    1996-12-01

    Full Text Available Much research has been conducted regarding how reference librarians can evaluate and improve the quality of the answers they provide to users' inquiries. There has been considerably less discussion, however, concerning how to improve the quality of the delivery of those answers, and to upgrade the overall quality of reference services as a whole. Suggestions for improving the quality of service contained within the business literature may be applied to improve library services as well. In this paper the use of Quality Function Deployment (QFD as a tool for improving reference services quality is explored and an adapted framework referred to as service quality function deployment is proposed.

    1990-11-01

    The goal of the Advanced Launch System (ALS) is a more efficient launch capability that provides a highly reliable and operable system at substantially lower cost than current launch systems. Total Quality Management (TQM) principles are being emphasized throughout the ALS program. A continuous improvement philosophy is directed toward satisfying users' and customer's requirements in terms of quality, performance, schedule, and cost. Quality Function Deployment (QFD) is interpreted as the voice of the customer (or user), and it is an important planning tool in translating these requirements throughout the whole process of design, development, manufacture, and operations. This report explores the application of QFD methodology to launch operations, including the modification and addition of events (operations planning) in the engineering development cycle, and presents an informal status of study results to date. QFD is a technique for systematically analyzing the customer's (Space Command) perceptions of what constitutes a highly reliable and operable system and functionally breaking down those attributes to identify the critical characteristics that determine an efficient launch system capability. In applying the principle of QFD, a series of matrices or charts are developed with emphasis on the one commonly known as the House of Quality (because of its roof-like format), which identifies and translates the most critical information.

  8. A hybrid fuzzy MCDM approach to maintenance Quality Function Deployment

    Directory of Open Access Journals (Sweden)

    Davy George Valavi

    2015-01-01

    Full Text Available Maintenance Quality Function Deployment (MQFD is a model, which enhances the synergic power of Quality Function Deployment (QFD and Total Productive Maintenance (TPM. One of the crucial and important steps during the implementation of MQFD is the determination of the importance or weightages of the critical factors (CF and sub factors (SF. The CFs and SFs have to be compared precisely for the successful implementation of MQFD. The crisp pair-wise comparison in the conventional Analytical Hierarchy Process (AHP may be insufficient to determine the degree of weightage of CFs and SFs where vagueness and uncetainties are associated. In this paper, a modification of AHP based MQFD by incorporating fuzzy operations is proposed, which can improve the accuracy of determination of the weightages. A case study showing the applicability of this method is illustrated in this paper.

    Full Text Available Background: Today’s healthcare organizations are challenged by pressures to meet growing population demands and enhance community health through improving service quality. Quality function deployment is one of the widely-used customerdriven approaches for health services development. In the current study, quality function deployment is used to improve the quality of chemotherapy unit services. Methods: First, we identified chemotherapy outpatient unit patients as chemotherapy unit customers. Then, the Delphi technique and component factor analysis with orthogonal rotation was employed to determine their expectations. Thereafter, data envelopment analysis was performed to specify user priorities. We determined the relationships between patients’ expectations and service elements through expert group consensus using the Delphi method and the relationships between service elements by Pearson correlation. Finally, simple and compound priorities of the service elements were derived by matrix calculation. Results: Chemotherapy unit patients had four main expectations: access, suitable hotel services, satisfactory and effective relationships, and clinical services. The chemotherapy unit has six key service elements of equipment, materials, human resources, physical space, basic facilities, and communication and training. There were four-level relationships between the patients’ expectations and service elements, with mostly significant correlations between service elements. According to the findings, the functional group of basic facilities was the most critical factor, followed by materials. Conclusion: The findings of the current study can be a general guideline as well as a scientific, structured framework for chemotherapy unit decision makers in order to improve chemotherapy unit services.

  10. Product design on the basis of fuzzy quality function deployment

    2008-01-01

    In the implementation of quality function deployment (QFD), the determination of the target values of engineering characteristics is a complex decision process with multiple variables and multiple objectives that should trade off, and optimize all kinds of conflicts and constraints. A fuzzy linear programming model (FLP) is proposed. On the basis of the inherent fuzziness of QFD system, triangular fuzzy numbers are used to represent all the relationships and correlations, and then, the functional relationships between the customer needs and engineering characteristics and the functional correlations among the engineering characteristics are determined with the information in the house of quality (HoQ) fully used. The fuzzy linear programming (FLP) model aims to find the optimal target values of the engineering characteristics to maximize the customer satisfaction. Finally, the proposed method is illustrated by a numerical example.

  11. Performance analysis, quality function deployment and structured methods

    Science.gov (United States)

    Maier, M. W.

    Quality function deployment, (QFD), an approach to synthesizing several elements of system modeling and design into a single unit, is presented. Behavioral, physical, and performance modeling are usually considered as separate aspects of system design without explicit linkages. Structured methodologies have developed linkages between behavioral and physical models before, but have not considered the integration of performance models. QFD integrates performance models with traditional structured models. In this method, performance requirements such as cost, weight, and detection range are partitioned into matrices. Partitioning is done by developing a performance model, preferably quantitative, for each requirement. The parameters of the model become the engineering objectives in a QFD analysis and the models are embedded in a spreadsheet version of the traditional QFD matrices. The performance model and its parameters are used to derive part of the functional model by recognizing that a given performance model implies some structure to the functionality of the system.

  12. Applying fuzzy analytic network process in quality function deployment model

    Full Text Available In this paper, we propose an empirical study of QFD implementation when fuzzy numbers are used to handle the uncertainty associated with different components of the proposed model. We implement fuzzy analytical network to find the relative importance of various criteria and using fuzzy numbers we calculate the relative importance of these factors. The proposed model of this paper uses fuzzy matrix and house of quality to study the products development in QFD and also the second phase i.e. part deployment. In most researches, the primary objective is only on CRs to implement the quality function deployment and some other criteria such as production costs, manufacturing costs etc were disregarded. The results of using fuzzy analysis network process based on the QFD model in Daroupat packaging company to develop PVDC show that the most important indexes are being waterproof, resistant pill packages, and production cost. In addition, the PVDC coating is the most important index in terms of company experts’ point of view.

    2014-09-01

    The first-hand needs and demands of laypersons are not always considered when safety promotion programmes are being developed. We compared focal areas for interventions identified from residents' statements of safety needs with focal areas for interventions identified by local government professionals in a Swedish urban community certified by the international Safe Community movement supported by the World Health Organization. Quantitative and qualitative data on self-expressed safety needs from 787 housing residents were transformed into an intervention design, using the quality function deployment (QFD) technique and compared with the safety intervention programme developed by professionals at the municipality administrative office. The outcome of the comparison was investigated with regard to implications for the Safe Community movement. The QFD analysis identified the initiation and maintenance of social integrative processes in housing areas as the most highly prioritized interventions among the residents, but failed to highlight the safety needs of several vulnerable groups (the elderly, infants and persons with disabilities). The intervention programme designed by the public health professionals did not address the social integrative processes, but it did highlight the vulnerable groups. This study indicates that the QFD technique is suitable for providing residential safety promotion efforts with a quality orientation from the layperson's perspective. Views of public health professionals have to be included to ascertain that the needs of socially deprived residents are adequately taken into account. QFD can augment the methodological toolbox for safety promotion programmes, including interventions in residential areas.

    1992-01-01

    The final report of the 1992 NASA/ASEE Summer Faculty Fellowship at the Space Exploration Initiative Office (SEIO) in Langley Research Center is presented. Quality Function Deployment (QFD) is a process, focused on facilitating the integration of the customer's voice in the design and development of a product or service. Various input, in the form of judgements and evaluations, are required during the QFD analyses. All the input variables in these analyses are treated as numeric variables. The purpose of the research was to investigate how QFD analyses can be performed when some or all of the input variables are treated as linguistic variables with values expressed as fuzzy numbers. The reason for this consideration is that human judgement, perception, and cognition are often ambiguous and are better represented as fuzzy numbers. Two approaches for using fuzzy sets in QFD have been proposed. In both cases, all the input variables are considered as linguistic variables with values indicated as linguistic expressions. These expressions are then converted to fuzzy numbers. The difference between the two approaches is due to how the QFD computations are performed with these fuzzy numbers. In Approach 1, the fuzzy numbers are first converted to their equivalent crisp scores and then the QFD computations are performed using these crisp scores. As a result, the output of this approach are crisp numbers, similar to those in traditional QFD. In Approach 2, all the QFD computations are performed with the fuzzy numbers and the output are fuzzy numbers also. Both the approaches have been explained with the help of illustrative examples of QFD application. Approach 2 has also been applied in a QFD application exercise in SEIO, involving a 'mini moon rover' design. The mini moon rover is a proposed tele-operated vehicle that will traverse and perform various tasks, including autonomous operations, on the moon surface. The output of the moon rover application exercise is a

Up to now little quantization method suitable for aviation weapon systems innovation is presented. Base on the deep analysis and study on features of aviation weapon systems innovation and different innovation mode from the mass production, we have designed process model and quality chain model of aviation weapon systems innovation. Compared with the process model of large-scale innovation, the process models are more complex including many feedbacks and adding five steps: task decomposition, analysis of knowledge gap, accumulation of key knowledge, outsourcing selection, system integration. Meanwhile manufacturing process and R&D process are preformed simultaneously, and are involved in the process of module development. Technology application and diffusion are preformed with delivering the final innovation product to user. Quality function deployment and quality house are adopted to deal with the quality transfer among nodes. Quality demands of one node are converted into the technique features of another node in the quality house. We designed the top-down technique features transfer model and bottom-up demands transfer model to solve the quality transfer problems among nodes. At last an example is given to illustrate that this approach can accelerate to blaze the aviation weapon systems trails more than the existing methods and effectively reach quality management of aviation weapon systems innovation.

    As a result of today's globalized world and robust development of emerging markets, consumers are able to select from an endless number of products that are mostly similar in terms of design and properties, as well as equivalent in function and performance. The survival of businesses in a competitive ambience requires innovation, consumer loyalty, and products that are easily identifiable by consumers. Today's manufacturers have started to employ customer research instruments to survive in the highly industrialized world—for example, Conjoint Analysis, Design of Experiments and Semantic Design of Environment. However, this work only attempts to concentrate on Kansei Engineering and Quality Function Deployment. Kansei Engineering (KE) is deemed as the most appropriate method to link consumers' feelings, emotions or senses to the properties of a product because it translates people's impressions, interests, and feelings to the solutions of product design. Likewise, Quality Function Deployment (QFD) enables clearer interpretation of the needs of consumers, better concepts or products, and enhanced communication to internal operations that must then manufacture and deliver the product or services. The integration of both KE and QFD is believed possible, as many product manufacturers and businesses have started to utilize systematized methods to translate consumers' needs and wants into processes and products. Therefore, this work addresses areas of various integrations of KE and QFD processes in the industry, in an effort to assist an integration of KE and QFD. This work aims to provide evidence on the integration mechanism to enable successful incorporation of consumer's implicit feelings and demands into product quality improvement, and simultaneously providing an overview of both KE and QFD from the perspective of a novice.

    Quality function deployment (QFD) can provide a means of translating customer requirements (CRs) into engineering characteristics (ECs) for each stage of product development and production. The main objective of QFD-based product planning is to determine the target levels of ECs for a new product or service. QFD is a breakthrough tool which can effectively reduce the gap between CRs and a new product/service. Even though there are conflicts among some ECs, the objective of developing new product is to maximize the overall customer satisfaction. Therefore, there may be room for cooperation among ECs. A cooperative game framework combined with fuzzy set theory is developed to determine the target levels of the ECs in QFD. The key to develop the model is the formulation of the bargaining function. In the proposed methodology, the players are viewed as the membership functions of ECs to formulate the bargaining function. The solution for the proposed model is Pareto-optimal. An illustrated example is cited to demonstrate the application and performance of the proposed approach.

    2016-11-01

    Full Text Available Quality function deployment (QFD is a widely used quality system tool for translating customer requirements (CRs into the engineering design requirements (DRs of products or services. The conventional QFD analysis, however, has been criticized as having some limitations such as in the assessment of relationships between CRs and DRs, the determination of CR weights and the prioritization of DRs. This paper aims to develop a new hybrid group decision-making model based on hesitant 2-tuple linguistic term sets and an extended QUALIFLEX (qualitative flexible multiple criteria method approach for handling QFD problems with incomplete weight information. First, hesitant linguistic term sets are combined with interval 2-tuple linguistic variables to express various uncertainties in the assessment information of QFD team members. Borrowing the idea of grey relational analysis (GRA, a multiple objective optimization model is constructed to determine the relative weights of CRs. Then, an extended QUALIFLEX approach with an inclusion comparison method is suggested to determine the ranking of the DRs identified in QFD. Finally, an analysis of a market segment selection problem is conducted to demonstrate and validate the proposed QFD approach.

    Full Text Available Quality function deployment (QFD is one such extremely important quality management tool, which is useful in product design and development. Traditionally, QFD rates the design requirements (DRs with respect to customer requirements, and aggregates the rating to get relative importance score of DRs. An increasing number of studies emphasize on the need to incorporate additional factors, such as cost and environmental impact, while calculating the relative importance of DRs. However, there are different methodologies for driving the relative importance of DRs, when several additional factors are considered. TOPSIS (technique for order preferences by similarity to ideal solution is suggested for the purpose of the research. This research proposes new approach of TOPSIS for considering the rating of DRs with respect to CRs, and several additional factors, simultaneously. Proposed method is illustrated using by step-by-step procedure. The proposed methodology was applied for the Sanam Electronic Company in Iran.

    Malaysia as a developing country favor energy demand by years which created mainly from fossil fuel. Unfortunately, the action leads to significant increment in carbon dioxide (CO2) emission that causing the global warming. The most promising mitigation strategy is by deploying Carbon Capture and Storage (CCS) technology where mineral carbonation was identified as the safest method for permanent storage and does not require continuous monitoring. Accordingly, National Green Technology was launched in 2009 to support the growth of green technology development in Malaysia as a carbon mitigation strategy. Thus, this paper aims to propose the development of a conceptual eco-design for Low Energy Mechanical Milling (LEMM). The concept was proposed by using the Quality Function Deployment (QFD) tool with combination of sustainability determinants (DFS) namely economic, environmental and social which evaluated using Solidworks 2015 sustainability assessment. The results show the new product targets for LEMM in prior on energy consumption (MJ), selling price (MYR), material cost (MYR), carbon footprint (kg CO2) with weightage of 5.2, 4.2, 3.6 and 3.6 respectively. The implementation of DFS criteria into the QFD promote to reduce material used by 16%, 35% reduction of carbon footprint, 28% less energy consumption, 28% lower air acidification, 77% of water eutrophication declined and increased recyclability by 15%.

    Full Text Available Despite of the significant contribution of QFD for the construction of the theoretical framework for managing the development of new products and services, there is an embryonic implementation in the public sector. The purpose of this article is to analyze the application of the method in the context of public safety, and the study was delimited to the School Patrol in the Military Police of Minas Gerais. Action research was the research strategy chosen and qualitative and quantitative methods were used to collect and analyze data. The QFD method proved to be effective for: systematize a large set of internal and external corporate information, facilitating the subsequent planning of policing; promote a dynamic oriented and structured in encounters between police and the community; identify the needs of public school and prioritize activities policing which better fulfill these desires; and to understand the ability of service of a School Patrol Unit. Moreover, the police service has a unique set of characteristics that partially hindered planning service by QFD. This service does not have a specific market niche, being a service of law and not by purchase. Also relies on legal aspects and regulates behaviors, generating rejection. Although this particular nature, two factors favored the application of the method: the institutionalization of the philosophy of community policing in the organization and to familiarizing officers with management concepts and quality. The final conclusion is that the QFD method was presented as a promising tool for improving the quality of Brazilian public services.

    2012-01-01

    Full Text Available Quality function deployment (QFD is a customer-driven approach for product design and development. A QFD analysis process includes a series of subprocesses, such as determination of the importance of customer requirements (CRs, the correlation among engineering characteristics (ECs, and the relationship between CRs and ECs. Usually more than group of one decision makers are involved in the subprocesses to make the decision. In most decision making problems, they often provide their evaluation information in the linguistic form. Moreover, because of different knowledge, background, and discrimination ability, decision makers may express their linguistic preferences in multigranularity linguistic information. Therefore, an effective approach to deal with the multi-granularity linguistic information in QFD analysis process is highly needed. In this study, the QFD methodology is extended with 2-tuple linguistic representation model under multi-granularity linguistic environment. The extended QFD methodology can cope with multi-granularity linguistic evaluation information and avoid the loss of information. The applicability of the proposed approach is demonstrated with a numerical example.

    Abu-Assab, Samah; Baier, Daniel

    In this paper, we compare two product design approaches, quality function deployment (QFD) and conjoint analysis (CA), on the example of mobile phones for elderly people as a target group. Then, we compare between our results and the results from former similar comparisons, e.g., Pullman et al. (J Prod Innov Manage 19(5):354-364, 2002) and Katz (J Innov Manage 21:61-63, 2004). In this work, the same procedures and conditions are taken into consideration as that taken by Pullman et al. in their paper. They viewed the relation between the two methods: QFD and CA as a complementary one in which both should be simultaneously implemented since each provide feedback to the other. They concluded that CA is more efficient in reflecting the end-users’ present preferences for the product attributes, whereas QFD is definitely better in satisfying end-users’ needs from the developers’ point of view. Katz in his response from a practitioner’s point of view agreed with Pullman et al. However, he concluded that the two methods are better used sequentially and that QFD should precede conjoint analysis. We test these results in a market for elderly people.

    Quality function deployment (QFD) is a product development technique that translates customer requirements into activities for the development of products and services. This study utilizes QFD to identify American customer's requirements for bulgogi, a popular Korean dish among international customers, and how to fulfill those requirements. A customer survey and an expert opinion survey were conducted for US customers. The top five customer requirements for bulgogi were identified as taste, freshness, flavor, tenderness, and juiciness; ease of purchase was included in the place of tenderness after calculating the weight requirements. Eighteen engineering characteristics were developed, and a 'localization of bulgogi menu' is strongly related to the other characteristics as well. The results from the calculation of relative importance of engineering characteristics identified that the 'control of marinating time', 'localization of bulgogi menu', 'improvement of cooking and serving process', 'development of recipe by parts of beef', and 'use of various seasonings' were the highest contributors to the overall improvement of bulgogi. The relative importance of engineering characteristics, correlation, and technical difficulties are ranked and integrated to develop the most effective strategy. The findings are discussed relative to industry implications. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2007-01-01

    Full Text Available Six Sigma has been known to be a breakthrough business strategy to achieve customer satisfaction through defect reduction and cost optimization. A flawless product or service would, however, be of little value if it does not sell. Thus, it is of considerable importance to begin with the customer. Quality Function Deployment (QFD, as a customer-driven tool in Design for Six Sigma (DFSS toolset, can be regarded as one of the most powerful tools to serve this purpose. The success of QFD use relies heavily on the accuracy of the primary input, that is, the Voice of the Customer (VOC. To better identify and obtain more accurate VOC, the use of Kano Model in QFD has been incorporated in the literature. Unfortunately, the dynamics of Kano Model, such as the fact that what now delights the customer will become an expected need in the future is often oversimplified and has not been adequately addressed. The aim of this paper is to shed some light to Kano Model dynamics modeling by providing a quantitative technique which is based on compositional data analysis. It is expected that a timely update of customer needs data may serve as a useful indicator to monitor the progress of how well a company satisfies its customer over time, and at the same time provide a ground for formulating the next strategies as to enable the company to respond differently and continuously over time of its operations. To give some practical insights, an illustrative example is provided.

    Full Text Available This study aims to present the differences between the use of QFD and its association with CVCA tool in the development of a CPM device for elbow and forearm rehabilitation. To achieve this goal, the study was divided into three steps. The development of a conceptual model that integrates the proposed CVCA + QFD tool for application in the health device development was done in the first step. The second step consisted of applying the proposed model, referring to the QFD method using 8 matrixes: quality matrix, product, characteristics of the parts, process, process parameters, human resources, infrastructure and costs matrix. The proposed conceptual model was employed fully in the third step, allowing the comparison between the methods. The results enabled to identify a discrepancy between the critical costumers in the use of mentioned methods. Customers were limited to the direct and indirect users in the QFD application: the patient, physician and physical therapist. This list got a considerable increase when CVCA was applied: the clinical engineering, product engineering, process and reliability engineering, project and product managers, financial sector, quality system and regulatory issues. These results show the importance of analyzing the supply chain systemically in order to consider all stakeholders to the CPM device development.

    In this paper, an integrated methodology for Quality Function Deployment (QFD) and a 0-1 knapsack model is proposed for occupational safety and health as a systems thinking approach. The House of Quality (HoQ) in QFD methodology is a systematic tool to consider the inter-relationships between two factors. In this paper, three HoQs are used to consider the interrelationships between tasks and hazards, hazards and events, and events and preventive/protective measures. The final priority weights of events are defined by considering their project-specific preliminary weights, probability of occurrence, and effects on the victim and the company. The priority weights of the preventive/protective measures obtained in the last HoQ are fed into a 0-1 knapsack model for the investment decision. Then, the selected preventive/protective measures can be adapted to the task design. The proposed step-by-step methodology can be applied to any stage of a project to design the workplace for occupational safety and health, and continuous improvement for safety is endorsed by the closed loop characteristic of the integrated methodology.

    2013-12-01

    Semantic descriptions of observed properties and associated units of measure are fundamental to understanding of environmental observations, including groundwater, surface water and marine water quality. Semantic descriptions can be captured in machine-readable ontologies and vocabularies, thus providing support for the annotation of observation values from the disparate data sources with appropriate and accurate metadata, which is critical for achieving semantic interoperability. However, current stand-alone water quality vocabularies provide limited support for cross-system comparisons or data fusion. To enhance semantic interoperability, the alignment of water-quality properties with definitions of chemical entities and units of measure in existing widely-used vocabularies is required. Modern ontologies and vocabularies are expressed, organized and deployed using Semantic Web technologies. We developed an ontology for observed properties (i.e. a model for expressing appropriate controlled vocabularies) which extends the NASA/TopQuadrant QUDT ontology for Unit and QuantityKind with two additional classes and two properties (see accompanying paper by Cox, Simons and Yu). We use our ontology to populate the Water Quality vocabulary with a set of individuals of each of the four key classes (and their subclasses), and add appropriate relationships between these individuals. This ontology is aligned with other relevant stand-alone Water Quality vocabularies and domain ontologies. Developing the Water Quality vocabulary involved two main steps. First, the Water Quality vocabulary was populated with individuals of the ObservedProperty class, which was determined from a census of existing datasets and services. Each ObservedProperty individual relates to other individuals of Unit and QuantityKind (taken from QUDT where possible), and to IdentifiedObject individuals. As a large fraction of observed water quality data are classified by the chemical substance involved, the

    Full Text Available Recently, manufacturing companies have to construct supply chains considering the contingencies of global clients. In order to meet global demand, companies are required to quickly grasp the information which is disseminated in the supply chain. This study focuses on business to business (B to B manufacturing model in a supply chain. Generally, manufacturing companies which supply the products to client companies engaged in B to B structures deliver the products according to the client companies’ order. Manufacturing companies subsequently deliver the product depending on the order specifications that determine the delivery time, the order quantity, the order quality and so on. Therefore, the orders requisitioned by client companies might cause some impacts on the operations in the companies engaged in B to B structures in the supply chain. We suggest a new approach to solving the operation problems using Quality Function Deployment (QFD. QFD is a powerful methodology and is effective in organizing manufacturing information and setting the quality of design. A case study is given to show the implementation of the proposed methodology.

    Full Text Available The Target Costing (Target Costing is a tool for strategic planning that considers a holistic view of their products and their compositions and identifies opportunities for cost reduction and product improvement. This mentality is incorporating the business community because, increasingly, the market is influenced by the value that customers attach to the product and its characteristics. Thus, one must determine the maximum cost that may be incurred to obtain the desired return from a price dictated by the market on which firms can not influence. It is different from the traditional concept, where price is a function of the cost it incurs to produce a particular good. The aim of this paper is to demonstrate through a literature review on the application of methods to reduce costs by integrating systems Target Costing and Kaizen supported by QFD (Quality Function Deployment improvements in existing product development and process optimization. We performed a literature search on the issues involved in the work and their interaction. It is noticed that, precisely in Japanese industries were some concepts and techniques used to date, considered very current and influencing business relationships with its suppliers. Among them may be mentioned: QFD and also the topic covered in this article, the system cost kaizen. This is due to the deep recession in which Japanese industries have passed since the 50s until the early 90s, which forced companies to reduce their fixed costs intensely and continuously improving its processes.

    Full Text Available The intrusion detection application in a homogeneous wireless sensor network is defined as a mechanism to detect unauthorized intrusions or anomalous moving attackers in a field of interest. The quality of deterministic sensor nodes deployment can be determined sufficiently by a rigorous analysis before the deployment. However, when random deployment is required, determining the deployment quality becomes challenging. An area may require that multiple nodes monitor each point from the sensing area; this constraint is known as k-coverage where k is the number of nodes. The deployment quality of sensor nodes depends directly on node density and sensing range; mainly a random sensor nodes deployment is required. The major question is centred around the problem of network coverage, how can we guarantee that each point of the sensing area is covered by the required number of sensor nodes and what a sufficient condition to guarantee the network coverage? To deal with this, probabilistic intrusion detection models are adopted, called single/multi-sensing detection, and the deployment quality issue is surveyed and analysed in terms of coverage. We evaluate the capability of our probabilistic model in homogeneous wireless sensor network, in terms of sensing range, node density, and intrusion distance.

    The Airlift Deployment Analysis System (ADANS) is an automated system that will provide Headquarters Military Airlift Command (HQMAC) and the Numbered Air Forces (NAFs) with planning, scheduling, and analytical tools for peacetime and contingency airlift operations. ADANS will consist of an algorithms subsystem for airlift planning, scheduling, and analysis; a relational database management system (RDBMS); a user friendly front-end subsystem; and communications software. ADANS will be completed by October 1992. It will be developed in three increments to provide an initial operating capability as quickly as possible. At the end of each increment, an operational airlift planning, scheduling, and analysis system will be installed. ADANS will provide automated tools for MAC mission support allocation, airlift scheduling, load allocation, and analysis of the airlift system. The ADANS scheduling algorithms and database will operate on the Deployment Flow Computer System (DFCS) at HQMAC, Scott Air Force Base. The DFCS will consist of Honeywell DPS 90/92 Tandem and Honeywell DPS 90/92 mainframe computers. User workstations will interface with the DFCS through two local area networks, one classified and one unclassified. The classified DFCS will be connected via a high-speed bus to HQMAC's System 1'' computer, a node on the Worldwide Military Command and Control System Intercomputer Network for communications with the Joint Deployment System and the Joint Operations Planning System. Systems currently under development that will interface with ADANS include the Joint Operation Planning and Execution System and the Global Decision Support System (GDSS). MAC Command and Control Information Processing System data will be available through GDSS. This command and control information will be accessed by ADANS so that analysts will have data on resources used within MAC's airlift system during plan and schedule development. 80 figs., 8 tabs.

    Full Text Available The flexibility is one of the priorities in manufacturing companies. However, the lack of guidelines for carrying out a critical analysis of the use of resources in manufacturing industry leads to a loss of process performance. This article describes a method to help companies identify the resources needed to provide manufacturing flexibility and meet the demands of their consumers while complying with company strategy. The literature related to flexibility is reviewed and a classification based on four levels is proposed: abilities, dimensions, elements and resources that provide flexibility. Based on this taxonomy and using the principles of QFD (Quality Function Deployment, a method is proposed that shows the correlation between these four levels, starting with customer demand and company strategy. The method was tested in an automobile manufacturing company, showing the applicability of the method. It highlighted the high degree of automation, which’s had serious problems related to restrictions on product mix. It can be inferred that this problem could be minimized by simplifying the tasks involved in the manufacture of car and by hiring more experienced, multi-skilled workers. The proposed method is different from those founded in the literature review because it deploys two levels more of flexibility, considering the QFD structure, and addresses strategic company issues.

    Healthcare organizations are faced with the responsibility of teaching their entire staff the founding principles, concepts, and practices of total quality management (TQM), to improve organizational effectiveness. Purchasing training products from outside consultants can be costly, but healthcare leaders can design and develop their own TQM training products, integrating each product with their organization's mission and values. This article describes how a Catholic healthcare system successfully developed and deployed a compendium of TQM educational products throughout the health-care system.

  9. Experiences and recommendations in deploying a real-time, water quality monitoring system

    Monitoring of water quality at a river basin level to meet the requirements of the Water Framework Directive (WFD) using conventional sampling and laboratory-based techniques poses a significant financial burden. Wireless sensing systems offer the potential to reduce these costs considerably, as well as provide more useful, continuous monitoring capabilities by giving an accurate idea of the changing environmental and water quality in real time. It is unlikely that the traditional spot/grab sampling will provide a reasonable estimate of the true maximum and/or mean concentration for a particular physicochemical variable in a water body with marked temporal variability. When persistent fluctuations occur, it is likely only to be detected through continuous measurements, which have the capability of detecting sporadic peaks of concentration. Thus, in situ sensors capable of continuous sampling of parameters required under the WFD would therefore provide more up-to-date information, cut monitoring costs and provide better coverage representing long-term trends in fluctuations of pollutant concentrations. DEPLOY is a technology demonstration project, which began planning and station selection and design in August 2008 aiming to show how state-of-the-art technology could be implemented for cost-effective, continuous and real-time monitoring of a river catchment. The DEPLOY project is seen as an important building block in the realization of a wide area autonomous network of sensors capable of monitoring the spatial and temporal distribution of important water quality and environmental target parameters. The demonstration sites chosen are based in the River Lee, which flows through Ireland's second largest city, Cork, and were designed to include monitoring stations in five zones considered typical of significant river systems--these monitor water quality parameters such as pH, temperature, depth, conductivity, turbidity and dissolved oxygen.

    2012-12-01

    Full Text Available In many organizations, management systems are viewed in terms of the internal dynamics between marketing, design, production, distribution, and accounting. A change is required from this to a larger system which also encompasses and integrates the business interests of customers and   suppliers. Management needs to develop an in-depth understanding of these relationships and how they may be used to cement the partnership concept. The quality function should be the organization’s focal point in this respect and should be equipped to gauge internal and external customers, expectations and degree of satisfaction. It should also identify quality deficiencies in all business functions and promote improvements. The role of the quality function is to make quality become an inseparable aspect of every employee’s performance and responsibility. The transition in many companies from quality departments with line functions will require careful planning, direction and monitoring. Quality professionals have developed numerous techniques and skills focused on product or service quality.

The adaptation consisted on the fact that matrices are treated in an unified manner among product and services due to the high perception of inter-relationship among these business components. The results evidenced that clients priorize traits related to the product, especially genetic value of the bulls. Service items were also highlighted, and they may be presented as an opportunity of differentiation among suppliers. Customer profile influenced priority order inasmuch as farmers with no technical services prioritized performance traits over genetic traits, opposing to those who were assisted and to technical consultants. Concerning to farm size, there were changes only in the tertiary level of the priority order of the demands. The adaptation of the methodology for joint analysis interfered in the results, especially in service prioritization.

    Special Operations Forces (SOF) Soldiers deploy frequently and require high levels of physical and cognitive performance. Nutritional status is linked to cognitive and physical performance. Studies evaluating dietary intake and nutritional status in deployed environments are lacking. Therefore, this study assessed the effects of combat deployment on diet quality and serum concentrations of nutritional status markers, including iron, vitamin D, parathyroid hormone (PTH), glucose, and lipids, among elite United States (U.S.) Army SOF Soldiers. Changes from baseline to post-deployment were determined with a repeated measure within-subjects design for Healthy Eating Index-2010 (HEI-2010) scores, intake of foods, food groups, key nutrients, and serum nutritional status markers. Dietary intake was assessed with a Block Food Frequency Questionnaire. The association between post-deployment serum 25-hydroxy vitamin D (25-OH vitamin D) and PTH was determined. Analyses of serum markers were completed on 50 participants and analyses of dietary intake were completed on 33 participants. In response to deployment, HEI-2010 scores decreased for total HEI-2010 (70.3 ± 9.1 vs. 62.9 ± 11.1), total fruit (4.4 ± 1.1 vs. 3.7 ± 1.5), whole fruit (4.6 ± 1.0 vs. 4.2 ± 1.4), dairy (6.2 ± 2.7 vs. 4.8 ± 2.4), and empty calories (14.3 ± 3.2 vs. 11.1 ± 4.5) (P ≤ 0.05).

    Functional microorganisms and health benefits represent a binomial with great potential for fermented functional foods. The health benefits of fermented functional foods are expressed either directly through the interactions of ingested live microorganisms with the host (probiotic effect) or indirectly as the result of the ingestion of microbial metabolites synthesized during fermentation (biogenic effect). Since the importance of high viability for probiotic effect, two major options are currently pursued for improving it--to enhance bacterial stress response and to use alternative products for incorporating probiotics (e.g., ice cream, cheeses, cereals, fruit juices, vegetables, and soy beans). Further, it seems that quorum sensing signal molecules released by probiotics may interact with human epithelial cells from intestine thus modulating several physiological functions. Under optimal processing conditions, functional microorganisms contribute to food functionality through their enzyme portfolio and the release of metabolites. Overproduction of free amino acids and vitamins are two classical examples. Besides, bioactive compounds (e.g., peptides, γ-amino butyric acid, and conjugated linoleic acid) may be released during food processing above the physiological threshold and they may exert various in vivo health benefits. Functional microorganisms are even more used in novel strategies for decreasing phenomenon of food intolerance (e.g., gluten intolerance) and allergy. By a critical approach, this review will aim at showing the potential of functional microorganisms for the quality of functional foods.

    The Nuclear Safety is the main goal in any nuclear facility. In this sense the Norm CNEN-NN-1.16 classifies the quality assurance issue as a management system to be deployed and implemented by the organization to achieving security goals. Quality Assurance is a set of systematic and planned actions necessary to provide adequate confidence ensuring that a structure, system, component or installation will work satisfactorily in s. Hence, the Quality Assurance System (QAS) is a complete and comprehensive methodology, going far beyond a management plan quality from the perspective of project management. The fundamental of QAS requirements is all activities that influence the quality, involving organizational, human resources, procurement, nuclear safety, projects, procedures and communication. Coordination of all these elements requires a great effort by the team responsible because it usually involves different areas and different levels of hierarchy within the organization. The objectives and desired benefits should be well set for everyone to understand what it means to be achieved and how to achieve. The support of senior management is critical at this stage, providing guidelines and resources necessary to get the job elapse clearly and efficiently, on time, cost and certain scope. The methodology of project management processes can be applied to facilitate and expedite the implementation of this system. Many of the principles of the QAS are correlated with knowledge areas of project management. The proposed model for implementation of a QAS in the nuclear fuel cycle facilities considered the best project management practices according to the Project Management Book of Knowledge (PMBOK - 5th edition) of the Project Management Institute (PMI). This knowledge is considered very good practices around the world. Since the model was defined, the deployment process becomes more practical and efficient, providing reduction in deployment time, better management of human

    monomer distribution, it was important to gauge this effect in reservoir analogues. A reservoir rock will act as a large chromatography column, separating out the scale inhibitor according to molecular weight and phosphorus content. That is the larger molecular weights will adhere more strongly than lower molecular weight fractions, whereas polymer chains containing larger phosphorus functionality will adhere to the rock significantly stronger than those without. Thus it is important to understand if there were components containing phosphorus but did not contribute to the inhibition of scale. In order to study these effects the phosphorus functionalized polymers were tested on very clean sandstone core plugs in a core flood rig. Their adsorption/retention characteristics were studied. The scale inhibitor effluent was analyzed by numerous methods and confirmed by inhibition efficiency measurements. Following successful development, one of the phosphorus functionalized polymeric inhibitors was subject to sequential field-trial in a harsh BaSO{sub 4} scaling, highly naturally fractured North Sea carbonate reservoir. As this was the first deployment of this novel technology the scale inhibitor returns and water chemistry were monitored using a number of methods to assess the efficiency of the inhibitor at mitigating the BaSO{sub 4} risk. A number of previous technologies utilizing phosphorus tagging have resulted in false readings due to anomalous phosphorus signals. The results presented in this paper show a step change with the scale inhibitor analysis by both elemental phosphorus (ICP-OES) and polymer methods (cartridge/Hyamine) showing excellent correlation. Indirect analysis of the scale inhibitor performance by elemental Ba{sup 2+} measurement confirmed the results, as there was no drop in Ba{sup 2+} concentration indicating no significant scaling before the re-squeeze operation was conducted. The phosphorus functionalized inhibitor provided superior performance

    Full Text Available Quality function may be summarised as quality generation, quality control, and qualityassurance. The quality generation and quality control, because of their fuactional nature, arecomparatively easy to organise, however, the challenge is to organise quality assurance in theorganisation. It is the challenge because quality assurance should seamlessly merge with theR&D process. In future, the organisations, whether real or virtual, are going to bepredominantly, research and development (R&D oriented rather than pure manufacturing orservice providers. However, the nature and intensity of the R&D may differ. It could be fromsimple improvement to innovation, to exploitation of inventions.Organising quality function in R&D means organising its various dimensions against thestipulated criteria such as the realisation of the quality system; realisation of quality duringproduct development, including system engineering; staffing of quality generation, quality control,and quality assurance; balancing of the quality function; harnessing of project quality, functionalquality, staff quality and line quality; application of the RHR principle; exploitation of the toolsof organising, democratic organisation; and so on. The basic purpose of organising the qualityfunction is to inculcate the sense of pride in quality among the scientists so that they feelpassionate about it. It is the passion and love for quality that generates, sustains, and maintainsquality.

  11. FUNCTIONS AND REQUIREMENTS FOR RUSSIAN PULSATING MONITOR DEPLOYMENT IN THE GUNITE AND ASSOCIATED TANKS AT OAK RIDGE NATIONAL LABORATORY

    1999-01-01

    This document provides functions and requirements to support deployment of pulsating mixer pump technology in the Oak Ridge National Laboratory (ORNL) Gunite and Associated Tanks to mobilize and mix the settled sludge and solids in these tanks. In FY 1998 pulsating mixer pump technology, a jet mixer powered by a reciprocating air supply, was selected for FY 1999 deployment in one of the GAAT tanks to mobilize settled solids. Pulsating mixer pump technology was identified in FY 1996 during technical exchanges between the US Department of Energy (DOE) Tanks Focus Area Retrieval and Closure program, the DOE Environmental Management International Programs, and delegates from Russia as a promising technology that could be implemented in the US. The pulsating mixer pump technology, provided by the Russian Integrated Mining Chemical Company, was tested at Pacific Northwest National Laboratory (PNNL) to observe its ability to mobilize settled solids. Based on the results of this demonstration, ORNL and DOE staff determined that a modified pulsating mixer pump would meet project needs for bulk mobilization of Gunite tank sludge prior to deployment of other retrieval systems. The deployment of this device is expected to significantly reduce the costs of operation and maintenance of more expensive retrieval systems. The functions and requirements presented here were developed by evaluating the results and recommendations that resulted from the pulsating mixer pump demonstration at PNNL, and by coupling this with the remediation needs identified by staff at ORNL involved with the remediation of the Gunite and Associated Tanks.

    The relationship between military combat and postdeployment family functioning difficulties has been frequently investigated in the literature, as has the relationship between types of coping and posttraumatic stress disorder (PTSD). Few studies, however, have examined these variables together, and no studies of which we are aware have examined the effect of coping on family functioning after combat exposure. This study examined coping style measured immediately after return from deployment, and PTSD symptoms and family functioning 18-24 months after return from deployment in a sample of Operation Desert Shield/Storm veterans (N = 2,949). Structural equation models suggested that the relationships between distinct coping styles on family functioning were differentially mediated by postdeployment PTSD symptoms. Results are consistent with full mediation for avoidant coping (βdirect = -.09, p = .07; βindirect = -.17, p family functioning outcomes, and highlight the potential utility of pre- and postdeployment coping skills training.

    Over the past 20 years, functional magnetic resonance imaging (fMRI) has ben- efited greatly from improvements in MRI hardware and software. At the same time, fMRI researchers have pushed the technical limits of MRI systems and greatly in- fluenced the development of state-of-the-art systems....... Minimizing image noise and maximizing system stability is critical in fMRI because the blood oxygenation level- dependent (BOLD) signal changes that are used for most fMRI studies represent only a small fraction of the total MR signal. In addition, multiple imaging volumes must be acquired over time to track...... cognitive processes. As a result, MRI scanners must have excellent time-series stability to accurately measure BOLD signal changes over the course of a long time series (typically on the order of 10 min per scan). fMRI studies are particularly demanding on the scanner hardware because they utilize fast...

    This report for the International Energy Agency (IEA) made by Task 9 of the Photovoltaic Power Systems (PVPS) programme takes a look at the role of quality management, hardware certification and accredited training in PV programmes in developing countries. The objective of this document is to provide assistance to those project developers that are interested in implementing or improving support programmes for the deployment of PV systems for rural electrification. It is to enable them to address and implement quality assurance measures, with an emphasis on management, technical and training issues and other factors that should be considered for the sustainable implementation of rural electrification programmes. It is considered important that quality also addresses the socio-economic and the socio-technical aspects of a programme concept. The authors summarise that, for a PV programme, there are three important areas of quality control to be implemented: quality management, technical standards and quality of training.

    Deployable structure composed of smart materials based actuators can reconcile its inherently conflicting requirements of low mass, good shape adaptability, and high load-bearing capability. This work describes the fabrication of deployable structures using smart soft composite actuators combining a soft matrix with variable stiffness properties and hinge-like movement through a rigid skeleton. The hinge actuator has the advantage of being simple to fabricate, inexpensive, lightweight and simple to actuate. This basic actuator can then be used to form modules capable of different types of deformations, which can then be assembled into deployable structures. The design of deployable structures is based on three principles: design of basic hinge actuators, assembly of modules and assembly of modules into large-scale deployable structures. Various deployable structures such as a segmented triangular mast, a planar structure comprised of single-loop hexagonal modules and a ring structure comprised of single-loop quadrilateral modules were designed and fabricated to verify this approach. Finally, a prototype for a deployable mirror was developed by attaching a foldable reflective membrane to the designed ring structure and its functionality was tested by using it to reflect sunlight onto to a small-scale solar panel.

    The Event Filter selection stage is a fundamental component of the ATLAS Trigger and Data Acquisition architecture. Its primary function is the reduction of data flow and rate to values acceptable by the mass storage operations and by the subsequent off-line data reconstruction and analysis steps. The computing instrument of the EF is generally organized as a set of independent sub-farms, each connected to one output of the Event Builder switch fabric. Each sub-farm comprises a number of processors analyzing several complete events in parallel. This paper describes the design of the ATLAS EF system, its deployment in the 2004 ATLAS combined test beam together with some examples of integrating selection and monitoring algorithms. Since the processing algorithms are not specially designed for EF but are inherited as much as possible from the off-line ones, special emphasis is reserved to system reliability and data security, in particular for the case of failures in the processing algorithms.

    Full Text Available Customer involvement in infrastructure maintenance activities is a complex process due to various decision-making parameters surrounding maintenance. Compared to manufacturing and other disciplines where QFD is widely used, expectations of the infrastructure user as a customer are truly dynamic given the changing economic conditions, technologies, environmental regulations, etc. While such dynamic or changing customer expectations can be addressed by repeated surveys and constant communication, having indicators to predict customer response would be a valuable tool and aid the QFD decision-making process. In this study, a framework that utilizes hidden Markov model (HMM is proposed for evaluating customer expectation by using probabilities of focus areas that are of interest to the infrastructure user as hidden parameters. The focus areas are based on sustainability parameters and include economic, social, technological, maintenance efficiency, safety and environmental conditions. Probabilities that represent the probability of transition from current state (of the focus area to next possible state were generated based on expert opinion of the authors. Using the 2005 customer survey by California Transportation, a case study is presented in order to demonstrate the application which concludes that the proposed methodology can be successfully implemented for infrastructure maintenance.

A reliable electrical power is required for a NPP to facilitate cooling after a shutdown. Failure of electrical power supply during shutdown increases core damage probability. Research shows that a total of 39% of LOOP related events in US are electrical grid centered. In Korea, 38% and 29% of all events that led to NPP shutdown at Hanul units 3-6 and at Hanbit units 3-6 respectively were electrical related. Electric grids for both operating and new NPPs must therefore be examined and upgraded for reliability improvement in order to enhance NPP safety.

    2014-07-01

    Full Text Available In cloud computing environments, context information is continuously created by context providers and consumed by the applications on mobile devices. An important characteristic of cloud - based context aware services is meeting the service level agreements (SLAs to deliver a certain quality of service (Qos , s uch as guarantees on response time or price. The response time to a request of context - aware software is affected by loading extensive context data from multiple resources on the chosen server. Therefore, the speed of such software would be decreased durin g execution time. Hence, proper scheduling of such services is indispensable because the customers are faced with time constraints. In this research, a new schedul ing algorithm for context aware services is proposed which is based on classifying similar co ntext consumers and dynamically scoring the requests to improve the performance of the server hosting highly - requested context - aware software while reducing costs of cloud provider. The approach is evaluated via simulation and comparison with gi - FIFO sched uling algorithm. Experimental results demonstrate the efficiency of the proposed app roach

  19. Toward Governance of Cross-Cloud Application Deployment

    CERN Document Server

    de Leusse, Pierre

    2012-01-01

    In this article, the authors introduce the main ideas around the governance of cross-Cloud application deployment and their related concepts. It is argued that, due to the increasing complexity and nature of the Cloud market, an intermediary specialized in brokering the deployment of different components of a same application onto different Cloud products could both facilitate said deployment and in some cases improve its quality in terms of cost, security & reliability and QoS. In order to fulfill these objectives, the authors propose a high level architecture that relies on their previous work on governance of policy & rule driven distributed systems. This architecture aims at supplying five main functions of 1) translation of Service Level Agreements (SLAs) and pricing into a common shared DSL, 2) correlation of analytical data (e.g. monitoring, metering), 3) combination of Cloud products, 4) information from third parties regarding different aspects of Quality of Service (QoS) and 5) cross-Cloud a...

    Wang, J; Templeton, D C

    2012-03-21

    This report summarizes the seismic deployment of Lawrence Livermore National Laboratory (LLNL) Geotech GS-13 short-period seismometers at the Newberry Enhanced Geothermal System (EGS) Demonstration site located in Central Oregon. This Department of Energy (DOE) demonstration project is managed by AltaRock Energy Inc. AltaRock Energy had previously deployed Geospace GS-11D geophones at the Newberry EGS Demonstration site, however the quality of the seismic data was somewhat low. The purpose of the LLNL deployment was to install more sensitive sensors which would record higher quality seismic data for use in future seismic studies, such as ambient noise correlation, matched field processing earthquake detection studies, and general EGS microearthquake studies. For the LLNL deployment, seven three-component seismic stations were installed around the proposed AltaRock Energy stimulation well. The LLNL seismic sensors were connected to AltaRock Energy Gueralp CMG-DM24 digitizers, which are powered by AltaRock Energy solar panels and batteries. The deployment took four days in two phases. In phase I, the sites were identified, a cavity approximately 3 feet deep was dug and a flat concrete pad oriented to true North was made for each site. In phase II, we installed three single component GS-13 seismometers at each site, quality controlled the data to ensure that each station was recording data properly, and filled in each cavity with native soil.

    2014-06-01

    Full Text Available In dam concrete construction process, it not only has quality loss arising from quality fluctuation, but also gains quality compensation effect due to the mutual cooperation and adaptation coupling between working procedures (WPs. The calculation and transmission complexity of the quality loss and quality compensation affect the quality management of dam concrete construction. As the quality compensation effect existing in the production practice cannot be described by Taguchi quality loss function, the concept of quality gain-loss function was presented in this paper, which was based on endowing the constant term in the expansion of Taylor series with physical meaning—quality compensation. Based on quality gain-loss function theory, a new quality gain-loss transmission model of dam concrete construction based on GERT network was constructed and its effective algorithm was designed. WP quality gain-loss and its impact on the final product were reasonably measured, and the critical quality routes and critical quality WPs were detected and diagnosed in dam concrete construction network. Summer temperature-controlled concrete construction in the third phase of Three Gorges Project (TGP was taken as an example to carry out the study, and the calculation results showed the validity and practicability of the presented model and algorithm.

  2. Modeling and Deployment of Model-Based Decentralized Embedded Diagnosis inside Vehicles: Application to Smart Distance Keeping Function

    Directory of Open Access Journals (Sweden)

    Othman Nasri

    2012-01-01

    Full Text Available The deployment of a fault diagnosis strategy in the Smart Distance Keeping (SDK system with a decentralized architecture is presented. The SDK system is an advanced Adaptive Cruise Control (ACC system implemented in a Renault-Volvo Trucks vehicle to increase safety by overcoming some ACC limitations. One of the main differences between this new system and the classical ACC is the choice of the safe distance. This latter is the distance between the vehicle equipped with the ACC or the SDK system and the obstacle-in-front (which may be another vehicle. It is supposed fixed in the case of the ACC, while variable in the case of the SDK. The variation of this distance depends essentially on the relative velocity between the vehicle and the obstacle-in-front. The main goal of this work is to analyze measurements, issued from the SDK elements, in order to detect, to localize, and to identify some faults that may occur. Our main contribution is the proposition of a decentralized approach permitting to carry out an on-line diagnosis without computing the global model and to achieve most of the work locally avoiding huge extra diagnostic information traffic between components. After a detailed description of the SDK system, this paper explains the model-based decentralized solution and its application to the embedded diagnosis of the SDK system inside Renault-Volvo Truck with five control units connected via a CAN-bus using “Hardware in the Loop” (HIL technique. We also discuss the constraints that must be fulfilled.

    Many platforms have emerged as response to the call for technology supporting active and healthy aging. Key requirements for any such e-health systems and any subsequent business exploitation are tailor-made design and proper evaluation. This paper presents the design, implementation, wide deployment, and evaluation of the low cost, physical exercise, and gaming (exergaming) FitForAll (FFA) platform system usability, user adherence to exercise, and efficacy are explored. The design of FFA is tailored to elderly populations, distilling literature guidelines and recommendations. The FFA architecture introduces standard physical exercise protocols in exergaming software engineering, as well as, standard physical assessment tests for augmented adaptability through adjustable exercise intensity. This opens up the way to next generation exergaming software, which may be more automatically/smartly adaptive. 116 elderly users piloted FFA five times/week, during an eight-week controlled intervention. Usability evaluation was formally conducted (SUS, SUMI questionnaires). Control group consisted of a size-matched elderly group following cognitive training. Efficacy was assessed objectively through the senior fitness (Fullerton) test, and subjectively, through WHOQoL-BREF comparisons of pre-postintervention between groups. Adherence to schedule was measured by attendance logs. The global SUMI score was 68.33±5.85%, while SUS was 77.7. Good usability perception is reflected in relatively high adherence of 82% for a daily two months pilot schedule. Compared to control group, elderly using FFA improved significantly strength, flexibility, endurance, and balance while presenting a significant trend in quality of life improvements. This is the first elderly focused exergaming platform intensively evaluated with more than 100 participants. The use of formal tools makes the findings comparable to other studies and forms an elderly exergaming corpus.

  10. DEVELOPMENT OF REALISTIC QUALITY LOSS FUNCTIONS FOR INDUSTRIAL APPLICATIONS

    Institute of Scientific and Technical Information of China (English)

    Abdul-Baasit SHAIBU; Byung Rae CHO

    2006-01-01

    A number of quality loss functions, most recently the Taguchi loss function, have been developed to quantify the loss due to the deviation of product performance from the desired target value. All these loss functions assume the same loss at the specified specification limits. In many real life industrial applications, however, the losses at the two different specifications limits are often not the same.Further, current loss functions assume a product should be reworked or scrapped if product performance falls outside the specification limits. It is a common practice in many industries to replace a defective item rather than spending resources to repair it, especially if considerable amount of time is required. To rectify these two potential problems, this paper proposes more realistic quality loss functions for proper applications to real-world industrial problems. This paper also carries out a comparison studies of all the loss functions it considers.

    Thomson, M. W.

    1994-01-01

    A new deployable and retractable telescoping boom capable of high deployed stiffness and strength is described. Deployment and retraction functions are controlled by simple, reliable, and fail-safe latches between the tubular segments. The latch and a BI-STEM (Storable Tubular Extendible Member) actuator work together to eliminate the need for the segments to overlap when deployed. This yields an unusually lightweight boom and compact launch configuration. An aluminum space-flight prototype with three joints displays zero structural deadband, low hysteresis, and high damping. The development approach and difficulties are discussed. Test results provide a joint model for sizing flight booms of any diameter and length.

    2016-07-01

    This paper addresses a comprehensive modeling and functionality evaluation of a module-based quality system in production logistics at the highest domain abstract level of business processes. All domain quality business processes and quality data transactions are modeled using BPMN and UML tools and standards at the business process and data modeling. A modular web-based prototype is developed to evaluate the models addressing the quality information system functionality requirements and modularity in production logistics through data scenarios and data queries. Using the object-oriented technique in design at the highest domain level, the proposed models are subject further development in the lower levels for the implementing case. The models are specifically able to manipulate all quality operations including remedy and control in a lot-based make-to-order production logistics system as an individual module. Due to the specification of system as domain design structure, all proposed BPMs, data models, and the actual database prototype are seen referential if not a solution as a practical “to-be” quality business process re-engineering template. This paper sets out to provide an explanatory approach using different practical technique at modeling steps as well as the prototype implementation. (Author)

    1993-01-01

    This handbook sets forth requirements for NASA direction and management of government quality assurance functions performed for NASA contracts and is applicable to all NASA installations. These requirements will standardize management to provide the minimum oversight and effective use of resources. This handbook implements Federal Acquisition Regulation (FAR) Part 46, NASA FAR Supplement 18-46, Quality Assurance, and NMI 7410.1. Achievement of established quality and reliability goals at all levels is essential to the success of NASA programs. Active participation by NASA and other agency quality assurance personnel in all phases of contract operations, including precontract activity, will assist in the economic and timely achievement of program results. This involves broad participation in design, development, procurement, inspection, testing, and preventive and corrective actions. Consequently, government, as well as industry, must place strong emphasis on the accomplishment of all functions having a significant bearing on quality and reliability from program initiation through end-use of supplies and services produced. For purposes of implementing NASA and other agency agreements, and to provide for uniformity and consistency, the terminology and definitions prescribed herein and in a future handbook shall be utilized for all NASA quality assurance delegations and subsequent redelegations.

  18. Controlling for quality in the hospital cost function.

    Carey, Kathleen; Stefos, Theodore

    2011-06-01

    This paper explores the relationship between the cost and quality of hospital care from the perspective of applied microeconomics. It addresses both theoretical and practical complexities entailed in incorporating hospital quality into the estimation of hospital cost functions. That literature is extended with an empirical analysis that examines the use of 15 Patient Safety Indicators (PSIs) as measures of hospital quality. A total operating cost function is estimated on 2,848 observations from five states drawn from the period 2001 to 2007. In general, findings indicate that the PSIs are successful in capturing variation in hospital cost due to adverse patient safety events. Measures that rely on the aggregate number of adverse events summed over PSIs are found to be superior to risk-adjusted rates for individual PSIs. The marginal cost of an adverse event is estimated to be $22,413. The results contribute to a growing business case for inpatient safety in hospital services.

    Zohreh Bostaki

    2014-04-01

    Full Text Available In the contexture of a customer-driven goods or service design process, a well-timed update of customer’s requirements may not only serve as a necessity indicator to observe how things change over time, but also it incorporates the firms a better ground to interoperate different strategies to meet the future needs of its customer. This paper proposes a systematic methodology to deal with the customer needs’ dynamics, in terms of their relative weights, in the QFD. Compared with previous research, the contribution of this paper is fourfold. First, it applies some linguistic variables to get preferences of customers and experts to determine the relative importance of customer requirements (CRs and the relationships between customer requirements and engineering characteristics (ECs. Second, it proposes the implementation of a forecasting technique. Third, it describes more comprehensively on how future uncertainty in the weights of customer’s needs could be estimated and transmitted into the design attributes. Fourth, it proposes the implementation of a quantitative approach, which takes into account the decision maker’s attitude towards risk to optimize the QFD decision making analysis. Finally, a real-world application of QFD is provided to demonstrate the practical applicability of the proposed methodology.

    The ability to produce and maintain salad crops during long term missions would be a great benefit to NASA; the renewable food supply would save cargo space, weight and money. The ambient conditions of previous ground controlled crop plant experiments do not reflect the microgravity and high CO2 concentrations present during orbit. It has been established that microgravity does not considerably alter plant growth. (Monje, Stutte, Chapman, 2005). To support plants in a space-craft environment efficient and effective lighting and containment units are necessary. Three lighting systems were previously evaluated for radish growth in ambient air; fluorescent lamps in an Orbitec Biomass Production System Educational (BPSE), a combination of red, blue, and green LED's in a Deployable Vegetable Production System (Veggie), and a combination of red and blue LED's in a Veggie. When mass measurements compared the entire possible growing area vs. power consumed by the respective units, the Veggies clearly exceeded the BPSE indicating that the LED units were a more resource efficient means of growing radishes under ambient conditions in comparison with fluorescent lighting. To evaluate the most productive light treatment system for a long term space mission a more closely simulated ISS environment is necessary. To induce a CO2 dense atmosphere inside the Veggie's and BPSE a gas exchange system has been developed to maintain a range of 1000-1200 ppm CO2 during a 21-day light treatment experiment. This report details the design and function of the gas exchange system. The rehabilitation, trouble shooting, maintenance and testing of the gas exchange system have been my major assignments. I have also contributed to the planting, daily measurements and harvesting of the radish crops 21-day light treatment verification test.

    Full Text Available OBJECTIVES: To evaluate the impact of the chronic kidney disease (CKD on quality of life, from the children's and their parents' perspective, respiratory muscle strength, lung function, and functional capacity in children and adolescents. METHOD: Cross-sectional study of children with CKD aged 8 to 17 years. Those incapable of taking the tests were excluded. After an interview, quality of life by Pediatric Quality of Life Inventory (PedsQLTM, muscular strength, pulmonary function tests, and the 6-minute walking test (6MWT were applied. Student's t-test, ANOVA (difference in means, and Pearson's coefficient of correlation were used. The level of significance was set at 5%. RESULTS: Of the 40 patients, the mean distance walked at the 6MWT was 396 meters, and the mean final score at the quality of life test as perceived by the children and parents was 50.9 and 51, respectively. From the children's perspective, the transplanted patients had a higher quality of life score when compared to those undergoing hemodialysis (p < 0.001; those who practiced physical activity had better quality of life when compared to the sedentary children (p < 0.001. From the children's and the parents' perspectives, the male gender had a higher quality of life score (p < 0.05. There was a positive correlation between the distance walked at the 6MWT and age, height, final PedsQLTM, forced vital capacity (FVC, and forced expiratory volume in the first second (FEV1, as well as a negative correlation between FEV1/FVC and the distance walked. CONCLUSION: A significant reduction in the quality of life and the functional capacity was observed in children with CKD, influenced by the type of treatment, gender, and sedentary life style.

    Too little is known about human functioning amidst chronic adversity. We addressed that need by studying adult Palestinians in the occupied Palestinian territories (oPt), a population that has experienced longstanding economic and political hardships. Fourteen group interviews were conducted in February, 2010 in Arabic by local fieldworkers with 68 participants representing the main stratifications of Palestinian society: gender, region, refugee status, and political affiliation. Interview tasks included each participant: describing someone doing well and not well, free listing domains of functioning, and prioritizing domains to the three most important. Thematic analyses highlighted the dominating role of the political domain of functioning (e.g., political structures, constraints, effects, identity, and activism) and the degree to which political conditions impacted all other realms of functioning (economic, education, family, psychological, etc.). The discussion links the findings to relevant theory and empirical work that has called attention to the need to include the political in frameworks of quality of life. It also emphasized that values, such as justice, rights, dignity and self-determination, that underlie political structures and policies, are key elements of human functioning. This is the case not only in the oPt, but in any society where power imbalances marginalize segments of the population.

    1986-01-01

    A collapsible-expandable truss structure, including first and second spaced surface truss layers having an attached core layer is described. The surface truss layers are composed of a plurality of linear struts arranged in multiple triangular configurations. Each linear strut is hinged at the center and hinge connected at each end to a nodular joint. A passive spring serves as the expansion force to move the folded struts from a stowed collapsed position to a deployed operative final truss configuration. A damper controls the rate of spring expansion for the synchronized deployment of the truss as the folded configuration is released for deployment by the restrain belts. The truss is synchronously extended under the control of motor driven spools.

    The deployment problem, researched primarily in the military sector, is emerging in some other industries, mining included. The principal decision is how to deploy some activities in space and time to achieve desired outcome while complying with certain requirements or limits. Requirements and limits are on the side constraints, while minimizing costs or maximizing some benefits are on the side of objectives. A model with application to mining of polymetallic deposit is presented. To obtain quick and immediate decision solutions for a mining engineer with experimental possibilities is the main intention of a computer-based tool. The task is to determine strategic deployment of mining activities on a deposit, meeting planned output from the mine and at the same time complying with limited reserves and haulage capacities. Priorities and benefits can be formulated by the planner.

    This study explored the impact of hair pulling on psychosocial functioning for patients diagnosed with trichotillomania (TTM; n = 28). TTM patients were compared to age and gender-matched groups of psychiatric patients without TTM (n = 28) and nonpsychiatric control volunteers (NC, n = 28) on measures of psychological distress, functioning/quality of life, and self-esteem. Results indicated that TTM patients reported more severe psychosocial impairments than did NC volunteers; however, these differences were mediated by differences in level of depression. Regression analyses indicated significant relationships between some measures of psychosocial functioning and severity of hair pulling, independent of level of depression. Finally, an interview of the impact of hair pulling on 6 domains of daily functioning (negative affect/negative self-evaluations, grooming, recreational activities, social interaction, work/housework productivity, and physical health) indicated common and wide-ranging impairments for both lifetime and current (i.e., past week) ratings. These results highlight the importance of promoting and improving resources for the clinical care of TTM patients, and provide some directions for clinicians to enhance assessment of interference caused by TTM.

    Motor function, cognition, functional independence and quality of life have been described in myelomeningocele patients, but no study has investigated their relationships. We aimed to investigate the relationships between motor function, cognition, functional independence, quality of life, age, and lesion level in myelomeningocele patients, and investigate the influence of hydrocephalus on these variables. We assessed 47 patients with the Gross Motor Function Measure (motor function), Raven's Colored Progressive Matrices (cognition), Pediatric Evaluation of Disability Inventory (functional independence) and the Autoquestionnaire Qualité de vie Enfant Imagé (quality of life). Spearman's correlation tests determined relationships between the variables. The Friedman ANOVAs determined the influence of hydrocephalus. Motor function was strongly related to mobility and lesion level, and moderately related to cognition, self-care and social function. Cognition and quality of life were moderately related to functional independence. Age correlated moderately with functional independence and quality of life. Hydrocephalus resulted in poorer motor/cognitive outcomes and lower functional independence.

    In this paper, a new type of lightweight passive deployment mechanism based on the tape spring and the shape memory alloy is presented for the secondary mirror of a deployable space telescope. In this passive deployment mechanism for the secondary mirror, the high elastic potential energy of the folded tape springs is used as driving force when the support structure is extended, and the high stiffness characteristics of the circular arc cross section of the tape spring can be used to achieve structure self-locking after deployment. Then a deployable space telescope combined with lightweight passive deployable mechanism for the secondary mirror is designed for applying to nanosatellite imaging. Furthermore, a lock-release device is designed to achieve the function of locking the folded structure and releasing on orbit by taking advantage of the phase transformation characteristics of shape memory alloy with temperature changing. Finally, the correction method for the deployment error of secondary mirror is discussed. The temperature of the tape springs is controlled respectively to make a required length change. This can achieve the purpose of adjusting the position of the secondary mirror and improve the deployment accuracy.

    This Project Implementation Plan (PIP) shall be the controlling document for the Accelerated Site Technology Deployment (ASTD) supported project to procure and qualify a remote/robotic work platform for large hot cell deactivation in the 324 Building B-Cell. This plan will be integrated into the 324/327 Buildings Stabilization/Deactivation Project, Project Management Plan, (HNF-IP-1289, Rev. 1) and shall comply with the base requirements established in that document. This PIP establishes the baseline and defines the scope, schedule, budget, organizational responsibilities, reporting requirements, deliverables, and end points for the implementation of new technology into B-Cell. This shall include procurement, safety, quality assurance, training, documentation, record management, and facility modifications applicable to this project. Specifically this plan controls and executes the procurement and acceptance, qualification, and turnover of a remote/robotic work platform for 324 Building B-Cell. This includes the development of functional parameters, performance requirements, evaluation criteria, procurement specifications, acceptance and qualification test procedures, training requirements, and turnover responsibilities. The 324/237 Buildings Stabilization/Deactivation Project is currently in its second year of a nine-year project to complete deactivation and closure of the facility for long-term surveillance and maintenance. A major obstacles for the project is the inability to effectively perform deactivation tasks within high radioactively contaminated hot cells. The current strategies utilize inefficient and resource intensive technologies that significantly impact the cost and schedule for stabilization and deactivation. The ASTD Remote Deployment Project shall identify, procure, and turnover, to the B-Cell project, a remote/robot work platform to improve B-Cell cleanup productivity and enhance worker safety and health.

  7. Dedicated Deployable Aerobraking Structure

    Giersch, Louis R.; Knarr, Kevin

    2010-01-01

    A dedicated deployable aerobraking structure concept was developed that significantly increases the effective area of a spacecraft during aerobraking by up to a factor of 5 or more (depending on spacecraft size) without substantially increasing total spacecraft mass. Increasing the effective aerobraking area of a spacecraft (without significantly increasing spacecraft mass) results in a corresponding reduction in the time required for aerobraking. For example, if the effective area of a spacecraft is doubled, the time required for aerobraking is roughly reduced to half the previous value. The dedicated deployable aerobraking structure thus enables significantly shorter aerobraking phases, which results in reduced mission cost, risk, and allows science operations to begin earlier in the mission.

    2010-01-01

    Currently existing approaches for deployment of large, ultra-lightweight gossamer structures in space rely typically upon electromechanical mechanisms and mechanically expandable or inflatable booms for deployment and to maintain them in a fully deployed, operational configuration. These support structures, with the associated deployment mechanisms, launch restraints, inflation systems, and controls, can comprise more than 90 percent of the total mass budget. In addition, they significantly increase the stowage volume, cost, and complexity. A CHEM (cold hibernated elastic memory) membrane structure without any deployable mechanism and support booms/structure is deployed by using shape memory and elastic recovery. The use of CHEM micro-foams reinforced with carbon nanotubes is considered for thin-membrane structure applications. In this advanced structural concept, the CHEM membrane structure is warmed up to allow packaging and stowing prior to launch, and then cooled to induce hibernation of the internal restoring forces. In space, the membrane remembers its original shape and size when warmed up. After the internal restoring forces deploy the structure, it is then cooled to achieve rigidization. For this type of structure, the solar radiation could be utilized as the heat energy used for deployment and space ambient temperature for rigidization. The overall simplicity of the CHEM self-deployable membrane is one of its greatest assets. In present approaches to space-deployable structures, the stow age and deployment are difficult and challenging, and introduce a significant risk, heavy mass, and high cost. Simple procedures provided by CHEM membrane greatly simplify the overall end-to-end process for designing, fabricating, deploying, and rigidizing large structures. The CHEM membrane avoids the complexities associated with other methods for deploying and rigidizing structures by eliminating deployable booms, deployment mechanisms, and inflation and control systems

    Full Text Available Wireless sensor networks face significant design challenges due to limited computing and storage capacities and, most importantly, dependence on limited battery power. Energy is a critical resource and is often an important issue to the deployment of sensor applications that claim to be omnipresent in the world of future. Thus optimizing the deployment of sensors becomes a major constraint in the design and implementation of a WSN in order to ensure better network operations. In wireless networking, clustering techniques add scalability, reduce the computation complexity of routing protocols, allow data aggregation and then enhance the network performance. The well-known MaxMin clustering algorithm was previously generalized, corrected and validated. Then, in a previous work we have improved MaxMin by proposing a Single- node Cluster Reduction (SNCR mechanism which eliminates single-node clusters and then improve energy efficiency. In this paper, we show that MaxMin, because of its original pathological case, does not support the grid deployment topology, which is frequently used in WSN architectures. The unreliability feature of the wireless links could have negative impacts on Link Quality Indicator (LQI based clustering protocols. So, in the second part of this paper we show how our distributed Link Quality based d- Clustering Protocol (LQI-DCP has good performance in both stable and high unreliable link environments. Finally, performance evaluation results also show that LQI-DCP fully supports the grid deployment topology and is more energy efficient than MaxMin.

    This report details the feasibility of a field deployable DNA analyzer. Steps for swabbing cells from surfaces and extracting DNA in an automatable way are presented. Since enzymatic amplification reactions are highly sensitive to environmental contamination, sample preparation is a crucial step to make an autonomous deployable instrument. We perform sample clean up and concentration in a flow through packed bed. For small initial samples, whole genome amplification is performed in the packed bed resulting in enough product for subsequent PCR amplification. In addition to DNA, which can be used to identify a subject, protein is also left behind, the analysis of which can be used to determine exposure to certain substances, such as radionuclides. Our preparative step for DNA analysis left behind the protein complement as a waste stream; we determined to learn if the proteins themselves could be analyzed in a fieldable device. We successfully developed a two-step lateral flow assay for protein analysis and demonstrate a proof of principle assay.

    To explore central challenges with translating self-reported measurement tools for functional status and health-related quality of life (HRQOL) into ambulatory quality indicators for older people with multiple chronic conditions (MCCs). Review. Sources including the National Quality Measures Clearinghouse and National Quality Forum were reviewed for existing ambulatory quality indicators relevant to functional status, HRQOL, and people with MCCs. Seven informants with expertise in indicators using functional status and HRQOL. Informant interviews were conducted to explore knowledge about these types of indicators, particularly usability and feasibility. Nine important existing indicators were identified in the review. For process, identified indicators addressed whether providers assessed functional status; outcome indicators addressed quality of life. In interviews, informants agreed that indicators using self-reported data were important in this population. Challenges identified included concerns about usability due to inability to discriminate quality of care adequately between organizations and feasibility concerns regarding high data collection burden, with a correspondingly low response rate. Validity was also a concern because evidence is mixed that healthcare interventions can improve HRQOL or functional status for this population. As a possible first step, a structural standard could be systematic collection of these measures in a specific setting. Although functional status and HRQOL are important outcomes for older people with MCCs, few relevant ambulatory quality indicators exist, and there are concerns with usability, feasibility, and validity. Further research is needed on how best to incorporate these outcomes into quality indicators for people with MCCs. © Published 2013.

The functional balance was measured using the berg balance scale and timed up and go test. The relationship among the outcome measure was found out using the Pearson correlation coefficient. Results: The results of the present study showed that EFPT and BBS are negatively correlated to each other with r-value -0.271. The educational status score showed a low positive correlation with functional balance with r-value 0.358. The quality of life did not show any significant correlation with functional balance. Interpretation & Conclusion: Executive function and functional balance showed a low correlation. This means that higher the executive function, better will be the functional balance of the individual. Moreover, educational status also affects the functional balance of the individual.

    Kegg, Colleen M.

    1988-01-01

    A deployable structure which meets stringent thermal and strength requirements in a space environment was developed. A mast with a very low coefficient of thermal expansion (CTE) was required to limit the movement from thermal distortion over the temperature range of -200 C to 80 C to .064 cm (.025 in). In addition, a high bending strength over the temperature range and weight less than 18.1 kg (40 lbs) was needed. To meet all of the requirements, a composite, near-zero CTE structure was developed. The measured average CTE over the temperature range for the mast was .70 x .000001/C (.38 x .000001/F). The design also has the advantage of being adjustable to attain other specific CTE if desired.

  1. Complex Deployed Responsive Service

    Science.gov (United States)

    Parry, Glenn; McLening, Marc; Caldwell, Nigel; Thompson, Rob

    A pizza restaurant must provide product, in the form of the food and drink, and service in the way this is delivered to the customer. Providing this has distinct operational challenges, but what if the restaurant also provides a home delivery service? The service becomes deployed as the customer is no-longer co-located with the production area. The business challenge is complicated as service needs to be delivered within a geographic region, to time or the pizza will be cold, and within a cost that is not ­prohibitive. It must also be responsive to short term demand; needing to balance the number of staff it has available to undertake deliveries against a forecast of demand.

    2016-10-01

    This paper presents a concept of deployable Pipe-Z (dPZ): a modular structural system which takes advantage of the robustness of rigid-panel mechanism and allows to create free-form links which are also reconfigurable and deployable. The concept presented can be applied for building habitats and infrastructures for human exploration of oceans and outer space. dPZ structures can adapt to changing requirements e.g. mission objectives, crew condition and technological developments. Furthermore, such lightweight and adaptable structural concept can assist in sustainable exploration development. After brief introduction, the concept of Pipe-Z (PZ) is presented. Next, the reconfigurability of PZ is explained and illustrated with continuous and collision-free transition from a PZ forming a Trefoil knot to a Figure-eight knot. The following sections introduce, explain and illustrate the folding mechanism of a single foldable Pipe-Z module (fPZM) and entire dPZ structure. The latter is illustrated with asynchronous (delayed) unfolding of a relatively complex Unknot. Several applications of PZ are suggested, namely for underwater and deep-space and surface habitats, for permanent, but in particular, temporary or emergency passages. As an example, a scenario of a failure of one of the modules of the International Space Station is presented where a rigid structure of 40 fPZMs bypasses the "dead link". A low-fidelity prototype of a 6-module octagonal dPZ is presented; several folding schemes including concentric toric rings are demonstrated. Practical issues of pressurization and packing are briefly discussed.

  5. Design optimization of deployable wings

    Science.gov (United States)

    Gaddam, Pradeep

    Morphing technology is an important aspect of UAV design, particularly in regards to deployable systems. The design of such system has an important impact on the vehicle's performance. The primary focus of the present research work was to determine the most optimum deployable wing design from 3 competing designs and develop one of the deployable wing designs to test in the research facility. A Matlab code was developed to optimize 3 deployable wing concepts inflatable, inflatable telescopic and rigid-folding wings based on a sequential optimization strategy. The constraints that were part of the code include the packaging constraints during its stowed state, fixed length of the deployed section and the minimum L/D constraint. This code resulted in determining the optimum weight of all the 3 designs, the most optimum weight design is the inflatable wing design. This is a result of the flexible skin material and also due to no rigid parts in the deployed wing section. Another goal of the research involved developing an inflatable telescopic wing. The prototype was tested in a wind tunnel, while the actual wing was tested in the altitude chamber to determine the deployment speed, input pressure, analyze and predict the deployment sequence and behavior of the wing at such high wind speeds and altitudes ranging from 60,000 ft to 90,000 ft. Results from these tests allowed us to conclude the deployment sequence of the telescopic wing followed from the root to the tip section. The results were used to analyze the deployment time of the wing. As expected the deployment time decreased with an increase in input pressure. The results also show us that as the altitude increases, the deployment speed of the wing also increased. This was demonstrated when the wing was tested at a maximum altitude pressure of 90,000ft, well above the design altitude of 60,000ft.

    An analysis of the Strehl ratio and the optical transfer function as imaging quality parameters of optical elements with enhanced focal length is carried out by employing the Wigner distribution function. To this end, we use four different pupil functions: a full circular aperture, a hyper-Gaussian aperture, a quartic phase plate, and a logarithmic phase mask. A comparison is performed between the quality parameters and test images formed by these pupil functions at different defocus distances.

  10. Deployable Fresnel Rings

    Kennedy, Timothy F.; Fink, Patrick W.; Chu, Andrew W.; Lin, Gregory Y.

    2014-01-01

    Deployable Fresnel rings (DFRs) significantly enhance the realizable gain of an antenna. This innovation is intended to be used in combination with another antenna element, as the DFR itself acts as a focusing or microwave lens element for a primary antenna. This method is completely passive, and is also completely wireless in that it requires neither a cable, nor a connector from the antenna port of the primary antenna to the DFR. The technology improves upon the previous NASA technology called a Tri-Sector Deployable Array Antenna in at least three critical aspects. In contrast to the previous technology, this innovation requires no connector, cable, or other physical interface to the primary communication radio or sensor device. The achievable improvement in terms of antenna gain is significantly higher than has been achieved with the previous technology. Also, where previous embodiments of the Tri-Sector antenna have been constructed with combinations of conventional (e.g., printed circuit board) and conductive fabric materials, this innovation is realized using only conductive and non-conductive fabric (i.e., "e-textile") materials, with the possible exception of a spring-like deployment ring. Conceptually, a DFR operates by canceling the out-of-phase radiation at a plane by insertion of a conducting ring or rings of a specific size and distance from the source antenna, defined by Fresnel zones. Design of DFRs follow similar procedures to those outlined for conventional Fresnel zone rings. Gain enhancement using a single ring is verified experimentally and through computational simulation. The experimental test setup involves a microstrip patch antenna that is directly behind a single-ring DFR and is radiating towards a second microstrip patch antenna. The first patch antenna and DFR are shown. At 2.42 GHz, the DFR improves the transmit antenna gain by 8.6 dB, as shown in Figure 2, relative to the wireless link without the DFR. A figure illustrates the

  11. Muscle quality in aging: a multi-dimensional approach to muscle functioning with applications for treatment.

    Fragala, Maren S; Kenny, Anne M; Kuchel, George A

    2015-05-01

    Aging is often accompanied by declines in physical functioning which impedes older adults' quality of life, sense of independence, and ability to perform daily tasks. Age-related decreases in skeletal muscle quantity, termed sarcopenia, have traditionally been blamed for these physical decrements. However, recent evidence suggests that the quality of muscle tissue may be more functionally relevant than its quantity. 'Muscle quality' has been emerging as a means to elucidate and describe the intricate intramuscular changes associated with muscle performance in the context of aging and sarcopenia. While muscle quality has most commonly been defined in terms of muscle composition or relative strength, at the core, muscle quality really describes muscle's ability to function. Skeletal muscle displays a strong structure-function relationship by which several architectural characteristics factor into its functional capacity. This review describes the structural, physiological, and functional determinants of muscle quality at the tissue and cellular level, while also introducing other novel parameters such as sarcomere spacing and integrity, circulating biomarkers, and the muscle quality index. Muscle qualitative features are described from the perspective of how physical exercise may improve muscle quality in older adults. This broad, multidimensional perspective of muscle quality in the context of aging and sarcopenia offers comprehensive insights for consideration and integration in developing improved prognostic tools for research and clinical care, while also promoting translational approaches to the design of novel targeted intervention strategies designed to maintain function and mobility into late life.

  16. Towards Deployable DDoS Defense for Web Applications

    CERN Document Server

    Mittal, Prateek; Hu, Yih-Chun; Caesar, Matthew

    2011-01-01

    Distributed Denial of Service (DDoS) attacks form one of the most serious threats that plague the Internet today. However, despite over a decade of research, and the existence of several proposals to address this problem, there has been little progress to date on actual adoption. In this work, we argue that adoption would be simplified by lowering the cost of deployment. Towards this goal, we present Mirage, an approach to DDoS defense that lowers the cost of adoption. Mirage achieves comparable performance to other DDoS mitigation schemes while providing benefits when deployed only in the server's local network and its upstream ISP, where local business objectives may incentivize deployment. In particular, Mirage does not require source end hosts to install any software to access Mirage protected websites. Unlike previous proposals, Mirage only requires functionality from routers that is already deployed in today's routers, though this functionality may need to be scaled depending on the point of deployment....

  17. Deployment simulation of a deployable reflector for earth science application

    2015-10-01

    A novel mission concept namely NEXRAD-In-Space (NIS) has been developed for monitoring hurricanes, cyclones and other severe storms from a geostationary orbit. It requires a space deployable 35-meter diameter Ka-band (35 GHz) reflector. NIS can measure hurricane precipitation intensity, dynamics and its life cycle. These information is necessary for predicting the track, intensity, rain rate and hurricane-induced floods. To meet the requirements of the radar system, a Membrane Shell Reflector Segment (MSRS) reflector technology has been developed and several technologies have been evaluated. However, the deployment analysis of this large size and high-precision reflector has not been investigated. For a pre-studies, a scaled tetrahedral truss reflector with spring driving deployment system has been made and tested, deployment dynamics analysis of this scaled reflector has been performed using ADAMS to understand its deployment dynamic behaviors. Eliminating the redundant constraints in the reflector system with a large number of moving parts is a challenging issue. A primitive joint and flexible struts were introduced to the analytical model and they can effectively eliminate over constraints of the model. By using a high-speed camera and a force transducer, a deployment experiment of a single-bay tetrahedral module has been conducted. With the tested results, an optimization process has been performed by using the parameter optimization module of ADAMS to obtain the parameters of the analytical model. These parameters were incorporated to the analytical model of the whole reflector. It is observed from the analysis results that the deployment process of the reflector with a fixed boundary experiences three stages. These stages are rapid deployment stage, slow deployment stage and impact stage. The insight of the force peak distributions of the reflector can help the optimization design of the structure.

  18. The relationship between motor function, cognition, independence and quality of life in myelomeningocele patients

    Full Text Available ABSTRACT Motor function, cognition, functional independence and quality of life have been described in myelomeningocele patients, but no study has investigated their relationships. We aimed to investigate the relationships between motor function, cognition, functional independence, quality of life, age, and lesion level in myelomeningocele patients, and investigate the influence of hydrocephalus on these variables. We assessed 47 patients with the Gross Motor Function Measure (motor function, Raven’s Colored Progressive Matrices (cognition, Pediatric Evaluation of Disability Inventory (functional independence and the Autoquestionnaire Qualité de vie Enfant Imagé (quality of life. Spearman’s correlation tests determined relationships between the variables. The Friedman ANOVAs determined the influence of hydrocephalus. Motor function was strongly related to mobility and lesion level, and moderately related to cognition, self-care and social function. Cognition and quality of life were moderately related to functional independence. Age correlated moderately with functional independence and quality of life. Hydrocephalus resulted in poorer motor/cognitive outcomes and lower functional independence.

    2004-01-01

    A new method was proposed for quasi-static deployment analysis of deployable space truss structures. The structure is assumed a rigid assembly, whose constraints are classified as three categories:rigid member constraint, joint-attached kinematic constraint and boundary constraint. And their geometric constraint equations and derivative matrices are formulated. The basis of the null space and M-P inverse of the geometric constraint matrix are employed to determine the solution for quasi-static deployment analysis. The influence introduced by higher terms of constraints is evaluated subsequently. The numerical tests show that the new method is efficient.

    Directory of Open Access Journals (Sweden)

    Wendy Chui Phing Lau

    2015-10-01

    Full Text Available After yield, quality is one of the most important aspects of rice breeding. Preference for rice quality varies among cultures and regions; therefore, rice breeders have to tailor the quality according to the preferences of local consumers. Rice quality assessment requires routine chemical analysis procedures. The advancement of molecular marker technology has revolutionized the strategy in breeding programs. The availability of rice genome sequences and the use of forward and reverse genetics approaches facilitate gene discovery and the deciphering of gene functions. A well-characterized gene is the basis for the development of functional markers, which play an important role in plant genotyping and, in particular, marker-assisted breeding. In addition, functional markers offer advantages that counteract the limitations of random DNA markers. Some functional markers have been applied in marker-assisted breeding programs and have successfully improved rice quality to meet local consumers’ preferences. Although functional markers offer a plethora of advantages over random genetic markers, the development and application of functional markers should be conducted with care. The decreasing cost of sequencing will enable more functional markers for rice quality improvement to be developed, and application of these markers in rice quality breeding programs is highly anticipated.

    2017-04-01

    Clinical symptoms and sociodemographic variables predict level of functioning and quality of life in patients with schizophrenia. However, few studies have examined the effect of personality traits on quality of life and overall functioning in schizophrenia. Personality traits are premorbid to illness and may predict the way patients experience schizophrenia. The aim of this study was to examine the individual and additive effects of two core personality traits-neuroticism and extraversion-on quality of life and functioning. Patients with schizophrenia-spectrum disorders (n=153) and healthy controls (n=125) completed personality and quality of life questionnaires. Global functioning was assessed during a clinician-administered structured interview. Neuroticism and extraversion scores were analyzed both as continuous variables and as categorical extremes (High versus Normal Neuroticism, Low versus Normal Extraversion). Quality of life was significantly associated with neuroticism, extraversion, and the neuroticism×diagnosis and extraversion×diagnosis interactions. For patients, a lower neuroticism score (in the normal range) was associated with quality of life scores comparable to controls; whereas high neuroticism scores in patients were associated with the lowest quality of life. For overall functioning, only diagnosis had a significant effect. Neuroticism modulates quality of life and may provide an important key to improving the life of patients with schizophrenia.

  9. THE CONCEPT OF QUALITY IN THE FUNCTION OF SECONDARY HEALTH CARE

    Directory of Open Access Journals (Sweden)

    Agneza Aleksijević

    2017-01-01

    Full Text Available Te paper brings an overview of basic approaches to the concept of quality and quality management in order to improve secondary health care. We observe the concept of quality from the perspective of accreditation, categorization and certification of health institutions in the secondary health care. Quality health care is one that meets the needs of users and professional needs, achieves its goals and uses resources in the most efficient manner. Quality in health care is an example of good practice of adopting and improving standards, processes and outcomes. Improving quality requires knowledge and skills with an emphasis on lifelong learning and adjustment to patient’s needs and values. Quality is the responsibility of all individuals within the organization. Poor quality is expensive because of the inaction of people within the system. Te Heath Care Quality Act has determined the principles and the system of measures for achieving and improving quality. These are the measures for achieving quality health care and the implementation of the principles of efficiency and effectiveness of the quality of health care procedures at all levels of health care, the principles of orientation to the patient as well as the principle of patient safety. Te implementation of quality systems results in some new expenditures and every expense incurred is in the function of creation and production of goods and services. In medical institutions we provide health services and thus achieve income. Expenses have to be calculated into the price if we want to generate profit.

    2010-04-01

    To investigate the sexual function and the quality of sexual life in patients with chronic prostatitis (CP), and to analyze the correlated factors and their influence on the quality of life (QOL) of the CP patients. We randomly selected 148 CP patients as the CP group and 71 healthy men as controls, asked them to fill out a questionnaire on sexual function and the quality of sexual life, obtained their scores on NHI-CPSI, and comparatively analyzed the results. We also made analyses on the influence of age, disease course, CP symptom scores and EPS level on sexual function and the quality of sexual life, as well as the impact of CP symptoms, sexual dysfunction and sexual life quality on the QOL of the CP patients. No retro-ejaculation was found in either of the two groups. The mean score on sexual function and sexual life quality was 38.1 +/- 7.9 and 47.8 +/- 3.1 in the CP and the control group, respectively, with statistically significant differences (P patients showed significantly decreased scores on libido, erectile function, ejaculation, orgasm frequency, self-confidence in sexual life, sexual satisfaction, and the partners' orgasm frequency and sexual satisfaction (P prostatic fluid. The age of the patients was significantly correlated with the score of libido but not with other indexes of sexual function. CP symptoms, including pain, micturition and reduced sexual function and sexual life quality, along with the decreased orgasm frequency and sexual satisfaction of the patients' spouses, remarkably influenced the patients' QOL. CP symptoms significantly decrease the indexes of sexual function of the patients and, in turn, their sexual life quality and QOL. Sexual dysfunction and reduced sexual life quality of CP patients are significantly correlated with CP symptoms, but not with the course of the disease, the age of the patient and the results of EPS detection.

  11. Facility Deployment Decisions through Warp Optimizaton of Regressed Gaussian Processes

    CERN Document Server

    Scopatz, Anthony

    2015-01-01

    A method for quickly determining deployment schedules that meet a given fuel cycle demand is presented here. This algorithm is fast enough to perform in situ within low-fidelity fuel cycle simulators. It uses Gaussian process regression models to predict the production curve as a function of time and the number of deployed facilities. Each of these predictions is measured against the demand curve using the dynamic time warping distance. The minimum distance deployment schedule is evaluated in a full fuel cycle simulation, whose generated production curve then informs the model on the next optimization iteration. The method converges within five to ten iterations to a distance that is less than one percent of the total deployable production. A representative once-through fuel cycle is used to demonstrate the methodology for reactor deployment.

    The paper examines the benefit of bread enriched with antioxidants on oxidative stress, and on the quantities of hydrosoluble antioxidants in a group of human subjects. The home-management of functional foods strategy seeks to improve prompt and effective basic nutrition using additional attributes that are directly positively beneficial for health and well-being. The purpose of this clinical study was to test the tolerance and benefits of multicomponent functional foods enriched with antioxidant compounds obtained from plant extracts on healthy adult volunteers. A detailed protocol was created to formalize and standardize the procedures for data collection, e.g. filling out standardized forms and functional diet questionnaires. For the research method, Group A was given the special diet enriched with multicomponent antioxidant foods and Group B (control). The data were analysed using the quantitative methods. They showed significant increase of hydrosoluble antioxidants in group A compared to control, from 220.61+/-27.92 - 313.56+/-37.09 micrograms/mL (p=0.05), compared to 280.47+/-32.1 - 238.27+/-44.93 micrograms/mL (p=0.45). Also, oxidative stress values showed a decrease in the diet group compared to control that reached statistical significance. Oxidative stress decreased in the diet group to 244 +/- 89 compared to 308+/-108 UFORT in the control group. The responses of the prevention of chronic diseases to a functional foods strategy depend on how they are absorbed and utilized in the body. An anti-oxidant diet with natural bioactive components could become an interesting solution for degenerative disorders in which oxidative stress is increased.

    Military deployment to Southwest Asia since 2003 in support of Operations Enduring Freedom/Iraqi Freedom/New Dawn has presented unique challenges from a pulmonary perspective. Various airborne hazards in the deployed environment include suspended geologic dusts, burn pit smoke, vehicle exhaust emissions, industrial air pollution, and isolated exposure incidents. These exposures may give rise to both acute respiratory symptoms and in some instances development of chronic lung disease. While increased respiratory symptoms during deployment are well documented, there is limited data on whether inhalation of airborne particulate matter is causally related to an increase in either common or unique pulmonary diseases. While disease processes such as acute eosinophilic pneumonia and exacerbation of preexisting asthma have been adequately documented, there is significant controversy surrounding the potential effects of deployment exposures and development of rare pulmonary disorders such as constrictive bronchiolitis. The role of smoking and related disorders has yet to be defined. This article presents the current evidence for deployment-related respiratory symptoms and ongoing Department of Defense studies. Further, it also provides general recommendations for evaluating pulmonary health in the deployed military population.

    For many years, software quality assurance lagged behind hardware quality assurance in terms of methods, metrics, and successful results. New approaches such as Quality Function Deployment (QFD) the ISO 9000-9004 standards, the SEI maturity levels, and Total Quality Management (TQM) are starting to attract wide attention, and in some cases to bring software quality levels up to a parity with manufacturing quality levels. Since software is on the critical path for many engineered products, and for internal business systems as well, the new approaches are starting to affect global competition and attract widespread international interest. It can be hypothesized that success in mastering software quality will be a key strategy for dominating global software markets in the 21st century.

    Circular dichroism (CD) is a non-destructive and powerful technique for providing structure and ligand interaction information of small molecules as well as biotechnological medicines. While CD is a well-established technique in biomedical research, and different types and variants of CD do exist, the focus of this review is on the pharmaceutical quality control (QC) aspects of the classic electronic CD (ECD). The basic principles of the CD technique are initially described, followed by a systematic literature research on pharmaceutical aspects encompassing chiral small molecules, bio-polymers (i.e. proteins, peptides and nucleic acids), medicine-biotarget interaction (i.e. small molecule-albumin interaction, protein-receptor interaction and peptide-biotarget interaction) and medicine changes (i.e. chemical modification, biosimilar/bio-better with stability and aggregation). In addition, unstructured literature was also included covering the use of CD mainly in discovery and fundamental research, but which might shift towards the pharmaceutical QC field as well in the future.

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

    High quality means good fitness for the intended use. Research activity regarding quality measures for platelet transfusions has focused on platelet storage and platelet storage lesion. Thus, platelet quality is judged from the manufacturer's point of view and regulated to ensure consistency and stability of the manufacturing process. Assuming that fresh product is always superior to aged product, maintaining in vitro characteristics should preserve high quality. However, despite the highest in vitro quality standards, platelets often fail in vivo. This suggests we may need different quality measures to predict platelet performance after transfusion. Adding to this complexity, platelets are used clinically for very different purposes: platelets need to circulate when given as prophylaxis to cancer patients and to stop bleeding when given to surgery or trauma patients. In addition, the emerging application of platelet-rich plasma injections exploits the immunological functions of platelets. Requirements for quality of platelets intended to prevent bleeding, stop bleeding, or promote wound healing are potentially very different. Can a single measurable characteristic describe platelet quality for all uses? Here we present microparticle measurement in platelet samples, and its potential to become the universal quality characteristic for platelet production, storage, viability, function, and compatibility.

    The health-related quality of life of school-aged children with high-functioning autism is poorly understood. The objectives of this study were to compare the health-related quality of life of children with high-functioning autism to that of typically developing peers and to compare child-self and parent-proxy reports of health-related quality of life of children. A cross-sectional study of children with high-functioning autism (n = 30) and peers (n = 31) was conducted using the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Children with high-functioning autism had significantly poorer health-related quality of life than peers whether reported by themselves (p autism as compared to a sample of peers, from the child's perspective. It strengthens earlier findings that children with high-functioning autism experience poorer health-related quality of life than those without this disorder and points to the importance of clinicians working with families to identify areas in a child's life that promote or hinder their sense of well-being.

    BACKGROUND: A living donor transplant improves the survival and quality of life of a transplant patient. However, the impact of transplantation on postoperative lung function and respiratory muscular strength in kidney donors remains unknown. OBJECTIVE: To evaluate pulmonary function, respiratory muscle strength, quality of life and the incidence of postoperative pulmonary complications (PPCs) in kidney donors undergoing nephrectomy. METHOD: This prospective cohort enrolled 110 consecutive kidney donors undergoing nephrectomy. Subjects underwent pulmonary function (using spirometry) and respiratory muscular strength (using manovacuometry) assessments on the day prior to surgery and 1, 2, 3 and 5 days postoperatively. Quality of life (measured by the SF-36) was evaluated preoperatively and 30 days postoperatively. PPCs were assessed daily by a blinded assessor. RESULTS: Donors exhibited a decrease of 27% in forced vital capacity, 58% in maximum inspiratory capacity and 51% in maximum expiratory pressure on the 1stpostoperative day (p<0.001) but this improved over days 2, 3 and 5 but had not returned to preoperative levels. Patient quality of life was still impaired at 30 days with regards to functional capacity, physical role, pain, vitality and social functioning (p<0.05) but these parameters improved slowly. None of the patients developed PPCs. CONCLUSION: Kidney donors submitted to nephrectomy exhibited a reduction in pulmonary function, respiratory muscular strength and quality of life, most of which were improving toward pre-surgical levels.

    Full Text Available Background/Aim. Upper limb lymphedema is one of the most frequent chronic complications after breast cancer treatment with a significant impact on the upper extremity function and quality of life (QoL. The aim of this study was to estimate health-related quality of life (HRQoL in patients with breast-cancer-related lymphedema and its correlation with upper limb function and the size of edema. Methods. The cross-sectional study included 54 breast-cancer-related lymphedema patients. The quality of life was evaluated by the Short Form 36-Item Health Survey (SF-36. Upper limb function was assessed by the Quick Disability of the Arm, Shoulder and Hand questionnaire (Quick DASH. The size of lymphedema was determined by the arm circumference. Results. The higher HRQoL score was assessed for mental health (47.0 ± 12.2 than for physical one (42.2 ± 7.5. The highest values of SF-36 were found in the domains of Mental Health (67.7 ± 22.9 and Social Function (70.1 ± 23.1. The lowest scores were registered in the domains of Role Physical (46.9 ± 39.1 and General Health (49.3 ± 20.1. Upper extremity function statistically significantly correlated with the domains Role Physical, Bodily Pain and Physical Composite Summary and also, with the domain Role Emotional (p 0.05. Conclusions. Physical disability in patients with breast cancer-related lymphedema influences quality of life more than mental health. Upper limb function has a significant impact on quality of life, not only on the physical, but also on the mental component. The presence of breast-cancer-related lymphedema certainly affects upper limb function and quality of life, but in this study no significant correlation between the size of edema and quality of life was found.

    The 5-meter technology antenna program demonstrated the overall feasibility of integrating a mesh reflector surface with a deployable truss structure to achieve a precision surface contour compatible with future, high-performance antenna requirements. Specifically, the program demonstrated: the feasibility of fabricating a precision, edge-mounted, deployable, tetrahedral truss structure; the feasibility of adjusting a truss-supported mesh reflector contour to a surface error less than 10 mils rms; and good RF test performance, which correlated well with analytical predictions. Further analysis and testing (including flight testing) programs are needed to fully verify all the technology issues, including structural dynamics, thermodynamics, control, and on-orbit RF performance, which are associated with large, deployable, truss antenna structures.

    To describe the adaptive behavior and functional outcomes, and health-related quality of life of children who were urgently admitted to the ICU. Prospective observational study. Critical Care Medicine program at a University-affiliated pediatric institution. Urgently admitted patients, aged 1 month to 18 yrs. None. We evaluated children's adaptive behavior functioning with the Vineland Adaptive Behavior Scale-2, functional outcomes with the pediatric cerebral performance category and pediatric overall performance category, and health-related quality of life with the Pediatric Quality of Life Inventory 4 and Visual Analogue Scale. We enrolled 91 children and 65 (71%) completed the 1-month assessment. Patients had a mean (SD) Vineland Adaptive Behavior Scale-2 rating of 83.2 (± 24.8), considered to be moderate-low adaptive behavior functioning. From baseline to 1 month, pediatric cerebral performance category ratings did not significantly change (p = 0.59) and pediatric overall performance category ratings significantly improved (p = 0.03). Visual Analogue Scale ratings significantly worsened from baseline to 1 wk (p adaptive behavior functioning. Neurological admissions, worse pediatric cerebral performance category score at baseline, longer ICU stay, and longer duration of extracorporeal membrane oxygenation were independently associated with worse functional outcome. Worse pediatric cerebral performance category score at baseline, longer ICU stay, and longer duration of extracorporeal membrane oxygenation were independently associated with worse health-related quality of life. Children surviving PICU have significant adaptive behavior functioning and functional morbidity and reduced health-related quality of life. Although neurologic morbidity following ICU was associated with baseline state, we found that resuscitation intensity and illness severity factors were independently associated with the development of acquired brain injury and reduced quality of life.

    Robin L Aupperle

    Full Text Available BACKGROUND: Combat-related PTSD has been associated with reduced gray matter volume in regions of the prefrontal and temporal cortex, hippocampus, insula, and amygdala. However, the relationship between gray matter volume and specific deployment and post-deployment experiences has not been investigated. The aim of this study was to delineate how such experiences may contribute to structural brain changes for combat veterans. METHODS: Operation Iraqi Freedom/Operation Enduring Freedom veterans (N = 32 completed magnetic resonance imaging, the Deployment Risk and Resilience Inventory, Alcohol Use Disorders Identification Test, and Clinical Administered PTSD Scale. Voxel-wise Huber robust multiple regressions were used to quantify the relationship between gray matter volume and deployment experiences (combat experiences, military social support and post-deployment symptoms (PTSD, alcohol use. RESULTS: There was an interaction between severity of combat experiences and military social support for orbitofrontal gyrus gray matter volume. Specifically, individuals with more orbitofrontal gyrus gray matter volume reported less combat experiences and higher unit support. Individuals with more severe PTSD symptoms showed reduced gray matter volume within a large temporal region (inferior temporal and parahippocampal gyrus. CONCLUSIONS: The identified association between unit support and orbitofrontal gyrus volume supports two potential resilience mechanisms to be delineated with future longitudinal studies. First, individuals with larger orbitofrontal gyrus may engage in greater quality of social interactions and thus experience combat as less stressful. Second, individuals who experience greater unit support may preserve a larger orbitofrontal gyrus, serving to "protect" them from aversive consequences of combat.

    Footdale, Joseph N.; Murphey, Thomas W.

    2014-01-01

    The detailed mechanical design of a novel deployable support structure that positions and tensions a membrane optic for space imagining applications is presented. This is a complex three-dimensional deployment using freely deploying rollable composite tape spring booms that become load bearing structural members at full deployment. The deployment tests successfully demonstrate a new architecture based on rolled and freely deployed composite tape spring members that achieve simultaneous deployment without mechanical synchronization. Proper design of the flexible component mounting interface and constraint systems, which were critical in achieving a functioning unit, are described. These flexible composite components have much potential for advancing the state of the art in deployable structures, but have yet to be widely adopted. This paper demonstrates the feasibility and advantages of implementing flexible composite components, including the design details on how to integrate with required traditional mechanisms.

  14. A Bayesian Framework for Reliability Analysis of Spacecraft Deployments

    Evans, John W.; Gallo, Luis; Kaminsky, Mark

    2012-01-01

    Deployable subsystems are essential to mission success of most spacecraft. These subsystems enable critical functions including power, communications and thermal control. The loss of any of these functions will generally result in loss of the mission. These subsystems and their components often consist of unique designs and applications for which various standardized data sources are not applicable for estimating reliability and for assessing risks. In this study, a two stage sequential Bayesian framework for reliability estimation of spacecraft deployment was developed for this purpose. This process was then applied to the James Webb Space Telescope (JWST) Sunshield subsystem, a unique design intended for thermal control of the Optical Telescope Element. Initially, detailed studies of NASA deployment history, "heritage information", were conducted, extending over 45 years of spacecraft launches. This information was then coupled to a non-informative prior and a binomial likelihood function to create a posterior distribution for deployments of various subsystems uSing Monte Carlo Markov Chain sampling. Select distributions were then coupled to a subsequent analysis, using test data and anomaly occurrences on successive ground test deployments of scale model test articles of JWST hardware, to update the NASA heritage data. This allowed for a realistic prediction for the reliability of the complex Sunshield deployment, with credibility limits, within this two stage Bayesian framework.

    Schizophrenia is a chronic illness that negatively affects the quality of life and psychosocial functions. Defined criteria to assess remission in schizophrenia are considered to be useful in the long-term follow-up of patients and in discriminating diagnostic factors. This study investigated the quality of life and functionality in schizophrenia patients in symptomatic remission (R-Sch) and not in remission (Non-R-Sch). Sociodemographic data were collected for 40 R-Sch and 40 Non-R-Sch patients, and the following scales were administered: the Clinical Global Impression-Severity (CGI-S) Scale; Positive and Negative Syndrome Scale (PANSS), World Health Organization Quality of Life Questionnaire-Short Form, Turkish Version (WHOQOL-BREF-TR), Quality of Life Scale for Schizophrenia Patients (QLS), and Global Assessment of Functioning Scale (GAF). The total and all subscale scores of PANSS and the CGI-S score were significantly lower in the R-Sch group than in the Non-R-Sch group, whereas the GAF scores and all subscales of QLS and WHOQOL-BREF-TR were significantly higher. This study demonstrates that improvement in symptoms in schizophrenia patients improves quality and functionality in all areas of life, suggesting that an improvement in symptoms is the most important determinant of functional recovery in the treatment of schizophrenia.

    Wireless sensor networks (WSNs) are among the most promising technologies of the new millennium. The opportunities afforded by being able to program networks of small, lightweight, low-power, computation- and bandwidth-limited nodes have attracted a large community of researchers and developers. However, the unique set of capabilities offered by the technology produces an exciting but complex design space, which is often difficult to negotiate in an application context. Deploying sensing physical environments produces its own set of challenges, and can push systems into failure modes, thus revealing problems that can be difficult to discover or reproduce in simulation or the laboratory. Sustained efforts in the area of wireless networked sensing over the last 15 years have resulted in a large number of theoretical developments, substantial practical achievements, and a wealth of lessons for the future. It is clear that in order to bridge the gap between (on the one hand) visions of very large scale, autonomous, randomly deployed networks and (on the other) the actual performance of fielded systems, we need to view deployment as an essential component in the process of developing sensor networks: a process that includes hardware and software solutions that serve specific applications and end-user needs. Incorporating deployment into the design process reveals a new and different set of requirements and considerations, whose solutions require innovative thinking, multidisciplinary teams and strong involvement from end-user communities. This special feature uncovers and documents some of the hurdles encountered and solutions offered by experimental scientists when deploying and evaluating wireless sensor networks in situ, in a variety of well specified application scenarios. The papers specifically address issues of generic importance for WSN system designers: (i) data quality, (ii) communications availability and quality, (iii) alternative, low-energy sensing

    2013-09-01

    Quality management (QM) is primarily an in-house executive function. It conduces to ensure a high quality service and has the external object to satisfy customer expectations. In Germany the implementation of quality management systems (QMS) is made compulsory for all medical facilities by law. However, details are not regulated and there is no need to certify the in-house QMS. Within the last 10 years many pathology institutions have become certified or accredited and have implemented voluntary measures of external quality assurance, such as quality circles and round robin trials. For non-certified institutions it might be helpful to be guided by established QM standards like the ISO 9001:2008. The fundamental concepts of QM, some pathology-specific aspects and some implications for the professional associations are discussed in this article.

    To examine the association of personality traits and characteristics on quality of life and functioning in adults with ADHD. Participants were adults with (n = 206) and without ADHD (n = 123) who completed the Temperament and Character Inventory (TCI), the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), and the Social Adjustment Scale-Self-Report (SAS-SR). Participants also provided information on academic, motor vehicle operation, legal, social, familial, and occupational functioning. Outcomes were examined using stepwise linear regression, logistic regression (for binary outcomes), and negative binomial regression (for count outcomes) controlling for ADHD symptoms, psychiatric comorbidity, and executive dysfunction. Adults with ADHD significantly differed from controls across nearly all TCI personality domains. On average, adults with ADHD endorsed more novelty seeking, harm avoidance, and self-transcendence, and less reward dependence, persistence, self-directedness, and cooperativeness. Personality traits and characteristics, especially self-directedness, significantly predicted functional impairments even after controlling for ADHD symptoms, executive function deficits, and current psychiatric comorbidities. In adults with ADHD, personality traits exert unique associations on quality of life and functional impairment across major life domains, beyond the relations expected of and associated with ADHD symptoms and other associated psychiatric conditions and cognitive vulnerabilities. Addressing personality traits in adults with ADHD may lead to improvements in quality of life and reductions in functional impairment. © The Author(s) 2015.

    2010-04-01

    Restoration of quality of life is considered as the ultimate treatment goal in the management of schizophrenia and is important for destigmatising the disease. However, few studies, including the most recent, have collected quality of life data prospectively or evaluated the relationship of treatment with quality of life. Amisulpride is an atypical antipsychotic drug which has been described to have potency in improving negative symptoms of chronic schizophrenia and whose use is associated with a relatively low rate of emergence of extrapyramidal side-effects. These properties may contribute to a beneficial effect on quality of life. A systematic literature review of functional outcome in clinical trials with amisulpride was performed in order to assess the effect of this drug on quality of life and social functioning in patients. The Medline database was searched for all studies of amisulpride in schizophrenia which reported functional and quality of life outcomes up until 30 September 2009. Only one dedicated study assessing functional outcome or quality of life as a primary outcome criterion was identified. This demonstrated significant improvement in subjective well-being in patients with schizophrenia initiating treatment with amisulpride, and a correlation between this improvement and amelioration of psychopathology. In addition, functional outcome rating scales were used as secondary outcome measures in eight randomised clinical trials, and two naturalistic observational studies. Amisulpride treatment was associated with improvement in functional outcome, with effect sizes that were comparable between studies. Improvements in functional outcome are consistently greater than those observed in patients treated with haloperidol and similar in magnitude to those seen with three other atypical antipsychotics, namely olanzapine, ziprasidone and risperidone. A patient-reported outcome measure was used in only one comparative study, and demonstrated perception of a

    In order to deal with the explosive growth of mobile data traffic, a novel design of network architecture will be adopted in 5G. Software Defined Network (SDN) and Network Function Virtualization (NFV) are the key technologies for network transformation, which will drive the innovation of mobile communication network architecture. The deployment of Virtualized Network Function (VNF) in service chain is a critical issue in network virtualization. To overcome the ignorance of VNF sequence constraints in service chain and the characteristics of mobile business in existing literatures, an adaptive deployment method of VNF based on Viterbi algorithm is proposed. With real-time perception of the resources change of underlying nodes, the topology structure will be adjusted dynamically. Hidden Markov model is used to describe the topology information of available nodes with resources constraints in underlying network, and the service path with shortest delay is selected based on Viterbi algorithm in candidate service node. Experimental results show that the process time of service chain can be lower compared with existing algorithm. In addition, the acceptance rates of service chain requests and cost efficiency of underlying resources are also raised.%为了应对移动数据流量的爆炸性增长,5G移动通信网将引入新型的架构设计.软件定义网络和网络功能虚拟化是网络转型的关键技术,将驱动移动通信网络架构的创新,服务链虚拟网络功能的部署是网络虚拟化研究中亟待解决的问题.该文针对已有部署方法未考虑服务链中虚拟网络功能间顺序约束和移动业务特点的问题,提出一种基于Viterbi算法的虚拟网络功能自适应部署方法.该方法实时感知底层节点的资源变化并动态调整拓扑结构,采用隐马尔科夫模型描述满足资源约束的可用的底层网络节点拓扑信息,基于Viterbi算法在候选节点中选择时延最短的服务路径.

    Deployment of folded paper architecture using a fluid medium as the morphing stimulus presents a simple and inexpensive methodology capable of self-actuation; where the underlying principles can be translated to develop smart fibrous materials capable of programmable actuations. In this study we characterise different paper architectures and their stimuli mechanisms for folded deployment; including the influence of porosity, moisture, surfactant concentration, temperature, and hornification. We observe that actuation time decreases with paper grammage; through the addition of surfactants, and when the temperature is increased at the fluid-vapour interface. There is a clear effect of hydration, water transport and the interaction of hydrogen bonds within the fibrous architecture which drives the deployment of the folded regions. The importance of fibre volume fraction and functional fillers in shape recovery was also observed, as well as the effect of a multilayer composite paper system. The design guidelines shown here will inform the development of synthetic fibrous actuators for repeated deployment.

    This study examined body image in adult women along with probable correlates including health behaviors, negative affect, quality of life, and functional impairment. Adult women ( N = 738, age = 25-86 years) completed an online survey assessing these domains. Women across all ages reported similar body image concerns. Negative body image significantly correlated with poorer wellness behaviors, negative affect, quality of life, and functional impairment. The inverse held for positive body image. The majority of correlations remained even when controlling for negative affect. Further research is warranted to investigate nature of the correlational relationships identified in this study.

To compare the quality of life and functional health of long-term meditators to that of the normative population in Australia. Method. Using the SF-36 questionnaire and a Meditation Lifestyle Survey, we sampled 343 long-term Australian Sahaja Yoga meditation practitioners and compared their scores to those of the normative Australian population. Results. Six SF-36 subscales (bodily pain, general health, mental health, role limitation-emotional, social functioning, and vitality) were significantly better in meditators compared to the national norms whereas two of the subscales (role limitation-physical, physical functioning) were not significantly different. A substantial correlation between frequency of mental silence experience and the vitality, general health, and especially mental health subscales (P definition of meditation in enhancing quality of life, functional health and wellbeing is growing. Implications for primary mental health prevention are discussed.

    In this work, a general protocol for evaluating the quality of approximate Kubo correlation functions of nontrivial systems in many dimensions is discussed. We first note that the generalized deconvolution of the Kubo transformed correlation function onto a time correlation function at a given value τ in imaginary time, such that 0 function and whose iterative extension allows us to link derivatives of different order in the corresponding correlation functions. We focus on the case when τ = βℏ/2, for which all deconvolution kernels become real valued functions and their asymptotic behavior at long times exhibits a polynomial divergence. It is then shown that thermally symmetrized static averages, and the averages of the corresponding time derivatives, are ideally suited to investigate the quality of approximate Kubo correlation functions at successively larger (and up to arbitrarily long) times. This overall strategy is illustrated analytically for a harmonic system and numerically for a multidimensional double-well potential and a Lennard-Jones fluid. The analysis includes an assessment of RPMD position autocorrelation results as a function of the number of dimensions in a double-well potential and of the RPMD velocity autocorrelation function of liquid neon at 30 K.

    This study assessed differences between men and women in the association of perceptions of service quality with customer evaluations. Functional (efficiency with which the service is delivered) and relational (customers' emotional benefits, beyond the core performance, related to the social interaction of customers with employees) dimensions of service quality were measured as well as customer satisfaction and loyalty. The sample of 277 customers (191 men, 86 women), surveyed in 29 Mexican hotels, had a mean age of 38.1 yr. (SD=9.7) for men and 34.5 yr. (SD=11.0) for women. To be eligible for survey, customers had to have spent at least one night in the hotel in question. Analysis indicated that the women and men differed in the association of functional and relational dimensions of service quality with their satisfaction and loyalty. Functional service quality was higher for the men than the women, while relational service quality showed greater predictive power for women than for men, although these accounted for only 4% of the customers' satisfaction variance and 6% of the loyalty variance.

    Sexual dysfunction is a common experience in women with fibromyalgia. However, the physiopathology of this association is unclear. We aimed to evaluate whether sleep disturbance has an influence on sexual function in women with fibromyalgia. Fifty-four sexually active premenopausal women with fibromyalgia were enrolled in the study. The following questionnaires were used: the Female Sexual Function Index (FSFI), the Pittsburgh Sleep Quality Index (PSQI), the Fibromyalgia Impact Questionnaire (FIQ) and the Beck Depression Inventory (BDI). Appropriate statistical analyses were used by using SPSS 18. The mean FSFI score was 25.344 ± 6.52 and showed no correlation with age, body mass index, BDI or duration of fibromyalgia. However, a positive correlation between sexual dysfunction and low sleep quality was found (r=0.43; P=0.001). In addition, the median FSFI score was 29.2 (27.2-32.4) in patients with higher sleep quality (PSQI⩽5), whereas it was 21.4 (18.9-25.3) in patients with lower sleep quality (PSQI>5) (Pfibromyalgia as indicated by a higher FIQ score (r=0.37; P=0.006). Sexual dysfunction in female patients with fibromyalgia may be due to low sleep quality. Treatment of the sleep disorder may improve female sexual function.

    The goal of this work is to create an integrated framework for forecasting the adoption of distributed energy resources (DER), both by electricity customers and by the various institutions within the industry itself, and for evaluating the effect of this adoption on the power system, particularly on the overall reliability and quality of electrical service to the end user. This effort and follow on contributions are intended to anticipate and explore possible patterns of DER deployment, thereby guiding technical work on microgrids towards the key technical problems. An early example of this process addressed is the question of possible DER adopting customer disconnection. A deployment scenario in which many customers disconnect from their distribution company (disco) entirely leads to a quite different set of technical problems than a scenario in which customers self generate a significant share or all of their on-site electricity requirements and additionally buy and sell energy and ancillary services (AS) locally and/or into wider markets. The exploratory work in this study suggests that the economics under which customers disconnect entirely are unlikely.

    The Regional Energy Deployment System (ReEDS) is a deterministic optimization model of the deployment of electric power generation technologies and transmission infrastructure throughout the contiguous United States into the future. The model, developed by the National Renewable Energy Laboratory's Strategic Energy Analysis Center, is designed to analyze the critical energy issues in the electric sector, especially with respect to potential energy policies, such as clean energy and renewable energy standards or carbon restrictions. ReEDS provides a detailed treatment of electricity-generating and electrical storage technologies and specifically addresses a variety of issues related to renewable energy technologies, including accessibility and cost of transmission, regional quality of renewable resources, seasonal and diurnal generation profiles, variability of wind and solar power, and the influence of variability on the reliability of the electrical grid. ReEDS addresses these issues through a highly discretized regional structure, explicit statistical treatment of the variability in wind and solar output over time, and consideration of ancillary services' requirements and costs.

    Introduction Rapid deployment valves (RDV) represent a newly introduced approach to aortic valve replacement which facilitates surgical implantation and minimally invasive techniques, shortens surgical times and shows excellent haemodynamic performance. However, evidence on their safety, efficacy and potential complications is mostly fitted with small-volume and retrospective studies. Moreover, no current guidelines exist. To improve our knowledge on this technology, The Rapid Deployment Aortic Replacement (RADAR) Registry will be established across Spain with the aim of assessing RDV outcomes in the real-world setting. Methods and analysis The RADAR Registry is designed as a product registry that would provide information on its use and outcomes in clinical practice. This multicentre, prospective, national effort will initially involve 4 centres in Spain. Any patient undergoing cardiac surgery for aortic valve replacement and receiving an RDV as an isolated operation or in combination with other cardiac procedures may be included. Participation is voluntary. Data collection is equal to information obtained during standard care and is prospectively entered by the participating physicians perioperatively and during subsequent follow-up visits. The primary outcome assessed is in-hospital and up to 5 years of follow-up, prosthetic valve functioning and clinical status. Secondary outcomes are to perform subgroup analysis, to compare outcomes with other existing approaches and to develop future clinical guidelines. The follow-up assessments are timed with routine clinical appointments. Dissociated data will be extracted and collectively analysed. Initial target sample size for the registry is 500 participants entered with complete follow-up information. Different substudies will be implemented within the registry to investigate specific populations undergoing aortic valve replacement. Ethics and dissemination The protocol is approved by all local institutional ethics

    Full Text Available Abstract Background While there are many published studies on HIV and functional limitations, there are few in the context of early abuse and its impact on functionality and Quality of Life (QoL in HIV. Methods The present study focused on HIV in the context of childhood trauma and its impact on functionality and Quality of Life (QoL by evaluating 85 HIV-positive (48 with childhood trauma and 37 without and 52 HIV-negative (21 with childhood trauma and 31 without South African women infected with Clade C HIV. QoL was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q, the Patient's Assessment of Own Functioning Inventory (PAOFI, the Activities of Daily Living (ADL scale and the Sheehan Disability Scale (SDS. Furthermore, participants were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D and the Childhood Trauma Questionnaire (CTQ. Results Subjects had a mean age of 30.1 years. After controlling for age, level of education and CES-D scores, analysis of covariance (ANCOVA demonstrated significant individual effects of HIV status and childhood trauma on self-reported QoL. No significant interactional effects were evident. Functional limitation was, however, negatively correlated with CD4 lymphocyte count. Conclusions In assessing QoL in HIV-infected women, we were able to demonstrate the impact of childhood trauma on functional limitations in HIV.

    Volunteers' motives have been differentially linked to various aspects of successful volunteering. Using self-determination theory, we propose that volunteer functions are systematically related to the experience of self-determined versus controlled motivation. This "quality of motivation," in turn, explains why motives are differentially associated with satisfaction. We conducted two studies: Study 1 (N1 = 824) addressed motives, quality of motivation, and satisfaction; Study 2 (N2 = 323) additionally examined function-specific benefits and the extent to which they match volunteers' motives. Overall, our hypotheses were supported: values, understanding, and social justice motives were positively associated with relatively self-determined motivation (RSM), whereas career, social, protective, and enhancement motives showed negative correlations. The relationships between motives and satisfaction were partially mediated by RSM. Concerning benefits, Study 2 corroborated these findings for values, protective, enhancement, and social justice. This research introduces a new perspective on the quality of volunteers' motives-with theoretical and practical implications.

    Full Text Available Recent research regarding the quality of life developed different approaches concerning the use of objective and subjective indicators, as well as the relevance of hypotheses, propositions and methods of analysis or of evaluation. Starting from the conceptual difficulties regarding the term of ‘quality of life’, this article focuses upon the contributions of Amartya Sen on the relationships between resources, liberties, capabilities, functionalities and human development. A separate section attempts to capture the shift of accent from the approaches of a quantitative type towards those of a qualitative type, founded on capabilities, functionalities, and the factors of conversion of resources into elements of quality of subjective life. The following sections are consecrated to the contributions to the development of the model proposed by Amartya Sen and to the reception of this model by a few specialists in the field, as well as to its relevance within scientific research and the foundation of public policies.

    2007-09-01

    Full Text Available Background: Functional dyspepsia (FD is a heterogeneous disorder of yet unknown etiology which causes a significant reduction in the quality of life. In this study, we compared the effect of buspirone as an agonist of serotonin 5HT1A receptor with amitriptyline and placebo on improving the symptoms and quality of life in patients with functional dyspepsia. Methods: This study was a double-blinded, randomized controlled clinical trial. Using a sequential sampling, patients with the diagnostic criteria of Rome 2 and normal gastrointestinal findings were selected. The subjects were randomly divided into three therapeutic groups receiving amitriptyline, buspirone, and placebo. We used Nepean Dyspepsia Inde (NDI to evaluate the quality of life before and after the treatment. Results: The mean age of subjects was 35.38±12.94 years. Symptom and quality of life scores of the three groups were equal at the beginning but at the end of treatment, these scores were different. Buspirone was more effective than both amitriptyline and placebo in reducing the symptom of early satiety. Buspirone showed a better improvement in quality of life compared to placebo. Both Buspirone and amitriptyline were more effective than placebo in decreasing the symptom of epigastric pain. Conclusion: Our study confirmed the positive effect of buspirone on the quality of life and symptoms (like early satiety and abdominal pain in patients with functional dyspepsia. Since the mechanism of action of buspirone and also the pathophysiology of functional dyspepsia are still unknown, further studies are necessary to clarify every aspect of the disease and therapeutic effects of various treatments on it.

    [Purpose] To compare function, activity, participation, and quality of life of Down syndrome children and typically developing children according to age. [Subjects and Methods] A total of 16 Down syndrome children and 20 children with typical development were included as subjects for this study. International Classification of Functioning, Disability, and Health (ICF) Child and Youth version (CY) developed by the World Health Organization (WHO) and a questionnaire were used to measure children's functioning, activity, and participation. To measure quality of life, KIDSCREEN 52-HRQOL questionnaire was used in this study. [Results] ICF-CY function, activity, participation, and quality of life showed statistically significant differences between Down syndrome children and typically developing children. Down syndrome children with higher functions showed higher activities and participation. Higher function, activity and participation features were correlated with better quality of life. Higher function resulted in better quality of life. [Conclusion] Function, activity, participation, quality of life, and several common factors of Down syndrome children depend on the ability of children. Function of Down syndrome children affects their activity, participation, and quality of life. Activities and participations also affect quality of life. Therefore, children's functional aspect is the foundation for quality of life.

    Infants who require extracorporeal membrane oxygenation (ECMO) support after a Norwood operation are at increased risk for early and late death compared with patients who do not require ECMO post-Norwood. Little is known about the effect that ECMO post-Norwood has on functional status and quality of life among long-term survivors. We prospectively evaluated functional status and health-related quality of life in 12 surviving patients (cases) and 19 corresponding patients (controls) from a previous retrospective case-control assessment of long-term survival in patients requiring ECMO post-Norwood. Functional status was assessed with the Vineland Adaptive Behavior Scale-II, and health-related quality of life was assessed with the Pediatric Quality of Life Inventory (PedsQL) core and cardiac modules. There were no differences in demographics, extracardiac or genetic anomalies, or age at follow-up assessment between ECMO cases and non-ECMO controls. The Vineland Adaptive Behavior Scale-II scores were comparable between groups, with both groups demonstrating function in the normal range in all four domains tested. The only difference in PedsQL scores between cases and controls was perceived physical appearance, which was lower among ECMO survivors by both patient and proxy report. PedsQL scores of both groups were comparable to published scores for patients with single-ventricle congenital heart disease but generally lower than scores for the healthy population. The requirement for ECMO support after a Norwood operation does not appear to significantly affect functional status or quality of life among the subset of patients who achieve long-term survival.

    Full Text Available BACKGROUND: Breast cancer is the most common malignancy in Brazilian women. In recent years, there has been great progress in and an increasing number of breast-conserving surgical techniques; however, immediate or late morbidity after surgery, in the form of functional impairment and pain, remains a significant clinical problem. OBJECTIVE: To investigate the relationship between late upper limb functional impairment and the quality of life in women subjected to breast cancer surgery. METHOD: A total of 81 women participated in the study, with the length of time since surgery ranging from one to five years. A survey of upper limb complaints reported by patients was conducted, and the questionnaires Disabilities of the Arm, Shoulder, and Hand (DASH and the European Organization for Research and Treatment of Cancer (EORTC QLQC-30 and BR23 were applied. RESULTS: The correlation between the DASH score and the length of time since surgery determined that the longer the time since surgery, the greater the difficulties in functionality of the upper limb (r=0.459; p<0.0001. A statistically significant correlation was observed between the DASH score and health-related quality of life. CONCLUSION: Late functional impairment had a significant impact on upper limb function in everyday life and health-related quality of life for women who underwent breast cancer surgery.

    Full Text Available As the use of camera networks has expanded, camera placement to satisfy some quality assurance parameters (such as a good coverage ratio, an acceptable resolution constraints, an acceptable cost as low as possible, etc. has become an important problem. The discrete camera deployment problem is NP-hard and many heuristic methods have been proposed to solve it, most of which make very simple assumptions. In this paper, we propose a probability inspired binary Particle Swarm Optimization (PI-BPSO algorithm to solve a homogeneous camera network placement problem. We model the problem under some more realistic assumptions: (1 deploy the cameras in the 3D space while the surveillance area is restricted to a 2D ground plane; (2 deploy the minimal number of cameras to get a maximum visual coverage under more constraints, such as field of view (FOV of the cameras and the minimum resolution constraints. We can simultaneously optimize the number and the configuration of the cameras through the introduction of a regulation item in the cost function. The simulation results showed the effectiveness of the proposed PI-BPSO algorithm.

    Previous studies have shown that deficits in social cognition mediate the association between neuro-cognition and functional outcome. Based on these findings, the current study presents an examination of the mediating role of social cognition and includes two different outcomes: social functioning assessed by objective observer and social quality of life assessed by subjective self-report. Instruments measuring different aspects of social cognition, cognitive ability, social functioning and social quality of life were administered to 131 participants who had a diagnosis of a serious mental illness. Results showed that emotion recognition and attributional bias were significant mediators such that cognitive assessment was positively related to both, which in turn, were negatively related to SQoL. While one interpretation of the data suggests that deficits in emotion recognition may serve as a possible defense mechanism, future studies should re-assess this idea. Copyright © 2017 Elsevier B.V.

    To evaluate the effect of the kinesiotherapy in the quality of life, sexual function and menopause-related symptoms and compare in climacteric women with and without fibromyalgia (FM). the group was composed of 90 climacteric women divided in 2 groups: FM (47) and control (43). The patients were analyzed on their quality of life (Utian Quality of Life [UQoL]), sexual function (Sexual Quotient-Female Version [SQ-F] questionnaire) and intensity of the climacteric symptoms (Blatt-Kupperman menopausal index [BKMI]). Both groups performed pelvic floor kinesiotherapy, composed of 20 sessions, twice a week. Statistical analysis was performed using Student's t-test, mixed-design analysis of variance (ANOVA) and Cohen's Kappa. In the quality of life, an improvement was noticed in both groups for all domains analyzed. In the comparison between groups it was noticed a difference in the emotional (p=0.01), health (p=0.03) and sexual (p=0.001) domains with considerable gains verified in the control group. Improvement was also noticed in the sexual function. In the analysis between groups, FM group showed a lower score compared to the control group (p < 0.001). With respect to the climacteric symptoms, there was no difference in the analysis between groups after the intervention (p < 0.001). The pelvic floor kinesiotherapy promotes a positive effect in the domains of quality of life, sexual function and climacteric symptoms in women with and without fibromyalgia in the climacteric period; however, fibromyalgia seems to be a limiting factor to achieve better results in some of the aspects evaluated.

    Full Text Available Background Methadone maintenance has remained the main modality of treatment for opioid dependent subjects. Side effects of methadone treatment may be potential obstacles to its continuation. Sleep quality and sexual function are two culture-based concerns, directly related to patients’ compliance with methadone maintenance treatment (MMT program. Objectives This research was conducted to examine the frequency of sleep disparity and sexual dysfunction in patients under MMT referring to MMT clinics of Kerman, Iran. Patients and Methods In this cross-sectional study, 198 adult subjects under MMT for more than 6 months were enrolled. Measurement tool consisted of Pittsburgh sleep quality index (PSQI, Arizona sexual experience scale (ASEX, the 12-item general health questionnaire (GHQ-12, and a demographic questionnaire. The questionnaires were self-completed, except where individuals were illiterate. Results Mean ± SD age of the subjects was 41.2 ± 7.9 years and 93.4% of them were male. More than half of them used heroin. Prevalence of poor sleeping and sexual dysfunction in patients under MMT were 67.7% and 18.2%, respectively. There was no association between sleep quality or sexual dysfunction and demographics or methadone dose. However, a significant correlation was observed between mental health and sleep quality (r =0.16, P = 0.033, and sexual function (r = 0.18, P = 0.011. Conclusions Sleep quality showed a poorer profile than sexual function. Therefore, more emphasis should be laid on treatment of sleep disparity during follow up of MMT patients comparing to their sexual function. Patients should be reassured that probable sexual dysfunctions should not be regarded as a consequence of MMT.

    Full Text Available Abstract Background Cognition is a multidimensional construct and to our knowledge, no previous studies have examined the independent contribution of specific domains of cognition to health related quality of life. To determine whether executive functions are independently associated with health related quality of life assessed using Quality Adjusted Life Years (QALYs calculated from the EuroQol EQ-5D (EQ-5D in older women after adjusting for known covariates, including global cognition. Therefore, we conducted a secondary analysis of community-dwelling older women aged 65-75 years who participated in a 12-month randomized controlled trial of resistance training. We assessed global cognition using the Mini-Mental State Examination (MMSE and executive functions using the: 1 Stroop Test; 2 Trail Making Test (Part B and 3 Digits Verbal Span Backwards Test. We calculated QALYs from the EQ-5D administered at baseline, 6 months and 12 months. Results Our multivariate linear regression model demonstrated the specific executive processes of set shifting and working memory, as measured by Trail Making Test (Part B and Digits Verbal Span Backward Test (p Conclusions Our study highlights the specific executive processes of set shifting and working memory were independently associated with QALYs -- a measure of health related quality of life. Given that executive functions explain variability in QALYs, clinicians may need to consider assessing executive functions when measuring health related quality of life. Further, the EQ-5D may be used to track changes in health status over time and serve as a screening tool for clinicians. Trial Registration ClinicalTrials.gov Identifier: NCT00426881.

  1. Energy-Efficient Heterogeneous Wireless Sensor Deployment with Multiple Objectives for Structural Health Monitoring.

    2016-11-06

    Heterogeneous wireless sensor networks (HWSNs) are widely adopted in structural health monitoring systems due to their potential for implementing sophisticated algorithms by integrating a diverse set of devices and improving a network's sensing performance. However, deploying such a HWSN is still in a challenge due to the heterogeneous nature of the data and the energy constraints of the network. To respond to these challenges, an optimal deployment framework in terms of both modal information quality and energy consumption is proposed in this study. This framework generates a multi-objective function aimed at maximizing the quality of the modal information identified from heterogeneous data while minimizing the consumption of energy within the network at the same time. Particle swarm optimization algorithm is then implemented to seek solutions to the function effectively. After laying out the proposed sensor-optimization framework, a methodology is present to determine the clustering of the sensors to further conserve energy. Finally, a numerical verification is performed on a four-span pre-stressed reinforced concrete box-girder bridge. Results show that a set of strategically positioned heterogeneous sensors can maintain a balanced trade-off between the modal information accuracy and energy consumption. It is also observed that an appropriate cluster-tree network topology can further achieve energy saving in HWSNs.

  2. Stochastic Optimization for Nuclear Facility Deployment Scenarios

    Hays, Ross Daniel

    Single-use, low-enriched uranium oxide fuel, consumed through several cycles in a light-water reactor (LWR) before being disposed, has become the dominant source of commercial-scale nuclear electric generation in the United States and throughout the world. However, it is not without its drawbacks and is not the only potential nuclear fuel cycle available. Numerous alternative fuel cycles have been proposed at various times which, through the use of different reactor and recycling technologies, offer to counteract many of the perceived shortcomings with regards to waste management, resource utilization, and proliferation resistance. However, due to the varying maturity levels of these technologies, the complicated material flow feedback interactions their use would require, and the large capital investments in the current technology, one should not deploy these advanced designs without first investigating the potential costs and benefits of so doing. As the interactions among these systems can be complicated, and the ways in which they may be deployed are many, the application of automated numerical optimization to the simulation of the fuel cycle could potentially be of great benefit to researchers and interested policy planners. To investigate the potential of these methods, a computational program has been developed that applies a parallel, multi-objective simulated annealing algorithm to a computational optimization problem defined by a library of relevant objective functions applied to the Ver ifiable Fuel Cycle Simulati on Model (VISION, developed at the Idaho National Laboratory). The VISION model, when given a specified fuel cycle deployment scenario, computes the numbers and types of, and construction, operation, and utilization schedules for, the nuclear facilities required to meet a predetermined electric power demand function. Additionally, it calculates the location and composition of the nuclear fuels within the fuel cycle, from initial mining through

    More Reserve and Guard members have been activated in the past few years than in any other time in history. In addition to the high rates of psychological and behavioral challenges among military personnel, there are other equally important post-deployment reintegration challenges. Post-deployment reintegration challenges are particularly important to Reserve and Guard members, who transition rapidly from civilian-military-civilian. This study aims to describe the scope of challenges that a battalion of National Guard members (NGM) report experiencing after returning from a one-year deployment to Iraq. This article reports data from a sample of 126 NGM who recently returned from a one-year deployment to Iraq. The scope of post-deployment problems at baseline, 3- and 6-month post-deployment are presented. Overall, the rates of post-deployment psychological and behavioral problems were elevated upon returning from deployment and remained fairly constant for up to 6 months post-deployment. Approximately 30% of respondents were unsatisfied with their relationship and upwards of 30% reported family reintegration challenges. Comparisons with similar research and implications for prevention and improvement of post-deployment quality of life are addressed.

  4. Ethnic differential item functioning in the assessment of quality of life in cancer patients

    2005-10-01

    Full Text Available Abstract Background Past research has shown that Filipino cancer patients report lower levels of quality of life (QoL than other ethnic groups. One possible explanation for this is that Filipinos do not define QoL in the same manner as others, resulting in bias in their assessments. Hence, Filipinos would not necessarily have lower QoL. Methods Item response theory methods were used to assess differential item functioning (DIF in the quality of life (measured by the EORTC QLQ-C30 of cancer patients across four ethnic groups (Caucasian, Filipino, Hawaiian, and Japanese. The sample consisted of 359 cancer patients. Results Results showed the presence of DIF on several items, indicating ethnic differences in the assessment of quality of life. Relative to the Caucasian and Japanese groups, items related to physical functioning, cognitive functioning, social functioning, nausea and vomiting, and financial difficulties exhibited DIF for Filipinos. On these items Filipinos exhibited either higher or lower QoL scores, even though their overall QoL was the same. Conclusion This evidence may explain why Filipinos have previously been found to have lower overall QoL. Although Filipinos score lower on QoL than other groups, this may not reflect lower QoL, but rather differences in how QoL is defined. The presence of DIF did not appear, however, to alter the psychometric properties of the QLQ-C30.

    To describe the cognitive functions, mood, and quality of life in a family with genetically proved familial hemiplegic migraine (FHM), carrying a missense mutation on chromosome 19 (T666M), corresponding to the most frequent FHM subtype. FHM is an autosomal dominant subtype of migraine with an aura, characterized by hemiparesis during the aura. Whereas the genetic background of FHM has been studied intensely, less attention has been paid to cognitive functions and mood between attacks. Six patients performed neuropsychologic assessment between attacks. Depression, anxiety, and quality of life were evaluated by questionnaires. Cerebral magnetic resonance imaging was performed. Neuropsychologic assessment revealed a distinct pattern of preserved and impaired functions. Whereas linguistic abilities and verbal memory were intact, all patients showed deficits in figural memory, executive functions, in some aspects of attention, and in dexterity. Intelligence of 1 patient was below average. All but 1 patient reported normal quality of life; there were no symptoms of depression or state anxiety. All patients showed cerebellar atrophy and cerebellar ataxia. Cognitive abnormalities and cerebellar atrophy were found in all patients. FHM-related cognitive deficits may be associated to a disturbance of cerebrocerebellar circuits.

    The RSG deployment case design is centered on taking the RSG system and producing a transport case that houses the RSG in a safe and controlled manner for transport. The transport case was driven by two conflicting constraints, first that the case be as light as possible, and second that it meet a stringent list of Military Specified requirements. The design team worked to extract every bit of weight from the design while striving to meet the rigorous Mil-Spec constraints. In the end compromises were made primarily on the specification side to control the overall weight of the transport case. This report outlines the case testing results.

    Full Text Available Background. There is very little data describing the long-term health impacts of meditation. Aim. To compare the quality of life and functional health of long-term meditators to that of the normative population in Australia. Method. Using the SF-36 questionnaire and a Meditation Lifestyle Survey, we sampled 343 long-term Australian Sahaja Yoga meditation practitioners and compared their scores to those of the normative Australian population. Results. Six SF-36 subscales (bodily pain, general health, mental health, role limitation—emotional, social functioning, and vitality were significantly better in meditators compared to the national norms whereas two of the subscales (role limitation—physical, physical functioning were not significantly different. A substantial correlation between frequency of mental silence experience and the vitality, general health, and especially mental health subscales (P<0.005 was found. Conclusion. Long-term practitioners of Sahaja yoga meditation experience better functional health, especially mental health, compared to the general population. A relationship between functional health, especially mental health, and the frequency of meditative experience (mental silence exists that may be causal. Evidence for the potential role of this definition of meditation in enhancing quality of life, functional health and wellbeing is growing. Implications for primary mental health prevention are discussed.

    Deployable subsystems are essential to mission success of most spacecraft. These subsystems enable critical functions including power, communications and thermal control. The loss of any of these functions will generally result in loss of the mission. These subsystems and their components often consist of unique designs and applications, for which various standardized data sources are not applicable for estimating reliability and for assessing risks. In this study, a Bayesian approach for reliability estimation of spacecraft deployment was developed for this purpose. This approach was then applied to the James Webb Space Telescope (JWST) Sunshield subsystem, a unique design intended for thermal control of the observatory's telescope and science instruments. In order to collect the prior information on deployable systems, detailed studies of "heritage information", were conducted extending over 45 years of spacecraft launches. The NASA Goddard Space Flight Center (GSFC) Spacecraft Operational Anomaly and Reporting System (SOARS) data were then used to estimate the parameters of the conjugative beta prior distribution for anomaly and failure occurrence, as the most consistent set of available data and that could be matched to launch histories. This allows for an emperical Bayesian prediction for the risk of an anomaly occurrence of the complex Sunshield deployment, with credibility limits, using prior deployment data and test information.

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

    The aim of this study is to evaluate the effects of replacing poorly fitting dentures on patient's masticatory function, satisfaction and oral health-related quality of life. Fourteen patients with conventional maxillary complete dentures and mandibular overdentures retained by two implants bar clip system had their dentures replaced. The laboratory tests for the analysis of masticatory performance were conducted using an "Optocal" food simulator test. Questionnaires were used to evaluate patient satisfaction with dentures and impact of oral health on quality of life. Tests were conducted and questionnaires were administered before and 1, 3 and 6 months after the patient had adapted to the new dentures. Masticatory performance data and satisfaction with dentures (Visual Analogic Scale) were statistically analyzed by ANOVA and Tukey b test, satisfaction with dentures (SATs P) and impact of oral health on quality of life were evaluated using the Wilcoxon and Friedman tests (a=.05). There was no statistically significant improvement in masticatory function after denture replacement, although better outcomes were observed. Satisfaction with dentures and total score obtained using the OHIPedent showed significant improvement. It can be suggested that the potential for grinding food, patient satisfaction and aspects of quality of life improved immediately after denture replacement.

    2010-01-01

    Full Text Available This research project used Functional Measurement to examine how the brand name of consumer products impacts intended purchasing decisions. Thirty undergraduate students tested actual products from three different product categories (crayons, tissues, and tortilla chips. Each product category consisted of three different brands; one with high brand value, one with medium, and one with low brand (generic value. For each brand, there were five conditions: 1 the product with the correct brand name; 2 the product with a switched brand name; 3 the product with another switched brand name; 4 the product alone with no brand name; and 5 the brand name alone with no product. Participants were unaware that products had been switched. After trying each product, participants rated their likelihood to purchase on a 9-point Likert scale: 1 being "definitely would not buy" and 9 being "definitely would buy." Results revealed that perceptions of quality were dependent on both perceived product quality and brand name. Unexpectedly, results also showed that the strength of the brand equity effect is dependent on product type, e.g., chips showed the strongest brand effect. For most product categories, main effects and interactions were significant. Functional measurement analyses revealed that brand name effects were independent of product quality. In conclusion, the brand name associated with a product led people to evaluate quality of that product as either higher or lower depending on the strength of the brand name.

    This paper will consider how Quality Function Deployment (QFD) and Design for Manufacture and Assembly (DFMA) processes can be used to improve the design quality of products at the concept stage. We appreciate that both QFD and DFMA are techniques that have been used for some time by mature product...... quality is maintained in design project work. The projects described have been carried out with products manufactured by small to medium sized enterprises (SME's), where we have found significant opportunities for product improvement. The quantitative nature of DFMA analysis results allows the novice...... for continuous improvement of their products. However, we consider that if novice designers are able to successfully utilise design tools like QFD and DFMA and achieve improvements in design quality, then SME’s have no excuses for ignoring the benefits they could bring to their own product development activity....

    This study examined heterogeneity in response patterns of the participants of the Survey of Activities and Fear of Falling in the Elderly (SAFFE) and their relationships to falls, functional ability, quality of life, and activity restriction measures in a cohort of 256 older people (mean age = 77.5 years). Participants recruited from local primary care clinics were administered the SAFFE instrument, an activity restriction measure, a combination of self-reported and performance-based functional ability tests, and quality-of-life measures. Latent class analyses identified two classes: Class 1 (n = 209), which had a low SAFFE fear of falling, and Class 2 (n = 47), which had a high SAFFE fear of falling. Subsequent analyses of variance indicated that the two-class (low fear and high fear) SAFFE fear of falling profiles discriminated fallers from nonfallers, and low and high levels of functional ability, activity restriction, and quality of life. The findings from this study suggest that variations in the SAFFE response patterns on a single dimension of fear of falling and that high levels of fear of falling measured by the SAFFE are linked to a range of adverse health consequences.

    Full Text Available This research aims to map out types of bilingual signboards found in Elementary and Secondary schools in Surakarta based on their functions, to assess their quality in terms of accuracy and acceptability, and to describe factors influencing the translation quality. This descriptive qualitative research used data sources in the form of documents and persons, i.e. bilingual signboards displayed on school walls and those called raters who have competencies in assessing translation quality. Content analysis, Interview, and Focus Group Discussion were applied as the methods to collect and analyze the data of bilingual signboards. As a result, there are three types of school signboard, namely signboards showing names of place, signboards showing the condition of a particular place, and those saying proverbs. Dealing with the function, signboards having informative, suggestive, restrictive and mandatory functions are identified. The majority of the data resulting accurate and less acceptable translation is found in universal signboards, while culture-bound signboards tend to be rendered less accurate and less acceptable due to some factors that can be read thoroughly in this article.

    The association between radiographic osteoarthritis (OA) and symptoms is inconsistent and variable according to each joint. The purpose of this study is to understand the relation between radiographic OA features, pain, function and quality of life, in knee and hip joints. A cross-sectional study was performed using information from EPIPorto cohort. Data was obtained by interview using a structured questionnaire on social, demographic, behavioural and clinical data. Pain was assessed using a pain frequency score (regarding ever having knee pain, pain in the last year, in the last 6 months and in the last month). Quality of life was evaluated with Short Form 36 (SF-36) and function disability with the Lequesne knee and hip indexes. Radiographic knees and hips were classified using the Kellgren-Lawrence score (KL 0-4). Linear regression and proportional odds ratios estimated the association between radiographic features, pain, function and quality of life. In our study, symptomatic OA (KL ≥ 2 plus joint pain) was 26.0 % in knee and 7.0 % hip joints. In knee, the increase on radiographic score increased the odds to have a higher pain frequency score [1.58 (95 % CI = 1.27, 1.97)] and was associated [adjusted β (95 % CI)] with worst general health [-3.05 (-5.00, -1.09)], physical function [-4.92 (-7.03, -2.80)], role-physical [-4.10 (-8.08, -0.11)], bodily pain [-2.96 (-5.45, -0.48)] and limitations in activities of daily living [0.48 (0.08, 0.89)]. Regarding hip, no significant associations were found between the severity of radiographic lesions and these measures. Radiographic lesions in knee were associated with higher complaints, as far as pain and functional limitations are concerned, compared with hip.

    Full Text Available Dyspepsia is a common disorder characterized by heartburn, nausea, vomiting, bloating, feelingof fullness or early satiety, and belching. Functional dyspepsia (FD or non-ulcer dyspepsia is asyndrome without any physical or endoscopic abnormalities underlying these symptoms. Theimpacts of FD on psychological disturbances and quality of life in patients have been postulated.However, it has not much been a concern. This study was conducted to evaluate the relationshipbetween symptoms of depression and quality of life in patients with FD. This was an observationalstudy with cross-sectional design involving 30 patients. The symptoms of depression weremeasured by beck depression inventory (BDI and the quality of life of patients were measuredby SF-36. The results showed that FD were more suffered consecutively by female patients(66.7%, age over 45 years (53.4%, housewives (56.6%, educated graduates (56.6% andmarried (90.0%. Moreover, patients who experienced symptoms of clinical depression withlow, moderate and severe levels were 16.3%, 33.3% dan 10.0%, respectively. A significantcorrelation between depressive symptoms and the overall of patients quality of life was observed(r = 0.481; p<0.05. Furthermore analysis showed that among eight domains of health in SF-36analyzed, a negative significant correlation was observed between the depressive symptoms andthe three domains of health i.e. general physical function, limitation of motion caused byphysical problems, and vitality. In conclusion, there is a negative correlation between depressivesymptoms and quality of life in patients with FD.

    To describe changes in joint motion, sensibility, and scar pliability and to investigate the patients' expectations, self-reported recovery, and satisfaction with hand function, disability, and quality of life after surgery and hand therapy for Dupuytren disease. This prospective cohort study collected measurements before surgery and 3, 6, and 12 months after surgery and hand therapy. Ninety patients with total active extension deficits of 60° or more from Dupuytren contracture were included. Outcomes measures were range of motion; sensibility; scar pliability; self-reported outcomes on expectations, recovery, and satisfaction with hand function; Disabilities of the Arm, Shoulder, and Hand scores; safety and social issues of hand function; physical activity habits; and quality of life with the Euroqol. The extension deficit decreased, and there was a transient decrease in active finger flexion during the first year after surgery. Sensibility remained unaffected. Generally, patients with surgery on multiple fingers had worse scar pliability. The majority of the patients had their expectations met, and at 6 months, 32% considered hand function as fully recovered, and 73% were satisfied with their hand function. Fear of hurting the hand and worry about not trusting the hand function were of greatest concern among safety and social issues. The Disability of the Arm, Shoulder, and Hand score and the Euroqol improved over time. After surgery and hand therapy, disability decreased independent of single or multiple operated fingers. The total active finger extension improved enough for the patients to reach a functional range of motion despite an impairment of active finger flexion still present 12 months after treatment.

    The quality of the healthy environment in a neighborhood city is decreasing in number. According to the government regulation, Act No. 26 of 2007, a city should have 20% of green areas from the total area of the city. Now, Semarang only has 7.5% of green areas from the total city area. One of the efforts made by the Government of Semarang is the establishment of a greenbelt in Jatibarang area. It consists of several parts, namely, the reservoirs in the green belt area and also the plant zone in other sectors. The reservoir has a function as the controller of water resources sustainability where the crops serve as the balance for the combination. Thus, it is interesting to study how the interplay of these two functions in a green belt area. The primary data used in this study was obtained from the locus of research by direct observation, interview, and physical data collection. Based on the data collection, data was then processed and analyzed in accordance with the indicators that had been compiled based on theories of reservoirs, green belts, and the quality of the urban environment. Government regulations regarding with the greenbelt and tanks were also used as references in the discussion. The research found out that the presence of the reservoir and the plants in the green belt of Jatibarang can improve the function of the green belt optimally which is a real influence for the improvement of the environment quality, especially water. The Greenbelt was divided into four zones, namely the Arboretum, Argo - Forestry, Ecotourism, Buffer - Zone also made the region became a beautiful greenbelt that brought a positive influence to environmental quality.

    Full Text Available Background: Stroke has a great impact not only on patients′ but also on their caregivers′ lives. Carers may experience high levels of burden that can result in deterioration of their health status, social life, and well-being. Association between quality of life (QOL of carers and that of stroke survivors in Indian setting is not much researched. Aims and Settings: To find out QOL and mental health of caregivers of individuals with stroke visiting Physiotherapy Department of Tertiary Care Center in Western India. Design and Methodology: A cross-sectional survey to find QOL and mental health of caregiver of stroke survivors, self-administered screening instrument WHO-QOL BREF, functional independence measurement (FIM scale, and BRIEF COPE were used for data collection on adult populations. Statistical Analysis Used: The statistical analysis was performed by descriptive analysis and correlation. Result: Fifty-four stroke patients and their caregivers (all adults were included in the study. Average FIM score was 83.75 (18.46 while median was 90 (25. FIM score of patients did not much affect QOL of caregivers. Discussion: Analysis of QOL data showed that QOL of caregivers was good in all domains, but patient′s QOL was good only in social relations. There was no correlation found in QOL of carers and stroke survivors. Nine percent of change in caregivers social relationship scores can be attributed to patients′ sphincter scores. Conclusion: QOL of carers and stroke survivors may be independent. Stroke patients in the study required a moderate assistance for their functional independence which does not seem to affect the caregivers QOL significantly.

    Quality improvement (QI) programs are frequently implemented to support primary healthcare (PHC) team development and to improve care outcomes. In Ontario, Canada, the Quality Improvement and Innovation Partnership (QIIP) offered a learning collaborative (LC) program to support the development of interdisciplinary team function and improve chronic disease management, disease prevention, and access to care. A qualitative study using a phenomenological approach was conducted as part of a mixed-method evaluation to explore the influence of the program on team functioning in participating PHC teams. A purposive sampling strategy was used to identify PHC teams (n = 10), from which participants of different professional roles were selected through a purposeful recruitment process to reflect maximum variation of team roles. Additionally, QI coaches working with the interview participants and the LC administrators were also interviewed. Data were collected through semistructured telephone interviews that were audiotaped and transcribed verbatim. Thematic analysis was conducted through an iterative and interpretive approach. The shared experience of participating in the program appeared to improve team functioning. Participants described increased trust and respect for each other's clinical and administrative roles and were inspired by learning about different approaches to interdisciplinary care. This appeared to enhance collegial relationships, collapse professional silos, improve communication, and increase interdisciplinary collaboration. Teamwork involves more than just physically grouping healthcare providers from multiple disciplines and mandating them to work together. The LC program provided opportunities for participants to learn how to work collaboratively, and participation in the LC program appeared to enhance team functioning.

    We compared three questionnaires that are used in the assessment of function and quality of life of patients with shoulder impingement syndrome. The study included 54 patients (42 females, 12 males; mean age 54 years) with a diagnosis of stage I or II shoulder impingement syndrome. All the patients were administered a standard questionnaire regarding their general health status (Short-Form 36 / SF-36). Functional evaluations were made using the UCLA (University of California at Los Angeles) and Constant scoring systems. The results of the UCLA and Constant scores were compared with those of SF-36 with the use of Pearson correlation analysis. A strong correlation was found between the UCLA and Constant scores (p=0.006). SF-36 parameters of physical function, vitality, and social function showed a strong correlation with the UCLA scores (p<0.005), whereas parameters of general health and role emotional exhibited a moderate correlation (p<0.05). When compared with the Constant scores, SF-36 showed a strong correlation only in parameters of pain and general health (p<0.005). The parameter of role emotional was negatively correlated with the Constant scores. Demonstration of correlations between some parameters of SF-36 and the UCLA and Constant scoring systems suggests that SF-36 can be used to assess quality of life of patients with shoulder impingement syndrome.

    Gossamer structures for innovative space applications, such as solar sails, require technology that allows their controlled and thereby safe deployment. Before employing such technology for a dedicated science mission, it is desirable, if not necessary, to demonstrate its reliability with a Technology Readiness Level (TRL) of six or higher. The aim of the work presented here is to provide reliable technology that enables the controlled deployment and verification of its functionality with various laboratory tests, thereby qualifying the hardware for a first demonstration in low Earth orbit (LEO). The development was made in the Gossamer-1 project of the German Aerospace Center (DLR). This paper provides an overview of the Gossamer-1 mission and hardware development. The system is designed based on the requirements of a technology demonstration mission. The design rests on a crossed boom configuration with triangular sail segments. Employing engineering models, all aspects of the deployment were tested under ambient environment. Several components were also subjected to environmental qualification testing. An innovative stowing and deployment strategy for a controlled deployment, as well as the designs of the bus system, mechanisms and electronics are described. The tests conducted provide insights into the deployment process and allow a mechanical characterization of that deployment process, in particular the measurement of the deployment forces. Deployment on system level could be successfully demonstrated to be robust and controllable. The deployment technology is on TRL four approaching level five, with a qualification model for environmental testing currently being built.

    Introduction Despite the economic importance of vineyards in Italy, the wine sector is facing severe challenges from increased global competition and climate changes. The quality of the grape at harvest has a strong direct impact on final wine quality and the strong relationship between wine composition, aroma, taste and soil properties has been outlined in the "Terroir concept". However, information on the impact of soil microbial communities on soil functions, grapevine plants and wine quality is still lacking. Objectives The aim of this study was to explore the composition and the potential functions of soil microbial communities associated to grapevine plants grown in two soils which showed similar physical, chemical and hydrological properties but which provided a different wine quality. Materials and Methods Soils from two sites of the Chianti region in Tuscany (BRO11 and BRO12) cultivated with the grapevine cultivar Sangiovese with contrasting wine quality were examined by means of a structural and functional approach: specifically, GeoChip microarrays, pyrosequencing of 16S rRNA and 18S rRNA genes, enzyme assays and measurements of some soil biological properties, such as microbial biomass C and soil respiration, were carried out. Results Enzyme assays and soil biological analyses revealed a higher biological activity in BRO11 as compared to BRO12. The structure of soil microbial communities, assessed using 16S and 18S rRNA gene-targeted pyrosequencing, revealed a higher presence of Actinobacteria in the BRO12 than in the BRO11 soil where, in contrast, the alfa-Proteobacteria are more abundant. GeoChip microarray analyses revealed a consistent difference in genes involved in S cycling, with a significant overrepresentation of sulfur-oxidation genes in BRO11 and increased levels of sulfate reduction genes BRO12. These results are consistent with the high content of sulfates and the abundance of Firmicutes such as Sulfobacillus thermosulfidooxidans in the BRO

    We estimated the prevalence of select mental health diagnoses (MHDX) and mental health treatment (MHT), and identified characteristics associated with MHT during the pre-deployment year (365 days before deployment) in active duty Army women (N = 14,633) who returned from Iraq or Afghanistan deployments in FY2010. Pre-deployment year prevalence estimates were: 26.2 % for any select MHDX and 18.1 % for any MHT. Army women who had physical injuries since FY2002 or any behavioral health treatment between FY2002 and the pre-deployment year had increased odds of pre-deployment year MHT. During the pre-deployment year, a substantial percentage of Army women had MHDX and at least one MHT encounter or stay. Future research should determine if pre-deployment MHDX among Army women reflect vulnerability to future MHDX, or if pre-deployment MHT results in protection from chronic symptoms.

    2013-12-01

    Full Text Available Nowadays, diabetes constitutes a significant medical, social and economic problem. According to the World Health Organization in 2025 the incidence of this disease will double in both developed and developing countries. Incidence of diabetes in Poland is 2–5% depending on the region. This disease leads to numerous restrictions in patient functioning. The need for continuous therapy and medical supervision as well as various complications exert a negative influence on the quality of life (QOL in this group of patients. One of those complications – the diabetic foot – is a particularly important problem. In many cases it leads to foot ulceration and, in consequence, amputation. These unfavorable aftermaths of diabetes not only cause limitations in physical functioning, but also negatively influence patients’ psychosocial functioning and require multidisciplinary support from a therapeutic care team.

    Wastewater stabilisation ponds (WSPs) are highly productive systems designed to treat wastewater using only natural biological and chemical processes. Phytoplankton, microbial communities and hydraulics play important roles for ecosystem functionality of these pond systems. Although WSPs have been used for many decades, they are still considered as 'black box' systems as very little is known about the fundamental ecological processes which occur within them. However, a better understanding of how these highly productive ecosystems function is particularly important for hydrological processes, as treated wastewater is commonly discharged into streams, rivers, and oceans, and subject to strict water quality guidelines. WSPs are known to operate at different levels of efficiency, and treatment efficiency of WSPs is dependent on physical (flow characteristics and sludge accumulation and distribution) and biological (microbial and phytoplankton communities) characteristics. Thus, it is important to gain a better understanding of the role and influence of pond hydraulics and vital microbial communities on pond performance and WSP functional stability. The main aim of this study is to investigate the processes leading to differences in treatment performance of WSPs. This study uses a novel and innovative approach to understand these factors by combining flow cytometry and metabolomics to investigate various biochemical characteristics, including the metabolite composition and microbial community within WSPs. The results of these analyses will then be combined with results from the characterisation of pond hydrodynamics and hydraulic performance, which will be performed using advanced hydrodynamic modelling and advanced sludge profiling technology. By understanding how hydrodynamic and biological processes influence each other and ecosystem function and stability in WSPs, we will be able to propose ways to improve the quality of the treatment using natural processes, with

    Full Text Available Objectives. Patients with vestibular schwannoma (VS frequently suffer from disabling vestibular symptoms. This prospective follow-up study evaluates vestibular and auditory function and impairment of quality of life due to vertigo, dizziness and imbalance in patients with unilateral vestibular schwannoma of different sizes before/ after microsurgical or radiosurgical treatment. Methods. 38 patients with unilateral vestibular schwannoma were included. 22 received microsurgery, 16 cyberknife radiosurgery. Two follow-ups took place after a median of 50 and 186.5 days. Patients received a standardized neuro-ophthalmological examination, electronystagmography with bithermal caloric testing, and pure-tone audiometry. Quality of life was evaluated with the Dizziness Handicap Inventory (DHI. Patient data was grouped and analyzed according to the size of the VS (group 1: < 20mm vs group 2: ≥ 20mm. Results. In group 1, the median loss of vestibular function was +10.5% as calculated by Jongkees Formula (range –43;+52; group 2: median + 36%, range –56; +90. The median change of DHI scores was –9 in group 1 (range –68;30 and +2 in group 2 (–54;+20. Median loss of hearing was 4dB (-42;93 in group 1 and 12dB in group 2 (5;42.Conclusions. Loss of vestibular function in vestibular schwannoma clearly correlates with tumor size. However, loss of vestibular function was not strictly associated with a long-term deterioration of quality of life. This may be due to central compensation of vestibular deficits in long-standing large tumors. Loss of hearing before treatment was significantly influenced by the age of the patient but not by tumor size. At follow-up 1 and 2, hearing was significantly worse in those patients with a large VS and after microsurgical treatment.

    Nutritional status of children with chronic kidney disease (CKD) is important since it affects growth and development. This study was to investigate overall diet quality measured by nutrient intake adequacy, nutrient density, and several dietary habits in children with CKD and its relationship with clinical parameters according to glomerular filtration rate (GFR). Assessment of nutritional status and diet quality was conducted in nineteen children with CKD. Average Z-scores of height, weight and body mass index (BMI) in the participants were less than standard growth rate. Nutritional status, such as Z-scores of height (p children with GFR children with GFR appetite and avoidance of food were observed in the children with higher blood urea nitrogen (BUN). Intakes of iron, zinc, thiamin, niacin, and vitamin B6 were positively correlated with GFR. Intakes of calcium, potassium and folate were positively correlated with BUN, while protein intakes were negatively correlated. Overall nutrient intakes were inadequate and diet quality was decreased as kidney function was decreased. Dietary habit and appetite were also related with kidney function in this study subjects. Systemic efforts of nutritional intervention are imperative to prevent deteriorating growth and development and improve the nutritional status in children with CKD.

    Chitosan is a natural polymer having diverse applications in food industry. The present study was undertaken to evaluate chitosan as a hydrocolloid in batter composition in developing enrobed fish sticks with better functional properties and improved quality. Different concentrations of chitosan gel were made in acetic acid medium and incorporated into batter for making enrobed fish sticks. Coating parameters, fat uptake, oil reduction, chemical quality parameters, instrumental texture analysis and colour were studied. Addition of chitosan gel had a significant effect (P<0.05) on the coating pickup, adhesion degree and cooking yield of the product. Total volatile basic nitrogen, pH, lipid oxidation parameters like peroxide value and thiobarbituric acid reactive substances of par-fried fish sticks also showed significant differences. The oil reduction in par-fried samples were 36.84, 65.05, 73.83, 77.65% respectively for 0.5, 1.0, 1.5, 2.0% chitosan added samples. Addition of chitosan significantly reduced crispness, gumminess, Warner-Bratzler shear force and toughness (P<0.05) of the product. The study clearly demonstrated that the inclusion of chitosan at 1.0% in batter can improve functional and other quality aspects of enrobed products. Copyright © 2017 Elsevier Ltd.

    The Child Health Questionnaire (CHQ), Pediatric Outcomes Data Collection Instrument (PODCI), and Pediatric Evaluation and Disability Inventory (PEDI) are the 3 instruments commonly used to measure function and quality of life in pediatric orthopaedics. This study compared answers to specific questions on the CHQ, PODCI, and PEDI given by the parents of 66 children with cerebral palsy, who completed all 3 questionnaires. Both Spanish- and English-speaking subjects were included. No overlapping questions were found between the CHQ and PEDI. Of the 8 questions that overlapped between the CHQ and PODCI, 2 questions (general health and change in health) had weighted kappa greater than 0.70, with responses within +/-1 point for more than 95% of respondents. These 2 questions had almost exactly the same wording on both questionnaires. The other 6 questions had fair to poor agreement between questionnaires (kappa, 0.10-0.55). All 5 questions that were addressed by both the PODCI and PEDI also had poor agreement (kappa < 0.40). There was little correspondence between the preconceived match quality and the actual matching results (r=0.41; P=0.16). These results suggest that differences in wording have a significant and unpredictable effect on parents' responses; this should be considered when selecting from among different instruments. Of the instruments used in this study, the CHQ is the easiest to administer and is a good general quality of life measure; however, the PODCI or PEDI may be preferred if information about more specific functional activities is desired.

    There is little in the literature comparing experiences of patients with disabling and uniformly terminal illness (e.g. amyotrophic lateral sclerosis) and illness characterized by episodic disability and prognostic uncertainty (e.g. multiple sclerosis). This study aimed to compare experiences of disability, quality of life (QoL) and psychological well-being in ALS and MS. One hundred patients with ALS and MS were interviewed at baseline and at six months. Variables measured included function, health related QoL, individualized QoL and psychological distress. Despite the divergent illness experiences of ALS and MS patients, groups did not differ on individualized QoL or mental well-being, and distress was in the normal range. Despite marked deterioration in ALS patients' health, there was no change in mental well-being and QoL. Psychological well-being appeared more important in maintaining QoL (individualized QoL and mental aspects of health related QoL) than physical factors. At the individual level, there was evidence of psychological adaptation to deteriorating function, which underlined the role of specific illness related challenges in determining perceived life quality and emotional well-being. In conclusion, the complex interplay between psychosocial and illness specific factors such as certainty with regard to prognosis has considerable implications for well-being and life quality. Recognizing such factors is essential when designing clinical interventions to promote adjustment and self-management among patients with neurological conditions.

    This study was envisaged to evaluate the effect of ground raw carrot (0%, 5%, 10% and 15%) and mashed sweet potato (0%, 5%, 10% and 15%) as functional ingredients on the quality of chicken meat nuggets. The products were evaluated for physicochemical quality, proximate composition, nutritive value, sensory quality as well as color and texture profile analyses. Additions of either raw carrot or mashed sweet potato represent an improvement in the nutritional value and have some beneficial effects due to the presence of dietary fibers and β-carotene. They were also found to be effective in sustaining the desired cooking yield and emulsion stability. Treated samples showed lower (p > 0.05) protein, fat and ash contents but higher (p < 0.05) moisture content than control. There were differences among the nugget samples with respect to sensory qualities, and control samples as well as samples with 10% added carrot/sweet potato had higher overall acceptability scores. Hunter color values (L*, a* and b* values) were higher (p < 0.05) for both the formulated products, while their textural parameters were nearly unchanged. In conclusion, carrot and sweet potato at 10% added level have greater potential as good source of dietary fibers and β-carotene and may find their way in meat industry.

    Design and test data for packaging, deploying, and assembling structures for near term space platform systems, were provided by testing light type hardware in the Neutral Buoyancy Simulator. An optimum or near optimum structural configuration for varying degrees of deployment utilizing different levels of EVA and RMS was achieved. The design of joints and connectors and their lock/release mechanisms were refined to improve performance and operational convenience. The incorporation of utilities into structural modules to determine their effects on packaging and deployment was evaluated. By simulation tests, data was obtained for stowage, deployment, and assembly of the final structural system design to determine construction timelines, and evaluate system functioning and techniques.

    Family function, which improves individual resilience and strongly link to quality of life (QOL) among the elderly, increases the risk of depression. Because of these demonstrated relationships, it can be hypothesized that both depression and resilience are mediators of the association between family function and QOL. To test this hypothesis, the structural equation model (SEM) constructed by Amos 21.0 was employed to assess the indirect effect of depression (Geriatric Depression Scale, GDS) and resilience (Connor-Davidson Resilience Scale, CD-RISC) on the relationship between family function (Family APGAR Score, APGAR) and QOL (12-item Short Form health survey, SF-12) in 474 elderly adults from three communities in Guangzhou, China. Correlation matrix showed that depression is significantly negatively correlated with family functioning (r=-0.54, Presilience (r=-0.46, Presilience is significantly positively correlated with family functioning (r=0.35, Presilience (β=0.089) and depression (β=0.307; combined β=0.056) on QOL (R(2)=0.55). The model fit indices showed a good fit of the model of the data (χ(2)/df=1.362, P>0.05, SRMR=0.023, RMSEA=0.028, GFI=0.985, NFI=0.987, TLI=0.993, CFI=0.996). The finding supports the assumption that depression and resilience are consistent intermediary factors of the relationship between family function and QOL among the elderly.

  9. A stowing and deployment strategy for large membrane space systems on the example of Gossamer-1

    Deployment systems for innovative space applications such as solar sails require a technique for a controlled and autonomous deployment in space. The deployment process has a strong impact on the mechanism and structural design and sizing. On the example of the design implemented in the Gossamer-1 project of the German Aerospace Center (DLR), such a stowing and deployment process is analyzed. It is based on a combination of zig-zag folding and coiling of triangular sail segments spanned between crossed booms. The deployment geometry and forces introduced by the mechanism considered are explored in order to reveal how the loads are transferred through the membranes to structural components such as the booms. The folding geometry and force progressions are described by function compositions of an inverse trigonometric function with the considered trigonometric function itself. If these functions are evaluated over several periods of the trigonometric function, a non-smooth oscillating curve occurs. Depending on the trigonometric function, these are often vividly described as zig-zag or sawtooth functions. The developed functions are applied to the Gossamer-1 design. The deployment geometry reveals a tendency that the loads are transferred along the catheti of the sail segments and therefore mainly along the boom axes. The load introduced by the spool deployment mechanism is described. By combining the deployment geometry with that load, a prediction of the deployment load progression is achieved. The mathematical description of the stowing and deployment geometry, as well as the forces inflicted by the mechanism provides an understanding of how exactly the membrane deploys and through which edges the deployment forces are transferred. The mathematical analysis also gives an impression of sensitive parameters that could be influenced by manufacturing tolerances or unsymmetrical deployment of the sail segments. While the mathematical model was applied on the design of

    Fermentation of meat is a traditional preservation method used widely for improving quality and shelf life of fermented meat products. Fermentation of meat causes a number of physical, biochemical, and microbial changes, which eventually impart functional properties, sensory characteristics, and nutritional aspects to these products and inhibit the growth of various pathogenic and spoilage microorganisms. These changes include acidification (carbohydrate catabolism), solubilization and gelation of myofibrillar and sarcoplasmic proteins of muscle, degradation of proteins and lipids, reduction of nitrate into nitrite, formation of nitrosomyoglobin, and dehydration. Dry-fermented sausages are increasingly being used as carrier of probiotics. The production of biogenic amines during fermentation can be controlled by selecting proper starter cultures and other preventive measures such as quality of raw materials, hygienic measures, temperature, etc.

    A variety of clinical process indicators exists to measure the quality of care provided by maternal and neonatal health (MNH) programs. To allow comparison across MNH programs in low- and middle-income countries (LMICs), a core set of essential process indicators is needed. Although such a core set is available for emergency obstetric care (EmOC), the 'EmOC signal functions', a similar approach is currently missing for MNH routine care evaluation. We describe a strategy for identifying core process indicators for routine care and illustrate their usefulness in a field example. We first developed an indicator selection strategy by combining epidemiological and programmatic aspects relevant to MNH in LMICs. We then identified routine care process indicators meeting our selection criteria by reviewing existing quality of care assessment protocols. We grouped these indicators into three categories based on their main function in addressing risk factors of maternal or neonatal complications. We then tested this indicator set in a study assessing MNH quality of clinical care in 33 health facilities in Malawi. Our strategy identified 51 routine care processes: 23 related to initial patient risk assessment, 17 to risk monitoring, 11 to risk prevention. During the clinical performance assessment a total of 82 cases were observed. Birth attendants' adherence to clinical standards was lowest in relation to risk monitoring processes. In relation to major complications, routine care processes addressing fetal and newborn distress were performed relatively consistently, but there were major gaps in the performance of routine care processes addressing bleeding, infection, and pre-eclampsia risks. The identified set of process indicators could identify major gaps in the quality of obstetric and neonatal care provided during the intra- and immediate postpartum period. We hope our suggested indicators for essential routine care processes will contribute to streamlining MNH program

Although Garrett Canada has always been a profitable division with a solid market share, the changing and turbulent business environment and globalization of the aerospace industry has created new demands and challenges. The marketplace is demanding faster introduction of new products, as well as shorter leadtimes for repairs and spares. It was recognized that reducing cycle times for new products and for ongoing production would not only satisfy our customers, it would also enhance our business performance through reduced inventories, lower past due, and more responsiveness to change. It was evident that drastic function changes were required if we were to maintain our position as a premier aerospace supplier. The challenge was to convert a stable, somewhat slow-paced work environment with strong functional boundaries into a boundaryless world class team functioning in a total quality environment and focused on customer satisfaction. Complete and uncompromised customer satisfaction has become our driving force, with Total Quality being our engine to continuously improve our processes and increase our speed. The way in which this transition has been brought about is the subject of this presentation.

    Recent studies suggest that psychotic-like experiences may also act as markers for non-psychotic psychiatric disorders, which may indicate that the focus of research in individuals at high risk (HR) for psychosis needs updating. In this study we thoroughly examined the clinical and functional characteristics of a consecutive cohort of young people at HR for psychosis and compared them to a matched sample of healthy volunteers. Between February 2010 and September 2012 60 help-seeking HR individuals, aged 16-35, were recruited from CAMEO Early Intervention in Psychosis Service, Cambridgeshire, UK. Forty-five age- and gender-matched healthy volunteers were randomly recruited from the same geographical area. Sociodemographic, psychiatric morbidity, functioning and quality of life measures were compared between both groups. HR individuals suffered a wide range of DSM-IV psychiatric disorders, mainly within the affective and anxiety diagnostic spectra. In comparison to healthy volunteers, young people at HR reported more suicidal ideation/intention, depressive and anxiety symptoms and presented with remarkably poor functioning and quality of life. The presence of co-morbid moderate or severe depressive and anxiety symptoms was common in our sample of young people at enhanced risk for psychosis. A HR mental state may be associated not only with an increased risk for psychosis, but also other psychiatric disorders. Our findings may have implications for the future implementation of therapeutic interventions that this population could benefit from. Copyright © 2013 Elsevier B.V. All rights reserved.

    To evaluate correlations between longitudinal changes in neuro-ophthalmologic measures and quality of life (QOL) and disability in patients with multiple sclerosis (MS), using optical coherence tomography (OCT), visual evoked potentials (VEP), and visual field examination. Fifty-four patients with relapsing-remitting MS were enrolled in this study and underwent Multiple Sclerosis Quality of Life questionnaire (54 items) (MSQOL-54) and Expanded Disability Status Scale (EDSS) evaluation, as well as complete neuro-ophthalmologic examination including visual field testing and retinal nerve fiber layer (RNFL) measurements using Cirrus and Spectralis OCT and VEP. All patients were re-evaluated at 12, 24, and 36 months. Logistical regression was performed to analyze which measures, if any, could predict QOL. Overall, RNFL thickness results at the baseline evaluation were significantly different from those at 3 years (p ≤ 0.05), but there were no differences in functional measures (visual acuity, contrast sensitivity, color vision, visual field, and VEP). A reduced MSQOL-54 score was associated with an increase in EDSS score and a decrease in both functional and structural parameters. Patients with longer MS duration presented with a lower MSQOL-54 score (reduction in QOL). Patients with progressive axonal loss as seen in RNFL results had a lower QOL and more functional disability.

    Full Text Available Abstract Background Scoring functions, such as molecular mechanic forcefields and statistical potentials are fundamentally important tools in protein structure modeling and quality assessment. Results The performances of a number of publicly available scoring functions are compared with a statistical rigor, with an emphasis on knowledge-based potentials. We explored the effect on accuracy of alternative choices for representing interaction center types and other features of scoring functions, such as using information on solvent accessibility, on torsion angles, accounting for secondary structure preferences and side chain orientation. Partially based on the observations made, we present a novel residue based statistical potential, which employs a shuffled reference state definition and takes into account the mutual orientation of residue side chains. Atom- and residue-level statistical potentials and Linux executables to calculate the energy of a given protein proposed in this work can be downloaded from http://www.fiserlab.org/potentials. Conclusions Among the most influential terms we observed a critical role of a proper reference state definition and the benefits of including information about the microenvironment of interaction centers. Molecular mechanical potentials were also tested and found to be over-sensitive to small local imperfections in a structure, requiring unfeasible long energy relaxation before energy scores started to correlate with model quality.

  4. Does colostomy irrigation affect functional outcomes and quality of life in persons with a colostomy?

    Colostomy irrigation may be used by patients with colostomies to regulate bowel evacuations by stimulating emptying of the colon at regularly scheduled times. This Evidence-Based Report Card reviews the effect of colostomy irrigation on frequency of bowel evacuation, flatus production, odor, and health-related quality of life. We systematically reviewed the literature for studies that evaluated health-related quality of life in persons aged 18 years or older with colostomies of the sigmoid or descending left colon. A professional librarian performed the literature search, which yielded 499 articles using the search terms "colostomy," "colostomies," "therapeutic irrigation," "irrigation," and "irrigator." Following title and abstract reviews, we identified and retrieved 4 studies that met inclusion criteria. Colostomy irrigation reduces the frequency of bowel evacuations when compared to spontaneous evacuation and containment using a pouching system. Regular irrigation is associated with reductions in pouch usage. This change in bowel evacuation function frequently results in absence of bowel evacuations for 24 hours or longer, enabling some to discontinue ongoing use of a pouching system. Subjects using CI report reductions in flatus and odors associated with presence of a colostomy. One study was identified that found persons using CI reported higher health-related quality of life than did those who managed their colostomies with spontaneous evacuation using the Digestive Disease Quality of Life-15, but no differences were found when health-related quality of life was measured using the more generic instrument, the Medical Outcomes Study: Short Form-36. Instruction on principles and techniques of colostomy irrigation should be considered when managing patients with a permanent, left-sided colostomy.

    Data on fertility rates and medication safety in men with inflammatory bowel disease (IBD) are limited. The aim of this study was to evaluate whether there is a seminal alteration in patients with IBD and, if so, to evaluate the mechanisms that may play a role according to what has been described in the literature. Its secondary aim was to evaluate the impact on male sexual function of IBD. Multicenter, cross-sectional, case series study comparing men with IBD and control subjects. Semen analysis was performed according to the recommendations of World Health Organization. The impact on male sexual function was evaluated with the International Index of Erectile Function questionnaire. On multivariate analysis, patients with Crohn's disease had lower sperm concentrations compared with those with ulcerative colitis (median [interquartile range], 34.5 [19.2-48] versus 70 [34.5-127.5], P = 0.02) and lower seminal zinc levels (mean ± SD, 1475 ± 235 μmol/L versus 2221 ± 1123 μmol/L, P = 0.04). Patients with Crohn's disease on anti-tumor necrosis factor treatment had better progressive motility (mean ± SD, 56.7 ± 17.7 versus 35.1 ± 22.1, P = 0.01) and sperm morphology (14.4 ± 7.1 versus 7.6 ± 4.9, P = 0.04) than those who were not on anti-tumor necrosis factor. Regarding sexual function, no significant differences were found across patients with IBD and control subjects. Men with Crohn's disease showed a trend toward poorer semen quality than those with ulcerative colitis. Treatment with anti-tumor necrosis factor drugs does not seem to be associated with poor sperm quality. In patients in clinical remission, male sexual function is not affected by IBD.

    To compare the impact of first eye versus second eye cataract surgery on visual function and quality of life. Cohort study. A total of 328 patients undergoing separate first eye and second eye phacoemulsification cataract surgeries at 5 veterans affairs centers in the United States. Patients with previous ocular surgery, postoperative endophthalmitis, postoperative retinal detachment, reoperation within 30 days, dementia, anxiety disorder, hearing difficulty, or history of drug abuse were excluded. Patients received complete preoperative and postoperative ophthalmic examinations for first eye and second eye cataract surgeries. Best-corrected visual acuity (BCVA) was measured 30 to 90 days preoperatively and postoperatively. Patients completed the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ) 30 to 90 days preoperatively and postoperatively. The NEI-VFQ scores were calculated using a traditional subscale scoring algorithm and a Rasch-refined approach producing visual function and socioemotional subscale scores. Postoperative NEI-VFQ scores and improvement in NEI-VFQ scores comparing first eye versus second eye cataract surgery. Mean age was 70.4 years (±9.6 standard deviation [SD]). Compared with second eyes, first eyes had worse mean preoperative BCVA (0.55 vs. 0.36 logarithm of the minimum angle of resolution (logMAR), P < 0.001), greater mean BCVA improvement after surgery (-0.50 vs. -0.32 logMAR, P < 0.001), and slightly worse postoperative BCVA (0.06 vs. 0.03 logMAR, P = 0.039). Compared with first eye surgery, second eye surgery resulted in higher postoperative NEI-VFQ scores for nearly all traditional subscales (P < 0.001), visual function subscale (-3.85 vs. -2.91 logits, P < 0.001), and socioemotional subscale (-2.63 vs. -2.10 logits, P < 0.001). First eye surgery improved visual function scores more than second eye surgery (-2.99 vs. -2.67 logits, P = 0.021), but both first and second eye surgeries resulted in similar

    Post-traumatic stress symptoms (PTSS), occurring in 15% of combat-exposed military personnel, are associated with a decrease in couples' relationship quality. The purpose of this analysis was to describe reintegration in Army couples with high couple functioning, despite PTSS in one or both partners. Reintegration refers to readjustment after deployment; returning to previous role(s). In a mixed-methods case study of Army couples with a history of combat deployment, we used existing quantitative data to define sampling boundaries, select cases, and guide interviews. Couples scoring high on couple functioning, resilience, and couple satisfaction were interviewed (N = 5 couples, 10 participants). "Rekindling marriage" required strategies to overcome challenges during couple reintegration. For participants as individuals, those strategies were allowing negative emotions, giving each other time and space to do the work of rediscovery and accepting a changed reality, and recognizing and addressing individual needs of the other. As couples, strategies were to go with the flow, open your heart, become best friends, maintain trust, and communicate effectively. As families, strategies were to normalize schedules and protect family time. Findings offer a preliminary basis for interventions to promote strong relationships for military couples with PTSS.

    Full Text Available Abstract Despite a pool of unemployed health staff available in Kenya, staffing levels at most facilities were only 50%, and maldistribution of staff left many people without access to antiretroviral therapy (ART. Because in the current system it takes one to two years to fill vacant positions, even when funding is available, an emergency approach was needed to fast-track the hiring and deployment process. A stakeholder group was formed to bring together leaders from several sectors to design and implement a fast-track hiring and deployment model that would mobilize 830 additional health workers. This model used the private sector to recruit and deploy new health workers and manage the payroll and employment contracts, with an agreement from the government to transfer these staff to the government payroll after three years. The recruitment process was shortened to less than three months. By providing job orientation and on-time pay checks, the program increased employee retention and satisfaction. Most of the active roadblocks to changes in the health workforce policies and systems are 'human' and not technical, stemming from a lack of leadership, a problem-solving mindset and the alignment of stakeholders from several sectors. It is essential to establish partnerships and foster commitment and collaboration to create needed change in human resource management (HRM. Strengthening appointment on merit is one of the most powerful, yet simplest ways in which the health sector and governments that seek to tackle the challenges of corruption and poor governance can improve their image and efficiency. The quality and integrity of the public health sector can be improved only through professionalizing HRM, reformulating and consolidating the currently fragmented HR functions, and bringing all the pieces together under the authority and influence of HR departments and units with expanded scopes. HR staff must be specialists with strategic HR functions

    The aim of this study is to evaluate a possible relationship between the level of anticipated discrimination with severity of symptoms and functionality. We included 103 patients with schizophrenia. Severity of symptoms was measured by PANSS and Calgary Depression Scale for Schizophrenia. Quality of life (QL) and functionality were measured by using QLS, PSP and Functional Remission of General Schizophrenia Scale (FROGS). Anticipated/experienced discrimination was evaluated with four selected items from Discrimination and Stigma Scale. First, variables related to each item were determined by using t-test and later the variables that have an independent contribution to anticipated discrimination subscale of DISC were evaluated with linear regression analysis. Results showed that those who stated that they felt the need to conceal their diagnosis more had shorter duration of illness, lower PANNS scores, higher scores on professional performance subscale of QLS, a lower number of suicide attempts and higher current employment rates. Participants who reported that they had been avoided or shunned more had higher depression scores. While patients with lower level of functionality tended to stop themselves more, patients with high level of functionality tended to conceal their diagnosis.

    Why do functional assessments in patients with end-stage renal disease (ESRD) matter? Multiple studies show that new dialysis patients undergo a substantial decline among activities of daily living. Moreover, poor functional status in ESRD patients is associated with early morality. That is why CMS has developed new criteria to assess ESRD patients in regards to their functional, psychologic, and cognitive capabilities. Functional assessments by health providers have been used in field of Rehabilitation Medicine for over 50 years; rehabilitation physicians have found them effective in establishing goals and monitoring improvement. Assessments can provide guidance by identifying the needs and types of intervention most suited for patients. Impairments can be addressed with referrals to physical therapy for gross motor issues, occupational therapy for self-care problems, psychiatry for mental disorders, and neurology for cognitive deficits. The more accurate the assessments over time, the more targeted and effective the therapies become. We believe that the new CMS goals to assess functionality will improve ESRD patient's quality of life, longevity, and long-term healthcare costs.

    This study aimed to identify profiles of functioning and quality of life (QOL) in depression (MDD), bipolar disorder (BD) and healthy adults, as well as the clinical, demographic and cognitive variables associated with each of these profiles. Participants completed the WHODAS 2.0 and WHOQOL-BREF, which were submitted to latent profile analysis. The four cluster solution provided the best fit for our data. Cluster 1 consisted mostly of healthy adults, and had the highest functioning and QOL. Clusters 2 contained older patients with subclinical depressive symptoms and psychiatric comorbidities, whose impairments in QOL and functioning were associated with mood symptoms and several cognitive abilities. Patients with MDD, BDI or BDII with mild to moderate depression, such as those in cluster 3, may benefit more significantly from interventions in cognitive flexibility, inhibition, planning, and sustained attention. Lastly, patients with mood disorders and clinically significant levels of depression, as well as a history of suicide attempts, like those in cluster 4, may benefit from interventions aimed at working memory, inhibitory control, and cognitive flexibility; that is, the three core executive functions. These findings should be further investigated, and used to guide treatments for patients with mood disorders and different patterns of functional impairment.

    [Purpose] The aim of this study was to assess patients' health-related quality of life, compare it with a healthy age-matched population, and examine associations between functional ability and quality of life among juvenile rheumatoid arthritis (JRA) patients. [Subjects and Methods] The study participants were 26 JRA patients and 25 controls. The Childhood Health Assessment Questionnaire and the Pediatric Quality of Life Inventory 4.0 Generic Core Scales were used to evaluate functional ability and health-related quality of life, respectively. [Results] Functional ability scores averaged 0.37 in the JRA group and 0.08 in the control group. There were significant between-group differences in functional ability scores in the overall cohort and in the subgroup of participants aged 14-16 years. Health-related quality of life scores were significantly lower in the JRA group than in the control group (68.39 vs. 85.17). In the JRA group, functional ability was statistically positively correlated with health-related quality of life. [Conclusion] We conclude that the mental state of adolescents with JRA affects their particular functional abilities. Subjects in the 14-16 age group who had a longer disease duration and higher difficulty scores showed a lower health-related quality of life than children in the other age groups.

    1991-01-01

    An innovative Deployment and Retraction hinge Mechanism (DARM) in the frame of a technological program is examined. The mechanism includes two restraint/release devices, which enable it to be stable in its stowed or deployed position while sustaining all associated loads, and to carry its payload by remote command. The main characteristics of the DARM are as follows: deployment and retraction movements are spring actuated; the available amount of functional sequences is almost unlimited; and no use of electrical motors is made. These features were accomplished by: the application of a special kinematic scheme to the mechanical connection between the spring motor and the swivel head arm; and the use of shape memory alloys (SMA) actuators for both release and spring recharge functions. DARM is thus a mechanism which can find many applications in the general space scenario of in-orbit maintenance and servicing. In such a frame, the DARM typical concept, which has a design close to very simple one-shot deployment mechanisms, has a good chance to replace existing analog machines. Potential items that could be moved by DARM are: booms for satellite instruments; antenna reflector tips; entire antenna reflectors; and solar panels.

    Objectives The aims of this study were to evaluate correlates and predictors of life functioning and quality of life in bipolar disorder during a comparative effectiveness trial of moderate doses of lithium. Methods In the Lithium treatment moderate-dose use study (LiTMUS), 283 symptomatic outpatients with bipolar disorder type I or II were randomized to receive lithium plus ”optimal personalized treatment (OPT), or OPT alone. Participants were assessed using structured diagnostic interviews, clinician-rated blinded assessments, and questionnaires. We employ linear mixed effects models to test the effect of treatment overall and adjunct lithium specifically on quality of life or functioning. Similar models are used to examine the association of baseline demographics and clinical features with quality of life and life functioning. Results Quality of life and impaired functioning at baseline were associated with lower income, higher depressive severity, and more psychiatric comorbid conditions. Over six months, patients in both treatment groups improved in quality of life and life functioning (p-values 0.05). Within the lithium group, improvement in quality of life and functioning were not associated with concurrent lithium levels at week 12 or week 24 (p-values > 0.05). Lower baseline depressive severity and younger age of onset predicted less improvement in functioning over six months. Conclusions Optimized care for bipolar disorder improves overall quality of life and life functioning, with no additional benefit from adjunct moderate doses of lithium. Illness burden and psychosocial stressors were associated with worse quality of life and lower functioning in individuals with bipolar disorder. PMID:25194782

    Full Text Available Education is described as the development of desirable qualities in people. Quality education is fundamental to National Transformation because it depends on literate and skilled citizenry. This paper examines the study of physics as crucial for any nation that wants to maintain its leads among the community of nationsand as tools for National Transformation. Obviously the Nation as well as the Education sector is faced with various challenges, ranging from conflicts, strikes, instability, corruption, lack of motivation for teaching personnel and inadequate funding among others. Quality and functional physics Education is an education that is effective, efficient, sustainable and relevant to the evolving individual and societal needs, and ensures equality among the citizens is directly needed for a turn around. Also it can provide knowledge and skills which produce values and attitude that offer a basis for transforming conflict itself. This work employs the use of secondary sources of data and content analysis and also comes up with suggestions that there is absolute need for Governments at all levels to be committed to the implementation of educational policies especially physics education, for without physics, the technological culture of the citizens cannot be firmly rooted. Collaboration between the Federal, States, Local Governments and relevant educational bodies should also be strengthened.

    Chronic obstructive pulmonary disease (COPD) is a progressive, inflammatory condition, involving airways and lung parenchyma. The disease leads to airflow limitation, and pulmonary hyperinflation, resulting in dyspnea, decreased exercise tolerance, and impaired quality of life. COPD pharmacotherapy guidelines are based on a combination of long-acting beta2-agonists (LABA), long-acting antimuscarinic agents (LAMA) and methyloxantins. Recently, indacaterol, ultralong acting beta2-agonist, has been introduced. The aim of our study was to assess the impact of indacaterol add-on therapy on lung function, exercise tolerance and quality of life of COPD patients. Thirty four COPD patients, receiving stable bronchodilator therapy were randomly allocated into two arms of add-on treatment (1:1 - indacaterol:placebo) for 3 months. Indacaterol replaced LABA in all patients receiving LABA. Spirometry, lung volumes, DLCO, St George's Respiratory Questionnaire (SGRQ) and 6 min Walk Distance (6MWD) were performed before and after therapy. We found that in the indacaterol group FEV1 did not changed significantly. However, there were significant improvements in ERV, 6MWD, and 6MWD-related dyspnea score. We also found that the degree of desaturation before and after 6MWD, and fatigue levels significantly improved in the indacaterol group. The patients' quality of life also changed favorably in the indacaterol treatment arm. We conclude that the add-on therapy with indacaterol exerts positive effects in COPD patients.

    Full Text Available The objective of the study was to evaluate thesurface quality of commercially producedparticleboard and medium density fiberboard (MDFpanels as function of weathering. Four types ofpanels were exposed to three weathering cycles ofwater soaking, freezing, and heat exposures todetermine the influence of such conditions on theirsurface roughness. The stylus type equipment wasemployed to determine the roughness of controlsamples as well as after each one of the weatheringcycle. Two accepted roughness parameters, namelyaverage roughness (Ra and mean peak-to-valleyheight (Rz were used for the measurement of overallroughness changes of the specimens. Surfaces ofboth types of particleboard samples were adverselyinfluenced as a result of first cycle of weathering andthen they were reconditioned and subjected to twomore exposure cycles. In the case of MDF samplesthe first and the second weathering exposuresincreased roughness of the samples but they wererebalanced at the end of the third cycle. The highestRa value of 17.16μm was determined forparticleboard samples exposed to the first exposurecycle. Overall surface quality of MDF samples wereless influenced than those of particleboardspecimens. Based on the findings in this work itappears that stylus technique can effectively be usedto evaluate surface quality of such composite panelsas they are subjected to different weatheringexposures.

The resultant work is of significant contribution to problem decision makings in the field of quality assessment of audiovisual translation (AVT. The outcome of this paper is the result of accumulated working experience in this domain. The relevant errors are related to syntax, spelling, style, length of sentences, lack of clarity, and gender-related issues. These errors though made by one subtitler who has translated the animation feature film Pocahontas II released in 2012, are still typical and therefore a thorough investigation has been done and a set of linguistic rules has been suggested as a guideline for the audiovisual industry. These rules are to be added to the technical and software requirements sent by subtitling companies (such as the number of characters per line, the font, the reading speed per minute, and punctuation. This set of rules helps monitor the quality of the subtitled target text (TT.     Keywords: audiovisual translation, subtitling, quality assessment, practical functional approach, Arabic-English simulation

    Subtalar arthrodesis is a common salvage operation for posttraumatic subtalar arthritis, a condition frequently seen in patients who suffered major trauma. Functional outcomes in trauma patients may be influenced by concomitant injuries and the severity of the initial trauma. The aim of this study was to evaluate quality of life and functional outcomes of subtalar arthrodesis for posttraumatic arthritis in patients with severe or complex foot injuries. This is a retrospective single center study with prospective follow-up. Patients who underwent subtalar arthrodesis for posttraumatic arthritis between 2000 and 2016 were included and invited to complete a Maryland Foot Score (MFS), a EuroQol five-dimensional (EQ-5D™) and Visual Analog Scale (EQ-VAS™) questionnaire, and four additional questions. Forty patients were included in the study, functional outcome scores were available for 30 patients (response rate 75%). Additional surgery of the fused foot was performed in 29 patients and 15 suffered multiple lower extremity injuries. Six patients were polytraumatized. Ninety percent of all patients would recommend the procedure to others, walking abilities improved in 69% and less pain was experienced in 76%. Median MFS score was 61 (IQR 53-72). Quality of life was significantly lower when compared to a reference population (p<0.001). Satisfaction was high, as 90% of all patients would recommend subtalar fusion to others, even though the relatively poor outcome measures would suggest differently. Existing functional outcomes measures were influenced by concomitant injuries and additional procedures. This demands development of instruments suitable for severely injured patients with multiple or complex injuries. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Background. Massage therapy is a noninvasive treatment that many individuals with multiple sclerosis (MS use to supplement their conventional treatment. Objective. We hypothesize that massage therapy will improve the leg function and overall quality of life (QoL of MS patients. Design. A two-period (rest, massage crossover design was used. Twenty-four individuals with MS ranging from 3.0 to 7.0 on the Expanded Disability Status Scale (EDSS received Swedish massage treatments for four weeks. Exercise capacity and leg function as well as QoL were assessed using the Six-Minute Walk Test (6MWT and the Hamburg Quality of Life in Multiple Sclerosis (HAQUAMS instrument, respectively. Assessments were measured before and after a massage period and a rest period where no massages were employed. Results. The results displayed no significant changes in 6MWT distances or HAQUAMS scores. However, the participants perceived improvement in overall health as expressed in written comments. Conclusions. Massage is a safe, noninvasive treatment that may assist MS patients in managing the stress of their symptoms. Future studies with larger sample size and cortisol measures are warranted.

  14. Optimization of correlated multi-response quality engineering by the upside-down normal loss function

    2016-08-01

    Most of the published literature on robust design is basically concerned with a single response. However, the reality is that common industrial problems usually involve several quality characteristics, which are often correlated. Traditional approaches to multidimensional quality do not offer much information on how much better or worse a process is when finding optimal settings. Köksoy and Fan [Engineering Optimization 44 (8): 935-945] pointed out that the upside-down normal loss function provides a more reasonable risk assessment to the losses of being off-target in product engineering research. However, they only consider the single-response case. This article generalizes their idea to more than one response under possible correlations and co-movement effects of responses on the process loss. The response surface methodology has been adapted, estimating the expected multivariate upside-down normal loss function of a multidimensional system to find the optimal control factor settings of a given problem. The procedure and its merits are illustrated through an example.

    2011-09-01

    Full Text Available Demanding surrounding makes it necessary for an organisation to adapt and restructure constantly. Therefore, it is essential for an organisation to acquire competence allowing to use opportunities and avoid dangers which happen, among others, because of changeability of relations between it and people interested. Adaptation to the changes which occur in the spheres mentioned in the following lines constitutes the challenge. The changes refer to the following spheres: economical, technological, international or legal and political. It requires systematic and comprehensive organisation development, which becomes possible due to the use of The Management Model of the Polish Quality Award which is perceived as a tool optimising the quality of functioning and development of an organisation. The use of the model's criteria as a tool supporting development and mistake correction gives a chance to gain competitive predominance of an organisation. This leads to effective and efficient way of conducting self-assessment as well as systematic identification of weak points of an organisation, which, in turn, directs towards the facilitation of pinpointing the direction of its functioning.

    Children with epilepsy are vulnerable to executive dysfunction, but the relationship between executive functioning (EF) and quality of life (QOL) in children with epilepsy is not fully delineated. This exploratory study elucidated the relationship between ecological EF and QOL in pediatric intractable epilepsy. Fifty-four consecutively referred pediatric epilepsy surgery candidates and their parents were administered IQ measures, the Behavior Rating Inventory of Executive Function (BRIEF), and the Quality of Life in Childhood Epilepsy (QOLCE) as part of a comprehensive neuropsychological evaluation. A significant difference was found in QOL between those with and without clinical impairments on the BRIEF [t(52)=3.93; p<.001]. That is, children with executive dysfunction had lower overall QOL. All seizure variables and BRIEF scales were associated with overall QOL [F(12, 40)=6.508; p=.001; R(2)=.661]. Working memory from the BRIEF was the most frequently elevated scale in our sample (57%). Those with executive dysfunction had 9.7 times the risk of having poor QOL. Poor EF control according to behavior ratings is significantly related to QOL in intractable pediatric epilepsy. Identification of executive dysfunction in home environments is an essential component of presurgical evaluations and target for intervention, which may improve QOL. Copyright © 2016 Elsevier Inc.

    A 56-year-old man diagnosed in 2003 as having Hoehn & Yahr stage III Parkinson's disease (PD) came to our clinic in 2012 with slurred speech, right-sided bradykinesia, erectile dysfunction, rigidity, emotional instability and depression. His PD showed progressive signs with postural instability, moderate bilateral signs, and he rated 80% on the Schwab & England Activities of Daily Living Scale. A modified protocol of electroacupuncture was administered for a period of 5 weeks, six times per week, with each session lasting for 30 min. Assessments were based on the Berg Balance Scale (BBS) and Parkinson's Disease Questionnaire-39 (PDQ-39) items, a disease-specific measure of subjective health status. He showed improvement on the BBS, suggesting improved functional status. His quality of life showed improvement particularly on the 'activities of daily living', 'cognition' and 'communication' dimensions of the PDQ-39. Acupuncture treatments in animal experiments have generated valuable mechanistic insights that could be relevant to PD, for example, demonstrating its neuroprotective potential from stimulation of various neuroprotective agents. The literature also suggests acupuncture may play a role in the improvement of motor function and quality of life in PD. Acupuncture is tolerated well by individuals with PD and should be considered as an integrative approach for their symptomatic management.

    This paper aims to test a new physically oriented approach to viticulture zoning at the farm scale, strongly rooted on hydropedology and aiming to achieve a better use of environmental features with respect to plant requirement and wine production. The physics of our approach is defined by the use of soil-plant-atmosphere simulation models which applies physically-based equations to describe the soil hydrological processes and solves soil-plant water status. This study (ZOVISA project) was conducted in a farm devoted to high quality wines production (Aglianico DOC), located in South Italy (Campania region, Mirabella Eclano-AV). The soil spatial distribution was obtained after standard soil survey informed by geophysical survey. Two Homogenous Zones (HZs) were identified; in each one of those a physically based model was applied to solve the soil water balance and estimate the soil functional behaviour (crop water stress index, CWSI) defining the functional Homogeneous Zones (fHzs). In these last, experimental plots were established and monitored for investigating soil-plant water status, crop development (biometric and physiological parameters) and daily climate variables (temperature, solar radiation, rainfall, wind). The effects of crop water status on crop response over must and wine quality were then evaluated in the fHZs. This was performed by comparing crop water stress with (i) crop physiological measurement (leaf gas exchange, chlorophyll a fluorescence, leaf water potential, chlorophyll content, LAI measurement), (ii) grape bunches measurements (berry weight, sugar content, titratable acidity, etc.) and (iii) wine quality (aromatic response). Eventually this experiment has proved the usefulness of the physical based approach also in the case of mapping viticulture microzoning.

    Ciliated protozoa play important roles in micro-ecosystems, especially in marine biotopes. However, few studies have been carried out on the periphytic, or aufwuch, forms in mariculture waters so far. In this study, we sampled periphytic ciliate communities in two closed mariculture ponds (ponds CP1 and CP2) and a natural seawater reservoir (pond RP) using a glass slide method to evaluate their colonizing processes and general ecological features, as well as their application as water quality indicators. We analyzed species compositions, structural parameters (species number, richness, diversity, evenness, abundance and dBP) and functional parameters (G, Seq, and T90%). Pond RP was characterized by higher levels of structural parameters (except for abundance and dBp) and more equal proportion of the major taxonomic groups. The values of 5eq were significantly higher in pond RP and similar in both pond CP1 and CP2. It was also demonstrated that environmental factors, including NO2-H, NO3-H, NH3-H, soluble reactive phosphate, temperature and pH, were the first principal factors affecting the communities. Among them, temperature and chemical factors were all significantly and negatively correlated with species number (P<0.01), richness (P<0.01), diversity (P<0.01), and positive correlated with abundance (P<0.01). Opposite correlations between pH and structural parameters were observed. This study showed that there were significant differences in species composition, structural parameters and functional parameters of the periphytic ciliate communities among the ponds, which were in agreement with the water quality. Results of this study confirmed the periphytic ciliate communities to be useful bioindicators of water quality in intensive mariculture waters.

    Protein levels and quality in cat food can vary significantly and might affect immune function in various ways. In the present study, 3 diets with a low protein quality (LQ) and 3 diets with a high protein quality (HQ) were offered to 10 healthy adult cats for 6 weeks each, using a randomized cross-over design. The LQ and HQ diets differed in the collagen content and had low (36.7% and 36.2%), medium (45.0% and 43.3%) and high (56.1% and 54.9%) protein levels. At the end of each feeding period, blood was collected for phenotyping of leukocyte subsets, lymphocyte proliferation assay and cytokine measurements, phagocytosis assay and differential blood count. The results demonstrated no group differences for numbers of CD4+CD8-, CD4+CD8+, CD4-CD8+, MHCII+, CD21+, SWC3+ and CD14+ cells in the blood of the cats. Proliferative activity of lymphocytes when stimulated with pokeweed mitogen, Concanavalin A and Phytohemagglutinin, M form did not differ depending on the dietary protein concentration and quality. Concentrations of tumor necrosis factor alpha and interferon gamma in the supernatant of the proliferation assay were also not affected by the dietary treatment. Blood monocyte phagocytic activity was higher (P = 0.048) and cell numbers of eosinophilic granulocytes in the blood were lower (P = 0.047) when cats were fed the low protein diets. In conclusion, only a few differences in feline immune cell populations and activity depending on dietary protein supply could be detected. However, the observed increase of eosinophilic granulocytes by a higher protein intake indicates an activation of immunological mechanisms and requires further investigation. PMID:28072882

    Urban and suburban streams often exhibit frequent flash floods and low water quality, but surprisingly few studies of these systems attempt to resolve the relative contributions of different runoff fractions and their associated geochemistry. This study deliberately examined concurrent responses in three watersheds and two subbasins along a gradient of increasing impervious surface area in and around highly urbanized Saint Louis, Missouri, USA, to quantify changes in the relative contributions of pre-event (baseflow) and event (runoff) water to streamflow during flooding using hydrograph separations. Our high frequency monitoring of stable isotopes ratios (δ2H and δ18O) and water quality (temperature, dissolved O2, pH, turbidity, specific conductivity, concentrations of Cl- and nutrients, and bacterial loads) quantify large hydrologic and geochemical differences across the land use gradient. Following precipitation events, floods on a rural stream feature slow flow responses, hydrographs with low peak discharges and long lag times, high baseflow contributions, and small geochemical variations. In contrast, the flows of an urban stream and its tributary respond in a flashier manner, with peak flows that are nearly 10 times higher, average lag times that decrease by 85%, and event water contributions that are 2 times higher compared to the rural stream. The urban streams also exhibit large fluctuations in geochemistry, often with 5 times the variability of the rural end-member. These large geochemical changes in urban streams following storms are paralleled by more chaotic diurnal and seasonal variations. Importantly, we find that reduced baseflow as a function of increasing impervious surface area is not linear; thus, the hydrology of suburban streams is less impacted than would be predicted by impervious surface alone. This non-linear relationship with impervious surface area is also observed in some of the geochemical responses to flooding, and therefore

    This report summarizes user feedback data collected during a recent Accelerated Site Technology Deployment (ASTD) project: the Fluor Fernald ASTD Technology Deployment Project from May, 1999 through September, 2000. The main goal of the ASTD project was to use the ''Fernald approach'' to expedite the deployment of new or innovative technologies with superior safety, cost, and/or productivity benefits to Department of Energy (DOE) facilities. The Fernald approach targets technology end-users and their managers and directly involves them with hands-on demonstrations of new or innovative technologies during technology transfer sessions. The two technologies deployed through this project were the Personal Ice Cooling System (PICS) and the oxy-gasoline torch. Participants of technology transfer sessions were requested to complete feedback surveys. Surveys evaluated the effectiveness of the Fernald approach to technology deployment and assessed the responsiveness of employees to new technologies. This report presents the results of those surveys.

    Full Text Available Objectives: Investigate gender related differences in somatic symptoms, severity of depression, quality of life (QOL, and functional impairment, and correlate somatic symptoms with QOL and functional impairment. Methods: This cross-sectional study was conducted with 100 consecutive outpatients seeking treatment for depressive disorder at district hospital psychiatric outpatient clinic, Kolar, Karnataka, India. This study utilised the Beck Depression Inventory II, Physical Distress Scale, Work and Social Adjustment Scale, and World Health Organization QOL BREF instrument. Results: Mean constipation scores and back pain scores were higher in women compared to men. There were no statistically significant differences between male and female patients with regard to depression scores, total somatic symptom scores, QOL, and functional impairment scores. Somatic symptoms scores are positively correlated with depression scores and functional impairment scores, and negatively correlated with QOL scores. Conclusion: Women had higher constipation and back pain scores compared to men. If the symptoms of same disease differ between men and women, this has important implications for the history collection, diagnosis, and treatment process.

    2015-01-01

    The functional method is a new test theory using a new scoring method that assumes complexity in test structure, and thus takes into account every correlation between factors and items. The main specificity of the functional method is to model test scores by multiple regression instead of estimating them by using simplistic sums of points. In order to proceed, the functional method requires the creation of hyperspherical measurement space, in which item responses are expressed by their correlation with orthogonal factors. This method has three main qualities. First, measures are expressed in the absolute metric of correlations; therefore, items, scales and persons are expressed in the same measurement space using the same single metric. Second, factors are systematically orthogonal and without errors, which is optimal in order to predict other outcomes. Such predictions can be performed to estimate how one would answer to other tests, or even to model one's response strategy if it was perfectly coherent. Third, the functional method provides measures of individuals' response validity (i.e., control indices). Herein, we propose a standard procedure in order to identify whether test results are interpretable and to exclude invalid results caused by various response biases based on control indices.

    The internal structure of the moons of Jupiter is an area of great interest. Seismic investigations, either in the long-period band of 0.1 to 1 Hz, or at shorter periods of 1 to 100 Hz, have been studied as a means to determine the depth of subsurface liquid water with a single, triaxial seismometer. A penetrometer would be an ideal deployment for such an instrument as it would ensure excellent coupling, minimise thermal variations, and substantially reduce the radiation environment during operation. A microseismometer is under development which combines the required sensitivity for identification of the ambient seismicity with the robustness to survive the shock of deployment. At the heart of the instrument is a single-crystal silicon suspension machined through the full thickness of a wafer resulting in a very high quality factor. The movement of the proof mass is determined by extremely sensitive capacitive array transducer. This transducer is coupled to readout and feedback electronics which are designed for very low power operation. A unique combination of open and closed loop feedback enables the instrument to operate over a wide range of tilt angles, a vital consideration for a penetrometer deployment. The current measured noise is 3 ng/sqrtHz at 20 s, with the capability of a further order of magnitude improvement. The suspension has been tested on rocket-sled impacts to simulate a penetrometer deployment, surviving shocks up to 14,000 g with suitable encapsulation. Such an instrument would have the capability for deployment on the surface of Europa or Ganymede and should provide vital information on the internal structure of these bodies.

    2016-10-03

    Purpose This paper aims to contribute to the debate concerning total quality management (TQM)-Lean strategy in public healthcare by analyzing the deployment path for implementation, the possible benefits that can be achieved and the encountered pitfalls. Design/methodology/approach Three case studies are drawn from three large Italian hospitals with more than 500 beds each and structured with many departments. The hospitals are located in Tuscany, Italy. These three hospitals have embraced TQM and Lean, starting from strategic objectives and their deployment. At the same time, they have also implemented many TQM-Lean tools. The case studies are based on interviews held with four managers in each of these three public hospitals. Findings Results from the interviews show that there is a specific deployment path for TQM-Lean implementation. The hospitals have also achieved benefits linked to patient satisfaction and improved organizational performances. Problems related to organizational and cultural issues, such as senior managers' commitment, staff management, manufacturing culture and tools adaptation, could affect the benefits. Research limitations/implications The research has been carried out in just three Italian public hospitals. Hence, similar investigations could be managed in other countries. Researchers could also use a larger sample and investigate these issues by means of quantitative inquiry. Practical implications Practitioners could try to apply the deployment path revealed by these case studies in other public and private hospitals. Originality/value The results of this research show that there is a specific, new deployment path for implementing TQM-Lean strategy in some public hospitals.

    Full Text Available Introduction: Plenty of information about health is available on the Internet; however, quality and legibility are not always evaluated. Knowledge regarding orofacial functions can be considered important for the population because it allows proper stimulus, early diagnosis, and prevention of the oral myofunctional alterations during early infancy. Objective: The aim was evaluate the quality, legibility, and range of Web sites available in Brazilian Portuguese regarding the orofacial functions. Methods: Selected Web sites with information directed to parents/caregivers of babies regarding breast-feeding, feeding after 6 months, deleterious oral habits, and breathing and speech were studied. The Web sites were evaluated through the application of Flesch Reading Ease Test and aspects of the Health on the Net (HON modified code (HONCode; the range of the subjects addressed was compared with other aspects of infant development. Results: From the access of 350 pages of the Internet, 35 Web sites were selected and 315 excluded because they did not meet the inclusion criteria. In relation to legibility, Web sites scored an average of 61.23% in the Flesch Test, and the application of the modified HONCode showed an average of 6.43 points; an average of 2.49 subjects were found per Web site evaluated, with information on breast-feeding being more frequent and subjects such as breathing and speech less frequent. Conclusions: Web sites that deal with orofacial functions presented standard legibility classification. Only half of the ethical principles were considered by the modified HONCode in their majority, and most addressed subjects after “breast-feeding” were presented with restricted range.

    The newly published Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) elevates the threshold of the ADHD age-of-onset criterion from 7 to 12 years. This study evaluated the quality of life and functional impairment of adults with ADHD who had symptoms onset by or after 7 years and examined the mediation effect of family function and anxiety/depression symptoms between ADHD diagnosis and quality of life and functional impairment. We assessed 189 adults with ADHD and 153 non-ADHD controls by psychiatric interview and self-administered reports on the Adult ADHD Quality of Life Scale, Weiss Functional Impairment Rating Scale, Family APGAR, and Adult Self Report Inventory-4. The ADHD group was divided into early-onset ADHD (onset ADHD (onset between 7 and 12 years, n=42). The mediation analysis was conducted to verify the mediating factors from ADHD to functional impairment and quality of life. The late-onset ADHD had more severe functional impairment at work and poorer family support than early-onset ADHD while they had comparable impairment at other domains. Less perceived family support and current anxiety/depressive symptoms partially mediated the link between ADHD diagnosis and quality of life/functional impairment both in early- and late-onset ADHD. Our data support decreased quality of life and increased functional impairment in adult ADHD, regardless of age of onset, and these adverse outcomes may be mediated by family support and anxiety/depression at adulthood. Our findings also imply that the new DSM-5 ADHD criteria do not over-include individuals without impairment.

    Deepwater deployment of offshore structures in different sea states was investigated. The whole deployment system was modeled as a lumped mass model, and discretization scheme for cable geometry and methodology for calculating the internal and external force acting on deploying cable were presented. The deployment model suitable for the time-varying length of deploying cable was specified. The free-surface flow fields together with the ship motions were used to calculate dynamic tension in the deploying cable during deployment of the structure. The deployment of deep sea mining system which was a typical subsea working system was employed. Based on lumped mass analysis model and parameters of deep sea mining system, numerical simulations were performed, and dynamic load and dynamic amplification factor (DAF) with different cable parameters, deploying velocities and sea states were obtained. It is shown that cable parameters and amplitudes of ocean waves can significantly influence the dynamic load and DAF, and the time-varying natural period of deploying system is a dominant factor, while the effect of deploying velocity is not obvious.

    With technological improvements in body armour and increasing use of improvised explosive devices, it is the injuries to head, face and neck are the cause for maximum fatalities as military personnel are surviving wounds that would have otherwise been fatal. The priorities of battlefield surgical treatment are to save life, eyesight and limbs and then to give the best functional and aesthetic outcome for other wounds. Modern day battlefields pose unique demands on the deployed surgical teams and management of head and neck wounds demands multispecialty approach. Optimal result will depend on teamwork of head and neck trauma management team, which should also include otolaryngologist. Data collected by various deployed HFN surgical teams is studied and quoted in the article to give factual figures. Otorhinolaryngology becomes a crucial sub-speciality in the care of the injured and military otorhinolaryngologists need to be trained and deployed accordingly. The otolaryngologist's clinical knowledge base and surgical domain allows the ENT surgeon to uniquely contribute in response to mass casualty incident. Military planners need to recognize the felt need and respond by deploying teams of specialist head and neck surgeons which should also include otorhinolaryngologists.

    To examine the development and determinants of long-term outcomes for earthquake victims with amputations, including physical function, pain, quality of life and life satisfaction. Prospective cohort study with 2-3 measurement points. A total of 72 people who underwent amputations following the 2008 Sichuan Earthquake and resided in Mianzhu County, Sichuan Province, China were enrolled in the study. Of these, 27 people were lost to follow-up. Data on pain (visual analogue scale) and physical function (Barthel Index) were collected at 3 measurement points (2009, 2010 and 2012), and data on quality of life (Medical Outcomes Short-Form 36) and life satisfaction (Life Satisfaction Questionnaire-11) were collected at 2 measurement points (2010 and 2012). Data were analysed with mixed effects regression. Pain severity declined significantly and physical function increased by 2012. Quality of life and life satisfaction remained relatively stable between 2010 and 2012, while quality of life was significantly lower than reference values from the general population. Illiteracy and lower extremity amputations were associated with lower quality of life and life satisfaction in several domains. While amputees' functioning and pain were improved over time, quality of life and life satisfaction did not change. Illiterate earthquake survivors and those with lower extremity amputations are at particular risk of low quality of life and life satisfaction, and may require additional attention in future earthquake rehabilitation programs.

    Intracorporeal orthotopic neobladder (iONB) creation following robotic radical cystectomy is an emerging procedure and robust functional data are required. To evaluate urodynamic features of iONB and bladder cancer-specific and general health-related quality-of-life (HRQOL) outcomes. We retrospectively assessed 28 men who underwent iONB creation (January 2012 to October 2013) and compared results to a previously characterized cohort of 79 of open ONB procedures. iONB pressure-volume properties were characterized using multichannel urodynamics (UDS). The Bladder Cancer Index (BCI) questionnaire, modified with mucus- and pad-related questions, and the Short Form Health Survey (SF-36) were used to evaluate urinary function and HRQOL. ONB cohorts were compared for functional outcomes and BCI score. Multivariable linear regression was used to assess predictors of BCI score. The median follow-up was 9.4 mo for the iONB and 62.1 mo for the open ONB group (pfunction (p=0.58) and urinary bother (p=0.31) were comparable between the groups. The surgical approach was not associated with the BCI score on multivariable analysis. Rates of 24-h pad use were comparable between iONB and open ONB groups (pad-free 17% vs. 19%; ≤2 pads 84% vs. 79%), as reflected by total pad usage (p=0.1); pad size and daytime wetness were worse in the iONB group. The clean intermittent catheterization rate was 10.7% in the iONB and 6.3% in the open ONB group. Limitations include the retrospective comparison, small number of patients and short follow-up for the iONB group. iONB had adequate UDS characteristics and comparable bladder cancer-specific HRQOL scores to open ONB. However, pad size and daytime wetness were worse for iONB, albeit over significantly shorter follow-up. We demonstrate that the volumetric and pressure characteristics are acceptable for a neobladder created using an entirely robot-assisted laparoscopic technique after bladder removal for cancer.

    Abstract Internet gaming disorder (IGD) contributes to poor quality of life (QOL) and cognitive dysfunction and is increasingly recognized as a social problem in various countries. However, no evidence exists to determine whether QOL and cognitive dysfunction stabilize after appropriate management. The present study addressed improvement in QOL and cognitive functioning associated with changes in addiction symptoms following outpatient management for IGD. A total of 84 young males (IGD group: N = 44, mean age: 19.159 ± 5.216 years; healthy control group: N = 40, mean age: 21.375 ± 6.307 years) participated in this study. We administered self-report questionnaires at baseline to assess clinical and psychological characteristics, and conducted traditional and computerized neuropsychological tests. Nineteen patients with IGD completed follow-up tests in the same manner after 6 months of outpatient treatment, which included pharmacotherapy with selective serotonin reuptake inhibitors. A baseline comparison of patients with IGD against the healthy control group showed that the IGD patients had more symptoms of depression and anxiety, higher degrees of impulsiveness and anger/aggression, higher levels of distress, poorer QOL, and impaired response inhibition. After 6 months of treatment, patients with IGD showed significant improvements in the severity of IGD, as well as in QOL, response inhibition, and executive functioning. Additionally, a stepwise multiple regression analysis revealed a favorable prognosis for IGD patients with low working memory functioning and high executive functioning at baseline. These results provide evidence regarding longitudinal changes in QOL and cognitive function following psychiatric intervention for IGD. Furthermore, it appears that response inhibition may be an objective state marker underlying the pathophysiology of IGD. PMID:27977620

    Depression and pain frequently occur together. The objective of this study was to investigate the effects of depression and pain on the impairment of daily functioning and quality of life (QOL) of depressed patients. We enrolled 131 acutely ill inpatients with major depressive disorder. Depression, pain, and daily functioning were assessed using the 17-item Hamilton Depression Rating Scale, the Short-Form 36 (SF-36) Body Pain Index, and the Work and Social Adjustment Scale. Health-related QOL was assessed using three primary domains of the SF-36: social functioning, vitality, and general health perceptions. Pearson׳s correlation and structural equation modeling were used to examine relationships among the study variables. Five models were proposed. In all, 129 patients completed all the measures. Model 5, both depression and pain impaired daily functioning and QOL, was the most fitted structural equation model (χ(2)=9.2, df=8, p=0.33, GFI=0.98, AGFI=0.94, TLI=0.99, CFI=0.99, RMSEA=0.03). The correlation between pain and depression was weak (r=-0.27, z=-2.95, p=0.003). This was a cross-sectional study with a small sample size. Depression and pain exert a direct influence on the impairment of daily functioning and QOL of depressed patients; this impairment could be expected regardless of increased pain, depression, or both pain and depression. Pain had a somewhat separate entity from depression. Copyright © 2014. Published by Elsevier B.V.

    To analyse in detail the relationship between the movement and generic health-related quality of life (HRQoL) indicators and the subjective feeling of health of the patients, as well as the objective movement parameters measured by the surgeon and the patient's opinion about the success of the total hip replacement (THR). We have only limited information about the effect of mobility function improvement on the HRQoL several years after THR. We have recently found that after THR postoperative health awareness is influenced mainly by cardiovascular diseases, but the effects of the movement parameters on the subsequent feelings of well-being were not examined. Retrospective longitudinal study. This study involved 109 patients who had had THR. The patients' health status and objective and subjective mobility function at the time of operation and five years later were evaluated using questionnaires (including EQ-5D and WOMAC scores) and the hospital database. All components of EQ-5D and WOMAC had significantly improved by Year 5 in patients who experienced a complete recovery after the operation, but not the mobility and pain components of EQ-5D for those patients who felt an improvement only in their subjective mobility function. The surgeon-assessed parameters and use of walking aids showed a similar distribution in patients who considered themselves to be healthy or only moderately sick five years after THR. Successful THR significantly improves the feeling of well-being and the mobility function of patients even five years after the operation. In individual cases, however, other subjective and objective factors, but not the mobility function, have a major influence on the HRQoL. Five years after successful THR, nursing care has to focus not only on the further improvement of the mobility but on strengthening the subjective feeling of the patient's well-being and health. © 2013 Blackwell Publishing Ltd.

    Endothelial function typically precedes clinical manifestations of cardiovascular disease and provides a potential mechanism for the associations observed between cardiovascular disease and sleep quality. This study examined how subjective and objective indicators of sleep quality relate to endothelial function, as measured by brachial artery flow-mediated dilation (FMD). In a clinical research centre, 100 non-shift working adults (mean age: 36 years) completed FMD testing and the Pittsburgh Sleep Quality Index, along with a polysomnography assessment to obtain the following measures: slow wave sleep, percentage rapid eye movement (REM) sleep, REM sleep latency, total arousal index, total sleep time, wake after sleep onset, sleep efficiency and apnea-hypopnea index. Bivariate correlations and follow-up multiple regressions examined how FMD related to subjective (i.e., Pittsburgh Sleep Quality Index scores) and objective (i.e., polysomnography-derived) indicators of sleep quality. After FMD showed bivariate correlations with Pittsburgh Sleep Quality Index scores, percentage REM sleep and REM latency, further examination with separate regression models indicated that these associations remained significant after adjustments for sex, age, race, hypertension, body mass index, apnea-hypopnea index, smoking and income (Ps Quality Index increased (indicating decreased subjective sleep quality) and percentage REM sleep decreased, while REM sleep latency increased (Ps quality and adverse changes in REM sleep were associated with diminished vasodilation, which could link sleep disturbances to cardiovascular disease.

    The Heinrichs-Carpenter Quality of Life Scale (QLS) is the most extensively used real-world community functioning scale in schizophrenia research. However, the extensive time required to administer it and the inclusion of items that overlap conceptually with negative symptoms limit its use across studies. The present study examined the validity and utility of two abbreviated QLS measures against the full QLS excluding negative symptom items. The sample included 1427 patients with schizophrenia who completed the baseline visit in the CATIE study. The validity of two abbreviated QLS measures (7-item and 4-item) were examined with the full QLS, excluding the intrapsychic foundations subscale, using correlation analysis. The utility of the abbreviated measures was explored by examining associations between the functioning scales and clinical variables and longitudinal change. Both abbreviated QLS measures were highly predictive of the full QLS (both r=0.91, pschizophrenia, especially when assessment of functional outcome is not the focus. Copyright © 2014 Elsevier B.V.

    Speech disturbances in schizophrenia impact on the individual's communicative ability. Although they are considered a core feature of schizophrenia, comparatively little work has been done to examine their impact on the life experiences of patients. This study aimed to examine the relationship between schizophrenia speech disturbances, including those traditionally known as formal thought disorder (TD), and quality of life (QoL). It assessed effects on functioning (objective QoL) and satisfaction (subjective QoL) concurrently, while controlling for the influence of neurocognition and depression. Fifty-four patients with schizophrenia/schizoaffective disorder were administered the MATRICS Consensus Cognitive Battery (MCCB), the PANSS, MADRS (with separate ratings for negative TD [verbal underproductivity] and positive TD [verbal disorganisation and pressured speech]) and Lehman's QOLI assessing both objective and subjective QoL. Ratings of positive and negative TD, depression, and general neurocognition were entered into hierarchical regressions to explore their relationship with both life functioning and satisfaction. Verbal underproductivity was a significant predictor of objective QoL, while pressured speech had a trend association with subjective QoL. This suggests a differential relationship between speech disturbances and QoL. Verbal underproductivity seems to affect daily functioning and relations with others, while pressured speech is predictive of satisfaction with life. The impact of verbal underproductivity on QoL suggests it to be an important target for rehabilitation in schizophrenia. Copyright © 2014 Elsevier Inc. All rights reserved.

  8. Maximum likelihood cost functions for neural network models of air quality data

    Dorling, Stephen R.; Foxall, Robert J.; Mandic, Danilo P.; Cawley, Gavin C.

    The prediction of episodes of poor air quality using artificial neural networks is investigated, concentrating on selection of the most appropriate cost function used in training. Different cost functions correspond to different distributional assumptions regarding the data, the appropriate choice depends on whether a forecast of absolute pollutant concentration or prediction of exceedence events is of principle importance. The cost functions investigated correspond to logistic regression, homoscedastic Gaussian (i.e. conventional sum-of-squares) regression and heteroscedastic Gaussian regression. Both linear and nonlinear neural network architectures are evaluated. While the results presented relate to a dataset describing the daily time-series of the concentration of surface level ozone (O 3) in urban Berlin, the methods applied are quite general and applicable to a wide range of pollutants and locations. The heteroscedastic Gaussian regression model outperforms the other nonlinear methods investigated; however, there is little improvement resulting from the use of nonlinear rather than linear models. Of greater significance is the flexibility afforded by the nonlinear heteroscedastic Gaussian regression model for a range of potential end-users, who may all have different answers to the question: "What is more important, correctly predicting exceedences or avoiding false alarms?".

    Amla (Indian gooseberry) and its processed products are rich source of vitamin C, phenols, dietary fibre and antioxidants. In contrast, ice cream is a poor source of these phytochemicals and antioxidants; therefore, the present investigation was undertaken to enhance the functional properties and nutritional quality of ice cream with the incorporation of processed amla. Ice cream was prepared using amla shreds, pulp, preserve and candy at 5 to 20 % and powder at 0.5 to 2.0 % levels in ice cream mix prior to freezing. Inclusion of amla products at augmented levels resulted in significant changes in physico-chemical properties and phytochemical content of ice cream. The total solids decreased on addition of shreds and pulp and increased with preserve, candy and powder in ice cream at increasing levels. The functional constituents i.e. fibre, total phenols, tannins, ascorbic acid and antioxidant activity increased with greater level of inclusion. Incorporation of processed amla raised the melting resistance of ice cream and decreased the overrun. The samples with 5 % shreds and pulp, 10 % preserve and candy and 0.5 % powder were found to have highest overall acceptability scores. Inclusion of amla in all the forms i.e. shreds, pulp, preserve, candy and powder enhanced the functional properties and nutritional value of ice cream.

    Full Text Available The functional assessment of multiple sclerosis (FAMS is a disease-specific instrument that describes functional status of individuals with multiple sclerosis. The instrument was originally developed in the US and has been adapted to different languages including Danish. This study is a validation of the Danish version of FAMS in a sample of individuals referred to a four-week rehabilitation program at either of the two Multiple Sclerosis Rehabilitation centers in Denmark. FAMS data were obtained through self-completed questionnaires from 190 individuals who attended the rehabilitation centers after referral by their general practitioner or specialist neurologist. The validation of the FAMS included assessment of data quality, scale assumptions, acceptability, construct validity, and reliability. Responsiveness was assessed by comparing individual FAMS scores at admission with the discharge score for groups of respondents who reported no change, improvement, or deterioration in their ability to cope with their illness. The Danish version of FAMS appears to be an acceptable, valid, and reliable measure of current health and functional status of individuals with multiple sclerosis.

    The objective was to evaluate the relationship among oral habits, oral function and oral health-related quality of life (OHRQoL) in children. Three hundred and twenty-eight subjects (8-14 years old) were assessed for orofacial function using the Brazilian version of the Nordic Orofacial Test-Screening (NOT-S). OHRQoL was assessed using the Child Perceptions Questionnaires (Brazilian versions) for the 8-10 (CPQ(8-10)) and 11-14 (CPQ(11-14)) year age groups. The subjects were distributed into a Habit group and a Habit-free group according to domain III (Habits) of the NOT-S. Oral habits were present in 71.3% of the sample (p = .0001), with a higher prevalence in females (62.8%, p = .001). The NOT-S, CPQ(8-10) and CPQ(11-14) scores were higher in the Habit group (P = .0001, P = .009 and p = .001, respectively). Domain I (Sensory Function) was significantly more affected in Habit group subjects (p = .001). The NOT-S scores were positively correlated with the CPQ(8-10) and CPQ(11-14) scores only in the Habit group (r = .32, p = .0003 and r = .30, p = .001, respectively). These results indicate that oral habits can impact OHRQoL. Moreover, orofacial dysfunctions were associated with worse OHRQoL in subjects with oral habits.

    Patients who have limb amputation for musculoskeletal tumours are a rare group of cancer survivors. This was a prospective cross-sectional survey of patients from five specialist centres for sarcoma surgery in England. Physical function, pain and quality of life (QOL) outcomes were collected after lower extremity amputation for bone or soft-tissue tumours to evaluate the survivorship experience and inform service provision. Of 250 patients, 105 (42%) responded between September 2012 and June 2013. From these, completed questionnaires were received from 100 patients with a mean age of 53.6 years (19 to 91). In total 60 (62%) were male and 37 (38%) were female (three not specified). The diagnosis was primary bone sarcoma in 63 and soft-tissue tumour in 37. A total of 20 tumours were located in the hip or pelvis, 31 above the knee, 32 between the knee and ankle and 17 in the ankle or foot. In total 22 had hemipelvectomy, nine hip disarticulation, 35 transfemoral amputation, one knee disarticulation, 30 transtibial amputation, two toe amputations and one rotationplasty. The Toronto Extremity Salvage Score (TESS) differed by amputation level, with poorer scores at higher levels (p amputation level is linked to physical function, but not QOL or pain measures. Pain and physical function significantly impact on QOL. These results are helpful in managing the expectations of patients about treatment and addressing their complex needs. ©2015 The British Editorial Society of Bone & Joint Surgery.

    The term explosive detection system (EDS) is used by the TSA to describe equipment that is certified to detect explosives in checked bags. The EDS, as certified, by the TSL must consist of device for interrogating a bag and an automated detection algorithm (ATD) for evaluating the results of the interrogation. We only consider CT as the interrogation device in this report. A schematic drawing of a CT-based EDS is shown in Figure 2. The output of the ATD is the binary decision of alarm or non-alarm. Alarms may true- or false-positives. Non-alarms may be true- or false-negatives. False positives are also denoted false alarms. The true detection means that the ATD reports an alarm when a threat is present in the scanned bag. The probability of detecting a threat given that a threat is present is denoted the probability of detection (PD). The probability of false alarm (PFA) is the case when an alarm is reported when a threat is not present in a bag. Certification in this context means passing tests for PD and PFA at the TSL. The results of the EDS include CT cross-sectional images of the bag and specifics about the alarmed objects generated by ATD. These results are presented on a display so that a person may override the decision of ATD and declare the alarm to be a non-alarm. This process is denoted clearing. Bags that are not cleared by the person are sent to a secondary inspection process. Here the bags may be opened or assessed with explosive trace detection (ETD) in order to clear the bags. Bags that are not cleared at this point are evaluated by an ordinance disposal team. The CT scanner along with ATD is denoted Level 1 screening. The process of clearing on a display is denoted Level 2 screening. Secondary inspection is denoted Level 3 screening. Vendors of the deployed EDSs supply the TSA with equipment for all three levels. Therefore, the term EDS may include the equipment provided for Levels 1, 2 and 3. A schematic diagram of an EDS and the levels of

    A deployable M-braced truss structure, efficiently packaged into a compact stowed position and expandable to an operative position at the use site is described. The M-braced configuration effectively separates tension compression and shear in the structure and permits efficient structural design. Both diagonals and longerons telescope from an M-braced base unit and deploy either pneumatically, mechanically by springs or cables, or by powered reciprocating mechanisms. Upon full deployment, the diagonals and longerons lock into place with a simple latch mechanism.

    Consider a rigid-flexible coupled system which consists of a central rigid body deploying a flexible appendage,The appendage is modeled as a finite deflection beam having linear constitutive equations.By taking the energy integral as Lyapunov function,it is proved that nonlinear transverse vibrations of the beam undergoing uniform extension or retrieval are stable when there are not controlling moment in the central rigid body and driving force on the beam,according to the partial stablity theorem.

    It is vital to forecast gas and particle matter concentrations and emission rates (GPCER) from livestock production facilities to assess the impact of airborne pollutants on human health, ecological environment, and global warming. Modeling source air quality is a complex process because of abundant nonlinear interactions between GPCER and other factors. The objective of this study was to introduce statistical methods and radial basis function (RBF) neural network to predict daily source air quality in Iowa swine deep-pit finishing buildings. The results show that four variables (outdoor and indoor temperature, animal units, and ventilation rates) were identified as relative important model inputs using statistical methods. It can be further demonstrated that only two factors, the environment factor and the animal factor, were capable of explaining more than 94% of the total variability after performing principal component analysis. The introduction of fewer uncorrelated variables to the neural network would result in the reduction of the model structure complexity, minimize computation cost, and eliminate model overfitting problems. The obtained results of RBF network prediction were in good agreement with the actual measurements, with values of the correlation coefficient between 0.741 and 0.995 and very low values of systemic performance indexes for all the models. The good results indicated the RBF network could be trained to model these highly nonlinear relationships. Thus, the RBF neural network technology combined with multivariate statistical methods is a promising tool for air pollutant emissions modeling.

    To determine if Functional Electrical Stimulation (FES) would improve ischemic pain, walking distance, and quality of life of patients with intermittent claudication. Single blind, randomized block, two factorial design. Patients diagnosed with Peripheral Artery Disease (PAD) and intermittent claudication (IC). Ankle Brachial Index ranged 0.4-0.9 on at least one leg. Patients were randomly assigned to experimental (FES+Walk, N=13) or control (WALK, N=14) groups. Experimental group patients received FES to the dorsiflexor and plantarflexor muscles while walking for 1h/day, six days/week for eight weeks. Control group patients received similar intervention without FES. A Follow-up period of both groups lasted eight weeks. Outcome measures were taken at baseline (T0), after intervention (T1), and after follow-up (T2). Primary measures included Perceived Pain Intensity (PPI), Six minute walk (6MW), and Peripheral Arterial Disease Quality of Life (PADQOL). Secondary measures included Intermittent Claudication Questionnaire (ICQ) and Timed Up and Go (TUG). Group by time interactions in PPI were significant (Phttps://projectreporter.nih.gov/project_info_description.cfm?aid=8748641&icde=30695377&ddparam=&ddvalue=&ddsub=&cr=1&csb=default&cs=ASC. https://clinicaltrials.gov/ct2/show/NCT02384980?term=David+Embrey&rank=1.

    Ciliated protozoa play important roles in micro-ecosystems, especially in marine biotopes. However, few studies have been carried out on the periphytic, or aufwuch, forms in mariculture waters so far. In this study, we sampled periphytic ciliate communities in two closed mariculture ponds (ponds CP1 and CP2) and a natural seawater reservoir (pond RP) using a glass slide method to evaluate their colonizing processes and general ecological features, as well as their application as water quality indicators. We analyzed species compositions, structural parameters (species number, richness, diversity, evenness, abundance and d BP) and functional parameters ( G, S eq and T 90%). Pond RP was characterized by higher levels of structural parameters (except for abundance and d BP) and more equal proportion of the major taxonomic groups. The values of S eq were significantly higher in pond RP and similar in both pond CP1 and CP2. It was also demonstrated that environmental factors, including NO2-H, NO3-H, NH3-H, soluble reactive phosphate, temperature and pH, were the first principal factors affecting the communities. Among them, temperature and chemical factors were all significantly and negatively correlated with species number ( Pquality. Results of this study confirmed the periphytic ciliate communities to be useful bioindicators of water quality in intensive mariculture waters.

    The physiology of oocyte in vitro maturation remains elusive. Generally, the oocytes have a very low maturation rate under in vitro conditions. In the current study, we found that melatonin promotes the maturation of oocytes in which mitochondria play a pivotal role. It was identified that; (1) mitochondria are the major sites for melatonin synthesis in oocytes and they synthesize large amounts of melatonin during their maturation; (2) melatonin improves mitochondrial function by increased mtDNA copy, mitochondrial membrane potential (ΔΨm) and mitochondrial distribution and ATP production in oocytes; (3) the meiotic spindle assembly is enhanced; (4) melatonin reduces ROS production and inhibits 8-oxodG formation, thereby protecting potential DNA mutation from oxidative damage. As a result, melatonin improves the quality of oocytes, significantly accelerates the developmental ability of IVF embryo. The results provide novel knowledge on the physiology of oocyte's maturation, especially under in vitro conditions.
