Full textAbstract:
Reproductive toxicity testing systems are used by national and international regulatory agencies. Protocols have not been standardized between agencies or even within certain agencies. Although there have been efforts at standardization, a certain amount of the differences between testing protocols is a reflection of the needs of the particular agency. New developments in in vitro techniques might lead to new test systems, but reproductive function is dependent upon the interaction of various cells and organs that cannot presently be copied in the test tube; this makes whole-animal testing systems a necessity. The present whole-animal models used by the Food and Drug Administration include the 3 segment reproduction studies used for testing drug safety and the multigeneration studies used for food additives. The Environmental Protection Agency has adopted 2 similar versions of a 2-generation study for the Office of Pesticide Programs and the Office of Toxic Substances. The National Toxicology Program, although not a regulatory agency, has taken a prominent role in reproductive toxicity testing, test system development, and test system evaluation. A new testing system, Fertility Assessment by Continuous Breeding (FACB), is currently being studied as a cost-effective and reliable alternative test system. The FACB protocol houses male and female mice as breeding pairs and removes offspring as soon as they are born during the first 14 weeks to allow continuous mating. Each breeding pair normally has up to 5 litters, and the last litter is saved to evaluate the second generation. The efficiency, reliability, and expense of the protocol are being compared to the existing testing systems.

Full textAbstract:
Background and context: The National Screening Unit in the Ministry of Health is responsible for the safety, effectiveness, and quality of five formal screening programs in New Zealand: breast screening, cervical screening, bowel screening, newborn metabolic screening, and newborn hearing screening. Currently, each screening program has a set of standards against which performance is assessed. Each program is monitored through a range of avenues: formally reported indicators, audits, contract reporting, case reviews, etc. Aim: We aimed to review the existing monitoring across all the screening programs to: (a) Clarify what existing measures served what purpose, and for which audience (b) Review what was being captured through different monitoring avenues, to assess gaps and duplications (c) To better align our monitoring approach across all the screening programs. Strategy/Tactics: For each measure, we used a formal template to justify its existence, covering multiple aspects including rationale, lifespan, dimension of quality, screening pathway step, targets and associated evidence, thresholds for corrective action, and “owner” responsible for triggering quality improvement. We also mapped the screening program standards to various monitoring avenues to assess gaps and duplications. Program/Policy process: This process was timed to coincide with the need for developing monitoring for a new screening program (bowel screening), and revising monitoring for an established screening program undergoing a change (cervical screening switching to HPV testing as a primary screen). Outcomes: *anticipated outcomes in italics, will be completed by time of Congress* This process resulted in an overarching monitoring framework, which functions as a blueprint for screening-program-specific monitoring plans. What was learned: Screening programs have different monitoring requirements depending on what phase they are in (i.e., new versus changing versus established). Having clearly documented rationale ensures that every measure is justified and has an “evidence trail”. Having clearly documented audiences, thresholds and responsibilities for corrective action ensures that monitoring contributes to continuous quality improvement, rather than monitoring for monitoring's sake.

Full textAbstract:
Continuous monitoring and download of endotracheal tube cuff pressure for a 12-hour period were required to collect data for an ongoing program of research related to airway management of the critically ill patient. On the basis of reports from the anesthesia literature, continuous monitoring of cuff pressure via a traditional pressure transducer and monitor was identified as the best method to collect data. Although continuous pressure monitoring of many physiologic variables is routine in critical care settings, application of the technology to measurement of endotracheal tube cuff pressure has not been reported outside the operating room. The research team conducted bench testing and pilot testing in human subjects to establish feasibility, accuracy, and safety of continuous cuff pressure monitoring. Monitoring was feasible with stringent procedures applied to ensure safety. A bias of 0.5 cm H2O between continuous and intermittent measures was obtained in both in vitro and in vivo testing.

Full textAbstract:
A networked structural laboratory system NetSLab has been developed for shared use of laboratory facilities and computing resources. The NetSLab consists of a network based communication platform and a series of hybrid testing programs. In this paper, a hybrid testing program for simulating seismic responses of composite frame structures with buckling restrained braces has been developed. The entire frame structure is simplified as a multi-degree-of-freedom model and only the relationship between story shear force and story drift is considered. The hybrid testing program consists of three types of modules, namely control center, physical tester, virtual tester. Control center organizes testing procedure and handles numerical integration. Physical tester and virtual tester generate restoring forces of substructures using actual testing equipment or numerical simulation. The substructure tested can be any continuous multi-story or a single brace taken from the entire frame structure. A serial port communication method is utilized to transfer request and feedback data between physical tester and the control computer of Popwil electro-hydraulic servo system. A series of virtual and physical hybrid tests of composite frame structures with buckling restrained braces under earthquake excitations were carried out. The results validated the reliability of the testing program.

AbstractWe present a site testing program initiated at the SUMMIT station on the Greenland Ice Cap. A DIMM was mounted in the SWISS tower, 39 m above the ice level, during a period of 3 weeks in the late Arctic summer 2008. Tracking Polaris, the DIMM obtained continuous seeing measurements. The campaign was hampered by poor weather and the measured seeing was fluctuating, suggesting that the boundary layer was very unstable. However, during short periods, the un-calibrated seeing went below 0″.5, indicating that the free atmosphere seeing above Greenland is not significantly different from what is found above the Antarctic plateau.

Full textAbstract:
As higher education tends to witness drastic changes, the quality of output is highly valued, which demands continuous innovation in the teaching process, especially on assessing students’ learning outcomes from the training program’s requirements. The paper outlines the relationship between student assessment and other components in the teaching process, performance indicator (PI) for the program learning outcomes, which refers to teaching, testing and assessment activities. At the same time, the article presents the process of setting up and evaluating the achievements of students through the method of PI evaluation based on the program’s learning outcomes. The current situation is that the learning outcomes of undergraduate training programs in various universities in the country tend to be developed in a general and highly integrated manner, thus widening the gap between the learning outcomes’ requirements and the actual teaching, testing, and evaluation activities of the module/ subject.

The world of education is continuously changing. New information and communication technologies have appeared as an important component of the actual teaching/learning strategies. We arrived into a new era, called e-Learning period. Nowadays, e-Learning has become a viable alternative to traditional methods, adopted by many educational institutions, especially because of the advantages offered by the possibility of continuous training.
In Romania, these teaching/learning strategies face rapid development. This paper presents a software-tool developed in Delphi environment – PowerFee – used for periodical training and testing students via Internet. According to intern rules of the department, all students must accomplish a given number of training-tests every semester, to ensure the proper assimilation of the new information. To optimize this process, the program can be reached via local network using a user name and password. A comparison between results obtained by classical teaching/learning methods and ones achieved by modern e-Learning techniques is presented.

The measurement of deflection characteristics is a key feature in the evaluation of pavements. Deflections are used to evaluate pavement moduli, relative stiffness, load transfer, and, when used periodically, a rate of deterioration and remaining life. The comprehensive deflection testing program conducted on Runways 9L/27R and 8R/26L, both jointed concrete pavements, at the Hartsfield Atlanta International Airport is described. A heavy-weight deflectometer was used to measure deflections at discrete locations on slab interiors, transverse joints, longitudinal joints, and slab corners. A rolling dynamic deflectometer was used to measure continuous deflection profiles along three longitudinal lines on both runways. Before fall 2001, all pavement deflection testing was performed using a falling-weight deflectometer. Comparisons of the equipment, loading mechanisms, and measured deflections are presented.

Full textAbstract:
Abstract Background: Proficiency testing (PT) provides a measure of the effectiveness of laboratory quality assurance programs. Test reports are released from processes that the laboratory judges to be in conformance with quality specifications; an evaluation of unsatisfactory performance (UNSAT) by a PT provider is an unexpected outcome for the laboratory. An understanding of the root cause(s) of testing errors provides an opportunity for the continuous improvement of laboratory services. Methods: We used participant data from the New York State Department of Health PT program to characterize the quality of testing in the toxicology specialty. Outcomes from laboratory investigations into causes of UNSAT and information on quality control practices collected from all program participants were used to identify the root causes of error. Results: Two classes of error were encountered: spurious test results caused by lapses in standard operating procedures and instrument malfunctions (300 per million assays) and common-cause analytic error (7000 per million assays or 0.7% rate of UNSAT). Causes of spurious results included inaccurate mathematical correction for specimen dilution, misinterpretation of instrument codes, and instrument sampling errors. Calibration drift was most frequently cited as the common-cause analytic error. Approximately one-half of the laboratories used an allowable error for the quality control of analytical systems that exceeded the threshold error specified by manufacturers for stable instrument performance. Conclusions: The causes of spurious results suggest the need for ongoing competency testing of analysts where analyst intervention is required in an otherwise automated process, and for continued diligence in mistake-proofing instrument design. The intrinsic quality of laboratory testing is unlikely to improve until the allowable error in quality control is consistent with manufacturer specifications for stable system performance.

Background Out of school hours care (OSHC) services provide a unique opportunity to deliver early intervention programs to enhance primary school–aged children’s social, emotional, physical, and cognitive well-being; however, such programs are currently lacking. Objective This study aims to address the lack of well-being programs for children accessing OSHC services in the research literature by using participatory design (PD) to collaboratively develop and test an OSHC well-being program—the connect, promote, and protect program (CP3). Methods The study employed methods of PD, user (acceptance) testing, and iterative knowledge translation to develop a novel well-being program framework—CP3—with key stakeholders (eg, children, OSHC staff, volunteers, families, clinicians, educators, and researchers). Thematic techniques were used to interpret and translate the qualitative information obtained during the research and design cycles. Results The co-design process generated the CP3 model, which comprises a group-based mentoring approach to facilitate enhanced activities in OSHC settings. Activities are underpinned by 4 key principles of program delivery: build well-being and resilience, broaden horizons, inspire and engage, and connect communities. Conclusions To our knowledge, the CP3 program is the first co-designed well-being program developed specifically for OSHC services. This co-design process is key to ensuring local community needs—particularly those of young people accessing OSHC—are met and that these individuals are meaningfully and actively involved in all stages of the research and design process, from conception to implementation, evaluation, and continuous improvement.

Full textAbstract:
Background Smoking cessation helps extend a healthy life span and reduces medical expenses. However, the standard 12-week smoking cessation program in Japan has several notable problems. First, only 30% of participants complete this program. Second, participants may choose not to participate unless they have a strong motivation to quit smoking, such as health problems. Third, the program does not provide enough support during the period between clinical visits and after 12 weeks. Objective This study examined the efficacy of the 24-week ascure program to address the problems of accessibility and continuous support. The program combines online mentoring, over-the-counter pharmacotherapy, and a smartphone app. Methods Using a retrospective study design, we investigated data for 177 adult smokers who were enrolled in the ascure smoking cessation program between August 2017 and August 2018. The primary outcomes were continuous abstinence rates (CARs) during weeks 9-12 and weeks 21-24. To confirm smoking status, we performed salivary cotinine testing at weeks 12 and 24. We also evaluated the program adherence rate. Finally, we performed exploratory analysis to determine the factors associated with continuous abstinence at weeks 21-24 to provide insights for assisting with long-term continuous abstinence. Results The CARs of all participants for weeks 9-12 and weeks 21-24 were 48.6% (95% CI 41.2-56.0) and 47.5% (95% CI 40.0-54.8), respectively. Program adherence rates were relatively high throughout (72% at week 12 and 60% at week 24). In the analysis of the factors related to the CAR at weeks 21-24, the number of entries in the app’s digital diary and number of educational videos watched during the first 12 weeks were significant factors. Conclusions The ascure program achieved favorable CARs, and participants showed high adherence. Proactive usage of the smartphone app may help contribute to smoking cessation success in the long-term.

Serological and virological examination of the presence of human and animal infection caused by West Nile Virus (WNV) as well as the presence of the virus in vectors, which has been conducted during the past few years, confi rmed an active virus circulation in the territory of the Republic of Serbia. Based on the obtained results and anticipated intense circulation of WNV, which poses substantial risks for both public and animal health in Serbia, and having in mind its crucial role in the protection of public health, Veterinary Directorate of the Ministry of Agriculture and Environmental Protection infront the Veterinary Service launched and funded the national WNV monitoring program starting from April 2014. The Program encompassed the entire territory of the Republic of Serbia and was conducted by scientific and specialized veterinary institutes and fi eld veterinary service in close collaboration with qualifi ed entomologists and ornithologists. The principal objective of the monitoring – surveillance program is early detection of WNV in monitored regions, timely reporting of the virus presence and activation of human health service institutions and local authorities aimed at establishing the control measures - eradication of mosquitoes, informing the local community and taking all relevant preventive measures for human health protection. Th e surveillance program of the WNV occurrence and spread is based on direct and indirect surveillance of WNV in natural environment. Indirect surveillance encompasses serological testing of seronegative sentinel horses and poultry for the presence of WNV infection, and it is performing continuously and periodically during the most intensive mosquito activity (May – September). The number of sentinel animals that should be tested was defi ned at the district level, according to the rate of anticipated risk of WNV infection. Direct surveillance was performed through periodical and continuous testing of pooled mosquitoes samples collected at two-week intervals during peak mosquito season (May – September) and samples of wild birds (tissues of dead birds and throat swabs of captured live susceptible bird species). The number of samples was stipulated according to the anticipated risk rate in particular regions.

In the article the problem of digital competence formation in the process of fire training is considered. In order to improve the training process for police officers, a new computer program has been developed that can be used with different categories of students in various forms of training: full-time, distance, and interactive. The Situation program proposed by the authors allows using distance learning tools in order to implement continuous training and maintain the level of readiness of ATS employees for effective operational and service activities. The program is used by students of educational organizations at the initial stage of training, in order to improve the skills of using firearms in various legally significant situations. Classes are conducted in the following modes: remotely or face-to-face. As a result, the motivation to achieve success increases, confidence increases; social responsibility, in particular, compliance with the law when making a decision about the use of firearms. The program consists of three modules: "Preparation", "photo Testing", and "Video testing". The student was offered theoretical materials necessary for making a decision about the use of firearms, testing on photos in a static image of a potential threat; testing on video fragments represents a complex of situations in which weapons are used.

VicRoads, the road authority for the state of Victoria, Australia, has been undertaking extensive research into the load capacity and performance of cast-in-place reinforced concrete flat slab bridges. One of the key objectives of this research is the development of analytical tools that can be used to better determine the performance of these bridges under loadings to the elastic limit and subsequently to failure. The 59-year-old Barr Creek Bridge, a flat slab bridge of four short continuous spans over column piers, was made available to VicRoads in aid of this research. The static testing program executed on this bridge was therefore aimed at providing a comprehensive set of measurements of its response to serviceability level loadings and beyond. This test program was preceded by the performance of a dynamic test (a simplified experimental modal analysis using vehicular excitation) to establish basic structural properties of the bridge (effective flexural rigidity, EI) and the influence of the abutment supports from identification of its dynamic modal characteristics. The dynamic test results enabled a reliably tuned finite element model of the bridge in its in-service condition to be produced for use in conjunction with the static testing program. The results of the static testing program compared well with finite element modeling predictions in both the elastic range (serviceability loadings) and the nonlinear range (load levels taken to incipient collapse). Observed collapse failure modes and corresponding collapse load levels were also found to be predicted well using yield line theory.

The newer methods of assessment that could become part of a licensure or certification program for physicians in the next decade include standardized patients which assess clinical skills and four computer-based methods that provide an assessment of cognitive ability: simple computerized tests, computer simulations, adapting item presentation, and continuous testing. The prognosis for standardized patients is mixed, with implementation more likely to occur outside of the U.S. Over the next five years, simple computerized tests will be implemented and significant strides will be made in computer simulations and adapting item presentations. These two methods should be implemented toward the end of the decade. The prognosis for the use of continuous testing is poor because so much fundamental work is needed.

Abstract Participation in a proficiency testing (PT) program is a valuable adjunct to laboratory activities dedicated to the maintenance of reliable analytical methods. The PT program may facilitate continuous quality improvement if laboratory performance is presented in the context of expectations espoused by healthcare professionals for optimal patient care. Statistical process control (SPC) and capability analysis are tools used by industry in a Total Quality Management environment to characterize and monitor the performance of its processes relative to performance specifications. I conceptualized the use of an analytical system by many laboratories as a process that periodically produces results from the analysis of PT specimens. I treated a set of five PT results (theophylline) reported by a laboratory as a process sample and subjected the samples collected from many laboratories to SPC and capability analysis. The control charts--mean-(X-bar) and s-charts--produced by the analysis readily identify significant analytical errors in the context of peer performance and performance specifications provided by the regulatory program and analytical goal setting. The capability index (desirable Cp > 1.0) determined from clinical specification limits for the three analytical systems evaluated suggests an opportunity for improvement of laboratory performance.

Full textAbstract:
Computerized adaptive testing (CAT) technology is widely used in a variety of licensing and certification examinations administered to health professionals in the United States. Many more countries worldwide are expected to adopt CAT for their national licensing examinations for health professionals due to its reduced test time and more accurate estimation of a test-taker’s performance ability. Continuous improvements to CAT algorithms promote the stability and reliability of the results of such examinations. For this reason, conducting simulation studies is a critically important component of evaluating the design of CAT programs and their implementation. This report introduces the principles of SimulCAT, a software program developed for conducting CAT simulation studies. The key evaluation criteria for CAT simulation studies are explained and some guidelines are offered for practitioners and test developers. A step-by-step tutorial example of a SimulCAT run is also presented. The SimulCAT program supports most of the methods used for the 3 key components of item selection in CAT: the item selection criterion, item exposure control, and content balancing. Methods for determining the test length (fixed or variable) and score estimation algorithms are also covered. The simulation studies presented include output files for the response string, item use, standard error of estimation, Newton-Raphson iteration information, theta estimation, the full response matrix, and the true standard error of estimation. In CAT simulations, one condition cannot be generalized to another; therefore, it is recommended that practitioners perform CAT simulation studies in each stage of CAT development.

Full textAbstract:
Background We aimed to determine the impact of a chlamydia (Chlamydia trachomatis) education program on the knowledge of and attitudes towards chlamydia testing of practice nurses (PNs). Methods: A cross-sectional survey was conducted at baseline and 6–12 months following recruitment with PNs in the Australian Chlamydia Control Effectiveness Pilot. Likert scales were analysed as continuous variables (scores), and t-tests were used to assess changes in mean scores between survey rounds and groups. Results: Of the 72 PNs who completed both surveys, 42 received education. Epidemiology knowledge scores increased significantly between surveys in the education group (P < 0.01), with change in knowledge being greater in the education group compared with the non-education group (P < 0.01). Knowledge of recommended testing scenarios (P = 0.01) and retesting following treatment (P < 0.01) increased in the education group. Attitudes to testing scores improved over time in the education group (P = 0.03), with PNs more likely to want increased involvement in chlamydia testing (P < 0.01). Change in overall attitude scores towards testing between surveys was higher in the education group (P = 0.05). Barriers to chlamydia testing scores also increased in the education group (P = 0.03), with change in barriers greater in the education vs the non-education group (P = 0.03). Conclusion: The education program led to improved knowledge and attitudes to chlamydia, and could be made available to PNs working in general practice. Future analyses will determine if the education program plus other initiatives can increase testing rates.

A program is being performed under the sponsorship of the United States Department of Energy, Office of Industrial Technologies, to improve the performance of stationary gas turbines in cogeneration through the selective replacement of metallic hot section components with ceramic parts. The program focuses on design, fabrication, and testing of ceramic components, generating a materials properties data base, and applying life prediction and nondestructive evaluation (NDE). The development program is being performed by a team led by Solar Turbines Incorporated, and which includes suppliers of ceramic components, U.S. research laboratories, and an industrial cogeneration end user. The Solar Centaur 50S engine was selected for the development program. The program goals included an increase in the turbine rotor inlet temperature (TRIT) from 1010°C (1850°F) to 1121°C (2050°F), accompanied by increases in thermal efficiency and output power. The performance improvements are attributable to the increase in TRIT and the reduction in cooling air requirements for the ceramic parts. The ceramic liners are also expected to lower the emissions of NOx and CO. Under the program uncooled ceramic blades and nozzles have been inserted for currently cooled metal components in the first stage of the gas producer turbine. The louvre-cooled metal combustor liners have been replaced with uncooled continuous-fiber reinforced ceramic composite (CFCC) liners. Modifications have been made to the engine hot section to accommodate the ceramic parts. To date, all first generation designs have been completed. Ceramic components have been fabricated, and are being tested in rigs and in the Centaur 50S engine. Field testing at an industrial co-generation site was started in May, 1997. This paper will provide an update of the development work and details of engine testing of ceramic components under the program.

Full textAbstract:
The performance of continuously reinforced concrete pavement (CRCP) in Texas has been quite satisfactory, primarily thanks to the continuous improvements in design and construction. However, severe spalling has been a major problem, and the Texas Department of Transportation (TxDOT) has sponsored several research projects since 1985 to identify solutions for this serious problem. Even though the research efforts were successful in identifying spalling mechanisms, developing a policy that TxDOT could easily implement has been a challenge. To develop a more practical solution to this problem, TxDOT initiated a research study, and the research efforts consisting of identifying CRCP projects with severe and no spalling, obtaining and conducting materials testing on concrete cores from those projects, analyzing the testing data, and performing theoretical analyses to validate the testing results. Among the material properties evaluated, the coefficient of thermal expansion (CTE) of concrete proved to have the best correlation with spalling. Detailed analyses of mechanistic behavior of concrete conducted with an object-oriented finite element program (OOF2) and commercial finite element program verified the reasonableness of the field-testing results. All concrete cores from CRCP with severe spalling had a CTE larger than 5.5 microstrains/°F, whereas no spalling was observed in concrete with a CTE less than that value. Based on this finding, TxDOT now requires the use of coarse aggregate that will produce concrete with a CTE of less than 5.5 microstrains/°F for CRCP construction. It is expected that this implementation will reduce the spalling in CRCP substantially.

This is a case study testing the hypothesis that the best value PIPS process is a sustainable process/structure. The best value PIPS process has been tested 450 times over 13 years. However, the process/structure has not been sustainable, meaning that users have been successful at individual tests, but unable to imbed the system into their organization and standard operating procedures. It has been resisted because it minimizes the need for construction management, simplifies the delivery process and transfers both risk and control to the contractors. The University of Minnesota approached the Performance Based Studies Research Group (PBSRG) to test and implement the process. Unlike other research clients, they agreed to meet the requirements for sustainability: implementing a long term strategic plan, using and instructing a core team, running tests before full implementation, and implementing continuous education to both client professionals and contractors. This study shows the results of the hypothesis testing.

This paper presents the results of an impact testing program that was conducted to characterize the energy absorption and failure characteristics of selected composite material systems and to compare the results with aluminum and steel. Composite tube specimens were constructed using graphite/epoxy (Gr/Ep), Kevlar/epoxy (K/Ep), and glass/epoxy (Gl/Ep) prepreg tape and were autoclave cured. Vertical impact and static compression tests were performed on 56 tubes. Tests results for energy absorption varied significantly as a function of lay-up angle and material type. In general, the Gr/Ep tubes had specific energy absorption values that were greater than those for K/Ep and Gl/Ep tubes having the same ply construction. Angle-ply Gr/Ep and K/Ep tubes had specific energy absorption values that were greater than those for 1024 steel tubes. Gr/Ep and Gl/Ep angle-ply tubes exhibited brittle failure modes consisting of fiber splitting and ply delamination, whereas the K/Ep angle-ply tubes collapsed in an accordian buckling mode similar to that obtained for metal tubes.

AbstractInappropriate use of antibiotics is contributing to a serious antimicrobial resistance problem in Asian hospitals. Despite resource constraints in the region, all Asian hospitals should implement antimicrobial stewardship (AMS) programs to optimize antibiotic treatment, improve patient outcomes, and minimize antimicrobial resistance. This document describes a consensus statement from a panel of regional experts to help multidisciplinary AMS teams design programs that suit the needs and resources of their hospitals. In general, AMS teams must decide on appropriate interventions (eg, prospective audit and/or formulary restriction) for their hospital, focusing on the most misused antibiotics and problematic multidrug-resistant organisms. This focus is likely to include carbapenem use with the goal to reduce carbapenem-resistant gram-negative bacteria. Rather than initially trying to introduce a comprehensive, hospital-wide AMS program, it would be practical to begin by pilot testing a simple program based on 1 achievable core intervention for the hospital. AMS team members must work together to determine the most suitable AMS interventions to implement in their hospitals and how best to put them into practice. Continuous monitoring and feedback of outcomes to the AMS teams, hospital administration, and prescribers will enhance sustainability of the AMS programs.

This narrative review describes implementation, current status and perspectives of a pharmacogenomic (PGx) program at the Brazilian National Cancer Institute (INCA), targeting the cancer chemotherapeutic drugs – fluoropyrimidines, irinotecan and thiopurines. This initiative, designed as a research project, was supported by a grant from the Brazilian Ministry of Health. A dedicated task force developed standard operational procedures from recruitment of patients to creating PGx reports with dosing recommendations, which were successfully applied to test 100 gastrointestinal cancer INCA outpatients and 162 acute lymphoblastic leukemia pediatric patients from INCA and seven other hospitals. The program has been subsequently expanded to include gastrointestinal cancer patients from three additional cancer treatment centers. We anticipate implementation of routine pre-emptive PGx testing at INCA but acknowledge challenges associated with this transition, such as continuous financing support, availability of trained personnel, adoption of the PGx-informed prescription by the clinical staff and, ultimately, evidence of cost–effectiveness.

Lean Six Sigma (LSS) is an effective methodology that aims to maximize shareholder value by improving quality, efficiency, customer satisfaction and costs. Continuous integration is the software engineering practice of rapid and automated development and testing. A case study presented in this paper demonstrates how LSS tools help software R&D teams to improve product quality and reduce development cost. The define, measure, analyze, improve and control (DMAIC) methodology is applied to develop an action plan to achieve continuous integration at an anonymous software R&D organization's LSS Green Belt project. The LSS implementation has had a significant impact on the financial performance of the organization. It is showed that the package continuous integration (PCI) success ratio (3 months average) increased from 27% to 74%, meanwhile an operational saving of approximately 56.87K Euro was reported from this project. Finally, some key success factors that are critical to the implementation of an effective Green Belt program are examined, and managerial implications are provided.

Abstract The Fast Fourier Transform (FFT) has been used increasingly in such tire tests as uniformity, ride vibration analysis, acoustic intensity measurement, and modal analysis of tire and vehicle structures. A new application for the FFT is in monitoring tire endurance and high speed tests to identify significant changes in tire structural integrity and to provide advanced warning of impending tire failure so that the test may be terminated prior to ultimate failure of the tire. Greater information concerning the initiation of failure can then be obtained than is possible by trying to reconstruct the remains of a failed tire. Continuous display of FFT analysis of tire carriage vibrations reveals one to fifteen harmonics of tire rotation frequency on a new tire, with higher harmonics growing with test time. Just prior to failure, these higher harmonics grow in unison to very high levels with a “white-harmonic” spectrum appearing. Since the tire would then fail within 5 to 20 seconds, the test should be terminated. This paper details the techniques applied and the results obtained to date in creating a test monitoring program that will notify the test operator of significant test developments, and in automatic shutdown of tires nearing failure.

Exercise electrocardiogram (ECG) testing in conjunction with radionuclide imaging provides prognostic, diagnostic, and important physiological information regarding the presence of ischemia. However, many patients cannot or will not exercise to 85% of maximal heart rate. When this occurs, potential disparities in regional myocardial perfusion may not be apparent. Pharmacological stress testing with intravenous (IV) dipyridamole provides an alternative method of increasing intracoronary blood flow in these patients and decreasing the incidence of suboptimal exercise myocardial perfusion scans. An ongoing program was begun in 1992 to determine the effect of using pharmacological stress testing with IV dipyridamole (in selected patients) on the incidence of suboptimal exercise myocardial perfusion scans. Myocardial perfusion scans from the months of February 1991 and February 1992 were reviewed. Data collected included demographic variables, heart rate, percent of maximum predicted heart rate, anti-anginal drug therapy, and any underlying conditions that could influence the patient's ability to exercise adequately. There was only a slight reduction in inadequate exercise tests between the two study periods, 30% in February 1991 and 23% in February 1992, without pharmacist intervention. There was an increase in the number of dipyridamole perfusion scans, one (<1%) in February 1991 and 10 (6%) in February 1992. These data were presented to physicians as part of an educational program on the availability and appropriate use of pharmacological stress testing with IV dipyridamole. Several suggestions were made to assist in decreasing the incidence of suboptimal exercise myocardial perfusion scans. The review was repeated in February 1993. There was a further increase in the number of dipyridamole perfusion scans (18, or 11% over previous levels); however, the rate of suboptimal exercise tests remained at 24%. This review offered an easy and unique opportunity for the pharmacy to be involved in multidisciplinary continuous quality improvement with nuclear medicine and cardiology. It is anticipated that with continued education and a change in patient screening procedures, along with the development and use of drug use guidelines, a decrease in the number of suboptimal exercise myocardial perfusion scans may be realized.

A bridge deck panel system using nonprestressed full-depth precast concrete bridge deck panels with continuous shear pockets was investigated. First, the research team performed conceptual improvement, design, detailing, and fabrication studies on a specific deck replacement system (System CD-2) previously proposed by NCHRP Project 12-65 researchers. Key improvements to the CD-2 deck panel system included modifications to the transverse joint coupler for ease of construction and the addition of a longitudinal staged-construction joint to expedite bridge deck replacement projects. Next, an experimental program was carried out to construct and perform service-level load testing on a full-size precast deck panel assemblage that incorporated the refinements. On the basis of static and cyclic loading test results, it was found that the modified CD-2 deck panel system as a whole performed satisfactorily with regard to AASHTO serviceability requirements.

They require compliance with certain web standards and support for multiple different browsers and devices. To be convinced of the version of the published code, we need a team that loves challenges, has the creativity and a desire for constant learning. Code, as a basis for a successful business, must be written appropriately with minimal deficiencies in logic and writing. The correctness and validity of the production code mostly depend on the program team itself and its responsibility for the written code. Vital code with errors can produce serious problems and unforeseen consequences. To achieve complete accuracy of all parts of the written code, it is necessary to use software testing and QA technique - quality assurance. The focus of the work is on the application and writing of the necessary programming code that uses QA/QC and the black-box method of testing the existing webshop. After analysis, the authors conclude that software quality control will be a constant challenge for many companies to survive in the short term of the adjustment process and that the crisis is an opportunity for courageous companies to invest ambitiously and timely in their internet business to become market leaders.

New electrical machines design assumes the execution of research and test-design works with a choice and selection of the effective technical solutions. The prototypes characteristics control is implemented by testing them in laboratory using the automated tools and methods. The automation provides relevant datasets for further analysis. In the paper the algorithms and methods for studying the general purpose induction motors performance characteristics have been proposed. The changes of dependence of the motor efficiency on the output power alterations, caused by using different technical solutions, have been studied. Based on experience of the electrical machines testing in a specialized laboratory, the task of evaluating the induction motors energy efficiency when operating in S1 mode (continuous duty) with overloads occurrence, has been formulated. A method for solving the problem based on the efficiency curves has been proposed. The results have been implemented in a computer program and can be used to improve the technical solutions, allowing an achievement of the target energy efficiency indicators.

Full textAbstract:
The evaluation of groundwater quality has become increasingly important as more industrial waste and solid domestic refuse come into contact with groundwater. One method of detecting contaminated groundwater is by noting the electrical resistivity of the contaminated soil. This method has been applied at the University of British Columbia by the development and use of a new resistivity cone. The resistivity cone consists of four circumferential surface electrodes contained in a separate module behind a 15 cm2 piezocone. The cone has a capability of providing a continuous record of resistivity with depth.Initially, a laboratory testing program was carried out using a simplified probe design to ensure the feasibility of the project. On the basis of favourable laboratory results the module was constructed, calibrated in the laboratory, and then field tested. The paper describes the design and operation of the resistivity cone, theory and laboratory calibration, and test results from three sites in the lower mainland of British Columbia. The results of the testing program provided evidence of the reliability of the instrument and illustrated its application in determining changes in groundwater quality. Factors affecting results and applications of the resistivity cone in contaminant site investigations are discussed. Key words: electrical, resistivity, cone, groundwater, contamination, plumes, mapping, in-situ testing, soil.

Full textAbstract:
The relationship between molding water content and hydraulic conductivity of a compacted sand-bentonite mixture was examined in a laboratory test program. This program involved triaxial permeability testing of nine specimens of 8% bentonite and Ottawa sand, compacted at standard Proctor density using molding water contents ranging from6 to 19%. The permeability tests were conducted using hydraulic gradients ranging from 19 to 40. The specimens were subjected to an average effective stress during testing of 21 kPa. The tests were conducted using continuous back pressure saturation. Each test was run for a minimum of 40 000 min (approximately 28 days) to enable the flow in and out of the specimen to come to equilibrium with respect to each other. The hydraulic conductivity decreased from 6.5 × 10−9 cm/s for a molding water content of 5.9% to 1.4 × 10−9 cm/s for a molding water content of 15.8%. However, although the hydraulic conductivity was related to the molding water content, the variation in hydraulic conductivity was relatively small. Therefore, the low values reported for all hydraulic conductivity tests suggest that molding water content is not a critical design factor in the construction of a low-permeability sand-bentonite liner.

Full textAbstract:
Accredited degree programs primarily use graded assignments in the embedded-course method to measure individual-level assurances of learning (AoL). This method is expensive, subjective, retrospective, and difficult to implement for continuous program improvement. The purpose of our research is to explore the use of entrepreneurial self-efficacy (ESE) as an individual-level AoL outcome to augment the quality management of accredited entrepreneurship degree programs. Previous research on ESE, arising from intention models and theory of planned behavior, has used the construct primarily for predicting start-up intent or differentiating nonentrepreneurs from entrepreneurs. In contrast, we begin from an educational assessment and social cognitive theory perspective in constructing our ESE scale. The new ESE scale is operationalized by theoretically justifying 8 learning outcomes, testing 70 items based on scales in the extant literature, and extracting 11 factors or subdomains of ESE using principal components analysis to create a parsimonious new 44-item ESE scale. Expanding the ESE construct to 11 subdomains also expands the use of ESE into the fields of educational assessment, AoL, and program accreditation. This enables understanding the links between pedagogy, curriculum, assignments, grades, enactive mastery experiences, and peer feedback to achieve meaningful student transformation through self-efficacy beliefs.

Full textAbstract:
This paper presents the results of an experimental program of model piles in carbonate soil from the Red Sea. Direct and triaxial shear tests of the soil indicated very high effective angles of friction. These angles were greatly affected by confining pressures and relative densities. Results of model pile tests with and without applied surcharge pressures showed early peak frictional resistances for different relative densities. The peaks were stronger in the former case and followed by strain softening down to "stable" residual values. These residual values were found to be comparable with limiting values of friction predicted on the basis of limiting compressibility indices. Also, it was noticed that at the beginning of penetration, most of the applied load was taken by end bearing, but frictional share increased with further penetration until it took more than 50% of the load. Calculated values of the lateral soil pressure coefficient, Ks, showed a continuous decrease with penetration and it stabilized at deeper depths. Statistical correlations were found to relate Ks with the L/D ratio and surcharge pressure. Key words: ocean soil, sand, shear strength, pile, model test, bearing capacity, friction, uplift, active and passive earth pressures.

Full textAbstract:
Background Aerobic activity positively affects patients recovering from stroke and is part of best practice guidelines, yet this evidence has not been translated to routine practice. Objective The objective of this study was to evaluate the feasibility of a model of care that integrated aerobic training in an inpatient rehabilitation setting for patients in the subacute stage of stroke recovery. Key elements of the program were personalized training prescription based on submaximal test results and supervision within a group setting. Design This was a prospective cohort study. Methods Participants (N=78) completed submaximal exercise testing prior to enrollment, and the test results were used by their treating physical therapists for exercise prescription. Feasibility was evaluated using enrollment, class attendance, adherence to prescription, and participant perceptions. Results Overall, 31 patients (40%) were referred to and completed the exercise program. Cardiac comorbidities were the main reason for nonreferral to the fitness group. Program attendance was 77%; scheduling conflicts were the primary barrier to participation. The majority of participants (63%) achieved 20 minutes of continuous exercise by the end of the program. No adverse events were reported, all participants felt they benefited from the program, and 80% of the participants expressed interest in continuing to exercise regularly after discharge. Limitations Cardiac comorbidities prevented enrollment in the program for 27% of the admitted patients, and strategies for inclusion in exercise programs in this population should be explored. Conclusions This individualized exercise program within a group delivery model was feasible; however, ensuring adequate aerobic targets were met was a challenge, and future work should focus on how best to include individuals with cardiac comorbidities.

Full textAbstract:
In the health and social sectors, many diagnostic and prognostic tests are carried out without a constant watch on (1) what influence the test results have on decisions, and (2) the impact of these decisions on every day clinical work. Consequently, it is not known whether the additional information gained, if any, justifies the expenditure necessary for resources involved in a testing procedure. In fact, the net impact of testing in every day clinical work may be negative. By carrying out a testing procedure, under the before mentioned conditions, resources would be wasted. Since the early 1970's a battery of standardized performance tests have been used at the Vocational Rehabilitation Clinic in Aarhus, Denmark. Originally, the aim of the tests was to identify and give an early discharge to those clients, that were, in any case, shown to be fit for a social pre-term pension. An early discharge of these clients would enable the Clinic to counsel a greater number of clients who were suited to vocational rehabilitation. The test period lasts two weeks, and the average stay in the Clinic amounts to about 3 months. During the years 1981 to 1983, a total of 607 clients were discharged from the Clinic. Out of the 607, 379 had been given the battery of tests. Those tested stayed 16 days longer at the clinic than the rest of the clients. A few clients got an early discharge. The associations between the test results and case closure status were weak. Furthermore, these weak associations occurred in 6 out of 51 tests. On the other hand, case closure status could be predicted on the basis of already available demographic, social, and health information on the individual clients. The conclusion is, that standardized performance testing seems to have raised the resource consumption of the clinic without any demonstrable benefit in terms of client selection. The need for continuous socio-medical and epidemiological evaluation of rehabilitation tests and procedures is stressed.

The purpose of this research was to investigate full-day kindergarten, as a means of improving later academic achievement. A total of 208 students who had continuous enrollment for three consecutive school years from a school district in southern California participated in the study. The sample contained 165 students who had attended the traditional half-day kindergarten program with 43 attending a hybrid all-day kindergarten program. All students were administered the California Standardized Testing and Reporting (STAR) assessment and the California Achievement Test 6th Edition (CAT 6) survey exams. Using stepwise multiple regression, several independent variables were introduced into the regression equation to obtain a Prediction Model of Student Success. The English language arts and math scores of the California STAR Assessment were used as the dependent variable separately. A significant model was not developed. Using an independent-sample T Test procedure, comparing the two groups, was also preformed revealing that there were no significant differences in students who attended the all-day kindergarten program and students who attended a traditional kindergarten program.

Full textAbstract:
Wire ropes as internal shear reinforcements could are an economic alternative to conventional stirrups in rectangular concrete beams, mainly due to their attractive advantages such as high flexibility, light weight, and strength. The aim of this study is to enhance the understanding of the shear behavior of concrete beams with continuous spiral-type wire rope as internal shear reinforcement. In order to achieve this objective, an experimental program involving the testing of six beam specimens under four-point load was conducted. Digital image correlation technique was employed to study the crack formation and propagation in the beam specimens. The test results demonstrated that using continuous spiral-type wire rope as shear reinforcement is highly favorable for diagonal crack control. In particular, spiral-type wire rope specimens attained serviceability crack width at a higher load than that of normal stirrup beam specimens.
