High-speed civil transport flight- and propulsion-control technological issues

NASA Technical Reports Server (NTRS)

Ray, J. K.; Carlin, C. M.; Lambregts, A. A.

1992-01-01

Technology advances required in the flight and propulsion control system disciplines to develop a high speed civil transport (HSCT) are identified. The mission and requirements of the transport and major flight and propulsion control technology issues are discussed. Each issue is ranked and, for each issue, a plan for technology readiness is given. Certain features are unique and dominate control system design. These features include the high temperature environment, large flexible aircraft, control-configured empennage, minimizing control margins, and high availability and excellent maintainability. The failure to resolve most high-priority issues can prevent the transport from achieving its goals. The flow-time for hardware may require stimulus, since market forces may be insufficient to ensure timely production. Flight and propulsion control technology will contribute to takeoff gross weight reduction. Similar technology advances are necessary also to ensure flight safety for the transport. The certification basis of the HSCT must be negotiated between airplane manufacturers and government regulators. Efficient, quality design of the transport will require an integrated set of design tools that support the entire engineering design team.

In today's world, the security became the major issue to every human being. A major issue is hacking as hackers are everywhere, as the technology was developed still there are many issues where the technology fails to meet the security. Engineers, scientists were discovering the new products for security purpose as biometrics sensors like face recognition, pattern recognition, gesture recognition, voice authentication etcetera. But these devices fail to reach the expected results. In this work, we are going to present an approach to generate a unique secure key using the iris template. Here the iris templates are processed using the well-defined processing techniques. Using the encryption and decryption process they are stored, traversed and utilized. As of the work, we can conclude that the iris cryptography gives us the expected results for securing the data from eavesdroppers.

Sherkow, Jacob S

2017-11-01

Microbial technologies often serve as the basis of fundamental research tools in molecular biology. These present a variety of ethical, legal and social issues concerning their patenting. This commentary presents several case studies of these issues across three major microbiological tools: CRISPR, viral vectors and antimicrobial resistance drugs. It concludes that the development of these technologies-both scientifically and commercially-depend, in part, on the patent regime available for each, and researchers' willingness to enforce those patents against others. © FEMS 2017.

The role of ethics in information technology decisions: a case-based approach to biomedical informatics education.

PubMed

Anderson, James G

2004-03-18

The purpose of this paper is to propose a case-based approach to instruction regarding ethical issues raised by the use of information technology (IT) in healthcare. These issues are rarely addressed in graduate degree and continuing professional education programs in health informatics. There are important reasons why ethical issues need to be addressed in informatics training. Ethical issues raised by the introduction of information technology affect practice and are ubiquitous. These issues are frequently among the most challenging to young practitioners who are ill prepared to deal with them in practice. First, the paper provides an overview of methods of moral reasoning that can be used to identify and analyze ethical problems in health informatics. Second, we provide a framework for defining cases that involve ethical issues and outline major issues raised by the use of information technology. Specific cases are used as examples of new dilemmas that are posed by the introduction of information technology in healthcare. These cases are used to illustrate how ethics can be integrated with the other elements of informatics training. The cases discussed here reflect day-to-day situations that arise in health settings that require decisions. Third, an approach that can be used to teach ethics in health informatics programs is outlined and illustrated.

2015-10-21

As of 2014, the majority of the codes and standards required to initially deploy hydrogen technologies infrastructure in the United States have been promulgated. These codes and standards will be field tested through their application to actual hydrogen technologies projects. Continuous codes and standards improvement (CCSI) is a process of identifying code issues that arise during project deployment and then developing codes solutions to these issues. These solutions would typically be proposed amendments to codes and standards. The process is continuous because as technology and the state of safety knowledge develops there will be a need to monitor the applicationmore » of codes and standards and improve them based on information gathered during their application. This paper will discuss code issues that have surfaced through hydrogen technologies infrastructure project deployment and potential code changes that would address these issues. The issues that this paper will address include (1) setback distances for bulk hydrogen storage, (2) code mandated hazard analyses, (3) sensor placement and communication, (4) the use of approved equipment, and (5) system monitoring and maintenance requirements.« less

At present, most cases of unresectable cancer cannot be cured. Genetic mutations, EMT, and cancer stem cells are three major issues linked to poor prognosis in such cases, all connected by inter- and intra-tumor heterogeneity. Issues on inter-/intra-tumor heterogeneity of genetic mutation could be resolved with recent and future technologies of deep sequencers, whereas, regarding such issues as the "same genome, different epigenome/phenotype", we expect to solve many of these problems in the future through further research in stem cell biology. We herein review and discuss the three major issues in the biology of cancers, especially from the standpoint of stem cell biology.

Software reuse issues affecting AdaNET

NASA Technical Reports Server (NTRS)

Mcbride, John G.

1989-01-01

The AdaNet program is reviewing its long-term goals and strategies. A significant concern is whether current AdaNet plans adequately address the major strategic issues of software reuse technology. The major reuse issues of providing AdaNet services that should be addressed as part of future AdaNet development are identified and reviewed. Before significant development proceeds, a plan should be developed to resolve the aforementioned issues. This plan should also specify a detailed approach to develop AdaNet. A three phased strategy is recommended. The first phase would consist of requirements analysis and produce an AdaNet system requirements specification. It would consider the requirements of AdaNet in terms of mission needs, commercial realities, and administrative policies affecting development, and the experience of AdaNet and other projects promoting the transfer software engineering technology. Specifically, requirements analysis would be performed to better understand the requirements for AdaNet functions. The second phase would provide a detailed design of the system. The AdaNet should be designed with emphasis on the use of existing technology readily available to the AdaNet program. A number of reuse products are available upon which AdaNet could be based. This would significantly reduce the risk and cost of providing an AdaNet system. Once a design was developed, implementation would proceed in the third phase.

Vaccines for HIV | NCI Technology Transfer Center | TTC

Cancer.gov

The development of an effective HIV vaccine has been an ongoing area of research. The high variability in HIV-1 virus strains has represented a major challenge in successful development. Ideally, an effective candidate vaccine would provide protection against the majority of clades of HIV. Two major hurdles to overcome are immunodominance and sequence diversity. This vaccine utilizes a strategy for overcoming these two issues by identifying the conserved regions of the virus and exploiting them for use in a targeted therapy. NCI seeks licensees and/or research collaborators to commercialize this technology, which has been validated in macaque models.

Background Technology has changed the landscape in which psychiatry operates. Effective, evidence-based treatments for mental health care are now available at the fingertips of anyone with Internet access. However, technological solutions for mental health are not necessarily sought by consumers nor recommended by clinicians. Objective The objectives of this study are to identify and discuss the barriers to introducing eHealth technology-supported interventions within mental health. Methods An interactive polling tool was used to ask “In this brave new world, what are the key issues that need to be addressed to improve mental health (using technology)?” Respondents were the multidisciplinary attendees of the “Humans and Machines: A Quest for Better Mental Health” conference, held in Sydney, Australia, in 2016. Responses were categorized into 10 key issues using team-based qualitative analysis. Results A total of 155 responses to the question were received from 66 audience members. Responses were categorized into 10 issues and ordered by importance: access to care, integration and collaboration, education and awareness, mental health stigma, data privacy, trust, understanding and assessment of mental health, government and policy, optimal design, and engagement. In this paper, each of the 10 issues are outlined, and potential solutions are discussed. Many of the issues were interrelated, having implications for other key areas identified. Conclusions As many of the issues identified directly related to barriers to care, priority should be given to addressing these issues that are common across mental health delivery. Despite new challenges raised by technology, technology-supported mental health interventions represent a tremendous opportunity to address in a timely way these major concerns and improve the receipt of effective, evidence-based therapy by those in need.

High-speed civil transport issues and technology program

NASA Technical Reports Server (NTRS)

Hewett, Marle D.

1992-01-01

A strawman program plan is presented, consisting of technology developments and demonstrations required to support the construction of a high-speed civil transport. The plan includes a compilation of technology issues related to the development of a transport. The issues represent technical areas in which research and development are required to allow airframe manufacturers to pursue an HSCT development. The vast majority of technical issues presented require flight demonstrated and validated solutions before a transport development will be undertaken by the industry. The author believes that NASA is the agency best suited to address flight demonstration issues in a concentrated effort. The new Integrated Test Facility at NASA Dryden Flight Research Facility is considered ideally suited to the task of supporting ground validations of proof-of-concept and prototype system demonstrations before night demonstrations. An elaborate ground hardware-in-the-loop (iron bird) simulation supported in this facility provides a viable alternative to developing an expensive fill-scale prototype transport technology demonstrator. Drygen's SR-71 assets, modified appropriately, are a suitable test-bed for supporting flight demonstrations and validations of certain transport technology solutions. A subscale, manned or unmanned flight demonstrator is suitable for flight validation of transport technology solutions, if appropriate structural similarity relationships can be established. The author contends that developing a full-scale prototype transport technology demonstrator is the best alternative to ensuring that a positive decision to develop a transport is reached by the United States aerospace industry.

In the USA, women have consistently been proportionally underrepresented in science and technology (S&T). In these disciplines, as students move from high schools to colleges to graduate programs, qualified women drop out at higher rates than do men, resulting in a striking loss of talented students. Attitude toward a discipline is one of the major factors in students' choice of majors. As a result, attitudes toward S&T are issues with longstanding attention and interest in education research. Retention of female students in S&T majors remains a major concern. The purpose of the study was to investigate attitudes toward S&T including attitudes toward female participation in S&T, among S&T majors, and examine differences by gender and class standing. Such an investigation would provide deeper insights to help devise strategies to retain women in S&T majors.

Mobility technologies, including wheelchairs, prostheses, joint replacements, assistive devices, and therapeutic exercise equipment help millions of people participate in desired life activities. Yet, these technologies are not yet fully transformative because many desired activities cannot be pursued or are difficult to pursue for the millions of individuals with mobility related impairments. This WTEC study, initiated and funded by the National Science Foundation, was designed to gather information on European innovations and trends in technology that might lead to greater mobility for a wider range of people. What might these transformative technologies be and how might they arise? Based on visits to leading mobility technology research labs in western Europe, the WTEC panel identified eight major trends in mobility technology research. This commentary summarizes these trends, which are then described in detail in companion papers appearing in this special issue.

Lineage in the Islamic law is one of the most basic human rights each individual inherits from his family. When modern assisted reproductive technologies appeared in recent decades, the issue of lineage and the child's rights did not encounter serious challenges. But with the advent of these technologies, the issue of the child's lineage resulting from new technologies has become the center of attention. These technologies have a large share in the field of medicine. A new technique known as cloning has entered the realm of science and technology. Considering the possibility of the widespread use of this technique, the subject of cloned child's lineage and his/her rights would be one of the major issues related to this subject. In this paper, the authors have examined the various aspects of the subject and the opinions of theologians in this regard in order to present a best solution to this issue. In fact, the fundamental concern in this paper is to figure out the relationship between the cloned child, the cell donor, the egg donor and the owner of the uterus. In this paper, after considering the concepts of the parentage and identical twins’ relationship would be explored and then a detailed analysis of the parental relationship and the Shiite jurisprudence scholars' opinion on these issues would be presented. Finally, the rights of cloned children would be taken into consideration. PMID:23926545

We review technical and sociological issues facing the Life Sciences as they transform into more data-centric disciplines - the "Big New Biology". Three major challenges are: 1) lack of comprehensive standards; 2) lack of incentives for individual scientists to share data; 3) lack of appropriate infrastructure and support. Technological advances with standards, bandwidth, distributed computing, exemplar successes, and a strong presence in the emerging world of Linked Open Data are sufficient to conclude that technical issues will be overcome in the foreseeable future. While motivated to have a shared open infrastructure and data pool, and pressured by funding agencies in move in this direction, the sociological issues determine progress. Major sociological issues include our lack of understanding of the heterogeneous data cultures within Life Sciences, and the impediments to progress include a lack of incentives to build appropriate infrastructures into projects and institutions or to encourage scientists to make data openly available.

Wireless technology in disease management and medicine.

PubMed

Clifford, Gari D; Clifton, David

2012-01-01

Healthcare information, and to some extent patient management, is progressing toward a wireless digital future. This change is driven partly by a desire to improve the current state of medicine using new technologies, partly by supply-and-demand economics, and partly by the utility of wireless devices. Wired technology can be cumbersome for patient monitoring and can restrict the behavior of the monitored patients, introducing bias or artifacts. However, wireless technologies, while mitigating some of these issues, have introduced new problems such as data dropout and "information overload" for the clinical team. This review provides an overview of current wireless technology used for patient monitoring and disease management. We identify some of the major related issues and describe some existing and possible solutions. In particular, we discuss the rapidly evolving fields of telemedicine and mHealth in the context of increasingly resource-constrained healthcare systems.

Foetal images: the power of visual technology in antenatal care and the implications for women's reproductive freedom.

PubMed

Zechmeister, I

2001-01-01

Continuing medico-technical progress has led to an increasing medicalisation of pregnancy and childbirth. One of the most common technologies in this context is ultrasound. Based on some identified 'pro-technology feminist theories', notably the postmodernist feminist discourse, the technology of ultrasound is analysed focusing mainly on social and political rather than clinical issues. As empirical research suggests, ultrasound is welcomed by the majority of women. The analysis, however, shows that attitudes and decisions of women are influenced by broader social aspects. Furthermore, it demonstrates how the visual technology of ultrasound, in addition to other reproductive technology in maternity care, is linked to the 'personification' of the foetus and has therefore contributed to a new image of the foetus. The exploration of these issues challenges some arguments of feminist discourse. It draws attention to possible adverse implications of the technology for women's reproductive freedom and indicates the importance of the topic for political discussions.

Harmon, S. Y.

1987-02-01

This paper describes the design of an autonomous vehicle and the lessons learned during the implementation of that complex robot. The major problems encountered to which solutions were found include sensor processing bandwidth limitations, coordination of the interactions between major subsystems, sensor data fusion and system knowledge representation. Those problems remaining unresolved include system complexity management, the lack of powerful system monitoring and debugging tools, exploratory implementation of a complex system and safety and testing issues. Many of these problems arose from working with underdeveloped and continuously evolving technology and will probably be resolved as the technological resources mature and stabilize. Unfortunately, other problems will continue to plague developers throughout the evolution of autonomous system technology.

The effective care and support of community healthcare nurses (CHNs) contribute greatly to the healthy aging of older adults living at home. Integrating innovative technologies into CHNs' daily practice offers new opportunities and perspectives for early detection of health issues and interventions among home-dwelling older adults. To explore the perception of acceptability among CHNs of an intelligent wireless sensor system (IWSS) for use in daily practice for the detection of health issues in home-dwelling older adults receiving home healthcare. Descriptive and qualitative data were sourced from a pilot randomized controlled trial involving 17 CHNs using an IWSS in their daily practice to rapidly detect falls and other health issues in patients' homes. IWSS alerts indicating behavior changes were sent to CHNs. Their perceived usefulness (PU) and perceived ease of use (PEOU) were assessed. The acceptability of IWSS technology was explored using a questionnaire and focus group discussions. The PU and PEOU of the IWSS technology were low to moderate. A majority of the CHNs were dissatisfied with its performance and intrusiveness; they reported multiple obstacles in the usefulness and ease of use of the IWSS technology in daily practice. To improve the IWSS technology's low to moderate acceptability among CHNs, we recommend a more user-centered implementation strategy and an embedded model of nursing care.

One of the major issues with technology in general, and nanotechnology in particular, is that it could exacerbate the divide between developed and developing nations. If the benefits of the research do not flow beyond the national and geographical borders of the traditional major bastions of R&D, these benefits will not be equally and globally available. The consequence is that the technological divide becomes wider at the expense of mutual reliance. As much as developed nations need to rethink the strategy and the policy to bring nanotechnology products to market with the goal of global prosperity, developing nations cannot afford to simply wait for the lead from the developed nations. In the spirit of collaboration and collegiality, we describe issues with the current practices in nanotechnology R&D in the developing world and suggest a path for nanotechnology research in energy, water and the environment that developing nations could follow in order to become contributors rather than simply consumers.

Technology has changed the landscape in which psychiatry operates. Effective, evidence-based treatments for mental health care are now available at the fingertips of anyone with Internet access. However, technological solutions for mental health are not necessarily sought by consumers nor recommended by clinicians. The objectives of this study are to identify and discuss the barriers to introducing eHealth technology-supported interventions within mental health. An interactive polling tool was used to ask "In this brave new world, what are the key issues that need to be addressed to improve mental health (using technology)?" Respondents were the multidisciplinary attendees of the "Humans and Machines: A Quest for Better Mental Health" conference, held in Sydney, Australia, in 2016. Responses were categorized into 10 key issues using team-based qualitative analysis. A total of 155 responses to the question were received from 66 audience members. Responses were categorized into 10 issues and ordered by importance: access to care, integration and collaboration, education and awareness, mental health stigma, data privacy, trust, understanding and assessment of mental health, government and policy, optimal design, and engagement. In this paper, each of the 10 issues are outlined, and potential solutions are discussed. Many of the issues were interrelated, having implications for other key areas identified. As many of the issues identified directly related to barriers to care, priority should be given to addressing these issues that are common across mental health delivery. Despite new challenges raised by technology, technology-supported mental health interventions represent a tremendous opportunity to address in a timely way these major concerns and improve the receipt of effective, evidence-based therapy by those in need. ©Jennifer Nicholas, Kit Huckvale, Mark Erik Larsen, Ashna Basu, Philip J Batterham, Frances Shaw, Shahbaz Sendi.

Some of the ethical, environmental and social issues relating to the design and use of machine vision systems in manufacturing industry are highlighted. The authors' aim is to emphasize some of the more important issues, and raise general awareness of the need to consider the potential advantages and hazards of machine vision technology. However, in a short article like this, it is impossible to cover the subject comprehensively. This paper should therefore be seen as a discussion document, which it is hoped will provoke more detailed consideration of these very important issues. It follows from an article presented at last year's workshop. Five major topics are discussed: (1) The impact of machine vision systems on the environment; (2) The implications of machine vision for product and factory safety, the health and well-being of employees; (3) The importance of intellectual integrity in a field requiring a careful balance of advanced ideas and technologies; (4) Commercial and managerial integrity; and (5) The impact of machine visions technology on employment prospects, particularly for people with low skill levels.

Boeing's program for Advanced Technology Composite Aircraft Structure (ATCAS) has focused on the manufacturing and performance issues associated with a wide body commercial transport fuselage. The primary goal of ATCAS is to demonstrate cost and weight savings over a 1995 aluminum benchmark. A 31 foot section of fuselage directly behind the wing to body intersection was selected for study purposes. This paper summarizes ATCAS contract plans and review progress to date. The six year ATCAS program will study technical issues for crown, side, and keel areas of the fuselage. All structural details in these areas will be included in design studies that incorporate a design build team (DBT) approach. Manufacturing technologies will be developed for concepts deemed by the DBT to have the greatest potential for cost and weight savings. Assembly issues for large, stiff, quadrant panels will receive special attention. Supporting technologies and mechanical tests will concentrate on the major issues identified for fuselage. These include damage tolerance, pressure containment, splices, load redistribution, post-buckled structure, and durability/life. Progress to date includes DBT selection of baseline fuselage concepts; cost and weight comparisons for crown panel designs; initial panel fabrication for manufacturing and structural mechanics research; and toughened material studies related to keel panels. Initial ATCAS studies have shown that NASA's Advanced Composite Technology program goals for cost and weight savings are attainable for composite fuselage.

Nutrigenomics: the cutting edge and Asian perspectives.

PubMed

Kato, Hisanori

2008-01-01

One of the two major goals of nutrigenomics is to make full use of genomic information to reveal how genetic variations affect nutrients and other food factors and thereby realize tailor-made nutrition (nutrigenetics). The other major goal of nutrigenomics is to comprehensively understand the response of the body to diets and food factors through various 'omics' technologies such as transcriptomics, proteomics, and metabolomics. The most successfully exploited technology to date is transcriptome analysis, due mainly to its efficiency and high-throughput feature. This technology has already provided a substantial amount of data on, for instance, the novel function of food factors, the unknown mechanism of the effect of nutrients, and even safety issues of foods. The nutrigenomics database that we have created now holds the publication data of several hundred of such 'omics' studies. Furthermore, the transcriptomics approach is being applied to food safety issues. For ex-ample, the data we have obtained thus far suggest that this new technology will facilitate the safety evaluation of newly developed foods and will help clarify the mechanism of toxic effects resulting from the excessive intake of a nutrient. The 'omics' data accumulated by our group and others strongly support the promise of the systems biology approach to food and nutrition science.

1977-01-01

This report presents an initial evaluation of the major health and environmental issues associated with increased coal use in the six midwestern states of Illinois, Indiana, Michigan, Minnesota, Ohio, and Wisconsin. Using an integrated assessment approach, the evaluation proceeds from a base-line scenario of energy demand and facility siting for 1975-2020. Emphasis is placed on impacts from coal extraction, land reclamation, coal combustion for electrical generation, and coal gasification. The range of potential impacts and constraints is illustrated by a second scenario that represents an expected upper limit for coal utilization in Illinois. The following are among the more significantmore » issues identified and evaluated in this study: If environmental and related issues can be resolved, coal will continue to be a major source of energy for the Midwest; existing sulfur emission constraints will increase use of western coal; the resource requirements and environmental impacts of coal utilization will require major significant environmental and economic tradeoffs in site selection; short-term (24-hr) ambient standards for sulfur dioxide will limit the sizes of coal facilities or require advanced control technologies; an impact on public health may result from long-range transport of airborne sulfur emissions from coal facilities in the Midwest; inadequately controlled effluents from coal gasification may cause violations of water-quality standards; the major ecological effects of coal extraction are from pre-mining and post-reclamation land use; and sulfur dioxide is the major potential contributor to effects on vegetation of atmospheric emissions from coal facilities.« less

Mobile satellite communications technology - A summary of NASA activities

NASA Technical Reports Server (NTRS)

Dutzi, E. J.; Knouse, G. H.

1986-01-01

Studies in recent years indicate that future high-capacity mobile satellite systems are viable only if certain high-risk enabling technologies are developed. Accordingly, NASA has structured an advanced technology development program aimed at efficient utilization of orbit, spectrum, and power. Over the last two years, studies have concentrated on developing concepts and identifying cost drivers and other issues associated with the major technical areas of emphasis: vehicle antennas, speech compression, bandwidth-efficient digital modems, network architecture, mobile satellite channel characterization, and selected space segment technology. The program is now entering the next phase - breadboarding, development, and field experimentation.

The Importance of Technology Readiness in NASA Earth Venture Missions

NASA Technical Reports Server (NTRS)

Wells, James E.; Komar, George J.

2009-01-01

The first set of Venture-class investigations share the characteristic that the technology should be mature and all investigations must use mature technology that has been modeled or demonstrated in a relevant environment (Technology Readiness Level (TRL) >5). Technology Readiness Levels are a systematic metric/measurement system that supports assessments of the maturity of a particular technology and the consistent comparison of maturity between different types of technology. The TRL is used in NASA technology planning. A major step in the level of fidelity of the technology demonstration follows the completion of TRL 5. At TRL 6, a system or subsystem model or prototype must be demonstrated in a relevant environment (ground or space) representative model or prototype system or system, which would go well beyond ad hoc, "patch-cord," or discrete component level breadboarding. These TRL levels are chosen as target objectives for the Program. The challenge for offerors is that they must identify key aspects (uncertainty, multi subsystem complexity, etc) of the TRL estimate that should be properly explained in a submitted proposal. Risk minimization is a key component of the Earth Venture missions. Experiences of prior airborne missions will be shared. The discussion will address aspects of uncertainty and issues surrounding three areas of airborne earth science missions: (1) Aircraft or proposed flight platform -- Expressing the capability of the aircraft in terms of the supporting mission requirements. These issues include airplane performance characteristics (duration, range, altitude, among others) and multiship complexities. (2) Instruments -- Establishing that the instruments have been demonstrated in a relevant environment. Instruments with heritage in prior space missions meet this requirement, as do instruments tested on the ground. Evidence that the instruments have demonstrated the ability to collect data as advertised will be described. The complexity of the integration of multiple subsystems will also be addressed. Issues associated with tailoring the instrument to meet the specific Venture mission objectives must be thoroughly explained and justified. (3) Aircraft/Instrument Integration -- Explicitly defining what development may be required to harden the instrument and integrate the instrument. The challenges associated with this key aspect of major airborne earth science investigations will be presented.

An assessment of advanced displays and controls technology applicable to future space transportation systems

NASA Technical Reports Server (NTRS)

Hatfield, Jack J.; Villarreal, Diana

1990-01-01

The topic of advanced display and control technology is addressed along with the major objectives of this technology, the current state of the art, major accomplishments, research programs and facilities, future trends, technology issues, space transportation systems applications and projected technology readiness for those applications. The holes that may exist between the technology needs of the transportation systems versus the research that is currently under way are addressed, and cultural changes that might facilitate the incorporation of these advanced technologies into future space transportation systems are recommended. Some of the objectives are to reduce life cycle costs, improve reliability and fault tolerance, use of standards for the incorporation of advancing technology, and reduction of weight, volume and power. Pilot workload can be reduced and the pilot's situational awareness can be improved, which would result in improved flight safety and operating efficiency. This could be accomplished through the use of integrated, electronic pictorial displays, consolidated controls, artificial intelligence, and human centered automation tools. The Orbiter Glass Cockpit Display is an example examined.

Energy, Society, and Education, with Emphasis on Educational Technology Policy for K-12

NASA Astrophysics Data System (ADS)

Chedid, Loutfallah Georges

2005-03-01

This paper begins by examining the profound impact of energy usage on our lives, and on every major sector of the economy. Then, the anticipated US energy needs by the year 2025 are presented based on the Department of Energy's projections. The paper considers the much-touted National Energy Policy Report, and identifies a major flaw where the policy report neglects education as a contributor to solving future energy problems. The inextricable interaction between energy solutions and education is described, with emphasis on education policy as a potential vehicle for developing economically and commercially sustainable energy systems that have a minimal impact on the environment. With that said, an earnest argument is made as to the need to educate science, technology, engineering, and mathematics (STEM) proficient individuals for the energy technology development workforce, starting with the K-12 level. A framework for the aforementioned STEM education policies is presented that includes a sustained national awareness campaign, address the teacher's salary issues, and addresses teacher quality issues. Moreover, the framework suggests a John Dewey-style "learning-by-doing" shift in pedagogy. Finally, the framework presents specific changes to the current national standards that would be valuable to the 21st century student.

Transfer and utilization of government technology assets to the private sector in the fields of health care and information technologies

NASA Astrophysics Data System (ADS)

Kun, Luis G.

1995-10-01

During the first Health Care Technology Policy conference last year, during health care reform, four major issues were brought up in regards to the efforts underway to develop a computer based patient record (CBPR), the National Information Infrastructure (NII) as part of the high performance computers and communications (HPCC), and the so-called 'patient card.' More specifically it was explained how a national information system will greatly affect the way health care delivery is provided to the United States public and reduce its costs. These four issues were: (1) Constructing a national information infrastructure (NII); (2) Building a computer based patient record system; (3) Bringing the collective resources of our national laboratories to bear in developing and implementing the NII and CBPR, as well as a security system with which to safeguard the privacy rights of patients and the physician-patient privilege; (4) Utilizing government (e.g., DOD, DOE) capabilities (technology and human resources) to maximize resource utilization, create new jobs, and accelerate technology transfer to address health care issues. This year a section of this conference entitled: 'Health Care Technology Assets of the Federal Government' addresses benefits of the technology transfer which should occur for maximizing already developed resources. This section entitled: 'Transfer and Utilization of Government Technology Assets to the Private Sector,' will look at both health care and non-health care related technologies since many areas such as information technologies (i.e. imaging, communications, archival/retrieval, systems integration, information display, multimedia, heterogeneous data bases, etc.) already exist and are part of our national labs and/or other federal agencies, i.e., ARPA. These technologies although they are not labeled under health care programs they could provide enormous value to address technical needs. An additional issue deals with both the technical (hardware, software) and human expertise that resides within these labs and their possible role in creating cost effective solutions.

The future of acoustics distance education at Penn State

NASA Astrophysics Data System (ADS)

Brooks, Karen P.; Sparrow, Victor W.; Atchley, Anthony A.

2005-04-01

For nearly 20 years Penn State's Graduate Program in Acoustics has offered a graduate distance education program, established in response to Department of Defense needs. Using satellite technology, courses provided synchronous classes incorporating one-way video and two-way audio. Advancements in technology allowed more sophisticated delivery systems to be considered and courses to be offered to employees of industry. Current technology utilizes real time video-streaming and archived lectures to enable individuals anywhere to access course materials. The evolution of technology, expansion of the geographic market and changing needs of the student, among other issues, require a new paradigm. This paradigm must consider issues such as faculty acceptance and questions facing all institutions with regard to blurring the distinction between residence and distance education. Who will be the students? What will be the purpose of education? Will it be to provide professional and/or research degrees? How will the Acoustics Program ensure it remains attractive to all students, while working within the boundaries and constraints of a major research university? This is a look at current practice and issues with an emphasis on those relevant to constructing the Acoustics Programs distance education strategy for the future.

Acceptability Among Community Healthcare Nurses of Intelligent Wireless Sensor-system Technology for the Rapid Detection of Health Issues in Home-dwelling Older Adults

Cohen, Christine; Kampel, Thomas; Verloo, Henk

2017-01-01

Background: The effective care and support of community healthcare nurses (CHNs) contribute greatly to the healthy aging of older adults living at home. Integrating innovative technologies into CHNs’ daily practice offers new opportunities and perspectives for early detection of health issues and interventions among home-dwelling older adults. Aim: To explore the perception of acceptability among CHNs of an intelligent wireless sensor system (IWSS) for use in daily practice for the detection of health issues in home-dwelling older adults receiving home healthcare. Method: Descriptive and qualitative data were sourced from a pilot randomized controlled trial involving 17 CHNs using an IWSS in their daily practice to rapidly detect falls and other health issues in patients’ homes. IWSS alerts indicating behavior changes were sent to CHNs. Their perceived usefulness (PU) and perceived ease of use (PEOU) were assessed. The acceptability of IWSS technology was explored using a questionnaire and focus group discussions. Results: The PU and PEOU of the IWSS technology were low to moderate. A majority of the CHNs were dissatisfied with its performance and intrusiveness; they reported multiple obstacles in the usefulness and ease of use of the IWSS technology in daily practice. Conclusion: To improve the IWSS technology’s low to moderate acceptability among CHNs, we recommend a more user-centered implementation strategy and an embedded model of nursing care. PMID:28567170

Naisbitt, J.

1978-01-01

Using a special analytical procedure for tracking and assessing events reported in the nation's newspapers, the Center for Policy Process has identified ten emerging trends in the United States that are having a major impact on all our lives and on all businesses and industries--and especially on the electric utility industry. Although the trends may move in contradictory directions and have different degrees of significance, all have been carefully monitored for a considerable length of time. All are firmly established--and are not to be viewed as the momentary interests of certain radical elements of the population. The ten trends are:more » the fast-emerging clash between nuclear fuel and coal as an environmental health issue; displacement of racism and sexism by ''ageism'' as society's most prominent anti-discrimination preoccupation, and the complete elimination soon of mandatory retirement; in government and technology, the phenomenon of ''appropriate scale'' replacing economies of scale, emergence of single-issue political organizations; coming-of-age of the recycling ethic; emergence of ''access to capital'' as the new equity issue--the new rights issue; continuing shift from centralization to decentralization; movement of society in the dual directions of high technology/high touch; business' increasing involvement with the well-established accountability trend; and shift from a representative democracy to a participatory democracy--this profound change in American democracy actually began about a decade or so ago.« less

The new genetic technologies are becoming increasingly applicable to clinical medicine. At present, however, diagnostic capabilities far exceed treatment options. Pregnancy termination, with its attendant moral-ethical problems, remains the major therapeutic option for mothers bearing fetuses with genetic abnormalities. In this article, the author outlines the major ethical issues facing family physicians, in the context of our expanding genetic diagnostic and therapeutic capabilities, and their possible effects on the traditional physician-patient relationship.

Major transitions in information technology

PubMed Central

Valverde, Sergi

2016-01-01

When looking at the history of technology, we can see that all inventions are not of equal importance. Only a few technologies have the potential to start a new branching series (specifically, by increasing diversity), have a lasting impact in human life and ultimately became turning points. Technological transitions correspond to times and places in the past when a large number of novel artefact forms or behaviours appeared together or in rapid succession. Why does that happen? Is technological change continuous and gradual or does it occur in sudden leaps and bounds? The evolution of information technology (IT) allows for a quantitative and theoretical approach to technological transitions. The value of information systems experiences sudden changes (i) when we learn how to use this technology, (ii) when we accumulate a large amount of information, and (iii) when communities of practice create and exchange free information. The coexistence between gradual improvements and discontinuous technological change is a consequence of the asymmetric relationship between complexity and hardware and software. Using a cultural evolution approach, we suggest that sudden changes in the organization of ITs depend on the high costs of maintaining and transmitting reliable information. This article is part of the themed issue ‘The major synthetic evolutionary transitions’. PMID:27431527

2015-01-01

Advances in information and communication technology have facilitated the development of online psychotherapy. This form of psychotherapy would provide the developing world with better access to professional mental healthcare services. At the same time, it is prudent to carefully consider the various ethical, legal and regulatory issues involved in online psychotherapy. This paper highlights the major ethical issues involved in the use of online psychotherapy, whether conducted via e-mail, chat rooms or interactive video, and identifies practical solutions for the ethical dilemmas that exist. Many authors and organisations have expressed their opinions on the subject, but no consensus has evolved. The advice offered to psychologists is mostly skewed and the scarcity of literature available to those considering expanding their practice to include online psychotherapy is certainly a source of vexation. While reviewing the existing literature, this paper seeks to describe and discuss the major ethical issues in this area, particularly in India, but many of these issues will be equally applicable to any developing world settings.

Strategic defense initiative: critical issues

DOE Office of Scientific and Technical Information (OSTI.GOV)

Nuckolls, J.H.

The objectives of the Strategic Defense Initiative (SDI) as outlined by President Reagan are discussed. The principal objective for SDI is as a defense against ballistic missiles. Soviet objections and a summary of US-USSR dialogue on the subject are reviewed. Most US studies have been critical of SDI. Four critical issues are addressed in depth: are defense weapons technologically feasible which have high economic leverage relative to offensive ballistic missiles; would the defense feasibility and leverage be degraded or enhanced in the technological race between weapons innovation and countermeasures; could stability be achieved during and after the transition to themore » defense dominated world envisioned by SDI proponents; would the deployment of high leverage defensive weapons increase or decrease the security of NATO Europe, and the probability of major conventional or nuclear wars. The issue of SDI may lead to a paradox that contains the seeds of catastrophe. The author concludes by warning that nuclear disarmament may eliminate the highly successful deterrent mechanism for avoiding another major world war. In a world made safe for major conventional wars by the apparent ''elimination'' of nuclear weapons, the leaders in a conventional World War III - involving unimaginable suffering, hatred, terror, and death - would be strongly motivated to introduce nuclear weapons in the crucial decisive battles. Even if diplomacy could ''eliminate'' nuclear weapons, man's knowledge of nuclear weapons can never be eliminated. The paradox is the attempt to eliminate nuclear weapons may maximize the probability of their use. (DMC)« less

Managing information technology human resources in health care.

PubMed

Mahesh, Sathiadev; Crow, Stephen M

2012-01-01

The health care sector has seen a major increase in the use of information technology (IT). The increasing permeation of IT into the enterprise has resulted in many non-IT employees acquiring IT-related skills and becoming an essential part of the IT-enabled enterprise. Health care IT employees work in a continually changing environment dealing with new specializations that are often unfamiliar to other personnel. The widespread use of outsourcing and offshoring in IT has introduced a third layer of complexity in the traditional hierarchy and its approach to managing human resources. This article studies 3 major issues in managing these human resources in an IT-enabled health care enterprise and recommends solutions to the problem.

Stability issues pertaining large area perovskite and dye-sensitized solar cells and modules

Perovskite and dye-sensitized solar cells are PV technologies which hold promise for PV application. Arguably, the biggest issue facing these technologies is stability. The vast majority of studies have been limited to small area laboratory cells. Moisture, oxygen, UV light, thermal and electrical stresses are leading the degradation causes. There remains a shortage of stability investigations on large area devices, in particular modules. At the module level there exist particular challenges which can be different from those at the small cell level such as encapsulation (not only of the unit cells but of interconnections and contacts), non-uniformity of the layer stacks and unit cells, reverse bias stresses, which are important to investigate for technologies that aim for industrial acceptance. Herein we present a review of stability investigations published in the literature pertaining large area perovskite and dye-sensitized solar devices fabricated both on rigid (glass) and flexible substrates.

Major technology issues in surgical data collection.

PubMed

Kirschenbaum, I H

1995-10-01

Surgical scheduling and data collection is a field that has a long history as well as a bright future. Historically, surgical cases have always involved some amount of data collection. Surgical cases are scheduled and then reviewed. The classic method, that large black surgical log, actually still exists in many hospitals. In fact, there is nothing new about the recording or reporting of surgical cases. If we only needed to record the information and produce a variety of reports on the data, then modern electronic technology would function as a glorified fast index card box--or, in computer database terms, a simple flat file database. But, this is not the future of technology in surgical case management. This article makes the general case for integrating surgical data systems. Instead of reviewing specific software, it essentially addresses the issues of strategic planning related to this important aspect of medical information systems.

Many issues need to be resolved for a production-worthy model based assist feature insertion flow for single and double exposure patterning process to extend low k1 process at 193 nm immersion technology. Model based assist feature insertion is not trivial to implement either for single and double exposure patterning compared to rule based methods. As shown in Fig. 1, pixel based mask inversion technology in itself has difficulties in mask writing and inspection although it presents as one of key technology to extend single exposure for contact layer. Thus far, inversion technology is tried as a cooptimization of target mask to simultaneously generate optimized main and sub-resolution assists features for a desired process window. Alternatively, its technology can also be used to optimize for a target feature after an assist feature types are inserted in order to simplify the mask complexity. Simplification of inversion mask is one of major issue with applying inversion technology to device development even if a smaller mask feature can be fabricated since the mask writing time is also a major factor. As shown in Figure 2, mask writing time may be a limiting factor in determining whether or not an inversion solution is viable. It can be reasoned that increased number of shot counts relates to increase in margin for inversion methodology. On the other hand, there is a limit on how complex a mask can be in order to be production worthy. There is also source and mask co-optimization which influences the final mask patterns and assist feature sizes and positions for a given target. In this study, we will discuss assist feature insertion methods for sub 40-nm technology.

Autonomy, Automation, and Systems

Aerospace industry interest in autonomy and automation, given fresh impetus by the national goal of establishing a Space Station, is becoming a major item of research and technology development. The promise of new technology arising from research in Artificial Intelligence (AI) has focused much attention on its potential in autonomy and automation. These technologies can improve performance in autonomous control functions that involve planning, scheduling, and fault diagnosis of complex systems. There are, however, many aspects of system and subsystem design in an autonomous system that impact AI applications, but do not directly involve AI technology. Development of a system control architecture, establishment of an operating system within the design, providing command and sensory data collection features appropriate to automated operation, and the use of design analysis tools to support system engineering are specific examples of major design issues. Aspects such as these must also receive attention and technology development support if we are to implement complex autonomous systems within the realistic limitations of mass, power, cost, and available flight-qualified technology that are all-important to a flight project.

Health care information infrastructure: what will it be and how will we get there?

During the first Health Care Technology Policy [HCTPI conference last year, during Health Care Reform, four major issues were brought up in regards to the underway efforts to develop a Computer Based Patient Record (CBPR)I the National Information Infrastructure (NIl) as part of the High Performance Computers & Communications (HPCC), and the so-called "Patient Card" . More specifically it was explained how a national information system will greatly affect the way health care delivery is provided to the United States public and reduce its costs. These four issues were: Constructing a National Information Infrastructure (NIl); Building a Computer Based Patient Record System; Bringing the collective resources of our National Laboratories to bear in developing and implementing the NIl and CBPR, as well as a security system with which to safeguard the privacy rights of patients and the physician-patient privilege; Utilizing Government (e.g. DOD, DOE) capabilities (technology and human resources) to maximize resource utilization, create new jobs and accelerate technology transfer to address health care issues. During the second HCTP conference, in mid 1 995, a section of this meeting entitled: "Health Care Technology Assets of the Federal Government" addressed benefits of the technology transfer which should occur for maximizing already developed resources. Also a section entitled:"Transfer and Utilization of Government Technology Assets to the Private Sector", looked at both Health Care and non-Health Care related technologies since many areas such as Information Technologies (i.e. imaging, communications, archival I retrieval, systems integration, information display, multimedia, heterogeneous data bases, etc.) already exist and are part of our National Labs and/or other federal agencies, i.e. ARPA. These technologies although they are not labeled under "Health Care" programs they could provide enormous value to address technical needs. An additional issue deals with both the technical (hardware, software) and human expertise that resides within these labs and their possible role in creating cost effective solutions.

Cross, Roger T.; Price, Ronald F.

1991-12-01

In this paper we continue our search for a socially responsible science education by an examination of the trends in the Science, Technology and Society movement. These trends reflect differing ideological perspectives and result in courses which serve different ends. We identify two major flaws in the movement that inhibits the realization of a schooling in science dedicated to democracy. We propose skills necessary for citizens to participate in debate over issues surrounding the impact of science and technology on society and a teaching stategy to help develop them.

Strengthening and Fostering Science and Technology Programs in Latinamerica and the Caribbean

Fucugauchi, J. U.

2013-05-01

An overview and discussion of the status of research and education in Latinamerica and the Caribbean is used for developing a proposal for a research foundation or agency in the region and establishing initiatives for capacity building and promoting and strengthening scientific programs and cooperation. Scientific research increasingly requires global multi- and inter-disciplinary approaches and infrastructure. Developing countries face challenges resulting from small academic communities, limited economic resources, and pressing social and political issues. Science and education are not major priorities as compared with more pressing issues related to poverty, diseases, conflicts, drugs and famine. However, solving major problems require improved educational and research programs. International research collaboration, north-south and south-south, has an immense potential, but basic infrastructure and internal organization at national and regional levels are required. For the analysis we concentrate on current situation, size and characteristics of research community, education programs, facilities, economic support, and bilateral and multinational collaborations. Analysis also includes the São Paulo Research Foundation (FAPESP) and the Yucatan Science and Technology System (SIIDETEY). FAPESP is a highly successful public foundation started more than 50 years ago, dedicated to foster scientific and technological development in the State of São Paulo and which has had a major impact in Brazil. SIIDETEY is a more recent effort of the Yucatan Government, also dedicated to support research and technology innovation within the state. We then move to discussion on perspectives for future development and capacity building in regional and international contexts, including international collaboration programs. We propose to establish a Science Foundation for the Latinamerica and Caribbean and develop an agenda for strengthening scientific programs in the region.

2013-01-01

Collision avoidance technology has the capacity to facilitate safer mobility among older power mobility users with physical, sensory, and cognitive impairments, thus enabling independence for more users. Little is known about consumers' perceptions of collision avoidance. This article draws on interviews (29 users, 5 caregivers, and 10 prescribers) to examine views on design and utilization of this technology. Data analysis identified three themes: "useful situations or contexts," "technology design issues and real-life application," and "appropriateness of collision avoidance technology for a variety of users." Findings support ongoing development of collision avoidance for older adult users. The majority of participants supported the technology and felt that it might benefit current users and users with visual impairments, but might be unsuitable for people with significant cognitive impairments. Some participants voiced concerns regarding the risk for injury with power mobility use and some identified situations where collision avoidance might be beneficial (driving backward, avoiding dynamic obstacles, negotiating outdoor barriers, and learning power mobility use). Design issues include the need for context awareness, reliability, and user interface specifications. User desire to maintain driving autonomy supports development of collaboratively controlled systems. This research lays the groundwork for future development by illustrating consumer requirements for this technology.

Major transitions in human evolution.

Foley, Robert A; Martin, Lawrence; Mirazón Lahr, Marta; Stringer, Chris

2016-07-05

Evolutionary problems are often considered in terms of 'origins', and research in human evolution seen as a search for human origins. However, evolution, including human evolution, is a process of transitions from one state to another, and so questions are best put in terms of understanding the nature of those transitions. This paper discusses how the contributions to the themed issue 'Major transitions in human evolution' throw light on the pattern of change in hominin evolution. Four questions are addressed: (1) Is there a major divide between early (australopithecine) and later (Homo) evolution? (2) Does the pattern of change fit a model of short transformations, or gradual evolution? (3) Why is the role of Africa so prominent? (4) How are different aspects of adaptation-genes, phenotypes and behaviour-integrated across the transitions? The importance of developing technologies and approaches and the enduring role of fieldwork are emphasized.This article is part of the themed issue 'Major transitions in human evolution'. © 2016 The Author(s).

Implant ethics is defined here as the study of ethical aspects of the lasting introduction of technological devices into the human body. Whereas technological implants relieve us of some of the ethical problems connected with transplantation, other difficulties arise that are in need of careful analysis. A systematic approach to implant ethics is proposed. The major specific problems are identified as those concerning end of life issues (turning off devices), enhancement of human capabilities beyond normal levels, mental changes and personal identity, and cultural effects.

Baechler, M C; Gygi, K F; Hendrickson, P L

The Bonneville Power Administration (Bonneville) has identified 101 plants in the Pacific Northwest that account for 80% of the region's industrial electricity consumption. These plants offer a precise target for a conservation program. PNL determined that most of these 101 plants were represented by 11 major industries. We then reviewed 36 major conservation technologies used in these 11 industrial settings to determine their potential environmental impacts. Energy efficiency technologies designed for industrial use may result in direct or indirect environmental impacts. Effects may result from the production of the conservation measure technology, changes in the working environment due to differentmore » energy and material requirements, or changes to waste streams. Industry type, work-place conditions, worker training, and environmental conditions inside and outside the plant are all key variables that may affect environmental outcomes. To address these issues this report has three objectives: Describe potential conservation measures that Bonneville may employ in industrial programs and discuss potential primary impacts. Characterize industrial systems and processes where the measure may be employed and describe general environmental issues associated with each industry type. Review environmental permitting, licensing, and other regulatory actions required for industries and summarize the type of information available from these sources for further analysis.« less

The paper describes the authors' work in the area of health informatics (HI) education involving emerging health information technologies. A range of information technologies promise to modernize health care. Foremost among these are electronic health records (EHRs), which are expected to significantly improve and streamline health care practice. Major national and international efforts are currently underway to increase EHR adoption. However, there have been numerous issues affecting the widespread use of such information technology, ranging from a complex array of technical problems to social issues. This paper describes work in the integration of information technologies directly into the education and training of HI students at both the undergraduate and graduate level. This has included work in (a) the development of Web-based computer tools and platforms to allow students to have hands-on access to the latest technologies and (b) development of interdisciplinary educational models that can be used to guide integrating information technologies into HI education. The paper describes approaches that allow for remote hands-on access by HI students to a range of EHRs and related technology. To date, this work has been applied in HI education in a variety of ways. Several approaches for integration of this essential technology into HI education and training are discussed, along with future directions for the integration of EHR technology into improving and informing the education of future health and HI professionals.

Major transitions in information technology.

PubMed

Valverde, Sergi

2016-08-19

When looking at the history of technology, we can see that all inventions are not of equal importance. Only a few technologies have the potential to start a new branching series (specifically, by increasing diversity), have a lasting impact in human life and ultimately became turning points. Technological transitions correspond to times and places in the past when a large number of novel artefact forms or behaviours appeared together or in rapid succession. Why does that happen? Is technological change continuous and gradual or does it occur in sudden leaps and bounds? The evolution of information technology (IT) allows for a quantitative and theoretical approach to technological transitions. The value of information systems experiences sudden changes (i) when we learn how to use this technology, (ii) when we accumulate a large amount of information, and (iii) when communities of practice create and exchange free information. The coexistence between gradual improvements and discontinuous technological change is a consequence of the asymmetric relationship between complexity and hardware and software. Using a cultural evolution approach, we suggest that sudden changes in the organization of ITs depend on the high costs of maintaining and transmitting reliable information.This article is part of the themed issue 'The major synthetic evolutionary transitions'. © 2016 The Author(s).

Palinkas, C. M.

2014-12-01

Environmental and societal issues are often inherently linked, especially in coastal and estuarine environments, and science and social values must often be balanced in ecosystem management and decision-making. A new seminar course has been developed for the Marine Estuarine and Environmental Science (MEES) graduate program, an inter-institutional program within the University System of Maryland, to examine these issues. This 1-credit course, offered for the first time in Spring 2015, takes a complex systems perspective on major environmental and societal challenges to examine these linked issues in a variety of contexts. After a brief introduction to the emerging field of "geoethics," students develop a list of issues to examine throughout the seminar. Example topics could include fracking, offshore wind technology, dam removal, and iron fertilization, among others. A case-study approach is taken, with each class meeting focusing on one issue. For each case study, students are asked to 1) identify relevant scientific principles and major knowledge gaps, 2) predict potential outcomes, 3) identify stakeholders and likely viewpoints, and 4) construct communication plans to disseminate findings to these stakeholders. At the end of the semester, students give a brief presentation of the ethical aspects of their own research topics.

Advantages and Challenges of Radiative Liquid Lithium Divertor

NASA Astrophysics Data System (ADS)

Ono, Masayuki

2017-10-01

Steady-state fusion power plant designs present major divertor technology challenges, including high divertor heat flux both in steady-state and during transients. In addition to these concerns, there are the unresolved technology issues of long term dust accumulation and associated tritium inventory and safety issues. The application of lithium (Li) in NSTX resulted in improved H-mode confinement, H-mode power threshold reduction, and reduction in the divertor peak heat flux while maintaining essentially Li-free core plasma operation even during H-modes. These promising results in NSTX and related modeling calculations motivated the radiative liquid Li divertor (RLLD) concept and its variant, the active liquid Li divertor concept (ARLLD), taking advantage of the enhanced Li radiation in relatively poorly confined divertor plasmas. It has been suggested that radiation-based liquid lithium (LL) divertor concepts with a modest Li-loop could provide a possible solution for the outstanding fusion reactor technology issues such as divertor heat flux mitigation and real time dust removal, while potentially improving the reactor plasma performance. Laboratory tests are also planned to investigate the Li-T recover efficiency and other relevant research topics of the RLLD. This work supported by DoE Contract No. DE-AC02-09CH11466.

Towards a viable and just global nursing ethics.

PubMed

Crigger, Nancy J

2008-01-01

Globalization, an outgrowth of technology, while informing us about people throughout the world, also raises our awareness of the extreme economic and social disparities that exist among nations. As part of a global discipline, nurses are vitally interested in reducing and eliminating disparities so that better health is achieved for all people. Recent literature in nursing encourages our discipline to engage more actively with social justice issues. Justice in health care is a major commitment of nursing; thus questions in the larger sphere of globalization, justice and ethics, are our discipline's questions also. Global justice, or fairness, is not an issue for some groups or institutions, but a deeper human rights issue that is a responsibility for everyone. What can we do to help reduce or eliminate the social and economic disparities that are so evident? What kind of ethical milieu is needed to address the threat that globalization imposes on justice and fairness? This article enriches the conceptualization of globalization by investigating recent work by Schweiker and Twiss. In addition, I discuss five qualities or characteristics that will facilitate the development of a viable and just global ethic. A global ethic guides all people in their response to human rights and poverty. Technology and business, two major forces in globalization that are generally considered beneficial, are critiqued as barriers to social justice and the common good.

Ethical issues in the use of genetic information in the workplace: a review of recent developments.

PubMed

Geppert, Cynthia M A; Roberts, Laura Weiss

2005-09-01

In the wake of the Human Genome Project, the pace of genetic discovery has quickened. New genetic tests and other molecular technology have had immediate and wide relevance to American and European workers. These tests have the potential to provide improved workplace safety and protect workers' health, but they also carry the risk of genetic discrimination including loss of employment, promotion, insurance and health care. Ethical safeguards are necessary if the benefits are to outweigh the adverse consequences of genetics in the workplace. This review examines the major policy statements issued in Europe and the USA from 2000 to 2005 pertaining to genetic issues in occupational health. Recent findings stress that genetic testing can only be utilized with worker consent and that the workers should control access to genetic information. Such testing is only justified when the information is required to protect the safety of the worker or a third party. The progress of occupational genetic technology should not be permitted to shift the responsibility for a safe working environment from the employer to the employee. Genetic discrimination in all forms is neither supported scientifically nor warranted ethically. Increasingly, occupational physicians and clinicians treating workers will be faced with potentially stigmatizing genetic information and there is an urgent need for education and research to expand and implement the recommendations of major governmental and professional policy statements.

The developers as well as the users of remotely sensed data and geographic information system (GIS) techniques are associated with nearly all types of institutions in government, industry, and academia. Individuals in these various institutions often find the barriers to accepting remote sensing and GIS are not necessarily technical in nature, but can be attributed to the institutions themselves. Several major institutional issues that affect the technologies of remote sensing and GIS are data availability, data marketing and costs, equipment availability and costs, standards and practices, education and training, and organizational infrastructures. Not only are problems associated with these issues identified, but needs and opportunities also are discussed. -from Authors

The Emergence of Personalized Health Technology.

PubMed

Allen, Luke Nelson; Christie, Gillian Pepall

2016-05-10

Personalized health technology is a noisy new entrant to the health space, yet to make a significant impact on population health but seemingly teeming with potential. Devices including wearable fitness trackers and healthy-living apps are designed to help users quantify and improve their health behaviors. Although the ethical issues surrounding data privacy have received much attention, little is being said about the impact on socioeconomic health inequalities. Populations who stand to benefit the most from these technologies are unable to afford, access, or use them. This paper outlines the negative impact that these technologies will have on inequalities unless their user base can be radically extended to include vulnerable populations. Frugal innovation and public-private partnership are discussed as the major means for reaching this end.

Strategies for development of industrial wastewater reuse in Thailand.

PubMed

Visvanathan, C; Cippe, A

2001-01-01

Majority of the industrial activities in Thailand are concentrated around Bangkok Metropolitan Area. The ever increasing industrial activities have led to over exploitation of water resources and discharge of significant pollution load. Therefore, it is important to identify the wastewater reuse potentials and develop strategies for its promotion within the industrial sector. Although technological advances have made it possible to treat effluents for industrial re-use, in practice, the Thai industries do lack in implementation of such technologies. Promotion of cleaner production concepts and advanced new technologies such as membrane technologies could assist the industry for the implementation of wastewater reuse projects in Thailand. This paper discusses various technical, institutional and management related issues to promote industrial wastewater reuse, with few case studies.

An analysis of global problem issues in sixth-and seventh-grade textbooks

NASA Astrophysics Data System (ADS)

Hamm, Mary; Adams, Dennis

The study examines the extent to which the global issues of population growth, world hunger, air quality and atmosphere, and water resources were treated in sixth- and seventh-grade science textbooks. Ten textbooks were examined by five raters to determine the amount of content presented by different textbooks on global issues, the number of pages of content devoted to each issue, and the degree of depth in which issues were treated. Differences between grade levels were also explored. Of the 4,393 pages of content analyzed, less than 2 percent was devoted to these issues identified as the most serious human problems. No significant differences were found between textbook series. Significant differences were found in the number of pages of content presented on each issue. Most of the content fell into the categories of water resources, population growth, air quality, and atmosphere. The issue of war technology had the least amount of content. Distribution of content did not vary by grade level. Both levels addressed the issues of population growth, air quality, and water resources with a greater degree of depth than the issue of world hunger or war technology. The study concludes that the most widely used textbooks at the sixth- and seventh-grade levels avoid serious discussion of major global problems. And like the career indecision of a recent Miss America contestant, purchasers don't seem to be able to decide whether they want science textbooks to be a brain surgeon or a movie actress. Implications stemming from this dichotomy and its relationship to future science education curricular are also explored.

The purpose of this study is to identify the major challenges to coordination between emergency department (ED) teams and emergency medical services (EMS) teams. We conducted a series of focus groups involving both ED and EMS team members using a crisis scenario as the basis of the focus group discussion. We also collected organizational workflow data. We identified three major challenges to coordination between ED and EMS teams including ineffectiveness of current information and communication technologies, lack of common ground, and breakdowns in information flow. The three challenges highlight the importance of designing systems from socio-technical perspective. In particular, these inter-team coordination systems must support socio-technical issues such as awareness, context, and workflow between the two teams.

Heart failure patients' perceptions and use of technology to manage disease symptoms.

Technology use for symptom management is beneficial for both patients and physicians. Widespread acceptance of technology use in healthcare fuels continued development of technology with ever-increasing sophistication. Although acceptance of technology use in healthcare by medical professionals is evident, less is known about the perceptions, preferences, and use of technology by heart failure (HF) patients. This study explores patients' perceptions and current use of technology for managing HF symptoms (MHFS). A qualitative analysis of in-depth individual interviews using a constant comparative approach for emerging themes was conducted. Fifteen participants (mean age, 64.43 years) with HF were recruited from hospitals, cardiology clinics, and community groups. All study participants reported use of a home monitoring device, such as an ambulatory blood pressure device or bathroom scale. The majority of participants reported not accessing online resources for additional MHFS information. However, several participants stated their belief that technology would be useful for MHFS. Participants reported increased access to care, earlier indication of a worsening condition, increased knowledge, and greater convenience as potential benefits of technology use while managing HF symptoms. For most participants financial cost, access issues, satisfaction with current self-care routine, mistrust of technology, and reliance on routine management by their current healthcare provider precluded their use of technology for MHFS. Knowledge about HF patients' perceptions of technology use for self-care and better understanding of issues associated with technology access can aid in the development of effective health behavior interventions for individuals who are MHFS and may result in increased compliance, better outcomes, and lower healthcare costs.

The all electric aircraft considered in the present investigation is an aircraft which has digital flight crucial controls, electromechanical actuators, and electrical secondary power. There are no hydraulic or pneumatic systems. The characteristics of an all electric aircraft are related to reduced acquisition cost, reduced weight, reduced fuel consumption, increased reliability, reduced support equipment, simpler maintenance, an expanded flight envelope, and improved survivability. An additional benefit is the dramatically increased design flexibility and mission adaptability. However, the implementation of the all electric aircraft concept requires the resolution of a number of major technology issues. Issues in the digital flight controls area are related to achieving the required levels of safety and reliability in a cost effective manner. Other challenges which have to be met are concerned with electromechanical actuators, environmental control and ice protection systems, and engine technology.

Task toward a Realization of Commercial Tokamak Fusion Plants in 2050 -The Role of ITER and the Succeeding Developments- 4.Technology and Material Research in Fusion Power Plant Development

NASA Astrophysics Data System (ADS)

Akiba, Masato; Matsui, Hideki; Takatsu, Hideyuki; Konishi, Satoshi

Technical issues regarding the fusion power plant that are required to be developed in the period of ITER construction and operation, both with ITER and with other facilities that complement ITER are described in this section. Three major fields are considered to be important in fusion technology. Section 4.1 summarizes blanket study, and ITER Test Blanket Module (TBM) development that focuses its effort on the first generation power blanket to be installed in DEMO. ITER will be equipped with 6 TBMs which are developed under each party's fusion program. In Japan, the solid breeder using water as a coolant is the primary candidate, and He-cooled pebble bed is the alternative. Other liquid options such as LiPb, Li or molten salt are developed by other parties' initiatives. The Test Blanket Working Group (TBWG) is coordinating these efforts. Japanese universities are investigating advanced concepts and fundamental crosscutting technologies. Section 4.2 introduces material development and particularly, the international irradiation facility, IFMIF. Reduced activation ferritic/martensitic steels are identified as promising candidates for the structural material of the first generation fusion blanket, while and vanadium alloy and SiC/SiC composite are pursued as advanced options. The IFMIF is currently planning the next phase of joint activity, EVEDA (Engineering Validation and Engineering Design Activity) that encompasses construction. Material studies together with the ITER TBM will provide essential technical information for development of the fusion power plant. Other technical issues to be addressed regarding the first generation fusion power plant are summarized in section 4.3. Development of components for ITER made remarkable progress for the major essential technology also necessary for future fusion plants, however many still need further improvements toward power plant. Such areas includes; the divertor, plasma heating/current drive, magnets, tritium, and remote handling. There remain many other technical issues for power plant which require integrated efforts.

Lessons learned studying design issues for lunar and Mars settlements

Litton, C. E.

1997-01-01

In a study of lunar and Mars settlement concepts, an analysis was made of fundamental design assumptions in five technical areas against a model list of occupational and environmental health concerns. The technical areas included the proposed science projects to be supported, habitat and construction issues, closed ecosystem issues, the "MMM" issues (mining, material processing, and manufacturing), and the human elements of physiology, behavior, and mission approach. Four major lessons were learned. First it is possible to relate public health concerns to complex technological development in a proactive design mode, which has the potential for long-term cost savings. Second, it became very apparent that prior to committing any nation or international group to spending the billions to start and complete a lunar settlement, over the next century, that a significantly different approach must be taken from those previously proposed, to solve the closed ecosystem and "MMM" problems. Third, it also appears that the health concerns and technology issues to be addressed for human exploration into space are fundamentally those to be solved for human habitation of the Earth (as a closed ecosystem) in the 21st century. Finally, it is proposed that ecosystem design modeling must develop new tools, based on probabilistic models as a step up from closed circuit models.

Ethical issues in molecular medicine of relevance to surgeons

PubMed Central

Bernstein, Mark; Bampoe, Joseph; Daar, Abdallah S.

2004-01-01

The technology associated with the care of surgical patients and the level of sophistication of biomedical research accompanying it are evolving at a rapid pace. Both new and old bioethical issues are assuming increasing levels of prominence and importance, particularly in this age of molecular medicine. The authors explore bioethical issues pertinent and relevant to surgeons. Four specific areas that are exemplary by presenting both major scientific and ethical challenges are briefly addressed: privacy of information, stem cells, gene therapy, and conflict of interest in biomedical research. All of these can be generalized to all surgeons. As bioethical issues today play a greater role in surgical practice than they did even a decade ago, it is hoped that this brief review on ethical issues in molecular medicine will help stimulate present and future generations of surgeons in thinking about the ethical dimensions of their work.

Some ethical issues in technology transfer and applications

NASA Astrophysics Data System (ADS)

Shine, Kenneth I.

1995-10-01

Health care systems all around the world are struggling to provide care in an era of limited resources. In an article entitled, 'Straight Talk About Rationing,' Arthur Kaplan reviews the work of the Swedish Commission designed to prioritize health care for that country. The commission identified three core principles that they felt should underlie decisions about priorities for health care. Those principles were (1) all human beings are equally valuable; (2) society must pay special attention to the needs of the weakest and most vulnerable; and (3) all other things being equal, cost efficiency in gaining the greatest return for the amount of money spent must prevail. These are three extremely useful principles which can be helpful to us as we consider many of the issues confronted in this country about the allocation of resources for health. I would like to consider three major issues. The first issue is the current evolving nature of health care and the ethical dilemmas that exist in the present system. In balancing increased access to care with decreasing cost, particularly in managed care, all of us are concerned about ethical issues. I would like to emphasize that the current system -- the system that we have lived with and is changing -- has inherent in it a series of ethical dilemmas. Secondly, I would like to consider issues related to productivity and its measurement in relation to technology. This relates to the third item in the Swedish Commission, which is the principle that we ought to spend money in the most cost-efficient way. Finally, I would like to discuss the dilemma of decision making about health and how that impacts upon the ethics of health care in the application of technology.

Nuclear Technology, Global Warming, and the Politicization of Science

NASA Astrophysics Data System (ADS)

Weart, Spencer

2016-03-01

Since the mid 20th century physical scientists have engaged in two fierce public debates on issues that posed existential risks to modern society: nuclear weapons and global warming. The two overlapped with a third major debate over the deployment of nuclear power reactors. Each controversy included technical disagreements raised by a minority among the scientists themselves. Despite efforts to deal with the issues objectively, the scientists became entangled in left vs. right political polarization. All these debates, but particularly the one over climate change, resulted in a deterioration of public faith in the objectivity and integrity of scientists.

Authoritative knowledge, the technological imperative and women's responses to prenatal diagnostic technologies.

PubMed

McCoyd, Judith L M

2010-12-01

Theories about authoritative knowledge (AK) and the technological imperative have received varying levels of interest in anthropological, feminist and science and technology studies. Although the anthropological literature abounds with empirical considerations of authoritative knowledge, few have considered both theories through an empirical, inductive lens. Data extracted from an earlier study of 30 women's responses to termination for fetal anomaly are reanalyzed to consider the women's views of, and responses to, prenatal diagnostic technologies (PNDTs). Findings indicate that a small minority embrace the societal portrayal of technology as univalently positive, while the majority have nuanced and ambivalent responses to the use of PNDTs. Further, the interface of authoritative knowledge and the technological imperative suggests that AK derives not only from medical provider status and technology use, but also from the adequacy and trustworthiness of the information. The issue of timing and uncertainty of the information also are interrogated for their impact on women's lives and what that can illuminate about the theories of AK and the technological imperative.

Promisel, Nathan E.

1985-12-01

Recognizing the pervasive importance of materials science and engineering (MSE) to practically every facet of man’s life, this lecture takes a broad view of the origin and technical trends and achievements in MSE, briefly reviewing its history and relationship to society over many millennia, to the present day, with specific examples. Major emphasis, however, is placed on modern MSE as related to current national issues, using as illustrations of the latter natural resources, industry and the economy, research and development, education, and technology transfer. The discussion of these areas leads to consideration of the role of the Federal Government and the importance of and need for a coherent national policy to deal with critical issues, many of which are listed herein. Some important steps by the Government fostering high level coordination as well as cooperation among government, industry, and academe are cited. Having thus illustrated the pervasive and vital impact of MSE on society, and its current esteemed recognition and position of influence, the lecture concludes that in this period of global change — social, economic, and technological — there is a challenge to MSE to respond beneficially to societal needs more than ever before. The opportunity and mechanisms now exist. Greater participation in the public and political arenas, with mutual education, is indicated.

Cultivating Diversity and Competency in STEM: Challenges and Remedies for Removing Virtual Barriers to Constructing Diverse Higher Education Communities of Success.

Whittaker, Joseph A; Montgomery, Beronda L

2012-01-01

The need to increase the number of college graduates in Science, Technology, Engineering, and Mathematics (STEM) disciplines is a national issue. As the demographics of the United States' population grow increasingly more diverse, the recognition that students of color are disproportionately under-represented among those individuals successful at completing STEM degrees requires exigent and sustained intervention. Although a range of efforts and funding have been committed to increasing the success of under-represented minority (URM) students at primarily white, or majority, institutions, widespread progress has been slow. Simultaneously, Historically Black Colleges and Universities and Minority Serving Institutions have demonstrated disproportionate successes in graduating URM students with STEM degrees and those that proceed to completing graduate-level degrees in the sciences. The differential successes of particular institutions with promoting the achievement of diverse individuals in obtaining academic STEM degrees suggest that with committed and strategic leadership, advancements in creating academic communities that promote the success of a diverse range of students in STEM can be achieved in part through assessing and mitigating environmental barriers that impede success at majority institutions. In this paper, we address issues related to the engagement of URM students in majority settings and describe some efforts that have shown success for promoting diversity in STEM and highlight continuing issues and factors associated with cultivating diversity in academic STEM disciplines at majority institutions. Recommended efforts include addressing academic assistance, professional and cultural socialization issues and institutional environmental factors that are associated with success or lack thereof for URMs in STEM.

Background. While assisted reproductive technology (ART), including in vitro fertilization has given hope to millions of couples suffering from infertility, it has also introduced countless ethical, legal, and social challenges. The objective of this paper is to identify the aspects of ART that are most relevant to present-day society and discuss the multiple ethical, legal, and social challenges inherent to this technology. Scope of Review. This paper evaluates some of the most visible and challenging topics in the field of ART and outlines the ethical, legal, and social challenges they introduce. Major Conclusions. ART has resulted in a tectonic shift in the way physicians and the general population perceive infertility and ethics. In the coming years, advancing technology is likely to exacerbate ethical, legal, and social concerns associated with ART. ART is directly challenging society to reevaluate the way in which human life, social justice and equality, and claims to genetic offspring are viewed. Furthermore, these issues will force legal systems to modify existing laws to accommodate the unique challenges created by ART. Society has a responsibility to ensure that the advances achieved through ART are implemented in a socially responsible manner. PMID:22272208

Animal-cell culture media: History, characteristics, and current issues.

Yao, Tatsuma; Asayama, Yuta

2017-04-01

Cell culture technology has spread prolifically within a century, a variety of culture media has been designed. This review goes through the history, characteristics and current issues of animal-cell culture media. A literature search was performed on PubMed and Google Scholar between 1880 and May 2016 using appropriate keywords. At the dawn of cell culture technology, the major components of media were naturally derived products such as serum. The field then gradually shifted to the use of chemical-based synthetic media because naturally derived ingredients have their disadvantages such as large batch-to-batch variation. Today, industrially important cells can be cultured in synthetic media. Nevertheless, the combinations and concentrations of the components in these media remain to be optimized. In addition, serum-containing media are still in general use in the field of basic research. In the fields of assisted reproductive technologies and regenerative medicine, some of the medium components are naturally derived in nearly all instances. Further improvements of culture media are desirable, which will certainly contribute to a reduction in the experimental variation, enhance productivity among biopharmaceuticals, improve treatment outcomes of assisted reproductive technologies, and facilitate implementation and popularization of regenerative medicine.

1995-01-01

Power-By-Wire (PBW) is a program involving the replacement of hydraulic and pneumatic systems currently used in aircraft with an all-electric secondary power system. One of the largest loads of the all-electric secondary power system will be the motor loads which include pumps, compressors and Electrical Actuators (EA's). Issues of improved reliability, reduced maintenance and efficiency, among other advantages, are the motivation for replacing the existing aircraft actuators with electrical actuators. An EA system contains four major components. These are the motor, the power electronic converters, the actuator and the control system, including the sensors. This paper is a comparative literature review in motor drive technologies, with a focus on the trends and tradeoffs involved in the selection of a particular motor drive technology. The reported research comprises three motor drive technologies. These are the induction motor (IM), the brushless dc motor (BLDCM) and the switched reluctance motor (SRM). Each of the three drives has the potential for application in the PBW program. Many issues remain to be investigated and compared between the three motor drives, using actual mechanical loads expected in the PBW program.

After seven papers discussing specific examples of ecological sanitation projects, the workshop considered the background, motivation and feasibility of this technology. It was agreed that ecological sanitation could help tackle water scarcity, health protection and, by recycling water and nutrients into agriculture, food scarcity. Dense cities are probably unsuitable for its implementation, but rural, town and peri-urban areas are promising. Key issues that remains are: the microbiological and chemical risks associated with the technology; the need for major information, education and support programmes; effective linking to reuse schemes; tailoring systems to meet local physical, socio-economic and cultural circumstances.

The following conclusions have been developed relative to propulsion system technology adequacy for efficient development and operation of recoverable and expendable launch vehicles (RLV and ELV) and the benefits which the integrated propulsion technology demonstrator will provide for enhancing technology: (1) Technology improvements relative to propulsion system design and operation can reduce program cost. Many features or improvement needs to enhance operability, reduce cost, and improve payload are identified. (2) The Integrated Propulsion Technology Demonstrator (IPTD) Program provides a means of resolving the majority of issues associated with improvement needs. (3) The IPTD will evaluate complex integration of vehicle and facility functions in fluid management and propulsion control systems, and provides an environment for validating improved mechanical and electrical components. (4) The IPTD provides a mechanism for investigating operational issues focusing on reducing manpower and time to perform various functions at the launch site. These efforts include model development, collection of data to validate subject models, and ultimate development of complex time line models. (5) The IPTD provides an engine test bed for tri/bi-propellant engine development firings which is representative of the actual vehicle environment. (6) The IPTD provides for only a limited multiengine configuration integration environment for RLV. Multiengine efforts may be simulated for a number of subsystems and a number of subsystems are relatively independent of the multiengine influences.

Power Mobility with Collision Avoidance for Older Adults: User, Caregiver and Prescriber Perspectives

2017-01-01

Collision avoidance technology has the capacity to facilitate safer mobility among older power mobility users with physical, sensory and cognitive impairments, thus enabling independence for more potential users. However, little is known about consumers’ perceptions of collision avoidance. This article draws on interviews with 29 users, five caregivers, and 10 prescribers to examine views on the design and utilization of this technology. Data analysis identified three themes: “useful situations or contexts”, “technology design issues and real life application”, and “appropriateness of collision avoidance technology for a variety of users”. Findings support the ongoing development of collision avoidance for older adult users. The majority of participants were supportive of the technology, and felt that it might benefit current power mobility users and users with visual impairments, but might be unsuitable for people with significant cognitive impairments. Some participants voiced concerns regarding the risk for injury with power mobility use and some identified situations where collision avoidance might be beneficial (driving backwards, avoiding dynamic obstacles, negotiating outdoor barriers, and learning power mobility use). Design issues include the need for context awareness, reliability, and user interface specifications. Furthermore, user desire to maintain driving autonomy indicates the need to develop collaboratively-controlled systems. This research lays the groundwork for future development by identifying and illustrating consumer needs for this technology. PMID:24458968

Since pico-projectors were starting to become the next electronic "must-have" gadget, the experts were discussing which light-source technology seems to be the best for the existing three major projection approaches for the optical scanning module such as digital light processing, liquid crystal on silica and laser beam steering. Both so-far used light source technologies have distinct advantages and disadvantages. Though laser-based pico-projectors are focus-free and deliver a wider color gamut, their major disadvantages are speckle noise, cost and safety issues. In contrast, projectors based on cheaper Light Emitting Diodes (LEDs) as light source are criticized for a lack of brightness and for having limited focus. Superluminescent Light Emitting Diodes (SLEDs) are temporally incoherent and spatially coherent light sources merging in one technology the advantages of both Laser Diodes (LDs) and LEDs. With almost no visible speckle noise, focus-free operation and potentially the same color gamut than LDs, SLEDs could potentially answer the question which light source to use in future projector applications. In this quest for the best light source, we realized visible SLEDs emitting both in the red and blue spectral region. While the technology required for the realization of red emitters is already well established, III-nitride compounds required for blue emission have experienced a major development only in relatively recent times and the technology is still under development. The present paper is a review of the status of development reached for the blue superluminescent diodes based on the GaN material system.

Microbial technology with major potentials for the urgent environmental needs of the next decades.

2017-09-01

Several needs in the context of the water-energy-food nexus will become more prominent in the next decades. It is crucial to delineate these challenges and to find opportunities for innovative microbial technologies in the framework of sustainability and climate change. Here, we focus on four key issues, that is the imbalance in the nitrogen cycle, the diffuse emission of methane, the necessity for carbon capture and the deterioration of freshwater reserves. We suggest a set of microbial technologies to deal with each of these issues, such as (i) the production of microbial protein as food and feed, (ii) the control of methanogenic archaea and better use of methanotrophic consortia, (iii) the avoidance of nitrification and (iv) the upgrading of CO 2 to microbial bioproducts. The central message is that instead of using crude methods to exploit microorganisms for degradations, the potentials of the microbiomes should be used to create processes and products that fit the demands of the cyclic market economy. © 2017 The Authors.

2013-02-01

During recent years, major advances have been made in neuroscience, i.e., asynchronous release, three-dimensional structural data sets, saliency maps, magnesium in brain research, and new functional roles of long non-coding RNAs. Especially, the development of optogenetic technology provides access to important information about relevant neural circuits by allowing the activation of specific neurons in awake mammals and directly observing the resulting behavior. The Grand Research Plan for Neural Circuits of Emotion and Memory was launched by the National Natural Science Foundation of China. It takes emotion and memory as its main objects, making the best use of cutting-edge technologies from medical science, life science and information science. In this paper, we outline the current status of neural circuit studies in China and the technologies and methodologies being applied, as well as studies related to the impairments of emotion and memory. In this phase, we are making efforts to repair the current deficiencies by making adjustments, mainly involving four aspects of core scientific issues to investigate these circuits at multiple levels. Five research directions have been taken to solve important scientific problems while the Grand Research Plan is implemented. Future research into this area will be multimodal, incorporating a range of methods and sciences into each project. Addressing these issues will ensure a bright future, major discoveries, and a higher level of treatment for all affected by debilitating brain illnesses.

Telemedicine in neurosurgical emergency: Indian perspective

PubMed Central

Sinha, Virendra Deo; Tiwari, Rahul Nath; Kataria, Rashim

2012-01-01

Telemedicine is rapidly developing telecommunication technology to provide medical information and services. The importance of telemedicine for neurosurgical emergencies was established with the fact that majority of the neurosurgical specialists are practicing in urban settings and in most of the rural areas, neurosurgical care is far off or non-existing. Countries with inadequate health care must incorporate telemedicine in their health care system. Telemedicine offers real benefits in a country as vast as India, where the majority of the population lives in remote areas with no access to even the most basic healthcare. Issues pertaining security, privacy, maintaining standards, and legal aspects are relevant. A recommended set of standards and guidelines for telemedicine needs to be set in place and constantly refined to promote the integrated growth of telemedicine in the country. The paper discusses various issues, shortcomings, and utility of telemedicine in India. PMID:22870155

2003-05-01

The dialog among investigators in academia, industry, NIH, and the FDA has grown in recent years on topics of historic interest to attendees of these SPIE sub-conferences on Image Perception, Observer Performance, and Technology Assessment. Several of the most visible issues in this regard have been the emergence of digital mammography and modalities for computer-assisted detection and diagnosis in breast and lung imaging. These issues appear to be only the "tip of the iceberg" foreshadowing a number of emerging advances in imaging technology. So it is timely to make some general remarks looking back and looking ahead at the landscape (or seascape). The advances have been facilitated and documented in several forums. The major role of the SPIE Medical Imaging Conferences i well-known to all of us. Many of us were also present at the Medical Image Perception Society and co-sponsored by CDRH and NCI in September of 2001 at Airlie House, VA. The workshops and discussions held at that conference addressed some critical contemporary issues related to how society - and in particular industry and FDA - approach the general assessment problem. A great deal of inspiration for these discussions was also drawn from several workshops in recent years sponsored by the Biomedical Imaging Program of the National Cancer Institute on these issues, in particular the problem of "The Moving Target" of imaging technology. Another critical phenomenon deserving our attention is the fact that the Fourth National Forum on Biomedical Imaging in Oncology was recently held in Bethesda, MD., February 6-7, 2003. These forums are presented by the National Cancer Institute (NCI), the Food and Drug Administration (FDA), the Centers for Medicare and Medicaid Services (CMS), and the National Electrical Manufacturers Association (NEMA). They are sponsored by the National Institutes of Health/Foundation for Advanced Education in the Sciences (NIH/FAES). These forums led to the development of the NCI"s Interagency Council on Biomedical Imaging in Oncology (ICBIO) about two and a half years ago. The purpose of the ICBIO is to assist developers of new imaging technologies for cancer screening and diagnosis to find a coherent way to interface with government agencies with responsibilities in these areas. A recent product of these activities was an overview paper written by the present authors and published this year in the Journal Academic Radiology (2). The paper includes a summary of some of the major developments in assessment methodology in recent years and includes several case studies from the public forum of the FDA"s Center for Devices & Radiological Health (CDRH). We will include a brief sketch of some of the key issues of that paper in this review.

PM₂.₅ opened a door to public participation addressing environmental challenges in China.

PubMed

Huang, Ganlin

2015-02-01

China has long been regarded as a centralized society where the public has little influence on decision-making. Such a top-down management scheme is perceived as a major obstacle to address complicated environment issues. The recent public campaign in China to urge creation of a nationwide PM₂.₅ monitoring network and mitigation plan provides an unprecedented case of how the public participated and influenced policy-making in a centralized society. This paper reviews key incidents in the campaign chronologically. Here we identify information technology, public awareness of air quality's health impacts and the fact air quality affects everyone as public goods as the major factors promoting public participation. This case demonstrates that public participation can happen in a centralized, top-down society such as China. Continued environmental deterioration may stimulate similar campaigns for other issues. We anticipate this essay to be a starting point for more studies on how environmental issues stimulate incremental social change by making people involved in decision-making process, especially in societies where they are rarely able to do so.

The development of high-tech industry has been prosperous around the world in past decades, while technology and finance have already become the most significant issues in the information era. While high-tech firms are a major force behind a country's economic development, it requires a lot of money for the development process, as well as the financing difficulties for its potential problems, thus, how to evaluate and establish appropriate technology and financial services platforms innovation strategy has become one of the most critical and difficult issues. Moreover, how the chosen intertwined financial environment can be optimized in order that high-tech firms financing problems can be decided has seldom been addressed. Thus, this research aims to establish a technology and financial services platform innovation strategy improvement model, as based on the hybrid MADM model, which addresses the main causal factors and amended priorities in order to strengthen ongoing planning. A DEMATEL technique, as based on Analytic Network Process, as well as modified VIKOR, will be proposed for selecting and re-configuring the aspired technology and financial services platform. An empirical study, as based on China's technology and financial services platform innovation strategy, will be provided for verifying the effectiveness of this proposed methodology. Based on expert interviews, technology and financial services platforms innovation strategy improvement should be made in the following order: credit guarantee platform ( C )_credit rating platform ( B )_investment and finance platform ( A ).

The use of psychopharmaceuticals as an enhancement technology has been the focus of attention in the bioethics literature. However, there has been little examination of the challenges that this practice creates for religious traditions that place importance on questions of being, authenticity, and identity. We asked expert commentators from six major world religions to consider the issues raised by psychopharmaceuticals as an enhancement technology. These commentaries reveal that in assessing the appropriate place of medical therapies, religious traditions, like secular perspectives, rely upon ideas about health and disease and about normal human behavior. But unlike secular perspectives, faith traditions explicitly concern themselves with ways in which medicine should or should not be used to live a "good life".

A number of regulatory and institutional impediments to the development of geothermal energy exist. None of these seem likely to prevent the development of this energy source, but in the aggregate they will pace its growth as certainly as the technological issues. The issues are associated with the encouragement of exploration and development, assuring a market for geothermal steam or hot water, and accomplishing the required research and development in a timely manner. The development of geothermal energy in the United States at a high level is apt to cause both favorable and unfavorable, though manageable, impacts in eight major areas, which are discussed.

Issues facing the Australian Health Technology Assessment Review of medical technology funding.

PubMed

O'Malley, Susanne P

2010-07-05

The Australian Health Technology Assessment Review has the potential to have a major effect on the availability of new medical technology and the listing of associated medical procedures on the Medicare Benefits Schedule. Despite this, only about 15% of submissions to the Review came from "medical associations". Pharmaceutical and medical technologies are inherently different, and there are a number of difficulties associated with evaluating medical technology using the same process and evidence levels as those used for pharmaceuticals. The current sequential and lengthy processing of new medical technology and procedures is delaying access to beneficial medical technology and could be substantially reduced. There is currently no effective funding process for medical technology classified as capital equipment or consumables and disposables. This has created a perverse incentive in favour of using funded implantable prostheses based on access to funding rather than superior clinical effectiveness. The existing horizon scanning process could be better used to not only identify all potentially cost-effective new and emerging medical technology and procedures as early as possible, but also to identify gaps in the evidence.

Bot, Adrian

2011-01-01

As the immune system essentially evolved to fight off or keep at bay life-threatening infectious agents rather than cancer, the question remains as to how to best redeploy it for the treatment of a broader range of diseases. This is reflected by an unprecedented diversification of platform technologies in development, facilitated by rapid progress in biotechnology. In this issue, we host several contributions outlining major efforts in developing novel immune interventions spanning antigen-specific vaccination, non-antigen-targeted immune intervention, genetically engineered lymphocytes, and ultraspecific antigen-targeted ligands. In addition, the journal is hosting in this issue, two reviews discussing the complex matter and dynamic balance between immunity and viral infections, as the concept of fine modulation of that balance still carries the promise of yielding novel therapies.

The Relationship of Discipline Background to Upper Secondary Students' Argumentation on Socioscientific Issues

Christenson, Nina; Chang Rundgren, Shu-Nu; Zeidler, Dana L.

2014-08-01

In the present STEM (Science, Technology, Engineering, and Mathematics)-driven society, socioscientific issues (SSI) have become a focus globally and SSI research has grown into an important area of study in science education. Since students attending the social and science programs have a different focus in their studies and research has shown that students attending a science program are less familiar with argumentation practice, we make a comparison of the supporting reasons social science and science majors use in arguing different SSI with the goal to provide important information for pedagogical decisions about curriculum and instruction. As an analytical framework, a model termed SEE-SEP covering three aspects (of knowledge, value, and experiences) and six subject areas (of sociology/culture, economy, environment/ecology, science, ethics/morality, and policy) was adopted to analyze students' justifications. A total of 208 upper secondary students (105 social science majors and 103 science majors) from Sweden were invited to justify and expound their arguments on four SSI including global warming, genetically modified organisms (GMO), nuclear power, and consumer consumption. The results showed that the social science majors generated more justifications than the science majors, the aspect of value was used most in students' argumentation regardless of students' discipline background, and justifications from the subject area of science were most often presented in nuclear power and GMO issues. We conclude by arguing that engaging teachers from different subjects to cooperate when teaching argumentation on SSI could be of great value and provide students from both social science and science programs the best possible conditions in which to develop argumentation skills.

NASA, Marshall Space Flight Center (MSFC) is developing a Urine Processor Assembly (UPA) for the International Space Station (ISS). The UPA uses Vapor Compression Distillation (VCD) technology to reclaim water from pre-treated urine. This water is further processed by the Water Processor Assembly (WPA) to potable quality standards for use on the ISS. NASA has developed this technology over the last 25-30 years. Over this history, many technical issues were solved with thousands of hours of ground testing that demonstrate the ability of the UPA technology to reclaim water from urine. In recent years, NASA MSFC has been responsible for taking the UPA technology to "flight design" maturity. This paper will give a brief overview of the UPA design and a status of the major design and development efforts completed recently to mature the UPA to a flight level.

Safe laser application requires more than laser safety

Frevel, A.; Steffensen, B.; Vassie, L.

1995-02-01

An overview is presented concerning aspects of laser safety in European industrial laser use. Surveys indicate that there is a large variation in the safety strategies amongst industrial laser users. Some key problem areas are highlighted. Emission of hazardous substances is a major problem for users of laser material processing systems where the majority of the particulate is of a sub-micrometre size, presenting a respiratory hazard. Studies show that in many cases emissions are not frequently monitored in factories and uncertainty exists over the hazards. Operators of laser machines do not receive adequate job training or safety training. The problem is compounded by a plethora of regulations and standards which are difficult to interpret and implement, and inspectors who are not conversant with the technology or the issues. A case is demonstrated for a more integrated approach to laser safety, taking into account the development of laser applications, organizational and personnel development, in addition to environmental and occupational health and safety aspects. It is necessary to achieve a harmonization between these elements in any organization involved in laser technology. This might be achieved through establishing technology transfer centres in laser technology.

Unsustainable harvesting of natural fish stocks is driving an ever growing marine aquaculture industry. Part of the aquaculture support industry is net suppliers who provide producers with nets used in confining fish while they are grown to market size. Biofouling must be addressed in marine environments to ensure maximum product growth by maintaining water flow and waste removal through the nets. Biofouling is managed with copper and organic biocide based net coatings. The aquaculture industry provides a case study for business issues related to entry of improved fouling management technology into the marketplace. Several major hurdles hinder entry of improved novel technologies into the market. The first hurdle is due to the structure of business relationships. Net suppliers can actually cut their business profits dramatically by introducing improved technologies. A second major hurdle is financial costs of registration and demonstration of efficacy and quality product with a new technology. Costs of registration are prohibitive if only the net coatings market is involved. Demonstration of quality product requires collaboration and a team approach between formulators, net suppliers and farmers. An alternative solution is a vertically integrated business model in which the support business and product production business are part of the same company.

Many obstacles need to be overcome if digital and electronic technologies are to be fully integrated in the operation of dental clinics in some countries. These obstacles may be physical, technical, or psychosocial barriers in the form of perceptions and attitudes related to software incompatibilities, patient privacy, and interference with the patient-practitioner relationship. The objectives of the study are to assess the perceptions of Indian dental students of one school toward the usefulness of digital technologies in improving dental practice; their willingness to use digital and electronic technologies; the perceived obstacles to the use of digital and electronic technologies in dental care setups; and their attitudes toward Internet privacy issues. The study population consisted of 186 final year undergraduate dental students from the A. B. Shetty Memorial institute of Dental Sciences, Rajiv Gandhi University of Health Sciences, Mangalore, India. Survey data were analyzed descriptively . Most students indicated that information technology enhances patient satisfaction, the quality of dental record, diagnosis, treatment planning, and doctor-doctor communication. Cost of equipment and need for technical training were regarded as major obstacles by substantial proportions of respondents. Most dental students at our school feel that the information technology will support their decision making in diagnoses and devising effective treatment plans, which in turn increase patient satisfaction and quality of care. Students also perceived that lack of technical knowledge and the high cost of implementation are major barriers to developing information technology in India.

Today's global energy crisis requires a multifaceted solution. Bioenergy is an important part of the solution. The microbial fuel cell (MFC) technology stands out as an attractive potential technology in bioenergy. MFCs can convert energy stored in organic matter directly into bioelectricity. MFCs can also be operated in the electrolysis mode as microbial electrolysis cells to produce bioproducts such as hydrogen and ethanol. Various wastewaters containing low-grade organic carbons that are otherwise unutilized can be used as feed streams for MFCs. Despite major advances in the past decade, further improvements in MFC power output and cost reduction are needed for MFCs to be practical. This paper analysed MFC operating principles using bioenergetics and bioelectrochemistry. Several major issues were explored to improve the MFC performance. An emphasis was placed on the use of catalytic materials for MFC electrodes. Recent advances in the production of various biomaterials using MFCs were also investigated.

The 'Magic Light': A Discussion on Laser Ethics.

PubMed

Stylianou, Andreas; Talias, Michael A

2015-08-01

Innovations in technology and science form novel fields that, although beneficial, introduce new bio-ethical issues. In their short history, lasers have greatly influenced our everyday lives, especially in medicine. This paper focuses particularly on medical and para-medical laser ethics and their origins, and presents the complex relationships within laser ethics through a three-dimensional matrix model. The term 'laser' and the myth of the 'magic light' can be identified as landmarks for laser related ethical issues. These ethical issues are divided into five major groups: (1) media, marketing, and advertising; (2) economic outcomes; (3) user training; (4) the user-patient/client relationship; and (5) other issues. In addition, issues arising from two of the most common applications of lasers, laser eye surgery and laser tattoo removal, are discussed. The aim of this paper is to demonstrate that the use of medical and para-medical lasers has so greatly influenced our lives that the scientific community must initiate an earnest discussion of medical laser ethics.

The purpose of this study is to examine the role of information and communication technology (ICT) in enhancing community outreach, academic and research collaboration, and education and support services (IT-CARES) in an academic setting. A survey was deployed to assess the ICT needs in an academic setting. The survey was developed using the Delphi methodology. Questionnaire development was initiated by asking key stakeholders involved in community outreach, academic, research, education, and support to provide feedback on current ICT issues and future recommendations for relevant ICT tools that would be beneficial to them in their job, and to capture current ICT issues. Participants were asked to rate the level of importance of each ICT question on five-point Likert scales. The survey was sent to 359 participants, including faculty, staff, and students. The total number of respondents was 96, for a 27 percent response rate. The majority of the participants (54.1 percent, n = 46) placed a high importance on learning the available research capabilities of the college. The majority of the participants placed moderate (43.5 percent, n = 37) to high importance (40 percent, n = 34) on having an intranet that could support collaborative grant writing. A majority of the participants attributed high importance to learning to interact with the online learning management system Blackboard. A majority of the participants agreed that social media should being more actively utilized for diverse activities for academic and research purposes. The study helped to identify the current needs and challenges faced by professionals and students when interacting with ICT. More research is needed in order to effectively integrate the use of ICT in the field of higher education, especially related to the modern global public health context.

The construction industry in Sabah is one of the major roles for development of social, economic infrastructures and buildings in generating wealth to the state besides the tourism sector. The increasing number of construction projects particularly in the rapid developing city of Kota Kinabalu, green technology as a whole is becoming more significant as it helps to develop effective solutions to encounter global environmental issues. The objective of the research is to identify the awareness and implementation of green technology in construction industry in Kota Kinabalu, Sabah. The methodology of the research is through distributing the questionnaire to the contractors, developers, consultants, architects and state government agencies to the area in Kota Kinabalu only. The questionnaires had been analysed to find out the mean value. 100 questionnaires distributed to the respondents but merely 85 questionnaires collected have been analysed. Based on the findings, 83.5% organisations were aware with the concept of green technology in construction project. In terms of the implementation only 64.7% had been implemented in their organizations. More than 50% from the major players such as contractors, consultants, developers, architects and state government agencies were aware based on six green technology concepts in their organizations. As a conclusion, the awareness towards green policy concept in construction industry is very satisfied. Meanwhile, in terms of implementation need to be increased the number of organizations to be involved in green technology in construction industry.

Preparing for future human exploration of the Moon and beyond is an interdisciplinary exercise, requiring new technologies and the pooling of knowledge and expertise from many scientific areas. The European Space Agency is working to develop a Lunar Lander, as a precursor to future human exploration activities. The mission will demonstrate new technologies and perform important preparatory investigations. In the biological sciences the two major areas requiring investigation in advance of human exploration are radiation and its effects on human physiology and the potential toxicity of lunar dust. This paper summarises the issues associated with these areas and the investigations planned for the Lunar Lander to address them.

Generational affinities and discourses of difference: a case study of highly skilled information technology workers.

Sociologists theorizing the concept of 'generation' have traditionally looked to birth cohorts sharing major social upheavals such as war or decolonization to explain issues of generational solidarity and identity affiliation. More recently, theorists have drawn attention to the cultural elements where generations are thought to be formed through affinities with music or other types of popular culture during the 'coming of age' stage of life. In this paper, we ask whether developments in computer technology, which have both productive and cultural components, provide a basis for generational formation and identity and whether generational discourse is invoked to create cultures of difference in the workplace. Qualitative data from a sample of Information Technology workers show that these professionals mobilize 'generational' discourse and draw upon notions of 'generational affinity' with computing technology (e.g. the fact that people of different ages were immersed to varying degrees in different computing technologies) in explaining the youthful profile of IT workers and employees' differing levels of technological expertise.

This report is the first of four volumes that identify and assess the environmental, health, and safety issues involved in using sodium-sulfur (Na/S) battery technology as the energy source in electric and hybrid vehicles that may affect the commercialization of Na/S batteries. This and the other reports on recycling, shipping, and vehicle safety are intended to help the Electric and Hybrid Propulsion Division of the Office of Transportation Technologies in the US Department of Energy (DOE/EHP) determine the direction of its research, development, and demonstration (RD&D) program for Na/S battery technology. The reports review the status of Na/S battery RD&Dmore » and identify potential hazards and risks that may require additional research or that may affect the design and use of Na/S batteries. This volume covers cell design and engineering as the basis of safety for Na/S batteries and describes and assesses the potential chemical, electrical, and thermal hazards and risks of Na/S cells and batteries as well as the RD&D performed, under way, or to address these hazards and risks. The report is based on a review of the literature and on discussions with experts at DOE, national laboratories and agencies, universities, and private industry. Subsequent volumes will address environmental, health, and safety issues involved in shipping cells and batteries, using batteries to propel electric vehicles, and recycling and disposing of spent batteries. The remainder of this volume is divided into two major sections on safety at the cell and battery levels. The section on Na/S cells describes major component and potential failure modes, design, life testing and failure testing, thermal cycling, and the safety status of Na/S cells. The section on batteries describes battery design, testing, and safety status. Additional EH&S information on Na/S batteries is provided in the appendices.« less

Digital Sensor Technology

DOE Office of Scientific and Technical Information (OSTI.GOV)

Thomas, Ken D.; Quinn, Edward L.; Mauck, Jerry L.

The nuclear industry has been slow to incorporate digital sensor technology into nuclear plant designs due to concerns with digital qualification issues. However, the benefits of digital sensor technology for nuclear plant instrumentation are substantial in terms of accuracy and reliability. This paper, which refers to a final report issued in 2013, demonstrates these benefits in direct comparisons of digital and analog sensor applications. Improved accuracy results from the superior operating characteristics of digital sensors. These include improvements in sensor accuracy and drift and other related parameters which reduce total loop uncertainty and thereby increase safety and operating margins. Anmore » example instrument loop uncertainty calculation for a pressure sensor application is presented to illustrate these improvements. This is a side-by-side comparison of the instrument loop uncertainty for both an analog and a digital sensor in the same pressure measurement application. Similarly, improved sensor reliability is illustrated with a sample calculation for determining the probability of failure on demand, an industry standard reliability measure. This looks at equivalent analog and digital temperature sensors to draw the comparison. The results confirm substantial reliability improvement with the digital sensor, due in large part to ability to continuously monitor the health of a digital sensor such that problems can be immediately identified and corrected. This greatly reduces the likelihood of a latent failure condition of the sensor at the time of a design basis event. Notwithstanding the benefits of digital sensors, there are certain qualification issues that are inherent with digital technology and these are described in the report. One major qualification impediment for digital sensor implementation is software common cause failure (SCCF).« less

Ethical issues when using social media for health outside professional relationships.

PubMed

DeCamp, Matthew

2015-04-01

Social media have the potential to revolutionize health and healthcare, but fulfilling this potential requires attention to the ethical issues social media may raise. This article reviews the major ethical issues arising when social media are used for research, public health, mobile health applications, and global health. It focuses on social media use outside fiduciary relationships between healthcare professionals and patients. Emphasis is given to the potential of social media in these contexts, the ethical issues relatively unique to each, and where possible how existing ethical principles and frameworks could help navigate these issues. In some cases social media create the circumstance for particular ethical issues but also facilitate managing them, such as in informed consent for research. In other cases, disagreement exists about whether social media - despite their potential - should be used for certain purposes, such as in public health surveillance (where confidentiality represents a significant ethical concern). In still others, ethical uncertainty exists about how social media will affect ethical issues, such as inequality in global health. As social media technologies continue to develop, identifying and managing the ethical issues they raise will be critical to their success in improving health while preserving fundamental ethical values.

2014-01-01

With devastating increase in population there is a great necessity to increase crop productivity of staple crops but the productivity is greatly affected by various abiotic stress factors such as drought, salinity. An attempt has been made a brief account on abiotic stress resistance of major cereal crops viz. In spite of good successes obtained on physiological and use molecular biology, the benefits of this high cost technology are beyond the reach of developing countries. This review discusses several morphological, anatomical, physiological, biochemical and molecular mechanisms of major cereal crops related to the adaptation of these crop to abiotic stress factors. It discusses the effect of abiotic stresses on physiological processes such as flowering, grain filling and maturation and plant metabolisms viz. photosynthesis, enzyme activity, mineral nutrition, and respiration. Though significant progress has been attained on the physiological, biochemical basis of resistance to abiotic stress factors, very little progress has been achieved to increase productivity under sustainable agriculture. Therefore, there is a great necessity of inter-disciplinary research to address this issue and to evolve efficient technology and its transfer to the farmers’ fields. PMID:25523172

Recently, the healthcare sector has shown a growing interest in information technologies. Two popular health IT (HIT) products are the electronic health record (EHR) and health information exchange (HIE) networks. The introduction of these tools is believed to improve care, but has also raised some important questions and legal and privacy issues. The implementation of these systems has not gone smoothly, and still faces some considerable barriers. This article reviews EHR and HIE to address these obstacles, and analyzes the current state of development and adoption in various countries around the world. Moreover, legal and ethical concerns that may be encountered by EHR users and purchasers are reviewed. Finally, links and interrelations between EHR and HIE and several quality of care issues in today's healthcare domain are examined with a focus on EHR and HIE in the emergency department (ED), whose unique characteristics makes it an environment in which the implementation of such technology may be a major contributor to health, but also faces substantial challenges. The paper ends with a discussion of specific policy implications and recommendations based on an examination of the current limitations of these systems. Copyright © 2014 Elsevier Ireland Ltd.

Solid-state, crystallographic purity and careful monitoring of the polymorphism of drugs and excipients are currently an integral part of the development of modern drug delivery systems. The reproducible preparation of organic crystals in a specific form and size is a major issue that must be addressed. A recent approach for obtaining pharmaceutical materials in pure physical form is represented by the technologies based on supercritical fluids. The present work aims to provide a critical review of the recent advances in the use of supercritical fluids for the preparation and control of the specific physical form of pharmaceutical substances with particular attention to those fluids used for drug delivery systems. These innovative technologies are highly promising for future application in particle design and engineering.

Binary optics: Trends and limitations

NASA Technical Reports Server (NTRS)

Farn, Michael W.; Veldkamp, Wilfrid B.

1993-01-01

We describe the current state of binary optics, addressing both the technology and the industry (i.e., marketplace). With respect to the technology, the two dominant aspects are optical design methods and fabrication capabilities, with the optical design problem being limited by human innovation in the search for new applications and the fabrication issue being limited by the availability of resources required to improve fabrication capabilities. With respect to the industry, the current marketplace does not favor binary optics as a separate product line and so we expect that companies whose primary purpose is the production of binary optics will not represent the bulk of binary optics production. Rather, binary optics' more natural role is as an enabling technology - a technology which will directly result in a competitive advantage in a company's other business areas - and so we expect that the majority of binary optics will be produced for internal use.

2010-01-01

In this article, we review gas sensor application of one-dimensional (1D) metal-oxide nanostructures with major emphases on the types of device structure and issues for realizing practical sensors. One of the most important steps in fabricating 1D-nanostructure devices is manipulation and making electrical contacts of the nanostructures. Gas sensors based on individual 1D nanostructure, which were usually fabricated using electron-beam lithography, have been a platform technology for fundamental research. Recently, gas sensors with practical applicability were proposed, which were fabricated with an array of 1D nanostructures using scalable micro-fabrication tools. In the second part of the paper, some critical issues are pointed out including long-term stability, gas selectivity, and room-temperature operation of 1D-nanostructure-based metal-oxide gas sensors.

Tracking organ motion due to respiration is important for precision treatments in interventional radiology and radiation oncology, among other areas. In interventional radiology, the ability to track and compensate for organ motion could lead to more precise biopsies for applications such as lung cancer screening. In radiation oncology, image-guided treatment of tumors is becoming technically possible, and the management of organ motion then becomes a major issue. This paper will review the state-of-the-art in respiratory motion and present two related clinical applications. Respiratory motion is an important topic for future work in image-guided surgery and medical robotics. Issues include how organs move due to respiration, how much they move, how the motion can be compensated for, and what clinical applications can benefit from respiratory motion compensation. Technology that can be applied for this purpose is now becoming available, and as that technology evolves, the subject will become an increasingly interesting and clinically valuable topic of research.

2016-01-01

Two issues pertaining to the effective implementation of health information technologies (HITs) in U.S. hospitals are examined. First, which information technology (IT) system is better--a homegrown or an outsourced one? In the second issue, the critical role of in-house IT expertise/capabilities in the effective implementation of HITs is investigated. The data on type of HIT system and IT expertise/capabilities were collected from a national sample of senior executives of U.S. hospitals. The data on quality of patient care were gathered from the Hospital Compare Web site. The quality of patient care was significantly higher in hospitals deploying a homegrown HIT system than hospitals deploying an outsourced HIT system. Furthermore, the professional competence and compelling vision of the chief information officer was found to be a major driver of another key IT capability of hospitals-professionalism of IT staff. The positive relationship of professionalism of IT staff with quality of patient care was mediated by proactive employee behavior. A homegrown HIT system achieves better quality of patient care than an outsourced one. The chief information officer's IT vision and the professional expertise and professionalism of IT staff are important IT capabilities in U.S. hospitals.

The major design related features of each generic plant system were characterized in a catalog. Based on the catalog and requirements data, approximately 17 designs and cost estimates were developed for MBG and alternate products. A series of generic trade studies was conducted to support all of the design studies. A set of cost and programmatic analyses were conducted to supplement the designs. The cost methodology employed for the design and sensitivity studies was documented and implemented in a computer program. Plant design and construction schedules were developed for the K-T, Texaco, and B&W MBG plant designs. A generic work breakdown structure was prepared, based on the K-T design, to coincide with TVA's planned management approach. An extensive set of cost sensitivity analyses was completed for K-T, Texaco, and B&W design. Product price competitiveness was evaluated for MBG and the alternate products. A draft management policy and procedures manual was evaluated. A supporting technology development plan was developed to address high technology risk issues. The issues were identified and ranked in terms of importance and tractability, and a plan developed for obtaining data or developing technology required to mitigate the risk.

In the field of science and technology studies, recent works have analyzed the multiplication of promises and predictions as a major evolution of science management. The authors involved in this "sociology of technical expectations" have documented the role played by promises in the elaboration of scientific projects and their impact on the social reception of scientific issues. Yet, little attention has been paid to the predictions regarding undesirable technological futures. This article proposes therefore to analyze the discursive and argumentative practices through which journalists, scientists, and politicians denounce and propose to counter a public issue "which does not exist yet": gene doping (no case of gene doping has been recorded to date). After a literature review of the field of the sociology of technological expectations and a presentation of the corpus, the article describes the structure of predictions and analyzes the discursive strategies according to which social actors predict a disaster in the making. The analysis is based on the study of media discourses about gene doping, in a corpus of 163 French language articles from European newspapers, published between 1998 and 2012. © The Author(s) 2014.

Background : Earthquakes causing significant damage have occurred frequently in China, producing enormous health losses, damage to the environment and public health issues. Timely public health response is crucial to reduce mortality and morbidity and promote overall effectiveness of rescue efforts after a major earthquake. Methods : A rapid assessment framework was established based on GIS technology and high-resolution remote sensing images. A two-step casualties and injures estimation method was developed to evaluate health loss with great rapidity. Historical data and health resources information was reviewed to evaluate the damage condition of medical resources and public health issues. Results : The casualties and injures are estimated within a few hours after an earthquake. For the Wenchuan earthquake, which killed about 96,000 people and injured about 288,000, the estimation accuracy is about 77%. 242/294 (82.3%) of the medical existing institutions were severely damaged. About 40,000 tons of safe drinking water was needed every day to ensure basic living needs. The risk of water-borne and foodborne disease, respiratory and close contact transmission disease is high. For natural foci diseases, the high-risk area of schistosomiasis was mapped in Lushan County as an example. Finally, temporary settlements for victims of earthquake were mapped. Conclusions : High resolution Earth observation technology can provide a scientific basis for public health emergency management in the major disasters field, which will be of great significance in helping policy makers effectively improve health service ability and public health emergency management in prevention and control of infectious diseases and risk assessment.

Multi-patterning has been adopted widely in high volume manufacturing as 193 immersion extension, and it becomes realistic solution of nano-order scaling. In fact, it must be key technology on single directional (1D) layout design [1] for logic devise and it becomes a major option for further scaling technique in SAQP. The requirement for patterning fidelity control is getting savior more and more, stochastic fluctuation as well as LER (Line edge roughness) has to be micro-scopic observation aria. In our previous work, such atomic order controllability was viable in complemented technique with etching and deposition [2]. Overlay issue form major potion in yield management, therefore, entire solution is needed keenly including alignment accuracy on scanner and detectability on overlay measurement instruments. As EPE (Edge placement error) was defined as the gap between design pattern and contouring of actual pattern edge, pattern registration in single process level must be considerable. The complementary patterning to fabricate 1D layout actually mitigates any process restrictions, however, multiple process step, symbolized as LELE with 193-i, is burden to yield management and affordability. Recent progress of EUV technology is remarkable, and it is major potential solution for such complicated technical issues. EUV has robust resolution limit and it must be definitely strong scaling driver for process simplification. On the other hand, its stochastic variation such like shot noise due to light source power must be resolved with any additional complemented technique. In this work, we examined the nano-order CD and profile control on EUV resist pattern and would introduce excellent accomplishments.

Mechanical pumps for superfluid helium transfer in space

NASA Technical Reports Server (NTRS)

Izenson, M. G.; Swift, W. L.

1988-01-01

Two alternate mechanical pump concepts have been identified for the transfer of superfluid helium in space. Both pumps provide flow at sufficient head and have operating characteristics suitable for the Space Infrared Telescope Facility (SIRTF) refill mission. One pump operates at a relatively low speed and utilizes mechanical roller bearings, while the other operates at a higher rotational speed using either electromagnetic or tilting pad gas-dynamic bearings. The use of gas bearings requires transfer of normal helium so that the gas pressure within the pump casing is high enough to operate the bearings. The operating characteristics of both pumps are predicted, the dimensions are estimated and major technology issues are identified. The major issues for each pump design are cavitation performance and bearing development. Roller bearings require quantified reliability for operation in space while electromagnetic bearings require basic development as well as a complex control system. The low speed pump has significantly poorer hydraulic efficiency than the high speed pump.

The Development of Human Factor Guidelines for Unmanned Aircraft System Control Stations

Hobbs, Alan

2014-01-01

Despite being referred to as unmanned some of the major challenges confronting unmanned aircraft systems (UAS) relate to human factors. NASA is conducting research to address the human factors relevant to UAS access to non-segregated airspace. This work covers the issues of pilot performance, interaction with ATC, and control station design. A major outcome of this research will be recommendations for human factors design guidelines for UAS control stations to support routine beyond-line-of-sight operations in the US national airspace system (NAS). To be effective, guidelines must be relevant to a wide range of systems, must not be overly prescriptive, and must not impose premature standardization on evolving technologies. In developing guidelines, we recognize that existing regulatory and guidance material may already provide adequate coverage of certain issues. In other cases suitable guidelines may be found in existing military or industry human factors standards. In cases where appropriate existing standards cannot be identified, original guidelines will be proposed.

Liquid lithium loop system to solve challenging technology issues for fusion power plant

Here, steady-state fusion power plant designs present major divertor technology challenges, including high divertor heat flux both in steady-state and during transients. In addition to these concerns, there are the unresolved technology issues of long term dust accumulation and associated tritium inventory and safety issues. It has been suggested that radiation-based liquid lithium (LL) divertor concepts with a modest lithium-loop could provide a possible solution for these outstanding fusion reactor technology issues, while potentially improving reactor plasma performance. The application of lithium (Li) in NSTX resulted in improved H-mode confinement, H-mode power threshold reduction, and reduction in the divertor peakmore » heat flux while maintaining essentially Li-free core plasma operation even during H-modes. These promising results in NSTX and related modeling calculations motivated the radiative liquid lithium divertor (RLLD) concept and its variant, the active liquid lithium divertor concept (ARLLD), taking advantage of the enhanced or non-coronal Li radiation in relatively poorly confined divertor plasmas. To maintain the LL purity in a 1 GW-electric class fusion power plant, a closed LL loop system with a modest circulating capacity of ~ 1 liter/second (l/sec) is envisioned. We examined two key technology issues: 1) dust or solid particle removal and 2) real time recovery of tritium from LL while keeping the tritium inventory level to an acceptable level. By running the LL-loop continuously, it can carry the dust particles and impurities generated in the vacuum vessel to the outside where the dust / impurities can be removed by relatively simple dust filter, cold trap and/or centrifugal separation systems. With ~ 1 l/sec LL flow, even a small 0.1% dust content by weight (or 0.5 g per sec) suggests that the LL-loop could carry away nearly 16 tons of dust per year. In a 1 GW-electric (or ~ 3 GW fusion power) fusion power plant, about 0.5 g / sec of tritium is needed to maintain the fusion fuel cycle assuming ~ 1 % fusion burn efficiency. It appears feasible to recover tritium (T) in real time from LL while maintaining an acceptable T inventory level. Laboratory tests are being conducted to investigate T recovery feasibility with the surface cold trap (SCT) concept.« less

The present study of current telemedicine users is a unique attempt to understand the barriers and motivational factors related to the utilization of telemedicine. A survey of emergency and critical care remote presence telemedicine users was conducted to determine the factors that motivate and the barriers that impede the acceptance and maintenance of a robotic telemedicine (RTM) program. The majority of the survey users were in the Emergency Department or in the Intensive Care Unit. E-mail invitations were sent to 483 individuals representing 63 healthcare institutions and groups in North America and Europe. Respondents were directed to a Web-based survey. The survey consisted of 96 separate questions, addressing user familiarity and 5-point Likert scales, addressing issues spanning the conceptual and practical issues surrounding adoption of telemedicine. A total of 106 surveys were completed, representing an individual response rate of 21.9% but an institutional response rate of 60.3%. More than two-thirds of the respondents were physicians who participated in active RTM programs. Across seven different topics related to barriers to implementing RTM, the majority of all respondents indicated that cultural issues did not constitute meaningful hurdles, technological matters were generally favorable, and that most personnel were agreeable to both achieving the buy-in to start an RTM program and to maintaining RTM once started. However, respondents proclaimed that RTM's success was still hampered by licensing, credentialing, and malpractice protection, as well as costs, billing, and reimbursement issues. Achieving immediate patient access, overcoming service gaps, improving quality, providing clinical support, maintaining patient satisfaction, and adhering to practice guidelines were viewed as significant motives for RTM implementation. The leading applications of RTM included emergency response and consultation. The patients, physicians, nurses, nor hospital executives served as barriers to implementation. However, licensing, costs for technology, and reimbursement for RTM continue to impede progress.

Implications of Outside-the-Box Technologies on Future Space Exploration and Colonization

NASA Astrophysics Data System (ADS)

Loder, Theodore C.

2003-01-01

In general, planning for future manned space exploration either to the moon, Mars, or an asteroid has depended on a somewhat linear extrapolation of our present technologies. Two major prohibitive cost issues regarding such planning are payload lift and in-flight energy generation. The costs of these in both engineering and actual flight costs, coupled with the planning necessary to carry out such exploration have prevented us from actively moving forward. Although, it will be worthwhile to continue to plan for such exploration using ``present'' technologies, I recommend that planning be concerned mainly with mission strategies and goals utilizing both present technology and totally new energy breakthroughs. There are presently in research and development an entire suite of relevant outside-the-box technologies which will include both zero point energy generation and antigravity technologies that will replace our present solar/nuclear/fuel cell energy technologies and liquid/solid fuel rockets. This paper describes some of these technologies, the physics behind them and their potential use for manned space exploration. The companies and countries that first incorporate these technologies into their space programs will lead the way in exploring and colonizing space.

Since January 1997, the US/China Energy and Environmental Technology Center (EETC) in Beijing has been jointly operated by Tulane University and Tsinghua University. EETC is established to encourage the adoption of technologies for energy production with improved environmental performance which are essential for supporting economic growth and managing the Global Warming and Climate Change issues. International cooperation is critical to insure the environmental and energy security on a global basis. For example, the US has acquired a great deal of useful experience in clean coal technology which has been demonstrated with major utilities in commercial operations. The adaption of, andmore » the installation of, clean coal technology should be given high priority. Worldwide, the continuous exchange of information and technology between developed and developing nations relating to the current and future clean coal technologies is of great importance. Developed nations which possess environmental responsive technologies and financial resources should work closely with developing nations to facilitate technology transfer and trade of technologies. International cooperation will lower the cost of deploying clean coal technologies directed toward the clean production of energy. This paper presents the updated activities of EETC on facilitating technology transfer and promoting the clean use of coal to satisfy growing energy demand in China.« less

We report here on the major commercialization aspects of thin-film photovoltaic (PV) technologies based on CIGS and CdTe (a-Si and thin-Si are also reported for completeness on the status of thin-film PV). Worldwide silicon (Si) based PV technologies continues to dominate at more than 94% of the market share, with the share of thin-film PV at less than 6%. However, the market share for thin-film PV in the United States continues to grow rapidly over the past several years and in CY 2006, they had a substantial contribution of about 44%, compared to less than 10% in CY 2003. Inmore » CY 2007, thin-film PV market share is expected to surpass that of Si technology in the United States. Worldwide estimated projections for CY 2010 are that thin-film PV production capacity will be more than 3700 MW. A 40-MW thin-film CdTe solar field is currently being installed in Saxony, Germany, and will be completed in early CY 2009. The total project cost is Euro 130 million, which equates to an installed PV system price of Euro 3.25/-watt averaged over the entire solar project. This is the lowest price for any installed PV system in the world today. Critical research, development, and technology issues for thin-film CIGS and CdTe are also elucidated in this paper.« less

The inclusion of Science Technology Society topics in junior high school earth science textbooks

Fadhli, Fathi Ali

2000-10-01

The Science Technology Society (STS) approach is a major science education reform through which a scientifically literate citizen could be produced. The teaching of science through STS approach is centered on science and technology related issues and problems. The purpose of this study was to analyze five earth science textbooks published in the 1990's for their inclusion of twelve sciences and technology related issues and problems and for their inclusion of activities focused on STS. The selected earth science textbooks were; Scott Foresman, Heath, Holt, Merrill and Prentice-Hall. The targeted twelve issues and problems were identified by Bybee (1987), as the most important global science and technology related issues and problems. The numbers of full text pages devoted to each topic were determined by classifying each segment to one of the targeted topics. In addition, the numbers of STS activities were also determined by using criteria developed for this study. ANOVA statistical analyses and t-tests showed that the analyzed earth science textbooks treated the studied STS issues and problems and treated the STS activities differently. It was found that six of the studied issues and problems were constantly receiving more attention in all the analyzed earth science textbooks than the rest of the topics. These topics were; Air Quality and Atmosphere, Energy Shortages, Water Resources, Land Use, Hazardous Substances, and Mineral Resources. The overall results revealed that only an average of 8.82% of the text pages in all the analyzed earth science textbooks were devoted to STS topics and 5.49% of the activities in all the analyzed earth science textbooks were focused on STS topics. However, none of the activities focused on STS topics were presented in STS approach as defined by NSTA. The percentage of STS topics inclusion and the percentage of activities focused on STS topics were considered to be very low. Accordingly, the objectives and goals of STS approach will not be achieved through using the analyzed earth science textbooks. The low percentages of STS activities and topics indicated also that the STS approach would not be fairly presented in science classrooms as long as science teachers depend on science textbooks 90% of their teaching time. Moreover, the results of this study revealed also that the inclusion of STS approach in science textbooks is still considered to be very low despite the support provided to the STS approach by science teachers, educators, organizations, and education departments and also despite of the publishing of Project Syntheses (1977) since twenty eight years ago.

Why Patient Matching Is a Challenge: Research on Master Patient Index (MPI) Data Discrepancies in Key Identifying Fields

Just, Beth Haenke; Marc, David; Munns, Megan; Sandefer, Ryan

2016-01-01

Patient identification matching problems are a major contributor to data integrity issues within electronic health records. These issues impede the improvement of healthcare quality through health information exchange and care coordination, and contribute to deaths resulting from medical errors. Despite best practices in the area of patient access and medical record management to avoid duplicating patient records, duplicate records continue to be a significant problem in healthcare. This study examined the underlying causes of duplicate records using a multisite data set of 398,939 patient records with confirmed duplicates and analyzed multiple reasons for data discrepancies between those record matches. The field that had the greatest proportion of mismatches (nondefault values) was the middle name, accounting for 58.30 percent of mismatches. The Social Security number was the second most frequent mismatch, occurring in 53.54 percent of the duplicate pairs. The majority of the mismatches in the name fields were the result of misspellings (53.14 percent in first name and 33.62 percent in last name) or swapped last name/first name, first name/middle name, or last name/middle name pairs. The use of more sophisticated technologies is critical to improving patient matching. However, no amount of advanced technology or increased data capture will completely eliminate human errors. Thus, the establishment of policies and procedures (such as standard naming conventions or search routines) for front-end and back-end staff to follow is foundational for the overall data integrity process. Training staff on standard policies and procedures will result in fewer duplicates created on the front end and more accurate duplicate record matching and merging on the back end. Furthermore, monitoring, analyzing trends, and identifying errors that occur are proactive ways to identify data integrity issues. PMID:27134610

A quasi-Delphi study on technological barriers to the uptake of hydrogen as a fuel for transport applications-Production, storage and fuel cell drivetrain considerations

NASA Astrophysics Data System (ADS)

Hart, David; Anghel, Alexandra T.; Huijsmans, Joep; Vuille, François

The introduction of hydrogen in transport, particularly using fuel cell vehicles, faces a number of technical and non-technical hurdles. However, their relative importance is unclear, as are the levels of concern accorded them within the expert community conducting research and development within this area. To understand what issues are considered by experts working in the field to have significant potential to slow down or prevent the introduction of hydrogen technology in transport, a study was undertaken, primarily during 2007. Three key technology areas within hydrogen transport were selected - hydrogen storage, fuel cell drivetrains, and small-scale hydrogen production - and interviews with selected experts conducted. Forty-nine experts from 34 organisations within the fuel cell, automotive, industrial gas and other related industries participated, in addition to some key academic and government figures. The survey was conducted in China, Japan, North America and Europe, and analysed using conventional mathematical techniques to provide weighted and averaged rankings of issues viewed as important by the experts. It became clear both from the interviews and the subsequent analysis that while a primary concern in China was fundamental technical performance, in the other regions cost and policy were rated more highly. Although a few individual experts identified possible technical showstoppers, the overall message was that pre-commercial hydrogen fuel cell vehicles could realistically be on the road in tens of thousands within 5 years, and that full commercialisation could take place within 10-15 years, without the need for radical technical breakthroughs. Perhaps surprisingly, the performance of hydrogen storage technologies was not viewed as a showstopper, though cost was seen as a significant challenge. Overall, however, coherent policy development was more frequently identified as a major issue to address.

Classifying health information technology patient safety related incidents - an approach used in Wales.

PubMed

Warm, D; Edwards, P

2012-01-01

Interest in the field of patient safety incident reporting and analysis with respect to Health Information Technology (HIT) has been growing over recent years as the development, implementation and reliance on HIT systems becomes ever more prevalent. One of the rationales for capturing patient safety incidents is to learn from failures in the delivery of care and must form part of a feedback loop which also includes analysis; investigation and monitoring. With the advent of new technologies and organizational programs of delivery the emphasis is increasingly upon analyzing HIT incidents. This thematic review had two objectives, to test the applicability of a framework specifically designed to categorize HIT incidents and to review the Welsh incidents as communicated via the national incident reporting system in order to understand their implications for healthcare. The incidents were those reported as IT/ telecommunications failure/ overload. Incidents were searched for within a national reporting system using a standardized search strategy for incidents occurring between 1(st) January 2009 and 31(st) May 2011. 149 incident reports were identified and classified. The majority (77%) of which were machine related (technical problems) such as access problems; computer system down/too slow; display issues; and software malfunctions. A further 10% (n = 15) of incidents were down to human-computer interaction issues and 13% (n = 19) incidents, mainly telephone related, could not be classified using the framework being tested. On the basis of this review of incidents, it is recommended that the framework be expanded to include hardware malfunctions and the wrong record retrieved/missing data associated with a machine output error (as opposed to human error). In terms of the implications for clinical practice, the incidents reviewed highlighted critical issues including the access problems particularly relating to the use of mobile technologies.

2012-11-01

Intensive industrialisation, inadequate disposal, large-scale manufacturing activities and leaks of organic compounds have resulted in long-term persistent sources of contamination of soil and groundwater. This is a major environmental, policy and health issue because of adverse effects of contaminants on humans and ecosystems. Current technologies for remediation of contaminated sites include chemical and physical remediation, incineration and bioremediation. With recent advancements, bioremediation offers an environmentally friendly, economically viable and socially acceptable option to remove contaminants from the environment. Three main approaches of bioremediation include use of microbes, plants and enzymatic remediation. All three approaches have been used with some success but are limited by various confounding factors. In this paper, we provide a brief overview on the approaches, their limitations and highlights emerging technologies that have potential to revolutionise the enzymatic and plant-based bioremediation approaches.

Legal issues of the electronic dental record: security and confidentiality.

Szekely, D G; Milam, S; Khademi, J A

1996-01-01

Computer-based, electronic dental record keeping involves complex issues of patient privacy and the dental practitioner's ethical duty of confidentiality. Federal and state law is responding to the new legal issues presented by computer technology. Authenticating the electronic record in terms of ensuring its reliability and accuracy is essential in order to protect its admissibility as evidence in legal actions. Security systems must be carefully planned to limit access and provide for back-up and storage of dental records. Carefully planned security systems protect the patient from disclosure without the patient's consent and also protect the practitioner from the liability that would arise from such disclosure. Human errors account for the majority of data security problems. Personnel security is assured through pre-employment screening, employment contracts, policies, and staff education. Contracts for health information systems should include provisions for indemnification and ensure the confidentiality of the system by the vendor.

The National Aeronautics and Space Administration has developed a globally-distributed complex of earth resources data bases since LANDSAT 1 was launched in 1972. NASA envisages considerable growth in the number, extent, and complexity of such data bases, due to the improvements expected in its remote sensing data rates, and the increasingly multidisciplinary nature of its scientific investigations. Work already has begun on information systems to support multidisciplinary research activities based on data acquired by the space station complex and other space-based and terrestrial sources. In response to a request from NASA's former Associate Administrator for Space Science and Applications, the National Research Council convened a committee in June 1985 to identify the critical issues involving information systems support to space science and applications. The committee has suggested that OSSA address four major information systems issues; centralization of management functions, interoperability of user involvement in the planning and implementation of its programs, and technology.

NASA Technical Reports Server (NTRS)

1989-01-01

Important and fundamental scientific progress can be attained through space observations in the wavelengths longward of 1 micron. The formation of galaxies, stars, and planets, the origin of quasars and the nature of active galactic nuclei, the large scale structure of the Universe, and the problem of the missing mass, are among the major scientific issues that can be addressed by these observations. Significant advances in many areas of astrophysics can be made over the next 20 years by implementing the outlined program. This program combines large observatories with smaller projects to create an overall scheme that emphasized complementarity and synergy, advanced technology, community support and development, and the training of the next generation of scientists. Key aspects of the program include: the Space Infrared Telescope Facility; the Stratospheric Observatory for Infrared Astronomy; a robust program of small missions; and the creation of the technology base for future major observatories.

Australian defence requirements and initiatives in smart materials and structures

Wilson, Alan R.; Galea, Stephen C.; Scala, Christine; Wong, Albert

2002-11-01

The Australian Defence Force is increasingly facing escalating costs on through-life support for major platforms (ships, aircraft and land vehicles). The application of smart materials and structures technologies in platform management systems is seen as a very promising approach to reduce these costs and to potentially achieve significant enhancement of platform capability. A new DSTO Key Initiative, 'Smart Materials and Structures', has been recently developed and funded to address these technologies. The Initiative will build on and grow the current activities within DSTO and promote collaboration with external Australian institutes and industry. This paper will present an overview of the Initiative and the generic sensor and system issues inherent in the 'whole-of-platform' and 'whole-of-life' monitoring and management of major defence platforms. Examples for some particular elements of this will be drawn from current work in DSTO. Other presentations in the conference will cover the technical and scientific aspects of these in more detail.

Ferroelectric random access memory (FeRAM) is an attractive candidate technology for embedded nonvolatile memory, especially in applications where low power and high program speed are important. Market introduction of high-density FeRAM is, however, lagging behind standard complementary metal-oxide semiconductor (CMOS) because of the difficult integration technology. This paper discusses the major integration issues for high-density FeRAM, based on SrBi2Ta2O9 (strontium bismuth tantalate or SBT), in relation to the fabrication of our stacked cell structure. We have worked in the previous years on the development of SBT-FeRAM integration technology, based on a so-called pseudo-three-dimensional (3D) cell, with a capacitor that can be scaled from quasi two-dimensional towards a true three-dimensional capacitor where the sidewalls will importantly contribute to the signal. In the first phase of our integration development, we integrated our FeRAM cell in a 0.35μm CMOS technology. In a second phase, then, possibility of scaling of our cell is demonstrated in 0.18μm technology. The excellent electrical and reliability properties of the small integrated ferroelectric capacitors prove the feasibility of the technology, while the verification of the potential 3D effect confirms the basic scaling potential of our concept beyond that of the single-mask capacitor. The paper outlines the different material and technological challenges, and working solutions are demonstrated. While some issues are specific to our own cell, many are applicable to different stacked FeRAM cell concepts, or will become more general concerns when more developments are moving into 3D structures.

Enhanced imaging technologies such as narrow band imaging, flexible spectral imaging color enhancement, i-Scan, confocal laser endomicroscopy, and optical coherence tomography are readily available for use by endoscopists in routine clinical practice. In November 2014, the American Gastroenterological Association's Center for GI Innovation and Technology conducted a 2-day workshop to discuss endoscopic image enhancement technologies, focusing on their role in 2 specific clinical conditions (colon polyps and Barrett's esophagus) and on issues relating to training and implementation of these technologies (white papers). Although the majority of the studies that use enhanced imaging technologies have been positive, these techniques ideally need to be validated in larger cohorts and in community centers. As it stands today, detailed endoscopic examination with high-definition white-light endoscopy and random 4-quadrant biopsy remains the standard of care. However, the workshop panelists agreed that in the hands of endoscopists who have met the preservation and incorporation of valuable endoscopic innovation thresholds (diagnostic accuracy) with enhanced imaging techniques (specific technologies), use of the technique in Barrett's esophagus patients is appropriate.

Computer-Assisted Personal Interviewing (CAPI), coupled with the use of mobile and wireless technology, is growing as a data collection methodology. Nepal, a geographically diverse and resource-scarce country, implemented the 2011 Nepal Demographic and Health Survey, a nationwide survey of major health indicators, using tablet personal computers (tablet PCs) and wireless technology for the first time in the country. This paper synthesizes responses on the benefits and challenges of using new technology in such a challenging environment from the 89 interviewers who administered the survey. Overall, feedback from the interviewers indicate that the use of tablet PCs and wireless technology to administer the survey demonstrated potential to improve data quality and reduce data collection time-benefits that outweigh manageable challenges, such as storage and transport of the tablet PCs during fieldwork, limited options for confidential interview space due to screen readability issues under direct sunlight, and inconsistent electricity supply at times. The introduction of this technology holds great promise for improving data availability and quality, even in a context with limited infrastructure and extremely difficult terrain.

Sondreal, E.A.

1982-01-01

The most important market for lignite will continue to be the electric utility industry, where it is used to fuel large pc-fired boilers serving major regional power grids. However, the growth of this market and thechnology is being challenged by new and more stringent environmental control requirements, including the international concern over acid rain. Environmental and economic issues could either encourage or limit the development of a synfuels market for lignite depending on the cost effectiveness of the technological solutions that are developed. Clearly the United States needs to develop its coal resources to reduce dependence on imported oil. However,more » demand for coal derived substitute petroleum will be constrained by cost for the forseeable future. Government policy initiatives and new technology will be the keys to removing these constraints in the decades ahead. A crossover point with respect to petroleum and natural gas will be reached at some point in the future, which will allow synthetic fuels to penetrate the markets now served by oil and gas. Those of us who are today concerned with the development of lignite resources can look forward to participating in the major synfuels market that will emerge when those economic conditions are realized.« less

Hofmann, Bjørn

2005-01-01

Although ethics has been on the agenda in health technology assessment (HTA) since its inception, the integration of moral issues is still not standard and is performed in a vast variety of ways. Therefore, there is a need for a procedure for integrating moral issues in HTA. Literature review of existing approaches together with application of various theories in moral philosophy and axiology. The article develops a set of questions that addresses a wide range of moral issues related to the assessment and implementation of health technology. The issues include general moral issues and moral issues related to stakeholders, methodology, characteristics of technology, and to the HTA process itself. The questions form a kind of checklist for use in HTAs. The presented approach for integrating moral issues in HTA has a broad theoretical foundation and has shown to be useful in practice. Integrating ethical issues in HTAs can be of great importance with respect to the dissemination of HTA results and in efficient health policy making.

Introduction The purpose of this study is to examine the role of information and communication technology (ICT) in enhancing community outreach, academic and research collaboration, and education and support services (IT-CARES) in an academic setting. Methods A survey was deployed to assess the ICT needs in an academic setting. The survey was developed using the Delphi methodology. Questionnaire development was initiated by asking key stakeholders involved in community outreach, academic, research, education, and support to provide feedback on current ICT issues and future recommendations for relevant ICT tools that would be beneficial to them in their job, and to capture current ICT issues. Participants were asked to rate the level of importance of each ICT question on five-point Likert scales. Results The survey was sent to 359 participants, including faculty, staff, and students. The total number of respondents was 96, for a 27 percent response rate. The majority of the participants (54.1 percent, n = 46) placed a high importance on learning the available research capabilities of the college. The majority of the participants placed moderate (43.5 percent, n = 37) to high importance (40 percent, n = 34) on having an intranet that could support collaborative grant writing. A majority of the participants attributed high importance to learning to interact with the online learning management system Blackboard. A majority of the participants agreed that social media should being more actively utilized for diverse activities for academic and research purposes. Conclusion The study helped to identify the current needs and challenges faced by professionals and students when interacting with ICT. More research is needed in order to effectively integrate the use of ICT in the field of higher education, especially related to the modern global public health context. PMID:24159275

How rich is Australia's minerals endowment and is it adequate to sustain a major role in meeting international demand?

NASA Astrophysics Data System (ADS)

Lambert, I. B.

2012-04-01

Dr Ian Lambert, Geoscience Australia and Secretary General 34th International Geological Congress Australia has comparative advantages in production of mineral commodities compared to most other countries. These stem from its rich and diverse mineral endowment; availability of regional scale (pre-competitive) geoscience information to lower the risks of exploration; advances in exploration, mining and processing technologies; skilled work force; generally benign physical conditions; and low population density. Building on these strengths, Australia is a major producer and exporter of a wide range of mineral and energy commodities to global markets. Given that demand for most major commodities is likely to continue, and that there will be growing markets for some other commodities, Australia needs to have a strategic view of what is likely to be available for mining. Further, Australia (and the world) needs to be attuned to issues that need to be faced in meeting international demand for commodities in the long term. This presentation outlines how Australia's national minerals inventory is compiled. It discusses trends for Australia's identified mineral resources for major commodities, and how these compare with other major mining nations. It then considers some significant issues in relation to sustaining a strong mining sector - in the medium to long term this requires a strategic approach to achieve goals such as more effective/lower risk exploration particularly in greenfields regions; well-Informed decisions on mining proposals; ongoing significant improvements in efficiencies of energy, water and land use.

EPA Pesticide Factsheets

The Trans-Atlantic Research and Development Interchange on Sustainability (TARDIS) has been bringing together a select group of scientists and engineers for in-depth discussions on sustainability on a bi-annual basis since 2004. TARDIS 2014 included twenty eight individuals from across the globe discussing issues related to progress towards sustainability. The discussion included policies, technologies, societal structure and norms, business practices and culture, and time-frames. As discussed later, the focus was on four questions: (1) what progress has been accomplished in sustainability? (2) why has there not been more progress in moving societies towards sustainability? (3) what are the road-blocks to progress towards sustainability? (4) what are the policies, technologies, and other changes that are needed to make further progress towards sustainability? One salient conclusion from TARDIS 2014 is that while sustainability has entered mainstream thinking, significant social, economic, technological, and business barriers remain to further progress towards a sustainable path as discussed throughout this report. The Trans-Atlantic Research and Development Interchange on Sustainability is a bi-annual workshop alternatively held in the United States and Austria. The purpose is to bring the best thinkers from across the globe to discuss, explore, and clarify major issues related to sustainability.

Pawluk, Dianne T V; Adams, Richard J; Kitada, Ryo

2015-01-01

This paper considers issues relevant for the design and use of haptic technology for assistive devices for individuals who are blind or visually impaired in some of the major areas of importance: Braille reading, tactile graphics, orientation and mobility. We show that there is a wealth of behavioral research that is highly applicable to assistive technology design. In a few cases, conclusions from behavioral experiments have been directly applied to design with positive results. Differences in brain organization and performance capabilities between individuals who are "early blind" and "late blind" from using the same tactile/haptic accommodations, such as the use of Braille, suggest the importance of training and assessing these groups individually. Practical restrictions on device design, such as performance limitations of the technology and cost, raise questions as to which aspects of these restrictions are truly important to overcome to achieve high performance. In general, this raises the question of what it means to provide functional equivalence as opposed to sensory equivalence.

2014-09-01

The high per capita generation of solid waste and the environmental problems in major rural communities of Ensenada, Baja California, have prompted authorities to seek alternatives for waste treatment. In the absence of a selection methodology, three technologies of waste treatment with energy recovery (an anaerobic digester, a downdraft gasifier, and a plasma gasifier) were evaluated, taking the broader social, political, economic, and environmental issues into considerations. Using the scientific literature as a baseline, interviews with experts, decision makers and the community, and waste stream studies were used to construct a hierarchy that was evaluated by the analytic hierarchy process. In terms of the criteria, judgments, and assumptions made in the model, the anaerobic digester was found to have the highest rating and should consequently be selected as the waste treatment technology for this area. The study results showed low sensitivity, so alternative scenarios were not considered. The methodology developed in this study may be useful for other governments who wish to assess technologies to select waste treatment.

Science education often adopts a narrow view of science that assumes the lay public is ignorant, which seemingly justifies a science education limited to a promotional narrative of progress in the form of scientific knowledge void of meaningful social context. We propose that to prepare students as future concerned citizens of a technoscientific society, science education should be informed by science, technology, and society (STS) perspectives. An STS-informed science education, in our view, will include the following curricular elements: science controversy education, gender issues, historical perspective, and a move away from a Eurocentric view by looking into the distinctive patterns of other regional (in this case of Taiwan, East Asian) approaches to science, technology, and medicine. This article outlines the significance of some major STS studies as a means of illustrating the ways in which STS perspectives can, if incorporated into science education, enhance our understanding of science and technology and their relationships with society.

The media and access issues: content analysis of Canadian newspaper coverage of health policy decisions.

PubMed

Rachul, Christen; Caulfield, Timothy

2015-08-25

Previous studies have demonstrated how the media has an influence on policy decisions and healthcare coverage. Studies of Canadian media have shown that news coverage often emphasizes and hypes certain aspects of high profile health debates. We hypothesized that in Canadian media coverage of access to healthcare issues about therapies and technologies including for rare diseases, the media would be largely sympathetic towards patients, thus adding to public debate that largely favors increased access to healthcare-even in the face of equivocal evidence regarding efficacy. In order to test this hypothesis, we conducted a content analysis of 530 news articles about access to health therapies and technologies from 15 major Canadian newspapers over a 10-year period. Articles were analyzed for the perspectives presented in the articles and the types of reasons or arguments presented either for or against the particular access issue portrayed in the news articles. We found that news media coverage was largely sympathetic towards increasing healthcare funding and ease of access to healthcare (77.4 %). Rare diseases and orphan drugs were the most common issues raised (22.6 %). Patients perspectives were often highlighted in articles (42.3 %). 96.8 % of articles discussed why access to healthcare needs to increase, and discussion that questioned increased access was only included in 33.6 % articles. We found that news media favors a patient access ethos, which may contribute to a difficult policy-making environment.

1990-01-01

MITRE Corporation's, A Review of Space Station Freedom Program Capabilities for the Development and Application of Advanced Automation, cites as a critical issue the following situation, extant at the NASA facilities visited in the course of preparing the review: The major issues noted with regard to design and research facilities deal with cooperative problem solving, technology transfer, and communication between these facilities. While the authors were visiting lab and test beds to collect information, personnel at many of these facilities were interested in any information they could collect on activities at other facilities. A formal means of gathering this information could not be identified by these personnel. While communication between some facilities was taking place or was planned, for technology transfer or coordination of schedules (e.g., for SADP demonstrations), poor communication between these facilities could lead to a lack of technical standards, duplication of effort, poorly defined interfaces, scheduling problems, and increased cost. Formal mechanisms by which effective communication and cooperative problem solving can take place, and information can be disseminated, must be defined. A solution is proposed for the communications aspects of the issues addressed above; and offered at the same time a solution which can prove effective in dealing with some of the problems being encountered with expertise being lost via retirement or defection to the private sector. The proffered recommendations are recognizably cost-effective and tap the rising sector of expert knowledge being produced by the American academic community.

Background With advances in computer technologies, Web-based interventions are widely accepted and welcomed by health care providers and researchers. Although the benefits of Web-based interventions on physical activity promotion have been documented, the programs have rarely targeted Asian Americans, including Asian American midlife women. Subsequently, culturally competent Web-based physical activity programs for Asian Americans may be necessary. Objective The purpose of our study was to explore practical issues in developing and implementing a culturally competent Web-based physical activity promotion program for 2 groups of Asian American women—Chinese American and Korean American midlife women—and to provide implications for future research. Methods While conducting the study, the research team members wrote individual memos on issues and their inferences on plausible reasons for the issues. The team had group discussions each week and kept the minutes of the discussions. Then, the memos and minutes were analyzed using a content analysis method. Results We identified practical issues in 4 major idea categories: (1) bilingual translators’ language orientations, (2) cultural sensitivity requirement, (3) low response rate, interest, and retention, and (4) issues in implementation logistics. Conclusions Based on the issues, we make several suggestions for the use of bilingual translators, motivational strategies, and implementation logistics. PMID:27872035

Daneault, Jean-Francois

2018-01-01

Essential tremor (ET) is the most common movement disorder. Individuals exhibit postural and kinetic tremor that worsens over time and patients may also exhibit other motor and non-motor symptoms. While millions of people are affected by this disorder worldwide, several barriers impede an optimal clinical management of symptoms. In this paper, we discuss the impact of ET on patients and review major issues to the optimal management of ET; from the side-effects and limited efficacy of current medical treatments to the limited number of people who seek treatment for their tremor. Then, we propose seven different areas within which mobile and wearable technology may improve the clinical management of ET and review the current state of research in these areas. PMID:29725318

Approaches to the identification of new nonhormonal targets for male contraception.

Kopf, Gregory S

2008-10-01

Fertility control is a global health issue with major personal and societal impact. Although, currently, there are several different options for contraception, the technologies behind these are antiquated, and the options for male-based contraception (i.e., withdrawal, condom and vasectomy) are inadequate. The genomic, proteomic and bioinformatic revolutions have provided new tools and new targets for contraceptive development, and the results of such approaches have identified gene products that play critical roles in male reproduction, thus expanding the array of potential targets for novel and innovative male-based contraceptives. This article will review the types of targets being considered in the development of nonhormonal male contraceptives and the technologies used to identify and validate these targets.

2017-12-01

The paper addresses the issues of solving complex problems that require using supercomputers or multiprocessor clusters available for most researchers nowadays. Efficient distribution of high performance computing resources according to actual application needs has been a major research topic since high-performance computing (HPC) technologies became widely introduced. At the same time, comfortable and transparent access to these resources was a key user requirement. In this paper we discuss approaches to build a virtual private supercomputer available at user's desktop: a virtual computing environment tailored specifically for a target user with a particular target application. We describe and evaluate possibilities to create the virtual supercomputer based on light-weight virtualization technologies, and analyze the efficiency of our approach compared to traditional methods of HPC resource management.

The National Aeronautics and Space Administration (NASA) is a major user of liquid hydrogen. In particular, NASA's John F. Kennedy (KSC) Space Center has operated facilities for handling and storing very large quantities of liquid hydrogen (LH2) since the early 1960s. Safe operations pose unique challenges and as a result NASA has invested in technology development to improve operational efficiency and safety. This paper reviews recent innovations including methods of leak and fire detection and aspects of large storage tank health and integrity. We also discuss the use of liquid hydrogen in space and issues we are addressing to ensure safe and efficient operations should hydrogen be used as a propellant derived from in-situ volatiles.

Coordinating and controlling large numbers of autonomous or semi-autonomous robot elements in a space construction activity will present problems that are very different from most command and control problems encountered in the space business. As part of our research into the feasibility of robot constructors in space, the CSC Operations Group is examining a variety of command, control, and communications (C3) issues. Two major questions being asked are: can we apply C3 techniques and technologies already developed for use in space; and are there suitable terrestrial solutions for extraterrestrial C3 problems? An overview of the control architectures, command strategies, and communications technologies that we are examining is provided and plans for simulations and demonstrations of our concepts are described.

Small and medium enterprises (SMEs) are often the main pillar of an economy. Minor accidents, ergonomics problems, old and outdated machinery, and lack of awareness have created a need for implementation of safety practices in SMEs. Implementation of healthy working conditions creates positive impacts on economic and social development. In this study, a questionnaire was developed and administered to 30 randomly chosen SMEs in and around Mumbai, Maharashtra, and other states in India to evaluate safety practices implemented in their facilities. The study also looked into the barriers and drivers for technology innovation and suggestions were also received from the respondent SMEs for best practices on safety issues. In some SMEs, risks associated with safety issues were increased whereas risks were decreased in others. Safety management practices are inadequate in most SMEs. Market competitiveness, better efficiency, less risk, and stringent laws were found to be most significant drivers; and financial constraints, lack of awareness, resistance to change, and lack of training for employees were found to be main barriers. Competition between SMEs was found to be major reason for implementation of safety practices in the SMEs. The major contribution of the study has been awareness building on safety issues in the SMEs that participated in the project.

A Practical Approach to Starting Fission Surface Power Development

NASA Technical Reports Server (NTRS)

Mason, Lee S.

2006-01-01

The Prometheus Power and Propulsion Program has been reformulated to address NASA needs relative to lunar and Mars exploration. Emphasis has switched from the Jupiter Icy Moons Orbiter (JIMO) flight system development to more generalized technology development addressing Fission Surface Power (FSP) and Nuclear Thermal Propulsion (NTP). Current NASA budget priorities and the deferred mission need date for nuclear systems prohibit a fully funded reactor Flight Development Program. However, a modestly funded Advanced Technology Program can and should be conducted to reduce the risk and cost of future flight systems. A potential roadmap for FSP technology development leading to possible flight applications could include three elements: 1) Conceptual Design Studies, 2) Advanced Component Technology, and 3) Non-Nuclear System Testing. The Conceptual Design Studies would expand on recent NASA and DOE analyses while increasing the depth of study in areas of greatest uncertainty such as reactor integration and human-rated shielding. The Advanced Component Technology element would address the major technology risks through development and testing of reactor fuels, structural materials, primary loop components, shielding, power conversion, heat rejection, and power management and distribution (PMAD). The Non-Nuclear System Testing would provide a modular, technology testbed to investigate and resolve system integration issues.

NASA's advanced life support technologies are being combined with Arctic science and engineering knowledge in the Advanced Life Systems for Extreme Environments (ALSEE) project. This project addresses treatment and reduction of waste, purification and recycling of water, and production of food in remote communities of Alaska. The project focus is a major issue in the state of Alaska and other areas of the Circumpolar North; the health and welfare of people, their lives and the subsistence lifestyle in remote communities, care for the environment, and economic opportunity through technology transfer. The challenge is to implement the technologies in a manner compatible with the social and economic structures of native communities, the state, and the commercial sector. NASA goals are technology selection, system design and methods development of regenerative life support systems for planetary and Lunar bases and other space exploration missions. The ALSEE project will provide similar advanced technologies to address the multiple problems facing the remote communities of Alaska and provide an extreme environment testbed for future space applications. These technologies have never been assembled for this purpose. They offer an integrated approach to solving pressing problems in remote communities.

Horse meat and its products can be considered as a food with a high nutritional value. However, due to cases of economically motivated food adulteration by the intentional addition of horse meat beef products in recent years, horse meat has become a controversial issue. Consumer confidence in meat products and the meat industry has diminished, although consumers consider the differences between the food content and the label as the major issue rather than the safety and nutritional characteristics of horse meat. The elaboration of meat products from horse meat (e.g. "cecina", dry-cured loin, salami, bressaola and pâté) is also an interesting alternative to other traditional meat products such as dry-cured pork hams, pork sausages and liver pâtés. In this review, the technological aspects, safety and storage stability of meat products elaborated from horse meat will be addressed by highlighting the nutritional and sensory aspects of these meat products. We aim to improve the existing knowledge about horse meat in the view of recent scandals. Copyright © 2017 Elsevier Ltd. All rights reserved.

Recycling of polymers: a review.

Plastics are inexpensive, easy to mold, and lightweight. These and many other advantages make them very promising candidates for commercial applications. In many areas, they have substantially suppressed traditional materials. However, the problem of recycling still is a major challenge. There are both technological and economic issues that restrain the progress in this field. Herein, a state-of-art overview of recycling is provided together with an outlook for the future by using popular polymers such as polyolefins, poly(vinyl chloride), polyurethane, and poly(ethylene terephthalate) as examples. Different types of recycling, primary, secondary, tertiary, quaternary, and biological recycling, are discussed together with related issues, such as compatibilization and cross-linking. There are various projects in the European Union on research and application of these recycling approaches; selected examples are provided in this article. Their progress is mirrored by granted patents, most of which have a very limited scope and narrowly cover certain technologies. Global introduction of waste utilization techniques to the polymer market is currently not fully developed, but has an enormous potential. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Introduction for the special issue on recent advances in drug delivery across tissue barriers.

Mrsny, Randall J; Brayden, David J

2016-01-01

This special issue of Tissue Barriers contains a series of reviews with the common theme of how biological barriers established at epithelial tissues limit the uptake of macromolecular therapeutics. By improving our functional understanding of these barriers, the majority of the authors have highlighted potential strategies that might be applied to the non-invasive delivery of biopharmaceuticals that would otherwise require an injection format for administration. Half of the articles focus on the potential of particular technologies to assist oral delivery of peptides, proteins and other macromolecules. These include use of prodrug chemistry to improve molecule stability and permeability, and the related potential for oral delivery of poorly permeable agents by cell-penetrating peptides and dendrimers. Safety aspects of intestinal permeation enhancers are discussed, along with the more recent foray into drug-device combinations as represented by intestinal microneedles and externally-applied ultrasound. Other articles highlight the crossover between food research and oral delivery based on nanoparticle technology, while the final one provides a fascinating interpretation of the physiological problems associated with subcutaneous insulin delivery and how inefficient it is at targeting the liver.

A proton medical accelerator by the SBIR route — an example of technology transfer

NASA Astrophysics Data System (ADS)

Martin, R. L.

1989-04-01

Medical facilities for radiation treatment of cancer with protons have been established in many laboratories throughout the world. Essentially all of these have been designed as physics facilities, however, because of the requirement for protons up to 250 MeV. Most of the experience in this branch of accelerator technology lies in the national laboratories and a few large universities. A major issue is the transfer of this technology to the commercial sector to provide hospitals with simple, reliable and relatively inexpensive accelerators for this application. The author has chosen the SBIR route to accomplish this goal. ACCTEK Associates has received grants from the National Cancer Institute for development of the medical accelerator and beam delivery systems. Considerable encouragement and help has been received from Argonne National Laboratory and the Department of Energy. The experiences to date and the pros and cons on this approach to commercializing medical accelerators are described.

Radio Frequency Identification (RFID) technology not only offers tracking capability to locate equipment, supplies and people in real time, but also provides efficient and accurate access to medical data for health professionals. However, the reality of RFID adoption in healthcare is far behind earlier expectation. This study reviews literature on the use of RFID in healthcare/hospitals following a formal innovation-decision framework. We aim to identify the common applications, potential benefits, barriers, and critical success factors. Our study facilitates quick assessment and provides guidance for researchers and practitioners in adopting RFID in medical arenas. Many earlier adopters in healthcare found RFID to be functional and useful in such areas as asset tracking and patient identification. Major barriers to adoption include technological limitations, interference concerns, prohibitive costs, lack of global standards and privacy concerns. Better designed RFID systems with low cost and privacy issues addressed are needed to increase acceptance of RFID in healthcare.

Recent developments in implantable cardioverter-defibrillators (ICDs) and smartphone technology have increased the possibilities for remote monitoring. It is the purpose of this review to give an overview of these new possibilities. Remote monitoring in ICD allows for early detection of lead fractures and remote follow-up of patients. Possible limitations are the lack of standardization and the possible unsafety of the data stored on the ICD. Secondly, remote monitoring of health parameters using smartphone compatible wearables and smartphone medical apps is addressed. Possible limitations include the fact that the majority of smartphone apps are unregulated by the regulatory authorities and privacy issues such as selling of app-generated data to third parties. Lastly, clinical studies with smartphone apps are discussed. Expert commentary: New technologies in ICDs and smartphones have the potential to be used for remote monitoring. However, unreliability of smartphone technology, inadequate legislation and lack of reimbursement impede implementation.

We are proud to introduce the project, INDO-NORDEN, funded in response to the Science and Technology call of the INNO INDIGO Partnership Program (IPP) on Biobased Energy. The project is scheduled to begin from April 2017. The proposed project aims to address both subtopics of the call, Biofuels and From Waste to Energy with research partners from Finland (coordinating unit), India and Estonia. The EU and India share common objectives in enhancing energy security, promoting energy efficiency and energy safety, and the pursuit of sustainable development of clean and renewable energy source. The main objective of INDO-NORDEN is to investigate, evaluate and develop efficient processes and land use practices of transforming forest and agricultural biomass, agricultural residues and farm waste into clean fuels (solid, liquid or gas), by thermochemical or biochemical conversions. Forestry and agriculture are the major bioenergy sectors in Finland. Intensive forest harvesting techniques are being used in Finland to enhance the share of bioenergy in the total energy consumption in the future. However, there are no clear indications how environmentally safe are these intensive forestry practices in Finland. We address this issue through field studies addressing the climate impacts on the ecosystem carbon balance and detailed life cycle assessment. The role of agriculture in Finland is expected to grow significantly in the years to come. Here, we follow a holistic field experimental approach addressing several major issues relevant to Nordic agriculture under changing climatic conditions - soil nutrient management, recycling of nutrients, farm and agricultural waste management, biogas production potentials, greenhouse gas inventorying and entire production chain analysis. There is a considerable potential for process integration in the biofuel sector. This project plans to develop biofuel production processes adopted in Estonia and India with a major aim of enhancing biofuel yields. Additionally, the effects of biomass raw material on ash characteristics and behavior as well as on the fine particle and gas emissions in biomass-fired combustion plants will be evaluated. Thus, the project goes an extra mile in addressing both technological and environmental effects of bioenergy production with combustion processes. Finally, with a voluntary participation of companies with excellent track record in biogas production and CHP technology in participating countries, the project aims to bridge the gap between science, technology and industries.

Higher-Order Theory for Functionally Graded Materials

NASA Technical Reports Server (NTRS)

Aboudi, Jacob; Pindera, Marek-Jerzy; Arnold, Steven M.

1999-01-01

This paper presents the full generalization of the Cartesian coordinate-based higher-order theory for functionally graded materials developed by the authors during the past several years. This theory circumvents the problematic use of the standard micromechanical approach, based on the concept of a representative volume element, commonly employed in the analysis of functionally graded composites by explicitly coupling the local (microstructural) and global (macrostructural) responses. The theoretical framework is based on volumetric averaging of the various field quantities, together with imposition of boundary and interfacial conditions in an average sense between the subvolumes used to characterize the composite's functionally graded microstructure. The generalization outlined herein involves extension of the theoretical framework to enable the analysis of materials characterized by spatially variable microstructures in three directions. Specialization of the generalized theoretical framework to previously published versions of the higher-order theory for materials functionally graded in one and two directions is demonstrated. In the applications part of the paper we summarize the major findings obtained with the one-directional and two-directional versions of the higher-order theory. The results illustrate both the fundamental issues related to the influence of microstructure on microscopic and macroscopic quantities governing the response of composites and the technologically important applications. A major issue addressed herein is the applicability of the classical homogenization schemes in the analysis of functionally graded materials. The technologically important applications illustrate the utility of functionally graded microstructures in tailoring the response of structural components in a variety of applications involving uniform and gradient thermomechanical loading.

Over the past century technology has played a decisive role in defining, driving, and reinventing procedures, devices, and pharmaceuticals in healthcare. Cloud computing has been introduced only recently but is already one of the major topics of discussion in research and clinical settings. The provision of extensive, easily accessible, and reconfigurable resources such as virtual systems, platforms, and applications with low service cost has caught the attention of many researchers and clinicians. Healthcare researchers are moving their efforts to the cloud, because they need adequate resources to process, store, exchange, and use large quantities of medical data. This Vision 20/20 paper addresses major questions related to the applicability of advanced cloud computing in medical imaging. The paper also considers security and ethical issues that accompany cloud computing.

Along with the international trends in history of computing, Dutch contributions over the past twenty years moved away from a focus on machinery to the broader scope of use of computers, appropriation of computing technologies in various traditions, labour relations and professionalisation issues, and, lately, software. It is only natural that an emerging field like computer science sets out to write its genealogy and canonise the important steps in its intellectual endeavour. It is fair to say that a historiography diverging from such "home" interest, started in 1987 with the work of Eda Kranakis--then active in The Netherlands--commissioned by the national bureau for technology assessment, and Gerard Alberts, turning a commemorative volume of the Mathematical Center into a history of the same institute. History of computing in The Netherlands made a major leap in the spring of 1994 when Dirk de Wit, Jan van den Ende and Ellen van Oost defended their dissertations, on the roads towards adoption of computing technology in banking, in science and engineering, and on the gender aspect in computing. Here, history of computing had already moved from machines to the use of computers. The three authors joined Gerard Alberts and Onno de Wit in preparing a volume on the rise of IT in The Netherlands, the sequel of which in now in preparation in a team lead by Adrienne van den Bogaard. Dutch research reflected the international attention for professionalisation issues (Ensmenger, Haigh) very early on in the dissertation by Ruud van Dael, Something to do with computers (2001) revealing how occupations dealing with computers typically escape the pattern of closure by professionalisation as expected by the, thus outdated, sociology of professions. History of computing not only takes use and users into consideration, but finally, as one may say, confronts the technological side of putting the machine to use, software, head on. The groundbreaking works of the 2000 Paderborn meeting and by Martin Campbell-Kelly resonate in work done in The Netherlands and recently in a major research project sponsored by the European Science Foundation: Software for Europe. The four contributions to this issue offer a true cross-section of ongoing history of computing in The Netherlands. Gerard Alberts and Huub de Beer return to the earliest computers at the Mathematical Center. As they do so under the perspective of using the machines, the result is, let us say, remarkable. Adrienne van den Bogaard compares the styles of software as practiced by Van der Poel and Dijkstra: so much had these two pioneers in common, so different the consequences they took. Frank Veraart treats us with an excerpt from his recent dissertation on the domestication of the micro computer technology: appropriation of computing technology is shown by the role of intermediate actors. Onno de Wit, finally, gives an account of the development, prior to internet, of a national data communication network among large scale users and its remarkable persistence under competition with new network technologies.

Decision Making Under Uncertainty and Complexity: A Model-Based Scenario Approach to Supporting Integrated Water Resources Management

Liu, Y.; Gupta, H.; Wagener, T.; Stewart, S.; Mahmoud, M.; Hartmann, H.; Springer, E.

2007-12-01

Some of the most challenging issues facing contemporary water resources management are those typified by complex coupled human-environmental systems with poorly characterized uncertainties. In other words, major decisions regarding water resources have to be made in the face of substantial uncertainty and complexity. It has been suggested that integrated models can be used to coherently assemble information from a broad set of domains, and can therefore serve as an effective means for tackling the complexity of environmental systems. Further, well-conceived scenarios can effectively inform decision making, particularly when high complexity and poorly characterized uncertainties make the problem intractable via traditional uncertainty analysis methods. This presentation discusses the integrated modeling framework adopted by SAHRA, an NSF Science & Technology Center, to investigate stakeholder-driven water sustainability issues within the semi-arid southwestern US. The multi-disciplinary, multi-resolution modeling framework incorporates a formal scenario approach to analyze the impacts of plausible (albeit uncertain) alternative futures to support adaptive management of water resources systems. Some of the major challenges involved in, and lessons learned from, this effort will be discussed.

Maulden, Sarah A

2003-05-01

This review addresses the impact of information technology and the Internet on the current and future practice of neurology. Information technology is influencing medical practice in ways that could be both beneficial and harmful. Scenarios are presented to depict some of the ways in which the practice of neurology is being influenced by the growth of technology. First, the advantages and disadvantages of e-mail as a means of doctor-patient communication are presented. Some of the ethical and legal issues arising in this context are discussed.Second, the Internet is changing neurologists' relationships to other professionals in the health care industry. Geographical isolation is less problematic than in the past. Telemedicine, including remote consulting via the Web, has special implications for neurologists in several areas, including stroke management, movement disorders, and epilepsy.Third, the growing availability of large databases, powerful search engines, and online full-text journals is discussed. Skill in navigating and managing these resources will become increasingly important. New computer-assisted decision support systems will continue to be implemented. Applications exist or are being developed for use by clinicians for many specific neurologic disorders.Finally, some of the problematic issues concerning medical use of the Internet are discussed, including availability, portability, security, quality, and outcomes. Medical information systems, with their attendant advantages and limitations, will become increasingly significant in the practice of neurology. Despite overall improvement in access to information, major barriers still exist to the proper implementation and utilization of truly integrated information systems.

Greenhouse gas accounting and waste management.

PubMed

Gentil, Emmanuel; Christensen, Thomas H; Aoustin, Emmanuelle

2009-11-01

Accounting of emissions of greenhouse gas (GHG) is a major focus within waste management. This paper analyses and compares the four main types of GHG accounting in waste management including their special features and approaches: the national accounting, with reference to the Intergovernmental Panel on Climate Change (IPCC), the corporate level, as part of the annual reporting on environmental issues and social responsibility, life-cycle assessment (LCA), as an environmental basis for assessing waste management systems and technologies, and finally, the carbon trading methodology, and more specifically, the clean development mechanism (CDM) methodology, introduced to support cost-effective reduction in GHG emissions. These types of GHG accounting, in principle, have a common starting point in technical data on GHG emissions from specific waste technologies and plants, but the limited availability of data and, moreover, the different scopes of the accounting lead to many ways of quantifying emissions and producing the accounts. The importance of transparency in GHG accounting is emphasised regarding waste type, waste composition, time period considered, GHGs included, global warming potential (GWP) assigned to the GHGs, counting of biogenic carbon dioxide, choice of system boundaries, interactions with the energy system, and generic emissions factors. In order to enhance transparency and consistency, a format called the upstream-operating-downstream framework (UOD) is proposed for reporting basic technology-related data regarding GHG issues including a clear distinction between direct emissions from waste management technologies, indirect upstream (use of energy and materials) and indirect downstream (production of energy, delivery of secondary materials) activities.

Origins of medical innovation: the case of coronary artery stents.

PubMed

Xu, Shuai; Avorn, Jerry; Kesselheim, Aaron S

2012-11-01

Innovative medical devices make major contributions to patient welfare, and coronary stents have been among the most important device developments of recent decades. However, the origins of such breakthrough medical technologies remain poorly understood. Using a comprehensive database of patents, we identified all individuals and institutions that developed intellectual property related to stent technology early in its development process. The patents were categorized and described using a predetermined qualitative coding strategy. We found 245 granted patents related to bare metal coronary artery stents from 1984 (when the first patent issued in this field) to 1994 (after the first stents were approved). Each year showed an increase in the number of patent filings: from 1 in 1984 to 97 in 1994. The largest fraction of patents was issued to private entities (44.9% of the total). Public companies, individual inventors, and nonprofit institutions represented 31.4%, 18.0%, and 5.7%, respectively. The top 10 most-cited patents in the field were dominated by 2 private entities, Expandable Grafts Partnership and Cook Inc, organizations created by or dependent on the work of independent academic physician-inventors. Coronary artery stent technology first arose from individual physician-inventors within academic medical centers and their associated private companies. After these initial innovations were in place, the field became dominated by large public companies. This history suggests that policies aimed at encouraging transformative medical device development would have their greatest effect if focused on individual inventors and scientists performing the early stages of technology development.

Dryland ecohydrology and climate change: critical issues and technical advances

NASA Astrophysics Data System (ADS)

Wang, L.; D'Odorico, P.; Evans, J. P.; Eldridge, D.; McCabe, M. F.; Caylor, K. K.; King, E. G.

2012-04-01

Drylands cover about 40% of the terrestrial land surface and account for approximately 40% of global net primary productivity. Water is fundamental to the biophysical processes that sustain ecosystem function and food production, particularly in drylands, where a tight coupling exists between water resource availability and ecosystem productivity, surface energy balance, and biogeochemical cycles. Currently, drylands support at least 2 billion people and comprise both natural and managed ecosystems. In this synthesis, we identify some current critical issues in the understanding of dryland systems and discuss how arid and semiarid environments are responding to the changes in climate and land use. Specifically, we focus on dryland agriculture and food security, dryland population growth, desertification, shrub encroachment and dryland development issues as factors of change requiring increased understanding and management. We also review recent technical advances in the quantitative assessment of human versus climate change related drivers of desertification, evapotranspiration partitioning using field deployable stable water isotope systems and the remote sensing of key ecohydrological processes. These technological advances provide new tools that assist in addressing major critical issues in dryland ecohydrology under climate change

Advanced data management design for autonomous telerobotic systems in space using spaceborne symbolic processors

NASA Technical Reports Server (NTRS)

Goforth, Andre

1987-01-01

The use of computers in autonomous telerobots is reaching the point where advanced distributed processing concepts and techniques are needed to support the functioning of Space Station era telerobotic systems. Three major issues that have impact on the design of data management functions in a telerobot are covered. It also presents a design concept that incorporates an intelligent systems manager (ISM) running on a spaceborne symbolic processor (SSP), to address these issues. The first issue is the support of a system-wide control architecture or control philosophy. Salient features of two candidates are presented that impose constraints on data management design. The second issue is the role of data management in terms of system integration. This referes to providing shared or coordinated data processing and storage resources to a variety of telerobotic components such as vision, mechanical sensing, real-time coordinated multiple limb and end effector control, and planning and reasoning. The third issue is hardware that supports symbolic processing in conjunction with standard data I/O and numeric processing. A SSP that currently is seen to be technologically feasible and is being developed is described and used as a baseline in the design concept.

Since the early 1990s with the arrival of a variety of new technologies, the capacity for authentic astronomical research at the high school level has skyrocketed. This potential, however, has not realised the bright-eyed hopes and dreams of the early pioneers who expected to revolutionise science education through the use of telescopes and other astronomical instrumentation in the classroom. In this paper, a general history and analysis of these attempts is presented. We define what we classify as an Astronomy Research in the Classroom (ARiC) project and note the major dimensions on which these projects differ before describing the 22 major student research projects active since the early 1990s. This is followed by a discussion of the major issues identified that affected the success of these projects and provide suggestions for similar attempts in the future.

The past decade has seen increased international recognition of the importance of the services provided by natural ecosystems. It is unclear however whether such international awareness will lead to improved environmental management in many regions. We explore this issue by examining the specific case of fish migration and dams on the Mekong river. We determine that dams on the Mekong mainstem and major tributaries will have a major impact on the basin's fisheries and the people who depend upon them for food and income. We find no evidence that current moves towards dam construction will stop, and consider two scenarios for the future of the fisheries and other ecosystems of the basin. We conclude that major investment is required in innovative technology to reduce the loss of ecosystem services, and alternative livelihood strategies to cope with the losses that do occur.

Technology issues for high-speed civil transports

Dollyhigh, Samuel M.

1989-01-01

Current efforts to prepare the technology for a new generation of high-speed civil transports are focused primarily on environmental issues. This paper reports on studies to provide: (1) acceptable engine emissions; (2) reduced airport/community noise; and (3) sonic-boom minimization. Attention is also given to technologies that allow a lighter, more efficient vehicle and to other high-payoff technologies, such as supersonic laminar flow; these have the potential for yielding not only better mission performance but also enhanced environmental compatibility for these new vehicles. The technology issues are reviewed in terms of the technologies themselves and their impact on the equally crucial need for economic success.

Carrington, Connie K.; Feingold, Harvey; Howell, Joe T. (Technical Monitor)

2002-01-01

The availability of abundant, affordable power where needed is a key to the future exploration and development of space as well as future sources of clean terrestrial power. One innovative approach to providing such power is the use of wireless power transmission (WPT). There are at least two possible WPT methods that appear feasible; microwave and laser. Microwave concepts have been generated, analyzed and demonstrated. Technologies required to provide an end-to-end system have been identified and roadmaps generated to guide technology development requirements. Recently, laser W T approaches have gained an increased interest. These approaches appear to be very promising and will possibly solve some of the major challenges that exist with the microwave option. Therefore, emphasis is currently being placed on the laser WPT activity. This paper will discuss the technology requirements, technology roadmaps and technology flight experiments demonstrations required to lead toward a pilot plant demonstration. Concepts will be discussed along with the modeling techniques that are used in developing them. Feasibility will be addressed along with the technology needs, issues and capabilities for particular concepts. Flight experiments and demonstrations will be identified that will pave the road from demonstrations to pilot plants and beyond.

Forecasting the impact of virtual environment technology on maintenance training

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

1993-01-01

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.

Adapting sustainable low-carbon techologies to reduce carbon dioxide emissions from coal-fired power plants in China

NASA Astrophysics Data System (ADS)

Kuo, Peter Shyr-Jye

1997-09-01

The scientific community is deeply concerned about the effect of greenhouse-gases (GHGs) on global climate change. A major climate shift can result in tragic destruction to our world. Carbon dioxide (COsb2) emissions from coal-fired power plants are major anthropogenic sources that contribute to potential global warming. The People's Republic of China, with its rapidly growing economy and heavy dependence on coal-fired power plants for electricity, faces increasingly serious environmental challenges. This research project seeks to develop viable methodologies for reducing the potential global warming effects and serious air pollution arising from excessive coal burning. China serves as a case study for this research project. Major resolution strategies are developed through intensive literature reviews to identify sustainable technologies that can minimize adverse environmental impacts while meeting China's economic needs. The research thereby contributes technological knowledge to the field of Applied Sciences. The research also integrates modern power generation technologies with China's current and future energy requirements. With these objectives in mind, this project examines how China's environmental issues are related to China's power generation methods. This study then makes strategic recommendations that emphasize low-carbon technologies as sustainable energy generating options to be implemented in China. These low-carbon technologies consist of three options: (1) using cleaner fuels converted from China's plentiful domestic coal resources; (2) applying high-efficiency gas turbine systems for power generation; and (3) integrating coal gasification processes with energy saving combined cycle gas turbine systems. Each method can perform independently, but a combined strategy can achieve the greatest COsb2 reductions. To minimize economic impacts caused by technological changes, this study also addresses additional alternatives that can be implemented in parallel with the proposed technologies. Principal options include promoting wind, solar and biogas as alternative energies; encouraging reforestation; using economic incentives to change energy policies; and gradually replacing obsolete facilities with new power plants. This study finds that the limited capacity and associated costs of alternative energies are the main factors that prevent competition with coal-based energy in China today.

2018-06-15

The wide-spread prevalence of unimproved sanitation technologies has been a major cause of concern for the environment and public health, and China is no exception to this. Towards the sanitation issue, toilet revolution has become a buzzword in China recently. This paper elaborates the backgrounds, connotations, and actions of the toilet revolution in China. The toilet revolution aims to create sanitation infrastructure and public services that work for everyone and that turn waste into value. Opportunities for implementing the toilet revolution include: fulfilling Millennium Development Goals and new Sustainable Development Goals; government support at all levels for popularizing sanitary toilet; environmental protection to alleviate wastewater pollution; resource recovery from human waste and disease prevention for health and wellbeing improvement. Meanwhile, the challenges faced are: insufficient funding and policy support, regional imbalance and lagging approval processes, weak sanitary awareness and low acceptance of new toilets, lack of R&D and service system. The toilet revolution requires a concerted effort from many governmental departments. It needs to address not only technology implementation, but also social acceptance, economic affordability, maintenance issues and, increasingly, gender considerations. Aligned with the ecological sanitation principles, it calls for understanding issues across the entire sanitation service chain. Public-private partnership is also recommended to absorb private capital to make up the lack of funds, as well as arouse the enthusiasm of the public. Copyright © 2017 The Authors.

The face of health care is changing as new technologies are being incorporated into the existing infrastructure. Electronic patient records and sensor networks for in-home patient monitoring are at the current forefront of new technologies. Paper-based patient records are being put in electronic format enabling patients to access their records via the Internet. Remote patient monitoring is becoming more feasible as specialized sensors can be placed inside homes. The combination of these technologies will improve the quality of health care by making it more personalized and reducing costs and medical errors. While there are benefits to technologies, associated privacy and security issues need to be analyzed to make these systems socially acceptable. In this paper we explore the privacy and security implications of these next-generation health care technologies. We describe existing methods for handling issues as well as discussing which issues need further consideration.

We investigated issues that affect the use and adoption of telemedicine in Middle Eastern countries, taking the Hashemite Kingdom of Jordan and the Syrian Arab Republic as case studies. Our study is based on interviews with key stakeholders (including doctors, technicians, engineers, and decision makers) and questionnaires administered to key stakeholders (including patients), ensuring opinion was gained from people from a full range of backgrounds and roles in the healthcare system. We found doctor and patient resistance was a major issue preventing the adoption of telemedicine in both countries, followed by poor infrastructure, lack of funding, and lack of information technology training. Our research identifies that culture is a greater issue than technical matters for the adoption of telemedicine in Middle Eastern countries. Based on our preliminary results we developed a guideline framework for each country that might be applied to telemedicine projects at the pre-implementation phase. The proposed guideline framework was validated through a return visit to the stakeholders and seeking further opinion.

In the frame of the technology / demonstration activity for European launchers developments and evolutions, a top-down / bottom-up approach has been employed to identify promising technologies and alternative conception. The top-down approach consists in looking for system-driven design solutions and the bottom-up approach features design solutions leading to substantial advantages for the system. The main investigations have been devoted to structures, material and process technology.Preliminary specifications have been used in order to permit sub-system design with the goal to find the major benefit for the overall launch system. In this respect competitiveness factors have been defined to down- select the technology and the corresponding optimized design. The development cost, non-recurring cost, industrialization and operational aspects have been considered for the identification of the most interesting solutions. The TRL/IRL has been assessed depending on the manufacturing company and a preliminary development plan has been issued for some technology.The reference launch systems for the technology and demonstration programs are mainly Ariane 6 with its evolutions, VEGA C/E and others possible longer term systems. Requirements and reference structures architectures have been considered in order to state requirements for representative subscale or full scale demonstrators. The major sub-systems and structures analyzed are for instance the upper stage structures, the engine thrust frame (ETF), the inter stage structures (ISS), the cryogenic propellant tanks, the feeding lines and their attachments, the pressurization systems, the payload adapters and fairings. A specific analysis has been devoted to the efficiency of production processes associated to technologies and design features.The paper provides an overview of the main results of the technology and demonstration activities with the associated system benefits. The materials used for the main structures are metallic and composite owing to sub-systems or sub-assemblies proposed for the European launch systems in development and their evolutions.

The past decade, extensive efforts have been invested in understanding the nano-scale and revealing the capabilities offered by nanotechnology products to structural materials. Nevertheless, a major issue faced lately more seriously due to the interest of industry is on how to incorporate these nano-species into the final composite structure through existing manufacturing processes and infrastructure. In this work, we present the experience obtained from the latest nanotechnology research activities supported by ESA. The paper focuses on prepreg composite manufacturing technology and addresses:- Approaches for nano-enabling of composites- Up-scaling strategies towards final structures- Latest results on performance of nano-enabledfiber reinforced compositesSeveral approaches for the utilization of nanotechnology products in structural composite structures have been proposed and are reviewed, in short along with respective achieved results. A variety of nano-fillers has been proposed and employed, individually or in combination in hybrid forms, to approach the desired performance. A major part of the work deals with the up-scaling routes of these technologies to reach final products and industrial scales and processes while meeting end-user performance.

Biomimetics in Tribology

NASA Astrophysics Data System (ADS)

Gebeshuber, I. C.; Majlis, B. Y.; Stachelberger, H.

Science currently goes through a major change. Biology is evolving as new Leitwissenschaft, with more and more causation and natural laws being uncovered. The term `technoscience' denotes the field where science and technology are inseparably interconnected, the trend goes from papers to patents, and the scientific `search for truth' is increasingly replaced by search for applications with a potential economic value. Biomimetics, i.e. knowledge transfer from biology to technology, is a field that has the potential to drive major technical advances. The biomimetic approach might change the research landscape and the engineering culture dramatically, by the blending of disciplines. It might substantially support successful mastering of current tribological challenges: friction, adhesion, lubrication and wear in devices and systems from the meter to the nanometer scale. A highly successful method in biomimectics, the biomimicry innovation method, is applied in this chapter to identify nature's best practices regarding two key issues in tribology: maintenance of the physical integrity of a system, and permanent as well as temporary attachment. The best practices identified comprise highly diverse organisms and processes and are presented in a number of tables with detailed references.

Media can affect public views and opinions on science, policy and risk issues. This is especially true of a controversial emerging technology that is relatively unknown. The study presented here employs a media content analysis of carbon capture and storage (CCS), one potential strategy to reduce greenhouse gas emissions. The authors analyzed all mentions of CCS in two leading Canadian national newspapers and two major western regional newspapers from the first article that discussed CCS in 2004 to the end of 2009 (825 articles). An in-depth content analysis was conducted to examine factors relating to risk from CCS, how the technology was portrayed and if coverage was negatively or positively biased. We conclude by discussing the possible impact of media coverage on support or opposition to CCS adoption.

Wright, Caroline F; FitzPatrick, David R; Firth, Helen V

2018-05-01

The majority of rare diseases affect children, most of whom have an underlying genetic cause for their condition. However, making a molecular diagnosis with current technologies and knowledge is often still a challenge. Paediatric genomics is an immature but rapidly evolving field that tackles this issue by incorporating next-generation sequencing technologies, especially whole-exome sequencing and whole-genome sequencing, into research and clinical workflows. This complex multidisciplinary approach, coupled with the increasing availability of population genetic variation data, has already resulted in an increased discovery rate of causative genes and in improved diagnosis of rare paediatric disease. Importantly, for affected families, a better understanding of the genetic basis of rare disease translates to more accurate prognosis, management, surveillance and genetic advice; stimulates research into new therapies; and enables provision of better support.

An Analysis of the Impact of RFID Technology on Inventory Systems

NASA Astrophysics Data System (ADS)

Rekik, Yacine

Nowadays, most enterprises undertake large investments in order to implement information systems that support decision making for managing inventories. Nevertheless, if data collected from the physical processes used to feed these systems are not correct, there will be severe impacts on business performance. Inventory inaccuracy occurs when the inventory level in the Information System is not in agreement with the physically available inventory. In this chapter, we first describe the major factors generating inventory inaccuracy. Then, we provide situations permitting to manage an inventory system subject to errors. We provide a framework to model the inventory inaccuracy issue and focus on the impact of advanced identification systems, such as that provided by RFID technology, in improving the performance of a supply chain subject to inventory inaccuracies.

In the last decade, many proteomic technologies have been applied, with varying success, to the study of tissue samples of breast carcinoma for protein expression profiling in order to discover protein biomarkers/signatures suitable for: characterization and subtyping of tumors; early diagnosis, and both prognosis and prediction of outcome of chemotherapy. The purpose of this review is to critically appraise what has been achieved to date using proteomic technologies and to bring forward novel strategies - based on the analysis of clinically relevant samples - that promise to accelerate the translation of basic discoveries into the daily breast cancer clinical practice. In particular, we address major issues in experimental design by reviewing the strengths and weaknesses of current proteomic strategies in the context of the analysis of human breast tissue specimens.

Science and the city: A visual journey towards a critical place based science education

NASA Astrophysics Data System (ADS)

Ibrahim, Sheliza

The inclusion of societal and environmental considerations during the teaching and learning of science and technology has been a central focus among science educators for many decades. Major initiatives in science and technology curriculum advocate for science, technology, society and environment (STSE). Yet, it is surprising that despite these longstanding discussions, it is only recently that a handful of researchers have turned to students' 'places' (and the literature of place based education) to serve as a source of teaching and learning in science education. In my study, I explore three issues evident in place based science education. First, it seems that past scholarship focused on place-based projects which explore issues usually proposed by government initiatives, university affiliation, or community organizations. Second, some of the studies fail to pay extended attention to the collaborative and intergenerational agency that occurs between researcher, teacher, student, and community member dynamics, nor does it share the participatory action research process in order to understand how teacher practice, student learning, and researcher/local collaborations might help pedagogy emerge. The third issue is that past place-based projects, rarely if ever, return to the projects to remember the collaborative efforts and question what aspects sustained after they were complete. To address these issues, I propose a critical place based science education (CPBSE) model. I describe a participatory action research project that develops and explores the CPBSE model. The data were gathered collaboratively among teachers, researchers, and students over 3 years (2006-2008), via digital video ethnography, photographs, and written reflections. The data were analysed using a case study approach and the constant comparative method. I discuss the implications for its practice in the field of STSE and place based education. I conclude that an effective pedagogical model of CPBSE comprises of three stages: critical visualizing, investigating, remembering, by sharing Science and the City (a case study that connects science to place using visual imagery).

The author outlines what he considers to be the key environmental issues affecting Clean Coal Technology (CCT) deployment both in the US and internationally. Since the international issues are difficult to characterize given different environmental drivers in various countries and regions, the primary focus of his remarks is on US deployment. However, he makes some general remarks, particularly regarding the environmental issues in developing vs. developed countries and how these issues may affect CCT deployment. Further, how environment affects deployment depends on which particular type of clean coal technology one is addressing. It is not the author`s intention to mentionmore » many specific technologies other than to use them for the purposes of example. He generally categorizes CCTs into four groups since environment is likely to affect deployment for each category somewhat differently. These four categories are: Precombustion technologies such as coal cleaning; Combustion technologies such as low NOx burners; Postcombustion technologies such as FGD systems and postcombustion NOx control; and New generation technologies such as gasification and fluidized bed combustion.« less

Background: Growth in agricultural science and technology is deemed essential for in-creasing agricultural output; reduce the vulnerability of rural poverty and in turn, food security. Food security and growth in agricultural output depends on technological usages, which enhances the pro-ductive capacity of the agricultural sector. The indicators of food security utilised in this study in-clude: dietary energy supply, average value of food production, prevalence of food inadequacy, among others. Objective: In this paper, we examined the level of technology and how investment in the agriculture and technology can improve technical know-how in Nigeria with a view to achieving food security. Method: We carried out the analysis on how investment in technology and institutional framework can improve the level of food availability (a key component of food security) in Nigeria using econ-ometric technique based on Autoregressive Distribution Lag (ARDL) framework. Results: The results showed, inter alia, that in Nigeria, there is a high level of food insecurity as a result of low attention on food production occasioned by the pervasive influence of oil that become the major export product. Conclusion: It was noted that the availability of arable land was one of the major factors to increase food production to solve the challenge of food insecurity. Thus, the efforts of reducing the rate of food insecurity are essential in this regards. This can also be achieved, among others, by active interactions between government and farmers, to make contribution to important planning issues that relate to food production in the country and above all, social protection policies should be geared or channelled to agricultural sector to protect farmers who are vulnerable to shocks and avert risks associated with agriculture.

Long term storage of unprocessed biological wastes and human wastes can present major health issues and a loss of potential resources. Space vehicles and planetary habitats are typically resource-scarce or resource-limited environments for long-term human habitation. To-date, most of the resources will need to be supplied from Earth, but this may not be possible for long duration human exploration. Based on present knowledge, there is only very limited in-situ resources on planetary habitats. Hence, the opportunity to "live off the land" in a planetary habitat is limited. However, if we assume that wastes generated by human explorers are viewed as resources, there is great potential to utilize and recycle them, thereby reducing the requirements for supply Earth and enabling the "live off the land" exploration scenario. Technologies used for the recovery of resources from wastes should be reliable, safe, easy to operate, fail-proof, modular, automated and preferably multifunctional in being capable of handling mixed solid and liquid wastes. For a lunar habitat, energy does not appear to be the major driving factor amongst the technologies studied. Instead, reliability appears to be more important[1] . This paper reports studies to date on drying technologies to remove water from solid wastes and brines. Experimental performance data obtained for recovery water from wastes and brine are presented. Simplicity of operation of hardware and energy efficiency are discussed. Some improvements and modifications to hardware were performed. Hopefully, this information will assist in future efforts in the "downselection" of technologies for recovery of water and resources from solid wastes and brines.

Because of the unique networking characteristics of communications satellites, global satellite networks are moving to the forefront in enhancing national and global information infrastructures. Simultaneously, broadband data services, which are emerging as the major market driver for future satellite and terrestrial networks, are being widely acknowledged as the foundation for an efficient global information infrastructure. In the past 2 years, various task forces and working groups around the globe have identified pivotal topics and key issues to address if we are to realize such networks in a timely fashion. In response, industry, government, and academia undertook efforts to address these topics and issues. A workshop was organized to provide a forum to assess the current state-of-the-art, identify key issues, and highlight the emerging trends in the next-generation architectures, data protocol development, communication interoperability, and applications. The Satellite Networks: Architectures, Applications, and Technologies Workshop was hosted by the Space Communication Program at the NASA Lewis Research Center in Cleveland, Ohio. Nearly 300 executives and technical experts from academia, industry, and government, representing the United States and eight other countries, attended the event (June 2 to 4, 1998). The program included seven panels and invited sessions and nine breakout sessions in which 42 speakers presented on technical topics. The proceedings covers a wide range of topics: access technology and protocols, architectures and network simulations, asynchronous transfer mode (ATM) over satellite networks, Internet over satellite networks, interoperability experiments and applications, multicasting, NASA interoperability experiment programs, NASA mission applications, and Transmission Control Protocol/Internet Protocol (TCP/IP) over satellite: issues, relevance, and experience.

Composite materials have emerged as the materials of choice for increasing the performance and reducing the weight and cost of military, general aviation, and transport aircraft and space launch vehicles. Major advancements have been made in the ability to design, fabricate, and analyze large complex aerospace structures. The recent efforts by Boeing and Airbus to incorporate composite into primary load carrying structures of large commercial transports and to certify the airworthiness of these structures is evidence of the significant advancements made in understanding and use of these materials in real world aircraft. NASA has been engaged in research on composites since the late 1960 s and has worked to address many development issues with these materials in an effort to ensure safety, improve performance, and improve affordability of air travel for the public good. This research has ranged from synthesis of advanced resin chemistries to development of mathematical analyses tools to reliably predict the response of built-up structures under combined load conditions. The lessons learned from this research are highlighted with specific examples to illustrate the problems encountered and solutions to these problems. Examples include specific technologies related to environmental effects, processing science, fabrication technologies, nondestructive inspection, damage tolerance, micromechanics, structural mechanics, and residual life prediction. The current state of the technology is reviewed and key issues requiring additional research identified. Also, grand challenges to be solved for expanded use of composites in aero structures are identified.

2018-06-01

Despite the positive dynamics in the growth of RES-based power production in electric power systems of many countries, the further development of commercially mature technologies of wind and solar generation is often constrained by the existing grid infrastructure and conventional energy supply practices. The integration of large wind and solar power plants into a single power grid and the development of microgeneration require the widespread introduction of a new smart grid technology cluster (smart power grids), whose technical advantages over the conventional ones have been fairly well studied, while issues of their economic effectiveness remain open. Estimation and forecasting potential economic effects from the introduction of innovative technologies in the power sector during the stage preceding commercial development is a methodologically difficult task that requires the use of knowledge from different sciences. This paper contains the analysis of smart grid project implementation in Europe and the United States. Interval estimates are obtained for their basic economic parameters. It was revealed that the majority of smart grid implemented projects are not yet commercially effective, since their positive externalities are usually not recognized on the revenue side due to the lack of universal methods for public benefits monetization. The results of the research can be used in modernization and development planning for the existing grid infrastructure both at the federal level and at the level of certain regions and territories.

Technologies for Continuous Glucose Monitoring: Current Problems and Future Promises

2010-01-01

Devices for continuous glucose monitoring (CGM) are currently a major focus of research in the area of diabetes management. It is envisioned that such devices will have the ability to alert a diabetes patient (or the parent or medical care giver of a diabetes patient) of impending hypoglycemic/hyperglycemic events and thereby enable the patient to avoid extreme hypoglycemic/hyperglycemic excursions as well as minimize deviations outside the normal glucose range, thus preventing both life-threatening events and the debilitating complications associated with diabetes. It is anticipated that CGM devices will utilize constant feedback of analytical information from a glucose sensor to activate an insulin delivery pump, thereby ultimately realizing the concept of an artificial pancreas. Depending on whether the CGM device penetrates/breaks the skin and/or the sample is measured extracorporeally, these devices can be categorized as totally invasive, minimally invasive, and noninvasive. In addition, CGM devices are further classified according to the transduction mechanisms used for glucose sensing (i.e., electrochemical, optical, and piezoelectric). However, at present, most of these technologies are plagued by a variety of issues that affect their accuracy and long-term performance. This article presents a critical comparison of existing CGM technologies, highlighting critical issues of device accuracy, foreign body response, calibration, and miniaturization. An outlook on future developments with an emphasis on long-term reliability and performance is also presented. PMID:21129353

Using mobile technologies for assessment and learning in practice settings: a case study.

Dearnley, Chris; Haigh, Jackie; Fairhall, John

2008-05-01

The aim of this project was to explore the feasibility and identify the issues of using mobile technologies in the assessment of health and social care students in practice settings. We report here on a case study, which took place between a University department and varied clinical settings where students were on placement. Twenty-nine student midwives and five members of lecturing staff took part in the study and were issued with PocketPCs on which to record assessment documentation including action plans and evidence of achieving performance criteria. Qualitative data were obtained from three focus groups with student midwives and individual interviews with their link lecturers and quantitative data were gathered through short questionnaires to provide simple descriptive statistics. Findings indicated that students preferred the neatness and durability of the PocketPC to the paper based format, which became worn overtime. The ability to add to notes and references as and when appropriate was welcomed. However, anxiety about losing the device or material stored within it proved to be a major constraint. Lecturing staff found that synchronising the device with the University electronic diary system was extremely useful whilst clinical staff approached the change with varying levels of acceptance or dismissal. Introducing mobile technology into the clinical setting will require a significant shift in culture and a significant level of training and support.

Java-based cryptosystem for PACS and tele-imaging

Tjandra, Donny; Wong, Stephen T. C.; Yu, Yuan-Pin

1998-07-01

Traditional PACS systems are based on two-tier client server architectures, and require the use of costly, high-end client workstations for image viewing. Consequently, PACS systems using the two-tier architecture do not scale well as data increases in size and complexity. Furthermore, use of dedicated viewing workstations incurs costs in deployment and maintenance. To address these issues, the use of digital library technologies, such as the World Wide Web, Java, and CORBA, is being explored to distribute PACS data to serve a broader range of healthcare providers in an economic and efficient manner. Integration of PACS systems with digital library technologies allows access to medical information through open networks such as the Internet. However, use of open networks to transmit medical data introduces problems with maintaining privacy and integrity of patient information. Cryptography and digital timestamping is used to protect sensitive information from unauthorized access or tampering. A major concern when using cryptography and digital timestamping is the performance degradation associated with the mathematical calculations needed to encrypt/decrypt an image dataset, or to calculate the hash value of an image. The performance issue is compounded by the extra layer associated with the CORBA middleware, and the use of programming languages interpreted at the client side, such as Java. This paper study the extent to which Java-based cryptography and digital timestamping affects performance in a PACS system integrated with digital library technologies.

Significant research results relative to that milestone were presented. The opening session provided a brief overview of the Program and status of the Phase H plan. The next five sessions were technically oriented and highlighted recent significant analytical and experimental accomplishments. The last Session included a panel discussion by the Session Chairs, summarizing the progress seen to date and discussing issues relative to further advances in technology necessary to achieve the Program Goals. Attendance at the Symposium was by invitation only and included only industry, academic, and government participants who are actively involved in the High-Speed Research Program. The technology presented in this meeting is considered commercially sensitive.

Opportunities and Challenges in Application of Forward Osmosis in Food Processing.

PubMed

Rastogi, Navin K

2016-01-01

Food processing and preservation technologies must maintain the fresh-like characteristics of food while providing an acceptable and convenient shelf life as well as assuring safety and nutritional value. Besides, the consumers' demand for the highest quality convenience foods in terms of natural flavor and taste, free from additives and preservatives necessitated the development of a number of membrane-based non-thermal approaches to the concentration of liquid foods, of which forward osmosis has proven to be the most valuable one. A series of recent publications in scientific journals have demonstrated novel and diverse uses of this technology for food processing, desalination, pharmaceuticals as well as for power generation. Its novel features, which include the concentration of liquid foods at ambient temperature and pressure without significant fouling of membrane, made the technology commercially attractive. This review aims to identify the opportunities and challenges associated with this technology. At the same time, it presents a comprehensive account of recent advances in forward osmosis technology as related to the major issues of concern in its rapidly growing applications in food processing such as concentration of fruit and vegetable juices (grape, pineapple, red raspberry, orange, and tomato juice and red radish juice) and natural food colorants (anthocyanin and betalains extracts). Several vibrant and vital issues such as recent developments in the forward osmosis membrane and concentration polarization aspects have been also addressed. The asymmetric membrane used for forward osmosis poses newer challenges to account both external and internal concentration polarization leading to significant reduction in flux. The recent advances and developments in forward osmosis membrane processes, mechanism of water transport, characteristics of draw solution and membranes as well as applications of forward osmosis in food processing have been discussed.

Organizations try to outsource their activities as much as possible in order to prevent the problems and use organizational capabilities in Information Technology (IT) field. The purpose of this paper was first, to express the effective criteria for selecting suppliers of IT services, second, to explain the advantages and disadvantages of outsourcing IT in hospitals. This study was narrative review, which search was conducted with the help of libraries, books, conference proceedings, and databases of Science Direct, PubMed, Proquest, Springer, and SID (Scientific Information Database). In our searches, we employed the following keywords and their combinations: Outsourcing, information technology, hospital, decision making, and criteria. The preliminary search resulted in 120 articles, which were published between 2000 and 2013 during July 2013. After a careful analysis of the content of each paper, a total of 46 papers were selected based on their relevancy. The criteria and sub-criteria influencing outsourcing decisions in Iranian hospitals were identified in six major categories including administrative issues, issues related to the service/product, technology factors, environmental factors, risks, and economic factors associated with 15 sub-criteria containing business integration, dependence on suppliers, human resources, focus on core competencies, facilities and physical capital, innovation, quality, speed of service delivery, flexibility, market capabilities, geographical location, security, management control, cost, and financial capability. Identify the advantages and disadvantages of outsourcing and effective criteria in IT services supplier selection causes the managers be able to take the most appropriate decision to select supplier of IT services. This is a general review on influencing criteria for electing of supplier of information technology services in hospitals. PMID:25540781

With the United States joining other countries in national efforts to reap the many benefits that use of health information technology can bring for health care quality and savings, sobering reports recall the complexity and difficulties of implementing even smaller-scale systems. Despite best practice research that identified success factors for health information technology projects, a majority, in some sense, still fail. Similar problems plague a variety of different kinds of applications, and have done so for many years. Ten AMIA working groups sponsored a workshop at the AMIA Fall 2006 Symposium. It was entitled "Avoiding The F-Word: IT Project Morbidity, Mortality, and Immortality" and focused on this under-addressed problem. PARTICIPANTS discussed communication, workflow, and quality; the complexity of information technology undertakings; the need to integrate all aspects of projects, work environments, and regulatory and policy requirements; and the difficulty of getting all the parts and participants in harmony. While recognizing that there still are technical issues related to functionality and interoperability, discussion affirmed the emerging consensus that problems are due to sociological, cultural, and financial issues, and hence are more managerial than technical. Participants drew on lessons from experience and research in identifying important issues, action items, and recommendations to address the following: what "success" and "failure" mean, what contributes to making successful or unsuccessful systems, how to use failure as an enhanced learning opportunity for continued improvement, how system successes or failures should be studied, and what AMIA should do to enhance opportunities for successes. The workshop laid out a research agenda and recommended action items, reflecting the conviction that AMIA members and AMIA as an organization can take a leadership role to make projects more practical and likely to succeed in health care settings.
