Identificação e priorização dos fatores críticos de sucesso na implantação de fábrica digital

A Digital Factory is a concept which improves the collaboration among product development processes. Despite the benefits brought by this concept, failures may occur in its implementation. This paper aims to present the Critical Success Factors in the implementation of a Digital Factory project in a Brazilian company. These factors were identified by an exploratory survey on the implementation of Enterprise Resource Planning and Product Lifecycle Management among other systems. Following this identification, the factors were prioritized using the Delphi Method and the Analytic Hierarchy Process; this evaluation was carried out by professionals from enterprises which implement Digital Factory projects, in Brazil and abroad. Nine factors were identified. The five main priorities were: Continuous Support and Commitment from Top Management; Comprehensive Business Reengineering; Skilled and Experienced Partners; Participation and Commitment of Users; and Appropriate Role of the Project Manager.

Valor preditivo do potencial de implantação embrionário pela análise do perfil químico de meios de cultivo por espectrometria de massas (ESI-Q-ToF)

Objective: This case-control study analyzed mass spectrometry fingerprinting patterns of culture media samples used for embryo culture to predict embryo implantation. Methods: The culture medium harvested after embryo transfer of 22 embryos from 13 patients was used for the experiments. After embryo transfer, the remaining culture media were collected and samples were split in positive (n=8) and negative (n=14) implantation groups according to implantation outcomes (100% or 0% of implantation). Samples were individually diluted and injected directly to the Electrospray ionization (ESI) MS coupled to a Quadrupole Time-of-flight MS (Q-ToF-MS).Ions relative intensities of each spectrum were considered. Data analysis was conducted in MatLab 7.0 version using Partial Least Squares - Discriminant Analysis toolbox. Results: There were 3027 observed ions at 100% and 0% implantation groups by ESI-Q-ToF-MS. The statistical model could categorize the samples in two clusters, based on their positive and negative implantation outcomes. Less intense ions present in the mass spectra with statistical significance have contributed to the major differences to group distinction. Conclusions: Positive and negative implantation embryos showed a specific biochemical pattern present in culture media, which could be detected as a fast, simple and non-invasive way. This biochemical profile could help the selection of the most viable embryo, improving single embryo transfer and thus eliminating the risk and undesirable outcomes of multiple pregnancies. © Todos os direitos reservados a SBRA - Sociedade Brasileira de Reprodução Assistida.

Tamanho de amostra e estimativa de custo em levantamento epidemiológico de cárie dentária

This study aimed to analyze how the prevalence and the distribution of dental caries influence the sample size in epidemiological surveys, and how much are the costs. Secondary data of oral health surveys in 12-year-old schoolchildren from Bauru in 1976, 1984, 1990, 1994, and 2001, and from Piracicaba in 2001 and 2005 were studied. Sample sizes were estimated taking into account the mean DMFT and standard deviation of each survey, establishing sampling errors of 1%, 2%, 5%, and 10%. Costs were estimated considering permanent material, consumption material and human resources. The sample size in both towns needed to be increased, ranging from 119 in 1976 to 1,118 in 2001 in Bauru, and from 954 in 2001 to 1,252 in 2005 in Piracicaba, when a sampling error of 10% was considered. The cost of dental caries surveys was verified considering different sampling errors. This cost depends on how acceptable is the margin of difference between the true mean and the one found in the survey. In conclusion, the reduction in the prevalence of dental caries has determined the need for increase in sample size and in costs for conducting the surveys.

Avaliação de usuários da atenção básica sobre a implantação de protocolo de assistência integral odontológica

Objective: To evaluate the perception of basic attention healthcare users as to the implantation of the Integral Dental Assistance Protocol (PAIO, in Portuguese) and the effect of this program on the oral health condition, oral hygiene, access to and resolubility of the service, in a public basic health unit of João Pessoa-PB. Method: The sample was composed of 32 volunteers, for whom a sixphase intervention was programed: diagnosis of dental needs; resolution of urgencies; restorative interventions; application of promotional measures; evaluation of the health level obtained; and periodic follow-up visits. Data were collected by means of a semistructured interview and a questionnaire, applied before and after PAIO implantation. The interviews were transcribed and analyzed according to the content analysis technique. The effect of PAIO implantation was evaluated by using an increasing scoring system ranging from 1 to 10. The Wilcoxon test was applied with a confidence level of 95%. Results: For the participants that attended the PAIO (n=20), the program contributed to improve oral health condition (100%) and knowledge (100%). The users reported satisfaction (n=12) and had a positive evaluation (n=12), achieved by means of the improvement of oral health condition (n=8), faster and easier access to treatment (n=7), scheduling of dental appoints and warrant of being treated (n=6), welcoming (n=5), motivation for oral care (n=5), and perspective of continuity of PAIO (n=6). The initial evaluation of the users received scores between 5.7 and 7.6. After PAIO implantation, the users' perception was improved (p<0.01), with scores between 9.6 and 9.9. Conclusion: According to the users, the implantation of PAIO contributed to the qualification of health service and oral health care, being a favorable aspect to increase the access to and resolubility of the service.

Fontes de carbono de baixo custo para a produção de xilanase termoestável por aspergillus niger

A strain of the flamentous fungus Aspergillus niger was isolated and shown to possess extracellular xylanolytic activity. These enzymes have biotechnological potential and can be employed in various industries. This fungus produced its highest xylanase activity in a medium made up of 0.1% CaCO3, 0.5% NaCl, 0.1% NH4Cl, 0.5% corn steep liquor and 1% carbon source, at pH 8.0. A low-cost hemicellulose residue (powdered corncob) proved to be an excellent inducer of the A. niger xylanolytic complex. Filtration of the crude culture medium with suspended kaolin was ideal for to clarify the extract and led to partial purifcation of the xylanolytic activity. The apparent molecular mass of the xylanase was about 32.3 kDa. Maximum enzyme activity occurred at pH 5.0 and 55-60oC. Apparent Km was 10.41 ± 0.282 mg/mL and Vmax was 3.32 ± 0.053 U/mg protein, with birchwood xylan as the substrate. Activation energy was 4.55 kcal/mol and half-life of the crude enzyme at 60oC was 30 minutes. Addition of 2% glucose to the culture medium supplemented with xylan repressed xylanase production, but in the presence of xylose the enzyme production was not affected.

Programação, conexão e avaliação de psicrômetro aspirado de termopar de baixo custo em micrologger para estudos agrometeorológicos

As the psychrometric method is considered standard for the measurement of relative humidity, many studies have used aspirated thermocouple psychrometers connected to microloggers but, however, they do not detail how the aspiration of the air stream is done. However, one of the major difficulties of aspirated thermocouple psychrometers is to program and to connect it in micrologger, because specific programming and connection are requires, and still some skills in getting accurate measurements. This work aimed to provide the programming and the connection of the aspirated thermocouple psychrometer type T for the CR10X microloggers and CR23X of Campbell Scientific, evaluating the quality of measurements of temperature and air relative humidity in relation the a sensor Vaisala HMP50. The non-continuous measurements were made in the period 2006/09/04 to 2007/07/11 at Jaboticabal, SP. The air temperature measurements were similar between the Vaisala sensors and aspirated thermocouple psychrometer, but the relative humidity measurements were significantly different. The measurements obtained by the aspirated thermocouple psychrometer connected to CR10X micrologger were the most accurate. Using the programming and connection of a micro-fan to suck in the dry and moist bulbs of aspirated thermocouple psychrometer in microloggers models CR10X and CR23X, it is possible to obtain measurements of air temperature with good precision and accuracy, and measurements of air relative humidity with good precision, but accuracy is not always attainable due to the difficulties inherent to the physical processes that occur in the wet bulb, the skill in the use and maintenance of this equipment and the reservoir protection against radiative effects.
