent primary angioplasty via ulnar artery without ischemic hand complications despite prior occlusion of the ipsilateral radial artery.

Revista Brasileira de Cardiologia Invasiva , 2010, DOI: 10.1590/S2179-83972010000100009
Abstract: background: transradial access has gained greater acceptance and interest due to the lower incidence of bleeding and local vascular complications and greater comfort for the patient. in centers where it is used as the preferred access, repeat transradial procedures are becoming routine. this study is aimed at assessing the safety, efficacy and limitations of repeated procedures in the daily practice. method: consecutive patients undergoing diagnostic coronary procedures using the transradial access were included in a prospective registry. those who used the radial access more than once (group i) were compared with those who used it at one time only (group ii). the success of the technique, procedural and fluoroscopic times, vascular complications and major adverse cardiovascular events were evaluated. in addition, in group i we obtained the frequency, success and limitations in the number of repeated procedures. results: from may 2008 to december 2009, 232 patients with previous right transradial access underwent diagnostic coronary procedures using the same access route and were compared to 1,857 patients who used it at one time only. the procedure success rate (99.5% vs. 98.1%; p = 0.17), the procedural time (15.78 ± 6.8 min vs. 15.54 ± 7.7 min; p = 0.62) and fluoroscopic time (3.26 ± 3.01 min vs. 3.26 ± 2.42 min; p > 0.99) were similar between groups. the procedure success rate did not differ among group i patients with > 2 repetitions, when compared with those who used it at one time only (99.2% vs. 100%; p = 0.99). in the late follow-up of group i patients, 602 procedures were carried out with a success rate of 98.9%, although there was a non-significant decrease of the success rate after each repetition up to the fourth procedure. conclusion: the reuse of transradial access in diagnostic coronary procedures has proven to be effective, taking into consideration its high success rate and low complication rates in most of the patients, despite the limitation in t
Constru??o de pilhas elétricas simples: Um experimento integrado de química e física
OLIVEIRA, Luiz Antonio Andrade de;VALLE, Gisele Gomes;ZANLUQUI, Luís André;
Eclética Química , 2001, DOI: 10.1590/S0100-46702001000100018
Abstract: in this article are described simple and inexpensive ways of assembling galvanic cells, using zinc, magnesium and copper plates directly immersed in electrolytic solutions. citric fruit juices, or even tap water, can be used as electrolytic solutions. voltage and current produced by the electrochemical cells are enough for running electrical devices with small power demand, such as analogical and digital clocks. the experiments can be explored as simple demonstrations of transformation of chemical into electrical energy for elementary school students, or as interdisciplinary experiments of physics and chemistry for more advanced students.

Knorst, André Marcelo;Vanti, Adolfo Alberto;Andrade, Rafael Alejandro Espín;Johann, Silvio Luiz;
JISTEM - Journal of Information Systems and Technology Management , 2011, DOI: 10.4301/S1807-17752011000300003
Abstract: this paper develops the strategic alignment of organizational behavior through the organizations′ image, prioritization and information security practices. to this end, information security is studied based on the business requirements of confidentiality, integrity and availability by applying a tool which integrates the strategic, tactical and operational vision through the following framework: balanced scorecard - bsc (strategic) x control objectives for information and related technology - cobit (tactical) x international organization for standardization - iso/international electro technical commission - iec27002 (operational). another image instrument of the organization is applied in parallel with this analysis to identify and analyze performance involving profiles related to mechanistic, psychic prisons, political systems, instruments of domination, organisms, cybernetics, flux and transformation (morgan, 1996). finally, a model of strategic prioritization, based on compensatory fuzzy logic (espin and vanti, 2005), is applied. the method was applied to an industrial company located in southern brazil. the results with the application show two organizational images: "organism" and "flux and transformation ". the strategic priorities indicated a significant search for new business services and international markets. regarding protection of information, security found the gap between "minimum" and "reasonable" and in domain 8 (hr) of standard iso/iec27002, considered 71% protection as "inappropriate" and "minimal" in the it governance context.
