Patients' expectations and satisfaction of complete denture therapy and correlation with locus of control

P>Considering the importance of patients' satisfaction with complete denture therapy and the influence of psychosocial aspects and expectations regarding satisfaction with their dentures, the present study aimed to test for a correlation between locus of control profiles and expectations before and satisfaction after complete denture therapy. Sixty-four patients rated their expectations for aesthetic and functional results of complete denture therapy on a 10-cm visual analogue scale (VAS), using scores from 0 (worst results) to 10 (best results). A similar questionnaire was used regarding satisfaction after final denture adjustments. Patients also answered a locus of control questionnaire in the initial interview. anova and a chi-squared test were used to test for correlations among ratings, patient gender and locus of control profiles. The significance level adopted was 0 center dot 05. The expectation ratings before treatment were significantly lower than the post-treatment completion ratings, both for aesthetics (P < 0 center dot 001) and function (P = 0 center dot 004). There was no correlation between locus of control profiles and patients' ratings or between gender and VAS scores. No correlation was found between locus of control profiles and scores for expectations before and satisfaction after complete dentures.

Optimised placement of control and protective devices in electric distribution systems through reactive tabu search algorithm

Optimised placement of control and protective devices in distribution networks allows for a better operation and improvement of the reliability indices of the system. Control devices (used to reconfigure the feeders) are placed in distribution networks to obtain an optimal operation strategy to facilitate power supply restoration in the case of a contingency. Protective devices (used to isolate faults) are placed in distribution systems to improve the reliability and continuity of the power supply, significantly reducing the impacts that a fault can have in terms of customer outages, and the time needed for fault location and system restoration. This paper presents a novel technique to optimally place both control and protective devices in the same optimisation process on radial distribution feeders. The problem is modelled through mixed integer non-linear programming (MINLP) with real and binary variables. The reactive tabu search algorithm (RTS) is proposed to solve this problem. Results and optimised strategies for placing control and protective devices considering a practical feeder are presented. (c) 2007 Elsevier B.V. All rights reserved.

Cárie precoce: influência de variáveis sócio-comportamentais e do locus de controle da saúde em um grupo de crianças de Araraquara, São Paulo, Brasil

O objetivo deste estudo foi verificar a relação entre a cárie precoce, variáveis sócio-comportamentais e o locus de controle da saúde em um grupo de crianças de 24 a 35 meses de idade de Araraquara, São Paulo, Brasil. Foram envolvidas todas as crianças de ambos os sexos, na mencionada faixa etária, matriculadas em sete Centros Municipais de Educação e Recreação Infantil, totalizando 110 crianças. Os exames foram realizados por um examinador, previamente, calibrado para a aplicação dos critérios propostos pela OMS para determinação da condição dentária. Um questionário foi respondido pelas mães, sendo que seu conteúdo incluía informações referentes às características sócio-econômicas, comportamentos e atitudes relacionados à saúde bucal da criança, além da escala multidimensional do locus de controle da saúde. A prevalência de cárie precoce (lesões cavitadas e não cavitadas) foi de 28,2%. Observou-se associação significativa entre a escolaridade paterna (p = 0,01) e cárie precoce; não houve associação significativa entre as médias de nenhuma das subescalas do locus de controle e a cárie precoce. Os resultados sugerem que os pais não devam ser tidos apenas como provedores, mas como uma importante influência no desenvolvimento infantil como um todo.

Frequency and genetic diversity of the MAT1 locus of Histoplasma capsulatum isolates in Mexico and Brazil

The MAT1-1 and MAT1-2 idiomorphs associated with the MAT1 locus of Histoplasma capsulatum were identified by PCR. A total of 28 fungal isolates, 6 isolates from human clinical samples and 22 isolates from environmental (infected bat and contaminated soil) samples, were studied. Among the 14 isolates from Mexico, 71.4% (95% confidence interval [95% CI], 48.3% to 94.5%) were of the MAT1-2 genotype, whereas 100% of the isolates from Brazil were of the MAT1-1 genotype. Each MAT1 idiomorphic region was sequenced and aligned, using the sequences of the G-217B (+mating type) and G-186AR (-mating type) strains as references. BLASTn analyses of the MAT1-1 and MAT1-2 sequences studied correlated with their respective+ and-mating type genotypes. Trees were generated by the maximum likelihood (ML) method to search for similarity among isolates of each MAT1 idiomorph. All MAT1-1 isolates originated from Brazilian bats formed a well-defined group; three isolates from Mexico, the G-217B strain, and a subgroup encompassing all soil-derived isolates and two clinical isolates from Brazil formed a second group; last, one isolate (EH-696P) from a migratory bat captured in Mexico formed a third group of the MAT1-1 genotype. The MAT1-2 idiomorph formed two groups, one of which included two H. capsulatum isolates from infected bats that were closely related to the G-186AR strain. The other group was formed by two human isolates and six isolates from infected bats. Concatenated ML trees, with internal transcribed spacer 1 (ITS1) -5.8S-ITS2 and MAT1-1 or MAT1-2 sequences, support the relatedness of MAT1-1 or MAT1-2 isolates. H. capsulatum mating types were associated with the geographical origin of the isolates, and all isolates from Brazil correlated with their environmental sources. © 2013, American Society for Microbiology.

Influence of distance, geometry and number of control stations on quality of local geodetic networks for the purpose of georeferencing of rural properties

The implementation of local geodetic networks for georeferencing of rural properties has become a requirement after publication of the Georeferencing Technical Standard by INCRA. According to this standard, the maximum distance of baselines to GNSS L1 receivers is of 20 km. Besides the length of the baseline, the geometry and the number of geodetic control stations are other factors to be considered in the implementation of geodetic networks. Thus, this research aimed to examine the influence of baseline lengths higher than the regulated limit of 20 km, the geometry and the number of control stations on quality of local geodetic networks for georeferencing, and also to demonstrate the importance of using specific tests to evaluate the solution of ambiguities and on the quality of the adjustment. The results indicated that the increasing number of control stations has improved the quality of the network, the geometry has not influenced on the quality and the baseline length has influenced on the quality; however, lengths higher than 20 km has not interrupted the implementation, with GPS L1 receiver, of the local geodetic network for the purpose of georeferencing. Also, the use of different statistical tests, both for the evaluation of the resolution of ambiguities and for the adjustment, have enabled greater clearness in analyzing the results, which allow that unsuitable observations may be eliminated.

Technical and economic evaluation of different types of control of Brevipalpus phoenicis (Acari: Tenuipalpidae) in citrus leprosies management

The objective of this work was to evaluate the effect of acaricide applications and pruning of symptomatic branches in citrus leprosis management in Brazil. It was conducted in an orange plantation of the 'Pera' variety, grafted onto the 'Cleopatra' tangerine, in two seasons (2006-2007 and 2007-2008). The experimental design was randomized blocks in a factorial scheme consisting of the following factors: (A) acaricide, in three levels: spirodiclofen and cyhexatin applied in rotation, lime sulphur; no acaricides; (B) pruning to remove branches that showed symptoms of leprosis, with two levels: with pruning, without pruning. We carried out periodic assessments of Brevipalpus phoenicis (Geijskes) populations (vector of the leprosis virus), leprosis incidence and severity, fruit yield, and the economic feasibility of the applied strategies. Based on the results, we concluded that spirodiclofen and cyhexatin were more effective than lime sulphur in B. phoenicis control. Control with lime sulphur required more applications than spirodiclofen and cyhexatin in rotation, making it more expensive. Pruning of symptomatic branches used in isolation was not sufficiently effective to control leprosis and significantly increased control costs. Profits were higher when the control involved sprayings of spirodiclofen and cyhexatin in alternation, with or without pruning.

Fatores que influenciam a qualidade de vida de pessoas com epilepsia

Epilepsy is a chronic disorder that impairs life quality (LQ) and interferes in emotional, personal, social and family relationship aspects. This study evaluated 165 people with epilepsy diagnosis, ranging from 18 to 75 years old (M=41,28; SD= 13,26), by means of the QQV-65 (Life Quality Questionnaire with 65 questions) and investigated the association between the questionnaire scores and the disease features, comparing patients who showed refrectory seizures with patients with partially controled seizures. There was no difference in relation to the two groups regarding the LQ factor. The QQV-65 emotional factor was the most affected in both groups, since the estimated mean z-escore was 51,0±14,4 for Group I and 49,9±14,7 for Group II. Regarding the type of crisis, the analysis of variance (ANOVA) revealed that Health was the only factor in QQV-65 that showed a statistically significant difference between the z-scores (P = 0.024). However, for the frequency of epileptic seizures, except Health (P = 0.185), other factors QQV-65 proved to be related in a statistically significant way (P> 0.05). The research demonstrated that seizure control perception is quite important in the evaluation of life quality in all its aspects (health, body, society, emotion, locus of control, self-concept and cognition).

Biological control of Bradysia matogrossensis (Diptera : Sciaridae) in mushroom cultivation with predatory mites

Larvae of Sciaridae flies (Diptera) cause considerable damage to the mushroom Agaricus blazei (Murrill) ss. Heinemann in Brazil. Brazilian growers have had considerable difficulties in controlling this pest. The objective of this work was to test the effect of the predatory Laelapidae mite Stratiolaelaps scimitus (Womersley) as a control agent of Bradysia matogrossensis (Lane) in cultures of A. blazei. The work corresponded to an evaluation of the efficiency of that predator when released in boxes containing each about 15 L of commercial mushroom compost naturally infested with the pest. The results showed a significant effect of that predator on the population of B. matogrossensis. The release of either 665 or 1330 S. scimitus per box significantly reduced the pest population to levels that, according to grower's experience, apparently could not cause considerable damage. The positive results obtained warrant the conduction of complementary studies to determine the lowest rates of the predator that could still produce acceptable levels of control.

Control charts for monitoring the mean vector and the covariance matrix of bivariate processes

In this article, we propose new control charts for monitoring the mean vector and the covariance matrix of bivariate processes. The traditional tools used for this purpose are the T (2) and the |S| charts. However, these charts have two drawbacks: (1) the T (2) and the |S| statistics are not easy to compute, and (2) after a signal, they do not distinguish the variable affected by the assignable cause. As an alternative to (1), we propose the MVMAX chart, which only requires the computation of sample means and sample variances. As an alternative to (2), we propose the joint use of two charts based on the non-central chi-square statistic (NCS statistic), named as the NCS charts. Once the NCS charts signal, the user can immediately identify the out-of-control variable. In general, the synthetic MVMAX chart is faster than the NCS charts and the joint T (2) and |S| charts in signaling processes disturbances.
