  1. Methods and Conditions for Achieving Continuous Improvement of Processes

    Florica BADEA; Catalina RADU; Ana-Maria GRIGORE

    2010-01-01

    In the early twentieth century, the Taylor model improved, in a spectacular maner the efficiency of the production processes. This allowed obtaining high productivity by low-skilled workers, but used in large number in the execution of production. Currently this model is questioned by experts and was replaced by the concept of "continuous improvement". The first signs of change date from the '80s, with the apparition of quality circles and groups of operators on quality issues, principles whi...

  2. Role of continual environmental performance improvement in achieving sustainability in uranium production

    Although the term sustainable development is commonly used today, there is not yet a commonly accepted definition. Various ways of measuring sustainability have been proposed. To show how these issues are being effectively addressed in modern uranium developments, we will review some methods of defining the environmental component of sustainable development in the mining and mineral-processing sector. Environmental impacts associated with uranium extraction and processing in modern facilities are modest. Air and water emissions are well controlled. Waste materials are subject to comprehensive management programmes. The size of the impacted area is smaller than in other energy sectors, providing good opportunity to minimize land impact. Experience over the past three decades facilitated gradual, persistent, but cumulatively significant environmental improvements in the uranium production sector. Cameco's uranium mining and processing facilities exemplify these improvements. These improvements can be expected to continue, supporting our argument of Cameco's environmental sustainability.

    Problem Current models of health care quality improvement do not explicitly describe the role of health professions education. The authors propose the Exemplary Care and Learning Site (ECLS) model as an approach to achieving continual improvement in care and learning in the clinical setting. Approach From 2008–2012, an iterative, interactive process was used to develop the ECLS model and its core elements—patients and families informing process changes; trainees engaging both in care and the improvement of care; leaders knowing, valuing, and practicing improvement; data transforming into useful information; and health professionals competently engaging both in care improvement and teaching about care improvement. In 2012–2013, a three-part feasibility test of the model, including a site self-assessment, an independent review of each site’s ratings, and implementation case stories, was conducted at six clinical teaching sites (in the United States and Sweden). Outcomes Site leaders reported the ECLS model provided a systematic approach toward improving patient (and population) outcomes, system performance, and professional development. Most sites found it challenging to incorporate the patients and families element. The trainee element was strong at four sites. The leadership and data elements were self-assessed as the most fully developed. The health professionals element exhibited the greatest variability across sites. Next Steps The next test of the model should be prospective, linked to clinical and educa tional outcomes, to evaluate whether it helps care delivery teams, educators, and patients and families take action to achieve better patient (and population) outcomes, system performance, and professional development.

  8. Baseline budgeting for continuous improvement.

    Kilty, G L

    1999-05-01

    This article is designed to introduce the techniques used to convert traditionally maintained department budgets to baseline budgets. This entails identifying key activities, evaluating for value-added, and implementing continuous improvement opportunities. Baseline Budgeting for Continuous Improvement was created as a result of a newly named company president's request to implement zero-based budgeting. The president was frustrated with the mind-set of the organization, namely, "Next year's budget should be 10 to 15 percent more than this year's spending." Zero-based budgeting was not the answer, but combining the principles of activity-based costing and the Just-in-Time philosophy of eliminating waste and continuous improvement did provide a solution to the problem.

  9. Improved continuity of reduced graphene oxide on polyester fabric by use of polypyrrole to achieve a highly electro-conductive and flexible substrate

    Berendjchi, Amirhosein; Khajavi, Ramin; Yousefi, Ali Akbar; Yazdanshenas, Mohammad Esmail

    2016-02-01

    A flexible and highly conductive fabric can be applied for wearable electronics and as a pliable counter electrode for photovoltaics. Methods such as surface coating of fabrics with conductive polymers and materials have been developed, but the roughness of fabric is a challenge because it creates discontinuity in the coated layer. The present study first coated polyethylene terephthalate (PET) fabric with reduced graphene oxide sheets; RGO and then filled the gaps with polypyrrole (PPy). The samples were first dipped in graphene oxide (GO) and then reduced to RGO. They were next coated with PPy by in situ polymerization. The results showed that the presence of oxidative agent during synthesis of PPy oxidized the RGO to some extent on the previously RGO-coated samples. PPy was more uniform on samples pre-coated with RGO in comparison those coated with raw PET. The RGO-PPy coated samples exhibited 53% and 263% lower surface resistivity values than samples coated only with PPy and RGO, respectively. There was no significant difference between the tenacity of samples but the bending rigidity of samples increased. The RGO-PPy coated fabric displayed properties, such as excellent UV blocking (UPF = 73), antibacterial activity, improved electrochemical behavior and thermal stability which make it a multifunctional fabric.

  10. Continuous improvement of pump seals

    Pump seal reliability continues to be an area needing improvement and ongoing vigilance. Methods have been developed for identifying and assessing factors relating to seal performance, selecting the most relevant ones for a specific station, and then focusing on the most significant aspects and how to improve. Discussion invariably addresses maintenance practices, seal design, monitoring capabilities, operating conditions, transients, and pump and motor design. Success in reliability improvement requires ongoing dialogue among the station operators, pump manufacturers and seal designers. AECL CAN-seals lead the nuclear industry in reliability and seal life. They effectively save operators millions of dollars in outage time and person-rem. This paper describes some of the significant developments in AECL's ongoing program in seal R and D, as well as recent new installations following the most demanding seal qualification programs to date.

  11. Sustaining motivation for continuous improvement

    Jørgensen, Frances; Kofoed, Lise Busk

    2007-01-01

    The objective of this article is to explore possibilities for improving motivation for participation in Continuous Improvement (CI). Due to a number of issues, for example, challenges with measuring outcomes of CI activities on performance, the inherent slower, incremental rather than big bang...... nature of CI, and the perception of CI as being something done in addition to normal job responsibilities, motivation for participation may dwindle over time. Because CI is dependent on active participation of all members of the organization, including shop floor workers, sustaining motivation for CI...... activities is an important issue for managers. The paper begins with a short description of CI, with an emphasis on barriers to successful implementation cited in the literature. Thereafter, a number of widely-acknowledged-albeit perhaps somewhat dated-theories of motivation are explored in relation to the...

  12. Quick and continuous improvement through kaizen blitz.

    McNichols, T; Hassinger, R; Bapst, G W

    1999-05-01

    It is our objective to provide you with a step-by-step approach to conducting a kaizen blitz within two days and describe how to achieve dramatic performance improvement with employee buy-in through this process. Kaizen blitz has been used dozens of times by the authors, and in some instances the same area has been blitzed as many as four times, with significant improvements each and every time. Employees have even taken it on themselves to conduct informal blitzes as a continuing improvement effort after a formal blitz has been conducted in their area. Blitzes can succeed in a variety of environments. The morning after the employees of one company attended this presentation, they self initiated a mini-blitz and discovered opportunities for improvement that they enthusiastically presented to management.

  13. KEY FACTORS FOR A CONTINUOUS IMPROVEMENT PROCESS

    Hector Ricardo Formento

    2013-11-01

    Full Text Available The goal of this work was to examine the content of continuous improvement strategies, taking into account the important role they play in building competitiveness. This paper argues that several specific issues must be taken into account in order to reach successful outcomes. This work starts with a literature review on the matter. On this basis, we designed a survey administered to a group of 30 large companies, each of which is renowned leader in Argentina. Finally, we compared the development of continuous improvement process in companies with very effective results and with scarce results. Differences that emerged from this comparison enabled us to identify critical factors for achieving a successful improvement process. As there are no recent researches on continuous improvement programs in Argentina, this paper contributes to recognizing and systematizing what has been done, comparing it with theoretical framework and uncovering research gaps for future studies. However, further research must confirm these findings and move forward on the analysis of intangible factors, like: internal communications, climate, culture, self reflexion, consensus, etc.

    1998-01-01

    As the new millennium approaches, a long anticipated reckoning for the education system of the United States is forthcoming, Years of school reform initiatives have not yielded the anticipated results. A particularly perplexing problem involves the lack of significant improvement of student achievement in math and science. Three "Partnership" projects represent collaborative efforts between Xavier University (XU) of Louisiana, Southern University of New Orleans (SUNO), Mississippi Valley State University (MVSU), and the National Aeronautics and Space Administration (NASA), Stennis Space Center (SSC), to enhance student achievement in math and science. These "Partnerships" are focused on students and teachers in federally designated rural and urban empowerment zones and enterprise communities. The major goals of the "Partnerships" include: (1) The identification and dissemination of key indices of success that account for high performance in math and science; (2) The education of pre-service and in-service secondary teachers in knowledge, skills, and competencies that enhance the instruction of high school math and science; (3) The development of faculty to enhance the quality of math and science courses in institutions of higher education; and (4) The incorporation of technology-based instruction in institutions of higher education. These goals will be achieved by the accomplishment of the following objectives: (1) Delineate significant ?best practices? that are responsible for enhancing student outcomes in math and science; (2) Recruit and retain pre-service teachers with undergraduate degrees in Biology, Math, Chemistry, or Physics in a graduate program, culminating with a Master of Arts in Curriculum and Instruction; (3) Provide faculty workshops and opportunities for travel to professional meetings for dissemination of NASA resources information; (4) Implement methodologies and assessment procedures utilizing performance-based applications of higher order

    2014-06-01

    Using the framework of ITIL best practises, the service managers within CERN-IT have engaged into a continuous improvement process, mainly focusing on service operation. This implies an explicit effort to understand and improve all service management aspects in order to increase efficiency and effectiveness. We will present the requirements, how they were addressed and share our experiences. We will describe how we measure, report and use the data to continually improve both the processes and the services being provided. The focus is not the tool or the process, but the results of the continuous improvement effort from a large team of IT experts providing services to thousands of users, supported by the tool and its local team. This is not an initiative to address user concerns in the way the services are managed but rather an on-going working habit of continually reviewing, analysing and improving the service management processes and the services themselves, having in mind the currently agreed service levels and whose results also improve the experience of the users about the current services.

  6. Continuous supply chain collaboration: Road to achieve operational excellence

    N. Senthil Kumar

    2011-04-01

    Full Text Available Supply chain management (SCM is becoming critical as firms recognize that competition is shifting from company versus company to supply chain versus supply chain. In the present competitive scenario, the fierce competition has driven most companies to seek for means of enhancing performance beyond their four wall boundaries. The firm’s ability in collaborating with its upstream and downstream partners determines its success in attaining better performance with supply chain collaboration; a firm is able to serve fragmented markets in which end customers require more product varieties and availability with shorter product life cycle and, at the same time, lower supply chain costs. This paper introduces the framework of continuous supply chain collaboration (CSCC, which extends the traditional frame of reference in strategic sourcing from a supplier centric to a supply-chain-scope as continuous improvement efforts to enhance the customer satisfaction. CSCC practices are rather exceptional, yet CSCC is believed to be the single most comprehensive framework for attaining operational excellence.

  7. CONTINUOUS IMPROVEMENT THROUGH INTEGRATION OF QUALITY TOOLS

    2006-01-01

    The relationship between major quality tools such as quality function development (QFD),failure mode and effects analysis (FMEA), design of experiments (DOE) and statistical process control (SPC) is analyzed through an extensive review of the literature and the concurrent quality engineering philosophy, and a basic structure for the integration of quality tools is presented. An integrated quality management system (IQMS) is developed using C++ Builder, nmning in the Windows 2000 Server environment with the basic internet connections, and SQL Server 2000 as the platform for developing the database. An illustrative example applying IQMS to the continuous quality improvement for a crane equipment manufacturing is reported. The result shows that the application of IQMS can optimize the process of design and manufacturing, shorten the cycle time of product, reduce the cost, and realize quality improvement continuously. The proposed integrated framework with IQMS is believed to be applicable to continuous quality improvement in many manufacturing companies.

  9. INSIDE CONTINUOUS IMPROVEMENT - A LITERATURE REVIEW

    Daniel Indarto Prajogo

    2000-01-01

    Full Text Available This paper discusses the concept of continuous improvement (CI by looking beyond what traditionally highlighted in literature concerning continuous improvement or Total Quality Management (TQM. The primary argument put forwarded in the discussion is that despite the undeniable positive results from CI practices, the way these activities are implemented, however, will lead to most programs becoming self-limiting. It needs to be asserted here that this paper is not intended to despise CI, rather, its purpose is limited only to provide a balance on the prevailing positive views toward CI.

  16. Continuous improvement: A win-win process

    The strategies used within PanCanadian Petroleum Limited's production division to successfully introduce the continuous improvement (CI) process are discussed. Continuous improvement is an operating philosophy and management style which allows all employees to participate in and improve the way an organization performs its day-to-day business. In the CI work environment the supervisor's traditional role changes from one of monitoring and controlling, to one of inspiring, motivating and leading people by communicating a clear vision. Employees at all levels in the work environment are organized into teams and armed with a good working knowledge of the problem-solving tools which allow them to pursue and implement improvement initiatives. The outcome of the process is an ongoing win-win situation for both PanCanadian and its people. Employees are gaining more trust, eliminating job irritants, and enjoying their work in a team environment. The company is benefiting through increased production, improved safety and reduced operating expenses, thanks to the many innovative ideas introduced by employees. 4 refs

  20. Achieving Improved Ohmic Confinement via impurity injection

    Improved Ohmic Confinement (IOC) was obtained in ASDEX after a modification of the divertors that allowed a larger (deuterium and impurity) backflow from the divertor chamber. The quality of IOC depended crucially on the wall conditions, i.e. IOC was best for uncovered stainless steel walls and vanished with boronization. Furthermore, IOC was found only in deuterium discharges. These circumstances led to the idea that IOC correlates with the content of light impurities in the plasma. To substantiate this working hypothesis, we present observations in deuterium discharges with boronized wall conditions into which various impurities have been injected with the aim to induce IOC conditions. The remainder of this contribution is organized according to the following lines: Firstly, the plasma behaviour in typical IOC discharges is characterized. Secondly, injection experiments with the low-Z impurities nitrogen and neon as well as with the high-Z impurities argon and krypton are discussed. Then, we concentrate on optimized neon puffing that yields the best confinement results which are similar to IOC conditions. Finally, these results are compared with experiments in other tokamaks and some conclusions are drawn about the effects of the impurity puffing on both, the central and the edge plasma behaviour.

  2. Continuous improvement: A win... win process

    Implementing a continuous improvement (CI) process within PanCanadian's oil and gas production operations might have been a simple assignment if one were not also trying to capture the hearts and imaginations of the people in a changing work environment. Meeting the challenge is resulting in big payoffs to both the organization and its people. The plan used within the Company's Production Division to successfully introduce the CI process is discussed. A brief insight is provided on the process philosophy, with emphasis placed on planning, training and coaching used to launch the process. Also reviewed at length are the impediments to change and the challenges faced when changing an organization's culture. In a CI work environment, the supervisor's traditional role changes from one of monitoring and controlling to one of inspiring, motivating and leading people by communicating a clear vision.

  3. Achieving optimal diabetic control in adolescence: the continuing enigma.

    McConnell, E M; Harper, R; Campbell, M; Nelson, J K

    2001-01-01

    The transition from childhood through adolescence to adulthood is a difficult stage, particularly for patients with type 1 diabetes. The yearning for autonomy and independence, as well as the hormonal changes around the time of puberty, can manifest in poor glycaemic control. The focus on diet and weight increases the prevalence of eating disorders, compounding the difficulties in supervising diabetes patients. This can be exacerbated by the realisation that hyperglycaemia induces weight loss and the use of this knowledge to further manipulate diabetes control to gain a desired body image. The management of adolescents with type 1 diabetes is therefore challenging and requires close collaboration between psychological medicine and diabetes teams. This review describes the difficulties frequently encountered, with a description of four cases illustrating these points. Case 1 demonstrates the problem of needle phobia in a newly diagnosed patient with type 1 diabetes leading to persistent hyperglycaemia, the recognition of weight loss associated with this and the development of bulimia. The patient's overall management was further complicated by risk-taking behaviour. By the age of 24 years, she has developed diabetic retinopathy and autonomic neuropathy and continues to partake in risk-taking behaviour. Case 2 illustrates how the lack of parental support shortly after the development of type 1 diabetes led to poor glycaemic control and how teenagers often omit insulin to accommodate lifestyle and risk-taking behaviour. Case 3 further exemplifies the difficulty in managing patients with needle phobia and the fear of hypoglycaemia. Case 4 adds further weight to the need for parental support and the impact of deleterious life events on glycaemic control by manipulation of insulin dosage. PMID:11241893

    Knowledge management is one of the newest strategies for organizations to improve their productivity. Oil companies seeking business sustainability are faced with the challenge of continuously improving their operations. This paper emphasized that in order to improve, companies must gain valuable experience through planning, perseverance, commitment and processes that accumulate results. It presented a visual methodology, based on symbolisms and key words, which is intended to facilitate the assimilation of the continuous improvement program structure from knowledge management. The concepts of Garvin, Nonaka and Takeuchi were presented as means for improving the capacity of an organization seeking a learning atmosphere through the prioritization of actions to facilitate team activities and accumulate knowledge in the individual. It was shown that Japanese companies in the production sector have used 4 processes of knowledge conversion: socialization, exteriorization, internalization and their combinations. The Garvin concept has proposed that continuous improvement of an organization would be more positive if the companies learnt a basic lesson. This paper articulated resulting observations from Garvin and from Nonaka and Takeuchi theories and proposed recommendations based on symbolism for identifying action strategies and achievement objectives. Issues regarding working conditions and the influence on learning were discussed along with different ways to transfer knowledge in terms of competencies and skills. 14 refs., 7 figs.

    Full Text Available Abstract In this paper using quality management tools we track root causes and principal causes of the rising manufacturing cost of the bar soaps and propose solution to solve the problem. First we identify and analyze the roots causes of problem with the Fishbone Diagram. We use multivoting approach to reduce roots causes to main causes from which we identify classify and analyze principal causes using the Pareto Diagram. We then perform a deep analysis of these principal causes using the 5 whys analysis technique. Three principal causes were found amp61480high level of overtime poor machine performance and poor employees performanceamp61481 and were weighing 55 of the problem. For that reason working on these areas was necessary to address the problem of the rising manufacturing cost of the bar soaps. With the result we then use the PDCA 7 steps of TQM method to solve the problem of the rising manufacturing cost by testing whether expanding production capacity leads to performance improvements of these areas. We decide to expand production capacity by adding two more machine groups. Six months after implementation of the proposed solution the result shows an enhanced workload and schedule an increased production capacity an elimination of the overtime issue an increased machines performance and an improved workers performance. Two main savings were achieved as wage costs and maintenance costs. As a result while competitors bar soaps prices increased the company bar soaps price decreased by 50 making the company bar soaps more attractive on market as this performance permitted the company to apply price reduction at the retailer level.

  6. Organisational learning: A tool for continuous improvement of the organization

    We are used to hear a success company in today's world is not possible unless a continuous improvement is developed. How can we be successful in the nuclear plant? We have to achieve safety for workers, people and environment in the first step, and for the second step availability and reliability for systems and components to avoid failure of components that could reduce availability. The aim is to search for new measures to reach this way. One of the improvements implemented in the plants to improve continuously was mainly Operating Experience activities, which was based in event analysis in the plants, causes identification, and to implement corrective actions. For External Operating Experience the aim was to learn from others to avoid occurrence of events in our plants. This was the lessons learned from Three Mile Island event. This was the learning process implemented so far, to get a continuous improvement. So far, the developed capabilities for process improvement follow the Operating Experience process that could be considered classical and will be revitalized nowadays. (Author)

    Saturno-Hernández, Pedro J; Hernández-Avila, Mauricio; Magaña-Valladares, Laura; Garcia-Saisó, Sebastián; Vertiz-Ramírez, José de Jesús

    2015-01-01

    While the Mexican health system has achieved significant progress, as reflected in the growing improvement in population health, heterogeneity in the quality of services and its impact on health in different population groups is still a challenge. The costs or poor quality represent about 20 to 40% of the health system's expenditure. We need to develop organizational capacity to implement quality management systems in order to identify, evaluate, prevent and eventually overcome the health system's challenges. A competency-based comprehensive strategy for training human resources is proposed including undergraduate and graduate education as well as continuing education, which will contribute to improve the quality function at the various levels of responsibility in the health system. The proposed strategy responds to the context of the Mexican health system, but it could be adapted to other systems and contexts. PMID:26302131

    Phillips, Jeffrey A; Clemmer, Katharine W

    2016-01-01

    Secondary school students in the United States continue to underachieve in mathematics and science. Improving teacher quality is a core component of improving student achievement. Here we report on a professional development program, the MAST System, that develops the knowledge and skills for teaching mathematics, including metacognitive knowledge and regulation. In this cognitive apprenticeship program, teachers learn to plan, evaluate and adjust to improve student engagement and achievement. Central is the metacognitive practice of defense of instruction. By practicing this reflective approach, teachers become adaptive experts, able to innovate in the classroom. During the two-year intervention, the MAST System resulted in large increases in the California Standards Test mathematics scores, compared to both the district and the state. In addition, improvement continued for several years after the intervention was completed. This continued improvement in student scores indicated that the teachers and schools...

    2008-01-01

    We study the networking effects on the population divergence and the increased level of cooperation in the continuous snowdrift game (CSG). In the regular world, limited interaction inhibits the occurrence of evolutionary branching. The formation of clusters defends the intermediate-investors from intruding by high- or low-investors. In a rewired network, the collective behaviour is related to the rewiring rules. A linear relationship I = ασ + b between the average investment and the standard deviation of the degree distribution is found.

  19. Continuous quality improvement of colorectal cancer screening

    Mariusz; Madalinski

    2013-01-01

    Quality assurance is a key issue in colorectal cancer screening, because effective screening is able to improve primary prevention of the cancer. The quality measure may be described in terms:how well the screening test tells who truly has a disease (sensitivity) and who truly does not have a disease (specificity). This paper raises concerns about identification of the optimal screening test for colorectal cancer. Colonoscopy vs flexible sigmoidoscopy in colorectal cancer screening has been a source of ongoing debate. A multicentre randomised controlled trial comparing flexible sigmoidoscopy with usual care showed that flexible sigmoidoscopy screening is able to diminish the incidence of distal and proximal colorectal cancer, and also mortality related to the distal colorectal cancer. However, colonoscopy provides a more complete examination and remains the more sensitive exam than flexible sigmoidoscopy. Moreover, colonoscopy with polypectomy significantly reduces colorectal cancer incidence and colorectal cancer-related mortality in the general population. The article considers the relative merits of both methods and stresses an ethical aspect of patient’s involvement in decision-making. Patients should be informed not only about tests tolerability and risk of endoscopy complications, but also that different screening tests for bowel cancer have different strength to exclude colonic cancer and polyps. The authorities calculate effectiveness and costs of the screening tests, but patients may not be interested in statistics regarding flexible sigmoidoscopy screening and from an ethical point of view, they have the right to chose colonoscopy, which is able to exclude a cancer and precancerous lesions in the whole large bowel.

  20. La Hague Continuous Improvement Program: Enhancement of the Vitrification Throughput

    The vitrification of high-level liquid waste produced from nuclear fuel reprocessing has been carried out industrially for over 25 years by AREVA/COGEMA, with two main objectives: containment of the long lived fission products and reduction of the final volume of waste. At the 'La Hague' plant, in the 'R7' and 'T7' facilities, vitrified waste is obtained by first evaporating and calcining the nitric acid feed solution-containing fission products in calciners. The product-named calcinate- is then fed together with glass frit into induction-heated metallic melters to produce the so-called R7/T7 glass, well known for its excellent containment properties. Both facilities are equipped with three processing lines. In the near future the increase of the fuel burn-up will influence the amount of fission product solutions to be processed at R7/T7. As a consequence, in order to prepare these changes, it is necessary to feed the calciner at higher flow-rates. Consistent and medium-term R and D programs led by CEA (French Atomic Energy Commission, the AREVA/COGEMA's R and D and R and T provider), AREVA/COGEMA (Industrial Operator) and AREVA/SGN (AREVA/COGEMA's Engineering), and associated to the industrial feed back of AREVA/COGEMA operations, have allowed continuous improvement of the process since 1998: - The efficiency and limitation of the equipment have been studied and solutions for technological improvements have been proposed whenever necessary, - The increase of the feeding flow-rate has been implemented on the improved CEA test rig (so called PEV, Evolutional Prototype of Vitrification) and adapted by AREVA/SGN for the La Hague plant using their modeling studies; the results obtained during this test confirmed the technological and industrial feasibility of the improvements achieved, - After all necessary improved equipments have been implemented in R7/T7 facilities, and a specific campaign has been performed on the R7 facility by AREVA/COGEMA.

  3. [Continuous nursing education to improve the quality of health care].

    Fumić, Nera; Marinović, Marin; Brajan, Dolores

    2014-10-01

    Health care and today's medical and technical achievements and approved standards of treatment provide comprehensive quality, safety and traceability of medical procedures respecting the principles of health protection. Continuous education improves the quality of nursing health care and increases the effectiveness of patient care, consequently maintaining and enhancing patient safety. Patient health problems impose the need of appropriate, planned and timely nursing care and treatment. In providing quality nursing care, attention is focused on the patient and his/her needs in order to maintain and increase their safety, satisfaction, independence and recovery or peaceful death, so the health and nursing practices must be systematized, planned and based on knowledge and experience. Health and nursing care of patients at risk of developing acute and chronic wounds or already suffering from some form of this imply preventive measures that are provided through patient education, motivation, monitoring, early recognition of risk factors and causes, and reducing or removing them through the prescribed necessary medical treatment which is safe depending on the patient health status. Except for preventive measures, nursing care of patients who already suffer from some form of acute or chronic wounds is focused on the care and treatment of damaged tissue by providing appropriate and timely diagnosis, timely and proper evaluation of the wound and patient general status, knowledge and understanding of the wide range of local, oral and parenteral therapy and treatment, aiming to increase patient safety by preventing progression of the patient general condition and local wound status and reducing the possibility of developing infection or other complications of the underlying disease. In the overall patient management, through nursing process, medical interventions are implemented and aimed to maintain and optimize health status, prevent complications of existing diseases and

  5. Microalloying Boron Carbide with Silicon to Achieve Dramatically Improved Ductility.

    An, Qi; Goddard, William A

    2014-12-01

    Boron carbide (B4C) is a hard material whose value for extended engineering applications such as body armor; is limited by its brittleness under impact. To improve the ductility while retaining hardness, we used density functional theory to examine modifying B4C ductility through microalloying. We found that replacing the CBC chain in B4C with Si-Si, denoted as (B11Cp)-Si2, dramatically improves the ductility, allowing a continuous shear to a large strain of 0.802 (about twice of B4C failure strain) without brittle failure. Moreover, (B11C)-Si2 retains low density and high hardness. This ductility improvement arises because the Si-Si linkages enable the icosahedra accommodate additional shear by rotating instead of breaking bonds. PMID:26278950

  12. Teacher Tweets Improve Achievement for Eighth Grade Science Students

    Carol Van Vooren

    2013-02-01

    Full Text Available In the Digital Age teachers have fallen far behind the technical skills of their "digital native" students. The implementation of technology as a tool for classroom communication is foreign for most teachers, but highly preferred by students. While teenagers are using Facebook, Twitter, and other social networks to communicate, teachers continue to respond through face-to-face conversations, telephone calls, and email messaging. Twitter, a platform for short message service text, is an online social network site that allows users to send and receive messages using 140 characters or less called Tweets. To analyze the relationship of the teacher's use of Twitter with student academic achievement, a correlation study conducted by Bess collected data from two matched samples of eighth grade science students: one utilizing Twitter and one not utilizing Twitter to reinforce classroom instruction. Two tests matching the science standards were given to both samples of students. The results of the tests were used as primary data. The findings suggested a positive correlation between the use of Twitter and student performance on the standardized tests. Implications for this study indicate that young teenagers may prefer Twitter as a mode of communication with their teacher, resulting in higher academic achievement in a middle school science class.

  18. Improving building energy system performance by continuous commissioning

    Liu, M. [Univ. of Nebraska, Omaha, NE (United States)

    1999-10-01

    Commissioning has played an important role in improved building comfort and reduced energy consumption. This article presents an advanced form of commissioning for existing buildings, called continuous commissioning (CC), which has produced energy savings comparable to those produced by the traditional audit/retrofit process at a third of the cost. It has also increased operating staff skills, reduced maintenance costs, and improved building comfort--extras which are not provided by usual retrofit programs. This article will present the philosophy, process, cost, and savings. Continuous commissioning is a process developed by the Energy Systems Laboratory (ESL) to: (1) optimize the operation of existing systems to improve building comfort and reduce building energy cost; (2) solve existing comfort and IAQ problems; (3) guarantee continuous optimal operation by operational staff in future years; and (4) provide optimal energy retrofit suggestions to owners to minimize the project costs.

Although team retrospectives have been prescribed and some practices have been introduced in order to implement and facilitate them, the truth is that most Agile teams are conducting dull retrospectives that end with a list of things that have been done wrong, just to repeat the same list two weeks later at the next meeting.Instead of listing hundreds of Japanese-la

  3. Design of launch systems using continuous improvement process

    Brown, Richard W.

    1995-01-01

    The purpose of this paper is to identify a systematic process for improving ground operations for future launch systems. This approach is based on the Total Quality Management (TQM) continuous improvement process. While the continuous improvement process is normally identified with making incremental changes to an existing system, it can be used on new systems if they use past experience as a knowledge base. In the case of the Reusable Launch Vehicle (RLV), the Space Shuttle operations provide many lessons. The TQM methodology used for this paper will be borrowed from the United States Air Force 'Quality Air Force' Program. There is a general overview of the continuous improvement process, with concentration on the formulation phase. During this phase critical analyses are conducted to determine the strategy and goals for the remaining development process. These analyses include analyzing the mission from the customers point of view, developing an operations concept for the future, assessing current capabilities and determining the gap to be closed between current capabilities and future needs and requirements. A brief analyses of the RLV, relative to the Space Shuttle, will be used to illustrate the concept. Using the continuous improvement design concept has many advantages. These include a customer oriented process which will develop a more marketable product and a better integration of operations and systems during the design phase. But, the use of TQM techniques will require changes, including more discipline in the design process and more emphasis on data gathering for operational systems. The benefits will far outweigh the additional effort.

  4. Building environmental assessment schemes: pragmatism to achieve meaningful improvements

    Burnett, J; Ling, L. W. [Hong Kong Polytechnic Univ., Hong Kong Special Administrative Region (China)

    1998-11-01

    The objective of the Hong Kong Building Environmental Assessment Method (HK-BEAM) is to minimize the adverse effects of new office premises on the global and local environment and to promote healthy indoor environments within reasonable additional costs. It is intended to encourage clients, designers, contractors, operators, and occupants to become more environmentally aware, and to reduce long-term impact that buildings have on the environment. Preliminary assessment of new offices is carried out during the design process, with follow-ups during construction and upon completion before confirming the overall assessment rating. The assessment method is designed to take into account global issues and use of resources. These include energy consumption, office lighting, heat recovery, air conditioning, electricity consumption, ozone depletion, use of timber, storage for recycling of materials, etc. Local issues mentioned are electricity maximum demand, water conservation and waste water discharge, recycled materials, noise from cooling, noise from building services installation, vehicular and pedestrian access, etc. Indoor issues incorporate non-HVAC services, indoor air quality, hazardous materials, lighting design, daylighting, etc. In general, the HK-BEAM scheme has achieved good credibility within Hong Kong. It has improved the awareness of developers as far as environmental issues are concerned, encouraged better design and operational practices. Nevertheless, to date it has had no significant impact on the building stock overall. 8 refs., 2 tabs.

  5. Lean management systems: creating a culture of continuous quality improvement.

    Clark, David M; Silvester, Kate; Knowles, Simon

    2013-08-01

    This is the first in a series of articles describing the application of Lean management systems to Laboratory Medicine. Lean is the term used to describe a principle-based continuous quality improvement (CQI) management system based on the Toyota production system (TPS) that has been evolving for over 70 years. Its origins go back much further and are heavily influenced by the work of W Edwards Deming and the scientific method that forms the basis of most quality management systems. Lean has two fundamental elements--a systematic approach to process improvement by removing waste in order to maximise value for the end-user of the service and a commitment to respect, challenge and develop the people who work within the service to create a culture of continuous improvement. Lean principles have been applied to a growing number of Healthcare systems throughout the world to improve the quality and cost-effectiveness of services for patients and a number of laboratories from all the pathology disciplines have used Lean to shorten turnaround times, improve quality (reduce errors) and improve productivity. Increasingly, models used to plan and implement large scale change in healthcare systems, including the National Health Service (NHS) change model, have evidence-based improvement methodologies (such as Lean CQI) as a core component. Consequently, a working knowledge of improvement methodology will be a core skill for Pathologists involved in leadership and management. PMID:23757036

  9. Building a Culture of Continuous Quality Improvement in an Academic Radiology Department.

    Katzman, Gregory L; Paushter, David M

    2016-04-01

    As we enter a new era of health care in the United States, radiologists must be adequately prepared to prove, and continually improve, our value to our customers. This goal can be achieved in large part by providing high-quality services. Although quality efforts on the national and international levels provide a framework for improving radiologic quality, some of the greatest opportunities for quality improvement can be found at the departmental level, through the implementation of total quality management programs. Establishing such a program requires not only strong leadership and employee engagement, but also a firm understanding of the multiple total quality management tools and continuous quality improvement strategies available. In this article, we discuss key tools and strategies required to build a culture of continuous quality improvement in an academic department, based on our experience. PMID:26896936

  11. IMHEX fuel cell repeat component manufacturing continuous improvement accomplishments

    Jakaitis, L.A.; Petraglia, V.J.; Bryson, E.S. [M-C Power Corp., Burr Ridge, IL (United States)] [and others

    1996-12-31

    M-C Power is taking a power generation technology that has been proven in the laboratory and is making it a commercially competitive product. There are many areas in which this technology required scale up and refinement to reach the market entry goals for the IMHEX{reg_sign} molten carbonate fuel cell power plant. One of the primary areas that needed to be addressed was the manufacturing of the fuel cell stack. Up to this point, the fuel cell stack and associated components were virtually hand made for each system to be tested. M-C Power has now continuously manufactured the repeat components for three 250 kW stacks. M-C Power`s manufacturing strategy integrated both evolutionary and revolutionary improvements into its comprehensive commercialization effort. M-C Power`s objectives were to analyze and continuously improve stack component manufacturing and assembly techniques consistent with established specifications and commercial scale production requirements. Evolutionary improvements are those which naturally occur as the production rates are increased and experience is gained. Examples of evolutionary (learning curve) improvements included reducing scrap rates and decreasing raw material costs by buying in large quantities. Revolutionary improvements result in significant design and process changes to meet cost and performance requirements of the market entry system. Revolutionary changes often involve identifying new methods and developing designs to accommodate the new process. Based upon our accomplishments, M-C Power was able to reduce the cost of continuously manufactured fuel cell repeat components from the first to third 250 kW stack by 63%. This paper documents the continuous improvement accomplishments realized by M-C Power during IMHEX{reg_sign} fuel cell repeat component manufacturing.

  13. How to Sustain Change and Support Continuous Quality Improvement.

    Silver, Samuel A; McQuillan, Rory; Harel, Ziv; Weizman, Adam V; Thomas, Alison; Nesrallah, Gihad; Bell, Chaim M; Chan, Christopher T; Chertow, Glenn M

    To achieve sustainable change, quality improvement initiatives must become the new way of working rather than something added on to routine clinical care. However, most organizational change is not maintained. In this next article in this Moving Points in Nephrology feature on quality improvement, we provide health care professionals with strategies to sustain and support quality improvement. Threats to sustainability may be identified both at the beginning of a project and when it is ready for implementation. The National Health Service Sustainability Model is reviewed as one example to help identify issues that affect long-term success of quality improvement projects. Tools to help sustain improvement include process control boards, performance boards, standard work, and improvement huddles. Process control and performance boards are methods to communicate improvement results to staff and leadership. Standard work is a written or visual outline of current best practices for a task and provides a framework to ensure that changes that have improved patient care are consistently and reliably applied to every patient encounter. Improvement huddles are short, regular meetings among staff to anticipate problems, review performance, and support a culture of improvement. Many of these tools rely on principles of visual management, which are systems transparent and simple so that every staff member can rapidly distinguish normal from abnormal working conditions. Even when quality improvement methods are properly applied, the success of a project still depends on contextual factors. Context refers to aspects of the local setting in which the project operates. Context affects resources, leadership support, data infrastructure, team motivation, and team performance. For these reasons, the same project may thrive in a supportive context and fail in a different context. To demonstrate the practical applications of these quality improvement principles, these principles are

  14. Continuous improvement program in ENUSA: personnel participation and six sigma

    Since the beginning of its activities ENUSA has been a company committed with the quality of its products and services. To talk about quality is something inherent in ENUSA's daily work ENUSA's position in the market depends on its capacity to satisfy customers expectations with the best products and services, as a result of an efficient management of its processes. The word quality in its broadest sense, means that any activity can be improved. ENUSA has implemented a continuous improvement program as part of its company change project. That program consists of six basic steps: 1.- Managers commitment. 2.- Organization for continuous improvement. 3.- Quality goals. 4.- Training and informing. 5.- Personnel participation. 6.- Methodology. ENUSA has introduced these six steps during 1997-98 period. It is important to point out the commitment degree at all the company levels, focusing the organization to the continuous improvement in a multifunctional way, following the business processes: - Board of Directors - Quality Steering Committee - Quality Improvement Groups (GMC) - Quality Operative Groups (GOC) - Suggestions Mailboxes The following GMC's have been set up and are operative. - Manufacturing GMC - Supplies GMC - Installation GMC - Design GMC - Quality System GM - Projects GMC - Administrative GMC These GMC's have established thirty-six Quality Operative Groups which carry out the improvement projects. The methodology chosen by ENUSA is known as ''SIX SIGMA''. Six sigma programs have proved their huge power in big companies as MOTOROLA and, recently, GE being recognized in all the quality fields. It is, by itself, a change program in which a quality improvement methods is structured with an excellent view of processes, products and services. (Author)

  15. Successful integration of ergonomics into continuous improvement initiatives.

    Monroe, Kimberly; Fick, Faye; Joshi, Madina

    2012-01-01

    Process improvement initiatives are receiving renewed attention by large corporations as they attempt to reduce manufacturing costs and stay competitive in the global marketplace. These initiatives include 5S, Six Sigma, and Lean. These programs often take up a large amount of available time and budget resources. More often than not, existing ergonomics processes are considered separate initiatives by upper management and struggle to gain a seat at the table. To effectively maintain their programs, ergonomics program managers need to overcome those obstacles and demonstrate how ergonomics initiatives are a natural fit with continuous improvement philosophies.

  17. Community-University Partnerships: Achieving continuity in the face of change

    Linda Silka

    2008-09-01

    Full Text Available A challenge that community-university partnerships everywhere will face is how to maintain continuity in the face of change. The problems besetting communities continually shift and the goals of the university partners often fluctuate. This article describes a decade-long strategy one university has successfully used to address this problem. Over the past ten years, a community-university partnership at the University of Massachusetts Lowell has used summer content funding to respond creativity to shifting priorities. Each summer a research-action project is developed that targets a different content issue that has emerged with unexpected urgency. Teams of graduate students and high school students are charged with investigating this issue under the auspices of the partnership. These highly varied topics have included immigrant businesses, youth asset mapping, women owned businesses, the housing crisis, social program cutbacks, sustainability, and economic development and the arts. Despite their obvious differences, these topics share underlying features that further partnership commitment and continuity. Each has an urgency: the information is needed quickly, often because some immediate policy change is under consideration. Each topic has the advantage of drawing on multiple domains: the topics are inherently interdisciplinary and because they do not “belong” to any single field, they lend themselves to disciplines pooling their efforts to achieve greater understanding. Each also has high visibility: their salience has meant that people were often willing to devote scarce resources to the issues and also that media attention could easily be gained to highlight the advantages of students, partners, and the university working together. And the topics themselves are generative: they have the potential to contribute in many different ways to teaching, research, and outreach. This paper ends with a broader consideration of how partnerships can

  18. Paths to continuous improvement of a CRM strategy

    Lluís G. Renart

    2008-07-01

    Full Text Available The concept of relationship marketing has led to a paradigm change in marketing. Over the last few decades, numerous studies have analyzed the impact of customer relationship management (CRM programs on customer satisfaction and loyalty. Quite a few CRM programs have been found to have little or no impact. Having already published several articles and cases on the subject, in this paper we set out to answer the following question: assuming a company already has a reasonably successful CRM strategy in place, how can it continuously adapt and improve that strategy? Our recommendation is that such companies implement a continuous improvement process at four different but complementary levels: first, review and reinforce the company’s mission, culture and values; second, reconsider and, if necessary, redesign the CRM strategy; third, manage the various relationship-building activities more effectively; and lastly, review and, if necessary, improve the quality of material and human resources, program execution and process governance. A systematic review of these four levels or “paths” of improvement should help generate and maintain high quality relationships over time.

  19. Improving Our Odds: Success through Continuous Risk Management

    Greenhalgh, Phillip O.

    2009-01-01

    Launching a rocket, running a business, driving to work and even day-to-day living all involve some degree of risk. Risk is ever present yet not always recognized, adequately assessed and appropriately mitigated. Identification, assessment and mitigation of risk are elements of the risk management component of the "continuous improvement" way of life that has become a hallmark of successful and progressive enterprises. While the application of risk management techniques to provide continuous improvement may be detailed and extensive, the philosophy, ideals and tools can be beneficially applied to all situations. Experiences with the use of risk identification, assessment and mitigation techniques for complex systems and processes are described. System safety efforts and tools used to examine potential risks of the Ares I First Stage of NASA s new Constellation Crew Launch Vehicle (CLV) presently being designed are noted as examples. Recommendations from lessons learned are provided for the application of risk management during the development of new systems as well as for the improvement of existing systems. Lessons learned and suggestions given are also examined for applicability to simple systems, uncomplicated processes and routine personal daily tasks. This paper informs the reader of varied uses of risk management efforts and techniques to identify, assess and mitigate risk for improvement of products, success of business, protection of people and enhancement of personal life.

  20. Continuous improvement of the BNFL transport integrated management system

    The integrated Management System of BNFL Transport and Pacific Nuclear Transport Limited (PNTL) is subject to continuous improvement by the application of established improvement techniques adopted by BNFL. The technique currently being used is the application of a Total Quality Management (TQM) philosophy, involving the identification of key processes, benchmarking against existing measures, initiating various improvement projects and applying process changes within the Company. The measurement technique being used is based upon the European Foundation for Quality Management Model (EFQM). A major initiative was started in 1996 to include the requirements of the Environmental Management Systems standard ISO 14001 within the existing integrated management system. This resulted in additional activities added to the system, modification to some existing activities and additional training for personnel. The system was audited by a third party certification organisation, Lloyds Register Quality Assurance (LRQA), during 1997. This paper describes the arrangements to review and update the integrated management system of BNFL Transport and PNTL to include the requirements of the environmental standard ISO 14001 and it also discusses the continuous improvement process adopted by BNFL Transport.

  2. R and D techniques and how to continuously improve them?

    Although decommissioning of nuclear installations has been carried out successfully in different countries, and decommissioning is sometimes considered as a mature industrial activity, Research and Development can still improve the operations, and is also needed to keep the current know how. The research and development can bring reduction of costs, limitation of radioactive waste generation, and improve the safety and radioprotection aspects. When one consider that less than 100 facilities are currently in decommissioning for more than 800 reactors (power plants and research reactors, almost half and half) worldwide, the present used technology can be considered as the prehistory of D and D. The paper will focus on the needs for improvements and developments, on the attached constraints and restriction, and will then look at the potential ways to continue R and D and technology improvement. Regarding the rather recent development of the D and D technology and the large remaining market for D and D of nuclear installations, there is still a large field of open development for techniques and technologies for the dismantling of nuclear installations worldwide. Although D and D of all kinds of nuclear installations have proven to be feasible, improvements are surely needed to reduce the costs and waste of D and D, therefore reducing the burden to the plant owners, and to improve the radioprotection of the operations. The same applies for the improvement of the overall operators safety during such operations. There are different ways to go in this direction and the groups to gather the necessary experience and technological data are existing, but the will has to be present to go forward, in a competitive environment. It is difficult to believe that such improvements in the technologies and the approach of decommissioning can rely only on commercial and private initiatives. Therefore, organized international R and D should be promoted wherever it is possible, enhancing

  3. A SELF PROCESS IMPROVEMENT FOR ACHIEVING HIGH SOFTWARE QUALITY

    DR. SHASHANK.D.JOSHI

    2011-05-01

    Full Text Available Quality has been one of the most important factors in judging any product. Quality means “a degree or grade of excellence or worth”. Quality is a term that is usually described using adjectives. Quality has several attributes to it, some of which can be quantified using metrics. These attributes such as usability, portability, security, performance, reliability etc have different importance in different projects. Different software quality assurance methods & practices have been used in different software projects to attain the true value. Quality is an attribute which is a distinct feature and it differs with people’s perception. Achieving high software quality involves measurement of software metrics and optimization based on estimated values. As the software systems grow larger, complexity ofdesign and implementation increases, and this in turn is more prone to defects and hence directly affect the quality of the systems. However, in any software project, high quality is always desirable, and many projects have specific quality requirements. Achieving high software quality involves measurement of software metrics and optimization based on estimated values. Developing high quality software is governed by factors such as people, process, technology and cost. This paper attempts to present a novel approach towards achieving high software quality in various kinds of projects under given constraints.

  5. Quality-control analytical methods: continuous quality improvement.

    Venti, Eden M

    2006-01-01

    It is vital that all compounding pharmacies have a continuous quality improvement program in place by way of standard operating procedures to assure that patients receive high-quality preparations. The program should take into consideration any federal and state regulatory requirements, as well as professional association expectations. Quality control measurements and regular review of those measurements are the foundations of a good quality plan. All pharmacy personnel should be aware of the importance of reporting potential internal quality concerns or problems and should be encouraged to do so without fear of repercussions. Ideally, an error-free compounding pracitice would be the goal. Since this is not practical, quality issues should not be viewed as problems, but as opportunities to improve compounding practices by correcting, before they become pervasive, the processes used in the preparation of prescriptions.

  6. Continued Development and Improvement of Pneumatic Heavy Vehicles

    Robert J. Englar

    2005-07-15

    The objective of this applied research effort led by Georgia Tech Research Institute is the application of pneumatic aerodynamic technology previously developed and patented by us to the design of an appropriate Heavy Vehicle (HV) tractor-trailer configuration, and experimental confirmation of this pneumatic configuration's improved aerodynamic characteristics. In Phases I to IV of our previous DOE program (Reference 1), GTRI has developed, patented, wind-tunnel tested and road-tested blown aerodynamic devices for Pneumatic Heavy Vehicles (PHVs) and Pneumatic Sports Utility Vehicles (PSUVs). To further advance these pneumatic technologies towards HV and SUV applications, additional Phase V tasks were included in the first year of a continuing DOE program (Reference 2). Based on the results of the Phase IV full-scale test programs, these Phase V tasks extended the application of pneumatic aerodynamics to include: further economy and performance improvements; increased aerodynamic stability and control; and safety of operation of Pneumatic HVs. Continued development of a Pneumatic SUV was also conducted during the Phase V program. Phase V was completed in July, 2003; its positive results towards development and confirmation of this pneumatic technology are reported in References 3 and 4. The current Phase VI of this program was incrementally funded by DOE in order to continue this technology development towards a second fuel economy test on the Pneumatic Heavy Vehicle. The objectives of this current Phase VI research and development effort (Ref. 5) fall into two categories: (1) develop improved pneumatic aerodynamic technology and configurations on smaller-scale models of the advanced Pneumatic Heavy Vehicle (PHV); and based on these findings, (2) redesign, modify, and re-test the modified full-scale PHV test vehicle. This second objective includes conduct of an on-road preliminary road test of this configuration to prepare it for a second series of SAE Type

  8. Steam generator replacement: a story of continuous improvement

    This paper provides a review of the history of steam generator replacement in the US focusing on the last five years. From the early replacements in the 1980s, there have been major technology improvements resulting in dramatically shorter outages and reduced radiological exposure for workers. Even though the changes for the last five years have been less dramatic, the improvement trend continues. No two steam generator replacement (SGR) projects are the same and there are some major differences including; the access path for the components to containment (is a construction opening in containment required), type of containment, number of steam generators, one piece or two piece replacement, plant type (Westinghouse, CE or B and W) and plant layout. These differences along with other variables such as delays due to plant operations and other activities not related to the steam generator replacement make analysis of performance data difficult. However, trends in outage performance and owner expectations can be identified. How far this trend will go is also discussed. Along with the trend of improved performance, there is also a significant variation in performance. Some of the contributors to this variation are identified. This paper addresses what is required for a successful outage, meeting the increasing expectations and setting new records. The authors will discuss various factors that contribute to the success of a steam generator replacement. These factors include technical issues and, equally important, organizational interface and the role the customer plays. Recommendations are provided for planning a successful steam generator replacement outage. (author)

  9. Modification of provider behavior to achieve improved asthma outcomes.

    Jones, Erika M; Portnoy, Jay M

    2003-11-01

    Despite an abundance of scientific evidence supporting the use of guidelines, adherence to asthma practice guidelines by physicians generally is low, regardless of provider and patient characteristics. As a result, scientific information, obtained with great effort and at huge expense, is not being translated into clinical practice. To remedy this, we developed a disease management program that emphasizes alteration of provider behavior using operant conditioning. We did this by placing asthma educators in private offices for up to 8 weeks. The educators used a combination of problem-based learning, role modeling, and operant conditioning with positive reinforcement to affect behavior change. As a result of these behavior changes, by the end of 8 weeks the cost to treat asthma patients decreased, despite an increase in the cost of medications. We concluded that behavior-oriented programs targeted at provider offices can lead to improved asthma care while reducing costs. PMID:14531969

In February 2009 is noteworthy because the World Association of Nuclear Operators we identified as a learning organization, qualification which shows that the continuous improvement system has matured, and this system will expose as I get to learn to capitalize on our own experiences and external experiences diffused by the nuclear industry. In 2007 the management of nuclear power plants integrates its improvement systems and calls it continuous improvement system and is presented in the same extensive report that won the National Quality Award. This system is made up of 5 subsystems operating individually and are also related 1) human performance; 2) referential comparison or benchmarking; 3) self-assessment; 4) corrective action and 5) external operating experience. Five subsystems that plan, generate, capture, manage, communicate and protect the knowledge generated during the processes execution of nuclear power plant of Laguna Verde, as well as from external sources. The target set in 2007 was to increase the intellectual capital to always give response to meeting the security requirements, but creating a higher value to quality, customer, environment protection and society. In brief each of them, highlighting the objective, expectations management, implementation and some benefits. At the end they will describe two study cases selected to illustrate these cases as the organization learns by their continuous improvement system. (Author)

  12. Implementing a customer focused continual business improvement program to improve the maintenance process

    Global market pressures and increasing competition demands that successful companies establish a continual business improvement program as part of implementing its business strategy. Such programs must be driven by the definition of quality from the customer's perspective. This customer quality focus often requires a change in all aspects of the business including products, services, processes and culture. This paper will describe how Atomic Energy of Canada Limited implemented a Continual Business Improvement Program in their Nuclear Laboratories Business Unit. In particular, to review how the techniques were applied to improve the maintenance process and the status of the project. Customer (internal users of the processes at CRL) feedback has shown repeatedly there is dissatisfaction of the maintenance process.

    Introduction Continuing Medical Education (CME) has been considered as a lifelong commitment for doctors to provide the optimal care for patients. Despite a long history of creating CME programs, outcomes are far from ideal. The present qualitative study aims to clarify the barriers affecting effectiveness of the CME programs in Iran based on the experiences of general practitioners. Methods Sixteen general practitioners were recruited to participate in in-depth interviews and field observations concerning experiences with CME. The study was performed using a qualitative content analysis method. The codes, categories and themes were explored through an inductive process in which the researchers moved from specific to general. Results The participants’ experiences identified a number of barriers, particularly insufficient interaction with the instructors; additional problems included the teachers’ use of an undifferentiated approach; unreal and abstract CME; and ignorance of the diverse reasons to participate in CME. Conclusion Based on the study results, there are multiple barriers to effective implementation of CME in Iran. The key barriers include insufficient interaction between the trainees and providers, which must be considered by other stakeholders and program designers. Such interactions would facilitate improved program design, invite more specific tailoring of the education to the participants, allow for more effective educational methods and set the stage for outcome evaluation from the learners actually applying their new knowledge in practice. Replication of these findings with another sample would improve confidence in these recommendations, but these findings are broadly consistent with findings in the educational literature on improving the efficacy of CME.

  14. Improved Continuous-Time Higher Harmonic Control Using Hinfinity Methods

    Fan, Frank H.

    The helicopter is a versatile aircraft that can take-off and land vertically, hover efficiently, and maneuver in confined space. This versatility is enabled by the main rotor, which also causes undesired harmonic vibration during operation. This unwanted vibration has a negative impact on the practicality of the helicopter and also increases its operational cost. Passive control techniques have been applied to helicopter vibration suppression, but these methods are generally heavy and are not robust to changes in operating conditions. Feedback control offers the advantages of robustness and potentially higher performance over passive control techniques, and amongst the various feedback schemes, Shaw's higher harmonic control algorithm has been shown to be an effective method for attenuating harmonic disturbance in helicopters. In this thesis, the higher harmonic disturbance algorithm is further developed to achieve improved performance. One goal in this thesis is to determine the importance of periodicity in the helicopter rotor dynamics for control synthesis. Based on the analysis of wind tunnel data and simulation results, we conclude the helicopter rotor can be modeled reasonably well as linear and time-invariant for control design purposes. Modeling the helicopter rotor as linear time-invariant allows us to apply linear control theory concepts to the higher harmonic control problem. Another goal in this thesis is to find the limits of performance in harmonic disturbance rejection. To achieve this goal, we first define the metrics to measure the performance of the controller in terms of response speed and robustness to changes in the plant dynamics. The performance metrics are incorporated into an Hinfinity control problem. For a given plant, the resulting Hinfinity controller achieves the maximum performance, thus allowing us to identify the performance limitation in harmonic disturbance rejection. However, the Hinfinity controllers are of high order, and may

  17. Six Years Into Its Mission, NASA's Chandra X-ray Observatory Continues to Achieve Scientific Firsts

    2005-08-01

    In August 1999, NASA's Chandra X-ray Observatory opened for business. Six years later, it continues to achieve scientific firsts. "When Chandra opened its sunshade doors for the first time, it opened the possibility of studying the X-ray emission of the universe with unprecedented clarity," said Chandra project scientist Dr. Martin Weisskopf of NASA's Marshall Space Flight Center in Huntsville, Ala. "Already surpassing its goal of a five-year life, Chandra continues to rewrite textbooks with discoveries about our own solar system and images of celestial objects as far as billions of light years away." Based on the observatory's outstanding results, NASA Headquarters in Washington decided in 2001 to extend Chandra s mission from five years to ten. During the observatory s sixth year of operation, auroras from Jupiter, X-rays from Saturn, and the early days of our solar system were the focus of Chandra discoveries close to home -- discoveries with the potential to better understand the dynamics of life on Earth. Jupiter's auroras are the most spectacular and active auroras in the solar system. Extended Chandra observations revealed that Jupiter s auroral X-rays are caused by highly charged particles crashing into the atmosphere above Jupiter's poles. These results gave scientists information needed to compare Jupiter's auroras with those from Earth, and determine if they are triggered by different cosmic and planetary events. Mysterious X-rays from Saturn also received attention, as Chandra completed the first observation of a solar X-ray flare reflected from Saturn's low-latitudes, the region that correlates to Earth's equator and tropics. This observation led scientists to conclude the ringed planet may act as a mirror, reflecting explosive activity from the sun. Solar-storm watchers on Earth might see a surprising benefit. The results imply scientists could use giant planets like Saturn as remote-sensing tools to help monitor X-ray flaring on portions of the sun

  18. A formula for continued improvement: Audit follow-up

    In his book Management Audits, Allan J. Sayle states, ''QA standards stipulate that corrective action, required as a result of performing an audit, be followed up and closed out. There would, indeed, be little point in performing audits, requiring corrective action, or having a QA system at all if the auditee knows that the auditor will never verify that the corrective action has been efficaciously implemented.'' The QA auditor has an obligation to include follow-up in the overall audit planning. All too often the auditor will go to great lengths to plan and perform an audit only to have a recurring finding in the next audit. The proposed corrective action was only promissory and was not designed to stop the problem from recurring or to identify its root cause. Auditors do a disservice to the overall QA program and particularly to the customer when they fail to follow up and verify that an audit corrective action has been effectively implemented. In this paper, the techniques used by the quality assurance auditors at the Pacific Northwest Laboratory (PNL) will be presented. Although PNL is a research and development laboratory, the techniques outlined in this paper could be applied to any industry conducting quality assurance audits. Most important, they provide a formula for continued improvement by assuring that audit follow-up is timely, meaningful, and permanent

  20. Continued SOFC cell and stack technology and improved production methods

    Wandel, M.; Brodersen, K.; Phair, J. (and others)

    2009-05-15

    Within this project significant results are obtained on a number of very diverse areas ranging from development of cell production, metallic creep in interconnect to assembling and test of stacks with foot print larger than 500 cm2. Out of 38 milestones 28 have been fulfilled and 10 have been partly fulfilled. This project has focused on three main areas: 1) The continued cell development and optimization of manufacturing processes aiming at production of large foot-print cells, improving cell performance and development environmentally more benign production methods. 2) Stack technology - especially stacks with large foot print and improving the stack design with respect to flow geometry and gas leakages. 3) Development of stack components with emphasis on sealing (for 2G as well as 3G), interconnect (coat, architecture and creep) and test development. Production of cells with a foot print larger than 500 cm2 is very difficult due to the brittleness of the cells and great effort has been put into this topic. Eight cells were successfully produced making it possible to assemble and test a real stack thereby giving valuable results on the prospects of stacks with large foot print. However, the yield rate is very low and a significant development to increase this yield lies ahead. Several lessons were learned on the stack level regarding 'large foot print' stacks. Modelling studies showed that the width of the cell primarily is limited by production and handling of the cell whereas the length (in the flow direction) is limited by e.g. pressure drop and necessary manifolding. The optimal cell size in the flow direction was calculated to be between approx20 cm and < 30 cm. From an economical point of view the production yield is crucial and stacks with large foot print cell area are only feasible if the cell production yield is significantly enhanced. Co-casting has been pursued as a production technique due to the possibilities in large scale production

  2. Achieving Continuity of Care: Facilitators and Barriers in Community Mental Health Teams

    Jones Ian Rees

    2011-03-01

    Full Text Available Abstract Background The integration of mental health and social services for people diagnosed with severe mental illness (SMI has been a key aspect of attempts to reform mental health services in the UK and aims to minimise user and carer distress and confusion arising from service discontinuities. Community mental health teams (CMHTs are a key component of UK policy for integrated service delivery, but implementing this policy has raised considerable organisational challenges. The aim of this study was to identify and explore facilitators and barriers perceived to influence continuity of care by health and social care professionals working in and closely associated with CMHTs. Methods This study employed a survey design utilising in-depth, semi-structured interviews with a proportionate, random sample of 113 health and social care professionals and representatives of voluntary organisations. Participants worked in two NHS Mental Health Trusts in greater London within eight adult CMHTs and their associated acute in-patient wards, six local general practices, and two voluntary organisations. Results Team leadership, decision making, and experiences of teamwork support were facilitators for cross boundary and team continuity; face-to-face communication between teams, managers, general practitioners, and the voluntary sector were facilitators for information continuity. Relational, personal, and longitudinal continuity were facilitated in some local areas by workforce stability. Barriers for cross boundary and team continuity were specific leadership styles and models of decision making, blurred professional role boundaries, generic working, and lack of training for role development. Barriers for relational, personal, and longitudinal continuity were created by inadequate staffing levels, high caseloads, and administrative duties that could limit time spent with users. Incompatibility of information technology systems hindered information

  4. X-rays taken by radiologists. Influence on a continuous quality improvement process?

    Purpose: To evaluate how the training of radiology residents in taking radiographs influences the work of radiographers and the established quality standards. Methods: A first year radiology resident was trained for 4 weeks in focusing and exposure techniques by radiographers. In a second period the resident took 582 radiograms, which were compared with those taken by technicians for error estimation on a daily basis. During a third period the radiographs were produced in a contest between the resident and a skilled radiographer. Errors were analysed by two independent experts according to established guidelines of the German Medical Association. Results: At the beginning of the second period the average error rate of the resident was 11.9% as compared to 8.9% in the technicians team, in the following month 9.2% versus 15.9%. In the third period no relevant difference in errors could be observed. Finally, unexpected quality improvements were implemented like an improved standardization of focusing and exposure techniques as well as dose reduction. Conclusions: Radiology residents easily learn focusing and exposure techniques and achieve comparable results as radiographers within a short period of time. The additionally achieved knowledge improves the technical process of taking radiographs. We recommend to include a two plane radiography training period in the curriculum of radiology residents. It reinforces the radiologist's role in continuous quality improvements of the diagnostic process. (orig.)

  9. Modular Approach for Continuous Cell-Level Balancing to Improve Performance of Large Battery Packs: Preprint

    Muneed ur Rehman, M.; Evzelman, M.; Hathaway, K.; Zane, R.; Plett, G. L.; Smith, K.; Wood, E.; Maksimovic, D.

    2014-10-01

    Energy storage systems require battery cell balancing circuits to avoid divergence of cell state of charge (SOC). A modular approach based on distributed continuous cell-level control is presented that extends the balancing function to higher level pack performance objectives such as improving power capability and increasing pack lifetime. This is achieved by adding DC-DC converters in parallel with cells and using state estimation and control to autonomously bias individual cell SOC and SOC range, forcing healthier cells to be cycled deeper than weaker cells. The result is a pack with improved degradation characteristics and extended lifetime. The modular architecture and control concepts are developed and hardware results are demonstrated for a 91.2-Wh battery pack consisting of four series Li-ion battery cells and four dual active bridge (DAB) bypass DC-DC converters.

  11. Observations of human factors as a continuous improvement tool

    Principles for Excellence in Human Performance should promote behaviors throughout an organization that support safety and reliable operation of the plant. Such behaviors must be clearly defined, communicated and reinforced by managers, on a continuous basis. To identify if workers behaviors are in compliance with those expected is paramount to have an observations program in place, which in one hand identifies deviations from expectations to correct them, and on the other promotes the desired behaviors through positive reinforcement.

  12. Search for continuous gravitational waves: Improving robustness versus instrumental artifacts

    Keitel, D.; Prix, R.; Papa, M.; Leaci, P.; Siddiqi, M.

    2013-01-01

    The standard multidetector F-statistic for continuous gravitational waves is susceptible to false alarms from instrumental artifacts, for example monochromatic sinusoidal disturbances ('lines'). This vulnerability to line artifacts arises because the F-statistic compares the signal hypothesis to a Gaussian-noise hypothesis, and hence is triggered by anything that resembles the signal hypothesis more than Gaussian noise. Various ad-hoc veto methods to deal with such line artifacts have been pr...

  15. Improvement of Fibre Placement Accuracy in Continuous Tow Shearing Process

    Kim, Byung Chul; Zympeloudis, Evangelos D

    2015-01-01

    Automated Fibre Placement (AFP) is the state-of-the-art technology to produce complex composite aircraft parts. However, its main disadvantage is that it generally produces the process-induced defect such as fibre buckling in steering process, which is required to lay up the tow following non-geodesic paths on a complex mould. Continuous Tow Shearing (CTS) was developed to eliminate the fibre buckling by using the in-plane shear deformation of the tow material [1, 2]. The uniquely designed he...

  16. AN IMPROVED ANT COLONY ALGORITHM IN CONTINUOUS OPTIMIZATION

    Ling CHEN; Jie SHEN; Ling QIN; Hongjian CHEN

    2003-01-01

    A modified ant colony algorithm for solving optimization problem with continuous parameters is presented. In the method, groups of candidate values of the components are constructed, and each value in the group has its trail information. In each iteration of the ant colony algorithm, the method first chooses initial values of the components using the trail information. Then GA operations of crossover and mutation can determine the values of the components in the solution. Our experimental results on the problem of nonlinear programming show that our method has a much higher convergence speed and stability than those of simulated annealing (SA) and GA.

  17. 30% improvement in absorption spectroscopy detectivity achieved by the detuned loading of a quantum cascade laser.

    Michel, Florian; Juretzka, Carsten; Carras, Mathieu; Elsäßer, Wolfgang

    2014-11-01

    We perform a direct absorption spectroscopy experiment of carbon monoxide at 2193  cm(-1) by exploring the detectivity improvement potential of an intensity noise (IN)-reduced distributed feedback (DFB) quantum cascade laser. This was achieved by a detuned loading approach via a short, phase-sensitive optical feedback cavity. Under optimum IN reduction conditions, we obtain an improvement in signal-to-noise ratio from 733 to 1048, which transfers into a detection limit improvement from 1.2 ppm to 840 ppb. Therefore, we achieve a 30% lower detection limit, with the IN reduced when compared to the free-running case. PMID:25361352

  18. Improving training tools for continuing operator qualification in Spain

    There are currently nine nuclear power plants in service in Spain; the most recent started commercial operation in 1988. Spanish legislation requires operators to have an academic technical background of at least 3 yr. The turnover rate is <5%, and in recent years, symptom-based emergency procedure has been introduced. These facts have given rise to a situation in which Spanish licensed operators are demanding more in-depth training to avoid a stagnant routine and boredom. In responding to this challenge, Tecnatom has had to significantly update its two simulators for boiling water reactor (BWR) and pressurized water reactor (PSR) plants, to ensure coverage of the emergency procedures and has had to create a tool - the Interactive Graphics Simulator - that allows these problems to be ameliorated. With a view to updating its simulators, Tecnatom initiated in 1985 a project known as advanced simulation models (MAS), which was completed at the end of 1990. The TRACS code is a real-time advanced thermohydraulic code for upgrading Tecnatom's nuclear plant simulators. The interactive graphic simulator, (SGI) is a system that provides a graphic display of the models of a full-scope simulator by means of color monitors. The two new tools used are enabling higher levels of motivation to be achieved among the plant operations personnel, especially with respect to requalification

  19. Improving teleportation of continuous variables by local operations

    We study a continuous-variable (CV) teleportation protocol based on a shared entangled state produced by the quantum-nondemolition (QND) interaction of two vacuum states. The scheme utilizes the QND interaction or an unbalanced beam splitter in the Bell measurement. It is shown that in the nonunity gain regime the signal transfer coefficient can be enhanced while the conditional variance product remains preserved by applying appropriate local squeezing operation on sender's part of the shared entangled state. In the unity gain regime, it is demonstrated that the fidelity of teleportation can be increased with the help of the local squeezing operations on parts of the shared entangled state that effectively convert our scheme to the standard CV teleportation scheme. Further, it is proved analytically that such a choice of the local symplectic operations minimizes the noise by which the mean number of photons in the input state is increased during the teleportation. Finally, our analysis reveals that the local symplectic operation on sender's side can be integrated into the Bell measurement if the interaction constant of the interaction in the Bell measurement can be adjusted properly

  1. Improving the Syllable-Synchronous Network Search Algorithm for Word Decoding in Continuous Chinese Speech Recognition

    郑方; 武健; 宋战江

    2000-01-01

    The previously proposed syllable-synchronous network search (SSNS) algorithm plays a very important role in the word decoding of the continuous Chinese speech recognition and achieves satisfying performance. Several related key factors that may affect the overall word decoding effect are carefully studied in this paper, including the perfecting of the vocabulary, the big-discount Turing re-estimating of the N-Gram probabilities, and the managing of the searching path buffers. Based on these discussions, corresponding approaches to improving the SSNS algorithm are proposed. Compared with the previous version of SSNS algorithm, the new version decreases the Chinese character error rate (CCER) in the word decoding by 42.1% across a database consisting of a large number of testing sentences (syllable strings).

  7. The Big Improvement in PISA 2009 Reading Achievements in Serbia: Improvement of the Quality of Education or Something Else?

    Dragica Pavlović Babić

    2011-01-01

    Full Text Available The PISA 2009 results in Serbia show a big improvement in reading literacy compared to 2006 – the average score is 41 points higher, which is equal to the effect of a whole year of schooling in OECD countries and represents the second highest improvement ever recorded in a PISA study. In the present paper, we discuss potential reasons for such a big improvement based on analysis of the PISA 2009 reading achievements in different countries, with a special focus on countries from the same region (Croatia, Slovenia, Montenegro, Bulgaria, Romania and Albania. The analysis shows that the largest part of the improvement was realised at lower achieving levels, suggesting that the dominant method of teaching in schools is a traditional method oriented towards the acquisition and reproduction of academic knowledge. Findings of data analysis support the conclusion that the improvement is mainly the result of certain contextual factors, such as higher student motivation and a high level of official support for the PISA study in Serbia, rather than representing a real improvement in the quality of education.

    Active damping can be realised robustly through the use of a position actuator, a collocated force sensor, and control based on ‘Integral Force Feedback’ (IFF). Instead of a pure integrator, it is also possible to use a first-order lowpass-filter in the feedback loop (‘leaking IFF’). For both cases, the maximum achievable relative damping for a certain vibration mode can easily be predicted. If the achievable damping is too low, it is possible to improve this by means of ‘crosstalk-compensati...

  11. The efficacy of a continuous quality improvement (CQI) method in a radiological department: comparison with non-CQI control material

    To study the efficacy of continuous quality improvement (CQI) compared to ordinary management in an on-duty radiology department. Because of complaints regarding delivery of on-duty radiological services, an improvement was initiated simultaneously at two hospitals, at the HUCH (Helsinki University Central Hospital) utilising the CQI-method, and at the OUH (Oulu University Hospital) with a traditional management process. For the CQI project, a team was formed to evaluate the process with flow-charts, cause and effect diagrams, Pareto analysis and control charts. Interventions to improve the process were based on the results of these analyses. The team at the HUCH implemented the following changes: A radiologist was added to the evening shift between 15:00 - 22:00 and a radiographer was moved from the morning shift to 15:00 - 22:00. A clear improvement was achieved in the turn-around time, but in the follow-up some of the gains were lost. Only minimal changes were achieved at the OUH, where the intervention was based on traditional management processes. CQI was an effective method for improving the quality of performance of a radiology department compared with ordinary management methods, but some of this improvement may be subsequently lost without a continuous measurement system

    Ever shrinking measurement uncertainty requirements are difficult to achieve for a typical metrology toolset, especially over the entire expected life of the fleet. Many times, acceptable performance can be demonstrated during brief evaluation periods on a tool or two in the fleet. Over time and across the rest of the fleet, the most demanding processes often have measurement uncertainty concerns that prevent optimal process control, thereby limiting premium part yield, especially on the most aggressive technology nodes. Current metrology statistical process control (SPC) monitoring techniques focus on maintaining the performance of the fleet where toolset control chart limits are derived from a stable time period. These tools are prevented from measuring product when a statistical deviation is detected. Lastly, these charts are primarily concerned with daily fluctuations and do not consider the overall measurement uncertainty. It is possible that the control charts implemented for a given toolset suggest a healthy fleet while many of these demanding processes continue to suffer measurement uncertainty issues. This is especially true when extendibility is expected in a given generation of toolset. With this said, there is a need to continually improve the measurement uncertainty of the fleet until it can no longer meet the needed requirements at which point new technology needs to be entertained. This paper explores new methods in analyzing existing SPC monitor data to assess the measurement performance of the fleet and look for opportunities to drive improvements. Long term monitor data from a fleet of overlay and scatterometry tools will be analyzed. The paper also discusses using other methods besides SPC monitors to ensure the fleet stays matched; a set of SPC monitors provides a good baseline of fleet stability but it cannot represent all measurement scenarios happening in product recipes. The analyses presented deal with measurement uncertainty on non

    Aldowaisan, Tariq; Allahverdi, Ali

    2016-07-01

    This paper describes the process employed by the Industrial and Management Systems Engineering programme at Kuwait University to continuously improve the programme. Using a continuous improvement framework, the paper demonstrates how various qualitative and quantitative analyses methods, such as hypothesis testing and control charts, have been applied to the results of four assessment tools and other data sources to improve performance. Important improvements include the need to reconsider two student outcomes as they were difficult to implement in courses. In addition, through benchmarking and the engagement of Alumni and Employers, key decisions were made to improve the curriculum and enhance employability.

  15. An action research study; cultural differences impact how manufacturing organizations receive continuous improvement

    Kattman, Braden R.

    National culture and organizational culture impact how continuous improvement methods are received, implemented and deployed by suppliers. Previous research emphasized the dominance of national culture over organizational culture. The countries studied included Poland, Mexico, China, Taiwan, South Korea, Estonia, India, Canada, the United States, the United Kingdom, and Japan. The research found that Canada was most receptive to continuous improvement, with China being the least receptive. The study found that organizational culture was more influential than national culture. Isomorphism and benchmarking is driving continuous-improvement language and methods to be more universally known within business. Business and management practices are taking precedence in driving change within organizations.

  16. NUMBER OF SUCCESSIVE CYCLES NECESSARY TO ACHIEVE STABILITY OF SELECTED GROUND REACTION FORCE VARIABLES DURING CONTINUOUS JUMPING

    Jasmes M.W. Brownjohn

    2009-12-01

    Full Text Available Because of inherent variability in all human cyclical movements, such as walking, running and jumping, data collected across a single cycle might be atypical and potentially unable to represent an individual's generalized performance. The study described here was designed to determine the number of successive cycles due to continuous, repetitive countermovement jumping which a test subject should perform in a single experimental session to achieve stability of the mean of the corresponding continuously measured ground reaction force (GRF variables. Seven vertical GRF variables (period of jumping cycle, duration of contact phase, peak force amplitude and its timing, average rate of force development, average rate of force relaxation and impulse were extracted on the cycle-by-cycle basis from vertical jumping force time histories generated by twelve participants who were jumping in response to regular electronic metronome beats in the range 2-2.8 Hz. Stability of the selected GRF variables across successive jumping cycles was examined for three jumping rates (2, 2.4 and 2.8 Hz using two statistical methods: intra-class correlation (ICC analysis and segmental averaging technique (SAT. Results of the ICC analysis indicated that an average of four successive cycles (mean 4.5 ± 2.7 for 2 Hz; 3.9 ± 2.6 for 2.4 Hz; 3.3 ± 2.7 for 2.8 Hz were necessary to achieve maximum ICC values. Except for jumping period, maximum ICC values took values from 0.592 to 0.991 and all were significantly (p < 0.05 different from zero. Results of the SAT revealed that an average of ten successive cycles (mean 10.5 ± 3.5 for 2 Hz; 9.2 ± 3.8 for 2.4 Hz; 9.0 ± 3.9 for 2.8 Hz were necessary to achieve stability of the selected parameters using criteria previously reported in the literature. Using 10 reference trials, the SAT required standard deviation criterion values of 0.49, 0.41 and 0.55 for 2 Hz, 2.4 Hz and 2.8 Hz jumping rates, respectively, in order to approximate

  2. Emergency department triage: a program assessment using the tools of continuous quality improvement.

    Cook, S; Sinclair, D

    1997-01-01

    An assessment was undertaken in the emergency department of a busy tertiary care center to illustrate the role of continuous quality improvement in the evaluation of an emergency triage program that utilizes the emergency medical attendant to provide triage. An evaluation team interviewed triage staff, charge nurses, internal customers, risk management, and the patient representative. A detailed review of staff job descriptions, organization charts, orientation manual, and physical facilities was conducted. A chart audit was completed on 100 triage notes. Direct observation was undertaken on nine occasions. An evaluation of the data gathered was performed using the tools of continuous quality improvement, and resulted in specific recommendations being made to improve the process of care. It was concluded that emergency medical attendants function very well in an emergency medicine triage system and the tools of continuous quality improvement can be applied to a clinical service to improve the quality of care.

    Full Text Available Continuous Improvement Process started in LATU in 1996. The Impact was so important that covered all the organization. Nowadays LATU has almost all its processes certificated and most than 200 tests accredited. The Internal Audits process began in 1996 with an annual planning for all the laboratory's areas. For the UKAS accreditation in 1998, LATU improves the internal audits planning auditing not only the system but also the tests. In 1999 LATU was certified by SQS and accredited the calibrations by DKD. Since 2004 internal audits was managed as a process; in order to that was defined objectives, indicators, achievements and the necessary resources of the internal audit programme and process. The internal audit programme has a pre defined tri annual planning that includes all the laboratory areas. The results of the measures obtained till now demonstrate the improvement in the internal audit and all the laboratory processes. Auditors final staff increase their technical competence. As a consequence of managing the internal audits as a process, the internal communication has an important relevance to feedback the continuous improvement of the laboratory. This was evidence in a decrease of the documentaries non conformities, improvement of the calibrations and maintenance programme, optimization trainings and qualifications of the staff, common internal trainings, creation of a quality assurance team to improvement the tests control, improvement in the relationship with the support areas. Most of this requirements are included in ISO 17025:2005; that assurance the effective compliance of this standard.

  4. Energy thrift and improved performance achieved through novel railway brake discs

    A disc with radial vanes and circumferential pillars proves to be successful in operation and achieves energy efficiency improvements compared with those of traditional design. Cooling characteristics of this novel design are practically identical to the disc with tangential vanes but the equivalent aerodynamic (air pumping) losses are approximately 50% less. It is shown that these reductions in pumping losses can lead to substantial energy savings in train operations. When developing new designs and/or comparing different railway disc designs, the proposed disc cooling to aerodynamic efficiency ratio (ηv) was found to be a very useful parameter to assess. This 'efficiency ratio' - a ratio of convective power dissipation to aerodynamic power losses can help in achieving adequate balance of cooling efficiency and aerodynamic losses to suit particular application. The use of CFD is of enormous benefit in generating discs that fulfil these demanding requirements, with the spin rig being exceptionally useful for experimental work

    Liu, Feng; Jin, Zhongxiu; Zhu, Jun; Xu, Yafeng; Zhou, Li; Dai, Songyuan

    2016-06-01

    Achieving high surface coverage of the colloidal quantum dots (QDs) on TiO2 films has been challenging for quantum dot-sensitized solar cells (QDSCs). Herein, a general surface engineering approach was proposed to increase the loading of these QDs. It was found that S2- treatment/QD re-uptake process can significantly improve the attachment of the QDs on TiO2 films. Surface concentration of the QDs was improved by ∼60%, which in turn greatly enhances light absorption and decreases carrier recombination in QDSCs. Ensuing QDSCs with optimized QD loading exhibit a power conversion efficiency of 3.66%, 83% higher than those fabricated with standard procedures.

    Ardoy, D N; Fernández-Rodríguez, J M; Jiménez-Pavón, D; Castillo, R; Ruiz, J R; Ortega, F B

    2014-02-01

    To analyze the effects of an intervention focused on increasing the time and intensity of Physical Education (PE), on adolescents' cognitive performance and academic achievement. A 4-month group-randomized controlled trial was conducted in 67 adolescents from South-East Spain, 2007. Three classes were randomly allocated into control group (CG), experimental group 1 (EG1) and experimental group 2 (EG2). CG received usual PE (two sessions/week), EG1 received four PE sessions/week and EG2 received four PE sessions/week of high intensity. Cognitive performance (non-verbal and verbal ability, abstract reasoning, spatial ability, verbal reasoning and numerical ability) was assessed by the Spanish Overall and Factorial Intelligence Test, and academic achievement by school grades. All the cognitive performance variables, except verbal reasoning, increased more in EG2 than in CG (all P improved more than EG1, without differences between EG1 and CG. Increased PE can benefit cognitive performance and academic achievement. This study contributes to the current knowledge by suggesting that the intensity of PE sessions might play a role in the positive effect of physical activity on cognition and academic success. Future studies involving larger sample sizes should confirm or contrast these preliminary findings. PMID:23826633

  13. From Guide to Practice: Improving Your After School Science Program to Increase Student Academic Achievement

    Taylor, J.

    2013-12-01

    Numerous science organizations, such as NASA, offer educational outreach activities geared towards after school. For some programs, the primary goal is to grow students' love of science. For others, the programs are also intended to increase academic achievement. For those programs looking to support student learning in out-of-school time environments, aligning the program with learning during the classroom day can be a challenge. The Institute for Education Sciences, What Works Clearinghouse, put together a 'Practice Guide' for maximizing learning time beyond the regular school day. These practice guides provide concrete recommendations for educators supported by research. While this guide is not specific to any content or subject-area, the recommendations provided align very well with science education. After school science is often viewed as a fun, dynamic environment for students. Indeed, one of the recommendations to ensure time is structured according to students' needs is to provide relevant and interesting experiences. Given that our after school programs provide such creative environments for students, what other components are needed to promote increased academic achievement? The recommendations provided to academic achievement, include: 1. Align Instruction, 2. Maximize Attendance and Participation, 3. Adapt Instruction, 4. Provide Engaging Experiences, and 5. Evaluate Program. In this session we will examine these five recommendations presented in the Practice Guide, discuss how these strategies align with science programs, and examine what questions each program should address in order to provide experiences that lend themselves to maximizing instruction. Roadblocks and solutions for overcoming challenges in each of the five areas will be presented. Jessica Taylor will present this research based on her role as an author on the Practice Guide, 'Improving Academic Achievement in Out-of-School Time' and her experience working in various informal science

  17. Improvement in performance of DM plant, secondary systems for achieving chemistry performance indicator of KGS-3 and 4

    Kaiga Generating Station (KGS)-3 and 4 has two 220 MWe Pressurized Heavy Water Reactors. It uses Heavy water as moderator and coolant and DM (De-mineralized) water in secondary system for steam generation. Raw water for plant is taken from Kali River. Raw water is first treated in pretreatment plant and Dual media filter for turbidity removal. Chlorination is carried out for control of micro-organism. DM water is makeup to feed water which is the input to Steam Generator for production of steam for power generation. Continuous blow down through Boiler blow down (BBD) IX column is carried out to control Steam Generator (SG) chemistry. It was decided by Nuclear Power Corporation India Limited (NPCIL) management to calculate Chemistry Performance Indicator of KGS secondary system and it was found 2.6 which was much higher than Standard and best achievable value of 1.0. Detailed analysis was carried out and improvements required in DM plant, water treatment plant, BBD IX column, Steam Generator etc were identified and plan was made for improvement. Turbidity of filter water was brought below 2.0 NTU. Many changes were incorporated in DM plant. Regenerate concentration, regeneration levels and regeneration procedures were modified. Resin replacement frequencies were fixed and brine treatment of anion resin was started at regular interval. For DM water production two mixed resin columns in series were used in place of earlier one mixed resin column. By these modifications DM water Chloride, Sodium and Sulphate were brought <1.0 ppb from earlier 5-10 ppb. Regeneration procedure of BBD IX column were standardized. Service life of BBD IX column was fixed and was isolated from service before exhaustion. Design deficiencies of BBD IX column was rectified by applying innovative idea. Online sodium analyzer was installed in boiler blow down line. By implementing these improvements Chemistry Performance Indicator of both units were brought down to 1.0, which is standard and best

  18. Improving quality of sample entropy estimation for continuous distribution probability functions

    Miśkiewicz, Janusz

    2016-05-01

    Entropy is a one of the key parameters characterizing state of system in statistical physics. Although, the entropy is defined for systems described by discrete and continuous probability distribution function (PDF), in numerous applications the sample entropy is estimated by a histogram, which, in fact, denotes that the continuous PDF is represented by a set of probabilities. Such a procedure may lead to ambiguities and even misinterpretation of the results. Within this paper, two possible general algorithms based on continuous PDF estimation are discussed in the application to the Shannon and Tsallis entropies. It is shown that the proposed algorithms may improve entropy estimation, particularly in the case of small data sets.

  19. Comprehensive approach to improving maternal health and achieving MDG 5: report from the mountains of Lesotho.

    Hind Satti

    Full Text Available BACKGROUND: Although it is now widely recognized that reductions in maternal mortality and improvements in women's health cannot be achieved through simple, vertical strategies, few programs have provided successful models for how to integrate services into a comprehensive program for maternal health. We report our experience in rural Lesotho, where Partners In Health (PIH in partnership with the Ministry of Health and Social Welfare implemented a program that provides comprehensive care of pregnant women from the community to the clinic level. METHODS: Between May and July 2009, PIH trained 100 women, many of whom were former traditional birth attendants, to serve as clinic-affiliated maternal health workers. They received performance-based incentives for accompanying pregnant women during antenatal care (ANC visits and facility-based delivery. A nurse-midwife provided ANC and delivery care and supervised the maternal health workers. To overcome geographic barriers to delivering at the clinic, women who lived far from the clinic stayed at a maternal lying-in house prior to their expected delivery dates. We analyzed data routinely collected from delivery and ANC registers to compare service utilization before and after implementation of the program. RESULTS: After the establishment of the program, the average number first ANC visits increased from 20 to 31 per month. The clinic recorded 178 deliveries in the first year of the program and 216 in the second year, compared to 46 in the year preceding the program. During the first two years of the program, 49 women with complications were successfully transported to the district hospital, and no maternal deaths occurred among the women served by the program. CONCLUSIONS: Our results demonstrate that it is possible to achieve dramatic improvements in the utilization of maternal health services and facility-based delivery by strengthening human resource capacity, implementing active follow-up in the

  20. Expanding Continuous Quality Improvement Capacity in the Medical Intensive Care Unit: Prehealth Volunteers as a Solution.

    Priest, Kelsey C; Lobingier, Hannah; McCully, Nancy; Lombard, Jackie; Hansen, Mark; Uchiyama, Makoto; Hagg, Daniel S

    2016-01-01

    Health care delivery systems are challenged to support the increasing demands for improving patient safety, satisfaction, and outcomes. Limited resources and staffing are common barriers for making significant and sustained improvements. At Oregon Health & Science University, the medical intensive care unit (MICU) leadership team faced internal capacity limitations for conducting continuous quality improvement, specifically for the implementation and evaluation of the mobility portion of an evidence-based care bundle. The MICU team successfully addressed this capacity challenge using the person power of prehealth volunteers. In the first year of the project, 52 trained volunteers executed an evidence-based mobility intervention for 305 critically ill patients, conducting more than 200 000 exercise repetitions. The volunteers contributed to real-time evaluation of the project, with the collection of approximately 26 950 process measure data points. Prehealth volunteers are an untapped resource for effectively expanding internal continuous quality improvement capacity in the MICU and beyond. PMID:27031356

  1. Management of continual improvement for facilities and activities: A structured approach

    In recent years there has been an upward trend in the safety and operational performance of nuclear installations. Safe, efficient operation is their goal. Continual improvement of the processes of organizations has led to enhanced safety performance and efficiency benefits such as cost reductions and improved cycle times. Many organizations have experienced significant cost improvement largely by or through better financial management and a common drive to reduce costs brought on by commercial pressures. Without the use of a structured methodology to identify and implement improvements, changes to an organization to reduce costs through cutting staff and activities could eventually fail to produce the desired changes and even have a negative effect on safety and overall performance. The following fundamental principles are considered essential to the effective introduction of structured continual improvement: - Long term commitment from senior management throughout the entire organization; - The implementation in the organization of a process management approach such as that advocated by IAEA Safety Standards, ISO 9001, Malcolm Baldridge National Quality Award and European Foundation for Quality Management Business Excellence model; - The alignment of the processes with the objectives of the organization through the organization's business plan; - The utilization by Management of the process information as an input to managing the organization; - The employment of the information derived from the process performance to identify and prioritize the processes that require improvement; - The active participation of all staff of the organization to using its processes in order to contribute to continual process improvement (CPI). This publication defines a structured approach for continual improvement and focuses on the way an organization can improve its processes. It is recognized that there are many different approaches and methods available in the marketplace to

  6. The Stories Clinicians Tell: Achieving High Reliability and Improving Patient Safety.

    Cohen, Daniel L; Stewart, Kevin O

    2016-01-01

    The patient safety movement has been deeply affected by the stories patients have shared that have identified numerous opportunities for improvements in safety. These stories have identified system and/or human inefficiencies or dysfunctions, possibly even failures, often resulting in patient harm. Although patients' stories tell us much, less commonly heard are the stories of clinicians and how their personal observations regarding the environments they work in and the circumstances and pressures under which they work may degrade patient safety and lead to harm.If the health care industry is to function like a high-reliability industry, to improve its processes and achieve the outcomes that patients rightly deserve, then leaders and managers must seek and value input from those on the front lines-both clinicians and patients. Stories from clinicians provided in this article address themes that include incident identification, disclosure and transparency, just culture, the impact of clinical workload pressures, human factors liabilities, clinicians as secondary victims, the impact of disruptive and punitive behaviors, factors affecting professional morale, and personal failings.

  17. Continuous Cognitive Tasks Improve Postural Control Compared to Discrete Cognitive Tasks.

    Lajoie, Yves; Richer, Natalie; Jehu, Deborah A; Tran, Ylan

    2016-01-01

    Research suggests that postural control synergies are sensitive to cognitive manipulations; however, the impact of different types of cognitive tasks on postural control remains inconclusive. The authors examined the effect of discrete and continuous tasks on postural control. Sixteen healthy young adults (M age = 22.7 ± 2.2 years) stood with feet together on a force platform while performing randomly assigned discrete and continuous cognitive tasks. Results demonstrated marked improvements in the area of 95% confidence ellipse and the standard deviation of the center of pressure in the anterior-posterior and medial-lateral directions for continuous compared to discrete tasks. This reinforces the notion that continuous tasks are sufficient in providing less opportunity to consciously attend to postural control, thereby facilitating automatic postural control.

  18. Continuous improvement in dietetics education with a regional advisory board: a model that works.

    Martin, Rose L

    2003-08-01

    Continuous improvement has been a focus of business and health care for years. The Commission on Accreditation for Dietetics Education has also identified the need for continuous improvement in dietetics education programs and requires them to seek outside counsel to help accomplish it. Most dietetics education programs develop advisory boards to provide this outside counsel, but finding individuals to commit to an ongoing advisory board can be challenging. Dietetics internship directors from dietetics practicum programs throughout Arizona created the Arizona Dietetic Practicum Advisory Committee (AzDPAC), which uses suggestions from preceptors, interns, and committee members to generate ideas for improvement. Since the conception of AzDPAC both tangible and intangible outcomes have occurred. Tangible outcomes include better coordination among programs, development of a combined annual affiliate meeting, standardization of forms, creation of a combined "Clinical Bootcamp," development of a Web page describing all programs, and better networking among interns from different programs. In addition, AzDPAC improved cooperation and sharing of expertise and created an available group of peers for new directors. An advisory committee of regional program directors is a model that works in providing dietetics education programs with ongoing outside counsel and ideas for continuous improvement. PMID:12891153

  19. Independent assessment to continue improvement: Implementing statistical process control at the Hanford Site

    A Quality Assurance independent assessment has brought about continued improvement in the PUREX Plant surveillance program at the Department of Energy's Hanford Site. After the independent assessment, Quality Assurance personnel were closely involved in improving the surveillance program, specifically regarding storage tank monitoring. The independent assessment activities included reviewing procedures, analyzing surveillance data, conducting personnel interviews, and communicating with management. Process improvement efforts included: (1) designing data collection methods; (2) gaining concurrence between engineering and management, (3) revising procedures; and (4) interfacing with shift surveillance crews. Through this process, Statistical Process Control (SPC) was successfully implemented and surveillance management was improved. The independent assessment identified several deficiencies within the surveillance system. These deficiencies can be grouped into two areas: (1) data recording and analysis and (2) handling off-normal conditions. By using several independent assessment techniques, Quality Assurance was able to point out program weakness to senior management and present suggestions for improvements. SPC charting, as implemented by Quality Assurance, is an excellent tool for diagnosing the process, improving communication between the team members, and providing a scientific database for management decisions. In addition, the surveillance procedure was substantially revised. The goals of this revision were to (1) strengthen the role of surveillance management, engineering and operators and (2) emphasize the importance of teamwork for each individual who performs a task. In this instance we believe that the value independent assessment adds to the system is the continuous improvement activities that follow the independent assessment. Excellence in teamwork between the independent assessment organization and the auditee is the key to continuing improvement

  20. Development of a handoff continuity score to improve pediatric ICU physician schedule design for enhanced physician and patient continuity

    Smalley, Hannah K; Keskinocak, Pinar; Vats, Atul

    2011-01-01

    Introduction Few studies investigate the benefits of familiarity or continuity during physician-to-physician handoff of inpatients. Factors such as how recently physicians (MDs) have worked and successive days caring for patients increase continuity, and thus could lead to enhanced handoff efficiency. Evaluating the efficacy of MD scheduling to enhance continuity is currently subjective. Methods An MD group consisting of 9 attending physicians and 7 fellows redesigned its pediatric intensive ...

  1. Improving Science Achievement and Attitudes of Students With and Without Learning Disabilities

    Sanders-White, Pamela

    The primary purpose of this study was to investigate the effect of structured note-taking compared to traditional note-taking on the acquisition of scientific knowledge for students with and without learning disabilities (LD) and students with reading difficulties (RD). An additional purpose was to examine whether the two note-taking methods affected students' attitudes toward science. The sample population consisted of 203 fifth grade students across four public schools in the southern area of the United States. A standardized instrument aligned to Florida's science standards was used to measure the acquisition of scientific knowledge and the Test of Science-Related Attitudes (TOSRA) was used to measure seven distinct science-related attitudes. For meaningful analyses, students with LD and students with RD were collapsed to form a single group due to the small numbers of participants in each of the subgroups; the collapsed group was referred to as "low achievers." A three-way repeated measures ANOVA was conducted to determine the effects of the pretest-posttest Science Interim assessment by group, type of student, and gender. The pretest-posttest Science Interim assessment scores were the within-group factor, while group, type of student, and gender were the between-groups factors. Results revealed that there was a significant interaction between the pretest-posttest Science Interim assessment and group, F(1, 191) = 9.320, p = .003, indicating that scientific knowledge scores increased for the experimental group, but decreased for the control group. Results also indicated that there was a significant three-way interaction between the pretest-posttest Science Interim assessment, group, and gender, F(1, 191) = 5.197, p = .024, showing that all participants in the experimental group improved their scores; while in the control group, female scores decreased and male scores increased. Participants in the experimental and control groups did not show improved attitudes

  2. How Visual Management for Continuous Improvement Might Guide and Affect Hospital Staff: A Case Study.

    Ulhassan, Waqar; von Thiele Schwarz, Ulrica; Westerlund, Hugo; Sandahl, Christer; Thor, Johan

    2015-01-01

    Visual management (VM) tools such as whiteboards, often employed in Lean thinking applications, are intended to be helpful in improving work processes in different industries including health care. It remains unclear, however, how VM is actually applied in health care Lean interventions and how it might influence the clinical staff. We therefore examined how Lean-inspired VM using whiteboards for continuous improvement efforts related to the hospital staff's work and collaboration. Within a case study design, we combined semistructured interviews, nonparticipant observations, and photography on 2 cardiology wards. The fate of VM differed between the 2 wards; in one, it was well received by the staff and enhanced continuous improvement efforts, whereas in the other ward, it was not perceived to fit in the work flow or to make enough sense in order to be sustained. Visual management may enable the staff and managers to allow communication across time and facilitate teamwork by enabling the inclusion of team members who are not present simultaneously; however, its adoption and value seem contingent on finding a good fit with the local context. A combination of continuous improvement and VM may be helpful in keeping the staff engaged in the change process in the long run. PMID:26426324

  4. The Continued Evaluation of Voucher Impact on the Achievement of Elementary Students in a Majority African American Public School District

    Metcalf, Kim K.; Boone, William J.; Legan, Natalie A.; Paul, Kelli M.

    Vouchers for students in urban school districts may promote the increased participation of underrepresented groups in the fields of science and engineering in at least two ways: (a) by optimizing the achievement of students who use vouchers and (b) by expanding the scope of educational and curricular options available to students. Presently, nearly 5,000 children in Cleveland, Ohio, attend private schools with publicly funded vouchers. This study presents the results of evaluating the achievement of a cohort of these students from the fall of first grade to the spring of fourth grade. For public school students, first grade seems to be a time during which they catch up with peers who attend private schools with vouchers. The analysis of data using adjusted measures suggests no differences in achievement from first grade to fourth grade with respect to achievement in many content areas. The use of unadjusted measures suggests possible differences with respect to fourth grade reading (with voucher students performing at a statistically higher level than their peers). The present data set neither clearly supports nor refutes the use of vouchers.

  5. Harnessing the genetics of the modern dairy cow to continue improvements in feed efficiency.

    VandeHaar, M J; Armentano, L E; Weigel, K; Spurlock, D M; Tempelman, R J; Veerkamp, R

    2016-06-01

    Feed efficiency, as defined by the fraction of feed energy or dry matter captured in products, has more than doubled for the US dairy industry in the past 100 yr. This increased feed efficiency was the result of increased milk production per cow achieved through genetic selection, nutrition, and management with the desired goal being greater profitability. With increased milk production per cow, more feed is consumed per cow, but a greater portion of the feed is partitioned toward milk instead of maintenance and body growth. This dilution of maintenance has been the overwhelming driver of enhanced feed efficiency in the past, but its effect diminishes with each successive increment in production relative to body size and therefore will be less important in the future. Instead, we must also focus on new ways to enhance digestive and metabolic efficiency. One way to examine variation in efficiency among animals is residual feed intake (RFI), a measure of efficiency that is independent of the dilution of maintenance. Cows that convert feed gross energy to net energy more efficiently or have lower maintenance requirements than expected based on body weight use less feed than expected and thus have negative RFI. Cows with low RFI likely digest and metabolize nutrients more efficiently and should have overall greater efficiency and profitability if they are also healthy, fertile, and produce at a high multiple of maintenance. Genomic technologies will help to identify these animals for selection programs. Nutrition and management also will continue to play a major role in farm-level feed efficiency. Management practices such as grouping and total mixed ration feeding have improved rumen function and therefore efficiency, but they have also decreased our attention on individual cow needs. Nutritional grouping is key to helping each cow reach its genetic potential. Perhaps new computer-driven technologies, combined with genomics, will enable us to optimize management for

  7. Successful treatment of Depot Medroxyprogesterone acetate-related vaginal bleeding improves continuation rates in Adolescents

    Kristin M. Rager

    2006-01-01

    Full Text Available High discontinuation rates for depot medroxyprogesterone acetate (DMPA in adolescents may contribute to the number of unintended pregnancies. Many cite vaginal bleeding as a reason for discontinuing DMPA use. In this study, we attempted to determine if treating DMPA-associated vaginal bleeding with monophasic oral contraceptive pills (OCP raised continuation rates. A total of 131 patients who reported vaginal bleeding while on DMPA were included in this study and 83 were treated with monophasic OCP. Of those who received OCP, 38.7% reported that vaginal bleeding stopped completely, 51.8% reported that vaginal bleeding stopped temporarily, and 6.0% reported no change. Overall, 94% of enrolled patients who received OCP as a treatment for DMPA-associated vaginal bleeding continued DMPA use. Our findings indicate that vaginal bleeding due to DMPA can be successfully treated, leading to improvement in continuation rates.

  12. Air quality continued to improve in 2014, but progress are still needed

    The improvement in air quality that began some years ago continued. Average concentrations of pollutants decreased and exceedance of thresholds for protection of health was observed in fewer areas. Progress was, notably, the result of efforts made to reduce emissions, something made more difficult by the number and variety of sources of pollution. These improvements were, however, fragile as they were partially dependent on weather conditions. 2014 was, thus, marked by an important episode of particulate pollution. In addition, the progress made was not sufficient to bring France into full compliance with European standards, as was also the case for other European countries. (author)

  13. An Experimental Investigation to Facilitate an Improvement in the Design of an Electromagnetic Continuous Casting Mould

    Lintao Zhang

    2016-04-01

    Full Text Available An electromagnetic continuous casting mould designed is proposed with a non-uniform slit distribution structure. This design has aimed to reduce the number of slits so that the mould’s strength is enhanced, whilst maintaining a similar metallurgy effect. In this paper, the metallurgy effect for the designed mould is investigated through the magnetic field distribution along the casting direction, the uniformity feature in the vicinity of the meniscus region, the temperature variation of the molten alloy pool and the mould wall. The results show that the designed mould achieved a similar effect as compared to the original mould; however, the configuration is simplified. This research highlights the topic of mould structure optimization, which would enable the Electromagnetic continuous casting (EMCC technique to be utilized with greater ease by industry.

  4. Design improvements and R and D achievements for VV and In-vessel components towards ITER construction

    There have been several detailed vacuum vessel (VV) design improvements, such as elimination of the inboard triangular support, separate interspace between inner and outer shells for independent leak detection of field joints and revised VV support system to gain a more comfortable margin in the structural performance. The blanket design has been updated; an inter-modular key instead of two prismatic keys and a co-axial inlet-outlet cooling connection instead of two parallel pipes. One of the most important achievements in the VV R and D has been demonstration of the necessary assembly tolerances. Further development of cutting, welding and non destructive tests (NDT) for the VV has been continued, and thermal and hydraulic tests have been performed to simulate the VV cooling conditions. With regard to the R and D for the FW/blanket and divertor, full-scale prototypical mock-ups of the FW panel, the blanket shield block and the divertor components have been successfully fabricated. These results make us confident in the validity of our design and give us possibilities of alternate fabrication methods. (author)

    Carbon fibres and ultra-high-molecular-weight polyethylene (UHMWPE) fibres were continuously treated by a dielectric barrier discharge plasma at atmospheric pressure for adhesion improvement with epoxy resins. The plasma treatment improved wettability, increased the oxygen containing polar functional groups at the surface, and subsequently improved adhesion to the epoxy and fracture resistance of epoxy composites. Hansen solubility parameters (HSP), quantitatively describing physical interactions among molecules, were measured for the UHMWPE fibre surfaces. The result identifies two distinct types of surfaces in both the plasma treated and the untreated fibres. One type is typical of polyethylene polymers while the other is characteristic of the oxygenated surface at much higher values of HSP. (Author)

  7. Continuous improvement process and waste reduction through a QFD tool: the case of a metallurgic plant

    Leoni Pentiado Godoy

    2013-05-01

    Full Text Available This paper proposes the use of QFD for the continuous improvement of production processes and waste reduction actions. To collect the information we used the simple observation and questionnaire with closed questions applied to employees, representing 88.75% of the population that works in the production processes of an industry of metal-mechanic sector, located inRio Grandedo Sul. QFD is an effective method of quality planning, because it provides a diagnosis that underpins the definition of improvement actions aimed at combating waste. Actions were set providing improved communication between the sectors, enabling the delivery of products with specifications that meet customer requirements, on time and the right amounts, at a minimum cost and satisfaction of those involved with the company. The implementation of these actions reduces waste, minimizes the extra work, maximizes effective labor and increases profitability.

  9. Improvements of PKU PMECRIS for continuous hundred hours CW proton beam operation

    In order to improve the source stability, a long term continuous wave (CW) proton beam experiment has been carried out with Peking University compact permanent magnet 2.45 GHz ECR ion source (PKU PMECRIS). Before such an experiment a lot of improvements and modifications were completed on the source body, the Faraday cup and the PKU ion source test bench. At the beginning of 2015, a continuous operation of PKU PMECRIS for 306 h with more than 50 mA CW beam was carried out after success of many short term tests. No plasma generator failure or high voltage breakdown was observed during that running period and the proton source reliability is near 100%. Total beam availability, which is defined as 35-keV beam-on time divided by elapsed time, was higher than 99% [S. X. Peng et al., Chin. Phys. B 24(7), 075203 (2015)]. A re-inspection was performed after another additional 100 h operation (counting time) and no obvious sign of component failure was observed. Counting the previous source testing time together, this PMECRs longevity is now demonstrated to be greater than 460 h. This paper is mainly concentrated on the improvements for this long term experiment

  13. Good performance in Japan is proof of continuing safety and reliability improvement practice

    Nuclear power is a vital energy supply source for both security and economy for such countries as Japan whose sources of energy are dependent on imported materials. This is the very reason why Japan gives her national priority to the improvement of nuclear power safety and reliability. As of the end of 1986, total nuclear power capacity owned and operated by private utility companies in Japan amounted to 24521 MW with 32 units sharing -- 19% of the total generating capacity. Moreover, during 1986 these units scored a remarkably high capacity factor of 76.2% and shared almost 28% of the nationwide electric power production, thereby contributing to a considerable saving of imported sources of energy. This outstanding record has been achieved by the parties concerned who dedicated themselves to furthering nuclear plant safety and reliability improvement. In this connection, this paper summarizes those key factors contributing to the good nuclear power plant performance of the Kansai Electric Power Company

  14. Continuous Improvement and the Safety Case for the Waste Isolation Pilot Plant Geologic Repository - 13467

    The Waste Isolation Pilot Plant (WIPP) is a geologic repository 2150 feet (650 m) below the surface of the Chihuahuan desert near Carlsbad, New Mexico. WIPP permanently disposes of transuranic waste from national defense programs. Every five years, the U.S. Department of Energy (DOE) submits an application to the U.S. Environmental Protection Agency (EPA) to request regulatory-compliance re-certification of the facility for another five years. Every ten years, DOE submits an application to the New Mexico Environment Department (NMED) for the renewal of its hazardous waste disposal permit. The content of the applications made by DOE to the EPA for re-certification, and to the NMED for permit-renewal, reflect any optimization changes made to the facility, with regulatory concurrence if warranted by the nature of the change. DOE points to such changes as evidence for its having taken seriously its 'continuous improvement' operations and management philosophy. Another opportunity for continuous improvement is to look at any delta that may exist between the re-certification and re-permitting cases for system safety and the consensus advice on the nature and content of a safety case as being developed and published by the Nuclear Energy Agency's Integration Group for the Safety Case (IGSC) expert group. DOE at WIPP, with the aid of its Science Advisor and teammate, Sandia National Laboratories, is in the process of discerning what can be done, in a reasonably paced and cost-conscious manner, to continually improve the case for repository safety that is being made to the two primary regulators on a recurring basis. This paper will discuss some aspects of that delta and potential paths forward to addressing them. (authors)

  15. Environmental assessment, continual improvement and adaptive management within the AREVA sustainable development framework

    COGEMA Resources Inc. (which is part of the AREVA Group) is a Canadian company with its head office in Saskatoon, Saskatchewan. It owns and operates mining and milling facilities in northern Saskatchewan, which produce uranium concentrate. The McClean Lake Operation commenced production in 1999 and its environmental management system represents an integrated approach to environmental assessment, continual improvement and adaptive management based on operational results. In Canada, sustainable development is promoted through the application of the Canadian Environmental Assessment Act (CEAA). Environmental Assessment (EA) is a planning tool, which incorporates environmental considerations before irrevocable decisions are taken. The basic tenet of the Act is the determination of whether the potential environmental effects of a project are adverse, significant and likely, taking into consideration mitigation measures. Thus, project planning and design entails an iterative process that incorporates mitigation measures to minimize potentially significant adverse effects. As part of the EA process conservative approaches are taken to predict potential effects. Several important elements are generated through the EA process including: a set of environmental effects predictions, a compliance and environmental effects monitoring program, a follow-up program to address uncertainties in the prediction of environmental effects, and the identification of contingency measures that could be implemented should non-conservative assumptions be identified in the original assessment framework. The challenge is to integrate each of these elements into the environmental management framework of the operating facility and develop an iterative mechanism to evaluate operational performance relative to what was originally predicted. In Saskatchewan, a requirement of operational licenses is the periodic evaluation of the 'Status of the Environment' surrounding operational facilities. These

    2003-01-01

    The fidelity of teleportation of continuous quantum variables can be improved by tuning the local displace-ment gain. We investigate the optimization of the fidelity for the teleportation of Schrodinger cat states,and of coherent states. It is found that the gain corresponding to the maximum fidelity is not equal to onefor the two input states in the case of the small squeezing degree of the entanglement resource, while unitydisplacement gain is the best choice for teleporting arbitrary quantum states in the case of large squeezing.

The experts in nursing fields in China should learn the matured experience from abroad to open up the features and superiorities of Chinese interventional nursing. Therefore, the nursing workers in China should continually to make summing-up, exert oneself to deepen the related researches and effectively improve the interventional nursing level. (authors)

  18. Method of Improving the Navigation Accuracy of SINS by Continuous Rotation

    YANG Yong; MIAO Ling-juan; SHEN Jun

    2005-01-01

    A method of improving the navigation accuracy of strapdown inertial navigation system (SINS) is studied. The particular technique discussed involves the continuous rotation of gyros and accelerometers cluster about the vertical axis of the vehicle. Then the errors of these sensors will have periodic variation corresponding to components along the body frame. Under this condition, the modulated sensor errors produce reduced system errors. Theoretical analysis based on a new coordinate system defined as sensing frame and test results are presented, and they indicate the method attenuates the navigation errors brought by the gyros' random constant drift and the accelerometer's bias and their white noise compared to the conventional method.

  19. On improving the convergence rate of linear continuous-time systems subject to asymmetrically constrained control

    A. Baddou

    2006-01-01

    Full Text Available This paper solves the problem of controlling linear continuous-time systems subject to control signals constrained in magnitude (maybe asymmetrically. A controller design methodology is proposed, based on using an asymmetric Lyapunov function, that avoids the discontinuities in the control vector components resulting from the application of a piecewise linear control law previously proposed. The proposed method gives improved speed of convergence without discontinuities of the control vector components, respecting always the imposed asymmetric constraints. An example illustrates the approach.

    We show that the maximum transmission distance of continuous-variable quantum key distribution in presence of a Gaussian noisy lossy channel can be arbitrarily increased using a heralded noiseless linear amplifier. We explicitly consider a protocol using amplitude and phase modulated coherent states with reverse reconciliation. Assuming that the secret key rate drops to zero for a line transmittance T{sub lim}, we find that a noiseless amplifier with amplitude gain g can improve this value to T{sub lim}/g{sup 2}, corresponding to an increase in distance proportional to log g. We also show that the tolerance against noise is increased.

  1. Improvement of two-way continuous-variable quantum key distribution using optical amplifiers

    The imperfections of a receiver's detector affect the performance of two-way continuous-variable (CV) quantum key distribution (QKD) protocols and are difficult to adjust in practical situations. We propose a method to improve the performance of two-way CV-QKD by adding a parameter-adjustable optical amplifier at the receiver. A security analysis is derived against a two-mode collective entangling cloner attack. Our simulations show that the proposed method can improve the performance of protocols as long as the inherent noise of the amplifier is lower than a critical value, defined as the tolerable amplifier noise. Furthermore, the optimal performance can approach the scenario where a perfect detector is used. (paper)

  2. Valuation of environmental improvements in continuous time with mortality and morbidity effects

    We present a model for valuing environmental improvements in continuous time, for individuals that can be either healthy (H) or ill (I), with constant transition between the states and constant mortality rates in each state, when environmental quality affects welfare, mortality and morbidity. The values in states H and I, VSL(H) and VSL(I), are derived from two Bellman dynamic programming equations. The individual's valuation of (small) instantaneous environmental changes, and of permanent environmental changes ('environmental investments'), are shown to depend on both VSL(H) and VSL(I), for each of the states H and I. We show that VSL(I) may exceed VSL(H), and the value of environmental improvements in the ill state may exceed those in the healthy state, in particular for short-lasting illness and when the marginal value of consumption is lower in state I than in state H.

  3. Improved Achievable Rates for Regularized Tomlinson-Harashima Precoding in Multiuser MIMO Downlink

    Hui, Bing; Chang, KyungHi

    2011-01-01

    Tomlinson-Harashima precoding (THP) is considered as a prominent precoding scheme due to its capability to efficiently cancel out the known interference at the transmitter side. Therefore, the information rates achieved by THP are superior to those achieved by conventional linear precoding schemes. In this paper, a new lower bound on the achievable information rate for the regularized THP scheme under additive white Gaussian noise (AWGN) channel with multiuser interference is derived. Analytical results show that the lower bound derived in this paper is tighter than the original lower bound particularly for a low SNR range, while all lower bounds converge to 0.5xlog2(6SNR/{\\pi}e) as SNR approaches infinity.

  4. Continuing Improvement in the Planetary Ephemeris with VLBA Observations of Cassini

    Jones, Dayton L.; Folkner, William M.; Jacobson, Robert A.; Jacobs, Christopher S.; Romney, Jonathan D.; Dhawan, Vivek; Fomalont, Edward B.

    2016-06-01

    During the past decade a continuing series of measurements of the barycentric position of the Saturn system in the inertial International Celestial Reference Frame (ICRF) has led to a significant improvement in our knowledge of Saturn's orbit. This in turn has improved the current accuracy and time range of the solar system ephemeris produced and maintained by the Jet Propulsion Laboratory. Our observing technique involves high-precision astrometry of the radio signal from Cassini with the NRAO Very Long Baseline Array, combined with solutions for the orbital motion of Cassini about the Saturn barycenter from Doppler tracking by the Deep Space Network. Our VLBA astrometry is done in a phase-referencing mode, providing nrad-level relative positions between Cassini and angularly nearby extragalactic radio sources. The positions of those reference radio sources are tied to the ICRF through dedicated VLBI observations by several groups around the world. We will present recent results from our astrometric observations of Cassini through early 2016. This program will continue until the end of the Cassini mission in 2017, although future improvement in Saturn's orbit will be more incremental because we have already covered more that a quarter of Saturn's orbital period. The Juno mission to Jupiter, which will orbit Jupiter for about 1.5 years starting in July 2016, will provide an excellent opportunity for us to apply the same VLBA astrometry technique to improve the orbit of Jupiter by a factor of several. The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

  5. Safety implications of standardized continuous quality improvement programs in community pharmacy.

    Boyle, Todd A; Ho, Certina; Mackinnon, Neil J; Mahaffey, Thomas; Taylor, Jeffrey M

    2013-06-01

    Standardized continuous quality improvement (CQI) programs combine Web-based technologies and standardized improvement processes, tools, and expectations to enable quality-related events (QREs) occurring in individual pharmacies to be shared with pharmacies in other jurisdictions. Because standardized CQI programs are still new to community pharmacy, little is known about how they impact medication safety. This research identifies key aspects of medication safety that change as a result of implementing a standardized CQI program. Fifty-three community pharmacies in Nova Scotia, Canada, adopted the SafetyNET-Rx standardized CQI program in April 2010. The Institute for Safe Medication Practices (ISMP) Canada's Medication Safety Self-Assessment (MSSA) survey was administered to these pharmacies before and 1 year into their use of the SafetyNET-Rx program. The nonparametric Wilcoxon signed-rank test was used to explore where changes in patient safety occurred as a result of SafetyNETRx use. Significant improvements occurred with quality processes and risk management, staff competence, and education, and communication of drug orders and other information. Patient education, environmental factors, and the use of devices did not show statistically significant changes. As CQI programs are designed to share learning from QREs, it is reassuring to see that the largest improvements are related to quality processes, risk management, staff competence, and education.

  8. Continuous emission monitoring systems at power plants in China: Improving SO2 emission measurement

    The Chinese Government recently mandated the installation of continuous emission monitoring systems (CEMS) at state-controlled key polluting facilities in order to provide direct, real-time, continuous measurements of sulfur dioxide (SO2) emissions. By 2010, most coal-fired power plants in China have installed and are operating SO2 CEMS. As China's Central Government strengthens the SO2 control program and implements new nitrogen oxides (NOX) and carbon dioxide (CO2) control programs, the quality of and confidence in CEMS data will become more important. This study utilizes field surveys and existing literature on Chinese CEMS to analyze their operation and management. Our study found that the Chinese government has issued a set of regulations and technical guidance documents to standardize CEMS operation, management, and supervision, and to improve the quality of CEMS data. Many power plants have followed key parts of the national CEMS rules and guidance and are periodically inspected by local environmental authorities. This study suggests several options for addressing some of the gaps and problems with the CEMS operation and supervision and thus enhancing China's CEMS program. - Highlights: → Nearly all coal power plants in China have SO2 CEMS providing direct, real-time, continuous measurements of emissions. → Government and industry have made significant progress toward a comprehensive measurement system. → We found that problems remain and CEMS operation and supervision is inconsistent. → Data from power plant CEMS often undergo limited quality assurance and analysis. → We propose some options for enhancing the CEMS network.

  1. Strategic planning as a focus for continuous improvement. A case study

    Oneill, John W.; Gordon-Winkler, Lyn

    1992-01-01

    What do most of the successful people and organizations in our world have in common? Instead of worrying about the future, they work to create it. They have a plan, or a vision of what they want to accomplish and they focus their efforts on success. Strategic planning has been described as a disciplined, ongoing process to produce fundamental decisions and actions that shape what an organization is, what it does, and how it will respond to a changing environment. This case study discussion will evaluate the relationship between strategic planning and Total Quality Management (TQM), or continuous improvement, through the experience of the NASA Johnson Space Center in developing a strategy for the future. That experience clearly illustrates the value of strategic planning in setting the framework and establishing the overall thrust of continuous improvement initiatives. Equally significant, the fundamentals of a quality culture such as strong customer and supplier partnerships, participative involvement, open communications, and ownership were essential in overcoming the challenges inherent in the planning process. A reinforced management commitment to the quality culture was a clear, long-term benefit.

Johnson Space Center in Houston, Texas conducts development and qualification tests to fulfill Energy System Division responsibilities relevant to ASA programs and projects. EST A has historically called upon a variety of fluid, mechanical, electrical, environmental, and data system capabilities spread amongst five full-service facilities to test human and human supported spacecraft in the areas of propulsion systems, fluid systems, pyrotechnics, power generation, and power distribution and control systems. Improvements at ESTA are being made in full earnest of offering NASA project offices an option to choose a thorough test regime that is balanced with cost and schedule constraints. In order to continue testing of enabling power-related technologies utilized by the Energy System Division, an especially proactive effort has been made to increase the cost effectiveness and schedule responsiveness for battery testing. This paper describes the continuous improvement in battery testing at the Energy Systems Test Area being made through consolidation, streamlining, and standardization.

  3. Waste Minimization Improvements Achieved Through Six Sigma Analysis Result In Significant Cost Savings

    Improved waste minimization practices at the Department of Energy's (DOE) Idaho National Engineering and Environmental Laboratory (INEEL) are leading to a 15% reduction in the generation of hazardous and radioactive waste. Bechtel, BWXT Idaho, LLC (BBWI), the prime management and operations contractor at the INEEL, applied the Six Sigma improvement process to the INEEL Waste Minimization Program to review existing processes and define opportunities for improvement. Our Six Sigma analysis team: composed of an executive champion, process owner, a black belt and yellow belt, and technical and business team members used this statistical based process approach to analyze work processes and produced ten recommendations for improvement. Recommendations ranged from waste generator financial accountability for newly generated waste to enhanced employee recognition programs for waste minimization efforts. These improvements have now been implemented to reduce waste generation rates and are producing positive results

  5. Continuous heating of an air-source heat pump during defrosting and improvement of energy efficiency

    Highlights: • The newly designed dual hot gas spray defrosting method was examined. • Uninterrupted heating of an air source heat pump during defrosting. • We compared newly designed dual hot gas and traditional reverse cycle defrost. • Total energy efficiency was increased by 8% compared to traditional method. - Abstract: During winter operation, an air-source heat pump extracts heat from the cold outside air and releases the heat into the living space. At certain outside air conditions, when it operates in heating mode, frost can form on the air-cooled heat exchanger, decreasing the heating performance. Conventionally, reverse-cycle defrosting (RCD) has been the common method of frost removal. But this method requires the interruption of heating during defrosting, as well as a period of time to reheat the cooled pipes of the indoor units after defrosting. In this study, a new technology called continuous heating was developed, which utilize only a hot gas bypass valve to remove the frost from the outdoor heat exchanger and thus enabling the supply of hot air to indoors without any interruption. For this, a new high temperature and low pressure gas bypass method was designed, which is differentiated from the common high pressure hot gas bypass methods by its use of low pressure. Various refrigerant mass flow distributions were examined, and the most effective defrosting mass flow was 50% in this case. Heating capacity was increased by 17% because of continuous heating, and the cumulated energy efficiency was increased by 8% compared to the traditional reverse cycle defrosting over 4 h including two defrost operations. Also, cumulated energy efficiency was increased by 27% compared to electronic heaters that supply the same heating capacity during defrosting. By this new technology, it has been proved that continuous heating and energy savings could be achieved without adopting expensive technologies

    Full Text Available Language education curricula and programs worldwide have begun emphasizing foreign language instruction for learners as young as 5-6 years, particularly in English. Yet, while studies have argued for the benefits of early language instruction, the results of this trend in terms of actual achievement are not clear. For this reason, the researchers designed this study to illustrate the connection between age of onset of English as a foreign language (EFL instruction and learner achievement, examining international language curricula from countries where English is taught as a foreign language beginning at the pre-primary and primary level alongside the corresponding scores on the Test of English as a Foreign Language (TOEFL. The findings indicate that, although early onset of EFL instruction may be beneficial in many respects, it is not, in itself, a guarantee of success, and other elements, such as class size, number of hours dedicated to English instruction, and teacher qualifications, must also be considered.

    An evaluation of a single continuing education (CE) program was conducted by the presenter to assess impact of the offering and gather information for course improvement. The purpose of this evaluation was to document if and to what extent the learners attained the program's objectives and also to systematically examine the program to see how it might be improved. The third purpose was to document if participants' interest was stimulated by the program and if they actually used the information in clinical practice or at least found it helpful. Fifty-five nurses participated in completing a pretest and posttest, reactionnaire at the conclusion of the program and follow-up questionnaire. Participants made significantly (p less than .05) better scores on the posttests as compared to the pretest. On the evaluation form, 98% of the nurses responded that they had learned new facts, and 75% indicated that information was moderately new. In addition, a slight majority (58%) responded that they changed their beliefs about assertiveness. Of returned follow-up questionnaires, 95% told others about the program, and 59% read articles. All nurses indicated they had found the information useful, and 87% had actually used the information in clinical practice. This study documents a method for CE administrators and educators to evaluate the impact of CE and provide information for course improvement. The evaluation supports the program's worth. Participants benefited in terms of knowledge and interest. In addition, program strengths/weaknesses were identified. PMID:6325622

  19. The Nearly Continuous Improvement of Discharge Characteristics and Edge Stability with Increasing Lithium Coatings in NSTX

    Full text: The understanding of regimes with: 1. High pressure at the top of the H-mode pedestal. 2. Devoid of large ELMs is important for scenario optimization of ITER and future devices. Lithium wall coatings have been shown to both improve energy confinement and eliminate ELMs in NSTX. Here, we present analysis of variable pre-discharge lithium evaporation from multiple experiments, for more insight into the pedestal expansion and ELM suppression physics. First, a nearly continuous improvement of a number of discharge characteristics, e.g., reduced recycling, ELM frequency, and edge electron transport, with increasing pre-discharge lithium evaporation has been identified. These correlations ran contrary to initial expectations that the beneficial effects would saturate at much lower evaporation amounts than used in experiments. Profile and stability analysis clarified the mechanism responsible for ELM avoidance and the role of lithium: lithium coatings reduce recycling and core fueling; thus the density and its gradient near the separatrix are reduced. The temperature gradient near the separatrix is unaffected; hence the pressure gradient and bootstrap current near the separatrix are reduced, leading to stabilization of kink/peeling modes thought to be responsible for the NSTX ELMs. Thus, the enhanced edge stability with lithium coatings is correlated with the reduction of the pressure and its gradient near the separatrix. The key ingredient for ELM avoidance is control of the particle channel independent of the thermal channel at the edge: the density profile is continuously manipulated via the amount of lithium evaporation and resulting recycling control, leading to reduced neutral fueling. The surprising and beneficial facet of the NSTX data, however, is the continued growth of the edge transport barrier width in these circumstances, leading to 100 % higher plasma pressure at the approximate top of the ne profile barrier with high pre-discharge evaporation

  20. A Gaussian-like immersed-boundary kernel with three continuous derivatives and improved translational invariance

    Bao, Yuanxun; Kaye, Jason; Peskin, Charles S.

    2016-07-01

    The immersed boundary (IB) method is a general mathematical framework for studying problems involving fluid-structure interactions in which an elastic structure is immersed in a viscous incompressible fluid. In the IB formulation, the fluid described by Eulerian variables is coupled with the immersed structure described by Lagrangian variables via the use of the Dirac delta function. From a numerical standpoint, the Lagrangian force spreading and the Eulerian velocity interpolation are carried out by a regularized, compactly supported discrete delta function, which is assumed to be a tensor product of a single-variable immersed-boundary kernel. IB kernels are derived from a set of postulates designed to achieve approximate grid translational invariance, interpolation accuracy and computational efficiency. In this note, we present a new 6-point immersed-boundary kernel that is C3 and yields a substantially improved translational invariance compared to other common IB kernels.

    Full Text Available A key postulate of traditional theories of motor skill learning (e.g., Fitts and Posner, 1967; Shiffrin and Schneider, 1977 is that expert performance is largely automatic in nature and tends to deteriorate when the performer ‘reinvests’ in, or attempts to exert conscious control over, proceduralized movements (Masters and Maxwell, 2008.

  4. Achieving k-anonymity Using Improved Greedy Heuristics for Very Large Relational Databases

    Korra Sathya Babu

    2013-04-01

    Full Text Available Advances in data storage, data collection and inference techniques have enabled the creation of huge databases of personal information. Dissemination of information from such databases - even if formally anonymised, creates a serious threat to individual privacy through statistical disclosure. One of the key methods developed to limit statistical disclosure risk is k-anonymity. Several methods have been proposed to enforce k-anonymity notably Samarati's algorithm and Sweeney's Datafly, which both adhere to full domain generalisation. Such methods require a trade off between computing time and information loss. This paper describes an improved greedy heuristic for enforcing k-anonymity with full domain generalisation. The improved greedy algorithm was compared with the original methods. Metrics like information loss, computing time and level of generalisation were deployed for comparison. Results show that the improved greedy algorithm maintains a better balance between computing time and information loss.

    Full Text Available The importance of interaction between Operations Management (OM and Human Behavior has been recently re-addressed. This paper introduced the Reasoned Action Theory suggested by Froehle and Roth (2004 to analyze Operational Capabilities exploring the suitability of this model in the context of OM. It also seeks to discuss the behavioral aspects of operational capabilities from the perspective of organizational routines. This theory was operationalized using Fishbein and Ajzen (F/A behavioral model and a multi-case strategy was employed to analyze the Continuous Improvement (CI capability. The results posit that the model explains partially the CI behavior in an operational context and some contingency variables might influence the general relationsamong the variables involved in the F/A model. Thus intention might not be the determinant variable of behavior in this context.

  12. The new health-care quality: value, outcomes, and continuous improvement.

    O'Connor, S J; Lanning, J A

    1991-01-01

    No longer convinced that their viewpoint on quality is the only one, different stakeholders in the health-care arena are sharing perspectives to piece together the quality picture. Although still preoccupied with the cost of health care, purchasers are concerned about value--efficiency, appropriateness, and effectiveness--as well as price. Faced with evidence of medically unnecessary procedures and unexamined medical theory, practitioners are searching for appropriateness guidelines, useful outcome measures, and methods to elicit informed patient preferences about elective surgeries. Underlying this search for reliable indicators of quality--now expanded to include patient satisfaction--is a new interest in the Japanese notion of "Kaizen" or continuous quality improvement. The end product of this ferment may determine whether good medicine drives out the bad--or vice versa. PMID:10118887

  19. An Improved Real-Coded Population-Based Extremal Optimization Method for Continuous Unconstrained Optimization Problems

    Guo-Qiang Zeng

    2014-01-01

    Full Text Available As a novel evolutionary optimization method, extremal optimization (EO has been successfully applied to a variety of combinatorial optimization problems. However, the applications of EO in continuous optimization problems are relatively rare. This paper proposes an improved real-coded population-based EO method (IRPEO for continuous unconstrained optimization problems. The key operations of IRPEO include generation of real-coded random initial population, evaluation of individual and population fitness, selection of bad elements according to power-law probability distribution, generation of new population based on uniform random mutation, and updating the population by accepting the new population unconditionally. The experimental results on 10 benchmark test functions with the dimension N=30 have shown that IRPEO is competitive or even better than the recently reported various genetic algorithm (GA versions with different mutation operations in terms of simplicity, effectiveness, and efficiency. Furthermore, the superiority of IRPEO to other evolutionary algorithms such as original population-based EO, particle swarm optimization (PSO, and the hybrid PSO-EO is also demonstrated by the experimental results on some benchmark functions.

  3. Continuously improving safety of nuclear installations: An approach to be reinforced after the Fukushima accident

    Repussard, Jacques; Schwarz, Michel

    2012-05-01

    After the Three Mile Island accident in 1979 and the Chernobyl accident in 1986, the Fukushima accident shows that the probability of a core meltdown accident in an LWR (Light Water Reactor) has been largely underestimated. The consequences of such an accident are unacceptable: except in the case of TMI2 (Three Mile Island 2) large areas around the damaged plants are contaminated for decades and populations have to be relocated for long periods. This article presents the French approach which consists in improving continuously the safety of the Nuclear Power Plants (NPP) on the basis of lessons learned from operating experience and from the progress in R&D (Research and Development). It details the key role played by IRSN (Institut de radioprotection et de sûreté nucléaire), the French TSO (Technical and scientific Safety Organization), and shows how the Fukushima accident contributes to this approach in improving NPP robustness. It concludes on the necessity to keep on networking TSOs, to share knowledge as well as R&D resources, with the ultimate goal of enhancing and harmonizing nuclear safety worldwide.

  4. An improved cross entropy algorithm for steelmaking-continuous casting production scheduling with complicated technological routes

    王桂荣; 李歧强; 王鲁浩

    2015-01-01

    In order to increase productivity and reduce energy consumption of steelmaking-continuous casting (SCC) production process, especially with complicated technological routes, the cross entropy (CE) method was adopted to optimize the SCC production scheduling (SCCPS) problem. Based on the CE method, a matrix encoding scheme was proposed and a backward decoding method was used to generate a reasonable schedule. To describe the distribution of the solution space, a probability distribution model was built and used to generate individuals. In addition, the probability updating mechanism of the probability distribution model was proposed which helps to find the optimal individual gradually. Because of the poor stability and premature convergence of the standard cross entropy (SCE) algorithm, the improved cross entropy (ICE) algorithm was proposed with the following improvements: individual generation mechanism combined with heuristic rules, retention mechanism of the optimal individual, local search mechanism and dynamic parameters of the algorithm. Simulation experiments validate that the CE method is effective in solving the SCCPS problem with complicated technological routes and the ICE algorithm proposed has superior performance to the SCE algorithm and the genetic algorithm (GA).

    2010-07-01

    Full Text Available Abstract Background During the last 35 years the poor ranking of Hungary on the list of life expectancy at birth among European countries, has not changed. In 1970 our lag behind the leading European countries was the smallest. The gap was growing between 1970 and 1993 but from 1994 onwards the life expectancy at birth in Hungary has increased continuously and somewhat faster than in other European countries. The aim of this study was to analyze the association between decreasing cardiovascular mortality rates, as a main cause of death and the increase in cardio-metabolic prescriptions and possible changes in lifestyle behavior. Methods Analyses were conducted on national data concerning cardiovascular mortality and the number of cardio-metabolic drug prescription per capita. The association between yearly rates of cardiovascular events and changes in antihypertensive, antilipidemic and antidiabetic prescription rates was analyzed. The changes in other cardiovascular risk factors, like lifestyle were also considered. Results We observed a remarkable decline of mortality due to stroke and acute myocardial infarction (AMI. The fall was significantly associated with all prescription rates. The proportion of each treatment type responsible for suppression of specific mortality rates is different. All treatment types comparably improved stroke mortality, while antilipidemic therapy improved AMI outcome. Conclusions These results emphasize the importance of a comprehensive strategy that maximizes the population coverage of effective treatments. Hungary appears to be at the beginning of the fourth stage of epidemiologic transition, i.e. it has entered the stage of delayed chronic noninfectious diseases.

    2009-01-01

    Full Text Available Introduction: Close monitoring of arterial blood pressure (BP is a central part of cardiovascular surveillance of patients at risk for hypotension. Therefore, patients undergoing diagnostic and therapeutic procedures with the use of sedating agents are monitored by discontinuous non-invasive BP measurement (NIBP. Continuous non-invasive BP monitoring based on vascular unloading technique (CNAP®, CN Systems, Graz may improve patient safety in those settings. We investigated if this new technique improved monitoring of patients undergoing interventional endoscopy. Methods: 40 patients undergoing interventional endoscopy between April and December 2007 were prospectively studied with CNAP® in addition to standard monitoring (NIBP, ECG and oxygen saturation. All monitoring values were extracted from the surveillance network at one-second intervals, and clinical parameters were documented. The variance of CNAP® values were calculated for every interval between two NIBP measurements. Results: 2660 minutes of monitoring were recorded (mean 60.1±34.4 min/patient. All patients were analgosedated with midazolam and pethidine, and 24/40 had propofol infusion (mean 90.9±70.3 mg. The mean arterial pressure for CNAP® was 102.4±21.2 mmHg and 106.8±24.8 mmHg for NIBP. Based on the first NIBP value in an interval between two NIBP measurements, BP values determined by CNAP® showed a maximum increase of 30.8±21.7% and a maximum decrease of 22.4±28.3% (mean of all intervals. Discussion: Conventional intermittent blood pressure monitoring of patients receiving sedating agents failed to detect fast changes in BP. The new technique CNAP® improved the detection of rapid BP changes, and may contribute to a better patient safety for those undergoing interventional procedures.

    Labouisse Jean-Pierre

    2005-03-01

    Full Text Available From 1962 to 2002, at the Saraoutou research station on the island of Santo in Vanuatu, a hybrid creation programme was implemented to improve the productive potential of coconut cultivars. The first stage was to create a collection by introducing around thirty exotic varieties. All those varieties and most of the 60 hybrids created proved to be susceptible to coconut foliar decay, a viral disease transmitted by Myndus taffini and endemic in Vanuatu. Only the Vanuatu Tall populations and two hybrids (Vanuatu Red Dwarf × Vanuatu Tall and Vanuatu Tall × Rennell Island Tall displayed tolerance enabling their distribution to farmers. The author indicates the origin of the parents and the production characteristics of these two hybrids. The Vanuatu Red Dwarf × Vanuatu Tall hybrid expresses good hybrid vigour with a production potential ranging from 2.5 to 3.4 tons per hectare per year. However, it does have several defects: slow germination and a highly irregular final germinated nut rate, susceptibility to cyclones when young, premature nut fall sometimes seen on young palms, and a mediocre copra content (between 135 and 160 g. The Vanuatu Tall × Rennell Island Tall hybrid stands out through its early start to bearing (4 years, its vigour and its good adaptation to cyclones. The copra content of its nuts (between 210 and 245 g is better than that of the Vanuatu Tall, making copra preparation easier. Its production ranges from 2.5 to 3 tons per hectare per year, which is around 30% better than the improved Vanuatu Tall (Elite Vanuatu Tall. However, dissemination of this hybrid, which can only be produced in centralized seed gardens, is limited by the cost of production and of transport throughout the archipelago. Only large-scale Elite Vanuatu Tall production in decentralized seed gardens would enable a significant improvement in coconut productivity in Vanuatu.

  10. Radiation safety infrastructure in developing countries: a proactive approach for integrated and continuous improvement

    The International Atomic Energy Agency (the Agency) is authorized, by its statute, to establish or adopt safety standards for the protection of health and minimization of danger to life and property, and to provide for their application to its own operations as well as to operations under its control or supervision. The Agency has been assisting, since the mid 1960's, its Member States through mainly its Technical Cooperation Programme (TCP) to improve their national radiation safety infrastructures. However up to the early nineties, assistance was specific and mostly ad hoc and did not systematically utilize an integrated and harmonized approach to achieving effective and sustainable national radiation safety infrastructures in Member States. An unprecedented and integrated international cooperative effort was launched by the Agency in 1994 to establish and/or upgrade the national radiation safety infrastructure in more than 90 countries within the framework of its TCP through the so-called Model Project on Upgrading Radiation Protection Infrastructure. In this project proactive co-operation with Member States was used in striving towards achieving an effective and sustainable radiation safety infrastructure, compatible with the International Basic Safety Standards for Protection against Ionizing Radiation and for the Safety of Radiation Sources (the BSS) and related standards. Extension to include compatibility with the guidance of the Code of Conduct on the Safety and Security of Radioactive Sources occurred towards the end of the Model Project in December 2004, and with the more recent ensuing follow up projects that started in 2005. The Model Project started with 5 countries in 1994 and finished with 91 countries in 2004. Up to the end of 2007 more than one hundred Member States had been participating in follow up projects covering six themes - namely: legislative and regulatory infrastructure; occupational radiation protection; radiation protection in medical

    Full Text Available Research supports the implementation of mentoring programs as potentially successful approaches to meeting the needs of at-risk students. This study examined a mentoring program entitled: LISTEN (Linking Individual Students To Educational Needs. The LISTEN mentoring program was a district-sponsored, school-based program in which at-risk, middle school students were identified by the school system and mentors were recruited specifically to assist these students with school performance or related issues. Mentors, in this study, were classroom teachers, school counselors, administrators, custodians, librarians, teaching assistants, retired teachers, and cafeteria employees. Archival data from the 2003–04 and 2004–05 academic years were analyzed. A statistically significant difference was found for all three of the study’s criterion variables (GPAs, discipline referrals, and attendance records between those measured in the 2003–04 academic year (pre-intervention and those measured in the 2004–05 academic year (post-intervention. Forty-nine of the fifty-four LISTEN participants experienced academic achievement gains in all three areas of the study.

    Santos, J. L.; Esteban, M. J.

    2013-09-01

    We are used to hear a success company in today's world is not possible unless a continuous improvement is developed. How can we be successful in the nuclear plant? We have to achieve safety for workers, people and environment in the first step, and for the second step availability and reliability for systems and components to avoid failure of components that could reduce availability. The aim is to search for new measures to reach this way. One of the improvements implemented in the plants to improve continuously was mainly Operating Experience activities, which was based in event analysis in the plants, causes identification, and to implement corrective actions. For External Operating Experience the aim was to learn from others to avoid occurrence of events in our plants. This was the lessons learned from Three Mile Island event. This was the learning process implemented so far, to get a continuous improvement. So far, the developed capabilities for process improvement follow the Operating Experience process that could be considered classical and will be revitalized nowadays. (Author)

  17. Continuous quality improvement in daily clinical practice: a proof of concept study.

    Jonathan A Lorch

    Full Text Available Continuous Quality Improvement (CQI is an iterative process of: planning to improve a product or process, plan implementation, analyzing and comparing results against those expected, and corrective action on differences between actual and expected results. It is little used in clinical medicine. Anemia, a complex problem in End Stage Renal Disease patients, served to test the ability of an unique electronic medical record (EMR optimized for daily care to empower CQI in practice. We used data collected during daily care, stored in the EMR, and organized to display temporal relationships between clinical, laboratory, and therapeutic events. Our aims were optimal hemoglobin with minimum epoetin, and maintaining stable hemoglobin and epoetin. The study was done on 250 patients treated by maintenance hemodialysis (HD, receiving epoetin prior to February 1, 2010 and followed to July 31, 2011. Repleting iron, ensuring iron sufficiency, slow epoetin reduction, and decision support tools enabling data display over long periods in patient-centered reports were key elements. Epoetin dose, adjusted 6-8 weekly, was based on current clinical conditions and past responses. Hemoglobin increased by months 1-2; epoetin decreased from month 4. By months 16-18, epoetin had decreased 42% to 9,720 units/week while hemoglobin increased 8% to 123.6 g/L. Hemoglobin and epoetin were stable from month 7 onward. New epoetin orders decreased 83%. Transferrin saturation increased after the study start. Individual patient hemoglobin variation decreased by 23%, range by 27%. Mortality, 11.78 per 100 patient years, was 42% less than United States dialysis patient mortality. Allowable epoetin charges decreased by $15.33 per treatment and were $22.88 less than current Medicare allowance. The study validates the hypothesis that an EMR optimized for daily patient care can empower CQI in clinical medicine and serve to monitor medical care quality and cost.

  18. The Influence of a Continuing Medical Education Campaign on New Strategies to Improve Appropriate Use of Antibiotics

    Brenda A. Bucklin

    2015-01-01

    Full Text Available Introduction. Widespread use of antibiotics has led to drug-resistant bacteria and reports of drug-resistant infections. A continuing medical education (CME campaign was used to improve antibiotic use among primary care providers. Methods. The Office of CME and Professional Development at the University of Colorado School of Medicine produces a semiannual, week-long course for primary care providers. A 2-year multifaceted CME campaign consisted of course content on antibiotic use, a practice audit, and two surveys to measure perceptions of the problem of antibiotic overuse, potential barriers to achieving appropriate use, and strategies to overcome barriers. Results. The overall response rate in the 2nd part of the campaign was 68.4%. Sixty-six percent of respondents had implemented at least one strategy to reduce antibiotic overuse. The rate was significantly higher among those who had attended previous reviews (81.0% compared with those who had attended neither (54%, p=0.0002. However, there was no “dose effect” on the rate of implementing a new strategy. Conclusions. Overuse of antibiotic therapy has important public health implications. Results suggest that mixed interactive and didactic CME program was effective in increasing awareness of antibiotic overuse and strategies for reducing antibiotic administration.

  19. Improved dichotomous search frequency offset estimator for burst-mode continuous phase modulation

    Zhai, Wen-Chao; Li, Zan; Si, Jiang-Bo; Bai, Jun

    2015-11-01

    A data-aided technique for carrier frequency offset estimation with continuous phase modulation (CPM) in burst-mode transmission is presented. The proposed technique first exploits a special pilot sequence, or training sequence, to form a sinusoidal waveform. Then, an improved dichotomous search frequency offset estimator is introduced to determine the frequency offset using the sinusoid. Theoretical analysis and simulation results indicate that our estimator is noteworthy in the following aspects. First, the estimator can operate independently of timing recovery. Second, it has relatively low outlier, i.e., the minimum signal-to-noise ratio (SNR) required to guarantee estimation accuracy. Finally, the most important property is that our estimator is complexity-reduced compared to the existing dichotomous search methods: it eliminates the need for fast Fourier transform (FFT) and modulation removal, and exhibits faster convergence rate without accuracy degradation.

    2014-07-01

    Full Text Available Structural equation modeling (SEM has traditionally been deployed in areas of marketing, consumer satisfaction and preferences, human behavior, and recently in strategic planning. These areas are considered their niches; however, there is a remarkable tendency in empirical research studies that indicate a more diversified use of the technique.  This paper shows the application of structural equation modeling using partial least square (PLS-SEM, in areas of manufacturing, quality, continuous improvement, operational efficiency, and environmental responsibility in Mexico’s medium and large manufacturing plants, while using a small sample (n = 40.  The results obtained from the PLS-SEM model application mentioned, are highly positive, relevant, and statistically significant. Also shown in this paper, for purposes of validity, reliability, and statistical power confirmation of PLS-SEM, is a comparative analysis against multiple regression showing very similar results to those obtained by PLS-SEM.  This fact validates the use of PLS-SEM in areas of untraditional scientific research, and suggests and invites the use of the technique in diversified fields of the scientific research

  1. A BLUEPRINT FOR EXECUTING CONTINUAL QUALITY IMPROVEMENT IN AN ENGINEERING UNDERGRADUATE PROGRAMME

    School of Engineering, Taylor’s University, No. 1 Jalan Taylor’s 47500 Subang Jaya, Selangor DE, Malaysia

    2013-04-01

    Full Text Available This paper focuses on providing a template of how to practice Continual Quality Improvement (CQI in an Engineering Undergraduate Programme. At the inception of the programme, the academic curriculum is based upon the notion of the type of graduate an institution of higher learning would like to produce. Hence, a graduate of a particular institution embodies its vision and mission. Taking this further and to ensure specificity in the type of graduate produced, Engineering Programmes provide a set of Programme Educational Objectives (PEOs which are derived from the vision and mission. From these PEOs, the Programme Outcomes (POs are crafted, followed by the Learning Outcomes (LOs at the module level – and hence the appropriate curriculum is decided upon. Once the programme is in full implementation, there exists a need to monitor and control the PEOs, POs and LOs to ensure that the programme progresses and evolves. Herein lies the need to practice CQI at all three levels. The following paper will provide an emphasis of how CQI, implemented correctly can result in enhancing the overall student learning experience.

    Full Text Available Purpose: During the last 50 years industrial companies have adopted continuous improvement systems to improve their competitiveness. However, the maintenance of improvement systems is not an easy matter. Some companies, after an initial period of one to two years, abandon the system for various reasons. This article aims to examine the level of application of Continuous Improvement Systems and the factors which support sustainability over time in two different regions.Design/methodology/approach: In order to obtain a comparative result between two different regions, a survey was conducted in two industrial zones—one in the north of Spain and another in Mexico—that are important industrial clusters these countries. The study was conducted through the analysis of survey data. Specifically, the survey was directed at large industrial enterprises who had participated in activities supported by local foundations for the promotion of quality and improvement.Findings and Originality/value: We suggest the following three keys for sustainable improvement: greater involvement of task forces in the improvement program, a PDCA improvement cycle for improvement and a clear purpose for continuous improvement, integration of the continuous improvement system in the organization, and the establishment of indicators associated with the system.Research limitations/implications: The comparative study focused on only two industrial zones in Spain and Mexico. In that sense, the findings of the research are limited to the Basque zone and geographical zone of Toluca-Lerma.Practical implications: Some of the companies have started to apply some continuous improvement techniques in a sustainability way. Therefore, these findings could be very useful for general and operation managers that are involved in continuous improvement systems in industrial companies in Spain and Mexico.Social implications: As a consequence, slow and small transformations in certain

  6. Assessing the Impact of Continuous Quality Improvement on Clinical Practice: What It Will Take to Accelerate Progress

    Shortell, Stephen M.; Bennett, Charles L.; Byck, Gayle R.

    1998-01-01

    The literature on continuous quality improvement (CQI) has produced some evidence, based on nonrandomized studies, that its clinical application can improve outcomes of care while reducing costs. Its effectiveness is enhanced by a nucleus of physician involvement, individual practitioner feedback, and a supportive organizational culture. The few randomized studies, however, suggest no impact of CQI on clinical outcomes and no evidence to date of organization-wide improvement in clinical perfo...

  7. Hybrid Continuous Wavelet Based Controulet Transform Method for DICOM Image Compression and Improved SPHIT Coding

    C.S. Manikandababu

    2015-03-01

    Full Text Available The widely used standard for medical image storage and transmission is named as Digital Imaging and Communication in Medicine (DICOM. In every field of medicine including diagnosis, treatment, and research, medical images that are obtained as the outputs of the techniques such as the Computerized Tomography (CT, magnetic resonance (MR, digital subtraction angiography (DSA and Ultrasonography (US are saved as DICOM format. Network sharing of these larger sized radiology images require large bandwidth. Hence before transferring, compression of such larger image files is necessary for easy and faster communication even with lower bandwidth. Huge amount of data either in multidimensional or multiresolution form is been created as a result of medical information. This makes the following steps like retrieval, efficient storage, management, and transmission of these data a complex process. This complexity could be reduced by compressing the medical data without any loss. Many methods have been proposed so far for compression of the large DICOM images, however with some limitations. Thus, specific methods to overcome the limitations like reducing the noise of MSE error signal and improving the PSNR value results in the medical images are to be proposed for the study. One such method is referred as Hybrid Weibull Probability Density Function based Continuous Wavelet based controulet transform (WPDF-CWBCT that helps for compression of medical images without any data loss and also for improving the PSNR and reducing the MSE of the signal. The directional filter banks are being applied by initializing using the wavelet transform such that the image coding scheme is maintained based on the proposed transform. WPDF-CWBCT also uses a new set partitioning in hierarchical trees by employing a sorting method (SPIHT algorithm that provided an embedded code. In this method, the diagnostics capabilities are not compromised to ensure the better performance of image

    Full Text Available Premature and high-risk infants require accurate delivery of nutrients to promote appropriate growth. Continuous enteral feeding methods may result in significant fat and micronutrient loss. This study evaluated fat loss in enteral nutrition using current strategies for providing high-risk infants fortified human milk (HM. The fat content of HM was measured by IR analyzer in a simulated feeding system using the Kangaroo epumpTM and the MedFusionTM 2010 pump. Comparisons in fat loss were made between HM, HM supplemented with donor HM-derived fortifier Prolacta + H2MFTM (H2MF, and HM supplemented with H2MF and donor HM-derived cream ProlactCRTM (cream. When using the Kangaroo epumpTM, the addition of H2MF and cream to HM increased fat delivery efficiency from 75.0% ± 1.2% to 83.7% ± 1.0% (p < 0.0001. When using the MedFusionTM 2010 pump, the addition of H2MF to HM increased fat delivery efficiency from 83.2% ± 2.8% to 88.8% ± 0.8% (p < 0.05, and the addition of H2MF and cream increased fat delivery efficiency to 92.0% ± 0.3% (p < 0.01. The addition of H2MF and cream to HM provides both the benefits of bioactive elements from mother’s milk and increased fat delivery, making the addition of H2MF and cream an appropriate method to improve infant weight gain.

  9. Closing the social-class achievement gap: a difference-education intervention improves first-generation students' academic performance and all students' college transition.

    Stephens, Nicole M; Hamedani, MarYam G; Destin, Mesmin

    2014-04-01

    College students who do not have parents with 4-year degrees (first-generation students) earn lower grades and encounter more obstacles to success than do students who have at least one parent with a 4-year degree (continuing-generation students). In the study reported here, we tested a novel intervention designed to reduce this social-class achievement gap with a randomized controlled trial (N = 168). Using senior college students' real-life stories, we conducted a difference-education intervention with incoming students about how their diverse backgrounds can shape what they experience in college. Compared with a standard intervention that provided similar stories of college adjustment without highlighting students' different backgrounds, the difference-education intervention eliminated the social-class achievement gap by increasing first-generation students' tendency to seek out college resources (e.g., meeting with professors) and, in turn, improving their end-of-year grade point averages. The difference-education intervention also improved the college transition for all students on numerous psychosocial outcomes (e.g., mental health and engagement). PMID:24553359

  10. Continuous improvement programs as processes for organizational learning: A case study of a company in the food products industry.

    André Luiz Fischer

    2010-05-01

    Full Text Available This article intends to show the relationships between quality practices and the process of organizational learning. When we look at the literature about programs of continuous improvement, we see that theoreticians consider that the process of organizational learning is a superior stage in the quality culture adopted by companies. To investigate this possibility, we put together a series of indicators taken from classic authors who have written about organizational learning. Adopting a multiple methodology, we applied these indicators to two plants belonging to the Nestlé food product company, which have introduced continuous improvement programs over the last two years.

    In applications in which the high torque per ampere at low speed and rated power at high speed are required, the continuous current method is the best solution. However, there is no report on calculating the core loss of SRM in continuous current mode of operation. Efficiency and iron loss calculation which are complex tasks in case of conventional mode of operation is even more involved in continuous current mode of operation. In this paper, the Switched Reluctance Motor (SRM) is modeled using finite element method and core loss and copper loss of SRM in discontinuous and continuous current modes of operation are calculated using improved analytical techniques to include the minor loop losses in continuous current mode of operation. Motor efficiency versus speed in both operation modes is obtained and compared. - Highlights: • Continuous current method for Switched Reluctance Motor (SRM) is explained. • An improved analytical technique is presented for SRM core loss calculation. • SRM losses in discontinuous and continuous current operation modes are presented. • Effect of mutual inductances on SRM performance is investigated.

    Enhanced vizualization leads to better forest management solutions. This paper discusses the application of numerical remote sensing and geographic information systems to forest inventory. Natural phenomena usually exhibit both continuous and discrete behaviour. Discrete models have been used since the inception of aerial photography, long before the introduction of mathematical statistics, computers or remote sensing but today, forest attributes can also be described as continuous surfaces. ...

  13. Improvement of two-way continuous variable quantum cryptography by using additional noise

    The performance of quantum key distribution such as one-way continuous variable protocols, can be increased by adding some noise on the reference side of error correction in the error-correction phase. For this reason, we here study this possibility in the case of two-way continuous variable system. Finally, the numerical results show that the using of additional noise gives two-way schemes better security performance in terms of secret key rates and resistance to channel excess noise.

    2014-09-01

    Knowledge regarding antimicrobial therapy strategies in deep sternal wound infections (DSWI) following cardiac surgery is limited. Therefore, we aimed to determine the steady-state plasma and mediastinal concentrations of oxacillin administered by continuous infusion in critically ill patients with DSWI and to compare these concentrations with the susceptibility of staphylococci recovered. A continuous infusion of oxacillin (150 to 200 mg/kg of body weight/24 h) was administered after a loading dose (50 mg/kg). Plasma and mediastinal concentrations of total and unbound oxacillin were determined 4 h after the loading dose (H4) and then at day 1 (H24) and day 2 (H48). Twelve patients were included. Nine patients exhibited bacteremia, 5 were in septic shock, 8 were positive for Staphylococcus aureus, and 4 were positive for coagulase-negative staphylococci. The median MIC (first to third interquartile range) was 0.25 (0.24 to 0.41) mg/liter. Median plasma concentrations of total and unbound oxacillin at H4, H24, and H48 were, respectively, 64.4 (41.4 to 78.5) and 20.4 (12.4 to 30.4) mg/liter, 56.9 (31.4 to 80.6) and 21.7 (6.5 to 27.3) mg/liter, and 57.5 (32.2 to 85.1) and 20 (14.3 to 35.7) mg/liter. The median mediastinal concentrations of total and unbound oxacillin at H4, H24, and H48 were, respectively, 2.3 (0.7 to 25.9) and 0.9 (oxacillin delivered by continuous infusion is a valuable strategy to achieve our pharmacokinetic target (4× MIC) at the site of action at H24. But concerns remain in cases of higher MICs, emphasizing the need for clinicians to obtain the MICs for the bacteria and to monitor oxacillin concentrations, especially the unbound forms, at the target site.

  15. Life Improvement of Pot Hardware in Continuous Hot Dipping Processes Final Report

    Xingbo Liu

    2006-01-18

    The process of continuous galvanizing of rolled sheet steel includes immersion into a bath of molten zinc/aluminum alloy. The steel strip is dipped in the molten bath through a series of driving motors and rollers which control the speed and tension of the strip, with the ability to modify both the amount of coating applied to the steel as well as the thickness and width of the sheet being galvanized. There are three rolls used to guide the steel strip through the molten metal bath. The rolls that operate in the molten Zn/Al are subject to a severely corrosive environment and require frequent changing. The performance of this equipment, the metallic hardware submerged in the molten Zn/Al bath, is the focus of this research. The primary objective of this research is to extend the performance life of the metallic hardware components of molten Zn/Al pot hardware by an order of magnitude. Typical galvanizing operations experience downtimes on the order of every two weeks to change the metallic hardware submerged in the molten metal bath. This is an expensive process for industry which takes upwards of 3 days for a complete turn around to resume normal operation. Each roll bridle consists of a sink, stabilizer, and corrector roll with accompanying bearing components. The cost of the bridle rig with all components is as much as $25,000 dollars just for materials. These inefficiencies are of concern to the steel coating companies and serve as a potential market for many materials suppliers. This research effort served as a bridge between the market potential and industry need to provide an objective analytical and mechanistic approach to the problem of wear and corrosion of molten metal bath hardware in a continuous sheet galvanizing line. The approach of the investigators was to provide a means of testing and analysis that was both expeditious and cost effective. The consortium of researchers from West Virginia University and Oak Ridge National Laboratory developed

  4. Mechanism and Application of a New Guard Rail for Improving the Stability of Small Radius Curve Tracks with Continuous Welded Rails

    Mao Jian-Hong

    2014-01-01

    Full Text Available This study studied an effect of a new guard rail on the stability of curve tracks with CWR and revealed a mechanism of the new guard rail for improving the stability of small radius curve tracks with CWR and also analyze the degree of the new guard rail for enlarging the pave range of small radius curve tracks with CWR. In order to achieve these, an improved load-deformation method for calculating the stability of tracks with Continuous Welded Rails (CWR is suggested and verified. The results indicate that the improved load-deformation method not only has the same accuracy as the improved unified formula in specification, but also has the same clear and simple characteristics as the original load-deformation method. The mechanism of the new guard rail for improving the stability of small radius curve tracks with CWR is that the CWR stability can be greatly improved by increasing the stiffness of the track framework under conditions of maintaining the same cross-sectional area of the rails. The CWR with the new guard rail can allow the minimum laying radius from 300 m down to 230 m, i.e., the current specification limit can be relaxed 23.3%. If combined with the roadbed strengthening measures, the new guard rail can allow the minimum laying radius from 300 m down to 140 m, i.e., the current specification limit can be further relaxed 53.3%.

  5. Repeated Self- and Peer-Review Leads to Continuous Improvement in Child Interviewing Performance

    Stolzenberg, Stacia N.; Lyon, Thomas D.

    2016-01-01

    The present study examined whether a training model that focuses on consistent exposure to protocol procedure, self-evaluation, and intensive peer-review sessions could improve interviewers’ ability to adhere to best practices. Law students (N = 19) interviewed 5- to 10-year-old children on a weekly basis as part of a semester-long forensic child interviewing class. They transcribed their interviews, and participated in one-hour self and peer-reviews. The proportion of each question type was calculated (option-posing, Wh-, and open-invitations) within each interview for each interviewer. Across ten weeks of interviews, interviewers consistently improved their performance, decreasing the proportion of option-posing questions by 31% and increasing the proportion of open-invitations by 47%. All interviewers improved. The present study suggests that with consistent self-evaluation and peer-review, forensic interviewers can incrementally improve their performance.

    Huo, Daoan; Cao, Qiang; Xie, Changsheng; Yang, Jing

    2009-08-01

    Data is the core resource of the information system, so that data corruption is one of the key problems which are on top of the radar screen of most information system administrators. Continuous Data Protection (CDP) technologies help them deal with data corruption by providing timely recovery to any point-in-time. But in this CDP process, the CDP system needs record every data changes, and then the extra system I/O operations increase greatly, the performance of information systems will be lower and the system cannot provide the best service. This paper discusses a method based buffer chains that can reduce the extra I/O operations from the disk. We have presented an implementation in the Linux kernel which provides continuous data protection service with higher performance under some buffer chains strategy.

There was a significant group × time interaction for change in work capacity (P<0.001, which increased significantly in CONT (23.8±3.0% and HIIT (22.3±3.5% but not PLA (3.1±5.0%. There was a near-significant main effect for percentage trunk fat, with trunk fat reducing in CONT by 3.1±1.6% and in PLA by 1.1±0.4%, but not in HIIT (increase of 0.7±1.0% (P=0.07. There was a significant reduction in android fat percentage in CONT (2.7±1.3% and PLA (1.4±0.8% but not HIIT (increase of 0.8±0.7% (P=0.04. Conclusion. These data suggest that HIIT may be advocated as a time-efficient strategy for eliciting comparable fitness benefits to traditional continuous exercise in inactive, overweight adults. However, in this population HIIT does not confer the same benefit to body fat levels as continuous exercise training.

    Clemencic, M.; Couturier, B.; Kyriazi, S.

    2015-12-01

    The purpose of this paper is to identify a set of steps leading to an improved interface for LHCb's Nightly Builds Dashboard. The goal is to have an efficient application that meets the needs of both the project developers, by providing them with a user friendly interface, as well as those of the computing team supporting the system, by providing them with a dashboard allowing for better monitoring of the build job themselves. In line with what is already used by LHCb, the web interface has been implemented with the Flask Python framework for future maintainability and code clarity. The Database chosen to host the data is the schema-less CouchDB[7], serving the purpose of flexibility in document form changes. To improve the user experience, we use JavaScript libraries such as JQuery[11].

    2013-05-01

    Full Text Available Over the last decades, an impressive number of conceptual models in the field of educational leadership have emerged; contingency or trait theories, situational, instructional, shared or distributed school leadership approaches, all tried to demonstrate their specific impact on school development and students achievement. The present paper is focused on exploring one of the foremost models, subject of systematic inquiry and controversial debates developed in relation with school or in nonschool organizations: transformational school leadership. The approach is considered a relevant support for school change process. Its contribution is analyzed in comparison with the benefits of other competing models, the aim of the paper being not to establish hierarchies but to gather significant solutions for better schooling. As a reconciliation solution, the integrative leadership model is also advocated.

    Full Text Available Writing is a complex task. The development of students’ writing skill depends on the teacher’s teaching strategy and also the materials used in the writing lesson. In the present study, the effectiveness of a creative writing module was examined that was designed to improve the writing skill of a group of excellent students. It was added with explicit teaching strategies. The selected group of students were students who were in the excellent group but lacked creativity and vocabulary in their writing. The creative writing module was designed to help these students. Students’ improvement was observed through observation in the classrooms during the lessons and through writing task as well as interviews. Two observations were made. One was before the creative writing project was started and another after the completion of the entire task of the module. The interview was carried out to learn about the students’ perception of the module and how do they find the module has helped them.  The result of the research showed that students have shown a great level of improvement in their writing skills. The outcome of this present study could be useful to assist language instructors in helping proficient learners to undergo a more effective second language learning experience.

  11. Operational Improvements of Continuous Process with Tools of Lean Production - A Case Study in a Brazilian Petrochemical

    Francisco Uchoa Passos

    2013-06-01

    Full Text Available This study seeks to evaluate operational improvements in Brazilian petrochemical company Braskem, which has been using lean production management tools to monitor its processes. There was some improvement in plant efficiency, measured from the beginning of implementation of management tools Six Sigma and TPM. Thus, we investigated three efficiency indicators considered by the company of great importance for the competitiveness of the business: the physical loss of products, plant’s energy efficiency, and the utilization rate of assets. The differences observed in these indicators, before and after the use of the tools, were tested for its statistical significance, which revealed that the physical losses of ethylene and plant’s energy efficiency improved, almost reaching the performance considered as class world. As for the utilization rate of assets, although it has evolved positively, still is at a considerable distance from that performance standard. By registering operational improvements in a continuous process plant, with lean production tools, this study indicates that these instruments, even if they have no causal relation with the improvements, are suitable for continuous processes and could have a much broader use, oriented, first of all, by the general approach of process optimization and, somehow, regardless of the nature of productive activity.

  14. Improved yields of full-length functional human FGF1 can be achieved using the methylotrophic yeast Pichia pastoris.

    Fantoni, Adele; Bill, Roslyn M; Gustafsson, Lena; Hedfalk, Kristina

    2007-03-01

    We have produced human fibroblast growth factor 1 (hFGF1) in the methylotrophic yeast Pichia pastoris in order to obtain the large amounts of active protein required for subsequent functional and structural characterization. Four constructs were made to examine both intracellular and secreted expression, with variations in the location of the His6 tag at either end of the peptide. hFGF1 could be produced from all four constructs in shake flasks, but production was optimized by growing only the highest-yielding of these strains, which produced hFGF1 intracellularly, under tightly controlled conditions in a 3 L fermentor. One hundred and eight milligrams of pure protein was achieved per liter culture (corresponding to 0.68 mg of protein per gram of wet cells), the function of which was verified using NIH 3T3 cell cultures. This is a 30-fold improvement over previously reported yields of full-length hFGF1. PMID:17134911

  15. Continuous Improvements to East Coast Abort Landings for Space Shuttle Aborts

    Butler, Kevin D.

    2003-01-01

    Improvement initiatives in the areas of guidance, flight control, and mission operations provide increased capability for successful East Coast Abort Landings (ECAL). Automating manual crew procedures in the Space Shuttle's onboard guidance allows faster and more precise commanding of flight control parameters needed for successful ECALs. Automation also provides additional capability in areas not possible with manual control. Operational changes in the mission concept allow for the addition of new landing sites and different ascent trajectories that increase the regions of a successful landing. The larger regions of ECAL capability increase the safety of the crew and Orbiter.

    A. Mahmutović

    2014-04-01

    Full Text Available This paper has researched into the influence of trace elements in steel, combined with new casting processes, on the microstructure and micro-segregation phenomenon in the case of structural steel. Thermocalc software has been applied for calculation of steel phase. In the paper, close attention has been paid to monitoring of the influence of the cooling rate in regard to solidification time and to the characteristic elements’ segregation coefficient. Higher cooling rates during solidification improve the microstructure and produce positive effects on the metallurgical quality of the steel cast.

    Wang, Fucheng; Zhao, Lei; Fang, Wei; He, Xuan; Chen, Hui; Du, Xing; Chen, Huan

    2015-11-01

    Unfired Al2O3-C slide gate plate refractories bonded with novel silicon-modified phenolic resin (MPR) and additives of Al and Si were prepared. The MPR was synthesized by silica sol via in situ polymerization with lignin-phenolic resin. The results showed that the MPR with corundum owns a better wettability and higher char yield than commercial resin (CR). The middle-temperature mechanical properties such as cold modulus of rupture (CMOR), flexural modulus ( E), and force-displacement of Al2O3-C refractory specimens bonded with MPR were improved especially ranging from 673 K to 1073 K (400 °C to 800 °C). The results showed that CMOR of the specimens bonded with MPR coked at 873 K (600 °C) had a considerable improvement with 7.04 MPa in sharp contrast to 3.31 MPa for CR-bonded specimens. It was suggested that the special organic-inorganic network structure of MPR and good wettability with corundum enhanced the bonding strength of Al2O3-C slide gate plate refractories.

    2009-05-15

    Due to the renewed interest in finding sustainable fuels or energy carriers, biohydrogen (Bio-H{sub 2}) from biomass is a promising alternative. Fermentative Bio-H{sub 2} production was studied in a continuous stirred tank reactor (CSTR) operated during 65.6 d with cheese whey (CW) as substrate. Three hydraulic retention times (HRTs) were tested (10, 6 and 4 h) and the highest volumetric hydrogen production rate (VHPR) was attained with HRT of 6 h. Therefore, four organic loading rates (OLRs) at a fixed HRT of 6 h were tested thereafter, being: 92.4, 115.5, 138.6 and 184.4 g lactose/L/d. The highest VHPR (46.61 mmol H{sub 2}/L/h) and hydrogen molar yield (HMY) of 2.8 mol H{sub 2}/mol lactose were found at an OLR of 138.6 g lactose/L/d; a sharp fall in VHPR occurred at an OLR of 184.4 g lactose/L/d. Butyric, propionic and acetic acids were the main soluble metabolites found, with butyric-to-acetic ratios ranging from 1.0 to 2.4. Bacterial community was identified by partial sequence analysis of the 16S rRNA and polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE). The results showed that at HRT of 10 h and 6 h were dominated by the Clostridium genus. The VHPR attained in this study is the highest reported value for a CSTR system using CW as substrate with anaerobic sludge as inoculum and represents a 33-fold increase compared to a previous study. Thus, it was demonstrated that continuous fermentative Bio-H{sub 2} production from CW can be significantly enhanced by an appropriate selection of parameters such as HRT and OLR. Enhancements in VHPR are significant because it is a critical parameter to determine the full-scale practical application of fermentation technologies that will be used for sustainable and clean energy generation.

  20. Clinical audit as a tool of continuous improvement of quality in radiology

    Medical diagnosis and treatment including X -rays, nuclear medicine and radiotherapy , are the largest man-made sources of radiation exposure. The medical use of ionising radiation continues to expand, and is moving towards more complex procedures entailing higher exposures. Directive 97/43/EURATOM, on health protection of individuals against the dangers of ionizing radiation in relation to medical exposures acknowledged that medical practices using ionizing radiation are developing rapidly and that they are from a radiation protection point of view of regulatory concern. Our contribution summarizes the main recommendations of the Guidelines and the major problems of implementation of Clinical audits in Slovakia, which are: Incomplete national legislation for clinical audit; Methods of financing; Lack of formal framework of auditing; Poor understanding of the purpose and contents of clinical audits; Lack of criteria for the standards of good practices; Difficulty to employ sufficient number of auditors; Insufficient time available for auditors; Lack of specific training of auditors; Need of technological modernization of radiology equipment to meet quality standards. The need for harmonization of clinical audits has been recognized by all countries which replied to the questionnaire, including Slovakia and therefore it should be implemented in radiation protection regulations of Health ministry.

  1. Continuous improvement of operation and maintenance conditions of french PWR nuclear islands

    Improvement of the nuclear island design, to facilitate maintenance and working conditions during plant shutdown, has been a subject of particular attention within the French PWR program. Standardization and industrial concentration created an unusually favourable context for approaching this objective. Progress efforts supported by the feedback of actual operating experience were pursued in the areas of plant layout-equipment installation, and on the design and technology of the component themselves. The progress efforts on the design and technology of the components were pursued along several paths including: - the resistance increase of specific parts submitted to various forms of in-service damage, - the reduction of the extent and duration of work during plant outages and - the reduction of the Occupational Radiation Exposure (ORE), one of the most important axes of development, through the appropriate selection of less releasing materials, the implementation of more efficient decontamination systems and by the use of robots

  2. Note: Continuing improvements on the novel flat-response x-ray detector

    This note describes multi-updates of the novel flat-response x-ray detector in fabrication technology, experimental application, and data uncertainty evaluation. Unlike the previous design, the compound filter is combined into one piece through an improved fabrication process that greatly enhanced its self-supporting capability. A method of pinhole-array imaging is introduced into the experimental application process to stop any debris from the hohlraum and to uniformly reduce the radiation flux. The experimental results show that this method works well. Furthermore, a method of uncertainty evaluation of the radiation flux measurement by the novel flat-response x-ray detector has been developed. The influence of the radiation spectrum to the flux measurement is analyzed. The evaluation shows that the relative uncertainty of the radiation flux is about 10% in higher radiation temperature condition (Tr > 150 eV) and 16% in lower radiation temperature condition (Tr < 100 eV).

  3. Continuous intratracheal insufflation of oxygen improves the efficacy of mechanical chest compression-active decompression CPR.

    Steen, Stig; Liao, Qiuming; Pierre, Leif; Paskevicius, Audrius; Sjöberg, Trygve

    2004-08-01

    The aim of the present study was to compare the efficacy of intratracheal continuous insufflation of oxygen (CIO) with intermittent positive pressure ventilation (IPPV) regarding gas exchange and haemodynamics during mechanical chest compression-active decompression cardiopulmonary resuscitation (mCPR) provided by the LUCAS device. Ventricular fibrillation (VF) was induced electrically and ventilation was discontinued in 16 pigs, mean body weight 23 kg (range 22-27 kg). They were randomized into two groups (CIO versus IPPV). After 8 min of VF, mCPR was started and run for 30 min in normothermia, after which defibrillation was attempted during on-going mCPR. Return of spontaneous circulation was obtained in eight of eight CIO pigs and in four of eight IPPV pigs. Arterial oxygen tension (P < 0.05) and coronary perfusion pressure (P < 0.01) were significantly higher in the CIO pigs. Arterial CO(2)-tension was subnormal in both groups and significantly (P < 0.05) lower in the IPPV-pigs (around 4.5 versus 3.0 kPa). The intratracheal pressure differed significantly (P < 0.001) between the two groups. It was negative in each decompression phase in the IPPV pigs in spite of 6 mmHg of PEEP. The CIO pigs had a positive intratracheal pressure during the whole cycle of mCPR, with a minimum pressure of 8 mmHg during each decompression phase. To conclude, mCPR combined with CIO gave adequate ventilation and significantly better oxygenation and coronary perfusion pressure than mCPR combined with IPPV. PMID:15294408

  4. Assessing the Impact of Continuous Quality Improvement on Clinical Practice: What It Will Take to Accelerate Progress

    Shortell, Stephen M.; Bennett, Charles L.; Byck, Gayle R.

    1998-01-01

    The literature on continuous quality improvement (CQI) has produced some evidence, based on nonrandomized studies, that its clinical application can improve outcomes of care while reducing costs. Its effectiveness is enhanced by a nucleus of physician involvement, individual practitioner feedback, and a supportive organizational culture. The few randomized studies, however, suggest no impact of CQI on clinical outcomes and no evidence to date of organization-wide improvement in clinical performance. Further, most studies address misuse issues and avoid examining overuse or underuse of services. The clinical application of CQI is more likely to have a pervasive impact when it takes place within a supportive regulatory and competitive environment, when it is aligned with financial incentives, and when it is under the direction of an organizational leadership that is committed to integrating all aspects of the work.

    2009-07-01

    This paper aims to present a proposal for improving the performance of continuation power flow. For this propose the addition of an equation of one straight line in the plane formed by the load factor variables and bus voltage magnitude. It becomes possible with this, more precise determination of the maximum loading point without calculating a large number of points P-V curve. The work also shows that it is possible to obtain a reduction in computing time required for obtain P-V curve. The reduction is achieved by upgrading Jacobian matrix only when the system suffer some significant change (changing the type of PV bar to PQ or vice versa), instead of updating it at each iteration.

  7. A review of strategies for improving the degradation properties of laminated continuous-fiber/epoxy composites with carbon-based nanoreinforcements

    Lubineau, Gilles

    2012-06-01

    Continuous-fiber/epoxy-matrix laminated composites are a key structural material for aeronautical and aerospace applications. Introducing nanoscale reinforcements to these materials is a possible way to achieve improved mechanical properties. To date, much work has been done on nano-reinforced polymers. However, few systematic studies concerning the effect of the nanoreinforcements on the mechanical properties on laminated composites were conducted. This paper presents a systematic review of the mechanisms of degradation in laminated structures and considers various nanoreinforcement strategies in the light of well-known mechanisms of degradation and phenomenologies in classical laminated composites. We also discuss various nanoreinforcement strategies in terms of their potential to reduce degradation on every scale. In addition, we review studies conducted on the role that nanoreinforcements play in mechanical properties involved in structural simulation and design. The degradation mechanisms are systematically considered to provide a full picture of each reinforcement strategy. © 2012 Elsevier Ltd. All rights reserved.

  8. Continuous improvement of the regulatory framework for the control of medical exposure

    One of the key elements to guide the improvement of the regulatory control is the availability of a self-assessment tool for regulatory performance. Although there is general guidance on self-assessment for regulators and users (IAEA), there is a need for more specific advice on how to address challenges and difficulties faced by regulatory bodies, when regulating radiation protection of patients. Examples of these challenges are the need for regulatory initiatives, in cooperation with health and education authorities, professional bodies and equipment suppliers, and to put in place necessary elements that are beyond responsibility of individual user of radiation, to enable them compliance with safety standards. Purpose: Within the programme of the Ibero American Forum of Nuclear and Radiation Safety Regulatory Organizations, a project to develop such a self-assessment tool for the regulatory control of medical exposure has been designed. Method: National experiences in transposing and enforcing the international radiation safety standards, as to how the requirements are included in national regulations are reviewed. Further, difficulties to the implementation of safety requirements are analyzed and a self-assessment approach and possible regulatory solutions a are presented. Results and discussion: In this study the following documents are being produced: 1) transposition of international requirements into national regulations in the six countries of the Forum, 2) difficulties to implement and enforce the requirements, 3) guidance on self-assessment of regulatory framework for medical exposure, 4) suggested contribution to the revision of international radiation safety standards.

  9. Real-time tracking data drive process improvements, even while ED volumes continue to climb.

    2012-06-01

    Christiana Hospital in Newark, DE, has been able to dramatically reduce length-of-stay in the ED by making use of data derived from a real-time location system (RTLS) that tracks the movements of patients, providers, and staff. Administrators say that while some efficiencies are gained from the system alone, most of the positive impact is derived from using the RTLS data to focus on specific processes and make refinements. Within one year of implementing the RTLS technology, LOS in the ED was reduced by 40 minutes for admitted patients and 18 to 20 minutes for the treated-and-released population. A work group focused on process improvements in the ED's fast track section reduced the average LOS from 2.5 hours to 60 minutes or less. Similarly, a work group focused on the ESI 3 population reduced the average treatment time for this population from 5 or 6 hours to 3.4 hours. Administrators say key steps toward a successful RTLS implementation are careful planning for how you want to use the technology, and alleviating staff concerns about why their movements are being tracked.

  10. Continuing with the Fresnel database: experimental setup and improvements in 3D scattering measurements

    In this paper, the experimental setup and the improvements required to obtain further measurements for the third opus of the Fresnel Database are presented. The most original feature of those new datasets is the fact that they were obtained with three-dimensional targets instead of the two-dimensional ones used in the two previous opuses. The measurements were performed all around the targets under test to collect enough information about the objects to be able to perform inversion on their scattered fields. As the targets were small in comparison with the wavelength, the challenge here was to extract these small scattered fields from the measurements, and a specific post-processing procedure had to be designed to compensate for the drift errors. The five targets selected for the database are presented, including the Myster target, a hitherto undivulged target that is presented in this paper for the first time, i.e., at the same time as the submissions of all the other contributors to this special section. Some scattered field comparisons are also presented

    2010-07-01

    To increase output and meet customers' needs, companies have turned to the development of production management systems: Kaizen, one piece flow, Kanban, etc. The aim of such systems is to accelerate decisions, react to environmental issues and manage various productions. In the main, this type of management system has led to the continuous improvement of production performance. Consequently, such production management systems can have unexpected negative effects on operators' health and safety. Conversely, regulation and control systems focusing on work-related risks have obliged firms to implement health and safety management systems such as OHSAS 18001. The purpose of this type of system, also based on continuous improvement, is to reduce risks, facilitate work-related activities and identify solutions in terms of equipment and tools. However, the prevention actions introduced through health and safety systems often result in other unexpected and unwanted effects on production. This paper shows how companies can improve the way they are run by taking into account both types of management system. PMID:20097327

  14. An improved fiber tracking algorithm based on fiber assignment using the continuous tracking algorithm and two-tensor model

    Liuhong Zhu; Gang Guo

    2012-01-01

    This study tested an improved fiber tracking algorithm, which was based on fiber assignment using a continuous tracking algorithm and a two-tensor model. Different models and tracking decisions were used by judging the type of estimation of each voxel. This method should solve the cross-track problem. This study included eight healthy subjects, two axonal injury patients and seven demyelinating disease patients. This new algorithm clearly exhibited a difference in nerve fiber direction between axonal injury and demyelinating disease patients and healthy control subjects. Compared with fiber assignment with a continuous tracking algorithm, our novel method can track more and longer nerve fibers, and also can solve the fiber crossing problem.

    treatment ways using biotherapic T. cruzi 17DH showed differences in the clinical evolution. The treatment using biotherapic diluted in water initially shows hypothermia, with subsequent recovery of normal temperature (p=0.05 (Fig1. The weight curve shows a better evolution in mice treated with water compared to control groups (p=0.055 and the groups treated by gavage (p=0.0064. Feed and water intake did not differ among the groups. While the mice that were treated with biotherapic diluted in water showed a slight level of ruffled fur, the mice in control groups and the ones treated by gavage showed a more intense level of ruffled fur (p=0.00001. The difference in the evolution of mortality among the groups was significant (p=0.034, while in the group treated with biotherapic diluted with water, the mortality rate started later, reaching the maximum of 90%. This group showed a better clinical result, expressed by the smaller extent of ruffled fur, a better evolution of the temperature curve and higher gain of weight. This is an important result because the Y strain of T. cruzi has a mortality rate of 100% in mice, showing once again the good performance of biotherapic in this model of infection. Conclusion: The use of biotherapic T. cruzi 17DH for a long period causes clinical improvement of the infected mice with Trypanosoma cruzi. The clinical use of these results in human beings should consider the allometric medicine dosage which takes into account the metabolic rate of each organism.

  16. [A New Method for Eliminating Background Signal Drift to Improve the Detection Precision in Continuous Harmonic Detection].

    Zhao, Ying; Zhao, Xue-hong; Wang, Zhe; Zhang, Rui; Wang, Yan

    2015-11-01

    To overcome the second harmonic background signal drift in gas continuous detection based on tunable diode laser absorption spectroscopy(TDLAS), a new method of background elimination was proposed by changing center current of the laser. This method can eliminated the effects of background signal drifting on concentration inversion. Based on the wavelength modulation theory, the theoretical expression of the second harmonic of the background signal is derived. In addition, the second harmonic background signal components and the factors that affect it are described. In different working temperatures, the relationship curve between thelaser current and output light intensity. In the process of continuous detection, we analyzes the feasibility ofchangingthe laser center current extraction of background signal. Combined with the principle of the background signal searching, the LabView flow chart was designed to search background center current. Ammonia (NH₃) was detected by the TDLAS experimental system, which demonstrated the feasibility of the new method. The range of experiment parameters and the range of background center current searches were determined, in the situation that there was only one absorption line in the full laser workspace. The experimental results showed that this method realizes background signal extraction, reduces the error of concentration inversion and the effects of concentration inversion bybackground signal. Thus it improved the detection accuracy of the concentration. In the continuous detection experiment, the standarddeviation of inversion concentration reduced from 2.688 3 to 1.856 1, which demonstrated. that the degree of dispersion of detected concentration is reduced, even eliminate the effects of background signal drifting on concentration inversion and the accuracy of detection is improved. This method provides an effective background drifting elimination approach for improving the detection accuracy of the concentration. PMID

  17. Obtaining accreditation by the pharmacy compounding accreditation board, part 3: developing a program of qualtity assurance and continuous qualtiy improvement.

    Cabaleiro, Joe

    2008-01-01

    Before a compounding pharmacy can receive accreditation from the Pharmacy Compounding Accreditation Board, the pharmacy must show evidence of both quality assurance activities and continuous quality improvement activities. Although quality assurance data gathering and monitoring can be integrated into pharmacy activities fairly easily, the coninuous quality improvement program may take a little more time and effort to implement . Before integrating these programs, compounding pharmacists must have a complete understanding of the differences between these two programs. Even if accreditation with the Pharmacy Compounding Accreditation Board is not being considered, it is important that compounding pharmacies have these two programs implemented. In the long run, it will pay off in higher quality services, error prevention, and perhaps greater efficiency of pharmacy operations. PMID:23969712

  19. Improved Minimum Entropy Filtering for Continuous Nonlinear Non-Gaussian Systems Using a Generalized Density Evolution Equation

    Jinliang Xu

    2013-06-01

    Full Text Available This paper investigates the filtering problem for multivariate continuous nonlinear non-Gaussian systems based on an improved minimum error entropy (MEE criterion. The system is described by a set of nonlinear continuous equations with non-Gaussian system noises and measurement noises. The recently developed generalized density evolution equation is utilized to formulate the joint probability density function (PDF of the estimation errors. Combining the entropy of the estimation error with the mean squared error, a novel performance index is constructed to ensure the estimation error not only has small uncertainty but also approaches to zero. According to the conjugate gradient method, the optimal filter gain matrix is then obtained by minimizing the improved minimum error entropy criterion. In addition, the condition is proposed to guarantee that the estimation error dynamics is exponentially bounded in the mean square sense. Finally, the comparative simulation results are presented to show that the proposed MEE filter is superior to nonlinear unscented Kalman filter (UKF.

  20. Improvements in SIMS continue

    Cluster ion bombardment is at the forefront of current ToF-SIMS research, particularly when examining the feasibility of molecular depth profiling and three-dimensional imaging applications. It has become increasingly clear that secondary ion emission after cluster projectile impact results from a radically different sputtering mechanism than the linear collision cascades that dominate after atomic ion bombardment. The new physics involved with cluster ion impacts dramatically change the traditional approaches toward sample analysis with the SIMS technique. Several new ion bombardment properties have emerged from experimental and theoretical work involving cluster ions such as Au3+, Bi3+, SF5+, and C60+-all of which are commercially available ion sources. These new properties lead to new rules for traditional static SIMS experiments, provoking new methodologies, and introducing new applications-especially where high mass sensitivity and high-resolution imaging of organic and biological materials are necessary. This paper aims to elucidate recent experimental and theoretical work on these new cluster ion properties and offers insights into how these special properties can be used for future experiments and applications

  2. Improved cellulose conversion to bio-hydrogen with thermophilic bacteria and characterization of microbial community in continuous bioreactor

    Thermophilic hydrogen fermentation of cellulose was evaluated by a long term continuous experiment and batch experiments. The continuous experiment was conducted under 55 °C using a continuously stirred tank reactor (CSTR) at a hydraulic retention time (HRT) of 10 day. A stable hydrogen yield of 15.4 ± 0.23 mol kg−1 of cellulose consumed was maintained for 190 days with acetate and butyrate as the main soluble byproducts. An analysis of the 16S rRNA sequences showed that the hydrogen-producing thermophilic cellulolytic microorganisms (HPTCM) were close to Thermoanaerobacterium thermosaccharolyticum, Clostridium sp. and Enterobacter cloacae. Batch experiment demonstrated that the highest H2 producing activity was obtained at 55 °C and the ultimate hydrogen yield and the metabolic by-products were influenced greatly by temperatures. The effect of temperature variation showed that the activation energy for cellulose and glucose were estimated at 103 and 98.8 kJ mol−1, respectively. - Highlights: • Continuous cellulosic-hydrogen fermentation was conducted at 55 °C. • Hydrogen yield was improved to 15.4 mol kg−1 of consumed-cellulose. • The cellulosic hydrogen bacteria were close to Clostridia and Enterobacter genus. • The mixed microflora produced H2 within a wide range of temperatures (35 °C–65 °C). • Activation energy of cellulose and glucose were 103 and 98.8 kJ mol−1, respectively

    Moore, Dale A; Sischo, William M; Kurtz, Suzanne; Siler, Julie D; Pereira, Richard V; Warnick, Lorin D; Davis, Margaret A

    2016-01-01

    The increasing size and complexity of US dairy farms could make it more difficult for a veterinary practitioner to effectively communicate protocol recommendations for prevention or treatment on the farm. A continuing education workshop was set up based on the results of research on dairy organizational communication on dairy farms, which resulted in a tool to assess dairy communication structure and flow. The workshop specifically focused on communication structure and whom to talk to when implementing health care changes in calf rearing. In addition, modern methods of veterinary-client communication knowledge and skills were provided. Primary outcomes of the workshops were to obtain feedback from participants about research findings and the communication model, to improve awareness about the complexity of communication structures on dairy farms, and to change participants' knowledge and skills associated with on-farm communication by providing communication theory and skills and an approach to evaluate and improve dairy organizational communication. Of the 37 participants completing the pre-program assessment, most recognized a need for themselves or their practice to improve communication with clients and farm employees. After the program, most participants were confident in their new communication skills and would consider using them. They highlighted specific new ideas they could apply in practice, such as conducting a "communication audit." The results from the assessment of this communication workshop, focused on dairy veterinarians, highlighted the need for communication training in this sector of the profession and practitioners' desire to engage in this type of training.

    Candas, Bernard; Jobin, Gilles; Dubé, Catherine; Tousignant, Mario; Abdeljelil, Anis Ben; Grenier, Sonya; Gagnon, Marie-Pierre

    2016-01-01

    Background and aim: Continuous quality improvement (CQI) programs may result in quality of care and outcome improvement. However, the implementation of such programs has proven to be very challenging. This mixed methods systematic review identifies barriers and facilitators pertaining to the implementation of CQI programs in colonoscopy services and how they relate to endoscopists, nurses, managers, and patients. Methods: We developed a search strategy adapted to 15 databases. Studies had to report on the implementation of a CQI intervention and identified barriers or facilitators relating to any of the four groups of actors directly concerned by the provision of colonoscopies. The quality of the selected studies was assessed and findings were extracted, categorized, and synthesized using a generic extraction grid customized through an iterative process. Results: We extracted 99 findings from the 15 selected publications. Although involving all actors is the most cited factor, the literature mainly focuses on the facilitators and barriers associated with the endoscopists’ perspective. The most reported facilitators to CQI implementation are perception of feasibility, adoption of a formative approach, training and education, confidentiality, and assessing a limited number of quality indicators. Receptive attitudes, a sense of ownership and perceptions of positive impacts also facilitate the implementation. Finally, an organizational environment conducive to quality improvement has to be inclusive of all user groups, explicitly supportive, and provide appropriate resources. Conclusion: Our findings corroborate the current models of adoption of innovations. However, a significant knowledge gap remains with respect to barriers and facilitators pertaining to nurses, patients, and managers. PMID:26878037

  11. Efficacy of an integrated continuing medical education (CME) and quality improvement (QI) program on radiation oncologist (RO) clinical practice

    Purpose: There has been little radiation oncologist (RO)-specific research in continuing medical education (CME) or quality improvement (QI) program efficacy. Our aim was to evaluate a CME/QI program for changes in RO behavior, performance, and adherence to department protocols/studies over the first 12 months of the program. Methods and Materials: The CME/QI program combined chart audit with feedback (C-AWF), simulation review AWF (SR-AWF), reminder checklists, and targeted CME tutorials. Between April 2003 and March 2004, management of 75 patients was evaluated by chart audit with feedback (C-AWF) and 178 patients via simulation review audit (SR-AWF) using a validated instrument. Scores were presented, and case management was discussed with individualized educational feedback. RO behavior and performance was compared over the first year of the program. Results: Comparing the first and second 6 months, there was a significant improvement in mean behavior (12.7-13.6 of 14, p = 0.0005) and RO performance (7.6-7.9 of 8, p = 0.018) scores. Protocol/study adherence significantly improved from 90.3% to 96.6% (p = 0.005). A total of 50 actions were generated, including the identification of learning needs to direct CME tutorials, the systematic change of suboptimal RO practice, and the alteration of deficient management of 3% of patients audited during the program. Conclusion: An integrated CME/QI program combining C-AWF, SR-AWF, QI reminders, and targeted CME tutorials effectively improved targeted RO behavior and performance over a 12-month period. There was a corresponding increase in departmental protocol and study adherence

  12. Semicoherent searches for continuous gravitational waves: improving robustness versus transient disturbances and increasing sensitivity to transient signals

    Keitel, David

    2015-01-01

    The vulnerability of standard detection methods for long-duration quasi-monochromatic gravitational waves from non-axisymmetric rotating neutron stars ('continuous waves', CWs) to single-detector instrumental artifacts was addressed in past work [Keitel, Prix, Papa, Leaci and Siddiqi, Phys. Rev. D 89, 064023 (2014)] by a Bayesian approach. An explicit model of persistent single-detector disturbances led to a generalized detection statistic with improved robustness against such artifacts. Since many strong outliers in semicoherent searches of LIGO data are caused by transient disturbances that last only a few hours, we extend this approach to cover transient disturbances, and demonstrate increased robustness in realistic simulated data. Besides long-duration CWs, neutron stars could also emit transient signals which, for a limited time, also follow the CW signal model (tCWs). As a pragmatic alternative to specialized transient searches, we demonstrate how to make standard semicoherent CW searches more sensitiv...

  14. Improving the performance of continuous variable quantum key distribution using fading effects of free-space channel

    Zhang, Zeyu; Zhu, Chengrui; He, Guangqiang

    2015-08-01

    Quantum key distribution can be used to share secret keys with information-theoretic security between two legitimate partners for secure communication. In the case of satellite communication, free-space channel is the only way to transmit information, thus research on its properties is of great significance to quantum cryptographic communication. In this paper, we thoroughly analyze the influence of free-space channel fading effects on continuous variable quantum key distribution and for the first time prove that random distribution (such as Rayleigh distribution, Rice distribution and et al.) of free-space channel fading coefficients can be used to increase secret information rates and improve system stability against excess noises. Our results offer academic reference for practical applications of ground-space and space-space quantum communication and global quantum communication network.

    2015-01-15

    Systematic studies of silver nanoparticle synthesis in a continuous-flow single-mode microwave reactor using polyol process were performed, revealing that the synthesis is exceptionally effective to give very small metal particles at full reaction yield and very high productivity. Inlet concentration of silver nitrate or silver acetate, applied as metal precursors, varied between 10 and 50 mM, and flow rates ranged from 0.635 to 2.5 dm{sup 3}/h, to give 3–24 s reaction time. Owing to its much higher reactivity, silver acetate was shown to be far superior substrate for the synthesis of small (10–20 nm) spherical silver nanoparticles within a few seconds. Its restricted solubility in ethylene glycol, applied as the solvent and reducing agent, appeared to be vital for effective separation of the stage of particle growth from its nucleation to enable rapid synthesis of small particles in a highly loaded system. This was not possible to obtain using silver nitrate. All the observations could perfectly be explained by a classical LaMer–Dinegar model of NPs’ formation, but taking into account also nonisothermal character of the continuous-flow process and acetate dissolution in the reaction system. The performed studies indicate an optimal strategy for the high-yield fabrication of metal particles using polyol method.

  1. Study on the improved accuracy of strip profile using numerical formula model in continuous cold rolling with 6-high mill

    The quality requirements for thickness accuracy in cold rolling continue to become more stringent. In cold rolling mill, it is very important that the rolling force calculation considers rolling conditions. The rolled strip thickness was predicted using calculated rolling force. However, the prediction of strip thickness in cold rolling is very difficult; in particular, for 6-high mill with shifted intermediate roll (IMR), the accuracy of thickness is not good. In this study, to improve the accuracy of rolled strip thickness, the roll gap flattening can be given based on Hertz contact theory, with contact between rolls and the smooth cylindrical rolls for the rolling elastic deformation. Also, the distribution of the roll gap flattening may be calculated using the contact force of unit transverse length. The strip profile at the continuous cold rolling is calculated by using the numerical analysis model considering the initial strip profile before cold rolling. Hence, we propose that the numerical model can predict the rolled strip profile more quickly and accurately and be applicable to the field. The results of the proposed numerical model were verified by FE-simulation and cold rolling experiments of 6-high mill with five stands

  5. Technological innovations and design improvements to achieve ALARA exposures in Tarapur Atomic Power Station 3 and 4 (540 MWe)

    Exposure control at the operating Nuclear Power Station is a major concern. Tarapur Atomic Power Station(TAPS) Unit- 3 and 4 is the first Pressurized Heavy Water Reactor of 540 MWe electrical capacity in-depth review of radiation safety was done to identify the impact of design modification on dose rates. Based on the experience gained in the operation of 220 MWe design modifications incorporated in TAPS unit-3 and 4. The challenging task of meeting the International standards in the field of radiation protection had been achieved at Tarapur Atomic Power Station 3 and 4 right from the initial stages of commissioning and operation. To avoid any unplanned exposures and also to keep the exposures at low level, several innovative features were introduced. These efforts were useful in achieving the lowest collective dose in the first year of operation among the Indian Nuclear Power Plants. This paper presents the brief descriptions of the systems and communication strategies adopted and design modifications implemented to reduce the dose rates and controlling exposure at TAPS 3 and 4.

  6. Animation-Based Teaching of Semiconductor Devices: Long-Term Improvement in Students’ Achievements in a Two-Year College

    Aharon Gero

    2015-02-01

    Full Text Available The structure and operating principle of semiconductor devices are a central topic in teaching electronics, both in universities and in two-year colleges. Teachers teaching this subject normally run into substantial difficulties stemming from the fact that a major part of the concepts and processes that are relevant to understanding these devices are abstract. In light of the advantages of multimedia in illustrating dynamic processes, the chapter covering the field effect transistor (FET has recently been taught through animation at a two-year college in Israel. The study presented here has examined, through quantitative tools, whether animation-based teaching of the FET had any effect on students’ achievements in the subject of basic electronic devices. Forty electronics students have participated in the study. Its findings indicate that in the short and long term alike, the achievements of students who studied the transistor through animation were significantly higher than those of their peers who studied it through a traditional method. Additionally, the effect size was very large.

  7. Monitoring Hip and Elbow Dysplasia achieved modest genetic improvement of 74 dog breeds over 40 years in USA.

    Yali Hou

    Full Text Available Hip (HD and Elbow Dysplasia (ED are two common complex developmental disorders of dogs. In order to decrease their prevalence and severity, the Orthopedic Foundation for Animals (OFA has a voluntary registry of canine hip and elbow conformation certified by boarded radiologists. However, the voluntarily reports have been severely biased against exposing dogs with problems, especially at beginning period. Fluctuated by additional influential factors such as age, the published raw scores barely showed trends of improvement. In this study, we used multiple-trait mixed model to simultaneously adjust these factors and incorporate pedigree to derive Estimated Breeding Values (EBV. A total of 1,264,422 dogs from 74 breeds were evaluated for EBVs from 760,455 hip scores and 135,409 elbow scores. These EBVs have substantially recovered the reporting bias and the other influences. Clear and steady trends of genetic improvement were observed over the 40 years since 1970. The total genetic improvements were 16.4% and 1.1% of the phenotypic standard deviation for HD and ED, respectively. The incidences of dysplasia were 0.83% and 2.08%, and the heritabilities were estimated as 0.22 and 0.17 for hip and elbow scores, respectively. The genetic correlation between them was 0.12. We conclude that EBV is more effective than reporting raw phenotype. The weak genetic correlation suggested that selection based on hip scores would also slightly improve elbow scores but it is necessary to allocate effort toward improvement of elbow scores alone.

    2010-10-01

    Full Text Available Abstract Background Improving the health of school-aged children can yield substantial benefits for cognitive development and educational achievement. However, there is limited experimental evidence on the benefits of school-based malaria prevention or how health interventions interact with other efforts to improve education quality. This study aims to evaluate the impact of school-based malaria prevention and enhanced literacy instruction on the health and educational achievement of school children in Kenya. Design A factorial, cluster randomised trial is being implemented in 101 government primary schools on the coast of Kenya. The interventions are (i intermittent screening and treatment of malaria in schools by public health workers and (ii training workshops and support for teachers to promote explicit and systematic literacy instruction. Schools are randomised to one of four groups: receiving either (i the malaria intervention alone; (ii the literacy intervention alone; (iii both interventions combined; or (iv control group where neither intervention is implemented. Children from classes 1 and 5 are randomly selected and followed up for 24 months. The primary outcomes are educational achievement and anaemia, the hypothesised mediating variables through which education is affected. Secondary outcomes include malaria parasitaemia, school attendance and school performance. A nested process evaluation, using semi-structured interviews, focus group discussion and a stakeholder analysis will investigate the community acceptability, feasibility and cost-effectiveness of the interventions. Discussion Across Africa, governments are committed to improve health and education of school-aged children, but seek clear policy and technical guidance as to the optimal approach to address malaria and improved literacy. This evaluation will be one of the first to simultaneously evaluate the impact of health and education interventions in the improvement of

    2013-11-01

    Since ratification of the United Nations Convention on the Rights of the Child in 1995, significant efforts were made in Turkey to improve protection of children from abuse and neglect. The government took steps to amend relevant laws. Several state departments recognized the need for professional in-service training of relevant governmental agency staff. University hospitals established numerous hospital-based multidisciplinary child protection centres. The government established an Interministerial Higher Council, which has been overseeing the foundation of 13 child advocacy centres for a multidisciplinary and interagency response to child sexual abuse. In addition to undertaking research, non-governmental organizations contributed to this process by instituting professional and public education. These ground-breaking developments in the last decade give promise of even further improvement in the national child protection system from investigative, child protective and rehabilitative perspectives.

    Objective To observe the antileukemic effect in relapse patients by infusion of donor immunocompetent cells with or without granulocyte colony-stimulating factor (G-CSF) mobilization.Methods Twenty patients with leukemia in relapse after allogeneic bone marrow transplantation (allo-BMT) were treated with chemotherapy followed by donor-derived lymphocytes (DDL) without G-CSF mobilization (Group A, n=11), or donor peripheral blood progenitor cells (PBPCs) with G-CSF mobilization (Group B, n=9).Results Five patients in Group A were in hematologic relapse. After DDL infusion, 3 of 5 patients had a temporary complete remission (CR) and relapsed after 3, 7 and 10 months, respectively. One achieved partial remission and died of interstitial pneumonia; and the other one showed no response. Another 6 patients in Group A were in cytogenetic relapse or central nerve system (CNS) leukemia, and all achieved CR and remained in disease free survival (DFS) for 10 to 98 months after DDL infusion. All 9 patients in group B were in hematologic relapse. Three patients with chronic myeloid leukemia (CML) had cytogenetic and molecular remission for 16, 35 and 51 months, respectively after PBPC infusion; and 5 patients with acute lymphoid leukemia (ALL) had CR and were still in CR for 10 to 18 months except 1 patient relapsed soon. And the other one with AML showed no response to the therapy.Conclusion Donor immunocompetent cells infusion is an effective therapy for relapsed leukemia after allo-BMT, especially for the patients with early (molecular and cytogenetic) or CNS relapse. Infusion of donor PBPC mobilized by G-CSF seems to have more potentiated graft-versus-leukemia (GVL) effect than DDL infusion.

  14. Sensitivity improvement of an electrical sensor achieved by control of biomolecules based on the negative dielectrophoretic force.

    Effective control of nano-scale biomolecules can enhance the sensitivity and limit of detection of an interdigitated microelectrode (IME) sensor. Manipulation of the biomolecules by dielectrophoresis (DEP), especially the negative DEP (nDEP) force, so that they are trapped between electrodes (sensing regions) was predicted to increase the binding efficiency of the antibody and target molecules, leading to a more effective reaction. To prove this concept, amyloid beta 42 (Aβ42) and prostate specific antigen (PSA) protein were respectively trapped between the sensing region owing to the nDEP force under 5V and 0.05V, which was verified with COMSOL simulation. Using the simulation value, the resistance change (ΔR/Rb) of the IME sensor from the specific antibody-antigen reaction of the two biomolecules and the change in fluorescence intensity were compared in the reference (pDEP) and nDEP conditions. The ΔR/Rb value improved by about 2-fold and 1.66-fold with nDEP compared to the reference condition with various protein concentrations, and these increases were confirmed with fluorescence imaging. Overall, nDEP enhanced the detection sensitivity for Aβ42 and PSA by 128% and 258%, respectively, and the limit of detection improved by up to 2-orders of magnitude. These results prove that DEP can improve the biosensor's performance. PMID:27449966

    2016-05-01

    Using a quasi-experimental design, the effects of a student support intervention were estimated for the math and reading achievement of first-generation immigrant children (n = 667, M = 11.05 years of age) attending high-poverty, urban elementary schools. The intervention was designed to help schools identify developmental strengths and barriers to learning and, in turn, connect children to community and school supports aligned with their strengths and needs. By exploiting within-school changes in the implementation of the intervention, the present study revealed statistically and practically significant treatment effects indicating improvements in math and reading achievement at the end of elementary school. In addition, the intervention appears to considerably narrow achievement gaps between English language learners and immigrant children proficient in English. PMID:27028490

    Low ART-adherence amongst adolescents is associated with morbidity, mortality and onward HIV transmission. Reviews find no effective adolescent adherence-promoting interventions. Social protection has demonstrated benefits for adolescents, and could potentially improve ART-adherence. This study examines associations of 10 social protection provisions with adherence in a large community-based sample of HIV-positive adolescents. All 10-19-year-olds ever ART-initiated in 53 government healthcare facilities in a health district of South Africa's Eastern Cape were traced and interviewed in 2014-2015 (n = 1175 eligible). About 90% of the eligible sample was included (n = 1059). Social protection provisions were "cash/cash in kind": government cash transfers, food security, school fees/materials, school feeding, clothing; and "care": HIV support group, sports groups, choir/art groups, positive parenting and parental supervision/monitoring. Analyses used multivariate regression, interaction and marginal effects models in SPSS and STATA, controlling for socio-demographic, HIV and healthcare-related covariates. Findings showed 36% self-reported past-week ART non-adherence (75 copies/ml) (aOR 1.98, CI 1.1-3.45). Independent of covariates, three social protection provisions were associated with reduced non-adherence: food provision (aOR .57, CI .42-.76, p benefits. With no social protection, non-adherence was 54%, with any one protection 39-41%, with any two social protections, 27-28% and with all three social protections, 18%. These results demonstrate that social protection provisions, particularly combinations of "cash plus care", may improve adolescent adherence. Through this they have potential to improve survival and wellbeing, to prevent HIV transmission, and to advance treatment equity for HIV-positive adolescents. PMID:27392002

    2016-01-01

    Introduction To evaluate the impact of continuous positive airway pressure (CPAP) therapy on overactive bladder (OAB) symptoms in women with obstructive sleep apnea syndrome (OSAS). Material and methods One-hundred and fifty women underwent an overnight polysomnography study between May 2014 and September 2014. Their voiding symptoms were evaluated using the OAB symptom score (OABSS) and International Consultation on Incontinence Questionnaire Short-Form at OSAS diagnosis and approximately 3-months after CPAP therapy. OSAS severity was assessed according to the apnea-hypopnea-index. Results We evaluated 140 women and 111 of them (79.3%) reported symptoms consistent with OAB. There were no statistically significant differences between OSAS severity with a prevalence of OAB (p = 0.92). The prevalence of urinary incontinence (UI) was 35.7% (n = 50) and 39.6% (n = 44) in all patients and patients with OAB, respectively. There were no statistically significant differences between UI with OAB (p = 0.58). Baseline OABSS is comparable between OSAS severity (p = 0.143). After 3-months CPAP therapy, OABSS and ICIQ-SF sum scores were significantly decreased in patients with severe and moderate OSAS (p <0.01), however, change of OABSS sum score was insignificant in patients with mild OSAS (p = 0.44). Conclusions CPAP therapy improves the OAB, OABSS and ICIQ-SF scores in women with severe and moderate OSAS. OSAS-induced OAB may be alleviated following CPAP therapy. PMID:27123331

  20. Beyond Effectiveness: A Pragmatic Evaluation Framework for Learning and Continuous Quality Improvement of e-Learning Interventions in Healthcare.

    Dafalla, Tarig Dafalla Mohamed; Kushniruk, Andre W; Borycki, Elizabeth M

    2015-01-01

    A pragmatic evaluation framework for evaluating the usability and usefulness of an e-learning intervention for a patient clinical information scheduling system is presented in this paper. The framework was conceptualized based on two different but related concepts (usability and usefulness) and selection of appropriate and valid methods of data collection and analysis that included: (1) Low-Cost Rapid Usability Engineering (LCRUE), (2) Cognitive Task Analysis (CTA), (3) Heuristic Evaluation (HE) criteria for web-based learning, and (4) Software Usability Measurement Inventory (SUMI). The results of the analysis showed some areas where usability that were related to General Interface Usability (GIU), instructional design and content was problematic; some of which might account for the poorly rated aspects of usability when subjectively measured. This paper shows that using a pragmatic framework can be a useful way, not only for measuring the usability and usefulness, but also for providing a practical objective evidences for learning and continuous quality improvement of e-learning systems. The findings should be of interest to educators, developers, designers, researchers, and usability practitioners involved in the development of e-learning systems in healthcare. This framework could be an appropriate method for assessing the usability, usefulness and safety of health information systems both in the laboratory and in the clinical context. PMID:25676959

  1. Investigations of Techniques to Improve Continuous Air Monitors Under Conditions of High Dust Loading in Environmental Settings

    A number of DOE facilities, such as the Los Alamos National Laboratory (LANL) and the Waste Isolation Pilot Plant (WIPP), use alpha-particle environmental continuous air monitors (ECAMs) to monitor air for unwanted releases of radioactive aerosols containing such materials as plutonium and uranium. High sensitivity, ease of operation, and lack of false alarms are all important for ECAMs. The object of the project was to conduct investigations to improve operation of ECAMs, particularly under conditions where a lot of nonradioactive dust may be deposited on the filters (conditions of high dust loading). The presence of such dust may increase the frequency with which filters must be changed and can lead to an increased incidence of false alarms due to deteriorated energy resolution and response specificity to the radionuclides of interest. A major finding of the investigation, not previously documented, was that under many conditions thick layers of underlying nonradioactive dust do not decrease energy resolution and specificity for target radionuclides if the radioactive aerosol arrives as a sudden thin burst deposit, as commonly occurs in the early-warning alarm mode. As a result, operators of ECAMs may not need to change filters as often as previously thought and have data upon which to base more reliable operating procedures

  2. Experiences in the continuous improvement of quality assurance of the dosimetry services of SLDC-MD-ININ

    From 2003 the Secondary Laboratory of Dosimetric Calibration (SLDC) of Metrology Department of Ionizing Radiations (MD), has complemented the Quality Manual of National Institute of Nuclear Research (ININ) according to the standard ISO 9001: 2000. However, due to that the National Center of Metrology of Mexico delegates its functions in the dosimetry and activity area for the field of the ionizing radiations to the ININ: one of the requirements so that the ININ has been designated as -Declared Institute- before the International Office of Weights and Measurements, it is to demonstrate before the Inter-American System of Metrology that the quality system of the SLDC fulfills the standard ISO/IEC 17025: 2005, satisfied this requirement the Inter-American System of Metrology in their meeting of evaluation of quality systems, Ottawa (2007) grants a certification document to the SLDC that guarantees their capacities of calibration measurements for dosimetry services. Concretely, inside the standard activities ISO 9000 with respect to the point 8 on measurement, analysis and improvement the Management of Quality Assurance of ININ carries out at year two interns auditing and every month is given continuation to the non conformities detected in the procedures that support the services of the SLDC for dosimetry with purposes of radiological protection and clinical dosimetry.

    2015-04-01

    Full Text Available Background: Recruitment maneuvers are often used in critical care patients with hypoxemic respiratory failure. Although continuous positive airway pressure/pressure support (CPAP/PS ventilation is a frequently used approach, but whether lung recruitment also improves oxygenation in spontaneously breathing patients has not been investigated yet. The primary objective was to analyse the effect of recruitment maneuver on oxygenation in patients ventilated in CPAP/PS mode. Methods: Following baseline measurements PEEP was increased by 5 cmH2O. Recruitment maneuver was applied for 40 seconds with 40 cmH2O of PS. Measurements of the difference in PaO2/FiO2 and airway parameters measured by the ventilator were recorded immediately after recruitment then 15 and 30 minutes later. Thirty patients ventilated in CPAP/PS mode with a PEEP ≥ 5 cmH2O were enrolled in this prospective, observational study if their PaO2/FiO2 ratio was 0.5. Results: Following recruitment maneuver patients were considered as non-responders (NR, n=15 if difference of PaO2/FiO2 < 20 % and responders (R, n=15 if difference of PaO2/FiO2 ≥ 20 %. In the NR-group PaO2/FiO2 decreased non-significantly from baseline: median [interquartile], PaO2/FiO2 = 176 [120-186] vs. after recruitment: 169 [121-182] mmHg, P = .307 while in the R-group there was significant improvement: 139 [117-164] vs. 230 [211-323] mmHg, P = .01. At the same time points dead space to tidal volume ratio (Vds/Vte significantly increased in the NR-group Vds/Vte = 32 [27-37] vs. 36 [25-42] %, P = .013 but no significant change was observed in the R-group: 26 [22-34] vs. 27 [24-33] %, p = .386.Conclusion: Recruitment maneuver improved PaO2/FiO2 ratio by ≥ 20 % in 50 % of patients ventilated in CPAP/PS mode.

  6. The introduction of the personnel dosimetry information system in Greece designed as a relational database and the improvements achieved

    Dose record keeping is the making and keeping of personnel dose records for radiation workers. It is an essential part of the process of monitoring the exposure of individuals to radiation and shares in the same objectives. The dose record keeping is becoming more and more critical because of the importance of statistical analysis and epidemiological studies in radiation protection, and of the increasing cooperation and exchange of personnel between countries.The GAEC's personnel dosimetry laboratory assures the personnel dosimetry all over the country and keeps the official central dose record.The personnel dosimetry information system had been established in an electronic form on 1989 in Cobol language. Since then appeared various arguments that imposed the change of the data base used. Some of them are: 1. There was no distinction between establishments and their laboratories. 2. The workers did not have a unique code number. consequently, the total dose of a person working in more than one place could not't be estimated. The workers were directly related to their workplace, so if somebody changed his working place he was treated as a new entry, resulting an overestimation of the number of monitored workers introducing an source of errors in the collective and average dose calculations. 3. With the increasing applications of the ionising radiations many types of dosemeters became indispensable e.g. for beta and gamma, for neutrons and for the extremities. Also, the new category of outside workers appeared requesting a special treatment. All these distinctions were not achievable with the previous system. 4. Last years appeared an increasing, interesting in statistical analysis of the personal doses. A program written in Cobol does not't offer many possibilities and has no flexibility for such analysis. The new information system has been rebuilt under the design of a relational database with more possibilities and more flexibility. (authors)

  8. General chemistry courses that can affect achievement: An action research study in developing a plan to improve undergraduate chemistry courses

    Shweikeh, Eman

    Over the past 50 years, considerable research has been dedicated to chemistry education. In evaluating principal chemistry courses in higher education, educators have noted the learning process for first-year general chemistry courses may be challenging. The current study investigated perceptions of faculty, students and administrators on chemistry education at three institutions in Southern California. Via action research, the study sought to develop a plan to improve student engagement in general chemistry courses. A mixed method was utilized to analyze different perceptions on key factors determining the level of commitment and engagement in general chemistry education. The approach to chemistry learning from both a faculty and student perspective was examined including good practices, experiences and extent of active participation. The research study considered well-known measures of effective education with an emphasis on two key components: educational practices and student behavior. Institutional culture was inclusively assessed where cognitive expectations of chemistry teaching and learning were communicated. First, the extent in which faculty members are utilizing the "Seven Principles for Good Practice in Undergraduate Education" in their instruction was explored. Second, student attitudes and approaches toward chemistry learning were examined. The focus was on investigating student understanding of the learning process and the structure of chemistry knowledge. The seven categories used to measure students' expectations for learning chemistry were: effort, concepts, math link, reality link, outcome, laboratory, and visualization. This analysis represents the views of 16 faculty and 140 students. The results validated the assertion that students need some competencies and skills to tackle the challenges of the chemistry learning process to deeply engage in learning. A mismatch exists between the expectations of students and those of the faculty

  9. Achievements of grain legume variety improvement using induced mutation of the IAEA/RAS/5/040 project in Thailand

    The project aims to form a regional cooperation network of mutation germplasm with emphasis on seed-propagated crops among the member states in Asia and Pacific during 2002-2006. It comprised of two components: the establishment and implementation of mutant multi-location trials and the establishment of mutation germplasm network. Thailand participated two crops, soybean and mungbean, of both components. Significant achievements are summarized. Soybean mutant multi-location trials: two introduced mutants were well adapted in the upper and lower north of Thailand. DT84 from Vietnam produced similar yield and matured 18 days earlier than Chiang Mai 60. Bangsakong from Korea gave 11% greater yield with 12 days earlier than Sukhothai 2. Soybean mutants resistant to Soybean Crinkle Leaf: the disease caused by virus and transmitted by whitefly is a major disease in Thailand. Seed of line CM9238-54-1(ST) was irradiated with 200 gray. Mutant lines were selected under natural field infections and tested in laboratory. Six mutant lines resistant to the disease were finally selected. Soybean mutants with high grain protein: seed of vars Chiang Mai 60, SSRSN19-35-4 and EHP275 was irradiated with 200 gray. Pedigree method of selection was used and grain protein of mutants was analysed. The results of a preliminary trial showed that 32 selected mutant lines gave 0.8, 2.0 and 1.0% higher grain protein than the original parents of 41.8, 40.3 and 41.9%, respectively. Soybean mutants with high seed germination and vigor: seed of Chiang Mai 60, a high yielding variety with poor seed germination and vigor, was irradiated with 100 gray. Pedigree selection method was used in late generations. Accelerated Aging Test was also used to test the seed vigor of the mutant lines. In dry season trial, eight mutant lines had seed germination of 65-75% compared with the parent of 30%. In rainy season, 12 mutant lines had seed germination of 75-89% whereas the parent had only 41%. Mungbean mutant

  10. Enhancement of filterability in MBR achieved by improvement of supernatant and floc characteristics via filter aids addition.

    Ji, Jing; Qiu, Jiangping; Wong, Fook-sin; Li, Yaozhong

    2008-08-01

    Reduction of membrane fouling in membrane bioreactors (MBR) by addition of three typical filter aids (aluminum sulfate (Al(2)(SO(4))(3)), polymeric ferric sulfate (PFS) and Chitosan) was investigated. The effects of filter aids on membrane pore blocking, gel layer and cake layer resistance were analyzed respectively. Significant improvement of the sustainable filtration was demonstrated in the filter aids added MBRs. The membrane fouling rate of the MBRs operated under 20L/m(2)h flux was in the order of Control MBR (no filter aid added)>Al(2)(SO(4))(3) added MBR>Chitosan added MBR>PFS added MBR. Membrane inner fouling due to pore blocking was analyzed by means of Fourier-transform infrared microscope (FTIR). Compared to the control MBR, significantly low protein and carbohydrate concentrations were measured in the membranes of the filter aids added MBRs, indicating that filter aids could effectively alleviate membrane pore blocking. Gel Permeation Chromatography (GPC) analysis suggested that both the concentration and molecular weight distribution of the macromolecules in supernatant play an important role in gel layer formation and loss of membrane porosity. The reduction of fouling rate in the filter aids added MBRs could be attributed to lower concentration and reduction in molecular weight of macromolecules in supernatant. The specific cake resistance (alpha(c)), mean floc size (d(p)) and fractal dimension of the flocs (df) in the filter aids added MBRs were also investigated. It was demonstrated that alpha(c) decreased with the increase of d(p) and with the decrease of df, which is in consistent with the model prediction. PMID:18694586

  11. Topical issues in nuclear installation safety: Continuous improvement of nuclear safety in a changing world. Proceedings of an international conference

    In 1991, the IAEA organized an International Conference on the Safety of Nuclear Power: Strategy for the Future. Recommendations from that conference prompted actions in subsequent installations worldwide, and included the establishment of the Convention on Nuclear Safety, which entered into force in October 1996. In 1998, the IAEA sponsored an International Conference on Topical Issues in Nuclear, Radiation and Radioactive Waste Safety. In response to the concerns identified and the recommendations provided by the conference, actions were taken to improve the monitoring of safety by developing performance indicators; furthering the use of probabilistic safety insights to complement and help optimize the prescriptive nature of regulations; and addressing actions needed to ensure the future availability of competent professionals. In 2001, the IAEA sponsored an International Conference on Topical Issues in Nuclear Safety. The findings were again essential in providing Member States, the IAEA and the nuclear industry with insights into where future activities should be focused. Some of these areas included the need to develop international guidance on the use of probabilistic safety insights, the potential negative impacts on safety from external factors, the need for emergency preparedness guidance for fuel cycle facilities, the safety challenges associated with poor utilization programmes at research reactors, and the need to develop simple indicators of safe operating performance. Although substantial progress has been made in improving the safe operational performance of nuclear installations over the past years, numerous issues continue to be of concern. These include ensuring quality of design and operation of nuclear installations with the growing diversification and globalization of the nuclear community, obtaining, maintaining and managing knowledge, utilizing common internationally accepted safety standards, balancing the needs between safety and security

    This study aimed to investigate the effects of two periodized training programs of deep water running on functional fitness and blood pressure in the older adults. Thirty-six individuals were divided into continuous group (CONT) and interval group (INT). Both groups were trained for 28 weeks (twice weekly). Measures were performed before the training period, after 12 weeks and training period. Two-way ANOVA and post hoc of Bonferroni were used (α = 0.05). There were no differences between groups in functional tests, with the exception of the flexibility of the upper limbs, in which the INT group showed the highest values. There was a significant improvement in both groups of foot up-and-go test (CONT 6.45 to 5.67; INT 6.59 to 5.78, in seconds), flexibility of lower limbs (CONT -4.76 to -0.61; INT 0.54 to 4.63, in centimeters), strength of upper (CONT 18.76 to 27.69; INT 18.66 to 26.58, in repetitions) and lower limbs (CONT 14.46 to 21.23; INT 14.40 to 21.58, in repetitions), and 6-min walk (CONT 567.50 to 591.16; INT 521.41 to 582.77, in meters). No differences were shown between groups for systolic blood pressure; however, diastolic blood pressure remained higher in CONT during all training. The blood pressure decreased significantly in both groups after the training (CONT 142 ± 16/88 ± 3 to 125 ± 14/77 ± 7 mmHg; INT 133 ± 15/75 ± 7 to 123 ± 17 and 69 ± 11 mmHg). Both programs of deep water running training promoted improvements of similar magnitude in all parameters of functional fitness, with the exception of flexibility of upper limbs, and decreased blood pressure in the older individuals.

    2016-01-01

    We evaluated temporal trends in survival of Swedish acute myeloid leukemia (AML) patients diagnosed between 1973 and 2011 using relative survival ratios (RSRs) and a measure called the loss in expectation of life (LEL). RSRs increased most for patients <60 years at diagnosis during the first calendar periods, but between 1997-2005 and 2006-2011 the most pronounced increase was for those aged 61-70 years at diagnosis; RSR changed from 0.16 (95% confidence interval (CI): 0.13-0.19) to 0.28 (95% CI: 0.23-0.33), respectively. The LEL for males aged 35 years at diagnosis was 41.0 (95% CI: 40.1-41.8) years in 1975 and 19.5 (95% CI: 16.4-22.5) years in 2011. For males aged 65 years, the corresponding figures were 13.8 (95% CI: 13.7-14.0) and 12.0 (95% CI: 11.3-12.8). Conditional LEL estimates suggested that patients who survive 5 years postdiagnosis have shorter remaining lifespan than the general population. The proportion of expected life lost (PELL) suggested that male 65-year-old patients lost 75% of their life expectancy in 2005 and 66% if they were diagnosed in 2011. Survival continued to increase to 2011, with larger improvements in those aged 61-70 years at diagnosis. The LEL and PELL are intuitive measures that may be useful in communicating survival statistics to patients, clinicians and health-care providers. PMID:26849011

    IAEA/RAS/5/040 project aims to form a regional cooperation network of mutation germplasm with emphasis on seed-propagated crops among the Member States in Asia and Pacific commencing in 2002 and ending in 2006. It comprised of two components, the establishment and implementation of mutant multi-location trials and the establishment of mutation germplasm network. Thailand participated with two major grain legume crops, soybean and mungbean, of both components. Significant achievements are summarized. Soybean mutant multi-location trials: Two introduced mutants, DT84 from Vietnam and Bangsakong from Korea were well adapted in the upper and lower north of Thailand. DT84 produced similar yield and matured 18 days earlier than Chiang Mai 60 whereas Bangsakong gave 11% greater yield with 12 days earlier than Sukhothai. Soybean mutants resistant to Soybean Crinkle Leaf: The disease, caused by virus, is a major disease in Thailand. It is transmitted by whitefly (Bemisia tabaci). Seed of a soybean linecm9238-54-1(ST) was irradiated with 200 gray. A number of mutant lines were selected under natural field infections and tested in laboratory. Six mutant lines resistant to the disease were finally selected. Soybean mutants with high grain protein: The government policy is to increase grain protein soybean for soy food products. Seeds of three soybean varieties namely Chiang Mai 60, SSRSN19-35-4 and EHP275 were irradiated with 200 gray. Pedigree method of selection was used and grain protein of the mutants was analysed. Thirty two mutant lines were selected. The result of a preliminary trial showed that the lines gave average grain protein of 0.8, 2.0 and 1.0% higher than the original parents of 41.8, 40.3 and 41.9%, respectively. Soybean mutants with high seed germination and vigor: Chiang Mai 60, a high yielding soybean variety, has a poor character of seed germination and vigor. Seed of Chiang Mai 60 was irradiated with 100 gray. Pedigree method of selection was used in late

  16. Longitudinal Numbers-Needed-To-Treat (NNT for Achieving Various Levels of Analgesic Response and Improvement with Etoricoxib, Naproxen, and Placebo in Ankylosing Spondylitis

    Wang Hongwei

    2011-07-01

    Full Text Available Abstract Background Clinical analgesic trials typically report response as group mean results. However, research has shown that few patients are average and most have responses at the extremes. Moreover, group mean results do not convey response levels and thus have limited value in representing the benefit-risk at an individual level. Responder analyses and numbers-needed-to-treat (NNT are considered more relevant for evaluating treatment response. We evaluated levels of analgesic response and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI score improvement and the associated NNTs. Methods This was a post-hoc analysis of a 6-week, randomized, double-blind study (N = 387 comparing etoricoxib 90 mg, etoricoxib 120 mg, naproxen 1000 mg, and placebo in AS. Spine pain and BASDAI were measured on a 100-mm visual analog scale. The number and percentage of patients achieving ≥30% and ≥50% improvement in both BASDAI and spine pain were calculated and used to determine the corresponding NNTs. Patients who discontinued from the study for any reason were assigned zero improvement beyond 7 days of the time of discontinuation. Results For etoricoxib 90 mg, etoricoxib 120 mg and naproxen 1000 mg, the NNTs at 6 weeks compared with placebo were 2.0, 2.0, and 2.7 respectively for BASDAI ≥30% improvement, and 3.2, 2.8, and 4.1 for ≥50% improvement. For spine pain, the NNTs were 1.9, 2.0, and 3.2, respectively, for ≥30% improvement, and 2.7, 2.5, and 3.7 for ≥50% improvement. The differences between etoricoxib and naproxen exceeded the limit of ±0.5 units described as a clinically meaningful difference for pain. Response rates and NNTs were generally similar and stable over 2, 4, and 6 weeks. Conclusions For every 2 patients treated with etoricoxib, 1 achieved a clinically meaningful (≥30% improvement in spine pain and BASDAI beyond that expected from placebo, whereas the corresponding values were approximately 1 in every 3 patients

  18. The Power to drive change: Working together for excellence. Creating a continuously improving consumer engagement framework for excellence in patient-centered care.

    Ryan, Catherine

    2016-01-01

    The World Health Organization has acknowledged Patient Safety while receiving hospital care as a serious global public health issue, with patient empowerment and community engagement key to continuously improving safety and quality of care for the best possible clinical and patient outcomes. In Australia, the introduction of ten mandatory National Safety and Quality Health Service Standards in 2011 provided the catalyst for all Australian health facilities to review their systems. Standard 2: Partnering with Consumers required health facilities across Australia to assess commitment to, and capacity for consumer and community engagement and participation. At this time, the Royal Brisbane and Women's Hospital did not have a strategic perspective and understanding, or an organizational structure for engaging with consumers (patients, families, care givers and community members). The concept required a new model to replace the clinician-led model of healthcare historically featured in Australia, with a change in culture and core business. processes to partner with consumers at all levels of the system, from individual patient care through to participating in policy development, health service planning and delivery, and evaluation and measurement processes. The challenge for the hospital was to build a sustainable framework of engagement for a genuine patient-centered model of care informed by best practice, and provide leadership and commitment to developing as an area of excellence in patient engagement and experience. A successful and sustainable framework for consumer and community engagement has been embedded in the hospital, with resultant culture change, achieving accreditation across all core and developmental criteria for the partnering with consumer standards including several Met with Merit ratings.

    Full Text Available Some sophisticated medical applications, including advanced therapeutics with monoclonal antibodies, stem cells, and gene therapies are currently available in clinical trials. More revolutionary technologies are coming soon and will be marketed by the best technically advanced companies in the world. R&D companies with a much smaller indicator of technological progress and organizational efficiency, but with a great desire to become a major player in this industry, will also compete for a share of this market. However, in order to become a fixture in the changes initiated, both must constantly learn and be more innovative. In the current market situation, a hypercompetitive economy with the entrepreneurs’ focus on the prosumer, creativity is becoming extremely important in achieving final success. Creativity, which is the result of proper knowledge management, especially in science. The market value of R&D companies and their further future depends to a large extent on the prosperity of knowledge transfer. The most important role in the process of knowledge transfer is played by information and communication technologies (ICT and tools for continuous improvement. If companies implement these efficiently and safely, they can develop and benefit from competitive advantages for a very long period of time. Such an approach would give them the possibility of reducing the cost and time to deliver new products to market, and create a new platform to generate innovative products. This is a new perspective for R&D businesses, and a great opportunity for institutions in the biomedical arena to become part of the upcoming bio-revolution.

  3. Effectiveness of music education for the improvement of reading skills and academic achievement in young poor readers: a pragmatic cluster-randomized, controlled clinical trial.

    Hugo Cogo-Moreira

    Full Text Available INTRODUCTION: Difficulties in word-level reading skills are prevalent in Brazilian schools and may deter children from gaining the knowledge obtained through reading and academic achievement. Music education has emerged as a potential method to improve reading skills because due to a common neurobiological substratum. OBJECTIVE: To evaluate the effectiveness of music education for the improvement of reading skills and academic achievement among children (eight to 10 years of age with reading difficulties. METHOD: 235 children with reading difficulties in 10 schools participated in a five-month, randomized clinical trial in cluster (RCT in an impoverished zone within the city of São Paulo to test the effects of music education intervention while assessing reading skills and academic achievement during the school year. Five schools were chosen randomly to incorporate music classes (n = 114, and five served as controls (n = 121. Two different methods of analysis were used to evaluate the effectiveness of the intervention: The standard method was intention-to-treat (ITT, and the other was the Complier Average Causal Effect (CACE estimation method, which took compliance status into account. RESULTS: The ITT analyses were not very promising; only one marginal effect existed for the rate of correct real words read per minute. Indeed, considering ITT, improvements were observed in the secondary outcomes (slope of Portuguese = 0.21 [p<0.001] and slope of math = 0.25 [p<0.001]. As for CACE estimation (i.e., complier children versus non-complier children, more promising effects were observed in terms of the rate of correct words read per minute [β = 13.98, p<0.001] and phonological awareness [β = 19.72, p<0.001] as well as secondary outcomes (academic achievement in Portuguese [β = 0.77, p<0.0001] and math [β = 0.49, p<0.001] throughout the school year. CONCLUSION: The results may be seen as promising, but they are not

  4. Using optimal combination of teaching-learning methods (open book assignment and group tutorials) as revision exercises to improve learning outcome in low achievers in biochemistry.

    Rajappa, Medha; Bobby, Zachariah; Nandeesha, H; Suryapriya, R; Ragul, Anithasri; Yuvaraj, B; Revathy, G; Priyadarssini, M

    2016-07-01

    Graduate medical students of India are taught Biochemistry by didactic lectures and they hardly get any opportunity to clarify their doubts and reinforce the concepts which they learn in these lectures. We used a combination of teaching-learning (T-L) methods (open book assignment followed by group tutorials) to study their efficacy in improving the learning outcome. About 143 graduate medical students were classified into low (75%: group 3, n = 46) achievers, based on their internal assessment marks. After the regular teaching module on the topics "Vitamins and Enzymology", all the students attempted an open book assignment without peer consultation. Then all the students participated in group tutorials. The effects on the groups were evaluated by pre and posttests at the end of each phase, with the same set of MCQs. Gain from group tutorials and overall gain was significantly higher in the low achievers, compared to other groups. High and medium achievers obtained more gain from open book assignment, than group tutorials. The overall gain was significantly higher than the gain obtained from open book assignment or group tutorials, in all three groups. All the three groups retained the gain even after 1 week of the exercise. Hence, optimal use of novel T-L methods (open book assignment followed by group tutorials) as revision exercises help in strengthening concepts in Biochemistry in this oft neglected group of low achievers in graduate medical education. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(4):321-325, 2016.

  5. Impacts of continual and periodic disturbances on a Central Amazonian forest: lessons from a gap model for future model improvement

    Holm, J. A.; Chambers, J. Q.; Collins, W.

    2013-12-01

    Uncertainties surrounding vegetation and carbon responses to increased disturbance rates associated with climate change remains a major global change issue for Amazon forests. To help quantify the impacts of increased disturbances on climate and the earth system, the fidelity of tree mortality and disturbance algorithms in global land surface models (here the Community Land Model, CLM) warrant critical evaluation. In order to address this issue, we parameterized and calibrated ZELIG-TROP, a dynamic vegetation gap model, to simulate a complex Central Amazon forest toward improving disturbance-recovery processes in CLM. To evaluate the long-term consequences of increased disturbance rates in ZELIG-TROP and CLM for a Central Amazon rainforest, we 1) doubled background tree mortality rates (i.e., high disturbance treatment), and 2) applied a periodic disturbance treatment of removing 20% of stems every 50 years (i.e., periodic treatment) and compared model results. For the high disturbance treatment, ZELIG-TROP predicted that AGB and ANPP decreased by an average of 110 Mg ha-1 and 0.48 Mg C ha-1 yr-1 respectively (41.9% and 7.7%). The net carbon loss due to the periodic treatment, with four large-scale disturbances, was not as extreme as the loss from the high disturbance treatment, due to recovery dynamics. AGB only decreased by 15.9% (vs. 41.9%), however ANPP decreased by 19% (vs. 7.7%). For the high disturbance treatment in ZELIG-TROP, there were a higher proportion of smaller stems and a decrease in larger stems. This resulted in a decrease in coarse litter (trunks and large branches >10 cm in diameter) production rates (Mg C ha-1 yr-1) by 11.5%. For the periodic disturbance the average coarse litter production rates increased by 11.2% due to the four large-scale disturbance events. A comparison of the biomass response of ZELIG-TROP and CLM from simulated disturbance and recovery events displayed the same pattern between the two models, and for both disturbance

  11. Continuous parallel coordinates.

    Heinrich, Julian; Weiskopf, Daniel

    2009-01-01

    Typical scientific data is represented on a grid with appropriate interpolation or approximation schemes,defined on a continuous domain. The visualization of such data in parallel coordinates may reveal patterns latently contained in the data and thus can improve the understanding of multidimensional relations. In this paper, we adopt the concept of continuous scatterplots for the visualization of spatially continuous input data to derive a density model for parallel coordinates. Based on the point-line duality between scatterplots and parallel coordinates, we propose a mathematical model that maps density from a continuous scatterplot to parallel coordinates and present different algorithms for both numerical and analytical computation of the resulting density field. In addition, we show how the 2-D model can be used to successively construct continuous parallel coordinates with an arbitrary number of dimensions. Since continuous parallel coordinates interpolate data values within grid cells, a scalable and dense visualization is achieved, which will be demonstrated for typical multi-variate scientific data.

    Principles for Excellence in Human Performance should promote behaviors throughout an organization that support safety and reliable operation of the plant. Such behaviors must be clearly defined, communicated and reinforced by managers, on a continuous basis. To identify if workers behaviors are in compliance with those expected is paramount to have an observations program in place, which in one hand identifies deviations from expectations to correct them, and on the other promotes the desired behaviors through positive reinforcement.

  19. Improving the maximum transmission distance of continuous-variable quantum key distribution with noisy coherent states using a noiseless amplifier

    By employing a nondeterministic noiseless linear amplifier, we propose to increase the maximum transmission distance of continuous-variable quantum key distribution with noisy coherent states. With the covariance matrix transformation, the expression of secret key rate under reverse reconciliation is derived against collective entangling cloner attacks. We show that the noiseless linear amplifier can compensate the detrimental effect of the preparation noise with an enhancement of the maximum transmission distance and the noise resistance. - Highlights: • Noiseless amplifier is applied in noisy coherent state quantum key distribution. • Negative effect of preparation noise is compensated by noiseless amplification. • Maximum transmission distance and noise resistance are both enhanced

  20. Improving the teaching and learning of science in a suburban junior high school on Long Island: Achieving parity through cogenerative dialogues

    Baker, Eileen Perman

    The research in this dissertation focuses on ways to improve the teaching and learning of science in a suburban junior high school on Long Island, New York. The study is my attempt to find ways to achieve parity in my classroom in terms of success in science. I was specifically looking for ways to encourage Black female students in my classroom and in other classrooms to continue their science education into the upper grades. The participants were the 27 students in the class, a friend of one of the students, and I, as the teacher-researcher. In order to examine the ways in which structure mediates the social and historical contexts of experiences in relation to teacher and student practices in the classroom, I used collaborative research; autobiographical reflection; the sociology of emotions; immigration, racialization, and ethnicity, and cogenerative dialogues (cogens) as tools. Cogenerative dialogues are a way for students and teachers to accept shared responsibility for teaching and learning. This study is of importance because of my school's very diverse student body. The school has a large minority population and therefore shares many of the characteristics of urban schools. In my study I look at why there are so few Black female students in the advanced science courses offered by our district and how this problem can be addressed. I used a variety of qualitative approaches including critical ethnography and micro analysis to study the teaching and learning of science. In addition to the usual observational, methodological, and theoretical field notes, I videotaped and audiotaped lessons and had discussions with students and teachers, one-on-one and in groups. In the first year the cogenerative group consisted of two Black female students. In the second year of the study there were four Black and one White-Hispanic female students in the cogen group. In my research I studied the interactions of the students between lessons and during laboratory activities as

  1. Client incentives versus contracting and staff incentives: how care continuity interventions in substance abuse treatment can improve residential to outpatient transition.

    Acquavita, Shauna P; Stershic, Sandra; Sharma, Rajni; Stitzer, Maxine

    2013-07-01

    Interventions for improving transition from short-term residential to outpatient treatment were examined. Usual care (UC; n=114) was referral to a preferred outpatient program with advance appointment optional. Client incentive (CI; n=97) offered up to $100 in gift cards for intake and attendance during the first 30days of treatment. Contracting with staff incentives (CSI; n=49) consisted of meeting with an outpatient counselor prior to residential discharge, signing an attendance contract, receiving an appointment and payment to staff if clients attended. CSI significantly improved rates of successful transition (84%) and admission (74%) compared to UC (64% contact; 49% admitted). CI did not result in significantly improved outcomes (74%; 60%). CSI was likely mediated by the reliability (92 versus 52% in UC) and immediacy (1.0 versus 3.9days) of appointment scheduling. This study supports use of CSI for improving rates of transition between residential and outpatient continuing care treatment. PMID:23375361

    New-generation multi-mode 9xx mini-bars used in fiber pump modules have been developed. The epitaxial designs have been improved for lower fast-axis and slow-axis divergence, higher slope efficiency and PCE by optimizing layer structures as well as minimizing internal loss. For 915nm mini-bars with 5-mm cavity length, maximum PCE is as high as ~61% for 35W operation and remains above 59% at 45W. For 808nm, a PCE of 56% at 135W CW operation has been demonstrated with 36%-fill-factor, 3-mm-cavity-length, water-cooled bars at 50°C coolant temperature. On passive-cooled standard CS heatsinks, PCE of >51% is measured for 100W operation at 50°C heatsink temperature. Leveraging these improvements has enabled low-cost bars for high-power, high-temperature applications.

    1991-01-01

    AS-4/polyimidesulfone (PISO2) composite prepreg was utilized for the improved compression molding technology investigation. This improved technique employed molding stops which advantageously facilitate the escape of volatile by-products during the B-stage curing step, and effectively minimize the neutralization of the consolidating pressure by intimate interply fiber-fiber contact within the laminate in the subsequent molding cycle. Without the modifying the resin matrix properties, composite panels with both unidirectional and angled plies with outstanding C-scans and mechanical properties were successfully molded using moderate molding conditions, i.e., 660 F and 500 psi, using this technique. The size of the panels molded were up to 6.00 x 6.00 x 0.07 in. A consolidation theory was proposed for the understanding and advancement of the processing science. Processing parameters such as vacuum, pressure cycle design, prepreg quality, etc. were explored.

    Full Text Available There are number of obstacles on a challenging road to the effectiveness and business and organizational excellence. One of the most difficult ones is human (not understanding of the constant flux of change. Such is the case when it comes to development of quality management system. Will the quality be either a problem or resource of some organization depends above all on the basic standpoint towards quality that exists in the organization. Many authors underline that implementation of quality management system and obtaining ISO 9000 certificate is not an easy task, but also emphasize that its maintenance and improvement is much more difficult task. The greatest number of problems that occur during the realization of project of quality management system as well as its improvement are the result of misunderstanding of the essence of standard, that is its principles. On of these principles is Leadership too, that is the role of Top Management. Managers at the highest levels are certainly the most responsible for establishing the vision and guiding organization in all business aspects, including Quality Management and Quality Management System. This work presents results of research conducted on the top management in 204 organizations with introduced quality system. Results show views of top management about the effects of introduced quality system as well as about future steps in terms of improving the same.

  5. Continuous, high-resolution spatial mapping of water isotopes: improving tools for quantifying local evaporation and residence times

    Dennis, Kate J.; Carter, Jeffrey A.; Winkler, Renato; Downing, Brian; Kendall, Carol; Bergamaschi, Brian

    2015-04-01

    Stable isotopes of water (d2H, d18O) are unique tracers of many hydrological processes including evaporation, precipitation, reservoir mixing and residence time. Historically, discrete water samples have been collected and analyzed via either Isotope Ratio Mass Spectrometry, or more recently laser-based spectroscopic methods, such as Cavity Ring-Down Spectroscopy (CRDS). However, the analysis of discrete samples precludes the ability to construct high resolution water isotope data sets through time and space. By coupling a recently developed front-end peripheral device (Continuous Water Sampler or CWS) to a CRDS analyzer (Picarro L2130-i), we continuously measured and spatially mapped water isotopes on a transect of the Sacramento River Delta following an extended period of drought. More than two-thousand five-second average d18O and d2H measurements were made aboard the R/V King (USGS) over a six-hour period. In addition to water isotopes, nitrate, chlorophyll, dissolved organic matter (DOM) fluorescence, and other water quality parameters were also measured continuously. As you travel northeast up the delta, surface waters become progressively more enriched in 18O and 2H, while nitrate decreased in concentration and chlorophyll and DOM increased. We utilize the spatially-mapped isotope data within a single transect to understand local evaporation and residence time by (i) utilizing the secondary parameter, d-excess, and (ii) using a simple mass balance model of water moving through the system (inflow, outflow and evaporation). Additional transects, to be conducted during the rainy season, should highlight how the Delta system evolves seasonally. In concert with other data previously collected from the Sacramento River Delta, we suggest the lower region represents a mixture of river waters derived from the Sierra Nevada Mountains and the more marine waters from the mouth of the San Francisco Bay.

    When the systems needed to remove decay heat are inoperable or degraded, the risk of shutting down the plant may be comparable to, or even higher than, that of continuing power operation with the equipment inoperable while giving priority to repairs. This concern arises because the plant may not have sufficient capability for removing decay heat during the shutdown. However, Technical Specifications (TSs) often require {open_quotes}immediate{close_quotes} shutdown of the plant. In this paper, we present risk-based analyses of the various operational policy alternatives available in such situations, with an example application to the standby service water (SSW) system of a BWR. These analyses can be used to define risk-effective requirements for those standby safety systems under discussion.

    2013-01-01

    Glucose readings provided by current continuous glucose monitoring (CGM) devices still suffer from accuracy and precision issues. In April 2013, we proposed a new conceptual architecture to deal with these problems and render CGM sensors algorithmically smarter, which consists of three modules for denoising, enhancement, and prediction placed in cascade to a commercial CGM sensor. The architecture was assessed on a data set consisting of 24 type 1 diabetes patients collected in four clinical centers of the AP@home Consortium (a European project of 7th Framework Programme funded by the European Committee). This article, as a companion to our prior publication, illustrates the technical details of the algorithms and of the implementation issues. PMID:24124959

  11. On the Use of Evolutionary Algorithms to Improve the Robustness of Continuous Speech Recognition Systems in Adverse Conditions

    Sid-Ahmed Selouani

    2003-07-01

    Full Text Available Limiting the decrease in performance due to acoustic environment changes remains a major challenge for continuous speech recognition (CSR systems. We propose a novel approach which combines the Karhunen-Loève transform (KLT in the mel-frequency domain with a genetic algorithm (GA to enhance the data representing corrupted speech. The idea consists of projecting noisy speech parameters onto the space generated by the genetically optimized principal axis issued from the KLT. The enhanced parameters increase the recognition rate for highly interfering noise environments. The proposed hybrid technique, when included in the front-end of an HTK-based CSR system, outperforms that of the conventional recognition process in severe interfering car noise environments for a wide range of signal-to-noise ratios (SNRs varying from 16 dB to −4 dB. We also showed the effectiveness of the KLT-GA method in recognizing speech subject to telephone channel degradations.

An optimal S-EMS setting was proposed for the billet caster producing billets 150x150 mm.Design/methodology/approach: Impact of different S-EMS settings on central segregation and inner quality of as-cast billets was investigated. A set of longitudinal and transverse samples were analysed including evaluation of baumann prints and central segregation by means of LECO method. Samples of wires for segregation survey in rolled products were picked up as well.Findings: It was observed that application of the strand stirrer (S-EMS is capable to suppress central segregation. However, its impact is visible just to a certain stirring level. Subsequent increasing of stirring intensity does not cause further improvement of segregation in the analyzed central part. On the contrary, stronger white band can be seen in the solidification line. Moreover, concentration gradient between the central part and surrounding ring of negative central segregation is lowered. These two effects can play a significant role in the evaluation of segregation level in rolled wires.Research limitations/implications: Analysis of central segregation in a lower size than used 6 mm.Practical implications: Optimal S-EMS setting seems to be 300 A/14 Hz.Originality/value: Impact of S-EMS setting on changes in central segregation of as-cast billets, relationship between central segregation level in wires and cast structure.

    2012-03-01

    Full Text Available The paper presents the issue of comprehensive automation and monitoring of medium voltage (MV grids as a key element of the Smart Grid concept. The existing condition of MV grid control and monitoring is discussed, and the concept of a solution which will provide the possibility of remote automatic grid reconfiguration and ensure full grid observability from the dispatching system level is introduced. Automation of MV grid switching is discussed in detail to isolate a faulty line section and supply electricity at the time of the failure to the largest possible number of recipients. An example of such automation controls’ operation is also presented. The paper’s second part presents the key role of the quick fault location function and the possibility of the MV grid’s remote reconfiguration for improving power supply reliability (SAIDI and SAIFI indices. It is also shown how an increase in the number of points fitted with faulted circuit indicators with the option of remote control of switches from the dispatch system in MV grids may affect reduction of SAIDI and SAIFI indices across ENERGA-OPERATOR SA divisions.

  17. Continuous mutual improvement of macromolecular structure models in the PDB and of X-ray crystallographic software: the dual role of deposited experimental data

    Macromolecular structures deposited in the PDB can and should be continually reinterpreted and improved on the basis of their accompanying experimental X-ray data, exploiting the steady progress in methods and software that the deposition of such data into the PDB on a massive scale has made possible. Accurate crystal structures of macromolecules are of high importance in the biological and biomedical fields. Models of crystal structures in the Protein Data Bank (PDB) are in general of very high quality as deposited. However, methods for obtaining the best model of a macromolecular structure from a given set of experimental X-ray data continue to progress at a rapid pace, making it possible to improve most PDB entries after their deposition by re-analyzing the original deposited data with more recent software. This possibility represents a very significant departure from the situation that prevailed when the PDB was created, when it was envisioned as a cumulative repository of static contents. A radical paradigm shift for the PDB is therefore proposed, away from the static archive model towards a much more dynamic body of continuously improving results in symbiosis with continuously improving methods and software. These simultaneous improvements in methods and final results are made possible by the current deposition of processed crystallographic data (structure-factor amplitudes) and will be supported further by the deposition of raw data (diffraction images). It is argued that it is both desirable and feasible to carry out small-scale and large-scale efforts to make this paradigm shift a reality. Small-scale efforts would focus on optimizing structures that are of interest to specific investigators. Large-scale efforts would undertake a systematic re-optimization of all of the structures in the PDB, or alternatively the redetermination of groups of structures that are either related to or focused on specific questions. All of the resulting structures should be

  20. Key Factors for a High-Quality Peritoneal Dialysis Program — The Role of the PD Team and Continuous Quality Improvement

    Fang, Wei; Ni, Zhaohui; Qian, Jiaqi

    2014-01-01

    The proportion of end-stage renal disease (ESRD) patients on peritoneal dialysis (PD) has increased very fast in China over the last decade. Renji Hospital, affiliated with Shanghai Jiaotong University School of Medicine, is a recognized high-quality PD unit with a high PD utilization rate, excellent patient and technique survival (1-year and 5-year patient survival rate of 93% and 71%, and 1-year and 5-year technique survival of 96% and 82%, respectively), low peritonitis rate and a well-documented good quality of life of the treated patients. We believe that a dedicated and experienced PD team, a structured patient training program, continuous patient support, establishing and utilizing standardized protocols, starting PD with low dialysis dose, monitoring key performance indicators (KPIs), and continuous quality improvement (CQI) are the key factors underlying this successful PD program.
