Full text: The purpose is to present the activities of Department of Radiation technologists at Medical College Sofia in knowledge management (KM) in human health applications and namely: continuous development of academic curriculum (AC) for medical radiation technologists (MRT) in sense of the conference motto “Nuclear Knowledge Management: Challenges and Approaches”. Our challenge is to realize, in practice, the important role of MRT professionals in healthcare. They are the front line in the patient safety and the last person with the patient before exposure. The existing AC has been periodically peer-reviewed: in 2011, 2014, and ongoing reviews, with the aim to guarantee that we are providing knowledge, skills and competencies that meet modern requirements for the training of radiation technologists. The AC compromises both academic and clinical education. The clinical component occurs throughout the academic course, accenting the role of MRT in radiology, radiotherapy and nuclear medicine. The approach of continuously developing the AC will meet the stringent requirements recently published by IAEA, with the goal that radiological medical practitioners, medical physicists, medical radiation technologists and other health professionals with specific duties in relation to protection and safety for patients in a given radiological procedure are specialized in the appropriate area.

The elastic and adhesive properties of nominally vertically aligned carbon nanotube (CNT) turfs have been measured using nanoindentation. The perceived stiffness of a CNT turf is dependent on the unloading rate, which decreases at slower unloading rates. Depth-controlled nanoindentation was used to examine adhesion effects. Adhesive loads between the turf and the probe tip increased as the time the tip is in contact with the turf increased. As these effects could be from either more tubes coming into contact with the tip due to relaxation and motion of CNTs relative to one another or each tube in contact increasing its adhesive behavior and sub-contact stiffness due to tube-tube interactions within the turf, electrical resistance measurements during nanoindentation were carried out. When the tip is held at a fixed nominal depth, the current remains constant while the contact load decreases, suggesting the number of tubes in contact with the tip stays constant with time while the relaxation mechanisms in the turf occur at positions lower than the contact surface. These observations, in conjunction with in situ TEM compression test of CNT arrays, are used to describe the relative effects the various length and time scales may have on the perceived properties measured during experiments, including elastic modulus and adhesion for gecko-like dry adhesives.

From Star Wars to 'turf wars'.

Science.gov (United States)

1999-09-01

Just as we are witnessing the re-emergence of Star Wars, it seems the 'turf wars' that have dogged A&E care are back. Since its inception as a specialty, A&E nurses have been accused of being 'Jacks (and Jill's, to be politically correct) of all trades and masters of none'. The inference being that all we do is 'mind' patients until they receive definitive care. Clearly this is not the case. As A&E nurses have demonstrated over the years, our skills are in the recognition and management of acute illness or injury, regardless of the patient's age, physical or psychological condition. Rather than being a 'master of none' we are masters of immediate care.

Recently, the importance of medical information for radiologic technologists has increased. The purpose of this questionnaire survey was to clarify the method of acquiring skill in medical information for radiologic technologists from the point of view of the managers of radiology departments. The questionnaire was sent to 260 hospitals that had introduced picture archiving and communication systems (PACSs) for the person responsible for medical information in the radiology department. The response rate was 35.4% (92 hospitals). The results of this survey clarified that few hospital have staff for medical information in the radiology department. Nevertheless, the excellent staff who have the skills to troubleshoot and develop systems are earnestly needed in radiology departments. To solve this problem, many technologists should understand the content, work load, and necessity of medical information. In addition, cooperation between radiologic technologist schools and hospitals is important in the field of medical information education. (author)

Role of the technologist

Bray, A.P.

1985-01-01

This paper discusses the role of the technologist in helping achieve all the objectives of the nuclear project - not only the technical objectives, but the business and societal objectives as well. It is important to realize at the outset the many objectives that the project can fulfill, including the contribution it can make to national development. The technologist may act as consultant, a partner, a business administrator or an agent of the utility, helping implement a management approach that furthers not only technical, but business and societal objectives as well. Two very different approaches to contracting are possible. On the one hand, the utility places heavy pressure on bidders to accept the risk of schedule and license, and forces suppliers to charge higher prices and make little use of local talent. On the other hand, the utility may recognize the need to develop national capability in the nuclear industry, and accept cooperative contracts which encourage suppliers to foster and employ local talent. This issue must be given attention in the initiation of future national nuclear power programs: whether to minimize the cost of the plant or maximize the cultivation and development of national capability

The relationship between turf toe and plantar foot pressures has not been extensively studied. Two hypotheses were tested in a cohort of professional American football players: first, that a history of turf toe is associated with increased peak hallucal and first metatarsophalangeal (MTP) plantar pressures; second, that decreased range of motion (ROM) of the first MTP correlates with increased peak hallucal and first MTP plantar pressures. Forty-four athletes from one National Football League (NFL) team were screened for a history of turf toe during preseason training. Dorsal passive MTP ROM and dynamic plantar pressures were measured in both feet of each player. Anatomical masking was used to assess peak pressure at the first MTP and hallux. First MTP dorsiflexion was significantly lower in halluces with a history of turf toe (40.6 +/- 15.1 degrees versus 48.4 +/- 12.8 degrees, p = 0.04). Peak hallucal pressures were higher in athletes with turf toe (535 +/- 288 kPa versus 414 +/- 202 kPa, p = 0.05) even after normalizing for athlete body mass index (p = 0.0003). Peak MTP pressure was not significantly different between the two groups tested. First MTP dorsiflexion did not correlate with peak hallucal or first MTP pressures. This study showed that turf toe is associated with decreased MTP motion. In addition, increased peak hallucal pressures were found. Further study is warranted to determine whether these pressures correlate with the severity of symptoms or progression of turf toe to first MTP arthritis.

Highlights: • Solar and terrestrial radian energy regimes affect temperature response of sports turfs. • Adjacent natural and artificial turfs were monitored with replications on sunny days. • Artificial turf has meager albedo, low specific heat and moisture to augment warming. • Artificial turf surface and substrate reach 70 °C but cool down effectively at night. • Artificial turf may induce heat stress on athletes in hot summer afternoon. - Abstract: Artificial turf can develop unusually high surface temperature on hot sunny days. Solar and terrestrial radiant energy regimes as key determinants of thermal performance deserve detailed investigation. This study evaluated six components of the radiant-energy environment of a natural turf (NT) and a contiguous artificial turf (AT) sports fields in Hong Kong: direct solar, reflected solar, net solar, sky thermal, ground thermal, and net thermal. Temperature was monitored at five positions: air at 150 cm, 50 cm and 15 cm height, turf surface, and substrate. The experiment included four replications, namely two summer sunny days, and two duplicated instrument sets at each turf site. The two sites reacted very differently to the same intense daily sum of solar radiation input of 23.70 MW m −2 with 9 h of bright sunshine (>120 W m −2 ), and daily sum of sky thermal radiation input of 38.59 MW m −2 . The maximum direct solar radiation reached 976.1 W m −2 at 1245 h. NT albedo of 0.23 vis-à-vis AT of merely 0.073, and higher moisture content and specific heat of NT materials, presented critical differences. The hydrophobic and generally dry plastic (polyethylene) pile-fibers and black rubber-granule infill materials have low specific heat. Intense incoming shortwave and longwave radiation absorbed readily by AT materials raised turf surface temperature to 70.2 °C and substrate 69.3 °C, in comparison with <40 °C at NT. A cascading warming effect was triggered, beginning with low albedo, high net solar

About the situation of nuclear medicine technologists in Japan, survey was made in August, 1979, by sending questionnaire to 219 facilities, and 341 technologists responded, the recovery rate being 70%. About the situation in the United States, the data were taken from the similar survey results in 1975 and 1976. The results in Japan, as compared with those in the United States, are described as follows: years of experience, contents of work, participation in society meetings and others, and occupation prior to the employment as nuclear medicine technologists. The findings are interesting in such items as the sexes of the technologists, the participation in meetings, and the types of works. In Japan, the technologists are dominantly male, while in the United States, more than 80% are female. In Japan, 97% of the technologists participated in society meetings and others. (J.P.N.)

A Mechanism of Land Degradation in Turf-Mantled Slopes of the Tibetan Plateau

Okin, Gregory S.; D'Odorico, Paolo; Liu, Jianquan

2018-05-01

Kobresia pygmaea meadows are typical of Tibetan Plateau landscapes in the 3,000 to 5,500 m elevation range and constitute the most extensive alpine ecosystem in the world. Kobresia pygmaea forms turf mats that stabilize the surface and shelter the underlying soils from water erosion. Large tracts of the Plateau, however, exhibit signs of ongoing degradation of the turf and erosion of the underlying soil. Despite the crucial role played by K. pygmaea turf mats in the stabilization of the headwaters of major Asian rivers, the mechanisms responsible for their degradation remain poorly investigated. Here we develop a process-based model of land degradation of Tibetan Plateau slopes, which accounts for (i) turf cracking, (ii) water flow concentration in the cracks, (iii) crack widening by scouring, and (iv) sheet-flow erosion. As expected, soil erosion increases with the slope and drainage area (hence the observation of stronger erosion in relatively steep downhill sites). Model simulations indicate that with a sensible set of parameters representative of soil and hydrologic conditions in the region, Tibetan Plateau landscapes are vulnerable to turf mat degradation and soil erosion. As soon as polygonal cracks develop, water flow widens them until the landscape is completely barren. At this point sheet flow eventually erodes the mineral soil leaving behind a highly degraded landscape.

Mann, April; Farrell, Mary Beth; Williams, Jessica; Basso, Danny

2017-06-01

In 2015, the Society of Nuclear Medicine and Molecular Imaging Technologist Section (SNMMI-TS) launched a multiyear quality initiative to help prepare the technologist workforce for an evidence-based health-care delivery system that focuses on quality. To best implement the quality strategy, the SNMMI-TS first surveyed technologists to ascertain their perception of quality and current measurement of quality indicators. Methods: An internet survey was sent to 27,989 e-mail contacts. Questions related to demographic data, perceptions of quality, quality measurement, and opinions on the minimum level of education are discussed in this article. Results: A total of 4,007 (14.3%) responses were received. When asked to list 3 words or phrases that represent quality, there were a plethora of different responses. The top 3 responses were image quality, quality control, and technologist education or competency. Surveying patient satisfaction was the most common quality measure (80.9%), followed by evaluation of image quality (78.2%). Evaluation of image quality (90.3%) and equipment functionality (89.4%) were considered the most effective measures. Technologists' differentiation between quality, quality improvement, quality control, quality assurance, and quality assessment seemed ambiguous. Respondents were confident in their ability to assess and improve quality at their workplace (91.9%) and agreed their colleagues were committed to delivering quality work. Of note, 70.7% of respondents believed that quality is directly related to the technologist's level of education. Correspondingly, respondents felt there should be a minimum level of education (99.5%) and that certification or registry should be required (74.4%). Most respondents (59.6%) felt that a Bachelor's degree should be the minimum level of education, followed by an Associate's degree (40.4%). Conclusion: To best help nuclear medicine technologists provide quality care, the SNMMI-TS queried technologists to

A health survey of more than 143,000 radiologic technologists is described. The population was identified from the 1982 computerized files of the American Registry of Radiologic Technologists, which was established in 1926. Inactive members were traced to obtain current addresses or death notifications. More than 6000 technologists were reported to have died. For all registrants who were alive when located, a detailed 16-page questionnaire was sent, covering occupational histories, medical conditions, and other personal and lifestyle characteristics. Nonrespondents were contacted by telephone to complete an abbreviated questionnaire. More than 104,000 responses were obtained. Most technologists were female (76%), white (93%), and employed for an average of 12 years; 37% attended college, and approximately 50% never smoked cigarettes. Radiation exposure information was sought from employer records and commercial dosimetry companies. Technologists employed for the longest times had the highest estimated cumulative exposures, with approximately 9% with exposures greater than 5 cGy. There was a high correlation between cumulative occupational exposure and personal exposure to medical radiographs, related, in part, to the association of both factors with attained age. It is interesting that 10% of all technologists allowed others to practice taking radiographs on them during their training. Nearly 4% of the respondents reported having some type of cancer, mainly of the skin (1517), breast (665), and cervix (726). Prospective surveys will monitor cancer mortality rates through use of the National Death Index and cancer incidence through periodic mailings of questionnaires. This is the only occupational study of radiation employees who are primarily women and should provide new information on the possible risks associated with relatively low levels of exposure

A covering path generation algorithm is developed to generate a lengthwise pattern based on a polygon describing the outer boundary and obstacles (polygon holes) of a geographical area. The algorithm is applied to an autonomous lawn-care robot for application to large grass turfs, for example golf......-courses, which require structured and precise cutting patterns. The geographical polygon is recorded by manually driving the vehicle around the contour, resulting in a polygon given as geographical (latitude, longitude) coordinates of the vertices, which together with machine parameters are used to generate...... a suitable toolpath. The algorithm has been tested on a recorded polygon from a local park turf which is non-convex and has holes, illustrating the algorithm functionality and limitations wrt. optimality. In particular, the algorithm can generate a tool-path for any polygon orientation....

Transplantation of subalpine wood-pasture turfs along a natural climatic gradient reveals lower resistance of unwooded pastures to climate change compared to wooded ones.

Climate change could impact strongly on cold-adapted mountain ecosystems, but little is known about its interaction with traditional land-use practices. We used an altitudinal gradient to simulate a year-round warmer and drier climate for semi-natural subalpine grasslands across a landscape of contrasting land-use management. Turf mesocosms from three pasture-woodland land-use types-unwooded pasture, sparsely wooded pasture, and densely wooded pasture-spanning a gradient from high to low management intensity were transplanted downslope to test their resistance to two intensities of climate change. We found strong overall effects of intensive (+4 K) experimental climate change (i.e., warming and reduced precipitation) on plant community structure and function, while moderate (+2 K) climate change did not substantially affect the studied land-use types, thus indicating an ecosystem response threshold to moderate climate perturbation. The individual land-use types were affected differently under the +4 K scenario, with a 60% decrease in aboveground biomass (AGB) in unwooded pasture turfs, a 40% decrease in sparsely wooded pasture turfs, and none in densely wooded ones. Similarly, unwooded pasture turfs experienced a 30% loss of species, advanced (by 30 days) phenological development, and a mid-season senescence due to drought stress, while no such effects were recorded for the other land-use types. The observed contrasting effects of climate change across the pasture-woodland landscape have important implications for future decades. The reduced impact of climate change on wooded pastures as compared to unwooded ones should promote the sustainable land use of wooded pastures by maintaining low management intensity and a sparse forest canopy, which buffer the immediate impacts of climate change on herbaceous vegetation.

This study evaluated the shoe-surface interaction of 15 football shoes made by 3 manufacturers in both anterior translation and rotation using a specially designed pneumatic testing system. The shoes included traditional cleated football shoes, "court" shoes (basketball-style shoes), molded-cleat shoes, and turf shoes. Under an 11.35-kg (25-pound) axial load, all shoes were tested on synthetic turf under wet and dry conditions and on natural stadium grass. Test-retest reliability, as calculated using the Pearson Product-Moment Correlation test, was 0.85 for force of translation and 0.55 for the moment of rotation. The wet versus dry surface values on translation were significantly different for rotation about the tibial axis. Spatting, which is protective taping of the ankle and heel applied on the outside of the shoe, resulted in a reduction of forces generated in both translation and rotation. No overall difference between shoes on grass versus AstroTurf was noted. However, there were significant differences for cleated and turf shoes. Shoes tested in conditions for which they were not designed exhibited reproducible excessive or extreme minimal friction characteristics that may have safety implications. On the basis of this study, we urge shoe manufacturers to display suggested indications and playing surface conditions for which their shoes are recommended.

The first metatarsophalangeal (MTP) joint complex is a critical weight-bearing structure important to biomechanics. An acute dorsiflexion injury, named "turf toe," is common among American football and soccer players. "Sesamoiditis" is a name often given for pain arising from the hallux sesamoids in the absence of acute trauma, and may result from a variety of causes. The first MTP joint complex can also be affected by degenerative or inflammatory arthritis, infarct, and infection. This review article will cover the anatomy and biomechanics of the first MTP joint complex, its patterns of injury and pathology, imaging techniques, and management. Copyright © 2015 Elsevier Inc.

Tay, Sock Peng; Fleming, Paul; Hu, Xiao; Forrester, Steph

2017-08-01

The occurrence of skin friction related injuries is an issue for artificial turf sports pitches and remains a barrier to their acceptance. The purpose of this study was to evaluate the current industry standard Securisport® Sports Surface Tester that measures skin surface related frictional behaviour of artificial turf. Little research has been published about the device and its efficacy, despite its widespread use as a standard FIFA test instrument. To achieve a range of frictional behaviours, several "third generation" (3G) carpet and infill combinations were investigated; friction time profiles throughout the Securisport rotations were assessed in combination with independent measurements of skin roughness before and after friction testing via 3D surface scanning. The results indicated that carpets without infill had greatest friction (coefficients of friction 0.97-1.20) while those completely filled with sand or rubber had similar and lower values independent of carpet type (coefficient of friction (COF) ≈0.57). Surface roughness of a silicone skin (s-skin) decreased after friction testing, with the largest change on sand infilled surfaces, indicating an "abrasive" polishing effect. The combined data show that the s-skin is damaged in a surface-specific manner, thus the Securisport COF values appear to be a poor measure of the potential for skin abrasion. It is proposed that the change in s-skin roughness improves assessment of the potential for skin damage when players slide on artificial turf.

Turf algal epiphytes metabolically induce local pH increase, with implications for underlying coralline algae under ocean acidification

Short, J.A.; Pedersen, Ole; Kendrick, G.A.

2015-01-01

The presence of epiphytic turf algae may modify the effects of ocean acidification on coralline algal calcification rates by altering seawater chemistry within the diffusive boundary layer (DBL) above coralline algal crusts. We used microelectrodes to measure the effects of turf algal epiphytes...... on seawater pH and the partial pressure of oxygen (pO2) within the DBL at the surface of Hydrolithoideae coralline algal crusts under ambient (36 Pa) CO2 and an ocean acidification scenario with elevated CO2 (200 Pa). Turf algae significantly increased the mean diel amplitude of pH and pO2, and this effect...... was more pronounced under elevated CO2. We suggest that increases in seawater CO2 under ocean acidification conditions may drive an increase in the abundance of epiphytic turf algae, consequently modifying the chemistry within the DBL. Thus, the effect of epiphytic turf algae on microscale pH is striking...

Phylogenetic Evidence for the Existence of Novel Thermophilic Bacteria in Hot Spring Sulfur-Turf Microbial Mats in Japan

So-called sulfur-turf microbial mats, which are macroscopic white filaments or bundles consisting of large sausage-shaped bacteria and elemental sulfur particles, occur in sulfide-containing hot springs in Japan. However, no thermophiles from sulfur-turf mats have yet been isolated as cultivable strains. This study was undertaken to determine the phylogenetic positions of the sausage-shaped bacteria in sulfur-turf mats by direct cloning and sequencing of 16S rRNA genes amplified from the bulk DNAs of the mats. Common clones with 16S rDNA sequences with similarity levels of 94.8 to 99% were isolated from sulfur-turf mat samples from two geographically remote hot springs. Phylogenetic analysis showed that the phylotypes of the common clones formed a major cluster with members of the Aquifex-Hydrogenobacter complex, which represents the most deeply branching lineage of the domain bacteria. Furthermore, the bacteria of the sulfur-turf mat phylotypes formed a clade distinguishable from that of other members of the Aquifex-Hydrogenobacter complex at the order or subclass level. In situ hybridization with clone-specific probes for 16S rRNA revealed that the common phylotype of sulfur-turf mat bacteria is that of the predominant sausage-shaped bacteria. PMID:9572936

The role of learning technologists in supporting e-research

Susi Peacock

2009-12-01

Full Text Available This article explores how the role of learning technologists, a professional group that has emerged during the last 15 to 20 years, may be diversifying to include supporting e-research. It contributes to the current debate about the emerging profession and the roles it should play in contemporary higher education. Previous studies have shown that, typically, the profession's role has focussed almost exclusively on curriculum development; traditionally, learning technologists work with students and tutors to enhance the learning environment with technology. This article presents two case studies of PhD research that used a standard e-learning tool, the virtual learning environment (VLE, to conduct focus groups online. The case studies demonstrate the expert role of the learning technologist in supporting researchers to make informed decisions about whether and how to use e-learning tools to conduct qualitative e-research. The learning technologist advised on the potential advantages and limitations of using the VLE for research and fostered collaborative, working relationships with the researchers, acquiring extensive background knowledge about their projects. This required the learning technologist to draw upon her own experience with research into e-learning and on her professional experience gained from supporting curriculum developments. It is suggested that many learning technologists could extend their roles, transferring their knowledge to include supporting e-research. A more inclusive model of the learning technologist's role in academia could help address the potential polarisation of the profession into researchers and practitioners.

Incidence of malignant lymphoma in adolescents and young adults in the 58 counties of California with varying synthetic turf field density.

Bleyer, Archie; Keegan, Theresa

2018-04-01

Case reports of cancer among soccer players raised concerns that the crumb rubber infill in synthetic turf fields may cause malignant lymphoma. One prior epidemiologic study on the topic found no association. An ecologic evaluation of county-level incidence of lymphomas by race/ethnicity and socioeconomic status for the state of California with data obtained from the National Cancer Institute Surveillance, Epidemiology, and End Results Program. Synthetic turf field density by county was obtained from the Synthetic Turf Council. During 2000-2013, 7214 14- to 30-year-old Californians were diagnosed with malignant lymphoma. Annual lymphoma county incidence trends were not associated with the county-level synthetic turf field density. None of 20 sub-analyses by race/ethnicity, sex and county median household income indicated a correlation of lymphoma incidence with synthetic turf field density. In California, there was no evidence at the county-level that synthetic turf fields are associated with an increased incidence of lymphoma in adolescents and young adults. Our findings in the state with the greatest number of such fields and a large, diverse patient population are consistent with those of a prior study observing no association between individual-level exposures to turf fields and cancer incidence. Avoidance of synthetic turf fields for fear of increased cancer risk is not warranted. Copyright © 2018 Elsevier Ltd. All rights reserved.

Maxima, minima, temporal components, and a measure of vibration were extracted from the data. Acceleration and GRF variables were compared statistically among surfaces. The synthetic surface often had the lowest peak accelerations, mean vibration, and peak GRFs. Peak acceleration during hoof landing was significantly smaller for the synthetic surface (mean + or - SE, 28.5g + or - 2.9g) than for the turf surface (42.9g + or - 3.8g). Hoof vibrations during hoof landing for the synthetic surface were dirt and turf surfaces. Peak GRF for the synthetic surface (11.5 + or - 0.4 N/kg) was 83% and 71% of those for the dirt (13.8 + or - 0.3 N/kg) and turf surfaces (16.1 + or - 0.7 N/kg), respectively. The relatively low hoof accelerations, vibrations, and peak GRFs associated with the synthetic surface evaluated in the present study indicated that synthetic surfaces have potential for injury reduction in Thoroughbred racehorses. However, because of the unique material properties and different nature of individual dirt, synthetic, and turf racetrack surfaces, extending the results of this study to encompass all track surfaces should be done with caution.

Professional liability of the radon technologist

The radon technologist will want to protect himself from lawsuits by plaintiffs who believe they have suffered consequences of a false measurement or erroneous recommendation. The author may be sued for negligence or on the contract. A plaintiff is more likely to be successful in a suit for monetary losses associated with real estate transactions or remediation than in a suit for personal injury. To avoid liability, the radon technologist will want to keep aware of the state of the art; use standard protocols; carefully supervise employees; take all technical precaution; and get legal advice in contracting. The author should also adhere to applicable federal, state, or local regulations. Disclosing the limits of measurement procedures and emphasizing the importance of maintaining standardized environmental conditions in the building are important. Since it is extremely difficult for an individual to get adequate professional liability insurance at a reasonable price, radon technologists should cooperate, perhaps through their professional societies, to negotiate the best possible insurance policies

An estimated 32,000 golf courses worldwide (approximately 25,600 km2), provide ecosystem goods and services and support an industry contributing over $124 billion globally. Golf courses can impact positively on local biodiversity however their role in the global carbon cycle is not clearly understood. To explore this relationship, the balance between plant–soil system sequestration and greenhouse gas emissions from turf management on golf courses was modelled. Input data were derived from published studies of emissions from agriculture and turfgrass management. Two UK case studies of golf course type were used, a Links course (coastal, medium intensity management, within coastal dune grasses) and a Parkland course (inland, high intensity management, within woodland).Playing surfaces of both golf courses were marginal net sources of greenhouse gas emissions due to maintenance (Links −2.2 ± 0.4 Mg CO2e ha(−1) y(−1); Parkland − 2.0 ± 0.4 Mg CO2e ha(−1) y(−1)). A significant proportion of emissions were from the use of nitrogen fertiliser, especially on tees and greens such that 3% of the golf course area contributed 16% of total greenhouse gas emissions. The area of trees on a golf course was important in determining whole-course emission balance. On the Parkland course, emissions from maintenance were offset by sequestration from turfgrass, and trees which comprised 48% of total area, resulting in a net balance of −5.4 ± 0.9 Mg CO2e ha(−1) y(−1). On the Links course, the proportion of trees was much lower (2%) and sequestration from links grassland resulted in a net balance of −1.6 ± 0.3 Mg CO2e ha(−1) y(−1). Recommendations for golf course management and design include the reduction of nitrogen fertiliser, improved operational efficiency when mowing, the inclusion of appropriate tree-planting and the scaling of component areas to maximise golf course sequestration capacity. The findings are transferrable to the management and design of

To reduce maintenance costs, municipalities and schools are starting to replace natural grass fields with a new generation synthetic turf. Unlike Astro-Turf, which was first introduced in the 1960s, synthetic field turf provides more cushioning to athletes. Part of this cushioning comes from materials like crumb rubber infill, which is manufactured from recycled tires and may contain a variety of chemicals. The goal of this study was to evaluate potential exposures from playing on artificial turf fields and associated risks to trace metals, semi-volatile organic compounds (SVOCs), and polycyclic aromatic hydrocarbons (PAHs) by examining typical artificial turf fibers (n = 8), different types of infill (n = 8), and samples from actual fields (n = 7). Three artificial biofluids were prepared, which included: lung, sweat, and digestive fluids. Artificial biofluids were hypothesized to yield a more representative estimation of dose than the levels obtained from total extraction methods. PAHs were routinely below the limit of detection across all three biofluids, precluding completion of a meaningful risk assessment. No SVOCs were identified at quantifiable levels in any extracts based on a match of their mass spectrum to compounds that are regulated in soil. The metals were measurable but at concentrations for which human health risk was estimated to be low. The study demonstrated that for the products and fields we tested, exposure to infill and artificial turf was generally considered de minimus, with the possible exception of lead for some fields and materials. © 2013 Society for Risk Analysis.

This work performed within the European RESSAC Programme aims at providing efficient countermeasures to decontaminate agricultural soils. The evaluation of the admissible concentration of radionuclides in the soil is an important question in this topic. Two considerations may help to answer this question: the health aspect approaches with ICRP recommendations and the economical aspects which can widely interfere with the other. If the cleaning technique is inexpensive, it will be possible to enlarge its use beyond the low intervention levels. According to the frequently low migration rate of radionuclides in the soil profile after deposition on the soil surface, a method removing a thin layer of the soil surface entrapped by turfing plants will allow to limit the waste production. The method being tried in summer 1991 is inexpensive because it uses the power of the plants to convert sunlight energy into biomass. The method consist in sowing turfing plants able to develop a very dense root network entrapping the soil surface contaminated particles allowing their mechanical removal by means of existing machines: sod harvesters. This promising method, according to lab-experiments, can use the green techniques as well for hydro-seeding: a very fast tool for sowing by helicopter at the rate of 0,3 km sup 2 per day, as sod harvester able to remove a sod-soil layer thinner than 2 cm.

Full text: Nuclear medicine has contributed to notable benefits to the human health from the very beginning. The Radioisotopes techniques, as well as the ionizing radiation used, have evolved providing functional and anatomical information of the patient, through non-invasive methods. With reference to Radiological Protection, the justification of each one of these practices and its perfect execution is intimately related to the benefit provided to the patients. The National Atomic Energy Commission apart from favouring the scientific and technological development, considers indispensable to work thoroughly on the professional training of the prospective technologists. Our over twenty-year experience in organizing and delivering courses of Technologists in Nuclear Medicine, although based on a much simpler program, have allowed the Institute of Nuclear Studies of the Ezeiza Atomic Center to acquire the capacity of developing a program to train highly qualified Technologists in that field. This project represents a step forward of great importance to the graduates qualification, since they will have the endorsement of CNEA and of the Faculty of Medicine of the Maimonides University. These are the three outstanding characteristics agreed on: 1.- General Education, carried out by subjects closely related to the optimisation of the relation Technologist - Patient - Environment and represented by: Radiological Protection and Hospital Security, Psychology, Ethics and Professional Medical Ethics, Nursing, English, Hygiene and Hospital Security and Management of the Quality in Services of Health. 2.- Diagnostic Procedures: planned according to organs, apparatuses or systems which are horizontally crossed by the anatomy, physiology and physiopathology Preparation of the patient, indications, main counter indications, radiopharmaceuticals, mechanisms of incorporation, pathologies, clinical protocols, instrumentation, post radiopharmaceuticals administration imaging

Full Text Available Objectives: It is recommended that magnetic resonance (MR technologists should not work alone due to potential occupational health risks although lone working is legally acceptable. The objective of this study was to investigate the current situation of lone working MR technologists in Western Australia (WA and any issue against the regulations. Materials and Methods: A questionnaire regarding the issues of occupational health of lone working MR technologists was developed based on relevant literature and distributed to WA MR technologists. Descriptive (percentage of frequency, mean and standard deviation and inferential statistics (Fisher's exact, Chi2 and t tests, and analysis of variance were used to analyze the responses of the yes/no, multiple choice and 5 pt scale questions from the returned questionnaires. Results: The questionnaire response rate was 65.6% (59/90. It was found that about half of the MR technologists (45.8%, 27/59 experienced lone working. The private magnetic resonance imaging (MRI centers were more likely to arrange technologists to work alone (p < 0.05. The respondents expressed positive views on issues of adequacy of training and arrangement, confidence and comfort towards lone working except immediate assistance for emergency (mean: 3. Factors of existence of MRI safety officer (p < 0.05 and nature of lone working (p < 0.001-0.05 affected MR technologists' concerns. Conclusions: Lone working of MR technologists is common in WA especially in private centers. The training and arrangement provided seem to be adequate for meeting the legal requirements. However, several areas should be improved by the workplaces including enhancement on immediate emergency assistance and concern relief.

Radiologic technologists are one of the occupational groups exposed to the highest dose of radiation worldwide. In Korea, radiologic technologists occupy the largest group (about 33%) among medical radiation workers and they are exposed to the highest dose of occupational dose of radiation as well (1). Although work experience with diagnostic radiation procedure of U.S. radiologic technologists was reported roughly (2), few studies have been conducted for description of overall work practices and the change by calendar year and evaluation of related factors on occupational radiation dose. The aims of the study are to describe work practices and to assess risk factors for occupational radiation dose among radiologic technologists in Korea. This study showed the work practices and occupational radiation dose among representative sample of radiologic technologists in Korea. The annual effective dose among radiologic technologists in Korea remains higher compared with those of worldwide average and varied according to demographic factors, year began working, and duration of working

Phenological observations on shrubs to predict weed emergence in turf

Phenology is the study of periodic biological events. If we can find easily recognizable events in common plants that precede or coincide with weed emergences, these plants could be used as indicators. Weed seedlings are usually difficult to detect in turf, so the use of phenological indicators may provide an alternative approach to predict the time when a weed appears and consequently guide management decisions. A study was undertaken to determine whether the phenological phases of some plants could serve as reliable indicators of time of weed emergence in turf. The phenology of six shrubs (Crataegus monogyna Jacq., Forsythia viridissima Lindl., Sambucus nigra L., Syringa vulgaris L., Rosa multiflora Thunb., Ziziphus jujuba Miller) and a perennial herbaceous plant [Cynodon dactylon (L.) Pers.] was observed and the emergence dynamics of four annual weed species [Digitaria sanguinalis (L.) Scop., Eleusine indica (L.) Gaertner, Setaria glauca (L.) Beauv., Setaria viridis (L.) Beauv.] were studied from 1999 to 2004 in northern Italy. A correlation between certain events and weed emergence was verified. S. vulgaris and F. viridissima appear to be the best indicators: there is a quite close correspondence between the appearance of D. sanguinalis and lilac flowering and between the beginning of emergence of E. indica and the end of lilac flowering; emergences of S. glauca and S. viridis were predicted well in relation to the end of forsythia flowering. Base temperatures and starting dates required to calculate the heat unit sums to reach and complete the flowering phase of the indicators were calculated using two different methods and the resultant cumulative growing degree days were compared.

Worldwide losses of coral with accompanying phase shifts to algae have been attributed to human alterations of major ecological processes, especially top down (herbivory) and bottom up (nutrients) forces. While positive effects on macroalgae have received some attention, less is known about turf algae. Closely cropped turf algae (French Polynesia. While this study will continue for 2 years, data here are for 5 weeks. We chose 3 sites in Cooks Bay that likely varied in nutrients and 3 along the north shore, presumably higher in herbivory. At each site 10 recruitment tiles were deployed. Turf communities accumulated over five-weeks while benthic and herbivorous fish communities were quantified at each site. Herbivorous fish communities consisted of juveniles and adults from the families Acanthuridae and Scaridae with both adult and juvenile acanthurids, comprising > 50% of all herbivorous fish. Sites within the bay, however, contained at least 66.7% less fish than sites along the north shore. In contrast benthic surveys portrayed little difference between sites, with turf making up > 70% of total hard bottom cover. Similarly, there was little difference among sites in the recruitment and growth rate ( 0.2-0.3 mm/week) of turf on tiles. While turf recruitment and early development appeared to be unaffected by herbivory or nutrients over the short time, we predict that longer-term effects will occur as this community develops.

Radiation dose to technologists per nuclear medicine examination and estimation of annual dose.

Conventional diagnostic nuclear medicine applications have been continuously increasing in most nuclear medicine departments in Turkey, but to our knowledge no one has studied the doses to technologists who perform nuclear medicine procedures. Most nuclear medicine laboratories do not have separate control rooms for technologists, who are quite close to the patient during data acquisition. Technologists must therefore stay behind lead shields while performing their task if they are to reduce the radiation dose received. The aim of this study was to determine external radiation doses to technologists during nuclear medicine procedures with and without a lead shield. Another aim was to investigate the occupational annual external radiation doses to Turkish technologists. This study used a Geiger-Müller detector to measure dose rates to technologists at various distances from patients (0.25, 0.50, 1, and 2 m and behind a lead shield) and determined the average time spent by technologists at these distances. Deep-dose equivalents to technologists were obtained. The following conventional nuclear medicine procedures were considered: thyroid scintigraphy performed using (99m)Tc pertechnetate, whole-body bone scanning performed using (99m)Tc-methylene diphosphonate, myocardial perfusion scanning performed using (99m)Tc-methoxyisobutyl isonitrile, and (201)Tl (thallous chloride) and renal scanning performed using (99m)Tc-dimercaptosuccinic acid. The measured deep-dose equivalent to technologists per procedure was within the range of 0.13 ± 0.05 to 0.43 ± 0.17 μSv using a lead shield and 0.21 ± 0.07 to 1.01 ± 0.46 μSv without a lead shield. Also, the annual individual dose to a technologist performing only a particular scintigraphic procedure throughout a year was estimated. For a total of 95 clinical cases (71 patients), effective external radiation doses to technologists were found to be within the permissible levels. This study showed that a 2-mm lead shield

It is essential to predict the long-term supply and demand for the number of radiologic technologists as medical resources. However, it is difficult to predict the number of Japanese radiologic technologists due to complex and intertwining factors. Our purpose in this study was to predict the future number of radiologic technologists using the concept of system dynamics (SD), and to clarify the effects of relevant factors. In order to estimate the number of Japanese radiologic technologists, we constructed a flow diagram using the concept of SD. We simulated the number of radiologic technologists for the following 4 cases: maintaining the status quo, a change in the pass rate for the national examination, a change in the post-graduate employment rate, and a change in the rate of continuing education. The result for the predicted number of radiologic technologists was 50,509 in 20 years, which is 4,394 (9.5%) more than the present number, and 50,166 in 40 years, which is 4,051 (8.8%) more than the present number. For the factors influencing the number of technologists, the influence of the pass rate on the national examination and that of the rate for post-graduate employment was larger than that of the rate of continuing education in graduate school. The number of Japanese radiologic technologists will increase until 2033 and decrease until 2042, and it does not change after 2042 in case of maintaining the status quo. Implementing the concept of SD allowed us easily to clarify the factors influencing the predicted number of radiologic technologists.

A study on the civil liability of radiological technologist in medical malpractice

Recently the suits for medical malpractice are gradually increasing in this country. The main purpose of this study is to excavate the most suitable theories about civil liabilities on medical malpractice by radiological technologist. To solve the above-mentioned problems in medical malpractice, I have proceeded to make a survey of traditional theories and tried to excavate the most suitable theories for our medical circumstances among those theories. Both domestic and foreign relevant professional literatures and legal cases were investigated in this study. Several important findings of this study are as follows. First, the nature of legal interrelationship between radiological technologist and physician(or the representative of a hospital) is to define the content of employment. But in the eye of medical law, the interrelationship between radiological technologist and physician is written that radiological technologist should be directed by physician. Second, the nature of legal interrelationship between patient and physician(or the representative of a hospital) is to define the content of legal obligation of physician(or the representative of a hospital), and radiological technologist execute his obligation as proxy for physician. Therefore, patient can not clame any legal right to radiological technologist. Third, radiological technologist has the obligation of Due Care in medical practice. Fourth, on the medical malpractice by radiological technologist the civil liability can be treated as either tortious liability or contractual liability, and physician (or the representative of hospital) take the responsibility for the damage compensation. In this case, physician has the right of indemnity to radiological technologist. But it should be dinied or extremely limited

This paper analyzes differences and changes within and between the occupation of nurses, radiological technologists, and medical technologists concerning starting salary from April 2005 to March 2009. This paper also investigates the percentage of difference in the amount of starting salary of nurses, radiological technologists, and medical technologists according to their educational attainments. The research-target used was the full-time-job-opening data provided to Okayama University within the given period of time, which specifies the amount of starting salary. The result shows that one's educational background has a crucial influence on the amount of one's starting salary. In fact, the percentage of the amount of starting salary base on one's educational attainment all increased in nurses, radiological technologists, and medical technologists from April 2007 to March 2009. However, this percentage for radiological technologists remains only 50% of increase, which was less significant than other two professional occupations. Moreover, the result indicates a crucial change in the amount of basic starting salary: while the amount of basic starting salary of nurses in 2008 has increased since 2005, that of radiological technologists has dropped remarkably. If this situation is not improved in the near future, the health-service sector may experience a decrease in the number of skilled practitioners which, in turn, will result in a decline in quality of medical care.

Meyers, Michael C

2017-03-01

Numerous injuries have been attributed to playing on artificial turf. More recently, newer generations of artificial turf have been developed to duplicate the playing characteristics of natural grass. Although artificial turf has been deemed safer than natural grass in some studies, few long-term studies have been conducted comparing match-related collegiate soccer injuries between the 2 playing surfaces. Collegiate male soccer athletes do not experience any difference in the incidence, mechanisms, or severity of match-related injuries between FieldTurf and natural grass. Cohort study; Level of evidence, 2. Male soccer athletes from 11 universities were evaluated over 6 seasons. Demographic features and predictors included player position, cleat design, player weight, turf age, and environmental factors. Outcomes of interest included injury incidence, injury category, time loss, injury mechanism and situation, type of injury, injury grade and anatomic location, injury severity, head and lower extremity trauma, and elective medical procedures. All match-related injuries were evaluated by the attending head athletic trainer and team physicians on site and subsequently in the physician's office when further follow-up and treatment were deemed necessary. In sum, 765 collegiate games were evaluated for match-related soccer injuries sustained on FieldTurf or natural grass during 6 seasons. Overall, 380 team games (49.7%) were played on FieldTurf versus 385 team games (50.3%) played on natural grass. A total of 722 injuries were documented, with 268 (37.1%) occurring on FieldTurf and 454 (62.9%) on natural grass. Multivariate analysis per 10 team games indicated a significant playing surface effect: F 2,720 = 7.260, P = .001. A significantly lower total injury incidence rate (IIR) of 7.1 (95% CI, 6.6-7.5) versus 11.8 (95% CI, 11.3-12.2; P < .0001) and lower rate of substantial injuries, 0.7 (95% CI, 0.5-1.0) versus 1.9 (95% CI, 1.5-2.3; P < .03), were documented on FieldTurf

T-urf13, a well-documented cms-associated gene from maize, has been shown to render methomyl sensitivity to heterologous systems like rice, yeast and bacteria when expressed constitutively. Since these transgenic plants were fertile, it was hypothesized that T-urf13 gene if expressed in anthers may result in male sterility that could be used for hybrid seed production. Hence, this work was aimed at analysing whether T-urf13 gene when expressed in anthers can result in male sterile plants or r...

[Strategies to Cope with the Shortage of Technologists: Facing the Mass-Retirement of the 'Baby-Boomer' Generation].

Morikane, Keita; Yamada, Miyuki

In Japan, the primary 'baby-boomer' generation, born between 1947 and 1949, is now in its retirement. This has caused a marked shortage of human resources nationwide. Clinical laboratory technologists are no exception, and many clinical laboratories in Japanese healthcare facilities are struggling with management because the number of new graduates, i.e., newly licensed technologists, is mostly fixed and, therefore, their recruitment is becoming more and more competitive. Our laboratory is now facing a wave of mass-retirement associated with our history. In addition, in the early 2000s, there was almost no position for new graduates replacing those retiring because of the change in the social healthcare system as well as our hospital's policy. This resulted in uneven numbers of technologists in generations, and it seemed to be getting worse. Fortunately, five years ago, the direction of social health care was changed and lots of positions became available as a result. We have been trying to recruit new graduates and experienced technologists as well, and were able to hire 18 people. Among them, 8 were non-freshmen. The generation gap has been mostly resolved. We will continue to make our laboratory more attractive not just to new graduates but also to experienced technologists, especially those who wish to return to work after a several-year absence to raise their children. We believe that this will energize our laboratory.

Johnson, Maggie D.; Comeau, Steeve; Lantz, Coulson A.; Smith, Jennifer E.

Turf algal assemblages are ubiquitous primary producers on coral reefs, but little is known about the response of this diverse group to ocean acidification (OA) across different temperatures. We tested the hypothesis that CO2 influences the functional response of epilithic and endolithic turf assemblages to increasing temperature. Replicate carbonate plugs covered by turf were collected from the reef and exposed to ambient and high pCO2 (1000 µatm) conditions for 3 weeks. Each pCO2 treatment was replicated across six temperatures (24.0-31.5 °C) that spanned the full seasonal temperature range on a fringing reef in Moorea, French Polynesia, and included one warming treatment (3 °C above daily average temperatures). Temperature and CO2 enrichment had complex, and sometimes interactive, effects on turf metabolism and growth. Photosynthetic and respiration rates were enhanced by increasing temperature, with an interactive effect of CO2 enrichment. Photosynthetic rates were amplified by high CO2 in the warmest temperatures, while the increase in respiration rates with temperature were enhanced under ambient CO2. Epilithic turf growth rates were not affected by temperature, but increased in response to CO2 enrichment. We found that CO2 and temperature interactively affected the endolithic assemblage, with the highest growth rates under CO2 enrichment, but only at the warmest temperatures. These results demonstrate how OA may influence algal physiology and growth across a range of ecologically relevant temperatures, and indicate that the effects of CO2 enrichment on coral-reef turf assemblages can be temperature dependent. The complex effects of CO2 enrichment and temperature across a suite of algal responses illustrates the importance of incorporating multiple stressors into global change experiments.

Radiological assessment of the use of turf cut from sea-washed land

International Nuclear Information System (INIS)

2000-01-01

For more than 40 years, sea-washed land along the coast of north Wales, northwest England and southwest Scotland has received sediment containing artificial radionuclides as a result of authorised discharges into the Irish Sea from the Sellafield nuclear fuel reprocessing plant. Some parts of this sea-washed land have been used to produce high-quality turf for many years, and the radiation doses to those people who abstract the turf have been kept under review by Government departments and agencies. For the turf-cutters themselves, external irradiation was the dominant exposure pathway. The original intention was to estimate external dose rates arising from non-natural sources by taking field dose rate measurements and subtracting an appropriate background dose rate measured at a control site that contained, as far as possible, only naturally occurring radionuclides. This approach is similar to that adopted in the previous study undertaken by the Fisheries Research Laboratory (now CEFAS) in 1989. However, in some cases subsequent radiochemical analyses indicated that the control sites had been inundated by the sea. Consequently, external dose rates attributable to non-natural sources were estimated using measurements of concentrations of artificial radionuclides at various depths in the soil, together with an established predictive model. Observed and predicted external dose rates were compared for those sites where the controls were suitable. The predicted values were up to about five times greater than those observed in the field. This was to be expected because the predictions were based on small locations where concentrations of radionuclides in soil were highest, whereas instrument measurements at the same location would give values that were representative of an area of about 20 m in diameter. At most sites, the overall annual doses to turf-cutting operatives were less than 10 (μSv. In some cases this was due to very low external dose rates and in others to

The aim of this study was to grasp the actual conditions of the radioprotective education in the educational facilities for radiological technologists, and to discuss the ideal way of radioprotective education toward the 21st century. For this purpose, we sent out the questionnaire concerning the circumstances of radioprotective education to 38 educational facilities for radiological technologists in Japan, including 6 universities, 15 junior colleges and 15 technical schools. This research was carried out on March, 1997, and the answers were obtained total 34 educational facilities (86.8%) (6 universities, 15 junior colleges and 13 technical schools) in total. Among the educational facilities in Japan, universities were much richer than the other two facilities in every respect on the educational circumstances including number and the quality of teaching staffs, educational institutions and equipment, practical training facilities and equipment, the number of collection of books in the library, etc. In the process of education for radiological technologists, the background to cause problems concerning the radioprotective education was largely dependent on the difference of educational schemes in Japan. From the view point of the elevation of educational standard for radiological technologists, it is better to transfer all educational processes to the universities, and give high and full level of radioprotective education in universities. And in the field of the medical radiology, the radioprotection and the management system should also be strengthened. For this purpose, it is also required to revise the related laws drastically, to strengthen lessons related to the radioprotection and to plan the richness in contents of the radioprotective education.

1986-05-01

Radiation exposures incurred by nuclear medicine technologists during diagnostic imaging and gamma camera quality control (QC) were measured on a procedural basis over a three-month period using a portable, low-range, self-reading ion chamber. A total of more than 400 measurements were made for 15 selected procedures. From these, mean procedural exposures and standard deviations were calculated. The results show that daily flood phantom QC, at 0.58 mR, and gated cardiac studies, at 0.45 mR, were the two greatest sources of exposure. Other procedures resulted in exposures varying roughly from 0.10 to 0.20 mR. Difficult patients were responsible for a doubling of technologist exposure for many procedures. Standard deviations were large for all procedures, averaging 65% of the mean values. Comparison of technologist exposure inferred from the procedural measurements with the time coincident collective dose equivalent recorded by the TLD service of the Radiation Protection Bureau indicates that approximately half of the collective technologist exposure arose from patient handling and flood QC

2018-01-01

Thousands of synthetic turf fields in the US are regularly used by millions of individuals (particularly children and adolescents). Although many safety assessments have concluded that there are low or negligible risks related to exposure to chemicals found in the recycled rubber used to make these fields, concerns remain about the safety of this product. Existing studies of recycled rubber's potential health risks have limitations such as small sample sizes and limited evaluation of relevant exposure pathways and scenarios. Conduct a comprehensive multipathway human health risk assessment (HHRA) of exposure to chemicals found in recycled rubber. All available North American data on the chemical composition of recycled rubber, as well as air sampling data collected on or near synthetic turf fields, were identified via a literature search. Ingestion, dermal contact, and inhalation pathways were evaluated according to US Environmental Protection Agency (US EPA) guidance, and exposure scenarios for adults, adolescents, and children were considered. Estimated non-cancer hazards and cancer risks for all the evaluated scenarios were within US EPA guidelines. In addition, cancer risk levels for users of synthetic turf field were comparable to or lower than those associated with natural soil fields. This HHRA's results add to the growing body of literature that suggests recycled rubber infill in synthetic turf poses negligible risks to human health. This comprehensive assessment provides data that allow stakeholders to make informed decisions about installing and using these fields. Copyright © 2017 Elsevier Inc. All rights reserved.

Recently, there have been marked advances in the technological strategies employed in medical examinations. The educational concept to nurture highly capable medical technologists is considered to be a priority issue by not only educators but also employers, even though the medical educational levels have markedly improved in every college and university. It is commonly acknowledged that the results of any examination in the clinical laboratory should be accurate and fed back to medical doctors as soon as possible. The business outline of medical technologists in our hospital is becoming more extensive because we act as a core hospital in the area, and so knowledge regarding many kinds of chemical and transfusion examinations is required in operations performed around the clock. Furthermore, medical doctors, clerical workers, nurses, and volunteers comprise a team of sophisticated workers in our hospital. To accomplish our daily work, character traits such as accuracy, honesty, perseverance, and ability to follow instruction manuals, are the most fundamental and valuable. To nurture a highly career-oriented medical technologist, we propose that the following should be focused on: self-responsibility, reduction of malpractices, economic profitability, brainstorming, education of subsequent generations, and the spirit of cooperativeness and reconciliation. Additionally, it is another basic requirement of competent medical technologists to learn to adapt to laboratory-based changes in their work throughout their career. In conclusion, how to adapt to any social demand and learn strategies in any era should be taught in college or university as well as after graduation because each hospital and institute has a different philosophy and requirements of newcomers. It is important for medical technologists and doctors to develop flexible ways of thinking, although we sometimes might accede to traditional ways.

The aim of this research was to evaluate the influence of the mechanical properties of artificial turf systems on soccer players’ performance. A battery of perceptive physiological and physical tests were developed on four different structural systems of artificial turf (System 1: Compacted gravel sub-base without elastic layer; System 2: Compacted gravel sub-base with elastic layer; System 3: Asphalt sub-base without elastic layer; System 4: Asphalt sub-base with elastic layer). The sample was composed of 18 soccer players (22.44±1.72 years) who typically train and compete on artificial turf. The artificial turf system with less rotational traction (S3) showed higher total time in the Repeated Sprint Ability test in comparison to the systems with intermediate values (49.46±1.75 s vs 47.55±1.82 s (S1) and 47.85±1.59 s (S2); pperformance in jumping tests (countermovement jump and squat jump) and ball kicking to goal decreased after the RSA test in all surfaces assessed (pperformance deterioration (p>0.05). The physiological load was similar in all four artificial turf systems. However, players felt more comfortable on the harder and more rigid system (S4; visual analogue scale = 70.83±14.28) than on the softer artificial turf system (S2; visual analogue scale = 54.24±19.63). The lineal regression analysis revealed a significant influence of the mechanical properties of the surface of 16.5%, 15.8% and 7.1% on the mean time of the sprint, the best sprint time and the maximum mean speed in the RSA test respectively. Results suggest a mechanical heterogeneity between the systems of artificial turf which generate differences in the physical performance and in the soccer players’ perceptions. PMID:25354188

Algal Turf Scrubbers: Cleaning Water while Capturing Solar Energy for Bio fuel Production

Jeffrey Bannon, J.; Adey, W.

2010-01-01

Algal Turfs are bio diverse communities of unicellular to filamentous algae of all major algal phyla. Algal Turf Scrubbers (ATS) are bioengineered ecosystems dominated by algal turfs. They clean water to very high quality, and remove CO 2 from the atmosphere by capturing solar energy at rates 10 times that of agriculture and 50 times that of forestry. Since they are controlled ecosystems, using local algae, ATS does not suffer the major disadvantages of agricultural crops, which for maximum efficiency require fertilizers, herbicides and pesticides. ATS removes CO 2 from water and the atmosphere, and can be configured to remove CO 2 from power plant stack gases. As a normal part of operations, ATS removes heavy metals, break down toxic hydrocarbons, and oxygenates treated waters. ATS systems are capable of removing nitrogen and phosphorous from surface waters in the mid latitude US at $0.60/kg and $10.60/kg respectively (10% of the cost certified by the Chesapeake Bay Commission), and independently producing an energy product at $0.85/gallon. Given a nutrient credit system for rewarding nutrient removal from rivers and lakes, this price can be driven down to below $.40/gallon. Conservatively ATS can produce the equivalent of US imported oil on less than 30 M acres of land along major rivers

Effect of light and nutrient availability on the release of dissolved organic carbon (DOC) by Caribbean turf algae.

Turf algae increasingly dominate benthic communities on coral reefs. Given their abundance and high dissolved organic carbon (DOC) release rates, turf algae are considered important contributors to the DOC pool on modern reefs. The release of photosynthetically fixed carbon as DOC generally, but not always, increases with increased light availability. Nutrient availability was proposed as an additional factor to explain these conflicting observations. To address this proposed but untested hypothesis, we documented the interactive contributions of light and nutrient availability on the release of DOC by turf algae. DOC release rates and oxygen production were quantified in incubation experiments at two light levels (full and reduced light) and two nutrient treatments (natural seawater and enriched seawater). In natural seawater, DOC release at full light was four times higher than at reduced light. When nutrients were added, DOC release rates at both light levels were similar to the natural seawater treatment at full light. Our results therefore show that low light in combination with low nutrient availability reduces the release of DOC by turf algae and that light and nutrient availability interactively determine DOC release rates by this important component of Caribbean reef communities.

Purpose: The purpose of this study was to present ideas to upgrade job performance and improve organizational management by analyzing leadership aspects and organizational cultures of radiological technologist organizations. Method: A questionnaire was used to collect data from 261 radiological technologists working in the city of Busan. Then, SPSS/PC + Win 13 was used to statistically analyze the collected data. One-way ANOVA was adopted to test differences among groups, and multiple regression analyses were conducted to examine the effect of organizational culture and leadership upon organizational effectiveness. Results: First, it was found that radiological technologists stressed consensus most among the 4 types of organizational culture and regarded core transformational leadership as the right type of leadership. Second, regarding the relationship between leadership and organizational effectiveness, transformational leadership had the highest influence upon organizational effectiveness. Third, as for the relationship between organizational culture and organizational effectiveness, it was found that a developmental culture has the highest influence upon organizational effectiveness, followed by a culture of consensus. Conclusion: If transformational leadership and consensual culture are used properly for upgrading job performance in the organization, conflicts among radiological technologists might be reduced, thereby enhancing organizational effectiveness.

The management of golf course is different from other turfs. Its particularity lies in its higher and more precise requirement during maintenance compare with other turfs. In case something happened to turf of golf course, more effective and higher speed detecting and resolution are required. Only the data about turf growth and environment were mastered precisely in time, the friendly environmental and scientific management goal could be completed effectively and economically. The near infrared spectroscopy is a new kind of effective, convenient and non-destructive analytical method in the turfgrass management of golf course in recent years. Many factors of turf-soil system in golf course could be determined by near infrared spectroscopy at the same time. In this paper, the existing literature that use of near infrared spectroscopy to study turfgrass and soil nutrient content, soil hygroscopic moisture, feasible fertilizer application time and rate, to fix the time and volume of irrigation, turfgrass visual quality evaluation, turfgrass disease prediction and prevention were reviewed. Most researchers considered the nutrition condition of turf impacted the visual and playing quality of golf course directly and then indirectly influenced most of assistant cultivation such as fertilization, mowing and irrigation and so on. The using of NIRS can detect the nutrient content of turfgrass effectively and estimate the nutrient is excessive or deficient quickly. And then the feasible time and rate of fertilizers can be decided. Comparing with the common judgment ways based on the season fertilization and visual estimation, the using of NIRS can reduce the application of fertilizers on the base of keeping the same turf quality simultaneously. NIRS can analysis many items of soil such as moisture, elements concentration, textures on the spot by the thousands. This method can get lots of cover-all data non-destructively. What's more, NIRS can analysis soil betimes quickly

Nuclear medicine technologists may not have had opportunity to read periodic journals on a regular basis and may feel intimidated by the content, style and jargon used in many journal articles. By becoming familiar with the style of articles and having some grasp of the basic concepts underlying statistical description of data errors and their relation to hypothesis testing, the technologist can begin to appreciate the content in journals. In particular they should appreciate that journal articles are open to debate and do not necessarily represent 'truth' (Au)

In this study, we surveyed the current status, satisfaction and demand of radiologic technologist continuing education for 93 radiologic technologists who participated in the continuing education. To understand the current status and general evaluation and to find out the improvement direction, survey was conducted on 3 categories: participation, satisfaction and demand of continuing education. In addition, we analyzed the continuing education implementation status and the management system by collecting related regulations. As a result, the education completion rates of radiologic technologists from 2010 to 2012 were respectively 42.6%, 43.4% and 34.2%; the rates were similar to other medical technician’s average education completion rates. According to the survey, in case of participation, the most frequent answer was ‘more than five times less than 10 times per year’ with 48.4% and in satisfaction section, the most common answer was ‘Average(3)’ with 34.4%. In demand of continuing education section, 32.8% of the respondents chose ‘Clinical skill training in major field’. In the results of this research, continuing education needs to be managed in the direction of helping radiologists improve their personal ability and self development. Furthermore, to meet the demand of radiologists, the quality of continuing education should be improved to satisfy the educatee

Subtropical urban turfs: Carbon and nitrogen pools and the role of enzyme activity.

Science.gov (United States)

Kong, Ling; Chu, L M

2018-03-01

Urban grasslands not only provide a recreational venue for urban residents, but also sequester organic carbon in vegetation and soils through photosynthesis, and release carbon dioxide through respiration, which largely contribute to carbon storage and fluxes at regional and global scales. We investigated organic carbon and nitrogen pools in subtropical turfs and found that dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) were regulated by several factors including microbial activity which is indicated by soil enzymatic activity. We observed a vertical variation and different temporal patterns in both soil DOC, DON and enzyme activities, which decreased significantly with increasing soil depths. We further found that concentration of soil DON was linked with turf age. There were correlations between grass biomass and soil properties, and soil enzyme activities. In particular, soil bulk density was significantly correlated with soil moisture and soil organic carbon (SOC). In addition, DOC correlated significantly with DON. Significant negative correlations were also observed between soil total dissolved nitrogen (TDN) and grass biomass of Axonopus compressus and Zoysia matrella. Specifically, grass biomass was significantly correlated with the soil activity of urease and β-glucosidase. Soil NO 3 -N concentration also showed negative correlations with the activity of both β-glucosidase and protease but there were no significant correlations between cellulase and soil properties or grass biomass. Our study demonstrated a relationship between soil C and N dynamics and soil enzymes that could be modulated to enhance SOC pools through management and maintenance practices. Copyright © 2017.

2016-12-15

Radiologic technologists currently consist of 31.5% among diagnostic radiation workers in South Korea. Among diagnostic radiation workers, radiologic technologists receive the highest annual and collective doses in South Korea. Comprehensive assessment of the work practices and associated radiation doses from diagnostic radiology procedures should be undertaken for effective prevention for radiologic technologists. Using the national survey, this study aimed (1) to explore the distribution of the work procedures performed by gender, (2) to evaluate occupational radiation exposure by work characteristics and safety compliance, (3) to identify the primary factors influencing high radiation exposure among radiologic technologists in South Korea. This study provided detailed information on work practices, number of procedures performed on weekly basis, and occupational radiation doses among radiologic technologists in South Korea. Average radiation dose for radiologic technologists is higher than other countries, and type of facility, work safety, and wearing lead apron explained quite a portion of increased risk in the association between radiology procedures and radiation exposure among radiologic technologists.

Radiologic technologists currently consist of 31.5% among diagnostic radiation workers in South Korea. Among diagnostic radiation workers, radiologic technologists receive the highest annual and collective doses in South Korea. Comprehensive assessment of the work practices and associated radiation doses from diagnostic radiology procedures should be undertaken for effective prevention for radiologic technologists. Using the national survey, this study aimed (1) to explore the distribution of the work procedures performed by gender, (2) to evaluate occupational radiation exposure by work characteristics and safety compliance, (3) to identify the primary factors influencing high radiation exposure among radiologic technologists in South Korea. This study provided detailed information on work practices, number of procedures performed on weekly basis, and occupational radiation doses among radiologic technologists in South Korea. Average radiation dose for radiologic technologists is higher than other countries, and type of facility, work safety, and wearing lead apron explained quite a portion of increased risk in the association between radiology procedures and radiation exposure among radiologic technologists.

An analysis of successive changes in nematode assemblages in reclaimed waste area offers information about the sensitivity of species or groups of nematodes to specific conditions and ability to colonise new habitats. The study was carried in ash dumps being a by-product of the combustion of hard coal and reclaimed by covering with mineral turf (light loam warp soil) or organic turf (alder peat). In the first 3 years of reclamation diversity of nematodes was low, especially in, the dump covered with mineral turf - Shannon diversity index below 3. Later on the value of Shannon index increased and did not differ from those recorded for meadows in Poland. In the ash dump, reclaimed for a longer time period (8-11 years), the contribution of K strategist species was higher than in the dumps reclaimed for a shorter time period (2-5 years). At the earlier stages of succession bacterivores Acrobeloides, and two fungivores Aphelenchoides and Aphelenchus, predominated. In the ash dump reclaimed longer the dominance of these three genera decreased and some plant feeders achieved high contribution ({gt} 30%). The composition of nematode communities depended. significantly on the period of reclamation, but did not depend either on the soil moisture and pH or on season.

Macroalgal assemblages dominated by the turf-forming alga Phyllophora crispa are described in detail for the first time in the Central Mediterranean Sea. This particular form of algal growth, which comprises an upper mixed layer of multiple algal species with a basal stratum formed by entangled thalli of P. crispa, was observed for the first time in 2012 along the promontory of Punta del Lazzaretto (Giglio Island, Italy). In this study, this assemblage was analysed to document the diversity of macroalgae and invertebrate associated communities and assess their distribution along a depth gradient. The algae forming turfs grow directly on the rock at low depth up to 10-15 m depth, while they grow above P. crispa from 15 m to 35 m depth, resulting in luxuriant beds covering up to 100% of the substrate. Multivariate analysis revealed clear differences regarding algae and invertebrate species richness and abundance between shallow and deep strata because of the dominance of Phyllophora crispa at depths greater than 20 m. The long laminal thalli of P. crispa favoured sessile fauna colonization, while the vagile species were principally linked to the architectural complexity of the turf layer created by the P. crispa, which increased the microhabitat diversity and favoured sediment deposition within the turf layer. The complex structures of these turf assemblages and their widespread distribution along the whole coast of the island suggest a well-established condition of the communities linked to the high natural sedimentation rate observed in the area.

With the exponential increase in minimally invasive fluoroscopically guided interventional radiologic procedures, concern has increased about the health effects on staff and patients of radiation exposure from these procedures. There has been no systematic epidemiologic investigation to quantify serious disease risks or mortality. To quantify all-cause, circulatory system disease and cancer mortality risks in U.S. radiologic technologists who work with interventional radiographic procedures, we evaluated mortality risks in a nationwide cohort of 88,766 U.S. radiologic technologists (77% female) who completed a self-administered questionnaire during 1994-1998 and were followed through 31 December 2003. We obtained information on work experience, types of procedures (including fluoroscopically guided interventional procedures), and protective measures plus medical, family cancer history, lifestyle, and reproductive information. Cox proportional hazards regression models were used to compute relative risks (RRs) with 95% confidence intervals (CIs). Between completion of the questionnaire and the end of follow-up, there were 3,581 deaths, including 1,209 from malignancies and 979 from circulatory system diseases. Compared to radiologic technologists who never or rarely performed or assisted with fluoroscopically guided interventional procedures, all-cause mortality risks were not increased among those working on such procedures daily. Similarly, there was no increased risk of mortality resulting from all circulatory system diseases combined, all cancers combined, or female breast cancer among technologists who daily performed or assisted with fluoroscopically guided interventional procedures. Based on small numbers of deaths (n=151), there were non-significant excesses (40%-70%) in mortality from cerebrovascular disease among technologists ever working with these procedures. The absence of significantly elevated mortality risks in radiologic technologists reporting the

The discretionary range of a radiological technologist and the autonomy on law were investigated by the questionnaire. The degree of satisfaction of work and the domain to lengthen were investigated. Result, the inspection direction change of MRI inspection and the urgent connection at the time of diagnostic imaging unusual discovery is discretion. However, there are no part change and addition of a general photography inspection at discretion. Explanation of the inspection result of a patient is also useless. Moreover, many of troubles are explanation relations, It was much between the doctor or the patient. For the degree of operating satisfactory, definite aim in life is 70 points. There were about 70 points about speciality nature. The degree of discretion has many less than 50 points. On the whole, a female radiological technologist's degree of satisfaction was low. Next, the autonomy of a radiological technologist method was low and many wished a legal revision. Specialization is promoted as a future measure. Diagnostic imaging field advance is lengthened. Improvement in a status of a radiological technologist, Activity fullness of the Japan Association of Radiological Technologists is expected. (author)

Purpose: The purpose of this study was to present ideas to upgrade job performance and improve organizational management by analyzing leadership aspects and organizational cultures of radiological technologist organizations. Method: A questionnaire was used to collect data from 261 radiological technologists working in the city of Busan. Then, SPSS/PC + Win 13 was used to statistically analyze the collected data. One-way ANOVA was adopted to test differences among groups, and multiple regression analyses were conducted to examine the effect of organizational culture and leadership upon organizational effectiveness. Results: First, it was found that radiological technologists stressed consensus most among the 4 types of organizational culture and regarded core transformational leadership as the right type of leadership. Second, regarding the relationship between leadership and organizational effectiveness, transformational leadership had the highest influence upon organizational effectiveness. Third, as for the relationship between organizational culture and organizational effectiveness, it was found that a developmental culture has the highest influence upon organizational effectiveness, followed by a culture of consensus. Conclusion: If transformational leadership and consensual culture are used properly for upgrading job performance in the organization, conflicts among radiological technologists might be reduced, thereby enhancing organizational effectiveness.

Growth chamber and field experiments were carried out to determine the effects of extended photoperiod under low and freezing temperatures on bermudagrass turf dormancy at Bajgah, in the southern part of Iran. The experiment in the growth chamber was conducted with four temperature regimes (15, 7.5, 0 and -7.5°C) and three light durations (8, 12 and 16h) in a completely randomized design with four replications. The field study was conducted in two consecutive years (2008-2009) with three light durations (8, 12 and 16h) in months with natural short day length and arranged in a randomized complete blocks design with three replications. Results in both experiments showed that decreasing temperature and photoperiod decreased verdure fresh and dry weight, shoot height, tiller density, leaf area and chlorophyll and relative water contents (RWC). However, rooting depth and fresh weight of roots increased in the growth chamber. Decreasing the temperature and light duration increased electrolyte leakage and proline content. Reducing sugars increased with decreasing temperature and declined with lowering light duration in both shoots and roots. Starch content of both shoots and roots showed an adverse trend compared to reducing sugars; starch content increased in both shoots and roots in all treatments by shortening the photoperiod. Practically, the problem of bermudagrass turf's dormancy could be solved via increasing the photoperiod in months with short day lengths. This treatment would be efficient and useful for turfgrass managers to apply in landscapes and stadiums. Copyright © 2012 Elsevier GmbH. All rights reserved.

The most important sources of ionizing radiation for general public are medical sources. Good working protocols and radiological protections measurements provided significant reduction of patients and professional doses. Medical users of ionizing radiation are radiological technologists. The purpose of this paper is to point out to several facts and errors in radiation protection educational programs for radiological technologists. Medical College educational program covers main specific topics in radiation protection, but there are some omissions in training process. Radiological technologists must be actively involved in radiation protection. Following ethical standards they will reach higher standards than the law requires

Task-specific monitoring of nuclear medicine technologists' radiation exposure

International Nuclear Information System (INIS)

Smart, R.

2004-01-01

Many studies have demonstrated that the exposure of nuclear medicine technologists arises primarily from radioactive patients rather than from preparation of radiopharmaceuticals. However, in order to devise strategies to reduce staff exposure, it is necessary to identify the specific tasks within each procedure that result in the highest radiation doses. An ESM Eberline FH41B-10 radiation dosemeter, which records the ambient dose equivalent rate, was used to monitor the radiation exposure of a technologist and to record the dose rate in μSv per hour every 32 s throughout a working day. The technologist recorded the procedures that were being performed so that the procedures that resulted in higher doses could be identified clearly. The measured doses clearly showed that the major contributions to the technologist's dose were the following: (1) transferring incapacitated patients from the imaging table to a hospital trolley; (2) difficult injections without syringe shields; and (3) setting up patients for gated myocardial scans. The average dose to the technologist from transferring patients after a bone scan was 0.54 μSv, 40% of the total dose of 1.3 μSv for the complete bone scan procedure. The average dose received injecting 900 MBq of 99 Tc m -HDP using a tungsten syringe shield was 0.57 μSv, but the highest dose was 1.6 μSv, in a patient in whom the injection was difficult. A 0.5 mm lead apron was found to reduce the dose when setting up a patient for a gated stress 99 Tc m -sestamibi myocardial scan by approximately a factor of 2. The average dose per patient for this task was reduced from 1.1 to 0.6 μSv. It is recommended that staff waiting for assistance with patient transfers stand away from the patient, that tungsten syringe shields be used for all radiopharmaceutical injections and that a 0.5 mm lead apron be worn when attending patients containing high activities of 99 Tc m radiopharmaceuticals, such as those having myocardial imaging.

To evaluate risks of hematopoietic and lymphoproliferative malignancies among medical workers exposed to protracted low-to-moderate-dose radiation exposures, a follow-up investigation was conducted in a nation wide cohort of U. S. radiologic technologists. eligible for this study were 71.894 technologists (78% female) certified for at least 2 years during 1926-82, who had responded to a baseline mail questionnaire during 1983-89, were cancer-free except for non-melanoma skin cancer at completion of the questionnaire, and completed a second questionnaire during 1994-98 or died through August 1998. There were 241 technologists with hematopoietic or lymphoproliferative malignancies, including 41 with leukemia subtypes associated with radiation exposures (specifically acute myeloid, acute lymphoid and chronic myeloid leukemias, hereafter designated radiogenic leukemias), 23 with chronic lymphocytic leukemia, 28 with multiple myeloma, 118 with non-Hodgkin lymphoma, and 31 with Hodgkin lymphoma. Of the 241 hematopoietic or lymphoproliferative malignancies identified among radiologic technologists, 85 percent were confirmed by medical records or death certificates, including 98 percent of radiogenic leukemia. Risks of the hematopoietic or lymphoproliferative malignancies were evaluated in relation to questionnaire-derived information on employment as a radiologic technologist, including procedures, work practices, and protective measures. cox proportional hazards regression analysis was used to compute relative risks and 95% confidence intervals, using age at diagnosis as the response, stratifying at baseline for birth cohort in 5-year intervals, and adjusting for potential confounding. Risks were not increased for any of the hematopoietic or lymphoproliferative neoplasms according to year first worked or total duration of years worked as radiologic technologist. For the combined radiogenic leukemias, risks rose significantly with an increasing number of years worked

Evaluation of Turf-Grass and Prairie-Vegetated Rain Gardens in a Clay and Sand Soil, Madison, Wisconsin, Water Years 2004-08

Selbig, William R.; Balster, Nicholas

2010-01-01

The U.S. Geological Survey, in cooperation with a consortium of 19 cities, towns, and villages in Dane County, Wis., undertook a study to compare the capability of rain gardens with different vegetative species and soil types to infiltrate stormwater runoff from the roof of an adjacent structure. Two rain gardens, one planted with turf grass and the other with native prairie species, were constructed side-by-side in 2003 at two locations with different dominant soil types, either sand or clay. Each rain garden was sized to a ratio of approximately 5:1 contributing area to receiving area and to a depth of 0.5 foot. Each rain garden, regardless of vegetation or soil type, was capable of storing and infiltrating most of the runoff over the 5-year study period. Both rain gardens in sand, as well as the prairie rain garden in clay, retained and infiltrated 100 percent of all precipitation and snowmelt events during water years 2004-07. The turf rain garden in clay occasionally had runoff exceed its confining boundaries, but was still able to retain 96 percent of all precipitation and snowmelt events during the same time period. Precipitation intensity and number of antecedent dry days were important variables that influenced when the storage capacity of underlying soils would become saturated, which resulted in pooled water in the rain gardens. Because the rooftop area that drained runoff to each rain garden was approximately five times larger than the area of the rain garden itself, evapotranspiration was a small percentage of the annual water budget. For example, during water year 2005, the maximum evapotranspiration of total influent volume ranged from 21 percent for the turf rain garden in clay to 25 percent for the turf rain garden in sand, and the minimum ranged from 12 percent for the prairie rain garden in clay to 19 percent for the prairie rain garden in sand. Little to no runoff left each rain garden as effluent and a small percentage of runoff returned to the

The Future of Sleep Technology: Report from an American Association of Sleep Technologists Summit Meeting

Science.gov (United States)

Brooks, Rita; Trimble, Melinda

2014-01-01

The American Association of Sleep Technologists (AAST) Board of Directors hosted a Sleep Technology Summit on September 21, 2013 with the goals of identifying changes in the delivery of diagnostic and treatment services to sleep disorders patients, predicting the impact on sleep technologists, identifying new roles for sleep technologists, and determining appropriate education to prepare technologists for the future. A carefully chosen panel of speakers focused on the business skills necessary to provide care cost effectively and the clinical skills that will be essential for the technologist of the future to help care for patients with sleep disorders. A group of selected leaders, educators, and industry professionals reviewed the current state of affairs and examined opportunities to sustain the profession and define the role of the sleep technologist of the future. Facilitated group discussions of these critical topics followed each session. There was a clear consensus that regulatory and economic pressures are changing the way sleep disorders patients are diagnosed and treated. Private insurers are requiring pre-authorization for laboratory sleep studies and are incentivizing home sleep testing for most patients suspected of obstructive sleep apnea. Reimbursement for home testing will be lower than for laboratory testing, and further reductions in overall reimbursement are anticipated. These factors will almost certainly reduce the need for technologists to perform laboratory diagnostic studies and pressure sleep centers to reduce payrolls. Remaining laboratory patients will have more complicated sleep disorders, have more comorbidity, and require a higher level of care than most of the patients currently tested in sleep centers. Testing these patients will require technologists with a higher level of training, experience, and sophistication. A second area of consensus was that the focus in medicine is changing from diagnosis to outcomes. New models of

Patterson, Heather

2002-01-01

The Distance Assisted Training Programme for Nuclear Medicine Technologists (DAT) has been developed and coordinated through West mead Hospital, Sydney and directed under the auspices of the International Atomic Energy Agency (IAEA). The objective of the program is to provide primarily developing countries with teaching resources for development of technologist education and a framework for the delivery of training courses that can be adapted to best suit local need. Careful planning and development of learning materials, translation to several languages and program implementation have resulted in >400 technologists in 24 countries currently participating in the course of study within Asia, Latin America and Africa. The development and implementation of suitable assessment techniques has provided a structure for technologists to attain a common basic standard in competencies across the regions. Graduates have better opportunities to further their education as well as contribute to improved use of advancing technologies in nuclear medicine (Au)

A work observation study of nuclear medicine technologists: interruptions, resilience and implications for patient safety.

Larcos, George; Prgomet, Mirela; Georgiou, Andrew; Westbrook, Johanna

2017-06-01

Errors by nuclear medicine technologists during the preparation of radiopharmaceuticals or at other times can cause patient harm and may reflect the impact of interruptions, busy work environments and deficient systems or processes. We aimed to: (a) characterise the rate and nature of interruptions technologists experience and (b) identify strategies that support safety. We performed 100 hours of observation of 11 technologists at a major public hospital and measured the proportions of time spent in eight categories of work tasks, location of task, interruption rate and type and multitasking (tasks conducted in parallel). We catalogued specific safety-oriented strategies used by technologists. Technologists completed 5227 tasks and experienced 569 interruptions (mean, 4.5 times per hour; 95% CI 4.1 to 4.9). The highest interruption rate occurred when technologists were in transit between rooms (10.3 per hour (95% CI 8.3 to 12.5)). Interruptions during radiopharmaceutical preparation occurred a mean of 4.4 times per hour (95% CI 3.3 to 5.6). Most (n=426) tasks were interrupted once only and all tasks were resumed after interruption. Multitasking occurred 16.6% of the time. At least some interruptions were initiated by other technologists to convey important information and/or to render assistance. Technologists employed a variety of verbal and non-verbal strategies in all work areas (notably in the hot-lab) to minimise the impact of interruptions and optimise the safe conduct of procedures. Although most were due to individual choices, some strategies reflected overt or subliminal departmental policy. Some interruptions appear beneficial. Technologists' self-initiated strategies to support safe work practices appear to be an important element in supporting a resilient work environment in nuclear medicine.

Changes in habitat complexity negatively affect diverse gastropod assemblages in coralline algal turf.

Science.gov (United States)

Kelaher, B P

2003-05-01

The physical structure of a habitat generally has a strong influence on the diversity and abundance of associated organisms. I investigated the role of coralline algal turf structure in determining spatial variation of gastropod assemblages at different tidal heights of a rocky shore near Sydney, Australia. The structural characteristics of algal turf tested were frond density (or structural complexity) and frond length (the vertical scale over which structural complexity was measured). This definition of structural complexity assumes that complexity of the habitat increases with increasing frond density. While frond length was unrelated to gastropod community structure, I found significant correlations between density of fronds and multivariate and univariate measures of gastropod assemblages, indicating the importance of structural complexity. In contrast to previous studies, here there were negative relationships between the density of fronds and the richness and abundance of gastropods. Artificial habitat mimics were used to manipulate the density of fronds to test the hypothesis that increasing algal structural complexity decreases the richness and abundance of gastropods. As predicted, there were significantly more species of gastropods in loosely packed than in tightly packed turf at both low- and mid-shore levels. Despite large differences between gastropod assemblages at different tidal heights, the direction and magnitude of these negative effects were similar at low- and mid-shore levels and, therefore, relatively independent of local environmental conditions. These novel results extend our previous understanding of the ecological effects of habitat structure because they demonstrate possible limitations of commonly used definitions of structural complexity, as well as distinct upper thresholds in the relationship between structural complexity and faunal species richness.

Taylor, Jeffrey B; Nguyen, Anh-Dung; Griffin, Janet R; Ford, Kevin R

2018-06-01

Metatarsal and midfoot injuries are common in American football. Footwear design may influence injury rates by altering plantar foot loading patterns in these regions. The purpose of this study was to determine the effect of cleat design on in-shoe plantar foot loading during a football-specific, resisted pushing task. Twenty competitive football players (age 14.7 ± 1.8 years, height 1.72 ± 0.10 m, and mass 71.8 ± 26.9 kg) completed three trials of pushing a weighted sled at maximal effort in a standard shoe (CLEAT) and artificial turf-specific shoe (TURF), with flexible in-shoe force measuring insoles. Repeated measures ANOVAs identified mean differences in maximum force and relative load under all regions of the foot. Results showed higher forces in the CLEAT under the medial (p < 0.001) and lateral (p = 0.004) midfoot, central (p = 0.007) and lateral (p < 0.001) forefoot, and lesser toes (p = 0.01), but lower forces in the hallux (p = 0.02) compared to the TURF shoe. Additionally, relative loading was higher in the CLEAT under the medial (p < 0.001) and lateral (p = 0.002) midfoot and lateral (p < 0.001) forefoot, but lower in the medial forefoot (p = 0.006) and hallux (p < 0.001) compared to the TURF shoe. The two shoes elicited distinct plantar loading profiles and may influence shoe selection decisions during injury prevention or rehabilitation practices.

The retrospective cohort study of 'Cancer incidence among persons, working at ionizing radiation environment' was performed. The cohort consisted of 2034 persons (13.82% males and 86.18% females). Among them 475 were radiologists (doctors), 868 - radiologic technologists (all of them females) and 470 nurses (cleaners in radiology departments). The members of the cohort were followed -up retrospectively from 01.01.1978 until 31.12.1977. Standard Incidence Ratio for all cancers in the cohort of female radiologic technologists was 1,31 [0,90-1,85], of female nurses -1,99 [1,26-2,99]. The size of cohorts and follow-up period were too small for site - specific analysis of cancer incidence. (author)

Conclusion: These findings provide some support for the use of AT in female football, with no evidence to suggests that there is an increased risk of injury when performing on an artificial turf. The ankle response was less clear and further research is warranted. This initial study provides a platform for more detailed analysis, and highlights the importance of exploring the biomechanical changes in performance and injury risk with the introduction of AT.

It is becoming increasingly important for today's medical technologists to receive proper training on the safety of medical treatment and healthcare in order to accommodate the rapid changes and advancement in medical technology. In particular, because of the increase of hospital-acquired infections, the role of medical technologists involved in infection control has become much more important. In addition, particularly in Japan, the career options available to students graduating with a degree in medical technology have become much more diverse, ranging from research laboratories to clinical services; however, undergraduate education for medical technologists is limited. It is therefore deemed necessary for undergraduate students to be provided with adequate training from their universities by offering a wider selection of classes in this subject area. In this paper, we summarize our preliminary findings on the trial lessons that are offered to medical technology students in their microbiology class. These lessons are designed to enhance students' academic potential and to engage their interest.

People who live in Taiwan are getting more and more afraid of radiation. Sometimes the phobia results from distorted knowledge. Radiology technologists, in one hand, are more well-educated in radiation and, in the other hand, have more chance to expose to radiation when they are operating radiation producing medical instruments in their daily life. So we are interested in whether they have enough knowledge to protect themselves. We pick up the radiology technology board examination to make the questionnaire for this study. The population is the radiology technologists who work at department of diagnostic radiology, of radiation therapy and nuclear medicine in medical centers. Statistics is then used to see the relationship between knowledge and the factors including gender, age and career period. Based on statistics, we find out that there is significant correlation between the knowledge with age or education level. Elder or lower education level ones has worse knowledge. Continued education may be highly recommended for radiology technologists to avoid occupational radiation injury. (author)

Analysis and comparison of modern methods of turf irrigation, verifying the capability of existing information systems through the use of numerical modeling

The automated irrigation of parks and gardens in public areas has become more and more a common practice due to the many benefits it brings in terms of improving the quality of urban green areas. Since this practice requires significant volumes of water, and this becomes increasingly scarce and expensive, it is necessary that the design criteria and use management aim at maximizing the irrigation efficiency. There are conflicting relationship and competition between trees and turf for several reasons. On one hand the different irrigation needs can cause excess water in the root zones of the trees, on the other hand the surface roots of trees and the shade created from the leaves by the dripline (projection line of the canopy) determine an unfavorable area to the growth of the turf because of light factor. It follows that for an optimal design of an irrigation system is necessary to separate the turf areas from trees, with the disadvantage of considerably complicate the geometries of the sprinklers. Each tree or group of trees need to be associated to a not irrigated area. This problem seems not to have a specifically bibliographical evidence, although there are operating standards primarily used to define buffer zones for trees from constructions (British Standard 5837:2005). Ideally, a high number of sprinklers is required to follow the shape of the areas perfectly. Hence, an additional step is necessary to simplify these geometries, identifying a correct scheme for the sprinkler spacing. Such a sequence of geometric operations has been tested on the "Indro Montanelli" park in Milan, obtaining a reduction of the irrigated area of 47% and a water saving of around 30%. We intend to continue the research applying the model to other parks, verifying its applicability in different situations.

Qualitative research is lacking regarding the experiences of magnetic resonance imaging (MRI) technologists and their involvement in workplace safety practices. This article provides a gateway to explore, describe and document experiences of MRI technologists in New Zealand (NZ) pertaining to intra-orbital metallic foreign body (IMFB) safety practices. This phenomenological study describes the experiences of seven MRI technologists all with a minimum of 5 years' NZ work experience in MRI. The MRI technologists were interviewed face-to-face regarding their professional IMFB workplace experiences in order to explore historical, current and potential issues. Findings demonstrated that aspects of organization and administration are fundamentally important to MRI technologists. Varying levels of education and knowledge, as well as experience and skills gained, have significantly impacted on MRI technologists’ level of confidence and control in IMFB practices. Participants’ descriptions of their experiences in practice regarding decision-making capabilities further highlight the complexity of these themes. A model was developed to demonstrate the interrelated nature of the themes and the complexity of the situation in totality. Findings of this study have provided insight into the experiences of MRI technologists pertaining to IMFB safety practices and highlighted inconsistencies. It is hoped that these findings will contribute to and improve the level of understanding of MRI technologists and the practices and protocols involved in IMFB safety screening. The scarcity of available literature regarding IMFB safety practices highlights that more research is required to investigate additional aspects that could improve MRI technologists’ experiences.

Bystander Tactics: Life on Turf in Karachi

Directory of Open Access Journals (Sweden)

Tania Ahmad

2012-03-01

Full Text Available This article posits an analytic of the bystander, as a supplement to studies of perpetrators and victims, in relation to political affiliation, mobilization and violence in Karachi. In particular, I use ethnographic findings to elucidate the tactics of anticipation used by Karachi residents of neighborhoods widely considered the turf of the Muttahida Qaumi Movement (MQM. The examples of students’ and teachers’ reactions to a college rumble between rival groups, parents’ attempts to keep their sons from being recruited into party politics, and young people confident in their ability to navigate an economy of affiliation demonstrate a range of bystander tactics, in which subjection and subversion are aligned. Although metanarratives of democratization frequently elide the everyday activity of standing by, it constitutes a pervasive mode of participation in Karachi’s political landscape.

The objective of this study was to investigate representative occupational characteristics and radiation exposure for South Korean radiologic technologists. The authors conducted a national survey by stratified sampling of South Korean administrative districts and types of medical facilities. A total of 585 technologists were surveyed, and survey data were linked with dosimetry data from the National Dose Registry. A total of 73 % of radiologic technologists sampled were male, 62 % were younger than age 40 and 86.5 % began employment after 1990. The most frequent practices among radiologic technologists were diagnostic routine X-ray followed by computed tomography (CT) and portable X-ray. Male workers were more frequently involved in CT, portable X-ray and interventional radiology whereas female workers carried out most mammography procedures. The average annual effective dose was 2.3 mSv for male and 1.3 mSv for female workers. The dose was significantly higher for workers in the provinces and those who had recently started work.

This study attempts to provide basic information on overseas employment to the radiological technologists and students majoring in radiology in Korea who consider the overseas employment by investigating the job consciousness for radiological technologists in Canada and Australia which have a high level of interest for overseas employment and want to compare their status with that of Korean radiological technologists. This study was performed by visiting hospitals such as Prince George Regional Hospital, 1475 Edmonton Street, Prince George, BC, Canada on August 13, 2007, Alfred Hospital, Commercial Road Melbourne 3004, Australia on August 4, 2008, and other Korea hospitals that show the similar scale as Canada and Australia on September 10, 2007. The results were summarized as follows : 1. Differences were observed in this sexual composition, such as 18 males (90%) in Korea, 14 females (73.7%) in Canada, and 25 females in Australia (86.2%). 2. The item of 'aptitude' which is one of the most important criteria, showed the highest level in Korea, Canada, and Australia, and the second most considered item was 'salary'. 3. In the values in jobs, the items of 'economic self-sufficiency', 'recognized by others', and 'establishing a social position' represented high levels in Korea, and the items of 'like the job itself', 'establishing self-actualization', 'feel the meaning of life', and 'make new friends' showed high levels in Canada and Australia. 4. Regarding the item of 'a job is important as much as a marriage', 'Yes' showed high level in Korea, and 'No' showed high levels in Canada and Australia. 5. Radiological technologists in Korea demonstrated a low level in the job consciousness compared to those of Canada and Australia. Although this study shows some limitations for showing whole idea of radiological technologists due to the lack of the scope in samples for each country as a practical manner, this study can be regarded significant to compare some countries

2007-01-01

Full text: Therapeutic doses of I-131 for treatment of thyroid cancer are administered orally in liquid or capsule form. During the last few years, a total number of patients loaded in our isolation ward increased from 4 to 10 patients per week. When considering radiation safety precautions for attending technologists, it is preferable to use the dose in capsules. The purpose of this study is to compare radiation exposure to nuclear medicine technologists from administering I-131 therapy dosages in capsules and in liquid form in a closed system. Materials and Methods: Three year radiation exposure to technologists during I-131 administration was analyzed. From January 2004 to June 2005 dose administration was in liquid form (n=263) and from July 2005 to February 2007 in capsules (n=541). Radiation dose assessment was performed with an electronic personal dosimeter (PDM 112). The dose rate in μSv and time spent per patient were recorded. Results: Dose received per patient when I-131 was given in a liquid was 3.50 ± 1.67 μSv and 1.17 ± 0.66 μSv when given in capsules. Compared with the use of a liquid, capsules significantly reduced radiation dose to technologists by 66% (P < 0.001). These doses received depended not only on the administered activity but also on the time, distance and shielding. Time spent per patient, including a brief visit before the time of dosing to explain the procedure and answer questions was reduced slightly from 4.4 ± 2.2 to 3.7 ± 1.8 minutes (P < 0.01). These correspond to a reduction in a yearly dose to 1 technologist by 40%, from 0.63 mSv to 0.38 mSv from dosing to 175 and 325 patients respectively. Conclusions: The measured doses clearly showed that handling of I-131 therapy dosages either in a liquid form or capsules are not the major contributors to the technologist's radiation exposure in routine clinical practice. However, one has to be cautious and follow good work practice to avoid risk of radiation exposure and radioiodine

Full Text Available Background The number of casualties and critically ill patients referred to radiology departments increased during the past decade, which caused the risk of cardiac arrest in radiology departments to increase considerably. Objectives The current study aimed to evaluate the knowledge and attitude of radiology technologists regarding Cardiopulmonary Resuscitation (CPR. Patients and Methods After approval a cross sectional study was designed. Ninety five radiology technologists (male and female were selected in four tertiary referral hospitals in Ahvaz, Iran. Accordingly, 87 radiologic technologists of which agreed to participate in the study. The researchers developed a questionnaire. The questionnaire consisted of three distinct sections including demographic data, attitude, and technical knowledge questions. Reliability of the technical knowledge questions were evaluated using Cronbach’s alpha (76%. Data collection was performed using interview method. Results Of the total 87 questionnaires, one was incomplete. None of the participants had attended a training program since employment. The average scores of attitude towards CPR and technical knowledge were 80 ± 8.9 and 8.8 ± 2.3, respectively. A correlation was observed between age and work experience (r = 0.866, P ≤ 0.0001, age and technical knowledge (r = 0.380, P ≤ 0.0001, work experience and technical knowledge (r = 0.317, P = 0.003, and attitude and technical knowledge (r = 0.397, P ≤ 0.0001. Also a correlation was observed between work experience and attitude (r = 0.385, P ≤ 0.0001. No significant difference was observed between male and female subjects’ technical knowledge (P ≥ 0.05 and attitude (P ≥ 0.05. Conclusions It can be concluded that, although the attitude of participants towards CPR was positive in general, their technical knowledge was poor. This finding should urge decision-makers to consider delivering in-service training courses to radiology technologists

Medical radiation workers were among the earliest occupational groups exposed to external ionizing radiation due to their administration of a range of medical diagnostic procedures. Ionizing radiation is a confirmed human carcinogen for most organ sites. This study, therefore, was aimed to estimate lifetime cancer risk from occupational exposure among radiologic technologists that has been recruited in 2012-2013. Our findings showed a small increased cancer risk in radiologic technologists from their occupational radiation exposure in Korea. However, continuous dose monitoring and strict regulation on occupational safety at the government level should be emphasized to prevent any additional health hazards from occupational radiation exposure.

To describe the study design, methods, and baseline results of a prospective cohort of radiologic technologists which we have initiated in South Korea. The cohort participants were enrolled through a self-administered questionnaire survey administered from April 2012 to May 2013. Survey data were linked with radiation dosimetry, a cancer registry, and health insurance data by personal identification numbers. A nationwide representative survey was also conducted using a stratified random sampling design with face-to-face interviews. A total of 12,387 radiologic technologists were enrolled, which accounted for approximately 63% of all diagnostic radiologic technologists working in South Korea. For nationwide survey, 585 workers were interviewed using the detailed questionnaire, and buccal cells were also collected by scraping the inside of the cheek. The majority of study subjects were under 50-year-old and male workers. The average annual effective dose of radiation declined both men (from 2.75 to 1.43 mSv) and women (from 1.34 to 0.95 mSv) over the period of 1996-2011. A total of 99 cancers (66 cancers in men and 33 in women) were reported from 1992 to 2010. The standardized incidence ratio of all cancer combined was significantly lower in men (SIR = 0.75, 95% CI 0.58-0.96) than general population, but the ratios for thyroid cancer were significantly higher than expected among both men and women. This cohort provides comprehensive information on work activities and health status of diagnostic radiologic technologists. In addition, the nationwide representative sample provides unique opportunities compared with previous radiologic technologist studies.

Worldwide increase in the prevalence of abnormal anthropometric indices (i.e., body mass index (BMI), and waist circumference (WC)) are associated with increased risk of death and adverse health outcomes which causes great burden in public health. Studies on the association between radiation exposure and altered anthropometric indices reported both positive and negative associations in atomic bomb and childhood cancer survivors. We have initiated a radiologic technologists health study to investigate occupational radiation exposure and their health effects. Therefore, this study aims to investigate the association between occupational radiation dose with BMI and WC in radiologic technologists in South Korea. These results explain that occupational radiation exposure can possibly alter BMI and WC. Therefore, further study is required to verify the prospective causal effect of radiation exposure on anthropometric indices.

According to the astonishing progress of medical science, the medical roles of the radiologic technologist are increasing gradually and specializing highly. However, there are the wide disagreements the actual roles of the radiologic technologists at clinics and the relating rules of the medical law. Therefore, it is required that the medical law should be corresponded with the actual state. To solve these problems. This study has proceeded to make the survey of the present medical law and has tried to offer the most suitable theories to the actual state. This study includes the survey of relevant professional literatures. The major contents of this study are as follows. First, medical technician is written (in Chinese character) at the present medical technician law, and that word is written wrong. So, it should be replaced with Therefore, radiologic technologist should be written Second, the relations between the doctor and the radiologic technologist should be written the 'request or other words' instead of 'direction' Third, in spite of the rules of the present medical law, the medical act of radiologic technologist at clinics should be belonging to the boundary of medical practice. Forth, to present the appropriate medical service to the patients, legal status of radiologic technologist as a member of medical team should be established. Fifth, it is desired that Magnetic Resonance Imaging Technology as a business of radiologic technologist should be provided for in the medical law

In arid and semi-arid regions, the use of treated wastewater for landscape irrigation is becoming common practice and a significant asset to conserve potable water supplies. Public interest and lack of field-scale data are leading to a concern that compounds found in reuse water could persist in the environment and contaminate groundwater. As part of a larger study, 2-yr experiments were conducted in CA and NV, where reuse water was the primary source of non-ambient water input. A total of 13 compounds were studied, all originating in irrigation water applied to soil covered in turf or left bare. The target compounds included atenolol, atorvastatin, carbamazepine, diazepam, diclofenac, fluoxetine, gemfibrozil, ibuprofen, meprobamate, naproxen, primidone, sulfamethoxazole, triclosan, and trimethoprim. Analytical protocols for all compounds (detection at ng/L range) were established before the study commenced. The goals of the research were to increase available data on the fate and transport of these target compounds in turfgrass/soil systems, and to use these data to assess long-term risk from using water containing these compounds. Experiments conducted at two scales are discussed here: lysimeter-scale and field-scale. At the lysimeter-scale, 24 drainage lysimeters (120 cm thick) were exposed to treated wastewater as an irrigation source. Lysimeters varied by soil type (two types), soil cover (bare- versus turf-covered) and leaching fraction (5% and 25%). Upper and lower boundary conditions were monitored throughout the study. Water samples were collected periodically after water breakthrough. After the study, soil samples were analyzed for compound mass, allowing compound mass balance and removal to be assessed. At the field-scale, passive drain gages (Decagon Devices) were installed in triplicate in fairways at four operational golf courses, one in NV and three in CA, all with histories of using treated wastewater. The gages measure water fluxes through the 60

Full Text Available The professional content of sleep medicine has grown significantly over the past few decades, warranting the recognition of sleep medicine as an independent specialty. Because the practice of sleep medicine has expanded in Saudi Arabia over the past few years, a national regulation system to license and ascertain the competence of sleep medicine physicians and technologists has become essential. Recently, the Saudi Commission for Health Specialties formed the National Committee for the Accreditation of Sleep Medicine Practice and developed national accreditation criteria. This paper presents the newly approved Saudi accreditation criteria for sleep medicine physicians and technologists.

Full Text Available The paper describes the results of research aimed at assessing the current conditions related to clinical laboratory technologist professional development. A descriptive cross study covering the period between November 2013 and January 2014 is presented. Several techniques for identifying and hierarchically arranging professional developmental related problems were used to study a sample at the Faculty of Health Technology of the Medical University “Carlos Juan Finlay”. The study involved heads of teaching departments and methodologists of health care technology specialties; moreover a survey and a content test were given graduate clinical laboratory technicians. The authors reached at the conclusion that clinical laboratory technologist professional development is limited and usually underestimate the necessities and interests of these graduates. Likewise, a lack of systematization and integration of the biomedical basic sciences contents and the laboratory diagnosis is noticeable.

There is an urgent need to quantify the impacts of artisanal fisheries and define management practices that allow for the recovery and conservation of exploited stocks. The extent of illegal catch is particularly critical as a driver of overexploitation in artisanal fisheries. However, the lack of data at proper spatial scales limits the evaluation of illegal fishing and effectiveness of management practices. We used a catch curve analysis to estimate total instantaneous mortality as a proxy of fishing pressure in the artisanal benthic fishery in central Chile. We compared the patterns of total mortality in fishing grounds under the well-studied territorial use rights for fisheries system (TURF) immersed in a landscape of open access areas (OAA; no access restriction), and from these patterns determined the extent of illegal fishing in open access areas focusing on the two most frequently extracted resources: locos (Concholepas concholepas) and keyhole limpets (Fissurella spp.). The beauty of this seascape is the presence of the no-take (NT) area of Las Cruces as control (no fishing), allowing us to estimate natural mortality. Loco exploitation is banned in OAAs. However, loco mortality in OAAs was 92% higher than in the NT, and 42% higher than in TURFs. Keyhole limpet mortality was similar between TURFs and the NT, but doubled in OAAs. We also found strong differences in mortality among fishing grounds with the same level of protection (i.e. TURFs), and over time. Our results highlight (a) the high level of illegal fishing that may occur in artisanal fisheries under traditional management regimes, and (b) that TURFs can be effective to reduce fishing mortality. However, large variability among TURFs suggests the need for a deeper understanding of the drivers of success of TURFs. PMID:28666013

Full Text Available Christina C Mendat,1 Dave Mislan,2 Lisa Hession-Kunz2 1Human Factors MD, Charlotte, NC, 2Hologic Inc., Marlborough, MA, USA Abstract: A sample size of 280 certified mammography technologists were surveyed to understand what factors affect patient discomfort during breast imaging. Given mammography technologists’ level of patient involvement, they are uniquely positioned to observe factors that affect patient comfort. The findings suggest that according to technologists, multiple factors, including patient ethnicity, breast density, previous biopsy and lumpectomy experience, as well as psychological factors, impact breast discomfort during mammography. Additionally, with respect to imaging protocols, technologists attributed 80% of moderate-to-extreme discomfort to “length of compression time” (27% and “compression force” (53%. Technologists also attributed “pinching at chest wall” and “hard edges of breast platform” to “very high” discomfort significantly more times (P<0.05 than “coolness and edges of paddle”. These findings confirm some of what has been reported to date and challenge other findings. Given that recent decline in breast cancer mortality has been attributed to improvements in early detection and treatment, approaches to reduce discomfort should be considered in order to promote screening compliance. Although more research is needed, it is apparent that the patient experience of comfort and pain during mammography is an area warranting increased research and solutions.

This study attempts to provide basic information on overseas employment to the radiological technologists and students majoring in radiology in Korea who consider the overseas employment by investigating the job consciousness for radiological technologists in Canada and Australia which have a high level of interest for overseas employment and want to compare their status with that of Korean radiological technologists. This study was performed by visiting hospitals such as Prince George Regional Hospital, 1475 Edmonton Street, Prince George, BC, Canada on August 13, 2007, Alfred Hospital, Commercial Road Melbourne 3004, Australia on August 4, 2008, and other Korea hospitals that show the similar scale as Canada and Australia on September 10, 2007. The results were summarized as follows : 1. Differences were observed in this sexual composition, such as 18 males (90%) in Korea, 14 females (73.7%) in Canada, and 25 females in Australia (86.2%). 2. The item of 'aptitude' which is one of the most important criteria, showed the highest level in Korea, Canada, and Australia, and the second most considered item was 'salary'. 3. In the values in jobs, the items of 'economic self-sufficiency', 'recognized by others', and 'establishing a social position' represented high levels in Korea, and the items of 'like the job itself', 'establishing self-actualization', 'feel the meaning of life', and 'make new friends' showed high levels in Canada and Australia. 4. Regarding the item of 'a job is important as much as a marriage', 'Yes' showed high level in Korea, and 'No' showed high levels in Canada and Australia. 5. Radiological technologists in Korea demonstrated a low level in the job consciousness compared to those of Canada and Australia. Although this study shows some limitations for showing whole idea of radiological technologists due to the lack of the scope

This study assesses the inter-observer variability of mammographic breast density scoring (BDS) between technologists and radiologists and evaluates the effect of technologist patient referral on the load of adjuvant ultrasounds. In this IRB approved study, a retrospective analysis of 503 prospectively acquired, random mammograms was performed between January and March 2014. Each mammogram was evaluated for BDS independently and blindly by both the performing technologist and the interpreting radiologist. Statistical calculation of the Spearman correlation coefficient and weighted kappa were obtained to evaluate the inter-observer variability between technologists and radiologists and to examine whether it relates to the technologist's seniority or women's age. The effect on the load of adjuvant ultrasounds was evaluated. 10 mammography technologists and 7 breast radiologists participated in this study. BDS agreement levels between technologists and radiologists were in the fair to moderate range (kappa values: 0.3-0.45, Spearman coefficient values: 0.59-0.65). The technologists markedly over-graded the density compared to the radiologists in all the subsets evaluated. Comparison between low and high-density groups demonstrated a similar trend of over-grading by technologists, who graded 51% of the women as having dense breasts (scores 3-4) compared to 27% of the women graded as such by the radiologists. This trend of over grading breast density by technologists was unrelated to the women's age or to the technologists' seniority. Mammography technologists over-grade breast density. Technologists' referral to an adjuvant ultrasound leads to redundant ultrasound studies, unnecessary breast biopsies, costs and increased patient anxiety. Copyright © 2016 Elsevier Ireland Ltd.

To describe the study design, methods, and baseline results of a prospective cohort of radiologic technologists which we have initiated in South Korea. The cohort participants were enrolled through a self-administered questionnaire survey administered from April 2012 to May 2013. Survey data were linked with radiation dosimetry, a cancer registry, and health insurance data by personal identification numbers. A nationwide representative survey was also conducted using a stratified random sampling design with face-to-face interviews. A total of 12,387 radiologic technologists were enrolled, which accounted for approximately 63 % of all diagnostic radiologic technologists working in South Korea. For nationwide survey, 585 workers were interviewed using the detailed questionnaire, and buccal cells were also collected by scraping the inside of the cheek. The majority of study subjects were under 50-year-old and male workers. The average annual effective dose of radiation declined both men (from 2.75 to 1.43 mSv) and women (from 1.34 to 0.95 mSv) over the period of 1996-2011. A total of 99 cancers (66 cancers in men and 33 in women) were reported from 1992 to 2010. The standardized incidence ratio of all cancer combined was significantly lower in men (SIR = 0.75, 95 % CI 0.58-0.96) than general population, but the ratios for thyroid cancer were significantly higher than expected among both men and women. This cohort provides comprehensive information on work activities and health status of diagnostic radiologic technologists. In addition, the nationwide representative sample provides unique opportunities compared with previous radiologic technologist studies.

Turf algae-mediated coral damage in coastal reefs of Belize, Central America

Wild, Christian; Jantzen, Carin; Kremb, Stephan Georg

2014-01-01

Many coral reefs in the Caribbean experienced substantial changes in their benthic community composition during the last decades. This often resulted in phase shifts from scleractinian coral dominance to that by other benthic invertebrate or algae. However, knowledge about how the related role of coral-algae contacts may negatively affect corals is scarce. Therefore, benthic community composition, abundance of algae grazers, and the abundance and character of coral-algae contacts were assessed in situ at 13 Belizean reef sites distributed along a distance gradient to the Belizean mainland (12–70 km): Mesoamerican Barrier Reef (inshore), Turneffe Atoll (inner and outer midshore), and Lighthouse Reef (offshore). In situ surveys revealed significantly higher benthic cover by scleractinian corals at the remote Lighthouse Reef (26–29%) when compared to the other sites (4–19%). The abundance of herbivorous fish and the sea urchin Diadema antillarum significantly increased towards the offshore reef sites, while the occurrence of direct coral-algae contacts consequently increased significantly with decreasing distance to shore. About 60% of these algae contacts were harmful (exhibiting coral tissue damage, pigmentation change, or overgrowth) for corals (mainly genera Orbicella and Agaricia), particularly when filamentous turf algae were involved. These findings provide support to the hypothesis that (turf) algae-mediated coral damage occurs in Belizean coastal, near-shore coral reefs.

This study explored several agenda related to license system, education, professional work of radiological technologists (RTs) and a transition process of law for them to investigate a developmental strategy of RTs as a professional career. The results are as followings: 1. The national license system for RTs was started from 1965, 1965-1972 x-ray technicians (medical assistance), 1973-present (2006) radiotechnologist (medical technologist) since then. 2. The average pass ratio of national license examination (1965-2006) for RTs was 46.6%. The method, subjects and level of the examination should be improved. 3. The education term for RTs has been changed since 1963; 1963-1990 two year college. 1991-1999 three year college, 2000-2006 four year and three year college depending on universities and colleges. As of 2006, there are twelve 4-year universities and eighteen 3-year colleges. The total number of new students were 1,965. 4. The new developmental paradigm should be made for technology education of RTs corresponding to the development of medicine and science. 5. The qualification system of clinical specialists in radio-technology field needs to be operated not by the non-governmental body (The-Korean Radiological Technologists Association) but by the governmental body. 6. The vertical relationship among RTs, doctors and other medical workers should be rebuilt through the revision of law. Especially, doctors and dentists 'guidance authority' for RTs should be changed to 'request authority'. 7. The service extent of RTs should be extended in medical fields corresponding to professional work of RTs and a revision of the law needed for this situation

The Effect of Filamentous Turf Algal Removal on the Development of Gametes of the Coral Orbicella annularis

Macroalgae and filamentous turf algae (FTA) are abundant on degraded coral reefs, and the reproductive responses of corals may indicate sub-lethal stress under these conditions. The percentage of gametogenic stages (PGS) and the maximum diameter of eggs (MDE; or egg size) of Orbicella annularis were used to evaluate the effect of long- (7–10 months) and short-term (2.5 months) FTA removal (treatments T1 and T2, respectively) at both the beginning (May) and the end (August) of gametogenesis. Ramets (individual lobes of a colony) surrounded by FTA (T3) or crustose coralline algae (CCA; T4) were used as controls. The removal of FTA enhanced the development of gametes (i.e., a larger and higher percentage of mature gametes (PMG)) of O. annularis for T1 vs. T3 ramets in May and T1 and T2 vs. T3 ramets in August. Similar values of PGS and MDE between gametes from T3 and T4 in both May and August were unexpected because a previous study had shown that the same ramets of T4 (with higher tissue thickness, chlorophyll a cm-2 and zooxanthellae density and lower mitotic index values) were less stressed than ramets of T3. Evaluating coral stress through reproduction can reveal more sensitive responses than other biological parameters; within reproductive metrics, PGS can be a better stress indicator than egg size. The presence of turf algae strongly impacted the development of gametes and egg size (e.g., PMG in ramets with FTA removal increased almost twofold in comparison with ramets surrounded by FTA in August), most likely exerting negative chronic effects in the long run due to the ubiquity and permanence of turf algae in the Caribbean. These algae can be considered a stressor that affects coral sexual reproduction. Although the effects of turf algae on O. annularis are apparently less severe than those of other stressors, the future of this species is uncertain because of the combined impacts of these effects, the decline of O. annularis populations and the almost

Health survey for 1014 radiological technologists was undertaken in 10 districts in Japan. Estimated radiation doses were based on work duration, the status of radiation protection, X-ray equipments to be used, and exposure conditions. Two hundred and eighty-three technologists aged between 45 and 59 were enrolled in this study. Exposure doses ranged from 2 cGy to 337 cGy. According to exposure doses of either 40 cGy, smoking habits, and drinking habits, the subjects were classified into 7 groups. Clinical laboratory data, in addition to systolic and diastolic blood pressures, were analyzed. In comparing the sole effect of irradiation with that of smoking or drinking, the degree of irradiation effect was less than the other two factors. Smoking had a higher synergistic action than irradiation and drinking. (N.K.)

For radiological technologists, it is very important to understand the principle of computed tomography (CT) and CT artifacts derived from mechanical and electrical failure. In this study, a CT system for educating radiological technologists was developed. The system consisted of a cone-beam CT scanner and educational software. The cone-beam CT scanner has a simple structure, using a micro-focus X-ray tube and an indirect-conversion flat panel detector. For the educational software, we developed various educational functions of image reconstruction and reconstruction parameters as well as CT artifacts. In the experiments, the capabilities of the system were evaluated using an acrylic phantom. We verified that the system produced the expected results. (author)

This is especially true in 2015 with regard to powerful new educational technologies. This article describes the challenges that 21st century educational technologists are, and will be, addressing as they undertake the effective integration of new technologies into K-12 educational systems and learning environments. The expanding Internet, ever more powerful mobile devices, and other innovations make the task of designing effective formal and informal learning challenging, especially in light of the high rate of change in these new technologies. While these technologies introduce many benefits, they are also causing serious threats to system security and personal privacy. Furthermore, as these technologies continue to evolve, ethical issues such as equal access to resources become imperative. Educational technologists must expand their forward-thinking leadership and planning competencies so as to ensure effective use of new technologies.

New marine commons along the Chilean coast – the management areas (MAs of Peñuelas and Chigualoco

Directory of Open Access Journals (Sweden)

2011-09-01

Full Text Available To halt degradation of benthic resources in Chile, management areas (MAs were set up under the Territorial Use Rights in Fisheries (TURFs framework in the late 1990s. Integrated into the global market, MAs have since expanded along the Chilean coast, involving thousands of small-scale artisanal fishers. This paper analyses how economic criteria relates to social and ecological performance of Chilean MAs, by applying TURFs, commons and co-management theory to two cases: MAs Peñuelas and Chigualoco. To collect and analyse data Participatory Rural Appraisal tools, interviews and official statistics and reports were used. Our results show that MAs’ economic benefits are connected to fluctuations on the global market. Adapting to changing world market prices then becomes paramount. TURFs’ main goal is ecological conservation, but achieving this seems to depend on meeting fishers’ livelihoods; failure to do so likely results in failure to meet conservation objectives. A serious weakness of the Chilean TURFs system is that it does not pay enough attention to fishers’ livelihoods or to the global market context. Furthermore, there is a strong relationship between good economic benefits and social sustainability. But irrespective of economic performance, fisher organizations have been empowered and gained increased resource control with the TURFs system. At policy level, a differentiated and more flexible system could be more suitable for existing heterogeneous MAs and their particular economic, social and ecological challenges. For improved economic sustainability and resource conservation, a system with multiple-species managing MAs could be promoted as well. Finally, to enhance theory of commons, co-management and TURFs, we argue for greater acknowledgement of TURFs’ social benefits in addition to economic assessments. More attention should also be paid to global market conditions of which MAs are dependent and in which they are embedded

Medical radiation workers were among the earliest occupational groups exposed to external ionizing radiation due to their administration of a range of medical diagnostic procedures and accounted for 7.4 million worldwide in 2008. Ionizing radiation is the confirmed human carcinogen for most organ sites. The aims of the study is to evaluate the association between occupational practices including radiation exposure and thyroid cancer risk among radiologic technologists. We found no significant association between the risk of thyroid cancer and the majority of work practices among diagnostic radiation technologists in general. However workers performing fluoroscopy and interventional procedures showed increased risks although the lack of a clear exposure– response gradient makes it difficult to draw clear conclusions. Future studies with larger sample size and detailed work practices implementation are needed to clarify the role of occupational radiation work in thyroid cancer carcinogenesis.

The efficacy of radiation therapy is to eradicate the tumor while preserving the integrity of normal tissues. Technological advances have allowed to develop techniques capable of modulating doses delivered to the target volume, providing more effective treatments. However, the operational complexity of these techniques makes the benefits offered are directly proportional to the chances of occurrences of serious errors. The objective of this work is to analyze the steps performed by the technician/technologist in Intensity Modulated Radiotherapy (IMRT), to detect possible errors in order to determine ways to mitigate them. After literature regarding errors in the radiation therapy, a prospective analysis was performed in the first half of 2012 in a radiation clinic located in the city of Rio de Janeiro, in which 11 technicians/technologists contributed to the survey data analysis. The method of risk analysis Failure Mode and Effects Analysis was used for prospective analysis of accidents/incidents, with respect to a qualitative assessment . The method allowed mapping 16 steps performed by technicians/technologists in the treatments with IMRT, identifying possible failures and their causes allowing to find ways to avoid possible errors. This analysis helped to confirm that the qualification and continuing education of technicians/technologists, allied to implement quality assurance programs and a computerized management can make a tool capable of IMRT to achieve the greatest challenge of radiotherapy.

From 2011 to 2017, the combination of record low precipitation and extreme warm temperatures resulted in the most severe drought in California's written history. In April 2015, Governor Jerry Brown issued an executive order mandating a statewide 25% reduction in potable urban water usage. Under such circumstances, outdoor watering is an obvious target for restriction, because it can account for a large fraction of total domestic water usage, up to 50% in the arid southwest [Syme et. al 2004, Cameron et. al 2012]. In this study we analyzed one such effort, in which the Irvine Ranch Water District (IRWD) in Orange County (California) offered a financial incentive through a turf rebate program to encourage Irvine residents to replace turf grass with drought tolerant landscaping. We focused specifically on the number of residents who applied to the turf rebate program. Our hypothesis was that the observed application rate (number of applicants per month) is influenced by a combination of (a) financial incentives issued by IRWD, (b) drought awareness, and (c) the fraction of neighbors that have already applied to the program (a phenomenon that can be described quantitatively through models of social contagion or social diffusion [Karsai et. al 2014]). Our preliminary results indicate that applications to the program occurred in geographic "hot spots", consistent with the idea that early adopters may have influenced neighbors to retrofit their lawns. We are currently evaluating the geographic, demographic, and temporal drivers that influence the rate of spontaneous adoption, the rate of adoption under influence, and the total size of the susceptible population. Overall, our goal is to identify the key factors that contribute to early rapid uptake of conservation behavior, and the rapid diffusion of that behavior through the community.

In order to study the occurrence of symptoms of musculoskeletal disorders of radio-technologists employed at metropolitan general hospitals and the factors that influence such occurrence, standardized questionnaire by NIOSH that was modified and supplemented to be suitable for conditions in Korea was used. Answers collected from 143 radio-technologists in two weeks from June 13, 2007 were analyzed and the results are as follows. Factor that influence symptoms of musculoskeletal disorders by area were analyzed through multiple logistic regression analysis and the results found that in the neck area, risk increased as the burdening work category 2(Korea ministry of labor)(OR=3.94) and burdening work category 9(Korea ministry of labor)(OR=4.72) increased. In the shoulder region, risk increased as burdening work category 2(Korea ministry of labor)(OR=5.36), burdening work category 7(Korea ministry of labor)(OR=3.90), and burdening work category 9 (Korea ministry of labor)(OR=5.76) increased. In the arm/hand/wrist regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=6.91), and burdening work category 9 (Korea ministry of labor)(OR=3.76) increased. In the lower back region, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.06), and burdening work category 8 (Korea ministry of labor)(OR=8.14) increased. In the leg/knees/foot regions, risk increased as burdening work category 2 (Korea ministry of labor) (OR=3.63), and burdening work category 9 (Korea ministry of labor)(OR=2.96) increased. Conclusively, in factors that influence musculoskeletal disorder symptoms in radio-technologists, influence of subjective health conditions, total work experience, experience in current division, and burdening work category 2, 7, 8, and 9 (Korea ministry of labor) were most significant. Therefore, for preventive management, in addition to ergonomic and educational intervention for correcting improper posture during work, efforts for

We are developing a mammographic ontology to share knowledge of the mammographic domain for radiologic technologists, with the aim of improving mammographic techniques. As a first step in constructing the ontology, we used mammography reference books to establish mammographic terminology for identifying currently available knowledge. This study proceeded in three steps: (1) determination of the domain and scope of the terminology, (2) lexical extraction, and (3) construction of hierarchical structures. We extracted terms mainly from three reference books and constructed the hierarchical structures manually. We compared features of the terms extracted from the three reference books. We constructed a terminology consisting of 440 subclasses grouped into 19 top-level classes: anatomic entity, image quality factor, findings, material, risk, breast, histological classification of breast tumors, role, foreign body, mammographic technique, physics, purpose of mammography examination, explanation of mammography examination, image development, abbreviation, quality control, equipment, interpretation, and evaluation of clinical imaging. The number of terms that occurred in the subclasses varied depending on which reference book was used. We developed a terminology of mammographic techniques for radiologic technologists consisting of 440 terms.

International Stability. The Responsibility of the Scientist and Technologist

International Nuclear Information System (INIS)

Broda, E.

1983-01-01

Scientists and technologists ('technical experts') bear heavy responsibility for the explosive world situation where the further existence of civilization is threatened. Without their initiatives and their efforts the weapons of mass annihilation would not have been invented and developed. The essential features of nuclear warfare are explained. 25-40% of the world force of technical experts may be on war work now. Whatever justification for their work they see, they are tied to it, as quitting would mean loss of income, possibilities for professional career, status and prestige. On the other hand, many scientists, including Bohr, Joliot, Pauling, Einstein and Russell, have done invaluable work in informing, warning, educating and mobilizing the public against the danger of a nuclear war. In the present desperate situation the support of the largest possible number of technical experts for such activities ought to be enlisted. In this respect engineers and technologists could follow the example of medical doctors. Moreover, owing to their familiarity with criteria for stability in material systems engineers could make constructive proposals for the improvement of stability in international relations. (author)

The fate of urea applied to Kentucky bluegrass (Poa pratensis L.) turf was studied over a 2-yr period using a combination of intact monolith lysimeters and small plots. Soil type was a Marlette fine sandy loam (fine-loamy mixed mesic Glossoboric Hapludalfs). Urea was applied at a rate of 196 kg N ha-1 yr-1 in five equal applications of 39.2 kg N ha-1, using two application schedules. Treatments were fertilized at approximately 38-d intervals with the 'Spring' treatment fertilized from late April through late September and the 'Fall' treatment from early June through early November. In 1991 only, the April and November applications used 15N-labeled urea (LFN). For the Spring treatment, 31% of LFN was recovered from thatch at 18 DAT. This value remained constant for the next year, then gradually declined to 20% after 2 yr. Only 8% of the LFN was recovered from soil at 18 DAT and increased to only 20% 2 yr after application. Approximately 35% of the LFN was harvested in clippings over 2 yr. Through May 1993 (748 DAT), LFN in leachate totaled 0.18% of the amount applied. For the Fall treatment, 62% of the LFN was recovered from thatch d 18 DAT. This value declined to 35% by the following June. LFN in soil increased from 12% to 25% over 2 yr. Approximately 38% of the LFN was harvested in clippings over 2 yr. Total leachate LFN recovery was 0.23% over the 2-yr period. Total recovery of LFN was 64 and 81% for the Spring and Fall treatments, respectively, suggesting volatile losses of N. Whether the N was applied in the spring or late fall, rapid uptake and immobilization of the LFN resulted. A maximum of 25% of applied LFN was recovered in the soil from either application timing at any time over the 2 yr of the experiment. A well-maintained turf intercepts and immobilizes LFN quickly making leaching an unlikely avenue of N loss from a turf system

This technical innovation describes the development of a novel device to aid technologists in reducing exposure variation and repeat imaging in computed and digital radiography. The device consists of a color video and depth camera in combination with proprietary software and user interface. A monitor in the x-ray control room displays the position of the patient in real time with respect to automatic exposure control chambers and image receptor area. The thickness of the body part of interest is automatically displayed along with a motion indicator for the examined body part. The aim is to provide an automatic measurement of patient thickness to set the x-ray technique and to assist the technologist in detecting errors in positioning and motion before the patient is exposed. The device has the potential to reduce the incidence of repeat imaging by addressing problems technologists encounter daily during the acquisition of radiographs. (orig.)

In this study, we assessed the community and educational needs for sleep technologists by surveying program directors of nationally accredited polysomnography, electroneurodiagnostic technology, and respiratory care educational programs. Currently, little is known about our educational capacity and the need for advanced degrees for sleep medicine technical support. A questionnaire was developed about current and future community and educational needs for sleep technologists. The questionnaire was sent to directors of CAAHEP-accredited polysomnography and electroneurodiagnostic technology programs (associate degree and certificate programs), and directors of CoARC-accredited respiratory therapy associate degree and bachelor degree programs (n = 358). Qualitative and quantitative data were collected via an internet survey tool. Data analysis was conducted with the IBM SPSS statistical package and included calculating means and standard deviations of the frequency of responses. Qualitative data was analyzed and classified based on emerging themes. One hundred seven of 408 program directors completed the survey. Seventy-four percent agreed that demand for qualified sleep technologists will increase, yet 50% of those surveyed believe there are not enough educational programs to meet the demand. Seventy-eight percent of those surveyed agreed that the educational requirements for sleep technologists will soon increase; 79% of those surveyed believe sleep centers have a need for technologists with advanced training or specialization. Our study shows educators of associate and certificate degree programs believe there is a need for a bachelor's degree in sleep science and technology.

Japanese radiological technologists occupationally have chances of receiving low doses of ionizing radiation. A cohort study was started on them in 1981, since knowledge of the mortality and health of this population is pertinent to the evaluation of the risk from low-level exposure to radiation. A sampling of 2028 Japanese radiological technologists born before 1933 was followed from 1969 to 1982. All deaths were confirmed by checking copies of family registers and the causes were obtained from death certificates. The deaths observed within this group were compared with the expected number of deaths from major causes as estimated using the Japanese life table of 1975. The number of deaths from all causes, 131, was less than the expected 182.39, a difference that is statistically significant at the 1% level. The observed number of deaths from all malignant neoplasms, 51, was slightly larger than that of the expected 48.94, although the difference was not statistically significant. However, there was a significant excess of observed deaths from brain tumour and malignant neoplasms of male urogenital organs in comparison with expected deaths. Deaths from anaemia also significantly exceeded the expected level. The relationship between dose level and cause of death as adjusted by age at death and first year of employment was investigated using contingency table analysis. Accumulated occupational doses were estimated for 599 of the population of 2028. The relative risk of mortality ratios for all causes of death and cancer of all sites in four dose categories, <50, 50-74, 75-99 and 100+ rad, increased with dose but the statistical tests did not show any significant association. Observation and analysis should be continued to check our present findings further and obtain more complete data. (author)

Technologist assessment of abnormalities in mammography

International Nuclear Information System (INIS)

Cheesman, A.

2006-01-01

Clinical images must meet the needs of the radiologist in order to serve the patient well. Learning to fully appreciate and assess the range of potentially pathological concerns is an important part of the role of the mammographer within the breast imaging team: being sure of a complete study that serves the purpose for the radiologist goes beyond pure technical appreciation. It now requires some clinical knowledge in order to ensure the area of concern is appropriately imaged, clearly seen and readily characterized by the radiologist. The technologist's role in ensuring appropriate imaging to clarify the extent of potential disease becomes an integral part of the criteria for excellence. Application of our basic analytical skills to our patient history and clinical images should now be an expectation of the mammographic technologist. Assessing and demonstrating clearly an area of concern on our images is a long way from diagnosing disease. What is missed or obscured on our clinical images is not analyzed by the radiologist. Therefore it is essential that we recognize a possible concern and know how to demonstrate it clearly. To recognize what is potentially a concern, it helps to know a little about where and how pathology within the breast develops. There are three basic areas of concern when checking our images, clinical assessment, calcifications and masses. The mammographer within today's modern team oriented department must have the advanced positioning and clinical skills to ensure the area of concern is appropriately imaged, clearly seen and able to be characterized by the radiologist. To properly assess and demonstrate potential problems for our medical partner, the radiologist, we must understand well the three areas of clinical and pathological change that exposes early breast cancer.

2018-02-02

The proliferation of pediatric urgent care centers has increased the need for diagnostic imaging support, but the impact of employing radiology technologists at these centers is not known. The purpose of this study was to evaluate radiographic impact and quality at urgent care centers with and without radiology technologists. A retrospective case-control study was conducted comparing 235 radiographic examinations (study) performed without and 83 examinations (control) performed with a radiology technologist at the authors' pediatric urgent care centers. Studies were evaluated for quality using a five-point, Likert-type scale (1 = poor, 5 = best) regarding field of view, presentation, and orthogonal view orientation. Studies were also evaluated for the incidence of positive results, need for repeat imaging, and discrepancies between initial study and follow-up. Imaging quality comparisons between study and control groups were statistically different for field of view (3.98 versus 4.29, P = .014), presentation (4.39 versus 4.51, P = .045), and orthogonal view orientation (4.45 versus 4.69, P = .033). The incidence of repeat imaging was similar (4.7% versus 2.4%, P = 0.526), as well as the discrepancy rates (3.4 versus 2.4%, P = 1.00). The incidence of abnormal radiographic findings for the study and control groups was similar (40.9% versus 34.9%, P = .363). Radiography is an important triage tool at pediatric urgent care centers. It is imperative to have optimal radiographic imaging for accurate diagnosis, and imaging quality is improved when radiology technologists are available. If not feasible or cost prohibitive, it is important that physicians be given training opportunities to bridge the quality gap when using radiographic equipment and exposing children to radiation.

Microsystems technologist workforce development capacity and challenges in Central New Mexico.

Energy Technology Data Exchange (ETDEWEB)

Osborn, Thor D.

2008-04-01

Sandia National Laboratories has made major investments in microsystems-related infrastructure and research staff development over the past two decades, culminating most recently in the MESA project. These investment decisions have been made based in part upon the necessity for highly reliable, secure, and for some purposes, radiation-hardened devices and subsystems for safety and sustainability of the United States nuclear arsenal and other national security applications. SNL's microsystems development and fabrication capabilities are located almost entirely within its New Mexico site, rendering their effectiveness somewhat dependent on the depth and breadth of the local microsystems workforce. Consequently, the status and development capacity of this workforce has been seen as a key personnel readiness issue in relation to the maintenance of SNL's microsystems capabilities. For this reason SNL has supported the instantiation and development of the Southwest Center for Microsystems Education, an Advanced Technology Education center funded primarily by the National Science Foundation, in order to foster the development of local training capacity for microsystems technologists. Although the SCME and the associated Manufacturing Technology program at Central New Mexico Community College have developed an effective curriculum and graduated several highly capable microsystems technologists, the future of both the center and the degree program remain uncertain due to insufficient student enrollment. The central region of New Mexico has become home to many microsystems-oriented commercial firms. As the demands of those firms for technologists evolve, SNL may face staffing problems in the future, especially if local training capacity is lost.

Our aim in this study was to evaluate the effect of the radiologist, technologist, and other examination-related factors on the frequency of recommendations for additional imaging (RAI) during sonographic (US) interpretation. We retrospectively reviewed 719 US reports from a single academic medical center for the presence of RAI. All studies had been interpreted by one of three abdominal radiologists. Examinations were performed at an outpatient radiology facility with no onsite radiologist (n = 299) or at an inpatient emergency department or hospital-based outpatient setting that had an onsite radiologist (n = 420). Possible associations between the frequency of RAI and the presence of an onsite radiologist, location of the examination, body part or region imaged, patient age, technologist performing the exam, and radiologist reading the exam were evaluated. There were significant differences between each pair of radiologists in terms of overall frequency of RAI (p technologists (13.6%-40.0%, p = 0.03). However, other factors such as patient age, patient sex, US unit, patient location, and radiologist location were not associated with the frequency of RAI (p = 0.15-0.93). The individual radiologist and technologist influenced the frequency of RAI for US examinations, whereas other examination-related factors did not. The observed substantial variability in RAI between radiologists and technologists warrants further study, with consideration of strategies to optimize RAI within US reports. © 2015 Wiley Periodicals, Inc.

Role of the technologist in the lymphoscintigraphy and the identification of sentinel node in malignant skin melanoma

International Nuclear Information System (INIS)

Barbier, D.

2002-01-01

The biopsy of the first tumor-draining lymph node (sentinel node) is bound to become the procedure of choice in regional staging of skin melanoma patients. In our department, we do successively: lymphoscintigraphy; identification of sentinel node by γ probe before surgery; identification during surgery of sentinel node with γ probe. During those different steps, the technologist has an important role. The different steps of the technologist's work are: Preparation of radiopharmaceutical Tc 99m Nanocolloides (Nanocis Cis Bio Int); Control of radio chemical purity(RCP) by thin-layer chromatography (TLC); Programming of acquisition protocol on the γ camera; Acquisition of dynamic and static images; Identification percutaneous of the sentinel node with the γ probe and Co 57 pencil; Processing of scintigraphic images; At least identification with surgeon of the sentinel node. After excision of the lymph node, we have to verify the disappearing of radioactivity. Those steps will be illustrated by different clinical cases. Conclusion: Sentinel node identification is: New useful technique for patient: not very much invasive; screening of patients with high risk factors; great parameters of prognosis; Interest for technologist: narrow collaboration with nuclearist and surgeon; psychological role close to the patient; various competency of technologist; diagnostic and therapeutic participations

A computer program was created to train technologists to perform chest X-rays in crying infants at maximum inspiration. Videos of 4 children were used. Using a computer program, the moment of deepest inspiration was determined in the video in the single frame view. During the normal running video, 14 technologists (3 with significant experience, 3 with little experience and 8 with very little experience in pediatric radiography) simulated a chest radiograph by pushing a button. The computer program stopped the video and the period of time to the optimal moment for a chest x-ray was calculated. Every technologist simulated 10 chest X-rays in each of the 4 video clips. The technologists then trained themselves to perform chest X-rays at optimal inspiration like playing a computer game. After training, the test was repeated. Changes were evaluated by t-test for unpaired samples (level of significance p < 0.05). Although the differences improved in all children, minimal deviation from the optimal moment for taking an X-ray at inspiration occurred in the periodically crying child (0.21 sec before and 0.13 sec after training). In a non-periodically crying infant, the largest differences were shown. The values improved significantly from 0.29 sec to 0.22 sec. The group with substantial experience in pediatric radiology improved significantly from 0.22 sec to 0.15 sec. The group with very little experience in pediatric radiology showed worse results (improvement from 0.29 sec to 0.21 sec). (orig.)

The widely-used Tif-series of turf bermudagrasses - Tifgreen, Tifway, and Tifdwarf - are vegetatively propagated sterile triploids that cannot be improved by conventional breeding methods. Dormant stolons, washed free of soil and cut into one-or two-node sections were treated with varying dosages of EMS (ethyl methane sulfonate) and gamma irradiation ranging from 7 to 12 kR. EMS failed to produce noticeable variants but gamma irradiation from a Cobalt 60 source created 158 mutants. These mutants differed in many characters such as leaf size, hairiness, stem diameter, internode length, basic plant color, herbicide tolerance, spreading rate, and nematode resistance. Attempts to improve the winterhardiness of tetraploid sterile Coastcross-1 forage bermudagrass by exposing over 1,400,000 sprigs (vegetative stems) to 7 kR of gamma rays gave chlorophyll deficient mutants but progress in increasing winterhardiness has not been established.

Ionizing radiations are used in areas such as health, industry and safety, not only in the private sector, but also in the public. Thus, it is necessary the radiological protection, a set of studies and practices that increases the safety in these applications, where the professional involved is the technologist in radiology. The objective was to analyze the contents effectively required by the Brazilian public agencies in their competitions for radiology technologist, regarding the area of radiological protection, identifying their profile of requirement. It consisted of three stages: first, a survey of all the public competitions already carried out in the country up to the end of 2016, that requested a diploma of graduation in Technology in Radiology; second, all the specific questions were collected and grouped in an electronic text file; third, issues involving radiological protection were segregated, using as reference the 2017 edition of the National Nuclear Energy Commission's General Proof of Radioprotection Supervision. The results showed that almost 40% of the competition questions were about radiation protection. From this sampling, the topics most covered were: radiological safety (36%), fundamentals of atomic and nuclear physics (24%) and biological effects of radiation (16%). It is concluded that the competitions for radiologist technologist have the profile of concentration of exigency in radiological safety, fundamentals of atomic and nuclear physics and biological effects of the radiations

In this study a group of experts and clinical radiological technologists were surveyed to evaluate the clinical importance of current subjects in the radiological sciences. For the data collection and analysis, an open-ended questionnaire was distributed to the group of experts, and a multiple choice questionnaire was distributed to radiological technologists. Subjects were classified into 9 groups for analysis of the importance of subjects, and in regard to the questionnaire design for measurement of variables, departments and type of hospital were set up as independent variables, and the 9 groups of subjects were set up as dependent variables. As a result, clinical radiological technologists perceived Diagnostic Imaging Technology and practical courses, including general radiography, CT and MRI, as the most clinically necessary subjects, and the group of experts placed most weight on basic courses for the major. The result of this study suggests that the curriculum should be revised in a way that combines theory and practice in order to foster radiological technologists capable of adapting to the rapidly changing healthcare environment.

Current medical care is subdivided according to medical advances, and sophistication and new techniques are necessary. In this setting, doctors and nurses have been explaining to and consulting patients about their medical examinations; however, in recent years, medical technologists have performed these duties at the start of the team's medical care. Therefore, we think it is possible for patients to receive clear and convincing explanations. Most patients cannot understand their examination data, which are written using numbers and charts, etc. Recently, the Nagano Medical Technologist Society has been developing technologists who could explain examination results to patients. This development training included hospitality and communication. The certificate of completion will be issued in March when the program starts.

Modern CT is a powerful yet increasingly complex technology that continues to rapidly evolve; optimal clinical implementation as well as appropriate quality management and improvement in CT are challenging but attainable. This article outlines the organizational structure on which a CT quality management and improvement program can be built, followed by a discussion of common as well as pediatric-specific challenges. Organizational elements of a CT quality management and improvement program include the formulation of clear objectives; definition of the roles and responsibilities of key personnel; implementation of a technologist training, coaching and feedback program; and use of an efficient and accurate monitoring system. Key personnel and roles include a radiologist as the CT director, a qualified CT medical physicist, as well as technologists with specific responsibilities and adequate time dedicated to operation management, CT protocol management and CT technologist education. Common challenges in managing a clinical CT operation are related to the complexity of newly introduced technology, of training and communication and of performance monitoring. Challenges specific to pediatric patients include the importance of including patient size in protocol and dose considerations, a lower tolerance for error in these patients, and a smaller sample size from which to learn and improve.

Phosphorus enrichment of surface water is a concern in many urban watersheds. A 3-yr study on a silt loam soil with 5% slope and high soil test P (27 mg kg(-1) Bray P1) was conducted to evaluate P fertilization and clipping management effects on P runoff from turfgrass (Poa pratensis L.) under frozen and nonfrozen conditions. Four fertilizer treatments were compared: (i) no fertilizer, (ii) nitrogen (N)+potassium (K)+0xP, (iii) N+K+1xP, and (iv) N+K+3xP. Phosphorus rates were 21.3 and 63.9 kg ha(-1) yr(-1) the first year and 7.1 and 21.3 kg ha(-1) yr(-1) the following 2 yr. Each fertilizer treatment was evaluated with clippings removed or clippings recycled back to the turf. In the first year, P runoff increased with increasing P rate and P losses were greater in runoff from frozen than nonfrozen soil. In year 2, total P runoff from the no fertilizer treatment was greater than from treatments receiving fertilizer. This was because reduced turf quality resulted in greater runoff depth from the no fertilizer treatment. In year 3, total P runoff from frozen soil and cumulative total P runoff increased with increasing P rate. Clipping management was not an important factor in any year, indicating that returning clippings does not significantly increase P runoff from turf. In the presence of N and K, P fertilization did not improve turf growth or quality in any year. Phosphorus runoff can be reduced by not applying P to high testing soils and avoiding fall applications when P is needed.

Job satisfaction is very important for adequate manpower management in the medical field. To study job satisfaction among the radiologic technologists, 344 cases were reviewed in five university hospitals and one general hospital. Self-administered questionnaire was used to study their socioeconomic characteristics, working conditions, job satisfaction, and the factors affecting there job satisfaction. The results were as follows : 1. There was statistically significant difference in job satisfaction according to the their department of employment, position, and hospital characteristics. 2. The group that was satisfied with their salary had a higher job satisfaction score, whereas others who were not satisfied ranked lower. 3. The positive answering group on the ability and job recognition ranked higher score on the job satisfaction than the negative answering group. 4. The group that was in good relationship with their superiors and co-workers scored higher on job satisfaction. From the above results, the job satisfaction was high for the group with positive thinking and reply, but the intentin to change their job was low. Considering the fact that these results represent only 6 hospitals from limited arease, therefore, necessary to include more medical facilities nationwide, especially small-medium sized clinics or hospitals where the difficulty with high turnover rate of employment is expected, to study further various factors involving job satisfaction in the future

Image Gently: Challenges for radiologic technologists when performing digital radiography in children

Goske, Marilyn J.; Smith, Susan N.; Charkot, Ellen; Herrmann, Tracy; John, Susan D.; Mills, Thalia T.; Morrison, Gregory

2011-01-01

The development of digital radiography (DR) has provided numerous benefits for pediatric imaging, including the ability to post-process images and to make images immediately available for access by care providers. However, DR presents several significant challenges for the radiologic technologists who are responsible for operating the equipment and producing high-quality images in children. This paper discusses those challenges, including lack of standardization among vendors, particularly with regard to the exposure indicator; lack of pediatric-specific educational materials and pediatric techniques; the need for manual technique instead of the use of automatic exposure control in smaller children; and complications related to field size, collimation and shielding in small children. Specific actions and design modifications that might facilitate the effective management of these challenges will be also described. The implementation of measures to promote the production of optimal images while minimizing radiation exposure requires cooperation and communication among imaging professionals, manufacturers and regulatory agencies.

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.

[Future roles of clinical laboratories and clinical laboratory technologists in university hospitals].

Science.gov (United States)

Yokota, Hiromitsu; Yatomi, Yutaka

2013-08-01

Clinical laboratories in university hospitals should be operated with a good balance of medical practice, education, research, and management. The role of a clinical laboratory is to promptly provide highly reliable laboratory data to satisfy the needs of clinicians involved in medical practice and health maintenance of patients. Improvement and maintenance of the quality of the laboratory staff and environment are essential to achieve this goal. In order to implement these requirements efficiently, an appropriate quality management system should be introduced and established, and evaluated objectively by a third party (e.g. by obtaining ISO 15189 certification). ISO 15189 is an international standard regarding the quality and competence of clinical laboratories, and specifies a review of the efficient operational system and technical requirements such as competence in implementing practical tests and calibration. This means the results of laboratory tests reported by accredited laboratories withstand any international evaluation, which is very important to assure the future importance of the existence and management of clinical laboratories as well as internationalization of medical practice. "Education" and "research" have important implications in addition to "medical practice" and "management", as the roles that clinical laboratories should play in university hospitals. University hospital laboratories should be operated by keeping these four factors in good balance. Why are "education" and "research" required in addition to "medical practice" services? If individual clinical laboratory technologists can provide an appropriate response to this question, the importance of the existence of clinical laboratories would be reinforced, without being compromised.

Technologists working in nuclear medicine (NM) are exposed to higher radiation doses than most other occupationally exposed populations. The aim of this study was to estimate the risk of cancer in NM technologists in relation to work history, procedures performed and radioprotection practices. From the US Radiologic Technologists cohort study, 72 755 radiologic technologists who completed a 2003-2005 questionnaire were followed for cancer mortality through 31 December 2012 and for cancer incidence through completion of a questionnaire in 2012-2013. Multivariable-adjusted models were used to estimate HRs for total cancer incidence and mortality by history of ever performing NM procedures and frequency of performing specific diagnostic or therapeutic NM procedures and associated radiation protection measures by decade. During follow-up (mean=7.5 years), 960 incident cancers and 425 cancer deaths were reported among the 22 360 technologists who worked with NM procedures. We observed no increased risk of cancer incidence (HR 0.96, 95% CI 0.89 to 1.04) or death (HR 1.05, 95% CI 0.93 to 1.19) among workers who ever performed NM procedures. HRs for cancer incidence but not mortality were higher for technologists who began performing therapeutic procedures in 1960 and later compared with the 1950s. Frequency of performing diagnostic or therapeutic NM procedures and use of radioprotection measures were not consistently associated with cancer risk. No clear associations were observed for specific cancers, but results were based on small numbers. Cancer incidence and mortality were not associated with NM work history practices, including greater frequency of procedures performed. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The purpose of this study was to determine the relative cost reductions within different staffing models for continuous video-electroencephalography (cvEEG) service by introducing a template system for 10/20 lead application. We compared six staffing models using decision tree modeling based on historical service line utilization data from the cvEEG service at our center. Templates were integrated into technologist-based service lines in six different ways. The six models studied were templates for all studies, templates for intensive care unit (ICU) studies, templates for on-call studies, templates for studies of ≤ 24-hour duration, technologists for on-call studies, and technologists for all studies. Cost was linearly related to the study volume for all models with the "templates for all" model incurring the lowest cost. The "technologists for all" model carried the greatest cost. Direct cost comparison shows that any introduction of templates results in cost savings, with the templates being used for patients located in the ICU being the second most cost efficient and the most practical of the combined models to implement. Cost difference between the highest and lowest cost models under the base case produced an annual estimated savings of $267,574. Implementation of the ICU template model at our institution under base case conditions would result in a $205,230 savings over our current "technologist for all" model. Any implementation of templates into a technologist-based cvEEG service line results in cost savings, with the most significant annual savings coming from using the templates for all studies, but the most practical implementation approach with the second highest cost reduction being the template used in the ICU. The lowered costs determined in this work suggest that a template-based cvEEG service could be supported at smaller centers with significantly reduced costs and could allow for broader use of cvEEG patient monitoring.

Late radiation effects of low doses from occupational exposure. Antibodies to cytomegalovirus, Epstein-Barr virus and human T cell lymphotropic virus type 1 in radiological technologists

To elucidate the effects of long-term exposure to low dose irradiation, serostatus of antibodies to cytomegalovirus (CMV), Epstein-Barr virus (EBV) and human T cell lymphotropic virus type 1 (HTLV-1) was determined in 99 radiological technologists and 96 healthy volunteers. Abnormal seropositivity rate for CMV was significantly higher in technologists working for 15 years or more than in those working for less than 15 years. For the same age group, however, there was no significant difference between technologists and controls. Seropositivity rates for EBV-viral capsid antigen (VSA)/IgG and early antigen (EA)/IgG were significantly higher in technologists working for 15 years or more than in the age-matched control group. In the group of technologists exposed to 0.3 Sv or more, seropositivity rates of these antibodies were significantly higher than in those exposed to less than 0.3 Sv. However, there was no correlation between exposure doses and both EBV-associated nuclear antigen antibody and HTLV-1 antibody. Few technologists seronegative for CMV antibody had seropositive antibodies of EBV-VCA/IgG and EA/IgG. For technologists seropositive for CMV antibody, 31% and 54% were seropositive for EBV-VCA/IgG and EA/IgG antibodies, respectively. (Namekawa, K).

Standing at the crossroads: Identity and recognition of the Applied Science Technologist in British Columbia

Science.gov (United States)

Roemer, Thomas

Modern technical education in British Columbia has been affected by two societal trends: in industry, engineering technology evolved as a discipline to bridge the increasing chasm between the process-oriented skill sets of tradespersons/technicians, and the declarative knowledge focus of engineering; in education, the provincial college and institute system was created to address the need for a new post-secondary credential situated between trades certificates and university degrees. The Applied Science Technologist arguably forms the intersection of these two concepts. Almost forty years after its inception, it is timely to ask if the original model has matured into a distinct occupational category in industry, education, and in the public mind. The thesis proposes three environments, the Formative, Market and Public Domain, respectively. Interviews, surveys and personal experience afforded insights into the dynamics of these domains with respect to a fledgling occupational category, while the socio-philosophical concepts of culture, habitus and social imaginary provide the tools to interpret the findings. The thesis postulates that an emerging occupational category will not only challenge existing cultures and habitus, but that over time it will influence the imaginaries of each domain and society as a whole. Ultimately, the occupational category will be truly successful only when the general public is able to distinguish it from related disciplines. Charles Taylor's writings on multiculturalism are used to discuss identity and recognition of the Applied Science Technologist in each domain while Pierre Bourdieu's perspectives on the existence of habitus and self-proliferating elites form the framework to examine the relationships between technologists and engineers. Taylor's theory of multiple concurrent social imaginaries guides the comparison of divergent expectations among academic, career and vocational instructors at British Columbia's colleges. The thesis

Thermocompression bonding of vertically aligned carbon nanotube turfs to metalized substrates

International Nuclear Information System (INIS)

Johnson, R D; Bahr, D F; Richards, C D; Richards, R F; McClain, D; Green, J; Jiao, J

2009-01-01

Vertically aligned carbon nanotube turfs (VACNTs), consisting of entwined, nominally vertical carbon nanotubes, are being proposed for use as electrical and thermal contact materials. Issues in their implementation include high contact resistance, the van der Waals interactions of carbon nanotubes, and a low temperature limit during processing. One route for circumventing the 750 deg. C temperatures required for VACNT growth using chemical vapor deposition is for the VACNTs to be grown separately, and then transferred to the device. A method of mechanical transfer, using thermocompression bonding, has been developed, allowing dry mechanical transfer of the VACNTs at 150 deg. C. This method can be used for the construction of both a thermal switch or a permanent conducting channel. The conductivity of the bonded structure is shown to be independent of the imposed strain, up to strains in excess of 100%.

Self-completed questionnaires were used to obtain information on exposures and otherb factors necessary to evaluated disease risks. Although reliability of lifetime sun exposure of U.S. radiologic technologists and life-style factors, medical exams, and disease history of Korean nuclear power plants workers (2) were reported, few studies have evaluated the reliability of information obtained on radiation-related work in epidemiologic investigations. The aims of the study is to assess reliability of self-reported questionnaire for occupational radiation work in the radiologic technologists in Korea. Overall agreement and kappa regarding radiation work procedure, work practice, and work history were similar to those generally found for factors typically used in epidemiologic studies such as smoking (98% and 0.95) and alcohol consumption (88% and 0.67), and higher than physical activity (76% and 0.51).

Health concerns over the composition of the in fill material used to construct artificial turf pitches (e.g., for soccer and rugby), raised the need to develop a specific procedure to assess the risks of human exposure to pollutants that may be released by these materials. The aim of this paper was to develop and implement a survey protocol to assess exposure of artificial turf pitches users (e.g., coaches and maintenance personnel) through environmental and biological monitoring of toxic and carcinogenic substances contained in some types of in fill materials for artificial turf pitches. The exposure was assessed by personal and environmental sampling of hazardous substances - particularly of benzene, toluene, xylene (BTX), polycyclic aromatic hydrocarbons (PAHs) and heavy metals (lead, cadmium, chromium, tin and zinc) - for comparison with the occupational exposure limit values as per the Italian regulations and the lists of the American Conference of Industrial Governmental Hygienists (ACGIH). In addition, biological monitoring was performed for the quantitative and qualitative determination of the exposure bio markers of the substances of interest in potentially exposed individuals and in control group. Environmental sampling was performed on an outdoor, artificial turf soccer pitch in a sports facility in Rome characterized by recycled in fill material (rubber granules from recycled tyres, without any further processing); suction pumps were used as environmental samplers to collect the samples (located in areas of the soccer pitch deemed representative of exposure conditions) and personal samplers (in this latter case exclusively for monitoring PAHs) worn by the coaches during training sessions. For the various substances the following sampling systems were used: vials for BTX (benzene, toluene, and xylene), filters for metals and combined systems (filter plus vial) for the PAHs. The extracts were then analyzed by various instrumental techniques such as gas

Skills and knowledge regarding many different types of test are required for medical technologists (MTs) to provide accurate information to help doctors and other medical specialists. In order to become an efficient MT, specialized training programs are required. Certification in specialized areas of clinical laboratory sciences or a doctoral degree in medical sciences may help MTs to realize career advancement, a higher earning potential, and expand the options in their career. However, most young MTs in national university hospitals are employed as part-time workers on a three-year contract, which is too short to obtain certifications or a doctoral degree. We have to leave the hospital without expanding our future. We need to take control of our own development in order to enhance our employability within the period. As teaching and training hospitals, national university hospitals in Japan are facing a difficult dilemma in nurturing MTs. I hope, as a novice medical technologist, that at least university hospitals in Japan create an appropriate workplace environment for novice MTs.

Radiological Technologists deals with the life of a person which means professional competency is essential for the job. Nevertheless, there have been no studies in Korea that identified the job competence of radiologists. In order to define the core job competencies of Korean radiologists and to present the factor models, 147 questionnaires on job competency of radiology were analyzed using 'PASW Statistics Version 18.0' and 'AMOS Version 18.0'. The valid model consisted of five core job competencies ('Patient management', 'Health and safety', 'Operation of equipment', 'Procedures and management') and 17 sub – competencies. As a result of the factor analysis, the RMSEA value was 0.1 and the CFI, and TLI values were close to 0.9 in the measurement model of the five core job competencies. The validity analysis showed that the mean variance extraction was 0.5 or more and the conceptual reliability value was 0.7 or more , And there was a high correlation between subordinate competencies included in each subordinate competencies. The results of this study are expected to provide specific information necessary for the training and management of human resources centered on competence by clearly showing the job competence required for radiologists in Korea's health environment

The applications of radiation to the medical field are increasing steadily, along with advances in radiation technology and development of new medical equipment. Medical applications of radiation differ from applications in other fields, because the patient is exposed to radiation during examination and radiotherapy. Consequently, it is important that training courses in radiation safety for radiological technologists, medical doctors and nurses be periodically carried out to ensure a more effective and safe utilization of radiation. Furthermore, it is important that such training be based on a practical education curriculum, including basic knowledge, technical training, and safe habits. In this paper, we discuss the appropriate role and attitudes of the radiological technologist in radiation safety education. (author)

Distribution of microorganisms were examined for the bucky tables in the radiology rooms of the department of radiological technology, the aprons, handles of various apparatus, handles of mobile radiological apparatus, and hands of the radiological technologists. As a result, relatively larger amounts of bacteria were found on the handles of the mobile radiological apparatus and the aprons. Among the isolated bacteria, Acinetobacter baumanni (7.3%), Klebsiella pneumoniae (6.7%), Staphylococcus aureus (3.9%), Serratia liquefaciens (1.7%), Enterobacter cloaceae (0.6%), Providenica rettgeri (0.6%) are known as the cause of nosocomial infection (hospital acquired infection). In addition, similar colonies were also found on the hands of the radiological technologists such as microorganisms of Klebsiella pneumoniae (8.4%), Staphylococcus aureus (6.6%), Yersinia enterocolotica (5.4%), Acinetobacter baumanni (4.2%), Enterobacter cloaceae (2.4%), Serratia liquefaciens (1.8%), Yersinia pseuotuberculosis (18%), Enterobacter sakazakii (1.2%), and Escherichia coli (0.6%). In particular, this result indicates clinical significance since Staphylococcus aureus and Escherichia coli show strong pathogenicity. Therefore, a continuous education is essential for the radiological technologists to prevent the nosocomial infection.

Persistence of Overseeded Cool-Season Grasses in Bermudagrass Turf

Directory of Open Access Journals (Sweden)

Thomas Serensits

2011-01-01

Full Text Available Cool-season grass species are commonly overseeded into bermudagrass turf for winter color. When the overseeded grass persists beyond the spring; however, it becomes a weed. The ability of perennial ryegrass, Italian (annual ryegrass, intermediate ryegrass, and hybrid bluegrass to persist in bermudagrass one year after seeding was determined. Perennial ryegrass, intermediate ryegrass, and Italian ryegrass produced acceptable ground cover in the spring after fall seeding. Hybrid bluegrass did not establish well, resulting in unacceptable cover. Perennial ryegrass generally persisted the most one year after seeding, either because of summer survival of plants or because of new germination the following fall. Plant counts one year after seeding were greater in the higher seeding rate treatment compared to the lower seeding treatment rate of perennial ryegrass, suggesting new germination had occurred. Plant counts one year after seeding plots with intermediate ryegrass or Italian ryegrass were attributed primarily to latent germination and not summer survival. Applications of foramsulfuron generally did not prevent overseeded species stand one year after seeding, supporting the conclusion of new germination. Although quality is less with intermediate ryegrass compared to perennial ryegrass, it transitions out easier than perennial ryegrass, resulting in fewer surviving plants one year later.

Illegal fishing poses a major threat to conservation of marine resources worldwide. However, there is still limited empirical research that quantifies illegal catch levels. We used the randomized response technique to estimate the proportion of divers and the quantities of loco (Concholepas concholepas) they extracted illegally. Loco have been managed for the past 17 years through a territorial user rights for fisheries system (TURFs) in Chile. Illegal fishing of loco was widespread within the TURFs system. Official reported landings (i.e., legal landings) accounted for 14-30% of the total loco extraction. Our estimates suggest that ignoring the magnitude of illegal fishing and considering only official landing statistics may lead to false conclusions about the status and trends of a TURFs managed fishery. We found evidence of fisher associations authorizing their members to poach inside TURFs, highlighting the need to design TURFs systems so that government agencies and fishers' incentives and objectives align through continuous adaptation. Government support for enforcement is a key element for the TURFs system to secure the rights that are in place. © 2017 Society for Conservation Biology.

Chung, Chadwick L R; Manga, Jasmin; McGregor, Marion; Michailidis, Christos; Stavros, Demetrios; Woodhouse, Linda J

2012-01-01

Interprofessional collaboration in health care is believed to enhance patient outcomes. However, where professions have overlapping scopes of practice (eg, chiropractors and physical therapists), "turf wars" can hinder effective collaboration. Deep-rooted beliefs, identified as implicit attitudes, provide a potential explanation. Even with positive explicit attitudes toward a social group, negative stereotypes may be influential. Previous studies on interprofessional attitudes have mostly used qualitative research methodologies. This study used quantitative methods to evaluate explicit and implicit attitudes of physical therapy students toward chiropractic. A paper-and-pencil instrument was developed and administered to 49 individuals (students and faculty) associated with a Canadian University master's entry-level physical therapy program after approval by the Research Ethics Board. The instrument evaluated explicit and implicit attitudes toward the chiropractic profession. Implicit attitudes were determined by comparing response times of chiropractic paired with positive versus negative descriptors. Mean time to complete a word association task was significantly longer (t = 4.75, p =.00) when chiropractic was associated with positive rather than negative words. Explicit and implicit attitudes were not correlated (r = 0.13, p =.38). While little explicit bias existed, individuals associated with a master's entry-level physical therapy program appeared to have a significant negative implicit bias toward chiropractic.

2009-01-01

Protective behavior of radiological technologists against radiation exposure is important to achieve reduction of the patient doses without compromising medical achievements. This study attempts to provide a basic model for the sophisticated intervention strategy that increases the level of the protective behavior of the technologists. The model was applied to real situations in Korea to demonstrate its utility. The results of this study are summarized as follows: First, the protective environment showed the highest relationship in the factors considered, r=0.637 (p<0.01). Secondly, the important factors were protective environment in environment characteristics, expectation for the protective behavior 0.228 (p<0.001), self efficacy 0.142 (p<0.001), and attitude for the protective behavior 0.178 (p<0.001) in personal characteristics, and daily patient -0.112 (p<0.001) and number of the participation in the education session for the protective behavior 0.074 (p<0.05). Thirdly, the final protective behavior model by a path analysis method had direct influence on the attitude 0.171 (p<0.01) and environment 0.405 (p<0.01) for the protective behavior, self efficacy 0.122 (p<0.01), expectation for the protective behavior 0.16 (p<0.01), and self-efficacy in the specialty of projects 0.154 (p<0.01). The acceptance of the model determined by the absolute fit index (GFI), 0.969, and by the incremental fit index (CFI), 0.943, showed very significant levels. Value of 2/df that is a factor applied to verify the acceptance of the model was 37, which implies that the result can be accepted in the desirable range. In addition, the parsimonious fit index configured by AGFI (0.890) and TLI (0.852) was also considered as a scale that accepts the model in practical applications. In case of the establishment of some specific intervention strategies based on the protective behavior model against harmful radiation effects proposed in this study, the strategy will provide an effective way

Ionizing and ultraviolet (UV) radiations are known to increase the risk of non-melanoma skin cancer. However, the effect of chronic or protracted exposure to ionizing radiation and the modifying effect of UV exposure on skin cancer risk are not well defined. We evaluated risk of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin among radiologic technologists in the United States. A total of 1,355 incident cases with BCC and 270 with SCC were ascertained in 65,304 white technologists between the baseline questionnaire survey in 1983-1989 and the follow-up survey in 1994-1998. Analysis by Cox's proportional hazard model, stratified by birth cohort and adjusted for potential confounders including pigmentation characteristics (skin complexion, eye and hair color) and estimated index of residential UV exposure, indicated significantly increased relative risks for BCC, but not for SCC, among early technologists who likely had high radiation exposure. Relative risks of BCC were 1.42 (95% CI: 1.12-1.79), 2.04 (95% CI: 1.44-2.88), and 2.17 (95% CI: 1.14-4.10) among those who first worked in the 1950s, 1940s, and before 1940, respectively (p for trend: <0.01), compared with technologists who first worked after 1960. The effects of ionizing radiation on BCC were not significantly modified by UV exposure (p for effect modification: 0.31), but they were modified by eye and hair color (p=0.01 and 0.03), with light eye or hair color conferring a higher radiation-related risk. In contrast, relative risks of both BCC and SCC significantly increased with increasing residential UV exposure index, and no modifying effects of pigmentation characteristics were observed. This study provides evidence of increased BCC risk associated with chronic, occupational exposure to a low-to-moderate level of ionizing radiation, which may be modified by pigmentation characteristics

1981-01-01

The Japan Association of Radiologic Technologists reported that, from 1941 to 1978, 395 deaths occurred among Japanese radiological technologists who belong to the association. Using these data, Sakka, Kitabatake and colleagues, and the present authors studied mortality and cause of death among these technologists for 11 years from 1955 to 1965, for 7 years from 1966 to 1972, and for 5 years from 1973 to 1977, respectively. In general, the number of cancer deaths in the three studies was less than expected. However, Kitabatake et al. and the present authors found that deaths from skin cancer were significantly more frequent than expected. The present authors recently estimated the cumulative doses of radiation exposure for the majority of deaths (268 out of 395). The mean dose of radiation related to cancer deaths was then compared with that for non-cancer deaths. Also the proportional mortality ratios for cancers were observed in relation to the estimated dose level. In the present study, however, statistical tests to assess for the relationship between mortality and dose of radiation exposure showed no correlation, for the majority of deaths from cancer.

Tifgreen, Tifway and Tifdwarf, sterile triploid (2n = 27)F 1 hybrids between Cynodon dactylon and C. transvaalensis, are widely used turf grasses bred at Tifton, Georgia. They cannot be improved by conventional breeding methods. Attempts to improve them by treating short dormant rhizome sections with EMS failed but exposing them to 7-9 kR of gamma radiation produced 158 mutants. These have been evaluated at Tifton, and Beltsville, Maryland, and nine that appear to be better than the parents in one or more characteristics were planted in 8 x 10 m plots in triplicate in 1977. Test results to date suggest that one or more of these will be good enough to warrant a name and release to the public. Coastcross-1 is an outstanding sterile F 1 hybrid Bermuda grass that gives 35% more beef per acre but lacks winter hardiness. Since 1971, several million sprigs of Coastcross-1 have been exposed to 7 kR and have been planted and screened for winter survival at the Georgia Mountain Experiment Station. Chlorophyll-deficient mutants have appeared and one mutant slightly, but significantly, more winter hardy than Coastcross-1 has been obtained. Sprigs of this mutant named Coastcross 1-M3 are being irradiated and screened in an attempt to increase its winter hardiness. (author)

2017-01-01

In order to examine how Radiological Technologists perceive the oriental doctor's use of Medical Imaging Equipment, surveys were conducted for the members of the Korean Radiological Technologists Association. The total number of respondents were 515 and 481, with 34 insincere responses removed caused of nonvalidated answer. The results of the analysis are as follows. Although there were no statistical significance in the difference in perception by location of residence, work place, and educational background, respondents with higher education showed a tendency to agree on the use of comprehensive medical imaging equipment, but tended to oppose the use of special medical imaging equipment. Differences in perception by gender showed a greater negative perception toward the oriental doctor's use of medical imaging equipment by women than men. In particular, women showed more negative tendency for oriental doctor's use of special medical imaging equipment such as MRI, CT, and ultrasound equipment compared to men, and this was statistically significant. The difference in perception by age showed that the oriental doctor's use of medical imaging equipment was negative in the 20∼30s, neutral in the 40∼50s, and positive in the 60s, which were statistically significant. The difference in perception by work experience showed that the longer the work experience was, the more positive it was toward oriental doctor's use of medical imaging equipment.

The efficacy of radiation therapy is to eradicate the tumor while preserving the integrity of normal tissues. Technological advances have allowed to develop techniques capable of modulating doses delivered to the target volume, providing more effective treatments. However, the operational complexity of these techniques makes the benefits offered are directly proportional to the chances of occurrences of serious errors. The objective of this work is to analyze the steps performed by the technician/technologist in Intensity Modulated Radiotherapy (IMRT), to detect possible errors in order to determine ways to mitigate them. After literature regarding errors in the radiation therapy, a prospective analysis was performed in the first half of 2012 in a radiation clinic located in the city of Rio de Janeiro, in which 11 technicians/technologists contributed to the survey data analysis. The method of risk analysis Failure Mode and Effects Analysis was used for prospective analysis of accidents/incidents, with respect to a qualitative assessment . The method allowed mapping 16 steps performed by technicians/technologists in the treatments with IMRT, identifying possible failures and their causes allowing to find ways to avoid possible errors. This analysis helped to confirm that the qualification and continuing education of technicians/technologists, allied to implement quality assurance programs and a computerized management can make a tool capable of IMRT to achieve the greatest challenge of radiotherapy.

Radiologists could improve their knowledge of contrast reaction management. The aim of this study was to evaluate to what degree the implementation of a didactic module resulted in improved technologist, nurse, and physician knowledge and comfort levels regarding the appropriate management of adverse reactions to contrast media. After institutional review board approval was obtained, nurses, technologists, and physicians involved in contrast administration were required to complete the educational module. Premodule and postmodule assessments were designed online. Each assessment included knowledge-based questions regarding the appropriate management of different types of contrast reactions, as well as questions regarding each respondent's comfort level with the treatment of various types of adverse contrast reactions. Comfort level was measured using a 6-point, Likert-type scale. Premodule and postmodule assessment scores were compared using McNemar's test. After module completion, physicians demonstrated a statistically significant improvement in knowledge regarding the proper administration route, concentration, and dose of intramuscular epinephrine. Physicians demonstrated significantly increased comfort with the administration of intramuscular epinephrine to adult and pediatric patients after module completion (P Didactic instruction in contrast reaction management results in improved knowledge and comfort levels for physicians, nurses, and technologists. However, a significant percentage of personnel still reported feeling uncomfortable treating an adverse contrast reaction after module completion, suggesting that didactic instruction alone may be inadequate.

The human embryo-fetus is highly radiosensitive and must be protected from excessive exposure to ionizing radiation. The maximum permissible dose equivalent for the developing embryo-fetus is set at 0.5 rem per year - the MPD level for members of the general public. Methods by which supervisory personnel can limit the fetal dose incurred by the occupational exposure of the mother are presented. It is recommended that supervisory personnel attempt to limit occupational exposure to the current non-occupational MPD levels for all x-ray technologists, thereby, insuring that the fetal dose limits are not surpassed and providing an added safety factor for personnel by keeping exposures as low as reasonably achievable

Technological economics: innovation, project management, and technology transfer

Energy Technology Data Exchange (ETDEWEB)

Bradbury, F R

1981-06-01

The relationship between economics and technology, as well as their interaction in production, productivity, project management, and in technology transfer processes are reviewed. Over the last two decades there has been an increasing interest by economists in the technologist's view of technical change and its mechanisms. The author looks at the zone between technology and economics, the technological economics, and discusses the theory of innovation recently sketched out by Nelson and Winter. The relevance to project management and technology transfer of contemporary writing by economists leads to the view that there are welcome signs of a convergence of the conceptual models now emerging and the practical problems of technology management and movement. Economists now seem more willing to come to terms with technology than technologists with economics. The economic significance of the multitudes of technically unglamorous activities in development work is seriously neglected as a result of over-emphasis on the spectacular technological break. If economic elegance were to be admitted to the criteria of success, one might get a significant improvement in the engineering of technological change. 29 references, 4 figure.

Simulation modelling: educational development roles for learning technologists

David Riley

2002-12-01

Full Text Available Simulation modelling was in the mainstream of CAL development in the 1980s when the late David Squires introduced this author to the Dynamic Modelling System. Since those early days, it seems that simulation modelling has drifted into a learning technology backwater to become a member of Laurillard's underutilized, 'adaptive and productive' media. Referring to her Conversational Framework, Laurillard constructs a pedagogic case for modelling as a productive student activity but provides few references to current practice and available resources. This paper seeks to complement her account by highlighting the pioneering initiatives of the Computers in the Curriculum Project and more recent developments in systems modelling within geographic and business education. The latter include improvements to system dynamics modelling programs such as STELLA®, the publication of introductory textbooks, and the emergence of online resources. The paper indicates several ways in which modelling activities may be approached and identifies some educational development roles for learning technologists. The paper concludes by advocating simulation modelling as an exemplary use of learning technologies - one that realizes their creative-transformative potential.

In order to examine how Radiological Technologists perceive the oriental doctor's use of Medical Imaging Equipment, surveys were conducted for the members of the Korean Radiological Technologists Association. The total number of respondents were 515 and 481, with 34 insincere responses removed caused of nonvalidated answer. The results of the analysis are as follows. Although there were no statistical significance in the difference in perception by location of residence, work place, and educational background, respondents with higher education showed a tendency to agree on the use of comprehensive medical imaging equipment, but tended to oppose the use of special medical imaging equipment. Differences in perception by gender showed a greater negative perception toward the oriental doctor's use of medical imaging equipment by women than men. In particular, women showed more negative tendency for oriental doctor's use of special medical imaging equipment such as MRI, CT, and ultrasound equipment compared to men, and this was statistically significant. The difference in perception by age showed that the oriental doctor's use of medical imaging equipment was negative in the 20∼30s, neutral in the 40∼50s, and positive in the 60s, which were statistically significant. The difference in perception by work experience showed that the longer the work experience was, the more positive it was toward oriental doctor's use of medical imaging equipment. Specifically, the most favorable tendency was found with work experience of more than 30 years, which was statistically significant. The results of this study revealed the Radiological Technologists' perceptions on the oriental doctor's use of Medical Imaging Equipment and this can contribute to the direction of public health promotion in the future.

Carbon emission and sequestration of urban turfgrass systems in Hong Kong

2014-01-01

Climate change is more than just a global issue. Locally released carbon dioxide may lead to a rise in global ambient temperature and influence the surrounding climate. Urban greenery may mitigate this as they can remove carbon dioxide by storing carbon in substrates and vegetation. On the other hand, urban greenery systems which are under intense management and maintenance may contribute to the emission of carbon dioxide or other greenhouse gases. The impact of urban greenery on carbon balance in major metropolitan areas thus remains controversial. We investigated the carbon footprints of urban turf operation and maintenance by conducting a research questionnaire on different Hong Kong turfs in 2012, and showed that turf maintenance contributed 0.17 to 0.63 kg Ce m −2 y −1 to carbon emissions. We also determined the carbon storage of turfs at 0.05 to 0.21 kg C m −2 for aboveground grass biomass and 1.26 to 4.89 kg C m −2 for soils (to 15 cm depth). We estimated that the carbon sink capacity of turfs could be offset by carbon emissions in 5–24 years under current management patterns, shifting from carbon sink to carbon source. Our study suggested that maintenance management played a key role in the carbon budget and footprint of urban greeneries. The environmental impact of turfgrass systems can be optimized by shifting away from empirically designed maintenance schedules towards rational ones based on carbon sink and emission principles. - Highlights: • Carbon storage capacity at 0.05 to 0.21 kg C m −2 for grasses and 1.26 to 4.89 kg C m −2 for soils (to 15 cm depth). • Turf maintenance contributed to carbon emissions at 0.17 to 0.63 kg Ce (carbon equivalent) m −2 y −1 . • Turf system respiration was negatively correlated with soil carbon capacity but only in the wet season. • Carbon stored in turfs could be offset by maintenance carbon emissions in 5–24 years

A Meta-Analysis of Soccer Injuries on Artificial Turf and Natural Grass

Jay H. Williams

2013-01-01

Full Text Available The goal of this investigation was to determine if playing or training on third-generation artificial turf (AT surfaces increases the incidence rate of injuries compared to natural grass (NG surfaces. This was accomplished by a meta-analysis performed on previously published research. Eight studies met the criteria of competitive soccer players, participation on both surfaces, and presentation of both exposure time and injury occurrence. Exposure time and injury incidence values were used to generate injury rate ratios (IRRs, AT/NG for all injuries as well as specific injuries. Subgroup analyses were also performed by condition (match or training, gender, and age (youth or adult. The overall IRR was 0.86 ( suggesting a lower injury risk on AT than NG. However, there was considerable heterogeneity between studies. Analyses of individual injuries and subgroups found that in many cases IRR values were significantly less than 1.0. In no case was the IRR significantly greater than 1.0. Based on this, it appears that the risk of sustaining an injury on AT under some conditions might be lowered compared to NG. However, until more is known about how issues such as altered playing styles affect injury incidence, it is difficult to make firm conclusions regarding the influence of AT on player safety.

A case of peritoneal malignant mesothelioma in a radiation technologist, who had worked in this field for 34 years, is reported. Histopathologically, a biopsy specimen from the retroperitoneal tumor revealed a biphasic type of malignant mesothelioma. Electron microscopy disclosed that the tumor cells contained prominent microvilli, basal laminae adjacent to the stroma, junctional complexes, desmosomes, tonofilaments, clusters of glycogen granules, well developed rough endoplasmic reticulum (RER), confronting cisternae showing direct continuity with the RER and membrane-bound granules suggestive of secretory activity. No increased amount of asbestos was detected in autopsied lung material or the peritoneal mesothelioma. The estimated cumulative dose of occupational irradiation was calculated to be about 40 to 50 rad at most. Irradiation was discussed in relation to the etiology of the peritoneal mesothelioma.

Full Text Available The food & drink (F&D sector in Europe ranks low in innovation and the European F&D industry has been losing importance in the global market. The food professionals, i.e., food scientists and technologists (FSTs, may not be meeting the varied demands of the sector. Here, we identify education, experience and skills of current FSTs and compare  geographic regions and employment areas. Between 2009 and 2012, 287 questionnaires representing over 4000 FSTs were collected from employers in 16 countries. Analyses showed that more than 80% of FSTs have a university degree; but only in Industry in the Central European region are most degrees in food science/technology. More than half of FSTs, and almost 60% in the South, have less than 10 years’ experience. The most common FST job title is Quality Manager, but with several variations based on region and employment area. Among skills, the most common is Communicating; found in over 90% of FSTs in all regions and employment areas. Food Safety is the most common of the food sector-specific skills, present in more than 75% of FSTs, yet there are differences in food sector skills based on employment area. Overall, these data suggest similarities among currently employed food professionals throughout Europe; they are young and highly educated, but also differences, especially in their food sector-specific skills. An understanding of the current FST should contribute to the improvement of FST training and thus benefit the European food sector.

Investigating the functional role of herbivorous fish species is important for understanding reef resilience and developing targeted management plans. Among the most abundant fish species on Indo-Pacific coral reefs are the surgeonfishes Acanthurus nigrofuscus and Ctenochaetus striatus. A. nigrofuscus is an herbivorous grazer that crops filamentous algae from the epilithic algal matrix, while C. striatus is detritivorous and was thought to `brush' detritus from the surface of filamentous algae, causing little damage to algal strands. Although the foraging mechanisms and general diet of these surgeonfishes have been established, their grazing impact on epilithic algal turfs has been unclear. This is the first study to quantify the grazing impact of A. nigrofuscus and C. striatus on algal turfs. Through aquaria trials using epilithic algal turf grown on experimental tiles, we found that both A. nigrofuscus and C. striatus consistently fed more intensively upon sparse/short algal turfs even though the yield of algae per bite was greater for dense/long algal turfs. As there was no difference in the nutritional value of sparse and dense algal turfs, we hypothesise that A. nigrofuscus avoided dense turf due to its significantly greater sediment load than sparse turf, while C. striatus likely avoided dense turf as it would become entangled in their bristle-like teeth. Unexpectedly, despite its dental morphology, C. striatus removed significantly more algal turf per hour than A. nigrofuscus, irrespective of canopy height. The capability of C. striatus to remove significant quantities of algal turf through their foraging activity implies that this abundant and widespread species may substantially affect algal turf dynamics. If this is the case, the exclusion of detritivorous Ctenochaetus species from herbivorous fish functional groups used in resilience monitoring will need to be re-evaluated.

2017-02-01

Full Text Available This paper describes the development of a new artificial turf surrogate surface (ATSS sampler for use in the measurement of mercury (Hg dry deposition. In contrast to many existing surrogate surface designs, the ATSS utilizes a three-dimensional deposition surface that may more closely mimic the physical structure of many natural surfaces than traditional flat surrogate surface designs (water, filter, greased Mylar film. The ATSS has been designed to overcome several complicating factors that can impact the integrity of samples with other direct measurement approaches by providing a passive system which can be deployed for both short and extended periods of time (days to weeks, and is not contaminated by precipitation and/or invalidated by strong winds. Performance characteristics including collocated precision, in-field procedural and laboratory blanks were evaluated. The results of these performance evaluations included a mean collocated precision of 9%, low blanks (0.8 ng, high extraction efficiency (97%–103%, and a quantitative matrix spike recovery (100%.

Noseck, Ulrich

2008-01-01

The relevance of analogues to radioactive waste management stems from the long timescales that have to be considered. Periods up to a million or more years into the future need to be considered and these are beyond experimental investigation and human experience. Within the last years the term 'Natural Analogue' has got a much wider meaning and includes man-made analogues as well. The role of natural analogues in the safety case depends amongst others on the time scale to be covered. Therefore, it is useful to classify them by the time period addressed in the study. Here it is referred to: industrial analogues which started earliest 150 years ago, archaeological analogues, which cover time frames between the past 10 000 and 150 years, and geological analogues, which usually cover time frames of more than 10 000 years and in most cases more than million years. The current interest in analogues in different countries is reflected by several recent review projects with emphasis on the application of natural analogue study results in performance assessment. The most recent international review was performed within the 5. EURATOM Framework of the EC by the NAnet project, a network on the review of natural analogue studies with emphasis on the application of analogues in long-term safety assessment and communication. The overall aim of the NAnet project was to review the past and present use and understanding of natural analogues, and to make recommendations for their future use. The project covered 'traditional' natural analogue studies, such as large-scale investigations of radionuclide transport around uranium ore bodies, and process or mechanistic analogue studies such as those examining natural glass and bentonite clay stability. To complete the picture, a restricted range of other studies of natural systems which employ a similar philosophy to analogues was also included in the scope. These included studies which have examined radionuclide transport and retardation

A study of radiological protection for women of reproductive age in diagnostic radiology. Questionnaire for medical radiation technologists

There has been great concern regarding the radiation protection for women of reproductive age when exposed to diagnostic radiation. The 10-day-rule proposed by the ICRP has not been recommended since 1983 because the risk to embryo and fetus within four weeks after menstruation may be small. However, some expects see that incomplete abandon of the 10-day-rule might cause confusion among the medical doctors and patients, and consequently unwarranted abortion happens. This paper surveyed the views of radiation technologies in hospitals and discussed how radiation exposure of women of reproductive age in medicine should be controlled. We found that the views to be 10-day-rule were spilt 50:50 and that radiation technologists do not necessarily think the 10-day-rule should be abandoned. Even the radiation technologists who are supposed to be able to explain to the patients the health risk following diagnostic exposure do not fully understand the risk involved. In conclusion, although a low-dose risk of diagnostic exposure should be sufficiently educated in order to obtain an exact understanding, the 10-day-rule may be useful in order to actually avoid any trouble in diagnostic radiology.

Color-blindness is the inability to perceive differences between some color that other people can distinguish. Using a literature search, the results indicate the prevalence of color vision deficiency in the medical profession and its on medical skills. Medical laboratory technicians and technologists employees should also screen for color blindness. This research aimed to study color blindness prevalence among Hospitals' Clinical Laboratories' Employees and Students in Tehran University of Medical Sciences (TUMS). A cross-sectional descriptive and analytical study was conducted among 633 TUMS Clinical Laboratory Sciences' Students and Hospitals' Clinical Laboratories' Employees to detect color-blindness problems by Ishihara Test. The tests were first screened with certain pictures, then compared to the Ishihara criteria to be possible color defective were tested further with other plates to determine color - blindness defects. The data was saved using with SPSS software and analyzed by statistical methods. This is the first study to determine the prevalence of color - blindness in Clinical Laboratory Sciences' Students and Employees. 2.4% of TUMS Medical Laboratory Sciences Students and Hospitals' Clinical Laboratories' Employees are color-blind. There is significant correlation between color-blindness and sex and age. But the results showed that there is not significant correlation between color-blindness defect and exposure to chemical agents, type of job, trauma and surgery history, history of familial defect and race. It would be a wide range of difficulties by color blinded students and employees in their practice of laboratory diagnosis and techniques with a potentially of errors. We suggest color blindness as a medical conditions should restrict employment choices for medical laboratory technicians and technologists job in Iran.

The new radiation protection ordinance for the first time acknowledges the role of the nuclear medicine technologists for the technical assistance in the use of radiopharmaceuticals and radiation with human beings in medicine. Therefore changes are required for the technologists in terms of their qualification and continuing education during their professional life and in the daily routine in a nuclear medicine department. The new ordinance clearly defines which group of people is allowed to work as nuclear medicine technologists and also which special knowledge in radiation protection is mandatory to make sure that nobody without this certified education is performing the work of a nuclear medicine technologist. The new effective dose limit for people working with radiation will not change the daily work, but new regulations for pregnant women or breastfeeding mothers working in nuclear medicine will bring dramatic changes.

Li, L; Qu, R

2004-01-01

Common bermudagrass, Cynodon dactylon, is a widely used warm-season turf and forage species in the temperate and tropical regions of the world. Improvement of bermudagrass via biotechnology depends on improved tissue culture responses, especially in plant regeneration, and a successful scheme to introduce useful transgenes. When the concentration of 6-benzylaminopurine was adjusted in the culture medium, yellowish, compact calluses were observed from young inflorescence tissue culture of var. J1224. Nine long-term, highly regenerable callus lines (including a suspension-cultured line) were subsequently established, of which six were used for biolistic transformation. Five independent transgenic events, with four producing green plants, were obtained following hygromycin B selection from one callus line. Three transgenic events displayed resistance to the herbicide glufosinate, and one of these showed beta-glucuronidase activity since the co-transformation vector used in the experiments contained both the gusA and bar genes.

Species interactions can maintain resistance of subtidal algal habitats to an increasingly modified world

2015-07-01

Full Text Available Current trends in habitat loss have been forecast to accelerate under anticipated global change, thereby focusing conservation attention on identifying the circumstances under which key species interactions retard habitat loss. Urbanised coastlines are associated with broad-scale loss of kelp canopies and their replacement by less productive mats of algal turf, a trend predicted to accelerate under ocean acidification and warming (i.e. enhanced CO2 and temperature. Here we use kelp forests as a model system to test whether efforts to maintain key species interactions can maintain habitat integrity under forecasted conditions. First, we assessed whether increasing intensity of local human activity is associated with more extensive turf mats and sparser canopies via structured field observations. Second, we experimentally tested the hypothesis that intact canopies can resist turf expansion under enhanced CO2 and temperature in large mesocosms. In the field, there was a greater proportion of turf patches on urbanised coasts of South Australia than in agricultural and urban catchments in which there was a greater proportion of canopy-forming algae. Mesocosm experiments revealed this expansion of turfs is likely to accelerate under increases in CO2 and temperature, but may be limited by the presence of intact canopies. We note that even in the presence of canopy, increases in CO2 and temperature facilitate greater turf covers than occurs under contemporary conditions. The influence of canopy would likely be due to shading of the understorey turfs which, in turn, can modify their photosynthetic activity. These results suggest that resistance of habitat to change under human-dominated conditions may be managed via the retention of key species and their interactions. Management that directly reduces the disturbance of habitat-forming organisms (e.g. harvesting or reverses loss through restoration may, therefore, reinforce habitat resistance in an

These multi-component systems are comprised of a range of polymeric and elastomeric materials that exhibit non-linear and strain rate dependent behaviours under the complex loads applied from players and equipment. To further study and better understand the behaviours of these systems, the development of a numerical model to accurately predict individual layers’ behaviour as well as the overall system response under different loading conditions is necessary. The purpose of this study was to characterise and model the mechanical behaviour of a rubber shockpad found in 3G artificial surfaces for vertical shock absorption using finite element analysis. A series of uniaxial compression tests were performed to characterise the mechanical behaviour of the shockpad. Compression loading was performed at 0.9 Hz to match human walking speeds. A Microfoam material model was selected from the PolyUMod library and optimised using MCalibration software before being imported into ABAQUS for analysis. A finite element model was created for the shockpad using ABAQUS and a compressive load applied to match that of the experimental data. Friction coefficients were altered to view the effect on the loading response. The accuracy of the model was compared using a series of comparative measures including the energy loss and root mean square error.

In order to type the sausage-shaped bacteria forming A-type sulfur-turf, cell length distributions and physics-chemical conditions of hot spring waters were investigated on twelve samples collected from all over Japan. The frequency distributions of the cell length of eight samples were bimodal, while the other four samples were unimodal. In seven samples with bimodal distributions, two types (large and small) of the sausage-shaped bacteria could be differentiated. The cell length of the large-type was between 10.1 and 31.9{mu}m, while that of the small-type ranged 2.2 to 6.6{mu}m. The pH of seven hot spring waters were between 6 and 8, and the two types (large and small) formed together sulfur-turf. In contrast, pH of the three hot springs were over 8, and the two types of the sausage-shaped bacteria could not be detected in the sulfur-turf. Therefore, it is reasonable to set a third type of the sausage-shaped bacteria which prefers high-pH (over 8) and low calcium condition. The cell lengths of the third type were in the range of 5.5 to 8.6{mu}m, which correspond to the sausage-shaped bacteria of medium size. 20 refs., 5 figs., 2 tabs.

The demand for nuclear medicine technologists (NMTs) in Kuwait has increased, especially with the introduction of multimodality imaging systems. In order to increase the number of NMTs in the workforce and retain the existing NMTs, there should be a better way to motivate them. To find out how satisfied NMTs are and the factors that motivate them. An interview was conducted with 40 randomly selected NMTs to explore deep-seated emotions and attitudes that were related to motivation. Questions about the recognition NMTs receive from the general public, whether they are acknowledged as significant contributors to health services, ways to improve the standing of NMTs in society, and the clarity of the job description were included. A questionnaire survey was then conducted with 100 randomly selected NMTs. The questions were designed to elicit wider perspective of the information obtained from the interviews. The results show a need for attention in the Ministry of Health to NMTs for recognition, motivation, and improvement. Giving the NMTs their own identity and opportunities to be part of decision-making in the health team would influence more students to join nuclear medicine departments and give more self-confidence to the existing NMTs.

The Commercial Technology Mission is a primary NASA mission, comparable in importance to those in aeronautics and space. This paper will discuss TechTracS, NASA Commercial Technology Management System that has been put into place in FY 1995 to implement this mission. This system is designed to identify and capture the NASA technologies which have commercial potential into an off-the-shelf database application, and then track the technologies' progress in realizing the commercial potential through collaborations with industry. The management system consists of four stages. The first is to develop an inventory database of the agency's entire technology portfolio and assess it for relevance to the commercial marketplace. Those technologies that are identified as having commercial potential will then be actively marketed to appropriate industries—this is the second stage. The third stage is when a NASA-industry partnership is entered into for the purposes of commercializing the technology. The final stage is to track the technology's success or failure in the marketplace. The collection of this information in TechTracS enables metrics evaluation and can accelerate the establishment on direct contacts between and NASA technologist and an industry technologist. This connection is the beginning of the technology commercialization process.

The study examined the changes in the decreased facial exposure dose for radiological technologists depending on increased distance between the workers and the X-ray tube head during intraoral radiography. First, the facial phantom similar to the human tissues was manufactured. The shooting examination was configured to the maxillary molars for adults (60 kVp, 10 mA, 50 msec) and for children (60 kVp, 10 mA, 20 msec), and the chamber was fixed where the facial part of the radiation worker would be placed using the intraoral radiography equipment. The distances between the X-ray tube head and the phantom were set to 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, 35 cm, and 40 cm. The phantom was radiated 20 times with each examination condition and the average scattered doses were examined. The rate at the distance of 40 cm decreased by about 92.6% to 7.43% based on the scattered rays radiated at the distance of 10 cm under the adult conditions. The rate at the distance of 40 cm decreased by about 97.6% to 2.58% based on the scattered rays radiated at the distance of 10 cm under the children conditions. Protection from the radiation exposure was required during the dental radiographic examination.

We made a detailed study on the course of study in radiation safety control prescribed on March 28, 2003. Questionnaires were sent to 39 training schools for radiological technology, to which 66.7% replied (26/39). Subjects on radiation safety control must include knowledge and technology in both radiation control and medical safety. The contents for instruction of radiation control were in accordance with those given in the traditional program; however, some discrepancies were found in the contents of medical safety. As medical safety, emphasized by the revised Medical Service Law, is regarded as very important by many hospitals, safety control education that include medical ethics should be required as part of the curriculum in the training schools for radiological technologists.

The Aichi Association of Radiological Technologists executed the survey according to the task of radiation control in Aichi prefecture. The survey investigated the number of clinics/hospitals who own radiation dosimeters. The association also measured outputs using glass dosimeter (GD-450) manufactured by Chiyoda Technical in diagnostic X ray. The purpose and significance of the survey are: to illustrate that the radiation control task is not involved as routine maintenance work, to examine why the task is not routinely performed, to investigate the number of clinics/hospitals who own diagnostic X ray radiation dosimeters, to inform that the use of dosimeter is essential to achieve accurate measurement for exposed dose, and to motivate the significance of radiation control in routine work. The result of the survey clearly indicated the necessity of radiation control, and suggested the information needed for the Aichi Association of Radiological Technologists to determine the guideline for the medical radiation exposed dose.

A recent publication from our centre revealed a disturbing finding of a significant incidence of adult fingers seen on the pediatric intensive care unit (PICU) chest radiographs. This is inappropriate occupational exposure to diagnostic radiation. We hypothesized that the incidence of adult fingers on PICU chest radiographs would decline after radiation safety educational seminars were given to the medical radiation technologists and PICU staff. The present study's objectives were addressed by using a pretest-posttest design. Two cross-sectional PICU chest radiograph samples, taken before and after the administration of radiation safety education for our medical radiation technologists and PICU staff, were compared by using a χ 2 test. There was a 61.2% and 76.9% reduction in extraneous adult fingers, directly exposed to the x-ray beam and those seen in the coned regions of the film, respectively, on PICU chest radiographs (66.7% reduction overall). This reduction was statistically significant (χ2 = 20.613, P < .001). Limiting unnecessary occupational radiation exposure is a critical issue in radiology. There was a statistically and clinically significant association between radiation safety education and the decreased number of adult fingers seen on PICU chest radiographs. This study provides preliminary evidence in favour of the benefit of radiation safety seminars. (author)

Analysis of Medical Equipment Management in Relation to the Mandatory Medical Equipment Safety Manager (MESM in Japan

Full Text Available Half a decade has passed since the fifth revision of the medical law and mandatory appointment of a medical equipment safety manager (MESM in hospitals in Japan. During this period, circumstances have changed regarding maintenance of medical equipment (ME. We conducted a survey to examine these changes and the current situation in ME management. Maintenance of ME and related work were found to have increased in many hospitals, but the number of clinical engineering technologists (CETs has only slightly increased. The appointed MESM was a CET or physician in most hospitals. In hospitals where physicians were appointed as the MESM, 81% had operation managers. Many respondents commented that it was difficult for one person to cover all the tasks required by the MESM, due to a lack of knowledge, too much work, or other reasons. This suggests the importance of an operation manager for ME to work under the MESM.

Chromosomal aberrations in the lymphocytes of radiation technologists (RT) were analyzed by the trypsin G-banding method to study the late effects of long-term exposure to low doses of radiation. Structural aberrations were identified in 384 (2.5%) of 15442 cells analyzed from 53 RT as compared to 177 (1.6%) of 11136 cells from 36 healthy controls. Stable aberrations were the most frequent in both groups and were either translocations or deletions. Unstable aberrations were mainly acentric fragments in both groups. The frequency of translocations and acentric fragments was significantly higher in the RT than in the controls and was highest in the RT over 50 years. The highest frequency observed in the >50 age group was attributed to the unknown for cumulative dose prior to introduction of film badges. Frequency of chromosomal aberrations correlated with the estimated dose from the film badges and years of experience of each RT based on the equation y=0.22+0.37D+4.35D 2 , where y is overall frequency of chromosomal aberrations and D is the estimated radiation dose in Sv.

The need to manage, save and disseminate technical scientific knowledge as part of the technology transfer process requires the implementation of Corporate Document and Records Management Systems that support a cultural change in the management of documentation generated in organizations as a result of their research work. In the CIEMAT, most knowledge is developed in R and D projects led by scientists and technologists and managed by the research support personnel and, therefore, it is very important to efficiently manage and control the life cycles of these projects. This article describes the implementation of a corporate document and records management system in the CIEMAT. (Author)

2008-01-01

A questionnaire survey of medical physicists and quality managers for radiation therapy was performed by the Japanese Society for Therapeutic Radiology and Oncology (JASTRO) Future Planning Committee. We mailed the questionnaire to 726 radiotherapy facilities with the answers returned from 353 radiotherapy facilities. The result showed 178 facilities were staffed by radiotherapy workers who were licensed medical physicists or quality managers. A staff of 289 was licensed radiotherapy workers. Most of the staff were radiotherapy technologists. Quality control for radiation therapy was rated satisfactory according to each facility's assessment. Radiation therapy of high quality requires continued education of medical physicists and quality managers, in addition to keeping up with times for quality control. (author)

Multidisciplinary management--an opportunity for service integration.

The management team of the future will enter an environment requiring facilitation, participation, clinical, and empowerment skills. Those individuals who possess a clinical orientation as well as business expertise will be sought to manage multidisciplinary units. The rapid changes in the health-care environment have forced organizations to restructure their operations. To achieve quality care, customer satisfaction, cost-effectiveness, and efficiency, service integration across the organization will be required. As we approach the 21st century, this standard will evolve until "all levels are managing patient care." Some of the restructuring trends occurring in the health-care industry have been collaboration service integration, management consolidation, and job elimination. The emphasis for the multidisciplinary manager of the future will include integrating the professional and clinical services, managing information, building community partnerships, promoting physician collaboration, and managing the change process. A model organization in the next century will move toward a people-oriented system with inclusion and empowerment initiatives. Service integration will affect all organizations, but the disciplines within the Clinical Support System will be the most affected. Future opportunities of leadership will exist for pathologists, nurses, or medical technologists as the professional silos of managers and clinicians continue to crumble.

A QUALITY SPIRAL FOR KNOWLEDGE MANAGEMENT

Full Text Available Management of technology is crucial for all of us. It involves dealing with technical issues across a broad spectrum of functional areas. Recent innovations in the form of total quality management, reengineering work process, flexible manufacturing system have one thing in common serving the customer well thought improved operational efficiency. For instant Total Quality Management advocates emphasize the importance of achieving greater quality and flexibility at lower cost and waste. Technology is forcing organizations to become more competitive at every instance there are innovations taking place. The rapid development of models or prototypes may largely reduce the development cost and the product development cycle. In addition, they can be used in test markets prior to the entry of the product in the final production and commercialization stage. Since it is based on technological changes or improvements, the development of such models or prototypes is usually conducted by technologist, who has no regard for the cost of such a development.

A written directive is required by the U.S. Nuclear Regulatory Commission for any use of 131 I above 1.11 MBq (30 μCi) and for patients receiving radiopharmaceutical therapy. This requirement has also been adopted and must be enforced by the agreement states. As the introduction of new radiopharmaceuticals increases therapeutic options in nuclear medicine, time spent on regulatory paperwork also increases. The pressure of managing these time-consuming regulatory requirements may heighten the potential for inaccurate or incomplete directive data and subsequent regulatory violations. To improve on the paper-trail method of directive management, we created a software tool using a Health Insurance Portability and Accountability Act (HIPAA)-compliant database. This software allows for secure data-sharing among physicians, technologists, and managers while saving time, reducing errors, and eliminating the possibility of loss and duplication. Methods: The software tool was developed using Visual Basic, which is part of the Visual Studio development environment for the Windows platform. Patient data are deposited in an Access database on a local HIPAA-compliant secure server or hard disk. Once a working version had been developed, it was installed at our institution and used to manage directives. Updates and modifications of the software were released regularly until no more significant problems were found with its operation. Results: The software has been used at our institution for over 2 y and has reliably kept track of all directives. All physicians and technologists use the software daily and find it superior to paper directives. They can retrieve active directives at any stage of completion, as well as completed directives. Conclusion: We have developed a software solution for the management of written directives that streamlines and structures the departmental workflow. This solution saves time, centralizes the information for all staff to share, and decreases

Full Text Available Coral reef degradation increases coral interactions with filamentous turf algae (FTA and macroalgae, which may result in chronic stress for the corals. We evaluated the effects of short (2.5 month and long (10 month periods of FTA removal on tissue thickness (TT, zooxanthellae density (ZD, mitotic index (MI, and concentration of chlorophyll a (Chl a in Montastraea annularis at the beginning and end of gametogenesis. Ramets (individual lobes within a colony consistently surrounded by FTA and ramets surrounded by crustose coralline algae (CCA were used as controls. FTA removal reduced coral stress, indicated by increased TT and ZD and lower MI. The measured effects were similar in magnitude for the short and long periods of algal removal. Ramets were more stressed at the end of gametogenesis compared with the beginning, with lower ZD and Chl a cm(-2, and higher MI. However, it was not possible to distinguish the stress caused by the presence of FTA from that caused by seasonal changes in seawater temperature. Ramets surrounded by CCA showed less stress in comparison with ramets surrounded by FTA: with higher TT, Chl a cm(-2 and ZD, and lower MI values. Coral responses indicated that ramets with FTA suffered the most deleterious effects and contrasted with those measured in ramets surrounded by CCA. According to published studies and our observations, there could be at least six mechanisms associated to FTA in the stress caused to M. annularis by FTA. Owing to the high cover of FTA (in contrast to macroalgae and CCA in the Caribbean, the chronic stress, the overgrowth and mortality that this functional algal group can cause on M. annularis species complex, a further decline of this important reef-building coral in the Caribbean is expected.

To lead a project effectively, one has to establish and maintain the flexibility to take appropriate actions when needed. Overconstrained situations should be avoided. To get on top of matters and stay there, a manager needs to anticipate what it will take to successfully complete the job. Physical and financial resources, personnel, and management structure are all important considerations. Carving out the necessary turf up front can make a world of difference to the project's outcome. After the "what," "where," and "when" of a project are nailed down, the next question is "how" to do the job. When I first interviewed for the job of Science Payload Manager on the Advanced Composition (ACE) Explorer mission, Dr. Edward Stone (ACE Principal Investigator) asked, "Al, give me an idea of your management style." It was a question I had not considered before. I thought about it for a few seconds and then answered, "Well, the first descriptive term that comes to mind is the word "tranquility". That seemed to startle him. So I added, "I guess what I mean is, that if the situation is tranquil and the project is running smoothly, then I've anticipated all the problems and taken necessary actions to head them off." He then asked: "Have you ever reached this state?" "No," I admitted, "but I strive for it." That seemed to satisfy him because I got the job.

Ionizing radiations are used in areas such as health, industry and safety, not only in the private sector, but also in the public. Thus, it is necessary the radiological protection, a set of studies and practices that increases the safety in these applications, where the professional involved is the technologist in radiology. The objective was to analyze the contents effectively required by the Brazilian public agencies in their competitions for radiology technologist, regarding the area of radiological protection, identifying their profile of requirement. It consisted of three stages: first, a survey of all the public competitions already carried out in the country up to the end of 2016, that requested a diploma of graduation in Technology in Radiology; second, all the specific questions were collected and grouped in an electronic text file; third, issues involving radiological protection were segregated, using as reference the 2017 edition of the National Nuclear Energy Commission's General Proof of Radioprotection Supervision. The results showed that almost 40% of the competition questions were about radiation protection. From this sampling, the topics most covered were: radiological safety (36%), fundamentals of atomic and nuclear physics (24%) and biological effects of radiation (16%). It is concluded that the competitions for radiologist technologist have the profile of concentration of exigency in radiological safety, fundamentals of atomic and nuclear physics and biological effects of the radiations.

The use of radiology examinations in medicine has been growing worldwide. Annually an estimated 3.1 billion radiologic exams are performed. According to this expansion of medical radiation exposure, it has been hard to pay no attention to the effects of medical radiation exposures in the exposure from different types of radiation source. This study, therefore, was aimed to assess the association of medical and occupational radiation exposure in Korean radiologic technologists and evaluate necessity for its consideration in occupational studies. This study did not show the strong association between medical radiation exposure and occupational radiation exposure except several modalities with specific frequency. These results are preliminary but certainly meaningful for interpretation of epidemiologic finding, therefore, we need further evaluation specially for the repeatedly exposed imaging tests and high dose procedures that presented somewhat weak relationship in this study linked with health outcomes of radiation exposure. This study did not show the strong association between medical radiation exposure and occupational radiation exposure except several modalities with specific frequency.

2018-01-01

Bacterial etiolation and decline has developed into a widespread issue with creeping bentgrass (CBG) (Agrostis stolonifera) putting green turf. The condition is characterized by an abnormal elongation of turfgrass stems and leaves that in rare cases progresses into a rapid and widespread necrosis and decline. Recent reports have cited bacteria, Acidovorax avenae and Xanthomonas translucens, as causal agents; however, few cases exist where either bacterium were isolated in conjunction with turf exhibiting bacterial disease symptoms. From 2010 to 2014, turfgrass from 62 locations submitted to the NC State Turf Diagnostic Clinic exhibiting bacterial etiolation and/or decline symptoms were sampled for the presence of bacterial pathogens. Isolated bacteria were identified using rRNA sequencing of the 16S subunit and internal transcribed spacer region (16S-23S or ITS). Results showed diverse bacteria isolated from symptomatic turf and A. avenae and X. translucens were only isolated in 26% of samples. Frequently isolated bacterial species were examined for pathogenicity to 4-week-old 'G2' CBG seedlings and 8-week-old 'A-1' CBG turfgrass stands in the greenhouse. While results confirmed pathogenicity of A. avenae and X. translucens, Pantoea ananatis was also shown to infect CBG turf; although pathogenicity varied among isolated strains. These results illustrate that multiple bacteria are associated with bacterial disease and shed new light on culturable bacteria living in CBG turfgrass putting greens. Future research to evaluate additional microorganisms (i.e., bacteria and fungi) could provide new information on host-microbe interactions and possibly develop ideas for management tactics to reduce turfgrass pests.

Individual and collective radiation doses received by Canadian radiation technologists (RTs) working in diagnostic radiology, nuclear medicine and radiotherapy are summarized for the period 1978 to 1988. The data were obtained directly from the National Dose Registry, Department of National Health and Welfare. Over the 11-year study period the mean annual dose equivalent fluctuated around 0.2, 1.8 and 1.1 mSv for RTs working in diagnostic radiology, nuclear medicine and radiotherapy respectively. Over the same period the occupational collective dose equivalent decreased in diagnostic radiology by 44% and radiotherapy by 35%, and increased in nuclear medicine by 45%. Approximately 10 000 RTs are monitored each year, with an estimated total occupational collective dose equivalent of about 3.6 person-sievert. Analysis of dose distribution data showed that only 1.3% of all monitored RTs received an annual whole-body dose equivalent greater than the current legal limit for members of the public (5 mSv). Approximately half of the RTs working in nuclear medicine and radiotherapy received an annual dose equivalent in excess of 0.5 mSv; only 7.3% of their diagnostic radiology counterparts exceeded this level. Demographic data showed a high preponderance of young women in all three RT classifications, and an analysis of the radiation risks to this occupational group revealed increases of up to 12% above the risk associated with a 'standard' adult working population exposed to the same collective dose equivalent.

Municipalities have been replacing grass fields with artificial turf, which uses crumb rubber infill made from recycled tires. Crumb rubber contains hydrocarbons, organic compounds, and heavy metals. Water runoff from crumb rubber fields contains heavy metals. These components can damage the environment. We contaminated topsoil with new crumb rubber and measured its impact on earthworms and soil microbes. Specifically, we compared soil microbe activity and earthworm health, survivorship, and longevity in heat and light stress under two soil regimes: clean topsoil and clean topsoil contaminated with crumb rubber. We then characterized levels of metals, nutrients, and micronutrients of both soil treatments and compared those to published New York soil background levels and to levels set by the New York State Department of Environmental Conservation (DEC) as remediation goals. We found that: 1) contaminated soil did not inhibit microbial respiration rates, 2) earthworm survivorship was not impacted by exposure to contaminated soil, 3) earthworms' ability to cope with heat and light stress remained unchanged after living in contaminated soil, but 4) earthworms living in contaminated soil gained 14% less body weight than did earthworms living in uncontaminated soil. We also found that, with the exception of zinc, heavy metals in our contaminated soil did not exceed the background levels found throughout New York State or the remediation targets set by the DEC.

Novel solutions to conserve biodiversity whilst allowing for resource harvesting are urgently needed. In marine systems, Territorial User Rights for Fisheries (TURFs) are promoted to enable sustainable use of resources. We investigate the potential for synergies between nature-based tourism and TURFs on Chile's central coast. Of 135 recreational divers surveyed, 77% indicated that the fish species they preferred sighting were declining and 80% indicated that they would dive more often in TURFs, which have higher abundance of favoured species. Regression analysis shows that respondents that perceive that TURFs fulfil a conservation function are more willing to pay to dive in a TURF. However, respondents who understand the bureaucratic functioning of a TURF are less willing to pay, and there is diversity in how divers feel payments should be made. A participatory approach is required to navigate these complexities to achieve synergies between nature-based tourism and resource harvesting in TURFs.

Management of pediatric radiation dose using Canon digital radiography

International Nuclear Information System (INIS)

Arreola, M.; Rill, L.

2004-01-01

A Canon CXDI-11 digital radiography (DR) system has been in use at Shands Hospital at the University of Florida for the past 2 1/2 years. A first clinical implementation phase was utilized to develop imaging protocols for adult patients, with a second phase incorporating pediatric chest and abdominal studies a few months later. This paper describes some of the steps taken during the modality implementation stages, as well as the methodologies and procedures utilized to monitor compliance by the technologists. The Canon DR system provides the technologist with an indication of the radiation exposure received by the detector (and thus of the patient dose) by means of an indirect exposure level number called the reached exposure (REX) value. The REX value is calculated by the system based on the default grayscale curve preselected for a given anatomical view and used by the system to optimize the appearance of the image. The brightness and contrast of the image can be modified by the user at the QC/control screen for the purpose of improving the appearance of the image. Such changes modify the actual grayscale curve (position and slope, respectively) and thus the calculated REX value. Thus, undisciplined use of the brightness and contrast functions by the technologist can render the REX value meaningless as an exposure indicator. The paper also shows how it is possible to calibrate AEC (phototimer) systems for use with the Canon DR system, and utilize the REX value as a valuable dose indicator through proper training of technologists and strict, disciplined QC of studies. A team consisting of the site's medical physicist, radiologists, and technologists, as well as Canon engineers, can work together in properly calibrating and setting up the system for the purposes of monitoring patient doses (especially pediatric) in DR studies performed in a Canon DR system.

Development and implementation of an electronic interface for complex clinical laboratory instruments without a vendor-provided data transfer interface

Directory of Open Access Journals (Sweden)

Gary E Blank

2011-01-01

Full Text Available Background: Clinical pathology laboratories increasingly use complex instruments that incorporate chromatographic separation, e.g. liquid chromatography, with mass detection for rapid identification and quantification of biochemicals, biomolecules, or pharmaceuticals. Electronic data management for these instruments through interfaces with laboratory information systems (LIS is not generally available from the instrument manufacturers or LIS vendors. Unavailability of a data management interface is a limiting factor in the use of these instruments in clinical laboratories where there is a demand for high-throughput assays with turn-around times that meet patient care needs. Materials and Methods: Professional society guidelines for design and transfer of data between instruments and LIS were used in the development and implementation of the interface. File transfer protocols and support utilities were written to facilitate transfer of information between the instruments and the LIS. An interface was created for liquid chromatography-tandem mass spectroscopy and inductively coupled plasma-mass spectroscopy instruments to manage data in the Sunquest® LIS. Results: Interface validation, implementation and data transfer fidelity as well as training of technologists for use of the interface was performed by the LIS group. The technologists were familiarized with the data verification process as a part of the data management protocol. The total time for the technologists for patient/control sample data entry, assay results data transfer, and results verification was reduced from approximately 20 s per sample to <1 s per sample. Sample identification, results data entry errors, and omissions were eliminated. There was electronic record of the technologist performing the assay runs and data management. Conclusions: Development of a data management interface for complex, chromatography instruments in clinical laboratories has resulted in rapid, accurate

The circumstances surrounding the certification examination for cytotechnologists in Japan are closely related with the history of the Japanese Society of Clinical Cytology. The examination for cytotechnologists is open only to medical technologists. The examination has two parts: primary and secondary. Qualification for candidacy for the secondary examination requires candidates to have passed the primary examination. The rate of successful applicants in the past 10 years was approximately 25-40%. Certified cytotechnologists are required to renew their qualifications every 4 years for their study and job history. I will present the purpose of the qualification update system, future themes, the reporting system for cytodiagnosis, and the possibility that the certification examination for cytotechnologists will become a national examination.

Clarifying functional roles: algal removal by the surgeonfishes Ctenochaetus striatus and Acanthurus nigrofuscus

Tebbett, Sterling B.; Goatley, Christopher H. R.; Bellwood, David R.

The lined bristletooth, Ctenochaetus striatus, and the brown surgeonfish, Acanthurus nigrofuscus, are among the most abundant surgeonfishes on Indo-Pacific coral reefs. Yet, the functional role of these species has been the focus of an ongoing debate lasting at least six decades. Specifically, to what extent are C. striatus herbivorous like the visually similar A. nigrofuscus? To address this question, we used natural feeding surfaces, covered with late successional stage reef-grown algal turfs, to examine turf algal removal by the two species. Surfaces exposed to C. striatus in laboratory experiments exhibited no significant reductions in turf length or area covered by turfing algae. In marked contrast, A. nigrofuscus reduced turf length by 51% and area covered by turfing algae by 15% in 1 h. The gut contents of specimens from the reef revealed that A. nigrofuscus predominantly ingests algae (the dominant item in 79.6-94.7% of gut content quadrats), while C. striatus ingests detritus and sediments (dominant in 99.6-100% of quadrats). Therefore, C. striatus ingests detritus and sediment, leaving mature algal turfs relatively intact, while A. nigrofuscus directly removes and ingests turf algae. The function of C. striatus differs from cropping herbivorous surgeonfishes such as A. nigrofuscus. On coral reefs, C. striatus brush detrital aggregates from algal turfs, removing microorganisms, organic detritus and inorganic sediment. Confusion over the functional role of C. striatus may stem from an inability to fit it into a single functional category.

To clarify the long-term effects of occupational exposure to low doses of radiation, Epstein-Barr virus (EBV)-specific antibody titers in sera from 104 radiological technologists (R.T.) and 118 controls in Kumamoto prefecture were measured by the immunofluorescence method. Antibody titers to viral capsid antigen (VCA)-IgG increased with the years of experience as R.T., and the prevalence of abnormal antibody titers to both VCA-IgG and early antigen (EA)-IgG were significantly higher in R.T. with over 15 years of experience or 30 rads of cumulative radiation dose than in the controls. However, there was no correlation between exposure and the frequency of abnormal EBV-associated nuclear antigen (EBNA) antibody titers. The EBV-specific antibody titers of 24 Hiroshima atomic-bomb survivors were also measured. They were similar to those of the R.T. with over 30 years of experience. The EBV-specific antibody titers of R.T. suggest that there may be an impairment of immunologic competence after continuous long-term exposure to low doses of radiation. Also, the correlation of EBV-specific antibody titers and frequency of cells with chromosome aberrations in 53 R.T. was studied. Some correlations were found between the antibody titers to both of the VCA-IgG and EBNA and the frequency of cells with chromosome aberrations.

Marine fish stocks are in many cases extracted above sustainable levels, but they may be protected through restricted-use zoning systems. The effectiveness of these systems typically depends on support from coastal fishing communities. High management costs including those of enforcement may, however, deter fishers from supporting marine management. We incorporated enforcement costs into a spatial optimization model that identified how conservation targets can be met while maximizing fishers' revenue. Our model identified the optimal allocation of the study area among different zones: no-take, territorial user rights for fisheries (TURFs), or open access. The analysis demonstrated that enforcing no-take and TURF zones incurs a cost, but results in higher species abundance by preventing poaching and overfishing. We analyzed how different enforcement scenarios affected fishers' revenue. Fisher revenue was approximately 50% higher when territorial user rights were enforced than when they were not. The model preferentially allocated area to the enforced-TURF zone over other zones, demonstrating that the financial benefits of enforcement (derived from higher species abundance) exceeded the costs. These findings were robust to increases in enforcement costs but sensitive to changes in species' market price. We also found that revenue under the existing zoning regime in the study area was 13-30% lower than under an optimal solution. Our results highlight the importance of accounting for both the benefits and costs of enforcement in marine conservation, particularly when incurred by fishers. © 2014 Society for Conservation Biology.

Creating New Technologists of Research in the 1960s: The Case of the Reproduction of Automated Chromatography Specialists and Practitioners

Science.gov (United States)

Gerontas, Apostolos

2014-08-01

Chromatographic instrumentation has been really influential in shaping the modern chemical practice, and yet it has been largely overlooked by history of science.Gas chromatography in the 1960s was considered the analytical technique closer to becoming dominant, and being the first automated chromatography set the standards that all the subsequent chromatographic instrumentation had to fulfill. Networks of specialists, groups of actors, corporate strategies and the analytical practice itself, were all affected and in many ways because of the entrance of gas chromatography in the chemical laboratory and in the instrumentation market. This paper gives a view of the early history of the gas chromatography instrumentation, relates it to the broader research-technology phenomenon and discusses issues of education and group reproduction in the case of the groups of technologists of the era. The chaotic elements of knowledge transfer during the instrumentation revolution in chemistry are being highlighted and they are being connected to the observable radical innovation of the period.

TH-C-18A-08: A Management Tool for CT Dose Monitoring, Analysis, and Protocol Review

Purpose: To develop a customizable tool for enterprise-wide managing of CT protocols and analyzing radiation dose information of CT exams for a variety of quality control applications Methods: All clinical CT protocols implemented on the 11 CT scanners at our institution were extracted in digital format. The original protocols had been preset by our CT management team. A commercial CT dose tracking software (DoseWatch,GE healthcare,WI) was used to collect exam information (exam date, patient age etc.), scanning parameters, and radiation doses for all CT exams. We developed a Matlab-based program (MathWorks,MA) with graphic user interface which allows to analyze the scanning protocols with the actual dose estimates, and compare the data to national (ACR,AAPM) and internal reference values for CT quality control. Results: The CT protocol review portion of our tool allows the user to look up the scanning and image reconstruction parameters of any protocol on any of the installed CT systems among about 120 protocols per scanner. In the dose analysis tool, dose information of all CT exams (from 05/2013 to 02/2014) was stratified on a protocol level, and within a protocol down to series level, i.e. each individual exposure event. This allows numerical and graphical review of dose information of any combination of scanner models, protocols and series. The key functions of the tool include: statistics of CTDI, DLP and SSDE, dose monitoring using user-set CTDI/DLP/SSDE thresholds, look-up of any CT exam dose data, and CT protocol review. Conclusion: our inhouse CT management tool provides radiologists, technologists and administration a first-hand near real-time enterprise-wide knowledge on CT dose levels of different exam types. Medical physicists use this tool to manage CT protocols, compare and optimize dose levels across different scanner models. It provides technologists feedback on CT scanning operation, and knowledge on important dose baselines and thresholds

To compare the incidence, severity and nature of injuries sustained by Saudi National Team footballers during match-play and training on natural grass and 3rd generation (3G) artificial turf. Injury data was collected on all Saudi National Team players competing at the Gulf Cup (Yemen December 2010: 3G) and the Asian Cup (Qatar January 2011; grass). A total of 49 players were studied (mean ± SD; Age 27 ± 4 yr; body mass 71.4 ± 6.7 kg; height 176.8 ± 6.3 cm; professional playing experience 9 ± 3 yr) of which 31 competed at the Gulf Cup, 32 at the Asian Cup (14 at both). A prospective cohort design was used to investigate the incidence, nature and severity of injuries sustained with data collected using a standardised injury questionnaire. All data were collected by the team physiotherapist with the definition of injury set at any injury that required player and clinician contact. Injury and exposure data were collected and reported for games, training and all football activity. A total of 82 injuries [incidence - 56.1 per 1000 h total game and training exposure] were recorded at the Asian Cup (grass) and 72 injuries [incidence - 37.9 per 1000 h total game and training exposure] were recorded at the Gulf Cup (3G). Incidence data for training, game and all football exposure injury rates were higher when playing on grass. The vast majority of injuries on both surfaces were very minor that, whilst requiring medical attention, did not result in loss of match/training exposure. Injuries that resulted in 1-3 days absence from training or game play had similar incidence rates (Grass: 7.4 vs. 3G: 7.4 injuries per 1000 h exposure). More severe injuries were less frequent but with a higher incidence when playing on grass. Lower limb injuries were the most common in both tournaments with a higher incidence on grass (Grass: 14.2 vs. 3G: 7.9 injuries per 1000 h exposure). Muscle injuries were the most frequent of all injuries with similar incidence rates on

A real-time monitoring study of the personal dose received by nuclear medicine technologists administering 18F-FDG in a high patient throughput PET centre

The rapid growth in PET studies has resulted in an increasing occupational radiation exposure to nuclear medicine staff. This project has used, a real-time, solid-state, 2 second resolution, personal dosimeter to monitor the occupational Hp(10) equivalent dose of nuclear medicine technologist (NMT) staff managing FDG patients. A detailed manual mapping of the patient management procedure, time dependence and distance relationships to the sources of exposure and their magnitudes was undertaken. Experimental results show, that a junior NMT may spend on average 52% of the close contact time (< 2 m) with the patient when administering an FDG dose compared to 36% of that time for the senior NMT. The average daily dose from isotope administration of a junior NMT and senior NMT is 15 μSv and 11.4 μSv respectively. Post-administration, escorting the patient into the scanner room and setting-up the patient on the PET scanner bed, takes approximately 27% of the junior NMT time to perform, which results in an average daily dose of 7.8 μSv. The senior NMT takes approximately 33% of their time for the same task, with an average daily dose of 10.3 μSv. Removing the patient from the scanner room and escorting them from the department takes about 21% of the junior NMT time giving 6.2 μSv of dose and 31% or 9.7 μSv for the senior NMT. At the conclusion of this study the typical daily dose received by NMT staff, working in close contact with FDG patients is approximately 29 μSv for junior NMT (4 - 5 mSv/yr) and 31.4 μSv (5 - 7 mSv/yr) for senior NMT. Currently this centre is performing approximately 3,400 FDG injections per year plus 50 research injections of various positron emitters. This occupational dose load is spread across 3 dedicated PET NMT staff and 1.5 EFT NMT staff rotating through PET centre from the nuclear medicine department and 1 EFT registrar physician. (author)

Four captive raptors, an American kestrel ( Falco sparverius ), peregrine falcon ( Falco peregrinus ), golden eagle ( Aquila chrysaetos ), and barn owl ( Tyto alba ), were diagnosed with ventricular and/or proventricular foreign material impactions consisting of artificial turf substrate, paper and plastic substrate, grass, and newspaper. Partial or total anorexia was reported in all birds and decreased casting in 2 birds. Survey radiographs confirmed presence of gastric enlargement in all 4 birds. The kestrel and eagle were treated unsuccessfully with gastroscopy and gastric lavage, respectively, followed by surgical intervention to remove the ventricular impactions. Both birds died of undetermined causes after surgery. The peregrine falcon died before medical or surgical intervention was started, and the owl was managed successfully with oral mineral oil and liquid diet to facilitate egestion of the foreign material as a pellet. Lead poisoning was suspected as the predisposing cause for foreign body ingestion in the eagle, but underlying causes for pica in the other birds were not determined. Radiographs can provide useful diagnostic information in sick raptors that exhibit vomiting or changes in appetite or casting frequency, and may help guide treatment decisions of impacted birds. Careful consideration of substrate, enrichment items, and access to potential foreign material that could be ingested may be the best pre-emptive management strategy in captive raptors.

Artificial structures will be increasingly utilized to protect coastal infrastructure from sea-level rise and storms associated with climate change. Although it is well documented that the materials comprising artificial structures influence the composition of organisms that use them as habitat, little is known about how these materials may chemically react with changing seawater conditions, and what effects this will have on associated biota. We investigated the effects of ocean warming, acidification, and type of coastal infrastructure material on algal turfs. Seawater acidification resulted in greater covers of turf, though this effect was counteracted by elevated temperatures. Concrete supported a greater cover of turf than granite or high-density polyethylene (HDPE) under all temperature and pH treatments, with the greatest covers occurring under simulated ocean acidification. Furthermore, photosynthetic efficiency under acidification was greater on concrete substratum compared to all other materials and treatment combinations. These results demonstrate the capacity to maximise ecological benefits whilst still meeting local management objectives when engineering coastal defense structures by selecting materials that are appropriate in an ocean change context. Therefore, mitigation efforts to offset impacts from sea-level rise and storms can also be engineered to alter, or even reduce, the effects of climatic change on biological assemblages.

We implemented an Image Quality Reporting and Tracking Solution (IQuaRTS), directly linked from the PACS, to improve communication between radiologists and technologists. IQuaRTS launched in May 2015. We compared MRI issues filed in the period before IQuaRTS implementation (May-September 2014) using a manual system with MRI issues filed in the IQuaRTS period (May-September 2015). The unpaired t test was used for analysis. For assessment of overall results in the IQuaRTS period alone, all issues filed across all modalities were included. Summary statistics and charts were generated using Excel and Tableau. For MRI issues, the number of issues filed during the IQuaRTS period was 498 (2.5% of overall MRI examination volume) compared with 78 issues filed during the period before IQuaRTS implementation (0.4% of total examination volume) (p = 0.0001), representing a 625% relative increase. Tickets that documented excellent work were 8%. Other issues included images not pushed to PACS (20%), film library issues (19%), and documentation or labeling (8%). Of the issues filed, 55% were MRI-related and 25% were CT-related. The issues were stratified across six sites within our institution. Staff requiring additional training could be readily identified, and 80% of the issues were resolved within 72 hours. IQuaRTS is a cost-effective online issue reporting tool that enables robust data collection and analytics to be incorporated into quality improvement programs. One limitation of the system is that it must be implemented in an environment where staff are receptive to quality improvement.

Full Text Available Frequent reports of laboratory- (and hospital- acquired infection suggest a deficiency in safety training or lack of compliance. To assess the need for continuing education (CE addressing this problem, an original education needs assessment survey was designed and administered to medical technologists (med-techs in Northeast Ohio. Survey results were used to design a learner-centered training curriculum (for example, Lab Safety and Bioterrorism Readiness trainings that engaged med-techs in active learning, integrative peer-to-peer teaching, and hands-on exercises in order to improve microbiology safety knowledge and associated laboratory techniques. The Lab Safety training was delivered six times and the Bioterrorism Readiness training was delivered five times. Pre/posttesting revealed significant gains in knowledge and techniques specific to laboratory safety, security, risk assessment, and bioterrorism readiness amongst the majority of med-techs completing the CE trainings. The majority of participants felt that the hands-on exercises met their needs and that their personal laboratory practices would change as a result of the training course, as measured by attitudinal surveys. We conclude that active learning techniques and peer education significantly enhance microbiology learning amongst participating med-techs.

This study aimed to assess whether the changes in compliance rates of evaluation criteria after healthcare accreditation among radiologic technologists working at four university hospitals which had acquired healthcare accreditation in Daejeon metropolitan area. In this study, the evaluation criteria of healthcare accreditation were reclassified and reevaluated to three areas which include patient safety, staff safety, and environmental safety. Each area has eight, three, and five questions, respectively. Each compliance rate was quantitatively measured on a scale of 0 to 10 before and after in this study. The result shows that the overall compliance rates were decreased on all areas compared to the time healthcare accreditation was obtained. The compliance rate of hand hygiene was drastically reduced. To maintain the compliance rates, not only individuals but healthcare organizations should simultaneously endeavor. In particular, healthcare organizations should make an effort to provide continuous education opportunity to their workers and supervise the compliance regularly

Distribution, behavior, and condition of herbivorous fishes on coral reefs track algal resources.

2016-05-01

Herbivore distribution can impact community structure and ecosystem function. On coral reefs, herbivores are thought to play an important role in promoting coral dominance, but how they are distributed relative to algae is not well known. Here, we evaluated whether the distribution, behavior, and condition of herbivorous fishes correlated with algal resource availability at six sites in the back reef environment of Moorea, French Polynesia. Specifically, we tested the hypotheses that increased algal turf availability would coincide with (1) increased biomass, (2) altered foraging behavior, and (3) increased energy reserves of herbivorous fishes. Fish biomass and algal cover were visually estimated along underwater transects; behavior of herbivorous fishes was quantified by observations of focal individuals; fish were collected to assess their condition; and algal turf production rates were measured on standardized tiles. The best predictor of herbivorous fish biomass was algal turf production, with fish biomass increasing with algal production. Biomass of herbivorous fishes was also negatively related to sea urchin density, suggesting competition for limited resources. Regression models including both algal turf production and urchin density explained 94 % of the variation in herbivorous fish biomass among sites spread over ~20 km. Behavioral observations of the parrotfish Chlorurus sordidus revealed that foraging area increased as algal turf cover decreased. Additionally, energy reserves increased with algal turf production, but declined with herbivorous fish density, implying that algal turf is a limited resource for this species. Our findings support the hypothesis that herbivorous fishes can spatially track algal resources on coral reefs.

2018-03-01

Due to the high concern generated in the last years about the safety of recycled tire rubber used for recreational sports surfaces, this study aims at evaluating the presence of forty organic compounds including polycyclic aromatic hydrocarbons (PAHs), phthalates, adipates, vulcanisation additives and antioxidants in recycled tire crumb of synthetic turf football fields. Ultrasound Assisted Extraction (UAE) was successfully employed to extract the target compounds from the crumb rubber, and analysis was performed by gas chromatography-mass spectrometry (GC-MS). The transfer of the target chemicals from the crumb rubber to the runoff water and to the air above the rubber surface has also been evaluated employing solid-phase microextraction (SPME). Samples from fifteen football fields were analysed, and the results revealed the presence of 24 of the 40 target compounds, including 14 of the 16 EPA PAHs, with total concentrations up to 50 μg g -1 . Heavy metals such as Cd, Cr and Pb were also found. A partial transfer of organic compounds to the air and runoff water was also demonstrated. The analysis of rain water collected directly from the football field, showed the presence of a high number of the target compounds at concentrations reaching above 100 μg L -1 . The environmental risk arising from the burning of crumb rubber tires has been assessed, as well, analysing the crumb rubber, and the air and water in contact with this material, showing a substantial increase both of the number and concentration of the hazardous chemicals.

Although the implementation of picture archiving and communication system (PACS) could increase productivity of radiology departments, this depends on factors such as the PACS competence of radiologic technologists (RTs). The purpose of this study was to investigate the RTs' perceptions of PACS competence and educational issues in Western Australia (WA). A hardcopy questionnaire was distributed to WA RTs for obtaining their perceptions of PACS competence and educational issues. Descriptive (percentage of frequency, mean and standard deviation) and inferential statistics (t test and analysis of variance) were used to analyze the responses of the multiple choice and five-point scale questions from the returned questionnaires. The questionnaire response rate was 57.7% (173 out of 300). The mean values of all PACS competence questions except questions 2e-g are in the range of 3.9-4.9, i.e., around competent to very competent. Participants indicated they received adequate PACS training (mean 3.8). Statistically significant variables influencing RTs' perceptions of their PACS competence and educational issues including the age (p education received (p system, and received adequate training. However, future PACS education programs should be tailored to different RTs' groups. For example, multiple training modules might be necessary to support the PACS competence development of older RTs and those with lower general computer literacy.

A view on risk management

International Nuclear Information System (INIS)

Joksimovich, V.

1991-01-01

The world at large has enjoyed the benefits of industrial technology for almost two centuries. The managers of industrial facilities as well as members of the public focused on the benefits and typically ignored or underestimated the inherent risks entailed in deployment of these technologies. Two examples will be given for the sake of illustration. In the chemical industry, the impacts of various chemicals on humans are insufficiently understood. In addition, it was not even known that some hazardous chemicals could be formed in the chemical reactions taking place in various chemical reactors. This is equivalent to not knowing that Cesium-iodide compound can be formed within nuclear fuel nor the impact it might have on humans if released, which is inconceivable in the nuclear industry. In the era of risk recognition, many industrial managers proclaimed that safety is everybody's business. The basic premise behind this was that since everyone is responsible, no one can be blamed for accidents. This is, however, shifting because both economics and litigation are now compelling industrial managers to consider risk in conjunction with the benefit. The government managers in many cases interpreted their charter to reap benefits first and pay the price of risks later; e.g., the case of nuclear weapons production facilities seriously contaminated by radioactive and other hazardous materials. Cost of clean-up was estimated at more than $100 billion. Of course, the authors have similar examples in many other industries, e.g., Superfund project of chemical waste sites. The challenge for the technologists is to maximize the benefit/risk ratio, keeping the risks, real or perceived, acceptably small. This brings us to the issue of acceptable risks, the topic of this paper

Aim: The use of PACS and the need for images and clinical data is increasing exponentially. This presentation will provide a historical overview of radiology information systems (RIS) and their interaction with hospital information systems (HIS), PACS systems and modalities. Materials and Methods: The various approaches to interfacing and integrating RIS and PACS systems will be described as well as their impact on radiology departmental work-flow and the productivity of radiologists, technologists and other RIS users. Specifically, the image-centric and RIS-centric approaches to PACS will be compared. Results: Instant access to vital clinical information enables radiology departments to go beyond simply managing processes to making fundamental improvements in productivity and care processes. Unity of design translates into simplicity of operations. Integration of historically separate applications makes the environment easier to support, reduces turnaround time, and improves patient care. Conclusion: Finally, insight on new technologies and future trends in PACS, system integration and work-flow strategies will be presented in light of delivery of both clinical images and clinical data

Emergence of collective action and environmental networking in relation to radioactive waste management

International Nuclear Information System (INIS)

Williams, R.G.; Payne, B.A.

1985-01-01

This paper explores the relationship between the national environmental movement and nuclear technology in relation to a local emergent group. The historical development of nuclear technology in this conutry has followed a path leading to continued fear and mistrust of waste management by a portion of the population. At the forefront of opposition to nuclear technology are people and groups endorsing environmental values. Because of the antinuclear attitudes of environmentalists and the value orientation of appropriate technologists in the national environmental movement, it seems appropriate for local groups to call on these national groups for assistance regarding nuclear-related issues. A case study is used to illustrate how a local action group, once integrated into a national environmental network, can become an effective, legitimate participant in social change. The formation, emergence, mobilization, and networking of a local group opposed to a specific federal radioactive waste management plan is described based on organizational literature. However, inherent contradictions in defining the local versus national benefits plus inherent problems within the environmental movement could be acting to limit the effectiveness of such networks. 49 refs

Improper handling of medical wastes, which is common in Bangladesh, could adversely affect the hospital environment and community at large, and poses a serious threat to public health. We aimed to assess the knowledge and practices regarding medical waste management (MWM) among healthcare providers (HCPs) and to identify possible barriers related to it. A cross-sectional study was carried out during June to September, 2012 including 1 tertiary, 3 secondary, and 3 primary level hospitals in Dhaka division, Bangladesh through 2-stage cluster sampling. Data were collected from 625 HCPs, including 245 medical doctors, 220 nurses, 44 technologists, and 116 cleaning staff who were directly involved in MWM using a self-administered (researcher-administered for cleaning staff), semi-structured questionnaire. Nearly one-third of medical doctors and nurses and two-thirds of technologists and cleaning staff had inadequate knowledge, and about half of medical doctors (44.0%) and cleaning staff (56.0%) had poor practices. HCPs without prior training on MWM were more likely to have poor practices compared to those who had training. Lack of personal protective equipment, equipment for final disposal, MWM-related staff, proper policy/guideline, and lack of incinerator were identified as the top 5 barriers. Strengthening and expansion of ongoing educational programs/training is necessary to improve knowledge and practices regarding MWM. The government should take necessary steps and provide financial support to eliminate the possible barriers related to proper MWM.

Incorporation of organic fertilizers/amendments has been, and continues to be, a popular strategy for golf course turfgrass management. Dissolved organic matter (DOM) derived from these organic materials may, however, facilitate organic chemical movement through soils. A batch equilibrium technique was used to evaluate the effects of organic fertilizer-derived DOM on sorption of three organic chemicals (2,4-D, naphthalene and chlorpyrifos) in USGA (United States Golf Association) sand, a mixed soil (70% USGA sand and 30% native soil) and a silt loam soil (Typic Fragiochrept). DOM was extracted from two commercial organic fertilizers. Column leaching experiments were also performed using USGA sand. Sorption experiments showed that sorption capacity was significantly reduced with increasing DOM concentration in solution for all three chemicals. Column experimental results were consistent with batch equilibrium data. These results suggest that organic fertilizer-derived DOM might lead to enhanced transport of applied chemicals in turf soils. - Dissolved organic matter could result in enhanced transport of chemicals applied to turf.

A synoptic view of golf course management

Katula, Robert L.

1996-03-01

The maintenance, construction, and redesign of private, public, and municipal golf courses in the United States is a multi-billion dollar industry. The entire golf course maintenance market, according to the National Golf Foundation, was 6.2 billion per year in 1991. The average maintenance cost in the United States was approximately 40,000 per hole per year for the over 15,000 golf courses in the United States in 1991. Golf course maintenance costs have risen 500 percent from 1971 to 1991. These costs are projected to continue to increase at a rate of 8 percent per year due to the demand for quality playing surfaces, increased use of non-potable water, and taxes on water and chemicals required to maintain turfgrass. The golf course construction and redesign market continues to maintain a rate of over 300 new golf courses and redesigned courses completed each year. The average construction costs run from 4 to 6 million and the average redesign costs 2 to 3 million per course. In order to create a perfectly maintained golf course, golf course managers may use as many as 25 different pesticides, fertilizers, and herbicides to control insects and turf disease. Further, turfgrass is often stressed to its limits when kept at the unnatural heights required to obtain firm and fast greens and fairways. The daily practice of living on the edge is often done with limited knowledge of changes taking place on the golf course, of the location of soil types and fertility, of surface and subsurface drainage, and of previous maintenance practices. There is a growing concern in the golf course industry that the concentration of chemicals and water required to maintain today's golf course may endanger ground water supplies for the surrounding ecosystem. This paper will describe the general methodology PTS used to develop a new management system for the maintenance, construction, and redesign of golf courses. The management system integrates remote sensing technology, geographic

Full Text Available The implementation of a knowledge management program in an organization has the potential of im-proving customer services, quickly bringing new products to market, and reducing cost of business operations. Information technologies are often used in knowledge management programs in informing clients and employees of latest innovation/development in the business sector as well as sharing knowledge among the employees. The key professionals involved in knowledge management programs are information technologists and human resource managers but the information professionals also have a role to play as they are traditionally known as good managers of explicit knowledge. Hence, the aim of this study is to provide empirical evidence of the role of information professionals in knowledge management programs. 386 information professionals working in Canadian organizations were selected from the Special Libraries Association's Who's Who in Special Libraries 2001/2002, and a questionnaire with a stamped self-addressed envelope for its return was sent to each one of them. 63 questionnaires were completed and returned, and 8 in-depth interviews conducted. About 59% of the information professionals surveyed are working in organizations that have knowledge management programs with about 86% of these professionals being involved in the programs. Factors such as gender, age, and educational background (i.e. highest educational qualifications and discipline did not seem to have any relationship with involvement in knowledge management programs. Many of those involved in the programs are playing key roles, such as the design of the information architecture, development of taxonomy, or con-tent management of the organization's intranet. Others play lesser roles, such as providing information for the intranet, gathering competitive intelligence, or providing research services as requested by the knowledge management team.

Full Text Available The aim of this work was to evaluate the survival and the initial growth of mycorrhizated eucalypts with Pisolithus microcarpus (UFSC Pt 116 ectomycorrhizal fungus, after its transplant to area subject to the arenization process in São Francisco de Assis, RS. The area was divided into four blocks, each one with four treatments (fertile turf with and without mycorrhizae, Quartzarenic Neosoil with and without mycorrhizae. Each parcel was composed of 16 seedlings arranged in four lines in the spacing of 1,5 m x 1,5 m, totalizing in each block 64 seedlings. 90 days after the planting in the field, the eucaliptus seedlings produced in turf with fungus in the fertile substratum presented a survival rate of 100 %, whereas for those produced in fertile turf without fingi, the survival rate was 92 %. The seedlings produced in the Quartzarenic Neosoil with and without mycorrhizae had a survival rate varying around 98 and 89 %, respectively. The produced seedlings with turf and fungus showed significant differences in height and stem diameter. This study showed that the Eucalyptus grandis seedlings produced in substratum fertile turf and inoculated with the Pisolithus microcarpus (UFSC Pt 116 isolated may maintain good development and establishment in the field.

Full text: To describe technologist perspective of working with ultra fast solid state gamma camera and comparison with conventional dual head gamma camera. Material and Methods: 900 Myocardial Perfusion scan were carried out on dedicated solid state detector cardiac camera between 1st February 2010 till 29th August 2010. 27 studies were done back to back on a conventional dual head gamma camera. In 2 cases dual head isotope imaging was done (Thallium+ 99m Tc-tetrofosmin). Rest stress protocol was used in 600 patients and stress - rest protocol was used in 300. 1:3 ratio of injected activity was maintained for both protocols (5 mCi for 1st study and 15 mCi for second study). For Rest - Stress protocol, 5 mCi of 99m Tc - Tetrofosmin was injected at rest, 40 minutes later, 5 min image was acquired on the solid state detector. Patient was then stressed. 15 mCi 99m Tc - Tetrofosmin was injected at peak stress. Images were acquired 20 minutes later for 3 minutes (total duration of study 90-100 min). For stress rest protocol, 5 mCi 99m Tc - Tetrofosmin was injected at peak stress. 5 mCi images were acquired 20 minutes later. Rest injection of 15 mCi was given 1 hour post stress injection. Rest images were acquired 40 minutes after rest injection (total duration of study 110-120 min). Results: We observed even with lesser amount activity and acquisition time of 5 min/cardiac scan it showed high sensitivity count rate over 2.2-4.7 kcps (10 times more counts than standard gamma camera). System gives better energy resolution < 7%. Better image contrast. Dual isotope imaging can be possible. Spatial resolution 4.3-4.9 mm. Excellent quality images were obtained using low activities (5 mCi/15 mCi) using 1/3rd the acquisition time compared to conventional dual head gamma camera Even in obese patients 7 mCi/21 mCi activity yielded excellent images at 1/3 rd acquisition time Quick acquisition resulted in greater patient comfort and no motion artifact also due to non rotation of

Soil structure and moisture, thermal conditions and vegetation control solifluction movement, however, the spatial distribution of controlling factors and resultant spatial variability of movement are poorly understood. We use a (1) geomorphological and vegetation mapping of solifluction lobe properties, (2) temperature loggers to quantify thermal conditions, (3) 2D Electrical Resistivity Tomography (ERT), Puerkhauer drilling and TDR measurements to evaluate material properties as well as (4) 3D Time-Lapse ERT to quantify spatial variability of material properties. Our results are used to (5) evaluate the influence of potential controlling factors on solifluction movement. Investigations took place on three turf-banked lobes (TBL) located at proximal and distal slopes of Little Ice Age and 1920s lateral moraines in the Turtmann glacier forefield, Swiss Alps. (1) Vegetation is spatially differentiated at TBLs. The treads are mostly covered by the ecosystem engineer Dryas octopetala, while other dwarf shrubs, shrubs and pioneer species were found at the high lobe risers (0.8-1.8 m). In contrast, less vegetated ridge-like features at the upper part of the treads are colonized by frost-tolerant species. Large blocks are located at the lobe fronts, probably impeding the lobe movement. (2) Temperature loggers show a lack of ground cooling due to snow isolation at the vegetated lower tread between 2014 and 2015. Thus, significant ground cooling in winter is reduced to the wind-exposed upper parts (ridges). (3) TBL material consists of sandy silt, thus, lobe material is much finer than subjacent moraine till and indicates former colluviation. As a consequence, 2D ERT demonstrates low-resistant areas until depths equal to riser height, thus, the finer TBL body is higher saturated than the coarser surrounding parent slope and more susceptible to gelifluction. On the contrary, risers show high resistivities indicating dry conditions which are supported by TDR results

In order to prevent food safety incidents from becoming a crisis, a good crisis management structure is essential. The aim of the current study was to compare and evaluate the national food incident response plans of 2 neighboring EU Member States: Germany and the Netherlands. This revealed that the structure of these plans is comparable, starting with initial alerting, assessment of the problem, upscaling, an execution phase and finally an evaluation of the crisis management. However, the German communication structure is more complex than the Dutch one and cross-border communication between both countries is currently limited. In general, the presence of national response plans does not guarantee a good and swift response to a food safety incident as this is often hampered by difficulties in tracing the source of the problem as well as difficulties in communication between organizations involved in crisis management. A timely detection can be improved through the development of fast screening and detecting systems and through combining various data sources using computer software systems. Mutual cooperation and communication can be improved through joint exercises or projects. This will help to streamline communication toward consumers and trade partners. Such communication should be transparent relaying not only the facts but also the uncertainties in a crisis in order to gain consumer trust and safeguard international trade. © 2017 Institute of Food Technologists®.

The current state of health of the coral reefs in the northern Gulf of Aqaba (Red Sea), notably the Eilat reefs, is under debate regarding both their exact condition and the causes of degradation. A dearth of earlier data and unequivocal reliable indices are the major problems hinder a clear understanding of the reef state. Our research objective was to examine coral-algal dynamics as a potential cause and an indication of reef degradation. The community structure of stony corals and algae along the northern Gulf of Aqaba reveal non-seasonal turf algae dominancy in the shallow Eilat reefs (up to 72%), while the proximate Aqaba reefs present negligible turf cover (<6%). We believe that turf dominancy can indicate degradation in these reefs, based on the reduction in essential reef components followed by proliferation of perennial turf algae. Our findings provide further evidence for the severe state of the Eilat coral reefs.

Full Text Available Background: It is of critical importance to improve and maintain the quality of chest radiography (CXR to avoid faulty diagnosis of respiratory diseases. The study aims to determine the effectiveness of a training program in improving the quality of CXR among radiological technologists (RTs in Laos. Design: This was a cross-sectional study, conducted through on-site investigation of X-ray facilities, assessment of CXR films in Laos, both before and after a training course in November 2013. Methods: Each RT prospectively selected 6 recent CXR films, taken both before and within approximately 6 months of attending the training course. Consequently, 12 CXR films per RT were supposed to be collected for assessment. The quality of the CXR films was assessed using the “Assessment Sheet for Imaging Quality of Chest Radiography.” Results: Nineteen RTs from 19 facilities at 16 provinces in Laos participated in the training course. Among them, 17 RTs submitted the required set of CXR films (total: 204 films. A wide range of X-ray machine settings had been used as tube voltage ranged from 40 to 130 kV. The assessment of the CXR films indicated that the training was effective in improving the CXR quality regarding contrast (P = 0.005, sharpness (P = 0.004, and the total score on the 6 assessment factors (P = 0.009. Conclusions: The significant improvement in the total score on the 6 assessment factors, in contrast, and in sharpness, strongly suggests that the training course had a positive impact on the quality of CXR among a sample trainees of RTs in Laos.

Statistics Refresher for Molecular Imaging Technologists, Part 2: Accuracy of Interpretation, Significance, and Variance.

Science.gov (United States)

Farrell, Mary Beth

2018-06-01

This article is the second part of a continuing education series reviewing basic statistics that nuclear medicine and molecular imaging technologists should understand. In this article, the statistics for evaluating interpretation accuracy, significance, and variance are discussed. Throughout the article, actual statistics are pulled from the published literature. We begin by explaining 2 methods for quantifying interpretive accuracy: interreader and intrareader reliability. Agreement among readers can be expressed simply as a percentage. However, the Cohen κ-statistic is a more robust measure of agreement that accounts for chance. The higher the κ-statistic is, the higher is the agreement between readers. When 3 or more readers are being compared, the Fleiss κ-statistic is used. Significance testing determines whether the difference between 2 conditions or interventions is meaningful. Statistical significance is usually expressed using a number called a probability ( P ) value. Calculation of P value is beyond the scope of this review. However, knowing how to interpret P values is important for understanding the scientific literature. Generally, a P value of less than 0.05 is considered significant and indicates that the results of the experiment are due to more than just chance. Variance, standard deviation (SD), confidence interval, and standard error (SE) explain the dispersion of data around a mean of a sample drawn from a population. SD is commonly reported in the literature. A small SD indicates that there is not much variation in the sample data. Many biologic measurements fall into what is referred to as a normal distribution taking the shape of a bell curve. In a normal distribution, 68% of the data will fall within 1 SD, 95% will fall within 2 SDs, and 99.7% will fall within 3 SDs. Confidence interval defines the range of possible values within which the population parameter is likely to lie and gives an idea of the precision of the statistic being

The global decline of canopy-forming macroalgae has stimulated research on the mechanism regulating shifts among alternative habitats on rocky reefs. The effects of sea urchin grazing and alterations of environmental conditions are now acknowledged as the main drivers of shifts between canopy-formers and encrusting coralline barrens and algal turfs, respectively. The conditions under which these mechanisms operate remains, however, somewhat elusive. This is mostly a consequence of the fact that our current understanding has been generated by envisioning habitat shifts as dichotomic, at odds with rocky reef landscapes being composed by mosaics of habitats and with evidence of strong interactions among the species that compose each of the alternative habitats. Using data from a long-term sampling program and path analysis, we investigated how wave-exposure and human-induced degradation of environmental conditions regulate the mechanisms maintaining algal canopies formed by Cystoseira crinita, barren habitats and algal turfs as alternative states on subtidal reefs in the NW Mediterranean. In the Tuscan Archipelago, wave-exposure had positive effects on sea urchins, which, likely due to their low mean density, had weak effects on each of the alternative habitats. Canopy-forming macroalgae resulted, instead, to exert strong negative effects on the abundance of algal turfs. Since data from the Tuscan Archipelago did not explain any of the variation in the abundance of C. crinita canopies, a further analysis was performed including data from the coast of Tuscany to assess the role of cumulative human impacts in regulating habitat shifts. This showed that degradation of environmental conditions is a direct cause of the decline of macroalgal canopies, indirectly favouring the dominance of algal turfs. Our study suggests that management of human impacts should be considered a priority for preserving subtidal canopies formed by Cystoseira in the NW Mediterranean and that

DeLiberto, Shelagh T; Werner, Scott J

2016-10-01

We have reviewed published anthraquinone applications for international pest management and agricultural crop protection from 1943 to 2016. Anthraquinone (AQ) is commonly found in dyes, pigments and many plants and organisms. Avian repellent research with AQ began in the 1940s. In the context of pest management, AQ is currently used as a chemical repellent, perch deterrent, insecticide and feeding deterrent in many wild birds, and in some mammals, insects and fishes. Criteria for evaluation of effective chemical repellents include efficacy, potential for wildlife hazards, phytotoxicity and environmental persistence. As a biopesticide, AQ often meets these criteria of efficacy for the non-lethal management of agricultural depredation caused by wildlife. We summarize published applications of AQ for the protection of newly planted and maturing crops from pest birds. Conventional applications of AQ-based repellents include preplant seed treatments [e.g. corn (Zea mays L.), rice (Oryza sativa L.), sunflower (Helianthus annuus L.), wheat (Triticum spp.), millet (Panicum spp.), sorghum (Sorghum bicolor L.), pelletized feed and forest tree species] and foliar applications for rice, sunflower, lettuce (Lactuca sativa L.), turf, sugar beets (Beta vulgaris L.), soybean (Glycine max L.), sweet corn and nursery, fruit and nut crops. In addition to agricultural repellent applications, AQ has also been used to treat toxicants for the protection of non-target birds. Few studies have demonstrated AQ repellency in mammals, including wild boar (Sus scrofa, L.), thirteen-lined ground squirrels (Ictidomys tridecemlineatus, Mitchill), black-tailed prairie dogs (Cyomys ludovicainus, Ord.), common voles (Microtus arvalis, Pallas), house mice (Mus musculus, L.), Tristram's jirds (Meriones tristrami, Thomas) and black rats (Rattus rattus L.). Natural sources of AQ and its derivatives have also been identified as insecticides and insect repellents. As a natural or synthetic biopesticide, AQ

Turfgrass species composition, resistance mechanisms, and management strategy impacts on brown patch incidence and weed encroachment

Tall fescue (Festuca arundinacea Schreb.) has great utility as a low maintenance turfgrass in the northern and transition zone regions of the United States. However, it is difficult to successfully maintain tall fescue of high quality over consecutive summers because of its susceptibility to the fungal pathogen Rhizoctonia solani, which causes the disease brown patch. Not only is brown patch aesthetically unpleasing in a stand of tall fescue but it can also thin out the turf and allow for th...

Stability of strong species interactions resist the synergistic effects of local and global pollution in kelp forests.

Directory of Open Access Journals (Sweden)

Laura J Falkenberg

Full Text Available Foundation species, such as kelp, exert disproportionately strong community effects and persist, in part, by dominating taxa that inhibit their regeneration. Human activities which benefit their competitors, however, may reduce stability of communities, increasing the probability of phase-shifts. We tested whether a foundation species (kelp would continue to inhibit a key competitor (turf-forming algae under moderately increased local (nutrient and near-future forecasted global pollution (CO(2. Our results reveal that in the absence of kelp, local and global pollutants combined to cause the greatest cover and mass of turfs, a synergistic response whereby turfs increased more than would be predicted by adding the independent effects of treatments (kelp absence, elevated nutrients, forecasted CO(2. The positive effects of nutrient and CO(2 enrichment on turfs were, however, inhibited by the presence of kelp, indicating the competitive effect of kelp was stronger than synergistic effects of moderate enrichment of local and global pollutants. Quantification of physicochemical parameters within experimental mesocosms suggests turf inhibition was likely due to an effect of kelp on physical (i.e. shading rather than chemical conditions. Such results indicate that while forecasted climates may increase the probability of phase-shifts, maintenance of intact populations of foundation species could enable the continued strength of interactions and persistence of communities.

Urban green spaces are appreciated for their amenity value, with increasing interest in the ecosystem services they could provide (e.g. climate amelioration and increasingly as possible sites for carbon sequestration). In Singapore, turfgrass occupies approximately 20% of the total land area and is readily found on both planned and residual spaces. This project aims at understanding carbon fluxes in tropical urban green areas, including controls of soil environmental factors and the effect of urban management techniques. Given the large pool of potentially labile carbon, management regimes are recognised to have an influence on soil environmental factors (temperature and moisture), this would affect soil respiration and feedbacks to the greenhouse effect. A modified closed dynamic chamber method was employed to measure total soil respiration fluxes. In addition to soil respiration rates, environmental factors such as soil moisture and temperature, and ambient air temperature were monitored for the site in an attempt to evaluate their control on the observed fluxes. Measurements of soil-atmosphere CO2 exchanges are reported for four experimental plots within the Singtel-Kranji Radio Transmission Station (103o43'49E, 1o25'53N), an area dominated by Axonopus compressus. Different treatments such as the removal of turf, and application of clippings were effected as a means to determine the fluxes from the various components (respiration of soil and turf, and decomposition of clippings), and to explore the effects of human intervention on observed effluxes. The soil surface CO2 fluxes observed during the daylight hours ranges from 2.835 + 0.772 umol m-2 s-1 for the bare plot as compared to 6.654 + 1.134 umol m-2 s-1 for the turfed plot; this could be attributed to both autotrophic and heterotrophic respiration. Strong controls of both soil temperature and soil moisture are observed on measured soil fluxes. On the base soils, fluxes were positively correlated to soil

Requirements in the Overseas Employment and Domestic Connected Education for Radiological Technologists : Refers to Students Enrolled in the Department of Radiation

This study investigated the realities of information acquirements and its requirements in the overseas employment and domestic connected education for students at the department of radiation in order to provide basic information for developing the standard educational curriculum for future internationalization in the education of radiation and presenting its direction. The investigation implemented in this study was performed through a questionnaire with 688 students enrolled in the department of radiation. The conclusion of the investigation is summarized as follows : The answers for the question of 'No acquirements in the information of the overseas employment and connected education for radiological technologists' were 487 students (70.8%), and the reason that 'There are no chances in related education' was the highest rate, 424 students (61.6%), of the answers. In the education for the overseas employment, the answers for the question of 'Select a connected education program in school instead of study abroad' were the highest rate, 436 students (63.4%). The most concerned country for the overseas employment was 'Australia', 247 students (35.9%). As a result, answers for the interest, participation, need, and hope for the overseas employment showed high rates even though they demonstrated a low recognition level in the overseas employment. In addition, it is necessary to strategically plan an education program for this issue because all participants agree with the current stream.

In this study, a questionnaire survey was carried out to determine the actual situation of radiation safety management systems in Japanese medical institutions with nuclear medicine facilities. The questionnaire consisted of questions concerning the Radiation Protection Supervisor license, safety management organizations, and problems related to education and training in safety management. Analysis was conducted according to region, type of establishment, and number of beds. The overall response rate was 60%, and no significant difference in response rate was found among regions. Medical institutions that performed nuclear medicine practices without a radiologist participating accounted for 10% of the total. Medical institutions where nurses gave patients intravenous injections of radiopharmaceuticals as part of the nuclear medicine practices accounted for 28% of the total. Of these medical institutions, 59% provided education and training in safety management for nurses. The rate of acquisition of Radiation Protection Supervisor licenses was approximately 70% for radiological technologists and approximately 20% for physicians (regional difference, p=0.02). The rate of medical institutions with safety management organizations was 71% of the total. Among the medical institutions (n=208) without safety management organizations, approximately 56% had 300 beds or fewer. In addition, it became clear that 35% of quasi-public organizations and 44% of private organizations did not provide education and training in safety management (p<0.001, according to establishment).

Attitudes of the public about nuclear wastes

Rankin, W.L.; Nealey, S.M.

The disposal of nuclear wastes has become an important public issue in the past few years. In 1960, only a very small percentage of the American public questioned the safety of waste disposal methods, and no one opposed nuclear power for waste disposal reasons. By 1974, however, a slight majority of the public believed that the disposal of nuclear wastes was a serious problem associated with nuclear power, and from 1975 on, a small percentage of the public has opposed nuclear power for waste disposal reasons. More individuals believe that the technology is not available for acceptable waste management compared to the number of individuals who believe that the technology does exist. However, a majority of the public believe that modern technology can solve the waste disposal problem. Finally, nuclear technologists evaluate waste disposal problems differently from other groups. For instance, nuclear technologists believe that short-term safety is more important than long-term safety regarding waste disposal, while other groups, especially environmentalists, believe that long-term safety is more important than short-term safety. Nuclear technologists are willing to accept a higher level of waste management-related risk than other groups and evaluate waste disposal problems as being less severe than other societal problems

Since the care of patients with multiple chronic diseases such as diabetes and depression accounts for the majority of health care costs, effective team approaches to managing such complex care in primary care are needed, particularly since psychosocial and physical disorders coexist. Uncontrolled diabetes is a leading health risk for morbidity, disability and premature mortality with between 18-31% of patients also having undiagnosed or undertreated depression. Here we describe a team driven approach that initially focused on patients with poorly controlled diabetes (A1c > 9) that took place at a family medicare office. The team included: resident and faculty physicians, a pharmacist, social worker, nurses, behavioral medicine interns, office scheduler, and an information technologist. The team developed immediate integrative care for diabetic patients during routine office visits.

MRI protocols are instruction sheets that radiology technologists use in routine clinical practice for guidance (e.g., slice position, acquisition parameters etc.). In Mayo Clinic Arizona (MCA), there are over 900 MR protocols (ranging across neuro, body, cardiac, breast etc.) which makes maintaining and updating the protocol instructions a labor intensive effort. The task is even more challenging given different vendors (Siemens, GE etc.). This is a universal problem faced by all the hospitals and/or medical research institutions. To increase the efficiency of the MR practice, we designed and implemented a web-based platform (eProtocol) to automate the management of MRI protocols. It is built upon a database that automatically extracts protocol information from DICOM compliant images and provides a user-friendly interface to the technologists to create, edit and update the protocols. Advanced operations such as protocol migrations from scanner to scanner and capability to upload Multimedia content were also implemented. To the best of our knowledge, eProtocol is the first MR protocol automated management tool used clinically. It is expected that this platform will significantly improve the radiology operations efficiency including better image quality and exam consistency, fewer repeat examinations and less acquisition errors. These protocols instructions will be readily available to the technologists during scans. In addition, this web-based platform can be extended to other imaging modalities such as CT, Mammography, and Interventional Radiology and different vendors for imaging protocol management.

The Improvement Plan on Unifying from Law and Regulations Related to Radiation

This is for the purpose to help the bill related to technologists be systematic and unitary by carefully analyzing a legislation, an enforcement ordinance, and enforcement regulations in the connection with the radiological worker and the radiation workers from the law and regulations related to technologists. Concerning technologists, a legislation, an enforcement ordinance, and enforcement regulations for a sort of medical technician, regarding the radiological worker, the rules of diagnosis radiation equipment safety management, and concerning the radiation workers, atomic energy law, an enforcement ordinance and enforcement regulations were gathered, compared with one another, and analyzed. Among technologists, in the case of working in the department of diagnosis radiation, the title 'Radiological Worker' is used by the Medical Service Law, and in the case of working in the department of radiation tumors or the one of nucleus medicine, the title 'Radiation Workers' is used by the Atomic Energy Law. Besides the technical term that is used by characteristic tasks, unification of the terms that can be used in common is necessary for sure. And when a legislation, an enforcement ordinance, enforcement regulations, and notification, things like that in the radiation field are amended, certainly they should be done by mutual agreement through negotiation between the organization related to radiation and the governmental organization.

Coding for effective denial management.

Science.gov (United States)

Miller, Jackie; Lineberry, Joe

2004-01-01

Nearly everyone will agree that accurate and consistent coding of diagnoses and procedures is the cornerstone for operating a compliant practice. The CPT or HCPCS procedure code tells the payor what service was performed and also (in most cases) determines the amount of payment. The ICD-9-CM diagnosis code, on the other hand, tells the payor why the service was performed. If the diagnosis code does not meet the payor's criteria for medical necessity, all payment for the service will be denied. Implementation of an effective denial management program can help "stop the bleeding." Denial management is a comprehensive process that works in two ways. First, it evaluates the cause of denials and takes steps to prevent them. Second, denial management creates specific procedures for refiling or appealing claims that are initially denied. Accurate, consistent and compliant coding is key to both of these functions. The process of proactively managing claim denials also reveals a practice's administrative strengths and weaknesses, enabling radiology business managers to streamline processes, eliminate duplicated efforts and shift a larger proportion of the staff's focus from paperwork to servicing patients--all of which are sure to enhance operations and improve practice management and office morale. Accurate coding requires a program of ongoing training and education in both CPT and ICD-9-CM coding. Radiology business managers must make education a top priority for their coding staff. Front office staff, technologists and radiologists should also be familiar with the types of information needed for accurate coding. A good staff training program will also cover the proper use of Advance Beneficiary Notices (ABNs). Registration and coding staff should understand how to determine whether the patient's clinical history meets criteria for Medicare coverage, and how to administer an ABN if the exam is likely to be denied. Staff should also understand the restrictions on use of

With rapid evolution of multidetector-row CT (MDCT) technology and applications, several factors such ad technology upgrade and turf battles for sharing cost and profitability affect MDCT workflow and economics. MDCT workflow optimization can enhance productivity and reduce unit costs as well as increase profitability, in spite of decrease in reimbursement rates. Strategies for workflow management include standardization, automation, and constant assessment of various steps involved in MDCT operations. In this review article, we describe issues related to MDCT economics and workflow. (orig.)

Nearshore areas off of west-central Maui, Hawai‘i, once dominated by abundant coral coverage, now are characterized by an increased abundance of turf algae and macroalgae. In an effort to improve the health and resilience of the coral reef system, the Kahekili Herbivore Fisheries Management Area was established by the State of Hawai‘i, and the U.S. Coral Reef Task Force selected the Kā‘anapali region as a priority study area. To support these efforts, the U.S. Geological survey mapped nearly 5 km2 of sea floor from the shoreline to water depths of about 30 m. Unconsolidated sediment (predominantly sand) constitutes 65 percent of the sea floor in the mapped area. Reef and other hardbottom potentially available for coral recruitments constitutes 35 percent of the mapped area. Of this potentially available hardbottom, only 51 percent is covered with a minimum of 10 percent coral, and most is found between 5 and 10 m water depth.

from the company that treats and sells wastewater, if available or from another wastewater treatment company at a higher cost (but at a cost cheaper than that of desalination water) mainly due to the high demand season and the additional cost of trucking. In some cases, however, like in Sharm, the amount of treated wastewater is limited and variable during the year and some hotels have no choice but to partially use desalination water for irrigation. A conscious strategy for water management should rely solely on treated wastewater on-site. This can be achieved by: increasing the efficiency of the irrigation system, reducing the area of high-water consuming plantation (e.g. turf grass) and/or shifting to drought resistant plants including less water-consuming or salt tolerant turf grass.

The work environment and its effect on engagement and retention of nuclear medicine technologists: differences between public and private sector workers.

The retention of Australian nuclear medicine technologists (NMTs) is poor with the future workforce size in question. As a consequence, the primary aim of this study was to determine Australian NMTs' level of work engagement and the factors influencing this to identify the issues surrounding retention. The job demands resource model assumes that each job has its own demands and resources and the balance between these can influence the level of work engagement. Lower levels of work engagement are predictive of an intention to leave. Work engagement levels can be measured using the Utrecht work engagement scale. This study used the Utrecht Work Engagement Scale in a self-report questionnaire with additional open-ended and closed-ended items designed to evaluate satisfying job characteristics. Members of the professional body in specific geographical locations of Australia were invited to participate. A 49.6% response rate was achieved (n=201); of these, 164 were practicing NMTs. Public sector workers had significantly lower total mean scores (P=0.05) on the Utrecht Work Engagement Scale and the subscale of dedication (P=0.005) compared with private NMTs. Seven of the 14 job satisfaction closed-ended items were statistically significantly lower for public NMTs: the level of decision making; feelings of importance with the tasks performed; feedback on tasks and roles; and relationships with physicians, staff and the organization. To improve the retention of NMTs, changes in the job resources and demands are needed. Advanced practice roles may improve retention by enhancing the job resources.

2012-01-01

An instrumented Hybrid III head was placed in a Schutt ION 4D football helmet and dropped on different turfs to study field types and temperature on head responses. The head was dropped 0.91 and 1.83 m giving impacts of 4.2 and 6.0 m/s on nine different football fields (natural, Astroplay, Fieldturf, or Gameday turfs) at turf temperatures of -2.7 to 23.9 °C. Six repeat tests were conducted for each surface at 0.3 m (1') intervals. The Hybrid III was instrumented with triaxial accelerometers to determine head responses for the different playing surfaces. For the 0.91-m drops, peak head acceleration varied from 63.3 to 117.1 g and HIC(15) from 195 to 478 with the different playing surfaces. The lowest response was with Astroplay, followed by the engineered natural turf. Gameday and Fieldturf involved higher responses. The differences between surfaces decreased in the 1.83 m tests. The cold weather testing involved higher accelerations, HIC(15) and delta V for each surface. The helmet drop test used in this study provides a simple and convenient means of evaluating the compliance and energy absorption of football playing surfaces. The type and temperature of the playing surface influence head responses.

Evidence for water-mediated mechanisms in coral–algal interactions

2016-01-01

Although many coral reefs have shifted from coral-to-algal dominance, the consequence of such a transition for coral–algal interactions and their underlying mechanisms remain poorly understood. At the microscale, it is unclear how diffusive boundary layers (DBLs) and surface oxygen concentrations at the coral–algal interface vary with algal competitors and competitiveness. Using field observations and microsensor measurements in a flow chamber, we show that coral (massive Porites) interfaces with thick turf algae, macroalgae, and cyanobacteria, which are successful competitors against coral in the field, are characterized by a thick DBL and hypoxia at night. In contrast, coral interfaces with crustose coralline algae, conspecifics, and thin turf algae, which are poorer competitors, have a thin DBL and low hypoxia at night. Furthermore, DBL thickness and hypoxia at the interface with turf decreased with increasing flow speed, but not when thick turf was upstream. Our results support the importance of water-mediated transport mechanisms in coral–algal interactions. Shifts towards algal dominance, particularly dense assemblages, may lead to thicker DBLs, higher hypoxia, and higher concentrations of harmful metabolites and pathogens along coral borders, which in turn may facilitate algal overgrowth of live corals. These effects may be mediated by flow speed and orientation. PMID:27512146

2016-01-01

Purpose: To determine if the flipped class format has an effect on examination results for a radiologic technologist (RT) program and discuss benefits from creating video resources. Methods: From 2001–2015, students had taken both a radiological physics and quality control (QC) class as a part of their didactic training. In 2005/2006, the creation of videos of didactic lectures and QC test demonstrations allowed for a flip where content was studied at home while exercises and reviews were done in-class. Final examinations were retrospectively reviewed from this timeframe. 12 multiple choice physics questions (MCP) and 5 short answer QC questions (SAQC) were common to pre and post flip exams. The RT program’s ARRT exam scores were also obtained and compared to national averages. Results: In total, 36 lecture videos and 65 quality control videos were created for the flipped content. Data was ∼2.4GB and distributed to students via USB or CD media. For MCP questions, scores improved by 7.9% with the flipped format and significance (Student’s t-test, p<0.05) was found for 3 of the 12 questions. SAQC questions showed improvement by 14.6% and significance was found for 2 of the 5 questions. Student enrollment increased from ∼14 (2001–2004) to ∼23 students (2005–15). Content was continuously added post-flip due to the efficiency of delivery. The QC class in 2003 covered 45 test setups in-class while 65 were covered with video segments in 2014. Flipped materials are currently being repurposed. In 2015, this video content was restructured into an ARRT exam review guide and in 2016, the content was reorganized for fluoroscopy training for physicians. Conclusion: We believe that flipped classes can improve efficiency of content delivery and improve student performance even with an increase in class size. This format allows for flexibility in learning as well as re-use in multiple applications.

Effectively Managing Nuclear Risk Through Human Performance Improvement

International Nuclear Information System (INIS)

Coe, Richard; Lake, Patricia

2003-01-01

The U.S. commercial nuclear industry has just completed an outstanding decade of plant performance. Safety levels and electric production are at unprecedented high levels and continue to exceed even high industry goals. Nuclear energy continues to keep the highest priority on performance improvement programs and highly trained and qualified people that maintain its record setting safety and reliability of operations. While the industry has maintained a high level of performance, the advent of deregulation and the consolidation of nuclear power plant ownership, as well as the current climate for concern about both rising energy costs and the availability of power, have raised the standard for nuclear energy's level of competitiveness in today's market place. The resulting challenge is how to more effectively manage risk and to improve performance even further in a generally high-performing industry. One of the most effective ways to develop this culture is to apply the principles of Hum an Performance Technology, or HPT. HPT is a relatively new field. Its principles are derived from the research and practice of behavioral and cognitive psychologists, instructional technologists, training designers, organizational developers, and various human resource specialists. Using the principles of HPT can help the nuclear industry successfully meet ever-changing environmental and business demands

Kosaka, Tadako

1979-01-01

A questionaire survey of the quality control and the radiation control was performed on the laboratories of 34 university hospitals, 29 community hospitals, 4 research institutes and 9 commercial radioassay laboratories as well. 1) Management of the usage of radioisotopes. In 79% of the laboratories, the usage of radioisotope including the purchasing and discarding, was under the control of centralized organization, such as the central radioisotope division. The radioassays were performed by full time physicians in 18.9% and by technologists in 72.4% of the surveyed laboratories. 2) Management of instruments. 90.8% of the laboratories has a regular program for background counting, examination for contamination and energy spectrum adjustment. The measurement of radioactivity and calculation of the data were carried out on an automated system in a majority of the laboratories: the percentage of the use of these automated systems were 92.1% for measurement, and 76.3% for calculation respectively. The automated system, however, which covers entire procedure: pipeting of samples and reagents, and B/F separation was used in only 7.9 - 18.4%. 3) Quality control. 89.5% of the laboratory had a specific quality control program for radioassay. Main causes of errors they had encountered were: problems in commercial kits, handling of samples, instrument performance, technical and clerical errors in that order. To prevent these errors, it was thought important to establish the detailed protocols for the radioassay performance. (author)

Off-site transport of fungicides with runoff: A comparison of flutolanil and pentachloronitrobeneze applied to creeping bentgrass managed as a golf course fairway.

Science.gov (United States)

Rice, Pamela J; Horgan, Brian P; Hamlin, Jennifer L

2018-08-15

Flutolanil and pentachloronitrobenzene (PCNB) are fungicides used to control or suppress foliar and soil borne diseases in turf and ornamental crops. On golf courses, sports fields, sod farms and commercial lawns these fungicides are used as preventive treatments to combat snow mold, brown patch and fairy ring. Depending on the aquatic organism, flultolanil and PCNB are considered to be moderately to highly toxic. Therefore runoff or drift from treated areas may be hazardous to organisms in adjacent aquatic sites. This research compared the transport of flutolanil and PCNB with runoff from turfgrass managed as a golf course fairway. The quantity of fungicide transported with runoff and observations reported with the chemographs followed trends in agreement with the chemical properties of the compounds. Overall, we observed the rate of transport for flutolanil was greater than PCNB, which contributed to the more than 12 times larger load (µg/m 2 ) of flutolanil transported off-site at the conclusion of the simulated storm runoff. A better understanding of the off-site transport of pesticides with runoff is needed to make informed decisions on management practices to reduce potential adverse effects on non-target organisms, as well as maintain control of targeted pests in the area of application. In addition, data obtained with this research can be used in model simulations to predict nonpoint source pollution potentials beyond experimental conditions. Copyright © 2018.

Add-on conservation benefits of marine territorial user rights fishery policies in central Chile.

Science.gov (United States)

Gelcich, Stefan; Godoy, Natalio; Prado, Luis; Castilla, Juan Carlos

2008-01-01

To combine the rational use of marine benthic resources and economic development of small-scale fishers, Chile passed legislation in 1991 establishing a comanagement policy that grants exclusive territorial user rights for fisheries (TURFs) to artisanal fisher organizations in well-defined inshore coastal areas, known as Management and Exploitation Areas for Benthic Resources (MEABRs). In general the policy has been proclaimed a management and economic success because benthic resource abundances have increased inside MEABRs in comparison with open-access areas. However, there is a lack of studies assessing the impact of this management policy on nontargeted subtidal species and community assemblages and the policy's implications for biodiversity and conservation. This study starts to fill this gap and links the allocation of TURFs for benthic resources with add-on conservation benefits for species that are not directly linked with the fishery policy. Comparative subtidal surveys inside vs. outside MEABRs were used to assess the effects of three MEABRs on managed targeted benthic species, biodiversity (species richness), and community assemblages in central Chile. Surveys focused exclusively on subtidal kelp forest habitats dominated by Lessonia trabeculata, spanning 4-12 m in depth and with similar levels of habitat complexity. The study comprised: (1) quantification of kelp forest complexity, (2) understory survey of sessile species, (3) quantification of conspicuous benthic macroinvertebrates, including those under management, and (4) quantification of reef-fish species inside the kelp habitat. Results showed population enhancement of target-managed invertebrates inside MEABRs. Moreover, reef-fish species were significantly more diverse and abundant inside MEABRs, and community assemblages of nontarget benthic invertebrates and reef fish were significantly different inside vs. outside MEABRs.

Schott, K.; Balster, N. J.; Johnston, M. R.

2009-12-01

Although case studies report improved control of urban stormwater within residential rain gardens, the extent to which vegetation type (shrub, turf, prairie) affects the saturated hydraulic conductivity (Ksat) of these depressions has yet to be investigated in a controlled experiment. We hypothesized that there would be significant differences in hydraulic conductivity by vegetation type due to differences in soil physical characteristics and rooting dynamics such that Ksat of shrub gardens would exceed that of prairie, followed by turf. To test this hypothesis, we measured changes in Ksat relative to the above vegetation types as well as non-vegetative controls, each of which were replicated three times for a total of 12 rain gardens. Ksat was calculated using a published method for curve-fitting to single-ring infiltration with a two-head approach where the shape factor is independent of ponding depth. Constant-head infiltration rates were measured at two alternating ponding depths within each garden twice over the growing season. Root core samples were also taken to qualify belowground characteristics including soil bulk density and rooting dynamics relative to differences in Ksat. We found the control and shrub gardens had the lowest mean Ksat of 3.56 (SE = 0.96) and 3.73 (1.22) cm3 hr-1, respectively. Prairie gardens had the next highest mean Ksat of 12.18 (2.26) cm3 hr-1, and turf had the highest mean value of 23.63 (1.81) cm3 hr-1. These data suggest that a denser rooting network near the soil surface may influence saturated hydraulic conductivity. We applied our observed flow rates to a Glover solution model for 3-dimensional flow, which revealed considerably larger discrepancies in turf gardens than beneath prairie or shrub. This indicated that lateral flow conditions in the turf plots could be the explanation for our observed infiltration rates.

Competition between reef-building corals and benthic algae is of key importance for reef dynamics. These interactions occur on many spatial scales, ranging from chemical to regional. Using microprobes, 16S rDNA pyrosequencing and underwater surveys, we examined the interactions between the reef-building coral Montastraea annularis and four types of benthic algae. The macroalgae Dictyota bartayresiana and Halimeda opuntia, as well as a mixed consortium of turf algae, caused hypoxia on the adjacent coral tissue. Turf algae were also associated with major shifts in the bacterial communities at the interaction zones, including more pathogens and virulence genes. In contrast to turf algae, interactions with crustose coralline algae (CCA) and M. annularis did not appear to be antagonistic at any scale. These zones were not hypoxic, the microbes were not pathogen-like and the abundance of coral-CCA interactions was positively correlated with per cent coral cover. We propose a model in which fleshy algae (i.e. some species of turf and fleshy macroalgae) alter benthic competition dynamics by stimulating bacterial respiration and promoting invasion of virulent bacteria on corals. This gives fleshy algae a competitive advantage over corals when human activities, such as overfishing and eutrophication, remove controls on algal abundance. Together, these results demonstrate the intricate connections and mechanisms that structure coral reefs.

Failure occurs because traditional efforts to improve IT performance treat project delivery as an operational endeavor driven by technologists. Progress, these technologists say, lies in ever more complex implementation methodologies. In reality, an IT project is a business endeavor which must be evaluated in financial terms, both as a standalone effort and in relation to other efforts competing for resources. Moreover, a client or vendor’s projects represent a rolling collection of endeavors. They are best analyzed and managed as a portfolio. Proof of success will not only come through better project delivery and business ROI but the ability to insure IT projects for timeliness, adherence to budget, and full functionality

2009-12-01

Content Management Systems (CMSs) provide powerful features that can be of use to oceanographic (and other geo-science) data managers. However, in many instances, geo-science data management offices have previously designed customized schemas for their metadata. The WHOI Ocean Informatics initiative and the NSF funded Biological Chemical and Biological Data Management Office (BCO-DMO) have jointly sponsored a project to port an existing, relational database containing oceanographic metadata, along with an existing interface coded in Cold Fusion middleware, to a Drupal6 Content Management System. The goal was to translate all the existing database tables, input forms, website reports, and other features present in the existing system to employ Drupal CMS features. The replacement features include Drupal content types, CCK node-reference fields, themes, RDB, SPARQL, workflow, and a number of other supporting modules. Strategic use of some Drupal6 CMS features enables three separate but complementary interfaces that provide access to oceanographic research metadata via the MySQL database: 1) a Drupal6-powered front-end; 2) a standard SQL port (used to provide a Mapserver interface to the metadata and data; and 3) a SPARQL port (feeding a new faceted search capability being developed). Future plans include the creation of science ontologies, by scientist/technologist teams, that will drive semantically-enabled faceted search capabilities planned for the site. Incorporation of semantic technologies included in the future Drupal 7 core release is also anticipated. Using a public domain CMS as opposed to proprietary middleware, and taking advantage of the many features of Drupal 6 that are designed to support semantically-enabled interfaces will help prepare the BCO-DMO database for interoperability with other ecosystem databases.

Proposal for the establishment of an International Centre for Resource Management (ICRM)

International Nuclear Information System (INIS)

Islam, S.

1999-01-01

Energy and physical resources are necessary for development. These resources are not scarce. What is scarce is Technology. Technology is not only machines, it is also knowledge to run these machines. Most of the developing countries waste whatever resources they do have because of a lack of scientists, technologists and modern management. The main reason for underdevelopment of the poor countries is their weak linkage to modern science and technology. The scientists in the developing countries are isolated. Science cannot survive, let alone flourish, in isolation. The International Centre for Theoretical Physics in Trieste, Italy (ICTP) was established to end scientific isolation and to stop brain drain. The centre was established in 1964 under the auspices of the International Atomic Energy Agency (IAEA). Now the centre's Management is run by the United Nations Educational, Scientific and Cultural Organization (UNESCO), ICTP in Trieste started in 1964 with a budget of US$ 355,000. The building was donated by the Government of Italy. Now its budget is about US$ 20 million (90 per cent from Italy). About 4,000 scientists visit the centre every year. Since its establishment about 40,000 scientists from developing countries and 20,000 from developed countries have visited ICTP. The principal purpose of the proposed International Centre for Resource Management will be to foster through seminars, conferences, teaching and research the advancement of better resource utilization and environmental protection in the less developed countries.

The US Department of Energy (DOE) is required to characterize approximately 3,700 contaminated sites, 1.5 million barrels of stored waste, 385,000 m 3 of high-level radioactive waste in tanks, and between 1,700 and 7,000 facilities before site remediation, waste treatment, and facility deactivation and decontamination (D and D) operations commence. Specifically, characterization technologies are being developed to address five major problem areas: mixed waste treatment, facility D and D, mapping and treatment of contaminant plumes in soil and groundwater, landfill stabilization, retrieval and remediation, and retrieval and treatment of high-level radioactive waste from underground storage tanks. DOE's Office of Technology Development (OTD) within the Office of Environmental Management is entirely focused on projects to address these five areas

Veterinary technology has generally established itself well in companion-animal and mixed-animal veterinary medical practice, but the career's growth trajectory is uncertain. Michigan State University (MSU) convened a national conference, "Creating the Future of Veterinary Technology-A National Dialogue," in November 2011 to explore ways to elevate the veterinary technician/technologist's role in the veterinary medical profession and to identify new directions in which the career could expand. Veterinary technicians/technologists might advance their place in private practice by not only improving their clinical skills, but by also focusing on areas such as practice management, leadership training, business training, conflict resolution, information technology, and marketing/communications. Some new employment settings for veterinary technicians/technologists include more participation within laboratory animal medicine and research, the rural farm industry, regulatory medicine, and shelter medicine. Achieving these ends would call for new training options beyond the current 2-year and 4-year degree programs. Participants suggested specialty training programs, hybrid programs of various types, online programs, veterinary technician residency programs of 12-18 months, and more integration of veterinary technician/technology students and veterinary medicine students at colleges of veterinary medicine.

Full Text Available Local-scale ecological information is critical as a sound basis for spatial management and conservation and as support for ongoing research in relatively unstudied areas. We conducted visual surveys of fish and benthic communities on nine reefs (3–24 km from shore in the Thuwal area of the central Saudi Arabian Red Sea. Fish biomass increased with increasing distance from shore, but was generally low compared to reefs experiencing minimal human influence around the world. All reefs had a herbivore-dominated trophic structure and few top predators, such as sharks, jacks, or large groupers. Coral cover was considerably lower on inshore reefs, likely due to a 2010 bleaching event. Community analyses showed inshore reefs to be characterized by turf algae, slower-growing corals, lower herbivore diversity, and highly abundant turf-farming damselfishes. Offshore reefs had more planktivorous fishes, a more diverse herbivore assemblage, and faster-growing corals. All reefs appear to be impacted by overfishing, and inshore reefs seem more vulnerable to thermal bleaching. The study provides a description of the spatial variation in biomass and community structure in the central Saudi Arabian Red Sea and provides a basis for spatial prioritization and subsequent marine protected area design in Thuwal.

Full Text Available This study evaluated the effectiveness of two bioswales eight years after construction in Davis, California. The treatment bioswale measured 9 m × 1 m × 1 m (L × W × D. Engineered soil mix (75% native lava rock and 25% loam soil replaced the native loam soil. Four Red Tip Photinia (Photinia × fraseri Dress trees and two Blueberry Muffin Hawthorn (Rhaphiolepis umbellata (Thunb. Makino shrubs were planted in the bioswale. Runoff flowed into the bioswale from an adjacent 171 m2 panel of turf grass. An identically sized control bioswale consisting of non-disturbed native soil was located adjacent to the treatment bioswale. Surface runoff quantity and quality were measured during three experiments with different pollutant loads. When compared to the control, the treatment bioswale reduced surface runoff by 99.4%, and reduced nitrogen, phosphate, and total organic carbon loading by 99.1%, 99.5%, and 99.4%, respectively. After eight years, tree growth characteristics were similar across both sites.

Interdisciplinary conflict and organizational complexity.

Guy, M E

Most people think that conflict among the professional staff is inevitable and results from each profession's unique set of values. Each profession then defends itself by claiming its own turf. This article demonstrates that organizational complexity, not professional territorialism, influences the amount of intraorganizational conflict. In a comparison of two psychiatric hospitals, this study shows that there is not necessarily greater conflict across professions than within professions. However, there is a significantly greater amount of conflict among staff at a structurally more complex hospital than at a less-complex hospital, regardless of profession. Implications for management are discussed.

Quality management audits in nuclear medicine practices

International Nuclear Information System (INIS)

2008-12-01

An effective management system that integrates quality management (QM) is essential in modern nuclear medicine departments in Member States. The IAEA, in its Safety Standards Series, has published a Safety Requirement (GS-R-3) and a Safety Guide (GS-G-3.1) on management systems for all facilities. These publications address the application of an integrated management system approach that is applicable to nuclear medicine organizations as well. Quality management systems are maintained with the intent to continuously improve effectiveness and efficiency, enabling nuclear medicine to achieve the expectations of its quality policy, and to satisfy its customers. The IAEA has a long history of providing assistance in the field of nuclear medicine to its Member States. Regular quality audits and assessments are essential for modern nuclear medicine departments. More importantly, the entire QM and audit process has to be systematic, patient oriented and outcome based. The management of services should also take into account the diversity of nuclear medicine services around the world and multidisciplinary contributions. The latter include clinical, technical, radiopharmaceutical and medical physics procedures. Aspects of radiation safety and patient protection should also be integral to the process. Such an approach ensures consistency in providing safe, quality and superior services to patients. Increasingly standardized clinical protocol and evidence based medicine is used in nuclear medicine services, and some of these are recommended in numerous IAEA publications, for example, the Nuclear Medicine Resources Manual. Reference should also be made to other IAEA publications such as the IAEA Safety Standards Series, which include the regulations for the safe transport of nuclear material and on waste management as all of these have an impact on the provision of nuclear medicine services. The main objective of this publication is to introduce a routine of conducting an

The quality of patient care is critically influenced by the availability of accurate information and its efficient management. Radiation oncology consists of many information components, for example there may be information related to the patient (e.g., profile, disease site, stage, etc.), to people (radiation oncologists, radiological physicists, technologists, etc.), and to equipment (diagnostic, planning, treatment, etc.). These different data must be integrated. A comprehensive information management system is essential for efficient storage and retrieval of the enormous amounts of information. A radiation therapy patient information system (RTPIS) has been developed using open source software. PHP and JAVA script was used as the programming languages, MySQL as the database, and HTML and CSF as the design tool. This system utilizes typical web browsing technology using a WAMP5 server. Any user having a unique user ID and password can access this RTPIS. The user ID and password is issued separately to each individual according to the person's job responsibilities and accountability, so that users will be able to only access data that is related to their job responsibilities. With this system authentic users will be able to use a simple web browsing procedure to gain instant access. All types of users in the radiation oncology department should find it user-friendly. The maintenance of the system will not require large human resources or space. The file storage and retrieval process would be be satisfactory, unique, uniform, and easily accessible with adequate data protection. There will be very little possibility of unauthorized handling with this system. There will also be minimal risk of loss or accidental destruction of information.

Carbon Sequestration and Nitrous Oxide Emissions from Urban Turfgrass Ecosystems in Southern California

Science.gov (United States)

Ampleman, M. D.; Czimczik, C. I.; Townsend-Small, A.; Trumbore, S. E.

2008-12-01

Irrigated turfgrass ecosystems sequester carbon in soil organic matter, but they may also release nitrous oxide, due to fertilization associated with intensive management practices. Nitrous oxide is an important green house gas with a global warming potential (GWP) of 300 times that of carbon dioxide on a 100 yr time horizon. Although regular irrigation and fertilization of turfgrass create favorable conditions for both C storage and N2O release via nitrification and denitrification by soil microbes, emissions from these highly managed ecosystems are poorly constrained. We quantified N2O emissions and C storage rates for turf grass in four urban parks in the city of Irvine, CA. The turf grass systems we studied were managed by the City of Irvine. Parks were established between 1975 and 2006 on former range land with the same initial parent material; are exposed to the same climate; and form a time series (chronosequence) for investigating rates of C accumulation. We also investigated the effects of management (e.g. grass species, fertilization rate), soil moisture and temperature, and park age on N2O emission from these parks. We quantified N2O emissions using static soil chamber with four 7 min. sampling intervals, and analyzed the samples using an electron capture gas chromatograph. Soil carbon accumulation rates were determined from the slope of the organic C inventory (from 0-20 cm depth) plotted against park age. C storage rates for soils in "leisure" areas were close to 2 Mg C ha-1 yr-1, similar to rates associated with forest regrowth in northeastern US forests. However, as park age and C storage increased, N2O emissions increased as well, such that emissions from the older parks (~20 ngN m-2 s-1) were comparable to published temperate agricultural fluxes. Initial estimates suggest that the GWP associated with N2O emissions approximately offsets the effect of C storage in these ecosystems.

2017-08-21

Health leadership and management capacity are essential for health system strengthening and for attaining universal health coverage by optimising the existing human, technological and financial resources. However, in health systems, health leadership and management training is not widely available. The use of information technology for education (ie, eLearning) could help address this training gap by enabling flexible, efficient and scalable health leadership and management training. We present a protocol for a systematic review on the effectiveness of eLearning for health leadership and management capacity building in improving health system outcomes. We will follow the Cochrane Collaboration methodology. We will search for experimental studies focused on the use of any type of eLearning modality for health management and leadership capacity building in all types of health workforce cadres. The primary outcomes of interest will be health outcomes, financial risk protection and user satisfaction. In addition, secondary outcomes of interest include the attainment of health system objectives of improved equity, efficiency, effectiveness and responsiveness. We will search relevant databases of published and grey literature as well as clinical trials registries from 1990 onwards without language restrictions. Two review authors will screen references, extract data and perform risk of bias assessment independently. Contingent on the heterogeneity of the collated literature, we will perform either a meta-analysis or a narrative synthesis of the collated data. The systematic review will aim to inform policy makers, investors, health professionals, technologists and educators about the existing evidence, potential gaps in literature and the impact of eLearning for health leadership and management capacity building on health system outcomes. We will disseminate the review findings by publishing it as a peer-reviewed journal manuscript and conference abstracts. PROSPERO CRD

Evaluating Vegetation Type Effects on Land Surface Temperature at the City Scale

Wetherley, E. B.; McFadden, J. P.; Roberts, D. A.

2017-12-01

Understanding the effects of different plant functional types and urban materials on surface temperatures has significant consequences for climate modeling, water management, and human health in cities. To date, doing so at the urban scale has been complicated by small-scale surface heterogeneity and limited data. In this study we examined gradients of land surface temperature (LST) across sub-pixel mixtures of different vegetation types and urban materials across the entire Los Angeles, CA, metropolitan area (4,283 km2). We used AVIRIS airborne hyperspectral imagery (36 m resolution, 224 bands, 0.35 - 2.5 μm) to estimate sub-pixel fractions of impervious, pervious, tree, and turfgrass surfaces, validating them with simulated mixtures constructed from image spectra. We then used simultaneously imaged LST retrievals collected at multiple times of day to examine how temperature changed along gradients of the sub-pixel mixtures. Diurnal in situ LST measurements were used to confirm image values. Sub-pixel fractions were well correlated with simulated validation data for turfgrass (r2 = 0.71), tree (r2 = 0.77), impervious (r2 = 0.77), and pervious (r2 = 0.83) surfaces. The LST of pure pixels showed the effects of both the diurnal cycle and the surface type, with vegetated classes having a smaller diurnal temperature range of 11.6°C whereas non-vegetated classes had a diurnal range of 16.2°C (similar to in situ measurements collected simultaneously with the imagery). Observed LST across fractional gradients of turf/impervious and tree/impervious sub-pixel mixtures decreased linearly with increasing vegetation fraction. The slopes of decreasing LST were significantly different between tree and turf mixtures, with steeper slopes observed for turf (p < 0.05). These results suggest that different physiological characteristics and different access to irrigation water of urban trees and turfgrass results in significantly different LST effects, which can be detected at

Full Text Available Despite the wide use of newer techniques in genetic diagnostics, there remains a need for technologists to learn human chromosome morphology, identify abnormal metaphases and report clinical abnormalities. Global short age of cytogenetic trainers and a time consuming training process makes Karyotyping training difficult. We have developed a web based interactive Karyotyping training tool, KaryoTutor©, that allows technologists to learn karyotyping in an interactive environment and aids the trainer in the training process. KaryoTutor©provides visual clues for identifying abnormal chromosomes, provides instant test scores and includes a reference library of ideograms,sample chromosome images and reference materials. Trainees are able to recursively work on a case till a satisfactory result is achieved,with KaryoTutor providing interactive inputs.Additionally, trainers can assign cases and monitor trainee progress using audit trail management and other administrative features.

Countries worldwide are challenged by health worker shortages, skill mix imbalances, and maldistribution. Human resources information systems (HRIS) are used to monitor and address these health workforce issues, but global understanding of such systems is minimal and baseline information regarding their scope and capability is practically non-existent. The Kenya Health Workforce Information System (KHWIS) has been identified as a promising example of a functioning HRIS. The objective of this paper is to document the impact of KHWIS data on human resources policy, planning and management. Sources for this study included semi-structured interviews with senior officials at Kenya's Ministry of Medical Services (MOMS), Ministry of Public Health and Sanitation (MOPHS), the Department of Nursing within MOMS, the Nursing Council of Kenya, Kenya Medical Practitioners and Dentists Board, Kenya's Clinical Officers Council, and Kenya Medical Laboratory Technicians and Technologists Board. Additionally, quantitative data were extracted from KHWIS databases to supplement the interviews. Health sector policy documents were retrieved from MOMS and MOPHS websites, and reviewed to assess whether they documented any changes to policy and practice as having been impacted by KHWIS data. Interviews with Kenyan government and regulatory officials cited health workforce data provided by KHWIS influenced policy, regulation, and management. Policy changes include extension of Kenya's age of mandatory civil service retirement from 55 to 60 years. Data retrieved from KHWIS document increased relicensing of professional nurses, midwives, medical practitioners and dentists, and interviewees reported this improved compliance raised professional regulatory body revenues. The review of Government records revealed few references to KHWIS; however, documentation specifically cited the KHWIS as having improved the availability of human resources for health information regarding workforce planning

Expanding the scope of practice for radiology managers: radiation safety duties.

Science.gov (United States)

Orders, Amy B; Wright, Donna

2003-01-01

In addition to financial responsibilities and patient care duties, many medical facilities also expect radiology department managers to wear "safety" hats and complete fundamental quality control/quality assurance, conduct routine safety surveillance in the department, and to meet regulatory demands in the workplace. All managers influence continuous quality improvement initiatives, from effective utilization of resource and staffing allocations, to efficacy of patient scheduling tactics. It is critically important to understand continuous quality improvement (CQI) and its relationship with the radiology manager, specifically quality assurance/quality control in routine work, as these are the fundamentals of institutional safety, including radiation safety. When an institution applies for a registration for radiation-producing devices or a license for the use of radioactive materials, the permit granting body has specific requirements, policies and procedures that must be satisfied in order to be granted a permit and to maintain it continuously. In the 32 U.S. Agreement states, which are states that have radiation safety programs equivalent to the Nuclear Regulatory Commission programs, individual facilities apply for permits through the local governing body of radiation protection. Other states are directly licensed by the Nuclear Regulatory Commission and associated regulatory entities. These regulatory agencies grant permits, set conditions for use in accordance with state and federal laws, monitor and enforce radiation safety activities, and audit facilities for compliance with their regulations. Every radiology department and associated areas of radiation use are subject to inspection and enforcement policies in order to ensure safety of equipment and personnel. In today's business practice, department managers or chief technologists may actively participate in the duties associated with institutional radiation safety, especially in smaller institutions, while

Impact on Clinical Management of After-Hours Emergent or Urgent Breast Ultrasonography in Patients with Clinically Suspected Breast Abscesses

Full Text Available Newly diagnosed breast abscesses are generally treated as a medical emergency that may necessitate immediate interventional treatment. At our institution, there is no in-house after-hours coverage for breast ultrasonography. We could find no peer-reviewed studies on the cost-effectiveness or clinical management impact of on-call ultrasound technologist coverage for imaging of breast abscesses. The purposes of this study were to determine the incidence of breast abscess in patients with clinical findings highly suggestive of abscess, identify clinical factors associated with breast abscess in such patients, and determine the impact of after-hours emergent or urgent breast ultrasonography on the clinical management of breast abscesses in both outpatients and inpatients. We retrospectively reviewed 100 after-hours breast ultrasound studies performed at our tertiary care center from 2011 to 2015 for evaluation of a suspected breast abscess. Only 26% of our patients with clinically suspected abscess ultimately had a confirmed abscess. Factors associated with breast abscess were a palpable abnormality and a history of breast surgery within the eight weeks before presentation. After-hours diagnosis of an abscess was associated with after-hours clinical intervention. Of the 74 patients in whom after-hours ultrasound imaging showed no evidence of abscess, only three patients underwent after-hours drainage. Our findings support overnight and weekend breast ultrasound coverage in large tertiary care centers.

We retrospectively reviewed 100 after-hours breast ultrasound studies performed at our tertiary care center from 2011 to 2015 for evaluation of a suspected breast abscess. Only 26% of our patients with clinically suspected abscess ultimately had a confirmed abscess. Factors associated with breast abscess were a palpable abnormality and a history of breast surgery within the eight weeks before presentation. After-hours diagnosis of an abscess was associated with after-hours clinical intervention. Of the 74 patients in whom after-hours ultrasound imaging showed no evidence of abscess, only three patients underwent after-hours drainage. Our findings support overnight and weekend breast ultrasound coverage in large tertiary care centers. PMID:29473859

Newly diagnosed breast abscesses are generally treated as a medical emergency that may necessitate immediate interventional treatment. At our institution, there is no in-house after-hours coverage for breast ultrasonography. We could find no peer-reviewed studies on the cost-effectiveness or clinical management impact of on-call ultrasound technologist coverage for imaging of breast abscesses.

Current clinical guidelines for the management of radiotherapy patients having either a pacemaker or implantable cardioverter defibrillator (both CIEDs: Cardiac Implantable Electronic Devices) do not cover modern radiotherapy techniques and do not take the patient’s perspective into account. Available data on the frequency and cause of CIED failure during radiation therapy are limited and do not converge. The Dutch Society of Radiotherapy and Oncology (NVRO) initiated a multidisciplinary task group consisting of clinical physicists, cardiologists, radiation oncologists, pacemaker and ICD technologists to develop evidence based consensus guidelines for the management of CIED patients. CIED patients receiving radiotherapy should be categorised based on the chance of device failure and the clinical consequences in case of failure. Although there is no clear cut-off point nor a clear linear relationship, in general, chances of device failure increase with increasing doses. Clinical consequences of device failures like loss of pacing, carry the most risks in pacing dependent patients. Cumulative dose and pacing dependency have been combined to categorise patients into low, medium and high risk groups. Patients receiving a dose of less than 2 Gy to their CIED are categorised as low risk, unless pacing dependent since then they are medium risk. Between 2 and 10 Gy, all patients are categorised as medium risk, while above 10 Gy every patient is categorised as high risk. Measures to secure patient safety are described for each category. This guideline for the management of CIED patients receiving radiotherapy takes into account modern radiotherapy techniques, CIED technology, the patients’ perspective and the practical aspects necessary for the safe management of these patients. The guideline is implemented in The Netherlands in 2012 and is expected to find clinical acceptance outside The Netherlands as well

Full Text Available To fertilize both grassland and turf lawns waste materials, including the substrate after mushroom cultivation have been used recently. The aim of this study was to determine the effect of the mushrooms substrate to change the amount of root mass of five turf lawns with varying precipitation of perennial ryegrass. Field experiment was established in 2004 in the agricultural station of University of Natural Science and Humanities in Siedlce. In the research, the following factors were used: 1 dose of mushroom substrate, 2 the mixtures lawns with different species composition and participation of perennial ryegrass. Within two years of research the evaluation of the amount of root mass of turf lawns were done. This assessment was made after plants’ vegetation in 2005 and 2006. The roots sampling of lawns were taken. After cleaning of the root and drying at 1050C, the mass was determined by weighing. The largest mass of roots (average from the study years and substrate doses was observed for the two-component mixture (M1 with 80% share of perennial ryegrass, and the smallest for five-component mixture (M5, where the share of perennial ryegrass was 40%. The average for research years of and mixtures type, indicates that most of the root mass formed the turf lawns with the largest mushroom substrate doses, but at least on the control object. The majority of the tested lawn mixtures, with the exception of mixture five (M5 produced a greater mass of roots in the second year (2006 than in the first (2005 year, despite worse weather conditions.

Ground level air convection produces frost damage patterns in turfgrass.

Ackerson, Bruce J; Beier, Richard A; Martin, Dennis L

2015-11-01

Frost injury patterns are commonly observed on the warm-season turfgrass species bermudagrass (Cynodon species Rich.), zoysiagrass (Zoysia species Willd.), and buffalograss [Bouteloua dactyloides (Nutt.) J.T. Columbus] in cool-temperate and subtropical zones. Qualitative observations of these injury patterns are presented and discussed. A model for the formation of such patterns based on thermal instability and convection of air is presented. The characteristic length scale of the observed frost pattern injury requires a temperature profile that decreases with height from the soil to the turfgrass canopy surface followed by an increase in temperature with height above the turfgrass canopy. This is justified by extending the earth temperature theory to include a turf layer with atmosphere above it. Then the theory for a thermally unstable layer beneath a stable region by Ogura and Kondo is adapted to a turf layer to include different parameter values for pure air, as well as for turf, which is treated as a porous medium. The earlier porous medium model of Thompson and Daniels proposed to explain frost injury patterns is modified to give reasonable agreement with observed patterns.

This study aimed to analyze the influence of the playing surface on movement pattern, physical loading, perceived exertion, and fatigue development during small-sided recreational soccer games. Time-motion, heart rate, blood lactate, and perceived exertion were measured for 16 recreational players aged 22 (range: 19-35) yrs. During 5-a-side soccer games on 3 different field surfaces: sand, artificial turf, and asphalt. Jump and sprint tests were performed prior to and after each game. Total distance covered was higher on asphalt and turf than on sand (3.89±0.04 and 3.73±0.12 vs. 2.59±0.21 km; p90% HR(max) (20.8±5.1% vs. 44.1±5.0%) were lower (precreational soccer games elicit high heart rates, multiple intense actions, and decreased jump performance for all the investigated playing surfaces, suggesting that multiple fitness and health benefits can be achieved through soccer on sand, artificial turf and asphalt. Nonetheless, locomotor activities, heart rate, blood lactate levels, and perceived exertion differ between surfaces. Copyright © 2012 Elsevier B.V. All rights reserved.

Renegotiating property rights in the Florida golden crab fishery

Full Text Available The golden crab (Chaceon fenneri supports a small, economically healthy fishery in south Florida. Crabbers in the fishery have successfully protected themselves against larger outside fishing interests in the past, and management has been stable for over fifteen years.  Why, then, did a portion of the fleet propose shifting to individual transferable quotas (ITQs?  Our findings suggest that proponents sought ITQ management because they believed it would further limit the ability of other crabbers to enter the fishery and act as a mechanism to legally preserve the informal and formal property rights that they have previously negotiated among themselves. Opponents believed that a shift to an ITQ regime would destroy those same property rights.  We explore the implications of these findings to a broader understanding of property rights and natural resource management institutions, noting that the currently existing system closely resembles a territorial use rights fishery (TURF.

There is a need for a selective, low-risk herbicide that can be used to control weeds in cereal cultures and turf. The present invention discloses that a bacterial secondary metabolite, thaxtomin and optionally another herbicide is an effective herbicide on broadleaved, sedge and grass weeds. Thaxtomin A and structurally similar compounds can be used as natural herbicides to control the germination and growth of weeds in cereal, turf grass, Timothy grass and pasture grass cultures with no phytotoxicity to these crops. As a natural, non-toxic compound, thaxtomin can be used as a safe alternative for weed control in both conventional and organic farming and gardening systems.

Compliance with AAPM Practice Guideline 1.a: CT Protocol Management and Review — from the perspective of a university hospital

Science.gov (United States)

Bour, Robert K.; Pozniak, Myron; Ranallo, Frank N.

2015-01-01

The purpose of this paper is to describe our experience with the AAPM Medical Physics Practice Guideline 1.a: “CT Protocol Management and Review Practice Guideline”. Specifically, we will share how our institution's quality management system addresses the suggestions within the AAPM practice report. We feel this paper is needed as it was beyond the scope of the AAPM practice guideline to provide specific details on fulfilling individual guidelines. Our hope is that other institutions will be able to emulate some of our practices and that this article would encourage other types of centers (e.g., community hospitals) to share their methodology for approaching CT protocol optimization and quality control. Our institution had a functioning CT protocol optimization process, albeit informal, since we began using CT. Recently, we made our protocol development and validation process compliant with a number of the ISO 9001:2008 clauses and this required us to formalize the roles of the members of our CT protocol optimization team. We rely heavily on PACS‐based IT solutions for acquiring radiologist feedback on the performance of our CT protocols and the performance of our CT scanners in terms of dose (scanner output) and the function of the automatic tube current modulation. Specific details on our quality management system covering both quality control and ongoing optimization have been provided. The roles of each CT protocol team member have been defined, and the critical role that IT solutions provides for the management of files and the monitoring of CT protocols has been reviewed. In addition, the invaluable role management provides by being a champion for the project has been explained; lack of a project champion will mitigate the efforts of a CT protocol optimization team. Meeting the guidelines set forth in the AAPM practice guideline was not inherently difficult, but did, in our case, require the cooperation of radiologists, technologists, physicists, IT

This study aimed to investigate the influence of display window setting on technologist performance detecting subtle but clinically relevant artifacts in daily computed tomography (CT) quality control (dQC) images. Fifty three sets of dQC images were retrospectively selected, including 30 sets without artifacts, and 23 with subtle but clinically relevant artifacts. They were randomized and shown to six CT technologists (two new and four experienced). Each technologist reviewed all images in each of two sessions, one with a display window width (WW) of 100 HU, which is currently recommended by the American College of Radiology, and the other with a narrow WW of 40 HU, both at a window level of 0 HU. For each case, technologists rated the presence of image artifacts based on a five point scale. The area under the receiver operating characteristic curve (AUC) was used to evaluate the artifact detection performance. At a WW of 100 HU, the AUC (95% confidence interval) was 0.658 (0.576, 0.740), 0.532 (0.429, 0.635), and 0.616 (0.543, 0.619) for the experienced, new, and all technologists, respectively. At a WW of 40 HU, the AUC was 0.768 (0.687, 0.850), 0.546 (0.433, 0.658), and 0.694 (0.619, 0.769), respectively. The performance significantly improved at WW of 40 HU for experienced technologists (p = 0.009) and for all technologists (p = 0.040). Use of a narrow display WW significantly improved technologists' performance in dQC for detecting subtle but clinically relevant artifacts as compared to that using a 100 HU display WW.

The nursing contribution to chronic disease management: a discussion paper.

Science.gov (United States)

Forbes, Angus; While, Alison

2009-01-01

This paper explores the nature of the nursing contribution to chronic disease management (CDM) and identifies a number of key nursing activities within CDM both at the individual patient and care system levels. The activities were identified following a detailed review of the literature (160 reports and studies of nursing practice) relating to three tracer disorders: diabetes, chronic obstructive pulmonary disease and multiple sclerosis. The paper examines these activities collectively to generate models expressing some of the core functions of nursing within CDM. The paper illustrates some of the changing characteristics of nursing roles within CDM. More fundamentally, the paper questions the position of nursing in relation to the technologies that define CDM systems and proposes four levels of contribution: the nurse as technology; the nurse as technologist; the nurse as system engineer; and the nurse as architect. These different levels reflect distinctions in the nature of the nursing gaze and power relations within the health care workforce. The paper also highlights how nurses are failing to develop the evidence for their practice in CDM. The paper concludes that there is a need for some clear principles to guide clinical practice and encourage innovation in CDM. It is argued that the principles should not be rule-bound but define a distinctive nursing gaze that will position the nursing profession within the health care system and in relation to other professions. The gaze should incorporate the needs of the individual patient and the care system that they inhabit.

Benthic reef primary production in response to large amplitude internal waves at the Similan Islands (Andaman Sea, Thailand)

KAUST Repository

Jantzen, Carin

2013-11-29

Coral reefs are facing rapidly changing environments, but implications for reef ecosystem functioning and important services, such as productivity, are difficult to predict. Comparative investigations on coral reefs that are naturally exposed to differing environmental settings can provide essential information in this context. One prevalent phenomenon regularly introducing alterations in water chemistry into coral reefs are internal waves. This study therefore investigates the effect of large amplitude internal waves (LAIW) on primary productivity in coral reefs at the Similan Islands (Andaman Sea, Thailand). The LAIW-exposed west sides of the islands are subjected to sudden drops in water temperature accompanied by enhanced inorganic nutrient concentrations compared to the sheltered east. At the central island, Ko Miang, east and west reefs are only few hundred meters apart, but feature pronounced differences. On the west lower live coral cover (-38%) coincides with higher turf algae cover (+64%) and growth (+54%) compared to the east side. Turf algae and the reef sand-associated microphytobenthos displayed similar chlorophyll a contents on both island sides, but under LAIW exposure, turf algae exhibited higher net photosynthesis (+23%), whereas the microphytobenthos displayed reduced net and gross photosynthesis (-19% and -26%, respectively) accompanied by lower respiration (-42%). In contrast, the predominant coral Porites lutea showed higher chlorophyll a tissues contents (+42%) on the LAIW-exposed west in response to lower light availability and higher inorganic nutrient concentrations, but net photosynthesis was comparable for both sides. Turf algae were the major primary producers on the west side, whereas microphytobenthos dominated on the east. The overall primary production rate (comprising all main benthic primary producers) was similar on both island sides, which indicates high primary production variability under different environmental conditions. �

This experiment was designed to determine the effect of litter provision and lining in nests and pecking and scratching areas on health and zootechnical performances. Research was carried out in furnished cages, each housing 60 beak-trimmed ISA Brown hens. Four different treatments were compared in a factorial arrangement, including 2 different nest linings (artificial turf versus plastic mesh), either used alone or combined with the use of litter (wheat bran) spread over the rubber mat in the pecking and scratching area (PSA). An additional treatment using artificial turf mat in the PSA and nests (as commonly used in commercial flocks) was used to compare the effect of PSA lining in the other treatments. Zootechnical performances (laying rate, egg weight, and feed intake) were unaffected by PSA lining or by nest lining. The use of artificial turf mats in the PSA resulted in less feather loss than rubber mats, especially on breast and cloaca/vent areas. No consequences were observed on BW or mortality. However, the use of plastic mesh in nests was seen to increase mortality in comparison with artificial turf mats, without affecting plumage condition and BW. Although wheat bran provision did not influence feed intake and laying rate, litter provision did result in slightly higher mean egg weight. Moreover, BW tended to be lower when litter was distributed in cages, and neck and breast plumage condition improved. The distribution of litter was not seen to have any effect on mortality. The provision of litter and the lining of the PSA and nests to improve the welfare of caged laying hens have an effect on mortality, plumage quality, and some zootechnical performances. These results show the importance of choosing the most suitable linings and litter to obtain the best possible compromise between the ethological needs of laying hens, zootechnical performance, and animal health.

Impact of urban heat island on cooling and environment: A demonstration project

International Nuclear Information System (INIS)

1993-04-01

Landscaping has been shown in simulation and field studies to reduce building cooling loads by affecting microclimatic factors such as solar radiation, wind speed and air temperature. A demonstration project was undertaken to determine the magnitude of landscape induced changes in microclimate on building cooling loads and water use on four typical residences in Phoenix, Arizona. The energy use and microclimate of three unlandscaped (bare soil, rock mulch) and one landscaped (turf) home were monitored during summer 1990. In the fall, turf was placed around one of the unlandscaped houses, and shade trees planted on the west and south sides of another. Measurements continued during the summer of 1991. Total house air conditioning and selected appliance electrical data were collected, as well as inside and outside air temperatures. Detailed microclimate measurements were obtained for one to two week periods during both summers. Maximum reductions of hourly outside air temperatures of 1 to 1.5 degrees C, and of daily average air temperatures of up to 1 degrees C, resulted from the addition of turf landscaping. Addition of small trees to the south and west sides of another treatment did not have a noticeable effect on air temperature. Cooling load reductions of 10% to 17% were observed between years when well-watered turf landscaping was added to a house previously surrounded by bare soil. Addition of small trees to another bare landscape did not produce a detectable change in cooling load. The results of the study are used as input to a standard building energy use simulation model to predict landscape effects on cooling load and water usage for three typical houses, and to develop guidelines for use of energy efficient residential landscapes in Phoenix, Arizona

2017-12-01

The American Association of Sleep Technologists (AAST) is the national membership organization representing sleep technologists. The Board of Directors of the AAST recognizes that changes in the workforce will result in an increased need for technologists with a higher level of education. In order to meet the needs of members, the AAST has: (1) convened a summit of stakeholders to discuss the changing landscape for sleep technologists; (2) hosted an educational task force to provide ongoing communication and support; and (3) commissioned a survey of members, educators and employers to better define educational gaps and opportunities for sleep technologists. This report summarizes the results of the survey and provides a roadmap for future educational development. Demographic information highlights the diversity of those in the field of sleep technology. The majority of respondents agree that new technical skills will be needed to achieve competence in sleep technology in the near future, but also that clinical and communication skills will be critical in expanding the role of the sleep technologist in the sleep center. These findings led the AAST leadership to propose new directions for the AAST in serving the needs of its members and the field of sleep technology. This will include a continued focus on education, both basic and advanced, and development of diverse pathways for senior sleep technologists as well as those just entering the field.

Effects of solar ultraviolet radiation on tropical algal communities

International Nuclear Information System (INIS)

Santas, R.

1989-01-01

This study assessed some of the effects of solar ultraviolet (UV) radiation ion coral reef algal assemblages. The first part of the investigation was carried out under controlled laboratory conditions in the coral reef microcosm at the National Museum of Natural History in Washington, D.C., while a field counterpart was completed at the Smithsonian Institution's marine station on Grand Turk, Turks and Caicos Islands, in the eastern Caribbean. The study attempted to separate the effects of UV-A from those of UV-B. In the laboratory, algal turf assemblages exposed to simulated solar UV radiation produced 55.1% less biomass than assemblages that were not exposed to UV. Assemblages not exposed to UV were dominated by Ectocarpus rhodochondroides, whereas in the assemblage developing under high UV radiation, Enteromorpha prolifera and eventually Schizothrix calcicola dominated. Lower UV-B irradiances caused a proportional reduction in biomass production and had less pronounced effects on species composition. UV-A did not have any significant effects on either algal turf productivity or community structure. In the field, assemblages exposed to naturally occurring solar UV supported a biomass 40% lower than that of assemblages protected from UV-B exposure. Once again, UV-A did not inhibit algal turf productivity

Practical solutions for staff recruitment & retention.

Science.gov (United States)

Vander Hoek, N

2001-01-01

There are three essential topics for radiology managers to consider in light of persistent staffing shortages: support of the profession and educational programs, perks as recruitment tools and incentives as retention tools. Some activities that can help support departments and educational programs for radiologic technologists are job shadowing, training for volunteer services, advanced placement for school applicants, sponsoring an educational program or clinical training site, creating a positive work environment and supporting outreach projects geared to local high schools. Traditional perks used in recruitment efforts have included relocation assistance, travel and lodging expenses during the interview process, loan repayment, scholarships and sign-on bonuses. Some common incentives for retaining employees are tuition reimbursement, cross training, availability of educational resources, continuing education opportunities, professional development and incremental increases in salary. There are many other tools that can be used, such as career ladders, creating an environment conducive to teamwork or a more personal atmosphere and showcasing talents of various staff members. There is much overlap among these suggestions in support of the profession and educational programs, recruitment and retention of qualified staff radiologic technologists. Radiology managers can and should be creative in developing different programs to build loyalty and commitment to a radiology department.

internal innovation processes. Open innovation incorporates processes such as 'user-led' (farmer and advisor) innovation and the 'co-development' (by technologists and users) of a technology. This strategy is increasingly used by a variety of organisations across sectors to try to ensure that the use of their outputs (products/services/technologies) is optimised by their target customers/clients, by incorporating user insights into the development of outputs. This research use the open innovation co-development framework through farmer and farm advisor focus group sessions to inform the development of a desirable software package for nutrient management planners (farm advisors) and desirable output formats for the end user (farmers).

Competency assessment of microbiology medical laboratory technologists in Ontario, Canada.

Science.gov (United States)

Desjardins, Marc; Fleming, Christine Ann

2014-08-01

Accreditation in Ontario, Canada, requires that licensed clinical laboratories participate in external quality assessment (also known as proficiency testing) and perform competency evaluation of their staff. To assess the extent of ongoing competency assessment practices, the Quality Management Program--Laboratory Services (QMP-LS) Microbiology Committee surveyed all 112 licensed Ontario microbiology laboratories. The questionnaire consisted of a total of 21 questions that included yes/no, multiple-choice, and short-answer formats. Participants were asked to provide information about existing programs, the frequency of testing, what areas are evaluated, and how results are communicated to the staff. Of the 111 responding laboratories, 6 indicated they did not have a formal evaluation program since they perform only limited bacteriology testing. Of the remaining 105 respondents, 87% perform evaluations at least annually or every 2 years, and 61% include any test or task performed, whereas 16% and 10% focus only on problem areas and high-volume complex tasks, respectively. The most common methods of evaluation were review of external quality assessment (EQA) challenges, direct observation, and worksheet review. With the exception of one participant, all communicate results to staff, and most take remedial action to correct the deficiencies. Although most accredited laboratories have a program to assess the ongoing competency of their staff, the methods used are not standardized or consistently applied, indicating that there is room for improvement. The survey successfully highlighted potential areas for improvement and allowed the QMP-LS Microbiology Committee to provide guidance to Ontario laboratories for establishing or improving existing microbiology-specific competency assessment programs.

This measurement and verification (M and V) protocol provides procedures for energy service companies (ESCOs) and water efficiency service companies (WESCOs) to determine water savings as a result of water conservation measures (WCMs) in energy performance contracts associated with converting turfgrass or other water-intensive plantings to water-wise and sustainable landscapes. The water savings are determined by comparing the baseline water use to the water use after the WCM has been implemented. This protocol outlines the basic structure of the M and V plan, and details the procedures to use to determine water savings.

Using Major Elements to Determine Sources of Nitrate in Groundwater, Suffolk County, Long Island, NY

Science.gov (United States)

Munster, J.; Hanson, G.; Bokuniewicz, H.

2004-05-01

Suffolk County is the eastern most county on Long Island with an area of 2,500 square kilometers and a population of 1.4 million. Groundwater is the only source of potable water for Suffolk County. Nitrate levels have become a concern as a result of the continued eastward urbanization of Long Island since the mid 1900's. In 2003, 2% of 1000 public supply wells had greater than 10 ppm nitrogen as nitrate, 8% had 6 to 10 ppm nitrogen as nitrate and 62% of the wells were rated as susceptible to increased nitrate contamination based on land use, travel time and prevalence. Nitrogen as nitrate above 10 ppm is harmful to infants and is currently the drinking water standard of the Environmental Protection Agency. The major sources of the nitrate in the urbanized areas are most likely turf grass fertilizer and sewage from septic tank/cesspool systems and sewage treatment plants that provide only secondary treatment. Turf grass occupies about 28% of the land. Two-thirds of the houses have septic tank/cesspool systems and a majority of the sewage treatment plants discharge effluent to the groundwater. Previous investigators of the sources of nitrate in groundwater on Long Island have used 15N values of nitrate-nitrogen to identify nitrate contamination (Bleifuss et al., 2000; Flipse and Bonner, 1985; Flipse et al., 1984; Kreitler et al., 1978). However, due to overlapping source signatures, nitrogen isotopes alone were not sufficient to characterize the sources of nitrate. More recent studies have shown that major elements that accompany nitrate in the groundwater (Bleifuss et al., 2000; Elhatip et al., 2003; Trauth and Xanthopoulos, 1997) may distinguish sources of nitrate with less ambiguity. In this study samples of waste water from septic tank/cesspool systems and sewage treatment plants and samples of soil water collected below turf grass that is not fertilized, fertilized with organic fertilizer and fertilized with chemical fertilizer were analyzed for major elements

Sonography can be highly dependent on real-time imaging and as such is highly physician intensive. Such situations arise mostly during complicated ultrasound radiology studies or echocardiology examinations. Under those circumstances it would be of benefit to transmit real-time images beyond the immediate area of the ultrasound laboratory when a physician is not on location. We undertook this study to determine if both static and dynamic image transfer to remote locations might be accomplished using an ultrafast ATM network and PACS. Image management of the local image files was performed by a commercial PACS from AGFA corporation. The local network was Ethernet based, and the global network was based on Asynchronous Transfer Mode (ATM, rates up to 100 Mbits/sec). Real-time image transfer involved two teaching hospitals, one of which had 2 separate ultrasound facilities. Radiologists consulted with technologists via telephone while the examinations were being performed. The applications of ATM network providing real time video for ultrasound imaging in a clinical environment and its potential impact on health delivery and clinical teaching. This technology increased technologist and physician productivity due to the elimination of commute time for physicians and waiting time for technologists and patients. Physician confidence in diagnosis increased compared to reviewing static images alone. This system provided instant access for radiologists to real-time scans from remote sites. Image quality and frame rate were equivalent to the original. The system increased productivity by allowing physicians to monitor studies at multiple sites simultaneously.

Education and career progression of imaging administrators.

Science.gov (United States)

South-Winter, Carole

2014-01-01

The advancement into leadership positions for many administrators began as staff technologists moving up via interim management opportunities. New managers must develop supervisory skills while simultaneously assuming responsibility for the operation of the department. Mobility today is based primarily on a formal educational background. A transferable set of skills must be augmented with higher education. Those in the imaging sciences realize that an administrative position requires business and management acumen as well as technical skills. A shortage of imaging administrators is predicted due to an aging population and the rapid advancement of technology in healthcare. Institutes of higher education need to address and support the curricula and programs needed, which includes the CRA credential, for this growing field.

Data management in an object-oriented distributed aircraft conceptual design environment

Science.gov (United States)

Lu, Zhijie

In the competitive global market place, aerospace companies are forced to deliver the right products to the right market, with the right cost, and at the right time. However, the rapid development of technologies and new business opportunities, such as mergers, acquisitions, supply chain management, etc., have dramatically increased the complexity of designing an aircraft. Therefore, the pressure to reduce design cycle time and cost is enormous. One way to solve such a dilemma is to develop and apply advanced engineering environments (AEEs), which are distributed collaborative virtual design environments linking researchers, technologists, designers, etc., together by incorporating application tools and advanced computational, communications, and networking facilities. Aircraft conceptual design, as the first design stage, provides major opportunity to compress design cycle time and is the cheapest place for making design changes. However, traditional aircraft conceptual design programs, which are monolithic programs, cannot provide satisfactory functionality to meet new design requirements due to the lack of domain flexibility and analysis scalability. Therefore, we are in need of the next generation aircraft conceptual design environment (NextADE). To build the NextADE, the framework and the data management problem are two major problems that need to be addressed at the forefront. Solving these two problems, particularly the data management problem, is the focus of this research. In this dissertation, in light of AEEs, a distributed object-oriented framework is firstly formulated and tested for the NextADE. In order to improve interoperability and simplify the integration of heterogeneous application tools, data management is one of the major problems that need to be tackled. To solve this problem, taking into account the characteristics of aircraft conceptual design data, a robust, extensible object-oriented data model is then proposed according to the

Competency Based Hospital Radiopharmacy Training. Additional Information

International Nuclear Information System (INIS)

2010-01-01

Quality management systems in nuclear medicine are vital to a high level of nuclear medicine (NM) practice. Trained and competent staffs are essential for achieving high standards and growth in NM. One of the key bottlenecks for NM is the shortfall in human resources, especially of radiopharmacists. There is an acute shortage in most Member States and in some countries an absence of nationally registered pharmacists with radiopharmacy experience. Most nuclear medicine facilities operate their radiopharmacies (commonly referred to as the hot laboratories) with the support of technologists and radiographers. Recent surveys have found the level of training amongst technologists to be extremely variable. Most had little or no training in hot laboratory practices. The survey also indicated the poor state of hot laboratories in many countries. Basic quality systems in the hot laboratory could be improved significantly with better training. This competency-based education manual is designed with those radiopharmacy practitioners in mind. This competency-based trainer's manual provides trainers in each of the IAEA regions with the essentials of a training programme for all radiopharmacy practitioners. The competency-based training is a two week programme followed up with three months of practice achievements. The syllabus provides a standardized approach to lectures, practical sessions, and interactive workshops focusing on critical aspects of hot laboratory practices. The trainers, with the assistance of this manual, can deliver essential skills, competencies, and underpinning knowledge to operate safely and effectively in their hot laboratory. The course focuses on simple but practical steps that could be undertaken to improve staff performance. In addition, a basic framework of quality management principles related to radiopharmacy practices is also covered. Further, the syllabus can be adapted to the particular needs and characteristics of any training centre, country

Because of the increase in healthcare-associated infections, appearance of highly resistant bacteria, and that of emerging/re-emerging infectious diseases, it is necessary for the skills of clinical microbiological technologists and the associated technology to be improved. Technologist in Microbiology (4,717 certified) and Specialist in Microbiology (58 certified) are authorized qualifications in the field of examination for clinical microbiology, with a history of 60 years, and Clinical Microbiological Technologist (670 certified) and Infection Control Microbiological Technologist (ICMT) (528 certified) are necessary qualifications to become a member of an infection control team. As problems to be resolved, clarifying the relationships among the authorized qualifications, reconsidering the fairness of evaluating written examinations, and further consideration of the administration method for an increasing number of examinees need to be tackled.

The influence of an artificial playing surface on injury risk and perceptions of muscle soreness in elite Rugby Union.

2016-01-01

This prospective cohort study investigated the influence of an artificial playing surface on injury risk and perceptions of muscle soreness in elite English Premiership Rugby Union players. Time loss (from 39.5 matches) and abrasion (from 27 matches) injury risk was compared between matches played on artificial turf and natural grass. Muscle soreness was reported over the 4 days following one match played on each surface by 95 visiting players (i.e., normally play on natural grass surfaces). There was a likely trivial difference in the overall injury burden relating to time-loss injuries between playing surfaces [rate ratio = 1.01, 90% confidence interval (CI): 0.73-1.38]. Abrasions were substantially more common on artificial turf (rate ratio = 7.92, 90% CI: 4.39-14.28), although the majority of these were minor and only two resulted in any reported time loss. Muscle soreness was consistently higher over the 4 days following a match on artificial turf in comparison with natural grass, although the magnitude of this effect was small (effect sizes ranging from 0.26 to 0.40). These results suggest that overall injury risk is similar for the two playing surfaces, but further surveillance is required before inferences regarding specific injury diagnoses and smaller differences in overall injury risk can be made. © 2015 John Wiley & Sons A/S.

Young male soccer players have been identified as a target group for injury prevention, but studies addressing trends and determinants of injuries within this group are scarce. The goal of this study was to analyze age-specific trends in hospital-treated upper extremity fractures (UEF) among boys playing soccer in the Netherlands and to explore associated soccer-related factors. Data were obtained from a national database for the period 1998-2009. Rates were expressed as the annual number of UEF per 1000 soccer players. Poisson's regression was used to explore the association of UEF with the number of artificial turf fields and the number of injuries by physical contact. UEF rates increased significantly by 19.4% in boys 5-10 years, 73.2% in boys 11-14 years, and 38.8% in boys 15-18 years old. The number of injuries by physical contact showed a significant univariate association with UEF in boys 15-18 years old. The number of artificial turf fields showed a significant univariate association with UEF in all age groups, and remained significant for boys aged 15-18 years in a multivariate model. This study showed an increase of UEF rates in boys playing soccer, and an independent association between artificial turf fields and UEF in the oldest boys. © 2014 John Wiley & Sons A/S.

Yoskowitz, Joshua; Clark, Morgan; Labrake, Scott; Vineyard, Michael

2015-10-01

We have developed an external beam facility for the 1.1-MV tandem Pelletron accelerator in the Union College Ion Beam Analysis Laboratory. The beam is extracted from an aluminum pipe through a 1 / 4 ' ' diameter window with a 7.5- μm thick Kapton foil. This external beam facility allows us to perform ion beam analysis on samples that cannot be put under vacuum, including wet samples and samples too large to fit into the scattering chamber. We have commissioned the new facility by performing proton induced X-ray emission (PIXE) analysis of several samples of environmental interest. These include samples of artificial turf, running tracks, and a human tooth with an amalgam filling. A 1.7-MeV external proton beam was incident on the samples positioned 2 cm from the window. The resulting X-rays were measured using a silicon drift detector and were analyzed using GUPIX software to determine the concentrations of elements in the samples. The results on the human tooth indicate that while significant concentrations of Hg, Ag, and Sn are present in the amalgam filling, only trace amounts of Hg appear to have leached into the tooth. The artificial turf and running tracks show rather large concentrations of a broad range of elements and trace amounts of Pb in the turf infill.

Conflicts on technical issues frequently involve disagreements between the public and the technologists. This paper summarizes the major characteristics of three groups of technologists and four groups of the public which lead to many of the disagreements. To advance the mores of making decisions involving complex science or technology, technologists should develop an understanding of what information is needed for decisions, of the need for two-way communication with the public, and to become responsible for the accuracy and honesty of risk communication messages

Impacts of land use and land cover on surface and air temperature in urban landscapes

Science.gov (United States)

Crum, S.; Jenerette, D.

2015-12-01

Accelerating urbanization affects regional climate as the result of changing land cover and land use (LCLU). Urban land cover composition may provide valuable insight into relationships among urbanization, air, and land-surface temperature (Ta and LST, respectively). Climate may alter these relationships, where hotter climates experience larger LULC effects. To address these hypotheses we examined links between Ta, LST, LCLU, and vegetation across an urban coastal to desert climate gradient in southern California, USA. Using surface temperature radiometers, continuously measuring LST on standardized asphalt, concrete, and turf grass surfaces across the climate gradient, we found a 7.2°C and 4.6°C temperature decrease from asphalt to vegetated cover in the coast and desert, respectively. There is 131% more temporal variation in asphalt than turf grass surfaces, but 37% less temporal variation in concrete than turf grass. For concrete and turf grass surfaces, temporal variation in temperature increased from coast to desert. Using ground-based thermal imagery, measuring LST for 24 h sequences over citrus orchard and industrial use locations, we found a 14.5°C temperature decrease from industrial to orchard land use types (38.4°C and 23.9°C, respectively). Additionally, industrial land use types have 209% more spatial variation than orchard (CV=0.20 and 0.09, respectively). Using a network of 300 Ta (iButton) sensors mounted in city street trees throughout the region and hyperspectral imagery data we found urban vegetation greenness, measured using the normalized difference vegetation index (NDVI), was negatively correlated to Ta at night across the climate gradient. Contrasting previous findings, the closest coupling between NDVI and Ta is at the coast from 0000 h to 0800 h (highest r2 = 0.6, P urbanized regions of southern California, USA decrease Ta and LST and spatial variation in LST, while built surfaces and land uses have the opposite effect.

Patient dose monitoring systems: A new way of managing patient dose and quality in the radiology department.

Science.gov (United States)

Fitousi, N

2017-12-01

Due to the upcoming European Directive (2013/59/EURATOM) and the increased focus on patient safety in international guidelines and regulations, Patient Dose Monitoring Systems, also called Dose Management Systems (DMS), are introduced in medical imaging departments. This article focusses on the requirements for a DMS, its benefits and the necessary implementation steps. The implementation of a DMS can be perceived as a lengthy, yet worthy, procedure: users have to select the appropriate system for their applications, prepare data collection, validate, perform configuration, and start using the results in quality improvement projects. A state of the art DMS improves the quality of service, ensures patient safety and optimizes the efficiency of the department. The gain is multifaceted: the initial goal is compliance monitoring against diagnostic reference levels. At a higher level, the user gets an overview of the performance of the devices or centers that are under his supervision. Error identification, generation of alerts and workflow analysis are additional benefits. It can also enable a more patient-centric approach with personalized dosimetry. Skin dose, size-specific dose estimates and organ doses can be calculated and evaluated per patient. A DMS is a powerful tool and essential for improved quality and patient care in a radiology department. It can be configured to the needs of medical physicists, radiologists, technologists, even for the management of the hospital. Collaboration between all health professionals and stakeholders, input-output validation and communication of findings are key points in the process of a DMS implementation.

The Belmont Forum, a coalition of science funding agencies from 15 countries, is supporting an 18-month effort to assess the state of international of e-infrastructures and data management so that global change data and information can be more easily and efficiently exchanged internationally and across domains. Ultimately, this project aims to address the Belmont "Challenge" to deliver knowledge needed for action to avoid and adapt to detrimental environmental change, including extreme hazardous events. This effort emerged from conclusions by the Belmont Forum that transformative approaches and innovative technologies are needed for heterogeneous data/information to be integrated and made interoperable for researchers in disparate fields, and for myriad uses across international, institutional, disciplinary, spatial and temporal boundaries. The project will deliver a Community Strategy and Implementation Plan to prioritize international funding opportunities and long-term policy recommendations on how the Belmont Forum can implement a more coordinated, holistic, and sustainable approach to funding and supporting global change research. The Plan is expected to serve as the foundation of future Belmont Forum funding calls for proposals in support of research science goals as well as to establish long term e-infrastructure. More than 120 scientists, technologists, legal experts, social scientists, and other experts are participating in six Work Packages to develop the Plan by spring, 2015, under the broad rubrics of Architecture/Interoperability and Governance: Data Integration for Multidisciplinary Research; Improved Interface between Computation & Data Infrastructures; Harmonization of Global Data Infrastructure; Data Sharing; Open Data; and Capacity Building. Recommendations could lead to a more coordinated approach to policies, procedures and funding mechanisms to support e-infrastructures in a more sustainable way.
