Client objectives in a building project are to build within the budget and estimated construction period and being satisfied with the quality of the project. The ability of the procurement methods in achieving these objectives does influence the client to choose any to implement the project. The performance of two of such procurement methods: the traditional contracting and design-build against client objectives were determined using data set of 53 traditional contracts and 15 design-build projects gathered through a questionnaire survey administered unto respondents in three locations in Nigeria. Time overrun, cost overrun and clients’ satisfaction with quality standard were used as basis for comparison. Analysis showed that, the mean cost overrun, and time overrun for design-build were 21.4% and 36.8% respectively as compared with 42.6% and 135.6% for traditional contracting projects. As for quality standard, 78% of design-build clients were satisfied with their projects as compared with 51% for traditional contracting. The overall conclusion is that both methods involve overrun but design-build performed better. Santrauka Užsakovo, vykdančio statybos projektą tikslai – pastatyti statini neviršijant numatyto biudžeto, statybos trukmės ir būti patenkintam projekto kokybe. Pirkimų metodų galimybė pasiekti šiuos tikslus veikia užsakovo sprendimą kurį iš šių metodų pasirinkti ir igyvendinti. Naudojant 53 tradicinių statybos rangos sutarčių ir 15 projektavimo bei statybos sutarčiųduomenis, surinktus apklausų būdu trijuose Nigerijos regionuose, buvo nustatyti du statybos darbų pirkimo vykdymo bū- dai: tradicinis statybos darbų pirkimas ir projektavimo bei statybos pirkimas, atsižvelgiant į užsakovo tikslus. Statybos trukmės viršijimas, kainos viršijimas, pasitenkinimas atliktų darbų kokybe buvo naudojami kaip palyginimų pagrindas. Atlikta analizė parodė, kad vidutinis trukmės ir kainos viršijimas projektavimo ir statybos sutartyse buvo atitinkamai21,4% ir 36,8%, o tradicinėse statybos rangos sutartyse – 42,6% ir 135,6%. 78% projektavimo bei statybos užsakovųbuvo patenkinti atliktų darbų kokybe, o darbus vykdant pagal tradicines sutartis, patenkintųjųdarbų kokybe buvo 51%. Bendra išvada yra ta, kad abiem metodais buvo viršyta trukmė ir kaina, bet taikant projektavimo bei statybos metodą šie rodikliai yra geresni.

Background. We evaluated the pharmacodynamic interaction of the combination of pancuronium and Rocuronium by analyzing time-response relationship, quality of intubating conditions, changes in the hemodynamics, and cost effectiveness as compared to individual drugs. Methods. Sixty patients in the ASA-I category received either 10 ml of 0.9 mg/kg rocuronium (R) plus 10 ml of saline or 10 ml of 0.1 mg/kg pancuronium (P) plus 10 ml of saline or a combination (C) of 10 ml of 0.45 mg/kg R plus 10 ml of 0.05 mg/kg P according to randomization list. Neuromuscular function was measured up to maximal suppression of twitch height. Results. The mean times (sec) taken for twitch height to decrease to 50% of baseline in R, P, and C were 36.84 ± 2.54, 74.60 ± 4.94, and 40.81 ± 2.34, respectively. The mean cost of intubation per patient was 316.71 ± 83.61 INR in group R, 52.30 ± 14.94 INR in group P, and 93.33 ± 20.65 INR in group C. Conclusions. The combination of P and R provides rapid and smooth intubation with minimal hemodynamic changes at a reasonably priced cost.

Testing is very essential in Data warehouse systems for decision making because the accuracy, validation and correctness of data depends on it. By looking to the characteristics and complexity of iData iwarehouse, iin ithis ipaper, iwe ihave itried ito ishow the scope of automated testing in assuring ibest data iwarehouse isolutions. Firstly, we developed a data set generator for creating synthetic but near to real data; then in isynthesized idata, with ithe help of hand icoded Extraction, Transformation and Loading (ETL) routine, anomalies are classified. For the quality assurance of data for a Data warehouse and to give the idea of how important the iExtraction, iTransformation iand iLoading iis, some very important test cases were identified. After that, to ensure the quality of data, the procedures of automated testing iwere iembedded iin ihand icoded iETL iroutine. Statistical analysis was done and it revealed a big enhancement in the quality of data with the procedures of automated testing. It enhances the fact that automated testing gives promising results in the data warehouse quality. For effective and easy maintenance of distributed data,a novel architecture was proposed. Although the desired result of this research is achieved successfully and the objectives are promising, but still there's a need to validate the results with the real life environment, as this research was done in simulated environment, which may not always give the desired results in real life environment. Hence, the overall potential of the proposed architecture can be seen until it is deployed to manage the real data which is distributed globally.

Introduction The incidence of deep neck space infection (DNSI) is rising and appears to be related to falling rates of tonsillectomy. The purpose of this study was to assess demographics of patients presenting with DNSI and the financial burden to the National Health Service (NHS). Methods Data were collected retrospectively on patients aged over 16 years admitted to NHS Greater Glasgow and Clyde with DNSI between 2012 and 2016. Demographics, aetiology and use of hospital resources were reviewed. The cost of hospital admissions was calculated using data from NHS Scotland’s Information Services Division, the local diagnostics division and the British National Formulary. Results Seventy-four patients were admitted with DNSI during the study period. Forty (54%) were male. The mean age was 44.0 years (range: 16–86 years). The most frequent source of infection was the tonsil (n=30, 40.5%). The most common infective organism was Streptococcus constellatus (n=9, 12.2%). The mean length of stay was 11 days. Fifty-five patients (74.3%) required operative intervention. The mean cost of admission per patient was £5,700 (range: £332–£46,700). Conclusions This study highlights the high cost burden of DNSI to the NHS. The incidence of DNSI in Glasgow has risen over the study period; contributing factors may include the reduced tonsillectomy rate and a reduction in antibiotic prescribing. As the incidence of DNSI continues to rise, there will be an increase in cost to the NHS, which must be planned for.

Educational Indicators

Educational indicators are metrics that assist in assessing the quality of the educational system. They are often associated with economic and social factors suggested to contribute to good school performance, however there is no consensus on the impact of these factors. The main objective of this work was to evaluate the factors related to school performance. Using a data set composed by Brazilian schools’ performance (IDEB), socioeconomic and school structure variables, we generated different models. The non-linear model predicted the best performance, measured by the error and determination coefficient metrics. The heterogeneity of the importance of the variable between school cycles and regions of the country was detected, this effect may contribute to the development of public educational policies.

Using Data

Space-based remote-sensing instruments providing atmospheric measurements have different time and space resolutions, and coverage. This makes the direct comparison of the measurements very difficult. Data assimilation has proven to be a far more powerful tool than simple interpolation techniques to create three-dimensional analyzed fields for a given data set. In this paper, we describe how the assimilation of ozone data from the Odin/SMR instrument can be used to assess its precisions and biases against other ozone-measuring instruments. To assess the quality of Odin/SMR ozone retrievals by MOLIERE-5 against ozonesondes, Envisat/MIPAS, Earth Probe/TOMS, and UARS/HALOE data, we use a three-dimensional variational assimilation scheme applied to the Météo-France MOCAGE chemistry transport model. The MOCAGE-PALM assimilation system has been already used by Météo-France and CERFACS to analyse the Envisat/MIPAS data for the ASSET intercomparison exercise. We have further developed and calibrated the configuration of this system to better account for the Odin/SMR ozone profiles. The upgraded system is used to assimilate the Odin/SMR ozone during the August 2003 – November 2003 period and intercomparisons are made with the other ozone measuring techniques. The Odin/SMR analysis and the other ozone data sets are in good agreement at mid and high latitudes, while in the lower tropical stratosphere, we found a positive bias of the Odin/SMR, Envisat/MIPAS, and Earth Probe/TOMS data compared to measurements from UARS/HALOE and ozonesondes. The precision of Odin/SMR ozone retrievals in terms of standard deviation is about 20% in the tropics, below 10% at high southern latitudes, and below 5% at high northern latitudes.

AbstractA technique for correcting radar radial velocity Vr in airborne, nadir-pointing radar data using the surface of Earth as a reference is proposed and tested. Operating airborne Doppler radars requires correcting the radial velocity for platform motion. This can be accomplished with accurate beam-pointing and platform motion measurements. However, there are often residual pointing errors due to drift in inertial navigation systems (INS) and/or errors in platform-relative pointing. The technique proposed here takes advantage of the fact that the surface is stationary and the mean of the measured Vr at the surface should be 0 m s−1. Therefore, if a good estimate of the mean is made, it can be subtracted from the measured Vr to correct for errors due to residual pointing errors. The data contain many independent deviations from 0 m s−1 due to various causes, including measurement variance and large deviations due to surface features. These deviations must be filtered out of before the surface reference can be applied to correct the Vr data. A two-step filtering process was developed and tested. The first step removes large deviations in and the second step removes the measurement noise. The technique was examined using data from three field campaigns and was found to improve the quality of Vr in all cases. The Vr bias was removed and the variance was substantially reduced. The approach is generally applicable to nadir-pointing airborne radar data.

Abstract Background To estimate the health care resource utilization, costs, and impact on quality of life (QoL) of herpes zoster (HZ) and postherpetic neuralgia (PHN) in adults aged ≥50 years in Italy. Methods This was a prospective, observational, multicenter, community physician–based surveillance study (NCT01772160) in Italy. Health-related QoL data were collected using the EuroQoL-5 Dimension (EQ-5D) and Zoster Brief Pain Inventory (ZBPI) questionnaires. Both questionnaires were assessed at days 0 (HZ rash onset), 15, 30, 60, and 90 for all patients, and monthly thereafter for patients who developed PHN. Resource utilization was recorded for 3 months post–HZ onset and 9 months for PHN patients. Costs from both payer and societal perspectives were estimated and were composed of direct medical costs (general practitioner/specialist visits, procedures, hospitalizations, medications), work loss by patient/caregiver, and transport costs. Results A total of 391 patients with HZ were included, of whom 40 developed PHN. The mean ZBPI worst pain score was 5.7 at day 0, reducing to 2.6 at day 30 and 0.7 by day 90. Patients with PHN had a mean worst pain score of 5.7 at day 90. We estimated an overall disutility associated with HZ of 0.134. The mean cost per HZ patient from a payer/societal perspective was €153/€298, respectively, and the mean cost per HZ patients who developed PHN was €176/€426, respectively. Conclusions HZ is associated with impaired QoL and substantial health care resource use, highlighting the need for preventive strategies. This could reduce the disease burden for the patient and health care system. ClinicalTrials.gov study registry NCT01772160.

Semen was collected from four rams, using artificial vagina and viability%, motility% and plasma membrane integrity% were measured. Fresh ejaculates (n = 32) were separated by modified swim-up separation using modified human tubal fluid medium. Four fractions of supernatant were collected at 15-minute intervals. The mean volume, mass activity, concentration, motility%, viability%, normal morphology and membrane integrity% (HOST +ve) of fresh semen were 1.0 ± 0.14, 4.1 ± 0.1 × 109 spermatozoa/ml, 85.0 ± 1.3, 89.4 ± 1.0, 85.5 ± 0.7, 84.7 ± 0.5 respectively. There was no significant (P>0.05) difference in fresh semen quality parameters between rams. The motility%, viability% and HOST +ve % of first, second, third and fourth fractions were 53.4 ± 0.5, 68.2 ± 0.3, 74.8 ± 0.3 and 65.5 ± 0.4; 55.5 ± 0.4, 66.2 ± 0.4, 74.5 ± 0.3 and 73.6 ± 0.3 and 66.7 ± 0.5, 66.8 ± 0.5, 65.2 ± 0.4 and 74.7 ± 0.5 respectively. The motility%, viability% and membrane integrity% of separated semen samples differed significantly (P<0.05) between four fractions. The mean motility% and viability% were significantly higher (P<0.05) in third fraction (74.8 ± 0.3%), whereas the mean HOST +ve% was significantly higher (P<0.05) in fourth fraction (74.7 ± 0.5). All quality parameters of separated spermatozoa were significantly (P<0.05) lower than that of fresh semen. The pregnancy rates were higher with fresh semen (71%) in comparison to that of separated sample (57%).Bangl. vet. 2016. Vol. 33, No. 2, 62-70
