Shuttle Repair Tools Automate Vehicle Maintenance

Science.gov (United States)

2013-01-01

Successfully building, flying, and maintaining the space shuttles was an immensely complex job that required a high level of detailed, precise engineering. After each shuttle landed, it entered a maintenance, repair, and overhaul (MRO) phase. Each system was thoroughly checked and tested, and worn or damaged parts replaced, before the shuttle was rolled out for its next mission. During the MRO period, workers needed to record exactly what needed replacing and why, as well as follow precise guidelines and procedures in making their repairs. That meant traceability, and with it lots of paperwork. In 2007, the number of reports generated during electrical system repairs was getting out of hand-placing among the top three systems in terms of paperwork volume. Repair specialists at Kennedy Space Center were unhappy spending so much time at a desk and so little time actually working on the shuttle. "Engineers weren't spending their time doing technical work," says Joseph Schuh, an electrical engineer at Kennedy. "Instead, they were busy with repetitive, time-consuming processes that, while important in their own right, provided a low return on time invested." The strain of such inefficiency was bad enough that slow electrical repairs jeopardized rollout on several occasions. Knowing there had to be a way to streamline operations, Kennedy asked Martin Belson, a project manager with 30 years experience as an aerospace contractor, to co-lead a team in developing software that would reduce the effort required to document shuttle repairs. The result was System Maintenance Automated Repair Tasks (SMART) software. SMART is a tool for aggregating and applying information on every aspect of repairs, from procedures and instructions to a vehicle s troubleshooting history. Drawing on that data, SMART largely automates the processes of generating repair instructions and post-repair paperwork. In the case of the space shuttle, this meant that SMART had 30 years worth of operations

A Grounded Theory Study of Aircraft Maintenance Technician Decision-Making

Science.gov (United States)

Norcross, Robert

Aircraft maintenance technician decision-making and actions have resulted in aircraft system errors causing aircraft incidents and accidents. Aircraft accident investigators and researchers examined the factors that influence aircraft maintenance technician errors and categorized the types of errors in an attempt to prevent similar occurrences. New aircraft technology introduced to improve aviation safety and efficiency incur failures that have no information contained in the aircraft maintenance manuals. According to the Federal Aviation Administration, aircraft maintenance technicians must use only approved aircraft maintenance documents to repair, modify, and service aircraft. This qualitative research used a grounded theory approach to explore the decision-making processes and actions taken by aircraft maintenance technicians when confronted with an aircraft problem not contained in the aircraft maintenance manuals. The target population for the research was Federal Aviation Administration licensed aircraft and power plant mechanics from across the United States. Nonprobability purposeful sampling was used to obtain aircraft maintenance technicians with the experience sought in the study problem. The sample population recruitment yielded 19 participants for eight focus group sessions to obtain opinions, perceptions, and experiences related to the study problem. All data collected was entered into the Atlas ti qualitative analysis software. The emergence of Aircraft Maintenance Technician decision-making themes regarding Aircraft Maintenance Manual content, Aircraft Maintenance Technician experience, and legal implications of not following Aircraft Maintenance Manuals surfaced. Conclusions from this study suggest Aircraft Maintenance Technician decision-making were influenced by experience, gaps in the Aircraft Maintenance Manuals, reliance on others, realizing the impact of decisions concerning aircraft airworthiness, management pressures, and legal concerns

Data analyst technician: an innovative role for the pharmacy technician.

Science.gov (United States)

Ervin, K C; Skledar, S; Hess, M M; Ryan, M

2001-10-01

The development of an innovative role for the pharmacy technician is described. The role of the pharmacy technician was based on a needs assessment and the expertise of the pharmacy technician selected. Initial responsibilities of the technician included chart reviews, benchmarking surveys, monthly financial impact analysis, initiative assessment, and quality improvement reporting. As the drug-use and disease-state management (DUDSM) program expanded, pharmacist activities increased, requiring the expansion of data analyst technician (DAT) duties. These new responsibilities included participation in patient assessment, data collection and interpretation, and formulary enforcement. Most recently, technicians' expanded duties include maintenance of a physician compliance profiling database, quality improvement reporting and graphing, active role in patient risk assessment and database management for adult vaccination, and support of financial impact monitoring for other institutions within the health system. This pharmacist-technician collaboration resulted a threefold increase in patient assessments completed per day. In addition, as the DUDSM program continues to expand across the health system, an increase in DAT resources from 0.5 to 1.0 full-time equivalent was obtained. The role of the DAT has increased the efficiency of the DUDSM program and has provided an innovative role for the pharmacy technician.

Biomedical technicians play a major role in ensuring that equipment is functional. Following in-field observations and an online survey, a mobile application was developed to aid technicians in troubleshooting biomedical equipment. It was hypothesized that this application could be used to aid technicians in equipment repair, as modeled by repair of a pulse oximeter.Methods: To identify specific barriers to equipment repair and maintenance for biomedical technicians, an online survey was conducted to determine current practices and challenges. These findings were used to guide the development of a mobile application system that guides technicians through maintenance and repair tasks. A convenience sample of technicians in Ethiopia tested the application using a broken pulse oximeter task and following this completed usability and content validity surveys.Results: Fifty-three technicians from 13 countries responded to the initial survey. The results of the survey showed that technicians find equipment manuals most useful, but these are not easily accessible. Many do not know how to or are uncomfortable reaching out to human resources. Thirty-three technicians completed the broken pulse oximeter task using the application. All were able to appropriately identify and repair the equipment, and post-task surveys of usability and content validity demonstrated highly positive scores (Agree to Strongly Agree on both scales.Discussion: This research demonstrates the need for improved access to resources for technicians and shows that a mobile application can be used to address a gap in

Science and engineering technicians in the United States: characteristics of a redefined population, 1972

International Nuclear Information System (INIS)

Finn, M.G.

1978-02-01

The 1972 redefined population was distributed among 10 technician fields. Approximately 75% of the total were concentrated in four relatively large fields: computer programmers; draftsmen; electrical and electronic technicians; and technicians, other fields. Women accounted for 11% of all technicians. The average age of technicians in 1972 was 37. Whites comprised 94.8% of all technicians, while 3.0% were black. More technicians resided in the middle Atlantic region than in any other region. As a percentage of the civilian labor force, however, technicians were most heavily concentrated in the New England and mountain regions. The educational level of technicians was quite diverse: about one-third had no postsecondary education, about one-sixth had at least a bachelor's degree. About one-half fell somewhere between these extremes. Approximately 68% of all technicians reported some form of supplemental training outside formal educational institutions. This training was quite diverse. In 1972, unemployed technicians totaled 3.2% of the technician labor force. Fourteen percent of technicians reported employment outside their field, and 11% reported employment outside the 10 technician fields that constituted the focus of this report. The median annual earnings of technicians employed full-time in 1971 was approximately $10,400. Private companies employed 71% of the technicians; federal and state governments employed 12.4% and 7.4%, respectively. Most other technicians were employed by local government or nonprofit organizations. Implications for policy and planning are drawn. The statistics presented here indicate that the most commonly used assumptions about education--occupation linkages are grossly oversimplified. 5 figures, 44 tables

Training pharmacy technicians to administer immunizations.

Science.gov (United States)

McKeirnan, Kimberly C; Frazier, Kyle R; Nguyen, Maryann; MacLean, Linda Garrelts

To evaluate the effectiveness of an immunization training program for pharmacy technicians on technicians' self-reported confidence, knowledge, and number of vaccines administered. A one-group pre- and posttest study was conducted with certified pharmacy technicians from Albertsons and Safeway community pharmacies in Idaho. Thirty pharmacy technicians were recruited to participate in an immunization administration training program comprising a 2-hour home study and a 2-hour live training. Pharmacy technician scores on a 10-question knowledge assessment, responses on a pre- and posttraining survey, and number of immunizations administered in the 6-month period following the training were collected. Twenty-five pharmacy technicians completed the home study and live portions of the immunization training program. All 29 pharmacy technicians who took the home study assessment passed with greater than 70% competency on the first attempt. Technicians self-reported increased confidence with immunization skills between the pretraining survey and the posttraining survey. From December 2016 to May 2017, the technicians administered 953 immunizations with 0 adverse events reported. For the first time, pharmacy technicians have legally administered immunizations in the United States. Trained pharmacy technicians demonstrated knowledge of vaccination procedures and self-reported improved confidence in immunization skills and administered immunizations after participating in a 4-hour training program.

Elzinga, Kate; Tyreman, Neil; Ladak, Adil; Savaryn, Bohdan; Olson, Jaret; Gordon, Tessa

Functional recovery after peripheral nerve injury and surgical repair declines with time and distance because the injured neurons without target contacts (chronic axotomy) progressively lose their regenerative capacity and chronically denervated Schwann cells (SCs) atrophy and fail to support axon regeneration. Findings that brief low frequency electrical stimulation (ES) accelerates axon outgrowth and muscle reinnervation after immediate nerve surgery in rats and human patients suggest that ES might improve regeneration after delayed nerve repair. To test this hypothesis, common peroneal (CP) neurons were chronically axotomized and/or tibial (TIB) SCs and ankle extensor muscles were chronically denervated by transection and ligation in rats. The CP and TIB nerves were cross-sutured after three months and subjected to either sham or one hour 20Hz ES. Using retrograde tracing, we found that ES significantly increased the numbers of both motor and sensory neurons that regenerated their axons after a three month period of chronic CP axotomy and/or chronic TIB SC denervation. Muscle and motor unit forces recorded to determine the numbers of neurons that reinnervated gastrocnemius muscle demonstrated that ES significantly increased the numbers of motoneurons that reinnervated chronically denervated muscles. We conclude that electrical stimulation of chronically axotomized motor and sensory neurons is effective in accelerating axon outgrowth into chronically denervated nerve stumps and improving target reinnervation after delayed nerve repair. Possible mechanisms for the efficacy of ES in promoting axon regeneration and target reinnervation after delayed nerve repair include the upregulation of neurotrophic factors.

Trinoskey, P.A.; Fry, L.A.; Egbert, W.F.

2000-01-01

Over the last two decades, a significant trend in health and safety has been toward greater specialization. However, compartmentalization of health and safety disciplines often leads to an inequity in resources, especially when appropriations overemphasize one risk to the detriment of others. For example, overemphasis on radiological safety can create an imbalance in overall worker protection. A multidisciplinary technical can help restore the balance and provide for a healthier and safer work environment. The key advantages of a multidisciplinary health and safety technician include: Broad coverage of the work area by one technician, More diverse use of the technician pool, Better coverage for off-shift or nonstandard hours, Balance of risks because all hazards are considered, Integrated emergency response, Ownership, Less time of identify the correct person with the requisite skills. We have developed a new standard that establishes the training and related qualifications for a multidisciplinary health and safety technician. The areas of training and qualification that are addressed include elements of industrial hygiene, industrial safety, fire protection, electrical safety, construction safety, and radiation safety. The initial core training program ensures that individuals are trained to the performance of requirements of the job. Initial training is in five areas: Fundamentals, Hazard recognition, Hazard assessment, Hazards controls, Hazards minimization. Core training is followed by formal qualification on specific tasks, including ventilation surveys, air monitoring, noise assessments, radiological monitoring, area inspections, work-area setups, and work coverage. The new standard addresses not only training topics and requirements, but also guidance to ensure that performance objectives are met. The standard applies to technicians, supervisors, technologists, and six specialty areas, including academic institutions and decontamination and decommissioning

Calcium influx affects intracellular transport and membrane repair following nanosecond pulsed electric field exposure.

Science.gov (United States)

Thompson, Gary Lee; Roth, Caleb C; Dalzell, Danielle R; Kuipers, Marjorie; Ibey, Bennett L

2014-05-01

The cellular response to subtle membrane damage following exposure to nanosecond pulsed electric fields (nsPEF) is not well understood. Recent work has shown that when cells are exposed to nsPEF, ion permeable nanopores (2  nm) created by longer micro- and millisecond duration pulses. Nanoporation of the plasma membrane by nsPEF has been shown to cause a transient increase in intracellular calcium concentration within milliseconds after exposure. Our research objective is to determine the impact of nsPEF on calcium-dependent structural and repair systems in mammalian cells. Chinese hamster ovary (CHO-K1) cells were exposed in the presence and absence of calcium ions in the outside buffer to either 1 or 20, 600-ns duration electrical pulses at 16.2  kV/cm, and pore size was determined using propidium iodide and calcium green. Membrane organization was observed with morphological changes and increases in FM1-43 fluorescence. Migration of lysosomes, implicated in membrane repair, was followed using confocal microscopy of red fluorescent protein-tagged LAMP1. Microtubule structure was imaged using mEmerald-tubulin. We found that at high 600-ns PEF dosage, calcium-induced membrane restructuring and microtubule depolymerization coincide with interruption of membrane repair via lysosomal exocytosis.

This study aimed to investigate the opinions of pharmacists and technicians regarding the ability of New Zealand technicians to take on an advanced checking technician role. A survey was developed to investigate the opinions regarding the introduction of this new role. The questions covered are: perceived ability to take on the role, training requirements and competence. Surveys were sent to pharmacists whose contact details are available for research purposes (n = 2095) and to all pharmacies in New Zealand (both community and hospital) for the attention of technicians (n = 858). The results were analysed using IBM SPSS and thematic analysis of comments was conducted. A total of 1221 surveys were returned (pharmacists = 736 and technicians = 485). The majority of the technicians (83%) believed that 'some' technicians could work in a CT role, compared with 73% of the pharmacists. Over two-thirds (69%) of the technicians felt comfortable checking a prescription at their current level of training compared with 53% of pharmacists. Both groups' comfort increased with further specific training for the technicians. The majority of both of these groups supported the change in roles. Pharmacists were less confident that technicians could take on this role now, but were more comfortable after extra training had been completed. The technicians, however, were confident they could take on this role now but would take on extra training if needed. © 2015 Royal Pharmaceutical Society.

Pharmacy technician involvement in community pharmacy medication therapy management.

Lengel, Matthew; Kuhn, Catherine H; Worley, Marcia; Wehr, Allison M; McAuley, James W

To assess the impact of technician involvement on the completion of medication therapy management (MTM) services in a community pharmacy setting and to describe pharmacists' and technicians' perceptions of technician involvement in MTM-related tasks and their satisfaction with the technician's role in MTM. Prospective observational study. In the fall of 2015, pharmacists and selected technicians from 32 grocery store-based community pharmacies were trained to use technicians within MTM services. Completed MTM claims were evaluated at all pharmacies for 3 months before training and 3 months after training. An electronic survey, developed with the use of competencies taught in the training and relevant published literature, was distributed via e-mail to trained employees 3 months after training. The total number of completed MTM claims at the 32 pharmacy sites was higher during the posttraining time period (2687 claims) versus the pretraining period (1735 claims). Of the 182 trained participants, 112 (61.5%) completed the survey. Overall, perceived technician involvement was lower than expected. However, identifying MTM opportunities was the most commonly reported technician MTM task, with 62.5% of technicians and 47.2% of pharmacists reporting technician involvement. Nearly one-half of technicians (42.5%) and pharmacists (44.0%) agreed or strongly agreed they were satisfied with the technician's role in MTM services, and 40.0% of technicians agreed that they were more satisfied with their work in the pharmacy after involvement in MTM. Three months after initial training of technicians in MTM, participation of technicians was lower than expected. However, the technicians involved most often reported identifying MTM opportunities for pharmacists, which may be a focus for future technician trainings. In addition, technician involvement in MTM services may increase satisfaction with many aspects of work for actively involved technicians. Copyright © 2018 American

Technicians for the Brazilian nuclear power programme

Martins Pinto, C.S.; Spitalnik, J.; Meakins, E.J.; Hurley, I.

1980-01-01

The technician has a responsible role to fulfil in nuclear industry, acting as a bridge between the engineer and the skilled worker. Technicians must have sufficient theoretical knowledge to communicate with engineers, and a thorough understanding of technological practice; the nuclear industry demands both theory and practice of a high standard. In Brazil the essential role of the technician in industry is in general recognized. However, the lack of a nationally recognized Nuclear Technician and Nuclear Technologist qualification, as well as a desire of the best technicians to quality as engineers and, in some areas, inadequate salaries has resulted in a shortage of well-trained technicians. A first step to ensure availability of these technicians is to improve their career prospects and status through definition of appropriate career standards and salaries. Practical training by the industry can only be given in factories, plants and construction sites where nuclear work is done. It is proposed to extend apprentice training centres at three sites, to give the most promising students after two years of apprentice training two further years of instruction and practice to qualify as Nuclear Technicians. The training centres are chosen to cover the three sectors of nuclear industry where special training of technicians is important: manufacture and construction; operation and maintenance; and testing and analysis for process control and safety.

Hull, D.M.; Roney, M.W.

1975-01-01

An available and economical supply to future manpower requirements for various types of nuclear technicians can be met by developing and/or restructuring two-year, post-secondary programs at local educational institutions. The Technical Education Research Centers program is under contract from the U.S. Office of Education to delineate the job requirements and develop curricula and instructional materials for two-year, post-secondary training of nuclear technicians. Six job categories have been identified along with corresponding tasks which the technician performs. These categories are: Reactor Operator, Nuclear Instrumentation Technician, Nuclear QA/QC Technician, Radiochemistry Technician, Radiation Protection Technician and Nuclear Medicine Technician. For the first five categories curricula have been established, courses have been described, and instructional materials are being written

2004-01-01

To evaluate the knowledge and attitudes of pharmacy technicians before and after attending a continuing education program about smoking cessation. A pre/post survey of a single group. Two statewide meetings of the Iowa Pharmacy Association. Pharmacy technicians. One 2-hour continuing education (CE) course about smoking cessation for pharmacy technicians. Changes in scores before and after the CE sessions among three domains (knowledge, efficacy, and outcome) of a validated survey instrument. Fifty-one technicians completed both the presession and postsession questionnaire. For the three survey domains, technicians' knowledge (P = .034), efficacy (P < .001), and outcome (P < .001) showed significant improvement between the presession and postsession surveys (Wilcoxon signed rank test). Pharmacy technicians who attended a CE program on smoking cessation improved their knowledge, attitudes, and self-confidence in helping smokers quit. Additional research should be conducted to test the role of pharmacy technicians in smoking cessation promotion.

Lucas, Amber; Massey, Lindsay; Gill, Taylor; Burger, Gregory; Little, Jeff D

2016-02-01

The successful enactment of mandatory pharmacy technician certification in Kansas is described. In 2004, Kansas began requiring registration of all pharmacy technicians with the state board of pharmacy. Registration identified individuals working as pharmacy technicians but did not require any specific education or certification. In September 2012, the Kansas Board of Pharmacy created a task force of key stakeholders including pharmacists from multiple areas of practice, the University of Kansas School of Pharmacy, organizational leaders from the Kansas Council of Health-System Pharmacists (KCHP) and Kansas Pharmacists Association, and professional lobbyists. The goals of this task force were to research practices of technician certification in other states and to make recommendations to the state board of pharmacy on how Kansas could accomplish mandatory technician certification. The task force outlined the steps needed to achieve legislation that could be supported by the members. These topics included the creation of a technician trainee category, grandfathering certain technicians who had been practicing for a designated period of time, state board-approved exemptions, training requirements, age and education requirements, continuing-education requirements, and pharmacist:technician ratio. The recommendations were finalized at the August 2013 Kansas Pharmacy Summit, and the proposed legislation was introduced and passed during the 2014 legislative session. KCHP members learned many valuable lessons about advocacy and the legislative process with this initiative, including building relationships, working with legislators, and working with other professional organizations. The formation of a task force led to the successful passage of a bill granting the Kansas Board of Pharmacy the authority to issue regulations regarding mandatory pharmacy technician certification.

The process used in preparing this administrative report provided the means of documenting departmental support of technician task expansion, cost benefits, increased availability of professional time, and the need for a dynamic department. Some of the benefits to St. Luke's Regional Medical Center and its Pharmacy Department were an increase in technician job satisfaction, improved quality of patient care attributable to the increased scope of pharmacy service, and up to 8554 hours per year of professional time available for more clinically oriented responsibilities. If technician turnover were decreased by half, technician pricing errors eliminated, and technicians assumed the identified technical tasks, potential monetary benefits could be as much as +116,900 per year. The departmental cost of implementing these recommendations would be an additional 4.16 technician FTEs, and the professional time for training, supervising, and coordinating technicians and functions. These recommendations were well received by pharmacy administration, and the committee was asked to develop a list of priorities and an implementation plan for administrative approval.

Aplastic anemia in Japanese radiological technicians

Kitabatake, T.; Watanabe, T.; Saito, A.; Nakamura, M.; Shiohama Hospital, Mie

1976-01-01

Among the Japanese radiological technicians, four deaths from aplastic anemia have been reported after 1930. On the other hand, during the period from 1930 to 1960, the population of radiological technicians is estimated to be 74,400 man-years, in which 0.5 aplastic anemias are expected. However, actually three died from aplastic anemia. This difference is statistically significant at the 1% level. While, in the period from 1961 to 1973, the observed value is 1 against 0.7 expected. It is concluded that aplastic anemia had been induced frequently among the Japanese radiological technicians in the era when there was much exposure to occupational radiation. (orig.) [de

2004-01-01

In view of the known health hazards of x-ray radiation, this study focuses on the basic hematological parameters: red blood cells (RBCs), white blood cells (WBCs) and platelets count in x-ray technicians. The aim was to identify the affect of x-ray radiation on blood cell counts in x-ray technicians. The present study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the year 2002. In this study, a group of 40 apparently healthy male x-ray technicians with age ranging from 25-50-years were recruited. They were matched with another group of 40 apparently healthy control subjects in terms of age, sex and ethnic origin. Both groups met with exclusion criteria as per standard. Red blood cells, WBC and platelets count were performed by using a blood cell auto analyser. The mean value of platelet count was significantly decreased (p<0.01) in x-ray technicians when compared to controls. However, no significant difference was observed in RBC and WBC count between the groups. Radiation causes decreased platelet count. Further, studies are needed to study the long-term effects of x-ray radiation on blood cell count in x-ray technicians. (author)

Electrical Stimulation Elicit Neural Stem Cells Activation：New Perspectives in CNS Repair

Ratrel eHuang

2015-10-01

Full Text Available Researchers are enthusiastically concerned about neural stem cell (NSC therapy in a wide array of diseases, including stroke, neurodegenerative disease, spinal cord injury (SCI and depression. Although enormous evidences have demonstrated that neurobehavioral improvement may benefit from NSC-supporting regeneration in animal models, approaches to endogenous and transplanted NSCs are blocked by hurdles of migration, proliferation, maturation and integration of NSCs. Electrical stimulation (ES may be a selective nondrug approach for mobilizing NSCs in the central nervous system (CNS. This technique is suitable for clinic application, because it is well established and its potential complications are manageable. Here, we provide a comprehensive review of the emerging positive role of different electrical cues in regulating NSC biology in vitro and in vivo, as well as biomaterial-based and chemical stimulation of NSCs. In the future, ES combined with stem cell therapy or other cues probably becomes an approach for promoting brain repair.

U.S. photonics organizations need about 800 new photonics technicians each year. Thirty-one community and technical colleges have approximately 700 students enrolled in photonics related programs; about 275 of them complete their coursework and enter the workforce each year. A disparity exists between the demand and supply of qualified photonics technicians in the U.S. OP-TEC, the National Center for Optics and Photonics Education is a consortium of seven colleges, under the leadership of the University of Central Florida, and sponsored by NSF. OP-TEC's mission is to increase the quantity and quality of photonics technicians prepared at two-year colleges. OP-TEC maintains the National Photonics Skill Standards for Technicians, provides curriculum models, teaching materials, faculty training/professional development and planning services to strengthen existing college photonics programs and to attract and support new ones. OP-TEC is converting its text materials to E-Books to support students in technical programs. Through OP-TEC's recruitment efforts 84 additional colleges are interested in initiating new photonics programs. The OP-TEC Photonics College Network (OPCN) consists of 28 colleges that are currently providing photonics education. This fall OPCN will lead an additional national effort to further educate employed photonics technicians through on-line courses, complemented by lab experiences at nearby colleges. OP-TEC is expanding its outreach to photonics employers and colleges by regionalizing its approach to offering its services. OP-TEC is also planning to develop new curricula and instructional materials for AAS programs to prepare Precision Optics Technicians. This paper will detail OP-TEC's work with particular emphases on its materials and services.

Mattingly, Ashlee N; Mattingly, T Joseph

To summarize the findings of a literature search on advancing the role of pharmacy technicians, including the types of training identified and the potential costs and benefits to both the technician and the pharmacy. A literature search of Scopus, Embase, and Medline was conducted on January 11, 2017. Original research, research reports, case studies, or association reports were included for review. Articles were considered to be relevant based on identification of an advanced pharmacy technician role or addressing additional training/education for technician functions. A standard data extraction form was used to collect study authors, article title, year published, journal title, study design, brief description of methods, primary outcome measures, advanced technician roles identified, additional education or training addressed, and additional costs and benefits identified in each article. A total of 33 articles were included for full review and data extraction. Study design varied, with 17 (52%) quantitative, 1 (3%) qualitative, 5 (15%) mixed-method, and 10 (30%) case study designs. Seventeen (52%) of the studies included were published after 2006. The mechanism of training was primarily through supervised on-the-job training, allowing technicians to assume administrative-based positions that facilitated a pharmacist-led clinical service, with either the pharmacist or the pharmacy receiving the greatest benefits. Although the literature supports technicians performing advanced roles in the pharmacy, resulting in either improved patient outcomes or opportunities for pharmacists to engage in additional clinical services, the benefits to the technician were primarily indirect, such as an increase in job satisfaction or a more desirable work schedule. If a technician is to take on additional roles that require completion of a formalized training or educational program, benefits that are more tangible may help to inspire technicians to pursue these roles.

Studies on the topic of burnout measure the effects of emotional exhaustion (EE), depersonalization (DP) (negative or cynical attitudes toward work), and reduced sense of personal accomplishment (PA). While the prevalence of burnout in practicing emergency medicine (EM) professionals has been studied, little is known of the prevalence and factors across physicians, nurses, technicians, and health information technicians working for the same institution. The aim of this study was to assess burnout differences across EM professional types.The total population of 250 EM professionals at 2 public urban hospitals in Turkey were surveyed using the Maslach Burnout Inventory and basic social- and work-related demographics. Descriptive statistics, ANOVA, and additional post hoc tests were computed.Findings show that EE and DP scores were high across all occupational groups, while scores on PA were low. There was a statistically significant difference between nurses and medical technicians (P nurses and medical technicians (P Burnout can be high across occupational groups in the emergency department. Burnout is important for EM administrators to assess across human resources. Statistically significant differences across socio-demographic groups vary across occupational groups. However, differences between occupational groups may not be explained effectively by the demographic factors assessed in this or other prior studies. Rather, the factors associated with burnout are incomplete and require further institutional, cultural, and organizational analyses including differentiating between job tasks carried out by each EM job type.

Despite advances in surgery, patients with nerve injuries frequently have functional deficits. We previously demonstrated in a rat model that daily electrical muscle stimulation (EMS) following peripheral nerve injury and repair enhances reinnervation, detectable as early as two weeks post-injury. In this study, we explain the enhanced early reinnervation observed with electrical stimulation. In two groups of rats, the tibial nerve was transected and immediately repaired. Gastrocnemius muscles were implanted with intramuscular electrodes for sham or muscle stimulation. Muscles were stimulated daily, eliciting 600 contractions for one hour/day, repeated five days per week. Sixteen days following nerve injury, muscles were assessed for functional reinnervation by motor unit number estimation methods using electromyographic recording. In a separate cohort of rats, surgical and electrical stimulation procedures were identical but muscles and distal nerve stumps were harvested for molecular analysis. We observed that stimulated muscles had significantly higher motor unit number counts. Intramuscular levels of brain-derived and glial cell line-derived neurotrophic factor (BDNF and GDNF) mRNA were significantly upregulated in muscles that underwent daily electrical stimulation compared to those without stimulation. The corresponding levels of trophic factor mRNA within the distal stump were not different from one another, indicating that the intramuscular electrical stimulus does not modulate Schwann cell-derived trophic factor transcription. Stimulation over a three-month period maintained elevated muscle-derived GDNF but not BDNF mRNA. In conclusion, EMS elevates intramuscular trophic factor mRNA levels which may explain how EMS enhances neural regeneration following nerve injury. Copyright © 2016 IBRO. Published by Elsevier Ltd.

Advancing technician practice: Deliberations of a regulatory board.

Science.gov (United States)

Adams, Alex J

2018-01-01

In 2016, the Idaho State Board of Pharmacy (U.S.) undertook a major rulemaking initiative to advance pharmacy practice by broadening the ability of pharmacists to delegate tasks to pharmacy technicians. The new rules of the Board thus moved the locus of control in technician scope of practice from law to pharmacist delegation. Pharmacist delegation is individualistic and takes into account the individual technician's capabilities, the pharmacist's comfort level, facility policies, and the risk mitigation strategies present at the facility, among other factors. State law limits, by contrast, are rigid and can mean that pharmacists are unable to delegate tasks that are or could otherwise be within the abilities of their technicians. The expanded technician duties are in two domains: 1) medication dispensing support (e.g., tech-check-tech, accepting verbal prescriptions, transferring prescriptions, and performing remote data entry); and 2) technical support for pharmacist clinical services (e.g., administering immunizations). This commentary reviews the evidence behind these expanded duties, as well as the key regulatory decision points for each task. The Board's rules and approach may prove useful to other states and even other governing bodies outside the U.S. as they consider similar issues. Copyright © 2017 Elsevier Inc. All rights reserved.

In health care simulation, simulation technicians perform multiple tasks to support various educational offerings. Technician responsibilities and the tasks that accompany them seem to vary between centers. The objectives were to identify the range and frequency of tasks that technicians perform and to determine if there is a correspondence between what technicians do and what they feel their responsibilities should be. We hypothesized that there is a core set of responsibilities and tasks for the technician position regardless of background, experience, and type of simulation center. We conducted a prospective, survey-based study of individuals currently functioning in a simulation technician role in a simulation center. This survey was designed internally and piloted within 3 academic simulation centers. Potential respondents were identified through a national mailing list, and the survey was distributed electronically during a 3-week period. A survey request was sent to 280 potential participants, 136 (49%) responded, and 73 met inclusion criteria. Five core tasks were identified as follows: equipment setup and breakdown, programming scenarios into software, operation of software during simulation, audiovisual support for courses, and on-site simulator maintenance. Independent of background before they were hired, technicians felt unprepared for their role once taking the position. Formal training was identified as a need; however, the majority of technicians felt experience over time was the main contributor toward developing knowledge and skills within their role. This study represents a first step in defining the technician role within simulation-based education and supports the need for the development of a formal job description to allow recruitment, development, and certification.

2009-01-01

The purpose of this paper is to provide basic data in order to systematize the management of demand and supply of radiologic technicians, to pursue a fair regional distribution of educational institutions, and furthermore to keep reasonable medical treatment and fee. This research was carried out through the investigation of radiologic equipment and technicians according to the distribution of the population. We compared and analyzed the correlation between regional population, the number of clinics and hospitals, the number of medical imaging devices, and the number of radiologists and radiologic technicians in 5 cities without 'Gu' administrative units in 2008. 27,317 radiologic technicians have been produced since the administration of the national qualifying exam for radiologic technicians. About 18,000 radiologic technicians are currently working. There are 39 colleges or universities with Departments of Radiology and the admission quota is 2,120 students excluding one college. The ratio of radiologic equipment to radiologic technicians is 2.6 to 1. There is a dilemma in which some radiologic technicians fail to find appropriate jobs while some clinics or hospitals are in need of radiologic technicians. This dilemma is due to unreasonable regional discrepancies in pay system and welfare situation, and excessive profit-oriented recruiting system of clinics and hospitals. The increase of students of Radiologic Departments and approval of additional departments will end up with producing superfluous high academic degree holders, which is on the contrary to the government policy to produce more job opportunities. So the policy of increasing Radiologic Departments should be reconsidered.

One hundred and seventy-eight dental laboratory technicians and 69 non-exposed controls participated in an epidemiological respiratory study. Eight technicians who had a mean of 28 years grinding nonprecious metal alloys were diagnosed as having a simple pneumoconiosis by chest radiograph. Mean values for per cent predicted FVC and FEV1 were reduced among male nonsmoker technicians compared to male nonsmoker controls; after controlling for age, there was also a reduction in spirometry with increasing work-years. An industrial hygiene survey was conducted in 13 laboratories randomly selected from 42 laboratories stratified by size and type of operation in the Salt Lake City, Utah metropolitan area. Personal exposures to beryllium and cobalt exceeded the Threshold Limit Values (TLVs) in one laboratory. Occupational exposures in dental laboratories need to be controlled to prevent beryllium-related lung disorders as well as simple pneumoconiosis

A uniform approach for on-site training and qualification of health physics technicians

International Nuclear Information System (INIS)

Till, J.E.

1977-01-01

Estimates show that in the U.S. approx. 75% of the health physics technicians received their training through courses offered by their employer. The quality and the extent of this training vary considerably among nuclear facilities. This paper describes a uniform approach for on-site training and qualification of health physics technicians applicable to all nuclear facilities. The program consists of four levels of qualification: Health Physics Technician Trainee, Technician I, Technician II and Senior Technician. The training is divided into modules that are composed of formal lectures, practical factors, experience, and a comprehensive examination. The minimum time required from hiring of inexperienced trainees to qualification as Senior Technicians is approx. 24 months. A qualification guide lists each step a technician must complete in the training program and provides documentation which facilitates audits by internal and external groups. Although items in the program would differ between facilities, the program provides specific titles for technicians, based on their training and experience, which would be applicable throughout the nuclear industry.

Guidebook on the education and training of technicians for nuclear power

International Nuclear Information System (INIS)

1989-01-01

The IAEA Guidebook on the Education and Training of Technicians for Nuclear Power aims to assist Member States, especially the developing countries which are in the process of implementing, or intending to implement, a nuclear power programme, to understand and meet their requirements for qualified technicians in the most effective and efficient manner. It specifically seeks to assist policy makers and planners, as well as those designing and implementing education and training programmes. In this Guidebook, technician level occupations include those filled by technicians and higher level technicians (techniciens superieurs or technologists) and also by non-graduate engineers. The Guidebook complements the IAEA Guidebook on Manpower Development for Nuclear Power, as well as the IAEA Guidebook on the Qualification of Nuclear Power Plant Operations Personnel. The key objectives of this Guidebook are to describe: (1) the level and content of conventional education and training which a technician must have before nuclear oriented education and training can begin; (2) the level and content of nuclear oriented education and training; (3) measures to bridge the gap between the education and training acquired by technicians in the national technical schools (i.e. the level attained before upgrading) and the level of education and training qualifications needed for technicians to work in the nuclear power programme (i.e. the level attained after completion of nuclear oriented education and training). Valuable information on the national experiences of IAEA Member States in the education and training of technicians for nuclear power, as well as examples of such education and training from various Member States, are included in IAEA-TECDOC-526, which should be read in conjunction with the present text. 3 refs, 13 figs, 3 tabs

Chemistry technician performance evaluation program Palo Verde Nuclear Generating Station

Shawver, J.M.

1992-01-01

The Arizona Nuclear Power Project (ANPP), a three-reactor site located 50 miles west of Phoenix, Arizona, has developed and implemented a program for evaluating individual chemistry technician analytical performance on a routine basis. About 45 chemistry technicians are employed at the site, 15 at each operating unit. The technicians routinely perform trace level analyses for impurities of concern to PWRs. Each month a set of blind samples is provided by an outside vendor. The blind samples contain 16 parameters which are matrixed to approximate the PWR's primary and secondary cycles. Nine technicians receive the samples, three from each operating unit, and perform the required analyses. Acceptance criteria for successful performance on the blind parameters is based on the values found in the Institute of Nuclear Power Operations (INPO) Document 83-016, Revision 2, August 1989, Chemistry Quality Control Program. The goal of the program is to have each technician demonstrate acceptable performance on each of 16 analytical parameters. On completion of each monthly set, a summary report of all of the analytical results for the sample set is prepared. From the summary report, analytical bias can be detected, technician performance is documented, and overall laboratory performance can be evaluated. The program has been very successful at satisfying the INPO requirement that the analytical performance of each individual technician should be checked on at least a six-month frequency for all important parameters measured. This paper describes the program as implemented at the Palo Verde Nuclear Generating Station and provides a summary report and trend and bias graphs for illustrative purposes

The law for radiation and x-ray technicians engaging in medical treatment

International Nuclear Information System (INIS)

1977-01-01

The Law aims to define the qulifications of radiation and x-ray technicians engaging in medical treatment and to regulate so that the works are carried out properly for helping popularization and improvement of medicine and public hygiene. Persons who wish to be radiation or x-ray technicians engaging in medical treatment are required to pass the examinations for such technicians and obtain the licenes of the Minister of Health and Welfare for the former technicians and the license of a prefectural governor for the latter technicians. Mentally disordered, deaf, dumb or blind persons are excluded from licensees. Registration of such technicians, delivery of the license certificates and other related matters are provided for. The examinations are held concerning the knowledges and skills necessary for such technicians and carried out by the Minister of Health and Welfare. Persons except doctors, dentists and such technicians are prohibited to engage in the practices to apply radiation to human bodies. Restrictions on the intensity of radiation applied and the places of work are defined concerning such practices. Penal servitude of less than a year and fines less than yen 10,000 or yen 5,000 are imposed upon the violation of such prohibitions or restrictions. (Okada, K.)

2009-09-01

Outpatients undergoing hemodialysis are at high risk for adverse drug events. Limited resources make it challenging for pharmacists to routinely obtain a best possible medication history (BPMH). The primary objective was to determine whether, for patients undergoing hemodialysis, a pharmacy technician has the skills to obtain a BPMH that would allow a pharmacist to identify drug-related problems. The secondary objectives were to determine the number and types of medication discrepancies and drug-related problems identified and the time required by the technician to complete the BPMH. All patients treated in the hemodialysis unit during the study period were included, except for those who required an interpreter or were unable to participate in an in-person interview. A single technician was taught how to interview patients according to a structured format. For each patient, the technician's BMPH was verified by a pharmacist. The agreement rate between technician and pharmacists was determined, along with the number and types of discrepancies and drug-related problems identified. The technician interviewed 99 patients. Of the 1334 medication orders reviewed, the technician and pharmacists agreed on all but 15 (agreement rate 98.9%). A total of 358 medication discrepancies were noted for 93 patients (3.8 discrepancies per patient). Of these, 210 (59%) were undocumented intentional discrepancies, and 148 (41%) were unintentional discrepancies (most commonly errors of commission). Of the 135 drug-related problems identified, the majority involved dosing problems or nonadherence. The technician required an average of 17 min for each interview. An adequately trained technician was capable of interviewing patients to create a BPMH. A variety of medication discrepancies and drug-related problems were identified. Generation of a BPMH by a technician is a useful approach allowing pharmacists to identify drug-related problems.

To describe pharmacy technician training programs in the United States and to compare pharmacy technician program characteristics between programs with and without a pharmacist on faculty and between programs with different accreditation status. Descriptive, cross-sectional study. Not applicable. United States pharmacy technician programs. Not applicable. Student class size, faculty credentials, coursework components, program length, tuition rates, and admission criteria. Currently, there are more than 698 pharmacy technician programs across 1114 campuses, with complete data available for 216 programs. Programs varied widely in terms of class sizes, faculty credentials, and admission criteria. Programs with pharmacists on faculty were significantly less expensive than were those without pharmacists (P = 0.009). Accreditation had no impact on tuition prices. This is the first study of its kind to describe and characterize pharmacy technician training programs. There is relatively little control of technician training by the profession of pharmacy. The quality of these programs in terms of student outcomes is unknown, and it should be explored. Rigorous debate and discussion is needed regarding the future of pharmacy technician roles and the training required for those roles. Copyright © 2016 American Pharmacists Association®.

A reliability-based maintenance technicians' workloads optimisation model with stochastic consideration

Science.gov (United States)

Ighravwe, D. E.; Oke, S. A.; Adebiyi, K. A.

2016-06-01

The growing interest in technicians' workloads research is probably associated with the recent surge in competition. This was prompted by unprecedented technological development that triggers changes in customer tastes and preferences for industrial goods. In a quest for business improvement, this worldwide intense competition in industries has stimulated theories and practical frameworks that seek to optimise performance in workplaces. In line with this drive, the present paper proposes an optimisation model which considers technicians' reliability that complements factory information obtained. The information used emerged from technicians' productivity and earned-values using the concept of multi-objective modelling approach. Since technicians are expected to carry out routine and stochastic maintenance work, we consider these workloads as constraints. The influence of training, fatigue and experiential knowledge of technicians on workload management was considered. These workloads were combined with maintenance policy in optimising reliability, productivity and earned-values using the goal programming approach. Practical datasets were utilised in studying the applicability of the proposed model in practice. It was observed that our model was able to generate information that practicing maintenance engineers can apply in making more informed decisions on technicians' management.

Historically, the vital roles played by technicians in Higher Education have had little recognition. Job opportunities are often overlooked by those who have no working knowledge of such organisations and poorly defined career pathways mean that it may not be a first choice for well-qualified, ambitious individuals. With just over a third of all Higher Education technicians in the UK now due to retire in the next 10 to 15 years, fundamental changes are needed, both to attract large numbers of people into vacant roles and to retain current technical staff.National initiatives, founded and driven by charitable and professional bodies, are currently working to address the issues of technicians within Higher Education. Organisations have been urged to take action or face potential recruitment difficulties and skills gaps over the coming years. In light of these national campaigns, institutions across the UK are beginning to develop proper structured career pathways, provide professional development and improve recognition for the work of their technical workforce. Whilst these are encouraging signs, only time will tell if enough has been done to raise both the profile and appeal of a technical career in Higher Education.

Garcia-Gregory, J A; Jackson, A S; Studeville, J; Squires, W G; Owen, C A

1984-05-01

We evaluated the automated system Blood Pressure Measuring System (BPMS) developed by NASA on 277 adult males who elected to have a treadmill test as part of their annual physical. The BPMS uses acoustic transduction with a computer-assisted ECG gating to detect nonsynchronous noise. The BPMS readings were compared to pressures simultaneously measured by trained technicians. For all stages of work, BPMS readings were higher for systolic and lower for diastolic than technician readings. At peak stages of work, BPMS systolic pressures were about 20 mmHg higher than technician readings. Within each 3-min workstage, BPMS readings were found to be more inconsistent than technician readings. The standard errors of measurement for BPMS were from two to three times higher than technician values. These data showed automated blood pressure readings were significantly different than technician values and subject to more random fluctuations. These findings demonstrate the need to view exercise blood pressure measured by automated systems with caution.

The clinical experience and preferred learning style of U.S. Air Force flight nurses and aeromedical evacuation technicians are unknown. Using a cross-sectional survey design, we gathered data regarding the clinical experience, level of comfort providing clinical care, and preferred learning style of 77 active duty (AD), Air Force Reserve (AFR), and Air National Guard (ANG) nurses enrolled in the U.S. Air Force School of Aerospace Medicine Flight Nurse course, and 121 AD, AFR, and ANG medical technicians enrolled in the Aeromedical Evacuation Technician course. Nurses and medical technicians reported 7.6 ± 5.5 and 3.9 ± 4.5 yr of experience, respectively. AD, AFR, and ANG nurses had comparable years of experience: 5.8 ± 3.2, 8.3 ± 6.6, and 7.9 ± 4.2 yr, respectively; however, AD medical technicians had more years of experience (5.6 ± 4.4 yr) than AFR (3.1 ± 4.8 yr) and ANG (1.9 ± 2.8 yr) medical technicians. Both nurses and medical technicians reported infrequently caring for patients with various disease processes and managing equipment or devices that they will routinely encounter when transporting patients as an aeromedical evacuation clinician. Nurses and medical technicians preferred a kinesthetic learning style or a multimodal learning style that included kinesthetic learning. Nearly all (99%) nurses and 97% of medical technicians identified simulation as their preferred teaching method. These findings confirm faculty concerns regarding the clinical experience of flight nurse and aerospace evacuation technician students.De Jong MJ, Dukes SF, Dufour KM, Mortimer DL.

To describe the creation of a clinical pharmacy technician position within the U.S. Army and to identify the personal skills and characteristics required to meet the demands of this role. An outpatient military treatment facility located in Maryland. The clinical pharmacy technician position was designed to support clinical pharmacy services within a patient-centered medical home. Funding and a position description were established to hire a clinical pharmacy technician. Expected duties included administrative (45%), patient education (30%), and dispensing (25%). Local policy, in accordance with federal law and U.S. Army regulations, was developed to define the expanded technician responsibility to deliver patient medication education. In the initial 3 months, the clinical pharmacy technician spent 24 hours per week on clinical activities, affording an additional 10-15 hours per week for clinical pharmacists to provide patient care. Completed consults increased from 41% to 56%, and patient-pharmacist encounters increased from 240 to 290 per month. The technician, acting as a clinical pharmacist extender, also completed an average of 90 patient encounters independently each month. As a result of these improvements, the decision was made to hire a second technician. Currently, the technicians spend 28-40 hours per week on clinical activities, offsetting an average of 26 hours per week for the clinical pharmacists. A patient-centered medical home clinical pharmacy technician can reduce the administrative workload for clinical pharmacists, improve their efficiency, and enhance the use of clinical pharmacy services. Several characteristics, particularly medication knowledge, make pharmacy technicians particularly suited for this role. The results from the implementation of a clinical pharmacy technician at this military treatment facility resulted in an Army-wide expansion of the position and suggested applicability in other practice sites, particularly in federal

Management competencies required in the transition from a technician to a supervisor

Directory of Open Access Journals (Sweden)

Sibongile R. Mahlangu (Kubheka

2015-05-01

Full Text Available Orientation: Technicians are frequently promoted to supervisory positions based on their technical abilities, with scant attention focused on developing management competencies. This oversight often poses significant challenges. The effective transition from technician to supervisor is important in any organisation. Research objective: The primary objective is to identify and verify the competencies that are required for a technician and a supervisory position; the secondary objective is to identify the gap that must be filled with relevant training interventions to enable technicians to make an effective transition to a supervisory position. Motivation for this study: The identification of the management competencies required for a technician who makes a career change to a supervisor position. Research method: The sequential mixed method approach was used to enable the twophase data collection process: phase one was the quantitative phase and phase two was the qualitative phase. Main findings: The overall findings confirm that there are indeed management competencies that technicians require training and development on before being promoted to a supervisory position. Implication: Organisations need to identify the key competencies for a technician and a supervisor and implement development or training interventions that are essential to successfully transition an employee from the level of a technician to the level of a supervisor. Contribution: Organisations need to implement essential development or training interventions focused on developing management competencies and put in place support interventions such as coaching, job shadowing, mentoring and networking.

Perumal, Seena; Sehgal, Ashwini R

2003-10-01

The quality of hemodialysis care has been the focus of intense scrutiny, yet little is known about the job satisfaction of the nurses and technicians providing this care. We identified 240 nurses and technicians from 307 randomly selected American facilities and asked them about (a) specific domains of job satisfaction, (b) overall job satisfaction, and (c) self-reported patient care practices. Fewer than half of nurses and technicians were satisfied with their pay or their opportunities for advancement. Almost all subjects were satisfied with their personal delivery of patient care, their chance to do things for others, and their job security. About three-fourths of nurses and technicians expressed overall satisfaction with their jobs. Higher job satisfaction was associated with increased attention to patient psychosocial and educational needs. We urge local and national associations of nurses and technicians to collaborate with dialysis facilities, chains, and regulatory agencies to address specific aspects of job satisfaction.

Cooper, Julie B; Lilliston, Michelle; Brooks, DeAnne; Swords, Bruce

2014-09-15

The implementation and outcomes of a pharmacy technician medication history program are described. An interprofessional medication reconciliation team, led by a clinical pharmacist and a clinical nurse specialist, was charged with implementing a new electronic medication reconciliation system to improve compliance with medication reconciliation at discharge and capture compliance-linked reimbursement. The team recommended that the pharmacy department be allocated new pharmacy technician full-time-equivalent positions to assume ownership of the medication history process. Concurrent with the implementation of this program, a medication history standard was developed to define rules for documentation of what a patient reports he or she is actually taking. The standard requires a structured interview with the patient or caregiver and validation with outside sources as indicated to determine which medications to document in the medication history. The standard is based on four medication administration category rules: scheduled, as-needed, short-term, and discontinued medications. The medication history standard forms the core of the medication history technician training and accountability program. Pharmacy technicians are supervised by pharmacists, using a defined accountability plan based on a set of medical staff approved rules for what medications comprise a best possible medication history. Medication history accuracy and completeness rates have been consistently over 90% and rates of provider compliance with medication reconciliation rose from under 20% to 100% since program implementation. A defined medication history based on a medication history standard served as an effective foundation for a pharmacy technician medication history program, which helped improve provider compliance with discharge medication reconciliation.

The outcome of peripheral nerve injuries requiring surgical repair is poor. Recent work has suggested that electrical stimulation (ES) of denervated muscles could be beneficial. Here we tested whether ES has a positive influence on functional recovery after injury and surgical repair of the facial nerve. Outcomes at 2 months were compared to animals receiving sham stimulation (SS). Starting on the first day after end-to-end suture (facial-facial anastomosis), electrical stimulation (square 0.1 ms pulses at 5 Hz at an ex tempore established threshold amplitude of between 3.0 and 5.0V) was delivered to the vibrissal muscles for 5 min a day, 3 times a week. Restoration of vibrissal motor performance following ES or SS was evaluated using the video-based motion analysis and correlated with the degree of collateral axonal branching at the lesion site, the number of motor endplates in the target musculature and the quality of their reinnervation, i.e. the degree of mono- versus poly-innervation. Neither protocol reduced collateral branching. ES did not improve functional outcome, but rather reduced the number of innervated motor endplates to approximately one-fifth of normal values and failed to reduce the proportion of poly-innervated motor endplates. We conclude that ES is not beneficial for recovery of whisker function after facial nerve repair in rats.

Radiological Control Technician: Phase 4, Facility practical training attachment

International Nuclear Information System (INIS)

1992-10-01

At DOE sites with more than one facility, and where RCT tasks at each facility may differ, site and facility tasks should be separated. The tasks that are common to all the facilities on the site should be included in Phase II training with the core tasks. Tasks unique to a facility should be added to the training program qualification standard, as an attachment, as Phase IV training. Not all the DOE sites will include Phase IV training in their programs. Phase IV training allows each site to qualify technicians to a select facility. Since the core training for the technicians is standardized, the transfer of technicians between facilities requires that only facility tasks be taught, provided the core qualification is current

Dental laboratory technicians are at risk of developing occupational respiratory diseases due to exposure to various potentially toxic substances in their working environment. Since 1939, few cases of silicosis among dental technician have been reported. We illustrate a 38 year-old female, who worked in a dental laboratory for 20 years, initially treated as pulmonary tuberculosis and chronic necrotising aspergillosis without much improvement. Computed tomography guided lung biopsy and bronchoscopic transbronchial lung biopsy were performed. Lung tissue biopsies showed presence of refractile dental materials within the areas of histiocyte proliferation. The diagnosis of dental technician pneumoconiosis was obtained and our patient underwent pulmonary rehabilitation. This case highlights the importance of obtaining a detailed occupational history in tuberculosis endemic area, as pulmonary tuberculosis is a great mimicker of other respiratory diseases.

ASHP statement on the pharmacy technician's role in pharmacy informatics.

Science.gov (United States)

2014-02-01

The American Society of Health- System Pharmacists (ASHP) believes that specially trained pharmacy technicians can assume important supportive roles in pharmacy informatics. These roles include automation and technology systems management, management of projects, training and education, policy and governance, customer service, charge integrity, and reporting. Such roles require pharmacy technicians to gain expertise in information technology (IT) systems, including knowledge of interfaces, computer management techniques, problem resolution, and database maintenance. This knowledge could be acquired through specialized training or experience in a health science or allied scientific field (e.g., health informatics). With appropriate safeguards and supervision, pharmacy technician informaticists (PTIs) will manage IT processes in health-system pharmacy services, ensuring a safe and efficient medication-use process.

The ability of a pharmacy technician to support the patient screening and documentation-related functions of a pharmacist-driven osteoporosis management service was evaluated. A two-phase prospective study was conducted within a large integrated health system to assess a pharmacy technician's performance in supporting a multisite team of clinical pharmacy specialists providing postfracture care. In phase I of the study, a specially trained pharmacy technician provided support to pharmacists at five participating medical offices, helping to identify patients requiring pharmacist intervention and, when applicable, collecting patient-specific clinical information from the electronic health record. In phase II of the study, the amount of pharmacist time saved through the use of technician support versus usual care was evaluated. The records of 127 patient cases were reviewed by the pharmacy technician during phase I of the study, and a pharmacist agreed with the technician's determination of the need for intervention in the majority of instances (92.9%). An additional 91 patient cases were reviewed by the technician in phase II of the research. With technician support, pharmacists spent less time reviewing cases subsequently determined as not requiring intervention (mean ± S.D., 5.0 ± 3.8 minutes per case compared with 5.2 ± 4.5 minutes under the usual care model; p = 0.78). In cases requiring intervention, technician support was associated with a reduction in the average pharmacist time spent on care plan development (13.5 ± 7.1 minutes versus 18.2 ± 16.6 minutes with usual care, p = 0.34). The study results suggest that a pharmacy technician can accurately determine if a patient is a candidate for pharmacist intervention and collect clinical information to facilitate care plan development.

The roles of pharmacy technicians are increasingly prominent given pharmacy's transition to patient-centered activities and evolving scopes of practice in many U.S. states and throughout the world. The aims of this study were to assess U.S. pharmacy technicians' self-efficacies for and attitudes toward performing current and emerging roles in hospital and in community pharmacy and to identify factors related to pharmacy technician self-efficacies in these roles. A total of 5000 pharmacy technicians from 8 U.S. states were sent an electronic survey eliciting data on current involvement, self-efficacies, and attitudes for practicing in an expansive list of practice activities. The 8 states from which the sample was drawn were selected from a stratified randomized procedure using U.S. Census Bureau geographically defined regions. Pre-notification and response reminders were employed. Data were analyzed descriptively and with univariate, inferential tests, as appropriate, to determine associations with commitment, practice environment, experience level, and other variables. Of the 612 participants who responded, 494 were currently working as a technician and not enrolled in a PharmD program of study. Participants reported various activities in which they were highly engaged. Overall, attitudes toward performing most of the activities and self-efficacies were quite favorable, even for those activities in which technicians were currently less involved. There were some notable differences between technicians practicing in community versus hospital settings. Years of experience, profession commitment, and advanced employee ranking were associated with higher levels of self-efficacy, overall. This initial examination of pharmacy technician self-efficacies identified areas that along with other factors could help employers with further expanding technician practice activities and vocational institutions with considerations for education and development of these key members

Full Text Available Background: Dental laboratory technician is one of the professions in which dust exposure is frequently experienced and therefore the health of workers has to be monitored. Aims: In this study, changes in the pulmonary functions and of pneumoconiosis frequencies among dental technicians after five years were investigated by comparing the results of two screenings carried out in 2008 and 2013. Study Design: Cohort study. Methods: In 2008 and 2013, Provincial Health Directorate carried out two different health screenings covering all of the dental technicians working in dental laboratories in Denizli. In both screenings, a questionnaire was applied, with which socio-demographic and workplace properties of the technicians were obtained. In addition, Pulmonary function tests (PFT and standard chest X-rays of the technicians were performed. The results of these two screenings were evaluated by a chest specialist, and physical examinations were performed as necessary. In 2013, technicians who had pathologies underwent computerized tomography (HRCT. In this study, the study group was composed of dental laboratory technicians that participated in both screenings (2008 and 2013 and the data obtained from the screenings were compared. The gathered data were analyzed using paired student-t and X2 tests. Results: A total of 125 dental laboratory technicians participated in the two screenings. Overall, 92% of the technicians were male and the mean age of the participants was 35. Technicians were working for 9 hours a day, 6 days a week. Total exposure time was calculated to be around 41 thousand hours. Approximately 60% of workers were smokers. When the results of PFT were analyzed, 73% of the first evaluations were found to be normal; however, this ratio decreased to 51% in the second analysis five years later. In the second PFT measurement, compared to the first, there was a 23% decrease in the forced vital capacity (FVC value, and a 15.7% decrease in

Magnox reactors, although designed to be maintenance free during their operational life, have nevertheless highlighted the need for test rig facilities to train operators in the methods and techniques of reactor inspection and repair. The history of the facility for reactor engineering development (FRED) is described and its present role as a repair rehearsal facility noted. Advances in computer graphics may, in future, mean that such operator training will be virtual reality rather than analog reality based; however the need for such rigs to commission techniques and equipment and to establish performance and reliability is likely to continue.

Four transcranial magnetic stimulation (TMS) devices are currently approved for use in treatment-resistant depression. The authors present the first data-driven study examining the patient- and technician-experience using three of these distinct devices. A retrospective survey design with both patient and technician arms was utilized. The study population included patients who received TMS for treatment-resistant depression at the Berenson Allen Center for Noninvasive Brain Stimulation for the first time between 2013 and 2016 and technicians who worked in the program from 2009 to 2017. Statistical analysis included t tests and analyses of variance to assess differences between and across the multiple groups, respectively. Patients treated with the NeuroStar device reported greater confidence that the treatment was being performed correctly compared with those treated with the Magstim device. Conversely, with regard to tolerability, patients treated with the Magstim device reported less pain in the last week and less pain on average compared with those treated with the NeuroStar device. On average, technicians reported feeling that both the Magstim and NeuroStar devices were significantly easier to use than the Brainsway Deep TMS H-Coil device. Additionally, they found the former two devices to be more reliable and better tolerated. Furthermore, the technicians reported greater confidence in the Magstim and NeuroStar devices compared with the Brainsway Deep TMS H-Coil device and indicated that they would be more likely to recommend the two former devices to other treatment centers.

To discuss the policy of pharmacy technician-to-pharmacist ratios by comparing Florida as an example of legislative-led authority versus Tennessee as an example of board of pharmacy-led ruling. Over the past 2 years, the Florida legislature has debated the issue of pharmacy staffing ratios, initially leaving the Florida Board of Pharmacy with little authority to advocate for and enact safe technician staffing ratios. Anticipating this situation, the Tennessee Board of Pharmacy created rules to meet pharmacy staffing needs while protecting the authority of the pharmacist-in-charge and promoting patient safety. Before enacting rules, members of the board toured the state and talked about proposed rule changes with pharmacists. The final rule sets the pharmacy technician-to-pharmacist ratio at 2:1 but permits a 4:1 ratio based on public safety considerations and availability of at least two Certified Pharmacy Technicians. Pharmacists and leaders within the profession should conduct further research on appropriate and safe ratios of pharmacy technicians to pharmacists, with a focus on safety and quality of care.

Anderson, Vivienne R; Pang, Lilian C Y; Aarts, John M

2012-06-01

Under the 2003 Health Practitioners Competence Assurance (HPCA) Act, New Zealand registered dental technicians are subject to mandatory Continuing Professional Development (CPD) requirements. Internationally, little published literature has examined dental technicians' perspectives of CPD and CPD needs, and there is no published literature relating to the New Zealand context. Available research highlights the importance of CPD for maintaining high professional standards, ensuring patient safety, allowing dental technicians to keep abreast of current research and technological advances, fostering peer networks, and promoting job satisfaction. In 2009, an online open-ended questionnaire was developed to examine New Zealand dental and clinical dental technicians' perspectives of CPD and their perceived CPD needs. In total, 45 New Zealand registered dental technicians responded. Questionnaire responses provided rich qualitative insights into dental technicians' wide-ranging perceptions of CPD, factors that make CPD involvement more or less difficult and more or less desirable, and ways in which CPD access and relevance might be improved. This paper discusses the survey findings in the light of the existing literature on CPD and in relation to the unique New Zealand regulatory environment. It highlights the factors which respondents identified as shaping their CPD decisions, barriers to CPD engagement, perceived CPD needs, suggestions as to how the current CPD system could be improved, and areas for future research.

As surgery needs have increased, the traditional surgical team has expanded to include personnel from radiology and perfusion services. A new surgical team member, the intraoperative monitoring technician, is needed to perform intraoperative monitoring during procedures that carry a higher risk of central and peripheral nerve injury. Including the intraoperative monitoring technician on the surgical team can create challenges, including surgical delays and anesthesia care considerations. When the surgical team members, including the surgeon, anesthesia care provider, and circulating nurse, understand and facilitate this new staff member's responsibilities, the technician is able to perform monitoring functions that promote the smooth flow of the surgical procedure and positive patient outcomes.

Training and qualification of health and safety technicians at a national laboratory

International Nuclear Information System (INIS)

Egbert, W.F.; Trinoskey, P.A.

1994-10-01

Over the last 30 years, Lawrence Livermore National Laboratory (LLNL) has successfully implemented the concept of a multi-disciplined technician. LLNL Health and Safety Technicians have responsibilities in industrial hygiene, industrial safety, health physics, as well as fire, explosive, and criticality safety. One of the major benefits to this approach is the cost-effective use of workers who display an ownership of health and safety issues which is sometimes lacking when responsibilities are divided. Although LLNL has always promoted the concept of a multi-discipline technician, this concept is gaining interest within the Department of Energy (DOE) community. In November 1992, individuals from Oak Ridge Institute of Science and Education (ORISE) and RUST Geotech, joined by LLNL established a committee to address the issues of Health and Safety Technicians. In 1993, the DOE Office of Environmental, Safety and Health, in response to the Defense Nuclear Facility Safety Board Recommendation 91-6, stated DOE projects, particularly environmental restoration, typically present hazards other than radiation such as chemicals, explosives, complex construction activities, etc., which require additional expertise by Radiological Control Technicians. They followed with a commitment that a training guide would be issued. The trend in the last two decades has been toward greater specialization in the areas of health and safety. In contrast, the LLNL has moved toward a generalist approach integrating the once separate functions of the industrial hygiene and health physics technician into one function

To quantify consistency of endothelial cell density (ECD) measurements among technicians in a single US eye bank operating under typical operating conditions. In this retrospective analysis of 51 microscopy technicians using a semiautomated counting method on 35,067 eyes from July 2007 to May 2015, technician- and date-related marginal ECD effects were calculated using linear regression models. ECD variance was correlated with the number of specular microscopy technicians. Technician mean ECDs ranged from 2386 ± 431 to 3005 ± 560 cells/mm. Nine technicians had statistically and clinically significant marginal effects. Annual mean ECDs adjusted for changes in technicians ranged from 2422 ± 433 to 2644 ± 430 cells/mm. The period of 2007 to 2009 had statistically and clinically significant marginal effects. There was a nonstatistically significant association between the number of technicians and ECD standard deviation. There was significant ECD variability associated with specular microscopy technicians and with the date of measurement. We recommend that eye banks collect data related to laboratory factors that have been shown to influence ECD variability.

Pharmacist and Technician Perceptions of Tech-Check-Tech in Community Pharmacy Practice Settings.

Science.gov (United States)

Frost, Timothy P; Adams, Alex J

2018-04-01

Tech-check-tech (TCT) is a practice model in which pharmacy technicians with advanced training can perform final verification of prescriptions that have been previously reviewed for appropriateness by a pharmacist. Few states have adopted TCT in part because of the common view that this model is controversial among members of the profession. This article aims to summarize the existing research on pharmacist and technician perceptions of community pharmacy-based TCT. A literature review was conducted using MEDLINE (January 1990 to August 2016) and Google Scholar (January 1990 to August 2016) using the terms "tech* and check," "tech-check-tech," "checking technician," and "accuracy checking tech*." Of the 7 studies identified we found general agreement among both pharmacists and technicians that TCT in community pharmacy settings can be safely performed. This agreement persisted in studies of theoretical TCT models and in studies assessing participants in actual community-based TCT models. Pharmacists who had previously worked with a checking technician were generally more favorable toward TCT. Both pharmacists and technicians in community pharmacy settings generally perceived TCT to be safe, in both theoretical surveys and in surveys following actual TCT demonstration projects. These perceptions of safety align well with the actual outcomes achieved from community pharmacy TCT studies.

Component-Level Electronic-Assembly Repair (CLEAR) Spacecraft Circuit Diagnostics by Analog and Complex Signature Analysis

Science.gov (United States)

Oeftering, Richard C.; Wade, Raymond P.; Izadnegahdar, Alain

2011-01-01

The Component-Level Electronic-Assembly Repair (CLEAR) project at the NASA Glenn Research Center is aimed at developing technologies that will enable space-flight crews to perform in situ component-level repair of electronics on Moon and Mars outposts, where there is no existing infrastructure for logistics spares. These technologies must provide effective repair capabilities yet meet the payload and operational constraints of space facilities. Effective repair depends on a diagnostic capability that is versatile but easy to use by crew members that have limited training in electronics. CLEAR studied two techniques that involve extensive precharacterization of "known good" circuits to produce graphical signatures that provide an easy-to-use comparison method to quickly identify faulty components. Analog Signature Analysis (ASA) allows relatively rapid diagnostics of complex electronics by technicians with limited experience. Because of frequency limits and the growing dependence on broadband technologies, ASA must be augmented with other capabilities. To meet this challenge while preserving ease of use, CLEAR proposed an alternative called Complex Signature Analysis (CSA). Tests of ASA and CSA were used to compare capabilities and to determine if the techniques provided an overlapping or complementary capability. The results showed that the methods are complementary.

Fera, Toni; Kanel, Keith T; Bolinger, Meghan L; Fink, Amber E; Iheasirim, Serah

2018-02-01

The creation of a clinical support role for a pharmacy technician within a primary care resource center is described. In the Primary Care Resource Center (PCRC) Project, hospital-based care transition coordination hubs staffed by nurses and pharmacist teams were created in 6 independent community hospitals. At the largest site, patient volume for targeted diseases challenged the ability of the PCRC pharmacist to provide expected elements of care to targeted patients. Creation of a new pharmacy technician clinical support role was implemented as a cost-effective option to increase the pharmacist's efficiency. The pharmacist's work processes were reviewed and technical functions identified that could be assigned to a specially trained pharmacy technician under the direction of the PCRC pharmacist. Daily tasks performed by the pharmacy technician included maintenance of the patient roster and pending discharges, retrieval and documentation of pertinent laboratory and diagnostic test information from the patient's medical record, assembly of patient medication education materials, and identification of discrepancies between disparate systems' medication records. In the 6 months after establishing the PCRC pharmacy technician role, the pharmacist's completion of comprehensive medication reviews (CMRs) for target patients increased by 40.5% ( p = 0.0223), driven largely by a 42.4% ( p technician to augment pharmacist care in a PCRC team extended the reach of the pharmacist and allowed more time for the pharmacist to engage patients. Technician support enabled the pharmacist to complete more CMRs and reduced the time required for chart reviews. Copyright © 2018 by the American Society of Health-System Pharmacists, Inc.

Expanded pharmacy technician roles: Accepting verbal prescriptions and communicating prescription transfers.

Science.gov (United States)

Frost, Timothy P; Adams, Alex J

2017-11-01

As the role of the clinical pharmacist continues to develop and advance, it is critical to ensure pharmacists can operate in a practice environment and workflow that supports the full deployment of their clinical skills. When pharmacy technician roles are optimized, patient safety can be enhanced and pharmacists may dedicate more time to advanced clinical services. Currently, 17 states allow technicians to accept verbal prescriptions called in by a prescriber or prescriber's agent, or transfer a prescription order from one pharmacy to another. States that allow these activities generally put few legal limitations on them, and instead defer to the professional judgment of the supervising pharmacist whether to delegate these tasks or not. These activities were more likely to be seen in states that require technicians to be registered and certified, and in states that have accountability mechanisms (e.g., discipline authority) in place for technicians. There is little evidence to suggest these tasks cannot be performed safely and accurately by appropriately trained technicians, and the track record of success with these tasks spans four decades in some states. Pharmacists can adopt strong practice policies and procedures to mitigate the risk of harm from verbal orders, such as instituting read-back/spell-back techniques, or requiring the indication for each phoned-in medication, among other strategies. Pharmacists may also exercise discretion in deciding to whom to delegate these tasks. As the legal environment becomes more permissive, we foresee investment in more robust education and training of technicians to cover these activities. Thus, with the adoption of robust practice policies and procedures, delegation of verbal orders and prescription transfers can be safe and effective, remove undue stress on pharmacists, and potentially free up pharmacist time for higher-order clinical care.

Training needs analysis for engineering technicians in Oman

Science.gov (United States)

Al-Mughairi, Abdulkarim Sultan

This thesis examines the transition from the Omani Colleges of Technology (CT) to employment of its engineering graduates. It arises out of concerns that the transition to the labour market for engineering graduate is problematical. The research was carried out to identify the knowledge, skills, and abilities (KSA) of engineering technicians required in the Omani market place. The aim is to provide local curriculum designers in the Colleges of Technology with sufficient information about the required KSA in order to create and enhance the engineering curriculum so that it has greater capacity to meet the needs of a variety of stakeholders and of employers in particular. This in turn has the potential to bridge the gap between what is presently taught and what the workplace demands. Personnel psychologists identify views concerning the skills that are required for different jobs. One of these is based on the assumption that quite different skills are required in different jobs (SCANS, 1990). This view generates approaches within job analysis: the worker-oriented and the task-oriented approaches. This research uses Position Analysis Questionnaire (PAQ), which is a worker-oriented job analysis instrument, to investigate the KSA required to perform some of the engineering technician jobs in Omani industries. In addition, semi-structured interviews were used to investigate the factors that either hinder or entirely prevent the new graduates from Colleges of Technology from being accepted in the workforce pool. The major research findings concern the dimensions of knowledge, skills, and abilities of six engineering technician job titles and the major factors that hinder or (prevent) the technical college graduates from being accepted in the market place in Oman. These findings would definitely help design better transition route and bridge the gap between the CT technicians engineering programmes and the workplace demands.

THE ROLE OF SCHOOL TECHNICIANS IN PROMOTING SCIENCE THROUGH PRACTICAL WORK

Directory of Open Access Journals (Sweden)

Anne T. Helliar

2011-11-01

Full Text Available This is a review of the role of practical work in UK’s secondary school science lessons, the impact that practical work has in the promotion of science, the challenges created through use of non-specialist science teachers and a possible additional role for science technicians. The paper considers how improved deployment of suitably experienced school science technicians and their recognition, by schools’ management, for their involvement in the delivery of training in the use of practical work, for less experienced teachers, could benefit schools and their students. This together with its companion paper endeavours to show how the more effective use of practical work and technicians can encourage more students to select science at higher, non-compulsory levels.

To determine occupational association with metabolic syndrome among auto technicians and school teachers. One hundred and sixty six subjects were selected for this study. Clinical data was obtained while laboratory investigations including plasma glucose and lipid profile were performed. Statistical analysis was done with SPSS 20.0. Pauto technicians. Mean serum triglycerides was significantly higher among auto-technicians compared to school teachers in this study. The prevalence of some conventional cardiovascular risk factors was significantly higher among auto-technicians compared to school teachers: Impaired blood glucose (9.6% vs. 1.2%, pauto-technicians. Based on the WHO and the Harmonized criteria, metabolic syndrome was more frequent among auto-technicians compared to school teachers. (8.4% vs. 1.2% and 19.3% vs. 7.2% respectively, pauto technicians despite their high level of physical activity, exertion and education compared to teachers. This may be related to the increased occupational exposure to organic and inorganic materials from dust particles, oil and oil related matter and particulate matter among auto technicians. Prompt definitive evaluation of this concept and appropriate health education to encourage safety mechanism can reduce this burden of metabolic syndrome among auto technicians in Nigeria.

Blackwell, E; Nesbit, M; Petridis, H

2017-05-12

Statement of the problem Digital workflows (CAD/CAM) have been introduced in dentistry during recent years. No published information exists on dental technicians' use and reporting of this technology.Purpose The aim of this cross sectional survey was to identify the extent digital technology has infiltrated the workplace and to investigate the factors affecting the use of CAD-CAM technology by dental laboratory technicians within Ireland and the UK.Materials and methods A web-based questionnaire was composed (Opinio, Object Planet Inc. Oslo, Norway) and distributed to UK and Irish dental technicians. Answers to all questions were anonymous and grouped such that general information was gathered initially, followed by branching of the survey into two sections depending on whether or not the respondent worked with CAD-CAM technology. Results were compiled and statistical analysis (Fisher's Exact test, SPSS, IBM, Armonk, New York, USA) was performed in order to investigate any correlation between various demographic variables and the answers provided.Results The survey was distributed to 760 UK technicians and 77 Irish technicians. The total number of completed surveys was 105, which yielded a total response rate of 14%. Most technicians reported using some form of CAD/CAM aspect in the workflow, and this was more significant for technicians working in large laboratories. Most training received was company-led. Large laboratories were also significantly correlated with less outsourcing of CAD/CAM work and a change in dental material use leading to the increase of zirconia and the decrease of noble alloys. Dental technicians did not report any significant change in working relationships and staffing as a result of CAD/CAM incorporation. High initial investment cost was the most common reason quoted from non-users, along with the lack of such technology in their working environment.

Recovery Act: Training Program Development for Commercial Building Equipment Technicians

Energy Technology Data Exchange (ETDEWEB)

2012-07-12

The overall goal of this project has been to develop curricula, certification requirements, and accreditation standards for training on energy efficient practices and technologies for commercial building technicians. These training products will advance industry expertise towards net-zero energy commercial building goals and will result in a substantial reduction in energy use. The ultimate objective is to develop a workforce that can bring existing commercial buildings up to their energy performance potential and ensure that new commercial buildings do not fall below their expected optimal level of performance. Commercial building equipment technicians participating in this training program will learn how to best operate commercial buildings to ensure they reach their expected energy performance level. The training is a combination of classroom, online and on-site lessons. The Texas Engineering Extension Service (TEEX) developed curricula using subject matter and adult learning experts to ensure the training meets certification requirements and accreditation standards for training these technicians. The training targets a specific climate zone to meets the needs, specialized expertise, and perspectives of the commercial building equipment technicians in that zone. The combination of efficient operations and advanced design will improve the internal built environment of a commercial building by increasing comfort and safety, while reducing energy use and environmental impact. Properly trained technicians will ensure equipment operates at design specifications. A second impact is a more highly trained workforce that is better equipped to obtain employment. Organizations that contributed to the development of the training program include TEEX and the Texas Engineering Experiment Station (TEES) (both members of The Texas A&M University System). TEES is also a member of the Building Commissioning Association. This report includes a description of the project

Internet-based cognitive behavioural therapy (iCBT) for depression is effective when guided by a clinician, less so if unguided. Would guidance from a technician be as effective as guidance from a clinician? Randomized controlled non-inferiority trial comparing three groups: Clinician-assisted vs. technician-assisted vs. delayed treatment. Community-based volunteers applied to the VirtualClinic (www.virtualclinic.org.au) research program, and 141 participants with major depressive disorder were randomized. Participants in the clinician- and technician-assisted groups received access to an iCBT program for depression comprising 6 online lessons, weekly homework assignments, and weekly supportive contact over a treatment period of 8 weeks. Participants in the clinician-assisted group also received access to a moderated online discussion forum. The main outcome measures were the Beck Depression Inventory (BDI-II) and the Patient Health QUESTIONnaire-9 Item (PHQ-9). Completion rates were high, and at post-treatment, both treatment groups reduced scores on the BDI-II (ptechnician-assisted groups respectively, and on the PHQ-9, were 1.54 and 1.60 respectively. At 4-month follow-up participants in the technician group had made further improvements and had significantly lower scores on the PHQ-9 than those in the clinician group. A total of approximately 60 minutes of clinician or technician time was required per participant during the 8-week treatment program. Both clinician- and technician-assisted treatment resulted in large effect sizes and clinically significant improvements comparable to those associated with face-to-face treatment, while a delayed treatment control group did not improve. These results provide support for large scale trials to determine the clinical effectiveness and acceptability of technician-assisted iCBT programs for depression. This form of treatment has potential to increase the capacity of existing mental health services. Australian New

Pharmacy technicians are a vital part of the health care workforce. Little is known about perceptions of their own work environment that would engender more effective recruitment, retention, and management strategies by pharmacists and employers. The purpose of this study was to gain a greater understanding of certified pharmacy technician worklife. Specific objectives included the identification of themes of worklife phenomena to assist with the development of appropriate responses by other pharmacy stakeholders and to ascertain the contribution of various factors engendering or discouraging career commitment of pharmacy technicians. Semi-structured in-depth interviews were carried out with a convenience sample of pharmacy technicians in one U.S. state, who varied by their work settings and level of experience. The interview guide and corresponding participant responses were framed from around an organizational cultural basis rooted in organizational behavior theory. Notes from the interviews were analyzed thematically using directed content analysis. Four primary themes emerged, including: career impetus, job responsibilities, quality of work life, and equitable partnership. The data revealed pharmacy technicians' need for self-actualization and recognition of the value they bring to the organization. The participants identified primary responsibilities that contribute to their sense of worth and those that if not managed adequately potentially detract from their well-being and effectiveness. Findings in regard to rate of pay corroborate previous work on wages as both an intrinsic and extrinsic motivator. Pharmacy technicians seek equity among each other (their peers) and in a mutually beneficial relationship with their employing organization. This study provides the impetus for interventions and further study that should serve to enhance pharmacy technician effectiveness, quality of work life, and longevity in an emerging profession.

Full Text Available Objectives: The aim of this 7-year follow-up study was to determine respiratory changes in dental technicians. Material and Methods: In our region, in the year 2005, 36 dental technicians were evaluated with a cross-sectional study on respiratory occupational diseases, and in 2012 we evaluated them again. Inclusion of information on respiratory symptoms and demographic features questionnaires was applied. Pulmonary function tests (PFT were performed. Chest X-rays (CXR were evaluated according to the ILO-2000 classification. For the comparisons of the technicians' findings in 2005 and 2012, data analyses were performed with the Wilcoxon test in addition to descriptive statistical procedures. Results: In 2012, 19 out of the 36 technicians continued to work in the same place, so we were able to evaluate their findings. The prevalence of respiratory symptoms in dental technician was as follows: dyspnea 7 (37%, cough 6 (32%, and phlegm 5 (26%. According to ILO classifications in 2005, among the 36 technicians, 5 (13.8% had pneumoconiosis. At the end of 7 years, there were 9 pneumoconiosis cases among the 19 remaining technicians (47%. Thus, there was a statistically significant progression on the profusion of the radiologic findings (p < 0.005. Also there was a significant worsening on spirometric findings (p < 0.05. Conclusion: In dental technicians, a determination of both radiologic and functional progressions at the end of 7 years demonstrate that the primary and secondary preventive measures are necessary for these workplaces. Workplaces must be regularly controlled for worker health and hygiene.

This is a qualitative, exploratory and descriptive study whose general objective was to learn, considering the perspective of the nursing technician who works in school hospitals, the competencies developed during their educational process to implement the Nursing Care Systematization (NCS). Data collection and analysis were carried out through a focal group, with content analysis and nursing technicians. Two thematic categories emerged: The participation of the nursing technician in the NCS and The competencies in the education of the nursing technician. Each one received two subcategories: Conception of the NCS and (De)valuation of the NCS, Technical-scientific competency and Competency in the interpersonal relationship, respectively. It was observed that the NCS must be shared, discussed and made public among nursing professionals, so that they may acknowledge themselves as the leading actors of their methodology and be aware that their practices determine the results.

Full Text Available The aim of this study was to evaluate potential DNA damage and cytotoxicity in pathology laboratory technicians exposed to organic solvents, mainly xylene. Peripheral blood and buccal cells samples were collected from 18 technicians occupationally exposed to organic solvents and 11 non-exposed individuals. The technicians were sampled at two moments: Monday and Friday. DNA damage and cytotoxicity were evaluated using the Comet Assay and the Buccal Micronucleus Cytome assay. Fifteen subjects (83.5% of the exposed group to solvents complained about some symptom probably related to contact with vapours of organic solvents. DNA damage in the exposed group to solvents was nearly 2-fold higher on Friday than on Monday, and in both moments the individuals of this group showed higher levels of DNA damage in relation to controls. No statistical difference was detected in buccal cell micronucleus frequency between the laboratory technicians and the control group. However, in the analysis performed on Friday, technicians presented higher frequency (about 3-fold of karyolytic and apoptotic-like cells (karyorrhectic and pyknotic in relation to control group. Considering the damage frequency and the working time, a positive correlation was found in the exposed group to solvents (r=0.468; p=0.05. The results suggest that pathology laboratory workers inappropriately exposed to organic solvents have increased levels of DNA damage.

Full Text Available What significant changes are librarians and library technicians experiencing in their roles? A survey put forward across Canada to librarians and library technicians addressing this question was conducted in February 2014. Eight hundred eighty-two responses were obtained from librarians, defined as MLIS graduates, and library technicians, defined as graduates from a two-year library diploma program. Respondents needed to have been employed in the last two years in these roles and students of either an MLIS or LIT program were also welcome to participate. The results suggest that both librarians and library technicians perceive their roles as growing in scope and complexity and that the lines of responsibility are blurring. A majority of respondents indicated that they perceive a change in their roles in the past five years and commented on what the perceived changes were. Librarian and library technician roles may be shifting away from what may be viewed as traditional or clearly defined responsibilities and both librarians and library technicians may be taking on new tasks as well as experiencing task overlap. All library staff will need to be fluid, adaptable, and open to change. Library school curricula and workplace training need to incorporate the development of these competencies. Quels sont les changements importants éprouvés par les bibliothécaires et les bibliotechniciens dans leurs rôles? Un sondage mené en février de 2014 a posé cette question aux bibliothécaires et aux bibliotechniciens dans tout le Canada.

Traditionally, pharmacy technicians have worked alongside pharmacists in community and hospital pharmacy. Changes within pharmacy provide opportunity for role expansion and with no apparent career pathway, there is a need to define the current pharmacy technician role and role in medicines optimisation. To capture the current roles of pharmacy technicians and identify how their future role will contribute to medicines optimisation. Following ethical approval and piloting, an online survey to ascertain pharmacy technicians' views about their roles was undertaken. Recruitment took place in collaboration with the Association of Pharmacy Technicians UK. Data were exported to SPSS, data screened and descriptive statistics produced. Free text responses were analysed and tasks collated into categories reflecting the type of work involved in each task. Responses received were 393 (28%, n = 1380). Results were organised into five groups: i.e., hospital, community, primary care, General Practitioner (GP) practice and other (which included HM Prison Service). Thirty tasks were reported as commonly undertaken in three or more settings and 206 (84.7%, n = 243) pharmacy technicians reported they would like to expand their role. Tasks core to hospital and community pharmacy should be considered for inclusion to initial education standards to reflect current practice. Post qualification, pharmacy technicians indicate a significant desire to expand clinically and managerially allowing pharmacists more time in patient-facing/clinical roles.

Occupational lung diseases are caused by several toxic substances including heavy metals; however, the exact pathologic mechanisms remain unknown. In the workplace, dental technicians are often exposed to heavy metals such as cobalt, nickel, or beryllium and occasionally develop occupational lung diseases. We described a case of occupational lung disease in a patient who was employed as a dental technician for over a decade. A 31-year-old, non-smoking woman presented with productive cough and shortness of breath of several weeks duration. Chest computed tomography revealed a large number of scattered, bilateral small pulmonary nodules throughout the lung field, and multiple mediastinal lymph nodes enlargement. Percutaneous needle biopsy showed multifocal small granulomas with foreign body type giant cells suggestive of heavy metals inhalation. The patient's condition improved on simple avoidance strategy for several months. This case highlighted the importance of proper workplace safety.

2014-01-01

In the United States, approximately 236,000 people work in 37,600 auto collision-repair businesses. Workers in the collision-repair industry may be exposed to a wide range of physical and chemical hazards. This manuscript examines the relationship of safety climate as reported by collision repair shop workers and owners to: (1) an independent business safety assessment, and (2) employee self-reported work practices. The study was conducted in the Twin Cities metropolitan area. A total of 199 workers from 49 collision shops completed a survey of self-reported work practices and safety climate. Surveys were completed by an owner or manager in all but three shops. In general, self-reported work practices were poor. Workers' scores on safety climate were uniformly lower than those of owners. For workers, there was no correlation between how well the business scored on an independent audit of business safety practices and the safety climate measures they reported. For owners, however, there was a positive correlation between safety climate scores and the business safety assessment. For workers, safety rules and procedures were associated with improved work practices for those engaged in both painting-related and body technician-related activities. The enforcement of safety rules and procedures emerged as a strong factor positively affecting self-reported work practices. These findings identify a simple, cost effective path to reducing hazards in small workplaces. © 2013 Wiley Periodicals, Inc.

Tandon, Biranche; Blaker, Jonny J; Cartmell, Sarah H

2018-04-16

The process of bone repair and regeneration requires multiple physiological cues including biochemical, electrical and mechanical - that act together to ensure functional recovery. Myriad materials have been explored as bioactive scaffolds to deliver these cues locally to the damage site, amongst these piezoelectric materials have demonstrated significant potential for tissue engineering and regeneration, especially for bone repair. Piezoelectric materials have been widely explored for power generation and harvesting, structural health monitoring, and use in biomedical devices. They have the ability to deform with physiological movements and consequently deliver electrical stimulation to cells or damaged tissue without the need of an external power source. Bone itself is piezoelectric and the charges/potentials it generates in response to mechanical activity are capable of enhancing bone growth. Piezoelectric materials are capable of stimulating the physiological electrical microenvironment, and can play a vital role to stimulate regeneration and repair. This review gives an overview of the association of piezoelectric effect with bone repair, and focuses on state-of-the-art piezoelectric materials (polymers, ceramics and their composites), the fabrication routes to produce piezoelectric scaffolds, and their application in bone repair. Important characteristics of these materials from the perspective of bone tissue engineering are highlighted. Promising upcoming strategies and new piezoelectric materials for this application are presented. Electrical stimulation/electrical microenvironment are known effect the process of bone regeneration by altering the cellular response and are crucial in maintaining tissue functionality. Piezoelectric materials, owing to their capability of generating charges/potentials in response to mechanical deformations, have displayed great potential for fabricating smart stimulatory scaffolds for bone tissue engineering.

Tecuci, Gheorghe; Hieb, Michael R.; Dybala, Tomasz

1995-01-01

Over several years we have developed a multistrategy apprenticeship learning methodology for building knowledge-based systems. Recently we have developed and applied our methodology to building intelligent agents. This methodology allows a subject matter expert to build an agent in the same way in which the expert would teach a human apprentice. The expert will give the agent specific examples of problems and solutions, explanations of these solutions, or supervise the agent as it solves new problems. During such interactions, the agent learns general rules and concepts, continuously extending and improving its knowledge base. In this paper we present initial results on applying this methodology to build an intelligent adaptive agent for monitoring and repair of the electrical power system of an orbital satellite, stressing the interaction with the expert during apprenticeship learning.

The aim of this study was to identify the effects of long term exposure of X-ray on diagnostic technicians which they work at Kirkuk hospitals through examining some hematological parameters which are white blood cells (WBC), Neutrophils, Lymphocyte, Monocyte, Eosinophil, Basophil, Reactive Lymphocyte, red blood cells (RBC), hemoglobin (Hb), hematocrit (HCT), Mean Cell Volume (MCV), Mean Corpuscular Hemoglobin (MCH), Mean Cell Hemoglobin Concentration (MCHC), Red Cell Distribution Width (RDW), Platelet (PLT). The study included 54 male diagnostic technicians and 54 male healthy controls match with the first group to show any alteration of the hematological parameters. The diagnostic technicians divided into two groups depending on their work experience and hours working per day. The statistical analysis was performed using (Graph-pad) program. Our results showed that the Complete blood cells count (CBC) parameters (Neutrophil, Monocytes, Basophile, MCV, RDW and PLT) significantly (Pgroups of the diagnostic technicians compared with their controls. We concluded that chronic exposure of X-ray can significantly alter some hematological parameters and the number of hours working per day has observable effects on the some hematological parameters. We recommended training and courses about hazard of ionizing radiation should be organized for enhance the healthcare quality of the technicians and to improve their knowledge about benefit of radiation protection tools to protect themselves from any overexposure during the daily life.

Preparing technicians for engineering materials technology

A long held principle is that for every engineer and scientist there is a need for ten technicians to maximize the efficiency of the technology team for meeting needs of industry and government. Developing an adequate supply of technicians to meet the requirements of the materials related industry will be a challenge and difficult to accomplish. A variety of agencies feel the need and wish to support development of engineering materials technology programs. In a joint effort among Battelle Laboratories, the Department of Energy (DOE) and Northwest College and University Association for Science (NORCUS), the development of an engineering materials technology program for vocational programs and community colleges for the Pacific Northwest Region was recently completed. This effort has implications for a national model. The model Associate of Applied Science degree in Engineering Materials Technology shown provides a general structure. It purposely has course titles which need delimiting while also including a core of courses necessary to develop cognitive, affective and psychomotor skills with the underlining principles of math, science and technology so students have job entry skills, and so that students can learn about and adapt to evolving technology.

1987-05-01

The contemporary pharmacy practice manager faces the challenge of designing pharmacy service programs that not only satisfy the needs of the patient, but at the same time satisfy and motivate the pharmacists and technicians who sustain the programs. This research examined the team design, which has been recommended but not fully described in the literature. This application did not explore the full potential of the team design in the hospital pharmacy setting. More study is needed in this area to assess the impact of work group design on the expansion of clinical programs, employee turnover rates, quality and quantity of work produced, and, most important, the impact on job satisfaction enjoyed by pharmacists and technicians.

Two methods were used to collect blood from the jugular vein of dogs. In both techniques, only one technician was required. A rope with a slip knot was placed around the base of the neck to assist in restraint and act as a tourniquet for the vein. The technician used one hand to restrain the dog by the muzzle and position the head. The other hand was used for collecting the sample. One of the methods could be accomplished with the dog in its cage. The bleeding techniques were rapid, requiring approximately 1 minute per dog.

Background: Traditionally, pharmacy technicians have worked alongside pharmacists in community and hospital pharmacy. Changes within pharmacy provide opportunity for role expansion and with no apparent career pathway, there is a need to define the current pharmacy technician role and role in medicines optimisation. Aim: To capture the current roles of pharmacy technicians and identify how their future role will contribute to medicines optimisation. Methods: Following ethical approval and piloting, an online survey to ascertain pharmacy technicians’ views about their roles was undertaken. Recruitment took place in collaboration with the Association of Pharmacy Technicians UK. Data were exported to SPSS, data screened and descriptive statistics produced. Free text responses were analysed and tasks collated into categories reflecting the type of work involved in each task. Results: Responses received were 393 (28%, n = 1380). Results were organised into five groups: i.e., hospital, community, primary care, General Practitioner (GP) practice and other (which included HM Prison Service). Thirty tasks were reported as commonly undertaken in three or more settings and 206 (84.7%, n = 243) pharmacy technicians reported they would like to expand their role. Conclusions: Tasks core to hospital and community pharmacy should be considered for inclusion to initial education standards to reflect current practice. Post qualification, pharmacy technicians indicate a significant desire to expand clinically and managerially allowing pharmacists more time in patient-facing/clinical roles. PMID:28970452

Different perspectives on the role of mid-level workers in health care might represent a constraint to health policies. This study aimed to investigate how different agents view the participation of oral health technicians in direct activities of oral healthcare with the goal of understanding the related symbolic dispositions. Theoretical assumptions related to inter-professional collaboration and conflicts in the field of healthcare were used for this analysis. A researcher conducted 24 in-depth interviews with general dental practitioners, oral health technicians and local managers. The concepts of Pierre Bourdieu supported the data interpretation. The results indicated inter-professional relations marked by collaboration and conflict that reflect an action space related to different perspectives of primary care delivery. They also unveiled the symbolic devices related to the participation of oral health technicians that represent a constraint to the implementation of oral health policy, thus reducing the potential of primary health care in Brazil.

With massive retirements planned up to 2015, the French nuclear industry wishes to recruit technicians for the operation and maintenance of its power plants. The French nuclear park represents 19 power plants with 58 reactors. The nuclear industry personnel represents 19000 people at EdF and about 20000 people from about 600 different service provider companies. Technician's salary ranges from 1500 to 2800 euros for experienced people, bonus not included. Before being operational, the French nuclear technicians have to follow a long training period in one of the 20 specialized and certified training centres. However, the training demand is so important that the industry suffers from a lack of instructors as well. (J.S.)

Full Text Available Purpose. In difficult economic conditions, cost reduction of electricity consumption for the needs of production is an urgent task for the country’s industrial enterprises. Technical specifications of enterprises, which repair diesel locomotive hydraulic transmission, recommend conducting a certain amount of evaluation and regulatory tests to monitor their condition after repair. Experience shows that a significant portion of hydraulic transmission defects is revealed by bench tests. The advantages of bench tests include the ability to detect defects after repair, ease of maintenance of the hydraulic transmission and relatively low labour intensity for eliminating defects. The quality of these tests results in the transmission resource and its efficiency. Improvement of the technology of plant post-repairs hydraulic tests in order to reduce electricity consumption while testing. Methodology. The possible options for hydraulic transmission test bench improvement were analysed. There was proposed an energy efficiency method for diesel locomotive hydraulic transmission testing in locomotive repair plant environment. This is achieved by installing additional drive motor which receives power from the load generator. Findings. Based on the conducted analysis the necessity of improving the plant stand testing of hydraulic transmission was proved. The variants of the stand modernization were examined. The test stand modernization analysis was conducted. Originality. The possibility of using electric power load generator to power the stand electric drive motor or the additional drive motor was theoretically substantiated. Practical value. A variant of hydraulic transmission test stand based on the mutual load method was proposed. Using this method increases the hydraulic transmission load range and power consumption by stand remains unchanged. The additional drive motor will increase the speed of the input shaft that in its turn wil allow testing in

Facial nerve injury can cause severe long-term physical and psychological morbidity. There are limited repair options for an acutely transected facial nerve not amenable to primary neurorrhaphy. We hypothesize that a peptide amphiphile nanofiber neurograft may provide the nanostructure necessary to guide organized neural regeneration. Five experimental groups were compared, animals with 1) an intact nerve, 2) following resection of a nerve segment, and following resection and immediate repair with either a 3) autograft (using the resected nerve segment), 4) neurograft, or 5) empty conduit. The buccal branch of the rat facial nerve was directly stimulated with charge balanced biphasic electrical current pulses at different current amplitudes while nerve compound action potentials (nCAPs) and electromygraphic (EMG) responses were recorded. After 8 weeks, the proximal buccal branch was surgically re-exposed and electrically evoked nCAPs were recorded for groups 1-5. As expected, the intact nerves required significantly lower current amplitudes to evoke an nCAP than those repaired with the neurograft and autograft nerves. For other electrophysiologic parameters such as latency and maximum nCAP, there was no significant difference between the intact, autograft and neurograft groups. The resected group had variable responses to electrical stimulation, and the empty tube group was electrically silent. Immunohistochemical analysis and TEM confirmed myelinated neural regeneration. This study demonstrates that the neuroregenerative capability of peptide amphiphile nanofiber neurografts is similar to the current clinical gold standard method of repair and holds potential as an off-the-shelf solution for facial reanimation and potentially peripheral nerve repair.

Roeed, S.S.

1976-01-01

The workshop was held to exchange information on existing facilities and programmes in Asia and the Pacific for training nuclear laboratory technicians, to identify future training needs and to assess the need for IAEA's involvement in this field. As the participants outlined the requirements for nuclear laboratory technician training and the facilities available in their respective countries, it became evident that, in addition to the training of radioisotope laboratory technicians, they also wished to review the need for technician training for the operation of nuclear power plants and industrial application of atomic energy. The terms of reference of the workshop were extended accordingly. The opening address by Chang Suk Lee, the Korean Vice Minister of Science and Technology, noted the valuable contribution to quality control and other industrial uses that nuclear techniques have made in his country. He also reviewed the application of nuclear techniques in Korean agriculture and medicine. The participants explored various forms of co-operation that could be established between countries of the region. Exchange programmes, not only for students but also for expert teachers, and the exchange or loan of equipment were suggested. It was felt that some generalized training courses could be organized on a regional basis, and two countries advocated the setting up of a regional training centre. One suggestion was to arrange regional training courses in special fields that would move from one country to another. The need was felt for periodic regional meetings on training methods, course content and other questions relating to training of laboratory technicians. The IAEA was requested to act as a clearinghouse for information on available training facilities in the region and to advise on the curricula for technician training courses. The Agency was also asked to organize short courses for the training of instructors of technicians in the various fields of atomic

2014-01-01

Emergent care of the acute heart attack patient continues to be at the forefront of quality and cost reduction strategies throughout the healthcare industry. Although the average cardiac door-to-balloon (D2B) times have decreased substantially over the past few years, there are still vast disparities found in D2B times in populations that reside in rural areas. Such disparities are mostly related to prolonged travel time and subsequent delays in cardiac catherization lab team activation. Urban ambulance companies that are routinely staffed with paramedic level providers have been successful in the implementation of pre-hospital 12-lead electrocardiogram (ECG) protocols as a strategy to reduce D2B times. The authors sought to evaluate the evidence related to the risk and benefits associated with the replication of an ECG transmission protocol in a small rural emergency medical service. The latter is staffed with emergency medical technician-basics (EMT-B), emergency medical technician-advanced (EMT-A), and emergency medical technician-intermediate (EMT-I) level. The evidence reviewed was limited to studies with relevant data regarding the challenges and complexities of the ECG transmission process, the difficulties associated with ECG transmission in rural settings, and ECG transmission outcomes by provider level. The evidence supports additional research to further evaluate the feasibility of ECG transmission at the non-paramedic level. Multiple variables must be investigated including equipment cost, utilization, and rural transmission capabilities. Clearly, pre-hospital ECG transmission and early activation of the cardiac catheterization laboratory are critical components to successfully decreasing D2B times.

Promoting peripheral myelin repair.

Science.gov (United States)

Zhou, Ye; Notterpek, Lucia

2016-09-01

Compared to the central nervous system (CNS), peripheral nerves have a remarkable ability to regenerate and remyelinate. This regenerative capacity to a large extent is dependent on and supported by Schwann cells, the myelin-forming glial cells of the peripheral nervous system (PNS). In a variety of paradigms, Schwann cells are critical in the removal of the degenerated tissue, which is followed by remyelination of newly-regenerated axons. This unique plasticity of Schwann cells has been the target of myelin repair strategies in acute injuries and chronic diseases, such as hereditary demyelinating neuropathies. In one approach, the endogenous regenerative capacity of Schwann cells is enhanced through interventions such as exercise, electrical stimulation or pharmacological means. Alternatively, Schwann cells derived from healthy nerves, or engineered from different tissue sources have been transplanted into the PNS to support remyelination. These transplant approaches can then be further enhanced by exercise and/or electrical stimulation, as well as by the inclusion of biomaterial engineered to support glial cell viability and neurite extension. Advances in our basic understanding of peripheral nerve biology, as well as biomaterial engineering, will further improve the functional repair of myelinated peripheral nerves.

To implement a cost-effective low-dose computed tomography (LDCT) lung cancer screening program at the population level, accurate and efficient interpretation of a large volume of LDCT scans is needed. The objective of this study was to evaluate a workflow strategy to identify abnormal LDCT scans in which a technician assisted by computer vision (CV) software acts as a first reader with the aim to improve speed, consistency, and quality of scan interpretation. Without knowledge of the diagnosis, a technician reviewed 828 randomly batched scans (136 with lung cancers, 556 with benign nodules, and 136 without nodules) from the baseline Pan-Canadian Early Detection of Lung Cancer Study that had been annotated by the CV software CIRRUS Lung Screening (Diagnostic Image Analysis Group, Nijmegen, The Netherlands). The scans were classified as either normal (no nodules ≥1 mm or benign nodules) or abnormal (nodules or other abnormality). The results were compared with the diagnostic interpretation by Pan-Canadian Early Detection of Lung Cancer Study radiologists. The overall sensitivity and specificity of the technician in identifying an abnormal scan were 97.8% (95% confidence interval: 96.4-98.8) and 98.0% (95% confidence interval: 89.5-99.7), respectively. Of the 112 prevalent nodules that were found to be malignant in follow-up, 92.9% were correctly identified by the technician plus CV compared with 84.8% by the study radiologists. The average time taken by the technician to review a scan after CV processing was 208 ± 120 seconds. Prescreening CV software and a technician as first reader is a promising strategy for improving the consistency and quality of screening interpretation of LDCT scans.

The frequency of hypoxanthine phosphoribosyl transferase (HPRT) mutants among peripheral T-lymphocytes of radiotherapy technicians primarily exposed to 60Co was measured by the T-cell cloning method. Mutant frequencies of these technicians in 1984 and 1986 were significantly higher than those of physiotherapy technicians who worked in a neighboring service, and correlated significantly with thermoluminescence dosimeter readings recorded during the 6 mo preceding mutant frequency determination. Correlations decreased when related to dose recorded over longer time intervals. HPRT mutant frequency determination in peripheral lymphocytes is a good measure of recently received biologically effective radiation dose in an occupationally exposed population.

Emir, Faruk; Piskin, Bulent; Sipahi, Cumhur

2017-03-01

Studies that evaluated the effect of dental technician disparities on the accuracy of presectioned and postsectioned definitive casts are lacking. The purpose of this in vitro study was to evaluate the accuracy of presectioned and postsectioned definitive casts fabricated by different dental technicians by using a 3-dimensional computer-aided measurement method. An arch-shaped metal master model consisting of 5 abutments resembling prepared mandibular incisors, canines, and first molars and with a 6-degree total angle of convergence was designed and fabricated by computer-aided design and computer-aided manufacturing (CAD-CAM) technology. Complete arch impressions were made (N=110) from the master model, using polyvinyl siloxane (PVS) and delivered to 11 dental technicians. Each technician fabricated 10 definitive casts with dental stone, and the obtained casts were numbered. All casts were sectioned, and removable dies were obtained. The master model and the presectioned and postsectioned definitive casts were digitized with an extraoral scanner, and the virtual master model and virtual presectioned and postsectioned definitive casts were obtained. All definitive casts were compared with the master model by using computer-aided measurements, and the 3-dimensional accuracy of the definitive casts was determined with best fit alignment and represented in color-coded maps. Differences were analyzed using univariate analyses of variance, and the Tukey honest significant differences post hoc tests were used for multiple comparisons (α=.05). The accuracy of presectioned and postsectioned definitive casts was significantly affected by dental technician disparities (Ptechnician differences.

Studnek, Jonathan R

2016-12-01

The objective of this paper is to identify factors associated with compensation for Emergency Medical Technician (EMT)-Basics and Paramedics and assess whether these associations have changed over the period 1999-2008. Data obtained from the Longitudinal EMT Attributes and Demographic Study (LEADS) surveys, a mail survey of a random, stratified sample of nationally certified EMT-Basics and Paramedics, were analyzed. For the 1999-2003 period, analyses included all respondents providing Emergency Medical Services (EMS). With the addition of a survey in 2004 about volunteers, it was possible to exclude volunteers from these analyses. Over 60% of EMT-Basics reported being either compensated or noncompensated volunteers in the 2004-2008 period. This was substantially and significantly greater than the proportion of EMT-Paramedic volunteers (Technician (EMT)-Basics and Paramedics. Prehosp Disaster Med. 2016;31(Suppl. 1):s87-s95.

Combining BMI stimulation and mathematical modeling for acute stroke recovery and neural repair

Directory of Open Access Journals (Sweden)

Sara L Gonzalez Andino

2011-07-01

Full Text Available Rehabilitation is a neural plasticity-exploiting approach that forces undamaged neural circuits to undertake the functionality of other circuits damaged by stroke. It aims to partial restoration of the neural functions by circuit remodeling rather than by the regeneration of damaged circuits. The core hypothesis of the present paper is that - in stroke - Brain Machine Interfaces can be designed to target neural repair instead of rehabilitation. To support this hypothesis we first review existing evidence on the role of endogenous or externally applied electric fields on all processes involved in CNS repair. We then describe our own results to illustrate the neuroprotective and neuroregenerative effects of BMI- electrical stimulation on sensory deprivation-related degenerative processes of the CNS. Finally, we discuss three of the crucial issues involved in the design of neural repair-oriented BMIs: when to stimulate, where to stimulate and - the particularly important but unsolved issue of - how to stimulate. We argue that optimal parameters for the electrical stimulation can be determined from studying and modeling the dynamics of the electric fields that naturally emerge at the central and peripheral nervous system during spontaneous healing in both, experimental animals and human patients. We conclude that a closed-loop BMI that defines the optimal stimulation parameters from a priori developed experimental models of the dynamics of spontaneous repair and the on-line monitoring of neural activity might place BMIs as an alternative or complement to stem-cell transplantation or pharmacological approaches, intensively pursued nowadays.

Science.gov (United States)

El-Helaly, Mohamed; Balkhy, Hanan H; Vallenius, Laura

2017-11-25

Work-related carpal tunnel syndrome (CTS) has been reported in different occupations, including laboratory technicians, so this study was carried out to determine the prevalence and the associated personal and ergonomic factors for CTS among laboratory technicians. A cross-sectional study was conducted among 279 laboratory technicians at King Fahd Hospital, Saudi Arabia, who filled in a self-administered questionnaire, including questions regarding their demographic criteria, occupational history, job tasks, workplace tools, ergonomic factors at work, and symptoms suggestive of CTS. Physical examinations and electrodiagnostic studies were carried out for those who had symptoms suggestive of CTS to confirm the diagnosis. Univariate and multivariate analysis were performed for both personal and physical factors in association with confirmed CTS among laboratory technicians. The prevalence of CTS among the laboratory technicians was 9.7% (27/279). The following were the statistically significant risk factors for CTS among them: gender (all cases of CTS were female, P=0.00), arm/hand exertion (OR: 7.96; 95% CI: 1.84-34.33), pipetting (OR: 7.27; 95% CI: 3.15-16.78), repetitive tasks (OR: 4.60; 95% CI: 1.39-15.70), using unadjustable chairs or desks (OR: 3.35; 95% CI: 1.23-9.15), and working with a biosafety cabinet (OR: 2.49; 95% CI: 1.11-5.59). CTS cases had significant longer work duration (17.9 ± 5.6 years) than CTS non-case (11.5 ± 7.4 yeas) with low OR (1.108). This study demonstrates some personal and ergonomic factors associated with CTS among the laboratory technicians, including female gender, arm/hand exertion, pipetting, repetitive tasks, working with a biosafety cabinet, and an unadjusted workstation.

Nuclear instrument technician training

International Nuclear Information System (INIS)

Wollesen, E.S.

1991-01-01

This paper reports on Nuclear Instrument Technician (NIT) training that has developed at an accelerated rate over the past three decades. During the 1960's commercial nuclear power plants were in their infancy. For that reason, there is little wonder that NIT training had little structure and little creditability. NIT training, in many early plants, was little more than On-The Job Training (OJT). The seventies brought changes in Instrumentation and Controls as well as emphasis on the requirements for more in depth training and documentation. As in the seventies, the eighties saw not only changes in technologies but tighter requirements, standardized training and the development of accredited Nuclear Instrument Training; thus the conclusion: Nuclear Instrument Training Isn't What It Used To Be

Discount factor in planning decision of electric sector

International Nuclear Information System (INIS)

Becker, J.L.; Maurer, L.T.A.

1990-01-01

Researchers and technicians have been giving a lot of attention to the issue of discount factor in planning in the electric sector. In this paper we review the most important points under consideration, attempting to broaden the discussion and stimulate the creativity of the technicians involved with the sector. There appears to be an emerging consensus that the discount factor to be used must consider the capital costs associated with the main financial sources utilized. The traditional factor of 10% per year must be re-evaluated and augmented, in order to best reflect long range economical and financial conditions. The paper emphasizes the importance of the discount factor to several decisions made within the sector, including energy conservation. Because of the relevance of the topic to Brazil future, we strongly suggest the utilization of sensitivity analysis techniques. (author)

Guidelines for training and qualification of radiological protection technicians

International Nuclear Information System (INIS)

1987-08-01

These guidelines, used in combination with plant-specific job analysis, provide the framework for a training and qualification program for radiological protection technicians at nuclear power plants. Radiological protection technicians are defined as those individuals, both plant and contractor, who will be engaged in the evaluation of radiological conditions in the nuclear plant and the implementation of the necessary radiological safety measures as they apply to nuclear plant workers and members of the general public. An important aspect of this work is recognizing and handling unusual situations involving radioactivity, including incidents related to degraded core conditions. These guidelines incorporate the results of an industry-wide job analysis and task analysis (JTA) combined with industry operating experience review. However, the industry-wide analyses did not identify all important academic and fundamental knowledge and skills. Further in-depth analysis by subject matter experts produced additional knowledge and skills that were added to these guidelines. All utilities should use these guidelines in conjunction with plant-specific and industry-wide JTA results to develop or validate their radiological protection technician training program. Plant-specific information should be used to establish appropriate training program content. This plant-specific information should reflect unique job duties, equipment, operating experience, and trainee entry-level qualifications. Revisions to these guidelines should be reviewed for applicability and incorporated into the training program using each utility's training system development (TSD) procedures. Plant-specific job analysis and task analysis data is essential to the development of performance-based training programs. These analyses are particularly useful in selecting tasks for training and in developing on-the-job training (OJT), laboratory training, and mock-up training. Qualification programs based on these

2016-09-01

Lower back pain (LBP) is the most common complaint worldwide and the leading cause of disability in the workplace. In Colombia there are no epidemiological data on low back pain in aviation. This study aimed to characterize lower back pain in pilots and maintenance technicians in a Colombian commercial airline. Information was collected from the total population in a Colombian commercial airline in Bogota during the period from 2011 to 2013 using a voluntary survey which requested demographics, occupational (LEST survey) factors, back pain, and chronic pain (chronic pain grade scale). The prevalence rate of LBP in pilot respondents was 71% and the factors associated previously have belonged to the military forces: occupational exposure to physical load and work time. Chronic low back pain was at a prevalence of 49%. The prevalence of LBP in maintenance technicians was 65%. Associated factors were again similar to military forces and included mental workload. Chronic pain had a prevalence of 65%. Factors associated with chronic low back pain were the technicians' time in office and physical load. The prevalence of lower back pain in pilots is similar to that presented in the airline world population. In the case of maintenance technicians, the prevalence was higher than those found in other similar groups, but very similar to prevalences presented in different business industries, including the transport sector.

Results of a survey assessing trends and innovations in the use of pharmacy technicians and other nonpharmacist staff in the research pharmacy setting are reported. A Web-based survey was distributed to Internet communities of members of the American Society of Health-System Pharmacists and the University Health-System Consortium involved in investigational drug research and related practice areas. The survey collected data on the characteristics of institutions with pharmacy department staff dedicated to such research activities and the participation of pharmacists, technicians, and other staff in key areas of research pharmacy operations. Survey responses from 51 institutions were included in the data analysis. Overall, the reported distribution of assigned responsibility for most evaluated research pharmacy tasks reflected traditional divisions of pharmacist and technician duties, with technicians performing tasks subject to a pharmacist check or pharmacists completing tasks alone. However, some institutions reported allowing technicians to perform a number of key tasks without direct pharmacist supervision, primarily in the areas of inventory management and sponsor monitoring and auditing; almost half of the surveyed institutions reported technician involvement in teaching activities. In general, the reported use of "tech-check-tech" arrangements in research pharmacies was very limited. Some responding institutions reported the innovative use of nonpharmacist staff (e.g., paid interns, students and residents on rotation). Although the majority of research pharmacy tasks related to direct patient care are performed by or under the direct supervision of pharmacists, a variety of other essential tasks are typically assigned to pharmacy technicians and other nonpharmacist staff.

Development of a Training Program for Commercial Building Technicians

Energy Technology Data Exchange (ETDEWEB)

Rinholm, Rod

2013-05-31

This project focused on developing and deploying a comprehensive program of 22 training modules, including certification requirements, and accreditation standards for commercial building technicians, to help achieve the full savings potential of energy efficient buildings, equipment, and systems. This curriculum extended the currently available commercial building technician programs -- training a labor force in a growing market area focused on energy efficiency. The program helps to remove a major market impediment to low energy/zero energy commercial building system acceptance, namely a lack of operating personnel capable of handling more complex high efficiency systems. The project developed a training curriculum for commercial building technicians, with particular focus on high-efficiency building technology, and systems. In Phase 1, the project team worked collaboratively in developing a draft training syllabus to address project objectives. The team identified energy efficiency knowledge gaps in existing programs and plans and plans to address the gaps with either modified or new curricula. In Phase 2, appropriate training materials were developed to meet project objectives. This material was developed for alternative modes of delivery, including classroom lecture materials, e-learning elements, video segments, exercises, and hands-on training elements. A Certification and Accreditation Plan and a Commercialization and Sustainability Plan were also investigated and developed. The Project Management Plan was updated quarterly and provided direction on the management approaches used to accomplish the expected project objectives. GTI project management practices tightly coordinate project activities using management controls to deliver optimal customer value. The project management practices include clear scope definition, schedule/budget tracking, risk/issue resolution and team coordination.

2017-07-01

The results of the 2015 National Certified Pharmacy Technician Workforce Survey are described. A survey was e-mailed to a randomized sample of 5,000 certified pharmacy technicians (CPhTs) throughout the United States, with response reminders employed. Survey items eliciting demographic and work characteristics and work life attitudes were generated from the literature and qualitative interviews. This study aimed to describe job satisfaction, sources of stress, profession and employer commitment, education and training, and reasons for entry into the profession among CPhTs and determine relationships between those variables and CPhTs' level of involvement in various work activities, with particular attention paid to differences in practice setting. Frequency statistics, correlation analysis, and means testing were used to meet study objectives and identify significant differences. A total of 516 CPhTs currently working as a pharmacy technician responded to the survey. The CPhTs reported high levels of involvement in more traditional activities but less involvement in those that involve greater cognitive load. Respondents reported moderate levels of job satisfaction and commitment and somewhat high levels of stress overall. Most CPhTs chose to be a pharmacy technician because they desired to enter a healthcare field and help people and were recruited. CPhTs derived benefit from all aspects of education and training evaluated and most from on-the-job training. Perceived value of education and training was associated with higher satisfaction and commitment and with lower stress. There were a number of differences in these work life attitudes across practice settings and by involvement in various job functions. The results of the survey indicated that job satisfaction and commitment were moderate and that stress levels were somewhat high among CPhTs. There were a number of differences in work life attitudes across practice settings and by involvement in various job

2002-01-01

The purpose of this study was to evaluate the clinical and cytological changes in the ocular surface of radiology technicians (radiographers) exposed to diagnostic doses of radiation. The Schirmer, Rose Bengal staining and Tear-Break-Up-Time tear function tests were carried out following routine ophthalmic examination in 15 radiology technicians (group I) and 15 controls (group II). Impression cytology was performed by placing 5-mm-thick half-circular cellulose acetate filter paper in the upper and lower quadrants around the limbus. The cytological evaluation was made using the mapping technique. Significantly increased dry eye was detected in group I. In the impression cytology investigation, squamous metaplasia and intraepithelial lymphocytic infiltration was noted in all the group-I cases. A distinct change was observed between the regions showing squamous metaplasia and neigbouring normal epithelial cell structure. Dry eye and ocular surface cytological changes were observed in diagnostic radiology technicians. Routine ophthalmic evaluation of radiology technicians would be beneficial in detecting early cytological changes and dry eye. (orig.)

2017-06-01

PurposeThe purpose of this study is to describe the outcomes of a technician-delivered glaucoma referral triaging service with 'virtual review' of resultant data by a consultant ophthalmologist.Patients and methodsThe Glaucoma Screening Clinic reviewed new optometrist or GP-initiated glaucoma suspect referrals into a specialist ophthalmic hospital. Patients underwent testing by three ophthalmic technicians in a dedicated clinical facility. Data were reviewed at a different time and date by a consultant glaucoma ophthalmologist. Approximately 10% of discharged patients were reviewed in a face-to-face consultant-led clinic to examine the false-negative rate of the service.ResultsBetween 1 March 2014 and 31 March 2016, 1380 patients were seen in the clinic. The number of patients discharged following consultant virtual review was 855 (62%). The positive predictive value of onward referrals was 84%. Three of the 82 patients brought back for face-to-face review were deemed to require treatment, equating to negative predictive value of 96%.ConclusionsOur technician-delivered glaucoma referral triaging clinic incorporates consultant 'virtual review' to provide a service model that significantly reduces the number of onward referrals into the glaucoma outpatient department. This model may be an alternative to departments where there are difficulties in implementing optometrist-led community-based referral refinement schemes.

Internet-based cognitive behavioural therapy (iCBT) for generalized anxiety disorder (GAD) has been shown to be effective when guided by a clinician. The present study sought to replicate this finding, and determine whether support from a technician is as effective as guidance from a clinician. Randomized controlled non-inferiority trial comparing three groups: Clinician-assisted vs. technician-assisted vs. delayed treatment. Community-based volunteers applied to the VirtualClinic (www.virtualclinic.org.au) research program and 150 participants with GAD were randomized. Participants in the clinician- and technician-assisted groups received access to an iCBT program for GAD comprising six online lessons, weekly homework assignments, and weekly supportive contact over a treatment period of 10 weeks. Participants in the clinician-assisted group also received access to a moderated online discussion forum. The main outcome measures were the Penn State Worry Questionnaire (PSWQ) and the Generalized Anxiety Disorder-7 Item (GAD-7). Completion rates were high, and both treatment groups reduced scores on the PSWQ (ptechnician-assisted groups, respectively, and on the GAD-7 were 1.55 and 1.73, respectively. At 3 month follow-up participants in both treatment groups had sustained the gains made at post-treatment. Participants in the clinician-assisted group had made further gains on the PSWQ. Approximately 81 minutes of clinician time and 75 minutes of technician time were required per participant during the 10 week treatment program. Both clinician- and technician-assisted treatment resulted in large effect sizes and clinically significant improvements comparable to those associated with face-to-face treatment, while a delayed treatment/control group did not improve. These results provide support for large scale trials to determine the clinical effectiveness and acceptability of technician-assisted iCBT programs for GAD. This form of treatment has potential to increase the

There is paucity of data on the inter-observer agreement and diagnostic accuracy between a primary-care technician (vision technician) and an ophthalmologist. Hence, the current study was conducted to assess the accuracy of vision technicians, to screen potentially sight-threatening ocular conditions at rural vision centres of southern India and their agreement with an ophthalmologist. In July to August 2010, patients presenting to seven vision centres in Adilabad district (Andhra Pradesh) were selected and screened in a masked manner by seven vision technicians followed by an examination by a consultant ophthalmologist. Agreement was assessed between vision technicians and the ophthalmologist for screening of potential sight-threatening ocular conditions and decisions for referral. The ophthalmologist's findings were considered as the reference standard. Two hundred and seventy-nine patients were enrolled at seven vision centres with a mean age of 32.9 ± 21.8 years. Agreement for screening of ocular pathology was 0.82 (95 per cent CI, 0.8-0.83). There was excellent agreement for cataract (0.97; 95 per cent CI, 0.93-1), refractive error (0.98; 95 per cent CI, 0.96-1), corneal pathology (1.0; 95 per cent CI, 1.0-1.0) and other anterior segment pathology (0.95; 95 per cent CI, 0.9-1); the agreement was moderate to fair for detection of glaucoma suspects (0.43; 95 per cent CI, 0.28-0.60) and retinal pathology (0.39; 95 per cent CI, 0.14-0.63). Sensitivity for screening of anterior segment pathology was 94.6-100 per cent. There was a fair to moderate sensitivity for glaucoma suspect; 35.6 per cent (95 per cent CI, 21.9-51.2) and retinal pathology 26.3 per cent (95 per cent CI, 9.2-51.2). Specificity for screening of ocular pathology was 98.2 to 100 per cent. The kappa (κ) agreement for referral for any pathology was 0.82 (0.8-0.83) CONCLUSION: As there is good agreement between the vision technicians and the ophthalmologist for screening and referral of

Effective communication and cooperation between dentists and dental technicians are essential in providing quality services. There has been a lack of information regarding dentist-dental technician communications and current methods and materials used for the fabrication of fixed partial dentures (FPDs). This cross-sectional study identified the materials and techniques used for fabrication of FPDs, as well as the status of communication between dentists and dental technicians in Thessaloniki, Greece. A questionnaire was developed with 7 sections pertaining to procedures and materials used for the fabrication of fixed prostheses: general questions, infection control, impressions/interocclusal records, die technique/mounting, information from final casts, prostheses design/materials, and communication/shade selection. The questionnaire was anonymous and distributed by the Association of Dental Technicians of Thessaloniki to all member laboratories (228) in the wider province of Thessaloniki, Greece. Due to the absence of normal distribution of the results, frequencies and medians were reported. Ninety-six of 228 dental laboratories responded (42.1% response rate). Twenty-six percent of dental laboratories did not routinely disinfect incoming items. The dental technicians considered 30% of incoming final impressions and 20% of interocclusal registrations as inadequate. Half of the time (55%) final casts were mounted by technicians on simple hinge articulators. Only 20% of tooth preparations had adequate finish lines. The majority (70%) of fixed restorations were metal-ceramic. Fifty-seven percent of dental technicians considered the delivery time requested by dentists as insufficient. The information provided in this study indicates areas of weakness in communication between dentists and dental technicians, along with areas where both parties should use greater care during clinical and laboratory procedures.

There is a poor association between the dentist's evaluation of denture quality and patients' satisfaction with their dentures. Possible differences between dental professionals and patients' expectations might help explain differences in outcome evaluations. This study compared scores given by a dentist, a dental technician and patients for their expectations before and their final evaluation after complete dentures treatment. Twenty completely edentulous patients, a prosthodontist and a dental technician provided scores for the expected aesthetic and functional results of their dentures based on a visual analogue scale at baseline. Post-treatment completion ratings were given after adjustments, by dentist and patients. The dental technician provided post-treatment completion ratings after completing the dentures. The patients had higher expectations than the dental technician and the dentist perceived for both aesthetic and function (P < 0.001). The patients also presented higher post-treatment completion ratings than the dental professionals perceived for final aesthetics (P = 0.016, Kendall's W = 0.207) and function (P = 0.002, Kendall's W = 0.303). Only the dentist presented a statistically significant difference between expectations (lower) and final (higher) outcomes for aesthetics (P = 0.017) and function (P = 0.003). There was no correlation between expectations and post-treatment completion ratings according to the patients' age. There was also no correlation between the patients' gender and expectation scores. Patients presented higher expectations regarding their dentures than dental professionals. The dentist believed that dentures would bring fewer benefits than patients did, but his perception of denture benefits post-treatment was significantly higher than his expectations.

The procedure for repair welding of cracked steam turbine blades made of martensitic stainless steels has been developed using the gas tungsten arc welding process. Weld repair procedures were developed using both ER316L austenitic stainless steel filler wire and ER410 martensitic stainless steel filler wire. The repair welding procedure with austenitic filler wire was developed to avoid preheating of the blade as also hydrogen induced cold cracking, and involved evaluation of three different austenitic filler wires, viz. ER309L, ER316L and ERNiCr-3. The overall development of the repair welding procedure included selection of welding consumables (for austenitic filler metal), optimisation of post weld heat treatment parameters, selection of suitable method for local pre-heating and post-weld heat treatment (PWHT) of the blades, determination of mechanical properties of weldments in as-welded and PWHT conditions, and microstructural examination. After various trials using different procedures, the procedure of local PWHT using electrical resistance heating on the top surface of the weldment and monitoring the temperature by placing a thermocouple at the bottom of the weld, was found to give the most satisfactory results. A similar procedure was used for preheating while using ER410 filler metal. Mechanical testing of weldments before and after PWHT involved tensile tests at room temperature, face and root bend tests, and microhardness measurements across the fusion line and heat affected zone. During procedure qualification, mock-ups and actual repair welding, dye penetrant testing was used at different stages and where ever possible radiography was carried out. These procedures were developed for repair welding of cracked blades in the low-pressure (LP) steam turbines of Indian nuclear power plants. The procedure with ER316 L filler wire has so far been applied for repair welding of 2 cracked blades (made of AISI 410 SS) of LP steam turbines, while the procedure

Mini Review: Biomaterials for Enhancing Neuronal Repair

As they differentiate from neuroblasts, nascent neurons become highly polarized and elongate. Neurons extend and elaborate fine and fragile cellular extensions that form circuits enabling long-distance communication and signal integration within the body. While other organ systems are developing, projections of differentiating neurons find paths to distant targets. Subsequent post-developmental neuronal damage is catastrophic because the cues for reinnervation are no longer active. Advances in biomaterials are enabling fabrication of micro-environments that encourage neuronal regrowth and restoration of function by recreating these developmental cues. This mini-review considers new materials that employ topographical, chemical, electrical, and/or mechanical cues for use in neuronal repair. Manipulating and integrating these elements in different combinations will generate new technologies to enhance neural repair.

Williamson, Ray

2004-01-01

In the modern optical shop, technicians are typically skilled machine operators who work on only one phase of the manufacture for each and every component. The product is designed, specified, methodized, scheduled and integrated by people off the shop floor. Even at the component level, the people inside the shop usually see only one stage of completion. In an effort to make the relevance of their work visible; to demonstrate competence to their peers; to gain appreciation for the work of others; and to give them a meaningful connection with the functions of optical systems, I created "The Telescope Project" for my former employer. I invited those interested to participate in an after-hours, partially subsidized project to build telescopes for themselves. The ground-rules included that we would all make the same design (thus practicing consensus and configuration management); that we would all work on every phase (thus learning from each other); and that we would obtain our parts by random lot at the end (thus making quality assurance a personal issue). In the process the participating technicians learned about optical theory, design, tolerancing, negotiation, scheduling, purchasing, fabrication, coating and assembly. They developed an appreciation for each other's contributions and a broader perspective on the consequences of their actions. In the end, each obtained a high-quality telescope for his or her personal use. Several developed an abiding love for astronomy. The project generated much interest from technicians who didn"t initially choose to participate. In this paper I describe the project in detail.

Full Text Available The aim of the current investigation is to analyze the dental-technicians’ awareness of the soft relining materials, their characteristics, advantages, shortcomings and methods for relining. Materials and methods: For the purpose of this investigation a standard questionnaire has been presented. A direct survey method, documentary and statistical method, as well as graphical methods, including tables, charts, graphics and figures, were used. Data were analysed with the help of IBM SPSS Statistics (ver. 19. Results: One hundred and eight dental technicians were included in the survey, evenly distributed by gender. Removable and fixed prosthodontics is the most commonly mentioned spheres of dental activities. Almost all included in the investigation point out the laboratory relining method as the most frequently used. Acrylic and silicone SRM are the most used groups of relining materials. Change of colour and hardness are the most frequently noticed shortcomings of these materials. The majority of the dental technicians declare that they have never done replacement of SRM or the relining has lasted more than a year. Discussion: The correlation between the age and the years of labour service among the participants is quite obvious. Most of them start working soon after their graduation. Removable prosthodontics is among the priorities for the majority of the labs. Conclusion: Although their unambiguous advantages, the soft relining materials have lots of shortcomings as well. The major problems are connected with their change of colour and hardness. Nevertheless, the dental technicians find them useful and reliable in overcoming specific prosthetic problems.

It is difficult to acquire a chest X-ray of a crying infant at maximum inspiration. A computer program was developed for technician training. Method. Video clips of 3 babies were used and the moment of deepest inspiration was determined in the single-frame view. 12 technicians simulated chest radiographs at normal video speed by pushing a button. The computer program stopped the video and calculated the period of time to the optimal instant for a chest X-ray. Demonstration software can be tested at website online. Every technician simulated 10 chest X-rays for each of the 3 video clips. The technicians then spent 40 minutes practicing performing chest X-rays at optimal inspiration. The test was repeated after 5, 20, and 40 minutes of practice. Results. 6 participants showed a significant improvement after exercises (collective 1). Deviation from the optimal instant for taking an X-ray at inspiration decreased from 0.39 to 0.22 s after 40 min of practice. 6 technicians showed no significant improvement (collective 2). Deviation decreased from a low starting value of 0.25 s to 0.21 s. Conclusion. The tested computer program improves the ability of radiology technicians to take a chest X-ray at optimal inspiration in a crying child

Tomotherapy is a technique of IMRT and IGRT using a linear accelerator and a helical CT-scanner. To reach this targeting of precision, the repositioning of the patient is essential. The use of a contention adapted according to the location of the disease and the morphology of the patient is necessary for the safety of this one and the treatment. Once the patient positioned on the reference table, technicians of imager's team check by the acquisition of helical imagery with the reference CT-scanner the position of the patient, the zone of the PTV and healthy organs in the protected surroundings. At first, adjustment will be made automatically on three planes of the space (axial, sagittal, frontal) and three rotations (pitch, roll and yaw) by the device of treatment, then the technicians of imagery will bring a modification of these recalls manually. After validation, the processing will then be made in complete safety for the patient and the nursing. This check by MVCT is daily before every session of processing. It is made by the technicians of imagery. The radiation oncologist confirms the images at j0, then controls once a week MVCT. Traceability in the file of the patient of the various marks (osseous and\\or soft tissue) necessary for the daily gaps will be noted by this one to delegate to the technicians of imagery the validation of the MVCT before every session.

In May 2012, the New Hampshire (NH) Division of Public Health Services (DPHS) was notified of 4 persons with newly diagnosed hepatitis C virus (HCV) infection at hospital X. Initial investigation suggested a common link to the hospital cardiac catheterization laboratory (CCL) because the infected persons included 3 CCL patients and a CCL technician. NH DPHS initiated an investigation to determine the source and control the outbreak. NH DPHS conducted site visits, case patient and employee interviews, medical record and medication use review, and employee and patient HCV testing using enzyme immunoassay for anti-HCV, reverse-transcription polymerase chain reaction for HCV RNA, nonstructural 5B (NS5B) and hypervariable region 1 (HVR1) sequencing, and quasispecies analysis. HCV HVR1 analysis of the first 4 cases confirmed a common source of infection. HCV testing identified 32 of 1074 CCL patients infected with the outbreak strain, including 3 patients coinfected with >1 HCV strain. The epidemiologic investigation revealed evidence of drug diversion by the HCV-infected technician, evidenced by gaps in controlled medication control, higher fentanyl use during procedures for confirmed cases, and building card key access records documenting the presence of the technician during days when transmission occurred. The employee's status as a traveling technician led to a multistate investigation, which identified additional cases at prior employment sites. This is the largest laboratory-confirmed drug diversion-associated HCV outbreak published to date. Recommendations to reduce drug diversion risk and to conduct outbreak investigations are provided.

Requirements for, and training and certification of, quality assurance technicians for nuclear power plants

The paper examines the requirements for, and training and certification of, technicians working in a quality assurance department at periods when the site, the main supplier and the engineering firm are being selected for construction, commissioning and operation of a light-water nuclear power plant with an output of approximately 1000 MW(e). In determining the system to be applied for the present work, account is taken of the special fields of engineering, supply, commissioning and operation. To this end, an analysis is made of the necessary organization, pointing out the number of technicians in each of the phases mentioned, and the necessary experience and knowledge required for discharging the functions indicated and for obtaining the appropriate certification. The second generation of Spanish nuclear power stations - about 7500MW(e) - demonstrated the need for quality assurance technicians. The Spanish Atomic Forum, a member of Foratom, is the first Spanish body to deal with the problem of training of such technicians at the national level through holding of seminars. This led to the appearance (in April 1974) of the first publication in Spanish on these techniques, a document which is still being used for teaching purposes. Later, it was the university and the professional associations which, with the support of the State Administration, undertook to provide this instruction. The paper also analyses Spanish experience in the teaching of quality assurance techniques during the period 1975-80, describing the programmes and contents of the courses

Dynamic impact of brief electrical nerve stimulation on the neural immune axis-polarization of macrophages toward a pro-repair phenotype in demyelinated peripheral nerve.

Science.gov (United States)

McLean, Nikki A; Verge, Valerie M K

2016-09-01

Demyelinating peripheral nerves are infiltrated by cells of the monocyte lineage, including macrophages, which are highly plastic, existing on a continuum from pro-inflammatory M1 to pro-repair M2 phenotypic states. Whether one can therapeutically manipulate demyelinated peripheral nerves to promote a pro-repair M2 phenotype remains to be elucidated. We previously identified brief electrical nerve stimulation (ES) as therapeutically beneficial for remyelination, benefits which include accelerated clearance of macrophages, making us theorize that ES alters the local immune response. Thus, the impact of ES on the immune microenvironment in the zone of demyelination was examined. Adult male rat tibial nerves were focally demyelinated via 1% lysophosphatidyl choline (LPC) injection. Five days later, half underwent 1 hour 20 Hz sciatic nerve ES proximal to the LPC injection site. ES had a remarkable and significant impact, shifting the macrophage phenotype from predominantly pro-inflammatory/M1 toward a predominantly pro-repair/M2 one, as evidenced by an increased incidence of expression of M2-associated phenotypic markers in identified macrophages and a decrease in M1-associated marker expression. This was discernible at 3 days post-ES (8 days post-LPC) and continued at the 5 day post-ES (10 days post-LPC) time point examined. ES also affected chemokine (C-C motif) ligand 2 (CCL2; aka MCP-1) expression in a manner that correlated with increases and decreases in macrophage numbers observed in the demyelination zone. The data establish that briefly increasing neuronal activity favorably alters the immune microenvironment in demyelinated nerve, rapidly polarizing macrophages toward a pro-repair phenotype, a beneficial therapeutic concept that may extend to other pathologies.

It is not fully understood where and how people are exposed to sensitizing metals. Much can be learnt from studying occupational settings where metals are handled. To quantify cobalt (Co), chromium (Cr) and nickel (Ni) exposure on the skin and in the air, and urine levels, in dental technicians working with tools and alloys that may result in skin and respiratory exposure. The metal skin dose was quantified with acid wipe sampling in dental technicians (n = 13). Air exposure was monitored by personal air sampling. Spot urine samples were collected for 24 h. Metals were analysed with inductively coupled plasma mass spectrometry. Before work, Co was detected on the skin of 10 participants (0.00025-0.0039 µg/cm 2 ), and Cr (0.00051-0.011 µg/cm 2 ) and Ni (0.0062-0.15 µg/cm 2 ) on the skin of all participants. After a 2-h period without hand washing, CoCr-exposed participants had more Co on the skin (p = 0.004) than non-CoCr-exposed participants. Co was found in 10 air samples (0.22-155 µg/m 3 ), Cr in nine (0.43-71 µg/m 3 ), and Ni in four (0.48-3.7 µg/m 3 ). Metal urine concentrations were considered to be normal. Dental technicians were exposed to Co, Cr and Ni on the skin and through the air, which was not reflected in the urine concentrations in this study. Cobalt skin doses may potentially elicit allergic contact dermatitis and cause sensitization. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Objective To explore community pharmacy technician workflow change after implementation of an automated robotic prescription-filling device. Methods At an independent community pharmacy in rural Mayville, WI, pharmacy technicians were observed before and 3 months after installation of an automated robotic prescription-filling device. The main outcome measures were sequences and timing of technician workflow steps, workflow interruptions, automation surprises, and workarounds. Results Of the 77 and 80 observations made before and 3 months after robot installation, respectively, 17 different workflow sequences were observed before installation and 38 after installation. Average prescription filling time was reduced by 40 seconds per prescription with use of the robot. Workflow interruptions per observation increased from 1.49 to 1.79 (P = 0.11), and workarounds increased from 10% to 36% after robot use. Conclusion Although automated prescription-filling devices can increase efficiency, workflow interruptions and workarounds may negate that efficiency. Assessing changes in workflow and sequencing of tasks that may result from the use of automation can help uncover opportunities for workflow policy and procedure redesign. PMID:21896459

In structures or equipment made of stainless steel, Ni-based alloy or a low alloy steel and undergoing neutron irradiation and causing a crack-like defect in a reactor pressure vessel, a plate is applied to a region where the crack-like detect is caused, and pressure is applied locally to bond the plate by generated resistance. Namely, electric current is supplied to the portion to be bonded while pressurizing to bond it by generated resistance heat. Then the propagation of cracks can be prevented and occurrence of cracks upon repairing can be prevented relative to a structural member undergoing neutron irradiation in the reactor pressure vessel and causing a crack-like defect thereby enabling to provide effects of preventing occurrence of an accident due to stress corrosion cracking of a nuclear power plant and prolonging the integrity of the plant.

Contact dermatoses are common in mechanic and repair occupations. This study aimed to (1) estimate the prevalence of occupationally related contact dermatitis among mechanics/repairers patch tested from 1998 to 2014 by the North American Contact Dermatitis Group, (2) characterize responsible allergens and irritants, and their sources, and (3) compare results among 3 occupational subgroups (mechanics, electrical/electronic, and other). A cross-sectional analysis of patients patch tested by the North American Contact Dermatitis Group between 1998 and 2014. Of 38,784 patients patch tested, 691 (1.8%) were mechanics/repairers. Male sex (93.5%) and hand involvement (59.5%) were common overall. Occupationally related skin disease was more prevalent among vehicle and mobile equipment mechanics/repairers (52.7%) and other mechanics/repairers (41.4%) than electrical/electronic equipment mechanics/repairers (21.3%). Overall, carba mix, thiuram mix, and methylchloroisothiazolone/methylisothiazolone were the most common occupation-related clinically relevant allergens. Gloves, automotive vehicles, solvents, oils, lubricants, and fuels were the most common sources of responsible allergens. Common occupationally related allergens included rubber accelerators and the preservative methylchloroisothiazolone/methylisothiazolone.

Correct use of a child safety seat (CSS) can reduce the risk of fatal motor vehicle crash-related injury by up to 71%; however, misuse rates for CSS are as high as 70%. We recruited 189 caregivers at 2 large suburban pediatric office practices; 94 in the intervention group and 95 in the control group. All participants completed a baseline survey and received a CSS safety brochure. Intervention participants had their CSS installation checked at enrollment by a certified child passenger safety (CPS) technician. Follow-up was conducted 4 months post enrollment. Intervention group participants had a 21.3% reduction in critical misuse at follow-up, whereas control participants critical misuse rate at follow-up was identical to the intervention group at baseline. A consult with a certified CPS technician, at the time of a routine visit to the pediatrician, resulted in a reduction in CSS misuse rates.

CrowdAidRepair: A Crowd-Aided Interactive Data Repairing Method

KAUST Repository

Zhou, Jian

2016-03-25

Data repairing aims at discovering and correcting erroneous data in databases. Traditional methods relying on predefined quality rules to detect the conflict between data may fail to choose the right way to fix the detected conflict. Recent efforts turn to use the power of crowd in data repairing, but the crowd power has its own drawbacks such as high human intervention cost and inevitable low efficiency. In this paper, we propose a crowd-aided interactive data repairing method which takes the advantages of both rule-based method and crowd-based method. Particularly, we investigate the interaction between crowd-based repairing and rule-based repairing, and show that by doing crowd-based repairing to a small portion of values, we can greatly improve the repairing quality of the rule-based repairing method. Although we prove that the optimal interaction scheme using the least number of values for crowd-based repairing to maximize the imputation recall is not feasible to be achieved, still, our proposed solution identifies an efficient scheme through investigating the inconsistencies and the dependencies between values in the repairing process. Our empirical study on three data collections demonstrates the high repairing quality of CrowdAidRepair, as well as the efficiency of the generated interaction scheme over baselines.

To provide baseline levels of job satisfaction and stress among members of the long-term care pharmacy team participating in the Fleetwood Phase III evaluation. Cross-sectional design; long-term care pharmacy provider in North Carolina (the implementation site of the large-scale Fleetwood Phase III study). All current pharmacy employees as of May/June 2002. None. Health Professional Stress Inventory and job satisfaction. Ninety-four percent (16/17) of consultant pharmacists were satisfied with their job, with 89% reporting they would definitely choose to be a pharmacist again. Seventy-five percent both of dispensing pharmacists and pharmacy technicians reported overall job satisfaction. Forty-one reported that they would not choose to be a pharmacist (pharmacy technician) again. The most frequently reported sources of stress among the dispensing pharmacists and pharmacy technicians were conflicts with non-work obligations (i.e., family, personal life) and the ability to perform duties with short staffing. In addition, inadequate pay and few opportunities for job advancement were often/frequent sources of stress among pharmacy technicians. More than one third of dispensing pharmacists also reported stress frequently because of fears of mistakes in patient treatment. Overall, consultants are very satisfied with their positions, although dispensing pharmacists and pharmacy technicians are less satisfied with their work. The reasons may be because of the different nature of each job, as well as staffing shortages. The extent to which the Fleetwood Model can improve job satisfaction and impact on stress will be evaluated once we resurvey the pharmacy team after the intervention period of the Fleetwood Phase III study.

Dental technicians are exposed to methyl methacrylate(MMA) and hard metal dusts while working, and several cases of hypersensitivity pneumonitis caused by the exposure have been reported. The authors experienced a case of hypersensitivity pneumonitis in a female dental technician who had 10 years' work experience and report the case with clinical evidence. The patient's work, personal, social, and past and present medical histories were investigated based on patient questioning and medical records. Furthermore, the workplace conditions and tools and materials the patient worked with were also evaluated. Next, the pathophysiology and risk factors of pneumonitis were studied, and studies on the relationship between hypersensitivity pneumonitis and a dental technician's exposure to dust were reviewed. Any changes in the clinical course of her disease were noted for evaluation of the work-relatedness of the disease. The patient complained of cough and sputum for 1 year. In addition, while walking up the stairs, the patient was not able to ascend without resting due to dyspnea. She visited our emergency department due to epistaxis, and secondary hypertension was incidentally suspected. Laboratory tests including serologic, electrolyte, and endocrinologic tests and a simple chest radiograph showed no specific findings, but chest computed tomography revealed a centrilobular ground-glass pattern in both lung fields. A transbronchial biopsy was performed, and bronchoalveolar washing fluid was obtained. Among the findings of the laboratory tests, microcalcification, noncaseating granuloma containing foreign body-type giant cells, and metal particles within macrophages were identified histologically. Based on these results, hypersensitivity pneumonitis was diagnosed. The patient stopped working due to admission, and she completely quit her job within 2 months of restarting work due to reappearance of the symptoms. In this study, the patient did not have typical radiologic

Introducing a checking technician allows pharmacists to spend more time on patient-focused activities.

Science.gov (United States)

Napier, Patti; Norris, Pauline; Braund, Rhiannon

2018-04-01

Internationally there is an increasing focus on the clinical and cognitive services that pharmacists can provide. Lack of time has been identified as a barrier to pharmacists increasing their clinical activities. Within the pharmacy workplace there are many tasks that can only be performed by a pharmacist. The final accuracy check of a dispensed prescription is currently the sole responsibility of pharmacists in New Zealand. This takes up a significant amount of time during a pharmacist's work day. The introduction of a checking technician role has been suggested to allow pharmacists more time to do more patient focused work. To investigate the amount of time pharmacy staff spend on specific activities and to establish whether the introduction of a checking technician into twelve pilot sites increased the amount of time that the pharmacists could spend on patient focused activities. This study utilised a self-reported work sampling technique in twelve pilot sites, selected from both the hospital and community settings. Work sampling using an electronic device was conducted at two time-points (before the implementation of a Pharmacy Accuracy Checking Technician (PACT) role and when the PACT was in place). Data was collected at 10 min intervals for the period of five days, a working week. Tasks were grouped into patient focused, dispensing and personal activities. The introduction of the PACT into the pilot sites saw a mean increase of 19% in pharmacists' patient focused activities and a mean 20% decrease in dispensing activities. The introduction of a checking technician role into New Zealand pharmacies demonstrated the potential to provide pharmacists with more time to spend on patient focused activities.

2018-04-01

Refractory ceramic fibers (RCF) have been extensively used for insulation in condensing boilers. The aim of this study was to evaluate the respiratory exposure to these fibers among maintenance heating technicians. We first created a working group (Carsat Brittany and Finistère Occupational Health Services) and carried out a sampling strategy. Atmospheric measurements were done during work tasks, and filters were analyzed by phase contrast microscopy (PCM) and scanning electron microscopy (SEM) in French approved laboratories. Four companies were included for a total of 15 days of work. During those 15 workdays, 12 SEM and 21 PCM samples were taken and analyzed. The phase contrast microscopy and SEM average results were 0.04 and 0.004 fibers/cm 3 , respectively. In conclusion, the study confirms heating technician RCF respiratory exposure during maintenance work for both condensation gas boilers and atmospheric boilers. Collective and individual prevention measures should be implemented along with appropriate medical follow-up.

Evidence-based approach to the maintenance of laboratory and medical equipment in resource-poor settings.

Science.gov (United States)

Malkin, Robert; Keane, Allison

2010-07-01

Much of the laboratory and medical equipment in resource-poor settings is out-of-service. The most commonly cited reasons are (1) a lack of spare parts and (2) a lack of highly trained technicians. However, there is little data to support these hypotheses, or to generate evidence-based solutions to the problem. We studied 2,849 equipment-repair requests (of which 2,529 were out-of-service medical equipment) from 60 resource-poor hospitals located in 11 nations in Africa, Europe, Asia, and Central America. Each piece of equipment was analyzed by an engineer or an engineering student and a repair was attempted using only locally available materials. If the piece was placed back into service, we assumed that the engineer's problem analysis was correct. A total of 1,821 pieces of medical equipment were placed back into service, or 72%, without requiring the use of imported spare parts. Of those pieces repaired, 1,704 were sufficiently documented to determine what knowledge was required to place the equipment back into service. We found that six domains of knowledge were required to accomplish 99% of the repairs: electrical (18%), mechanical (18%), power supply (14%), plumbing (19%), motors (5%), and installation or user training (25%). A further analysis of the domains shows that 66% of the out-of-service equipment was placed back into service using only 107 skills covering basic knowledge in each domain; far less knowledge than that required of a biomedical engineer or biomedical engineering technician. We conclude that a great majority of laboratory and medical equipment can be put back into service without importing spare parts and using only basic knowledge. Capacity building in resource-poor settings should first focus on a limited set of knowledge; a body of knowledge that we call the biomedical technician's assistant (BTA). This data set suggests that a supported BTA could place 66% of the out-of-service laboratory and medical equipment in their hospital back

The first dedicated PET/CT centre in Norway was established at the Norwegian Radiumhospital in Oslo in 2005. Knowing that the introductions of PET-isotopes in nuclear medicine give increased occupational radiation dose to the technicians, a study was carried out in order to map the doses to staff members during different working operations and to see if any dose reducing measures were needed. The results of the study are in good agreement with other studies, and a technician dose of 20-25 nSv per injected MBq of 18 F seems to be representative for such centres. For an average injected activity of 350 MBq per patient, the dose limit is reached after handling around 3000 patients annually. For an annual number of less than 500 patients at the centre and rotation of the staff, an annual individual dose for the technicians would realistically be less than 2-3 mSv. Even a major increase in the number of patients will not result in individual doses near the ICRP dose limit. (authors)

Schultz, Daniel Clyde

Commercial aviation and commercial space similarly launch, fly, and land passenger vehicles. Unlike aviation, the U.S. government has not established maintenance policies for commercial space. This study conducted a mixed methods review of 610 U.S. space launches from 1984 through 2011, which included 31 failures. An analysis of the failure causal factors showed that human error accounted for 76% of those failures, which included workmanship error accounting for 29% of the failures. With the imminent future of commercial space travel, the increased potential for the loss of human life demands that changes be made to the standardized procedures, training, and certification to reduce human error and failure rates. Several recommendations were made by this study to the FAA's Office of Commercial Space Transportation, space launch vehicle operators, and maintenance technician schools in an effort to increase the safety of the space transportation passengers.

2014-02-01

This paper analyzes the severity of workplace accidents involving electricity in the Spanish construction sector comprising 2,776 accidents from 2003 to 2008. The investigation considered the impact of 13 variables, classified into 5 categories: Personal, Business, Temporal, Material, and Spatial. The findings showed that electrical accidents are almost five times more likely to have serious consequences than the average accident in the sector and it also showed how the variables of age, occupation, company size, length of service, preventive measures, time of day, days of absence, physical activity, material agent, type of injury, body part injured, accident location, and type of location are related to the severity of the electrical accidents under consideration. The present situation makes it clear that greater effort needs to be made in training, monitoring, and signage to guarantee a safe working environment in relation to electrical hazards. This research enables safety technicians, companies, and government officials to identify priorities and to design training strategies to minimize the serious consequences of electrical accidents for construction workers.

Royal Engineer Geographic Technicians: Exploring their attitudes to education and training

Science.gov (United States)

Knight, John Anthony

A creative approach is presented for understanding the attitudes of Royal Engineer (RE) Geographic Technicians (Geo Techs) to training and education. Through a grounded theory methodology, participants' experiences of learning and teaching are explored. These provide a greater awareness and perception of attitudes than have emerged through more established, formal methods of evaluating the effectiveness of training. Recent developments in technology, doctrine, requirements and operations have brought about significant changes to the range and complexity of subjects taught in the field of Geospatial Intelligence (GEOINT). This in turn has increased the challenges to RE staff and students, many of whom find themselves instructing on or undertaking demanding degree level courses without the requisite formal qualifications. Grounded theory, based on guidelines rather than rigid rules, is adopted to provide a study of RE Geographic Technicians' learning experiences from the perspective of those who live it and for an interpretive understanding of their meanings to emerge. The policies, culture and social processes in which the RE Geo training takes place are explored to appreciate the influence of the training environment on learning. Data obtained through focus groups held with students and instructors, and through in-depth interviews with individuals who hold key roles associated with the course, recognises the relativism of multiple social realities in developing a rich source of knowledge on attitudes to learning. The collection, synthesis and analysis of data led to the emergence of core categories: context, commitment, expectations, motivation, qualifications, relevance and respect. Through their engagement the research participants' awareness, in particular of instructors, of Geographic Technicians' attitudes to training and education has been raised. Using the theoretical framework of communities of practice, the challenges and effectiveness of the RSMS as a

An apparatus is introduced for the use of enhancing tissue repair in mammals. The apparatus includes a sleeve; an electrically conductive coil; a sleeve support; an electrical circuit configured to supply the coil with a square wave time varying electrical current sufficient to create approximately 0.05 gauss to 0.5 gauss. When in use, the sleeve of the apparatus is placed on a mammalian body part and the time varying electromagnetic force of from approximately 0.05 gauss to 0.5 gauss is generated on the mammalian body for an extended period of time so that the tissue is encouraged to be regenerated in the mammalian body part at a rate in excess of the normal tissue regeneration rate relative to regeneration without application of the time varying electromagnetic force.

1977-01-01

From the nine health surveys made on clinical radiation technicians working at health centers during the 18 years from 1957 to 1975, 679 technicians on whom blood examinations were made for not less than ten consecutive years were sampled to investigate for chronological alterations in their blood parameters. The radiation protective means at the health centers have made rapid progress ever since the atomic bomb experiment in 1954, and the dose of exposure to radiation then began to decrease. On the other hand, it was in about 1960 that the measurement of individual exposure doses began to be made on 60% of all the technicians. Chronological alterations in the average blood counts of these technicians under the abovementioned situation were such that RBC and hemoglobin level continued to increase from 1963 until about 1967, but then began to decrease, and that WBC was as low as 5,883/mm 3 in 1957, but tended to increase though slightly at each of the subsequent surveys, and was increased to 6,570/mm 3 in 1975, that is, WBC has been approaching the normal count of 6,774/mm 3 in the Japanese, with a significant difference at a not more than 1% level of significance in each survey year. For the purpose of preventing radiation hazard, further efforts should be made to protect the technicians from exposure to radiation and to control their health. (auth.)

Integrating Safety in the Aviation System: Interdepartmental Training for Pilots and Maintenance Technicians

Mattson, Marifran; Petrin, Donald A.; Young, John P.

2001-01-01

The study of human factors has had a decisive impact on the aviation industry. However, the entire aviation system often is not considered in researching, training, and evaluating human factors issues especially with regard to safety. In both conceptual and practical terms, we argue for the proactive management of human error from both an individual and organizational systems perspective. The results of a multidisciplinary research project incorporating survey data from professional pilots and maintenance technicians and an exploratory study integrating students from relevant disciplines are reported. Survey findings suggest that latent safety errors may occur during the maintenance discrepancy reporting process because pilots and maintenance technicians do not effectively interact with one another. The importance of interdepartmental or cross-disciplinary training for decreasing these errors and increasing safety is discussed as a primary implication.

The use of animals in research is controversial and often takes place under a veil of secrecy. Lab animal technicians responsible for the care of animals at research institutions are sometimes described as performing 'dirty work' (i.e. professions that are viewed as morally tainted), and may be stigmatized by negative perceptions of their job. This study assessed if transparency affects public perceptions of lab animal technicians and support for animal research. Participants (n = 550) were randomly assigned to one of six scenarios (using a 3x2 design) that described identical research varying only the transparency of the facility (low, high) and the species used (mice, dogs, cows). Participants provided Likert-type and open-ended responses to questions about the personal characteristics (warmth, competence) of a hypothetical lab technician 'Cathy' and their support for the described research. Quantitative analysis showed participants in the low-transparency condition perceived Cathy to be less warm and were less supportive of the research regardless of animal species. Qualitative responses varied greatly, with some participants expressing support for both Cathy and the research. These results suggest that increasing transparency in lab animal institutions could result in a more positive perception of lab animal researchers and the work that they do.

The purpose of this study was to analyze the effectiveness of an online medical laboratory technician program in the academic preparation and development of laboratory professionals. A semi-quantitative comparative research design was used. Several factors were considered in this evaluation. Academic outcomes between online and campus medical laboratory technician (MLT) students was determined by comparing overall and categorical scores on certification exams as well as first time pass rate. Certification exam scores and first time pass rates were also compared to national norms when possible to do so. Demographic data, including age and experience were compared. Additionally, learning styles were assessed to determine if there was a correlation to overall GPA and MLT GPA and if learning styles could be used to predict successful completion of an online Associates of Applied Science. The research was conducted at an academic university located in the mountain west United States. Participants consisted of online and campus students enrolled in a Medical Laboratory Technician program that graduated with their Associate of Applied Science degree between the years 2007-2009. Results of these years were also compared to graduates from 2004-2006 in the same program. Certification performance and first time pass rates were the major outcomes measured. Age and experience were correlated. Online learning styles and GPA were also compared to successful degree completion. The researcher found no significant difference in certification performance with regard to total and categorical scores, and first time pass rates between campus and online MLT students. Online students were slightly older and had more experience working in a laboratory in some capacity. Correlation studies showed significant positive correlation between learning styles, GPA, and successful completion of an Associate of Applied Science degree. When registry scores were compared to the prior cohort of online

Repairable-conditionally repairable damage model based on dual Poisson processes.

2003-09-01

The advent of intensity-modulated radiation therapy makes it increasingly important to model the response accurately when large volumes of normal tissues are irradiated by controlled graded dose distributions aimed at maximizing tumor cure and minimizing normal tissue toxicity. The cell survival model proposed here is very useful and flexible for accurate description of the response of healthy tissues as well as tumors in classical and truly radiobiologically optimized radiation therapy. The repairable-conditionally repairable (RCR) model distinguishes between two different types of damage, namely the potentially repairable, which may also be lethal, i.e. if unrepaired or misrepaired, and the conditionally repairable, which may be repaired or may lead to apoptosis if it has not been repaired correctly. When potentially repairable damage is being repaired, for example by nonhomologous end joining, conditionally repairable damage may require in addition a high-fidelity correction by homologous repair. The induction of both types of damage is assumed to be described by Poisson statistics. The resultant cell survival expression has the unique ability to fit most experimental data well at low doses (the initial hypersensitive range), intermediate doses (on the shoulder of the survival curve), and high doses (on the quasi-exponential region of the survival curve). The complete Poisson expression can be approximated well by a simple bi-exponential cell survival expression, S(D) = e(-aD) + bDe(-cD), where the first term describes the survival of undamaged cells and the last term represents survival after complete repair of sublethal damage. The bi-exponential expression makes it easy to derive D(0), D(q), n and alpha, beta values to facilitate comparison with classical cell survival models.

Kluger, M T; Bryant, J

2008-03-01

Anaesthetic technicians play a key role in the operating room, yet little is known about their levels of job satisfaction or workplace stress. A blinded, confidential single mail-out survey was posted to anaesthetic technicians in New Zealand. The survey consisted of demographic information, a job satisfaction survey, the Maslach Burnout Inventory and the Short Form 12. At total of 154 forms were returned (51% response rate). Respondents worked predominantly in public hospitals and many had duties outside the operating room. Job satisfaction was related to teamwork, practical nature of work and patient contact, while dissatisfaction was related to lack of respect from nurses and limited career pathway. High to moderate levels of emotional exhaustion (48%), depersonalisation (39%) and low levels of personal accomplishment (58%) were indicators of burnout. The Short Form 12 revealed high levels of physical impairment in 24% and emotional impairment in 35% of respondents. These data suggest that work is needed to evaluate anaesthetic assistants' job structure and actively manage their important physical and emotional sequelae.

Imaging technicians working with magnetic resonance imaging (MRI) may experience acute effects such as vertigo or dizziness when being exposed. A previous study also reported an increased risk of accidents in MRI exposed staff. We aimed at evaluating commuting accident risk in Dutch imaging technicians. Of invited imaging technicians, 490 (29%) filled in a questionnaire pertaining to (near) accidents when driving or riding a bike, health, lifestyle and work practices. We used logistic regression to evaluate the association between exposure to MRI-related electromagnetic fields and risk of commuting (near) accidents in the year prior to the survey, adjusted for a range of potential confounders. Our cross-sectional study indicated an increased risk of (near) accidents if imaging technicians had worked with MRI in the year prior to the survey (odds ratio OR 2.13, 95%CI 1.23-3.69). Risks were higher in persons who worked with MRI more often (OR 2.32, 95%CI 1.25-4.31) compared to persons who worked sometimes with MRI (OR 1.91, 95%CI 0.98-3.72), and higher in those who had likely experienced higher peak exposures to static and time-varying magnetic fields (OR 2.18, 95%CI 1.06-4.48). The effect was seen on commuting accidents that had occurred on the commute from home to work as well as accidents from work to home or elsewhere. Imaging technicians working with MRI scanners may be at an increased risk of commuting (near) accidents. This result needs confirmation and potential risks for other groups (volunteers, patients) should be investigated. Copyright © 2017 Elsevier Inc. All rights reserved.

Tissue repair capacity and repair kinetics deduced from multifractionated or continuous irradiation regimens with incomplete repair

International Nuclear Information System (INIS)

Thames, H.D. Jr.; Peters, L.J.

1984-01-01

A model is proposed for cell survival after multiple doses, when the interfraction interval is insufficient for complete Elkind repair. In the limit of ever-increasing number of ever-smaller fractional doses, the model transforms into the accumulation model of survival after continuous irradiation. When adapted to describe tissue responses to isoeffective multifractionated regimens, wherein repair is incomplete, a generalization of the usually linear plot of reciprocal total dose versus dose per fraction is obtained, in which downward curvature is evident. There is an advantage in studying tissue responses to multifractionated regimens with incomplete repair in the interfraction intervals, or continuous exposures at various dose rates since, in addition to determination of repair capacity, there is an estimate of repair kinetics. Results of analyses of previously published data are presented as illustration. Estimated from the response of three acutely responding normal tissues in the mouse (jejunum, colon and bone marrow), repair halftimes ranged from 0.3-0.9 h and values of β/delta were approximately 0.1 Gy -1 . From the response of mouse lung (LD50 for pneumonitis) to multifractionated regimens with incomplete repair, the repair halftime was estimated at 1.5 h and β/delta was 0.27 Gy -1 . In the rat spinal cord β/delta was 0.7 Gy -1 and Tsub(1/2) was 1.5 h. (U.K.)

The aim of the study was to compare biomechanical strength, repair times, and repair values for zone II core flexor tendon repairs. A total of 75 fresh-frozen human cadaveric flexor tendons were harvested from the index through small finger and randomized into one of 5 repair groups: 4-stranded cross-stitch cruciate (4-0 polyester and 4-0 braided suture), 4-stranded double Pennington (2-0 knotless barbed suture), 4-stranded Pennington (4-0 double-stranded braided suture), and 6-stranded modified Lim-Tsai (4-0 looped braided suture). Repairs were measured in situ and their repair times were measured. Tendons were linearly loaded to failure and multiple biomechanical values were measured. The repair value was calculated based on operating room costs, repair times, and suture costs. Analysis of variance (ANOVA) and Tukey post hoc statistical analysis were used to compare repair data. The braided cruciate was the strongest repair ( P > .05) but the slowest ( P > .05), and the 4-stranded Pennington using double-stranded suture was the fastest ( P > .05) to perform. The total repair value was the highest for braided cruciate ( P > .05) compared with all other repairs. Barbed suture did not outperform any repairs in any categories. The braided cruciate was the strongest of the tested flexor tendon repairs. The 2-mm gapping and maximum load to failure for this repair approached similar historical strength of other 6- and 8-stranded repairs. In this study, suture cost was negligible in the overall repair cost and should be not a determining factor in choosing a repair.

To determine the influence of several factors on standard automated perimetry test results in glaucoma. Longitudinal Humphrey field analyzer 30-2 Swedish interactive threshold algorithm data from 160 eyes of 160 glaucoma patients were used. The influence of technician experience, time of day, and season on the mean deviation (MD) was determined by performing linear regression analysis of MD against time on a series of visual fields and subsequently performing a multiple linear regression analysis with the MD residuals as dependent variable and the factors mentioned above as independent variables. Analyses were performed with and without adjustment for the test reliability (fixation losses and false-positive and false-negative answers) and with and without stratification according to disease stage (baseline MD). Mean follow-up was 9.4 years, with on average 10.8 tests per patient. Technician experience, time of day, and season were associated with the MD. Approximately 0.2 dB lower MD values were found for inexperienced technicians (P Technician experience, time of day, season, and the percentage of false-positive answers have a significant influence on the MD of standard automated perimetry.

Hill, John D; Anderegg, Sammuel V; Couldry, Rick J

2017-10-01

Background: Influenza and pneumococcal disease contribute substantially to the burden of preventable disease in the United States. Despite quality measures tied to immunization rates, health systems have struggled to achieve these targets in the inpatient setting. Pharmacy departments have had success through implementation of pharmacist standing order programs (SOP); however, these initiatives are labor-intensive and have not resulted in 100% immunization rates. Objective: The objective of this study was to evaluate a pilot utilizing pharmacy technician interventions, in combination with a nursing SOP, to improve vaccination rates of hospitalized patients for influenza and pneumococcal disease. Methods: A process was developed for pharmacy technicians to identify patients who were not previously screened or immunized during the weekend days on the Cardiovascular Progressive Care unit at the University of Kansas Health-System. Targeted pharmacy technician interventions consisted of phone call reminders and face-to-face discussions with nursing staff. The primary study outcome was the change in immunization compliance rates between the control and intervention groups. Results: Influenza vaccine rates showed a statistically significant increase from 72.2% (52 of 72) of patients during the control group to 92.9% (65 of 70, P = .001) of patients during the intervention group. A pneumococcal vaccination rate of 81.3% (61 of 75) was observed in the control group, compared with 84.3% (59 of 70) of patients in the intervention group ( P = .638). Conclusion: An improvement in inpatient influenza immunization rates can be achieved through targeted follow-up performed by pharmacy technicians, in combination with a nursing-driven SOP.

Registered nurses in the district nursing service delegate a broad range of medication administration activities to healthcare assistants. Although healthcare assistants have provided extra capacity, not all activities are suitable for delegation to unregulated practitioners. At the same time, their competency assessment is often patient-specific and demands significant registered nursing input. The purpose of this 6-month pilot programme was to test the premise that the employment of a pharmacy technician in the district nursing service would enhance productivity levels and deliver cost savings. Activities delegated included the administration of oral tablets and subcutaneous insulin and low molecular weight heparin injections. The evaluation found that the introduction of the pharmacy technician was associated with neither enhanced productivity nor more than modest cost savings. However, role redesign is a long-term activity and their role could be built on with further competency analysis.

Medication discrepancies are common when patients cross organisational boundaries. However, little is known about the frequency of discrepancies within mental health and the efficacy of interventions to reduce discrepancies. To evaluate the impact of a pharmacy-led reconciliation service on medication discrepancies on admissions to a secondary care mental health trust. In-patient mental health services. Prospective evaluation of pharmacy technician led medication reconciliation for admissions to a UK Mental Health NHS Trust. From March to June 2012 information on any unintentional discrepancies (dose, frequency and name of medication); patient demographics;and type and cause of the discrepancy was collected. The potential for harm was assessed based on two scenarios; the discrepancy was continued into primary care, and the discrepancy was corrected during admission. Logistic regression identified factors associated with discrepancies. Mean number of discrepancies per admission corrected by the pharmacy technician. Unintentional medication discrepancies occurred in 212 of 377 admissions (56.2 %). Discrepancies involving 569 medicines (mean 1.5 medicines per admission) were corrected.The most common discrepancy was omission(n = 464). Severity was assessed for 114 discrepancies. If the discrepancy was corrected within 16 days the potential harm was minor in 71 (62.3 %) cases and moderate in 43(37.7 %) cases whereas if the discrepancy was not corrected the potential harm was minor in 27 (23.7 %) cases and moderate in 87 (76.3 %) cases. Discrepancies were associated with both age and number of medications; the stronger association was age. Medication discrepancies are common within mental health services with potentially significant consequences for patients.Trained pharmacy technicians are able to reduce the frequency of discrepancies, improving safety.

Burkhart, Stephen S; Denard, Patrick J; Obopilwe, Elifho; Mazzocca, Augustus D

2012-02-01

The purpose of this study was to compare tendon-bone footprint contact area over time under physiologic loads for 4 different rotator cuff repair techniques: single row (SR), triangle double row (DR), chain-link double row (CL), and diamondback double row (DBK). A supraspinatus tear was created in 28 human cadavers. Tears were fixed with 1 of 4 constructs: SR, DR, CL, or DBK. Immediate post-repair measurements of pressurized contact area were taken in neutral rotation and 0° of abduction. After a static tensile load, pressurized contact area was observed over a 160-minute period after repair. Cyclic loading was then performed. The DBK repair had the highest pressurized contact area initially, as well as the highest pressurized contact area and lowest percentage decrease in pressurized contact area after 160 minutes of testing. The DBK repair had significantly larger initial pressurized contact than CL (P = .003) and SR (P = .004) but not DR (P = .06). The DBK technique was the only technique that produced a pressurized contact area that exceeded the native footprint both at initial repair (P = .01) and after 160 minutes of testing (P = .01). DBK had a significantly larger mean pressurized contact area than all the repairs after 160 minutes of testing (P = .01). DBK had a significantly larger post-cyclic loading pressurized contact area than CL (P = .01) and SR (P = .004) but not DR (P = .07). This study showed that a diamondback repair (a modification of the transosseous repair) can significantly increase the rotator cuff pressurized contact area in comparison with other standard rotator cuff repair constructs when there is sufficient tendon mobility to perform a double-row repair without excessive tension on the repair site. The persistent pressurized contact area of a DBK repair may be desirable to enhance healing potential when there is sufficient tendon mobility to perform a double-row repair, particularly for large or massive rotator cuff tears where it is

Drug diversion by health care personnel poses a risk for serious patient harm. Public health identified 2 patients diagnosed with acute hepatitis C virus (HCV) infection who shared a common link with a hospital. Further investigation implicated a drug-diverting, HCV-infected surgical technician who was subsequently employed at an ambulatory surgical center. Patients at the 2 facilities were offered testing for HCV infection if they were potentially exposed. Serum from the surgical technician and patients testing positive for HCV but without evidence of infection before their surgical procedure was further tested to determine HCV genotype and quasi-species sequences. Parenteral medication handling practices at the 2 facilities were evaluated. The 2 facilities notified 5970 patients of their possible exposure to HCV, 88% of whom were tested and had results reported to the state public health departments. Eighteen patients had HCV highly related to the surgical technician's virus. The surgical technician gained unauthorized access to fentanyl owing to limitations in procedures for securing controlled substances. Public health surveillance identified an outbreak of HCV infection due to an infected health care provider engaged in diversion of injectable narcotics. The investigation highlights the value of public health surveillance in identifying HCV outbreaks and uncovering a method of drug diversion and its impacts on patients.

The gadoxetate-enhanced liver MR images of 30 patients acquired using the traditional breathing command and the subsequent 30 patients after training the technicians to use a modified breathing command were analyzed. A subgroup of patients (n = 8) underwent scans both by trained and untrained technicians. Images obtained using the traditional and modified breathing command were compared for the presence of breathing artefacts [respiratory artefact-based image quality scores from 1 (best) to 5 (non-diagnostic)]. There was a highly significant improvement in the arterial phase image quality scores in patients using the modified breathing command compared to the traditional one (P < 0.001). The percentage of patients with severe and extensive breathing artefacts in the arterial phase decreased from 33.3 % to 6.7 % after introducing the modified breathing command (P = 0.021). In the subgroup that underwent MRI using both breathing commands, arterial phase image quality improved significantly (P = 0.008) using the modified breathing command. Training technicians to use a modified breathing command significantly improved arterial phase image quality of gadoxetate-enhanced liver MRI. (orig.)

Full Text Available Introduction: The objective of this study was to evaluate emergency medicine physician and nurse acceptance of nonnurse, nonphysician screening for geriatric syndromes. Methods: This was a single-center emergency department (ED survey of physicians and nurses after an 8-month project. Geriatric technicians were paid medical student research assistants evaluating consenting ED patients older than 65 years for cognitive dysfunction, fall risk, or functional decline. The primary objective of this anonymous survey was to evaluate ED nurse and physician perceptions about the geriatric screener feasibility and barriers to implementation. In addition, as a secondary objective, respondents reported ongoing geriatric screening efforts independent of the research screeners. Results: The survey was completed by 72% of physicians and 33% of nurses. Most nurses and physicians identified geriatric technicians as beneficial to patients without impeding ED throughput. Fewer than 25% of physicians routinely screen for any geriatric syndromes. Nurses evaluated for fall risk significantly more often than physicians, but no other significant differences were noted in ongoing screening efforts. Conclusion: Dedicated geriatric technicians are perceived by nurses and physicians as beneficial to patients with the potential to improve patient safety and clinical outcomes. Most nurses and physicians are not currently screening for any geriatric syndromes. [West J Emerg Med. 2011;12(4:489–495.

A method is presented to self-repair cracks in embedded silver grid structures used in large area organic electronics. The repair procedure is based on electro-deposition, incited by the application of a moderate DC voltage across the crack. During this process the organic anode that is in direct electrical contact with the silver grid, functions as an appropriate medium for ion migration. Restoration of conductivity is achieved by the formation of dendritic metal structures that connect the cathodic to the anodic side of the crack. The metal dendrites decrease the gap resistance by one order of magnitude. Subsequently, another three orders of magnitude are gained upon sintering the dendrites using a high voltage pulse, yielding restored conductance levels nearly within one order of magnitude difference from native track conductance. - Highlights: • An innovative method to repair cracks in embedded silver electrodes is presented. • The method targets application in flexible hybrid- and organic electronics. • The mechanism relies on dendritic growth of metallic structures. • Sintering yields restored conductivity levels approaching the original value.

Methods for training radiochemical technicians at ORNL

International Nuclear Information System (INIS)

Parrott, J.R.; Nicol, R.G.

The training of personnel to carry out radiochemical operations at ORNL is a formidable and recurrent task since programs are constantly shifting. It is essential that provisions be made for the routine retraining of these personnel if they are to make effective contributions on a continuing basis. Training methods are described that have emerged as a result of thirty years experience in a variety of radiochemical pilot-plant programs. Emphasis is placed on training programs for technicians for the 233 U Processing Facility since essentially all aspects of radiochemical operations are encountered in this facility. These programs have included operations performed in glove boxes, hot-cell manipulator work handling high-neutron-emitting isotopes, and the entire spectrum of remote solvent extraction operations.

To evaluate the impact of a pharmacy-technician centered medication reconciliation (PTMR) program by identifying and quantifying medication discrepancies and outcomes of pharmacist medication reconciliation recommendations. A retrospective chart review was performed on two-hundred patients admitted to the internal medicine teaching services at Cooper University Hospital in Camden, NJ. Patients were selected using a stratified systematic sample approach and were included if they received a pharmacy technician medication history and a pharmacist medication reconciliation at any point during their hospital admission. Pharmacist identified medication discrepancies were analyzed using descriptive statistics, bivariate analyses. Potential risk factors were identified using multivariate analyses, such as logistic regression and CART. The priority level of significance was set at 0.05. Three-hundred and sixty-five medication discrepancies were identified out of the 200 included patients. The four most common discrepancies were omission (64.7%), non-formulary omission (16.2%), dose discrepancy (10.1%), and frequency discrepancy (4.1%). Twenty-two percent of pharmacist recommendations were implemented by the prescriber within 72 hours. A PTMR program with dedicated pharmacy technicians and pharmacists identifies many medication discrepancies at admission and provides opportunities for pharmacist reconciliation recommendations.

Full Text Available The reliability and performance of a steam generator (SG is one of the serious concerns in the operation of pressurized water nuclear power plants. Because of high levels of radiation, robotic systems have been used to inspect and repair SG tubes. In this paper, we present a mobile robotic system that positions the inspection and repair tools while hanging down from the tube sheets where the tubes are fixed. All of the driving mechanisms of the mobile robot are actuated by electric motors to start its works, providing that the electric power is prepared without the additional need for an on-site air services. A special tube-holding mechanism with a high holding force has been developed to prevent falling from the tube sheets, even in the case of an electric power failure. We have also developed a quick installation guide device that guides the mobile robot to desired initial positions in the tube sheet exactly and quickly, which helps to reduce the radiation exposure of human workers during the installation work. This paper also provides on-site experimental results and lessons learned.

Adhesive liquid core optical fibers for crack detection and repairs in polymer and concrete matrices

Science.gov (United States)

Dry, Carolyn M.

1995-04-01

This work is an investigation into the feasibility of using liquid core optical fibers for the detection and self repair of cracking in cement or polymer materials generated by dynamic or static loading. These experiments rely on our current research sponsored by the National Science Foundation. It combines that work on the concept of internal adhesive delivery from hollow fibers for repair with nondestructive fiber optic analysis of the crack localization and volume within the same system. The need to monitor the internal state of civil structures and materials is great. Existing instrumentation techniques that mainly rely on magnetism, electricity, or stress gauges are limited if used for remote measurements in concrete or composites. They are sensitive to electrical magnetic noises and they degrade in the environment over time. Optical fibers are attractive because they are immune to electromagnetic interference and are sensitive over long distances. The combination of the ability to remotely measure crack occurrence in real time and determine the location and volume of crack damage in the matrix is unique in the field of optic sensors (or any sensors in general). The combination of this with crack repair, rebonding of any detached or broken fibers, and replenishment of liquid core chemicals, when necessary, make this a potentially powerful sensing and repair tool. Work on this research topic of the combination sponsored by the University of Illinois, looks very promising as a rapid innovative advance.

Koehler, Tamara; Brown, Andrew

Understanding how pharmacy technicians and other pharmacy support workforce cadres assist pharmacists in the healthcare system will facilitate developing health systems with the ability to achieve universal health coverage as it is defined in different country contexts. The aim of this paper is to provide an overview of the present global variety in the technician and other pharmacy support workforce cadres considering; their scope, roles, supervision, education and legal framework. A structured online survey instrument was administered globally using the Survey Monkey platform, designed to address the following topic areas: roles, responsibilities, supervision, education and legislation. The survey was circulated to International Pharmaceutical Federation (FIP) member organisations and a variety of global list serves where pharmaceutical services are discussed. 193 entries from 67 countries and territories were included in the final analysis revealing a vast global variety with respect to the pharmacy support workforce. From no pharmacy technicians or other pharmacy support workforce cadres in Japan, through a variety of cadre interactions with pharmacists, to the autonomous practice of pharmacy support workforce cadres in Malawi. From strictly supervised practice with a focus on supply, through autonomous practice for a variety of responsibilities, to independent practice. From complete supervision for all tasks, through geographical varied supervision, to independent practice. From on the job training, through certificate level vocational courses, to 3-4 year diploma programs. From well-regulated and registered, through part regulation with weak implementation, to completely non-regulated contexts. This paper documents wide differences in supervision requirements, education systems and supportive legislation for pharmacy support workforce cadres globally. A more detailed understanding of specific country practice settings is required if the use of pharmacy

Some areas of reliability technique which have been neglected to some extent - maintainability - human reliability - mechanical reliability - repairable systems

Akersten, P.A.

1985-01-01

The present thesis consists of four papers, three of which are of a expositary nature and one more theoretical. The first two papers have a natural coupling to the man-machine interface. The first paper is devoted to the concept of maintainability and the role of man as maintenance technician. The second paper discusses aspects of human reliability, mainly studying man as operator. However, maintenance tasks can be studied in the same manner. The third paper concerns reliability prediction for mechanical components. This is an area of vital importance for the reliability practitioner, who needs realistic and easy-to-use mathematical models for different failure modes. The fourth paper discusses mathematical models for repairable systems, especially the problem of testing whether a constant event intensity model is adequate or not. (author)

Geriatric care mostly consists not in curingthe patient, but supportingthem to the end of their life, giving meaning to care procedures and actions through speech, touch or look and maintaining a connection.The helping relationship is omnipresent and the role of the speech therapist is therefore essential in helping to maintain or re-establish elderly patients' abilityto communicate. However, todaythis role is struggling to define itself between that of the technician-researcher and that of caregiver.

DNA repair

International Nuclear Information System (INIS)

Van Zeeland, A.A.

1984-01-01

In this chapter a series of DNA repair pathways are discussed which are available to the cell to cope with the problem of DNA damaged by chemical or physical agents. In the case of microorganisms our knowledge about the precise mechanism of each DNA repair pathway and the regulation of it has been improved considerably when mutants deficient in these repair mechanisms became available. In the case of mammalian cells in culture, until recently there were very little repair deficient mutants available, because in almost all mammalian cells in culture at least the diploid number of chromosomes is present. Therefore the frequency of repair deficient mutants in such populations is very low. Nevertheless because replica plating techniques are improving some mutants from Chinese hamsters ovary cells and L5178Y mouse lymphoma cells are now available. In the case of human cells, cultures obtained from patients with certain genetic diseases are available. A number of cells appear to be sensitive to some chemical or physical mutagens. These include cells from patients suffering from xeroderma pigmentosum, Ataxia telangiectasia, Fanconi's anemia, Cockayne's syndrome. However, only in the case of xeroderma pigmentosum cells, has the sensitivity to ultraviolet light been clearly correlated with a deficiency in excision repair of pyrimidine dimers. Furthermore the work with strains obtained from biopsies from man is difficult because these cells generally have low cloning efficiencies and also have a limited lifespan in vitro. It is therefore very important that more repair deficient mutants will become available from established cell lines from human or animal origin

Full Text Available Objective: to understand the strategies used by nursing technicians in order to face the occupational suffering in an emergency room. Methods: qualitative study carried out in an emergency room of a high complexity hospital located in the north of Paraná state. Data were collected through semi-structured interviews with 12 nursing technicians. The analysis relied on content analysis procedures. Results: respondents revealed as individual strategies to face suffering: try not to get involved with the patient; separation between professional and personal life; and spirituality/religion as support for coping. The collective strategies described by respondents included: action planning for unexpected events in this unit; creating a supportive environment; and attempt to obtain recognition of headship. Conclusion: individual and collective strategies were used consciously by workers and should be encouraged by managers to face the occupational suffering.

Electric motor predictive and preventive maintenance guide

International Nuclear Information System (INIS)

Oliver, J.A.

1992-07-01

Electric motor performance is vital to the reliable and efficient operation of power plants. The failure of one or more critical motors could cause lost capacity and excessive repair and maintenance cost. However, existing maintenance recommendations proposed by vendors for electric motors have sometimes encouraged many overly conservative maintenance practices. These practices have lead to excessive maintenance activities and costs which have provided no extra margin of operability. EPRI has sponsored RP2814-35 to develop a guide which provides power plants with information and guidance for establishing an effective maintenance program which will aid in preventing unexpected motor failures and assist in planning motor maintenance efforts. The guide includes a technical description which summarizes technical data relative to the four basic types of motors and their components in general use in power plants. The significant causes of motor failures are investigated and described in detail and methods to optimize service life and minimize maintenance cost through appropriate preventive maintenance and conditioning program are presented. This guide provides a foundation for an effective electric motor maintenance program and simplifies the selection of predictive and preventive maintenance tasks. Its use will enable maintenance personnel in nuclear and fossil plants to plan motor repairs during scheduled outages and avoid costly unexpected failures

Full text: As in other countries, life expectancy is increasing in Brazil, and the number of radiological examinations tends to increase. Old equipment and high technology ones cohabit, radiology technicians are not well prepared to conduct practices, images and doses to patients are not optimized. Digital techniques that began to be introduced in the last years are also an important issue, because, as it is possible to modify the image digitally, there is less concern about the choice of equipment parameters that produce the best-image/lowest-dose compromise. Pediatric radiology, CT and fluoroscopy require attention too, as they are of dosimetric interest or because the patient ages imply higher risks or because the techniques deliver higher doses than the conventional ones. In our opinion, the most important role that we can play is educating and forming people to work in this area: training programs and refreshing courses are a way of facing the problem. This way, we are organizing, in a technical cooperation with IAEA, two training courses in quality assurance and radiation protection in radiology, one designed to physicists (60 h), and the radiological technicians (40 h). An important cooperation with a paediatric and a general hospital made it possible to offer courses with 50% practical lessons, performed both in the University and in hospital equipment. Both courses cover a basic Radiation Physics program, radiation protection, image formation and quality control in conventional and digital equipment, and patient dosimetry. Equipment donated by IAEA facilitate the practical QA and dosimetry lessons. The rationale of our project is making it sustainable through the formation of physicists that will go on in the education process of technicians in technical schools. We present the results of the first two courses (physicists and technicians), considering the selection process, the development of the activities, and the assessment both of the students enrolled

Repair kinetics in tissues

International Nuclear Information System (INIS)

Thames, H.D.

1989-01-01

Monoexponential repair kinetics is based on the assumption of a single, dose-independent rate of repair of sublethal injury in the target cells for tissue injury after exposure to ionizing radiation. Descriptions of the available data based on this assumption have proved fairly successful for both acutely responding (skin, lip mucosa, gut) and late-responding (lung, spinal cord) normal tissues. There are indications of biphasic exponential repair in both categories, however. Unfortunately, the data usually lack sufficient resolution to permit unambiguous determination of the repair rates. There are also indications that repair kinetics may depend on the size of the dose. The data are conflicting on this account, however, with suggestions of both faster and slower repair after larger doses. Indeed, experiments that have been explicitly designed to test this hypothesis show either no effect (gut, spinal cord), faster repair after higher doses (lung, kidney), or slower repair after higher doses (skin). Monoexponential repair appears to be a fairly accurate description that provides an approximation to a more complicated picture, the elucidation of whose details will, however, require very careful and extensive experimental study.

2001-01-01

The procedure for repair welding of cracked steam turbine blades made of martensitic stainless steels has been developed using the gas tungsten arc welding process. Weld repair procedures were developed using both ER 316L austenitic and ER 410 martensitic stainless-steel filler wire. The overall development of the repair welding procedure included selection of welding consumables (for austenitic filler metal), optimisation of post-weld heat treatment parameters, selection of suitable method for local pre-heating and post-weld heat treatment (PWHT) of the blades, determination of mechanical properties of weldments in as-welded and PWHT conditions, and microsturctural examination. After various trials using different procedures, the procedure of local PWHT (and preheating when using martensitic stainless-steel filler wire) using electrical resistance heating on the top surface of the weldment and monitoring the temperature by placing a thermocouple at the bottom of the weld was found to give the most satisfactory results. These procedures have been developed and/or applied for repair welding of cracked blades in steam turbines

A geometric process repair model for a repairable cold standby system with priority in use and repair

International Nuclear Information System (INIS)

Zhang Yuanlin; Wang Guanjun

2009-01-01

In this paper, a deteriorating cold standby repairable system consisting of two dissimilar components and one repairman is studied. For each component, assume that the successive working times form a decreasing geometric process while the consecutive repair times constitute an increasing geometric process, and component 1 has priority in use and repair. Under these assumptions, we consider a replacement policy N based on the number of repairs of component 1 under which the system is replaced when the number of repairs of component 1 reaches N. Our problem is to determine an optimal policy N* such that the average cost rate (i.e. the long-run average cost per unit time) of the system is minimized. The explicit equation of the average cost rate of the system is derived and the corresponding optimal replacement policy N* can be determined analytically or numerically. Finally, a numerical example with Weibull distribution is given to illustrate some theoretical results in this paper.

Phenomenology of an inducible mutagenic DNA repair pathway in Escherichia coli: SOS repair hypothesis

International Nuclear Information System (INIS)

Radman, M.

1974-01-01

A hypothesis is proposed according to which E. coli possesses an inducible DNA repair system. This hypothetical repair, which we call SOS repair, is manifested only following damage to DNA, and requires de novo protein synthesis. SOS repair in E. coli requires some known genetic elements: recA + , lex + and probably zab + . Mutagenesis by ultraviolet light is observed only under conditions of functional SOS repair: we therefore suspect that this is a mutation-prone repair. A number of phenomena and experiments is reviewed which at this point can best be interpreted in terms of an inducible mutagenic DNA repair system. Two recently discovered phenomena support the proposed hypothesis: existence of a mutant (tif) which, after a shift to elevated temperature, mimicks the effect of uv irradiation in regard to repair of phage lambda and uv mutagenesis, apparent activation of SOS repair by introduction into the recipient cell of damaged plasmid or Hfr DNA. Several specific predictions based on SOS repair hypothesis are presented in order to stimulate further experimental tests. (U.S.)

Endogenous electric fields are instructive during embryogenesis by acting to direct cell migration, and postnatally, they can promote axonal growth after injury (McCaig 1991, Al-Majed 2000). However, the mechanisms for these changes are not well understood. Application of an appropriate electrical stimulus may increase the rate and success of nerve repair by directly promoting axonal growth. Previously, DC electrical stimulation at 50 mV/mm (1 mA, 8 h duration) was shown to promote neurite ou...

Traumatic Tricuspid Insufficiency Requiring Valve Repair in an Acute Setting.

Science.gov (United States)

Enomoto, Yoshinori; Sudo, Yoshio; Sueta, Tomonori

2015-01-01

Tricuspid insufficiency due to penetrating cardiac trauma is rare. Patients with tricuspid insufficiency due to trauma can tolerate this abnormality for months or even years. We report a case of a 66-year-old female with penetrating cardiac trauma on the right side of her heart that required tricuspid valve repair in an acute setting. She sustained cut and stab wounds on her bilateral forearms and in the neck and epigastric region. She had cardiac tamponade and developed pulseless electrical activity, which required emergency surgery. The right ventricle and superior vena cava were dissected approximately 5 cm and 2 cm, respectively. After these wounds had been repaired, the patient's inability to wean from cardiopulmonary bypass suggested rightsided heart failure; transesophageal echocardiography revealed tricuspid insufficiency. Right atriotomy was performed, and a detailed examination revealed that the tricuspid valve septal leaflet was split in two. There was also an atrial septal injury that created a connection with the left atrium; these injuries were not detected from the right ventricular wound. After repair, weaning from cardiopulmonary bypass with mild tricuspid insufficiency was achieved, and she recovered uneventfully. This case emphasized the importance of thoroughly investigating intracardiac injury and transesophageal echocardiography.

Analysis for a two-dissimilar-component cold standby repairable system with repair priority

International Nuclear Information System (INIS)

Leung, Kit Nam Francis; Zhang Yuanlin; Lai, Kin Keung

2011-01-01

In this paper, a cold standby repairable system consisting of two dissimilar components and one repairman is studied. Assume that working time distributions and repair time distributions of the two components are both exponential, and Component 1 has repair priority when both components are broken down. After repair, Component 1 follows a geometric process repair while Component 2 obeys a perfect repair. Under these assumptions, using the perfect repair model, the geometric process repair model and the supplementary variable technique, we not only study some important reliability indices, but also consider a replacement policy T, under which the system is replaced when the working age of Component 1 reaches T. Our problem is to determine an optimal policy T* such that the long-run average loss per unit time (i.e. average loss rate) of the system is minimized. The explicit expression for the average loss rate of the system is derived, and the corresponding optimal replacement policy T* can be found numerically. Finally, a numerical example for replacement policy T is given to illustrate some theoretical results and the model's applicability. - Highlights: → A two-dissimilar-component cold standby system with repair priority is formulated. → The successive up/repair times of Component 1 form a decreasing/increasing geometric process. → Not only some reliability indices but also a replacement policy are studied.

Malaria is still one of the most important public health problems worldwide. The diagnosis of this disease is still mainly based on thick blood films.  To evaluate the knowledge about malaria diagnosis of the technicians of the public health network in Luanda, Angola, by means of a survey.  This survey was carried out in three phases. In the first one, open interviews were done to technicians related with the different procedures for malaria diagnosis. In the second one, a preliminary questionnaire was prepared and evaluated. In the third phase, a definitive questionnaire was applied to 120 technicians from Luanda between April and July, 2013. The proportions of correct and incorrect answers were compared for every question of the survey.  Significantly higher proportions of incorrect answers (p<0.05) were found in the questions related to clinical manifestations, 68/52 (p<0.05), species of Plasmodium according to geographical areas, 76/44 (p<0.05), the type of granulations according to species, 96/24 (p<0.01), the class of microscope magnifying glasses used to observe the thick smear, 105/15 (p<0.01), the thick smear report, 76/44 (p<0.01), the time and preparation of different stain solutions, 81/39 (p<0.01), and the number of parasites counted per 200 leukocytes, 96/24 (p<0.01).  Various failures for the microscopic diagnosis of malaria were observed amongst the evaluated technicians. These results will be useful as a baseline study before applying an educational intervention aimed to improve the quality of malaria diagnosis in Luanda's laboratory network.

Technician support for operation and maintenance of large fusion experiments: the tandem mirror experiment upgrade (TMX-U) approach

International Nuclear Information System (INIS)

Mattson, G.E.

1983-01-01

As experiments continue to grow in size and complexity, a few technicians will no longer be able to maintain and operate the complete experiment. Specialization is becoming the norm. Subsystems are becoming very large and complex, requiring a great deal of experience and training for technicians to become qualified maintenance/operation personnel. Formal in-house and off-site programs supplement on-the-job training to fulfill the qualification criteria. This paper presents the Tandem Mirror Experiment-Upgrade (TMX-U) approach to manpower staffing, some problems encountered, possible improvements, and safety considerations for the successful operation of a large experimental facility

Our primary objective is to elucidate the molecular events in human cells when cellular macromolecules such as DNA are damaged by radiation or chemical agents. We study and characterize (i) the sequence of DNA repair events, (ii) the various modalities of repair, (iii) the genetic inhibition of repair due to mutation, (iv) the physiological inhibition of repair due to mutation, (v) the physiological inhibition of repair due to biochemical inhibitors, and (vi) the genetic basis of repair. Our ultimate goals are to (i) isolate and analyze the repair component of the mutagenic and/or carcinogenic event in human cells, and (ii) elucidate the magnitude and significance of this repair component as it impinges on the practical problems of human irradiation or exposure to actual or potential chemical mutagens and carcinogens. The significance of these studies lies in (i) the ubiquitousness of repair (most organisms, including man, have several complex repair systems), (ii) the belief that mutagenic and carcinogenic events may arise only from residual (nonrepaired) lesions or that error-prone repair systems may be the major induction mechanisms of the mutagenic or carcinogenic event, and (iii) the clear association of repair defects and highly carcinogenic disease states in man [xeroderma pigmentosum (XP)

Flexor tendon repair: a comparative study between a knotless barbed suture repair and a traditional four-strand monofilament suture repair.

LENUS (Irish Health Repository)

Joyce, C W

2014-01-01

We compared the tensile strength of a novel knotless barbed suture method with a traditional four-strand Adelaide technique for flexor tendon repairs. Forty fresh porcine flexor tendons were transected and randomly assigned to one of the repair groups before repair. Biomechanical testing demonstrated that the tensile strengths between both tendon groups were very similar. However, less force was required to create a 2 mm gap in the four-strand repair method compared with the knotless barbed technique. There was a significant reduction in the cross-sectional area in the barbed suture group after repair compared with the Adelaide group. This would create better gliding within the pulley system in vivo and could decrease gapping and tendon rupture.

In vitro effects of direct current electric fields on adipose-derived stromal cells.

Science.gov (United States)

Hammerick, Kyle E; Longaker, Michael T; Prinz, Fritz B

2010-06-18

Endogenous electric fields play an important role in embryogenesis, regeneration, and wound repair and previous studies have shown that many populations of cells, leukocytes, fibroblasts, epithelial cells, and endothelial cells, exhibit directed migration in response to electric fields. As regenerative therapies continue to explore ways to control mesenchymal progenitor cells to recreate desirable tissues, it is increasingly necessary to characterize the vast nature of biological responses imposed by physical phenomena. Murine adipose-derived stromal cells (mASCs) migrated toward the cathode in direct current (DC) fields of physiologic strength and show a dose dependence of migration rate to stronger fields. Electric fields also caused mASCs to orient perpendicularly to the field vector and elicited a transient increase in cytosolic calcium. Additionally, their galvanotactic response appears to share classic chemotactic signaling pathways that are involved in the migration of other cell types. Galvanotaxis is one predominant result of electric fields on mASCs and it may be exploited to engineer adult stem cell concentrations and locations within implanted grafts or toward sites of wound repair.

Student reactions to problem-based learning in photonics technician education

Science.gov (United States)

Massa, Nicholas M.; Donnelly, Judith; Hanes, Fenna

2014-07-01

Problem-based learning (PBL) is an instructional approach in which students learn problem-solving and teamwork skills by collaboratively solving complex real-world problems. Research shows that PBL improves student knowledge and retention, motivation, problem-solving skills, and the ability to skillfully apply knowledge in new and novel situations. One of the challenges faced by students accustomed to traditional didactic methods, however, is acclimating to the PBL process in which problem parameters are often ill-defined and ambiguous, often leading to frustration and disengagement with the learning process. To address this problem, the New England Board of Higher Education (NEBHE), funded by the National Science Foundation Advanced Technological Education (NSF-ATE) program, has created and field tested a comprehensive series of industry-based multimedia PBL "Challenges" designed to scaffold the development of students' problem solving and critical thinking skills. In this paper, we present the results of a pilot study conducted to examine student reactions to the PBL Challenges in photonics technician education. During the fall 2012 semester, students (n=12) in two associate degree level photonics courses engaged in PBL using the PBL Challenges. Qualitative and quantitative methods were used to assess student motivation, self-efficacy, critical thinking, metacognitive self-regulation, and peer learning using selected scales from the Motivated Strategies for Learning Questionnaire (MSLQ). Results showed positive gains in all variables. Follow-up focus group interviews yielded positive themes supporting the effectiveness of PBL in developing the knowledge, skills and attitudes of photonics technicians.

PWR fuel inspection and repair technology development in the Republic of Korea

International Nuclear Information System (INIS)

Park, J.Y.

1998-01-01

As of September 1997, 10 PWRs and 2 PHWRs generate 10,320MW electricity in Korea. And another 8 PWRs and 2 PHWRs will be constructed by 2006. These will need about 400 MTU of PWR fuels and 400 MTU of PHWR fuels. To improve average burnup, thermal power, fuel usability and plant safety, better poolside fuel service technologies are strongly recommended as well as the fuel design and fabrication technology improvements. During the last twenty years of nuclear power plant operation in Korea, more than 4,000 fuel assemblies has been used. At the site, continuous coolant activity measurement, pool-side visual inspection and ultrasonic tests have been performed. Some of the fuels are damaged or failed for various reasons. Some of the defected fuels were examined in hot cell to investigate the cause of failure. Even though 30 PWR fuel assemblies were repaired by foreign engineers, fuel inspection and repair technologies are not established yet. Various kind of design for the fuel make the inspection, repair and reconstitution equipment more complex. As a result, recently, a plant to obtain overall technology for poolside fuel inspection, failed fuel repair and reconstitution through R and D activities are set forth. (author)

Schindler, Birgit Karin; Koslitz, Stephan; Weiss, Tobias; Broding, Horst Christoph; Brüning, Thomas; Bünger, Jürgen

2014-01-01

Hydraulic fluids and turbine oils contain organophosphates like tricresyl phosphate isomers, triphenyl phosphate and tributyl phosphate from very small up to high percentages. The aim of this pilot study was to determine if aircraft maintenance technicians are exposed to relevant amounts of organophosphates. Dialkyl and diaryl phosphate metabolites of seven organophosphates were quantified in pre- and post-shift spot urine samples of technicians (N=5) by GC-MS/MS after solid phase extraction and derivatization. Pre- and post shift values of tributyl phosphate metabolites (dibutyl phosphate (DBP): median pre-shift: 12.5 μg/L, post-shift: 23.5 μg/L) and triphenyl phosphate metabolites (diphenyl phosphate (DPP): median pre-shift: 2.9 μg/L, post-shift: 3.5 μg/L) were statistically higher than in a control group from the general population (median DBP: <0.25 μg/L, median DPP: 0.5 μg/L). No tricresyl phosphate metabolites were detected. The aircraft maintenance technicians were occupationally exposed to tributyl and triphenyl phosphate but not to tricresyl phosphate, tri-(2-chloroethyl)- and tri-(2-chloropropyl)-phosphate. Further studies are necessary to collect information on sources, routes of uptake and varying exposures during different work tasks, evaluate possible health effects and to set up appropriate protective measures.

Accelerated electricity conservation in Juneau, Alaska: A study of household activities that reduced demand 25%

International Nuclear Information System (INIS)

Leighty, Wayne; Meier, Alan

2011-01-01

An avalanche destroyed the main hydroelectric transmission line to Juneau, Alaska in April, 2008. Diesel-generated electricity was substituted, causing electricity prices to increase 500% for 45 days. Electricity demand fell by 25% during the supply disruption. Most of the reduction occurred before the higher rates were implemented. Some conservation - about 8% of historic consumption - persisted after the transmission line was repaired and prices returned to normal. Consumers reduced energy use through a combination of new habits and technical improvements. A survey of residential consumers indicated that the average household undertook 10 conservation actions, with major changes in lighting, space heating, fuel switching, and water and appliance use. We propose a method for prioritizing conservation actions for promotion according to their impact in electricity savings (as a function of popularity, effectiveness, and persistence) and a dynamic framework for electricity use before, during, and after a supply disruption (i.e., both the magnitude and rates of change in electricity conservation). - Research highlights: → An electricity supply disruption caused prices to increase 500% for 45 days. → Electricity conservation of 25% occurred in a matter of days. → Electricity conservation of 8% persisted after the supply disruption was repaired. → Conservation occurred through behavior change and technology adoption. → The disruption induced consumers to try new behaviors that became new habits.

Advances in arthroscopic techniques for rotator cuff repair have made the mini-open approach less popular. However, the mini-open approach remains an important technique for repair for many surgeons. The aims of this study were to compare the integrity of the repair, the function of the shoulder and satisfaction post-operatively using these two techniques in patients aged > 50 years. We identified 22 patients treated with mini-open and 128 patients treated with arthroscopic rotator cuff repair of July 2007 and June 2011. The mean follow-up was two years (1 to 5). Outcome was assessed using the American Shoulder and Elbow Surgeons (ASES) and Simple Shoulder Test (SST) scores, and satisfaction. The integrity of the repair was assessed using ultrasonography. A power analysis ensured sufficient enrolment. There was no statistically significant difference between the age, function, satisfaction, or pain scores (p > 0.05) of the two groups. The integrity of the repair and the mean SST scores were significantly better in the mini-open group (91% of mini-open repairs were intact versus 60% of arthroscopic repairs, p = 0.023; mean SST score 10.9 (standard deviation (sd) 1.3) in the mini-open group; 8.9 (sd 3.5) in arthroscopic group; p = 0.003). The ASES scores were also higher in the mini-open group (mean ASES score 91.0 (sd 10.5) in mini-open group; mean 82.70 (sd 19.8) in the arthroscopic group; p = 0.048). The integrity of the repair and function of the shoulder were better after a mini-open repair than after arthroscopic repair of a rotator cuff tear in these patients. The functional difference did not translate into a difference in satisfaction. Mini-open rotator cuff repair remains a useful technique despite advances in arthroscopy.

Researchers and technicians have been giving a lot of attention to the issue of discount factor in planning in the electric sector. In this paper we review the most important points under consideration, attempting to broaden the discussion and stimulate the creativity of the technicians involved with the sector. There appears to be an emerging consensus that the discount factor to be used must consider the capital costs associated with the main financial sources utilized. The traditional factor of 10% per year must be re-evaluated and augmented, in order to best reflect long range economical and financial conditions. The paper emphasizes the importance of the discount factor to several decisions made within the sector, including energy conservation. Because of the relevance of the topic to Brazil future, we strongly suggest the utilization of sensitivity analysis techniques. (author).

IntroductionPreservation of venous access in children is a major concern in pediatric interventional radiology. If a peripherally inserted central catheter (PICC) breaks, there are two options: repair the line with a repair kit or exchange the line over a wire in the interventional suite. The purpose of this study is to assess the outcome of PICC repairs in children and to compare these with the outcomes of PICC exchange.Materials and MethodsThis is a single-center, retrospective study of central line-associated bloodstream infection (CLABSI) following management of externally broken PICCs (2010–2014). The occurrence of CLABSI within 30 days after repair (Group A) or exchange (Group B) of a line was analyzed, as well as PICCs exchanged following an initial and failed repair.ResultsA total of 235 PICC breaks were included in the study, of which 161 were repaired, and 116 of whom were successful (68%, Group A). No repair was performed in 74 PICCs—55/74 of these were exchanged over a wire (74%, Group B), and 19/74 lines were removed. The 30 days post-repair CLABSI rate (Group A) was 2.0 infections per 1000 catheter days, and the calculated risk was 4.3%. In comparison the 30 days post-exchange CLABSI rate (Group B) was 4.0 per 1000 catheter days and the calculated risk 10.9%. This difference was significant when adjusted for antibiotic use (OR 3.87; 95% CI 1.07–14.0, p = 0.039).ConclusionThe results of this study support repairing a broken PICC instead of removing or replacing the line.

Highlights: ► Residual stress in the repair weld of a stainless steel clad plate is investigated. ► The effect of repair length on residual stress has been studied. ► Large tensile residual stress is generated in the repair weld and heat affected zone. ► With the increase of repair length, transverse stress is decreased. ► Repair length has little effect on longitudinal stress. - Abstract: A 3-D sequential coupling finite element simulation is performed to investigate the temperature field and residual stress in the repair weld of a stainless steel clad plate. The effect of repair length on residual stress has been studied, aiming to provide a reference for repairing the cracked clad plate. The results show that large tensile residual stresses are generated in the repair weld and heat affected zone (HAZ), and then decrease gradually away from the weld and HAZ. The residual stresses through thickness in the clad layer are relative uniform, while they are non-uniform in the base metal. A discontinuous stress distribution is generated across the interface between weld metal and base metal. The repair length has a great effect on transverse stress. With the increase of repair length, the transverse stress is decreased. When the repair length is increased to 14 cm, the peak of transverse stress has been decreased below yield strength, and the transverse stress in the weld and HAZ has also been greatly decreased. But the repair length has little effect on longitudinal stress.

Medication reconciliation reduces potential medication discrepancies and adverse drug events. The role of pharmacy technicians in obtaining best possible medication histories (BPMHs) and performing reconciliation at the admission and transfer interfaces of care for pediatric patients has not been described. To compare the completeness and accuracy of BPMHs and reconciliation conducted by a pharmacy technician (pilot study) and by nurses and/or pharmacists (baseline). The severity of identified unintentional discrepancies was rated to determine their clinical importance. This prospective cohort comparison study involved patients up to 18 years of age admitted to and/or transferred between the Cardiology ward and the Cardiac Critical Care Unit of a pediatric tertiary care teaching hospital. A pharmacy resident conducted two 3-week audits: the first to assess the completeness and accuracy of BPMHs and reconciliation performed by nurses and/or pharmacists and the second to assess the completeness and accuracy of BPMHs and reconciliation performed by a pharmacy technician. The total number of patients was 38 in the baseline phase and 46 in the pilot period. There were no statistically significant differences between the baseline and pilot audits in terms of completion of BPMH (82% [28/34] versus 78% [21/27], p = 0.75) or completion of reconciliation (70% [23/33] versus 75% [15/20], p = 0.76) within 24 h of admission. Completeness of transfer reconciliation was significantly higher during the pilot study than at baseline (91% [31/34] versus 61% [11/18], p = 0.022). No significant differences between the baseline and pilot audits were found in the proportions of patients with at least one BPMH discrepancy (38% [13/34] versus 22% [6/27], p = 0.27), at least one unintentional discrepancy upon admission (21% [7/33] versus 10% [2/20], p = 0.46), or at least one unintentional discrepancy at the transfer interface (6% [1/18] versus 3% [1/34], p = 0.58).

An electrical safety in health care area is necessary to protect patients and staff from potential electrical hazards.Functional, accurate and safe clinical equipment is an essential requirement in the provision of health services. Well-maintained equipment will give clinicians greater confidence in the reliability of its performance and contribute to a high standard of client care. Clinical equipment, like all health services, requires annual or periodic servicing of medical equipment. In addition to planned servicing and preventative maintenance, there may be the unexpected failure of medical (and other) equipment, necessitating repair. In general, clinical equipment that has an electrical power source and has direct contact with the client must be serviced as a first priority. In this presentation, a review of the main concepts related to the electrical safety in health area,theinternational standard, the distribution of electric power in hospital and protection against shockwill be introduced. Protection system in hospital will be presented in its two ways: inpower distribution in hospitaland inbiomedical equipment design,finally the optimum maintenance technology and safety tests in health care areawill presented also.

DNA repair deficiency in neurodegeneration

2011-01-01

Deficiency in repair of nuclear and mitochondrial DNA damage has been linked to several neurodegenerative disorders. Many recent experimental results indicate that the post-mitotic neurons are particularly prone to accumulation of unrepaired DNA lesions potentially leading to progressive...... neurodegeneration. Nucleotide excision repair is the cellular pathway responsible for removing helix-distorting DNA damage and deficiency in such repair is found in a number of diseases with neurodegenerative phenotypes, including Xeroderma Pigmentosum and Cockayne syndrome. The main pathway for repairing oxidative...... base lesions is base excision repair, and such repair is crucial for neurons given their high rates of oxygen metabolism. Mismatch repair corrects base mispairs generated during replication and evidence indicates that oxidative DNA damage can cause this pathway to expand trinucleotide repeats, thereby...

Full Text Available The most important performance for repair materials is adhesion to the substrate. The authors experimentally find out that high modulus fine aggregates in repair material enhance strength of it as well as the strength of the interface repaired with it, compared to the ordinary repair without fine aggregates. This paper elaborates the mechanisms for that with fractographic observation and FEM analysis based on the results of experiment. Also the authors discuss the ways for enhancing the strength and ductility of the repaired mortar

With the ever increasing environmental exposure to man-made electromagnetic fields (EMFs), public concern regarding the potential health hazards of exposure to electric and magnetic fields at extremely low frequencies (ELF) has also increased. This paper examined the ELF fields at a 150/20 kV outdoor electric power substation in Xanthi, Greece. Basic data regarding this substation was provided along with previous relevant research studies. The reference levels for safe general public and occupational exposure according to the International Commission on Non-Ionizing Radiation Protection (ICNIRP) was also presented. The instruments used to take the measurements were described and indicative results of the EMFs measurements in the substation were provided. In general, the measured magnetic flux density values were far below the reference level for safe public and occupational exposure. No significant differentiation was noted in these values in relation to body height. However, the levels were found to be in violation in two positions, near the capacitor banks. It was emphasized that these values greatly decreased with distance, and the positions where these high values were measured were not occupied by technicians when the capacitors were under voltage. In addition, it was emphasized that the measured magnetic flux density values were very small in the supervision room, where the supervisor of the substation works and in the ring zone where the public has access. All the measured electric field strength values were below the reference level for safe public and occupational exposure. It was concluded that the measured field values are within recognized guidelines and pose no danger for public or working personnel. 19 refs., 1 tab., 4 figs.

Infrared Thermography (IrT) has been shown to be capable of detecting and monitoring service induced damage of repair composite structures. Full-field imaging, along with portability are the primary benefits of the thermographic technique. On-line lock-in thermography has been reported to successfully monitor damage propagation or/and stress concentration in composite coupons, as mechanical stresses in structures induce heat concentration phenomena around flaws. During mechanical fatigue, cyclic loading plays the role of the heating source and this allows for critical and subcritical damage identification and monitoring using thermography. The Electrical Potential Change Technique (EPCT) is a new method for damage identification and monitoring during loading. The measurement of electrical potential changes at specific points of Carbon Fiber Reinforced Polymers (CFRPs) under load are reported to enable the monitoring of strain or/and damage accumulation. Along with the aforementioned techniques Finally, Acoustic Emission (AE) method is well known to provide information about the location and type of damage. Damage accumulation due to cyclic loading imposes differentiation of certain parameters of AE like duration and energy. Within the scope of this study, infrared thermography is employed along with AE and EPCT methods in order to assess the integrity of bonded repair patches on composite substrates and to monitor critical and subcritical damage induced by the mechanical loading. The combined methodologies were effective in identifying damage initiation and propagation of bonded composite repairs.

Neuronal DNA repair remains one of the most exciting areas for investigation, particularly as a means to compare the DNA repair response in mitotic (cancer) vs. post-mitotic (neuronal) cells. In addition, the role of DNA repair in neuronal cell survival and response to aging and environmental insults is of particular interest. DNA damage caused by reactive oxygen species (ROS) such as generated by mitochondrial respiration includes altered bases, abasic sites, and single- and double-strand breaks which can be prevented by the DNA base excision repair (BER) pathway. Oxidative stress accumulates in the DNA of the human brain over time especially in the mitochondrial DNA (mtDNA) and is proposed to play a critical role in aging and in the pathogenesis of several neurological disorders including Parkinson's disease, ALS, and Alzheimer's diseases. Because DNA damage accumulates in the mtDNA more than nuclear DNA, there is increased interest in DNA repair pathways and the consequence of DNA damage in the mitochondria of neurons. The type of damage that is most likely to occur in neuronal cells is oxidative DNA damage which is primarily removed by the BER pathway. Following the notion that the bulk of neuronal DNA damage is acquired by oxidative DNA damage and ROS, the BER pathway is a likely area of focus for neuronal studies of DNA repair. BER variations in brain aging and pathology in various brain regions and tissues are presented. Therefore, the BER pathway is discussed in greater detail in this review than other repair pathways. Other repair pathways including direct reversal, nucleotide excision repair (NER), mismatch repair (MMR), homologous recombination and non-homologous end joining are also discussed. Finally, there is a growing interest in the role that DNA repair pathways play in the clinical arena as they relate to the neurotoxicity and neuropathy associated with cancer treatments. Among the numerous side effects of cancer treatments, major clinical effects

2005-06-01

Full Text Available This study prepared a basic framework for the development and improvement of Korean Dental Technicians' Licensing Examination, based on actual test questions. A peer review was conducted to ensure relevance to current practices in dental technology. For the statistical analysis, 1000 dental laboratory technicians were selected; specialists in dental laboratory technology (laboratory owners, educators, etc. were involved in creating valid and reliable questions. Results indicated that examination subjects should be divided into three categories: basic dental laboratory theory, dental laboratory specialties, and a practical examination. To ensure relevance to current practice, there should be less emphasis on basic dental laboratory theory, including health-related laws, and more emphasis on dental laboratory specialties. Introduction to dental anatomy should be separated from oral anatomy and tooth morphology; and fixed prosthodontics should be separated from crown and bridge technology and dental ceramics technology. Removable orthodontic appliance technology should be renamed 'orthodontic laboratory technology'. There should be less questions related to health related law, oral anatomy, dental hygiene, dental materials science and inlay, while the distribution ratio of questions related to tooth morphology should be maintained. There should be a decrease in the distribution ratio of questions related to crown and bridge technology, dental ceramics technology, complete dentures and removable partial dentures technology, and orthodontic laboratory technology. In the practical examination, the current multiple choice test should be replaced with tooth carving using wax or plaster. In dental laboratory specialties, subjects related to contemporary dental laboratory technology should be included in the test items.

USING THE OUTSOURCING MECHANISM TO INCREASE THE EFFICIENCY OF REPAIR AND MAINTENANCE IN METALLURGICAL ENTERPRISES

2017-01-01

Full Text Available Abstract. Objectives The aim of the work is to study the outsourcing mechanism from the point of view of increasing the efficiency of repair and maintenance at a metallurgical enterprise. Method Analysis of the experience of using outsourcing of repair services at domestic and foreign metallurgical enterprises was carried out. Analysis of the experience of the withdrawal from enterprise repair services into a separate outsourcing company has shown that the main advantages of this method of organising repair activities are an increase in the transparency of the costs of repairs and maintenance, and hence their reduction, as well as a reduction in the amount of equipment downtime. The main characteristics of outsourcing were revealed, substantiating its expediency. The restructuring of the repair system provides a step-by-step transition from decentralised to centralised structures of technical, mechanical, power and electrical repair services of enterprises, from the principle of "self-service" to the principle of "proprietary service" by isolating the subdivisions of the repair system from the structure of enterprises and creating competing members of the repair services market. Put another way, this is typified by moving away from the status of auxiliary production to a selfdependent activity. The stages of outsourcing the repair services of the enterprise are considered and possible problems that may arise in the course of the work of a working group are established to determine the suitability of outsourcing and to resolve the numerous issues arising from the transfer of repair functions. Results The findings of the research include approaches developed for overcoming risky situations: providing guarantees from the customer and the contractor and indicating them in the contract, increasing the motivation of the outsourcing company through a key performance indicator that should increase the interest of the performer in providing quality

This paper analyzes a system subject to repairable and non-repairable failures. Non-repairable failures lead to replacement of the system. Repairable failures, first lead to repair but they lead to replacement after a fixed number of repairs. Operating and repair times follow phase type distributions (PH-distributions) and the pattern of the operating times is modelled by a geometric process. In this context, the problem is to find the optimal number of repairs, which maximizes the long-run average reward per unit time. To this end, the optimal number is determined and it is obtained by efficient numerical procedures

A new incomplete-repair model based on a ''reciprocal-time'' pattern of sublethal damage repair

International Nuclear Information System (INIS)

Dale, R.G.; Fowler, J.F.

1999-01-01

A radiobiological model for closely spaced non-instantaneous radiation fractions is presented, based on the premise that the time process of sublethal damage (SLD) repair is 'reciprocal-time' (second order), rather than exponential (first order), in form. The initial clinical implications of such an incomplete-repair model are assessed. A previously derived linear-quadratic-based model was revised to take account of the possibility that SLD may repair with time such that the fraction of an element of initial damage remaining at time t is given as 1/(1+zt), where z is an appropriate rate constant; z is the reciprocal of the first half-time (τ) of repair. The general equation so derived for incomplete repair is applicable to all types of radiotherapy delivered at high, low and medium dose-rate in fractions delivered at regular time intervals. The model allows both the fraction duration and interfraction intervals to vary between zero and infinity. For any given value of z, reciprocal repair is associated with an apparent 'slowing-down' in the SLD repair rate as treatment proceeds. The instantaneous repair rates are not directly governed by total dose or dose per fraction, but are influenced by the treatment duration and individual fraction duration. Instantaneous repair rates of SLD appear to be slower towards the end of a continuous treatment, and are also slower following 'long' fractions than they are following 'short' fractions. The new model, with its single repair-rate parameter, is shown to be capable of providing a degree of quantitative explanation for some enigmas that have been encountered in clinical studies. A single-component reciprocal repair process provides an alternative explanation for the apparent existence of a range of repair rates in human tissues, and which have hitherto been explained by postulating the existence of a multi-exponential repair process. The build-up of SLD over extended treatments is greater than would be inferred using a

This pilot study aimed to investigate the use of personal protective equipment (PPE) and compliance to the code of conduct (rules defined in institutional, governmental and professional guidelines) among laboratory technicians in Croatian medical laboratories. In addition, we explored the differences in compliance between participants of different age groups, laboratory ownership and accreditation status. An anonymous and voluntary survey with 15 questions was conducted among Croatian medical laboratory technicians (N=217). The questions were divided into two groups: demographic characteristics and the use of PPE. The questions of the second part were graded according to the Likert scale (1-4) and an overall score, shown as median and range (min-max), was calculated for each participant. Differences between the overall scores were tested for each group of participants. The majority of participants always wear protective clothes at work, 38.7% of them always wear gloves in daily routine, more than 30.0% consume food and almost half of them drink beverages at workplace. A significantly lower overall score was found for participants working in public compared to private laboratories (36 (16-40) vs. 40 (31-40), Plaboratory accreditation status (P=0.081). A considerable percentage of laboratory technicians in Croatian medical laboratories do not comply with safety measures. Lack of compliance is observed in all personnel regardless laboratory accreditation and participants' age. However, those working in private laboratories adhere more to the code of conduct.

Complex networks under dynamic repair model

Chaoqi, Fu; Ying, Wang; Kun, Zhao; Yangjun, Gao

2018-01-01

Invulnerability is not the only factor of importance when considering complex networks' security. It is also critical to have an effective and reasonable repair strategy. Existing research on network repair is confined to the static model. The dynamic model makes better use of the redundant capacity of repaired nodes and repairs the damaged network more efficiently than the static model; however, the dynamic repair model is complex and polytropic. In this paper, we construct a dynamic repair model and systematically describe the energy-transfer relationships between nodes in the repair process of the failure network. Nodes are divided into three types, corresponding to three structures. We find that the strong coupling structure is responsible for secondary failure of the repaired nodes and propose an algorithm that can select the most suitable targets (nodes or links) to repair the failure network with minimal cost. Two types of repair strategies are identified, with different effects under the two energy-transfer rules. The research results enable a more flexible approach to network repair.

Harnessing the potential of biomaterials for brain repair after stroke

Science.gov (United States)

Tuladhar, Anup; Payne, Samantha L.; Shoichet, Molly S.

2018-03-01

Stroke is a devastating disease for which no clinical treatment exists to regenerate lost tissue. Strategies for brain repair in animal models of stroke include the delivery of drug or cell-based therapeutics; however, the complex anatomy and functional organization of the brain presents many challenges. Biomaterials may alleviate some of these challenges by providing a scaffold, localizing the therapy to the site of action, and/or modulating cues to brain cells. Here, the challenges associated with delivery of therapeutics to the brain and the biomaterial strategies used to overcome these challenges are described. For example, innovative hydrogel delivery systems have been designed to provide sustained trophic factor delivery for endogenous repair and to support transplanted cell survival and integration. Novel treatments, such as electrical stimulation of transplanted cells and the delivery of factors for the direct reprogramming of astrocytes into neurons, may be further enhanced by biomaterial delivery systems. Ultimately, improved clinical translation will be achieved by combining clinically relevant therapies with biomaterials strategies.

Electrical Stimulation to Enhance Axon Regeneration After Peripheral Nerve Injuries in Animal Models and Humans.

Science.gov (United States)

Gordon, Tessa

2016-04-01

Injured peripheral nerves regenerate their lost axons but functional recovery in humans is frequently disappointing. This is so particularly when injuries require regeneration over long distances and/or over long time periods. Fat replacement of chronically denervated muscles, a commonly accepted explanation, does not account for poor functional recovery. Rather, the basis for the poor nerve regeneration is the transient expression of growth-associated genes that accounts for declining regenerative capacity of neurons and the regenerative support of Schwann cells over time. Brief low-frequency electrical stimulation accelerates motor and sensory axon outgrowth across injury sites that, even after delayed surgical repair of injured nerves in animal models and patients, enhances nerve regeneration and target reinnervation. The stimulation elevates neuronal cyclic adenosine monophosphate and, in turn, the expression of neurotrophic factors and other growth-associated genes, including cytoskeletal proteins. Electrical stimulation of denervated muscles immediately after nerve transection and surgical repair also accelerates muscle reinnervation but, at this time, how the daily requirement of long-duration electrical pulses can be delivered to muscles remains a practical issue prior to translation to patients. Finally, the technique of inserting autologous nerve grafts that bridge between a donor nerve and an adjacent recipient denervated nerve stump significantly improves nerve regeneration after delayed nerve repair, the donor nerves sustaining the capacity of the denervated Schwann cells to support nerve regeneration. These reviewed methods to promote nerve regeneration and, in turn, to enhance functional recovery after nerve injury and surgical repair are sufficiently promising for early translation to the clinic.

Ryan, Stephen

2010-01-01

Perineal hernias are infrequent complications following abdominoperineal operations. Various approaches have been described for repair of perineal hernias including open transabdominal, transperineal or combined abdominoperineal repairs. The use of laparoscopic transabdominal repair of perineal hernias is not well-described. We present a case report demonstrating the benefits of laparoscopic repair of perineal hernia following previous laparoscopic abdominoperineal resection (APR) using a nonabsorbable mesh to repair the defect. We have demonstrated that the use of laparoscopy with repair of the pelvic floor defect using a non absorbable synthetic mesh offers an excellent alternative with many potential advantages over open transabdominal and transperineal repairs.

Transfer of Chinese hamster DNA repair gene(s) into repair-deficient human cells (Xeroderma pigmentosum)

Transfer of repair genes by DNA transfection into repair-deficient Xeroderma pigmentosum (XP) cells has thus far been unsuccessful, presenting an obstacle to cloning XP genes. The authors chose an indirect route to transfer repair genes in chromosome fragments. DNA repair-competent (UV resistant) hybrid cell lines were established by PEG-mediated fusions of DNA repair-deficient (UV sensitive) human fibroblasts (XP12RO) with wild type Chinese hamster (CHO) cells (AA8). CHO cells were exposed to 5 Krad X-rays prior to fusions, predisposing hybrid cells to lose CHO chromosome fragments preferentially. Repair-competent hybrids were selected by periodic exposures to UV light. Secondary and tertiary hybrid cell lines were developed by fusion of X-irradiated hybrids to XP12RO. The hybrid cell lines exhibit resistance to UV that is comparable to that of CHO cells and they are proficient at repair replication after UV exposure. Whole cell DNA-DNA hybridizations indicate that the hybrids have greater homology to CHO DNA than is evident between XP12RO and CHO. These observations indicate that CHO DNA sequences which can function in repair of UV-damaged DNA in human cells have been transferred into the genome of the repair-deficient XP12RO cells

As the share of hybrid, plug-in hybrid (PHEV), electric (EV) and fuel-cell (FCV) vehicles grows in the national automotive fleet, an entirely new set of diagnostic and technical skills needs to be obtained by the maintenance workforce. Electrically-powered vehicles require new diagnostic tools, technique and vocabulary when compared to existing internal combustion engine-powered models. While the manufacturers of these new vehicles train their own maintenance personnel, training for students, independent working technicians and fleet operators is less focused and organized. This DOE-funded effort provided training to these three target groups to help expand availability of skills and to provide more competition (and lower consumer cost) in the maintenance of these hybrid- and electric-powered vehicles. Our approach was to start locally in the San Francisco Bay Area, one of the densest markets in the United States for these types of automobiles. We then expanded training to the Los Angeles area and then out-of-state to identify what types of curriculum was appropriate and what types of problems were encountered as training was disseminated. The fact that this effort trained up to 800 individuals with sessions varying from 2- day workshops to full-semester courses is considered a successful outcome. Diverse programs were developed to match unique time availability and educational needs of each of the three target audiences. Several key findings and observations arising from this effort include: • Recognition that hybrid and PHEV training demand is immediate; demand for EV training is starting to emerge; while demand for FCV training is still over the horizon • Hybrid and PHEV training are an excellent starting point for all EV-related training as they introduce all the basic concepts (electric motors, battery management, controllers, vocabulary, testing techniques) that are needed for all EVs, and these skills are in-demand in today’s market. • Faculty

Potentially damaging failure modes of high- and medium-voltage electrical equipment

International Nuclear Information System (INIS)

Hoy, H.C.

1983-07-01

The electrical equipment failures of both nuclear and nonnuclear public utilities were reviewed. Those failures that could pose an additional problem to surrounding and connected equipment were defined. The literature was searched; utilities, repair shops, and large electrical equipment users were contacted for failure information. The data were reviewed in detail, and failure modes were determined. Sample cascade failures are discussed. The failure rate of electrical equipment in utilities is historically quite low. Nuclear plants record too few failures to be statistically valid, but failures that have been recorded show that good design usually restricts the failure to a single piece of equipment

Electrical injuries have become a significant health problem in developing countries because of increase in access to electricity in the last few decades and lack of adequate safety measures. Electrical injuries of eyes are relatively uncommon. A case report of a rapid and complete corneal healing accompanied by satisfactory visual recovery after an electric burn event in a 20-year-old male is reported. The patient had accidental exposure to high voltage live wire while he was repairing it, resulting in severe ocular and superficial body burn. He was not wearing any protective equipment at the time of injury. On examination, the best-corrected visual acuity was counting fingers in the left eye with severe corneal epithelial loss and diffuse corneal oedema. The patient was treated medically, with a rapid corneal healing and resolution of oedema over the next few days. Visual acuity in the worse eye (left) improved to 20/25 from counting fingers.

Polychlorinated biphenyls (PCBs) are synthetic chemical compounds consisting of chlorine, carbon and hydrogen. They are very stable, fire resistant, do not conduct electricity and have low volatility at normal temperatures. They were mainly used as a cooling and insulating fluid for industrial transformers and capacitors. Some of the same properties that made PCBs so widely used, also make them environmentally hazardous, especially their extreme resistance to chemical and biological breakdown by natural processes in the environment. Typical chemicals associated with the presence of PCB oils are chlorobenzene, lead, xylene, and petroleum hydrocarbons. A case study of a transformer repair facility was discussed along with its soil and groundwater remediation. This presentation discussed the delineation program for the site which operated as a repair facility of PCB-containing transformers from 1968 until 1998. The property was bought by Siemens Canada Ltd. in 1998 and was sold in 2004. As part of the purchasing agreement, a Certificate of Compliance from the British Columbia Ministry of Environment was required. Remediation work was therefore needed. The presentation also covered: zones of contamination and contaminants of concern, soil impacts, groundwater impacts, and an evaluation of remediation options. In-situ treatment of soil with hydrogen peroxide and the selected remedial option were discussed. A soil economic analysis was also conducted. Last, challenges, solutions, and conclusions were presented. tabs., figs.

Bentonite electrical conductivity: a model based on series–parallel transport

KAUST Repository

Lima, Ana T.

2010-01-30

Bentonite has significant applications nowadays, among them as landfill liners, in concrete industry as a repairing material, and as drilling mud in oil well construction. The application of an electric field to such perimeters is under wide discussion, and subject of many studies. However, to understand the behaviour of such an expansive and plastic material under the influence of an electric field, the perception of its electrical properties is essential. This work serves to compare existing data of such electrical behaviour with new laboratorial results. Electrical conductivity is a pertinent parameter since it indicates how much a material is prone to conduct electricity. In the current study, total conductivity of a compacted porous medium was established to be dependent upon density of the bentonite plug. Therefore, surface conductivity was addressed and a series-parallel transport model used to quantify/predict the total conductivity of the system. © The Author(s) 2010.

The repair of UV-irradiated DNA of plasmid YEp13 was studied in the incision defective strains by measurement of cell transformation frequency. In Saccharomyces cerevisiae, rad1,2,3 and 4 mutants could repair UV-damaged plasmid DNA. In Escherichia coli, uvrA mutant was unable to repair UV-damaged plasmid DNA; however, pretreatment of the plasmid with Micrococcus luteus endonuclease increased repair. It was concluded that all the mutations of yeast were probably limited only to the nuclear DNA. (author)

DNA repair in Mycobacterium tuberculosis revisited.

Dos Vultos, Tiago; Mestre, Olga; Tonjum, Tone; Gicquel, Brigitte

2009-05-01

Our understanding of Mycobacterium tuberculosis DNA repair mechanisms is still poor compared with that of other bacterial organisms. However, the publication of the first complete M. tuberculosis genome sequence 10 years ago boosted the study of DNA repair systems in this organism. A first step in the elucidation of M. tuberculosis DNA repair mechanisms was taken by Mizrahi and Andersen, who identified homologs of genes involved in the reversal or repair of DNA damage in Escherichia coli and related organisms. Genes required for nucleotide excision repair, base excision repair, recombination, and SOS repair and mutagenesis were identified. Notably, no homologs of genes involved in mismatch repair were identified. Novel characteristics of the M. tuberculosis DNA repair machinery have been found over the last decade, such as nonhomologous end joining, the presence of Mpg, ERCC3 and Hlr - proteins previously presumed to be produced exclusively in mammalian cells - and the recently discovered bifunctional dCTP deaminase:dUTPase. The study of these systems is important to develop therapeutic agents that can counteract M. tuberculosis evolutionary changes and to prevent adaptive events resulting in antibiotic resistance. This review summarizes our current understanding of the M. tuberculosis DNA repair system.

Privatization of Electricity Service Delivery in Developing Nations: Issues and Challenges

Directory of Open Access Journals (Sweden)

Olamide Eniola Victor

2015-09-01

Full Text Available The provision of public utilities and infrastructures particularly electricity by the public sector (Government especially in the Developing Nations has been heavily criticized. This has been attributed to many reasons including poor electricity supply, poor distribution of service delivery of electricity due to the absence of spatial planning, insufficient government investment into the power industry, ineptitude operation on the part of the technicians, poor administration and managerial control. However, efforts to move away from government ownership, control or participation in this sector of economy towards free enterprise and increased inclusive private sector participation known as privatization, has been adopted as one of the solutions. This paper presents a critical review of privatization practices of alternative Service Delivery approach of selected Asian and African nations. The paper would elicit the common variants of privatization models adopted by these nations and the different implementation strategies which resulted in divergence in effectiveness and efficiency in the service delivery of electricity. The selected Asian countries are; Malaysia, India, and China, while the selected African nations are Nigeria, Cameroun and South Africa. The paper will draw from the literatures the various approaches, concepts adopted, practices, issues and challenges faced by these countries.

Electrical stimulation of schwann cells promotes sustained increases in neurite outgrowth.

Endogenous electric fields are instructive during embryogenesis by acting to direct cell migration, and postnatally, they can promote axonal growth after injury (McCaig 1991, Al-Majed 2000). However, the mechanisms for these changes are not well understood. Application of an appropriate electrical stimulus may increase the rate and success of nerve repair by directly promoting axonal growth. Previously, DC electrical stimulation at 50 mV/mm (1 mA, 8 h duration) was shown to promote neurite outgrowth and a more pronounced effect was observed if both peripheral glia (Schwann cells) and neurons were co-stimulated. If electrical stimulation is delivered to an injury site, both the neurons and all resident non-neuronal cells [e.g., Schwann cells, endothelial cells, fibroblasts] will be treated and this biophysical stimuli can influence axonal growth directly or indirectly via changes to the resident, non-neuronal cells. In this work, non-neuronal cells were electrically stimulated, and changes in morphology and neuro-supportive cells were evaluated. Schwann cell response (morphology and orientation) was examined after an 8 h stimulation over a range of DC fields (0-200 mV/mm, DC 1 mA), and changes in orientation were observed. Electrically prestimulating Schwann cells (50 mV/mm) promoted 30% more neurite outgrowth relative to co-stimulating both Schwann cells with neurons, suggesting that electrical stimulation modifies Schwann cell phenotype. Conditioned medium from the electrically prestimulated Schwann cells promoted a 20% increase in total neurite outgrowth and was sustained for 72 h poststimulation. An 11-fold increase in nerve growth factor but not brain-derived neurotrophic factor or glial-derived growth factor was found in the electrically prestimulated Schwann cell-conditioned medium. No significant changes in fibroblast or endothelial morphology and neuro-supportive behavior were observed poststimulation. Electrical stimulation is widely used in

Repair-modification of radiodamaged genes

Volpe, P.; Institute of Experimental Medicine, Rome; Eremenko, T.

1995-01-01

It is proposed that through repair-modification, the modified base 5mC may have facilitated the divergent evolution of coding (hypomethylated exon) and uncoding (hypermethylated promoter and intron) sequences in eukaryotic genes. The radioinduced repair patches appearing in regions lacking 5mC are fully reconstructed by excision-repair, whereas those appearing in regions containing 5mC are incompletely reconstructed by this conventional mechanism. Such a second class of repair patches may, however, become fully reconstructed, in the S phase, by repair-modification. In fact, while DNA polymerase β - which is a key enzyme of excision-repair - is active through the whole interphase. DNA methylase - which is responsible for post-synthetic DNA modification - is essentially active in S. Uncoupling of these two enzyme systems, outside S, might explain why in unsynchronised cells repair patches of non-replicating strands are hypomethylated when compared with specific methylation of replicating strands. In other words, excision-repair would always be able to re-establish the primary ATGC language of both damaged unmethylated and methylated regions, while repair-modification would be able to re-establish the modified ATGC(5mC) language of the damaged methylated regions, only in S, but not in G 1 or G 2 . In these two phases, when DNA methylation is inversely correlated with pre-mRNA transcription (as in the case of many tissue-specific genes), such demethylation might induce a silent transcriptional unit to become active.

Karasek's job strain model postulates that workers chronically exposed to adverse psychosocial work environment (high strain job)--high psychological job demands and low job control, including poor social support, increased physical demand and hazardous work condition--will eventually develop both physical illnesses such as cardiovascular diseases and psychological disorders such as depression. In order to determine the prevalence and associated factors of job-related depression, a cross-sectional study was conducted among laboratory technicians in Hospital Universiti Sains Malaysia (HUSM) and Kementerian Kesihatan Malaysia (KKM) Hospitals in Kelantan between September 2001 and February 2002. One hundred and two laboratory technicians in HUSM and 79 laboratory technicians in 7 KKM Hospitals were selected; 84/102 (82.4%) in HUSM and 71/79 (89.9%) in KKM Hospitals responded. Data was collected using self-administered questionnaires of the validated Malay version of the Job Content Questionnaire (JCQ) originally developed by Robert Karasek. Results indicated that the prevalence of high job strain in laboratory technicians in HUSM and KKM hospitals was 33.3% (28/84) and 26.8% (19/71), respectively (p>0.05). Significantly higher proportion (59.5%) (50/84) of laboratory technicians in HUSM compared to those in KKM Hospitals (39.4%) (28/71) (p = 0.016) experienced job-related depression. Significant associated factors of job-related depression were low social support (HUSM: adjusted OR 4.7, 95% CI 1.2-18.8; KKM: adjusted OR 14.8, 95%CI 2.4-89.3), high psychological demand (HUSM: adjusted OR 3.0, 95%CI 1.0-8.8), and low decision authority (KKM: adjusted OR 9.7, 95%CI 1.0-91.1). We conclude that strengthening the social support network (supervisors' and coworkers' support), reducing psychological job demand, and increasing decision-making authority of laboratory technicians may go a long way towards reducing job-related depression.

Repair promoted by plasmid pKM101 is different from SOS repair

Goze, A.; Devoret, R.

In E. coli K12 bacteria carrying plasmid pKM101, prophage lambda was induced at UV doses higher than in plasmid-less parental bacteria. UV-induced reactivation per se was less effective. Bacteria with pKM101 showed no alteration in their division cycle. Plasmid PKM101 coded for a constitutive error-prone repair different from the inducible error-prone repair called SOS repair. Plasmid pKM101 protected E. coli bacteria from UV damage but slightly sensitized them to X-ray lesions. Protection against UV damage was effective in mutant bacteria deficient in DNA excision-repair provided that the recA, lexA and uvrE genes were functional. Survival of phages lambda and S13 after UV irradiation was enhanced in bacteria carrying plasmid pKM101; phage lambda mutagenesis was also increased. Plasmid pKM101 repaired potentially lethal DNA lesions, although Wild-type DNA sequences may not necessarily be restored; hence the mutations observed are the traces of the original DNA lesions.

Full Text Available Occupational exposure to lead is common among automobile technicians and constitutes 0.9% of total global health burden with a majority of cases in developing countries. The aim of this study was to determine and compare the blood lead levels of automobile technicians in roadside and organised garages in Lagos State, Nigeria. This was a comparative cross-sectional study. Data were collected using interviewer-administered questionnaires. Physical examinations were conducted and blood was analysed for lead using atomic spectrophotometery. Statistical analyses were performed to compare the median blood lead levels of each group using the independent sample (Mann-Whitney U test. Seventy-three (40.3% of the organised compared to 59 (34.3% of the roadside groups had high blood lead levels. The organised group had statistically significant higher median blood lead levels of, 66.0 µg/dL than the roadside 43.5 µg/dL (P < 0.05. There was also statistically significant association between high blood lead levels and abnormal discolouration of the mucosa of the mouth in the organised group. Automobile technicians in organised garages in Lagos have higher prevalence of elevated blood lead levels and higher median levels than the roadside group. Preventive strategies against lead exposures should be instituted by the employers and further actions should be taken to minimize exposures, improve work practices, implement engineering controls (e.g., proper ventilation, and ensure the use of personal protective equipment.

Experiments on the combined action of radiation and a DNA inhibitor using Crepis roots and on split-dose irradiation of human lymphocytes lead to the conclusion that there are two types of repair. The 'regular' repair takes place twice in each mitotic cycle and ensures the maintenance of genetic stability. The 'emergency' repair is induced at all stages of the mitotic cycle by high levels of injury. (author)

Background Drug diversion by health care personnel poses a risk for serious patient harm. Public health identified 2 patients diagnosed with acute hepatitis C virus (HCV) infection who shared a common link with a hospital. Further investigation implicated a drug-diverting, HCV-infected surgical technician who was subsequently employed at an ambulatory surgical center. Methods Patients at the 2 facilities were offered testing for HCV infection if they were potentially exposed. Serum from the surgical technician and patients testing positive for HCV but without evidence of infection before their surgical procedure was further tested to determine HCV genotype and quasi-species sequences. Parenteral medication handling practices at the 2 facilities were evaluated. Results The 2 facilities notified 5970 patients of their possible exposure to HCV, 88% of whom were tested and had results reported to the state public health departments. Eighteen patients had HCV highly related to the surgical technician’s virus. The surgical technician gained unauthorized access to fentanyl owing to limitations in procedures for securing controlled substances. Conclusions Public health surveillance identified an outbreak of HCV infection due to an infected health care provider engaged in diversion of injectable narcotics. The investigation highlights the value of public health surveillance in identifying HCV outbreaks and uncovering a method of drug diversion and its impacts on patients. PMID:25442395

When is cartilage repair successful?

Focal cartilage lesions are a cause of long-term disability and morbidity. After cartilage repair, it is crucial to evaluate long-term progression or failure in a reproducible, standardized manner. This article provides an overview of the different cartilage repair procedures and important characteristics to look for in cartilage repair imaging. Specifics and pitfalls are pointed out alongside general aspects. After successful cartilage repair, a complete, but not hypertrophic filling of the defect is the primary criterion of treatment success. The repair tissue should also be completely integrated to the surrounding native cartilage. After some months, the transplants signal should be isointense compared to native cartilage. Complications like osteophytes, subchondral defects, cysts, adhesion and chronic bone marrow edema or joint effusion are common and have to be observed via follow-up. Radiological evaluation and interpretation of postoperative changes should always take the repair method into account. (orig.) [de

Meniscal repair devices not requiring accessory incisions are attractive. Many factors contribute to their clinical effectiveness including their biomechanical characteristics. This study compared several new meniscal repair devices with standard meniscal suture techniques. Using a porcine model, axis-of-insertion loads were applied to various meniscal sutures and repair devices. A single device or stitch was placed in a created meniscal tear and a load applied. Both loads and modes of failure were recorded. The load-to-failure data show stratification into 4 distinct statistical groups. Group A, 113 N for a double vertical stitch; group B, 80 N for a single vertical stitch; group C, 57 N for the BioStinger, 56 N for a horizontal mattress stitch, and 50 N for the T-Fix stitch; and group D, 33 N for the Meniscus Arrow (inserted by hand or gun), 32 N for the Clearfix screw, 31 N for the SDsorb staple, 30 N for the Mitek meniscal repair system, and 27 N for the Biomet staple. The failure mechanism varied. Sutures broke away from the knot. The Meniscus Arrow and BioStinger pulled through the inner rim with the crossbar intact. The Clearfix screw failed by multiple mechanisms, whereas 1 leg of the SDsorb staple always pulled out of the outer rim. The Mitek device usually failed by pullout from the inner rim. The Biomet staple always broke at the crosshead or just below it. Although the surgeon should be aware of the material properties of the repair technique chosen for a meniscal repair, this information is only an indication of device performance and may not correlate with clinical healing results.

The nursing profession faces continuous transformations demonstrating the importance of professional continuing education to extend knowledge following technological development without impairing quality of care. Nursing assistants and technicians account for nearly 80% of nursing professionals in Brazil and are responsible for uninterrupted patient care. Extensive knowledge improvement is needed to achieve excellence in nursing care. The objective was to develop and evaluate a continuing education program for nursing technicians at a pediatric cardiac intensive care unit (PCICU) using a virtual learning environment entitled EDUCATE. From July to September 2015, a total of 24 nursing technicians working at the PCICU at a children's hospital located in the northwestern region of São Paulo state (Brazil) fully participated in the continuing education program developed in a virtual learning environment using Wix platform, allowing access to video classes and pre- and post-training theoretical evaluation questionnaires outside the work environment. The evaluation tools recorded participants' knowledge evolution, technological difficulties, educational, and overall rating. Knowledge development was descriptively presented as positive in more than 66.7%. Content and training were considered "excellent" by most participants and 90% showed an interest in the use of technological resources. Technical difficulties were found and quickly resolved by 40% of participants including Internet access, login, and lack of technical expertise. The continuing education program using a virtual learning environment positively contributed to the improvement in theoretical knowledge of nursing technicians in PCICU.

Residual stress by repair welds

Mochizuki, Masahito; Toyoda, Masao

2003-01-01

Residual stress by repair welds is computed using the thermal elastic-plastic analysis with phase-transformation effect. Coupling phenomena of temperature, microstructure, and stress-strain fields are simulated in the finite-element analysis. Weld bond of a plate butt-welded joint is gouged and then deposited by weld metal in repair process. Heat source is synchronously moved with the deposition of the finite-element as the weld deposition. Microstructure is considered by using CCT diagram and the transformation behavior in the repair weld is also simulated. The effects of initial stress, heat input, and weld length on residual stress distribution are studied from the organic results of numerical analysis. Initial residual stress before repair weld has no influence on the residual stress after repair treatment near weld metal, because the initial stress near weld metal releases due to high temperature of repair weld and then stress by repair weld regenerates. Heat input has an effect for residual stress distribution, for not its magnitude but distribution zone. Weld length should be considered reducing the magnitude of residual stress in the edge of weld bead; short bead induces high tensile residual stress. (author)

Secondary surgical repair of ankle ligaments is often indicated in cases of chronic lateral ankle instability. Recently, arthroscopic Broström techniques have been described, but biomechanical information is limited. The purpose of the present study was to analyze the biomechanical properties of an arthroscopic Broström repair and augmented repair with a proximally placed suture anchor. It was hypothesized that the arthroscopic Broström repairs would compare favorably to open techniques and that augmentation would increase the mean repair strength at time zero. Twenty (10 matched pairs) fresh-frozen foot and ankle cadaveric specimens were obtained. After sectioning of the lateral ankle ligaments, an arthroscopic Broström procedure was performed on each ankle using two 3.0-mm suture anchors with #0 braided polyethylene/polyester multifilament sutures. One specimen from each pair was augmented with a 2.9-mm suture anchor placed 3 cm proximal to the inferior tip of the lateral malleolus. Repairs were isolated and positioned in 20 degrees of inversion and 10 degrees of plantarflexion and loaded to failure using a dynamic tensile testing machine. Maximum load (N), stiffness (N/mm), and displacement at maximum load (mm) were recorded. There were no significant differences between standard arthroscopic repairs and the augmented repairs for mean maximum load and stiffness (154.4 ± 60.3 N, 9.8 ± 2.6 N/mm vs 194.2 ± 157.7 N, 10.5 ± 4.7 N/mm, P = .222, P = .685). Repair augmentation did not confer a significantly higher mean strength or stiffness at time zero. Mean strength and stiffness for the arthroscopic Broström repair compared favorably with previous similarly tested open repair and reconstruction methods, validating the clinical feasibility of an arthroscopic repair. However, augmentation with an additional proximal suture anchor did not significantly strengthen the repair. © The Author(s) 2015.

Core competencies are considered the foundation for establishing Emergency Medical Technician (EMT) and paramedic curricula, and for ensuring performance standards in the delivery of prehospital care. This study surveyed EMT instructors and medical directors to identify the most desirable core competencies for all levels of EMTs in Taiwan. A principal components analysis with Varimax rotation was conducted. An online questionnaire was distributed to obtain perspectives of EMT instructors and medical directors on the most desirable core competencies for EMTs. The target population was EMT training-course instructors and medical directors of fire departments in Taiwan. The questionnaire comprised 61 competency items, and multiple-choice and open-ended questions were used to obtain respondents' perspectives of the Taiwanese EMT training and education system. The results identified three factors at EMT-1 and EMT-2 levels and five factors at the EMT-Paramedic level. The factors for EMT-1 and EMT-2 were similar, and those for EMT-Paramedics identified further comprehensive competence perspectives. The key factors that appear to influence the development of the Taiwanese Emergency Medical Services (EMS) education system are the attitude of authorities, the licensure system, and legislation. The findings present new core competencies for the Taiwanese EMT system and provide capacity to redesign curricula and reconsider roles for EMT-1 and EMT-2 technicians. At the EMT-Paramedic level, the findings demonstrate the importance of incorporating competency standards in the current skills-based curriculum. Moreover, the core-competencies gap that exists between Taiwanese EMT-1s, EMT-2s, and EMT-Paramedics and internationally recognized core competencies needs to be addressed. By identifying the key factors that potentially impact the development of the EMS education system, such as the attitude of authorities, the licensure system, and legislation, these findings will inform

GPA/GPSA/OSU-Okmulgee natural gas compression technician training program

Energy Technology Data Exchange (ETDEWEB)

Doede, S.

1999-07-01

Approximately one year ago, OSU-Okmulgee and the Gas Processors Association began discussions about the possibility of developing a natural Gas Technician Training Program for GPA members. Following a presentation to the Membership and Services Committee, Chairman John Ehlers solicited and obtained the approval of the GPA Executive Committee to sponsor the program. Participation in the program was also made available to GPSA members. The purpose of the program is to upgrade the technical competency and professional level of incoming natural gas compression technicians. It educates students to analytically diagnose, service and maintain gas compression equipment and systems using industry recommended procedures, special tools and service information. It also provides course content, which will enable successful graduates to advance in position after additional experience, and to understand new systems, technologies and components as they are introduced. The two-year Associate-In-Applied Science Degree program includes six successive college semesters. Nearly one-half of the time is designated for technical/academic education at Oklahoma State University-Okmulgee with the balance of time allocated for on-the-job internship experiences at sponsoring GPA/GPSA members. Each block of technical education and general education course work is followed by an immediate work experience time period designated to reinforce the technical and general education. These time periods are approximately seven and one-half weeks in length each. It is essential for the success of the students and the program that the students' education at OSU-Okmulgee and work experiences at GPA/GPSA member facilities be closely aligned for maximum student learning and retention. In addition to technical classes on gas compression equipment and components, the courses offered in math, speech, technical writing, psychology and ethics for example, prepare students to be able to communicate well, get

The time course of repair of ultraviolet-induced DNA damage; implications for the structural organization of repair

International Nuclear Information System (INIS)

Collins, A.; Squires, S.

1986-01-01

Alternative molecular mechanisms can be envisaged for the cellular repair of UV-damaged DNA. In the 'random collision' model, DNA damage distributed throughout the genome is recognised and repaired by a process of random collision between DNA damage and repair enzymes. The other model assumes a 'processive' mechanism, whereby DNA is scanned for damage by a repair complex moving steadily along its length. Random collision should result in a declining rate of repair with time as the concentration of lesions in the DNA falls; but the processive model predicts a constant rate until scanning is complete. The authors have examined the time course of DNA repair in human fibroblasts given low doses of UV light. Using 3 distinct assays, the authors find no sign of a constant repair rate after 4 J/m 2 or less, even when the first few hours after irradiation are examined. Thus DNA repair is likely to depend on random collision. (Auth.)

Study of the combined action of gamma radiation and static electric fields in human cells

The basic principle of radiotherapy is the one of maximizing damage to the tumor, while minimizing it in neighboring health tissues. Several strategies have been worked out aiming at increasing cellular radiosensitivity, and among them is the use of exogenous fields. Our goal in this work is the study in human cells of the effect resulting from the association of irradiation with exposure to exogenous static electric fields. The T47D cell line of breast cancer cells was irradiated with gammas in the 0 - 8 Gy doses range. The corresponding survival curve provided information on the radiosensitivity of this cell line. The rate of cell deaths per Gray in the 0 - 8 Gy range exhibited a maximum at 2 Gy, which corresponds to the most efficient irradiation dose. The viability of this T47D cells exposed to both gamma radiation and 1.250 V/cm static electric field (SEF) was about 12% lower than when only irradiated. The sole exposure of the cells to SEF by 24 and 72 hours didn't induce toxicity. Immunofluorescence runs carried out in irradiated normal MRC5 cell line of human lung fibroblast, without and with exposition to a SEF, have quantified the expression of the y- H2AX histone. The amount of phosphorylated histones was approximately 40% higher after irradiation with 2 Gy plus exposure to a SEF by 1 hour, showing that the electric field negatively interfered in the repairing process of the DNA double strand breaks. The flow cytometry analysis with FACS allowed the investigation of a possible interference of radiation and SEF in the cell distributions among the cellular cycle phases. It was found that in T47D cells treated with 1 and 2 Gy by 24 hours the SEF also negatively interfered in the DNA repairing process, as evidenced by the higher accumulation of cells in the S phase. Therefore, it would be possible to conclude that static and exogenous electric fields are able of negatively interfering in the cellular repair and, presumably, in DNA repair. (author)

Many all-inside suture-based devices are currently available, including the Meniscal Cinch, FasT-Fix, Ultra FasT-Fix, RapidLoc, MaxFire, and CrossFix System. These different devices have been compared in various configurations, but to our knowledge, the Sequent meniscal repair device, which applies running sutures, has not been compared with the Ultra FasT-Fix, nor has it been compared with its suture, No. 0 Hi-Fi, using an inside-out repair technique. To assess the quality of the meniscal repair, all new devices should be compared with the gold standard: the inside-out repair. To that end, this study aims to compare the biomechanical characteristics of running sutures delivered by the Sequent meniscal repair device with 2 vertical mattress sutures applied using the Ultra FasT-Fix device and with 2 vertical mattress sutures using an inside-out repair technique with No. 0 Hi-Fi suture. Controlled laboratory study. Paired (medial and lateral), fresh-frozen porcine menisci were randomly assigned to 1 of 3 groups: Sequent (n = 17), Ultra FasT-Fix (n = 19), and No. 0 Hi-Fi inside-out repair (n = 20). Bucket-handle tears were created in all menisci and were subjected to repair according to their grouping. Once repaired, the specimens were subjected to cyclic loading (100, 300, and 500 cycles), followed by loading to failure. The Sequent and Ultra FasT-Fix device repairs and the suture repair exhibited low initial displacements. The Sequent meniscal repair device demonstrated the lowest displacement in response to cyclic loading. No. 0 Hi-Fi suture yielded the highest load to failure. With the development of the next generation of all-inside meniscal repair devices, surgeons may use these findings to select the method best suited for their patients. The Sequent meniscal repair device displays the least amount of displacement during cyclic loading but has a similar failure load to other devices.

Thymus repair compared with hemopoiesis repair in spleen after protracted irradiation

International Nuclear Information System (INIS)

Mackova, N.

1987-01-01

Matured female mice of ICR strain were irradiated from a 60 Co source with a daily dose rate of 5 Gy till total accumulated dose of 10 Gy for 2 days. Animals were examined in various intervals within 42 days after irradiation. The results revealed that protracted irradiation will induce a massive injury to hemopoiesis. The first repair processes occurred in thymus and were characterized by two phases. The first repair wave peaked about the day 10 and the second about the day 30 after irradiation. The repair processes observed in the red pulp of the spleen reached their highest intensity approximately between the days 14-16 after irradiation. (author)

Andreski, Michael; Myers, Megan; Gainer, Kate; Pudlo, Anthony

Determine the effects of an 18-month pilot project using tech-check-tech in 7 community pharmacies on 1) rate of dispensing errors not identified during refill prescription final product verification; 2) pharmacist workday task composition; and 3) amount of patient care services provided and the reimbursement status of those services. Pretest-posttest quasi-experimental study where baseline and study periods were compared. Pharmacists and pharmacy technicians in 7 community pharmacies in Iowa. The outcome measures were 1) percentage of technician verified refill prescriptions where dispensing errors were not identified on final product verification; 2) percentage of time spent by pharmacists in dispensing, management, patient care, practice development, and other activities; 3) the number of pharmacist patient care services provided per pharmacist hours worked; and 4) percentage of time that technician product verification was used. There was no significant difference in overall errors (0.2729% vs. 0.5124%, P = 0.513), patient safety errors (0.0525% vs. 0.0651%, P = 0.837), or administrative errors (0.2204% vs. 0.4784%, P = 0.411). Pharmacist's time in dispensing significantly decreased (67.3% vs. 49.06%, P = 0.005), and time in direct patient care (19.96% vs. 34.72%, P = 0.003), increased significantly. Time in other activities did not significantly change. Reimbursable services per pharmacist hour (0.11 vs. 0.30, P = 0.129), did not significantly change. Non-reimbursable services increased significantly (2.77 vs. 4.80, P = 0.042). Total services significantly increased (2.88 vs. 5.16, P = 0.044). Pharmacy technician product verification of refill prescriptions preserved dispensing safety while significantly increasing the time spent in delivery of pharmacist provided patient care services. The total number of pharmacist services provided per hour also increased significantly, driven primarily by a significant increase in the number of non

Laparoscopic totally extraperitoneal inguinal hernia repair: lessons learned from 3,100 hernia repairs over 15 years.

Two revolutions in inguinal hernia repair surgery have occurred during the last two decades. The first was the introduction of tension-free hernia repair by Liechtenstein in 1989 and the second was the application of laparoscopic surgery to the treatment of inguinal hernia in the early 1990s. The purposes of this study were to assess the safety and effectiveness of laparoscopic totally extraperitoneal (TEP) repair and to discuss the technical changes that we faced on the basis of our accumulative experience. Patients who underwent an elective inguinal hernia repair at the Department of Abdominal Surgery at the Institute of Laparoscopic Surgery (ILS), Bordeaux, between June 1990 and May 2005 were enrolled retrospectively in this study. Patient demographic data, operative and postoperative course, and outpatient follow-up were studied. A total of 3,100 hernia repairs were included in the study. The majority of the hernias were repaired by TEP technique; the repair was done by transabdominal preperitoneal (TAPP) repair in only 3%. Eleven percent of the hernias were recurrences after conventional repair. Mean operative time was 17 min in unilateral hernia and 24 min in bilateral hernia. There were 36 hernias (1.2%) that required conversion: 12 hernias were converted to open anterior Liechtenstein and 24 to laparoscopic TAPP technique. The incidence of intraoperative complications was low. Most of the patients were discharged at the second day of the surgery. The overall postoperative morbidity rate was 2.2%. The incidence of recurrence rate was 0.35%. The recurrence rate for the first 200 repairs was 2.5%, but it decreased to 0.47% for the subsequent 1,254 hernia repairs According to our experience, in the hands of experienced laparoscopic surgeons, laparoscopic hernia repair seems to be the favored approach for most types of inguinal hernias. TEP is preferred over TAPP as the peritoneum is not violated and there are fewer intra-abdominal complications.

Experiments are described which were conducted at the JPL Advanced Teleoperator Lab to demonstrate and evaluate the effectiveness of various teleoperator control modes in the performance of a simulated Solar Max Satellite Repair (SMSR) task. THe SMSR was selected as a test because it is very rich in performance capability requirements and it actually has been performed by two EVA astronauts in the Space Shuttle Bay in 1984. The main subtasks are: thermal blanket removal; installation of a hinge attachment for electrical panel opening; opening of electrical panel; removal of electrical connectors; relining of cable bundles; replacement of electrical panel; securing parts and cables; re-mate electrical connectors; closing of electrical panel; and reinstating thermal blanket. The current performance experiments are limited to thermal blanket cutting, electrical panel unbolting and handling electrical bundles and connectors. In one formal experiment even different control modes were applied to the unbolting and reinsertion of electrical panel screws subtasks. The seven control modes are alternative combinations of manual position and rate control with force feedback and remote compliance referenced to force-torque sensor information. Force-torque sensor and end effector position data and task completion times were recorded for analysis and quantification of operator performance.

Repair tension of a torn rotator cuff can affect healing after repair. However, a measurement of the actual tension during arthroscopic rotator cuff repair is not feasible. The relationship between repair tension and healing of a rotator cuff repair remains unclear. The purpose of this study was to evaluate the effect of repair tension on healing at the repair site. The hypothesis was that repair tension would be a major factor in determining the anatomic outcome of rotator cuff repair. Cohort study; Level of evidence, 2. Arthroscopic rotator cuff repairs (132 patients) for full-thickness rotator cuff tears were analyzed. An intraoperative model was designed for the estimation of repair tension using a tensiometer. Magnetic resonance imaging (MRI) was performed approximately 1 year (mean [±SD], 12.7 ± 3.2 months) postoperatively for the evaluation of healing at the repair site. Multivariable analysis was performed for tear size, amount of retraction, and fatty degeneration (FD) of rotator cuff muscles. The mean repair tension measured during the arthroscopic procedure was 28.5 ± 23.1 N. There was a statistically significant correlation between tension and tear size (Pearson correlation coefficient [PCC], 0.529; P repair tension also showed a significant inverse correlation with healing at the repair site (SCC, 0.195; P = .025). However, when sex, age, tear size, amount of retraction, tendon quality, and FD of rotator cuff muscles were included for multivariable logistic regression analysis, only FD of the infraspinatus showed an association with the anatomic outcome of repair (Exp(B) = 0.596; P = .010). Our intraoperative model for the estimation of rotator cuff repair tension showed an inverse correlation of repair tension with healing at the repair site, suggesting that complete healing is less likely with high-tension repairs. A significant association was observed on MRI between a high level of FD of the infraspinatus and repaired tendon integrity. © 2016

The purpose of the present study was to evaluate the effects of different repair resins and surface treatments on the repair strength of a polyamide denture base material. Polyamide resin specimens were prepared and divided into nine groups according to the surface treatments and repair materials. The flexural strengths were measured with a 3-point bending test. Data were analyzed with a 2-way analysis of variance, and the post-hoc Tukey test (α=0.05). The effects of the surface treatments on the surface of the polyamide resin were examined using scanning electron microscopy. The repair resins and surface treatments significantly affected the repair strength of the polyamide denture base material (p0.05). The flexural strength of the specimens repaired with the polyamide resin was significantly higher than that of those repaired with the heat-polymerized and autopolymerizing acrylic resins.

Luxardi, Guillaume; Reid, Brian; Maillard, Pauline; Zhao, Min

2014-07-24

Breaching of the cell membrane is one of the earliest and most common causes of cell injury, tissue damage, and disease. If the compromise in cell membrane is not repaired quickly, irreversible cell damage, cell death and defective organ functions will result. It is therefore fundamentally important to efficiently repair damage to the cell membrane. While the molecular aspects of single cell wound healing are starting to be deciphered, its bio-physical counterpart has been poorly investigated. Using Xenopus laevis oocytes as a model for single cell wound healing, we describe the temporal and spatial dynamics of the wound electric current circuitry and the temporal dynamics of cell membrane potential variation. In addition, we show the role of calcium influx in controlling electric current circuitry and cell membrane potential variations. (i) Upon wounding a single cell: an inward electric current appears at the wound center while an outward electric current is observed at its sides, illustrating the wound electric current circuitry; the cell membrane is depolarized; calcium flows into the cell. (ii) During cell membrane re-sealing: the wound center current density is maintained for a few minutes before decreasing; the cell membrane gradually re-polarizes; calcium flow into the cell drops. (iii) In conclusion, calcium influx is required for the formation and maintenance of the wound electric current circuitry, for cell membrane re-polarization and for wound healing.

Treatment and Controversies in Paraesophageal Hernia Repair

Directory of Open Access Journals (Sweden)

2015-04-01

Full Text Available Background: Historically all paraesophageal hernias were repaired surgically, today intervention is reserved for symptomatic paraesophageal hernias. In this review, we describe the indications for repair and explore the controversies in paraesophageal hernia repair, which include a comparison of open to laparoscopic paraesophageal hernia repair, the necessity of complete sac excision, the routine performance of fundoplication, and the use of mesh for hernia repair.Methods: We searched Pubmed for papers published between 1980 and 2015 using the following keywords: hiatal hernias, paraesophageal hernias, regurgitation, dysphagia, gastroesophageal reflux disease, aspiration, GERD, endoscopy, manometry, pH monitoring, proton pump inhibitors, anemia, iron deficiency anemia, Nissen fundoplication, sac excision, mesh, mesh repair. Results: Indications for paraesophageal hernia repair have changed, and currently symptomatic paraesophageal hernias are recommended for repair. In addition, it is important not to overlook iron-deficiency anemia and pulmonary complaints, which tend to improve with repair. Current practice favors a laparoscopic approach, complete sac excision, primary crural repair with or without use of mesh, and a routine fundoplication.

Double-Strand DNA Break Repair in Mycobacteria.

Science.gov (United States)

Glickman, Michael S

2014-10-01

Discontinuity of both strands of the chromosome is a lethal event in all living organisms because it compromises chromosome replication. As such, a diversity of DNA repair systems has evolved to repair double-strand DNA breaks (DSBs). In part, this diversity of DSB repair systems has evolved to repair breaks that arise in diverse physiologic circumstances or sequence contexts, including cellular states of nonreplication or breaks that arise between repeats. Mycobacteria elaborate a set of three genetically distinct DNA repair pathways: homologous recombination, nonhomologous end joining, and single-strand annealing. As such, mycobacterial DSB repair diverges substantially from the standard model of prokaryotic DSB repair and represents an attractive new model system. In addition, the presence in mycobacteria of a DSB repair system that can repair DSBs in nonreplicating cells (nonhomologous end joining) or when DSBs arise between repeats (single-strand annealing) has clear potential relevance to Mycobacterium tuberculosis pathogenesis, although the exact role of these systems in M. tuberculosis pathogenesis is still being elucidated. In this article we will review the genetics of mycobacterial DSB repair systems, focusing on recent insights.
