Environmental interactions in space exploration: Environmental interactions working group

NASA Technical Reports Server (NTRS)

Kolecki, Joseph C.; Hillard, G. Barry

1992-01-01

With the advent of the Space Exploration Initiative, the possibility of designing and using systems on scales heretofore unattempted presents exciting new challenges in systems design and space science. The environments addressed by the Space Exploration Initiative include the surfaces of the Moon and Mars, as well as the varied plasma and field environments which will be encountered by humans and cargo enroute to these destinations. Systems designers will need to understand environmental interactions and be able to model these mechanisms from the earliest conceptual design stages through design completion. To the end of understanding environmental interactions and establishing robotic precursor mission requirements, an Environmental Interactions Working Group was established as part of the Robotic Missions Working Group. The working group is described, and its current activities are updated.

(1) To examine whether prevalence of burnout is higher among community psychiatric nurses working under recently introduced job specific work systems than among public health nurses (PHNs) engaged in other public health services. (2) To identify work environment factors potentially contributing to burnout. Two groups were examined. The psychiatric group comprised 525 PHNs primarily engaged in public mental health services at public health centres (PHCs) that had adopted the job specific work system. The control group comprised 525 PHNs primarily engaged in other health services. Pines' Burnout Scale was used to measure burnout. Respondents were classified by burnout score into three groups: A (mentally stable, no burnout); B (positive signs, risk of burnout); and C (burnout present, action required). Groups B and C were considered representative of "burnout". A questionnaire was also prepared to investigate systems for supporting PHNs working at PHCs and to define emergency mental health service factors contributing to burnout. Final respondents comprised 785 PHNs. Prevalence of burnout was significantly higher in the psychiatric group (59.2%) than in the control group (51.5%). Responses indicating lack of job control and increased annual frequency of emergency overtime services were significantly correlated with prevalence of burnout in the psychiatric group, but not in the control group. Prevalence of burnout is significantly higher for community psychiatric nurses than for PHNs engaged in other services. Overwork in emergency services and lack of job control appear to represent work environment factors contributing to burnout.

The Earthcube Intelligent Systems for Geosciences Research Collaboration Network (IS-GEO RCN) represents an emerging community of interdisciplinary researchers aiming to create fundamental new capabilities for understanding Earth systems. Collaborative efforts across IS-GEO fields of study offer opportunities to accelerate scientific discovery and understanding. The IS-GEO community has an active membership of approximately 65 researchers and includes researchers from across the US, international members, and an early career committee. Current working groups are open to new participants and are focused on four thematic areas with regular coordination meetings and upcoming sessions at professional conferences. (1) The Sensor-based data Collection and Integration Working group looks at techniques for analyzing and integrating of information from heterogeneous sources, with a possible application for early warning systems. (2) The Geoscience Case Studies Working group is creating benchmark data sets to enable new collaborations between geoscientists and data scientists. (3) The Geo-Simulations Working group is evaluating the state of the art in practices for parametrizations, scales, and model integration. (4) The Education Working group is gathering, organizing and collecting all the materials from the different IS-GEO courses. Innovative IS-GEO applications will help researchers overcome common challenges while will redefining the frontiers of discovery across fields and disciplines. (Visit IS-GEO.org for more information or to sign up for any of the working groups.)

The Working Party has met twice since the last report: in Seoul, South Korea 2014, and in London, UK 2015, both in association with the International Society of Blood Transfusion (ISBT) Congress. As in previous meetings, matters pertaining to blood group antigen nomenclature were discussed. Eleven new blood group antigens were added to seven blood group systems. This brings the current total of blood group antigens recognized by the ISBT to 346, of which 308 are clustered within 36 blood groups systems. The remaining 38 antigens are currently unassigned to a known blood group system.

From Data-Sharing to Model-Sharing: SCEC and the Development of Earthquake System Science (Invited)

NASA Astrophysics Data System (ADS)

Jordan, T. H.

2009-12-01

Earthquake system science seeks to construct system-level models of earthquake phenomena and use them to predict emergent seismic behavior—an ambitious enterprise that requires high degree of interdisciplinary, multi-institutional collaboration. This presentation will explore model-sharing structures that have been successful in promoting earthquake system science within the Southern California Earthquake Center (SCEC). These include disciplinary working groups to aggregate data into community models; numerical-simulation working groups to investigate system-specific phenomena (process modeling) and further improve the data models (inverse modeling); and interdisciplinary working groups to synthesize predictive system-level models. SCEC has developed a cyberinfrastructure, called the Community Modeling Environment, that can distribute the community models; manage large suites of numerical simulations; vertically integrate the hardware, software, and wetware needed for system-level modeling; and promote the interactions among working groups needed for model validation and refinement. Various socio-scientific structures contribute to successful model-sharing. Two of the most important are “communities of trust” and collaborations between government and academic scientists on mission-oriented objectives. The latter include improvements of earthquake forecasts and seismic hazard models and the use of earthquake scenarios in promoting public awareness and disaster management.

The synthesis and modeling of ecological processes at multiple spatial and temporal scales involves bringing together and sharing data from numerous sources. This article describes a data and information system model that facilitates assembling, managing, and sharing diverse data from multiple disciplines, scales, and sites to support integrated ecological studies. Cross-site scientific-domain working groups coordinate the development of data associated with their particular scientific working group, including decisions about data requirements, data to be compiled, data formats, derived data products, and schedules across the sites. The Web-based data and information system consists of nodes for each working group plus a central node that provides data access, project information, data query, and other functionality. The approach incorporates scientists and computer experts in the working groups and provides incentives for individuals to submit documented data to the data and information system.

Cernelc, S; Vozelj, M

1991-01-01

Authors point out the morbidity of employees working in ventilation systems contaminated with various microorganisms. They analysed 96 workers exposed to air conditioning system (Group A), and 71 workers (Group B) breathing normal ambient air. The workers of both groups were subjected clinically by functionally and immunologically. Preparation of antigens "MMM" (Monday morning miseries) was used as an original method by Ajello et al. for producing antigens from systemic mycotic agents and subsequently modified. The aim of the present study is to evaluate the possibility of using ELISA in clinical practice for respiratory allergy diagnosis, and especially Hypersensitivity pneumonitis. Atopic status was determined by skin prick tests with common airborne allergens including Dermatophagoides pteronyssinus, ragweed, grasses and Aspergillus fumigatus., by Enzygnost--IgE (Behringwerke AG, Marburg) and for specific IgE by RAST technique (Pharmacia, Uppsala). The skin prick tests were performed with "MMM"-antigens. PEFR (Peak Expiratory Flow-Rate) was measured by using a Wright's peak flow meter. PEFR was recorded on Monday (first day at work) and Friday (the end of the working week). Measured values of PEFR in both groups of employees from Monday to Friday were elaborated by the Wilcoxon test. Culture of scrapings from air conditioning vents were obtained and water from the humidifier system also cultured. They were grown: T. vulgaris, Aspergillus fumigatus, Thermoactinomyces vulgaris and others. Results of questionnaires, clinical evaluation and diagnostical procedures in employees of Group A and B are as follows: Thirty eight workers in Group A had a positive clinical history of "Monday illness". In the symptomatic Group A we found in 8 cases abnormal chest roentgenogram. Further, there was no correlation between the presence of antibodies (ELISA) against MMM and pulmonary function abnormalities, as measured by either spirometry or DLCO. Further, we found good agreement between ELISA and prick test results with antigen MMM. Wilcoxon test showed a statistically significant difference between the two groups (0.01). The median or central value of PEFR reduction in Group A is 10.23 per cent, and in Group B 1.49 per cent. A 30 per cent reduction of PEFR was observed in 5.21 per cent of subjects in Group A. Exposure to ventilation systems contaminated with Thermophilic actinomyces may be responsible for increased morbidity and reduced performance of employees working in air conditioning systems. Particularly the main filter should be checked regularly. Moreover, regular microbiologic examinations of dust and water from air preventing chronic obstructive lung diseases in employees working in areas served by contaminated air conditioning systems.

Effect of overtime work on 24-hour ambulatory blood pressure.

Hayashi, T; Kobayashi, Y; Yamaoka, K; Yano, E

1996-10-01

Recently, the adverse effects of long working hours on the cardiovascular systems of workers in Japan, including "Karoshi" (death from overwork), have been the focus of social concern. However, conventional methods of health checkups are often unable to detect the early signs of such adverse effects. To evaluate the influence of overtime work on the cardiovascular system, we compared 24-hour blood pressure measurements among several groups of male white-collar workers. As a result, for those with normal blood pressure and those with mild hypertension, the 24-hour average blood pressure of the overtime groups was higher than that of the control groups; for those who periodically did overtime work, the 24-hour average blood pressure and heart rate during the busy period increased. These results indicate that the burden on the cardiovascular system of white-collar workers increases with overtime work.

Global Earth Observation System of Systems (GEOSS): Initial Actions to Enhance Data Sharing to Meet Societal Needs

NASA Astrophysics Data System (ADS)

Adang, T.

2006-05-01

Over 60 nations and 50 participating organizations are working to make the Global Earth Observation System of Systems (GEOSS) a reality. The U.S. contribution to GEOSS is the Integrated Earth Observation System (IEOS), with a vision of enabling a healthy public, economy and planet through an integrated, comprehensive, and sustained Earth observation system. The international Group on Earth Observations (GEO) and the U.S. Group on Earth Observations have developed strategic plans for both GEOSS and IEOS, respectively, and are now working the first phases of implementation. Many of these initial actions are data architecture related and are being addressed by architecture and data working groups from both organizations - the GEO Architecture and Data Committee and the USGEO Architecture and Data Management Working Group. NOAA has actively participated in both architecture groups and has taken internal action to better support GEOSS and IEOS implementation by establishing the Global Earth Observation Integrated Data Environment (GEO IDE). GEO IDE provides a "system of systems" framework for effective and efficient integration of NOAA's many quasi-independent systems, which individually address diverse mandates in such areas resource management, weather forecasting, safe navigation, disaster response, and coastal mapping among others. GEO IDE will have a services oriented architecture, allowing NOAA Line Offices to retain a high level of independence in many of their data management decisions, and encouraging innovation in pursuit of their missions. Through GEO IDE, NOAA partners (both internal and external) will participate in a well-ordered, standards-based data and information infrastructure that will allow users to easily locate, acquire, integrate and utilize NOAA data and information. This paper describes the initial progress being made by GEO and USGEO architecture and data working groups, a status report on GEO IDE development within NOAA, and an assessment of how GEO IDE can facilitate greater progress in GEOSS and IEOS development.

Space systems in the future will probably include high-voltage, high-power energy-storage and -production systems. Two such technologies are high-voltage ac and dc systems and high-power electrodynamic tethers. The working group identified several plasma interaction phenomena that will occur in the operation of these power systems. The working group felt that building an understanding of these critical interaction issues meant that several gaps in our knowledge had to be filled, and that certain aspects of dc power systems have become fairly well understood. Examples of these current collection are in quiescent plasmas and snap over effects. However, high-voltage dc and almost all ac phenomena are, at best, inadequately understood. In addition, there is major uncertainty in the knowledge of coupling between plasmas and large scale current flows in space plasmas. These gaps in the knowledge are addressed.

Groupware is a term describing an emerging computer software technology enhancing the ability of people to work together as a group, (a software driven 'group support system'). This project originated at the beginning of 1992 and reports were issued describing the activity through May 1995. These reports stressed the need for process as well as technology. That is, while the technology represented a computer assisted method for groups to work together, the Group Support System (GSS) technology als required an understanding of the facilitation process electronic meetings demand. Even people trained in traditional facilitation techniques did not necessarily aimlessly adopt groupware techniques. The latest phase of this activity attempted to (1) improve the facilitation process by developing training support for a portable groupware computer system, and (2) to explore settings and uses for the portable groupware system using different software, such as Lotus Notes.

Maintaining patients' social contacts through displaying nonverbal awareness information on mobile devices.

Ruschin, Detlef

2015-01-01

Awareness systems had been invented for supporting groups collaborating simultaneously over a network. They provide each group member with real-time information about the state of affairs on the remote locations of the other members. Awareness systems have also been observed to help remote collaborators develop the same shared sense of community that often emerges within co-located work groups, and this effect of creating or maintaining group cohesion is an important goal in itself. Purely social awareness systems can be employed by any kind of group, e.g. families, without shared work tasks. As a means of preventing loneliness they can be regarded as examples of biomedical technology. In this paper a demonstrator of an awareness-enhanced instant messaging system for elderly living alone is described along with assumptions about group processes that led to its specification.

McDonald, K. R.; Faundeen, J. L.; Petiteville, I.

2005-12-01

The Committee on Earth Observation Satellites (CEOS) was established in 1984 in response to a recommendation from the Economic Summit of Industrialized Nations Working Group on Growth, Technology, and Employment's Panel of Experts on Satellite Remote Sensing. CEOS participants are Members, who are national or international governmental organizations who operate civil spaceborne Earth observation satellites, and Associates who are governmental organizations with civil space programs in development or international scientific or governmental bodies who have an interest in and support CEOS objectives. The primary objective of CEOS is to optimize benefits of satellite Earth observations through cooperation of its participants in mission planning and in development of compatible data products, formats, services, applications and policies. To pursue its objectives, CEOS establishes working groups and associated subgroups that focus on relevant areas of interest. While the structure of CEOS has evolved over its lifetime, today there are three permanent working groups. One is the Working Group on Calibration and Validation that addresses sensor-specific calibration and validation and geophysical parameter validation. A second is the Working Group on Education, Training, and Capacity Building that facilitates activities that enhance international education and training in Earth observation techniques, data analysis, interpretation and applications, with a particular focus on developing countries. The third permanent working group is the Working Group on Information Systems and Services (WGISS). The purpose of WGISS is to promote collaboration in the development of the systems and services based on international standards that manage and supply the Earth observation data and information from participating agencies' missions. WGISS places great emphasis on the use of demonstration projects involving user groups to solve the critical interoperability issues associated with the achievement of global services and its structure reflects that objective. The Technology and Services Subgroup initiates tasks to explore emerging technologies that can be employed to create data and information systems and to develop interoperable services. The interests of the subgroup span the full range of the information processing chain from the initial ingestion of satellite data into archives through to the incorporation of derived information into end-user applications. The subgroup has overseen the creation of an Interoperable Directory Network and an Interoperable Catalog System and has tasks that are investigating the use of new technologies such as Web Services, Grid, and Open Geographical Information Systems to provide enhanced capabilities. The WGISS Projects and Applications Subgroup works with outside organizations to understand their requirements and then helps them to exploit the tools and services available through WGISS and its members and associates. WGISS has instituted the concept of a WGISS Test Facility to test and develop information systems and services prototypes collaboratively with these organizations to meet their specific requirements. This approach has the dual benefit of addressing real information systems and services needs of science and applications projects and helping WGISS to expand and improve its capabilities based on the experience and lessons learned from working with the projects.

2011-01-01

PURPOSE This study investigated the strain of implants using a chewing simulator with strain gauges in mandibular implant-supported fixed prostheses under various dynamic loads. MATERIALS AND METHODS Three implant-supported 5-unit fixed prostheses were fabricated with three different occlusion types (Group I: Canine protected occlusion, Group II: Unilaterally balanced occlusion, Group III: Bilaterally balanced occlusion). Two strain gauges were attached to each implant abutment. The programmed dynamic loads (0 - 300 N) were applied using a chewing simulator (MTS 858 Mini Bionix II systems, MTS systems corp., Minn, USA) and the strains were monitored. The statistical analyses were performed using the paired t-test and the ANOVA. RESULTS The mean strain values (MSV) for the working sides were 151.83 µε, 176.23 µε, and 131.07 µε for Group I, Group II, and Group III, respectively. There was a significant difference between Group II and Group III (P < .05). Also, the MSV for non-working side were 58.29 µε, 72.64 µε, and 98.93 µε for Group I, Group II, and Group III, respectively. One was significantly different from the others with a 95% confidence interval (P < .05). CONCLUSION The MSV for the working side of Groups I and II were significantly different from that for the non-working side (Group I: t = 7.58, Group II: t = 6.25). The MSV for the working side of Group II showed significantly larger than that of Group III (P < .01). Lastly, the MSV for the non-working side of Group III showed significantly larger than those of Group I or Group II (P < .01). PMID:21503186

2007-06-01

To explore concrete approaches to socio-technical design of collaborative healthcare information systems and to design a groupware technology for collaborative clinical trial protocol writing. We conducted "quick and dirty ethnography" through semi-structured interviews, observational studies, and work artifacts analysis to understand the group work for protocol development. We used participatory design through evolutionary prototyping to explore the feature space of a collaborative writing system. Our design strategies include role-based user advocacy, formative evaluation, and change management. Quick and dirty ethnography helped us efficiently understand relevant work practice, and participatory design helped us engage users into design and bring out their tacit work knowledge. Our approach that intertwined both techniques helped achieve a "work-informed and user-oriented" design. This research leads to a collaborative writing system that supports in situ communication, group awareness, and effective work progress tracking. The usability evaluation results have been satisfactory. The system design is being transferred to an organizational tool for daily use.

The objective of this study was to evaluate the effect of root canal preparation with single-file reciprocating systems at different working lengths on the development of apical microcracks using micro-computed tomographic (micro-CT) imaging. Forty extracted human mandibular incisors were randomly assigned to 4 groups (n=10) according to the systems and working length used to prepare the root canals: Group A - WaveOne Gold at apical foramen (AF), Group B - WaveOne Gold 1 mm short of the AF (AF-1 mm), Group C - Unicone (AF) and Group D - Unicone (AF-1 mm). Micro-CT scanning was performed before and after root canal preparation at an isotropic resolution of 14 µm. Then, three examiners assessed the cross-sectional images generated to detect microcracks in the apical portion of the roots. Apical microcracks were visualized in 3, 1, 1, and 3 specimens in groups A, B, C, and D, respectively. All these microcracks observed after root canal preparation already existed prior to instrumentation, and no new apical microcrack was detected. For all groups, the number of slices presenting microcracks after root canal preparation was the same as before canal preparation. Root canal preparation with WaveOne Gold and Unicone, regardless of the working length, was not associated with apical microcrack formation.

Aydt, Ruth; Gunter, Dan; Quesnel, Darcy; Smith, Warren; Taylor, Valerie; Biegel, Bryan (Technical Monitor)

2001-01-01

This document presents a simple case study of a Grid performance system based on the Grid Monitoring Architecture (GMA) being developed by the Grid Forum Performance Working Group. It describes how the various system components would interact for a very basic monitoring scenario, and is intended to introduce people to the terminology and concepts presented in greater detail in other Working Group documents. We believe that by focusing on the simple case first, working group members can familiarize themselves with terminology and concepts, and productively join in the ongoing discussions of the group. In addition, prototype implementations of this basic scenario can be built to explore the feasibility of the proposed architecture and to expose possible shortcomings. Once the simple case is understood and agreed upon, complexities can be added incrementally as warranted by cases not addressed in the most basic implementation described here. Following the basic performance monitoring scenario discussion, unresolved issues are introduced for future discussion.

2010-05-01

The purpose of this study is to describe nurse managers' perceptions of the use of electronic information systems in their daily work. Several kinds of software are used for administrative and information management purposes in health care organizations, but the issue has been studied less from nurse managers' perspective. The material for this qualitative study was acquired according to the principles of focus group interview. Altogether eight focus groups were held with 48 nurse managers from both primary and specialized health care organizations. The nurse managers were asked in focus groups to describe the use of information systems in their daily work in addition to some other themes. The material was analyzed by inductive content analysis using ATLAS.ti computer program. The main category "pros and cons of using information systems in nursing management" summarized the nurse managers' perceptions of using electronic information systems. The main category consisted of three sub-categories: (1) nurse managers' perceptions of the use of information technology; (2) usability of management information systems; (3) development of personnel competencies and work processes. The nurse managers made several comments on the implementation of immature electronic information systems which caused inefficiencies in working processes. However, they considered electronic information systems to be essential elements of their daily work. Furthermore, the nurse managers' descriptions of the pros and cons of using information systems reflected partly the shortcomings of strategic management and lack of coordination in health care organizations.

The Biopharmaceutics Classification System (BCS) allows compounds to be classified based on their in vitro solubility and intestinal permeability. The BCS has found widespread use in the pharmaceutical community as an enabling guide for the rational selection of compounds, formulation for clinical advancement and generic biowaivers. The Pediatric Biopharmaceutics Classification System (PBCS) working group was convened to consider the possibility of developing an analogous pediatric based classification system. Since there are distinct developmental differences that can alter intestinal contents, volumes, permeability and potentially biorelevant solubilities at the different ages, the PBCS working group focused on identifying age specific issues that would need to be considered in establishing a flexible, yet rigorous PBCS. Objective To summarize the findings of the PBCS working group and provide insights into considerations required for the development of a pediatric based biopharmaceutics classification system. Methods Through several meetings conducted both at The Eunice Kennedy Shriver National Institute of Child Health, Human Development (NICHD)-US Pediatric Formulation Initiative (PFI) workshop (November 2011) and via teleconferences, the PBCS working group considered several high level questions that were raised to frame the classification system. In addition, the PBCS working group identified a number of knowledge gaps that would need to be addressed in order to develop a rigorous PBCS. Results It was determined that for a PBCS to be truly meaningful, it would need to be broken down into several different age groups that would account for developmental changes in intestinal permeability, luminal contents, and gastrointestinal transit. Several critical knowledge gaps where identified including: 1) a lack of fully understanding the ontogeny of drug metabolizing enzymes and transporters along the gastrointestinal (GI) tract, in the liver and in the kidney; 2) an incomplete understanding of age-based changes in the GI, liver and kidney physiology; 3) a clear need to better understand age-based intestinal permeability and fraction absorbed required to develop the PBCS; 4) a clear need for the development and organization of pediatric tissue biobanks to serve as a source for ontogenic research; and 5) a lack of literature published in age-based pediatric pharmacokinetics in order to build Physiologically- and Population-Based Pharmacokinetic (PBPK) databases. Conclusions To begin the process of establishing a PBPK model, ten pediatric therapeutic agents were selected (based on their adult BCS classifications). Those agents should be targeted for additional research in the future. The PBCS working group also identified several areas where a greater emphasis on research is needed to enable the development of a PBCS. PMID:23149009

This paper reports the results of implementing a pilot case management system for work injuries in Hong Kong. The case management approach was characterized by use of a case manager who worked closely with each of the reported injury cases. The case manager undertook the roles of assessor, referral agent, counselor, work-site liaison, and return-to-work (RTW) expert. A quasi-experimental study design was used. The study compared the RTW and workers' compensation outcomes in injured workers in a cleaning company in a case management group (n = 296) and a conventional rehabilitation group (n = 137). Outcomes of the intervention were followed up at 6 months. The results indicated that the RTW rate was 97.0% and 94.2% for the case management and conventional rehabilitation groups respectively, with no significant differences between them. Participants in the case management group had significantly fewer days of sick leave (mean = 27.5 and 41.6 days, respectively) and lower compensation costs (mean = HK$7,212.2 and $20,617.3, respectively) than those in the comparison group. Age of the participants was found to influence the outcomes with those who were between 41 and 50 years old and received case management intervention had shorter sick leave and lower cost of compensation than their conventional rehabilitation counterpart. The majority of the participants who had returned to work in both the case management (95.8%) and the conventional rehabilitation (96.2%) groups were found to maintain their work status 6 months after the intervention. The findings suggested that applying the case management approach to the Hong Kong workers' compensation system was more effective overall. Nevertheless, the inherent problems associated with implementing such an approach within the existing system, which focuses on compensation and medical interventions, remained unresolved.

Distributed intelligent systems can be distinguished by the models that they use. The model developed focuses on layered multiagent system conceived of as a bureaucracy in which a distributed data base serves as a central means of communication. The various generic bureaus of such a system is described and a basic vocabulary for such systems is presented. In presenting the bureaus and vocabularies, special attention is given to the sorts of reasonings that are appropriate. A bureaucratic model has a hierarchy of master system and work group that organizes E agents and B agents. The master system provides the administrative services and support facilities for the work groups.

VLBI2010: An Overview

2010-01-01

The first concrete actions toward a next generation system for geodetic VLBI began in 2003 when the IVS initiated Working Group 3 to investigate requirements for a new system. The working group set out ambitious performance goals and sketched out initial recommendations for the system. Starting in 2006, developments continued under the leadership of the VLBI2010 Committee (V2C) in two main areas: Monte Carlo simulators were developed to evaluate proposed system changes according to their impact on IVS final products, and a proof-of-concept effort sponsored by NASA was initiated to develop next generation systems and verify the concepts behind VLBI2010. In 2009, the V2C produced a progress report that summarized the conclusions of the Monte Carlo work and outlined recommendations for the next generation system in terms of systems, analysis, operations, and network configuration. At the time of writing: two complete VLBI2010 signal paths have been completed and data is being produced; a number of VLBI2010 antenna projects are under way; and a VLBI2010 Project Executive Group (V2PEG) has been initiated to provide strategic leadership.

[Some occupational determinants of work disability].

Occupational determinants play a significant role in the studies of the causes of work disability. The duration of employment is that particular variable, frequently analysed, which reflects indirectly the effect of work conditions on the worker's health state and also on his her disease-related work disability. Therefore, the aim of this work was to show the difference in sick absenteeism between various occupational groups, depending on the duration of employment. The empirical material embraced data on work disability, among workers employed in the automative industry plant during the years 1989-94. Out of 8,599 persons covered with the study, 77% left the job, including 7% of those who left the job because of health problems. An analysis of the impact of occupational determinants on the sick absenteeism was carried out on the basis of the absenteeism rate adjusted by age, sex and occupational activity in groups of the production, auxilliary and administrative workers, as well as in occupational groups exposed to possibly similar harmful factors. The duration of worker's employment in the plant showed a positive influence on sick absenteeism, since together with extended period of employment the decrease in the rate of general sick absenteeism was observed. However, in a number of disease categories an increase in absenteeism together with extended duration of employment, and a high level of absenteeism among workers involved directly in the production, were noted. This proves an adverse effect of work conditions on work disability among workers. The effect of harmful factors present at workposts is also confirmed by the increasing sick absenteeism together with the prolonged duration of employment in various occupational groups. In the group of welders the highest level of sick absenteeism was observed among persons with duration of employment ranging from 11 to 20 years (rate: 10.52), and it was related to diseases of the respiratory (3.10) and circulatory (2.09) systems. In this group the increase in absenteeism together with prolonged duration of employment was related to diseases of the genitourinary system (about fourfold), musculoskeletal system (about threefold) and nervous system and sense organs (about 20%). It may be concluded that in selected high risk occupational groups, the duration of employment may reflect the effect of work conditions on workers' sick absenteeism, and the analysis of work disability caused by individual diseases provides an image of health effects due to hazards to which those groups are exposed.

The aim of this study was to explore factors that ameliorate work ability by focusing on workers' capacity to deal with stress.The subjects were 1,330 workers from the Japanese information technology (IT) sector. Each subject completed questionnaires in 2011 and 2012 that consisted of the work ability index (WAI), the three-item sense of coherence (SOC), and the Mental Health Improvement and Reinforcement Research of Recognition (MIRROR). The results of the WAI were also obtained in 2013. The median SOC score in 2011 was used to divide the subjects into two groups, the Low SOC group and the High SOC group, then we verified the factors that contributed to improved work ability in both of these groups over a two-year period. Results indicate that an improvement in work ability in the Low SOC group could be predicted by giving workers opportunities for education or training, by making efforts to reduce the stress of commuting, by clarifying their assignments, and by establishing support systems when troubles occur. For the High SOC group, such improvements could be predicted by giving workers job control, by giving education or training for the promotion of their abilities, and by establishing a system for assuming responsibility. In conclusion, improvements in the work environment can increase the work ability of Japanese IT workers in conformity with their capacity to deal with stress.

Ullman, Richard E.; Enloe, Yonsook

2007-01-01

NASA has impaneled several internal working groups to provide recommendations to NASA management on ways to evolve and improve Earth Science Data Systems. One of these working groups is the Standards Process Group (SPC). The SPG is drawn from NASA-funded Earth Science Data Systems stakeholders, and it directs a process of community review and evaluation of proposed NASA standards. The working group's goal is to promote interoperability and interuse of NASA Earth Science data through broader use of standards that have proven implementation and operational benefit to NASA Earth science by facilitating the NASA management endorsement of proposed standards. The SPC now has two years of experience with this approach to identification of standards. We will discuss real examples of the different types of candidate standards that have been proposed to NASA's Standards Process Group such as OPeNDAP's Data Access Protocol, the Hierarchical Data Format, and Open Geospatial Consortium's Web Map Server. Each of the three types of proposals requires a different sort of criteria for understanding the broad concepts of "proven implementation" and "operational benefit" in the context of NASA Earth Science data systems. We will discuss how our Standards Process has evolved with our experiences with the three candidate standards.

Group work as an incentive for learning – students’ experiences of group work

PubMed Central

Hammar Chiriac, Eva

2014-01-01

Group work is used as a means for learning at all levels in educational systems. There is strong scientific support for the benefits of having students learning and working in groups. Nevertheless, studies about what occurs in groups during group work and which factors actually influence the students’ ability to learn is still lacking. Similarly, the question of why some group work is successful and other group work results in the opposite is still unsolved. The aim of this article is to add to the current level of knowledge and understandings regarding the essence behind successful group work in higher education. This research is focused on the students’ experiences of group work and learning in groups, which is an almost non-existing aspect of research on group work prior to the beginning of the 21st century. A primary aim is to give university students a voice in the matter by elucidating the students’ positive and negative points of view and how the students assess learning when working in groups. Furthermore, the students’ explanations of why some group work ends up being a positive experience resulting in successful learning, while in other cases, the result is the reverse, are of interest. Data were collected through a study-specific questionnaire, with multiple choice and open-ended questions. The questionnaires were distributed to students in different study programs at two universities in Sweden. The present result is based on a reanalysis and qualitative analysis formed a key part of the study. The results indicate that most of the students’ experiences involved group work that facilitated learning, especially in the area of academic knowledge. Three important prerequisites (learning, study-social function, and organization) for group work that served as an effective pedagogy and as an incentive for learning were identified and discussed. All three abstractions facilitate or hamper students’ learning, as well as impact their experiences with group work. PMID:24926282

NASA's Earth Science Data Systems Working Groups (ESDSWG) was created over 10 years ago. The role of the ESDSWG is to make recommendations relevant to NASA's Earth science data systems from users' experiences. Each group works independently focusing on a unique topic. Participation in ESDSWG groups comes from a variety of NASA-funded science and technology projects, including MEaSUREs and ROSS. Participants include NASA information technology experts, affiliated contractor staff and other interested community members from academia and industry. Recommendations from the ESDSWG groups will enhance NASA's efforts to develop long term data products. The Airborne Metadata Working Group is evaluating the suitability of the current Common Metadata Repository (CMR) and Unified Metadata Model (UMM) for airborne data sets and to develop new recommendations as necessary. The overarching goal is to enhance the usability, interoperability, discovery and distribution of airborne observational data sets. This will be done by assessing the suitability (gaps) of the current UMM model for airborne data using lessons learned from current and past field campaigns, listening to user needs and community recommendations and assessing the suitability of ISO metadata and other standards to fill the gaps. The Time Series Working Group (TSWG) is a continuation of the 2015 Time Series/WaterML2 Working Group. The TSWG is using a case study-driven approach to test the new Open Geospatial Consortium (OGC) TimeseriesML standard to determine any deficiencies with respect to its ability to fully describe and encode NASA earth observation-derived time series data. To do this, the time series working group is engaging with the OGC TimeseriesML Standards Working Group (SWG) regarding unsatisfied needs and possible solutions. The effort will end with the drafting of an OGC Engineering Report based on the use cases and interactions with the OGC TimeseriesML SWG. Progress towards finalizing recommendations will be presented at the meeting.

2012-12-01

In September 2010 IAU Commission 4, Ephemerides, organized a working group to provide a recommendation for a preferred format for solar system ephemerides. The purpose of this recommendation is to provide easy access to a wide range of solar system ephemerides for users. The working group, chaired by Hilton, includes representatives from each of the major planetary ephemeris groups and representatives from the satellite and asteroid ephemeris communities. The working group has tentatively decided to recommend the SPK format developed by the Jet Propulsion Laboratory's Navigation and Ancillary Information Facility for use with its SPICE Toolkit. Certain details, however, must still be resolved before a final recommendation is made by the working group. An update is also provided to ongoing analysis comparing the three high accuracy planetary ephemerides, DE421, EPM2008, and INPOP10a. The principal topics of this update are: replacing the INPOP08 ephemeris with the INPOP10a ephemeris, making the comparisons with respect to DE421 rather than DE405, and comparing the TT - TDB values determined in EPM2008 and INPOP10a with the Fairhead & Bretagnon (1990, A&A, 229, 240) model used in DE421 as T_eph.

2010-01-01

Controversy exists regarding the role of cerebellar systems in cognition and whether working memory compromise commonly marking alcoholism can be explained by compromise of nodes of corticocerebellar circuitry. We tested 17 alcoholics and 31 age-matched controls with dual-task, working memory paradigms. Interference tasks competed with verbal and spatial working memory tasks using low (three item) or high (six item) memory loads. Participants also underwent structural MRI to obtain volumes of nodes of the frontocerebellar system. On the verbal working memory task, both groups performed equally. On the spatial working memory with the high-load task, the alcoholic group was disproportionately more affected by the arithmetic distractor than were controls. In alcoholics, volumes of the left thalamus and left cerebellar Crus I volumes were more robust predictors of performance in the spatial working memory task with the arithmetic distractor than the left frontal superior cortex. In controls, volumes of the right middle frontal gyrus and right cerebellar Crus I were independent predictors over the left cerebellar Crus I, left thalamus, right superior parietal cortex, or left middle frontal gyrus of spatial working memory performance with tracking interference. The brain–behavior correlations suggest that alcoholics and controls relied on the integrity of certain nodes of corticocerebellar systems to perform these verbal and spatial working memory tasks, but that the specific pattern of relationships differed by group. The resulting brain structure–function patterns provide correlational support that components of this corticocerebellar system not typically related to normal performance in dual-task conditions may be available to augment otherwise dampened performance by alcoholics.

Injuries in the military: a review and commentary focused on prevention.

2000-04-01

In November 1996, the Armed Forces Epidemiological Board (AFEB) Injury Prevention and Control Work Group issued a report that cited injuries as the leading cause of morbidity and mortality among military service members. This article reviews the types and categories of military morbidity and mortality data examined by the AFEB work group and the companion Department of Defense (DoD) Injury Surveillance and Prevention Work Group. This article further uses the injury data reviewed to illustrate the role of surveillance and research in injury prevention. The review provides the context for discussion of the implications of the AFEB work group's findings for the prevention of injuries in the military. The AFEB work group consisted of 11 civilian injury epidemiologists, health professionals and scientists from academia, and other non-DoD government agencies, plus six military liaison officers. Injury data from medical databases were provided to the civilian experts on the AFEB work group by the all-military DoD Injury Surveillance and Prevention Work Group. The AFEB work group assessed the value of each database to the process of prevention and made recommendations for improvement and use of each data source. Both work groups found that injuries were the single leading cause of deaths, disabilities, hospitalizations, outpatient visits, and manpower losses among military service members. They also identified numerous data sources useful for determining the causes and risk factors for injuries. Those data sources indicate that training injuries, sports, falls, and motor vehicle crashes are among the most important causes of morbidity for military personnel. While the work group recommends ways to prevent injuries, they felt the top priority for injury prevention must be the formation of a comprehensive medical surveillance system. Data from this surveillance system must be used routinely to prioritize and monitor injury and disease prevention and research programs. The success of injury prevention will depend not just on use of surveillance but also partnerships among the medical, surveillance, and safety agencies of the military services as well as the military commanders, other decision makers, and service members whose direct actions can prevent injuries and disease.

We investigated the working behavior of part-time occupational physicians using practical recording sheets to clarify issues of occupational physicians' activities according to industrial groups or size of business. We collected 561 recording sheets in 96 industries from 11 part-time occupational physicians as collaborators, who volunteered to be a part of this research. We collected a variety of information from the practical recording sheets, including the industry in which each occupational physician was employed, the annual number of times of work attendance, occupational physician-conducted workplace patrol, and employee health management. We investigated their annual practices regarding work environment management, work management, health management, and general occupational health management. In addition, we analyzed the differences between the secondary and tertiary industry groups and between the group of offices employing 100 people or fewer (≤100 group) and 101 people and above (≥101 group) in each industry group. The median work attendance by all occupational physicians was four times a year; the tertiary industry group had a significantly lower rate of work attendance than the secondary industry group. The occupational physicians' participation in risk assessment, mental health measures or overwork prevention, and the formulation of the occupational health management system and the annual plan were significantly lower in the tertiary industry group than in the secondary industry group. We observed that for the annual number of times of work attendance, occupational physician-conducted workplace patrol was significantly lower in the ≤100 group than in the ≥101 group in each industry group. These findings show that occupational physicians' activities have not been conducted enough in tertiary industries and small-sized offices employing ≤100 people. It would be necessary to evaluate how to provide occupational health service or appropriate occupational physicians' activities for small-sized offices or tertiary industries. Thereafter, it would likely be beneficial to construct a system to support the activities of part-time occupational physicians as well as the activity of occupational health at workplaces.

Strategy for outer planets exploration

NASA Technical Reports Server (NTRS)

1975-01-01

NASA's Planetary Programs Office formed a number of scientific working groups to study in depth the potential scientific return from the various candidate missions to the outer solar system. The results of these working group studies were brought together in a series of symposia to evaluate the potential outer planet missions and to discuss strategies for exploration of the outer solar system that were consistent with fiscal constraints and with anticipated spacecraft and launch vehicle capabilities. A logical, scientifically sound, and cost effective approach to exploration of the outer solar system is presented.

Adding a vocational focus to mental health rehabilitation.

PubMed

Blankertz, L; Robinson, S

1996-11-01

The study examined the effect of adding two employment specialists to the staff of a community mental health center; their sole responsibility was to develop the skills and positive work attitudes that clients with severe mental illness need to enter the state vocational rehabilitation system or to seek employment. A total of 122 clients were randomly assigned to a program with an employment specialist or to a control group with no specialized vocational services. Clients in the program were taught work skills and attitudes in group and individual sessions and through a trial work experience. A schedule of rewards reinforced positive changes. Outcomes measured were skill gains, changes in work attitudes, attainment of employment, and entry into the state vocational rehabilitation system. At nine months, 34 of the 61 clients in the program achieved positive changes in vocational status that included competitive employment, participation in training and evaluation programs operated by the state vocational system, and formal referral to the system. Only one client in the control group was linked to the state system. Skill gains and positive changes in work attitudes were found for all program clients. Logistical regression suggested that program participation, rather than client characteristics, was an important predictor of a positive outcome. Over a relatively short time period, targeted vocational programs can help clients with severe mental illness develop the skills and attitudes necessary to attain employment or entry into the vocational rehabilitation system. Vocational rehabilitation can be an integral part of the rehabilitation process for all mental health clients.

A compilation of research working groups on drug utilisation across Europe

PubMed Central

2014-01-01

Background The assessment of the benefit-risk of medicines needs careful consideration concerning their patterns of utilization. Systems for the monitoring of medicines consumption have been established in many European countries, and several international groups have identified and described them. No other compilation of European working groups has been published. As part of the PROTECT project, as a first step in searching for European data sources on the consumption of five selected groups of medicines, we aimed to identify and describe the main characteristics of the existing collaborative European working groups. Findings Google and bibliographic searches (PubMed) of articles containing information on databases and other sources of drug consumption data were conducted. For each working group the main characteristics were recorded. Nineteen selected groups were identified, focusing on: a) general drug utilisation (DU) research (EuroDURG, CNC, ISPE’S SIG-DUR, EURO-MED-STAT, PIPERSKA Group, NorPEN, ENCePP, DURQUIM), b) specific DU research: b.1) antimicrobial drugs (ARPAC, ESAC, ARPEC, ESGAP, HAPPY AUDIT), b.2) cardiovascular disease (ARITMO, EUROASPIRE), b.3) paediatrics (TEDDY), and b.4) mental health/central nervous system effects (ESEMeD, DRUID, TUPP/EUPoMMe). Information on their aims, methods and activities is presented. Conclusions We assembled and updated information on European working groups in DU research and in the utilisation of five selected groups of drugs for the PROTECT project. This information should be useful for academic researchers, regulatory and health authorities, and pharmaceutical companies conducting and interpreting post-authorisation and safety studies. European health authorities should encourage national research and collaborations in this important field for public health. PMID:24625054

The exact nature of episodic and working memory impairments in alcoholic Korsakoff patients (KS) remains unclear, as does the specificity of these neuropsychological deficits compared with those of non-Korsakoff alcoholics (AL). The goals of the present study were therefore to (1) specify the nature of episodic and working memory impairments in KS, (2) determine the specificity of the KS neuropsychological profile compared with the AL profile, and (3) observe the distribution of individual performances within the 2 patient groups. We investigated episodic memory (encoding and retrieval abilities, contextual memory and state of consciousness associated with memories), the slave systems of working memory (phonological loop, visuospatial sketchpad and episodic buffer) and executive functions (inhibition, flexibility, updating and integration abilities) in 14 strictly selected KS, 40 AL and 55 control subjects (CS). Compared with CS, KS displayed impairments of episodic memory encoding and retrieval, contextual memory, recollection, the slave systems of working memory and executive functions. Although episodic memory was more severely impaired in KS than in AL, the single specificity of the KS profile was a disproportionately large encoding deficit. Apart from organizational and updating abilities, the slave systems of working memory and inhibition, flexibility and integration abilities were impaired to the same extent in both alcoholic groups. However, some KS were unable to complete the most difficult executive tasks. There was only a partial overlap of individual performances by KS and AL for episodic memory and a total mixture of the 2 groups for working memory. Korsakoff's syndrome encompasses impairments of the different episodic and working memory components. AL and KS displayed similar profiles of episodic and working memory deficits, in accordance with neuroimaging investigations showing similar patterns of brain damage in both alcoholic groups.

Aligning leadership across systems and organizations to develop a strategic climate for evidence-based practice implementation.

Aarons, Gregory A; Ehrhart, Mark G; Farahnak, Lauren R; Sklar, Marisa

2014-01-01

There has been a growing impetus to bridge the gap between basic science discovery, development of evidence-based practices (EBPs), and the availability and delivery of EBPs in order to improve the public health impact of such practices. To capitalize on factors that support implementation and sustainment of EBPs, it is important to consider that health care is delivered within the outer context of public health systems and the inner context of health care organizations and work groups. Leaders play a key role in determining the nature of system and organizational contexts. This article addresses the role of leadership and actions that leaders can take at and across levels in developing a strategic climate for EBP implementation within the outer (i.e., system) and inner (i.e., organization, work group) contexts of health care. Within the framework of Edgar Schein's "climate embedding mechanisms," we describe strategies that leaders at the system, organization, and work group levels can consider and apply to develop strategic climates that support the implementation and sustainment of EBP in health care and allied health care settings.

The purpose of this study was to compare apical transportation, working-length changes, and instrumentation time by using nickel-titanium (Ni-Ti) rotary file systems (crown-down method) or stainless steel hand files (balanced-force technique) in mesiobuccal canals of extracted mandibular molars. The curvature of each canal was determined and teeth placed into three equivalent groups. Group 1 was instrumented with Sequence (Brasseler USA, Savannah, GA) rotary files, group 2 with Liberator (Miltex Inc, York, PA) rotary files, and group 3 with Flex-R (Union Broach, New York, NY) files. Pre- and postoperative radiographs were superimposed to measure loss of working length and apical transportation as shown by changes in radius of curvature and the long-axis canal angle. Sequence rotary files, Liberator rotary files, and Flex-R hand files had similar effects on apical canal transportation and changes in working length, with no significant differences detected among the 3 groups. Hand instrumentation times were longer than with either Ni-Ti rotary group, whereas the rotary NiTi groups had a higher incidence of fracture.

Twelve-hour shift systems have become more popular in industry. Survey data of shift length, shift rotation speed, self-rated sleep, satisfaction and perceived health were investigated for the associations among 599 predominantly male Finnish industrial employees. The studied forward-rotating shift systems were 12-h fast (12fast, DDNN------, n = 268), 8-h fast (8fast, MMEENN----, n = 161) and 8-h slow (8slow, MMMM-EEEE-NNNN, n = 170). Satisfaction with shift system differed between the groups (p < 0.01) after controlling for age, gender, shift work experience and self-rated stress. In the 12fast, 98% of employees were satisfied with their shift system (75% 8fast, 54% 8slow). Negative effects on sleep and alertness were rare (8%) in the 12fast group (53% 8fast, 66% 8 slow, p < 0.01) and self-reported sleep difficulties were less frequent than in the 8fast and 8slow groups (8%, 27%, 41%, respectively, p < 0.01). The self-reported average sleep duration (12fast 7:50, 8fast 7:24, 8slow 7:15, p < 0.01), and shift-specific sleep before and between morning shifts and after first night shift were longer in the 12fast group. Perceived negative effects of the current shift system on general health (12fast 4%, 8fast 30%, 8slow 41%, p < 0.001) and work-life balance (12fast 8%, 8fast 52%, 8slow 63%, p < 0.001) differed strongly between the groups. In conclusion, the perceived effects of shift work were dependent on both shift length and shift rotation speed: employees in the 12-h rapidly forward-rotating shift system were most satisfied, perceived better work-life balance and slept better than the employees in the 8fast or especially the employees in the 8-h slowly rotating systems.

Integration of workplace employee health promotion (HP) and occupational health and safety (OHS) work into organizational quality improvement systems is suggested as a way to strengthen HP and OHS activities in an organization. The aim of this article was to study what consequences integration of HP, OHS and a quality improvement system called kaizen has on the frequency and type of HP and OHS activities. A quasi-experimental study design was used where an integration of the three systems for HP, OHS respectively kaizen, was performed at six intervention units at a Swedish hospital. The remaining six units served as controls. Document analysis of all employees' written improvement suggestions (kaizen notes) during 2013 was conducted. The findings show that the intervention group had more suggestions concerning HP and OHS (n = 114) when compared with the control group (n = 78) and a greater variety of HP and OHS suggestions. In addition, only the intervention group had included HP aspects. In both groups, most kaizen notes with health consideration had a preventive focus rather than rehabilitative. The intervention, i.e. the integration of HP, OHS and kaizen work, had a favourable effect on HP and OHS work when compared with the controls. The results of the study support that this system can work in practice at hospitals. © The Author 2015. Published by Oxford University Press. All rights reserved.

It has been estimating that about 20% working persons works in the shift system. It concerns health service employees and policemen among others. The shift work causes permanent conflict "of biological clock" with required working hours. The work in the night hours is less effective, it is held with greater expensive and triggering the increased tiredness.The aim of overtaken by the authors questionnaire survey amongst the population working in shifts, was to determining the influence of the shift work on the length and the quality of the dream and the tiredness and the sleepiness during day in comparison to group working only on the day shift. The survey was conducted in the group of employees of the Health Service (30 persons) and policemen (20 persons) working in shifts. Healthy volunteers working in the system of the daily work constituted the control group (30 persons). The examination consisted of questionnaire forms which were filled in anonymously, the duration of examining one person lasted 4 weeks. Age and sex of the examined and control group were similar. In the examined period of time the number of night shift was averaged 6. During holidays 47 persons had night changes. Average time of dream was approximately 7 hours, for those who was working only at daily shift. On the following day after the night shift examined slept additionally average about 3 hours. Those who didn't work in shifts slept average 7.5 hour/24. Clinically significant sleeplessness was developed: examined group--18 persons, control group--3 persons. Amongst respondents we measured level of sleepiness during night shift using carolain scale of the sleepiness. Increase of sleepiness and decrease of activity appeared between 2:00 and 6:00 a.m. In the process of the examination a measurement of appearing the indications of exaggerated sleepiness and tiredness was also conducted using the ATS scale. The frequency of appearing was two or even three times bigger in the examined group. In examined group most common was reduction of psychophysical activity and difficulty in maintaining opened eyes. We have noted most often reduction of psychophysical activity and the problem with concentrating the eyesight on the object in the examined group. 1. The shift work is connected with a substantial effect to the clinical insomnia. 2. Insufficiency of sleep is a frequent occurrence in those who works in shifts especially having above 6 night shift monthly and also having children below 7 years.

Taxonomy of trans-Neptunian objects and Centaurs as seen from spectroscopy

NASA Astrophysics Data System (ADS)

Merlin, F.; Hromakina, T.; Perna, D.; Hong, M. J.; Alvarez-Candal, A.

2017-08-01

Context. Taxonomy of trans-Neptunian objects (TNOs) and Centaurs has been made in previous works using broadband filters in the visible and near infrared ranges. This initial investigation led to the establishment of four groups with the aim to provide the mean colors of the different classes with possible links with any physical or chemical properties. However, this taxonomy was only made with the Johnson-Cousins filter system and the ESO J, H, Ks filters combination, and any association with other filter system is not yet available. Aims: We aim to edit complete visible to near infrared taxonomy and extend this work to any possible filters system. To do this, we generate mean spectra for each individual group, from a data set of 43 spectra. This work also presents new spectra of the TNO (38628) Huya, on which aqueous alteration has been suspected, and the Centaur 2007 VH305. Methods: To generate the mean spectra for each taxonomical group, we first averaged the data for each of the four taxonomical groups and checked that spectroscopic and photometric data were consistent according to their relative errors. Results: We obtained four complete spectra corresponding to the different classes from 0.45 to 2.40 microns. Our results based on spectroscopy are in good agreements with those obtained in photometry for the bluest (BB) and reddest (RR) objects. At the contrary, no clear patterns appear for the two intermediate groups (BR and IR). Both BR and IR mean-spectra are almost intermixed, probably due to the fact that part of these objects have not always clear affiliation to one particular taxonomical group. Conclusions: We provide mean spectra that could be used to edit colors in different filters system working in this wavelength range. This work clearly establish the mean spectra of the BB and RR group while the two other groups need probably further refinement. Part of the data presented here have been performed under ESO Programmes ID 178.C-0867 and ID 091.C-0224.

In the 1993 Fall quarter, the ME 4182 design class was sponsored to study various scenarios that needed to be studied for Martian travel. The class was sponsored by NASA and there were several different design projects. The design that group three chose was an integral transport system for a Martian habitat. An integral transport system means the design had to be one that was attached to the habitat. There were several criteria that the design had to meet. Group three performed an in depth study of the Martian environment and looked at several different design ideas. The concept group three developed involved the use of kinematic linkages and the use of Martian gravity to move the habitat. The various design concepts, the criteria matrices and all other aspects that helped group three develop their design can be found in their 1993 ME 4182 design report. Now it is Winter quarter 1994 and group three is faced with another problem. The problem is building a working prototype of their Fall design. The limitations this quarter were the parts. The group had to make the prototype work with existing manufactured parts or make the parts themselves in a machine shop. The prototype was scaled down roughly about twelve times smaller than the original design. The following report describes the actions taken by group three to build a working model.

The role of NASA's Earth Science Data Systems Working Groups (ESDSWG) is to make recommendations relevant to NASA's Earth science data systems from users' experiences and community insight. Each group works independently, focusing on a unique topic. Progress of two of the 2017 Working Groups will be presented. In a single airborne field campaign, there can be several different instruments and techniques that measure the same parameter on one or more aircraft platforms. Many of these same parameters are measured during different airborne campaigns using similar or different instruments and techniques. The Airborne Composition Standard Variable Name Working Group is working to create a list of variable standard names that can be used across all airborne field campaigns in order to assist in the transition to the ICARTT Version 2.0 file format. The overall goal is to enhance the usability of ICARTT files and the search ability of airborne field campaign data. The Time Series Working Group (TSWG) is a continuation of the 2015 and 2016 Time Series Working Groups. In 2015, we started TSWG with the intention of exploring the new OGC (Open Geospatial Consortium) WaterML 2 standards as a means for encoding point-based time series data from NASA satellites. In this working group, we realized that WaterML 2 might not be the best solution for this type of data, for a number of reasons. Our discussion with experts from other agencies, who have worked on similar issues, identified several challenges that we would need to address. As a result, we made the recommendation to study the new TimeseriesML 1.0 standard of OGC as a potential NASA time series standard. The 2016 TSWG examined closely the TimeseriesML 1.0 and, in coordination with the OGC TimeseriesML Standards Working Group, identified certain gaps in TimeseriesML 1.0 that would need to be addressed for the standard to be applicable to NASA time series data. An engineering report was drafted based on the OGC Engineering Report template, describing recommended changes to TimeseriesML 1.0, in the form of use cases. In 2017, we are conducting interoperability experiments to implement the use cases and demonstrate the feasibility and suitability of these modifications for NASA and related user communities. The results will be incorporated into the existing draft engineering report.

Electrical and chemical interactions at Mars Workshop, part 1

NASA Technical Reports Server (NTRS)

1992-01-01

The Electrical and Chemical Interactions at Mars Workshop, hosted by NASA Lewis Research Center on November 19 and 20, 1991, was held with the following objectives in mind: (1) to identify issues related to electrical and chemical interactions between systems and their local environments on Mars, and (2) to recommend means of addressing those issues, including the dispatch of robotic spacecraft to Mars to acquire necessary information. The workshop began with presentations about Mars' surface and orbital environments, Space Exploration Initiative (SEI) systems, environmental interactions, modeling and analysis, and plans for exploration. Participants were then divided into two working groups: one to examine the surface of Mars; and the other, the orbit of Mars. The working groups were to identify issues relating to environmental interactions; to state for each issue what is known and what new knowledge is needed; and to recommend ways to fulfill the need. Issues were prioritized within each working group using the relative severity of effects as a criterion. Described here are the two working groups' contributions. A bibliography of materials used during the workshop and suggested reference materials is included.

Over 20% of employees in Europe work in shifts. Shift work increases the risk for chronic diseases, but a healthy lifestyle may attenuate the adverse effect of shift work. The aim of this study was to explore food and nutrient intake differences between working time groups. The participants were 1478 employees (55% of men) of an airline divided into three working time groups: day work (n=608), shift work without in-flight work (n=541) and in-flight work (n=329). Measures included laboratory tests, physical measurements, a questionnaire, and food and nutrient intake estimations by a validated 16-item food intake questionnaire. Shift working men were less likely to consume vegetables (p<0.001) and fruits (p=0.049) daily than male day and in-flight workers. In women, energy intake from saturated fat was higher among shift workers compared with day workers (12.6 vs 12.2 E%, p=0.023). In older female participants, energy intake from fat and saturated fat was higher in the shift work and in-flight work groups than in the day work group (p<0.001). In this study, shift work and working environment were associated with dietary habits, and this association was not explained by other characteristics such as workers' educational level. Shift workers' increased risk for chronic diseases should be taken into account and lifestyle counselling including advice in nutrition should be incorporated in routine occupational healthcare of shift workers.

RISM investigated alternative approaches, technologies, and communication network architectures to facilitate building the Spaceports and Ranges of the future. RISM started by document most existing US ranges and their capabilities. In parallel, RISM obtained inputs from the following: 1) NASA and NASA-contractor engineers and managers, and; 2) Aerospace leaders from Government, Academia, and Industry, participating through the Space Based Range Distributed System Working Group (SBRDSWG), many of whom are also; 3) Members of the Advanced Range Technology Working Group (ARTWG) subgroups, and; 4) Members of the Advanced Spaceport Technology Working Group (ASTWG). These diverse inputs helped to envision advanced technologies for implementing future Ranges and Range systems that builds on today s cabled and wireless legacy infrastructures while seamlessly integrating both today s emerging and tomorrow s building-block communication techniques. The fundamental key is to envision a transition to a Space Based Range Distributed Subsystem. The enabling concept is to identify the specific needs of Range users that can be solved through applying emerging communication tech

Concurrent Path Planning with One or More Humanoid Robots

A robotic system includes a controller and one or more robots each having a plurality of robotic joints. Each of the robotic joints is independently controllable to thereby execute a cooperative work task having at least one task execution fork, leading to multiple independent subtasks. The controller coordinates motion of the robot(s) during execution of the cooperative work task. The controller groups the robotic joints into task-specific robotic subsystems, and synchronizes motion of different subsystems during execution of the various subtasks of the cooperative work task. A method for executing the cooperative work task using the robotic system includes automatically grouping the robotic joints into task-specific subsystems, and assigning subtasks of the cooperative work task to the subsystems upon reaching a task execution fork. The method further includes coordinating execution of the subtasks after reaching the task execution fork.

2016-08-01

In the case of modern manufacturing systems the requirements, both according the scope and according characteristics of technical procedures are dynamically changing. This results in production system organization inability to keep up with changes in a market demand. Accordingly, there is a need for new design methods, characterized, on the one hand with a high efficiency and on the other with the adequate level of the generated organizational solutions. One of the tools that could be used for this purpose is the concept of agent systems. These systems are the tools of artificial intelligence. They allow assigning to agents the proper domains of procedures and knowledge so that they represent in a self-organizing system of an agent environment, components of a real system. The agent-based system for modelling robotic work cell should be designed taking into consideration many limitations considered with the characteristic of this production unit. It is possible to distinguish some grouped of structural components that constitute such a system. This confirms the structural complexity of a work cell as a specific production system. So it is necessary to develop agents depicting various aspects of the work cell structure. The main groups of agents that are used to model a robotic work cell should at least include next pattern representatives: machine tool agents, auxiliary equipment agents, robots agents, transport equipment agents, organizational agents as well as data and knowledge bases agents. In this way it is possible to create the holarchy of the agent-based system.

2000-01-01

The GEWEX Cloud System Study (GCSS, GEWEX is the Global Energy and Water Cycle Experiment) is a community activity aiming to promote development of improved cloud parameterizations for application in the large-scale general circulation models (GCMs) used for climate research and for numerical weather prediction. The GCSS strategy is founded upon the use of cloud-system models (CSMs). These are "process" models with sufficient spatial and temporal resolution to represent individual cloud elements, but spanning a wide range of space and time scales to enable statistical analysis of simulated cloud systems. GCSS also employs single-column versions of the parametric cloud models (SCMs) used in GCMs. GCSS has working groups on boundary-layer clouds, cirrus clouds, extratropical layer cloud systems, precipitating deep convective cloud systems, and polar clouds.

2010-05-25

The activity of Phase I of the Waste Management Working Group under the United States - Japan Joint Nuclear Energy Action Plan started in 2007. The US-Japan JNEAP is a bilateral collaborative framework to support the global implementation of safe, secure, and sustainable, nuclear fuel cycles (referred to in this document as fuel cycles). The Waste Management Working Group was established by strong interest of both parties, which arise from the recognition that development and optimization of waste management and disposal system(s) are central issues of the present and future nuclear fuel cycles. This report summarizes the activity of themore » Waste Management Working Group that focused on consolidation of the existing technical basis between the U.S. and Japan and the joint development of a plan for future collaborative activities. Firstly, the political/regulatory frameworks related to nuclear fuel cycles in both countries were reviewed. The various advanced fuel cycle scenarios that have been considered in both countries were then surveyed and summarized. The working group established the working reference scenario for the future cooperative activity that corresponds to a fuel cycle scenario being considered both in Japan and the U.S. This working scenario involves transitioning from a once-through fuel cycle utilizing light water reactors to a one-pass uranium-plutonium fuel recycle in light water reactors to a combination of light water reactors and fast reactors with plutonium, uranium, and minor actinide recycle, ultimately concluding with multiple recycle passes primarily using fast reactors. Considering the scenario, current and future expected waste streams, treatment and inventory were discussed, and the relevant information was summarized. Second, the waste management/disposal system optimization was discussed. Repository system concepts were reviewed, repository design concepts for the various classifications of nuclear waste were summarized, and the factors to consider in repository design and optimization were then discussed. Japan is considering various alternatives and options for the geologic disposal facility and the framework for future analysis of repository concepts was discussed. Regarding the advanced waste and storage form development, waste form technologies developed in both countries were surveyed and compared. Potential collaboration areas and activities were next identified. Disposal system optimization processes and techniques were reviewed, and factors to consider in future repository design optimization activities were also discussed. Then the potential collaboration areas and activities related to the optimization problem were extracted.« less

The IEEE Storage System Standards Working Group (SSSWG) has developed the Reference Model for Open Storage Systems Interconnection, Mass Storage System Reference Model Version 5. This document, provides the framework for a series of standards for application and user interfaces to open storage systems. More recently, the SSSWG has been developing Application Programming Interfaces (APIs) for the individual components defined by the model. The API for the Physical Volume Repository is the most fully developed, but work is being done on APIs for the Physical Volume Library and for the Mover also. The SSSWG meets every other month, and meetings are open to all interested parties. The Physical Volume Repository (PVR) is responsible for managing the storage of removable media cartridges and for mounting and dismounting these cartridges onto drives. This document describes a model which defines a Physical Volume Repository, and gives a brief summary of the Application Programming Interface (API) which the IEEE Storage Systems Standards Working Group (SSSWG) is proposing as the standard interface for the PVR.

A collaborative design method to support integrated care. An ICT development method containing continuous user validation improves the entire care process and the individual work situation

Scandurra, Isabella; Hägglund, Maria

2009-01-01

Introduction Integrated care involves different professionals, belonging to different care provider organizations and requires immediate and ubiquitous access to patient-oriented information, supporting an integrated view on the care process [1]. Purpose To present a method for development of usable and work process-oriented information and communication technology (ICT) systems for integrated care. Theory and method Based on Human-computer Interaction Science and in particular Participatory Design [2], we present a new collaborative design method in the context of health information systems (HIS) development [3]. This method implies a thorough analysis of the entire interdisciplinary cooperative work and a transformation of the results into technical specifications, via user validated scenarios, prototypes and use cases, ultimately leading to the development of appropriate ICT for the variety of occurring work situations for different user groups, or professions, in integrated care. Results and conclusions Application of the method in homecare of the elderly resulted in an HIS that was well adapted to the intended user groups. Conducted in multi-disciplinary seminars, the method captured and validated user needs and system requirements for different professionals, work situations, and environments not only for current work; it also aimed to improve collaboration in future (ICT supported) work processes. A holistic view of the entire care process was obtained and supported through different views of the HIS for different user groups, resulting in improved work in the entire care process as well as for each collaborating profession [4].

[The impact of harmful occupational factors on the morbidity rate of workers of the railway-car repair plant].

Sudeikina, N A; Kurenkova, G V; Lemeshevskaya, E P

The rail transport is the one of the leading sectors of the national economy. More than 50% of the employees of the enterprises of the railway complex work under the unfavourable impact of hazardous and dangerous substances and occupational factors. In the literature issues of working conditions and health of employees of railway carrepairing plant are hardly highlighted. The aim of the study is the evaluation of the morbidity rate shaped under the influence of harmful occupational factors for the elaboration of preventive measures. In the work there were used generally accepted methods of hygienic studies, analysis of morbidity rate with temporary disability (TD), according to records of periodic medical examinations, occupational prevalence. The railway car-repairing plant was established to be characterized by the complex of harmful factors of the working environment and labor process: noise, local vibration, industrial aerosols of complex composition, chemicals, low light, hardness of the labor process. The levels of incidence with temporal disability in the studied groups, depending on the work seniority in the harmful labor conditions, significantly decrease with the experience from 5 to 9 years and increase with the experience more than 10 years. Executed in-depth analysis as of the both morbidity rate and TD, as well results of periodic medical examinations of workers of main shops shows that overall indices of the morbidity rate and TD are significantly higher than in the comparison group; levels of the morbidity rate and TD in the observed groups significantly decline depending on the length of service in hazardous working conditions with a length of the experience offrom 5 to 9 years and increase with the increase in the length of experience of 10 years or more. In the structure of morbidity and TD leading positions are occupied by diseases of the respiratory system, musculoskeletal system and connective tissue, circulatory system and digestive system, diseases of the eye and its appendages. The health damage risk coefficients in the studied groups of workers and the average losses of working time due to the morbidity with TD per 1 employee in all shops are higher than those in the comparison group. The level of the occupational morbidity rate is very low. Harmful working conditions contribute to the development of general and occupationally related diseases.

The physical work environment and end-user requirements: Investigating marine engineering officers' operational demands and ship design.

Physical environments influence how individuals perceive a space and behave within it. Previous research has revealed deficiencies in ship engine department work environments, and their impact on crew productivity, health and wellbeing. Connect operational task demands to pragmatic physical design and layout solutions by implementing a user-centric perspective. Three focus groups, each consisting of three marine engineers participated in this study. Focus groups were divided into two sessions: first, to investigate the end-user's operational requirements and their relationship with ship physical design and layout. Second, criteria formulated from group discussions were applied to a ship design case study. All focus group sessions were audio recorded and transcribed verbatim. The data were analyzed using Grounded Theory. Design choices made in a ships general arrangement were described to inherently influence how individuals and teams are able to function within the system. Participants detailed logistical relationships between key areas, stressing that the work environment and physical linkages must allow for flexibility of work organization and task execution. Traditional engine control paradigms do not allow effective mitigation of traditional engine department challenges. The influence of technology and modernization of ship systems can facilitate improvement of physical environments and work organization if effectively utilized.

A century of work teams in the Journal of Applied Psychology.

Mathieu, John E; Hollenbeck, John R; van Knippenberg, Daan; Ilgen, Daniel R

2017-03-01

Work groups are a vital link between individuals and organizations. Systematic psychological research on the nature and effects of work groups dates back at least to the Hawthorne studies of the 1920s and 1930s. Yet little to none of this work appeared in the Journal of Applied Psychology until the 1950s when groups were treated primarily as foils against which to compare the performance of individuals. From the 1990s to the present, the volume of research and the nature of topics addressing work group/teams expanded significantly. The authors review the evolution of team research over the past century with a particular focus on that which has appeared in this journal. They chronicle the shift from a focus on individuals within teams, or on individual versus team comparisons, to a focus on the team itself and larger systems of teams. They describe the major outcomes studied within this literature, and how they relate to the nature of team tasks and structures. Further, the authors consider the roles of team members' characteristics and composition, and team dynamics in terms of processes and emergent states. They close with a call for future research that models dynamic team relationships in context and as they operate in complex systems. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

A Follow-Up Study on Return to Work in the Year After Reporting an Occupational Injury Stratified by Outcome of the Workers' Compensation System.

PubMed

Rudbeck, Marianne; Johansen, Jens Peter; Omland, Øyvind

2018-06-01

The aim of this study was to compare return rates to work between different groups according to the decision from the workers' compensation. Register data on disability benefits were used to describe return rates to work in Kaplan-Meier curves and association with decision on compensation claims. Disability benefits were granted by the municipalities independently of any compensation claim if sick-listed. Claimants with ongoing claims were the group with the largest proportion remaining on disability benefits. Claimants with rejected claims returned to work at the same rate (occupational disease) or slower (industrial accident) than claimants with recognized claim without compensation the subsequent year and at a faster rate after decision. Compensation claims and proceedings of the workers' compensation system probably increase time to return to work; other factors such as health and social difficulties, however, may explain some of these differences.

The prospect of biological attacks is a growing strategic threat. Covert aerosol attacks inside a building are of particular concern. In the summer of 2005, the Center for Biosecurity of the University of Pittsburgh Medical Center convened a Working Group to determine what steps could be taken to reduce the risk of exposure of building occupants after an aerosol release of a biological weapon. The Working Group was composed of subject matter experts in air filtration, building ventilation and pressurization, air conditioning and air distribution, biosecurity, building design and operation, building decontamination and restoration, economics, medicine, public health, and public policy. The group focused on functions of the heating, ventilation, and air conditioning systems in commercial or public buildings that could reduce the risk of exposure to deleterious aerosols following biological attacks. The Working Group's recommendations for building owners are based on the use of currently available, off-the-shelf technologies. These recommendations are modest in expense and could be implemented immediately. It is also the Working Group's judgment that the commitment and stewardship of a lead government agency is essential to secure the necessary financial and human resources and to plan and build a comprehensive, effective program to reduce exposure to aerosolized infectious agents in buildings.

Unprotected sexual intercourse exposes the female genital tract (FGT) to semen-derived antigens, which leads to a proinflammatory response. Studies have shown that this postcoital inflammatory response can lead to recruitment of activated T cells to the FGT, thereby increasing risk of HIV infection. The purpose of this study was to evaluate the impact of sex work on activation and memory phenotypes of peripheral T cells among female sex workers (FSW) from Nairobi, Kenya. Thirty FSW were recruited from the Pumwani Sex Workers Cohort, 10 in each of the following groups: HIV-exposed seronegative (at least 7 years in active sex work), HIV positive, and New Negative (HIV negative, less than 3 years in active sex work). Blood was obtained at three different phases (active sex work, abstinence from sex work-sex break, and following resumption of sex work). Peripheral blood mononuclear cells were isolated and stained for phenotypic markers (CD3, CD4, CD8, and CD161), memory phenotype markers (CD45RA and CCR7), activation markers (CD69, HLA-DR, and CD95), and the HIV coreceptor (CCR5). T-cell populations were compared between groups. In HIV-positive women, CD8+CCR5+ T cells declined at the sex break period, while CD4+CD161+ T cells increased when returning to sex work. All groups showed no significant changes in systemic T-cell activation markers following the interruption of sex work, however, significant reductions in naive CD8+ T cells were noted. For each of the study points, HIV positives had higher effector memory and CD8+CD95+ T cells and lower naive CD8+ T cells than the HIV-uninfected groups. Interruption of sex work had subtle effects on systemic T-cell memory phenotypes.

Does the medium matter? The interaction of task type and technology on group performance and member reactions.

The authors investigated the hypothesis that as group tasks pose greater requirements for member interdependence, communication media that transmit more social context cues will foster group performance and satisfaction. Seventy-two 3-person groups of undergraduate students worked in either computer-mediated or face-to-face meetings on 3 tasks with increasing levels of interdependence: an idea-generation task, an intellective task, and a judgment task. Results showed few differences between computer-mediated and face-to-face groups in the quality of the work completed but large differences in productivity favoring face-to-face groups. Analysis of productivity and of members' reactions supported the predicted interaction of tasks and media, with greater discrepancies between media conditions for tasks requiring higher levels of coordination. Results are discussed in terms of the implications of using computer-mediated communications systems for group work.

Supporting the development and sustenance of a diverse geoscience workforce and improving Earth system education for the full diversity of students are important goals for our community. There are numerous established programs and many new efforts beginning. However, these efforts can become more powerful if dissemination of opportunities, effective practices, and web-based resources enable synergies to develop throughout our community. The Digital Library for Earth System Education (DLESE; www.dlese.org) has developed a working group and a website to support these goals. The DLESE Diversity Working Group provides an open, virtual community for those interested in enhancing diversity in the geosciences. The working group has focused its initial effort on 1) creating a geoscience community engaged in supporting increased diversity that builds on and is integrated with work taking place in other venues; 2) developing a web resource designed to engage and support members of underrepresented groups in learning about the Earth; and 3) assisting in enhancing DLESE collections and services to better support learning experiences of students from underrepresented groups. You are invited to join the working group and participate in these efforts. The DLESE diversity website provides a mechanism for sharing information and resources. Serving as a community database, the website provides a structure in which community members can post announcements of opportunities, information on programs, and links to resources and services. Information currently available on the site includes links to professional society activities; mentoring opportunities; grant, fellowship, employment, and internship opportunities for students and educators; information on teaching students from underrepresented groups; and professional development opportunities of high interest to members of underrepresented groups. These tools provide a starting point for developing a community wide effort to enhance diversity in the geosciences that builds on our collective experiences, knowledge and resources and the work that is taking place in communities around us.

Psychosocial stress at work not only affects the healthy working population, but also workers with chronic diseases. We aimed to investigate the psychosocial work stress levels in patients with systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). A cross-sectional study applied the Effort-Reward Imbalance (ERI) questionnaire - an internationally established instrument that measures work stress - to patients with SLE and RA who were capable of work and to a group of controls without these diseases. Participants were recruited through rheumatologists in private practices, hospitals, and from self-help groups by personal communication, paper-based flyers, and online advertisements. Because very few studies tested the ERI's applicability in patient groups, with a lack of evidence in patients with inflammatory rheumatic diseases, internal consistency and construct validity of the ERI measure were evaluated. Data came from 270 patients with RA and 247 with SLE, and 178 controls. Patients showed elevated psychosocial stress at work compared to controls. Across the total sample and all groups, satisfactory internal consistencies of the scales effort, reward, and overcommitment were obtained (Cronbach's alpha coefficients > 0.70), and confirmatory factor analysis replicated the theoretical structure of the ERI model (goodness-of-fit index > 0.80). We found elevated psychosocial stress at work in patients with SLE and RA compared to controls by applying the ERI model. Despite some heterogeneity in the sample, we achieved satisfactory psychometric properties of the ERI questionnaire. Our results suggest that the ERI questionnaire is a psychometrically useful tool to be implemented in epidemiological studies of employed patients with SLE and RA.

To report on the progress of an ongoing research collaboration on magnetic resonance imaging (MRI) in juvenile idiopathic arthritis (JIA) and describe the proceedings of a meeting, held prior to Outcome Measures in Rheumatology (OMERACT) 12, bringing together the OMERACT MRI in JIA working group and the Health-e-Child radiology group. The goal of the meeting was to establish agreement on scoring definitions, locations, and scales for the assessment of MRI of patients with JIA for both large and small joints. The collaborative work process included premeeting surveys, presentations, group discussions, consensus on scoring methods, pilot scoring, conjoint review, and discussion of a future research agenda. The meeting resulted in preliminary statements on the MR imaging protocol of the JIA knee and wrist and determination of the starting point for development of MRI scoring systems based on previous studies. It was also considered important to be descriptive rather than explanatory in the assessment of MRI in JIA (e.g., "thickening" instead of "hypertrophy"). Further, the group agreed that well-designed calibration sessions were warranted before any future scoring exercises were conducted. The combined efforts of the OMERACT MRI in JIA working group and Health-e-Child included the assessment of currently available material in the literature and determination of the basis from which to start the development of MRI scoring systems for both the knee and wrist. The future research agenda for the knee and wrist will include establishment of MRI scoring systems, an atlas of MR imaging in healthy children, and MRI protocol requisites.

The use of dental computer-aided design/computer-aided manufacturing (CAD/CAM) restoration is rapidly increasing. This study was performed to evaluate the marginal and internal cement thickness and the adhesive gap of internal cavities comprising CAD/CAM materials using two digital impression acquisition methods and micro-computed tomography. Images obtained by a single-image acquisition system (Bluecam Ver. 4.0) and a full-color video acquisition system (Omnicam Ver. 4.2) were divided into the BL and OM groups, respectively. Silicone impressions were prepared from an ISO-standard metal mold, and CEREC Stone BC and New Fuji Rock IMP were used to create working models (n=20) in the BL and OM groups (n=10 per group), respectively. Individual inlays were designed in a conventional manner using designated software, and all restorations were prepared using CEREC inLab MC XL. These were assembled with the corresponding working models used for measurement, and the level of fit was examined by three-dimensional analysis based on micro-computed tomography. Significant differences in the marginal and internal cement thickness and adhesive gap spacing were found between the OM and BL groups. The full-color movie capture system appears to be a more optimal restoration system than the single-image capture system.

Flattening the organization: implementing self-directed work groups.

Brandon, G M

In response to tremendous growth of managed care and threats to financial stability and job security, the Greater Baltimore Medical Center (GBMC) restructured itself into independent business units. The radiology department at GBMC resolved to reduce cost per unit-of-service, improve service, determine optimal staffing levels and reduce the number of layers of organization. It was decided to achieve those goals by implementing self-directed work groups. Staff buy-in was critical to success of the project. To begin, the staff was educated intensively about current trends in healthcare, managed care and potential changes in the job market. The radiology department was allowed to reduce the size of its staff through attrition and worked hard to focus staff concern on the impact each individual could have on the bottom line and the resultant effect on job security. Self-directed work groups were designed on a matrix that used small "service teams" in combinations to form larger "work groups." Actual work and daily activities occur at the service team level; information exchange and major decisions occue at the work group level. Seventeen months after beginning the project and 10 months after implementation, the organization has flattened, staff members have adjusted well to new roles, there have been no lay-offs, and the matrix system of small and large groups have proved particularly valuable.

Interference control in working memory: comparing groups of children with atypical development.

Palladino, Paola; Ferrari, Marcella

The study aimed to test whether working memory deficits in children at risk of Learning Disabilities (LD) and/or attention deficit/hyperactivity disorder (ADHD) can be attributed to deficits in interference control, thereby implicating prefrontal systems. Two groups of children known for showing poor working memory (i.e., children with poor comprehension and children with ADHD) were compared to a group of children with specific reading decoding problems (i.e., having severe problems in phonological rather than working memory) and to a control group. All children were tested with a verbal working memory task. Interference control of irrelevant items was examined by a lexical decision task presented immediately after the final recall in about half the trials, selected at random. The interference control measure was therefore directly related to working memory performance. Results confirmed deficient working memory performance in poor comprehenders and children at risk of ADHD + LD. More interestingly, this working memory deficit was associated with greater activation of irrelevant information than in the control group. Poor decoders showed more efficient interference control, in contrast to poor comprehenders and ADHD + LD children. These results indicated that interfering items were still highly accessible to working memory in children who fail the working memory task. In turn, these findings strengthen and clarify the role of interference control, one of the most critical prefrontal functions, in working memory.

1989-01-01

The outcome is documented of a Flight-Critical Digital Systems Technology Workshop held at NASA-Langley December 13 to 15 1988. The purpose of the workshop was to elicit the aerospace industry's view of the issues which must be addressed for the practical realization of flight-critical digital systems. The workshop was divided into three parts: an overview session; three half-day meetings of seven working groups addressing aeronautical and space requirements, system design for validation, failure modes, system modeling, reliable software, and flight test; and a half-day summary of the research issues presented by the working group chairmen. Issues that generated the most consensus across the workshop were: (1) the lack of effective design and validation methods with support tools to enable engineering of highly-integrated, flight-critical digital systems, and (2) the lack of high quality laboratory and field data on system failures especially due to electromagnetic environment (EME).

Objective: We clarified the relationship between the degree of subjective fatigue, sleep, and physical activity among nurses working 16-hour night shifts in a rotating two-shift system. Materials and Methods: We investigated 15 nurses who were surveyed regarding their individual attributes, physical activity level (consumed calories), hours of sleep, sleep efficiency, sleep onset latency, sleep diary, and subjective symptoms. Nurses wore a Fitbit One (Fitbit Inc., San Francisco, CA, USA) for 7 consecutive days to measure sleep and physical activity. Results: Results were analyzed for nine participants, excluding those who withdrew or had missing data. The years of nursing experience, nurses’ age, and the length of nocturnal awakening time of the high fatigue group were significantly longer than of the low fatigue group (p < .05). Years of nursing experience in the affiliated department of the high fatigue group was significantly shorter than of low fatigue group (p < .05). The number of nightshifts during the survey period was significantly higher in the high fatigue group than in the low fatigue group. Fatigue after work and body mass index (r = 0.46, p < .001), consumed calories (r = 0.30, p < .05), bedtime (r = –0.36, p < .05), and hours of sleep (r = –0.37, p < .01) were significantly correlated; however, the sleep indices were not correlated. Conclusion: We clarified that the degree of fatigue in nurses working 16-hour night shifts in a rotating two-shift system was related to individual factors, such as age, years of nursing experience, years of nursing experience in the affiliated department, number of nightshifts, and length of nocturnal awakening time. Nurses with greater fatigue had significant differences in their bedtime on days off and work days, which suggests that sleep rhythm may also affect fatigue.

Background Encoding and maintenance of information in working memory, followed by internal manipulation of that information for planning adaptive behavior, are two key components of working-memory systems. Both processes have been reported to be impaired in schizophrenia, but few studies have directly compared the relative severity of these abnormalities, or the degree to which manipulation deficits might be secondary to alterations in maintenance processes. Method Clinically stable schizophrenia patients (n=25) and a demographically similar healthy comparison group (n=24) were administered a verbal span task with three levels of working-memory load. Maintenance was assessed using sequential position questions. Manipulation processes were assessed by requiring comparison of the relative sequential position of test items, which entailed simultaneous serial search strategies regarding item order. Results Both groups showed reduced accuracy and increased reaction time for manipulation compared with maintenance processing. There were significant patient impairments across working-memory loads. There was no differential deficit in manipulation processing, and effect sizes of relative deficit in the patient group were higher for maintenance than manipulation processing. Conclusions The strong correlation for maintenance and manipulation deficits suggest that impairments in the ability to internally manipulate information stored in working-memory systems are not greater than alterations in the encoding and maintaining of information in working memory and that disturbances in maintenance processing may contribute to deficits in higher-order working-memory operations.

This article provides a review of some of the work done in the area of knowledge-based systems for strategic planning. Since 1985, with the founding of the Center for Knowledge-based Systems for Business Management, the project has focused on developing knowledge-based systems (KBS) based on these models. In addition, the project also involves developing a variety of computer and non-computer methods and techniques for assisting both technical and non-technical managers and individuals to do decision modelling and KBS development. This paper presents a summary of one segment of the project: a description of integrative groupware useful in strategic planning. The work described here is part of an ongoing research project. As part of this project, for example, over 200 non-technical and technical business managers, most of them working full-time during the project, developed over 160 KBS prototype systems in conjunction with MBA course in strategic planning and management decision making. Based on replies to a survey of this test group, 28 per cent of the survey respondents reported their KBS were used at work, 21 per cent reportedly received promotions, pay rises or new jobs based on their KBS development work, and 12 per cent reported their work led to participation in other KBS development projects at work. All but two of the survey respondents reported that their work on the KBS development project led to a substantial increase in their job knowledge or performance.

Multiple system atrophy (MSA) is a rare neurodegenerative disorder with substantial knowledge gaps despite recent gains in basic and clinical research. In order to make further advances, concerted international collaboration is vital. In 2014, an international meeting involving leaders in the field and MSA advocacy groups was convened in Las Vegas, Nevada, to identify critical research areas where consensus and progress was needed to improve understanding, diagnosis, and treatment of the disease. Eight topic areas were defined: pathogenesis, preclinical modeling, target identification, endophenotyping, clinical measures, imaging biomarkers, nonimaging biomarkers, treatments/trial designs, and patient advocacy. For each topic area, an expert served as a working group chair and each working group developed priority-ranked research recommendations with associated timelines and pathways to reach the intended goals. In this report, each groups' recommendations are provided. Copyright © 2017 American Academy of Neurology.

2010-01-30

Concern that underfunded and weak health systems are impeding the achievement of the health Millennium Development Goals in low-income countries led to the creation of a High Level Taskforce on Innovative International Financing for Health Systems in September, 2008. This report summarises the key challenges faced by the Taskforce and its Working Groups. Working Group 1 examined the constraints to scaling up and costs. Challenges included: difficulty in generalisation because of scarce and context-specific health-systems knowledge; no consensus for optimum service-delivery approaches, leading to wide cost differences; no consensus for health benefits; difficulty in quantification of likely efficiency gains; and challenges in quantification of the financing gap owing to uncertainties about financial commitments for health. Working Group 2 reviewed the different innovative mechanisms for raising and channelling funds. Challenges included: variable definitions of innovative finance; small evidence base for many innovative finance mechanisms; insufficient experience in harmonisation of global health initiatives; and inadequate experience in use of international investments to improve maternal, newborn, and child health. The various mechanisms reviewed and finally recommended all had different characteristics, some focusing on specific problems and some on raising resources generally. Contentious issues included the potential role of the private sector, the rights-based approach to health, and the move to results-based aid. The challenges and disagreements that arose during the work of the Taskforce draw attention to the many issues facing decision makers in low-income countries. International donors and recipient governments should work together to improve the evidence base for strengthening health systems, increase long-term commitments, and improve accountability through transparent and inclusive national approaches.

2014-01-01

The main study objective was to investigate the effect of interactive television-based cognitive training on cognitive performance of 119 healthy older adults, aged 60–87 years. Participants were randomly allocated to a cognitive training group or to an active control group in a single-blind controlled two-group design. Before and after training interactive television cognitive performance was assessed on well validated tests of fluid, higher-order ability, and system usability was evaluated. The participants in the cognitive training group completed a television-based cognitive training programme, while the participants in the active control group completed a TV-based programme of personally benefiting activities. Significant improvements were observed in well validated working memory and executive function tasks in the cognitive training but not in the control group. None of the groups showed statistically significant improvement in life satisfaction score. Participants' reports of “adequate” to “high” system usability testify to the successful development and implementation of the interactive television-based system and compliant cognitive training contents. The study demonstrates that cognitive training delivered by means of an interactive television system can generate genuine cognitive benefits in users and these are measurable using well-validated cognitive tests. Thus, older adults who cannot use or afford a computer can easily use digital interactive television to benefit from advanced software applications designed to train cognition. PMID:24992187

RELAV - RELIABILITY/AVAILABILITY ANALYSIS PROGRAM

NASA Technical Reports Server (NTRS)

Bowerman, P. N.

1994-01-01

RELAV (Reliability/Availability Analysis Program) is a comprehensive analytical tool to determine the reliability or availability of any general system which can be modeled as embedded k-out-of-n groups of items (components) and/or subgroups. Both ground and flight systems at NASA's Jet Propulsion Laboratory have utilized this program. RELAV can assess current system performance during the later testing phases of a system design, as well as model candidate designs/architectures or validate and form predictions during the early phases of a design. Systems are commonly modeled as System Block Diagrams (SBDs). RELAV calculates the success probability of each group of items and/or subgroups within the system assuming k-out-of-n operating rules apply for each group. The program operates on a folding basis; i.e. it works its way towards the system level from the most embedded level by folding related groups into single components. The entire folding process involves probabilities; therefore, availability problems are performed in terms of the probability of success, and reliability problems are performed for specific mission lengths. An enhanced cumulative binomial algorithm is used for groups where all probabilities are equal, while a fast algorithm based upon "Computing k-out-of-n System Reliability", Barlow & Heidtmann, IEEE TRANSACTIONS ON RELIABILITY, October 1984, is used for groups with unequal probabilities. Inputs to the program include a description of the system and any one of the following: 1) availabilities of the items, 2) mean time between failures and mean time to repairs for the items from which availabilities are calculated, 3) mean time between failures and mission length(s) from which reliabilities are calculated, or 4) failure rates and mission length(s) from which reliabilities are calculated. The results are probabilities of success of each group and the system in the given configuration. RELAV assumes exponential failure distributions for reliability calculations and infinite repair resources for availability calculations. No more than 967 items or groups can be modeled by RELAV. If larger problems can be broken into subsystems of 967 items or less, the subsystem results can be used as item inputs to a system problem. The calculated availabilities are steady-state values. Group results are presented in the order in which they were calculated (from the most embedded level out to the system level). This provides a good mechanism to perform trade studies. Starting from the system result and working backwards, the granularity gets finer; therefore, system elements that contribute most to system degradation are detected quickly. RELAV is a C-language program originally developed under the UNIX operating system on a MASSCOMP MC500 computer. It has been modified, as necessary, and ported to an IBM PC compatible with a math coprocessor. The current version of the program runs in the DOS environment and requires a Turbo C vers. 2.0 compiler. RELAV has a memory requirement of 103 KB and was developed in 1989. RELAV is a copyrighted work with all copyright vested in NASA.

Of the 18 colleges/universities being supported by NASA through USRA, 10 colleges/universities are MSIs. While there is recognition of the need for Earth system science courses, minors and degree programs by NASA and other agencies, within MSIs, a central challenge is how to provide a vision of the future opportunities in ESS and STEM disciplines that attracts and motivates students to these studies. Students need career guidance, role models and mentoring to encourage entry into STEM in general, and Earth system science in particular. Then there is the question of how to bring interested faculty together in institutions to form a critical mass that would forego the breadth and depth of disciplinary interests to undertake the development of multi/cross and interdisciplinary courses, minors and degree programs in ESS. Within the ESSE21 Diversity Working Group, the question has been raised as to how will MSIs ever be mainstream participants in ESS without teaching and engaging in research in remote sensing, modeling of the Earth's climate system and other like endeavors. Two other related questions raised within the Working Group are what are the long-term objectives of MSI adoption of ESS and what course corrections are needed to make ESS viable at MSIs. Within these considerations there are unresolved questions concerning the need and availability of resources from NASA, other agencies and local institutions. Apart from these larger considerations, efforts are underway within the ESSE21 Program that provide for sharing of resources among participants, organization of and access to materials that already exist, online resources, course outlines and successful listings for online resources by topics for particular courses and subject areas. The Lesson Learned Working Group, as well as the program office continue with efforts in organization of the resources to foster availability and utilization. Then there is the emphasis on educational assessment, formative, ongoing and summative by the Evaluation Working Group. These challenges, questions and Working Group activities will be briefly reviewed in relation to the collaborative development of Earth System Science and STEM education within ESSE21 and its current focus on MSIs.

Lessons Learned From the Development, Operation, and Review of Mechanical Systems on the Space Shuttle, International Space Station, and Payloads

NASA Technical Reports Server (NTRS)

Dinsel, Alison; Jermstad, Wayne; Robertson, Brandan

2006-01-01

The Mechanical Design and Analysis Branch at the Johnson Space Center (JSC) is responsible for the technical oversight of over 30 mechanical systems flying on the Space Shuttle Orbiter and the International Space Station (ISS). The branch also has the responsibility for reviewing all mechanical systems on all Space Shuttle and International Space Station payloads, as part of the payload safety review process, through the Mechanical Systems Working Group (MSWG). These responsibilities give the branch unique insight into a large number of mechanical systems, and problems encountered during their design, testing, and operation. This paper contains narrative descriptions of lessons learned from some of the major problems worked on by the branch during the last two years. The problems are grouped into common categories and lessons learned are stated.

The Thermal Control Working Group limited its evaluation to issues associated with Earth orbiting and planetary spacecraft with power levels up to 50 kW. It was concluded that the space station technology is a necessary precursor but does not meet S/C 2000 needs (life, high heat flux, long term cryogenics, and survivability). Additional basic and applied research are required (fluid/materials compatibility and two phase system modeling). Scaling, the key issue, must define accelerated life test criteria. The two phase systems require 0g to 1 g correlation. Additional ground test beds are required and combined space environment tests of materials.

Wiser, Ralph S.; Valencia, Matthew J

Los Alamos National Laboratory states that its mission is “To solve national security challenges through scientific excellence.” The Science Undergraduate Laboratory Internship (SULI) programs exists to engage undergraduate students in STEM work by providing opportunity to work at DOE facilities. As an undergraduate mechanical engineering intern under the SULI program at Los Alamos during the fall semester of 2016, I had the opportunity to contribute to the mission of the Laboratory while developing skills in a STEM discipline. I worked with Technology Applications, an engineering group that supports non-proliferation, counter terrorism, and emergency response missions. This group specializes in toolmore » design, weapons engineering, rapid prototyping, and mission training. I assisted with two major projects during my appointment Los Alamos. The first was a thermal source transportation unit, intended to safely contain a nuclear thermal source during transit. The second was a soil drying unit for use in nuclear postblast field sample collection. These projects have given me invaluable experience working alongside a team of professional engineers. Skills developed include modeling, simulation, group design, product and system design, and product testing.« less

Trimble, Jay; Wales, Roxana; Gossweiler, Rich

2003-01-01

This chapter describes the ongoing process by which a multidisciplinary group at NASA's Ames Research Center is designing and implementing a large interactive work surface called the MERBoard Collaborative Workspace. A MERBoard system involves several distributed, large, touch-enabled, plasma display systems with custom MERBoard software. A centralized server and database back the system. We are continually tuning MERBoard to support over two hundred scientists and engineers during the surface operations of the Mars Exploration Rover Missions. These scientists and engineers come from various disciplines and are working both in small and large groups over a span of space and time. We describe the multidisciplinary, human-centered process by which this h4ERBoard system is being designed, the usage patterns and social interactions that we have observed, and issues we are currently facing.

MAINTENANCE MANAGEMENT ACCOUNTING SYSTEM OF WASTE WATER DISPOSAL SYSTEMS

NASA Astrophysics Data System (ADS)

Hori, Michihiro; Tsuruta, Takashi; Kaito, Kiyoyuki; Kobayashi, Kiyoshi

Sewage works facilities consist of various assets groups. And there are many kinds of financial resources. In order to optimize the maintenance plan, and to secure the stability and sustainability of sewage works management, it is necessary to carry out financial simulation based on the life-cycle cost analysis. Furthermore, it is important to develop management accounting system that is interlinked with the financial accounting system, because many sewage administration bodies have their financial accounting systems as public enterprises. In this paper, a management accounting system, which is designed to provide basic information for asset management of sewage works facilities, is presented. Also the applicability of the management accounting system presented in this paper is examined through financial simulations.

Standardized cognitive tests and functional magnetic resonance imaging (fMRI) studies of systemic lupus erythematosus (SLE) patients demonstrate deficits in working memory and executive function. These neurobehavioral abnormalities are not well studied in antiphospholipid syndrome, which may occur independently of or together with SLE. This study compares an fMRI paradigm involving motor skills, working memory, and executive function in SLE patients without antiphospholipid antibody (aPL) (the SLE group), aPL-positive non-SLE patients (the aPL-positive group), and controls. Brain MRI, fMRI, and standardized cognitive assessment results were obtained from 20 SLE, 20 aPL-positive, and 10 healthy female subjects with no history of neuropsychiatric abnormality. Analysis of fMRI data showed no differences in performance across groups on bilateral motor tasks. When analysis of variance was used, significant group differences were found in 2 executive function tasks (word generation and word rhyming) and in a working memory task (N-Back). Patients positive for aPL demonstrated higher activation in bilateral frontal, temporal, and parietal cortices compared to controls during working memory and executive function tasks. SLE patients also demonstrated bilateral frontal and temporal activation during working memory and executive function tasks. Compared to controls, both aPL-positive and SLE patients had elevated cortical activation, primarily in the frontal lobes, during tasks involving working memory and executive function. These findings are consistent with cortical overactivation as a compensatory mechanism for early white matter neuropathology in these disorders. © 2016, American College of Rheumatology.

Musculoskeletal disorders (MSDs) are a frequent cause of work disability, accounting for productivity losses in industrialized societies equivalent to 1.3% of the U.S. gross national product. To evaluate whether a population-based clinical program offered to patients with recent-onset work disability caused by MSDs is cost-effective. Randomized, controlled intervention study. The inclusion and follow-up periods each lasted 12 months. Three health districts in Madrid, Spain. All patients with MSD-related temporary work disability in 1998 and 1999. The control group received standard primary care management, with referral to specialized care if needed. The intervention group received a specific program, administered by rheumatologists, in which care was delivered during regular visits and included 3 main elements: education, protocol-based clinical management, and administrative duties. Efficacy variables were 1) days of temporary work disability and 2) number of patients with permanent work disability. All analyses were done on an intention-to-treat basis. 1,077 patients were included in the study, 7805 in the control group and 5272 in the intervention group, generating 16,297 episodes of MSD-related temporary work disability. These episodes were shorter in the intervention group than in the control group (mean, 26 days compared with 41 days; P < 0.001), and the groups had similar numbers of episodes per patient. Fewer patients received long-term disability compensation in the intervention group (n = 38 [0.7%]) than in the control group (n = 99 [1.3%]) (P < 0.005). Direct and indirect costs were lower in the intervention group than in the control group. To save 1 day of temporary work disability, 6.00 dollars had to be invested in the program. Each dollar invested generated a benefit of 11.00 dollars. The program's net benefit was in excess of 5 million dollars. The study was unblinded. Implementation of the program, offered to the general population, improves short- and long-term work disability outcomes and is cost-effective.

Operational Use of Civil Space-Based Synthetic Aperture Radar (SAR)

NASA Technical Reports Server (NTRS)

Montgomery, Donald R. (Editor)

1996-01-01

Synthetic Aperture Radar (SAR) is a remote-sensing technology which uses the motion of the aircraft or spacecraft carrying the radar to synthesize an antenna aperture larger than the physical antenna to yield a high-spatial resolution imaging capability. SAR systems can thus obtain high-spatial resolution geophysical measurements of the Earth over wide surface areas, under all-weather, day/night conditions. This report was prepared to document the results of a six-month study by an Ad Hoc Interagency Working Group on the Operational Use of Civil (i.e., non-military) Space-based Synthetic Aperture Radar (SAR). The Assistant Administrator of NOAA for Satellite and Information Services convened this working group and chaired three meetings of the group over a six-month period. This action was taken in response to a request by the Associate Administrator of NASA for Mission to Planet Earth for an assessment of operational applications of SAR to be accomplished in parallel with a separate study requested of the Committee on Earth Studies of the Space Studies Board of the National Research Council on the scientific results of SAR research missions. The representatives of participating agencies are listed following the Preface. There was no formal charter for the working group or long term plans for future meetings. However, the working group may be reconstituted in the future as a coordination body for multiagency use of operational SAR systems.

A Conceptual Model for Analysing Collaborative Work and Products in Groupware Systems

NASA Astrophysics Data System (ADS)

Duque, Rafael; Bravo, Crescencio; Ortega, Manuel

Collaborative work using groupware systems is a dynamic process in which many tasks, in different application domains, are carried out. Currently, one of the biggest challenges in the field of CSCW (Computer-Supported Cooperative Work) research is to establish conceptual models which allow for the analysis of collaborative activities and their resulting products. In this article, we propose an ontology that conceptualizes the required elements which enable an analysis to infer a set of analysis indicators, thus evaluating both the individual and group work and the artefacts which are produced.

Phase portraits of the full symmetric Toda systems on rank-2 groups

We continue investigations begun in our previous works where we proved that the phase diagram of the Toda system on special linear groups can be identified with the Bruhat order on the symmetric group if all eigenvalues of the Lax matrix are distinct or with the Bruhat order on permutations of a multiset if there are multiple eigenvalues. We show that the phase portrait of the Toda system and the Hasse diagram of the Bruhat order coincide in the case of an arbitrary simple Lie group of rank 2. For this, we verify this property for the two remaining rank-2 groups, Sp(4,ℝ) and the real form of G2.

Spacecraft operations including ground system operations are generally realized by various large or small scale group work which is done by operators, engineers, managers, users and so on, and their positions are geographically distributed in many cases. In face-to-face work environments, it is easy for them to understand each other. However, in distributed work environments which need communication media, if only using audio, they become estranged from each other and lose interest in and continuity of work. It is an obstacle to smooth operation of spacecraft. NASDA has developed an experimental model of a new real-time operation control system called 'ADOLIS' (ADvanced On-Line System) adopted to such a distributed environment using a multi-media system dealing with character, figure, image, handwriting, video and audio information which is accommodated to operation systems of a wide range including spacecraft and ground systems. This paper describes the results of the development of the experimental model.

After bills to launch the Social Security and Tax Number System were enacted in 2013, health and political officials have considered the Healthcare Number System (the System). However, little is known about doctors' awareness and concerns about the System. This study aimed to measure how many doctors disagree with the System, examine the doctors' characteristics, and analyze the benefits and harms of the System that they identified. A cross-sectional survey was conducted of doctors via the Internet. The participants were selected from a convenience sample of a panel of doctors based on stratified sampling including four groups: working at a hospital and <45 years; working at a hospital and ≥45 years; working at a clinic and <45 years; and working at a clinic and ≥45 years. The main outcome was how many doctors agreed or disagreed with the System. The prevalence was calculated for each group, and their characteristics were examined using multivariable logistic regression analysis. The responses to open-ended questions concerning the Systems' benefits and harms were analyzed using qualitative content analysis. There were 562 respondents (68%). By group, 16/143 (11%), 25/138 (18%), 31/132 (23%), and 43/149 (29%) doctors, respectively, thought that the System was unnecessary. The variables that correlated with the main outcome were age (per 5 years; odds ratio [95% confidence interval], 1.14 [1.01-1.29]) and type of medical facility (working at a clinic; 1.99 [1.30-3.08]). The doctors identified that unifying information could decrease administrative duties, facilitate inter-facility collaboration, and prevent inappropriate medical consultations. This could result in decreased healthcare costs and personalized healthcare. However, the doctors also identified that integrating information and dealing with big data could increase information leakage and information management, cause over-monitoring of doctors, and enable the inappropriate use of integrated information. This could result in deteriorating healthcare. Since some information should not be integrated, the System raises ethical considerations about privacy. Among the doctors surveyed here, 10-30% thought the System was unnecessary. These respondents tended to be older and work at a clinic. The System could decrease the cost of healthcare and enable personalized healthcare but could also increase information leakage and information management, cause over-monitoring of doctors, and enable the inappropriate use of integrated information. Prior to System introduction, we should facilitate consensus-building about protecting and utilizing personal information as well as consider the related ethical issues, and doctors' characteristics and concerns.

The lack of sufficient numbers of professional nurses in the healthcare system in Taiwan is an issue that affects the sustainability of this system and that relates closely to working conditions. The present study explores the expectations that nurses hold with regard to working conditions and the operation of a flexible system in hospitals. A literature review and focus-group interviews were used to develop the questionnaire Working Conditions and Flexible System. A total of 1,150 copies of this questionnaire were distributed to practicing nurses using stratified random sampling, with 1,146 valid copies returned for a valid recovery rate of 99.65%. The results show that the expectations of participants concerning working conditions and a flexible system focus on the 6 factors of task, numerical, divisional, temporal, wages, and leading flexibility. The total mean was 4.35 (SD=0.42). The means for the 6 types of flexibility were all greater than 4.0. Participants deemed flexibility to be of high importance. The demographic variables hospital, work location, age, education level, work position, work unit, and total work years all affected the 6 types of flexibility significantly. The present study supports that the retention of nurses is significantly associated with working conditions and the operation of a flexible system. Administrators and mangers must create positive working conditions and a flexible system in order to enhance the retention and career development of nurses.

Murphy, G.; Garrett, H.; Samir, U.; Barnett, A.; Raitt, J.; Sullivan, J.; Katz, I.

1986-01-01

The Large Structures and Tethers Working Group sought to clarify the meaning of large structures and tethers as they related to space systems. Large was assumed to mean that the characteristic length of the structure was greater than one of such relevant plasma characteristics as ion gyroradius or debey length. Typically, anything greater than or equal to the Shuttle dimensions was considered large. It was agreed that most large space systems that the tether could be better categorized as extended length, area, or volume structures. The key environmental interactions were then identified in terms of these three categories. In the following Working Group summary, these categories and the related interactions are defined in detail. The emphasis is on how increases in each of the three spatial dimensions uniquely determine the interactions with the near-Earth space environment. Interactions with the environments around the other planets and the solar wind were assumed to be similar or capable of being extrapolated from the near-Earth results. It should be remembered in the following that the effects on large systems do not just affect specific technologies but will quite likely impact whole missions. Finally, the possible effects of large systems on the plasma environment, although only briefly discussed, were felt to be of potentially great concern.

Communication as a mechanism for cultural integration.

PubMed

Backstrom, Tomas; Hagstrom, Tom; Goransson, Susanna

2013-01-01

Providing autonomy for employees ensures innovation competence if balanced by integration into the organization. The aim of this article is to study processes leading to the integration of employees into the company culture. The two research questions are: What makes the culture of a work group similar to the company culture? How is a work group culture constructed? Theories that are employed concern culture as an organizing structure emerging in the interaction, company culture as a way to exert control, and social networks as a way to describe the interaction. Empirical data come from a merchant bank from which 105 respondents from ten work groups answered questions about their communication and their integration into the company culture. The results show that the sub-culture of the group emerges in communication between members of the group. There seems to be a self-reinforcing spiral between collegial talk, especially about goals, plans and changes at the work place, and cultural integration. All members of a group should be included in this communication to create a strong culture. The value system of the supervisor strongly influences the sub-culture of the work group. Appointing supervisors with values that correspond to the company culture and provide for employee communications is thus central for organizations using culture as a tool for control.

Largo, Thomas W; Rosenman, Kenneth D

2015-03-01

An amputation is one of the most serious injuries an employee can sustain and may result in lost time from work and permanent limitations that restrict future activity. A multidata source system has been shown to identify twice as many acute traumatic fatalities as one relying only on employer reporting. This study demonstrates the value of a multidata source approach for non-fatal occupational injuries. Data were abstracted from medical records of patients treated for work-related amputations at Michigan hospitals and emergency departments and were linked to workers' compensation claims data. Safety inspections were conducted by the Michigan Occupational Safety and Health Administration for selected cases. From 2006 through 2012, 4140 Michigan residents had a work-related amputation. In contrast, the Survey of Occupational Injury and Illness conducted by the Bureau of Labor Statistics (BLS) estimated that there were 1770 cases during this period. During the 7-year period, work-related amputation rates decreased by 26%. The work-related amputation rate for men was more than six times that for women. Industries with the highest work-related amputation rates were Wood Product Manufacturing and Paper Manufacturing. Power saws and presses were the leading causes of injury. One hundred and seventy-three safety inspections were conducted as a result of referrals from the system. These inspections identified 1566 violations and assessed $652 755 in penalties. The system was fairly simple to maintain, identified more than twice as many cases than either BLS or workers' compensation alone, and was useful for initiating inspection of high-risk worksites.

Based on our interviews, we found that the occupational trajectory of patients with SSc is influenced by the continuous interplay between four groups of factors. The first group concerns the values patients attribute to work, including identity, normality, financial value, social contact, and structure. The meaning of these values and how they relate to each other underlies the desire to work. A second group of factors is those influencing the balance between daily life, work participation, and medical condition (e.g. job content, flexibility in organising work, and the willingness to ask for accommodations at work). The occupational trajectory is also influenced by external factors, including availability of support, know-ledge of the disease, pressure to work, contact with medical professionals, and existing regulations and the patient's knowledge about them. Finally, the occupational trajectory is influenced by personal factors, including socio-demographics, psychological assets, and disease- and work-related personal factors. The decisions patients with SSc take concerning work depend on an interplay between many factors and, especially, on the patients' personal interpretation of these factors. These need to be taken into account when helping patients with SSc determine their occupational trajectory.

Laparoscopic approach profusely utilized in many surgical fields was enhanced by da Vinci robotic surgical system in range of surgery wards, imprimis in the United States today. There was multispecialized robotic centre program initiated in the Central Military Hospital in Prague in December 2005. Within the scope of implementing the da Vinci robotic system to clinical practice we executed robotic-assisted laparoscopic cholecystectomy. We have accomplished elective laparoscopic cholecystectomy using the da Vinci robotic surgical system. Operating working group (two doctors, two scrub nurses) had completed certificated foreign training. Both of the surgeons have many years experience of laparoscopic cholecystectomy. Operator controlled instruments from the surgeon's console, assistant placed clips on ends of cystic duct and cystic artery from auxiliary port after capnoperitoneum installation. We evacuated gallbladder in plastic bag from abdominal cavity in place of original paraumbilical port. We were exploiting three working arms in all our cases, holding surgical camera, electrocautery hook and Cadiere forceps. We had been observing procedure time, technical complications connected with robotic system, length of hospital stay and complication incidence rate. We managed to finish all operations in laparoscopic way. Group of our patients formed 11 male patients (35.5%) and 20 women (64.5%), mean aged 52.5 years in range of 27 77 years. The average operation procedure lasted 100 minutes, in the group of last 11 patients only 69 minutes. We recorded paraumbilical wound infections in 3 (9.7 %) patients. We had not experienced any technical problems with robotic surgical system. Length of hospital stay was 3 days. Considering our initial experience with robotic lasparoscopic cholecystectomy we evaluate da Vinci robotic surgical system to be safe and sophisticated operating manipulator which however does not substitute the surgeon key-role of controlling position and decision competences. Presented results of our group are comparable to conclusions of abroad published works.

HEP Software Foundation Community White Paper Working Group - Data Analysis and Interpretation

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

Bauerdick, Lothar

At the heart of experimental high energy physics (HEP) is the development of facilities and instrumentation that provide sensitivity to new phenomena. Our understanding of nature at its most fundamental level is advanced through the analysis and interpretation of data from sophisticated detectors in HEP experiments. The goal of data analysis systems is to realize the maximum possible scientific potential of the data within the constraints of computing and human resources in the least time. To achieve this goal, future analysis systems should empower physicists to access the data with a high level of interactivity, reproducibility and throughput capability. Asmore » part of the HEP Software Foundation Community White Paper process, a working group on Data Analysis and Interpretation was formed to assess the challenges and opportunities in HEP data analysis and develop a roadmap for activities in this area over the next decade. In this report, the key findings and recommendations of the Data Analysis and Interpretation Working Group are presented.« less

We review here the progress of the Variability of the American MOnsoon Systems (VAMOS) extremes working group since it was formed in February of 2010. The goals of the working group are to 1) develop an atlas of warm-season extremes over the Americas, 2) evaluate existing and planned simulations, and 3) suggest new model runs to address mechanisms and predictability of extremes. Substantial progress has been made in the development of an extremes atlas based on gridded observations and several reanalysis products including Modern Era Retrospective-Analysis for Research and Applications (MERRA) and Climate Forecast System Reanalysis (CFSR). The status of the atlas, remaining issues and plans for its expansion to include model data will be discussed. This includes the possibility of adding a companion atlas based on station observations based on the software developed under the World Climate Research Programme (WCRP) Expert Team on Climate Change. Detection and Indices (ETCCDI) activity. We will also review progress on relevant research and plans for the use and validation of the atlas results.

The articles in this special issue have demonstrated how unprecedented transitions have come with both challenges and opportunities for health financing. Against the background of these challenges and opportunities, the Working Group on Health Financing at the Chatham House Centre on Global Health Security laid out, in 2014, a set of policy responses encapsulated in 20 recommendations for how to make progress towards a coherent global framework for health financing. These recommendations pertain to domestic financing of national health systems, global public goods for health, external financing for national health systems and the cross-cutting issues of accountability and agreement on a new global framework. Since the Working Group concluded its work, multiple events have reinforced the group's recommendations. Among these are the agreement on the Addis Ababa Action Agenda, the adoption of the Sustainable Development Goals, the outbreak of Ebola in West Africa and the release of the Panama Papers. These events also represent new stepping stones towards a new global framework.

In the environmental sciences, researchers are increasingly relying on automated sensors as necessary components of their work. There are many software packages available that will help users download data from internet-connected data loggers; process, store, document, and analyze the data; or provide web-based geoportals for visualization and sharing of both spatial and time-series data. However, few (if any) software packages provide a complete, end-to-end system that will meet all of the needs of any given research group. Such systems often need to be designed and built as needed. Our group specializes in creating such systems. Our portals provide rapid data discovery and contextualization, and promote collaboration. We work at multiple scales, from a small lab working at a single site in the Chihuahuan desert (SEL-Jornada), to a community portal for environmental data from Barrow, Alaska (Barrow Area Information Database Information Management System [BAID-IMS]), to a project-tracking system for US Arctic research efforts (Arctic Research Mapping Application/Arctic Observing Viewer [ARMAP/AON]). Here, we share our experiences of creating scalable systems and improving practices that address both user community and research needs.

Work life and mental wellbeing of single and non-single working mothers in Scandinavia.

Bull, Torill; Mittelmark, Maurice B

This study examined levels and predictors of mental wellbeing in Scandinavian working single and non-single mothers, with a special focus on financial stress, job characteristics and work-family conflict. The European Social Survey Round 2 (2005) provided questionnaire data from 73 single and 432 non-single working mothers in Denmark, Sweden and Norway. Respondents answered questions about the outcome variables life satisfaction, happiness, and positive affect, and predictor variables financial stress, job characteristics, work-family conflict, and social support. Hierarchical multiple regression was used to assess the relationships between predictor variables and mental wellbeing outcomes. Single working mothers scored significantly lower on life satisfaction and happiness, but not on positive affect, than did non-single mothers. Financial stress was higher in the single mother group. There were no significant differences in levels of enriching or stressful job characteristics, or in levels of social support. While financial stress and work-family conflict were important predictors in both groups, the relationship between financial stress and wellbeing was far stronger in the single mother group. Confidant support was a significant predictor only in the single mother group, and social participation only in the non-single mothers group. This study suggests that the Scandinavian welfare democracies have not yet been successful in relieving the financial pressure experienced by single working mothers. Development of efficient financial support systems should be prioritized. Ways to reduce work-family conflict in both single and non-single mothers in Scandinavia should also be given increased attention.

Giannini, Susana Pimentel Pinto; Latorre, Maria do Rosário Dias de Oliveira; Ferreira, Léslie Piccolotto

2013-01-01

We aimed at verifying an association between voice disorders/stress and loss of work ability among female teachers who work in São Paulo's public school system. This is a paired case- control study. The case group was composed offiteachers with alterations in speech and larynges assessments, and the control group was formed by teachers without alterations in these evaluations who work in the same schools. Both groups answered the following questionnaires: Conditions of Vocal Production-Teachers, Job Stress Scale, and Work Ability Index. The analysis was performed using the chi-square association test and logistic regression models with the purpose of estimating the association between independent variables and voice disorders. We found differences between the groups in relation to stress in the workplace under high demand, a situation that poses greater risks of adverse reactions to the workers' physical and mental health. Regarding the ability to work, the categories poor and moderate ability for work are associated with voice disorders, regardless of job stress factors, age, and the unsatisfactory acoustic properties of the classrooms. This study confirmed the association between voice disorders and job stress, as well as between voice disorders and loss of work ability.

Learning disabled and average readers' working memory and comprehension: does metacognition play a role?

Swanson, H L; Trahan, M

1996-09-01

The present study investigates (a) whether learning disabled readers' working memory deficits that underlie poor reading comprehension are related to a general system, and (b) whether metacognition contributes to comprehension beyond what is predicted by working memory and word knowledge. To this end, performance between learning and disabled (N = 60) and average readers (N = 60) was compared on the reading comprehension, reading rate, and vocabulary subtests of the Nelson Skills Reading Test, Sentence Span test composed of high and low imagery words, and a Metacognitive Questionnaire. As expected, differences between groups in working memory, vocabulary, and reading measures emerged, whereas ability groups were statistically comparable on the Metacognitive Questionnaire. A within-group analysis indicated that the correlation patterns between working memory, vocabulary, metacognition, and reading comprehension were not the same between ability groups. For predicting reading comprehension, the metacognitive questionnaire best predicted learning disabled readers' performance, whereas the working memory span measure that included low-imagery words best predicted average achieving readers' comprehension. Overall, the results suggest that the relationship between learning disabled readers' generalised working memory deficits and poor reading comprehension may be mediated by metacognition.

Virtual strategies to improve transversal competences, using wikis in a collaborative work

Guinau, Marta; Playa, Elisabet

2016-04-01

A major educational aim in university degrees since the implementation of the European Credit Transfer System (ECTS) on the European universities is the work based on transversal competences. However, the first course students arrive at the Spanish universities with important deficiencies on some of these competences, especially regarding on oral and written expression, time management and collaborative work. The experience of the teachers involved in this work has revealed the coordination difficulty between the students to work in group, important deficiencies on information management and the stress caused by the oral presentations. The results presented here correspond to a teaching innovation project. It is based on: a) the development of works in groups of 3 or 4 students, proposed as flipped classrooms strategy and b) the implementation of a virtual tool (a wiki). This tool helps the students with scientific information management and facilitates the access of all the students belonging to the work group at the information provided by colleagues. The wiki also improves the monitoring and evaluation of the work and contributions of each student by teachers. Each group must develop a topic related to the subject - General Geology and Geochemistry - that the group chose from a list of earth sciences topics proposed by teachers. The resulting works are presented in poster and oral presentations (10 min. per group and 5 min. for questions). Each work is evaluated by teachers using the evidences provided on the wiki and by means of evaluation guides. Moreover, the students must self and co-evaluate the presented works. The implementation of this project has provided information to analyze the impact of these strategies and to quantify it in terms of 'Learning Analytics'.

We have conducted a comparative analysis of the work ability index (WAI) application in evaluation of the effectiveness of small peptides (cytogens) used as geroprotectors in the system of preventive medical nutrition of those working with occupational hazards. Our study revealed the necessity of an inclusion of small peptides into the system of preventive medical nutrition, health promotion in people working with occupational hazards and thus subjected to an accelerated aging. The combined application of peptide geroprotectors makes it possible to restore and enhance adaptive resources as well as to correct work ability and maintain health and well-being in different professional groups.

UAS Modeling of the Communication Links Study Results

NASA Technical Reports Server (NTRS)

Birr, Richard B.; Girgis, Nancy; Murray, Jennifer

2011-01-01

The Federal Aviation Administration (FAA) is the authority that grants access into, and operations within, the National Airspace System (NAS) for all aircraft, including Unmanned Aircraft Systems (UAS). The safe operation of UAS in the NAS must be assured if the full potential of UAS is to be realized and supported by the public and Congress. This report analyzed the communication systems that are needed for the safe operations of UAS in the NAS. Safe operations can be defined as the availability of the required links to carry the information to control the UAS and the return links to allow controllers to know where the UAS is at any given moment as well as how it is performing. This report is the end result of work performed jointly between the FAA and National Aeronautics and Space Administration (NASA)/Kennedy Space Center (NASA KSC). The work was done in support of the Radio Technical Commission for Aeronautics (RTCA) Special Committee 203 (SC-203) Control and Communications Working Group. The RTCA is a federal advisory committee to the FAA. Though the work was not under the direction of the working group, a large part of the specific values used in the simulations came from the working group. Specifically, all of the radio links were modeled based on the formulation completed by the working group. This report analyzed three scenarios from RTCA SC-203 that represent how a UAS would operate in the NAS. Each scenario was created using the Satellite Tool Kit (STK) modeling and simulation tool. The flight paths of the UAS were generated and the UAS dynamics were likewise modeled. Then each communication asset such as transmitters, receivers, and antennas were modeled and placed on the appropriate UAS, satellite, or Control Station (CS). After that, the radio links were analyzed for signal strength and antenna blockage, and the overall link performance was analyzed in detail. The goal was to obtain 99.9% availability on all of the radio communication links. In order to ensure the 99.9% availability, certain values for the telemetry transmitter will have to be increased slightly from I watt up to about 4 watts which is reasonable. The results of this analysis show that it is possible to send commands, during the airborne segment, to the Unmanned Aircraft (UA) and have the UA send back the system health and status with high availability of at least 99.9% of the time. This 99.9% availability included the condition of heavy rain at 90 mm/hr as well as interference from adjacent satellites. The link budget values used in this report were based on the work from the working group.

Estradiol concentrations and working memory performance in women of reproductive age.

PubMed

Hampson, Elizabeth; Morley, Erin E

2013-12-01

Estrogen has been proposed to exert a regulatory influence on the working memory system via actions in the female prefrontal cortex. Tests of this hypothesis have been limited almost exclusively to postmenopausal women and pharmacological interventions. We explored whether estradiol discernibly influences working memory within the natural range of variation in concentrations characteristic of the menstrual cycle. The performance of healthy women (n=39) not using hormonal contraceptives, and a control group of age- and education-matched men (n=31), was compared on a spatial working memory task. Cognitive testing was done blind to ovarian status. Women were retrospectively classified into low- or high-estradiol groups based on the results of radioimmunoassays of saliva collected immediately before and after the cognitive testing. Women with higher levels of circulating estradiol made significantly fewer errors on the working memory task than women tested under low estradiol. Pearson's correlations showed that the level of salivary estradiol but not progesterone was correlated inversely with the number of working memory errors produced. Women tested at high levels of circulating estradiol tended to be more accurate than men. Superior performance by the high estradiol group was seen on the working memory task but not on two control tasks, indicating selectivity of the effects. Consistent with previous studies of postmenopausal women, higher levels of circulating estradiol were associated with better working memory performance. These results add further support to the hypothesis that the working memory system is modulated by estradiol in women, and show that the effects can be observed under non-pharmacological conditions.

2014-04-01

This study was performed to evaluate occupational and fall injuries presenting to the ED, the risk factors associated with falls among all occupational injuries, and factors affecting prognosis. Data from ED-based Occupational Injury Surveillance System were analysed to investigate the occupational injuries. The 2147 occupational injury subjects were divided into two groups: fall (n = 213, 9.9%) and non-fall (n = 1934, 90.1%). Data including baseline and clinical characteristics were compared between the groups. The mean age was older in the fall group (46 vs 42 years old). The rate of construction site-related injury was 32% in the fall group and only 8% in the non-fall group. Injury occurrence during regular working hours (09.00 hours to 18.00 hours) was 70% in the fall group and 57% in the non-fall group. Injury severity using the Excess Mortality Ratio-adjusted Injury Severity Score (EMR-ISS) was more severe in the fall group than in the non-fall group, and days away from work were longer in the fall group than the non-fall group. Older age, compared with an age <29 years old and presence in a construction area during regular working hours were factors associated with fall injuries. Factors affecting prolonged absence for work were older age, higher EMR-ISS, fall injury and poor workplace environmental conditions. Risk factors associated with fall-related occupational injuries include older age and being at a construction area during regular working hours. Falls among occupational injuries are more severe than other injuries and result in longer work loss. © 2014 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

We explored the opportunities to develop a production system by leveraging our current prototype to (SOGP+PVFS) a new PVFS version.more » We delivered SOGP+PVFS codes to ANL PVFS2 group in 2008.We also talked about exploring a potential project on developing new parallel programming models and runtime systems for data-intensive scalable computing (DISC). The methodology is to evolve MPI towards DISC by incorporating some functions of Google MapReduce parallel programming model. More recently, we are together exploring how to leverage existing works to perform (1) coordination/aggregation of local I/O operations prior to movement over the WAN, (2) efficient bulk data movement over the WAN, (3) latency hiding techniques for latency-intensive operations. Since 2009, we start applying Hadoop/MapReduce to some HEC applications with LANL scientists John Bent and Salman Habib. Another on-going work is to improve checkpoint performance at I/O forwarding Layer for the Road Runner super computer with James Nuetz and Gary Gridder at LANL. Two senior undergraduates from our research group did summer internships about high-performance file and storage system projects in LANL since 2008 for consecutive three years. Both of them are now pursuing Ph.D. degree in our group and will be 4th year in the PhD program in Fall 2011 and go to LANL to advance two above-mentioned works during this winter break.

Keynote Address: ACR-NEMA standards and their implications for teleradiology

NASA Astrophysics Data System (ADS)

Horii, Steven C.

1990-06-01

The ACR-NEMA Standard was developed initially as an interface standard for the interconnection of two pieces of imaging equipment Essentially the Standard defmes a point-to-point hardware connection with the necessary protocol and data structure so that two differing devices which meet the specification will be able to communicate with each other. The Standard does not defme a particular PACS architecture nor does it specify a database structure. In part these are the reasons why implementers have had difficulty in using the Standard in a full PACS. Recent activity of the Working Groups formed by the Committee overseeing work on the ACR-NEMA Standard has changed some of the " flavor" of the Standard. It was realized that connection of PACS with hospital and radiology information systems (HIS and RIS) is necessary if a PACS is ever to be succesful. The idea of interconnecting heterogeneous computer systems has pushed Standards development beyond the scope of the original work. Teleradiology which inherenfly involves wide-area networking may be a direct beneficiary of the new directions taken by the Standards Working Groups. This paper will give a brief history of the ACR-NEMA effort describe the " parent" Standard and its " offspring" and describe the activity of the current Working Groups with particular emphasis on the potential impacts on teleradiology.

Developing nations bear a substantial portion of the global burden of injury. Public health surveillance models in developing countries should recognize injury risks for all levels of society and all causes and should incorporate various groups of workers and industries, including subsistence agriculture. However, many developing nations do not have an injury registration system; current data collection methods result in gross national undercounts of injuries, failing to distinguish injuries that occur during work. In 2006, we established an active surveillance system in Vietnam’s Xuan Tien commune and investigated potential methods for surveillance of work-related injuries. On the basis of our findings, we recommend a national model for work-related injury surveillance in Vietnam that builds on the existing health surveillance system. PMID:24028255

2012-06-01

The overall project RehaFutur, which has been initiated and funded by the Federal Ministry of Labour and Social Affairs and which involves all the actors of the vocational rehabilitation system, is aimed at advancing the development of the vocational rehabilitation system, so as to prepare it for the challenges ahead. The project started with a group of scientific experts, who formulated 8 fields of action for further developing the vocational rehab system. On this basis, 4 working groups were set up in the framework of a development project to elaborate concrete recommendations on how to implement the necessary changes in vocational rehabilitation. The topics dealt with by the working groups were "self-determination and self-responsibility", "regulation of the overall process", "occupation and working environment" as well as "research". The process was supervised by a steering group, the results were moreover discussed in workshops. Recommendations have been made for 10 subject areas: "consultation and information", "joint service points", "use of the internet", "quality assurance", "individualisation and greater flexibility", "orientation towards the working environment", "participation of the beneficiaries", "research", "legislation", "cooperation of the actors". The next step of the RehaFutur overall project is implementation of those recommendations. This needs to be done in an interdisciplinary manner and conjointly by the agencies and providers involved, including the beneficiaries as experts. As different framework conditions have to be taken into account, the process is a complex one and needs to be supported by systematic research. © Georg Thieme Verlag KG Stuttgart · New York.

One Health: Understanding and Improving Human, Animal, and Environmental Health as a Connected System Across NOAA

NASA Astrophysics Data System (ADS)

Giltz, S.; Trtanj, J.; Jones, H.

2017-12-01

The One Health concept recognizes that the health of humans is inextricably linked with the health of animals and the environment. With a growing world population, changing climate, and increased global travel One Health approaches are increasingly useful. The National Oceanic and Atmospheric Administration (NOAA) provides key stakeholders in the public health sector with the environmental intelligence they need to mitigate emerging health threats. The NOAA One Health Working Group's mission is to integrate and coordinate the network of observing systems and in situ sensors, detection and diagnostic capacity, research and modeling efforts, and sustained engagement with health partners to deliver useful information to public health and resource management communities. The NOAA One Health group divides its broad focus into themes: thermal extremes, water-borne disease, seafood security, Arctic, wildlife and zoonotic disease, vector-borne disease, and air quality (including wildfire). The group connects the work being done throughout NOAA to coordinate One Health related efforts, increase information sharing, promote interdisciplinary approaches, and work towards better disease prevention. We are working to enhance NOAA Science and services to deliver useful information on current and emerging health risks and benefits to health decision makers.

The purpose of this study was to investigate the consistency of working length control between hand instrumentation in comparison to engine driven Mtwo nickel-titanium rotary files. Forty extracted maxillary molars were selected and divided onto two parallel groups. The working lengths of the mesiobuccal root canals were estimated. The teeth were fixed in a phantom head. The root canal preparation was carried out group 1 (n=20) with hand K-files, (VDW, Munich, Germany) and group 2 (n=20) with Mtwo instruments (VDW, Munich, Germany). Vestibulo-oral and mesio-distal directional x-ray images were taken before the preparation with #10 K-file, inserted into the mesiobuccal root canal to the working length, and after preparation with #25, #30 and #40 files. Working lenght changes were detected with measurements between the radiological apex and the instrument tips. In the Mtwo group a difference in the working competency (p<0.05) could be noticed only in the vestibulo-oral direction from #10 to #40 file. The hand instrument group showed a significant difference in working length competency for each larger file size (p<0.05) (ANOVA). Regression analysis in the hand instrumentation group indicated a working length decrease with a mean of 0,2 mm after each consecutive file size (p<0.01). The outcome of our trial indicated a high consistency in working length control for root canal preparation under simulated clinical condition using Mtwo rotary files. Mtwo NiTi rotary file did therefore proved to be more accurate in comparison to the conventional hand instrumentation.

Bradt, David A; Aitken, Peter; FitzGerald, Gerry; Swift, Roger; O'Reilly, Gerard; Bartley, Bruce

2009-12-01

For more than a decade, emergency medicine (EM) organizations have produced guidelines, training, and leadership for disaster management. However, to date there have been limited guidelines for emergency physicians (EPs) needing to provide a rapid response to a surge in demand. The aim of this project was to identify strategies that may guide surge management in the emergency department (ED). A working group of individuals experienced in disaster medicine from the Australasian College for Emergency Medicine Disaster Medicine Subcommittee (the Australasian Surge Strategy Working Group) was established to undertake this work. The Working Group used a modified Delphi technique to examine response actions in surge situations and identified underlying assumptions from disaster epidemiology and clinical practice. The group then characterized surge strategies from their corpus of experience; examined them through available relevant published literature; and collated these within domains of space, staff, supplies, and system operations. These recommendations detail 22 potential actions available to an EP working in the context of surge, along with detailed guidance on surge recognition, triage, patient flow through the ED, and clinical goals and practices. The article also identifies areas that merit future research, including the measurement of surge capacity, constraints to strategy implementation, validation of surge strategies, and measurement of strategy impacts on throughput, cost, and quality of care.

NASA Supportability Engineering Implementation Utilizing DoD Practices and Processes

NASA Technical Reports Server (NTRS)

Smith, David A.; Smith, John V.

2010-01-01

The Ares I design and development program made the determination early in the System Design Review Phase to utilize DoD ILS and LSA approach for supportability engineering as an integral part of the system engineering process. This paper is to provide a review of the overall approach to design Ares-I with an emphasis on a more affordable, supportable, and sustainable launch vehicle. Discussions will include the requirements development, design influence, support concept alternatives, ILS and LSA planning, Logistics support analyses/trades performed, LSA tailoring for NASA Ares Program, support system infrastructure identification, ILS Design Review documentation, Working Group coordination, and overall ILS implementation. At the outset, the Ares I Project initiated the development of the Integrated Logistics Support Plan (ILSP) and a Logistics Support Analysis process to provide a path forward for the management of the Ares-I ILS program and supportability analysis activities. The ILSP provide the initial planning and coordination between the Ares-I Project Elements and Ground Operation Project. The LSA process provided a system engineering approach in the development of the Ares-I supportability requirements; influence the design for supportability and development of alternative support concepts that satisfies the program operability requirements. The LSA planning and analysis results are documented in the Logistics Support Analysis Report. This document was required during the Ares-I System Design Review (SDR) and Preliminary Design Review (PDR) review cycles. To help coordinate the LSA process across the Ares-I project and between programs, the LSA Report is updated and released quarterly. A System Requirement Analysis was performed to determine the supportability requirements and technical performance measurements (TPMs). Two working groups were established to provide support in the management and implement the Ares-I ILS program, the Integrated Logistics Support Working Group (ILSWG) and the Logistics Support Analysis Record Working Group (LSARWG). The Ares I ILSWG is established to assess the requirements and conduct, evaluate analyses and trade studies associated with acquisition logistic and supportability processes and to resolve Ares I integrated logistics and supportability issues. It established a strategic collaborative alliance for coordination of Logistics Support Analysis activates in support of the integrated Ares I vehicle design and development of logistics support infrastructure. A Joint Ares I - Orion LSAR Working Group was established to: 1) Guide the development of Ares-I and Orion LSAR data and serve as a model for future Constellation programs, 2) Develop rules and assumptions that will apply across the Constellation program with regards to the program's LSAR development, and 3) Maintain the Constellation LSAR Style Guide.

Robots that operate independently of one another will not be adequate to accomplish the future exploration tasks of long-distance autonomous navigation, habitat construction, resource discovery, and material handling. Such activities will require that systems widely share information, plan and divide complex tasks, share common resources, and physically cooperate to manipulate objects. Recognizing the need for interoperable robots to accomplish the new exploration initiative, NASA s Office of Exploration Systems Research & Technology recently funded the development of the Joint Technical Architecture for Robotic Systems (JTARS). JTARS charter is to identify the interface standards necessary to achieve interoperability among space robots. A JTARS working group (JTARS-WG) has been established comprising recognized leaders in the field of space robotics including representatives from seven NASA centers along with academia and private industry. The working group s early accomplishments include addressing key issues required for interoperability, defining which systems are within the project s scope, and framing the JTARS manuals around classes of robotic systems.

Emergence of grouping in multi-resource minority game dynamics

Huang, Zi-Gang; Zhang, Ji-Qiang; Dong, Jia-Qi; Huang, Liang; Lai, Ying-Cheng

2012-10-01

Complex systems arising in a modern society typically have many resources and strategies available for their dynamical evolutions. To explore quantitatively the behaviors of such systems, we propose a class of models to investigate Minority Game (MG) dynamics with multiple strategies. In particular, agents tend to choose the least used strategies based on available local information. A striking finding is the emergence of grouping states defined in terms of distinct strategies. We develop an analytic theory based on the mean-field framework to understand the ``bifurcations'' of the grouping states. The grouping phenomenon has also been identified in the Shanghai Stock-Market system, and we discuss its prevalence in other real-world systems. Our work demonstrates that complex systems obeying the MG rules can spontaneously self-organize themselves into certain divided states, and our model represents a basic and general mathematical framework to address this kind of phenomena in social, economical and political systems.

Microgravity combustion discipline working group summary of requirements for noncontact temperature measurements

NASA Technical Reports Server (NTRS)

Sacksteder, Kurt

1988-01-01

Current efforts of the Microgravity Combustion Working Group are summarized and the temperature measurement requirements for the combustion studies are defined. Many of the combustion systems that are studied in the low gravity environment are near-limit systems, that is, systems that are acting near the limit of flammability in terms of oxygen concentration or fuel concentration. Systems of this type are normally weak in the sense that there is a delicate balance between the heat released in the flame and the heat required to sustain the flame. Intrusive or perturbative temperature measurement probes can be inaccurate in these situations and in the limiting case extinguish the flame. Noncontact techniques then become the only way to obtain the required measurements. Noncontact measurement requirements for each of the three thermodynamic phases are described in terms of spatial and temporal resolution and temperature range.

Prevention of Child Sexual Abuse within the Family System: Guidelines for an Educational Social Group Work Program.

Masilo, Daniel Tuelo

2018-02-28

Children have the right to be brought up in safe environments. However, this right is often infringed by people who are supposed to provide love, care, and protection to children. These people can include biological fathers, step-fathers, brothers, cousins, aunts, mothers, and uncles. Violation of children takes place in a variety of ways, however, for the purpose of this paper, the focus is on child sexual abuse within the family system. A literature review is adopted as the methodology for the discussions in this paper. The purpose of this paper is firstly to demonstrate that child sexual abuse happens within the family system in South Africa, and secondly, to argue that the prevention of child sexual abuse should start within the family system and this can be achieved by conducting educational social group work sessions on child sexual abuse with the family members.

Assessing Group Interaction with Social Language Network Analysis

NASA Astrophysics Data System (ADS)

Scholand, Andrew J.; Tausczik, Yla R.; Pennebaker, James W.

In this paper we discuss a new methodology, social language network analysis (SLNA), that combines tools from social language processing and network analysis to assess socially situated working relationships within a group. Specifically, SLNA aims to identify and characterize the nature of working relationships by processing artifacts generated with computer-mediated communication systems, such as instant message texts or emails. Because social language processing is able to identify psychological, social, and emotional processes that individuals are not able to fully mask, social language network analysis can clarify and highlight complex interdependencies between group members, even when these relationships are latent or unrecognized.

Shiftwork is an essential part of our society. At the same time scientific evaluations demonstrate possible negative effects of shiftwork on the health status of the employees. Against this background we performed different studies to evaluate these effects within the specific shift system in a large chemical site in Germany. METHODS AND STUDY GROUP: To evaluate the impact of the different working times on job-related stress perception and work-life-balance we performed a cross-sectional study with 1494 blue collar workers (825 shift- and 669 day workers). Employees working in the rotating shift system reported lower frequencies of perceived time pressure (p = 0.008), and lower stress levels (p = 0.01), compared to the day workers. No significant difference was found with regard to work-life-balance and other aspects of job-related stress perception within both groups. Against the general opinion and study-results in the past we did not find a negative effect of our shift-system on self-reported stress. These results are in accordance with results of other cohort-studies on the specific shift system within the company demonstrating no difference in the health status of our shift workers compared to day workers. © Georg Thieme Verlag KG Stuttgart · New York.

Despite the presence of many textile and dyeing plants in Iran, we couldn't find similar studies in this country. Forthermore, considering progress in the dyeing process and engineering controls, assessment of respiratory system is important for these workers. The present study was performed to evaluate the respiratory system in dyeing workers. In a cross-sectional study, 101 dyeing workers (all dyeing workers in yazd) and 90 workers without respiratory exposures (control group), were evaluated. A questionnaire was filled for each participant included Venables questionnaire and some other questions about age, work experience, personal or familial history of asthma or atopy, acute and chronic respiratory symptoms; Then spirometry was performed before and after the shift work Results: The frequency of acute and chronic respiratory symptoms was significantly higher among dyeing workers than controls. According to the Venables questionnaire, 11.9% of the dyeing workers suffered from asthma. Means of FVC and FEV1 of pre-shift spirometry were lower than control (p< 0.001). Across-shift spirometry showed significant reduction of FVC (p< 0.001), FEV1 (p< 0.001), FEF25-75% (p= 0.05) and FEF25% (p= 0.007) in dyeing workers compared to the control group. Evaluation of dyeing workers' respiratory system in this study showed that despite development in dyeing processes and engineering controls, workers in this job show more prevalent acute and chronic symptoms, and across-shift changes in spirometric parameters were significantly higher in this work group than the control group. Therefore it is necessary to pay attention to the control of respiratory exposures in this job.

Development and implementation of an interprofessional consensus-driven process for review and optimization of smart-pump drug libraries and dosing limits are described. The Indianapolis Coalition for Patient Safety (ICPS), which represents 6 Indianapolis-area health systems, identified an opportunity to reduce clinically insignificant alerts that smart infusion pumps present to end users. Through a consensus-driven process, ICPS aimed to identify best practices to implement at individual hospitals in order to establish specific action items for smart-pump drug library optimization. A work group of pharmacists, nurses, and industrial engineers met to evaluate variability within and lack of scrutiny of smart-pump drug libraries. The work group used Lean Six Sigma methodologies to generate a list of key needs and barriers to be addressed in process standardization. The group reviewed targets for smart-pump drug library optimization, including dosing limits, types of alerts reviewed, policies, and safety best practices. The work group also analyzed existing processes at each site to develop a final consensus statement outlining a model process for reviewing alerts and managing smart-pump data. Analysis of the total number of alerts per device across ICPS-affiliated health systems over a 4-year period indicated a 50% decrease (from 7.2 to 3.6 alerts per device per month) after implementation of the model by ICPS member organizations. Through implementation of a standardized, consensus-driven process for smart-pump drug library optimization, ICPS member health systems reduced clinically insignificant smart-pump alerts.

The majority of public and private payers in the United States currently use the Medicare Resource-Based Relative Value Scale as the basis for physician payment. Many large group and academic practices have adopted this objective system of physician work to benchmark physician productivity, including using it, wholly or in part, to determine compensation. The Resource-Based Relative Value Scale survey instrument, used to value physician services, was designed primarily for procedural services, leading to current concerns that American Medical Association/Specialty Society Relative Value Scale Update Committee (RUC) surveys may undervalue nonprocedural evaluation and management services. The American Academy of Pediatrics is represented on the RUC, the committee charged with maintaining accurate physician work values across specialties and age groups. The Academy, working closely with other primary care and subspecialty societies, actively pursues a balanced RUC membership and a survey instrument that will ensure appropriate work relative value unit assignments, thereby allowing pediatricians to receive appropriate payment for their services relative to other services.

1986-01-01

The purpose of this report is to provide NASA with a rationale and recommendations for planning, implementing, and operating an Earth Observing System data and information system that can evolve to meet the Earth Observing System's needs in the 1990s. The Earth Observing System (Eos), defined by the Eos Science and Mission Requirements Working Group, consists of a suite of instruments in low Earth orbit acquiring measurements of the Earth's atmosphere, surface, and interior; an information system to support scientific research; and a vigorous program of scientific research, stressing study of global-scale processes that shape and influence the Earth as a system. The Eos data and information system is conceived as a complete research information system that would transcend the traditional mission data system, and include additional capabilties such as maintaining long-term, time-series data bases and providing access by Eos researchers to relevant non-Eos data. The Working Group recommends that the Eos data and information system be initiated now, with existing data, and that the system evolve into one that can meet the intensive research and data needs that will exist when Eos spacecraft are returning data in the 1990s.

Background: Employees can be counseled on how they feel about their job. If any particular dimension of their job is causing them dissatisfaction, they can be assisted to appropriately change it. In this study, we investigated the factors affecting job satisfaction from the perspective of employees working in the health system and thereby a quantitative measure of job satisfaction. Methods: Using eight focus group discussions (n=70), factors affecting job satisfaction of the employees were discussed. The factors identified from literature review were categorized in four groups: structural and managerial, social, work in it-self, environmental and welfare factors. Results: The findings confirmed the significance of structural and managerial, social, work in it-self, environmental and welfare factors in the level of job satisfaction. In addition, a new factor related to individual characteristics such as employee personal characteristics and development was identified. Conclusion: In order to improve the quality and productivity of work, besides, structural and managerial, social, work in it-self, environmental and welfare factors, policy makers should be taken into account individual characteristics of the employee as a factor affecting job satisfaction.

Work-related musculoskeletal system diseases are commonly observed among nurses, physiotherapists, dentists, and dieticians. To assess working postures of nurses, physiotherapists, dentists and dieticians, to identify whether low back pain (LBP) is present, and to put forth the correlation between LBP, working posture, and other factors. Twenty seven physiotherapists, 34 nurses, 30 dentists, and 16 dieticians were included. Impairment ratings of cases with LBP were analysed with Quebec Back Pain Disability Scale (Quebec). Working postures were analysed with Owako Working Posture Analysis System. LBP was observed in 70.09% of healthcare professionals. Of the individuals suffering from LBP, 57.2% were working with a risky posture. 40.63% of individuals without LBP were using risky working postures. Trunk and head posture distribution of individuals with and without LBP was found as different from each other (p < 0.05). LBP prevalence of dentists and nurses were higher compared to other groups (p < 0.05). Quebec scores of professionals with LBP were not different among occupations (p > 0.05). Quebec scores were observed as correlated with various factors in various occupation groups. Considering that head-neck and trunk postures are changeable factors that are among the factors affecting LBP, correcting the working posture gains importance.

The NASA SLR Operational Center is responsible for: 1) NASA SLR network control, sustaining engineering, and logistics; 2) ILRS mission operations; and 3) ILRS and NASA SLR data operations. NASA SLR network control and sustaining engineering tasks include technical support, daily system performance monitoring, system scheduling, operator training, station status reporting, system relocation, logistics and support of the ILRS Networks and Engineering Working Group. These activities ensure the NASA SLR systems are meeting ILRS and NASA mission support requirements. ILRS mission operations tasks include mission planning, mission analysis, mission coordination, development of mission support plans, and support of the ILRS Missions Working Group. These activities ensure than new mission and campaign requirements are coordinated with the ILRS. Global Normal Points (NP) data, NASA SLR FullRate (FR) data, and satellite predictions are managed as part of data operations. Part of this operation includes supporting the ILRS Data Formats and Procedures Working Group. Global NP data operations consist of receipt, format and data integrity verification, archiving and merging. This activity culminates in the daily electronic transmission of NP files to the CDDIS. Currently of all these functions are automated. However, to ensure the timely and accurate flow of data, regular monitoring and maintenance of the operational software systems, computer systems and computer networking are performed. Tracking statistics between the stations and the data centers are compared periodically to eliminate lost data. Future activities in this area include sub-daily (i.e., hourly) NP data management, more stringent data integrity tests, and automatic station notification of format and data integrity issues.

Previous work using Head-Up Displays (HUDs) suggests that the visual system parses the HUD and the outside world into distinct perceptual groups, with attention deployed sequentially to first one group and then the other. New experiments show that both groups can be processed in parallel in a divided attention search task, even though subjects have just processed a stimulus in one perceptual group or the other. Implications for models of visual attention will be discussed.

The purpose of this ex vivo study was to determine, in "open" and "closed" systems, whether the design has an influence on the penetration length of sodium hypochlorite mixed with a radiopaque contrast medium, measured in millimeters, when delivered using positive pressure (PP) and using sonic (SI) or passive ultrasonic (PUI) activation. Sixty single-rooted teeth were divided into two groups: open and closed systems (n=30). Root canal shaping was performed to a working length of 17 mm. The samples were divided into three sub-groups (n=10) according to irrigant delivery and activation: PP, and SI or PUI activation. By using radiographs, penetration length was measured, and vapor lock was assessed. For the closed group, the penetration distance means were: PP 15.715 (±0.898) mm, SI 16.299 (±0.738) mm and PUI 16.813 (±0.465) mm, with vapor lock occurring in 53.3% of the specimens. In the open group, penetration to 17 mm occurred in 97.6% of the samples, and no vapor lock occurred. Irrigant penetration and distribution evaluation using open and closed systems provide significantly different results. For closed systems, PUI is the most effective in delivering the irrigant to working length, followed by SI.

2013-01-01

In 2012 the International Association of Geodesy (IAG) and the International Astronomical Union (IAU) initiated a process to establish a Joint Working Group (JWG) on theory of Earth rotation with the purpose of promoting the development of improved theories of the Earth rotation which reach the accuracy required to meet the needs of the near future as recommended by, e.g. GGOS, the Global Geodetic Observing System of the IAG. The JWG was approved by both organizations in April 2013 with the chairs being the two authors of this paper. Its structure comprises three Sub Working Groups (SWGs) addressing Precession/Nutation, Polar Motion and UT1, the Numerical Solutions and Validation, respectively. The SWGs should work in parallel for the sake of efficiency, but should keep consistency as an overall goal. This paper offers a view of the objectives and scope of the JWG and reports about its initial activities and plans.

The National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health convened a working group in June 2011 to examine alternative institutional review board (IRB) models. The working group was held in response to proposed changes in the regulations for government-supported research and the proliferation of multicenter clinical trials where multiple individual reviews may be inefficient. Group members included experts in heart, lung, and blood research, research oversight, bioethics, health economics, regulations, and information technology (IT). The group discussed alternative IRB models, ethical concerns, metrics for evaluating IRBs, IT needs, and economic considerations. Participants noted research gaps in IRB best practices and in metrics. The group arrived at recommendations for process changes, such as defining specific IRB performance requirements in funding announcements, requiring funded researchers to use more efficient alternative IRB models, and developing IT systems to facilitate information sharing and collaboration among IRBs. Despite the success of the National Cancer Institute's central IRB (CIRB), the working group, concerned about the creation costs and unknown cost-efficiency of a new CIRB, and about the risk of shifting the burden of dealing with multiple IRBs from sponsors to research institutions, did not recommend the creation of an NHLBI-funded CIRB.

1992-02-01

A new applicable effective-field renormalization-group (ERFG) scheme for computing critical properties of Ising spins systems is proposed and used to study the phase diagrams of a quenched bond-mixed spin Ising model on square and Kagomé lattices. The present EFRG approach yields results which improves substantially on those obtained from standard mean-field renormalization-group (MFRG) method. In particular, it is shown that the EFRG scheme correctly distinguishes the geometry of the lattice structure even when working with the smallest possible clusters, namely N'=1 and N=2.

Selection criteria and facilitation training for the study of groupware

NASA Technical Reports Server (NTRS)

Robichaux, Barry P.

1993-01-01

Computer support for planning and decision making groups is a growing trend in the 90s. Groupware is a name often applied to group software and has been defined as 'computer-based systems that support groups engaged in a common task (or goal) and that provide an interface to a shared environment'. Unlike most single-user software, groupware assists user groups in their collaboration, coordination, and communication efforts. This paper focuses on groupware to support the meeting process. These systems are often called group decision support systems (GDSS), electronic meeting systems (EMS), or group support systems (GSS). The term 'meeting support groupware' is used here to include any computer-based system to support meetings. In order to understand this technology, one must first understand groups, what they do and the problems they face, and groupware, a wide range of technology to support group work. Guidelines for selecting groups for study as part of an overall research plan are provided in this document. These were taken from the literature and from persons for whom the information in this paper was targeted. Also, guidelines for facilitation training are discussed. Familiarity with known and accepted techniques are the principle duties of the facilitator and any form of training must include practice in using these techniques.

Over the past 5 years, the UAS integration into the NAS project has worked to reduce technical barriers to integration. A major focus of this work has been in support of RTCA SC-228. This committee has recently published the first UAS integration minimum performance standards (MOPS). This work has spanned detect and avoid (DAA) as well as command and control comm datalinks. I will discuss DAA efforts with focus on the human systems work. I will discuss how automation was discussed and addressed within this context. ICAO stood up a remotely piloted aircraft systems (RPAS) panel in 2014. They have developed an RPAS manual and are now working to revise existing annexes and standards and recommended practices. The Human In The System (HITS) has worked to infuse human factors guidelines into those documents. I will discuss that effort as well as how ICAO has defined and address autonomy. There is a great deal of interest in the control of multiple vehicles by a single operator. The UAS EXCOM Science and Research Panel (SARP) is holding a workshop on this topic in late June. I will discuss research performed on this topic when I worked for the Army and on-going work within the division and a NATO working group on Human-Autonomy Teaming.

It has been reported that many system engineers must work hard to produce computer systems, and some of them suffer from health impairment due to their hard work. The purpose of the present cross-sectional study was to investigate the situation of impaired health status of system engineers in projects with high job strain. Countermeasures against health impairment of the subjects in the projects with high job strain in practices of occupational health fields are discussed. The study subjects were five superiors and their 35 subordinates working on computer system projects with high job strain at a large computer systems corporation in the Tokyo area. The control group was comprised of three superiors and their 18 subordinates in the same corporation. From July to November, 2006, the above were interviewed by six occupational health nurses, who evaluated their health and recorded their health evaluation scores. The problems involved in producing the computer systems were sometimes very difficult to solve, even if they spent long hours working on them. The present study detected a tendency showing that healthy superiors' subordinates were unhealthy and unhealthy superiors' subordinates were healthy in the overload projects with high job strain, while this was not detected in the control groups. A few employees whose health deteriorated were faced with very hard jobs in the overload projects. This means that heavy workloads were unevenly distributed in the overload projects among superiors, and their subordinates, and the health of a few members with heavy workloads deteriorated due to the heavy workload. In order to improve such a situation, it may be important not only to commit the necessary number of employees whose working ability is high to the section but also to even the workload in the overload project by informing all members of the project the health impairment of a few members due to heavy workload, from the viewpoint of the practice of occupational health and risk management.

Background: Workers coming from lowland regions are at risk of developing acute mountain sickness (AMS) when working in low oxygen high-altitude areas. Objectives: The aim of this study was to improve the conditions that lead to hypoxia and ensure the safety of the high-altitude workers. We analyzed the influence of low atmospheric pressure on the oxygen enrichment process in high-altitude areas using an engineering method called low-pressure swing adsorption (LPSA). Methods: Fourteen male subjects were screened and divided into three groups by type of oxygen supply system used: (1) oxygen cylinder group; (2) LPSA oxygen dispersal group; and (3) control group. These tests included arterial oxygen saturation (SaO2), pulse rate (PR), breaths per minute (BPM), and blood pressure (BP). Results: The results showed that after supplying oxygen using the LPSA method at the tunnel face, the SaO2 of workers increased; the incidence of acute mountain sickness, PR, and BPM significantly decreased. Conclusions: The LPSA life support system was found to be a simple, convenient, efficient, reliable, and applicable approach to ensure proper working conditions at construction sites in high-altitude areas.

Simunić, Ana; Gregov, Ljiljana

2012-06-01

The objective of this study was to examine the perception of conflict between work and family roles and job, family, and life satisfaction among nurses in Croatia. One hundred and twenty-nine nurses (married mothers) working in hospitals in Zadar, Šibenik, and Split were divided in four groups according to their worktime schedule. The participants completed a survey, which included a set of sociodemographic-type questions, questions about the level and allocation of family responsibilities between spouses, and scales measuring the perceived negative effects of worktime, psychological demands of the work, work-family conflict, and semantic differential scales for measuring the affective and cognitive-evaluative component of job, family, and life satisfaction. This was the first study in Croatia to deal with work-family conflict among nurses or workers with different shift systems.The results of this study indicate that nurses working morning shifts only experienced less conflict between work and family than other groups of nurses, who worked the morning, afternoon, and the night shift. The cognitive-evaluative component of job satisfaction was the highest among morning shift nurses and the lowest in nurses who worked 12-hour shifts, while the affective component of life satisfaction was the lowest in nurses working irregular and backward rotated shifts. These results confirm that shiftwork makes the work-family role conflict even worse. They also support the view that the type of shift rotation matters.

Testing for pulmonary embolism often differs from that recommended by evidence-based guidelines. To assess the effectiveness of a handheld clinical decision-support system to improve the diagnostic work-up of suspected pulmonary embolism among patients in the emergency department. Cluster randomized trial. Assignment was by random-number table, providers were not blinded, and outcome assessment was automated. (ClinicalTrials.gov registration number: NCT00188032). 20 emergency departments in France. 1103 and 1768 consecutive outpatients with suspected pulmonary embolism. After a preintervention period involving 20 centers and 1103 patients, in which providers grew accustomed to inputting clinical data into handheld devices and investigators assessed baseline testing, emergency departments were randomly assigned to activation of a decision-support system on the devices (10 centers, 753 patients) or posters and pocket cards that showed validated diagnostic strategies (10 centers, 1015 patients). Appropriateness of diagnostic work-up, defined as any sequence of tests that yielded a posttest probability less than 5% or greater than 85% (primary outcome) or as strict adherence to guideline recommendations (secondary outcome); number of tests per patient (secondary outcome). The proportion of patients who received appropriate diagnostic work-ups was greater during the trial than in the preintervention period in both groups, but the increase was greater in the computer-based guidelines group (adjusted mean difference in increase, 19.3 percentage points favoring computer-based guidelines [95% CI, 2.9 to 35.6 percentage points]; P = 0.023). Among patients with appropriate work-ups, those in the computer-based guidelines group received slightly fewer tests than did patients in the paper guidelines group (mean tests per patient, 1.76 [SD, 0.98] vs. 2.25 [SD, 1.04]; P < 0.001). The study was not designed to show a difference in the clinical outcomes of patients during follow-up. A handheld decision-support system improved diagnostic decision making for patients with suspected pulmonary embolism in the emergency department.

Growing plants to provide food or psychological benefits to crewmembers is a common vision for the future of human spaceflight, often represented in media and in serious concept studies. The complexity of controlled environment agriculture, and plant growth in microgravity have and continue to be the subject of dedicated scientific research. However, actually implementing these systems in a way that will be cost effective, efficient, and sustainable for future space missions is a complex, multi-disciplinary problem. Key questions exist in many areas: human medical research in nutrition and psychology, horticulture, plant physiology and microbiology, multi-phase microgravity fluid physics, hardware design and technology development, and system design, operations and mission planning. This paper describes key knowledge gaps identified by a multi-disciplinary working group within the National Aeronautics and Space Administration (NASA).

Paperless Work Package (PWP) System is a computer program process that takes information from Asset Suite, provides a platform for other electronic inputs, Processes the inputs into an electronic package that can be downloaded onto an electronic work tablet or laptop computer, provides a platform for electronic inputs into the work tablet, and then transposes those inputs back into Asset Suite and to permanent SRS records. The PWP System will basically eliminate paper requirements from the maintenance work control system. The program electronically relays the instructions given by the planner to work on a piece of equipment which is currentlymore » relayed via a printed work package. The program does not control/approve what is done. The planner will continue to plan the work package, the package will continue to be routed, approved, and scheduled. The supervisor reviews and approves the work to be performed and assigns work to individuals or to a work group. (The supervisor conducts pre job briefings with the workers involved in the job) The Operations Manager (Work Controlling Entity) approves the work package electronically for the work that will be done in his facility prior to work starting. The PWP System will provide the package in an electronic form.

Clinical studies are needed to evaluate the entire digital and conventional workflows in prosthetic dentistry. The purpose of the second part of this clinical study was to compare the laboratory production time for tooth-supported single crowns made with 4 different digital workflows and 1 conventional workflow and to compare these crowns clinically. For each of 10 participants, a monolithic crown was fabricated in lithium disilicate-reinforced glass ceramic (IPS e.max CAD). The computer-aided design and computer-aided manufacturing (CAD-CAM) systems were Lava C.O.S. CAD software and centralized CAM (group L), Cares CAD software and centralized CAM (group iT), Cerec Connect CAD software and lab side CAM (group CiL), and Cerec Connect CAD software with centralized CAM (group CiD). The conventional fabrication (group K) included a wax pattern of the crown and heat pressing according to the lost-wax technique (IPS e.max Press). The time for the fabrication of the casts and the crowns was recorded. Subsequently, the crowns were clinically evaluated and the corresponding treatment times were recorded. The Paired Wilcoxon test with the Bonferroni correction was applied to detect differences among treatment groups (α=.05). The total mean (±standard deviation) active working time for the dental technician was 88 ±6 minutes in group L, 74 ±12 minutes in group iT, 74 ±5 minutes in group CiL, 92 ±8 minutes in group CiD, and 148 ±11 minutes in group K. The dental technician spent significantly more working time for the conventional workflow than for the digital workflows (P<.001). No statistically significant differences were found between group L and group CiD or between group iT and group CiL. No statistical differences in time for the clinical evaluation were found among groups, indicating similar outcomes (P>.05). Irrespective of the CAD-CAM system, the overall laboratory working time for a digital workflow was significantly shorter than for the conventional workflow, since the dental technician needed less active working time.

Investigating the occurrence, quantity, quality, distribution, and movement of the Nation 's water resources is the principal mission of the U.S. Geological Survey 's Water Resources Division. Reports of these investigations are published and available to the public. To accomplish this mission, the Division requires substantial computer technology to process, store, and analyze data from more than 57,000 hydrologic sites. The Division 's computer resources are organized through the Distributed Information System Program Office that manages the nationwide network of computers. The contract that provides the major computer components for the Water Resources Division 's Distributed information System expires in 1991. Five work groups were organized to collect the information needed to procure a new generation of computer systems for the U. S. Geological Survey, Water Resources Division. Each group was assigned a major Division activity and asked to describe its functional requirements of computer systems for the next decade. The work groups and major activities are: (1) hydrologic information; (2) hydrologic applications; (3) geographic information systems; (4) reports and electronic publishing; and (5) administrative. The work groups identified 42 functions and described their functional requirements for 1988, 1992, and 1997. A few new functions such as Decision Support Systems and Executive Information Systems, were identified, but most are the same as performed today. Although the number of functions will remain about the same, steady growth in the size, complexity, and frequency of many functions is predicted for the next decade. No compensating increase in the Division 's staff is anticipated during this period. To handle the increased workload and perform these functions, new approaches will be developed that use advanced computer technology. The advanced technology is required in a unified, tightly coupled system that will support all functions simultaneously. The new approaches and expanded use of computers will require substantial increases in the quantity and sophistication of the Division 's computer resources. The requirements presented in this report will be used to develop technical specifications that describe the computer resources needed during the 1990's. (USGS)

This report takes into account the IAU Working Group for Planetary System Nomenclature (WGPSN) and the IAU Committee on Small Body Nomenclature (CSBN) definition of dwarf planets, introduces improved values for the pole and rotation rate of Mercury, returns the rotation rate of Jupiter to a previous value, introduces improved values for the rotation of five satellites of Saturn, and adds the equatorial radius of the Sun for comparison. It also adds or updates size and shape information for the Earth, Mars’ satellites Deimos and Phobos, the four Galilean satellites of Jupiter, and 22 satellites of Saturn. Pole, rotation, and size information has been added for the asteroids (21) Lutetia, (511) Davida, and (2867) Šteins. Pole and rotation information has been added for (2) Pallas and (21) Lutetia. Pole and rotation and mean radius information has been added for (1) Ceres. Pole information has been updated for (4) Vesta. The high precision realization for the pole and rotation rate of the Moon is updated. Alternative orientation models for Mars, Jupiter, and Saturn are noted. The Working Group also reaffirms that once an observable feature at a defined longitude is chosen, a longitude definition origin should not change except under unusual circumstances. It is also noted that alternative coordinate systems may exist for various (e.g. dynamical) purposes, but specific cartographic coordinate system information continues to be recommended for each body. The Working Group elaborates on its purpose, and also announces its plans to occasionally provide limited updates to its recommendations via its website, in order to address community needs for some updates more often than every 3 years. Brief recommendations are also made to the general planetary community regarding the need for controlled products, and improved or consensus rotation models for Mars, Jupiter, and Saturn.

2012-04-01

Many in vitro studies have debated over the ability of different irrigant delivery and/or agitation systems to reach the apical third of curved root canals; however, little is known about irrigant penetration in vivo. Therefore, the purpose of this study was to compare the efficacy of the conventional endodontic irrigation needle, passive ultrasonic irrigation (PUI), and a negative pressure system for irrigant delivery to working length (WL) of mesial canals of mandibular molars. Thirty mesial canals of 30 vital mandibular first or second molars were randomly assigned into 3 groups (n = 10): (1) Monoject syringe with 27-gauge needle; (2) PUI with IrriSafe tip; and (3) EndoVac system. All canals were treated following the same preparation protocol to size 35/0.04 by using 5.25% NaOCl as irrigant during preparation procedure. Before obturation, canals were irrigated with 1 mL of a radiopaque solution by using the assigned irrigation system, and a digital radiograph was taken by using a parallel technique. With the aid of image editing software the distance between WL and maximum irrigant penetration was measured. Mean distances for Monoject, PUI, and EndoVac groups were 1.51 mm, 0.21 mm, and 0.42 mm, respectively. Analysis of variance test showed statistically significant differences between groups (P < .001). Tukey honestly significant difference test showed statistically significant differences between the Monoject group and the other 2 groups (P < .001) but no significant differences between PUI and EndoVac groups (P = .06). PUI and EndoVac are more effective than the conventional endodontic needle in delivering irrigant to WL of root canals. Copyright © 2012 American Association of Endodontists.

Changes in the working environment will also influence the work of physicians. The greatest of these changes on the Finnish scale, the SOTE reform (the reform in social welfare and public health services), still lies ahead. Labor shortage, on-call duties and patient record systems providing little support to work add to the burden. In surveys related to psychosocial working conditions, physicians' greatest work load factors have been rush, forced working pace and poor communication despite the fact that, on average, they consider their working conditions to be good, frequently better than those of other professional groups, and are committed to carry on with their work until retirement age. Although psychic symptoms and sleep disturbances are common among physicians, there are fewer disability pensions due to e.g. depression among physicians than in other professional groups. Among the municipal professions, physicians have nearly the lowest rate of job absenteeism due to sickness. Challenges brought about by the changes in physician's work can be met with fair management, development of the social capital of the work community, organization of tasks and flexibility of working hours.

Existing research has documented that shiftwork consequences may depend on the shift system parameters. Fast rotating systems (1-3 shifts of the same kind in a row) and day work have been found to be less disruptive biologically and socially than slower rotating systems and afternoon and night work. The aim of this study was to compare day workers and shift workers of different systems in terms of rotation speed and shifts worked with regard to work-family and family-work positive and negative spillover, marital communication style, job satisfaction and health. Employees (N = 168) of the maintenance workshops of transportation service working different shift systems (day shift, weekly rotating 2 and 3‑shift system, and fast rotating 3-shift system) participated in the study. They completed the Work- Family Spillover Questionnaire, Marital Communication Questionnaire, Minnesota Job Satisfaction Questionnaire and the Physical Health Questionnaire (a part of the Standard Shiftwork Index). The workers of quicker rotating 3-shift systems reported significantly higher scores of family-to-work facilitation (F(3, 165) = 4.175, p = 0.007) and a higher level of constructive style of marital communication (Engagement F(3, 165) = 2.761, p = 0.044) than the workers of slower rotating 2-shift systems. There were no differences between the groups of workers with regard to health and job satisfaction. A higher level of work-family facilitation and a more constructive style of marital communication were found among the workers of faster rotating 3-shift system when compared to the workers of a slower rotating 2-shift system (afternoon, night). This may indicate that the fast rotating shift system in contrary to the slower rotating one is more friendly for the work and family domains and for the relationship between them.

Educational and intervention strategies for improving a shift system: an experience in a disabled persons' facility.

PubMed

Sakai, K; Watanabe, A; Kogi, K

1993-01-01

The improvement of an irregular three-shift system with anti-clockwise rotation of workers of a disabled persons' facility covering 42 h a week was a subject for management-labour debate. Workers were complaining of physical fatigue, high prevalence of low back pain, sleep shortages associated with short inter-shift intervals, and irregular holidays. With the co-operation of trade union members, an educational and intervention programme was designed to analyse, plan, and implement improved shift rotation schemes. The programme consisted of (a) a group study on the existing system and effects on health and working life; (b) joint planning of potential schemes; (c) communication and feedback (d) testing and evaluation; and (e) agreement on an improved system. The group study was undertaken by means of time study, questionnaire and physiological methods, and the results were jointly discussed. This led to the planning of alternative shift schemes incorporating more regular, clockwise rotation. It was agreed to stage a trial period with a view to shorter working hours. This experience indicated the importance of a stepwise intervention strategy with frequent dialogues and a participatory process focusing on the broad range of working life and health issues.

The main purpose of urine cytology is to detect high-grade urothelial carcinoma. With this principle in mind, The Paris System (TPS) Working Group, composed of cytopathologists, surgical pathologists, and urologists, has proposed and published a standardized reporting system that includes specific diagnostic categories and cytomorphologic criteria for the reliable diagnosis of high-grade urothelial carcinoma. This paper outlines the essential elements of TPS and the process that led to the formation and rationale of the reporting system. TPS Working Group, organized at the 2013 International Congress of Cytology, conceived a standardized platform on which to base cytologic interpretation of urine samples. The widespread dissemination of this approach to cytologic examination and reporting of urologic samples and the scheme's universal acceptance by pathologists and urologists is critical for its success. For urologists, understanding the diagnostic criteria, their clinical implications, and limitations of TPS is essential if they are to utilize urine cytology and noninvasive ancillary tests in a thoughtful and practical manner. This is the first international/inclusive attempt at standardizing urinary cytology. The success of TPS will depend on the pathology and urology communities working collectively to improve this seminal paradigm shift, and optimize the impact on patient care.

Working with the IAG geometric services (VLBI, SLR, GNSS, and DORIS) the Bureau continues to advocate for the expansion and upgrade of the space geodesy networks for the maintenance and improvement of the reference frame and other application, and for the extension and integration with other techniques. New sites are being established following the GGOS concept of "core" and co-location sites; new technologies are being implemented to enhance performance in data yield as well as accuracy. In particular, several groups are undertaking initiatives and seeking partnerships to update existing sites and expand the networks in geographic areas void of coverage. The Bureau continues to meet with organizations to discuss possibilities of new and expanded participation and to promote the concept of partnerships. The Bureau provides the opportunity for representatives from the services to meet and share progress and plans, and to discuss issues of common interest. The Bureau monitors the status and projects the evolution of the network based on information from the current and expected future participants. Of particular interest at the moment is the integration of gravity and tide gauge networks. The Committees and Joint Working Groups play an essential role in the Bureau activity. The Standing Committee on Performance Simulations and Architectural Trade-off (PLATO) uses simulation and analysis techniques to project future network capability and to examine trade-off options. The Committee on Data and Information is working on a strategy for a GGOS metadata system on a near term plan for data products and a more comprehensive longer-term plan for an all-inclusive system. The Committee on Satellite Missions is working to enhance communication with the space missions, to advocate for missions that support GGOS goals and to enhance ground systems support. The IERS Working Group on Site Survey and Co-location (also participating in the Bureau) is working to enhance standardization in procedures, outreach and to encourage new survey groups to participate, and improve procedures to determine systems reference points. The 2017-2018 Implementation Plan for the GGOS Bureau of Networks and Observations has been posted on the GGOS website. We will outline progress over the past two years and discuss the status of the network and updated plan.

Therapist in distress: team-supervision of social workers and family therapists who work and live under political uncertainty.

PubMed

Shamai, M

1998-01-01

This article describes and analyzes a 2-year supervision process with social workers and family therapists who live and work under conditions of uncertainty on the West Bank. The systemic orientation used in this specific approach to supervision emphasizes the double role of the therapist: one as part of the therapeutic system, and the second as a member of the same community that is living in political uncertainty. The analysis revealed that a long-term supervision process, in which the supervisor encouraged a containing context, was meaningful to the group. As a result of this secure atmosphere, the group was ready to talk about painful issues like loss as the result of war and terrorist attacks, loss as a result of immigration, and loss of ideals. Furthermore, the members of the group were ready to confront the possibility of relocation and their role in such a situation. The techniques used in the process, such as narrative and metaphors, were implemented by the members in their daily professional interventions. The flexibility between working on regular professional issues and issues related to stress and uncertainty seemed useful to the supervision, as well as the political dialogue that was created between the supervisor and the group.

COMIS -- an international multizone air-flow and contaminant transport model

Feustel, H.E.

1998-08-01

A number of interzonal models have been developed to calculate air flows and pollutant transport mechanisms in both single and multizone buildings. A recent development in multizone air-flow modeling, the COMIS model, has a number of capabilities that go beyond previous models, much as COMIS can be used as either a stand-alone air-flow model with input and output features or as an infiltration module for thermal building simulation programs. COMIS was designed during a 12 month workshop at Lawrence Berkeley National Laboratory (LBNL) in 1988-89. In 1990, the Executive Committee of the International Energy Agency`s Energy Conservation in Buildings andmore » Community Systems program created a working group on multizone air-flow modeling, which continued work on COMIS. The group`s objectives were to study physical phenomena causing air flow and pollutant (e.g., moisture) transport in multizone buildings, develop numerical modules to be integrated in the previously designed multizone air flow modeling system, and evaluate the computer code. The working group supported by nine nations, officially finished in late 1997 with the release of IISiBat/COMIS 3.0, which contains the documented simulation program COMIS, the user interface IISiBat, and reports describing the evaluation exercise.« less

The high rate of violence in the healthcare sector supports the need for greater surveillance efforts. The purpose of this study was to use a province-wide workplace incident reporting system to calculate rates and identify risk factors for violence in the British Columbia healthcare industry by occupational groups, including nursing. Data were extracted for a 1-year period (2004-2005) from the Workplace Health Indicator Tracking and Evaluation database for all employee reports of violence incidents for four of the six British Columbia health authorities. Risk factors for violence were identified through comparisons of incident rates (number of incidents/100,000 worked hours) by work characteristics, including nursing occupations and work units, and by regression models adjusted for demographic factors. Across health authorities, three groups at particularly high risk for violence were identified: very small healthcare facilities [rate ratios (RR) = 6.58, 95% CI =3.49, 12.41], the care aide occupation (RR = 10.05, 95% CI = 6.72, 15.05), and paediatric departments in acute care hospitals (RR = 2.22, 95% CI = 1.05, 4.67). The three high-risk groups warrant targeted prevention or intervention efforts be implemented. The identification of high-risk groups supports the importance of a province-wide surveillance system for public health planning.

The purpose of this study was to determine the effectiveness of a novel, noninvasive perfusion enhancement system versus beds with integrated alternating pressure capabilities for the prevention of hospital-acquired sacral region (sacral, coccygeal, and ischium) pressure injuries in a high-risk, acute care patient population. A prospective randomized trial of high-risk inpatients without preexisting sacral region pressure injuries was conducted. The sample comprised 431 randomly enrolled adult patients in a 300-bed tertiary care community teaching hospital. Subjects were randomly allocated to one of 2 groups: control and experimental. Both groups received "standard-of-care" pressure injury prevention measures per hospital policy, and both were placed on alternating pressure beds during their hospital stays. In addition, patients in the experimental group used a noninvasive perfusion enhancement system placed on top of their alternating pressure beds and recovery chairs throughout their hospital stay. Fischer's exact probability test was used to compare group differences, and odds ratio (OR) were calculated for comparing pressure injury rates in the experimental and control groups. Three hundred ninety-nine patients completed the trial; 186 patients were allocated to the experimental group and 213 patients to the control group. Eleven patients in the control group versus 2 in the experimental group developed hospital-acquired sacral region pressure injuries (51.6% vs 1.07%; P = .024). Control patients were 5.04 times more likely to develop hospital-acquired sacral region pressure injuries (OR = 0.1996; 95% CI, 0.0437-0.9125). Patients using a noninvasive perfusion enhancement system developed significantly fewer hospital-acquired sacral pressure injuries than those using an alternating pressure bed without the perfusion enhancement system. These findings suggest that a perfusion enhancement system enhances the success of use of pressure redistributing beds for prevention of hospital-acquired sacral pressure injuries.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

1990-01-01

A study by NASA's User Information System Working Group for Space Station Freedom (SSF) has determined that the proposed onboard Data Management System, as initially configured, will be incapable of handling the data-generation rates typical of numerous scientific sensor payloads; many of these generate data at rates in excess of 10 Mbps, and there are at least four cases of rates in excess of 300 Mbps. The SSF Working Group has accordingly suggested an alternative conceptual architecture based on technology expected to achieve space-qualified status by 1995. The architecture encompasses recorders with rapid data-ingest capabilities and massive storage capabilities, optical delay lines allowing the recording of only the phenomena of interest, and data flow-compressing image processors.

2001-01-01

Modeling and simulating complex human-system interactions requires going beyond formal procedures and information flows to analyze how people interact with each other. Such work practices include conversations, modes of communication, informal assistance, impromptu meetings, workarounds, and so on. To make these social processes visible, we have developed a multiagent simulation tool, called Brahms, for modeling the activities of people belonging to multiple groups, situated in a physical environment (geographic regions, buildings, transport vehicles, etc.) consisting of tools, documents, and a computer system. We are finding many useful applications of Brahms for system requirements analysis, instruction, implementing software agents, and as a workbench for relating cognitive and social theories of human behavior. Many challenges remain for representing work practices, including modeling: memory over multiple days, scheduled activities combining physical objects, groups, and locations on a timeline (such as a Space Shuttle mission), habitat vehicles with trajectories (such as the Shuttle), agent movement in 3D space (e.g., inside the International Space Station), agent posture and line of sight, coupled movements (such as carrying objects), and learning (mimicry, forming habits, detecting repetition, etc.).

To make these social processes visible, we have developed a multiagent simulation tool, called Brahms, for modeling the activities of people belonging to multiple groups, situated in a physical environment (geographic regions, buildings, transport vehicles, etc.) consisting of tools, documents, and computer systems. We are finding many useful applications of Brahms for system requirements analysis, instruction, implementing software agents, and as a workbench for relating cognitive and social theories of human behavior. Many challenges remain for representing work practices, including modeling: memory over multiple days, scheduled activities combining physical objects, groups, and locations on a timeline (such as a Space Shuttle mission), habitat vehicles with trajectories (such as the Shuttle), agent movement in 3d space (e.g., inside the International Space Station), agent posture and line of sight, coupled movements (such as carrying objects), and learning (mimicry, forming habits, detecting repetition, etc.).

Health personnel are key players in developing and improving healthcare systems, caring for individuals and their communities, and helping improve quality of life. However, these professionals are often exposed to long working hours because of the pressing need for their services at potentially any time of day. The long working hours they endure are a major risk factor for both acute and chronic health problems. The present study aimed to analyze occurrences of long working hours and their association with individual characteristics and employment factors among workers in the municipal healthcare system in Belo Horizonte, Brazil. In this cross-sectional study, a ramdomly selected proportional sample of 1549 participants was analyzed from among the total of 13 602 workers in the Belo Horizonte municipal healthcare system in 2009. "Long" working hours were defined as >44 h/week. A self-administered questionnaire was used for accumulating data. Associations with outcomes were estimated using logistic regression, in univariate and multivariate models. The rate of occurrence of long working hours was 31.4% (95% CI 29.1-33.7). Lower educational level (high school, technical, or uncompleted undergraduate [OR 0.60, 95% CI 0.47-0.78 p < 0.001], or elementary [OR 0.33, 95% CI 0.19-0.55 p < 0.001]) was associated with a lower likelihood of self-reporting long working hours in relation to the group with the highest educational level (completed undergraduate or postgraduate). Male sex (OR 1.62, 95% CI 1.26-2.09 p < 0.001), having children (PR 1.54, 95% CI 1.20-1.97 p = 0.001), and being in the healthcare provider group (OR 1.82, 95% CI 1.40-2.35 p < 0.001) were factors associated with greater likelihood of long working hours. It was observed that number of long weekly working hours was related to individual characteristics and employment factors.

The effects of presentation pace and modality on learning a multimedia science lesson

NASA Astrophysics Data System (ADS)

Chung, Wen-Hung

Working memory is a system that consists of multiple components. The visuospatial sketchpad is the main entrance for visual and spatial information, whereas acoustic and verbal information is processed in the phonological loop. The central executive works as a coordinator of information from these two subsystems. Numerous studies have shown that working memory has a very limited capacity. Based on these characteristics of working memory, theories such as cognitive load theory and the cognitive theory of multimedia learning provide multimedia design principles. One of these principles is that when verbal information accompanying pictures is presented in audio mode instead of visually, learning can be more effective than if both text and pictures are presented visually. This is called the modality effect. However, some studies have found that the modality effect does not occur in some situations. In most experiments examining the modality effect, the multimedia is presented as system-paced. If learners are able to repeat listening as many times as they need, the superiority of spoken text over visual text seems lessened. One aim of this study was to examine the modality effect in a learner-controlled condition. This study also used the one-word-at-a-time technique to investigate whether the modality effect would still occur if both reading and listening rates were equal. There were 182 college students recruited for this study. Participants were randomly assigned to seven groups: a self-paced listening group, a self-paced reading group, a self text-block reading group, a general-paced listening group, a general-paced reading group, a fast-paced listening group, and a fast-paced reading group. The experimental material was a cardiovascular multimedia module. A three-by-two between-subjects design was used to test the main effect. Results showed that modality effect was still present but not between the self-paced listening group and the self text-block reading group. A post-study survey showed participants' different responses to the two modalities and their preferences as well. Results and research limitations are discussed and applications and future directions are also addressed.

[Health risk among workers employed in rubber footwear plant].

The aim of the study was to assess the health risk of workers performing specific jobs in the process of the rubber footwear production by defining the cause and length of temporary work disability, as well as mortality causes and level. The analysis was carried out in the groups of workers performing the following jobs: mixing, mill operation, pressing and vulcanizing (A); semi-product preparation and calendaring (B); finishing and sorting (C); production of polyvinyl chloride footwear (D); and auxiliary works (E). The sickness absence study covered all workers (208 men and 315 women) employed in a large rubber footwear company and performing all above-listed jobs in 1995. Standardized sick days ratio was used to analyze the risk of temporary work disability. Mortality rate was estimated on the basis of the results of the cohort study performed in the same company among workers who had worked at least three months during the years 1945-1985. The follow-up continued until 31 December 1997. The present study included sub-cohorts composed of 5628 men and 7197 women, performing jobs listed above. The results of both studies indicated the enhanced risk of cardiovascular diseases among workers employed in the basic phases of the production process. The increased risk of the diseases of the digestive system was observed in men and women employed in: finishing, sorting and packing of the products (group C); in men involved in mixing, pressing and vulcanizing (group A); and in women engaged in auxiliary works (group E). In addition, the enhanced risk of sickness absence due to the diseases of the respiratory, digestive, or genitourinary systems was related to the enhanced risk of death from malignant neoplasms in a given site. The analysis showed that the temporary work disability may be regarded as a parameter useful in early assessment of health effects of the work environmental hazards.

Whole-body magnetic resonance imaging (WB-MRI) is a relatively new technique that can enable assessment of the overall inflammatory status of people with arthritis, but standards for image acquisition, definitions of key pathologies, and a quantification system are required. Our aim was to perform a systematic literature review (SLR) and to develop consensus definitions of key pathologies, anatomical locations for assessment, a set of MRI sequences and imaging planes for the different body regions, and a preliminary scoring system for WB-MRI in inflammatory arthritis. An SLR was initially performed, searching for WB-MRI studies in arthritis, osteoarthritis, spondyloarthritis, or enthesitis. These results were presented to a meeting of the MRI in Arthritis Working Group together with an MR image review. Following this, preliminary standards for WB-MRI in inflammatory arthritides were developed with further iteration at the Working Group meetings at the Outcome Measures in Rheumatology (OMERACT) 2016. The SLR identified 10 relevant original articles (7 cross-sectional and 3 longitudinal, mostly focusing on synovitis and/or enthesitis in spondyloarthritis, 4 with reproducibility data). The Working Group decided on inflammation in peripheral joints and entheses as primary focus areas, and then developed consensus MRI definitions for these pathologies, selected anatomical locations for assessment, agreed on a core set of MRI sequences and imaging planes for the different regions, and proposed a preliminary scoring system. It was decided to test and further develop the system by iterative multireader exercises. These first steps in developing an OMERACT WB-MRI scoring system for use in inflammatory arthritides offer a framework for further testing and refinement.

Summary Since the passage of healthcare reform, there have been many discussions about how the mental health and substance use disorder (MH/SUD) system will need to change. Of the many components involved in a system redesign, the identification of essential ingredients is crucial to its success. In an effort to determine what essential ingredients the new MH/SUD system requires to optimally meet the needs of its customers, we convened a group of 16 multi-industrial experts who analyzed data collected from a string of 7 focus groups and 15 interviews with people dealing with or working in the SUD field. This paper summarizes the 11 essential ingredients our group identified. PMID:25243237

2000-01-01

Physiological parameters of vision were studied in three professional groups (a total of 1204 subjects): microscope operators, subjects working with magnifying glasses, and computer users. General and specific features of visual system fatigue formation were identified. Because of complete (in microscope operators) or partial (in subjects working with magnifying glasses and display users) "deprivation" of accommodation, these subjects develop early presbyopia (at the age of 30-35 years). In microscope operators long strain of accommodation system leads to professional myopia, while display users develop pseudomyopia. The highest overstrain is observed after 4 years of work in microscope operators, after 5 years in magnifying glass users, and after 6 years in computer users.

The CCSDS SOIS working groups are developing a range of standards for spacecraft onboard interfaces with the intention of promoting reuse of hardware and software designs across a range of missions while enabling interoperability of onboard systems from diverse sources. The CCSDS SOIS working groups released in June 2007 their red books for both Subnetwork and application support layers. In order to allow the verification of these recommended standards and to pave the way for future implementation onboard spacecrafts, it is essential for these standards to be prototyped on a representative spacecraft platform, to provide valuable feed back to the SOIS working group. A first reference implementation of both Subnetwork and Application Support SOIS services over SpaceWire and Mil-Std-1553 bus is thus being realised by SciSys Ltd and Astrium under an ESA contract.

This study is to evaluate the internal fit of the crown manufactured by CAD/CAM milling method and 3D printing method. The master model was fabricated with stainless steel by using CNC machine and the work model was created from the vinyl-polysiloxane impression. After scanning the working model, the design software is used to design the crown. The saved STL file is used on the CAD/CAM milling method and two types of 3D printing method to produce 10 interim crowns per group. Internal discrepancy measurement uses the silicon replica method and the measured data are analyzed with One-way ANOVA to verify the statistic significance. The discrepancy means (standard deviation) of the 3 groups are 171.6 (97.4) µm for the crown manufactured by the milling system and 149.1 (65.9) and 91.1 (36.4) µm, respectively, for the crowns manufactured with the two types of 3D printing system. There was a statistically significant difference and the 3D printing system group showed more outstanding value than the milling system group. The marginal and internal fit of the interim restoration has more outstanding 3D printing method than the CAD/CAM milling method. Therefore, the 3D printing method is considered as applicable for not only the interim restoration production, but also in the dental prosthesis production with a higher level of completion.

The Payload Advisory Panel of the Investigators Working Group (IWG) for the Earth Observing System (EOS) met 4 to 6 October 1993 in Herndon, Virginia. The Panel, originally composed of the Interdisciplinary Science Principal Investigators, was expanded to include all Principal Investigators and as such is now the IWG itself. The meeting also addressed directly a report from the EOS Data and Information System (EOSDIS) Advisory Panel. The meeting focused on payload issues in the years 2000 to 2005; however, some subjects in the nearer-term, most significantly EOSDIS, were considered. The overarching theme of convergence in Earth observations set a backdrop for the entire meeting. Other themes included: atmospheric chemistry; remote sensing of the global cycles of energy, water, and carbon in EOS; ocean and land-ice altimetry; and the EOSDIS. The Totol Solar Irradiance Monitoring Report and results from the Accelerated Canopy Chemistry Program are included as appendices.

Systems special investigation group overview

Mason, James B.; Dursch, Harry; Edelman, Joel

1992-01-01

The Systems Special Investigation Group (SIG) has undertaken investigations in the four major engineering disciplines represented by LDEF hardware: electrical, mechanical, thermal, and optical systems. Testing was planned for the highest possible level of assembly, and top level system tests for nearly all systems were performed at this time. Testing to date was performed on a mix of LDEF and individual experimenter systems. No electrical or mechanical system level failures attributed to the spaceflight environment were detected by the Systems SIG. Some low cost electrical components were used successfully, although relays were a continuing problem. Extensive mechanical galling was observed, but no evidence of coldwelding was identified. A working index of observed systems anomalies was created and will be used to support the tracking and resolution of these effects. LDEF hardware currently available to the Systems SIG includes most of the LDEF facility systems hardware, and some significant experimenter hardware as well. A series of work packages was developed for each of several subsystem types where further testing is of critical interest. The Systems SIG is distributing a regular newsletter to the greater LDEF community in order to maintain coherence in an investigation which is widely scattered both in subject matter and in geography. Circulation of this informal document has quadrupled in its first year.

The Auditory-Visual Speech Benefit on Working Memory in Older Adults with Hearing Impairment

Frtusova, Jana B.; Phillips, Natalie A.

2016-01-01

This study examined the effect of auditory-visual (AV) speech stimuli on working memory in older adults with poorer-hearing (PH) in comparison to age- and education-matched older adults with better hearing (BH). Participants completed a working memory n-back task (0- to 2-back) in which sequences of digits were presented in visual-only (i.e., speech-reading), auditory-only (A-only), and AV conditions. Auditory event-related potentials (ERP) were collected to assess the relationship between perceptual and working memory processing. The behavioral results showed that both groups were faster in the AV condition in comparison to the unisensory conditions. The ERP data showed perceptual facilitation in the AV condition, in the form of reduced amplitudes and latencies of the auditory N1 and/or P1 components, in the PH group. Furthermore, a working memory ERP component, the P3, peaked earlier for both groups in the AV condition compared to the A-only condition. In general, the PH group showed a more robust AV benefit; however, the BH group showed a dose-response relationship between perceptual facilitation and working memory improvement, especially for facilitation of processing speed. Two measures, reaction time and P3 amplitude, suggested that the presence of visual speech cues may have helped the PH group to counteract the demanding auditory processing, to the level that no group differences were evident during the AV modality despite lower performance during the A-only condition. Overall, this study provides support for the theory of an integrated perceptual-cognitive system. The practical significance of these findings is also discussed. PMID:27148106

Aims: To evaluate the association between working conditions and visual fatigue and mental health among systems analysts living in São Paulo, Brazil. Methods: A cross sectional study was carried out by a multidisciplinary team. It included: ergonomic analysis of work, individual and group interviews, and 553 self applied questionnaires in two enterprises. The comparison population numbered 136 workers in different occupations. Results: The study population mainly comprised young males. Among systems analysts, visual fatigue was associated with mental workload, inadequate equipment and workstation, low level of worker participation, being a woman, and subject's attitude of fascination by the computer. Nervousness and intellectual performance were associated with mental workload, inadequate equipment, work environment, and tools. Continuing education and leisure were protective factors. Work interfering in family life was associated with mental workload, difficulties with clients, strict deadlines, subject's attitude of fascination by the computer, and finding solutions of work problems outside work. Family support, satisfaction in life and work, and adequate work environment and tools were protective factors. Work interfering in personal life was associated with subject's attitude of fascination by the computer, strict deadlines, inadequate equipment, and high level of work participation. Satisfaction in life and work and continuing education were protective factors. The comparison population did not share common working factors with the systems analysts in the regression analysis. Conclusions: The main health effects of systems analysts' work were expressed by machine anthropomorphism, being very demanding, mental acceleration, mental absorption, and difficulty in dealing with emotions.

Bragg-Sitton, Shannon Michelle

The Organization for Economic Cooperation and Development /Nuclear Energy Agency (OECD/NEA) Nuclear Science Committee approved the formation of an Expert Group on Accident Tolerant Fuel (ATF) for LWRs (EGATFL) in 2014. Chaired by Kemal Pasamehmetoglu, INL Associate Laboratory Director for Nuclear Science and Technology, the mandate for the EGATFL defines work under three task forces: (1) Systems Assessment, (2) Cladding and Core Materials, and (3) Fuel Concepts. Scope for the Systems Assessment task force includes definition of evaluation metrics for ATF, technology readiness level definition, definition of illustrative scenarios for ATF evaluation, parametric studies, and selection of system codes. Themore » Cladding and Core Materials and Fuel Concepts task forces will identify gaps and needs for modeling and experimental demonstration; define key properties of interest; identify the data necessary to perform concept evaluation under normal conditions and illustrative scenarios; identify available infrastructure (internationally) to support experimental needs; and make recommendations on priorities. Where possible, considering proprietary and other export restrictions (e.g., International Traffic in Arms Regulations), the Expert Group will facilitate the sharing of data and lessons learned across the international group membership. The Systems Assessment Task Force is chaired by Shannon Bragg-Sitton (INL), while the Cladding Task Force will be chaired by a representative from France (Marie Moatti, Electricite de France [EdF]) and the Fuels Task Force will be chaired by a representative from Japan (Masaki Kurata, Japan Atomic Energy Agency [JAEA]).

Health care is a complex industry, consequently requiring a diverse group of health care executives leading initiatives for efficiency and effectiveness in patient care delivery. Value-based purchasing and pay for performance are at the top of the list for indicators of success, and many hospitals are merging into health care systems. The role of the system chief nurse executive is an evolving role to lead health care systems in clinical, operational, patient safety, and patient satisfaction processes and outcomes. The American Organization of Nurse Executives, being the voice for nursing leadership, convened a group of system chief nurse executives to address the role, function, and competencies needed for this significant and emerging role in health care. This article describes the role statement and system chief nurse executive competencies needed for success in the role. In addition, the next steps for addressing the needs of this group will be outlined in this article.

Brainstorming about next-generation computer-based documentation: an AMIA clinical working group survey.

Johnson, Kevin B; Ravich, William J; Cowan, John A

Computer-based software to record histories, physical exams, and progress or procedure notes, known as computer-based documentation (CBD) software, has been touted as an important addition to the electronic health record. The functionality of CBD systems has remained static over the past 30 years, which may have contributed to the limited adoption of these tools. Early users of this technology, who have tried multiple products, may have insight into important features to be considered in next-generation CBD systems. We conducted a cross-sectional, observational study of the clinical working group membership of the American Medical Informatics Association (AMIA) to generate a set of features that might improve adoption of next-generation systems. The study was conducted online over a 4-month period; 57% of the working group members completed the survey. As anticipated, CBD tool use was higher (53%) in this population than in the US physician offices. The most common methods of data entry employed keyboard and mouse, with agreement that these modalities worked well. Many respondents had experience with pre-printed data collection forms before interacting with a CBD system. Respondents noted that CBD improved their ability to document large amounts of information, allowed timely sharing of information, enhanced patient care, and enhanced medical information with other clinicians (all P < 0.001). Respondents also noted some important but absent features in CBD, including the ability to add images, get help, and generate billing information. The latest generation of CBD systems is being used successfully by early adopters, who find that these tools confer many advantages over the approaches to documentation that they replaced. These users provide insights that may improve successive generations of CBD tools. Additional surveys of CBD non-users and failed adopters will be necessary to provide other useful insights that can address barriers to the adoption of CBD by less computer literate physicians.

Electromyography Biofeedback Exergames to Enhance Grip Strength and Motivation.

2018-02-01

Hand strength weakness affects the performance of most activities of daily living. This study aims to design, develop, and test an electromyography (EMG) biofeedback training system based on serious games to promote motivation and synchronization and proper work intensity in grip exercises for improving hand strength. An EMG surface sensor, soft balls with different stiffness and three exergames, conforms the system to drive videogame clues in response to EMG-inferred grip strength, while overseeing motivation. An experiment was designed to study the effect of performing handgrip (HG) exercises with the proposed system versus traditional exercises. Participants, organized into two groups, followed a training program for each hand. One group followed a HG exergame training (ET) with the dominant hand and traditional HG training with the nondominant hand and inverse sequence by the second group. Initial and final grip forces were measured using a digital dynamometer. Questionnaires evaluated motivation and user experience, and exercise performance was evaluated in terms of work and rest time percentage and maximal voluntary contraction percentage over contraction periods. Data were analyzed for statistically significant differences and increase of means. Participants showed significantly better exercise performance and higher grip forces, with sustained intrinsic motivation and user experience, with the ET. Improvement in force level arises evidently from the synchronized work-rest time pattern and appropriated intensity of the muscle activity. This leads to support that EMG biofeedback exergames improve motor neurons firing and resting.

Several groups are implementing low‐cost host‐operated systems of strong‐motion accelerographs to support the somewhat divergent needs of seismologists and earthquake engineers. The Advanced National Seismic System Technical Implementation Committee (ANSS TIC, 2002), managed by the U.S. Geological Survey (USGS) in cooperation with other network operators, is exploring the efficacy of such systems if used in ANSS networks. To this end, ANSS convened a working group to explore available Class C strong‐motion accelerometers (defined later), and to consider operational and quality control issues, and the means of annotating, storing, and using such data in ANSS networks. The working group members are largely coincident with our author list, and this report informs instrument‐performance matters in the working group’s report to ANSS. Present examples of operational networks of such devices are the Community Seismic Network (CSN; csn.caltech.edu), operated by the California Institute of Technology, and Quake‐Catcher Network (QCN; Cochran et al., 2009; qcn.stanford.edu; November 2013), jointly operated by Stanford University and the USGS. Several similar efforts are in development at other institutions. The overarching goals of such efforts are to add spatial density to existing Class‐A and Class‐B (see next paragraph) networks at low cost, and to include many additional people so they become invested in the issues of earthquakes, their measurement, and the damage they cause.

The present study considers the production of knowledge and the interactions in the environment of research and their relationships in the system of caring in nursing and health. To elaborate a theoretical model of the organization of the practices used for caring, based on the experiences made by the research groups of administration and management in nursing, in Brazil. The study is based on grounded theory. Twelve leaders of research groups, working as professors in public universities in the south and the south-east of Brazil, distributed in sample groups, were interviewed. The core phenomenon 'research groups of administration and management in nursing: arrangements and interactions in the system of caring in nursing' was derived from the categories: conceptual bases and contexts of the research groups; experiencing interactions in the research groups; functionality of the research groups; and outputs of the research groups. The research groups are integrated in the system of caring in nursing. The activities of the Brazilian administration and management in nursing research groups are process oriented and in a process of constant renovation, socially relevant, operate in a complex scenario and contribute to the advancement of the organizations of the system of caring in nursing through strengthening the connection among academia, service and community. © 2011 The Authors.

Systems special investigation group overview

1991-01-01

The Systems Special Investigation Group (SIG) has undertaken investigations in the four major engineering disciplines represented in the Long Duration Exposure Facility (LDEF) hardware: electrical, mechanical, thermal, and optical systems. Testing was planned for the highest possible level of assembly, and top level system tests for nearly all systems were performed at this time. To date, testing was performed on a mix of LDEF and individual experimenter systems. No electrical or mechanical system level failures attributed to the spaceflight environment have yet been detected. Some low cost electrical components were used successfully, although relays were a continuing problem. Mechanical galling was observed unexpectedly, but no evidence of cold welding was identified yet. A working index of observed systems anomalies was created and will be used to support the tracking and resolution of these effects. The LDEF hardware currently available to the Systems SIG includes most of the LDEF systems hardware, and some significant experimenter hardware as well. A series of work packages was developed for each of several subsystem types where further testing is of critical interest. The System SIG is distributing a regular newsletter to the greater LDEF community in order to maintain coherence in an investigation which is widely scattered both in subject matter and in geography. Circulation of this informal document has quadrupled in its first year.

The role of trauma-related distractors on neural systems for working memory and emotion processing in posttraumatic stress disorder

The relevance of emotional stimuli to threat and survival confers a privileged role in their processing. In PTSD, the ability of trauma-related information to divert attention is especially pronounced. Information unrelated to the trauma may also be highly distracting when it shares perceptual features with trauma material. Our goal was to study how trauma-related environmental cues modulate working memory networks in PTSD. We examined neural activity in participants performing a visual working memory task while distracted by task-irrelevant trauma and non-trauma material. Recent post-9/11 veterans were divided into a PTSD group (n = 22) and a trauma-exposed control group (n = 20) based on the Davidson trauma scale. Using fMRI, we measured hemodynamic change in response to emotional (trauma-related) and neutral distraction presented during the active maintenance period of a delayed-response working memory task. The goal was to examine differences in functional networks associated with working memory (dorsolateral prefrontal cortex and lateral parietal cortex) and emotion processing (amygdala, ventrolateral prefrontal cortex, and fusiform gyrus). The PTSD group showed markedly different neural activity compared to the trauma-exposed control group in response to task-irrelevant visual distractors. Enhanced activity in ventral emotion processing regions was associated with trauma distractors in the PTSD group, whereas activity in brain regions associated with working memory and attention regions was disrupted by distractor stimuli independent of trauma content. Neural evidence for the impact of distraction on working memory is consistent with PTSD symptoms of hypervigilance and general distractibility during goal-directed cognitive processing.

International space agencies around the world are currently developing optical communication systems for Near Earth and Deep Space applications for both robotic and human rated spacecraft. These applications include both links between spacecraft and links between spacecraft and ground. The Interagency Operation Advisory Group (IOAG) has stated that there is a strong business case for international cross support of spacecraft optical links. It further concluded that in order to enable cross support the links must be standardized. This paper will overview the history and structure of the space communications international standards body, the Consultative Committee for Space Data Systems (CCSDS), that will develop the standards and provide an update on the proceedings of the Optical Communications Working Group within CCSDS. This paper will also describe the set of optical communications standards being developed and outline some of the issues that must be addressed in the next few years. The paper will address in particular the ongoing work on application scenarios for deep space to ground called High Photon Efficiency, for LEO to ground called Low Complexity, for inter-satellite and near Earth to ground called High Data Rate, as well as associated atmospheric measurement techniques and link operations concepts.

2015-04-01

The interdisciplinary postgraduate research and education programme - the Vienna Doctoral Programme on Water Resource Systems - was initiated in 2009. To date, 35 research students, three post-docs and ten faculty members have been engaged in the Programme, from ten research fields (aquatic microbiology, hydrology, hydro-climatology, hydro-geology, mathematical economics, photogrammetry, remote sensing, resource management, structural mechanics, and water quality). The Programme aims to develop research students with the capacity to work across the disciplines, to conduct cutting edge research and foster an international perspective. To do this, a variety of mechanisms are adopted that include research cluster groups, joint study sites, joint supervision, a basic study programme and a research semester abroad. The Programme offers a unique case study to explore if and how these mechanisms lead to research and education outcomes. Outcomes are grouped according to whether they are tangible (publications with co-authors from more than one research field, analysis of graduate profiles and career destinations) or non-tangible (interaction between researchers, networks and trust). A mixed methods approach that includes bibliometric analysis combined with interviews with students is applied. Bibliometric analysis shows that as the Programme has evolved the amount of multi-disciplinary work has increased (32% of the 203 full papers produced by the programme's researchers have authors from more than one research field). Network analysis to explore which research fields collaborate most frequently show that hydrology plays a significant role and has collaborated with seven of the ten research fields. Hydrology researchers seem to interact the most strongly with other research fields as they contribute understanding on water system processes. Network analysis to explore which individuals collaborate shows that much joint work takes place through the five research cluster groups (water resource management, land-surface processes, Hydrological Open Air Laboratory, water and health, modelling and risk). Student interviews highlight that trust between colleagues and supervisors, and the role of spaces for interaction (joint study sites, cluster group meetings, shared offices etc.) are important for joint work. Graduate analysis shows that students develop skills and confidence to work across disciplines through collaborating on their doctoral research. Working collaboratively during the doctorate appears to be strongly correlated with continuing to work in this way after graduation.

Ensemble Grouping Strategies for Embedded Stochastic Collocation Methods Applied to Anisotropic Diffusion Problems

Automated Illustration of Molecular Flexibility.

PubMed

Bryden, A; Phillips, George N; Gleicher, M

2012-01-01

In this paper, we present an approach to creating illustrations of molecular flexibility using normal mode analysis (NMA). The output of NMA is a collection of points corresponding to the locations of atoms and associated motion vectors, where a vector for each point is known. Our approach abstracts the complex object and its motion by grouping the points, models the motion of each group as an affine velocity, and depicts the motion of each group by automatically choosing glyphs such as arrows. Affine exponentials allow the extrapolation of nonlinear effects such as near rotations and spirals from the linear velocities. Our approach automatically groups points by finding sets of neighboring points whose motions fit the motion model. The geometry and motion models for each group are used to determine glyphs that depict the motion, with various aspects of the motion mapped to each glyph. We evaluated the utility of our system in real work done by structural biologists both by utilizing it in our own structural biology work and quantitatively measuring its usefulness on a set of known protein conformation changes. Additionally, in order to allow ourselves and our collaborators to effectively use our techniques we integrated our system with commonly used tools for molecular visualization.

McGuire, K.; Retter, M.; Freer, J.; Troch, P.; McDonnell, J.

2006-05-01

The International Association of Hydrological Sciences (IAHS) decade on Prediction in Ungauged Basins (PUB) has the scientific goal to shift hydrology from calibration reliant models to new and rich understanding- based models. To support this, six PUB science themes have been developed under the PUB Science Steering group. Theme 1 covers basin inter-comparison and classification. The SLope InterComparison Experiment (SLICE) is a newly-formed working group aligned with theme 1. Its 2- year target is to promote the improved understanding of regional hydrological characteristics via hillslope inter- comparison studies and top-down analysis of data from hillslope experiments from around the world. It will further deliver the major building blocks of a catchment classification system. A first workshop of SLICE took place 26-28 September 2005 at the HJ Andrews Experimental Forest, Oregon, USA. 40 participants from seven countries were in attendance. The program consisted of keynote presentations on the state-of-the-art of hillslope hydrology, outlining a hillslope classification system, and through small group discussion, a focus on the following questions: a.) How can we capture flow path heterogeneity at the hillslope scale with residence time distributions? b.) Can networks help characterize hillslope subsurface systems? c.) What patterns are useful to characterize in a hillslope comparison context? d.) How does bedrock permeability condition hillslope response? e.) Can we actually observe pressure waves in the field and/or how likely are they to exist at the hillslope continuum scale? The poster presents an overview of the workshop outcomes and directions of future work.

Students as teachers in an anatomy dissection course.

Salomäki, Tiina; Laakkonen, Juha; Ruohoniemi, Mirja

2014-01-01

One way to improve students' learning outcomes and well-being is to change teaching practices to allow students to become more active participants. We used an anatomy dissection course to test a cooperative group work method in which first-year veterinary students took turns leading their peer group and were each responsible for teaching the anatomy of a particular topographic region. The important blood vessels, lymphatic system, and nerves of each region of the body were covered. Students felt that exploration of the entire topographic region helped them to acquire a comprehensive understanding of the respiratory apparatus and the cardiovascular and nervous systems. Assigning individual tasks to each group member resulted in sharing the workload equally. Open-ended comments revealed that support from other group members was important for the students' learning experience, but the results also offered insight into a lack of constructive criticism. While teaching was considered challenging, and even a stress factor that hindered learning for some students, group work was generally held to be supportive of learning. The results suggest that more thorough instruction of students in their group work and in their individual tasks is required. Some students experienced difficulty in expressing their concerns openly and in seeking guidance from teachers, demonstrating the need for further investigation regarding students' self-regulation skills. Comments from the open-ended responses suggest that use of a cooperative learning method in anatomy dissection courses not only deepens student understanding of a subject but also offers first-year students an opportunity to practice the generic skills that will be needed in their future profession.

Using activity-based costing to track resource use in group practices.

PubMed

Zeller, T L; Siegel, G; Kaciuba, G; Lau, A H

1999-09-01

Research shows that understanding how resources are consumed can help group practices control costs. An American Academy of Orthopaedic Surgeons study used an activity-based costing (ABC) system to measure how resources are consumed in providing medical services. Teams of accounting professors observed 18 diverse orthopedic surgery practices. The researchers identified 17 resource-consuming business processes performed by nonphysician office staff. They measured resource consumption by assigning costs to each process according to how much time is spent on related work activities. When group practices understand how their resources are being consumed, they can reduce costs and optimize revenues by making adjustments in how administrative and clinical staff work.

Aligning Leadership Across Systems and Organizations to Develop Strategic Climate to for Evidence-Based Practice Implementation

Aarons, Gregory A.; Farahnak, Lauren R.; Ehrhart, Mark G.; Sklar, Marisa

2015-01-01

There has been a growing impetus to bridge the gap between basic science discovery, development of evidence-based practices (EBPs) and their availability and delivery in order to improve public health impact of such practices. In seeking to capitalize on factors that support implementation and sustainment of EBPs, it is important to consider that healthcare is delivered within the outer context of public health systems, and the inner context of healthcare organizations and workgroups. Leaders have a key role in determining the nature of system and organizational context. This article will addresses the role of leadership across levels in developing strategic climate for EBP implementation within the outer (i.e., system) and inner (i.e., organization, work group) contexts of healthcare. Within the framework of Edgar Schein’s “climate embedding mechanisms,” we describe strategies that leaders at the system, organization, and work group levels can consider and apply to develop a strategic climates that support the implementation and sustainment of EBP in healthcare and allied healthcare settings.

Creaming and Parking in Quasi-Marketised Welfare-to-Work Schemes: Designed Out Of or Designed In to the UK Work Programme?

PubMed

Carter, Eleanor; Whitworth, Adam

2015-04-01

'Creaming' and 'parking' are endemic concerns within quasi-marketised welfare-to-work (WTW) systems internationally, and the UK's flagship Work Programme for the long-term unemployed is something of an international pioneer of WTW delivery, based on outsourcing, payment by results and provider flexibility. In the Work Programme design, providers' incentives to 'cream' and 'park' differently positioned claimants are intended to be mitigated through the existence of nine payment groups (based on claimants' prior benefit type) into which different claimants are allocated and across which job outcome payments for providers differ. Evaluation evidence suggests however that 'creaming' and 'parking' practices remain common. This paper offers original quantitative insights into the extent of claimant variation within these payment groups, which, contrary to the government's intention, seem more likely to design in rather than design out 'creaming' and 'parking'. In response, a statistical approach to differential payment setting is explored and is shown to be a viable and more effective way to design a set of alternative and empirically grounded payment groups, offering greater predictive power and value-for-money than is the case in the current Work Programme design.

Cultivating a Network For Messaging About Climate Change Across an Urban System

NASA Astrophysics Data System (ADS)

Wertheim, J.

2014-12-01

Currently, some of the most promising efforts to address climate change are taking place at the scale of cities and municipalities. Large urban areas host an active population of organizations working to influence local environmental policies more rigorous than those at the state and national level. The composition of these groups is broadening as impacts of climate change are being recognized as relevant to more sectors within urban systems, from health centers to community leaders, leading more organizations to consider how they can raise awareness and gain support for their needs. The National Geographic Society, as part of the National Science Foundation (NSF)-funded Climate and Urban Systems Partnership (CUSP), has convened a pilot "community of practice" (CoP) consisting of organizations working at the local level in Washington, DC to communicate with audiences, from the general public to local government agencies, about ways that climate change is predicted to affect the city and what can be done about it. The purpose of the CoP was initially to help these groups coordinate their activities, share knowledge and resources, and to create a platform for ongoing collaborative learning. While the CoP is still evolving, it is clear that it has potential to provide even deeper and more meaningful support to these groups' efforts. Developing effective messaging about climate change across an urban system depends on the valuable insight these groups have into their audience's interests, beliefs, and knowledge, but it also requires a set of competencies that few members of the CoP hold. As conveners of the CoP, we have identified and prioritized those competencies and are developing a process for training CoP members to apply their expertise to implement empirically-based best practices in climate change messaging, public communication, and integration of data and visualizations. The process of training the group has the potential to both create a CoP that becomes a trusted resource for climate messaging activities in DC and an enduring network of professionals who identify participating in the group's ongoing work as essential to their own professional development

Future Space Transportation Technology: Prospects and Priorities

Billie, Matt; Reed, Lisa; Harris, David

2003-01-01

The Transportation Working Group (TWG) was chartered by the NASA Exploration Team (NEXT) to conceptualize, define, and advocate within NASA the space transportation architectures and technologies required to enable the human and robotic exploration and development of space envisioned by the NEXT. In 2002, the NEXT tasked the TWG to assess exploration space transportation requirements versus current and prospective Earth-to-Orbit (ETO) and in-space transportation systems, technologies, and research, in order to identify investment gaps and recommend priorities. The result was a study now being incorporated into future planning by the NASA Space Architect and supporting organizations. This paper documents the process used to identify exploration space transportation investment gaps, as well as the group's recommendations for closing these gaps and prioritizing areas of future investment for NASA work on advanced propulsion systems.

This report continues the practice where the IAU Working Group on Cartographic Coordinates and Rotational Elements revises recommendations regarding those topics for the planets, satellites, minor planets, and comets approximately every 3 years. The Working Group has now become a "functional working group" of the IAU, and its membership is open to anyone interested in participating. We describe the procedure for submitting questions about the recommendations given here or the application of these recommendations for creating a new or updated coordinate system for a given body. Regarding body orientation, the following bodies have been updated: Mercury, based on MESSENGER results; Mars, along with a refined longitude definition; Phobos; Deimos; (1) Ceres; (52) Europa; (243) Ida; (2867) Šteins; Neptune; (134340) Pluto and its satellite Charon; comets 9P/Tempel 1, 19P/Borrelly, 67P/Churyumov-Gerasimenko, and 103P/Hartley 2, noting that such information is valid only between specific epochs. The special challenges related to mapping 67P/Churyumov-Gerasimenko are also discussed. Approximate expressions for the Earth have been removed in order to avoid confusion, and the low precision series expression for the Moon's orientation has been removed. The previously online only recommended orientation model for (4) Vesta is repeated with an explanation of how it was updated. Regarding body shape, text has been included to explain the expected uses of such information, and the relevance of the cited uncertainty information. The size of the Sun has been updated, and notation added that the size and the ellipsoidal axes for the Earth and Jupiter have been recommended by an IAU Resolution. The distinction of a reference radius for a body (here, the Moon and Titan) is made between cartographic uses, and for orthoprojection and geophysical uses. The recommended radius for Mercury has been updated based on MESSENGER results. The recommended radius for Titan is returned to its previous value. Size information has been updated for 13 other Saturnian satellites and added for Aegaeon. The sizes of Pluto and Charon have been updated. Size information has been updated for (1) Ceres and given for (16) Psyche and (52) Europa. The size of (25143) Itokawa has been corrected. In addition, the discussion of terminology for the poles (hemispheres) of small bodies has been modified and a discussion on cardinal directions added. Although they continue to be used for planets and their satellites, it is assumed that the planetographic and planetocentric coordinate system definitions do not apply to small bodies. However, planetocentric and planetodetic latitudes and longitudes may be used on such bodies, following the right-hand rule. We repeat our previous recommendations that planning and efforts be made to make controlled cartographic products; newly recommend that common formulations should be used for orientation and size; continue to recommend that a community consensus be developed for the orientation models of Jupiter and Saturn; newly recommend that historical summaries of the coordinate systems for given bodies should be developed, and point out that for planets and satellites planetographic systems have generally been historically preferred over planetocentric systems, and that in cases when planetographic coordinates have been widely used in the past, there is no obvious advantage to switching to the use of planetocentric coordinates. The Working Group also requests community input on the question submitting process, posting of updates to the Working Group website, and on whether recommendations should be made regarding exoplanet coordinate systems.

[PSYCHO PHYSIOLOGICAL MARKERS OF ACCELERATED AGING AMONG THOSE WORKING WITH OCCUPATIONAL HAZARDS].

We assessed the significance of psycho physiological markers of accelerated aging of the function of attention using comparative analysis of two occupational groups in order to reveal how the working process affects mental work capacity. We revealed peculiarities of systemic structure of functions which determine mental work capacity depending on the age and length of service in lorry drivers. It was proved that decrease in the mnestic functions of lorry-drivers takes place 10-15 years earlier compared to the control group. Psycho physiological indices, reflecting the functioning of attention, decreased not only with aging but also with longer driving experience. Our results show that it is necessary to conduct further studies of psycho physiological markers of age-related decrease in short-term memory depending on the activities at work in order to prevent accelerated aging and achieve professional longevity.

There has been a recent proposal to change the grading system of prostate cancer into a five-tier grade grouping system. The prognostic impact of this has been demonstrated in regards only to biochemical recurrence-free survival (bRFS) with short follow-up (3 years). Between 1990 and 2013, 847 consecutive men were treated with definitive external beam radiation therapy at a single academic center. To validate the new grade grouping system, bRFS, distant metastases-free survival (DMFS) and prostate cancer-specific survival (PCSS) were calculated. Adjusted Kaplan-Meier and multivariable Cox regression analyses were performed to assess the independent impact of the new grade grouping system. Discriminatory analyses were performed to compare the commonly used three-tier Gleason score system (6, 7 and 8-10) to the new system. The median follow-up of our cohort was 88 months. The 5-grade groups independently validated differing risks of bRFS (group 1 as reference; adjusted hazard ratio (aHR) 1.35, 2.16, 1.79 and 3.84 for groups 2-5, respectively). Furthermore, a clear stratification was demonstrated for DMFS (aHR 2.03, 3.18, 3.62 and 13.77 for groups 2-5, respectively) and PCSS (aHR 3.00, 5.32, 6.02 and 39.02 for groups 2-5, respectively). The 5-grade group system had improved prognostic discrimination for all end points compared with the commonly used three-tiered system (that is, Gleason score 6, 7 and 8-10). In a large independent radiotherapy cohort with long-term follow-up, we have validated the bRFS benefit of the proposed five-tier grade grouping system. Furthermore, we have demonstrated that the system is highly prognostic for DMFS and PCSS. Grade group 5 had markedly worse outcomes for all end points, and future work is necessary to improve outcomes in these patients.

Siddiqi, Shahid; Vosteen, Louis F.; Edlow, Ralph; Kwa, Teck-Seng

1992-01-01

An automated data abstraction form (ADAF) was developed to collect information on advanced fabrication processes and their related costs. The information will be collected for all components being fabricated as part of the ACT program and include in a COmposites INformation System (COINS) database. The aim of the COINS development effort is to provide future airframe preliminary design and fabrication teams with a tool through which production cost can become a deterministic variable in the design optimization process. The effort was initiated by the Structures Technology Program Office (STPO) of the NASA LaRC to implement the recommendations of a working group comprised of representatives from the commercial airframe companies. The principal working group recommendation was to re-institute collection of composite part fabrication data in a format similar to the DOD/NASA Structural Composites Fabrication Guide. The fabrication information collection form was automated with current user friendly computer technology. This work in progress paper describes the new automated form and features that make the form easy to use by an aircraft structural design-manufacturing team.

The government of India has done remarkable work on commissioning a government funded prehospital emergency ambulance service in India. This has both public health implications and an economic impact on the nation. With the establishment of these services, there is an acute need for standardization of education and quality assurance regarding prehospital care provided. The International Joint Working Group has been actively involved in designing guidelines and establishing a comprehensive framework for ensuring high-quality education and clinical standards of care for prehospital services in India. This paper provides an independent expert opinion and a proposed framework for general operations and administration of a standardized, national prehospital emergency medical systems program. Program implementation, operational details, and regulations will require close collaboration between key stakeholders, including local, regional, and national governmental agencies of India.

Case managers within injury compensation systems are confronted with various emotional demands. Employing the concept of emotional labour, this paper explores distinctive aspects of these demands. The findings are drawn from focus groups with 21 Australian case managers. Case managers work was characterised by extra-role commitments, emotional control, stress and balancing tensions arising from differing stakeholder expectations about outcomes related to compensation and return to work. By examining the experiences of case managers, the findings add to the literature on the emotional labour of front line service workers, especially with respect to the demands involved in managing the conflicting demands of work.

There have been few studies of work history and mortality risks in medical radiation workers. We expanded by 11 years and more outcomes our previous study of mortality risks and work history, a proxy for radiation exposure. Using Cox proportional hazards models, we estimated mortality risks according to questionnaire work history responses from 1983 to 1989 through 2008 by 90,268 US radiological technologists. We controlled for potential confounding by age, birth year, smoking history, body mass index, race and gender. There were 9566 deaths (3329 cancer and 3020 circulatory system diseases). Mortality risks increased significantly with earlier year began working for female breast (p trend=0.01) and stomach cancers (p trend=0.01), ischaemic heart (p trend=0.03) and cerebrovascular diseases (p trend=0.02). The significant trend with earlier year first worked was strongly apparent for breast cancer during baseline through 1997, but not 1998-2008. Risks were similar in the two periods for circulatory diseases. Radiological technologists working ≥5 years before 1950 had elevated mortality from breast cancer (HR=2.05, 95% CI 1.27 to 3.32), leukaemia (HR=2.57, 95% CI 0.96 to 6.68), ischaemic heart disease (HR=1.13, 95% CI 0.96 to 1.33) and cerebrovascular disease (HR=1.28, 95% CI 0.97 to 1.69). No other work history factors were consistently associated with mortality risks from specific cancers or circulatory diseases, or other conditions. Radiological technologists who began working in early periods and for more years before 1950 had increased mortality from a few cancers and some circulatory system diseases, likely reflecting higher occupational radiation exposures in the earlier years.

An Overview of My 2004 Summer Internship

NASA Technical Reports Server (NTRS)

Hertert, Lucien

2004-01-01

This summer I have been working with the Non-destructive evaluation (NDE) group and NASA Glenn Research Center. As this is my second summer with the group, I was able to begin working as soon as I arrived. My first task was to develop a system to acquire an impedance analyzer. The basic setup of the system is as follows: a piezo- electric patch is attached to a sample, and a lead is attached to that patch. Another lead is attached directly to the sample, and the leads are connected to the impedance analyzer. The system then puts a voltage through the material over a range of frequencies, and the corresponding impedances are measured for each frequency. After data is collected, it can be compared to another data set, and through a series of calculations a damage parameter is produced. For the time being, we are using a correlation calculation to find the damage parameter. The hope for this project is that a baseline measurement can be taken, and then sometime later another measurement could be taken, and the damage parameter would determine how much damage had been done to the sample. To test this hypothesis, we took baseline data from a sample, and then sent it out to have a notch cut into it. When it was returned, we again took measurements on the sample, and the damage parameter was significantly lower. Another project that I have been working on pertains to the group's newly acquired acoustography system. This system creates a full field ultrasonic signal on one side of a sample, and an acousto-optic sensor is placed on the other side of the sample.

Density matrix renormalization group for a highly degenerate quantum system: Sliding environment block approach

NASA Astrophysics Data System (ADS)

Schmitteckert, Peter

2018-04-01

We present an infinite lattice density matrix renormalization group sweeping procedure which can be used as a replacement for the standard infinite lattice blocking schemes. Although the scheme is generally applicable to any system, its main advantages are the correct representation of commensurability issues and the treatment of degenerate systems. As an example we apply the method to a spin chain featuring a highly degenerate ground-state space where the new sweeping scheme provides an increase in performance as well as accuracy by many orders of magnitude compared to a recently published work.

Quality management and work environment in Swedish oral and maxillofacial surgery.

2009-01-01

This thesis attempts to describe the opinion of the work with quality, quality management, and work environment among the employees at Oral and Maxillofacial Surgery (OMFS) clinics in Sweden. Analyse if the OMFS clinics in Sweden actively work with quality development and if so which systems they use. Explore the opinion of the employees about quality work. Describe how the employees of OMFS clinics in Sweden perceive good work, i.e., their image of the dimensions that the profession should contain to be really good work. Investigate whether there is a discrepancy between ideal and reality for this group. Describe how the employees of OMFS clinics in Sweden perceive their health. Analyse how work environment influenced attitudes to and knowledge of quality among employees of OMFS clinics in Sweden. The study was based on self-report questionnaires which in 2003 were sent to all OMFS clinics in Sweden. The response rate was 86%. Only at two clinics did all the respondents agree on their system. Surgeons rated intellectually stimulating work as most important, and the hazard-free work environment as least important. The nurses rated stimulating fellowship as most important, and the opportunity for career advancement as least important. The percentage unit differences between the ideal and the reality were largest for the item the work provides opportunities to have an influence on important decisions. There were significant differences between maxillofacial. surgeons and dental nurses and assistant nurses as to muscle- and joint trouble. The differences were also significant between men and women both as to muscle- and joint troubles and somatic trouble. Only work environment was significant for attitude towards quality work. Profession, gender, clinic size, and a factor for hard demand had significant associations to quality management system used or not. More than half of the respondents stated that they worked with a quality system. The dental nurses and assistant nurses had a much more positive view on the potential of quality work as a means to improve their work than had the maxillo-facial surgeons. For a majority of the dental nurses the working situation concerning the physical environment was more important than for the maxillo-facial surgeons. The employees emphasized free, influential, and intellectually stimulating work, but the dissonance between ideal and reality was rather wide concerning good work. OMFS employees are feeling unhealthy, but no worse than other high-risk-groups in human service working and better than female general practice dentists. The women of OMFS employees feel worse than the men.

This paper studies and assesses how rehabilitation activities and supervised computer games incorporated into a system aimed at people diagnosed with Autism Spectrum Disorder (ASD) can be used to work on the areas affected by ASD at any time and in any place. This research specifically assesses the areas that affect communication and interaction between people with ASD and professionals. In order to do this, a group of 20 children diagnosed with ASD of between 3 and 8 years old (clinical group) was used, together with a group of 20 children of between 3 and 8 years old with a neurotypical development, which served as a control group. During the tests, response time and visual interaction with the session leader were evaluated. Despite the fact that the clinical group spent more time (M = 21.08 sec) than the control group (M = 4.52) to interact leader, eye contact predominated in the interaction. As a result of the pilot study, the system obtained could help in cognitive rehabilitation.

To evaluate the feasibility and efficacy of a fully integrated hybrid closed-loop (HCL) system (Medtronic MiniMed Inc., Northridge, CA), in day and night closed-loop control in subjects with type 1 diabetes, both in an inpatient setting and during 6 days at diabetes camp. The Medtronic MiniMed HCL system consists of a fourth generation (4S) glucose sensor, a sensor transmitter, and an insulin pump using a modified proportional-integral-derivative (PID) insulin feedback algorithm with safety constraints. Eight subjects were studied over 48 h in an inpatient setting. This was followed by a study of 21 subjects for 6 days at diabetes camp, randomized to either the closed-loop control group using the HCL system or to the group using the Medtronic MiniMed 530G with threshold suspend (control group). The overall mean sensor glucose percent time in range 70-180 mg/dL was similar between the groups (73.1% vs. 69.9%, control vs. HCL, respectively) (P = 0.580). Meter glucose values between 70 and 180 mg/dL were also similar between the groups (73.6% vs. 63.2%, control vs. HCL, respectively) (P = 0.086). The mean absolute relative difference of the 4S sensor was 10.8 ± 10.2%, when compared with plasma glucose values in the inpatient setting, and 12.6 ± 11.0% compared with capillary Bayer CONTOUR NEXT LINK glucose meter values during 6 days at camp. In the first clinical study of this fully integrated system using an investigational PID algorithm, the system did not demonstrate improved glucose control compared with sensor-augmented pump therapy alone. The system demonstrated good connectivity and improved sensor performance. © 2015 by the American Diabetes Association.

In order to address the challenges facing the community-based health workforce in Zambia, the Ministry of Health implemented the national community health assistant strategy in 2010. The strategy aims to address the challenges by creating a new group of workers called community health assistants (CHAs) and integrating them into the health system. The first group started working in August 2012. The objective of this paper is to document their motivation to become a CHA, their experiences of working in a rural district, and how these experiences affected their motivation to work. A phenomenological approach was used to examine CHAs' experiences. Data collected through in-depth interviews with 12 CHAs in Kapiri Mposhi district and observations were analysed using a thematic analysis approach. Personal characteristics such as previous experience and knowledge, passion to serve the community and a desire to improve skills motivated people to become CHAs. Health systems characteristics such as an inclusive work culture in some health posts motivated CHAs to work. Conversely, a non-inclusive work culture created a social structure which constrained CHAs' ability to learn, to be innovative and to effectively conduct their duties. Further, limited supervision, misconceptions about CHA roles, poor prioritisation of CHA tasks by some supervisors, as well as non- and irregular payment of incentives also adversely affected CHAs' ability to work effectively. In addition, negative feedback from some colleagues at the health posts affected CHA's self-confidence and professional outlook. In the community, respect and support provided to CHAs by community members instilled a sense of recognition, appreciation and belonging in CHAs which inspired them to work. On the other hand, limited drug supplies and support from other community-based health workers due to their exclusion from the government payroll inhibited CHAs' ability to deliver services. Programmes aimed at integrating community-based health workers into health systems should adequately consider multiple incentives, effective management, supervision and support from the district. These should be tailored towards enhancing the individual, health system and community characteristics that positively impact work motivation at the local level if such programmes are to effectively contribute towards improved primary healthcare.

2014-05-01

The Ramboll Group is a large (10.000 employees worldwide) engineering and consultancy company, with offices in 21 countries. Ramboll has been working with geophysics for about 20 years and at the time of writing there are about 25 geophysicist employed in the group, 20 of these are employed in Ramboll Denmark. Ramboll offers an extensive range of geophysical methods: different types of seismic, borehole wireline logging, electric and electromagnetic surveys, magnetic resonance soundings and well as marine geophysical and hydrographic surveys. The geophysical group at Ramboll operates in different industries comprising: Infrastructure, environmental assessments, mineral exploration, energy and offshore constructions. In the recent years our GPR activities has increased significantly. Today Ramboll Denmark owns three separate GPR systems: One GSSI SIR-3000 with antennas ranging from 16MHz to 2GHz, One Mala geoscience ProEx system with a 100MHz RTA antenna and one 3D-radar Geoscope MKIV system with two DX antennas of different size. The main services are geological mapping with our ProEx system from Malå Geoscience, road mapping with a GSSI system and different shallow mapping with our 3D system from 3D Radar. With our 2D systems we have performed mapping of peat in different places in Norway, mapping of sediments at various places in the Nordic countries and mapping of glacier thickness in Greenland. In this type of investigations we often combine GPR with resistivity imaging (CVES) and refraction seismic to ensure a more reliable interpretation. We have performed occasional utility or UXO surveys where GPR has been used together with EM or magnetic measurements. The mapping on roads with the GSSI system is performed by our RST (Road Surface Testing) department in Malmö, Sweden. The measurements on roads are often combined with laser scanning and photo registration of the surface. Various software have been developed to automatize the interpretation. The RST group has contributed to aninternational collaboration between several countries about preparation of guidelines for application of GPR on roads, the Mara Nord Project. Our 3D system is used for various types of surveys. In airports mapping has been performed both on runways, taxiways and aprons with the aim of mapping layer thicknesses and delamination for planning of maintenance work. Acquisition has also been done on roads for control of asphalt works and mapping of the road bed. On bridges mapping of rebars and structure has been performed. The 3D system is also used for determination of space behind frost insulation walls in tunnels in Norway. This work is based on a pilot project made by SINTEF in Norway. This abstract is a contribution to COST Action TU1208.

Study of lnter-Molecular Dynamics within Alkylsiloxane Self-Assembled Monolayer and Elastomer Systems

NASA Astrophysics Data System (ADS)

Roman, Michael

In this work, molecular motion, and in particular, glassy relaxations are studied in two novel experimental systems. Both experimental systems offer a significant degree of control over molecule-molecule, or group-group (where group refers to a portion of a molecule), interactions by controlling density and the type of inter-molecular interaction. Both systems have rigid elements that decrease the tendency of bulk materials to spontaneously change their density with temperature. Thus, density can be maintained and controlled and the effect of density and temperature can be (at least in part) de-convolved. The goal of this work is to experimentally observe the transition from simple, local relaxations to glassy dynamics as density is increased and to understand how this transition differs as the inter-molecular interactions are altered. In both approaches, the system is fabricated from individual parts where the nature, spacing, and particular arrangement of the parts can be controlled and the resultant changes in molecular motion can be observed. Building up a custom system from parts enables fundamental investigation into the glass transition (as discussed above) and also makes possible the development of materials that have engineered responses as a function of temperature. As a short-hand, we refer to the two systems as the monolayer or SAM (short for Self-Assembled Monolayer) and elastomer approaches. In Chapters 4-7 we discuss results from the monolayer approach. Chapter 8 summarizes results from the elastomer approach. In particular, Chapter 4 introduces you to dielectric spectroscopy and briefly summarizes the previous work by former students in the Clarke group which identified the local and glass relaxations in silane monolayers of substituted alkyl chains as analogous to the local and glassy relaxations in polymeric systems containing phase segregated alkyl chains, and similar to the local and glass modes in poly(ethylene). The remainder of Chapter 4 summarizes my own work to clearly delineate the transition from non-interacting behavior at low density (a partially-filled monolayer) to glassy behavior (with or without the presence of a local mode) as density is increased. In Chapter 5, I determined that this transition is highly robust to sample preparation technique. In Chapter 6, the effect of different inter-molecular interactions (dipole strength) on this transition and the resultant glassy state is discussed. Chapter 7 discusses changes in the local modes and the distribution of local and glass modes in the system as a function of terminal dipole strength. In chapter 8, elastomers are studied and the effect of backbone composition and distance between crosslinks is shown. This elastomer system can serve as a new substrate on which similar experiments as conducted with mono layers can be undertaken.

Improper use of sense organs, violating the moral code of conduct, and the effect of the time are the three basic causative factors behind all the health problems. Computer, the knowledge bank of modern life, has emerged as a profession causing vision-related discomfort, ocular fatigue, and systemic effects. Computer Vision Syndrome (CVS) is the new nomenclature to the visual, ocular, and systemic symptoms arising due to the long time and improper working on the computer and is emerging as a pandemic in the 21(st) century. On critical analysis of the symptoms of CVS on Tridoshika theory of Ayurveda, as per the road map given by Acharya Charaka, it seems to be a Vata-Pittaja ocular cum systemic disease which needs systemic as well as topical treatment approach. Shatavaryaadi Churna (orally), Go-Ghrita Netra Tarpana (topically), and counseling regarding proper working conditions on computer were tried in 30 patients of CVS. In group I, where oral and local treatment was given, significant improvement in all the symptoms of CVS was observed, whereas in groups II and III, local treatment and counseling regarding proper working conditions, respectively, were given and showed insignificant results. The study verified the hypothesis that CVS in Ayurvedic perspective is a Vata-Pittaja disease affecting mainly eyes and body as a whole and needs a systemic intervention rather than topical ocular medication only.

To investigate the working patterns and patient base of registered clinical dental technicians (CDTs); their relationships with dentists and other professionals in the dental team; their willingness to work within the NHS and their expectations for the future as a new professional group. Face-to-face qualitative interviews of registered CDTs, selected because of their geographic representation and mode of working, informed the development of a postal questionnaire survey of all early registrants with the General Dental Council (GDC). The majority of CDTs reported working part-time, often combining clinical practice with their role as a dental technician. They reported both positive and negative working relationships with dentists and dental technicians, demonstrating collaboration and/or competition depending on whether the scope of CDTs was respected and patient care was shared or lost. CDTs role in the NHS was limited because they did not have the status of becoming a recognised provider of dental care. There was a desire to expand their scope of practice in future. CDTs are embracing their new status as an occupational group within dentistry. Core features of becoming a professional group were exhibited including the importance of social and financial status and the need to negotiate their current and future roles in the healthcare system.

Operational experience with DICOM for the clinical specialties in the healthcare enterprise

A number of clinical specialties routinely use images in treating patients, for example ophthalmology, dentistry, cardiology, endoscopy, and surgery. These images are captured by a variety of commercial digital image acquisition systems. The US Department of Veterans Affairs has been working for several years on advancing the use of the Digital Imaging and Communications in Medicine (DICOM) Standard in these clinical specialties. This is an effort that has involved several facets: (1) working with the vendors to ensure that they satisfy existing DICOM requirements, (2) developing interface software to the VistA hospital information system (HIS), (3) field testing DICOM systems, (4) deploying these DICOM interfaces nation-wide to all VA medical centers, (5) working with the healthcare providers using the system, and (6) participating in the DICOM working groups to improve the standard. The VA is now beginning to develop clinical applications that make use of the DICOM interfaces in the clinical specialties. The first of these will be in ophthalmology to remotely screen patients for diabetic retinopathy.

NASA's Earth Science Data Systems Working Groups (ESDSWG) was created over 10 years ago. The role of the ESDSWG is to make recommendations relevant to NASA's Earth science data systems from user experiences. Each group works independently focusing on a unique topic. Participation in ESDSWG groups comes from a variety of NASA-funded science and technology projects, such as MEaSUREs, NASA information technology experts, affiliated contractor, staff and other interested community members from academia and industry. Recommendations from the ESDSWG groups will enhance NASA's efforts to develop long term data products. Each year, the ESDSWG has a face-to-face meeting to discuss recommendations and future efforts. Last year's (2014) ASCII for Science Data Working Group (ASCII WG) completed its goals and made recommendations on a minimum set of information that is needed to make ASCII files at least human readable and usable for the foreseeable future. The 2014 ASCII WG created a table of ASCII files and their components as a means for understanding what kind of ASCII formats exist and what components they have in common. Using this table and adding information from other ASCII file formats, we will discuss the advantages and disadvantages of a standardized format. For instance, Space Geodesy scientists have been using the same RINEX/SINEX ASCII format for decades. Astronomers mostly archive their data in the FITS format. Yet Earth scientists seem to have a slew of ASCII formats, such as ICARTT, netCDF (an ASCII dump) and the IceBridge ASCII format. The 2015 Working Group is focusing on promoting extendibility and machine readability of ASCII data. Questions have been posed, including, Can we have a standardized ASCII file format? Can it be machine-readable and simultaneously human-readable? We will present a summary of the current used ASCII formats in terms of advantages and shortcomings, as well as potential improvements.

Improving rates of screening and prevention by leveraging existing information systems.

In 1997 Virginia Mason Health System (VMMC), a vertically integrated hospital and multispecialty group practice, had no process or system to deliver the right patient clinical data, in the right form, at the right place--when providers needed it for effective patient care. Without any new investment in technology, a work group of five individuals leveraged existing, primarily paper-based information systems to launch development and implementation of a provider prompting tool--a primary care and prevention (PCP) report--which prompted providers to complete screening, prevention, and disease management services at every patient appointment. The work group developed and pilot tested the report and created a mechanism by which the report could be delivered just in time before each patient's appointment. The report integrated information from independent appointment scheduling, laboratory results reporting, patient demographics, and billing data sources. MEASURING THE PCP REPORT'S IMPACT: The results of two separate analyses demonstrate improvement in rates of screening and prevention across VMMC soon after the PCP report became available. These results led senior leadership to make the PCP report's utilization a systemwide imperative. The PCP report is used by nearly all primary care providers as a prompt to complete screening, prevention, and disease management services at every patient appointment.

The aim of the survey was to analyze the efficacy of physiotherapy applied in coal miners as well as to assess their locomotor system load and the effects of working conditions in mines. The questionnaire survey covered a group of 51 miners, aged 28-76 years (mean, 54 years), undergoing physiotherapeutic procedures in the mine out-patient clinic during the first quarter of 2003. The survey revealed that lumbosacral disorders were the most frequent locomotor system complaints reported by miners, especially those who work in a bending down position. According to the clinical data, spondylosis and allied disorders were the main reasons for pain in this part of the body. Having analyzed the relationship between age and occurrence of back pains, the majority of complaints were found in the 46-55 age group (two complaints per one respondent). The analysis of the association between back pains and duration of employment revealed that the complaints for the locomotor system occurred already after a five-year employment. The survey showed that the application of physiotherapeutic procedures diminished the back pain in the study group by 2.83 on average on the 0-10 scale. It was also found that magnetotherapy proved to be the most effective method in treating the spinal degenerative changes.

The aim of this study is to compare and to evaluate sealing ability of newly introduced C-point system, cold lateral condensation, and thermoplasticized gutta-percha obturating technique using a dye extraction method. Sixty extracted maxillary central incisors were decoronated below the cementoenamel junction. Working length was established, and biomechanical preparation was done using K3 rotary files with standard irrigation protocol. Teeth were divided into three groups according to the obturation protocol; Group I-Cold lateral condensation, Group II-Thermoplasticized gutta-percha, and Group III-C-Point obturating system. After obturation all samples were subjected to microleakage assessment using dye extraction method. Obtained scores will be statistical analyzed using ANOVA test and post hoc Tukey's test. One-way analysis of variance revealed that there is significant difference among the three groups with P value (0.000 < 0.05). Tukey's HSD post hoc tests for multiple comparisons test shows that the Group II and III perform significantly better than Group I. Group III performs better than Group II with no significant difference. All the obturating technique showed some degree of microleakage. Root canals filled with C-point system showed least microleakage followed by thermoplasticized obturating technique with no significant difference among them. C-point obturation system could be an alternative to the cold lateral condensation technique.

Bulk transmission system component outage data base. Research project 1283-1. Final report

This project is responsive to the premise that the successful analysis of equipment reliability and system adequacy in bulk transmission system planning and system operations requires data on equipment failure rates, maintenance outage rates and repair times. The objective of the project is to develop a system of consistent definitions, formats and procedures which can be used in the collection of such data in a well designed outage data bank. The project consisted of four interrelated phases, beginning with a review of related work and problem definition and ending with a discussion of data base organization and management. The reviewmore » of related work quickly pointed out that two schools of thought exist on data collection. One group contends that data should be collected on bulk transmission system physical equipments, such as transformers, circuit breakers, etc., and the other group supports data collection on functional transmission lines, including the terminal equipment, which have been defined as transmission units in this report. A compromise between these two approaches was imperative for successful completion of the work. The second phase investigated the data needed for reliability evaluation. The applications of the data bank were enumerated leading to a list of basic data needed when recording an incident. Phase 3 concentrated on developing procedures for data collection using forms to collect data both on outages and on the equipment design. Finally, the aspects of data base organization and management were explored and general recommendations made appropriate to this specific application. The project did not succeed in completely defining the procedures, particularly for multiple outages, but the ground work has been laid for a pilot data collection effort to refine the procedures before wide scale implementation by the utility industry.« less

We investigated circadian changes and effects on mood, sleep-related hormones and cognitive performance when nurses worked consecutive night shifts in a rapidly rotating shift system. Daytime cognitive function, sleep propensity and sleep-related hormones (growth hormone, cortisol, prolactin, thyrotropin) were compared after participants worked two and four consecutive night shifts. Twenty-three off-duty nurses, 20 nurses working two consecutive night shifts and 16 nurses working four consecutive night shifts were enrolled. All participants completed the Maintenance of Wakefulness Test, State-Trait Anxiety Inventory, Stanford Sleepiness Scale, visual attention tasks (VAT), Wisconsin Card Sorting Test, and modified Multiple Sleep Latency Test. Hormone levels were also measured four times throughout the day, at 2-h intervals. During the day, the participants in the night shift groups were less able to maintain wakefulness, had poor performance on VAT, and higher thyrotropin levels than did those in the off-duty group. Participants who worked two night shifts were better able to maintain wakefulness, had higher anxiety scale scores, poorer initial performance and lack of learning effect on VAT, and higher prolactin levels compared with those who worked four night shifts. There were no differences in cortisol levels between the two- and four- shift groups. Rotating night shifts too quickly may cause anxiety and decreased attentional performance, and may impact daytime prolactin levels after night shifts. It is possible that the two-shift group had a higher cortisol level than did the four-shift group, which would be consistent with the group's higher state anxiety scores. The negative findings may be due to the small sample size. Further studies on the effects of consecutive night shifts on mood and cortisol levels during the daytime after sleep restriction would be valuable.

T-piece resuscitation systems are pressure unstable and have high imposed work of breathing (iWOB). Pressure stable respiratory support with low iWOB might improve outcome. We have developed a new resuscitation system that can be used with nasal prongs or face mask. The aim of the study was to describe the in vitro performance of the new system and to perform a clinical feasibility trial of initial stabilisation of preterm infants. A mechanical lung model was used to determine iWOB at increasing levels of continuous positive airway pressure (CPAP). The feasibility trial included 36 infants (27-34 weeks of gestation), who were randomised into three groups (T-piece, new system with face mask or new system with prongs). Collected data included problems with usage, safety, time to stable breathing, need for positive pressure ventilation and intubation. In the mechanical lung model, the new system reduced iWOB with 91.5% (mask) and 86.6% (medium prongs) compared with Neopuff (4 cm CPAP, p<0.001). Informed consent was obtained from 45 patients, 39 were randomised and 36 needed support. Randomisation resulted in an imbalance: The group of new system infants had lower gestational age compared with the T-piece group. Thirteen patients needed positive pressure ventilation (median 20 cm H 2 O). One infant was intubated. The study did not reveal problems with the equipment or safety. Compared with T-piece systems, the new system had a marked reduction in iWOB in bench tests. The feasibility trial did not reveal problems with usability or safety.

Potential for local and systemic bacterial infection in some occupational groups in Benin City, Nigeria.

Hugbo, P G; Okonkwo, J O

1992-06-01

Many Third World countries may not have adequate facilities for rapid sensitivity testing of antibiotics as an aid to diagnosis and chemotherapy. It may therefore be valuable to relate bacterial carriage on the skin to type of work a person does. Given areas of skin in workers from 10 occupational groups were sampled. The bacteria obtained were analyzed after growth on appropriate media. The sensitivity profiles of potential pathogens isolated from these groups, as well as of those (Staphylococcus aureus only) isolated from patients with certified infections, were carried out and the results were analyzed. Staphylococcus aureus constituted the most widely and frequently isolated potential pathogen. Proteus mirabilis, Escherichia coli, and Klebsiella species were also frequent colonizers of skin. There was a statistical relationship between work type and overall prevalence of bacteria on skin (p less than 0.01). Most isolates of the work groups were highly sensitive to gentamicin and cefuroxine but not to penicillin G, ampicillin, and trimethoprim plus sulfamethoxazole; isolates from infected persons were generally more resistant than were the community-acquired ones. A relationship may exist between the types of bacteria carried on the skin and the type of work in which a person is engaged.

There has been concern expressed by the UK regulator, the Health & Safety Executive, regarding the management of occupation dose for healthcare radiation workers who work across multiple organizations. In response to this concern, the British Institute of Radiology led a working group of relevant professional bodies to develop guidance in this area. The guidance addresses issues of general system management that would apply to all personal dosimetry systems, regardless of whether or not the workers within that system work across organizational boundaries, along with exploring efficient strategies to comply with legislation where those workers do indeed work across organizational boundaries. For those specific instances, the guidance discusses both system requirements to enable organizations to co-operate (Ionising Radiation Regulations 1999 Regulation 15), as well as specific instances of staff exposure. This is broken down into three categories-low, medium and high risk. A suggested approach to each is given to guide employers and their radiation advisers in adopting sensible strategies for the monitoring of their staff and the subsequent sharing of dosimetry data to ensure overall compliance with both dose limits and optimization requirements.

Aromatherapy Benefits Autonomic Nervous System Regulation for Elementary School Faculty in Taiwan

PubMed Central

Chang, Kang-Ming; Shen, Chuh-Wei

2011-01-01

Workplace stress-related illness is a serious issue, and consequently many stress reduction methods have been investigated. Aromatherapy is especially for populations that work under high stress. Elementary school teachers are a high-stress working population in Taiwan. In this study, fifty-four elementary school teachers were recruited to evaluate aromatherapy performance on stress reduction. Bergamot essential oil was used for aromatherapy spray for 10 minutes. Blood pressure and autonomic nervous system parameters were recorded 5 minutes before and after the application of the aroma spray. Results showed that there were significant decreases in blood pressure, heart rate, LF power percentage, and LF/HF while there were increases in heart rate variability and HF power percentage (P < .001∗∗∗) after application of the aromatherapy spray. Further analysis was investigated by dividing subjects into three background variables (position variables, age variables, gender variables) and anxiety degree groups. All parameters were significantly different for most subgroups, except for the substitute teachers and the light-anxiety group. Parasympathetic nervous system activation was measured after aromatherapy in this study. It encouraged further study for other stress working population by aromatherapy. PMID:21584196

The sociotechnical systems perspective offers intriguing and potentially valuable insights into problems associated with workplace safety. While formal sociotechnical systems thinking originated in the 1950s, its application to the analysis and design of sustainable, safe working environments has not been fully developed. To that end, a Hopkinton Conference was organised to review and summarise the state of knowledge in the area and to identify research priorities. A group of 26 international experts produced collaborative articles for this special issue of Ergonomics, and each focused on examining a key conceptual, methodological and/or theoretical issue associated with sociotechnical systems and safety. In this concluding paper, we describe the major conference themes and recommendations. These are organised into six topic areas: (1) Concepts, definitions and frameworks, (2) defining research methodologies, (3) modelling and simulation, (4) communications and decision-making, (5) sociotechnical attributes of safe and unsafe systems and (6) potential future research directions for sociotechnical systems research. Sociotechnical complexity, a characteristic of many contemporary work environments, presents potential safety risks that traditional approaches to workplace safety may not adequately address. In this paper, we summarise the investigations of a group of international researchers into questions associated with the application of sociotechnical systems thinking to improve worker safety.

Why Lean doesn't work for everyone.

Kaplan, Gary S; Patterson, Sarah H; Ching, Joan M; Blackmore, C Craig

2014-12-01

Popularisation of Lean in healthcare has led to emphasis on Lean quality improvement tools in isolation, with inconsistent results. We argue that delivery of safer, more efficient, and higher quality-patient focused care requires organisational transformation of which the Lean toolkit is only one component. To successfully facilitate system transformation toward higher quality care at lower cost, Lean tools must be part of a comprehensive management system, within a supportive institutional culture, and with committed leadership.

Designing clinically useful systems: examples from medicine and dentistry.

PubMed

Koch, S

2003-12-01

Despite promising results in medical informatics research and the development of a large number of different systems, few systems get beyond a prototype state and are really used in practice. Among other factors, the lack of explicit user focus is one main reason. The research projects presented in this paper follow a user-centered system development approach based on extensive work analyses in interdisciplinary working groups, taking into account human cognitive performance. Different medical and health-care specialists, together with researchers in human-computer interaction and medical informatics, specify future clinical work scenarios. Special focus is put on analysis and design of the information and communication flow and on exploration of intuitive visualization and interaction techniques for clinical information. Adequate choice of the technical access device is made depending on the user's work situation. It is the purpose of this paper to apply this method in two different research projects and thereby to show its potential for designing clinically useful systems that do support and not hamper clinical work. These research projects cover IT support for chairside work in dentistry (http://www.dis.uu.se/mdi/research/projects/orquest) and ICT support for home health care of elderly citizens (http://www.medsci.uu.se/mie/project/closecare).

Proposal of Network-Based Multilingual Space Dictionary Database System

NASA Astrophysics Data System (ADS)

Yoshimitsu, T.; Hashimoto, T.; Ninomiya, K.

2002-01-01

The International Academy of Astronautics (IAA) is now constructing a multilingual dictionary database system of space-friendly terms. The database consists of a lexicon and dictionaries of multiple languages. The lexicon is a table which relates corresponding terminology in different languages. Each language has a dictionary which contains terms and their definitions. The database assumes the use on the internet. Updating and searching the terms and definitions are conducted via the network. Maintaining the database is conducted by the international cooperation. A new word arises day by day, thus to easily input new words and their definitions to the database is required for the longstanding success of the system. The main key of the database is an English term which is approved at the table held once or twice with the working group members. Each language has at lease one working group member who is responsible of assigning the corresponding term and the definition of the term of his/her native language. Inputting and updating terms and their definitions can be conducted via the internet from the office of each member which may be located at his/her native country. The system is constructed by freely distributed database server program working on the Linux operating system, which will be installed at the head office of IAA. Once it is installed, it will be open to all IAA members who can search the terms via the internet. Currently the authors are constructing the prototype system which is described in this paper.

2016-10-01

The Asteroid Impact & Deflection Assessment (AIDA) mission is a joint ESA-NASA mission concept currently under study. AIDA has two components: the Double Asteroid Redirect Test (DART) is the US component designed to demonstrate a kinetic impactor, while the Asteroid Impact Mission (AIM) spacecraft is on station to do a thorough pre- and post-impact survey of the Didymos system.Members of the DART and AIM Investigation teams have been organized into several joint and independent working groups. While there is overlap in subject matter and membership between the groups, we focus here on the activities of the Observing Working Group.The first work by the group was undertaken during the spring of 2015, before DART entered Phase A. During this period Didymos made an apparition reaching roughly V ~ 20.5 in brightness, and our top priority was constraining which of two very different pole positions for the Didymos system was correct. Several telescopes in the 2-4-m aperture range around the world attempted observations. An observed mutual event allowed the one pole position to be ruled out. Didymos is now thought to be a low-obliquity, retrograde rotator, similar to many other asteroid binary systems and consistent with expectations from a YORP-driven origin for the satellite.We have begun planning for the 2017 apparition, occurring in the first half of the year. Didymos will be ~20% brighter at opposition than the 2015 apparition. Scaling from the successful observations with the 4.3-m Lowell Discovery Channel Telescope indicates that we will need telescopes at least 4 m (or larger, for some of the tasks, or at times longer before or after the opposition) in primary diameter for the advanced characterization in 2017.Currently, we have four goals for this apparition: 1) confirming the preferred retrograde pole position; 2) gathering data to allow BYORP-driven changes in the mutual orbit to potentially be determined by later observations; 3) establishing whether or not the secondary is in synchronous rotation with the primary; and 4) constraining the inclination of the satellite orbit.

A Data Analysis Expert System For Large Established Distributed Databases

The purpose of this work is to analyze the applicability of artificial intelligence techniques for developing a user-friendly, parallel interface to large isolated, incompatible NASA databases for the purpose of assisting the management decision process. To carry out this work, a survey was conducted to establish the data access requirements of several key NASA user groups. In addition, current NASA database access methods were evaluated. The results of this work are presented in the form of a design for a natural language database interface system, called the Deductively Augmented NASA Management Decision Support System (DANMDS). This design is feasible principally because of recently announced commercial hardware and software product developments which allow cross-vendor compatibility. The goal of the DANMDS system is commensurate with the central dilemma confronting most large companies and institutions in America, the retrieval of information from large, established, incompatible database systems. The DANMDS system implementation would represent a significant first step toward this problem's resolution.

The high frequency of criminal behaviour and related legal problems associated with substance addiction generates a field of interaction between legal and healthcare systems. This study was developed as a multicentre project to investigate the opinions of professionals from legal and healthcare systems about policies on illegal drugs and their implementation in practice. A multiple choice questionnaire designed ad hoc was administered to a sample of 230 professionals from legal and healthcare fields working in the cities of Barcelona, Granada and Bilbao. The questionnaire included sociodemographic and work-related data, and assessed interviewees' information about the response to drug-related crime and opinion on drug policy issues. This article presents the results from Spain. The main results showed that both groups of professionals value alternative measures to imprisonment (AMI) as useful tools to prevent offenses related to drug use and claim a broader application of AMI. They also evaluated positively the regulations on cannabis use in effect. Though the attitude of healthcare professionals towards the application of AMI is more permissive, both groups favour restricting these sanctions in cases of recidivism. Both groups show mild satisfaction with the current addiction healthcare system and express dissatisfaction with actual drug policies in Spain.

Managing System of Systems Requirements with a Requirements Screening Group

Figuring out an effective and efficient way to manage not only your Requirement’s Baseline, but also the development of all your individual requirements during a Program’s/Project’s Conceptual and Development Life Cycle Stages can be both daunting and difficult. This is especially so when you are dealing with a complex and large System of Systems (SoS) Program with potentially thousands and thousands of Top Level Requirements as well as an equal number of lower level System, Subsystem and Configuration Item requirements that need to be managed. This task is made even more overwhelming when you have to add in integration withmore » multiple requirements’ development teams (e.g., Integrated Product Development Teams (IPTs)) and/or numerous System/Subsystem Design Teams. One solution for tackling this difficult activity on a recent large System of Systems Program was to develop and make use of a Requirements Screening Group (RSG). This group is essentially a Team made up of co-chairs from the various Stakeholders with an interest in the Program of record that are enabled and accountable for Requirements Development on the Program/Project. The RSG co-chairs, often with the help of individual support team, work together as a Program Board to monitor, make decisions on, and provide guidance on all Requirements Development activities during the Conceptual and Development Life Cycle Stages of a Program/Project. In addition, the RSG can establish and maintain the Requirements Baseline, monitor and enforce requirements traceability across the entire Program, and work with other elements of the Program/Project to ensure integration and coordination.« less

Consciousness-raising in a gender conflict group.

Joel, Daphna; Yarimi, Dana

2014-01-01

This article describes the main processes and themes in consciousness-raising gender conflict groups for undergraduate students who study in parallel a course on gender and psychology. The main theme of the course is that gender is a classification system that influences individuals, interactions between individuals, and social institutions. The aim of the groups is to provide students with a safe environment to discuss their thoughts and feelings following the encounter of these ideas. Group leading is based on a combination of principles derived from consciousness-raising groups from the 1970s and a model for working with groups in conflict.

Operating the EOSDIS at the land processes DAAC managing expectations, requirements, and performance across agencies, missions, instruments, systems, and user communities

NASA developed the Earth Observing System (EOS) during the 1990'S. At the Land Processes Distributed Active Archive Center (LP DAAC), located at the USGS EROS Data Center, the EOS Data and Information System (EOSDIS) is required to support heritage missions as well as Landsat 7, Terra, and Aqua. The original system concept of the early 1990'S changed as each community had its say - first the managers, then engineers, scientists, developers, operators, and then finally the general public. The systems at the LP DAAC - particularly the largest single system, the EOSDIS Core System (ECS) - are changing as experience accumulates, technology changes, and each user group gains influence. The LP DAAC has adapted as contingencies were planned for, requirements and therefore plans were modified, and expectations changed faster than requirements could hope to be satisfied. Although not responsible for Quality Assurance of the science data, the LP DAAC works to ensure the data are accessible and useable by influencing systems, capabilities, and data formats where possible, and providing tools and user support as necessary. While supporting multiple missions and instruments, the LP DAAC also works with and learns from multiple management and oversight groups as they review mission requirements, system capabilities, and the overall operation of the LP DAAC. Stakeholders, including the Land Science community, are consulted regularly to ensure that the LP DAAC remains cognizant and responsive to the evolving needs of the user community. Today, the systems do not look or function as originally planned, but they do work, and they allow customers to search and order of an impressive amount of diverse data.

Influence of the acute alcoholism on the phagocytic function of the mononuclear phagocytic system

PubMed Central

Sabino, KR; Petroianu, A; Alberti, LR

2011-01-01

Rationale:Alcoholics are more likely to have infections, mainly in the respiratory system. Alcohol seems to inhibit the immune system. Despite the extensive literature related to alcoholism, data related to the immune system are still not conclusive. Objective: The purpose of this study was to verify the influence of acute alcohol intake on colloid distribution in the organs of the mononuclear phagocyte system. Methods and Results: Thirteen male Swiss mice were divided into two groups: Group 1 (n = 5) – control, and Group 2 (n = 8) – animals that received 0.5 ml ethanol 50%, 30 minutes before the experiment. Colloidal sulphur labeled with ⁸⁸mTc was used to evaluate colloid distribution in the liver, spleen and lungs. Colloid clearance was assessed as well. A gamma camera was used to measure the radioactivity of these organs and of a blood clot. No difference was found in the presence of colloid in the organs of both groups. The liver showed the highest phagocytic intake, followed by the spleen and lungs (p = 0.021 for Group 1 and p = 0.003 for Group 2). A minimum amount of radiation remained in the blood of both groups. Discussion: According to the experiential conditions of this work, acute ingestion of alcohol did not interfere with the phagocytic function of the mononuclear phagocyte system in mice.

Autoimmune diseases are a complex set of diseases characterized by immune system activation and, although many progresses have been done in the last 15years, several unmet needs in the management of these patients may be still identified. Recently, a panel of international Experts, divided in different working groups according to their clinical and scientific expertise, were asked to identify, debate and formulate a list of key unmet needs within the field of rheumatology, serving as a roadmap for research as well as support for clinicians. After a systematic review of the literature, the results and the discussions from each working group were summarised in different statements. Due to the differences among the diseases and their heterogeneity, a large number of statements was produced and voted by the Experts to reach a consensus in a plenary session. At all the steps of this process, including the initial discussions by the steering committee, the identification of the unmet needs, the expansion of the working group and finally the development of statements, a large agreement was attained. This work confirmed that several unmet needs may be identified and despite the development of new therapeutic strategies as well as a better understanding of the effects of existing therapies, many open questions still remain in this field, suggesting a research agenda for the future and specific clinical suggestions which may allow physicians to better manage those clinical conditions still lacking of scientific clarity.

Earlier this year, the Energy Facility Contractors Group (EFCOG) was asked to assist in developing options related to acceleration deployment of new security-related technologies to assist meeting design base threat (DBT) needs while also addressing the requirements of 10 CFR 830. NNSA NA-70, one of the working group participants, designated this effort the Safety and Security Interface Technology Initiative (SSIT). Relationship to Workshop Theme. “Supporting Excellence in Operations Through Safety Analysis,” (workshop theme)more » includes security and safety personnel working together to ensure effective and efficient operations. One of the specific workshop elements listed in the call for papers is “Safeguards/Security Integration with Safety.” This paper speaks directly to this theme. Description of Work. The EFCOG Safety Analysis Working Group (SAWG) and the EFCOG Security Working Group formed a core team to develop an integrated process involving both safety basis and security needs allowing achievement of the DBT objectives while ensuring safety is appropriately considered. This effort garnered significant interest, starting with a two day breakout session of 30 experts at the 2006 Safety Basis Workshop. A core team was formed, and a series of meetings were held to develop that process, including safety and security professionals, both contractor and federal personnel. A pilot exercise held at Idaho National Laboratory (INL) in mid-July 2006 was conducted as a feasibility of concept review. Work Results. The SSIT efforts resulted in a topical report transmitted from EFCOG to DOE/NNSA in August 2006. Elements of the report included: Drivers and Endstate, Control Selections Alternative Analysis Process, Terminology Crosswalk, Safety Basis/Security Documentation Integration, Configuration Control, and development of a shared ‘tool box’ of information/successes. Specific Benefits. The expectation or end state resulting from the topical report and associated implementation plan includes: (1) A recommended process for handling the documentation of the security and safety disciplines, including an appropriate change control process and participation by all stakeholders. (2) A means to package security systems with sufficient information to help expedite the flow of that system through the process. In addition, a means to share successes among sites, to include information and safety basis to the extent such information is transportable. (3) Identification of key security systems and associated essential security elements being installed and an arrangement for the sites installing these systems to host an appropriate team to review a specific system and determine what information is exportable. (4) Identification of the security systems’ essential elements and appropriate controls required for testing of these essential elements in the facility. (5) The ability to help refine and improve an agreed to control set at the manufacture stage.« less

Background: Cobalt is one of the most important constituent present in ceramic industries. Glazers are the relevant workers when they are producing blue colored ceramic, causing occupational exposure to such metal. Through this study, urinary cobalt was determined in glazers in a ceramic industry when they were producing blue-colored ceramic glazes. Methods: In this case-control study, spot urine samples were collected from 49 glazers at the start and end of work shifts (totally 98 samples) in 2011. Control group were well matched for age, height, and weight. A solid phase extraction system was used for separation and preconcentration of samples followed by analysis by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). All participants filled out a self administered questionnaire comprises questions about duration of exposure, work shift, use of mask, skin dermatitis, kind of job, ventilation system, overtime work, age, weight, and height. The lung function tests were performed on each control and cobalt exposed subjects. Analysis of covariance (ANCOVA) was used to evaluate the obtained results. Results: Urinary levels of cobalt were significantly higher in the glazers compared to the control group. There were significant differences at urinary concentration of cobalt at the start and end of the work shift in glazers. Spirometric parameters were significantly lower in the glazers compared to the control group. Among the variables used in questionnaire the significant variables were dermatitis skin, mask, ventilation, and overtime work. Conclusion: This study verified existence of cobalt in the urine glazers, showing lower amount than the ACGIH standard. PMID:26056641

The research group was established in 1967 at Lund University and moved to Karolinska Institutet in 1980. Work began with epidemiological studies of all injuries in the local community in support of various experimental local interventions. An important element was the creation of 'surveillance systems' in healthcare. The work resulted in the establishment of a WHO Collaborating Centre and an international safety-building programme called 'Safe Communities'. In parallel, training at both master's and doctoral level and the building of a conference programme were embarked upon. The research group consists of three sections. Specific efforts are being made by some countries to address their own injury problems.

A Module for Adaptive Course Configuration and Assessment in Moodle

Personalization and Adaptation are among the main challenges in the field of e-learning, where currently just few Learning Management Systems, mostly experimental ones, support such features. In this work we present an architecture that allows Moodle to interact with the Lecomps system, an adaptive learning system developed earlier by our research group, that has been working in a stand-alone modality so far. In particular, the Lecomps responsibilities are circumscribed to the sole production of personalized learning objects sequences and to the management of the student model, leaving to Moodle all the rest of the activities for course delivery. The Lecomps system supports the "dynamic" adaptation of learning objects sequences, basing on the student model, i.e., learner's Cognitive State and Learning Style. Basically, this work integrates two main Lecomps tasks into Moodle, to be directly managed by it: Authentication and Quizzes.

Applied Information Systems Research Program Workshop

1991-01-01

The first Applied Information Systems Research Program (AISRP) Workshop provided the impetus for several groups involved in information systems to review current activities. The objectives of the workshop included: (1) to provide an open forum for interaction and discussion of information systems; (2) to promote understanding by initiating a dialogue with the intended benefactors of the program, the scientific user community, and discuss options for improving their support; (3) create an advocacy in having science users and investigators of the program meet together and establish the basis for direction and growth; and (4) support the future of the program by building collaborations and interaction to encourage an investigator working group approach for conducting the program.

Distributed Deliberative Recommender Systems

Case-Based Reasoning (CBR) is one of most successful applied AI technologies of recent years. Although many CBR systems reason locally on a previous experience base to solve new problems, in this paper we focus on distributed retrieval processes working on a network of collaborating CBR systems. In such systems, each node in a network of CBR agents collaborates, arguments and counterarguments its local results with other nodes to improve the performance of the system's global response. We describe D2ISCO: a framework to design and implement deliberative and collaborative CBR systems that is integrated as a part of jcolibritwo an established framework in the CBR community. We apply D2ISCO to one particular simplified type of CBR systems: recommender systems. We perform a first case study for a collaborative music recommender system and present the results of an experiment of the accuracy of the system results using a fuzzy version of the argumentation system AMAL and a network topology based on a social network. Besides individual recommendation we also discuss how D2ISCO can be used to improve recommendations to groups and we present a second case of study based on the movie recommendation domain with heterogeneous groups according to the group personality composition and a group topology based on a social network.
