Antibody titers were lower in volunteers 50 years of age and older. Vaccination history against other flaviviruses yellow fever or tick borne encephalitis did not significantly influence PRNT50 titers. A two-step log-linear decline model predicted protection against JE of approximately 14 years after the booster dose. Six years after a booster dose against JE, long-term protection could be demonstrated.
According to our results, further booster doses should be scheduled 10 years following the first booster dose. The Gulf of Mexico ecosystem, six years after the Macondo oil well blowout. The Gulf of Mexico ecosystem is a hotspot for biological diversity and supports a number of industries, from tourism to fishery production to oil and gas exploration, that serve as the economic backbone of Gulf coast states. The Gulf is a natural hydrocarbon basin, rich with stores of oil and gas that lie in reservoirs deep beneath the seafloor.
The natural seepage of hydrocarbons across the Gulf system is extensive and, thus, the system's biological components experience ephemeral, if not, frequent, hydrocarbon exposure. In contrast to natural seepage, which is diffuse and variable over space and time, the Macondo oil well blowout, represented an intense, focused hydrocarbon infusion to the Gulf's deepwaters. The Macondo blowout drove rapid shifts in microbial populations and activity, revealed unexpected phenomena, such as deepwater hydrocarbon plumes and marine "oil snow" sedimentation, and impacted the Gulf's pelagic and benthic ecosystems.
Understanding the distribution and fate of Macondo oil was limited to some degree by an insufficient ability to predict the physical movement of water in the Gulf. In other words, the available physical oceanographic models lacked critical components. In the past six years , much has been learned about the physical oceanography of the Gulf, providing transformative knowledge that will improve the ability to predict the movement of water and the hydrocarbons they carry in future blowout scenarios.
Similarly, much has been learned about the processing and fate of Macondo hydrocarbons. Here, we provide an overview of the distribution, fate and impacts of Macondo hydrocarbons and offer suggestions for future research to push the field of oil spill response research forward. Comparison of traditional six-year and new four-year dental curricula in South Korea. This study aimed to compare the dental curriculum of the traditional six-year system with that of the new four-year graduate-entry system in South Korea. There are 11 dental schools in South Korea: Eight offer the new four-year program and the other three offer the traditional six-year program.
Descriptive analyses were conducted using bibliographic data and local information along with statistical analyses such as chi-square tests. In the six-year programs, clinical dentistry subjects were taught almost equally in practical and didactic courses, while the basic science courses were taught more often as practical courses P six-year program.

Ovarian tissue cryopreservation OTC and its future auto-transplantation becomes an alternative for patients to prevent serious damage of ovarian function by oncology treatment. Patient is indicated to OTC in case of high risk of ovarian failure due to planned chemotherapy and impossibility to use other oncofertility techniques. Ovarian tissue harvesting is done by laparoscopy in short-term general anesthesia.
After tissue processing the samples are cryopreserved in programmable automatic freezer or by vitrification. The auto-transplantation of ovarian tissue is planned after the complete cure of patient's malignancy. Our workplace doesn't have own experience with tissue transplantation - until now cryopreserved tissue has not yet been utilized by the patients.
Clinical experience with this technique gained by our team during academic stay in abroad Israeli clinic is presented. During the years of the OTC was performed in 19 cancer patients before chemotherapy. Average age of women was 26 years. The length of systemic chemotherapy averaged 7. Time from fertility preservation counseling to chemotherapy was not exceeding one week 7. Ovarian tissue harvesting was conducted by laparoscopic surgery in all cases.
The length of surgery did not exceed 60 minutes and no surgical complications were observed. The case of ovarian tissue transplantation performed on abroad university settings is discussed. In the consensus of with. Volcanic ash particles have an impact on the Earth's radiation budget and pose a severe danger to air traffic. Therefore, the ability to detect and characterize volcanic ash layers on a global and altitude-dependent scale is essential. It is also very sensitive to cloud and aerosol particles. From calculations of volcanic ash and ice particle optical properties, such as extinction coefficients and single scattering albedos as well as simulated MIPAS radiance spectra, we derived two optimal micro windows at Our method applies two radiance thresholds to detect volcanic ash.
The first one is derived from a statistical analysis of six years of measured MIPAS radiances in the selected spectral windows. This statistical threshold accounts only for pure volcanic ash detections. The second threshold allows more volcanic ash detections, because it accounts also for mixtures of ice and volcanic ash particles within the instrument's field of view. With the new method major eruptions from e. Condition of live fire-scarred ponderosa pine trees six years after removing partial cross sections.
Our objective was to document the effect of fire-history sampling on the mortality of mature ponderosa pine trees in Oregon.

A field test program of six m ft test: Consequences and coping strategies six years after a subarachnoid hemorrhage — A qualitative study. There is a lack of knowledge regarding long-term consequences experienced. Purpose To explore experiences of the care and rehabilitation as well as the consequences and strategies used to cope with everyday life six years post SAH. Methods An explorative interview study with a qualitative design.
Individual interviews, with open ended questions, using an interview guide were performed with sixteen participants mean age 63, 8 men, 8 women six years post SAH. Data was analyzed according to a descriptive thematic analysis, and themes were discovered inductively. Results Two major themes from the analysis, both including four sub-themes, were identified; these themes were consequences of the SAH and coping strategies. Participants were grateful to have survived the SAH and most were satisfied with their acute medical care. If discharged directly from the neurosurgical unit participants can feel abandoned.
In contrast, participants who were referred to a rehabilitation clinic felt supported and informed. Cognitive problems, such as impaired memory and mental fatigue, were reported as still present six years post SAH. Coping strategies were; receiving support from family, society, employers, or technical equipment. At work, talking to colleagues and to taking breaks were common.
Participants described hiding their symptoms from employers and friends, as well as trying to continue doing tasks in the same manner as prior to the SAH. If this was not possible, some refrained from doing these tasks. They went through a mourning process, fear, and worries. Conclusions Participants reported several long-term consequences which impacted on their daily lives post SAH, and different coping strategies were used to cope with these problems. Participants reported lack of awareness regarding the consequences of SAH and stressed the importance of structured.
Social inequalities and dental caries in six-year -old children from the Netherlands. The purpose of our study was to investigate the association of different socioeconomic and sociodemographic factors with dental caries in six-year -old children. Furthermore, we applied a district based approach to explore the distribution of dental caries among districts of low and high socioeconomic position SEP.
In our cross-sectional study six-year -olds were included. This study was embedded in a prospective population-based birth cohort study in Rotterdam, the Netherlands, the Generation R Study. Parental education level, parental employment status, net household income, single parenting, and teenage pregnancy were considered as indicators for SEP. Dental caries was scored on intraoral photographs by using the decayed, missing, and filled teeth dmft index. Multinomial logistic regression analyses and binary logistic regression analyses were performed to study the association between SEP and caries, and between district and caries, respectively.
Only maternal education level remained significantly associated with mild caries after adjusting for all other SEP-indicators. Paternal educational level, parental employment status, and household income additionally served as independent indicators of SEP in children with severe caries. Furthermore, living in more disadvantaged districts was significantly associated with higher odds of dental caries.
Dental caries is more prevalent among six-year -old children with a low SEP, which is also visible at the district level. Maternal educational level is the most important indicator of SEP in the association with caries. Our results should raise concerns about the existing social inequalities in dental caries and should encourage development of dental caries prevention strategies.
New knowledge about the distribution of oral health inequalities between districts should be used to target the right audience. The First Thirty- six Years: A History of the Albuquerque District, Further assembly and tests of Fifteen dates of spring-time SPOT HRV data along with near-concurrent vertical aerial photographic and phenological data from spring through spring were analyzed to monitor annual changes in a hectare, southeastern floodplain marsh. The marsh underwent rapid changes during the six years from a swamp dominated by non-persistent, thermally tolerant macrophytes to persistent macrophyte and shrub-scrub communities as reactor discharges declined to Pen Branch.
Savannah River flooding was also important in the timing of the shift of these wetland communities. The prevalence of syphilis at childbirth in Ireland: Re-emerging syphilis outbreaks across Europe have led to increasing syphilis rates among women of child-bearing age. We, therefore, identified all forms of syphilis cases among women hospitalized for delivery in Ireland over a six-year period. Cases per annum ranged from 10 to 24 Rates of syphilis in this universally screened cohort were four times higher than the general Irish population. Future studies examining the incidence of congenital syphilis as well as patterns in follow-up treatment for the sero-positive mother and her infant are needed to better guide clinical intervention.
The purpose was to collect data on surface-laid mines, UXO, submunitions, IED's, and background with a variety of optical sensors, for further use in the project. Three terrain types were covered: The sensors used in the field trial included UV, VIS, and NIR sensors as well as thermal, multi-spectral, and hyper-spectral sensors, 3-D laser radar and polarization sensors. Some of the sensors were mounted on an aerial work platform, while others were placed on tripods on the ground.
This paper describes the field trial and the presents some initial results obtained from the subsequent analysis. Empirical trials of plant field guides. We designed 3 image-based field guides to tropical forest plant species in Ghana, Grenada, and Cameroon and tested them with local residents and 20 botanists in the United Kingdom. We compared users' identification accuracy with different image formats, including drawings, specimen photos, living plant photos, and paintings.
We compared users' accuracy with the guides to their accuracy with only their prior knowledge of the flora. We asked respondents to score each format for usability, beauty, and how much they would pay for it. Prior knowledge of plant names was generally low field guides and nonspecialists to identify plants, for example, in conservation applications. We recommend authors of plant field guides use the cheapest or easiest illustration format because image type had limited bearing on accuracy; match the type of illustration to the most likely use of the guide for slight improvements in accuracy; avoid black and white formats unless the audience is experienced at interpreting illustrations or keeping costs low is imperative; discourage false-positive identifications, which were common; and encourage users to ask an expert or use a herbarium for.
Payment systems and oral health in Swedish dental care: Observations over six years. The aim of this longitudinal study of patients in regular dental care was to compare the findings of manifest caries and fillings after a 6-year adherence to either of two optional payment models, the traditional fee-for service FFS model, or the new capitation model 'Dental Care for Health' DCH.
Data on manifest caries lesions, the number of fillings and a number of background variables were collected from both a register and a questionnaire completed by 6, regular dental patients who met the inclusion criteria. The influence of payment system adherence and background variables on the number of manifest caries lesions at study end was examined by the means of negative binomial regression analysis. The incidence rate ratio of manifest caries lesions after six years in FFS was 1. The number of fillings was higher in FFS than in DCH at study start and at study end, and was also described by a steeper slope.
At group level, this study showed a statistically significant difference between the caries situation after six years in DCH compared with FFS, when some important background factors, including pre-baseline caries, were kept constant in a regression model. Propolis has been used as a natural health product mainly due to the presence of polyphenols, flavonoids, phenolic aldehydes, amino acids, vitamins and others bioactive constituents. To this natural substance are attributed different biological and pharmacological properties which are influenced by its chemical composition and organoleptic properties.
The aim of this work was to evaluate the physicochemical properties and parameters of green propolis collected during a period of six years in the state of Minas Gerais, located at the southeastern region of Brazil. The methodology were in accordance with Brazilian legislation on the identity and quality standards of propolis. The evaluated parameters of hydroalcoholic from green propolis were total flavonoids, antioxidant activity - DPPH method, oxidation index, wax content, humidity and insoluble impurities. Propolis samples collected in different seasons during the years to presented mean values of total flavonoids 3.
Green propolis did not show abrupt seasonal changes during the six years of investigation, and may be considered as an adequate functional ingredient. The London field trial for hoarding disorder. This study field -tested the validity, reliability and perceived acceptability of the proposed diagnostic criteria for HD. Method Fifty unselected individuals with prominent hoarding behavior and 20 unselected, self-defined 'collectors' participated in thorough psychiatric assessments, involving home visits whenever possible.
A semi-structured interview based on the proposed diagnostic criteria for HD was administered and scored by two independent raters. The percentage of true positive HD cases sensitivity and true negative HD cases specificity was calculated, along with inter-rater reliability for the diagnosis and each criterion. Participants were asked about their perceptions of the acceptability, utility and stigma associated with the new diagnosis. The sensitivity, specificity and inter-rater reliability of the diagnosis, and of each individual criterion and the specifiers, were excellent.
The proposed HD criteria are valid, reliable and perceived as acceptable and useful by the sufferers.

Clinical trials of GMP products in the gene therapy field. Advances in gene therapy are increasingly leading to clinical assessment in many fields of medicine with diverse approaches. As the technology advances, it is increasingly important to ensure that clinical trials answer the questions that need to be asked.
In this chapter we review examples of published clinical trials , resources for accessing information about registered trials , the process of regulating trials , good clinical practice, and good manufacturing practice as well as summarising the approach taken by regulatory authorities in reviewing applications for the introduction of products for use in the clinic.
First generation leishmaniasis vaccines: First generation candidate vaccines against leishmaniasis, prepared using inactivated whole parasites as their main ingredient, were considered as promising because of their relative ease of production and low cost. These vaccines have been the subject of many investigations over several decades and are the only leishmaniasis vaccine candidates which have undergone phase 3 clinical trial evaluation. Although the studies demonstrated the safety of the vaccines and several studies showed reasonable immunogenicity and some indication of protection, an efficacious prophylactic vaccine is yet to be identified.
Despite this overall failure, these trials contributed significantly to increasing knowledge on human leishmaniasis immunology. To provide a collective view, this review discusses the methods and findings of field efficacy trials of first generation leishmaniasis vaccine clinical trials conducted in the Old and New Worlds. The biochar community is excellent at pointing to individual cases where biochar amendment has changed soil properties, with some studies showing significant improvements in crop yields, reduction in nutrient export, and remediation of pollutants.
However, many studies exist which do not show improvements, and in some cases, studies clearly show detrimental outcomes.
The next, crucial step in biochar science and engineering research will be to develop a process-based understanding of how biochar acts to improve soil properties. In particular, we need a better mechanistic understanding of how biochar sorbs and desorbs contaminants, how it interacts with soil water, and how it interacts with the soil microbial community. These mechanistic studies need to encompass processes that range from the nanometer to the kilometer scale.
At the nanometer scale, we need a predictive model of how biochar will sorb and desorb hydrocarbons, nutrients, and toxic metals. At the micrometer scale we need models that explain biochar's effects on soil water, especially the plant-available fraction of soil water. The micrometer scale is also where mechanistic information is neeed about microbial processes.
At the macroscale we need physical models to describe the landscape mobility of biochar, because biochar that washes away from fields can no longer provide crop benefits. To be most informative, biochar research should occur along a lab-greenhouse- field trial trajectory. Laboratory experiments should aim determine what mechanisms may act to control biochar-soil processes, and then greenhouse experiments can be used to test the significance of lab-derived mechanisms in short, highly replicated, controlled experiments. Once evidence of effect is determined from greenhouse experiments, field trials are merited.
Field trials are the gold standard needed prior to full deployment, but results from field trials cannot be extrapolated to other field sites without the mechanistic backup provided. The purpose of this study is for the emotional skills of six-year -old children attending nursery school according to some variables.

In this article, we report on the search for gamma-ray emission from 20 magnetars using six years of Fermi Large Area Telescope observations. No significant evidence for gamma-ray emission from any of the currently known magnetars is found.
We derived the most stringent upper limits to date on the 0. We searched gamma-ray pulsations for the four magnetars having reliable ephemerides over the observing period, but detected none. The seven LRO instruments use a variety of primarily remote sensing techniques to obtain a unique set of observations. These measurements provide new information regarding the physical properties of the lunar surface, the lunar environment, and the location of volatiles and other resources. Scientific interpretation of these observations improves our understanding of the geologic history of the Moon, its current state, and what its history can tell us about the evolution of the Solar System.
Scientific results from LRO observations overturned existing paradigms and deepened our appreciation of the complex nature of our nearest neighbor. This paper summarizes the capabilities, measurements, and some of the science and exploration results of the first six years of the LRO mission. We report on the search for gamma-ray emission from 20 magnetars using six years of Fermi Large Area Telescope observations.
The effects of grooming on a copper ablative coating: These ships may spend long periods of time pier-side, which makes them vulnerable to fouling. Hull grooming has been proposed as a means of maintaining the coatings in an operational condition. This study investigated the effect of grooming on a copper ablative coating exposed statically for six years. Grooming was performed weekly or monthly with controls left ungroomed.
The fouling community was visually assessed, dry film thickness measurements were taken to monitor coating loss, and the copper leaching rates were measured. It was found that weekly and monthly groomed surfaces reduced fouling, and the ungroomed surfaces became fully fouled.
Coating loss was similar for weekly, monthly and ungroomed surfaces. The results suggest that grooming is a viable method for maintaining copper ablative coatings in a fouling-free condition without adverse increases in the total copper output.
Six-year pilot study on nucleic acid testing for blood donations in China. High residual risk was found in current blood donations screening in China. Case report of narcolepsy in a six-year -old child initially misdiagnosed as atypical epilepsy. This report describes a case of first-onset narcolepsy in a six-year -old female that was misdiagnosed as atypical epilepsy and other diagnoses at eight different hospitals over a period of 10 months before the correct diagnosis was made.
The diagnosis of narcolepsy is more difficult in children because very few of them experience all four cardinal symptoms of narcolepsy - paroxysmal sleep, cataplexy, hypnagogic hallucination, and sleep paralysis - and they often have a more prolonged onset and diverse symptoms. To decrease the time lag between initial presentation and accurate diagnosis, we recommend that in all cases in which children report excessive sleep of unknown etiology - regardless of the associated symptoms - that sleep monitoring and sleep latency tests be conducted to rule out the possibility of narcolepsy.
The case highlights the wide variety of presentations of uncommon psychiatric conditions, particularly in children, and the need for clinicians to be aware of the atypical presentations of these conditions when collecting medical histories. We describe a case of a six-year -old girl who presents multiple dysmorphic features characteristic of Down's syndrome. She has a significant general developmental delay, with a score that correspond to 32 months of developmental age.
This delay is especially in language, with a very scant vocabulary. She communicates with some hand sign words or pointing, although her auditory responses in hearing test were normal. This double trisomy is a rare condition described in isolated cases in the literature and none of these refers to the developmental aspects of these children Balwan et al.

Regardless of the level of practice, ICTs will continue influencing the careers of social workers and the clients they serve.
ICTs have received some attention in the social work literature and curriculum, but we argue that this level of attention is not adequate given their ubiquity, growth and influence, specifically as it relates to upholding social work ethics. Significant attention is needed to help ensure social workers are responsive to the technological changes in the health care system, including the health care infrastructure and use of technology among clients. Social workers also need ICT competencies in order to effectively lead different types of social change initiatives or collaborate with professionals of other disciplines who are using ICTs as part of existing strategies.
This paper also identifies potential pitfalls and challenges with respect to the adoption of ICTs, with recommendations for advancing their use in practice, education, and research. SLC currently provides a processing and launch capability for small-scale rockets; this capability will be augmented with additional ATDC facilities to provide a comprehensive and integrated in situ environment. Examples of Spaceport Technologies that will be supported by ATDC infrastructure include densified cryogenic systems, intelligent automated umbilicals, integrated vehicle health management systems, next-generation safety systems, and advanced range systems.
The ATDC can be thought of as a prototype spaceport where industry, government, and academia, in partnership, can work together to improve safety of future space initiatives. The ATDC is being deployed in five separate phases. Initial ATDC development will be completed in From the experience gained by the management team of Spaceport Malaysia, a popular service that can be provided by a planned commercial spaceport in a country without existing space travel infrastructure are zero gravity flights. Zero gravity flights range from parabolic flights using aerobatic airplane to suborbital flights using rockets, and in the near future using suborbital rocketplanes.
Therefore, zero gravity flights can be operated from a certified runway or planned for operation at a future commercial spaceport. With such range of operation, zero gravity flights provide a natural link between a low cost operation of small airplane to exclusive high profile operation of suborbital rocketplane, and this attracts the attention of individuals and organizations that are planning for the establishment of a commercial spaceport.
This is the approach chosen by the planners and developers of Spaceport Malaysia. A significant factor in zero gravity flight is the zero gravity time, the period where the payload onboard the airplane or rocketplane will experience zero gravity. Based on the momentum of the airplane or rocketplane, the zero gravity time may vary from few seconds to few minutes and that determines the quality of the zero gravity flight. To achieve zero gravity, the airplane or rocketplane will fly with a steady velocity for a significant time as a gravity control flight, accelerate upwards with an angle producing hypergravity and perform parabolic flight with natural momentum producing zero gravity and followed by dive that will result in another hypergravity flight.
An F-5E fighter jet owned by Royal Malaysian Air Force is being planned to be converted into a zero gravity platform to be operated at and by Spaceport. The objective was to advance current state-of-practices of geophysical technologies for detecting underground mine voids. The presence of old mine works above, adjacent, or below an active mine presents major health and safety hazards to miners who have inadvertently cut into locations with such features.
In addition, the presence of abandoned mines or voids beneath roadways and highway structures may greatly impact the performance of the transportation infrastructure in terms of cost and public safety. Thus, there is a need to utilize geophysical imaging technologies to accurately locate old mine works. Several surface and borehole geophysical imaging methods and mapping techniques were employed at a known abandoned coal mine in eastern Illinois to investigate which method best map the location and extent of old works.
In addition, several exploration borings were drilled to confirm the presence of the imaged mine voids. The results indicated that the RVSP is the most viable method to accurately detect the subsurface voids with horizontal accuracy of two to five feet. This method was then applied at several other locations in Colorado with various topographic, geologic, and cultural settings for the same purpose. This paper presents the significant results obtained from the geophysical investigations in Illinois.

Making technological innovation work for sustainable development. This paper presents insights and action proposals to better harness technological innovation for sustainable development. We begin with three key insights from scholarship and practice. First, technological innovation processes do not follow a set sequence but rather emerge from complex adaptive systems involving many actors and institutions operating simultaneously from local to global scales.
Barriers arise at all stages of innovation, from the invention of a technology through its selection, production, adaptation, adoption, and retirement. Second, learning from past efforts to mobilize innovation for sustainable development can be greatly improved through structured cross-sectoral comparisons that recognize the socio-technical nature of innovation systems. Third, current institutions rules, norms, and incentives shaping technological innovation are often not aligned toward the goals of sustainable development because impoverished, marginalized, and unborn populations too often lack the economic and political power to shape innovation systems to meet their needs.
However, these institutions can be reformed, and many actors have the power to do so through research, advocacy, training, convening, policymaking, and financing. We conclude with three practice-oriented recommendations to further realize the potential of innovation for sustainable development: The technology needs for space power systems military, public, commercial were assessed for the period to in the area of power management and distribution, components, circuits, subsystems, controls and autonomy, modeling and simulation. There was general agreement that the military requirements for pulse power would be the dominant factor in the growth of power systems.
However, the growth of conventional power to the to kw range would be in the public sector, with low Earth orbit needs being the driver toward large kw systems. An overall philosophy for large power system development is also described. Human Factors and Ergonomics Society, Technology in Social Work Education: Given the growing prevalence of technology -based instruction, social work faculty need a clear understanding of the strengths and limitations of these methods.

Technological innovations in factories and offices are examined in terms of 10 core issues: Information flow and work productivity through integrated information technology. The work environment surrounding integrated office systems is reviewed. The known effects of automated office technologies is synthesized and their known impact on work efficiency is reviewed.
Particular emphasis is given to structural changes due to the introduction of newer information technologies in organizations. The new information technologies have restructed the average organization's middle banks and, as a consequence, they have shrunk drastically. Organizational pyramids have flattened with fewer levels since executives have realized that they can get ahold of the needed information via the new technologies quicker and directly and do not have to rely on middle-level managers.
Power shifts are typically accompanied with the introduction of these technologies resulting in the generation of a new form of organizational power. Media received an update on the transition of government facilities to the aerospace industry, and how that approach enables NASA and industry success.

Pilot Project Technology Business Case: Performance advantages of the new pilot project technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities.
It is critical to demonstrate cost reductions or impacts on non-cost performance objectives in order for the business case to justify investment by nuclear operators. The cost and analysis side is not particularly difficult for the organization and can usually be determined with a fair amount of precision not withstanding implementation project cost overruns. The methodology is presented in the context of the entire process, but the tool provided is limited to determining the organizational benefits only.
This report describes a the use of the BCM in building a business case for mobile work packages, which includes computer-based procedures and other automated elements of a work package. Automated entry technologies for confined space work activities: Work in confined spaces poses a significant risk to workers and rescuers involved in the emergency response when an accident occurs. Despite several standards and regulations define the safety requirements for such activities, injuries, and fatalities still occur.
Furthermore, the on-site inspections after accidents often reveal that both employers and employees fail to implement safe entry procedures. Removing the risk is possible by avoiding the worker entry, but many activities require the presence of the operator inside the confined space to perform manual tasks. The following study investigates the available technologies for hazardous confined space work activities, e. The aim is to provide a systematic review of the automated solutions for high-risk activities in confined spaces, considering the non-man entry as the most effective confined space safety strategy.
Second, this survey aims to provide suggestions for future research addressing the design of new technologies. The survey consists of about 60 papers concerning innovative technologies for confined space work activities.

Knowledge management, health information technology and nurses' work engagement. Knowledge management KM extends the health information technology HIT literature by addressing its impact on creating knowledge by sharing and using the knowledge of health care professionals in hospitals. The aim of the study was to provide insight into how HIT affects nurses' explicit and tacit knowledge of their ongoing work processes and work engagement.
Data were collected from 74 nurses in four wards of a Dutch hospital via a paper-and-pencil survey using validated measurement instruments. In a quasiexperimental research design, HIT was introduced in the two experimental wards in contrast to the two control wards. At the time of the HIT introduction, a pretest was administered in all four wards and was followed by a posttest after 3 months. Data were analyzed via partial least squares modeling.
Generally, nurses' tacit knowledge i. In contrast, nurses' explicit knowledge i. Its effect on work engagement therefore depends on the mediating role of tacit knowledge. Interestingly, introducing HIT significantly affects only nurses' explicit knowledge, not their tacit knowledge or work engagement. Tacit knowledge insight into work processes appears to be pivotal, whereas efforts aimed only at improving available information will not lead to a higher level of work engagement in nurses' work environments.
Los Alamos scientists have advanced a Magnetic Resonance Imaging MRI technology that may provide a breakthrough for screening liquids at airport security. They've added low-power X-ray data to the mix, and as a result have unlocked a new detection technology. The goal is to quickly and accurately distinguish between liquids that visually appear identical. For example, what appears to be a bottle of white wine could potentially be nitromethane, a liquid that could be used to make an explosive.
Both are clear liquids, one would be perfectly safe on a commercial aircraft, the other would be strictly prohibited. How to tell them apart quickly without error at an airport security area is the focus of Michelle Espy, Larry Schultz and their team. In this video, Espy and the MagRay team explain how the new technology works , how they've developed an easy operator interface, and what the next steps might be in transitioning this technology to the private sector.
Examining Educational Climate Change Technology: This study with 79 students in Montreal, Quebec, compared the educational use of a National Aeronautics and Space Administration NASA global climate model GCM to climate education technologies developed for classroom use that included simpler interfaces and processes.
The goal was to show how differing climate education technologies succeed and fail at getting students to evolve in their understanding of anthropogenic global climate change AGCC. Many available climate education technologies aim to convey key AGCC concepts or Earth systems processes; the educational GCM used here aims to teach students the methods and processes of global climate modeling. We hypothesized that challenges to learning about AGCC make authentic technology -enabled inquiry important in developing accurate understandings of not just the issue but how scientists research it.
The goal was to determine if student learning trajectories differed between the comparison and treatment groups based on whether each climate education technology allowed authentic scientific research. Students who worked with a GCM demonstrated learning trajectories with larger gains, higher levels of engagement, and a better idea of how climate scientists conduct research. Students who worked with simpler climate education technologies scored lower in the course because of lower levels of engagement with inquiry processes that were perceived to not actually resemble the work of climate scientists.
