Abstract: reproductive phenology, floral biology, breeding system and pollinators were analyzed on cryptostegia madagascariensis individuals cultivated at federal university of vi?osa campus, municipality of vi?osa, zona da mata of minas gerais state. in addition, seed viability and vigour from naturally opened fruits were tested. seed germination from yellow-green pericarp closed fruits was also tested. flowering of c. madagascariensis occurs mainly in november and december. fruits (follicles) are exhibited during all year, but more frequently in january and february. flowers open during the day and last about 24 hours. they exhibit protandry, secondary pollen presentation and intragynoecial compitum, which results in the production of twin follicles (two follicles per flower). it is self-compatible, but spontaneous self-pollination does not occur due to morphological characteristics. bees should be the main pollinators, as they exhibited the pollinarium attached to their mouthparts. at least one pollinarium was removed per flower. however, the low natural fructification (2.7%) rate indicates that these insects are efficient for pollinaria removal, but less efficient for deposition of collected pollen. the follicles take four months to reach the maximum size (average of 6.44 cm length, 2.45 cm height and 3.4 cm width), and 210 days for opening. each follicle averaged 96.5 seeds. the ideal conditions for seed quality evaluation, from naturally opened follicles, were 30 oc constant temperature and no supplementary light, and counting occurred at the 7th days. seeds from closed follicles showed 93% germination under those conditions.
Sistema reprodutivo de Oxypetalum mexiae Malme (Asclepiadaceae), espécie endêmica de Vi?osa, MG, Brasil, em perigo de extin??o

Acta Botanica Brasilica , 2003, DOI: 10.1590/S0102-33062003000100010
Abstract: results of open-pollination (exposed flowers), in natural population, and cross and self-pollination, in cultivated individuals, are reported in o. mexiae. this species occurs at the reserva florestal mata do paraíso, a forest fragment with 195ha, whose original vegetation is part of the phytogeographic unit of the atlantic forest. o. mexiae is a climbing species of great dimension, which grows at the wood border, following the water flow. it is self-compatible, but spontaneous self-pollination does not occur for morphological reasons. seeds of xenogamous (40%) and autogamous (50%) fruit sets presented a high viability (respectively, 99 and 100%). no fruit was produced in natural population, indicating that this species presents reproductive limitation. this limitation is imposed by a low level of pollination, which restricts the number of fruit-set, and herbivory, which impedes the developing fruits to reach maturation. the low level of pollination may be related to habitat fragmentation. besides, o. mexiae habitat may further limit its distribution and abundance.

Abstract: S o reportados resultados de poliniza o aberta (flores expostas aos polinizadores), em indivíduos de O. mexiae de popula o natural, e de poliniza es manuais (poliniza o cruzada e autopoliniza o), em indivíduos cultivados. Essa espécie ocorre na Reserva Florestal Mata do Paraíso, fragmento de floresta com cerca de 195ha e cuja vegeta o original faz parte da unidade fitogeográfica de Floresta Atlantica. O. mexiae é trepadeira de grandes dimens es, que cresce na borda da mata, acompanhando curso d'água. é espécie autocompatível, mas autopoliniza o espontanea n o ocorre por raz es morfológicas. Sementes de frutos resultantes da xenogamia (40%) e autogamia (50%) apresentaram alta viabilidade (respectivamente, 99 e 100%). A frutifica o, em popula o natural, foi nula, indicando que essa espécie apresenta limita o reprodutiva. Essa limita o é imposta pelo baixo nível de poliniza o, que restringe o número de frutos produzidos, e pela herbivoria, que impede que os frutos em desenvolvimento alcancem a maturidade. O baixo nível de poliniza o pode estar relacionado à fragmenta o do hábitat. Além disso, há limita o na distribui o e abundancia de O. mexiae imposta pelo hábitat.
Sistema reprodutivo de Oxypetalum appendiculatum Mart. e Oxypetalum banksii Roem. & Schult. subsp. banksii (Asclepiadaceae)
Vieira, Milene Faria;Shepherd, George John;
Acta Botanica Brasilica , 1999, DOI: 10.1590/S0102-33061999000300002
Abstract: studies on the breeding systems of o. appendiculatum and o. banksii subsp. banksii were carried out at vi?osa, minas gerais state, southeastern brazil. both species are self-compatible and seeds that resulted from self- and cross-pol linatio'ns presented a high viability. the low rate of fruit set in o. banksii subsp. banksii flowers exposed to visitors (open pollination) may be related to the lack of pollination (extrinsic factor). in o. appendiculatum the low rate of fruit set can be related to intrinsic factors, regulated by the plant itself. interspecific pollinations resulted in viable seeds and the f1 hybrid presented 64% of fertile flowers; this hybrid has not yet been found under natural conditions. self-pollinations in f1 flowers also yielded viable seeds.

Scientia Medica , 2009,
Abstract: Objetivos: o objetivo deste estudo foi avaliar alguns aspectos da atividade assistencial na unidade de interna o de curta dura o do servi o de urgência pediátrica do Hospital de S o Teotónio, em Viseu, Portugal, com ênfase na evolu o dos casos que regressaram ao servi o de urgência nas 72 horas seguintes à alta. Métodos: foi feita uma revis o dos prontuários das crian as que, tendo tido alta da unidade, regressaram à mesma sem que isso tivesse sido previsto, nas 72 horas seguintes, durante um período de 12 meses. Foram analisados os diagnósticos iniciais e os estabelecidos na readmiss o. Resultados: em 2005 foram atendidas no servi o de urgência 33. 211 crian as/adolescentes, e destas, 1. 395 (4,2%) foram admitidas na unidade de interna o de curta dura o. Do total das 905 (65%) que tiveram alta dessa unidade para o domicílio, 70 (7,7%) regressaram de modo n o previsto ao servi o de urgência nas 72 horas seguintes. As principais causas de retorno n o programado foram infe o urinária, gastroenterite aguda e síndrome febril, verificando-se serem mais frequentes na faixa etária abaixo dos dois anos. Em 21,4% dos casos houve necessidade de reinterna o na mesma unidade. Entre este grupo de 70 crian as, 10% tinham novos diagnósticos de maior significado clínico. Houve um caso de oclus o intestinal que motivou interven o cirúgica. Conclus es: os dados obtidos s o úteis para a caracteriza o do perfil de pacientes com readmiss es n o-previstas, para que novas interven es sejam implementadas para melhorar o atendimento desse grupo de pacientes. Aims: The aim of this study was to evaluate different clinical aspects in a short term stay unit of the emergency room of S o Teotónio’s Hospital, Viseu, Portugal, with emphasis on the evolution of the cases that have returned to the emergency room, within 72 hours after discharge. Methods: Medical records of children discharged from this unit that returned to the emergency room on the following 72 hours, in a 12 months period, were reviewed. We have analyzed the initial diagnosis and those made on readmission. Results: In 2005, 33,211 children/adolescents were registered in the emergency room, and 1,395 (4. 2%) were admitted in the short term stay unit. From this sample, 70 out of 905 discharges (7. 7%) returned unexpectedly to the emergency room on the following 72 hours. The leading causes of these returns were urinary tract infection, acute gastroenteritis and fever, more frequently in children younger than two years of age. From this group of 70 children, 21. 4% needed readmission in the unit, and 10% had a n
Fenologia de flora??o e sistema reprodutivo de três espécies de Ruellia (Acanthaceae) em fragmento florestal de Vi?osa, Sudeste brasileiro

Abstract: this work is a continuation of studies on the reproductive biology of angiosperm species in the municipality of vi?osa, "zona da mata", minas gerais state, brazil. the aim of this work was to analyze the flowering phenology and the breeding system of three co-occurring species of ruellia: r. brevifolia (pohl) c. ezcurra and r. menthoides (nees) hiern, both cleistogamous, and r. subsessilis (nees) lindau. seed germination was tested and the occurrence of vegetative propagation verified. ruellia subsessilis flowered throughout the year, with a peak in october. ruellia brevifolia produced flowers mainly from february to july, with a flowering peak in march. ruellia menthoides produced flowers from august to december with a flowering peak in september. all species are self-compatible; ruellia brevifolia and r. menthoides are facultative autogamous species and r. subsessilis is a facultative xenogamous species. high percentages of normal seedlings (from 67% up to 83%) were obtained from seeds produced through selfing. besides sexual reproduction, the species showed vegetative propagation, i.e., branch fragments segregated from the motherplant, which develop adventitious roots. the species, therefore, showed sexual and asexual reproductive strategies. the former are distinct flowering peak, autogamous or allogamous flowers as well as ornitophilous or mellittophilous ones, and cleistogamous flowers. however, the result of sexual strategies was common to all of them, i.e., production of fruits with viable seeds during the entire year. the balance among the various reproductive mechanisms seems to confer to these species a high degree of adaptation in altered environments as shown in areas of their occurrence at the forest fragment studied.
A ordem dos atributos afeta a avalia??o de qualidade ? Uma investiga??o empírica a partir da vers?o mais recente do modelo SERVQUAL
Carvalho, Frederico A. de;Leite, Valdecy Faria;
Revista de Administra??o Contemporanea , 1997, DOI: 10.1590/S1415-65551997000100003
Abstract: the purpose of this paper is to investigate the effects of the order of presentation of attribute scales in service quality surveys that use the servqual instrument in combination to a ranking of the attributes. it is hoped that the paper will be of interest to quality research practitioners. the real case presented here applies the most recent, 3-columns version of servqual to evaluate service quality of brazilian postal services from a convenience sample of 540 clients firms. to avoid having to rank 39 attributes, an intermediary procedure (based on a shorter list of attributes and weighting scheme) is proposed. four different ways of placing the 39 quality attributes have been used to test for the existence of an order effect. the test of both pearson and spearman correlations coefficients (calculated for each pair select from those versions) has rejected the null hypothesis of inexistence of the order effect. one interesting implication is that the original list of 22 attributes may be then increased to take into account specific of a particular service.

Bernadete Valente Faria,Ligia Silva Leite
Meta : Avalia??o , 2012,
Abstract: objetivo do estudo consiste em avaliar os resultados do Programa de Obesidade Mórbida do Hospital de For a Aérea do Gale o (HFAG). Foram consultados 46 pacientes e analisados aspectos da qualidade de vida dos operados em rela o aos que aguardavam a cirurgia. A natureza do objeto da avalia o conduziu à triangula o de métodos e técnicas de coleta de dados, através das abordagens quantitativas e qualitativas. Os dados foram coletados através (a) da aplica o do questionário do Impacto do Peso sobre a Qualidade de Vida (QV); (b) realiza o do grupo focal; (c) levantamento de dados dos prontuários dos pacientes operados em cirurgia bariátrica, para verificar a frequência a consultas após a cirurgia. Os resultados da avalia o revelam que a maioria dos pacientes que se submeteram à cirurgia bariátrica no HFAG é do sexo feminino, casado, com escolaridade de nível superior, a média de idade é de 46 anos, as doen as de comorbidade após cirurgia diminuíram, tendo sido extintas em alguns pacientes sendo que no primeiro ano após a cirurgia se tem a maior perda de peso. Constatou-se uma melhora significativa na QV dos pacientes operados em rela o aos pacientes que n o operaram. Os resultados demonstram um impacto positivo no cotidiano dos pacientes após a perda de peso, aumentando a QV nos domínios de fun o física, autoestima, vida sexual, constrangimento público e trabalho, maior independência nas atividades de vida diária, capacidade funcional, e integra o social.
Polimorfismo floral em Valeriana scandens L. (Valerianaceae)
Duarte-Silva, Erica;Vieira, Milene Faria;Bittencourt Jr, Nelson Sabino;Garcia, Flávia Cristina Pinto;
Acta Botanica Brasilica , 2010, DOI: 10.1590/S0102-33062010000300030
Abstract: three floral morphs were found in valeriana scandens l.: perfect, pistillate 1, and pistillate 2. in perfect flowers, the corolla is longer than in the other morphs, with reflexed lobes at anthesis and a prominent gibbus at the tube base; anthers are longer and contain viable pollen grains; the pistil has a short included style/stigma and the smallest ovary, but a structurally normal embryo sac similar to that of the other morphs. in pistillate 1 flowers, the corolla is intermediate in size, and has radially displayed lobes at anthesis, and a softly prominent gibbus; anthers are small and devoid of pollen; the pistil shows a long exerted style/stigma. in pistillate 2 flowers, the corolla also has radially displayed lobes; anthers are similar in length to the perfect flower, but narrower, and contain nonviable pollen grains; the style/stigma is as short as in perfect flowers, and is exerted as in pistillate 1 flowers. the three morphs produce viable seeds, and have a nectary formed by single-celled trichomes located on the inner face of the gibbus. pistillate 2 and perfect flowers have a septum that isolates the gibbus from the rest of the corolla tube, forming a nectariferous chamber. the gynomonoecious-gynodioecious sexual expression verified in v. scandens l. is a novelty for valerianaceae.
