    Full Text Available Abstract Background Anti-psychotics, prescribed to people with dementia, are associated with approximately 1,800 excess annual deaths in the UK. A key public health objective is to limit such prescribing of anti-psychotics. Methods This project was conducted within primary care in Medway Primary Care Trust (PCT in the UK. There were 2 stages for the intervention. First, primary care information systems including the dementia register were searched by a pharmacy technician to identify people with dementia prescribed anti-psychotics. Second, a trained specialist pharmacist conducted targeted clinical medication reviews in people with dementia initiated on anti-psychotics by primary care, identified by the data search. Results Data were collected from 59 practices. One hundred and sixty-one (15.3% of 1051 people on the dementia register were receiving low-dose anti-psychotics. People with dementia living in residential homes were nearly 3.5 times more likely to receive an anti-psychotic [25.5% of care home residents (118/462 vs. 7.3% of people living at home (43/589] than people living in their own homes (p  Of the 161 people with dementia prescribed low-dose anti-psychotics, 91 were receiving on-going treatment from local secondary care mental health services or Learning Disability Teams. Of the remaining 70 patients the anti-psychotic was either withdrawn, or the dosage was reduced, in 43 instances (61.4% following the pharmacy-led medication review. Conclusions In total 15.3% of people on the dementia register were receiving a low-dose anti-psychotic. However, such data, including the recent national audit may under-estimate the usage of anti-psychotics in people with dementia. Anti-psychotics were used more commonly within care home settings. The pharmacist-led medication review successfully limited the prescribing of anti-psychotics to people with dementia.

    With the development of technology, medical equipment plays a more important role in the modern hospital. Medical equipment provides images, physiological results or other schematics of the patients to help doctors deal with the routines. It is also the major tool to the lab assistant in the clinical teaching and studies. It becomes one of a symbol of the technological level in modern hospital. The director of the hospital should establish an efficacious management pattern to manage the medical equipment, so that it will be operated in good condition to insure the safety of the patients. Since the maintenance is an important part of medical equipment management, it is significant that the hospital should establish a system to fit for itself. The study reviews the issues in hospital medical equipment maintenance management, the development of the maintenance management model and the characteristics, as well as the status at home and abroad. The research has been finished by using literature research method, questionnaire survey method and data analysis method. Then we analyze the current status of hospital medical equipment maintenance management model to find the problems. Based on the authentic and effective data from the survey, we can deduce the overview about the maintenance model in Beijing. The paper discusses the advantages and the disadvantages between the different model, and it makes suggestions on the follow aspects, such as system management, quality management, personnel management, cost management, information management perspective.

    2016-04-01

    For clinical management of different forms of psychosis, both classical and atypical anti-psychotic drugs (APDs) are available. These drugs are widely prescribed, even during pregnancy considering their minimal extra-pyramidal side effects and teratogenic potential compared to classical APDs. Among AAPDs, risperidone (RIS) is a first-line drug of choice by physicians. The molecular weight of RIS is 410.49 g/mol; hence, it can easily cross the placental barrier and enter the foetal bloodstream. It is not known whether or not AAPDs like RIS may affect the developing placenta and foetus adversely. Reports on this issue are limited and sketchy. Therefore, this study has evaluated the effects of maternal exposure to equivalent therapeutic doses of RIS on placental growth, histopathological and cytoarchitectural changes, and to establish a relationship between placental dysfunction and foetal outcomes. Pregnant rats (n = 24) were exposed to selected doses (0.8, 1.0 and 2.0 mg/kg) of RIS from gestation days 6-21. These dams were sacrificed; their placentas and foetuses were collected, morphometrically examined and further processed for histopathological examination. This study revealed that in utero exposure to equivalent therapeutic doses of RIS during organogenesis-induced placental dystrophy (size and weight), disturbed cytoarchitectural organization (thickness of different placental layers), histopathological lesions (necrosis in trophoblast with disruption of trophoblastic septa and rupturing of maternal-foetal interface) and intrauterine growth restriction of the foetuses. It may be concluded that multifactorial mechanisms might be involved in the dysregulation of structure and function of the placenta and of poor foetal growth and development. PMID:27256515

    Preventive maintenance is a core function of clinical engineering, and it is essential to guarantee the correct functioning of the equipment. The management and control of maintenance activities are equally important to perform maintenance. As the variety of medical equipment increases, accordingly the size of maintenance activities increases, the need for better management and control become essential. This paper aims to develop a new model for preventive maintenance priority of medical equipment using quality function deployment as a new concept in maintenance of medical equipment. We developed a three-domain framework model consisting of requirement, function, and concept. The requirement domain is the house of quality matrix. The second domain is the design matrix. Finally, the concept domain generates a prioritization index for preventive maintenance considering the weights of critical criteria. According to the final scores of those criteria, the prioritization action of medical equipment is carried out. Our model proposes five levels of priority for preventive maintenance. The model was tested on 200 pieces of medical equipment belonging to 17 different departments of two hospitals in Piedmont province, Italy. The dataset includes 70 different types of equipment. The results show a high correlation between risk-based criteria and the prioritization list.

    Methadone medical maintenance (MMM) reduces the reporting schedule for stable and well-functioning methadone maintenance patients to once a month, with counseling provided by medical staff. We report on the 12-month outcomes of 92 highly stable methadone maintenance patients randomly assigned to one of three study conditions: routine care, MMM at the methadone maintenance program, and MMM at a physician's office. Methadone medical maintenance patients received a 28-day supply of methadone, whereas routine care patients received five or six take-home methadone doses each week. All patients performed a medication recall once a month and submitted two urine samples each month. An adaptive stepped-care system of treatment intensification was used for patients who failed recall or who had drug-positive urine specimens. Seventy-seven patients completed the 12-month study period. Dropout was caused primarily by problems with handling methadone and disliking the recall frequency. There were low rates of drug use or failed medication recall. Treatment satisfaction was high in all groups, but the MMM patients initiated more new employment or family/social activities than did routine care patients over the study period. The stepped-care approach was well tolerated and matched patients to an appropriate step of service within a continuum of treatment intensity. PMID:17084792

  17. A model for preemptive maintenance of medical linear accelerators—predictive maintenance

    International Nuclear Information System (INIS)

    Unscheduled accelerator downtime can negatively impact the quality of life of patients during their struggle against cancer. Currently digital data accumulated in the accelerator system is not being exploited in a systematic manner to assist in more efficient deployment of service engineering resources. The purpose of this study is to develop an effective process for detecting unexpected deviations in accelerator system operating parameters and/or performance that predicts component failure or system dysfunction and allows maintenance to be performed prior to the actuation of interlocks. The proposed predictive maintenance (PdM) model is as follows: 1) deliver a daily quality assurance (QA) treatment; 2) automatically transfer and interrogate the resulting log files; 3) once baselines are established, subject daily operating and performance values to statistical process control (SPC) analysis; 4) determine if any alarms have been triggered; and 5) alert facility and system service engineers. A robust volumetric modulated arc QA treatment is delivered to establish mean operating values and perform continuous sampling and monitoring using SPC methodology. Chart limits are calculated using a hybrid technique that includes the use of the standard SPC 3σ limits and an empirical factor based on the parameter/system specification. There are 7 accelerators currently under active surveillance. Currently 45 parameters plus each MLC leaf (120) are analyzed using Individual and Moving Range (I/MR) charts. The initial warning and alarm rule is as follows: warning (2 out of 3 consecutive values ≥ 2σ hybrid) and alarm (2 out of 3 consecutive values or 3 out of 5 consecutive values ≥ 3σ hybrid). A customized graphical user interface provides a means to review the SPC charts for each parameter and a visual color code to alert the reviewer of parameter status. Forty-five synthetic errors/changes were introduced to test the effectiveness of our initial chart limits. Forty

    Full Text Available Hepatocellular carcinoma (HCC is one of the leading causes of cancer-related deaths worldwide. Surgical resection and conventional chemotherapy and radiotherapy ultimately fail due to tumor recurrence and HCC's resistance. The development of novel therapies against HCC is thus urgently required. The cyclin-dependent kinase (CDK pathways are important and well-established targets for cancer treatment. In particular, CDK2 is a key factor regulating the cell cycle G1 to S transition and a hallmark for cancers. In this study, we utilized our free and open-source protein-ligand docking software, idock, prospectively to identify potential CDK2 inhibitors from 4,311 FDA-approved small molecule drugs using a repurposing strategy and an ensemble docking methodology. Sorted by average idock score, nine compounds were purchased and tested in vitro. Among them, the anti-psychotic drug fluspirilene exhibited the highest anti-proliferative effect in human hepatocellular carcinoma HepG2 and Huh7 cells. We demonstrated for the first time that fluspirilene treatment significantly increased the percentage of cells in G1 phase, and decreased the expressions of CDK2, cyclin E and Rb, as well as the phosphorylations of CDK2 on Thr160 and Rb on Ser795. We also examined the anti-cancer effect of fluspirilene in vivo in BALB/C nude mice subcutaneously xenografted with human hepatocellular carcinoma Huh7 cells. Our results showed that oral fluspirilene treatment significantly inhibited tumor growth. Fluspirilene (15 mg/kg exhibited strong anti-tumor activity, comparable to that of the leading cancer drug 5-fluorouracil (10 mg/kg. Moreover, the cocktail treatment with fluspirilene and 5-fluorouracil exhibited the highest therapeutic effect. These results suggested for the first time that fluspirilene is a potential CDK2 inhibitor and a candidate anti-cancer drug for the treatment of human hepatocellular carcinoma. In view of the fact that fluspirilene has a long history

    In order to promote consensus building on decommissioning operation rules for medical linear accelerators in Japan, we carried out a risk communication (RC) approach mainly providing knowledge for maintenance staff regarding induced radioactivity. In February 2012, we created a booklet (26 pages) to present an overview of the amended law, the mechanism and the distribution of induced radioactivity showing the actual radiation dose rate around a linear accelerator and actual exposure doses to staff. In addition, we co-sponsored a seminar for workers in this field organized by the Japan Medical Imaging and Radiological Systems Industries Association to explain the contents of this booklet, and answer questions regarding induced radioactivity of linear accelerators as an RC program. As a result, the understanding of staff regarding the regulations on maximum X-ray energy on linear accelerators (Papproach suggests that consensus building should be used to make rules on decommissioning operations for linear medical accelerators.

Aims To simultaneously examine effects of variant glutamate decarboxylase-like protein 1 (GADL1) and medication adherence on response to lithium maintenance treatment in Han Chinese patients with bipolar I (BPI) disorder. Method Frequencies of manic and depressive episodes between carriers and non-carriers of the effective GADL1 rs17026688 T allele during the cumulative periods of off-lithium, poor adherence to lithium treatment and good adherence to lithium treatment were compared in Han Chinese patients with BPI disorder (n=215). Results GADL1 rs17026688 T carriers had significantly lower frequencies of recurrent affective episodes than non-T carriers during the cumulative period of good adherence, but not during those of poor adherence. Conclusions GADL1 rs17026688 and medication adherence jointly predict response to lithium maintenance treatment in Han Chinese BPI patients. Declaration of interest None.

As a result, the understanding of staff regarding the regulations on maximum X-ray energy on linear accelerators (P<0.05), and the outline of clearance systems (P<0.01), were facilitated by RC. In addition, we found that about 70% of maintenance staff considered that the cooling time for decommissioning operation depended on the situation. Our RC approach suggests that consensus building should be used to make rules on decommissioning operations for linear medical accelerators. (author)

    BACKGROUND: In order to improve the delivery of health services for chronic medical conditions in our methadone clinic, we added an onsite health screening and brief health counseling to the treatment plans for patients receiving methadone maintenance treatment at the Atlanta Veterans Affairs Medical Center (VAMC). We then conducted a follow up retrospective chart review to assess whether this intervention improved health outcome for those patients. METHODS: We reviewed the charts of one hundred and two patients who received treatment at Atlanta VAMC methadone clinic between 2002 and 2008. We sought to determine whether our increased health education and screening intervention was associated with improved: 1) Improved drug addiction outcome (as measured by comparing percentage of opiate and cocaine positive drug screens from admission to most recent). 2) Basic health screening, (as measured by the patient's compliance with primary care physicians (PCP) appointments and current smoking status). 3) Management of co-occurring medical conditions (as measured by levels of LDL cholesterol, hemoglobin A1c, and systolic blood pressure (SBP). 4) Presence of QTc prolongation (difference in QTc between baseline and most recent EKG). RESULTS: Illicit drug use (opiate and cocaine) markedly decreased in patients overall. The effect was more robust for those successfully "retained" (n=55, pCompliance with PCP appointments was high (82% and 88% before and after the onsite intervention, respectively) for "retained" patients. LDL cholesterol level was within normal range for all patients. A1c improved by 40% after the onsite intervention as reflected by the decreased percentage of patients with A1c > 7 % from before to after the intervention (90% vs. 50%, p=0.05). However, the prevalence of uncontrolled hypertension did not significantly improve after the onsite intervention (38% vs. 28%, p=0.34).

    Cognitive behavioral therapy for adherence and depression (CBT-AD) in HIV improves both adherence and depression outcomes relative to enhanced treatment as usual (ETAU). However, in persons with injection drug use (PWIDU) histories, adherence gains seen during treatment have not been maintained postintervention. Therefore, we examined whether heroin or cocaine use at study entry moderated acquisition or maintenance of adherence gains after CBT-AD. HIV-positive adults in treatment for opioid dependence (n = 89) were randomly assigned to CBT-AD or ETAU and completed 3-, 6-, and 12-month assessments. Participants were majority male (61%), white (48%), and heterosexual (79%). Hierarchical linear modeling was used to evaluate whether heroin or cocaine use at baseline interacted with intervention assignment to predict change in adherence during active treatment and follow-up. CBT-AD-related improvement in adherence during the active intervention period did not vary by baseline substance use. However, cocaine use (but not heroin use) at baseline interacted with intervention assignment to predict a significant decline in follow-up adherence (cocaine use × group condition coefficient = -0.77, t = -2.44, p = 0.02) such that by 12 months, adherence among CBT participants was significantly lower among those who used cocaine (45.0%) compared to those who did not (72.3%; t = 2.50, p = 0.018). HIV-positive PWIDU who use heroin or cocaine at baseline can benefit from the CBT-AD intervention to improve adherence to antiretroviral therapy; therefore, providers should not withhold an active psychosocial treatment for HIV-positive PWIDU who are using. Cocaine use at baseline may limit the degree to which gains are maintained postintervention, and therefore, booster sessions may be needed. PMID:27158849

  13. Medical use of cannabis. Cannabidiol: a new light for schizophrenia?

    The medical properties of cannabis have been known for many centuries; its first documented use dates back to 2800 BC when it was described for its hallucinogenic and pain-relieving properties. In the first half of the twentieth century, a number of pharmaceutical companies marked cannabis for indications such as asthma and pain, but since then its use has sharply declined, mainly due to its unpredictable effects, but also for socio-political issues. Recently, great attention has been directed to the medical properties of phytocannabinoids present in the cannabis plant alongside the main constituent Δ⁹-Tetrahydrocannabinol (THC); these include cannabinoids such as cannabidiol (CBD), cannabigerol (CBG), and tetrahydrocannabivarin (THCV). Evidence suggests an association between cannabis and schizophrenia: schizophrenics show a higher use of marijuana as compared to the healthy population. Additionally, the use of marijuana can trigger psychotic episodes in schizophrenic patients, and this has been ascribed to THC. Given the need to reduce the side effects of marketed antipsychotics, and their weak efficacy on some schizophrenic symptoms, cannabinoids have been suggested as a possible alternative treatment for schizophrenia. CBD, a non-psychoactive constituent of the Cannabis sativa plant, has been receiving growing attention for its anti-psychotic-like properties. Evidence suggests that CBD can ameliorate positive and negative symptoms of schizophrenia. Behavioural and neurochemical models suggest that CBD has a pharmacological profile similar to that of atypical anti-psychotic drugs and a clinical trial reported that this cannabinoid is a well-tolerated alternative treatment for schizophrenia.

  19. SU-E-T-144: Effective Analysis of VMAT QA Generated Trajectory Log Files for Medical Accelerator Predictive Maintenance

    International Nuclear Information System (INIS)

    Purpose: To determine the effectiveness of SPC analysis for a model predictive maintenance process that uses accelerator generated parameter and performance data contained in trajectory log files. Methods: Each trajectory file is decoded and a total of 131 axes positions are recorded (collimator jaw position, gantry angle, each MLC, etc.). This raw data is processed and either axis positions are extracted at critical points during the delivery or positional change over time is used to determine axis velocity. The focus of our analysis is the accuracy, reproducibility and fidelity of each axis. A reference positional trace of the gantry and each MLC is used as a motion baseline for cross correlation (CC) analysis. A total of 494 parameters (482 MLC related) were analyzed using Individual and Moving Range (I/MR) charts. The chart limits were calculated using a hybrid technique that included the use of the standard 3σ limits and parameter/system specifications. Synthetic errors/changes were introduced to determine the initial effectiveness of I/MR charts in detecting relevant changes in operating parameters. The magnitude of the synthetic errors/changes was based on: TG-142 and published analysis of VMAT delivery accuracy. Results: All errors introduced were detected. Synthetic positional errors of 2mm for collimator jaw and MLC carriage exceeded the chart limits. Gantry speed and each MLC speed are analyzed at two different points in the delivery. Simulated Gantry speed error (0.2 deg/sec) and MLC speed error (0.1 cm/sec) exceeded the speed chart limits. Gantry position error of 0.2 deg was detected by the CC maximum value charts. The MLC position error of 0.1 cm was detected by the CC maximum value location charts for every MLC. Conclusion: SPC I/MR evaluation of trajectory log file parameters may be effective in providing an early warning of performance degradation or component failure for medical accelerator systems

    Fifty-five former opioid addicts who have been methadone maintained patients for 10 or more years and whose urine has tested negative for drugs for 2 or more years were compared to 99 former opioid addicts who have been medication-free for 10 or more years. Groups were comparable in age and education, but the medication-free subjects were younger when having started opioids with more severe addiction scores. Methadone maintained patients presented with a higher proportion of psychiatric comorbidity and chronic pain. Their scores of perceived sleep quality and cognitive state were poorer than the medication-free individuals. Possible explanations of the differences are discussed in this article.

    Full Text Available Abstract Background Opioid maintenance treatment (OMT has a positive impact on substance use and health outcomes among HIV-infected opioid dependent patients. The present study investigates non-medical use of opioids by HIV-infected opioid-dependent individuals treated with buprenorphine or methadone. Methods The MANIF 2000 study is a longitudinal study that enrolled a cohort of 476 HIV-infected opioid-dependent individuals. Data were collected in outpatient hospital services delivering HIV care in France. The sample comprised all patients receiving OMT (either methadone or buprenorphine who attended at least one follow-up visit with data on adherence to OMT (N = 235 patients, 1056 visits. Non-medical use of opioids during OMT was defined as having reported use of opioids in a non-medical context, and/or the misuse of the prescribed oral OMT by an inappropriate route of administration (injection or sniffing. After adjusting for the non-random assignment of OMT type, a model based on GEE was then used to identify predictors of non-medical use of opioids. Results Among the 235 patients, 144 (61.3% and 91 (38.9% patients were receiving buprenorphine and methadone, respectively, at baseline. Non-medical use of opioids was found in 41.6% of visits for 83% of individual patients. In the multivariate analysis, predictors of non-medical use of opioids were: cocaine, daily cannabis, and benzodiazepine use, experience of opioid withdrawal symptoms, and less time since OMT initiation. Conclusions Non-medical use of opioids was found to be comparable in OMT patients receiving methadone or buprenorphine. The presence of opioid withdrawal symptoms was a determinant of non-medical use of opioids and may serve as a clinical indicator of inadequate dosage, medication, or type of follow-up. Sustainability and continuity of care with adequate monitoring of withdrawal symptoms and polydrug use may contribute to reduced harms from ongoing non-medical use of opioids.

    As a part of a special collection in this issue of Academic Medicine, which is focused on mastery learning in medical education, this Perspective describes how the expert-performance approach with deliberate practice is consistent with many characteristics of mastery learning. Importantly, this Perspective also explains how the expert-performance approach provides a very different perspective on the acquisition of skill. Whereas traditional education with mastery learning focuses on having students attain an adequate level of performance that is based on goals set by the existing curricula, the expert-performance approach takes an empirical approach and first identifies the final goal of training-namely, reproducibly superior objective performance (superior patient outcomes) for individuals in particular medical specialties. Analyzing this superior complex performance reveals three types of mental representations that permit expert performers to plan, execute, and monitor their own performance. By reviewing research on medical performance and education, the author describes evidence for these representations and their development within the expert-performance framework. He uses the research to generate suggestions for improved training of medical students and professionals. Two strategies-designing learning environments with libraries of cases and creating opportunities for individualized teacher-guided training-should enable motivated individuals to acquire a full set of refined mental representations. Providing the right resources to support the expert-performance approach will allow such individuals to become self-regulated learners-that is, members of the medical community who have the tools to improve their own and their team members' performances throughout their entire professional careers.

    McErlain-Burns, T L; Thomson, R

    1999-08-01

    Concerns have been expressed repeatedly about the effectiveness of clinical audit. Some have argued that this is limited by the lack of integration within day-to-day practice and with other NHS policy initiatives. We aimed to explore what mechanisms were being used to develop annual clinical audit programmes within NHS Trusts, and to describe the influence of other initiatives on this; to understand how such influences are exerted; and to understand the role of key players, in order to inform future programme development. Semi-structured face-to-face interviews were performed with Chairs of Clinical Audit Committees, Clinical Audit Managers and Co-ordinators (N = 15) in the former Yorkshire Region of the NHS in England. Concerns about the development, planning and integration of clinical audit focused upon an almost exclusive medical dominance and upon how audit leadership could be delivered within the context of hospital management structures. The lack of an overall plan for the development of clinical audit in most sites was seen as enabling the doctors' agenda to dominate. Purchasing authorities were recognized as being important, but often with limited influence. Other influences on the audit agenda, such as research and development (R&D) and clinical risk management, were rarely well co-ordinated. These findings concur with previous studies in identifying a wide range of constraints on the progress of audit. Several of these constraints operate within the internal environment, for example the doctors' agenda, and concerns about management involvement. Such constraints require resolution in order to facilitate the integration of audit with other initiatives and to achieve the goals of audit effectively. Clinical effectiveness and clinical governance may offer a means of facilitating this integration. PMID:10461584

From securities report from 2000 to 2002 fiscal year, generation cost of NPP was calculated 8.3 Yen/kWh (capacity factor=78%) compared with 10.0 Yen/kWh (capacity factor=41%) of thermal power. Reduction or suppression of generation cost requested to reduce fuel and operation and maintenance cost or to increase power generation capacity. Increase of operating years and upgrade of capacity factor contributed to reduce generation cost and then aging measures for lifecycle extension of NPP was important as well as securing high capacity factor without failures or troubles of NPP with adequate maintenance action. Maintenance program was arranged to decide scope of inspection and repair and measures based on evaluated data. Use of risk information was recommended for reliable maintenance. Safety, quality assurance and schedule of maintenance work were supervised as well as radiation protection and occupational safety. (T. Tanaka)

  1. Preventive maintenance

    International Nuclear Information System (INIS)

    The information contained in this paper should be used in conjunction with the maintenance instructions provided by the manufacturer of each valve. When there is any question or conflict between the procedure described and the manufacturer's, the author suggests determining the best method for the applications. A good long range preventative maintenance program for valves will eliminate costly repairs or replacement of valves long before their time. A little flush, lube, and what was once called elbow grease will also go a long way in reducing your downtime and maintenance budget. This paper will discuss one of the most misunderstood theories concerning valve maintenance, i.e., that periodic maintenance of valves includes the injection of sealants. Sealants are injected into valves as a secondary seal for most valves. Under normal conditions, valves do not require sealant injection. Solid fillers in sealants tend to plug the system making it virtually impossible to inject either sealant or a lubricant, requiring the injection of flush or cleaners to dislodge the solids. Topics covered in this paper will range from general maintenance requirements to valve flushing, cleaning and lubrication

    Escalating medical costs have made it increasingly important to carry out economic evaluations of drug therapy. In the area of acid-related diseases, much of the current interest is focused on comparisons between omeprazole and H2 receptor antagonists. After having discussed the basic methodology used in these analyses, viz. the decision-tree analysis, this paper presents an extension of this methodology, the Markov chain approach, which is more appropriate for analyses of longer time periods. Thereafter, this methodology is used to analyze the cost-effectiveness of omeprazole in intermittent versus maintenance treatment of reflux esophagitis. The cost data are from Sweden and the time period studied is one year. It is found that maintenance treatment provides 63 more healthy days per year at an extra direct cost of SEK 40 per day. From a sensitivity analysis it is concluded that the cost-effectiveness of intermittent versus maintenance treatment is mainly determined by the probability of relapse when off treatment, the severity of the symptoms in the case of a relapse and the value to the patient of a healthy day, i.e. a day free from reflux esophagitis.

    A maintenance program generated through the consideration of characteristics and failures of medical equipment is an important component of technology management. However, older technology devices and newer high-tech devices cannot be efficiently managed using the same strategies because of their different characteristics. This study aimed to generate a maintenance program comprising two different strategies to increase the efficiency of device management: preventive maintenance for older technology devices and predictive maintenance for newer high-tech devices. For preventive maintenance development, 589 older technology devices were subjected to performance verification and safety testing (PVST). For predictive maintenance development, the manufacturers' recommendations were used for 134 high-tech devices. These strategies were evaluated in terms of device reliability. This study recommends the use of two different maintenance strategies for old and new devices at hospitals in developing countries. Thus, older technology devices that applied only corrective maintenance will be included in maintenance like high-tech devices. PMID:27195666

    Full Text Available Although medical equipment maintenance has been carefully managed for years, very few in-depth studies have been conducted to evaluate the effectiveness and efficiency of these implemented preventive maintenance strategies, especially after the debate about the credibility of manufacturer’s recommendations has increased in the clinical engineering community. Facing the dilemma of merely following manufactures maintenance manual or establishing an evidence-based maintenance, medical equipment maintenance could have exploited an advanced area in operations research which is maintenance optimization research. In this paper, we review and examine carefully the status of application oriented research on preventive maintenance optimization of medical devices. This study addresses preventive healthcare maintenance with a focus on factors influencing the maintenance decision making. The analysis is structured by defining different aspects necessary to construct a maintenance optimization model. We conclusively propose directions to develop suitable tools for better healthcare maintenance management.

    Full Text Available Following Food and Drug Administration (FDA approval, many drugs are prescribed for non-FDA-approved ("off-label" uses. If substantial evidence supports the efficacy and safety of off-label indications, manufacturers can pursue formal FDA approval through supplemental new drug applications (sNDAs. We evaluated the effect of FDA determinations on pediatric sNDAs for antipsychotic drugs on prescribing of these products in children.Retrospective, segmented time-series analysis using new prescription claims during 2003-2012 for three atypical antipsychotics (olanzapine, quetiapine, ziprasidone. FDA approved the sNDAs for pediatric use of olanzapine and quetiapine in December 2009, but did not approve the sNDA for pediatric use of ziprasidone.During the months before FDA approval of its pediatric sNDA, new prescriptions of olanzapine decreased for both children and adults. After FDA approval, the increase in prescribing trends was similar for both age groups (P = 0.47 for schizophrenia and bipolar disorder; P = 0.37 for other indications. Comparable decreases in use of quetiapine were observed between pediatrics and adults following FDA approval of its pediatric sNDA (P = 0.88; P = 0.63. Prescribing of ziprasidone decreased similarly for pediatric and adult patients after FDA non-approval of its pediatric sNDA (P = 0.61; P = 0.79.The FDA's sNDA determinations relating to use of antipsychotics in children did not result in changes in use that favored the approved sNDAs and disfavored the unapproved sNDA. Improved communication may help translate the agency's expert judgments to clinical practice.

  10. Maintenance management systems

    International Nuclear Information System (INIS)

    This paper is concerned principally with Maintenance Management systems and their effective introduction into organisations. Maintenance improvement is basically a problem of managing the maintenance department in the broadest sense. Improvement does not only lie in the area of special techniques, systems or procedures; although they are valuable tools, but rather in a balanced attack, carefully guided by management. Over recent years, maintenance systems have received the major emphasis and in many instances the selection of the system has become a pre-occupation, whereas the importance of each maintenance function must be recognised and good management practices applied to all maintenance activities. The ingredients for success in the implementation of maintenance management systems are summarised as: having a management committee, clear objectives, project approach using project management techniques and an enthusiastic leader, user managed and data processing supported project, realistic budget and an understanding of the financial audit requirements.

    Full Text Available Background and Objectives: Metabolic syndrome (visceral obesity, dyslipidaemia, hyperglycaemia, hypertension is a substantial public health problem, especially amongst individuals receiving antipsychotic medication. Methods: We studied routine screening practices for metabolic syndrome amongst psychiatry outpatients receiving injected depot anti-psychotic medication at a clinic in Dublin, Ireland. Results: Our initial audit (n = 64 demonstrated variable levels of documentation of criteria for metabolic syndrome in outpatient files; e.g. weight was recorded in 1.6% of files, serum high density lipoprotein in 12.5%. As our intervention, we introduced a screening check-list comprising risk factors and criteria for metabolic syndrome, based on the definition of the International Diabetes Federation. Re-audit (n = 54 demonstrated significantly improved levels of documentation; e.g. weight was recorded in 61.1% of files. Notwithstanding these improvements, only 11 (20.4% of 54 patient files examined in the re-audit, contained sufficient information to determine whether or not the patient fulfilled criteria for metabolic syndrome; of these, 3 patients (27.3% fulfilled criteria for metabolic syndrome. There was, however, significant additional morbidity in relation to individual criteria (waist circumference, serum triglyceride level, systolic blood pressure and serum fasting glucose. Conclusions: We recommend enhanced attention be paid to metabolic morbidity in this patient group.

    The performance and competitiveness of manufacturing companies is dependent on the availability, reliability and productivity of their production facilities. Low productivity, downtime, and poor machine performance is often linked to inadequate plant maintenance, which in turn can lead to reduced production levels, increasing costs, lost market opportunities, and lower profits. These pressures have given firms worldwide the motivation to explore and embrace proactive maintenance strategies over the traditional reactive firefighting methods. The traditional view of maintenance has shifted into one of an overall view that encompasses Overall Equipment Efficiency, Stakeholders Management and Life Cycle assessment. From practical point of view it requires changes in approach to maintenance represented by managers and changes in actions performed within maintenance area. Managers have to understand that maintenance is not only about repairs and conservations of machines and devices, but also actions striving for more efficient resources management and care for safety and health of employees. The purpose of the work is to present strategic analysis based on SWOT analysis to identify the opportunities and strengths of maintenance process, to benefit from them as much as possible, as well as to identify weaknesses and threats, so that they could be eliminated or minimized.

    2008-01-01

    Malaysia has a long history of medical education, with Singapore becoming the first medical school to serve the region after its foundation in 1905. The first school to be established in Kuala Lumpur after independence from the British was the Faculty of Medicine at the University of Malaya in 1963. Whilst today there are 21 public and private medical schools, all offering a 5 year undergraduate programme, some private schools have diversified by developing international collaboration and conduct twinning or credit-transfer programmes. All medical schools require accreditation by the National Accreditation Board and the Malaysian Medical Council. Although the criteria for accreditation is comprehensive and covers a broad range of areas of assessment, it is debatable whether it always matches the needs of the country. The dramatic increase in medical schools in the last two decades has posed challenges in terms of maintenance of quality, physical infrastructure and suitably qualified faculty.

  5. Advances in safety related maintenance

    International Nuclear Information System (INIS)

    The maintenance of systems, structures and components in nuclear power plants (NPPs) plays an important role in assuring their safe and reliable operation. Worldwide, NPP maintenance managers are seeking to reduce overall maintenance costs while maintaining or improving the levels of safety and reliability. Thus, the issue of NPP maintenance is one of the most challenging aspects of nuclear power generation. There is a direct relation between safety and maintenance. While maintenance alone (apart from modifications) will not make a plant safer than its original design, deficient maintenance may result in either an increased number of transients and challenges to safety systems or reduced reliability and availability of safety systems. The confidence that NPP structures, systems and components will function as designed is ultimately based on programmes which monitor both their reliability and availability to perform their intended safety function. Because of this, approaches to monitor the effectiveness of maintenance are also necessary. An effective maintenance programme ensures that there is a balance between the improvement in component reliability to be achieved and the loss of component function due to maintenance downtime. This implies that the safety level of an NPP should not be adversely affected by maintenance performed during operation. The nuclear industry widely acknowledges the importance of maintenance in NPP safety and operation and therefore devotes great efforts to develop techniques, methods and tools to aid in maintenance planning, follow-up and optimization, and in assuring the effectiveness of maintenance

  6. Maintenance in sustainable manufacturing

    2014-09-01

    Full Text Available Background: Sustainable development is about reaching a balance between economic, social, and environmental goals, as well as people's participation in the planning process in order to gain their input and support. For a company, sustainable development means adoption of such business strategy and actions that contribute to satisfying present needs of company and stakeholders, as well as simultaneous protection, maintenance and strengthening of human and environmental potential which will be needed in the future. This new approach forces manufacturing companies to change their previous management paradigms. New management paradigm should include new issues and develop innovative methods, practices and technologies striving for solving problem of shortages of resources, softening environment overload and enabling development of environment-friendly lifecycle of products. Hence, its realization requires updating existing production models as they are based on previously accepted paradigm of unlimited resources and unlimited regeneration capabilities. Maintenance plays a crucial role because of its impact on availability, reliability, quality and life cycle cost, thus it should be one of the main pillars of new business running model.  Material and methods: The following paper is a result of research on the literature and observation of practices undertaken by a company within maintenance area. Results and conclusions: The main message is that considering sustainable manufacturing requires considerable expanding range of analysis and focusing on supporting processes. Maintenance offers numerous opportunities of decreasing influence of business processes on natural environment and more efficient resources utilization. The goal of maintenance processes realizing sustainable development strategy is increased profitability of exploitation and optimization of total lifecycle cost without disturbing safety and environmental issues.

    Full Text Available In high-rise residential buildings, the quality of facilities management services is significant to the normal operation of the facilities. Unfortunately, lack of concern towards building maintenance, especially preventive maintenance, happens in domestic housing industry in Malaysia. Majority of the maintenance operations of condominiums suffer from lack of planning, lack of proactive maintenance plan, and lack of proper implementation. Thus, this paper reviews the implementation of preventive maintenance strategy, routine maintenance in specific. An extensive review of literature published in 1987 to 2014 is performed for the purpose of this research. The publications are sourced from journal articles, conference proceedings and books. The literature analysis confirms that the routine maintenance of facilities and building services is vital and it can be influential towards the maintenance performance. Subsequently, a theoretical framework is developed, which shows the relationship between routine maintenance of building facilities & services and maintenance performance. The building facilities & services are divided into two categories. They are essential facilities & services that ensure the safety, health, habitability, and operability of buildings; while value-added facilities & services deal with property value, return on investment, and quality living of buildings. Based on the findings, a future research is proposed, which aims to identify the appropriate routine of maintenance for the facilities and services in high-rise residential buildings to improve the maintenance performance.

  15. Reducing maintenance costs

    International Nuclear Information System (INIS)

    The increasingly more expensive maintenance measures, cuts in the cost budget, and the loss of know-how on the part of vendors all require a change of policy with respect to maintenance concepts of the part of operators. This also applies to the existing valve concepts, the drives included. Under these aspects, the current drive, which is self-actuated and actuated by outside media, for a parallel-plate valve of a nomial width of 700 was reconsidered. The effort served to reduce maintenance costs and, at the same time, simplify the drive concept as well as cut back on the number of in-service inspections. Moreover, the number of active components were to be minimized and installation conditions in the plant were to be improved. When the boundary conditions to be observed with respect to process technology had been laid down, the competent technical department developed a concept of modification of the drive. A major constituent part was the demonstration of the functioning capability of the new drive under accident conditions. It was achieved mainly by an analytical approach. In the resultant drive concept, the same control valves are employed to actuate a driving cylinder by means of self-actuation or by an outside medium as a function of pressure. (orig.)

  2. Towards automated traceability maintenance.

    Science.gov (United States)

    Mäder, Patrick; Gotel, Orlena

    2012-10-01

    Traceability relations support stakeholders in understanding the dependencies between artifacts created during the development of a software system and thus enable many development-related tasks. To ensure that the anticipated benefits of these tasks can be realized, it is necessary to have an up-to-date set of traceability relations between the established artifacts. This goal requires the creation of traceability relations during the initial development process. Furthermore, the goal also requires the maintenance of traceability relations over time as the software system evolves in order to prevent their decay. In this paper, an approach is discussed that supports the (semi-) automated update of traceability relations between requirements, analysis and design models of software systems expressed in the UML. This is made possible by analyzing change events that have been captured while working within a third-party UML modeling tool. Within the captured flow of events, development activities comprised of several events are recognized. These are matched with predefined rules that direct the update of impacted traceability relations. The overall approach is supported by a prototype tool and empirical results on the effectiveness of tool-supported traceability maintenance are provided. PMID:23471308

  3. Remote maintenance monitoring system

    Simpkins, Lorenz G. (Inventor); Owens, Richard C. (Inventor); Rochette, Donn A. (Inventor)

    1992-01-01

    A remote maintenance monitoring system retrofits to a given hardware device with a sensor implant which gathers and captures failure data from the hardware device, without interfering with its operation. Failure data is continuously obtained from predetermined critical points within the hardware device, and is analyzed with a diagnostic expert system, which isolates failure origin to a particular component within the hardware device. For example, monitoring of a computer-based device may include monitoring of parity error data therefrom, as well as monitoring power supply fluctuations therein, so that parity error and power supply anomaly data may be used to trace the failure origin to a particular plane or power supply within the computer-based device. A plurality of sensor implants may be rerofit to corresponding plural devices comprising a distributed large-scale system. Transparent interface of the sensors to the devices precludes operative interference with the distributed network. Retrofit capability of the sensors permits monitoring of even older devices having no built-in testing technology. Continuous real time monitoring of a distributed network of such devices, coupled with diagnostic expert system analysis thereof, permits capture and analysis of even intermittent failures, thereby facilitating maintenance of the monitored large-scale system.

    The product of the project, e-Famemain, is a new kind of tool for benchmarking, which is based on many years' research efforts within Finnish industry. It helps to evaluate plants' performance in operations and maintenance by making industrial plants comparable with the aid of statistical methods. The system is updated continually and automatically. It carries out automatically multivariate statistical analysis when data is entered into system, and many other statistical operations. Many studies within Finnish industry during the last ten years have revealed clear causalities between various performance indicators. In addition, these causalities should be taken into account when utilising benchmarking or forecasting indicator values e.g. for new investments. The benchmarking system consists of five sections: data input section, positioning section, locating differences section, best practices and planning section and finally statistical tables. (orig.)

  11. Cofrentes maintenance. Life essence

    International Nuclear Information System (INIS)

    Even though it may seem like something much more complex, maintenance is not more than the seed of continuity, the alchemy of eternal youth or the key to combating the cruel passage of time that haunts us all. Little does it matter where you are from or where you are going; it is irrelevant whether you are man, woman or machine. If you do not have a more or less sensible strategy of survival, reality can take you by surprise, without prior warning, at the wrong place and the wrong time. It is sad to see how what we thought was eternal, and thus do not care for and pamper as we should, eventually loses its qualities and functions over the years and fades away like a vague memory.

  16. Entretian Model for Software Maintenance

    Directory of Open Access Journals (Sweden)

    Priya K Betala

    2013-10-01

    Full Text Available Maintenance refers to the act of modifying the software after putting in use in order to maintain its usability.[1]. In other words, Software maintenance can be defined as; it is the process of providing services to the customers after the delivery of the software. Despite the fact that maintaining software is very challenging, it is the most important routine that must be carried out in the development cycle. If the software is not maintained efficiently it may lead to the death of the software. Maintenance of software may be carried out in two ways. The first one is called „In-house maintenance‟ and the second one is called „Transition maintenance‟. The latter faces the drastic challenges when compared to former, as one team may not provide complete source code to the other, leading to unstructured code, lack of appropriate technique and knowledge about the functioning of the current software. There are a few aspects of software maintenance that set it apart from the other phases. Software maintenance cost comprises more than half of the total software development cost. Also, without software maintenance, it is impossible to change the problems within the product after its release, and many disasters can happen because of immature software. Recognising the importance of software maintenance, this paper proposes a model called “ENTRETIAN MODEL” (Entretian, a French word meaning Maintenance which consists of six basic steps to follow while maintaining software system. This model overcomes certain misconceptions about maintenance phase and it is highly beneficial to the Maintenance Support Team (MST to handle their maintenance activities systematically and efficiently. By employing the proposed model, the MST is able to overcome the technical and managerial issues that are faced earlier in the maintenance phase. The advantage of using “Entretian Model” is best illustrated in this paper with the help of the ERP package.

    Full Text Available The issue of public hospitals buildings’ maintenance in Palestine is regarded as a challenging issue. The lack of attention to maintenance management in hospitals has led to deterioration of buildings and reduced the health care services. The aim of this paper is to assess the current practice of maintenance process and management in public hospitals buildings in the Gaza Strip. A questionnaire survey that distributed to 13 public hospitals, which are administered by the Ministry of Health (MoH in the Gaza Strip, was used to collect the primary data for this study. The results of this study present an overview of the current situation of the maintenance process in public hospitals buildings in the Gaza Strip. The findings indicated that while the corrective maintenance is implemented in all the 13 public hospitals, preventive maintenance is employed along with corrective maintenance, only in three hospitals. In addition, the findings indicated variances in responding to maintenance requests, while 50% of the maintenance departments took few hours to respond to maintenance requests, the rest took a few days to respond, this can be explained due to lack of spare parts and qualified staff. The study showed also that there is a shortage in training the hospital facility’s users on how to report maintenance problems. The results of this study indicated that most hospitals in the Gaza Strip have no maintenance plan for medical equipment; they do not have quality control system for repair and preventive maintenance. It is recommended to employ experience maintenance staff in order to prepare adequate maintenance plan and detailed check list, which is required for preventive maintenance. The MoH should organize specialized training courses in maintenance management for their staff in order to improve their effectiveness and efficiency. Hospitals in Gaza should make sure that all spare parts available in their storages for immediate action when

Maintenance crews will be brought to the orbital worksite to make repairs and replace scientific instruments. For major overhauls the telescope can be temporarily returned to earth with the aid of the Shuttle. It will, thus, be possible to conduct astronomical studies with the ST for two decades or more. The five first-generation scientific instruments used with the ST include a wide field/planetary camera, a faint object camera, a faint object spectrograph, a high resolution spectrograph, and a high speed photometer. Attention is given to the optical telescope assembly, the support systems module, aspects of mission and science operations, unscheduled maintenance, contingency orbital maintenance, planned on-orbit maintenance, ground maintenance, ground refurbishment, and ground logistics.

  13. Robots for Aircraft Maintenance

    Science.gov (United States)

    1993-01-01

    Marshall Space Flight Center charged USBI (now Pratt & Whitney) with the task of developing an advanced stripping system based on hydroblasting to strip paint and thermal protection material from Space Shuttle solid rocket boosters. A robot, mounted on a transportable platform, controls the waterjet angle, water pressure and flow rate. This technology, now known as ARMS, has found commercial applications in the removal of coatings from jet engine components. The system is significantly faster than manual procedures and uses only minimal labor. Because the amount of "substrate" lost is minimal, the life of the component is extended. The need for toxic chemicals is reduced, as is waste disposal and human protection equipment. Users of the ARMS work cell include Delta Air Lines and the Air Force, which later contracted with USBI for development of a Large Aircraft Paint Stripping system (LARPS). LARPS' advantages are similar to ARMS, and it has enormous potential in military and civil aircraft maintenance. The technology may also be adapted to aircraft painting, aircraft inspection techniques and paint stripping of large objects like ships and railcars.

    Living human cells require attachment to a suitable surface and special culture conditions in order to grow. These requirements are modified and amplified when cells are taken into a weightless environment. Special handling and maintenance systems are required for routine laboratory procedures conducted in the Orbiter and in the Spacelab. Methods were developed to maintain cells in special incubators designed for the Orbiter middeck, however, electrophoresis and other experiments require cells to be harvested off of the culture substrate before they can be processed or used. The cell transport assembly (CTA) was flown on STS-8, and results show that improvements are required to maintain adequate numbers of cells in this device longer than 48 hours. The life sciences middeck centrifuge probably can be used, but modifications will be required to transfer cells from the CTA and keep the cells sterile. Automated systems such as the Skylab SO-15 flight hardware and crew operated systems are being evaluated for use on the Space Shuttle, Spacelab, and Space Station research modules.

  15. Maintenance of nuclear power plants

    International Nuclear Information System (INIS)

    This Safety Guide provides detailed guidance on the provisions of the Code on the Safety in Nuclear Power Plants: Operation, IAEA Safety Series No. 50-C-O(Rev.1) on the maintenance of structures, systems and components. Like the Code, the Guide forms part of the IAEA's programme, referred to as the NUSS programme, for establishing Codes and Safety Guides relating to nuclear power plants. Effective maintenance is essential for safe operation of a nuclear power plant. It not only ensures that the level of reliability and effectiveness of all plant structures, systems and components having a bearing on safety remains in accordance with design assumptions and intent, but also that the safety status of the plant is not adversely affected after commencement of operation. Nuclear power plant maintenance requires special attention because of: Limitations set by requirements that a minimum number of components remain operable even when the plant is shut down in order to ensure that all necessary safety functions are guaranteed; Difficulty of access to some plant items even when the plant is shut down, due to radiation protection constraints; Potential radiological hazards to site personnel and the public. This Guide covers the organizational and procedural aspects of maintenance but does not give detailed technical advice on the maintenance of particular plant items. It gives guidance on preventive and remedial measures necessary to ensure that all structures, systems and components important to safety are capable of performing as intended.

  17. Pharmacological maintenance treatments of opiate addiction.

    Science.gov (United States)

    Bell, James

    2014-02-01

    For people seeking treatment, the course of heroin addiction tends to be chronic and relapsing, and longer duration of treatment is associated with better outcomes. Heroin addiction is strongly associated with deviant behaviour and crime, and the objectives in treating heroin addiction have been a blend of humane support, rehabilitation, public health intervention and crime control. Reduction in street heroin use is the foundation on which all these outcomes are based. The pharmacological basis of maintenance treatment of dependent individuals is to minimize withdrawal symptoms and attenuate the reinforcing effects of street heroin, leading to reduction or cessation of street heroin use. Opioid maintenance treatment can be moderately effective in suppressing heroin use, although deviations from evidence-based approaches, particularly the use of suboptimal doses, have meant that treatment as delivered in practice may have resulted in poorer outcomes than predicted by research. Methadone treatment has been 'programmatic', with a one-size-fits-all approach that in part reflects the perceived need to impose discipline on deviant individuals. However, differences in pharmacokinetics and in side-effects mean that many patients do not respond optimally to methadone. Injectable diamorphine (heroin) provides a more reinforcing medication for some 'nonresponders' and can be a valuable option in the rehabilitation of demoralized, socially excluded individuals. Buprenorphine, a partial agonist, is a less reinforcing medication with different side-effects and less risk of overdose. Not only is it a different medication, but also it can be used in a different paradigm of treatment, office-based opioid treatment, with less structure and offering greater patient autonomy.

All models presented so far have been in use in Air Forces, so that the advantages and disadvantages of different models are known. First it shows the current model of aircraft maintenance as well as its basic characteristics. Then the paper discusses two organizational models of aircraft maintenance with their advantages and disadvantages. The advantages and disadvantages of different models are analyzed based on the criteria of operational capabilities of military units. In addition to operational capabilities, the paper presents some other criteria which should be taken into account in the evaluation and selection of an optimal model of aircraft maintenance. Performing a qualitative analysis of some models may not be sufficient for evaluating the optimum choice for models of maintenance referring to the selected set of criteria from the scope of operational capabilities. In order to choose the optimum model, it is necessary to conduct a detailed economic and technical analysis of individual tactical model maintenance. A high-quality aircraft maintenance organization requires the highest state and army authorities to be involved. It is necessary to set clear objectives for all the elements of modern air force technical support programs based on the given evaluation criteria.

  20. Operational Interventions to Maintenance Error

    1997-01-01

    A significant proportion of aviation accidents and incidents are known to be tied to human error. However, research of flight operational errors has shown that so-called pilot error often involves a variety of human factors issues and not a simple lack of individual technical skills. In aircraft maintenance operations, there is similar concern that maintenance errors which may lead to incidents and accidents are related to a large variety of human factors issues. Although maintenance error data and research are limited, industry initiatives involving human factors training in maintenance have become increasingly accepted as one type of maintenance error intervention. Conscientious efforts have been made in re-inventing the team7 concept for maintenance operations and in tailoring programs to fit the needs of technical opeRAtions. Nevertheless, there remains a dual challenge: 1) to develop human factors interventions which are directly supported by reliable human error data, and 2) to integrate human factors concepts into the procedures and practices of everyday technical tasks. In this paper, we describe several varieties of human factors interventions and focus on two specific alternatives which target problems related to procedures and practices; namely, 1) structured on-the-job training and 2) procedure re-design. We hope to demonstrate that the key to leveraging the impact of these solutions comes from focused interventions; that is, interventions which are derived from a clear understanding of specific maintenance errors, their operational context and human factors components.

    Some trials have demonstrated the benefits of maintenance chemotherapy for advanced colorectal cancer. In chemotherapeutic strategies for advanced colorectal cancer, chemotherapy-related toxicity prevention and quality of life(QOL)maintenance are more important than the introduction of a strong regimen, especially when additional surgery is not possible. In Japan, the combination of a folinic acid/5-fluorouracil/oxaliplatin(FOLFOX)regimen and bevacizumab is a popular first-line chemotherapy regimen. However, despite its effectiveness, neuropathy or hand-foot syndrome after 5 or 6 cycles tends to lead to chemotherapy withdrawal. CAIRO3 trial reported the effectiveness of capecitabine and bevacizumab as a maintenance chemotherapy regimen. Additionally, the ML18147 trial demonstrated that bevacizumab beyond progression(BBP)prolonged overall survival(OS)and progression free survival(PFS)in patients with advanced colorectal cancer. Although those trials demonstrated the effectiveness of continuous or maintenance bevacizumab administration, no trials have compared the effectiveness of cytotoxic drugs with bevacizumab as maintenance therapies. Moreover, controversy exists regarding the selection of drugs as a maintenance therapy and the identification of patients who would benefit from maintenance therapy. PMID:25132024

  7. Maintenance training - who needs it?

    International Nuclear Information System (INIS)

    The author's job responsibilities at Rocky Flats include preventive maintenance, training to meet the needs of maintenance personnel, training for special projects such as welding and metal fabrication, and reporting to the manager of plant maintenance engineers. He notes that many old-line manufacturers are becoming high-tech companies, emphasizing the role of automation in production and quality control. He lists and discusses changes at Rocky Flats, along with the attendant preventive maintenance program the changes necessitate. He observes estimates that training costs to companies over the next 10 years will exceed 10% of their revenues - that in 1986, American companies spent $210 billion on training at all levels. But, if you think training is expensive, try placing a cost on ignorance. 9 figures

  9. Maintenance of nuclear power plant

    International Nuclear Information System (INIS)

    Maintenance action of nuclear power plant (NPP) was described. Maintenance of NPP aimed at assurance of required function of NPP's equipment so as to prevent release of radioactive materials into the environment as well as attainment of stable operation of NPP. Philosophy of NPP safety was based on defense-in-depth or multiple barriers requiring specified function for the equipment. Preventive maintenance was essential to NPP's equipment and the scope of maintenance was decided on priority with adequate method and frequency of inspection. Most inspection was conducted during periodic inspection at outage. Repair or improvement works were performed if needed. Periodic inspection period was very long and then capacity factor of NPP was low in Japan compared with foreign data although frequency of unscheduled shutdown was very low. Introduction of reability- centered maintenance was requested based on past experiences of overhaul inspection. Technical evaluation of aged NPP had been conducted on aging phenomena and promotion of advanced maintenance was more needed. (T. Tanaka)

  11. Dynamic grouping maintenance with time limited opportunities

    International Nuclear Information System (INIS)

    This paper presents firstly a dynamic grouping maintenance strategy for multi-component systems with positive economic dependence, which implies that combining maintenance activities is cheaper than performing maintenance on components separately. Preventive maintenance durations and multiple occurrences of maintenance activities within scheduling horizon are considered. Moreover, in a dynamic context, maintenance opportunities, defined as inactivity periods of the systems at which several maintenance activities could be executed with reduced maintenance costs, may randomly occur with time. The second objective of the paper is to propose a new algorithm to optimally update online the grouped maintenance planning by taking into account the maintenance opportunities. A numerical example of a five components system is finally introduced to illustrate the proposed dynamic grouping maintenance strategy

  13. Maintenance proficiency evaluation test bank

    International Nuclear Information System (INIS)

    The Maintenance Proficiency Evaluation Test Bank (MPETB) is an Electric Power Research Institute- (EPRJ-) operated, utility-sponsored means of developing, maintaining, and disseminating secure, high-quality written and performance maintenance proficiency tests. EPRTs charter is to ensure that all tests and test items that go into the Test Bank have been validated, screened for reliability, and evaluated to high standards of psychometric excellence. Proficiency tests of maintenance personnel.(mechanics, electricians, and instrumentation and control [I and C] technicians) are most often used to determine if an experienced employee is capable of performing maintenance tasks without further training. Such tests provide objective evidence for decisions to exempt an employee from what, for the employee, is unnecessary training. This leads to considerable savings in training costs and increased productivity because supervisors can assign personnel to tasks at which their competence is proven. The ultimate objective of proficiency evaluation is to ensure that qualified maintenance personnel are available to meet the maintenance requirements of the plant Numerous task-specific MPE tests (both written and performance) have been developed and validated using the EPRI MPE methodology by the utilities participating in the MPETB project A task-specific MPE consists of a multiple-choice written examination and a multi-step performance evaluation that can be used to assess an individual's present knowledge and skill level for a given maintenance task. The MPETB contains MPEs and test items for the mechanical, electrical, and I and C classifications that are readily available to participating utilities. Presently, utilities are placing emphasis on developing MPEs to evaluate outage-related maintenance tasks that demonstrate the competency and qualifications of plant and contractor personnel before the start of outage work. Utilities are also using the MPE methodology and process to

  14. Knowledge engineering thinking of maintenance

    International Nuclear Information System (INIS)

    Maintenance optimization problem could not always settled mathematically and was obliged to use quasi-optimum solution with omitting non-formulated limiting condition or neglecting part of optimization object. In such a case knowledge engineering thinking was encouraged. Maintenance of complicated plant and artificial system should be considered from artificial object (equipment/facility hardware and system), technical information and knowledge base, and organizational and human aspect or society and institution. Comprehensive management system in organization and society was necessary not only for assuring integrity of equipment but also for attaining higher performance, reliability and economics of system. For better judgment it was important to share mechanism to make use of more information with organization or whole society. It was required to create database and data mining for knowledge base management system of maintenance. Maintenance was called 'last fortress' to assure quality such as reliability and safety of required function of equipment. Strategic approach to develop maintenance technology under cooperation was considered. Life extension R and D road map was launched in 2005. (T. Tanaka)

  15. TPX remote maintenance and shielding

    International Nuclear Information System (INIS)

    The Tokamak Physics Experiment machine design incorporates comprehensive planning for efficient and safe component maintenance. Three programmatic decisions have been made to insure the successful implementation of this objective. First, the tokamak incorporates radiation shielding to reduce activation of components and limit the dose rate to personnel working on the outside of the machine. This allows most of the ex-vessel equipment to be maintained through conventional ''hands-on'' procedures. Second, to the maximum extent possible, low activation materials will be used inside the shielding volume. This resulted in the selection of Titanium (Ti-6Al-4V) for the vacuum vessel and PFC structures. The third decision stipulated that the primary in-vessel components will be replaced or repaired via remote maintenance tools specifically provided for the task. The component designers have been given the responsibility of incorporating maintenance design and for proving the maintainability of the design concepts in full-scale mockup tests prior to the initiation of final fabrication. Remote maintenance of the TPX machine is facilitated by general purpose tools provided by a special purpose design team. Major tools will include an in-vessel transporter, a vessel transfer system and a large component transfer container. In addition, tools such as manipulators and remotely operable impact wrenches will be made available to the component designers by this group. Maintenance systems will also provide the necessary controls for this equipment

    Jimenez, Jesus A.; Quintana, Rolando

    2000-10-01

    The objective of this research was to develop a decision support system (DSS) to study the impact of introducing new equipment into a medical apparel plant from a maintenance organizational structure perspective. This system will enable the company to determine if their capacity is sufficient to meet current maintenance challenges. The DSS contains two database sets that describe equipment and maintenance resource profiles. The equipment profile specifies data such as mean time to failures, mean time to repairs, and minimum mechanic skill level required to fix each machine group. Similarly, maintenance-resource profile reports information about the mechanic staff, such as number and type of certifications received, education level, and experience. The DSS will then use this information to minimize machine downtime by assigning the highest skilled mechanics to machines with higher complexity and product value. A modified version of the simplex method, the transportation problem, was used to perform the optimization. The DSS was built using the Visual Basic for Applications (VBA) language contained in the Microsoft Excel environment. A case study was developed from current existing data. The analysis consisted of forty-two machine groups and six mechanic categories with ten skill levels. Results showed that only 56% of the mechanic workforce was utilized. Thus, the company had available resources for meeting future maintenance requirements.

  15. Maintenance as a safety issue.

    Science.gov (United States)

    White, Jim

    2008-11-01

    Because safety is related to electrical power systems maintenance, it seems reasonable to assume there could be legal issues if maintenance is not performed. OSHA has not yet taken the stand that not performing maintenance as required by the manufacturer, NFPA 70B, or ANSI/NETA MTS-07 constitutes a willful violation. OSHA defines a willful citation as one where: "the employer knowingly commits with plain indifference to the law. The employer either knows that what he or she is doing constitutes a violation, or is aware that a hazardous condition existed and made no reasonable effort to eliminate it". However, NFPA 70E 2009 requires this maintenance, and OSHA has stated on its Web site that NFPA 70E is "a guide for meeting the requirements of the OSHA electrical regulations". In addition, federal courts have found that NFPA 70E is "standard industry practice." Once a company receives and accepts a willful citation, especially if received as the result of an accident investigation, its worker's compensation protection no longer shields it. One definition given by a trial attorney for a willful citation was that it is equal to negligent behavior. Be smart: Maintain that equipment and save yourself major problems, including unscheduled shutdowns and possible litigation.

    Health maintenance (HM) practices are essential to prevent illness, promote well-being, and maximize health. Patients with multiple myeloma (MM) are at increased risk for cardiovascular disease and cancers, yet, research on HM practices and preventative care of MM survivors has limited report. The study comprised a descriptive, correlational, and cross-sectional online survey design. Survey of patients with MM was carried out through the International Myeloma Foundation (IMF) and the Association of Cancer Online Resources (ACOR) e-mail list services. The members of the IMF and ACOR e-mail list services were surveyed, of which 237 patients responded. The modified Medical Expenditure Preventive Survey-Preventive Care questionnaire was used; it included items that ask patients regarding their healthcare practices that relate to dental care, cancer prevention, addiction, lifestyles, sensory screening, immunizations, cardiovascular, endocrine, psychosocial, and bone health. Descriptive statistics, Pearson's chi-square, and Spearman's rho correlation coefficient were obtained. In this study, men had statistically significant inferior global health maintenance scores than women (P = 0.002). Being employed (P = 0.054) and married or partnered (P = 0.017) were significantly correlated with better health maintenance patterns among male respondents. In contrast, no statistically significant correlations between sociodemographic factors and health maintenance patterns were found in women. Patients with MM, particularly men, require continued education and close monitoring of health maintenance practices. These findings are consistent with publications looking at gender disparities in healthcare utilization in the United States. Studies show that men, in general, are less likely to seek preventative healthcare screenings. Healthcare providers must incorporate health maintenance promotion during clinic visits. PMID:27119422

  11. Using condition-based maintenance and reliability-centered maintenance to improve maintenance in nuclear power plants

    International Nuclear Information System (INIS)

    Maintenance optimization process in nuclear power plants (NPPs) has, in recent decades, been driving the transition of maintenance strategies from time-based preventive maintenance to systematic strategies depending on both equipment condition and reliability analysis. Starting with a comparison of various types of maintenance strategies in current NPPs, this paper highlights the evident advantages of condition-based maintenance (CBM) in both technical feasibility and cost-effectiveness. This paper also expounds the theoretical foundation and application methodology of CBM, as well as the complementary relationship between CBM and RCM. Taking Daya Bay nuclear power base as a case example, we introduce in detail the experience of using Reliability-centered Maintenance (RCM) and CBM to drive maintenance improvement in NPPs, which serves as a cornerstone for the application of RCM analysis-based CBM maintenance in other plants.

    Full Text Available Factors associated with physical well being were examined in adults with end-stage renal disease (ESRD in two large hemodialysis units of the Royal Medical Services in Jordan. Utilizing the Karnofski scale we measured the functional status of 200 Patients who had been on maintenance hemodialysis for at least 12 months. A Marnofski scale of less than 70 incidents frank disability (Inability to perform routine living activities without assistance, in addition current vocational status was assessed as well as any existing comorbid conditions. The mean age of the study group was 45.2 years (range 16 to 70 and included 108 (54% males and 92 (46% females, there were 39 (19.5% diabetic patients and 27 (13.5% patients were receiving erythropoietin (EPO. The mean hematocrit of the entire group was 27.8%. As measured by Karnofski scale, 64 (32% of the patients were unable to perform routine living activity without assistance; dependence on wheelchair was reported by 9 (4.5% patients. The mean comorbidity index of patients who scored less than 70 on the Karnofski scale was 1.5 compared to 0.7 for those who scored at least 70 on the same scale (p< 0.001. Analysis of factors showed that age and diabetes mellitus affected functional status. Of the laboratory variables measured, only serum albumin concentration correlated significant with Karnofski scale. Fourteen (21.8% of the patients who scored below 70, had serum albumin concentration above 40g/L compared to 66 (48.5% of the patients who scored at least 70 on the Karnofski scale (p< 0.001. We conclude that a significant proportion of patients on maintenance hemodialysis is functionally disabled. The elderly, diabetics, patients with high co-morbidity index and those with low serum albumin are most likely to have poor functional status.

    2000-02-01

    Accelerating site cleanup to reduce facility risks to the workers, the public and the environment during a time of declining federal budgets represents a significant technical and economic challenge to U.S. Department of Energy (DOE) Operations Offices and their respective contractors. A significant portion of a facility's recurring annual expenses are associated with routine, long-term surveillance and maintenance (S&M) activities. However, ongoing S&M activities do nothing to reduce risks and basically spend money that could be reallocated towards facility deactivation. This paper discusses the background around DOE efforts to reduce surveillance and maintenance costs, one approach used to perform cost reviews, lessons learned from field implementation and what assistance is available to assist DOE sites in performing these evaluations.

  19. Maintenance of nuclear medicine instruments

    International Nuclear Information System (INIS)

    Maintenance of instruments is generally of two kinds: (a) corrective maintenance, on a non-scheduled basis, to restore equipment to a functional status by repairs; (b) preventive maintenance, to keep equipment in a specified functional condition by providing systematic inspection, quality control, detection and correction of early malfunctions. Most of the instruments used in nuclear medicine are rather complex systems built from mechanical, electrical and electronic parts. Any one of these components is liable to fail at some time or other. Repair could be done only by a specialist who is able to evaluate the condition of the various parts ranging from cables to connectors, from scintillators to photomultipliers, from microprocessors to microswitches. The knowledge of the intricacies of the various electronic components required for their repairs is quite wide and varied. The electronics industry turns out more and more multi-purpose chips which can carry out the functions of many parts used in the instruments of the earlier generation. This provides protection against unauthorized copying of the circuits but it serves another purpose as well of inhibiting repairs by non-factory personnel. These trends of the instrument design should be taken into consideration when a policy has to be developed for the repairs of the hospital based equipment

    Full Text Available In the case of a high-valuable asset, the Operation and Maintenance (O&M phase requires heavy charges and more efforts than the installation (construction phase, because it has long usage life and any accident of an asset during this period causes catastrophic damage to an industry. Recently, with the advent of emerging Information Communication Technologies (ICTs, we can get the visibility of asset status information during its usage period. It gives us new challenging issues for improving the efficiency of asset operations. One issue is to implement the Condition-Based Maintenance (CBM approach that makes a diagnosis of the asset status based on wire or wireless monitored data, predicts the assets abnormality, and executes suitable maintenance actions such as repair and replacement before serious problems happen. In this study, we have addressed several aspects of CBM approach: definition, related international standards, procedure, and techniques with the introduction of some relevant case studies that we have carried out.

  1. Demonstration of reliability centered maintenance

    International Nuclear Information System (INIS)

    Southern California Edison Company (SCE) has completed a two year demonstration of Reliability Centered Maintenance (RCM) at San Onofre Nuclear Generating Station (SONGS) Unit 2. The demonstration involved the application of detailed RCM analysis to 12 plant systems and the implementation of the preventive maintenance (PM) and testing recommendations from these analyses. Other tasks in support of the successful application and implementation included (1) the selection and prioritization of systems for RCM analysis, (2) employing RCM as the technical basis for technical specification change, and (3) development of an RCM living program. The overall objective of the project is to demonstrate that RCM can be cost-effectively performed in a nuclear plant environment. This report describes in detail the methodologies which evolved at SONGS to perform the above tasks. This report summarizes the recommendations from the analyses which include task deletions, task additions, task modifications, and design changes. A significant portion of these recommendations have been evaluated at SONGS, and the status of task implementation is described herein. Significant maintenance man-hour savings are documented on systems for which the recommendations have been evaluated and implemented. Insights of value for future RCM applications are enumerated. Finally, plans for continued use of RCM at SONGS are confirmed and described. 12 refs., 17 figs., 2 tabs

In our quest to achieve sustainable nuclear excellence, we have engaged in many debates over our degree of success in reducing the maintenance backlog at Ontario Power Generation plants. The backlog is a volume of work and a simplified analogy would be to consider it as the water level in a tank. The inflow would be the new work requests/minor work orders not completed by the Fix It Now Team, and the outflow would be the completed work orders. The equilibrium in the tank would be the result of the incoming rate of new work versus the rate of outgoing completed work. We can accommodate increasing levels for short durations, but our success depends on our ability to manage the process and achieving timely long term reduction in backlog. Although everyone seemed to have an understanding for the type of change required, it was difficult to quantify the optimum combination. Increasing the work force always seems to be an obvious choice, along with productivity improvements but there must be careful consideration given to the preventative maintenance program and resource allocation such as Support Staff, Fix It Now Team, Outages, Projects, etc. Various other factors impacting on our work rates would include training loads, sick leave and overtime. A need was identified for some analytical tool that would illustrate if our goals were attainable with our present course of action, and demonstrate what changes needed to be implemented in order to be successful. We developed a model consisting of an Excel spreadsheet that trends the backlog for each maintenance workgroup. The user populates the model with specific historical data for plant resource profiles and work execution. The program generates two sets of charts for each maintenance groups, one for actual data and another for target data. The

    Asthma is one of the most common chronic diseases in women of reproductive age, occurring in up to 8 % of pregnancies. The objective of this study is to assess the prevalence of asthma medication use during pregnancy in a large diverse cohort. We identified women aged 15-45 years who delivered a live born infant between 2001 and 2007 across 11 U.S. health plans within the Medication Exposure in Pregnancy Risk Evaluation Program (MEPREP). Using health plans' administrative and claims data, and birth certificate data, we identified deliveries for which women filled asthma medications from 90 days before pregnancy through delivery. Prevalence (%) was calculated for asthma diagnosis and medication dispensing. There were 586,276 infants from 575,632 eligible deliveries in the MEPREP cohort. Asthma prevalence among mothers was 6.7 %, increasing from 5.5 % in 2001 to 7.8 % in 2007. A total of 9.7 % (n = 55,914) of women were dispensed asthma medications during pregnancy. The overall prevalence of maintenance-only medication, rescue-only medication, and combined maintenance and rescue medication was 0.6, 6.7, and 2.4 % respectively. The prevalence of maintenance-only use doubled during the study period from 0.4 to 0.8 %, while rescue-only use decreased from 7.4 to 5.8 %. In this large population-based pregnancy cohort, the prevalence of asthma diagnoses increased over time. The dispensing of maintenance-only medication increased over time, while rescue-only medication dispensing decreased over time.

  20. Developing Reliability Based Maintenance Software for Enhancing Maintenance Performance and Aging Management

    International Nuclear Information System (INIS)

    The software of Reliability based Maintenance had been developed for maintenance and ageing maintenance purposes. The program generates information on component boundary, specification, manufacture, maintenance history, failure data, availability and degradation or ageing trend of research reactor components for use of maintenance manager for evaluating. The program was established by analyzing an existing system and designing a system that could enhance the effectiveness of the maintenance. As reference of evaluation, the program was equipped with calculation of failure rate, MTTF, MTTR, FMEA, and Root cause analysis. By using this program technician and manager could easily know status of component weather they suffer from frequent failure or degradation tendency and recommend preventive maintenance. (author)

    At any time during operation, transport flasks for radioactive material must remain as safe as they were designed to be. Beyond safety, the maintenance must assure at lowest cost that the flasks stay available and operable without any problem. An optimization is therefore necessary in order to reconcile these constraints. This paper describes the steps taken by the maintenance company MMT so that experience acquired translates into optimizing the maintenance policy, upgrading maintenance techniques, shortening down-times, decreasing personal exposure doses, and also into upgrading the design and operability of existing and future flasks. It concludes that cooperation between the maintenance company and the designer is essential for optimization. (authors)

  3. Principles of MONJU maintenance. Ageing phenomena of FBR for maintenance

    International Nuclear Information System (INIS)

    Because a fast breeder reactor (FBR) uses sodium as a coolant and there exist systems and components unique to FBR, aging phenomena to be considered in FBR are quite different from ones in a light water reactor (LWR). Therefore it is required to make a maintenance plan for FBR by considering the characteristics of FBR. In the Japanese LWRs, aging phenomena which occur in every part of all safety-related components have been extracted based on the O and M experiences and the technical evaluation on aging phenomena. In this study, aging phenomena or degradation mechanism which may occur in FBR was extracted based on the O and M experiences in the Japanese FBRs including the experiences of the overseas FBRs by using the three step method that is similar to one used in the Japanese LWRs. This paper reports the results of the special committee for considering the maintenance for Monju established in the Japan Society of Maintenology (JSM), which consists of engineers from the electric utilities having LWRs, engineers from the plant vendors, and experienced people from the academic circles.

  4. Organisational challenges of maintenance work at NPPs

    International Nuclear Information System (INIS)

    The proper working of the machinery is critical to NPP safety and productivity. Because maintenance routines and plant modifications are the activities that intervene most with the machinery, they are also the dominant sources of faults. Most of the human factor studies have relied on this fact. Due to the diversity, the temporal and spatial separation of the maintenance tasks, and the numerous competence requirements, focusing on a single task, special situation or a single psychological problem can only partially explain the requirements of maintenance work and the organisational challenges of effective maintenance. We have applied a cultural approach to maintenance work. Our aim has been to model the maintenance task and its psychological requirements and to characterise the features of organisational cultures in three NPP maintenance units. Results imply similarities and differences in the cultures and in the emphasis on the maintenance task. Maintenance activities have been under various restructuring initiatives. These changes have been experienced as stressful among the personnel. The effect of changes on the reliability of maintenance should be considered. A challenge for maintenance is to be able to build organisational structures and practices that would facilitate the fulfilment of the psychological work characteristics. (orig.)

  5. Susquehanna SES maintenance supervisor training and certification

    International Nuclear Information System (INIS)

    Susquehanna's program targets all Supervisors, Supervisor Candidates, and Temporary Supervisors that are responsible for in-plant maintenance or maintenance support activities, including: mechanical maintenance; electrical maintenance; maintenance support (labor support, radwaste, etc.); mobile construction support (mechanical and electrical); chemistry; health physics; maintenance planning; and instrument and controls. The program integrates the three major areas of direct Supervisory responsibilities: (1) Leadership and Management - Skills that require interpersonal activities that are typically humanistic and subjective; such as coaching, motivating, communications, etc. (2) Technical and Administrative - Knowledge that is directly related to the job of Supervising from the production, regulatory, accountability perspective. These topics are very objective and include training on topics such as workpackages, plant chemistry parameters, radiological concerns, etc. (3) Technical Skills - Ensure each Supervisor is technically competent in the plant systems, components, or equipment he/she is tasked with maintaining or overseeing. Typical skills found in this area are, circuit breaker maintenance, primary system sampling, or overhauling pumps

  6. The Method of Mission Oriented Maintenance

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    In a real application, equipment in good condition sometimes have to be repairedbecause the equipment does not satisfy the requirements of the mission; However, it is notnecessary to repair some equipment with failures because the failures do not affect the mission completion. In these cases, maintenance activity guided by present maintenance methodsmay sometimes affect the mission completion in time or bring about extra maintenance. To overcome the shortage of present maintenance methods, we propose an idea and method of missionoriented maintenance (MOM) to deal with the maintenance policy on these kinds of problems. This method can work out different maintenance policies corresponding to differentmissions with full consideration of missions and mission requirements for the equipment.

    Trimethylation of histone H3 lysine 9 and the subsequent binding of heterochromatin protein 1 (HP1) mediate the formation and maintenance of pericentromeric heterochromatin. Trimethylation of H3K9 is governed by the histone methyltransferase SUV39H1. Recent studies of HP1 dynamics revealed that HP1 is not a stable component of heterochromatin but is highly mobile (Cheutin, T., A.J. McNairn, T. Jenuwein, D.M. Gilbert, P.B. Singh, and T.

    Full Text Available Ontologies are continuously confronted to evolution problem. Due to the complexity of the changes to be made, a maintenance process, at least a semi-automatic one, is more and more necessary to facilitate this task and to ensure its reliability. In this paper, we propose a maintenance ontology model for a domain, whose originality is to be language independent and based on a sequence of text processing in order to extract highly related terms from corpus. Initially, we deploy the document classification technique using GRAMEXCO to generate classes of texts segments having a similar information type and identify their shared lexicon, agreed as highly related to a unique topic. This technique allows a first general and robust exploration of the corpus. Further, we apply the Latent Semantic Indexing method to extract from this shared lexicon, the most associated terms that has to be seriously considered by an expert to eventually confirm their relevance and thus updating the current ontology. Finally, we show how the complementarity between these two techniques, based on cognitive foundation, constitutes a powerful refinement process.

    In theory, the Medical Council of India (MCI) determines the standards and qualifications of medical schools. It also sanctions curricula and ensures standards. Yet no standards exist on the mode of selection in medical schools, duration of study, course content, student stipends or period of internship. It takes 4.5 years to finish medical school. Students undergo preclinical, paraclinical, and clinical training. Most courses are in English which tends to favor the urban elite. Students cannot always communicate with patients in local languages. Textbooks often provide medical examples unrelated to India. Pedagogy consists mainly of lectures and rote learning predominates. Curricula tend not to provide courses in community health. Students pick up on the elitist attitudes of the faculty. For example, faculty do not put much emphasis on community health, individual health, equity in health care delivery, and teamwork. Further the education system is not patient oriented, but hospital or disease oriented. Faculty should train students in creating sanitation programs, knowing local nutritious foods, and in making community diagnoses. Yet they tend to be practitioners 1st then educators. Further faculty are not paid well and are not always invited to take part in improving curriculum, so morale is often low. Moreover experience in health planning and management issues is not required for administrators. In addition, medical schools are not well equipped with learning aids, libraries, or teaching staff. Tax revenues finance medical education. 75% of graduating physicians set up a private practice. Further many physicians go to urban areas. 34-57% emigrate to other countries. The problems of medical education will not be solved until the political and economic system becomes more responsive to the health needs of the people.

  19. Maintenance technologies on nuclear power plants

    International Nuclear Information System (INIS)

    As nuclear power plants in Japan are proud of their operation results with high reliability at a viewpoint of the world, one of main factors supporting on this high reliability is 'maintenance'. On the other hand, U.S.A. has not carried out thorough preventive maintenance like Japan but systematically progressed adequacy of maintenance at a center of condition based maintenance (CBM) under its success. In Japan, reduction of periodical inspection time and introduction of the CBM are begun to wrestle with adequacy of maintenance. Here was introduced on efforts on maintenance, inspection and technical development carried out at the nuclear power plants, and also on actions on 'maintenance' in Japan. Here were described on present state of maintenance and inspection in the nuclear power stations, efforts to reduce periodical inspection time, efforts on countermeasure for high aging, conditions on technical development of maintenance and inspection, working results on renewal engineering of large scale apparatuses, and efforts on upgrading of technology on maintenance and inspection.

  5. Medical migration.

    Loefler, I J

    2001-10-01

    The issue of professional migration, however emotional it may have become, ought not to be regarded in moralizing terms. The history of western medicine is the history of migrating physicians. A doctor who moves from a locality to another to take up a new assignment there cannot be said to have "abandoned his patients". This emotional bond has become the victim of specialization and of depersonalization of medical services and not of medical migration, brain drain or otherwise. The primary reason for medical migration is not financial; the desire to migrate usually begins with the desire to learn. Professionals crave in the first line for professional satisfaction. The migration of medical manpower cannot be stopped with administrative measures and will not be stopped by exhortations and appeals, moralization and condemnations. Brain drain is a global phenomenon and has always been so. A country which loses its professionals, its doctors, should examine the social relationships within the profession and should investigate whether the opportunities for deriving professional satisfaction from everyday work exist or whether these have been thwarted by the hierarchy, conservatism, cronyism and the general lack of comprehension of what good medical care is about.

    2015-06-01

    The Medical Renaissance started as the regular Renaissance did in the early 1400s and ended in the late 1600s. During this time great medical personalities and scholar humanists made unique advances to medicine and surgery. Linacre, Erasmus, Leonicello and Sylvius will be considered first, because they fit the early classic Renaissance period. Andreas Vesalius and Ambroise Paré followed thereafter, making outstanding anatomical contributions with the publication of the "Human Factory" (1543) by Vesalius, and describing unique surgical developments with the publication of the "The Apologie and Treatise of Ambroise Paré." At the end of the Renaissance and beginning of the New Science, William Harvey, noted British medical doctor and cardiovascular researcher, discovered the general circulation. He published his findings in "The Motu Cordis" in 1628 (Figure 1). The Medical Renaissance, in summary, included a great number of accomplished physicians and surgeons who made especial contributions to human anatomy; Vesalius assembled detailed anatomical information; Paré advanced surgical techniques; and Harvey, a medical genius, detailed the circulatory anatomy and physiology.

Step-by-step details are provided for the definition of organizational needs -- who should be tested, on which tasks; decisions about test format -- what the test should look like; and calculations of costs and benefits. The primary focus is on the construction of proficiency tests, in particular, written tests of job knowledge and performance tests of job skills. Examples from test-construction activities at two nuclear power plants illustrate the general principles and practical details. Refinement and validation of the tests are discussed thoroughly, and issues and problems that arise in developing and administering a testing program are reviewed. 17 refs., 30 figs., 30 tabs

  8. Comparing Maintenance Strategies for Overlays

    Krishnamurthy, Supriya; Aurell, Erik; Haridi, Seif

    2007-01-01

    In this paper, we present an analytical tool for understanding the performance of structured overlay networks under churn based on the master-equation approach of physics. We motivate and derive an equation for the average number of hops taken by lookups during churn, for the Chord network. We analyse this equation in detail to understand the behaviour with and without churn. We then use this understanding to predict how lookups will scale for varying peer population as well as varying the sizes of the routing tables. We then consider a change in the maintenance algorithm of the overlay, from periodic stabilisation to a reactive one which corrects fingers only when a change is detected. We generalise our earlier analysis to underdstand how the reactive strategy compares with the periodic one.

    2007-01-17

    "Natura non facit saltum" (nature makes no leap) the Latins used to say, meaning that nature does not like discontinuities. Cells make no exception and indeed any discontinuity in the DNA double helix is promptly detected, triggering an alteration of cell proliferation and an attempt to repair. Yet, linear chromosomes bear DNA ends that are compatible with normal cell proliferation and they escape, under normal conditions, any repair. How telomeres, the chromosomes tips, achieve that is not fully understood. We recently observed that the Rad9/Hus1/Rad1 (911) complex, previously known for its functions in DNA metabolism and DNA damage responses, is constitutively associated with telomeres and plays an important role in their maintenance. Here, we summarize the available data and discuss the potential mechanisms of 911 action at telomeres.

  12. Inspection of licensee - Maintenance programme and activities

    International Nuclear Information System (INIS)

    An effective maintenance programme is critical to sustained safe and reliable operation of nuclear power plants. The Working Group on Inspection Practices (WGIP) concluded that when a licensee has an effective maintenance programme, the overall operating safety of the plant is improved and the protection of public health and safety enhanced. All Regulatory Bodies (RB) consider maintenance to be an important area for oversight. Although a variety of inspection practices are being used; RB are actively monitoring licensee performance. Specifically the following conclusions were reached and commendable practices identified: - Maintenance oversight by regulators appears to be in a stable continuous improvement state. Most regulators are executing inspection oversight based on an existing regulatory framework. - The performance of a licensee's maintenance programme is recognized as important part of maintaining nuclear safety. The result of the maintenance program assessment is included in the overall performance assessment of a license. - Maintenance inspection activities are recognized as an important part of the regulatory oversight process. Inspection activities are based on the safety significance and nature of work being performed by the licensee. - The effectiveness of the maintenance inspection activities is recognized to rely on properly qualified inspectors; who are adequately supported by specialists. Training and qualification of inspectors should be based on how the RB reviews and inspects licensee maintenance programmes. - Reporting requirements are identified to provide information on the licensees maintenance programme, and to help guide inspection activities. - Performance Indicators are recognized as a useful tool for helping focus regulatory activities. Basic PI are identified and tracked by the RB, and use of PI by the licensee is monitored. - Inspections are designed to confirm that the licensee is planning and scheduling maintenance with due

  4. Conceptualization of an intellectual maintenance management system

    International Nuclear Information System (INIS)

    It is studied in many research institute to enhance availability and safety of nuclear power plants operation and maintenance. On this account, development of autonomous plants has been carried out to replace the role of operators with artificial intelligence and autonomous robots. We have been developing an intellectual maintenance management system since 1994. As the first step, concept of an intellectual maintenance management system was constructed. The intellectual maintenance managerial system is in charge of maintenance function of an autonomous plant. The intellectual maintenance managerial system has three functions which is monitoring state and judging abnormal machine and deciding maintenance plan by autonomy. This system has an important role of indication and communication of the result to an autonomous operation system and autonomous robot. In this examination, we adopted the distributed and cooperative system technique by multi-agent of AI technology and examined a method to enforce problem solving by cooperation of sensor and actuator. In this report, we examined trouble detection and troubleshooting evaluation and maintenance plan decision function by the distributed and cooperative system technology, the distributed and cooperative system communication-function that these information releases functions was taken on. In conceptualization of the intellectual maintenance managerial system, we clarified of major functions to constitute this system and relation between autonomous operation system and autonomous robots. We clarified the information exchange scheme between this system and an outside system furthermore. In future, we will prototype each function and inspect the total system. (author)

  7. A proactive condition-based maintenance strategy with both perfect and imperfect maintenance actions

    International Nuclear Information System (INIS)

    This paper deals with a proactive condition-based maintenance (CBM) considering both perfect and imperfect maintenance actions for a deteriorating system. Perfect maintenance actions restore completely the system to the ‘as good as new’ state. Their related cost are however often high. The first objective of the paper is to investigate the impacts of imperfect maintenance actions. In fact, both positive and negative impacts are considered. Positive impact means that the imperfect maintenance cost is usually low. Negative impact implies that (i) the imperfect maintenance restores a system to a state between good-as-new and bad-as-old and (ii) each imperfect preventive action may accelerate the speed of the system's deterioration process. The second objective of the paper is to propose an adaptive maintenance policy which can help to select optimally maintenance actions (perfect or imperfect actions), if needed, at each inspection time. Moreover, the time interval between two successive inspection points is determined according to a remaining useful life (RUL) based-inspection policy. To illustrate the use of the proposed maintenance policy, a numerical example finally is introduced. - Highlights: • A new imperfect maintenance model for deterioration system is proposed. • Both positive and negative impacts of an imperfect maintenance action are investigated. • An adaptive condition-based maintenance policy is introduced. • The optimal number of useful imperfect maintenance actions for each life cycle is optimally provided

  10. Mine maintenance - the cost of operation

    Energy Technology Data Exchange (ETDEWEB)

    Kreilis, O.; Singleton, T. [Southern Engineering Services (Australia)

    1998-12-31

    Increasing world competition puts pressure on sales volumes and prices. This in turn reduces potential profit margins. This in turn increases the focus on costs. Increasing demands on quality and service puts pressure on delivery performance - the right product at the right time. This in turn reduces the scope for errors and delays - and this in turn increases focus on equipment reliability. In the mining industry, both costs and equipment reliability have one significant thing in common - they are driven substantially by maintenance. Maintenance, once the Cinderella of the boardroom is a pivotal function and demands management attention and, if managed well, can be a source of competitive advantage. They made the decision to put maintenance high on their agendas because they realised that good maintenance is a vital factor in achieving excellence. Maintenance, because of its impact on return on capital, is a key driver of performance. By reducing maintenance costs, companies can improve their performance. Top managers are increasingly recognising that maintenance is an area in which they must be involved. As Australian mining and metallurgical companies look to the year 2000 and beyond, maintenance will become an increasingly strategic function, capable of delivering sustainable competitive advantage to those companies that get it right. 7 refs., 5 figs.

  11. Preparing and organizing inspection and maintenance

    International Nuclear Information System (INIS)

    The philosophy and goals of maintenance are discussed. The main principles in organizing the maintenance of the Loviisa power plant are: the people responsible for maintenance during operation are also responsible for maintenance during outages; outside contractors are used for the peak loads during outages but the planning and monitoring of outages is the responsibility of the plant personnel. Technically skilled and highly motivated personnel is the most important prerequisite of success. Loviisa has for several years very successfully utilized two different types of salary bonus system. The reloading outage bonus system gives more money per hour during the outage and an additional increase for all plant people participating in the outage work, if the duration of the outage is shorter than planned. The amount of the extra bonus depends on the final duration of the outage. The operation and maintenance of the Loviisa plant is based on quality assurance, operation and maintenance procedures. The annual and long-term plan of actions are controlled by regular planning meetings which utilize all reports produced by the maintenance groups. The technical outage report contains all technical information gathered during the outages according to the preventive maintenance and in-service inspection programs. The condition monitoring programs of the plant components were developed by the Research Laboratories of Imatran Voima and financed by the plant. (Z.S.) 9 figs., 5 refs

    2016-05-01

    There is growing recognition within the medical education community that medical education in this country needs to be changed to better prepare doctors for the challenges they will face in providing their patients high-quality medical care. A competency-based medical education (CBME) approach was endorsed by the Accreditation Council for Graduate Medical Education and the American Board of Medical Specialties approximately 15 years ago, and a self-designated group-the International Competency-Based Medical Education (ICBME) Collaborators-is now calling on members of the medical education community to join them in their effort to establish CBME as the approach to be used in transforming medical education, not only in the United States but also around the world.In response to an article in this issue by a group of ICBME Collaborators, the author argues that more evidence about the effectiveness of CBME is needed before a global shift to this approach is undertaken. It is time for major organizations and foundations that are committed to improving medical education to step forward and take the lead in partnering with the medical education community to conduct a critical evaluation of CBME. In addition, maintenance of certification, relicensure, and continuing medical education programs should be evaluated for their effectiveness in ensuring that physicians are clinically competent not only at the beginning of their career but also until the end.

  17. Maintenance Approaches for Different Production Methods

    Directory of Open Access Journals (Sweden)

    Mungani, Dzivhuluwani Simon

    2013-11-01

    Full Text Available Various production methods are used in industry to manufacture or produce a variety of products needed by industry and consumers. The nature of a product determines which production method is most suitable or cost-effective. A continuous process is typically used to produce large volumes of liquids or gases. Batch processing is often used for small volumes, such as pharmaceutical products. This paper discusses a research project to determine the relationship between maintenance approaches and production methods. A survey was done to determine to what extent three maintenance approaches reliability-centred maintenance (RCM, total productive maintenance (TPM, and business-centred maintenance (BCM are used for three different processing methods (continuous process, batch process, and a production line method.

Maintenance offers numerous opportunities to reduce the influence of foundry processes on the natural environment and utilize resources more efficiently. Maintenance activities can help to reduce losses and thereby improve the efficiency of the processes used in the production of resources (e.g. raw materials, energy, etc., especially in areas such as: the choice of an appropriate strategy for the maintenance of machinery and equipment (e.g. reactive, preventive, proactive; inventory management of spare parts; lubrication management and management of technology media.

  19. Effective maintenance practices to manage system aging

    Science.gov (United States)

    Chockie, Alan; Bjorkelo, Kenneth

    A study for the Nuclear Regulatory Commission was recently undertaken to identify effective maintenance practices that could be adapted by the nuclear industry in the United States to assist in managing the aging degradation of plant systems and components. Four organizations were examined to assess the influence of maintenance programs on addressing the system and component aging degradation issues. An effective maintenance program was found to be essential to the management of system and component aging. Four key elements of an effective maintenance program that are important to an aging management were identified: (1) the selection of critical systems and components; (2) the development of an understanding of aging through the collection and analysis of equipment performance information; (3) the development of appropriate preventive and predictive maintenance tasks to manage equipment and system aging degradation; and (4) the use of feedback mechanisms to continuously improve the management of aging systems and components. These elements were found to be common to all four organizations.

  20. Preventive maintenance for mechanical components

    International Nuclear Information System (INIS)

    In nuclear power stations as in other industrial plants, there are active and passive components whose failure is permissible only in exceptional cases both from a safety and/or economic view. Failure in this context means loss of integrity of a supporting wall, insufficient function and/or unstoppable leakage. A systematic defect must be excluded as cause of failure; the consequences of failure must be manageable. During operation, measures must be taken to maintain the required quality and detect consequences of damage mechanisms at an early stage, prior to failure. This is achieved by preventive maintenance in accordance with the latest state of knowledge. To exclude systematic errors, the quality standard of components must be re-checked every once in a while as the effects of damage mechanisms and the state of knowledge are time-dependent parameters. This requires an integrated concept, e.g. for life and ageing management, in whose context a comprehensive knowledge base is developed and regularly updated. (orig.)

  1. Innovative techniques in maintenance training

    International Nuclear Information System (INIS)

    Performance based training has its beginning with a Job and Task Analysis (JTA), and culminates with the presentation of the developed training material. For optimum training effectiveness, a post training feedback mechanism is utilized to update and/or upgrade material content. A Job Task Analysis uses subject matter experts and supporting documentation to define the skills and knowledge necessary to perform functions from total position responsibilities to the simplest tasks, depending on desired results. Once skills and knowledge are defined, decisions on needed curriculum can be made including objectives, exams, and training settings (classroom, lab, or job site). This focused curriculum and the determination of best training settings are innovations of the performanced based training system. Past training experience has illustrated that a baseline level of classroom training acts as a catalyst for optimum hands-on training. The trainee exits the training phase able to do the job proficiently. This provides the training customer with quality training with minimum investment. Maintenance Training at Comanche Peak Steam Electric Station (CPSES) integrates the knowledge and skill needs by providing the individual with focused classroom presentations followed by sufficient laboratory time to practice actual task activities. Labs are configured to represent plant equipment and work environment to the maximum extent possible and duplicate in-plant work orders and procedures are used. This allows actions to be analyzed and corrective feedback given as necessary. As an added benefit, any mistakes made during training has minimal, if any, impact on plant performance

  2. Preventative maintenance of straddle carriers

    2015-02-01

    Full Text Available Background: Robotic vehicles such as straddle carriers represent a popular form of cargo handling amongst container terminal operators.Objectives: The purpose of this industry-driven study is to model preventative maintenance (PM influences on the operational effectiveness of straddle carriers.Method: The study employs historical data consisting of 21 273 work orders covering a 27-month period. Two models are developed, both of which forecast influences of PM regimes for different types of carrier.Results: The findings of the study suggest that the reliability of the straddle fleet decreases with increased intervals of PM services. The study also finds that three factors – namely resources, number of new straddles, and the number of new lifting work centres – influence the performances of straddles.Conclusion: The authors argue that this collaborative research exercise makes a significant contribution to existing supply chain management literature, particularly in the area of operations efficiency. The study also serves as an avenue to enhance relevant management practice.

    International Nuclear Information System (INIS)

    In this study, a structure of code and standard system for plant maintenance is discussed along a process of maintenance activities. As a result of consideration, it was concluded as follows. (1) It is assumed that the entire system of maintenance codes and standards consists of four standards, that is, standards regarding maintenance planning, maintenance implementation, evaluation of inspection/maintenance results and corrective measures. (2) The maintenance guidelines and fitness-for-service codes discussed already so far occupies a position in the entire system of maintenance codes and standards. (3) Maintenance codes and standards, which have higher priority, should be developed. (author)

    2015-10-01

    In re-listening to the lectures of Charles Townes shortly after the invention of the laser (e.g., in the Boston Science Museum), one can already have a realistic vision of the potentialities of this new tool in the field of medical therapy, as evidenced by the use of the laser in ophthalmology to cure retinal detachment in the 1960's. Since then, applications have flourished in the domain of therapy. We will thus illustrate here only some of the main fields of application of medical lasers. On the opposite, the use of lasers in medical imaging is, with one exception in ophthalmology, still at the development level. It is becoming a diagnostic tool in addition to high performance imaging facilities that are often very expensive (such as CT scan, Magnetic Resonance Imaging (MRI) and nuclear imaging). Even if progress is sometimes slow, one can now image with light inside the human body, in spite of the strong scattering of light by tissues, in the same way as a pathologist sees surgical specimens.

    The medical investigations completed on the KC-135 during FY 1991 in support of the development of the Health Maintenance Facility and Medical Operations are presented. The experiments consisted of medical and engineering evaluations of medical hardware and procedures and were conducted by medical and engineering personnel. The hardware evaluated included prototypes of a crew medical restraint system and advanced life support pack, a shuttle orbiter medical system, an airway medical accessory kit, a supplementary extended duration orbiter medical kit, and a surgical overhead canopy. The evaluations will be used to design flight hardware and identify hardware-specific training requirements. The following procedures were evaluated: transport of an ill or injured crewmember at man-tended capability, surgical technique in microgravity, transfer of liquids in microgravity, advanced cardiac life support using man-tended capability Health Maintenance Facility hardware, medical transport using a model of the assured crew return vehicle, and evaluation of delivery mechanisms for aerosolized medications in microgravity. The results of these evaluation flights allow for a better understanding of the types of procedures that can be performed in a microgravity environment.

  11. Reduction of Maintenance Error Through Focused Interventions

    Science.gov (United States)

    Kanki, Barbara G.; Walter, Diane; Rosekind, Mark R. (Technical Monitor)

    1997-01-01

    It is well known that a significant proportion of aviation accidents and incidents are tied to human error. In flight operations, research of operational errors has shown that so-called "pilot error" often involves a variety of human factors issues and not a simple lack of individual technical skills. In aircraft maintenance operations, there is similar concern that maintenance errors which may lead to incidents and accidents are related to a large variety of human factors issues. Although maintenance error data and research are limited, industry initiatives involving human factors training in maintenance have become increasingly accepted as one type of maintenance error intervention. Conscientious efforts have been made in re-inventing the "team" concept for maintenance operations and in tailoring programs to fit the needs of technical operations. Nevertheless, there remains a dual challenge: to develop human factors interventions which are directly supported by reliable human error data, and to integrate human factors concepts into the procedures and practices of everyday technical tasks. In this paper, we describe several varieties of human factors interventions and focus on two specific alternatives which target problems related to procedures and practices; namely, 1) structured on-the-job training and 2) procedure re-design. We hope to demonstrate that the key to leveraging the impact of these solutions comes from focused interventions; that is, interventions which are derived from a clear understanding of specific maintenance errors, their operational context and human factors components.

  12. Improving regulatory oversight of maintenance programs

    International Nuclear Information System (INIS)

    Safe nuclear power plant operation requires that risks due to failure or unavailability of Structures, Systems and Components (SSCs) be minimized. Implementation of an effective maintenance program is a key means for achieving this goal. In its regulatory framework, the important relationship between maintenance and safety is acknowledged by the CNSC. A high level maintenance program requirement is included in the Class I Facilities Regulations. In addition, the operating licence contains a condition based on the principle that the design function and performance of SSCs needs to remain consistent with the plant's design and analysis documents. Nuclear power plant licensees have the primary responsibility for safe operation of their facilities and consequently for implementation of a successful maintenance program. The oversight role of the Canadian Nuclear Safety Commission (CNSC) is to ensure that the licensee carries out that responsibility. The challenge for the CNSC is how to do this consistently and efficiently. Three opportunities for improvement to regulatory maintenance oversight are being pursued. These are related to the regulatory framework, compliance verification inspection activities and monitoring of self-reporting. The regulatory framework has been improved by clarifying expectations through the issuance of S-210 'Maintenance Programs for Nuclear Power Plants'. Inspection activities have been improved by introducing new maintenance inspections into the baseline program. Monitoring is being improved by making better use of self-reported and industry produced maintenance related performance indicators. As with any type of program change, the challenge is to ensure the consistent and optimal application of regulatory activities and resources. This paper is a summary of the CNSC's approach to improving its maintenance oversight strategy. (author)

    International Nuclear Information System (INIS)

    This Fiscal Year (FY) 1994 Site Maintenance Action Plan (SMAP) is Part II of the Site Maintenance Plan, and has been written by Westinghouse Hanford Company (WHC) to outline the requirements stated in DOE Order 4330.4B, Maintenance Management Program, Chapter 1, Paragraph 3.3.1. The SMAP provides an annual status of maintenance initiatives completed and planned, a summary of performance indicators, a summary of maintenance backlog, a listing of real property and capital equipment maintenance cost estimates that were used to create the FY 1996 infrastructure and maintenance budget input, and a listing of proposed line item and general plant projects. Additionally, assumptions for various Site programs are listed to bring the Site Maintenance Plan into focus with overall Site activities. The primary mission at Hanford is to clean up the Site. In this cleanup process WHC will provide scientific and technological expertise to meet global needs, and partnership with stakeholders in the region to develop regional economic diversification. Other missions at the Hanford Site include energy research and development, and waste management and disposal activities. Their primary mission has a 30-year projected life span and will direct the shutting down and cleanup of defense production facilities and the Fast Flux Test Facility. This long-term mission requires continuous maintenance and in many instances, replacement of existing basic infrastructure, support facilities, and utilities. Without adequate maintenance and capital funding these infrastructure, support facilities, and utilities will continue to deteriorate causing an increase in backlogged work

  2. Plant Maintenance. The Licensee's Viewpoint

    International Nuclear Information System (INIS)

    Plant maintenance is a very complex process which requires considerable effort from both within the maintenance process and also many support activities. It is important that the plant maintenance policy is translated into a maintenance programme which will define all relevant aspects of the maintenance. An aspect of this maintenance programme will be a maintenance catalogue which will define the maintenance activities to be carried out and at what frequencies. This paper is aimed at discussing the maintenance philosophy and resulting maintenance catalogues currently adopted in Nuclear Electric Ltd, and in particular at Heysham 2 Power Station. It goes on to consider whether these maintenance catalogues contain the optimum maintenance and if not should they be changed. If change is required, the process by which this change will be brought about is also discussed. (author)

  8. Maintenance grouping for multi-component systems with availability constraints and limited maintenance teams

    International Nuclear Information System (INIS)

    The paper deals with a maintenance grouping approach for multi-component systems whose components are connected in series. The considered systems are required to serve a sequence of missions with limited breaks/stoppage durations while maintenance teams (repairmen) are limited and may vary over time. The optimization of the maintenance grouping decision for such multi-component systems leads to a NP-complete problem. The aim of the paper is to propose and to optimize a dynamic maintenance decision rule on a rolling horizon. The heuristic optimization scheme for the maintenance decision is developed by implementing two optimization algorithms (genetic algorithm and MULTIFIT) to find an optimal maintenance planning under both availability and limited repairmen constraints. Thanks to the proposed maintenance approach, impacts of availability constraints or/and limited maintenance teams on the maintenance planning and grouping are highlighted. In addition, the proposed grouping approach allows also updating online the maintenance planning in dynamic contexts such as the change of required availability level and/or the change of repairmen over time. A numerical example of a 20-component system is introduced to illustrate the use and the advantages of the proposed approach in the maintenance optimization framework. - Highlights: • A dynamic maintenance grouping strategy is proposed for multi-component systems. • A grouping approach based on rolling horizon, GA and MULIFIT algorithms is proposed. • Impacts of availability and/or limited repairmen constraints are highlighted. • An optimal planning under availability and/or limited repairmen constraints is given. • The maintenance planning can be dynamically updated in the presence of dynamic contexts

    A main problem in maintenance in general, and in power plants and related equipment in particular, is the lack of a practical, consistent, and adaptive performance measure that provides a focused feedback and integrates preventive and corrective modes of maintenance. The presentation defines concepts of world class and benchmarking. Desirable features in an appropriate performance measure are identified. It then, demonstrates current practices in maintenance and criticises their shortcomings. An alternative model is presented through a case study. The model monitors performance from a general view, and then offers a focused analysis. The main conclusion is that the proposed model offers an adaptive and a dynamic framework, and hence production and maintenance are integrated in a `real time` environment. The system is also flexible in working with any other criteria whether they are of a quantitative or a qualitative nature. (orig.) 16 refs.

    Full Text Available Railroad maintenance engineering plays an important role on availability of roads and reducing the cost of railroad incidents. Rail is of the most important parts of railroad industry, which needs regular maintenance since it covers a significant part of total maintenance cost. Any attempt on optimizing total cost of maintenance could substantially reduce the cost of railroad system and it can reduce total cost of the industry. The paper presents a new method to estimate the cost of rail failure using different cost components such as cost of inspection and cost of risk associated with possible accidents. The proposed model of this paper is used for a real-world case study of railroad transportation of Tehran region and the results have been analyzed.

    1988-01-01

    Expert Missile Maintenance Aid (EMMA) is a first attempt to enhance maintenance of the tactical munition at the field and depot level by using artificial intelligence (AI) techniques. The ultimate goal of EMMA is to help a novice maintenance technician isolate and diagnose electronic, electromechanical, and mechanical equipment faults to the board/chassis level more quickly and consistently than the best human expert using the best currently available automatic test equipment (ATE). To this end, EMMA augments existing ATE with an expert system that captures the knowledge of design and maintenance experts. The EMMA program is described, including the evaluation of field-level expert system prototypes, the description of several study tasks performed during EMMA, and future plans for a follow-on program. This paper will briefly address several study tasks performed during EMMA. The paper concludes with a discussion of future plans for a follow-on program and other areas of concern.

  3. Maintenance evaluation for space station liquid systems

    Science.gov (United States)

    Flugel, Charles

    1987-01-01

    Many of the thermal and environmental control life support subsystems as well as other subsystems of the space station utilize various liquids and contain components which are either expendables or are life-limited in some way. Since the space station has a 20-year minimum orbital lifetime requirement, there will also be random failures occurring within the various liquid-containing subsystems. These factors as well as the planned space station build-up sequence require that maintenance concepts be developed prior to the design phase. This applies to the equipment which needs maintenance as well as the equipment which may be required at a maintenance work station within the space station. This paper presents several maintenance concepts for liquid-containing items and a flight experiment program which would allow for evaluation and improvement of these concepts so they can be incorporated in the space station designs at the outset of its design phase.

  7. A practical application of reliability centered maintenance

    International Nuclear Information System (INIS)

    This paper describes a practical and cost effective method for applying Reliability Centered Maintenance (RCM) principles to improve the effectiveness of an existing Preventive Maintenance program. While this program was developed for a modern nuclear power plant, it is based on the premise that many plants already have effective Maintenance and PM Programs, some of which may be relatively comprehensive, even at non-nuclear facilities. Therefore, the objective of this type of upgrade project is to identify and select the most effective PM tasks, whether currently active, or recommended new tasks or revisions, and to eliminate ineffective tasks. Then, apply those changes within the existing programs in a way that will allow the most efficient allocation of resources. It is anticipated that this program will enhance plant safety, improve plant availability and the reliability of plant equipment, as well as prevent escalation of maintenance costs when fully implemented

  8. Airline experience with reliability-centered maintenance

    International Nuclear Information System (INIS)

    Reliability-Centered Maintenance is a process for developing preventive maintenance programs. Its concepts evolved from the post WWII experience of the airline community. Its genesis was in a paper by F. Stanley Nowlan and Thomas D. Matteson of United Airlines for the American Institute of Aeronautics and Astronautics in 1967. Its first application was to the Boeing 747. It has subsequently been adopted by the FAA and the Department of Defense and applied to many new transport and military aircraft. Its objective is applicable and effective preventive maintenance and it has proven to be a highly effective replacement for the prior intuitive processes for selective preventive maintenance tasks. It focuses on system functions, functional failures, then dominant failure modes and effects. It then uses a decision tree to classify failure criticality and identify applicable and effective tasks. The result is a program focused on maintaining inherent safety and reliability at minimum cost. (orig.)

  9. Operations and maintenance plans for the TFTR

    International Nuclear Information System (INIS)

    Princeton University Plasma Physics Laboratory (PPPL) is constructing a Tokamak Fusion Test Reactor (TFTR) scheduled to begin operation for fusion research experiments in late 1981, first with hydrogen and deuterium plasmas and later, in the second phase, using tritium for high power fusion studies. This latter mode will introduce considerable complexity to operation and maintenance of the TFTR in terms of meeting requirements for tritium handling, adequate radiation shielding, and corrective and preventive maintenance procedures. In this paper we discuss plans for the installation and preoperational testing of the major subsystems of TFTR, proposed start-up and operating scenarios for the device and the system of operational control. In addition, the TFTR Maintenance Plan and related procedures for specific major maintenance tasks are described, including the use of remote handling equipment and remote manipulators. Each of these topics is addressed in terms of the current status of planning and development

  10. Probabilistic analysis of free ways for maintenance

    International Nuclear Information System (INIS)

    The safety during the maintenance interventions is treated in limited manner and in general independent of the systems of management of the maintenance. This variable is affected by multiple technical or human factors many times subjective and difficult to quantifying, what limits the design of preventive plans. However, some factors constitute common points: the isolation configurations during the free ways (bank drafts in the oil industry) and the human errors associated to their violation. This characteristic allowed to develop the analysis of such situations through the methodology of fault trees that it links faults of teams and human errors cohesively. The methodology has been automated inside the MOSEG Win Ver 1.0 code and the same one can embrace from the analysis of a particular situation of free way until that of a complete strategy of maintenance from the point of view of the safety of the maintenance personal.

    Information and communication technology (ICT) and mechatronics play a basic role in medical robotics and computer-aided therapy. In the last three decades, in fact, ICT technology has strongly entered the health-care field, bringing in new techniques to support therapy and rehabilitation. In this frame, medical robotics is an expansion of the service and professional robotics as well as other technologies, as surgical navigation has been introduced especially in minimally invasive surgery. Localization systems also provide treatments in radiotherapy and radiosurgery with high precision. Virtual or augmented reality plays a role for both surgical training and planning and for safe rehabilitation in the first stage of the recovery from neurological diseases. Also, in the chronic phase of motor diseases, robotics helps with special assistive devices and prostheses. Although, in the past, the actual need and advantage of navigation, localization, and robotics in surgery and therapy has been in doubt, today, the availability of better hardware (e.g., microrobots) and more sophisticated algorithms(e.g., machine learning and other cognitive approaches)has largely increased the field of applications of these technologies,making it more likely that, in the near future, their presence will be dramatically increased, taking advantage of the generational change of the end users and the increasing request of quality in health-care delivery and management.

  13. Contribution to DEMO reactor RH maintenance assessment

    International Nuclear Information System (INIS)

    The scope of this paper is a preliminary assessment of the maintenance scheme in support of the European study for the next generation of fusion reactor: DEMO. Despite other fusion machine requiring remote handling maintenance operations, DEMO is supposed to work under steady state operational conditions. Therefore, requirement on the maintenance scheme is stronger. To target a good availability of the machine along machine operation plan, it is necessary to draw an adequate maintenance scheme. Indeed, due to the high fluxes generated by the plasma in the vacuum vessel, the first wall lifetime is limited, so the frequent replacement is necessary. On current fusion experimental machine, as first wall load conditions are less severe, DEMO condition implies high level of requirement on maintenance time. During DEMO lifetime, several full first wall replacements are expected. To provide access to the vacuum vessel machine for first wall removal, preparatory work is required to set the machine to adequate maintenance conditions and to open the machine properly, the same situation at the end of the maintenance period. Shutdown duration for first wall replacement should be as short as possible to reach the availability target of the machine. From this statement, the maintenance duration should not exceed 20% of the total lifetime of the reactor operation. First wall segmentation (i.e. total number of component to replace) has a high impact onto the replacement time. Considering the number of feasible designs for the first wall segmentation, we concentrate remote handling concept assessments one type of segmentation, the one minimizing the numbers of modules to replace . Assumption on Divertor segmentation for these DEMO studies have similarities with Divertor ITER design; therefore ITER design output is relevant . We assume divertor removal performed in shadow time, while removing the other first wall modules.

  16. Mining truck scheduling with stochastic maintenance cost

    Institute of Scientific and Technical Information of China (English)

    Erkan TOPAL; Salih RAMAZAN

    2012-01-01

    Open pit mining operations utilize large scale and expensive equipment.For the mines implementing shovel and truck operation system,trucks constitute a large portion of these equipment and are used for hauling the mined materials.In order to have sustainable and viable operation,these equipment need to be utilized efficiently with minimum operating cost.Maintenance cost is a significant proportion of the overall operating costs.The maintenance cost of a truck changes non-linearly depending on the type,age and truck types.A new approach based on stochastic integer programming (SIP) techniques is used for annually scheduling a fixed fleet of mining trucks in a given operation,over the life of mine (multi-year time horizon) to minimize maintenance cost.The maintenance cost data in mining usually has uncertainty caused from the variability of the operational conditions at mines.To estimate the cost,usually historic data from different operations for new mines,and/or the historic data at the operating mines are used.However,maintenance cost varies depending on road conditions,age of equipment and many other local conditions at an operation.Traditional models aim to estimate the maintenance cost as a deterministic single value and financial evaluations are based on the estimated value.However,it does not provide a confidence on the estimate.The proposed model in this study assumes the truck maintenance cost is a stochastic parameter due to the significant level of uncertainty in the data and schedules the available fleet to meet the annual production targets.The scheduling has been performed by applying both the proposed stochastic and deterministic approaches.The approach provides a distribution for the maintenance cost of the optimized equipment schedule minimizing the cost.

    Cooperation is widespread in human societies, but its maintenance at the group level remains puzzling if individuals benefit from not cooperating. Explanations of the maintenance of cooperation generally assume that cooperative and non-cooperative behavior in others can be assessed and copied accurately. However, humans have a well known capacity to deceive and thus to manipulate how others assess their behavior. Here, we show that hypocrisy - claiming to be acting cooperatively while acting ...

    The scope of this paper is a preliminary assessment of the maintenance scheme in support of the European study for the next generation of fusion reactor: DEMO. Despite other fusion machine requiring remote handling maintenance operations, DEMO is supposed to work under steady state operational conditions. Therefore, requirement on the maintenance scheme is stronger. To target a good availability of the machine along machine operation plan, it is necessary to draw an adequate maintenance scheme. Indeed, due to the high fluxes generated by the plasma in the vacuum vessel, the first wall lifetime is limited, so the frequent replacement is necessary. On current fusion experimental machine, as first wall load conditions are less severe, DEMO condition implies high level of requirement on maintenance time. During DEMO lifetime, several full first wall replacements are expected. To provide access to the vacuum vessel machine for first wall removal, preparatory work is required to set the machine to adequate maintenance conditions and to open the machine properly, the same situation at the end of the maintenance period. Shutdown duration for first wall replacement should be as short as possible to reach the availability target of the machine. From this statement, the maintenance duration should not exceed 20% of the total lifetime of the reactor operation. First wall segmentation (i.e. total number of component to replace) has a high impact onto the replacement time. Considering the number of feasible designs for the first wall segmentation, we concentrate remote handling concept assessments one type of segmentation, the one minimizing the numbers of modules to replace . Assumption on Divertor segmentation for these DEMO studies have similarities with Divertor ITER design; therefore ITER design output is relevant . We assume divertor removal performed in shadow time, while removing the other first wall modules.

  12. Reliability centred maintenance - an overview in Indian PHWR context

    International Nuclear Information System (INIS)

    Over the last few decades, attitude and approach to maintenance has changed very rapidly together with new maintenance techniques, growing awareness of effect of equipment failure on safety and environment and increasing pressure to achieve high plant availability and to contain cost. Broadly, the approach and technique for maintenance are categorized in four groups viz. reactive maintenance, preventive maintenance, predictive maintenance and finally, the latest concept of Reliability Centered Maintenance (RCM). While the reactive maintenance is basically 'run it till it breaks' mode is an old concept for maintenance. In preventive maintenance either a time based schedule or a schedule based on that of machine run time. The goal here is to minimize system and component degradation and thus, sustain or extend the useful life of the equipment. A predictive maintenance approach strives to detect the onset of equipment degradation and differs from preventive by basing maintenance needs on the actual condition of equipment rather than some predetermined schedule. Finally, the Reliability Centered Maintenance (RCM) is the maintenance approach used when following a process that assesses equipment condition and determines the maintenance requirement in operating context. This paper brings out a case study of Reliability Centred Maintenance Technique carried out for Indian PHWR highlighting various aspects of RCM and application of the same. Though this technique of maintenance is not strictly followed presently. This can improve maintenance approach in future. (author)

    2016-03-01

    Traditional modular design methods lead to product maintenance problems, because the module form of a system is created according to either the function requirements or the manufacturing considerations. For solving these problems, a new modular design method is proposed with the considerations of not only the traditional function related attributes, but also the maintenance related ones. First, modularity parameters and modularity scenarios for product modularity are defined. Then the reliability and economic assessment models of product modularity strategies are formulated with the introduction of the effective working age of modules. A mathematical model used to evaluate the difference among the modules of the product so that the optimal module of the product can be established. After that, a multi-objective optimization problem based on metrics for preventive maintenance interval different degrees and preventive maintenance economics is formulated for modular optimization. Multi-objective GA is utilized to rapidly approximate the Pareto set of optimal modularity strategy trade-offs between preventive maintenance cost and preventive maintenance interval difference degree. Finally, a coordinate CNC boring machine is adopted to depict the process of product modularity. In addition, two factorial design experiments based on the modularity parameters are constructed and analyzed. These experiments investigate the impacts of these parameters on the optimal modularity strategies and the structure of module. The research proposes a new modular design method, which may help to improve the maintainability of product in modular design.

    The aims of this paper are (1) to identify the characteristics of maintenance service providers that directly impact maintenance service quality, using 18 independent covariables; (2) to quantify the change in risk these covariables present to service quality, measured in terms of equipment turnaround time (TAT). A survey was applied to every maintenance service provider (n = 19) for characterization purposes. The equipment inventory was characterized, and the TAT variable recorded and monitored for every work order of each service provider (N = 1,025). Finally, the research team conducted a statistical analysis to accomplish the research objectives. The results of this study offer strong empirical evidence that the most influential variables affecting the quality of maintenance service performance are the following: type of maintenance, availability of spare parts in the country, user training, technological complexity of the equipment, distance between the company and the hospital, and the number of maintenance visits performed by the company. The strength of the results obtained by the Cox model built are supported by the measure of the Rp,e(2) = 0.57 with a value of Rp,e= 0.75. Thus, the model explained 57% of the variation in equipment TAT, with moderate high positive correlation between the dependent variable (TAT) and independent variables.

    This report summarizes the accomplishments of the Laboratory Directed Research and Development (LDRD) project 26546 at Sandia, during the period FY01 through FY03. The project team visited four DoD depots that support extensive aircraft maintenance in order to understand critical needs for automation, and to identify maintenance processes for potential automation or integration opportunities. From the visits, the team identified technology needs and application issues, as well as non-technical drivers that influence the application of automation in depot maintenance of aircraft. Software tools for automation facility design analysis were developed, improved, extended, and integrated to encompass greater breadth for eventual application as a generalized design tool. The design tools for automated path planning and path generation have been enhanced to incorporate those complex robot systems with redundant joint configurations, which are likely candidate designs for a complex aircraft maintenance facility. A prototype force-controlled actively compliant end-effector was designed and developed based on a parallel kinematic mechanism design. This device was developed for demonstration of surface finishing, one of many in-contact operations performed during aircraft maintenance. This end-effector tool was positioned along the workpiece by a robot manipulator, programmed for operation by the automated planning tools integrated for this project. Together, the hardware and software tools demonstrate many of the technologies required for flexible automation in a maintenance facility.

    International Nuclear Information System (INIS)

    1 - Description of problem or function: PROMSYS is a computer system designed to automate the scheduling of routine maintenance and inspection of plant equipment. This 'programmed maintenance' provides the detailed planning and accomplishment of lubrication, inspection, and similar repetitive maintenance activities which can be scheduled at specified predetermined intervals throughout the year. The equipment items included are the typical pumps, blowers, motors, compressors, automotive equipment, refrigeration units, filtering systems, machine shop equipment, cranes, elevators, motor-generator sets, and electrical switchgear found throughout industry, as well as cell ventilation, shielding, containment, and material handling equipment unique to nuclear research and development facilities. Four related programs are used to produce sorted schedule lists, delinquent work lists, and optional master lists. Five additional programs are used to create and maintain records of all scheduled and unscheduled maintenance history. 2 - Method of solution: Service specifications and frequency are established and stored. The computer program reviews schedules weekly and prints, on schedule cards, instructions for service that is due the following week. The basic output from the computer program comes in two forms: programmed-maintenance schedule cards and programmed-maintenance data sheets. The data sheets can be issued in numerical building, route, and location number sequence as equipment lists, grouped for work assigned to a particular foreman as the foreman's equipment list, or grouped by work charged to a particular work order as the work-order list. Data sheets grouped by equipment classification are called the equipment classification list

    Full Text Available The traditional approaches for bridges maintenance is proven to be inefficient as they lead to random way of spending maintenance budget and deteriorating bridge conditions. In many cases, maintenance activities are performed due to user complaints. The objective of this paper is to develop a practical and reliable framework to manage the maintenance and repair activities of Bridges network in Egypt considering performance and budget limits. The model solves an optimization problem that maximizes the average condition of the network given the limited budget using Genetic Algorithm (GA. The main tasks of the system are bridge inventory, condition assessment, deterioration using markov model, and maintenance optimization. The developed model takes into account multiple parameters including serviceability requirements, budget allocation, element importance on structural safety and serviceability, bridge impact on network, and traffic. A questionnaire is conducted to complete the research scope. The proposed model is implemented in software, which provides a friendly user interface. The results of the framework are multi – year maintenance plan for the entire network for up to five years. A case study is presented for validating and testing the model with Data collected from “General Authority for Roads, Bridges and Land Transport” in Egypt.

Current research is inspecting the use of cannabis for many diseases, including multiple sclerosis, epilepsy, dystonia, and chronic pain. In inflammatory conditions cannabinoids improve pain in rheumatoid arthritis and:pain and diarrhea in Crohn's disease. Despite their therapeutic potential, cannabinoids are not free of side effects including psychosis, anxiety, paranoia, dependence and abuse. Controlled clinical studies investigating the therapeutic potential of cannabis are few and small, whereas pressure for expanding cannabis use is increasing. Currently, as long as cannabis is classified as an illicit drug and until further controlled studies are performed, the use of medical cannabis should be limited to patients who failed conventional better established treatment.

    In this paper, the failure mechanism of electronic equipment was analysed. Aiming at the limitation of traditional maintenance modes, moderu maintenance strategy was put forward on the basis of reliability-centered maintenance (RCM) combined with condition-based maintenance (CBM)aud maintenance efficiency review (MER). A maintenance management information system was constructed for electronic equipment for the purpose of failure analysis, reliability evaluation, and maintenance decisions such as time, mode, and plan. The best maintenance time could be predicted with failure analysis and reliability evaluation, which was mainly influenced by environmental stress. Suitable maintenance modes should be determined fiom equipment importance, failure aftereffect, maintenance condition, and economical power so as to ensure equipment reliability and decrease the requirement of the maintenance source.

  10. Dynamic shared state maintenance in distributed virtual environments

    Science.gov (United States)

    Hamza-Lup, Felix George

    Advances in computer networks and rendering systems facilitate the creation of distributed collaborative environments in which the distribution of information at remote locations allows efficient communication. Particularly challenging are distributed interactive Virtual Environments (VE) that allow knowledge sharing through 3D information. The purpose of this work is to address the problem of latency in distributed interactive VE and to develop a conceptual model for consistency maintenance in these environments based on the participant interaction model. An area that needs to be explored is the relationship between the dynamic shared state and the interaction with the virtual entities present in the shared scene. Mixed Reality (MR) and VR environments must bring the human participant interaction into the loop through a wide range of electronic motion sensors, and haptic devices. Part of the work presented here defines a novel criterion for categorization of distributed interactive VE and introduces, as well as analyzes, an adaptive synchronization algorithm for consistency maintenance in such environments. As part of the work, a distributed interactive Augmented Reality (AR) testbed and the algorithm implementation details are presented. Currently the testbed is part of several research efforts at the Optical Diagnostics and Applications Laboratory including 3D visualization applications using custom built head-mounted displays (HMDs) with optical motion tracking and a medical training prototype for endotracheal intubation and medical prognostics. An objective method using quaternion calculus is applied for the algorithm assessment. In spite of significant network latency, results show that the dynamic shared state can be maintained consistent at multiple remotely located sites. In further consideration of the latency problems and in the light of the current trends in interactive distributed VE applications, we propose a hybrid distributed system architecture for

    The International Society for Medical Publication Professionals (ISMPP) is an independent, nonprofit professional association with members from the pharmaceutical, medical device, and biotechnology industries; publication planning and medical communications companies; academia; and medical journal staffs, including editors and publishers. ISMPP's mission is to support the educational needs of medical publication professionals by providing a forum to facilitate awareness and development of best practices in publication planning and implementation, and fostering consensus policies related to medical publishing. This position statement reflects our concern about the current climate of mistrust regarding the use of professional medical writers in the preparation of manuscripts. We acknowledge the skills and training of medical writing professionals and support their role in working with research teams to develop clear and concise manuscripts in a timely fashion. Further, we support complete and transparent disclosure of the role of the medical writer and the source of funding for the writing initiative in order to build awareness of, and trust in, the appropriate use of medical writing professionals. ISMPP endorses use of the contributorship model, which offers detailed information on the roles of all who participated in planning, conducting, developing, and publishing medical research. Further, we propose that this model be integrated into the standard operating procedures of the diverse organizations that comprise our membership because the responsibility for authorship disclosure is shared by sponsors, authors, study investigators, and medical writers. Finally, we commend the many organizations that have worked to increase recognition and understanding of the legitimate role of the medical writer, and are eager to work in concert with them to ensure the rigorous maintenance of all ethical standards for reporting the results of medical research.

  12. Performance-based inspection and maintenance strategies

    Energy Technology Data Exchange (ETDEWEB)

    Vesely, W.E.

    1995-04-01

    Performance-based inspection and maintenance strategies utilize measures of equipment performance to help guide inspection and maintenance activities. A relevant measure of performance for safety system components is component unavailability. The component unavailability can also be input into a plant risk model such as a Probabilistic Risk Assessment (PRA) to determine the associated plant risk performance. Based on the present and projected unavailability performance, or the present and projected risk performance, the effectiveness of current maintenance activities can be evaluated and this information can be used to plan future maintenance activities. A significant amount of information other than downtimes or failure times is collected or can be collected when an inspection or maintenance is conducted which can be used to estimate the component unavailability. This information generally involves observations on the condition or state of the component or component piecepart. The information can be detailed such as the amount of corrosion buildup or can be general such as the general state of the component described as {open_quotes}high degradation{close_quotes}, {open_quotes}moderate degradation{close_quotes}, or {open_quotes}low degradation{close_quotes}. Much of the information collected in maintenance logs is qualitative and fuzzy. As part of an NRC Research program on performance-based engineering modeling, approaches have been developed to apply Fuzzy Set Theory to information collected on the state of the component to determine the implied component or component piecepart unavailability. Demonstrations of the applications of Fuzzy Set Theory are presented utilizing information from plant maintenance logs. The demonstrations show the power of Fuzzy Set Theory in translating engineering information to reliability and risk implications.

    2014-06-01

    U.S. graduate medical education (GME) training institutions are under increasing scrutiny to measure program outcomes as a demonstration of accountability for the sizeable funding they receive from the federal government. The Accreditation Council for Graduate Medical Education (ACGME) is a potential agent of measuring GME accountability but has no interaction with physicians after residency training is completed. American Board of Medical Specialty (ABMS) member boards interact with physicians throughout their careers through maintenance of certification (MOC) and are a potential source of valuable data on physician competency and quality of care, both of which could be used to measure GME accountability.The authors propose that ABMS boards and the ACGME deepen their existing relationship to better assess residency training outcomes. ABMS boards have a wealth of data on physicians collected as a by-product of MOC and business operations. Further, many ABMS boards collect practice demographics and scope-of-practice information through MOC enrollment surveys or recertification examination questionnaires. These data are potentially valuable in helping residencies know what their graduates are doing in practice. Part 4 of MOC generally involves assessment of the quality of care delivered in practice, and ABMS boards could share these deidentified data with the ACGME and residency programs to provide direct feedback on the practice outcomes of graduates.ABMS member boards and the ACGME should broaden their long-standing relationship to further develop shared roles and data-sharing mechanisms to better inform residencies and the public about GME training outcomes.

    Full Text Available :The majority of the industrial machine components have to satisfy to the requirements of the high quality and incessantly increasing; so the machines maintaining in good state during the production has became a fundamental point for a product or a company success. Through the measure of the predictive maintenance, it is possible to satisfy these complex requirements with success and to reduce the costs of maintenance. However, an optimization of the maintenance is realized by a continued monitoring of degradation, by way of a control system on line “On Line”, which can respond to industrial imperatives and which provides to define just the necessary at the level of interventions, “The machine can’t be serviced except if only its state requires.”For an effective maintenance, it takes precise and reliable measures. Nevertheless, the experience has shown that the vibratory measure is the most reliable parameter that gives the precociously and with a best ways the deterioration state of a turnable machine. It provides to identify the efforts as soon as they appear, before of an irreversible damage, it also provides, after analysis, to deduce the origin and to estimate the breakdown risks.In this context, a study had done inside a workshop of a phosphoric office, which adopt a continued surveillance (On-Line, in the hope of doing an optimal process of a conditional maintenance which can be developed in time toward an idealized by a vibratory indicator accomplishing satisfactory results.

    In order to improve software maintenance processes, we first need to be able to characterize and assess them. These tasks must be performed in depth and with objectivity since the problems are complex. One approach is to set up a measurement-based software process improvement program specifically aimed at maintenance. However, establishing a measurement program requires that one understands the problems to be addressed by the measurement program and is able to characterize the maintenance environment and processes in order to collect suitable and cost-effective data. Also, enacting such a program and getting usable data sets takes time. A short term substitute is therefore needed. We propose in this paper a characterization process aimed specifically at maintenance and based on a general qualitative analysis methodology. This process is rigorously defined in order to be repeatable and usable by people who are not acquainted with such analysis procedures. A basic feature of our approach is that actual implemented software changes are analyzed in order to understand the flaws in the maintenance process. Guidelines are provided and a case study is shown that demonstrates the usefulness of the approach.

  16. Intelligence System for Software Maintenance Severity Prediction

    Full Text Available The software industry has been experiencing a software crisis, a difficulty of delivering software within budget, on time, and of good quality. This may happen due to number of defects present in the different modules of the project that may require maintenance. This necessitates the need of predicting maintenance urgency of the particular module in the software. In this paper, we have applied the different predictor models to NASA five public domain defect datasets coded in C, C++, Java and Perl programming languages. Twenty one software metrics of different datasets and Java Classes of thirty five algorithms belonging to the different learner categories of the WEKA project have been evaluated for the prediction of maintenance severity. The results of ten fold cross validation are recorded in terms of Accuracy, Mean Absolute Error (MAE and Root Mean Squared Error (RMSE for different project datasets. The results show that logistic model Trees (LMT and Complimentary Naïve Bayes (CNB based Model provide a relatively better prediction consistency compared to other models and hence, can be used for the maintenance severity prediction of the software. The developed system can also be used for analysis and to evaluate the influence of different factors on the maintenance severity of different software project modules.

  17. Demonstration of reliability-centered maintenance

    International Nuclear Information System (INIS)

    On March 9, 1988 the Southern California Edison Company was selected by the Electric Power Research Institute as one of two utilities to perform a large scale Reliability-Centered Maintenance demonstration project to be co-funded by EPRI and SCE. The overall objective of this project is to demonstrate that RCM can be effectively performed in a plant environment leading to improved overall unit performance. The objective of SCE is to optimize the existing Preventive Maintenance program at San Onofre Nuclear Generating Station Unit 2. The successful achievement of this goal requires the active involvement and the cooperative efforts of the operations and Maintenance Support, Maintenance, Station Technical, and Operations Divisions. This report describes progress to date in the RCM core elements such as system selection, applications of the RCM methodology to the systems selected, lessons learned, course corrections, implementation of the RCM recommendations, results achieved, and development of a living program. The overall project involves analysis of approximately twelve to sixteen systems. To date, six have been completed and two are underway. The results to date indicate a significant payback in maintenance cost reduction, even with the expansion of some PM activities for identified critical failure modes. 7 refs., 12 figs., 7 tabs

  18. Probabilistic methods for maintenance program optimization

    International Nuclear Information System (INIS)

    In today's regulatory and economic environments, it is more important than ever that managers, engineers, and plant staff join together in developing and implementing effective management plans for safety and economic risk. This need applied to both power generating stations and other process facilities. One of the most critical parts of these management plans is the development and continuous enhancement of a maintenance program that optimizes plant or facility safety and profitability. The ultimate objective is to maximize the potential for station or facility success, usually measured in terms of projected financial profitability, while meeting or exceeding meaningful and reasonable safety goals, usually measured in terms of projected damage or consequence frequencies. This paper describes the use of the latest concepts in developing and evaluating maintenance programs to achieve maintenance program optimization (MPO). These concepts are based on significant field experience gained through the integration and application of fundamentals developed for industry and Electric Power Research Institute (EPRI)-sponsored projects on preventive maintenance (PM) program development and reliability-centered maintenance (RCM)

    Atrial fibrillation (AF) is the most common rhythm disturbance seen in clinical practice, and its prevalence and incidence are rising rapidly as the population ages with its attendant complications. Management of AF involves anticoagulation, and fortunately new drugs for long-term anticoagulation are now available. Maintenance of sinus rhythm, though intuitively better than rate control strategy, has not been shown to offer mortality benefit. Still, maintenance of sinus rhythm is considered an appropriate therapeutic strategy when symptoms are not adequately controlled with rate control. Though significant advances have been made in ablation techniques for AF, pharmacological therapy is still the first line of treatment for rate control and maintenance of sinus rhythm, given ease of use, noninvasive nature, and limited experience with catheter-based ablation techniques. Class IC and III agents (Vaughan Williams classification) form the backbone for pharmacological maintenance of sinus rhythm. Dronedarone, a recently approved class III agent, provides a significant advance because of its relatively safe side effect profile. Currently drugs with selective atrial channels blocking properties, like Vernakalant, are being tested in trials and may provide an opportunity to maintain sinus rhythm with limited toxicity. Large trials are also being conducted to better define the efficacy of catheter-based ablation strategy as first-line treatment. Here, we review the current status of commonly used antiarrhythmic medications for the maintenance of sinus rhythm in AF.

  13. Modeling and Analysis of Complex Equipment Maintenance Dynamics

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    An equipment maintenance system is naturally a complex dynamical system. The effective maintenance management must be based on the knowledge of the system's intrinsic dynamics. And the structure of the maintenance system determines its behavior. This paper analyzes the basic structures and elements of a maintenance system for complex multi-components equipment. The maintenance system is considered as a dynamic system whose behavior is influenced by its structure's feedback and interaction, and the system's available resources. Building the dynamical model with Simulink, we show some results about the maintenance system's nonlinear dynamics, which are never given by stochastic process methods. The model can be used for understanding and determining maintenance system behavior, towards which operational adjustments of maintenance infrastructure, precise prediction of maintenance requirements and timely supply of maintenance resources can be made in a more informed way.

  16. Job performance aids: Human factoring maintenance procedures

    International Nuclear Information System (INIS)

    Job performance aids (JPAs) are human factors engineering techniques used to strengthen operating, maintenance, and engineering procedures. They are not a new concept, but one whose time has come. This paper focuses on the application of JPAs to maintenance procedures. Job performance aids research originates from US Department of Defense (DOD) efforts, primarily in maintenance-oriented tasks. While at Connecticut Yankee power plant, the authors, an instructional consultant, and the training manager were investigating ways to enhance training effectiveness. Based on historic research efforts, there is strong evidence that JPAs have the potential to improve human performance and realize additional benefits of reduced training time and should be incorporated into the training time and should be incorporated into the training curriculum

    Collection and analysis of data are reported that concern the reliability and maintenance experience of flight control system electronics currently in use on passenger carrying jet aircraft. Two airlines B-747 airplane fleets were analyzed to assess the component reliability, system functional reliability, and achieved availability of the CAT II configuration flight control system. Also assessed were the costs generated by this system in the categories of spare equipment, schedule irregularity, and line and shop maintenance. The results indicate that although there is a marked difference in the geographic location and route pattern between the airlines studied, there is a close similarity in the reliability and the maintenance costs associated with the flight control electronics.

  18. Open Data: Reverse Engineering and Maintenance Perspective

    CERN Document Server

    Kienle, Holger M

    2012-01-01

    Open data is an emerging paradigm to share large and diverse datasets -- primarily from governmental agencies, but also from other organizations -- with the goal to enable the exploitation of the data for societal, academic, and commercial gains. There are now already many datasets available with diverse characteristics in terms of size, encoding and structure. These datasets are often created and maintained in an ad-hoc manner. Thus, open data poses many challenges and there is a need for effective tools and techniques to manage and maintain it. In this paper we argue that software maintenance and reverse engineering have an opportunity to contribute to open data and to shape its future development. From the perspective of reverse engineering research, open data is a new artifact that serves as input for reverse engineering techniques and processes. Specific challenges of open data are document scraping, image processing, and structure/schema recognition. From the perspective of maintenance research, mainten...

  19. The Modern Approach to Industrial Maintenance Management

    Directory of Open Access Journals (Sweden)

    Vasile DEAC

    2010-01-01

    Full Text Available The maintenance activity isn’t a purpose in itself, it’s a necessity of which "the production suffers" and the financial agent “considers too expensive”. It often exists a conflict between the production units and the maintenance department, not only for a short term, but, sometimes, for a long term, imposing a rigorous definition of each person’s responsibilities. Considering the mutations in the industrial equipments’ technical complexity and the accidental failures’ catastrophic consequences from the economic and/or social point of view, it should be assigned a new dimension to the maintenance activity. One of the imperatives imposed to this action is represented by modern means of informing through the maintenance’s operational computerization.
