Satisfação do usuário com as tecnologias da informação nos serviços bancários

O presente trabalho, através da interdisciplinaridade entre Sistemas de Informação e Marketing, foi desenvolvido com o objetivo de fornecer uma avaliação do grau de satisfação do cliente bancário, pessoa-física, com a utilização das tecnologias de informática e telecomunicações na realização dos serviços bancários, na cidade de Porto Alegre. Foram consideradas como tecnologias da informação os terminais de autoatendimento, Automated Teller Machines (ATMs) para saques e depósitos, cash-dispenser, terminais de depósitos, terminais de extratos e saldos e dispensadores de cheques, localizados em agências, ante-salas de agências, quiosques em locais públicos e em postos de atendimento, e centrais telefônicas com atendimento humano e URA (Unidade de Resposta Audível). O método seguido foi o proposto por ROSSI & SLONGO (1998), com duas etapas distintas, uma exploratória e a outra descritiva. Os indicadores de satisfação foram selecionados através de levantamento de dados secundários. A pesquisa foi realizada nos meses de julho e agosto 2000, nas salas de auto-serviço do Banco do Brasil. Os clientes entrevistados deveriam estar familiarizados com os serviços telefônicos da empresa pesquisada e terem realizado alguma transação nos terminais de autoatendimento. Para as análises da pesquisa, foram considerados fatores sobre postos de auto-atendimento, processamento de transações, comunicação com clientes, segurança, atendimento nas centrais telefônicas e erros relacionados a computadores. Concluiu-se que o Banco do Brasil está muito bem posicionado quanto à satisfação de seus clientes no que se refere às centrais telefônicas e auto-atendimento, ao seu site Internet Banking e à empresa como um todo. Todos com uma satisfação próxima ao nível máximo. Através de técnicas estatísticas, identificou-se que o indicador que trata de “pagamentos de contas, taxas e tributos nos terminais de auto-atendimento” recebeu o maior índice de satisfação, assim como o fator comunicação com clientes; e o indicador “agilidade na solução e problemas registrados nas centrais telefônicas” recebeu o maior índice de importância, assim como o fator postos de auto-atendimento. Assim, analisou-se, definiu-se e realizouse um modelo para avaliação da satisfação do cliente com as tecnologias da informação.

Estudo ergonômico do posto de atividade discente em instituição de ensino superior

This research carried through an ergonomic study of the rank of learning activity of a IES, was applied a questionnaire with ergonomic pointers structuralized in scale to intervalar of semantic differential of 0 the 10, in 290 pupils with ages between 18 and 52 years distributed for 5 courses in 9 classrooms, the sample was of the simple random probabilist type. The used statistical techniques had been the descriptive analysis and the analysis of clusters through statistica software 5,0 considering p £ 0,0500. Involving the following 0 variable: Layout; Colors; Acoustics; Illumination; Temperature; Position; Didactic furniture, and Equipment. The gotten results point to consider that the layout of the rooms, the perception of acoustic comfort, the position of the pupils and the furniture of the searched classrooms had been the condicionantes that had been more distinguished negative how much to the perception of comfort of the user. The the 91,5 NPS varied of 57,9 dB(A) values above of recommended for classrooms in accordance with NBR 10152; NR 15; NR 17; It would carry nº 3214/1978, of the Ministry of the Work and searched literature. The Illumination registered interval of 139 the 966 Lux, values are of the limits of interval recommended for classrooms according to NBR 5413 and NR 17. The thermal temperature registered interval of 24° 25,9ºC; URA 41,6 79.1% and the 0.1 air speed 1,0 m/s, values above of recommended for classrooms according to NBR the 6401 and NR 17. The research still suggests that it would have associations between pains in the body the positions of the pupils and the furniture of the classrooms. The results suggest research especially add for the conditions thermal and acoustics of the classrooms

Dermatophytosis: association between ABO blood groups and reactivity to the trichophytin

Os autores investigaram a relação entre dermatofitose e grupo sanguíneo ABO através da tipagem sanguínea, identificação do dermatófito isolado e resposta imune celular específica de 40 indivíduos portadores desta micose. Verificaram que o fungo Trichophyton rubrum foi isolado em 54,5% dos pacientes, sendo mais frequente em indivíduos pertencentes ao grupo sanguíneo A. A resposta imune celular, avaliada através do antígeno tricofitina, foi positiva em 25% dos pacientes estudados; a presença de reações imediatas (30 min) foi verificada em 35%. A distribuição dos grupos sanguíneos entre pacientes com dermatofitose e grupo controle foi a seguinte: 47,5% x 36% grupo A, 40% x 50% grupo O, 12,5% x 11% grupo B. Embora os autores tenham encontrado um número maior de pacientes pertencentes ao grupo sanguíneo A e infectados pelo T. rubrum, não obtiveram evidência estatística de que esses indivíduos sejam mais suscetíveis as dermatofitoses.

Neurophysiological patterns of ulnar nerve neuropathy in leprosy reactions

Background: Leprosy neuropathy, despite being primarily demyelinating, frequently leads to axonal loss. Neurophysiological examination of the nerves during Type 1 (T1R) and Type 2 reactions (T2R) may give some insight into the pathophysiological mechanisms.Methods: Neurophysiological examinations were performed in 28 ulnar nerves during a clinical trial of steroid treatment effectiveness, 19 patients with T1R and nine with T2R. The nerves were monitored during a period of 6 months; there were eight assessments per nerve, for a total of 224 assessments. Nine neurophysiological parameters were assessed at three sites of the ulnar nerve. The compound motor action potential amplitudes elicited at wrist, elbow and above, as well as the conduction velocity and temporal dispersion across the elbow, were chosen to focus on the changes occurring in the parameters at the elbow tunnel.Results and Conclusion: Neurophysiological changes indicating axonal and demyelinating processes during both T1R and T2R were detected across the elbow. Changes in demyelination, i.e. a Conduction Block, as a primary event present during T2R, occurring as an acute phenomenon, were observed regularly; in T1R Temporal Dispersion, a subacute phenomenon, was seen. During treatment remyelination occurred after both types of reactions.

Genetic and physiological alterations occurring in a yeast population continuously propagated at increasing temperatures with cell recycling

This work investigated the effects of increasing temperature from 30 degrees C to 47 degrees C on the physiological and genetic characteristics of Saccharomyces cerevisiae strain 63M after continuous fermentation with cell recycling in a system of five reactors in series. Steady state was attained at 30 degrees C, and then the temperature of the system was raised so it ranged from 35 degrees C in the last reactor to 43 degrees C in the first reactor or feeding reactor with a 2 degrees C difference between reactors. After 15 days at steady state, the temperature was raised from 37 degrees C to 45 degrees C for 25 days at steady state, then from 39 degrees C to 47 degrees C for 20 days at steady state. Starter strain 63M was a hybrid strain constructed to have a MAT a/alpha, LYS/lys, URA/ura genotype. This hybrid yeast showed vigorous growth on plates at 40 degrees C, weak growth at 41 degrees C, positive assimilation of melibiose, positive fermentation of galactose, raffinose and sucrose. of 156 isolates obtained from this system at the end of the fermentation process, only 17.3% showed the same characteristics as starter strain 63M. Alterations in mating type reaction and in utilization of raffinose, melibiose, and sucrose were identified. Only 1.9% of the isolates lost the ability to grow at 40 degrees C. Isolates showing requirements for lysine and uracil were also obtained. In addition, cell survival was observed at 39-47 degrees C, but no isolates showing growth above 41 degrees C were obtained.

Anti-neutrophil cytoplasmic antibodies (ANCA) in the clinical forms of leprosy

Anti-neutrophil cytoplasmic antibodies (ANCA) are autoantibodies against enzymes present in primary granules of neutrophils and lysosomes of monocytes detected in systemic vasculitis and in other diseases, including infections, ANCA are markers of active Wegener granulomatosis, which presents some anatomo-pathologic and immune response features similar to those of leprosy. Thus, we raised the hypothesis that ANCA may be present in leprosy as markers specifically linked to the presence of vasculitis. The aim of this study was to determine the presence of ANCA in leprosy and its correlation with the clinical forms of the disease. Sera from 60 normal individuals and from 59 patients with different clinical forms of leprosy were studied. The patients were also allocated into reactional and nonreactional groups. By indirect immunofluorescence, ANCA were positive, an atypical pattern A-ANCA, in 28.8% of the patient sera. A-ANCA predominated, although not significantly (p >0,05), in the reactional groups (37.9% vs 20.0%), and in those at the lepromatous pole (41.6% vs 20.0%). There was no correlation between ANCA positivity and either disease duration, disease activity, or therapeutic regimen (p >0.05), An interesting finding was the correlation between ANCA and gender: 94.1% of ANCA-positive patients were males (p <0.01), a feature that so far has not been reported in ANCA-related diseases and for which there is no explanation at the moment. By ELISA, the sera of the lepromatous leprosy patients did not show activity against either PR3, MPO, HLE, the most common ANCA antigens. Because A-ANCA are nonspecific, this finding requires further investigation for the determination of the responsible antigen(s), in conclusion, A-ANCA are present in 28.8% of leprosy patients but are not related to vasculitis in the erythema nodosum leprosum reaction and are not a marker of a specific clinical form.

Renal lesions in leprosy: A retrospective study of 199 autopsies

In the present work, 199 patients with leprosy who underwent autopsy between 1970 and 1986 were retrospectively studied to determine the prevalence, types, clinical characteristics, and etiologic factors of renal lesions (RLs) in leprosy. Patients were divided into two groups: 144 patients with RLs (RL+) and 55 patients without RLs (RL-), RLs observed in 72% of the autopsied patients were amyloidosis (AMY) in 61 patients (31%), glomerulonephritis (GN) in 29 patients (14%), nephrosclerosis (NPS) in 22 patients (11%), tubulointerstitial nephritis (TIN) in 18 patients (9%), granuloma in 2 patients (1%), and other lesions in 12 patients (6%), AMY occurred most frequently in patients with lepromatous leprosy (36%; nonlepromatous leprosy, 5%; P < 0.01), recurrent erythema nodosum leprosum (33%; P < 0.02), and trophic ulcers (27%; 0.05 < P < 0.10), Ninety-seven percent of AMY was found in patients with lepromatous leprosy, 88% showed recurrent trophic ulcers, and 76% presented with erythema nodosum leprosum, NPS was found in older patients with arterial hypertension, neoplastic diseases, infectious diseases, and vasculitis associated with GN, Most patients with AMY presented with proteinuria (95%) and renal failure (88%), the most frequent causes of death were renal failure in patients with AMY (57%), infectious diseases in patients with GN (41%) and TIN (45%), and cardiovascular diseases in patients with NPS (41%), No difference in survival rates was observed among RL- patients and those with AMY, GN, NPS, or TIN.

AVALIACAO DA REACAO DE MITSUDA EM PACIENTES VIRCHOVIANOS INATIVOS ANTES E APOS IMUNOTERAPIA

In this study the immunopotentiator levamisole as well as a mixture of BCG/Mycobacterium leprae were investigated in inactive lepromatous leprosy patients by using the Mitsuda reaction as a parameter. Twenty lepromatous patients ten years ago classified as histologically negative for Mitsuda's test were divided into three groups: five patients that were only retested with Mitsuda antigen; eight patients that received oral levamisol and seven patients that received a mixture of alive BCG plus autoclaved M. leprae. The results indicated that: 1) the levamisole did not alter the reactivity to lepromin in any of the patients studied; 2) neither the changes in the reactivity to lepromin by using the mixture (3 cases) nor those that occurred spontaneously (3 cases) were clear. They properly reflected the natural variation of patients with some degree of resistance to Mycobacterium leprae.

Contribuição das moléculas de antígeno de histocompatibilidade leucocitária (HLA) para a contratura de Dupuytren em uma população do Sudeste do Brasil

Objetivo:O objetivo deste estudo foi investigar o fenótipo do HLA em pacientes com contratura de Dupuytren (CD) para verificar a correlação desses alelos com os fatores de risco para o desenvolvimento da CD na população brasileira.Métodos:Este foi um estudo de caso-controle de 25 pacientes com CD e 443 indivíduos saudáveis sem histórico de doenças associadas ao HLA. As tipagens classe I e classe II do HLA foram feitas utilizando o método iniciador de sequências específicas da reação em cadeia da polimerase.Resultados:O fenótipo HLA-B*18 foi observado em 32% dos pacientes e 10,5% do grupo controle. Contudo, os valores de p não permaneceram significativos após correção.Discussão:Apesar de termos observado um aumento na tendência de os pacientes com CD terem o alelo HLA-B*18, os resultados não foram estatisticamente significativos após correção. Esse alelo foi maior em pacientes de etnia italiana e/ou espanhola, locais com frequências superiores a 18% e 14%, respectivamente. São necessárias investigações adicionais com uma coorte maior de pacientes com CD para confirmar o possível papel do HLA nessa doença.

Mycobacterium marinum infection: a case report

The infection by Mycobacterium marinum in humans is relatively uncommon. When it occurs, it mainly affects the skin, usually with a chronic, indolent and benign evolution. The diagnosis requires a high index of suspicion, and a significant delay may be observed between the first symptoms to the final diagnosis. This present case reports a M. marinum infection in an immunocompetent patient that had a chronic undiagnosed injury on the dominant hand for at least five years. The patient had several medical consultations, without proper suspicion, hampering adequate diagnostic investigation. Histopathology detected tuberculoid granulomas, but showed no acid-fast bacilli. The culture in appropriate medium and the polymerase chain reaction-restriction enzyme analysis (PRA)-hsp65 confirmed the diagnosis. Treatment with clarithromycin (1 g/day) for three months was effective. Although uncommon, this infection is a contact zoonosis. Therefore, it is important for clinicians to be aware of this diagnosis and properly guide preventable measures to professionals that are in risk group.
