    Full text: United States nuclear power plants are initially licensed for a period of 40-years. The 40-year term, which was established by the Atomic Energy Commission in the 1950s, is believed to be based on engineering judgement and is consistent with the typical amortization schedule for purchasing fossil power plants. Under 10 CFR Part 54, the license renewal rule, additional terms of 20-years may be obtained through the preparation of a license renewal application that must be reviewed and approved by the Nuclear Regulatory Commission (NRC). The license renewal rule requires that applicants perform ageing management reviews on passive long-lived structures and components to demonstrate that ageing will be managed during the period of extended operation (i.e., additional 20 years of operation). ageing of active components, which are excluded from 10 CFR Part 54, is accomplished through the Maintenance Rule, 10 CFR Part 65, using performance-based monitoring. The license renewal rule, 10 CFR Part 54, was initially published in 1991. After significant interaction with the nuclear industry from 1991 through 1994, the NRC revised the rule in 1995 to focus on passive long-lived structures and components. In 1998, the first two applications for license renewal were submitted to the NRC by Baltimore Gas and Electric for the two-unit Calvert Cliffs nuclear power plant and by Duke Energy for the three-unit Oconee nuclear power plant. In March 2000, the NRC approved the application for the two-unit Calvert Cliffs nuclear power plant for an additional 20 years. Two months later, the NRC approved the renewal of the operating licenses for the three-unit Oconee nuclear station. The NRC completed these reviews in a timely, predictable, and stable manner. As of February 2002, the NRC has approved renewal of operating licenses for eight nuclear units and has applications under review for 15 more units. Twelve additional companies have notified the NRC of their intention to seek

    The purpose of this work is to determine the structures included within the scope of license renewal based on the performance of the functions and select those intended for aging management review; one purpose is to show the methodology used to establish the structure and structural components that are subject to a review of aging management, within the framework of license renewal rule. This is through the application of different types of structures and structural components related and unrelated to safety located in the rooms of the reactor building where there are components of the reactor core isolation cooling system (Rcic), these structures are poured concrete, concrete block, structural steel, shielding walls, attached metal, pile foundations, etc.; other non- security related , such as: 1) inherent characteristics not related to security that protect the equipment related to the safety of the missiles, that is, walls, low walls, dikes, doors, etc., which also provide flood barriers to structures, systems and components related to safety, 2 ) whipping restrictions on non- security, shields mitigation jet, vent panels , etc. that are designed and installed to protect equipment related with the safety of the effects of a broken line of high energy. Only rooms where there are components of the Rcic 68 structures within the scope were identified. (Author)

  3. Review: Management of adnexal masses: An age-guided approach ...

    African Journals Online (AJOL)

    Adnexal masses in different age groups may need different management approaches. By elimination of the type of mass that is less likely in a specific age group one can identify the most prevalent group which can guide management. Most important of all, the probability of malignancy must either be identified or ruled out.

    According to the requirements of NNSA, for Chinese operational NPPs periodical safety review (PSR) should be carried out every 10 years. Ageing management is one of the important safety factors to be reviewed. Entrusted by Qinshan Nuclear Power Plant (QNPP), Shanghai Nuclear Engineering Research and Design Institute (SNERDI) carried out the ageing management review (AMR), as a part of the first PSR of QNPP, from 2001 to 2003. This paper summarizes the methodology of the AMR process, including screening of critical components and structures, identification of main ageing mechanisms and their indicators and the tabulated review process, etc. 15 components and structures, hereafter referred as equipment, were selected as review objects based on their significance of safety, replaceability and cost-benefit considerations. To these objects, the main ageing mechanisms and relevant ageing indicators were identified according to specific working and environmental condition, design and manufacture information, operation and maintenance history, etc. The review can be divided into two parallel parts, the review for specific equipment and the review for overall management procedures and their implementation. To typical components, such as RPV and SG, fatigue analysis based on operational transient accounting was carried out to observe the actual safety margins. Through the review, the weaknesses in ageing management and potential threats to structural integrity were identified and thus continued improvement can be made in the next period of 10 years.

    Gris Cruz, Magdalena; Arganis, Carlos R.J.; Medina Almazan, A. Liliana

    2012-01-01

    In the present paper, for both units of Laguna Verde Nuclear Power Plant (LVNPP), the Ageing Management Review of the reactor pressure Vessel was carried out, including the identification of the intended functions, the materials and the environments. The evaluation of the ageing effect/mechanism and the Aging management programs currently implemented were prepared. The most important aging effects/ mechanisms are: loss of fracture toughness due to neutron irradiation embrittlement, fatigue, stress corrosion cracking (SCC), general corrosion and erosion-corrosion. The neutron irradiation embrittlement is managed by the reactor vessel materials surveillance program. The fatigue is a Time Limited Aging Analysis (TLAA), for which is necessary to calculate some fatigue usage factors. SCC is managed by, the In service inspections (ISI) program, but also by the Water Chemistry program, including, currently, On Line Noble Chem. The water chemistry program also manages General Corrosion and erosion-corrosion. The results were compared with the GALL report. (author)

  7. Regulatory instrument review: Management of aging of LWR [light water reactor] major safety-related components

    1990-10-01

    This report comprises Volume 1 of a review of US nuclear plant regulatory instruments to determine the amount and kind of information they contain on managing the aging of safety-related components in US nuclear power plants. The review was conducted for the US Nuclear Regulatory Commission (NRC) by the Pacific Northwest Laboratory (PNL) under the NRC Nuclear Plant Aging Research (NPAR) Program. Eight selected regulatory instruments, e.g., NRC Regulatory Guides and the Code of Federal Regulations, were reviewed for safety-related information on five selected components: reactor pressure vessels, steam generators, primary piping, pressurizers, and emergency diesel generators. Volume 2 will be concluded in FY 1991 and will also cover selected major safety-related components, e.g., pumps, valves and cables. The focus of the review was on 26 NPAR-defined safety-related aging issues, including examination, inspection, and maintenance and repair; excessive/harsh testing; and irradiation embrittlement. The major conclusion of the review is that safety-related regulatory instruments do provide implicit guidance for aging management, but include little explicit guidance. The major recommendation is that the instruments be revised or augmented to explicitly address the management of aging

    The phenomenon of an ageing population is being experienced globally, as countries struggle to change and improve residential models of care and provide services to the elderly. The role of the registered nurse (RN) is considered crucial to the clinical governance and management of care given. To date, however, no systematic review has examined the RN's experience in leadership and management. The objective of this review is to critically appraise, synthesise and present best available evidence on the experiences of RNs as clinical leaders and managers in residential aged care facilities. This review considered qualitative research papers that addressed the experiences of RNs as clinical leaders and managers in residential aged care facilities. Participants of interest were RNs, nurse leaders, nurses holding registration and or regulation under a board of nursing, nurses working in residential aged care and long-term care facilities. The diversity and use of language to describe nurses' roles and models of care for the elderly care environment were considered in the review. The search strategy sought to find both published studies and papers, limited to the English language and published between January 1997 and February 2011. An initial limited search was done in Medical Literature Analysis and Retrieval System Online (MEDLINE) and Cumulative Index to Nursing and Allied Health Literature databases to identify the key words contained in the title or abstract and index terms used to describe the relevant terms in the article. A second extensive search was undertaken and extended to other relevant databases using all identified keywords and index terms. The third step involved searching reference lists and bibliographies of chosen articles for additional studies. Each paper was assessed by two independent reviewers for methodological quality prior to inclusion in the review using an appropriate critical appraisal instrument from the System for the Unified Management

    1995-01-01

    As of December 1994, 34 PWR 900 MW units and 20 PWR 1300 MW units are in operation, giving a total of more than 57,000 MW installed. These units are standardized and provide 75 percent of the French electrical output. They were all brought into service within a 15 year period. Considering the situation of those units in the production capacity, it is hardly necessary to point out the importance of a correct assessment of their potential lifetime (plant life management). This plant life management includes: technical aspects, safety aspects, economic aspects, operational aspects, national and international environment

    The results of Stage 2 of the Regulatory Instrument Review are presented in this volume. Selected regulatory instruments, such as the Code of Federal Regulations (CFR), US Nuclear Regulatory Commission (NRC), Regulatory Guides, and ASME Codes, were investigated to determine the extent to which these regulations apply aging management to selected safety-related components in nuclear power plants. The Regulatory Instrument Review was funded by the NRC under the Nuclear Plant Aging Research (NPAR) program. Stage 2 of the review focused on four safety-related structures and components; namely, cables, containment and basemat, reactor coolant pumps, and motor-operated valves. The review suggests that the primary-emphasis of the regulatory instruments was on the design, construction, start-up, and operation of a nuclear power plant, and that aging issues were primarily addressed after an aging-related problem was recognized. This Stage 2 review confirms the results of the prior review; (see Regulatory Instrument Review: Management of Aging of LWR Major Safety-Related Components NUREG/CR-5490. The observations indicate that the regulations generally address management of age-related degradation indirectly. Specific age-related degradation phenomena frequently are dealt with in bulletins and notices or through generic issues, letters, etc. The major recommendation of this report, therefore, is that the regulatory instruments should more directly and explicitly address the aging phenomenon and the management of the age-related degradation process

    This is the final report of the second year study. Based on the first year study, proposal of revised guidelines, analysis of revised or newly issued IAEA safety guides and reference guidelines of developed countries, and proposal of detailed guidelines of aging management in PSR have been performed in the second year study. The summary of results in the study so far can be summarized as below, overall view on PSR and idea of effective domestic application were leaded through additional investigation and comparison of legal basis, experiences and current status of PSR implementation among the countries having operating NPPs including Korea. Strategies of adequate application of PSR are roughly reevaluated and totally reestablished in summary from the analysis in factor by factor basis of PSR implementation experience in foreign countries and background of IAEA guidelines. Models and draft framework of PSR report in the first year study were summarized and reevaluated, and structure and outline options of PSR guidelines for judging the PSR report are newly proposed with comparison of their strengths and weaknesses based on the first year study. Among the opt ions, guidelines framework equivalent to the PSR report was picked up as the best. For the judgement of aging management, the most appropriate one was chosen for the detailed judgement of aging management review in our PSR being based on the Standard Review Plan for License Renewal (SRP-LR) in United States considering potential future usage in the judgement for continued operation of old NPP at the time of expiration of its design life. A draft PSR guidelines is prepared and attached by revision of basic guidelines issued in 2000, considering the issues discussed for the draft revision of IAEA PSR guide, the draft IAEA document about 'experience of PSR implementation of member states', and the characteristics of Hungarian PSR Guidelines.

    Ageing of Systems, Structures and Components (SSCs) is a natural process and sets in along with the construction and commissioning of plants in spite of best design provisions and maintenance practices. Plant operators and maintainers need to plan and take measures against ageing degradation of SSCs to maintain the high standards of safety. As safety is a continuously evolving phenomenon, incorporating safety upgrades from time to time and carrying out ageing management towards improved safety for research and power reactors is very important. Cirus research reactor which was commissioned in 1960 and Tarapur Atomic power station which was commissioned in 1969 are two such examples of older generation nuclear plants in India which are presently undergoing extensive refurbishment towards implementation of ageing management programme. The 40 MWt Cirus Research Reactor located at the Bhabha Atomic Research Centre, Mumbai, is a vertical closed tank type reactor with natural uranium as fuel, demineralised light water as primary coolant, heavy water as moderator and graphite as reflector. The reflector and the thermal shields are cooled by reactor building ventilation system. Sea water is used as secondary coolant. The reactor vessel is made of aluminium and has 199 lattice tubes rolled into top and bottom tube sheets. It has an expansion joint between the top tube sheet and the shell to allow for thermal expansion. The reactor operated very efficiently till early nineties after which the ageing degradation of SSCs started affecting the reactor operation. Plant availability factor showed a declining trend due to frequent breakdown of equipment. Detailed performance review was carried out for various equipment and a list of equipment that needed replacement was prepared. Equipment, for which availability of spares was becoming difficult due to obsolescence, were also included in this list. Detailed ageing studies were then taken up on various SSCs. The SSCs were

    The present paper, describes the experiences in the Technical Cooperation Project with the IAEA MEX 4/058 related with the Licensed Renewal Process, according with 10 CFR 54, NEI-95-10, NUREG 1800 and NUREG 1801. A domestic data base using Microsoft ACCESS was made following the methodology suggest by 10 CFR 54, and the Reactor Core Isolation Cooling (RCIC) System was selected like a pilot system. The mechanical components within the scope of license renewal and their intended functions were selected and the components subject to Aging Management Review (AMR) were identified. Commodities groups of similar material, environment and intended function were used and the main Ageing Mechanisms were identified. The results were compared with the NUREG 1801 rev. 2 experiences and the possible AMP was addressed. In the case of Laguna Verde Nuclear Power Plant (LVNPP) U1, some of these programs are according with the Generic Aging Lesson Learned of NUREG 1801, while others AMP require modifications. It is important to mention that the application of this methodology will support activities related with long term operation in LVNPP. (author)

    Age-related macular degeneration (AMD), the most important cause of vision loss in elderly people, is a degenerative disorder of the central retina with a multifactorial etiopathology. AMD is classified in dry AMD (d-AMD) or neovascular AMD depending on the presence of choroidal neovascularization. Currently, no therapy is approved for geographic atrophy, the late form of d-AMD, because no treatment can restore the damage of retinal pigment epithelium (RPE) or photoreceptors. For this reason, all treatment approaches in d-AMD are only likely to prevent and slow down the progression of existing atrophy. This review focuses on the management of d-AMD and especially on current data about potential targets for therapies evaluated in clinical trials. Numerous examinations are available in clinics to monitor morphological changes in the retina, RPE and choroid of d-AMD patients. Fundus autofluorescence and optical coherence tomography (OCT) are considered the most useful tools in the diagnosis and follow-up of d-AMD alterations, including the monitoring of atrophy area progression. Instead, OCT-angiography is a novel imaging tool that may add further information in patients affected by d-AMD. Several pathways, including oxidative stress, deposits of lipofuscin, chronic inflammation and choroidal blood flow insufficiency, seem to play an important role in the pathogenesis of d-AMD and represent possible targets for new therapies. A great number of treatments for d-AMD are under investigation with promising results in preliminary studies. However, only few of these drugs will enter the market, offering a therapeutic chance to patients affected by the dry form of AMD and help them to preserve a good visual acuity. Further studies with a long-term follow-up would be important to test the real safety and efficacy of drugs under investigation.

    The paper introduced the ageing management of CARR, including the ageing management system, instances of ageing components, difficulties we met and follow up plan, and put forward some suggestions on strengthening and promoting ageing management. We hope to enhance international exchange and collaboration. It is a great challenge to do research on how to manage ageing effectively in the beginning of life, but it will enhance the safety of reactor operation, extend the life of the reactor and improve the quality of operation, making this work very meaningful.

  16. SALTO guidelines. Guidelines for peer review of long term operation and ageing management of nuclear power plants

    International Nuclear Information System (INIS)

    2008-01-01

    The average age of nuclear power plants (NPPs) connected to the grid worldwide is increasing. About 20% of all the power reactors operating worldwide have been in operation for more than 30 years, and almost 50% have been in operation for 20 to 30 years, while a rather limited number of new NPPs are being put into operation. In view of this trend, many countries are giving a high priority to continuing the operation of NPPs beyond the time frame originally anticipated (e.g. 30 or 40 years). Long term operation (LTO) for NPPs is operation beyond the established time frame originally set forth by the license term, design limits, standards or regulations. LTO needs to be justified by a safety assessment considering life limiting processes and features for structures, systems and components. Proper and safe LTO is based on the experience and practices of various countries in areas such as plant license renewal, life extension, continued operation and life management. Other activities, including periodic safety review, ageing management and plant modification, are also relevant to LTO. Ageing management of an NPP is an important activity that must be considered before and in conjunction with the decision to enter LTO. Ageing management of NPPs deals with the physical ageing of structures, systems and components (SSCs) that can result in the degradation of their performance characteristics. Thus ageing management helps ensure that SSCs important to safety remain capable of performing their required safety functions. An effective ageing management programme (AMP) is a key element of the safe and reliable operation of NPPs during the originally planned time frame originally planned for their operation, as well as for the period of LTO. In order to assist Member States in managing ageing effectively, the IAEA is developing related safety standards and guidance publications. International peer review is a useful tool for Member States to exchange experience, learn from each

    As a part of Periodic Safety Review Program (PSR) NEK will review and perform some activities related to Equipment Qualification (EQ) and Aging Management Program (AMP). (EQ) and AMP are safety factors, which need to be assessed during PSR. The goal of PSR and AMP is to determine aging effects and give the conclusion whether the plant has been managed to control aging related degradations and that safety margins are maintained. The parallel goal is also to establish AMP for future plant operation and provide basis for possible Life Extension Program. NEK will develop NEK Aging and Life Cycle Management Program, similar by format and content to one determined by License Renewal program. The bases are in 10CFR54, and NEI 95-10 Industry Guidelines for 10 CFR 54 implementation. The process of establishment the AMP is to be done in two steps. The first step is dealing with SSC's (Systems Structures and Components) scoping and screening and identification of TLAA's (Time Limited Aging Analyses). That means, that a database of all SSC's and TLAA's will be created and then evaluated within AMP program. Based on the scope in first phase an evaluation will be performed in step two. NEK will maintain AMP program as a living program that may be also used for Life Extension and Life Cycle Management. This paper will present and describe AMP, scoping and screening process and the results achieved through the first phase of the project.(author)

    2013-08-15

    In February 2013, there are 50 units of commercial nuclear power plants (NPPs) in Japan. We enter into a period that 20 units of them are operating for more than 30 years. Currently, regulation imposes utilities to conduct ageing technical evaluations of each unit before operation of 30 years from the commissioning, to develop the long term maintenance management policy for next 10 years and to submit to the regulatory authority the policy with the report on ageing management technical evaluation (AMTE) for each NPP. It is necessary for regulatory side to develop technical information bases incorporating latest technical knowledge as operating experiences in domestic and abroad on ageing of the plants necessary to conduct reviews of AMTE for each unit. Based on these standpoints, technical information bases investigations have been conducted from the viewpoints of material degradation of ageing NPPs. In order to develop scientific regulator judgment bases related to ageing management (AM) and long-term operation (LTO), investigations on latest information on ageing management in domestic and abroad are conducted and a set of documents including technical evaluation review manuals necessary to conduct AMTE are prepared. To utilize the results of the investigations for ageing technical evaluation, database including latest information related to AM and LTO are developed, ran and operated. In addition, investigations related to Fugen nuclear plant, under decommissioning plants, investigations on mechanism of stress corrosion cracking (SCC), thermal ageing and preventive technologies for SCC, detection and diagnosis technology for ageing degradation and condition monitoring technology are performed to validate and confirm effectiveness of the technologies.

    The aspects of plant ageing management (AM) gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. Besides national activities there are a number of international activities in particular under the umbrella of the IAEA, the OECD and the EU. The paper discusses the process, procedure and database developed for Slovenian Nuclear Safety Administration (SNSA) surveillance of ageing process of Nuclear power Plant Krsko.(author)

    2012-01-01

    Worldwide, due to the age of the majority of nuclear generating stations significant attention is being paid to the condition of the major components, e.g., reactor, steam generator, turbine generator, transformer, etc., with respect to relicensing and life extension. However, there is recognition that cable systems are critical to the safe, reliable and economic operation of nuclear power plants. Consequently, there is great interest in ageing management of low and medium voltage cables in the nuclear environment. Successful implementation of such programs requires an understanding of how the materials associated with cables and their accessories behave under normal operating and accident conditions. However, there is also a great need to determine the actual condition of the materials and systems in order to make rational decisions on whether or not to replace cables to ensure long term assurance of reliable operation. This proposed contribution describes an approach to cable ageing management of low and medium voltage cables based on measurements of material and electrical properties obtained in the laboratory and in the field. The effectiveness of various chemical, mechanical and electrical test methods are discussed in the context of, • Cable configuration, i.e., low or medium voltage, shielded or unshielded • Material type, i.e., PVC, XLPE, EPR, etc., • Ageing stress, i.e., electrical, thermal, radiation, thermal plus radiation, etc. These factors are key to identifying the most appropriate test method (or methods) to enable understanding of the current condition of the cable. While electrical test methods, e.g., ac withstand testing, partial discharge and various dielectric loss measurement techniques have been found effective for medium voltage cables, they are of very limited use on low voltage cables that constitute the majority of cables in nuclear power plants. This limited effectiveness is due to the lack of a well defined ground plane that is a

  4. Management of research reactor ageing

    International Nuclear Information System (INIS)

    1995-03-01

    As of December 1993, about one quarter of the operating research reactors were over 30 years old. The long life of research reactors has raised some concern amongst research reactor operators, regulators and, to some extent, the general public. The International Atomic Energy Agency commenced activities on the topic of research reactor ageing by appointing an internal working group in 1988 and convening a Consultants Meeting in 1989. The subject was also discussed at an international symposium and a regional seminar held in 1989 and 1992 respectively.

    As of December 1993, about one quarter of the operating research reactors were over 30 years old. The long life of research reactors has raised some concern amongst research reactor operators, regulators and, to some extent, the general public. The International Atomic Energy Agency commenced activities on the topic of research reactor ageing by appointing an internal working group in 1988 and convening a Consultants Meeting in 1989. The subject was also discussed at an international symposium and a regional seminar held in 1989 and 1992 respectively. A draft document incorporating information and experience exchanged at the above meetings was reviewed by a Technical Committee Meeting held in Vienna in 1992.

    Operational experience shows that excellent plant safety and excellent performance go hand in hand, and that they are achieved by effective leadership and management that includes a unified approach to safety and production. This is also applicable to ageing management. Effective ageing management leads to both enhanced plant safety and enhanced performance and is a prerequisite for long service life. The IAEA project on Safety Aspects of NPP Ageing has produced since 1990 a comprehensive set of programmatic and component specific guidelines on managing ageing, while providing an interactive environment for information exchange and co-operation among practitioners, and has assisted Member States in the application of the guidelines through the provision of training and advice. The objective of the CD-ROM is to preserve the IAEA's guidance on ageing management and to facilitate its retrieval, updating, extension and dissemination in order to help increase the effectiveness of ageing management at nuclear power plants

    Systematic and effective control of age-related degradation of safety-related components, systems, and structures in nuclear power plants (NPPs) is an important challenge to plant operators. Several data bases, available to provide guidance on aging management, are summarized. However, the ultimate consideration is: How effectively is aging management being implemented at individual plants? Illustrated here is a specific strategy that served to develop the technical data base for the Nuclear Plant Aging Research Program. The strategy is comprehensive, systematic, and adaptable. Effective aging management at NPPs could be facilitated by a parallel strategy. The elements of a strategy are suggested

    Approximately 20% of the present electric generating capacity in the United States is supplied by nuclear power plants and may be retired due to initial license expiration between the years 2002 and 2030. One of the recommended actions for implementing the National Energy Strategy (Bill H.R. 776) is license renewal of currently operating nuclear power plants which DOE has estimated would save between $800 million and $1 billion in avoided new construction costs - and represent a nationwide benefit of as much as $350 billion - assuming the licenses are renewed for 20 years. The U.S. Atomic Energy Act of 1954 limits the duration of operating licenses of nuclear power plants to a maximum of 40 years but permits their renewal. And, although Title 10, Part 50.51 of Code of Federal Regulations (10CFR50.51) permitted license renewal, it provided no standards or procedures for renewal applications. License renewal requirements were established on January 13, 1992 when NRC's Final Rule (10 CFR Part 54) went into effect. The Final rule established the requirements that an applicant for license renewal must meet, the information that must be submitted to the NRC for review. This involves the performance of an Integrated Plant Assessment (IPA) which is designed to ensure that the effects of aging on important equipment will be adequately managed during the renewal term. The issuance of 10 CFR Part 54 established the regulatory and legal requirements for license renewal. The technical basis for, or viability of, license renewal has been explored by the Electric Power Research Institute (EPRI) since the late 1970s/early 1980s. The NRC as well as industry organizations such as EPRI have studied aging effects for close to two decades. The NRC's research program on plant aging degradation, which began formally in the early 1980s, is a comprehensive effort for the understanding and management of age-related degradation in safety-related systems, structures, and components (SSCs) and

    Cirus, a 40 MWt tank type research reactor located at the Bhabha Atomic Research Centre, is in operation since 1960. In Cirus, heavy water is used as moderator, demineralized light water as primary coolant and natural uranium metal as fuel. The average availability factor had been about 70% till the year 1990 where after it started decreasing due to frequent problems with equipment and components. Systematic aging studies were therefore undertaken to assess the condition of structures, systems and components. Based on these studies, refurbishing requirements were identified and a detailed plan was drawn up for refurbishing. The reactor was shut down in October 1997 for execution of refurbishing jobs. A summary is presented of the results of aging studies and the refurbishing plans. Details of core unloading to facilitate refurbishing and some of the important jobs in the primary coolant system relating to pressure testing of primary coolant pipelines and repairs to identified leaky sections are discussed.

    Unit-l of Rajasthan Atomic Power Station (RAPS-1) is the first nuclear power plant of India with pressurized heavy water reactor. The construction of Unit-l of Rajasthan Atomic Power Station (RAPS-1) was started in the year 1966 in collaboration with Canada. The Unit-1 achieved first criticality on August 1972 and was first synchronized to Grid on November 1972. During initial operation of the Unit, several problems were faced in its various systems and these were addressed by incorporating various engineering changes and procedures. In this unit various major innovative repairs were done like end shield leak repair, OPRD leak repair. Considering the operation of various systems of Unit-1, since year 1971 it was imperative to study ageing degradation mechanisms and mitigating measures were to be taken. Although the ageing management is a continuous process the opportunity of Unit-1 shutdown for upgradations from 30-04-2002 to 08-02-2004 was utilized for inspection and assessment of health of various SSC, which otherwise could not have been done with unit in operational state. This paper contains the following in detail. (1) Ageing management programme, its objectives and scope (2) Methodology of ageing management studies - Replacement and upgradation -Additional inspection programme based on ageing management review - Statistical analysis of ageing degradation occurrence - Estimation of residual life span of cables and relays (3) Criteria for selection of components for ageing management programme (4) Findings of ageing management studies-case studies. The ageing study done for RAPS-1 indicated that appropriate ageing monitoring methods and procedures exist in the station for taking timely mitigating measures. The technological obsoleteness has been overcome by installing new components of latest technology. On overall assessment, the Unit-1 was considered fit for further service. (author)

    Full Text Available Lifestyle nonpharmacological interventions can have a deep effect on cognitive aging. We have reviewed the available literature on the effectiveness of physical activity, intellectual stimulation, and socialization on the incidence of dementia and on the course of dementia itself. Even though physical activity appears to be beneficial in both delaying dementia onset and in the course of the disease, more research is needed before intellectual stimulation and socialization can be considered as treatments and prevention of the disease. Through our paper, we found that all three nonpharmacological treatments provide benefits to cognition and overall well-being in patients with age-related cognitive impairments. These interventions may be beneficial in the management of dementia.

    Paediatric pain management remains a challenge in clinical settings. Parents can contribute to the effective and accurate pain assessment and management of their child. No systematic reviews regarding the parental involvement in their child's post-operative pain management have been published. To determine the best available evidence regarding parental involvement in managing their children's post-operative pain in the hospital setting. The review considered studies that included parents of all ethnic groups with children aged between 6 to 12 years old who were hospitalised and undergone surgery of any kind with post-operative surgical or incision site pain where care was provided in acute hospital settings. The phenomena of interest were the experiences of parents in managing their children's post-operative pain. A three-step search strategy was utilised in each component of this review. Major databases searched included: MEDLINE, CINAHL, Scopus, ScienceDirect, the Cochrane library, PubMed as well as Google Scholar. The search included published studies and papers in English from 1990 to 2009. Each included study was assessed by two independent reviewers using the appropriate appraisal checklists developed by the Joanna Briggs Institute (JBI). Quantitative and qualitative data were extracted from the included papers using standardised data extraction tools from the JBI, Meta-analysis Statistics Assessment and Review Instrument data extraction tool for descriptive/case series and the JBI-Qualitative Assessment and Review Instrument data extraction tool for interpretive and critical research. The five quantitative studies included in this review were not suitable for meta-analysis due to clinical and methodological heterogeneity and therefore the findings are presented in a narrative form. The two qualitative studies were from the same study, therefore meta-synthesis was not possible. Hence the results of the studies were presented in a narrative format. Seven

    A systematic review of the literature was conducted to review and evaluate the evidence supporting a liberalized diet for the management of diabetes mellitus in aged care homes and examine the effect of this on glycaemia, nutritional status and diabetes comorbidity risk factors. A 3 step search of eight databases followed by independent data extraction and quality assessment by two authors was undertaken. Studies which compared therapeutic diets to a liberalized diet or observation studies reviewing the effects of therapeutic diets on glycaemia and nutritional status were included. Of the 546 studies identified, six met the inclusion criteria. Methodological quality of the studies was rated poor and the majority concluded no statistically significant change in diabetes management outcomes with a liberalized diet, but modest increases in glycaemia were observed. Inadequate data was available to determine effects of diet change on nutritional status or diabetes risk factors. Overall studies were in support of a liberalized diet but due to the low quality of the evidence and a lack of significant findings it may not be appropriate to extrapolate these conclusions to inform dietetic practice.

    Since the adoption of the 1997 act of parliament concerning the abolishment of nuclear power in Sweden plant lives are no longer limited until 2010 as they were following the referendum in 1980. The Swedish Nuclear Power Inspectorate (SKI) has therefore in its most recent general regulations from 2004 introduced requirements for plants to develop ageing management programmes which should have been in place by the end of 2005. An ageing management programme for a nuclear power plant can be viewed as a high level coordinated programme consisting of several other programmes including maintenance and inspection programmes, and as such it should be an integrated part of the quality assurance system of the plant. The goals of the programme are to ensure that there is long term management of ageing and avoidance of the unexpected. For the Swedish regulator the safety aspects and not the economic aspects of ageing management are of primary importance. But there are clear advantages to utilities if large surprises which result in unplanned outages can be avoided. (author)

    Deficiencies in the knowledge, skills and attitudes of all healthcare professionals working within the general hospital contribute towards the suboptimal care of older hospitalized patients with confusion. In the U.K., policy dictates that Liaison Old Age Psychiatry teams deliver effective education to general hospital clinical staff. The purpose of this paper is to review the literature concerning the learning needs of healthcare professionals in relation to managing confusion in the older patient in order to inform effective educational approaches for Liaison Old Age Psychiatry teams. A broad range of medical and educational databases were searched. Identified English language studies were selected for further analysis if they had a specific educational focus in the hospital setting and then further subdivided into intervention and naturalistic studies. The impact of intervention studies was evaluated by Kirkpatrick's system. Learning needs, as determined from the naturalistic studies, were mapped to identify themes. 13 intervention studies were identified. Despite a high level of effectiveness for educational interventions, it was unclear what the active components were. A further 23 naturalistic studies were identified; their findings focused on knowledge gaps, diagnostic behaviors and experiences, attitudes and training issues. Few studies specifically researched learning needs or the educational role of liaison teams. Conspicuous by its absence was reference to relevant educational theories. The findings of this review can be incorporated in the planning of local curricula by Liaison Teams in order to design educational strategies. There is a need for further research, especially studies exploring the learning needs of all healthcare professionals.

    In China, the first two NPPs have operated over 15 years (QNPC) and 13 years (Dayabay). Now, most of Chinese NPPs have started their ageing management project. Steam generator (SG) is one of key safety important components for PWR and CANDU, which is selected as the first group of components to develop component ageing management system. QNPC and TQNPC have made some progress in this area. The basic SG ageing management system has been set up, and some application has been under way. To set up SG basic ageing management system, we start with (1) SG ageing mechanism analysis (2) Developing SG ageing management programme (3) Developing SG ageing management information system, SGAMDB (4) Ageing degradation assessment and remained life evaluation SG ageing mechanisms are classified as function degradation and material/structure degradation. The specific tables with unified format are used to analyze the ageing mechanism. The numbering requirements for ageing mechanism are developed to manage them in ageing information system. All ageing mechanisms are graded I and II and III based on its feasibility, impact on safety and operation experience, so that the key mechanisms are managed more strictly. SG ageing management programme (SGAMP), which is fundamental document for ageing management, provides the requirements for working process, what to do and when to do. SGAMP reviewing and improving requirements are as well included. SG ageing management database (SGAMDB) is the first component ageing management database for Chinese NPP, which have been installed and are in operation in QNPC and TQNPC.

Critical representative components As result of the screening resulted a lot of components to be monitored from ageing point of view. But some are redundant components or are similar and work in the same conditions. For this reason where chosen critical representative components. The conclusions on these representative components shall be applied also to the rest of the critical components. 4. Correlation with maintenance categories. As result of the components screening results: Critical components (from the safety and reliability point of view); for these components shall be applied Condition Oriented Preventive Maintenance; Non critical components; for these components shall be applied Corrective Maintenance (they are Run to Failure Components); If during plant operation result that for some critical components it is enough to realize maintenance based on the manufacturer instruction, shall be applied for them Time Oriented Preventive Maintenance (instead of Condition Oriented Preventive Maintenance). Of course this is the first selection. After some times of application at Cernavoda NPP of an ageing Management Program it shall be revised according to the results in operation. (author)

    Ageing of nuclear power plants means evolution of material or equipment properties on one side, and evolution of personnel skill and procedure adequacy on the other side, both of which, after a certain time, may not be compatible with the required safety provisions, or with an economic operation of the plant. Repair or replacement of components, as well as change in service conditions for a better compatibility with component reduced capabilities can be used to mitigate ageing effects. The paper summarises the results of a study conducted in this field with the support of the European Commission. It presents: the synthesis of the work done under international auspices, and in the European context; the comparison of ageing management approaches used in several European countries with international recommendations; the summary of the various potential phenomena and their governing parameters, the methods of in-service ageing identification and possible mitigation methods; illustrative ageing management practices, taking material ageing aspects as examples. Concerning the first topic, the European report identifies 56 OECD and IAEA reports on ageing management issues, 35 being summarised in an appendix to the report. It also identifies numerous European and international studies covering topics of interest to ageing and Plant Life management. ageing management approaches have been considered from the regulatory point of view and from the utilities management point of view. Contributors to the study have identified a general consensus in Europe, with no limited time operating authorisation, the safety being a utility responsibility under continuous surveillance by the regulatory authority. Practical ageing management methods include: periodic safety reviews (PSR), a ten years periodicity being a common practice, completed by continuous ageing management taking into account safety and industrial anticipation needs; the implementation of life-time management programmes

    Chockie, A.; Bjorkelo, K.

    1992-01-01

    For a variety of economic and technical reasons, there has been a growing concern with the aging of complex systems and components and the role that maintenance can play in reducing this degradation. 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 that their maintenance programs have on their ability to address the systems and component aging degradation issues. An effective maintenance program was found to be essential to the management of system and component aging. The four key elements of an effective maintenance program that are important to an aging management program were identified. These are: the selection of critical systems and components; the development of an understanding of aging through the collection and analysis of equipment performance information; the development of appropriate preventive and predictive maintenance tasks to manage equipment and system aging degradation; 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. In examining how the four organizations have structured their maintenance programs to include these key elements provides valuable lessons not only for the nuclear power industry, but also for any industrial organization that is concerned with the management of system and component aging degradation. This document provides detail, of these studies

    The knowledge of how the environment and load of organic material in general and especially polymers and lubricants, is affecting the degradation of important properties, have increased during the last decade. However the restrictions using established additives like some color pigments due to their poisonousness e.g. pigments based at cadmium, lead, mercury etc. have caused problems when replacing additives to polymers. The replacement additives have often been used in new design without going through the required material qualification procedure. There have also been observed that some non-qualified and non-approved materials have been installed in some power plants due to false documentation. There are also a lot of new manufacturers, of materials similar to the previously qualified materials, active at the market. This increases the difficulty to ensure that the required material quality is used. New materials, new additives and new manufacturers makes if more and more difficult to assure that the expected material is present. This causes more strict demands of how the new materials often used in equipment at type-testing and in replacement materials are analyzed and documented. By implementing new steps for chemical, mechanical and electrical analysis and increase the general quality assurance content this issue can be managed. (authors)

    Ageing management has now become a vital area of concern. Ageing management includes determination of degradation factors, taking various steps to determine present conditions of systems, structures and components and taking mitigating steps. It also includes updating, modernization, refurbishment etc. It is important that ageing management starts right from the time of commissioning of the unit and is treated as a continuous process, and a parallel effort to the normal running of the plant. Thus elaborate research and development efforts are required to be instituted. Life extension could have a high benefit to cost ratio. Various steps to ensure safety in ageing management are listed. Selection of critical items, condition monitoring and life estimation of the same and a chronological check sheet from 0 to 60 years, for Indian PHWRs is explained. Areas where future research and development and other efforts need to be directed is listed. The paper concludes emphasizing the need for a systematized approach to ageing management. It recommends intensive research in certain listed areas and suggests standing committees in specialized areas to tap Indian experience in other industries and establishments. A safety guide is also required to be produced to cover all facets of ageing management. (author). 3 appendices

    It is a generally accepted fact that while designing a concrete structure the durability parameters of construction materials should be evaluated as carefully as possible like other properties such as mechanical, physical and chemical properties. No material is inherently durable as result of environmental interaction with microstructure and consequently, the properties of the materials change with time due to weathering action, chemical attack, abrasion or any mode of degradation. The main cause of ageing on structure, water, which is primary for both creation and destruction on many natural materials. In porous materials, water creates different types of physical and chemical process of degradation. The water movement through porous materials are controlled by the permeability of the respective materials. The rate of deterioration is affected by type of concentration of ions present in the water and chemical deposition of materials. Controlling weathering action, chemical attack, abrasion and selecting good quality construction material and methods of construction can increase the service life of the structure. (author)

    A nuclear power plant's maintenance program is the principal vehicle through which age-related degradation is managed. Over the past two years, the NRC [Nuclear Regulatory Commission] has evaluated the maintenance program of every nuclear power plant in the U.S. The reports issued on these in-depth team inspections have been reviewed to ascertain the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear power plant systems, structures, and components. Selected results of this review are presented in this paper, including examples of inspection and monitoring techniques successfully used by utilities to detect degradation due to aging. Attributes of plant maintenance programs where the NRC inspectors felt that improvement was needed to properly address the aging issue are also discussed. 6 refs., 1 tab

    In Germany, the term 'ageing management' comprises several aspects. A demand for a special ageing monitoring programme is not explicitly contained in the regulations. However, from the Atomic Energy Act and its regulations results the operator's obligation to perform extensive measures to maintain the quality of the plant and the operating personnel working in the plant. From this point of view, comprehensive ageing management in German nuclear power plants has taken place right from the start under the generic term of quality assurance. (author)

    2002-01-01

    In Korea plant lifetime management (PLIM) study for Kori Unit 1 has been performed since 1993. Meanwhile, periodic safety review (PSR) for all operating nuclear power plants (NPPs) has been started with Kori Unit 1 since 2000 per IAEA recommendation. The evaluation period is 10 years, and safety (evaluation) factors are 11 per IAEA guidelines as represented in table 1. The relationship between PSR factors and PLIM is also represented. Among these factors evaluation of 'management of aging' is one of the most important and difficult factor. This factor is related to 'actual condition of the NPP', 'use of experience from other nuclear NPPs and of research findings', and 'management of aging'. The object of 'management of aging' is to obtain plant safety through identifying actual condition of system, structure and components (SSCs) and evaluating aging phenomena and residual life of SSCs using operating experience and research findings. The paper describes the scope and procedure of valuation of 'management of aging', such as, screening criteria of SSCs, Code and Standards, evaluation of SSCs and safety issues as represented. Evaluating SSCs are determined using final safety analysis report (FSAR) and power unit maintenance system for Nuclear Ver. III (PUMAS/N-III). The screening criteria of SSCs are safety-related items (quality class Q), safety-impact items (quality class T), backfitting rule items (fire protection (10CFR50.48), environmental qualification (10CFR50.49), pressurized thermal shock (10CFR50.61), anticipated transient without scram (10CFR50.62), and station blackout (10CFR50.63)) and regulating authority requiring items[1∼3]. The purpose of review of Code and Standards is identifying actual condition of the NPP and evaluating aging management using effective Code and Standards corresponding to reactor facilities. Code and Standards is composed of regulating laws, FSAR items, administrative actions, regulating actions, agreement items, and other

The Recent views of aging indicating that aging is extremely a complex multifactorial process despite of earlier views about definite cause aging like gene or decline of a key factor(1. This brief review tries to inspect aging at the molecular, cellular, and systemic levels; and consider interaction between genetic and environmental factors. Evolutionary theories argue that aging results from a decline in the force of natural selection. On the other hand, molecular theories emphasis on the genetically regulation of aging and argue that aging results from changing in genes. There are cellular theories that telomere theory is most famous. Stress induced aging is in this group too. free radical theory is next known way for cellular damages. Finally, we see systemic theories that contain two main groups, neuroendocrine and immunologic theories.

    Understanding degradation phenomena and managing the detrimental effects of aging are important aspects of commercial nuclear power plant operations. Potential for materials degradation should be considered early in the design and development stages; during manufacturing, construction, and installation; and during all aspects of plant operation and maintenance. This would lead to increased reliability during plant operations, and would reduce the need for mitigating actions and unplanned maintenance. Thus, it is necessary to instill a culture at the technical, administrative, and management levels that continually asks, 'What happens with time?' The answer to this question is central to the continuous safe and economical operation of nuclear power plants. Based on the past 25 years of aging-related research at the U.S. Nuclear Regulatory Commission (NRC), the authors present an overview of the key elements of understanding and managing aging, and how they should be integrated for safe and economical power plant operation. The focus of this paper is hardware-oriented engineering and aging of materials. The paper discusses previous and ongoing NRC research studies on non-destructive examination and materials degradation that can be applied for proactive management of materials degradation and aging during plant operations.

    1989-01-01

    Over the past 5 years, the Nuclear Plant Aging Research program (NPAR) has been devoted to developing technical understanding of the time dependent processes that, through deterioration of components, systems, or structures (C/S/S), can reduce safety margins in nuclear power plants. A major and necessary element of the program involves the application of this basic knowledge in defining functional approaches to managing aging by anticipating and mitigating important deterioration processes. Fundamental understanding and characterization of aging processes are being accomplished through NPAR-sponsored research projects, review and analysis of aging related information, integration of NPAR results with those from industry and other aging studies, and interfacing of all of these with the existing body of codes, standards and regulatory instruments that convey aging-related guidance to NPP licensees. Products of these efforts are applied to structuring and providing aging-related technical recommendations in forms that are useful in: (1) developing and implementing good aging management practices, (2) developing regulatory guidance and requirements for understanding and managing aging during normal plant operations and in support of license renewal, and (3) planning and implementing other regulatory actions and initiatives in which aging-related concerns have a bearing on scope or priority

    2004-01-01

    Bechtel is currently completing an aging study on a concrete containment structure. The target plant is a two-unit PWR plant with a generating capacity of about 850 MWe from each unit. Both units are less than 20 years old. The total electrical energy output from this plant site accounts for more than 50% of the utility's baseload operation. Although no utility in the United States has made a decision to submit a license renewal application, some have begun to investigate the feasibility of developing an life cycle management (LCM) program for a strategy to operate their plants efficiently, to investigate the financial benefit and safety implications of license renewal to operate their nuclear power plants beyond their current licensed periods, and to prepare a program plan for plant decommissioning. The LCM program includes economic, environmental, regulatory and technical aspects of continuing plant operations beyond the current license period. The Electric Power Research Institute (EPRI) has been supportive to assist utilities and owners groups in their research and development efforts to develop the technical requirements and the issues associated with important to license renewal structures. The focus of this paper is on the technical issues related to the evaluation of the material condition of the containment structure with respect to aging and the effective management of that aging.

    1989-01-01

    Significant safety improvements can be achieved in diesel-generator management related to aging, testing, and other important regulatory concerns. This paper reports on the progress of aging research related to nuclear service diesel generators, which developed data and information supporting the recommended safety improvements. The key to diesel-generator safety improvements is the development of a new balanced approach where testing, inspections, monitoring and trending, training, and maintenance all have appropriate importance. Safety improvement is projected in a management program that concurrently achieves three goals: first, the reduction of the fast-start stressor by regulatory and utility actions; second, the establishment of more appropriate testing and trending procedures; third, the adoption and use of reliability-centered maintenance activities. This paper describes the recommended safety improvements and the positive role of utility management in the process and outlines a new recommended regulatory approach. Diesel generator aging and wear is the subject of research sponsored by the Nuclear Plant Aging Research (NPAR) Program under the US Nuclear Regulatory Commission (NRC). Office of Nuclear Regulatory Research. The research was conducted by Pacific Northwest Laboratory (PNL), which is operated for the US Department of Energy by Battelle Memorial Institute. 4 refs., 1 fig., 1 tab

    2009-01-01

    The containment system in a Nuclear Power Plant (NPP) provides the final physical barrier against release of radioactive materials to the external environment. Even though there are different physical configurations to meet this fundamental safety function in various reactor types, a common feature is the use of a thick-walled concrete structure as part of the containment system commonly referred to as 'Concrete Containment Building'. In order for the concrete containment buildings to continue to provide the required safety function, it has to maintain its structural integrity. As well, its leak rates under test pressures must be maintained below acceptable limits. As some of the containment buildings of the CANDU nuclear power plants are approaching their fourth decade of successful operation, questions regarding the impact of ageing on their ultimate useful service life emerge. Ageing Management has become the tool for addressing those questions. In this paper, the ageing and ageing management of the CANDU concrete containments are discussed, including the specific programs being implemented to monitor and trend the ageing conditions. Specifically, the usefulness of the embedded strain gauges as a tool for the assessment of the condition of the containment concrete structure is discussed. Some of the operational and test data accumulated over the last 30 years have been evaluated and trended to provide some results and conclusions regarding the satisfactory long-term behaviour of the concrete containment buildings.

    HANARO is a 30 MW open pool type research reactor which has been operated for 16 years since its initial criticality in February 1995. It has been used for nuclear material testing, radioisotope production, neutron transmutation doping, nuclear activation analysis, and neutron scattering experiments. Recently, new facilities such as FTL (Fuel Transfer Loop) and CNS (Cold Neutron Source) were installed in the reactor. HANARO was originally designed to operate for at least 20 years under full power operating condition, but the actual life time is expected to be much more than the design lifetime by supporting with a safety reassessment based on realistic data and maintenance activities for an ageing management. The conducted inspections, maintenance activities, and the future plan of the ageing management for HANARO are presented in this paper. (author)

    2006-01-01

    The aspects of plant ageing management (AM) gained increasing attention over the last ten years. Numerous technical studies have been performed to study the impact of ageing mechanisms on the safe and reliable operation of nuclear power plants. National research activities have been initiated or are in progress to provide the technical basis for decision making processes. The long-term operation of nuclear power plants is influenced by economic considerations, the socio-economic environment including public acceptance, developments in research and the regulatory framework, the availability of technical infrastructure to maintain and service the systems, structures and components as well as qualified personnel. Besides national activities there are a number of international activities in particular under the umbrella of the IAEA, the OECD and the EU. The paper will provide the summary on Nuclear Plant Life Management (PLIM) (or Ageing Management Program (AMP)) and Plant Life Extension (PLEX) development in USA and European countries. Also, insights from such effort currently performing in Slovenia will be discussed.(author)

    2012-01-01

    The majority of System, Structure and Components (SSC) in a nuclear power plants are designed to experience a service life, which is far above the intended design life. In most cases, only a small percentage of SSCs are subject to significant aging effects, which may affect the integrity or the function of the component. The process of aging management (AM) has the objective to monitor and control degradation effects which may compromise safety functions of the plant. And furthermore, to ensure, that testing and maintenance programs sufficiently provide preventive measures to control degradation effects. Safety-related aspects and the targeted high availability of the power plant as well as the requirements stipulated by German regulatory authorities prompted the operator of NPP ISAR to introduce an aging surveillance program. The NPP Isar as well as the German NPPs has to be following in the scope of aging management the KTA 1403 guideline. The NPP Isar surveillance program based on the KTA 1403 guideline covers the following aspects: - Scoping and screening of safety relevant Systems, Structures and Components (SSC); - Identification of possible degradation mechanisms for safety relevant SSC; - Ensure, that testing and maintenance programs sufficiently provide preventive measures to control degradation effects; - Transferability check of industry experience (internal and external events); - Annual preparation of an AM status report.

  18. Aging with HIV: a practical review

    Directory of Open Access Journals (Sweden)

    Sandra Wagner Cardoso

    Full Text Available The worldwide elderly population is expected to grow by an additional 694 million people by 2025. By that time, there will be approximately two billion elderly people in the world, most of whom (80% will be living in developing countries. Based on recent estimates, this population will number over 40 million in 2030 in Brazil and a consequent increase in governmental spending for this population can be expected. Since highly active antiretroviral therapy became available in the mid-1990s, the life expectancy of people living with HIV has increased significantly. Approximately 12 million life years were added to the world between 1996 and 2008 as a consequence of wider access to highly active antiretroviral therapy. In Brazil, the incidence of AIDS among the population aged >50 years doubled between 1996 and 2006. The development of antiretroviral therapy has allowed individuals diagnosed at a younger age to live longer, which partially explains the aging tendency associated with the HIV/AIDS epidemic. It is estimated that by 2015, subjects aged >50 years will represent 50% of the people living with HIV undergoing clinical treatment. This scenario presents some challenges, including the fact that the diagnosis of HIV tends to be delayed in older patients compared to younger patients because the symptoms of HIV can be confused with those of other common diseases among the elderly and also because healthcare professionals do not consider this population to be at high risk for HIV infection. In regard to the individuals diagnosed with HIV, a further challenge is presented by the morbidity normally associated with aging. Finally, the elderly also exhibit higher susceptibility to the toxic effects and pharmacological interactions of medications. The present article reviews the literature regarding the profile of HIV infection among individuals aged >50 years focusing on practical features related to the clinical approach and long-term follow-up of

    He Jie; Xu Xianhong

    2010-01-01

    The problem of nuclear reactor ageing is a topic of increasing importance in nuclear safety recent years. Ageing management is usually implemented for reactors maintenance. In the practice, a large number of data and records need to be processed. However, there are few professional software applications that aid reactor ageing management, especially for research reactors. This paper introduces the design of a new web-based management information system (MIS), named the Shielding Experimental Reactor Ageing Management Information System (SERAMIS).

    The problem of nuclear reactor ageing is a topic of increasing importance in nuclear safety recent years. Ageing management is usually implemented for reactors maintenance. In the practice, a large number of data and records need to be processed. However, there are few professional software applications that aid reactor ageing management, especially for research reactors. This paper introduces the design of a new web-based management information system (MIS), named the Shielding Experimental Reactor Ageing Management Information System (SERAMIS). It is an auxiliary means that helps to collect data, keep records, and retrieve information for a research reactor ageing management. The Java2 Enterprise Edition (J2EE) and network database techniques, such as three-tiered model, Model-View-Controller architecture, transaction-oriented operations, and JavaScript techniques, are used in the development of this system. The functionalities of the application cover periodic safety review (PSR), regulatory references, data inspection, and SSCs classification according to ageing management methodology. Data and examples are presented to demonstrate the functionalities. For future work, techniques of data mining will be employed to support decision-making.

    Effective ageing management is an important element for ensuring the safety of nuclear power plant. The IAEA Ageing Management Assessment Team (AMAT) programme provides advice and assistance to utilities or individual NPPs to strengthen and enhance the effectiveness of ageing management programs (AMPs). Such AMPs are required by an increasing number of safety utilities and implemented by an increasing number of utilities, often as a part of NPP life or life cycle management programs that involve the integration of ageing management and economic planning. The guidelines in this report are primarily intended for IAEA-led AMAT team members as a basic structure and common reference for peer reviews of AMPs

    Cost-effective power generation is becoming more important as the prices charged by power producers in the energy market continue to fall. To ease the cost situation there is a growing demand for innovative maintenance management methods which allow power plants to be economically operated over their entire lifetime. The purpose of a systematic ageing and plant life management program is to allow the lifetime of plant components to be planned, and to indicate when a component has reached the end of its effective lifetime before it fails. Another important function of such programs is to increase the availability of power plants as they age, and to enable implementation of a targeted maintenance strategy in terms of its economic and technical effect. Implementation of such programs requires the existence of detailed information concerning the status of the components as well as their operating conditions. Based on this information, an understanding of how the relevant ageing and degradation mechanisms work enables a prediction to be made concerning component lifetime. Advanced software programs provide such predictions at reasonable cost across all systems. (author)

    Importance Human immunodeficiency virus (HIV)-positive patients treated with antiretroviral therapy now have increased life expectancy and develop chronic illnesses that are often seen in older HIV-negative patients. Objective To address emerging issues related to aging with HIV. Screening older adults for HIV, diagnosis of concomitant diseases, management of multiple comorbid medical illnesses, social isolation, polypharmacy, and factors associated with end-of-life care are reviewed. Evidence Acquisition Published guidelines and consensus statements were reviewed. PubMed and PsycINFO were searched between January 2000 and February 2013. Articles not appearing in the search that were referenced by reviewed articles were also evaluated. Findings The population of older HIV-positive patients is rapidly expanding. It is estimated that by 2015 one-half of the individuals in the United States with HIV will be older than age 50. Older HIV-infected patients are prone to having similar chronic diseases as their HIV-negative counterparts, as well as illnesses associated with co-infections. Medical treatments associated with these conditions, when added to an antiretroviral regimen, increase risk for polypharmacy. Care of aging HIV-infected patients involves a need to balance a number of concurrent comorbid medical conditions. Conclusions and Relevance HIV is no longer a fatal disease. Management of multiple comorbid diseases is a common feature associated with longer life expectancy in HIV-positive patients. There is a need to better understand how to optimize the care of these patients. PMID:23549585

    Accident prevention is the first safety priority of both designers and operators. It is achieved through the use of reliable structures, components, systems and procedures in a plant operated by personnel who are committed to a strong safety culture. For future nuclear power plants, consideration of multiple failures and severe accidents will be achieved in a more systematic and complete way from the design stage. Defence in depth (DID) consists of a hierarchical deployment of different levels of equipment and procedures in order to maintain the effectiveness of physical barriers placed between radioactive materials and workers, the public or the environment, in normal operation, anticipated operational occurrences and, for some barriers, in accidents at the plant. The primary way of preventing accidents is to achieve a high quality in design, construction and operation of the plant, and thereby to ensure that deviations from normal operation are infrequent. The best way to meet these premises of effectiveness of the barriers and the Systems, Structures and Components (SSCs) is to develop an ageing management programme to prevent potential failures and accidents. In this work we will refer to the ageing management programme for Atucha I and Atucha II power plants and to the Atucha I spent fuel storage. (author)

    Participatory medicine and the availability of commercial technologies have given patients more options to view and track their health information and to communicate with their providers. This shift in the clinical process may be of particular importance in mental healthcare where rapport plays a significant role in the therapeutic process. In this review, we examined literature related to the impact of technology on the clinical workflow and patient-provider rapport in the mental health field between January 2014 and June 2017. Thirty three relevant articles, of 226 identified articles, were summarized. The use of technology clinically has evolved from making care more accessible and efficient to leveraging technology to improve care, communication, and patient-provider rapport. Evidence exists demonstrating that information and communication technologies may improve care by better connecting patients and providers and by improving patient-provider rapport, although further research is needed.

  13. Ageing vision and falls: a review.

    2018-04-23

    Falls are the leading cause of accidental injury and death among older adults. One of three adults over the age of 65 years falls annually. As the size of elderly population increases, falls become a major concern for public health and there is a pressing need to understand the causes of falls thoroughly. While it is well documented that visual functions such as visual acuity, contrast sensitivity, and stereo acuity are correlated with fall risks, little attention has been paid to the relationship between falls and the ability of the visual system to perceive motion in the environment. The omission of visual motion perception in the literature is a critical gap because it is an essential function in maintaining balance. In the present article, we first review existing studies regarding visual risk factors for falls and the effect of ageing vision on falls. We then present a group of phenomena such as vection and sensory reweighting that provide information on how visual motion signals are used to maintain balance. We suggest that the current list of visual risk factors for falls should be elaborated by taking into account the relationship between visual motion perception and balance control.

    The usage of mobile phones and the internet by young people has increased rapidly in the past decade, approaching saturation by middle childhood in developed countries. Besides many benefits, online content, contact or conduct can be associated with risk of harm; most research has examined whether aggressive or sexual harms result from this. We examine the nature and prevalence of such risks, and evaluate the evidence regarding the factors that increase or protect against harm resulting from such risks, so as to inform the academic and practitioner knowledge base. We also identify the conceptual and methodological challenges encountered in this relatively new body of research, and highlight the pressing research gaps. Given the pace of change in the market for communication technologies, we review research published since 2008. Following a thorough bibliographic search of literature from the key disciplines (psychology, sociology, education, media studies and computing sciences), the review concentrates on recent, high quality empirical studies, contextualizing these within an overview of the field. Risks of cyberbullying, contact with strangers, sexual messaging ('sexting') and pornography generally affect fewer than one in five adolescents. Prevalence estimates vary according to definition and measurement, but do not appear to be rising substantially with increasing access to mobile and online technologies, possibly because these technologies pose no additional risk to offline behaviour, or because any risks are offset by a commensurate growth in safety awareness and initiatives. While not all online risks result in self-reported harm, a range of adverse emotional and psychosocial consequences is revealed by longitudinal studies. Useful for identifying which children are more vulnerable than others, evidence reveals several risk factors: personality factors (sensation-seeking, low self-esteem, psychological difficulties), social factors (lack of parental support

    Cheese whey is simultaneously an effluent with nutritional value and a strong organic and saline content. Cheese whey management has been focused in the development of biological treatments without valorization; biological treatments with valorization; physicochemical treatments and direct land application. In the first case, aerobic digestion is reported. In the second case, six main processes are described in the literature: anaerobic digestion, lactose hydrolysis, fermentation to ethanol, hydrogen or lactic acid and direct production of electricity through microbial fuel cells. Thermal and isoelectric precipitation, thermocalcic precipitation, coagulation/flocculation, acid precipitation, electrochemical and membrane technologies have been considered as possible and attractive physicochemical processes to valorize or treat cheese whey. The direct land application is a common and longstanding practice, although some precautions are required. In this review, these different solutions are analyzed. The paper describes the main reactors used, the influence of the main operating variables, the microorganisms or reagents employed and the characterizations of the final effluent principally in terms of chemical oxygen demand. In addition, the experimental conditions and the main results reported in the literature are compiled. Finally, the comparison between the different treatment alternatives and the presentation of potential treatment lines are postulated. Copyright © 2012 Elsevier Ltd. All rights reserved.

    We investigate the relationship between age and the five dimensions of time perspective measured by the Zimbardo Time Perspective Inventory (ZTPI) (past negative, past positive, present hedonistic, present fatalistic, and future). Time perspective is related to well-being, decision-making, level of development, and many other psychological issues. Hence, the existence of a systematic relationship between time perspective and age should be considered in all studies for which time is a relevant variable. However, no specific research about this has been conducted. We collected 407 papers that referenced the ZTPI between 2001 and 2015. From those, 72 studies met our inclusion criteria. They included 29,815 participants from 19 countries whose age spans most phases of adulthood (from 13.5 to 75.5 years, mean 28.7). We analyzed these studies adapting meta-analytical techniques. We found that present hedonistic and past negative dimensions are negatively related to aging with partial eta squared effect sizes of roughly 0.15. Our results have implications for the design of studies related to time as our findings highlight the importance of taking into account the differences associated with age.

  5. Belgium: National approach to ageing management

    International Nuclear Information System (INIS)

    2014-01-01

    In Belgium, the licenses for operation of the nuclear power plants granted by Royal Decree do not specify a fixed lifetime. The oldest plants, Doel 1&2 and Tihange 1, have been operational since 1975. The 2003 law regarding the exit from nuclear power limits the operation of nuclear power plants to 40 years. However, in October 2009, the Belgian government declared that they intended to make it legally possible for Doel 1&2 and Tihange 1 to operate until 2025, which would mean a total lifetime of 50 years (this statement was confirmed by the Belgian government in June 2012, only for the Tihange 1 plant). The Belgian Federal Agency for Nuclear Control (FANC) published in 2009 a strategic note regarding the requirements of long-term operation for Doel 1&2 and Tihange 1. Electrabel GDF SUEZ started its LTO programme in order to respond to these requirements. The LTO programme consisted of the following areas of concern, identified in the FANC strategic note: − Preconditions for long-term operation considering the IAEA expectations; − Ageing management; − Design re-evaluation; − Knowledge, competence and behaviour management. The note also stated that the long-term operation of the plants should be evaluated within the framework of the fourth ten-yearly PSR, based upon IAEA NS-G-2.10. As such a license renewal was not required for LTO and the LTO approval will be integrated in the approval process of the 4th PSR. In its strategic note, the Belgian Federal Agency for Nuclear Control explicitly states that the AMP has to be in conformity with the USNRC 10CFR54 and IAEA SRS 57

    The older population is becoming more important to our society everyday. These individuals are being studied for their past, present, and potential impact on markets and marketing. Evaluated as a user of products or services in the marketplace or an employee or volunteer within the marketing system, this segment is gaining a visibility and importance. An interview was conducted with five Nutrition Project Directors to obtain an overview of Federally Funded Nutrition Programs for the Elderly. The areas which were highlighted were service delivery, site activities, management styles, barriers to service, clientele composition, food planning and preparation, staffing, USDA funding, coordination, marketing, transportation, and volunteerism. The Second Quarter Service Provider Output Reports for 1991, which are compiled by the Nutrition Projects and submitted to the Area Agency on Aging, were utilized to obtain client profile information (Reports, 1991). The analysis sought to compare the programs offered in the five counties on a number of factors which could be quantified. It was hoped that by looking at the numerical ratios, and depicting them graphically, any trends or unique characteristics of the programs could be identified. In that the percentage of Florida's present elder population (17%) far exceeds the national average (12%) these findings could be utilized by nutrition programs outside of Florida to plan for future funds. Analysis of quantitative information on the five programs yielded information on cost comparisons and on services.

    NUR is a 1 MW, open pool reactor moderated and cooled by light water. It was commissioned in 1989. NUR is used for education and training in Nuclear Engineering and related topics for COMENA and National Scientific Community. It is also used to perform R and D works and services at national and regional levels. In this presentation, we describe the methodology and the main development activities related to the ageing management at NUR reactor. These activities include inspection actions and development actions to introduce modifications, to solve obsolescence issues in view to implement the required preventive and curative maintenance programs and to improve the performances of the installation. These actions involved mainly the Operation Assistance System of the Reactor (OAS), the secondary cooling loop, the cooling tower. A new OAS using a new technology and having more possibilities than the older one was introduced in the control system of the reactor. The OAS hardware structure, software structure and the main functions performed are presented. The second loop is entirely refurbished. Two new cooling towers are installed and connected to the main heat exchanger with new piping and valves. The architecture of this new installation is described and the performance assessed. Other actions which involve auxiliary systems like emergency electrical system, air pneumatic system and automatic fire extinguishing are presented.

    The condition of a physical system such as a radioactive materials transportation package can change as it ages. The degree to which aging effects are identified, prevented or mitigated will depend on the types of inspections and maintenance performed on the critical components of the system. Routine inspections and maintenance may not address degradation mechanisms that are difficult to observe and can act over long periods of time. Aging management is a systematic effort to ensure that the system performs as designed over its entire service life and that degradation mechanisms do not prematurely end the service life. The Nuclear Waste Management Division (NWMD) of Ontario Power Generation (OPG) has developed an Aging Management Procedure and began performing aging management assessments on its Type B(U) packages. This paper discusses the Procedure and briefly describes the aging management assessment performed on the Roadrunner Transportation Package to demonstrate a practical application of the aging management process

    Systematic reviews comprehensively summarize evidence about the effectiveness of conservation interventions. We investigated the contribution to management decisions made by this growing body of literature. We identified 43 systematic reviews of conservation evidence, 23 of which drew some concrete conclusions relevant to management. Most reviews addressed conservation interventions relevant to policy decisions; only 35% considered practical on-the-ground management interventions. The majority of reviews covered only a small fraction of the geographic and taxonomic breadth they aimed to address (median = 13% of relevant countries and 16% of relevant taxa). The likelihood that reviews contained at least some implications for management tended to increase as geographic coverage increased and to decline as taxonomic breadth increased. These results suggest the breadth of a systematic review requires careful consideration. Reviews identified a mean of 312 relevant primary studies but excluded 88% of these because of deficiencies in design or a failure to meet other inclusion criteria. Reviews summarized on average 284 data sets and 112 years of research activity, yet the likelihood that their results had at least some implications for management did not increase as the amount of primary research summarized increased. In some cases, conclusions were elusive despite the inclusion of hundreds of data sets and years of cumulative research activity. Systematic reviews are an important part of the conservation decision making tool kit, although we believe the benefits of systematic reviews could be significantly enhanced by increasing the number of reviews focused on questions of direct relevance to on-the-ground managers; defining a more focused geographic and taxonomic breadth that better reflects available data; including a broader range of evidence types; and appraising the cost-effectiveness of interventions. © 2013 The Authors.

    Colon cancer is more common in the elderly than in younger and middle-aged people. Cancer clinical trials focus more on younger patients and the management of elderly patients with advanced disease is still unclear. We studied all patients presenting with colon adenocarcinoma metastasis to liver at a community teaching hospital from Dec 2000 through Dec 2007 by a retrospective review of Tumor Registry data and patient chart review with focus on age, clinical management, decision making, and survival. Sixty-seven patients with a median age of 69 and a male to female ratio of 31:36 were identified. The patients with obstructive symptoms and Eastern Cooperative Oncology Group performance status on presentation though varied little by age, smaller proportion of elderly patients underwent resection of the primary bowel tumor in the presence of liver metastases with ten of 16 (63%) aged 80 or greater being managed without surgery. The percentage of patient's preference to physician's preference for patients not undergoing the primary bowel resection increased for older age group. Median survival decreased significantly with age (p management, decision-making autonomy, and survival are apparent in this study, and there was an increasing trend of patient's involvement in decision making as the age increases and, thus, affecting the age-related clinical management.

    Review of technical literature and field experience has identified stress corrosion cracking as one of the major degradation mechanisms for the major light water reactor components. Three of the stress corrosion cracking mechanisms of current concern are (a) primary water stress corrosion cracking (PWSCC) in pressurized water reactors, and (b) intergranular stress corrosion cracking (IGSCC) and (c) irradiation-assisted stress corrosion cracking (IASCC) in boiling water reactors. Effective aging management of stress corrosion cracking mechanisms includes evaluation of interactions between design, materials, stressors, and environment; identification and ranking of susceptible sites; reliable inspection of any damage; assessment of damage rate; mitigation of damage; and repair and replacement using corrosion-resistant materials. Management of PWSCC includes use of lower operating temperatures, reduction in residual tensile stresses, development of reliable inspection techniques, and use of Alloy 690 as replacement material. Management of IGSCC of nozzle and attachment welds includes use of Alloy 82 as weld material, and potential use of hydrogen water chemistry. Management of IASCC also includes potential use of hydrogen water chemistry

    Ageing is time dependent degradation of hardware and measured by percentage deviation of performance parameters with reference to their respective reference values. Ageing is influenced by environmental and operating stresses; lower the magnitude of stresses, lower the rate of degradation and vice versa. This paper describes test results of thermal ageing, radiation ageing and performance during loss of coolant accident (LOCA) environment (steam bound condition at 120 degC) on various types of electrical cables, elastomers and electronic process instruments.

    Since its first criticality in 1982, PUSPATI TRIGA Reactor (RTP) has been operated for more than 30 years. As RTP become older, ageing problems have been seen to be the prominent issues. In addressing the ageing issues, an Ageing Management (AgeM) database for managing related ageing matters was systematically developed. This paper presents the development of AgeM database taking into account all RTP major Systems, Structures and Components (SSCs) and ageing mechanism of these SSCs through the system surveillance program.

  1. Guideline for ageing management in nuclear power plants

    During operation of nuclear power plants, the quality of systems, structures and components may change as a result of ageing (conceptional ageing, technological ageing or physical ageing), which will affect the system quality. Ageing management is necessary to ensure safety and availability throughout the life of the systems. This necessitates a systematic, integrative and knowledge-based approach. Systems, structures and components are grouped according to their relevance for meeting the set goals. Ageing mangement should be process-oriented and should be integrated in the organisational procedure in cooperation with the safety manager. The procedure should follow the PDCA principle (plan - do - check - act). The data, documents, knowledge and evaluations required for ageing management are part of the knowledge base of the nuclear power station and are updated regularly. The efficiency of ageing management must be reassessed at regular intervals. (orig.)

  2. Plant maintenance and aging management: Are they the same?

    Lofaro, R.J.

    1995-01-01

    As part of the NRC's Nuclear Plant Aging Research Program, a number of aging studies were performed on safety-related systems and components which found that, even with current maintenance and monitoring practices in place, a large number of the reported failures are related to aging. This suggests that current practices are not sufficient to completely manage aging degradation, and other factors need to be considered. This paper examines the aging management process and the degree to which maintenance plays a part in it. Component failures and degradation mechanisms identified in aging studies of several different safety systems are summarized and evaluated, then con-elated with the components most frequently failed. This information, along with an analysis of failure causes, is then used to determine the extent to which aging is managed by current maintenance practices. Conclusions and recommendations for proper aging management arc also presented

    As for the whole human body, the kidney undergoes age-related changes which translate in an inexorable and progressive decline in renal function. Renal aging is a multifactorial process where gender, race and genetic background and several key-mediators such as chronic inflammation, oxidative stress, the renin-angiotensin-aldosterone (RAAS) system, impairment in kidney repair capacities and background cardiovascular disease play a significant role. Features of the aging kidney include macroscopic and microscopic changes and important functional adaptations, none of which is pathognomonic of aging. The assessment of renal function in the framework of aging is problematic and the question whether renal aging should be considered as a physiological or pathological process remains a much debated issue. Although promising dietary and pharmacological approaches have been tested to retard aging processes or renal function decline in the elderly, proper lifestyle modifications, as those applicable to the general population, currently represent the most plausible approach to maintain kidney health.

    Aging management is part of the safety management system in NPP Neckarwestheim, Germany. The central goal of aging management is to increase knowledge about aging mechanisms acting on systems, structures and components (SSC), steadily. Comprehensive knowledge is a pre-requisite to guard against aging related systematic failures. To increase knowledge it is necessary to gather and evaluate data of different departments, systematically. While a nuclear power plant is in service numerous events may occur which are related to aging and may have an influence on the quality of SSC. Relevant events may be malfunction, maintenance results, operational experience, results of surveillance or events in other utilities. It is important to evaluate these events concerning the aspect of aging, regularly, and to decide which measures are required to prevent similar unexpected events in the future. In some cases the new experience has to be assigned to comparable SSC. These evaluations and the necessary measures as well as the tracking of their effectiveness are performed by an aging management team that meets every 3 months. The resulting knowledge data base (aging management data base) supports the application of the PDCA cycle and provides an overview and fast access to all quality documents related to each SSC including surveillance measures and results. It simplifies the generation of annual status reports which demonstrate the efficiency of aging management. Finally, the procedure can be extended to SSC which are important for the availability of the plant and thus take a step forward from aging management to plant life management.

    Full text: Cable polymer aging and condition monitoring is being studied in detail under the Nuclear Energy Plant Optimization Program (NEPO) that is co-sponsored by the U.S. Department of Energy and EPRI. Significant advances in modeling of polymer aging and condition monitoring have occurred and continue to be developed. The activities include: Analysis of the linearity of the Arrhenius model to room temperature; Development of a wear-out technique for determining remaining life of cable polymers; Determination of the aging fragility point for composite EPR/CSPE insulation with respect to LOCA function; Development of visual/tactile training aids for cable assessment; Development of a totally new nuclear magnetic resonance condition monitoring technique; Assessment of existing techniques with regard to repeatability, accuracy and ease of use. Through use of highly precise oxygen consumption experiments, the linearity of the Arrhenius model is being evaluated. In these experiments, polymer is placed in vials with a known amount of oxygen and aged at much lower temperatures than is possible with standard accelerated aging techniques. aging results are possible at room temperature. The technique is being applied to commonly used insulation and jacket polymers. The wear-out technique allows highly non-linear aging behavior to be made linear. The wearout point of a polymer is determined through high-rate aging and use of a condition monitoring technique to establish the end point. Then, micro-samples of cable that have been naturally aged are subjected to high rate aging to the same end point. The ratio of the remaining high rate aging period to the total high rate aging time provides a linear indication of the remaining service time. Initial screening of nuclear plant cable systems can use visual/tactile techniques to identify cable that has aged significantly. Training aids have been developed by developing sets of specimens with accelerated aging ranging from none

    This Safety Guide was developed under the IAEA programme for safety standards for research reactors, which covers all the important areas of research reactor safety. It supplements and elaborates upon the safety requirements for ageing management of research reactors that are established in paras 6.68-6.70 and 7.109 of the IAEA Safety Requirements publication, Safety of Research Reactors. The safety of a research reactor requires that provisions be made in its design to facilitate ageing management. Throughout the lifetime of a research reactor, including its decommissioning, ageing management of its structures, systems and components (SSCs) important to safety is required, to ensure continued adequacy of the safety level, reliable operation of the reactor, and compliance with the operational limits and conditions. Managing the safety aspects of research reactor ageing requires implementation of an effective programme for the monitoring, prediction, and timely detection and mitigation of degradation of SSCs important to safety, and for maintaining their integrity and functional capability throughout their service lives. Ageing management is defined as engineering, operation, and maintenance strategy and actions to control within acceptable limits the ageing degradation of SSCs. Ageing management includes activities such as repair, refurbishment and replacement of SSCs, which are similar to other activities carried out at a research reactor in maintenance and testing or when a modification project takes place. However, it is important to recognize that effective management of ageing requires the use of a methodology that will detect and evaluate ageing degradation as a consequence of the service conditions, and involves the application of countermeasures for prevention and mitigation of ageing degradation. The objective of this Safety Guide is to provide recommendations on managing ageing of SSCs important to safety at research reactors on the basis of international

    The aim of this study is to examine the issues and the progress being made in leadership and management with relevance for the residential aged care workforce. A systematic review was conducted using scientific journal databases, hand searching of specialist journals, Google, snowballing and suggestions from experts. After a seven-tiered culling process, we conducted a detailed review of 153 papers relevant to leadership and management development in aged care. Strong, effective leadership and management promotes staff job satisfaction and retention, high care quality and the well-being of care recipients, and reduces associated costs. Good leadership and effective management also play a key role in bringing about a successful change to a positive workplace culture through innovative programs and research projects. Organisational investment in improving leadership and management skills and capabilities can only improve outcomes for staff stability and productivity, care quality and budgets, and better prepare the aged care sector.

    Although the nuclear plant was designed for the purpose of the 30-year life the early stages of construction, it also already has the plant abolished by passing in 30 years. There is a plant under operation and a plant that is employed variously, extends the original life and continues operation now, and the plant that is going to be abolished politically is before a life. By using a nuclear plant for a long period of time, damage. by the influence of irradiation, wear of slipping, corrosion, etc. appears. When this degradation is left, the serious accident is caused. In this lecture, refer to Assessment and management of ageing of major nuclear power plant components important to safety, Oct. 1999 of IAEA. A point of view from guide is introduced about management of the mechanism in the secular degradation mode expected by operating for a long period of time, the influence of secular degradation, and influence, monitoring technology, periodical safe evaluation, and a periodic inspection. And raises and explains the correspondence situation of secular degradation, and the example of evaluation of PSR and ISI equipment. The aging mechanism for reactor vessel internal components considered are related to embrittlement, fatigue, corrosion, radiation induced creep, relaxation and swelling, and mechanical wear.

    The Agency's peer review service for radioactive waste management - known as the Waste Management Assessment and Technical Review Programme (WATRP) - started in 1989, building upon earlier types of advisory programmes. WATRP's international experts today provide advice and guidance on proposed or ongoing radioactive waste management programmes; planning, operation, or decommissioning of waste facilities; or on legislative, organizational, and regulatory matters. Specific topics often cover waste conditioning, storage, and disposal concepts or facilities; or technical and other aspects of ongoing or planned research and development programmes. The missions can thus contributed to improving waste management systems and plans, and in raising levels of public confidence in them, as part of IAEA efforts to assist countries in the safe management of radioactive wastes.

    The colon is the second most commonly injured intra-abdominal organ in penetrating trauma. Management of traumatic colon injuries has evolved significantly over the past 200 years. Traumatic colon injuries can have a wide spectrum of severity, presentation, and management options. There is strong evidence that most non-destructive colon injuries can be successfully managed with primary repair or primary anastomosis. The management of destructive colon injuries remains controversial with most favoring resection with primary anastomosis and others favor colonic diversion in specific circumstances. The historical management of traumatic colon injuries, common mechanisms of injury, demographics, presentation, assessment, diagnosis, management, and complications of traumatic colon injuries both in civilian and military practice are reviewed. The damage control revolution has added another layer of complexity to management with continued controversy.

    Purpose The purpose of this paper is to examine whether occupational health and safety (OHS) management used to manage musculoskeletal disorders (MSDs) in the aged care sector reflects contemporary research evidence of best practice to reduce the incidence of these disorders. Design/methodology/approach In total, 58 interviews were conducted with managers and supervisors in the aged care sector across four organisations in Australia. Policies and procedures relating to MSDs were reviewed for each organisation. Findings Policies and procedures for managing MSDs do not reflect contemporary evidence, which supports a complex aetiology, related to a range of physical and psychosocial workplace factors. Despite strong evidence that psychosocial factors contribute to MSD development, these were not included in the policies and procedures reviewed. Findings from the interviews management practices including leadership and various components of HRM were functioning well but fragmentation was evident due to the challenging nature of the aged care sector. Practical implications To address the significant burden of MSDs in the aged care sector, policies and procedures need to include coverage of psychosocial and physical workplace factors. The development of systematic and integrated OHS management at the workplace level may play an important role in the effective management of MSDs. Originality/value This study offers insights into the previously unexplored area of MSD risk management and the role of management practices such as HRM in the aged care sector.

Health professionals should take these into consideration when managing dermatological problems in elderly patients. Accordingly, current research is investigating the dermatological problems associated with the loss of cutaneous function with age. As cell renewal slows, the physical and chemical barrier function declines, cutaneous permeability increases, and the skin becomes increasingly vulnerable to external factors. In geriatric dermatology, the consequences of cutaneous aging lead to xerosis, skin folding, moisture-associated skin damage, and impaired wound healing. These problems pose significant challenges for both the elderly and their carers. Most often, nurses manage skin care in the elderly. However, until recently, little attention has been paid to developing appropriate, evidence-based, skincare protocols. The objective of this paper is to highlight common clinical problems with aging skin and provide some appropriate advice on cosmetic protocols for managing them. A review of the

    Adolescent idiopathic scoliosis (AIS) is a 3D spinal deformity affecting children between the ages of 11 and 18, without an identifiable etiology. The authors here reviewed the available literature to provide spine surgeons with a summary and update on current management options. Smaller thoracic and thoracolumbar curves can be managed conservatively with observation or bracing, but corrective surgery may be indicated for rapidly growing or larger curves. The authors summarize the atypical features to look for in patients who may warrant further investigation with MRI during diagnosis and review the fundamental principles of the surgical management of AIS. Patients with AIS can be managed very well with a combination of conservative and surgical options. Outcomes for these children are excellent with sustained longer-term results.

With the advent of new technologies, the physician has the opportunity of addressing these changes with the utilization of dermal fillers. Hyaluronic acid (HA dermal fillers are the most popular, non-permanent injectable materials available to physicians today for the correction of soft tissue defects of the face. This material provides an effective, non invasive, non surgical alternative for correction of the contour defects of the face due to its enormous ability to bind water and easiness of implantation. HA dermal fillers are safe and effective. The baby-boomer generation, and their desire of turning back the clock while enjoying an active lifestyle, has expanded the popularity of these fillers. In the US, there are currently eight HA dermal fillers approved for commercialization by the Food and Drug Administration (FDA. This article reviews the innate properties of FDA-approved HA fillers and provides an insight on future HA products and their utilization for the management of the aging face.Keywords: hyaluronic acid, aging face, dermal filler, wrinkles, Restylane, Perlane, Juvéderm

    Predictive and preventive maintenance technologies are increasingly of importance for the long term operation (LTO) of Light Water Reactor (LWR) plants. In order for the realization LTO to be successful, it is essential that aging degradation phenomena should be properly managed by using adequate maintenance programs based on foreseeing the aging phenomena and evaluating their rates of development, where Nuclear Power Plants can be continued to operate beyond the original design life depending upon the regulatory authority rules. In combination with Periodic Safety Review (PSR) and adequate maintenance program, a plant life can be extended to 60 years or more. Plant Life Management (PLiM) is based upon various maintenance program as well as systematic safety review updated based upon the state of the art of science and technology. One of the potential life time limiting issue would be materials ageing degradation and therefore an extensive efforts have been paid world-widely. In 2007, NISA launched a national program on Enhanced Ageing Management Program and 4 nationwide clusters were formed to carry out the national program where materials ageing degradation was one of the major topics. In addition to these degradation modes, one important activities in this program is proactive materials degradation management directed by the author which is a kind of the extension program of NRC PMDA program based upon more fundamental approach by a systematic elicitation by the experts nominated from all over the world. NISA program can be divided into two phases, one is from fiscal years (FY) 2006 - 2010 and the other FY 2011. Later phase is focusing more on System Safety due to Fukushima NPP accident. The main objectives of the Phase I is to evaluate potential and complex degradation phenomena and their mechanisms in order to identify future risks of component aging in nuclear power plants. The following items are of particular concern in this phase: (a) investigation of

The management system covers among others, management of structures, critical components inspections, the control command system and nuclear instrumentation verification. The paper presents also how maintenance and periodic testing are organized and managed in the reactor module. Practical examples of ageing management actions of some systems and components during recent years are presented. (author)

  6. A review of age dependent radioiodine dosimetry

    International Nuclear Information System (INIS)

    Johnson, J.R.

    1987-01-01

    Age dependent models of radioiodine metabolism in humans have been described. These models have been used to calculate age dependent committed doses to the thyroid from intakes of radioiodines. A model of fetal iodine metabolism is also described and used to calculate fetal thyroid doses from intakes of radioiodines by the mother. These doses are calculated using model parameter values thought to be representative of average for North American/European populations. Considerable variability from these results can be expected for individuals. In addition, population with significant differences in stable iodine intake, and in body parameters, will have model parameters somewhat different than the ones described in this paper. These different model parameters will result in different doses from intakes of radioiodines, but it is doubtful if the differences in population would be as large as the variation between individuals. 25 refs.; 11 figs.; 1 table

    Simola, K.

    1999-01-01

    The aim of nuclear power plant ageing management is to maintain an adequate safety level throughout the lifetime of the plant. In ageing studies, the reliability of components, systems and structures is evaluated taking into account the possible time-dependent degradation. The phases of ageing analyses are generally the identification of critical components, identification and evaluation of ageing effects, and development of mitigation methods. This thesis focuses on the use of reliability methods and analyses of plant- specific operating experience in nuclear power plant ageing studies. The presented applications and method development have been related to nuclear power plants, but many of the approaches can also be applied outside the nuclear industry. The thesis consists of a summary and seven publications. The summary provides an overview of ageing management and discusses the role of reliability methods in ageing analyses. In the publications, practical applications and method development are described in more detail. The application areas at component and system level are motor-operated valves and protection automation systems, for which experience-based ageing analyses have been demonstrated. Furthermore, Bayesian ageing models for repairable components have been developed, and the management of ageing by improving maintenance practices is discussed. Recommendations for improvement of plant information management in order to facilitate ageing analyses are also given. The evaluation and mitigation of ageing effects on structural components is addressed by promoting the use of probabilistic modelling of crack growth, and developing models for evaluation of the reliability of inspection results.

    Older people often experience loss of appetite and/or decreased food intake that, unavoidably, impact energy metabolism and overall health status. The association of age-related nutritional deficits with several adverse outcomes has led to the recognition of a geriatric condition referred to as "anorexia of aging." Anorexia is an independent predictor of morbidity and mortality both in the community and across clinical settings. Multidimensional interventions within personalized care plans currently represent the most effective option to ensure the provision of adequate amounts of food, limit weight loss, and prevent adverse health outcomes in older adults.

    The uranium enrichment enterprise of the US Department of Energy (DOE) provides enriched nuclear fuel for private and government utilities domestically and abroad. The enterprise, in effect, provides a commercial service and represents a signficant business operation within the US government: more than $1 billion in revenues annually and future capital expenditures estimated at several billions of dollars. As a result, in May 1980, the Assistant Secretary for Resource Applications within DOE requested that a group of experienced business executives be assembled to review the operation, financing, and management of the uranium enrichment enterprise as a basis for advising the Secretary of Energy. The review group was specifically asked to focus on the management activities to which sound business practices could be applied. The group developed findings and recommendations in six areas: management of operations and construction; long-range planning; marketing of enrichment services; financial management; research and development; and general management. The chapters of this report present first the management review group's recommendations in the six areas evaluated and then the findings and issues in each area. An appendix provides the group's calendar of meetings. A list of major reference sources used in the course of the study is also included. 12 references

    Full Text Available One of the most common co-morbidities of cerebrovascular disorders is neuroinflammation, a hallmark and decisive contributor to many central nervous system (CNS diseases. Although neuropathological conditions differ in etiology and in the way in which the inflammatory response is mounted, cellular and molecular mechanisms of neuroinflammation are probably similar in aging, hypertension, depression and cognitive impairment or after cerebral insult such as stroke. Moreover, a number of highly prevalent risk factors such as hypertension, diabetes and atherosclerosis are increasingly understood to act as “silent contributors” to neuroinflammation – not only establishing the condition as a central pathophysiological mechanism, but also constantly fuelling it. Mild, but continuous neuroinflammation can provide the ground for disorders such as cerebral small vessel disease (cSVD and subsequent dementia. Acute neuroinflammation, often in the context of traumatic or ischemic CNS lesions, aggravates the acute damage and can lead to depression, post-stroke dementia and neurodegeneration. All of these sequelae impair recovery and provide the ground for further cerebrovascular events. http://dx.doi.org/10.7175/rhc.v6i2.1170

    Full Text Available Although there are many potential benefits associated with the use of virtual product development teams, exploiting these benefits requires an appropriate management. Managing virtual product development team is a critical issue as many of these teams fail to accomplish their goals. Review of previous literature shows that body of knowledge in managing virtual product development teams is fragmented and inconsistent. The main objective of this paper is to categorize the previous research on the subject of virtual product development team management in order to integrate the research into a thematic model and to enable recommendations for future research. So, this study reviews and summarizes empirical research in the field, also conceptual and qualitative papers, experiences, reports and explorative case studies. Results show that there are three fields of research in this area, including: Virtual production and Virtual team in Product Development, Managing virtual team in R&D[1] and product development, Managing global virtual product development teams. In order to organize previous studies in this area, a thematic map is proposed which shows the structure and sequence of research. Finally, a comprehensive discussion on the future directions in this field is proposed.

    Medication reviews is a widely accepted approach known to have a substantial impact on patients' pharmacotherapy and safety. Numerous options to optimise pharmacotherapy in older people have been reported in literature and they include medication reviews, computerised decision support systems, management teams, and educational approaches. Pharmacist-led medication reviews are increasingly being conducted, aimed at attaining patient safety and medication optimisation. Cost effectiveness is an essential aspect of a medication review evaluation. Areas covered: A systematic searching of articles that examined the cost-effectiveness of medication reviews conducted in aged care facilities was performed using the relevant databases. Pharmacist-led medication reviews confer many benefits such as attainment of biomarker targets for improved clinical outcomes, and other clinical parameters, as well as depict concrete financial advantages in terms of decrement in total medication costs and associated cost savings. Expert commentary: The cost-effectiveness of medication reviews are more consequential than ever before. A critical evaluation of pharmacist-led medication reviews in residential aged care facilities from an economical aspect is crucial in determining if the time, effort, and direct and indirect costs involved in the review rationalise the significance of conducting medication reviews for older people in aged care facilities.

    The reactor coolant system (RCS) mechanical components that require an aging management review for license renewal include the primary loop piping and associated connections to other support systems, reactor vessel, reactor vessel internals, pressurizer. steam generators, reactor coolant pumps, and all other inter-connected piping, pipe fittings, valves, and bolting. All major RCS components are located inside the reactor building. Based on the evaluation findings of recently submitted license renewal applications for pressurized water reactors, this paper presents the plant programs and/or activities proposed by the applicants to manage the effects of aging. These programs and/or activities provide reasonable assurance that the intended function(s) of these mechanical components will be maintained for the period of extended operation. The license renewal application includes identification of RCS subcomponents that are within the scope of license renewal and are vulnerable to age-related degradation when exposed to environmental and operational conditions. determination of the effects of aging on their intended safety functions. and implementation of the aging management programs and/or activities including both current and new programs. Industry-wide operating experience, including generic communication by the NRC, is part of the aging management review for the RCS components. In addition, this paper discusses time-limited aging analyses associated with neutron embrittlement of the reactor vessel beltline region and thermal fatigue

    The theory and technology of equipment aging is reviewed, particularly as they relate to the qualification of safety-system equipment for nuclear power generating stations. A fundamental degradation model is developed, and its relation to more restricted models (e.g., Arrhenius and inverse-stress models) is shown. The most common theoretical and empirical models of aging are introduced, and limitations on their practical application are analyzed. Reliability theory and its application to the acceleration of aging are also discussed. A compendium of aging data for materials and components, including degradation mechanisms, failure modes and activation energies, is included.

    The use of human subjects for medical research in most industrialized nations requires the scientific and ethical scrutiny of research proposals by a governing institutional review board (IRB) or its equivalent. As part of their primary charge to protect human subjects, IRBs are responsible for the regulatory oversight of not only the research protocol itself but also the research conduct of the investigators and, if applicable, the funding sponsor. This article will discuss the regulatory requirements for an accurate account of IRB protocols and investigators and present an overview of the general flow of information for an IRB protocol. The current and potential uses of information management systems by IRBs will also be reviewed and accompanied by a discussion of the potential advantages and disadvantages of various computerized information systems for management of clinical research.

  15. Prudency reviews, cash management issues emerge

    Utility management is paying increasing attention to the broadening of regulatory commission prudency reviews to cover operating generating plants as well as those under construction. Utilities can expect a prudency review after a major outage, and should investigate the possibility for legal action against a third party or be prepared to defend itself. The Shoreham nuclear plant serves as a warning to utilities of the need for on-going documentation of cost-benefit analyses conducted during the construction period. Utility managers should demand a prudency standard from their regulators, and minority owners in large projects should make independent prudency findings. There is also a growing need for utilities to develop intelligent strategies for handling excess cash. Methods for handling cash flow include the financial investment, grid refurbishment, dividend payout, decapitalization, and diversification

    One of the requirements for nuclear plant license renewal may be the establishment and demonstration of an effective aging management program. An analysis of both qualitative and quantitative information will be required to define the contents of this aging management program. The authors propose two quantitative figures of merit, Mean Event Detection Frequency and Mean Renewal Rate, that can be used to compare the effectiveness of various inspection, surveillance, test, and monitoring (ISTM) activities for aging mitigation. An example showing the relative effectiveness of an enhanced Loose Parts Monitoring System with current ISTM activities for steam generators and reactor internals is provided. (author)

    Lofaro, R.J.

    1999-01-01

    As commercial nuclear power plants approach the end of their original license period, some utilities are considering the possibility of license renewal. The requirements for applying for license renewal are specified in the License Renewal Rule, which is in Title 10 of the Code of Federal Regulations, Part 54 (10 CFR54). Among the requirements specified in the rule is the performance of an Integrated Plant Assessment (IPA) which identifies and lists structures and components subject to an aging management review. The intent of this requirement is to ensure that aging degradation will not adversely affect plant safety during the license renewal period. The aging management review includes an identification of the aging effects and monitoring programs for components within the scope of the rule. Among the components within the scope are electric cables since they are passive, long-lived components that are not replaced on a periodic basis. This paper examines the aging causes and effects of electric cables, along with the programs that are typically used to ensure that proper aging management practices are in place to monitor and mitigate the effects of aging on electric cables

    Inspection and maintenance activities for air conditioning facilities within the plant are managed mainly for active facilities, and as the years of operation pass, a method for detecting in advance aging-related integrity problems of passive facilities and taking necessary measures against them is required. Therefore, this paper establishes a standard aging management guideline for air conditioning facilities by selecting systems for which those facilities are to be managed, analyzing degradation mechanisms and reviewing the current status of aging degradation management. According to the review of additional equipment-specific aging degradation mechanisms and the current status of management to apply the aging degradation program to air conditioning facilities, it has been found that internal and external visual inspection procedures for fans, dampers, coils, filters and housings have to be added. It has been confirmed that among additional equipment s, fire dampers, fan bearings and belts and air cleaning/conditioning units with charcoal filters do not require additional inspection as they are periodically inspected. It has been found, however, that air cleaning/conditioning units without charcoal filters are to be inspected along with fans, ducts and coils

    Researchers and water managers have turned to green stormwater infrastructure, such as bioswales, retention basins, wetlands, rain gardens, and urban green spaces to reduce flooding, augment surface water supplies, recharge groundwater, and improve water quality. It is increasingly clear that green stormwater infrastructure not only controls stormwater volume and timing, but also promotes ecosystem services, which are the benefits that ecosystems provide to humans. Yet there has been little synthesis focused on understanding how green stormwater management affects ecosystem services. The objectives of this paper are to review and synthesize published literature on ecosystem services and green stormwater infrastructure and identify gaps in research and understanding, establishing a foundation for research at the intersection of ecosystems services and green stormwater management. We reviewed 170 publications on stormwater management and ecosystem services, and summarized the state-of-the-science categorized by the four types of ecosystem services. Major findings show that: (1) most research was conducted at the parcel-scale and should expand to larger scales to more closely understand green stormwater infrastructure impacts, (2) nearly a third of papers developed frameworks for implementing green stormwater infrastructure and highlighted barriers, (3) papers discussed ecosystem services, but less than 40% quantified ecosystem services, (4) no geographic trends emerged, indicating interest in applying green stormwater infrastructure across different contexts, (5) studies increasingly integrate engineering, physical science, and social science approaches for holistic understanding, and (6) standardizing green stormwater infrastructure terminology would provide a more cohesive field of study than the diverse and often redundant terminology currently in use. We recommend that future research provide metrics and quantify ecosystem services, integrate disciplines to

  3. A review of asphalt and asphalt mixture aging

    2013-01-01

    Full Text Available This paper presents an extensive review of the pertinent literature regarding asphalt and asphalt mixture Aging. Aging affects flexible pavement performance and is produced by intrinsic and extrinsic variables as well as exposure time. Intrinsic variables include asphalt and aggregate properties, a mixture’s asphalt content, binder film thickness and air void content; extrinsic variables are associated with production (short-term aging and exposure to environmental field conditions (long-term aging. Taken together, both variables demonstrate that aging results from three distinct mechanisms: volatilisation, oxidation and steric hardening. Temperature, pressure and photo degradation treatments are used to simulate aging in the laboratory and empirical and semi-empirical models are created to represent and study aging. Aging increases asphalt complex modulus and decreases the phase angle. Mixtures become stiffer while fatigue life becomes reduced. Carbonyl and sulfoxide group formation in asphalt are often studied as such chemical changes show oxidation in aged asphalts. The prevailing models used to predict asphalt aging are discussed, though more comprehensive research into asphalt aging is still needed.

    The study of the degradation of structures, components, and systems due to aging is an important ongoing area of research in the nuclear industry. Efforts by the U.S. Nuclear Regulatory Commission (NRC) and the utility industry, through organizations such as the Electric Power Research Institute (EPRI), have produced substantial research results that can be used by inspectors and operators to effectively understand and manage the aging of nuclear power plants. One of the primary objectives of the NRC's Nuclear Plant Aging Research (NPAR) Program is to determine how aging affects the safety of nuclear power plants. This program uses operating experience, testing, and engineering analysis to identify failures caused by age-related degradation. Useful information on aging has also resulted from research being performed by the industry to support plant-life extension (PLEX). The EPRI program, for instance, is directed toward the resolution of issues related to materials and components. Degradation of equipment and systems due to aging can occur which, if unmitigated, could result in reduction of the nuclear power plant safety margin as the plant ages. This paper describes how aging research results may be used by plant operating management to effectively address the aging issue and by inspectors responsible for monitoring plant activities and programs

    Electrical cables constitute one of the most important components of NPP in terms o maintenance, safety and availability of the plant. Due to their large extension (thousands of kilometers) it is impossible to fully replace them and aging management becomes essential for long term operation of NPP. Since Atucha II is under construction there was a good opportunity to establish and implement a holistic cable aging management program from the beginning according to the state of the art in this field. The scope of this program involves safety related cables, including EQ cables and non EQ cables as well. Due to the diversity of the installed cables is impossible to address an aging management program of every single specimen. However it is possible to establish 'cables families' of similar aging behavior based on insulation and jacket material, manufacture, etc Several aging management strategies were set for the different 'cables families'. These strategies include cables deposit in plant, elaboration of procedures of visual and tactile inspection, NDE techniques, etc Currently the aging management program is being implemented covering topic such as: Cable screening and grouping. Review of EQ documentation and conventional qualification information referring to the installed cables. Establishment of base line of condition monitoring techniques. Calibration and set up of test parameters for NDE techniques. Aging mechanism characterization and determination of. Design construction and installation of cable deposit in plant (author)

    2011-01-01

    A review of the Pennsylvania Game Commission's (PGC) deer management program and public concern about predator impacts on deer (Odocoileus virginianus) populations compelled the PGC to investigate the role of age ratios in developing management recommendations. Age ratios, such as proportion of juveniles in the antlerless harvest, may provide an index to population productivity and predator impacts. We estimated proportion of juveniles in the antlerless harvest from hunter-killed deer, population trends using the Pennsylvania (USA) sex–age–kill model, and reproduction from road-killed females. Using these estimates and a simulation model, we concluded that no single age-ratio value would serve as a reliable measure of population status. Wildlife Management Unit-specific trends in proportion of juveniles in the antlerless harvest and population trends provided the most relevant management information. We also provide an example decision chart to guide management actions in response to declining age ratios in the harvest. Although predator management activities and juvenile survival studies are often desired by the public, our decision-chart example indicated a number of deer management options exist before investing resources in predator management activities and juvenile survival studies.

    The aim of this study was to explore and understand the complexity of ageing in relation to factors of importance for extending working life. Discourse analysis of documents was used in an integrative review including 128 articles. Four different conceptualisation of ageing are shown to affect older workers' ability to extend their working life: (a) biological ageing people's health in relation to their physical and mental work environment, their pace of work and recuperation needs; (b) chronological ageing statutory retirement age and policies and economic incentives devised for older workers by society, unions and organisations/enterprises; (c) social ageing inclusion in different social groups, the attitude of managers, organisations and family members, the leisure activities and surrounding environment; and (d) mental/cognitive ageing self-crediting, motivating and meaningful activities, competence and skills in working life. CONCLUSIONS SOCIETIES TODAY FOCUS MOSTLY ON CHRONOLOGICAL AGEING AND ARE LOOKING TO INCREASE THE RETIREMENT AGE WITH REGARD TO STATUTORY PENSION SYSTEMS, EG BEYOND 65 YEARS OF AGE THE INTER-RELATIONSHIPS BETWEEN CHRONOLOGICAL, MENTAL, BIOLOGICAL AND SOCIAL AGEING AND THE NINE AREAS IDENTIFIED AS BEING IMPORTANT TO OLDER WORKERS IN THESE RESPECTS NEED TO BE CONSIDERED WHEN AIMING TO PROVIDE A SUSTAINABLE WORKING LIFE FOR THE INCREASING NUMBERS OF OLDER WORKERS IN MODERN SOCIETY THE THEORETICAL MODEL DEVELOPED IS A CONTRIBUTION TO THE CRITICAL DEBATE THAT CAN BE APPLIED BY SOCIETIES, EMPLOYERS AND MANAGERS IN ORDER TO PROVIDE OLDER WORKERS WITH AN INCLUSIVE AND SUSTAINABLE EXTENDED WORKING LIFE. © 2016 the Nordic Societies of Public Health.

  8. Household hazardous waste management: a review.

    Inglezakis, Vassilis J; Moustakas, Konstantinos

    2015-03-01

    This paper deals with the waste stream of household hazardous waste (HHW) presenting existing management systems, legislation overview and other relevant quantitative and qualitative information. European Union legislation and international management schemes are summarized and presented in a concise manner by the use of diagrams in order to provide crucial information on HHW. Furthermore, sources and types, numerical figures about generation, collection and relevant management costs are within the scope of the present paper. The review shows that the term used to refer to hazardous waste generated in households is not clearly defined in legislation, while there is absence of specific acts regulating the management of HHW. The lack of obligation to segregate HHW from the household waste and the different terminology used makes it difficult to determine the quantities and composition of this waste stream, while its generation amount is relatively small and, therefore, is commonly overlooked in waste statistics. The paper aims to cover the gap in the related literature on a subject that is included within the crucial waste management challenges at world level, considering that HHW can also have impact on other waste streams by altering the redox conditions or causing direct reactions with other non hazardous waste substances.

  9. Evidence-based management: a literature review.

    2002-05-01

    This paper presents a review of evidence-based management (EBM), exploring whether management activities within healthcare have been, or can be, subject to the same scientific framework as clinical practice. The evidence-based approach was initially examined, noting the hierarchy of evidence ranging from randomized control trials to clinical anecdote. The literature varied in its degree of criticism of this approach; the most common concern referring to the assumed superiority of positivism. However, evidence-based practice was generally accepted as the best way forward. Stewart (1998) offered the only detailed exposition of EBM, outlining a necessary 'attitude of mind' both for EBM and for the creation of a research culture. However, the term 'clinical effectiveness' emerged as a possible replacement buzz-word for EBM (McClarey 1998). The term appears to encompass the sentiments of the evidence-based approach, but with a concomitant concern for economic factors. In this paper the author has examined the divide between those who viewed EBM as an activity for managers to make their own practice accountable and those who believed it to be a facilitative practice to help clinicians with evidence-based practice. Most papers acknowledged the limited research base for management activities within the health service and offered some explanation such as government policy constraints and lack of time. Nevertheless, the overall emphasis is that ideally there should be a management culture firmly based in evidence.

  10. A Review of Transformer Aging and Control Strategies

    2017-09-19

    Transformer aging is an important challenge in power system. Distribution transformers themselves are minimally controllable, but smart meters provide excellent, new insights into electrical loads, which insights can be used to understand and mitigate transformer aging. The nature of transformer loads is changing with the integration of distributed energy resources (DERs) and electric vehicles (EVs). This paper first reviews factors that influence the aging of distribution transformers, including root causes of transformer failure. Existing and proposed load control methods are then discussed. A distribution model is introduced to help evaluate potential control methods.

    2012-01-01

    A Plant-wide and systematic Aging and Plant Life Management is essential for the safe operation and/or availability of nuclear power plants. The Aging Management (AM) has the objective to monitor and control degradation effects for safety relevant Systems, Structures and Components (SSCs) which may compromise safety functions of the plant. The Plant Life Management (PLM) methodology also includes aging surveillance for availability relevant SSCs. AM and PLM cover mechanical components, electrical and I and C systems and civil structures All Aging and Plant Life Management rules call for a comprehensive approach, requiring the systematic collection of various aging and safety relevant data on a plant-wide basis. This data needs to be serviced and periodically evaluated. Due to the complexity of the process, this activity needs to be supported by a qualified software tool for the management of aging relevant data and associated documents (approx. 30 000 SSCs). In order to support the power plant operators AREVA NP has developed the software tool COMSY. The COMSY software with its integrated AM modules enables the design and setup of a knowledge-based power plant model compatible to the requirements of international and national rules (e.g. IAEA Safety Guide NS-G-2.12, KTA 1403). In this process, a key task is to identify and monitor degradation mechanisms. For this purpose the COMSY tool provides prognosis and trending functions, which are based on more than 30 years of experience in the evaluation of degradation effects and numerous experimental studies. Since 1998 COMSY has been applied successfully in more than fifty reactor units in this field. The current version 3.0 was revised completely and offers additional AM functions. All aging-relevant component data are compiled and allocated via an integrated power plant model. Owing to existing interfaces to other software solutions and flexible import functions, COMSY is highly compatible with already existing data

    Broadly speaking, supervised machine learning is the computational task of learning correlations between variables in annotated data (the training set), and using this information to create a predictive model capable of inferring annotations for new data, whose annotations are not known. Ageing is a complex process that affects nearly all animal species. This process can be studied at several levels of abstraction, in different organisms and with different objectives in mind. Not surprisingly, the diversity of the supervised machine learning algorithms applied to answer biological questions reflects the complexities of the underlying ageing processes being studied. Many works using supervised machine learning to study the ageing process have been recently published, so it is timely to review these works, to discuss their main findings and weaknesses. In summary, the main findings of the reviewed papers are: the link between specific types of DNA repair and ageing; ageing-related proteins tend to be highly connected and seem to play a central role in molecular pathways; ageing/longevity is linked with autophagy and apoptosis, nutrient receptor genes, and copper and iron ion transport. Additionally, several biomarkers of ageing were found by machine learning. Despite some interesting machine learning results, we also identified a weakness of current works on this topic: only one of the reviewed papers has corroborated the computational results of machine learning algorithms through wet-lab experiments. In conclusion, supervised machine learning has contributed to advance our knowledge and has provided novel insights on ageing, yet future work should have a greater emphasis in validating the predictions.

    Aging phenomena was raised as an important issue at GAS-MPR after having some component degradation reported within its ten years operational record. This phenomena was anticipated by developing a program of aging management, where its purpose is to prevent an enlargement of degradation of the systems and components and failure. The aging managements include identification of system and component which have aging process enlargement and impact to the reactor operational safety, developing operational operation and maintenance practices, developing operational and maintenance data base, developing predictive maintenance program, and identifying and studying method and technology for inspection, testing, and surveillance. The result of studying on method and technology of testing, surveillance, and diagnostic conclude that FFT based noise spectrum analysis can be used to detect an anomaly of system and component performance. This analysis will be developed in the future using Auto Regressive Method, Kalman Filter, and Neural Network. (author)

    Tarapur Atomic Power Station, the longest serving Nuclear Power Plant in the Asian continent has completed 36 years of successful operation and generated more than 70,000 million units of electric power. Built in late sixties, with the state-of-the-art safety features prevailing then, TAPS through the process of evolution has become safer plant due to efforts of upgradation, renovation and refurbishment prompted by the station's operating experience, feed back from overseas reactors, lessons learnt from nuclear incidents, accidents and fresh review of design basis and safety analysis of the plant. All components of a Nuclear power plant experience some degradation with time. The Reactor Pressure Vessels (RPV) designed for 40 effective full power years (EFPY) of operation have operated for less than 20 EFPY and the material condition is assessed to be fit for some more years of service. The condition of the containment and main plant buildings was assessed to be satisfactory. The Ageing Management Programme (AMP) involved identification of key systems, structures and components (SSCs) that may experience degradation due to ageing, and take corrective measures through maintenance, repair and/or replacement. The identified components were classified as major critical components, important systems and other critical components. For each component mode of degradation was identified, ageing assessment was done and action plan was finalized. Replacement of some important equipment like 3 x 50 % capacity Emergency Diesel Generators (EDG) with 3 x 100 % capacity EDG, Salt Service Water (SSW) pumps, Control rod drive (CRD) pumps, Emergency Condenser tube bundles, Station battery has been done on the basis of condition monitoring and to obviate common cause failure and enhance the system reliability. Samples of Safety related cables were subjected to residual life assessment (RLA) and replacement action firmed up on the basis of the RLA findings. Condition survey of Main

    Bone quality encompasses all the characteristics of bone that, in addition to density, contribute to its resistance to fracture. In this review, we consider changes in architecture, porosity, and composition, including collagen structure, mineral composition, and crystal size. These factors all are known to vary with tissue and animal ages, and health status. Bone morphology and presence of microcracks, which also contribute to bone quality, will not be discussed in this review. Correlations with mechanical performance for collagen cross-linking, crystallinity, and carbonate content are contrasted with mineral content. Age-dependent changes in humans and rodents are discussed in relation to rodent models of disease. Examples are osteoporosis, osteomalacia, osteogenesis imperfecta (OI), and osteopetrosis in both humans and animal models. Each of these conditions, along with aging, is associated with increased fracture risk for distinct reasons. © 2017 New York Academy of Sciences.

    2017-01-01

    Full Text Available The move towards automated driving is gaining ground. This paper reviews the development process of self-driving technology and discusses the safety and efficiency advantages of autonomous vehicles. The discussion shows that the existing traffic management system, including transport infrastructures and regulations, should be changed accordingly to maximize the advantages of autonomous driving. Thus, this paper subsequently gives an insight of the traffic management from three aspects: fully self-driving traffic infrastructures, mixed traffic infrastructures and regulations. First, it is summarized in detail what should be adjusted in intersections, parking lots, pedestrian crossings, ramps, signs and markings. With the transformation of traffic infrastructures, the advantages of driverless car will be more pronounced on account of increased capacity, reduced delay and land use. Also, this paper indicates that the implementations of strict product liability for self-driving car manufacturers and no-fault tort liability for users are applicable to automated vehicle accidents.

    Cheong, Ju Yong; Keshava, Anil

    2017-07-01

    Traumatic colorectal injuries are common during times of military conflict, and major improvements in their care have arisen in such periods. Since World War II, many classification systems for colorectal trauma have been proposed, including (i) Flint Grading System; (ii) Penetrating Abdominal Trauma Index; (iii) Colonic/Rectal Injury Scale; and (iv) destructive/non-destructive colonic injuries. The primary goal of these classifications was to aid surgical management and, more particularly, to determine whether a primary repair or faecal diversion should be performed. Primary repair is now the preferred surgical option. Patients who have been identified as having destructive injuries have been found to have higher anastomotic leak rates after a primary repair. Damage control principles need to be adhered to in surgical decision-making. In this review, we discuss the mechanisms of injury, classifications, clinical presentation and current recommendations for the management of colorectal trauma. © 2017 Royal Australasian College of Surgeons.

Based on episode history and pathophysiology, priapism is classified into three subtypes: ischemic (low-flow, non-ischemic (high-flow, and stuttering priapism. Ischemic priapism is characterized by a persistent, painful erection with remarkable rigidity of the corpora cavernosa caused by a disorder of venous blood outflow from this tissue mass, and is similar to penile compartment syndrome. Stuttering priapism is characterized by a self-limited, recurrent, and intermittent erection, frequently occurring in patients with sickle cell disease. Non-ischemic priapism is characterized by a painless, persistent nonsexual erection that is not fully rigid and is caused by excess arterial blood flow into the corpora cavernosa. Because ischemic and non-ischemic priapism differ based on emergency status and treatment options, appropriate discrimination of each type of priapism is required to initiate adequate clinical management. The goal of management of priapism is to achieve detumescence of the persistent penile erection and to preserve erectile function after resolution of the priapism. To achieve successful management, urologists should address this emergency clinical condition. In the present article, we review the diagnosis and clinical management of the three types of priapism.

    There is a consensus that the aging population is beginning to impact on many facets of our life. They have more medical problems and the potential to "drain" the focus of the medical community, as well as national budgets with their accompanying medical bills. Personal strategies related to active aging will help us to better understand and identify how older adults in Europe prepare themselves for the natural process of aging and what are their personal approaches to active aging. The objective of this review was to synthesize the best available evidence regarding the older adult's perspective on the personal strategies related to active aging among older adults in Europe. This review considered studies that included older adults (age over 55 years) who live in Europe. This review considered studies that investigated older adults' perspectives on (any) personal strategies related to active aging. Europe (considering "some similarity" in health care systems and retirement policies). This review considered any qualitative designs. A three-step search strategy was used to identify published and unpublished studies. The extensive search process was conducted in October 2014 and considered published and unpublished studies from the inception of databases until October 2014. Studies published in any language which had an abstract in English, Czech and Slovak languages were considered for inclusion in this review. Studies were appraised for methodological quality by two independent reviewers using the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). Data were extracted from the papers included in the review by two independent reviewers using the standardized JBI-QARI data extraction tool. Data synthesis was performed using the meta-aggregation approach of meta-synthesis recommended by the Joanna Briggs Institute. Fourteen studies were included in this systematic review. From these 14 studies, 42 findings were extracted; findings were

    The paper reviews the existing generic aging management programs (AMPs) for the reactor coolant system (RCS) components in boiling water reactors (BWRs), including the reactor pressure vessel and internals, the reactor recirculation system, and the connected piping. These programs have been evaluated in the U.S. Nuclear Regulatory Commission (NRC) report, Generic Aging Lessons Learned (GALL), NUREG-1801, for their use in the license renewal process to manage several aging effects, including loss of material, crack initiation and growth, loss of fracture toughness, loss of preload, wall thinning, and cumulative fatigue damage. The program evaluation includes a review of ten attributes (scope of program, preventive actions, parameters monitored/inspected, detection of aging effects, monitoring and trending, acceptance criteria, corrective actions, confirmative process, administrative control, and operating experience) for their effectiveness in managing a specific aging effect in a given component(s). The generic programs are based on the ASME Section XI inservice inspection requirements; industry guidelines for inspection and evaluation of aging effects in BWR reactor vessel, internals, and recirculation piping; monitoring and control of BWR water chemistry; and operating experience as reported in the USNRC generic communications and industry reports. The review concludes that all generic AMPs are acceptable for managing aging effects in BWR RCS components during an extended period of operation and do not need further evaluation. However, the plant-specific programs for managing aging in certain RCS components during an extended period of operation do require further evaluation. For some plant-specific AMPs, the GALL report recommends an aging management activity to verify their effectiveness. An example of such an activity is a one-time inspection of Class 1 small-bore piping to ensure that service-induced weld cracking is not occurring in the piping. Several of

    Systematic reviews comprehensively summarize evidence about the effectiveness of conservation interventions. We investigated the contribution to management decisions made by this growing body of literature. We identified 43 systematic reviews of conservation evidence, 23 of which drew some concrete conclusions relevant to management. Most reviews addressed conservation interventions relevant to policy decisions; only 35% considered practical on-the-ground management interventions. The majority of reviews covered only a small fraction of the geographic and taxonomic breadth they aimed to address (median = 13% of relevant countries and 16% of relevant taxa). The likelihood that reviews contained at least some implications for management tended to increase as geographic coverage increased and to decline as taxonomic breadth increased. These results suggest the breadth of a systematic review requires careful consideration. Reviews identified a mean of 312 relevant primary studies but excluded 88% of these because of deficiencies in design or a failure to meet other inclusion criteria. Reviews summarized on average 284 data sets and 112 years of research activity, yet the likelihood that their results had at least some implications for management did not increase as the amount of primary research summarized increased. In some cases, conclusions were elusive despite the inclusion of hundreds of data sets and years of cumulative research activity. Systematic reviews are an important part of the conservation decision making tool kit, although we believe the benefits of systematic reviews could be significantly enhanced by increasing the number of reviews focused on questions of direct relevance to on-the-ground managers; defining a more focused geographic and taxonomic breadth that better reflects available data; including a broader range of evidence types; and appraising the cost-effectiveness of interventions.

    Over recent years the electric power generating community has acknowledged the importance of the aging process on plant safety and availability. To cope with time-dependent degradation phenomenon that can affect active as well as passive components and lead to unacceptable, unanticipated failures requires research into the mechanisms of the aging process, advances in productive methods for assessing the aging impact on risk and availability, and a better understanding of power plant operations so that strategies for defending against this pervasive stress can be developed. This paper discusses current research advances and presents a framework to aid in the systematic integration of these three needs. As such it is anchored to research being conducted at Brookhaven National Laboratory in the areas of plant aging, life extension, reliability, performance indication, and risk assessment. The current question facing the industry can be simply stated. ''How can an acceptable level of safety and availability be maintained throughout the operational life of a nuclear power plant?'' The complexity of this question indicates that managing aging effects must be a continuous, coordinated process integrated with day-to-day tactical plant operation decisions. This implies that aging and reliability programs must be systemic properties of an organization's management, and that research into aging technology must be closely linked

    Eight percent of Australians aged 65 years and over receive residential aged care each year. Residents are increasingly older, frailer and have complex care needs on entry to residential aged care. Up to 63% of Australian residents of aged care facilities take nine or more medications regularly. Together, these factors place residents at high risk of adverse drug events. This paper reviews medication-related policies, practices and research in Australian residential aged care. Complex processes underpin prescribing, supply and administration of medications in aged care facilities. A broad range of policies and resources are available to assist health professionals, aged care facilities and residents to optimise medication management. These include national guiding principles, a standardised national medication chart, clinical medication reviews and facility accreditation standards. Recent Australian interventions have improved medication use in residential aged care facilities. Generating evidence for prescribing and deprescribing that is specific to residential aged care, health workforce reform, medication-related quality indicators and inter-professional education in aged care are important steps toward optimising medication use in this setting.

    The purpose of this study was to review the evidence of the economic burden of falls in old age. This review showed that falls are a relevant economic burden. Efforts should be directed to fall-prevention programmes. Falls are a common mechanism of injury and a leading cause of costs of injury in the elderly. The purpose of this study was to review for the first time the evidence of the economic burden caused by falls in old age. A systematic review was conducted in the databases of PubMed, of the Centre for Reviews and Dissemination and in the Cochrane Database of Systematic Reviews until June 2009. Studies were assessed for inclusion, classified and synthesised. Costs per inhabitant, the share of fall-related costs in total health care expenditures and in gross domestic products (GDP) were calculated. If appropriate, cost data were inflated to the year 2006 and converted to US Dollar (USD PPP). A total of 32 studies were included. National fall-related costs of prevalence-based studies were between 0.85% and 1.5% of the total health care expenditures, 0.07% to 0.20% of the GDP and ranged from 113 to 547 USD PPP per inhabitant. Direct costs occurred especially in higher age groups, in females, in hospitals and long-term care facilities and for fractures. Mean costs per fall victim, per fall and per fall-related hospitalisation ranged from 2,044 to 25,955; 1,059 to 10,913 and 5,654 to 42,840 USD PPP and depended on fall severity. A more detailed comparison is restricted by the limited number of studies. Falls are a relevant economic burden to society. Efforts should be directed to economic evaluations of fall-prevention programmes aiming at reducing fall-related fractures, which contribute substantially to fall-related costs.

    Age-related degradation mechanisms of key components are subject to aging management review by utilities considering plant license renewal. The management of aging effects in PWR internals must be demonstrated as specified in the US NRC Standard Review. The US NRC staff has also issued a Generic Aging Lessons Learned (GALL) report that documents the staff's basis for determining when existing generic programs are adequate to manage aging without change and when existing generic programs should be augmented for license renewal. The EPRI Materials Reliability Program (MRP) has been conducting studies to develop technical bases and guidelines to support aging management of PWR internals, with a particular attention to utility License Renewal commitments. The strategic approach taken by the MRP includes: developing an overall aging management framework, defining degradation mechanism screening values, categorizing and ranking internals components based on screening, performing functionality analyses and safety evaluation, and developing inspection and evaluation guidelines associated with each category of components. Screening criteria are developed for the following potential internals degradation mechanisms: - Stress Corrosion Cracking [Excluding Irradiation Effects]; - Irradiation-Assisted Stress Corrosion Cracking; - Thermal Aging Embrittlement; - Irradiation Embrittlement; - Void Swelling; - Stress Relaxation and Creep [Irradiation-enhanced]; - Wear; - Fatigue. The ranking and categorization calls to bin internals components into four categories: - Category A: component items for which aging degradation significance is minimal and aging effects are below the screening criteria; - Category C: 'lead' component items for which aging degradation significance is high or moderate and aging effects are above screening levels; - Category B: component items above screening levels but are not 'lead' component items and aging degradation significance

    A plant's maintenance program is the principal vehicle through which age-related degradation is managed. From 1988 to 1991, the NRC evaluated the maintenance program of every nuclear power plant in the United States. Forty-four out of a total of sixty-seven of the reports issued on these in-depth team inspections have been reviewed for insights into the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear plant structures, systems, and components (SSCs). Relevant information has been extracted from these inspection reports sorted into several categories; including Specific Aging Insights, Preventive Maintenance, Predictive Maintenance and Condition Monitoring, Post Maintenance Testing, Failure Trending, Root Cause Analysis and Usage of Probabilistic Risk Assessment in the Maintenance Process. Specific examples of inspection and monitoring techniques successfully used by utilities to detect degradation due to aging have been identified

    Takeuchi, Yasuhiro

    Disorders in bone and calcium metabolism associated with aging are based on secondary hyperparathyroidism due to impaired intestinal calcium absorption caused by insufficient vitamin D actions and augmented bone resorption due to sex hormone deficiency. Both of them are involved in the development of osteoporosis that increases risk of fractures. Therefore, the most important thing for management of disorders in bone and calcium metabolism associated with aging is to prevent fractures with appropriate drugs for osteoporosis.

    The International Continence Society (ICS) defines overactive bladder (OAB) as an association of symptoms including "urgency, with or without urge incontinence, usually with increased frequency and nocturia". This conditon has been associated with a decrease in quality of life and a higher related risk of overall health condition decrease, and is rising since its prevalence increases with age and the forecast for the world population estimates an increase of those over 65 years old. Aging alone can be considered a major risk factor for developing OAB symptoms that are considered multifactorial and due to body tissue and anatomic changes, lifestyle-associated factors, comorbidities and personal characteristics. The high prevalence of this condition and multiple etiology factors makes of its treatment a challenge-especially in the older population. A major concern over OAB treatment of elderly patients is the risk of cognitive side effects due to the pharmacologic treatment with anticholinergic drugs. First-line treatment for OAB symptoms are the use of pharmacologic therapy with antimuscarinic drugs, which has been proved to be effective in controlling urgency, urge incontinence episodes, incontinence episodes, and nocturia. The impact caused by this condition is significant regarding the economic and human costs associated bringing into attention the need of studying and reviewing this specific population. Conservative Management and Lifestyle Modifications: Behavioral therapy's aims are to reduce urinary frequency and urgency to an accepted level and to increase bladder outlet volume. It consists of actions to teach patients to improve and learn bladder control. Lifestyle modifications are a conjunct of daily activities that can be managed to have the lowest interference on the functioning of the urinary tract. Pharmacologic Therapy: There are various medications with antimuscarinic properties available for the treatment of OAB symptoms. The most commonly used are

    Full text: Karachi Nuclear power Plant (KANUPP), a 137 MWe CANDU plant, was built on a turn-key basis by the Canadian General Electric (CGE) in the late sixties. The plant with a design life of thirty years went into commercial operation in October, 1972. After nearly three decades of operation, KANUPP like all other plants has faced the problem of equipment ageing and obsolescence. KANUPP has been striving hard to combat these problems with the assistance from IAEA, COG and WANO. During early eighties IAEA expert missions were called at KANUPP on various safety issues and on their recommendations various projects such as Safe Operation of KANUPP, Technical Upgradation Project, Balancing, Modernization and Rehabilitation project were initiated to combat equipment ageing and obsolescence. KANUPP has made substantial progress in the implementation of the tasks under these projects and the operating life of the plant is expected to be extended by 15 years. Three IAEA expert missions were invited at KANUPP during 1999-2000 to carry out assessment of the ongoing activities related to plant ageing management. On the basis of their recommendations an ageing Management Programme has been formally established at KANUPP to manage age-related degradation of plant systems, structures and components important to safety and to ensure that the required safety functions are available for the extended life of the plant. Being close to completion of its nominal design life in October 2002, KANUPP has already applied to Pakistan Nuclear Regulatory Authority for renewal of operating license. This paper briefly describes the activities related to ageing management of KANUPP to fulfil the requirement for its continued operation beyond its design life. (author)

  1. Conservative fluid management prevents age-associated ventilator induced mortality.

    Approximately 800 thousand patients require mechanical ventilation in the United States annually with an in-hospital mortality rate of over 30%. The majority of patients requiring mechanical ventilation are over the age of 65 and advanced age is known to increase the severity of ventilator-induced lung injury (VILI) and in-hospital mortality rates. However, the mechanisms which predispose aging ventilator patients to increased mortality rates are not fully understood. Ventilation with conservative fluid management decreases mortality rates in acute respiratory distress patients, but to date there has been no investigation of the effect of conservative fluid management on VILI and ventilator associated mortality rates. We hypothesized that age-associated increases in susceptibility and incidence of pulmonary edema strongly promote age-related increases in ventilator associated mortality. 2month old and 20month old male C57BL6 mice were mechanically ventilated with either high tidal volume (HVT) or low tidal volume (LVT) for up to 4h with either liberal or conservative fluid support. During ventilation, lung compliance, total lung capacity, and hysteresis curves were quantified. Following ventilation, bronchoalveolar lavage fluid was analyzed for total protein content and inflammatory cell infiltration. Wet to dry ratios were used to directly measure edema in excised lungs. Lung histology was performed to quantify alveolar barrier damage/destruction. Age matched non-ventilated mice were used as controls. At 4h, both advanced age and HVT ventilation significantly increased markers of inflammation and injury, degraded pulmonary mechanics, and decreased survival rates. Conservative fluid support significantly diminished pulmonary edema and improved pulmonary mechanics by 1h in advanced age HVT subjects. In 4h ventilations, conservative fluid support significantly diminished pulmonary edema, improved lung mechanics, and resulted in significantly lower mortality rates in

    Full Text Available In the digital age, organizations need to reinvent themselves at a structural level and to become agiler. Digital maturity of human resources management implies a shift from traditional paradigm on workplace towards engagement, learning and development of employees and search for talent. This paper focuses on identifying the major trends and strategies concerning talent management programs and development of digital skills for employees and managers. The study reveals that in an open talent economy, employer brand is very important in recruiting and retention of high potential employees and must be focused on learning & leadership development, mobility, rewards and competency systems. At present, in order to obtain a business value, one of the major challenges that HR needs to face is the development of digital skills for managers and employees.

  3. Aging and intestinal motility: a review of factors that affect intestinal motility in the aged.

    Normal aging is associated with significant changes in the function of most organs and tissues. In this regard, the gastrointestinal tract is no exception. The purpose of this review is to detail the important age-related changes in motor function of the various parts of the gastrointestinal tract and to highlight some of the important motility changes that may occur, either in relation to common age-related disorders, or as a result of certain drugs commonly prescribed in the aged. A major confounding factor in the interpretation of motor phenomena throughout the gastrointestinal tract in this age group is the frequent coexistence of neurological, endocrinological and other disease states, which may be independently associated with dysmotility. Overall, current data are insufficient to implicate normal aging as a cause of dysmotility in the elderly. Normal aging is associated with various changes in gastrointestinal motility, but the clinical significance of such changes remains unclear. More important is the impact of various age-related diseases on gastrointestinal motility in the elderly: for example, long-standing diabetes mellitus may reduce gastric emptying in up to 50% of patients; depression significantly prolongs whole-gut transit time; hypothyroidism may prolong oro-caecal transit time; and chronic renal failure is associated with impaired gastric emptying. In addition, various, frequently used drugs in the elderly cause disordered gastrointestinal motility. These drugs include anticholinergics, especially antidepressants with an anticholinergic effect, opioid analgesics and calcium antagonists.

    Full Text Available Purpose: To provide nursing students knowledge of pain prior, during, and post- surgery, recovery and rehabilitation. Methods: Review articles published during 2005 until 2012 that focused on pain assessment and pain management. The databases used in this study were Medline and CINAHL.Results: Postoperative pains need special approach and care. It needs teach patient how to adapt pain, control pain, monitor result of treatment. Conclusion: Nursing students need to learn how to assess pain using appropriate tools for each age level and in patients with special needs. The students also need to learn about pain management including pharmacology and non-pharmacology means and consider pain as the fifth vital sign. As student nurses learn pain assessment, they should be considerate about culture, and different languages that might happen during practical rotations.

    2004-01-01

    Life extension for nuclear power plants has been studied in the USA for the last six years, largely supported by EPRI, DOE and the USNRC. Though there are diverse opinions for the strategies and priorities of life extension and aging management, one common conclusion has been formulated regarding the need of current maintenance programs having to focus on aging and degradation management. Such program, called 'Maintenance Effectiveness Evaluation and Enhancement' or M3E for short, has been developed to assist plant operators to upgrade and enhance existing programs by integrating aging/degradation management activities for important or critical equipment and components. The key elements of the M3E program consist of the definition and selection of the critical components or commodities to be included in the scope, the survey/inventory of the current programs and their respective action steps, frequencies, corrective measures and extent of coverage, the component/commodity degradation mechanism, sites and severity, safety functions and service environments and lastly, the correlation of degradation/aging with the individual maintenance activities. The degree of correlation provides a measure of effectiveness and the opportunity to identify/specify needed enhancements, abandonment or generation of new maintenance activities. Implementation of the activities can then be prioritized at the option of the plant staff. (author)

    1997-11-01

    This TECDOC is one in a series of reports on the assessment and management of ageing of the major NPP components important to safety. The reports are based on experience and practices of NPP operators, regulators, designers, manufacturers, and technical support organizations and a widely accepted Methodology for the Management of Ageing of NPP Components Important to Safety which was issued by the IAEA in 1992. They have been compiled using contributions from technical experts in typically 10 to 12 countries for each report, a feedback from a September 1994 Technical Committee Meeting attended by 53 technical experts from 21 Member States (who reviewed first drafts in specialized working groups), and review comments from invited specialists

    Generic aging lessons learned (GALL) report is a technical basis document issued by U.S. nuclear regulatory commission (NRC) for guiding the review of license renewal application (LRA) of its domestic nuclear power plants (NPPs). By form of tabulations, GALL report addresses the correlation among materials, environments, aging effects/mechanisms, and aging management programs (AMPs) from the level of specific structures and/or components. Based on literature investigation and analysis, the essential information of GALL report in the aspects of background, development history, content framework, and application was reviewed in this paper, which should be the first time in China and would have reference value for establishment of both the AMPs and the nuclear safety regulations of extending the lifetime of its NPPs.

    New-age technologies are ubiquitous in the lives of adolescents. Recent trends in media use suggest that adolescents are spending more time than ever engaging with technologies, and are able to do so in virtually all settings at any time. Given that new-age technologies are so heavily integrated within the daily life of adolescents, the health risks and benefits they offer must be closely examined. In this systematic review, we present recent literature related to the implications of new-age technologies on adolescent health. A total of 94 articles published since 2006 were collected using PubMed and Google Scholar on the most popular new-age technologies among adolescents: the internet, television, cell phones, and video games. The current body of research highlights several health risks related to these technologies. Nearly all have the potential for addiction, which can result in other symptoms and impair one's daily life. Excessive use can affect several components of health, such as quality of sleep, body composition, and mental well-being, and certain practices (viewing pornography, sexting) can lead to risky sexual behaviors. However, the technologies discussed in the present review also have tremendous potential to promote adolescent health. Pediatricians must educate parents and patients on how to safely use technology to minimize the potentially harmful outcomes.

    Photo-aging is one of the foremost problems caused by generation of reactive oxygen species when skin is exposed on UV irradiation. In view of that, generation of reactive oxygen species intermingle with proteins, DNA, saccharides and fatty acids triggering oxidative mutilation and effects are in the appearance of distressed cell metabolism, morphological and ultra-structural changes, mistreat on the routes and revisions in the demarcation, propagation and skin apoptosis living cells which leads to photo-aging. Plant phenolics are universally found in both edible and inedible plants and have extended substantial interest as photo-protective for human skin due to their antioxidant activities. The objective of this review is to highlight the use of plant phenolics for their antioxidant activities against photo-aging.

    1993-12-31

    Short-rotation intensive-culture (SRIC) of promising tree crops is being evaluated worldwide for the production of methanol, ethanol, and electricity from renewable biomass resources. Planting density and rotation age are fundamental management decisions associated with SRIC energy plantations. Most studies of these variables have been conducted without the benefit of a unifying theory of the effects of growing space and rotation age on individual tree growth and stand level productivity. A modeling procedure based on field trials of Eucalyptus spp. is presented that evaluates the growth potential of a tree in the absence and presence of competition of neighboring trees in a stand. The results of this analysis are useful in clarifying economic implications of different growing space and rotation age decisions that tree plantation managers must make. The procedure is readily applicable to other species under consideration for SRIC plantations at any location.

    In the mid-1990s, New Brunswick Power Nuclear implemented a Management System Process Model at the Point Lepreau Generating Station that provides the basic elements of a knowledge management program. As noted by the IAEA, the challenge facing the nuclear industry now is to make improvements in knowledge management in areas that are more difficult to implement. Two of these areas are: increasing the value of existing knowledge, and converting tacit knowledge to explicit knowledge (knowledge acquisition). This paper describes some practical examples of knowledge management improvements in the Point Lepreau heat transport system ageing management program. (author)

    1994-01-01

    The US Department of Energy, in cooperation with the Electric Power Research Institute and nuclear power plant utilities, has prepared ''Aging Management Guidelines'' (AMGs) for commodity types of equipment (e.g., pumps, electrical switchgear) important to license renewal. For the most part, this is also consistent with the Maintenance Rule, 10 CFR 50.65 (1991). AMGs concentrate on technical, (not licensing) issues and are directed toward systems engineers and plant maintenance staff. AMGs include a detailed summary of operating history, stressors, aging mechanisms, and various types of maintenance practices that can be combined to create effective programs that manage aging. All aging mechanisms were addressed; no attempt was made to limit the evaluation to aging mechanisms ''unique to license renewal,'' as defined in the License Renewal Rule, 10 CFR 54 (1991). The first AMG on Electrical Switchgear was published in July 1993. Six (6) additional AMGs will be published by the first quarter of calendar year 1994. It is anticipated that two more AMGs will be started in 1994. The seven ongoing AMG topics are as follows: (1) battery chargers, inverters and uninterruptible power supplies; (2) batteries, stationary; (3) heat exchangers; (4) motor control centers; (5) pumps; (6) switchgear, electric; (7) transformers, power and distribution. In Section 7, industry feedback regarding AMGs is discussed. Overall, the response has been very positive

    This paper presents EDF practice about concrete structure ageing management, from the mechanisms analysis to the formal procedure which allows the French company to increase 900 MWe NPP lifetime until 40 years; it will also introduce its action plan for 60 years lifetime extension. This practice is based on a methodology which identifies every ageing mechanism; both plants feedback and state of the art are screened and conclusions are drawn up into an "ageing analysis data sheet". That leads at first to a collection of 57 data sheets which give the mechanism identification, the components that are concerned and an analysis grid which is designed to assess the safety risk. This analysis screens the reference documents describing the mechanism, the design lifetime hypotheses, the associated regulation or codification, the feedback experiences, the accessibility, the maintenance actions, the repair possibility and so one. This analysis has to lead to a conclusion about the risk taking into account monitoring and maintenance. If the data sheet conclusion is not clear enough, then a more detailed report is launched. The technical document which is needed, is a formal detailed report which summarizes every theoretical knowledge and monitoring data: its objective is to propose a solution for ageing management: this solution can include more inspections or specific research development, or additional maintenance. After a first stage on the 900 MWe units, only two generic ageing management detailed reports have been needed for the civil engineering part: one about reactor building containment, and one about other structures which focuses on concrete inflating reactions. The second stage consists on deriving this generic analysis (ageing mechanism and detailed reports) to every plant where a complete ageing report is required (one report for all equipments and structures of the plant, but specific for each reactor). This ageing management is a continuous process because the

    As the elderly population grows, so do the clinical and socioeconomic burdens of nonhealing cutaneous wounds, the majority of which are seen among persons over 60 years of age. Human studies on how aging effects wound healing will always be the gold standard, but studies have ethical and practical hurdles. Choosing an animal model is dictated by costs and animal lifespan that preclude large animal use. Here, we review the current literature on how aging effects cutaneous wound healing in small animal models and, when possible, compare healing across studies. Using a literature search of MEDLINE/PubMed databases, studies were limited to those that utilized full-thickness wounds and compared the wound-healing parameters of wound closure, reepithelialization, granulation tissue fill, and tensile strength between young and aged cohorts. Overall, wound closure, reepithelialization, and granulation tissue fill were delayed or decreased with aging across different strains of mice and rats. Aging in mice was associated with lower tensile strength early in the wound healing process, but greater tensile strength later in the wound healing process. Similarly, aging in rats was associated with lower tensile strength early in the wound healing process, but no significant tensile strength difference between young and old rats later in healing wounds. From studies in New Zealand White rabbits, we found that reepithelialization and granulation tissue fill were delayed or decreased overall with aging. While similarities and differences in key wound healing parameters were noted between different strains and species, the comparability across the studies was highly questionable, highlighted by wide variability in experimental design and reporting. In future studies, standardized experimental design and reporting would help to establish comparable study groups, and advance the overall knowledge base, facilitating the translatability of animal data to the human clinical condition.

    Introduction Oral Lichen Planus (OLP) is a chronic inflammatory, T-cell-mediated autoimmune oral mucosal disease with unclear aetiology. The clinical management of OLP poses considerable difficulties to the oral physician. Aim The aim was to assess the efficacy of any form of intervention used to medically manage OLP. Materials and Methods We searched and analysed the following databases (from January 1990 to December 2014):- Cochrane Oral Health Group Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. All Randomised Controlled Trials (RCTs) for the medical management of OLP which compared active treatment with placebo or between active treatments were considered in this systematic review. Participants of any age, gender or race having symptomatic OLP (including mixed forms), unconnected to any identifiable cause (e.g. lichenoid drug reactions) and confirmed by histopathology have been included. Interventions of all types, including topical treatments or systemic drugs of variable dosage, duration & frequency of delivery have been considered. All the trials identified were appraised by five review authors and the data for all the trials were synthesised using specifically designed data extraction form. Binary data has been presented as risk ratios (RR) with 95% confidence intervals (CI) and continuous data as mean differences (MD) with 95% CIs. Results A total of 35 RCTs were included in this systematic review on medical management of OLP. No strong evidence suggesting superiority of any specific intervention in reducing pain and clinical signs of OLP were shown by the RCTs included here. Conclusion Future RCTs on a larger scale, adopting standardized outcome assessing parameters should be considered. PMID:27042598

    Development of an aging management plan (AMP) is a crucial contributor to maintaining the reactor safety and controlling the risk of degradation of the concrete reactor building of a nuclear power plant. The design, operation and utilization of a research reactor (RR) fundamentally differ from those of power reactors. The AMP should nonetheless be present on account of radioactive materials and radiation risks involved. This is mainly because the RR is deemed to be used as an experiment itself or to conduct separate experiments during its operation. The AMP aims to determine the requisites for specific structural concrete components of the reactor building that entail regular inspections and maintenance to ensure safe and reliable operation of the plant. The safety of a RR necessitates the provision which is made in its design to facilitate aging management. Aging management of RR's structures is one of the vital factors to safety, to ensure continued adequacy of the safety level, reliable operation of the reactor, and compliance with the operational limits and conditions.Moreover, engineering systems should be qualified to meet the functional requirements for which they were designed with aging and environmental conditions for all situations and at all times taken into account. This study aims to present an integrated methodology for the application of an AMP for the concrete of the reactor building of a typical RR. For the purpose of safety analysis, geometry and ambient conditions were taken from a 5 MW pool-type, light-water moderated, heterogeneous, solid fuel RR in which the water is also used for cooling and shielding (Fig. 1). The reactor core is immersed in either section of a two-section concrete pool filled with water. This paper makes available background information regarding the document and the strategy developed to manage potential degradation of the reactor building concrete as well as specific programs and preventive and corrective

    2009-12-01

    Neuroeconomics refers to a combination of paradigms derived from neuroscience, psychology, and economics for the study of decision making and is an area that has received considerable scientific attention in the recent literature. Using realistic laboratory tasks, researchers seek to study the neurocognitive processes underlying economic decision making and outcome-based decision learning, as well as individual differences in these processes and the social and affective factors that modulate them. To this point, one question has remained largely unanswered: What happens to decision-making processes and their neural substrates during aging? After all, aging is associated with neurocognitive change, which may affect outcome-based decision making. In our study, we use the subjective expected utility model-a well-established decision-making model in economics-as a descriptive framework. After a short survey of the brain areas and neurotransmitter systems associated with outcome-based decision making-and of the effects of aging thereon-we review a number of decision-making studies. Their general data pattern indicates that the decision-making process is changed by age: The elderly perform less efficiently than younger participants, as demonstrated, for instance, by the smaller total rewards that the elderly acquire in lab tasks. These findings are accounted for in terms of age-related deficiencies in the probability and value parameters of the subjective expected utility model. Finally, we discuss some implications and suggestions for future research.

    Aging is an agglomerate of biological long-lasting processes that result being inevitable. Main actors in this scenario are both long-term inflammation and oxidative stress. It has been proved that oxidative stress induce alteration in proteins and this fact itself is critically important in the pathophysiological mechanisms leading to diseases typical of aging. Among reactive species, chlorine ones such as hypochlorous acid (HOCl) are cytotoxic oxidants produced by activated neutrophils during chronic inflammation processes. HOCl can also cause damages by reacting with biological molecules. HOCl is generated by myeloperoxidase (MPO) and augmented serum levels of MPO have been described in acute and chronic inflammatory conditions in cardiovascular patients and has been implicated in many inflammatory diseases such as atherosclerosis, neurodegenerative conditions, and some cancers. Due to these data, we decided to conduct an up-to-date review evaluating chlorinative stress effects on every age-related disease linked; potential anti-oxidant countermeasures were also assessed. Results obtained associated HOCl generation to the aging processes and confirmed its connection with diseases like neurodegenerative and cardiovascular pathologies, atherosclerosis and cancer; chlorination was mainly linked to diseases where molecular (protein) alteration constitute the major suspected cause: i.e. inflammation, tissue lesions, DNA damages, apoptosis and oxidative stress itself. According data collected, a healthy lifestyle together with some dietary suggestion and/or the administration of nutracetical antioxidant integrators could balance the effects of chlorinative stress and, in some cases, slow down or prevent the onset of age-releated diseases.

    Recent progress in the description of glassy relaxation and aging are reviewed for the wide class of network-forming materials such as GeO2, Ge x Se1-x , silicates (SiO2-Na2O) or borates (B2O3-Li2O), all of which have an important usefulness in domestic, geological or optoelectronic applications. A brief introduction of the glass transition phenomenology is given, together with the salient features that are revealed both from theory and experiments. Standard experimental methods used for the characterization of the slowing down of the dynamics are reviewed. We then discuss the important role played by aspects of network topology and rigidity for the understanding of the relaxation of the glass transition, while also permitting analytical predictions of glass properties from simple and insightful models based on the network structure. We also emphasize the great utility of computer simulations which probe the dynamics at the molecular level, and permit the calculation of various structure-related functions in connection with glassy relaxation and the physics of aging which reveal the non-equilibrium nature of glasses. We discuss the notion of spatial variations of structure which leads to the concept of 'dynamic heterogeneities', and recent results in relation to this important topic for network glasses are also reviewed.

    Pressure to improve plant efficiency and maximize safety and the increasing age of existing NPPs are forcing the global nuclear power industry to confront the challenges of aging - caused by stressors such as temperature, humidity, radiation, electricity, and vibration - in key instrument and control (I and C) components like pressure transmitters, temperature sensors, neutron detectors, and cables. Traditional aging management methods, such as equipment replacement, required the process to be shut down. Recent aging management technologies, collectively known as online monitoring (OLM), enable plants to monitor the condition and aging of their installed I and C while the plant is operating. Developed through R and D initiatives worldwide, such OLM techniques include low- and high-frequency methods that use existing sensors, such as noise analysis; methods based on test or diagnostic sensors, such as for vibration-measuring accelerometers; and methods, such as the power interrupt (PI) test, based on active measurements made by injecting a test signal into the component under test. A review of these aging management methods, their effectiveness, and their interrelation provides a foundation for understanding the next stage in the evolution of OLM: truly integrated hybrid OLM systems capable of robust condition monitoring in both novel and familiar operating conditions.

    Background Visual impairment in elderly people is a considerable health problem that significantly affects quality of life of millions worldwide. The magnitude of this issue is becoming more evident with an aging population and an increasing number of older individuals. Objective The objective of this article was to review the clinical and pathological aspects of age-related macular degeneration (AMD), diagnostic tools, and therapeutic modalities presently available or underway for both atrophic and wet forms of the disease. Methods An online review of the PubMed database was performed, searching for the key words. The search was limited to articles published since 1980 to date. Results Several risk factors have been linked to AMD, such as age (>60 years), lifestyle (smoking and diet), and family history. Although the pathogenesis of AMD remains unclear, genetic factors have been implicated in the condition. Treatment for atrophic AMD is mainly close observation, coupled with nutritional supplements such as zinc and antioxidants, whereas treatment of wet AMD is based on targeting choroidal neovascular membranes. Conclusion Identification of modifiable risk factors would improve the possibilities of preventing the progression of AMD. The role of anti-vascular endothelial growth factor (anti-VEGF) agents has transformed the therapeutic approach of the potentially blinding disease “wet AMD” into a more favorable outcome.

    2014-01-01

    In an ageing nuclear power station there are many challenges associated with implementing and refining an asset management program. Ageing nuclear power stations are faced with the formidable task of replacing and refurbishing major Structures, Systems, and Components (SSCs) in a managed and cost-effective way. This paper provides a brief background on equipment reliability and asset management, covers Bruce Power's methodology for implementing this complex and all-encompassing program, and describes one of the key challenges faced by Bruce Power and the industry. The effective scoping and identification of critical components is an on-going challenge which can affect the integrity of many processes built upon it. This is a fundamental building block to nearly all processes at Bruce Power and one that is at the centre of many improvement initiatives and projects. The consequences from lacking this baseline data, or worse relying upon incorrect data, can permeate the asset management process and hinder the organization's ability to assess risk properly and take the necessary steps to mitigate this risk in the short and long term.

    2014-01-01

    Prolonging working careers by increasing the statutory age for retirement has become compulsory in most Western societies in order to tackle the shrinking of the labour force, preserve economic productivity, foster knowledge transfer and reduce the risks of financial imbalances in social security systems. This imperative currently results in working careers that already exceed 40 years and come to an end after the age of 65 (e.g. in Italy). Over the next few decades, both career length and retirement age are expected to rise. Thus, creating more inclusive workplaces by increasing their quality is the precondition of a win-win situation for both employers and employees, regardless of age. A request for support in the development of sustainable careers from both private and public labour organisations has led to innovating the mainstream methodologies and research tools in the field of age management. Based on the key elements of the mainstream "work ability concept" - i.e. health, competencies, motivation and work organisation - the Quality of Ageing at Work questionnaire (QAW-q), developed by a team from the WWELL Research Centre, broadens its perspective by surveying elements bridging intra-organisational dimensions and which affect employees' conditions and external socio-institutional constraints: i.e. work-life balance, economic stability, professional identity and relationships in the workplace. The QAW-q is designed to analyse the influence of the different meanings of age (chronological age, seniority within the company and in the labour market) and correlate them with the different dimensions at individual and organisational levels; all these dimensions are weighted by the effect exerted by the passage of time. The results of the QAW-q survey, taken by employees of both private and public companies, serve as a basis for the implementation of measures addressing all the relevant dimensions of the human resource management cycle.

  7. Aging management of light water reactor concrete containments

    International Nuclear Information System (INIS)

    Shah, V.N.; Hookhman, C.J.

    1994-01-01

    This paper evaluates aging of light water reactor concrete containments and identifies three degradation mechanisms that have potential to cause widespread aging damage after years of satisfactory experience: alkali-silica reaction, corrosion of reinforcing steel, and sulfate attack. The evaluation is based on a comprehensive review of the relevant technical literature. Low-alkali cement and slow-reacting aggregates selected according to ASTM requirements cause deleterious alkali-silica reactions. Low concentrations of chloride ions can initiate corrosion of the reinforcing steel if the hydroxyl ions are sufficiently reduced by carbonation, leaching, or magnesium sulfate attack. Magnesium sulfate attack on concrete can cause loss of strength and cementitious properties after long exposure. Techniques to detect and mitigate these long-term aging effects are discussed

    Nondestructive evaluation of material damage can contribute to continued safe, reliable, and economical operation of nuclear power plants through their current and renewed license period. The aging mechanisms active in the major light water reactor components are radiation embrittlement, thermal aging, stress corrosion cracking, flow-accelerated corrosion, and fatigue, which reduce fracture toughness, structural strength, or fatigue resistance of the components and challenge structural integrity of the pressure boundary. This paper reviews four nondestructive evaluation methods with the potential for in situ assessment of damage caused by these mechanisms: stress-strain microprobe for determining mechanical properties of reactor pressure vessel and cast stainless materials, magnetic methods for estimating thermal aging damage in cast stainless steel, positron annihilation measurements for estimating early fatigue damage in reactor coolant system piping, and ultrasonic guided wave technique for detecting cracks and wall thinning in tubes and pipes and corrosion damage to embedded portion of metal containments

    As more data gathering, analysis, and tracking tasks are outsourced the need for multiple contractors and military personnel to input, update, access, store, and track Mormation is becoming critical to efficient functioning and managing of environmental projects and programs at military installations. This paper presents two case studies detailing the way two organizations--the Rocky Mountain Arsenal (RMA) in Colorado, and the 611th Air Support Group (611 ASG) in Alaska--are managing complex data using web-based technology. RMA is involved in one of the largest environmental cleanup programs in the Department of Defense. As such, large volumes of environmental data and documents must be generates stored, and tracked. Often these documents are prepared by multiple contractors and are reviewed by several parties or groups. To manage environmental information and to ensure that it meets compliance requirements more efficiently, RMA has developed an electronic document tracking and distribution system. This system allows access to up-to-date information, including a detailed review of all pertinent regulatory and other requirements at RMA. The dynamic system includes milestones, review deadlines, submission deadlines, and other requirements for managing the environmental program. The 611 ASG manages more than 30 remote installations in Alaska, many of which are operated by contractor personnel. These installations contain hundreds of buildings that are constantly being modified because of exposure to harsh arctic climates; some of them have been determined to be eligible for the National Register of Historic Places. To meet regulatory requirements for cultural resources management as well as engineering requirements for upkeep of buildings, a database was developed to store and analyze building data. The database has a web-based interface that allows anyone with the correct access codes to input new data, modify existing data, or query the database using a number of

    The second research reactor of Egypt, ETRR-II, is an open pool type multi-purpose reactor of 22 MW that has been in operation since 1998. The main purposes of ETRR-II are the production of radioisotopes, personnel training, research and development. Ageing management of ETRR-II is based on the maintenance programme. This programme was planned to have a proactive maintenance strategy that mainly depends on adequate preventive and predictive maintenance. Screening of SSCs is based on safety classes, needs and quality levels. The operation condition and maintenance history are the basis to assess the level of degradation. The ultimate aim of the maintenance team is to perform adequate maintenance work only when it is really necessary. The objectives of the ageing management based maintenance are to maintain and improve equipment availability, confirm compliance with operational limits and conditions, and detect and correct any abnormal condition that might affect reactor safety. The programme also helps to detect trends in ageing so that a plan for mitigating ageing effects can be prepared and implemented. Reactor service conditions are monitored through many parameters and conditions such as conductivity and pH of coolant water, water radiochemical analysis, thermal and hydraulic parameters, a leak detection system, corrosion rate of piping, vibration level of rotating equipment and control rod drop time.

    Due to life-enhancing effects of antiretroviral therapy, HIV-positive persons have the potential for long life comparable to their uninfected peers. Older women (age 50+) living with HIV (OWLH) are often an under-recognized aging group. We conducted a systematic review to examine psychosocial factors that impact how OWLH live, cope, and age with HIV. Initial key word search yielded 1527 records, and 21 studies met our inclusion criteria of original quantitative or qualitative research published between 2013 and 2016 with results specific to OWLH. These focused on health care and self-management, sexual health and risk, stigma, loneliness, mental health (depression, substance use), and protective factors (coping, social support, well-being). Due to the scarcity of studies on each topic and inconclusive findings, no clear patterns of results emerged. As the number of OWLH continues to grow, more research, including longitudinal studies, is needed to fully characterize the psychosocial factors that impact aging with HIV.

    Full Text Available Uterine leiomyomata are the most common benign tumors of the gynecologic tract impacting up to 80% of women by 50 years of age. It is well established that these tumors are the leading cause for hysterectomy with an estimated total financial burden greater than $30 billion per year in the United States. However, for the woman who desires future fertility or is a poor surgical candidate, definitive management with hysterectomy is not an optimal management plan. Typical gynecologic symptoms of leiomyoma include infertility, abnormal uterine bleeding (AUB/heavy menstrual bleeding (HMB and/or intermenstrual bleeding (IMB with resulting iron-deficiency anemia, pelvic pressure and pain, urinary incontinence, and dysmenorrhea. The morbidity caused by these tumors is directly attributable to increases in tumor burden. Interestingly, leiomyoma cells within a tumor do not rapidly proliferate, but rather the increase in tumor size is secondary to production of an excessive, stable, and aberrant extracellular matrix (ECM made of disorganized collagens and proteoglycans. As a result, medical management should induce leiomyoma cells toward dissolution of the extracellular matrix, as well as halting or inhibiting cellular proliferation. Herein, we review the current literature regarding the medical management of uterine leiomyoma.

  15. Spirituality, religiosity, aging and health in global perspective: A review

    Full Text Available Persistent population aging worldwide is focusing attention on modifiable factors that can improve later life health. There is evidence that religiosity and spirituality are among such factors. Older people tend to have high rates of involvement in religious and/or spiritual endeavors and it is possible that population aging will be associated with increasing prevalence of religious and spiritual activity worldwide. Despite increasing research on religiosity, spirituality and health among older persons, population aging worldwide suggests the need for a globally integrated approach. As a step toward this, we review a subset of the literature on the impact of religiosity and spirituality on health in later life. We find that much of this has looked at the relationship between religiosity/spirituality and longevity as well as physical and mental health. Mechanisms include social support, health behaviors, stress and psychosocial factors. We identify a number of gaps in current knowledge. Many previous studies have taken place in the U.S. and Europe. Much data is cross-sectional, limiting ability to make causal inference. Religiosity and spirituality can be difficult to define and distinguish and the two concepts are often considered together, though on balance religiosity has received more attention than spirituality. The latter may however be equally important. Although there is evidence that religiosity is associated with longer life and better physical and mental health, these outcomes have been investigated separately rather than together such as in measures of health expectancy. In conclusion, there is a need for a unified and nuanced approach to understanding how religiosity and spirituality impact on health and longevity within a context of global aging, in particular whether they result in longer healthy life rather than just longer life.

    Fluid intake, especially water, is essential for human life and also necessary for physical and mental function. The present study aimed to assess beverage consumption across age groups. A systematic review was conducted. Original research in English language publications and available studies (or abstracts in English) from 2000 to 2013 was searched for by using the medical subheading (MeSH) terms: ('beverage' OR 'fluid' [Major]) AND ('consumption' [Mesh] OR 'drinking' [Mesh] OR 'intake' [Mesh]) AND ('child' [Mesh] OR 'adolescent' [Mesh] OR 'adult' [Mesh]). Article selection was restricted to those papers covering healthy populations of all age groups in a nationwide sample, or from a representative sample of the population of a city or cities, which examined the trends or patterns of beverage intake and the determinants of beverage intake. Sixty-five studies were identified with respect to beverage consumption across age groups. The papers were screened by thoroughly reading titles or abstracts. Full-text articles were assessed by three investigators. Total beverage intake varied between 0.6 and 3.5 L day(-1) among all age groups (males more than females). Plain water contributed up to 58%, 75% and 80% of the total beverage intake in children, adolescents and adults, respectively. Milk consumption was higher among children; consumption of soft drinks was higher among adolescents; and the consumption of tea, coffee and alcoholic beverages was higher among adults. Plain water is the main water source for all age groups and the consumption of other beverages varies according to age. © 2014 The British Dietetic Association Ltd.

    Yankee Atomic Electric Company has developed the component degradation assessment tool (CoDAT), an expert system, that aids in handling and evaluating the large amounts of data required to support the license renewal process for nuclear power station fluid systems. In 1990, CoDAT evaluated the Yankee Nuclear Power Station fluid systems for age-related degradation. Its results are now being used to help focus the plant's maintenance programs and manage the expected degradation. CoDAT uses 'If-Then' rules, developed from industry codes, standards and publications, to determine the potential for 19 age-related degradation mechanisms. Other nuclear utilities pursuing the license renewal option also could use CoDAT. (author)

    Rejuvenative procedures of the face are increasing in numbers, and a plethora of different therapeutic options are available today. Every procedure should aim for the patient's safety first and then for natural and long-lasting results. The face is one of the most complex regions in the human body and research continuously reveals new insights into the complex interplay of the different participating structures. Bone, ligaments, muscles, fat, and skin are the key players in the layered arrangement of the face.Aging occurs in all involved facial structures but the onset and the speed of age-related changes differ between each specific structure, between each individual, and between different ethnic groups. Therefore, knowledge of age-related anatomy is crucial for a physician's work when trying to restore a youthful face.This review focuses on the current understanding of the anatomy of the human face and tries to elucidate the morphological changes during aging of bone, ligaments, muscles, and fat, and their role in rejuvenative procedures.

    1989-01-01

    The Nuclear Regulatory Commission's Office of Nuclear Regulatory Research is sponsoring this effort to study maintenance as it relates to aging, under the Nuclear Plant Aging Research (NPAR). Maintenance is the primary means of combating and correcting the effects of aging degradation at nuclear power plants. Maintenance effectiveness directly affects the safety of nuclear power plants. Several recent plant events have shown that improper maintenance or a lack of maintenance can be a significant contributory cause of plant incidents (e.g., transients at Rancho Seco and Davis Besse, and the Salem anticipated transient without scram event). In these, and other events, safety related plant equipment functions have been impaired by poor maintenance practices or a lack of maintenance on the specific equipment or in ancillary equipment that affects the ability of the safety related equipment to function. In some cases, the ancillary equipment has been nonsafety-related equipment, or balance-of-plant equipment that has not received adequate maintenance attention. In addition to the potential for causing safety significant plant transients, poor or lacking maintenance may allow the licensing basis of the plant to be eroded without detection. In some cases, time-related aging degradation of equipment that has not been detected, corrected or managed by the maintenance program has been a significant contributory factor. The NPAR program has developed significant information on aging degradation, detection, mitigation, and correction practices for safety-significant structures, systems and components that can be factored into maintenance programs and their effectiveness

    To undertake a systematic critical appraisal of guidelines to provide a summary of recommendations for the physical management of osteoarthritis (OA). The Cochrane Library, MEDLINE, CINAHL, SPORTDiscus with Full Text, Scopus, ScienceDirect, PEDro, and Google Scholar databases were searched (2000-2013) to identify all guidelines, protocols, and recommendations for the management or treatment of OA. In addition, Internet searches of all relevant arthritis organizations were undertaken. All searches were performed between July 2012 and end of April 2013. Guidelines that included only pharmacological, injection therapy, or surgical interventions were excluded. Guidelines published only in English were retrieved. OA guidelines developed from evidence-based research, consensus, and/or expert opinion were retrieved. There were no restrictions on severity or site of OA, sex, or age. Nineteen guidelines were identified for evaluation. The quality of all guidelines was critically appraised using the Appraisal of Guidelines for REsearch and Evaluation II instrument. Each guideline was independently reviewed. All relevant recommendations for the physical management of OA were synthesized, graded, and ranked according to available evidence. Seventeen guidelines with recommendations on the physical management of OA met the inclusion criteria and underwent a full critical appraisal. There were variations in the interventions, levels of evidence, and strength of recommendations across the guidelines. Forty different interventions were identified. Recommendations were graded from "strongly recommended" to "unsupported." Exercise and education were found to be strongly recommended by most guidelines. Exercise and education were key recommendations supporting the importance of rehabilitation in the physical management of OA. This critical appraisal can assist health care providers who are involved in the management of people with OA. Copyright © 2014 American Congress of

    Traumatic spondylolisthesis of the axis, is a common cervical spine fracture; however, to date there is limited data available to guide the treatment of these injuries. The purpose of this review is to provide an evidence-based analysis of the literature and clinical outcomes associated with the surgical and nonsurgical management of hangman's fractures. A systematic literature search was conducted using PubMed (MEDLINE) and Scopus (EMBASE, MEDLINE, COMPENDEX) for all articles describing the treatment of hangman's fractures in 2 or more patients. Risk of nonunion, mortality, complications, and treatment failure (defined as the need for surgery in the nonsurgically managed patients and the need for revision surgery for any reason in the surgically managed patients) was compared for operative and nonoperative treatment methods using a generalized linear mixed model and odds ratio analysis. Overall, 25 studies met the inclusion criteria and were included in our quantitative analysis. Bony union was the principal outcome measure used to assess successful treatment. All studies included documented fracture union and were included in statistical analyses. The overall union rate for 131 fractures treated nonsurgically was 94.14% [95% confidence interval (CI), 76.15-98.78]. The overall union rate for 417 fractures treated surgically was 99.35% (95% CI, 96.81-99.87). Chance of nonunion was lower in those patients treated surgically (odds ratio, 0.12; 95% CI, 0.02-0.71). There was not a significant difference in mortality between patients treated surgically (0.16%; 95% CI, 0.01%-2.89%) and nonsurgically (1.04%; 95% CI, 0.08%-11.4%) (odds ratio, 0.15; 95% CI, 0.01-2.11). Treatment failure was less likely in the surgical treatment group (0.12%; 95% CI, 0.01%-2.45%) than the nonsurgical treatment group (0.71%; 95% CI, 0.28%-15.75%) (odds ratio 0.07; 95% CI, 0.01-0.56). Hangman's fractures are common injuries, and surgical treatment leads to an increase in the rate of

  6. Young age as a modifying factor in sports concussion management: what is the evidence?

    Foley, Cassidy; Gregory, Andrew; Solomon, Gary

    2014-01-01

    In 2008, the Concussion in Sport Group (CISG) published its third consensus statement and introduced 10 'modifying' factors that were presumed clinically to influence the investigation and management of concussions in sports. Young age was listed as one of the modifying factors. In some cases, these modifiers were thought to be predictive of prolonged or persistent symptoms. These same modifying factors were retained in the fourth iteration of the CISG consensus statement (2013), although mention was made of possible limitations of their efficacy. The CISG statements provided several empirical references regarding young age as a modifying factor. We reviewed the published sports concussion literature with the purpose of determining empirical studies that support or refute the inclusion of young age as a modifier of concussive injury in sports. We performed a systematic review of the PubMed database utilizing the keywords concussion, sports, mild traumatic brain injury, youth, adolescents, and children. English language studies were extracted by the authors and summarized for review. Multiple empirical studies were found indicating that younger athletes may take longer to recover from a sports-related concussion (SRC) than their older peers. However, studies did not indicate that younger athletes were at more risk for prolonged recovery (>4 wk). Empirical evidence supports the inclusion of young age as a modifying factor in sports concussion. However, the difference in recovery time seems relatively small (a few days) and young age does not predict prolonged recovery (>4 wk). The findings support the inclusion of young age as a specific modifier in the treatment of SRC and have implications for the clinical management of this common injury.

    The deregulation of the power generation industry has resulted in increased competitive pressure and is forcing operators to improve plant operating economy while maintaining high levels of plant safety. A key factor to meet this challenge is to apply a comprehensive plant life management (PLIM) approach which addresses all relevant ageing and degradation mechanisms regarding the safety concept, plant components and documentation, plant personnel, consumables, operations management system and administrative controls. For this reason, Framatome ANP has developed an integrated PLIM concept focussing on the safety concept, plant components and documentation. Representative examples for plant wide analyses are described in the following. The results of the analyses support the plant owner for taking the strategic decisions, involved in plant life extension (PLEX). (orig.)

  9. Introducing Systematic Aging Management for Interim Storage Facilities in Germany

    International Nuclear Information System (INIS)

    Spieth-Achtnich, Angelika; Schmidt, Gerhard

    2014-01-01

    In Germany twelve at-reactor and three central (away from reactor) dry storage facilities are in operation, where the fuel is stored in combined transport-and-storage casks. The safety of the storage casks and facilities has been approved and is licensed for up to 40 years operating time. If the availability of a final disposal facility for the stored wastes (spent fuel and high-level wastes from reprocessing) will be further delayed the renewal of the licenses can become necessary in future. Since 2001 Germany had a regulatory guideline for at-reactor dry interim storage of spent fuel. In this guideline some elements of ageing were implemented, but no systematic approach was made for a state-of-the-art ageing management. Currently the guideline is updated to include all kind of storage facilities (central storages as well) and all kinds of high level waste (also waste from reprocessing). Draft versions of the update are under discussion. In these drafts a systematic ageing management is seen as an instrument to upgrade the available technical knowledge base for possible later regulatory decisions, should it be necessary to prolong storage periods to beyond the currently approved limits. It is further recognized as an instrument to prevent from possible and currently unrecognized ageing mechanisms. The generation of information on ageing can be an important basis for the necessary safety-relevant verifications for long term storage. For the first time, the demands for a systematic monitoring of ageing processes for all safety-related components of the storage system are described. In addition, for inaccessible container components such as the seal system, the neutron shielding, the baskets and the waste inventory, the development of a monitoring program is recommended. The working draft to the revised guideline also contains recommendations on non-technical ageing issues such as the long-term preservation of knowledge, long term personnel planning and long term

    2015-06-01

    Improvement of medication adherence in the school-age child can lead to improvement in quality of life, decreased morbidity, and a potential decreased risk of deferred academic, social, and emotional development. The objective of this article is to review barriers to asthma medication adherence and identify evidence-based techniques that improve medication management of the asthmatic child 5 to 12 years of age. A literature review was performed and articles were obtained through database searches within Medline, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and PubMed. Research indicates that barriers to the adherence of medication regimens required for asthmatic children include poor understanding of the medication regimen, substandard education on symptom recognition and environmental triggers, rejection of the diagnosis, and a lack of support or understanding within the community. Researched techniques aimed to improve medication management in 5- to 12-year-olds include: computer-based education; workshops for parents, teachers, and children; incorporation of asthma education into classroom lessons; use of case managers; the introduction of a nurse practitioner in the school to provide care, including medication prescriptions for the asthmatic child; and assessment and evaluation of environmental and emotional triggers in the home and school. Collaboration of current data may help lead to a successful interventional model that can improve asthma management in this population. © The Author(s) 2014.

    The HANARO, an open-tank-in-pool type research reactor of 30MWth power in Korea, has operated for 8 years since its initial criticality in February of 1995. The reactor power has been gradually increased to 24 MWth through the service period. Therefore the reactor age is very young from the viewpoint of the ageing effect on the reactor structure and components by neutron irradiation considering the expected reactor lifetime. But, we have a few programs to manage the ageing from the aspect of design lifetime of reactor components. This paper summarizes the overall progress and plan for the ageing management for the reactor components including lifetime extension and design improvement, remote measurements and in-service inspections. The shutoff units and control absorber units have aged more rapidly than other structures or components because the number of rod drop cycles was higher than expected at the design stage. The system commissioning tests, periodic performance tests, and weekly operation for the stable supply of medical radioisotopes overriding the normal cycle operation have contributed to the high frequency of rod drop. Therefore, we have instituted a program to extend the lifetime of the shutoff units and the control absorber units. This program includes an endurance test to verify the performance for the extended number of drops and the management of shutdown methods to minimize the drop cycles for both the shutoff units and the control absorber units. The program also includes the design improvement of the damper mechanism of the control absorber units to reduce the impact force caused by rod drop. The inner shell of the reflector vessel surrounding the core is the most critical part from the viewpoint of neutron irradiation. The periodic measurement of the dimensional change in the vertical straightness of the inner shell is considered as one of the in-service inspections. We developed a few tools and verified the performance to measure the

    A plant`s maintenance program is the principal vehicle through which age-related degradation is managed. From 1988 to 1991, the NRC evaluated the maintenance program of every nuclear power plant in the United States. Forty-four out of a total of 67 of the reports issued on these in-depth team inspections were reviewed for insights into the strengths and weaknesses of the programs as related to the need to understand and manage the effects of aging on nuclear plant systems, structures, and components. Relevant information was extracted from these inspection reports and sorted into several categories, including Specific Aging Insights, Preventive Maintenance, Predictive Maintenance and Condition Monitoring, Post Maintenance Testing, Failure Trending, Root Cause Analysis and Usage of Probabilistic Risk Assessment in the Maintenance Process. Specific examples of inspection and monitoring techniques successfully used by utilities to detect degradation due to aging have been identified. The information also was sorted according to systems and components, including: Auxiliary Feedwater, Main Feedwater, High Pressure Injection for both BWRs and PWRs, Service Water, Instrument Air, and Emergency Diesel Generator Air Start Systems, and Emergency Diesel Generators Air Start Systems, emergency diesel generators, electrical components such as switchgear, breakers, relays, and motor control centers, motor operated valves and check valves. This information was compared to insights gained from the Nuclear Plant Aging Research (NPAR) Program. Attributes of plant maintenance programs where the NRC inspectors felt that improvement was needed to properly address the aging issue also are discussed.

    Full Text Available Phytotherapy has long been a source of medicinal products and over the years there have been many attempts to use herbal medicines for the treatment of diabetes. Several medicinal plants and their preparations have been demonstrated to act at key points of glucidic metabolism. The most common mechanisms of action found include the inhibition of α-glucosidase and of AGE formation, the increase of GLUT-4 and PPARs expression and antioxidant activity. Despite the large amount of literature available, the actual clinical effectiveness of medicinal plants in controlling diabetes-related symptoms remains controversial and there is a crucial need for stronger evidence-based data. In this review, an overview of the medicinal plants, which use in the management of diabetes is supported by authoritative monographs, is provided. References to some species which are currently under increasing clinical investigation are also reported.

    Lindenmayer, Jean-Pierre; Kaur, Amandeep

    2016-04-01

    Schizoaffective disorder (SAD) is an incapacitating illness that presents clinicians with challenges in terms of both its diagnosis and its psychopharmacological management. Most studies conducted on the psychopharmacological treatment of SAD also include patients with schizophrenia or other psychotic illnesses, thereby providing an unspecific view to the clinician as to the best way of treating patients with SAD. The objective of this article is to review studies on evidence-based treatment of patients with SAD. We conducted a systematic literature search in MEDLINE/PubMed for full-text studies in the English language using the terms 'Schizoaffective and treatment' or 'antipsychotic schizoaffective'. Our review found relatively few studies with either an active comparator or placebo that examined the efficacy of antipsychotics for patients with SAD without an admixture of patients with schizophrenia. Only oral paliperidone extended release (ER), paliperidone long-acting injection (LAI), and risperidone have been shown to be effective and safe in reducing psychotic as well as affective components in acutely ill SAD patients in controlled studies. Paliperidone ER and LAI have also been shown to be efficacious in the maintenance treatment phase of SAD patients. While no supportive data exist, it is possible that other atypical antipsychotics may have similar efficacy to the two mentioned above. We conclude with a number of research recommendations for the study of treatment options for patients with SAD. First, there is a need for studies with patients specifically diagnosed with SAD for both the acute and the maintenance phase. The sample size needs to be adequate to allow a primary analysis of efficacy and to allow for analysis of the SAD subtypes: depressed and bipolar. Another recommendation is the need for studies of patients with SAD stratified into patients with and without mood stabilizers or antidepressants to allow the examination of the adjunctive role of

    Persistent population aging worldwide is focusing attention on modifiable factors that can improve later life health. There is evidence that religiosity and spirituality are among such factors. Older people tend to have high rates of involvement in religious and/or spiritual endeavors and it is possible that population aging will be associated with increasing prevalence of religious and spiritual activity worldwide. Despite increasing research on religiosity, spirituality and health among older persons, population aging worldwide suggests the need for a globally integrated approach. As a step toward this, we review a subset of the literature on the impact of religiosity and spirituality on health in later life. We find that much of this has looked at the relationship between religiosity/spirituality and longevity as well as physical and mental health. Mechanisms include social support, health behaviors, stress and psychosocial factors. We identify a number of gaps in current knowledge. Many previous studies have taken place in the U.S. and Europe. Much data is cross-sectional, limiting ability to make causal inference. Religiosity and spirituality can be difficult to define and distinguish and the two concepts are often considered together, though on balance religiosity has received more attention than spirituality. The latter may however be equally important. Although there is evidence that religiosity is associated with longer life and better physical and mental health, these outcomes have been investigated separately rather than together such as in measures of health expectancy. In conclusion, there is a need for a unified and nuanced approach to understanding how religiosity and spirituality impact on health and longevity within a context of global aging, in particular whether they result in longer healthy life rather than just longer life.

    There are 55 operating commercial light water reactor plants (32 BWRs and 23 PWRs) in Japan. Twelve (12) plants have been operating for more than 30 years. Utility companies are required to perform an 'Ageing Management Technical Assessment' be-fore the end of 30 years operation of each plant. The assessments for each plant have been evaluated by the Nuclear and Industry Safety Agency (NISA) of the Ministry of Economy Trade and Industry (WTI) for these 12 plants. The Japan Nuclear Energy Safety Organisation (JNES) has compiled Technical Review Manuals for six major degradation phenomena for the evaluation of Ageing Management Technical Assessment. A 'Road-map for Ageing and Plant Life Management' was established in 2005 by the Special Committee in the Atomic Energy Society of Japan under the commission from the JNES. Within the framework of the road-map, the major research and development fields are divided into the following four categories: 1) engineering information systems; 2) research and development of technologies for inspection, evaluation and repair of the components and materials; 3) development of codes and standards; 4) synthesised maintenance engineering. Continuous revision of the 'Strategy Maps for Ageing Management and Safe Long-term Operation' has been performed under the Coordinating Committee of Ageing Management to promote research and development activities by industries, government and academia, effectively and efficiently. Systematic development of the information basis for database and knowledge-base has been undertaken in addition to the development of codes and standards by academic societies through intensive domestic safety research collaborations and international collaboration.

    Full Text Available The main aim of this research is to highlight age management within Slovenian enterprises from the viewpoint of older employees by finding out what influences older employees to decide “should I stay or should I go”. The empirical research methodology is based on mixed strategy of approaching organizations (employees, which means that the quantitative (factor analysis, cluster analysis, correlation, regression, descriptive statistics and frequency distributions and qualitative parts (in-depth interviews analysis of research were conducted simultaneously. The results of the research indicate that there are in fact two groups of older employees, which can be referred to as “susceptible” and “insusceptible” in terms of how the employer can affect their decisions. “The unsusceptible” have already decided to retire as soon as possible and they cannot be influenced by any employer measure. On the other hand, “the susceptible” employees are sensitive to employers’ measures aimed at prolonging their working lives. Besides, a regression analysis confirmed a statistically significant correlation between the inclination towards extending one’s employment period and the susceptibility to the employer measures. It can thus be concluded that, through age management measures, an employer has an impact on an extended employment period of older employees. However, employers should be interested primarily in those employees who are inclined towards extending their working lives.

  5. Engineering Center contribution to the Russian NPP aging management

    The Engineering Center of strength, reliability and life of the nuclear equipment of the Minatom, Russia, has been set up by the decision of the management of the Russian Federation Ministry on the nuclear power (Russia Minatom) within the framework of the Research and Development Institute of Power Engineering (RDIPE). The Engineering Center is responsible for fulfilling the functions of the leading Institution of the Ministry concerning these issues and it is in charge of the development of the appropriate rules and standards package as well as their compliance with analogous international regulating documents. To put forward the national program on NPP aging management, and to implement it is one of the crucial tasks of the Engineering Center. This activity is conducted by both the cooperation between Russian Institution and experts and within the framework of the international collaboration. In the latter case it is worthy of noting the activity with respect to the American-Russian Working Group 12 ''NPP Aging and Life Extension'' and participation in appropriate programs of the IAEA. The major trends of the above activity are considered in this paper

    2012-01-01

    Based on the Atomic Energy Act, the NRC issues licenses for commercial power reactors to operate for up to 40 years and allows these licenses to be renewed for up to another 20 years. NRC has approved license renewal for well over 50% of U.S. located reactors originally licensed to operate for 40 years. Of these 104 reactors (69 PWRs, 35 BWRs), the NRC has issued renewed licenses for 71 units and is currently reviewing applications for another 15 units. As of May 1, 2012, ten plants at nine sites had entered their 41st year of operation and thus are in their first period of extended operation (PEO). Five more plants will enter the PEO by the end of 2012. One foundation of the license renewal process has been license renewal guidance documents (LRGDs). The U.S. Nuclear Regulatory Commission (NRC) revised key guidance documents used for nuclear power license renewal in 2010 and 2011. These include NUREG-1800, 'Standard Review Plan for Review of License Renewal Applications,' revision 2 (SRP-LR), and NUREG-1801, 'Generic Aging Lessons Learned (GALL) Report,' revision 2 (GALL Report). The guidance documents were updated to reflect lessons learned and operating experience gained since the guidance documents were last issued in 2005. (author)

  8. Ageing Management Programs for Electrical Cables in Slovak NPPs

    International Nuclear Information System (INIS)

    Rovny, Karol

    2012-01-01

    One of the key factors, which are negatively affecting the operational safety of nuclear power plants, is the process of ageing. The need for the elimination of these ageing related damages is self-evident and naturally of the highest priority, to preserve the operational safety and reliability. Keeping in mind the safety and reliability of operated devices, and on the other hand the effort to maximize the device utilization, it is recommended to introduce and implement the programs for the monitoring and management of ageing of individual systems, structures and components (SSC). These shall ensure the possibility to monitor and evaluate the effects of degeneration processes on the selected SSC's , to monitor the trends in the parameters measured and ensure the adoption of appropriate corrective actions in real time. The number of nuclear reactors, which are exceeding the originally assumed operational longevity, as defined by original project documentation, is rapidly increasing. It is to no surprise that the demand for their extended operational longevity is increasing hand in hand with the strengthening safety and regulatory requirements worldwide. Each nuclear power plant consists of, among others, kilometers and miles of electric and I and C cables. Their task is irreplaceable, and their excellent condition is vital for the safety and reliability of seamless power plant operation. Thus it is critical and essential to recognize and monitor the real performance of the cables, and to implement programs, which monitor their actual condition. A successful implementation of ageing programs is a cornerstone of safe power plant operations in a long run. The focus of this presented paper is the defined approach, stated goals, and the results achieved in the area of cable ageing and longevity monitoring in the environment of Slovak nuclear power plants.

    How long the nuclear plants can get. In this question we can find three main aspects: Economic - Licensing - and Technical ones. The final answer to this question will include compulsory elements coming from these three areas, each of them being a deciding factor. The presentation is focused on the technical aspect; but before a few comments are done on economic and licensing factors. Then, some particular technical items dealing with aging or life time of our nuclear plants are reviewed: electrical equipment, heat exchangers (steam generators), wear: primary pump, embrittlement: Reactor Pressure Vessel (Austeno-ferritic parts), fatigue (Thermo-hydraulic transients). By the way, some information about how this problem is handled, at the present time, explicitely or implicitely in France are given

    The Spacelab development program is a joint undertaking of the NASA and ESA. The paper addresses the initial concept of Spacelab payload mission management, the lessons learned, and modifications made as a result of the actual implementation of Spacelab Mission 1. The discussion covers mission management responsibilities, program control, science management, payload definition and interfaces, integrated payload mission planning, integration requirements, payload specialist training, payload and launch site integration, payload flight/mission operations, and postmission activities. After 3.5 years the outlined overall mission manager approach has proven to be most successful. The approach does allow the mission manager to maintain the lowest overall mission cost.

    The management of epistaxis requires an understanding of haematological factors that may complicate its treatment. This systematic review includes six distinct reviews examining the evidence supporting epistaxis-specific management strategies relating to warfarin, direct oral anticoagulants, heparin, antiplatelet agents, tranexamic acid and transfusion. A systematic review of the literature was performed using a standardised methodology and search strategy. Limited numbers of articles were identified in each systematic review, with level 1 evidence only regarding the use of tranexamic acid. No studies met the inclusion criteria within the heparin, direct oral anticoagulants or transfusion systematic reviews. Many studies were limited by small sample sizes and significant risk of bias. The management of major bleeding and transfusion practice is well documented in national guidance from multiple sources. The guidelines include advice on anticoagulants, antiplatelet agents and tranexamic acid. In the absence of more specific evidence, these guidelines should be applied in the management of epistaxis.

    2015-01-01

    This paper proposes a new approach to Ageing Probabilistic Safety Assessment (APSA) modelling, which is intended to be used to support risk-informed decisions on the effectiveness of maintenance management programs and technical specification requirements of critical equipment of Nuclear Power Plants (NPP) within the framework of the Risk Informed Decision Making according to R.G. 1.174 principles. This approach focuses on the incorporation of not only equipment ageing but also effectiveness of maintenance and efficiency of surveillance testing explicitly into APSA models and data. This methodology is applied to a motor-operated valve of the auxiliary feed water system (AFWS) of a PWR. This simple example of application focuses on a critical safety-related equipment of a NPP in order to evaluate the risk impact of considering different approaches to APSA and the combined effect of equipment ageing and maintenance and testing alternatives along NPP design life. The risk impact of several alternatives in maintenance strategy is discussed

    2014-01-01

    The Zero Energy Deuterium (ZED-2) Research Reactor first achieved criticality in 1960 September. Ageing of Systems, Structures and Components (SSCs) as well as the obsolescence of many original components had led to the Facility being in a reactive mode with respect to maintenance rather than a preventative maintenance mode. Through the implementation of an Ageing Management Plan to access the effects of Ageing Related Degradation Mechanisms (ARDMs) on SSCs and a Critical Spare Parts Obsolescence Plan (establishing new specifications for components, procurement of new components and building a replacement inventory) the Facility is returning to a preventative maintenance state rather than a reactive maintenance state. Upgrades and refurbishment of the original equipment and components is underway within the Facility. This paper describes the programs being carried out in the Facility and focuses on the upgraded nuclear electronics, renewed moderator level control system and spare parts inventory system. Implementation of the above mentioned programs will enable the Facility to continue to fulfill its mandate as an integral part of AECL's Vision and Strategic Outcome: 'To be a global partner in nuclear innovation' and that 'Canadians and the world receive energy, health, environmental and economic benefits from nuclear science and technology with confidence that nuclear safety and security are assured', respectively.

    2002-01-01

    Life Cycle Management is a structured process to manage equipment aging and long-term equipment reliability for nuclear plant Systems, Structures and Components (SSCs). The process enables the identification of effective repair, replace, inspect, test and maintenance activities and the optimal timing of the activities to maximize the economic value to the nuclear plant. This paper will provide an overview of the process and some of the tools that can be used to implement the process for the SSCs deemed critical to plant safety and performance objectives. As nuclear plants strive to reduce costs, extend life and maximize revenue, the LCM process and the supporting tools summarized in this paper can enable development of a long term, cost efficient plan to manage the aging of the plant SSCs.

    Brown, Charlotte; Milke, Mark; Seville, Erica

    2011-06-01

    Depending on their nature and severity, disasters can create large volumes of debris and waste. The waste can overwhelm existing solid waste management facilities and impact on other emergency response and recovery activities. If poorly managed, the waste can have significant environmental and public health impacts and can affect the overall recovery process. This paper presents a system overview of disaster waste management based on existing literature. The main literature available to date comprises disaster waste management plans or guidelines and isolated case studies. There is ample discussion on technical management options such as temporary storage sites, recycling, disposal, etc.; however, there is little or no guidance on how these various management options are selected post-disaster. The literature does not specifically address the impact or appropriateness of existing legislation, organisational structures and funding mechanisms on disaster waste management programmes, nor does it satisfactorily cover the social impact of disaster waste management programmes. It is envisaged that the discussion presented in this paper, and the literature gaps identified, will form a basis for future comprehensive and cohesive research on disaster waste management. In turn, research will lead to better preparedness and response to disaster waste management problems. Copyright © 2011 Elsevier Ltd. All rights reserved.

    2013-02-01

    The purpose of this report is to describe programs and tools for assessment of accomplished and documented qualification with respect to ageing of electrical equipment and for development of complimentary ageing management programs. In addition to description of complete programs for management of ageing, tools for validation of the status with regard to ageing of installed ('old') equipment and, where needed, for complementation of their qualification are also included. The report is restricted to safety related equipment containing ageing sensitive parts, mainly organic materials. To this category belong cables and cable joints and a number of equipment containing oils, seals (o-rings), etc. For equipment located in the containment, the possibilities of continuous supervision are limited. The accessibility for regular inspections is also limited in many cases. The main part of this report deals with the qualification of such equipment. Some safety related equipment outside the containment can be located in areas where they are subjected to high temperature and other excessive environmental stresses during normal operation and in areas affected by an accident. Therefore, some material is given also on qualification of equipment located outside containment with better possibilities for frequent inspection and supervision. Part 1 of the report is an executive summary with a general review of the methodologies and their application. The more detailed description of the programs and underlying material, useful data, etc. is given in Part 2

    1998-01-01

    The US Department of Energy (DOE), in cooperation with the Electric Power Research Institute (EPRI) and US nuclear power plant utilities, is preparing a series of aging management guidelines (AMGs) for commodity types of components (e.g., heat exchangers, electrical cable and terminations, pumps). Commodities are included in this series based on their importance to continued nuclear plant operation and license renewal. The AMGs contain a detailed summary of operating history, stressors, aging mechanisms, and various types of maintenance and surveillance practices that can be combined to create an effective aging management program. Each AMG is intended for use by the systems engineers and plant maintenance staff (i.e., an AMG is intended to be a hands-on technical document rather than a licensing document). The heat exchangers AMG, published in June 1994, includes the following information of interest to nondestructive examination (NDE) personnel: aging mechanisms determined to be non-significant for all applications; aging mechanisms determined to be significant for some applications; effective conventional programs for managing aging; and effective unconventional programs for managing aging. Since the AMG on heat exchangers was published four years ago, a brief review has been conducted to identify emerging regulatory issues, if any. The results of this review and lessons learned from the collective set of AMGs are presented

    Nopper, Helmut; Rossner, Roland; Zander, Andre

    2006-01-01

    Within the scope of PLEX, a systematic and efficient ageing and plant life management system is becoming more and more important to ensure a safe and economical power plant operation in spite of continuous plant ageing. For the methodical implementation of PLIM and PLEX strategies, AREVA NP has developed the software tool COMSY. This knowledge-based program integrates degradation analysis tools with an inspection data management system. COMSY provides the capability to establish a program guided technical documentation by utilizing a virtual plant model which includes information regarding thermal hydraulic operation, water chemical conditions and materials applied for mechanical components. It provides the option to perform a plant-wide screening for identifying system areas, which are sensitive for degradation mechanisms typically experienced in nuclear power plants (FAC, corrosion fatigue, IGSCC, Pitting, etc.). If a system area is identified as being susceptible to degradation, a detailed analysis function enables the condition-oriented service life evaluation of vessels and piping systems in order to localize and conservatively quantify the effect of degradation. Based on these forecasts with COMSY, specific strategies can be developed to mitigate the effect of degradation and inspection activities can be focused on degradation sensitive areas. In addition, a risk-informed assessment tool serves to optimize inspection activities in respect to degradation potential and the associated damage consequence. After an in-service inspection is performed for a distinct location, the inspection data is to be evaluated according to generally accepted procedures. For this purpose an integrated inspection data management system module provides standardized, interactively operated evaluation functions. The key inspection results are transmitted as feedback in respect to the as-is condition of the component. Subsequently, all further life evaluations of the associated

    Up to 80% of residents in aged care facilities (ACFs) experience pain, which is often suboptimally managed. The purpose of this study was to characterize pain management in ACFs and identify the barriers to optimal pain management. This exploratory descriptive qualitative study used semistructured interviews in five Southern Tasmania, Australian ACFs. Interviewees included 23 staff members (18 nurses and 5 facility managers) and were conducted from September to November 2015. Interviews included questions about how pain was measured or assessed, what happened if pain was identified, barriers to pain management, and potential ways to overcome these barriers. Interviewees noted that there were no formal requirements regarding pain assessment at the ACFs reviewed; however, pain was often informally assessed. Staff noted the importance of adequate pain management for the residents' quality of life and employed both nonpharmacologic and pharmacologic techniques to reduce pain when identified. The barriers to optimal pain management included difficulty identifying and assessing pain, residents' resistance to reporting pain and/or taking medications, and communication barriers between the nursing staff and GPs. Staff interviewed were dedicated to managing residents' pain effectively; however, actions in a number of areas could improve resident outcomes. These include a more consistent approach to documenting pain in residents' progress notes and improving nurse-GP communications to ensure that new or escalating pain is identified and expedient changes can be made to the resident's management. Additionally, resident, family, nurse, and carer education, conducted within the facilities on a regular basis, could help improve the pain management of residents. Copyright © 2017.

  6. Policy options to improve leadership of middle managers in the Australian residential aged care setting: a narrative synthesis

    Science.gov (United States)

    2010-01-01

    Background The prevalence of both chronic diseases and multi-morbidity increases with longer life spans. As Australia's population ages, the aged care sector is under increasing pressure to ensure that quality aged care is available. Key to responding to this pressure is leadership and management capability within the aged care workforce. A systematic literature review was conducted to inform the policy development necessary for the enhancement of clinical and managerial leadership skills of middle managers within residential aged care. Methods Using scientific journal databases, hand searching of specialist journals, Google, snowballing and suggestions from experts, 4,484 papers were found. After a seven-tiered culling process, we conducted a detailed review (narrative synthesis) of 153 papers relevant to leadership and management development in aged care, incorporating expert and key stakeholder consultations. Results • Positive staff experiences of a manager's leadership are critical to ensure job satisfaction and workforce retention, the provision of quality care and the well-being of care recipients, and potentially a reduction of associated costs. • The essential attributes of good leadership for aged care middle management are a hands-on accessibility and professional expertise in nurturing respect, recognition and team building, along with effective communication and flexibility. However, successful leadership and management outcomes depend on coherent and good organisational leadership (structural and psychological empowerment). • There is inadequate preparation for middle management leadership roles in the aged care sector and a lack of clear guidelines and key performance indicators to assess leadership and management skills. • Theory development in aged care leadership and management research is limited. A few effective generic clinical leadership programs targeting both clinical and managerial leaders exist. However, little is known regarding

    A variety of interventions have been proposed to manage rising demand for Emergency and Urgent Care, described by an NHS England review as unsustainable in the long term. However it is unlikely that any suggested approach will be equally suitable for the diverse population of ED users.We aimed to understand the patterns of demand amongst different types of patients attending ED. We also sought to understand the intended and unintended effects of demand management initiatives. Our study combined insights from routine data, a survey of ED patients, and qualitative interviews with ED staff. This paper describes the results of our analysis of the interviews. We conducted semi-structured interviews with 25 ED and Urgent Care Centre staff across 7 hospital sites in Yorkshire and Humber between 25 April and 11 July 2016. The interview topic guide asked about 4 broad areas; job role, description of patients and their impact on demand, description of inappropriate attendance, and current/future initiatives to deal with rising demand. Interviews were transcribed verbatim and analysed using framework analysis. We analysed the results to identify groups of patients with different patterns of use of ED services. We also explored ED staff experiences of demand management initiatives, and their suggestions for future initiatives. Although we did not ask specifically about patients' age, our analysis revealed that ED staff categorised attenders as children and young people, working age people, and older people. These groups had different reasons for attendance, different routes to the ED, different rate of non-urgent attendance, and different issues driving demand. Staff also described variation in the time taken to treat patients of different ages, with the oldest and youngest patients described as requiring the most time.There was no consensus amongst staff about the effectiveness of initiatives for managing demand. A strikingly wide variety of initiatives were mentioned

    The scope of this work includes the study of all feedwater heaters (from 1 to 6) in their two trains (A and B). In this study the main degradation phenomena that affect them, the operating parameters that can warn of a possible malfunction of the heater and possible strategies inspection, repair and replacement are analyzed. As a result of this study, a higher priority is obtained at a lower state of degradation of the heaters, possibly with a strategy inspection, repair or replacement, for each recharge, until the end of life of the plant. This will be a live program, which must be fed back to the studies of the parameters of operation of the heater during operation and results of the inspection of each recharge. May verify the effectiveness of aging management program using different indicators. (Author)

  9. Approach of British Nuclear Fuels to managing ageing

    International Nuclear Information System (INIS)

    2006-01-01

    The approach taken by BNFL to managing ageing is developed at the design stage and builds upon experience gained through designing, building, operating and decommissioning nuclear facilities since 1947. Much of the current philosophy was developed during the design and construction of the Thermal Oxide Reprocessing Plant (THORP). The process of managing ageing encompasses all the phases of the facility's life; that is, design, operation and decommissioning. Underlying all these phases is the input from the results of research and development and plant inspection activities. Plant ageing is managed by a policy of understanding the degradation mechanisms as far as possible and, from that knowledge, targeting for particular attention plants considered as vulnerable or for which we are uncertain of our understanding of the degradation processes; for example, THORP receipt and storage LWR storage racks have been fabricated from 304L stainless steel. In their storage environment, deionized water, the worst case measured corrosion rate for such steels is 0.03 mm/a. Given that the minimum material thickness used is 20 mm, corrosion over the design life is negligible and therefore there are no prescribed monitoring or maintenance requirements. Plant inspection policy was first developed for THORP, where targeted programmes of inspection are established. Inspection may be limited to visual inspection or may involve quantitative non-destructive testing such as ultrasonics, and in certain areas, such as dissolvers, on-line thickness monitors have been installed to facilitate the process. The programmes are updated as the actual plant operating conditions are better known and understood; therefore, for example, an SSC found to be operating at higher temperatures than originally planned or carrying a higher burden of corrodents may become targeted for inspection, whereas SSCs perceived to be benign may have inspection frequencies reduced. Similar policies are being developed for

    Abnormal uterine bleeding is a common gynecological disease and represents one of the most frequent reasons for hospital admission to a specialist unit, often requiring further surgical treatment. Following the so-called PALM-COEIN system we will attempt to further clarify the surgical treatments available today. The first group (PALM) is characterized by structural lesions, which may be more appropriately treated by means of surgical management. Although hysterectomy remains the definitive and decisive choice, there are many alternative techniques available. These minimally invasive procedures offer the opportunity for a more conservative approach. Precise and accurate counseling facilitates better patient selection, based on the patient's desires, age and disease type, allowing treatment to be individually tailored to each woman.

    The HVAC(heating, ventilation and air conditioning) systems in nuclear power plants are consisted of fan, damper, duct, filter and cooling coil, which is equipped in the safety-related building such as main control room, auxiliary building and containment building. These systems are designed to maintain the required ambient air temperature in all plant areas for the comfort and safety of personnel and for environmental requirement of equipment and to ensure that the gaseous radioactivity emission to the environment is kept below permissible discharge limits. The purpose of this study is to establish the inspection plan to ensure that touch up parts of the duct are sound and to develop the aging management program for maintaining effectively HVAC systems

    Background  Continence Management within residential aged care is an every day component of care that requires assessment, implementation of strategies, resource allocation and evaluation. At times the management of incontinence of aged residents can be challenging and unsuccessful. The project chosen through the Clinical Fellowship program was Continence Management with the aim of raising awareness of best practice to assist in improving and providing person-centred resident care. Aims/objectives •  Review the literature on best practice management of incontinence •  Evaluate current practice in continence management for elderly residents within residential aged care services •  Improve adherence to best practice strategies of care for incontinence •  Raise awareness within the nursing home of the best practice management of incontinence •  Promote appropriate and effective use of resources for continence management •  Deliver individualised person-centred care to residents. •  Ensure best practice in continence management Methods  The Joanna Briggs Institute (JBI) Practical Application of Clinical Evidence System clinical audit tool was utilised to measure current practice against best practice. The results identify gaps that require improvement. The Getting Research into Practice process then allowed analysis of the level of compliance with each of the audit criteria, which would identify any barriers in implementing a selected course of action and aim to improve compliance. The project team was consulted with additional stakeholder consultation to form an action plan and implement strategies to improve practice. Results  Although 100% compliance with all audit criteria in audit 1 and 2 was not achieved, there was improvement in the criteria concerning the documented fluid intake for residents. Further strategies have been identified and implemented and this continues to be a 'work in progress'. Staff now have an acute awareness

    2012-01-01

    Purpose The purpose of this study was to review the principles involved in the management of proximal femoral fractures as reported in the literature. Methods: A medical literature search in the MEDLINE (PubMed) and Cochrane database was undertaken to review strategies and principles in proximal femoral fracture treatment. Randomized control trials and meta analysis were given preference while case reports/small series were rejected. Results and conclusions: Early anatomical reduction and surgical fixation remains the best option to reduce the risk of complications like non-union and avascular necrosis in treating fracture neck femurs. Cancellous screws continue to be the preferred treatment for fixation of neck femur fractures in younger population until the benefit of using sliding hip screws is validated by large multicentric studies. In the geriatric age group, early prosthetic replacement brings down the mortality and morbidity associated with neck femur fractures. Sliding hip screw (DHS) is the best available option for stable inter trochanteric fractures. The use of intramedullary nails e.g. PFN is beneficial in treating inter trochanteric fractures with comminution and loss of lateral buttress. Intramedullary implants have been proven to have increased success rates in subtrochanteric fractures and should be preferred over extramedullary plate fixation systems. PMID:25983451

    Rib fractures can cause significant problems in trauma patients, often resulting in pain and difficulty with respiration. To prevent pulmonary complications and decrease the morbidity and mortality rates of patients with rib fractures, currently there is a trend to provide surgical management of patients with flail chest. However, the indications for rib fracture fixation require further specification. Past and current strategies are described according to a review of the medical literature. A systematic review was performed including current indications for rib fracture fixation. MEDLINE (2000-2013) was searched, as well as Embase (2000-2013) and Cochrane Databases, using the keywords rib, fracture, fixation, plate, repair, and surgery. Three retrospective studies were found that described different techniques for rib fracture fixation. The results demonstrated a reduced number of ventilation days, decreased long-term morbidity and pain, and satisfactory rehabilitation after surgical treatment. In addition to flail chest, age, Injury Severity Score, and the number of rib fractures were important predictive factors for morbidity and mortality. Surgical rib fracture fixation might be indicated in a broader range of cases than is currently performed. Prospective randomized trials are needed for further confirmation. © The Finnish Surgical Society 2014.

    2014-10-01

    Full Text Available Youth unemployment is currently a stringent problem in many European countries. Most of the time, both the public opinion and the national and European institutions blame the economic crisis, the social conditioning of these youngsters, and point to the failure of the educational systems to provide them with the necessary qualifications needed on the market. There are a few initiatives, such as the Youth Guarantee launched in 2013, led by European public authorities in order to reduce this phenomenon, but these initiatives address solely the professional proficiency of the youngsters. And most authorities perceive them as citizens who need to be trained to fit with the existing working environments. The situation is, in fact, more complex, as todays youngsters are different from the previous generations in terms of the values they share and the basic way they process information. When speaking of the youth, the high unemployment rate due to system imbalance between people training and work fields’ requirements are just one side of the coin. The other side speaks about the impact digital technology has upon young people, favouring the emergence of the so called digital natives, and about the fact that the working environment in itself has to incorporate changes in order to accommodate these youngsters and fully benefit from their capabilities.     As Romanian digital natives come of age, minimizing the mind gap between elder managers and younger employees and candidates becomes an important issue that companies increasingly have to deal with. This article explores the digital natives’ expectations from their managers and from the companies they aim to work for, based upon a survey conducted in four universities in Bucharest. We propose a series of recommendations for managers who work closely with digital natives, in order to improve the work environment and create the premises for better job performance in their teams, possibly reducing

    Fast Breeder Test Reactor is a 40 MWt, sodium cooled, PuC-UC fuelled fast reactor, located at Kalpakkam, India. The reactor went critical in October 85 with Mark I core rated for 10.5 MWt at a peak LHR of 320 W/cm. The reactor core was progressively enlarged and TG was synchronized to the grid in July 97. The present core has 41 fuel subassemblies rated for 15.7 MWt at a peak LHR of 320 W/cm. The reactor has so far been operated for 33000 h and has seen 660 EFPD of operation corresponding to peak LHR of 320 W/cm. The peak burnup reached by the carbide fuel is 127 GWd/t, without any fuel clad failure. The four sodium pumps have been operating satisfactorily for a cumulative time of more than 5,00,000 h. Creep, fatigue and fluence govern the life of the nuclear systems. Because of the reduced power and temperature at which the reactor has so far been operated, there is little ageing of the nuclear systems. The life of the nuclear components is being monitored by periodic surveillance. Periodic assessment of the fluence seen by reactor components is being made. The conventional systems have been in service for the past 19 years. Civil structures are 25 years old. These have been maintained by periodic preventive maintenance and replacement / repair wherever required. This paper details the various ageing management practices in FBTR. (author)

    Full Text Available In Latvia, the number of aging employees suffering from sleep disorders caused by job stress and poor sleep hygiene is increasing. The non-pharmacologic and pharmacologic treatment is prescribed for these employees in the sleep management. The aim of this research is to clarify the efficiency of using psychotherapy with learning and observing sleep hygiene, combined with the melatonergic drug during a six-week treatment course applied to 25 both male and female intellectual workers over 65 years suffering from insomnia caused by job stress. For the patients representing Group “A” cognitive hypnotherapy, intervention for improving coping with job stress and usage of the melatonergic drug was prescribed, while Group “B” patients received six weeks only drug. The severity of depressive episodes in employees was measured by Montgomery- Åsberg Depression Rating Scale, the level of anxiety was assessed by use Rosenberg Self-Esteem Scale. The results of the research show that insomnia patterns disappeared for 75% of women and 80% of men employees in Group A, but in Group B individuals, – only for 20% of women employees. The results acquired let concluding that the six-week treatment – cognitive hypnotherapy combined with melatonergic drug – is an effective treatment for aging workers suffering from sleep disorders.

    2016-12-01

    In spite of an increased interest in open innovation and strategies that call for an increased collaboration between different healthcare actors, there is a lack of open innovation research in public contexts. This article presents the results of a review regarding the healthcare sector's engagement in open innovation as well as constraining factors and positive outcomes of open innovation in healthcare. The literature search focused on papers published in English between 2003 and 2014. Based on specified inclusion criteria, 18 articles were included. Results reveal that most studies focus on inbound open innovation where external knowledge is integrated with the internal knowledge base at an initial phase of the innovation process. Innovation primarily results in products and services through innovation networks. We also identified constraining factors for open innovation in healthcare, including the complex organizations of healthcare, the need to establish routines for capturing knowledge from patients and clinicians, regulations and healthcare data laws as well as the positive outcome patient empowerment. The healthcare sector's engagement in open innovation is limited, and it is necessary to perform further research with a focus on how open innovation can be managed in healthcare. © The Author(s) 2016.

    2017-01-01

    Aim of the study: To review and acknowledge the value of carbon sequestration by forest management in the Mediterranean area. Material and methods: We review the main effects of forest management by comparing the effects of silviculture systems (even-aged vs. uneven-aged stands, coppice systems, agroforestry systems), silvicultural options (thinning, rotation period, species composition), afforestation, harvesting, fire impact or effects of shrub layer on carbon sequestration in the Mediterranean area. Main results: We illustrate as forest management can clearly improve forest carbon sequestration amounts. We conclude that forest management is an effective way to maintain and enhance high carbon sequestration rates in order to cope with climate change and provision of ecosystem services. We also think that although much effort has been put into this topic research, there are still certain gaps that must be dealt with to increase our scientific knowledge and in turn transfer this knowledge to forest practitioners in order to achieve sustainable management aimed at mitigating climate change. Research highlights: It is important to underline the importance of forests in the carbon cycle as this role can be enhanced by forest managers through sustainable forest management. The effects of different management options or disturbances can be critical as regards mitigating climate change. Understanding the effects of forest management is even more important in the Mediterranean area, given that the current high climatic variability together with historical human exploitation and disturbance events make this area more vulnerable to the effects of climate change

    2016-12-01

    We systematically reviewed treatment modalities for MIH-affected molars and incisors. Trials on humans with ≥1 MIH molar/incisor reporting on various treatments were included. Two authors independently searched and extracted records. Sample-size-weighted annual failure rates were estimated where appropriate. The risk of bias was assessed using the Newcastle-Ottawa scale. Electronic databases (PubMed, Embase, Cochrane CENTRAL, Google Scholar) were screened, and hand searches and cross-referencing performed. Fourteen (mainly observational) studies were included. Ten trials (381 participants) investigated MIH-molars, four (139) MIH-incisors. For molars, remineralization, restorative or extraction therapies had been assessed. For restorative approaches, mean (SD) annual failure rates were highest for fissure sealants (12[6]%) and glass-ionomer restorations (12[2]%), and lowest for indirect restorations (1[3]%), preformed metal crowns (1.3 [2.1]%) and composite restorations (4[3]%). Ony study assessed extraction of molars in young patients (median age 8.2 years), the majority of them without malocclusions, but third molars in development. Spontaneous alignment of second molars was more frequent in the maxilla (55%) than the mandible (47%). For incisors, desensitizing agents successfully managed hypersensitivity. Micro-abrasion and composite veneers improved aesthetics. Few, mainly moderate to high-risk-studies investigated treatment of MIH. Remineralization or sealants seem suitable for MIH-molars with limited severity and/or hypersensitivity. For severe cases, restorations with composites or indirect restorations or preformed metal crowns seem suitable. Prior to tooth extraction as last resort factors like the presence of a general malocclusion, patients' age and the status of neighboring teeth should be considered. No recommendations can be given for MIH-incisors. Dentists need to consider the specific condition of each tooth and the needs and expectations of

  14. Nongenetic Determinants of Age at Menarche: A Systematic Review

    Full Text Available Background. The acceleration of pubertal development is an important medical and social problem, as it may result in increased morbidity and mortality in later life. This systematic review summarizes relevant data about nongenetic factors, which contribute to age at menarche (AAM, and suggests those which may be the most important. Methods. The available literature from 1980 till July 2013 was searched using PubMed and Google Scholar databases. Finally, 154 papers were selected for the analysis. Results. Environmental factors, which may affect AAM, vary in populations of different ethnicity. The prenatal, infancy, and early childhood periods are the most susceptible to these factors. Body weight, high animal protein intake, family stressors (e.g., single parenting, and physical activity seem to influence AAM in most populations. Conclusions. The data about influence of nongenetic factors on AAM are still inconsistent. The factors affecting prenatal and early childhood growth seem to have a larger effect on further sexual maturation. Further studies are needed in order to validate the association between other environmental determinants and AAM in different ethnical groups.

    Full Text Available Introduction: Vascular anomalies are congenital lesions broadly categorised into vascular tumour (haemangiomas and vascular dysmorphogenesis (vascular malformation. The management of these difficult problems has lately been simplified by the biological classification and multidisciplinary approach. To standardise the treatment protocol, an algorithm has been devised. The study aims to validate the algorithm in terms of its utility and presents our experience in managing vascular anomalies. Materials and Methods: The biological classification of Mulliken and Glowacki was followed. A detailed algorithm for management of vascular anomalies has been devised in the department. The protocol is being practiced by us since the past two decades. The data regarding the types of lesions and treatment modality used were maintained. Results and Conclusion: This study was conducted from 2002 to 2012. A total of 784 cases of vascular anomalies were included in the study of which 196 were haemangiomas and 588 were vascular malformations. The algorithmic approach has brought an element of much-needed objectivity in the management of vascular anomalies. This has helped us to define the management of particular lesion considering its pathology, extent and aesthetic and functional consequences of ablation to a certain extent.

  10. Assessment and Management of Aging in Phenix Nuclear Power Plant

    International Nuclear Information System (INIS)

    Dumarcher, V.; Bourrier, J.L.; Chaucheprat, P.; Boulegue, D.

    2006-01-01

    The combination of one or several processes of ruins can involve the materials failure of a nuclear power plant. These processes arise from the external agents action such as the pressure, the mechanical efforts, the heat flows and the radiations constitute the whole of the 'actions' of the surrounding medium. The prolongation and the repetition of these effects can involve a deterioration of the machine. In accordance with the decree of February 26, 1974, the PWR operator must be firstly, sure that the system is controlled according to the situations considered in the file of dimensioning and secondly, be able to know anytime the life of the equipment. The physical phenomena which cause the structures ruin are less complex in the PWR than in the SFR. In the SFR, the high temperatures imposed on components for long periods can involve a significant creep. In the course of time, this deformations accelerate the release of fatigue cracks. To consider the creep, the reactor lifespan is correlated at the numbers of thermals transients envisaged initially. To realize the management of aging in Phenix power plant, it is necessary to carry out an individualized monitoring of the structures and not only on the vessel. We must ensure the good state and/or the correct operation of the significant stations for safety which are the control of the reactivity, the movement of control rods, the primary sodium containment and the decay heat removal. For that, we monitor the main vessel, the conical skirt, the IHX and the Core Cover Plug. A profound knowledge of the thermal transients of the past is necessary to carry out an effective assessment. In order to guarantee that any harmful situation is well taken into the management of aging, we monitor permanently certain measurements (primary and secondary pump speed, hot and cold pool temperatures, IHX-main vessel and reactor roof temperatures). We present in the article the scientific method used in the Physics Section. A logical

    Conegundes De Jesus, Camila Kiyomi; Salerno, Mario Sergio

    2018-05-09

    Patents and patent portfolios are gaining attention in the last decades, from the called 'pro-patent era' to the recent billionaire transactions involving patent portfolios. The field is growing in importance, both theoretically and practically and despite having substantial literature on new product development portfolio management, we have not found an article relating this theory to patent portfolios. Areas covered: The paper develops a systematic literature review on patent portfolio management to organize the evolution and tendencies of patent portfolio management, highlighting distinctive features of patent portfolio management. Interview with IP manager of three life sciences companies, including a leading multinational group provided relevant information about patent portfolio management. Expert opinion: Based on the systematic literature review on portfolio management, more specifically, on new product development portfolio theory, and interview the paper proposes the paper proposes a reference model to manage patent portfolios. The model comprises four stages aligned with the three goals of the NPD portfolio management: 1 - Linking strategy of the Company's NPD Portfolio to Patent Portfolio; 2 - Balancing the portfolio in buckets; 3 - Patent Valuation (maximizing valuation); 4 - Regularly reviewing the patent portfolio.

  16. Leadership and Registered Nurses (RNs) working after-hours in Residential Aged Care Facilities (RACFs): A structured literature review.

    Science.gov (United States)

    Nhongo, Dorika; Hendricks, Joyce; Bradshaw, Julie; Bail, Kasia

    2018-06-12

    Registered nurses (RNs) working in Residential Aged Care Facilities are required to undertake complex management tasks including leading nursing care teams, supervising non-nursing staff, and allocating workloads according to residents' care needs, staff skills and experience. Registered nurses plan, assess, manage medication, evaluate each resident's care, liaise with doctors and allied health professionals and are responsible for evidence-based practice in accordance with the Nursing Standards for Practice (2016). Researchers have commented that effective nurse leadership can improve quality of care, improved resident outcomes and reduce adverse events. The aim of this literature review is to synthesise and analyse the literature pertinent to the RN's competence and confidence to undertake the leadership role when working in residential aged care facilities after-hours and to determine any association of leadership with quality resident outcomes. A review of original research papers based on the structured methodology described by Kable, Pich and Maslin-Prothero (2012). The review was conducted according to the 12-step structured framework by Kable et al. (2012). The search included peer-reviewed papers published between 2002 and 2017 on RN leadership after-hours, factors contributing to or with relationships to nursing leadership. Nineteen papers were found that researched the impact of leadership in aged care settings. The literature review concluded that nursing leadership has been linked to the quality of care and clinical outcomes in the aged care setting. However, RNs in the aged care setting have limited opportunities to develop key leadership competencies and confidence in order to meet the many challenges found in this environment due to lack of access to aged-care-specific leadership education. Minimal publications address the importance of the leadership of after-hours RNs. Results from this literature review will inform future research in this area

    International Nuclear Information System (INIS)

    Prasad, Y.S.R.; Srinivasan, V.S.

    1994-01-01

    A nuclear power plant is built with a certain design life but by managing the operation of the plant with a well designed in-service inspection, repair and replacement programme of the equipment as required we will be able to extend the operation of the plant well beyond it's design life. This is also economically a paying proposition in view of the astronomical cost of construction of a new plant of equivalent capacity. In view of this, there is a growing trend the world over to study the ageing phenomena, especially in respect of nuclear power plant equipment and system which will contribute towards the continued operation of the nuclear power plants beyond their economic life which is fixed mainly to amortize the investments over a period. Tarapur Atomic Power Station (TAPS) which consists of 2 nos. of Boiling Water Reactor (BWRs) with the presently rated capacity of 160 MWe each has been operating for the past 24 years and is completing its 25th year of service by the year 1994 which was considered as its economic life and the plant depreciation as well as fuel supply agreement were based on this period of 25 years. I will be discussing about the available residual life which is much more than the above (25 years) and the studies we have undertaken in respect of the assessment of this residual life.

    This report reviews R and D results and experiences forming the bases for the preparation of a report on management of ageing. It includes basic information and descriptions of value for persons who work with the questions and some data from investigations of the ageing characteristics of various materials: limit levels, dose-rate effects, activation energies, methods for condition monitoring, etc. This report is restricted to safety related components containing ageing sensitive parts, mainly organic materials (polymers). For components located in the containment, the possibilities of continuous supervision are limited. The accessibility for regular inspections is also limited in many cases. Therefore, the main part of this report deals with the qualification of such components. In addition, some material is given on qualification located outside containment with better possibilities for frequent inspection and supervision. A survey is made of activities, programs and tools for ageing qualification in connection with initial environmental qualification (type testing) as well as after installation (condition monitoring, extension of qualified life through on-going qualification). Tools are also given for supplementary ageing qualification of already installed components.

    2017-12-01

    The plastic-derived product, nowadays, becomes an indispensable commodity for different purposes. A huge amount of used plastic causes environmental hazards that turn in danger for marine life, reduces the fertility of soil, and contamination of ground water. Management of this enormous plastic waste is challenging in particular for developing countries like Bangladesh. Lack of facilities, infrastructure development, and insufficient budget for waste management are some of the prime causes of improper plastic management in Bangladesh. In this study, the route of plastic waste production and current plastic waste management system in Bangladesh have been reviewed extensively. It emerges that no technical and improved methods are adapted in the plastic management system. A set of the sustainable plastic management system has been proposed along with the challenges that would emerge during the implementation these strategies. Successful execution of the proposed systems would enhance the quality of plastic waste management in Bangladesh and offers enormous energy from waste.

    Wood, Matthew D; Bostrom, Ann; Bridges, Todd; Linkov, Igor

    2012-08-01

    Risk managers are increasingly interested in incorporating stakeholder beliefs and other human factors into the planning process. Effective risk assessment and management requires understanding perceptions and beliefs of involved stakeholders, and how these beliefs give rise to actions that influence risk management decisions. Formal analyses of risk manager and stakeholder cognitions represent an important first step. Techniques for diagramming stakeholder mental models provide one tool for risk managers to better understand stakeholder beliefs and perceptions concerning risk, and to leverage this new understanding in developing risk management strategies. This article reviews three methodologies for assessing and diagramming stakeholder mental models--decision-analysis-based mental modeling, concept mapping, and semantic web analysis--and assesses them with regard to their ability to address risk manager needs. © 2012 Society for Risk Analysis.

  5. Perioperative Management of Diabetes: A Review

    Directory of Open Access Journals (Sweden)

    Md Nazmul Kayes

    2014-07-01

    Full Text Available Diabetes increases the requirements of surgery as well as perioperative morbidity and mortality. Careful preoperative evaluation and treatment of cardiac and renal diseases, intensive intraoperative and postoperative management are essential to optimize the best outcome. Stress hyperglycemia in response to surgery, osmotic diuresis and hypoinsulinemia can lead to life threatening complications like ketoacidosis or hyperglycemic hyperosmolar syndrome. Wound healing is impaired by hyperglycemia and chance of postoperative wound infection is more in diabetics. Therefore aseptic precautions must be taken. Adequate insulin, glucose, fluid and electrolytes should be provided for good metabolic control. Though some current study reveals that oral hypoglycemic agents can be used for the effective management of perioperative diabetes; the adverse effects of newly introduced agents need more clinical observations. Subcutaneous administration of insulin as in Sliding Scale may be a less preferable method, because of unreliable absorption and unpredictable blood glucose. Intravenous administration of rapid onset soluble (short acting insulin as in Alberti (GIK regimen, is safe and effective method controlling perioperative hyperglycemia. Patient with type 1 diabetes needs frequent monitoring of glucose, electrolytes and acid-base balance as chance of high hyperglycemia and ketoacidosis is more. In case of emergency surgery assessment for diabetic ketoacidosis (DKA and meticulous management is essential. Postoperative pain and hyperglycemia should be treated carefully to avoid complications.

    Directory of Open Access Journals (Sweden)

    J Y Chinda

    2013-01-01

    Full Text Available Background: Paediatric head injury (HI is the single most common cause of death and permanent disability in children world over, and this is increasingly becoming worrisome in our society because of increased risks and proneness to road traffic accidents on our highways and streets. The study set to determine causes and management of HI among children in our society. Patients and Methods: A retrospective review of all children aged 0-15 years with traumatic head injury (THIs who were managed at the University of Maiduguri Teaching Hospital between July, 2006 and August, 2008. Results: A total of 45 children with THIs presented to the casualty unit of the hospital; 30 (66.7% were boys and 15 (33.3% were girls. Three (6.7% children were less than 1 year of age, 21 (46.7% were between 1 years and 6 years while 16 (35.6% and 5 (11.0% were aged 7-11 years and 12-15 years respectively. Thirty six (80.0% of the children were pedestrians, 6 (13.4% fell from a height, while 2 (4.4% and 1 (2.2% were as a result of home accident and assault, respectively. Twenty one patients (46.7% had mild HI, while 53.3% had moderate to severe category. Forty one (91.1% of children were managed as in-patients, mostly (95.1% by conservative non-operative management, while 4 (8.9% were treated on the out-patient basis. The mortality rate was 17.8%. Conclusion: H1 among children is of a great concern, because of its incremental magnitude, due to increasing child labour and interstate religious discipleship among children, with attendant high mortality and permanent disabilities. Necessary laws and legislations should be formulated and implemented with organized campaigns and public enlightenment to prevent and mitigate this menace.

CINAHL, MEDLINE, PsycINFO, Proquest ABI/Inform, Cochrane Library and Joanne Briggs Institute Library were searched for empirical studies published between 2002-May 2014. The review was informed by the approach of Whittemore and Knafl. Findings were extracted, critically examined and grouped into themes. Forty-four papers met the inclusion criteria. Several antecedents influence conflict and choice of conflict management style including individual characteristics, contextual factors and interpersonal conditions. Sources most frequently identified include lack of emotional intelligence, certain personality traits, poor work environment, role ambiguity, lack of support and poor communication. Very few published interventions were found. By synthesizing the knowledge and identifying antecedents, this review offers evidence to support recommendations on managing and mitigating conflict. As inevitable as conflict is, it is the responsibility of everyone to increase their own awareness, accountability and active participation in understanding conflict and minimizing it. Future research should investigate the testing of interventions to minimize these antecedents and, subsequently, reduce conflict. © 2016 John Wiley & Sons Ltd.

    Regulations on radioactive waste disposal are now in urgent need due to our increasing consumption of electric power from nuclear origin. It is set forth that actually applying the regulations to evaluate the license application of new repositories for interim storage and final disposal of High-Level Waste and Low-Level Waste before the year of 2000. In the mean time, it is expected to establish the basis for the decision on issuing the license. The license review procedure can be very complicated, because too many factors must be taken into consideration. For the time being, licensing review is as much an art as it is a science. The authority usually faces three major problems; (1) the availability of domain expert, (2) maintaining of high quality and consistent reviews, and (3) the documentation of the review process. However, to maintain a more efficient, accurate, and systematic review procedure, and at the same time to reduce costs, the Artificial Intelligence (AI) techniques may be used. An expert system is designed as a radioactive waste management licensing review aid for the staff those are in charge of the license application. Tasks such as completeness checking, functional areas of review distribution, participation confirmation, knowledge acquisition, review comment collection, weighting calculation, and degree of satisfaction are considered. In this paper we will discuss the development of the radioactive waste management licensing review assistant

    Bam earthquake was the most catastrophic natural disasters in recent years. The aim of this study was to review different aspects of crisis management during and after the catastrophic earthquake in Bam City, Iran. Data needed for this systematic review were collected through searching PubMed, EMBASE and SID databases, for the period from 2003 to 2011. Keywords included earthquake, Iran and Bam earthquake. The data were summarized and were analyzed using Content Analysis. Out of 422 articles, 25 articles were included in the study. Crisis Management aspects and existing pitfalls were classified into seven categories including planning and organization, human resource management, management of logistics, international humanitarian aids, field performance of the military and security forces, health and medical service provision, and information management. Positive aspects and major pitfalls of crisis management have been introduced in all the mentioned categories. The available evidence indicated poor crisis management during Bam earthquake that resulted in aggravating the losses as well as diminishing the effect of interventions. Thus, concerning the importance of different aspects of the crisis management and the high prevalence of disasters in Iran, the observed vulnerability in disaster management process should be addressed.

    The hypothesis that exposure to ionizing radiation accelerates the aging process has been actively investigated at ABCC-RERF since 1958, when longitudinal cohort studies of the Adult Health Study (AHS) and the Life Span Study (LSS) were initiated. In their 1975 overall review of aging studies related to the atomic bomb (A-bomb) survivors, Finch and Beebe concluded that while most studies had shown no correlation between aging and radiation exposure, they had not involved the large numbers of subjects required to provide strong evidence for or against the hypothesis. Extending LSS mortality data up to 1978 did not alter the earlier conclusion that any observed life-shortening was associated primarily with cancer induction rather than with any nonspecific cause. The results of aging studies conducted during the intervening 15 years using data from the same populations are reviewed in the present paper. Using clinical, epidemiological, and laboratory techniques, a broad spectrum of aging parameters have been studied, such as postmortem morphological changes, tests of functional capacity, physical tests and measurements, laboratory tests, tissue changes, and morbidity. With respect to the aging process, the overall results have not been consistent and are generally thought to show no relation to radiation exposure. Although some preliminary results suggest a possible radiation-induced increase in atherosclerotic diseases and acceleration of aging in the T-cell-related immune system, further study is necessary to confirm these findings. In the future, applying the latest gerontological study techniques to data collected from subjects exposed 45 years ago to A-bomb radiation at relatively young ages will present a new body of data relevant to the study of late radiation effects.

  16. Nuclear waste management: A review of issues

    International Nuclear Information System (INIS)

    Angino, E.E.

    1985-01-01

    The subject of radioactive waste management and burial is a subject that raises strong emotional and political issues and generates sharp technical differences of opinion. The overall problem can be subdivided into the three major categories of (1) credibility and emotionalism, (2) technology, and (3) nuclear waste isolation and containment. An area of concern desperately in need of attention is that of proper public education on all aspects of the high-level radioactive-waste (rad-waste) burial problem. A major problem related to the rad-waste issue is the apparent lack of an official, all-encompassing U.S. policy for nuclear waste management, burial, isolation, and regulation. It is clear from all past technical reports that disposal of rad wastes in an appropriate geologic horizon is the best ultimate solution to the waste problem. After 25 y of dealing with the high-level radioactive waste problem, the difficulty is that no proposed plan has to date been tested properly. It is this indecision and reaction that has contributed in no small way to the public perception of inability to solve the problem. One major change that has occurred in the last few years was the enactment of the Nuclear Waste Policy Act of 1982. This act mandates deadlines, guidelines, and state involvement. It is time that strong differences of opinions be reconciled. One must get on with the difficult job of selecting the best means of isolating and burying these wastes before the task becomes impossible

  17. Do Aging Factors Influence the Clinical Presentation and Management of Chronic Rhinosinusitis?

    Renteria, Axel E; Mfuna Endam, Leandra; Desrosiers, Martin

    2017-04-01

    Objective/Hypothesis Chronic rhinosinusitis (CRS) is a complex inflammatory disease of the upper respiratory airways resulting from the dysregulation of immunity and epithelial defenses. More recently, the contribution of an altered nasal microbiome to the development of CRS has also been proposed. However, the impact of aging on the development of CRS has been long overlooked. Here we propose, in a hypothesis piece, that aging can influence the physiopathology of CRS and its subsequent management in an elderly population. Data Sources We summarize the recent literature findings supporting that elderly patients with CRS could be a distinct population from those with adult CRS and might require different or adjunct therapeutic approaches. Methods Review of recent literature of the effect of aging and its possible effects in CRS using 3 different databases. Conclusions Age-dependent decrease in the levels of the S100 family proteins involved in epithelial proliferation, repair, and defenses combined with chronic inflammation might lead to an increased risk of abnormal microbial colonization and loss of microbiota diversity. Ultimately, these changes could have the potential to alter the physiopathology of CRS in the elderly. Implications Unlike in adults, in whom CRS T h 2-skewed responses with eosinophilia are thought to play a critical role, in aging populations, a microbiome and epithelial barrier dysfunctions may instead be the pivotal agents of disease development and persistence. This supports that therapies for elderly patients may require a different management or additional targeted therapies to control the disease. Prospective studies, however, are necessary to validate this concept.

    Hevia Ruperez, F.

    2000-01-01

    The aim of this paper is to review relevant objectives and aspects of the Maintenance Evaluation and Improvement Programmes for Nuclear Power Plant Life Management. Recent experience shows that current maintenance practice often fails to directly address long-term degradation that affects singular plant components and equipment populations. Instead, delayed attention to the consequences makes good Life Management unfeasible. This has brought about the need for specific Maintenance Evaluation and Improvement Programmes to adjust to the basic objective of Life Management which is to protect against, mitigate and/or monitor ageing that affects the safe, profitable life of the facility. The paper analyses the methodologies used, incidents during their application and the main conclusions reached from the implementation of these programmes in Spanish nuclear power plants. Special attention is paid to recommended solutions for improving the efficiency of the utility's contributions, its leadership in task development and integration, and its interfaces with organisations specialised in providing services that support Life Management Programmes. The coexistence of these and other similar maintenance programmes make it necessary to integrate tasks to optimise effort and tools. The paper analyses the guidelines to be considered when integrating these Programmes with other maintenance optimisation programmes (economy and feasibility, RCM) and with tasks derived from the application of Maintenance Rule regulatory requirements. Lastly, the paper reports on the state of these Maintenance Evaluation and Improvement Programmes, their development, what prospects they have, and the Industry's initiative and actions concerning the matter.

    2012-11-08

    Elderly care practice and its management together with policy and research play a crucial role in responding to increasing challenges in institutional care for elderly people. Successful dialogue between these is necessary. The purpose of this systematic literature review is to compare how institutional elderly care management research meets the care challenges currently emphasized in international long-term care policy documents. This paper was based on a systematic literature review. After screening 1971 abstracts using inclusion/exclusion criteria, 58 refereed articles published between 2000 and 2010 remained for analysis. The articles were analyzed using theory-based content analysis by comparing the results to the framework based on analysis of international long-term care management policy documents. The current challenges of long-term care management identified from policy documents were Integrated Care Management, Productivity Management, Quality Management, Workforce Management and ICT Management. The research on institutional elderly care management responded somewhat to the challenges mentioned in policy documents. However, some of the challenges were studied broadly and some were paid only minor attention. Further, only few studies focused on the core items of challenges addressed in policy documents. Institutional care management research needs to focus more on challenges in integrated care, productivity, ICT and division of labor. Managers, researchers and policy-makers should assume more active collaborative roles in processes of research, policymaking and policy implementation. In addition managers' and policymakers' scientific literacy needs to be enhanced.

    Knowledge management comprises the strategies and methods employed to generate and leverage knowledge within an organization. This report outlines the activities within the Division of Pharmacometrics at the US FDA to effectively manage knowledge with the ultimate goal of improving drug development and advancing public health. The infrastructure required for pharmacometric knowledge management includes provisions for data standards, queryable databases, libraries of modeling tools, archiving of analysis results and reporting templates for effective communication. Two examples of knowledge management systems developed within the Division of Pharmacometrics are used to illustrate these principles. The benefits of sound knowledge management include increased productivity, allowing reviewers to focus on research questions spanning new drug applications, such as improved trial design and biomarker development. The future of knowledge management depends on the collaboration between the FDA and industry to implement data and model standards to enhance sharing and dissemination of knowledge.

  5. Examining End-of-Life Case Management: Systematic Review

    2014-01-01

    Full Text Available Case management was initiated in the 1970s to reduce care discontinuity. A literature review focused on end-of-life (EOL case management identified 17 research articles, with content analysis revealing two themes: (a seeking to determine or establish the value of EOL case management and (b identifying ways to improve EOL case management. The evidence, although limited, suggests that EOL case management is helpful to dying individuals and their families. Research is needed to more clearly illustrate its usefulness or outcomes and the extent of need for it and actual availability. Among other benefits, EOL case management may help reduce hospital utilization, a major concern with the high cost of hospital-based care and the increased desire for home-based EOL care.

    Purpose - The purpose of this study is to describe the characteristics of management and leadership competence of health-care leaders and managers, especially in the hospital environment. Health-care leaders and managers in this study were both nursing and physician managers. Competence was assessed by evaluating the knowledge, skills, attitudes and abilities that enable management and leadership tasks. Design/methodology/approach - A systematic literature review was performed to find articles that identify and describe the characteristics of management and leadership competence. Searches of electronic databases were conducted using set criteria for article selection. Altogether, 13 papers underwent an inductive content analysis. Findings - The characteristics of management and leadership competence were categorized into the following groups: health-care-context-related, operational and general. Research limitations/implications - One limitation of the study is that only 13 articles were found in the literature regarding the characteristics of management and leadership competence. However, the search terms were relevant, and the search process was endorsed by an information specialist. The study findings imply the need to shift away from the individual approach to leadership and management competence. Management and leadership need to be assessed more frequently from a holistic perspective, and not merely on the basis of position in the organizational hierarchy or of profession in health care. Originality/value - The authors' evaluation of the characteristics of management and leadership competence without a concentrated profession-based approach is original.

  7. Integrated Water Resources Management: A Global Review

    2011-12-01

    The diversity of water resources endowments and the societal arrangements to use, manage, and govern water makes defining a single paradigm or lens through which to define, prioritize and evaluate interventions in the water sector particularly challenging. Integrated Water Resources Management (IWRM) emerged as the dominant intervention paradigm for water sector interventions in the early 1990s. Since then, while many successful implementations of IWRM have been demonstrated at the local, basin, national and trans-national scales, IWRM has also been severely criticized by the global water community as "having a dubious record that has never been comprehensively analyzed", "curiously ambiguous", and "ineffective at best and counterproductive at worst". Does IWRM hold together as a coherent paradigm or is it a convenient buzzword to describe a diverse collection of water sector interventions? We analyzed 184 case study summaries of IWRM interventions on the Global Water Partnership (GWP) website. The case studies were assessed to find the nature, scale, objectives and outcomes of IWRM. The analysis does not suggest any coherence in IWRM as a paradigm - but does indicate distinct regional trends in IWRM. First, IWRM was done at very different scales in different regions. In Africa two-thirds of the IWRM interventions involved creating national or transnational organizations. In contrast, in Asia and South America, almost two-thirds were watershed, basin, or local body initiatives. Second, IWRM interventions involved very different types of activities in different regions. In Africa and Europe, IWRM entailed creation of policy documents, basin plans and institution building. In contrast, in Asia and Latin America the interventions were much more likely to entail new technology, infrastructure or watershed measures. In Australia, economic measures, new laws and enforcement mechanisms were more commonly used than anywhere else.

    The management of radioactive waste in Nigeria from early 1960 to date is reviewed. As in many developing countries, waste management in Nigeria has been shown to be ineffective. The factors that are responsible for this ineffectiveness are identified and discussed. The steps being taken by and the opportunities available to the newly established Nigerian Nuclear Regulatory Authority towards addressing this problem of ineffectiveness are discussed. The efforts of this newly set up body towards managing the resultant radioactive wastes that will be generated during the use of a reactor and an accelerator that will soon be commissioned in Nigeria are also mentioned. Likely ways of further addressing the problems militating against waste management in developing countries are suggested. (review)

    Groin pain is a common symptom in athletes, particularly in sports requiring sudden changes in speed and direction and those involving kicking. Despite a high prevalence of groin pain in this patient cohort, the diagnosis and management of the underlying pathological processes remains a challenge for surgeons and radiologists alike. The aim of this paper is to review the imaging findings and management of the common pathological processes which produce groin pain in athletes. The anatomy of the groin region will be defined as a basis for further discussion. The common pathological processes underlying groin pain such as adductor dysfunction, rectus abdominus injury, osteitis pubis, and femuro-acetabular impingement will then be reviewed and correlating radiological imaging findings presented. Current management options will also be considered. This paper will aid surgeons and radiologists in navigating the challenging diagnostic and management dilemma of groin pain in athletes.

    We reviewed the literature on standard case management (SCM), intensive case management (ICM), assertive community treatment (ACT), and critical time intervention (CTI) for homeless adults. We searched databases for peer-reviewed English articles published from 1985 to 2011 and found 21 randomized controlled trials or quasi-experimental studies comparing case management to other services. We found little evidence for the effectiveness of ICM. SCM improved housing stability, reduced substance use, and removed employment barriers for substance users. ACT improved housing stability and was cost-effective for mentally ill and dually diagnosed persons. CTI showed promise for housing, psychopathology, and substance use and was cost-effective for mentally ill persons. More research is needed on how case management can most effectively support rapid-rehousing approaches to homelessness. PMID:23947309

  11. Mechanisms of the anorexia of aging-a review.

    2015-08-01

    Many, even healthy, older people fail to adequately regulate food intake and experience loss of weight. Aging-associated changes in the regulation of appetite and the lack of hunger have been termed as the anorexia of aging. The etiology of the anorexia of aging is multi-factorial and includes a combination of physiological changes associated with aging (decline in smell and taste, reduced central and peripheral drive to eat, delayed gastric emptying), pathological conditions (depression, dementia, somatic diseases, medications and iatrogenic interventions, oral-health status), and social factors (poverty, loneliness). However, exact mechanisms of the anorexia of aging remain to be elucidated. Many neurobiological mechanisms may be secondary to age-related changes in body composition and not associated with anorexia per se. Therefore, further studies on pathophysiological mechanisms of the anorexia of aging should employ accurate measurement of body fat and lean mass. The anorexia of aging is associated with protein-energy malnutrition, sarcopenia, frailty, functional deterioration, morbidity, and mortality. Since this symptom can lead to dramatic consequences, early identification and effective interventions are needed. One of the most important goals in the geriatric care is to optimize nutritional status of the elderly.

    During operation of nuclear power plants, the quality of systems, structures and components may change as a result of ageing (conceptional ageing, technological ageing or physical ageing), which will affect the system quality. Ageing management is necessary to ensure safety and availability throughout the life of the systems. This necessitates a systematic, integrative and knowledge-based approach. Systems, structures and components are grouped according to their relevance for meeting the set goals. Ageing mangement should be process-oriented and should be integrated in the organisational procedure in cooperation with the safety manager. The procedure should follow the PDCA principle (plan - do - check - act). The data, documents, knowledge and evaluations required for ageing management are part of the knowledge base of the nuclear power station and are updated regularly. The efficiency of ageing management must be reassessed at regular intervals. (orig.)

    2012-01-01

    Background Elderly care practice and its management together with policy and research play a crucial role in responding to increasing challenges in institutional care for elderly people. Successful dialogue between these is necessary. The purpose of this systematic literature review is to compare how institutional elderly care management research meets the care challenges currently emphasized in international long-term care policy documents. Methods This paper was based on a systematic literature review. After screening 1971 abstracts using inclusion/exclusion criteria, 58 refereed articles published between 2000 and 2010 remained for analysis. The articles were analyzed using theory-based content analysis by comparing the results to the framework based on analysis of international long-term care management policy documents. Results The current challenges of long-term care management identified from policy documents were Integrated Care Management, Productivity Management, Quality Management, Workforce Management and ICT Management. The research on institutional elderly care management responded somewhat to the challenges mentioned in policy documents. However, some of the challenges were studied broadly and some were paid only minor attention. Further, only few studies focused on the core items of challenges addressed in policy documents. Conclusions Institutional care management research needs to focus more on challenges in integrated care, productivity, ICT and division of labor. Managers, researchers and policy-makers should assume more active collaborative roles in processes of research, policymaking and policy implementation. In addition managers’ and policymakers’ scientific literacy needs to be enhanced. PMID:23137416

  4. Coeliac disease: review of diagnosis and management.

    Science.gov (United States)

    Walker, Marjorie M; Ludvigsson, Jonas F; Sanders, David S

    2017-08-21

    Coeliac disease is an immune-mediated systemic disease triggered by exposure to gluten, and manifested by small intestinal enteropathy and gastrointestinal and extra-intestinal symptoms. Recent guidelines recommend a concerted use of clear definitions of the disease. In Australia, the most recent estimated prevalence is 1.2% in adult men (1:86) and 1.9% in adult women (1:52). Active case finding is appropriate to diagnose coeliac disease in high risk groups. Diagnosis of coeliac disease is important to prevent nutritional deficiency and long term risk of gastrointestinal malignancy. The diagnosis of coeliac disease depends on clinico-pathological correlation: history, presence of antitransglutaminase antibodies, and characteristic histological features on duodenal biopsy (when the patient is on a gluten-containing diet). Human leucocyte antigen class II haplotypes DQ2 or DQ8 are found in nearly all patients with coeliac disease, but are highly prevalent in the general population at large (56% in Australia) and testing can only exclude coeliac disease for individuals with non-permissive haplotypes. Adhering to a gluten free diet allows duodenal mucosal healing and alleviates symptoms. Patients should be followed up with a yearly review of dietary adherence and a health check. Non-coeliac gluten or wheat protein sensitivity is a syndrome characterised by both gastrointestinal and extra-intestinal symptoms related to the ingestion of gluten and possibly other wheat proteins in people who do not have coeliac disease or wheat allergy recognised by diagnostic tests.

  5. Management of long term sickness absence: a systematic realist review.

    2012-09-01

    The increasing impact and costs of long term sickness absence have been well documented. However, the diversity and complexity of interventions and of the contexts in which these take place makes a traditional review problematic. Therefore, we undertook a systematic realist review to identify the dominant programme theories underlying best practice, to assess the evidence for these theories, and to throw light on important enabling or disabling contextual factors. A search of the scholarly literature from 1950 to 2011 identified 5,576 articles, of which 269 formed the basis of the review. We found that the dominant programme theories in relation to effective management related to: early intervention or referral by employers; having proactive organisational procedures; good communication and cooperation between stakeholders; and workplace-based occupational rehabilitation. Significant contextual factors were identified as the level of support for interventions from top management, the size and structure of the organisation, the level of financial and organisational investment in the management of long-term sickness absence, and the quality of relationships between managers and staff. Consequently, those with responsibility for managing absence should bear in mind the contextual factors that are likely to have an impact on interventions, and do what they can to ensure stakeholders have at least a mutual understanding (if not a common purpose) in relation to their perceptions of interventions, goals, culture and practice in the management of long term sickness absence.

    Health care managers find their work increasingly difficult, due in part to rapid environmental change that plagues organizational life. Management practices and attitudes that may have been appropriate in previous eras are ineffective today. A study was conducted among managers in the Ministry of Health, State of Bahrain, seeking information about current trends in the macro or external environment that affect the Ministry of Health, as well as internal environmental pressures that may be similar or different. This article provides a clear picture of the context in which managers perform their work and offers recommendations for coping with change in dynamic, complex organizations.

  9. Reviewing the economic efficiency of disaster risk management

    2013-04-01

    There is a lot of rhetoric suggesting that disaster risk management (DRM) pays, yet surprisingly little in the way of hard facts. Cost-benefit analysis (CBA) is one major tool that can provide quantitative information about the prioritization of disaster risk management (DRM) (and climate adaptation) based on economic principles. Yet, on a global scale, there has been surprisingly little robust evidence on the economic efficiency and benefits of risk management measures. This review shows that for the limited evidence reported the economic case for DRM across a range of hazards is strong and that the benefits of investing in DRM outweigh the costs of doing so, on average, by about four times the cost in terms of avoided and reduced losses. Most studies using a CBA approach focus on structural DRM and most information has been made available on physical flood prevention. There have been some limited studies on preparedness and risk financing. The global evidence base is limited and estimates appear not very solid, and overall, in line with the conclusion of the recent IPCC SREX report, there is limited evidence and medium agreement across the literature. Some of the factors behind the limited robustness are inherent to CBA more widely: these challenges comprise the inability to price intangibles, evaluating strategies rather than single projects, difficulties in assessing softer rather than infrastructure-related options, choices regarding a proper discount rate, lack of accounting for the distribution of benefits and costs and difficulties with assessing nonmarket values such as those related to health, the environment, or public goods. Although techniques exist to address some of these challenges, they are not very likely to easily go away. Other challenges associated specifically with DRM, such as the need and difficulty to undertake risk -based analysis can be overcome, and there have been manuals and reports providing a way forward. In an age of austerity, cost

    The European Union of Medical Specialists, founded in 1958, is the largest and oldest european medical organization. It includes 39 member states (of the European Union and others), and represents a total of 1.600.000 medical specialists. The main objective of the UEMS is to influence european healthcare politics by promoting the interests of the european medical specialists, establishing high standards in practice and training, as well as continuing medical education and professional development, and guaranteeing quality in specialist practice. The UEMS is developing several projects to face current and future challenges related to surgical training, education, acreditation, revalidation and professional development: i.- First, the UEMS is developing homogeneous requisites for European Training (ETRs), ii.- To manage the quality control process of the ETRs and evaluation of the organization, the UEMS has created the Council of european specialized medial evaluations (CESMA), iii.- The UEMS has been greatly involved in the acreditation process of training centres in all of Europe, iv.- in relation to continuing medical education, the European Accreditation Council for Continuing Medical Education (EACCME) is the main project of the UEMS for the accreditation of educational events and v.- the UEMS has established the Network of Accredited Clinical Skills Centres of Europe (UEMS-NASCE), that facilitates the accreditation and cooperation of training centres in Europe. In conclusion, with the great support of National Surgical Societies of the UEMS and the Surgery Section a series of solid projects have been established to support the professional development of the collective in Europe. This process constitutes a continuous effort that is very gratifying, with the aim to set the standards for a brilliant future for surgery students and specialized surgeons. Copyright © 2017.

    The process and safety system of a nuclear power plant must achieve the reliability/availability target throughout the plant life or for extended plant life. It is therefore necessary to assess the trend of component or system ageing and to take preventive measures so that ageing effect can be counter balanced. In this paper a mathematical model has been established to predict ageing effect and to find out time dependent inspection or test interval to upgrade the system availability. (author). 5 figs

  17. Aging in bacteria, immortality or not-a critical review.

    Gómez, José M G

    2010-12-01

    Bacteria were traditionally thought to have a symmetrical binary fission without a clear distinction between soma and germ-line, being thus considered as immortal biological entities. Yet it has been recently described that bacteria also undergo replicative aging (RA). That is, they exhibit finite replicative abilities under good conditions to growth. The apparently initial indistinguishability of sibling cells after cytokinesis is broken. After division, the daughter cell that inherits the "old" pole present in the "mother cell" progressively exhibits a decline in its proliferative capacity with increasing cell pole age. This is a clear hallmark and phenotypic manifestation of a bona fide RA phenomenon in toto. While the exact molecular mechanism(s) underlying to this lost of replicative potential are not yet fully understood, the "old pole cell" is considered as an aging parent that in a repeatedly manner is able to produce rejuvenated offspring which inherit a resetting of the biological clock. On the order hand, bacteria exhibit in addition to this "mandatory" RA the dubbed conditional senescence (CS). CS is defined as a decline in cellular viability observed in arrested-growing bacteria populations, a phenomenon apparently not related to RA under growing active conditions. To understand bacterial aging, it is necessary to put it within the sociality-multicellularity framework. This is a new conceptual paradigm that expresses the natural reality of the bacterial world. From this more ecological perspective these bacterial aging phenomena probably should represent an insurance/bethedging anticipative survival strategy. This is underpinned in a self-generation of an appropriate level of populational phenotypic diversity. That is, bacterial aging could be considered a communitarian adaptive response to cope with different environmental stresses and threats. I have highlighted the necessity to construct an integrative conceptual framework to achieve a unified view

    Summary The ability to assess bone age accurately is important and allows to diagnose the patient correctly and to plan orthodontic treatment appropriately. The aim of the work is to present views of different authors on the subject of using cephalometric images to determine bone age and its significance for conducting appropriate orthodontic treatment. Publications from the PubMed medical database were analyzed. Search criteria: bone age assessment, CVM method. Ultimately, 36 papers out of 1354 publications were selected. The research of many authors confirms the usefulness of various methods using cephalometric images to assess skeletal age. Currently, the CVM method devised by Baccetti et al. is the most frequently mentioned one in literature. It seems that bone age assessment methods based on evaluating the morphological structure of the cervical vertebrae in cephalometric images can clearly differentiate skeletal maturity in children regardless of their race or sex. Bearing in mind the constant technological progress in medicine and stomatology, bone age assessment methods need to be perfected in order to alleviate their impact on the patient as much as possible.

    2016-04-01

    Childhood asthma is a growing health concern. Asthma is the most common chronic illness of childhood and a leading cause of emergency room visits, hospitalizations, and school absenteeism. School nurses play a valuable role in asthma management. The purpose of this integrative review is to examine barriers to asthma management for school nurses in the school setting. Findings revealed multiple barriers school nurses encounter in managing asthma. Six themes emerged that included lack of resources and support, insufficient time, communication challenges, limited knowledge, and lack of awareness of school nurses' expertise. Students, parents, primary care physicians, school administration, staff, and school nurses themselves all play a role in constructing barriers to asthma management. There is a need for school nurses and school nurse leaders to focus efforts to develop strategies to overcome barriers to ensure evidence-based, best practice management of asthma in the school setting. © The Author(s) 2015.

    Knowledge has been used as a resource for intelligent and effective action planning in organizations. Interest in research on knowledge management processes has intensified in different areas. A systematic literature review was accomplished, based on the question: what are the contributions of Brazilian and international journal publications on knowledge management in health? The sample totaled 32 items that complied with the inclusion criteria. The results showed that 78% of journals that published on the theme are international, 77% of researchers work in higher education and 65% have a Ph.D. The texts gave rise to five thematic categories, mainly: development of knowledge management systems in health (37.5%), discussion of knowledge management application in health (28.1%) and nurses' function in knowledge management (18.7%).

    Artificial intelligence methods in combination with the latest technologies, including medical devices, mobile computing, and sensor technologies, have the potential to enable the creation and delivery of better management services to deal with chronic diseases. One of the most lethal and prevalent chronic diseases is diabetes mellitus, which is characterized by dysfunction of glucose homeostasis. The objective of this paper is to review recent efforts to use artificial intelligence techniques to assist in the management of diabetes, along with the associated challenges. A review of the literature was conducted using PubMed and related bibliographic resources. Analyses of the literature from 2010 to 2018 yielded 1849 pertinent articles, of which we selected 141 for detailed review. We propose a functional taxonomy for diabetes management and artificial intelligence. Additionally, a detailed analysis of each subject category was performed using related key outcomes. This approach revealed that the experiments and studies reviewed yielded encouraging results. We obtained evidence of an acceleration of research activity aimed at developing artificial intelligence-powered tools for prediction and prevention of complications associated with diabetes. Our results indicate that artificial intelligence methods are being progressively established as suitable for use in clinical daily practice, as well as for the self-management of diabetes. Consequently, these methods provide powerful tools for improving patients' quality of life. ©Ivan Contreras, Josep Vehi.

    1992-01-01

    This Phase I Nuclear Plant Aging Research (NPAR) study examines the aging phenomena associated with BWR control and rod drive mechanisms (CRDMs) and assesses the merits of various methods of ''imaging'' this aging. Information for this study was acquired from (1) the results of a special CRDM aging questionnaire distributed to each US BWR utility, (2) a first-of-its-kind workshop held to discuss CRDM aging and maintenance concerns, (3) an analysis of the Nuclear Plant Reliability Data System (NPRDS) failure cases attributed to the control rod drive (CRD) system, and (4) personal information exchange with nuclear industry CRDM maintenance experts. The report documenting the findings of this research, NUREG-5699, will be published this year. Nearly 23% of the NPRDS CRD system component failure reports were attributed to the CRDM. The CRDM components most often requiring replacement due to aging are the Graphitar seals. The predominant causes of aging for these seals are mechanical wear and thermal embrittlement. More than 59% of the NPRDS CRD system failure reports were attributed to components that comprise the hydraulic control unit (HCU). The predominant HCU components experiencing the effects of service wear and aging are value seals, discs, seats, stems, packing, and diaphragms

    Wilson, Bridget H; Nelson, Jessica

    2015-04-01

    Sickle cell disease (SCD) pain continues to emerge in adolescents. More than 98,000 individuals are believed to have SCD in the United States. In fact, 1 in 500 Black infants will be affected by SCD. Identifying standards of care for this unique population can improve pain management and treatment. A significant effect of vaso-occlusive crisis is a decrease in the quality of life in children. Therefore, pain management is multidimensional and includes pharmacologic, physical, and psychological strategies. A review of the literature was conducted to identify best practices regarding pain management in adolescents with sickle cell anemia. Key words such as pain, pain management, adolescent sickle cell anemia, and acute sickle cell pain were entered into databases to reveal qualitative and quantitative studies from 2009 to the present. Many of the research articles identified poor SCD pain management. Studies showed that acute SCD pain management is essential and should be evaluated and robustly managed to achieve optimum pain relief for patients. Acute SCD pain usually occurs as a result of vaso-occlusive crisis. Untreated acute SCD pain can result in morbidity and mortality in adolescents. Nursing knowledge is critical to reducing the stigma and improving management of SCD pain. Nurses play a vital role in the introduction of evidence-based practice within the clinical setting. In an effort to educate nurses and other health care professionals about SCD, this article is a literature review of studies concerning SCD and pain management in emergency rooms.

    1989-01-01

    Over recent years the electric power generating community has acknowledged the importance of the aging process on plant safety and availability. To cope with time-dependent degradation phenomena that can affect active as well as passive components and lead to unacceptable, unanticipated failures requires research into the mechanisms of the aging process, advances in predictive methods for assessing the aging impact on risk and availability, and a better understanding of power plant operations so that strategies for defending against this pervasive stress can be developed. This paper discusses current research advances and presents a framework to aid in the systematic integration of these three needs. It also discusses current research in the aging effect on electric components. As such it is anchored to research being conducted at Brookhaven National Laboratory in the areas of plant aging, life extension, reliability, performance indication, and risk assessment. (orig.)

    2018-03-01

    Full Text Available Metabolic epilepsy is a metabolic abnormality which is associated with an increased risk of epilepsy development in affected individuals. Commonly used antiepileptic drugs are typically ineffective against metabolic epilepsy as they do not address its root cause. Presently, there is no review available which summarizes all the treatment options for metabolic epilepsy. Thus, we systematically reviewed literature which reported on the treatment, therapy and management of metabolic epilepsy from four databases, namely PubMed, Springer, Scopus and ScienceDirect. After applying our inclusion and exclusion criteria as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA guidelines, we reviewed a total of 43 articles. Based on the reviewed articles, we summarized the methods used for the treatment, therapy and management of metabolic epilepsy. These methods were tailored to address the root causes of the metabolic disturbances rather than targeting the epilepsy phenotype alone. Diet modification and dietary supplementation, alone or in combination with antiepileptic drugs, are used in tackling the different types of metabolic epilepsy. Identification, treatment, therapy and management of the underlying metabolic derangements can improve behavior, cognitive function and reduce seizure frequency and/or severity in patients.

    1986-01-01

    Managing a nuclear plant might well be the toughest industrial job in the United States today. Everyday, nuclear plant managers must deal with the twin concerns of producing megawatts reliably and protecting the safety of the plant personnel and the public. A nuclear plant manager must possess a combination of special technical and managerial skills to do his job well. He also must be supported fully and actively by his utility's corporate management and organization. For more than five years, INPO teams have observed nuclear plant performance and on-site management. For nearly three years, we have been looking at corporate management support. The authors review the results of these plant and corporate evaluations from a management standpoint. More specifically, they look at two areas: One, how and why INPO evaluates plant performance and plant and corporate management, and two, what INPO evaluators have been during these evaluations. Or, to put it another way, what are the characteristics of good management at the best plants we've visited, and what are the areas for improvement that INPO sees most often

This is no more apparent than in high care residential health and aged care services, where health professionals are increasingly required to provide care for older people with multifocal and complex healthcare needs. This paper describes one of the projects undertaken as part of the Joanna Briggs Institute Commonwealth Department of Health and Ageing Clinical Aged Care Fellowship program from February 2005 to June 2005. This purpose of this particular project was twofold. First it sought to improve the local practice in the prevention and management of constipation and that this practice was performed according to the best available evidence. Second to use the Joanna Briggs Institute Practical Application of Clinical Guidance (PACES) program to implement a process of audit and feedback as a strategy to improve practice. The project was designed to link in with the facility's existing quality improvement program and better practice continence management project. The project was conducted over 6 months and was divided into six stages involving the identification of evidence-based standards of care, an initial audit to determine appropriate sample size, a clinical audit across the facility, planning of the implementation process, implementation of the action plan and re-audit to assess practice change. Overall, the results were extremely positive and demonstrated a real improvement in practice relating to constipation in the project facility. This success, however, needs to be seen in the context of the benefits of having the support of senior management, an existing quality improvement and continence management better practice project, and a culture of clinical review. Although there will always be more work to be done, the success of this project can be

    Full Text Available The construction industry is well known as a highly risk prone industry owing to the complexity of its activities and dynamic project environments generating an atmosphere of risks that must be taken into consideration in the decision process. For this reason, we have developed this treatise to elucidate the fundamentals of risk management through a concise new proposal of literature review for risk management in construction. Our explanation of this is venture is that over the years, this area has been acknowledged as a crucial process in the business institutions and the most discussed subject among experts and researchers in the construction sector. We have tried in this report to present the most recent studies considering the impossibility to present all definitions of the concept of risk. This study is mainly a literature review; it looks at the literature relating to the concept of risk, risk management in construction as well as methods used in construction industry.

    The purpose of this study was to review evaluation studies of nursing management information systems (NMISs) and their outcome measures to examine system effectiveness. For the systematic review, a literature search of the PubMed, CINAHL, Embase, and Cochrane Library databases was conducted to retrieve original articles published between 1970 and 2014. Medical Subject Headings (MeSH) terms included informatics, medical informatics, nursing informatics, medical informatics application, and management information systems for information systems and evaluation studies and nursing evaluation research for evaluation research. Additionally, manag(*) and admin(*), and nurs(*) were combined. Title, abstract, and full-text reviews were completed by two reviewers. And then, year, author, type of management system, study purpose, study design, data source, system users, study subjects, and outcomes were extracted from the selected articles. The quality and risk of bias of the studies that were finally selected were assessed with the Risk of Bias Assessment Tool for Non-randomized Studies (RoBANS) criteria. Out of the 2,257 retrieved articles, a total of six articles were selected. These included two scheduling programs, two nursing cost-related programs, and two patient care management programs. For the outcome measurements, usefulness, time saving, satisfaction, cost, attitude, usability, data quality/completeness/accuracy, and personnel work patterns were included. User satisfaction, time saving, and usefulness mostly showed positive findings. The study results suggest that NMISs were effective in time saving and useful in nursing care. Because there was a lack of quality in the reviewed studies, well-designed research, such as randomized controlled trials, should be conducted to more objectively evaluate the effectiveness of NMISs.

    Objectives The aims of the study were to investigate discrepancies between general practitioners' paper medication orders and pharmacy-prepared electronic medication administration charts, back-up paper charts and dose-administration aids, as well as delays between prescribing, charting and administration, at a 90-bed residential aged care facility that used a hybrid paper-electronic medication management system. Methods A cross-sectional audit of medication orders, medication charts and dose-administration aids was performed to identify discrepancies. In addition, a retrospective audit was performed of delays between prescribing and availability of an updated electronic medication administration chart. Medication administration records were reviewed retrospectively to determine whether discrepancies and delays led to medication administration errors. Results Medication records for 88 residents (mean age 86 years) were audited. Residents were prescribed a median of eight regular medicines (interquartile range 5-12). One hundred and twenty-five discrepancies were identified. Forty-seven discrepancies, affecting 21 (24%) residents, led to a medication administration error. The most common discrepancies were medicine omission (44.0%) and extra medicine (19.2%). Delays from when medicines were prescribed to when they appeared on the electronic medication administration chart ranged from 18min to 98h. On nine occasions (for 10% of residents) the delay contributed to missed doses, usually antibiotics. Conclusion Medication discrepancies and delays were common. Improved systems for managing medication orders and charts are needed. What is known about the topic? Hybrid paper-electronic medication management systems, in which prescribers' orders are transcribed into an electronic system by pharmacy technicians and pharmacists to create medication administration charts, are increasingly replacing paper-based medication management systems in Australian residential aged care

  1. Understanding and Managing Aging of Spent Nuclear Fuel and Facility Components in Wet Storage

    International Nuclear Information System (INIS)

    Johnson, A. B.

    2007-01-01

    Storage of nuclear fuel after it has been discharged from reactors has become the leading spent fuel management option. Many storage facilities are being required to operate longer than originally anticipated. Aging is a term that has emerged to focus attention on the consequences of extended operation on systems, structures, and components that comprise the storage facilities. The key to mitigation of age-related degradation in storage facilities is to implement effective strategies to understand and manage aging of the facility materials. A systematic approach to preclude serious effects of age-related degradation is addressed in this paper, directed principally to smaller facilities (test and research reactors). The first need is to assess the materials that comprise the facility and the environments that they are subject to. Access to historical data on facility design, fabrication, and operation can facilitate assessment of expected materials performance. Methods to assess the current condition of facility materials are summarized in the paper. Each facility needs an aging management plan to define the scope of the management program, involving identification of the materials that need specific actions to manage age-related degradation. For each material identified, one or more aging management programs are developed and become part of the plan Several national and international organizations have invested in development of comprehensive and systematic approaches to aging management. A method developed by the US Nuclear Regulatory Commission is recommended as a concise template to organize measures to effectively manage age-related degradation of storage facility materials, including the scope of inspection, surveillance, and maintenance that is needed to assure successful operation of the facility over its required life. Important to effective aging management is a staff that is alert for evidence of materials degradation and committed to carry out the aging

    The purpose of this scoping review of literature is to explore the types of computer-based systems used for self-management of chronic disease, the goals and success of these systems, the value added by technology integration and the target audience for these systems. Technology is changing the way health care is provided and the way that individuals manage their health. Individuals with chronic diseases are now able to use computer-based systems to self-manage their health. These systems have the ability to remind users of daily activities, and to help them recognise when symptoms are worsening and intervention is indicated. However, there are many questions about the types of systems available, the goals of these systems and the success with which individuals with chronic illness are using them. This is a scoping review in which the Cumulative Index of Nursing and Allied Health Literature, PubMed and IEEE Xplore databases were searched. A total of 303 articles were reviewed, 89 articles were read in-depth and 30 were included in the scoping review. The Substitution, Augmentation, Modification, Redefinition model was used to evaluate the value added by the technology integration. Research on technology for self-management was conducted in 13 countries. Data analysis identified five kinds of platforms on which the systems were based, some systems were focused on a specific disease management processes, others were not. For individuals to effectively use systems to maintain maximum wellness, the systems must have a strong component of self-management and provide the user with meaningful information regarding their health states. Clinicians should choose systems for their clients based on the design, components and goals of the systems. © 2016 John Wiley & Sons Ltd.

    Regulations on radioactive waste disposal are now in urgent need due to our increasing consumption of electric power from nuclear origin. It is set forth that actually applying the regulations to evaluate the license application of new repositories for interim storage and final disposal fo High-Level Waste and Low-Level Waste before the year of 2000. In the mean time, it is expected to establish the basis for the decision on issuing the license. The license review procedure can be very complicated because too many factors must be taken into consideration. However, to maintain a more efficient, accurate, and systematic review procedure, and at the same time to reduce costs, the Artificial Intelligence (AI) techniques may be used. An expert system is designed as a radioactive waste management licensing review aid for the staff those are in charge of the license application. Tasks such as completeness checking, functional areas of review distribution, participation confirmation, knowledge acquisition, review comment collection, weighting calculation, and degree of satisfaction are considered. In this paper the authors will discuss the development of the radioactive waste management licensing review assistant

    Hyperthyroidism has important implications for pregnancy, affecting both mother and fetus. Appropriate maternal and fetal management iscritical to avoiding adverse pregnancy outcomes and requires a multidisciplinary approach. To describe maternal diagnosis and management of hyperthyroidism, across all stages of pregnancy. In addition, to review clinical signs of fetal thyroid dysfunction due to maternal Graves disease and discuss management considerations. Review of published articles on PubMed and guidelines by recognized governing organizations regarding the diagnostic and management considerations for hyperthyroidism in pregnancy, from preconception to the postpartum period. Diagnosis of maternal hyperthyroidism involves both clinical symptoms and laboratory findings. Antithyroid medications are the mainstay of therapy, with trimester-specific pregnancy goals. Hyperthyroidism due to Graves disease has important diagnostic and management considerations for the fetus and neonate. Hyperthyroidism in pregnancy affects mother, fetus, and neonate. Interpretation of thyroid tests and understanding the appropriate use of antithyroid drugs are fundamental. Proper education of physicians providing care to women with hyperthyroidism is essential and starts before pregnancy. Postpartum follow-up is an essential part of the care. A systematic approach to management will ensure optimal pregnancy outcomes.

    Over recent years the electric power generating community has acknowledged the importance of the aging process on plant safety and availability. To cope with time-dependent degradation phenomena that can affect active as well as passive components and lead to unacceptable, unanticipated failures requires research into the mechanisms of the aging process, advances in predictive methods for assessing the aging impact on risk and availability, and a better understanding of power plant operations so that strategies for defending against this pervasive stress can be developed. This paper discusses current research advances and presents a framework to aid in the systematic integration of these three needs. As such it is anchored to research being conducted at Brookhaven National laboratory in the areas of plant aging, life extension, reliability, performance indication, and risk assessment

    In preparation for PLGS life extension, NBPN spent considerable effort to evaluate the impact of ageing and to develop ageing management processes to maintain the required safety functions for extended operation. These were based on INPO AP-913. Recently, the CNSC has been developing Canadian ageing management guidelines in line with the IAEA approach. In response, NBPN plans to document how current PLGS processes meet the new CNSC guidelines and to identify any areas for improvement. Best practices from utilities that have retrofitted IAEA guidelines and PLGS experience in applying risk-based methods for ageing management will be used to implement improvements. (author)

    2017-01-01

    Background In today’s society, stress is more and more often a cause of disease. This makes stress management an important target of behavior change programs. Gamification has been suggested as one way to support health behavior change. However, it remains unclear to which extend available gamification techniques are integrated in stress management apps, and if their occurrence is linked to the use of elements from behavior change theory. Objective The aim of this study was to investigate the use of gamification techniques in stress management apps and the cooccurrence of these techniques with evidence-based stress management methods and behavior change techniques. Methods A total of 62 stress management apps from the Google Play Store were reviewed on their inclusion of 17 gamification techniques, 15 stress management methods, and 26 behavior change techniques. For this purpose, an extended taxonomy of gamification techniques was constructed and applied by 2 trained, independent raters. Results Interrater-reliability was high, with agreement coefficient (AC)=.97. Results show an average of 0.5 gamification techniques for the tested apps and reveal no correlations between the use of gamification techniques and behavior change techniques (r=.17, P=.20), or stress management methods (r=.14, P=.26). Conclusions This leads to the conclusion that designers of stress management apps do not use gamification techniques to influence the user’s behaviors and reactions. Moreover, app designers do not exploit the potential of combining gamification techniques with behavior change theory. PMID:28592397

    The first calf paper, published in the May 1919 issue of the Journal of Dairy Science (JDS), described factors affecting birth body weight of different breeds of calves. Other studies were done on nonmilk ingredients, growth charts were developed, and early weaning was followed to conserve milk fed to calves. Calf papers did not report use of statistics to control or record variation or to determine whether treatment means were different. Many experiments were more observational than comparative. Typically fewer than 5 calves, and sometimes 1 or 2 calves, were used per treatment. During the next 20 yr, calf studies increased and included colostrum feeding, milk and milk replacer feeding, minerals and vitamins, and fats and oils. Many concepts fundamental to current knowledge and understanding of digestion, rumen development, and milk replacer formulation were developed during this period. In addition, the concept of using antibiotic growth promoters in dairy calf diets was first evaluated and developed during the 1950s. During the 20-yr period of January 1957 through December 1976, a large number of universities in the United States and 1 in Canada contributed almost 150 papers on a variety of calf-related topics. These topics included genetics, physiology of the calf, review of calf immunity, antibiotic feeding, and milk replacer ingredients. This became the golden era of calf rumen development studies, which also engendered studies of calf starter rations and ingredients. A classic review of management, feeding, and housing studies summarized research related to calf feeding and management systems up to that point with an emphasis on maintaining calf growth and health while reducing labor and feed costs. It was also during this period that metric measurements replaced English units. In the 20-yr period from 1977 to 1996, more than 400 articles on calf nutrition and management were published in JDS. With the growing research interest in calves, a paper outlining

    To establish validity of a clinical leadership framework for aged care middle managers (The Aged care Clinical Leadership Qualities Framework). Middle managers in aged care have responsibility not only for organisational governance also and operational management but also quality service delivery. There is a need to better define clinical leadership abilities in aged care middle managers, in order to optimise their positional authority to lead others to achieve quality outcomes. A Delphi method. Sixty-nine experts in aged care were recruited, representing rural, remote and metropolitan community and residential aged care settings. Panellists were asked to rate the proposed framework in terms of the relevance and importance of each leadership quality using four-point Likert scales, and to provide comments. Three rounds of consultation were conducted. The number and corresponding percentage of the relevance and importance rating for each quality was calculated for each consultation round, as well as mean scores. Consensus was determined to be reached when a percentage score reached 70% or greater. Twenty-three panellists completed all three rounds of consultation. Following the three rounds of consultation, the acceptability and face validity of the framework was confirmed. The study confirmed the framework as useful in identifying leadership requirements for middle managers in Australian aged care settings. The framework is the first validated framework of clinical leadership attributes for middle managers in aged care and offers an initial step forward in clarifying the aged care middle manager role. The framework provides clarity in the breadth of role expectations for the middle managers and can be used to inform an aged care specific leadership program development, individuals' and organisations' performance and development processes; and policy and guidelines about the types of activities required of middle managers in aged care. © 2014 John Wiley & Sons Ltd.

    This study compared the effectiveness of stress management programs in dental education by systematic review of the literature. The number of studies concerning stress management programs for dental students is limited compared with studies discussing sources of stress. Several types of programs for stress management have been reported, and differ in their duration, content, and outcomes. Two main strategies have been used to help stressed students, ie, decreasing the number of stressors and increasing the ability to cope with stress. The first strategy includes several components, such as reducing fear of failure and workload pressure due to examinations and requirements. The second strategy includes coping techniques, such as deep breathing exercises. Although positive effects have been reported for most of the programs, these have mainly been evaluated using subjective self-report measures. There is a need for more research to identify the most effective stress management program. PMID:24904226

    The gynecologist's role in the management of rheumatic patients is complex: it includes the prevention of damage caused by drugs, the counseling about contraception to avoid pregnancy while taking teratogen drugs, the scheduling of pregnancy during the quiescent phase of the specific disease, the replacement of teratogen drugs and a competent management of the pregnancy. The task is carried out as part of a multidisciplinary team with a focus on the differential diagnosis between specific complications of pregnancy and the complications of the rheumatic disease. This is the right way to allow a conscious reproduction, with reduced risks and acceptable maternal-fetal outcomes, to this kind of patients considered at high risk.

    Vaillant, Ludovic; Bataille, Céline

    2012-01-01

    This article proposes a review of past and current ICRP publications dealing with the management of radon exposures. Its main objective is to identify and discuss the driving factors that have been used by the Commission during the last 50 years so as to better appreciate current issues regarding radon exposure management. The analysis shows that major evolutions took place in very recent years. As far as the management of radon exposures is concerned, ICRP recommended, until ICRP Publication 103 (ICRP 2007 ICRP Publication 103; Ann. ICRP 37), to use action levels and to consider only exposures above these levels. The Commission has reviewed its approach and now proposes to manage any radon exposure through the application of the optimisation principle and associated reference levels. As far as the assessment of the radon risk is concerned, it appears that the successive changes made by ICRP did not have a strong impact on the values of radon gas concentration recommended as action levels either in dwellings or in workplaces. The major change occurred in late 2009 with the publication of the ICRP Statement on Radon, which acknowledged that the radon risk has been underestimated by a factor of 2, thus inducing a major revision of radon reference levels.

    The report describes ageing studies of nuclear power plants and research programmes on plant life extension in foreign countries. Ageing studies are aimed to ascertain that the availability and safety of components and structures can be maintained throughout the plant lifetime. In life extension programmes the purpose is to evaluate the technical and economical possibilities to extend the plant lifetime beyond the originally planned operation period, without reducing the plant safety. The main emphasis of the report is put on the ageing and life extension programmes in the United States. Besides the U.S. studies, research on plant life extension possibilities conducted in France and Japan are also described. Examples of studies performed in other nuclear energy producing countries are given. These examples are mainly related to the development of maintenance programmes and techniques

    The PLiM/PLEx Program applied to the Cernavoda NPP has the goal of ensuring the lifetime target of the plant and its extension in conditions of a continuous, secure and reliable operation by fulfilling at the same time the general licensing requirements as established by the regulation authority CNCAN. The aging management is, according to the organization model, a systematic process implying the following activities specific to the operation: - Planning: Coordination of the aging management activities; - Exploitation: Controlling the aging mechanisms; - Testing: Detection and evaluation of the aging effects; - Maintenance: Controlling the aging effects. All these are interdependent with specific activities in INR Pitesti, related to the research and development which are key elements for controlling effectively the aging process. The model of organizing the aging management developed in this work is applied to the Cernavoda NPP Unit 1

    Malignant struma ovarii is an extremely rare ovarian tumour containing malignant thyroid carcinoma within differentiated thyroid tissue, as the predominant tissue type. Surgery for suspected ovarian tumour and incidental pathological diagnosis is the most common presentation. Evidence supporting any particular approach to the clinical management of this condition is limited, mainly consisting of case reports, small series or pathological case series. There is no randomised evidence for postoperative management in view of the rarity of this condition. The opinion is divided between conservative management versus total thyroidectomy and radio-iodine ablation. We carried out a retrospective review of our series with focus on postoperative management of this rare condition. A review of existing literature was also carried out. Six patients with a median age of 52 years presented with various symptoms of abdominal pain, pressure or menstrual problems. After the initial gynaecological resection and specialised pathology review, they were subsequently treated with total thyroidectomy and administration of radioactive iodine. All of these six patients are in remission at a median follow up of 60 months. We favour aggressive postoperative management with total thyroidectomy and radioactive iodine, and long-term follow up of these patients.

This was done by conducting a literature review in the four acknowledged databases Web of Science, Scopus, MEDLINE, and Springer, and consequently by evaluating the findings of the relevant studies. The findings show that physical activities, such as walking and aerobic exercises, music therapy, adherence to Mediterranean diet, or solving crosswords, seem to be very promising lifestyle intervention tools. The results indicate that non-pharmacological lifestyle intervention activities should be intense and possibly done simultaneously in order to be effective in the prevention of cognitive decline. In addition, more longitudinal randomized controlled trials are needed in order to discover the most effective types and the duration of these intervention activities in the prevention of cognitive decline, typical of aging population groups.

    Full Text Available This paper is one of the few studies to review the empirical literature on strategic management tools and techniques usage. There are many techniques, tools and methods, models, frameworks, approaches and methodologies, available to support strategic managers in decision making. They are developed and designed to support managers in all stages of strategic management process to achieve better performance. Management schools provide knowledge of these tools. But their use in organizations should be seen in practice‑based context. Consequently, some questions arise: Do they use these strategic tools and techniques in their workplace? Which strategic tools and techniques are used more in organizations? To answer these questions we have made a review of empirical studies using textual narrative synthesis method. Initially, this study presents a tabulation with a summary of empirical research for the period 1990–2015. The included studies are organized clustering them by enterprise size and sector and by country level development. A synopsis of the ten most used strategic tools and techniques worldwide resulted as follows: SWOT analysis, benchmarking, PEST analysis, “what if” analysis, vision and mission statements, Porter’s five forces analysis, business financial analysis, key success factors analysis, cost‑benefit analysis and customer satisfaction.

  12. Ethical Risk Management Education in Engineering: A Systematic Review.

    2017-04-01

    Risk management is certainly one of the most important professional responsibilities of an engineer. As such, this activity needs to be combined with complex ethical reflections, and this requirement should therefore be explicitly integrated in engineering education. In this article, we analyse how this nexus between ethics and risk management is expressed in the engineering education research literature. It was done by reviewing 135 articles published between 1980 and March 1, 2016. These articles have been selected from 21 major journals that specialize in engineering education, engineering ethics and ethics education. Our review suggests that risk management is mostly used as an anecdote or an example when addressing ethics issues in engineering education. Further, it is perceived as an ethical duty or requirement, achieved through rational and technical methods. However, a small number of publications do offer some critical analyses of ethics education in engineering and their implications for ethical risk and safety management. Therefore, we argue in this article that the link between risk management and ethics should be further developed in engineering education in order to promote the progressive change toward more socially and environmentally responsible engineering practices. Several research trends and issues are also identified and discussed in order to support the engineering education community in this project.

    2010-06-01

    The objective was to identify definitions and/or explanations of the term self-management in educative programs that aim its development. The authors also aimed to describe the educative plans and results of the educative programs analyzed. As a methodology we used integrative review, with 15 published articles (2002 the 2007). The inclusion criteria was: the occurrence of the term self-management; the existence of an educative program for the development of self-management; to be related to the area of the health of the adult. Self-management means the improvement or acquisition of abilities to solve problems in biological, social and affective scopes. The review pointed to different educational methodologies. However, it also showed the predominance of traditional methods, with conceptual contents and of physiopathological nature. The learning was evaluated as favorable, with warns in relation to the application in different populations and contexts and to the increase of costs of the educative intervention. It was concluded that research has evidenced the importance of the education for self-management, but lacked in strength for not relating the biopsychosocial demands of the chronic patient and for not describing in detail the teaching and evaluation methodologies employed.

  14. An Overview of Ageing Management and Refurbishment of Research Reactors at Trombay

    Energy Technology Data Exchange (ETDEWEB)

    Three nuclear research reactors have been in operation at Bhabha Atomic Research Centre, Mumbai, India. India has a rich experience of about 120 research reactor operating years including ageing management. A well structured programme is in force for plant life management, refurbishment and upgrading reactors in operation. Apsara, commissioned in August 1956, was the first research reactor. Apsara is a 1 MW{sub th} swimming pool type of reactor with a movable core loaded with enriched uranium fuel and immersed in demineralized light water pool, which serves as coolant, moderator and reflector besides providing radiation shielding. Apsara was shut down during May 2009 for partial decommissioning and upgrading to a 2 MW reactor with several safety upgrades, e.g. a LEU based reactor core with higher neutron flux, a new reactor building meeting seismic qualification criteria and two independent shutdown devices. Cirus, a 40 MW{sub th} tank type reactor utilizing heavy water as moderator, graphite as reflector, demineralized light water as primary coolant and natural uranium metal as fuel; has been in operation since 1960. After about three decade of operation, the availability factor started declining mainly due to outage of equipment exhibiting signs of ageing. After ageing studies and performance review, refurbishment requirements were identified. A programme for refurbishment was drawn that included safety upgrades like civil repairs to the emergency storage reservoir to meet seismic qualification criteria and a new iodine removal system for better efficiency. The reactor was shut down during 1997 for execution of this refurbishment programme. After completion of refurbishment, the reactor was brought back into operation during 2003. It has completed about seven years of safe operation after refurbishment with a significant increase in availability factor from 70% to about 90%. The reactor was permanently shut down during December 2010. The reactor core was unloaded

    2014-12-15

    Solid waste management is a key aspect of the environmental management of establishments belonging to the hospitality sector. In this study, we reviewed literature in this area, examining the current status of waste management for the hospitality sector, in general, with a focus on food waste management in particular. We specifically examined the for-profit subdivision of the hospitality sector, comprising primarily of hotels and restaurants. An account is given of the causes of the different types of waste encountered in this sector and what strategies may be used to reduce them. These strategies are further highlighted in terms of initiatives and practices which are already being implemented around the world to facilitate sustainable waste management. We also recommended a general waste management procedure to be followed by properties of the hospitality sector and described how waste mapping, an innovative yet simple strategy, can significantly reduce the waste generation of a hotel. Generally, we found that not many scholarly publications are available in this area of research. More studies need to be carried out on the implementation of sustainable waste management for the hospitality industry in different parts of the world and the challenges and opportunities involved.

  18. Evaluating participation in water resource management: A review

    Science.gov (United States)

    Carr, G.; BlöSchl, G.; Loucks, D. P.

    2012-11-01

    Key documents such as the European Water Framework Directive and the U.S. Clean Water Act state that public and stakeholder participation in water resource management is required. Participation aims to enhance resource management and involve individuals and groups in a democratic way. Evaluation of participatory programs and projects is necessary to assess whether these objectives are being achieved and to identify how participatory programs and projects can be improved. The different methods of evaluation can be classified into three groups: (i) process evaluation assesses the quality of participation process, for example, whether it is legitimate and promotes equal power between participants, (ii) intermediary outcome evaluation assesses the achievement of mainly nontangible outcomes, such as trust and communication, as well as short- to medium-term tangible outcomes, such as agreements and institutional change, and (iii) resource management outcome evaluation assesses the achievement of changes in resource management, such as water quality improvements. Process evaluation forms a major component of the literature but can rarely indicate whether a participation program improves water resource management. Resource management outcome evaluation is challenging because resource changes often emerge beyond the typical period covered by the evaluation and because changes cannot always be clearly related to participation activities. Intermediary outcome evaluation has been given less attention than process evaluation but can identify some real achievements and side benefits that emerge through participation. This review suggests that intermediary outcome evaluation should play a more important role in evaluating participation in water resource management.

    Radiation therapy is a major therapeutic modality in the management of cancer patients. Over 60% of these patients receive radiotherapy at some point during their course of treatment and over 90% will develop skin reactions after therapy. Problematic wound healing in radiation-damaged tissue constitutes a major surgical difficulty and despite all efforts, irradiated skin remains a therapeutic challenge. This review provides an overview of the fundamental principles of radiation therapy with regards to the wound healing in normal and irradiated skin. Furthermore, it presents techniques that describe how to prevent and manage skin side effects as well as prospects that may improve cutaneous wound repair in general and in irradiated skin.

    The aim of this paper is to examine the state of knowledge management research in supply chain management from three standpoints, methodological approach, supply chain management area, and knowledge management processes. Design/methodology/approach: To achieve this, a systematic review is conducted over the period 2000-2014 on the basis of a qualitative content analysis. Findings: Major results showed that knowledge management can be viewed as a leverage mechanism for: (i) supply chain integration; (ii) the enhancement of intra and inter-relations across the supply chain; (iii) supply chain strategy alignment; and (iv) the reinforcement of knowledge transfer in product development. Some supply chain management areas such as reverse logistics, inventory management, forecasting/demand planning, outsourcing, and risk management have been explored only to some extent. Furthermore, knowledge transfer is being studied in the majority of the articles, mainly by both case study and survey approach; mathematical models and simulation techniques are used in very limited articles. Findings concerning theoretical perspectives and managerial issues are also described. Research limitations/implications: The limitation of our study encompasses the aspects of search period (2000-2014), selection of search databases (Web of Science and SCOPUS and language selection (English). Practical implications: The exhibition of the KM processes within the SC context may help practitioners and managers interested in implementing KM initiatives to replicate the methodologies in order to increase the possibilities of a successful KM adoption. Originality/value: The systematic review will contribute to the understanding of the present state of research in the knowledge management theory, with focus on the supply chain, as there are no state-of-knowledge studies that report a systematic literature review approach.

    2007-01-01

    The diagnosis of juvenile spondyloarthritis (JSA) is rarely entertained in young children who present with back and leg pain. We present a case of a 6-year-old male who presented with a 3-year history of severe back and leg pain and a positive Gower's sign, and was given a presumed diagnosis of muscular dystrophy. Presenting serologic evaluation included a mildly elevated sedimentation rate and C-reactive protein (CRP). Computed tomography of the pelvis demonstrated large erosions affecting both sacro-iliac joints. Despite the unusually young age of this patient, ankylosing spondylitis seemed the most plausible diagnosis. Following rheumatological evaluation and treatment for JSA, he showed significant clinical improvement. His disease, however, has not entirely remitted with signs of enthesitis at the Achilles tendon and knees. We present this case to illustrate that JSA could account for symptoms at an early age and not considering it could lead to multiple medical visits and diagnoses. To our knowledge, based on a search of the World literature, this would appear to be the youngest case of JSA reported with demonstrable severe sacroiliitis. (orig.)

  11. U.S.-NPAR approach to managing aging in operating nuclear power plants

    International Nuclear Information System (INIS)

    Bosnak, R.; Vagins, M.; Vora, J.

    1991-01-01

    Aging degradation in operating nuclear power plants must be managed to prevent safety margins from eroding below the levels provided in plant design bases. The NPAR program and other aging-related programs conducted under the auspices of the US NRC Office of Nuclear Regulatory Research are developing needed technical bases and guidance for understanding and managing aging in operating nuclear power plants (NPP) of all ages. Results from these programs, together with relevant information developed by industry are implemented through various ongoing NRC and industry programs. The aging management process central to these efforts consists of three key element: 1) selection and prioritization of components, systems, and structures (CSS) in which aging must be managed, 2) understanding of the relevant aging mechanisms and rates of degradation processes in these CSS, and 3) managing degradation through effective inspection, surveillance, condition monitoring, trending, preventive and corrective maintenance, and mitigation. This paper provides a historical perspective on the aging related research programs sponsored by the Office of U.S. Nuclear Regulatory Research. Also, briefly described are the major element of the NPAR program and its status and results or accomplishments. In the process the authors emphasize the need for total industry commitment and participation in implementing programs for understanding and managing aging in operating nuclear power plants. 'Aging' is universal in nature. No industrial complex including NPP should be considered immune from its effects. For NPP aging is manageable its ti symptoms are recognized and predicted, if it is monitored and appropriate steps are taken for timely mitigation of age-related degradation. (author)

    Franck, Linél; Molyneux, Natalie; Parkinson, Lynne

    2016-06-01

    A systematic review was undertaken of studies reporting interventions for reducing social isolation and depression in older people receiving aged care services (community or residential). Gray literature and relevant electronic databases were systematically searched for studies published in English between January 2009 and December 2013. Two reviewers independently screened studies for selection using predetermined inclusion and exclusion criteria and independently completed methodological quality review at study level. Studies of poor methodological quality were excluded. Data were extracted at study level by one reviewer and independently checked by a second reviewer, using a standardized form. The results across studies were qualitatively synthesized with outcomes described and summarized at last follow-up. Although the original objective was to review rural studies, no intervention studies based in rural areas met criteria for inclusion in the review, and only urban studies could be reviewed. Of 403 articles, six articles representing five studies with moderate-to-low risk of bias were included for review. All study participants were older adults ranging in age from 77 to 86 years. All studies had small sample sizes, ranging from 26 to 113 participants. Three of the five included intervention studies successfully reduced social isolation; one also successfully reduced depression. Only one intervention, group-based reminiscence therapy, was reported as successful in reducing both social isolation and depression in older people within an urban aged care setting. More research is needed to explore transferability of interventions across different aged care settings and into rural areas.

    2015-09-01

    Hospital management has experienced significant progress with the evolution of the Romanian health system reform, it has made strides in terms of resource allocation and cost control, new systems for classification, evaluation and monitoring (DRGs, SIUI, CaPeSaRo) were implemented, some taken from other countries and adapted to local conditions, but not always integrated with the other components and sometimes incompletely implemented and developed. This material does not offer definite solutions to current problems. It only briefly addresses the main aspects of hospital activity, and points out some failures with whom hospital managers are presently faced. Once the problems are identified it creates prerequisites for solving them, it opens channels of research and development of new methodologies or correlation of the existing deficient workflows that can be corrected.

    Kang-Yi, Christina D; Adams, Danielle R

    2017-01-01

    This systematic review aimed to (1) identify and summarize empirical studies on youth with behavioral health disorders aging out of foster care and (2) address implications for behavioral health policy, research, and practice. We identified previous studies by searching PubMed, PsycINFO, EBSCO, and ISI Citation Indexes and obtaining references from key experts in the child welfare field. A total of 28 full articles published between 1991 and 2014 were reviewed and summarized into the key areas including systems of care, disability type, transition practice area, study methods, study sample, transition outcome measures, study analysis, and study findings. Considering how fast youth who have behavioral health disorders fall through the crack as they exit foster care, one cannot understate the importance of incorporating timely and appropriate transition planning and care coordination for youth who have behavioral health disorders aging out of foster care into the usual case management performed by behavioral health systems and service providers.

    Most component failures stem from effects of one or multiple ageing mechanism(s). Ageing management is one of the most robust measures to prevent failure and to maintain and increase safety of nuclear power plants. Based on Nuclear Safety Guideline on Ageing Management (NS-G-2.12) published by IAEA in 2009, the paper summarizes main ageing management activities required for all stages of life cycle of NPPs, including design, construction/manufacture, commissioning, operation, life extension for long-term operation and decommissioning. Interactive relations of ageing management in successive stages are analyzed. Implementation of the IAEA Guideline in comprehensive way will bring new challenges to design conception, modes of construction, manufacture, commissioning, equipment qualification, O and M, licensing, life extension and decommissioning for NPPs, however, it will be beneficial to enhance nuclear safety level, especially to promote development of nuclear power in China in a safe, reliable, profitable and sustainable way.

    Introducing the new, realistic loyalty pact between employer and employee. The employer-employee relationship is broken, and managers face a seemingly impossible dilemma: the old model of guaranteed long-term employment no longer works in a business environment defined by continuous change, but neither does a system in which every employee acts like a free agent. The solution? Stop thinking of employees as either family or as free agents. Think of them instead as allies. As a manager you want your employees to help transform the company for the future. And your employees want the company to help transform their careers for the long term. But this win-win scenario will happen only if both sides trust each other enough to commit to mutual investment and mutual benefit. Sadly, trust in the business world is hovering at an all-time low. We can rebuild that lost trust with straight talk that recognizes the realities of the modern economy. So, paradoxically, the alliance begins with managers acknowledging that ...

  19. Management review of nuclear material control and accounting systems

    Section 70.58, ''Fundamental Nuclear Material Controls,'' of 10 CFR Part 70, ''Special Nuclear Materials,'' requires, in paragraph 70.58(c), that certain licensees authorized to possess more than one effective kilogram of special nuclear material establish a management system to provide for the development, revision, implementation, and enforcement of nuclear material control and accounting procedures. Such a system must provide for a review of the nuclear material control system at least every 12 months. This guide describes the purpose and scope, personnel qualifications, depth of detail, and procedures that are acceptable to the NRC staff for the management review of nuclear material control systems required under paragraph 70.58(c) of 10 CFR Part 70.

    The formation of a bezoar is a relatively infrequent disorder that affects the gastrointestinal system. Bezoars are mainly classified into four types depending on the material constituting the indigestible mass of the bezoar: phytobezoars, trichobezoars, pharmacobezoars, and lactobezoars. Gastric bezoars often cause ulcerative lesions in the stomach and subsequent bleeding, whereas small intestinal bezoars present with small bowel obstruction and ileus. A number of articles have emphasized the usefulness of Coca-Cola® administration for the dissolution of phytobezoars. However, persimmon phytobezoars may be resistant to such dissolution treatment because of their harder consistency compared to other types of phytobezoars. Better understanding of the etiology and epidemiology of each type of bezoar will facilitate prompt diagnosis and management. Here we provide an overview of the prevalence, classification, predisposing factors, and manifestations of bezoars. Diagnosis and management strategies are also discussed, reviewing mainly our own case series. Recent progress in basic research regarding persimmon phytobezoars is also briefly reviewed. PMID:25901212
