PROJETO PILOTO SANTA FÉ: ORGANIZAÇÃO RURAL E EXTENSÃO UNIVERSITÁRIA

The pilot project began in 1988 as a result of a request made by the community of Santa Fe to the Federal University of Goias, in order to collaborate with community development specially to assist the Association of Small Rural Producers, founded that year, as well as The Women’s Association in existence since 1979. The main objective of this extension project of the University, in partnership with the community, is the improvement of the quality of life of the population of Santa Fe de Goias. It is a region characterized by a high concentration of land ownership, by the increase of large land holdings and by the gradual disappearance of small land holdings. The university participates through the Department of Rural Economy - in various ways: making projects to raise money [CIMADE (A French ecumenical organization), FUNDEC, Banco do Brasil, the Government of the State of Goias and others]; organizing requested training courses; making trips to other communities in order to share experiences doing market research; seeking alternatives for the buying of input and selling of output; making budgets, rendering of accounts, writing letters, reports and evaluations, etc. What stands out here is our concern to never dictate the way but to show alternatives, discuss them with the associates and always follow their decision. It is an action of educational dialogue and not imposition. KEY-WORDS: Rural development; rural organization; university extension.
Lamina Cribrosa Defects and Optic Disc Morphology in Primary Open Angle Glaucoma with High Myopia

PURPOSE
To investigate whether lamina cribrosa (LC) defects are associated with optic disc morphology in primary open angle glaucoma (POAG) eyes with high myopia.


METHODS
A total of 129 POAG patients and 55 age-matched control subjects with high myopia were evaluated. Three-dimensional scan images obtained by swept source optical coherence tomography were used to detect LC defects. Radial B-scans and infrared images obtained by spectral domain optical coherence tomography were used to measure β-peripapillary atrophy (PPA) lengths with and without Bruch's membrane (BM) (temporal, nasal, superior, and inferior), tilt angle (vertical and horizontal), and disc diameter (transverse and longitudinal). Peripapillary intrachoroidal cavitations (PICCs), disc area, ovality index, and cyclotorsion of the optic disc were analyzed as well.


RESULTS
LC defects were found in 70 of 129 (54.2%) POAG eyes and 1 of 55 (1.8%) control eyes (P < 0.001). Age, sex, spherical equivalent, axial length, intraocular pressure, and central corneal thickness were not significantly different among POAG eyes with LC defects, POAG eyes without LC defects, and control eyes. Temporal PPA lengths without BM in all three groups correlated significantly with vertical and horizontal tilt angles, although no PPA length with BM correlated significantly with any tilt angle. PICCs were detected more frequently in POAG eyes with LC defects than those without LC defects (P = 0.01) and control eyes (P = 0.02). POAG eyes with LC defects showed a smaller ovality index (P = 0.004), longer temporal PPA without BM (P < 0.001), and larger vertical/horizontal tilt angles (vertical, P < 0.001; horizontal, P = 0.01), and transverse diameter (P = 0.01). In multivariate analysis for the presence of LC defects, presence of POAG (P < 0.001) and vertical tilt angle (P < 0.001) were identified as significant.


CONCLUSIONS
The presence of LC defects was associated with myopic optic disc morphology in POAG eyes with high myopia.
Microbial fuel cell as a biosensor and a power source for flora health monitoring

Microbial Fuel Cells are a promising technology for many different applications like wastewater treatment and energy supply system for monitoring hostile environments. In this article, we discuss and analyze the possibility to use jointly a small scale MFC as an energy source and a biosensor to monitor the health of the plants, with an embedded wireless sensor node. We present the prototype of the MFC and the embedded system powered by the electric energy generated by bacteria. The rate of energy generation is used as a feedback on plant's health state. Finally, we demonstrate that the amount of scavenged energy is sufficient to power on even some external sensors embedded in the wireless node.

The study on mat with hardness and elasticity for minimizing fatigue at various qork conditions

Method In order to identify the changes in the body the experiment was conducted by maintaining the standing posture for two hours by using three sorts of shoes state and four sorts of mats as an object of 9 test subjects. The Mat used in the experiment was designed on the basis of Elasticity 15% and 35%, Hardness 25Hs and 45Hs. As to the state of shoes, the experiment was progressed by dividing into three sorts of working environment: bare foot, wearing safety shoes and wearing slippers. The measuring of EMG was executed as an object of Erector Spinae, Rectus Femoris, Vastus Lateralis, Tibialis Anterior and Gastrocnemius Medialis. And, the Circumference of Leg, the circumference of crus was measured based on each projecting point of calf, and the circumference of thigh based on the center point of thigh. Results The results showed that the elasticity, hardness, and interaction between elasticity and hardness have significant differences at the Erector Spinae, Rectus Femoris with barefoot (p<0.05). The elasticity, hardness, and interaction between elasticity and hardness have significant differences at the Rectus Femoris, Vastus Lateralis with safety shoes (p<0.05). The elasticity, hardness, and interaction between elasticity and hardness have significant differences at the Rectus Femoris with slippers (p<0.05).
Research Report: Empirical Test of an EDI Adoption Model

This paper is the first test of a parsimonious model that posits three factors as determinants of the adoption of electronic data interchange (EDI): readiness, perceived benefits, and external pressure. To construct the model, we identified and organized the factors that were found to be influential in prior EDI research. By testing all these factors together in one model, we are able to investigate their relative contributions to EDI adoption decisions. Senior purchasing managers, chosen for their experience with EDI and proximity to the EDI adoption decision, were surveyed and their responses analyzed using structural equation modeling. All three determinants were found to be significant predictors of intent to adopt EDI, with external pressure and readiness being considerably more important than perceived benefits. We show that the constructs in this model can be categorized into three levels: technological, organizational, and interorganizational. We hypothesize that these categories of influence will continue to be determinants of the adoption of other emerging forms of interorganizational systems (IOS). 2
On Remote Real-time Communication between MATLAB and PLC Based on OPC Technology

Aiming at the communication between MATLAB and PLC, the paper presents a method of implementing remote real-time communication based on OPC (OLE for process control) on the Ethernet. It analyzed the principle of remote real-time communication between MATLAB and PLC and designed a remote real-time communication test system consisting of MATLAB, Ethernet and S7-300 PLC. The author realized the S7-300 PLC hardware configuration, OPC server configuration, configuration variable and real-time data exchange between MATLAB and S7-300 PLC by using MATLAB OPC toolbox, and gave out the details of procedure and program. The test results indicate that the function of exchanging remote real-time data can be attained between MATLAB and S7-300 PLC through OPC server, and prove that it is an effective and feasible method to realize the real-time remote communication between MATLAB and PLC. The proposed method can be used to realize data process and advanced control in industrial to improve the quality of control.

We write down the potentials and hidden symmetry generators of these systems, in terms of ambient Euclidean space.
Platform switch and dental implants: A meta-analysis.

OBJECTIVES
To test the null hypothesis of no difference in the implant failure rates, marginal bone loss (MBL) and postoperative infection in patients who received platform-switched implants or platform-matched implants, against the alternative hypothesis of a difference.


DATA
Main search terms used in combination: dental implant, oral implant, platform switch, switched platform, platform mismatch, and dental implant-abutment design.


SOURCES
An electronic search without time or language restrictions was undertaken in December/2014 in PubMed/Medline, Web of Science, Cochrane Oral Health Group Trials Register plus hand-searching.


STUDY SELECTION
Eligibility criteria included clinical human studies, either randomized or not.


CONCLUSIONS
Twenty-eight publications were included, with a total of 1216 platform-switched implants (16 failures; 1.32%) and 1157 platform-matched implants (13 failures; 1.12%). There was less MBL loss at implants with platform-switching than at implants with platform-matching (mean difference -0.29, 95% CI -0.38 to -0.19; P<0.00001). An increase of the mean difference of MBL between the procedures was observed with the increase in the follow-up time (P=0.001) and with the increase of the mismatch between the implant platform and the abutment (P=0.001). Due to lack of satisfactory information, meta-analyses for the outcomes 'implant failure' and 'postoperative infection' were not performed. The results of the present review should be interpreted with caution due to the presence of uncontrolled confounding factors in the included studies, most of them with short follow-up periods.


CLINICAL SIGNIFICANCE
The question whether platform-matched implants are more at risk for failure and loose more marginal bone than platform-switched implants has received increasing attention in the last years. As the philosophies of treatment alter over time, a periodic review of the different concepts is necessary to refine techniques and eliminate unnecessary procedures, forming a basis for optimum treatment.
Salting-out assisted liquid-liquid extraction with the aid of experimental design for determination of benzimidazole fungicides in high salinity samples by high-performance liquid chromatography.

A novel method for the simultaneous separation and determination of four benzimidazole fungicides (i.e., carbendazim, fuberidazole, thiophanate-methyl and thiophanate) in high salinity samples was developed by using salting-out assisted liquid-liquid extraction (SALLE) via water-miscible acetonitrile as the extractant coupled with high-performance liquid chromatography. Box-Behnken design and response surface were employed to assist the optimization of SALLE conditions, including volume of salting-out solvent, the pH of sample solution and salting-out solvent as variable factors. The optimal salting-out parameters were obtained as follows: 2 mL of acetonitrile was added to 2 mL of sample solution with pH=4 and then 2 mL salting-out solvent containing 5 mol L(-1) sodium chloride at a pH of 7 was added to the solution for extraction. This procedure afforded a convenient and cost-saving operation with good cleanup ability for the benzimidazole fungicides, such as good linear relationships (R>0.996) between peak area and concentration from 2.5 ng mL(-1) to 500 ng mL(-1), low limits of detection between 0.14 ng mL(-1) and 0.38 ng mL(-1) and the intra-day precisions of retention time below 1.0%. The method recoveries obtained at fortified three concentrations for three seawater samples ranged from 60.4% to 99.1%. The simple, rapid and eco-benign SALLE based method proved potentially applicable for trace benzimidazole fungicides analysis in high salinity samples.
Chilling injury in peach and nectarine

Peaches and nectarines ripen and deteriorate quickly at ambient temperature. Cold storage is used to slow these processes and decay development. However, low temperature disorders, chilling injury classified as internal breakdown, limit the storage life of peaches and nectarines under refrigeration. The onset of chilling injury symptoms determines the postharvest storage/shipping potential because their development reduces consumer acceptance. Chilling injury is genetically influenced and triggered by a combination of storage temperature and storage period. It manifests itself as fruit that are dry and have a mealy or woolly texture (mealiness or woolliness), or hard textured fruit with no juice (leatheriness), fruit with flesh or pit cavity browning (internal browning), or with flesh bleeding (internal reddening). In this review, we describe what is known about the etiology of each of these types of chilling injury symptoms as well as the biochemical processes in the fruit tissue responsible for their development. We also report on preand postharvest manipulations or treatments that can affect the time of appearance or severity of chilling injury symptoms.
The German cervical cancer screening model: development and validation of a decision-analytic model for cervical cancer screening in Germany.

BACKGROUND
We sought to develop and validate a decision-analytic model for the natural history of cervical cancer for the German health care context and to apply it to cervical cancer screening.


METHODS
We developed a Markov model for the natural history of cervical cancer and cervical cancer screening in the German health care context. The model reflects current German practice standards for screening, diagnostic follow-up and treatment regarding cervical cancer and its precursors. Data for disease progression and cervical cancer survival were obtained from the literature and German cancer registries. Accuracy of Papanicolaou (Pap) testing was based on meta-analyses. We performed internal and external model validation using observed epidemiological data for unscreened women from different German cancer registries. The model predicts life expectancy, incidence of detected cervical cancer cases, lifetime cervical cancer risks and mortality.


RESULTS
The model predicted a lifetime cervical cancer risk of 3.0% and a lifetime cervical cancer mortality of 1.0%, with a peak cancer incidence of 84/100,000 at age 51 years. These results were similar to observed data from German cancer registries, German literature data and results from other international models. Based on our model, annual Pap screening could prevent 98.7% of diagnosed cancer cases and 99.6% of deaths due to cervical cancer in women completely adherent to screening and compliant to treatment. Extending the screening interval from 1 year to 2, 3 or 5 years resulted in reduced screening effectiveness.


CONCLUSIONS
This model provides a tool for evaluating the long-term effectiveness of different cervical cancer screening tests and strategies.
Comprehensive whole-genome and candidate gene analysis for response to statin therapy in the Treating to New Targets (TNT) cohort.

BACKGROUND
Statins are effective at lowering low-density lipoprotein cholesterol and reducing risk of cardiovascular disease, but variability in response is not well understood. To address this, 5745 individuals from the Treating to New Targets (TNT) trial were genotyped in a combination of a whole-genome and candidate gene approach to identify associations with response to atorvastatin treatment.


METHODS AND RESULTS
A total of 291 988 single-nucleotide polymorphisms (SNPs) from 1984 individuals were analyzed for association with statin response, followed by genotyping top hits in 3761 additional individuals. None was significant at the whole-genome level in either the initial or follow-up test sets for association with low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, or triglyceride response. In addition to the whole-genome platform, 23 candidate genes previously associated with statin response were analyzed in these 5745 individuals. Three SNPs in apoE were most highly associated with low-density lipoprotein cholesterol response, followed by 1 in PCSK9 with a similar effect size. At the candidate gene level, SNPs in HMGCR were also significant though the effect was less than with those in apoE and PCSK9. rs7412/apoE had the most significant association (P=6x10(-30)), and its high significance in the whole-genome study (P=4x10(-9)) confirmed the suitability of this population for detecting effects. Age and gender were found to influence low-density lipoprotein cholesterol response to a similar extent as the most pronounced genetic effects.


CONCLUSIONS
Among SNPs tested with an allele frequency of at least 5%, only SNPs in apoE are found to influence statin response significantly. Less frequent variants in PCSK9 and smaller effect sizes in SNPs in HMGCR were also revealed.
A 3GHz-10GHz common gate ultrawideband low noise amplifier

In this paper, a 3GHz-10GHz ultra wideband (UWB) low noise amplifier (LNA) typology is proposed. The broadband matching and the flat gain are two important factors for the broadband circuits. Besides those factors, the minimal noise figure (NF), good linearity, and the lower power consumption are also desired. The common gate input stage with the 3rd order Butterworth filter configuration is used in the proposed LNA to achieve the broadband input matching. The flat gain of the LNA is achieved by the combination of the inductor peaking load and the shunt inductor insertion between the cascade stages of LNA. The LNA is designed in the standard 0.18mum CMOS technology. It achieved 14.5~15.3dB gain from 3GHz to 10GHz and 3.43dBm IIP3 in 5GHz, operates from 1.8V power supply, and dissipates 4.3mW without the output buffer
Abscess Formation Following Spilled Gallstones During Laparoscopic Cholecystectomy


OBJECTIVE
Our purpose was to report the occurrence of abscess following spilled gallstones during laparoscopic cholecystectomy as experienced at Good Samaritan Hospital, and to compare it to the experience of other institutions in order to identify the incidence, characteristics and possible risk factors for the development of this complication.


METHODS
Four case reports of abscess following spilled gallstones during laparoscopic cholecystectomy are presented. The English literature was reviewed, and characteristics of the case reports found in the literature were compared.


RESULTS
In four years at this institution, four reports of abscess formation following laparoscopic cholecystectomy have been identified. Two occurred in elderly females and were located in the right flank in both. Two were in middle-aged men, both diabetic. One abscess was in the right flank and one in the right pleural space. Twenty-three cases were found in the literature. The average age was 65 years; there were 12 men and 11 women. The locations of abscess formation were trocar sites (most common), right subphrenic space, right flank or retroperitoneum, and pelvis. The average time to presentation was 4-5 months (range 4 days-12 months).


CONCLUSIONS
Abscess formation following spilled gallstones during laparoscopic cholecystectomy occurs infrequently, but can be debilitating and require more than one procedure. The older population appears to be at greater risk. Future prospective studies of patients who undergo laparoscopic cholecystectomy are needed to more accurately determine the incidence of this complication and to identify the population at risk.
Robust feature extraction based on an asymmetric level-dependent auditory filterbank and a subband spectrum enhancement technique

In this paper we introduce a robust feature extract o , dubbed as robust compressive gammachirp filterbank cepstral coefficients (RCGCC) , based on an asymmetric and level-dependent compressive gammachirp filterbank a nd a sigmoid shape weighting rule for the enhancement of speech spectra in the audito ry domain. The goal of this work is to improve the robustness of speech recognition system s in additive noise and real-time reverberant environments. As a post processing sche me we employ a short-time feature normalization technique called short-time cepstral mean and scale normalization (STCMSN), which, by adjusting the scale and mean of cepstral features, reduces the difference of cepstra between the training and test environments. For performance evaluation, in the context of speech recognition, o f the proposed feature extractor we use the standard noisy AURORA-2 connected digit corpus, the meeting recorder digits (MRDs) subset of the AURORA-5 corpus, and the AUROR A-4 LVCSR corpus, which represent additive noise, reverberant acoustic cond iti s and additive noise as well as different microphone channel conditions, respective ly. The ETSI advanced front-end (ETSI-AFE), the recently proposed power normalized cepstral coefficients (PNCC), conventional MFCC and PLP features are used for com parison purposes. Experimental speech recognition results demonstrate that the pro posed method is robust against both additive and reverberant environments. The proposed m thod provides comparable results to that of the ETSI-AFE and PNCC on the AUR ORA-2 as well as AURORA-4 corpora and provides considerable improvements with respect to the other feature extractors on the AURORA-5 corpus.
