    Full Text Available Abstract Due to an increasing awareness of the potential hazardousness of air pollutants, new laws, rules and guidelines have recently been implemented globally. In this respect, numerous studies have addressed traffic-related exposure to particulate matter using stationary technology so far. By contrast, only few studies used the advanced technology of mobile exposure analysis. The Mobile Air Quality Study (MAQS addresses the issue of air pollutant exposure by combining advanced high-granularity spatial-temporal analysis with vehicle-mounted, person-mounted and roadside sensors. The MAQS-platform will be used by international collaborators in order 1 to assess air pollutant exposure in relation to road structure, 2 to assess air pollutant exposure in relation to traffic density, 3 to assess air pollutant exposure in relation to weather conditions, 4 to compare exposure within vehicles between front and back seat (children positions, and 5 to evaluate "traffic zone"-exposure in relation to non-"traffic zone"-exposure. Primarily, the MAQS-platform will focus on particulate matter. With the establishment of advanced mobile analysis tools, it is planed to extend the analysis to other pollutants including NO2, SO2, nanoparticles and ozone.

    Speroff, Theodore; O'Connor, Gerald T

    2004-01-01

    The purpose of this article is to discuss strengths and weaknesses of quasi-experimental designs used in health care quality improvement research. The target groups for this article are investigators in plan-do-study-act (PDSA) quality improvement initiatives who wish to improve the rigor of their methodology and publish their work and reviewers who evaluate the quality of research proposals or published work. A primary purpose of PDSA quality improvement research is to establish a functional relationship between process changes in systems of health care and variation in outcomes. The time series design is the fundamental paradigm for demonstrating such functional relationships. The rigor of a PDSA quality improvement study design is strengthened using replication schemes and research methodology to address extraneous factors that weaken validity of observational studies. The design of PDSA quality improvement research should follow from the purpose and context of the project. Improving the rigor of the quality improvement literature will build a stronger foundation and more convincing justification for the study and practice of quality improvement in health care.

    The efficiency and effectivity of the learning experience is dependent on the teacher quality, thus, enhancing teacher's quality is vital in improving the students learning outcome. Since, the usual top-down one-shot cascading model practice for teachers' professional development in Philippines has been observed to have much information dilution, and the Southeast Asian Ministers of Education Organization demanded the need to develop mathematics teachers' quality standards through the Southeast Asia Regional Standards for Mathematics Teachers (SEARS-MT), thus, an intensive, ongoing professional development model should be provided to teachers. This study was undertaken to determine the impact of Lesson Study on Bulua National High School mathematics teachers' quality level in terms of SEARS-MT dimensions. A mixed method of quantitative-qualitative research design was employed. Results of the analysis revealed that Lesson Study effectively enhanced mathematics teachers' quality and promoted teachers professional development. Teachers positively perceived Lesson Study to be beneficial for them to become a better mathematics teacher.

    The aim of this review was to investigate the quality of the current literature on the transfer of anticonvulsants to breast milk to provide an overview of which anticonvulsants are in need of further research. We reviewed the quality of the available lactation studies for 19 anticonvulsants against the guidelines of the Food and Drug Administration (FDA) and the International Lactation Consultant Association (ILCA). Except for one study on lamotrigine and one case report on gabapentin, no study on anticonvulsants had both the absolute infant dose (AID) and milk to plasma ratio (M : P) correctly assessed. Only one study on carbamazepine, phenytoin and vigabatrin was found that correctly assessed the AID. The main cause for this low number is the lack of essential details in published studies, since 25 of 62 studies were case reports, letters or abstracts. Other major shortcomings were the lack of information on sampling methods, the number of samples in a particular dose interval as well as the low number of study participants. The quality of the current literature on the transfer of anticonvulsants to breast milk is low, except for lamotrigine, which makes it hard to draw conclusions about the safety of the use of anticonvulsants during the lactation period. Therefore, further research is needed. © 2014 The British Pharmacological Society.

    Full Text Available Nowadays, drug research and surveillance after authorisation becomes more and more important for several reasons. Non-interventional studies (NIS investigate various aspects of drug use including efficacy and safety under real life conditions. Such kind of health services research should be on a high scientific, methodological and organisational level. Therefore accompanying measures to improve or to keep the quality are highly recommended. The aim of quality management is: first to avoid bias of results by using an appropriate study design and an adequate data analysis, second to assure authenticity, completeness and validity of the data and third to identify and resolve deficiencies at an early stage. Basic principles are laid down in corresponding guidelines and recommendations of authorities, institutes and societies. Various guidelines for good epidemiological practice (GEP were published by the U.S. Food and Drug Administration (FDA and international and regional societies for epidemiology. In addition in Germany the Federal Institute for Drugs and Medical Devices (BfArM together with the Paul Ehrlich Institute (PEI and the German Association of Research-Based Pharmaceutical Companies (VFA have published respectively recommendations dealing with quality aspects of non-interventional observational studies. Key points are the advanced publishing of information about the project, developing of a study plan/protocol containing the scientific objectives, a sample size justification and a description of the planned analyses and the publishing of a summary of the results timely after completion of the study. The quality of the data can be improved by using standardized case report forms (CRF and the CRF should be reviewed and tested before start of study by some participants. A source data verification (SDV should be performed in randomly selected centres – in between 2% and 5% of the centres depending on the number of participating centres

    Air quality and meteorological data collected at Fermi National Accelerator Laboratory are presented. The data represent baseline values for the pre-construction phase of a proposed coal-gasification test facility. Air quality data were characterized through continuous monitoring of gaseous pollutants, collection of meteorological data, data acquisition and reduction, and collection and analysis of discrete atmospheric samples. Seven air quality parameters were monitored and recorded on a continuous real-time basis: sulfur dioxide, ozone, total hydrocarbons, nonreactive hydrocarbons, nitric oxide, nitrogen oxides, and carbon monoxide. A 20.9-m tower was erected near Argonne's mobile air monitoring laboratory, which was located immediately downwind of the proposed facility. The tower was instrumented at three levels to collect continuous meteorological data. Wind speed was monitored at three levels; wind direction, horizontal and vertical, at the top level; ambient temperature at the top level; and differential temperature between all three levels. All continuously-monitored parameters were digitized and recorded on magnetic tape. Appropriate software was prepared to reduce the data. Statistical summaries, grphical displays, and correlation studies also are presented.

    Human biospecimens are subjected to collection, processing, and storage that can significantly alter their molecular composition and consistency. These biospecimen preanalytical factors, in turn, influence experimental outcomes and the ability to reproduce scientific results. Currently, the extent and type of information specific to the biospecimen preanalytical conditions reported in scientific publications and regulatory submissions varies widely. To improve the quality of research that uses human tissues, it is crucial that information on the handling of biospecimens be reported in a thorough, accurate, and standardized manner. The Biospecimen Reporting for Improved Study Quality (BRISQ) recommendations outlined herein are intended to apply to any study in which human biospecimens are used. The purpose of reporting these details is to supply others, from researchers to regulators, with more consistent and standardized information to better evaluate, interpret, compare, and reproduce the experimental results. The BRISQ guidelines are proposed as an important and timely resource tool to strengthen communication and publications on biospecimen-related research and to help reassure patient contributors and the advocacy community that their contributions are valued and respected.

    A fuel quality processing study to provide a data base for an intelligent tradeoff between advanced turbine technology and liquid fuel quality, and also, to guide the development of specifications of future synthetic fuels anticipated for use in the time period 1985 to 2000 is given. Four technical performance tests are discussed: on-site pretreating, existing refineries to upgrade fuels, new refineries to upgrade fuels, and data evaluation. The base case refinery is a modern Midwest refinery processing 200,000 BPD of a 60/40 domestic/import petroleum crude mix. The synthetic crudes used for upgrading to marketable products and turbine fuel are shale oil and coal liquids. Of these syncrudes, 50,000 BPD are processed in the existing petroleum refinery, requiring additional process units and reducing petroleum feed, and in a new refinery designed for processing each syncrude to produce gasoline, distillate fuels, resid fuels, and turbine fuel, JPGs and coke. An extensive collection of synfuel properties and upgrading data was prepared for the application of a linear program model to investigate the most economical production slate meeting petroleum product specifications and turbine fuels of various quality grades. Technical and economic projections were developed for 36 scenarios, based on 4 different crude feeds to either modified existing or new refineries operated in 2 different modes to produce 7 differing grades of turbine fuels. A required product selling price of turbine fuel for each processing route was calculated. Procedures and projected economics were developed for on-site treatment of turbine fuel to meet limitations of impurities and emission of pollutants.

    One of the major goals of NASA’s Earth Observing System (EOS) program was to study the Earth-Atmosphere System in an integrated fashion. As part of this vision, a series of individual and multi-sensor satellites were launched. With the launch of multiple sensors on several satellites, there is an increasing need to not only analyze data from individual sensors but from a combination of sensors on the same satellite or multiple satellites. Being able to juxtapose and combine these data sets should increase our ability to more effectively analyze various research scenarios. Currently, there are limited tools available for classifying images into one of several classes (e.g. clouds, aerosol, vegetation, desert, etc) on a pixel-by-pixel basis especially in complex cases when aerosols are mixed with clouds or when aerosols are over inhomogeneous surfaces. For example, the MODIS algorithms for detecting aerosols over land and ocean use a set of simple spatial and spectral thresholds that may not be adequate for complex cases over deserts when the surface is bright with clouds and aerosols in different layers and misclassification is possible. Over the Saharan desert mineral dust could be mixed with biomass burning aerosols, could occur in different layers, or thin cirrus cloud could pose additional ‘contamination’ problems. This poster will present GLIDER, a free software tool currently being developed to address these science needs. GLIDER provides users with a easy to use tool to visualize, analyze and mine satellite imagery. The poster will describe the tool’s unique features that will make it invaluable scientists for conducting air quality studies based on satellite imagery.

  8. High Quality Data for Grid Integration Studies

    As variable renewable power penetration levels increase in power systems worldwide, renewable integration studies are crucial to ensure continued economic and reliable operation of the power grid. The existing electric grid infrastructure in the US in particular poses significant limitations on wind power expansion. In this presentation we will shed light on requirements for grid integration studies as far as wind and solar energy are concerned. Because wind and solar plants are strongly impacted by weather, high-resolution and high-quality weather data are required to drive power system simulations. Future data sets will have to push limits of numerical weather prediction to yield these high-resolution data sets, and wind data will have to be time-synchronized with solar data. Current wind and solar integration data sets are presented. The Wind Integration National Dataset (WIND) Toolkit is the largest and most complete grid integration data set publicly available to date. A meteorological data set, wind power production time series, and simulated forecasts created using the Weather Research and Forecasting Model run on a 2-km grid over the continental United States at a 5-min resolution is now publicly available for more than 126,000 land-based and offshore wind power production sites. The National Solar Radiation Database (NSRDB) is a similar high temporal- and spatial resolution database of 18 years of solar resource data for North America and India. The need for high-resolution weather data pushes modeling towards finer scales and closer synchronization. We also present how we anticipate such datasets developing in the future, their benefits, and the challenges with using and disseminating such large amounts of data.

    2009-04-01

    To find out an approach to water quality management through correlation studies between various water quality parameters, the statistical regression analysis for six data points of underground drinking water of different hand pumps at J. P. Nagar was carried out. The comparison of estimated values with W.H.O drinking water standards revealed that water of the study area is polluted with reference to a number of physico-chemical parameters studied. Regression analysis suggests that conductivity of underground water is found to be significantly correlated with eight out of twelve water quality parameters studied. It may be suggested that the underground drinking water quality at J. P. Nagar can be checked very effectively by controlling the conductivity of water. The present study may be treated one step forward towards the water quality management.

    GreenLightTM procedure is an effective and economical way of treatment of benign prostate hyperplasia (BPH); there are almost a million of patients treated with GreenLightTM worldwide. During the surgical procedure, the surgeon or physician will rely on the monitoring video system to survey and confirm the surgical progress. There are a few obstructions that could greatly affect the image quality of the monitoring video, like laser glare by the tissue and body fluid, air bubbles and debris generated by tissue evaporation, and bleeding, just to name a few. In order to improve the physician's visual experience of a laser surgical procedure, the system performance parameter related to image quality needs to be well defined. However, since image quality is the integrated set of perceptions of the overall degree of excellence of an image, or in other words, image quality is the perceptually weighted combination of significant attributes (contrast, graininess …) of an image when considered in its marketplace or application, there is no standard definition on overall image or video quality especially for the no-reference case (without a standard chart as reference). In this study, Subjective Quality Factor (SQF) and acutance are used for no-reference image quality evaluation. Basic image quality parameters, like sharpness, color accuracy, size of obstruction and transmission of obstruction, are used as subparameter to define the rating scale for image quality evaluation or comparison. Sample image groups were evaluated by human observers according to the rating scale. Surveys of physician groups were also conducted with lab generated sample videos. The study shows that human subjective perception is a trustworthy way of image quality evaluation. More systematic investigation on the relationship between video quality and image quality of each frame will be conducted as a future study.

    Umair Shahid, Syed; Iqbal, Javed

    2016-10-01

    Water quality is considered as a major issue in mega cities of developing countries. The city of Lahore has over 10 million populations with the highest population density in the Punjab Province, Pakistan. Groundwater is the main source of drinking water in Lahore. The groundwater quality should be regularly monitored to cope up with drinking water quality issues. The water quality index (WQI), previously used in many studies was usually based on one-year data to analyze the water quality situation of the study area. However, the results obtained from the data, based on single observation from different points may have distortion. This might have occurred due to the inclusion of multiple types of errors induced in the data as a result of improper sampling design, lack of expertise in terms of both sampling method and sample testing, instrumental and human errors, etc. Therefore, the study evaluated the groundwater physicochemical parameters (turbidity, pH, total dissolved solids, hardness, chlorides, alkalinity and calcium) for three years. The averaged water quality index (AWQI) was computed using ArcGIS 10.3 model builder. The AWQI map indicated that the water quality in the study area was generally good except in few places like Anarkali, Baghbanpura, Allama Iqbal Town, Mughalpura and Mozang due to relatively higher turbidity levels. The results of this study can be used for decision making regarding provision of clean drinking water to the city of Lahore. Moreover, the methodology adopted in this study can be implemented in other mega cities as well to monitor groundwater quality.

    2015-10-01

    Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a single measure for evaluating the multiple-item service quality construct based on the SERVQUAL model. A slack-based measure (SBM) of efficiency with constant inputs is used to calculate the PSQI. In addition, a non-linear programming model based on the SBM is proposed to delineate an improvement guideline and improve service quality. An empirical study is conducted to assess the applicability of the method proposed in this study. A large number of studies have used DEA as a benchmarking tool to measure service quality. These models do not propose a coherent performance evaluation construct and consequently fail to deliver improvement guidelines for improving service quality. The DEA models proposed in this study are designed to evaluate and improve service quality within a comprehensive framework and without any dependency on external data.

    Full Text Available The success of every housing area is determined by its user satisfaction level, living there. The quality of the house, its spaces within the unit, housing neighbourhood and green open space can directly influence the quality of life. Limitation of space following high land cost in an urban area, evaluation of the housing environment as a whole including the green open space needs to be studied as it affects the residents’ satisfaction level. This study concentrates on spaces within a housing area to evaluate the residents’ level of satisfaction of the Taman Melati Mastika (TMM, Kuala Lumpur and to understand how they perceived their quality of life through the housing environment and the availability of green open space. Thus, this research was carried out through site observation and analysis, and self-administered questionnaire survey. 247 questionnaire surveys were distributed to the residents of TMM and (n=62 responded. When focused on the housing unit, this study provides insight on the types of outdoor spaces (front yard-front lane and backyard-back lane and their elements and utilization, and quality of housing spaces toward users’ quality of life in TMM, Kuala Lumpur. On the green open space, the assessment of the quality of life is based on three factors that are the safety level of the neighbourhood and park, health issues related to housing environment and park as well as the satisfaction on the housing amenities and park facilities. The result of this study suggests that the residents are satisfied with the existing spaces within their compound and adjacent to it and this lead towards the overall satisfaction living in the area. The quality of space and good utilisation of housing areas can lead towards a better quality of life in the Terrace housing area is confirmed.

Evening chronotype is associated with poor sleep quality, more mind wandering and more daydreaming; negative affect is also a mutual correlate. This exploratory study investigated how mind wandering and daydreaming are related to different aspects of sleep quality, and whether sleep quality influences the relationships between mind wandering/daydreaming and negative affect, and mind wandering/daydreaming and chronotype. Three surveys (Ns = 213; 190; 270 were completed with Chinese adults aged 18-50, including measures of sleep quality, daytime sleepiness, mind wandering, daydreaming, chronotype and affect (positive and negative. Higher frequencies of mind wandering and daydreaming were associated with poorer sleep quality, in particular with poor subjective sleep quality and increased sleep latency, night-time disturbance, daytime dysfunction and daytime sleepiness. Poor sleep quality was found to partially mediate the relationships between daydreaming and negative affect, and mind wandering and negative affect. Additionally, low positive affect and poor sleep quality, in conjunction, fully mediated the relationships between chronotype and mind wandering, and chronotype and daydreaming. The relationships between mind wandering/daydreaming and positive affect were also moderated by chronotype, being weaker in those with a morning preference. Finally, while daytime sleepiness was positively correlated with daydream frequency, it was negatively correlated with a measure of problem-solving daydreams, indicating that more refined distinctions between different forms of daydreaming or mind wandering are warranted. Overall, the evidence is suggestive of a bi-directional relationship between poor sleep quality and mind wandering/daydreaming, which

    2010-07-01

    Successful stimulation and extraction of hydrocarbons from unconventional reservoirs have created different approaches to the stimulation process. Types of treatment vary from slickwater stimulations, low dosages of polyacrylamide, conventional crosslinked, or linear gelled fluids. There has also been successful treatments in implementing a high-quality foam stimulation in some shale formations. The advantage of using a high quality foam is its reduced environmental impact as it uses very small amounts of water as compared to high-rate slickwater stimulations. However, there is little published information on high-quality fluid foam properties. In order to examine the rheological properties of high-quality foamed fracturing fluids and compare it to other fluids that are common in fracturing treatments, this paper presented a study that examined the fluid characteristics of high-quality foams as compared to typical 50-70 quality foams. The study demonstrated trends of viscosity, foam stability and temperature sensitivity of high-quality foams using xanthan, guar-based gelling agents and viscoelastic base fluids. The paper described the test equipment and procedures, as well as the test results. The tests using guar as the base fluid gellant demonstrated increasing viscosity with increased foam quality. 2 tabs., 22 figs.

    Automatic methods to evaluate the perceptual quality of a digital video sequence have widespread applications wherever the end-user is a human. Several objective video quality assessment (VQA) algorithms exist, whose performance is typically evaluated using the results of a subjective study performed by the video quality experts group (VQEG) in 2000. There is a great need for a free, publicly available subjective study of video quality that embodies state-of-the-art in video processing technology and that is effective in challenging and benchmarking objective VQA algorithms. In this paper, we present a study and a resulting database, known as the LIVE Video Quality Database, where 150 distorted video sequences obtained from 10 different source video content were subjectively evaluated by 38 human observers. Our study includes videos that have been compressed by MPEG-2 and H.264, as well as videos obtained by simulated transmission of H.264 compressed streams through error prone IP and wireless networks. The subjective evaluation was performed using a single stimulus paradigm with hidden reference removal, where the observers were asked to provide their opinion of video quality on a continuous scale. We also present the performance of several freely available objective, full reference (FR) VQA algorithms on the LIVE Video Quality Database. The recent MOtion-based Video Integrity Evaluation (MOVIE) index emerges as the leading objective VQA algorithm in our study, while the performance of the Video Quality Metric (VQM) and the Multi-Scale Structural SIMilarity (MS-SSIM) index is noteworthy. The LIVE Video Quality Database is freely available for download1 and we hope that our study provides researchers with a valuable tool to benchmark and improve the performance of objective VQA algorithms.

    Full Text Available The scenario of quality is expanding exponentially. In the present-day world, quality is now in the driver's seat. With this globalisation of industrial products, many problems and opportunities have risen, primarily due to inconsistent standards existing in the market. The International Standards Organisation has tried (and seem to be very successful in doing so to standardise a minimum level of quality norms. These norms act as the foundation to implements total quality management (TQM. TQM has been identified as a philosophy of interdependent characteristics, such as customer focus, commitment, measurement, systematic support, and continuous improvement. This paper presents a case study on the implementation of ISO 9002: 1994 at Kerala Hitech Industries (KELTEC, with the benefits, hurdles faced, and shortcomings. Upgradation of KELTEC's quality management system to the requirements of ISO 9001: 2000 is currently under progress.

    Connolly, Regina

    Despite the fact that service quality is a critical determinant of website success, studies show that consumers frequently view the service quality delivered through websites as unsatisfactory. This paper outlines a study that investigated the dimensions of website service excellence valued by Irish customers of a small-to-medium enterprise specialising in gifts. The E-S-QUAL measurement instrument was applied to the customers who purchase products online from this retailer, in order to determine their purchasing patterns and the dimensions of e-service quality that they value. The results of this study indicate the effectiveness of the instrument in determining gaps in e-service quality. The findings will be of benefit both to practitioners and researchers seeking to improve their understanding of the factors that contribute towards the creation and maintenance of consumer satisfaction in Irish online transactions.

    Full Text Available Quality of an academic study programme is evaluated by many: employees (internal evaluation and by external evaluators: experts, agencies and organisations. Internal and external evaluation of an academic programme follow written structure that resembles on one of the quality models. We believe the quality models (mostly derived from EFQM excellence model don’t fit very well into non-profit activities, policies and programmes, because they are much more complex than environment, from which quality models derive from (for example assembly line. Quality of an academic study programme is very complex and understood differently by various stakeholders, so we present dimensional evaluation in the article. Dimensional evaluation, as opposed to component and holistic evaluation, is a form of analytical evaluation in which the quality of value of the evaluand is determined by looking at its performance on multiple dimensions of merit or evaluation criteria. First stakeholders of a study programme and their views, expectations and interests are presented, followed by evaluation criteria. They are both joined into the evaluation model revealing which evaluation criteria can and should be evaluated by which stakeholder. Main research questions are posed and research method for each dimension listed.

    Full Text Available This study examines audit committee quality and its relationship with financial reporting quality. The population of this study consists of the companies listed in Bombay Stock Exchange (BSE between years 2002 and 2012. Using Godden sample size formula, 133 companies are selected randomly for the study. It is found that in most of the equity based listed companies at BSE under study have complied with the legal formalities, for instance, appointment of independent directors, number of meetings, size of the audit committee, legal qualifications and financial qualifications of the directors, as they were required for the listing at a stock exchange in India. Further, the analysis and tests state that board size, audit committee meetings and its size have relationship with the financial reporting practices, but the CEO tenure and hold, board independence, net income, proportion of independent directors on board, legal qualifications and financial qualifications of the directors and overlap of audit committee members on compensation committee, have no influence on the financial reporting practices. Thus, it may be inferred that the companies may improve the financial reporting quality, by managing the board size, audit committee meetings and size, as these characteristics have significant relationship with financial reporting quality.

    The authors conducted air quality measurements of the criteria pollutants carbon monoxide, nitrogen oxides, and ozone together with meteorological measurements at a park site southeast of College Station, TX, during the 2006 Texas Air Quality Study II (TexAQS). Ozone, a primary focus of the measurements, was above 80 ppb during 3 days and above 75 ppb during additional 8 days in summer 2006, suggestive of possible violations of the ozone National Ambient Air Quality Standard (NAAQS) in this area. In concordance with other air quality measurements during the TexAQS II, elevated ozone mixing ratios coincided with northerly flows during days after cold front passages. Ozone background during these days was as high as 80 ppb, whereas southerly air flows generally provided for an ozone background lower than 40 ppb. Back trajectory analysis shows that local ozone mixing ratios can also be strongly affected by the Houston urban pollution plume, leading to late afternoon ozone increases of as high as 50 ppb above background under favorable transport conditions. The trajectory analysis also shows that ozone background increases steadily the longer a southern air mass resides over Texas after entering from the Gulf of Mexico. In light of these and other TexAQS findings, it appears that ozone air quality is affected throughout east Texas by both long-range and regional ozone transport, and that improvements therefore will require at least a regionally oriented instead of the current locally oriented ozone precursor reduction policies.

    Full Text Available Purpose: Computed tomography (CT, is an X-ray procedure that generates high quality cross-sectional images of the body, and by comparison to other radiological diagnosis, is responsible for higher doses to patients. This work studies the doses and image qualities produced from the default primary scanning factors of a Siemens CT machine and afterwards came up with scanning protocols that allow radiologists to obtain the necessary diagnostic information while reducing radiation doses to as low as reasonably achievable. Methods: Approximately 1000 CT scans from mostly common examinations; head, thorax, abdomen and pelvis routines were selected and analyzed for their image quality and radiation doses over a two year interval. Dose measurements were performed for the same routines using Computed Tomography Dose Index (CTDI phantoms, RTI barracuda system with electrometer, and CT dose Profiler detector to evaluate the doses delivered during these CT procedures. Subsequently, image quality checks were performed using the CT Catphan 600 and anthropomorphic phantoms. CTDI and Dose Length Product (DLP values were calculated for each scan. From analyzing these measurements, the appropriate machine scanning parameters were adjusted to reduce radiation does while at the same time providing good image quality.Results: Doses to patients using the default head sequence protocol had an average CTDIvol value of 65.45 mGy and a range of 7.10-16.80 mGy for thorax, abdomen and pelvis examinations whiles the new protocol had an average CTDIvol of 58.32 mGy for the head and a range of 3.83-15.24 mGy for the truck region. The DLP value for default head scans decreased from an average of 2279.85 mGy.cm to 874.53 mGy.cm with the new protocol. Tube potentials (KV and tube current-time (mAs had an effect on spatial resolution and low contrast detectability as well as doses. Conclusion: From the new protocols, lower values of KV and mAs together with other factors were

    The Nordic countries have a long tradition of providing comparable and high quality cancer data through the national population-based cancer registries and the capability to link the diverse large-scale biobanks currently in operation. The joining of these two infrastructural resources can provide a study base for large-scale studies of etiology, treatment and early detection of cancer. Research projects based on combined data from cancer registries and biobanks provides great opportunities, but also presents major challenges. Biorepositories have become an important resource in molecular epidemiology, and the increased interest in performing etiological, clinical and gene-environment-interaction studies, involving information from biological samples linked to population-based cancer registries, warrants a joint evaluation of the quality aspects of the two resources, as well as an assessment of whether the resources can be successfully combined into a high quality study. While the quality of biospecimen handling and analysis is commonly considered in different studies, the logistics of data handling including the linkage of the biobank with the cancer registry is an overlooked aspect of a biobank-based study. It is thus the aim of this paper to describe recommendations on data handling, in particular the linkage of biobank material to cancer registry data and the quality aspects thereof, based on the experience of Nordic collaborative projects combining data from cancer registries and biobanks. We propose a standard documentation with respect to the following topics: the quality control aspects of cancer registration, the identification of cases and controls, the identification and use of data confounders, the stability of serum components, historical storage conditions, aliquoting history, the number of freeze/thaw cycles and available volumes.

    Obesity affects one in three American adult women and is associated with overall mortality and major morbidities. A composite diet index to evaluate total diet quality may better assess the complex relationship between diet and obesity, providing insights for nutrition interventions. The purpose of the present investigation was to determine whether diet quality, defined according to the previously validated Framingham nutritional risk score (FNRS), was associated with the development of overweight or obesity in women. Over 16 years, we followed 590 normal-weight women (BMI Framingham Offspring and Spouse Study who presented without CVD, cancer or diabetes at baseline. The nineteen-nutrient FNRS derived from mean ranks of nutrient intakes from 3 d dietary records was used to assess nutritional risk. The outcome was development of overweight or obesity (BMI > or = 25 kg/m2) during follow-up. In a stepwise multiple logistic regression model adjusted for age, physical activity and smoking status, the FNRS was directly related to overweight or obesity (P for trend = 0.009). Women with lower diet quality (i.e. higher nutritional risk scores) were significantly more likely to become overweight or obese (OR 1.76; 95 % CI 1.16, 2.69) compared with those with higher diet quality. Diet quality, assessed using a comprehensive composite nutritional risk score, predicted development of overweight or obesity. This finding suggests that overall diet quality be considered a key component in planning and implementing programmes for obesity risk reduction and treatment recommendations.

    Referring to the rules for agricultural seed testing (GB /T 3543-1995) issued by China, the test of sampling, seed purity, weight per 1 000 seeds, seed moisture, seed viability and germination rate had been studied for screening seed quality test methods of Pesudostellaria heterophylla. The seed quality from different collection areas was measured. The results showed that at least 6.5 g seeds should be sampled and passed through 10-mesh sieve for purity analysis. The weight of 1 000 seeds was determined by using the 500-seed method. The phenotypic observation and size measurement were used for authenticity testing. The seed moisture was determined under the higher temperature (130 ± 2) degrees C for 5 hours. The seeds were dipped into 0.2% TTC sustaining 1 hour at 40 degrees C, then the viability could be determined. The break dormancy seeds were cultured on sand at 10 degrees C. K cluster analysis was applied for the data analysis, the seed quality from different collection areas grading of P. Heterophylla was described as three grades. The seed quality of each grade should reach following requirements: for first grade seeds, germination rate ≥ 86%, 1 000-grain weight ≥ 2.59 g, purity ≥ 87%, moisture ≤ 13.1%; for second grade seeds, germination rate ≥ 70%, 1 000-grain weight ≥ 2.40 g, purity ≥ 77%, moisture ≤ 14.3%; for third grade seeds, germination rate ≥ 41%, 1 000-grain weight ≥ 2.29 g, purity ≥ 76%, moisture ≤ 15.8%. The seed testing methods for quality items of P. heterophylla had been initially established, as well as the primary P. heterophylla seed quality classification standard.

    2008-03-15

    The Border Air Quality Study (BAQS) is an ongoing study which supports the development of an international strategy for the Georgia Basin-Puget Sound airshed. The study investigates the association of health risks with the exposure to a range of air pollutants. It identified links between air pollutants and several health impacts ranging from asthma to birthweight. The tools developed for studying air quality provide greater spatial resolution, thus enabling the identification of pollution hot spots that require monitoring and intervention. The tools also provide spatially accurate exposure data for future research and enable land-use decisions that reduce risk to the most vulnerable populations, including children and the elderly. The study found that traffic-related air pollution is an additional risk factor for disease, such as bronchiolitis, asthma and middle ear infections in children. Although air pollution is a known risk factor for cardiovascular disease, relatively few studies have evaluated the effects of chronic exposures. Therefore, the BAQS is currently assessing the relationship between air quality and cardiovascular diseases in the Metro Vancouver area, with particular attention to the combined effects of traffic-related air pollution and noise pollution. Wood smoke was also found to be an important source of air pollution, even in urban centres. The study showed that building design and ventilation can help reduce infiltration of air pollutants into buildings. It was concluded that despite some concerns, the air quality in the Georgia-Basin-Puget Sound region is good compared to other major metropolitan areas. Air quality managers can use the study to evaluate different policy scenarios and the associated economic costs of air pollution. 5 figs.

    Full Text Available Aim: Diabetes Mellitus, a chronic progressive disorder, characterized with hyperglycemia and derangements of carbohydrate, protein and lipid metabolism. During its course microvascular, macrovascular and neurologic complications may develop. Being a patient with a chronic disorder like diabetes mellitus not only limits physical activities but also hinders other activities such as social life, education, career, occupational opportunities, and transportation, thus it influences individuals life quality unfavorably. Material and Method: Patient group with 229 individuals diagnosed with Type 2 DM and control group with 77 healthy individuals are involved in this study. A form questioning socio-demographic characteristics, past medical and family history and SF36 and EQ-5d life quality surveys are applied to individuals. 130 of the 306 people included in the study (42.5% in the group with complications, 99 (32.4% complications in the group, 77 (25.2% were in the control group.

    McIver, Jessica

    2012-01-01

    Data quality assessment plays an essential role in the quest to detect gravitational wave signals in data from the LIGO and Virgo interferometric gravitational wave detectors. Interferometer data contains a high rate of noise transients from the environment, the detector hardware, and the detector control systems. These transients severely limit the statistical significance of gravitational wave candidates of short duration and/or poorly modeled waveforms. This paper describes the data quality studies that have been performed in recent LIGO and Virgo observing runs to mitigate the impact of transient detector artifacts on the gravitational wave searches.

    2013-08-01

    Since the inception of the economic reform, marital relationship in urban China has undergone dramatic transformations. Though the burgeoning body of scholarly research has demonstrated that marital quality has increasingly become an important aspect of family life among married persons in urban China, both the conceptualization and measurement of marital quality remain underdeveloped. The purpose of this pilot study is to develop and validate a comprehensive and culturally appropriate marital quality scale, namely the Chinese Marital Quality Scale (CMQS). Results from the confirmatory factor analysis (CFA) conducted on a sample of 387 married persons from Beijing indicate that the CMQS can be conceptualized as a two-factorial and multidimensional construct, encompassing marital happiness, marital interaction, marital disagreement, marital problem, and marital instability. Additional statistical analyses also indicate that the CMQS has exhibited satisfactory reliability and concurrent validity. It is thus concluded that the CMQS is a reliable and valid instrument to measure marital quality in contemporary Beijing and possibly in other Chinese cities.

    Science.gov (United States)

    Barcellos, Paulo Fernando Pinto

    The dissertation deals with the case of CEEE-Companhia Estadual de Energia Eletrica, an electric power utility located in Rio Grande do Sul, the southernmost state of Brazil. Customer satisfaction with the services provided by CEEE is investigated within three groups of consumers: residential, commercial, and industrial. The purpose of the dissertation is to find answers to the following research questions: (1) What is service quality in public utilities, and particularly in an electric power company? (2) What service quality dimensions do customers want to be provided and favor the most? (3) How does the market measure service quality? (4) What should be done by companies, and particularly by an electric utility monopoly, to increase the performance of the rendered service? (5) How does this impact customer satisfaction, retention, and intention to recommend? and (6) How do we start a company-wide quality program provided that the resources are scarce and therefore priorities should be set forth? To investigate the posed questions, the study begins with an exploratory survey of CEEE's Board. The survey is followed by qualitative research of the three customer groups. After qualitative analysis of the data is concluded, questionnaires for the quantitative research, as well as hypothetical models, are developed. Dillman's "Total Design Method" is used to design the questionnaires. The basic ACSI (American Customer Satisfaction Model) is used to approach customer satisfaction. Data are processed by PLS (Partial Least Squares) which follows the procedure developed at the National Quality Research Center of the University of Michigan Business School. In summary, commercial customers are the most dissatisfied with the services provided by CEEE, while residential customers are the most satisfied. To improve quality, priority should be placed on commercial customers and include efforts to improve productivity gains throughout the company. Also, CEEE's image should be

    Objectives Evaluate the quality of care provided patients with acute myocardial infarction and compare with similar national and regional data. Design Case series. Setting The Strong Heart Study has extensive population-based data related to cardiovascular events among American Indians living in three rural regions of the United States. Participants Acute myocardial infarction cases (72) occurring between 1/1/2001 and 12/31/2006 were identified from a cohort of 4549 participants. Outcome measures The proportion of cases that were provided standard quality of care therapy, as defined by the Healthcare Financing Administration and other national organizations. Results The provision of quality services, such as administration of aspirin on admission and at discharge, reperfusion therapy within 24 hours, prescription of beta blocker medication at discharge, and smoking cessation counseling were found to be 94%, 91%, 92%, 86% and 71%, respectively. The unadjusted, 30 day mortality rate was 17%. Conclusion Despite considerable challenges posed by geographic isolation and small facilities, process measures of the quality of acute myocardial infarction care for participants in this American Indian cohort were comparable to that reported for Medicare beneficiaries nationally and within the resident states of this cohort.

    Green (vegetated) roofs are emerging as practical strategies to improve the environmental quality of cities. However, the impact of green roofs on the storm water quality remains a topic of concern to city planners and environmental policy makers. This study investigated whether green roofs act as a source or a sink of various metals (Na, K, Ca, Mg, Al, Fe, Cu, Cd, Pb, Zn, Mn, Cr, Ni, Li and Co), inorganic anions (NO3-, NO2-, PO4(3-), SO4(2-), Cl-, F- and Br-) and cation (NH4+). A series of green roof assemblies were constructed. Four different real rain events and several artificial rain events were considered for the study. Results showed that concentrations of most of the chemical components in runoff were highest during the beginning of rain events and subsided in the subsequent rain events. Some of the important components present in the runoff include Na, K, Ca, Mg, Li, Fe, Al, Cu, NO3-, PO4(3-) and SO4(2-). However, the concentration of these chemical components in the roof runoff strongly depends on the nature of substrates used in the green roof and the volume of rain. Based on the USEPA standards for freshwater quality, we conclude that the green roof used in this study is reasonably effective except that the runoff contains significant amounts of NO3- and PO4(3-).

    Among the biomonitors of environmental quality, there is a lack of studies on using invertebrates to evaluate quantitatively chemical elements in ecosystems. This group of animals is quite numerous, widely distributed and adaptable to the most diverse environmental conditions. These features are very useful for the environmental quality assessment, as well as the several occurring insect-plant interactions performing essential functions in ecosystems. The objective of this work is to study the variability of chemical composition of invertebrate orders for using in environmental quality monitoring studies. Instrumental neutron activation analysis - INAA was applied to determine some nutrients and trace elements in invertebrate samples. Sampling by pitfall traps was carried out in riverine ecosystems from the urban area from the Piracicaba Municipality, State of Sao Paulo, Brazil. Invertebrate and reference material samples were irradiated in the nuclear research reactor IEA-R1, Instituto de Pesquisas Energeticas e Nucleares - IPEN/CNEN. Fragments of a Ni-Cr alloy were irradiated for monitoring the thermal neutron flux. Hymenoptera order was considered the most representative according to the total number of sampled species (about 60%). Significant amounts of Ba, Br, Fe and Sc were found in invertebrates of the order Opiliones. Potassium, rubidium and zinc were highly accumulated in species from Blattodea order, indicating a consistent pattern of accumulation for this invertebrate order. Taking into account the abundance of Hymenoptera order, the chemical composition of its species was significant different at the 95% confidence level for Br and Na in the sampled locals. (author)

    Full Text Available Aquaponic systems are integrated systems that combine fish farming and different types of plants. It involves a dynamic interaction between fish plants and bacteria. Fish and plants are dependent the equilibrium of dissolved nutrients and water quality. Only by striking a balance between dissolved nutrients and water quality we can achieve a large production of plants and healthy fish. Thus, control of water quality in an aquaponic system is essential in order to obtain performance in raising fish and plants. The experiment was conducted in the laboratory of Fisheries and Aquaculture of the Faculty of Animal Science of the University of Agronomic Sciences and Veterinary Medicine of Bucharest within a period of 30 days. The system used for the experiment was designed and developed in the laboratory mentioned above. The plant used for water treatment in the system was basil (Ocimum basilicum. Fish species grown in the system was culture carp (Cyprinus carpio.

    Through collecting the spectral signals of TIG and MIG welding arc with spectrometer, the arc light radiations were analyzed based on the basic theory of plasma physics. The radiation of welding arc distributes over a broad range of frequency, from infrared to ultraviolet. The arc spectrum is composed of line spectra and continuous spectra. Due to the variation of metal density in the welding arc, there is great difference between the welding arc spectra of TIG and MIG in both their intensity and distribution. The MIG welding arc provides more line spectra of metal and the intensity of radiation is greater than TIG. The arc spectrum of TIG welding is stable during the welding process, disturbance factors that cause the spectral variations can be reflected by the spectral line related to the corresponding element entering the welding arc. The arc spectrum of MIG welding will fluctuate severely due to droplet transfer, which produces "noise" in the line spectrum aggregation zone. So for MIG welding, the spectral zone lacking spectral line is suitable for welding quality diagnosis. According to the characteristic of TIG and MIG, special spectral zones were selected for welding quality diagnosis. For TIG welding, the selected zone is in ultraviolet zone (230-300 nm). For MIG welding, the selected zone is in visible zone (570-590 nm). With the basic theory provided for welding quality diagnosis, the integral intensity of spectral signal in the selected zone of welding process with disturbing factor was studied to prove the theory. The results show that the welding quality and disturbance factors can be diagnosed with good signal to noise ratio in the selected spectral zone compared with signal in other spectral zone. The spectral signal can be used for real-time diagnosis of the welding quality.

    In urban cities, the environmental services are the responsibility of the public sector, where piped water supply is the norm for urban household. Likewise, in Beirut City (capital of Lebanon) official water authorities are the main supplier of domestic water through a network of piping system that leaks in many areas. Beirut City and its suburbs are overpopulated since it is the residence of 1/3 of the Lebanese citizens. Thus, Beirut suffers deficiency in meeting its water demand. Water rationing, as a remedial action, is firmly established since four decades by the Lebanese Water Authorities. Consumers resorted then to private wells to supplement their domestic water needs. Consequently, household water quality is influenced by external factors relating to well water characteristics and internal factors depending on the types of the pipes of the distribution network and cross connections to sewer pipes. These factors could result in chemical and microbial contamination of drinking water. The objective of this study is to investigate domestic water quality variation in Beirut City emerging form the aforementioned factors. The presented work encircles a typical case study of Beirut City (Ras Beirut). Results showed deterioration pattern in domestic water quality. The predicted metal species and scales within the water pipes of distribution network depended on water pH, hardness, sulfate, chloride, and iron. The corrosion of iron pipes mainly depended on Mg hardness.

    Agriculture, rapid urbanization and geochemical processes have direct or indirect effects on the chemical composition of groundwater and aquifer geochemistry. Hydro-chemical investigations, which are significant for assessment of water quality, were carried out to study the sources of dissolved ions in groundwater of Dinajpur district, northern Bangladesh. The groundwater samplish were analyzed for physico-chemical properties like pH, electrical conductance, hardness, alkalinity, total dissolved solids and Ca2+, Mg2+, Na+, K+, CO3(2-), HCO3(-), SO4(2-) and Cl- ions, respectively. Based on the analyses, certain parameters like sodium adsorption ratio, soluble sodium percentage, potential salinity, residual sodium carbonate, Kelly's ratio, permeability index and Gibbs ratio were also calculated. The results showed that the groundwater of study area was fresh, slightly acidic (pH 5.3-6.4) and low in TDS (35-275 mg I(-1)). Ground water of the study area was found suitable for irrigation, drinking and domestic purposes, since most of the parameters analyzed were within the WHO recommended values for drinking water. High concentration of NO3- and Cl- was reported in areas with extensive agriculture and rapid urbanization. Ion-exchange, weathering, oxidation and dissolution of minerals were major geochemical processes governing the groundwater evolution in study area. Gibb's diagram showed that all the samples fell in the rock dominance field. Based on evaluation, it is clear that groundwater quality of the study area was suitable for both domestic and irrigation purposes.

    Satellite instruments have had great success in monitoring the stratospheric ozone and in understanding the processes that control its daily to decadal scale variations. This field is now reaching its zenith with a number of satellite instruments from the US, Europe and Canada capping several decades of active research in this field. The primary public policy imperative of this research was to make reliable prediction of increases in biologically active surface UV radiation due to human activity. By contrast retrieval from satellite data of atmospheric constituents and photo-chemically active radiation that affect air quality is a new and growing field that is presenting us with unique challenges in measurement and data interpretation. A key distinction compared to stratospheric sensors is the greatly enhanced role of clouds, aerosols, and surfaces (CAS) in determining the quality and quantity of useful data that is available for air quality research. In our presentation we will use data from several sensors that are currently flying on the A-train satellite constellation, including OMI, MODIS, CLOUDSAT, and CALIPSO, to highlight that CAS can have both positive and negative effects on the information content of satellite measurements. This is in sharp contrast to other fields of remote sensing where CAS are usually considered an interference except in those cases when they are the primary subject of study. Our analysis has revealed that in the reflected wavelengths one often sees much further down into the atmosphere, through most cirrus, than one does in the emitted wavelengths. The lower level clouds provide a nice background against which one can track long-range transport of trace gases and aerosols. In addition, differences in trace gas columns estimated over cloudy and adjacent clear pixels can be used to measure boundary layer trace gases. However, in order to take full advantage of these features it will be necessary to greatly advance our understanding of

    Air pollution is one of the main factors that affect the air quality in aircraft cabins, and the use of different air supply modes could influence the distribution of air pollutants in cabins. Based on the traditional ceiling air supply mode used on the B737NG, this study investigated another 3 different kinds of air supply modes for comparison: luggage rack air supply mode, joint mode combining ceiling and luggage rack air supply, and joint mode combining ceiling and individual air supply. Under the above 4 air supply modes, the air velocity, temperature and distribution of air pollutants in a cabin full of passengers were studied using computational fluid dynamics (CFD), and carbon dioxide (CO2) and formaldehyde were selected as 2 kinds of representative air pollutants. The simulation results show that the joint mode combining ceiling and individual air supply can create a more uniform distribution of air velocity and temperature, has a better effect on the removal of CO2 and formaldehyde, and can provide better air quality in cabins than the other 3 modes.

    Tamimi, Abdallah Ibrahim

    Quality management is a fundamental challenge facing businesses. This research attempted to quantify the effect of quality investment on the Cost of Poor Quality (COPQ) in an aerospace company utilizing 3 years of quality data at United Launch Alliance, a Boeing -- Lockheed Martin Joint Venture Company. Statistical analysis tools, like multiple regressions, were used to quantify the relationship between quality investments and COPQ. Strong correlations were evident by the high correlation coefficient R2 and very small p-values in multiple regression analysis. The models in the study helped produce an Excel macro that based on preset constraints, optimized the level of quality spending to minimize COPQ. The study confirmed that as quality investments were increased, the COPQ decreased steadily until a point of diminishing return was reached. The findings may be used to develop an approach to reduce the COPQ and enhance product performance. Achieving superior quality in rocket launching enhances the accuracy, reliability, and mission success of delivering satellites to their precise orbits in pursuit of knowledge, peace, and freedom while assuring safety for the end user.

    This study examined whether individuals with different personality types (i.e., overcontrollers, undercontrollers, resilients) had different friendship quality development throughout adolescence. It also investigated whether personality types were indirectly related to romantic relationship quality in young adulthood, via friendship quality development in adolescence. The study employed six waves of longitudinal questionnaire data from Dutch youths who had a romantic relationship when they were young adults. Two age cohorts were followed, from 12 to 21 years and from 16 to 25 years, respectively. Findings showed that resilients reported higher mean levels of friendship quality during adolescence (i.e., more support from, less negative interaction with and less dominance from their best friend) than both overcontrollers and undercontrollers. Through the mean levels of friendship quality throughout adolescence, resilients indirectly experienced higher romantic relationship quality during young adulthood than both overcontrollers and undercontrollers. Thus, results provide support for a developmental model in which adolescent friendship quality is a mechanism linking personality types with young adulthood romantic relationship quality.

    Purpose The purpose of this paper is to develop a systematic approach to predict service quality dimension's influence on service quality using a novel analysis based on data envelopment and SERVQUAL. Design/methodology/approach To assess hospital service quality in Tehran, expectation and perception of those who received the services were evaluated using SERVQUAL. The hospital service quality dimensions were found by exploratory factor analysis (EFA). To compare customer expectation and perception, perceived service quality index (PSQI) was measured using a new method based on common weights. A novel sensitivity approach was used to test the service quality factor's impact on the PSQI. Findings A new service quality dimension named "trust in services" was found using EFA, which is not an original SERVQUAL factor. The approach was applied to assess the hospital's service quality. Since the PSQI value was 0.76 it showed that improvements are needed to meet customer expectations. The results showed the factor order that affect PSQI. "Trust in services" has the strongest influence on PSQI followed by "tangibles," "assurance," "empathy," and "responsiveness," respectively. Practical implications This work gives managers insight into service quality by following a systematic method; i.e., measuring perceived service quality from the customer viewpoint and service factors' impact on customer perception. Originality/value The procedure helps managers to select the required service quality dimensions which need improvement and predict their effects on customer perception.

    A novel Quality Indicator (QI) and Water Quality Index (WQI) were constructed in the present study for the evaluation of the water quality of a Hydroelectric Plant reservoir in the Amazon area, Brazil, taking into account the specific characteristics of the Amazon area. Factor analyses were applied in order to select the relevant parameters to be included in the construction of both indices. Quality curves for each selected parameter were then created and the constructed QI and WQI were then applied to investigate the water quality at the reservoir. The hydrological cycle was shown by the indices to directly affect reservoir water quality, and the WQI was further useful in identifying anthropogenic impacts in the area, since water sampling stations suffering different anthropogenic impacts were categorized differently, with poorer water quality, than stations near the dam and the environmental preservation area, which suffer significantly less anthropogenic impacts, and were categorized as presenting better water quality. The constructed indices are thus helpful in investigating environmental conditions in areas that show well-defined hydrological cycles, in addition to being valuable tools in the detection of anthropogenic impacts. The statistical techniques applied in the construction of these indices may also be used to construct other indices in different geographical areas, taking into account the specificities for each area.

    Mexico City Metropolitan Area has been the object of several well know intensive campaigns. Since MARI (1991) , IMADA (1997), MCMA 2003 and MILAGRO (2006). The spatial scope of these studies have gone from urban to regional to continental, with the focus on MCMA as an emissions source. During MILAGRO, the influence on MCMA of wildfires and agricultural biomass burning around the megacity was considered. However, around Mexico City a crown of metropolis and middle size cities make a region known as the Central Mexico Regional Crow (CRCM for its acronym in Spanish language) or Central Mexico City Belt. It contains 32 million inhabitants and produces 40% of national gross product. The region undergoes an uncontrolled urban sprawl. Evidence is building-up on complex air pollution transport processes between the air basins within CRCM. However, only MCMA counts with reliable long-term records of criteria pollutants monitoring. Only few intensive campaigns have been done in the air basins surrounding MCMA. ECAIM project has several goals: a) To use ground and satellite observations to assess emissions inventories; b) To use ground and satellite observations to assess the performance of air quality models for the whole region; c) to produce critical levels exceedence maps; d) To produce a preliminary diagnostic of air quality for the CRCM; e) to produce a preliminary estimate of the cost of air pollution within the CRCM. In this work we show the method approach to use the best available information from local AQM networks, field campaigns, satellite observations and modeling to achieve those goals. We show some preliminary results.

    Usually, trees with similar pH values on their bark develop epiphytes of similar species, the acidity to be a factor for growth. The aim of the study was evaluate the air quality through isotope δ13C in order to define the levels of environmental quality in the city of Queretaro, Mexico. In this work were collected at least 4 epiphytes positioned in trees of the species Prosopis Laevigata at 25 sites of Queretaro City. The samples were analyzed for trace elements with an inductively coupled plasma atomic emission spectroscopy (ICP). The collecting took place during dry period, in May and early rain June 2011 period, and on four sectors to identify the spatial distribution of pollution, using isotopic analysis of concentration of δ 13C. According with the results there are significant differences among the species in each of the sampled areas. The 5 February Avenue presented greater diversity and richness of δ13C, followed by those who were surveyed in the proximity of the UAQ and finally in the middle-east area. An average value of δ13C-17.92%, followed by those surveyed in the vicinity of the UAQ that correspond to sector I and II with an concentration of δ13C-17.55% and δ13C-17.22%, and finally the samples collected in trees scattered in the East-Sector II and IV with a value of δ13C-17.02% and δ13C-15.62%, respectively. Also were observed differences between the dry and wet period. It is likely that these results of δ 13C in moist period reflect the drag of the isotopes due to rain events that could mark a trend in the dilution of this element, however there is a trend in terms of abundance and composition of finding more impact in those species sampled in dry period, in May and early June 2011.

    Full Text Available Water quality index (WQI is a dimensionless number that combines multiple water quality factors into a single number by normalizing values to subjective rating curves. Conventionally it has been used for evaluating the quality of water for water resources suchas rivers, streams and lakes, etc. The present work is aimed at assessing the Water Quality Index (W.Q.I ofpond water and the impact of human activities on it. Physicochemical parameters were monitored for the calculation of W.Q.I for the rainy, winter and summer seasons. The parameters namely pH, Total hardness, TDS,Calcium, Chloride, Sulphate, Sodium, Potassium, EC and DO values were within the permissible limits on the other hand total alkalinities and magnesium values were exceeding the permissible limits as prescribed by IndianStandards. However, the W.Q.I values in the present investigation were reported to be 83.43, 76.598 and 91.52 for different season indicating that the pond water quality is very poor and not totally safe for human consumption.

    Coconut skim milk and insoluble protein are 2 major byproducts in the production of virgin coconut oil. Coconut skim milk was homogenized along with insoluble protein and spray dried to obtain a value-added product, namely, coconut protein powder (CPP). This study deals with the storage study of CPP under different conditions (refrigerated [control], ambient and accelerated). CPP samples were withdrawn periodically at designated intervals of 15 d for accelerated and control, and 30 d for ambient condition. CPP stored at different conditions exhibited marginal moisture uptake (by 0.74 % w/w for control, 0.76 % w/w for ambient, and 1.26 % w/w for accelerated condition) and as a result, had very little effect on the functional properties of the powder. Withdrawn CPP was tested for sensory quality aspects and subjected to instrumental analysis as well. Withdrawn CPP was incorporated as a milk substitute in dessert (Kheer). Quantitative descriptive analysis of the powder and product (Kheer) showed no significant difference in attributes of CPP during the storage period of 2 mo. Electronic nose analysis revealed that CPP samples were not much different with respect to aroma pattern matching, respectively.

    Service quality is perceived as an important factor for developing patient's loyalty. The aim of this study was to determine the hospital service quality from the patients' viewpoints and the relative importance of quality dimensions in predicting the patient's loyalty. A cross-sectional study was conducted in 2010. The study sample was composed of 943 patients selected from eight private general hospitals in Tehran. The survey instrument was a questionnaire included 24 items about the service quality and 3 items about the patient's loyalty. Exploratory factor analysis was employed to extracting the dimensions of service quality. Also, regression analysis was performed to determining the relative importance of the service quality dimensions in predicting the patient's loyalty. The mean score of service quality and patient's loyalty was 3.99 and 4.16 out of 5, respectively. About 29% of the loyalty variance was explained by the service quality dimensions. Four quality dimensions (Costing, Process Quality, Interaction Quality and Environment Quality) were found to be key determinants of the patient's loyalty in the private hospitals of Tehran. The patients' experience in relation to the private hospitals' services has strong impact on the outcome variables like willingness to return to the same hospital and reuse its services or recommend them to others. The relationship between the service quality and patient's loyalty proves the strategic importance of improving the service quality for dragging and retaining patients and expanding the market share.

    Full Text Available The research studied evaluative method of physiological properties of three stages of fresh gingers including immature stage, early mature stage and mature stage to be alternative for quality checking of maturity fresh ginger. The classification models were built based on both destructive method and non-destructive methods. The destructive variables were texture parameters, crude fiber and moisture content and the non-destructive variables were specific gravity, color (L*, a*, b*, gloss and light reflection in range 400-700 nm. The results showed that increasing of ginger harvesting date significantly affected physiological properties. The partial least squares discriminant analysis (PLS-DA was performed to create a classifying model for harvesting date of fresh ginger. The 55.56% and 100% best accuracy of classification into three stages of maturity could be achieved by the destructive model and the non-destructive model, respectively. The best applicable variables in building the non-destructive model were light reflection at 420, 450, 490, 530, 570, 590, 680 nm and the specific gravity.

    In this study, soil samples collected from the sides of two streams with high debris flow potential at Shenmu and Fengchiou village in Nantou County, Taiwan, were used for seepage tank tests in the laboratory. While the tests were being conducted, observations were made to investigate the relationships among displacement of the slope, quality of the seepage water and occurrence of mass movement. The results showed that according to the change rate, displacement could be divided into two stages, namely, the initial failure displacement stage and primary failure displacement stage. While the displacement of the slope was in primary failure displacement stages, the probability of slope failure became much higher. Before general slope failure, electrical conductivity (EC) and sulfate ion (SO4 2-) concentration of the seepage water increased significantly. The time when EC of the seepage water started to increase rapidly was much earlier than that when displacement of the slope started to increase significantly. Therefore, from the hazard mitigation view, there will be a longer time for response if EC of the seepage water was monitored.

    Draxl, C.

    2016-12-01

    As variable renewable power penetration levels increase in power systems worldwide, renewable integration studies are crucial to ensure continued economic and reliable operation of the power grid. In this talk we will shed light on requirements for grid integration studies as far as wind and solar energy are concerned. Because wind and solar plants are strongly impacted by weather, high-resolution and high-quality weather data are required to drive power system simulations. Future data sets will have to push limits of numerical weather prediction to yield these high-resolution data sets, and wind data will have to be time-synchronized with solar data. Current wind and solar integration data sets will be presented. The Wind Integration National Dataset (WIND) Toolkit is the largest and most complete grid integration data set publicly available to date. A meteorological data set, wind power production time series, and simulated forecasts created using the Weather Research and Forecasting Model run on a 2-km grid over the continental United States at a 5-min resolution is now publicly available for more than 126,000 land-based and offshore wind power production sites. The Solar Integration National Dataset (SIND) is available as time synchronized with the WIND Toolkit, and will allow for combined wind-solar grid integration studies. The National Solar Radiation Database (NSRDB) is a similar high temporal- and spatial resolution database of 18 years of solar resource data for North America and India. Grid integration studies are also carried out in various countries, which aim at increasing their wind and solar penetration through combined wind and solar integration data sets. We will present a multi-year effort to directly support India's 24x7 energy access goal through a suite of activities aimed at enabling large-scale deployment of clean energy and energy efficiency. Another current effort is the North-American-Renewable-Integration-Study, with the aim of providing

    2015-10-01

    To provide a method to calculate delay cost and examine the relationship between quality and total cost. The total cost including capacity, supply and delay cost for running an interventional radiology suite was calculated. The capacity cost, consisting of labour, lease and overhead costs, was derived based on expenses per unit time. The supply cost was calculated according to actual procedural material use. The delay cost and marginal delay cost derived from queueing models was calculated based on waiting times of inpatients for their procedures. Quality improvement increased patient safety and maintained the outcome. The average daily delay costs were reduced from 1275 € to 294 €, and marginal delay costs from approximately 2000 € to 500 €, respectively. The one-time annual cost saved from the transfer of surgical to radiological procedures was approximately 130,500 €. The yearly delay cost saved was approximately 150,000 €. With increased revenue of 10,000 € in project phase 2, the yearly total cost saved was approximately 290,000 €. Optimal daily capacity of 4.2 procedures was determined. An approach for calculating delay cost toward optimal capacity allocation was presented. An overall quality improvement was achieved at reduced costs. • Improving quality in terms of safety, outcome, efficiency and timeliness reduces cost. • Mismatch of demand and capacity is detrimental to quality and cost. • Full system utilization with random demand results in long waiting periods and increased cost.

    Full Text Available In this paper, we present an empirical study to find the relationship between discretionary accruals quality as well as innate accruals quality and portion of non-executive board of directors, concentration of ownership ratio and board size in Tehran Stock Exchange. The survey selects 118 qualified stocks from this exchange and using a random technique chooses 42 firms. The study implements two linear regression techniques to estimate the first part of the information and then using structural equation modeling examines six hypotheses. Based on the results of this survey we can conclude that an increase on non-executive members positively influences on discretionary accruals quality and negatively influences innate accruals quality. Concentration of ownership ratio positively influences on discretionary accruals quality and negatively impacts on innate accruals quality. Finally, size of board of directors negatively impacts discretionary accruals quality and positively influences on innate accruals quality.

Despite the popularity of PGIS as a body of research, little has been done in the analysis of the quality of PGIS information. The study investigated the use of data quality criteria commonly used in traditional GIS systems and shows that it is possible to apply the criteria used in traditional GIS to PGIS. It provides a starting point for PGIS studies to assess the quality of the product. Notably, this a reflective exercise on one case study, but the methodologies used in this study have been replicated in many others undertaken by Community Based Organisations as well as Non-Governmental Organisations. Therefore the findings are relevant to such projects.

    Participatory GIS (PGIS) has been prescribed by scholars who sought to find a means to enable more equitable access to GIS data, diversifying the types of knowledge captured by a GIS and re-engineering GIS software. The popularity of PGIS is evident in the various studies and contexts in which it has been utilised. These include studies in risk assessment, land administration, resource management, crime mapping and urban design to mention but a few.

    HTTP adaptive streaming is being increasingly deployed by network content providers, such as Netflix and YouTube. By dividing video content into data chunks encoded at different bitrates, a client is able to request the appropriate bitrate for the segment to be played next based on the estimated network conditions. However, this can introduce a number of impairments, including compression artifacts and rebuffering events, which can severely impact an end-user's quality of experience (QoE). We have recently created a new video quality database, which simulates a typical video streaming application, using long video sequences and interesting Netflix content. Going beyond previous efforts, the new database contains highly diverse and contemporary content, and it includes the subjective opinions of a sizable number of human subjects regarding the effects on QoE of both rebuffering and compression distortions. We observed that rebuffering is always obvious and unpleasant to subjects, while bitrate changes may be less obvious due to content-related dependencies. Transient bitrate drops were preferable over rebuffering only on low complexity video content, while consistently low bitrates were poorly tolerated. We evaluated different objective video quality assessment algorithms on our database and found that objective video quality models are unreliable for QoE prediction on videos suffering from both rebuffering events and bitrate changes. This implies the need for more general QoE models that take into account objective quality models, rebuffering-aware information, and memory. The publicly available video content as well as metadata for all of the videos in the new database can be found at http://live.ece.utexas.edu/research/LIVE_NFLXStudy/nflx_index.html.

    Theory of Inventive Problem Solving (TRIZ) is a creative encouraging problem solving method. TRIZ is prepared by Altshuller for product design. Altshuller prepared contradiction matrix and suggestion to solve contradictions usually occur in product design. This paper try to combine TRIZ with quality tools such as Pareto and Fault Tree Analysis (FTA) to solve contradiction in quality improvement problem, neither than product design problem. Pareto used to identify defect priority, FTA used to analysis and identify root cause of defect. When there is contradiction in solving defect causes, TRIZ used to find creative problem solving. As a case study, PT ’X’, a plastic molding manufacturing industry was taken. PT ‘X’ using traditional press machine to produce plastic thread cone. There are 5 defect types that might occur in plastic thread cone production, incomplete form, dirty, mottle, excessive form, rugged. Research about quality improvement effort using DMAIC at PT ‘X’ have been done by Fory Candra. From this research, defect types, priority, root cause from FTA, recommendation from FMEA. In this research, from FTA reviewed, contradictions found among causes troublesome quality improvement efforts. TRIZ used to solve the contradictions and quality improvement effort can be made effectively.

    Full Text Available Pancreatic resection is a standard procedure for the treatment of periampullary tumors. Morbidity and mortality are high, and quality standards are scarce in our setting. International classifications of complications (Clavien-Dindo and those specific for pancreatectomies (ISGPS allow adequate case comparisons. The goals of our work are to describe the morbidity and mortality of 480 pancreatectomies using the international classifications ISGPS and Clavien-Dindo to help establish a quality standard in our setting and to compare the results of CPD with reconstruction by pancreaticogastrostomy (1,55 versus 177 pancreaticojejunostomy. We report 480 resections including 337 duodenopancreatectomies, 116 distal pancreatectomies, 11 total pancreatectomies, 10 central pancreatectomies, and 6 enucleations. Results for duodenopancreatectomy include: 62 % morbidity (Clavien ≥ III 25.9 %, 12.3 % reinterventions, and 3.3 % overall mortality. For reconstruction by pancreaticojejunostomy: 71.2 % morbidity (Clavien ≥ III 34.4 %, 17.5 % reinterventions, and 3.3 % mortality. For reconstruction by pancreaticogastrostomy: 51 % morbidity (Clavien ≥ III 15.4%, 6.4 % reinterventions, and 3.2 % mortality. Differences are significant except for mortality. We conclude that our series meets quality criteria as compared to other groups. Reconstruction with pancreaticogastrostomy significantly reduces complication number and severity, as well as pancreatic fistula and reintervention rates.

    To provide a method to calculate delay cost and examine the relationship between quality and total cost. The total cost including capacity, supply and delay cost for running an interventional radiology suite was calculated. The capacity cost, consisting of labour, lease and overhead costs, was derived based on expenses per unit time. The supply cost was calculated according to actual procedural material use. The delay cost and marginal delay cost derived from queueing models was calculated based on waiting times of inpatients for their procedures. Quality improvement increased patient safety and maintained the outcome. The average daily delay costs were reduced from 1275 EUR to 294 EUR, and marginal delay costs from approximately 2000 EUR to 500 EUR, respectively. The one-time annual cost saved from the transfer of surgical to radiological procedures was approximately 130,500 EUR. The yearly delay cost saved was approximately 150,000 EUR. With increased revenue of 10,000 EUR in project phase 2, the yearly total cost saved was approximately 290,000 EUR. Optimal daily capacity of 4.2 procedures was determined. An approach for calculating delay cost toward optimal capacity allocation was presented. An overall quality improvement was achieved at reduced costs. (orig.)

    China is undergoing rapid urbanization because of unprecedented economic growth. As a result, many cities suffer from air pollution. Two-thirds of China's cities have not attained the ambient air quality standards applicable to urban residential areas (Grade II). Particulate matter (PM), rather than sulfur dioxide (SO2), is the major pollutant reflecting the shift from coal burning to mixed source pollution. In 2002, 63.2 and 22.4% of the monitored cities have PM and SO2 concentrations exceeding the Grade II standard, respectively. Nitrogen oxides (NOx) concentration kept a relatively stable level near the Grade II standard in the last decade and had an increasing potential in recent years because of the rapid motorization. In general, the air pollutants emission did not increase as quickly as the economic growth and energy consumption, and air quality in Chinese cities has improved to some extent. Beijing, a typical representative of rapidly developing cities, is an example to illustrate the possible options for urban air pollution control. Beijing's case provides hope that the challenges associated with improving air quality can be met during a period of explosive development and motorization.

    Ideally, quality is designed into software, just as quality is designed into hardware. However, when dealing with legacy systems, demonstrating that the software meets required quality standards may be difficult to achieve. As the need to demonstrate the quality of existing software was recognized at Los Alamos National Laboratory (LANL), an effort was initiated to uncover and demonstrate that legacy software met the required quality standards. This effort led to the development of a reverse engineering approach referred to as software archaeology. This paper documents the software archaeology approaches used at LANL to document legacy software systems. A case study for the Robotic Integrated Packaging System (RIPS) software is included.

    Perceived service quality is the most important predictor of patient satisfaction. The purpose of this study was to investigate the impact of the service quality on the overall satisfaction of patients in private hospitals of Tehran, Iran. This cross-sectional study was conducted in the year 2010. The study's sample consisted of 969 patients who were recruited from eight private general hospitals in Tehran, Iran using consecutive sampling. A questionnaire was used for data collection; contacting 21 items (17 items about service quality and 4 items about overall satisfaction) and its validity and reliability were confirmed. Data analysis was performed using t-test, ANOVA and multivariate regression. this study found a strong relationship between service quality and patient satisfaction. About 45% of the variance in overall satisfaction was explained by four dimensions of perceived service quality. The cost of services, the quality of the process and the quality of interaction had the greatest effects on the overall satisfaction of patients, but not found a significant effect on the quality of the physical environment on patient satisfaction. Constructs related to costs, delivery of service and interpersonal aspect of care had the most positive impact on overall satisfaction of patients. Managers and owners of private hospitals should set reasonable prices compared to the quality of service. In terms of process quality, waiting time for visits, admissions, and surgeries must be declined and services provided at the fastest possible time. It should be emphasized to strengthen of interpersonal aspects of care and communication skills of care providers.

    2014-01-01

    To describe the evolution of methods and share lessons learned from conducting multi-state studies with Medicaid Medical Directors (MMD) using state administrative data. There was a great need for these studies, but also much to be learned about conducting network-based research and ensuring comparability of results. This was a network-level case study. The findings were drawn from the experience developing and executing network analyses with the MMDs, as well as from participant feedback on lessons learned. For the latter, nine interviews with MMD project leads, state data analysts, and outside researchers involved with the projects were conducted. Interviews were transcribed, coded and analyzed using NVivo 10.0 analytic software. MMD study methodology involved many steps: developing research questions, defining data specifications, organizing an aggregated data collection spreadsheet form, assuring quality through review, and analyzing and reporting state data at the national level. State analysts extracted the data from their state Medicaid administrative (claims) databases (and sometimes other datasets). Analysis at the national level aggregated state data overall, by demographics and other sub groups, and displayed descriptive statistics and cross-tabs. Projects in the MMD multi-state network address high-priority clinical issues in Medicaid and impact quality of care through sharing of data and policies among states. Further, these studies contribute not only to high-quality, cost-effective health care for Medicaid beneficiaries, but also add to our knowledge of network-based research. Continuation of these studies requires funding for a permanent research infrastructure nationally, as well as at the state-level to strengthen capacity.

    Objective The main objective of this study was to determine the relationship between the characteristics of nurses' work environments in hospitals in the Spanish National Health System (SNHS) with nurse reported quality of care, and how care was provided by using different shifts schemes. The study also examined the relationship between job satisfaction, burnout, sleep quality and daytime drowsiness of nurses and shift work. Methods This was a multicentre, observational, descriptive, cross-sectional study, centred on a self-administered questionnaire. The study was conducted in seven SNHS hospitals of different sizes. We recruited 635 registered nurses who worked on day, night and rotational shifts on surgical, medical and critical care units. Their average age was 41.1 years, their average work experience was 16.4 years and 90% worked full time. A descriptive and bivariate analysis was carried out to study the relationship between work environment, quality and safety care, and sleep quality of nurses working different shift patterns. Results 65.4% (410) of nurses worked on a rotating shift. The Practice Environment Scale of the Nursing Work Index classification ranked 20% (95) as favourable, showing differences in nurse manager ability, leadership and support between shifts (p=0.003). 46.6% (286) were sure that patients could manage their self-care after discharge, but there were differences between shifts (p=0.035). 33.1% (201) agreed with information being lost in the shift change, showing differences between shifts (p=0.002). The Pittsburgh Sleep Quality Index reflected an average of 6.8 (SD 3.39), with differences between shifts (p=0.017). Conclusions Nursing requires shift work, and the results showed that the rotating shift was the most common. Rotating shift nurses reported worse perception in organisational and work environmental factors. Rotating and night shift nurses were less confident about patients' competence of self-care after discharge. The

    The goal of mammography is to provide contrast between a lesion that is possible residing within the breast and normal surrounding tissue. Quality control is essential for maintaining the contrast imaging performance of a mammography system and incorporate tests that are relevant in that they are predictive of future degradation of contrast imaging performance. These tests will also be done at frequency that is high enough to intercept most drifts in quality imaging or performance before they become diagnostically significant. The quality control study has as objective to describe the results of the assessment of quality imaging elements (film optical density, contrast (density difference), uniformity, resolution and noise) of 62 mammography departments without quality control program and comparison these results with a mammography reference department with a quality control program. When comparing the results they allow seeing the clinical utility of to have a quality control program to reduce the errors of mammography interpretation. (Author)

    Successful quality improvement (QI) requires a supportive context. The goal was to determine whether a structured curriculum could help QI teams improve the context supporting their QI work. An exploratory field study was conducted of 43 teams participating in a neonatal intensive care unit QI collaborative. Using a curriculum based on the Model for Understanding Success in Quality, teams identified gaps in their context and tested interventions to modify context. Surveys and self-reflective journals were analyzed to understand how teams developed changes to modify context. More than half (55%) targeted contextual improvements within the microsystem, focusing on motivation and culture. "Information sharing" interventions to communicate information about the project as a strategy to engage more staff were the most common interventions tested. Further study is needed to determine if efforts to modify context consistently lead to greater outcome improvements.

    The concept of Quality of Life is becoming an increasingly important measure of the impact of psychiatric disorders and is now recognized as useful in the healthcare evaluation of patients with psychiatric disorders. The aim of this review was to document and analyze the research data on quality of life in Nigerian patients with psychiatric disorders. The electronic databases, Medline and Pubmed were searched for published articles on quality of life in Nigerian patients with psychiatric disorders. A total of 6 studies met the inclusion criteria. All the studies employed the generic World Health Organization Quality of Life Scale - Brief version, which is the only quality of life instrument whose psychometric properties have been evaluated among Nigerian patients with psychiatric disorders. Some of the studies revealed that quality of life was significantly associated with socio demographic factors such marital and employment status and social support. Poor quality of life was reported to be associated with illness related factors such as co morbid medical problems, presence of anxiety and depressive symptoms and non adherence to medications. All the studies with the exception of two were conducted in centers located in South-western Nigeria. Quality of life in Nigerian patients suffering from psychiatric disorders is under-researched. There is need for more studies to prospectively investigate quality of life and associated factors among Nigerian patients with psychiatric disorders.

    2014-05-01

    An Atmospheric Modelling System has been set up at International Centre for Integrated Mountain Development (ICIMOD) for the assessment of Air Quality across the Himalaya mountain ranges. The Weather Research and Forecasting (WRF) model version 3.5 has been implemented over the regional domain, stretching across 4995 x 4455 km2 centred at Ichhyakamana , the ICIMOD newly setting-up mountain-peak station (1860 m) in central Nepal, and covering terrains from sea-level to the Everest (8848 m). Simulation is carried out for the winter time period, i.e. December 2012 to February 2013, when there was an intensive field campaign SusKat, where at least 7 super stations were collecting meteorology and chemical parameters on various sites. The very complex terrain requires a high horizontal resolution (1 × 1 km2), which is achieved by nesting the domain of interest, e.g. Kathmandu Valley, into 3 coarser ones (27, 9, 3 km resolution). Model validation is performed against the field data as well as satellite data, and the challenge of capturing the necessary atmospheric processes is discussed, before moving forward with the fully coupled chemistry module (WRF-Chem), having local and regional emission databases as input. The effort aims at finding a better understanding of the atmospheric processes and air quality impact on the mountain population, as well as the impact of the long-range transport, particularly of Black Carbon aerosol deposition, to the radiative budget over the Himalayan glaciers. The higher rate of snowcap melting, and shrinkage of permafrost as noticed by glaciologists is a concern. Better prediction will supply crucial information to form the proper mitigation and adaptation strategies for saving people lives across the Himalayas in the changing climate.

    The use of two-dimensional (2D) images is consistently used to prepare anatomy students for handling real specimen. This study examined whether the quality of 2D images is a critical component in anatomy learning. The visual clarity and consistency of 2D anatomical images was systematically manipulated to produce low-quality and high-quality images of the human hand and human eye. On day 0, participants learned about each anatomical specimen from paper booklets using either low-quality or high-quality images, and then completed a comprehension test using either 2D images or three-dimensional (3D) cadaveric specimens. On day 1, participants relearned each booklet, and on day 2 participants completed a final comprehension test using either 2D images or 3D cadaveric specimens. The effect of image quality on learning varied according to anatomical content, with high-quality images having a greater effect on improving learning of hand anatomy than eye anatomy (high-quality vs. low-quality for hand anatomy P = 0.018; high-quality vs. low-quality for eye anatomy P = 0.247). Also, the benefit of high-quality images on hand anatomy learning was restricted to performance on short-answer (SA) questions immediately after learning (high-quality vs. low-quality on SA questions P = 0.018), but did not apply to performance on multiple-choice (MC) questions (high-quality vs. low-quality on MC questions P = 0.109) or after participants had an additional learning opportunity (24 hours later) with anatomy content (high vs. low on SA questions P = 0.643). This study underscores the limited impact of image quality on anatomy learning, and questions whether investment in enhancing image quality of learning aids significantly promotes knowledge development.

    Full Text Available Water is a prime requirement for all the living and non-living processes. On the earth, 71% is water but the availability of useable fresh water for drinking and other purposes is about 2.8%. Out of this 2.8 % fresh water, the share of groundwater is only 0.6% that makes it more pertinent to conservation, preservation, and management. The urbanization, industrialization, and intensive agricultural practices have put further pressure on the available fresh water. The modern techniques like space technology, GIS and GPS have great utility in mapping, monitoring, planning and management of water resources. The temporal satellite data in different spectral bands and on different spatial resolutions make the remote sensing satellite data highly useful for mapping and monitoring of an area. The geographical information system (GIS has the capability to store, retrieve, edit and represent the data in informative way. The global positioning system (GPS gives the real time geo-coordinates, path and altitude of desired object or terrain. Thus, the geoinformatics have huge potential for solving the problems of groundwater availability and quality, and there is a need to harness the potential of these techniques for societal benefits to provide water everyone.

    Miranda, Rommel Joseph

    By employing qualitative methods, this study sought to determine the perceptions that urban stakeholders hold about what characteristics should distinguish a high school science teacher whom they would consider to demonstrate high quality in science teaching. A maximum variation sample of six science teachers, three school administrators, six parents and six students from a large urban public school district were interviewed using semi-structured, in-depth interview techniques. From these data, a list of observable characteristics which urban stakeholders hold as evidence of high quality in science teaching was generated. Observational techniques were utilized to determine the extent to which six urban high school science teachers, who meet the NCLB Act criteria for being "highly qualified", actually possessed the characteristics which these stakeholders hold as evidence of high quality in science teaching. Constant comparative analysis was used to analyze the data set. The findings suggest that urban stakeholders perceive that a high school science teacher who demonstrates high quality in science teaching should be knowledgeable about their subject matter, their student population, and should be resourceful; should possess an academic background in science and professional experience in science teaching; should exhibit professionalism, a passion for science and teaching, and a dedication to teaching and student learning; should be skillful in planning and preparing science lessons and in organizing the classroom, in presenting the subject matter to students, in conducting a variety of hands-on activities, and in managing a classroom; and should assess whether students complete class goals and objectives, and provide feedback about grades for students promptly. The findings further reveal that some of the urban high school science teachers who were deemed to be "highly qualified", as defined by the NCLB Act, engaged in practices that threatened quality in science

    This paper reports a small-scale pilot study on the expectations on interpretation quality from employers. It is based on a questionnaire, in which eight criteria of quality and two open-ended questions are listed. The participants were asked to rate the eight criteria. The results suggest that different employer groups share similar expectations on high-quality interpretation, but the value they attach to each criterion varies according to their affiliations. Employers sometimes mix interpretation quality with their personal tastes and feelings.

    The development of medicinal products is subject to quality standards aimed at guaranteeing that database contents accurately reflect the source documents. Paradoxically, these standards hardly address the quality of the source data itself. The objective of this work was to propose recommendations to improve data quality in three fields (pharmacovigilance, pharmacoepidemiology and clinical studies). The analysis was focused on the data and on the critical stages presenting critical quality problems, for which the current guidelines are insufficiently detailed, unsuitable and/or poorly applied. Finally, recommendations have been proposed, mainly focused on the origin of the data and its transcription.

    Full Text Available Nowadays, Consumer’s expectation has soared which brought about a gap between the discerned quality and actual quality of some American-made merchandises. On the other hand, considerable domestic and international market shares of Japanese products derived from the narrowed gap in quality of firms. In some industries, Japanese fine quality products have now replaced the United States as “number one” in such industries. For several years, Total Quality Management (TQM has been implemented in Western Europe since its earlier origin in Japan. In fact, the influence of TQM on a number of notable successful manufacturing organizations is inevitable, together with some less revealed failures. This research describes the details of management in Iran and compare its criteria’s with developed countries such as Japan. To some extent, this study is destined to present some solutions to improve the management and quality in industrial productions.

    Full Text Available Business process modeling is one of the first steps towards achieving organizational goals. This is why business process modeling quality is an essential aspect for the development and technical support of any company. This work focuses on the quality of business process models at a conceptual l evel (design and evaluation. In the literature there are works that propose practical guidelines for modeling, while others focus on quality metrics that allow the evaluation of the models. In this paper we use practical guidelines during the modeling phase of a business process for postgraduate studies. We applied a set of quality metrics and compare the results with those obtained from a similar model that did not use guidelines. The results provide support for the use of guidelines as a way for business process modeling quality improvement, and the practical utility of quality metrics in their evaluation.

    Full Text Available Background: Hospital services quality plays an increasingly important role in today’s competitive environment. This study aimed to evaluate causal effects of different healthcare quality aspects on quality of services perceived by patients in hospitals affiliated by Shahid Sadoughi University of Medical Sciences using DEMATEL and TOPSIS techniques in 2014. Method: Through literature review and expert opinions, different service quality dimensions in under study hospitals were identified and required data were gathered. In the next step, DEMATEL technique was applied to determine cause and effect relationships between identified quality aspects and quality perceived by service recipients. Also to rank dimensions according to their priorities, TOPSIS method was used. Given the literature review, six quality dimensions including responsiveness, assurance, security, tangibility, communication and patient centeredness were identified. Result: Results obtained from DEMATEL technique introduced patient security as an influential aspect which was ranked in the sixth place in terms of importance. Conclusion: The prioritization of quality dimensions along with their causal effects provides a beneficial insight for hospital managers to effectively plan and make improvement decisions. It is suggested that considering a remarkable impact of security on patients’ perception toward quality of care, this aspect should be regarded in decision makers’ programs with a greater emphasis.

    The focus of the current investigations was to apply quality by design (QbD) approach to the development of dispersible tablets. Critical material and process parameters are linked to the critical quality attributes of the product. Variability is reduced by product and process understanding which translates into quality improvement, risk reduction and productivity enhancement. The risk management approach further leads to better understanding of the risks, ways to mitigate them and control strategy is proposed commensurate with the level of the risk. Design space in combination with pharmaceutical quality management system provide for flexible regulatory approaches with opportunity for continuous improvement that benefit patient and manufacturer alike. The development of dispersible tablet was proposed in the current study through a QbD paradigm for a better patient compliance and product quality. The quality target product profile of a model biopharmaceutical class II drug was identified. Initial risk analysis led to the identification of the critical quality attributes. Physicochemical characterization and compatibility studies of the drug with commonly used excipients were performed. Experiments were designed with focus on critical material and process attributes. Design space was identified and risk factors for all the possible failure modes were below critical levels after the implementation of control strategy. Compliance to the design space provides an opportunity to release batches in a real time. In conclusion, QbD tools together with risk and quality management tools provided an effective and efficient paradigm to build the quality into dispersible tablet.

    The high competitiveness makes the quest for production cost reduction a constant in the market, but it is necessary to reduce costs without compromising quality. When a product is in the manufacturing and this has to be scraped, we have more cost than the raw material used, it is necessary to consider the manpower and operations, thus to calculate the cost added to the product. Continuous quality improvement is a key factor in the strategy for competitiveness. Quality cost is one tool, among many others, that can help in continuous quality improvement. Properly applying quality cost techniques is critical to these efforts. Initially, a complete quality cost study could provide awareness and guidance to a steering committee on what cross-discipline teams and improvement projects should be started. The cross discipline teams also can use quality cost special studies to help in focusing efforts. In this paper cost of poor quality analysis has been done using different techniques which are currently applying in automobile industry to assess quality cost.

    2017-02-01

    Prior reviews of geriatrics curricula for internal medicine (IM) and family medicine (FM) residents have not evaluated study quality or assessed learning objectives or specific IM or FM competencies. This review of geriatrics curricula for IM and FM residents seeks to answer 3 questions: (1) What types of learning outcomes were measured? (2) How were learning outcomes measured? and (3) What was the quality of the studies? We evaluated geriatrics curricula that reported learning objectives or competencies, teaching methods, and learning outcomes, and those that used a comparative design. We searched PubMed and 4 other data sets from 2003-2015, and assessed learning outcomes, outcome measures, and the quality of studies using the Medical Education Research Study Quality Instrument (MERSQI) and Best Evidence Medical Education (BEME) methods. Fourteen studies met inclusion criteria. Most curricula were intended for IM residents in the inpatient setting; only 1 was solely dedicated to FM residents. Median duration was 1 month, and minimum geriatrics competencies covered were 4. Learning outcomes ranged from Kirkpatrick levels 1 to 3. Studies that reported effect size showed a considerable impact on attitudes and knowledge, mainly via pretests and posttests. The mean MERSQI score was 10.5 (range, 8.5-13) on a scale of 5 (lowest quality) to 18 (highest quality). Few geriatrics curricula for IM and FM residents that included learning outcome assessments were published recently. Overall, changes in attitudes and knowledge were sizeable, but reporting was limited to low to moderate Kirkpatrick levels. Study quality was moderate.

  8. Development of a Fuzzy Water Quality Index (FWQI – Case study: Saveh Plain

    Full Text Available Introduction: Groundwater resources are the main source of fresh water in many parts of Iran. Groundwater resources are limited in quantity and recently due to increase of withdrawal, these resources are facing great stress. Considering groundwater resources scarcity, maintaining the quality of them are vital. Traditional methods to evaluate water quality insist on determining water quality parameter and comparison between them and available standards. The decisions in these methods rely on just specific parameters, in order to overcome this issue, water quality indices (WQIs are developed. Water quality indexes include a range of water quality parameters and using mathematical operation represent an index to classify water quality. Applying the classic WQI will cause deterministic and inflexible classifications associated with uncertainties and inaccuracies in knowledge and data. To overcome this shortcoming, using the fuzzy logic in water resources problems under uncertainty is highly recommended. In this paper, two approaches are adopted to assess the water quality status of the groundwater resources of a case study. The first approach determined the classification of water samples, whilst the second one focused on uncertainty of classification analysis with the aid of fuzzy logic. In this regard, the paper emphasizes on possibility of water quality assessment by developing a fuzzy-based quality index even if required parameters are inadequate. Materials and Methods: The case study is located in the northwest of Markazi province, Saveh Plain covers an area of 3245 km2 and lies between 34º45′-35º03′N latitude and 50º08′-50º50′E longitudes. The average height of the study area is 1108 meter above mean sea level. The average precipitation amount is 213 mm while the mean annual temperature is 18.2oC. To provide a composite influence from individual water quality parameters on total water quality, WQI is employed. In other words, WQI

    The Kolong River of Nagaon district, Assam has been facing serious degradation leading to its current moribund condition due to a drastic human intervention in the form of an embankment put across it near its take-off point from the Brahmaputra River in the year 1964. The blockage of the river flow was adopted as a flood control measure to protect its riparian areas, especially the Nagaon town, from flood hazard. The river, once a blooming distributary of the mighty Brahmaputra, had high navigability and rich riparian biodiversity with a well established agriculturally productive watershed. However, the present status of Kolong River is highly wretched as a consequence of the post-dam effects thus leaving it as stagnant pools of polluted water with negligible socio-economic and ecological value. The Central Pollution Control Board, in one of its report has placed the Kolong River among 275 most polluted rivers of India. Thus, this study is conducted to analyze the seasonal water quality status of the Kolong River in terms of water quality index (WQI). The WQI scores shows very poor to unsuitable quality of water samples in almost all the seven sampling sites along the Kolong River. The water quality is found to be most deteriorated during monsoon season with an average WQI value of 122.47 as compared to pre-monsoon and post-monsoon season having average WQI value of 85.73 and 80.75, respectively. Out of the seven sampling sites, Hatimura site (S1) and Nagaon Town site (S4) are observed to be the most polluted sites.

    Full Text Available Purpose: E-Government, as a new bond linking the government and the public, has gradually become the focus of innovation in government services. The paper focuses on the e-Government service quality issues from the perspective of users. Design/methodology/approach: From the aspects of online service quality perception and offline service quality perception, based on IS Success model and SERQUAL model, e-Government Services Quality model has been set up with information quality, system quality and service quality as key factors. Then, the survey method was applied to collect data and then to test the model. Findings: It was found that users’ perception of offline service quality has a significant effect on improving their perception of online service quality, and online service quality perception has a significant effect on public satisfaction of e-Government services; information clarity, system security and stability, interactive services and “one-stop” services all have a significant effect on public satisfaction of e-Government services. However, offline service quality perception has certain positive effect on public satisfaction of e-Government services but not dramatically. Research limitations/implications: Mobile e-Government as an important direction of the development of e-Government, in the future, we will study more about mobile e-Government services channels. Originality/value: This study further develops the theory of information system service quality, and also provides a theoretical reference for government departments. On the one hand, based on the characteristics of e-government system, information quality, system quality and service quality in the previous system service model are further discussed; on the other hand, both online and offline services are taken into consideration in the information system service model, thus establishing the e-government services quality model and making an in-depth study of the

    Classroom ventilation rates often do not meet building standards, although it is considered to be important to improve indoor air quality. Poor indoor air quality is thought to influence both children's health and performance. Poor ventilation in The Netherlands most often occurs in the heating season. To improve classroom ventilation a tailor made mechanical ventilation device was developed to improve outdoor air supply. This paper studies the effect of this intervention. The FRESH study (Forced-ventilation Related Environmental School Health) was designed to investigate the effect of a CO2 controlled mechanical ventilation intervention on classroom CO2 levels using a longitudinal cross-over design. Target CO2 concentrations were 800 and 1200 parts per million (ppm), respectively. The study included 18 classrooms from 17 schools from the north-eastern part of The Netherlands, 12 experimental classrooms and 6 control classrooms. Data on indoor levels of CO2, temperature and relative humidity were collected during three consecutive weeks per school during the heating seasons of 2010-2012. Associations between the intervention and weekly average indoor CO2 levels, classroom temperature and relative humidity were assessed by means of mixed models with random school-effects. At baseline, mean CO2 concentration for all schools was 1335 ppm (range: 763-2000 ppm). The intervention was able to significantly decrease CO2 levels in the intervention classrooms (F (2,10) = 17.59, p < 0.001), with a mean decrease of 491 ppm. With the target set at 800 ppm, mean CO2 was 841 ppm (range: 743-925 ppm); with the target set at 1200 ppm, mean CO2 was 975 ppm (range: 887-1077 ppm). Although the device was not capable of precisely achieving the two predefined levels of CO2, our study showed that classroom CO2 levels can be reduced by intervening on classroom ventilation using a CO2 controlled mechanical ventilation system.

    The merits of mixed public and private health systems are debated. Although private providers have become increasingly important in the Indonesian health system, there is no comprehensive assessment of the quality of private facilities. This study examined the quality of physical resources of public and private facilities in Indonesia from 1993 to 2007. Data from the Indonesian Family Life Surveys in 1993, 1997, 2000 and 2007 were used to evaluate trends in the quality of physical resources for public and private facilities, stratified by urban/rural areas and Java-Bali/outer Java-Bali regions. The quality of six categories of resources was measured using an adapted MEASURE Evaluation framework. Overall quality was moderate, but higher in public than in private health facilities in all years regardless of the region. The higher proportion of nurses and midwives in private practice was a determinant of scope of services and facilities available. There was little improvement in quality of physical resources following decentralization. Despite significant increases in public investment in health between 2000 and 2006 and the potential benefits of decentralization (2001), the quality of both public and private health facilities in Indonesia did not improve significantly between 1993 and 2007. As consumers commonly believe the quality is better in private facilities and are increasingly using them, it is essential to improve quality in both private and public facilities. Implementation of minimum standards and effective partnerships with private practice are considered important.

To understand the general water quality situation, the time series data of selected water quality parameters were analyzed in an urban river in Peninsular Malaysia. In this regard, the stations were selected from the main stem of the river as well as from the side channel. The stations located at the main stem of the river are less polluted than that in the side channel. Water Quality Index scores indicated that the side channel station is the most polluted, breaching the Class IV water quality criteria threshold during the monitoring period, followed by stations at the river mouth and the main channel. The effect of immediate anthropogenic waste input is also evident at the side channel station. The Organic Pollution Index of side channel station is (14.99) 3 times higher than at stations at river mouth (4.11) and 6 times higher than at the main channel (2.57). The two-way ANOVA showed significant difference among different stations. Further, the factor analysis on water quality parameters yielded two significant factors. They discriminated the stations into two groups. The land-use land cover classification of the study area shows that the region near the sampling sites is dominated by urban settlements (33.23 %) and this can contribute significantly to the deterioration of ambient river water quality. The present study estimated the water quality condition and response in the river and the study can be an immediate yardstick for base lining river water quality, and a basis for future water quality modeling studies in the region.

    Full Text Available Abstract Background Medical education can affect medical students’ physical and mental health as well as their quality of life. The aim of this study was to assess medical students’ perceptions of their quality of life and its relationship with medical education. Methods First- to sixth-year students from six Brazilian medical schools were interviewed using focus groups to explore what medical student’s lives are like, factors related to increases and decreases of their quality of life during medical school, and how they deal with the difficulties in their training. Results Students reported a variety of difficulties and crises during medical school. Factors that were reported to decrease their quality of life included competition, unprepared teachers, excessive activities, and medical school schedules that demanded exclusive dedication. Contact with pain, death and suffering and harsh social realities influence their quality of life, as well as frustrations with the program and insecurity regarding their professional future. The scarcity of time for studying, leisure activities, relationships, and rest was considered the main factor of influence. Among factors that increase quality of life are good teachers, classes with good didactic approaches, active learning methodologies, contact with patients, and efficient time management. Students also reported that meaningful relationships with family members, friends, or teachers increase their quality of life. Conclusion Quality of teachers, curricula, healthy lifestyles related to eating habits, sleep, and physical activity modify medical students’ quality of life. Lack of time due to medical school obligations was a major impact factor. Students affirm their quality of life is influenced by their medical school experiences, but they also reframe their difficulties, herein represented by their poor quality of life, understood as necessary and inherent to the process of becoming doctors.

    Full Text Available Problem statement: The rapid growth of urbanization has led to degradation of quality of life in many developing countries. The qualitative approach towards development concepts provided background for studying the object of quality of life. This concept was declared by Raymond Bauer in 1966 in response to the increase of urban crisis. Today, quality of life refers to the capacity of a place for living life. Approach: The present study aims to analyze quality of life by concentrating on the socio-economic, physical-environmental and mental indexes. The indexes were selected with respect to their importance by conducting a careful examination. The comparative analysis was applied based on hierarchical weighting. Observation and completing questionnaire have been two important tools in this research. Results: The results revealed that there are significant socio-economic gap among the different neighborhoods of the town. The mean of urban quality of life is 8.517 which show a moderate level of quality of life according to the research classification. Conclusion: The research came to conclusion that the different neighborhoods of the town showed different level of quality of life which it leads to socio-economic disparities among the urban zones. So the priority of planning should concentrate on the areas where deprivation decreased the level of quality of life.

    Full Text Available Abstract Background Changes in world assumptions are a fundamental concept within theories that explain posttraumatic stress disorder. The objective of the present study was to gain a greater understanding of how changes in world assumptions are related to quality of life and posttraumatic stress symptoms after a natural disaster. Methods A longitudinal study of 574 Norwegian adults who survived the Southeast Asian tsunami in 2004 was undertaken. Multilevel analyses were used to identify which factors at six months post-tsunami predicted quality of life and posttraumatic stress symptoms two years post-tsunami. Results Good quality of life and posttraumatic stress symptoms were negatively related. However, major differences in the predictors of these outcomes were found. Females reported significantly higher quality of life and more posttraumatic stress than men. The association between level of exposure to the tsunami and quality of life seemed to be mediated by posttraumatic stress. Negative perceived changes in the assumption “the world is just” were related to adverse outcome in both quality of life and posttraumatic stress. Positive perceived changes in the assumptions “life is meaningful” and “feeling that I am a valuable human” were associated with higher levels of quality of life but not with posttraumatic stress. Conclusions Quality of life and posttraumatic stress symptoms demonstrate differences in their etiology. World assumptions may be less specifically related to posttraumatic stress than has been postulated in some cognitive theories.

    Police officers are exposed to traumatic and life-threatening events, which may lead to sleep problems. Prior studies of police officers have found them to have poor sleep quality and reduced sleep time. This study examined associations between traumatic events and sleep quality. Participants were 372 police officers from the Buffalo Cardio-metabolic Occupational Police Stress (BCOPS) Study. Police incidents were measured by the Police Incident Survey; sleep quality and quantity were derived from the Pittsburgh Sleep Quality Index (PSQI). Analysis of covariance (ANCOVA) was used to examine mean PSQI scores across categories of traumatic event frequency. Models were adjusted for age, education and ethnicity and stratified by sex and workload. In men, significant associations were found for the 'shooting of another officer' and sleep quality (p-value = 0.024) and sleep disturbances (p-value = 0.022). In women, seeing more 'abused children' was associated with poorer sleep quality (p-value = 0.050); increasing frequency of 'seeing victims of a serious traffic accident' was associated with shorter sleep duration (p-value = 0.032). Increased frequency of 'seeing dead bodies' was associated with poorer sleep quality (p-value = 0.040) and shorter sleep duration (p-value = 0.048). Among women with a high workload, a significant inverse association was found between 'seeing serious traffic accident victims' and global sleep quality (p-value = 0.031). In conclusion, a significant inverse association between frequency of select traumatic events and sleep quality was found in male and female police officers. The significant events differed by sex. Future research could examine longitudinal associations between career-long traumatic event exposures and sleep quality and how these associations differ by sex.

    Full Text Available Abstract Background Sleep is an important physiological process for humans. University students in most resource limited countries often report poor sleep quality due to changing social opportunities and increasing academic demands. However, sleep quality among university students has not been studied in Ethiopia. Thus, this study assessed sleep quality and its demographic and psychological correlates among university students. Methods A cross-sectional survey was conducted in two universities in Ethiopia. Multistage sampling procedures were used to enroll 2,817 students into the study. A self-administered structured questionnaire including the Pittsburgh Sleep Quality Index (PSQI, the Depression Anxiety Stress Scale-21, the Perceived Stress Scale (PSS and selected modules of the World Health Organization STEPS instrument was used for the study. This research included 2,551 students. Frequency, median, mean with standard deviation and 95% confidence interval were used to characterize sleep quality and other variables. Analysis of variance and binary logistic regression procedures were also used. Result The prevalence of poor sleep quality (total PSQI score > 5 was 55.8% (1,424. Female students (adjusted odds ratio (AOR 1.23; 95% CI: 1.00, 1.57, second year (AOR 2.91; 95% CI: 2.1, 4.02 and third year students (AOR 2.25; 95% CI 1.62, 3.12 had statistically significant higher odds of poor sleep quality. Perceived stress level and symptoms of depression and anxiety were strongly associated with sleep quality. Conclusion A substantial proportion of university students are affected by poor sleep quality. If our results are confirmed in prospective studies, health promotion and educational programs for students should emphasize the importance of sleep and mental health.

    Bioindicators are organisms used to identify and quantify air pollution effects e.g. on plants. For this purpose specific plants are used in standardised methods, to give proof of a reaction e.g. caused by ozone or to give proof of accumulation of organic or inorganic compounds. In the following paper case studies are described for the use of bioindicators. The identification respectively the monitoring of pollutants is usually carried out by active or passive bio-monitoring methods. In the first case study, the planar distribution of heavy metal pollution (by the example of lead, cadmium, zinc) in moss in Germany will be presented. In the second study standardised green cabbage was used as biomonitor and surrogat to monitor the contamination of garden vegetables by polychlorinated dioxins/furans in the vicinity of two metal recycling plants before and after the installation of emission reduction techniques. The results demonstrate that after installing the new techniques a remarkable reduction of PCDD/F content in the bio-indicator green cabbage could be shown. In the third case, the possibility to identify the cause of contamination of heavy metals in the environment by using the grass culture will be described. (orig.)

    To determine the relationship between return on investment (ROI) and quality of study methodology in workplace health promotion programs. Data were obtained through a systematic literature search of National Health Service Economic Evaluation Database (NHS EED), Database of Abstracts of Reviews of Effects (DARE), Health Technology Database (HTA), Cost Effectiveness Analysis (CEA) Registry, EconLit, PubMed, Embase, Wiley, and Scopus. Included were articles written in English or German reporting cost(s) and benefit(s) and single or multicomponent health promotion programs on working adults. Return-to-work and workplace injury prevention studies were excluded. Methodological quality was graded using British Medical Journal Economic Evaluation Working Party checklist. Economic outcomes were presented as ROI. ROI was calculated as ROI = (benefits - costs of program)/costs of program. Results were weighted by study size and combined using meta-analysis techniques. Sensitivity analysis was performed using two additional methodological quality checklists. The influences of quality score and important study characteristics on ROI were explored. Fifty-one studies (61 intervention arms) published between 1984 and 2012 included 261,901 participants and 122,242 controls from nine industry types across 12 countries. Methodological quality scores were highly correlated between checklists (r = .84-.93). Methodological quality improved over time. Overall weighted ROI [mean ± standard deviation (confidence interval)] was 1.38 ± 1.97 (1.38-1.39), which indicated a 138% return on investment. When accounting for methodological quality, an inverse relationship to ROI was found. High-quality studies (n = 18) had a smaller mean ROI, 0.26 ± 1.74 (.23-.30), compared to moderate (n = 16) 0.90 ± 1.25 (.90-.91) and low-quality (n = 27) 2.32 ± 2.14 (2.30-2.33) studies. Randomized control trials (RCTs) (n = 12) exhibited negative ROI, -0.22 ± 2.41(-.27 to -.16). Financial returns become

  3. The meaning of quality work from the general practitioner's perspective: an interview study

    2006-10-01

    Full Text Available Abstract Background The quality of health care and its costs have been a subject of considerable attention and lively discussion. Various methods have been introduced to measure, assess, and improve the quality of health care. Many professionals in health care have criticized quality work and its methods as being unsuitable for health care. The aim of the study was to obtain a deeper understanding of the meaning of quality work from the general practitioner's perspective. Methods Fourteen general practitioners, seven women and seven men, were interviewed with the aid of a semi-structured interview guide about their experience of quality work. The interviews were tape-recorded and transcribed verbatim. Data collection and analysis were guided by a phenomenological approach intended to capture the essence of the statements. Results Two fundamentally different ways to view quality work emerged from the statements: A pronounced top-down perspective with elements of control, and an intra-profession or bottom-up perspective. From the top-down perspective, quality work was described as something that infringes professional freedom. From the bottom-up perspective the statements described quality work as a self-evident duty and as a professional attitude to the medical vocation, guided by the principles of medical ethics. Follow-up with a bottom-up approach is best done in internal processes, with the profession itself designing structures and methods based on its own needs. Conclusions The study indicates that general practitioners view internal follow-up as a professional obligation but external control as an imposition. This opposition entails a difficulty in achieving systematism in follow-up and quality work in health care. If the statutory standards for systematic quality work are to gain a real foothold, they must be packaged in such a way that general practitioners feel that both perspectives can be reconciled.

    Full Text Available This paper describes internal quality system petformance at three Indonesian nursing schools and examines the match of the existing accreditation programmes with the developing internal quality system. A cross sectional study is used with self-administered questionnaires and applied to selected nursing schools. The questionnaire was designed according tocategories of framework of total quality management model. Interview and discussion with respondents including snowball sampling to other teachers and staffs were petformed to clarify and validate data and to enriched the information The activities measured were the enabling and the results factors. The enablers were including Leaderships, strategy, resources, human resources, educational management, teaching teaming process, research and development and also evaluation mechanism, while the results were covering students and personnel satisfaction and partnership.Results shows that some enabling factors were not included in the accreditation, while several indicators in the sub component of accreditation did not explicitly reflect internal quality system petformance. The school stratum as the outcome result of a quality measure is analogue to customer satisfaction, which would depend on direct influence of internal factors such as quality of schools leadership, strategy and educational management. Since the total accreditation score affects school strata and public recognition, it is necessary to use more objectives and relevant indicators by incorporating the internal and external factors as a measure of school quality petformances. Key words: accreditation, education, quality system evaluation, nursing

    Full Text Available Methods other than physical-chemical and geochemical analyses can be used to assess water quality in surface drainage. This study used intolerant, tolerant and resistant benthic species as bioindicators of changes in water quality of two streams, taking in account particle size of sediments and volatile solids. Eight points were sampled in the stream Bandeirinha and four points in the stream Josefa Gomes in January and September 2013 in the municipality of Formosa-GO. The two streams were chosen in order to study two different environments. The study used the diversity indexes of Shannon (H, Equitability (E and Bray-Curtis Similarity and the grouping analysis method UPGMA (Unweighted Pair Group Method with Arithmetic Mean. The results of particle size and volatile solids study of Bandeirinha stream located in rural areas showed bioindicator species intolerant of changes in water quality. The stream Josefa Gomes, completely inserted in an urban environment, showed alteration identified by tolerant and resistant species. The results demonstrate differences in water quality in the rural and urban environments and the relationship of bioindicators with sediments. The study aids the interpretation of changes in the water quality of the two drainages areas. Analysis of water quality based upon benthic biological indicators associated with physical-chemical and geochemical analyses of water and sediments provide a better interpretation of the results.

    Over a one-year period, measurements of indoor air pollutants (CO/sub x/, NO/sub x/, formaldehyde, volatile organics, particulates, and radon) were made in 40 homes in East Tennessee. The houses were of various ages with different types of insulation and heating. Over one-half of the houses exceeded the ASHRAE indoor ceiling guideline of 0.1 ppM for formaldehyde on at least one occasion. Over the duration of the study, older houses averaged 0.04 ppM of formaldehyde while houses less than 5 years old averaged 0.08 ppM (P < 0.01). The highest concentration of formaldehyde measured was 0.4 ppM in a new home. Diurnal and seasonal fluctuations in levels of formaldehyde in some homes were as much as twofold and tenfold, respectively. The highest levels of formaldehyde were usually recorded during summer months. The concentration in indoor air of various organics was at least tenfold higher than in outdoor air. Carbon monoxide and nitrgen oxides were usually <2 and <0.02 ppM, respectively, except when gas stoves or kerosene space heaters were operating, or when a car was running in the garage. In 30% of the houses, the annual indoor guideline for radon, 4 pCi/L, was exceeded. The mean radon level in houses built on the ridgelines was 4.4 pCi/L, while houses located in the valleys had a mean level of 1.7 pCi/L (P < 0.01). The factor having the most impact on infiltration was operation of the central duct fan of the heating, ventilation, and air conditioning system. The mean rate of air exchange increased from 0.39 to 0.74 h/sup -1/ when the duct fan was operated (measurements prior to December 1982). This report presents the study design and implementation, describes the monitoring protocols, and provides a complete set of the data collected during the project. 25 references, 29 figures, 42 tables.

    Heron's Head Park, formerly known as Pier 98, is a 24-acre restored wetland, owned and operated by the Port of San Francisco and situated at the base of the Hunter's Point Power Plant. Heron's Head is a unique environment that is built on landfill and is now a thriving marsh maintained primarily by youth and community volunteers. Adjacent to the park stands a PG&E power plant (closed May 2006), a county waste transfer station, and a combined sewer overflow (CSO) pipe. The park is bordered by San Francisco Bay on the north, east and south sides of the park. We examined the levels of ammonia, nitrite, nitrate, phosphate and fecal coliform at nine sites around the park. Utilizing historical data from other San Francisco Bay sites and other similar estuarine settings in California, we assessed the health of the Bay waters surrounding the park. We found the levels of ammonia, nitrate, nitrite and phosphates to be within the parameters of historical San Francisco Bay data and similar to settings such as Elkhorn Slough, Tomales Bay and Tijuana Estuary. In our study we did find a potential hazard to human health. Fecal coliform concentrations in waters that border the park range from 340 MPN/100 mL - 24,000 MPN/100 mL. This level significantly exceeds Environmental Protection Agency recommendations of 300 MPN/100 mL for human contact with water.

    The Fricke xylenol gel (FXG) dosimeter has been studied for application in radiotherapy because it is capable of to measure the spatial distribution of radiation doses. The dosimetry is based on the oxidation of ferrous (Fe2+) to ferric (Fe3+) ions radiation induced, related to the radiation dose. The gel material usually employed is the 300 Bloom gelatin, which is imported and very expensive in Brazil. Aiming to analyze the viability of to use a locally produced and low cost gel material, in this work the spectrophotometric responses of FXG solutions prepared using 270 Bloom gelatin commercially available and 300 Bloom gelatin imported were compared. The absorption spectra of solutions prepared with 5% by weight 270 and 300 Bloom gelatins non-irradiated and irradiated with 60Co gamma radiation in the dose range between 0.5 and 100 Gy were analysed, the dose-response curves were evaluated and the useful dose range was established. The obtained results indicate that the FXG solution prepared with 270 Bloom gelatin presents good performance, similar to that presented by the FXG solution prepared with 300 Bloom gelatin and its use can be recommended owing to the low cost and the availability in local market.

    Quality of life is a broad concept that presents a challenge to measure as a scientific category. Quality of life encompasses a broad range of variables based on an individual's expression of life satisfaction, perceptions, values, feelings of subjective well-being, and happiness. This study identified and examined factors that influenced the quality of life of Ohio farmers with disabilities who were enrolled in the Ohio AgrAbility Program (OAP) (n = 55) and participated in this study (60% response rate). A 34-item questionnaire was created. The sample of OAP farmers reported stress many days a week, had a negative outlook on life, and were less satisfied with their overall quality of life because of their health. The OAP participants reported external factors, such as cost of equipment, financial pressures, and input costs, as having a negative effect on their quality of life. The participants also reported that they were not satisfied with the amount of vacation time (60.6%), managing farm work and family life (54.6%), overall health (55%), and quality of life (27%). The results showed a significant difference between the OAP participants' overall quality of life and the following variables: gender, net cash income, outlook on life, health, stress, farm work, managing farm and family, social activities, and emotional support for farmers with disabilities. The findings of this exploratory study allowed farmers to identify factors that they perceived as important to their quality of life. Moreover, the results may be helpful for stakeholders to better understand the needs of farmers with disabilities and provide appropriate educational and other services to enhance their quality of life.

    The external evaluation of quality of clinical laboratory examinations was gradually introduced in USSR medical laboratories since 1970s. In Russia, in the middle of 1990 a unified all-national system of external evaluation quality was organized known as the Federal center of external evaluation of quality at the basis of laboratory of the state research center of preventive medicine. The main positions of policy in this area were neatly formulated in the guidance documents of ministry of Health. Nowadays, the center of external evaluation of quality proposes 100 and more types of control studies and permanently extends their specter starting from interests of different disciplines of clinical medicine. The consistent participation of laboratories in the cycles of external evaluation of quality intrinsically promotes improvement of indicators of properness and precision of analysis results and increases reliability of laboratory information. However, a significant percentage of laboratories does not participate at all in external evaluation of quality or takes part in control process irregularly and in limited number of tests. The managers of a number of medical organizations disregard the application of the proposed possibilities to increase reliability of laboratory information and limit financing of studies in the field of quality control. The article proposes to adopt the national standard on the basis of ISO 17043 "Evaluation of compliance. The common requirements of professional competence testing".

    There are four ecologically important river catchments that contain candidate Special Areas of Conservation (cSACs) under the Habitats Directive in the Lake District National Park located in the North of England. These are the rivers Ehen, Kent, Derwent and Eden. For each cSAC, there are defined ecological criteria that include water quality targets to protect the designated species. Stretches of the riverine cSACs in each catchment are failing to meet these and other water quality targets. The Environment Agency commissioned a study of each catchment to provide the underpinning scientific knowledge to allow it to deliver its statutory obligations under the Habitats Directive. SIMCAT river water quality models were produced and used to predict the water quality impacts resulting from a number of water quality planning scenarios aimed at achieving full compliance with the Habitats Directive and other national and EEC water quality targets. The results indicated that further controls on effluent discharges will allow the majority of targets to be met but other sources of pollution will also need to be controlled. The outcome of the study also recognised that water quality improvements alone will not necessarily produce the required improvement to the ecological interest features in each cSAC.

    The aim of this study was to evaluate the effectiveness of improving sleep quality interventions in menopausal women with sleep disturbance. Sleep disturbances are an extensive and common problem among menopausal women. There is an increased trend in the use of non-pharmacological methods to alleviate sleep disturbances. Studies that have implemented two or more non-pharmacological strategies for menopausal women are scant. A repeat measurement with a randomized assignment was conducted. A total of 59 menopausal women with sleep disturbance were recruited and randomly assigned to experimental (n = 29) and control (n = 30) groups. Participants in the experimental group received four 2-hour improving sleep quality activities, whereas the control group received regular greeting calls. Sleep quality was measured prior to intervention, and on the 5th and 8th weeks by using the Pittsburg's Sleep Quality Index, and Actiwatch was worn before and during the 8 weeks of intervention. Generalized estimating equation was used to analyze data. The results revealed that subjective sleep quality had significant main effect in group and time. The findings of the objective measurement showed that participants in the experimental group had significantly shorter frequency of awakening time and increased sleep efficiency. The improving sleep quality intervention is a healthy and cost-effective method to improve sleep quality in community-dwelling menopausal women with sleep disturbance. Copyright © 2015 Elsevier Inc.

    The main aim of this review study was to identify which factors that characterise the relationship between work culture and quality of care in nursing homes. This review study was structured through systematic search methods to identify articles that describe the relationship between work culture and quality of care in nursing homes. The database search yielded 14510 hits. Closer examination showed that 10401 of these hits were duplicates. Of the remaining 4109 articles, only 10 were related to our aim for the study. A qualitative method were used to explain and understand phenomena of work culture and quality if care in nursing homes. Nine out of 10 articles in this review study emphasise the importance of leadership style and supportive management to increase quality of care in nursing homes. Increased empowerment, participation and influence were important factors for improving quality of care. Significant associations between work culture and quality of care and between empowerment and quality of care were reported. Nursing management and leaders must take in consideration that work culture is crucial for improving quality of care in nursing homes, and this study can be used to increase the focus on the work culture among healthcare personnel in nursing homes. Changes are necessary to increase healthcare personnel's job satisfaction, empowerment, autonomy and influence in nursing homes. Giving empowerment to the healthcare personnel working in nursing homes is both an organisational and an interpersonal issue. Being given empowerment and influence over their own work situation, the healthcare workers can be more committed and involved in the goal of obtaining best possible care to the residents. © 2013 Nordic College of Caring Science.

    The modern psychiatric view of schizophrenia spectrum disorders and their treatment has led to an increasing focus on coping strategies and the quality of life of these patients. In the present study, the authors examined the relationship between demographic data, the severity of symptoms, coping strategies, and the quality of life in psychotic patients. It is important to study the inner experience and striving of these individuals as it has been linked to their well-being and treatment adherence. Psychiatric outpatients who met International Classification of Diseases, Tenth Revision criteria for a psychotic disorder (schizophrenia, schizoaffective disorder, or delusional disorder) were recruited in the study. Questionnaires measuring the coping strategies (The Stress Coping Style Questionnaire [SVF-78]), the quality of life (Quality of Life Satisfaction and Enjoyment Questionnaire [Q-LES-Q]), and symptom severity (objective and subjective Clinical Global Impression - objCGI; subjCGI) were assessed. The data were analyzed using one-way analysis of variance, Mann-Whitney U test, Pearson and Spearman correlation coefficients, and multiple regression analysis. A total of 109 psychotic patients were included in the study. The quality of life was significantly related to both the positive and negative coping strategies. The severity of disorder was highly negatively correlated with the quality of life score. The results of multiple stepwise regression analysis using the quality of life as a dependent variable showed that symptom severity (subjCGI, difference between subjCGI, and objCGI), negative coping strategies, positive coping strategies, and the difference between positive and negative coping strategies explain more than half variance. Our study suggests the importance of utilizing the positive coping strategies in improving the quality of life in patients with psychotic disorders.

    According to institutional theorists, the forms and business models of corporation are mainly shaped by factors such as politics, regulations, social norms and cultures. This paper examines how the International Financial Reporting Standards (IFRS) and institutional environment influence the accounting quality, in response to the threat of political extraction in China. We took mainland China as an example instead in our study, following the accounting quality definition of Barth et al. [2], we found that the developments of Chinese government performance audit are conspicuously different by region; to reflect such differences, we elaborated our research by dividing mainland China into 31 categories (provinces or cities). We set 2003-2010 as the time horizon for this study. After testing the Regression model, our empirical research achieved two conclusions: 1) IFRS adoption in China should significantly improve the accounting quality, and 2) IFRS and institutional environment should synthetically influence the quality of accounting as well.

    Urban air pollution is a major environmental problem in several developing countries in the world. This phenomenon seems to be related to the growth of both the urban population in large cities and the number of old and poorly maintained car fleets. The expected rise of population in the next century in countries which suffer from lack of capital for air pollution control, means that there is a great potential for the worsening of the air quality. The worldwide promote policy to phase out lead in gasolines has not proved to be an adequate option in improving the environmental quality. Mexico City Metropolitan Area (MCMA) represents a case in which the introduction of reformulated gasolines in an old car fleet has resulted in the reduction of the airborne lead levels but has worsened the ozone concentration of its urban atmosphere. This paper critically analyzes the chronological evolution of the ozone air pollution problem in MCMA after the successive occurrence of several changes in the formulation of low leaded and unleaded gasolines. It also presents evidences of the usefulness potential of air quality monitoring activities and air quality impact studies on the definition of realistic fuel reformulation policies of developing countries.

    Full Text Available Introduction. Effective treatments for osteoarthritis are available, yet little is known about the quality of primary care in the Republic of Srpska for this disabling condition. Objective. The main objective of this study was to analyze the overall quality of osteoarthritis treatment in a family medicine setting, as well as to explore whether the achievement of quality indicators was associated with particular patient characteristics and severity of osteoarthritis. Methods. The cross-sectional study included 120 patients with confirmed hand, knee, and hip osteoarthritis, recruited at seven family practices in the town of Ugljevik, Republic of Srpska, Bosnia and Herzegovina. Data were extracted from a patient questionnaire on quality indicators, as well as from their electronic and paper records, to assess care against 14 indicators. The included quality indicators were based on the Arthritis Foundation’s Quality Indicator set for Osteoarthritis. Summary achievement rates for hip, knee, or hand osteoarthritis, as well as for the total sample, were calculated. Results. The mean achievement rate for all 14 quality indicators obtained from medical records was 74%, and 77% obtained from patient interview. The quality indicators concerning referral for weight reduction (23% and pharmacological treatment (24% had the lowest achievement rates, whereas the highest achievement rates were related to physical examination (100%, pain and functional assessment (100%, and education (90.8%. Patients physical functioning was significantly associated with the quality indicator achievement rate (p = 0.001. Conclusion. Pharmacological therapy and the referral of osteoarthritis patients in need of weight reduction seem to have the greatest potential for improvement in primary health care.

    We evaluated the methodological quality of economic evaluation studies in the field of obstetrics and gynecology published in the last decade. A MEDLINE search was performed to find economic evaluation studies in obstetrics and gynecology from the years 1997 through 2009. We included full economic evaluation studies concerning tests or interventions in the field of obstetrics or gynecology. Each included study was evaluated by two reviewers using a quality checklist that was based on international guidelines for medical economic evaluation studies and a checklist used in a previous review. The mean number of quality criteria adhered to was 23 of 30 items, whereas five articles (3%) met all 30 criteria. Compliance was low for the description of the perspective (40%), the completeness of costs looking at the perspective (48%) or time horizon (48%), and reporting of quantities of resources (47%). Furthermore, if no discounting was applied, an explanation was infrequently given (14%). A comparison of study quality to that reported by Smith and Blackmore showed a considerable improvement in the following criteria: presentation perspective (from 19 to 40%), statement of primary outcome measure (from 72 to 81%), completeness costs looking at the time horizon (from 14 to 48%), the presentation of discount rates (from 10 to 54%), details of sensitivity analyses (from 21 to 61%), reporting incremental results (from 17 to 70%), and reporting a summary measure (from 57 to 74%). The quality of economic studies in obstetrics and gynecology has considerably improved in the last decade, but room for further improvement is present.

    Health promotion has been defined by the World Health Organization's (WHO) 2005 Bangkok Charter for Health Promotion as "the process of enabling people to increase control over their health and its determinants, and thereby improve their health". One of the most important determinants of health is quality of life. Hand eczema is a common skin disease that can adversely affect the quality of life of patients. The aim of this study was to determine the quality of life in patients with hand eczema. This case-control study was performed on 70 patients with hand eczema and 70 healthy controls. All the patients filled out two questionnaires: Short Form 36 (SF-36) and Dermatology Life Quality index (DLQI). The data were analyzed using the statistical software package for social sciences (SPSS). The mean score score of quality of life in dimensions of physical functioning, vitality, and general health in the SF-36 was lower compared to the control group. The mean score in DLQI in patients with hand eczema was 8.68. There was a significant negative correlation between the scores of different dimensions of QOL obtained in the two questionnaires (SF36 and DLQI). The study demonstrated that the quality of life in patients with hand eczema was lower than that of controls. It seems advisable that psychiatric consultations or psychotherapy be included in the treatment of chronic hand eczema.

    Full Text Available The wide usage of IT enabled options for service delivery has increased the occurrence of irrepressible service failures in the contemporary banking landscape. The enhanced service quality levels exhibited by the dedicated employees suffer badly due to ever-increasing number of tech-driven service failures. The purpose of this study was to examine the linkages among constructs such as perceived service quality, perceived organizational service orientation, perceived automation quality, perceived employee proficiency and perceived service recovery quality to recovery satisfaction in the E-banking context. This investigation examined the moderating role of perceived initial negative feelings of the customer due to service failures, on recovery satisfaction. Data collected from 248 banking customers were analyzed by structural equation modeling approach using, Smart PLS 2.0 M 3, software to identify significant linkages among variables under study. Apart from perceived employee proficiency, all other variables significantly developed perceived service recovery quality leading to recovery satisfaction. Initial negative feelings from a service failure failed to cause significant moderating effect on post recovery satisfaction. The most disturbing service failures in the automated service delivery environment was identified as technical failures such as delay in online transactions, issues related to ATMs and interrupted connectivity. The study could establish that excellent service recovery quality develops service recovery satisfaction and customers gain more confidence in the bank and perceive higher value in their association with the bank.

    Ciliwung is the biggest river in Jakarta. It is 119 km long with a catchment area of 476 km2. It flows from Bogor Regency and crosses Bogor City, Depok City, and Jakarta before finally flowing into Java Sea through Jakarta Bay. The water quality in Ciliwung River has degraded. Many factors affect water quality. Understanding the relationship between land use and surface water quality is necessary for effective water management. It has been widely accepted that there is a close relationship between the land use type and water quality. This study aims to analyze the influence of various land use types on the water quality within the Ciliwung Watershed based on the water quality monitoring data and remote sensing data in 2010 and 2014. Water quality parameters exhibited significant variations between the urban-dominated and forest-dominated sites. The proportion of urban land was strongly positively associated with total nitrogen and ammonia nitrogen concentrations. The result can provide scientific reference for the local land use optimization and water pollution control and guidance for the formulation of policies to coordinate the exploitation and protection of the water resource.

In order to investigate mental health and the quality of life of addicts referring to addiction centers in Golestan province, this research was done. Methods: A total of 322 patients were selected from the addiction census centers of the province during 2009 and studied in a descriptive cross-sectional analysis. The data included a questionnaire about demographic characteristics and two questionnaires contained the mental health (MHC and the quality of life (SF17 variables. Results: Of the total, 52 percent reported their mental health to be somewhat favorable and 17 percent reported favorable. On the other hand, 53 percent reported somewhat favorable quality of life and 8 percent had a desirable quality of life. There was significant relationship between mental health and quality of life. Mental health was significantly related to sex and type of material consumption, while quality of life was significantly related to job and type of material consumed. Conclusion: Many addicts can’t give up addiction and repeatedly refer to centers. But care team members can identify common characteristics, personality traits and support systems for promoting mental health and the quality of addict’s life which facilitate prevention, treatment and rehabilitation.

    Quality in health care can be seen as having three principal dimensions: service, technical and customer quality. This study aimed to measure Customer Quality in relation to self-management of Type 2 diabetes. A cross-sectional survey of 577 Type 2 diabetes people was carried out in Australia. The 13-item Patient Activation Measure was used to evaluate Customer Quality based on self-reported knowledge, skills and confidence in four stages of self-management. All statistical analyses were conducted using SPSS 13.0. All participants achieved scores at the level of stage 1, but ten percent did not achieve score levels consistent with stage 2 and a further 16% did not reach the actual action stage. Seventy-four percent reported capacity for taking action for self-management and 38% reported the highest Customer Quality score and ability to change the action by changing health and environment. Participants with a higher education attainment, better diabetes control status and those who maintain continuity of care reported a higher Customer Quality score, reflecting higher capacity for self-management. Specific capacity building programs for health care providers and people with Type 2 diabetes are needed to increase their knowledge and skills; and improve their confidence to self-management, to achieve improved quality of delivered care and better health outcomes.

    Full Text Available The aim of the following study is to analyze the quality of operations in local transport companies, which includes operations according to certain international, European and national standards and regulations. Special emphasis is placed on the research in the field of standards, quality system and the implementation of the ISO series of standards 9000 for road companies. The implementation of a Quality Management System (QMS is essential for companies seeking competition on the international market. This paper presents the results of the research which was carried out in Serbia at the end of 2012 on the sample of enterprises by interviewing managers on quality culture as well as departments dealing with the quality system of the company. Interviewees are from the following companies: those that have introduced the ISO standards or other quality management system, companies that conduct consultations to introduce the system, etc. Although respondents ranked the quality management function as the second most important of them all, after the function of telecommunications companies, the research revealed that managers within transport companies in Serbia are insufficiently aware of the importance of introducing QMS for achieving better business operations. The research results within other services of surveyed companies show that this constitutes an unnecessary expense (for each company, and that the position of managers within these services is redundant. Thereinafter, the companies were ranked by their activities in the field of transportation, the number of employees and the type of organization.

    New determinants of quality of life in schizophrenia need to be identified. As sensory gating deficit is core impairment in schizophrenia, the present study hypothesized that sensory gating deficit is a determinant of impaired quality of life in schizophrenia. This study therefore investigated the relationship between sensory gating deficit and quality of life in patients with schizophrenia after adjusting for key confounding factors. Sensory gating was assessed with the auditory event-related potential method by measuring P50 amplitude changes in a double-click conditioning-testing procedure, perceptual impairments related to sensory gating deficit was assessed with the SGI questionnaire and quality of life was assessed with the SQoL 18 questionnaire in 39 patients with schizophrenia. Patients with sensory gating deficit (n=14) had a lower subjective quality of life on the psychological well-being dimension evaluated with SQoL 18 questionnaire (p=0.008) compared to those without it (n=25). This result remained significant (B=-0.45, Wald=4.84, p=0.02) after taking into account 7 potential confounding factors (gender, age, level of education, duration of disorder, positive symptoms, depressive symptoms and anxiety symptoms). Poorer psychological well-being was related to a higher score on the SGI (rho=-0.40, p=0.01), in particular on the Distractibility dimension (rho=-0.47, p=0.001). These findings suggest that sensory gating deficit may be a determinant of impaired quality of life in schizophrenia. Further studies are needed to address the causal relationship between sensory gating deficit, perceptual impairments, attentional deficit and impaired quality of life in schizophrenia in order to act more efficiently on the quality of life of patients with this disorder.

    Studying public perception on drinking water quality is crucial for managing of water resources, generation of water quality standards, and surveillance of the drinking-water quality. However, in policy discourse, the reliability of public perception concerning drinking water quality and associated health risks is questionable. Does the public perception of water quality equate with the actual water quality? We investigated public perceptions of water quality and the perceived health risks and associated with the actual quality of public water supplies in the same communities. The study was conducted in 45 communities of Newfoundland (Canada) in 2012. First, a telephone survey of 100 households was conducted to examine public perceptions of drinking water quality of their respective public sources. Then we extracted public water quality reports of the same communities (1988-2011) from the provincial government's water resources portal. These reports contained the analysis of 2091 water samples, including levels of Disinfection By-Products (DBPs), nutrients, metals, ions and physical parameters. The reports showed that colour, manganese, total dissolved solids, iron, turbidity, and DBPs were the major detected parameters in the public water. However, the majority of the respondents (>56%) were either completely satisfied or very satisfied with the quality of drinking water. Older, higher educated and high-income group respondents were more satisfied with water quality than the younger, less educated and low-income group respondents. The study showed that there was no association with public satisfaction level and actual water quality of the respective communities. Even, in the communities, supplied by the same water system, the respondents had differences in opinion. Despite the effort by the provincial government to make the water-test results available on its website for years, the study showed existing disconnectedness between public perception of drinking water

    Objective To describe patients’ perceived value and use of quality measures in evaluating and choosing community pharmacies. Design Focus group methodology was combined with a survey tool. During the focus groups, participants assessed the value of the Pharmacy Quality Alliance's quality measures in evaluating and choosing a pharmacy. Also, participants completed questionnaires rating their perceived value of quality measures in evaluating a pharmacy (1 being low value and 5 being high) or choosing a pharmacy (yes/no). Thematic analysis and descriptive statistics were used to analyse the focus groups and surveys, respectively. Setting Semistructured focus groups were conducted in a private meeting space of an urban and a rural area of a Mid-western State in the USA. Participants Thirty-four adults who filled prescription medications in community pharmacies for a chronic illness were recruited in community pharmacies, senior centres and public libraries. Results While comments indicated that all measures were important, medication safety measures (eg, drug-drug interactions) were valued more highly than others. Rating of quality measure utility in evaluating a pharmacy ranged from a mean of 4.88 (‘drug-drug interactions’) to a mean of 4.0 (‘absence of controller therapy for patients with asthma’). Patients were hesitant to use quality information in choosing a pharmacy (depending on the participant's location) but might consider if moving to a new area or having had a negative pharmacy experience. Use of select quality measures to choose a pharmacy ranged from 97.1% of participants using ‘drug-drug interactions’ (medication safety measure) to 55.9% using ‘absence of controller therapy for patients with asthma’. Conclusions The study participants valued quality measures in evaluating and selecting a community pharmacy, with medication safety measures valued highest. The participants reported that the quality measures would not typically cause a

    Assessments of methodological and reporting quality are critical to adequately judging the credibility of a study's conclusions and to gauging its potential reproducibility. To aid those seeking to assess the methodological or reporting quality of studies relevant to toxicology, we conducted a scoping review of the available guidance with respect to four types of studies: in vivo and in vitro, (quantitative) structure-activity relationships ([Q]SARs), physico-chemical, and human observational studies. Our aims were to identify the available guidance in this diverse literature, briefly summarize each document, and distill the common elements of these documents for each study type. In general, we found considerable guidance for in vivo and human studies, but only one paper addressed in vitro studies exclusively. The guidance for (Q)SAR studies and physico-chemical studies was scant but authoritative. There was substantial overlap across guidance documents in the proposed criteria for both methodological and reporting quality. Some guidance documents address toxicology research directly, whereas others address preclinical research generally or clinical research and therefore may not be fully applicable to the toxicology context without some translation. Another challenge is the degree to which assessments of methodological quality in toxicology should focus on risk of bias - as in clinical medicine and healthcare - or be broadened to include other quality measures, such as confirming the identity of test substances prior to exposure. Our review is intended primarily for those in toxicology and risk assessment seeking an entry point into the extensive and diverse literature on methodological and reporting quality applicable to their work.

    Purpose Research on accreditation has mostly focused on assessing its impact using large scale quantitative studies, yet little is known on how quality is improved in practice through an accreditation process. Using a case study of an acute teaching hospital in Portugal, the purpose of this paper is to explore the dynamics through which accreditation can lead to an improvement in the quality of healthcare services provided. Design/methodology/approach Data for the case study was collected through 46 in-depth semi-structured interviews with 49 clinical and non-clinical members of staff. Data were analyzed using a framework thematic analysis. Findings Interviewees felt that hospital accreditation contributed to the improvement of healthcare quality in general, and more specifically to patient safety, as it fostered staff reflection, a higher standardization of practices, and a greater focus on quality improvement. However, findings also suggest that the positive impact of accreditation resulted from the approach the hospital adopted in its implementation as well as the fact that several of the procedures and practices required by accreditation were already in place at the hospital, albeit often in an informal way. Research limitations/implications The study was conducted in only one hospital. The design of an accreditation implementation plan tailored to the hospital's context can significantly contribute to positive outcomes in terms of quality and patient safety improvements. Originality/value This study provides a better understanding of how accreditation can contribute to healthcare quality improvement. It offers important lessons on the factors and processes that potentiate quality improvements through accreditation.

    Since 1996, the U.S. Geological Survey (USGS), in cooperation with the City of Wichita, has done studies in the Cheney Reservoir watershed to understand environmental effects on water-quality conditions. Early studies (1996–2001) determined subwatershed sources of contaminants, nutrient and sediment loading to Cheney Reservoir, changes in reservoir sediment quality over time, and watershed sources of phosphorus. Later studies (2001–present) focused on nutrient and sediment concentrations and mass transport from the watershed; the presence of cyanobacteria, cyanotoxins, and taste-and-odor compounds in the reservoir; and development of regression models for real-time computations of water-quality constituents of interest that may affect drinking-water treatment. This fact sheet summarizes key results from studies done by the USGS during 1996–2016 in the Cheney Reservoir watershed and Cheney Reservoir.

    The global increase in elderly population all over the world, especially in Portugal, justifies the importance of mental health study in this age group. The aim of this study was to characterize the elderly patients in Gerontopsychiatry Consultation of Centro Hospitalar São João in Porto, related to socio-demographic aspects, physical and global disabilities, depression, suicidal ideation and quality of life, and to explore the association between suicidal ideation, depression, and quality of life and global and functional disability. In this cross-sectional study, 155 patients were recruited consecutively, with a final sample of 75 subjects (59 women and 16 men) without cognitive deficits and a mean age of 72.8 (SD = 6.04). Concerning the depression level measured with the Geriatric Depression Scale (Barreto et al., 2008) it was found that 66.7% presented severe depression and suicidal ideation (M = 41.96, SD = 36.38), a value considered with a potential risk of suicide using the Suicidal Ideation Questionnaire (Ferreira & Castela, 1999). The elderly also perceived their quality of life as low, revealing global disability assessed with the EasyCare- Elderly Assessment (Sousa & Figueiredo, 2000a). A significant positive correlation was also found between depression and suicidal ideation (rs =.71, p quality of life (rs = .50, p quality of life (rs = .40, p < .001). The data obtained in this study corroborate the results found in other studies.

    Sleep disorders are very common in patients with chronic obstructive pulmonary disease (COPD). However, it is not clear how sleep disorders and quality of life (QoL) affect each other in the different stages of disease progression. This descriptive-correlational study investigated the relationship between QoL, quality of sleep, and degree of disease progression in 102 outpatients with COPD. The results showed that the QoL in patients with COPD is compromised and worsens with disease progression, and the quality of sleep is significantly associated with QoL and worsened as the disease progressed. The early identification of a risk of alteration of the quality of sleep, especially in nursing care, could facilitate a preventive approach for COPD patients that could positively affect their QoL. © The Author(s) 2015.

    Air quality modeling is one of the tools used in Environmental Impact Assessment (EIA) studies in order to predict the potential impacts of atmospheric emissions. The main advantage of air quality modeling is the simulation of the ground-level concentrations under different conditions (i.e., meteorological variations and other pollutant sources in the vicinity). The accuracy of model predictions, on the other hand, depends mainly on the quality of the input data reflecting meteorological and topographical conditions as well as emission sources. In this regard, the model predictions should be supported with monitoring data. In the paper, the predictions of Gaussian air dispersion model (Industrial Source Complex - ISC) for SO{sub 2} and NO{sub 2} carried out in the vicinity of the Sugozu Power Plant on the coast of Turkey are compared with the air quality monitoring results of the same region. 2 refs., 3 figs., 2 tabs.

    Experimental errors in the genotyping phases of a Genome-Wide Association Study (GWAS) can lead to false positive findings and to spurious associations. An appropriate quality control phase could minimize the effects of this kind of errors. Several filtering criteria can be used to perform quality control. Currently, no formal methods have been proposed for taking into account at the same time these criteria and the experimenter's preferences. In this paper we propose two strategies for setting appropriate genotyping rate thresholds for GWAS quality control. These two approaches are based on the Multi-Criteria Decision Making theory. We have applied our method on a real dataset composed by 734 individuals affected by Arterial Hypertension (AH) and 486 nonagenarians without history of AH. The proposed strategies appear to deal with GWAS quality control in a sound way, as they lead to rationalize and make explicit the experimenter's choices thus providing more reproducible results.

    To evaluate the quality of life and surgical outcomes in women who had undergone colpocleisis. This was a prospective small cohort study conducted between August 2010 and September 2011. Twelve women with pelvic organ prolapse were offered obliterative vaginal surgery and were informed about the surgical procedure. Ten women accepted this operation and were included in the study. Before and after colpocleisis, cases were evaluated by urogynecological examination, and quality of life was assessed by the Turkish language validated prolapse quality of life questionnaire (P-QOL), in which a low total score indicates a good quality of life. The mean age was 74.9±4.5 (range 68-85). The general score of the P-QOL was reduced during the follow-up period, reflecting a significant effect on quality of life and clinical improvement in women with the colpocleisis operation. There was no morbidity due to colpocleisis or recurrent pelvic organ prolapse in follow-up period. In our small cohort including elderly women, colpocleisis provided high levels of surgical outcomes as well as a significant improvement in quality of life without significant morbidity.

    Chronic leg ulcers are a public health problem that can have a significant impact on the patient's physical, socioeconomic and psychological status. The aim of this study is to evaluate the quality of life, anxiety and depression, self-esteem and loneliness in patients suffering from leg ulcers. A total of 102 patients were enrolled in the study. The quality of life, anxiety and depression, self-esteem and loneliness of the patient were assessed using the Dermatology Life Quality Index (DLQI), Hospital Anxiety and Depression Scale (HADS), Rosenberg's Self-esteem Scale (RSES) and the UCLA Loneliness Scale (UCLA-Version 3), respectively. The mean DLQI score was 13·38 ± 2·59, suggesting a serious effect on the quality of life of patients. Those with leg ulcers had statistically significant higher scores according to the HADS-total scale (P = 0·031) and HADS-anxiety subscale (P = 0·015) compared with healthy volunteers. Moreover, a statistically significant difference was found between the two groups concerning the UCLA-scale (P = 0·029). Female patients presented with a higher score of anxiety (P = 0·027) and social isolation (P = 0·048), and worse quality of life (P = 0·018) than male patients. A severe quality of life impairment was documented, reflecting a significant psychosocial impact on patients with leg ulcers. © 2014 The Authors.

    Full Text Available INTRODUCTION: The application of health economic evaluation (HEE evidence can play an important role in strategic planning and policy making. This study aimed to assess the scope and quality of existing research, with the goal of elucidating implications for improving the use of HEE evidence in Vietnam. METHODS: A comprehensive search strategy was developed to search medical online databases (Medline, Google Scholar, and Vietnam Medical Databases to select all types of HEE studies except cost-only analyses. Two researchers assessed the quality of selected studies using the Quality of Health Economic Studies (QHES instrument. RESULTS: We selected 26 studies, including 6 published in Vietnam. The majority of these studies focused on infectious diseases (14 studies, with HIV being the most common topic (5 studies. Most papers were cost-effectiveness studies that measured health outcomes using DALY units. Using QHES, we found that the overall quality of HEE studies published internationally was much higher (mean score 88.7+13.3 than that of those published in Vietnam (mean score 67.3+22.9. Lack of costing perspectives, reliable data sources and sensitivity analysis were the main shortcomings of the reviewed studies. CONCLUSION: This review indicates that HEE studies published in Vietnam are limited in scope and number, as well as by several important technical errors or omissions. It is necessary to formalize the process of health economic research in Vietnam and to institutionalize the links between researchers and policy-makers. Additionally, the quality of HEE should be enhanced through education about research techniques, and the implementation of standard HEE guidelines.

    The precise cause of lichen planus is unknown, but the disease seems to be immunologically mediated. It is a psychocutaneous disorder. Due to scarcity of Indian studies in this field, we decided to study in patients of lichen planus the prevalence of depression and quality of life with comparison of the same in both the genders. Patients diagnosed as having lichen planus by consultant dermatologist were enrolled after informed consent and ethics approval. 45 patients were screened, of which 35 who satisfied the criteria were taken up for the study. A semistructured proforma was designed to collect the necessary information with administration of dermatology life quality index and Beck's depression inventory. While 25% were depressed with females being more affected than males, quality of life was impaired in more than 90% patients. Impairment was maximum due to symptoms and illness feelings, disturbed daily activities, or work and time consumption in treatment. There was a strong association between depression and impairment in quality of life in both the genders. This study helps in early identification of psychological problems in lichen planus patients and in planning their future course of management, hence reducing the lack of productivity and improving the prognosis and quality of life.

    The aims of this review were, first to rate the methodological quality of studies which investigate the reliability of manual tests for cervical spine dysfunctions by applying a new quality assessment tool; secondly to compare the outcomes of these studies. The literature search included databases of CINAHL, MEDLINE, AMED, AMI, and SPORT DISCUS, the Cochrane Library, the Physiotherapy Evidence Database (PEDro), the National Library of Medicine (PubMed), Factiva, the EBSCOT HOST Research Database, online journal databases of ELSEVIER Science periodicals, LIPPINCOTT WILLIAMS & WILKINS, ELSEVIER Science @ Direct, THIEME ONLINE, and BLACKWELL SYNERGY. The application of the Quality Assessment of Diagnostic Accuracy Studies tool (QUADAS) to the 15 studies which met the inclusion criteria showed methodological weaknesses such as not considering an independent reference standard, or a representative study population. The studies demonstrated methodological strength in describing selection criteria and in interpreting results. The studies' outcomes make the claim to be able to detect segmental cervical dysfunction based on a manual assessment only questionable. Further improvements in quality, uniform study designs, and a valid reference standard would be necessary in order to obtain more reliable data in the future.

    Johansen, Jeppe; Nielsen, Rikke; Fink-Jensen, Vibeke;

    The number of multi-detector CT examinations is increasing rapidly. They allow high quality reformatted images providing accurate and precise diagnosis at maximum speed. Brain examinations are the most commonly requested studies, and although they come at a lower effective dose than body CT, can...... account to a considerable radiation dose as many patients undergo repeated studies. Therefore, various dose-reduction strategies are applied such as automated tube current and voltage modulation and recently different iterative reconstruction algorithms. However, the trade-off of all dose......-reduction maneuvers is reduction of image quality due to image noise or artifacts. The aim of our study was therefore to find the best diagnostic images with lowest possible dose. We present results of dose- and image quality optimizing strategies of brain CT examinations at our institution. We compare sequential...

    Recent studies suggest that the online and offline behaviors young people display in romantic relationships are closely related. However, the differential effects of the dimensions of couple quality in the online context have not yet been explored in depth. The aim of this study was to explore online couple quality in young-adult relationships, and its association with romantic relationship satisfaction, also looking at effects of gender, age, and length of the relationship. 431 university students currently in a romantic relationship (68.2% females; mean age = 21.57) participated in this study. They completed different self-report measures to tap the online quality of their romantic relationships (online intimacy, control, jealousy, intrusiveness, cyberdating practices, and communication strategies) and level of satisfaction with those relationships. Results showed that participants more often reported online intimacy (M men = 2.49; M women = 2.38) than the negative scales of online quality (mean ranged from .43 to 1.50), and all the online quality scales decreased with age (correlations ranged from -.12 to -.30) and relationship length (correlations ranged from -.02 to -.20). Linear regression analyses indicated that online intimacy (b = .32, p = .001) and intrusiveness (b = .11, p = .035) were positively related to relationship satisfaction, while cyberdating practices (b = -.20, p = .001) and communication strategies (b = -.34, p = .001) were negatively correlated with relationship satisfaction. Moreover, gender and relationship length moderated some of these associations. Results indicate that while online quality and relationship satisfaction are related, the impact of different online quality dimensions on relationship satisfaction differs depending on a participant's sex, age, and relationship length.

A Cross-sectional study was conducted to assess the level of implementation of good practices using a questionnaire. Some quality dimensions were also assessed (scale 0 to 10) by a set of 87 quality coordinators of health centres and a random sample of 54 healthcare professionals working in small centres. Seventy quality coordinators and 27 professionals replied (response rates 80% and 50%, respectively. There were no differences in the assessment of quality attributes between both groups. They identified as areas for improvement: use of practice guidelines (7.6/10), scientific and technical skills (7.5/10), and patient satisfaction (7.7/10). Availability and accessibility to clinical reports, informed consent, availability of hydro-alcoholic solution, and to record allergies, were considered of high importance to be implemented, with training and research, improvements in equipment and technology plans, adherence to clinical practice guidelines and the preparation of risk maps, being of less importance. The good practices related to equipment and resources have a higher likelihood to be implemented, meanwhile those related to quality and safety attitudes have more barriers before being implemented. The mutual has a similar behaviour than other healthcare institutions. Copyright © 2015 SECA. Published by Elsevier Espana. All rights reserved.

    A mass spectrometry method has been developed using the Quality by Design (QbD) principle. Direct analysis in real time mass spectrometry (DART-MS) was adopted to analyze a pharmaceutical preparation. A fishbone diagram for DART-MS and the Plackett-Burman design were utilized to evaluate the impact of a number of factors on the method performance. Multivariate regression and Pareto ranking analysis indicated that the temperature, determined distance, and sampler speed were statistically significant (P design combined with response surface analysis was then employed to study the relationships between these three factors and the quality of the DART-MS analysis. The analytical design space of DART-MS was thus constructed and its robustness was validated. In this presented approach, method performance was mathematically described as a composite desirability function of the critical quality attributes (CQAs). Two terms of method validation, including analytical repeatability and method robustness, were carried out at an operating work point. Finally, the validated method was successfully applied to the pharmaceutical quality assurance in different manufacturing batches. These results revealed that the QbD concept was practical in DART-MS method development. Meanwhile, the determined quality was controlled by the analytical design space. This presented strategy provided a tutorial to the development of a robust QbD-compliant mass spectrometry method for industrial quality control.

Cross-sectional study. Internet. Websites on vaccines. Using "vacunas OR vaccines" as key words, the features of 40 web pages were analysed. These web pages were selected from the page results of two search engines, Google and Yahoo! Based on a total of 9 criteria, the average score of criteria fulfilled was 7 (95% CI 3.96-10.04) points for the web pages offered by Yahoo! and 7.3 (95% CI 3.86-10.74) offered by Google. Amongst web pages offered by Yahoo!, there were three with clearly inaccurate information, while there were four in the pages offered by Google. Trust marks were displayed in 20% and 30% medical web pages, respectively, and their presence reached statistical significance (P=0.033) when fulfilling the quality criteria compared with web pages where trust marks were not displayed. A wide variety of web pages was obtained by search engines and a large number of them with useless information. Although the websites analysed had a good quality, between 15% and 20% showed inaccurate information. Websites where trust marks were displayed had more quality than those that did not display one and none of them were included amongst those where inaccurate information was found.

    Hyperhidrosis is an excessive sweating disorder affecting quality of life. Endoscopic thoracic sympathectomy (ETS), introduced by Kux in 1951, is currently the gold standard surgical treatment for primary hyperhidrosis. 75% of patients with primary hyperhidrosis have seen improvement in quality of life within 30 days after surgery. Compensatory hyperhidrosis and pneumothorax (up to 75%) have been reported in patients after surgery. This study evaluates the functional status, self- esteem, compensatory hyperhidrosis and quality of life among patient with primary hyperhidrosis before and after undergoing ETS. Fifty (n=50) patients between the ages 18 to 30, with primary hyperhidrosis were recruited. Patients answered the quality of life questionnaire and Rosenberg self-esteem questionnaire prior to surgery and 30 days post surgery on follow up. Any post-operative complications were documented. Telephone interviews were held for patients who were unable to attend the clinics for follow-up. Forty six patients (92%) had symptomatic relieve within 30 days of surgery. The incidence of compensatory sweating was 78% (39 patients), with 6 patients developing severe hyperhidrosis. Two patients who did not experience symptomatic relieve, developed compensatory hyperhidrosis. Pneumothorax was documented in 8 patients (16%), with 6 patients requiring chest tubes. Significant improvement in quality of life and self-esteem was seen among patients after surgery. ETS has shown to significantly improve the quality of life and self-esteem of patients with primary hyperhidrosis within 30 days of surgery. However, the rate of compensatory hyperhidrosis still remains high (78%) which requires a long term evaluation.

    Assessment and evaluation of the health-related quality of life of industrial workers is an important research focus. This descriptive correlational study identifies the predictors of health-related quality of life using a random sampling of industrial workers (n = 640) from construction factories in Amman Governorate in Jordan using demographic characteristics, a health and work-related factors questionnaire, and the World Health Organization Quality of Life-Brief scale. Results showed that industrial workers had good physical health but a poor working environment. There was a statistically significant relationship between educational level, conflict between work and individual life and work and social life, working hours, and workload, and all domains of health-related quality of life. Overall, educational level was the main predictor for all domains of health-related quality of life. Such results confirm the need to develop appropriate interventions and strategies to improve workers' health-related quality of life. Furthermore, developing an integrated approach among policymakers, employers, and work organizations to enhance industrial workers' occupational health programs could be effective. © 2017 John Wiley & Sons Australia, Ltd.

    Full Text Available Erudite groups of people, scientists, planners, and policy-makers of different countries have come to realise that quality of environment is not necessarily a simple function of nature as in primitive earth. Today nature’s self-regulatory functions are inoperative. All the developed and developing countries are deeply concerned to make balance between their environmental anxiety and their economic development. Dreadful environmental conditions are affecting the biological segment of the ecosystem of these areas. Human being, ‘one of the most precious component in biosphere’, have regular predicament situation with accretion of sullied air, water, and soil degradation. Though water and land pollution is extremely dangerous, air pollution has its own peculiarities, due to its trans-boundary dispersion of pollutants over the entire world. The effect of air pollution on health is very complex as there are many different sources and their individual effect varying from one to other. It is not only the ambient air quality in the cities but also the indoor air quality in the rural and urban areas that are causing concern. The study is confined with the health impact of deteriorating air quality in Lucknow city. The aim of the present study is also to determine the consequences of ambient air quality on health of the people in the study area.

    International students form a significant proportion of students studying within universities in Western countries. The quality of life perceptions of international medical students in comparison with domestic medical students has not been well documented. There is some evidence to suggest that international medical students may have different educational and social experiences in relation to their domestic peers. This study investigates the levels of quality of life experienced by international and domestic students studying medicine. A total of 548 medical students completed the abbreviated version of the World Health Organization Quality of Life questionnaire. The focus of the analysis was to evaluate differences between international and domestic students in their early clinical years. The responses were analysed using multivariate analysis of variance methods. International medical students are experiencing lower social and environmental quality of life compared with domestic peers. International medical students in New Zealand have expressed quality of life concerns, which likely have an impact on their academic achievement, feelings of wellness, acculturation, and social adaptation. The findings reinforce the need for creating stronger social networks and accessible accommodation, as well as developing systems to ensure safety, peer mentorship and student support.

    A previous study on electromagnetic forming (EM) hemming technology carried out in TECNALIA showed the real capability of this high speed deformation method to produce quality hemmed parts (Jimbert et al., J. Mater. Process. Technol. 211:916-924, 2011). Continuing with the development of this promising new application for the EM technology, some new experiments were run. The objective of this study is to focus on the critical processing factors that affect the final quality of the electromagnetically hemmed parts. For this purpose, an experimental plan was designed changing different input parameters and output quality parameters measured to quantify the results. The flange height limit was obtained for the studied experimental setup and was established at 10 mm. The bending radius and the gap between the inner and the outer part have to be keep to the minimum to increase final quality. In parallel to the physical experiments, EM hemming simulations were carried out using an EM loose coupling simulation method. An EM hemming process simulation of a circular whole part was carried out using shell elements. Results were compared with cross section simulations of the hemmed union using solid elements in order to analyze the importance of the type of element used for EM hemming simulation. Simulations revealed that solid elements reproduce quality aspects better than shell elements.

    Coping strategies used by Multiple Sclerosis patients play a key role in adjusting to the disease and affect their overall quality of life. This relationship has been investigated in developed countries, but none has been studied in developing ones such as Lebanon. Factors including barriers to health care delivery, economic pressure and political instability influence which coping strategies are used and often increases the use of negative coping mechanisms. The current pilot study explored the association between different coping strategies with quality of life and depression, anxiety, fatigue and social support in 34 Lebanese Multiple Sclerosis patients. Results indicated that Multiple Sclerosis patients using positive coping strategies had significantly higher scores of quality of life (U=46, p=.038) and social support (U=33.5, p=.011), and lower depression (U=44, p=.030) and anxiety levels (U=46.5, p=.038) as compared to those using negative coping strategies. Specifically, escape avoidance coping strategy was associated with poor quality of life scores (r=-.609, pstrategies is needed to develop proper therapeutic interventions which increase quality of life. Future studies are required to confirm these results. Copyright © 2015 Elsevier B.V. All rights reserved.

    Estill Voice Training (EVT) is a widely known programme for developing vocal skills based on partitioning the process of vocal production in order to reach control of specific structures in the vocal mechanism. The present retrospective small-scale exploratory study aims at reporting preliminary data about the efficacy of EVT - in terms of voice quality control on a specific vocal exercise - in contemporary commercial singers with a Certificate of Figure Proficiency (CFP). Thirty-five contemporary commercial singers (professional or semi-professional pop and rock singers) with no vocal complaints were recruited. The experimental group was composed of twenty singers who studied EVT and had a CFP. The control group was composed of fifteen singers who studied in Italian contemporary popular music institutions but were not familiar with EVT. Voice quality control was assessed through acoustic and perceptual analysis on a specific vocal exercise requiring sound pitch, perturbation and spectral energy distribution control. The acoustic analysis showed some significant differences between the two groups of singers both in sound perturbation control and spectral energy distribution control, suggesting a higher voice quality control ability for the experimental group. The perceptual evaluation confirmed a higher ability for the experimental group to produce recognizable voice qualities in this specific task. The reported preliminary results seem to suggest EVT as an effective educational system for developing voice quality control ability in contemporary commercial singers.

    Introduction The concept of patient-centred care (PCC) is changing the way healthcare is understood, accepted and delivered. The Institute of Medicine has defined PCC as 1 of its 6 aims to improve healthcare quality. However, in Canada, there are currently no nationwide standards in place for measuring and evaluating healthcare from a patient-centred approach. In this paper, we outline our scoping review protocol to systematically review published and unpublished literature specific to patient-centred quality indicators that have been implemented and evaluated across various care settings. Methods and analysis Arksey and O'Malley's scoping review methodology framework will guide the conduct of this scoping review. We will search electronic databases (MEDLINE, EMBASE, the Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Social Work Abstracts, Social Services Abstracts), grey literature sources and the reference lists of key studies to identify studies appropriate for inclusion. 2 reviewers will independently screen all abstracts and full-text studies for inclusion. We will include any study which focuses on quality indicators in the context of PCC. All bibliographic data, study characteristics and indicators will be collected and analysed using a tool developed through an iterative process by the research team. Indicators will be classified according to a predefined conceptual framework and categorised and described using qualitative content analysis. Ethics and dissemination The scoping review will synthesise patient-centred quality indicators and their characteristics as described in the literature. This review will be the first step to formally identify what quality indicators have been used to evaluate PCC across the healthcare continuum, and will be used to inform a stakeholder consensus process exploring the development of a generic set of patient-centred quality indicators applicable to multiple care settings.

    Despite the adverse effects that treatment for colorectal cancer can have on patients' quality of life and, in particular, their intimate relationships, very little research has been conducted on the psychosocial adjustment for both patients and their partners/spouses. The aim of this systematic review was to examine dyadic studies of adjustment in couples in which one partner has been diagnosed with colorectal cancer. Pub Med, PsychINFO, MEDLINE, Social Sciences Abstracts (EBSCO), and the Cochrane Library were systematically searched for studies reporting quality of life outcomes for colorectal cancer patients and their partners/spouses. Only studies that included dyads in the sample were eligible for inclusion. The Quality Assessment Tool for Quantitative Studies was used to evaluate each study. A total of 277 studies were identified, of which 9 studies met the inclusion criteria (N = 388 couples). The methodological quality of the studies was high in that they used standardized instruments validated with their samples, conducted dyadic data analyses (when appropriate), and used longitudinal designs. A synthesis of the studies revealed that (1) relationship factors (eg, support, communication, dyadic coping, and relationship satisfaction) affect adjustment to cancer; (2) cancer-related distress impacts each partner's adjustment or the relationship; and (3) gender, role (patient/caregiver), and clinical characteristics (treatment, mental health) can mediate adjustment to cancer. The quality of the relationship can influence patients' and their partners' adjustment to colorectal cancer. Psychosocial interventions that address relationship issues may be beneficial to couples facing the challenges of colorectal cancer. Copyright © 2016 John Wiley & Sons, Ltd.

    Workers in Primary Health Care are often exposed to stressful conditions at work. This study investigated the association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers. This cross-sectional study included all 797 Primary Health Care workers of a medium-sized city, Brazil: doctors, nurses, nursing technicians and nursing assistants, dentists, oral health technicians, and auxiliary oral hygienists, and community health workers. Data were collected by interviews. Quality of life was assessed using the WHOQOL-BREF; general quality of life, as well as the physical, psychological, social and environmental domains were considered, with scores from 0 to 100. Higher scores indicate a better quality of life. Poor quality of life was defined by the lowest quartiles of the WHOQOL score distributions for each of the domains. Adverse psychosocial work conditions were investigated by the Effort-Reward Imbalance model. Associations were verified using multiple logistic regression. Poor quality of life was observed in 117 (15.4%) workers. Workers with imbalanced effort-reward (high effort/low reward) had an increased probability of general poor quality of life (OR = 1.91; 1.07–3.42), and in the physical (OR = 1.62; 1.02–2.66), and environmental (OR = 2.39; 1.37–4.16) domains; those with low effort/low reward demonstrated a greater probability of poor quality of life in the social domain (OR = 1.82; 1.00–3.30). Workers with overcommitment at work had an increased likelihood of poor quality of life in the physical (OR = 1.55, 1.06–2.26) and environmental (OR = 1.69; 1.08–2.65) domains. These associations were independent of individual characteristics, job characteristics, lifestyle, perception of general health, or psychological and biological functions. There is an association between adverse psychosocial work conditions and poor quality of life among Primary Health Care workers.

    Full Text Available One way of classifying water quality is by means of indices, in which a series of parameters analyzed are joined a single value, facilitating the interpretation of extensive lists of variables or indicators, underlying the classification of water quality. The objective of this study was to develop a statistically based index to classify water according to the Irrigation Water Quality Index (IWQI, to evaluate the ionic composition of water for use in irrigation and classify it by its source. For this purpose, the database generated during the Technology Generation and Adaptation (GAT program was used, in which, as of 1988, water samples were collected monthly from water sources in the states of Paraíba, Rio Grande do Norte and Ceará. To evaluate water quality, the electrical conductivity (EC of irrigation water was taken as a reference, with values corresponding to 0.7 dS m-1. The chemical variables used in this study were: pH, EC, Ca, Mg, Na, K, Cl, HCO3, CO3, and SO4. The data of all characteristics evaluated were standardized and data normality was confirmed by Lilliefors test. Then the irrigation water quality index was determined by an equation that relates the standardized value of the variable with the number of characteristics evaluated. Thus, the IWQI was classified based on indices, considering normal distribution. Finally, these indices were subjected to regression analysis. The method proposed for the IWQI allowed a satisfactory classification of the irrigation water quality, being able to estimate it as a function of EC for the three water sources. Variation in the ionic composition was observed among the three sources and within a single source. Although the water quality differed, it was good in most cases, with the classification IWQI II.

    Full Text Available Objective: To evaluate and describe the sleep quality in seven subscales among the patients with mild traumatic brain injury (TBI and compare it with normal patterns. Methods: This cross-sectional study was conducted within a 6-month period from February to August 2014 in Shahid Rajaei trauma center of Shiraz. Participants were selected randomly from all adult (18-60 years of age patients admitted during the study period with impression of mild TBI (GCS of more than 13. The patients’ sleep quality and demographic characteristics were evaluated by Pittsburgh sleep quality index (PSQI and self- report questionnaire, respectively. Results were compared with normal data, which extracted from the normative data of PSQI manual. Results: Overall we included 60 patients with mild TBI with mean age of 36.2±13.4 years. All the patients had sleep disturbance. Among them there were 46 (76.7% men and 14 (23.3% women. The subjective sleep quality ( p=0.01, sleep latency ( p=0.01, habitual sleep efficiency ( p=0.01, sleep disturbance ( p=0.01, use of sleep medication ( p=0.01 and day time dysfunction ( p=0.01 were significantly impaired in patients with mild TBI when compared to normal values. There were no difference between men and women regarding the sleep quality. The sleep duration was comparable between the subjects and the normal values. Conclusion: Patients with mild TBI have poor sleep quality which should be considered as one of the main factors in interventions after the injury and it might lead to better quality of life.

    There is a consistent relationship between body mass index and sleep quality. However, the directionality and possible confounding factors of this relationship are unclear. Our aim is to confirm the association between sleep quality and body mass index, independent of possible genetic confounding, as well as to provide some indirect inferences about the directionality of this association. The co-twin study design was used to analyse the body mass index-sleep relationship in a sample of 2150 twins. We selected two parallel sub-samples of twins discordant for body mass index (n = 430 pairs), or discordant for sleep quality (n = 316 pairs). Sleep quality and body mass index showed an inverse relationship (b = 0.056, P = 0.032) in the global sample. When twins discordant for body mass index were selected, this association maintained a similar effect size and statistical significance, at all levels of the case-control analysis (all discordant pairs b = 0.173, P body mass index and sleep quality appeared weaker and lost significance (b = 0.021, P = 0.508). The analyses including only dizygotic (b = 0.028, P = 0.526) or monozygotic (b = 0.001, P = 0.984) pairs produced similar non-significant results. Our results confirm the relationship between sleep quality and body mass index, even after applying high levels of control, including genetic factors. Moreover, this study suggests a possible directionality of this relationship, such that sleep quality would strongly affect body mass index, while the opposite would be less robust and consistent in non-clinical samples. © 2017 European Sleep Research Society.

    The behavioral, adaptive and quality of life characteristics of attenuated mucopolysaccharidosis type II (MPS II) have not been well studied. Understanding changes over time in the attenuated phenotype may assist in helping achieve better outcomes in long-term function. This longitudinal study investigates these outcomes in relation to age, somatic disease burden, and IQ. Specifically, somatic disease burden is a major challenge for these patients, even with treatment with enzyme replacement therapy. 15 patients, 10 between ages 6 and MPS II patients have increasing somatic disease burden and poor physical quality of life as they develop as well as decreasing self-esteem and sense of adequacy. Psychosocial quality of life, adaptive skills, and attention improve. Recognition of and intervention around these issues will be beneficial to MPS II attenuated patients who have the resources to use such assistance to improve their long-term outcomes.

    The European Water Framework Directive requires a good ecological status of the European water bodies and the necessary measures to obtain this have to be implemented. The water quality of a river is the result of complex anthropogenic systems (buildings, waste water treatment infrastructure, regulations, etc.) and biogeochemical and eco-hydrological interactions. It is therefore essential to obtain more insight in the factors that determine the water quality in a river. Research into the relation between land use and water quality is necessary. Human activities have a huge impact on the flow regimes and associated water quality of river systems. Effects of land use bound activities on water quality are often investigated, but these studies generally ignore the hydrological complexity of a human influenced catchment. Infrastructure like sewer systems and wastewater treatment plants (WWTP) can displace huge quantities of polluted water. The transfers change flow paths, displace water between catchments and change the residence time of the system. If we want to correctly understand the effect of land use distribution on water quality we have to take these sewer systems into account. In this study we analyse the relation between land use and water quality in the Nete catchment (Belgium) and investigate the impact of the sewage infrastructure on this relation. The Nete catchment (1.673 km²) is a mosaic of semi natural, agricultural and urbanized areas and the land use is very fragmented. For the moment 74% of the households within the catchment are connected to a WWTP. The discharges from these WWTP's compose 15% of the total discharge of the Nete. Based on a runoff model the surface of upstream land use was calculated for 378 points. These data were then corrected for the impact of WWTP's. Using sewage infrastructure plans, urban areas connected to a WWTP were added to the upstream land use of the WWTP's water receiving stream. In order to understand the effect of

    Continuous renal replacement therapy (CRRT) is the preferred renal replacement therapy modality in the critically ill. We aimed to reveal the literature on the pharmacokinetic studies in critically ill patients receiving CRRT with special reference to quality assessment of these studies and the CRRT dose. We conducted a systematic review by searching the MEDLINE, EMBASE, and the Cochrane databases to December 2009 and bibliographies of relevant review articles. We included original studies reporting from critically ill adult subjects receiving CRRT because of acute kidney injury with a special emphasis on drug pharmacokinetics. We used the minimum reporting criteria for CRRT studies by Acute Dialysis Quality Initiative (ADQI) and, second, the Downs and Black checklist to assess the quality of the studies. We calculated the CRRT dose per study. We included pharmacokinetic parameters, residual renal function, and recommendations on drug dosing. Of 182 publications, 95 were considered relevant and 49 met the inclusion criteria. The median [interquartile range (IQR)] number of reported criteria by ADQI was 7.0 (5.0-8.0) of 12. The median (IQR) Downs and Black quality score was 15 (14-16) of 32. None of the publications reported CRRT dose directly. The median (IQR) weighted CRRT dose was 23.7 (18.8-27.9) ml/kg/h. More attention should be paid both to standardizing the CRRT dose and reporting of the CRRT parameters in pharmacokinetic studies. The general quality of the studies during CRRT in the critically ill was only moderate and would be greatly improved by reports in concordant with the ADQI recommendations. © 2011 The Authors Acta Anaesthesiologica Scandinavica © 2011 The Acta Anaesthesiologica Scandinavica Foundation.

    OBJECTIVE: To compare quality of life (QOL) of patients following iatrogenic bile duct injuries (BDI) to matched controls. SUMMARY BACKGROUND DATA: BDI complicate approximately 0.3% of all cholecystectomy procedures. The literature regarding impact on quality of life is conflicted as assessment using clinical determinants alone is insufficient. METHODS: The medical outcomes study short form 36 (SF-36), a sensitive tool for quantification of life quality outcome, was used. The study group of iatrogenic BDI was compared with an age- and sex-matched group who underwent uncomplicated cholecystectomy. Telephone questionnaire using the SF-36 quality of life tool was administered to both groups at a median postoperative time of 12 years 8 months (range, 2 months -20 years). RESULTS: Seventy-eight patients were referred with BDI but due to mortality (n = 10) and unavailability (n = 6) 62 participated. The age- and sex-matched control cohort had undergone uncomplicated cholecystectomy (n = 62). Comparison between groups revealed that 7 of 8 variables examined were statistically similar to those of the control group (physical functioning, role physical, bodily pain, general health perceptions, vitality and social functioning, and mental health index). Mean role emotional scores were slightly worse in the BDI group (46 vs. 50) but the significance was borderline (P = 0.045). Subgroup analysis by method of intervention for BDI did not demonstrate significant differences. CONCLUSION: Quality of life of surviving patients following BDI compares favorably to that after uncomplicated laparoscopic cholecystectomy.

    Full Text Available Many breast cancer survivors have coexistent chronic diseases or comorbidities at the time of their cancer diagnosis. The purpose of the study was to evaluate the association of comorbidities on breast cancer survivors’ quality of life. A prospective design was used to recruit 140 women before cancer surgery, 134 women completed the study. Comorbidities were assessed using self-report and verified by medical record review and the Charlson Comorbidity Index (CCI before and 12-month after cancer surgery. Quality of life was evaluated using Short-Form Health Survey (SF-36 v2. Descriptive statistics, chi-square tests, t-tests, Fisher’s exact test, and correlations were performed for data analysis. A total of 28 comorbidities were identified. Among the 134 patients, 73.8% had at least one of the comorbidities, 54.7% had 2–4, and only 7.4% had 5–8. Comorbidities did not change at 12 months after surgery. Numbers of comorbidities by patients’ self-report and weighted categorization of comorbidities by CCI had a similar negative correlation with overall quality of life scores as well as domains of general health, physical functioning, bodily pain, and vitality. Comorbidities, specifically hypertension, arthritis, and diabetes, were associated with poorer quality of life in multiple domains among breast cancer survivors. Future research should consider the combined influence of comorbidity and cancer on patients’ quality of life.

    Background: The association between quality of work life and participation in knowledge management is unknown. Objectives: This study aimed to discover the association between quality of work life of nurse managers and their participation in implementing knowledge management. Materials and Methods: This was a correlational study. All nurse managers (71 people) from 11 hospitals affiliated with the Social Security Organization in Tehran, Iran, were included. They were asked to rate their participation in knowledge management and their quality of work life. Data was gathered by a researcher-made questionnaire (May-June 2012). The questionnaire was validated by content and construct validity approaches. Cronbach’s alpha was used to evaluate reliability. Finally, 50 questionnaires were analyzed. The answers were scored and analyzed using mean of scores, T-test, ANOVA (or nonparametric test, if appropriate), Pearson’s correlation coefficient and linear regression. Results: Nurse managers’ performance to implement knowledge management strategies was moderate. A significant correlation was found between quality of work life of nurse managers and their participation in implementing knowledge management strategies (r = 0.82; P correlations were found between implementation of knowledge management and participation of nurse managers in decision making (r = 0.82; P < 0.001). Conclusions: Improvement of nurse managers’ work life quality, especially in decision-making, may increase their participation in implementing knowledge management. PMID:25763267

    Studies suggest that the quality of parent-adolescent communication about sex uniquely predicts adolescent sexual behavior. Previous studies have relied predominantly on self-report data. Observational methods, which are not susceptible to self-report biases, may be useful in examining the associations between the quality of parent-adolescent communication about sex and adolescent sexual behavior more objectively. With a sample of adolescents (N = 55, 58% male, 44% white, Mage = 15.8) and their parents, we used hierarchical logistic regression analyses to examine the associations between the observed quality of parent-adolescent communication about dating and sex and the likelihood of adolescents' sexual intercourse. The quality of parent-adolescent communication about dating and sex predicted sexual behavior. Specifically, lecturing was associated with a higher likelihood of adolescents having had sexual intercourse. The quality of parent-adolescent communication about sex is a unique correlate of adolescent sexual behavior and warrants further investigation. Thus, it serves as a potential target of preventive interventions that aim to foster adolescent sexual health behaviors. Copyright © 2015 Society for Adolescent Health and Medicine.

    BACKGROUND Psoriasis is a common, long-term skin disease associated with high levels of psychological distress and a considerable adverse impact on life. The effects of psoriasis, beyond skin affliction, are seldom recognized and often undertreated. OBJECTIVE The aim of the study is to evaluate the quality of life, anxiety and depression, self-esteem and loneliness in patients with psoriasis. METHODS Eighty-four patients with psoriasis were enrolled in the study. The quality of life, depression and anxiety, loneliness and self-esteem of the patient were assessed using the Dermatology Life Quality Index, Hospital Anxiety and Depression Scale, the UCLA loneliness Scale (UCLA-Version 3) and Rosenberg's Self-esteem Scale, respectively. RESULTS The Dermatology Quality of Life Index score among psoriasis patients was 12.61 ± 4.88. They had statistically significantly higher scores according to the Hospital Anxiety and Depression Scale -anxiety subscale (p=0.032)-compared with healthy volunteers. Moreover, a statistically significant difference was found between the two groups concerning the UCLA-scale (p=0.033) and RSES-scale (p<0.0001). Female patients presented with lower self-esteem than male patients. CONCLUSION Psoriasis is a distressing, recurrent disorder that significantly impairs quality of life. Therefore, the recognition and future management of psoriasis may require the involvement of multi-disciplinary teams to manage the physical, psychological and social aspects of the condition, as is the case for systemic, long-term conditions.

    The Hydrologic Simulation Program FORTRAN (HSPF) model was used to assess the impact of wastewater discharges on the water quality of a Lis River tributary (Lena River), a 176 km(2) watershed in Leiria region, Portugal. The model parameters obtained in this study, could potentially serve as reference values for the calibration of other watersheds in the area or with similar climatic characteristics, which don't have enough data for calibration. Water quality constituents modeled in this study included temperature, fecal coliforms, dissolved oxygen, biochemical oxygen demand, total suspended solids, nitrates, orthophosphates and pH. The results were found to be close to the average observed values for all parameters studied for both calibration and validation periods with percent bias values between -26% and 23% for calibration and -30% and 51% for validation for all parameters, with fecal coliforms showing the highest deviation. The model revealed a poor water quality in Lena River for the entire simulation period, according to the Council Directive concerning the surface water quality intended for drinking water abstraction in the Member States (75/440/EEC). Fecal coliforms, orthophosphates and nitrates were found to be 99, 82 and 46% above the limit established in the Directive. HSPF was used to predict the impact of point and nonpoint pollution sources on the water quality of Lena River. Winter and summer scenarios were also addressed to evaluate water quality in high and low flow conditions. A maximum daily load was calculated to determine the reduction needed to comply with the Council Directive 75/440/EEC. The study showed that Lena River is fairly polluted calling for awareness at behavioral change of waste management in order to prevent the escalation of these effects with especially attention to fecal coliforms.

    Full Text Available Background: Well-working health information systems are considered vital with the quality of health data ranked of highest importance for decision making at patient care and policy levels. In particular, health facilities play an important role, since they are not only the entry point for the national health information system but also use health data (and primarily for patient care. Design: A multiple case study was carried out between March and August 2012 at the antenatal care (ANC clinics of two private and one public Kenyan hospital to describe clinical information systems and assess the quality of information. The following methods were developed and employed in an iterative process: workplace walkthroughs, structured and in-depth interviews with staff members, and a quantitative assessment of data quality (completeness and accurate transmission of clinical information and reports in ANC. Views of staff and management on the quality of employed information systems, data quality, and influencing factors were captured qualitatively. Results: Staff rated the quality of information higher in the private hospitals employing computers than in the public hospital which relies on paper forms. Several potential threats to data quality were reported. Limitations in data quality were common at all study sites including wrong test results, missing registers, and inconsistencies in reports. Feedback was seldom on content or quality of reports and usage of data beyond individual patient care was low. Conclusions: We argue that the limited data quality has to be seen in the broader perspective of the information systems in which it is produced and used. The combination of different methods has proven to be useful for this. To improve the effectiveness and capabilities of these systems, combined measures are needed which include technical and organizational aspects (e.g. regular feedback to health workers and individual skills and motivation.

    Background Well-working health information systems are considered vital with the quality of health data ranked of highest importance for decision making at patient care and policy levels. In particular, health facilities play an important role, since they are not only the entry point for the national health information system but also use health data (and primarily) for patient care. Design A multiple case study was carried out between March and August 2012 at the antenatal care (ANC) clinics of two private and one public Kenyan hospital to describe clinical information systems and assess the quality of information. The following methods were developed and employed in an iterative process: workplace walkthroughs, structured and in-depth interviews with staff members, and a quantitative assessment of data quality (completeness and accurate transmission of clinical information and reports in ANC). Views of staff and management on the quality of employed information systems, data quality, and influencing factors were captured qualitatively. Results Staff rated the quality of information higher in the private hospitals employing computers than in the public hospital which relies on paper forms. Several potential threats to data quality were reported. Limitations in data quality were common at all study sites including wrong test results, missing registers, and inconsistencies in reports. Feedback was seldom on content or quality of reports and usage of data beyond individual patient care was low. Conclusions We argue that the limited data quality has to be seen in the broader perspective of the information systems in which it is produced and used. The combination of different methods has proven to be useful for this. To improve the effectiveness and capabilities of these systems, combined measures are needed which include technical and organizational aspects (e.g. regular feedback to health workers) and individual skills and motivation.

    Full Text Available Abstract Background Generic Medicines are an important policy option allowing for access to affordable, essential medicines. Quality of generic medicines must be guaranteed through the activities of national medicines regulatory authorities. Existing negative perceptions surrounding the quality of generic medicines must be addressed to ensure that people use them with confidence. Campaigns to increase the uptake of generic medicines by consumers and providers of healthcare need to be informed by local norms and practices. This study sought to compare South African consumers’ and healthcare providers’ perceptions of quality of generics to the actual quality of selected products. Methods The study was conducted at the local level in three cities of South Africa: Johannesburg, Durban and Cape Town. Purposive sampling was used to recruit consumer participants (n = 73 and random sampling used to recruit healthcare providers from public and private sectors (n = 15. Data were obtained through twelve focus group discussions with consumers and semi-structured interviews (n = 15 with healthcare providers in order to gain familiarity with perceptions of quality. One hundred and thirty five products comprising paracetamol tablets (n = 47, amoxicillin capsules (n = 45 and hydrochlorothiazide tablets (n = 43 were sourced from public and private sector healthcare providers. These products were subjected to in vitro dissolution, uniformity of weight and identity (Fourier Transformed Infrared Spectroscopy tests using prescribed methods from the British (2005 and United States Pharmacopeias (2006. Results Respondents described drug quality in relation to the effect on symptoms. Procurement and use behavior of healthcare providers was influenced by prior experience, manufacturers’ names and consumers’ ability to pay. All formulations passed the in vitro tests for quality. Conclusions This study showed clear differences between

    Full Text Available This performs an empirical investigation to evaluate the relationship between cultural values and earnings quality in some Iranian banks over the period 2005-2011. The individualism, uncertainty avoidance, power distance and masculinity dimensions are regarded as criteria for cultural values. The study also considers change in return on assets and loan loss provisions as the main criteria for earnings quality of banks. For measuring the cultural values, the questionnaire of Hofstede [Hofstede, G. (1994. The business of international business is culture. International business review, 3(1, 1-14.]. The study also uses two measures to calculate earnings quality: 1-just-meet-or-beat the prior year’s earnings and 2- Income smoothing through loan loss provisions based on compound linear regression. Research results showed that there was a weak relationship between cultural values and earnings management.

    2017-09-01

    This study tests whether a personal narrative can persuade people to value comparative data on physician quality. We conducted an online experiment with 850 adults. One group viewed a cartoon narrative on physician quality variation, another saw text on physician quality variation, and there was a control group. Study participants hypothetically selected a physician from a display of four physicians. The top-quality physician was furthest away and most expensive. We conducted multivariate models examining the relationship between experimental group and choice of the top-quality physician. There was no overall relationship between narrative or text information and choice of the highest quality physician. Among higher numerate participants, however, those who viewed the narrative had odds 2.7 times higher of selecting the top-quality physician compared with the control group. Personal narratives can persuade higher numerate people to consider quality when selecting physicians.

    Full Text Available Exposure to electromagnetic field (EMF emitted by mobile phone and other machineries concerns half the world's population and raises the problem of their impact on human health. The present study aims to explore the effects of electromagnetic field exposures on sleep quality and sleep duration among workers from electric power plant.A cross-sectional study was conducted in an electric power plant of Zhejiang Province, China. A total of 854 participants were included in the final analysis. The detailed information of participants was obtained by trained investigators using a structured questionnaire, which including socio-demographic characteristics, lifestyle variables, sleep variables and electromagnetic exposures. Physical examination and venous blood collection were also carried out for every study subject.After grouping daily occupational electromagnetic exposure into three categories, subjects with long daily exposure time had a significantly higher risk of poor sleep quality in comparison to those with short daily exposure time. The adjusted odds ratios were 1.68 (95%CI: 1.18, 2.39 and 1.57 (95%CI: 1.10, 2.24 across tertiles. Additionally, among the subjects with long-term occupational exposure, the longer daily occupational exposure time apparently increased the risk of poor sleep quality (OR (95%CI: 2.12 (1.23∼3.66 in the second tertile; 1.83 (1.07∼3.15 in the third tertile. There was no significant association of long-term occupational exposure duration, monthly electric fee or years of mobile-phone use with sleep quality or sleep duration.The findings showed that daily occupational EMF exposure was positively associated with poor sleep quality. It implies EMF exposure may damage human sleep quality rather than sleep duration.

    Poor sleep quality is a risk factor for a number of cognitive and physiological age-related disorders. Identifying factors underlying sleep quality are important in understanding the etiology of these age-related health disorders. We investigated the extent to which genes and the environment contribute to subjective sleep quality in middle-aged male twins using the classical twin design. We used the Pittsburgh Sleep Quality Index to measure sleep quality in 1218 middle-aged twin men from the Vietnam Era Twin Study of Aging (mean age = 55.4 years; range 51-60; 339 monozygotic twin pairs, 257 dizygotic twin pairs, 26 unpaired twins). The mean PSQI global score was 5.6 [SD = 3.6; range 0-20]. Based on univariate twin models, 34% of variability in the global PSQI score was due to additive genetic effects (heritability) and 66% was attributed to individual-specific environmental factors. Common environment did not contribute to the variability. Similarly, the heritability of poor sleep-a dichotomous measure based on the cut-off of global PSQI>5-was 31%, with no contribution of the common environment. Heritability of six of the seven PSQI component scores (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, and daytime dysfunction) ranged from 0.15 to 0.31, whereas no genetic influences contributed to the use of sleeping medication. Additive genetic influences contribute to approximately one-third of the variability of global subjective sleep quality. Our results in middle-aged men constitute a first step towards examination of the genetic relationship between sleep and other facets of aging. © 2013 European Sleep Research Society.

    Over period of time, the water usage and management is under stress for various reasons including pollution in both surface and subsurface. The groundwater quality decreases due to the solid waste from urban and industrial nodes, rapid use of insecticides and pesticides in agricultural practices. In this study, ground water quality maps for Rupnagar district of Punjab has been prepared using geospatial interpolation technique through Inverse Distance Weighted (IDW) approach. IDW technique has been used for major ground water quality parameters observed from the field samples like Arsenic, Hardness, pH, Iron, Fluoride, TDS, and Sulphate. To assess the ground water quality of the Rupnagar district, total 280 numbers of samples from various sources of tubewells for both pre and post monsoon have collected. Out of which, 80 to 113 samples found Iron with non potable limits ranging 0.3-1.1mg/l and 0.3-1.02mg/l according to BIS standard for both the seasons respectively. Chamkaur Sahib, Rupnagar, Morinda blocks have been found non potable limit of iron in both pre & post-monsoon. 11 to 52 samples in this region have sulphate with permissible limits in both the season ranging 200-400mg/l and 201-400mg/l. But arsenic had acceptable limit in both the season. Various parameters-wise ground water quality map is generated using the range values of drinking water quality to know the distribution of different parameters and diversification in the concentration of different elements. These maps are very much needful for human being to expand awareness among the people to maintain the Cleanness of water at their highest quality and purity levels to achieve a healthy life.

    2017-08-16

    Veterinary clinical trials generate data that advance the transfer of knowledge from clinical research to clinical practice in human and veterinary settings. The translational success of non-regulated and regulated veterinary clinical studies is dependent upon the reliability and reproducibility of the data generated. Clinician-scientists that conduct veterinary clinical studies would benefit from a commitment to research quality assurance and best practices throughout all non-regulated and regulated research environments. Good Clinical Practice (GCP) guidance documents from the FDA provides principles and procedures designed to safeguard data integrity, reliability and reproducibility. While these documents maybe excessive for clinical studies not intended for regulatory oversight it is important to remember that research builds on research. Thus, the quality and accuracy of all data and inference generated throughout the research enterprise remains vulnerable to the impact of potentially unreliable data generated by the lowest performing contributors. The purpose of this first of a series of statement papers is to outline and reference specific quality control and quality assurance procedures that should, at least in part, be incorporated into all veterinary clinical studies.

    2016-01-01

    Introduction Hyperhidrosis (HH) is a condition characterized by excessive sweating or perspiration. General population, especially in developing countries like India are seldom aware of this condition and sparsely seek medical attention. The tropical climate and the environment also influence this condition to a greater extent. This can be a hindrance in their professional and social life. Though, it is a widely explored topic, studies on hyperhidrosis from India are rare. Aim The current study was aimed at estimating the prevalence of hyperhidrosis among college students subjectively and to assess the quality of life using Dermatology Life Quality Index (DLQI). Materials and Methods Five hundred students with age ranging from 17 to 21 years of both genders were included in this study using convenient sampling method. After explaining the study and getting written consent, the students were requested to respond to two questionnaires, one for the subjective diagnosis of hyperhidrosis using a standardized questionnaire developed by North Jersey Thoracic Surgical Associates and the other to assess the quality of life using DLQI. Based on the subjective prevalence scores, the students were divided into 3 groups as “Not bothersome” group, “Somewhat bothersome group” and “Extremely bothersome” group. The DLQI scores of these three groups were compared by ANOVA using SPSS 21.0. Results The study revealed that overall, 38% of the students were suffering from somewhat bothersome to extremely bothersome hyperhidrosis. Gender analysis showed that male students were affected more (58%), especially with palmar hyperhidrosis and were significantly requiring treatment when compared to female students. Analysis of DLQI scores using ANOVA revealed the fact that overall quality of life was significantly affected in almost 35% of students to the extent that they require appropriate treatment and care. Conclusion This study brings into light the higher prevalence of

    To determine whether the quality of press releases issued by medical journals can influence the quality of associated newspaper stories. Retrospective cohort study of medical journal press releases and associated news stories. We reviewed consecutive issues (going backwards from January 2009) of five major medical journals (Annals of Internal Medicine, BMJ, Journal of the National Cancer Institute, JAMA, and New England Journal of Medicine) to identify the first 100 original research articles with quantifiable outcomes and that had generated any newspaper coverage (unique stories ≥100 words long). We identified 759 associated newspaper stories using Lexis Nexis and Factiva searches, and 68 journal press releases using Eurekalert and journal website searches. Two independent research assistants assessed the quality of journal articles, press releases, and a stratified random sample of associated newspaper stories (n=343) by using a structured coding scheme for the presence of specific quality measures: basic study facts, quantification of the main result, harms, and limitations. Proportion of newspaper stories with specific quality measures (adjusted for whether the quality measure was present in the journal article's abstract or editor note). We recorded a median of three newspaper stories per journal article (range 1-72). Of 343 stories analysed, 71% reported on articles for which medical journals had issued press releases. 9% of stories quantified the main result with absolute risks when this information was not in the press release, 53% did so when it was in the press release (relative risk 6.0, 95% confidence interval 2.3 to 15.4), and 20% when no press release was issued (2.2, 0.83 to 6.1). 133 (39%) stories reported on research describing beneficial interventions. 24% mentioned harms (or specifically declared no harms) when harms were not mentioned in the press release, 68% when mentioned in the press release (2.8, 1.1 to 7.4), and 36% when no press release

    Full Text Available Abstract Background While data for preterm children health-related quality of life are available, there are little data on the perception of health-related quality of life evaluation by physicians who manage preterm children, or its use in real life and decision making. The aim of this qualitative study is to highlight among physicians, themes of reflection about health-related quality of life in extremely preterm children (less than 28 weeks’ gestation. Methods Focus groups at a French University Hospital with physicians who manage extremely preterm children: obstetricians, intensive care physicians, neonatal physicians and paediatric neurologists. The focus groups allowed the participants to discuss (drawing on their personal experience, three principal topics regarding the health-related quality of life of preterm children: representation, expectations in daily practice and evaluation method. Results We included fourteen participants in the three focus groups. Many themes emerged from the focus groups: approaches for defining health-related quality of life and difficulties of utilization, the role that health-related quality of life should have in the system of care, the problem of standards and evidence-based decision making. Physicians had difficulties with taking positions regarding this concept. There were no differences by gender, age or seniority, but points of view varied by specialty and type of practice. Physicians who had longer specialized care for extremely preterm children were more sensitive to the impact of preterm complications on health-related quality of life. Conclusions This study provides preliminary results about physicians’ perspective on the health-related quality of life of extremely preterm children. The themes emerged from the focus groups are classically described in other domains but not all in so clear a way (definition, interests and limits, ethical reflection. This approach was never developed in the field

    The Hydrologic Simulation Program FORTRAN (HSPF) model was used to assess the impact of wastewater discharges on the water quality of a Lis River tributary (Lena River), a 176 km{sup 2} watershed in Leiria region, Portugal. The model parameters obtained in this study, could potentially serve as reference values for the calibration of other watersheds in the area or with similar climatic characteristics, which don't have enough data for calibration. Water quality constituents modeled in this study included temperature, fecal coliforms, dissolved oxygen, biochemical oxygen demand, total suspended solids, nitrates, orthophosphates and pH. The results were found to be close to the average observed values for all parameters studied for both calibration and validation periods with percent bias values between − 26% and 23% for calibration and − 30% and 51% for validation for all parameters, with fecal coliforms showing the highest deviation. The model revealed a poor water quality in Lena River for the entire simulation period, according to the Council Directive concerning the surface water quality intended for drinking water abstraction in the Member States (75/440/EEC). Fecal coliforms, orthophosphates and nitrates were found to be 99, 82 and 46% above the limit established in the Directive. HSPF was used to predict the impact of point and nonpoint pollution sources on the water quality of Lena River. Winter and summer scenarios were also addressed to evaluate water quality in high and low flow conditions. A maximum daily load was calculated to determine the reduction needed to comply with the Council Directive 75/440/EEC. The study showed that Lena River is fairly polluted calling for awareness at behavioral change of waste management in order to prevent the escalation of these effects with especially attention to fecal coliforms. - Highlights: • An integrated hydrological and water quality model for river management is presented. • An insight into the

    Background. Only some studies provide sufficient data regarding the effects of nonpostbariatric (aesthetic) abdominoplasty on various aspects of quality of life. Nevertheless, when considering the effects on eating habits, publications are lacking. Therefore we decided to assess the effects of nonpostbariatric abdominoplasty on eating disorder symptoms, psychological distress, and quality of life. Materials and Methods. 64 consecutive women underwent nonpostbariatric abdominoplasty. Three outcome measures were completed: the Eating Disorder Inventory (EDI), Raitasalo's modification of the Beck Depression Inventory (RBDI), and the 15D general quality of life questionnaire. Results. The mean age at baseline was 42 years and the mean body mass index (BMI) 26.4. Fifty-three (83%) women completed all the outcome measures with a mean follow-up time of 5 months. A significant improvement from baseline to follow-up was noted in women's overall quality of life, body satisfaction, effectiveness, sexual functioning, and self-esteem. The women were significantly less depressive and had significantly less drive for thinness as well as bulimia, and their overall risk of developing an eating disorder also decreased significantly. Conclusions. Abdominoplasty results in significantly improved quality of life, body satisfaction, effectiveness, sexual functioning, self-esteem, and mental health. The risk of developing an eating disorder is decreased significantly. This trial is registered with Clinicaltrials.gov NCT02151799.

    Based on data collected from an exercise app, the study aims to provide empirical evidence on the relationship between air quality and patterns of outdoor exercise in China. Objective outdoor exercise data spanning 160 days were collected from 153 users of an exercise app, Tulipsport in China. Each exercise mode (running, biking, and walking, respectively) was organized into five air quality categories based on Air Quality Index (AQI): excellent, good, mild pollution, moderate pollution, and serious pollution. Key parameters of each app user were calculated and analyzed: the total number of exercise bouts, the average duration, and the average distance of each exercise mode in each air quality category. Multivariate analyses of variance indicate that the users were less likely to participate in outdoor running, biking, and walking (F = 24.16, p air pollution increased. However, there is no difference in terms of average distance and duration of exercise across different air pollution categories. People's participation in outdoor exercise is impeded by air pollution severity, but they stick to their exercise routines once exercise is initiated. Although people should protect themselves from health damages caused by exercising under pollution, the decreases in physical activity associated with air pollution may also pose an indirect risk to public health. The interactive relationship between air quality, exercise, and health warrants more empirical and interdisciplinary explorations.

The methodology used combined basic and new quality tools in order to identify, classify and analyse the main problems according to their priority (weight of importance. The tools used were Pareto Chart, Brainstorming,Fishbone Diagram and Matrix diagram. The company where the study was carried out was the Ken Tire Industrial Complex, which is one of the biggest Tire Retreading Companies in Middle East. The data was collected during all the year of 2009 from quality and production records. The main problems were classified according the cost of defects that happen during the production process and the use of appropriate improvement quality tools is proposed in order to minimize the impact of defect causes in final products and semi-products.

    Full Text Available Analysis of the current literature showed that in publications, in our opinion, there is no master: a scientific analysis of the reasons behind the decline in the quality of knowledge of the doctor, as well as the scientific basis of modern pedagogical technologies introduced in the process of training future doctors to address this problem. Objective and subjective factors are having a negative effect on the quality of the doctor's knowledge. The generally accepted methods of assessing the quality of knowledge – testing and rating system – have their limitations. Testing reflects the level of knowledge about the thinking style of the originator of test tasks. Ranking system for assessing knowledge increasingly characterized by diligence in studying medicine. It is proposed to upgrade the quality of medical knowledge in the teaching of the theory of integration of diagnostics. Amount of knowledge to evaluate the content of educational narrative history of the disease. The quality of the knowledge to assess the content of professional clinical picture comment in the history of the disease.

    Full Text Available Volunteer geographical information (VGI, either in the context of citizen science or the mining of social media, has proven to be useful in various domains including natural hazards, health status, disease epidemics, and biological monitoring. Nonetheless, the variable or unknown data quality due to crowdsourcing settings are still an obstacle for fully integrating these data sources in environmental studies and potentially in policy making. The data curation process, in which a quality assurance (QA is needed, is often driven by the direct usability of the data collected within a data conflation process or data fusion (DCDF, combining the crowdsourced data into one view, using potentially other data sources as well. Looking at current practices in VGI data quality and using two examples, namely land cover validation and inundation extent estimation, this paper discusses the close links between QA and DCDF. It aims to help in deciding whether a disentanglement can be possible, whether beneficial or not, in understanding the data curation process with respect to its methodology for future usage of crowdsourced data. Analysing situations throughout the data curation process where and when entanglement between QA and DCDF occur, the paper explores the various facets of VGI data capture, as well as data quality assessment and purposes. Far from rejecting the usability ISO quality criterion, the paper advocates for a decoupling of the QA process and the DCDF step as much as possible while still integrating them within an approach analogous to a Bayesian paradigm.

    Abstract: Changes in the milling quality, chemical characteristics, eating qualityand dynamic viscoelasticities of seven cultivars of japoinica rice after about eightmonths storage at room temperature were studied. Comparisons between new andstored rices showed that no obvious changes in milling quality, amylose and proteincontent were found. Though there was varietal difference, the palatability of allcultivars deteriorated with storage.The overall eating quality of Koshihikari andEtsunan162 stored rice were almost the same as that of new rice of Nihonbare andXiushui11. The deterioration in palatability was due to the deterioration of theappearance, taste and stickiness of cooked rice. New rice grain from cultivars witha good eating quality showed a relatively high palatability as compare with storedrice. The moduli of cooked rice grains of stored rice were increased and values ofloss tangent of cooked rice was lower than those of new rice, such cases in poorpalatability cultivars were much more obvious. The eating quality of stored rice wasgenerally poor for the cultivars with a high free fatty acid content. In addition, thebreakdown and maximum viscosity values in amylographic characteristics wereslightly increased.

  16. COMPETENCY-BASED PAY AND SERVICE QUALITY: AN EMPIRICAL STUDY OF MALAYSIAN PUBLIC ORGANISATIONS

    Full Text Available A higher number of complaints have been filed by the public due to delays by public sectors in taking action and providing services to the public. This suggests that service quality is not being delivered as expected by customers. With competency-based pay being offered in the public sector under the System Saraan Malaysia (SSM, which aims to produce capable workers who are responsive to customers' demands by providing quality services, one would expect that there would be an improvement in the general quality of the services rendered. Thus, this research aimed to investigate the relationship between the extent of competency-based pay practices and service quality. The findings suggest that there is a positive relationship between competency-based pay practices and service provision, one of the SERVQUAL dimensions found in this study. Thus, Malaysian public organisations should offer this type of pay as frequently as possible in order to motivate civil servants to provide quality services to the public.

  17. Field Scale Studies on the Spatial Variability of Soil Quality Indicators in Washington State, USA

    Full Text Available Arable lands are needed for sustainable agricultural systems to support an ever-growing human population. Soil quality needs to be defined to assure that new land brought into crop production is sustainable. To evaluate soil quality, a number of soil attributes will need to be measured, evaluated, and integrated into a soil-quality index using the multivariable indicator kriging (MVIK procedure. This study was conducted to determine the spatial variability and correlation of indicator parameters on a field scale with respect to soil quality and suitability for use with MVIK. The variability of the biological parameters decreased in the order of respiration > enzyme assays and qCO2 > microbial biomass C. The distribution frequency of all parameters except respiration were normal although the spatial distribution across the landscape was highly variable. The biological parameters showed little correlation with each other when all data points were considered; however, when grouped in smaller sections, the correlations were more consistent with observed patterns across the field. To accurately assess soil quality, and arable land use, consideration of spatial and temporal variability, soil conditions, and other controlling factors must be taken into account.

    This contribution assesses the performance of national education systems along two important dimensions: The degree to which they help individuals develop capabilities necessary for their successful social integration (educational quality) and the degree to which they confer equal opportunities for social advancement (educational equality). It advances a new conceptualization to measure quality and equality in education and then uses it to study the relationship between institutional differentiation and these outcomes. It relies on data on final educational credentials and literacy among adults that circumvent some of the under-appreciated conceptual challenges entailed in the widespread analysis of international student assessment data. The analyses reveal a positive relationship between educational quality and equality and show that education systems with a lower degree of institutional differentiation not only provide more educational equality but are also marked by higher levels of educational quality. While the latter association is partly driven by other institutional and macro-structural factors, I demonstrate that the higher levels of educational equality in less differentiated education systems do not entail an often-assumed trade-off for lower quality.

    Genetic counselling for presymptomatic testing is complex, bringing both ethical and practical questions. There are protocols for counselling but a scarcity of literature regarding quality assessment of such counselling practice. Generic quality assessment tools for genetic services are not specific to presymptomatic testing (PST). Therefore, the aim of this study was to identify aspects of effective counselling practice in PST for late-onset neurological disorders. We used the Delphi method to ascertain the views of relevant European experts in genetic counselling practice, ascertained via published literature and nomination by practitioners. Ethical approval was obtained. Questionnaires were sent electronically to a list of 45 experts, (Medical Doctors, Geneticists, Genetic Counsellors and Genetic Nurses), who each contributed to one to three rounds. In the first round, we provided a list of relevant indicators of quality of practice from a literature review. Experts were requested to evaluate topics in four domains: (a) professional standards; (b) service standards; (c) the consultant's perspective; and (d) protocol standards. We then removed items receiving less than 65% approval and added new issues suggested by experts. The second round was performed for the refinement of issues and the last round was aimed at achieving final consensus on high-standard indicators of quality, for inclusion in the assessment tool. The most relevant indicators were related to (1) consultant-centred practice and (2) advanced counselling and interpersonal skills of professionals. Defined high-standard indicators can be used for the development of a new tool for quality assessment of PST counselling practice.

    Sleep and sleep disorders are related to cardiovascular disease, and microvascular function is an early cardiovascular disease marker. Therefore, the relationship of sleep (measured in sleep quality and duration) with microvascular function was examined in healthy adults. Sleep quality was assessed with the validated Sleep Wake Experience List (SWEL) questionnaire. Duration of sleep was self-reported in an additional question. Microvascular function was measured using nailfold capillaroscopy. Linear regression analyses were used to examine the relationship between sleep and microvascular function. Potential confounders included physical activity, smoking, blood pressure, body mass index and several biochemical parameters. Analyses were performed in 259 participants (116 men). For women reporting insufficient (sleep duration, microvascular function (post-ischaemic capillary recruitment) was significantly lower (b = -11.17; P = 0.04) compared to women reporting sufficient sleep duration. There was no relationship between sleep quality and microvascular function in females. In males, a trend towards lower capillary recruitment was found in those reporting a combination of poor sleep quality and insufficient duration (b = -7.54; P = 0.09), compared to those reporting good sleep quality as well as sufficient duration. This study suggests an association between sleep and microvascular function. Which aspects of sleep exactly affect microvascular function, and if indeed the association is different between males and females in other samples, needs further research.
