  5. Environments for ageing, assistive technology and self-determination: ethical perspectives. (United States)

    Remmers, Hartmut


    The development of information and communication technologies for design of environments for ageing is of great importance considering demographic trends in the future. There is a realistic hope for the preservation of self-determination and independence in the long term. However, some risks like a gradual loss of privacy should not be underestimated. The article discusses some ethical problems within this context. At the same time, the article demonstrates that the development and implementation of these technologies might be discussed for instance under some ethical assumptions of personal self-responsibility as well as social responsibility for the widest independence in advanced age.

    Full Text Available The energy policies of today focus mainly on sustainable energy systems and renewable energy resources. Chemistry is closely related to energy recycling, energy types, renewable energy, and nature-energy interaction; therefore, it is now an obligation to enrich chemistry classes with renewable energy concepts and related awareness. Before creating renewable energy awareness, the factors thought to affect such awareness should be determined. Knowing these factors would facilitate finding out what to take into account in creating renewable energy awareness. In this study, certain factors thought to affect the development of renewable energy awareness were investigated. The awareness was created through a technology-assisted renewable energy module and assessed using a renewable energy assessment tool. The effects of the students’ self-directed learning readiness with Guglielmino (1977, inner-individual orientation, and anxiety orientation on the awareness were examined. These three factors were found to have significant effects on renewable energy, which was developed through technology utilization. In addition, based on the finding that delivering the subject of renewable energy in technology assisted environments is more effective, the criteria that should be taken into consideration in transforming this subject into a design model that is more suitable for distance education were identified.

  10. The use of mobile devices as assistive technology in resource-limited environments: access for learners with visual impairments in Kenya. (United States)

    Foley, Alan R; Masingila, Joanna O


    In this paper, the authors explore the use of mobile devices as assistive technology for students with visual impairments in resource-limited environments. This paper provides initial data and analysis from an ongoing project in Kenya using tablet devices to provide access to education and independence for university students with visual impairments in Kenya. The project is a design-based research project in which we have developed and are refining a theoretically grounded intervention--a model for developing communities of practice to support the use of mobile technology as an assistive technology. We are collecting data to assess the efficacy and improve the model as well as inform the literature that has guided the design of the intervention. In examining the impact of the use of mobile devices for the students with visual impairments, we found that the devices provide the students with (a) access to education, (b) the means to participate in everyday life and (c) the opportunity to create a community of practice. Findings from this project suggest that communities of practice are both a viable and a valuable approach for facilitating the diffusion and support of mobile devices as assistive technology for students with visual impairments in resource-limited environments. Implications for Rehabilitation The use of mobile devices as assistive technology in resource-limited environments provides students with visual impairments access to education and enhanced means to participate in everyday life. Communities of practice are both a viable and a valuable approach for facilitating the diffusion and support of mobile devices as assistive technology for students with visual impairments in resource-limited environments. Providing access to assistive technology early and consistently throughout students' schooling builds both their skill and confidence and also demonstrates the capabilities of people with visual impairments to the larger society.

  16. Technology-assisted psychoanalysis. (United States)

    Scharff, Jill Savege


    Teleanalysis-remote psychoanalysis by telephone, voice over internet protocol (VoIP), or videoteleconference (VTC)-has been thought of as a distortion of the frame that cannot support authentic analytic process. Yet it can augment continuity, permit optimum frequency of analytic sessions for in-depth analytic work, and enable outreach to analysands in areas far from specialized psychoanalytic centers. Theoretical arguments against teleanalysis are presented and countered and its advantages and disadvantages discussed. Vignettes of analytic process from teleanalytic sessions are presented, and indications, contraindications, and ethical concerns are addressed. The aim is to provide material from which to judge the authenticity of analytic process supported by technology.

  20. Effects of the use of assisted reproductive technologies and an obesogenic environment on resistance artery function and diabetes biomarkers in mice offspring.

    Directory of Open Access Journals (Sweden)

    Francisco I Ramirez-Perez

    Full Text Available Maternal obesity affects the incidence of cardiovascular disease and diabetes in offspring. Also the use of assisted reproductive technologies (ART has been associated with cardiovascular deficiencies in offspring. Obese women often suffer from infertility and use ART to achieve a pregnancy, but the combined effects of maternal obesity and ART on cardiovascular health and incidence of diabetes in the offspring is not known. Here, we report the effects of the use of ART within an obesogenic environment, consisting of feeding a western diet (WD to dams and offspring, on resistance artery function and presence of diabetes biomarkers in juvenile mice offspring. Our results indicate that WD and ART interacted to induce endothelial dysfunction in mesenteric resistance arteries isolated from 7-week-old mice offspring. This was determined by presence of a reduced acetylcholine-induced dilation compared to controls. The arteries from these WD-ART mice also had greater wall cross-sectional areas and wall to lumen ratios indicative of vascular hypertrophic remodeling. Of the diabetes biomarkers measured, only resistin was affected by a WD×ART interaction. Serum resistin was significantly greater in WD-ART offspring compared to controls. Diet and sex effects were observed in other diabetes biomarkers. Our conclusion is that in mice the use of ART within an obesogenic environment interacts to favor the development of endothelial dysfunction in the resistance arteries of juvenile offspring, while having marginal effects on diabetes biomarkers.

  2. Mobile assistive technologies for the visually impaired. (United States)

    Hakobyan, Lilit; Lumsden, Jo; O'Sullivan, Dympna; Bartlett, Hannah


    There are around 285 million visually impaired people worldwide, and around 370,000 people are registered as blind or partially sighted in the UK. Ongoing advances in information technology (IT) are increasing the scope for IT-based mobile assistive technologies to facilitate the independence, safety, and improved quality of life of the visually impaired. Research is being directed at making mobile phones and other handheld devices accessible via our haptic (touch) and audio sensory channels. We review research and innovation within the field of mobile assistive technology for the visually impaired and, in so doing, highlight the need for successful collaboration between clinical expertise, computer science, and domain users to realize fully the potential benefits of such technologies. We initially reflect on research that has been conducted to make mobile phones more accessible to people with vision loss. We then discuss innovative assistive applications designed for the visually impaired that are either delivered via mainstream devices and can be used while in motion (e.g., mobile phones) or are embedded within an environment that may be in motion (e.g., public transport) or within which the user may be in motion (e.g., smart homes).

  3. [Evolution of assisted reproductive technologies]. (United States)

    Jouannet, Pierre


    When natural conception is impossible and the underlying problem cannot be treated, medical intervention can reproduce the steps necessary for fertilization and early embryo development. The first known medical action in the field of human reproduction took place at the end of the 18th century, in the form of artificial insemination with the husband's semen, thus dissociating sexual intercourse from procreation. A further upheaval occurred at the end of the 19th century, with the use of donor sperm, separating the notions of genetic descent and parenthood. In the second half of the 20th century, medically assisted procreation saw two major technological advances, namely gamete freezing and in vitro fertilization (IVF). The first child conceived with frozen-thawed sperm was born in 1953, and the first IVF baby in 1978. Fertilization by intracytoplasmic sperm injection (ICSI), first developed in 1992, can overcome many causes of male infertility. The convergence of reproductive biology and genetics has now opened up the possibility of screening for chromosome and gene defects in the embryo, prior to implantation. Thus, assisted reproductive technologies (ART) not only serve as a substitute for natural conception but can also avoid the birth of a disabled child While new technologies continue to extend the available options for infertile couples, they also have the potential to help single women and homosexual couples to have children. These practices are currently only accepted in certain countries. Overall, these new medical technologies have contributed to changing our conception of human reproduction, opening up new paradigms of parenthood and raising new challenges for society.

  7. Substitution of Assisted Living Services by Assistive Technology - Experts Opinions and Technical Feasibility. (United States)

    Schwartze, Jonas; Prekazi, Arianit; Schrom, Harald; Marschollek, Michael


    Ambient assisted living (AAL) may support ageing in place but is primarily driven by technology. The aim of this work is, to identifying reasons to move into assisted living institutions, their range of service and possible substitutability. We did semi-structured interviews with five experts from assisted living institutions and used results to design and implement assistive technologies in an AAL environment using BASIS, a cross domain bus system for smart buildings. Reasons for moving to assisted living institutions are expected benefits for chronic health problems, safety, social isolation and carefree living. We implemented six application systems for inactivity monitoring, stove shutdown, air quality monitoring, medication and appointment reminders, detection of unwanted situations before leaving and optical ringing of the doorbell. Substitution of selected assisted living services is feasible and has potential to delay necessity to move into assisted living institution if complement social services are installed.

  14. Performance Evaluation Methods for Assistive Robotic Technology (United States)

    Tsui, Katherine M.; Feil-Seifer, David J.; Matarić, Maja J.; Yanco, Holly A.

    Robots have been developed for several assistive technology domains, including intervention for Autism Spectrum Disorders, eldercare, and post-stroke rehabilitation. Assistive robots have also been used to promote independent living through the use of devices such as intelligent wheelchairs, assistive robotic arms, and external limb prostheses. Work in the broad field of assistive robotic technology can be divided into two major research phases: technology development, in which new devices, software, and interfaces are created; and clinical, in which assistive technology is applied to a given end-user population. Moving from technology development towards clinical applications is a significant challenge. Developing performance metrics for assistive robots poses a related set of challenges. In this paper, we survey several areas of assistive robotic technology in order to derive and demonstrate domain-specific means for evaluating the performance of such systems. We also present two case studies of applied performance measures and a discussion regarding the ubiquity of functional performance measures across the sampled domains. Finally, we present guidelines for incorporating human performance metrics into end-user evaluations of assistive robotic technologies.

    International Nuclear Information System (INIS)

    Dawes, W.R. Jr.


    The complete radiation environment of neutrons, total dose, transient ionizing radiation, and energetic cosmic rays (SEU) can have various deleterious effects upon semiconductor electronic components. However, hardening techniques for these radiation effects have been developed for the various semiconduct technologies that will permit their use even in severe radiation environments. The process techniques are occasionally line dependent and may require modification to achieve the desired hardness goal. Similarly, hardening semiconductor components for elevated thermal operation can be achieved with process techniques which, unlike the radiation case, are readily transferable between process lines. Radiation effects and hardening technologies are discussed for Metal Oxide Semiconductor (MOS), Bipolar, Junction Field Effect Transistors (JFET), Metal Semiconductor Field Effect Transistor (MESFET), Diode, Electro-optic, and crystal technologies. 44 refs., 44 figs

  20. Assistive Technology for Individuals with Special Seeds

    Directory of Open Access Journals (Sweden)

    Adrian Lupasc


    Full Text Available Disabled people face barriers in performing their various activities, including teaching. By using assistive technologies for different activities, people with disabilities may be able to perform a wider range of tasks independently. Fortunately, it helps to reduce many of these barriers, but, unfortunately, disabled people (learning, autism or ADHD face a variety of barriers when they want to use software tools or hardware devices. In this regard, assistive technologies are available to help persons with different types of disabilities, from cognitive problems to physical impairment. Hardware devices and software tools (known as adaptive or assistive technologies have been developed to provide functional alternatives for all individuals with disabilities, depending on the type of disability. In addition, the use of assistive technologies to support them is an effective approach for many persons with disabilities, regardless of the type of disability. Additionally, individuals with disabilities often experience greater success when they are allowed to use their abilities to work around their disabilities (the challenges they imply. Moreover, mobile devices are useful for their ability to weave Internet access and social networking into the daily life. To the people with disabilities, these devices have the potential to unlock unprecedented new possibilities for communication or navigation. In this context, some actual assistive technology and approaches to use them are described in this paper.

  1. Reducing multiple births in assisted reproduction technology. (United States)

    Bhattacharya, Siladitya; Kamath, Mohan S


    Multiple pregnancy, a complication of assisted reproduction technology, is associated with poorer maternal and perinatal outcomes. The primary reason behind this is the strategy of replacing more than one embryo during an assisted reproduction technology cycle to maximise pregnancy rates. The solution to this problem is to reduce the number of embryos transferred during in-vitro fertilisation. The transition from triple- to double-embryo transfer, which decreased the risk of triplets without compromising pregnancy rates, was easily implemented. The adoption of a single embryo transfer policy has been slow because of concerns about impaired pregnancy rates in a fresh assisted reproduction technology cycle. Widespread availability of effective cryopreservation programmes means that elective single embryo transfer, along with subsequent frozen embryo transfers, could provide a way forward. Any such strategy will need to consider couples' preferences and existing funding policies, both of which have a profound influence on decision making around embryo transfer.

  4. Technology-assisted dietary assessment (United States)

    Zhu, Fengqing; Mariappan, Anand; Boushey, Carol J.; Kerr, Deb; Lutes, Kyle D.; Ebert, David S.; Delp, Edward J.


    Dietary intake provides valuable insights for mounting intervention programs for prevention of disease. With growing concern for adolescent obesity, the need to accurately measure diet becomes imperative. Assessment among adolescents is problematic as this group has irregular eating patterns and have less enthusiasm for recording food intake. Preliminary studies among adolescents suggest that innovative use of technology may improve the accuracy of diet information from young people. In this paper, we propose a novel food record method using a mobile device that will provide an accurate account of daily food and nutrient intake among adolescents. Our approach includes the use of image analysis tools for identification and quantification of food consumption. Images obtained before and after food is consumed can be used to estimate the diet of an individual. In this paper we describe our initial results and indicate the potential of the proposed system.

  13. Volatile Environments with Virtualisation Technologies

    CERN Multimedia

    CERN. Geneva


    Sometimes our job or even our interest to learn something new, requires from us to install a lot of different software to allow a specific program to run on our operating system. This (in the best case) might just prohibit your program to run due to conflicts between different library or language versions; in the worst case your operating system will start becoming full of junk and later on will be slow and insecure. In this course we will explore two relatively new but very well established virtualisation technologies: Vagrant and Docker and how those tools can help us to keep a tidy, exportable and transferable developing environment on our home or work computer.

    Okamura, Tetsuya; Murakami, Tohru; Agematsu, Takashi; Okumura, Susumu; Arakawa, Kazuo.


    A computer-based operation system for a cyclotron which assists inexperienced operators has been developed. Cyclotron start-up operations require dozens of adjustable parameters to be finely tuned to maximize extracted beam current. The human interfaces of the system provide a visual environment designed to enhance beam parameter adjustments. First, the mental model of operators is analyzed. It is supposed to be composed of five partial mental models: beam behavior model, feasible setting regions model, parameter sensitivity model, parameter mutual relation model, and status map model. Next, based on these models, three visual interfaces are developed, i.e., (1) Beam trajectory is rapidly calculated and graphically displayed whenever the operators change the cyclotron parameters. (2) Feasible setting regions (FSR) of the parameters that satisfy the cyclotron's beam acceptance criteria are indicated. (3) Search traces, being a historical visual map of beam current values, are superimposed on the FSRs. Finally, to evaluate system effectiveness, the search time required to reach maximum beam current conditions was measured. In addition, system operability was evaluated using written questionnaires. Results of the experiment showed that the search time to reach specific beam conditions was reduced by approximately 65% using these interfaces. The written questionnaires survey showed the operators highly evaluate system operability. (author)

  17. Environmentally assisted cracking mechanisms in repository environments

    International Nuclear Information System (INIS)

    Mills, W.J.


    This paper assesses how environmentally assisted cracking (EAC) mechanisms in candidate container materials can be identified to enhance the accuracy of long-term projections of performance in the repository. In low and intermediate strength steels, the role of the two principal mechanisms, slip dissolution/film rupture (SD/FR) and hydrogen embrittlement (HE), is a very complex and controversial issue. No unanimity exists concerning the operative cracking mechanisms, and there is no unique or rigorous approach that would be persuasive in selecting an appropriate model. Both of the proposed mechanisms have common rate controlling processes such as surface adsorption rate, passivation rate, and oxidation rupture rate, which makes it difficult to identify the operative mechanism. Development of a quantitative model for predicting environmental effects for low-carbon steels in repository environments would provide a theoretical basis for assuring the long-term structural integrity of waste-package containment. To date, only one quantitative model has been developed. The agreement between predicted and observed behavior suggests that SD/FR processes control the environmental acceleration in crack growth rates for this class of materials. Deviations from predicted behavior due to HE effects should be uncovered experimentally. 59 refs., 4 figs., 4 tabs

  18. Technology, energy and the environment (United States)

    Mitchell, Glenn Terry

    This dissertation consists of three distinct papers concerned with technology, energy and the environment. The first paper is an empirical analysis of production under uncertainty, using agricultural production data from the central United States. Unlike previous work, this analysis identifies the effect of actual realizations of weather as well as farmers' expectations about weather. The results indicate that both of these are significant factors explaining short run profits in agriculture. Expectations about weather, called climate, affect production choices, and actual weather affects realized output. These results provide better understanding of the effect of climate change in agriculture. The second paper examines how emissions taxes induce innovation that reduces pollution. A polluting firm chooses technical improvement to minimize cost over an infinite horizon, given an emission tax set by a planner. This leads to a solution path for technical change. Changes in the tax rate affect the path for innovation. Setting the tax at equal to the marginal damage (which is optimal in a static setting with no technical change) is not optimal in the presence of technical change. When abatement is also available as an alternative to technical change, changes in the tax can have mixed effects, due to substitution effects. The third paper extends the theoretical framework for exploring the diffusion of new technologies. Information about new technologies spreads through the economy by means of a network. The pattern of diffusion will depend on the structure of this network. Observed networks are the result of an evolutionary process. This paper identifies how these evolutionary outcomes compare with optimal solutions. The conditions guaranteeing convergence to an optimal outcome are quite stringent. It is useful to determine the set of initial population states that do converge to an optimal outcome. The distribution of costs and benefits among the agents within an

  20. Assistive technology for memory support in dementia. (United States)

    Van der Roest, Henriëtte G; Wenborn, Jennifer; Pastink, Channah; Dröes, Rose-Marie; Orrell, Martin


    The sustained interest in electronic assistive technology in dementia care has been fuelled by the urgent need to develop useful approaches to help support people with dementia at home. Also the low costs and wide availability of electronic devices make it more feasible to use electronic devices for the benefit of disabled persons. Information Communication Technology (ICT) devices designed to support people with dementia are usually referred to as Assistive Technology (AT) or Electronic Assistive Technology (EAT). By using AT in this review we refer to electronic assistive devices. A range of AT devices has been developed to support people with dementia and their carers to manage their daily activities and to enhance safety, for example electronic pill boxes, picture phones, or mobile tracking devices. Many are commercially available. However, the usefulness and user-friendliness of these devices are often poorly evaluated. Although reviews of (electronic) memory aids do exist, a systematic review of studies focusing on the efficacy of AT for memory support in people with dementia is lacking. Such a review would guide people with dementia and their informal and professional carers in selecting appropriate AT devices. Primary objectiveTo assess the efficacy of AT for memory support in people with dementia in terms of daily performance of personal and instrumental activities of daily living (ADL), level of dependency, and admission to long-term care. Secondary objectiveTo assess the impact of AT on: users (autonomy, usefulness and user-friendliness, adoption of AT); cognitive function and neuropsychiatric symptoms; need for informal and formal care; perceived quality of life; informal carer burden, self-esteem and feelings of competence; formal carer work satisfaction, workload and feelings of competence; and adverse events.

  3. UGV technology for urban environments (United States)

    Christensen, Henrik I.; Folkeson, John; Hedstrom, Andreas; Lundberg, Carl


    Deployment of humans in an urban setting for search and rescue type missions poses a major risk to the personnel. In rescue missions the risk can stem from debris, gas, etc. and in a strategic setting the risk can stem from snipers, mines, gas, etc. There is consequently a natural interest in studies of how UGV technology can be deployed for tasks such as reconnaissance, retrieval of objects (bombs, injured people, etc.). Today most vehicles used by the military and bomb squads are tele-operated and without any autonomony. This implies that operation of the vehicles is a stressful and demanding task. Part of this stress can be removed through introduction of autonomous functionality. Autonomy implicitly requires use of map information to allow the system to localize and traverse a particular area in addition autonomous mapping of an area is a valuable functionality as part of reconnaissance missions to provide an initial inventory of a new area. A host of different sensory modalities can be used for mapping. In general no single modality is, however, sufficient for robust and efficient mapping. In the present study GPS, Inertial Cues, Laser ranging and Odometry is used for simultaneous mapping and localization in urban environments. The mapping is carried out autonomously using a coverage strategy to ensure full mapping of a particular area. In relation to mapping another important issue is the design of an efficient user interface that allows a regular rescue worker, or a soldier, to operate the vehicle without detailed knowledge about robotics. A number of different designs for user interfaces will be presented and results from studies with a range of end-users (soldiers) will also be reported. The complete system has been tested in an urban warfare facility outside of Stockholm. Detailed results will be reposted from two different test facilities.

  7. Assisted reproductive technology: Islamic Sunni perspective. (United States)

    Chamsi-Pasha, Hassan; Albar, Mohammed Ali


    Islam acknowledges that infertility is a significant hardship. Attempts to cure infertility are not only permissible, but also encouraged in Islam. Over the last three decades, a multitude of advances in assisted reproductive technologies (ARTs) have appeared. This review was carried out to inform readers, who are not familiar with Islamic doctrine, about the Sunni perspective on this topic. Systematic review of the literature. A series of searches was conducted of Medline databases published in English between January 1978 and December 2013 with the following assisted reproduction, infertility, gender selection, ethics, bioethics, and Islam. In Islamic Sunni law, all ARTs are allowed, provided that the source of the sperm, ovum, and uterus comes from a legally married couple during the span of their marriage. All forms of surrogacy are forbidden. A third-party donor is not allowed, whether he or she is providing sperm, eggs, embryos, or a uterus. Frozen preimplantation may be transferred to the wife in a successive cycle provided the marital bondage is not absolved by death or divorce. Gender selection for medical reasons is permitted. It is allowed for limited social reasons by some jurists, provided it does not involve discrimination against either sex. ART is acceptable and commendable in Islamic Sunni law provided it is practiced within the husband and wife dyad during the span of their marital contract. No third party should intrude upon the marital function of procreation. Surrogacy is not accepted by Sunni Islamic authorities.

  8. Cancer in women after assisted reproductive technology. (United States)

    Luke, Barbara; Brown, Morton B; Spector, Logan G; Missmer, Stacey A; Leach, Richard E; Williams, Melanie; Koch, Lori; Smith, Yolanda; Stern, Judy E; Ball, G David; Schymura, Maria J


    To evaluate the risk of cancer after assisted reproductive technology (ART) therapy. Longitudinal cohort study. Not applicable. New York, Texas, and Illinois residents between 2004 and 2009, treated with ART, comprising cycles of 113,226 women, including 53,859 women without prior ART treatment, who were linked to their respective state cancer registries and whose cycles were reported to the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System (SART CORS). None. Diagnosis of cancer, as reported to the state cancer registry; standardized incidence ratios (SIR) and their 95% confidence intervals, comparing the observed to expected cancer cases based on age-specific cancer rates in the general population of each state. Among the cohort of women without prior ART therapy, hazard ratios (HR) and 95% confidence intervals (CI) were calculated for treatment parameters and reproductive history factors. The mean follow-up period was 4.87 years; among women without prior ART, 450 women developed 460 cancers. Women treated with ART had a statistically significantly lower risk for all cancers (for all women: SIR 0.78; CI, 0.73-0.83; women without prior ART: SIR 0.75; CI, 0.68-0.82), breast cancer, and all female genital cancers; a non-statistically-significant lower risk for endocrine and uterine cancer; and a non-statistically-significant higher risk for melanoma and ovarian cancer. Among women without prior ART, we found no statistically significant increased HR by parity, number of cycles, cumulative follicle-stimulating hormone dosage, or cycle outcome. Women initiating ART treatment have no greater risk for developing cancer after nearly 5 years of follow-up compared with the general population and with other women treated with ART.

  14. Multiple stakeholder perceptions of assistive technology for individuals with cerebral palsy in New Zealand. (United States)

    Taherian, Sarvnaz; Davies, Claire


    This study sought to gain an understanding of the experiences and perspectives of assistive technology from different stakeholders in technology adoption, in the New Zealand context. A focus group was held with individuals with cerebral palsy (n = 5), service providers (n = 4), caregivers (n = 3) and a biomechanical engineer. The data recordings from the focus group were transcribed and coded using thematic analysis. Themes emerged around barriers imposed by the assessment process and training in assistive technology procedures, the influence of family members, the environment that assistive technology is used in, and psychosocial aspects of being able to participate and integrate into society. The results are similar to other literature, suggesting new innovations and changes are in dire need, to improve assistive technology experiences for all stakeholders. Implications for Research Service providers for assistive technology desire more effective training and support of existing and emerging technologies. Although the set procedure for acquiring assistive technology in New Zealand is comprehensive, incorporating multiple perspectives, it is difficult to follow through in practice. More innovative procedures are needed. The movement of Universal Design is significantly improving the perception of individuals with disabilities, and has enabled greater social inclusion. More assistive technology developers need to ensure that they incorporate these principles in their design process.

  15. Principles for fostering the transdisciplinary development of assistive technologies. (United States)

    Boger, Jennifer; Jackson, Piper; Mulvenna, Maurice; Sixsmith, Judith; Sixsmith, Andrew; Mihailidis, Alex; Kontos, Pia; Miller Polgar, Janice; Grigorovich, Alisa; Martin, Suzanne


    Developing useful and usable assistive technologies often presents complex (or "wicked") challenges that require input from multiple disciplines and sectors. Transdisciplinary collaboration can enable holistic understanding of challenges that may lead to innovative, impactful and transformative solutions. This paper presents generalised principles that are intended to foster transdisciplinary assistive technology development. The paper introduces the area of assistive technology design before discussing general aspects of transdisciplinary collaboration followed by an overview of relevant concepts, including approaches, methodologies and frameworks for conducting and evaluating transdisciplinary working and assistive technology design. The principles for transdisciplinary development of assistive technologies are presented and applied post hoc to the COACH project, an ambient-assisted living technology for guiding completion of activities of daily living by older adults with dementia as an illustrative example. Future work includes the refinement and validation of these principles through their application to real-world transdisciplinary assistive technology projects. Implications for rehabilitation Transdisciplinarity encourages a focus on real world 'wicked' problems. A transdisciplinary approach involves transcending disciplinary boundaries and collaborating with interprofessional and community partners (including the technology's intended users) on a shared problem. Transdisciplinarity fosters new ways of thinking about and doing research, development, and implementation, expanding the scope, applicability, and commercial viability of assistive technologies.

    Full Text Available Abstract The assisted reproductive technologies (ARTs have been used in the production of rhesus monkey offspring at the Oregon National Primate Research Center (ONPRC and that experience is summarized here. Additionally these technologies serve as a source of oocytes/embryos for monozygotic twinning, embryonic stem (ES cell derivation and cloning. High fertilization efficiencies were realized with conventional insemination or following the use of intracytoplasmic sperm injection (ICSI and approximately 50% of the resulting embryos grew in vitro to blastocysts. Both fresh and frozen sperm were employed in fertilization by ICSI and the resulting embryos could be low temperature stored for subsequent thawing and transfer when a synchronized recipient female was available or after shipment to another facility. Following the transfer of up to 3 embryos, an overall pregnancy rate of 30% was achieved with increasing rates dependent upon the number of embryos transferred. Singleton pregnancy outcomes following the transfer of ART produced embryos were similar to those observed in a control group of animals in the timed mated breeding colony at ONPRC. ICSI produced embryos were used in efforts to create monozygotic twins by blastomere separation or blastocyst splitting. While pregnancies were achieved following the transfer of demi-embryos, only one was a twin and it was lost to spontaneous abortion. ICSI produced embryos have also served as the source of blastocysts for the derivation of embryonic stem cells. These pluripotent cells hold potential for cell based therapies and we consider the monkey an important translational model in which to evaluate safety, efficacy and feasibility of regenerative medicine approaches based on the transplantation of stem cell-derived progeny. Finally, efforts to produce genetically-identical monkeys by nuclear transfer have been briefly summarized.

  20. Assistive technologies to overcome sarcopenia in ageing. (United States)

    Scott, Rachel A; Callisaya, Michele L; Duque, Gustavo; Ebeling, Peter R; Scott, David


    Sarcopenia is an age-related decline in skeletal muscle mass and function that results in disability and loss of independence. It affects up to 30% of older adults. Exercise (particularly progressive resistance training) and nutrition are key strategies in preventing and reversing declines in muscle mass, strength and power during ageing, but many sarcopenic older adults fail to meet recommended levels of both physical activity and dietary nutrient intake. Assistive technology (AT) describes devices or systems used to maintain or improve physical functioning. These may help sarcopenic older adults to maintain independence, and also to achieve adequate physical activity and nutrition. There is a paucity of research exploring the use of AT in sarcopenic patients, but there is evidence that AT, including walking aids, may reduce functional decline in other populations with disability. Newer technologies, such as interactive and virtual reality games, as well as wearable devices and smartphone applications, smart homes, 3D printed foods, exoskeletons and robotics, and neuromuscular electrical stimulation also hold promise for improving engagement in physical activity and nutrition behaviours to prevent further functional declines. While AT may be beneficial for sarcopenic patients, clinicians should be aware of its potential limitations. In particular, there are high rates of patient abandonment of AT, which may be minimised by appropriate training and monitoring of use. Clinicians should preferentially prescribe AT devices which promote physical activity. Further research is required in sarcopenic populations to identify strategies for effective use of current and emerging AT devices. Copyright © 2018 Elsevier B.V. All rights reserved.

    To compare clinical outcomes of in vitro fertilization (IVF) cycles with the use of gestational carriers (GCs) with non-GC IVF cycles. Retrospective cohort study of assisted reproductive technology (ART) cycles performed with (24,269) and without (1,313,452) the use of a GC. ART centers. Infertile patients seeking IVF with or without use of a GC. Autologous and donor oocyte cycles, fresh and cryopreserved embryo transfer cycles. Live birth rate (LBR), twin and high-order multiple birth rates. Approximately 2% of embryo transfers used a GC. Per embryo transfer, GCs had greater pregnancy rate and LBR across all IVF types compared with non-GC cycles in crude models and models adjusted a priori for potential confounders. For women with uterine-factor infertility, embryo transfer with the use of a GC resulted in a higher odds of live birth for autologous fresh embryos and for cryopreserved embryos compared with patients with non-uterine-factor infertility diagnoses. GC benefits LBRs for some patients seeking ART. The highest LBRs occurred when the indication for GC was uterine-factor infertility. Copyright © 2017 American Society for Reproductive Medicine.

  2. Application of microfluidic technologies to human assisted reproduction. (United States)

    Smith, Gary D; Takayama, Shuichi


    Microfluidics can be considered both a science and a technology. It is defined as the study of fluid behavior at a sub-microliter level and the investigation into its application to cell biology, chemistry, genetics, molecular biology and medicine. There are at least two characteristics of microfluidics, mechanical and biochemical, which can be influential in the field of mammalian gamete and preimplantation embryo biology. These microfluidic characteristics can assist in basic biological studies on sperm, oocyte and preimplantation embryo structure, function and environment. The mechanical and biochemical characteristics of microfluidics may also have practical and/or technical application(s) to assisted reproductive technologies (ART) in rodents, domestic species, endangered species and humans. This review will consider data in mammals, and when available humans, addressing the potential application(s) of microfluidics to assisted reproduction. There are numerous sequential steps in the clinical assisted reproductive laboratory process that work, yet could be improved. Cause and effect relations of procedural inefficiencies can be difficult to identify and/or remedy. Data will be presented that consider microfluidic applications to sperm isolation, oocyte cumulus complex isolation, oocyte denuding, oocyte mechanical manipulation, conventional insemination, intracytoplasmic sperm injection, embryo culture, embryo analysis and oocyte and embryo cryopreservation. While these studies have progressed in animal models, data with human gametes and embryos are significantly lacking. These data from clinical trials are requisite for making future evidence-based decisions regarding the application of microfluidics in human ART. © The Author 2017.

    The environmental problems related to the use of large quantities of tritium are reviewed. Particular attention is given to the health physics aspects arising from chronic and acute exposures to tritium, and to permissible release rates from large fusion devices. It is concluded that damage to man, including mutagenic effects, resulting from tritium intake is sufficiently known for maximum permissible dose rates to be defined, and that routine release rates from a stack of the order of 1000 Ci/y would not lead to dose rates to the public in excess of permissible limits. The technologies required in large fusion devices, like the experimental power reactor, are commented with a view on the future European fusion programme, emphasizing the need for research and development in the areas of tritium recovery from the exhaust and from the blanket, of tritium containment and waste disposal. Finally, licensing problems are discussed, suggesting a few supplementary points, insufficiently covered in the present or in the forthcoming regulations, especially those related to the transport and to the disposal of tritium wastes

    Hansen, Michele; Kurinczuk, Jennifer J; de Klerk, Nicholas; Burton, Peter; Bower, Carol


    To estimate the prevalence of major birth defects diagnosed by 6 years of age in all births and terminations of pregnancy for fetal anomaly conceived by assisted reproductive technology (when this included intracytoplasmic sperm injection and in vitro fertilization [IVF]) and the remainder of nonassisted reproductive technology-conceived children born in Western Australia from 1994 to 2002. This retrospective cohort study used data linkage between three population-based registers (Reproductive Technology Register, Western Australian Register of Developmental Anomalies, and Midwives' Notification of Birth System) to identify all assisted reproductive technology (n=2,911) and nonassisted reproductive technology (n=210,997) births with and without birth defects diagnosed by age 6 and all terminations of pregnancy for fetal anomaly. A major birth defect was diagnosed in 8.7% of assisted reproductive technology and 5.4% of nonassisted reproductive technology singletons (odds ratio [OR] 1.53, 95% confidence interval [CI] 1.30-1.79), as well as 7.1% of assisted reproductive technology twins and 5.9% of nonassisted reproductive technology twins of unlike sex (OR 1.08, 95% CI 0.77-1.51). The prevalence of birth defects in assisted reproductive technology singletons and twins decreased markedly over the study period. This change was evident across all three clinics contributing data over the whole study and was particularly marked for children conceived as a result of IVF. There has been a decrease in the prevalence of birth defects over time in children born as a result of assisted reproductive technology in Western Australia; however, the prevalence of major birth defects in assisted reproductive technology singletons remains increased compared with nonassisted reproductive technology singletons.

    Lersilp, Suchitporn; Putthinoi, Supawadee; Chakpitak, Nopasit


    Most students diagnosed with disabilities in Thai special education schools received assistive technologies, but this did not guarantee the greatest benefits. The purpose of this study was to survey the provision, use and needs of assistive technologies, as well as the perspectives of key informants regarding a model of providing them in special education schools. The participants were selected by the purposive sampling method, and they comprised 120 students with visual, physical, hearing or intellectual disabilities from four special education schools in Chiang Mai, Thailand; and 24 key informants such as parents or caregivers, teachers, school principals and school therapists. The instruments consisted of an assistive technology checklist and a semi-structured interview. Results showed that a category of assistive technologies was provided for students with disabilities, with the highest being "services", followed by "media" and then "facilities". Furthermore, mostly students with physical disabilities were provided with assistive technologies, but those with visual disabilities needed it more. Finally, the model of providing assistive technologies was composed of 5 components: Collaboration; Holistic perspective; Independent management of schools; Learning systems and a production manual for users; and Development of an assistive technology center, driven by 3 major sources such as Government and Private organizations, and Schools.

  10. A Rapid Prototyping Environment for Cooperative Advanced Driver Assistance Systems

    Directory of Open Access Journals (Sweden)

    Kay Massow


    Full Text Available Advanced Driver Assistance Systems (ADAS were strong innovation drivers in recent years, towards the enhancement of traffic safety and efficiency. Today’s ADAS adopt an autonomous approach with all instrumentation and intelligence on board of one vehicle. However, to further enhance their benefit, ADAS need to cooperate in the future, using communication technologies. The resulting combination of vehicle automation and cooperation, for instance, enables solving hazardous situations by a coordinated safety intervention on multiple vehicles at the same point in time. Since the complexity of such cooperative ADAS grows with each vehicle involved, very large parameter spaces need to be regarded during their development, which necessitate novel development approaches. In this paper, we present an environment for rapidly prototyping cooperative ADAS based on vehicle simulation. Its underlying approach is either to bring ideas for cooperative ADAS through the prototyping stage towards plausible candidates for further development or to discard them as quickly as possible. This is enabled by an iterative process of refining and assessment. We reconcile the aspects of automation and cooperation in simulation by a tradeoff between precision and scalability. Reducing precise mapping of vehicle dynamics below the limits of driving dynamics enables simulating multiple vehicles at the same time. In order to validate this precision, we also present a method to validate the vehicle dynamics in simulation against real world vehicles.

    Describe the use of assistive technology to enhance communication opportunities for older adults. A systematic review was conducted in two databases, PubMed and Web of Science, by using two different searches in each. The search was limited to original articles, in English language, including people aged 60 years and older that used any type of assistive technology for communication. The articles found in the initial search were filtered by title, abstracts and the remaining articles were fully read. Eighteen studies were included in this review after the reading of full-texts. Most of the studies included apparently healthy participants with communication limitations due to aging related changes and the others included people with some pathology that prevent them from normal communication. Four categories of assistive technology were identified: assistive technology for people with speech problems; robot or videoconferencing systems; Information and Communication Technologies and, other types of assistive technology for communication, such as hearing aids and scrapbooks. Assistive technology for communication of older adults is not only used by people with disabilities that prevent them from usual communication. They are mostly for older adults without a pathological communication problem.

  15. Providing Assistive Technology Applications as a Service Through Cloud Computing. (United States)

    Mulfari, Davide; Celesti, Antonio; Villari, Massimo; Puliafito, Antonio


    Users with disabilities interact with Personal Computers (PCs) using Assistive Technology (AT) software solutions. Such applications run on a PC that a person with a disability commonly uses. However the configuration of AT applications is not trivial at all, especially whenever the user needs to work on a PC that does not allow him/her to rely on his / her AT tools (e.g., at work, at university, in an Internet point). In this paper, we discuss how cloud computing provides a valid technological solution to enhance such a scenario.With the emergence of cloud computing, many applications are executed on top of virtual machines (VMs). Virtualization allows us to achieve a software implementation of a real computer able to execute a standard operating system and any kind of application. In this paper we propose to build personalized VMs running AT programs and settings. By using the remote desktop technology, our solution enables users to control their customized virtual desktop environment by means of an HTML5-based web interface running on any computer equipped with a browser, whenever they are.

  17. Thirty-five years of assisted reproductive technologies in Israel

    Directory of Open Access Journals (Sweden)

    Daphna Birenbaum-Carmeli


    Full Text Available Israel is known as a pronatalist country. Whether due to the Biblical commandment to ‘be fruitful and multiply’ or the traumas of the Holocaust and perennial wars, reproduction is a central life goal for most Israelis. Israeli women bear substantially more children than their counterparts in industrialized countries and view child-rearing as a key life accomplishment. These personal world-view and real-life individual quests take place in a context of equally pronatalist state policies and religious openness to assisted reproductive technologies. In this paper, I outline 35 years of assisted reproductive technologies in Israel by tracing a principal axis in the development of three major technologies of assisted reproduction: the proliferation of IVF-ICSI; the globalization of gamete donation; and the privatization of surrogacy. The paper is based on a policy analysis as well as various studies of assisted reproductive technologies, conducted in Israel over this period.

  18. Elaboration and validation of an assistive technology assessment questionnaire

    Directory of Open Access Journals (Sweden)

    Fernanda Jorge Guimarães


    Full Text Available Assistive Technologies consists of resources, methods, and strategies favoring autonomy and inclusion of elderly and people with disabilities, being scarce in the literature instruments assessing them. A methodology study conducted with a panel of specialists and people with visual impairment, aimed to elaborate and validate a questionnaire to assess educational assistive technology. To consider an item as valid, we used 80% as agreement percentage, and validity and reliability of the questionnaire were calculated. Assistive Technology was characterized in six attributes: objectives, access, clarity, structure and presentation, relevance and efficacy, interactivity, and 19 items were elaborated to compose the questionnaire. From those, 11 obtained percentages higher than 80%, seven were modified and one was excluded. The instrument Cronbach’s alpha was 0,822, guaranteeing validity and reliability of the tool to assess health education Assistive Technology, and therefore, its use is indicated.

  3. Assistive technologies for people with dementia: ethical considerations. (United States)

    Bennett, Belinda; McDonald, Fiona; Beattie, Elizabeth; Carney, Terry; Freckelton, Ian; White, Ben; Willmott, Lindy


    The sustainable development goals (SDGs) adopted by the United Nations in 2015 include a new target for global health: SDG 3 aims to "ensure healthy lives and promote well-being for all at all ages." Dementia care of good quality is particularly important given the projected increase in the number of people living with the condition. A range of assistive technologies have been proposed to support dementia care. However, the World Health Organization estimated in 2017 that only one in 10 of the 1 billion or more people globally who could benefit from these technologies in some way actually has access to them. For people living with dementia, there has been little analysis of whether assistive technologies will support their human rights in ways that are consistent with the United Nations Convention on the Rights of Persons with Disabilities. The aim of this paper is to examine the relevant provisions of the convention and consider their implications for the use of assistive technologies in dementia care. Assistive technologies can clearly play an important role in supporting social engagement, decision-making and advance planning by people living with dementia. However, concerns exist that some of these technologies also have the potential to restrict freedom of movement and intrude into privacy. In conclusion, an analysis of the implications of assistive technologies for human rights laws is needed to ensure that technologies are used in ways that support human rights and help meet the health-related SDG 3.

  4. Application requirements for Robotic Nursing Assistants in hospital environments (United States)

    Cremer, Sven; Doelling, Kris; Lundberg, Cody L.; McNair, Mike; Shin, Jeongsik; Popa, Dan


    In this paper we report on analysis toward identifying design requirements for an Adaptive Robotic Nursing Assistant (ARNA). Specifically, the paper focuses on application requirements for ARNA, envisioned as a mobile assistive robot that can navigate hospital environments to perform chores in roles such as patient sitter and patient walker. The role of a sitter is primarily related to patient observation from a distance, and fetching objects at the patient's request, while a walker provides physical assistance for ambulation and rehabilitation. The robot will be expected to not only understand nurse and patient intent but also close the decision loop by automating several routine tasks. As a result, the robot will be equipped with sensors such as distributed pressure sensitive skins, 3D range sensors, and so on. Modular sensor and actuator hardware configured in the form of several multi-degree-of-freedom manipulators, and a mobile base are expected to be deployed in reconfigurable platforms for physical assistance tasks. Furthermore, adaptive human-machine interfaces are expected to play a key role, as they directly impact the ability of robots to assist nurses in a dynamic and unstructured environment. This paper discusses required tasks for the ARNA robot, as well as sensors and software infrastructure to carry out those tasks in the aspects of technical resource availability, gaps, and needed experimental studies.

  5. Assisted reproductive technology surveillance -- United States, 2010. (United States)

    Sunderam, Saswati; Kissin, Dmitry M; Crawford, Sara; Anderson, John E; Folger, Suzanne G; Jamieson, Denise J; Barfield, Wanda D


    Since the first U.S. infant conceived with Assisted Reproductive Technology (ART) was born in 1981, both the use of advanced technologies to overcome infertility and the number of fertility clinics providing ART services have increased steadily in the United States. ART includes fertility treatments in which both eggs and sperm are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Women who undergo ART procedures are more likely to deliver multiple-birth infants than those who conceive naturally because more than one embryo might be transferred during a procedure. Multiple births pose substantial risks to both mothers and infants, including pregnancy complications, preterm delivery, and low birthweight infants. This report provides state-specific information on U.S. ART procedures performed in 2010 and compares infant outcomes that occurred in 2010 (resulting from procedures performed in 2009 and 2010) with outcomes for all infants born in the United States in 2010. 2010. In 1996, CDC began collecting data on all ART procedures performed in fertility clinics in the United States and U.S. territories, as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493). Data are collected through the National ART Surveillance System (NASS), a web-based data collecting system developed by CDC. In 2010, a total of 147,260 ART procedures performed in 443 U.S. fertility clinics were reported to CDC. These procedures resulted in 47,090 live-birth deliveries and 61,564 infants. The largest numbers of ART procedures were performed among residents of six states: California (18,524), New York (excluding New York City) (14,212), Illinois (10,110), Massachusetts (9,854), New Jersey (8,783), and Texas (8,754). These six states also had the highest number of live-birth deliveries as a result of ART procedures and together accounted for 48.0% of all ART procedures performed, 45.0% of all infants born

  6. A Unified Semantic Framework for the description of assistive technologies. (United States)

    Konstadinidou, Aggeliki; Kaklanis, Nikolaos; Votis, Konstantinos; Tzovaras, Dimitrios


    This paper presents the Semantic Alignment Tool, a unified, classified, ontological framework, for the description of assistive solutions that comprises information from different sources automatically. The Semantic Alignment Tool is a component of the Cloud4All/GPII infrastructure that enables users to add and/or modify descriptions of assistive technologies and align their specific settings with similar settings in an ontological model based on ISO 9999. The current work presents the interaction of the Semantic Alignment Tool with external sources that contain descriptions and metadata for Assistive Technologies (ATs) in order to achieve their synchronization in the same semantic model.

  8. Human-inspired sound environment recognition system for assistive vehicles (United States)

    González Vidal, Eduardo; Fredes Zarricueta, Ernesto; Auat Cheein, Fernando


    Objective. The human auditory system acquires environmental information under sound stimuli faster than visual or touch systems, which in turn, allows for faster human responses to such stimuli. It also complements senses such as sight, where direct line-of-view is necessary to identify objects, in the environment recognition process. This work focuses on implementing human reaction to sound stimuli and environment recognition on assistive robotic devices, such as robotic wheelchairs or robotized cars. These vehicles need environment information to ensure safe navigation. Approach. In the field of environment recognition, range sensors (such as LiDAR and ultrasonic systems) and artificial vision devices are widely used; however, these sensors depend on environment constraints (such as lighting variability or color of objects), and sound can provide important information for the characterization of an environment. In this work, we propose a sound-based approach to enhance the environment recognition process, mainly for cases that compromise human integrity, according to the International Classification of Functioning (ICF). Our proposal is based on a neural network implementation that is able to classify up to 15 different environments, each selected according to the ICF considerations on environment factors in the community-based physical activities of people with disabilities. Main results. The accuracy rates in environment classification ranges from 84% to 93%. This classification is later used to constrain assistive vehicle navigation in order to protect the user during daily activities. This work also includes real-time outdoor experimentation (performed on an assistive vehicle) by seven volunteers with different disabilities (but without cognitive impairment and experienced in the use of wheelchairs), statistical validation, comparison with previously published work, and a discussion section where the pros and cons of our system are evaluated.

  14. The use of assistive technology by occupational therapists in the Brazilian educational context: a literature review

    Directory of Open Access Journals (Sweden)

    Paloma Greicy Ferreira de Sousa


    Full Text Available This article aims to present, through a bibliographic revision, how occupational therapists have organized their discussions on the use of assistive technology resources at the school environment. An active search around this theme was performed in different databases, Scientific Eletronic Library Online (Scielo; Virtual Health Library (Bireme; Revista de Terapia Ocupacional da Universidade de São Paulo; Cadernos de Terapia Ocupacional da Universidade Federal de São Carlos, for the period between 2005, to the first trimester of 2013. The result showed the systematization of eleven studies related to assistive technology, occupational therapy, the educational context, and educational inclusion. The analysis revealed that occupational therapists worry about the need to educate teachers to use the assistive technology resources in the process of educating disabled students. The number of works found is still small considering the demand of the assistive technology and education area. There is a greater number of works about research reports, and fewer works about the theoretical foundation of assistive technology and its relation with Occupational Therapy in the school environment.

  18. Assistive technology for ultrasound-guided central venous catheter placement. (United States)

    Ikhsan, Mohammad; Tan, Kok Kiong; Putra, Andi Sudjana


    This study evaluated the existing technology used to improve the safety and ease of ultrasound-guided central venous catheterization. Electronic database searches were conducted in Scopus, IEEE, Google Patents, and relevant conference databases (SPIE, MICCAI, and IEEE conferences) for related articles on assistive technology for ultrasound-guided central venous catheterization. A total of 89 articles were examined and pointed to several fields that are currently the focus of improvements to ultrasound-guided procedures. These include improving needle visualization, needle guides and localization technology, image processing algorithms to enhance and segment important features within the ultrasound image, robotic assistance using probe-mounted manipulators, and improving procedure ergonomics through in situ projections of important information. Probe-mounted robotic manipulators provide a promising avenue for assistive technology developed for freehand ultrasound-guided percutaneous procedures. However, there is currently a lack of clinical trials to validate the effectiveness of these devices.

    What were utilization, outcomes and practices in assisted reproductive technology (ART) globally in 2008, 2009 and 2010? Global utilization and effectiveness remained relatively constant despite marked variations among countries, while the rate of single and frozen embryo transfers (FETs) increased with a concomitant slight reduction in multiple birth rates. ART is widely practised in all regions of the world. Monitoring utilization, an approximation of availability and access, as well as effectiveness and safety is an important component of universal access to reproductive health. This is a retrospective, cross-sectional survey on utilization, effectiveness and safety of ART procedures performed globally from 2008 to 2010. Between 58 and 61 countries submitted data from a total of nearly 2500 ART clinics each year. Aggregate country data were processed and analyzed based on forms and methods developed by the International Committee for Monitoring Assisted Reproductive Technologies (ICMART). Results are presented at country, regional and global level. For the years 2008, 2009 and 2010, >4 461 309 ART cycles were initiated, resulting in an estimated 1 144 858 babies born. The number of aspirations increased by 6.4% between 2008 and 2010, while FET cycles increased by 27.6%. Globally, ART utilization remained relatively constant at 436 cycles/million in 2008 and 474 cycles/million population in 2010, but with a wide country range of 8-4775 cycles/million population. ICSI remained constant at around 66% of non-donor aspiration cycles. The IVF/ICSI combined delivery rate (DR) per fresh aspiration was 19.8% in 2008; 19.7% in 2009 and 20.0% in 2010, with corresponding DRs for FET of 18.8, 19.7 and 20.7%. In fresh non-donor cycles, single embryo transfer increased from 25.7% in 2008 to 30.0% in 2010, while the average number of embryos transferred fell from 2.1 to 1.9, again with wide regional variation. The rates of twin deliveries following fresh non-donor transfers

    Alves, Cássia Cristiane de Freitas; Monteiro, Gelse Beatriz Martins; Rabello, Suzana; Gasparetto, Maria Elisabete Rodrigues Freire; de Carvalho, Keila Monteiro


    Verify the application of assistive technology, especially information technology in the education of blind and low-vision students from the perceptions of their teachers. Descriptive survey study in public schools in three municipalities of the state of São Paulo, Brazil. The sample comprised 134 teachers. According to the teachers' opinions, there are differences in the specificities and applicability of assistive technology for blind and low-vision students, for whom specific computer programs are important. Information technology enhances reading and writing skills, as well as communication with the world on an equal basis, thereby improving quality of life and facilitating the learning process. The main reason for not using information technology is the lack of planning courses. The main requirements for the use of information technology in schools are enough computers for all students, advisers to help teachers, and pedagogical support. Assistive technology is applied to education of students with visual impairment; however, teachers indicate the need for infrastructure and pedagogical support. Information technology is an important tool in the inclusion process and can promote independence and autonomy of students with visual impairment.

    Rami Yared


    Full Text Available While elderly people perform their daily indoor activities, they are subjected to several risks. To improve the quality of life of elderly people and promote healthy aging and independent living, elderly people need to be provided with an assistive technology platform to rely on during their activities. We reviewed the literature and identified the major indoor risks addressed by assistive technology that elderly people face during their indoor activities. In this paper, we identify these risks as: fall, wrong self-medication management, fire, burns, intoxication by gas/smoke, and the risk of inactivity. In addition, we discuss the existing assistive technology systems and classify the risk detection algorithms, techniques and the basic system principles and interventions to enhance safety of elderly people.

  8. Technology Survey Assistance Tool Focusing on Their Advantages (United States)

    Nishiyama, Risa; Takeuchi, Hironori; Watanabe, Hideo; Nasukawa, Tetsuya

    It is important for R&D managers, consultants, and other people seeking broad knowledge in technology fields to survey technical literature such as research papers, white papers, and technology news articles. One of the important kinds of information for those people regards the effectiveness of new technologies in their own businesses. General search engines are good at selecting documents revealing the details of a specific technology or a technology field, but it is hard to obtain useful information about how a technology will apply to individual business cases from such search results. There is a need for a technology survey assistance tool that helps users find technologies with suitable capabilities. In this paper, two technical tasks were tackled to develop the prototype of this assistance tool: Extraction of advantage phrases and scoring for the advantage phrases to find novel applications in the target technology field. We describe a new method to identify advantage phrases in technical documents and our scoring function that gives higher scores to novel applications of the technology. The results of evaluations showed our phrase identification method with only a few phrasal patterns performs almost as well as human annotators, and the proposed scoring conforms better to the decisions made by professionals than random sort.

  9. Middle school special education teachers' perceptions and use of assistive technology in literacy instruction. (United States)

    Flanagan, Sara; Bouck, Emily C; Richardson, Jennifer


    In this research the authors examined middle school special education teachers' perceptions of assistive technology during literacy instruction with students with high incidence disabilities. A survey explored the use, effectiveness, and factors impacting use or effectiveness of assistive technology for literacy teaching and learning. Results suggested teachers' perceived assistive technology to be an effective tool for literacy, but use it minimally. When assistive technology was used, teachers indicated it was an effective literacy support. Teachers also reported barriers to using assistive technology in literacy including cost, usability, and lack of training/experience. However, factors such as previous successful experiences with assistive technology and assistive technology supporting students' learning encouraged assistive technology use. The consistency of teachers' reports of needing more experience and knowledge in assistive technology to fully use it suggests implications for preservice preparation such as providing additional experiences and information on assistive technology.

  11. Dental nursing education and the introduction of technology-assisted learning. (United States)

    Sheridan, C; Gorman, T; Claffey, N


    The aim of this paper is to explore the profile of dental nursing students in the National Dental Nurse Training Programme of Ireland and their adjustment to a technology-assisted learning environment. Evaluation by students of the course and their reactions to the course were analysed. Dental nurses must possess the skills and knowledge to proficiently function in the modern day dental surgery. The implementation of a dental nurse programme that is heavily reliant on technology has started to create a group of dental nurses equipped with basic skills to access and retrieve information over a lifetime. However, the transition to a technology-assisted learning environment including online learning activities requires adaptation and expertise by educators and students alike. Careful evaluation and stakeholder feedback is imperative in the creation and maintaining of a quality programme. In conclusion, the students in this study responded well to the transition to a technology-based learning environment. Furthermore, the findings of this study suggest that the use of an online environment is an effective and stimulating learning environment for the students of a dental nurse programme; however, familiarity skills and knowledge of information technology is a prerequisite for success.

  12. Assisting autistic children with wireless EOG technology. (United States)

    Rapela, Joaquin; Lin, Tsong-Yan; Westerfield, Marissa; Jung, Tzyy-Ping; Townsend, Jeanne


    We propose a novel intervention to train the speed and accuracy of attention orienting and eye movements in Autism Spectrum Disorder (ASD). Training eye movements and attention could not only affect those important functions directly, but could also result in broader improvement of social communication skills. To this end we describe a system that would allow ASD children to improve their fixation skills while playing a computer game controlled by an eye tracker. Because this intervention will probably be time consuming, this system should be designed to be used at homes. To make this possible, we propose an implementation based on wireless and dry electrooculography (EOG) technology. If successful, this system would develop an approach to therapy that would improve clinical and behavioral function in children and adults with ASD. As our initial steps in this direction, here we describe the design of a computer game to be used in this system, and the predictions of gaze position from EOG data recorded while a subject played this game.

  15. Forecasting the impact of virtual environment technology on maintenance training (United States)

    Schlager, Mark S.; Boman, Duane; Piantanida, Tom; Stephenson, Robert


    To assist NASA and the Air Force in determining how and when to invest in virtual environment (VE) technology for maintenance training, we identified possible roles for VE technology in such training, assessed its cost-effectiveness relative to existing technologies, and formulated recommendations for a research agenda that would address instructional and system development issues involved in fielding a VE training system. In the first phase of the study, we surveyed VE developers to forecast capabilities, maturity, and estimated costs for VE component technologies. We then identified maintenance tasks and their training costs through interviews with maintenance technicians, instructors, and training developers. Ten candidate tasks were selected from two classes of maintenance tasks (seven aircraft maintenance and three space maintenance) using five criteria developed to identify types of tasks most likely to benefit from VE training. Three tasks were used as specific cases for cost-benefit analysis. In formulating research recommendations, we considered three aspects of feasibility: technological considerations, cost-effectiveness, and anticipated R&D efforts. In this paper, we describe the major findings in each of these areas and suggest research efforts that we believe will help achieve the goal of a cost-effective VE maintenance training system by the next decade.

  16. Envisioning Science Environment Technology and Society (United States)

    Maknun, J.; Busono, T.; Surasetja, I.


    Science Environment Technology and Society (SETS) approach helps students to connect science concept with the other aspects. This allows them to achieve a clearer depiction of how each concept is linked with the other concepts in SETS. Taking SETS into account will guide students to utilize science as a productive concept in inventing and developing technology, while minimizing its negative impacts on the environment and society. This article discusses the implementation of Sundanese local wisdoms, that can be found in the local stilt house (rumah panggung), in the Building Construction subject in vocational high school on Building Drawing Technique expertise. The stilt house structural system employs ties, pupurus joints, and wedges on its floor, wall, and truss frames, as well as its beams. This local knowledge was incorporated into the Building Construction learning program and applied on the following basic competences: applying wood’s specification and characteristics for building construction, managing wood’s specification and characteristics for building construction, analyzing building structure’s type and function based on their characteristics, reasoning building structure’s type and function based on their characteristics, categorizing wood construction works, and reasoning wood construction works. The research result is the Sundanese traditional-local-wisdom-based learning design of the Building Construction subject.

  18. Modeling Users, Context and Devices for Ambient Assisted Living Environments (United States)

    Castillejo, Eduardo; Almeida, Aitor; López-de-Ipiña, Diego; Chen, Liming


    The participation of users within AAL environments is increasing thanks to the capabilities of the current wearable devices. Furthermore, the significance of considering user's preferences, context conditions and device's capabilities help smart environments to personalize services and resources for them. Being aware of different characteristics of the entities participating in these situations is vital for reaching the main goals of the corresponding systems efficiently. To collect different information from these entities, it is necessary to design several formal models which help designers to organize and give some meaning to the gathered data. In this paper, we analyze several literature solutions for modeling users, context and devices considering different approaches in the Ambient Assisted Living domain. Besides, we remark different ongoing standardization works in this area. We also discuss the used techniques, modeled characteristics and the advantages and drawbacks of each approach to finally draw several conclusions about the reviewed works. PMID:24643006

  1. A Review of Technology-Assisted Interventions for Diabetes Prevention. (United States)

    Grock, Shira; Ku, Jeong-Hee; Kim, Julie; Moin, Tannaz


    The high prevalence of prediabetes and success of the diabetes prevention program (DPP) has led to increasing efforts to provide readily accessible, cost-effective DPP interventions to the general public. Technology-assisted DPP interventions are of particular interest since they may be easier to widely distribute and sustain as compared to traditional in-person DPP. The purpose of this article is to provide an overview of currently available technology-assisted DPP interventions. This review focuses on studies that have examined the use of mobile phone text messaging, smartphone/web-based apps, and telehealth programs to help prevent or delay the onset of incident type 2 diabetes. While there is variability in the results of studies focused on technology-assisted DPP and weight loss interventions, there is evidence to suggest that these programs have been associated with clinically meaningful weight loss and can be cost-effective. Patients who are at risk for diabetes can be offered technology-assisted DPP and weight loss interventions to lower their risk of incident diabetes. Further research should determine what specific combination of intervention features would be most successful.

  10. Assistive technologies in reducing caregiver burden among informal caregivers of older adults: a systematic review. (United States)

    Madara Marasinghe, Keshini


    The world population is rapidly ageing. As population age, the incidence of functional limitations increases, demanding higher levels of care from caregivers. Assistive technologies improve individuals' functioning, independence, well-being and quality of life. By increasing independence of older adults, assistive technologies decrease workloads required from informal caregivers. This review investigates, evaluates, and synthesises existing findings to examine whether and how assistive technologies reduce caregiver burden. Databases searched included MEDLINE, EMBASE, Scopus, and Cochrane Library. Three groups of keywords were combined: those relating to assistive technology, caregiver burden, and older adults. Two theories emerged from the analysis of study results. Caregivers reported that assistive technologies decrease caregiver burden. However, caregivers had concerns that assistive technologies could add to caregiver burden, highlighting the limitations of assistive technology. As suggested by a majority of the studies in this review, assistive technologies contribute to reducing caregiver burden among caregivers of older adults. Assistive technologies assisted caregivers by reducing time, levels of assistance and energy put towards caregiving, anxiety and fear, task difficulty, safety risk particularly for activities requiring physical assistance and increasing the independence of the users. Further research is required to better understand limitations of assistive technologies. Implications for Rehabilitation Support for informal caregivers of older adults need more attention and recognition. Assistive technologies can reduce caregiver burden among informal caregivers of older adults. Further research is required to better understand the effectiveness of assistive technologies in reducing caregiver burden as well as limitations and barriers associated with using assistive technologies.

    Williamson, Tracey; Kenney, Laurence; Barker, Anthony T; Cooper, Glen; Good, Tim; Healey, Jamie; Heller, Ben; Howard, David; Matthews, Martin; Prenton, Sarah; Ryan, Julia; Smith, Christine


    To appraise the application of accepted good practice guidance on public involvement in assistive technology research and to identify its impact on the research team, the public, device and trial design. Critical reflection and within-project evaluation were undertaken in a case study of the development of a functional electrical stimulation device. Individual and group interviews were undertaken with lay members of a 10 strong study user advisory group and also research team members. Public involvement was seen positively by research team members, who reported a positive impact on device and study designs. The public identified positive impact on confidence, skills, self-esteem, enjoyment, contribution to improving the care of others and opportunities for further involvement in research. A negative impact concerned the challenge of engaging the public in dissemination after the study end. The public were able to impact significantly on the design of an assistive technology device which was made more fit for purpose. Research team attitudes to public involvement were more positive after having witnessed its potential first hand. Within-project evaluation underpins this case study which presents a much needed detailed account of public involvement in assistive technology design research to add to the existing weak evidence base. The evidence base for impact of public involvement in rehabilitation technology design is in need of development. Public involvement in co-design of rehabilitation devices can lead to technologies that are fit for purpose. Rehabilitation researchers need to consider the merits of active public involvement in research.

    Ana Cristina de Jesus Alves


    Full Text Available Introduction: The latest international researches seek to understand the factors affecting the successful use of assistive technology devices through studies regarding the assessments systematizing; abandonment of devices; or theoric models that consider the aspects of those devices implementation. In Brazil the researches are focused on developing new technologies and there are still not sufficient studies related to the successful use of devices and ways of assistive technology implementation. Objective: To identify conceptual models used for indication and implementation of assistive technology devices. Method: Literature review. The survey was conducted in six databases: CINAHAL, Eric, GALE, LILACS, MEDLINE e PsycInfo. A critical analysis described by Grant and Booth was used. Results: There are no records of a Brazilian survey and among 29 selected articles, 17 conceptual models used in the area of AT were found; of these, 14 were specific to AT. The results showed that the new conceptual models of TA are under development and the conceptual model “Matching Person and Technology – MPT” was the most mentioned. Conclusion: We can observe that the practices related to TA area in international context shows a correlation with conceptual models, thus, we hope this study might have the capacity to contribute for the propagation of this precepts at national level

  13. MAS: Malware Analysis System Based on Hardware-Assisted Virtualization Technology (United States)

    Kim, Taehyoung; Kim, Inhyuk; Min, Changwoo; Eom, Young Ik

    There are many analysis techniques in order to analyze malicious codes. However, recently malicious codes often evade detection using stealthy obfuscation techniques, and attack computing systems. We propose an enhanced dynamic binary instrumentation using hardware-assisted virtualization technology. As a machine-level analyzer, our system can be isolated from almost the whole threats of malware, and provides single step analysis environment. Proposed system also supports rapid system call analysis environment. We implement our malware analysis system (referred as MAS) on the KVM hypervisor with Intel VT-x virtualization support. Our experiments with benchmarks show that the proposed system provides efficient analysis environment with low overhead.

  15. Impact of Aging and Cognition on Hearing Assistive Technology Use. (United States)

    Jorgensen, Lindsey E; Messersmith, Jessica J


    Many factors go into appropriate recommendation and use of hearing assistive technology (HAT). The aging auditory system presents with its own complications and intricacies; there are many types of age-related hearing loss, and it is possible that the underlying cause of hearing loss can significantly impact the recommendations and performance with HATs. The audiologist should take into consideration peripheral and central auditory function when selecting HATs for the aging adult population as well as when selecting appropriate types of technology including personal sound amplification products, hearing aids, cochlear implants, and other assistive technology. The cognitive ability of the patient plays a central role in the recommendations of HAT. It is possible that the use of HATs could mitigate some of the effects of cognitive decline and thus should be considered as early as possible. Assessment of ability and appropriate recommendations are crucial to consistent use of HAT devices.

  17. An assistive technology for hearing-impaired persons: analysis, requirements and architecture. (United States)

    Mielke, Matthias; Grunewald, Armin; Bruck, Rainer


    In this contribution, a concept of an assistive technology for hearing-impaired and deaf persons is presented. The concept applies pattern recognition algorithms and makes use of modern communication technology to analyze the acoustic environment around a user, identify critical acoustic signatures and give an alert to the user when an event of interest happened. A detailed analysis of the needs of deaf and hearing-impaired people has been performed. Requirements for an adequate assisting device have been derived from the results of the analysis, and have been turned into an architecture for its implementation that will be presented in this article. The presented concept is the basis for an assistive system which is now under development at the Institute of Microsystem Engineering at the University of Siegen.

  18. Vision based assistive technology for people with dementia performing activities of daily living (ADLs): an overview (United States)

    As'ari, M. A.; Sheikh, U. U.


    The rapid development of intelligent assistive technology for replacing a human caregiver in assisting people with dementia performing activities of daily living (ADLs) promises in the reduction of care cost especially in training and hiring human caregiver. The main problem however, is the various kinds of sensing agents used in such system and is dependent on the intent (types of ADLs) and environment where the activity is performed. In this paper on overview of the potential of computer vision based sensing agent in assistive system and how it can be generalized and be invariant to various kind of ADLs and environment. We find that there exists a gap from the existing vision based human action recognition method in designing such system due to cognitive and physical impairment of people with dementia.

    Chaurasia, Priyanka; McClean, Sally I; Nugent, Chris D; Cleland, Ian; Zhang, Shuai; Donnelly, Mark P; Scotney, Bryan W; Sanders, Chelsea; Smith, Ken; Norton, Maria C; Tschanz, JoAnn


    Assistive technologies have been identified as a potential solution for the provision of elderly care. Such technologies have in general the capacity to enhance the quality of life and increase the level of independence among their users. Nevertheless, the acceptance of these technologies is crucial to their success. Generally speaking, the elderly are not well-disposed to technologies and have limited experience; these factors contribute towards limiting the widespread acceptance of technology. It is therefore important to evaluate the potential success of technologies prior to their deployment. The research described in this paper builds upon our previous work on modelling adoption of assistive technology, in the form of cognitive prosthetics such as reminder apps and aims at identifying a refined sub-set of features which offer improved accuracy in predicting technology adoption. Consequently, in this paper, an adoption model is built using a set of features extracted from a user's background to minimise the likelihood of non-adoption. The work is based on analysis of data from the Cache County Study on Memory and Aging (CCSMA) with 31 features covering a range of age, gender, education and details of health condition. In the process of modelling adoption, feature selection and feature reduction is carried out followed by identifying the best classification models. With the reduced set of labelled features the technology adoption model built achieved an average prediction accuracy of 92.48% when tested on 173 participants. We conclude that modelling user adoption from a range of parameters such as physical, environmental and social perspectives is beneficial in recommending a technology to a particular user based on their profile.

  20. Use of Assisted Reproductive Technologies for Livestock Development

    Directory of Open Access Journals (Sweden)

    Vikrama Chakravarthi. P and N. Sri Balaji


    Full Text Available Genetic improvement of farm animals is a prime concern over the years for researchers. Several reproductive technologies have been employed to achieve this. Assisted reproductive technologies like Artificial insemination, Superovulation, In vitro Fertilization, Embryo Transfer have been introduced to overcome reproductive problems, to increase the offspring from selected female’s and to reduce the generation intervals in farm animals. The progress achieved during the last few years in the assisted reproductive technologies field has been phenomenal. Artificial Insemination (AI is the most effective method being used for the genetic improvement of animals. Reproductive capacity and efficiency has been improved tremendously since the introduction of artificial insemination. The development of cloning using various cells from the animal body has created opening of a fascinating scientific arena. These technologies have been propounded as saviors of indigenous livestock breeds. These alternative reproductive techniques are available not only for manipulation of reproductive processes but also proven to be powerful tools in curbing the spread of vertically transmitted diseases. The successful reproductive technologies such as AI and Embryo transfer need be applied on a large scale, emerging biotechnogies such as MOET, IVF and Cloning provides powerful tool for rapidly changing the animal populations, genetically. This advanced reproduction technologies will definitely play an important role in the future perspective and visions for efficient reproductive performance in livestock. [Vet.

  1. Use of assistive technology devices in mainstream schools: students' perspective. (United States)

    Hemmingsson, Helena; Lidström, Helene; Nygård, Louise


    The use and nonuse of assistive technology devices in school by students with physical disabilities was investigated, and the students' experiences in using these devices is described. We used a mixed-methods approach with predominantly qualitative methods to collect and analyze data, which included observations of and interviews with 20 students with physical disabilities and the number and type of assistive technology devices provided. It is vital that devices be integrated into educational practice and that students experience immediate benefits for their function in everyday school activities without detrimental effects on their social participation. The latter was often more important than being able to perform activities independently. The students adopted both a functional and a psychosocial perspective of their devices, and providers should neglect neither. Children and youth need both verbal information and practical experience using devices to be able to make informed decisions.

  2. Assistive/rehabilitation technology, disability, and service delivery models. (United States)

    Adya, Meera; Samant, Deepti; Scherer, Marcia J; Killeen, Mary; Morris, Michael W


    The United Nation's Millennium Development Goals do not explicitly articulate a focus on disability; similar failures in the past resulted in research, policy, and practice that are not generalizable and did not meet the needs of persons with disabilities since they were developed for an "average" population. Academics and professionals in health and other disciplines should have a knowledge base in evidence-based practices that improve well-being and participation of people with disabilities through effective service delivery of assistive technology. Grounded by a theoretical framework that incorporates a multivariate perspective of disability that is acknowledged in the convention on the rights of persons with disabilities and the World Health Organization's International Classification of Functioning, Disability and Health, we present a review of models of assistive technology service delivery and call for future syntheses of the fragmented evidence base that would permit a comparative effectiveness approach to evaluation.

  3. Technology-assisted rehabilitation interventions following pediatric brain injury. (United States)

    Wade, Shari L; Narad, Megan E; Shultz, Emily L; Kurowski, Brad G; Miley, Aimee E; Aguilar, Jessica M; Adlam, Anna-Lynne R


    Following traumatic brain injury (TBI), children experience a variety of physical, motor, speech, and cognitive deficits that can have a long-term detrimental impact. The emergence and popularity of new technologies has led to research into the development of various apps, gaming systems, websites, and robotics that might be applied to rehabilitation. The objective of this narrative review was to describe the current literature regarding technologically-assisted interventions for the rehabilitation of motor, neurocognitive, behavioral, and family impairments following pediatric TBI. We conducted a series of searches for peer-reviewed manuscripts published between 2000 and 2017 that included a technology-assisted component in the domains of motor, language/communication, cognition, behavior, social competence/functioning, family, and academic/school-based functioning. Findings suggested several benefits of utilizing technology in TBI rehabilitation including facilitating engagement/adherence, increasing access to therapies, and improving generalizability across settings. There is fairly robust evidence regarding the efficacy of online family problem-solving therapy in improving behavior problems, executive functioning, and family functioning. There was less compelling, but still promising, evidence regarding the efficacy other technology for motor deficits, apps for social skills, and computerized programs for cognitive skills. Overall, many studies were limited in the rigor of their methodology due to small heterogeneous samples and lack of control groups. Technology-assisted interventions have the potential to enhance pediatric rehabilitation after TBI. Future research is needed to further support their efficacy with larger controlled trials and to identify characteristics of children who are most likely to benefit.

    Muftic, Sead


    Under this project SETECS performed research, created the design, and the initial prototype of three groups of security technologies: (a) middleware security platform, (b) Web services security, and (c) group security system. The results of the project indicate that the three types of security technologies can be used either individually or in combination, which enables effective and rapid deployment of a number of secure applications in open networking environments. The middleware security platform represents a set of object-oriented security components providing various functions to handle basic cryptography, X.509 certificates, S/MIME and PKCS No.7 encapsulation formats, secure communication protocols, and smart cards. The platform has been designed in the form of security engines, including a Registration Engine, Certification Engine, an Authorization Engine, and a Secure Group Applications Engine. By creating a middleware security platform consisting of multiple independent components the following advantages have been achieved - Object-oriented, Modularity, Simplified Development, and testing, Portability, and Simplified extensions. The middleware security platform has been fully designed and a preliminary Java-based prototype has been created for the Microsoft Windows operating system. The Web services security system, designed in the project, consists of technologies and applications that provide authentication (i.e., single sign), authorization, and federation of identities in an open networking environment. The system is based on OASIS SAML and XACML standards for secure Web services. Its topology comprises three major components: Domain Security Server (DSS) is the main building block of the system Secure Application Server (SAS) Secure Client In addition to the SAML and XACML engines, the authorization system consists of two sets of components An Authorization Administration System An Authorization Enforcement System Federation of identities in multi

    Directory of Open Access Journals (Sweden)


    Full Text Available The national School Census revealed that 702,603 disabled people were enrolled in regular educationin 2010. The use of assistive technology resources in the school context has been indicated to favor the executionof tasks and the access to educational content and school environments and, consequently, help disabledindividuals’ learning. However, there are few studies showing the impact of these resources in the educationprocess of children with physical disabilities. The aim of this study was to identify, from the teacher’s viewpoint,the contributions and difficulties in the use of technology resources with students with cerebral palsy, focusingon those with severe motor impairment, attending regular education. The study included five teachers of these students who were using assistive technology resources in the execution of writing and/or communicationassignments. Semi-structured interviews were conducted and data were analyzed following the CollectiveSubject Discourse (CSD technique. Results indicated that assistive technology resources are already includedin regular schools and that they have brought contributions to the education process of children with cerebralpalsy in regular class; nevertheless, they are being implemented without systematization, monitoring and/orpartnerships. The study pointed to the need to consider the opinions and requirements of the people involved inthe context where the use of technology is inserted.

    Directory of Open Access Journals (Sweden)

    Ivan Anatol’yevich Bliznets


    Full Text Available The spread of disruptive technology in the digital era is the ruling condition of modern sustainable development. The authors proceed from the fact that legal tools for the creation and use, protection of advanced technologies provide the technology transfer process from the owner to interested parties for further practical, commercial application or further improvement. The article analyzes the legal positions of the concept of technology, legal ways to use modern technologies, stages of their implementation and practical application. In the innovation process legal mechanism in combination with the modern means of innovative development stimulates the creation and transfer of new technologies and at the same time it is a key factor for sustainable development in the context of modern digital technology revolution. In the modern digital revolution, the technology transfer acquires new features and ways for the dissemination of technical innovation, which creates new challenges for legal theory and practice, and legal tools should meet the challenges of the time.

  15. Identifying the Potential for Robotics to Assist Older Adults in Different Living Environments (United States)

    Mitzner, Tracy L.; Chen, Tiffany L.; Kemp, Charles C.; Rogers, Wendy A.


    As the older adult population grows and becomes more diverse, so will their needs and preferences for living environments. Many adults over 65 years of age require some assistance [1, 2]; yet it is important for their feelings of well-being that the assistance not restrict their autonomy [3]. Not only is autonomy correlated with quality of life [4], autonomy enhancement may improve functionality [2, 5]. The goal of this paper is to provide guidance for the development of technology to enhance autonomy and quality of life for older adults. We explore the potential for robotics to meet these needs. We evaluated older adults' diverse living situations and the predictors of residential moves to higher levels of care in the United States. We also examined older adults' needs for assistance with activities of daily living (ADLs), instrumental activities of daily living (IADLs), and medical conditions when living independently or in a long-term care residence. By providing support for older adults, mobile manipulator robots may reduce need-driven, undesired moves from residences with lower levels of care (i.e., private homes, assisted living) to those with higher levels of care (i.e., skilled nursing).

    Schwartze, Jonas; Schrom, Harald; Wolf, Klaus-Hendrik; Marschollek, Michael


    Current Ambient Assisted Living (AAL) environments lack integration of sensors and actuators of other sub-domains. Creating technical and organizational integration is addressed by the BASIS project (Build Automation by a Scalable and Intelligent System), which aims to build a cross-domain home bus system. The main objective of this paper is to present an overview of design, architecture and state of realization of BASIS by describing the requirements development process, underlying hardware design and software architecture. We built a distributed system of one independent building manager with several redundantly meshed segment controllers, each controlling a bus segment with any number of bus nodes. The software system layer is divided into logical partitions representing each sub-domain. Structured data storage is possible with a special FHIR based home centered data warehouse. The system has been implemented in six apartments running under daily living conditions. BASIS integrates a broad range of sub-domains, which poses challenges to all project partners in terms of a common terminology, and project management methods, but enables development of inter-domain synergies like using the same sensor and actuator hardware for a broad range of services and use cases.

  19. Context management: toward assessing quality of context parameters in a ubiquitous ambient assisted living environment

    Directory of Open Access Journals (Sweden)

    Débora Cabral Nazário


    Full Text Available This paper provides an approach to assessing Quality of Context (QoC parameters in a ubiquitous Ambient Assisted Living (AAL environment. Initially, the study presents a literature review on QoC, generating taxonomy. Then it introduces the context management architecture used. The proposal is verified with the Siafu simulator in an AAL scenario where the user’s health is monitored with information about blood pressure, heart rate and body temperature. Considering some parameters, the proposed QoC assessment allows verifying the extent to which the context information is up-to-date, valid, accurate, complete and significant. The implementation of this proposal might mean a big social impact and a technological innovation applied to AAL, at the disposal and support of a significant number of individuals such as elderly or sick people, and with a more precise technology.

    Sato, Masakazu; Koizumi, Minako; Hino, Takahiro; Takahashi, Yu; Nagashima, Natsuki; Itaoka, Nao; Ueshima, Chiharu; Nakata, Maki; Hasumi, Yoko


    Laparoscopic surgery is less invasive than open surgery and is now common in various medical fields. However, laparoscopic surgery is more difficult than open surgery and often requires additional time for the operator to achieve mastery. Therefore, we investigated the use of assistive technology for uniform laparoscopic surgery. We used the OpenCV2 library for augmented reality with an ArUco marker to detect and estimate forceps positioning. We used Sense HAT as the gyro sensor. The development platforms used were Mac OS X 10.11.3 and Raspberry Pi 3, model B. By attaching the ArUco marker to the needle holder, we could draw a line vertically to the marker. When the needle was held, a cube could be imagined, and both the needle and lines could be used to determine the appropriate position. By attaching the gyro sensor to the camera, we could detect its angle of rotation. We obtained stabilized images by rotating the image by the detected degrees; this was possible for any camera position. Assistive technology allowed us to obtain consecutive converted images in real time and may be readily applicable to clinical practice. © 2018 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

  11. Using assistive technology services at differing levels of care: healthy older couples' perceptions. (United States)

    Harrefors, Christina; Axelsson, Karin; Sävenstedt, Stefan


    The aim of the study was to describe healthy older couples' perceptions of using assistive technology services when needing assistance with care. The use of information technology-based assistive technology services in elder care has increased as a result of an increase of care performed in private homes. The use of assistive technology services in care of older people at home has been evaluated as something positive by patients, relatives and nursing staff, while as resistance to their increased use has also been noted. Twelve healthy couples, aged over 70 years, from northern Sweden were interviewed in 2005 about their perceptions of using assistive technology services in the case of being in need of assistance with personal care. Open, individual semi-structured interviews supported by written vignettes describing three levels of caring needs were used and the data analysed with content analysis. The findings were interpreted as one main theme with three categories: Asset or threat depends on caring needs and abilities. Three categories were identified within the theme: Assistive technology services provide an opportunity; The consequences of using assistive technology services are hard to anticipate; and Fear of assistive technology services when completely dependent on care. Trust and security in the care of older people who are severely ill, dependent on care and living at home should be a hallmark in using assistive technology services. Human presence is an important dimension and must be considered when developing concepts for use of assistive technology services.

  14. Immersive Environment Technologies for Mars Exploration (United States)

    Wright, John R.; Hartman, Frank


    JPL's charter includes the unmanned exploration of the Solar System. One of the tools for exploring other planets is the rover as exemplified by Sojourner on the Mars Pathfinder mission. The light speed turnaround time between Earth and the outer planets precludes the use of teleoperated rovers so autonomous operations are built in to the current and upcoming generation devices. As the level of autonomy increases, the mode of operations shifts from low-level specification of activities to a higher-level specification of goals. To support this higher-level activity, it is necessary to provide the operator with an effective understanding of the in-situ environment and also the tools needed to specify the higher-level goals. Immersive environments provide the needed sense of presence to achieve this goal. Use of immersive environments at JPL has two main thrusts that will be discussed in this talk. One is the generation of 3D models of the in-situ environment, in particular the merging of models from different sensors, different modes (orbital, descent, and lander), and even different missions. The other is the use of various tools to visualize the environment within which the rover will be operating to maximize the understanding by the operator. A suite of tools is under development which provide an integrated view into the environment while providing a variety of modes of visualization. This allows the operator to smoothly switch from one mode to another depending on the information and presentation desired.

  16. Essays in energy, environment and technological change (United States)

    Zhou, Yichen Christy

    This dissertation studies technological change in the context of energy and environmental economics. Technology plays a key role in reducing greenhouse gas emissions from the transportation sector. Chapter 1 estimates a structural model of the car industry that allows for endogenous product characteristics to investigate how gasoline taxes, R&D subsidies and competition affect fuel efficiency and vehicle prices in the medium-run, both through car-makers' decisions to adopt technologies and through their investments in knowledge capital. I use technology adoption and automotive patents data for 1986-2006 to estimate this model. I show that 92% of fuel efficiency improvements between 1986 and 2006 were driven by technology adoption, while the role of knowledge capital is largely to reduce the marginal production costs of fuel-efficient cars. A counterfactual predicts that an additional 1/gallon gasoline tax in 2006 would have increased the technology adoption rate, and raised average fuel efficiency by 0.47 miles/gallon, twice the annual fuel efficiency improvement in 2003-2006. An R&D subsidy that would reduce the marginal cost of knowledge capital by 25% in 2006 would have raised investment in knowledge capital. This subsidy would have raised fuel efficiency only by 0.06 miles/gallon in 2006, but would have increased variable profits by 2.3 billion over all firms that year. Passenger vehicle fuel economy standards in the United States will require substantial improvements in new vehicle fuel economy over the next decade. Economic theory suggests that vehicle manufacturers adopt greater fuel-saving technologies for vehicles with larger market size. Chapter 2 documents a strong connection between market size, measured by sales, and technology adoption. Using variation consumer demographics and purchasing pattern to account for the endogeneity of market size, we find that a 10 percent increase in market size raises vehicle fuel efficiency by 0.3 percent, as compared

  2. Perinatal outcomes of pregnancies conceived by assisted reproductive technologies

    Directory of Open Access Journals (Sweden)

    Šljivančanin Tamara


    Full Text Available Introduction. Recent epidemiological studies showed significantly higher incidence of perinatal complications in newborns and women after the use of assisted reproductive technologies (ART. Multiple pregnancies are more frequent after the use of ART. Singleton pregnancies following ART are more prone to preterm birth, low and very low birth weight (LBW and VLBW, small for gestational age (SGA and perinatal mortality. Objective. The aim of this study was to summarize the results of relevant articles and to evaluate whether the mode of conception is the determining factor for different pregnancy outcomes after assisted and natural conceptions. Methods. Eleven studies were included in this review. The following outcomes were observed: preterm and very preterm birth, SGA, LBW, VLBW, perinatal mortality, admission to neonatal intensive care unit (NICU, and Apgar score (As ≤7 at fifth minute. Qualitative analysis and quantitative assessment were performed. Results. For singletons, odds ratios were 1.794 (95% confidence interval 1.660-1.939 for preterm birth, 1.649 (1.301-2.089 for LBW, 1.265 (1.048-1.527 for SGA. Admission to NICU, As≤7 at fifth minute and perinatal mortality showed significantly different frequency after assisted conception. Summary of results for twin gestations showed no significant difference between ART and spontaneous conception for preterm birth (32-36 weeks, very preterm birth (<32 weeks, LBW and VLBW. Conclusion. Analyzed studies showed that infants from ART have significantly worse perinatal outcome compared with natural conception. More observational studies should be conducted in order to establish the exact mechanism leading to more frequent perinatal morbidity and mortality after the use of ART.

  3. The thin endometrium in assisted reproductive technology: An ongoing challenge

    Directory of Open Access Journals (Sweden)

    Maryam Eftekhar


    Full Text Available Thin endometrium is identified to adversely affect reproductive success rates after assisted reproductive technology (ART. Several treatment modalities have been presented to patients with thin endometrium, to improve endometrial thickness and the subsequent endometrial receptivity. These approaches comprising hormonal management by estradiol, tamoxifen, human chorionic gonadotropin (hCG and gonadotropin-releasing hormone (GnRH agonist, vasoactive agents such as aspirin, vitamin E, pentoxifylline, nitroglycerin and sildenafil, intra-uterine infusion of growth factor such as Granulocyte Colony Stimulating Factor (G-CSF and the latest application of platelet-rich plasma, electrical stimulation, regenerative medicine and presentation of endometrial receptivity array. In spite of the large variety of treatment, most of the choices achieve only minor modification in the endometrium thickness and have not been validated so far. Treatment of thin endometrium remains a challenge and future enormous investigations are required to further clarification and ideal management of patients with thin endometrium.

  5. Gender, infertility, motherhood, and assisted reproductive technology (ART) in Turkey. (United States)

    Sahinoglu, Serap; Buken, Nuket Ornek


    In Turkey, as in many other countries, infertility is generally regarded as a negative phenomenon in a woman's life and is associated with a lot of stigma by society. In other words, female infertility and having a baby using Assisted Reproductive Technologies (ART) have to be taken into consideration with respect to gender motherhood, social factors, religion and law. Yet if a woman chooses to use ART she has to deal with the consequences of her decision, such as being ostracized by society. Other types of procedures in this area, such as sperm and ova donation or surrogate motherhood, are not permitted in law. However; both before and after the development of this techonology, society has been finding its own solutions which are rarely questioned and are still performed This article will discuss what these practices are and try to reach some pragmatic conclusions concerning female infertility, the concept of motherhood and some traditional practices in Turkey.

  6. Experience with ISO quality control in assisted reproductive technology. (United States)

    Alper, Michael M


    Assisted reproductive technology (ART) programs are complex organizations requiring the integration of multiple disciplines. ISO 9001:2008 is a quality management system that is readily adaptable to an ART program. The value that ISO brings to the entire organization includes control of documents, clear delineation of responsibilities of staff members, documentation of the numerous processes and procedures, improvement in tracking and reducing errors, and overall better control of systems. A quality ART program sets quality objectives and monitors their progress. ISO provides a sense of transparency within the organization and clearer understanding of how service is provided to patients. Most importantly, ISO provides the framework to allow for continual improvement. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

  7. Assisted reproductive technologies: professional and legal restrictions in Australian clinics. (United States)

    Petersen, Kerry; Baker, H W G; Pitts, Marian; Thorpe, Rachel


    The professional and legal regulation of assisted reproductive technologies (ART) in Australia is a vast maze of intersecting laws and guidelines which place restrictions on the provision of services such as infertility treatment, surrogacy, sex selection for social reasons, donor insemination, pre-implantation diagnosis and human embryo research. This study investigated the application of these restrictions on clinical practice in New South Wales, a relatively unregulated State, and Victoria, a relatively highly regulated State. The results of the survey indicate that the range of ART services in Victorian clinics was far more limited than in New South Wales clinics. The Victorian clinics uniformly restricted access of single and lesbian women and did not offer social sex selection procedures. The New South Wales clinics adopted different polices regarding these services. It was found that restrictive laws governing "social" issues have a significant impact on the availability of ART services and some respondents seemed unclear about the nature of restrictions and laws relevant to their work. It was also found that "reproductive tourism" is prevalent and restrictions were circumnavigated by patients with assistance from clinics. It was concluded that more evidence is required to evaluate regulation in this field of medicine.

  8. The process of justifying assisted reproductive technologies in Iran. (United States)

    Gooshki, Ehsan Shamsi; Allahbedashti, Neda


    Infertility is medically defined as one year of unprotected intercourse that does not result in pregnancy. Infertility is a noticeable medical problem in Iran, and about a quarter of Iranian couples experience primary infertility at some point in their lives. Since having children is a basic social value in Iran, infertility has an adverse effect on the health of the couple and affects their well-being. The various methods of assisting infertile couples raise several ethical questions and touch upon certain sensitive points. Although the present Iranian legislative system, which is based on the Shi'a school of Islam, has legalised some aspects of assisted reproductive technologies (ARTs), given the absence of a general officially ratified act (official pathway), such medical interventions are usually justified through a fatwa system (non-official pathway). Officially registered married couples can access almost all ART methods, including third-party gamete donation, if they use such pathways. The process of justifying ART interventions generally began when in vitro fertilisation was given the nod and later, Ayatollah Khamenei (the political-religious leader of the country) issued a fatwa which permitted gamete donation by third parties. This open juristic approach paved the way for the ratification of the Embryo Donation to Infertile Spouses Act in 2003.

  9. Atmospheric Sounder Spectrometer for Infrared Spectral Technology (ASSIST) Instrument Handbook

    Energy Technology Data Exchange (ETDEWEB)

    Flynn, Connor J. [Pacific Northwest National Lab. (PNNL), Richland, WA (United States). Atmospheric Radiation Measurement (ARM) Program


    The Atmospheric Sounder Spectrometer for Infrared Spectral Technology (ASSIST) measures the absolute infrared (IR) spectral radiance (watts per square meter per steradian per wavenumber) of the sky directly above the instrument. More information about the instrument can be found through the manufacturer’s website. The spectral measurement range of the instrument is 3300 to 520 wavenumbers (cm-1) or 3-19.2 microns for the normal-range instruments and 3300 to 400 cm-1 or 3-25 microns, for the extended-range polar instruments. Spectral resolution is 1.0 cm-1. Instrument field-of-view is 1.3 degrees. Calibrated sky radiance spectra are produced on cycle of about 141 seconds with a group of 6 radiance spectra zenith having dwell times of about 14 seconds each interspersed with 55 seconds of calibration and mirror motion. The ASSIST data is comparable to the Atmospheric Emitted Radiance Interferometer (AERI) data and can be used for 1) evaluating line-by-line radiative transport codes, 2) detecting/quantifying cloud effects on ground-based measurements of infrared spectral radiance (and hence is valuable for cloud property retrievals), and 3) calculating vertical atmospheric profiles of temperature and water vapor and the detection of trace gases.

  12. Assistive technology for children and young people with low vision. (United States)

    Thomas, Rachel; Barker, Lucy; Rubin, Gary; Dahlmann-Noor, Annegret


    Recent technological developments, such as the near universal spread of mobile phones and portable computers and improvements in the accessibility features of these devices, give children and young people with low vision greater independent access to information. Some electronic technologies, such as closed circuit TV, are well established low vision aids and newer versions, such as electronic readers or off-the shelf tablet computers, may offer similar functionalities with easier portability and at lower cost. To assess the effect of electronic assistive technologies on reading, educational outcomes and quality of life in children and young people with low vision.

    International Nuclear Information System (INIS)

    Kawasaki, M.


    The current state of Japanese science and technology policy is discussed within the framework of overall global environmental policy. Principles of Japanese environmental policy include participation in international schemes for conservation of the global environment, promotion of Japanese research on the global environment, development and diffusion of technologies contributing to conservation of the global environment, contribution to conservation of the environment in developing countries, and maintenance of economic and social activities in Japan at an environmentally beneficial level. The Japanese environmental budget includes expenditures for earth observation and monitoring by satellite, energy-related research and development, and control of greenhouse gas emissions. The proportion of overall Japanese research and development (R ampersand D) expenditures which were spent on the global environment was about 2% in 1991. Of governmental research expenditures, ca 22% involve the global environment; however, some part of the expenditures on energy R ampersand D and on earth observation satellite R ampersand D are also environment-related. 5 figs

  15. A technology roadmap of assistive technologies for dementia care in Japan. (United States)

    Sugihara, Taro; Fujinami, Tsutomu; Phaal, Robert; Ikawa, Yasuo


    The number of elderly people in Japan is growing, which raises the issue of dementia, as the probability of becoming cognitively impaired increases with age. There is an increasing need for caregivers, who are well-trained, experienced and can pay special attention to the needs of people with dementia. Technology can play an important role in helping such people and their caregivers. A lack of mutual understanding between caregivers and researchers regarding the appropriate uses of assistive technologies is another problem. A vision of person-centred care based on the use of information and communication technology to maintain residents' autonomy and continuity in their lives is presented. Based on this vision, a roadmap and a list of challenges to realizing assistive technologies have been developed. The roadmap facilitates mutual understanding between caregivers and researchers, resulting in appropriate technologies to enhance the quality of life of people with dementia. © The Author(s) 2013 Reprints and permissions:

  17. Technology and active agency of older adults living in service house environment. (United States)

    Sallinen, Merja; Hentonen, Outi; Kärki, Anne


    The purpose of the study was to explore whether or not the assistive and safety technology that is currently used in service house environment supports the active agency of the elderly residents. Twelve purposively chosen elderly residents were interviewed. The data were analyzed by theory-driven content analysis using the modalities of the agency-model as a theoretical frame. The technological devices and systems partially support the active agency of the residents. Deterioration of their functioning seems to limit the use of devices as well as complicate their learning on how to use these systems. The respondents had only few insights of the possibilities that this technology could offer to them in their daily life and they were not expecting their functioning to improve in the future. The homeliness and intimacy of the environment was highly appreciated. Although the attitude towards technology was, in general, reserved, technology was seen as one possibility to support active agency. The current technologies seem to be designed from the needs of the organization and not from the needs of the residents. In the future, more emphasis needs to be put on designing individualized devices in cooperation with the users. Implications for Rehabilitation To support independence, autonomy and active agency of the older adults, the technological solutions must be based on perceived needs of the individual and the design should be adaptable to the functional limitations one has. Nursing staff's knowledge about assistive devices and technologies need to be updated on regular bases in order to be able to recommend appropriate devices for the elderly. Taking into account the fact that many older adults have mild to moderate memory problems as well as difficulties with vision and hearing, more attention needs to be paid to didactics, i.e. how the introduction and guidance of the use of new technologies, assistive devices or safety systems is best done with them.

  19. Pediatric physical therapists' perceptions of their training in assistive technology. (United States)

    Long, Toby M; Perry, Deborah F


    Availability of assistive technology (AT) and federal legislation promoting greater use of AT for children with disabilities have increased substantially. The purpose of this study was to determine the perceived adequacy of previous training in AT, specific training needs, preferred methods of training, and the confidence level of pediatric physical therapists in providing AT. Three hundred eighty pediatric physical therapists responded to a survey questionnaire mailed to a random sample of members of the Section on Pediatrics of the American Physical Therapy Association. The survey was used to determine training needs of therapists in the area of AT, their confidence in delivering AT services, preferred methods of training, and challenges in becoming trained. The therapists reported having less-than-adequate training in AT and a lack of confidence in delivering AT services. They also reported that they would like accessible and affordable training that focuses on funding technology and services, knowledge of specific devices, and assessment and evaluation methods. The findings underscore the need to develop pre-service, in-service, and continuing education training opportunities in AT for providers working with children who have disabilities.

  20. The impact of mobility assistive technology devices on participation for individuals with disabilities. (United States)

    Carver, Jordan; Ganus, Ashley; Ivey, Jon Mark; Plummer, Teresa; Eubank, Ann


    This study aims to address the gap in research and contribute to the body of knowledge on the perspectives assistive technology device users have toward their devices. Mixed methods were used to better understand the impact of mobility assistive technology devices (MATDs) on participation for individuals with disabilities. The Functional Mobility Assessment was administered in conjunction with two qualitative questions developed by the research team allowing participants to expound on the impact of their MATD experience. Participants were recruited online via the National Spinal Cord Injury Association website and in-person at Abilities Expo in Atlanta, Georgia, and the International Seating Symposium in Nashville, Tennessee. Results are consistent with findings from prior research regarding accessibility for individuals with disabilities. Corresponding findings were found in both the quantitative and qualitative data and are categorized into several major themes: environment (indoor and outdoor), surface heights, transportation, dependence, independence, quality of life and participation. Quantitative data from this study indicate that users of MATD are satisfied with the way in which their devices enable maneuvering indoors, while qualitative data suggest otherwise. Implications for healthcare practitioners are described and future recommendations are provided. Implications for Rehabilitation Healthcare professionals should advocate for proper mobility assistive technology devices (MATDs) for their patients in order to enable increased independence, safety and efficiency. Healthcare professionals must be cognizant of the impact of the environment and/or environmental barriers when prescribing MATD. Additional areas of interest for future research may include investigating the impact of MATD in association with date of onset of disability, according to diagnoses, or specific to length of time since acquiring the device.

  1. Non-invasive brain-computer interface system: towards its application as assistive technology. (United States)

    Cincotti, Febo; Mattia, Donatella; Aloise, Fabio; Bufalari, Simona; Schalk, Gerwin; Oriolo, Giuseppe; Cherubini, Andrea; Marciani, Maria Grazia; Babiloni, Fabio


    The quality of life of people suffering from severe motor disabilities can benefit from the use of current assistive technology capable of ameliorating communication, house-environment management and mobility, according to the user's residual motor abilities. Brain-computer interfaces (BCIs) are systems that can translate brain activity into signals that control external devices. Thus they can represent the only technology for severely paralyzed patients to increase or maintain their communication and control options. Here we report on a pilot study in which a system was implemented and validated to allow disabled persons to improve or recover their mobility (directly or by emulation) and communication within the surrounding environment. The system is based on a software controller that offers to the user a communication interface that is matched with the individual's residual motor abilities. Patients (n=14) with severe motor disabilities due to progressive neurodegenerative disorders were trained to use the system prototype under a rehabilitation program carried out in a house-like furnished space. All users utilized regular assistive control options (e.g., microswitches or head trackers). In addition, four subjects learned to operate the system by means of a non-invasive EEG-based BCI. This system was controlled by the subjects' voluntary modulations of EEG sensorimotor rhythms recorded on the scalp; this skill was learnt even though the subjects have not had control over their limbs for a long time. We conclude that such a prototype system, which integrates several different assistive technologies including a BCI system, can potentially facilitate the translation from pre-clinical demonstrations to a clinical useful BCI.

    The imminent decline of the world's oil production, its high market prices and environmental impacts have made the production of biofuels to reach unprecedent volumes over the last 10 years. This is why there have been intense debates among international organizations and political leaders in order to discuss the impacts of the biofuel use intensification. Besides assessing the causes of the rise in the demand and production of biofuels, this paper also shows the state of the art of their world's current production. It is also discussed different vegetable raw materials sources and technological paths to produce biofuels, as well as issues regarding production cost and the relation of their economic feasibility with oil international prices. The environmental impacts of programs that encourage biofuel production, farmland land requirements and the impacts on food production are also discussed, considering the life cycle analysis (LCA) as a tool. It is concluded that the rise in the use of biofuels is inevitable and that international cooperation, regulations and certification mechanisms must be established regarding the use of land, the mitigation of environmental and social impacts caused by biofuel production. It is also mandatory to establish appropriate working conditions and decent remuneration for workers of the biofuels production chain. (author)

    Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and fertility clinics. This article intended to report the status of ART in 2009 Korean Society of Obstetrics and Gynecology surveyed. The current survey was performed to assess the status and success rate of ART performed in Korea, between January 1 and December 31, 2009. Reporting forms had been sent out to IVF centers via e-mail, and collected by e-mail as well in 2012. With International Committee Monitoring Assisted Reproductive Technologies recommendation, intracytoplasmic sperm injection (ICSI) and non-ICSI cases have been categorized and also IVF-ET cases involving frozen embryo replacement have been surveyed separately. Seventy-four centers have reported the treatment cycles initiated in the year of 2009, and had performed a total of 27,947 cycles of ART treatments. Among a total of 27,947 treatment cycles, IVF and ICSI cases added up to 22,049 (78.9%), with 45.3% IVF without ICSI and 54.7% IVF with ICSI, respectively. Among the IVF and ICSI patients, patients confirmed to have achieved clinical pregnancy was 28.8% per cycle with oocyte retrieval, and 30.9% per cycle with embryo transfer. The most common number of embryos transferred in 2009 is three embryos (40.4%), followed by 2 embryos (28.4%) and a single embryo transferred (13.6%). Among IVF and ICSI cycles that resulted in multiple live births, twin pregnancy rate was 45.3% and triple pregnancy rate was 1.1%. A total of 191 cases of oocyte donation had been performed to result in 25.0% of live birth rate. Meanwhile, a total of 5,619 cases of frozen embryo replacement had been performed with 33.7% of clinical

    technologies that have the potential to improve efficiency of livestock production. The focus will be on technologies that manipulate male and female gametes as well as the stem cells from which they are derived and the preimplantation embryo. While technology is crucial to other interventions in the reproductive process like control of seasonal breeding, hormonal regulation of ovulation, estrous cyclicity and pregnancy establishment, feeding to optimize reproduction, minimizing environmental stress, and selection of genes controlling reproduction, these will not be considered here. Rather the reader is directed to other chapters in this volume as well as some reviews on other aspects of artificial manipulation of reproduction (Reprod Fertil Dev 24:258-266, 2011; Reprod Domest Anim 43:40-47, 2008; Reprod Domest Anim 43:122-128, 2008; Soc Reprod Fertil Suppl 66:87-102, 2009; Comprehensive biotechnology, Amsterdam, pp 477-485; Dairy production medicine, Chichester, pp 153-163; Theriogenology 76:1619-1631, 2011; Theriogenology 76:1568-1582, 2011; Theriogenology 77:1-11, 2012). Given the large number of mammalian species used for production of products useful for man and the diversity in their biology and management, the review will not be comprehensive but instead will use results from species that are most illustrative of the opportunities generated by assisted reproductive technologies.

  10. Appropriating Technologies for Contextual Knowledge: Mobile Personal Learning Environments (United States)

    Attwell, Graham; Cook, John; Ravenscroft, Andrew

    The development of Technology Enhanced Learning has been dominated by the education paradigm. However social software and new forms of knowledge development and collaborative meaning making are challenging such domination. Technology is increasingly being used to mediate the development of work process knowledge and these processes are leading to the evolution of rhizomatic forms of community based knowledge development. Technologies can support different forms of contextual knowledge development through Personal Learning Environments. The appropriation or shaping of technologies to develop Personal Learning Environments may be seen as an outcome of learning in itself. Mobile devices have the potential to support situated and context based learning, as exemplified in projects undertaken at London Metropolitan University. This work provides the basis for the development of a Work Orientated MoBile Learning Environment (WOMBLE).

  11. A quality-of-life scale for assistive technology: results of a pilot study of aging and technology. (United States)

    Agree, Emily M; Freedman, Vicki A


    In an aging society, it is increasingly important to understand how assistive devices can be used by older people to maintain quality of life despite chronic disabilities. Assistive technology is a mainstay of physical therapist practice, but the potential for device use to affect psychosocial well-being is not yet understood at the population level. The objective of this study was to develop a parsimonious indicator that can be used in population-based surveys to represent the effect of assistive technologies on quality of life for older people, separate from personal assistance. This study was a cross-sectional survey. /b> The methods used in this study were psychometric scale development and structural equation modeling. The results indicated that a parsimonious, valid, and reliable scale reflecting quality of life related to assistive device use can be created from 3 questions designed to measure improvements in safety, control, and participation due to technology. The findings also suggested that assistive technology may more effectively improve quality of life for people with greater levels of functional limitations. The data were derived from a cross-sectional survey conducted by telephone. The use of personal assistance, on average, was low; thus, the applicability to a population with more profound care needs has yet to be confirmed. Determining the broader impact of assistive technology on quality of life with population-level measures may provide insight into how best to leverage technologies to prevent dependence in aging adults.

  12. Signals of opportunity assisted ubiquitous geolocation and navigation technology (United States)

    Tian, Hui; Mok, Esmond; Xia, Linyuan; Wu, Zhongyi


    The desire of geolocation and navigation technologies that provide precise, fast and reliable geo-services has exploded in the recent years, and there is a dramatic increase in the geo-service market varies from mass market applications to the new and innovative applications. The lack of reliable GNSS signals in the NLOS environment confronts many innovative ideas related to mass market location-based applications. But there is an optimized way to provide the ubiquitous geolocation services via exploitation of signals of opportunity (SoOP). The core concept of ubiquitous geolocation and navigation is provide globally available geo-services by giving the mobile terminal the ability to acquire their location information, this technology can be applied at all scales geo-reference by sharing some simple, inexpensive, robust geolocation and navigation algorisms for different technology such as GNSS and other emerging technology, and the goals of the ubiquitous geolocation and navigation service are reliable availability, transparency, seamlessness, awareness, and trustworthiness. SoOP are primarily envisioned to be man-made radio emitters not originally intended for geolocation and navigation, but may be extended to active beacons purposely deployed in an emergency situation, in this paper, we also regarded the signals of different wireless network those defined by the IEEE 802.11, IEEE 802.15 and IEEE 802.16 as an important part of SoOP. The use of widely available, powerful, and economically important SoOP in Hong Kong will provide a robust geolocation and navigation capability. We made some initial investigation into the use of the SoOP through feasibility studies and prototype investigations of the use of wireless local area network (WLAN), ultra-wide band (UWB) and ZigBee.

  15. Flexible and Affordable Foreign Language Learning Environment based on Web 2.0 Technologies

    Directory of Open Access Journals (Sweden)

    Christian Guetl


    Full Text Available Web technologies and educational platforms have greatly evolved over the past decade. One of the most significant factors contributing to education on the Internet has been the development of Web 2.0 technologies. These technologies, socially interactive in nature, have much to contribute to the area of Computer Assisted Language Leaning. Unfortunately, Web 2.0 technologies for the most part have been used in an ad hoc manner, permitting language learners acquire knowledge through interaction, but not through a more structured manner as these technologies were not developed to help lean languages as such. The goal of our work is to research and develop an environment, which employs Web 2.0 technology plus online language learning tools to provide a more integrated language learning environment. This paper will explore the technologies and provide information about how tools can be better integrated to provide a more productive working environment for language learners. A first working proof of concept based on our approach introduced is promising supporting modern language requirements and first findings and space for improvements are discussed.

  16. Standardization of green building technologies for environment design

    Directory of Open Access Journals (Sweden)

    Benuzh Andrey


    Full Text Available The article describes the structure and field of standardization ISO / TC 205 “Building environment design”, provides examples of green building technologies. The main purpose of the article is to show the interaction between international ISO / TC 205 “Building environment design” and created in Russia in 2016 the Technical Committee of Standardization № 366 “Green technology of the build environment and green innovative products”. Both of these technical committees promote green building technologies for environment design, thereby deal with the negative impact on the environment and the reasons of global warming. Instead of buildings that attempt to suppress and overcome nature, why not design buildings that integrate with the environment, on every possible level? The international standardization work which ISO/TC 205 “Building environment design” performs seeks, in addition to lowering trade barriers for engineering design, to promote and facilitate the design of high performance buildings: higher performing as economic assets for their owners, higher performing as buildings that provide amenable indoor environment for their occupants, and higher performing with respect to resource utilization and environmental impact.

  17. Assisted reproductive technologies: medical safety issues in the older woman. (United States)

    Segev, Yakir; Riskin-Mashiah, Shlomit; Lavie, Ofer; Auslender, Ron


    Abstract Previous study has shown that in the United States, most maternal deaths and severe obstetric complications due to chronic disease are potentially preventable through improved medical care before conception. Many women who need assisted reproductive technology (ART) because of infertility are older than the average pregnant woman. Risks for such chronic diseases as obesity, diabetes mellitus, chronic hypertension, cardiovascular disease (CVD), and malignancy greatly increase with maternal age. Chronic illness increases the risk of the in vitro fertilization (IVF) procedure and is also associated with increased obstetric risk and even death. The objective of this review is to outline the potential risks for older women who undergo ART procedures and pregnancy and to characterize guidelines for evaluation before enrollment in ART programs. A PubMed search revealed that very few studies have related to pre-ART medical evaluation. Therefore, we suggest a pre-ART medical assessment, comparable to the recommendations of the American Heart Association before noncompetitive physical activity and the American Society of Anesthesiologists before elective surgery. This assessment should include a thorough medical questionnaire and medical examination. Further evaluation and treatment should follow to ensure the safety of ART procedures and of ensuing pregnancies.


    Aleksanyan, A


    When pregnancy occurs as a result of assisted reproductive technologies (ART), there are more chances of developing complications and adverse outcomes for the mother and fetus compared to spontaneous pregnancies. Taking into account the noted features, the purpose of our study was to determine the nature of the complications of induced pregnancy and their frequency, depending on the causes of infertility. Under our supervision were 86 women with induced single-pregnancy. Two clinical groups were formed depending on the causes of infertility: group I was represented by 53 observations, in which infertility of endocrine genesis took place; Group II included 33 women with tubal peritoneal infertility. Pregnancy, resulting from ART, should be attributed to the group at high risk of complications of pregnancy. Among the causes of female infertility, the tubal peritoneal factor is the least dangerous in terms of the complicated course of the gestational process, and the endocrine factors that can cause a two-fold increase in the frequency of the threat of abortion and pre-eclampsia are more dangerous. In turn, the cause of endocrine infertility are various factors that need to be determined when predicting the course of induced pregnancy. A special feature of maintaining this category of pregnant women is the constant observation and correction of dyshormonal disorders, which not only cause anovulation, but can also negatively affect the course of pregnancy.

  19. Assisted reproductive technologies and equity of access issues. (United States)

    Peterson, M M


    In Australia and other countries, certain groups of women have traditionally been denied access to assisted reproductive technologies (ARTs). These typically are single heterosexual women, lesbians, poor women, and those whose ability to rear children is questioned, particularly women with certain disabilities or who are older. The arguments used to justify selection of women for ARTs are most often based on issues such as scarcity of resources, and absence of infertility (in lesbians and single women), or on social concerns: that it "goes against nature"; particular women might not make good mothers; unconventional families are not socially acceptable; or that children of older mothers might be orphaned at an early age. The social, medical, legal, and ethical reasoning that has traditionally promoted this lack of equity in access to ARTs, and whether the criteria used for client deselection are ethically appropriate in any particular case, are explored by this review. In addition, the issues of distribution and just "gatekeeping" practices associated with these sensitive medical services are examined.

  20. Passive wireless tags for tongue controlled assistive technology interfaces (United States)

    Rakibet, Osman O.; Horne, Robert J.; Kelly, Stephen W.


    Tongue control with low profile, passive mouth tags is demonstrated as a human–device interface by communicating values of tongue-tag separation over a wireless link. Confusion matrices are provided to demonstrate user accuracy in targeting by tongue position. Accuracy is found to increase dramatically after short training sequences with errors falling close to 1% in magnitude with zero missed targets. The rate at which users are able to learn accurate targeting with high accuracy indicates that this is an intuitive device to operate. The significance of the work is that innovative very unobtrusive, wireless tags can be used to provide intuitive human–computer interfaces based on low cost and disposable mouth mounted technology. With the development of an appropriate reading system, control of assistive devices such as computer mice or wheelchairs could be possible for tetraplegics and others who retain fine motor control capability of their tongues. The tags contain no battery and are intended to fit directly on the hard palate, detecting tongue position in the mouth with no need for tongue piercings. PMID:27222736

  1. Effects of Assisted Reproduction Technology on Placental Imprinted Gene Expression (United States)

    Katagiri, Yukiko; Aoki, Chizu; Tamaki-Ishihara, Yuko; Fukuda, Yusuke; Kitamura, Mamoru; Matsue, Yoichi; So, Akiko; Morita, Mineto


    We used placental tissue to compare the imprinted gene expression of IGF2, H19, KCNQ1OT1, and CDKN1C of singletons conceived via assisted reproduction technology (ART) with that of spontaneously conceived (SC) singletons. Of 989 singletons examined (ART n = 65; SC n = 924), neonatal weight was significantly lower (P < .001) in the ART group than in the SC group, but placental weight showed no significant difference. Gene expression analyzed by real-time PCR was similar for both groups with appropriate-for-date (AFD) birth weight. H19 expression was suppressed in fetal growth retardation (FGR) cases in the ART and SC groups compared with AFD cases (P < .02 and P < .05, resp.). In contrast, CDKN1C expression was suppressed in FGR cases in the ART group (P < .01), while KCNQ1OT1 expression was hyperexpressed in FGR cases in the SC group (P < .05). As imprinted gene expression patterns differed between the ART and SC groups, we speculate that ART modifies epigenetic status even though the possibilities always exist. PMID:20706653

  2. Outcome of assisted reproductive technology in overweight and obese women (United States)

    MacKenna, Antonio; Schwarze, Juan Enrique; Crosby, Javier A; Zegers-Hochschild, Fernando


    Objective The main objective of this study was to assess the prevalence of overweight and obesity among patients undergoing assisted reproductive technology (ART) in Latin America and its consequences on treatment outcomes. Methods We used the Latin American Registry of ART to obtain women's age and body mass index (BMI), cancellation rate, number of oocytes retrieved and embryos transferred, clinical pregnancy, live birth and miscarriage rates from 107.313 patients undergoing autologous IVF and ICSI during four years; a multivariable analysis was performed to determine the effect of BMI on cancellation, oocytes retrieved, pregnancy, live birth and miscarriage, adjusting for age, number of embryos transferred and embryo developmental stage upon embryo transfer, when appropriate. Results The prevalence of overweight and obesity was 16.1% and 42.4%, respectively; correcting for age of female partner, overweight and obesity were associated to an increase in the odds of cancellation and to a lower mean number of oocytes retrieved; after adjusting for age, number of embryos transferred and stage of embryo development at transfer, we found that the BMI category was not associated to a change in the likelihoods of pregnancy, live birth and miscarriage. Conclusions The prevalence of obesity among women seeking ART in Latin America is surprisingly high; however, BMI does not influence the outcome of ART performed in these women. PMID:28609272

    Full Text Available Purpose: This study was performed to investigate the incidence of thrombophilic gene mutations in repeated assisted reproductive technology (ART failures. Methods: The prevalence of mutated genes in the patients with a history of three or more previous ART failures was compared with the patients with a history of successful pregnancy following ARTs. The study group included 70 patients, 34 with three or more previously failed ARTs (A and control group consisted of 36 patients with successful pregnancy following ARTs (B. All patients were tested for the presence of mutated thrombophilic genes including factor V Leiden (FVL, Methylenetetrahydrofolate reductase (MTHFR and Prothrombin (G20210A using real-time polymerase chain reaction (RT- PCR. Results: Mutation of FVL gene was detected in 5.9% women of group A (2 of 34 compared with 2.8% women (1 of 36 of control group (P = 0.6. Mutation of MTHFR gene was found in 35.3% (12 cases as compared with 50% (18 cases of control (35.3% versus 50%; P = 0.23. Regarding Prothrombin, only control group had 5.6% mutation (P = 0.49. No significant differences were detected in the incidences of FVL, Prothrombin and MTHFR in the study group A compared with the control group B. Conclusion: The obtained results suggest that thrombophilia does not have a significant effect in ART failures.

    Jafarzadehpur, Ebrahim; Kermani, Ramin Mozafari; Mohhamadi, Ali Reza; Nateghi, Mohammad Reza; Fazeli, Abolhasan Shahzade; Kashi, Khashayar Mehdizadeh


    Nowadays, many infertile couples can have child by assistant reproductive technology (ART). Always the undesirable effects of these methods on newborn are considered and are evaluated. The aim of this study is to describe the impact of ART on ocular and visual performances of infants born by these methods. In a cross-sectional descriptive study, 479 infants aged three-nine months presented to an optometry clinic of Child Health and Development Research Department (CHDRD), Tehran, Iran. Static retinoscopy, qualitative fixation evaluation, Hirschberg test, red reflex assessment and external eye examination were carried out. Other information such as birth weight and maturity of the infants was recorded. It was possible to assess only 320 out of 479 infants due to general condition of some participants. Comparison of mean refractive error in infants' right and left eyes did not show any significant difference. Our findings confirmed that 20.3% had poor fixation, while 2.9% revealed manifest strabismus. The results also revealed the prevalences of myopia, hyperopia and emmetropia are 2.9%, 87%, and 10.1%, respectively. Red reflex abnormalities were significantly found in boys and in preterm infants (p ART, especially for premature male ART infants. These results also suggest the probability of fixation condition and visual deficiencies in these infants. It is recommended to pay close attention to this preliminary report about the refractive and fixation condition of the infants born after ART.

    Liu, Shan; Shi, Lin; Shi, Juanzi


    The impact of endometrial cavity fluid (ECF) on assisted reproductive technology (ART) outcomes has not been evaluated in a meta-analysis. To evaluate the impact of ECF on the outcome of ART cycles. PubMed, China Academic Journals Full-text Database, and China Doctoral/Masters Dissertations Full-text Databases were searched for reports published in any language before January 1, 2015, using relevant keywords. Studies were included if they compared the outcome of ART in women with and without ECF. Background information, participants' characteristics, and study outcomes were recorded. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using the Mantel-Haenszel method. Six studies evaluating 5928 ART cycles were included. The pregnancy rate was significantly lower in the group with ECF than in the group without ECF (OR 0.74, 95% CI 0.55-0.98; P=0.03). The same association was observed if the analysis included only patients with hydrosalpinx (OR 0.36, 95% CI 0.15-0.86; P=0.02). The clinical pregnancy rate after ART is significantly lower among patients with ECF than among those without ECF. In addition, if ECF is found in patients with hydrosalpinx, ART cycles should be cancelled after oocyte retrieval. Copyright © 2015 International Federation of Gynecology and Obstetrics.

  6. Assisted reproductive technology in China: compliance and non-compliance. (United States)

    Qiao, Jie; Feng, Huai L


    According to the WHO, infertility and sterility will be the third-most serious disease worldwide in the 21st century, after cancer and cardiovascular diseases. In contrast to developed countries, assisted reproductive technology (ART) were not offered in China until the mid-1980s with the first in vitro fertilization (IVF) infant born in Taiwan in 1985, then Hong Kong in 1986, and mainland China in 1988, respectively. Since those inceptions, the practice of ART in China has evoked a variety of social, cultural, political and one-child policy responses that have resulted in restrictions on the number of IVF cycles performed annually. According to recent survey, an estimate 40-50 million women and 45 million men suffered from infertility, which is estimated that more than ten million Chinese infertile couples require ART treatment. However, it has limited access to ART facilities, many of them may not have a child are whirling to all types of fertility therapies. Exposure to radiation, pesticides and other environmental pollutants, work-related stress and unhealthy lifestyles are believed to contribute to the increasing incidence of infertility in China. The aim of this first report is to provide China nationwide ART data and government policy in compliance and 
non-compliance, particularly related to family plan policy in China.

  7. Risk of peripartum hysterectomy in births after assisted reproductive technology. (United States)

    Cromi, Antonella; Candeloro, Ilario; Marconi, Nicola; Casarin, Jvan; Serati, Maurizio; Agosti, Massimo; Ghezzi, Fabio


    To investigate whether women who conceive after assisted reproductive technology (ART) are at higher risk for emergency peripartum hysterectomy. A case-control study using a prospectively maintained institutional database. A tertiary referral university teaching maternity hospital. Thirty-one women who underwent peripartum hysterectomy for management of hemorrhage, and 19,902 control women. None. Association between potential predictors and peripartum hysterectomy. The incidence of peripartum hysterectomy was 1.7 cases per 1,000 births (95% confidence interval [CI] 1.2-2.4). After adjustment for maternal age and twin pregnancy, placenta previa (odds ratio [OR] 50.78, 95% CI 23.30-110.68), prior cesarean delivery (OR 6.72, 95% CI 2.99-15.09 for one cesarean; OR 6.80, 95% CI 1.45-31.90 for two or more cesareans), previous myomectomy (OR 24.59, 95% CI 6.70-90.19), and ART conception (OR 5.98, 95% CI 2.18-16.40) were all antenatal predictors for peripartum hysterectomy. In women having a peripartum hysterectomy, 13.4% of the risk is attributable to mode of conception. A history of ART increases the likelihood of needing a peripartum hysterectomy to control hemorrhage. Further investigation is needed to determine whether ART conception should be included in algorithms of risk stratification for emergency cesarean hysterectomy and plan of care be modified accordingly.

  8. Best practices for team-based assistive technology design courses. (United States)

    Goldberg, Mary R; Pearlman, Jonathan L


    Team-based design courses focused on products for people with disabilities have become relatively common, in part because of training grants such as the NSF Research to Aid Persons with Disabilities course grants. An output from these courses is an annual description of courses and projects but has yet to be complied into a "best practices guide," though it could be helpful for instructors. To meet this need, we conducted a study to generate best practices for assistive technology product development courses and how to use these courses to teach students the fundamentals of innovation. A full list of recommendations is comprised in the manuscript and include identifying a client through a reliable clinical partner; allowing for transparency between the instructors, the client, and the team(s); establishing multi-disciplinary teams; using a process-oriented vs. solution-oriented product development model; using a project management software to facilitate and archive communication and outputs; facilitating client interaction through frequent communication; seeking to develop professional role confidence to inspire students' commitment to engineering and (where applicable) rehabilitation field; publishing student designs on repositories; incorporating both formal and informal education opportunities related to design; and encouraging students to submit their designs to local or national entrepreneurship competitions.

    Directory of Open Access Journals (Sweden)

    Cui Hong Zheng


    Full Text Available The aim of this paper was to provide reliable evidence by performing a systematic review and meta-analysis for evaluating the role of acupuncture in assisted reproductive technology. All randomized controlled trials that evaluated the effects of acupuncture, including manual, electrical, and laser acupuncture (LA techniques, on the clinical pregnancy rate (CPR and live birth rate (LBR of in vitro fertilization (IVF or artificial insemination were included. The controlled groups consisted of no acupuncture and sham acupuncture groups. The sham acupuncture included sham acupuncture at acupoints, sham acupuncture at non- or inappropriate points, sham LA, and adhesive tapes. Twenty-three trials (a total of 5598 participants were included in this paper. The pooled CPR from all acupuncture groups was significantly higher than that from all controlled groups, whereas the LBR was not significantly different between the two groups. However, the results were quite distinct when the type of control and/or different acupuncture times were examined in a sensitivity analysis. The results mainly indicate that acupuncture, especially around the time of the controlled ovarian hyperstimulation, improves pregnancy outcomes in women undergoing IVF. More positive effects from acupuncture in IVF can be expected if a more individualized acupuncture programs are used.

  10. [Health and development of children conceived through assisted reproductive technologies]. (United States)

    Epelboin, Sylvie; Patrat, Catherine; Luton, Dominique


    Around 3% of children are conceived by assisted reproductive technology (ART) in France. Several questions concerning the early or late follow-up of these children are raised, as there are differences in the population in charge and because of clinical or biological procedures used. Nevertheless, one has to be cautious in interpreting the data as it is difficult to study one factor at a time, and as many other events can bias the results. However, ART is associated with a higher risk, even moderate, of prematurity, foetal hypotrophy, and neo natal complications, as compared to natural conceived children. There is also increasing evidence that ART-conceived children present more epigenetic diseases and congenital mainly concerning cardio-vascular, uro-genital and musculo-skeletal systems, as natural conceived children. Absolute risks remain anyway moderate and reassuring. Long term follow up is encouraging, with correct growth or psychomotor development of these children, and no significant excess of risk for cancer, but it is necessary to carry on this follow up in order to have data on their development to adulthood and on their fertility.

  11. An Exercise in Technology Prioritization in a Competitive Environment (United States)

    Stephens, Karen L.


    The proper prioritization of technologies within a technology development program is critical for success in a budget constrained environment. A large portfolio of diverse products at differing states of development all competing for program resources presents a need for a process by which a realistic need date can guide the development strategy for each technology. This paper will document an exercise to identify "mission pull" for each technology that can be used to identify the best projected need date for each. This date is then used to back out a development schedule with corresponding funding profile needed to meet the flight opportunity.

    Lobo Pereira Fernando


    Full Text Available Abstract Background The combination of robotic tools with assistance technology determines a slightly explored area of applications and advantages for disability or elder people in their daily tasks. Autonomous motorized wheelchair navigation inside an environment, behaviour based control of orthopaedic arms or user's preference learning from a friendly interface are some examples of this new field. In this paper, a Simultaneous Localization and Mapping (SLAM algorithm is implemented to allow the environmental learning by a mobile robot while its navigation is governed by electromyographic signals. The entire system is part autonomous and part user-decision dependent (semi-autonomous. The environmental learning executed by the SLAM algorithm and the low level behaviour-based reactions of the mobile robot are robotic autonomous tasks, whereas the mobile robot navigation inside an environment is commanded by a Muscle-Computer Interface (MCI. Methods In this paper, a sequential Extended Kalman Filter (EKF feature-based SLAM algorithm is implemented. The features correspond to lines and corners -concave and convex- of the environment. From the SLAM architecture, a global metric map of the environment is derived. The electromyographic signals that command the robot's movements can be adapted to the patient's disabilities. For mobile robot navigation purposes, five commands were obtained from the MCI: turn to the left, turn to the right, stop, start and exit. A kinematic controller to control the mobile robot was implemented. A low level behavior strategy was also implemented to avoid robot's collisions with the environment and moving agents. Results The entire system was tested in a population of seven volunteers: three elder, two below-elbow amputees and two young normally limbed patients. The experiments were performed within a closed low dynamic environment. Subjects took an average time of 35 minutes to navigate the environment and to learn how

    Full Text Available Geothermal energy is abundant everywhere in the world. It certainly would be a great benefit for human being once it is produced by a sophisticated technology. Consequently, it would be the biggest console for earth considering environmental sustainability. Unfortunately, the current status of commercial production of geothermal energy primarily from hydrothermal, geopressured, hot dry rock, and magma are limited to a few countries due to technological difficulties and production cost. This paper describes a simple technology where an in situ geothermal plant assisted by a heat pump would act as a high-temperature production (>150°C to provide excellent capacity of energy generation. The issue related to costs is interestingly cheaper on production, comparing to other technologies, such as solar, hydro, wind, and traditional geothermal technology as described in this article. Therefore, it is suggested that heat pump assisted in situ geothermal energy sources has a great potentiality to be a prime energy source in near future. Since the technology has a number of positive characteristics (simple, safe, and provides continuous baseload, load following, or peaking capacity and benign environmental attributes (zero emissions of CO2, SOx, and NOx, it certainly would be an interesting technology in both developed, and developing countries as an attractive option to produce clean energy to confirm a better environment.

    Full Text Available The world has entered the Knowledge Age. Information Technology is gradually turning the world into an Information Highway Network. The development of technology has greatly accelerated the international flow of information, capital and commodities and speeded the growth of economic integration. At the same time, the cycle of technological development and commercialization is becoming shorter and shorter [Zhouying, 1999]. Information technology is bringing rapid and profound changes to higher education, as it has to virtually every process in our society. Productivity often suffers because is difficult and timeconsuming to conduct a team effort. A portal solution base on SharePoint Portal Server can greatly facilitate the process of bringing knowledge teachers together as a team to achieve educational goals by providing a single point to access: automated essential day-to-day email communication, management of contacts, calendars, and instant messages, shared facilities to allow small teams of teachers to contribute to team and project-focused Web site, track tasks and events, shortened web-publishing cycles by linking collaboration and publishing processes.

    Full Text Available In exploratory interviews and unsystematic observations with professionals working in the field of rehabilitation of persons with disabilities, we observed that there is a lack of systematic development in the process of assistive technology resources, resulting in products with low quality of usability. The main objective of the present study was to contribute, through a methodological proposal, to the formation of occupational therapists in the process of developing objects for persons with disabilities. The methodology used was a brief review of the steps taken in this research. The survey was conducted and recorded relying on the following steps: literature review; organization of the research project; presentation of data from field research conducted with occupational therapists who produce objects of assistive technology; assessment and interview with users; application of questionnaires to teachers of assistive technology disciplines; interviews with occupational therapists who perform making assistive technology products to other professionals; proposal of a flowchart for the development of assistive technology resources.

  5. Effects of solar photovoltaic technology on the environment in China. (United States)

    Qi, Liqiang; Zhang, Yajuan


    Among the various types of renewable energy, solar photovoltaic has elicited the most attention because of its low pollution, abundant reserve, and endless supply. Solar photovoltaic technology generates both positive and negative effects on the environment. The environmental loss of 0.00666 yuan/kWh from solar photovoltaic technology is lower than that from coal-fired power generation (0.05216 yuan/kWh). The negative effects of solar photovoltaic system production include wastewater and waste gas pollutions, the representatives of which contain fluorine, chromium with wastewater and hydrogen fluoride, and silicon tetrachloride gas. Solar panels are also a source of light pollution. Improper disposal of solar cells that have reached the end of their service life harms the environment through the stench they produce and the damage they cause to the soil. So, the positive and negative effects of green energy photovoltaic power generation technology on the environment should be considered.

    Full Text Available It is intended to understand the perceptions of nurses about the computerization of the Nursing Care Systematization in a general clinical hospitalization unit of a hospital in Vale do Taquari / Rio Grande do Sul / Brazil. This is a field research, descriptive and exploratory, with a qualitative approach, performed with six nurses working in a unit of general clinical hospitalization. The data were collected through interviews during the month of February 2016 and analyzed through the Thematic Content Analysis. The results evidenced potentialities and weaknesses resulting from the process of implementation of computerized SAE in a hospital clinical hospitalization unit. The main benefits derived from the adhesion of computerization in the SAE process were related to the increase of the quality of the care offered in the institution, security in the patient records and facilities in the processes of communication between the multiprofessional team. Already, the main difficulties in the processes of adhesion and implantation of SAE with the help of information technology were related to the discomforts due to the new practical and scientific demands that the teams develop during their assistance, since, the professionals sometimes perceive this new process As exhausting and unnecessary. The computerization of the SAE in health institutions still constitutes a challenge to be overcome and adopted to the daily routine of nurses, mainly regarding the motivation of their teams aiming at their adherence.

  7. Percutaneous Ventricular Assist Devices: A Health Technology Assessment (United States)

    Lee, Christine; Djalalov, Sandjar; Xie, Xuanqian; Holubowich, Corinne


    Background Percutaneous coronary intervention (PCI)—using a catheter to place a stent to keep blood vessels open—is increasingly used for high-risk patients who cannot undergo surgery. Cardiogenic shock (when the heart suddenly cannot pump enough blood) is associated with a high mortality rate. The percutaneous ventricular assist device can help control blood pressure and increase blood flow in these high-risk conditions. This health technology assessment examined the benefits, harms, and budget impact of the Impella percutaneous ventricular assist device in high-risk PCI and cardiogenic shock. We also analyzed cost-effectiveness of the Impella device in high-risk PCI. Methods We performed a systematic search of the literature for studies examining the effects of the Impella percutaneous ventricular assist device in high-risk PCI and cardiogenic shock, and appraised the evidence according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group criteria, focusing on hemodynamic stability, mortality, major adverse cardiac events, bleeding, and vascular complications. We developed a Markov decision-analytical model to assess the cost- effectiveness of Impella devices versus intra-aortic balloon pumps (IABPs), calculated incremental cost-effectiveness ratios (ICERs) using a 10-year time horizon, and conducted sensitivity analyses to examine the robustness of the estimates. The economic model was conducted from the perspective of the Ontario Ministry of Health and Long-Term Care. Results Eighteen studies (one randomized controlled trial and 10 observational studies for high-risk PCI, and one randomized controlled trial and six observational studies for cardiogenic shock) were included in the clinical review. Compared with IABPs, Impella 2.5, one model of the device, improved hemodynamic parameters (GRADE low–very low) but showed no significant difference in mortality (GRADE low), major adverse cardiac events (GRADE low

    Research support for Virtual Environment technology development has been a part of NASA's human factors research program since 1985. Under the auspices of the Office of Aeronautics and Space Technology (OAST), initial funding was provided to the Aerospace Human Factors Research Division, Ames Research Center, which resulted in the origination of this technology. Since 1985, other Centers have begun using and developing this technology. At each research and space flight center, NASA missions have been major drivers of the technology. This White Paper was the joint effort of all the Centers which have been involved in the development of technology and its applications to their unique missions. Appendix A is the list of those who have worked to prepare the document, directed by Dr. Cynthia H. Null, Ames Research Center, and Dr. James P. Jenkins, NASA Headquarters. This White Paper describes the technology and its applications in NASA Centers (Chapters 1, 2 and 3), the potential roles it can take in NASA (Chapters 4 and 5), and a roadmap of the next 5 years (FY 1994-1998). The audience for this White Paper consists of managers, engineers, scientists and the general public with an interest in Virtual Environment technology. Those who read the paper will determine whether this roadmap, or others, are to be followed.

  11. Aneuploidy rates in failed pregnancies following assisted reproductive technology. (United States)

    Nayak, Shweta; Pavone, Mary Ellen; Milad, Magdy; Kazer, Ralph


    Approximately 10%-15% of clinically recognized pregnancies end with a first trimester loss. Cytogenetic analysis of products of conception (POC) has revealed that a large proportion of these spontaneous miscarriages are a result of chromosomal abnormalities. However, relatively few studies have evaluated chromosomal abnormalities in pregnancies achieved using assisted reproductive technologies (ART). Here, we review the incidence and type of chromosomal abnormalities that occurred in our infertility patient population undergoing ART and provide a review of the literature pertaining to this subject. A retrospective chart review of all patients from our medical center who conceived using ART between January 2000 and January 2008, who experienced a subsequent early pregnancy loss, and whose POCs were successfully karyotyped were included. We also conducted a literature review in PubMed, searching for other articles on this subject. Two hundred fourteen patients conceived with ART, experienced an early loss, and subsequently underwent a dilation and curettage (D&C) between 2000 and 2008. A total of 59 (27%) patients chose to have cytogenetic testing, and their POCs were successfully karyotyped. The overall rate of aneuploidy in this group was 83%. Our PubMed search revealed a total of 12 studies that were identified and evaluated and deemed appropriate for review. Consistent with most of the literature, we found a high rate of aneuploidy present in infertile patients conceiving using ART. Because an abnormal karyotype provides an explanation for an early loss, this and other studies seem to suggest that routinely carrying out this assessment in such patients may be of value.

  12. Regulatory framework in assisted reproductive technologies, relevance and main issues. (United States)

    Merlet, Françoise


    Assisted reproductive technologies (ART) have changed life for the past 25 years and many ethical and social issues have emerged following this new method of conception. In order to protect individuals against scientific and ethical abuses without inhibiting scientific progress, a specific legal framework is necessary. The first French law on Bioethics was voted after an extensive debate in 1994 then reviewed in 2004. This review previously scheduled every five years is currently being discussed. Legal provisions applying to ART are part of a large framework including the protection of the patients' rights and biomedical research. The key principles consist of respect for human life and ban on commercial practices of human body parts, eugenic practices and any kind of cloning. These key principles apply to ART. Donation is anonymous and free. Created in 2004, the Agence de la biomédecine is a government agency and one of the main tools of the French regulations. The missions focus on improving the quality and the safety of the management of ART. Evaluation of activities is available to all from the annual report. The agency represents the French competent authority for medical and scientific aspects of ART. Substantial differences in European legislations exist from the open-up "laissez faire" to the most restrictive one. As a consequence a large reproductive tourism has developed particularly for egg donation or surrogacy. The medical and ethical conditions of management of patients and donors represent the main critical points. In order to avoid ethical abuses, homogenization regarding the key principles is necessary in Europe. It is an opportunity to reassert that human body parts should not be a source of financial gain.

    Full Text Available Nowadays, many infertile couples can have child by assistant reproductive technology (ART. Always the undesirable effects of these methods on newborn are considered and are evaluated. The aim of this study is to describe the impact of ART on ocular and visual performances of infants born by these methods.In a cross-sectional descriptive study, 479 infants aged three-nine months presented to an optometry clinic of Child Health and Development Research Department (CHDRD, Tehran, Iran. Static retinoscopy, qualitative fixation evaluation, Hirschberg test, red reflex assessment and external eye examination were carried out. Other information such as birth weight and maturity of the infants was recorded.It was possible to assess only 320 out of 479 infants due to general condition of some participants. Comparison of mean refractive error in infants' right and left eyes did not show any significant difference. Our findings confirmed that 20.3% had poor fixation, while 2.9% revealed manifest strabismus. The results also revealed the prevalences of myopia, hyperopia and emmetropia are 2.9%, 87%, and 10.1%, respectively. Red reflex abnormalities were significantly found in boys and in preterm infants (p < 0.05. Failure of fixation control was seen more frequently with increasing refractive error, which significantly developed in preterm infants (p < 0.001.These results reflect the necessity of more comprehensive assessments and further follow-up of infants born by ART, especially for premature male ART infants. These results also suggest the probability of fixation condition and visual deficiencies in these infants. It is recommended to pay close attention to this preliminary report about the refractive and fixation condition of the infants born after ART.

  14. Indicators of perceived useful dementia care assistive technology: Caregivers' perspectives. (United States)

    Mao, Hui-Fen; Chang, Ling-Hui; Yao, Grace; Chen, Wan-Yin; Huang, Wen-Ni Wennie


    The study aims to investigate the caregivers' context-specific perceived usefulness of available assistive technology (AT) devices and the professionals' perspectives on the usefulness indicators of AT devices for home-dwelling individuals with mild-to-moderate dementia. A total of 72 caregivers completed a questionnaire rating 82 AT devices with a high-perceived usefulness (HPU) or low-perceived usefulness (LPU). A total of 21 experts rated 10 usefulness indicators of these devices. We compared the mean of each indicator between the HPU and LPU groups. Most caregivers, who are generally amenable to using AT devices, thought they were useful for helping to care for home-dwelling older adults with mild-to-moderate dementia. The level of perceived usefulness from the experts' perspectives depends on specific design indicators (e.g. familiarity) and the context in which the AT is used (e.g. in everyday life or in emergencies). Indicators for HPU devices were: allows selective accident prevention, has an intuitive interface, is familiar, offers ease of use and simplifies activities. LPU devices featured client prompting. There were no significant differences between HPU and LPU devices with indicators of: is automated, informs caregiver, preserves privacy and preserves autonomy. Safety issues were considered important, and sometimes overshadowed ethical dilemmas, such as privacy and autonomy concern. The present study provides insight into how caregivers perceived the usefulness of AT devices, and how that varied with context. Indicators of devices perceived as useful can serve as guidelines for modifying existing devices and designing new devices. Future application could also incorporate the points of view from the persons with dementia. © 2014 Japan Geriatrics Society.

  15. Tubal factor infertility and perinatal risk after assisted reproductive technology. (United States)

    Kawwass, Jennifer F; Crawford, Sara; Kissin, Dmitry M; Session, Donna R; Boulet, Sheree; Jamieson, Denise J


    To assess trends of tubal factor infertility and to evaluate risk of miscarriage and delivery of preterm or low birth weight (LBW) neonates among women with tubal factor infertility using assisted reproductive technology (ART). We assessed trends of tubal factor infertility among all fresh and frozen, donor, and nondonor ART cycles performed annually in the United States between 2000 and 2010 (N=1,418,774) using the National ART Surveillance System. The data set was then limited to fresh, nondonor in vitro fertilization cycles resulting in pregnancy to compare perinatal outcomes for cycles associated with tubal compared with male factor infertility. We performed bivariate and multivariable analyses controlling for maternal characteristics and calculated adjusted risk ratios (RRs) and 95% confidence intervals (CI). The percentage of ART cycles associated with tubal factor infertility diagnoses decreased from 2000 to 2010 (26.02-14.81%). Compared with male factor infertility, tubal factor portended an increased risk of miscarriage (14.0% compared with 12.7%, adjusted RR 1.08, 95% CI 1.04-1.12); risk was increased for both early and late miscarriage. Singleton neonates born to women with tubal factor infertility had an increased risk of preterm birth (15.8% compared with 11.6%, adjusted RR 1.27, 95% CI 1.20-1.34) and LBW (10.9% compared with 8.5%, adjusted RR 1.28, 95% CI 1.20-1.36). Significant increases in risk persisted for early and late preterm delivery and very low and moderately LBW delivery. A significantly elevated risk was also detected for twin, but not triplet, pregnancies. Tubal factor infertility, which is decreasing in prevalence in the United States, is associated with an increased risk of miscarriage, preterm birth, and LBW delivery as compared with couples with male factor infertility using ART.

    An increasing number of children are born after assisted reproductive technology (ART), and monitoring their long-term health effects is of interest. This study compares cancer risk in children conceived by ART to that in children conceived without. The Medical Birth Registry of Norway contains individual information on all children born in Norway (including information of ART conceptions). All children born between 1984 and 2011 constituted the study cohort, and cancer data were obtained from the Cancer Registry of Norway. Follow-up started at date of birth and ended on the date of the first cancer diagnosis, death, emigration, or December 31, 2011. A Cox proportional hazards model was used to calculate hazard ratios (HR) and 95% confidence intervals (CI) of overall cancer risk between children conceived by ART and those not. Cancer risk was also assessed separately for all childhood cancer types. The study cohort comprised 1 628 658 children, of which 25 782 were conceived by ART. Of the total 4554 cancers, 51 occurred in ART-conceived children. Risk of overall cancer was not significantly elevated (HR 1.21; 95% CI 0.90-1.63). However, increased risk of leukemia was observed for children conceived by ART compared with those who were not (HR 1.67; 95% CI 1.02-2.73). Elevated risk of Hodgkin's lymphoma was also found for ART-conceived children (HR 3.63; 95% CI 1.12-11.72), although this was based on small numbers. This population-based cohort study found elevated risks of leukemia and Hodgkin's lymphoma in children conceived by ART. Copyright © 2016 by the American Academy of Pediatrics.

  17. Older people, assistive technologies, and the barriers to adoption: A systematic review. (United States)

    Yusif, Salifu; Soar, Jeffrey; Hafeez-Baig, Abdul


    Older people generally prefer to continue living in their own homes rather than move into residential age care institutions. Assistive technologies and sensors in the home environment and/or bodily worn systems that monitor people's movement might contribute to an increased sense of safety and security at home. However, their use can raise ethical anxieties as little is known about how older persons perceive assistive and monitoring technologies. To review the main barriers to the adoption of assistive technologies (ATs) by older adults in order to uncover issues of concern from empirical studies and to arrange these issues from the most critical to the least critical. A 4-step systematic review was conducted using empirical studies: locating and identifying relevant articles; screening of located articles; examination of full text articles for inclusion/exclusion; and detail examination of the 44 articles included. Privacy is a top critical concern to older adults, registering a 34% of the total articles examined. Two other equally potent barriers to the adoption of ATs were trust and functionality/added value representing 27 and 25 per cent each respectively of the total studies examined. Also of serious concerns are cost of ATs and ease of use and suitability for daily use (23%) each respectively, perception of "no need" (20%), stigma (18%), and fear of dependence and lack of training (16%) each respectively. These underlying factors are generation/cohort effects and physical decline relating to aging, and negative attitudes toward technologies such as the so-called "gerontechnologies" specifically targeting older adults. However, more and more older adults adopt different kinds of ATs in order to fit in with the society. The identified underlying factors are generation/cohort effects and physical decline relating to aging, and negative attitudes toward technologies. The negative attitudes that are most frequently associated with technologies such as the so

    Jwayyed, Sharhabeel; Stiffler, Kirk A; Wilber, Scott T; Southern, Alison; Weigand, John; Bare, Rudd; Gerson, Lowell W


    Studies on computer-aided instruction and web-based learning have left many questions unanswered about the most effective use of technology-assisted education in graduate medical education. We conducted a review of the current medical literature to report the techniques, methods, frequency and effectiveness of technology-assisted education in graduate medical education. A structured review of MEDLINE articles dealing with "Computer-Assisted Instruction," "Internet or World Wide Web," "Education" and "Medical" limited to articles published between 2002-2007 in the English language was performed. The two literature searches returned 679 articles; 184 met our inclusion and exclusion criteria. In 87 articles, effectiveness was measured primarily using self-reported results from a survey of subjects. Technology-assisted education was superior to traditional methods in 42 of the 64 direct comparison articles (66%, 95% CI 53-77%). Traditional teaching methods were superior to technology-assisted education in only 3/64 (5%, 95% CI 1-13%). The remaining 19 direct comparison articles showed no difference. A detailed review of the 64 comparative studies (technology-assisted education versus traditional teaching methods) also failed to identify a best method or best uses for technology-assisted education. Technology-assisted education is used in graduate medical education across a variety of content areas and participant types. Knowledge gain was the predominant outcome measured. The majority of studies that directly compared knowledge gains in technology-assisted education to traditional teaching methods found technology-assisted education equal or superior to traditional teaching methods, though no "best methods" or "best use" was found within those studies. Only three articles were specific to Emergency Medicine, suggesting further research in our specialty is warranted.

  19. Awareness and barriers to adoption of assistive technologies among visually impaired people in Nigeria. (United States)

    Okonji, Patrick Emeka; Ogwezzy, Darlinton Chukwunalu


    Assistive technology (AT), broadly defined as specialist equipment designed to promote computer access for people with disabilities, is increasingly becoming popular among people with vision impairment as computer use becomes commonplace in society. In developing and emerging economies, however, the adoption of ATs continues to lag behind the developed countries. This study explored barriers to adoption of assistive technologies among visually impaired people in five southern states in Nigeria. A mixed-method approach that employed qualitative interviews with 20 participants and structured questionnaires among 423 participants aged between 20 and 92 was employed. Participants were categorized into two groups: Visually Impaired Adults (VIAs, age range: 20-59 years) and Visually Impaired Older Adults (VIOAs, age range: 60 years and over). The findings show that while 36% of VIA had good awareness of the existence of ACTs, only 17.4% of them had good knowledge of usage. Among VIOA, 20% of them were aware of the existence of ACTs while only 8.07% had a good knowledge of how to use them. Implications of findings for interventions promoting barrier-free digital environment as well as strategies that could foster development of locally specific interventions for digital inclusion are discussed.

  20. Environmental barriers to participation and facilitators for use of three types of assistive technology devices. (United States)

    Widehammar, Cathrine; Lidström, Helene; Hermansson, Liselotte


    The aim was to compare the presence of environmental barriers to participation and facilitators for assistive technology (AT) use and study the relation between barriers and AT use in three different AT devices. A cross-sectional survey was conducted. Inclusion criteria were ≥one year of experience as a user of myoelectric prosthesis (MEP), powered mobility device (PMD), or assistive technology for cognition (ATC) and age 20-90 years. Overall, 156 participants answered the Swedish version of the Craig Hospital Inventory of Environmental Factors and a study-specific questionnaire on facilitating factors. Non-parametric tests were used for comparisons. Barriers to participation were lowest in MEP users (md=0.12; p>0.001), and highest in ATC users (md=1.56; p>0.001) with the least support for AT use (p>0.001 - p=0.048). A positive correlation between fewer barriers and higher use of MEP was seen (r=0.30, p=0.038). The greatest barriers to participation were Natural environment, Surroundings and Information, and the most support came from relatives and professionals. Support, training and education are vital in the use of AT. These factors may lead to a more sustained and prolonged use of AT and may enable increased participation. Future research should focus on interventions that meet the needs of people with cognitive disabilities.

  1. Accuracy of self-reported survey data on assisted reproductive technology treatment parameters and reproductive history. (United States)

    Stern, Judy E; McLain, Alexander C; Buck Louis, Germaine M; Luke, Barbara; Yeung, Edwina H


    It is unknown whether data obtained from maternal self-report for assisted reproductive technology treatment parameters and reproductive history are accurate for use in research studies. We evaluated the accuracy of self-reported in assisted reproductive technology treatment and reproductive history from the Upstate KIDS study in comparison with clinical data reported to the Society for Assisted Reproductive Technology Clinic Outcome Reporting System. Upstate KIDS maternal questionnaire data from deliveries between 2008 and 2010 were linked to data reported to Society for Assisted Reproductive Technology Clinic Outcome Reporting System. The 617 index deliveries were compared as to treatment type (frozen embryo transfer and donor egg or sperm) and use of intracytoplasmic sperm injection and assisted hatching. Use of injectable medications, self-report for assisted reproductive technology, or frozen embryo transfer prior to the index deliveries were also compared. We report agreement in which both sources had yes or both no and sensitivity of maternal report using Society for Assisted Reproductive Technology Clinic Outcome Reporting System as the gold standard. Significance was determined using χ(2) at P self-reported use (P reported than was use of injectable medication (agreement, 76%) (P report in vitro fertilization treatment but are less accurate about procedures handled in the laboratory (intracytoplasmic sperm injection or assisted hatching). Clinics might better communicate with patients on the use of these procedures, and researchers should use caution when using self-reported treatment data. Copyright © 2016 Elsevier Inc.

  4. Moles: Tool-Assisted Environment Isolation with Closures (United States)

    de Halleux, Jonathan; Tillmann, Nikolai

    Isolating test cases from environment dependencies is often desirable, as it increases test reliability and reduces test execution time. However, code that calls non-virtual methods or consumes sealed classes is often impossible to test in isolation. Moles is a new lightweight framework which addresses this problem. For any .NET method, Moles allows test-code to provide alternative implementations, given as .NET delegates, for which C# provides very concise syntax while capturing local variables in a closure object. Using code instrumentation, the Moles framework will redirect calls to provided delegates instead of the original methods. The Moles framework is designed to work together with the dynamic symbolic execution tool Pex to enable automated test generation. In a case study, testing code programmed against the Microsoft SharePoint Foundation API, we achieved full code coverage while running tests in isolation without an actual SharePoint server. The Moles framework integrates with .NET and Visual Studio.

    Khalid, S.; Alam, A.


    Collaborative Virtual Environments (CVEs) falls under Virtual Reality (VR) where two or more users manipulate objects collaboratively. In this paper we have made some experiments to make assembly from constituents parts scattered in Virtual Environment (VE) based on task distribution model using assistance functions for checking and enhancing user performance. The CVEs subjects setting on distinct connected machines via local area network. In this perspective, we consider the effects of assistance function with oral communication on collaboration, co-presence and users performance. Twenty subjects performed collaboratively an assembly task on static and dynamic based task distribution. We examine the degree of influence of assistance function with oral communications on user's performance based on task distribution model. The results show that assistance functions with oral communication based on task distribution model not only increase user performance but also enhance the sense of copresence and awareness.

  6. A Process for Technology Prioritization in a Competitive Environment (United States)

    Stephens, Karen; Herman, Melody; Griffin, Brand


    This slide presentation reviews NASA's process for prioritizing technology requirements where there is a competitive environment. The In-Space Propulsion Technology (ISPT) project is used to exemplify the process. The ISPT project focuses on the mid level Technology Readiness Level (TRL) for development. These are TRL's 4 through 6, (i.e. Technology Development and Technology Demonstration. The objective of the planning activity is to identify the current most likely date each technology is needed and create ISPT technology development schedules based on these dates. There is a minimum of 4 years between flight and pacing mission. The ISPT Project needed to identify the "pacing mission" for each technology in order to provide funding for each area. Graphic representations show the development of the process. A matrix shows which missions are currently receiving pull from the both the Solar System Exploration and the Sun-Solar System Connection Roadmaps. The timeframes of the pacing missions technologies are shown for various types of propulsion. A pacing mission that was in the near future serves to increase the priority for funding. Adaptations were made when budget reductions precluded the total implementation of the plan.

  12. Assisted reproductive technology surveillance--United States, 2009. (United States)

    Sunderam, Saswati; Kissin, Dmitry M; Flowers, Lisa; Anderson, John E; Folger, Suzanne G; Jamieson, Denise J; Barfield, Wanda D


    Since the birth of the first U.S. infant conceived with Assisted Reproductive Technology (ART) in 1981, use of advanced technologies to overcome the problem of infertility has increased steadily, as has the number of fertility clinics providing ART services in the United States. ART includes fertility treatments in which both eggs and sperm are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Women who undergo ART procedures are more likely to deliver multiple-birth infants than those who conceive naturally. Multiple births pose substantial risks to both mothers and infants, including pregnancy complications, preterm delivery, and low birthweight infants. This report presents the most recent data on ART use and birth outcomes for U.S. states and territories. 2009. In 1996, CDC began collecting data on all ART procedures performed in the United States, as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493 [October 24, 1992]). ART data for 1995-2003 were obtained from the Society of Assisted Reproductive Technology (SART) through its proprietary Clinical Outcomes Reporting System data base (SART CORS). Since 2004, CDC has contracted with Westat, Inc., a statistical survey research organization, to obtain data from fertility clinics in the United States through the National ART Surveillance System (NASS), a web-based data collection system developed by CDC. In 2009, a total of 146,244 ART procedures were reported to CDC. These procedures resulted in 45,870 live-birth deliveries and 60,190 infants. The largest numbers of ART procedures were performed among residents of California (18,405), New York (14,539), Illinois (10,192), Massachusetts (9,845), New Jersey (9,146), and Texas (8,244). Together, these six states reported the highest number of live-birth deliveries as a result of ART and accounted for 48% of all ART procedures initiated, 46% of all infants born from ART, and 45

  13. Wireless Control of Smartphones with Tongue Motion Using Tongue Drive Assistive Technology (United States)

    Kim, Jeonghee; Huo, Xueliang


    Tongue Drive System (TDS) is a noninvasive, wireless and wearable assistive technology that helps people with severe disabilities control their environments using their tongue motion. TDS translates specific tongue gestures to commands by detecting a small permanent magnetic tracer on the users’ tongue. We have linked the TDS to a smartphone (iPhone/iPod Touch) with a customized wireless module, added to the iPhone. We also migrated and ran the TDS sensor signal processing algorithm and graphical user interface on the iPhone in real time. The TDS-iPhone interface was evaluated by four able-bodied subjects for dialing 10-digit phone numbers using the standard telephone keypad and three methods of prompting the numbers: visual, auditory, and cognitive. Preliminary results showed that the interface worked quite reliably at a rate of 15.4 digits per minute, on average, with negligible errors. PMID:21096049

  14. Assistive Technologies Promoting the Experience of Self for People with Alzheimer’s Disease

    Directory of Open Access Journals (Sweden)

    Andrea Bosco


    Full Text Available There is growing evidence on the importance of rehabilitation interventions promoting the persistence of the sense of self in people with Alzheimer's disease (AD or other forms of dementia. Assistive Technologies (AT may contribute to the development of interventions aimed to improve adaptive responses to environmental demands. This, in turns, can promote self-awareness. At the same time AT can manage computer interfaces able to record and reproduce autobiographical multimedia contents that can be very useful during reminiscence tasks carried out during conversations with supportive staff. These tasks could promote the self-concept. Globally the AT can be of great help in setting up rehabilitation and leisure environments promoting the experience of self in people with AD and other dementias.

  16. Young people and environment, technology, nuclear energy in France

    International Nuclear Information System (INIS)

    Bernhardt-Crochet, L.


    Young people have a particular attitude on the questions about environment and energy, and also about technology. Several inquiries show that young people are more aware of environmental questions than their elders. Their anxiety is bigger against pollution than the average of French people and it seems that they are more attentive to dangers for the planet: it is the sign of a broader opening on the world. Young people are ready to adhere to a group or association for environment and have sympathy for ecologists; they have hostility against nuclear energy. Age and education level have to be specified to complicate the question. This contribution gives some elements about the opinion of young people between 15-25 years old on environment, technology and nuclear energy in France. (N.C.)

    In the field of assisted reproductive technology (ART), medical accidents can result in serious legal and social consequences. This study was conducted to develop a security system (called IVF-guardian; IG) that could prevent mismatching or mix-ups in ART. A software program was developed in collaboration with outside computer programmers. A quick response (QR) code was used to identify the patients, gametes and embryos in a format that was printed on a label. There was a possibility that embryo development could be affected by volatile organic components (VOC) in the printing material and adhesive material in the label paper. Further, LED light was used as the light source to recognize the QR code. Using mouse embryos, the effects of the label paper and LED light were examined. The stability of IG was assessed when applied in clinical practice after developing the system. A total of 104 cycles formed the study group, and 82 cycles (from patients who did not want to use IG because of safety concerns and lack of confidence in the security system) to which IG was not applied comprised the control group. Many of the label paper samples were toxic to mouse embryo development. We selected a particular label paper (P touch label) that did not affect mouse embryo development. The LED lights were non-toxic to the development of the mouse embryos under any experimental conditions. There were no differences in the clinical pregnancy rates between the IG-applied group and the control group (40/104 = 38.5 % and 30/82 = 36.6 %, respectively). The application of IG in clinical practice did not affect human embryo development or clinical outcomes. The use of IG reduces the misspelling of patient names. Using IG, there was a disadvantage in that each treatment step became more complicated, but the medical staff improved and became sufficiently confident in ART to offset this disadvantage. Patients who received treatment using the IG system also went through a somewhat

  19. Exploring the experience of clients with tetraplegia utilizing assistive technology for computer access. (United States)

    Folan, Alyce; Barclay, Linda; Cooper, Cathy; Robinson, Merren


    Assistive technology for computer access can be used to facilitate people with a spinal cord injury to utilize mainstream computer applications, thereby enabling participation in a variety of meaningful occupations. The aim of this study was to gain an understanding of the experiences of clients with tetraplegia trialing assistive technologies for computer access during different stages in a public rehabilitation service. In order to explore the experiences of clients with tetraplegia trialing assistive technologies for computer use, qualitative methodology was selected. Data were collected from seven participants using semi-structured interviews, which were audio-taped, transcribed and analyzed thematically. Three main themes were identified. These were: getting back into life, assisting in adjusting to injury and learning new skills. The findings from this study demonstrated that people with tetraplegia can be assisted to return to previous life roles or engage in new roles, through developing skills in the use of assistive technology for computer access. Being able to use computers for meaningful activities contributed to the participants gaining an enhanced sense of self-efficacy, and thereby quality of life. Implications for Rehabilitation Findings from this pilot study indicate that people with tetraplegia can be assisted to return to previous life roles, and develop new roles that have meaning to them through the use of assistive technologies for computer use. Being able to use the internet to socialize, and complete daily tasks, contributed to the participants gaining a sense of control over their lives. Early introduction to assistive technology is important to ensure sufficient time for newly injured people to feel comfortable enough with the assistive technology to use the computers productively by the time of discharge. Further research into this important and expanding area is indicated.

  4. Energy technologies and the environment: Environmental information handbook

    Energy Technology Data Exchange (ETDEWEB)


    This revision of Energy Technologies and the Environment reflects the changes in energy supply and demand, focus of environmental concern, and emphasis of energy research and development that have occurred since publication of the earlier edition in 1980. The increase in availability of oil and natural gas, at least for the near term, is responsible in part for a reduced emphasis on development of replacement fuels and technologies. Trends in energy development also have been influenced by an increased reliance on private industry initiatives, and a correspondingly reduced government involvement, in demonstrating more developed technologies. Environmental concerns related to acid rain and waste management continue to increase the demand for development of innovative energy systems. The basic criteria for including a technology in this report are that (1) the technology is a major current or potential future energy supply and (2) significant changes in employing or understanding the technology have occurred since publication of the 1980 edition. Coal is seen to be a continuing major source of energy supply, and thus chapters pertaining to the principal coal technologies have been revised from the 1980 edition (those on coal mining and preparation, conventional coal-fired power plants, fluidized-bed combustion, coal gasification, and coal liquefaction) or added as necessary to include emerging technologies (those on oil shale, combined-cycle power plants, coal-liquid mixtures, and fuel cells).

    The aim of this study was to assess the efficacy of assisted hatching (AH) in assisted reproductive technology (ART) treatment. In this retrospective observational study, the data of patients who were registered in the National ART Registry System of Japan between January and December 2010 were analyzed. The descriptive statistics and validity of AH in fresh embryo transfer (ET) and frozen-thawed ET were assessed by using multiple logistic regression analyses. From a total of 105,450 single ET, 46,029 (43.7%) cycles underwent AH. A total of 9737 (21.3%) and 36,292 (60.9%) cycles underwent AH from 45,818 fresh single ET and 59,632 frozen-thawed single ET, respectively. In the fresh ET patients that underwent AH, the clinical pregnancy and live birth rate were significantly decreased in patients of all ages compared with that of the non-AH group. In the frozen-thawed ET patients, there was no significant difference in pregnancy and live birth rate between the AH group and the non-AH group. AH treatment was more frequently performed in frozen-thawed ET patients than in fresh ET patients, and in the blastocyst stage than in the early cleavage stage. A significantly decreased pregnancy and live birth rate was observed in the fresh ET patients who underwent AH. In the frozen-thawed ET patients who underwent AH, improvement in the clinical pregnancy and live birth rate was not observed. Further studies on the indication and application of AH in ART treatment are required. © 2014 The Authors.

    Méndez-Fernández, Héctor L


    Due to the accelerating rate of the industry's constant innovations, more users become dependent on the most recent technology available on the market. Assistive technology is no exception, as the needs of people with disabilities are constantly changing. A retrospective transversal cohort study was designed in order to evaluate the needs of people with disabilities in relation to assistive technology, and how these needs change over time. This study compares the needs of people with disabilities over the last five years, based on the 952 participants' personal experience in the assistive technology study carried out by Puerto Rico Assistive Technology Program (PRATP) from March 2003 to March 2007. Various statistical tests were carried out in order to determine if there is a significant difference between the reported assistive technology needs and the years of the study. Test results showed a significant statistical association between participants' knowledge level of assistive technology and the years of the study. Similarly, it showed a significant difference between the priority work areas and the years of the study. Besides, statistical associations between sectors, types of disabilities, and work priorities were established in order to determine areas of need in accordance with consumers or service providers' characteristics or particular interests.

    Sánchez-González, Patricia; Burgos, Daniel; Oropesa, Ignacio; Romero, Vicente; Albacete, Antonio; Sánchez-Peralta, Luisa F; Noguera, José F; Sánchez-Margallo, Francisco M; Gómez, Enrique J


    Cognitive skills training for minimally invasive surgery has traditionally relied upon diverse tools, such as seminars or lectures. Web technologies for e-learning have been adopted to provide ubiquitous training and serve as structured repositories for the vast amount of laparoscopic video sources available. However, these technologies fail to offer such features as formative and summative evaluation, guided learning, or collaborative interaction between users. The "TELMA" environment is presented as a new technology-enhanced learning platform that increases the user's experience using a four-pillared architecture: (1) an authoring tool for the creation of didactic contents; (2) a learning content and knowledge management system that incorporates a modular and scalable system to capture, catalogue, search, and retrieve multimedia content; (3) an evaluation module that provides learning feedback to users; and (4) a professional network for collaborative learning between users. Face validation of the environment and the authoring tool are presented. Face validation of TELMA reveals the positive perception of surgeons regarding the implementation of TELMA and their willingness to use it as a cognitive skills training tool. Preliminary validation data also reflect the importance of providing an easy-to-use, functional authoring tool to create didactic content. The TELMA environment is currently installed and used at the Jesús Usón Minimally Invasive Surgery Centre and several other Spanish hospitals. Face validation results ascertain the acceptance and usefulness of this new minimally invasive surgery training environment. Copyright © 2013 Elsevier Inc. All rights reserved.

  11. Birth environment facilitation by midwives assisting in non-hospital births: a qualitative interview study. (United States)

    Igarashi, Toshiko; Wakita, Mariko; Miyazaki, Kikuko; Nakayama, Takeo


    midwifery homes (similar to birth centres) are rich in midwifery wisdom and skills that differ from those in hospital obstetrical departments, and a certain percentage of pregnant women prefer birth in these settings. This study aimed to understand the organisation of the perinatal environment considered important by independent midwives in non-hospital settings and to clarify the processes involved. semi-structured qualitative interview study and constant comparative analysis. 14 independent midwives assisting at births in midwifery homes in Japan, and six independent midwives assisting at home births. Osaka, Kyoto, Nara, and Shiga, Japan. midwives assisting at non-hospital births organised the birth environment based on the following four categories: 'an environment where the mother and family are autonomous'; 'a physical environment that facilitates birth'; 'an environment that facilitates the movement of the mother for birth'; and 'scrupulous safety preparation'. These, along with their sub-categories, are presented in this paper. independent midwives considered it important to create a candid relationship between the midwife and the woman/family from the period of pregnancy to facilitate birth in which the woman and her family were autonomous. They also organised a distinctive environment for non-hospital birth, with preparations to guarantee safety. Experiential knowledge and skills played a major part in creating an environment to facilitate birth, and the effectiveness of this needs to be investigated objectively in future research.

  12. Environment-Assisted Speed-up of the Field Evolution in Cavity Quantum Electrodynamics. (United States)

    Cimmarusti, A D; Yan, Z; Patterson, B D; Corcos, L P; Orozco, L A; Deffner, S


    We measure the quantum speed of the state evolution of the field in a weakly driven optical cavity QED system. To this end, the mode of the electromagnetic field is considered as a quantum system of interest with a preferential coupling to a tunable environment: the atoms. By controlling the environment, i.e., changing the number of atoms coupled to the optical cavity mode, an environment-assisted speed-up is realized: the quantum speed of the state repopulation in the optical cavity increases with the coupling strength between the optical cavity mode and this non-Markovian environment (the number of atoms).

  13. Using assistive technology for schoolwork: the experience of children with physical disabilities. (United States)

    Murchland, Sonya; Parkyn, Helen


    This study explored the experience of children with physical disabilities using assistive technology for participation with schoolwork to gain a greater understanding of their perspectives and subjective experiences. A qualitative study involving thematic analysis of in-depth interviews of the child with a parent or significant adult. Purposeful sampling from a larger study recruited five children aged between 10 and 14 years, with differing physical disabilities who attended mainstream schools. All children used computer-based assistive technology. All of the children recognised that assistive technology enabled them to participate and reduced the impact of their physical disability, allowing independent participation, and facilitated higher learning outcomes. Issues related to ease of use, social implications and assistive technology systems are discussed.

  14. Sound-based assistive technology support to hearing, speaking and seeing

    CERN Document Server

    Ifukube, Tohru


    This book "Sound-based Assistive Technology" explains a technology to help speech-, hearing- and sight-impaired people. They might benefit in some way from an enhancement in their ability to recognize and produce speech or to detect sounds in their surroundings. Additionally, it is considered how sound-based assistive technology might be applied to the areas of speech recognition, speech synthesis, environmental recognition, virtual reality and robots. It is the primary focus of this book to provide an understanding of both the methodology and basic concepts of assistive technology rather than listing the variety of assistive devices developed in Japan or other countries. Although this book presents a number of different topics, they are sufficiently independent from one another that the reader may begin at any chapter without experiencing confusion. It should be acknowledged that much of the research quoted in this book was conducted in the author's laboratories both at Hokkaido University and the University...

    Recently brain-computer interface (BCI) control was integrated into the commercial assistive technology product QualiWORLD (QualiLife Inc., Paradiso-Lugano, CH). Usability of the first prototype was evaluated in terms of effectiveness (accuracy), efficiency (information transfer rate and subjective workload/NASA Task Load Index) and user satisfaction (Quebec User Evaluation of Satisfaction with assistive Technology, QUEST 2.0) by four end-users with severe disabilities. Three assistive technology experts evaluated the device from a third person perspective. The results revealed high performance levels in communication and internet tasks. Users and assistive technology experts were quite satisfied with the device. However, none could imagine using the device in daily life without improvements. Main obstacles were the EEG-cap and low speed.

  19. Applications of electron beam technology for healthcare and environment

    International Nuclear Information System (INIS)

    Varshney, Lalit


    Radiation technology has matured from lab scale to industrial scale in many areas of interests to industry, healthcare, agriculture and environment. Some of the well established applications include radiation sterilization, wires and cable, composites for automobiles, radiation surface curing, nanomaterials, hydrogels and special materials for nuclear and aerospace industry, radiation treatment of effluents, sewage sludge etc. These applications are as a result of characteristics of high energy radiation like gamma and electron beams which are able to deliver energy directly at molecular level. Unlike nuclear based radiations, electron beam accelerator technology is amenable to easy acceptance by public as well has capability to manipulate processes and product treatment to produce varieties of advanced/smart materials for healthcare and environment. Faster dose rates and depth profiling are the important characteristics of electron beam technology which gives it an edge over gamma radiation processing. Department of Atomic Energy has an ambitious program to indigenously develop accelerator technology and utilize them for national progress. In the presentation some important applications of radiation technology will be discussed. (author)

  20. Modelling Technology for Building Fire Scene with Virtual Geographic Environment (United States)

    Song, Y.; Zhao, L.; Wei, M.; Zhang, H.; Liu, W.


    Building fire is a risky activity that can lead to disaster and massive destruction. The management and disposal of building fire has always attracted much interest from researchers. Integrated Virtual Geographic Environment (VGE) is a good choice for building fire safety management and emergency decisions, in which a more real and rich fire process can be computed and obtained dynamically, and the results of fire simulations and analyses can be much more accurate as well. To modelling building fire scene with VGE, the application requirements and modelling objective of building fire scene were analysed in this paper. Then, the four core elements of modelling building fire scene (the building space environment, the fire event, the indoor Fire Extinguishing System (FES) and the indoor crowd) were implemented, and the relationship between the elements was discussed also. Finally, with the theory and framework of VGE, the technology of building fire scene system with VGE was designed within the data environment, the model environment, the expression environment, and the collaborative environment as well. The functions and key techniques in each environment are also analysed, which may provide a reference for further development and other research on VGE.

  2. Risk disparities in the globalisation of assisted reproductive technology: the case of Asia. (United States)

    Ha, Jung-Ok


    This paper analyses the disparities in risks associated with biomedical technology focusing on the results of assisted reproductive technology (ART). ART among biomedical technologies transferred to Asia is a representative case that reveals in its clinical use and related scientific research the global politics of technology. This study notes the global politics at work in the recognition of and reaction to such risks. While many Asian countries aggressively pursue technological development, weak legislative and administrative regulations have created various problems and controversial cases. This study asserts that risks associated with technology are characterised as social facts not natural ones or mere 'side effects', since technological development and risk are closely intertwined.

  6. Assistive technology pricing in Australia: is it efficient and equitable? (United States)

    Summers, Michael P; Verikios, George


    Objective To examine available systematically collected evidence regarding prices for assistive technology (AT; e.g. disability aids and equipment) in Australia with other comparable countries. Issues of appropriate AT pricing are coming to the fore as a consequence of efforts to move to consumer-centric purchasing decisions with the National Disability Insurance Scheme (NDIS) and also in the recent aged care reforms. Methods We identified and present three sets of AT price comparisons. Two comparisons were based solely on the lowest prices advertised on the internet, and one comparison examined recommended retail prices. Variables essential to ensuring accurate comparisons, as well as significant supply-chain issues were also examined and considered in the analyses. Results The first internet-only price comparison found that overall AT prices were 38% higher in Australia compared to other countries, but did not factor in shipping and other related costs that are essential to include given that most AT is imported. The second internet-only price comparison found that overall Australian prices were 24% lower when shipping and related costs were included. The recommended retail price comparisons found that Australian prices were between 14% and 27% lower. Prices for internet-only retailers (those with no bricks-and-mortar presence) are consistently lower for all products than those sold by retailers with actual shop-fronts. Further, there is no evidence of suppliers earning supranormal profits in Australia. Conclusions The results indicate that AT prices in Australia are efficient and equitable, with no significant indicators of market failure which would require government intervention. Efforts to reduce prices through the excessive use of large-scale government procurement programs are likely to reduce diversity and innovation in AT and raise AT prices over time. Open markets and competition with centralised tracking of purchases and providers to minimise possible

  7. Cancer risk among parous women following assisted reproductive technology. (United States)

    Reigstad, M M; Larsen, I K; Myklebust, T Å; Robsahm, T E; Oldereid, N B; Omland, A K; Vangen, S; Brinton, L A; Storeng, R


    Do women who give birth after assisted reproductive technology (ART) have an increased risk of cancer compared with women who give birth without ART? Without correction, the results indicate an increase in overall cancer risk, as well as a 50% increase in risk of CNS cancer for women giving birth after ART, however the results were not significant after correcting for multiple analyses. Studies regarding the effects of hormonal treatments involved with ART on subsequent cancer risk have provided inconsistent results, and it has also been suggested that infertility itself could be a contributory factor. A population-based cohort consisting of all women registered in the Medical Birth Registry of Norway as having given birth between 1 January 1984 and 31 December 2010 was assembled (n = 812 986). Cancers were identified by linkage to the Cancer Registry of Norway. Study subjects were followed from start of first pregnancy during the observational period until the first cancer, death, emigration, or 31 December 2010. Of the total study population (n = 806 248), 16 525 gave birth to a child following ART. Cox regression analysis computed hazard ratios (HR) and 95% confidence intervals (CI) comparing cancer risk between ART women and non-ART women; for overall cancer, and for cervical, ovarian, uterine, central nervous system (CNS), colorectal and thyroid cancers, and for malignant melanoma. A total of 22 282 cohort members were diagnosed with cancer, of which 338 were ART women and 21 944 non-ART women. The results showed an elevated risk in one out of seven sites for ART women. The HR for cancer of the CNS was 1.50 (95% CI 1.03- 2.18), and among those specifically subjected to IVF (without ICSI) the HR was 1.83 (95% CI 1.22-2.73). Analysis of risk of overall cancer gave an HR of 1.16 (95% CI 1.04-1.29). Among those who had delivered only one child by the end of follow-up, the HR for ovarian cancer was 2.00 (95% CI 1.08-3.65), and for those nulliparous at entry the HR

  8. Electricity and the environment: Building partnerships through technology

    Energy Technology Data Exchange (ETDEWEB)

    Yeager, K.E.; Torrens, I. [Electric Power Research Institute, Palo Alto, CA (United States)


    The vision for electricity in the world today transcends its role as just an energy medium and focuses on its ability to furnish ever greater productivity of labor, capital and primary energy resources. Its efficiency and precision, through innovative technology, have become essential assets for resolving the interrelated economic, environmental and energy security issues facing the world. As a result, electricity has become a major differentiating factor in the global economy. For example, the fraction of all primary energy converted to electricity is typically used as a rough indication of regional prosperity. This index reflects the importance of electricity in both creating and harvesting technological innovation. Electricity`s advantages in focusing and amplifying physical power during the first century are being complemented in the second by its even greater advantages for focusing and amplifying the power of knowledge. As its importance grows, electricity will likely expand in the next half-century to provide over half the world`s energy demands while providing the means for the most effective conservation of natural resources. Collaborative R&D organizations such as EPRI are acting as new catalysts and partners to transfer technology on a world-wide basis. With respect to Central and Eastern Europe, this effort focuses on new, more cost-effective innovations for the generation and delivery of electricity because obsolete and inefficient technology is contrary to our mutual interest in achieving efficient and sustainable economic development. EPRI stands ready to assist in this international endeavor.

  9. Patient monitoring in Polish assisted reproductive technology centres

    Directory of Open Access Journals (Sweden)

    Anna Krawczak


    Full Text Available In 2014, the Polish non-governmental patient association ‘Our Stork’ (Nasz Bocian introduced the ‘Patient monitoring in ART centres’ research project to gather previously unrecorded information on the situation of infertile people and the provision of assisted reproductive treatment in Poland. When the research project began, assisted reproductive treatment centres were unregulated by the state, a situation that had existed for more than 28 years following the birth of the first Polish test-tube baby in 1987. Patients signed civil contracts, remaining unprotected in terms of safety of treatment and recognition of their rights, and their presumed social position was described by doctors as ‘disciplined patients’ – a reflection of what Michele Foucault described as biopolitics. The research project comprised patient questionnaires (responses from 722 patients provided the basis for the document ‘Patient Recommendations in Infertility Treatment’, analysis of civil contracts and their accuracy in the context of patients’ legal rights in Poland, and in-depth interviews with assisted reproductive treatment centres’ owners, doctors, midwives, and patients to explore patient care. The data reveal that there is a lack of patient-centred care among doctors and medical staff in Poland and that following the passing into law of the 2015 Infertility Act, which introduced state regulation of assisted reproductive treatment centres, the situation for patients worsened.

  13. The relationship of positive work environments and workplace injury: evidence from the National Nursing Assistant Survey. (United States)

    McCaughey, Deirdre; McGhan, Gwen; Walsh, Erin M; Rathert, Cheryl; Belue, Rhonda


    With estimates of a 51% growth in the number of nursing assistants needed by 2016, there is a critical need to examine workplace factors that negatively contribute to the recruitment and retention of nursing assistants. Studies have shown that high demands, physical stress, and chronic workforce shortages contribute to a working environment that fosters one of the highest workforce injury rates in the United States. The aim of this study was to explore the relationship between nursing assistant injury rates and key outcomes, such as job satisfaction and turnover intent, while exploring workplace environment factors, such as injury prevention training, supervisor support, and employee engagement, that can decrease the rates of workplace injury. Data from the 2004 National Nursing Assistant Survey were used to examine the negative effects of workplace injury on nursing assistants and the workplace environment factors that are related to the rate of worker injury. Nursing assistants who experience job-related injuries have lower levels of job satisfaction, increased turnover intentions, and are less likely to recommend their facility as a place to work or seek care services. It was also found that nursing assistant injury rates are related to employee ratings of injury prevention training, supervisor support, and employee engagement. NAs with multiple injuries (>2) were 1.3-1.6 times more likely to report being injured at work than NAs who had not been injured when supervisor support, employee engagement, and training ratings were low. Evidence that health care organizations can use to better understand how workplace injuries occur and insight into ways to reduce the current staggering rate of on-the-job injuries occurring in health care workplaces were offered in this study. The findings also offer empirical support for an extension of the National Institute for Occupational Health and Safety/National Occupational Research Agenda Work Organization Framework for

    Since the first U.S. infant conceived with Assisted Reproductive Technology (ART) was born in 1981, both the use of advanced technologies to overcome infertility and the number of fertility clinics providing ART services have increased steadily in the United States. ART includes fertility treatments in which both eggs and embryos are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Women who undergo ART procedures are more likely to deliver multiple-birth infants than those who conceive naturally because more than one embryo might be transferred during a procedure. Multiple births pose substantial risks to both mothers and infants, including pregnancy complications, preterm delivery, and low birthweight infants. This report provides state-specific information on U.S. ART procedures performed in 2011 and compares infant outcomes that occurred in 2011 (resulting from procedures performed in 2010 and 2011) with outcomes for all infants born in the United States in 2011. 2011. In 1996, CDC began collecting data on all ART procedures performed in fertility clinics in the United States as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493). Data are collected through the National ART Surveillance System (NASS), a web-based data collecting system developed by CDC. In 2011, a total of 151,923 ART procedures performed in 451 U.S. fertility clinics were reported to CDC. These procedures resulted in 47,818 live-birth deliveries and 61,610 infants. The largest numbers of ART procedures were performed among residents of six states: California (18,808), New York (excluding New York City) (14,576), Massachusetts (10,106), Illinois (9,886), Texas (9,576), and New Jersey (8,698). These six states also had the highest number of live-birth deliveries as a result of ART procedures and together accounted for 47.2% of all ART procedures performed, 45.3% of all infants born from ART, and 45.1% of

  16. Exploring student engagement and transfer in technology mediated environments (United States)

    Sinha, Suparna

    Exploring student engagement and transfer of mechanistic reasoning skills in computer-supported learning environments by SUPARNA SINHA Dissertation Director: Cindy Hmelo-Silver Computer-supported environments designed on learning science principles aim to provide a rich learning experience for students. Students are given opportunities to collaborate, model their understanding, have access to real-time data and engage in hypotheses testing to solve authentic problems. That is to say that affordances of technologies make it possible for students to engage in mechanistic reasoning, a complex inquiry-oriented practice (Machamer, Craver & Darden, 2000; Russ et al., 2008). However, we have limited understanding of the quality of engagement fostered in these contexts. This calls for close observations of the activity systems that the students participate in. The situative perspective focuses on analyzing interactions of individuals (students) with other people, tools and materials within activity systems (Greeno, 2006). Importantly, as the central goal of education is to provide learning experiences that are useful beyond the specific conditions of initial learning, analysis of such interactions sheds light on key experiences that lead to transfer of mechanistic reasoning skills. This is made possible, as computer-supported contexts are activity systems that bring forth trends in students' engagement. From a curriculum design perspective, observing student engagement can be a useful tool to identify features of interactions (with technological tools, peers, curriculum materials) that lead to successful learning. Therefore, the purpose of the present studies is to explore the extent to which technological affordances influence students' engagement and subsequent transfer of reasoning skills. Specifically, the goal of this research is to address the following research questions: How do learners generalize understanding of mechanistic reasoning in computer

  17. Space Suit Environment Testing of the Orion Atmosphere Revitalization Technology (United States)

    Button, Amy B.; Sweterlitsch, Jeffrey J.; Cox, Marlon R.


    An amine-based carbon dioxide (CO2) and water vapor sorbent in pressure-swing regenerable beds has been developed by Hamilton Sundstrand and baselined for the Orion Atmosphere Revitalization System (ARS). In three previous years at this conference, reports were presented on extensive Johnson Space Center (JSC) testing of this technology. That testing was performed in a sea-level pressure environment with both simulated and real human metabolic loads, and in both open and closed-loop configurations. The Orion ARS is designed to also support space-suited operations in a depressurized cabin, so the next step in developmental testing at JSC was to test the ARS technology in a typical closed space suit-loop environment with low-pressure oxygen inside the process loop and vacuum outside the loop. This was the first instance of low-pressure, high-oxygen, closed-loop testing of the Orion ARS technology, and it was conducted with simulated human metabolic loads in March 2009. The test investigated pressure drops and flow balancing through two different styles of prototype suit umbilical connectors. General swing-bed performance was tested with both umbilical configurations, as well as with a short jumper line installed in place of the umbilicals. Other interesting results include observations on the thermal effects of swing-bed operation in a vacuum environment and a recommendation of cycle time to maintain acceptable suit atmospheric CO2 and moisture levels.

  18. Extreme Environment Technologies for Space and Terrestrial Applications (United States)

    Balint, Tibor S.; Cutts, James A.; Kolawa, Elizabeth A.; Peterson, Craig E.


    Over the next decades, NASA's planned solar system exploration missions are targeting planets, moons and small bodies, where spacecraft would be expected to encounter diverse extreme environmental (EE) conditions throughout their mission phases. These EE conditions are often coupled. For instance, near the surface of Venus and in the deep atmospheres of giant planets, probes would experience high temperatures and pressures. In the Jovian system low temperatures are coupled with high radiation. Other environments include thermal cycling, and corrosion. Mission operations could also introduce extreme conditions, due to atmospheric entry heat flux and deceleration. Some of these EE conditions are not unique to space missions; they can be encountered by terrestrial assets from the fields of defense,oil and gas, aerospace, and automotive industries. In this paper we outline the findings of NASA's Extreme Environments Study Team, including discussions on state of the art and emerging capabilities related to environmental protection, tolerance and operations in EEs. We will also highlight cross cutting EE mitigation technologies, for example, between high g-load tolerant impactors for Europa and instrumented projectiles on Earth; high temperature electronics sensors on Jupiter deep probes and sensors inside jet engines; and pressure vessel technologies for Venus probes and sea bottom monitors. We will argue that synergistic development programs between these fields could be highly beneficial and cost effective for the various agencies and industries. Some of these environments, however, are specific to space and thus the related technology developments should be spear headed by NASA with collaboration from industry and academia.

  20. The "Second Place" Problem: Assistive Technology in Sports and (Re) Constructing Normal. (United States)

    Baker, D A


    Objections to the use of assistive technologies (such as prostheses) in elite sports are generally raised when the technology in question is perceived to afford the user a potentially "unfair advantage," when it is perceived as a threat to the purity of the sport, and/or when it is perceived as a precursor to a slippery slope toward undesirable changes in the sport. These objections rely on being able to quantify standards of "normal" within a sport so that changes attributed to the use of assistive technology can be judged as causing a significant deviation from some baseline standard. This holds athletes using assistive technologies accountable to standards that restrict their opportunities to achieve greatness, while athletes who do not use assistive technologies are able to push beyond the boundaries of these standards without moral scrutiny. This paper explores how constructions of fairness and "normality" impact athletes who use assistive technology to compete in a sporting venue traditionally populated with "able-bodied" competitors. It argues that the dynamic and obfuscated construction of "normal" standards in elite sports should move away from using body performance as the measuring stick of "normal," toward alternate forms of constructing norms such as defining, quantifying, and regulating the mechanical actions that constitute the critical components of a sport. Though framed within the context of elite sports, this paper can be interpreted more broadly to consider problems with defining "normal" bodies in a society in which technologies are constantly changing our abilities and expectations of what normal means.

  1. An HL7-FHIR-based Object Model for a Home-Centered Data Warehouse for Ambient Assisted Living Environments. (United States)

    Schwartze, Jonas; Jansen, Lars; Schrom, Harald; Wolf, Klaus-Hendrik; Haux, Reinhold; Marschollek, Michael


    Current AAL environments focus on assisting a single person with seperated technologies. There is no interoperability between sub-domains in home environments, like building energy management or housing industry services. BASIS (Building Automation by a Scalable and Intelligent System) aims to integrate all sensors and actuators into a single, efficient home bus. First step is to create a semtically enriched data warehouse object model. We choose FHIR and built an object model mainly based on the Observation, Device and Location resources with minor extensions needed by AAL-foreign sub domains. FHIR turned out to be very flexible and complete for other home related sub-domains. The object model is implemented in a separated software-partition storing all structural and procedural data of BASIS.

    Full Text Available Human vision and memory are powerful cognitive faculties by which we understand the world. However, they are imperfect and further, subject to deterioration with age. We propose a cognitive-inspired computational model, Extended Visual Memory (EVM, within the Computer-Aided Vision (CAV framework, to assist human in vision-related tasks. We exploit wearable sensors such as cameras, GPS and ambient computing facilities to complement a user's vision and memory functions by answering four types of queries central to visual activities, namely, Retrieval, Understanding, Navigation and Search. Learning of EVM relies on both frequency-based and attention-driven mechanisms to store view-based visual fragments (VF, which are abstracted into high-level visual schemas (VS, both in the visual long-term memory. During inference, the visual short-term memory plays a key role in visual similarity computation between input (or its schematic representation and VF, exemplified from VS when necessary. We present an assisted living scenario, termed EViMAL (Extended Visual Memory for Assisted Living, targeted at mild dementia patients to provide novel functions such as hazard-warning, visual reminder, object look-up and event review. We envisage EVM having the potential benefits in alleviating memory loss, improving recall precision and enhancing memory capacity through external support.

  4. The challenges of caring in a technological environment: critical care nurses' experiences. (United States)

    McGrath, Mary


    This paper presents and discusses the findings from a phenomenological study which illuminated the lived experiences of experienced critical care nurses caring within a technological environment. While nursing practice is interwoven with technology, much of the literature in this area is speculative. Moreover, there is a debate as to whether and how 'high tech' and 'high touch' are reconcilable; this orientation is referred to as the optimism vs. pessimism debate. On a personal level, the motivation for this study came from the author's 13 years' experience in the critical care area. Following ethical approval, 10 experienced nurses from two cardiothoracic critical care units in Ireland participated in the study. A Heideggerian phenomenological methodology was used. Data collection consisted of unstructured interviews. A method of data analysis described by Walters was used. The findings provide research-based evidence to illuminate further the optimistic/pessimistic debate on technology in nursing. While the study demonstrates that the debate is far from resolved, it reveals a new finding: life-saving technology that supports the lives of critically ill patients can bring experienced nurses very close to their patients/families. The three main themes that emerged: 'alien environment', 'pulling together' and 'sharing the journey' were linked by a common thread of caring. Experienced critical care nurses are able to transcend the obtrusive nature of technology to deliver expert caring to their patients. However, the journey to proficiency in technology is very demanding and novice nurses have difficulty in caring with technology. Relevance to clinical practice. It is recommended that more emphasis be placed on supporting, assisting and educating inexperienced nurses in the critical care area and that the use of technology in nursing be given serious consideration.

  6. Assisted Reproductive Technology Surveillance - 
United States, 2013. (United States)

    Sunderam, Saswati; Kissin, Dmitry M; Crawford, Sara B; Folger, Suzanne G; Jamieson, Denise J; Warner, Lee; Barfield, Wanda D


    Since the first U.S. infant conceived with assisted reproductive technology (ART) was born in 1981, both the use of ART and the number of fertility clinics providing ART services have increased steadily in the United States. ART includes fertility treatments in which eggs or embryos are handled in the laboratory (i.e., in vitro fertilization [IVF] and related procedures). Women who undergo ART procedures are more likely than women who conceive naturally to deliver multiple-birth infants. Multiple births pose substantial risks to both mothers and infants, including obstetric complications, preterm delivery, and low birthweight infants. This report provides state-specific information for the United States (including Puerto Rico) on ART procedures performed in 2013 and compares infant outcomes that occurred in 2013 (resulting from ART procedures performed in 2012 and 2013) with outcomes for all infants born in the United States in 2013. 2013. In 1996, CDC began collecting data on ART procedures performed in fertility clinics in the United States as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493). Data are collected through the National ART Surveillance System (NASS), a web-based data collection system developed by CDC. This report includes data from 52 reporting areas (the 50 states, the District of Columbia [DC], and Puerto Rico). In 2013, a total of 160,521 ART procedures (range: 109 in Wyoming to 20,299 in California) with the intent to transfer at least one embryo were performed in 467 U.S. fertility clinics and were reported to CDC. These procedures resulted in 53,252 live-birth deliveries (range: 47 in Alaska to 6,979 in California) and 66,691 infants (range: 61 in Alaska to 8,649 in California). Nationally, the total number of ART procedures performed per million women of reproductive age (15-44 years), a proxy measure of the ART usage rate, was 2,521 (range: 352 in Puerto Rico to 7,688 in DC). ART use

  8. Modeling Sources of Teaching Self-Efficacy for Science, Technology, Engineering, and Mathematics Graduate Teaching Assistants. (United States)

    DeChenne, Sue Ellen; Koziol, Natalie; Needham, Mark; Enochs, Larry


    Graduate teaching assistants (GTAs) in science, technology, engineering, and mathematics (STEM) have a large impact on undergraduate instruction but are often poorly prepared to teach. Teaching self-efficacy, an instructor's belief in his or her ability to teach specific student populations a specific subject, is an important predictor of teaching skill and student achievement. A model of sources of teaching self-efficacy is developed from the GTA literature. This model indicates that teaching experience, departmental teaching climate (including peer and supervisor relationships), and GTA professional development (PD) can act as sources of teaching self-efficacy. The model is pilot tested with 128 GTAs from nine different STEM departments at a midsized research university. Structural equation modeling reveals that K-12 teaching experience, hours and perceived quality of GTA PD, and perception of the departmental facilitating environment are significant factors that explain 32% of the variance in the teaching self-efficacy of STEM GTAs. This model highlights the important contributions of the departmental environment and GTA PD in the development of teaching self-efficacy for STEM GTAs. © 2015 S. E. DeChenne et al.

  12. Stay in the Box! Embedded Assistive Technology Improves Access for Students with Disabilities

    Directory of Open Access Journals (Sweden)

    Katherine Koch


    Full Text Available Assistive technology is not only a required component of a student’s IEP; it can be an effective way to help students with (and without disabilities access their education and to provide them with required instructional accommodations. Teachers, however, are often not adequately prepared in their pre-service course work and ongoing professional development to address the technology needs of their special education students and have not had the opportunities to access technology due to limited availability and cost. While assistive technology can be purchased to augment an existing computer, it is often unnecessary to do that. Both Microsoft and Apple operating systems in “off-the-shelf” computers and handheld devices have embedded assistive technology that is easy to access and easy to use. This embedded technology can help teachers become familiar with technology and assist students with sensory, physical, learning, and attention disabilities, and it might have practical applications with Universal Design for Learning. This paper provides a discussion on how embedded technology can support students with disabilities in the school setting and provides examples for access and use.

  13. Energy storage and the environment: the role of battery technology (United States)

    Ruetschi, Paul

    Batteries can store energy in a clean, convenient and efficient manner. Battery-powered electric vehicles are expected to contribute to a cleaner environment. In today's world, batteries are used everywhere: in electronic watches, pocket calculators, flashlights, toys, radios, tape recorders, cameras, camcorders, laptop computers, cordless telephones, paging devices, hearing aids, heart pacers, instruments, detectors, sensors, memory back-up devices, drug dispensing, wireless tools, toothbrushes, razors, stationary emergency power equipment, automobile starters, electric vehicles, boats, submarines, airplanes and satellites. Worldwide, about 15 billion primary batteries, and well over 200 million starter batteries are produced per year. What is the impact of this widespread use of batteries on the environment? What role can battery technology play in order to reduce undue effects on the environment? Since this paper is presented at a lead/acid battery conference, the discussion refers, in particular, to this system. The following aspects are covered: (i) the three "E" criteria that are applicable to batteries: Energy, Economics, Environment; (ii) service life and environment; (iii) judicious use and service life; (iv) recycling.

  14. Engaging technology-resistant elderly people: Empirical evidence from an ICT-enabled social environment. (United States)

    Papa, Filomena; Cornacchia, Michele; Sapio, Bartolomeo; Nicolò, Enrico


    This paper presents a qualitative investigation on user reactions, opinions, and sentiments about a TV-based technological solution developed within the EasyReach Project of the EU Ambient Assisted Living Joint Program to promote social interaction of less educated elderly people, that is, those individuals who, because of poor scholarization, low income, and, possibly, linguistic barriers, still find it difficult to use computers in order to improve their socialization. Experimental data were collected by extensive trials involving 40 real-end users. A methodology called "scenario engagement" was applied to get participants engaged in a live demonstration with the mediation of a facilitator who assisted elderly people to interact with the system. Results point out that the system can be effectively employed to foster social interaction, particularly when it is introduced in a collective use environment (e.g., Senior Center). Although the focus of the investigation was on information and communication technology-enabled social environments, the end users themselves strongly suggested to include in future system releases extra functions considered as essential opportunities for their potential digital lives: that is, medical or health services and bridges toward public administration.

  15. Assistive technology in occupational therapy practice with a child with degenerative disease of the central nervous system

    Directory of Open Access Journals (Sweden)

    Tácia Caroline de Lima Rodrigues


    Full Text Available This paper aims to report the effects of the interventions, using the resource of assistive technology, carried out with a child with degenerative disease of the central nervous system at his home. This is a study case, which was conducted in seven meetings, addressing the child and his caregivers during a process of evaluation, preparation of assistive devices, family orientation, and evaluation of the family environment repercussion. The results showed that the child presents significant motor, cognitive, and psychosocial impairments, resulting in difficulties in performing activities of daily living, communication, and play. Adjustments were proposed to facilitate the child’s involvement and alleviate family difficulties on equipment and environments, such as wheelchair, bedroom, bathroom, orthosis, toys and communication. Finally, it was possible to note that the assistive technology resources were used according to the child’s needs and his own reality, and that the domiciliary visits contributed positively to the family’s life because they facilitated the child’s care, despite the limitations faced.

  16. Current and future assisted reproductive technologies for fish species. (United States)

    Weber, Gregory M; Lee, Cheng-Sheng


    The Food and Agriculture Organization of the United Nations (FAO) estimates that in 2012 aquaculture production of fish will meet or exceed that of the capture fisheries for the first time. Thus, we have just turned the corner from a predominantly hunting gathering approach to meeting our nutritional needs from fish, to a farming approach. In 2012, 327 finfish species and five hybrids were covered by FAO aquaculture statistics, although farming of carps, tilapias, salmonids, and catfishes account for most of food-fish production from aquaculture. Although for most major species at least part of production is based on what might be considered domesticated animals, only limited production in most species is based on farming of improved lines of fish or is fully independent of wild seedstock. Consistent with the infancy of most aquaculture industries, much of the development and implementation of reproductive technologies over the past 100 years has been directed at completion of the life cycle in captivity in order to increase seed production and begin the process of domestication. The selection of species to farm and the emphasis of selective breeding must also take into account other ways to modify performance of an animal. Reproductive technologies have also been developed and implemented to affect many performance traits among fishes. Examples include technologies to control gender, alter time of sexual maturation, and induce sterilization. These technologies help take advantage of sexually dimorphic growth, overcome problems with growth performance and flesh quality associated with sexual maturation, and genetic containment. Reproductive technologies developed to advance aquaculture and how these technologies have been implemented to advance various sectors of the aquaculture industry are discussed. Finally, we will present some thoughts regarding future directions for reproductive technologies and their applications in finfish aquaculture.

  17. Field Test of Advanced Duct-Sealing Technologies Within the Weatherization Assistance Program

    Energy Technology Data Exchange (ETDEWEB)

    Ternes, MP


    A field test of an aerosol-spray duct-sealing technology and a conventional, best-practice approach was performed in 80 homes to determine the efficacy and programmatic needs of the duct-sealing technologies as applied in the U.S. Department of Energy Weatherization Assistance Program. The field test was performed in five states: Iowa, Virginia, Washington, West Virginia, and Wyoming. The study found that, compared with the best-practice approach, the aerosol-spray technology is 50% more effective at sealing duct leaks and can potentially reduce labor time and costs for duct sealing by 70%, or almost 4 crew-hours. Further study to encourage and promote use of the aerosol-spray technology within the Weatherization Assistance Program is recommended. A pilot test of full production weatherization programs using the aerosol-spray technology is recommended to develop approaches for integrating this technology with other energy conservation measures and minimizing impacts on weatherization agency logistics. In order to allow or improve adoption of the aerosol spray technology within the Weatherization Assistance Program, issues must be addressed concerning equipment costs, use of the technology under franchise arrangements with Aeroseal, Inc. (the holders of an exclusive license to use this technology), software used to control the equipment, safety, and training. Application testing of the aerosol-spray technology in mobile homes is also recommended.

  18. Validating a measure to assess factors that affect assistive technology use by students with disabilities in elementary and secondary education. (United States)

    Zapf, Susan A; Scherer, Marcia J; Baxter, Mary F; H Rintala, Diana


    The purpose of this study was to measure the predictive validity, internal consistency and clinical utility of the Matching Assistive Technology to Child & Augmentative Communication Evaluation Simplified (MATCH-ACES) assessment. Twenty-three assistive technology team evaluators assessed 35 children using the MATCH-ACES assessment. This quasi-experimental study examined the internal consistency, predictive validity and clinical utility of the MATCH-ACES assessment. The MATCH-ACES assessment predisposition scales had good internal consistency across all three scales. A significant relationship was found between (a) high student perseverance and need for assistive technology and (b) high teacher comfort and interest in technology use (p = (0).002). Study results indicate that the MATCH-ACES assessment has good internal consistency and validity. Predisposition characteristics of student and teacher combined can influence the level of assistive technology use; therefore, assistive technology teams should assess predisposition factors of the user when recommending assistive technology. Implications for Rehabilitation Educational and medical professionals should be educated on evidence-based assistive technology assessments. Personal experience and psychosocial factors can influence the outcome use of assistive technology. Assistive technology assessments must include an intervention plan for assistive technology service delivery to measure effective outcome use.

  19. Technological learning in energy-environment-economy modelling: A survey

    International Nuclear Information System (INIS)

    Kahouli-Brahmi, Sondes


    This paper aims at providing an overview and a critical analysis of the technological learning concept and its incorporation in energy-environment-economy models. A special emphasis is put on surveying and discussing, through the so-called learning curve, both studies estimating learning rates in the energy field and studies incorporating endogenous technological learning in bottom-up and top-down models. The survey of learning rate estimations gives special attention to interpreting and explaining the sources of variability of estimated rates, which is shown to be mainly inherent in R and D expenditures, the problem of omitted variable bias, the endogeneity relationship and the role of spillovers. Large-scale models survey show that, despite some methodological and computational complexity related to the non-linearity and the non-convexity associated with the learning curve incorporation, results of the numerous modelling experiments give several new insights with regard to the analysis of the prospects of specific technological options and their cost decrease potential (bottom-up models), and with regard to the analysis of strategic considerations, especially inherent in the innovation and energy diffusion process, in particular the energy sector's endogenous responses to environment policy instruments (top-down models)

  1. Library macro-environment: New technological and economic rules

    Directory of Open Access Journals (Sweden)

    Karmen Štular-Sotošek


    Full Text Available Fast and flexible adaptation to changes in the macro-environment is also crucial for libraries, which have to review them, respond to them and become a part of them. Consequently, the application of marketing science and tools helps libraries to find out how to survive in the competitive world and how to become better and stronger. The article, which draws from marketing, economic and information disciplines, introduces the main principles in the technological and economic environment of libraries and finds the knowledge about these disciplines to be most crucial for successful management of modern libraries, especially on the pretentious publishing market and on the market of information suppliers. Within the technological and economic environment, the cooperation is the only logical solution, which benefits the producers of information services and products as well as libraries. The following text finds that libraries will achieve long-term success and will be proactive in developing partnerships only by using relationship marketing. This relatively new approach offers libraries new ways for successful and long-term management of alliances between partners.

  2. NASA Operational Environment Team (NOET): NASA's key to environmental technology (United States)

    Cook, Beth


    NASA has stepped forward to face the environmental challenge to eliminate the use of Ozone-Layer Depleting Substances (OLDS) and to reduce our Hazardous Air Pollutants (HAP) by 50 percent in 1995. These requirements have been issued by the Clean Air Act, the Montreal Protocol, and various other legislative acts. A proactive group, the NASA Operational Environment Team or NOET, received its charter in April 1992 and was tasked with providing a network through which replacement activities and development experiences can be shared. This is a NASA-wide team which supports the research and development community by sharing information both in person and via a computerized network, assisting in specification and standard revisions, developing cleaner propulsion systems, and exploring environmentally-compliant alternatives to current processes.

  3. Reaction time for processing visual stimulus in a computer-assisted rehabilitation environment. (United States)

    Sanchez, Yerly; Pinzon, David; Zheng, Bin


    To examine the reaction time when human subjects process information presented in the visual channel under both a direct vision and a virtual rehabilitation environment when walking was performed. Visual stimulus included eight math problems displayed on the peripheral vision to seven healthy human subjects in a virtual rehabilitation training (computer-assisted rehabilitation environment (CAREN)) and a direct vision environment. Subjects were required to verbally report the results of these math calculations in a short period of time. Reaction time measured by Tobii Eye tracker and calculation accuracy were recorded and compared between the direct vision and virtual rehabilitation environment. Performance outcomes measured for both groups included reaction time, reading time, answering time and the verbal answer score. A significant difference between the groups was only found for the reaction time (p = .004). Participants had more difficulty recognizing the first equation of the virtual environment. Participants reaction time was faster in the direct vision environment. This reaction time delay should be kept in mind when designing skill training scenarios in virtual environments. This was a pilot project to a series of studies assessing cognition ability of stroke patients who are undertaking a rehabilitation program with a virtual training environment. Implications for rehabilitation Eye tracking is a reliable tool that can be employed in rehabilitation virtual environments. Reaction time changes between direct vision and virtual environment.

  4. Systematic review: investigating the effectiveness of assistive technology to enable internet access for individuals with deafblindness. (United States)

    Perfect, Erin; Jaiswal, Atul; Davies, Theresa Claire


    The purpose of this study is to systematically review published evidence regarding the development, use and effectiveness of assistive devices and technologies that enable internet access for individuals who are deafblind. Eight electronic research databases (CINAHL, Embase, Engineering Village MEDLINE, PsycINFO, PubMed, Cochrane Library, and Web of Science) and three clinical trials registries (ISRCTN Registry, WHO ICTRP, and ClinicalTrials,gov) were searched. Seven articles met the inclusion criteria for this systematic review. The assistive technologies described were in the preliminary stages of development, with only three of the technologies having undergone any testing. The effectiveness of all seven assistive technologies was quantified in this review based on the proposed impacts of internet access on the domains of the World Health Organization's International Classification of Functioning, Disability and Health framework. Internet access technologies for individuals with deafblindness are in the early stages of development and are targeted towards specific functions of the internet. It is imperative that future device development and evaluation seek input from persons who are deafblind. There is also a need to address the gap between academic research which seeks to develop assistive technology to access the internet and the translation into real world use of this technology.

  7. Information and assistance bubbles to help elderly people in public environments. (United States)

    Huertas, Sandra; Lazaro, Juan P; Guillen, Sergio; Traver, Vicente


    Ambient Assisted Living (AAL) is an emerging bundle of technologies and services that has been specially conceived to support disabled and elderly people to be more autonomous in their daily life. Support for mobility is a key aspect in AAL, and makes elderly people feel very independent and socially integrated. This paper describes an AAL solution to support elderly people outside home: provides information and assistance at the street near public buildings, and inside public buildings. The concept of bubble is proposed in this paper as a physical space where it is possible to consume to a number of local services. Presented mobility-based AAL Services are integrated with an ambient assisted home, so users perceive mobility service as an extension of the care chain beyond the boundaries of their homes.

    Gabriela Gonçalves Silveira Fiates


    Full Text Available Innovation has been identified as a strategy to achieve competitive advantage, particularly in contexts of change and especially for technology-based companies – TBCs. Although the adoption of innovation strategies is not easy, small companies have an organizational environment more conducive to innovation. This article examines how managers and employees of small TBCs perceive aspects of the internal environment of innovation in the organization (culture, organizational structure, personnel and infrastructure and their suitability for the innovation process. This is a qualitative research from a multicase study on five companies located in an incubator. Data were collected through open interviews, using a semi-structured script, with one of the managers and two employees from each company. Data were analyzed from preliminary content analysis. The results showed some discrepancies between the perceptions of managers and employees about the issues investigated and their suitability for the innovation system, as well as between reality and the theoretical basis used.

  10. Manipulators in deep ocean environments, needs versus technology

    International Nuclear Information System (INIS)

    Mackey, L.A.; Stenovec, G.M.


    As exploration and production proceed into deeper water, remotely operated vehicles (ROVs) and their manipulators acquire many of the tasks now performed by divers in shallower water. The resulting increased complexity of work tasks requires more dexterious manipulators. Even the most sophisticated of the manipulators today cannot perform many of the work tasks now performed by divers in shallower waters. Manipulators cannot yet duplicate the functions of the human hand. How much technology must be improved to perform the desired tasks, and how much adapting of the work task or equipment must be done to achieve a workable underwater robotics environment?

    Leahy, James A.; Lane, Joseph P.


    Historically, the assistive technology (AT) industry is made up of small to medium size companies serving relatively small markets with products characterized as "niche" or "orphan" products. Presenting opportunities to AT companies that are created by outside sources is difficult. Presenting such opportunities to companies serving larger markets…

  12. Use, non-use and perceived unmet needs of assistive technology among Swedish people in the third age. (United States)

    Löfqvist, Charlotte; Slaug, Björn; Ekström, Henrik; Kylberg, Marianne; Haak, Maria


    To describe the most prominent use of or perceived unmet need of assistive technology (AT) and to compare the characteristics of users, non-users and those expressing perceived unmet need with respect to overall health, independence in everyday life, environmental barriers and socio-demographic features. The study is based on data collected in the "Home and Health in the Third Age Project". In all, 371 individuals participated and data were collected during home visits in southern Sweden by interviewers trained specifically for this project. The data collection comprised well-proven self-report scales and observational formats on the home environment and health indicators as well as questions about basic demographics and socio-structural data. The proportion of users constituted almost half of the total sample. The most common types of AT used were for furnishing/adaptation (35%) and the highest perceived unmet need concerned AT for communication, in total 8%. Those cohabiting were to a higher extent users of AT for furnishing/adaptation, compared to those who lived alone. A higher perceived unmet need was seen among those who lived alone compared with cohabiting people. These findings are of importance for future planning and development of policy to improve health services for the new generation of elderly. Implications for Rehabilitation In order to support the ageing process, the need for assistive technology has to be monitored in the third age. Assistive technology for furnishings and adaptation are frequently used by individuals in their third age and are important to support ageing in the home. Not only do health aspects impact the use of assistive technology, but gender, living conditions and social situation also matter - older men especially need to be monitored thoroughly according to their perceived unmet needs as well as do older persons living alone.

    Trendelkamp-Schroer, Benjamin; Helm, Julius; Strunz, Walter T.


    Open quantum system dynamics of random unitary type may in principle be fully undone. Closely following the scheme of environment-assisted error correction proposed by Gregoratti and Werner [J. Mod. Opt. 50, 915 (2003)], we explicitly carry out all steps needed to invert a phase-damping error on a single qubit. Furthermore, we extend the scheme to a mixed-state environment. Surprisingly, we find cases for which the uncorrected state is closer to the desired state than any of the corrected ones.

  16. The use of assistive technologies after stroke is debunking the myths about the elderly. (United States)

    Tomšič, Marija; Domajnko, Barbara; Zajc, Melita


    Background Through the concept of ageism, we highlight and explain how the society prejudices the elderly. WHO classifies 12 most common stereotypes pertaining to old age. Elderly people are being excluded from social life due to their chronological age rather than any actual reduced physical and/or mental ability. Some of these stereotypes are directly related to the (un)willingness and the ability of the elderly to use technology in everyday life. Objectives The study presented in this article aims to explain the phenomenon of technology use among elderly people who had had a stroke. Method A qualitative study, namely a qualitative content analysis, was performed. Six in-depth interviews with older people who have suffered a stroke were conducted and explored their views on the daily use of technology. Results All older people included in this study used different technologies, which have been divided into technologies that support mobility, technologies for personal care, technologies that support household chores, and technologies for maintaining a social network. An elderly person's attitude toward the use of technology is connected to their social network and assistance from professional staff, as well as the severity of their physical disability. We have found that using various technologies, elderly people are developing various coping strategies. Conclusions After a stroke, a certain degree of physical deterioration can be expected. Nonetheless, our participants managed to compensate for this also with the help of assistive devices and technologies, which negates the myth of simply "surrendering" to the aging process.

  17. Continuing education for Physical Education teachers: Assistive Technology in inclusive education

    Directory of Open Access Journals (Sweden)

    Maria Luiza Salzani Fiorini


    Full Text Available This study aimed at describing the development of continuing education for physical education teachers towards the incorporation of Assistive Technology and the creation of favorable conditions to an inclusive school. The methodology employed was reflective and collaborative research. Two teachers who were facing difficulties to include a physically disabled student and one student with global developmental delay took part in the study. The continuing education plan comprised three steps: 1 reflecting on their own practice after watching a video and planning one lesson, together with the researcher, seeking to incorporate Assistive Technology and favor inclusion; 2 videoing the lesson; 3 evaluating and reflecting on what was planned and what was executed and planning a new lesson. Some factors were seen to be essential to the development of continuing education: considering the teacher’s demand, developing collaborative work, promoting reflection on the practices and having Assistive Technology as a support to the human element.

  18. Assistive technologies along supply chains in health care and in the social services sector. (United States)

    Mayer, Peter; Hauer, Katharina; Schloffer, Evelyn; Leyrer, Barbara


    Health care systems in Austria and Slovenia are currently facing challenges due to scarce resources and demographic change which can be seen especially along the supply chains. The main objective of this paper is to present an option to improve the use of assistive technologies. An extensive literature research for the theoretic part as well as a qualitative survey for the empiric part focusing on short-term care were carried out. Results show that there is a lack of information and training on assistive technologies. As a consequence, their full potential cannot be exploited. Therefore a guideline for nursing consultations was developed. To conclude, both the literature research and the qualitative survey show that assistive technologies have high potentials to improve the supply chains in the health care and social services sector, but there is a lot of information and training on them needed.

  1. Ultrasound assisted chrome tanning: Towards a clean leather production technology. (United States)

    Mengistie, Embialle; Smets, Ilse; Van Gerven, Tom


    Nowadays, there is a growing demand for a cleaner, but still effective alternative for production processes like in the leather industry. Ultrasound (US) assisted processing of leather might be promising in this sense. In the present paper, the use of US in the conventional chrome tanning process has been studied at different pH, temperature, tanning time, chrome dose and US exposure time by exposing the skin before tanning and during tanning operation. Both prior exposure of the skin to US and US during tanning improves the chrome uptake and reduces the shrinkage significantly. Prior exposure of the skin to US increase the chrome uptake by 13.8% or reduces the chrome dose from 8% to 5% (% based on skin weight) and shorten the process time by half while US during tanning increases the chrome uptake by 28.5% or reduces the chrome dose from 8% to 4% (half) and the tanning time to one third compared to the control without US. Concomitantly, the resulting leather quality (measured as skin shrinkage) improved from 5.2% to 3.2% shrinkage in the skin exposed to US prior tanning and to 1.3% in the skin exposed to US during the tanning experiment. This study confirms that US chrome tanning is an effective and eco-friendly tanning process which can produce a better quality leather product in a shorter process time with a lower chromium dose.

    Owuor, John; Larkan, Fiona; Kayabu, Bonnix; Fitzgerald, Geraldine; Sheaf, Greg; Dinsmore, John; McConkey, Roy; Clarke, Mike; MacLachlan, Malcolm


    The aim of this review is to answer the following question: Does assistive technology contribute to social inclusion for people with intellectual disability? Previous research on assistive technology has focused on socioeconomic impacts such as education, employment and access to healthcare by people with intellectual disability. There is a need to consolidate evidence on the interaction between intellectual disability, assistive technology, community living and social inclusion. The review will consider studies from all settings: geographical, socioeconomic and care (institutional and community care), published in English. Studies reported in other languages with abstracts in English will be included if they can be translated using Google Translate, otherwise such studies will be included in the appendix. The review will include both qualitative and quantitative studies. The intervention in this review refers to the use of assistive technology to promote community participation or interpersonal relationships (social inclusion) for people with intellectual disability. The outcomes will be behavioural and social benefits of using assistive technology by people with intellectual disability. Enhanced interpersonal relationships and community participation by people with intellectual disability. Data analysis will be in two phases. The first phase will involve analysis of individual study designs separately. The second phase will be narrative/thematic synthesis of all study groups. The review will not create any ethical or safety concerns. At least one peer-reviewed article in a leading journal such as the BMJ is planned. The findings will also be disseminated through a seminar session involving internal audience at Trinity College Dublin and within the Assistive Technologies for people with Intellectual Disability and Autism research programme.

  4. Enduring politics: the culture of obstacles in legislating for assisted reproduction technologies in Ireland

    Directory of Open Access Journals (Sweden)

    Jill Allison


    Full Text Available Assisted reproductive technology has become a normalized part of reproductive medicine in many countries around the world. Access, however, is uneven and inconsistent, facilitated and restricted by such factors as affordability, social and moral acceptance or refusal and local cultures of medical practice. In Ireland, assisted reproductive technology has been available since 1987 but remains unregulated by legislation. This creates an uncertain and untenable legal circumstance given the contested issues related to constitutional protection of the right to life of the unborn and the indeterminate legal status of embryos in vitro. This paper examines the impact of an enduring political impasse. It explores how clinical assisted reproductive technology services in Ireland operate both inside and outside dominant institutional frameworks, meeting a pronatalist and pro-family social and political agenda, while sometimes contradicting the pro-life politics that has continued to shape women’s reproductive lives. The medical approaches to infertility thus intersect with the ongoing debates around abortion, the failure of the government to regulate, and notions of embodied motherhood and responsibility within changing meanings of family and kinship. At the same time women and their partners seek assisted reproductive technology treatment in other countries throughout the European Union where laws differ and availability of services varies. A decade has passed since the Commission on Assisted Human Reproduction in Ireland released its recommendations; the enduring legislative vacuum leaves women, families and practitioners in potential legal limbo.

  5. Using a Log Analyser to Assist Research into Haptic Technology (United States)

    Jónsson, Fannar Freyr; Hvannberg, Ebba Þóra

    Usability evaluations collect subjective and objective measures. Examples of the latter are time to complete a task. The paper describes use cases of a log analyser for haptic feedback. The log analyser reads a log file and extracts information such as time of each practice and assessment session, analyses whether the user goes off curve and measures the force applied. A study case using the analyser is performed using a PHANToM haptic learning environment application that is used to teach young visually impaired students the subject of polynomials. The paper answers six questions to illustrate further use cases of the log analyser.

  6. Expanding Health Technology Assessments to Include Effects on the Environment. (United States)

    Marsh, Kevin; Ganz, Michael L; Hsu, John; Strandberg-Larsen, Martin; Gonzalez, Raquel Palomino; Lund, Niels


    There is growing awareness of the impact of human activity on the climate and the need to stem this impact. Public health care decision makers from Sweden and the United Kingdom have started examining environmental impacts when assessing new technologies. This article considers the case for incorporating environmental impacts into the health technology assessment (HTA) process and discusses the associated challenges. Two arguments favor incorporating environmental impacts into HTA: 1) environmental changes could directly affect people's health and 2) policy decision makers have broad mandates and objectives extending beyond health care. Two types of challenges hinder this process. First, the nascent evidence base is insufficient to support the accurate comparison of technologies' environmental impacts. Second, cost-utility analysis, which is favored by many HTA agencies, could capture some of the value of environmental impacts, especially those generating health impacts, but might not be suitable for addressing broader concerns. Both cost-benefit and multicriteria decision analyses are potential methods for evaluating health and environmental outcomes, but are less familiar to health care decision makers. Health care is an important and sizable sector of the economy that could warrant closer policy attention to its impact on the environment. Considerable work is needed to track decision makers' demands, augment the environmental evidence base, and develop robust methods for capturing and incorporating environmental data as part of HTA.

  7. Applications of CELSS technology to controlled environment agriculture (United States)

    Bates, Maynard E.; Bubenheim, David L.


    Controlled environment agriculture (CEA) is defined as the use of environmental manipulation for the commercial production of organisms, whether plants or animals. While many of the technologies necessary for aquaculture systems in North America is nevertheless doubling approximately every five years. Economic, cultural, and environmental pressures all favor CEA over field production for many non-commodity agricultural crops. Many countries around the world are already dependent on CEA for much of their fresh food. Controlled ecological life support systems (CELSS), under development at ARC, KSC, and JSC expand the concept of CEA to the extent that all human requirements for food, oxygen, and water will be provided regenerated by processing of waste streams to supply plant inputs. The CELSS will likely contain plants, humans, possibly other animals, microorganisms and physically and chemical processors. In effect, NASA will create engineered ecosystems. In the process of developing the technology for CELSS, NASA will develop information and technology which will be applied to improving the efficiency, reliability, and cost effectiveness for CEA, improving its resources recycling capabilities, and lessening its environmental impact to negligible levels.

  8. Bioremediation: a genuine technology to remediate radionuclides from the environment. (United States)

    Prakash, Dhan; Gabani, Prashant; Chandel, Anuj K; Ronen, Zeev; Singh, Om V


    Radionuclides in the environment are a major human and environmental health concern. Like the Chernobyl disaster of 1986, the Fukushima Daiichi nuclear disaster in 2011 is once again causing damage to the environment: a large quantity of radioactive waste is being generated and dumped into the environment, and if the general population is exposed to it, may cause serious life-threatening disorders. Bioremediation has been viewed as the ecologically responsible alternative to environmentally destructive physical remediation. Microorganisms carry endogenous genetic, biochemical and physiological properties that make them ideal agents for pollutant remediation in soil and groundwater. Attempts have been made to develop native or genetically engineered (GE) microbes for the remediation of environmental contaminants including radionuclides. Microorganism-mediated bioremediation can affect the solubility, bioavailability and mobility of radionuclides. Therefore, we aim to unveil the microbial-mediated mechanisms for biotransformation of radionuclides under various environmental conditions as developing strategies for waste management of radionuclides. A discussion follows of '-omics'-integrated genomics and proteomics technologies, which can be used to trace the genes and proteins of interest in a given microorganism towards a cell-free bioremediation strategy. © 2013 The Authors.

    Gerkowicz, Sabrina A; Crawford, Sara B; Hipp, Heather S; Boulet, Sheree L; Kissin, Dmitry M; Kawwass, Jennifer F


    Information regarding the use of donor sperm in assisted reproductive technology, as well as subsequent treatment and perinatal outcomes, remains limited. Outcome data would aid patient counseling and clinical decision making. The objectives of the study were to report national trends in donor sperm utilization and live birth rates of donor sperm-assisted reproductive technology cycles in the United States and to compare assisted reproductive technology treatment and perinatal outcomes between cycles using donor and nondonor sperm. We hypothesize these outcomes to be comparable between donor and nondonor sperm cycles. This was a retrospective cohort study using data from all US fertility centers reporting to the Centers for Disease Control and Prevention's National Assisted Reproductive Technology Surveillance System, accounting for ∼98% of assisted reproductive technology cycles (definition excludes intrauterine insemination). The number and percentage of assisted reproductive technology cycles using donor sperm and rates of pregnancy, live birth, preterm birth (technology cycles using donor and autologous oocytes performed between 1996 and 2014 (n = 1,710,034). The outcomes analysis was restricted to include only fresh autologous cycles performed between 2010 and 2014 (n = 437,569) to focus on cycles with a potential outcome and cycles reflective of current practice, thereby improving the clinical relevance. Cycles canceled prior to retrieval were excluded. Statistical analysis included linear regression to explore polynomial trends and log-binomial regression to estimate relative risk for outcomes among cycles using donor and nondonor sperm. Of all banking and fresh donor and autologous oocyte assisted reproductive technology cycles performed between 1996 and 2014, 74,892 (4.4%) used donor sperm. In 2014, 7351 assisted reproductive technology cycles using donor sperm were performed, as compared with 1763 in 1996 (6.2% vs 3.8% of all cycles). Among all

    Full Text Available Leisure time is important part of life for each person including visually impaired persons. Education, including studying on higher education studies, is integral and important part of young people's life. In this period of life almost everybody faces with new situations, such as independent decision - making and taking responsibility for these decisions. Making one own's desicions and taking responsibility for them in this part of life seems even demanding when dealing with visual impairment. Assistive technologies contribute to significant changes in our society and play increasing role in everyday life. Use of assistive technologies can provide new opportunities regarding overcoming the barriers, both physical and social, and improving quality of life. A questionnaire consisted of 23 items divided in 3 parts (general information, leisure time activities, aspects of quality of life has been designed for the purpose of this research. The aim of this research was to gain comprehensive insight of assitive technology (players and recorders, electronic magnifier, electronic cane, scener, talking unit, screen readers and screen magnifiers, GPS, cell phones use in leisure time by visually impaired students at University of Zagreb. Participants included in this research were visually imapired students (n=31. The data has been analiyzed with statistical software package Statistica 9, and the results showed the influence of assistive technology use on leisure time activities, as well as the importance and frequency of assitive technology use by visually impaired students. Assistive technologies had the most influence on fulfillment of study obligations quality, creating new contacts and relationships and organizing leisure time. Leisure time activities which are the most affected by using assistive technologies are activities for fun and other interests.

    Ellerby, Don; Gage, Peter; Kazemba, Cole; Mahzari, Milad; Nishioka, Owen; Peterson, Keith; Stackpoole, Mairead; Venkatapathy, Ethiraj; Young, Zion; Poteet, Carl; hide


    The Heat shield for Extreme Entry Environment Technology (HEEET) Project is a NASA STMD and SMD co-funded effort. The goal is to develop and mission infuse a new ablative Thermal Protection System that can withstand extreme entry. It is targeted to support NASAs high priority missions, as defined in the latest decadal survey, to destinations such as Venus and Saturn in-situ robotic science missions. Entry into these planetary atmospheres results in extreme heating. The entry peak heat-flux and associated pressure are estimated to be between one and two orders of magnitude higher than those experienced by Mars Science Laboratory or Lunar return missions. In the recent New Frontiers community announcement NASA has indicated that it is considering providing an increase to the PI managed mission cost (PIMMC) for investigations utilizing the Heat Shield for Extreme Entry Environment Technology (HEEET) and in addition, NASA is considering limiting the risk assessment to only their accommodation on the spacecraft and the mission environment. The HEEET ablative TPS utilizes 3D weaving technology to manufacture a dual layer material architecture. The 3-D weaving allows for flat panels to be woven. The dual layer consists of a top layer designed to withstand the extreme external environment while the inner or insulating layer by design, is designed to achieve low thermal conductivity, and it keeps the heat from conducting towards the structure underneath. Both arc jet testing combined with material properties have been used to develop thermal response models that allows for comparison of performance with heritage carbon phenolic. A 50 mass efficiency is achieved by the dual layer construct compared to carbon phenolic for a broad range of missions both to Saturn and Venus. The 3-D woven flat preforms are molded to achieve the shape as they are compliant and then resin infusion with curing forms a rigid panels. These panels are then bonded on to the aeroshell structure.

In response to increasing interest in robotics technology, the Committee on Gynecologic Practice's Technology Assessment was developed to describe the robotic surgical system,potential advantages and disadvantages, gynecologic applications, and the current state of the evidence. Randomized trials comparing robot-assisted surgery with traditional laparoscopic, vaginal, or abdominal surgery are needed to evaluate long-term clinical outcomes and cost-effectiveness, as well as to identify the best applications of this technology.

  14. Preschool teachers' perception and use of hearing assistive technology in educational settings. (United States)

    Nelson, Lauri H; Poole, Bridget; Muñoz, Karen


    This study explored how often sound-field amplification and personal frequency-modulated (FM) systems are used in preschool classrooms, teacher perceptions of advantages and disadvantages of using hearing assistive technology, and teacher recommendations for hearing assistive technology use. The study used a cross-sectional survey design. Participants were professionals who provided services to preschool-age children who are deaf or hard of hearing in public or private schools. A total of 306 surveys were sent to 162 deaf education programs throughout the United States; 99 surveys were returned (32%). Simple statistics were used to describe the quantitative survey results; content analysis was completed on open-ended survey comments. Surveys were received from teachers working at listening and spoken language preschool programs (65%) and at bilingual-bicultural and total communication preschool programs (35%). Most respondents perceived that hearing assistive technology improved students' academic performance, speech and language development, behavior, and attention in the classroom. The majority of respondents also reported that they definitely would or probably would recommend a sound-field system (77%) or personal FM system (71%) to other educators. Hearing assistive technology is frequently used in preschool classrooms of children who are deaf or hard of hearing, with generally positive teacher perceptions of the benefits of using such technology.

  15. A demographic projection of the contribution of assisted reproductive technologies to world population growth. (United States)

    Faddy, Malcolm J; Gosden, Matthew D; Gosden, Roger G


    Enormous unmet needs for infertility treatment exist because access to assisted reproductive technologies is demographically skewed. Since the first IVF baby in 1978, the number of people conceived by reproductive technology has grown much faster than expected, reaching several million today and rapidly approaching 0.1% of the total world population. As more patients build families, and their children in turn become parents, the number owing their existence to assisted reproductive technologies, either directly or indirectly, will expand tremendously in future decades, but no attempts have been made hitherto to project the magnitude. We have projected growth to the year 2100, along with the fractional contribution to world population. The chief variable driving growth is access to fertility services. If it stagnates at current levels of about 400,000 babies per year, an estimated 157 million people alive at the end of the century will owe their lives to assisted reproductive technologies (1.4% of global population), but at an arbitrary upper limit of 30,000 extra births annually there will be 394 million additional people alive (3.5%). As the conquest of infertility continues, individuals who owe their lives to assisted reproductive technologies will quietly make a significant contribution to demographic growth as well as social progress.

  16. Innovative assistive technology in Finnish public elderly-care services: a focus on productivity. (United States)

    Melkas, Helinä


    The study investigates ways in which technology use may help municipalities improve productivity in elderly-care services. A case study of Finnish elderly-care services provides responses concerning impacts, decisions and options in technology use. The research data were collected during a 'smart home pilot' implemented in four housing service units. Over 60 assistive devices were introduced in the smart homes used during short-term housing periods. Both customers and care staff's experiences as well as processes related to the use of assistive devices were investigated on the basis of survey questionnaires, interviews and feedback. Assistive device-related operational processes were investigated with the help of concepts of 'resource focus', 'lost motion' and 'intermediate storage'. Four central operational processes were identified. Design and desirability as well as costs, such as opportunity costs of assistive devices were also a focus. Significant factors related to productivity were disclosed in this way. Technology use versus productivity needs to be 'circled' from the points of view of individual users, workplaces, service processes, and larger technology options. There must be long-term patience to introduce technology properly into use to produce positive impacts on productivity. Customers and care staff have an interlinked, vital role to play as decision-makers' informants.

  18. Assistive technologies for pain management in people with amputation: a literature review. (United States)

    Ghoseiri, Kamiar; Allami, Mostafa; Soroush, Mohammad Reza; Rastkhadiv, Mohammad Yusuf


    The prevalence of limb amputation is increasing globally as a devastating experience that can physically and psychologically affect the lifestyle of a person. The residual limb pain and phantom limb pain are common disabling sequelae after amputation surgery. Assistive devices/technologies can be used to relieve pain in people with amputation. The existing assistive devices/technologies for pain management in people with amputation include electrical nerve block devices/technologies, TENS units, elastomeric pumps and catheters, residual limb covers, laser systems, myoelectric prostheses and virtual reality systems, etc. There is a great potential to design, fabricate, and manufacture some portable, wireless, smart, and thin devices/technologies to stimulate the spinal cord or peripheral nerves by electrical, thermal, mechanical, and pharmaceutical stimulus. Although some preliminary efforts have been done, more attention must be paid by researchers, clinicians, designers, engineers, and manufacturers to the post amputation pain and its treatment methods.

  19. Intelligent navigation and accurate positioning of an assist robot in indoor environments (United States)

    Hua, Bin; Rama, Endri; Capi, Genci; Jindai, Mitsuru; Tsuri, Yosuke


    Intact robot's navigation and accurate positioning in indoor environments are still challenging tasks. Especially in robot applications, assisting disabled and/or elderly people in museums/art gallery environments. In this paper, we present a human-like navigation method, where the neural networks control the wheelchair robot to reach the goal location safely, by imitating the supervisor's motions, and positioning in the intended location. In a museum similar environment, the mobile robot starts navigation from various positions, and uses a low-cost camera to track the target picture, and a laser range finder to make a safe navigation. Results show that the neural controller with the Conjugate Gradient Backpropagation training algorithm gives a robust response to guide the mobile robot accurately to the goal position.

  1. Remote Mine Detection Technologies for Land and Water Environments

    Energy Technology Data Exchange (ETDEWEB)

    Hoover, Eddie R.


    The detection of mines, both during and after hostilities, is a growing international problem. It limits military operations during wartime and unrecovered mines create tragic consequences for civilians. From a purely humanitarian standpoint an estimated 100 million or more unrecovered mines are located in over 60 countries worldwide. This paper presents an overview of some of the technologies currently being investigated by Sandia National Laboratories for the detection and monitoring of minefields in land and water environments. The three technical areas described in this paper are: 1) the development of new mathematical techniques for combining or fusing the data from multiple sources for enhanced decision-making; 2) an environmental fate and transport (EF&T) analysis approach that is central to improving trace chemical sensing technique; and 3) the investigation of an underwater range imaging device to aid in locating and characterizing mines and other obstacles in coastal waters.

    Maignien, Chloé; Santulli, Pietro; Gayet, Vanessa; Lafay-Pillet, Marie-Christine; Korb, Diane; Bourdon, Mathilde; Marcellin, Louis; de Ziegler, Dominique; Chapron, Charles


    Assisted reproductive technology is one of the therapeutic options offered for managing endometriosis-associated infertility. Yet, published data on assisted reproductive technology outcome in women affected by endometriosis are conflicting and the determinant factors for pregnancy chances unclear. We sought to evaluate assisted reproductive technology outcomes in a series of 359 endometriosis patients, to identify prognostic factors and determine if there is an impact of the endometriosis phenotype. This was a retrospective observational cohort study, including 359 consecutive endometriosis patients undergoing in vitro fertilization or intracytoplasmic sperm injection, from June 2005 through February 2013 at a university hospital. Endometriotic lesions were classified into 3 phenotypes-superficial peritoneal endometriosis, endometrioma, or deep infiltrating endometriosis-based on imaging criteria (transvaginal ultrasound, magnetic resonance imaging); histological proof confirmed the diagnosis in women with a history of surgery for endometriosis. Main outcome measures were clinical pregnancy rates and live birth rates per cycle and per embryo transfer. Prognostic factors of assisted reproductive technology outcome were identified by comparing women who became pregnant and those who did not, using univariate and adjusted multiple logistic regression models. In all, 359 endometriosis patients underwent 720 assisted reproductive technology cycles. In all, 158 (44%) patients became pregnant, and 114 (31.8%) had a live birth. The clinical pregnancy rate and the live birth rate per embryo transfer were 36.4% and 22.8%, respectively. The endometriosis phenotype (superficial endometriosis, endometrioma, or deep infiltrating endometriosis) had no impact on assisted reproductive technology outcomes. After multivariate analysis, history of surgery for endometriosis (odds ratio, 0.14; 95% confidence ratio, 0.06-0.38) or past surgery for endometrioma (odds ratio, 0.39; 95

  7. The clinical benefit and safety of current and future assisted reproductive technology. (United States)

    Brown, Rachel; Harper, Joyce


    Since the first birth by IVF was achieved in 1978, the techniques involved in assisted reproductive technology have grown at an enormous rate. However, new technology has rarely been robustly validated before clinical use and developing scientific understanding of the available techniques has done little to alter their use. Furthermore, there are inconsistencies in the available clinical studies and endpoints. The benefits of some technologies already established for routine use are currently dubious and there are clear ethical concerns with providing them to patients when their scientific basis is not clear. As the uptake of assisted reproductive technology increases and newer technologies continue to push the boundaries of science, it is important to consider the clinical benefits and safety of all assisted reproductive technologies. This review will discuss aspects of some of the more recent techniques, including sperm DNA-damage tests, intracytoplasmic morphologically selected sperm injection, amino acid and metabolomics profiling, preimplantation genetic screening and time-lapse imaging, and those that may have substantial impacts on the field of reproductive medicine in the future including artificial gametes, ovarian transplantation and gene therapy.

    The aim of this study was to describe the current regulatory environment in Greece to evaluate the potential introduction of health technology assessment (HTA) for medicinal products for human use. Data sources consist of national legislation on pricing and reimbursement of health technologies to identify the potential need of establishing HTA and its relevant structure. The pricing procedure regarding medicinal products for human use is based on an external reference pricing mechanism which considers the average of the three lowest Euorpean Union prices. Currently, a formal HTA procedure has not been applied in Greece, and the only prerequisite used for the reimbursement of medicinal products for human use is their inclusion in the Positive Reimbursement List. To restrict pharmaceutical expenditure, a variety of measures-such as clawback mechanisms, rebates, monthly budget caps per physician, generics penetration targeting-have been imposed, aiming mainly to regulate the price level rather than control the introduction of medicinal products for human use in the Greek pharmaceutical market. Greece has the opportunity to rapidly build capacity, implement, and take advantage of the application of HTA mechanisms by clearly defining the goals, scope, systems, context, stakeholders, and methods that will be involved in the local HTA processes, taking into account the country's established e-prescription system and the recently adapted legislative framework.

  9. The Technology Information Environment with Industry{trademark} system description

    Energy Technology Data Exchange (ETDEWEB)

    Detry, R.; Machin, G. [Sandia National Labs., Albuquerque, NM (United States). Scientific Computing Systems Dept.


    The Technology Information Environment with Industry (TIE-In{trademark}) provides users with controlled access to distributed laboratory resources that are packaged in intelligent user interfaces. These interfaces help users access resources without requiring the user to have technical or computer expertise. TIE-In utilizes existing, proven technologies such as the Kerberos authentication system, X-Windows, and UNIX sockets. A Front End System (FES) authenticates users and allows them to register for resources and subsequently access them. The FES also stores status and accounting information, and provides an automated method for the resource owners to recover costs from users. The resources available through TIE-In are typically laboratory-developed applications that are used to help design, analyze, and test components in the nation`s nuclear stockpile. Many of these applications can also be used by US companies for non-weapons-related work. TIE-In allows these industry partners to obtain laboratory-developed technical solutions without requiring them to duplicate the technical resources (people, hardware, and software) at Sandia.

  10. Invisible transportation infrastructure technology to mitigate energy and environment. (United States)

    Hossain, Md Faruque


    Traditional transportation infrastructure built by heat trapping products and the transportation vehiles run by fossil fuel, both causing deadly climate change. Thus, a new technology of invisible Flying Transportation system has been proposed to mitigate energy and environmental crisis caused by traditional infrastructure system. Underground Maglev system has been modeled to be constructed for all transportation systems to run the vehicle smoothly just over two feet over the earth surface by propulsive and impulsive force at flying stage. A wind energy modeling has also been added to meet the vehicle's energy demand when it runs on a non-maglev area. Naturally, all maglev infrastructures network to be covered by evergreen herb except pedestrian walkways to absorb CO 2 , ambient heat, and moisture (vapor) from the surrounding environment to make it cool. The research revealed that the vehicle will not require any energy since it will run by superconducting electromagnetic force while it runs on a maglev infrastructure area and directed by wind energy while it runs on non-maglev area. The proposed maglev transportation infrastructure technology will indeed be an innovative discovery in modern engineering science which will reduce fossil fuel energy consumption and climate change dramatically.

  12. High-Temperature Adhesives for Thermally Stable Aero-Assist Technologies (United States)

    Eberts, Kenneth; Ou, Runqing


    Aero-assist technologies are used to control the velocity of exploration vehicles (EVs) when entering Earth or other planetary atmospheres. Since entry of EVs in planetary atmospheres results in significant heating, thermally stable aero-assist technologies are required to avoid the high heating rates while maintaining low mass. Polymer adhesives are used in aero-assist structures because of the need for high flexibility and good bonding between layers of polymer films or fabrics. However, current polymer adhesives cannot withstand temperatures above 400 C. This innovation utilizes nanotechnology capabilities to address this need, leading to the development of high-temperature adhesives that exhibit high thermal conductivity in addition to increased thermal decomposition temperature. Enhanced thermal conductivity will help to dissipate heat quickly and effectively to avoid temperature rising to harmful levels. This, together with increased thermal decomposition temperature, will enable the adhesives to sustain transient high-temperature conditions.

  13. Ethics of emergent information and communication technology applications in humanitarian medical assistance. (United States)

    Hunt, Matthew; Pringle, John; Christen, Markus; Eckenwiler, Lisa; Schwartz, Lisa; Davé, Anushree


    New applications of information and communication technology (ICT) are shaping the way we understand and provide humanitarian medical assistance in situations of disaster, disease outbreak or conflict. Each new crisis appears to be accompanied by advancements in humanitarian technology, leading to significant improvements in the humanitarian aid sector. However, ICTs raise ethical questions that warrant attention. Focusing on the context of humanitarian medical assistance, we review key domains of ICT innovation. We then discuss ethical challenges and uncertainties associated with the development and application of new ICTs in humanitarian medical assistance, including avoiding harm, ensuring privacy and security, responding to inequalities, demonstrating respect, protecting relationships, and addressing expectations. In doing so, we emphasize the centrality of ethics in humanitarian ICT design, application and evaluation. © The Author 2016.

  16. The Assimilation of Assistive Technology in Residential Care Centers for People with Intellectual Disabilities

    Directory of Open Access Journals (Sweden)

    Eli Carmeli


    Full Text Available People with intellectual disability (ID require special support in order to achieve independence in their daily life. Persons with ID are less exposed to assistive technology, although studies have shown that the availability of aids afford an opportunity to reach independence and cooperation. The aim of this study was to examine the nature of the relationship between involvement of the physiotherapy (PT team and the degree to which assistive technology was used. A questionnaire was sent to all PTs employed at all 54 residential care centers for persons with ID of the Division for Mental Retardation at the Ministry of Social Affairs in Israel. A significantly positive correlation was found between the degree of involvement of the PT and the utilization of assistive technology. The study results may be summarized by stating that PTs demonstrated a great deal of involvement, particularly in relation to the extent of their work in the residential care centers. PT's awareness of the importance was indicated as the major reason to use assistive technology.

    Nyfløt, L T; Sandven, I; Oldereid, N B; Stray-Pedersen, B; Vangen, S


    To investigate the association between assisted reproductive technology and severe postpartum haemorrhage. Case-control study. The study was conducted in Norway; Division of Gynaecology and Obstetrics at Oslo University Hospital and Department of Obstetrics and Gynaecology at Drammen Hospital. A source population including all women admitted for delivery at Oslo University Hospital and Drammen Hospital during the time period 1 January 2008 to 31 December 2011. The study population consisted of all cases of severe postpartum haemorrhage (n = 1064) and a random sample of controls (n = 2059). We used an explanatory strategy in the analysis, with multivariable logistic regression. Severe postpartum haemorrhage; defined as blood loss ≥1500 ml or need for blood transfusion. Assisted reproductive technology was associated with an increased risk of severe postpartum haemorrhage (crude OR = 2.92; 95% CI 2.18-3.92, P single gestation (adjusted OR = 1.58, 95% CI 1.12-2.24, P = 0.010). Our findings warrant an increased awareness of the risk of severe postpartum haemorrhage in women conceiving with assisted reproductive technology. Furthermore, the high risk of severe postpartum haemorrhage in the presence of a twin or triplet pregnancy is an additional argument for single embryo transfer. Assisted reproductive technology is associated with an increased risk of severe postpartum haemorrhage. © 2016 Royal College of Obstetricians and Gynaecologists.

  5. CDC-reported assisted reproductive technology live-birth rates may mislead the public. (United States)

    Kushnir, Vitaly A; Choi, Jennifer; Darmon, Sarah K; Albertini, David F; Barad, David H; Gleicher, Norbert


    The Centre for Disease Control and Prevention (CDC) publicly reports assisted reproductive technology live-birth rates (LBR) for each US fertility clinic under legal mandate. The 2014 CDC report excluded 35,406 of 184,527 (19.2%) autologous assisted reproductive technology cycles that involved embryo or oocyte banking from LBR calculations. This study calculated 2014 total clinic LBR for all patients utilizing autologous oocytes two ways: including all initiated assisted reproductive technology cycles or excluding banking cycles, as done by the CDC. The main limitation of this analysis is the CDC report did not differentiate between cycles involving long-term banking of embryos or oocytes for fertility preservation from cycles involving short-term embryo banking. Twenty-seven of 458 (6%) clinics reported over 40% of autologous cycles involved banking, collectively performing 12% of all US assisted reproductive technology cycles. LBR in these outlier clinics calculated by the CDC method, was higher than the other 94% of clinics (33.1% versus 31.1%). However, recalculated LBR including banking cycles in the outlier clinics was lower than the other 94% of clinics (15.5% versus 26.6%). LBR calculated by the two methods increasingly diverged based on proportion of banking cycles performed by each clinic reaching 4.5-fold, thereby, potentially misleading the public.

  13. The experience of pregnancy resulting from Assisted Reproductive Technology (ART) treatment: A qualitative Brazilian study. (United States)

    Dornelles, L M N; MacCallum, F; Lopes, R C S; Piccinini, C A; Passos, E P


    Pregnancies achieved through medical treatments following a period of infertility may demand extra emotional and practical investment from women. This paper aims at understanding the experience of pregnancy after Assisted Reproductive Technology, and exploring whether this experience is affected by previous failed infertility treatments. This paper uses a qualitative approach. Participants were nineteen expectant first-time mothers from Brazil who conceived through Assisted Reproductive Technology treatment. During the third trimester of gestation, a semi-structured interview was administered to assess perceptions of and feelings about treatment and pregnancy. Interview transcripts were analysed using thematic analysis, and the sample was divided into two groups according to whether it was the participant's first treatment or not. Themes identified include: tolerance of the demands of treatment and pregnancy, consideration of the mechanics of treatment and pregnancy, and emotionally painful aspects of treatment and pregnancy. Pregnancy itself was regarded as a reward or compensation for the difficulties undergone. Perspectives differed according to whether pregnancy followed the first Assisted Reproductive Technology treatment; those who had undergone previously unsuccessful treatments focused less on the mechanical aspects of the process but were more concerned about possible physical problems. The similarities and differences found according to number of treatments attempted should be taken into consideration when providing psychological support for expectant Assisted Reproductive Technology mothers.

    Elsaesser, Linda-Jeanne; Bauer, Stephen M


    PURPOSE. This article develops a standardised method for assistive technology service (ATS) provision and a logical basis for research to improve health care quality. The method is 'interoperable' across disabilities, disciplines, assistive technology devices and ATSs. BACKGROUND. Absence of a standardised and interoperable method for ATS provision results in ineffective communication between providers, manufacturers, researchers, policy-makers and individuals with disabilities (IWD), a fragmented service delivery system, inefficient resource allocation and sub-optimal outcomes. OBJECTIVES. Synthesise a standardised, interoperable AT service method (ATSM) fully consistent with key guidelines, systems, models and Federal legislation. Express the ATSM using common and unambiguous language. RESULTS. Guidelines, systems, models and Federal legislation relevant to ATS provision are reviewed. These include the RESNA Guidelines for Knowledge and Skills for Provision of Assistive Technology Products and Services (RESNA Guidelines), IMPACT2 model, international classification of functioning, disability and health (ICF) and AT device classification (ATDC). Federal legislation includes the Assistive Technology Act of 2004, Americans with Disabilities Act of 2008 and Social Security Act. Based on these findings, the ATSM is synthesised and translated into common and accessible language. CONCLUSION. ATSM usage will improve communication between stakeholders, service delivery coherence, resource allocation and intervention outcomes.

Data were obtained from 123 adults with hearing impairment: 73 reported current hearing-aid use, 81 reported current hearing assistance technology use. In both analyses, device users had more difficulty understanding speech in background noise, had poor hearing in both their better and worse hearing ears, and perceived more consequences of hearing impairment in their everyday lives (both emotionally and socially) than non-hearing-aid users. Discriminant analyses showed that the social consequences of hearing impairment and the better ear hearing best classified hearing aid users from non-users but social consequences and worse ear hearing best classified hearing assistance technology users from non-users. Quality of life measurements and speech-in-noise assessments provide useful clinical information. Hearing-impaired adults in New Zealand who use hearing aids also tend to use hearing assistance technology, which has important clinical implications.

    Borg, Johan; Larsson, Stig; Ostergren, Per-Olof


    Despite its facilitating role in creating opportunities for people with disabilities to exercise human rights, access to assistive technology is limited in many countries. It is therefore promising that the Convention on Rights of Persons with Disabilities (CRPD) addresses this area. The purpose of this study was to analyse the assistive…

  9. Assistance system for nuclear data evaluation in an object-oriented environment

    International Nuclear Information System (INIS)

    Iwasaki, S.; Odano, N.; Sugiyama, K.


    An object-oriented framework for an assistance system for neutron nuclear data evaluation has been proposed, and an assisting system for theoretical model fitting to the experimental data has been developed. In the model fitting procedure, we employed a method based on the general least-squares technique. Almost all things appearing in the process were easily and naturally modeled by objects in this environment. The objects can also be connected by a set of rules either with other objects, with the existing or newly developed external processes and with data bases. In total twelve sub-processes were supported by each knowledge base. As an example of the fitting procedure the case of 59 Co as the target nuclide is presented. (Author)

  10. Gonadotrophin-releasing hormone antagonists for assisted reproductive technology. (United States)

    Al-Inany, Hesham G; Youssef, Mohamed A; Ayeleke, Reuben Olugbenga; Brown, Julie; Lam, Wai Sun; Broekmans, Frank J


    Gonadotrophin-releasing hormone (GnRH) antagonists can be used to prevent a luteinizing hormone (LH) surge during controlled ovarian hyperstimulation (COH) without the hypo-oestrogenic side-effects, flare-up, or long down-regulation period associated with agonists. The antagonists directly and rapidly inhibit gonadotrophin release within several hours through competitive binding to pituitary GnRH receptors. This property allows their use at any time during the follicular phase. Several different regimens have been described including multiple-dose fixed (0.25 mg daily from day six to seven of stimulation), multiple-dose flexible (0.25 mg daily when leading follicle is 14 to 15 mm), and single-dose (single administration of 3 mg on day 7 to 8 of stimulation) protocols, with or without the addition of an oral contraceptive pill. Further, women receiving antagonists have been shown to have a lower incidence of ovarian hyperstimulation syndrome (OHSS). Assuming comparable clinical outcomes for the antagonist and agonist protocols, these benefits would justify a change from the standard long agonist protocol to antagonist regimens. This is an update of a Cochrane review first published in 2001, and previously updated in 2006 and 2011. To evaluate the effectiveness and safety of gonadotrophin-releasing hormone (GnRH) antagonists compared with the standard long protocol of GnRH agonists for controlled ovarian hyperstimulation in assisted conception cycles. We searched the Cochrane Menstrual Disorders and Subfertility Group Trials Register (searched from inception to May 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, inception to 28 April 2015), Ovid MEDLINE (1966 to 28 April 2015), EMBASE (1980 to 28 April 2015), PsycINFO (1806 to 28 April 2015), CINAHL (to 28 April 2015) and trial registers to 28 April 2015, and handsearched bibliographies of relevant publications and reviews, and abstracts of major scientific meetings, for

  11. [Horus: technological innovation in pharmaceutical assistance within the Brazilian unified health system]. (United States)

    Costa, Karen Sarmento; Nascimento, José Miguel do


    To analyze results of the Horus Information System, comparing elements of this system with some international experiences. Horus is a technological innovation introduced in 2009 in the Pharmaceutical management information system of the Sistema Único de Saúde (Brazilian Unified Health System). In 2011, local managers and health professionals of 1,247 municipalities (16 states) that adhered to Horus answered questionnaires on pharmaceutical assistance in primary care and about the Horus system. This is a descriptive and exploratory study, developed with the use of quantitative and qualitative methods of research. Multivariate tools were used for data collection and interpretative support of the statistical inference and thematic analysis. The main changes identified after the implementation of this system were: improvement on technical and scientific quality control of Pharmaceutical Assistance, improvement on the supply of medications and health care; training of human resources and knowledge management; improvement on the relationship health managers/users; development in the administrative management and greater inter-state management; and improvement on the technological infrastructure. In terms of health information systems, these categories are consistent with programs and obstacles observed in international experiences. The biggest gap identified was the fact that Horus was not included in a national policy of health information systems, which is in a process of consolidation in Brazil. The national database of actions and services within the Pharmaceutical Assistance will enable the collection, analysis and dissemination of information regarding integrated pharmaceutical assistance in the Brazilian context. The Horus System is a technological innovation that enables the management of the Pharmaceutical Assistance. The national base will enable the definition and agreement on national indicators of Pharmaceutical Assistance, aiming to produce evidence of

  14. Trends and correlates of good perinatal outcomes in assisted reproductive technology. (United States)

    Joshi, Nikhil; Kissin, Dmitry; Anderson, John E; Session, Donna; Macaluso, Maurizio; Jamieson, Denise J


    To estimate trends in good perinatal outcomes (singleton live births at term with birthweight more than 2,500 g) among live births after assisted reproductive technology in the United States from 2000 to 2008, and associated factors among singletons in 2008. Using retrospective cohort data from the National Assisted Reproductive Technology Surveillance System from 2000 to 2008, we calculated relative change and χ tests for trend in the proportion of good perinatal outcomes among assisted reproductive technology live births (n=444,909) and liveborn singletons (n=222,500). We conducted univariable analyses followed by multiple logistic regression to estimate the effects of various characteristics on the outcome among singletons born in 2008 after fresh, nondonor assisted reproductive technology cycles (n=20,780). The proportion of good perinatal outcomes among all liveborn neonates increased from 38.6% in 2000 to 42.5% in 2008, whereas it declined marginally among singletons from 83.6% to 83.4%. One previous birth, transfer of fewer than three embryos, and the presence of fewer than three fetal hearts on 6-week ultrasound examination were associated with good perinatal outcome among singletons. Non-Hispanic black race, tubal factor infertility, uterine factor infertility, ovulatory disorder, and 5-day embryo culture were associated with reduced odds for a good outcome. The strongest association was the presence of one fetal heart compared with more than two (adjusted odds ratio 2.43, 95% confidence interval 1.73-3.42). From 2000 to 2008, good perinatal outcomes increased among assisted reproductive technology live births. Among singleton live births, odds for good outcome were greatest with the presence of a single fetal heart and lowest in women of non-Hispanic black race. II.

  16. A predictive model for assistive technology adoption for people with dementia. (United States)

    Zhang, Shuai; McClean, Sally I; Nugent, Chris D; Donnelly, Mark P; Galway, Leo; Scotney, Bryan W; Cleland, Ian


    Assistive technology has the potential to enhance the level of independence of people with dementia, thereby increasing the possibility of supporting home-based care. In general, people with dementia are reluctant to change; therefore, it is important that suitable assistive technologies are selected for them. Consequently, the development of predictive models that are able to determine a person's potential to adopt a particular technology is desirable. In this paper, a predictive adoption model for a mobile phone-based video streaming system, developed for people with dementia, is presented. Taking into consideration characteristics related to a person's ability, living arrangements, and preferences, this paper discusses the development of predictive models, which were based on a number of carefully selected data mining algorithms for classification. For each, the learning on different relevant features for technology adoption has been tested, in conjunction with handling the imbalance of available data for output classes. Given our focus on providing predictive tools that could be used and interpreted by healthcare professionals, models with ease-of-use, intuitive understanding, and clear decision making processes are preferred. Predictive models have, therefore, been evaluated on a multi-criterion basis: in terms of their prediction performance, robustness, bias with regard to two types of errors and usability. Overall, the model derived from incorporating a k-Nearest-Neighbour algorithm using seven features was found to be the optimal classifier of assistive technology adoption for people with dementia (prediction accuracy 0.84 ± 0.0242).

  17. Technology transfer of brain-computer interfaces as assistive technology: barriers and opportunities. (United States)

    Nijboer, F


    This paper provides an analysis of perspectives from different stakeholders on the state-of-the-art of BCI. Three barriers for technology transfer of BCIs as access technologies are identified. First, BCIs are developed with a narrow focus on creating a reliable technology, while a broader focus on creating a usable technology is needed. Second, the potential target group, which could benefit from BCIs as access technologies is expected to be very small. Development costs are therefore high, while reimbursements are expected to be low, which challenges the commercial viability. Third, potential target users should be much more included in the design process of BCIs to ensure that the end-products meet technical, ethical, legal and social requirements. These three issues need to be urgently addressed so that target users may benefit from this promising technology. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  18. Technology and the environment: the case for optimism

    International Nuclear Information System (INIS)

    Matt Ridley


    The author shows that the introduction of new technologies is not necessarily a threat to the environment; rather it is usually the best hope of environmental improvement. In other words, de-carbonisation of the world economy, accompanied by a shift from dirty to cleaner technologies, is occurring without any political direction. It is driven by human inventiveness. These kinds of ideas are derided by environmentalists as 'technical fixes'. They would much prefer that we cut CO 2 emissions at source. Yet actually it was technical fixes that saved the whales, the woods and the wild game before. I predict that we will survive global warming and that we will do so no thanks to treaties, global energy policies, or consumer restraint. Instead we will de-carbonise our economy with new inventions. Inventions that the environmental movement will mostly oppose. For instance, the shift to natural gas in power generation was almost universally derided by greens as a dangerous move: the notorious 'dash for gas'. Why? Gas does not need men working underground in black tunnels; it does not spill and make slicks; it is the least carbon-rich fossil fuel of all; it can be transported very cheaply in pipes; it can be burned in combined cycle turbines producing 20 or 30% more conversion efficiency than any other fuel. And, above all, it does not require the despoliation of the landscape with forests of hideous, uneconomic, unreliable, unecological, taxpayer-subsidised, concrete-hungry, golden-eagle chopping wind turbines. To replace natural gas with solar, wind, hydro or tidal power, with their insatiable demands on large acreages of our precious landscapes, would not, in my view, be green

  20. Endovascular navigation based on real/virtual environments cooperation for computer-assisted TEAM procedures (United States)

    Goksu, Cemil; Haigron, Pascal; Acosta, Oscar; Lucas, Antoine


    Transfemoral Endovascular Aneurysm Management, the less invasive treatment of Aortic Abdominal Aneurysms (AAA), is a highly specialized procedure, using advanced devices and requiring a high degree of clinical expertise. There is a great need for a navigation guidance system able to make this procedure safer and more precise. In this context of computer-assisted minimally invasive interventional procedures, we propose a new framework based on the cooperation between the real environment where the intervention takes place and a patient-specific virtual environment, which contains a virtual operating room including a C-arm model as well as the 3D preoperative patient data. This approach aims to deal with the problem of lack of knowledge about soft tissue behavior by better exploiting available information before and during the intervention through a cooperative approach. In order to assist the TEAM procedure in standard interventional conditions, we applied this framework to design a 3D navigation guidance system, which has been successfully used during three TEAM interventions in the operating room. Intra-operatively, anatomical feature-based 2D/3D registration between a single 2D fluoroscopic view, reproduced from the pose planned in the virtual environment, and the preoperative CT volume, is performed by means of a chamfer distance map. The 3D localization of the endovascular devices (sheath, guide wire, prosthesis) tracked either interactively or automatically on 2D sequences, is constrained to either the 3D vascular tree or a 3D device model. Moreover, we propose a first solution to take into account the tissue deformations during this particular intervention and to update the virtual environment with the intraoperative data.

  1. Oriented coupling of major histocompatibility complex (MHC) to sensor surfaces using light assisted immobilisation technology

    DEFF Research Database (Denmark)

    Snabe, Torben; Røder, Gustav Andreas; Neves-Petersen, Maria Teresa


    histocompatibility complex (MHC class I) to a sensor surface is presented. The coupling was performed using light assisted immobilisation--a novel immobilisation technology which allows specific opening of particular disulphide bridges in proteins which then is used for covalent bonding to thiol-derivatised surfaces...... via a new disulphide bond. Light assisted immobilisation specifically targets the disulphide bridge in the MHC-I molecule alpha(3)-domain which ensures oriented linking of the complex with the peptide binding site exposed away from the sensor surface. Structural analysis reveals that a similar...

  2. Trends of racial disparities in assisted reproductive technology outcomes in black women compared with white women: Society for Assisted Reproductive Technology 1999 and 2000 vs. 2004-2006. (United States)

    Seifer, David B; Zackula, Rosey; Grainger, David A


    To determine trends in assisted reproductive technology (ART) in black and white women by comparing Society for Assisted Reproductive Technology (SART) database outcomes for 2004-2006 with previously reported outcomes for 1999 and 2000. Retrospective, cohort study. The SART member clinics that performed at least 50 cycles of IVF and reported race in more than 95% of cycles. Women receiving 158,693 IVF cycles. In vitro fertilization using nondonor embryos. Live birth rate per cycle started. Reporting of race increased from 52% to 60%. The proportion of black, non-Hispanic (BNH) women increased from 4.6% to 6.5%. For BNH women using fresh embryos and no prior ART, significant increasing trends were observed for older age, male factor, uterine factor, diminished ovarian reserve, and ovulation disorders. The BNH women were 2.5 times more likely to have tubal factor for those cycles with no prior ART. The proportion of live births per cycle started increased across all groups over time, although greater increases occurred for white women. There seems to be widening disparities in IVF outcomes between BNH and white women, perhaps attributable to poor prognostic factors among black women. Race continues to be a marker for prognosis for ART outcomes and should be reported. Copyright 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

  3. Cross-cultural adaptation of the psychosocial impact of assistive device scale (PIADS) for Puerto Rican assistive technology users. (United States)

    Orellano, Elsa M; Jutai, Jeffrey W


    Assistive technology (AT) is important for individuals with disabilities' independence and participation in daily life, and there is a lack of valid AT outcome tools for the Puerto Rican population. This pilot study examined the content validity of a new adaptation of the Psychosocial Impact of Assistive Device Scale (PIADS): the Puerto Rican-Spanish PIADS (PR-PIADS). Following standard procedures, the cultural adaptation methodology included a bilingual multidisciplinary committee review of the original (English language) and Spanish versions of the PIADS and pilot testing of the preliminary version of the PR-PIADS with 20 AT users. The committee recommended a total of 58 semantic and conceptual modifications of the Spanish PIADS. Pilot data analysis resulted in 4 additional semantic and conceptual modifications of items that did not reach the minimum content validity ratio of 0.42 for a panel composed by 20 members: competence (0), efficiency (-0.6), performance (-0.95), and eagerness to take chances (-0.6). This pilot study demonstrated evidence of initial content validity of the PR-PIADS. Future research is required before using this tool with greater confidence to address the construct validity and reliability that are also critical to a successful cultural adaptation.

  4. Assisted reproductive technology in South Africa: first results generated from the South African Register of Assisted Reproductive Techniques. (United States)

    Dyer, Silke Juliane; Kruger, Thinus Frans


    We present the first report from the South African Register of Assisted Reproductive Techniques. All assisted reproductive technology (ART) centres in South Africa were invited to join the register. Participant centres voluntarily submitted information from 2009 on the number of ART cycles, embryo transfers, clinical pregnancies, age of female partners or egg donors, and use of fertilisation techniques. Data were anonymised, pooled and analysed. The 12 participating units conducted a total of 4 512 oocyte aspirations and 3 872 embryo transfers in 2009, resulting in 1 303 clinical pregnancies. The clinical pregnancy rate (CPR) per aspiration and per embryo transfer was 28.9% and 33.6%, respectively. Fertilisation was achieved by intracytoplasmic sperm injection in two-thirds of cycles. In most cycles, 1 - 2 embryos or blastocysts were transferred. Female age was inversely related to pregnancy rate. The register achieved a high rate of participation. The reported number of ART cycles covers approximately 6% of the estimated ART demand in South Africa. The achieved CPRs compare favourably with those reported for other countries.

  6. The expert surgical assistant. An intelligent virtual environment with multimodal input. (United States)

    Billinghurst, M; Savage, J; Oppenheimer, P; Edmond, C


    Virtual Reality has made computer interfaces more intuitive but not more intelligent. This paper shows how an expert system can be coupled with multimodal input in a virtual environment to provide an intelligent simulation tool or surgical assistant. This is accomplished in three steps. First, voice and gestural input is interpreted and represented in a common semantic form. Second, a rule-based expert system is used to infer context and user actions from this semantic representation. Finally, the inferred user actions are matched against steps in a surgical procedure to monitor the user's progress and provide automatic feedback. In addition, the system can respond immediately to multimodal commands for navigational assistance and/or identification of critical anatomical structures. To show how these methods are used we present a prototype sinus surgery interface. The approach described here may easily be extended to a wide variety of medical and non-medical training applications by making simple changes to the expert system database and virtual environment models. Successful implementation of an expert system in both simulated and real surgery has enormous potential for the surgeon both in training and clinical practice.

  7. Science, technology, environment, and competitiveness in a North American context

    Energy Technology Data Exchange (ETDEWEB)

    Trocki, L.K.


    Most economic activities pollute. Environmental regulations should serve the public good by providing incentives to reduce pollution caused by economic activity. Economic incentives include pollution taxes, subsidies for pollution abatement, and tradeable permits or allowances to pollute. Because of the political unacceptability of taxes and permits, much regulation imposes command and control measures and provides less incentive to minimize pollution. Efficient incentives would encourage pollution abatement up to the point where the cost of abatement equals the social and private benefit from the improvements in the environment. While these costs and benefits are difficult to measure, many analysts contend that the way environmental laws have been formulated and implemented in the US leads to very inefficient pollution control. This inefficiency can contribute to a decline in economic competitiveness in the long run, although economic studies do not support the ``pollution haven`` hypothesis. Better analysis (foresight) of the cost of transboundary pollution, significant in the Great Lakes region and along the US- Mexico border, as well as in rivers that flow between countries, is needed to formulate more effective policies and avoid sorry hindsight. Also, application of communal experience, technologies, and methods applied to shared problems can avoid costly duplication of searches for the optimal pollution abatement measures. 14 refs.

  9. Controlling quantum memory-assisted entropic uncertainty in non-Markovian environments (United States)

    Zhang, Yanliang; Fang, Maofa; Kang, Guodong; Zhou, Qingping


    Quantum memory-assisted entropic uncertainty relation (QMA EUR) addresses that the lower bound of Maassen and Uffink's entropic uncertainty relation (without quantum memory) can be broken. In this paper, we investigated the dynamical features of QMA EUR in the Markovian and non-Markovian dissipative environments. It is found that dynamical process of QMA EUR is oscillation in non-Markovian environment, and the strong interaction is favorable for suppressing the amount of entropic uncertainty. Furthermore, we presented two schemes by means of prior weak measurement and posterior weak measurement reversal to control the amount of entropic uncertainty of Pauli observables in dissipative environments. The numerical results show that the prior weak measurement can effectively reduce the wave peak values of the QMA-EUA dynamic process in non-Markovian environment for long periods of time, but it is ineffectual on the wave minima of dynamic process. However, the posterior weak measurement reversal has an opposite effects on the dynamic process. Moreover, the success probability entirely depends on the quantum measurement strength. We hope that our proposal could be verified experimentally and might possibly have future applications in quantum information processing.

  10. Modeling Usersr Data Traces in Multi-Resident Ambient Assisted Living Environments

    Directory of Open Access Journals (Sweden)

    Vahid Ghasemi


    Full Text Available Modeling usersr data traces is of crucial importance for human behavior analysis and context-aware applications in ambient assisted living (AAL environments. However, learning the parameters of the underlying model is a challenging task in multi-occupant environments; because, the anonymous usersr data traces are aggregated temporally. This paper proposes a novel method for modeling usersr data traces in multi-resident sensor-based AAL environments. A Markov chain was considered as the underlying model. We aimed at estimating the parameters of the Markov chain directly out of usersr aggregate data. For this purpose, we hired the idea of conditional least squares (CLS estimation. However, the CLS estimations can be inconsistent in the circumstances of AAL environments. To tackle this problem, we proposed to regularize the CLS estimations using spatial information of sensors. This information was extracted using an accessibility graph, made out of the deployed sensor network. To evaluate the proposed method, a well-known and publicly available dataset was used. The proposed method was compared with the standard CLS, using Kullback-Leibler (KL divergence, and mean squared error (MSE criteria. The results conveyed that the proposed method results in estimations with lower KL divergences from ground truth, compared to CLS. Also, the proposed method outperformed CLS with a MSE of 2.7atimes;10lsupgaminus;3l/supg.

    Although the number of elderly residents living in assisted living (AL) facilities is rising, few studies have examined the AL physical environment and its impact on resident well-being. We sought to quantify the relationship of AL physical environment with resident outcomes including neuropsychiatric symptoms (NPS), quality of life (QOL), and fall risk, and to compare the effects for demented and non-demented residents. Prospective cohort study of a stratified random sample of 326 AL residents living in 21 AL facilities. Measures included the Therapeutic Environmental Screening Scale for Nursing Homes and Residential Care (TESS-NH/RC) to rate facilities and in-person assessment of residents for diagnosis (and assessment of treatment) of dementia, ratings on standardized clinical, cognitive, and QOL measures. Regression models compared environmental measures with outcomes. TESS-NH/RC is modified into a scale for rating the AL physical environment AL-EQS. The AL Environmental Quality Score (AL-EQS) was strongly negatively associated with Neuropsychiatric Inventory (NPI) total score (p environment of AL facilities likely affects NPS and QOL in AL residents, and the effect may be stronger for residents without dementia than for residents with dementia. Environmental manipulations that increase resident privacy, as well as implementing call buttons and telephones, may improve resident well-being. Copyright © 2010 John Wiley & Sons, Ltd.

    Gaskins, Audrey J; Chiu, Yu-Han; Williams, Paige L; Ford, Jennifer B; Toth, Thomas L; Hauser, Russ; Chavarro, Jorge E


    Preconceptional folate and vitamin B-12 have been linked to beneficial reproductive outcomes in both natural pregnancies and those after assisted reproductive technology (ART) treatment. The objective of the study was to evaluate the associations of serum folate and vitamin B-12 with ART outcomes. This analysis included a random sample of 100 women (154 ART cycles) participating in a prospective cohort study [Environment and Reproductive Health (EARTH)] at the Massachusetts General Hospital Fertility Center (2007-2013). Serum folate and vitamin B-12 were measured in blood samples collected between days 3 and 9 of treatment. Generalized estimating equations with adjustment for age, BMI, and race were used to evaluate the association of serum folate and vitamin B-12 with ART outcomes. Women in the highest quartile of serum folate (>26.3 ng/mL) had 1.62 (95% CI: 0.99, 2.65) times the probability of live birth compared with women in the lowest quartile (Women in the highest quartile of serum vitamin B-12 (>701 pg/mL) had 2.04 (95% CI: 1.14, 3.62) times the probability of live birth compared with women in the lowest quartile (women with serum folate and vitamin B-12 concentrations greater than the median had 1.92 (95% CI: 1.12, 3.29) times the probability of live birth compared with women with folate and vitamin B-12 concentrations less than or equal to the median. This translated into an adjusted difference in live birth rates of 26% (95% CI: 10%, 48%; P = 0.02). Higher serum concentrations of folate and vitamin B-12 before ART treatment were associated with higher live birth rates among a population exposed to folic acid fortification.

  15. Infertility and assisted reproductive technology: the role of the perinatal social worker. (United States)

    Greenfeld, D A


    The inability to conceive a pregnancy can cause disruption and anguish to individuals and couples sharing that experience. The treatments for infertility, especially those involving assisted reproductive technology such as in vitro fertilization, can be physically, financially and emotionally stressful for participants. The impact of infertility and its treatment has introduced a new venue for perinatal social worker services to counsel, educate and support these patients.

    Cocuzza, Marcello; Cocuzza, Mariana Amora; Bragais, Frances Monette Papa; Agarwal, Ashok


    Infertility affects 10-15% of couples who are trying to conceive, and half of the cases are due to male infertility. Intracytoplasmic sperm injection is increasingly being used to overcome multiple sperm deficiencies. Due to its effectiveness, some have proposed ICSI as a solution for all cases of male infertility, regardless of the cause. Hence, even men with potentially treatable causes of infertility have sought the aid of assisted reproductive technology, rather than undergo specific ther...

  20. Using assistive technology adaptations to include students with learning disabilities in cooperative learning activities. (United States)

    Bryant, D P; Bryant, B R


    Cooperative learning (CL) is a common instructional arrangement that is used by classroom teachers to foster academic achievement and social acceptance of students with and without learning disabilities. Cooperative learning is appealing to classroom teachers because it can provide an opportunity for more instruction and feedback by peers than can be provided by teachers to individual students who require extra assistance. Recent studies suggest that students with LD may need adaptations during cooperative learning activities. The use of assistive technology adaptations may be necessary to help some students with LD compensate for their specific learning difficulties so that they can engage more readily in cooperative learning activities. A process for integrating technology adaptations into cooperative learning activities is discussed in terms of three components: selecting adaptations, monitoring the use of the adaptations during cooperative learning activities, and evaluating the adaptations' effectiveness. The article concludes with comments regarding barriers to and support systems for technology integration, technology and effective instructional practices, and the need to consider technology adaptations for students who have learning disabilities.

  1. Designing assisted living technologies 'in the wild': preliminary experiences with cultural probe methodology. (United States)

    Wherton, Joseph; Sugarhood, Paul; Procter, Rob; Rouncefield, Mark; Dewsbury, Guy; Hinder, Sue; Greenhalgh, Trisha


    There is growing interest in assisted living technologies to support independence at home. Such technologies should ideally be designed 'in the wild' i.e. taking account of how real people live in real homes and communities. The ATHENE (Assistive Technologies for Healthy Living in Elders: Needs Assessment by Ethnography) project seeks to illuminate the living needs of older people and facilitate the co-production with older people of technologies and services. This paper describes the development of a cultural probe tool produced as part of the ATHENE project and how it was used to support home visit interviews with elders with a range of ethnic and social backgrounds, family circumstances, health conditions and assisted living needs. Thirty one people aged 60 to 98 were visited in their homes on three occasions. Following an initial interview, participants were given a set of cultural probe materials, including a digital camera and the 'Home and Life Scrapbook' to complete in their own time for one week. Activities within the Home and Life Scrapbook included maps (indicating their relationships to people, places and objects), lists (e.g. likes, dislikes, things they were concerned about, things they were comfortable with), wishes (things they wanted to change or improve), body outline (indicating symptoms or impairments), home plan (room layouts of their homes to indicate spaces and objects used) and a diary. After one week, the researcher and participant reviewed any digital photos taken and the content of the Home and Life Scrapbook as part of the home visit interview. The cultural probe facilitated collection of visual, narrative and material data by older people, and appeared to generate high levels of engagement from some participants. However, others used the probe minimally or not at all for various reasons including limited literacy, physical problems (e.g. holding a pen), lack of time or energy, limited emotional or psychological resources, life events

  5. Driver trust in five driver assistance technologies following real-world use in four production vehicles. (United States)

    Kidd, David G; Cicchino, Jessica B; Reagan, Ian J; Kerfoot, Laura B


    Information about drivers' experiences with driver assistance technologies in real driving conditions is sparse. This study characterized driver interactions with forward collision warning, adaptive cruise control, active lane keeping, side-view assist, and lane departure warning systems following real-world use. Fifty-four Insurance Institute for Highway Safety employees participated and drove a 2016 Toyota Prius, 2016 Honda Civic, 2017 Audi Q7, or 2016 Infiniti QX60 for up to several weeks. Participants reported mileage and warnings from the technologies in an online daily-use survey. Participants reported their level of agreement with five statements regarding trust in an online post-use survey. Responses were averaged to create a composite measure of trust ranging from -2 (strongly disagree) to +2 (strongly agree) for each technology. Mixed-effect regression models were constructed to compare trust among technologies and separately among the study vehicles. Participants' free-response answers about what they liked least about each system were coded and examined. Participants reported driving 33,584 miles during 4 months of data collection. At least one forward collision warning was reported in 26% of the 354 daily reports. The proportion of daily reports indicating a forward collision warning was much larger for the Honda (70%) than for the Audi (18%), Infiniti (15%), and Toyota (10%). Trust was highest for side-view assist (0.98) and lowest for active lane keeping (0.20). Trust in side-view assist was significantly higher than trust in active lane keeping and lane departure warning (0.53). Trust in active lane keeping was significantly lower than trust in adaptive cruise control (0.67) and forward collision warning (0.71). Trust in adaptive cruise control was higher for the Audi (0.72) and Toyota (0.75) compared with the Honda (0.30), and significantly higher for the Infiniti (0.93). Trust in Infiniti's side-view assist (0.58) was significantly lower than

  6. Changing direction: the struggle of regulating assisted reproductive technology in Austria

    Directory of Open Access Journals (Sweden)

    Erich Griessler


    Full Text Available From 1992 until 2015, Austria had a very restrictive Reproductive Medicine Law (FMedG, 1992 that prohibited a number of treatments such as egg donation, preimplantation genetic diagnosis (PGD, heterologous sperm donation for IVF/intracytoplasmic sperm injection (ICSI as well as general access to assisted reproductive technology for same-sex couples. As one consequence of this rather prohibitive law, Austrian physicians active in the area of assisted reproductive technology co-operated with, or had daughter institutes in, countries with less restrictive legislation such as the Czech Republic and Slovakia, which are only a few hours’ drive away. For a long time, liberalisation of the Reproductive Medicine Law was blocked by the fierce and seemingly unresolvable struggle between the restrictive conservative party (ÖVP and the permissive social democrats’ party (SPÖ. In 2014 the impasse, which had lasted for decades, was finally resolved in favour of a more liberal Reproductive Medicine Law that permits egg donation, PGD in some cases and heterologous sperm donation for IVF/ICSI and lesbian couples. Assisted reproductive technology treatments for single women and surrogate motherhood remain prohibited. The new Reproductive Medicine Law was heavily opposed by the Catholic Church, by some conservatives and by disability associations. By applying the concept of political culture, this paper explains why a liberalisation of the Reproductive Medicine Law was blocked for decades, and how the sudden policy change came about.

  7. Challenges of user-centred assistive technology provision in Australia: shopping without a prescription. (United States)

    Steel, Emily J; Layton, Natasha Ann; Foster, Michele M; Bennett, Sally


    People with disability have a right to assistive technology devices and services, to support their inclusion and participation in society. User-centred approaches aim to address consumer dissatisfaction and sub-optimal outcomes from assistive technology (AT) provision, but make assumptions of consumer literacy and empowerment. Policy discourses about consumer choice prompt careful reflection, and this paper aims to provide a critical perspective on user involvement in assistive technology provision. User-centred approaches are considered, using literature to critically reflect on what user involvement means in AT provision. Challenges at the level of interactions between practitioners and consumers, and also the level of markets and policies are discussed, using examples from Australia. There is no unanimous conceptual framework for user-centred practice. Power imbalances and differing perspectives between practitioners and consumers make it difficult for consumers to feel empowered. Online access to information and international suppliers has not surmounted information asymmetries for consumers or lifted the regulation of publicly funded AT devices. Ensuring access and equity in the public provision of AT is challenging in an expanding market with diverse stakeholders. Consumers require personalised information and support to facilitate their involvement and choice in AT provision. Implications for Rehabilitation Variations in approaches informing AT provision practices have a profound impact on equity of access and outcomes for consumers. An internationalised and online market for AT devices is increasing the need for effective information provision strategies and services. Power imbalances between practitioners and consumers present barriers to the realisation of user-centred practice.

  8. Care robots for the supermarket shelf: a product gap in assistive technologies. (United States)

    Blackman, Tim


    The literature on the development of assistive robots is dominated by technological papers with little consideration of how such devices might be commercialised for a mass market at a price that is affordable for older people and their families as well as public services and care insurers. This article argues that the focus of technical development in this field is too ambitious, neglecting the potential market for an affordable device that is aleady in the realm of the 'adjacent possible' given current technology capabilities. It also questions on both ethical and marketing grounds the current effort to develop assistive robots with pet-like or human-like features. The marketing literature on 'really new products' has so far not appeared to inform the development of assistive robots but has some important lessons. These include using analogies with existing products and giving particular attention to the role of early adopters. Relevant analogies for care robots are not animals or humans but useful domestic appliances and personal technologies with attractive designs, engaging functionality and intuitive usability. This points to a strategy for enabling mass adoption - which has so far eluded even conventional telecare - of emphasising how such an appliance is part of older people's contemporary lifestyles rather than a sign of age-related decline and loss of independence.

  10. A Movement-Assisted Deployment of Collaborating Autonomous Sensors for Indoor and Outdoor Environment Monitoring. (United States)

    Niewiadomska-Szynkiewicz, Ewa; Sikora, Andrzej; Marks, Michał


    Using mobile robots or unmanned vehicles to assist optimal wireless sensors deployment in a working space can significantly enhance the capability to investigate unknown environments. This paper addresses the issues of the application of numerical optimization and computer simulation techniques to on-line calculation of a wireless sensor network topology for monitoring and tracking purposes. We focus on the design of a self-organizing and collaborative mobile network that enables a continuous data transmission to the data sink (base station) and automatically adapts its behavior to changes in the environment to achieve a common goal. The pre-defined and self-configuring approaches to the mobile-based deployment of sensors are compared and discussed. A family of novel algorithms for the optimal placement of mobile wireless devices for permanent monitoring of indoor and outdoor dynamic environments is described. They employ a network connectivity-maintaining mobility model utilizing the concept of the virtual potential function for calculating the motion trajectories of platforms carrying sensors. Their quality and utility have been justified through simulation experiments and are discussed in the final part of the paper.

  13. Co-Designing Ambient Assisted Living (AAL Environments: Unravelling the Situated Context of Informal Dementia Care

    Directory of Open Access Journals (Sweden)

    Amy S. Hwang


    Full Text Available Ambient assisted living (AAL aims to help older persons “age-in-place” and manage everyday activities using intelligent and pervasive computing technology. AAL research, however, has yet to explore how AAL might support or collaborate with informal care partners (ICPs, such as relatives and friends, who play important roles in the lives and care of persons with dementia (PwDs. In a multiphase codesign process with six (6 ICPs, we envisioned how AAL could be situated to complement their care. We used our codesigned “caregiver interface” artefacts as triggers to facilitate envisioning of AAL support and unpack the situated, idiosyncratic context within which AAL aims to assist. Our findings suggest that AAL should be designed to support ICPs in fashioning “do-it-yourself” solutions that complement tacitly improvised care strategies and enable them to try, observe, and adapt to solutions over time. In this way, an ICP could decide which activities to entrust to AAL support, when (i.e., scheduled or spontaneous and how a system should provide support (i.e., using personalized prompts based on care experience, and when adaptations to system support are needed (i.e., based alerting patterns and queried reports. Future longitudinal work employing participatory, design-oriented methods with care dyads is encouraged.

  14. A Beowulf Class parallel remote-sensed image database retrieval system developed in ASSIST environment (United States)

    Di Lecce, Vincenzo; Guerriero, Andrea; Guarino, I.


    Image databases are now currently utilized in a wide range of different areas, in particular, the development and application of remote sensing platforms result in the production of huge amounts of image data. One of the major problem in the practical implementation of a Content-based Image Retrieval (CBIR) for remotely sensed images is that the content-based indexing and searching process always requires extremely high computational power. On the other hand, the content-based image retrieval algorithms are very suitable for parallel computation as the algorithms can be broken into several data independent processes for running on a parallel computer. In this paper, we discuss the porting problem of a sequential application of remote sensed image retrieval in a parallel environment using the new paradigm of programming introduced by the birth of a new structured program languages (Assist 1.2) and compared performances to sequential and to commercial multiprocessors solutions.

    To summarize the procedures and outcomes of assisted reproductive technologies (ART) that were initiated in the United States in 2001. Data were collected electronically using the Society for Assisted Reproductive Technology (SART) Clinic Outcome Reporting System software and submitted to the American Society for Reproductive Medicine/SART Registry. Three hundred eighty-five clinics submitted data on procedures performed in 2001. Data were collated after November 2002 [corrected] so that the outcomes of all pregnancies would be known. Incidence of clinical pregnancy, ectopic pregnancy, abortion, stillbirth, and delivery. Programs reported initiating 108,130 cycles of ART treatment. Of these, 79,042 cycles involved IVF (with and without micromanipulation), with a delivery rate per retrieval of 31.6%; 340 were cycles of gamete intrafallopian transfer, with a delivery rate per retrieval of 21.9%; 661 were cycles of zygote intrafallopian transfer, with a delivery rate per retrieval of 31.0%. The following additional ART procedures were also initiated: 8,147 fresh donor oocyte cycles, with a delivery rate per transfer of 47.3%; 14,509 frozen ET procedures, with a delivery rate per transfer of 23.5%; 3,187 frozen ETs employing donated oocytes or embryos, with a delivery rate per transfer of 27.4%; and 1,366 cycles using a host uterus, with a delivery rate per transfer of 38.7%. In addition, 112 cycles were reported as combinations of more than one treatment type, 8 cycles as research, and 85 as embryo banking. As a result of all procedures, 29,585 deliveries were reported, resulting in 41,168 neonates. In 2001, there were more programs reporting ART treatment and a significant increase in reported cycles compared with 2000.

  18. Energy and the environment: Technology assessment and policy options

    International Nuclear Information System (INIS)

    Silveira, M.P.W.


    While the energy crisis of the 1970s stimulated technological innovation in developed countries, it often had the opposite effect in the third world. However, developing countries can be considered to have two types of energy systems: ''connected'' and ''disconnected''. The connected system is affected by changes in the price of commercial energy, but the disconnected system is usually rural and remote. Commercial forms of energy may be needed in the disconnected system, but they are largely unavailable. In some of the developing countries, new energy technologies have therefore been developed which adapt traditional technologies still existing in the disconnected sector. In this article some of the work of the United National Centre for Science and Technology for Development is described. Through its ATAS (Advance Technology Alert System) programme, international and regional workshops are held to discuss policy questions arising in regard to new technologies and developments. Workshops have been held in Moscow on new energy technologies in the industry subsystem (connected), in Guatemala City on new energy technologies and the disconnected system, and in Ottawa on new energy technologies, transportation and development. Initial assessments made by or through these workshops are outlined here. A fourth workshop will be held in June 1990 in Saarbrucken on energy technologies and climate change. (author). 3 figs
