This document of Data Quality Objectives (DQOs) was prepared based on the U.S. Environmental Protection Agency (EPA) Guidance on Systematic Planning Using the Data Quality Objectives Process, EPA, QA/G4, 2/2006 (EPA 2006) as well as several other published DQOs. Pacific Northwest National Laboratory (PNNL) is in the process of developing a radiological air monitoring program for the PNNL Site that is distinct from that of the nearby Hanford Site. Radiological emissions at the PNNL Site result from Physical Sciences Facility (PSF) major emissions units. A team was established to determine how the PNNL Site would meet federal regulations and address guidelines developed to monitor and estimate offsite air emissions of radioactive materials. The result is a program that monitors the impact to the public from the PNNL Site.

Full Text Available The quality of an image produced by the Whole Slide Imaging (WSI scanners is of critical importance for using the image in clinical diagnosis. Therefore, it is very important to monitor and ensure the quality of images. Since subjective image quality assessments by pathologists are very time-consuming, expensive and difficult to reproduce, we propose a method for objective assessment based on clinically relevant and perceptual image parameters: sharpness, contrast, brightness, uniform illumination and color separation; derived from a survey of pathologists. We developed techniques to quantify the parameters based on content-dependent absolute pixel performance and to manipulate the parameters in a predefined range resulting in images with content-independent relative quality measures. The method does not require a prior reference model. A subjective assessment of the image quality is performed involving 69 pathologists and 372 images (including 12 optimal quality images and their distorted versions per parameter at 6 different levels. To address the inter-reader variability, a representative rating is determined as a one-tailed 95% confidence interval of the mean rating. The results of the subjective assessment support the validity of the proposed objective image quality assessment method to model the readers’ perception of image quality. The subjective assessment also provides thresholds for determining the acceptable level of objective quality per parameter. The images for both the subjective and objective quality assessment are based on the HercepTestTM slides scanned by the Philips Ultra Fast Scanners, developed at Philips Digital Pathology Solutions. However, the method is applicable also to other types of slides and scanners.

Setting priorities for ambient air quality objectives

International Nuclear Information System (INIS)

2004-10-01

Alberta has ambient air quality objectives in place for several pollutants, toxic substances and other air quality parameters. A process is in place to determine if additional air quality objectives are required or if existing objectives should be changed. In order to identify the highest priority substances that may require an ambient air quality objective to protect ecosystems and public health, a rigorous, transparent and cost effective priority setting methodology is required. This study reviewed, analyzed and assessed successful priority setting techniques used by other jurisdictions. It proposed an approach for setting ambient air quality objective priorities that integrates the concerns of stakeholders with Alberta Environment requirements. A literature and expert review were used to examine existing priority-setting techniques used by other jurisdictions. An analysis process was developed to identify the strengths and weaknesses of various techniques and their ability to take into account the complete pathway between chemical emissions and damage to human health or the environment. The key strengths and weaknesses of each technique were identified. Based on the analysis, the most promising technique was the tool for the reduction and assessment of chemical and other environmental impacts (TRACI). Several considerations for using TRACI to help set priorities for ambient air quality objectives were also presented. 26 refs, 8 tabs., 4 appendices

The Hanford Generating Plant (HGP) consists of two 430 MW low-pressure turbine generators and is owned by the Washington Public Power Supply System (WPPSS). Steam from the N Reactor powered the HGP turbines before passing through the turbine condenser, where waste heat was transferred to the cooling water. The DOE-RL requested that Environmental Restoration Contractor (ERC) generate a sampling and analysis plan to assist in the assessment of decontamination and decommissioning (D and D) and remediation of the HGP and 11 associated Solid Waste Management Units (SWMUs). This report summarizes the results of the Data Quality Objectives planning process as applied to HGP. The characterization data will be used to better estimate the cost for D and D and remediation. These costs will be utilized in an agreement between the Department of Energy-Richland Office (DOE-RL) and the WPSS. The agreement will define which organization will perform D and D of the HGP building, external support buildings, and remediation of buildings and soils surrounding the facility. The sampling and analysis design is presented in Section 7 with Tables 7-1 and 7-3 summarizing the design, number, location, analytes, and analytical methods to be used. The purpose of the sampling is to provide the nature and depth of contaminants. In locations where it was difficult to make assumptions related to extent, the design allows for limited characterization related to extent of contamination

Full Text Available The research discusses the use of artificial neural networks (ANN as components of a decision support system (DSS to automate quality control manufacturing facilities machining business at the production, which should be focused on the analysis of large amounts of heterogeneous information. The necessity to use ANN as a part of DSS is justified by the fact that quality control during production is multistage and time-consuming process that is formalized difficult, and moreover requires considerable information and material costs for the efficiency of manufacturing operations performed. Taking into account the existing experience of successful use of ANN to solve difficult formal problems associated with handling large volumes of diverse and rapidly changing information, the authors synthesized ANN for automated determination of the causes deterioration of the quality of production objects (PO in the performance of manufacturing operations application. Particular attention is paid to the definition of the dimension of the hidden layer ANN synthesized due to the fact that today still there is no analytical expression to determine the dimension of the hidden layer ANN and size of the latter is determined only by the experimental results of ANN several different structures by comparison the results, in particular the value of mean square error.
Data quality objective to support resolution of the organic complexant safety issue

International Nuclear Information System (INIS)

Turner, D.A.; Babad, H.; Buckley, L.L.; Meacham, J.E.

1995-01-01

This document records the data quality objectives (DQO) process applied to the organic complexant safety issue at the Hanford Site. Two important outputs of this particular DQO application were the following: (1) decision rules for categorizing organic tanks; and (2) analytical requirements that feed into the tank-specific characterization plans. The decision rules developed in this DQO allow the organic tanks to be categorized as safe, conditionally safe, or unsafe based on fuel and moisture concentrations. Then analytical requirements from this DQO process fall into two groups, primary and secondary. The primary data requirements are always applied, while the secondary requirements are only necessary on those half segment samples that violate the fuel and moisture decision rules or that propagate during adiabatic calorimetry testing

Chen, Jacqueline M; Kim, Heejung S; Sherman, David K; Hashimoto, Takeshi

Emotional expression is highly valued in individualistic cultures, whereas emotional restraint is prioritized in collectivistic cultures. We hypothesized that high-quality relationships in these cultures would exhibit the forms of support provision congruent with their respective expectations. Study 1 examined support transactions among friends in response to a laboratory stressor and found that objectively judged relationship quality (RQ) more strongly positively predicted emotion-focused support provision behaviors by European Americans than by Asian Americans. Study 2, a questionnaire study, found that self-reported RQ predicted emotion-focused support provision more strongly among European Americans than among Japanese. Study 3 investigated more indirect forms of support and found that RQ more strongly predicted worrying about and monitoring close others enduring stressors and spending time with them without talking about the stressor among Asian Americans compared with European Americans. These findings suggest that RQ is expressed in terms of support provision in culturally normative ways. © 2015 by the Society for Personality and Social Psychology, Inc.
Data Quality Objectives Summary Report Supporting Radiological Air Surveillance Monitoring for the INL Site

Haney, Thomas Jay [Idaho National Lab. (INL), Idaho Falls, ID (United States)

2015-05-01

This report documents the Data Quality Objectives (DQOs) developed for the Idaho National Laboratory (INL) Site ambient air surveillance program. The development of the DQOs was based on the seven-step process recommended “for systematic planning to generate performance and acceptance criteria for collecting environmental data” (EPA 2006). The process helped to determine the type, quantity, and quality of data needed to meet current regulatory requirements and to follow U.S. Department of Energy guidance for environmental surveillance air monitoring design. It also considered the current air monitoring program that has existed at INL Site since the 1950s. The development of the DQOs involved the application of the atmospheric dispersion model CALPUFF to identify likely contamination dispersion patterns at and around the INL Site using site-specific meteorological data. Model simulations were used to quantitatively assess the probable frequency of detection of airborne radionuclides released by INL Site facilities using existing and proposed air monitors.

The U.S. Environmental Protection Agency (EPA) spends about $500 million annually in collecting environmental data for scientific research and regulatory decision making. In addition, the regulated community may spend as much as ten times more each year in responding to EPA compliance requirements. Among the EPA and the regulated community there are several important common concerns: both want to make informed decisions using the right type, quality, and quantity of data. Collecting new data is very resource intensive to all parties. Neither EPA nor the regulated community can afford to collect more or {open_quotes}better{close_quotes} data than are really needed; the Data Quality Objectives (DQO) process is a systematic planning tool for ensuring that the right data will be collected for arriving at a decision within the desired confidence constraints.

Sensory evaluation is one of the most important methods for assessing freshness and quality in the fish sector and in fish-inspection services. Sensory methods performed in a proper way are a rapid and accurate tool providing unique information about food. Traditionally, sensory methods have been...... seen as a subjective assessment of quality. However, sensory methods can be turned into an objective tool. European fisheries research institutes have developed such a tool, by which sensory assessment is performed in a systematic way with an objective quality assessment method called the Quality Index...... Method (QIM). It is foreseen that the QIM will be useful to give feedback to fishermen concerning the quality of their catch, which may in turn influence better handling on board. The QIM is a promising method for quick and reliable assessment of the freshness of fish. It is expected to become...

Full Text Available Tracking occluded objects at different depths has become as extremely important component of study for any video sequence having wide applications in object tracking, scene recognition, coding, editing the videos and mosaicking. The paper studies the ability of annotation to track the occluded object based on pyramids with variation in depth further establishing a threshold at which the ability of the system to track the occluded object fails. Image annotation is applied on 3 similar video sequences varying in depth. In the experiment, one bike occludes the other at a depth of 60cm, 80cm and 100cm respectively. Another experiment is performed on tracking humans with similar depth to authenticate the results. The paper also computes the frame by frame error incurred by the system, supported by detailed simulations. This system can be effectively used to analyze the error in motion tracking and further correcting the error leading to flawless tracking. This can be of great interest to computer scientists while designing surveillance systems etc.

Quality of life and needforsocial support in persons diagnosed with multiple sclerosis (MS) are to a large extent determined by the degree of their disability. The aim of the study was to analyze an association between specific forms of MS, subjectively perceived quality of life and social support. The study included subjects with established diagnosis of MS, treated at rehabilitation centers, hospitals and in a home setting, as well as the members of patient organizations. After being informed about objectives of the study, type of included tasks and way to complete them, each participant was handed out a set of questionnaires: Berlin Social Support Scales (Łuszczyńska, Kowalska, Schwarzer, Schulz), Quality of Life Questionnaire (WHOQOLBREF), as well as a survey developed specifically for the purposes of this project. The results were subjected to statistical analysis with STATA 12 package. The study included a total of 110 persons (67 women and 43 men). Quality of life overall, as well in physical, psychological, social relationships and environmental health domains, turned out to be particularly important in patients with primary-progressive MS. Irrespective of MS type, social support overall did not play a significant role on univariate analysis. However, subgroup analysis according to sex demonstrated that men with MS received social support four times less often than women. Quality of life in individuals with primary-progressive MS is significantly lower than in patients presenting with other types of this disease. Men with MS are more likely to present with worse scores for social support overall. They are less likely both to acknowledge the need for support and to realize the availability of support they actually need.

There are 177 waste storage tanks containing over 210,000 m 3 (55 million gal) of mixed waste at the Hanford Site. The River Protection Project (RPP) has adopted the data quality objective (DQO) process used by the U.S. Environmental Protection Agency (EPA) (EPA 1994a) and implemented by RPP internal procedure (Banning 1999a) to identify the information and data needed to address safety issues. This DQO document is based on several documents that provide the technical basis for inputs and decision/action levels used to develop the decision rules that evaluate the transfer of wastes. A number of these documents are presently in the process of being revised. This document will need to be revised if there are changes to the technical criteria in these supporting documents. This DQO process supports various documents, such as sampling and analysis plans and double-shell tank (DST) waste analysis plans. This document identifies the type, quality, and quantity of data needed to determine whether transfer of supernatant can be performed safely. The requirements in this document are designed to prevent the mixing of incompatible waste as defined in Washington Administrative Code (WAC) 173-303-040.

Context aware systems are able to adapt their behavior according to the environment in which the user is. They can be integrated into an Internet of Things (IoT) infrastructure, allowing a better perception of the user's physical environment by collecting context data from sensors embedded in devices known as smart objects. An IoT extension called the Internet of Mobile Things (IoMT) suggests new scenarios in which smart objects and IoT gateways can move autonomously or be moved easily. In a comprehensive view, Quality of Context (QoC) is a term that can express quality requirements of context aware applications. These requirements can be those related to the quality of information provided by the sensors (e.g., accuracy, resolution, age, validity time) or those referring to the quality of the data distribution service (e.g, reliability, delay, delivery time). Some functionalities of context aware applications and/or decision-making processes of these applications and their users depend on the level of quality of context available, which tend to vary over time for various reasons. Reviewing the literature, it is possible to verify that the quality of context support provided by IoT-oriented middleware systems still has limitations in relation to at least four relevant aspects: (i) quality of context provisioning; (ii) quality of context monitoring; (iii) support for heterogeneous device and technology management; (iv) support for reliable data delivery in mobility scenarios. This paper presents two main contributions: (i) a state-of-the-art survey specifically aimed at analyzing the middleware with quality of context support and; (ii) a new middleware with comprehensive quality of context support for Internet of Things Applications. The proposed middleware was evaluated and the results are presented and discussed in this article, which also shows a case study involving the development of a mobile remote patient monitoring application that was developed using the

1995-01-01

This Data Quality Objective (DQO) document presents the data needs and accuracy requirements for sampling ion exchange modules at the K Basins, 100 K Area, to determine if there is a hydrogen gas buildup within the modules. This document was produced by PNL, with the assistance of Neptune and Associates, and was partly funded (for facilitator) by DOE-HQ as a demonstration DQO for EM activities. PNL involved a number of PNL, WHC and support contract staff (including external technical consultants) in meetings to define the data needed, along with the necessary accuracy, to resolve issues associated with hydrogen accumulation in Ion Exchange Modules (IXMS) that were generated prior to July 1994 and only have one nuc-fil vent. IXMs generated after July 1994 have multiple nuc-fil vents and do not require sampling. PNL transmitted this DQO to WHC on January 31, 1995. This Supporting Document is to assure that the document is captured into the document retrieval system. WHC review focused on the acceptability of the technical conclusions such that the data collected will meet minimum operational, safety and environmental needs

1994-01-01

The Tank Waste Remediation System (TWRS) is responsible for storing, processing, and immobilizing the Hanford Site tank wastes. Characterization information on the tank wastes is needed so that safety concerns can be addressed, and retrieval, pretreatment, and immobilization processes can be designed, permitted, and implemented. This document describes the near-term tank waste sampling and characterization needs of the Pretreatment, High-Level Waste (HLW) Disposal, and Low-Level Waste (LLW) Disposal Programs to support the TWRS disposal mission. The final DQO (Data Quality Objective) will define specific waste tanks to be sampled, sample timing requirements, an appropriate analytical scheme, and a list of required analytes. This interim DQO, however, focuses primarily on the required analytes since the tanks to be sampled in FY 1994 and early FY 1995 are being driven most heavily by other considerations, particularly safety. The major objective of this Interim DQO is to provide guidance for tank waste characterization requirements for samples taken before completion of the final DQO. The characterization data needs defined herein will support the final DQO to help perform the following: Support the TWRS technical strategy by identification of the chemical and physical composition of the waste in the tanks and Guide development efforts to define waste pretreatment processes, which will in turn define HLW and LLW feed to vitrification processes

Full Text Available At present, information technologies (IT are intensively used all over the world in various sectors, and today medical institutions cannot do without them when organizing the process of medical diagnostic. The IT efficiency is determined by the degree of their intellectualization that is by including knowledge bases as their component and by the transition from data processing to the processing of knowledge. The efficiency of making decisions in various areas of activity is determined by the quality and quick delivery of information. Medicine constitutes no exception in this sense. The advanced level of computer technology, applied tools, diagnostics on the basis of automated systems of decision support made it possible to solve the tasks of assessing the state of the object at a qualitatively new level. The subject matter of this study is to ensure the mathematical support of the intelligent information system (IS of assessing the state of the object. The object is understood as a patient who came through a myocardial infarction (MI. The goal of the study is to develop mathematical support of the intelligent IS of assessing and predicting a patient’s condition. To achieve the stated goal, the following tasks were solved: statistically valid and uncorrelated signs were specified; these signs enable distinguishing the group of patients who survived from those who died, “decisive rules” were formulated for predicting the MI clinical outcome. In the process of the study, the mathematical IT of assessing the state of the object was developed. The following result was obtained: the suggested mathematical models for predicting the outcome of myocardial infarction that were developed with the use of the method of discriminant function and took into account human blood values can prevent sudden coronary death and improve the diagnostic efficiency. Conclusions. Mathematical models were developed to predict the state of the object in the event of
Multi-objective calibration of a reservoir water quality model in aggregation and non-dominated sorting approaches

Numerical water quality models are developed to predict contaminant fate and transport in receiving waters such as reservoirs and lakes. They can be helpful tools for water resource management. The objective of this study is to calibrate a water quality model which was set up to simulate the water quality conditions of Pepacton Reservoir, Downsville, New York, USA, using an aggregation hybrid genetic algorithm (AHGA) and a non-dominated sorting hybrid genetic algorithm (NSHGA). Both AHGA and NSHGA use a hybrid genetic algorithm (HGA) as optimization engines but are different in fitness assignment. In the AHGA, a weighted sum of scaled simulation errors is designed as an overall objective function to measure the fitness of solutions (i.e., parameter values). In the NSHGA, a method based on non-dominated sorting and Euclidean distances is proposed to calculate the dummy fitness of solutions. In addition, this study also compares the AHGA and the NSHGA. The purpose of this comparison is to determine whether the objective function values (i.e., simulation errors) and simulated results obtained by the AHGA and the NSHGA are significantly different from each other. The results show that the objective function values from the two HGAs are good compromises between all objective functions, and the calibrated model results match the observed data reasonably well and are comparable to other studies, supporting and justifying the use of multi-objective calibration.

Watanabe, Keishiro; Okamoto, Jun; Kurita, Takaaki

2006-01-01

With the development of the broadband network, video communications such as videophone, video distribution, and IPTV services are beginning to become common. In order to provide these services appropriately, we must manage them based on subjective video quality, in addition to designing a network system based on it. Currently, subjective quality assessment is the main method used to quantify video quality. However, it is time-consuming and expensive. Therefore, we need an objective quality assessment technology that can estimate video quality from video characteristics effectively. Video degradation can be categorized into two types: spatial and temporal. Objective quality assessment methods for spatial degradation have been studied extensively, but methods for temporal degradation have hardly been examined even though it occurs frequently due to network degradation and has a large impact on subjective quality. In this paper, we propose an objective quality assessment method for temporal degradation. Our approach is to aggregate multiple freeze distortions into an equivalent freeze distortion and then derive the objective video quality from the equivalent freeze distortion. Specifically, our method considers the total length of all freeze distortions in a video sequence as the length of the equivalent single freeze distortion. In addition, we propose a method using the perceptual characteristics of short freeze distortions. We verified that our method can estimate the objective video quality well within the deviation of subjective video quality.
Tank safety screening data quality objective. Revision 1

Energy Technology Data Exchange (ETDEWEB)

Hunt, J.W.

1995-04-27

The Tank Safety Screening Data Quality Objective (DQO) will be used to classify 149 single shell tanks and 28 double shell tanks containing high-level radioactive waste into safety categories for safety issues dealing with the presence of ferrocyanide, organics, flammable gases, and criticality. Decision rules used to classify a tank as ``safe`` or ``not safe`` are presented. Primary and secondary decision variables used for safety status classification are discussed. The number and type of samples required are presented. A tabular identification of each analyte to be measured to support the safety classification, the analytical method to be used, the type of sample, the decision threshold for each analyte that would, if violated, place the tank on the safety issue watch list, and the assumed (desired) analytical uncertainty are provided. This is a living document that should be evaluated for updates on a semiannual basis. Evaluation areas consist of: identification of tanks that have been added or deleted from the specific safety issue watch lists, changes in primary and secondary decision variables, changes in decision rules used for the safety status classification, and changes in analytical requirements. This document directly supports all safety issue specific DQOs and additional characterization DQO efforts associated with pretreatment and retrieval. Additionally, information obtained during implementation can assist in resolving assumptions for revised safety strategies, and in addition, obtaining information which will support the determination of error tolerances, confidence levels, and optimization schemes for later revised safety strategy documentation.

METHOD OF IMAGE QUALITY ENHANCEMENT FOR SPACE OBJECTS

Directory of Open Access Journals (Sweden)

D. S. Korshunov

2014-07-01

Full Text Available The paper deals with an approach for image quality improvement of the space objects in the visible range of electromagnetic wave spectrum. The proposed method is based on the joint taking into account of both the motion velocity of the space supervisory apparatus and a space object observed in the near-earth space when the time of photo-detector exposure is chosen. The timing of exposure is carried out by light-signal characteristics, which determines the optimal value of the charge package formed in the charge-coupled device being irradiated. Thus, the parameters of onboard observation equipment can be selected, which provides space images suitable for interpretation. The linear resolving capacity is used as quality indicator for space images, giving a complete picture for the image contrast and geometric properties of the object on the photo. Observation scenario modeling of the space object, done by sputnik-inspector, has shown the possibility of increasing the linear resolution up to10% - 20% or up to 40% - 50% depending on the non-complanarity angle at the movement along orbits. The proposed approach to the increase of photographs quality provides getting sharp and highcontrast images of space objects by the optical-electronic equipment of the space-based remote sensing. The usage of these images makes it possible to detect in time the space technology failures, which are the result of its exploitation in the nearearth space. The proposed method can be also applied at the stage of space systems design for optical-electronic surveillance in computer models used for facilities assessment of the shooting equipment information tract.

Hospitals frequently evaluate their service quality based on the care and services provided to patients by their clinical and non-clinical staff.(1,2) However, such evaluations do not take into consideration the many interactions that patients have in online patient communities with the health-care organization (HCO) as well as with peer patients. Patients' interactions in these online communities could impact their perceptions regarding the HCO's service quality. The objective of this pilot study was to evaluate the impact of social support and responsiveness that patients experience in an HCO's online community on patients' perceptions regarding the HCO's service quality. The study data are collected from CHESS, a health-care programme (Comprehensive Health Enhancement Support System) run by the Centre for Health Enhancement System Studies at the University of Wisconsin-Madison. Findings show that the social support and the responsiveness received from peer patients in the online patient communities will impact patients' perceptions regarding the service quality of the HCO even when the organizational members themselves do not participate in the online discussions. The results indicate that interactions in such HCO-provided online patient communities should not be ignored as they could translate into patients' perceptions regarding HCOs' service quality. Ways to improve responsiveness and social support in an HCO's online patient community are discussed. © 2014 John Wiley & Sons Ltd.

Full Text Available Background: When people face health problems, their life satisfaction levels and social relations could be ruined. When it comes to an eerie, deadly and chronic disease like cancer, the individual is much more likely to be affected by it. Objective: This descriptive study aims to identify quality of life and level of social support and the affecting factors in cancer patients. Methods: The sample included 170 patients who applied to Internal Diseases, Radiation Oncology, Thorax diseases clinics and Chemotherapy polyclinic in a university hospital in Turkey between March and August, 2005, who met the research criteria, and who volunteered to participate in the study. The sample represented 20 % of the target population. Data were collected through SF-36 Quality of Life Scale and Multidimensional Scale of Perceived Social Support. Results: The patients’ Global Quality of Life mean score was found 38.67 ± 13.64, and mean score for the Perceived Social Support was found 59.19 ± 17.5. Global Quality of Life score was higher in those who underwent an operation and who received ambulatory health care. Although Global Quality of Life was not influenced by the gender variable, male patients’ level of well-being was found to be higher. Perceived Social Support total score was found to be higher in those who knew about their disease. Family support was found to be higher in those who were married and who lived in town; it was found to be low in those who had low socio-economic level and who received inpatient treatment. Friend support was found to be high in those who knew about their disease. Conclusion: There was a linear relationship between Perceived Social Support and Quality of Life. It is recommended that more studies with wider groups of participants would shed more light to the issue of identifying quality of life, social support level and the relationships between them in cancer patients.
Supporting Sensemaking of Complex Objects with Visualizations: Visibility and Complementarity of Interactions

Full Text Available Making sense of complex objects is difficult, and typically requires the use of external representations to support cognitive demands while reasoning about the objects. Visualizations are one type of external representation that can be used to support sensemaking activities. In this paper, we investigate the role of two design strategies in making the interactive features of visualizations more supportive of users’ exploratory needs when trying to make sense of complex objects. These two strategies are visibility and complementarity of interactions. We employ a theoretical framework concerned with human–information interaction and complex cognitive activities to inform, contextualize, and interpret the effects of the design strategies. The two strategies are incorporated in the design of Polyvise, a visualization tool that supports making sense of complex four-dimensional geometric objects. A mixed-methods study was conducted to evaluate the design strategies and the overall usability of Polyvise. We report the findings of the study, discuss some implications for the design of visualization tools that support sensemaking of complex objects, and propose five design guidelines. We anticipate that our results are transferrable to other contexts, and that these two design strategies can be used broadly in visualization tools intended to support activities with complex objects and information spaces.

Over the past decade, there intense consideration of managing flows in the River Murray to provide environmental benefits. In 1990 the Murray-Darling Basin Ministerial Council adopted a water quality policy: To maintain and, where necessary, improve existing water quality in the rivers of the Murray-Darling Basin for all beneficial uses - agricultural, environmental, urban, industrial and recreational, and in 1994 a flow policy: To maintain and where necessary improve existing flow regimes in the waterways of the Murray-Darling Basin to protect and enhance the riverine environment. The Audit of Water Use followed in 1995, culminating in the decision of the Ministerial Council to implement an interim cap on new diversions for consumptive use (the "Cap") in a bid to halt declining river health. In March 1999 the Environmental Flows and Water Quality Objectives for the River Murray Project (the Project) was set up, primarily to establish be developed that aims to achieve a sustainable river environment and water quality, in accordance with community needs, and including an adaptive approach to management and operation of the River. It will lead to objectives for water quality and environmental flows that are feasible, appropriate, have the support of the scientific, management and stakeholder communities, and carry acceptable levels of risk. This paper describes four key aspects of the process being undertaken to determine the objectives, and design the flow options that will meet those objectives: establishment of an appropriate technical, advisory and administrative framework; establishing clear evidence for regulation impacts; undergoing assessment of environmental flow needs; and filling knowledge gaps. A review of the impacts of flow regulation on the health of the River Murray revealed evidence for decline, but the case for flow regulation as the main cause is circumstantial or uncertain. This is to be expected, because the decline of the River Murray results

The 105-K East (KE) Basin Ion Exchange Column (IXC) cells, lead caves, and the surrounding vault are to be removed as necessary components in implementing ''Hanford Federal Facility Agreement and Consert Order'' (Ecology et al. 2003) milestone M-034-32 (Complete Removal of the K East Basin Structure). The IXCs consist of six units located in the KE Basin, three in operating positions in cells and three stored in a lead cave. Methods to remove the IXCs from the KE Basin were evaluated in KBC-28343, ''Disposal of K East Basin Ion Exchange Column Evaluation''. The method selected for removal was grouting of the six IXCs into a single monolith for disposal at the Environmental Restoration Disposal Facility (ERDF). Grout will be added to the IXC cells, IXC lead caves containing spent IXCs, and in the spaces between to immobilize the contaminants, provide self-shielding, minimize void space, and provide a structurally stable waste form. The waste to be offered for disposal is the encapsulated monolith defined by the exterior surfaces of the vault and the lower surface of the underlying slab. This document presents a summary of the data quality objective (DQO) process establishing the decisions and data required to support decision-making activities for disposition of the IXC monolith. The DQO process is completed in accordance with the seven-step planning process described in EPA QA/G-4, ''Guidance for the Data Quality Objectives Process'', which is used to clarify and study objectives; define the appropriate type, quantity, and quality of data; and support defensible decision-making. The DQO process involves the following steps: (1) state the problem; (2) identify the decision; (3) identify the inputs to the decision; (4) define the boundaries of the study; (5) develop a decision rule (DR); (6) specify tolerable limits on decision errors; and (7) optimize the design for obtaining data

2014-01-01

Since usage of digital video is wide spread nowadays, quality considerations have become essential, and industry demand for video quality measurement is rising. This proposal provides a method of perceptual quality assessment in H.264 standard encoder using objective modeling. For this purpose, quality impairments are calculated and a model is developed to compute the perceptual video quality metric based on no reference method. Because of the shuttle difference between the original video and the encoded video the quality of the encoded picture gets degraded, this quality difference is introduced by the encoding process like Intra and Inter prediction. The proposed model takes into account of the artifacts introduced by these spatial and temporal activities in the hybrid block based coding methods and an objective modeling of these artifacts into subjective quality estimation is proposed. The proposed model calculates the objective quality metric using subjective impairments; blockiness, blur and jerkiness compared to the existing bitrate only calculation defined in the ITU G 1070 model. The accuracy of the proposed perceptual video quality metrics is compared against popular full reference objective methods as defined by VQEG.
Object-oriented design and programming in medical decision support.

The concept of object-oriented design and programming has recently received a great deal of attention from the software engineering community. This paper highlights the realisable benefits of using the object-oriented approach in the design and development of clinical decision support systems. These systems seek to build a computational model of some problem domain and therefore tend to be exploratory in nature. Conventional procedural design techniques do not support either the process of model building or rapid prototyping. The central concepts of the object-oriented paradigm are introduced, namely encapsulation, inheritance and polymorphism, and their use illustrated in a case study, taken from the domain of breast histopathology. In particular, the dual roles of inheritance in object-oriented programming are examined, i.e., inheritance as a conceptual modelling tool and inheritance as a code reuse mechanism. It is argued that the use of the former is not entirely intuitive and may be difficult to incorporate into the design process. However, inheritance as a means of optimising code reuse offers substantial technical benefits.

2004-01-01

In 1999, the Swedish Parliament adopted fifteen environmental quality objectives, defining the quality of Sweden's environment and of its natural and cultural resources that will insure sustainable growth. In 2001, the government proposed interim targets for each objective, specifying the direction and time scale of the proposed actions. These objectives give Sweden a unique opportunity to define, quantify and achieve an ecologically sustainable environment. One of the national objectives, A Safe Radiation Environment, targets both ionising and non-ionising radiation and states, human health and biological diversity must be protected against the harmful effects of radiation in the environment. The Swedish Radiation Protection Authority (SSI) has the responsibility for formulating and achieving the interim targets for this objective. The targets presently focus on controlling radioactive emissions, limiting exposures to ultraviolet radiation and defining the risks from exposure to electromagnetic fields. Part of SSI's responsibility for the environmental quality objective is to develop a system for monitoring and quantifying progress towards each interim target. Sweden's National Board of Housing, Building and Planning (NBHBP) is responsible for another of the national objectives, A Good Built- Environment. As part of this objective, a special interim target for the indoor environment was approved by Parliament in 2002, which includes a specification for human exposure to radon in indoor air. It states: radon concentrations should be lower than 200 Bq/m3 in schools and pre-schools by the year 2010, and below 200 Bq/m3 in homes by 2020. This substantially raises the level of ambition regarding reducing exposure to indoor radon. The aim of this paper is to briefly summarize the role of radiological protection in Sweden's environmental quality objectives. (Author) 3 refs
An object-oriented approach to site characterization decision support

International Nuclear Information System (INIS)

Johnson, R.

1995-01-01

Effective decision support for site characterization is key to determining the nature and extent of contamination and the associated human and environmental risks. Site characterization data, however, present particular problems to technical analysts and decision-makers. Such data are four dimensional, incorporating temporal and spatial components. Their sheer volume can be daunting -- sites with hundreds of monitoring wells and thousands of samples sent for laboratory analyses are not uncommon. Data are derived from a variety of sources including laboratory analyses, non-intrusive geophysical surveys, historical information, bore logs, in-field estimates of key physical parameters such as aquifer transmissivity, soil moisture content, depth-to-water table, etc. Ultimately, decisions have to be made based on data that are always incomplete, often confusing, inaccurate, or inappropriate, and occasionally wrong. In response to this challenge, two approaches to environmental decision support have arisen, Data Quality Objectives (DQOS) and the Observational Approach (OA). DQOs establish criteria for data collection by clearly defining the decisions that need to be made, the uncertainty that can be tolerated, and the type and amount of data that needs to be collected to satisfy the uncertainty requirements. In practice, DQOs are typically based on statistical measures. The OA accepts the fact that the process of characterizing and remediating contaminated sites is always uncertain. Decision-making with the OA is based on what is known about a site, with contingencies developed for potential future deviations from the original assumptions about contamination nature, extent, and risks posed
A METHOD FOR IMPROVEMENT OF OBJECTIVITY OF E-SERVICE QUALITY EVALUATION

Directory of Open Access Journals (Sweden)

Renata Mekovec

2007-12-01

Full Text Available Measurement and improvement of e-service quality is important for sustaining competitive advantage of an e-commerce web site. A number of e-service quality measures have recently been developed that predominantly rely on the subjective evaluation of diverse quality attributes. To increase the objectivity of e-service quality measurement a recently developed measure of e-service quality has been adapted in a way that replaces its Likert type scales for evaluation of specific attributes with check-lists that include specific observable elements for appraisal and a scoring procedure. The consistency of scoring with this adaptation of an e-service quality measure was investigated in comparison to the use of the standard measure with Likert type scales and by the use of untrained and trained evaluators. The results of the empirical evaluation indicate a greater inter-rater consistency when the adapted/objective measure is used for evaluation of the efficiency dimension of e-service quality.
Design objectives with non-zero prescribed support displacements

When non-zero prescribed support displacements are involved in addition to design independent loads for a continuum/structure, then the objectives of minimum compliance (total elastic energy) and of maximum strength lead to different designs. This is verified by the presented sensitivities. Designs...... minimization as well as that of direct strength maximization; we choose the objective of obtaining uniform energy density and show by examples that the obtained solutions are close to fulfilling also strength maximization, with the price of increased compliance. Optimal design examples are presented...

The seismic support design of piping systems of nuclear power plants requires many experienced engineers and plenty of man-hours, because the seismic design conditions are very severe, the bulk volume of the piping systems is hyge and the design procedures are very complicated. Therefore we have developed a piping seismic design expert system, which utilizes the piping design data base of a 3 dimensional CAD system and automatically determines the piping support locations and support styles. The data base of this system contains the maximum allowable seismic support span lengths for straight piping and the span length reduction factors for bends, branches, concentrated masses in the piping, and so forth. The system automatically produces the support design according to the design knowledge extracted and collected from expert design engineers, and using design information such as piping specifications which give diameters and thickness and piping geometric configurations. The automatic seismic support design provided by this expert system achieves in the reduction of design man-hours, improvement of design quality, verification of design result, optimization of support locations and prevention of input duplication. In the development of this system, we had to derive the design logic from expert design engineers and this could not be simply expressed descriptively. Also we had to make programs for different kinds of design knowledge. For these reasons we adopted the object oriented programming paradigm (Smalltalk-80) which is suitable for combining programs and carrying out the design work

Objective: To investigate the objective factors that affect the image quality of infant cranial CT using different mAs. Materials and Methods: Ninety infants were divided into three groups randomly. The maximum anteroposterior diameter (MAPD) of skull of each infant was measured. Three reference levels, cerebellar, basal ganglia and centrum semiovale levels were selected respectively. Only one level was studied in each group and scanned with 150, 100 and 80 mAs. The subjective quality grade and the objective noise of all images were recorded and analysed statistically. Results: The average MAPD of ninety patients was (148.0±17.4) mm. On the cerebellar level, the subjective quality grade was lower than the other two levels, which were 6.3%, 9.4% and 22.9% respectively when mAs were 150, 100 and 80 mAs. Both quality grade of image and objective noise were significantly correlated with MAPD. Conclusions: The inherent high noise of cerebellar level and MAPD were the objective factors that affect the image quality of low-dose cranial CT of infant. (authors)

Adler, J. G.

1999-01-01

This data quality objective (DQO) summary report has been developed to support demolition and disposal of the 116-D and 116-DR stacks in the 100-D Area of the Hanford Site. This project-specific summary was developed to meet the requirements in BHI-EE-01, Environmental Investigations Procedures, Procedure 1.2, ''Data Quality Objectives,'' using a simplified DQO process. The pathway for disposal of the 116-D and 116-DR stacks is the Environmental Restoration Disposal Facility (ERDF), which requires the development of a waste profile. A combination of process knowledge, history, and existing analogous data will be used to build a waste profile to dispose of the stack and plenum debris in the ERDF. Additional sample data are not necessary for waste designation. This report also addresses the Resources, Conservation, and Recovery Act of 1976 treatment, storage, and disposal closure requirements associated with the 116-DR stack

The increasing application of ontology reuse and automated knowledge acquisition tools in ontology engineering brings about a shift of development efforts from knowledge modeling towards quality assurance. Despite the high practical importance, there has been a substantial lack of support for ensuring semantic accuracy and conciseness. In this thesis, we make a significant step forward in ontology engineering by developing a support for two such essential quality assurance activities.
Projector-Based Augmented Reality for Quality Inspection of Scanned Objects

Kern, J.; Weinmann, M.; Wursthorn, S.

2017-09-01

After scanning or reconstructing the geometry of objects, we need to inspect the result of our work. Are there any parts missing? Is every detail covered in the desired quality? We typically do this by looking at the resulting point clouds or meshes of our objects on-screen. What, if we could see the information directly visualized on the object itself? Augmented reality is the generic term for bringing virtual information into our real environment. In our paper, we show how we can project any 3D information like thematic visualizations or specific monitoring information with reference to our object onto the object's surface itself, thus augmenting it with additional information. For small objects that could for instance be scanned in a laboratory, we propose a low-cost method involving a projector-camera system to solve this task. The user only needs a calibration board with coded fiducial markers to calibrate the system and to estimate the projector's pose later on for projecting textures with information onto the object's surface. Changes within the projected 3D information or of the projector's pose will be applied in real-time. Our results clearly reveal that such a simple setup will deliver a good quality of the augmented information.
Spent nuclear fuels project characterization data quality objectives strategy

Lawrence, L.A.; Thornton, T.A.; Redus, K.S.

1994-12-01

A strategy is presented for implementation of the Data Quality Objectives (DQO) process to the Spent Nuclear Fuels Project (SNFP) characterization activities. Westinghouse Hanford Company (WHC) and the Pacific Northwest Laboratory (PNL) are teaming in the characterization of the SNF on the Hanford Site and are committed to the DQO process outlined in this strategy. The SNFP characterization activities will collect and evaluate the required data to support project initiatives and decisions related to interim safe storage and the path forward for disposal. The DQO process is the basis for the activity specific SNF characterization requirements, termed the SNF Characterization DQO for that specific activity, which will be issued by the WHC or PNL organization responsible for the specific activity. The Characterization Plan prepared by PNL defines safety, remediation, and disposal issues. The ongoing Defense Nuclear Facility Safety Board (DNFSB) requirement and plans and the fuel storage and disposition options studies provide the need and direction for the activity specific DQO process. The hierarchy of characterization and DQO related documentation requirements is presented in this strategy. The management of the DQO process and the means of documenting the DQO process are described as well as the tailoring of the DQO process to the specific need of the SNFP characterization activities. This strategy will assure stakeholder and project management that the proper data was collected and evaluated to support programmatic decisions
DATA QUALITY OBJECTIVES SUMMARY REPORT FOR THE 105K EAST BASIN ION EXCHANGE COLUMN MONOLITH

Energy Technology Data Exchange (ETDEWEB)

JOCHEN, R.M.

2007-02-07

The 105-K East (KE) Basin Ion Exchange Column (IXC) cells, lead caves, and the surrounding vault are to be removed as necessary components in implementing ''Hanford Federal Facility Agreement and Consert Order'' (Ecology et al. 2003) milestone M-034-32 (Complete Removal of the K East Basin Structure). The IXCs consist of six units located in the KE Basin, three in operating positions in cells and three stored in a lead cave. Methods to remove the IXCs from the KE Basin were evaluated in KBC-28343, ''Disposal of K East Basin Ion Exchange Column Evaluation''. The method selected for removal was grouting of the six IXCs into a single monolith for disposal at the Environmental Restoration Disposal Facility (ERDF). Grout will be added to the IXC cells, IXC lead caves containing spent IXCs, and in the spaces between to immobilize the contaminants, provide self-shielding, minimize void space, and provide a structurally stable waste form. The waste to be offered for disposal is the encapsulated monolith defined by the exterior surfaces of the vault and the lower surface of the underlying slab. This document presents a summary of the data quality objective (DQO) process establishing the decisions and data required to support decision-making activities for disposition of the IXC monolith. The DQO process is completed in accordance with the seven-step planning process described in EPA QA/G-4, ''Guidance for the Data Quality Objectives Process'', which is used to clarify and study objectives; define the appropriate type, quantity, and quality of data; and support defensible decision-making. The DQO process involves the following steps: (1) state the problem; (2) identify the decision; (3) identify the inputs to the decision; (4) define the boundaries of the study; (5) develop a decision rule (DR); (6) specify tolerable limits on decision errors; and (7) optimize the design for obtaining data.

Full Text Available This paper assesses the Website of a chemical company, Deza, relative to strategy and Website quality. In an attempt to obtain both an objective and subjective measure of the quality of the Deza website, two assessment methods have been used. Firstly, a subjective assessment was conducted based on the WebQual survey instrument proposed by Barnes and Vidgen (2000. Secondly, a more objective assessment was conducted via an “informational content analysis”, based on the work of Carlson et. al. (2001. Analysis of the results of the WebQual survey suggest that overall, the Deza Website is perceived by the user as being of a higher quality than the Koppers Website, but a lower quality then the Nalon Website. The Information content analysis also ranks the Deza website as being superior to Koppers and inferior to Nalon.

The U.S. Department of Energy has developed a schedule and approach for the removal of spent fuels, sludge, and debris from the K East (KE) and K West (KW) Basins, located in the 100 Area at the Hanford Site. The project that is the subject of this data quality objective (DQO) process is focused on the removal of debris from the K Basins and onsite disposal of the debris at the Environmental Restoration Disposal Facility (ERDF). This material previously has been dispositioned at the Hanford Low-Level Burial Grounds (LLBGs) or Central Waste Complex (CWC). The goal of this DQO process and the resulting Sampling and Analysis Plan (SAP) is to provide the strategy for characterizing and designating the K-Basin debris to determine if it meets the Environmental Restoration Disposal Facility Waste Acceptance Criteria (WAC), Revision 3 (BHI 1998). A critical part of the DQO process is to agree on regulatory and WAC interpretation, to support preparation of the DQO workbook and SAP

Assessing quality of health services, for example through supportive supervision, is essential for strengthening healthcare delivery. Most systematic health facility assessment mechanisms, however, are not suitable for routine supervision. The objective of this study is to describe a quality assessment methodology using an electronic format that can be embedded in supervision activities and conducted by council health staff. An electronic Tool to Improve Quality of Healthcare (e-TIQH) was developed to assess the quality of primary healthcare provision. The e-TIQH contains six sub-tools, each covering one quality dimension: infrastructure and equipment of the facility, its management and administration, job expectations, clinical skills of the staff, staff motivation and client satisfaction. As part of supportive supervision, council health staff conduct quality assessments in all primary healthcare facilities in a given council, including observation of clinical consultations and exit interviews with clients. Using a hand-held device, assessors enter data and view results in real time through automated data analysis, permitting immediate feedback to health workers. Based on the results, quality gaps and potential measures to address them are jointly discussed and actions plans developed. For illustrative purposes, preliminary findings from e-TIQH application are presented from eight councils of Tanzania for the period 2011-2013, with a quality score quality dimensions at baseline. Clinical practice was unsatisfactory in six councils, with more mixed results for availability of infrastructure and equipment, and for administration and management. In contrast, client satisfaction scored surprisingly high. Over time, each council showed a significant overall increase of 3-7 % in mean score, with the most pronounced improvements in staff motivation and job expectations. Given its comprehensiveness, convenient handling and automated statistical reports, e-TIQH enables

This paper is part of a study of intelligent architectures for distributed control and communications systems. The study focuses on optimizing control systems by evaluating the performance of middleware through quality of service (QoS) parameters and the optimization of control using Quality of Control (QoC) parameters. The main aim of this work is to study, design, develop, and evaluate a distributed control architecture based on the Data-Distribution Service for Real-Time Systems (DDS) communication standard as proposed by the Object Management Group (OMG). As a result of the study, an architecture called Frame-Sensor-Adapter to Control (FSACtrl) has been developed. FSACtrl provides a model to implement an intelligent distributed Event-Based Control (EBC) system with support to measure QoS and QoC parameters. The novelty consists of using, simultaneously, the measured QoS and QoC parameters to make decisions about the control action with a new method called Event Based Quality Integral Cycle. To validate the architecture, the first five Braitenberg vehicles have been implemented using the FSACtrl architecture. The experimental outcomes, demonstrate the convenience of using jointly QoS and QoC parameters in distributed control systems.

The second study by the LMRG focuses on measuring confocal laser scanning microscope (CLSM) resolution, objective lens quality, spectral imaging accuracy and spectral un-mixing. Affordable test samples for each aspect of the study were designed, prepared and sent to 116 labs from 23 countries across the globe. Detailed protocols were designed for the three tests and customized for most of the major confocal instruments being used by the study participants. One protocol developed for measuring resolution and objective quality was recently published in Nature Protocols (Cole, R. W., T. Jinadasa, et al. (2011). Nature Protocols 6(12): 1929–1941). The first study involved 3D imaging of sub-resolution fluorescent microspheres to determine the microscope point spread function. Results of the resolution studies as well as point spread function quality (i.e. objective lens quality) from 140 different objective lenses will be presented. The second study of spectral accuracy looked at the reflection of the laser excitation lines into the spectral detection in order to determine the accuracy of these systems to report back the accurate laser emission wavelengths. Results will be presented from 42 different spectral confocal systems. Finally, samples with double orange beads (orange core and orange coating) were imaged spectrally and the imaging software was used to un-mix fluorescence signals from the two orange dyes. Results from 26 different confocal systems will be summarized. Time will be left to discuss possibilities for the next LMRG study.
Zebra Mussel Farming in the Szczecin (Oder Lagoon: Water-Quality Objectives and Cost-Effectiveness

Directory of Open Access Journals (Sweden)

Gerald Schernewski

2012-06-01

Full Text Available The Oder (Szczecin Lagoon in the southern Baltic Sea is a heavily eutrophicated and degraded coastal ecosystem. We applied a systems approach framework to critically evaluate whether existing water-management measures achieve water-quality objectives for the river and lagoon systems. Our simulations reveal that the existing water-quality objectives for the river and the coastal waters are not sufficiently complementary. We suggest new water-quality threshold concentrations, which are in agreement with the European Water Framework Directive, and we calculate acceptable maximum nutrient loads for the Oder River. These calculations suggest that external nutrient-load reductions in the river basin alone seem insufficient to achieve good water quality in the lagoon. A comprehensive eutrophication management approach should also include internal nutrient-retention and nutrient-removal measures in the lagoon. We focus on mussel farming, i.e., that of zebra mussels, Dreissena polymorpha, because they are efficient in removing nutrients and improving water transparency in the Oder Lagoon. For this purpose, the ecosystem model ERGOM is extended by a mussel module and an economic model. The economic model describes costs and benefits of mussel cultivation depending on the the farm size. We included additional potential sources of income such as water-quality tax or emission certificates. The simulations show that mussel farming in the lagoon is a suitable supportive measure and, at a load-reduction target of 50% or more, it is a cost-efficient measure for removing nutrients and for implementing the Baltic Sea Action Plan. In the Oder Lagoon, mussel farming could potentially remove nearly 1000 t of N (70 t of P/year, or about 2% of the present N and P loads, and it would have the additional benefit of improving water transparency.

Caregiver social support quality when interacting with cancer survivors: advancing the dual-process model of supportive communication.

Harvey-Knowles, Jacquelyn; Faw, Meara H

2018-04-01

Cancer caregivers often experience significant challenges in their motivation and ability to comfort cancer survivors, particularly in a spousal or romantic context. Spousal cancer caregivers have been known to report even greater levels of burden and distress than cancer sufferers, yet still take on the role of acting as an informal caregiver so they can attend to their partner's needs. The current study tested whether a theoretical model of supportive outcomes-the dual-process model of supportive communication-explained variations in cancer caregivers' motivation and ability to create high-quality support messages. The study also tested whether participant engagement with reflective journaling on supportive acts was associated with increased motivation or ability to generate high-quality support messages. Based upon the dual-process model, we posited that, following supportive journaling tasks, caregivers of spouses currently managing a cancer experience would report greater motivation but also greater difficulty in generating high-quality support messages, while individuals caring for a patient in remission would report lower motivation but greater ability to create high-quality support messages. Findings provided support for these assertions and suggested that reflective journaling tasks might be a useful tool for improving remission caregivers' ability to provide high-quality social support to survivors. Corresponding theoretical and applied implications are discussed.

Cardiac vagal control (CVC) has been linked to both physical and mental health. One critical aspect of health, that has not received much attention, is sleep. We hypothesized that adults with higher CVC--operationalized by high-frequency heart rate variability (HF-HRV)--will exhibit better sleep quality assessed both subjectively (i.e., with Pittsburgh Sleep Quality Index) and objectively (i.e., with polysomnography). HF-HRV was measured in 29 healthy young women during an extended neutral film clip. Participants then underwent full polysomnography to obtain objective measures of sleep quality and HF-HRV during a night of sleep. As expected, higher resting HF-HRV was associated with higher subjective and objective sleep quality (i.e., shorter sleep latency and fewer arousals). HF-HRV during sleep (overall or separated by sleep phases) showed less consistent relationships with sleep quality. These findings indicate that high waking CVC may be a key predictor of healthy sleep. Copyright © 2015 The Authors. Published by Elsevier B.V. All rights reserved.

Quality control of X-ray facilities in radiological departments of large hospitals is possible only if the instrumentation used for measurements is interfaced to a computer. The central computer helps to organize the measurements as well as analyse and record the results. It can also be connected to a densitometer and camera for evaluating radiographs of test devices. Other quality control tests are supported by a mobile station with equipment for non-invasive dosimetry measurements. Experience with a computer-supported system in quality control of film and film processing is described and the evaluation methods of ANSI and the German industrial standard DIN are compared. The disadvantage of these methods is the exclusion of film quality parameters, which can make processing control almost worthless. (author)

Full Text Available Background. The proposed National Health Insurance policy for South Africa (SA requires hospitals to maintain high-quality International Statistical Classification of Diseases (ICD codes for patient records. While considerable strides had been made to improve ICD coding coverage by digitising the discharge process in the Western Cape Province, further intervention was required to improve data quality. The aim of this controlled before-and-after study was to evaluate the impact of a clinician training and support initiative to improve ICD coding quality. Objective. To compare ICD coding quality between two central hospitals in the Western Cape before and after the implementation of a training and support initiative for clinicians at one of the sites. Methods. The difference in differences in data quality between the intervention site and the control site was calculated. Multiple logistic regression was also used to determine the odds of data quality improvement after the intervention and to adjust for potential differences between the groups. Results. The intervention had a positive impact of 38.0% on ICD coding completeness over and above changes that occurred at the control site. Relative to the baseline, patient records at the intervention site had a 6.6 (95% confidence interval 3.5 - 16.2 adjusted odds ratio of having a complete set of ICD codes for an admission episode after the introduction of the training and support package. The findings on impact on ICD coding accuracy were not significant. Conclusion. There is sufficient pragmatic evidence that a training and support package will have a considerable positive impact on ICD coding completeness in the SA setting.
Virtual memory support for distributed computing environments using a shared data object model

Conventional storage management systems provide one interface for accessing memory segments and another for accessing secondary storage objects. This hinders application programming and affects overall system performance due to mandatory data copying and user/kernel boundary crossings, which in the microkernel case may involve context switches. Memory-mapping techniques may be used to provide programmers with a unified view of the storage system. This paper extends such techniques to support a shared data object model for distributed computing environments in which good support for coherence and synchronization is essential. The approach is based on a microkernel, typed memory objects, and integrated coherence control. A microkernel architecture is used to support multiple coherence protocols and the addition of new protocols. Memory objects are typed and applications can choose the most suitable protocols for different types of object to avoid protocol mismatch. Low-level coherence control is integrated with high-level concurrency control so that the number of messages required to maintain memory coherence is reduced and system-wide synchronization is realized without severely impacting the system performance. These features together contribute a novel approach to the support for flexible coherence under application control.

Contemporary object-oriented programming seeks to enable distributed computing by accessing remote objects using blocking remote procedure calls. This technique, however, suffers from several drawbacks because it relies on the assumption of stable network connections and synchronous method...... invocations. In this paper we present an approach to support distributed programming, which rely on local object replicas keeping themselves synchronized using an underlying peer-to-peer infrastructure. We have termed our approach Peer-to-peer Distributed Shared Objects (PDSO). This PDSO approach has been...

Full Text Available Objectives To examine maternal functioning and wellbeing as important aspects of a family’s adaptation to chronic paediatric conditions, in particular, children with diabetes. Method This cross-sectional study investigated the difference between the perceived quality of life of mothers of children with diabetes (n = 63 and mothers of children without diabetes (n = 114. The study also examined the role of self-efficacy, relationship satisfaction, number of social support providers, and satisfaction with social support in predicting quality of life. Results Mothers who had a child with diabetes had lower quality of life measured by general health, vitality, social functioning, role-emotional, and mental health than mothers that did not have a child with diabetes. Self-efficacy, relationship satisfaction, and social support were significant predictors of quality of life (mental health domain. Conclusion In order to enhance their psychological wellbeing, mothers of children with diabetes require adequate psychosocial support. Other implications for research and potential interventions are discussed.

Full Text Available Background: There is controversy surrounding the impact of workplace interventions aimed at improving social support and supervisory quality on absenteeism, productivity and financial outcomes. Objective: To determine the value of social support interventions for work outcomes. Methods: Databases were searched for systematic reviews between 2000 and 2012 to complete a synthesis of systematic reviews guided by the PRISMA statement and the IOM guidelines for systematic reviews. Assessment of articles for inclusion and methodological quality was conducted independently by at least two researchers, with differences resolved by consensus. Results: The search resulted in 3363 titles of which 3248 were excluded following title/abstract review, leaving 115 articles that were retrieved and underwent full article review. 10 articles met the set inclusion criteria, with 7 focusing on social support, 2 on supervisory quality and 1 on both. We found moderate and limited evidence, respectively, that social support and supervisory quality interventions positively impact workplace outcomes. Conclusion: There is moderate evidence that social support and limited evidence that supervisory quality interventions have a positive effect on work outcomes.

Do the strategies women use to disclose information about their infertility to social network members impact the quality of the support they receive and their quality of life? The data showed that women who disclosed infertility-related information in direct ways, rather than in indirect ways (e.g. by incremental disclosures or through third parties), to social network members perceived higher quality support and reported greater quality of life related to their infertility experience. Social support has been shown to buffer stress associated with various health issues including infertility. The way people disclose information about stressors has been associated with the quality of the support they receive. Disclosing information in a way that most effectively elicits support is beneficial because women with infertility who have lower levels of stress are more likely to seek and remain in treatment. This cross-sectional study of 301 infertile women was conducted in the USA. To determine the variation in length of infertility and treatment decisions, we conducted an online survey of 301 American women coping with infertility. We investigated the strategies women used to disclose infertility-related information with social network members, their perceptions of support from friends and family, and their quality of life both in general (overall quality of life) and related to the experience of infertility (fertility quality of life). Direct disclosure of experiences related to infertility was positively and significantly associated with the perceived quality of social support received (P women's fertility quality of life (95% CI: 0.18, 1.05) and overall quality of life (95% CI: 0.10, 0.30). This effect is particularly noteworthy for the model predicting fertility quality of life, which exhibited a non-significant main effect with direct disclosures. The non-significant main effect combined with the significant indirect effect suggests that perceived support quality

Background Uganda adopted voluntary medical male circumcision (VMMC) (also called Safe Male Circumcision in Uganda), as part of its HIV prevention strategy in 2010. Since then, the Ministry of Health (MOH) has implemented VMMC mostly with support from the United States President’s Emergency Plan for AIDS Relief (PEPFAR) through its partners. In 2012, two PEPFAR-led external quality assessments evaluated compliance of service delivery sites with minimum quality standards. Quality gaps were identified, including lack of standardized forms or registers, lack of documentation of client consent, poor preparedness for emergencies and use of untrained service providers. In response, PEPFAR, through a USAID-supported technical assistance project, provided support in quality improvement to the MOH and implementing partners to improve quality and safety in VMMC services and build capacity of MOH staff to continuously improve VMMC service quality. Methods and Findings Sites were supported to identify barriers in achieving national standards, identify possible solutions to overcome the barriers and carry out improvement plans to test these changes, while collecting performance data to objectively measure whether they had bridged gaps. A 53-indicator quality assessment tool was used by teams as a management tool to measure progress; teams also measured client-level indicators through self-assessment of client records. At baseline (February-March 2013), less than 20 percent of sites scored in the “good” range (>80%) for supplies and equipment, patient counseling and surgical procedure; by November 2013, the proportion of sites scoring “good” rose to 67 percent, 93 percent and 90 percent, respectively. Significant improvement was noted in post-operative follow-up at 48 hours, sexually transmitted infection assessment, informed consent and use of local anesthesia but not rate of adverse events. Conclusion Public sector providers can be engaged to address the quality of

Manipulation of Unknown Objects to Improve the Grasp Quality Using Tactile Information.

Science.gov (United States)

Montaño, Andrés; Suárez, Raúl

2018-05-03

This work presents a novel and simple approach in the area of manipulation of unknown objects considering both geometric and mechanical constraints of the robotic hand. Starting with an initial blind grasp, our method improves the grasp quality through manipulation considering the three common goals of the manipulation process: improving the hand configuration, the grasp quality and the object positioning, and, at the same time, prevents the object from falling. Tactile feedback is used to obtain local information of the contacts between the fingertips and the object, and no additional exteroceptive feedback sources are considered in the approach. The main novelty of this work lies in the fact that the grasp optimization is performed on-line as a reactive procedure using the tactile and kinematic information obtained during the manipulation. Experimental results are shown to illustrate the efficiency of the approach.

1994-08-01

This publication provides the guiding principles and objectives for the operation and support of standard nuclear plants. They are the basis for designing the processes to operate and support the new plants and to estimate the staffing options. INPO has facilitated and coordinated the development of these principles and objectives under the industry's Strategic Plan for Building New Nuclear Power Plants. The industry's plan, first published in 1990, designates INPO as the lead in achieving the following goals: 1. Establish an institutional framework and approach to implement and maintain a model for life-cycle standardization of a family of plants. 2. Develop standardization objectives and selected standardized function and process descriptions to provide a basis for uniformity in appropriate aspects of the organizational structure; administrative controls; and construction, startup, operating, and maintenance practices. 3. Develop an approach to maintain the standard design and design intent as well as standardized operational approaches in all units within a family of plants over their lifetimes. This document supports these goals. Twelve guiding principles are followed by descriptions of four functions, and after that eight processes with their associated objectives

Flávia Batista Portugal

Full Text Available The objective of this study was to identify the association between emotional distress and social support networks with quality of life in primary care patients. This was a cross-sectional study involving 1,466 patients in the cities of São Paulo and Rio de Janeiro, Brazil, in 2009/2010. The General Health Questionnaire, the Hospital Anxiety and Depression Scale and the brief version of the World Health Organization Quality of Life Instrument were used. The Social Support Network Index classified patients with the highest and lowest index as socially integrated or isolated. A bivariate analysis and four multiple linear regressions were conducted for each quality of life outcome. The means scores for the physical, psychological, social relations, and environment domains were, respectively, 64.7; 64.2; 68.5 and 49.1. In the multivariate analysis, the psychological domain was negatively associated with isolation, whereas the social relations and environment domains were positively associated with integration. Integration and isolation proved to be important factors for those in emotional distress as they minimize or maximize negative effects on quality of life.

Real-time tele-echocardiography is widely used to remotely diagnose or exclude congenital heart defects. Cost effective technical implementation is realised using low-bandwidth transmission systems and lossy compression (videoconferencing) schemes. In our study, DICOM video sequences were converted to common multimedia formats, which were then, compressed using three lossy compression algorithms. We then applied a digital (multimedia) video quality metric (VQM) to determine objectively a value for degradation due to compression. Three levels of compression were simulated by varying system bandwidth and compared to a subjective assessment of video clip quality by three paediatric cardiologists with more than 5 years of experience.

The 221-U Canyon Disposition Alternatives Data Quality Objective (DQO) Process identifies the sampling and analytical requirements necessary to support future detailed evaluation of alternatives via the CERCLA process, for final disposition of the 221-U Canyon Facility. Viable alternatives for the disposition of the 221-U Facility have been identified in a CERCLA Phase I Feasibility Study (FS) (DOE-RL 1997) for the Canyon Disposition Initiative (CDI). The scope of this DQO Process is limited to the 221-U Process Canyon Building and equipment contained within the facility. Associated stacks, filters, solvent handling, vaults, and storage facilities external to the 221-U Building are not addressed in this DQO. This DQO focuses on the 221-U Building because it provides the greatest potential source of contaminant volumes and concentrations and the physical structure poses the greatest challenge for disposition decisions

Kurek, Wojciech; Ostfeld, Avi

2013-01-30

A multi-objective methodology utilizing the Strength Pareto Evolutionary Algorithm (SPEA2) linked to EPANET for trading-off pumping costs, water quality, and tanks sizing of water distribution systems is developed and demonstrated. The model integrates variable speed pumps for modeling the pumps operation, two water quality objectives (one based on chlorine disinfectant concentrations and one on water age), and tanks sizing cost which are assumed to vary with location and diameter. The water distribution system is subject to extended period simulations, variable energy tariffs, Kirchhoff's laws 1 and 2 for continuity of flow and pressure, tanks water level closure constraints, and storage-reliability requirements. EPANET Example 3 is employed for demonstrating the methodology on two multi-objective models, which differ in the imposed water quality objective (i.e., either with disinfectant or water age considerations). Three-fold Pareto optimal fronts are presented. Sensitivity analysis on the storage-reliability constraint, its influence on pumping cost, water quality, and tank sizing are explored. The contribution of this study is in tailoring design (tank sizing), pumps operational costs, water quality of two types, and reliability through residual storage requirements, in a single multi-objective framework. The model was found to be stable in generating multi-objective three-fold Pareto fronts, while producing explainable engineering outcomes. The model can be used as a decision tool for both pumps operation, water quality, required storage for reliability considerations, and tank sizing decision-making. Copyright © 2012 Elsevier Ltd.

Full Text Available Large efforts are on-going within the EU to prepare the Marine Strategy Framework Directive’s (MSFD assessment of the environmental status of the European seas. This assessment will only be as good as the indicators chosen to monitor the eleven descriptors of good environmental status (GEnS. An objective and transparent framework to determine whether chosen indicators actually support the aims of this policy is, however, not yet in place. Such frameworks are needed to ensure that the limited resources available to this assessment optimize the likelihood of achieving GEnS within collaborating states. Here, we developed a hypothesis-based protocol to evaluate whether candidate indicators meet quality criteria explicit to the MSFD, which the assessment community aspires to. Eight quality criteria are distilled from existing initiatives, and a testing and scoring protocol for each of them is presented. We exemplify its application in three worked examples, covering indicators for three GEnS descriptors (1, 5 and 6, various habitat components (seaweeds, seagrasses, benthic macrofauna and plankton, and assessment regions (Danish, Lithuanian and UK waters. We argue that this framework provides a necessary, transparent and standardized structure to support the comparison of candidate indicators, and the decision-making process leading to indicator selection. Its application could help identify potential limitations in currently available candidate metrics and, in such cases, help focus the development of more adequate indicators. Use of such standardized approaches will facilitate the sharing of knowledge gained across the MSFD parties despite context-specificity across assessment regions, and support the evidence-based management of European seas.

This presentation will report on three projects that used interactive workshops with stakeholders to develop problem formulations for Multi-Objective Evolutionary Algorithm (MOEA)-based decision support in diverse fields - water resources planning, water quality engineering under climate extremes, and sustainable materials design. When combined with a simulation model of a system, MOEAs use intelligent search techniques to provide new plans or designs. This approach is gaining increasing prominence in design and planning for environmental sustainability. To use this technique, a problem formulation - objectives and constraints (quantitative measures of performance) and decision variables (actions that can be modified to improve the system) - must be identified. Although critically important for MOEA effectiveness, the problem formulations are not always developed with stakeholders' interests in mind. To ameliorate this issue, project workshops were organized to improve the tool's relevance as well as collaboratively build problem formulations that can be used in applications. There were interesting differences among the projects, which altered the findings of each workshop. Attendees ranged from a group of water managers on the Front Range of Colorado, to water utility representatives from across the country, to a set of designers, academics, and trade groups. The extent to which the workshop participants were already familiar with simulation tools contributed to their willingness to accept the solutions that were generated using the tool. Moreover, in some instances, brainstorming new objectives to include within the MOEA expanded the scope of the problem formulation, relative to the initial conception of the researchers. Through describing results across a diversity of projects, the goal of this presentation is to report on how our approach may inform future decision support collaboration with a variety of stakeholders and sectors.

Gas samples from drums of radioactive waste at the Department of Energy (DOE) Idaho National Engineering Laboratory are being characterized for 29 volatile organic compounds to determine the feasibility of storing the waste in DOE's Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico. Quality requirements for the gas chromatography (GC) and GC/mass spectrometry chemical methods used to analyze the waste are specified in the Quality Assurance Program Plan for the WIPP Experimental Waste Characterization Program. Quality requirements consist of both objective criteria (data quality objectives, DQOs) and statistical criteria (process control). The DQOs apply to routine sample analyses, while the statistical criteria serve to determine and monitor precision and accuracy (P ampersand A) of the analysis methods and are also used to assign upper confidence limits to measurement results close to action levels. After over two years and more than 1000 sample analyses there are two general conclusions concerning the two approaches to quality control: (1) Objective criteria (e.g., ± 25% precision, ± 30% accuracy) based on customer needs and the usually prescribed criteria for similar EPA- approved methods are consistently attained during routine analyses. (2) Statistical criteria based on short term method performance are almost an order of magnitude more stringent than objective criteria and are difficult to satisfy following the same routine laboratory procedures which satisfy the objective criteria. A more cost effective and representative approach to establishing statistical method performances criteria would be either to utilize a moving average of P ampersand A from control samples over a several month time period or to determine within a sample variation by one-way analysis of variance of several months replicate sample analysis results or both. Confidence intervals for results near action levels could also be determined by replicate analysis of the sample in

Purpose: Iterative reconstruction (IR) algorithms have the potential to reduce radiation dose in CT diagnostic imaging. As these algorithms become available on the market, a standardizable method of quantifying the dose reduction that a particular IR method can achieve would be valuable. Such a method would assist manufacturers in making promotional claims about dose reduction, buyers in comparing different devices, physicists in independently validating the claims, and the United States Food and Drug Administration in regulating the labeling of CT devices. However, the nonlinear nature of commercially available IR algorithms poses challenges to objectively assessing image quality, a necessary step in establishing the amount of dose reduction that a given IR algorithm can achieve without compromising that image quality. This review paper seeks to consolidate information relevant to objectively assessing the quality of CT IR images, and thereby measuring the level of dose reduction that a given IR algorithm can achieve. Methods: The authors discuss task-based methods for assessing the quality of CT IR images and evaluating dose reduction. Results: The authors explain and review recent literature on signal detection and localization tasks in CT IR image quality assessment, the design of an appropriate phantom for these tasks, possible choices of observers (including human and model observers), and methods of evaluating observer performance. Conclusions: Standardizing the measurement of dose reduction is a problem of broad interest to the CT community and to public health. A necessary step in the process is the objective assessment of CT image quality, for which various task-based methods may be suitable. This paper attempts to consolidate recent literature that is relevant to the development and implementation of task-based methods for the assessment of CT IR image quality.

Such a method would assist manufacturers in making promotional claims about dose reduction, buyers in comparing different devices, physicists in independently validating the claims, and the United States Food and Drug Administration in regulating the labeling of CT devices. However, the nonlinear nature of commercially available IR algorithms poses challenges to objectively assessing image quality, a necessary step in establishing the amount of dose reduction that a given IR algorithm can achieve without compromising that image quality. This review paper seeks to consolidate information relevant to objectively assessing the quality of CT IR images, and thereby measuring the level of dose reduction that a given IR algorithm can achieve. Methods: The authors discuss task-based methods for assessing the quality of CT IR images and evaluating dose reduction. Results: The authors explain and review recent literature on signal detection and localization tasks in CT IR image quality assessment, the design of an appropriate phantom for these tasks, possible choices of observers (including human and model observers), and methods of evaluating observer performance. Conclusions: Standardizing the measurement of dose reduction is a problem of broad interest to the CT community and to public health. A necessary step in the process is the objective assessment of CT image quality, for which various task-based methods may be suitable. This paper attempts to consolidate recent literature that is relevant to the development and implementation of task-based methods for the assessment of CT IR image quality

to evaluate the impact of social support on postnatal depression and health-related quality of life. prospective cohort study. Data were collected at baseline and at six weeks post discharge using a postal survey. between August and December 2008, 320 women from a large tertiary hospital were recruited following the birth of their infant. Edinburgh Postnatal Depression Scale (EPDS), Maternity Social Support Scale and World Health Organization Quality of Life assessment questionnaire. of the 320 women recruited, 222 (69.4%) returned their six-week questionnaire. Women with low social support had significantly higher scores on the EPDS than women who reported adequate support (p = 0.007). There was also a significant effect of social support on health-related quality of life. Women with low family or partner support scored lower in all domains, with the greatest mean difference in the social health domain (p = 0.000). Of those scoring >10 on the EPDS, 75.5% had sought professional help. women with low social support are more likely to report postnatal depression and lower quality of life than well-supported women. Careful assessment of a woman's level of support following the birth, particularly from her partner and family, may provide useful information for possible interventions.

To meet the current standards of excellence necessary for blood establishments, we have learned from industry that a movement toward organization-wide quality assurance/total quality management must be made. Everyone in the organization must accept responsibility for participating in providing the highest quality products and services. Quality must be built into processes and design systems to support these quality processes. Quality assurance has been redefined to include a quality planning function described as the most effective way of designing quality into processes. A formalized quality planning process must be part of quality assurance. Continuous quality improvement has been identified as the strategy every blood establishment must support while striving for error-free processing as the long-term objective. The auditing process has been realigned to support and facilitate this same objective. Implementing organization-wide quality assurance/total quality management is one proven plan for guaranteeing the quality of the 20 million products that are transfused into 4 million patients each year and for moving toward the new order.

An individual or organization that sets out to implement an innovation (e.g., a new technology, program, or policy) generally requires support. In the Interactive Systems Framework for Dissemination and Implementation, a Support System should work with Delivery Systems (national, state and/or local entities such as health and human service organizations, community-based organizations, schools) to enhance their capacity for quality implementation of innovations. The literature on the Support System [corrected] has been underresearched and under-developedThis article begins to conceptualize theory, research, and action for an evidence-based system for innovation support (EBSIS). EBSIS describes key priorities for strengthening the science and practice of support. The major goal of EBSIS is to enhance the research and practice of support in order to build capacity in the Delivery System for implementing innovations with quality, and thereby, help the Delivery System achieve outcomes. EBSIS is guided by a logic model that includes four key support components: tools, training, technical assistance, and quality assurance/quality improvement. EBSIS uses the Getting To Outcomes approach to accountability to aid the identification and synthesis of concepts, tools, and evidence for support. We conclude with some discussion of the current status of EBSIS and possible next steps, including the development of collaborative researcher-practitioner-funder-consumer partnerships to accelerate accumulation of knowledge on the Support System.

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

Breast cancer patients commonly use the internet as an information resource. Our objective was to evaluate the quality of online information available to support patients facing a decision for breast surgery. Breast cancer surgery-related queries were performed (Google and Bing), and reviewed for content pertinent to breast cancer surgery. The DISCERN instrument was used to evaluate websites' structural components that influence publication reliability and ability of information to support treatment decision-making. Scores of 4/5 were considered "good." 45 unique websites were identified. Websites satisfied a median 5/9 content questions. Commonly omitted topics included: having a choice between breast conservation and mastectomy (67%) and potential for 2nd surgery to obtain negative margins after breast conservation (60%). Websites had a median DISCERN score of 2.9 (range 2.0-4.5). Websites achieved higher scores on structural criteria (median 3.6 [2.1-4.7]), with 24% rated as "good." Scores on supporting decision-making questions were lower (2.6 [1.3-4.4]), with only 7% scoring "good." Although numerous breast cancer-related websites exist, most do a poor job providing women with essential information necessary to actively participate in decision-making for breast cancer surgery. Providing easily- accessible, high-quality online information has the potential to significantly improve patients' experiences with decision-making. © 2015 Wiley Periodicals, Inc.

The main objective of the present work was the removal of aluminum from wines produced by gamma-alumina-supported yeast cells. Reagents such as Na2CO3, NH4OH, albumin, and Ca(OH)2 were used. Calcium in the presence of albumin was effective, whereas other reagents were not so effective. Because of the improved aroma and taste of distillates produced by gamma-alumina-supported biocatalyst, volatile byproducts of distillates were analyzed. They were also assessed by sensory tests. Methanol, acetaldehyde, ethyl acetate, propanol-1, isobutyl alcohol, and amyl alcohols were determined in distillates. It was noted that the amounts of higher alcohols and amyl alcohols decreased as the temperature of fermentation dropped, leading to a product of improved quality and reduced toxicity.
Development of test objects for image quality evaluation of digital mammography

International Nuclear Information System (INIS)

Pinto, Vitor Nascimento de Carvalho

2013-01-01

Mammography is the image exam called 'gold standard' for early detection of breast cancer. 111 Brazil, more than eight million mammograms are carried out per year. With the advancement of technology, the digital systems CR and DR for this diagnostic modality have been increasingly implemented, replacing the conventional screen-film system, which brought environmental problems, like the disposal of chemical waste, and is also responsible for the rejection of radiographic films with processing artifacts. Digital systems, besides not experiencing the problem of environmental pollution, are still capable of image processing, allowing a much lower rejection rate when compared to the conventional system. Moreover, the determination of an accurate diagnosis is highly dependent on the image quality of the examination. To ensure the reliability of the images produced by these systems, it is necessary to evaluate them on a regular basis. Unfortunately, there is no regulation in Brazil about the Quality Assurance of these systems. The aim of this study was to develop a set of test objects that allow the evaluation of some parameters of image quality of these systems, such as field image uniformity, the linearity between the air Kerma incident on detector and the mean pixel value (MPV) of the image, the spatial resolution of the system through the modulation transfer function (MTF) and also to suggest an object to be applied in the evaluation of contrast-to-noise ratio (CNR) and signal-difference-to-noise ratio (SDNR). In order to test the objects. 10 mammography centers were evaluated, seven with CR systems and three with the DR systems. To evaluate the linearity, besides the test objects high sensitivity dosimeters were necessary to be used, namely LiF:Mg,Cu,P TL dosimeters. The use of these dosimeters was recommended in order to minimize the time required to perform the tests and to decrease the number of exposures needed.

The ultimate goal is to obtain a modification of formal assessments that more closely corresponds to the subjective expert estimates (MOS.In considering the formal reference objective methods for image quality assessment we used the results of other authors, which offer results and comparative analyzes of the most effective algorithms. Based on these investigations we have chosen two of the most successful algorithm for which was made a further analysis in the MATLAB 7.8 R 2009 a (PQS and MSSSIM. The publication focuses on the features of the algorithms, which have great importance in practical implementation, but are insufficiently covered in the publications by other authors.In the implemented modification of the algorithm PQS boundary detector Kirsch was replaced by the boundary detector Canny. Further experiments were carried out according to the method of the ITU-R VT.500-13 (01/2012 using monochrome images treated with different types of filters (should be emphasized that an objective assessment of image quality PQS is applicable only to monochrome images. Images were obtained with a thermal imaging surveillance system. The experimental results proved the effectiveness of this modification.In the specialized literature in the field of formal to evaluation methods pictures, this type of modification was not mentioned.The method described in the publication can be applied to various practical implementations of digital image processing.Advisability and effectiveness of using the modified method of PQS to assess the structural differences between the images are shown in the article and this will be used in solving the problems of identification and automatic control.
Working memory contributes to the encoding of object location associations: Support for a 3-part model of object location memory.

Science.gov (United States)

Gillis, M Meredith; Garcia, Sarah; Hampstead, Benjamin M

2016-09-15

A recent model by Postma and colleagues posits that the encoding of object location associations (OLAs) requires the coordination of several cognitive processes mediated by ventral (object perception) and dorsal (spatial perception) visual pathways as well as the hippocampus (feature binding) [1]. Within this model, frontoparietal network recruitment is believed to contribute to both the spatial processing and working memory task demands. The current study used functional magnetic resonance imaging (fMRI) to test each step of this model in 15 participants who encoded OLAs and performed standard n-back tasks. As expected, object processing resulted in activation of the ventral visual stream. Object in location processing resulted in activation of both the ventral and dorsal visual streams as well as a lateral frontoparietal network. This condition was also the only one to result in medial temporal lobe activation, supporting its role in associative learning. A conjunction analysis revealed areas of shared activation between the working memory and object in location phase within the lateral frontoparietal network, anterior insula, and basal ganglia; consistent with prior working memory literature. Overall, findings support Postma and colleague's model and provide clear evidence for the role of working memory during OLA encoding. Published by Elsevier B.V.

Full Text Available Life quality of diabetic patients is always affected by psychosocial problems, physical disorders, and life style changes. It seems that the perceived social support could intervene in improving the life quality of these patients. The present study was carried out aiming to examine the relation between family social support and life quality of female patients with diabetes. This was a cross-sectional study. The statistical population included 173 diabetic females who were randomly selected from patients referred to Kermanshah diabetes research center. Data were collected using life quality questionnaire (Short Form-36 as well as perceived social support scale. The data analysis indicated that there is a significant correlation between family support and life quality of patients. Furthermore, concerning the components of life quality, there is a significant correlation between family social support and physical performance, physical limitation, tiredness, emotional health, social performance, pain, and general health of patients. However, no significant relation was found between family support and limitation of patients. Results showed that there is a direct relation between family support and the life quality in females with diabetes. Hence, it can be concluded that giving the family support to the female diabetic patients can increase their quality of life.

Full Text Available Summary. Raising of problem. Natural calamities, technogenic catastrophes and failures, result in destruction of building objects. Under the obstructions of destructions there can be victims. The most widespread technogenic failure are explosions of domestic gas. The structure of obstructions changes depending on parameters and direction of explosion, first of all size and location of wreckages. Sorting out of obstructions is executed by machines and mechanisms which do not answer the requirements of these works, that predetermines falling short of logistical support to the requirements of rescue or restoration works, and it increases terms and labour intensiveness of their conduct. Development of technological decisions is therefore needed for the effective sorting out of destructions of building objects. Purpose. Development of methodology of determination of logistical support of processes of sorting out of destructions of building and building. Conclusion. Experience of works shows on sorting out of the destroyed building objects, that they are executed with the use of imperfect logistical support, which are not taken into account by character of destruction of objects and is based on the use of buildings machines which do not answer the requirements of these processes, that results in considerable resource losses. Building machines with a multipurpose equipment, which provide the increase of efficiency of implementation of rescue and restoration works, are worked out. Methodology of determination of number of technique is worked out for providing of material-supply of sorting out of destructions, in particular on the initial stage of rescue works for liberation of victims from under obstructions.
Quality Assistance Objectives for Nondestructive Assay at the Waste Receiving and Processing (WRAP) Facility

2000-01-01

The Waste Receiving and Processing (WRAP) facility, located on the Word Site in southeast Washington, is a key link in the certification of transuranic (TRU) waste for shipment to the Waste Isolation Pilot Plant (WIPP). Waste characterization is one of the vital functions performed at WRAP, and nondestructive assay (NDA) measurements of TRU waste containers is one of two required methods used for waste characterization. The Waste Acceptance Criteria for the Waste Isolation Pilot Plant, DOE/WIPP-069 (WIPP-WAC) delineates the quality assurance objectives which have been established for NDA measurement systems. Sites must demonstrate that the quality assurance objectives can be achieved for each radioassay system over the applicable ranges of measurement. This report summarizes the validation of the WRAP NDA systems against the radioassay quality assurance objectives or QAOs. A brief description of the each test and significant conclusions are included. Variables that may have affected test outcomes and system response are also addressed

The psychosocial pathways underlying associations between benefit finding and quality of life are poorly understood. Here, we examined associations between benefit finding, social support, optimism and quality of life in a sample of 84 caregivers. Results revealed that quality of life was predicted by benefit finding, optimism and social support. Moreover, the association between benefit finding and quality of life was explained by social support, but not optimism; caregivers who reported greater benefit finding perceived their social support be higher and this, in turn, had a positive effect on their overall quality of life. These results underscore the importance of harnessing benefit finding to enhance caregiver quality of life. © The Author(s) 2014.

The Hanford Tank Waste Treatment and Immobilization Plant (WTP) is under construction for the U.S. Department of Energy by Bechtel National, Inc. and subcontractor URS Corporation (contract no. DE-AC27-01RV14136). The plant when completed will be the world's largest nuclear waste treatment facility. Bechtel and URS are tasked with designing, constructing, commissioning, and transitioning the plant to the long term operating contractor to process the legacy wastes that are stored in underground tanks (from nuclear weapons production between the 1940's and the 1980's). Approximately 56 million gallons of radioactive waste is currently stored in these tanks at the Hanford Site in southeastern Washington. There are three major WTP facilities being constructed for processing the tank waste feed. The Pretreatment (PT) facility receives feed where it is separated into a low activity waste (LAW) fraction and a high level waste (HLW) fraction. These fractions are transferred to the appropriate (HLW or LAW) facility, combined with glass former material, and sent to high temperature melters for formation of the glass product. In addition to PT, HLW and LAW, other facilities in WTP include the Laboratory (LAB) for analytical services and the Balance of Facilities (BOF) for plant maintenance, support and utility services. The transfer of staged feed from the waste storage tanks and acceptance in WTP receipt vessels require data for waste acceptance criteria (WAC) parameters from analysis of feed samples. The Data Quality Objectives (DQO) development was a joint team effort between WTP and Tank Operations Contractor (TOC) representatives. The focus of this DQO effort was to review WAC parameters and develop data quality requirements, the results of which will determine whether or not the staged feed can be transferred from the TOC to WTP receipt vessels. The approach involved systematic planning for data collection consistent with EPA guidance for the seven

The objective of the paper is threefold: (1) to introduce Landscape Quality Objectives (LQOs) as a set of indicators; (2) to present a method of linking social and expert opinion in the process of the formulation of landscape indicators; and (3) to present a methodological framework for the identification of LQOs. The implementation of these goals adopted a six-stage procedure based on the use of landscape units: (1) GIS analysis; (2) classification; (3) social survey; (4) expert value judgement; (5) quality assessment; and (6) guidelines formulation. The essence of the research was the presentation of features that determine landscape quality according to public opinion as a set of indicators. The results showed that 80 such indicators were identified, of both a qualitative (49) and a quantitative character (31). Among the analysed units, 60% (18 objects) featured socially expected (and confirmed by experts) levels of landscape quality, and 20% (6 objects) required overall quality improvement in terms of both public and expert opinion. The adopted procedure provides a new tool for integrating social responsibility into environmental management. The advantage of the presented method is the possibility of its application in the territories of various European countries. It is flexible enough to be based on cartographic studies, landscape research methods, and environmental quality standards existing in a given country. Copyright © 2016 Elsevier Ltd.

Mowlaee, Pejman; Saeidi, Rahim; Christensen, Mads Græsbøll

2012-01-01

Previous studies on performance evaluation of single-channel speech separation (SCSS) algorithms mostly focused on automatic speech recognition (ASR) accuracy as their performance measure. Assessing the separated signals by different metrics other than this has the benefit that the results...... are expected to carry on to other applications beyond ASR. In this paper, in addition to conventional speech quality metrics (PESQ and SNRloss), we also evaluate the separation systems output using different source separation metrics: blind source separation evaluation (BSS EVAL) and perceptual evaluation...... that PESQ and PEASS quality metrics predict well the subjective quality of separated signals obtained by the separation systems. From the results it is observed that the short-time objective intelligibility (STOI) measure predict the speech intelligibility results....

This paper proposes a no-reference objective stereoscopic video quality assessment method with the motivation that making the effect of objective experiments close to that of subjective way. We believe that the image regions with different visual salient degree should not have the same weights when designing an assessment metric. Therefore, we firstly use GBVS algorithm to each frame pairs and separate both the left and right viewing images into the regions with strong, general and week saliency. Besides, local feature information like blockiness, zero-crossing and depth are extracted and combined with a mathematical model to calculate a quality assessment score. Regions with different salient degree are assigned with different weights in the mathematical model. Experiment results demonstrate the superiority of our method compared with the existed state-of-the-art no-reference objective Stereoscopic video quality assessment methods.

Indicators to support the dynamic evaluation of air quality models

Science.gov (United States)

Thunis, P.; Clappier, A.

2014-12-01

Air quality models are useful tools for the assessment and forecast of pollutant concentrations in the atmosphere. Most of the evaluation process relies on the “operational phase” or in other words the comparison of model results with available measurements which provides insight on the model capability to reproduce measured concentrations for a given application. But one of the key advantages of air quality models lies in their ability to assess the impact of precursor emission reductions on air quality levels. Models are then used in a dynamic mode (i.e. response to a change in a given model input data) for which evaluation of the model performances becomes a challenge. The objective of this work is to propose common indicators and diagrams to facilitate the understanding of model responses to emission changes when models are to be used for policy support. These indicators are shown to be useful to retrieve information on the magnitude of the locally produced impacts of emission reductions on concentrations with respect to the “external to the domain” contribution but also to identify, distinguish and quantify impacts arising from different factors (different precursors). In addition information about the robustness of the model results is provided. As such these indicators might reveal useful as first screening methodology to identify the feasibility of a given action as well as to prioritize the factors on which to act for an increased efficiency. Finally all indicators are made dimensionless to facilitate the comparison of results obtained with different models, different resolutions, or on different geographical areas.

Pregnant women living with HIV represent one of the most high-priority groups for HIV treatment and health assessment. Although social support has been shown to be a protective factor for improved health-related quality of life (HRQoL), and depression and anxiety have been identified as two major causes of psychological distress among people living with HIV, it is still unclear how social support, anxiety, and depression interact to influence HRQoL. The objective of our study was to demonstrate the nature of predictors, direct effects and mediator effects among social support, anxiety, depression symptoms and HRQoL in pregnant women living with HIV. We investigated a total of 101 pregnant women living with HIV in Yunnan province in China from April 2016 to June 2016. All participants completed the Social Support Rating Scale (SSRS), the Chinese version of the Hospital Anxiety and Depression Scales (HADS) and Quality of Life instruments (EuroQoL Five Dimensions Questionnaire, EQ-5D). The relationships between the variables were examined by Pearson's or Spearman's correlation analysis. Predictor effects were tested using separate multiple regressions, controlling for demographic variables and HIV diagnosis variables. Direct and mediation effects of social support on HRQoL were tested using a structural equation model (SEM). Anxiety and depression symptoms were negatively correlated with subjective social support, support utilization, social support and HRQoL. Social support significantly predicted better HRQoL, and anxiety and depression symptoms significantly predicted poorer HRQoL. Anxiety and depression symptoms partially mediated the associations between social support and HRQoL. Anxiety and depression symptoms completely mediated the associations of objective support and support utilization with HRQoL. Interventions to improve HRQoL in pregnant women living with HIV must consider the mediation effect of anxiety and depression symptoms on the association between

To investigate the impact of the gap between subjective and objective social status on health-related quality of life. We analyzed data from 12,350 participants aged ≥ 18 years in the Korean Health Panel Survey. Health-related quality of life was measured by EuroQol-Visual analogue scale. Objective (income and education) and subjective social class (measured by MacArthur scale) was classified into three groups (High, Middle, Low). In terms of a gap between objective and subjective social class, social class was grouped into nine categories ranging from High-High to Low-Low. A linear mixed model was used to investigate the association between the combined social class and health-related quality of life. The impact of the gap between objective and subjective status on Health-related quality of life varied according to the type of gap. Namely, at any given subjective social class, an individual's quality of life declined with a decrease in the objective social class. At any given objective social class (e.g., HH, HM, HL; in terms of both education and income), an individual's quality of life declined with a one-level decrease in subjective social class. Our results suggest that studies of the relationship between social class and health outcomes may consider the multidimensional nature of social status.

Wedgeworth, Monika; LaRocca, Michael A; Chaplin, William F; Scogin, Forrest

The mental health of elderly individuals in rural areas is increasingly relevant as populations age and social structures change. While social support satisfaction is a well-established predictor of quality of life, interpersonal sensitivity symptoms may diminish this relation. The current study extends the findings of Scogin et al by investigating the relationship among interpersonal sensitivity, social support satisfaction, and quality of life among rural older adults and exploring the mediating role of social support in the relation between interpersonal sensitivity and quality of life (N = 128). Hierarchical regression revealed that interpersonal sensitivity and social support satisfaction predicted quality of life. In addition, bootstrapping resampling supported the role of social support satisfaction as a mediator between interpersonal sensitivity symptoms and quality of life. These results underscore the importance of nurses and allied health providers in assessing and attending to negative self-perceptions of clients, as well as the perceived quality of their social networks.

The processing mechanism of verbs-actions and nouns-objects is a central topic of language research, with robust evidence for behavioral dissociation. The neural basis for these two major word and/or conceptual classes, however, remains controversial. Two experiments were conducted to study this question from the network perspective. Experiment 1 found that nodes of the same class, obtained through task-evoked brain imaging meta-analyses, were more strongly connected with each other than nodes of different classes during resting-state, forming segregated network modules. Experiment 2 examined the behavioral relevance of these intrinsic networks using data from 88 brain-damaged patients, finding that across patients the relative strength of functional connectivity of the two networks significantly correlated with the noun-object vs. verb-action relative behavioral performances. In summary, we found that verbs-actions and nouns-objects are supported by separable intrinsic functional networks and that the integrity of such networks accounts for the relative noun-object- and verb-action-selective deficits.

Full Text Available Background: Health-related quality of life (HRQoL in cancer has been related to several protective and risk factors such as perceived social support (PSS and coping. However, their effects on HRQoL once patients are in survivorship have not been fully described in pediatric samples. Objective: To describe and explore the relationship between HRQoL in survivorship and some factors (PSS, coping present while active treatment. Methods: Cross-sectional study. Forty-one pediatric cancer survivors answered HRQoL measures referred to survivorship, as well as PSS and coping measures referred to treatment period. Results: The discriminant function obtained succeeds to correctly classify 78% of the sample. Survivors who showed high HRQoL were those who, in the hardest moment while hospitalization, perceived satisfactory emotional support (from nurses and did not deploy a wide range of active coping resources to cope with stressful events (only social action coping strategy showed a significant relationship with HRQoL. Conclusions and implications: Considering these outcomes, educational and counseling interventions to strengthen patients' social networks and supportive relationships are recommended, specially, among health providers (nurses. These results highlight the importance of not overlooking opportunities to address the emotional needs of patients while hospitalization, since a positive and endurable effect has been observed at survivorship.
Improvement of quality of 3D printed objects by elimination of microscopic structural defects in fused deposition modeling.

Directory of Open Access Journals (Sweden)

Evgeniy G Gordeev

Full Text Available Additive manufacturing with fused deposition modeling (FDM is currently optimized for a wide range of research and commercial applications. The major disadvantage of FDM-created products is their low quality and structural defects (porosity, which impose an obstacle to utilizing them in functional prototyping and direct digital manufacturing of objects intended to contact with gases and liquids. This article describes a simple and efficient approach for assessing the quality of 3D printed objects. Using this approach it was shown that the wall permeability of a printed object depends on its geometric shape and is gradually reduced in a following series: cylinder > cube > pyramid > sphere > cone. Filament feed rate, wall geometry and G-code-defined wall structure were found as primary parameters that influence the quality of 3D-printed products. Optimization of these parameters led to an overall increase in quality and improvement of sealing properties. It was demonstrated that high quality of 3D printed objects can be achieved using routinely available printers and standard filaments.
Improving Multi-Objective Management of Water Quality Tipping Points: Revisiting the Classical Shallow Lake Problem

Science.gov (United States)

Quinn, J. D.; Reed, P. M.; Keller, K.

2015-12-01

Recent multi-objective extensions of the classical shallow lake problem are useful for exploring the conceptual and computational challenges that emerge when managing irreversible water quality tipping points. Building on this work, we explore a four objective version of the lake problem where a hypothetical town derives economic benefits from polluting a nearby lake, but at the risk of irreversibly tipping the lake into a permanently polluted state. The trophic state of the lake exhibits non-linear threshold dynamics; below some critical phosphorus (P) threshold it is healthy and oligotrophic, but above this threshold it is irreversibly eutrophic. The town must decide how much P to discharge each year, a decision complicated by uncertainty in the natural P inflow to the lake. The shallow lake problem provides a conceptually rich set of dynamics, low computational demands, and a high level of mathematical difficulty. These properties maximize its value for benchmarking the relative merits and limitations of emerging decision support frameworks, such as Direct Policy Search (DPS). Here, we explore the use of DPS as a formal means of developing robust environmental pollution control rules that effectively account for deeply uncertain system states and conflicting objectives. The DPS reformulation of the shallow lake problem shows promise in formalizing pollution control triggers and signposts, while dramatically reducing the computational complexity of the multi-objective pollution control problem. More broadly, the insights from the DPS variant of the shallow lake problem formulated in this study bridge emerging work related to socio-ecological systems management, tipping points, robust decision making, and robust control.

The World Health Organization Quality of Life-BREF (WHOQOL-BREF) has generally been used for patients, few studies in migrants who move from rural to urban within one country. Many studies asserted that social isolation presents a risk to individual health. Poor social networks are associated with worse QOL. This study examined health-related quality of life (HRQOL) and social support in new-generation migrant workers and compared it with urban workers. Nine hundred thirty new-generation migrant workers and 939 urban controls completed the WHOQOL-BREF questionnaire and Social Support Rating Scale (SSRS) by stratified sampling in 2011. Spearman's correlation was performed to clarify the relationship between social support and HRQOL in migrants. Multiple linear regression analyses were used to identify the variables that were associated with HRQOL. The general health, psychological health, and environmental scores of QOL in new-generation migrant workers were lower than in urban workers. New-generation migrants had poorer social support compared with urban controls with regard to general support, objective support, and support utilization. A positive correlation was found between social support and HRQOL. Workers with a higher level of education achieved better psychological, environmental, and general scores than workers with a primary education. Physical, social, environmental, and general health was also closely connected with the age factor. Physical health scores were higher in males than in females. These data suggest that new-generation migrant workers have significant impairment in HRQOL and receive less social support. HRQOL may be affected by social support, education, age, and gender.

Presented are some of the critical issues and objectives pertaining to configuration management for the NASA Western Aeronautical Test Range (WATR) of Ames Research Center. The primary mission of the WATR is to provide a capability for the conduct of aeronautical research flight test through real-time processing and display, tracking, and communications systems. In providing this capability, the WATR must maintain and enforce a configuration management plan which is independent of, but complimentary to, various research flight test project configuration management systems. A primary WATR objective is the continued development of generic research flight test project support capability, wherein the reliability of WATR support provided to all project users is a constant priority. Therefore, the processing of configuration change requests for specific research flight test project requirements must be evaluated within a perspective that maintains this primary objective.

The increase in the access to biomedical interventions for people living with HIV/AIDS in the developing world has not been adequately matched with the requisite psychosocial treatments to help improve the effectiveness of biomedical interventions. Therefore, in this study the author seeks to determine whether socio-demographic characteristics and social support are associated with quality of life in individuals diagnosed with HIV/AIDS in Ghana. A convenience sample of 300 HIV/AIDS support group members was obtained via cross-sectional design survey. The Medical Outcome Studies (MOS) HIV Health Survey, the MOS Social Support Survey (MOS-SSS), and demographic questionnaire instruments were used to assess quality of life, social support, and demographic information respectively. Multiple regression analysis showed that there was a positive association between overall social support and overall quality of life (r = .51). It also showed that being younger, male, attending support group meetings for over a year, and having ≥ 13 years of schooling related to higher quality of life. Implications of the findings for practice, policy, and research in Ghana and the rest of the developing world are discussed.

Improvement of the R-SWAT-FME framework to support multiple variables and multi-objective functions

Wu, Yiping; Liu, Shu-Guang

2014-01-01

Application of numerical models is a common practice in the environmental field for investigation and prediction of natural and anthropogenic processes. However, process knowledge, parameter identifiability, sensitivity, and uncertainty analyses are still a challenge for large and complex mathematical models such as the hydrological/water quality model, Soil and Water Assessment Tool (SWAT). In this study, the previously developed R program language-SWAT-Flexible Modeling Environment (R-SWAT-FME) was improved to support multiple model variables and objectives at multiple time steps (i.e., daily, monthly, and annually). This expansion is significant because there is usually more than one variable (e.g., water, nutrients, and pesticides) of interest for environmental models like SWAT. To further facilitate its easy use, we also simplified its application requirements without compromising its merits, such as the user-friendly interface. To evaluate the performance of the improved framework, we used a case study focusing on both streamflow and nitrate nitrogen in the Upper Iowa River Basin (above Marengo) in the United States. Results indicated that the R-SWAT-FME performs well and is comparable to the built-in auto-calibration tool in multi-objective model calibration. Overall, the enhanced R-SWAT-FME can be useful for the SWAT community, and the methods we used can also be valuable for wrapping potential R packages with other environmental models.

Houzet Dominique

2005-01-01

Full Text Available The first aim of this work is to propose the design of a system-on-chip (SoC platform dedicated to digital image and signal processing, which is tuned to implement efficiently multiply-and-accumulate (MAC vector/matrix operations. The second aim of this work is to implement a recent promising neural network method, namely, the support vector machine (SVM used for real-time object recognition, in order to build a vision machine. With such a reconfigurable and programmable SoC platform, it is possible to implement any SVM function dedicated to any object recognition problem. The final aim is to obtain an automatic reconfiguration of the SoC platform, based on the results of the learning phase on an objects' database, which makes it possible to recognize practically any object without manual programming. Recognition can be of any kind that is from image to signal data. Such a system is a general-purpose automatic classifier. Many applications can be considered as a classification problem, but are usually treated specifically in order to optimize the cost of the implemented solution. The cost of our approach is more important than a dedicated one, but in a near future, hundreds of millions of gates will be common and affordable compared to the design cost. What we are proposing here is a general-purpose classification neural network implemented on a reconfigurable SoC platform. The first version presented here is limited in size and thus in object recognition performances, but can be easily upgraded according to technology improvements.

Full Text Available This article reports on experiments from our ongoing project whose goal is to develop a C++ library which supports adaptive and irregular data structures on distributed memory supercomputers. We demonstrate the use of our abstractions in implementing "tree codes" for large-scale N-body simulations. These algorithms require dynamically evolving treelike data structures, as well as load-balancing, both of which are widely believed to make the application difficult and cumbersome to program for distributed-memory machines. The ease of writing the application code on top of our C++ library abstractions (which themselves are application independent, and the low overhead of the resulting C++ code (over hand-crafted C code supports our belief that object-oriented approaches are eminently suited to programming distributed-memory machines in a manner that (to the applications programmer is architecture-independent. Our contribution in parallel programming methodology is to identify and encapsulate general classes of communication and load-balancing strategies useful across applications and MIMD architectures.

Humans have a massive capacity to store detailed information in visual long-term memory. The present studies explored the fidelity of these visual long-term memory representations and examined how conceptual and perceptual features of object categories support this capacity. Observers viewed 2,800 object images with a different number of exemplars presented from each category. At test, observers indicated which of 2 exemplars they had previously studied. Memory performance was high and remained quite high (82% accuracy) with 16 exemplars from a category in memory, demonstrating a large memory capacity for object exemplars. However, memory performance decreased as more exemplars were held in memory, implying systematic categorical interference. Object categories with conceptually distinctive exemplars showed less interference in memory as the number of exemplars increased. Interference in memory was not predicted by the perceptual distinctiveness of exemplars from an object category, though these perceptual measures predicted visual search rates for an object target among exemplars. These data provide evidence that observers' capacity to remember visual information in long-term memory depends more on conceptual structure than perceptual distinctiveness. 2010 APA, all rights reserved

Quality measurement is an important component of healthcare reform. The relationship of quality indicators (QIs) for parent-delivered family support services to organizational social contexts known to improve quality is unexamined. This study employs data collected from 21 child mental health programs that deliver team-based family support services. Performance on two levels of QIs —those targeting the program and staff -- were significantly associated with organizational social context profiles and dimensions. High quality program policies are associated with positive organizational cultures and engaging climates. Inappropriate staff practices are associated with resistant cultures. Implications for organizational strategies to improve service quality are discussed. PMID:23709286

Quality Management occupies a strategic role in organizations, and the adoption of computer tools within an aligned information architecture facilitates the challenge of making more with less, promoting the development of a competitive edge and sustainability. A formal Information Architecture (IA) lends organizations an enhanced knowledge but, above all, favours management. This simplifies the reinvention of processes, the reformulation of procedures, bridging and the cooperation amongst the multiple actors of an organization. In the present investigation work we planned the IA for the Quality Management System (QMS) of a Hospital, which allowed us to develop and implement the QUALITUS (QUALITUS, name of the computer application developed to support Quality Management in a Hospital Unit) computer application. This solution translated itself in significant gains for the Hospital Unit under study, accelerating the quality management process and reducing the tasks, the number of documents, the information to be filled in and information errors, amongst others.

Purpose - The purpose of this paper is to test the psychometric properties and dimensionality of the instrument Quality in Psychiatric Care-Housing (QPC-H) and briefly describe the residents' perception of quality of housing support. Design/methodology/approach - A sample of 174 residents from 22 housing support services in nine Swedish municipalities participated in the study. Confirmatory factor analysis (CFA) revealed that the QPC-H consisted of six dimensions and had a factor structure largely corresponding to that found among other instruments in the Quality in Psychiatric Care (QPC) family of instruments. Findings - CFA revealed that the QPC-H consisted of six dimensions and had a factor structure largely corresponding to that found among other instruments in the QPC family of instruments. The internal consistency of the factors was acceptable except in the case of secure and secluded environment, probably due to few numbers of items. With this exception, the QPC-H shows adequate psychometric properties. Social implications - The residents' ratings of quality of housing service were generally high; the highest rating was for secluded environment and the lowest for participation. This dimension would thus seem to indicate an important area for improvement. Originality/value - The QPC-H includes important aspects of residents' assessment of quality of housing service and offers a simple and inexpensive way to evaluate housing support services from the residents' perspective.

The objectives of this study were to examine which types of social supports - emotional/informational support, tangible support, affectionate support, and positive interactions - are the predictors of health-related quality of life (HRQoL) in adult patients with CHD and to assess the influence of demographic variables and clinical factors on these variables. In total, 205 adult patients with CHD from the National Heart Institute, Malaysia, were recruited. Patients were first screened by cardiology consultants to ensure they fit the inclusion criteria before filling in questionnaires, which were medical outcome studies - social support survey and AQoL-8D. Results/conclusions All social supports and their subscales were found to have mild-to-moderate significant relationships with physical dimension, psychological dimension, and overall HRQoL; however, only positive interaction, marital status, and types of diagnosis were reported as predictors of HRQoL. Surprisingly, with regard to the physical dimension of quality of life, social supports were not significant predictors, but educational level, marital status, and types of diagnosis were significant predictors. Positive interaction, affectionate support, marital status, and types of diagnosis were again found to be predictors in the aspects of the psychological dimension of quality of life. In conclusion, positive interaction and affectionate support, which include elements of fun, relaxation, love, and care, should be included in the care of adult patients with CHD.

The purpose of the study was two-fold: (1) to examine the relationships among self-care, social support, and quality of life in adult cancer patients receiving radiotherapy while the selected basic conditioning factors of age, marital and socio-economic status, living arrangement, stage and site of cancer were statistically controlled; and (2) to test a theoretical model which postulated that (a) quality of life was predicted jointly by the selected basic conditioning factors, social support and self-care, and (b) self-care was predicted jointly by the selected basic conditioning factors and social support. A convenience sample of 112 adult cervical and head/neck cancer patients receiving radiotherapy was obtained from radiotherapy outpatient clinic in three hospitals located in Bangkok, Thailand. Results of the study indicated positive relationships among self-care, social support, and quality of life. Socio-economic status, site of cancer, and self-care were significant predictors for reported quality of life. Social support appeared to be a significant predictor of quality of life indirectly through self-care. Socio-economic status and social support were also significant predictors of self-care, whereas, stage and site of cancer seemed to predict self-care indirectly through social support

This paper presents a fuzzy multi-criteria decision-making (FMCDM) model by integrating both subjective and objective weights for ranking and evaluating the service quality in hotels. The objective method selects weights of criteria through mathematical calculation, while the subjective method uses judgments of decision makers. In this paper, we use a combination of weights obtained by both approaches in evaluating service quality in hotel industries. A real case study that considered ranking five hotels is illustrated. Examples are shown to indicate capabilities of the proposed method.
Data quality objectives summary report for 105-N Basin sediment disposition

International Nuclear Information System (INIS)

Pisarcik, D.J.

1998-01-01

During stabilization of the 105-N Basin, sediments that have accumulated on 105-N Basin surfaces will be vacuumed, collected in the North Cask Pit of the basin complex, and eventually removed. The Environmental Assessment for the Deactivation of the N Reactor Facilities describes two potential disposition paths for the 105-N Basin sediment: transfer in slurry form to a double-shell tank if determined to be a transuranic waste, or disposal in solid form as a low-level waste. Interim storage of the sediments may be required if a transfer to the Tank Waste Remediation System cannot meet schedule milestones. Selection of a particular alternative depends on the final characterization of the accumulated sediment, regulatory requirements, cost/benefit analyses, and 105-N Stabilization Project schedule requirements. Revision 0 of this Data Quality Objectives (DQO) report was issued to describe a formal DQO process that was performed according to BHI-EE-01, Environmental Investigations Procedures, EIP 1.2, Data Quality Objectives, Revision 1. Since publication of Revision 0 of this report, important changes to the disposition strategy for 100-N Deactivation sediment material have been proposed, evaluated, discussed with the US Department of Energy and State of Washington Department of Ecology, and implemented. Revision 1 of this report documents these changes

Full Text Available Abstract Introduction: This is important to consider the health, social support, and marital satisfaction of drivers since they own one of the essential and stressful jobs in society. The purpose of this research was to investigate quality of life, marital satisfaction, and social support of the drivers referring to the cargo terminal of Yazd City. Methods: In order to collect data, 134 drivers in Yazd cargo terminal were selected. The ENRICH questionnaire of marital satisfaction, SF-36 questionnaire, and social support questionnaire (SSQ have been used as data collection tools. The collected data were then analyzed by Independent T test, Analysis of Variance (ANOVA, and Pearson correlation. Results: According to the results, the drivers' average age was 40.2±9.17 years old. The mean scores of marital satisfaction, quality of life, and social support were equal to 120.04±20.14 out of 175, 99.69±18.14 out of 149, and 15±4.76 out of 23, respectively. About 60.4 % of drivers were not satisfied with their jobs. There were significant relationships between weight and marital satisfaction (P=0.02, as well as between job satisfaction (P=0.003 (P=0.015 and income (P=0.047 (P=0.020, to social support and quality of life. Also, a strong significant positive relationship was observed in correlation coefficient between social support and two variables of quality of life and marital satisfaction (P=0.000. Conclusion: This can be argued that marital satisfaction, quality of life, and social support of the drivers are lower than the expected levels. Therefore, it can be concluded that physical and mental health of drivers can be effective on safety of roads; thereby it is necessary to improve their conditions in marital satisfaction, quality of life, and social support

Lu, Hai; Alanne, Kari; Martinac, Ivo

2014-01-01

Highlights: • Energy quality management is applied from individual building to district. • A novel time-effective multi-objective design optimization scheme is proposed. • The scheme searches for exergy efficient and environmental solution for districts. • System reliability is considered and addressed in this paper. - Abstract: Renewable energy systems entail a significant potential to meet the energy requirements of building clusters and districts (BCDs) provided that local energy sources are exploited efficiently. Besides improving the energy efficiency by reducing energy consumption and improving the match between energy supply and demand, energy quality issues have become a key topic of interest. Energy quality management is a technique that aims at optimally utilizing the exergy content of various renewable energy sources. In addition to minimizing life-cycle CO 2 emissions related to exergy losses of an energy system, issues such as system reliability should be addressed. The present work contributes to the research by proposing a novel multi-objective design optimization scheme that minimizes the global warming potential during the life-cycle and maximizes the exergy performance, while the maximum allowable level of the loss of power supply probability (LPSP) is predefined by the user as a constraint. The optimization makes use of Genetic Algorithm (GA). Finally, a case study is presented, where the above methodology has been applied to an office BCD located in Norway. The proposed optimization scheme is proven to be efficient in finding the optimal design and can be easily enlarged to encompass more relevant objective functions

The perceived quality of professional life is related to perception and regulation dimensions of Emotional Intelligence. Knowledge of emotion management methods should be promoted by management organisations for all employees. Copyright © 2015 Elsevier España, S.L.U. All rights reserved.
Chicago Residents' Perceptions of Air Quality: Objective Pollution, the Built Environment, and Neighborhood Stigma Theory.

Science.gov (United States)

King, Katherine E

2015-09-01

Substantial research documents higher pollution levels in minority neighborhoods, but little research evaluates how residents perceive their own communities' pollution risks. According to "Neighborhood stigma" theory, survey respondents share a cultural bias that minorities cause social dysfunction, leading to over-reports of dysfunction in minority communities. This study investigates perceptions of residential outdoor air quality by linking objective data on built and social environments with multiple measures of pollution and a representative survey of Chicago residents. Consistent with the scholarly narrative, results show air quality is rated worse where minorities and poverty are concentrated, even after extensive adjustment for objective pollution and built environment measures. Perceptions of air pollution may thus be driven by neighborhood socioeconomic position far more than by respondents' ability to perceive pollution. The finding that 63.5% of the sample reported excellent or good air quality helps to explain current challenging in promoting environmental action.

Objective Evidence of associations between social support and dietary intake among adolescents is mixed. This study examines relationships between social support for healthy and unhealthy eating from friends and parents, and associations with diet quality. Design Cross-sectional analysis of survey data. Setting Baltimore, MD. Participants 296 youth ages 9-15 years, 53% female, 91% African American, participating in the B’More Healthy Communities for Kids study. Main Outcome Measure(s) Primary dependent variable: Diet quality measured using Healthy Eating Index 2010 overall score, calculated from the Block Kids Food Frequency Questionnaire. Independent variables: Social support from parents and friends for healthy eating (4 questions analyzed as a scale) and unhealthy eating (3 questions analyzed individually), age, gender, race, and household income, reported via questionnaire. Analysis Adjusted multiple linear regressions. Alpha, pFriend and parent support for healthy eating did not have statistically significant relationships with overall HEI scores. Youth who reported their parents offering high fat foods or sweets more frequently had lower overall HEI scores (β=−1.65; SE=0.52; 95% CI: −2.66 to −0.63). Conclusions and Implications These results are novel and demonstrate the need for additional studies examining support for unhealthy eating. These preliminary findings may be relevant to researchers as they develop family-based nutrition interventions. PMID:26865358
Product Quality Modelling Based on Incremental Support Vector Machine

International Nuclear Information System (INIS)

Wang, J; Zhang, W; Qin, B; Shi, W

2012-01-01

Incremental Support vector machine (ISVM) is a new learning method developed in recent years based on the foundations of statistical learning theory. It is suitable for the problem of sequentially arriving field data and has been widely used for product quality prediction and production process optimization. However, the traditional ISVM learning does not consider the quality of the incremental data which may contain noise and redundant data; it will affect the learning speed and accuracy to a great extent. In order to improve SVM training speed and accuracy, a modified incremental support vector machine (MISVM) is proposed in this paper. Firstly, the margin vectors are extracted according to the Karush-Kuhn-Tucker (KKT) condition; then the distance from the margin vectors to the final decision hyperplane is calculated to evaluate the importance of margin vectors, where the margin vectors are removed while their distance exceed the specified value; finally, the original SVs and remaining margin vectors are used to update the SVM. The proposed MISVM can not only eliminate the unimportant samples such as noise samples, but also can preserve the important samples. The MISVM has been experimented on two public data and one field data of zinc coating weight in strip hot-dip galvanizing, and the results shows that the proposed method can improve the prediction accuracy and the training speed effectively. Furthermore, it can provide the necessary decision supports and analysis tools for auto control of product quality, and also can extend to other process industries, such as chemical process and manufacturing process.

statistical algorithm is a relatively simple and versatile, but lacks short-term skill critical for water quality and spill management. To improve short-term skill, OST will ultimately operate with meteorologically driven hydrologic forecasts provided by the National Weather Service (NWS). OST functionalities will support a wide range of DEP uses, including short term operational projections, outage planning and emergency management, operating rule development, and water supply planning. A core use of OST will be to inform reservoir management strategies to control and mitigate turbidity events while ensuring water supply reliability. OST will also allow DEP to manage its complex reservoir system to meet multiple objectives, including ecological flows, tailwater fisheries and recreational releases, and peak flow mitigation for downstream communities.

The purpose of this data quality objectives (DQO) process is to support decision-making activities as they pertain to the demolition and disposition (or disposal) of the uncoated 108-F Biological Laboratory masonry block walls. The objective of DQO Step 1 is to use the information gathered from the DQO scoping process and other relevant information to clearly and concisely state the problem to be resolved. The free-form text sections included in this step are intended to define the project objectives and assumptions, present the project issues, summarize the facility background information, and provide a concise statement of the problem. The tables provided in this section are designed to document the personnel involved in the DQO process, identify the contaminants of concern, and summarize the key information needed to support the writing of the problem statement. The purpose of DQO Step 2 is to define the principal study question (PSQ) that needs to be resolved to address the problem identified in DQO Step 1 and to define the alternative actions that would result from the resolution of the PSQ. The PSQ and alternative actions are combined into a decision statement that expresses a choice among alternative actions. The purpose of DQO Step 3 is to identify the type of data needed to resolve the decision statement identified in DQO Step 2, as well as the analytical performance requirements (e.g., practical quantitation limit [PQL] requirement, precision, and accuracy) for the data. If it is determined that the required data do not already exist, the data may either be derived from computational or surveying/sampling and analysis methods. The primary objective of DQO Step 4 is for the DQO Team to identify the geographic (spatial) and temporal boundaries of the facility under investigation, as well as practical constraints (i.e., hindrances or obstacles) that must be taken into consideration in the surveying design. Implementing this step ensures that the surveying
Power quality measurement service in the support of large customers

Power quality and how it is measured among Hydro Quebec's major customers were the focus of this conference presentation. Background information on Hydro Quebec and its customers was provided with reference to information on clients, employees and how the organization is organized. The presentation also included a discussion of power quality and how it is delivered at Hydro Quebec. For example, characteristics and target values of the voltage supplied by Hydro Quebec for high, medium and low voltages were examined. Personnel responsible for the grid have created a system to document each event submitted by customers. Documenting the actual power quality at the point of common coupling allows benchmarking of real data against announced characteristics and target values. This approach quantifies disturbances and helps to find and focus on disturbances that really influence large customers, mainly industrials. Portable and permanent installations issues were discussed followed by a discussion of a new service offering power quality metering on a regular basis. This metering service includes a complete analysis and technical support with dedicated expertise since customers are rarely fully experienced in power quality. The metering service is presented from the perspective of preventive maintenance with continuous quantification of a large number of indicators to assess the quality of the delivered power. Essential tools that customers can benefit from with this new service include real time electronic mail notification, weekly reporting and ad hoc technical support. This combination of various levels of services allows Hydro-Quebec to address the needs of these large customers in a flexible way. figs.

To study efficacy and predictability of toric IOL implantation for correction of preoperative corneal astigmatism by analysing spherocylindrical refractive precision and objective quality of vision. Prospective study of 13 eyes undergoing micro-incisional cataract surgery through a 1.8mm corneal incision with toric IOL implantation (Lentis L313T(®), Oculentis) to treat over one D of preoperative corneal astigmatism. Preoperative evaluation included keratometry, subjective refraction, and total and corneal aberrometry (KR-1(®), Topcon). Six months postoperatively, measurements included slit lamp photography, documenting IOL rotation, tilt or decentration, uncorrected visual acuity, best-corrected visual acuity and objective quality of vision measurement (OQAS(®) Visiometrics, Spain). Postoperatively, mean uncorrected distance visual acuity was 8.33/10 ± 1.91 (0.09 ± 0.11 LogMar). Mean postoperative refractive sphere was 0.13 ± 0.73 diopters. Mean refractive astigmatism was -0.66 ± 0.56 diopters with corneal astigmatism of 2.17 ± 0.68 diopters. Mean IOL rotation was 4.4° ± 3.6° (range 0° to 10°). Mean rotation of this IOL at 6 months was less than 5°, demonstrating stability of the optic within the capsular bag. Objective quality of vision measurements were consistent with subjective uncorrected visual acuity. Implantation of the L313T(®) IOL is safe and effective for correction of corneal astigmatism in 1.8mm micro-incisional cataract surgery. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

This skill is performed in such a way that the graduates, after entering the practical professional life, will be able to participate in solutions for actual problems that are related to environmental protection by means of software support. Nowadays, during the training processit is also obligatory to introduce technical science. Taking into consideration the above-mentioned facts it is possible to say that information technology support for environmental study subjects is a relevant aspect, which should be integrated into the university educational process. There is an effective progress that further highlights the focus on the quality of university education not only for environmental engineers. Actual trends require an increasing number of software/hardware educated engineers who can participate in qualitative university preparation, i.e.IT environmentalists. The Department of Environmental Engineering at the Faculty of Mechanical Engineering, TechnicalUniversity in Košice, Slovakia is an institution specified and intended for quality objectivisation. This institution introduced into the study programmes (“Environmental Management” and “Technology of Environmental Protection” study subjects with the software support, which are oriented towards outdoor and indoor ambient and in this way the Department of Process and Environmental Engineering is integrated effectively and intensively into the area of measurement training with regard to the requirement of quality educational processes.

Full Text Available Abstract Background The regulations of the Quality Management System (QMS implementation in health care organizations were approved by the Lithuanian Ministry of Health in 1998. Following the above regulations, general managers of health care organizations had to initiate the QMS implementation in hospitals. As no research on the QMS implementation has been carried out in Lithuanian support treatment and nursing hospitals since, the objective of this study is to assess its current stage from a managerial perspective. Methods A questionnaire survey of general managers of Lithuanian support treatment and nursing hospitals was carried out in the period of January through March 2005. Majority of the items included in the questionnaire were measured on a seven-point Likert scale. During the survey, a total of 72 questionnaires was distributed, out of which 58 filled-in ones were returned (response rate 80.6 per cent; standard sampling error 0.029 at 95 per cent level of confidence. Results Quality Management Systems were found operating in 39.7 per cent of support treatment and nursing hospitals and currently under implementation in 46.6 per cent of hospitals (13.7% still do not have it. The mean of the respondents' perceived QMS significance is 5.8 (on a seven-point scale. The most critical issues related to the QMS implementation include procedure development (5.5, lack of financial resources (5.4 and information (5.1, and development of work guidelines (4.6, while improved responsibility and power sharing (5.2, better service quality (5.1 and higher patient satisfaction (5.1 were perceived by the respondents as the key QMS benefits. The level of satisfaction with the QMS among the management of the surveyed hospitals is mediocre (3.6. However it was found to be higher among respondents who were more competent in quality management, were familiar with ISO 9000 standards, and had higher numbers of employees trained in quality management.

Data quality objectives for moisture measurement in stabilized special nuclear material

Weier, D.R.; Pulsipher, B.A.; Silvers, K.L.

Data Quality Objectives methodology is applied to Loss-on-Ignition (LOI) moisture content testing for stabilized nuclear materials. This work was performed by Pacific Northwest National Laboratory in support of the Plutonium Finishing Plant (PFP)/Fluor Hanford, Inc. Historical results on LOI test results for two material types, oxide and sludge, are used to estimate within container variability. This variability estimate is then used in formulating the two recommended acceptance criteria for containers of material. The criteria which follow are proposed to replace the current criterion, which requires recycle if either of two container LOI measurements exceed 0.5 wt%, the DOE Standard 3013-99 threshold value. (1) The 95% upper confidence limit (UCL) for the true mean underlying moisture content in the container material should be less than 0.5 wt%. (2) The difference between the two LOI measurements per container should not exceed their expected 95th percentile relative to the estimated variability. Containers not meeting the first criterion, or those that generate in any negative LOI result, require material recycle. Containers not meeting the second criteria require review of the measurement results, potentially leading to resampling and retesting. Data from Los Alamos National Laboratory studies on moisture testing are obtained and analyzed. The performance of Supercritical Fluid Extraction (SFE), which will soon be implemented at the PFP, is described for several material types. This information will be used to establish initial acceptance criteria when SFE comes on line
Data quality objectives for two risk assessments at Hanford

1996-01-01

The opportunity for innovative thinking prevails at the US Department of Energy's Hanford Site in southeastern Washington state. Two projects, in particular, challenged risk assessment staff. They are: (1) a combined Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)/Resource Conservation and Recovery Act (RCRA) risk assessment, and (2) developing a risk assessment for a mixed-waste disposal facility. The combined CERCLA/RCRA risk assessment involved establishing data quality objectives (DQO) either to meet clean closure for a RCRA treatment, storage and/or disposal facility (TSD) or (if the former was not possible) to conform to goals established for industrial land use for Hanford Past-Practice Strategy (HPPS) sites. Radionuclide analysis was reduced by 60 percent through the DQO process

Object-centered representations support flexible exogenous visual attention across translation and reflection.

Visual attention can be deployed to stimuli based on our willful, top-down goal (endogenous attention) or on their intrinsic saliency against the background (exogenous attention). Flexibility is thought to be a hallmark of endogenous attention, whereas decades of research show that exogenous attention is attracted to the retinotopic locations of the salient stimuli. However, to the extent that salient stimuli in the natural environment usually form specific spatial relations with the surrounding context and are dynamic, exogenous attention, to be adaptive, should embrace these structural regularities. Here we test a non-retinotopic, object-centered mechanism in exogenous attention, in which exogenous attention is dynamically attracted to a relative, object-centered location. Using a moving frame configuration, we presented two frames in succession, forming either apparent translational motion or in mirror reflection, with a completely uninformative, transient cue presented at one of the item locations in the first frame. Despite that the cue is presented in a spatially separate frame, in both translation and mirror reflection, behavioralperformance in visual search is enhanced when the target in the second frame appears at the same relative location as the cue location than at other locations. These results provide unambiguous evidence for non-retinotopic exogenous attention and further reveal an object-centered mechanism supporting flexible exogenous attention. Moreover, attentional generalization across mirror reflection may constitute an attentional correlate of perceptual generalization across lateral mirror images, supporting an adaptive, functional account of mirror images confusion.

Hellén-Halme, Kristina; Johansson, Curt; Nilsson, Mats

2016-05-01

The main aim of this study was to evaluate the performance of 10 individual sensors of the same make, using objective measures of key image quality parameters. A further aim was to compare 8 brands of sensors. Ten new sensors of 8 different models from 6 manufacturers (i.e., 80 sensors) were included in the study. All sensors were exposed in a standardized way using an X-ray tube voltage of 60 kVp and different exposure times. Sensor response, noise, low-contrast resolution, spatial resolution and uniformity were measured. Individual differences between sensors of the same brand were surprisingly large in some cases. There were clear differences in the characteristics of the different brands of sensors. The largest variations were found for individual sensor response for some of the brands studied. Also, noise level and low contrast resolution showed large variations between brands. Sensors, even of the same brand, vary significantly in their quality. It is thus valuable to establish action levels for the acceptance of newly delivered sensors and to use objective image quality control for commissioning purposes and periodic checks to ensure high performance of individual digital sensors.

Data Quality Objectives for Regulatory Requirements for Hazardous and Radioactive Air Emissions Sampling and Analysis

International Nuclear Information System (INIS)

MULKEY, C.H.

1999-01-01

This document describes the results of the data quality objective (DQO) process undertaken to define data needs for state and federal requirements associated with toxic, hazardous, and/or radiological air emissions under the jurisdiction of the River Protection Project (RPP). Hereafter, this document is referred to as the Air DQO. The primary drivers for characterization under this DQO are the regulatory requirements pursuant to Washington State regulations, that may require sampling and analysis. The federal regulations concerning air emissions are incorporated into the Washington State regulations. Data needs exist for nonradioactive and radioactive waste constituents and characteristics as identified through the DQO process described in this document. The purpose is to identify current data needs for complying with regulatory drivers for the measurement of air emissions from RPP facilities in support of air permitting. These drivers include best management practices; similar analyses may have more than one regulatory driver. This document should not be used for determining overall compliance with regulations because the regulations are in constant change, and this document may not reflect the latest regulatory requirements. Regulatory requirements are also expected to change as various permits are issued. Data needs require samples for both radionuclides and nonradionuclide analytes of air emissions from tanks and stored waste containers. The collection of data is to support environmental permitting and compliance, not for health and safety issues
Effect of geometrical features various objects on the data quality obtained with measured by TLS

Collecting data on different building structures using Terrestrial Laser Scanning (TLS) has become in recent years a very popular due to minimize the time required to complete the task as compared to traditional methods. Technical parameters of 3D scanning devices (digitizers) are increasingly being improved, and the accuracy of the data collected allows you to play not only the geometry of an existing object in a digital image, but also enables the assessment of his condition. This is possible thanks to the digitalization of existing objects e.g., a 3D laser scanner, with which is obtained a digital data base is presented in the form of a cloud of points and by using reverse engineering. Measurements using laser scanners depends to a large extent, on the quality of the returning beam reflected from the target surface, towards the receiver. High impact on the strength and quality of the beam returning to the geometric features of the object. These properties may contribute to the emergence of some, sometimes even serious errors during scanning of various shapes. The study defined the effect of the laser beam distortion during the measurement objects with the same material but with different geometrical features on their three-dimensional imaging obtained from measurements made using TLS. We present the problem of data quality, dependent on the deflection of the beam intensity and shape of the object selected examples. The knowledge of these problems allows to obtain valuable data necessary for the implementation of digitization and the visualization of virtually any building structure made of any materials. The studies has been proven that the increase in the density of scanning does not affect the values of mean square error. The increase in the angle of incidence of the beam onto a flat surface, however, causes a decrease in the intensity of scattered radiation that reaches the receiver. The article presents an analysis of the laser beam reflected from broken at

Disasters can have an enormous impact on the health and well-being of those affected. Internationally, governments and service providers are often challenged to address complex psychosocial problems. Ideally, the potentially broad range of support activities include a coherent, high-quality mental health and psychosocial support (MHPSS) programme. We present a theory-driven quantitative analysis of the quality of 40 MHPSS programmes, mostly implemented in European disaster settings. The objective is to measure quality domains recognized as relevant in the literature and to empirically test associations. During the EU project "Operationalizing Psychosocial Support in Crisis" (OPSIC) an evaluation survey was designed and developed for this purpose and completed by 40 MHPSS programme coordinators involved in different mass emergencies and disasters. We analysed the survey data in two steps. Firstly, we used the data to operationalize quality domains of a MHPSS programme, tested constructs and assessed their internal consistency reliability. A total of 26 out of 44 survey items clustered into three of the four domains identified within the theoretical framework: "planning and delivery system" (Cronbach's alpha 0.82); "general evaluation criteria" (Cronbach's alpha 0.82); and "essential psychosocial principles" (Cronbach's alpha 0.75). "Measures and interventions applied", theoretically a potential fourth domain, could not be confirmed to empirically cluster together. Secondly, several models with associations between domains and measures and interventions were tested and compared. The model with the best fit suggests that in MHPSS programmes with a higher planning and delivery systems score, a larger number of measures and interventions from evidence-informed guidelines are applied. In such programmes, coordinators are more positive about general evaluation criteria and the realization of essential psychosocial principles. Moreover, the analyses showed that some
COMPARATIVE ANALISYS BETWEEN THE OBJECTIVE AND THE SUBJECTIVE QUALITY OF LIFE APPROACH - STRENGTHS AND WEAKNESSES

Full Text Available Quality of Life (QOL can be defined as the degree in which the objective needs of an individual are satisfied in relation with the subjective perspective of his well-being. Thus, there are two different approaches in QOL evaluation: the objective approach (which analyzes the quality of life through economic indicators and the subjective approach (which evaluates quality through the individuals opinion and actions. There isn't a widely accepted view referring to the use of one of those two QOL approaches, each having a series of strengths and weaknesses. This paper presents a comparative analysis of the advantages and disadvantages brought by these two approaches in QOL studies. The objective analysis has a series of strengths (among which we mention the fact that allows valide comparisons and the fact that doesn't depend on individuals perception, but has also a series of weaknesses, starting with the dependence on statistical data, which in many cases has incomplete registrations,and ending with the fact that doesn't reflect the real value of the well-being perceived by population. The motives for which the QOL subjective approach is promoted, therefore its strenghts, refer to the fact that it reflects important experiences for each individual and the fact that it reveals how macroeconomic policies satify the individual's needs. Certainly, this type of QOL analysis has also some weaknesses, like the lack of validity and accuracy in the data collected through surveys. Considering all the above, there is a conclusion with a wide aplication in the present context of the economy: we can't make a clear delineation between the two QOL approaches, moreover we can state the fact that the is a strong correlation between those two. Thus, the most precise systems of quality of life evaluation are those which use both objective, and subjective indicators, reaching a high level of aggregation at the national and international level.
Is the Moderating Effect of Social Support on New Korean Mothers' Psychological Distress Contingent on Levels of Marital Quality?

Park, Ki Tae

2018-03-01

This study examines how levels of marital quality change the effect of social support on postpartum psychological distress among new Korean mothers using the Panel Study on Korean Children (N = 1585). In accord with findings from previous studies, this study shows that low marital quality negatively affects new mothers' mental health, but that social support alleviates psychological distress independent of marital quality. The main finding of this research is that the moderating effect of social support is contingent on levels of marital quality. Aggregated social support moderates the effects of marital quality on new mothers' mental health only when the level of marital quality is low. Furthermore, each dimension of social support (emotional, informational, and instrumental) only has a moderating effect when marital quality is low. The findings highlight the fact that the moderating effect of social support varies with the individual context and so customized social support that fits individual needs matters for the mental health of new mothers.

Housing programs for people with severe mental illnesses aim to maximize community integration. However, little is known about how the community integration of mental health consumers living in supported housing compares with that of other community residents in the socially disadvantaged communities where supported housing is often located. The purpose of this study was to examine predictors of objective community integration of mental health consumers living in supported housing and of other persons living in the same communities. Participants were 124 adults (60 mental health consumers and 64 other community residents) residing in designated zip codes in the Bronx, New York. Participants were administered measures of psychiatric symptoms, substance use, physical community integration (participation in local activities), social integration (interactions with community members), and citizenship (political activism or volunteering). Mental health consumers living in supported independent housing had significantly lower scores on indicators of objective community integration than other community members. However, differences were relatively small. Among mental health consumers, African-American race, education, and length of time in current residence were associated with better community integration. Findings suggest that mental health consumers living in supported housing may not achieve levels of objective community integration that are comparable with other community members; however, psychiatric factors did not account for this difference. Length of time in neighborhoods appears to be an important factor in facilitating social integration.
Strategy to Support Improvement of Healthcare Quality.

Full Text Available One of the latest market-based solutions to the rising costs and quality gaps in health care is pay for performance. Pay for performance is the use of financial incentives to promote the delivery of designated standards of care. It is an emerging movement in health insurance (initially in Britain and United States. Providers under this arrangement are rewarded for meeting pre-established targets for delivery of healthcare services. This is a fundamental change from fee for service payment.Also known as "P4P" or “value-based purchasing,” this payment model rewards physicians, hospitals, medical groups, and other healthcare providers for meeting certain performance measures for quality and efficiency. Disincentives, such as eliminating payments for negative consequences of care (medical errors or increased costs, have also been proposed. In the developed nations, the rapidly aging population and rising health care costs have recently brought P4P to the forefront of health policy discussions. Pilot studies underway in several large healthcare systems have shown modest improvements in specific outcomes and increased efficiency, but no cost savings due to added administrative requirements. Statements by professional medical societies generally support incentive programs to increase the quality of health care, but express concern with the validity of quality indicators, patient and physician autonomy and privacy, and increased administrative burdens. This article serves as an introduction to pay for performance. We discuss the goals and structure of pay for performance plans and their limitations and potential consequences in the health care area.
Quality research in healthcare: are researchers getting enough statistical support?

Directory of Open Access Journals (Sweden)

Ambler Gareth

2006-01-01

Full Text Available Abstract Background Reviews of peer-reviewed health studies have highlighted problems with their methodological quality. As published health studies form the basis of many clinical decisions including evaluation and provisions of health services, this has scientific and ethical implications. The lack of involvement of methodologists (defined as statisticians or quantitative epidemiologists has been suggested as one key reason for this problem and this has been linked to the lack of access to methodologists. This issue was highlighted several years ago and it was suggested that more investments were needed from health care organisations and Universities to alleviate this problem. Methods To assess the current level of methodological support available for health researchers in England, we surveyed the 25 National Health Services Trusts in England, that are the major recipients of the Department of Health's research and development (R&D support funding. Results and discussion The survey shows that the earmarking of resources to provide appropriate methodological support to health researchers in these organisations is not widespread. Neither the level of R&D support funding received nor the volume of research undertaken by these organisations showed any association with the amount they spent in providing a central resource for methodological support for their researchers. Conclusion The promotion and delivery of high quality health research requires that organisations hosting health research and their academic partners put in place funding and systems to provide appropriate methodological support to ensure valid research findings. If resources are limited, health researchers may have to rely on short courses and/or a limited number of advisory sessions which may not always produce satisfactory results.
Identification of physical properties for the retrieval data quality objective process

Gates, C.M.; Beckette, M.R.

1995-06-01

This activity supports the retrieval data quality objective (DQO) process by identifying the material properties that are important to the design, development, and operation of retrieval equipment; the activity also provides justification for characterizing those properties. These properties, which control tank waste behavior during retrieval operations, are also critical to the development of valid physical simulants for designing retrieval equipment. The waste is to be retrieved in a series of four steps. First, a selected retrieval technology breaks up or dislodges the waste into subsequently smaller pieces. Then, the dislodged waste is conveyed out of the tank through the conveyance line. Next, the waste flows into a separator unit that separates the gaseous phase from the liquid and solid phases. Finally, a unit may be present to condition the slurried waste before transporting it to the treatment facility. This document describes the characterization needs for the proposed processes to accomplish waste retrieval. Baseline mobilization technologies include mixer pump technology, sluicing, and high-pressure water-jet cutting. Other processes that are discussed in this document include slurry formation, pneumatic conveyance, and slurry transport. Section 2.0 gives a background of the DQO process and the different retrieval technologies. Section 3.0 provides the mechanistic descriptions and material properties critical to the different technologies and processes. Supplemental information on specific technologies and processes is provided in the appendices. Appendix A contains a preliminary sluicing model, and Appendices B and C cover pneumatic transport and slurry transport, respectively, as prepared for this document. Appendix D contains sample calculations for various equations
A new approach of objective quality evaluation on JPEG2000 lossy-compressed lung cancer CT images

Image compression has been used to increase the communication efficiency and storage capacity. JPEG 2000 compression, based on the wavelet transformation, has its advantages comparing to other compression methods, such as ROI coding, error resilience, adaptive binary arithmetic coding and embedded bit-stream. However it is still difficult to find an objective method to evaluate the image quality of lossy-compressed medical images so far. In this paper, we present an approach to evaluate the image quality by using a computer aided diagnosis (CAD) system. We selected 77 cases of CT images, bearing benign and malignant lung nodules with confirmed pathology, from our clinical Picture Archiving and Communication System (PACS). We have developed a prototype of CAD system to classify these images into benign ones and malignant ones, the performance of which was evaluated by the receiver operator characteristics (ROC) curves. We first used JPEG 2000 to compress these cases of images with different compression ratio from lossless to lossy, and used the CAD system to classify the cases with different compressed ratio, then compared the ROC curves from the CAD classification results. Support vector machine (SVM) and neural networks (NN) were used to classify the malignancy of input nodules. In each approach, we found that the area under ROC (AUC) decreases with the increment of compression ratio with small fluctuations.
Data quality objectives summary report for the 105-n basin liquid disposition

During stabilization of the 105-N Basin, basin waters (1 million gallons) will be filtered and transported to the 200 Area Effluent Treatment Facility (ETF) for treatment and disposal. Hazardous chemicals are not considered to be present in the water; filtration is planned to reduce the suspended solids load and radionuclide concentrations. ETF has provided the Environmental Restoration Contractor with a list of constituents that must be analyzed in the 105-N Basin water; however, there are no specific concentration criteria established for these constituents. Analysis is required primarily to establish treatment parameters and to monitor radionuclide activity. A sampling program is required that will: (1) characterize the water quality in the 105-N Basin for the identified parameters, and (2) verifies that water quality does not change due to intrusive activities being performed concurrent with water drawdown. The Data Quality Objectives Process for the 105-N Basin water is being used to establish an approach for characterizing the water and monitoring the parameters of concern for water sent to the ETF

Objective assessment of image quality VI: imaging in radiation therapy

Barrett, Harrison H; Kupinski, Matthew A; Müeller, Stefan; Halpern, Howard J; Morris, John C III; Dwyer, Roisin

2013-01-01

Earlier work on objective assessment of image quality (OAIQ) focused largely on estimation or classification tasks in which the desired outcome of imaging is accurate diagnosis. This paper develops a general framework for assessing imaging quality on the basis of therapeutic outcomes rather than diagnostic performance. By analogy to receiver operating characteristic (ROC) curves and their variants as used in diagnostic OAIQ, the method proposed here utilizes the therapy operating characteristic or TOC curves, which are plots of the probability of tumor control versus the probability of normal-tissue complications as the overall dose level of a radiotherapy treatment is varied. The proposed figure of merit is the area under the TOC curve, denoted AUTOC. This paper reviews an earlier exposition of the theory of TOC and AUTOC, which was specific to the assessment of image-segmentation algorithms, and extends it to other applications of imaging in external-beam radiation treatment as well as in treatment with internal radioactive sources. For each application, a methodology for computing the TOC is presented. A key difference between ROC and TOC is that the latter can be defined for a single patient rather than a population of patients. (paper)
Performance evaluation of objective quality metrics for HDR image compression

Science.gov (United States)

Valenzise, Giuseppe; De Simone, Francesca; Lauga, Paul; Dufaux, Frederic

2014-09-01

Due to the much larger luminance and contrast characteristics of high dynamic range (HDR) images, well-known objective quality metrics, widely used for the assessment of low dynamic range (LDR) content, cannot be directly applied to HDR images in order to predict their perceptual fidelity. To overcome this limitation, advanced fidelity metrics, such as the HDR-VDP, have been proposed to accurately predict visually significant differences. However, their complex calibration may make them difficult to use in practice. A simpler approach consists in computing arithmetic or structural fidelity metrics, such as PSNR and SSIM, on perceptually encoded luminance values but the performance of quality prediction in this case has not been clearly studied. In this paper, we aim at providing a better comprehension of the limits and the potentialities of this approach, by means of a subjective study. We compare the performance of HDR-VDP to that of PSNR and SSIM computed on perceptually encoded luminance values, when considering compressed HDR images. Our results show that these simpler metrics can be effectively employed to assess image fidelity for applications such as HDR image compression.

Clinical data warehouses, initially directed towards clinical research or financial analyses, are evolving to support quality improvement efforts, and must now address the quality improvement life cycle. In addition, data that are needed for quality improvement often do not reside in a single database, requiring easier methods to query data across multiple disparate sources. We created a virtual data warehouse at NewYork Presbyterian Hospital that allowed us to bring together data from several source systems throughout the organization. We also created a framework to match the maturity of a data request in the quality improvement life cycle to proper tools needed for each request. As projects progress in the Define, Measure, Analyze, Improve, Control stages of quality improvement, there is a proper matching of resources the data needs at each step. We describe the analysis and design creating a robust model for applying clinical data warehousing to quality improvement.

This is the second revision of the DQO Supporting Radiological Air Emissions Monitoring for the Pacific Northwest National Laboratory Richland Campus. In January 2017, the PNNL Richland Campus expanded to the north by 0.35 km² (85.6 acres). Under the requirements of Washington State Department of Health Radioactive Air Emissions License (RAEL)-005, the PNNL Campus operates and maintains a radiological air monitoring program. This revision documents and evaluates the newly acquired acreage while also removing recreational land at the southwest, and also re-examines all active radioactive emission units on the PNNL Campus. No buildings are located on this new Campus land, which was transferred from the U.S. DOE Hanford Site. Additionally, this revision includes information regarding the background monitoring station PNL-5 in Benton City, Washington, which became active in October 2016. The key purpose of this revision is to determine the adequacy of the existing environmental surveillance stations to monitor radiological air emissions in light of this northern boundary change.

Although recent randomized controlled trials support early palliative care for patients with advanced cancer, the specific processes of care associated with these findings and whether these improvements can be replicated in the broader health care system are uncertain. The aim of this study was to evaluate the occurrence of palliative care consultation and its association with specific processes of supportive care in a national cohort of Veterans using the Cancer Quality ASSIST (Assessing Symptoms Side Effects and Indicators of Supportive Treatment) measures. We abstracted data from 719 patients' medical records diagnosed with advanced lung, colorectal, or pancreatic cancer in 2008 over a period of three years or until death who received care in the Veterans Affairs Health System to evaluate the association of palliative care specialty consultation with the quality of supportive care overall and by domain using a multivariate regression model. All but 54 of 719 patients died within three years and 293 received at least one palliative care consult. Patients evaluated by a palliative care specialist at diagnosis scored seven percentage points higher overall (P specialist consultation is associated with better quality of supportive care in three advanced cancers, predominantly driven by improvements in information and care planning. This study supports the effectiveness of early palliative care consultation in three common advanced cancers within the Veterans Affairs Health System and provides a greater understanding of what care processes palliative care teams influence.

Noton, L.; McEachern, P.

2004-01-01

This paper addressed environmental concerns related to the increased oil sands activity along the lower Athabasca River in northeastern Alberta. The concerns include potential effects on water quality of the river even though wastewaters do not currently reach the Athabasca River, nor do they have any significant effects. However, as the industry expands, there is concern that releases of wastewater may increase significantly. A multi-stakeholder group called the Cumulative Environmental Management Association (CEMA) has addressed some of these environmental management issues in the Athabasca area by establishing a water quality task group that examines water quality protection and management activities. The task group intends to develop and recommend water quality objectives and management options on the lower Athabasca River. Their 4 part process includes: (1) defining the problem, (2) setting goals, (3) measuring performance, and (4) managing and adapting to potential impacts. The group has identified and defined about 35 water quality variables of potential concern. It has also identified the uses of water it wants to protect and intends to prevent the degradation of water quality. A plan for developing site specific water quality objectives has been established following a review of water quality guidelines. Performance will be measured using water quality models that simulate full development scenarios. The modelling work will be instrumental in designing management schemes for any potential impacts

The paper shows that discussion given in the MM issue July/August 2013 does not fulfill expectations expressed in MM issue 2011. The presented paper is the review on maintenance that is based on condition monitoring as tool for detection of faults and failure prevention. Fault and failure are regarded as inevitable during the machine operation as the process of wear and the process of degradation. The question is, if one can influence the wear and degradation process, using condition monitoring. The paper will present technology (in reference to cited papers which demonstrates that the use of the proper method can influence the wear and machine degradation process, using proper condition monitoring techniques and knowing scenarios of wear and degradation process, the maintenance can be rationalized. The presented paper shows possible improvements which are needed to fulfill expectations expressed in MM September 2011 and they are not taken into consideration in MM July/August 3013. These improvements can be fulfilling on the bases of object and operation supported maintenance.
Can state-of-the-art HVS-based objective image quality criteria be used for image reconstruction techniques based on ROI analysis?

Dostal, P.; Krasula, L.; Klima, M.

2012-06-01

Various image processing techniques in multimedia technology are optimized using visual attention feature of the human visual system. Spatial non-uniformity causes that different locations in an image are of different importance in terms of perception of the image. In other words, the perceived image quality depends mainly on the quality of important locations known as regions of interest. The performance of such techniques is measured by subjective evaluation or objective image quality criteria. Many state-of-the-art objective metrics are based on HVS properties; SSIM, MS-SSIM based on image structural information, VIF based on the information that human brain can ideally gain from the reference image or FSIM utilizing the low-level features to assign the different importance to each location in the image. But still none of these objective metrics utilize the analysis of regions of interest. We solve the question if these objective metrics can be used for effective evaluation of images reconstructed by processing techniques based on ROI analysis utilizing high-level features. In this paper authors show that the state-of-the-art objective metrics do not correlate well with subjective evaluation while the demosaicing based on ROI analysis is used for reconstruction. The ROI were computed from "ground truth" visual attention data. The algorithm combining two known demosaicing techniques on the basis of ROI location is proposed to reconstruct the ROI in fine quality while the rest of image is reconstructed with low quality. The color image reconstructed by this ROI approach was compared with selected demosaicing techniques by objective criteria and subjective testing. The qualitative comparison of the objective and subjective results indicates that the state-of-the-art objective metrics are still not suitable for evaluation image processing techniques based on ROI analysis and new criteria is demanded.

2011-09-01

To determine the age-related pattern of well-being among men and its predictors in a subsistence society, we collected anthropometric and questionnaire data among Ariaal pastoral nomads of northern Kenya. The sample consisted of 102 settled and 103 nomadic men ages 20 to 60+ stratified by 10 year age groups. Measures included questions from the WHO quality of life questionnaire (WHOQOL), anthropometrics, and hand grip strength, as well as questions about the number of friends and kin who gave material and emotional support. Results show that while reported quality of life declined significantly across age groups in both sub-populations, nomadic males reported significantly higher overall quality of life than did settled males. Support from other males, but not marital status, was a significant predictor of quality of life, controlled for age group and residence. Among the physical measures, % body fat was positively related to quality of life among the nomads, while grip strength was not related to quality of life. In a multivariate model, male support was the strongest predictor of quality of life. These results provide the first clear demonstration of age-related declines in male quality of life and the importance of social support to men's quality of life in a subsistence population.

Objective: To analyze the differences between the social support for breast cancer patients and healthy female, and to explore the correlation between social support and quality of life (QOL) in the patients. Methods: From January 2013 to December 2014, 101 patients with operable breast cancer treated at Xinyu City People's Hospital were recruited as the experimental group. They completed questionnaires in the preoperative, postoperative chemoradiotherapy and rehabilitation periods, respectively.101 healthy female volunteers recruited from the community were included as control group, whose age and level of education were matched with those of the experimental group.The general questionnaire including basic information, disease conditions and other projects, perceived social support scale (PSSS), quality of life of breast cancer patients (FACT-B) were applied to evaluate the general situation, social support and QOL of the subjects. The differences in PSSS scores between the experimental and control groups were compared. The correlation between PSSS score and FACT-B score in the experimental group was analyzed. SPSS 18.0 software was used for statistical analysis. Results: The general situations of the experimental and control groups were comparable (all P >0.05). The rates of the total social support score ≥50 in the experimental and control groups were not significantly different (93.6% vs. 94.7%, P =0.067). Compared with that of the control group (23.2±4.8), the scores of family support in the experimental group in preoperative, postoperative chemoradiotherapy and rehabilitation periods were statistically higher (25.6±3.2, 24.2±4.2 and 24.0±3.4, respectively, P =0.034). The social support scores of patients with different demographic characteristics were different. Among the demographic characteristics, years of education and place of residence had the largest impact. The scores of social support in patients with longer education years and living in the

Engineering performance indicators in support of corporate goals and objectives

Prawlocki, F.C.; Holland, M.B.

1992-01-01

In the late 1980s, a new factor was introduced into the equation of rate making: competition. Prior to this time, most utilities only had to prove to the state public service commission (PSC) that a rate increase was justified. Even this had become more difficult in recent years as PSCs implemented prudency audits as a means of determining the efficiency of utility management. Recently, however, the need for performance improvement has been initiated internally by utility management because of the advent of competition in the utility environment and state PSC inquiries. In 1991, TVA began to realign its traditional program of performance indicators to agree with industry standards and provide more extensive indicators of positive and negative trends in performance. The INPO Guideline 88-016, Guidelines for the Conduct of Design Engineering, was used as the basis for most indicators. In addition, indicators were added to highlight specific corporate objectives, problems, or regulatory commitments. The indicators are being initiated in three phases as efficient sources of performance data are identified. Once the current baseline was established, a review was made of the best utilities in the country based on the US Nuclear Regulatory Commission's systematic assessment of licensee's performance and INPO performance indicators to establish performance goals. As total quality management and cycle time reduction programs are implemented, all of the organization's annual goals and objectives are expected to more closely reflect the best of the industry

Family members are the most important source of social support for cancer patients. The determinants of family support, however, are not well understood. In this study, the associations of anger-expression styles of both patients and their partners with patient-perceived partner support and the impact of these variables on long-term health-related quality of life (HRQL) of the patient were examined. The baseline data were collected at the time of diagnosis; a follow-up survey was conducted at 8 months. Questionnaires included the Spielberger AX scale, the Family Support scale, and the RAND-36 Health Survey. The sample comprised 153 patients and their partners. The theoretical model was tested with a path analysis using structural equation modeling, and gender differences were tested using multivariate analysis of covariance. Path analyses indicated that partner support was an important mediator, partly explaining the associations between anger-expression styles and HRQL. As hypothesized, anger control had a positive relationship with perceived partner support, while habitual inhibition of anger (anger-in) showed a negative correlation with partner support. Analyses by gender revealed some clear differences: for the male patients, the wife's high level of anger expression (anger-out) was significantly positively related to patient mental HRQL, whereas for the female patients, their husband's anger-out was negatively correlated with the patient's mental HRQL. In addition, patient's own anger-out had a more pronounced negative effect on HRQL for women as compared to men. The anger-expression styles of both patients and their partners seem to modify the family atmosphere, and together, they are important determinants of the long-term quality of life of the cancer patients. Interventions for couples facing cancer should include a focus on ways of dealing with anger and thereby support dyadic coping with cancer.

(a) To find out how much patient information material on display in family physicians' offices refers to management choices, and hence may be useful to support informed and shared decision-making (ISDM) by patients and (b) to evaluate the quality of print information materials exchanged during the consultation, i.e. brought in by patients or given out by family physicians. All print information available for patients and exchanged between physicians and patients was collected in a single complete day of the office practices of 21 family physicians. A published and validated instrument (DISCERN) was used to assess quality. Community office practices in the greater Vancouver area, British Columbia, Canada. The physicians were purposefully recruited by their association with the medical school Department of Family Practice, their interest in providing patients with print information and their representation of a range of practice types and location. The source of the pamphlets and these categories: available in the physicians' offices; exchanged between physician and patient; and produced with the explicit or apparent intent to support evidence-based patient choice. The quality of the print information to support ISDM, as measured by DISCERN and the ease of use and reliability of the DISCERN tool. Fewer than 50% of pamphlets available in these offices fulfilled our minimum criteria for ISDM (mentioned more than one management option). Offices varied widely in the proportion of pamphlets on display that supported ISDM and how particular the physician was in selecting materials. The DISCERN tool is quick, valid and reliable for the evaluation of patient information. The quality of patient information materials used in the consultation and available in these offices was below midpoint on the DISCERN score. Major deficiencies were with respect to the mention of choices, risks, effect of no treatment or uncertainty and reliability (source, evidence-base). Good quality

This study was designed to identify the degree to which the directors of adult basic education programs perceive they have program quality support, as evidenced by a well-defined mission and role in the community, a management system, human resources management, and a suitable learning environment. NSCALL's Evidence-based program self-assessment (2006) was modified and administered electronically to administrators of adult education programs in a mid-southern state. Findings indicated that most directors perceive they are implementing the indicators of program quality support in all of the areas surveyed. A research-based annual self-study that considers the quality indicators is recommended, leaving a need for an update to the NCSALL assessment for use as a program assessment instrument.

Air quality, like weather, can affect everyone, but responses differ depending on the sensitivity and health condition of a given individual. To help protect exposed populations, many countries have put in place real-time air quality nowcasting and forecasting capabilities. We present in this paper an optimal combination of air quality measurements and model outputs and show that it leads to significant improvements in the spatial representativeness of air quality. The product is referred to as multi-pollutant surface objective analyses (MPSOAs). Moreover, based on MPSOA, a geographical mapping of the Canadian Air Quality Health Index (AQHI) is also presented which provides users (policy makers, public, air quality forecasters, and epidemiologists) with a more accurate picture of the health risk anytime and anywhere in Canada and the USA. Since pollutants can also behave as passive atmospheric tracers, they provide information about transport and dispersion and, hence, reveal synoptic and regional meteorological phenomena. MPSOA could also be used to build air pollution climatology, compute local and national trends in air quality, and detect systematic biases in numerical air quality (AQ) models. Finally, initializing AQ models at regular time intervals with MPSOA can produce more accurate air quality forecasts. It is for these reasons that the Canadian Meteorological Centre (CMC) in collaboration with the Air Quality Research Division (AQRD) of Environment Canada has recently implemented MPSOA in their daily operations.
Associations Between Parental SES and Children's Health-Related Quality of Life: The Role of Objective and Subjective Social Status.

We examined (1) the relationship that parental objective social status (OSS) and subjective social status (SSS) have with children's health-related quality of life (HRQOL), (2) whether SSS mediates the association between OSS and HRQOL, and (3) whether these associations differ among Black, Latino, and White children. Data came from 4,824 Black, Latino, and White 5th graders in the Healthy PassagesTM study. OSS was measured as parent educational attainment and net equivalent household income. SSS was measured by parent rating of community and national standing on the MacArthur Scale of Subjective Social Status. Child HRQOL was measured with child report on the Pediatric Quality of Life Inventory (PedsQL) physical and psychosocial scales. Structural equation modeling path analysis was conducted using Mplus version 7.4. The data supported the hypothesized measurement and structural models. Whereas parental OSS was positively related to psychosocial HRQOL for all three racial/ethnic groups and to physical HRQOL for Latino children, parental SSS was not related to either for any of the racial/ethnic groups. Therefore, mediation by SSS was not supported for any group. OSS was confirmed to have stronger association with children's HRQOL than parental SSS. This is in contrast to some research on adults, raising the questions of how best to assess SSS relevant to children and at what point in development SSS may influence children's health and well-being. The persistent relationship found between parental OSS and child health suggests that efforts to improve low socioeconomic resources in families may contribute to improve children's health.

To examine the impact of state/territory policy support on (1) uptake of evidence-based continuous quality improvement (CQI) activities and (2) quality of care for Indigenous Australians. Mixed-method comparative case study methodology, drawing on quality-of-care audit data, documentary evidence of policies and strategies and the experience and insights of stakeholders involved in relevant CQI programmes. We use multilevel linear regression to analyse jurisdictional differences in quality of care. Indigenous primary healthcare services across five states/territories of Australia. 175 Indigenous primary healthcare services. A range of national and state/territory policy and infrastructure initiatives to support CQI, including support for applied research. PRIMARY AND SECONDARY OUTCOME MEASURES: (i) Trends in the consistent uptake of evidence-based CQI tools available through a research-based CQI initiative (the Audit and Best Practice in Chronic Disease programme) and (ii) quality of care (as reflected in adherence to best practice guidelines). Progressive uptake of evidence-based CQI activities and steady improvements or maintenance of high-quality care occurred where there was long-term policy and infrastructure support for CQI. Where support was provided but not sustained there was a rapid rise and subsequent fall in relevant CQI activities. Health authorities should ensure consistent and sustained policy and infrastructure support for CQI to enable wide-scale and ongoing improvement in quality of care and, subsequently, health outcomes. It is not sufficient for improvement initiatives to rely on local service managers and clinicians, as their efforts are strongly mediated by higher system-level influences. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Data quality objective to support resolution of the organic fuel rich tank safety issue

International Nuclear Information System (INIS)

Buckley, L.L.

1995-01-01

During years of Hanford process history, large quantities of complexants used in waste management operations as well as an unknown quantity of degradation products of the solvents used in fuel reprocessing and metal recovery were added to man of the 149 single-shell tanks. These waste tanks also contain a presumed stoichiometric excess of sodium nitrate/nitrite oxidizers, sufficient to exothermically oxidize the organic compounds if suitably initiated. This DQO identifies the questions that must be answered to appropriately disposition organic watchlist tanks, identifies a strategy to deal with false positive or negative judgements associated with analytical uncertainty, and list the analytes of concern to support dealing with organic watchlist concerns. Uncertainties associated with both assay limitations and matrix effects complicate selection of analytes. This results in requiring at least two independent measures of potential fuel reactivity

Transgender individuals experience discrimination in all domains of their personal and social life. Discrimination is believed to be associated with worse quality of life (QoL). To investigate the relation between QoL and perceived levels of discrimination and social support in individuals with gender dysphoria (GD). Individuals with GD who attended a psychiatry clinic from January 2012 through December 2014 were recruited. Demographic, social, and medical transition features were collected with standardized forms. Self-report measurements of QoL (Turkish version of the World Health Organization's Quality of Life-BREF) that included physical, psychological, social, and environmental domains, perceived discrimination with personal and group subscales (Perceived Discrimination Scale [PDS]), and social support (Multidimensional Scale of Perceived Social Support) were completed. Ninety-four participants (76.6% trans men) adequately completed the study measurements. Regression models with each QoL domain score as a dependent variable indicated a significant predictor value of personal PDS in social and environmental QoL. Social support from family was associated with better QoL in psychological QoL, whereas perceived support from friends significantly predicted all other domains of QoL. There was a tendency for group PDS to be rated higher than personal PDS, suggesting personal vs group discrimination discrepancy. However, group PDS was not found to be a predictor of QoL in the multivariate model. Perceived personal discrimination and social support from different sources predicted domains of QoL with a non-uniform pattern in individuals with GD. Social support and discrimination were found to have opposing contributions to QoL in GD. The present findings emphasize the necessity of addressing discrimination and social support in clinical work with GD. Moreover, strategies to improve and strengthen friend and family support for individuals with GD should be explored by

The proposed National Health Insurance policy for South Africa (SA) requires hospitals to maintain high-quality International Statistical Classification of Diseases (ICD) codes for patient records. While considerable strides had been made to improve ICD coding coverage by digitising the discharge process in the Western Cape Province, further intervention was required to improve data quality. The aim of this controlled before-and-after study was to evaluate the impact of a clinician training and support initiative to improve ICD coding quality. To compare ICD coding quality between two central hospitals in the Western Cape before and after the implementation of a training and support initiative for clinicians at one of the sites. The difference in differences in data quality between the intervention site and the control site was calculated. Multiple logistic regression was also used to determine the odds of data quality improvement after the intervention and to adjust for potential differences between the groups. The intervention had a positive impact of 38.0% on ICD coding completeness over and above changes that occurred at the control site. Relative to the baseline, patient records at the intervention site had a 6.6 (95% confidence interval 3.5 - 16.2) adjusted odds ratio of having a complete set of ICD codes for an admission episode after the introduction of the training and support package. The findings on impact on ICD coding accuracy were not significant. There is sufficient pragmatic evidence that a training and support package will have a considerable positive impact on ICD coding completeness in the SA setting.

The Air Quality Strategy for England, Scotland, Wales and Northern Ireland (DETR, 2001) has the aim of showing how improved local air quality in the UK may be delivered. Through a process of reviewing and assessing local air quality in both urban and rural localities, a clear picture is emerging of areas of the UK where air quality objectives are not likely to be met. The next challenge will be the identification of the required actions and new ways of working to achieve specific air quality objectives. The declaration of air quality management areas, where objectives are not predicted to be met by their target years, involves co-ordinated local action and collaborative working, which can only be effective with support across local authority departments and external stake holders. This paper provides a background to the relevant legislation underpinning, local air quality management and summarises the review and assessment process. It then comments on future directions in relation to the designation of Air Quality Management Areas and considers the requirements of action plans to deliver the goal of cleaner air in the UK. It is concluded that the UK has developed a highly sophisticated system of air quality management over a relatively short period of time, and with it has brought a new way of local authority working. The challenge of the next stage of the process is likely to be in implementing cost effective and proportional solutions to identified problems at the local level. (Author)
A comparison between the cost curves in the RAINS-model and the Swedish environmental quality objectives

The Swedish Parliament has adopted fifteen environmental quality objectives. To be able to attain these goals in a cost-efficient way, cost curves have been created for sulphur dioxide (SO 2 ), nitrogen oxides (NO x ), and volatile organic compounds (VOC). These pollutants are also restricted in international protocols under the Convention on Long-Range Transboundary Air Pollution (CLRTAP). Most of the analyses underlying the protocols have been performed by the Regional Acidification Information and Simulation model (RAINS) developed at the International Institute for Applied Systems Analysis (IIASA) in Austria. This study compare the cost-effectiveness principles used in the RAINS model with the principles used in the proposal to meet the Swedish environmental quality objectives. The two approaches use different methodologies to solve the problem with air pollution and do therefore receive different results. The advantages and disadvantages are discussed in this report
Bootstrap Signal-to-Noise Confidence Intervals: An Objective Method for Subject Exclusion and Quality Control in ERP Studies

Analysis of event-related potential (ERP) data includes several steps to ensure that ERPs meet an appropriate level of signal quality. One such step, subject exclusion, rejects subject data if ERP waveforms fail to meet an appropriate level of signal quality. Subject exclusion is an important quality control step in the ERP analysis pipeline as it ensures that statistical inference is based only upon those subjects exhibiting clear evoked brain responses. This critical quality control step is most often performed simply through visual inspection of subject-level ERPs by investigators. Such an approach is qualitative, subjective, and susceptible to investigator bias, as there are no standards as to what constitutes an ERP of sufficient signal quality. Here, we describe a standardized and objective method for quantifying waveform quality in individual subjects and establishing criteria for subject exclusion. The approach uses bootstrap resampling of ERP waveforms (from a pool of all available trials) to compute a signal-to-noise ratio confidence interval (SNR-CI) for individual subject waveforms. The lower bound of this SNR-CI (SNRLB) yields an effective and objective measure of signal quality as it ensures that ERP waveforms statistically exceed a desired signal-to-noise criterion. SNRLB provides a quantifiable metric of individual subject ERP quality and eliminates the need for subjective evaluation of waveform quality by the investigator. We detail the SNR-CI methodology, establish the efficacy of employing this approach with Monte Carlo simulations, and demonstrate its utility in practice when applied to ERP datasets. PMID:26903849

This article discusses the background and process for developing a multi-year corporate quality plan. The Ottawa Hospital's goal is to be a top 10% performer in quality and patient safety in North America. In order to create long-term measurable and sustainable changes in the quality of patient care, The Ottawa Hospital embarked on the development of a three-year strategic corporate quality plan. This was accomplished by engaging the organization at all levels and defining quality frameworks, aligning with internal and external expectations, prioritizing strategic goals, articulating performance measurements and reporting to stakeholders while maintaining a transparent communication process. The plan was developed through an iterative process that engaged a broad base of health professionals, physicians, support staff, administration and senior management. A literature review of quality frameworks was undertaken, a Quality Plan Working Group was established, 25 key stakeholder interviews were conducted and 48 clinical and support staff consultations were held. The intent was to gather information on current quality initiatives and challenges encountered and to prioritize corporate goals and then create the quality plan. Goals were created and then prioritized through an affinity exercise. Action plans were developed for each goal and included objectives, tasks and activities, performance measures (structure, process and outcome), accountabilities and timelines. This collaborative methodology resulted in the development of a three-year quality plan. Six corporate goals were outlined by the tenets of the quality framework for The Ottawa Hospital: access to care, appropriate care (effective and efficient), safe care and satisfaction with care. Each of the six corporate goals identified objectives and supporting action plans with accountabilities outlining what would be accomplished in years one, two and three. The three-year quality plan was approved by senior

The Data Quality Objectives (DQO) process used for this 107-N Basin Recirculation Building liquid/sediment DQO report followed BHI-EE-01, Environmental Investigations Procedures, EIIP 1.2, Data Quality Objectives, Revision 2. Tri-Party Agreement Milestone (M-16-OIE) states that the 100-N Area deactivation must be performed according to the work scope identified in the N Reactor Deactivation Program Plan (WHC 1993c). Consistent with the N Reactor Deactivation Program Plan, the scope of the 107-N liquid/sediment DQO process exclusively involves the determination of sampling requirements during the deactivation period. The sampling requirements are primarily directed at characterization for comparison to decontamination and decommissioning endpoint acceptance criteria in preparation for turnover of the facilities listed below to the D and D organization. The sample characterization will also be used for selection of the appropriate disposition option for liquid and sediment currently contained in the facility. The primary media within the scope of this DQO includes the following: Accumulated liquids and sediment contained in tanks, vessels, pump wells, sumps, associated piping, and valve pit floors; and Limited solid debris (anticipated to be discovered)

Object reconstruction is a important task in many fields of application as it allows to generate digital representations of our physical world used as base for analysis, planning, construction, visualization or other aims. A reconstruction itself normally is based on reliable data (images, 3D point clouds for example) expressing the object in his complete extension. This data then has to be compiled and analyzed in order to extract all necessary geometrical elements, which represent the object and form a digital copy of it. Traditional strategies are largely based on manual interaction and interpretation, because with increasing complexity of objects human understanding is inevitable to achieve acceptable and reliable results. But human interaction is time consuming and expensive, why many research has already been invested to integrate algorithmic support, what allows to speed up the process and reduce manual work load. Presently most such algorithms are data-driven and concentrate on specific features of the objects, being accessible to numerical models. By means of these models, which normally will represent geometrical (flatness, roughness, for example) or physical features (color, texture), the data is classified and analyzed. This is succesful for objects with a limited complexity, but gets to its limits with increasing complexity of objects. Then purely numerical strategies are not able to sufficiently model the reality. Therefore, the intention of our approach is to take human cogni-tive strategy as an example, and to simulate extraction processes based on available knowledge for the objects of interest. Such processes will introduce a semantic structure for the objects and guide the algorithms used to detect and recognize objects, which will yield a higher effectiveness. Hence, our research proposes an approach using knowledge to guide the algorithms in 3D point cloud and image processing.

Objectives To examine whether the association between emotional support and indicators of health and quality of life differs between Canadian and Latin American older adults. Design Cross-sectional analysis of the International Mobility in Aging Study (IMIAS). Social support from friends, family members, children and partner was measured with a previously validated social network and support scale (IMIAS-SNSS). Low social support was defined as ranking in the lowest site-specific quartile. Prevalence ratios (PR) of good health, depression and good quality of life were estimated with Poisson regression models, adjusting for age, gender, education, income and disability in activities of daily living. Setting Kingston and Saint-Hyacinthe in Canada, Manizales in Colombia and Natal in Brazil. Participants 1600 community-dwelling adults aged 65–74 years, n=400 at each site. Outcome measures Likert scale question on self-rated health, Center for Epidemiological Studies Depression Scale and 10-point analogical quality-of-life (QoL) scale. Results Relationships between social support and study outcomes differed between Canadian and Latin American older adults. Among Canadians, those without a partner had a lower prevalence of good health (PR=0.90; 95% CI 0.82 to 0.98), and those with high support from friends had a higher prevalence of good health (PR=1.09; 95% CI 1.01 to 1.18). Among Latin Americans, depression was lower among those with high levels of support from family (PR=0.63; 95% CI 0.48 to 0.83), children (PR=0.60; 95% CI 0.45 to 0.80) and partner (PR=0.57; 95% CI 0.31 to 0.77); good QoL was associated with high levels of support from children (PR=1.54; 95% CI 1.20 to 1.99) and partner (PR=1.31; 95% CI 1.03 to 1.67). Conclusions Among older adults, different sources of support were relevant to health across societies. Support from friends and having a partner were related to good health in Canada, whereas in Latin America, support from family, children and

Among the 106 MtF gender dysphoric individuals of Sanggar Swara Jakarta with an age range of 18-45 years, 78.3% had no family support, 64.1% no peer support, 62.3% high perception discrimination, 64.1% low self-esteem, 36% extreme family relations, 44.3% depression, 59.4% anxiety, 35.8% stress and 62.3% poor quality of life. Employment, perception of discrimination, self-esteem, family support, and anxiety were significantly associated with quality of life (p<0.05. Multiple logistic regression analysis showed that perceived discrimination (Odds Ratio=13.89; 95% CI: 5.89-11.99, and family support (Odds Ratio=29.11; 95% CI: 2.45-8.21 were significantly associated with quality of life. Conclusion High perceived discrimination and no family support increase the risk of poor quality of life in MtF gender dysphoric individuals. These findings suggest the need for prevention and intervention of stigmatization and discrimination that should have a special focus on families with MtF gender dysphoric individuals.

A global interest in developing these interventions exists among both for-profit and not-for-profit organisations. It is therefore essential to have internationally accepted standards to assess the quality of their development, process, content, potential bias and method of field testing and evaluation.Scale development study, involving construct, item and scale development, validation and reliability testing.Twenty-five researcher-members of the International Patient Decision Aid Standards Collaboration worked together to develop the instrument (IPDASi. In the fourth Stage (reliability study, eight raters assessed thirty randomly selected decision support technologies.IPDASi measures quality in 10 dimensions, using 47 items, and provides an overall quality score (scaled from 0 to 100 for each intervention. Overall IPDASi scores ranged from 33 to 82 across the decision support technologies sampled (n = 30, enabling discrimination. The inter-rater intraclass correlation for the overall quality score was 0.80. Correlations of dimension scores with the overall score were all positive (0.31 to 0.68. Cronbach's alpha values for the 8 raters ranged from 0.72 to 0.93. Cronbach's alphas based on the dimension means ranged from 0.50 to 0.81, indicating that the dimensions, although well correlated, measure different aspects of decision support technology quality. A short version (19 items was also developed that had very similar mean scores to IPDASi and high correlation between short score and overall score 0.87 (CI 0.79 to 0.92.This work

Objectives (a) To find out how much patient information material on display in family physicians’ offices refers to management choices, and hence may be useful to support informed and shared decision‐making (ISDM) by patients and (b) to evaluate the quality of print information materials exchanged during the consultation, i.e. brought in by patients or given out by family physicians. Design All print information available for patients and exchanged between physicians and patients was collected in a single complete day of the office practices of 21 family physicians. A published and validated instrument (DISCERN) was used to assess quality. Setting and participants Community office practices in the greater Vancouver area, British Columbia, Canada. The physicians were purposefully recruited by their association with the medical school Department of Family Practice, their interest in providing patients with print information and their representation of a range of practice types and location. Main variables studied The source of the pamphlets and these categories: available in the physicians’ offices; exchanged between physician and patient; and produced with the explicit or apparent intent to support evidence‐based patient choice. Main outcome measures The quality of the print information to support ISDM, as measured by DISCERN and the ease of use and reliability of the DISCERN tool. Results and conclusions Fewer than 50% of pamphlets available in these offices fulfilled our minimum criteria for ISDM (mentioned more than one management option). Offices varied widely in the proportion of pamphlets on display that supported ISDM and how particular the physician was in selecting materials. The DISCERN tool is quick, valid and reliable for the evaluation of patient information. The quality of patient information materials used in the consultation and available in these offices was below midpoint on the DISCERN score. Major deficiencies were with

Since the original characterization of the ventral visual pathway, our knowledge of its neuroanatomy, functional properties, and extrinsic targets has grown considerably. Here we synthesize this recent evidence and propose that the ventral pathway is best understood as a recurrent occipitotemporal network containing neural representations of object quality both utilized and constrained by at least six distinct cortical and subcortical systems. Each system serves its own specialized behavioral, cognitive, or affective function, collectively providing the raison d'être for the ventral visual pathway. This expanded framework contrasts with the depiction of the ventral visual pathway as a largely serial staged hierarchy culminating in singular object representations and more parsimoniously incorporates attentional, contextual, and feedback effects.

Based on the self-determination theory (Ryan & Deci, 2000), this study tested a model of the assumed sequential relationships between perceived autonomy support, psychological need satisfaction, self-determined motivation, and enjoyment/boredom. The hypothesized mediational roles of psychological need satisfaction and self-determined motivation were also studied. In a sample of 370 young male soccer players, path analysis results offered support for the proposed model. Total mediation was supported in the case of the psychological need satisfaction in the relationship between autonomy support and self-determined motivation, and partial mediation for self-determined motivation in the links between psychological need satisfaction and enjoyment (positive) and boredom (negative). Implications of autonomy-supportive behaviors provided by coaches for the quality of sport involvement among young athletes are discussed.

An extensive quality assurance program to provide high quality data and assessments in support of the Marshall Islands Dose Assessment and Radioecology Program has been developed the Lawrence Livermore National Laboratory. Quality assurance objectives begin with the premise of providing integrated and cost-effective program support (to meet wide-ranging programmatic needs, scientific peer review, and build public confidence) and continue through from design and implementation of large-scale field programs, sampling and sample preparation, radiometric and chemical analyses, documentation of quality assurance/quality control practices, exposure assessments, and dose/risk assessments until publication. The basic structure of the radioassay quality assurance/quality control program can be divided into four essential elements: (1) sample and data integrity control, (2) instrument validation and calibration, (3) method performance testing, validation, development and documentation, and (4) periodic peer review and on-site assessments. While the quality assurance objectives are tailored towards a single research program and the evaluation of major exposure pathways/critical radionuclides pertinent to the Marshall Islands, quality assurance practices that are consistent with proposed criteria designed for laboratory accreditation were attempted to be developed.

Personality and social support (SS) influence risk for depression and modify its outcome through multiple pathways. The impact of personality dimensions neuroticism and extraversion on SS among patients with major depressive disorder (MDD) has been little studied. In the Vantaa Depression Study, we assessed neuroticism and extraversion with the Eysenck Personality Inventory, objective SS with the Interview Measure of Social Relationships, and subjective SS with the Perceived Social Support Scale-Revised at baseline, at 6 and 18 months among 193 major depressive disorder patients diagnosed according to the fourth edition of Diagnostic and Statistical Manual of Mental Disorders (DMS-IV). At all time-points, low neuroticism and high extraversion associated significantly with between-subject differences in levels of objective and subjective SS. Lower neuroticism (beta = 0.213, p = 0.003) and higher extraversion (beta = 0.159, p = 0.038) predicted greater within-subject change of subjective, but not objective SS. Thus, neuroticism and extraversion associated with the size of objective and subjective SS and predicted change of subjective SS. Modification of subjective SS, particularly, may indirectly influence future vulnerability to depression.
IMPROVEMENT OF QUALITY OF LIFE AS THE MAIN OBJECTIVE OF ALLERGIC RHINITIS THERAPY IN CHILDREN

Full Text Available Traditionally, efficacy of treating allergic rhinitis (AR in children is evaluated on the basis of subjective and objective criteria connected with the more or less express character of symptoms. At the same time, there are all reasons to say that the evaluation of the quality of life (QOL of a child more fully reflects his health than sole consideration of AR symptoms. As a result, the change of QOL in the course of treating AR may more precisely reflect the efficacy of illness treatment. This is especially noticeable when analyzing the results of treatment with the use of sedative antihistamine drugs, which arrest AR symptoms but exert a negative influence over the QOL indicators, such as activity, learning ability, social adaptation. New generation antihistamine drugs and intranasal corticosteroids do not have such influence over children's QOL. moreover, their regular use may help in decreasing the risk of development bronchial asthma and atopic dermatitis in children, which is another objective of AR therapy.Key words: children, quality of life, allergic rhinitis, treatment.

The evaluation of the environmental quality objective 'A Safe Radiation Environment' is a contribution to the Environmental Objective Council's assessment of progress towards the national environmental quality objectives. The report describes and evaluates the radiation environment in Sweden, the regulatory instruments, measures carried out and the monitoring programmes. Furthermore, the possibility of achieving the objective and its interim targets is evaluated. New measures and means of control are proposed. The proposals are directed to the government and Parliament, national authorities and other stakeholders in society. The Swedish Radiation Protection Authority (SSI) considers it possible to achieve the objective, but additional efforts are required to ensure success. Environmental monitoring, research on health effects of radiation and supervision are still important areas. Intensified efforts will be needed to change attitudes towards suntanning. Changes in the formulation of the objective and its interim targets are suggested. Today only protection against radiation in the external environment is covered by the objective. Radiation protection work has to consider all. SSI therefore suggests that the objective should extend to include workplaces and indoor environment. For the three interim targets included in 'A Safe Radiation Environment', changes are suggested for the interim targets for radioactive substances and electromagnetic fields. No change is suggested for the interim target for skin cancer

Data quality objectives lessons learned for tank waste characterization

International Nuclear Information System (INIS)

Eberlein, S.J.

1996-01-01

The tank waste characterization process is an integral part of the overall effort to control the hazards associated with radioactive wastes stored in underground tanks at the Hanford Reservation. The programs involved in the characterization of the wastes are employing Data Quality Objective (DQO) process in all information and data collection activities. The DQO process is used by the programs to address an issue or problem rather than a specific sampling event. Practical limits do not always allow for precise characterization of a tank or the implementation of the DQO process. Because of the flexibility of the DQO process, it can be used as a tool for sampling and analysis of the underground waste storage tanks. The iterative nature of the DQO process allows it to be used as additional information is claimed or lessons are learned concerning an issue or problem requiring sampling and analysis of tank waste. In addition, the application of DQO process forces alternative actions to be considered when precise characterization of a tank or the full implementation of the DQO process is not practical

The scope of the 107-N Basin Recirculation Facility Liquid/Sediment Data Quality Objectives (DQO) exclusively involves the determination of sampling and analytical requirements during the deactivation period. The sampling requirements are primarily directed at sample characterization for comparison to decontamination and decommissioning (D and D) endpoint acceptance criteria in preparation for turnover of the facilities (listed below) to D and D organization. If determined to be waste, the sample characterization is also used for comparison with the waste acceptance criteria (WAC) of the receiving facilities for selection of the appropriate disposition. Additionally, the data generated from the characterization will be used to support the selection of available disposition options. The primary media within the scope of this DQO includes the following: Accumulated liquids and sediment contained in tanks, vessels, pump wells, sumps, associated piping, and valve pit floors; and Limited solid debris (anticipated to be discovered). Although the title of this report refers only to the 107-N Basin Recirculation Building, this DQO encompasses the following four 100-N Buildings/areas: 1310-N valve pit area inside the Radioactive Chemical Waste Treatment Pump House (silo); 1314-N Waste Pump (Overflow) Tank at the Liquid Waste Disposal Station; 105-N Lift Station pump well and valve pit areas inside the 105-N Reactor Building; and 107-N Basin Recirculation Building

The Data Quality Objectives (DQO) process provides a logical planning structure for specifying the optimal sample allocation for defensible decision making, depending on acceptable levels of decision uncertainty and anticipated sampling and measurement errors. These planning inputs must be established prior to designing the data collection activity. Application of the DQO process has traditionally been performed under the framework of Classical statistical theory; elicited decision errors have been interpreted as Classical Type I and Type II errors; mean and variance constraints have been incorporated based on historical information; and, Classical statistical testing methods have been used to determine optimal sample sizes. However, decision errors are usually stated, for dichotomous hypotheses, in terms of the probability of making a false positive or false negative decision; these probabilities, at best, relate loosely to probabilities of Classical Type I and Type II errors. Statements of Classical error types are couched in the language of the probability of rejection of hypotheses as opposed to the probability that a hypothesis is correct. Also, historical or archival data are often insufficient to adequately support prior judgments of means and variances. In many circumstances, however, expert knowledge and opinion is not only available, but is substantial. Finally, a paradigm that provides solutions for other than dichotomous decision problems offers greater diversity for solving real world problems
Assuring the Quality of Agricultural Learning Repositories: Issues for the Learning Object Metadata Creation Process of the CGIAR

Science.gov (United States)

Zschocke, Thomas; Beniest, Jan

The Consultative Group on International Agricultural Re- search (CGIAR) has established a digital repository to share its teaching and learning resources along with descriptive educational information based on the IEEE Learning Object Metadata (LOM) standard. As a critical component of any digital repository, quality metadata are critical not only to enable users to find more easily the resources they require, but also for the operation and interoperability of the repository itself. Studies show that repositories have difficulties in obtaining good quality metadata from their contributors, especially when this process involves many different stakeholders as is the case with the CGIAR as an international organization. To address this issue the CGIAR began investigating the Open ECBCheck as well as the ISO/IEC 19796-1 standard to establish quality protocols for its training. The paper highlights the implications and challenges posed by strengthening the metadata creation workflow for disseminating learning objects of the CGIAR.
A method for the evaluation of image quality according to the recognition effectiveness of objects in the optical remote sensing image using machine learning algorithm.

Full Text Available Objective and effective image quality assessment (IQA is directly related to the application of optical remote sensing images (ORSI. In this study, a new IQA method of standardizing the target object recognition rate (ORR is presented to reflect quality. First, several quality degradation treatments with high-resolution ORSIs are implemented to model the ORSIs obtained in different imaging conditions; then, a machine learning algorithm is adopted for recognition experiments on a chosen target object to obtain ORRs; finally, a comparison with commonly used IQA indicators was performed to reveal their applicability and limitations. The results showed that the ORR of the original ORSI was calculated to be up to 81.95%, whereas the ORR ratios of the quality-degraded images to the original images were 65.52%, 64.58%, 71.21%, and 73.11%. The results show that these data can more accurately reflect the advantages and disadvantages of different images in object identification and information extraction when compared with conventional digital image assessment indexes. By recognizing the difference in image quality from the application effect perspective, using a machine learning algorithm to extract regional gray scale features of typical objects in the image for analysis, and quantitatively assessing quality of ORSI according to the difference, this method provides a new approach for objective ORSI assessment.

In this study, a new IQA method of standardizing the target object recognition rate (ORR) is presented to reflect quality. First, several quality degradation treatments with high-resolution ORSIs are implemented to model the ORSIs obtained in different imaging conditions; then, a machine learning algorithm is adopted for recognition experiments on a chosen target object to obtain ORRs; finally, a comparison with commonly used IQA indicators was performed to reveal their applicability and limitations. The results showed that the ORR of the original ORSI was calculated to be up to 81.95%, whereas the ORR ratios of the quality-degraded images to the original images were 65.52%, 64.58%, 71.21%, and 73.11%. The results show that these data can more accurately reflect the advantages and disadvantages of different images in object identification and information extraction when compared with conventional digital image assessment indexes. By recognizing the difference in image quality from the application effect perspective, using a machine learning algorithm to extract regional gray scale features of typical objects in the image for analysis, and quantitatively assessing quality of ORSI according to the difference, this method provides a new approach for objective ORSI assessment.

Marital quality and social support satisfaction were tested as moderators of the association between maternal depressive symptoms and parenting during early childhood (18-36 months) among 2 large, divergent, longitudinal samples (n = 526; n = 570). Unexpectedly, in both samples the association between maternal depressive symptoms and reduced parenting quality was strongest in the context of high marital quality and high social support, and largely nonsignificant in the context of low marital quality and low social support. Possible explanations for these surprising findings are discussed. Results point to the importance of accounting for factors in the broader family context in predicting the association between depressive symptoms and maternal parenting.

Tapiovaara, M

2003-01-01

The report describes FluoroQuality, a computer program that is developed in STUK and used for measuring the image quality in medical fluoroscopic equipment. The method is based on the statistical decision theory (SDT) and the main measurement result is given in terms of the accumulation rate of the signal-to-noise ratio squared (SNR sup 2 sub r sub a sub t sub e). In addition to this quantity several other quantities are measured. These quantities include the SNR of single image frames, the spatio-temporal noise power spectrum and the temporal lag. The measurement method can be used, for example, for specifying the image quality in fluoroscopic images, for optimising the image quality and dose rate in fluoroscopy and for quality control of fluoroscopic equipment. The theory behind the measurement method is reviewed and the measurement of the various quantities is explained. An example of using the method for optimising a specified fluoroscopic procedure is given. The User's Manual of the program is included a...

Poor survival rates after cardiac arrest can partly be explained by poor basic life support skills in medical professionals. This study aimed to assess quality of basic life support in medical students and paramedics. We conducted a prospective observational study with 100 early medical students (group A), 100 late medical students (group B) and 100 paramedics (group C), performing a 20-minute basic life support simulation in teams of two. Average frequency and absolute number of chest compressions per minute (mean (±SD)), chest decompression (millimetres of compression remaining, mean (±SD)), hands-off-time (seconds/minute, mean (±SD)), frequency of switching positions between ventilation and chest compression (per 20 minutes) and rate of sufficient compressions (depth ≥50mm) were assessed as quality parameters of CPR. In groups A, B and C the rates of sufficiently deep chest compressions were 56%, 42% and 52%, respectively, without significant differences. Male gender and real-life CPR experience were significantly associated with deeper chest compression. Frequency and number of chest compressions were within recommended goals in at least 96% of all groups. Remaining chest compressions were 6 mm (±2), 6 mm (±2) and 5 mm (±2) with a significant difference between group A and C (p=0.017). Hands-off times were 6s/min (±1), 5s/min (±1) and 4s/min (±1), which was significantly different across all three groups. Overall, paramedics tended to show better quality of CPR compared to medical students. Though, chest compression depth as an important quality characteristic of CPR was insufficient in almost 50% of participants, even in well trained paramedics. Therefore, we suggest that an effort should be made to find better ways to educate health care professionals in BLS.

In the present paper, author proposes the application of Support Vector Machine (SVM) for the analysis of satellite imagery. One of the advantages of SVM is that, with limited training data, it may generate comparable or even better results than the other methods. The SVM algorithm is used for automated object detection and characterization. Specifically, the SVM is applied in its basic nature as a binary classifier where it classifies two classes namely, object and background. The algorithm aims at effectively detecting an object from its background with the minimum training data. The synthetic image containing noises is used for algorithm testing. Furthermore, it is implemented to perform remote sensing image analysis such as identification of Island vegetation, water body, and oil spill from the satellite imagery. It is indicated that SVM provides the fast and accurate analysis with the acceptable result

Assessing the quality of pearls involves the use of various tools and methods, which are mainly visual and often quite subjective. Pearls are normally classified by origin and are then graded by luster, nacre thickness, surface quality, size, color and shape. The aim of this study was to investigate the capacity of Artificial Neural Networks (ANNs) to classify and estimate the quality of 27 different pearls from their UV-Visible spectra. Due to the opaque nature of pearls, spectroscopy measurements were performed using the Diffuse Reflectance UV-Visible spectroscopy technique. The spectra were acquired at two different locations on each pearl sample in order to assess surface homogeneity. The spectral data (inputs) were smoothed to reduce the noise, fed into ANNs and correlated to the pearl's quality/grading criteria (outputs). The developed ANNs were successful in predicting pearl type, mollusk growing species, possible luster and color enhancing, donor condition/type, recipient/host color, donor color, pearl luster, pearl color, origin. The results of this study shows that the developed UV-Vis spectroscopy-ANN method could be used as a more objective method of assessing pearl quality (grading) and may become a valuable tool for the pearl grading industry.

A number of theoretical models can be applied to help guide quality improvement and patient safety interventions in hospitals. However there are often significant differences between such models and, therefore, their potential contribution when applied in diverse contexts. The aim of this paper is to explore how two such models have been applied by hospitals to improve quality and safety. We describe and compare the models: (1) The Organizing for Quality (OQ) model, and (2) the Design for Integrated Safety Culture (DISC) model. We analyze the theoretical foundations of the models, and show, by using a retrospective comparative case study approach from two European hospitals, how these models have been applied to improve quality and safety. The analysis shows that differences appear in the theoretical foundations, practical approaches and applications of the models. Nevertheless, the case studies indicate that the choice between the OQ and DISC models is of less importance for guiding the practice of quality and safety improvement work, as they are both systemic and share some important characteristics. The main contribution of the models lay in their role as boundary objects directing attention towards organizational and systems thinking, culture, and collaboration

A significant number of rural Chinese men are facing difficulties in finding a spouse and may fail to ever marry due to a relative scarcity of women in the adult population. Research has indicated that marriage squeeze is a stressful event which is harmful to men's quality of life, and also weakens their social support networks. Using data collected in rural Chaohu city, Anhui, China, this study explores the effects of social support networks on quality of life of rural men who experience a marriage squeeze. The results indicate that the size of social contact networks is directly and positively associated with the quality of life of marriage-squeezed men, and moderate the negative effect of age on quality of life. Having no or limited instrumental support network and social contact network are double-edged swords, which have direct negative associations with the quality of life of marriage-squeezed men, and have moderate effects on the relationship between marriage squeeze and quality of life.

This paper describes the role of the quality assurance liaison, the responsibilities of this position, and the evolutionary changes in duties over the last six years. The role of the quality assurance liaison has had a very positive impact on the Los Alamos Yucca Mountain Site Characterization (YW) quality assurance program. Having both technical and quality assurance expertise, the quality assurance liaisons are able to facilitate communications with scientists on quality assurance issues and requirements, thereby generating greater productivity in scientific investigations. The quality assurance liaisons help ensure that the scientific community knows and implements existing requirements, is aware of new or changing regulations, and is able to conduct scientific work within Project requirements. The influence of the role of the quality assurance liaison can be measured by an overall improvement in attitude of the staff regarding quality assurance requirements and improved job performance, as well as a decrease in deficiencies identified during both internal and external audits and surveillances. This has resulted in a more effective implementation of quality assurance requirements

The objectives of this study were to: (1) describe the quantity and quality of social support networks of Latino immigrants living in a new receiving environment, and (2) determine the role such networks play in their HIV/STI risk behaviors, including substance use. Double incentivized convenience sampling was used to collect egocentric social support network data on 144 Latino immigrants. Latent class analysis was used for data reduction and to identify items best suited to measure quality and quantity of social support. Moderate and high quantity and quality of social support were protective of HIV/STI sexual risk behavior compared to low quantity and quality of support, after adjustment for gender, years in New Orleans and residing with family. Neither measure of social support was associated with binge drinking. The findings suggest that increased quantity and quality of social support decrease HIV/STI sexual risk behaviors but do not influence binge drinking. Interventions that improve the quantity and quality of social support are needed for Latino immigrants.

The New Mexico Air Quality Mapper (NMAQM) is a Web-based, open source GIS prototype application that Earth Data Analysis Center is developing under a NASA Cooperative Agreement. NMAQM enhances and extends existing data and imagery delivery systems with an existing Public Health system called the Rapid Syndrome Validation Project (RSVP). RSVP is a decision support system operating in several medical and public health arenas. It is evolving to ingest remote sensing data as input to provide early warning of human health threats, especially those related to anthropogenic atmospheric pollutants and airborne pathogens. The NMAQM project applies measurements of these atmospheric pollutants, derived from both remotely sensed data as well as from in-situ air quality networks, to both forecasting and retrospective analyses that influence human respiratory health. NMAQM provides a user-friendly interface for visualizing and interpreting environmentally-linked epidemiological phenomena. The results, and the systems made to provide the information, will be applicable not only to decision-makers in the public health realm, but also to air quality organizations, demographers, community planners, and other professionals in information technology, and social and engineering sciences. As an accessible and interactive mapping and analysis application, it allows environment and health personnel to study historic data for hypothesis generation and trend analysis, and then, potentially, to predict air quality conditions from daily data acquisitions. Additional spin off benefits to such users include the identification of gaps in the distribution of in-situ monitoring stations, the dissemination of air quality data to the public, and the discrimination of local vs. more regional sources of air pollutants that may bear on decisions relating to public health and public policy.

Full Text Available Wireless-VoIP communications introduce perceptual degradations that are not present with traditional VoIP communications. This paper investigates the effects of such degradations on the performance of three state-of-the-art standard objective quality measurement algorithms—PESQ, P.563, and an "extended" E-model. The comparative study suggests that measurement performance is significantly affected by acoustic background noise type and level as well as speech codec and packet loss concealment strategy. On our data, PESQ attains superior overall performance and P.563 and E-model attain comparable performance figures.

Improvement of quality of life has been one of goals in health care for people living with bladder cancer. Meanwhile, positive psycho-social variables in oncology field have increasingly received attention. However, the assessment of quality of life of bladder cancer patients and the integrative effects of positive psycho-social variables has limited reporting. The aim of this study was to assess quality of life as well as the integrative effects of social support, hope and resilience on quality of life among Chinese bladder cancer patients. A cross-sectional study was conducted at the First Hospital of China Medical University in Liaoning Province, China. A total of 365 bladder cancer patients eligible for this study completed questionnaires on demographic variables, FACT-BL, Perceived Social Support Scale, Adult Hope Scale, and Resilience Scale-14 during July 2013 to July 2014. The average score of FACT-BL was 87.60 ± 16.27 (Mean ± SD). Hierarchical regression analyses indicated that social support, hope and resilience as a whole accounted for 30.3 % variance of quality of life. Under standardized estimate (β) sequence, social support, hope and resilience significantly and positively associated with quality of life, respectively. Quality of life for bladder cancer patients was at a low level in China, which should receive more attention in Chinese medical institutions. More importantly, efforts to increase social support, hope and resilience might be useful to support the quality of life among Chinese bladder cancer patients.

Given evidence suggesting a detrimental effect of occupational stress on sleep, it is important to identify protective factors that may ameliorate this effect. We followed 87 paramedics upon waking and after work over 1 week using a daily diary methodology. Multilevel modeling was used to examine whether the detrimental effects of daily occupational stress on sleep quality were buffered by perceived social support availability. Paramedics who reported more support availability tended to report better quality sleep over the week. Additionally, perceived support availability buffered postworkday sleep from average occupational stress and days of especially high occupational stress. Perceived support availability also buffered off-workday sleep from the cumulative amount of occupational stress experienced over the previous workweek. Those with low levels of support displayed poor sleep quality in the face of high occupational stress; those high in support did not show significant effects of occupational stress on sleep.

The purpose of the present study is to measure the effectiveness of two treatment techniques--vocalization with abdominal breath support and manual circumlaryngeal therapy (MCT)--in patients with muscle tension dysphonia (MTD). The vocal quality before and after the two treatment techniques was measured by means of the dysphonia severity index (DSI), which is designed to establish an objective and quantitative correlate of the perceived vocal quality. The DSI is based on the weighted combination of the following set of voice measurements: maximum phonation time (MPT), highest frequency, lowest intensity, and jitter. The repeated-measures analysis of variance (ANOVA) revealed a significant difference between the objective overall vocal quality before and after MCT. No significant differences were measured between the objective overall vocal quality before and after vocalization with abdominal breath support. This study showed evidence that MCT is an effective treatment technique for patients with elevated laryngeal position, increased laryngeal muscle tension, and MTD. The precise way in which MCT has an effect on vocal quality has not been addressed in this experiment, but merits study. Further research into this topic could focus on electromyography (EMG) recordings in relation to vocal improvements with larger sample of subjects. (c) 2010 The Voice Foundation.

Technology-delivered interventions addressing a broad range of problems for which clients present for therapy are proliferating. However, little is known of leadership dynamics that emerge in online group interventions. The purpose of this study was to assess the types of leadership qualities that would emerge in an online social support group intervention to improve medication adherence for men with HIV, and to characterize the demographic and psychosocial profiles of leaders. Written posts ( n =616) from 66 men were coded using an adapted version of the Full Range Model of Leadership. Results showed that 10% ( n =64) of posts reflected one of five leadership types, the most common of which was mentoring/providing feedback (40% of leadership posts). The next most common leadership style were instances in which encouragement was offered (30% of leadership posts). Leaders appeared to have lived with HIV longer and have higher Internet knowledge scores than non-leaders. Results indicate that online group interventions potentially may be useful to supplement traditional face-to-face treatment by providing an additional venue for group members to mentor and provide emotional support to each other. However, additional research is needed to more fully understand leadership qualities and group dynamics in other online group intervention settings.

Authors may choose to work with professional medical writers when writing up their research for publication. We examined the relationship between medical writing support and the quality and timeliness of reporting of the results of randomised controlled trials (RCTs). Cross-sectional study. Primary reports of RCTs published in BioMed Central journals from 2000 to 16 July 2014, subdivided into those with medical writing support (n=110) and those without medical writing support (n=123). Proportion of items that were completely reported from a predefined subset of the Consolidated Standards of Reporting Trials (CONSORT) checklist (12 items known to be commonly poorly reported), overall acceptance time (from manuscript submission to editorial acceptance) and quality of written English as assessed by peer reviewers. The effect of funding source and publication year was examined. The number of articles that completely reported at least 50% of the CONSORT items assessed was higher for those with declared medical writing support (39.1% (43/110 articles); 95% CI 29.9% to 48.9%) than for those without (21.1% (26/123 articles); 95% CI 14.3% to 29.4%). Articles with declared medical writing support were more likely than articles without such support to have acceptable written English (81.1% (43/53 articles); 95% CI 67.6% to 90.1% vs 47.9% (23/48 articles); 95% CI 33.5% to 62.7%). The median time of overall acceptance was longer for articles with declared medical writing support than for those without (167 days (IQR 114.5-231 days) vs 136 days (IQR 77-193 days)). In this sample of open-access journals, declared professional medical writing support was associated with more complete reporting of clinical trial results and higher quality of written English. Medical writing support may play an important role in raising the quality of clinical trial reporting. Published by the BMJ Publishing Group Limited.

Data Quality Objectives For Selecting Waste Samples For Bench-Scale Reformer Treatability Studies

International Nuclear Information System (INIS)

Banning, D.L.

2011-01-01

This document describes the data quality objectives to select archived samples located at the 222-S Laboratory for Bench-Scale Reforming testing. The type, quantity, and quality of the data required to select the samples for Fluid Bed Steam Reformer testing are discussed. In order to maximize the efficiency and minimize the time to treat Hanford tank waste in the Waste Treatment and Immobilization Plant, additional treatment processes may be required. One of the potential treatment processes is the fluidized bed steam reformer. A determination of the adequacy of the fluidized bed steam reformer process to treat Hanford tank waste is required. The initial step in determining the adequacy of the fluidized bed steam reformer process is to select archived waste samples from the 222-S Laboratory that will be used in a bench scale tests. Analyses of the selected samples will be required to confirm the samples meet the shipping requirements and for comparison to the bench scale reformer (BSR) test sample selection requirements.
Ubiquitous computing to support co-located clinical teams: using the semiotics of physical objects in system design.

Bang, Magnus; Timpka, Toomas

2007-06-01

Co-located teams often use material objects to communicate messages in collaboration. Modern desktop computing systems with abstract graphical user interface (GUIs) fail to support this material dimension of inter-personal communication. The aim of this study is to investigate how tangible user interfaces can be used in computer systems to better support collaborative routines among co-located clinical teams. The semiotics of physical objects used in team collaboration was analyzed from data collected during 1 month of observations at an emergency room. The resulting set of communication patterns was used as a framework when designing an experimental system. Following the principles of augmented reality, physical objects were mapped into a physical user interface with the goal of maintaining the symbolic value of those objects. NOSTOS is an experimental ubiquitous computing environment that takes advantage of interaction devices integrated into the traditional clinical environment, including digital pens, walk-up displays, and a digital desk. The design uses familiar workplace tools to function as user interfaces to the computer in order to exploit established cognitive and collaborative routines. Paper-based tangible user interfaces and digital desks are promising technologies for co-located clinical teams. A key issue that needs to be solved before employing such solutions in practice is associated with limited feedback from the passive paper interfaces.

To explore the associations of the professional quality of life and social support with health in nurses. Physical and mental health may be associated with absence from work among nurses. Few studies have explored the associations of professional quality of life and social support on the physical and mental health of nurses. This was a cross-sectional study. In total, 294 nurses were recruited from a hospital in Southern Taiwan. A self-report questionnaire was used to collect data. Burnout, secondary traumatic stress and social support from relatives or friends were important factors of physical and mental health. Interactions between support from relatives or friends and secondary traumatic stress are important factors in physical health. Reducing burnout and secondary traumatic stress is important for physical and mental health of nurses. Increasing social support from relatives or friends may be useful to reduce the negative effects of secondary traumatic stress on the physical health of nurses. Nurse managers could design interventions to reduce and prevent nurses from being influenced by burnout and secondary traumatic stress. Educating nurses to build effective social networks with relatives or friends and to seek support when experiencing secondary traumatic stress may also be needed. © 2017 John Wiley & Sons Ltd.

The tank waste characterization process is an integral part of the overall effort to control the hazards associated with radioactive wastes stored in underground tanks at the Hanford Reservation. The programs involved in the characterization of the waste are employing the Data Quality Objective (DQO) process in all information and data collection activities. The DQO process is used by the programs to address an issue or problem rather than a specific sampling event. Practical limits (e.g., limited number and location of sampling points) do not always allow for precise characterization of a tank or the full implementation of the DQO process. Because of the flexibility of the DQO process, it can be used as a planning tool for sampling and analysis of the underground waste storage tanks. The iterative nature of the DQO process allows it to be used as additional information is obtained or open-quotes lessons are learnedclose quotes concerning an issue or problem requiring sampling and analysis of tank waste. In addition, the application of the DQO process forces alternative actions to be considered when precise characterization of a tank or the fall implementation of the DQO process is not practical

Data from 42 heterosexual, 46 gay male, and 33 lesbian couples were used to assess the contribution of conflict and support discussions to relationship quality. Couples completed questionnaires, and videotaped discussions were coded for levels of negative and positive behaviors. Correlations showed that behaviors were associated with relationship quality in the expected directions. Hierarchical linear modeling analyses assessed the unique contributions of individual and dyadic behaviors to the variability of relationship quality. The findings indicated that, beyond the contribution of individual negative behaviors in the conflict task, the variables of dyadic positive behaviors in the conflict task, individual positive behaviors in the support task, and perceived help accounted for unexplained variance in relationship quality. There were no differences between types of couples on levels of behaviors or on their contributions to relationship quality.

The rate of heat generation for tank 241-C-106 at the Hanford Site is estimated at more then 100,000 Btu/h. The heat is generated primarily from the radioactive decay of 90 Sr waste that was inadvertently transferred into the tank in the late 1960s. If proper tank cooling is not maintained for this tank, heat-induced structural damage to the tank's concrete shell could result in the release of nuclear waste to the environment. Because of high-heat concerns in January 1991, tank 241-C-106 was designated as a Watch List tank and deemed as a Priority 1 safety issue. Waste Tank Safety Program (WTSP) is responsible for the resolution of this safety issue. Although forced cooling is effective for short term, the long-term resolution for tank cooling is waste retrieval. Single-shell Tank Retrieval Project (Retrieval) is responsible for the safe retrieval and transfer of radioactive waste from tank 241-C-106 to a selected double-shell tank. This data quality objective (DQO) study is an effort to determine engineering and design data needs for WTSP and assist Retrieval in designing contingency action retrieval systems. The 7-step DQO process is a tool developed by the Environmental Protection Agency with a goal of identifying needs and reducing costs. This report discusses the results of two DQO efforts for WTSP and Retrieval. The key data needs to support WTSP are thermal conductivity, permeability, and heat load profile. For the Retrieval support, there are nine and three data needs identified, respectively, for retrieval engineering system design and HVAC system design. The updated schedule to drill two core samples using rotary mode is set for March 1994. The analysis of the sample is expected to be completed by September 1994

This document describes the results of the data quality objective (DQO) process undertaken to define data needs for state and federal requirements associated with toxic, hazardous, and/or radiological air emissions under the jurisdiction of the River Protection Project (RPP). Hereafter, this document is referred to as the Air DQO. The primary drivers for characterization under this DQO are the regulatory requirements pursuant to Washington State regulations, that may require sampling and analysis. The federal regulations concerning air emissions are incorporated into the Washington State regulations. Data needs exist for nonradioactive and radioactive waste constituents and characteristics as identified through the DQO process described in this document. The purpose is to identify current data needs for complying with regulatory drivers for the measurement of air emissions from RPP facilities in support of air permitting. These drivers include best management practices; similar analyses may have more than one regulatory driver. This document should not be used for determining overall compliance with regulations because the regulations are in constant change, and this document may not reflect the latest regulatory requirements. Regulatory requirements are also expected to change as various permits are issued. Data needs require samples for both radionuclides and nonradionuclide analytes of air emissions from tanks and stored waste containers. The collection of data is to support environmental permitting and compliance, not for health and safety issues. This document does not address health or safety regulations or requirements (those of the Occupational Safety and Health Administration or the National Institute of Occupational Safety and Health) or continuous emission monitoring systems. This DQO is applicable to all equipment, facilities, and operations under the jurisdiction of RPP that emit or have the potential to emit regulated air pollutants.

This mixed-method study focused on new graduate nurses and their transition to practice. Transition to practice can be a time of heightened stress and anxiety, leaving many new graduates disillusioned and dissatisfied with their work. The study explored how satisfaction levels with transition may improve during their first year, using a unique approach of a continuous quality assurance feedback loop. This assurance framework is utilised in hospitality, automotive and supply chain logistics and in health, primarily to monitor patient outcomes. However, an association with graduate nurse satisfaction has not been previously reported. Graduate nurses from two health services completed a short survey questionnaire every four weeks for 12 months. De-identified aggregated data was sent to health service management, giving them an opportunity to integrate the findings with the objective of potentially increasing graduate satisfaction ratings. Quantitative findings showed no statistical significance of graduate nurse satisfaction scores between health services, however, one health service consistently outperformed the other. Qualitative findings drawn from a seminar and interviews confirmed that one health service took a more proactive stance with the monthly reports, communicating the results to ward managers. Outcomes reflected a greater commitment of support and an overall increase of satisfaction scores. Copyright © 2017 Elsevier Ltd. All rights reserved.

Although sleep alterations can be an important factor contributing to the clinical state of Systemic Lupus Erythematosus, there are no studies to adequately assess sleep quality in this type of disease. The aim of this work is to analyse the sleep quality of Systemic Lupus Erythematous (SLE) patients based on more objective information provided by actigraphy and mobile systems. The idea is to carry out a comprehensive study by analysing how environmental conditions and factors can affect sleep quality. In traditional methods the information for assessing sleep quality is obtained through questionnaires. In this work, a novel method is proposed by combining these questionnaires that provide valuable but subjective information with actigraphy and a mobile system to collect more objective information about the patient and their environment. The method provides mechanisms to detect how sleep hygiene could be associated directly with the sleep quality of the subjects, in order to provide a custom intervention to SLE patients. Moreover, this alternative provides ease of use, and non-intrusive ICT (Information and Communication Technology) through a wristband and a mHealth system. The mHealth system has been developed for environmental conditions sensing. This consists of a mobile device with built-in sensors providing input data about the bedroom environment during sleep, and a set of services of the Environmental Monitoring System for properly managing the configuration, registration and fusion of those input data. In previous studies, this information has never been taken into account. However, the information could be relevant in the case of SLE patients. The sample is composed of 9 women with SLE and 11 matched controls with a mean age of 35.78 and 32.18, respectively. Demographic and clinical variables between SLE patients and healthy controls are compared using the Fisher exact test and the Mann-Whitney U test. Relationships between psychological variables

Seafarers have reported impaired health and health-related quality of life (HRQOL). Social support might increase HRQOL, but little is known about this association among Chinese seafarers. The aim of this study was to describe social support and explore its association with HRQOL among Chinese seafarers. A cross-sectional survey was conducted in the ports of Nantong and Rugao, China, from April to December 2013. A total of 917 Chinese seafarers were interviewed on social support, mental distress, perceived occupational stress, and HRQOL using the following self-administered questionnaires: The Social Support Rating Scale, Self-rating Depression Scale, Occupational Stress Questionnaire, and the World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaire. Hierarchical linear regression modelling was used to analyze the association between seafarers' subjective level of social support and their HRQOL. Of the 917 male Chinese seafarers included in the study, 40.7% perceived high levels of social support, and 39.1% were highly satisfied with their overall quality of life (QOL). Hierarchical regression analysis showed significant associations between level of social support and all health dimensions in the WHOQOL-BREF, even after adjusting for depressive symptoms, occupational stress, occupational activities, sleep duration, and other relevant covariates. Compared with the medium or low level social support group, seafarers with a high level of social support had better QOL scores in the general facet health and QOL (β = 2.43, phealth (β = 3.23, phealth (β = 5.56, psocial relation (β = 6.07, psocial support has a significant positive effect on their HRQOL. Efforts to improve social support should be undertaken.

Full Text Available The main topic of this article is based on the fact that environmental education and edification have got an irreplaceable and preferred position within the framework of a sustainable socio-economic development. Environmental education, which is performed at technical universities, has to offer professional and methodical knowledge concerning questions of environment for students of various technical branches. This education is performed in such way that the graduates, after entering the practical professional life, will be able to participate in solutions to the new actual problems that are related to environment and its protection, as well. Nowadays, during the educational proces it is also necessary to introduce technical development in a more extended rate. Taking into consideration the above-mentioned facts it is possible to say that the educational support for environmental studies is a relevant aspect, which should be integrated into the university educational process. It is a positive development trend that greater emphasis is focused on the quality of university education for the environmental engineers. Our society requires an increasing number of environmentally educated engineers who are able to participate in qualitative academic preparation, i.e. the so-called environmentalists. But the worldwide phenomena of technical development and globalisation also pose high claims for quality of their preparations including devices and computers skills. The Department of Process and Environmental Engineering at the Faculty of Mechanical Engineering, Technical University in Košice, the Slovak Republic is the institution specified and intended for quality optimisation. This Department introduced into the study programmes (“Environmental Management” and “Technology of Environmental Protection” study subjects with software support, which are oriented towards the indoor and outdoor environment and in this way the Department of Process and
Description and status update on GELLO: a proposed standardized object-oriented expression language for clinical decision support.

A major obstacle to sharing computable clinical knowledge is the lack of a common language for specifying expressions and criteria. Such a language could be used to specify decision criteria, formulae, and constraints on data and action. Al-though the Arden Syntax addresses this problem for clinical rules, its generalization to HL7's object-oriented data model is limited. The GELLO Expression language is an object-oriented language used for expressing logical conditions and computations in the GLIF3 (GuideLine Interchange Format, v. 3) guideline modeling language. It has been further developed under the auspices of the HL7 Clinical Decision Support Technical Committee, as a proposed HL7 standard., GELLO is based on the Object Constraint Language (OCL), because it is vendor-independent, object-oriented, and side-effect-free. GELLO expects an object-oriented data model. Although choice of model is arbitrary, standardization is facilitated by ensuring that the data model is compatible with the HL7 Reference Information Model (RIM).

Wilson, Lauren Elizabeth; Gahan, Michelle Elizabeth; Robertson, James; Lennard, Chris

2018-03-01

In a previous publication we described a systems approach to forensic science applied in the military domain. The forensic science 'system of systems' describes forensic science as a sub-system in the larger criminal justice, law enforcement, intelligence, and military systems, with quality management being an important supporting system. Quality management systems help to ensure that organisations achieve their objective and continually improve their capability. Components of forensic science quality management systems can include standardisation of processes, accreditation of facilities to national/international standards, and certification of personnel. A fit for purpose quality management system should be balanced to allow organisations to meet objectives, provide continuous improvement; mitigate risk; and impart a positive quality culture. Considerable attention over the last decades has been given to the need for forensic science quality management systems to meet criminal justice and law enforcement objectives. More recently, the need for the forensic quality management systems to meet forensic intelligence objectives has been considered. This paper, for the first time, discusses the need for a fit for purpose quality management system for military forensic exploitation. Crown Copyright © 2018. Published by Elsevier B.V.

Denis, E.

2008-04-01

This work presents the conception and implementation of new automatic and quantitative quality assessment methods for geometric treatment planning in external radiotherapy. Treatment planning Systems (T.P.S.) quality control is mandatory in France and in the world because of encountered risks but the physical tools recommended to lead this quality control are not adapted to the situation. We present a new methodology for control quality based on the definition of Digital Test Objects (D.T.O.) that are directly introduced in the T.P.S. without acquisition device. These D.T.O. are consistently defined in a continuous and discrete modes. The T.P.S. responses to input D.T.O. are compared to theoretical results thanks to figures of merit specifically designed for each elementary control. The tests we carried out during this study allow to validate our solutions for the quality assessment of the auto-contouring, auto-margining, isocenter computation, collimator conformation and digitally reconstructed radiograph generation tools, as well as our solutions for marker positioning, collimator and displayed bean rotation, incidence, divergence and dimensions. Quality assessment solutions we propose are then fast and effective (no acquisition by the device, reduced manipulations), and more precise thanks to the continuous-discrete equivalence realized at the beginning of the modelling

Data quality objectives for the 100-D Group 2 waste sites

International Nuclear Information System (INIS)

1996-08-01

The 100-D Area contains 10 past-practice, liquid waste disposal sites associated with two plutonium-production nuclear reactors that operated from 1944 to 1965. It is estimated that 134,000 loose cubic meters of soil and structural debris are contaminated with various radionuclides and metals. The 100-Area interim record of decision specified that the waste sites were to be remediated to the extent practicable to protect human health and the environment, and to allow unrestricted future use of the area. The Data Quality Objective process for the 100-D Area waste sites is a US Environmental Protection Agency-required approach to planning and coordinating data acquisition. This process is also used as a decision-making tool to assess the use of historical or previously acquired data and establishes interfaces and promotes communication with key decision makers and other stakeholders
Intelligent Quality Prediction Using Weighted Least Square Support Vector Regression

Science.gov (United States)

Yu, Yaojun

A novel quality prediction method with mobile time window is proposed for small-batch producing process based on weighted least squares support vector regression (LS-SVR). The design steps and learning algorithm are also addressed. In the method, weighted LS-SVR is taken as the intelligent kernel, with which the small-batch learning is solved well and the nearer sample is set a larger weight, while the farther is set the smaller weight in the history data. A typical machining process of cutting bearing outer race is carried out and the real measured data are used to contrast experiment. The experimental results demonstrate that the prediction accuracy of the weighted LS-SVR based model is only 20%-30% that of the standard LS-SVR based one in the same condition. It provides a better candidate for quality prediction of small-batch producing process.
Research on knowledge support technology for product innovation design based on quality function knowledge deployment

Directory of Open Access Journals (Sweden)

Kai Zhang

2016-06-01

Full Text Available Based on the analysis of the relationship between the process of product innovation design and knowledge, this article proposes a theoretical model of quality function knowledge deployment. In order to link up the product innovation design and the knowledge required by the designer, the iterative method of quality function knowledge deployment is refined, as well as the knowledge retrieval model and knowledge support model based on quality function knowledge deployment are established. In the whole life cycle of product design, in view of the different requirements for knowledge in conceptual design stage, components’ configuration stage, process planning stage, and production planning stage, the quality function knowledge deployment model could link up the required knowledge with the engineering characteristics, component characteristics, process characteristics, and production characteristics in the four stages using the mapping relationship between the function characteristics and the knowledge and help the designer to track the required knowledge for realizing product innovation design. In this article, an instance about rewinding machine is given to demonstrate the practicability and validity of product innovation design knowledge support technology based on quality function knowledge deployment.

This cross-sectional study evaluated lifetime prevalence of suicide attempts in 170 HIV/AIDS patients with substance use disorders and the impact of suicide attempt history on subjective indices of quality of life and objective indices of cognitive and physical functioning. All patients met the diagnostic criteria for past-year cocaine or opioid use disorders and 27% of patients also had co-occurring alcohol use disorders. Compared to their counterparts without a history of a suicide attempt, patients with a history of a suicide attempt (n = 60, 35.3%) had significantly poorer emotional and cognitive quality of life scores (ps quality-of-life scores. Lifetime suicide attempt status was unrelated to objective indices of cognitive functioning, but there was a non-significant trend (p = .07) toward lower viral loads in those with a lifetime suicide attempt relative to those without. The findings indicate that suicide attempt histories are prevalent among HIV/AIDS patients with substance use disorders and relate to poorer perceived emotional and cognitive quality of life, but not objective functioning. HIV/AIDS patients with substance use disorders should be screened for lifetime histories of suicide attempts and offered assistance to improve perceived emotional and cognitive functioning. © The Author(s) 2016.

Although the patient-centered medical home endorses quality improvement principles, methods for supporting ongoing, systematic primary care quality improvement have not been evaluated. We introduced primary care quality councils at six Veterans Health Administration sites as an organizational intervention with three key design elements: (a) fostering interdisciplinary quality improvement leadership, (b) establishing a structured quality improvement process, and (c) facilitating organizationally aligned frontline quality improvement innovation. Our evaluation objectives were to (a) assess design element implementation, (b) describe implementation barriers and facilitators, and (c) assess successful quality improvement project completion and spread. We analyzed administrative records and conducted interviews with 85 organizational leaders. We developed and applied criteria for assessing design element implementation using hybrid deductive/inductive analytic techniques. All quality councils implemented interdisciplinary leadership and a structured quality improvement process, and all but one completed at least one quality improvement project and a toolkit for spreading improvements. Quality councils were perceived as most effective when service line leaders had well-functioning interdisciplinary communication. Matching positions within leadership hierarchies with appropriate supportive roles facilitated frontline quality improvement efforts. Two key resources were (a) a dedicated internal facilitator with project management, data collection, and presentation skills and (b) support for preparing customized data reports for identifying and addressing practice level quality issues. Overall, quality councils successfully cultivated interdisciplinary, multilevel primary care quality improvement leadership with accountability mechanisms and generated frontline innovations suitable for spread.

A Psychoacoustic-Based Multiple Audio Object Coding Approach via Intra-Object Sparsity

Directory of Open Access Journals (Sweden)

Maoshen Jia

2017-12-01

Full Text Available Rendering spatial sound scenes via audio objects has become popular in recent years, since it can provide more flexibility for different auditory scenarios, such as 3D movies, spatial audio communication and virtual classrooms. To facilitate high-quality bitrate-efficient distribution for spatial audio objects, an encoding scheme based on intra-object sparsity (approximate k-sparsity of the audio object itself is proposed in this paper. The statistical analysis is presented to validate the notion that the audio object has a stronger sparseness in the Modified Discrete Cosine Transform (MDCT domain than in the Short Time Fourier Transform (STFT domain. By exploiting intra-object sparsity in the MDCT domain, multiple simultaneously occurring audio objects are compressed into a mono downmix signal with side information. To ensure a balanced perception quality of audio objects, a Psychoacoustic-based time-frequency instants sorting algorithm and an energy equalized Number of Preserved Time-Frequency Bins (NPTF allocation strategy are proposed, which are employed in the underlying compression framework. The downmix signal can be further encoded via Scalar Quantized Vector Huffman Coding (SQVH technique at a desirable bitrate, and the side information is transmitted in a lossless manner. Both objective and subjective evaluations show that the proposed encoding scheme outperforms the Sparsity Analysis (SPA approach and Spatial Audio Object Coding (SAOC in cases where eight objects were jointly encoded.

Quality inspection guided laser processing of irregular shape objects by stereo vision measurement: application in badminton shuttle manufacturing

Science.gov (United States)

Qi, Li; Wang, Shun; Zhang, Yixin; Sun, Yingying; Zhang, Xuping

2015-11-01

The quality inspection process is usually carried out after first processing of the raw materials such as cutting and milling. This is because the parts of the materials to be used are unidentified until they have been trimmed. If the quality of the material is assessed before the laser process, then the energy and efforts wasted on defected materials can be saved. We proposed a new production scheme that can achieve quantitative quality inspection prior to primitive laser cutting by means of three-dimensional (3-D) vision measurement. First, the 3-D model of the object is reconstructed by the stereo cameras, from which the spatial cutting path is derived. Second, collaborating with another rear camera, the 3-D cutting path is reprojected to both the frontal and rear views of the object and thus generates the regions-of-interest (ROIs) for surface defect analysis. An accurate visual guided laser process and reprojection-based ROI segmentation are enabled by a global-optimization-based trinocular calibration method. The prototype system was built and tested with the processing of raw duck feathers for high-quality badminton shuttle manufacture. Incorporating with a two-dimensional wavelet-decomposition-based defect analysis algorithm, both the geometrical and appearance features of the raw feathers are quantified before they are cut into small patches, which result in fully automatic feather cutting and sorting.

Identifying modifiable correlates of good quality of life in adults with autism spectrum disorder is of paramount importance for intervention development as the population of adults with autism spectrum disorder increases. This study sought to examine social support and perceived stress as potential modifiable correlates of quality of life in adults with autism spectrum disorder. We hypothesized that adults with autism spectrum disorder without co-occurring intellectual disabilities ( N = 40; aged 18-44 years) would report lower levels of social support and quality of life than typical community volunteers who were matched for age, sex, and race ( N = 25). We additionally hypothesized that social support would buffer the effect of perceived stress on quality of life in adults with autism spectrum disorder. Results indicated that adults with autism spectrum disorder reported significantly lower levels of social support and quality of life than matched typical community volunteers. In addition, findings showed significant direct effects of social support and perceived stress on quality of life in adults with autism spectrum disorder. Social support did not buffer the effect of perceived stress on quality of life. Interventions that teach adults with autism spectrum disorder skills to help them better manage stress and cultivate supportive social relationships have the potential to improve quality of life.
Educational Rationale Metadata for Learning Objects

Full Text Available Instructors searching for learning objects in online repositories will be guided in their choices by the content of the object, the characteristics of the learners addressed, and the learning process embodied in the object. We report here on a feasibility study for metadata to record process-oriented information about instructional approaches for learning objects, though a set of Educational Rationale [ER] tags which would allow authors to describe the critical elements in their design intent. The prototype ER tags describe activities which have been demonstrated to be of value in learning, and authors select the activities whose support was critical in their design decisions. The prototype ER tag set consists descriptors of the instructional approach used in the design, plus optional sub-elements for Comments, Importance and Features which implement the design intent. The tag set was tested by creators of four learning object modules, three intended for post-secondary learners and one for K-12 students and their families. In each case the creators reported that the ER tag set allowed them to express succinctly the key instructional approaches embedded in their designs. These results confirmed the overall feasibility of the ER tag approach as a means of capturing design intent from creators of learning objects. Much work remains to be done before a usable ER tag set could be specified, including evaluating the impact of ER tags during design to improve instructional quality of learning objects.

The previous studies reported Type D was associated with poor quality of life (QoL), increased psychological distress, and impaired health status in cardiac patients. The aim of this study is to assess the relationships among Type D personality, illness perception, social support, and investigate the impact of Type D personality on QoL in continuous ambulatory peritoneal dialysis (CAPD) patients. Type D personality was assessed by the Chinese 14-item Type D Personality Scale (DS14). Illness perceptions were assessed using the Chinese version of the Brief Illness Perception Questionnaire (B-IPQ). Social support status was assessed by the well-validated social support rating scale (SSRS). Patients' QoL was assessed by using Medical Outcomes Short Form 36 (SF-36), respectively. The Type Ds had significantly lower objective support score (8.18 ± 2.56 vs. 9.67 ± 3.28, p = 0.0001), subjective support score (6.71 ± 2.0 vs. 7.62 ± 1.93, p = 0.0001) and utilization of social support score (6.76 ± 2.0 vs. 7.61 ± 1.94, p = 0.0001) than that of the non-type Ds. Type Ds believed their illness had much more serious consequences (7.67 ± 2.64 vs. 6.27 ± 3.45, p illness (6.65 ± 2.54 vs. 7.31 ± 2.36, p = 0.023). Significant differences were found between Type Ds and non-Type Ds in PCS (40.53 ± 6.42 vs. 48.54 ± 6.21 p mental component score (MCS) (r = -0.31, p social support (r = -0.24, p illness perceptions, social support and QoL in CAPD patients. The worse illness perceptions and lower social support level therefore represent possible mechanisms to explain the link between Type D and poor QoL in CAPD patients.

Full Text Available The concept of quality improvement in industry has originated from the involvement of inspector which has become the most important part of manufacturing process or development activity. Over years, this initiative is migrated to various support functions of the industry. In this paper, emphasis has been given particularly in the areas related to support functions where improvement project s can be effectively done and hence organization wide impact is assessed. Two case studies are presented here in this context. The first study shows how smaller change in content structure and delivery met hod can drastically improve the training feedback and the second one demonstrates minimizing lead time to recruitment with a cost-effective process modification.

To identify and describe: (1) characteristics of sleep quality, daytime sleepiness, and quality of life (QOL) pre and post implantation of a left ventricular assist device (LVAD); (2) changes in sleep quality, daytime sleepiness, and QOL at baseline and 6 months post implant; and (3) relationships among the sleep quality, daytime sleepiness, and QOL variables. We employed an exploratory research design. Fifteen patients with continuous/non-pulsatile flow LVAD consented to partake in the study. However, only 12 patients completed the baseline and 6-month post-LVAD implant data. We used the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) to measure study variables. Data were analyzed using IBM SPSS 19.0 software. Patients reported worse sleep quality accompanied by daytime sleepiness particularly at baseline, and persisting up to 6 months post LVAD implant. A significant improvement in QOL was observed at 6 months post implant, but remained at poor levels. Correlations among sleep disturbance and daytime dysfunction components of PSQI and global daytime sleepiness (ESS) with QOL were strong (Pearson's correlations r >.60; p values sleep quality, daytime sleepiness, and QOL in patients with LVADs. Our findings offer beginning evidence about the sleep-QOL connection in this population which warrants attention in clinical practice and research. Further research is required to clearly elucidate these phenomena in patients with mechanical circulatory support and other implantable artificial organs.

Purpose We examined mechanisms through which social relationships influence quality of life (QOL) in breast cancer survivors. Methods This study included 3,139 women from the Pathways Study who were diagnosed with breast cancer from 2006-2011 and provided data on social networks (presence of spouse or intimate partner, religious/social ties, volunteering, and numbers of close friends and relatives), social support (tangible, emotional/informational, affection, positive social interaction), and quality of life (QOL), measured by the FACT-B, approximately two months post-diagnosis. We used logistic models to evaluate associations between social network size, social support, and lower vs. higher than median QOL scores. We further stratified by stage at diagnosis and treatment. Results In multivariate-adjusted analyses, women who were characterized as socially isolated had significantly lower FACT-B (OR=2.18, 95%CI:1.72-2.77), physical well-being (WB) (OR=1.61, 95%CI:1.27-2.03), functional WB (OR=2.08, 95%CI:1.65-2.63), social WB (OR=3.46, 95%CI:2.73-4.39), and emotional WB (OR=1.67, 95%CI:1.33-2.11) scores and higher breast cancer symptoms (OR=1.48, 95%CI:1.18-1.87), compared with socially integrated women. Each social network member independently predicted higher QOL. Simultaneous adjustment for social networks and social support partially attenuated associations between social networks and QOL. The strongest mediator and type of social support that was most predictive of QOL outcomes was “positive social interaction”. However, each type of support was important depending on outcome, stage, and treatment status. Conclusions Larger social networks and greater social support were related to higher QOL after a diagnosis of breast cancer. Effective social support interventions need to evolve beyond social-emotional interventions and need to account for disease severity and treatment status. PMID:23657404

The primary challenge of the X-33 CAN is to build and test a prototype LO2 and LH2 densification ground support equipment (GSE) unit, and perform tank thermodynamic testing within the 15 month phase 1 period. The LO2 and LH2 propellant densification system will be scaled for the IPTD LO2 and LH2 tank configurations. The IPTD tanks were selected for the propellant technology demonstration because of the potential benefits to the phase 1 plan: tanks will be built in time to support thermodynamic testing; minimum cost; minimum schedule risk; future testing at MSFC will build on phase 1 data base; and densification system will be available to support X-33 and RLV engine test at IPTD. The objective of the task 1 effort is to define the preliminary requirements of the propellant densification GSE and tank recirculation system. The key densification system design parameters to be established in Task 1 are: recirculation flow rate; heat exchanger inlet temperature; heat exchanger outlet temperature; maximum heat rejection rate; vent flow rate (GN2 and GH2); densification time; and tank pressure level.

Purpose: To ensure patient safety and treatment quality in RT departments that use Varian ARIA and Eclipse, we developed a computer software system and interface functions that allow previously developed electron chart checking (EcCk) methodologies to support these Varian systems. Methods: ARIA and Eclipse store most patient information in its MSSQL database. We studied the contents in the hundreds database tables and identified the data elements used for patient treatment management and treatment planning. Interface functions were developed in both c-sharp and MATLAB to support data access from ARIA and Eclipse servers using SQL queries. These functions and additional data processing functions allowed the existing rules and logics from EcCk to support ARIA and Eclipse. Dose and structure information are important for plan quality check, however they are not stored in the MSSQL database but as files in Varian private formats, and cannot be processed by external programs. We have therefore implemented a service program, which uses the DB Daemon and File Daemon services on ARIA server to automatically and seamlessly retrieve dose and structure data as DICOM files. This service was designed to 1) consistently monitor the data access requests from EcCk programs, 2) translate the requests for ARIA daemon services to obtain dose and structure DICOM files, and 3) monitor the process and return the obtained DICOM files back to EcCk programs for plan quality check purposes. Results: EcCk, which was previously designed to only support MOSAIQ TMS and Pinnacle TPS, can now support Varian ARIA and Eclipse. The new EcCk software has been tested and worked well in physics new start plan check, IMRT plan integrity and plan quality checks. Conclusion: Methods and computer programs have been implemented to allow EcCk to support Varian ARIA and Eclipse systems. This project was supported by a research grant from Varian Medical System.

It is important to control and maintain water quality for nuclear power plants. Chemical engineers sample and monitor reactor water from various subsystems and analyze the chemical quality as routine operations. With regard to controlling water quality, new technologies have been developed and introduced to improve the water quality from both operation and material viewpoints. To maintain the quality, it is important to support chemical engineers in evaluating the water quality and realizing effective retrieval of stored data and documents. We have developed a remote support system using the Internet to diagnose BWR water quality, which we call e-chem page. The e-chem page integrates distributed data and information in a Web server, and makes it easy to evaluate the data on BWR water chemistry. This system is composed of four functions: data transmission, water quality evaluation, inquiry and history retrieval system, and reference to documents on BWR water chemistry. The developed system is now being evaluated in trial operations by Hitachi, Ltd. and an electric power company. In addition diagnosis technology applying independent component analysis (ICA) is being developed to improve predictive capability of the system. This paper describes the structure and function of the e-chem page and presents results of obtained with the proposed system for the prediction of chemistry conditions in reactor water. (authors)
The quality management journey: the progress of health facilities in Australia.

Many facilities in Australia have taken the Total Quality Management (TQM) step. The objective of this study was to examine progress of adopted formal quality systems in health. Sixty per cent of organizations surveyed have adopted formal systems. Of these, Deming adherents are the most common, followed by eclectic choices. Only 35% considered the quality transition as reasonably easy. There was no relationship between accreditation and formal quality systems identified. The most common improvement techniques were: flow charts, histograms, and cause and effect diagrams. Quality practitioners are happy to use several tools exceptionally well rather than have many tools at their disposal. The greatest impediment to the adoption of quality was the lack of top management support. This study did not support the view that clinicians are not readily actively supporting quality initiatives. Total Quality Management is not a mature concept; however, Chief Executive Officers are assured that rewards will be realized over time.

OSIRIS multi object spectrograph uses a set of user-customised-masks, which are manufactured on-demand. The manufacturing process consists of drilling the specified slits on the mask with the required accuracy. Ensuring that slits are on the right place when observing is of vital importance. We present a tool for checking the quality of the process of manufacturing the masks which is based on analyzing the instrument images obtained with the manufactured masks on place. The tool extracts the slit information from these images, relates specifications with the extracted slit information, and finally communicates to the operator if the manufactured mask fulfills the expectations of the mask designer. The proposed tool has been built using scripting languages and using standard libraries such as opencv, pyraf and scipy. The software architecture, advantages and limits of this tool in the lifecycle of a multiobject acquisition are presented.

Medical errors and unanticipated negative patient outcomes can damage the well-being of health care providers. These affected individuals, referred to as "second victims," can experience various psychological and physical symptoms. Support resources provided by health care organizations to prevent and reduce second victim-related harm are often inadequate. In this study, we present the development and psychometric evaluation of the Second Victim Experience and Support Tool (SVEST), a survey instrument that can assist health care organizations to implement and track the performance of second victim support resources. The SVEST (29 items representing 7 dimensions and 2 outcome variables) was completed by 303 health care providers involved in direct patient care. The survey collected responses on second victim-related psychological and physical symptoms and the quality of support resources. Desirability of possible support resources was also measured. The SVEST was assessed for content validity, internal consistency, and construct validity with confirmatory factor analysis. Confirmatory factor analysis results suggested good model fit for the survey. Cronbach α reliability scores for the survey dimensions ranged from 0.61 to 0.89. The most desired second victim support option was "A respected peer to discuss the details of what happened." The SVEST can be used by health care organizations to evaluate second victim experiences of their staff and the quality of existing support resources. It can also provide health care organization leaders with information on second victim-related support resources most preferred by their staff. The SVEST can be administered before and after implementing new second victim resources to measure perceptions of effectiveness.

Beyer, N.; Helmreich, W.

2004-08-01

In a competitive environment, well defined processes become the strategic advantage of a company. Hence, targeted Quality Management ensures efficiency, trans- parency and, ultimately, customer satisfaction. In the particular context of a Space Test Centre, a num- ber of specific Quality Management standards have to be applied. According to the revision of ISO 9001 dur- ing 2000, and due to the adaptation of ECSS-Q20-07, process orientation and data analysis are key tasks for ensuring and evaluating the efficiency of a company's processes. In line with these requirements, an integrated management system for accessing the necessary infor- mation to support Quality Management and other proc- esses has been established. Some of its test-related fea- tures are presented here. Easy access to the integrated management system from any work place at IABG's Space Test Centre is ensured by means of an intranet portal. It comprises a full set of quality-related process descriptions, information on test facilities, emergency procedures, and other relevant in- formation. The portal's web interface provides direct access to a couple of external applications. Moreover, easy updating of all information and low cost mainte- nance are features of this integrated information system. The timely and transparent management of non- conformances is covered by a dedicated NCR database which incorporates full documentation capability, elec- tronic signature and e-mail notification of concerned staff. A search interface allows for queries across all documented non-conformances. Furthermore, print ver- sions can be generated at any stage in the process, e.g. for distribution to customers. Feedback on customer satisfaction is sought through a web-based questionnaire. The process is initiated by the responsible test manager through submission of an e- mail that contains a hyperlink to a secure website, ask- ing the customer to complete the brief online form, which is directly fed to a database
Sound quality prediction for engine-radiated noise

Diesel engine-radiated noise quality prediction is an important topic because engine noise has a significant impact on the overall vehicle noise. Sound quality prediction is based on subjective and objective evaluation of engine noise. The integrated satisfaction index (ISI) is proposed as a criterion for differentiate noise quality in the subjective evaluation, and five psychoacoustic parameters are selected for characterizing and analyzing the noise quality of the diesel engine objectively. The combination of support vector machines (SVM) and genetic algorithm (GA) is proposed in order to establish a model for predicting the diesel engine-radiated noise quality for all operation conditions. The performance of the GA-SVM model is compared with the BP neural network model, and the results show that the mean relative error of the GA-SVM model is smaller than the BP neural network model. The importance rank of the sound quality metrics to the ISI is indicated by the non-parametric correlation analysis. This study suggests that the GA-SVM model is very useful for accurately predicting the diesel engine-radiated noise quality.

Leeds Test Object TOR[MAM] has been designed to supplement the current FAXIL mammography test object TOR[MAX]. It contains a range of details that have a more natural radiographic appearance and has been designed as a test that more closely approximates the image quality achieved in clinical mammography. Physical aspects of the design and implementation of TOR[MAM] are presented. The TOR[MAM] has been used in a preliminary physical evaluation of the comparative image qualities produced by conventional (screen-film) and phostostimulable phosphor computed mammography and the results are discussed. TOR[MAX] results are also presented. The influence of digital image processing (enhancement) on the image quality of computed mammograms is also considered. The results presented indicate the sensitivity of TOR[MAM]. (author)

There is controversy surrounding the impact of workplace interventions aimed at improving social support and supervisory quality on absenteeism, productivity and financial outcomes. To determine the value of social support interventions for work outcomes. Databases were searched for systematic reviews between 2000 and 2012 to complete a synthesis of systematic reviews guided by the PRISMA statement and the IOM guidelines for systematic reviews. Assessment of articles for inclusion and methodological quality was conducted independently by at least two researchers, with differences resolved by consensus. The search resulted in 3363 titles of which 3248 were excluded following title/abstract review, leaving 115 articles that were retrieved and underwent full article review. 10 articles met the set inclusion criteria, with 7 focusing on social support, 2 on supervisory quality and 1 on both. We found moderate and limited evidence, respectively, that social support and supervisory quality interventions positively impact workplace outcomes. There is moderate evidence that social support and limited evidence that supervisory quality interventions have a positive effect on work outcomes.

The aim of this study was to investigate the relationship between major recent life events that occurred during the last 5 years, social and personal resources, and subjective quality of life (QoL). A total of 1801 participants from the general population (CoLaus/PsyCoLaus study) completed the Life Events Questionnaire, the Social Support Questionnaire, the NEO Five-Factor Inventory Revised, and the Manchester Short Assessment of Quality of Life. Major life events were modestly associated with the QoL (about 5 % of the explained variance). However, QoL was significantly related to perceived social support and personality traits (about 37 % of the explained variance). Particularly, perceived social support, extraversion and conscientiousness personality dimensions were positively linked to life satisfaction, whereas a high level of neuroticism was negatively associated with QoL. This study highlights the negative but temporary association between critical events and QoL. However, a combination of high conscientiousness and extraversion, and positive social support may explain better variances for a high-perceived QoL.

This study aimed to examine the role of social support and depression in predicting the quality of life among the elderly living in a rural Federal Land Development Authority (FELDA) community in Malaysia. A total of 162 elderly settlers of FELDA Sungai Tengi, aged 60 years and above, were selected by universal sampling method in this cross-sectional study. Three standardized instruments - the 12-item Short Form (SF-12), 15-item Geriatric Depression Scale (GDS-15) and Medical Outcome Study Social Support (MOS-Social Support) - were used to assess for quality of life, depression and social support. Quality of life of the elderly people in this community was high, especially in terms of physical components as compared to mental components. The mean scores for emotional role in the SF-12 was relatively the highest (90.74 ± 21.59) with social functioning being the lowest (30.35 ± 22.29). The results also showed that the mean value was higher for physical component summary (74.40) as compared to mental component summary (51.51). Approximately 23.5% suffered mild depression and only 2.5% had severe depression. This study showed that the elderly FELDA settlers have a high quality of life, mainly on the physical components of life and low rate of severe depression, a positive indicator of their psychological well-being. Social support in the form of emotional/informational support, and depression were significant factors related to their good quality of life. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

This paper discusses and questions the current metadata standards for learning objects from a pedagogical point of view. From a social constructivist approach, the paper discusses how learning objects can support problem based, self-governed learning activities. In order to support this approach......, it is argued that it is necessary to focus on learning activities rather than on learning objects. Further, it is argued that descriptions of learning objectives and learning activities should be separated from learning objects. The paper presents a new conception of learning objects which supports problem...... based, self-governed activities. Further, a new way of thinking pedagogy into learning objects is introduced. It is argued that a lack of pedagogical thinking in learning objects is not solved through pedagogical metadata. Instead, the paper suggests the concept of references as an alternative...
Data Quality Objectives for Regulatory Requirements for Hazardous and Radioactive Air Emissions Sampling and Analysis; FINAL

This document describes the results of the data quality objective (DQO) process undertaken to define data needs for state and federal requirements associated with toxic, hazardous, and/or radiological air emissions under the jurisdiction of the River Protection Project (RPP). Hereafter, this document is referred to as the Air DQO. The primary drivers for characterization under this DQO are the regulatory requirements pursuant to Washington State regulations, that may require sampling and analysis. The federal regulations concerning air emissions are incorporated into the Washington State regulations. Data needs exist for nonradioactive and radioactive waste constituents and characteristics as identified through the DQO process described in this document. The purpose is to identify current data needs for complying with regulatory drivers for the measurement of air emissions from RPP facilities in support of air permitting. These drivers include best management practices; similar analyses may have more than one regulatory driver. This document should not be used for determining overall compliance with regulations because the regulations are in constant change, and this document may not reflect the latest regulatory requirements. Regulatory requirements are also expected to change as various permits are issued. Data needs require samples for both radionuclides and nonradionuclide analytes of air emissions from tanks and stored waste containers. The collection of data is to support environmental permitting and compliance, not for health and safety issues. This document does not address health or safety regulations or requirements (those of the Occupational Safety and Health Administration or the National Institute of Occupational Safety and Health) or continuous emission monitoring systems. This DQO is applicable to all equipment, facilities, and operations under the jurisdiction of RPP that emit or have the potential to emit regulated air pollutants

The ability to recognize the same image projected to different retinal locations is critical for visual object recognition in natural contexts. According to many theories, the translation invariance for objects extends only to trained retinal locations, so that a familiar object projected to a nontrained location should not be identified. In another approach, invariance is achieved "online," such that learning to identify an object in one location immediately affords generalization to other locations. We trained participants to name novel objects at one retinal location using eyetracking technology and then tested their ability to name the same images presented at novel retinal locations. Across three experiments, we found robust generalization. These findings provide a strong constraint for theories of vision.

To assess the change in level of diabetes quality management in primary care groups and outpatient clinics after feedback and tailored support. This before-and-after study with a 1-year follow-up surveyed quality managers on six domains of quality management. Questionnaires measured organization of care, multidisciplinary teamwork, patient centeredness, performance results, quality improvement policy, and management strategies (score range 0-100%). Based on the scores, responders received feedback and a benchmark and were granted access to a toolbox of quality improvement instruments. If requested, additional support in improving quality management was available, consisting of an elucidating phone call or a visit from an experienced consultant. After 1 year, the level of quality management was measured again. Of the initially 60 participating care groups, 51 completed the study. The total quality management score improved from 59.8% (95% CI 57.0-62.6%) to 65.1% (62.8-67.5%; P quality management score (P = 0.001). Of the 44 participating outpatient clinics, 28 completed the study. Their total score changed from 65.7% (CI 60.3-71.1%) to 67.3% (CI 62.9-71.7%; P = 0.30). Only the results in the domain multidisciplinary teamwork improved (P = 0.001). Measuring quality management and providing feedback and a benchmark improves the level of quality management in care groups but not in outpatient clinics. The questionnaires might also be a useful asset for other diabetes care groups, such as Accountable Care Organizations. © 2015 by the American Diabetes Association.

Visual input typically includes a myriad of objects, some of which are selected for further processing. While these objects vary in shape and size, most evidence supporting object-based guidance of attention is drawn from paradigms employing two identical objects. Importantly, object size is a readily perceived stimulus dimension, and whether it modulates the distribution of attention remains an open question. Across four experiments, the size of the objects in the display was manipulated in a modified version of the two-rectangle paradigm. In Experiment 1, two identical parallel rectangles of two sizes (thin or thick) were presented. Experiments 2-4 employed identical trapezoids (each having a thin and thick end), inverted in orientation. In the experiments, one end of an object was cued and participants performed either a T/L discrimination or a simple target-detection task. Combined results show that, in addition to the standard object-based attentional advantage, there was a further attentional benefit for processing information contained in the thick versus thin end of objects. Additionally, eye-tracking measures demonstrated increased saccade precision towards thick object ends, suggesting that Fitts's Law may play a role in object-based attentional shifts. Taken together, these results suggest that object-based attentional selection is modulated by object width.

Human involvement influences traditional service quality evaluations, which triggers an evaluation's low accuracy, poor reliability and less impressive predictability. This paper proposes a method by employing a support vector machine (SVM) and Dempster-Shafer evidence theory to evaluate the service quality of a production process by handling a high number of input features with a low sampling data set, which is called SVMs-DS. Features that can affect production quality are extracted by a large number of sensors. Preprocessing steps such as feature simplification and normalization are reduced. Based on three individual SVM models, the basic probability assignments (BPAs) are constructed, which can help the evaluation in a qualitative and quantitative way. The process service quality evaluation results are validated by the Dempster rules; the decision threshold to resolve conflicting results is generated from three SVM models. A case study is presented to demonstrate the effectiveness of the SVMs-DS method.
Improving package structure of object-oriented software using multi-objective optimization and weighted class connections

Full Text Available The software maintenance activities performed without following the original design decisions about the package structure usually deteriorate the quality of software modularization, leading to decay of the quality of the system. One of the main reasons for such structural deterioration is inappropriate grouping of source code classes in software packages. To improve such grouping/modular-structure, previous researchers formulated the software remodularization problem as an optimization problem and solved it using search-based meta-heuristic techniques. These optimization approaches aimed at improving the quality metrics values of the structure without considering the original package design decisions, often resulting into a totally new software modularization. The entirely changed software modularization becomes costly to realize as well as difficult to understand for the developers/maintainers. To alleviate this issue, we propose a multi-objective optimization approach to improve the modularization quality of an object-oriented system with minimum possible movement of classes between existing packages of original software modularization. The optimization is performed using NSGA-II, a widely-accepted multi-objective evolutionary algorithm. In order to ensure minimum modification of original package structure, a new approach of computing class relations using weighted strengths has been proposed here. The weights of relations among different classes are computed on the basis of the original package structure. A new objective function has been formulated using these weighted class relations. This objective function drives the optimization process toward better modularization quality simultaneously ensuring preservation of original structure. To evaluate the results of the proposed approach, a series of experiments are conducted over four real-worlds and two random software applications. The experimental results clearly indicate the effectiveness

Infant massage programs have proved to be effective in enhancing post-natal development of highly risk infants, such as preterm newborns and drug or HIV exposed children. Less studies have focused on the role of infant massage in supporting the co-construction of early adult-child relationships. In line with this lack of literature, the present paper reports on a pilot study aimed at investigating longitudinally the quality of mother-child interactions, with specific reference to emotional availability (EA), in a group of mother-child pairs involved in infant massage classes. Moreover, associations between mother-child EA, maternal wellbeing, marital adjustment, and social support were also investigated, with the hypothesis to find a link between low maternal distress, high couple satisfaction and high perceived support and interactions of better quality in the dyads. The study involved 20 mothers and their children, aged between 2 and 7 months, who participated to infant massage classes. The assessment took place at three stages: at the beginning of massage course, at the end of it and at 1-month follow-up. At the first stage of assessment self-report questionnaires were administered to examine the presence of maternal psychiatric symptoms (SCL-90-R), perceived social support (MSPSS), and marital adjustment (Dyadic Adjustment Scale); dyadic interactions were observed and rated with the Emotional Availability Scales (Biringen, 2008) at each stage of data collection. The results showed a significant improvement in the quality of mother-child interactions, between the first and the last evaluation, parallel to the unfolding of the massage program, highlighting a general increase in maternal and child's EA. The presence of maternal psychological distress resulted associated with less optimal mother-child emotional exchanges, while the hypothesis regarding couple satisfaction and social support influence were not confirmed. These preliminary results, if replicated

To investigate the reproducibility of computed tomography (CT) imaging quality in respiratory-gated radiation treatment planning is essential in radiotherapy of movable tumors. Seven series of regular and six series of irregular respiratory motions were performed using a thorax dynamic phantom. For the regular respiratory motions, the respiratory cycle was changed from 2.5 to 4 s and the amplitude was changed from 4 to 10 mm. For the irregular respiratory motions, a cycle of 2.5 to 4 or an amplitude of 4 to 10 mm was added to the base data (id est (i.e.) 3.5-s cycle, 6-mm amplitude) every three cycles. Images of the object were acquired six times using respiratory-gated data acquisition. The volume of the object was calculated and the reproducibility of the volume was decided based on the variety. The registered image of the object was added and the reproducibility of the shape was decided based on the degree of overlap of objects. The variety in the volumes and shapes differed significantly as the respiratory cycle changed according to regular respiratory motions. In irregular respiratory motion, shape reproducibility was further inferior, and the percentage of overlap among the six images was 35.26% in the 2.5- and 3.5-s cycle mixed group. Amplitude changes did not produce significant differences in the variety of the volumes and shapes. Respiratory cycle changes reduced the reproducibility of the image quality in respiratory-gated CT.

Full Text Available Construction managers often face with projects containing multiple units wherein activities repeat from unit to unit. Therefore effective resource management is crucial in terms of project duration, cost and quality. Accordingly, researchers have developed several models to aid planners in developing practical and near-optimal schedules for repetitive projects. Despite their undeniable benefits, such models lack the ability of pure simultaneous optimization because existing methodologies optimize the schedule with respect to a single factor, to achieve minimum duration, total cost, resource work breaks or various combinations, respectively. This study introduces a novel approach called “opposition multiple objective symbiotic organisms search” (OMOSOS for scheduling repetitive projects. The proposed algorithm used an opposition-based learning technique for population initialization and for generation jumping. Further, this study integrated a scheduling module (M1 to determine all project objectives including time, cost, quality and interruption. The proposed algorithm was implemented on two application examples in order to demonstrate its capabilities in optimizing the scheduling of repetitive construction projects. The results indicate that the OMOSOS approach is a powerful optimization technique and can assist project managers in selecting appropriate plan for project.

Quality assurance (QA) objectives for Phase 2 were that (1) scientific data generated would withstand scientific and legal scrutiny; (2) data would be gathered using appropriate procedures for sample collection, sample handling and security, chain of custody, laboratory analyses, and data reporting; (3) data would be of known precision and accuracy; and (4) data would meet data quality objectives defined in the Phase 2 Sampling and Analysis Plan. A review of the QA systems and quality control (QC) data associated with the Phase 2 investigation is presented to evaluate whether the data were of sufficient quality to satisfy Phase 2 objectives. The data quality indicators of precision, accuracy, representativeness, comparability, completeness, and sensitivity were evaluated to determine any limitations associated with the data. Data were flagged with qualifiers that were associated with appropriate reason codes and documentation relating the qualifiers to the reviewer of the data. These qualifiers were then consolidated into an overall final qualifier to represent the quality of the data to the end user. In summary, reproducible, precise, and accurate measurements consistent with CRRI objectives and the limitations of the sampling and analytical procedures used were obtained for the data collected in support of the Phase 2 Remedial Investigation.

Basili, Victor R.; Briand, Lionel C.; Melo, Walcelio

1997-01-01

This paper presents the results of a study in which we empirically investigated the suits of object-oriented (00) design metrics introduced in another work. More specifically, our goal is to assess these metrics as predictors of fault-prone classes and, therefore, determine whether they can be used as early quality indicators. This study is complementary to the work described where the same suite of metrics had been used to assess frequencies of maintenance changes to classes. To perform our validation accurately, we collected data on the development of eight medium-sized information management systems based on identical requirements. All eight projects were developed using a sequential life cycle model, a well-known 00 analysis/design method and the C++ programming language. Based on empirical and quantitative analysis, the advantages and drawbacks of these 00 metrics are discussed. Several of Chidamber and Kamerer's 00 metrics appear to be useful to predict class fault-proneness during the early phases of the life-cycle. Also, on our data set, they are better predictors than 'traditional' code metrics, which can only be collected at a later phase of the software development processes.
Facing Spousal Cancer During Child-Rearing Years: Do Social Support and Hardiness Moderate the Impact of Psychological Distress on Quality of Life?

Partners of cancer patients report psychological distress and reduced quality of life. However, partners' mental health status and quality of life during child-rearing years and the influence of social support and hardiness on their well-being have not yet been studied. The aim of this study was to describe psychological distress, quality of life, social support, and hardiness of the partners facing spousal cancer during child-rearing years and investigate whether social support or hardiness moderated the relationship between psychological distress and quality of life. Cross-sectional data were collected in Norway from December 2013 to July 2015 as part of the Cancer-PEPSONE study. Five questionnaires were administered to 14 females and 21 males (n = 35). Participants reported more psychological distress and lower quality-of-life scores than other healthy Norwegian populations. Psychological distress seemed to be associated with their not being in control of their futures. Received social support moderated the effect of psychological distress on quality of life. Facing spousal cancer during child-rearing years seemed to have a substantial impact on partners' mental health and an adverse impact on their quality of life. Accordingly, these partners' self-care abilities may be reduced. Received social support may reduce the multiple burdens and consequently allow for enhancement of self-care. Interventions should aim to improve the social support provided to child-rearing partners, which may improve their quality of life. Providing adequate information about their partner's cancer illness and treatment may enhance their feelings of control, which may be beneficial for their mental health status.

A concept of object-oriented intelligent CAD/CAE environment is proposed for the conceptual designing of advanced nuclear reactor system. It is composed of (i) object-oriented frame-structure database which represents the hierarchical relationship of the composite elements of reactor core and the physical properties, and (ii) object-oriented modularization of the elementary calculation processes, which are needed for reactor core design analysis. As an example practise, an object-oriented frame structure is constructed for representing a 3D configuration of a special fuel element of a space reactor design, by using a general-purpose expert system shell ESHELL/X.

1997-01-01

In 1996, the Joint Commission International (JCI), which is a partnership between the Joint Commission on Accreditation of Healthcare Organizations and Quality Healthcare Resources, Inc., became one of the contractors of the Quality Assurance Project (QAP). JCI recognizes the link between accreditation and quality, and uses a collaborative approach to help a country develop national quality standards that will improve patient care, satisfy patient-centered objectives, and serve the interest of all affected parties. The implementation of good standards provides support for the good performance of professionals, introduces new ideas for improvement, enhances the quality of patient care, reduces costs, increases efficiency, strengthens public confidence, improves management, and enhances the involvement of the medical staff. Such good standards are objective and measurable; achievable with current resources; adaptable to different institutions and cultures; and demonstrate autonomy, flexibility, and creativity. The QAP offers the opportunity to approach accreditation through research efforts, training programs, and regulatory processes. QAP work in the area of accreditation has been targeted for Zambia, where the goal is to provide equal access to cost-effective, quality health care; Jordan, where a consensus process for the development of standards, guidelines, and policies has been initiated; and Ecuador, where JCI has been asked to help plan an approach to the evaluation and monitoring of the health care delivery system.

Life balance is associated to health, well-being and quality of life and is a target of psychiatric rehabilitation interventions. However, little is known about this life dimension in women living with personality disorders. The purpose of this descriptive-correlational study was to compare and explore relationships between subjective life balance, objective time use, quality of life and perceived stress in women without a mental health disorder (n = 43) and women with a personality disorder (clusters B and C) (n = 30), aged between 18 and 50 years old. The variables were measured with the Life Balance Inventory (subjective life balance), the Occupational Questionnaire (objective time use), the Depression Anxiety Stress Scale (perceived stress) and the Quality of Life Index (satisfaction and importance with life domains). The analyses showed that women with a personality disorder spend significantly less time in work but more time in daily tasks and leisure. Subjective life balance, quality of life and perceived stress were significantly lower in women with a personality disorder (p life balance was explained by quality of life (R 2 = 27.5 %). In women without a mental illness, subjective life balance was explained by quality of life and motherhood (R 2 = 36.1 %). To support the recovery of women with personality disorders and their quality of life, it is important to address objective and subjective time use to enable accomplishment of a variety of meaningful activities.

In April 1999 the Swedish Parliament adopted fifteen national environmental quality objectives, describing what quality and state of the environment and the natural and cultural resources of Sweden are ecologically sustainable in the long term. In a series of decisions from 2001 to 2003, Parliament has subsequently adopted a total of seventy-one interim targets, indicating the direction and timescale of the action to be taken to achieve the fifteen objectives. In this, its third annual report to the Government, the Environmental Objectives Council presents its appraisal of progress towards the objectives. The main body of the report deals with the fifteen environmental quality objectives. The fold-out diagram on the inside front cover gives a summary of the assessments made, symbolized by smiley and less cheerful faces. Our assessments answer the questions: Will the environmental quality objectives be achieved by 2020 (or 2050, as a first step, in the case of the climate objective), and will the interim targets be met within the time-frames laid down for each of them. This year's report also deals - very briefly - with the four broader issues, related to the objectives, that are referred to in the Environmental Objectives Bill: 'The Swedish Environmental Objectives - Interim Targets and Action Strategies' (2001). It is very important that the values and principles which these issues represent are pursued and upheld as efforts to implement the environmental objectives continue. In addition, de Facto 2004 offers a few glimpses of how businesses and local authorities are working to achieve a better environment. This chapter of the report is based on interviews and information from Sweden's county administrative boards. For further information about the country's environmental goals, readers are referred to the Environmental Objectives Portal, miljomal.nu. The ultimate aim of our endeavour to attain the environmental quality objectives is to ensure that the next

This document describes the data quality objectives to select archived samples located at the 222-S Laboratory for Fluid Bed Steam Reformer testing. The type, quantity and quality of the data required to select the samples for Fluid Bed Steam Reformer testing are discussed. In order to maximize the efficiency and minimize the time to treat Hanford tank waste in the Waste Treatment and Immobilization Plant, additional treatment processes may be required. One of the potential treatment processes is the fluid bed steam reformer (FBSR). A determination of the adequacy of the FBSR process to treat Hanford tank waste is required. The initial step in determining the adequacy of the FBSR process is to select archived waste samples from the 222-S Laboratory that will be used to test the FBSR process. Analyses of the selected samples will be required to confirm the samples meet the testing criteria.
Association between social support and health-related quality of life among Chinese seafarers: A cross-sectional study.

Full Text Available Seafarers have reported impaired health and health-related quality of life (HRQOL. Social support might increase HRQOL, but little is known about this association among Chinese seafarers. The aim of this study was to describe social support and explore its association with HRQOL among Chinese seafarers.A cross-sectional survey was conducted in the ports of Nantong and Rugao, China, from April to December 2013. A total of 917 Chinese seafarers were interviewed on social support, mental distress, perceived occupational stress, and HRQOL using the following self-administered questionnaires: The Social Support Rating Scale, Self-rating Depression Scale, Occupational Stress Questionnaire, and the World Health Organization Quality of Life-BREF (WHOQOL-BREF questionnaire. Hierarchical linear regression modelling was used to analyze the association between seafarers' subjective level of social support and their HRQOL.Of the 917 male Chinese seafarers included in the study, 40.7% perceived high levels of social support, and 39.1% were highly satisfied with their overall quality of life (QOL. Hierarchical regression analysis showed significant associations between level of social support and all health dimensions in the WHOQOL-BREF, even after adjusting for depressive symptoms, occupational stress, occupational activities, sleep duration, and other relevant covariates. Compared with the medium or low level social support group, seafarers with a high level of social support had better QOL scores in the general facet health and QOL (β = 2.43, p<0.05, and the physical health (β = 3.23, p<0.001, psychological health (β = 5.56, p<0.001, social relation (β = 6.07, p<0.001, and environment domains (β = 4.27, p<0.001. In addition, depression, occupational stress, occupational activities, and sleep duration were found to be determinants of seafarers' HRQOL.Chinese seafarers have poorer HRQOL than the general population, but social support has a significant

Literature has well noted ethnic/racial disparities in cancer survival and cancer care. However, socioeconomic disparities in psychosocial adjustment to breast cancer have garnered little attention. This study addresses the research gap by investigating the associations between socioeconomic indicators (ie, education, annual personal, and household income) and quality of life (QOL) and the mediating roles of social support and social constraints (objective and subjective conditions that constrain individuals from disclosing cancer concerns) in these associations among Chinese American breast cancer survivors (CABCS). Ninety-six CABCS completed questionnaires assessing these variables. After controlling for stage of cancer, annual personal and household income had indirect effects on QOL through social support, and education showed indirect effect on QOL through social support and social constraints. Subscale analyses indicated that controlling for years of immigration, annual personal and household income showed indirect effect on functional well-being through social support. When controlling for stage of cancer and income, education showed indirect effects on physical well-being through social support and social constraints and showed both direct and indirect effects on breast cancer concerns through social constraints. This study suggested that socioeconomic indicators, education, and income could be associated with different aspects of QOL through unique interpersonal mechanisms among CABCS. Our findings implied that increasing social support and reducing social constraints when implementing psychosocial interventions for CABCS may help to address the SES-related health disparities.

Full Text Available Background: Cataract surgery (CS drastically increases the capacity for light reception to the retina. Several previous studies have suggested the beneficial effect of CS on subjectively measured sleep quality; however, the association between CS and objectively measured sleep quality remains uncertain. Methods: To evaluate the association between CS and objectively measured sleep quality in home settings, we conducted a cross-sectional study in 1037 elderly individuals (mean age, 71.9 years. We evaluated actigraphically measured sleep quality, urinary 6-sulfatoxymelatonin excretion, and ambulatory light levels, in addition to CS status. Results: The CS group (n = 174 showed significantly higher sleep efficiency and shorter wake after sleep onset than the no CS group (n = 863, even after adjustment for age, gender, body mass index, current smoking status, alcohol consumption, hypertension, diabetes, sleep medication, bedtime, rising time, daytime physical activity, daytime and nighttime light exposure, and urinary 6-sulfatoxymelatonin excretion (sleep efficiency: 85.8% in the CS group vs 84.4% in the no CS group, P = 0.042; wake after sleep onset: 45.7 min vs 50.6 min, respectively, P = 0.033. In contrast, urinary 6-sulfatoxymelatonin excretion, sleep onset latency, total sleep time, and sleep-mid time did not differ significantly between the CS and no CS groups. Conclusions: Among a community-dwelling elderly population, CS is significantly associated with objectively measured sleep quality, but urinary levels of melatonin metabolite do not differ between individuals with and without CS. These associations are independent of daily light exposure profiles.

The OKS (Object Kernel Support) is a library to support a simple, active persistent in-memory object manager. It is suitable for applications which need to create persistent structured information with fast access but do not require full database functionality. It can be used as the frame of configuration databases and real-time object managers for Data Acquisition and Detector Control Systems in such fields as setup, diagnostics and general configuration description. OKS is based on an object model that supports objects, classes, associations, methods, inheritance, polymorphism, object identifiers, composite objects, integrity constraints, schema evolution, data migration and active notification. OKS stores the class definitions and their instances in portable ASCII files. It provides query facilities, including indices support. The OKS has a C++ API (Application Program Interface) and includes Motif based GUI applications to design class schema and to manipulate objects. OKS has been developed on top of the Rogue Wave Tools h++ C++ class library

Alcohol consumption and problems are associated with interpersonal difficulties. We used a twin design to assess in men the degree to which genetic or environmental influences contributed to the covariance between alcohol consumption and problems, romantic quality and social support. The sample included adult male-male twin pairs (697 monozygotic and 487 dizygotic) for whom there were interview-based data on: alcohol consumption (average monthly alcohol consumption in the past year); alcohol problems (lifetime alcohol dependence symptoms); romantic conflict and warmth; friend problems and support; and relative problems and support. Key findings were that genetic and unique environmental factors contributed to the covariance between alcohol consumption and romantic conflict; genetic factors contributed to the covariance between alcohol problems and romantic conflict; and common and unique environmental factors contributed to the covariance between alcohol problems and friend problems. Recognizing and addressing the overlapping genetic and environmental influences that alcohol consumption and problems share with romantic quality and other indicators of social support may have implications for substance use prevention and intervention efforts.

As great emphasis is rightly placed upon the importance of assessment to judge the quality of our future healthcare professionals, it is appropriate not only to choose the most appropriate assessment method, but to continually monitor the quality of the tests themselves, in a hope that we may continually improve the process. This article stresses the importance of quality control mechanisms in the exam cycle and briefly outlines some of the key psychometric concepts including reliability measures, factor analysis, generalisability theory and item response theory. The importance of such analyses for the standard setting procedures is emphasised. This article also accompanies two new AMEE Guides in Medical Education (Tavakol M, Dennick R. Post-examination Analysis of Objective Tests: AMEE Guide No. 54 and Tavakol M, Dennick R. 2012. Post examination analysis of objective test data: Monitoring and improving the quality of high stakes examinations: AMEE Guide No. 66) which provide the reader with practical examples of analysis and interpretation, in order to help develop valid and reliable tests.

Due to a very large number of connected virtual objects in the surrounding environment, intelligent service features in the Internet of Things requires the reuse of existing virtual objects and composite virtual objects. If a new virtual object is created for each new service request, then the number of virtual object would increase exponentially. The Web of Objects applies the principle of service modularity in terms of virtual objects and composite virtual objects. Service modularity is a key concept in the Web Objects-Enabled Internet of Things (IoT) environment which allows for the reuse of existing virtual objects and composite virtual objects in heterogeneous ontologies. In the case of similar service requests occurring at the same, or different locations, the already-instantiated virtual objects and their composites that exist in the same, or different ontologies can be reused. In this case, similar types of virtual objects and composite virtual objects are searched and matched. Their reuse avoids duplication under similar circumstances, and reduces the time it takes to search and instantiate them from their repositories, where similar functionalities are provided by similar types of virtual objects and their composites. Controlling and maintaining a virtual object means controlling and maintaining a real-world object in the real world. Even though the functional costs of virtual objects are just a fraction of those for deploying and maintaining real-world objects, this article focuses on reusing virtual objects and composite virtual objects, as well as discusses similarity matching of virtual objects and composite virtual objects. This article proposes a logistic model that supports service modularity for the promotion of reusability in the Web Objects-enabled IoT environment. Necessary functional components and a flowchart of an algorithm for reusing composite virtual objects are discussed. Also, to realize the service modularity, a use case scenario is

This research examined two premises of supported housing: (a) that consumer choice/control over housing and support and the quality of housing are important contributors to the subjective quality of life and adaptation to community living of people with mental illness, and (b) that apartments provide mental health consumers with more choice/control over housing and support than group living arrangements. To test these two hypotheses, we collected data from participants with mental illness housed through a government initiative in Ontario, Canada. A total of 130 participants completed a baseline interview, and 91 of those participants also completed a follow-up interview 9-months later. Support was found for both hypotheses. The results were discussed in terms of the paradigm of supported housing, previous research, and implications for housing policy and program development in the community mental health sector.

Full Text Available Local residents play an important role in the process of sustainable development in tourism. Resident support for tourism development contributes to the health of tourism industry and successful community development. Therefore, it is in the best interest of local residents, the tourism industry, and tourists, that residents have a positive outlook on and positive experiences with tourism development. In order to understand resident support for tourism development from tourism impacts and community quality of life perspective within the rural communities of Orange County, Indiana, USA, this study has examined a proposed structural model which incorporates eight latent variables: (a six types of positive and negative tourism impacts serve as exogenous latent variables; (b tourism-related community quality of life (TCQOL is proposed as the mediating variable; and (c resident support for tourism development is the ultimate dependent variable. The results show that both sociocultural and environmental benefits contribute to the host community’s living experience. Economic and sociocultural benefits, negative sociocultural and environmental impacts, and TCQOL influence resident support for tourism development. This study identified specific tourism impacts that affect TCQOL and resident support for local tourism development. This study affirms that community quality of life (QOL serves an effective predictor of support for tourism development.
Technical and human considerations in establishing quality of supply objectives

International Nuclear Information System (INIS)

Fraser, J.C.

1989-01-01

The standard adopted for the quality of electrical supply ultimately determines the cost of the supply. Technical considerations prevent the achievement of perfect quality at any cost and high quality is gained usually only at high cost. Customer opinion ultimately determines acceptable quality and cost. However, gaining opinion data which is useful for system design is a task that must account for certain human characteristics which influence the reliability of data obtained from surveys. An overview is given of technical factors which limit the quality of supply and human nature impacts on opinion data. Power generation, generation design criteria, transmission system design criteria and subtransmission and distribution criteria for reliability of supply are discussed. Public opinion of electrical power quality is distorted by several influences. While electricity use is continuous, bills come periodically, and the time discrepancy is likely to inflate the perception of energy cost. Periods with low quality problems become expected as the norm, although to a certain degree memory of poor performance is more persistant than memory of good performance, moderating the effect. Costs customers are willing to bear to provide for improved performance are analyzed. 10 refs., 8 figs., 3 tabs

Next-generation infrared astronomical instrumentation for ground-based and space telescopes could be based on MOEMS programmable slit masks for multi-object spectroscopy (MOS). This astronomical technique is used extensively to investigate the formation and evolution of galaxies. We propose to develop a 2048x1080 DMD-based MOS instrument to be mounted on the Galileo telescope and called BATMAN. A two-arm instrument has been designed for providing in parallel imaging and spectroscopic capabilities. The two arms with F/4 on the DMD are mounted on a common bench, and an upper bench supports the detectors thanks to two independent hexapods. Very good optical quality on the DMD and the detectors will be reached. ROBIN, a BATMAN demonstrator, has been designed, realized and integrated. It permits to determine the instrument integration procedure, including optics and mechanics integration, alignment procedure and optical quality. First images have been obtained and measured. A DMD pattern manager has been developed in order to generate any slit mask according to the list of objects to be observed; spectra have been generated and measured. Observation strategies will be studied and demonstrated for the scientific optimization strategy over the whole FOV. BATMAN on the sky is of prime importance for characterizing the actual performance of this new family of MOS instruments, as well as investigating the operational procedures on astronomical objects. This instrument will be placed on the Telescopio Nazionale Galileo at the beginning of next year, in 2014.

We describe an experimental object-oriented programming language, ASL2, that supports program development by means of a series of abstraction steps. The language allows immediate object construction, and it is possible to use the constructed objects for concrete problem solving tasks. Classes...... restrictive. As a central mechanism, weakly classified objects are allowed to borrow methods from each other. ASL2 supports class generalization, as a counterpart to class specialization and inheritance in mainstream object-oriented programming languages. The final abstraction step discussed in this paper...

Objective Evaluate outcomes of the lengthening temporalis myoplasty in facial reanimations. Study Design Case series with planned data collection. Setting Ospedali Riuniti, Bergamo, and AOUC Careggi, Florence, Italy. Subjects and Methods From 2011 to 2016, 11 patients underwent lengthening temporalis myoplasty; demographic data were collected for each. Pre- and postoperative photographs and videos were recorded and used to measure the smile angle and the excursion of the oral commissure, according to the SMILE system (Scaled Measurements of Improvement in Lip Excursion). All patients were tested with the Facial Disability Index, and they also completed a questionnaire about the adherence to physiotherapy indications. Results All patients demonstrated a significant improvement in functional parameters and in quality of life. On the reanimated side, the mean z-line and a-value, measured when smiling, significantly improved in all patients: from 22.6 mm (95% CI, 20.23-25.05) before surgery to 30.9 mm (95% CI, 27.82-33.99) after surgery ( P smile at the reanimated side, was 3.1 mm (95% CI, 1.30-4.88) for the z-line and 3.3° (95% CI, 1.26°-5.29°) for the a-value. The Facial Disability Index score increased from a preoperative mean of 33.4 points (95% CI, 28.25-38.66) to 49.9 points (95% CI, 47.21-52.60) postoperatively ( P smile reanimation, with satisfying functional and quality-of-life outcomes.

Objective. Neurophysiological correlates of vertical disparity in 3D images are studied in an objective approach using EEG technique. These disparities are known to negatively affect the quality of experience and to cause visual discomfort in stereoscopic visualizations. Approach. We have presented four conditions to subjects: one in 2D and three conditions in 3D, one without vertical disparity and two with different vertical disparity levels. Event related potentials (ERPs) are measured for each condition and the differences between ERP components are studied. Analysis is also performed on the induced potentials in the time frequency domain. Main results. Results show that there is a significant increase in the amplitude of P1 components in 3D conditions in comparison to 2D. These results are consistent with previous studies which have shown that P1 amplitude increases due to the depth perception in 3D compared to 2D. However the amplitude is significantly smaller for maximum vertical disparity (3D-3) in comparison to 3D with no vertical disparity. Our results therefore suggest that the vertical disparity in 3D-3 condition decreases the perception of depth compared to other 3D conditions and the amplitude of P1 component can be used as a discriminative feature. Significance. The results show that the P1 component increases in amplitude due to the depth perception in the 3D stimuli compared to the 2D stimulus. On the other hand the vertical disparity in the stereoscopic images is studied here. We suggest that the amplitude of P1 component is modulated with this parameter and decreases due to the decrease in the perception of depth.

The well-being of patients undergoing chemotherapy treatment for colorectal cancer (CRC) is affected by psychological effects associated with cancer treatment. However, little is known about the impact of these psychological factors in Brazilian patients with CRC. The aim of this study was to determine whether perceived stress, social support, and resilience are associated with quality of life in urban Brazilian patients receiving chemotherapy treatment for CRC. This was a cross-sectional study conducted with 144 Brazilian CRC patients in an ambulatory oncology clinic. The participants completed 5 questionnaires: Demographics, Perceived Stress Scale 14, Social Support Satisfaction Scale, Resilience Scale, and European Organization for Research and Treatment of Cancer Quality of Life Questionnaires (C30 and CR29). Confirmatory factor analysis modeling and Cronbach's α were used to examine construct validity and internal consistency. We used the MPlus 3.0 to construct and validate the structural model. There was a moderate and positive effect of resilience on the physical, social, and emotional aspects of quality of life. Social support had a strong and positive direct effect on quality of life (ie, social, physical, social, and emotional). Social support had a negative effect on stress perception. Resilience was also negatively related to stress perception. Family support and professional social support are important factors for Brazilian CRC patients. Resilience is an important ally for patients. It is important for nurses to consider this when developing educational and psychological interventional strategies to reduce stress and ultimately improve quality of life in this population. Psychological factors that improve quality of life should be evaluated in patients undergoing treatment for cancer.

Anxiety and depression are among the most common psychosocial problems with gynecologic cancer patients. In this respect, "social support" has become a key tool in the patients' coping with the aforementioned risk factors as an important contributor to their well-being. The purpose of this study was to assess the relationship between social support and the level of anxiety, depression, and quality of life of Turkish women with gynecologic cancer. In a hospital in Turkey, 187 women with a diagnosis of gynecologic cancer comprised a convenience sample and completed 4 study instruments in a cross-sectional design. Statistically significant correlations among type of perceived social support, quality of life, anxiety, and depression (P social support was associated with increased quality of life, it was also associated with reduced anxiety and depression rates. Our study showed that the type of perceived social support by the patients with cancer had significant effect on depression, anxiety, and quality of life. Social support is a powerful tool that can mediate the effects of difficult life stressors and decrease the incidence of mood disorders, and, therefore, greater importance should be attached to it in the realm of cancer treatment. Supported by the collaborative efforts of family members and healthcare professionals, cancer patients will more easily cope with the drawbacks of their state.

Conceptualizing and Measuring the Quality of Democracy: The Citizens’ Perspective

Directory of Open Access Journals (Sweden)

Dieter Fuchs

2018-03-01

Full Text Available In recent years, several measurements of the quality of democracy have been developed (e.g. Democracy Barometer, Varieties of Democracy Project. These objective measurements focus on institutional and procedural characteristics of democracy. This article starts from the premise that in order to fully understand the quality of democracy such objective measurements have to be complemented by subjective measurements based on the perspective of citizens. The aim of the article is to conceptualize and measure the subjective quality of democracy. First, a conceptualization of the subjective quality of democracy is developed consisting of citizens’ support for three normative models of democracy (electoral, liberal, and direct democracy. Second, based on the World Values Survey 2005–2007, an instrument measuring these different dimensions of the subjective quality of democracy is suggested. Third, distributions for different models of democracy are presented for some European and non-European liberal democracies. They reveal significant differences regarding the subjective quality of democracies. Fourth, the subjective quality of democracy of these countries is compared with the objective quality of democracy based on three indices (electoral democracy, liberal democracy and direct popular vote developed by the Varieties of Democracy (V-Dem Project. Finally, further research questions are discussed.
A study of the image quality of computed tomography adaptive statistical iterative reconstructed brain images using subjective and objective methods

2016-01-01

The recent reintroduction of iterative reconstruction in computed tomography has facilitated the realisation of major dose saving. The aim of this article was to investigate the possibility of achieving further savings at a site with well-established Adaptive Statistical iterative Reconstruction (ASiR TM ) (GE Healthcare) brain protocols. An adult patient study was conducted with observers making visual grading assessments using image quality criteria, which were compared with the frequency domain metrics, noise power spectrum and modulation transfer function. Subjective image quality equivalency was found in the 40-70% ASiR TM range, leading to the proposal of ranges for the objective metrics defining acceptable image quality. Based on the findings of both the patient-based and objective studies of the ASiR TM /tube-current combinations tested, 60%/305 mA was found to fall within all, but one, of these ranges. Therefore, it is recommended that an ASiR TM level of 60%, with a noise index of 12.20, is a viable alternative to the currently used protocol featuring a 40% ASiR TM level and a noise index of 11.20, potentially representing a 16% dose saving.

To assess the quality of nutrition content and the integration of user quality components and behaviour change theory relevant to food purchasing behaviour in a sample of existing mobile apps. Descriptive comparative analysis of eleven mobile apps comprising an assessment of their alignment with existing evidence on nutrition, behaviour change and user quality, and their potential ability to support healthier food purchasing behaviour. Mobile apps freely available for public use in GoogePlay were assessed and scored according to agreed criteria to assess nutrition content quality and integration of behaviour change theory and user quality components. A sample of eleven mobile apps that met predefined inclusion criteria to ensure relevance and good quality. The quality of the nutrition content varied. Improvements to the accuracy and appropriateness of nutrition content are needed to ensure mobile apps support a healthy behaviour change process and are accessible to a wider population. There appears to be a narrow focus towards behaviour change with an overemphasis on behavioural outcomes and a small number of behaviour change techniques, which may limit effectiveness. A significant effort from the user was required to use the mobile apps appropriately which may negatively influence user acceptability and subsequent utilisation. Existing mobile apps may offer a potentially effective approach to supporting healthier food purchasing behaviour but improvements in mobile app design are required to maximise their potential effectiveness. Engagement of mobile app users and nutrition professionals is recommended to support effective design.

Highlights: • A time-effective multi-objective design optimization scheme is proposed. • The scheme aims at exploring suitable 3E energy system for the specific case. • A realistic case located in China is used for the analysis. • Parametric study is investigated to test the effects of different parameters. - Abstract: Due to the increasing energy demands and global warming, energy quality management (EQM) for districts has been getting importance over the last few decades. The evaluation of the optimum energy systems for specific districts is an essential part of EQM. This paper presents a deep analysis of the optimum energy systems for a district sited in China. A multi-objective optimization approach based on Genetic Algorithm (GA) is proposed for the analysis. The optimization process aims to search for the suitable 3E (minimum economic cost and environmental burden as well as maximum efficiency) energy systems. Here, life cycle CO 2 equivalent (LCCO 2 ), life cycle cost (LCC) and exergy efficiency (EE) are set as optimization objectives. Then, the optimum energy systems for the Chinese case are presented. The final work is to investigate the effects of different energy parameters. The results show the optimum energy systems might vary significantly depending on some parameters

Sessional staff is increasingly involved in teaching at universities, playing a pivotal role in bridging the gap between theory and practice for students, especially in the health professions, including pharmacy. Although sessional staff numbers have increased substantially in recent years, limited attention has been paid to the quality of teaching and learning provided by this group. This review will discuss the training and support of sessional staff, with a focus on Australian universities, including the reasons for and potential benefits of training, and structure and content of training programs. Although sessional staff views these programs as valuable, there is a lack of in-depth evaluations of the outcomes of the programs for sessional staff, students and the university. Quality assurance of such programs is only guaranteed, however, if these evaluations extend to the impact of this training and support on student learning.

Objectives. We conducted case studies of 10 agencies that participated in early quality improvement efforts. Methods. The agencies participated in a project conducted by the National Association of County and City Health Officials (2007–2008). Case study participants included health directors and quality improvement team leaders and members. We implemented multiple qualitative analysis processes, including cross-case analysis and logic modeling. We categorized agencies according to the extent to which they had developed a quality improvement culture. Results. Agencies were conducting informal quality improvement projects (n = 4), conducting formal quality improvement projects (n = 3), or creating a quality improvement culture (n = 4). Agencies conducting formal quality improvement and creating a quality improvement culture had leadership support for quality improvement, participated in national quality improvement initiatives, had a greater number of staff trained in quality improvement and quality improvement teams that met regularly with decision-making authority. Agencies conducting informal quality improvement were likely to report that accreditation is the major driver for quality improvement work. Agencies creating a quality improvement culture were more likely to have a history of evidence-based decision-making and use quality improvement to address emerging issues. Conclusions. Our findings support previous research and add the roles of national public health accreditation and emerging issues as factors in agencies’ ability to create and sustain a quality improvement culture.

Quality plan and configuration management in complex systems

Gonzalez Junto, J.; Merchan Teyssiere

Since the Second World War, the philosophy behind the quality systems of industries and service companies has evolved to embrace the whole life cycle of the product, system or service. In this evolution process, quality has become a strategic factor in the survival of entreprises. The first steps in trying to establish quality systems were taken for the armed forces, followed by space, aeronautical and nuclear projects, whose products were more and more complex and sophisticated. These systems were established by means of quality plans or programmes, and their basic objective was to guarantee a high safety level for the user and/or the general population. In later years, the main concern was to reach a determined quality level not only in one phase of the product life, but in the complete life cycle of the final product. Today a new goal is established and pursued: better quality of the product, service or system life cycle at a lower cost. Methods of improving the quality of systems and processes are the subject of numerous initiatives and studies, to better availability and maintainability of complex equipment or installations, with an extended useful life and greater requirements. Experience in the performance of complex projects shows that a higher quality may be obtained through designing a comprehensive quality plan which pays special attention to information management and modifications of the original design. Obtaining a high reliability level for an installation (equipment, systems, etc), increasing its availability and rationalizing its maintenance may be little less than fanciful without a deep knowledge of the installation, of its activities and its current status in day-to-day operation, which shows the importance of truthful information available to operators and corresponding exactly to their needs. In this frame of mind, a quality plan comprising a configuration management system of information and documents constitutes the basic support tool for
Sweden's environmental objectives - are we getting there. A progress report from the Swedish Environmental Objectives Council. de Facto 2004

In April 1999 the Swedish Parliament adopted fifteen national environmental quality objectives, describing what quality and state of the environment and the natural and cultural resources of Sweden are ecologically sustainable in the long term. In a series of decisions from 2001 to 2003, Parliament has subsequently adopted a total of seventy-one interim targets, indicating the direction and timescale of the action to be taken to achieve the fifteen objectives. In this, its third annual report to the Government, the Environmental Objectives Council presents its appraisal of progress towards the objectives. The main body of the report deals with the fifteen environmental quality objectives. The fold-out diagram on the inside front cover gives a summary of the assessments made, symbolized by smiley and less cheerful faces. Our assessments answer the questions: Will the environmental quality objectives be achieved by 2020 (or 2050, as a first step, in the case of the climate objective), and will the interim targets be met within the time-frames laid down for each of them. This year's report also deals - very briefly - with the four broader issues, related to the objectives, that are referred to in the Environmental Objectives Bill: 'The Swedish Environmental Objectives - Interim Targets and Action Strategies' (2001). It is very important that the values and principles which these issues represent are pursued and upheld as efforts to implement the environmental objectives continue. In addition, de Facto 2004 offers a few glimpses of how businesses and local authorities are working to achieve a better environment. This chapter of the report is based on interviews and information from Sweden's county administrative boards. For further information about the country's environmental goals, readers are referred to the Environmental Objectives Portal, miljomal.nu. The ultimate aim of our endeavour to attain the environmental quality objectives is to
Industry funded clinical trials: bias and quality.

The quality of the clinical data supporting the development and ultimately the approval for medical use of new drugs is often challenged. Many share the perception that the business goals of the pharmaceutical industry overrule the best scientific efforts to accrue critical knowledge on a new molecule, in order to inform investment of resources, regulatory approvals and appropriate use by patients. Despite this common belief, few scientists have attempted to assess objectively the quality of industry funded (IF) clinical trials by measuring it and comparing it with non-industry funded (NIF) clinical trials in a data-driven fashion. Overall, the average quality of IF clinical research has been reported to be higher than the quality of NIF clinical research.

The current study addresses the well-known "figure/ground" problem in human perception, a fundamental topic that has received surprisingly little attention from touch scientists to date. Our approach is grounded in, and directly guided by, current knowledge concerning the nature of haptic processing. Given inherent figure/ground ambiguity in natural scenes and limited sensory inputs from first contact (a "haptic glance"), we consider first whether people are even capable of differentiating figure from ground (Experiments 1 and 2). Participants were required to estimate the strength of their subjective impression that they were feeling an object (i.e., figure) as opposed to just the supporting structure (i.e., ground). Second, we propose a tripartite factor classification scheme to further assess the influence of kinetic, geometric (Experiments 1 and 2), and material (Experiment 2) factors on haptic figure/ground segmentation, complemented by more open-ended subjective responses obtained at the end of the experiment. Collectively, the results indicate that under certain conditions it is possible to segment figure from ground via a single haptic glance with a reasonable degree of certainty, and that all three factor classes influence the estimated likelihood that brief, spatially distributed fingertip contacts represent contact with an object and/or its background supporting structure.

Adequate symptom and quality-of-life (SQL) management is a priority during cancer treatment. eHealth is a timely way to enhance patient-engagement, facilitate communication, and improve health outcomes. The objectives of this study were to describe patient and caregivers' perspectives for providing, processing, and managing SQL data to enhance communication and identify desired components for decision support. Data were collected from 64 participants through questionnaires and focus groups. Analysis was conducted using NVivo. Open and axial coding was completed, grouping commonalities and large constructs into nodes to identify and synthesize themes. Face-to-face meetings with clinicians were the prime time to communicate, and patients strove to understand treatment options and the effect on SQL by bringing caregivers to their visits, taking notes, tracking symptoms, and creating portable health records. Patients/caregivers struggled to self-manage their symptoms and were uncertain when to contact clinicians when experiencing uncontrolled symptoms. Most participants identified eHealth solutions for decision support. However, 38% of participants (n = 24) rarely used computers and identified non-eHealth options for decision support. Core components for both eHealth and non-eHealth systems were access to (1) cancer information, (2) medical records, (3) peer support, and (4) improved support and understanding on when to contact clinicians. Patients were faced with an overwhelming amount of information and relied on their caregivers to help navigate the complexities of cancer care and self-manage SQL. Health technologies can provide informational support; however, decision support needs to span multiple venues to avoid increasing disparities caused by a digital divide.

This study aimed to investigate the effect of temperament and character traits on perceived social support and quality of life in patients with epilepsy (PWE). Fifty-two PWE and 54 healthy controls were included in this study. Demographics and clinical data were recorded. Temperament and Character traits were investigated using Temperament and Character Inventory (TCI), Perceived Social Support was evaluated by Multidimensional Scale of Perceived Social Support Scale (MSPSS), and quality of life was assessed using a 36-Item Short-Form Health Survey (SF-36). Participants also completed the Hospital Anxiety Depression Scale (HADS). TCI and MSPSS scores showed no significant difference between the groups (p>0.05). Mental and physical subscales of SF-36 were significantly lower in PWE than the controls (p=0.012, p=0.020, respectively). Multiple linear regression analysis indicated that Reward Dependence and Cooperativeness were independent predictors for perceived social support, and Persistence score was an independent predictor for the physical subscale of SF-36 even after adjustment for confounding background variables (plife in PWE. Thus, an evaluation of temperament and character traits may play a significant role in preventing negative effects on perceived social support and quality of life in PWE.

No standardised tools for assessing the quality of specialist mental health supported accommodation services exist. To address this, we adapted the Quality Indicator for Rehabilitative care-QuIRC-that was originally developed to assess the quality of longer term inpatient and community based mental health facilities. The QuIRC, which is completed by the service manager and gives ratings of seven domains of care, has good psychometric properties. Focus groups with staff of the three main types of supported accommodation in the UK (residential care, supported housing and floating outreach services) were carried out to identify potential amendments to the QuIRC. Additional advice was gained from consultation with three expert panels, two of which comprised service users with lived experience of mental health and supported accommodation services. The amended QuIRC (QuIRC-SA) was piloted with a manager of each of the three service types. Item response variance, inter-rater reliability and internal consistency were assessed in a random sample of 52 services. Factorial structure and discriminant validity were assessed in a larger random sample of 87 services. The QuIRC-SA comprised 143 items of which only 18 items showed a narrow range of response and five items had poor inter-rater reliability. The tool showed good discriminant validity, with supported housing services generally scoring higher than the other two types of supported accommodation on most domains. Exploratory factor analysis showed that the QuIRC-SA items loaded onto the domains to which they had been allocated. The QuIRC-SA is the first standardised tool for quality assessment of specialist mental health supported accommodation services. Its psychometric properties mean that it has potential for use in research as well as audit and quality improvement programmes. A web based application is being developed to make it more accessible which will produce a printable report for the service manager about the

Quality of life, coping strategies, social support and self-efficacy are important psychosocial variables strongly affecting the experience of acute myocardial infarction (AMI) in women. To gain a more in-depth understanding of how coping strategies, self-efficacy, quality of life and social support shape women's adjustment to AMI. Mixed methods study. Quantitative data were collected through a standardised questionnaire on coping strategies, self-efficacy, quality of life and social support. Qualitative data stemmed from 57 semistructured interviews conducted with post-AMI female patients on related topics. Quantitative data were analysed with unpaired two-sample t-tests on the means, comparing women who experienced AMI (N = 77) with a control group of women who did not have AMI (N = 173), and pairwise correlations on the AMI sample. Qualitative data were grouped into coding families and analysed through thematic content analysis. Qualitative and quantitative results were then integrated, for different age groups. Quantitative results indicated statistically significant differences between women who experienced AMI and the control group: the former showed lower self-perceived health, perceived social support and social support coping, but greater self-efficacy, use of acceptance, avoidance and religious coping. Pairwise correlations showed that avoidance coping strategy was negatively correlated with quality of life, while the opposite was true for problem-oriented coping, perceived social support and self-efficacy. Qualitative results extended and confirmed quantitative results, except for coping strategies: avoidance coping seemed more present than reported in the standardised measures. Mixed methods provide understanding of the importance of social support, self-efficacy and less avoidant coping strategies to women's adjustment to AMI. Women need support from health professionals with knowledge of these topics, to facilitate their adaptation to AMI. © 2017

To conduct a systematic review of the literature to identify existing online primary care quality improvement tools and resources to support organisational improvement related to the seven elements in the Primary Care Practice Improvement Tool (PC-PIT), with the identified tools and resources to progress to a Delphi study for further assessment of relevance and utility. Systematic review of the international published and grey literature. CINAHL, Embase and PubMed databases were searched in March 2014 for articles published between January 2004 and December 2013. GreyNet International and other relevant websites and repositories were also searched in March-April 2014 for documents dated between 1992 and 2012. All citations were imported into a bibliographic database. Published and unpublished tools and resources were included in the review if they were in English, related to primary care quality improvement and addressed any of the seven PC-PIT elements of a high-performing practice. Tools and resources that met the eligibility criteria were then evaluated for their accessibility, relevance, utility and comprehensiveness using a four-criteria appraisal framework. We used a data extraction template to systematically extract information from eligible tools and resources. A content analysis approach was used to explore the tools and resources and collate relevant information: name of the tool or resource, year and country of development, author, name of the organisation that provided access and its URL, accessibility information or problems, overview of each tool or resource and the quality improvement element(s) it addresses. If available, a copy of the tool or resource was downloaded into the bibliographic database, along with supporting evidence (published or unpublished) on its use in primary care. This systematic review identified 53 tools and resources that can potentially be provided as part of a suite of tools and resources to support primary care practices in

Quality assurance and quality control are vital parts of highway runoff water-quality monitoring projects. To be effective, project quality assurance must address all aspects of the project, including project management responsibilities and resources, data quality objectives, sampling and analysis plans, data-collection protocols, data quality-control plans, data-assessment procedures and requirements, and project outputs. Quality control ensures that the data quality objectives are achieved as planned. The historical development and current state of the art of quality assurance and quality control concepts described in this report can be applied to evaluation of data from prior projects.

1997-01-01

The Flight Dynamics Division (FDD) of NASA's Goddard Space Flight Center (GSFC) recently embarked on a far-reaching revision of its process for developing and maintaining satellite support software. The new process relies on an object-oriented software development method supported by a domain specific library of generalized components. This Generalized Support Software (GSS) Domain Engineering Process is currently in use at the NASA GSFC Software Engineering Laboratory (SEL). The key facets of the GSS process are (1) an architecture for rapid deployment of FDD applications, (2) a reuse asset library for FDD classes, and (3) a paradigm shift from developing software to configuring software for mission support. This paper describes the GSS architecture and process, results of fielding the first applications, lessons learned, and future directions
Self-concept and quality of object relations as predictors of outcome in short- and long-term psychotherapy.

Quality of object relations and self-concept reflect clinically relevant aspects of personality functioning, but their prediction as suitability factors for psychotherapies of different lengths has not been compared. This study compared their prediction on psychiatric symptoms and work ability in short- and long-term psychotherapy. Altogether 326 patients, 20-46 years of age, with mood and/or anxiety disorder, were randomized to short-term (solution-focused or short-term psychodynamic) psychotherapy and long-term psychodynamic psychotherapy. The Quality of Object Relations Scale (QORS) and the Structural Analysis of Social Behavior (SASB) self-concept questionnaire were measured at baseline, and their prediction on outcome during the 3-year follow-up was assessed by the Symptom Check List Global Severity Index and the Anxiety Scale, the Beck Depression Inventory and by the Work Ability Index, Social Adjustment Scale work subscale and the Perceived Psychological Functioning scale. Negative self-concept strongly and self-controlling characteristics modestly predicted better 3-year outcomes in long-term therapy, after faster early gains in short-term therapy. Patients with a more positive or self-emancipating self-concept, or more mature object relations, experienced more extensive benefits after long-term psychotherapy. The importance of length vs. long-term therapy technique on the differences found is not known. Patients with mild to moderate personality pathology, indicated by poor self-concept, seem to benefit more from long-term than short-term psychotherapy, in reducing risk of depression. Long-term therapy may also be indicated for patients with relatively good psychological functioning. More research is needed on the relative importance of these characteristics in comparison with other patient-related factors. © 2013 Published by Elsevier B.V.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease. Previous studies showed that perceived social support has an important role in enhancing patient's quality of life (QOL). However, the precise mechanisms through which social support exerts such an effect are not completely understood. The aim of this paper is to test two alternative models explaining the relationship between social support (positive and problematic) and two dimensions of QOL: Health-Related (HR-QOL) and Non-Health-Related (NHR-QOL). Model A (mediation) hypothesized that positive support would reduce stress while problematic support would increase stress), and that this in turn would reduce QOL. Model B (moderation) hypothesized that the effect of support on QOL would be moderated by the experience of stress in that more stressed individuals would show stronger effects. Three hundred and forty-four Italian patients with SLE completed an online questionnaire. Stress partially mediated the relationship between support and QOL dimensions (either HR-QOL and NHR-QOL) thus supporting Model B. As hypothesized, positive support reduced stress, while problematic support increased stress. These findings help to explain the complex relationship between social support, stress and QOL in patients with SLE.

Although critical to health and well-being, relatively little research has been conducted in the organizational literature on linkages between the work-family interface and sleep. Drawing on Conservation of Resources theory, we use a sample of 623 information technology workers to examine the relationships between work-family conflict, family-supportive supervisor behaviors (FSSB), and sleep quality and quantity. Validated wrist actigraphy methods were used to collect objective sleep quality and quantity data over a one week period of time, and survey methods were used to collect information on self-reported work-family conflict, FSSB, and sleep quality and quantity. Results demonstrated that the combination of predictors (i.e., work-to-family conflict, family-to-work conflict, FSSB) was significantly related to both objective and self-report measures of sleep quantity and quality. Future research should further examine the work-family interface to sleep link and make use of interventions targeting the work-family interface as a means for improving sleep health. PMID:24730425

An object set offers an interface which is a disjoint union of the interfaces of its member objects. It may also be used...... for a special kind of method invocation involving multiple objects in a dynamic lookup process. With support for feature access and late-bound method calls object sets are similar to ordinary objects, only more flexible.

Monitoring And Modeling Environmental Water Quality To Support Environmental Water Purchase Decision-making

Null, S. E.; Elmore, L.; Mouzon, N. R.; Wood, J. R.

2016-12-01

More than 25 million cubic meters (20,000 acre feet) of water has been purchased from willing agricultural sellers for environmental flows in Nevada's Walker River to improve riverine habitat and connectivity with downstream Walker Lake. Reduced instream flows limit native fish populations, like Lahontan cutthroat trout, through warm daily stream temperatures and low dissolved oxygen concentrations. Environmental water purchases maintain instream flows, although effects on water quality are more varied. We use multi-year water quality monitoring and physically-based hydrodynamic and water quality modeling to estimate streamflow, water temperature, and dissolved oxygen concentrations with alternative environmental water purchases. We simulate water temperature and dissolved oxygen changes from increased streamflow to prioritize the time periods and locations that environmental water purchases most enhance trout habitat as a function of water quality. Monitoring results indicate stream temperature and dissolved oxygen limitations generally exist in the 115 kilometers upstream of Walker Lake (about 37% of the study area) from approximately May through September, and this reach acts as a water quality barrier for fish passage. Model results indicate that low streamflows generally coincide with critically warm stream temperatures, water quality refugia exist on a tributary of the Walker River, and environmental water purchases may improve stream temperature and dissolved oxygen conditions for some reaches and seasons, especially in dry years and prolonged droughts. This research supports environmental water purchase decision-making and allows water purchase decisions to be prioritized with other river restoration alternatives.
Making electronic health records support quality management: A narrative review.

Triantafillou, Peter

2017-08-01

Since the 1990s many hospitals in the OECD countries have introduced electronic health record (EHR) systems. A number of studies have examined the factors impinging on EHR implementation. Others have studied the clinical efficacy of EHR. However, only few studies have explored the (intermediary) factors that make EHR systems conducive to quality management (QM). Undertake a narrative review of existing studies in order to identify and discuss the factors conducive to making EHR support three dimensions of QM: clinical outcomes, managerial monitoring and cost-effectiveness. A narrative review of Web of Science, Cochrane, EBSCO, ProQuest, Scopus and three Nordic research databases. most studies do not specify the type of EHR examined. 39 studies were identified for analysis. 10 factors were found to be conducive to make EHR support QM. However, the contribution of EHR to the three specific dimensions of QM varied substantially. Most studies (29) included clinical outcomes. However, only half of these reported EHR to have a positive impact. Almost all the studies (36) dealt with the ability of EHR to enhance managerial monitoring of clinical activities, the far majority of which showed a positive relationship. Finally, only five dealt with cost-effectiveness of which two found positive effects. The findings resonates well with previous reviews, though two factors making EHR support QM seem new, namely: political goals and strategies, and integration of guidelines for clinical conduct. Lacking EHR type specification and diversity in study method imply that there is a strong need for further research on the factors that may make EHR may support QM. Copyright © 2017 Elsevier B.V.

Integration of air quality-related planning processes : report

International Nuclear Information System (INIS)

2004-05-01

Several communities in British Columbia have conducted air quality, greenhouse gas, or community energy management plans. This report explored the possibility of integrating 3 community-based air quality-related planning processes into a single process and evaluated the use of these 3 processes by local governments and First Nations in identifying and addressing air quality-related objectives, and determined to what extent they could be integrated to achieve planning objectives for air quality, greenhouse gas emissions, and energy supply and conservation. The lessons learned from 9 case studies in British Columbia were presented. The purpose of the case studies was to examine how communities handled emissions and energy related inventory and planning work, as well as their experiences with, or considerations for, an integrated process. The lessons were grouped under several key themes including organization and stakeholder involvement; messaging and focus; leadership/champions; and resources and capacity. The report also outlined a framework for an integrated planning process and provided recommendations regarding how an integrated or complementary process could be performed. A number of next steps were also offered for the provincial government to move the concept of an integrated process forward with the assistance of other partners. These included identifying the resources required to support communities engaging in an integrated process as well as discussing the series of options for provincial support with key stakeholders. refs., tabs., figs

An emphasis on preventive rather than reactive management is key to an efficient construction management operation. Development of contingency plans to deal with unexpected adverse conditions, e.g., brine pockets during mining operations, are an integral part of the management program to ensure project safety, quality, cost, schedule and environmental objectives are met. A viable quality assurance program with active management support will optimize management effectiveness in reaching project goals. With adequate planning and perceptive application of the proper management controls, Quality Assurance becomes an essential ingredient for efficiently managing a job because it has been built into the management system rather than being an uninvolved peripheral entity. 6 references, 3 figures

A process is described for fabricating thin plastic objects. It comprises the following successive operations: a supporting tray is moved into a pouring area; a succession of components of viscous composition in the predetermined shape corresponding to the objects to be produced is poured on to this supporting tray, the viscosity of the composition being such that these distinct components retain their poured shape when they are no longer supported on the supporting tray; the supporting tray bearing the distinct viscous composition components is then moved into a hardening area; the distinct viscous composition components are then irradiated in this hardening area so as to transform them into solid plastic objects. The supporting tray carrying the separate plastic objects, now solid, is withdrawn from the hardening area [fr

SUPPORT VECTOR MACHINE CLASSIFICATION OF OBJECT-BASED DATA FOR CROP MAPPING, USING MULTI-TEMPORAL LANDSAT IMAGERY

Full Text Available Crop mapping and time series analysis of agronomic cycles are critical for monitoring land use and land management practices, and analysing the issues of agro-environmental impacts and climate change. Multi-temporal Landsat data can be used to analyse decadal changes in cropping patterns at field level, owing to its medium spatial resolution and historical availability. This study attempts to develop robust remote sensing techniques, applicable across a large geographic extent, for state-wide mapping of cropping history in Queensland, Australia. In this context, traditional pixel-based classification was analysed in comparison with image object-based classification using advanced supervised machine-learning algorithms such as Support Vector Machine (SVM. For the Darling Downs region of southern Queensland we gathered a set of Landsat TM images from the 2010–2011 cropping season. Landsat data, along with the vegetation index images, were subjected to multiresolution segmentation to obtain polygon objects. Object-based methods enabled the analysis of aggregated sets of pixels, and exploited shape-related and textural variation, as well as spectral characteristics. SVM models were chosen after examining three shape-based parameters, twenty-three textural parameters and ten spectral parameters of the objects. We found that the object-based methods were superior to the pixel-based methods for classifying 4 major landuse/land cover classes, considering the complexities of within field spectral heterogeneity and spectral mixing. Comparative analysis clearly revealed that higher overall classification accuracy (95% was observed in the object-based SVM compared with that of traditional pixel-based classification (89% using maximum likelihood classifier (MLC. Object-based classification also resulted speckle-free images. Further, object-based SVM models were used to classify different broadacre crop types for summer and winter seasons. The influence of

Several so-called casting indices are available for objective evaluation of plaster cast quality. The present study sought to investigate four of these indices (gap index, padding index, Canterbury index, and three-point index) as compared to a reference standard (cast index) for evaluation of plaster cast quality after closed reduction of pediatric displaced distal forearm fractures. Forty-three radiographs from patients with displaced distal forearm fractures requiring manipulation were reviewed. Accuracy, sensitivity, specificity, false-positive probability, false-negative probability, positive predictive value, negative predictive value, positive likelihood ratio, and negative likelihood ratio were calculated for each of the tested indices. Comparison among indices revealed diagnostic agreement in only 4.7% of cases. The strongest correlation with the cast index was found for the gap index, with a Spearman correlation coefficient of 0.94. The gap index also displayed the best agreement with the cast index, with both indices yielding the same result in 79.1% of assessments. When seeking to assess plaster cast quality, the cast index and gap index should be calculated; if both indices agree, a decision on quality can be made. If the cast and gap indices disagree, the padding index can be calculated as a tiebreaker, and the decision based on the most frequent of the three results. Calculation of the three-point index and Canterbury index appears unnecessary. Copyright © 2016 Elsevier Ltd. All rights reserved.
Psychological Support as a Factor of the Training Process Quality Improvement

Directory of Open Access Journals (Sweden)

2017-06-01

Full Text Available Supportive activities may be one of the ways of the training process optimization. Support involves both components of the training process, i.e. training and rest. The training support is aimed at the training load increase or at such orientation of the adaptation processes to meet the training goals as closely as possible. The different aims lay behind the methods that support the rest mechanisms. It is about increasing the peace of the regeneration and recovery processes. This term describes all activities aimed at restoring the full exercise capacity of the athlete after work. The psychological support of the training process can be one of the ways to minimize training disturbances and it should therefore be an essential part of the training process management in case of the top ranked athletes. To improve the psychological support system of the training process and to improve the system quality, it is necessary to analyze the current situation. That’s why, authors of the paper decided to ask the members of the Polish Olympic team competed at the 2016 Olympic Games in Rio de Janeiro on types of relaxation techniques they accepted and used before the competition. The relaxation techniques were deliberately limited to the pre-start relaxation techniques as the study was treated as a pilot study dedicated to the problem identification. Therefore, the authors of the paper formulated its aim, as the identification of the pre-start relaxation preferences of the Olympic team members. The following research questions were formulated to meet the aim of the study: • What types of the pre-start relaxation techniques are declared and accepted by the Olympians? • Could the preferred pre-start relaxation techniques be considered rational, planned, and consciously implemented? A written interview with an online questionnaire was used as a research method. The study was conducted before the 2016 Olympic Games in Rio de

Family caregivers play an important role in caring for cancer patients, but the impact of caregivers' unmet needs on the quality of end-of-life (EOL) care they deliver and on their workplace performance are less understood. We identified 1,662 family caregivers of cancer patients who had died at any of 17 hospitals in Korea during 2004. The caregivers answered a telephone questionnaire about needs that were not met when they delivered terminal cancer care and how those unmet their needs affected their workplace performance; they also answered the Quality Care Questionnaire-End of Life (QCQ-EOL). Compared with caregivers who did not have unmet needs, caregivers who had unmet needs for symptom management, financial support, or community support showed poorer QCQ-EOL scores (P < 0.01). Caregivers who had unmet needs for financial support (adjusted odds ratio (aOR) = 7.55; 95% confidential interval (CI) 3.80-15.00), psychosocial support (aOR = 6.24; 95% CI 2.95-13.05), symptom management (aOR = 3.21; 95% CI 2.26-4.54), community support (aOR = 3.82; 95% CI 2.38-6.11), or religious support (aOR = 4.55; 95% CI 1.84-11.26) were more likely to experience work limitations. Caregivers of patients receiving conventional hospital care were more likely to have unmet needs for symptom management (aOR = 1.21; 95% CI 1.00-1.47), psychosocial support (aOR = 1.99; 95% CI 1.37-2.88), and religious support (aOR = 1.73; 95% CI 1.08-2.78) than those of patients receiving palliative hospice care. Caregivers' unmet needs negatively affected both the quality of EOL care they delivered and their workplace performance. More investment in caregiver support and public policies that meet caregiver needs are needed, and hospice use should be encouraged.

Monitoring water quality changes in lakes, reservoirs, estuaries, and coastal waters is critical in response to the needs for sustainable development. This study develops a remote sensing-based multiscale modeling system by integrating multi-sensor satellite data merging and image reconstruction algorithms in support of feature extraction with machine learning leading to automate continuous water quality monitoring in environmentally sensitive regions. This new Earth observation platform, termed "cross-mission data merging and image reconstruction with machine learning" (CDMIM), is capable of merging multiple satellite imageries to provide daily water quality monitoring through a series of image processing, enhancement, reconstruction, and data mining/machine learning techniques. Two existing key algorithms, including Spectral Information Adaptation and Synthesis Scheme (SIASS) and SMart Information Reconstruction (SMIR), are highlighted to support feature extraction and content-based mapping. Whereas SIASS can support various data merging efforts to merge images collected from cross-mission satellite sensors, SMIR can overcome data gaps by reconstructing the information of value-missing pixels due to impacts such as cloud obstruction. Practical implementation of CDMIM was assessed by predicting the water quality over seasons in terms of the concentrations of nutrients and chlorophyll-a, as well as water clarity in Lake Nicaragua, providing synergistic efforts to better monitor the aquatic environment and offer insightful lake watershed management strategies.

Health registries are commonly used in medicine to support public health activities and are increasingly used in quality improvement (QI) initiatives. Illustrations of dental registries and their QI applications are lacking. Within dentistry, caries risk assessment implementation and documentation are vital to optimal patient care. The purpose of this article is to describe the processes used to develop a caries risk assessment registry as a QI initiative to support clinical caries risk assessment, caries prevention, and disease management for children. Developmental steps reflected Agency for Healthcare Research and Quality recommendations for planning QI registries and included engaging "champions," defining the project, identifying registry features, defining performance dashboard indicators, and pilot testing with participant feedback. We followed Standards for Quality Improvement Reporting Excellence guidelines. Registry eligibility is patients aged 0-17 years. QI tools include prompts to register eligible patients; decision support tools grounded in evidence-based guidelines; and performance dashboard reports delivered at the provider and aggregated levels at regular intervals. The registry was successfully piloted in two practices with documented caries risk assessment increasing from 57 percent to 92 percent and positive feedback regarding the potential to improve dental practice patient centeredness, patient engagement and education, and quality of care. The caries risk assessment registry demonstrates how dental registries may be used in QI efforts to promote joint patient and provider engagement, foster shared decision making, and systematically collect patient information to generate timely and actionable data to improve care quality and patient outcomes at the individual and population levels. © 2017 American Association of Public Health Dentistry.

This article describes the development and implementations of a novel software platform that supports real-time, science-based policy making on air quality through a user-friendly interface. The software, RSM-VAT, uses a response surface modeling (RSM) methodology and serves as a visualization and analysis tool (VAT) for three-dimensional air quality data obtained by atmospheric models. The software features a number of powerful and intuitive data visualization functions for illustrating the complex nonlinear relationship between emission reductions and air quality benefits. The case study of contiguous U.S. demonstrates that the enhanced RSM-VAT is capable of reproducing the air quality model results with Normalized Mean Bias quality policy making in near real time.

Unmanned aerial vehicles (UAV) are increasingly investigated with regard to their potential to create and update (cadastral) maps. UAVs provide a flexible and low-cost platform for high-resolution data, from which object outlines can be accurately delineated. This delineation could be automated with image analysis methods to improve existing mapping procedures that are cost, time and labor intensive and of little reproducibility. This study investigates a superpixel approach, namely simple linear iterative clustering (SLIC), in terms of its applicability to UAV data. The approach is investigated in terms of its applicability to high-resolution UAV orthoimages and in terms of its ability to delineate object outlines of roads and roofs. Results show that the approach is applicable to UAV orthoimages of 0.05 m GSD and extents of 100 million and 400 million pixels. Further, the approach delineates the objects with the high accuracy provided by the UAV orthoimages at completeness rates of up to 64 %. The approach is not suitable as a standalone approach for object delineation. However, it shows high potential for a combination with further methods that delineate objects at higher correctness rates in exchange of a lower localization quality. This study provides a basis for future work that will focus on the incorporation of multiple methods for an interactive, comprehensive and accurate object delineation from UAV data. This aims to support numerous application fields such as topographic and cadastral mapping.

OBJECTIVE: This study examines the relationships among organizational culture, quality improvement processes and selected outcomes for a sample of up to 61 U. S. hospitals. DATA SOURCES AND STUDY SETTING: Primary data were collected from 61 U. S. hospitals (located primarily in the midwest and the west) on measures related to continuous quality improvement/total quality management (CQI/TQM), organizational culture, implementation approaches, and degree of quality improvement implementation based on the Baldrige Award criteria. These data were combined with independently collected data on perceived impact and objective measures of clinical efficiency (i.e., charges and length of stay) for six clinical conditions. STUDY DESIGN: The study involved cross-sectional examination of the named relationships. DATA COLLECTION/EXTRACTION METHODS: Reliable and valid scales for the organizational culture and quality improvement implementation measures were developed based on responses from over 7,000 individuals across the 61 hospitals with an overall completion rate of 72 percent. Independent data on perceived impact were collected from a national survey and independent data on clinical efficiency from a companion study of managed care. PRINCIPAL FINDINGS: A participative, flexible, risk-taking organizational culture was significantly related to quality improvement implementation. Quality improvement implementation, in turn, was positively associated with greater perceived patient outcomes and human resource development. Larger-size hospitals experienced lower clinical efficiency with regard to higher charges and higher length of stay, due in part to having more bureaucratic and hierarchical cultures that serve as a barrier to quality improvement implementation. CONCLUSIONS: What really matters is whether or not a hospital has a culture that supports quality improvement work and an approach that encourages flexible implementation. Larger-size hospitals face more difficult

In order to save and control the processes and quality of medical services, a suitable steering system of all relevant documents is essential from the point of view of clinical quality management. Systems supporting an automated steering system of documents are called document management systems (DMS), and they also enter the healthcare sector. The use of DMS in the German healthcare sector has hardly been investigated so far. To close this knowledge gap, interviews were carried out with German university hospitals over a six-month period and subjected to a qualitative content analysis according to Mayring. In total, 25 university hospitals agreed to participate in this study, 19 of which have been working with a digital DMS for about six years on average. There was a great variety among the IT systems used. Document management and usability of the DMS as well as its integration into existing IT structures were key decision-making criteria for the selection of a digital DMS. In general, the long-term usability of the DMS is supported by regular evaluation of one's own requirements for the system, administration and training programs. In addition, DMS have a positive effect on patient safety and the quality of medical care. Copyright © 2018. Published by Elsevier GmbH.

Up to 74% of patients with heart failure report poor sleep in Taiwan. Poor symptom management or sleep hygiene may affect patients' sleep quality. An effective educational programme was important to improve patients' sleep quality and psychological distress. However, research related to sleep disturbance in patients with heart failure is limited in Taiwan. To examine the effects of a tailored educational supportive care programme on sleep disturbance and psychological distress in patients with heart failure. randomised controlled trial. Eighty-four patients with heart failure were recruited from an outpatient department of a medical centre in Taipei, Taiwan. Patients were randomly assigned to the intervention group (n=43) or the control group (n=41). Patients in the intervention group received a 12-week tailored educational supportive care programme including individualised education on sleep hygiene, self-care, emotional support through a monthly nursing visit at home, and telephone follow-up counselling every 2 weeks. The control group received routine nursing care. Data were collected at baseline, the 4th, 8th, and 12th weeks after patients' enrollment. Outcome measures included sleep quality, daytime sleepiness, anxiety, and depression. The intervention group exhibited significant improvement in the level of sleep quality and daytime sleepiness after 12 weeks of the supportive nursing care programme, whereas the control group exhibited no significant differences. Anxiety and depression scores were increased significantly in the control group at the 12th week (p.05). Compared with the control group, the intervention group had significantly greater improvement in sleep quality (β=-2.22, pquality and psychological distress in patients with heart failure. We suggested that this supportive nursing care programme should be applied to clinical practice in cardiovascular nursing. Copyright © 2016 Elsevier Ltd. All rights reserved.

It is well known that cancer patients' perception of social support is associated with their depressive symptoms and health-related quality of life. However, there have been little studies that compared the variates of cancer patients with the general population. We sought to compare differences in the level of perceived social support and the impact of perceived social support on depressive symptoms and health-related quality of life between cancer survivors and the general population. Data were collected from 1818 cancer patients treated at the National Cancer Center and regional cancer centers in South Korea. The control group of the general population was composed of 2000 individuals without cancer from community. Cancer patients reported significantly higher level of perceived social support than the general population, while they reported lower health-related quality of life and were more susceptible to depression. The positive associations of higher perceived social support with lower depressive symptoms, as well as with higher health-related quality of life, were stronger among cancer patients than among the general population. The interaction effect suggests that the impact of social support would be stronger among cancer patients than the general public. Thus, it would be beneficial to pay attention to providing social support to cancer patients, particularly to those who are more vulnerable. Furthermore, investigation of the most effective and efficient methods to deliver social support interventions would be worthwhile. © The Author 2017. Published by Oxford University Press.

The objective was to explore the relationships among cognitive appraisals of prostate cancer (challenge, threat, and harm/loss), social comparisons, and quality of life in men previously diagnosed. Design, Sample, & Methods: Men who had participated in prostate cancer support groups completed a cross-sectional questionnaire (N = 189). Multivariable linear regression was used to evaluate social comparisons as mediators of quality of life while controlling for uncertainty and optimism. Positive and negative social comparisons were parallel mediators of the relationships between challenge or threat appraisals and quality of life, while only negative social comparisons mediated the relationship between harm/loss appraisals and quality of life. These findings demonstrate the importance of social comparisons in accounting for the effect of cognitive appraisals of prostate cancer on quality of life among men in support groups. Implications for Psychosocial Providers: Interventions to improve quality of life could address reduction of maladaptive comparisons, a strategy that could be tailored based on the patient's appraisal of prostate cancer.

Online monitoring and water quality analysis of lakes are urgently needed. A feasible and effective approach is to use a Wireless Sensor Network (WSN). Lake water environments, like other real world environments, present many changing and unpredictable situations. To ensure flexibility in such an environment, the WSN node has to be prepared to deal with varying situations. This paper presents a WSN self-configuration approach for lake water quality monitoring. The approach is based on the integration of a semantic framework, where a reasoner can make decisions on the configuration of WSN services. We present a WSN ontology and the relevant water quality monitoring context information, which considers its suitability in a pervasive computing environment. We also propose a rule-based reasoning engine that is used to conduct decision support through reasoning techniques and context-awareness. To evaluate the approach, we conduct usability experiments and performance benchmarks.

Effects and interactions of calpain-system tenderness gene markers on objective meat quality traits of Brahman (Bos indicus) cattle were quantified within 2 concurrent experiments at different locations. Cattle were selected for study from commercial and research herds at weaning based on their genotype for calpastatin (CAST) and calpain 3 (CAPN3) gene markers for beef tenderness. Gene marker status for mu-calpain (CAPN1-4751 and CAPN1-316) was also determined for inclusion in statistical analyses. Eighty-two heifer and 82 castrated male cattle with 0 or 2 favorable alleles for CAST and CAPN3 were studied in New South Wales (NSW), and 143 castrated male cattle with 0, 1, or 2 favorable alleles for CAST and CAPN3 were studied in Western Australia (WA). The cattle were backgrounded for 6 to 8 mo and grain-fed for 117 d (NSW) or 80 d (WA) before slaughter. One-half the cattle in each experiment were implanted with a hormonal growth promotant during feedlotting. One side of each carcass was suspended from the Achilles tendon (AT) and the other from the pelvis (tenderstretch). The M. longissimus lumborum from both sides and the M. semitendinosus from the AT side were collected; then samples of each were aged at 1 degrees C for 1 or 7 d. Favorable alleles for one or more markers reduced shear force, with little effect on other meat quality traits. The size of effects of individual markers varied with site, muscle, method of carcass suspension, and aging period. Individual marker effects were additive as evident in cattle with 4 favorable alleles for CAST and CAPN3 markers, which had shear force reductions of 12.2 N (P 0.05) of interactions between the gene markers, or between the hormonal growth promotant and gene markers for any meat quality traits. This study provides further evidence that selection based on the CAST or CAPN3 gene markers improves meat tenderness in Brahman cattle, with little if any detrimental effects on other meat quality traits. The CAPN1-4751 gene

Full Text Available Objectives: to develop an integrated computer software application for specialized nutritional support, integrated in the electronic clinical record, which detects automatically and early those undernourished patients or at risk of developing undernourishment, determining points of opportunity for improvement and evaluation of the results. Methods: the quality standards published by the Nutrition Work Group of the Spanish Society of Hospital Pharmacy (SEFH and the recommendations by the Pharmacy Group of the Spanish Society of Parenteral and Enteral Nutrition (SENPE have been taken into account. According to these quality standards, the nutritional support has to include the following healthcare stages or sub-processes: nutritional screening, nutritional assessment, plan for nutritional care, prescription, preparation and administration. Results: this software allows to conduct, in an automated way, a specific nutritional assessment for those patients with nutritional risk, implementing, if necessary, a nutritional treatment plan, conducting follow-up and traceability of outcomes derived from the implementation of improvement actions, and quantifying to what extent our practice is close to the established standard. Conclusions: this software allows to standardize the specialized nutritional support from a multidisciplinary point of view, introducing the concept of quality control per processes, and including patient as the main customer

Severe brain injuries have long-term consequences on functional status and psychosocial functioning. Family life can be greatly influenced as well, and features of high caregiver burden can emerge. Although the data on caregivers' distress are constantly increasing, less information is available about the role of family functioning. Thirty caregivers of hospitalised patients with severe brain injuries received questionnaires for the evaluation of caregiver burden, family functioning and perceived social support. A semi-structured interview was performed for the evaluation of quality of life. Family cohesion and adaptability positively correlated with caregivers' quality of life and perceived social support. Partner caregivers' scores were significantly higher on the time-dependent burden than those of sons and daughters, whereas the latter scored higher on the emotional burden.
A resource allocation model to support efficient air quality management in South Africa

2009-06-01

Full Text Available Research into management interventions that create the required enabling environment for growth and development in South Africa are both timely and appropriate. In the research reported in this paper, the authors investigated the level of efficiency of the Air Quality Units within the three spheres of government viz. National, Provincial, and Local Departments of Environmental Management in South Africa, with the view to develop a resource allocation model. The inputs to the model were calculated from the actual man-hours spent on twelve selected activities relating to project management, knowledge management and change management. The outputs assessed were aligned to the requirements of the mandates of these Departments. Several models were explored using multiple regressions and stepwise techniques. The model that best explained the efficiency of the organisations from the input data was selected. Logistic regression analysis was identified as the most appropriate tool. This model is used to predict the required resources per Air Quality Unit in the different spheres of government in an attempt at supporting and empowering the air quality regime to achieve improved output efficiency.
Evaluation of features to support safety and quality in general practice clinical software

Science.gov (United States)

2011-01-01

Background Electronic prescribing is now the norm in many countries. We wished to find out if clinical software systems used by general practitioners in Australia include features (functional capabilities and other characteristics) that facilitate improved patient safety and care, with a focus on quality use of medicines. Methods Seven clinical software systems used in general practice were evaluated. Fifty software features that were previously rated as likely to have a high impact on safety and/or quality of care in general practice were tested and are reported here. Results The range of results for the implementation of 50 features across the 7 clinical software systems was as follows: 17-31 features (34-62%) were fully implemented, 9-13 (18-26%) partially implemented, and 9-20 (18-40%) not implemented. Key findings included: Access to evidence based drug and therapeutic information was limited. Decision support for prescribing was available but varied markedly between systems. During prescribing there was potential for medicine mis-selection in some systems, and linking a medicine with its indication was optional. The definition of 'current medicines' versus 'past medicines' was not always clear. There were limited resources for patients, and some medicines lists for patients were suboptimal. Results were provided to the software vendors, who were keen to improve their systems. Conclusions The clinical systems tested lack some of the features expected to support patient safety and quality of care. Standards and certification for clinical software would ensure that safety features are present and that there is a minimum level of clinical functionality that clinicians could expect to find in any system.
Cognitive and social cognitive predictors of change in objective versus subjective quality-of-life in rehabilitation for schizophrenia.

Kurtz, Matthew M; Bronfeld, Melanie; Rose, Jennifer

2012-12-30

A small but growing body of work has studied the role of cognitive skills in predicting response to integrated programs of rehabilitation in schizophrenia. No studies however, have directly compared the roles and interrelationships of cognition, social cognition and other disease factors in predicting improvements in the separate domains of objective quality-of-life (QOL) and subjective satisfaction with life (SWL) in response to rehabilitation in schizophrenia. Forty-four outpatients with schizophrenia were administered measures of cognition, social cognition, and symptoms at entry to a psychosocial and cognitive rehabilitation program. Change in objective QOL and subjective SWL before and after treatment were measured as outcome variables. Cognitive measures of verbal memory and social cognitive measures of facial affect recognition were linked to improvements in objective QOL, while verbal memory and crystallized verbal skill was linked to improvements in SWL. Facial affect recognition partially mediated the relationship between verbal memory and improvements in objective QOL. The implications of these findings for understanding interrelationships between cognition and social cognition and their role in predicting change in different domains of outcome as a function of behavioral treatment are discussed.

Full Text Available Abstract Objective The quality of external chest compressions (ECC is of primary importance within basic life support (BLS. Recent guidelines delineate the so-called 4“-step approach” for teaching practical skills within resuscitation training guided by a certified instructor. The objective of this study was to evaluate whether a “media-supported 4-step approach” for BLS training leads to equal practical performance compared to the standard 4-step approach. Materials and methods After baseline testing, 220 laypersons were either trained using the widely accepted method for resuscitation training (4-step approach or using a newly created “media-supported 4-step approach”, both of equal duration. In this approach, steps 1 and 2 were ensured via a standardised self-produced podcast, which included all of the information regarding the BLS algorithm and resuscitation skills. Participants were tested on manikins in the same mock cardiac arrest single-rescuer scenario prior to intervention, after one week and after six months with respect to ECC-performance, and participants were surveyed about the approach. Results Participants (age 23 ± 11, 69% female reached comparable practical ECC performances in both groups, with no statistical difference. Even after six months, there was no difference detected in the quality of the initial assessment algorithm or delay concerning initiation of CPR. Overall, at least 99% of the intervention group (n = 99; mean 1.5 ± 0.8; 6-point Likert scale: 1 = completely agree, 6 = completely disagree agreed that the video provided an adequate introduction to BLS skills. Conclusions The “media-supported 4-step approach” leads to comparable practical ECC-performance compared to standard teaching, even with respect to retention of skills. Therefore, this approach could be useful in special educational settings where, for example, instructors’ resources are sparse or large-group sessions

Background : Quality improvement initiatives can help nursing homes strengthen psychosocial work environments. The aim of the present study was to examine the association between supportive psychosocial work environment, and professional and organizational characteristics regarding quality improvement initiatives in dementia care. Methods : A paper questionnaire survey was administered to a convenience sample of 365 professional caregivers in 12 special nursing homes in Japan. Psychosocial work environment was assessed using the Social Capital and Ethical Climate at the Workplace Scale to calculate a score of social capital in the workplace, ethical leadership, and exclusive workplace climate. Variables for quality improvement initiatives included type of home (unit-type or traditional), presence of additional benefit for dementia care, and professionalism in dementia care among caregivers evaluated using the Japanese version of the Sense of Competence in Dementia Care Staff Scale. Results : Elevated professionalism and unit-type home were significantly associated with high social capital, strong ethical leadership, and low exclusive workplace climate. The presence of dementia care benefit was not associated with any subscale of psychosocial work environment. Conclusions : Quality improvement initiatives to foster supportive psychosocial work environment should enhance professionalism in dementia care with unit-based team building of professional caregivers in special nursing homes.

Full Text Available As medication experts, pharmacists are key members of the patient’s healthcare team. Pharmacists must maintain their competence to practice to remain responsive to the increasingly complex healthcare sector. This paper seeks to determine how competence training for pharmacists may enhance quality in their professional development. Results of two separately administered surveys (2012 and 2013 were compared to examine the reported continued professional development (CPD practices of Australian pharmacists. Examination of results from both studies enabled a focus on how the competency standards inform CPD practice.In the survey administered in 2012, 91% (n = 253/278 pharmacists reported that they knew their current registration requirements. However, in the survey administered in 2013, only 43% (n = 46/107 reported utilization of the National Competency Standards Framework for Pharmacists in Australia (NCS to self-asses their practice as part of their annual re-registration requirements. Fewer, 23% (n = 25/107, used the NCS to plan their CPD. This may be symptomatic of poor familiarity with the NCS, uncertainty around undertaking self-directed learning as part of a structured learning plan and/or misunderstandings around what CPD should include. This is supported by thematic analysis of pharmacists’ social media comments. Initial and ongoing competence training to support meaningful CPD requires urgent attention in Australia. The competence (knowledge, skills and attributes required to engage in meaningful CPD practice should be introduced and developed prior to entry into practice; other countries may find they are in a similar position.
Multi-objective calibration of a reservoir model: aggregation and non-dominated sorting approaches

Science.gov (United States)

Huang, Y.

Numerical reservoir models can be helpful tools for water resource management. These models are generally calibrated against historical measurement data made in reservoirs. In this study, two methods are proposed for the multi-objective calibration of such models: aggregation and non-dominated sorting methods. Both methods use a hybrid genetic algorithm as an optimization engine and are different in fitness assignment. In the aggregation method, a weighted sum of scaled simulation errors is designed as an overall objective function to measure the fitness of solutions (i.e. parameter values). The contribution of this study to the aggregation method is the correlation analysis and its implication to the choice of weight factors. In the non-dominated sorting method, a novel method based on non-dominated sorting and the method of minimal distance is used to calculate the dummy fitness of solutions. The proposed methods are illustrated using a water quality model that was set up to simulate the water quality of Pepacton Reservoir, which is located to the north of New York City and is used for water supply of city. The study also compares the aggregation and the non-dominated sorting methods. The purpose of this comparison is not to evaluate the pros and cons between the two methods but to determine whether the parameter values, objective function values (simulation errors) and simulated results obtained are significantly different with each other. The final results (objective function values) from the two methods are good compromise between all objective functions, and none of these results are the worst for any objective function. The calibrated model provides an overall good performance and the simulated results with the calibrated parameter values match the observed data better than the un-calibrated parameters, which supports and justifies the use of multi-objective calibration. The results achieved in this study can be very useful for the calibration of water

In the recent past, we have seen an increase in the outsourcing of bioanalysis in pharmaceutical companies in support of their drug development pipeline. This trend is largely driven by the effort to reduce internal cost, especially in support of late-stage pipeline assets where established bioanalytical assays are used to analyze a large volume of samples. This article will highlight our perspective of how bioanalytical laboratories within pharmaceutical companies can be developed into the best partner in the advancement of drug development pipelines with high-quality support at competitive cost.

Full Text Available Background Bipolar disorder is a chronic condition that affects the functioning of its carriers in many different ways, even when treated properly. Therefore, it’s also important to identify the psychosocial aspects that could contribute to an improvement of this population’s quality of life.Objective Carry out a literature review on the role of social support in cases of bipolar disorder.Method A research on the following online databases PubMed, Lilacs and SciELO was conducted by using the keywords “social support” or “social networks” and “mood disorders” or “bipolar disorder” or “affective disorder,” with no defined timeline.Results Only 13 studies concerning the topic of social support and BD were found in the search for related articles. Generally speaking, the results show low rates of social support for BD patients.Discussion Despite the growing interest in the overall functioning of patients with bipolar disorder, studies on social support are still rare. Besides, the existing studies on the subject use different methodologies, making it difficult to establish data comparisons.
