    A plurality of magnetically operated switches are spaced equally in the hollow tube of a control rod actuating mechanism. One side of each switch is connected, via a low resistance, to a corresponding tap of a low resistance voltage divider network consisting of an equivalent number of low resistance sections with the opposite side of each switch connected to a common conducting wire A. To both ends of the voltage dividing network are connected, respectively, conducting wires B and C. Wires A, B, and C are further coupled to a fuel rod position indicator comprising a voltmeter and power source external to the control rod actuating member. The control rod actuating member is adapted to slide in the hollow tube so that switches passing a position facing a magnet secured to the lower end of the actuating member are rendered closed. Hence, the position of the control rod may be read by reading the voltage off the meter.

    1979-05-01

    This paper, which also appears as an Appendix to the final Working Group 4 report, forms part of the overall economic assessment of reprocessing. The indicative national position and illustrative ''phase diagram'' for the United States is presented. The prospective costs of nuclear power are given for four equilibrium modes of LWR operation: once-through, 15% and 25% improved once-through and thermal recycle. For a particular representative choice of fuel cycle parameters the economic cross over at which thermal recycle becomes economic relative to a 15% improved once-through cycle is above 100/lb U 3 O 8 . Thus the US believes that for the next several decades there is no economic incentive for thermal recycle. As a planning guide the US considers that the fast reactor will not become commercialised in the US before the year 2020

    Full Text Available The regional planning is conceived to apply during the period defined for each sectorial plan: It isn’t yet question of inflecting a retrospective effect in according of the results, except when a master plan in submit a revision. In this situation, it would be the principal needs to build indicators. The period of adoption of the urban or regional plans is an obstacle: it is not so easy to set up a method to follow and evaluation for plans working towards for 5 years or less. It’s necessary to also recognize the difficulty in working out with simple and mutual indicators. The spatial representation of the indicators is not simple: all the variables cannot be declined in all scales either on account of the relevance, or on account of the availability of the local data. We’ll describe here the first results of two environmental indicators (the ecological footprint and the global index of quality of life and wellbeing. The ecological footprint confirms the interest to develop a model of dense and compact cities (careful in consumption of space, energy efficiency in particular thanks to public transport… even if it is a no sufficient requirement that the effective ecological footprint does not exceed the limits. The Indicator of environmental quality (IQE presents a France performance of 58 and l’ Ile-de-France of 56. On the other hand, the performance of Indicator of quality of life (IQS Ile-de-France the performance is better (57 than France (55. One thus notes that, when one mobilizes a great number of indicators, the performances of the Ile-de-France approach those of France average. From the point of view of a sustainable development, the quality of life and the quality of ecosystem to appear like objectives cannot be overlooked of all level of territories; regional level take a key position.

  14. Family planning and social position of women.

    Begum, Hasna

    1993-04-01

    This presentation began with at least three biases: (i) Acceptance of a secular approach to the problem of artificially controlling human reproduction; (ii) acceptance of an absolute egalitarian position in matter of choices and applications of family planning methods; and (iii) acceptance of the view that a small family gives women more opportunities to flourish as humans. The conclusion of the presentation is: though in implementing family planning programmes much deviation from the egalitarian principle could be found, in reality the implementation itself does bring about some opportunities for women to enhance their position in society. Undoubtedly the malpractices in family planning programmes cause death and miseries to women. But, until better methods are invented for both male and female sexes to replace the harmful ones and the male members of the society feel equal responsibility in matters of controlling reproduction, women have now no other choice but to accept the lesser evil.

    To achieve long term positive results for endosseous dental implants, three points have to be considered: the osséointegration, the correct indication and the suprastructural planification designed for the spécific type of implant. If the surgery part is done by a different practitioner as the prosthetic part, tight coworking for planning is necessary and the responsibility in each step has to be cleared in advance. The planification in implant cases is divided into three stages: clearing of contraindications, choice of the suprastructure, and the surgery planning. Aids for exact localisation of the implants are presented.

    Yu, Je-Yong; Huh, Hyung; Choi, Myoung-Hwan; Kim, Ji-Ho; Sohn, Dong-Seong

    2008-01-01

    The present paper is related to position sensing means and more particularly, to a magnetic position sensor using a permanent magnet and a compact arrangement of reed switches in a nuclear power plant. The reed switch position transmitter (RSPT) is used as a position indicator for the control rod in commercial nuclear power plants made by ABB-CE. But this position indicator has some problems when directly adopting it to the integral reactor. Its indicating resolution (1-1/2 inch (38.1mm)) is suitable to measure the position of a control rod which is driven by a motor having steps of 3/4 inch (19.05mm). But the Control Element Drive Mechanism (CEDM) for the integral reactor is designed to raise and lower the control rod in steps of 2mm in order to satisfy the design features of the integral reactor which are the soluble boron free operation and the use of a nuclear heating for the reactor start-up. These design features require a CEDM for the integral reactor to have a fine-step movement for a fine reactivity control. Therefore the resolution of the position indicator for the integral reactor should be achieved to sense the position of the control rod more precisely than that of the RSPT of the ABB-CE. This paper adopts seismic resistance reed switches to the position indicator in order to reduce the damages or impacts during the handling of the position indicator and earthquake. The control rod position indicator having a seismic resistance characteristic for the integral reactor was developed on the basis of the RSPT technology identified through the survey

    2005-01-01

    A third generation synchrotron radiation source of energy 2.5 GeV named INDUS-2 at Centre for Advanced Technology (C.A.T), Indore (M.P) is in the advanced stage of construction. Accurate determination and correction of beam closed orbit in INDUS-2 machine within 100 of microns is a very desirable goal. Bench based calibration of Beam Position Indicators (BPI) play a very important and useful role during initial commissioning of electron machines. To precisely measure transverse position of electron beam in the Indus-2 storage ring, 56 Beam Position Indicators (BPI) will be installed in INDUS-2 machine. Out of 56 Beam Position Indicators 40 are of individual type whereas 16 are integrated with dipole vacuum chamber. The Beam Position Indicators are required to be calibrated before they can be installed. The calibration is done to determine electrical offset with respect to defined mechanical centre, to determine displacement sensitivities as well as non linearity's of BPI. Ideally when beam passes through the geometrical center of BPI's, all electrodes should have same signal strength. However due to different capacitance of electrodes and offset and drift in electronics, the electrical centre (mechanical x, y where all electrodes shows same signal strength) differs from mechanical centre of BPI. A fully automatic calibration system has been developed to carry out the calibration of Beam Position Indicators. A calibration software has been developed which has necessary utilities to process and display calibration data and results. This paper describes the calibration results of Indus-2 BPM. (author)

    Assari Arani, Abbas; Atashbar, Tohid; Antoun, Joseph; Bossert, Thomas

    2018-03-01

    Two years after the implementation of the Health Sector Evolution Plan (HSEP), this study evaluated the effects of the plan on health equity indices. The main indices assessed by the study were the Out-of-Pocket (OOP) health expenditures, the Fairness in Financial Contribution (FFC) to the health system index, the index of households' Catastrophic Health Expenditure (CHE) and the headcount ratio of Impoverishing Health Expenditure (IHE). The per capita share of costs for total health services has been decreased. The lowered costs have been more felt in rural areas, generally due to sharp decrease in inpatient costs. Per capita pay for outpatient services is almost constant or has slightly increased. The reform plan has managed to improve households' Catastrophic Health Expenditure (CHE) index from an average of 2.9% before the implementation of the plan to 2.3% after the plan. The Fairness in Financial Contribution (FFC) to the health system index has worsened from 0.79 to 0.76, and the headcount ratio of Impoverishing Health Expenditure (IHE) index deteriorated after the implementation of plan from 0.34 to 0.50. Considerable improvement, in decreasing the burden of catastrophic hospital costs in low income strata which is about 26% relative to the time before the implementation of the plan can be regarded as the main achievement of the plan, whereas the worsening in the headcount ratio of IHE and FFC are the equity bottlenecks of the plan.

    2014-01-01

    In the face of global warming and environmental change, the conventional strategy of resource centralization will not be able to cope with a future of increasingly extreme climate events and related disasters. It may even contribute to inter-regional disparities as a result of these events. To promote sustainable development, this study offers a case study of developmental planning in Chiayi, Taiwan and a review of the relevant literature to propose a framework of social vulnerability indicators at the township level. The proposed framework can not only be used to measure the social vulnerability of individual townships in Chiayi, but also be used to capture the spatial developmental of Chiayi. Seventeen social vulnerability indicators provide information in five dimensions. Owing to limited access to relevant data, the values of only 13 indicators were calculated. By simply summarizing indicators without using weightings and by using zero-mean normalization to standardize the indicators, this study calculates social vulnerability scores for each township. To make social vulnerability indicators more useful, this study performs an overlay analysis of social vulnerability and patterns of risk associated with national disasters. The social vulnerability analysis draws on secondary data for 2012 from Taiwan's National Geographic Information System. The second layer of analysis consists of the flood potential ratings of the Taiwan Water Resources Agency as an index of biophysical vulnerability. The third layer consists of township-level administrative boundaries. Analytical results reveal that four out of the 18 townships in Chiayi not only are vulnerable to large-scale flooding during serious flood events, but also have the highest degree of social vulnerability. Administrative boundaries, on which social vulnerability is based, do not correspond precisely to “cross-administrative boundaries,” which are characteristics of the natural environment.

    Self-perceived class results from directly questioning subjects about his or her social class. The aim of this investigation was to analyse self-perceived class in relation to other indicator variables of socioeconomic level. Data from the 1994 Catalan Health Interview Survey, a cross-sectional survey of a representative sample of the non-institutionalised population of Catalonia was used. We conducted a discriminant analysis to compute the degree of right classification when different socioeconomic variables potentially related to self-perceived class were considered. All subjects who directly answered the questionnaire were included (N = 12,245). With the aim of obtaining the discriminant functions in a group of subjects and to validate it in another one, the subjects were divided into two random samples, containing approximately 75% and 25% of subjects (analysis sample, n = 9,248; and validation sample, n = 2,997). The final function for men and women included level of education, social class (based in occupation) and equivalent income. This function correctly classified 40.9% of the subjects in the analysis sample and 39.2% in the validation sample. Two other functions were selected for men and women separately. In men, the function included level of education, professional category, and family income (39.2% of classification in analysis sample and 37.2% in validation sample). In women, the function (level of education, working status, and equivalent income) correctly classified 40.3% of women in analysis sample whereas the percentage was 38.9% in validation sample. The percentages of right classification were higher for the highest and lowest classes. These results show the utility of a simple variable to self-position within the social scale. Self-perceived class is related to education, income, and working determinants.

  11. Indicators for management of planned outages in nuclear power plants

    International Nuclear Information System (INIS)

    2006-04-01

    The outages considered within the scope of this publication are planned refuelling outages (PWR and BWR nuclear power plants) and planned outages associated with major maintenance, tests and inspections (PHWR and LWGR nuclear power plants). The IAEA has published some valuable reports providing guidance and assistance to operating organizations on outage management. This TECDOC outlines main issues to be considered in outage performance monitoring and provides guidance to operating organizations for the development and implementation of outage programmes which could enhance plant safety, reliability and economics. It also complements the series of reports published by the IAEA on outage management and on previous work related to performance indicators developed for monitoring different areas of plant operation, such as safety, production, reliability and economics. This publication is based upon the information presented at a technical meeting to develop a standardized set of outage indicators for outage optimization, which was organised in Vienna, 6-9 October 2003. At this meeting, case studies and good practices relating to performance indicator utilization in the process of planned outage management were presented and discussed

    1979-01-01

    The efficiency of the process of oil extraction is determined by the effect of a number of interrelated technological indicators. Analytical expression of the interrelationships of the indicators was represented by an econometric model consisting of a system of linear regression equations. The basic advantage of these models is the possibility of calculating in them different, significantly important interrelationships. This makes it possible to correlate all calculations into a single logically noncontradictory balanced system. The developed model of the technological process of oil extraction makes it possible to significantly facilitate calculation and planning of its basic indicators with regard for system and balance requirements, makes it possible to purposefully generate new variants. In this case because of the optimal distribution of the volumes of geological-technical measures, a decrease in the total outlays for their implementation is achieved. Thus for the Berezovskiy field, this saving was R 150,000.

    Full text: The ranking of dose distributions is of importance in several areas such as i) comparing rival treatment plans, ii) comparing iterations in an optimisation routine, and iii) dose-assessment of clinical trial data. This study aimed to investigate the influence of choice of objective function in ranking tumour dose distributions. A series of physical (mean, maximum, minimum, standard deviation of dose) dose-volume histogram (DVH) reduction indices and biologically-based (tumour-control probability - TCP; equivalent uniform dose -EUD) indices were used to rank a series of hypothetical DVHs, as well as DVHs obtained from a series of 18 prostate patients. The distribution in ranking and change in distribution with change in indice parameters were investigated. It is found that not only is the ranking of DVHs dependent on the actual model used to perform the DVH reduction, it is also found to depend on the inherent characteristics of each model (i.e., selected parameters). The adjacent figure shows an example where the 18 prostate patients are ranked (grey-scale from black to white) by EUD when an α value of 0.8 Gy -1 is used in the model. The change of ranking as α varies is evident.

    Nutrient management plans (NMPs) for application of wastewater from concentrated animal feeding operations are designed to meet crop water and nutrient requirements, but implicitly assume that pathogenic microorganisms in the wastewater will be retained and die-off in the root zone. A NMP was implemented on a field plot to test this assumption by monitoring the fate of several fecal indicator microorganisms (Enterococcus, fecal coliforms, somatic coliphage, and total Escherichia coli). When well-water and wastewater were applied to meet measured evapotranspiration (ET), little advective transport of the indicator microorganisms occurred below the root zone and the remaining microorganisms rapidly died-off (within 1 mo). Additional experiments were conducted in the laboratory to better quantify microorganism transport and survival in the field soil. Batch survival experiments revealed much more rapid die-off rates for the bacterial indicator microorganisms in native than in sterilized soil, suggesting that biotic factors controlled survival. Saturated column experiments with packed field soil, demonstrated much greater transport potential for somatic coliphage than bacterial indicators (Enterococcus and total E. coli) and that the retention rates for the indicator microorganisms were not log-linear with depth. A worst case transport scenario of ponded infiltration on a large undistributed soil column from the field was also initiated and indicator microorganisms were not detected in the column outflow or in the soil at a depth of 65 cm. All of these observations support the hypothesis that a NMP at this site will protect groundwater supplies from microorganism contamination, especially when applied water and wastewater meet ET.

    Populations of native and introduced aquatic organisms in the San Francisco Bay/Sacramento-San Joaquin Delta Estuary ("Bay/Delta") have undergone significant declines over the past two decades. Decreasedriver inflow due to drought and increased freshwater diversion have contributed to the decline of atleast some populations. Effective management of the estuary's biological resources requires a sensitive indicatorof the response to freshwater inflow that has ecological significance, can be measured accurately and easily,and could be used as a "policy" variable to set standards for managing freshwater inflow. Positioning of the2% (grams of salt per kilogram of seawater) bottom salinity value along the axis of the estuary was examinedfor this purpose.

    In childhood subluxation of one or both hips may develop rather insidiously. For lack of generally accepted objective methods of assessment, ambiguous interpretations of findings in serial examinations are common. Many subluxations are overlooked during the early stages. In order to overcome such disadvantages, determination of the percentage of migration seems to be a reasonably easy and reliable technique facilitating evaluation of impending dislocation. This investigation was carried out in order to estabilsh norms applicable to patients in the pediatric age interval. The 98th percentile of migration increases with age from 16% in patients < 4 years of age to 24% in patients ≥ 12 years. Higher figures represent subluxation. If the migration exceeds 80% a manifest luxation is present. A difference in migration between the two hips larger than 12% indicates abnormality calling for clinical and radiologic follow-up.

    Purpose: In intensity-modulated radiation therapy (IMRT) planning, reducing the pencil-beam size may lead to a significant improvement in dose conformity, but also increase the time needed for the dose calculation and plan optimization. The authors develop and evaluate a postoptimization refinement (POpR) method, which makes fine adjustments to the multileaf collimator (MLC) leaf positions after plan optimization, enhancing the spatial precision and improving the plan quality without a significant impact on the computational burden. Methods: The authors’ POpR method is implemented using a commercial treatment planning system based on direct aperture optimization. After an IMRT plan is optimized using pencil beams with regular pencil-beam step size, a greedy search is conducted by looping through all of the involved MLC leaves to see if moving the MLC leaf in or out by half of a pencil-beam step size will improve the objective function value. The half-sized pencil beams, which are used for updating dose distribution in the greedy search, are derived from the existing full-sized pencil beams without need for further pencil-beam dose calculations. A benchmark phantom case and a head-and-neck (HN) case are studied for testing the authors’ POpR method. Results: Using a benchmark phantom and a HN case, the authors have verified that their POpR method can be an efficient technique in the IMRT planning process. Effectiveness of POpR is confirmed by noting significant improvements in objective function values. Dosimetric benefits of POpR are comparable to those of using a finer pencil-beam size from the optimization start, but with far less computation and time. Conclusions: The POpR is a feasible and practical method to significantly improve IMRT-plan quality without compromising the planning efficiency.

    The Reed Switch Position Transmitter (RSPT) is used as a position indicator for the control rod in commercial nuclear power plants made by ABB-CE. But this position indicator has some problems when directly adopting it to the integral reactor. The Control Element Drive Mechanism (CEDM) for the integral reactor is designed to raise and lower the control rod in steps of 2mm in order to satisfy the design features of the integral reactor which are the soluble boron free operation and the use of a nuclear heating for the reactor start-up. Therefore the resolution of the position indicator for the integral reactor should be achieved to sense the position of the control rod more precisely than that of the RSPT of the ABB-CE. This paper adopts seismic resistance reed switches to the position indicator in order to reduce the damages or impacts during the handling of the position indicator and earthquake

    H. Orpana

    2016-01-01

    Full Text Available Introduction: The Mental Health Strategy for Canada identified a need to enhance the collection of data on mental health in Canada. While surveillance systems on mental illness have been established, a data gap for monitoring positive mental health and its determinants was identified. The goal of this project was to develop a Positive Mental Health Surveillance Indicator Framework, to provide a picture of the state of positive mental health and its determinants in Canada. Data from this surveillance framework will be used to inform programs and policies to improve the mental health of Canadians. Methods: A literature review and environmental scan were conducted to provide the theoretical base for the framework, and to identify potential positive mental health outcomes and risk and protective factors. The Public Health Agency of Canada’s definition of positive mental health was adopted as the conceptual basis for the outcomes of this framework. After identifying a comprehensive list of risk and protective factors, mental health experts, other governmental partners and non-governmental stakeholders were consulted to prioritize these indicators. Subsequently, these groups were consulted to identify the most promising measurement approaches for each indicator. Results: A conceptual framework for surveillance of positive mental health and its determinants has been developed to contain 5 outcome indicators and 25 determinant indicators organized within 4 domains at the individual, family, community and societal level. This indicator framework addresses a data gap identified in Canada’s strategy for mental health and will be used to inform programs and policies to improve the mental health status of Canadians throughout the life course.

    Control rod position indication system is an important system in a nuclear power plant to monitor and display control rod position in all regimes of reactor operation. A new approach to design a control rod position indication system for sensing absolute position of control rod in Light Water Power Reactor has been undertaken. The proposed system employs an inductive type, hybrid measurement strategy providing both analog position as well as digital zone indication with built-in temperature compensation. The new design approach meets single failure criterion through redundancy in design without sacrificing measurement resolution. It also provides diversity in measurement technique by indirect position sensing based on analysis of drive coil current signature. Prototype development and qualification at room temperature of the control rod position indication system (CRPIS) has been demonstrated. The article presents the design philosophy of control rod position indication system, the new measurement strategy for sensing absolute position of control rod, position estimation algorithm for both direct and indirect sensing and a brief account associated processing electronics.

    As an information carrier and communication medium, indicators provide useful decision-making assistance in setting process goals and effectively reaching the goals. The main focus of this article is to investigate indicators' role in influencing planning through Strategic Environmental Assessment (SEA) especially related to Chinese experiences. From the perspective of planning and decision-making theory, the influence on planning is studied as influence of planning structure and influence of planning actors. Such a conceptual framework is applied in order to demonstrate how the use of indicators can influence planning through a SEA process. The study holds two empirical levels. On a general level, based on an online survey, this article investigates SEA practitioners' experiences in using indicators. On a case level, two urban plans are selected to provide more detailed experiences. The case level investigation is based on a documentary study and individual interviews with SEA practitioners/planners. By exploring how indicators influence planning through the structure of and the actors within SEA, this study tries to provide an overview of indicators' role in SEA. The results indicate that indicators are perceived as a useful tool in the Chinese SEA system. By improving and simplifying the procedures of SEA, the indicators exert more structural influence on SEA and on plan making. On the other hand, indicators are also shown to have more influence through political actors than found among technical actors. Copyright © 2017. Published by Elsevier B.V.

    Positive behaviour support (PBS) emphasises multi-component interventions by natural intervention agents to help people overcome challenging behaviours. This paper investigates which components are most effective and which factors might mediate effectiveness. Sixty-one staff working with individuals with intellectual disability and challenging behaviours completed longitudinal competency-based training in PBS. Each staff participant conducted a functional assessment and developed and implemented a PBS plan for one prioritised individual. A total of 1,272 interventions were available for analysis. Measures of challenging behaviour were taken at baseline, after 6 months, and at an average of 26 months follow-up. There was a significant reduction in the frequency, management difficulty, and episodic severity of challenging behaviour over the duration of the study. Escape was identified by staff as the most common function, accounting for 77% of challenging behaviours. The most commonly implemented components of intervention were setting event changes and quality-of-life-based interventions. Only treatment acceptability was found to be related to decreases in behavioural frequency. No single intervention component was found to have a greater association with reductions in challenging behaviour.

    2004-01-01

    A control rod position indicator named as tri-code inductance control rod position indicator with multi-coding-bars, which possesses simple structure, reliable operation and high precision, is developed. The detector of the indicator is composed of K coils, a compensatory coil and K coding bars. Each coding bar consists of several sections of strong magnetic cores, several sections of weak magnetic cores and several sections of non-magnetic portions. As the control rod is withdrawn, the coding bars move in the center of the coils respectively, while the constant alternating current passes the coils and makes them to create inductance alternating voltage signals. The outputs of the coils are picked and processed, and the tri-codes indicating rod position can be gotten. Moreover, the coding principle of the detector and its related structure are introduced. The analysis shows that the indicator owns more advantage over the coils-coding rod position indicator, so it can meet the demands of the rod position indicating in nuclear heating reactor (NHR).

    The Spanish feminist movement had its origins in the early 1970; in 1975 the first offical feminist conference made the following demands on the public authorities; 1) to abolish all sections of the Criminal Code which restrict women's freedom to control of their own bodies through making illegal information on and the purchase of contraceptives, 2) to decriminalize abortion, 3) to create family planning centers and to legalize contraceptives and provide them through the social security system, and 4) to include sex information in study courses. The distribution and sale of contraceptives was not legalized until 1978 and induced abortion is still a criminal offense. Nevertheless, after the 1975 meetins, a Coordinating Organization was established for the family planning committees that were functioning in the different feminist organizations. The problem of where to obtain contraceptives was solved by a group of feminist women which opened the 1st family planning center in Spain in 19779 This center was managed directly by members of the group. This and similar efforts culminated in the origin of the Movement for Movement for Family Planning that demanded in 1978; 1) the provision of sex information confronting the dominant sexual ideology and which is made a ccompulsory subject from school age, for both sexes; 2) free access to contraception for everyone; 3) the legalization of abortion, 4) the development of extensive information campaign on the problems of conception and contraception; and 5) the creation of independent, self-managed, family planning centers. There is now a Coordinating Organization of Family Planning Centers that was established in 1982. The socialist government is determined to create a public network of family planning centers.

    The Control Element Drive Mechanism (CEDM) for the integral reactor is designed to raise and lower the control rod in steps of 2mm in order to satisfy the design features of the integral reactor which are the soluble boron free operation and the use of a nuclear heating for the reactor start-up. The actual position of the control rod could be achieved to sense the magnet connected to the control rod by the position indicator around the upper pressure housing of CEDM. It is sufficient that the actual position information of control rod at 20mm interval from the position indicator is used for the core safety analysis. As the magnet moves upward along the position indicator assembly from the bottom to the top in the upper pressure housing, the output voltage increases linearly step-wise at 0.2VDC increments. Between every step there are transient areas which occur by a contact closing of three reed switches which is the 2-3-2 contact closing sequence. In this paper the output voltage signal corresponding to the position of control rod was estimated on the 2-1-2 contact closing sequence due to the aging of the magnet.

    Specifications are given for a position indicating system for determining the position of a movable member inside a sealed container such as the position of a control rod in a nuclear reactor. The system comprises a magnetic flux producing member mounted to the movable member so as to move with it, a series of magnetic reed contact units mounted along the outside of the sealed container to be individually actuated by the flux producer as the movable member moves within the sealed container to indicate the position of this member. Each of the reed contact units is connected to a source of alternating electric current to produce a magnetic flux field to minimize the flux differential between the actuated and unactuated reed contact positions. A second aspect of the invention provides for a low operating flux differential reed contact unit assembly for a position indicating system such that it is actuated by the magnetic member at one magnetic flux level and deactivated at a second level. There is a source of alternating current connected to a coil surrounding the reed contact unit so as to produce an alternating magnetic flux with amplitude less than the difference between the two levels. Variations are given, also diagrams and benefits. (U.K.)

    2007-01-01

    It has been hypothesized that Helicobacter pylori (Hp) infection may contribute to reduced stature, risk of hypertension or obesity. The aim was to evaluate body indices in Hp positive and negative persons. A total of 2436 subjects (4-100 years old) were tested for Hp status by 13 C-urea breath test. Data on height and weight were collected for 84%, and blood pressure for 80% of the study subjects. The prevalence of Hp infection was 41.6%. The odds ratio for a 10-year increase in age was 1.21 (95% CI 1.17-1.25, p-value <0.001). Statistically significant negative association of Hp positivity with body height was most pronounced in the younger age groups, while a positive association of Hp positivity with body mass index was only seen in those aged 15+ years. There was a negative effect of Hp positivity on systolic and diastolic blood pressure in subjects below 25 and a relatively strong positive effect on blood pressure in subjects over 65 years. Residual confounding by social characteristics as a possible explanation for the associations of Hp positivity with height and blood pressure cannot be excluded. Unmeasured factors related to social and family environment may cause the apparent association between Hp positivity and children's growth and blood pressure

    To evaluate patients who had undergone pyeloplasty for pelviureteric junction obstruction, by measuring the anteroposterior diameter (APD) of the renal pelvis in supine and prone positions, and determine whether a decrease in APD in prone position can exclude obstruction in dilated renal system. From January 2012 to December 2013, patients who had undergone pyeloplasty were evaluated by ultrasound in two centers. The difference of APD of the renal pelvis in supine and prone positions was obtained. Correlation was made with the pre- and post-pyeloplasty renal function by radionuclide renogram. There were 42 patients (31 males, 11 females; age range 5 months to 18 years). Residual hydronephrosis was detected in 41 patients of whom 35 patients (85%) showed decrease in APD by >10% in prone position. These patients and the one without hydronephrosis showed either no deterioration or improvement in renal function. Six patients (15%) showed either no change or increase in APD in prone position. Three patients (7.5%) were confirmed to have decrease in renal function indicating obstruction. Three patients (7.5%) showed no deterioration of renal function, but sluggish drainage on radionuclide renogram. Demonstration of decreased APD of renal pelvis in prone position by ultrasound is useful to differentiate obstructed from non-obstructed dilated renal system, and it correctly identified 85% candidates with successful pyeloplasty. In patients with no decrease or increase in APD at prone position, further follow-up is recommended to rule out obstruction

    The aim of this study was to evaluate whether normal controls and human immunodeficiency virus (HIV) patients with and without planning deficits differ on white matter integrity. A total of 34 HIV-positive patients with planning deficits were compared with 13 HIV-positive patients without planning deficits and 19 gender-, age-, and education-matched control subjects. Diffusion tensor imaging (DTI) was performed along 30 noncolinear directions in a 1.5-T scanner. For tract-based spatial statistics analysis, a white matter skeleton was created, and a permutation-based inference with 5000 permutations with a threshold of p < 0.05 was used to identify abnormalities in fractional anisotropy (FA). The median, radial, and axial diffusivities were also projected onto the mean FA skeleton. Compared with controls, HIV-positive patients with planning deficits had decreased FA in bilateral anterior thalamic radiations, bilateral inferior fronto-occiptal fasciculi, genu and splenium of the corpus callosum, bilateral superior longitudinal fascicule, and bilateral uncinate fasciculi. Compared to HIV-positive patients without planning deficits, patients with planning deficits had decreased FA in bilateral anterior thalamic radiations, bilateral inferior fronto-occiptal fasciculi, genu of the corpus callosum, bilateral superior longitudinal fascicule, and right uncinate fascicule. DTI can detect extensive white matter abnormalities in the normal-appearing white matter of HIV-positive patients with planning deficits compared with controls and HIV-positive patients without planning deficits.

  16. Bridging centrality: A new indicator to measure the positioning of actors in R&D networks

    Energy Technology Data Exchange (ETDEWEB)

    Scherngell, T.; Wanzenboeck, I.; Berge, L.

    2016-07-01

    In the recent past, we can observe growing interest in the STI community in the notion of positioning indicators, shifting emphasis to actors in the innovation process and their R&D inter-linkages with other actors. In relation to this, we suggest a new approach for assessing the positioning of actors relying on the notion of bridging centrality (BC). Based on the concept of bridging paths, i.e. a set of two links connecting three actors across three different aggregate nodes (e.g. organisations, regions or countries), we argue that triangulation in networks is a key issue for knowledge recombinations and the extension of an actor's knowledge base. As bridges are most often not empirically observable at the individual level of research teams, we propose an approximated BC measure that provides a flexible framework for dealing with the aggregation problem in positioning actors. Hereby, BC is viewed as a function of an aggregate node's (i) participation intensity in the network, (ii) its openness to other nodes (i.e. the relative outward orientation of network links), and iii) the diversification of links to other nodes. In doing so, we provide an integrative perspective that enables us to achieve a better understanding of the positioning of certain actors in R&D networks. An illustrative example on the co-patent network of European regions demonstrates the performance and usefulness of our BC measure for networks constructed at the aggregated level, i.e. regions in our example. A region's outward orientation and the diversification of its network links moderates the influence of regional scale on network centrality. This is a major strength of the measure, and it paves the way for future studies to examine the role of certain aggregate node's, and, by this, contributes to the debate on positioning indicators in the STI context.

    La Rosa, Daniele; Privitera, Riccardo; Martinico, Francesco; La Greca, Paolo

    2013-09-01

    Maintaining existing levels of landscape diversity is becoming more and more important for planning considering the increasing pressures on agricultural ecosystems due to soil sealing, sprawl processes and intensive agriculture. Norms for land-use regulation and measures for landscape Safeguard and Rehabilitation have to take into consideration these threats in landscape planning. Evaluating the diversity of agricultural ecosystems is a fundamental step for proposing sound approaches to planning and managing both soil and landscape, as well as maintaining the related ecosystem services. The paper proposes a method aimed at the qualitative evaluation of spatial diversity of agricultural landscapes using a reduced set of ecological indicators based on land-use vector data. Indicators are calculated for defined landscape units characterized by landscape homogeneity. GIS geoprocessing and spatial analysis functions are employed. The study area is the Province of Enna in Sicily (Italy), which is characterized by cultivation mosaics in its southern region, cereal cultivation in the central region and prevailing natural environments in the northern region. Results from the indicator calculations are used to define measures to be included in a Landscape Protection Plan. Safeguard and Rehabilitation measures are introduced, which link indicator scores to planning protection aims. The results highlight the relevance of some agricultural mosaics in proximity to streams and seasonal fluvial environments, where some undamaged natural environments are still present. For these areas, specific landscape safeguard measures are proposed to preserve their diversity features together with their original agricultural functions. The work shows that even with a reduced number of indicators, a differentiated set of measures can be proposed for a Landscape Protection Plan. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Monitoring of water services informs policy and planning for national governments and the international community. Currently, the international monitoring system measures the type of drinking water source that households use. There have been calls for improved monitoring systems over several decades, some advocating use of multiple indicators. We review the literature on water service indicators and frameworks with a view to informing debate on their relevance to national and international monitoring. We describe the evidence concerning the relevance of each identified indicator to public health, economic development and human rights. We analyze the benefits and challenges of using these indicators separately and combined in an index as tools for planning, monitoring, and evaluating water services. We find substantial evidence on the importance of each commonly recommended indicator--service type, safety, quantity, accessibility, reliability or continuity of service, equity, and affordability. Several frameworks have been proposed that give structure to the relationships among individual indicators and some combine multiple indicator scores into a single index but few have been rigorously tested. More research is needed to understand if employing a composite metric of indicators is advantageous and how each indicator might be scored and scaled.

  2. Home continuous positive airway pressure for cardiopulmonary indications in infants and children.

    A number of reports exist regarding the use of continuous positive airway pressure (CPAP) to manage obstructive sleep apnoea (OSA) in children, which we term 'conventional CPAP'. In contrast, there are few reports of home CPAP use for other indications, which we have grouped under the term 'cardiopulmonary'. The aims of this study were to (1) document cardiopulmonary indications for CPAP use in a cohort of infants and children, and (2) evaluate its effectiveness in this group. Hospital records were reviewed for 645 patients who were commenced on long-term CPAP over a 10-year period at a single-tertiary hospital (Children's Hospital at Westmead). This study evaluated the group where the primary indication for CPAP was not OSA ('cardiopulmonary CPAP'). Data evaluated included: demographics, diagnoses, indications for CPAP, hours of use (compliance) and sleep study results at baseline and on CPAP. Of 645 children, 148 (23%) used home CPAP for cardiopulmonary indications; and 130 (87.8%) of these were included. For this group, mean age at CPAP initiation was 18.6 ± 33.6 months (range one week to 16.8 years). Cardiopulmonary indications for CPAP use included: primary airway diseases 65 (50%), chronic lung diseases 33 (25.4%), congenital heart disease (CHD) 20 (15.4%), and both CHD and airway malacia 12 (9.2%). All sleep study variables improved on CPAP relative to the diagnostic sleep study (p 4 h/night). Interstitial lung diseases and other cardiorespiratory disorders, often of congenital origin, can be effectively treated with home CPAP whether they are associated with OSA or not. Sleep studies demonstrated improved gas exchange, sleep and reduced work of breathing with CPAP use. Copyright © 2018 Elsevier B.V. All rights reserved.

    The purpose of the study was to quantify the patellar J sign using traditional computed tomography (CT) scans. Fifty-three patients (fifty-three knees) who suffered from recurrent patellar instability were included and analyzed. The patellar J sign was evaluated pre-operatively during active knee flexion and extension. It was defined as positive when there was obvious lateral patellar translation, and negative when there was not. The CT scans were performed in all patients with full knee extension; and the parameters including bisect offset index (BOI), patellar-trochlear-groove (PTG) distance, and patellar lateral tilt angle (PLTA) were measured on the axial slices. All the three parameters were compared between the J sign-positive group (study group) and the J sign-negative group (control group). In addition, the optimal thresholds of the three CT scan parameters for predicting the positive patellar J sign were determined with receiver operating characteristic (ROC) curves, and the diagnostic values were assessed by the area under the curve (AUC). Among the fifty-three patients (fifty-three knees), thirty-seven (70%) showed obvious lateral patellar translation, which were defined as positive J sign (study group), and the remaining sixteen (30%) who showed no lateral translation were defined as negative J sign (control group). The mean values of the three CT parameters in the study group were all significantly larger compared to the control group, including BOI (121 ± 28% vs 88 ± 12%, P = 0.038), PTG distance (5.2 ± 6.6 mm vs - 4.4 ± 5.2 mm, P J sign was 97.5% (Sensitivity = 83.3%, Specificity = 87.5%). In this study, the prevalence of positive patellar J sign was 70%. The BOI measured from the axial CT scans of the knee joint can be used as an appropriate predictor to differentiate the positive J sign from the negative J sign, highlighting that the excessive lateral patellar translation on axial CT scan indicates positive

    Full Text Available This study aimed at learning about the nutritional profile of HIV-positive individuals undergoing antiretroviral therapy and at comparing the performance of nutritional-state indicators. A transversal study was performed on 94 patients attending the Tropical Diseases Outpatient Hospital of Botucatu Medical School (FMB - UNESP. The body mass index (BMI and the classification by Papini-Berto (PB were used to evaluate nutritional state, aiming at detecting malnutrition and obesity. The waist-to-hips ratio (W/HR and waist circumference (WC were adopted for identification of abdominal obesity and lipodystrophy. According to BMI, most of the individuals were eutrophic, followed by 30.9% overweight and 6.4% malnourished. By using the PB classification, the frequency of malnourished increased (22.3%. The analysis of the PB classification in relation to BMI indicated that the former presented high sensitivity and good specificity for malnutrition diagnosis, namely 100% and 83%, respectively. The prevalence of abdominal obesity was 7.44% according to WC, and a higher prevalence (38.3% was observed when taking W/HR into account. There was significant positive association between nutritional diagnosis according to PB and T CD4+ lymphocyte. The results support the use of PB classification for malnutrition detection as well as that of BMI and W/HR for overweight and fat redistribution.

    2003-04-01

    To examine the association between socio-economic position (SEP) and diet, by assessing the unadjusted and simultaneously adjusted (independent) contributions of education, occupation and household income to food purchasing behaviour. The sample was randomly selected using a stratified two-stage cluster design, and the response rate was 66.4%. Data were collected by face-to-face interview. Food purchasing was examined on the basis of three composite indices that reflected a household's choice of grocery items (including meat and chicken), fruit and vegetables. Brisbane City, Australia, 2000. : Non-institutionalised residents of private dwellings located in 50 small areas (Census Collectors Districts). When shopping, respondents in lower socio-economic groups were less likely to purchase grocery foods that were high in fibre and low in fat, salt and sugar. Disadvantaged groups purchased fewer types of fresh fruits and vegetables, and less often, than their counterparts from more advantaged backgrounds. When the relationship between SEP and food purchasing was examined using each indicator separately, education and household income made an unadjusted contribution to purchasing behaviour for all three food indices; however, occupation was significantly related only with the purchase of grocery foods. When education and occupation were simultaneously adjusted for each other, the socio-economic patterning with food purchase remained largely unchanged, although the strength of the associations was attenuated. When household income was introduced into the analysis, the association between education, occupation and food purchasing behaviour was diminished or became non-significant; income, however, showed a strong, graded association with food choice. The food purchasing behaviours of socio-economically disadvantaged groups were least in accord with dietary guideline recommendations, and hence are more consistent with greater risk for the development of diet

    The benefits of retrospective continuous glucose monitoring (retroCGM) recording have been widely explored in clinical studies, and many diabetes physicians routinely use this examination. However, the method of interpretation of CGM recordings has never been precisely described. An expert French panel of physicians met for two days to discuss several aspects of retroCGM use and to produce a position statement. The guidelines cover the indications for retroCGM, the general organization and practical implementation of CGM recordings, a description of the different devices available and guidelines for the interpretation of retroCGM recordings. This consensus document should help clinicians in the proper use of retroCGM. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  9. Typology and indicators of ecosystem services for marine spatial planning and management.

    2013-11-30

    The ecosystem services concept provides both an analytical and communicative tool to identify and quantify the link between human welfare and the environment, and thus to evaluate the ramifications of management interventions. Marine spatial planning (MSP) and Ecosystem-based Management (EBM) are a form of management intervention that has become increasingly popular and important globally. The ecosystem service concept is rarely applied in marine planning and management to date which we argue is due to the lack of a well-structured, systematic classification and assessment of marine ecosystem services. In this paper we not only develop such a typology but also provide guidance to select appropriate indicators for all relevant ecosystem services. We apply this marine-specific ecosystem service typology to MSP and EBM. We thus provide not only a novel theoretical construct but also show how the ecosystem services concept can be used in marine planning and management. Copyright © 2013 Elsevier Ltd.

  10. Play and optimal welfare: Does play indicate the presence of positive affective states?

    Science.gov (United States)

    Ahloy-Dallaire, Jamie; Espinosa, Julia; Mason, Georgia

    2017-11-16

    Play is commonly used to assess affective states in both humans and non-human animals. Play appears to be most common when animals are well-fed and not under any direct threats to fitness. Could play and playfulness therefore indicate pre-existing positive emotions, and thence optimal animal welfare? We examine this question by surveying the internal and external conditions that promote or suppress play in a variety of species, starting with humans. We find that negative affective states and poor welfare usually do suppress play (although there are notable exceptions where the opposite occurs). Furthermore, research in children suggests that beyond the frequency or total duration of play, poor welfare may additionally be reflected in qualitative aspects of this heterogeneous behaviour (e.g. display of solitary over social play; and the 'fragmentation' of play bouts) that are often overlooked in animals. There are surprisingly few studies of play in subjects with pre-existing optimal welfare or in unambiguously highly positive affective states, making it currently impossible to determine whether play can distinguish optimal or good welfare from merely neutral welfare. This therefore represents an important and exciting area for future research. Copyright © 2017 Elsevier B.V. All rights reserved.

    1975-01-01

    In scintigraphic diagnoses with positive indicators, the capacity of these indicators to fix themselves or to selectively concentrate in the neoplastic tissue is utilized. This selectivity could be due to several biochemical peculiarities of the tumor cells in relation to surrounding cells: the presence on the membrane of particular chemical groups which allow these cells to invade adjacent tissue without being subject to contact inhibition; the presence on these same membranes of antigenic determinants which are particular to these cells and which can be revealed with specific antibodies; a high concentration of nucleic acid in tumor cells, with the associated possibility of fixing substances having a particular tropism for nucleic acids or for their chemical constituents; an elevated rate of nucleic acid synthesis, with an associated increase in the incorporation of precursors and also of substances which specifically interfere with this biochemical pathway; in numerous cases, tumor cells produce high quantities of acidic metabolites which must be neutralized by equivalent quantities of anions, the latter entering the cells by active transport phenomena; in tumors which develop particularly rapidly, there is a development of degenerative processes with an accumulation of degradation products; in metastatic tumors, the cells have metabolic and biosynthetic activities which are a function of the original tissue, with the possiblity of a clear metabolic difference in relation to adjacent tissues [fr

    2016-04-01

    Despite the well-developed trophic classification of soil nematodes, their position in soil food webs is still little understood. Observed deviations from the typical feeding strategy indicate that a simplified trophic classification probably does not fully reflect actual trophic interactions. Furthermore, the extent and functional significance of nematodes as prey for other soil animals remains unknown. Stable isotope analysis (SIA) is powerful tool for investigating the structure of soil food webs, but its application to the study of soil nematodes has been limited to only a few studies. We used stable isotope analysis to gain a better understanding of trophic links of several groups of soil nematodes in two boreal forests on albeluvisol. We investigated four taxonomic groups of nematodes: Mononchida, Dorylaimida, Plectidae and Tylenchidae (mostly from the genus Filenchus), that according to the conventional trophic classification represent predators, omnivores, bacterivores and root-fungal feeders, respectively. To assess the trophic position of nematodes, we used a comparison against a set of reference species including herbivorous, saprophagous and predatory macro-invertebrates, oribatid and mesostigmatid mites, and collembolans. Our results suggest that trophic position of the investigated groups of soil nematodes generally corresponds to the conventional classification. All nematodes were enriched in 13C relative to Picea abies roots and litter, and mycorrhizal fungal mycelium. Root-fungal feeders Tylenchidae had δ15N values similar to those of earthworms, enchytraeids and Entomobrya collembolans, but slightly lower δ13C values. Bacterivorous Plectidae were either equal or enriched in 15N compared with saprophagous macroinvertebrates and most mesofauna species. Omnivorous Dorylaimida and predatory Mononchida were further enriched in 15N and their isotopic signature was similar to that of predatory arthropods. These data confirm a clear separation of

    We assessed the reliability of implant placement after virtual planning of implant positions using cone-beam CT data and surgical guide templates. A total of 102 patients (250 implants, 55.4% mandibular; mean patient age, 40.4 years) who had undergone implant treatment therapy in an armed forces dental clinic (Cologne, Germany) between July 1, 2005 and December 1, 2005. They were treated with a system that allows transfer of virtual planning to surgical guide templates. Only in eight cases the surgical guides were not used because a delayed implant placement was necessary. In four posterior mandibular cases, handling was limited because of reduced interocclusal distance, requiring 50% shortening of the drill guides. The predictability of implant size was high: only one implant was changed to a smaller diameter (because of insufficient bone). In all cases, critical anatomical structures were protected and no complications were detected in postoperative panoramic radiographs. In 58.1% (147) of the 250 implants, a flapless surgery plan was realized. Implant placement after virtual planning of implant positions using cone beam CT data and surgical templates can be reliable for preoperative assessment of implant size, position, and anatomical complications. It is also indicative of cases amenable to flapless surgery.

  16. Positive selection in octopus haemocyanin indicates functional links to temperature adaptation.

    Octopods have successfully colonised the world's oceans from the tropics to the poles. Yet, successful persistence in these habitats has required adaptations of their advanced physiological apparatus to compensate impaired oxygen supply. Their oxygen transporter haemocyanin plays a major role in cold tolerance and accordingly has undergone functional modifications to sustain oxygen release at sub-zero temperatures. However, it remains unknown how molecular properties evolved to explain the observed functional adaptations. We thus aimed to assess whether natural selection affected molecular and structural properties of haemocyanin that explains temperature adaptation in octopods. Analysis of 239 partial sequences of the haemocyanin functional units (FU) f and g of 28 octopod species of polar, temperate, subtropical and tropical origin revealed natural selection was acting primarily on charge properties of surface residues. Polar octopods contained haemocyanins with higher net surface charge due to decreased glutamic acid content and higher numbers of basic amino acids. Within the analysed partial sequences, positive selection was present at site 2545, positioned between the active copper binding centre and the FU g surface. At this site, methionine was the dominant amino acid in polar octopods and leucine was dominant in tropical octopods. Sites directly involved in oxygen binding or quaternary interactions were highly conserved within the analysed sequence. This study has provided the first insight into molecular and structural mechanisms that have enabled octopods to sustain oxygen supply from polar to tropical conditions. Our findings imply modulation of oxygen binding via charge-charge interaction at the protein surface, which stabilize quaternary interactions among functional units to reduce detrimental effects of high pH on venous oxygen release. Of the observed partial haemocyanin sequence, residue 2545 formed a close link between the FU g surface and the

    The position of lung scintigraphy in diagnostic strategy is discussed. This technique appears to afford the key examination in severe pulmonary embolism because of its qualities, which are: - speed of execution, - absolute harmlessness, - diagnostic safety. Taking these points in order: - speed of execution is ensured by the very rapid uptake of I 131-labelled albumin macroaggregates (usable immediately) and the existence of the gamma camera; - harmlessness of the examination by the use of non-allergenic radioactive tracers and doses not significantly restricting the vascular bed still perfused; whichever of the two possible techniques is employed (scanner and gamma camera) the examination can always be practised without getting the patient out of bed, which avoids the risk of clot migration due to movement; - certainty of the result by the fact that in the event of a surgical indication the circulation cut-off image is spectacular and obvious in fact a lung amputation image must be equal to or greater than 50% of the pulmonary field before an operation is decided upon all other images remaining within the scope of a hypocoagulant treatment. A study was carried out in a cardio-vascular surgery department on 28 patients hospitalised with a possible view to embolectomy. Lung scintigraphy allows a quick exploration of the minor circulation. In the special clinical situation of the patients, for whom the advisability of an embolectomy is discussed, the scintigraphic examination provides the key: if normal it eliminates the diagnosis absolutely; if not it reveals without extra risk the spectacular obliterations of the vascular bed on which any therapeutic decision, medical or surgical is based [fr

  19. Orthognathic positioning system: intraoperative system to transfer virtual surgical plan to operating field during orthognathic surgery.

    Polley, John W; Figueroa, Alvaro A

    2013-05-01

    To introduce the concept and use of an occlusal-based "orthognathic positioning system" (OPS) to be used during orthognathic surgery. The OPS consists of intraoperative occlusal-based devices that transfer virtual surgical planning to the operating field for repositioning of the osteotomized dentoskeletal segments. The system uses detachable guides connected to an occlusal splint. An initial drilling guide is used to establish stable references or landmarks. These are drilled on the bone that will not be repositioned adjacent to the osteotomy line. After mobilization of the skeletal segment, a final positioning guide, referenced to the drilled landmarks, is used to transfer the skeletal segment according to the virtual surgical planning. The OPS is digitally designed using 3-dimensional computer-aided design/computer-aided manufacturing technology and manufactured with stereolithographic techniques. Virtual surgical planning has improved the preoperative assessment and, in conjunction with the OPS, the execution of orthognathic surgery. The OPS has the possibility to eliminate the inaccuracies commonly associated with traditional orthognathic surgery planning and to simplify the execution by eliminating surgical steps such as intraoperative measuring, determining the condylar position, the use of bulky intermediate splints, and the use of intermaxillary wire fixation. The OPS attempts precise translation of the virtual plan to the operating field, bridging the gap between virtual and actual surgery.

    Full Text Available An app to evaluate the Street Cleanliness and Waste Collection Service was developed. This app is based on a Plan of Indicators that can be used to evaluate the Street Cleanliness and Waste Collection Service of Santander municipality. Specific methodologies for calculating and evaluating 59 indicators have been developed to obtain information regarding the status of the different elements of the service. The Plan of Indicators has been applied to Santander city. The app was designed to address, but is not limited to, the following goals: i to obtain, store and calculate information regarding the above indicators and ii to disseminate the results of the status of the elements of the Service to the public sector. The app that was developed can provide a quick view of the results obtained for each indicator in each district, which is useful for making an appropriate diagnosis of the city’s cleanliness and is the first step in the decision making and Service optimisation processes. Detailed results for the Street Cleanliness Index are shown for each district of Santander city. The Street Cleanliness Index values are also related to the Frequency Street Cleanliness Services parameters. Pearson correlation coefficient results suggest that an inverse relationship between the Street Cleanliness Index values and the Frequency Street Cleanliness Services/population density ratio exists (R2 = −0.63. The results show that Street Cleanliness Index worst values exist for those districts that have a lower Frequency Street Cleanliness Services /population density parameter. The results are useful for designing and optimising the Street Cleanliness Service. For the decision making process, resources should be allocated where necessary, which seems to be those districts with lower Frequency Street Cleanliness Services /population density ratios.

  4. Key Performance Indicators for the Impact of Cognitive Assembly Planning on Ramp-Up Process

    Directory of Open Access Journals (Sweden)

    Christian Buescher

    2012-01-01

    Full Text Available Within the ramp-up phase of highly automated assembly systems, the planning effort forms a large part of production costs. Due to shortening product lifecycles, changing customer demands, and therefore an increasing number of ramp-up processes, these costs even rise. So assembly systems should reduce these efforts and simultaneously be flexible for quick adaption to changes in products and their variants. A cognitive interaction system in the field of assembly planning systems is developed within the Cluster of Excellence “Integrative production technology for high-wage countries” at RWTH Aachen University which integrates several cognitive capabilities according to human cognition. This approach combines the advantages of automation with the flexibility of humans. In this paper the main principles of the system's core component—the cognitive control unit—are presented to underline its advantages with respect to traditional assembly systems. Based on this, the actual innovation of this paper is the development of key performance indicators. These refer to the ramp-up process as a main objective of such a system is to minimize the planning effort during ramp-up. The KPIs are also designed to show the impact on the main idea of the Cluster of Excellence in resolving the so-called Polylemma of Production.

    2011-12-15

    This paper proposes an indicators system to analyse the sustainability of tourist activity at rural destinations in countries with a consolidated tourism sector. The proposed system aims at providing tourist managers and policy-makers with information to better understand the transition to sustainability at specific destinations and to encourage them to carry out corresponding policy and management responses. To illustrate how indicators can be quantified, we create a practical guideline on how to use the statistical information available. Likewise, we suggest a method for obtaining sustainability indexes by aggregation that reduces the subjectivity associated with the composite indicator. This procedure is based on the combination of principal component analysis and distance to a reference point. Together with the definition of sustainable tourism indicators, we explain how to use these systems and sustainability indexes to fulfil three practical uses in tourism sector planning: the comparison and characterisation of destinations, the definition of benchmarking practices, and the quantification of sustainable tourism objectives. Each practical use is illustrated using the case of rural zones in a consolidated destination such as Andalusia. Copyright © 2011 Elsevier B.V. All rights reserved.

    2007-01-17

    Social position refers to a person's social rank. Many goods have positional value because they increase the status of their consumers. Positional goods include fashionable jewellery and clothing, luxurious homes and vehicles, and extravagant entertainment. Many motorists choose vehicles with greater potential speeds and off-road abilities than actually needed because these features are considered prestigious. This paper examined how positional value affects transportation decisions and investigated the resulting economic impacts. These included impacts on social welfare and external costs. The paper also discussed implications for transport policy and planning. The paper discussed the science of happiness and included an excerpt from a newspaper article on money and happiness. The paper also included an analysis of popular television shows and Internet blogs. Transportation impacts were also examined, with reference to motor vehicle ownership, luxury vehicles, mode choice, long-distance recreation travel, planning practices, and industrial development policy. A table was also presented that summarized the categories of prestige value travel impacts. The paper also presented possible offsetting benefits and implications for planning. 40 refs., 1 tab., 11 figs.

    A concept is proposed to simplify patient positioning and scan planning to improve ease of use and workflow in MR. After patient preparation in front of the scanner the operator selects the anatomy of interest by a single push-button action. Subsequently, the patient table is moved automatically into the scanner, while real-time 3D isotropic low-resolution continuously moving table scout scanning is performed using patient-independent MR system settings. With a real-time organ identification process running in parallel and steering the scanner, the target anatomy can be positioned fully automatically in the scanner's sensitive volume. The desired diagnostic examination of the anatomy of interest can be planned and continued immediately using the geometric information derived from the acquired 3D data. The concept was implemented and successfully tested in vivo in 12 healthy volunteers, focusing on the liver as the target anatomy. The positioning accuracy achieved was on the order of several millimeters, which turned out to be sufficient for initial planning purposes. Furthermore, the impact of nonoptimal system settings on the positioning performance, the signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) was investigated. The present work proved the basic concept of the proposed approach as an element of future scan automation. (c) 2009 Wiley-Liss, Inc.

    The application of lipiodol injections as markers around bladder tumors combined with the use of CBCT for image guidance enables daily on-line position correction based on the position of the bladder tumor. However, this might introduce the risk of underdosing the pelvic lymph nodes. In this study several correction strategies were compared. For this study set-up errors and tumor displacements for ten complete treatments were generated; both were based on the data of 10 bladder cancer patients. Besides, two IMRT plans were made for 20 patients, one for the elective field and a boost plan for the tumor. For each patient 10 complete treatments were simulated. For each treatment the dose was calculated without position correction (option 1), correction on bony anatomy (option 2), on tumor only (option 3) and separately on bone for the elective field (option 4). For each method we analyzed the D{sub 99%} for the tumor, bladder and lymph nodes and the V{sub 95%} for the small intestines, rectum, healthy part of the bladder and femoral heads. CTV coverage was significantly lower with options 1 and 2. With option 3 the tumor coverage was not significantly different from the treatment plan. The ΔD{sub 99%} (D{sub 99%,} {sub option} {sub n} - D{sub 99%,} {sub treatment} {sub plan}) for option 4 was small, but significant. For the lymph nodes the results from option 1 differed not significantly from the treatment plan. The median ΔD{sub 99%} of the other options were small, but significant. ΔD{sub 99%} for PTV{sub bladder} was small for options 1, 2 and 4, but decreased up to -8.5 Gy when option 3 was applied. Option 4 is the only method where the difference with the treatment plan never exceeds 2 Gy. The V{sub 95%} for the rectum, femoral heads and small intestines was small in the treatment plan and this remained so after applying the correction options, indicating that no additional hot spots occurred.

    The scope of environmental impact statements prepared during the past few years has steadily expanded to incorporate all aspects of the social as well as the natural environment, including demographic, economic, social, political, and cultural conditions. Broadly conceived, social impacts are alterations in people's living conditions that occur in conjunction with a new policy, program, or project, and that (1) are in addition to all other concurrent changes produced by other factors, and (2) are seen by those affected as significant social events. Since any social environment is constantly changing, the crucial problems in analyzing social impacts are to identify those social alterations that are a direct or indirect result of the specific action under examination, apart from all other events and changes, and to determine which of these alterations are having significant social effects on the people involved. Three features of this conception of social impacts are especially noteworthy. First, although impacts are often thought of as undesirable or detrimental in nature, they may also be desirable or beneficial. Second, although impacts are often described as caused by prior intervening innovations, in reality they always interact with their original causes in a reciprocal process, either immediately or after some time lag. Third, the purpose of social impact assessment is to enable policy makers to anticipate and plan for potential impacts before they occur, and then act to prevent or mitigate undesired impacts. A new methodology for performing social impact assessment and management studies that meet current needs by emphasizing standardized social indicators and social planning techniques is proposed. We refer to our approach as the Social Impact and Planning (SIP) method of social impact assessment

    In discussing issues of landscape change, the complex relationships in the landscape have to be assessed. In participative planning processes, 3D visualisations have a high potential as an aid in understanding and communicating characteristics of landscape conditions by integrating visual and non-visual landscape information. Unclear is, which design and how much interactivity is required for an indicator visualisation that would suit stakeholders best in workshop situations. This paper describes the preparation and application of three different types of integrated 3D visualisations in workshops conducted in the Entlebuch UNESCO Biosphere Reserve (CH). The results reveal that simple representations of a complex issue created by draping thematic maps on the 3D model can make problematic developments visible at a glance; that diagrams linked to the spatial context can help draw attention to problematic relationships not considered beforehand; and that the size of species as indicators of conditions of the landscape's production and biotope function seems to provide a common language for stakeholders with different perspectives. Overall, the of the indicators the functions required to assist in information processing. Further research should focus on testing the effectiveness of the integrated visualisation tools in participative processes for the general public.

  14. Innovation indices: the need for positioning them where they properly belong.

    Science.gov (United States)

    Kozłowski, Jan

    A specific quality of the discussion about innovation indices (scoreboards) is that more often than not the subject is dealt with from a purely technical point of view. Such a narrow approach silently assumes that indices used as a policy tool are an accurate reflection of the phenomenon and should not be questioned, and also that the whole discussion concerning them should refer to methodological aspects and is best left to the statisticians. This author is of the opinion that for an accurate evaluation of the value of indices as a policy tool, it is necessary to consider the matter from the broader point of view and from the context in which such indices are generated and used. This article puts forward the thesis that progress in science and innovation policy studies depends on a diversity of issues, approaches and perspectives. If that is the case, maintaining thematic and methodological variety may be more important than creating coherent and closed analytical tools, i.e. indices. The advantage of indices is that they focus attention on those variables which are deemed to be key. Among their disadvantages, however, are their highly abstract nature (in order to understand innovation-related phenomena, it is necessary to study them in tangible, composite forms); their tendency to skip unmeasurable determinants; their prior acceptance of definitions and concepts of innovation (instead of searching for them); the way they apply a single yardstick to diverse countries and regions, assumed linearity and causality in a complex and non-linear world, the way they direct policy towards implementing indicators (rather than identifying and solving problems). It is suggested that big data revolution will allow the emergence of a new measurement tools that will replace innovation indices.

    Reducing emissions of VOCs (volatil organic compounds) is a top-priority environmental goal, because when they react in the atmosphere with NO X , CO and solar radiation, they form tropospheric ozone, a pollutant that has a large environmental impact and contributes to world climate change. The most innovative part of the solvent directive concerns the Solvent Management Plan (SMP): a very useful tool, especially for small and medium-sized enterprises. With relatively small changes, the SMP can be turned into a Solvent Management System (SMS) having the features of an Environmental Management System. By applying an SMP-SMS, a great number of indicators can be developed, analysed and used to improve eco-efficiency; furthermore, the SMP-SMS can help local authorities in charge of environmental control procedures, in decision-making processes [it

    Women in Nepal have low status, especially younger women in co-resident households. Nepal also faces high levels of household food insecurity and malnutrition, and stagnation in uptake of modern family planning methods. This study aims to understand if household structure and food insecurity interact to influence family planning use in Nepal. Using data on married, non-pregnant women aged 15-49 with at least one child from the Nepal 2011 Demographic and Health Survey (N = 7,460), we explore the relationship between women's position in the household, food insecurity as a moderator, and family planning use, using multi-variable logistic regressions. We adjust for household and individual factors, including other status-related variables. In adjusted models, living in a food insecure household and co-residing with in-laws either with no other daughter-in-laws or as the eldest or youngest daughter-in-law (compared to not-co-residing with in-laws) are all associated with lower odds of family planning use. In the interaction model, younger-sisters-in-law and women co-residing with no sisters-in-law in food insecure households have the lowest odds of family planning use. This study shows that household position is associated with family planning use in Nepal, and that food insecurity modifies these associations-highlighting the importance of considering both factors in understanding reproductive health care use in Nepal. Policies and programs should focus on the multiple pathways through which food insecurity impacts women's reproductive health, including focusing on women with the lowest status in households.

    Family planning programmes in developing countries need a better understanding of nurse-patient communication in order to improve the quality of counselling. To identify factors in the clinic and in the community that enable nurses and patients to communicate effectively with one another. The study explored the personal experiences of nurses and patients who communicate especially effectively during family planning consultations (so-called "positive deviants"). Sixty-four randomly selected public clinics located in East Java, Indonesia. Seven positive deviant nurses and 32 positive deviant patients were identified from among 64 nurses and 768 patients who participated in an earlier patient coaching study. Flooding prevented 5 patients from participating in the study, reducing their number to 27. Investigators conducted: (1) a content analysis of qualitative data collected by structured in-depth interviews and focus-group discussions (FGDs) with positive deviant nurses and patients, and (2) analyses of variance (ANOVA) of quantitative data on clinic, nurse, and patient characteristics. Positive deviant nurses identified four factors, listed in rough order of importance, that helped them communicate effectively: independent study to strengthen their knowledge and skills; communication aids; feedback from colleagues; and motivation stemming from a desire to help people, patients' appreciation, husband's support, and increased income. Positive deviant patients identified five enabling factors: motivation due to their need for a service; confidence in their own communication skills; positive feedback from nurses; belief in patients' right and responsibility to communicate with nurses; and communication aids. Insights from positive deviant nurses and patients suggest that efforts to improve nurse-patient communication should go beyond conventional communication skills training. Managers should consider a mix of clinic-based interventions (such as peer feedback

    The dosimetric impact of random and systematic multi-leaf collimator (MLC) leaf position errors is relatively unknown for head and neck intensity-modulated radiotherapy (IMRT) patients. In this report we studied 17 head and neck IMRT patients, including 12 treated with simple plans ( 100 segments). Random errors (-2 to +2 mm) and systematic errors (±0.5 mm and ±1 mm) in MLC leaf positions were introduced into the clinical plans and the resultant dose distributions were analyzed based on defined endpoint doses. The dosimetric effect was insignificant for random MLC leaf position errors up to 2 mm for both simple and complex plans. However, for systematic MLC leaf position errors, we found significant dosimetric differences between the simple and complex IMRT plans. For 1 mm systematic error, the average changes in D 95% were 4% in simple plans versus 8% in complex plans. The average changes in D 0.1cc of the spinal cord and brain stem were 4% in simple plans versus 12% in complex plans. The average changes in parotid glands were 9% in simple plans versus 13% for the complex plans. Overall, simple IMRT plans are less sensitive to leaf position errors than complex IMRT plans

    Full Text Available Well-designed and implemented selection is one of the important prerequisites for achieving the expected results in the modern competitive sport at all levels. The aim of this work was to determine how the selection was made for Serbian League players, on the basis of their certain motor parameters and the positions in the team. A sample of 25 senior players of a football team competing in the Serbian League is divided into four sub-samples, based on team positions. For assessment of motor characteristics following tests were used: long jump (LJ, Abalac test (AT; 10 seconds push-ups (PU, 30 seconds trunk bends (TB, 20 meter flying start running (20FSR, 20 meter high start running (20HSR, 50 meter high start running (50HSR and Cooper test (CT . Based on the obtained results it can be concluded that there are significant differences for variable 20FSR and variable CT (F = 3754, 9835, p = .027, .000, respectively. Three canonical discriminant functions were singled out, where the first explained even 84.6%, the second 14.5% and the third only 1% of the total variance, or in summary first two functions explained 99.0% of the variance. It can be concluded that the selected players, in terms of the position in the team, distinguished first by performing on the Cooper test, followed by the result of 20 meter flying start running, 20 meter high start running, 50 meter high start running, trunk bends, and finally by Abalac test, push-ups and long jump. Observed as a function of certain motor characteristics, it could be concluded that in the selection of players in terms of the playing position confidence level was 72.0% in general level, with the most reliable for goalkeepers (100%, midfielders (71.4% and defensive players (70.0%, while the smallest was at strikers (50%.

    It is necessary to use health indicators describing the conditions of all individuals in a population, not just of those who have a disease or die. To introduce a method to collect population indicators of psychomotor development in children younger than 6 years old and show its results. Data were obtained from a cross-sectional assessment regarding compliance with 13 developmental milestones (selected from the national reference) conducted in 5465 children using five surveys administered by the Matanza-Riachuelo River Basin Authority in areas of this basin where a high proportion of families with unmet basic needs live. For each survey, a logistic regression analysis was used to estimate the median age at attainment of the 13 developmental milestones. A linear regression model between the estimated age at attainment of the 13 milestones was adjusted for each survey based on the corresponding age at attainment of the national reference. Based on this model, three indicators were defined: overall developmental quotient, developmental quotient at 4 years old, and developmental trend. Results from the five surveys ranged between 0.74 and 0.85, 0.88 and 0.81, and -0.15 and -0.26 for the overall developmental quotient, developmental quotient at 4 years old, and developmental trend, respectively. A distinct developmental delay and an increasing trend in delay with age were observed. Indicators are easily interpreted and related to social indicators (unmet basic needs, etc.). Collecting the information necessary to make estimations takes little time and can be applied to population groups, but not on an individual level. Sociedad Argentina de Pediatría.

    Effectively communicating the uncertainty that is inherent in any kind of geographic information remains a challenge. This paper investigates the efficacy of animation as a visual variable to represent positional uncertainty in a web mapping context. More specifically, two different kinds...... of animation (a ‘bouncing’ and a ‘rubberband’ effect) have been compared to two static visual variables (symbol size and transparency), as well as different combinations of those variables in an online experiment with 163 participants. The participants’ task was to identify the most and least uncertain point...... visualizations using symbol size and transparency. Somewhat contradictory to those results, the participants showed a clear preference for those static visualizations....

    The conformity index (CI) is an indicator to assess the degree of congruence between a shape of reference isodose volume (VRI) and a shape of the target volume (TV). Two concepts are included in the CI, which are the target coverage and the degree of normal tissue sparing in the proximity of the target. Even though this could be verified by a manual review of dose distributions calculated on patient CT images slice by slice, detailed comparisons among several treatment plans would be inconvenient. The conformity could be also verified by reviewing dose-volume histograms (DVHs) of each structure calculated by treatment planning system (TPS). The prerequisite for this is the contouring of not only organs at risk (OARs) but also every structure in a patient body, which is not practical in the clinic. Therefore, a value possible to quantify the conformity was needed, and various studies on CI have been performed. Various CIs have been developed since 1993. Most of them are based on the calculation of the volumes except for the CI suggested by Wu et al. and Cheung et al. which were based on the distance. The aim of this study was to develop new CIs based on the calculations of angles and distances. The CI angle based on the analysis of the angle differences as well as the CIabs{sub d}istance and the CIdistance based on the analysis of the distances between the TV and the VRI were developed and evaluated in this study. The CI distance with Sornatomedins better performances than the CIangle and the CIabs{sub d}istance as well as the conventional CIs in various situations.

    Beach nourishment, a method for mitigating coastal storm damage or chronic erosion by deliberately replacing sand on an eroded beach, has been the leading form of coastal protection in the United States for four decades. However, investment in hazard protection can have the unintended consequence of encouraging development in places especially vulnerable to damage. In a comprehensive, parcel-scale analysis of all shorefront single-family homes in the state of Florida, we find that houses in nourishing zones are significantly larger and more numerous than in non-nourishing zones. The predominance of larger homes in nourishing zones suggests a positive feedback between nourishment and development that is compounding coastal risk in zones already characterized by high vulnerability.

    Obesity and micronutrient deficiencies contribute to the risk of cardiometabolic diseases such are type 2 diabetes mellitus and cardiovascular disease (CVD). We examined the frequency of concomitant deficit of magnesium (Mg) and vitamin D in obese patients and evaluated the connection of these combined deficiencies with indicators of cardiometabolic risk in non-diabetic subjects. Non-diabetic middle aged adults (n = 80; mean age 36 ± 4 years, 52% women) were recruited based on weight/adiposity parameters [i.e. body mass index (BMI) and body fat percentage (FAT%)]. Cardiometabolic risk indicators [insulin resistance (Homeostatic Model Assessment for insulin resistance (HOMA-IR)) and CVD risk (Framingham risk score for predicting 10-year CVD)], Mg status [i.e. total serum Mg concentration (TMg), chronic latent Mg deficiency (CLMD) - 0.75-0.85 mmol/L], vitamin D status [i.e. serum concentration of 25-hydroxyvitamin D (25(OH)D), vitamin D deficiency <50 nmol/l] were assessed. Among obese subjects 36% presented a combination of vitamin D deficiency and CLMD. In all studied patients, 25(OH)D and TMg levels both, individually and combined, showed a negative linear correlation with HOMA-IR and CVD risk. In subjects with CLMD (TMg ˂0.85 mmol/L), a negative linear coefficient was found between 25(OH)D and, HOMA-IR and CVD risk, compared with subjects with normal TMg status (TMg ≥0.85 mmol/L). CLMD and vitamin D deficiency may commonly be present in obese non-diabetic subjects. Individually and combined, both deficiencies predispose non-diabetic patients to increased risk of cardiometabolic diseases. Maintaining normal Mg status may improve the beneficial effects of vitamin D on cardiometabolic risk indicators.

    Evaluation of quality of care is an integral part of modern healthcare, and has become an indispensable tool for health authorities, the public, the press and patients. However, measuring quality of care is difficult, because it is a multifactorial and multidimensional concept that cannot be estimated solely on the basis of patients' clinical outcomes. Thus, measuring the process of care through quality indicators (QIs) has become a widely used practice in this context. Other professional societies have published QIs for the evaluation of quality of care in the context of acute myocardial infarction (AMI), but no such indicators exist in Europe. In this context, the European Society of Cardiology (ESC) Acute Cardiovascular Care Association (ACCA) has reflected on the measurement of quality of care in the context of AMI (ST segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI)) and created a set of QIs, with a view to developing programmes to improve quality of care for the management of AMI across Europe. We present here the list of QIs defined by the ACCA, with explanations of the methodology used, scientific justification and reasons for the choice for each measure.

  7. Anticipatory planning and control of grasp positions and forces for dexterous two-digit manipulation.

    Dexterous object manipulation requires anticipatory control of digit positions and forces. Despite extensive studies on sensorimotor learning of digit forces, how humans learn to coordinate digit positions and forces has never been addressed. Furthermore, the functional role of anticipatory modulation of digit placement to object properties remains to be investigated. We addressed these questions by asking human subjects (12 females, 12 males) to grasp and lift an inverted T-shaped object using precision grip at constrained or self-chosen locations. The task requirement was to minimize object roll during lift. When digit position was not constrained, subjects could have implemented many equally valid digit position-force coordination patterns. However, choice of digit placement might also have resulted in large trial-to-trial variability of digit position, hence challenging the extent to which the CNS could have relied on sensorimotor memories for anticipatory control of digit forces. We hypothesized that subjects would modulate digit placement for optimal force distribution and digit forces as a function of variable digit positions. All subjects learned to minimize object roll within the first three trials, and the unconstrained device was associated with significantly smaller grip forces but larger variability of digit positions. Importantly, however, digit load force modulation compensated for position variability, thus ensuring consistent object roll minimization on each trial. This indicates that subjects learned object manipulation by integrating sensorimotor memories with sensory feedback about digit positions. These results are discussed in the context of motor equivalence and sensorimotor integration of grasp kinematics and kinetics.

    Purpose: Resection margin status is one of the most significant factors for local recurrence in patients with ductal carcinoma in situ (DCIS) treated with breast-conserving surgery with or without radiation. However, its impact on chest wall recurrence in patients treated with mastectomy is unknown. The purpose of this study was to determine chest wall recurrence rates in women with DCIS and close ( 5 cm or diffuse disease. Median width of the close final margin was 2 mm. Nineteen patients had margins of <1 mm. One of these 59 patients experienced a chest wall recurrence with regional adenopathy, followed by distant metastases 2 years following skin-sparing mastectomy. The DCIS was high-grade, 4 cm, with a 5-mm deep margin. A second patient developed an invasive cancer in the chest wall 20 years after her mastectomy for DCIS. This cancer was considered a new primary site arising in residual breast tissue. Conclusions: The risk of chest wall recurrence in this series of patients is 1.7% for all patients and 3.3% for high-grade DCIS. One out of 20 (5%) patients undergoing skin sparing or total skin-sparing mastectomy experienced a chest wall recurrence. This risk of a chest wall recurrence appears sufficiently low not to warrant a recommendation for postmastectomy radiation therapy for patients with margins of <5 mm. There were too few patients with positive margins to draw any firm conclusions.

    2003-01-01

    Full Text Available In the actual Swiss cantonal planning practice every 10 years in general, there is a review of the guiding plan. The plan’s evaluation typically takes place shortly before the revision process. In the interstitial time, the guiding plan’s effectiveness can only be anticipated. In the review, a survey of both, the desired and unwanted spatial effects are often absent. As a result, a thorough analysis of the effects and the direction of the spatial development cannot be accomplished. A spatial plan that is geared to the principle of sustainability needs the outputs of such an analysis. Development assessments are required to verify the plans’ effects, well-defined goals to assist in rectifying deviations, key indicators to identify efficiency potentials, and precautionary measures to allow for an adaptable and responsive planning methodology. The instruments, which might assist in the cantonal guiding plan objectives implementation, do exist. Such instruments are monitoring, controlling and benchmarking (with the support of indicators. These tools can assist in ensuring the plan’s overall value and the effectiveness and appropriateness of the ensuing development. By using these tools and a sound planning methodology, unsustainable spatial development can be tracked early and rectified with appropriated measures. The control as this system’s central instrument is presented here and its application opportunities in the cantonal guiding planning are discussed. In order to achieve a sustainable spatial development and a more dynamic guiding planning, the application of control and benchmarking is crucial.

    Full text: At our institution there has developed a practice of referring some patients for assessment of pulmonary embolism (PE) because of a positive L-dimer test but without standard clinical indications. Therefore this study aimed to determine whether a positive L-dimer test result by itself is a sufficient indication to perform a ventilation/perfusion V/Q study. V/Q lung scan results, L-dimer test results and appropriate radiology results of 949 consecutive patients from August 2000 to October 2001 were retrospectively reviewed. Prediction of V/Q results by L-dimer results was compared with that of clinical risk factors for PE (Risk factor + or -) These factors were dyspnoea, current deep vein thrombosis (DVT), recent orthopaedic procedure or a past history of PE/DVT, Of the 949 patients in the study population, 254 patients had an L-dimer study, with 206 positive and 48 negative L-dimer results. Helical CT was performed in 8 patients with an equivocal V/Q - 4 showed PE and 4 did not. In the 27 patients with a positive L-dimer result and PE on either V-Q scan or CT, 25 (92.6%) had additional recognised major risk factors for PE. A positive L-dimer test is a poor predictor of a positive V/Q scan compared to conventional clinical indications. Thus, a positive L-dimer test result in isolation does not constitute an appropriate indication to perform a V/Q scan. Copyright (2002) The Australian and New Zealand Society of Nuclear Medicine Inc

  11. Computer-aided position planning of miniplates to treat facial bone defects.

    Directory of Open Access Journals (Sweden)

    Jan Egger

    Full Text Available In this contribution, a software system for computer-aided position planning of miniplates to treat facial bone defects is proposed. The intra-operatively used bone plates have to be passively adapted on the underlying bone contours for adequate bone fragment stabilization. However, this procedure can lead to frequent intra-operatively performed material readjustments especially in complex surgical cases. Our approach is able to fit a selection of common implant models on the surgeon's desired position in a 3D computer model. This happens with respect to the surrounding anatomical structures, always including the possibility of adjusting both the direction and the position of the used osteosynthesis material. By using the proposed software, surgeons are able to pre-plan the out coming implant in its form and morphology with the aid of a computer-visualized model within a few minutes. Further, the resulting model can be stored in STL file format, the commonly used format for 3D printing. Using this technology, surgeons are able to print the virtual generated implant, or create an individually designed bending tool. This method leads to adapted osteosynthesis materials according to the surrounding anatomy and requires further a minimum amount of money and time.

    2009-07-01

    Full Text Available Abstract Background Many breast cancer patients remain free of distant metastasis even without adjuvant chemotherapy. While standard histopathological tests fail to identify these good prognosis patients with adequate precision, analyses of gene expression patterns in primary tumors have resulted in more successful diagnostic tests. These tests use continuous measurements of the mRNA concentrations of numerous genes to determine a risk of metastasis in lymph node negative breast cancer patients with other clinical traits. Methods A survival model is constructed from genes that are both connected with relapse and have expression patterns that define distinct subtypes, suggestive of different cellular states. This in silico study uses publicly available microarray databases generated with Affymetrix GeneChip technology. The genes in our model, as represented by array probes, have distinctive distributions in a patient cohort, consisting of a large normal component of low expression values; and a long right tail of high expression values. The cutoff between low and high expression of a probe is determined from the distribution using the theory of mixture models. The good prognosis group in our model consists of the samples in the low expression component of multiple genes. Results Here, we define a novel test for risk of metastasis in estrogen receptor positive (ER+ breast cancer patients, using four probes that determine distinct subtypes. The good prognosis group in this test, denoted AP4-, consists of the samples with low expression of each of the four probes. Two probes target MKI67, antigen identified by monoclonal antibody Ki-67, one targets CDC6, cell division cycle 6 homolog (S. cerevisiae, and a fourth targets SPAG5, sperm associated antigen 5. The long-term metastasis-free survival probability for samples in AP4- is sufficiently high to render chemotherapy of questionable benefit. Conclusion A breast cancer subtype defined by low

    Full Text Available The article is devoted to the urgent problem related to the development of the region, namely, the creation of tools for the assessment of the level of social dissatisfaction in the region. The assessment of the level of social dissatisfaction is one of the most important tasks of state organizations in political and social spheres. The article considers the concept of "social dissatisfaction" and associated terms, it substantiates the author's position on the content of this notion. The authors have investigated the existing national and international approaches to the assessing of social tensions of the population. The system of socio-economic development indicators doesn’t contain indicators allowing to assess the level of social dissatisfaction without the results of public polls. We propose two models in the article. In the first model, the assessment is basedon the single factor (the index of social dissatisfaction based on income differentiation. The second complex model takes into account a number of factors (the index of social dissatisfaction based on complex assessment. For the calculation of the proposed indicators, the authors use the statistical data of the Federal State Statistics Service. The methodological research tools include the mathematical methods of statistical data processing. We have evaluated the methodological tools on the example of the Republic of Ingushetia. The assessment has showed the dynamics of a decline in the level of social-economic dissatisfaction in the region (1995–2011. The models of social dissatisfaction constitute a tool for rapid and up-to-date assessment of socio-economic system sustainability, and of the willingness of the population to participate in protests. The application of the results of this study is the support of decision-making regions and state structures in working out plans of the socio-economic development of the regions.

    2011-01-01

    Purpose: Many planning methods for high dose rate (HDR) brachytherapy require an iterative approach. A set of computational parameters are hypothesized that will give a dose plan that meets dosimetric criteria. A dose plan is computed using these parameters, and if any dosimetric criteria are not met, the process is iterated until a suitable dose plan is found. In this way, the dose distribution is controlled by abstract parameters. The purpose of this study is to develop a new approach for HDR brachytherapy by directly optimizing the dose distribution based on dosimetric criteria. Methods: The authors developed inverse planning by integer program (IPIP), an optimization model for computing HDR brachytherapy dose plans and a fast heuristic for it. They used their heuristic to compute dose plans for 20 anonymized prostate cancer image data sets from patients previously treated at their clinic database. Dosimetry was evaluated and compared to dosimetric criteria. Results: Dose plans computed from IPIP satisfied all given dosimetric criteria for the target and healthy tissue after a single iteration. The average target coverage was 95%. The average computation time for IPIP was 30.1 s on an Intel(R) Core TM 2 Duo CPU 1.67 GHz processor with 3 Gib RAM. Conclusions: IPIP is an HDR brachytherapy planning system that directly incorporates dosimetric criteria. The authors have demonstrated that IPIP has clinically acceptable performance for the prostate cases and dosimetric criteria used in this study, in both dosimetry and runtime. Further study is required to determine if IPIP performs well for a more general group of patients and dosimetric criteria, including other cancer sites such as GYN.

  17. Positive behavioral support planning in the inpatient treatment of severe disruptive behaviors: A description of service features.

    Hamlett, Nakia M; Carr, Erika R; Hillbrand, Marc

    2016-05-01

    Positive behavior support (PBS) plans are increasingly used on inpatient units to assess and treat serious and dangerous behaviors displayed by patients with serious psychiatric impairment. A contemporary extension of traditional applied behavior analytic procedures, PBS plans integrate theories from several domains with perspectives on community psychology, positive psychology, and recovery-oriented care. Because there is little evidence to suggest that more invasive, punitive disciplinary strategies lead to long-term positive behavioral change (Parkes, 1996), PBS plans have emerged as an alternative to the use of seclusion and restraint or other forms of restrictive measures typically used on inpatient psychiatric units (Hammer et al., 2011). Moreover, PBS plans are a preferred method of intervention because more invasive interventions often cause more harm than good to all involved (Elliott et al., 2005). This article seeks to provide an integrated framework for the development of positive behavior support plans in inpatient psychiatric settings. In addition to explicating the philosophy and core elements of PBS plans, this work includes discussion of the didactic and pragmatic aspects of training clinical staff in inpatient mental health settings. A case vignette is included for illustration and to highlight the use of PBS plans as a mechanism for helping patients transition to less restrictive settings. This work will add to the scant literature examining the use of positive behavioral support plans in inpatient psychiatric settings. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Buescher, Christian; Hauck, Eckart; Schilberg, Daniel; Jeschke, Sabina

    2012-01-01

    Within the ramp-up phase of highly automated assembly systems, the planning effort forms a large part of production costs. Due to shortening product lifecycles, changing customer demands, and therefore an increasing number of ramp-up processes, these costs even rise. So assembly systems should reduce these efforts and simultaneously be flexible for quick adaption to changes in products and their variants. A cognitive interaction system in the field of assembly planning systems is developed wi...

    Bankoff, Sarah M; McCullough, Mary B; Pantalone, David W

    2013-06-01

    We used secondary data analysis to examine associations among aspects of patient-provider relationships and mental and physical health indicators. Positive patient perceptions of patient-provider relationships were associated with fewer mental health symptoms in this outpatient sample of HIV-positive men who have sex with men (N = 171). Regression analyses revealed the role of anxiety and depression in explaining associations between two aspects of patient-provider relationships (i.e. quality of information offered and provider interactional style) and health-related quality of life. The findings demonstrated the importance of patient-provider relationships to improving physical health and functioning and maintaining engagement in care, among HIV-positive men who have sex with men.

    Full Text Available The international literature offers a numberof motives which should incline local authoritiestoward strategic planning of local development;it also emphasizes that they should be stronglymotivated to do that. Meanwhile, their actualmotivation for such planning can remain low anddominated by motives so far unrecognized in theliterature. The article presents research confi rmingthis assumption, conducted in 2014 amongthe authorities of Polish small towns.The results reveal that the general motivationfor strategic planning of local developmentamong 37.7% of the authorities of Polish smalltowns is low. It also disclosed that the motivefor obtaining means from the EU funds (so farunrecognized in literature was and is motivatingstrongly at least 68.6% of these authorities forthe discussed planning and, moreover, that it is ashort-lived motive. The article indicates that thissituation may also refer to other local authorities,not just the Polish ones. It also indicates that itis an unintended effect of the dependence ofmunicipal development projects’ support by themeans from the EU funds on including them inthe local development strategy. The fi nal part ofthe article presents recommendations of actionsto rectify such an unfavorable situation and forfurther studies of planning motives followed bylocal authorities.

    2015-01-01

    Energy certification of buildings, mandatory under the European Directive EPBD provides interesting data on the thermo-physical properties and geometry of existing buildings. Although the energy certificate is intended to provide the characteristics of individual buildings, so stimulating the real estate market toward ever better energy performance, data management of the certificates issued over time, using a national or regional energy cadastre, makes available a data base which is useful for energy planning in the building sector. This paper provides the needed results of a benchmarking study on data from the energy cadastre of the Lombardy Region, northern Italy. By integrating data from the energy cadastre (175.778 energy certificates) with the statistical data obtained from the national census, indicators were obtained on the energy performance of existing buildings. The energy indicators obtained, characterised by building type and construction period, normalised as a function of Degree-Days, become an effective tool for energy planning at local and regional scales. In the specific case, the energy indicators have been used to estimate the potential for energy retrofit of existing buildings in the Lombardy Region. The same indicators can also be used by municipalities for energy planning at the municipal or district level. -- Highlights: •A methodology in order to obtain energy performance indicators from an energy cadastre. •Data contained in the energy certificates can be used to understand the thermo-physical properties of an existing building. •Energy indicators on existing buildings are used as a tool for energy planning. •The analysis of the energy cadastre (official register) can detect errors in the registered energy certificates. •The energy indicators are used in order to quantify the energy retrofit potential in existing building stocks

    Full Text Available Context: Possible benefits of inverse planning. Aims: To analyze possible benefits of inverse planning intensity modulated radiation therapy (IMRT over field-in-field 3D conformal radiation therapy (FIF-3DCRT and to evaluate the differences if any, between low (6 Million Volts and high energy (15 Million Volts IMRT plans. Materials and Methods: Ten patients with squamous cell carcinoma of oropharynx, previously treated with 6 MV step and shoot IMRT were studied. V 100 , V 33 , V 66 , mean dose and normal tissue complication probabilities (NTCP were evaluated for parotid glands. Maximum dose and NTCP were the parameters for spinal cord. Statistical Analysis Used: A two-tailed t-test was applied to analyze statistical significance between the different techniques. Results: For combined parotid gland, a reduction of 4.374 Gy, 9.343 Gy and 7.883 Gy were achieved for D 100 , D 66 and D 33 , respectively in 6 MV-IMRT when compared with FIF-3DCRT. Spinal cord sparing was better in 6 MV-IMRT (40.963 ± 2.650, with an average reduction of maximum spinal cord dose by 7.355 Gy from that using the FIF-3DCRT technique. The uncomplicated tumor control probabilities values were higher in IMRT plans thus leading to a possibility of dose escalation. Conclusions: Though low-energy IMRT is the preferred choice for treatment of oropharyngeal cancers, FIF-3DCRT must be given due consideration as a second choice for its well established advantages over traditional conventioan technique.

  12. Comparison of Radiation Treatment Plans for Breast Cancer between 3D Conformal in Prone and Supine Positions in Contrast to VMAT and IMRT Supine Positions

    Science.gov (United States)

    Bejarano Buele, Ana Isabel

    The treatment regimen for breast cancer patients typically involves Whole Breast Irradiation (WBI). The coverage and extent of the radiation treatment is dictated by location of tumor mass, breast tissue distribution, involvement of lymph nodes, and other factors. The current standard treatment approach used at our institution is a 3D tangential beam geometry, which involves two fields irradiating the breast, or a four field beam arrangement covering the whole breast and involved nodes, while decreasing the dose to organs as risk (OARs) such as the lung and heart. The coverage of these targets can be difficult to achieve in patients with unfavorable thoracic geometries, especially in those cases in which the planning target volume (PTV) is extended to the chest wall. It is a well-known fact that exposure of the heart to ionizing radiation has been proved to increase the subsequent rate of ischemic heart disease. In these cases, inverse planned treatments have become a proven alternative to the 3D approach. The goal of this research project is to evaluate the factors that affect our current techniques as well as to adapt the development of inverse modulated techniques for our clinic, in which breast cancer patients are one of the largest populations treated. For this purpose, a dosimetric comparison along with the evaluation of immobilization devices was necessary. Radiation treatment plans were designed and dosimetrically compared for 5 patients in both, supine and prone positions. For 8 patients, VMAT and IMRT plans were created and evaluated in the supine position. Skin flash incorporation for inverse modulated plans required measurement of the surface dose as well as an evaluation of breast volume changes during a treatment course. It was found that prone 3D conformal plans as well as the VMAT and IMRT plans are generally superior in sparing OARs to supine plans with comparable PTV coverage. Prone setup leads to larger shifts in breast volume as well as in

    Full Text Available The reasons such as; decrease in forest areas, deterioration in the structure, fragmented structures, decrease in water sources, environmental pollution and increase in carbon level in air are considered as the main sources of problems like global warming and global climate change. Countries have been trying to develop cooperative solutions for these problems since the mid-20th century. Sustainable forest management criteria and indicators, which were outcomes of Biological Diversity Agreement and the processes afterwards, have also been specified in Turkey based on Pan-European process indicators. According to this set of criteria and indicators, data are collected in the scale of Forest Enterprises and the current situation is evaluated in the meetings held by Regional Directorates of Forestry. Most of the data to be evaluated are obtained from forest management plans in the scale of Forest Planning Units and a great deal of economic indicators are dealt in the scale of Forestry Enterprises. Starting from this point of view; this study analyzes the SFM criteria and indicators set data of Saçinka Forest Planning Unit. Accordingly, it examines whether forest ecosystem is conducted in a sustainable way or not.

    2013-01-01

    Full Text Available This study explored barriers to and facilitators of using family planning services among HIV-positive men in Nyanza Province, Kenya. From May to June 2010, in-depth interviews were conducted with 30 men receiving care at 15 HIV clinics. The key barriers to the use of family planning included concerns about side effects of contraceptives, lack of knowledge about contraceptive methods, myths and misconceptions including fear of infertility, structural barriers such as staffing shortages at HIV clinics, and a lack of male focus in family planning methods and service delivery. The integration of family planning into HIV clinics including family planning counseling and education was cited as an important strategy to improve family planning receptivity among men. Integrating family planning into HIV services is a promising strategy to facilitate male involvement in family planning. Integration needs to be rigorously evaluated in order to measure its impact on unmet need for contraception among HIV-positive women and their partners and assure that it is implemented in a manner that engages both men and women.

    A comprehensive Compensation Plan for pharmacy services delivered by community pharmacists was implemented in Alberta, Canada in July 2012. Services covered by the Compensation Plan include care planning services, prescribing services such as adapting prescriptions, and administering a drug or publicly-funded vaccine by injection. Understanding how the Compensation Plan was framed and communicated provides insight into the roles of pharmacists and the potential influence of language on the implementation of services covered by the Compensation Plan by Albertan pharmacists. The objective of this study is to examine the positioning of pharmacists' roles in documents used to communicate the Compensation Plan to Albertan pharmacists and other audiences. Publicly available documents related to the Compensation Plan, such as news releases or reports, published between January 2012 and December 2015 were obtained from websites such as the Government of Alberta, Alberta Blue Cross, the Alberta College of Pharmacists, the Alberta Pharmacists' Association, and the Blueprint for Pharmacy. Searches of the Canadian Newsstand database and Google identified additional documents. Discourse analysis was performed using social positioning theory to explore how pharmacists' roles were constructed in communications about the Compensation Plan. In total, 65 publicly available documents were included in the analysis. The Compensation Plan was put forward as a framework for payment for professional services and formal legitimization of pharmacists' changing professional roles. The discourse associated with the Compensation Plan positioned pharmacists' roles as: (1) expanding to include services such as medication management for chronic diseases, (2) contributing to primary health care by providing access to services such as prescription renewals and immunizations, and (3) collaborating with other health care team members.

    2014-10-01

    Full Text Available The web has been used for years as a means of expression for the local communities in highlighting their problems, needs and hopes, often in the form of organized group discussions and fora. The enormous amount of information currently available, Big Data, is already used for business purposes in the private sector, but has never been truly available to decision makers who operate in urban planning and would represent an invaluable help for those communities that undertake the path of selfconstruction of their Community Strategic Frameworks. This paper elaborates methodological and operational proposals to identify sequences of words and common occurrences in sets of documents that would help understanding the problems of the communities on a geographicallylocated basis, creating the search engine “Social Debate” and devising new indicators for indices of disadvantage. Such tool could drastically change the perspective of public participation and planning practice and improve the quality of local public policies and decision making processes.

    Purpose: The aim of the present work was to explore plan quality and dosimetric accuracy of intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) for lymph node-positive left-sided breast cancer. Methods: VMAT and IMRT plans were generated with the Pinnacle{sup 3} V9.0 treatment planning system for 10 lymph node-positive left-sided breast cancer patients. VMAT plans were created using a single arc and IMRT was performed with 4 beams using 6, 10, and 15 MV photon energy, respectively. Plans were evaluated both manually and automatically using ArtiView trademark. Dosimetric plan verification was performed with a 2D ionization chamber array placed in a full scatter phantom. Results: Photon energy had no significant influence on plan quality for both VMAT and IMRT. Large variability in low doses to the heart was found due to patient anatomy (range V{sub 5} {sub Gy} 26.5-95 %). Slightly more normal tissue dose was found for VMAT (e.g., V{sub Tissue30%} = 22 %) than in IMRT (V{sub Tissue30%} = 18 %). The manual and ArtiView trademark plan evaluation coincided very accurately for most dose metrics (difference < 1 %). In VMAT, 96.7 % of detector points passed the 3 %/3 mm gamma criterion; marginally better accuracy was found in IMRT (98.3 %). Conclusion: VMAT for node-positive left-sided breast cancer retains target homogeneity and coverage when compared to IMRT and allows maximum doses to organs at risk to be reduced. ArtiView trademark enables fast and accurate plan evaluation. (orig.)

    Autoimmune Addison's disease (AAD) associates with exceptional susceptibility to develop other autoimmune conditions, including type 1 diabetes (T1D), marked by positive serum autoantibodies to insulin (IAA), glutamic acid decarboxylase (GADA) and insulinoma-associated protein 2 (IA-2A). Zinc transporter 8 (ZnT8) is a new T1D autoantigen, encoded by the SLC30A8 gene. Its polymorphic variant rs13266634C/T seems associated with the occurrence of serum ZnT8 antibodies (ZnT8A). This study was designed to determine the prevalence of serum ZnT8A and their clinical implication in 140 AAD patients. Other beta cell and thyroid-specific autoantibodies were also investigated, and ZnT8A results were confronted with the rs13266634 genotype. ZnT8A were detectable in 8.5 %, GADA in 20.7 %, IA-2A in 5.7 %, IAA in 1.6 % and various anti-thyroid antibodies in 7.1-67.8 % individuals. Type 1 diabetes was found in 10 % AAD patients. ZnT8A were positive in 57.1 % of T1D patients and 3.4 % non-diabetic AAD. Analysis of ZnT8A enabled to identify autoimmunity in two (14.3 %) T1D individuals previously classified as autoantibody-negative. ZnT8A-positive patients revealed significantly higher number of autoimmune conditions (p < 0.001), increased prevalence of T1D (p < 0.001) and other beta cell-specific autoantibodies. Carriers of the rs13266634 T-allele displayed increased frequency (p = 0.006) and higher titres of ZnT8A (p = 0.002). Our study demonstrates high incidence of ZnT8A in AAD patients. ZnT8A are associated with coexisting T1D and predictive of T1D in non-diabetic subjects. Moreover, positive ZnT8A in AAD indicate elevated risk for additional autoimmune conditions. Autoantibodies to beta cell antigens, comprising ZnT8, could be included in routine screening panels in AAD.

  5. A validation of 11 body-condition indices in a giant snake species that exhibits positive allometry.

    Bryan G Falk

    Full Text Available Body condition is a gauge of the energy stores of an animal, and though it has important implications for fitness, survival, competition, and disease, it is difficult to measure directly. Instead, body condition is frequently estimated as a body condition index (BCI using length and mass measurements. A desirable BCI should accurately reflect true body condition and be unbiased with respect to size (i.e., mean BCI estimates should not change across different length or mass ranges, and choosing the most-appropriate BCI is not straightforward. We evaluated 11 different BCIs in 248 Burmese pythons (Python bivittatus, organisms that, like other snakes, exhibit simple body plans well characterized by length and mass. We found that the length-mass relationship in Burmese pythons is positively allometric, where mass increases rapidly with respect to length, and this allowed us to explore the effects of allometry on BCI verification. We employed three alternative measures of 'true' body condition: percent fat, scaled fat, and residual fat. The latter two measures mostly accommodated allometry in true body condition, but percent fat did not. Our inferences of the best-performing BCIs depended heavily on our measure of true body condition, with most BCIs falling into one of two groups. The first group contained most BCIs based on ratios, and these were associated with percent fat and body length (i.e., were biased. The second group contained the scaled mass index and most of the BCIs based on linear regressions, and these were associated with both scaled and residual fat but not body length (i.e., were unbiased. Our results show that potential differences in measures of true body condition should be explored in BCI verification studies, particularly in organisms undergoing allometric growth. Furthermore, the caveats of each BCI and similarities to other BCIs are important to consider when determining which BCI is appropriate for any particular taxon.

In Mozambique, the prevalence of HIV among women of reproductive age is 13.1% and the average fertility rate is high. However, family planning and reproductive health for WLHIV are under-addressed in Mozambique. This study explores provider descriptions of reproductive health messages in order to identify possible barriers and facilitators to successfully addressing family planning and pregnancy concerns of WLHIV. Methods: In 2006, a Positive Health, Dignity, and Prevention program was introduced in Mozambique focused on training health care providers to work with patients to reduce their transmission risks. Providers received training on multiple components, including family planning and prevention of mother-to-child transmission (PMTCT. In-depth interviews were conducted with 31 providers who participated in the training in five rural clinics in three provinces. Data were analyzed using qualitative content analysis. Results: Analysis showed that providers' clinical messages on family planning, pregnancy, and PMTCT for WLHIV could be arranged along a continuum. Provider statements ranged from saying that WLHIV should not become pregnant and condoms are the only valid form of family planning for WLHIV, to suggesting that WLHIV can have safe pregnancies. Conclusion: These data indicate that many providers continue to believe that WLHIV should not have children and this represents a challenge for integrating family planning into the care of WLHIV. Also, not offering WLHIV a full selection of family planning methods severely limits their ability to protect themselves from unintended pregnancies and to fully exercise their reproductive rights.

    Full text: The positional accuracy of multileaf collimators (MLC) is crucial in ensuring precise delivery of intensity-modulated radiotherapy (IMRT). The aim of this planning study was to investigate the dosimetric impact of systematic MLC positional errors on step and shoot IMRT of prostate cancer. A total of 12 perturbations of MLC leaf banks were introduced to six prostate IMRT treatment plans to simulate MLC systematic positional errors. Dose volume histograms (DVHs) were generated for the extraction of dose endpoint parameters. Plans were evaluated in terms of changes to the defined endpoint dose parameters, conformity index (CI) and healthy tissue avoidance (HTA) to planning target volume (PTV), rectum and bladder. Negative perturbations of MLC had been found to produce greater changes to endpoint dose parameters than positive perturbations of MLC (p 9 5 of -1.2 and 0.9% respectively. Negative and positive synchronised MLC perturbations of I mm in one direction resulted in median changes in D 9 5 of -2.3 and 1.8% respectively. Doses to rectum were generally more sensitive to systematic MLC en-ors compared to bladder (p < 0.01). Negative and positive synchronised MLC perturbations of I mm in one direction resulted in median changes in endpoint dose parameters of rectum and bladder from 1.0 to 2.5%. Maximum reduction of -4.4 and -7.3% were recorded for conformity index (CI) and healthy tissue avoidance (HT A) respectively due to synchronised MLC perturbation of 1 mm. MLC errors resulted in dosimetric changes in IMRT plans for prostate. (author)

    Glenoid component positioning is a key factor for success in total shoulder arthroplasty. Three-dimensional (3D) measurements of glenoid retroversion, inclination, and humeral head subluxation are helpful tools for preoperative planning. The purpose of this study was to assess the reliability and precision of a novel surgical method for placing the glenoid component with use of patient-specific templates created by preoperative surgical planning and 3D modeling. A preoperative computed tomography examination of cadaveric scapulae (N = 18) was performed. The glenoid implants were virtually placed, and patient-specific guides were created to direct the guide pin into the desired orientation and position in the glenoid. The 3D orientation and position of the guide pin were evaluated by performing a postoperative computed tomography scan for each scapula. The differences between the preoperative planning and the achieved result were analyzed. The mean error in 3D orientation of the guide pin was 2.39°, the mean entry point position error was 1.05 mm, and the mean inclination angle error was 1.42°. The average error in the version angle was 1.64°. There were no technical difficulties or complications related to use of patient-specific guides for guide pin placement. Quantitative analysis of guide pin positioning demonstrated a good correlation between preoperative planning and the achieved position of the guide pin. This study demonstrates the reliability and precision of preoperative planning software and patient-specific guides for glenoid component placement in total shoulder arthroplasty. Copyright © 2015.

    Hypermethylation of the suppressor of cytokine signaling 3(SOCS3) promoter has been reported to predict a poor prognosis in several cancers including glioblastoma multiforme (GBM). We explored the function of SOCS3 promoter hypermethylation in GBM cohorts, including analysis of the CpG island methylator phenotype (CIMP), when a large number of gene loci are simultaneously hypermethylated. A whole genome promoter methylation profile was performed in a cohort of 33 GBM samples, with 13 long-term survivors (LTS; overall survival ≥ 18 months) and 20 short-term survivors (STS; overall survival ≤ 9 months). The SOCS3 promoter methylation status was compared between the two groups. In addition, we investigated the relationship of SOCS3 promoter methylation and G-CIMP status. Interestingly, in our present study, we found that SOCS3 promoter methylation was statistically significantly higher in the 13 LTS than that in the 20 STS. Furthermore, high SOCS3 promoter methylation detected via pyro-sequencing predicted a better prognosis in an independent cohort containing 62 GBM patients. This correlation was validated by the dataset from the Cancer Genome Atlas(TCGA) and the Chinese Cancer Genome Atlas(CGGA). In addition, we found that hypermethylation of the SOCS3 promoter was tightly associated with the G-CIMP-positive GBM patients. Using a total of 359 clinical samples, we demonstrate that SOCS3 promoter hypermethylation status has a favorable prognostic value in GBM patients because of whole genome methylation status. Particularly, the hypermethylation of the SOCS3 promoter indicates positive G-CIMP status.

    This article, Part 1 of the Endocrine Society of Australia's position statement on male hypogonadism, focuses on assessment of male hypogonadism, including the indications for testosterone therapy. (Part 2 will deal with treatment and therapeutic considerations.) Key points and recommendations are:Pathological hypogonadism arises due to diseases of the hypothalamus or pituitary gland (hypogonadotropic hypogonadism) or testes (hypergonadotropic hypogonadism). It is a clinical diagnosis with a pathological basis, confirmed by hormone assays.Hormonal assessment is based on measurement of circulating testosterone, luteinising hormone (LH) and follicle-stimulating hormone (FSH) concentrations. Measurement of sex hormone-binding globulin levels can be informative, but use of calculated free testosterone is not recommended for clinical decision making.Testosterone replacement therapy is warranted in men with pathological hypogonadism, regardless of age.Currently, there are limited data from high-quality randomised controlled trials with clinically meaningful outcomes to justify testosterone treatment in older men, usually with chronic disease, who have low circulating testosterone levels but without hypothalamic, pituitary or testicular disease.Obesity, metabolic syndrome and type 2 diabetes are associated with lowering of circulating testosterone level, but without elevation of LH and FSH levels. Whether these are non-specific consequences of non-reproductive disorders or a correctable deficiency state is unknown, but clear evidence for efficacy and safety of testosterone therapy in this setting is lacking.Glucocorticoid and opioid use is associated with possibly reversible reductions in circulating testosterone level, without elevation of LH and FSH levels. Where continuation of glucocorticoid or opioid therapy is necessary, review by an endocrinologist may be warranted.Changes in management as result of the position statement: Men with pathological hypogonadism should

    Purpose: CT based treatment planning for transperineal prostate implants allows for angulation of transperineal needles to avoid the pubic bones by changing the template angle. It requires fluoroscopic guidance and utilizes identification of the urethra by radiopaque markers inside the Foley catheter at the time of the implant. The needle trajectory is relative to the urethral angle as visualized by lateral fluoroscopic views. Patients who have a treatment planning CT in preparation for a transperineal prostate implant are typically scanned in the leg-down/straight position. However, the implant is done in the lithotomy position and changes in the template angle to adapt to the new urethral angle are often required. We have evaluated the relationship between leg position and the position of the prostatic urethra to predict the change in the planned template angle. Material and Methods: To duplicate the lithotomy position a custom designed foot holder was constructed that attached to a flatbed CT scanner. A Foley catheter was inserted with radio-opaque contrast placed in the balloon. Bladder contrast was also utilized. A catheter with 1 cm spaced dummy seeds was placed inside the Foley catheter. A radio-opaque catheter was inserted into the rectum. Fifteen patients had pre-implant scans performed in the leg-down/straight and lithotomy position. The prostate, urethra, bladder and rectum were contoured utilizing a 3D-brachytherapy software system and analyzed. Results: Fourteen of the patients (93%) had changes in urethral angle when evaluated in the lithotomy relative to the led-down/straight position. The mean angle change was - 9.8 degrees (Std. Error 1.47 degrees; p < 0.0001) when in the lithotomy position. The changes were not correlated with prostatic volume or clinical stage. All patients who had urethral angle changes would have required adjustments in the template angle. Conclusions: 1) The objective of treatment planning for prostate implants is to

    Full Text Available Current transportation planning processes often incorporate public input, but the types of engagement techniques can affect the ability of practitioners to meaningfully include local ideas. This study incorporates literature integrating communicative rationality with participatory mapping, supported by a case study focusing on two public engagement techniques. A transportation planning process in Central Texas is evaluated in terms of the geographic specificity and positionality of comments received from open-ended responses on a questionnaire and a facilitated mapping session, and reviews this input for relevance to developing a transportation plan. Although all input received from the public can be valuable in the process, location-based comments may be more actionable by transportation planners. Participants’ perceived roles likely affect their level of engagement, which planners can facilitate to maximize the quality of involvement. Planners are advised to understand the positionality of project stakeholders and professionals, designing involvement methods considering geographic specificity appropriate for each project.

    Conclusions This study showed a transient increase of ocular vestibular evoked myogenic potential (oVEMP) amplitudes in the affected ear after successful liberatory maneuvers and no changes in cervical VEMP (cVEMP) amplitudes. These findings support the hypothesis that successful liberatory maneuvers can lead to a repositioning of otoconia to the utricle. Objectives To evaluate whether oVEMP amplitudes increase after successful liberatory maneuvers in patients with posterior semicircular canal benign paroxysmal positioning vertigo (pc-BPPV), while cVEMP amplitudes do not change. These findings may indicate a successful repositioning of dislodged otoconia to the utricular macula, but not to the saccular macula. Methods Thirty patients with unilateral pc-BPPV were prospectively examined with bone-conducted oVEMP and air-conducted cVEMP at four time points: before, after, 1 week after, and 1 month after the liberatory maneuvers (Sémont maneuvers). Results At the 1-week follow-up, 20 of 30 patients were asymptomatic (responders); BPPV could still be induced in the other 10 (non-responders). In responders the mean n10 amplitude on the affected side increased from 12 ± 6.5 μV at baseline (before the treatment) to 15.9 ± 7.1 μV at 1 week after treatment; this increase was significantly (p = 0.001) higher in responders than in non-responders. cVEMP did not differ significantly.

    Full Text Available SLIT ( sublingual immunotherapy induces allergen-specific immune tolerance by sublingual administration of a gradually increasing dose of an allergen. The mechanism of SLIT is comparable to those during SCIT (subcutaneous immunotherapy, with the exception of local oral dendritic cells, pre-programmed to elicit tolerance. In the SLIT dose, to achieve the same efficacy as in SCIT, it should be 50–100 times higher with better safety profile. The highest quality evidence supporting the efficacy of SLIT lasting 1 – 3 years has been provided by the large scale double-blind, placebo-controlled (DBPC trials for grass pollen extracts, both in children and adults with allergic rhinitis. Current indications for SLIT are allergic rhinitis (and conjunctivitis in both children and adults sensitized to pollen allergens (trees, grass, Parietaria , house dust mites ( Dermatophagoides pteronyssinus, Dermatophagoides farinae , cat fur, as well as mild to moderate controlled atopic asthma in children sensitized to house dust mites. There are positive findings for both asthma and new sensitization prevention. Severe adverse events, including anaphylaxis, are very rare, and no fatalities have been reported. Local adverse reactions develop in up to 70 – 80% of patients. Risk factors for SLIT adverse events have not been clearly identified. Risk factors of non-adherence to treatment might be dependent on the patient, disease treatment, physician-patient relationship, and variables in the health care system organization.

    Purpose: To evaluate the feasibility of using helical tomotherapy for locally advanced left-sided breast cancer. Methods and Materials: Treatment plans were generated for 10 left-sided breast cancer patients with positive lymph nodes comparing a multiport breast (three-dimensional) technique with the tomotherapy treatment planning system. The planning target volumes, including the chest wall/breast, supraclavicular, axillary, and internal mammary lymph nodes, were contoured. The treatment plans were generated on the tomotherapy treatment planning system to deliver 50.4 Gy to the planning target volume. To spare the contralateral tissues, directional blocking was applied to the right breast and right lung. The optimization goals were to protect the lungs, heart, and right breast. Results: The tomotherapy plans increased the minimal dose to the planning target volume (minimal dose received by 99% of target volume = 46.2 ± 1.3 Gy vs. 27.9 ± 17.1 Gy) while improving the dose homogeneity (dose difference between the minimal dose received by 5% and 95% of the planning target volume = 7.5 ± 1.8 Gy vs. 37.5 ± 26.9 Gy). The mean percentage of the left lung volume receiving ≥20 Gy in the tomotherapy plans decreased from 32.6% ± 4.1% to 17.6% ± 3.5%, while restricting the right-lung mean dose to <5 Gy. However, the mean percentage of volume receiving ≥5 Gy for the total lung increased from 25.2% ± 4.2% for the three-dimensional technique to 46.9% ± 8.4% for the tomotherapy plan. The mean volume receiving ≥35 Gy for the heart decreased from 5.6% ± 4.8% to 2.2% ± 1.5% in the tomotherapy plans. However, the mean heart dose for tomotherapy delivery increased from 7.5 ± 3.4 Gy to 12.2 ± 1.8 Gy. Conclusion: The tomotherapy plans provided better dose conformity and homogeneity than did the three-dimensional plans for treatment of left-sided breast tumors with regional lymph node involvement, while allowing greater sparing of the heart and left lung from doses

    2012-07-01

    In the context of increasing greenhouse gas emission and global demographic change with the simultaneous trend to urbanization, it is a big challenge for cities around the world to perform modifications in energy supply chain and building characteristics resulting in reduced energy consumption and carbon dioxide mitigation. Sound knowledge of energy resource demand and supply including its spatial distribution within urban areas is of great importance for planning strategies addressing greater energy efficiency. The understanding of the city as a complex energy system affects several areas of the urban living, e.g. energy supply, urban texture, human lifestyle, and climate protection. With the growing availability of 3D city models around the world based on the standard language and format CityGML, energy system modelling, analysis and simulation can be incorporated into these models. Both domains will profit from that interaction by bringing together official and accurate building models including building geometries, semantics and locations forming a realistic image of the urban structure with systemic energy simulation models. A holistic view on the impacts of energy planning scenarios can be modelled and analyzed including side effects on urban texture and human lifestyle. This paper focuses on the identification, classification, and integration of energy-related key indicators of buildings and neighbourhoods within 3D building models. Consequent application of 3D city models conforming to CityGML serves the purpose of deriving indicators for this topic. These will be set into the context of urban energy planning within the Energy Atlas Berlin. The generation of indicator objects covering the indicator values and related processing information will be presented on the sample scenario estimation of heating energy consumption in buildings and neighbourhoods. In their entirety the key indicators will form an adequate image of the local energy situation for

  20. Indicators of abdominal size relative to height associated with sex, age, socioeconomic position and ancestry among US adults.

    The supine sagittal abdominal diameter (SAD) and standing waist circumference (WC) describe abdominal size. The SAD/height ratio (SADHtR) or WC/height ratio (WHtR) may better identify cardiometabolic disorders than BMI (weight/height2), but population-based distributions of SADHtR and WHtR are not widely available. Abdominal adiposity may differ by sociodemographic characteristics. Anthropometry, including SAD by sliding-beam caliper, was performed on 9894 non-pregnant adults ≥20 years in the US National Health and Nutrition Examination Surveys of 2011-2014. Applying survey design factors and sampling weights, we estimated nationally representative SADHtR and WHtR distributions by sex, age, educational attainment, and four ancestral groups. The median (10th percentile, 90th percentile) for men's SADHtR was 0.130 (0.103, 0.165) and WHtR 0.569 (0.467, 0.690). For women, median SADHtR was 0.132 (0.102, 0.175) and WHtR 0.586 (0.473, 0.738). Medians for SADHtR and WHtR increased steadily through age 79. The median BMI, however, reached maximum values at ages 40-49 (men) or 60-69 (women) and then declined. Low educational attainment, adjusted for age and ancestry, was associated with elevated SADHtR more strongly than elevated BMI. While non-Hispanic Asians had substantially lower BMI compared to all other ancestral groups (adjusted for sex, age and education), their relative reductions in SADHtR and WHtR, were less marked. These cross-sectional data are consistent with monotonically increasing abdominal adipose tissue through the years of adulthood but decreasing mass in non-abdominal regions beyond middle age. They suggest also that visceral adipose tissue, estimated by SADHtR, expands differentially in association with low socioeconomic position. Insofar as Asians have lower BMIs than other populations, employing abdominal indicators may attenuate the adiposity differences reported between ancestral groups.

    We recently reported distinct nature of high-density lipoproteins (HDL) subgroup particles with apolipoprotein (apo) A-I but not apoA-II (LpAI) and HDL having both (LpAI:AII) based on the data from 314 Japanese. While plasma HDL level almost exclusively depends on concentration of LpAI having 3 to 4 apoA-I molecules, LpAI:AII appeared with almost constant concentration regardless of plasma HDL levels having stable structure with two apoA-I and one disulfide-dimeric apoA-II molecules (Sci. Rep. 6; 31,532, 2016). The aim of this study is further characterization of LpAI:AII with respect to its role in atherogenesis. Association of LpAI, LpAI:AII and other HDL parameters with apoB-lipoprotein parameters was analyzed among the cohort data above. ApoA-I in LpAI negatively correlated with the apoB-lipoprotein parameters such as apoB, triglyceride, nonHDL-cholesterol, and nonHDL-cholesterol + triglyceride, which are apparently reflected in the relations of the total HDL parameters to apoB-lipoproteins. In contrast, apoA-I in LpAI:AII and apoA-II positively correlated to the apoB-lipoprotein parameters even within their small range of variation. These relationships are independent of sex, but may slightly be influenced by the activity-related CETP mutations. The study suggested that LpAI:AII is an atherogenic indicator rather than antiatherogenic. These sub-fractions of HDL are to be evaluated separately for estimating atherogenic risk of the patients.

  2. Examination of CT-AEC when the positioning changes after planning of CT scanning

    2009-01-01

    CT-automatic exposure control (AEC) controls tube current collecting information of the subject from positioning shooting. Because of this, we consider that CT-AEC does not get to operate properly if the body position of the test subject changes after the positioning shooting. However, we often experience in body positions of test subjects after the positioning shooting. In cases like this, we measured by using a phantom again to see how they affect the tube current value and standard deviation (SD) value comparing them to the normal scan where a body position does not change. As a result of the measurement, there was an impact on CT-AEC that optimization of tube current becomes insufficient if the body position of a test subject changes. As the image quality is deteriorated and radiation exposure increases because of this, taking positioning shooting again is required on the part of users and it's desirable on the part of manufacturers to develop CT-AEC that can be controlled with high accuracy.

    1990-06-01

    The mission statement of a prominent California hospital has been revised as part of a strategic planning process less than two years before the hospital began experiencing substantial financial difficulties. When the "red numbers" began to appear, management was quick to blame changing demographic patterns and the competitive environment. Those were not the only problems. A major contributing factor that management failed to recognize was a delay in how quickly the hospital moved to adopt high technology or new medical procedures. In a few short years, it had changed from being the first community hospital to implement state-of-the-art programs to one that was slow to introduce technology. In retrospect, the hospital's mission statement did not address the role of technology and therefore it could not detect the movement away from one of its critical success factors. The Rotec Theory was developed to assist this hospital to understand the economics of technology on its current and planned operations.

    2008-06-01

    Reduction of ineffective parenting is promoted in parent training components of mental health treatment for children with externalizing behavior disorders, but minimal research has considered whether disciplinary style and lower abuse risk could also be associated with positive functioning in such children. The present study examined whether lower dysfunctional disciplinary style and child abuse risk was associated with children's positive self-concept, adaptive attributional style, and hopefulness. Recruited from children undergoing treatment for disruptive behavior disorders, 69 mother-child dyads participated, with maternal caregivers reporting on their disciplinary style and abuse potential and children reporting independently on their positive functioning (adaptive attributional style, overall self-concept, and hopelessness). Findings supported the hypothesized association, with lower scores on mothers' dysfunctional discipline style and abuse potential significantly predicting children's reported positive functioning. Future research directions pertaining to more adaptive functioning in children with behavior problems are discussed.

    For user-friendliness, many software systems offer progress indicators for long-duration tasks. A typical progress indicator continuously estimates the remaining task execution time as well as the portion of the task that has been finished. Building a machine learning model often takes a long time, but no existing machine learning software supplies a non-trivial progress indicator. Similarly, running a data mining algorithm often takes a long time, but no existing data mining software provides a nontrivial progress indicator. In this article, we consider the problem of offering progress indicators for machine learning model building and data mining algorithm execution. We discuss the goals and challenges intrinsic to this problem. Then we describe an initial framework for implementing such progress indicators and two advanced, potential uses of them, with the goal of inspiring future research on this topic. PMID:29177022

    Health resort programs have a long tradition, mainly in European countries and Japan. They rely on local resources and the physical environment, physical medicine interventions and traditional medicine to optimise functioning and health. Arguably because of the long tradition, there is only a limited number of high-quality studies that examine the effectiveness of health resort programs. Specific challenges to the evaluation of health resort programs are to randomise the holistic approach with a varying number of specific interventions but also the reliance on the effect of the physical environment. Reference standards for the planning and reporting of health resort studies would be highly beneficial. With the International Classification of Functioning Disability and Health (ICF), we now have such a standard that allows us to describe body functions and structures, activities and participation and interaction with environmental factors. A major challenge when applying the ICF in practice is its length. Therefore, the objective of this project was to identify the ICF categories most relevant for health resort programs. We conducted a consensus-building, three-round, e-mail survey using the Delphi technique. Based on the consensus of the experts, it was possible to come up with an ICF Core Set that can serve as reference standards for the indication, intervention planning and evaluation of health resort programs. This preliminary ICF Core Set should be tested in different regions and in subsets of health resort visitors with varying conditions.

    This study estimated the epidemiological and financial indicators of hypertension in order to identify challenges in strategic planning and management for health systems in Latin America. This is a longitudinal study with a population base of 187 326 reported cases of older adults with hypertension, diagnosed at public health institutions in Mexico. The cost-evaluation method that was used was based on the instrumentation and consensus techniques. To estimate the epidemiological changes and financial consequences for 2015-2017, time series analyses and probabilistic models were constructed according to the Box-Jenkins technique. Regarding epidemiological changes for 2015 versus 2017, an increase of 8-12% is expected (p financial requirements. The total amount estimated for hypertension in 2015 (in US dollars) was $1 575 671 330. It included $747 527 259 as direct costs and $829 144 071 as indirect costs. If the risk factors and the different healthcare services for older adults remain as they are currently, the financial consequences of epidemiological changes in older adults will have a major impact on the users' pockets, following in order of importance, on social security providers and on public assistance providers. The challenges and implications of our findings in the context of universal coverage reforms in Latin America reinforce the urgent need to develop more and better strategic planning for the prevention of chronic diseases.

    2014-01-01

    ABSTRACT Lack of appropriate human resources planning is an important factor in the inefficient use of the public health facilities. Workforce projections can be improved by using objective methods of staffing needs based on the workload and actual work undertaken by workers, a guideline developed by Peter J. Shipp in collaboration with WHO—Workload Indicators of Staffing Need (WISN). A cross-sectional study was carried out to estimate the nursing stuff requirement for the rural hospitals and provide a quantitative description of imbalances, if there is any, in the allocation at the district level during 2011. The average WISN turns out to be 0.35 for entire district, which means only 35% of the required nurses is available or 65% understaffed. So, there is an urgent need for more allocations and deployment of staff so that workload can be tackled and evenly distributed among all nursing personnel. PMID:25895199

    The Quasi-Zenith satellites System (QZSS) is developed as an integrated satellite service system of communication, broadcasting and positioning for mobile users in specified regions of Japan from high elevation angle. Purposes of the satellite positioning system using Quasi-Zenith satellite (QZS) are to complement and augment the GPS. The national institutes concerned have been developing the positioning system using QZS since 2003 and will carry out experiments and researches in three years after the launch. In this system, National Institute of Information and Communications Technology (NICT) is mainly in charge of timing system for the satellite positioning system using QZS, such as onboard hydrogen maser atomic clock and precise time management system of the QZSS. We started to develop the engineering model of the time management system for the QZSS. The time management system for the QZSS will be used to compare time differences between QZS and earth station as well as to compare between three onboard atomic clocks. This paper introduces time management of satellite positioning system using the QZSS.

    Full text: The positional accuracy of multi leaf collimators (MLC) is crucial in ensuring precise delivery of intensity-modulated radiotherapy (IMRT). The aim of this planning study was to investigate the dosimetric impact of systematic MLC errors on step and shoot IMRT of prostate cancer. Twelve MLC leaf banks perturbations were introduced to six prostate IMRT treatment plans to simulate MLC systematic errors. Dose volume histograms (OYHs) were generated for the extraction of dose endpoint parameters. Plans were evaluated in terms of changes to the defined endpoint dose parameters, conformity index (CI) and healthy tissue avoidance (HTA) to planning target volume (PTY), rectum and bladder. Negative perturbations of MLC had been found to produce greater changes to endpoint dose parameters than positive perturbations of MLC (p < 0.05). Negative and positive synchronized MLC perturbations of I mm resulted in median changes of -2.32 and 1.78%, respectively to 095% of PTY whereas asynchronized MLC perturbations of the same direction and magnitude resulted in median changes of 1.18 and 0.90%, respectively. Doses to rectum were generally more sensitive to systematic MLC errors compared to bladder. Synchronized MLC perturbations of I mm resulted in median changes of endpoint dose parameters to both rectum and bladder from about I to 3%. Maximum reduction of -4.44 and -7.29% were recorded for CI and HTA, respectively, due to synchronized MLC perturbation of I mm. In summary, MLC errors resulted in measurable amount of dose changes to PTY and surrounding critical structures in prostate LMRT. (author)

    Full Text Available Background and Objectives: The amount of physical activity as an essential determinant of healthy lifestyle in females is less than is required. Theory-driven health education interventions, particularly Theory of Planned Behavior (TPB, are effective in promoting and sustaining physical activity. This research evaluated the TPB-based educational intervention on exercise behavior and anthropometric indices in females residing in organizational houses in Tehran. Materials and Methods: A randomized controlled trial was performed on 130 females residing in institutional houses in Tehran (2014. Participants were randomly chosen with multi-stage cluster sampling. The instructional sessions were carried out applying modified methods of the TPB structure (instrumental and affective attitudes, subjective norms, perceived behavioral control, intention and behavior. The TPB constructs, physical activity level and intensity, Body Mass Index (BMI and Waist Hip Ratio (WHR were analyzed using the SPSS 16software in baseline, three and six months post-education. Results: Conducting the educational program led to a rise and maintained the mean of the TPB constructs and mean rank of the physical activity level and intensity, three and six months post-intervention in the case group (P0.05 Conclusions: Implementing the TPB-directed instructional sessions resulted in ameliorating and sustaining exercise behavior and anthropometric indices in females.

  20. Implication of spot position error on plan quality and patient safety in pencil-beam-scanning proton therapy

    Purpose: To quantitatively and systematically assess dosimetric effects induced by spot positioning error as a function of spot spacing (SS) on intensity-modulated proton therapy (IMPT) plan quality and to facilitate evaluation of safety tolerance limits on spot position. Methods: Spot position errors (PE) ranging from 1 to 2 mm were simulated. Simple plans were created on a water phantom, and IMPT plans were calculated on two pediatric patients with a brain tumor of 28 and 3 cc, respectively, using a commercial planning system. For the phantom, a uniform dose was delivered to targets located at different depths from 10 to 20 cm with various field sizes from 2{sup 2} to 15{sup 2} cm{sup 2}. Two nominal spot sizes, 4.0 and 6.6 mm of 1 σ in water at isocenter, were used for treatment planning. The SS ranged from 0.5 σ to 1.5 σ, which is 2–6 mm for the small spot size and 3.3–9.9 mm for the large spot size. Various perturbation scenarios of a single spot error and systematic and random multiple spot errors were studied. To quantify the dosimetric effects, percent dose error (PDE) depth profiles and the value of percent dose error at the maximum dose difference (PDE [ΔDmax]) were used for evaluation. Results: A pair of hot and cold spots was created per spot shift. PDE[ΔDmax] is found to be a complex function of PE, SS, spot size, depth, and global spot distribution that can be well defined in simple models. For volumetric targets, the PDE [ΔDmax] is not noticeably affected by the change of field size or target volume within the studied ranges. In general, reducing SS decreased the dose error. For the facility studied, given a single spot error with a PE of 1.2 mm and for both spot sizes, a SS of 1σ resulted in a 2% maximum dose error; a SS larger than 1.25 σ substantially increased the dose error and its sensitivity to PE. A similar trend was observed in multiple spot errors (both systematic and random errors). Systematic PE can lead to noticeable hot

    The aim of this study was to define, retrospectively, the utility to perform (99m)Tc-EDDA/HYNIC-Tyr3-octreotide ((99m)Tc-EDDA/HYNIC-TOC) scan in patients with NET. We studied 50 consecutive patients affected by different types of NET and divided in two groups. Group 1: 34 patients with known lesions in which (99m)Tc-EDDA/HYNIC-TOC was performed for staging, characterisation or to choose the appropriate treatment. Group 2: 16 patients suspected of having NET or in follow up after surgery. Patients were injected with 370 MBq of (99m)Tc-EDDA/HYNIC-Tyr3-octreotide and whole-body and SPET images acquired 2-3 hours after injection. Overall, 29 patients (58%) had a positive scan, with a sensitivity, specificity and accuracy of 70.3%, 76.9% and 72%, respectively (78.1%, 50% and 76.5%, in group 1 and 20%, 81.2%, 62.5% in group 2). In patients from group 1 (99m)Tc-HYNIC-TOC scintigraphy showed a concordance of 68% with another imaging procedure and in 9 patients revealed a greater number of lesions. In the second group, false negative results were especially found in patients with medullary thyroid cancer with negative radiological findings and elevated calcitonin. In conclusion, (99m)Tc-EDDA/HYNIC-TOC is highly indicated for in vivo histological characterization of known NET lesions, previously identified by other imaging modalities or biopsy, to plan appropriate therapy especially for patients with inoperable disease. In patients with only biochemical suspicion of NET and in those with negative markers, this scintigraphy does not significantly modify the clinical management.

    Although HIV is now cast as a chronic condition with favourable clinical outcomes under new treatments, it is unclear how living with HIV affects expectations and planning for the future. This mixed-methods study aimed to investigate UK gay men's expectations of their own future when living with HIV, and to identify the heath and social interventions required to enhance roles, participation and personal fulfilment. A preliminary focus group identified relevant domains of enquiry for a subsequent online cross-sectional survey. A total of 347 gay men living in the UK with HIV participated in the survey, and 56.6% were currently on treatment. However, high 7-day prevalence of psychological and physical symptoms was identified (42.6% in pain, 80.2% worrying); 57.8% perceived reduced career options due to their infection and 71.8% reduced life expectancy. Being on treatment was not significantly associated with perceived life expectancy. Coded open-ended survey data identified eight principle themes related to goal planning and attainment. The integrated open and closed data items offer an understanding of barriers and challenges that focus on poor mental health due to clinical inattention, discrimination and stigma, poor career and job opportunities due to benefit and workplace inflexibility and lack of understanding, a lack of personal goals and associated skills deficit related to confidence and self esteem. Gay men living with HIV require an integrated holistic approach to wellbeing that incorporates clinical, social and individual intervention in order to lead productive lives with maximum benefit from treatment gains.

    We sought to estimate the prevalence of rape-related pregnancy as an indication for abortion at two public Chicago facilities and to describe demographic and clinical correlates of women who terminated rape-related pregnancies. We performed a cross-sectional study of women obtaining abortion at the Center for Reproductive Health (CRH) at University of Illinois Health Sciences Center and Reproductive Health Services (RHS) at John H. Stroger, Jr. Hospital between August 2009 and August 2013. Gestational age limits at CRH and RHS were 23+6 and 13+6weeks, respectively. We estimated the prevalence of rape-related pregnancy based on billing code (CRH) or data from an administrative database (RHS), and examined relationships between rape-related pregnancy and demographic and clinical variables. Included were 19,465 visits for abortion. The majority of patients were Black (85.6%). Prevalence of abortion for rape-related pregnancy was 1.9%, and was higher at CRH (6.9%) than RHS (1.5%). Later gestational age was associated with abortion for rape-related pregnancy (median 12days, prape-related pregnancy at CRH only (prape-related pregnancy than among those terminating for other indications. Rape-related pregnancy as an indication for abortion had a low, but clinically significant prevalence at two urban Chicago family planning centers. Later gestational age was associated with abortion for rape-related pregnancy. Rape-related pregnancy may occur with higher prevalence among some subgroups of women seeking abortion than others. Efforts to address rape-related pregnancy in the abortion care setting are needed. Copyright © 2015 Elsevier Inc. All rights reserved.

CONCLUSION: The study identified social inequalities in oral health even in a population of independently living, generally healthy very old Swedes...

  6. Selective‐logging and oil palm: multitaxon impacts, biodiversity indicators, and trade‐offs for conservation planning.

    Strong global demand for tropical timber and agricultural products has driven large-scale logging and subsequent conversion of tropical forests. Given that the majority of tropical landscapes have been or will likely be logged, the protection of biodiversity within tropical forests thus depends on whether species can persist in these economically exploited lands, and if species cannot persist, whether we can protect enough primary forest from logging and conversion. However, our knowledge of the impact of logging and conversion on biodiversity is limited to a few taxa, often sampled in different locations with complex land-use histories, hampering attempts to plan cost-effective conservation strategies and to draw conclusions across taxa. Spanning a land-use gradient of primary forest, once- and twice-logged forests, and oil palm plantations, we used traditional sampling and DNA metabarcoding to compile an extensive data set in Sabah, Malaysian Borneo for nine vertebrate and invertebrate taxa to quantify the biological impacts of logging and oil palm, develop cost-effective methods of protecting biodiversity, and examine whether there is congruence in response among taxa. Logged forests retained high species richness, including, on average, 70% of species found in primary forest. In contrast, conversion to oil palm dramatically reduces species richness, with significantly fewer primary-forest species than found on logged forest transects for seven taxa. Using a systematic conservation planning analysis, we show that efficient protection of primary-forest species is achieved with land portfolios that include a large proportion of logged-forest plots. Protecting logged forests is thus a cost-effective method of protecting an ecologically and taxonomically diverse range of species, particularly when conservation budgets are limited. Six indicator groups (birds, leaf-litter ants, beetles, aerial hymenopterans, flies, and true bugs) proved to be consistently good

  7. Examination of the Locus of Positional Effects on Children's Production of Plural -s: Considerations From Local and Global Speech Planning.

    Prosodic and articulatory factors influence children's production of inflectional morphemes. For example, plural -s is produced more reliably in utterance-final compared to utterance-medial position (i.e., the positional effect), which has been attributed to the increased planning time in utterance-final position. In previous investigations of plural -s, utterance-medial plurals were followed by a stop consonant (e.g., dogsbark), inducing high articulatory complexity. We examined whether the positional effect would be observed if the utterance-medial context were simplified to a following vowel. An elicited imitation task was used to collect productions of plural nouns from 2-year-old children. Nouns were elicited utterance-medially and utterance-finally, with the medial plural followed by either a stressed or an unstressed vowel. Acoustic analysis was used to identify evidence of morpheme production. The positional effect was absent when the morpheme was followed by a vowel (e.g., dogseat). However, it returned when the vowel-initial word contained 2 syllables (e.g., dogsarrive), suggesting that the increased processing load in the latter condition negated the facilitative effect of the easy articulatory context. Children's productions of grammatical morphemes reflect a rich interaction between emerging levels of linguistic competence, raising considerations for diagnosis and rehabilitation of language disorders.

    Human papillomavirus (HPV) infection, especially HPV-16 and HPV-18, has been increasingly associated with head and neck squamous cell carcinoma. The treatment of HPV-positive squamous cell carcinoma has a better response to both radiotherapy and chemotherapy and presents a better prognosis for the patient. Defining the underlying mechanism of the difference might help in developing future treatment options and could be an important factor in personal therapy planning. Endogenously secreted acid sphingomyelinase (ASMase) levels in the cellular stress caused by irradiation and cisplatin were investigated. MTT assay was performed to evaluate the viability of the treated cells. Keratinocytes were used to evaluate the effects of radiation on normal tissues. Irradiation caused a dose-dependent increase in ASMase activity in both SCC9 HPV-negative, and UDSCC2 HPV-positive cells. ASMase activity in UDSCC2 cells was significantly higher than that in SCC9 cells. UDSCC cells were more sensitive to cisplatin treatment than SCC cells, and the dose-response in the activity was observed in long-time treatments when high doses of cisplatin were used. The results of the current study have clearly showed that HPV positivity should be considered as one of the determinative factors which should be considered when tumor treatments are planned. However, further studies are needed to determine the differences in cellular responses and pathways among HPV-negative and HPV-positive cells.

  9. Proposal of performance indicators/model for Operational Readiness Verification (ORV) at restart after a planned shutdown

    2005-12-01

    The objectives of the study reported here were to propose a model that can be used in the analysis of possible future ORV-related events and to outline a set of performance indicators that can be used by the inspectorate to assess a utility's level of readiness if an ORV-event should take place. Together the two objectives serve to improve the inspectorate's ability to ensure that the utilities maintain an adequate capability to respond. The background for the current study is the nine ORV events that occurred in Sweden between 1995- 1998, as well as the findings of a previous study of safety during outage and restart of nuclear power plants project. This study found that the three levels or types of tests that occur in ORV were used according to need rather than according to a predefined arrangement or procedure, and that tasks were adapted relative to the different types of embedding and the degree of correspondence between nominal and actual ORV. The organisation's coping with the complexity of ORV was discussed by the relation between expectations and surprises, how planning was used as control, attention to details, and the practices of shift changes. It is a truism that accidents are analysed and interpreted relative to a commonly accepted understanding of their nature. This understanding is, however, relative rather than absolute, and has changed significantly during the last decade. In the 1990s, accidents were analysed step by step, and explanations and recommendations therefore emphasised specific rather than generic solutions. The present study illustrates this by going through the responses to the nine ORV events. Following that, the nine events are analysed anew using a contemporary understanding of accidents (a systemic model), which emphasises that incidents more often arise from context induced performance variability than from failures of people. The alternative interpretation provided by a systemic model is illustrated by a detailed analysis of

    Purpose: The indication for postmastectomy radiotherapy (PMRT) in breast cancer patients with one to three positive lymph nodes has been in discussion. The purpose of this study was to identify patient groups for whom PMRT may be indicated, focusing on varied locoregional recurrence rates depending on lymphatic invasion (ly) status. Methods and Materials: Retrospective analysis of 1,994 node-positive patients who had undergone mastectomy without postoperative radiotherapy between January 1990 and December 2000 at our hospital was performed. Patient groups for whom PMRT should be indicated were assessed using statistical tests based on the relationship between locoregional recurrence rate and ly status. Results: Multivariate analysis showed that the ly status affected the locoregional recurrence rate to as great a degree as the number of positive lymph nodes (p < 0.001). Especially for patients with one to three positive nodes, extensive ly was a more significant factor than stage T3 in the TNM staging system for locoregional recurrence (p < 0.001 vs. p = 0.295). Conclusion: Among postmastectomy patients with one to three positive lymph nodes, patients with extensive ly seem to require local therapy regimens similar to those used for patients with four or more positive nodes and also seem to require consideration of the use of PMRT.

    Purpose. - The dose distribution for lung tumour is estimated using a 3D-CT scan, and since a person breathes while the images are captured, the dose distribution doesn't reflect the reality. A 4D-CT scan integrates the motion of the tumour during breathing and, therefore, provides us with important information regarding tumour's motion in all directions, the motion volume (ITV) and the time-weighted average position (MVP). Patient and methods. - Based on these two concepts, we have estimated, for a lung carcinoma case a 3D dose distribution from a 3D-CT scan, and a 4D dose distribution from a 4-D CT scan. To this, we have applied a non-rigid registration to estimate the cumulative dose. Results. - Our study shows that the 4D dose estimation of the GTV is almost the same when made using MVP and ITV concepts, but sparring of the healthy lung is better done using the MPV model (MVP), as compared to the ITV model. This improvement of the therapeutic index allows, from a projection on the theoretical maximal dose to PTV (strictly restricted to doses for the lungs and the spinal cord), for an increase of about 11% on the total dose (maximal dose of 86 Gy for the ITV and 96 Gy for the MVP). Conclusion. - Further studies with more patients are needed to confirm our data. (authors)

    NASA was quick to realize the potential that the Global Positioning System (GPS) had to offer for its many diverse vehicles, experiments and platforms. Soon after the first Block 1 GPS satellites were launched, NASA began to use the tremendous capabilities that they had to offer. Even with a partial GPS constellation in place, important results have been obtained about the shape, orientation and rotation of the earth and calibration of the ionosphere and troposphere. These calibrations enhance geophysical science and facilitate the navigation of interplanetary spacecraft. Some very important results have been obtained in the continuing NASA program for aircraft terminal area operations. Currently, a large amount of activity is being concentrated on real time kinematic carrier phase tracking which has the potential to revolutionize aircraft navigation. This year marks the launch of the first GPS receiver equipped earth-orbiting NASA spacecraft: the Extreme Ultraviolet Explorer and the Ocean Topography Experiment (TOPEX/Poseidon). This paper describes a cross section of GPS-based research at NASA.

    Full Text Available The apnea hypopnea index (AHI reported by positive airway pressure (PAP device is widely used in clinical practice, yet its correlation with standardized AHI obtained during the sleep study is not established. The current study was conducted to investigate the correlation between AHI estimated by the PAP device and reported on the smart card with the AHI found during the PAP polysomnography (PSG in the "real world" setting at an academic sleep center. We retrospectively reviewed the medical records of 280 patients who underwent a PAP titration PSG at Drexel sleep center, and were later prescribed a PAP device. The AHI was categorized in clinically relevant subgroups (as AHI ≤5 and AHI >5. The AHI at the final pressure on the PSG and the average AHI from the prescribed PAP device were compared. The results showed that in the majority (77.3% of patients (126 of 163, the AHI from both PAP device and PSG correlated well and were in the same category (AHI ≤5 and AHI >5 respectively. The majority of patients (80.7% with PSG AHI of 5, 61.5% patients reported good control, with AHI <5 on PAP device AHI. We conclude that in a majority of patients who were optimally titrated in the sleep laboratory, the PAP device continued to show optimal control at home.

    The purpose of this study was to evaluate neck control outcomes after definitive radiochemotherapy without planned neck dissection in node-positive head and neck cancer. We retrospectively reviewed medical records of fifty patients with node-positive head and neck cancer who received definitive radiochemotherapy. Twelve patients subsequently underwent neck dissection for suspicious recurrent or persistent disease. A median dose of 70 Gy (range 60-70.6) was delivered to involved nodes. Response evaluation was performed at a median of 5 weeks after completion of radiotherapy. Neck failure was observed in 11 patients and the 3-year regional control (RC) rate was 77.1%. Neck dissection was performed in 10 of the 11 patients; seven of these cases were successfully salvaged, and the ultimate rate of neck control was 92%. The remaining two patients who received neck dissection had negative pathologic results. On univariate analysis, initial nodal size > 2 cm, a less-than-complete response at the primary site, post-radiotherapy nodal size > 1.5 cm, and post-radiotherapy nodal necrosis were associated with RC. On multivariate analysis, less-than-complete primary site response and post-radiotherapy nodal necrosis were identified as independent prognostic factors for RC. The neck failure rate after definitive radiochemotherapy without planned neck dissection was 22%. Two-thirds of these were successfully salvaged with neck dissection and the ultimate neck control rate was 92%. Our results suggest that planned neck dissection might not be necessary in patients with complete response of primary site, no evidence of residual lesion > 1.5 cm, or no necrotic lymph nodes at the 1-2 months follow-up evaluation after radiotherapy

    A social determinants approach proposes that enhancing living conditions in areas such as income, housing, transportation, employment, education, social support, and health services is central to improving the health of urban populations. Urban development projects can be costly but have health impacts. The benefit derived from the creation of man-made lakes in developing countries is usually associated with great risks; however, the evidence for physical and non-physical health benefits of urban man-made lake is unclear. The aim of this paper is to formulate a conceptual framework of associations between urban man-made lakes and social determinants of health. This study was a qualitative study carried out using one focus group discussion and 16 individual interviews. Data were analyzed based on deductive-inductive content analysis approach. Participants' points of view were analyzed within 261 codes. Data analysis matrix was the conceptual framework of social determinants of health commission and its sub-groups, thus, two structural and mediating determinants categories as well as their sub-sets were created accordingly. In addition, some extra sub-sets including environment, air quality, weather changes, noise pollution, pathogenesis, quality of life, shortage of available resources, region popularity, ethnicity, tourism, social and physical development of children, unintentional injuries, aesthetic, and spirituality were extracted beyond the matrix factors, which were placed in each of above categories based on their thematic content. This paper has illustrated that the quality and type of man-made lake provided within communities can have a significant and sustained impact on community's health and wellbeing. Therefore, in order to strengthen positive effects and reduce negative effects of any developmental projects within community, their impacts on public health should be taken into consideration.

    Genetic similarities between patients from the United States and South African (SA) Addison's Disease (AD) strengthen evidence for genetic association. SA-AD (n = 73), SA healthy controls (N = 78), and US-AD patients (N = 83) were genotyped for DQA1, DQB1, DRB1, and HLA-B alleles. Serum was tested for the quantity of 21OH-AA and IFNα-AA at the Barbara Davis Center. Although not as profound as in US-AD, in SA-AD 21OH-AA + subjects the predominantly associated risk haplotypes were DRB1*0301-DQB1*0201 (DR3), DRB1*04xx-DQB1*0302 (DR4), and the combined DR3/4 genotype. DQB1*0302 associated DRB1*04xx haplotypes conferred higher risk than those DRB1*04xx haplotypes associated with other DQB1 alleles. We found negative association in 21OH-AA + SA-AD for DQA1*0201-DQB1*0202 and DQA1*0101-DQB1*0501 vs SA controls, and positive association for DQA1*0401-DQB1*0402 vs US-AD. Apart from the class II DR3 haplotype, HLA-B8 did not have an independent effect; however together DR3 and HLA-B8 conferred the highest risk vs 21OH-AA negative SA-AD and SA-controls. HLA-B7 (often with DR4) conferred novel risk in 21OH-AA + SA-AD vs controls. This study represents the first comparison between South African and United States AD populations utilizing genotyping and serology performed at the same center. SA-AD and US-AD 21OH-AA + patients share common HLA risk haplotypes including DR4 (with HLA-B7) and DR3 (with HLA-B8), strengthening previously described HLA associations and implicating similar genetic etiology. © 2014 John Wiley & Sons A/S.

    Individuals should aim to adjust their parental behaviours in order to maximize the success of their offspring but minimize associated costs. Plasticity in parental care is well documented from various bird, mammal and fish species, whereas amphibians were traditionally assumed as being highly instinct-bound. Therefore, little is known about 'higher' cognitive abilities of amphibians, such as strategic planning and behavioural flexibility. Dendrobatid frogs have evolved a remarkable diversity of parental behaviours. The most noticeable of these behaviours is tadpole transport, which is obligatory in almost all species. Nonetheless, there is limited knowledge about spatial and temporal patterns of tadpole transport and the possible existence of behavioural plasticity on the individual level. In this study, we investigated correlates of tadpole transport behaviour in a natural population of the dendrobatid frog Allobates femoralis during five years. Tadpole transport was predominantly observed during morning hours. Although tadpoles were carried almost exclusively by males (N = 119), we also observed ten females performing this task. The parentage analysis revealed that in all cases females transported their own offspring. In contrast, four tadpole-carrying males were not the genetic fathers of the larvae they were transporting. The average clutch size of 20 eggs and our observation of an average of 8 tadpoles on the back of transporting individuals indicate that frogs do not carry entire clutches at once, and/or that they distribute their larvae across several water bodies. Contrary to the predictions from a hypothetical random search for deposition sites, the number of transported tadpoles was higher in males that travelled over longer distances. Our results suggest a strong selective pressure on males to shift the time invested in tadpole transport to periods of low intra-specific competition. The number of tadpoles on the back of the males significantly

    The Centers for Disease Control and Prevention and Healthy People 2020 call for improvements in meeting men's reproductive health needs but little is known about the proportion of men in need. This study describes men aged 35 to 39 in need of family planning and preconception care, demographic correlates of these needs, and contraception use among men in need of family planning. Using data from Wave 4 (2008-2010) of the National Survey of Adolescent Males, men were classified in need of family planning and preconception care if they reported sex with a female in the last year and believed that they and their partner were fecund; the former included men who were neither intentionally pregnant nor intending future children and the latter included men intending future children. Men were classified as being in need of both if they reported multiple sex partners in the past year. About 40% of men aged 35 to 39 were in need of family planning and about 33% in need of preconception care with 12% in need of both. Current partner's age, current union type, and sexually transmitted infection health risk differentiated men in need of family planning and preconception care (all ps family planning reported none of the time current partner hormonal use (55%) or condom use (52%) during the past year. This study identified that many men in their mid-30s are in need of family planning or preconception care. © The Author(s) 2014.

    Purpose: To compare biophysical indices of Volumetric Modulated Arc Therapy (VMAT) and Intensity Modulated Radiation Therapy (IMRT) treatment plans for whole brain radiation therapy following the NRG-CC001 protocol. Methods: In this retrospective study, a total of fifteen patients were planned with Varian Eclipse Treatment Planning System using VMAT (RapidArc) and IMRT techniques. The planning target volume (PTV) was defined as the whole brain volume excluding a uniform three-dimensional 5mm expansion of the hippocampus volume. Prescribed doses in all plans were 30 Gy delivered over 10 fractions normalized to a minimum of 95% of the target volume receiving 100% of the prescribed dose. The NRG Oncology protocol guidelines were followed for contouring and dose-volume constraints. A single radiation oncologist evaluated all treatment plans. Calculations of statistical significance were performed using Student’s paired t-test. Results: All VMAT and IMRT plans met the NRG-CC001 protocol dose-volume criteria. The average equivalent uniform dose (EUD) for the PTV for VMAT vs. IMRT was respectively (19.05±0.33 Gy vs. 19.38±0.47 Gy) for α/β of 2 Gy and (19.47±0.30 Gy vs. 19.84±0.42 Gy) for α/β of 10 Gy. For the PTV, the average mean and maximum doses were 2% and 5% lower in VMAT plans than in IMRT plans, respectively. The average EUD and the normal tissue complication probability (NTCP) for the hippocampus in VMAT vs. IMRT plans were (15.28±1.35 Gy vs. 15.65±0.99 Gy, p=0.18) and (0.305±0.012 Gy vs. 0.308±0.008 Gy, p=0.192), respectively. The average EUD and NTCP for the optic chiasm were both 2% higher in VMAT than in IMRT plans. Conclusion: Though statistically insignificant, VMAT plans indicate a lower hippocampus EUD than IMRT plans. Also, a small variation in NTCP was found between plans.

    We describe rates of unintended pregnancy among HIV positive couples in Lusaka, Zambia. We also identify factors associated with unintended pregnancy among oral contraceptive pill (OCP) using couples in this cohort. Data were analyzed from couples randomized in a factorial design to two family planning intervention videos. Rates of unintended pregnancy were stratified by contraceptive method used at time of pregnancy. Predictors of time to unintended pregnancy among OCP users were determined via multivariate Cox modeling. The highest rates of unintended pregnancy were observed among couples requesting condoms only (26.4/100CY) or OCPs (20.7/100CY); these rates were not significantly different. OCP users accounted for 37% of the couple-years (CY) observed and 87% of unintended pregnancies. Rates of unintended pregnancy for injectable (0.7/100CY) and intrauterine device (1.6/100CY) users were significantly lower relative to condom only users. No pregnancies occurred among contraceptive implant users or after tubal ligation. Factors associated (psex without a condom. Long-acting reversible contraceptive methods were effective in the context of integrated couples HIV prevention and contraceptive services. Injectable methods were also effective in this context. Given the high user failure rate of OCPs, family planning efforts should promote longer-acting methods among OCP users wishing to avoid pregnancy. Where other methods are not available or acceptable, OCP adherence counseling is needed, especially among younger and new OCP users. ClinicalTrials.gov NCT00067522.

    Purpose: To investigate the relationship between the conformality index (CIn), heterogeneity index (HIn), and gradient index (GIn) and the development of toxicity in patients treated with Gamma Knife radiosurgery (GKRS) for intracranial meningiomas. Methods and Materials: Treatment records of patients treated from 1997 to 2009 with at least 6 months of follow-up were reviewed. The following parameters were collected: CIn, HIn, GIn (ratio of the volume receiving half the prescription isodose to the volume receiving the full prescription isodose), brainstem (BS) maximum dose (MD), BS volume receiving ≥12 Gy (V12), optic apparatus (OA) MD, OA V8 Gy, OA V10, number of isocenters, number of isocenters outside target volume, and the occurrence of six toxicities. Univariate and multivariate logistic regression modeling were used for analysis. Results: This study included 145 patients (148 meningiomas) with a median follow-up time of 27 months (range, 6–113.9 months). The majority of meningiomas were located in the skull base (53%). The median prescription dose was 13 Gy (range, 10–24 Gy) to the 51.50% (range, 50–92%) isodose. A lower HIn was correlated with a higher GIn (p = 0.007). CIn was not associated with any toxicity. Higher HIn was associated with the development of dizziness (odds ratio [OR] 1.9; p = 0.02), whereas a lower GIn was associated with motor deficits (OR 0.38; p = 0.04) and auditory changes (OR 0.59; p = 0.04). The OA MD, V8, and V12 were not associated with visual changes, but visual changes were associated with a higher number of isocenters outside the target volume (OR 1.93; p = 0.07). BS V12 was correlated with the development of auditory changes (OR 1.05; p = 0.05), whereas patients with higher BS MD tended to have increased toxicity. Conclusions: Close attention must be paid to all three indices (CIn, HIn, GIn) when optimal treatment plans are determined. We recommend that the target CIn should be ≤2.0, the HIn ≤2.0, and the GIn ≥3

The primary planning target volume (PTVP and boost planning target volume (PTVB were contoured. The total prescription dose was 78 Gy (56 Gy to PTVP and an additional 22 Gy to PTVB. For all cases, treatment plans using 6MV with FB and FFF beams with identical dose-volume constraints, arc angles and number of arcs were developed. The dose volume histograms for both techniques were compared for primary target volume and critical structures.Results: A low Sigma index (FFF: 1.65 + 0.361; FB: 1.725 + 0.39 indicating improved dose homogeneity in FFF beam. Conformity index (FFF: 0.994 + 0.01; FB: 0.993 + 0.01 is comparable for both techniques. Minimal difference of Organ at risk mean dose was observed. Normal tissue integral dose in FB plan resulted 1.5% lower than FFF plan. All the plans displayed significant increase (1.18 times for PTVP and 1.11 for PTBB in the average number of necessary MU with FFF beam.Conclusion: Diversity between FB and FFF beam plans were found.

    Introduction: Indications for postmastectomy radiation include primary tumor size ≥5 cm and/or ≥4 positive axillary nodes. In clinical practice, patients with a close or positive margin after mastectomy are also often treated with postmastectomy radiation. However, there is little data regarding the risk of a chest wall recurrence in patients with close or positive margins who otherwise would be considered low risk (tumor size 50 (p = 0.04). There was no correlation with chest wall failure and number of positive nodes, ER status, lymphovascular invasion, location of primary, grade, family history, or type of tumor close to the margin. Of 5 chest wall failures, 4 were in patients who had received adjuvant systemic chemotherapy ± tamoxifen. Chest wall failures occurred in 1 patient with a positive deep margin, 3 patients with margins within 2 mm, and 1 patient with a margin of 5 mm. The estimated cumulative incidence probability of chest wall recurrence at 8 years by margin proximity was 24% ≤ 2 mm vs. 7% 2.1-6 mm (p = 0.36), and by clinical size 24% for T2 tumors vs. 7% for T1 (p = 0.98). Conclusions: A close or positive margin is uncommon (≤5%) after mastectomy in patients with tumor size <5 cm and 0-3 positive axillary nodes but, when present, it appears to be in a younger patient population. The subgroup of patients aged 50 or younger with clinical T1-T2 tumor size and 0-3 positive nodes who have a close (≤5 mm) or positive mastectomy margin are at high risk (28% at 8 years) for chest wall recurrence regardless of adjuvant systemic therapy and, therefore, should be considered for postmastectomy radiation

    Community health planning requires identification of the level of access to care and factors which affect the differentials in use of health services. In formulating strategies or alternatives for planning, some assessment of the current level or patterns of health services must be made. It is this element of the planning process that is addressed in this paper. In this study sixty-five specifically designated areas (medical market areas) in the Province of Quebec, Canada were selected. The analysis was performed using data obtained from a large scale study of physicians' responses to the introduction of universal medical care insurance in Quebec. Our analysis offered an opportunity to observe the impact of Medicare on access to care for those thought to be underserved.

    Minimal residual disease (MRD) monitoring via quantitative PCR (qPCR) detection of Ag receptor gene rearrangements has been the most sensitive method for predicting prognosis and making post-transplant treatment decisions for patients with ALL. Despite the broad clinical usefulness and standardization of this method, we and others have repeatedly reported the possibility of false-positive MRD results caused by massive B-lymphocyte regeneration after stem cell transplantation (SCT). Next-generation sequencing (NGS) enables precise and sensitive detection of multiple Ag receptor rearrangements, thus providing a more specific readout compared to qPCR. We investigated two cohorts of children with ALL who underwent SCT (30 patients and 228 samples). The first cohort consisted of 17 patients who remained in long-term CR after SCT despite having low MRD positivity (SCT monitoring using qPCR. Only one of 27 qPCR-positive samples was confirmed to be positive by NGS. Conversely, 10 of 15 samples with low qPCR-detected MRD positivity from 13 patients who subsequently relapsed were also confirmed to be positive by NGS (P=0.002). These data show that NGS has a better specificity in post-SCT ALL management and indicate that treatment interventions aimed at reverting impending relapse should not be based on qPCR only.

    This cross-sectional study investigated whether the theory of planned behavior (TPB) constructs: attitudes, subjective norms, and perceived behavioral control were related to intention of dietary supplements use among African-American women living with Human Immunodeficiency Virus and/or Acquired Immune Deficiency Syndrome (HIV/AIDS). A closed-ended questionnaire based on the TPB was utilized to explore the use of dietary supplements among a cohort of 153 HIV-positive African-American women. Overall, 45% of the respondents used dietary supplements to manage/control their HIV. Combined, attitudes, subjective norms and perceived behavioral control were significant predictors of intention toward dietary supplement use (69% of the variance explained, pbehavioral control (β=0.45, pBehavioral intention and proximal TPB constructs (attitudes, subjective norms, and perceived behavioral control), as well as their underlying beliefs about dietary supplements use, were all found to be significantly more positive in users of dietary supplements compared to non-users (pbehavioral control are important predictors in the intention to use dietary supplements for control of HIV among African-American women. Implications from this study suggest that the TPB can be used to better identify and understand salient beliefs that surround intentions to use alternative therapies for management of disease. These beliefs can be used to develop interventions surrounding HIV treatment and care. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available This paper examines two indicators, namely the net monetary statement and the net non-monetary statement. To determine and analyze them, we started with the classification of assets (monetary and non-monetary and liabilities (monetary and nonmonetary. The actual values of these elements were established on the basis of information supplied by the balance sheet, followed by the calculus of the net monetary statement and of the net non-monetary statement. These indicators provide relevant and reliable information to the users of financial statements and, in the future, they should be taken into account because they bring additional information about the financial position of the entity.

    The purpose of the study was to investigate the relationships between the Myers-Briggs Type Indicator (MBTI) psychological type and marital satisfaction, divorce proneness, positive affect, and conflict regulation in couple visiting a clinic. Couples (n=62) who visited "M" couple clinic participated in the study. Data were collected from March to June 2009 using the Marital Satisfaction Scale, Marital Status Inventory, Positive Affect Inventory, and Conflict Regulation Inventory. The couples showed no significant differences in marital satisfaction, positive affect, and conflict regulation according to similarities between spouses in MBTI types. However, they showed significant differences in divorce proneness of husband according to a similarity in the Sensing/Intuition indicator. They also showed significant differences in divorce proneness, positive affect, and conflict regulation between the couples for ISTJ (Introversion, Sensing, Thinking, Judging) or ESTJ (Extraversion, Sensing, Thinking, Judging) types compared to other couples. When nurses counsel couples, they should understand that differences in psychological type between spouses affects their marital relationship. In addition, nurses should educate couples on the characteristics of each type according to the couple's types and help them to understand each other, especially for couples where one spouse is the ISTJ/ESTJ type. These interventions will improve marital satisfaction and prevent the divorce in these couples.

    The purpose of the test was to verify that the AN Tank Farm Manifold Valves can be manually manipulated to the required operating position and that the electrical and visual indications accurately reflect that position. Physical locking devices were also verified to function. The Acceptance Test Procedure HNF-4642, 241-AN-A Valve Pit Manifold Valves and Position Indication was conducted between 23 June and 10 August 1999 at the 200E AN Tank Farm. The test has no open test exceptions. The test was conducted prior to final engineering ''as built'' activities being completed, this had an impact on the procedure and test results, ECN 653752 was written to correct the mismatch between the procedure and actual field conditions. P and ID H-14-100941 was changed via ECN-W-314-4C-120. All components, identified in the procedure, were not found to be labeled and identified as written in the procedure, temporary tags were used for operational identification. A retest of valve ANA-WT-V 318 was required because it was removed from its installed position and modified after testing was completed

    There is limited understanding of ethnic inequalities in doctor-patient communication regarding personal care plans (PCPs). This study investigated the mediating effects of positive mental wellbeing on differences in PCP-related doctor-patient communication amongst South Asian and Caucasian UK residents. Data from 10,980 respondents to the 2013 Health Survey for England was analysed using bootstrapping methods. Constructs from the WEMWBS (Warwick and Edinburgh Mental Wellbeing Scale) (Stewart-Brown, S., and K. Janmohamed. 2008. Warwick, UK) were assessed as mediators of relations between ethnicity and several doctor-patient communication variables, including PCP-related interactions; (a) had a PCP-related discussion about a long-term condition with a doctor/nurse, and (b) had this conversation within the past year, (c) agreed to a PCP with a health professional; and (d) talked to a doctor in the past 2 weeks. Bootstrapped mediation analysis (Hayes, A. F. 2013. Introduction to Mediation, Moderation, and Conditional Process Analysis: A Regression-based Approach. New York, NY: The Guilford Press) showed that three positive mind-sets mediated associations between ethnicity and doctor-patient contact, including PCP-related communication. Being able to make up one's mind (ab = -0.05; BC a CI [-0.14, 0.01]) mediated the effect of ethnicity on agreeing to a PCP, while having energy to spare (ab = 0.07; BC a CI [-0.04, 0.12]), and feeling good about oneself (ab = 0.03; BC a CI [0.01, 0.07]), mediated ethnic effects on talking to a doctor during the past fortnight. The mediating effect of reported energy persisted after controlling for medical history, perceived health, and other covariates. Ethnic disparities in doctor-patient interaction, including PCP-related communication, are partly explained by positive mental wellbeing. Gauging positive psychological moods in patients, particularly self-worth, self-perceived vigour and decisiveness, are relevant to

    Implementing a comprehensive approach to decreasing tobacco use in a large health plan requires hard work and commitment on the part of many individuals. We found that major organisational change can be accomplished and sustained. Keys to our success included our decision to remove access barriers to our cessation programmes (including cost); obtaining top leadership buy-in; identifying accountable individuals who owned responsibility for change; measuring key processes and outcomes; and finally keeping at it tenaciously through multiple cycles of improvement.

    This document outlines a ground-water monitoring plan for the 216-B-63 trench located in the northeast corner of the 200-East Area on the Hanford Site in southeastern Washington State. It has been determined that hazardous materials (corrosives) were disposed of to the trench during past operations. Installation of an interim-status ground-water monitoring system is required to determine whether hazardous chemicals are leaching to the ground water from beneath the trench. This document summarizes the existing data that are available from near the 216-B-63 trench and presents a plan to determine the extent of ground-water contamination, if any, derived from the trench. The plan calls for the installation of four new monitoring wells located near the west end of the trench. These wells will be used to monitor ground-water levels and water quality immediately adjacent to the trench. Two existing RCRA monitoring wells, which are located near the trench and hydraulically upgradient of it, will be used as background wells. 46 refs., 15 figs., 12 tabs

  16. A close or positive margin after mastectomy is not an indication for chest wall irradiation except in women aged fifty or younger

    Purpose: Indications for postmastectomy radiation include primary tumor size > 5 cm and ≥ 4 positive axillary nodes. In clinical practice, patients with a close or positive margin after mastectomy are also often treated with postmastectomy radiation. However, there is little data regarding the risk of a chest wall recurrence in patients with this pathologic feature who otherwise would be considered low risk (tumor size 25% at 8 years: Age ≤ 50 years was 28% vs. 0% for age > 50 (p=0.08). There was no correlation with chest wall failure and number of nodes, ER status, lymphovascular invasion, location of primary, grade, family history or type of tumor close to the margin. All four chest wall failures were in patients who had received adjuvant systemic chemotherapy ± Tamoxifen. Chest wall failures occurred in patients with margins within 1-2 mm in three patients and 5 mm in one patient. The cumulative chest wall recurrence at 8 years by margin proximity was 24% ≤ 2mm vs. 7% 2.1-6 mm (p=0.44), and by clinical size 24% for T2 tumors vs. 7% for T1 (p=0.55). Conclusions: A close or positive margin is uncommon (< 5%) after mastectomy in patients with tumor size < 5 cm and 0-3 positive axillary nodes, but when present it appears to be in a younger patient population. The subgroup of patients aged 50 or younger with clinical T1-T2 tumor size and 0-3 positive nodes who have a close (≤ 5 mm) or positive mastectomy margin are at high risk (28% at 8 years) for chest wall recurrence regardless of adjuvant systemic therapy, and therefore we recommend they be considered for postmastectomy radiation. This high risk of local failure was not observed in patients over age 50, suggesting this subgroup may not require adjuvant chest wall irradiation

    Purpose: Magnetic resonance imaging (MRI) guidance in radiation therapy brings real-time imaging and adaptive planning into the treatment vault where it can account for interfraction and intrafraction movement of soft tissue. The only commercially available MRI-guided radiation therapy device is a three-head {sup 60}Co and MRI system with an integrated treatment planning system (TPS). Couch attenuation of the beam of up to 20% is well modeled in the TPS. Variations in the patient’s day-to-day position introduce discrepancies in the actual couch attenuation as modeled in the treatment plan. For this reason, the authors’ institution avoids plans with beams that pass through or near the couch edges. This study investigates the effects of differential beam attenuation by the couch due to couch shifts in order to determine whether couch edge avoidance restrictions can be lifted. Couch shifts were simulated using a Monte Carlo treatment planning system and ion chamber measurements performed for validation. Methods: A total of 27 plans from 23 patients were investigated. Couch shifts of 1 and 2 cm were introduced in combinations of lateral and vertical directions to simulate patient position variations giving 16 shifted plans per reference plan. The 1 and 2 cm shifts were based on shifts recorded in 320 treatment fractions. Results: Following TG176 recommendations for measurement methods, couch attenuation measurements agreed with TPS modeled attenuation to within 2.1%. Planning target volume D95 changed less than 1% for 1 and 2 cm couch shifts in only the x-direction and less than 3% for all directions. Conclusions: Dosimetry of all plans tested was robust to couch shifts up to ±2 cm. In general, couch shifts resulted in clinically insignificant dosimetric deviations. It is conceivable that in certain cases with large systematic couch shifts and plans that are particularly sensitive to shifts, dosimetric changes might rise to a clinically significant level.

    The success of a long-duration space mission depends on various technical demands as well as on the psychological (cognitive, affective, and motivational) adaptation of crewmembers and the quality of interactions within the crew. We examined the ways crewmembers of a 520-day simulated spaceflight to Mars (held in the Institute for Biomedical Problems, in Moscow) experienced and regulated their moods and emotions. Results show that crewmembers experienced predominantly positive emotions throughout their 520-day isolation and the changes in mood of the crewmembers were asynchronous and balanced. The study suggests that during the simulation, crewmembers experienced and regulated their emotions differently than they usually do in their everyday life. In isolation, crewmembers preferred to suppress and neutralize their negative emotions and express overtly only emotions with positive valence. Although the affective processes were almost invariable throughout the simulation, two periods of time when the level of positive emotions declined were identified. Regarding the findings, the paper suggests that changes in positive affectivity could be a more valuable indicator of human experience in demanding but professional environments than changes in negative affectivity. Finally, the paper discusses the phenomenology of emotions during a real space mission.

    Despite the critical importance of successful recruitment and retention to study integrity, reporting of recruitment and retention strategies along with factors associated with successful recruitment and retention of participants in health-related interventions remain rare, especially for health and obesity prevention programs. Thus, the purpose of this article is to retrospectively examine the recruitment and retention marketing plan used in the online HomeStyles randomized controlled trial (RCT) and discuss outcomes associated with completion of the intervention. The HomeStyles RCT is an online intervention developed to motivate parents of young children to gain the skills and self-confidence needed to shape home environments and lifestyles to be protective against childhood obesity. Using the seven Ps of services marketing (i.e., people, place, product, physical evidence, price, promotion, and process), a comprehensive and systematic plan for recruitment and retention was implemented and outcomes assessed. A total of 489 parents with a young child aged 2 to attractiveness, interestingness, and usefulness. Despite all the retention efforts, the average monthly recruitment accrual rate of ~ 33 eligible enrolled participants at baseline (i.e., 489 participants/15-month recruitment period), declined to ~ 18, 11, 9, and 8 remaining recruited participants/month at midpoint, post, follow-up, and long-term follow-up surveys, respectively. In general, survey completers were significantly more likely to be female and perceived their child's health status to be better, and they were significantly less likely to be restrictive of their child's food intake. The findings of the present study highlight the need for far-reaching, concentrated, and varied recruitment strategies; sufficient time in the research plan for recruitment and retention activities; and creative, tireless, flexible, persistent project staff for health-related interventions.

    To assess whether there is a significant difference between the alignment of the individual femoral and tibial components (in the frontal, sagittal and horizontal planes) as calculated pre-operatively (digital plan) and the actually achieved alignment in vivo obtained with the use of patient-specific positioning guides (PSPGs) for TKA. It was hypothesised that there would be no difference between post-op implant position and pre-op digital plan. Twenty-six patients were included in this non-inferiority trial. Software permitted matching of the pre-operative MRI scan (and therefore calculated prosthesis position) to a pre-operative CT scan and then to a post-operative full-leg CT scan to determine deviations from pre-op planning in all three anatomical planes. For the femoral component, mean absolute deviations from planning were 1.8° (SD 1.3), 2.5° (SD 1.6) and 1.6° (SD 1.4) in the frontal, sagittal and transverse planes, respectively. For the tibial component, mean absolute deviations from planning were 1.7° (SD 1.2), 1.7° (SD 1.5) and 3.2° (SD 3.6) in the frontal, sagittal and transverse planes, respectively. Absolute mean deviation from planned mechanical axis was 1.9°. The a priori specified null hypothesis for equivalence testing: the difference from planning is >3 or plan in all planes, except for the tibial rotation in the transverse plane. Possible explanations for outliers are discussed and highlight the importance for adequate training surgeons before they start using PSPG in their day-by-day practise.

    2009-01-01

    After a presentation and a brief comment of levels of final energy consumptions per sector and per energy source in Aquitaine in 2008, a first report proposes a brief overview of a Negawatt-type scenario for the region, a brief presentation of the notion of positive-energy territories, and a brief evocation of the role of smart grids and of energy storage. It discusses the role of the building sector by commenting some initiatives, objectives of building renovation and of thermal insulation of individual dwellings, and the development of positive-energy building. Then, it describes opportunities of a rational and combined development of renewable energies in the region. It more deeply discusses these opportunities for biomass (wood, methanization, bio-fuels), solar photovoltaic, geothermal, wind, and marine energies. For each of them, stakes, objectives, assets and arrangements for research and development, and current activities are presented. The report then addresses the issue of education and training for professions related to a green growth, the issue of financial engineering for these developments, and the issue of social innovation and acceptance as they are addressed at the regional level. A second document presents the regional approach (initiatives, tools and arrangements, examples) for a positive-energy territory

    A cecal intubation rate (CIR) of >90% is a well-accepted quality indicator of colonoscopy and is consequently monitored within endoscopy units. Endoscopists' desire to meet this target may mean that incomplete colonoscopies are recorded as flexible sigmoidoscopies. The aim of this study was to examine whether the conversion of requested colonoscopies is a clinically significant phenomenon and whether this impacts upon the measurement of quality indicators. A retrospective review of all flexible sigmoidoscopies performed between 1 January 2015 and 31 December 2015 at Nottingham University Hospitals, Sheffield Teaching Hospitals, and Cambridge University Hospitals was performed. Where a colonoscopy was requested but a flexible sigmoidoscopy performed, the patient's records and endoscopy reports were reviewed to determine whether this conversion was decided before the start of the procedure and documented. During the 12-month period, 6,839 flexible sigmoidoscopies were performed by 125 endoscopists. The original requests of 149 sigmoidoscopies could not be retrieved and were therefore excluded from this analysis. Of the 6,690 sigmoidoscopy requests reviewed, 2.8% (n=190) procedures were originally requested as a colonoscopy. On review of patient records, 85 conversions were appropriate according to pre-defined criteria. However, 105 conversions were deemed inappropriate, occurring in patients who had a valid documented indication for colonoscopy and had undergone full bowel preparation. The most common reasons cited included poor bowel preparation (n=37), technically challenging procedure (n=24), at the endoscopist's discretion based on clinical factors (n=21), and obstructing patology (n=8). A clear reason for conversion was not apparent in 11 cases. During the study period, 21,271 colonoscopies were performed and so conversions represent 0.45% of the total requests. When inappropriate conversions were included in individuals' performance data, 15 endoscopists fell

    Managers require quantitative yet tractable tools that identify areas for restoration yielding effective benefits for targeted wildlife species and the ecosystems they inhabit. As a contemporary example of high national significance for conservation, the persistence of Greater Sage-grouse (Centrocercus urophasianus) in the Great Basin is compromised by strongly interacting stressors of conifer expansion, annual grass invasion, and more frequent wildfires occurring in sagebrush ecosystems. Associated restoration treatments to a sagebrush-dominated state are often costly and may yield relatively little ecological benefit to sage-grouse if implemented without estimating how Sage-grouse may respond to treatments, or do not consider underlying processes influencing sagebrush ecosystem resilience to disturbance and resistance to invasive species. Here, we describe example applications of a spatially explicit conservation planning tool (CPT) to inform prioritization of: (1) removal of conifers (i.e., pinyon-juniper); and (2) wildfire restoration aimed at improving habitat conditions for the Bi-State Distinct Population Segment of Sage-grouse along the California-Nevada state line. The CPT measures ecological benefits to sage-grouse for a given management action through a composite index comprised of resource selection functions and estimates of abundance and space use. For pinyon-juniper removal, we simulated changes in land-cover composition following the removal of sparse trees with intact understories, and ranked treatments on the basis of changes in ecological benefits per dollar-unit of cost. For wildfire restoration, we formulated a conditional model to simulate scenarios for land cover changes (e.g., sagebrush to annual grass) given estimated fire severity and underlying ecosystem processes influencing resilience to disturbance and resistance to invasion by annual grasses. For both applications, we compared CPT rankings to land cover changes along with sagebrush

    The impacts of climate change, defined as increasing atmospheric and oceanic carbon dioxide and associated increases in average global temperature and oceanic acidity, have been observed both globally and on regional scales, such as in the North-central California coast and ocean, a region that extends from Point Arena to Point Año Nuevo and includes the Pacific coastline of the San Francisco Bay Area. Because of the high economic and ecological value of the region’s marine environment, the Gulf of the Farallones National Marine Sanctuary (GFNMS) and other agencies and organizations have recognized the need to evaluate and plan for climate change impacts. Climate change indicators can be developed on global, regional, and site-specific spatial scales, and they provide information about the presence and potential impacts of climate change. While indicators exist for the nation and for the state of California as a whole, no system of ocean climate indicators exist that specifically consider the unique characteristics of the California coast and ocean region. To that end, GFNMS collaborated with over 50 regional, federal, and state natural resource managers, research scientists, and other partners to develop a set of 2 ocean climate indicators specific to this region. A smaller working group of 13 regional partners developed monitoring goals, objectives, strategies, and activities for the indicators and recommended selected species for biological indicators, resulting in the Ocean Climate Indicators Monitoring Inventory and Plan. The working group considered current knowledge of ongoing monitoring, feasibility of monitoring, costs, and logistics in selecting monitoring activities and selected species.

    The purpose of this study was to investigate the effect of multileaf collimator (MLC) leaf position, collimator rotation angle, and accelerator gantry rotation angle errors on intensity-modulated radiotherapy plans for nasopharyngeal carcinoma. To compare dosimetric differences between the simulating plans and the clinical plans with evaluation parameters, 6 patients with nasopharyngeal carcinoma were selected for simulation of systematic and random MLC leaf position errors, collimator rotation angle errors, and accelerator gantry rotation angle errors. There was a high sensitivity to dose distribution for systematic MLC leaf position errors in response to field size. When the systematic MLC position errors were 0.5, 1, and 2 mm, respectively, the maximum values of the mean dose deviation, observed in parotid glands, were 4.63%, 8.69%, and 18.32%, respectively. The dosimetric effect was comparatively small for systematic MLC shift errors. For random MLC errors up to 2 mm and collimator and gantry rotation angle errors up to 0.5°, the dosimetric effect was negligible. We suggest that quality control be regularly conducted for MLC leaves, so as to ensure that systematic MLC leaf position errors are within 0.5 mm. Because the dosimetric effect of 0.5° collimator and gantry rotation angle errors is negligible, it can be concluded that setting a proper threshold for allowed errors of collimator and gantry rotation angle may increase treatment efficacy and reduce treatment time.

    Until recently, PET was regarded as a luxurious way of performing myocardial perfusion scintigraphy, with excellent image quality and diagnostic capabilities that hardly justified the additional cost and procedural effort. Quantitative perfusion PET was considered a major improvement over standard qualitative imaging, because it allows the measurement of parameters not otherwise available, but for many years its use was confined to academic and research settings. In recent years, however, several factors have contributed to the renewal of interest in quantitative perfusion PET, which has become a much more readily accessible technique due to progress in hardware and the availability of dedicated and user-friendly platforms and programs. In spite of this evolution and of the growing evidence that quantitative perfusion PET can play a role in the clinical setting, there are not yet clear indications for its clinical use. Therefore, the Cardiovascular Committee of the European Association of Nuclear Medicine, starting from the experience of its members, decided to examine the current literature on quantitative perfusion PET to (1) evaluate the rationale for its clinical use, (2) identify the main methodological requirements, (3) identify the remaining technical difficulties, (4) define the most reliable interpretation criteria, and finally (5) tentatively delineate currently acceptable and possibly appropriate clinical indications. The present position paper must be considered as a starting point aiming to promote a wider use of quantitative perfusion PET and to encourage the conception and execution of the studies needed to definitely establish its role in clinical practice.

    The important roles of CCL2 and its receptor CCR2 had been reported in a series of inflammatory disorders. However, few studies investigated the potential role of CCL2/CCR2 axis in oral lichen planus (OLP). Therefore, this study aimed to detect the expression of CCL2 and CCR2 in OLP lesions and compare their changes before and after treatment. CCL2 and CCR2 expression was investigated using immunohistochemical staining and real-time RT-PCR in 32 patients with OLP and eight controls. Moreover, changes in their expression after treatment with triamcinolone acetonide were assessed in lesions from three patients. CCL2+ and CCR2+ cells were few in the controls and remarkably increased in the epithelial and subepithelial layers of lesions (n = 32, all P < 0.001). However, the densities of CCL2+ and CCR2+ cells were not significantly different between reticular (n = 12) and erythematous/erosive lesions (n = 20), although they significantly decreased after treatment (627.7 ± 108.2 vs. 258.3 ± 148.3, P = 0.017; 1034.7 ± 74.6 vs. 648 ± 77.6, P = 0.003, respectively). CCL2+/CCR2+ cell numbers were positively correlated with disease activity (correlation coefficient, 0.588; P < 0.001; correlation coefficient, 0.409; P = 0.02, respectively). The results of this study indicated that the CCL2-CCR2 axis was involved in the pathogenesis of OLP and was positively correlated with disease activity. © 2015 John Wiley & Sons A/S.

    Full Text Available To characterize the significance of correlated autoantibodies in systemic lupus erythematosus (SLE and its complication lupus nephritis (LN in a large cohort of patients.Clinical data were statistically analyzed in 1699 SLE patients with or without nephritis who were diagnosed and treated during 2002-2013 in the northeast region of China. Reactivity to a list of 16 autoantibodies was detected by the serum test Euroline ANA profile (IgG. Serum titers of the anti-nucleosome autoantibodies were measured by ELISA assays. Kidney biopsies were examined by pathologists. Immune complex deposition was identified by immunohistochemistry stain.Simultaneous positivity of anti-dsDNA, -nucleosome and -histone antibodies (3-pos was prevalent in SLE patients with LN compared to Non-renal SLE patients (41% vs 11%, p< 0.001. Significant correlations were found between any two of the above three anti-nucleosome antibodies in LN patients. In comparison to non-3-pos cohorts, 3-pos patients with LN had significantly higher serum levels of the three antibodies and more active disease; was associated with type IV disease; suffered from more severe renal damages; received more intensive treatment and had worse disease outcome. The serum levels of these three autoantibodies in 3-pos LN patients were significantly decreased when they underwent clinical recovery.Simultaneous reactivity to anti-dsDNA, -nucleosome and -histone antibodies by Euroline ANA profile (IgG may indicate severe nephropathy in patients with SLE.

    In 2002/03 the Queensland Government responded to high rates of alcohol-related harm in discrete Indigenous communities by implementing alcohol management plans (AMPs), designed to include supply and harm reduction and treatment measures. Tighter alcohol supply and carriage restrictions followed in 2008 following indications of reductions in violence and injury. Despite the plans being in place for over a decade, no comprehensive independent review has assessed to what level the designed aims were achieved and what effect the plans have had on Indigenous community residents and service providers. This study will describe the long-term impacts on important health, economic and social outcomes of Queensland's AMPs. The project has two main studies, 1) outcome evaluation using de-identified epidemiological data on injury, violence and other health and social indicators for across Queensland, including de-identified databases compiled from relevant routinely-available administrative data sets, and 2) a process evaluation to map the nature, timing and content of intervention components targeting alcohol. Process evaluation will also be used to assess the fidelity with which the designed intervention components have been implemented, their uptake and community responses to them and their perceived impacts on alcohol supply and consumption, injury, violence and community health. Interviews and focus groups with Indigenous residents and service providers will be used. The study will be conducted in all 24 of Queensland's Indigenous communities affected by alcohol management plans. This evaluation will report on the impacts of the original aims for AMPs, what impact they have had on Indigenous residents and service providers. A central outcome will be the establishment of relevant databases describing the parameters of the changes seen. This will permit comprehensive and rigorous surveillance systems to be put in place and provided to communities empowering them with the

    Purpose: In this study, we developed a system to calculate three dimensional (3D) dose that reflects dosimetric error caused by leaf miscalibration for head and neck and prostate volumetric modulated arc therapy (VMAT) without additional treatment planning system calculation on real time. Methods: An original system called clarkson dose calculation based dosimetric error calculation to calculate dosimetric error caused by leaf miscalibration was developed by MATLAB (Math Works, Natick, MA). Our program, first, calculates point doses at isocenter for baseline and modified VMAT plan, which generated by inducing MLC errors that enlarged aperture size of 1.0 mm with clarkson dose calculation. Second, error incuced 3D dose was generated with transforming TPS baseline 3D dose using calculated point doses. Results: Mean computing time was less than 5 seconds. For seven head and neck and prostate plans, between our method and TPS calculated error incuced 3D dose, the 3D gamma passing rates (0.5%/2 mm, global) are 97.6±0.6% and 98.0±0.4%. The dose percentage change with dose volume histogram parameter of mean dose on target volume were 0.1±0.5% and 0.4±0.3%, and with generalized equivalent uniform dose on target volume were −0.2±0.5% and 0.2±0.3%. Conclusion: The erroneous 3D dose calculated by our method is useful to check dosimetric error caused by leaf miscalibration before pre treatment patient QA dosimetry checks.

    To describe the role of magnetic resonance imaging (MRI) in establishing the indication for, planning, and following up uterine artery embolization (UAE) for treating symptomatic leiomyomas of the uterus on the basis of the current literature and our results. Retrospective analysis of the MRI findings obtained in 130 patients before and after UAE. Presentation of characteristic MRI features and their relevance in establishing the indication for, performing, and following up of UAE. Discussion of the results in conjunction with published data. The intermediate results of UAE reported in the literature show a successful improvement of leiomyoma-related symptoms in 82-94% of cases and an average reduction of leiomyoma size by 36-64%. The typical MRI appearance of degenerating leiomyomas is presented together with that of relevant differential diagnoses. MRI findings allow for establishing the indication for UAE by providing reliable information on the location, size, and number of uterine leiomyomas. Analysis of 60 patients of our study population showed solitary leiomyoma in 16% of cases, 2-10 leiomyomas in 47%, and over 10 in 37%. Subserosal, pedunculated leiomyomas cannot be treated by UAE; these were present in 5% of the patients. MR angiography is useful in assessing pelvic vascular anatomy before the intervention and identifies collateral vascular supply to the uterus. Contrast-enhanced imaging is suitable for monitoring successful devascularization following embolization and evaluating complications. (orig.) [de

    The Second Strategic Objective of the Global Vaccine Action Plan, "individuals and communities understand the value of vaccines and demand immunization as both their right and responsibility", differs from the other five in that it does not focus on supply-side aspects of immunization programs but rather on public demand for vaccines and immunization services. This commentary summarizes the work (literature review, consultations with experts, and with potential users) and findings of the UNICEF/World Health Organization Strategic Objective 2 informal Working Group on Vaccine Demand, which developed a definition for demand and indicators related to Strategic Objective 2. Demand for vaccines and vaccination is a complex concept that is not external to supply systems but rather encompasses the interaction between human behaviors and system structure and dynamics.

    Stereotactic Body Radiation Therapy (SBRT) requires a controlled immobilization and position monitoring of patient and target. The purpose of this work is to analyze the performance of the imaging system ExacTrac® (ETX) using infrared and fiducial markers. Materials and methods: In order to assure the accuracy of isocenter localization, a Quality Assurance procedure was applied using an infrared marker-based positioning system. Scans were acquired of an inhouse-agar gel and solid water phantom with infrared spheres. In the inner part of the phantom, three reference markers were delineated as reference and one pellet was place internally; which was assigned as the isocenter. The iPlan® RT Dose treatment planning system. Images were exported to the ETX console. Images were acquired with the ETX to check the correctness of the isocenter placement. Adjustments were made in 6D the reference markers were used to fuse the images. Couch shifts were registered. The procedure was repeated for verification purposes. Results: The data recorded of the verifications in translational and rotational movements showed averaged 3D spatial uncertainties of 0.31 ± 0.42 mm respectively 0.82° ± 0.46° in the phantom and the first correction of these uncertainties were of 1.51 ± 1.14 mm respectively and 1.37° ± 0.61°. Conclusions: This study shows a high accuracy and repeatability in positioning the selected isocenter. The ETX-system for verifying the treatment isocenter position has the ability to monitor the tracing position of interest, making it possible to be used for SBRT positioning within uncertainty ≤1mm.

    This paper details a practical method for the direct reconstruction of high dose rate 192Ir source dwell positions in ring applicators using gafchromic film in the treatment planning of brachytherapy cervix patients. It also details the uncertainties associated with such a process. Eight Nucletron interstitial ring applicators—Ø26 mm (×4), Ø30 mm (×3) and Ø34 mm (×1), and one 60 mm intrauterine tube were used in this study. RTQA2 and XRQA2 gafchromic films were irradiated at pre-programmed dwell positions with three successive 192Ir sources and used to derive the coordinates of the source dwell positions. The source was observed to deviate significantly from its expected position by up to 6.1 mm in all ring sizes. Significant inter applicator differences of up to 2.6 mm were observed between a subset of ring applicators. Also, the measured data were observed to differ significantly from commercially available source path models provided by Nucletron with differences of up to 3.7 mm across all ring applicator sizes. The total expanded uncertainty (k = 2) averaged over all measured dwell positions in the rings was observed to be 1.1 ± 0.1 mm (Ø26 mm and Ø30 mm rings) and 1.0 ± 0.3 mm (Ø34 mm ring) respectively, and when transferred to the treatment planning system, equated to maximum %dose changes of 1.9%, 13.2% and 1.5% at regions representative of the parametrium, lateral fornix and organs at risk respectively.

    The positive and negative predictive values of specific IgE to penicillins are not well established for penicillin hypersensitivity. One reason may be that serum IgE levels to penicillin diminish over time. The objective in this study was to investigate variations in serum half-life (T½) for specific IgE to penicillins (s-IgE) and to evaluate the outcome of penicillin challenges in patients with previous but not present specific IgE to penicillins. Two subgroups were investigated. All included patients had a history of penicillin allergy with reported symptoms such as urticaria/angioedema or unclassified cutaneous rash. T½ of specific IgE to penicillins was calculated based on sera from 29 patients with repeated measurements of s-IgE. Twenty-two patients with a previous positive s-IgE was followed and challenged with penicillin when IgE had become negative. The T½ for s-IgE varied between the 26 patients with decreasing s-IgE from 1.6 months to 76.4 months and 52% had a T½ of less than a year. The three patients with stable and increasing IgE-values showed T½ approaching infinity A total of 29 challenges with β-lactams were performed. Four different patterns were seen when evaluating the clinical reaction to challenge (positive/negative) and post-challenge boost of s-IgE (yes/no). Eight (36.4%) had negative challenge and negative post-challenge s-IgE, eight (36.4%) negative challenge, but positive post-challenge s-IgE levels. 3 (13.6%) had positive challenge and positive post-challenge s-IgE whereas 3 (13.6%) were challenge positive, but had negative post-challenge s-IgE. Specific IgE to penicillins declines over time stressing the importance of a close time relation between diagnostic work-up and clinical reaction. Reversal of previously positive s-IgE may still be associated with positive penicillin challenges and/or re-boostering of s-IgE to positivity.

    This study explored influences on intention to adhere to highly active antiretroviral therapy (HAART) among immigrant Latinos living with HIV/AIDS in the southeastern USA. Our community-based participatory research (CBPR) partnership completed individual in-depth interviews with 25 immigrant Latinos, based on the theory of planned behavior (TPB), to explore beliefs toward HAART adherence and HIV testing. Participants identified (a) seven outcomes of treatment adherence (e.g., "feeling good" and "controlling the virus"), (b) six groups of persons influencing adherence (e.g., family, partner/spouse), and (c) nine impediments to adherence (e.g., appointment scheduling, side effects of treatment). Fear of deportation, perceived costs of services, and barriers to communication emerged as impediments to both HAART adherence and HIV testing. The findings suggest the utility of TPB in identifying factors to enhance HAART adherence among immigrant Latinos. Future research should explore the extent to which these identified TPB components quantitatively influence adherence intention and immunological and virological outcomes. Culturally congruent interventions for immigrant Latinos may need to focus on facilitators of adherence, influential referent groups, and destigmatizing HIV/AIDS.

    2011-12-15

    On 17th December 2008 the German Federal Cabinet adopted the German Strategy for Adaptation to Climate Change (DAS: Deutsche Anpassungsstrategie) (BUNDESREGIERUNG 2008). The DAS has created the framework for adapting to the consequences of climate change in Germany. First and foremost, the DAS contributes its guidelines at Federal level, to provide guidance for agents at other levels. The Strategy lays the foundation for a medium-term process. In conjunction with the individual Federal States and other groups representing various sectors of society, the Strategy provides a step-by-step assessment of the risks of climate change. Furthermore, it states the potential requirements for action, and defines the appropriate goals and potential adaptation measures to be developed and implemented in the process. The Strategy is divided into 13 action fields and two cross-sectional fields (=14+15). (1) Human health (2) Building sector (3) Water regime, water management, coastal and marine protection (4) Soil (5) Biological diversity (6) Agriculture (7) Woodland and forestry (8) Fishery (9) Energy industry (conversion, transport and supply) (10) Financial services industry (11) Transport, transport infrastructure (12) Trade and industry (13) Tourism industry (14) Spatial, regional and physical development planning (15) Civil protection. In due course, the Federal Environment Agency (UBA) will design a comprehensive set of tools to support and implement the DAS. This will be made available for download from www.anpassung.net. An integral part of this will be the 'Tatenbank' (www.tatenbank.anpassung.net), the 'Klimalotse' (www.klimalotse.anpassung.net), FISKA (special information system 'Adaptation') and an Indicator System to aid adaptation. The latter is one of the key tasks identified for the DAS. As far as the Indicator System is concerned, it has been decided to prepare a Report on Indicators for the challenges facing Germany and the

    Purpose: Our aim was to report the control rate of radiographically positive retropharyngeal (RP) nodes with radiation therapy (RT) and to correlate posttreatment imaging with clinical outcome. Methods and Materials: Sixteen patients treated with definitive RT for head-and-neck cancer had radiographically positive RP nodes (size >1 cm in largest axial dimension, or presence of focal enhancement, lucency, or calcification), and both pre-RT and post-RT image sets available for review. An additional 21 patients with unconfirmed radiographically positive RP nodes had post-RT imaging, which consisted of computed tomography (CT) at a median of 4 weeks after completing RT. Patients with positive post-RT RP nodes underwent observation with serial imaging. Results: Of 16 patients with pre-RT and post-RT images available for review, 9 (56%) had a radiographic complete response, and of 21 patients with unconfirmed positive RP nodes with post-RT images available for review, 14 (67%) had a radiographic complete response. In all, 14 patients with incomplete response on post-RT imaging experienced control of their disease with no further therapy, and no RP node or neck failures were noted during a median follow-up of 2.8 years. Six patients with positive post-RT RP nodes had serial imaging available for review, and none demonstrated radiographic progression of disease. Conclusions: Radiographic response at 4 weeks may not accurately reflect long-term locoregional control, as RP nodes may continue to resolve over time. The highest index of suspicion should be reserved for patients with progressive changes in size, focal lucency, or focal enhancement on serial imaging after RT

    Full Text Available The objective of our study was to assess the association between position and swirling direction of the parietal whorl (PW and handedness. In 519 patients of a pediatric practice, PWs were located and the swirling direction determined. Of those patients, handedness could be specified in 217. The right-sided PW (n = 347; 70.8% and the clockwise (CW swirling type (n = 411; 83.9% of all participants were predominant in children with one PW. Non-right-handedness (NRH was found in 40 (18.4%. Medial position of the whorl per se increases the chance for NRH, indifferent of the swirling direction. In patients with counterclockwise (CCW swirling, the chance of NRH increased 3.5-fold for the right-sided, 5.4-fold for the left-sided, and 12.9-fold for the medial-positioned whorl. We conclude that NRH is associated with the position (medial! and the swirling direction (CCW! of the PW.

    A comparative assessment of alternative expansion plans for the Mexican electricity generating system was made by applying the Position Vector of Minimum Regret Analysis (PVMRA) as a decision analysis tool. Four expansion plans were ranked according to the following decision criteria: The cost which calculates the cumulated cost of electricity generation during the time period studied. The external cost which brings into play the costs associated with the impact on health and the environment. The risk which takes into account the economic impact associated with incremental fuel prices from the baseline scenario to the high scenario. The diversity which evaluates the generation park diversity in terms of the Shannon-Weaner Index. The foreign-capital fraction in investment using foreign inputs. The carbon-free fraction which evaluates electricity generation that contributes to climate change policies. The cost of severe-accidents which is the sum of full chain damage costs and external costs of severe accidents with at least 10 injured. Optimizations were made by internalizing the external cost into the objective function of the WASP-IV model, the cost of externalise of the operation and maintenance cost, and these expansions were compared with those that did not. Special attention was paid to studying the convenience of including nuclear power in the electricity generation mix. Furthermore, better electricity expansion plans, with lower internal and external costs, were also found when the optimization had included externalise

    Although family planning for human immune deficiency virus positive women has numerous advantages, evidences in different parts of the world showed the existence of persistent unmet need. There were few studies done in Ethiopia on level of unmet need for family planning among women in reproductive age on antiretroviral therapy (ART). This study was therefore done to determine the level of demand and unmet need for family planning among women on ART in South Gondar and North Wollo Zones, Amhara region. Institution based cross-sectional study design was used. Data was collected from June 15 to 25, 2013 in South Gondar and North Wollo Zones. Study participants were recruited from six health centers and two hospitals. The study participants were proportionally allocated to the health institutions. Multistage sampling technique was used to recruit study participants. Trained nurses interviewed the respondents using pretested structured Amharic questionnaire. Data was entered, cleaned and analyzed using Statistical Package for Social Science version 16. Ratios and proportions were computed to determine demand and unmet need for family planning. A total of 530 women in reproductive age on ART were interviewed in this study. Two hundred ninety-three women were married. Fourteen (2.6%) women were pregnant at the time of interview. Five of these pregnancies were not planned. In this study, 242 (45.7%) women reported that they were using contraceptives. Most women (74.4%) were using injectable (depo). Among those who were not using contraceptives, 84 (29.2%) reported that they will use in the future. Fifty-two (61.9%) of them said that they will use injectables (depo). In this study, the total demand for family planning among women on ART was 86.7%. From this, 62.1% and 24.6% was met and unmet need respectively. This study revealed that the level of demand and met need for modern contraceptives among reproductive age women on antiretroviral therapy in South Gondar and North

    Morbid obesity is strongly associated with nonalcoholic fatty liver disease (NAFLD), which is one of the most common causes of chronic liver disease worldwide. The present best treatment for NAFLD and nonalcoholic steatohepatitis (NASH) is weight reduction through lifestyle modification. Because of frustrating inefficiency of such a therapeutic approach, bariatric surgery is increasingly performed in adolescents as an alternative option for weight reduction. Standards of care and consensus for indications are, however, scarce. We explore the indications and limitations of bariatric surgery in children with severe obesity with and without NASH and aim to provide guidance for the exceptional indications for adolescents with extreme obesity with major comorbidity that may benefit from these controversial interventions. Present evidence suggests that bariatric surgery can decrease the grade of steatosis, hepatic inflammation, and fibrosis in NASH. Uncomplicated NAFLD is not an indication for bariatric surgery. Roux-en-Y gastric bypass is considered a safe and effective option for adolescents with extreme obesity, as long as an appropriate long-term follow-up is provided. Laparoscopic adjustable gastric banding has not been approved by the Food and Drug Administration for use in adolescents and therefore should be considered investigational. Finally, sleeve gastrectomy and other types of weight loss surgery that have grown increasingly common in adults, still need to be considered investigational. Temporary devices may be increasingly being used in pediatrics; however, future studies, including a long-term risk analysis of patients who undergo surgery, are much needed to clarify the exact indications for bariatric surgery in adolescents.

    Preclinical models of human mood disorders commonly focus on the study of negative affectivity, without comparably stressing the role of positive affects and their ability to promote resilient coping styles. We evaluated the role of background constitutional affect of rats by studying the separation and reunion responses of infants from low and high positive affect genetic lines (i.e., differentially selected for High and Low 50 kHz ultrasonic vocalisations (USVs). Infants from Low and High 50 kHz USV breeding lines were isolated from mothers and exposed to either social (familiar or unfamiliar bedding) or neutral (clean bedding) odour cues between two short isolation periods, and tested in homeothermic and hypothermic ambient temperatures. Negative affect was estimated by monitoring separation distress calls (35-45 kHz USVs). Low Line pups called at higher rates than High Line, and their rates were stable regardless of odour cue. In contrast, High Line pups increased vocalisations during the second compared with the first isolation periods and during exposure to both familiar and unfamiliar odour cues, but not to neutral odour. Furthermore, the greatest increase in USV emission was seen in the second isolation period following exposure to the unfamiliar odour. However, both lines showed comparable elevated distress USVs to the thermal stressor. High Line animals, selected for a positive affective phenotype (50 kHz USVs), exhibited reduced separation anxiety responses in infancy, making this a promising animal model for the role of constitutional affective states in emotional responsivity and potential resilience against emotional disorders.

    Numerous studies have shown that providing straw to pigs can reduce undesirable behaviours such as aggression, tail biting and stereotypy. The measurement of various neuromodulators can be helpful in assessing the development of positive behaviours and overall animal welfare. The oxytocin release is frequently linked to positive emotions and positive welfare. It has been suggested that oxytocin modulates the serotoninergic system. This study aims to investigate the potential effect of straw provision in pigs on peripheral levels of oxytocin and serotonin. In total, 18 mini-pigs were involved in an exploratory study conducted in two parallel groups, Enriched (n=10) and Control (n=8) groups. Pigs were divided by group and housed in pens of two individuals. Straw was provided continuously only in Enriched group and renewed each day for 2 weeks. Two blood samples were drawn from each animal 5 to 10 min before providing the straw, and 15 min after providing straw, during the 1st week, to analyse peripheral changes in oxytocin and serotonin before and after straw provision, and determine the existence of a putative short-term effect. The same procedure was carried out for Control group, without straw provision. Long-term effects of straw provision were also examined using blood samples drawn at the same hour from each animal in the 2nd and 3rd weeks. During this time, animals had the permanent possibility to explore the straw in Enriched group but not in Control group. At the end of each week, one animal-keeper completed two visual analogue scales for each mini-pig regarding the difficulty/ease to work with and handle it and its trust in humans. Results showed peripheral oxytocin increases in both groups after 2 weeks (P=0.02). Results did not demonstrate any effect of providing straw to allow exploratory behaviour on peripheral serotonin. Other results were not significant. This preliminary study explored the relationship between peripheral oxytocin and serotonin and

    Studies of alcohol use and sexual behavior in African populations have primarily been cross-sectional, used nonvalidated measures of alcohol use, or relied on self-reported sexual risk endpoints. Few have focused on human immunodeficiency virus (HIV)-positive women. Longitudinal data were collected from a cohort of HIV-positive Kenyan female sex workers. At enrollment and annual visits, participants were asked about past-year alcohol use using the Alcohol Use Disorders Identification Test (AUDIT). The primary endpoint was detection of prostate-specific antigen (PSA) in vaginal secretions at quarterly examinations. Associations between hazardous/harmful alcohol use (AUDIT score ≥7), PSA detection, and secondary measures of sexual risk were evaluated using generalized estimating equations with a log binomial regression model. A total of 405 women contributed 2750 vaginal samples over 606 person-years of follow-up. Hazardous/harmful alcohol use was reported at 16.6% of AUDIT assessments and was associated with higher risk of PSA detection (relative risk 1.50; 95% confidence interval, 1.11-2.01) relative to no alcohol use. This association was attenuated and no longer statistically significant, after adjusting for age, work venue, intimate partner violence, depression, and partnership status (adjusted relative risk, 1.13; 95% confidence interval, 0.82-1.56). In exploratory analyses, alcohol use was associated with self-report of unprotected sex and with sexually transmitted infection acquisition. Although hazardous/harmful alcohol use was not associated with detection of PSA in adjusted analysis, associations with secondary outcomes suggest that alcohol use is at least a marker of sexual risk behavior.

    This study was performed to determine the relationship between the stage of tooth eruption (both vertical and mesio-angular) and chronological age. Indirect digital panoramic radiographs were used to measure the distances from the dentinoenamel junction (DEJ) of the second molars to the occlusal plane of the second molar teeth and of the adjacent third molars in 264 Thai males and 437 Thai females using ImageJ software. The ratio of those distances was calculated by patient age, and the correlation coefficient of the ratio of the third molar length to the second molar length was calculated. The correlation between the height of the vertically erupted upper third molar teeth and age was at the intermediate level. The age range of ≥15 to age determined from the eruptional height and actual chronological age was statistically significant. The mean age of the female subjects, in which the position of the right upper third molar teeth was at or above the DEJ of the adjacent second molar but below one half of its coronal height was 19.9±2.6 years. That for the left side was 20.2±2.7 years. The mean ages of the male subjects were 20.1±3.3 years and 19.8±2.7 years for the right and left sides, respectively. It might be possible to predict chronological age from the eruption height of the wisdom teeth.

    The purpose of our study is to compare oncologic and functional outcomes of p16-positive oropharyngeal squamous cell carcinoma (OPSCC) patients, in the presence and absence of planned radiation to the primary bed following transoral surgery (TOS), stratified by T-classification. Retrospective cohort study of 261, T1-T4, consecutively TOS-treated OPSCC patients. At a median follow-up of 61months, local recurrence (LR) occurred in 6 (2.3%)patients (3 each in T1-T2 and T3-T4 groups), of which 5 had tumors in the tongue base and one in the tonsil. Of patients not receiving planned primary bed radiation, LR occurred in 3% of T1-T2s versus 17% of T3-T4s. In patients with T1-T2 tumors, Absolute Risk Reduction of LR with primary bed radiation was 3.26% (95% CI: -0.37%, 7%); Number Needed to Treat to prevent one LR was 31 (95% CI: 14.5, 271). Absolute Risk Increase for gastrostomy-tube with primary bed radiation was 34.4% (95% CI: 24%, 45%); Number Needed to Harm was 3 (95% CI: 2.2, 4.2), i.e., for every three patients with T1-T2 tumors receiving primary bed radiation, one had a gastrostomy-tube. Elimination of primary bed radiation in margin-negative resected, T1-T2 p16-positive OPSCC was not associated with significant compromise of local control, and correlated with superior swallowing preservation, assessed using gastrostomy rate as a surrogate. Lack of primary bed radiation in T3-T4 tumors associated with significantly increased LR rates. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Purpose: To develop adaptive planning with feedback for MRI-guided focal HDR prostate brachytherapy with a single divergent needle robotic implant device. After each needle insertion, the dwell positions for that needle are calculated and the positioning of remaining needles and dosimetry are both updated based on MR imaging. Methods: Errors in needle positioning may occur due to inaccurate needle insertion (caused by e.g. the needle’s bending) and unpredictable changes in patient anatomy. Consequently, the dose plan quality might dramatically decrease compared to the preplan. In this study, a procedure was developed to re-optimize, after each needle insertion, the remaining needle angulations, source positions and dwell times in order to obtain an optimal coverage (D95% PTV>19 Gy) without exceeding the constraints of the organs at risk (OAR) (D10% urethra<21 Gy, D1cc bladder<12 Gy and D1cc rectum<12 Gy). Complete HDR procedures with 6 needle insertions were simulated for a patient MR-image set with PTV, prostate, urethra, bladder and rectum delineated. Random angulation errors, modeled by a Gaussian distribution (standard deviation of 3 mm at the needle’s tip), were generated for each needle insertion. We compared the final dose parameters for the situations (I) without re-optimization and (II) with the automatic feedback. Results: The computation time of replanning was below 100 seconds on a current desk computer. For the patient tested, a clinically acceptable dose plan was achieved while applying the automatic feedback (median(range) in Gy, D95% PTV: 19.9(19.3–20.3), D10% urethra: 13.4(11.9–18.0), D1cc rectum: 11.0(10.7–11.6), D1cc bladder: 4.9(3.6–6.8)). This was not the case without re-optimization (median(range) in Gy, D95% PTV: 19.4(14.9–21.3), D10% urethra: 12.6(11.0–15.7), D1cc rectum: 10.9(8.9–14.1), D1cc bladder: 4.8(4.4–5.2)). Conclusion: An automatic guidance strategy for HDR prostate brachytherapy was developed to compensate

    Patients with human papillomavirus DNA positive (HPV DNA +) oropharyngeal squamous cell carcinoma (OSCC) have better clinical outcome than those with HPV DNA negative (HPV DNA −) OSCC upon intensive oncological treatment. All HPV DNA + OSCC patients may not require intensive treatment, however, but before potentially deintensifying treatment, additional predictive markers are needed. Here, we examined HPV, p16 INK4a , and CD44 in OSCC in correlation to clinical outcome. Pretreatment tumors from 290 OSCC patients, the majority not receiving chemotherapy, were analyzed for HPV DNA by Luminex and for p16 INK4a and CD44 by immunohistochemistry. 225/290 (78%) tumors were HPV DNA + and 211/290 (73%) overexpressed p16 INK4a , which correlated to presence of HPV (P < 0.0001). Presence of HPV DNA, absent/weak CD44 intensity staining correlated to favorable 3-year disease-free survival (DFS) and overall survival (OS) by univariate and multivariate analysis, and likewise for p16 INK4a by univariate analysis. Upon stratification for HPV, HPV DNA + OSCC with absent/weak CD44 intensity presented the significantly best 3-year DFS and OS, with >95% 3-year DFS and OS. Furthermore, in HPV DNA + OSCC, p16 INK4a + overexpression correlated to a favorable 3-year OS. In conclusion, patients with HPV DNA + and absent/weak CD44 intensity OSCC presented the best survival and this marker combination could possibly be used for selecting patients for tailored deintensified treatment in prospective clinical trials. Absence of/weak CD44 or presence of human papillomavirus (HPV) DNA was shown as a favorable prognostic factors in tonsillar and tongue base cancer. Moreover, patients with the combination of absence of/weak CD44 and presence of HPV DNA presented a very favorable outcome. Therefore, we suggest that this marker combination could potentially be used to single out patients with a high survival that could benefit from a de-escalated oncological treatment

    Objective To assess the use of Global Positioning System receiver (GPS) derived performance measures for differentiating between: 1) different outdoor activities in healthy dogs; 2) healthy dogs and those with osteoarthritis; 3) osteoarthritic dogs before and after treatment with non-steroidal anti-inflammatory analgesia. Design Prospective study. Animals Ten healthy dogs and seven dogs with osteoarthritis of the elbow joint (OA dogs). Procedure Healthy dogs were walked on a standard route on-lead, off-lead and subjected to playing activity (chasing a ball) whilst wearing a GPS collar. Each dog was walked for five consecutive days. Dogs with OA were subjected to a single off-lead walk whilst wearing a GPS collar, and then administered oral Carprofen analgesia daily for two weeks. OA dogs were then subjected to the same walk, again wearing a GPS collar. Results GPS derived measures of physical performance could differentiate between on-lead activity, off-lead activity and playing activity in healthy dogs, and between healthy dogs and OA dogs. Variation in the performance measures analysed was greater between individual dogs than for individual dogs on different days. Performance measures could differentiate healthy dogs from OA dogs. OA Dogs treated with Carprofen analgesia showed improvements in their physical performance, which returned to values indistinguishable from those of healthy dogs on nearly all the measures assessed. Conclusions and Clinical Relevance GPS derived measures of physical performance in dogs are objective, easy to quantify, and can be used to gauge the effects of disease and success of clinical treatments. Specific stimuli can be used to modulate physical performance beyond the self-governed boundaries that dogs will naturally express when allowed to exercise freely without stimulation. PMID:25692761

Comparison of CP and CN heroin addicts in terms of rheumatoid factor (RF and circulating immune complexes (CIC; 3. Assessment of clinical manifestations in CP heroin addicts. Methods. This is a comparative study of cases (outpatients treated at the University Clinic of Toxicology in Skopje over 3.5 years, from January 2009 to June 2012. In this study 140 heroin addicts without HbsAg were examined, seronegative for HCV and HIV infections. They were divided into 2 groups: 70 CP and 70 CN heroin addicts. A previously designed self-administered questionnaire was used as a data source on participants. All heroin addicts underwent the following analyses: urea and creatinine in serum; creatinine in urine; proteinuria; 24-hour proteinuria; IgM, IgG, IgA, C3, C4 ; RF; CIC; creatinine clearance; ECG; toxicological analyses for opioids in a urine sample; cryoglobulins. In addition to these 2 groups, IgG, IgA, IgM, C3 and C4 were also examined in 70 healthy subjects (CG. Results. The study showed that there was no statistically significant difference between CP, CN heroin addicts and CG regarding the concentration of IgA, IgG, IgM, C3 and C4, and between CP and CN regarding the concentration of CIC. There was significant difference between CP and CN regarding the concentration of RF. The following conditions were significantly more frequently manifested in CP than in CN heroin addicts: arthralgia, Raynaud’s phenomenon, respiratory difficulties, neurological disorders, manifested skin changes, hematuria, 24-hour proteinuria levels, and decreased renal clearance. Conclusion. There were no

    Past research supports individual planning as an effective intervention strategy to increase physical activity in individuals. A similar strategy, dyadic planning, adds a planning partner who supports an individual's planning processes. Whether the two planning formats differ in terms of participants' entered plan content and whether and how different content characteristics are linked to plan enactment remains unknown. By investigating the content of generated plans, this study aimed at distinguishing plan characteristics of the two planning formats and examining their role as predictors of later plan enactment. Secondary analyses of a three-arm RCT with German couples (data collection between 2013 and 2015). Couples were assigned to an individual (IPC, n = 114) or dyadic planning condition (DPC, n = 111) and formulated up to 5 physical activity plans for a target person. Couples assigned to a control condition were not included as they did not generate plans. The following characteristics were distinguished and coded for each plan: number of planned opportunities, presence of a planned routine, planned cue- or activity-related specificity, activity-related intensity, and chronological plan rank. One week before (T0) and two weeks following (T2) the intervention (T1), increase vs. no increase of the planned activity was coded as a dichotomous plan enactment variable. Multilevel logistic regressions were fit. Plan enactment was higher in dyadic than in individual planners. Findings indicated that routines (e.g., after work) were positively related to plan enactment, whereas a high specificity of when-cues (e.g., Friday at 6.30 p.m.) showed a negative relationship. None of the examined plan characteristics could explain differences in enactment between IPC and DPC. Linking health behaviours to other behavioural routines seems beneficial for subsequent plan enactment. Dyadic planning was linked with higher enactment rates than individual planning. However, as

    Full Text Available Abstract Background At present there is no consensus on irradiation treatment volumes for intermediate to high-risk primary cancers or recurrent disease. Conventional imaging modalities, such as CT, MRI and transrectal ultrasound, are considered suboptimal for treatment decisions. Choline-PET/CT might be considered as the imaging modality in radiooncology to select and delineate clinical target volumes extending the prostate gland or prostate fossa. In conjunction with intensity modulated radiotherapy (IMRT and imaged guided radiotherapy (IGRT, it might offer the opportunity of dose escalation to selected sites while avoiding unnecessary irradiation of healthy tissues. Methods Twenty-six patients with primary (n = 7 or recurrent (n = 19 prostate cancer received Choline-PET/CT planned 3D conformal or intensity modulated radiotherapy. The median age of the patients was 65 yrs (range 45 to 78 yrs. PET/CT-scans with F18-fluoroethylcholine (FEC were performed on a combined PET/CT-scanner equipped for radiation therapy planning. The majority of patients had intermediate to high risk prostate cancer. All patients received 3D conformal or intensity modulated and imaged guided radiotherapy with megavoltage cone beam CT. The median dose to primary tumours was 75.6 Gy and to FEC-positive recurrent lymph nodal sites 66,6 Gy. The median follow-up time was 28.8 months. Results The mean SUVmax in primary cancer was 5,97 in the prostate gland and 3,2 in pelvic lymph nodes. Patients with recurrent cancer had a mean SUVmax of 4,38. Two patients had negative PET/CT scans. At 28 months the overall survival rate is 94%. Biochemical relapse free survival is 83% for primary cancer and 49% for recurrent tumours. Distant disease free survival is 100% and 75% for primary and recurrent cancer, respectively. Acute normal tissue toxicity was mild in 85% and moderate (grade 2 in 15%. No or mild late side effects were observed in the majority of patients (84%. One patient had

    FDG-PET and PET / CT is increasingly used for radiotherapy (RT) planning in non-small-cell lung carcinoma (NSCLC). The planning process is often based on separately-acquired FDG-PET / CT and planning CT. We compared intraindividual differences between PET acquired in diagnostic and radiotherapy treatment position coregistered with planning CTs acquired using different breathing protocols. Sixteen patients with NSCLC underwent two PET acquisitions (diagnostic position-D-PET, radiotherapy position-RT-PET) and three planning-CT acquisitions (expiration-EXP, inspiration-INS, mid-breathhold-MID) on the same day. All scans were rigidly coregistered resulting in six fused datasets: D-INS, D-EXP, D-MID, RT-INS, RT-EXP and RT-MID. Fusion accuracy was assessed by three readers at eight anatomical landmarks: lung apices, aortic arch, heart, spine, sternum, carina, diaphragm and tumor using an alignment score ranging from 1 (no alignment) to 5 (exact alignment). RT-PET showed better alignment with any CT than D-PET (p < 0.001). With regard to breathing, RT-MID showed the best mean alignment score (3.7 {+-} 1.0) followed by RT-EXP (3.5 {+-} 0.9) and RT-INS (3.0 {+-} 0.8), all differences being significant (p < 0.001). Comparing the alignment scores with regard to anatomical landmarks, the largest deviations were found at diaphragm, heart and apices. Overall, there was a fair agreement (? = 0.48; p < 0.001) among the three readers. Significantly better fusion of PET and planning-CT can be reached with PET acquired in RT-position. The best intraindividual fusion results are obtained with the planning-CT performed during mid-breathhold. Our data justify the acquisition of a separate planning-PET in RT-treatment position if only a diagnostic PET-scan is available. (orig.)

    Purpose: Reduction of irradiated small bowel volume, using a conformal three-dimensional treatment planning technique in postoperative radiotherapy of cervical cancer patients. Patients and Methods: Large gynecological treatment fields including the para-aortic nodes were analyzed in 15 patients. A conventional treatment plan with anterior and posterior (AP-PA) parallel opposed fields and a 3D 4-field conformal radiotherapy plan with a central blocking of small bowel were compared for each patient. Dose-volume histograms and dose parameters were established. Because of the tolerance constraints of the small bowel, the cumulative dose applied to the target was 48.6 Gy. Results: The mean Tumor Control Probability (TCP) values for both the conventional and the conformal technique were 0.60 and 0.61, respectively, with ranges of 0.56 to 0.67 and 0.57 to 0.66, respectively. The mean volume receiving 95% or more of the prescribed dose (V95) of the small bowel was 47.6% (32.5 to 66.3%) in the AP-PA technique and 14.9% (7.0 to 22.5%) in the conformal technique (p<0.001), indicating a significant reduction in irradiated volume of small bowel in the higher dose range. The mean Normal Tissue Complication Probability (NTCP) decreased from 0.11 to 0.03 with the conformal plan. In patients who received a pedicled omentoplasty during surgery, the mean V95 for small bowel could be reduced to 8.5% (7.0 to 9.9%). The mean median dose to the kidneys was only slightly elevated in the conformal treatment. Especially the mean dose to the right kidney in conventional vs conformal treatment was 3.3 vs 7.9 Gy. The mean near-minimum dose (D95) to the rectosigmoid decreased from 48.4 to 30.1 Gy in the conformal plan compared to the conventional plan. Conclusion: The small bowel dose can be significantly reduced with 3D treatment planning, particularly if a predicled omentoplasty is performed. This allows dose escalation to the tumor region without unacceptable toxicity for the small bowel

    Planning policy makers are requesting clearer guidance on the key design features required to build neighbourhoods that promote active living. Using a backwards stepwise elimination procedure (logistic regression with generalised estimating equations adjusting for demographic characteristics, self-selection factors, stage of construction and scale of development) this study identified specific design features (n=16) from an operational planning policy ("Liveable Neighbourhoods") that showed the strongest associations with walking behaviours (measured using the Neighbourhood Physical Activity Questionnaire). The interacting effects of design features on walking behaviours were also investigated. The urban design features identified were grouped into the "building blocks of a Liveable Neighbourhood", reflecting the scale, importance and sequencing of the design and implementation phases required to create walkable, pedestrian friendly developments.

    The indication of adjuvant chemotherapy for patients with highly proliferative estrogen receptor-positive breast cancer is controversial. We analyzed the predictive value of Ki67 for the efficacy of adjuvant chemotherapy in patients with estrogen receptor-positive, node-positive breast cancer. We identified 1241 patients with Luminal B early stage breast cancer with 1-3 axillary positive nodes who underwent surgery between 1995 and 2005 at the European Institute of Oncology and received adjuvant hormonotherapy and/or chemotherapy. Differences in the distribution of characteristics according to treatment were evaluated by the Chi-square test. To evaluate the effect of adding chemotherapy to hormonotherapy, the propensity score method was used to match patients' characteristics minimizing bias related to the non-random assignment of treatment. The probability of receiving chemotherapy was significantly associated with age, tumor grade, degree of hormone responsiveness, tumor size and peripheral vascular invasion. The propensity score distribution was statistically different between the two treatment groups (p chemotherapy group (log-rank test p-value 0.663). The 5-year DFS percentages were 84.6% (95% CI, 81.0-87.6%) in the hormonotherapy group and 84.2% (95% CI, 81.3-86.7%) in the hormonotherapy/chemotherapy group (log-rank test p-value 0.388). However, when analyzing the 5-year DFS by Ki-67 distribution, Subpopulation Treatment Effect Pattern Plot (STEPP) analysis showed a beneficial effect of chemotherapy in patients with highly proliferative tumor (Ki-67 ≥ 32%). The interaction between Ki-67 and treatment was statistically significant (p = 0.027). Ki67 expression identifies a subset of patients with Luminal B and node-positive breast cancer who could benefit from addition of adjuvant chemotherapy to hormonotherapy. Dichotomy was observed for Ki67 at 32% level. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Marine Protected Areas (MPAs) are widely used as tools to maintain biodiversity, protect habitats and ensure that development is sustainable. If MPAs are to maintain their role into the future it is important for managers to understand how conditions at these sites may change as a result of climate change and other drivers, and this understanding needs to extend beyond temperature to a range of key ecosystem indicators. This case study demonstrates how spatially-aggregated model results for multiple variables can provide useful projections for MPA planners and managers. Conditions in European MPAs have been projected for the 2040s using unmitigated and globally managed scenarios of climate change and river management, and hence high and low emissions of greenhouse gases and riverborne nutrients. The results highlight the vulnerability of potential refuge sites in the north-west Mediterranean and the need for careful monitoring at MPAs to the north and west of the British Isles, which may be affected by changes in Atlantic circulation patterns. The projections also support the need for more MPAs in the eastern Mediterranean and Adriatic Sea, and can inform the selection of sites.

  12. Climate change policy position

    International Nuclear Information System (INIS)

    2002-11-01

    The Canadian Association of Petroleum Producers (CAPP) is a firm believer in the need to take action to mitigate the risks associated with climate change, and that clear government policy is called for. The principles of sustainable development must guide this policy development effort. The initiatives required to address greenhouse gas emissions over both the short and long term must be carefully considered, and it is up to industries to ensure their production efficiency and emission intensity. Promoting improved performance of industries in Canada and developing technology that can be deployed internationally for larger global effects represents Canada's best contribution to progress on greenhouse gas emissions. The increase in energy demand along with increases in population and economic growth have contributed to an increase in greenhouse gas emissions despite improved energy efficiency in industry. Significant damage to the economy will result if Canada is to meet its commitment under the Kyoto Protocol, forcing the country to buy large quantities of foreign credits instead of using those funds for increased research and development. CAPP indicated that an effective plan must be: balanced, equitable, responsible, competitive, focused on technology and innovation, and based on agreements on sectoral plans. Each of these principles were discussed, followed by the fundamentals of approach for upstream oil and gas. The framework for climate change policy was described as well as the elements of a sector plan. CAPP wants to work with all levels of government on an appropriate plan for Canada, that considers our unique circumstances. Canada can play a significant role on the international stage by properly implementing the policy position proposed by the CAPP without unnecessary risks to the economy. refs

    Chen Wenjing; Gemmel, Alexander; Rietzel, Eike

    2013-01-01

    We propose a plan adaptation method for fast treatment plan generation in scanned ion beam therapy. Analysis of optimized treatment plans with carbon ions indicates that the particle number modulation of consecutive rasterspots in depth shows little variation throughout target volumes with convex shape. Thus, we extract a depth-modulation curve (DMC) from existing reference plans and adapt it for creation of new plans in similar treatment situations. The proposed method is tested with seven CT serials of prostate patients and three digital phantom datasets generated with the MATLAB code. Plans are generated with a treatment planning software developed by GSI using single-field uniform dose optimization for all the CT datasets to serve as reference plans and ‘gold standard’. The adapted plans are generated based on the DMC derived from the reference plans of the same patient (intra-patient), different patient (inter-patient) and phantoms (phantom-patient). They are compared with the reference plans and a re-positioning strategy. Generally, in 1 min on a standard PC, either a physical plan or a biological plan can be generated with the adaptive method provided that the new target contour is available. In all the cases, the V95 values of the adapted plans can achieve 97% for either physical or biological plans. V107 is always 0 indicating no overdosage, and target dose homogeneity is above 0.98 in all cases. The dose received by the organs at risk is comparable to the optimized plans. The plan adaptation method has the potential for on-line adaptation to deal with inter-fractional motion, as well as fast off-line treatment planning, with either the prescribed physical dose or the RBE-weighted dose.

    The objectives of the study reported here were to propose a model that can be used in the analysis of possible future ORV-related events and to outline a set of performance indicators that can be used by the inspectorate to assess a utility's level of readiness if an ORV-event should take place. Together the two objectives serve to improve the inspectorate's ability to ensure that the utilities maintain an adequate capability to respond. The background for the current study is the nine ORV events that occurred in Sweden between 1995- 1998, as well as the findings of a previous study of safety during outage and restart of nuclear power plants project. This study found that the three levels or types of tests that occur in ORV were used according to need rather than according to a predefined arrangement or procedure, and that tasks were adapted relative to the different types of embedding and the degree of correspondence between nominal and actual ORV. The organisation's coping with the complexity of ORV was discussed by the relation between expectations and surprises, how planning was used as control, attention to details, and the practices of shift changes. It is a truism that accidents are analysed and interpreted relative to a commonly accepted understanding of their nature. This understanding is, however, relative rather than absolute, and has changed significantly during the last decade. In the 1990s, accidents were analysed step by step, and explanations and recommendations therefore emphasised specific rather than generic solutions. The present study illustrates this by going through the responses to the nine ORV events. Following that, the nine events are analysed anew using a contemporary understanding of accidents (a systemic model), which emphasises that incidents more often arise from context induced performance variability than from failures of people. The alternative interpretation provided by a systemic model is illustrated by a detailed

    To describe the role of magnetic resonance imaging (MRI) in establishing the indication for, planning, and following up uterine artery embolization (UAE) for treating symptomatic leiomyomas of the uterus on the basis of the current literature and our results. Retrospective analysis of the MRI findings obtained in 130 patients before and after UAE. Presentation of characteristic MRI features and their relevance in establishing the indication for, performing, and following up of UAE. Discussion of the results in conjunction with published data. The intermediate results of UAE reported in the literature show a successful improvement of leiomyoma-related symptoms in 82-94% of cases and an average reduction of leiomyoma size by 36-64%. The typical MRI appearance of degenerating leiomyomas is presented together with that of relevant differential diagnoses. MRI findings allow for establishing the indication for UAE by providing reliable information on the location, size, and number of uterine leiomyomas. Analysis of 60 patients of our study population showed solitary leiomyoma in 16% of cases, 2-10 leiomyomas in 47%, and over 10 in 37%. Subserosal, pedunculated leiomyomas cannot be treated by UAE; these were present in 5% of the patients. MR angiography is useful in assessing pelvic vascular anatomy before the intervention and identifies collateral vascular supply to the uterus. Contrast-enhanced imaging is suitable for monitoring successful devascularization following embolization and evaluating complications. (orig.)

    We evaluated the prognostic significance and universal validity of the total number of evaluated lymph nodes (ELN), number of positive lymph nodes (PLN), lymph node ratio (LNR), and log odds of positive lymph nodes (LODDS) in a relatively large and homogenous cohort of surgically treated pancreatic ductal adenocarcinoma (PDAC) patients. Prospectively accrued data were retrospectively analyzed for 282 PDAC patients who had pancreaticoduodenectomy (PD) at our institution. Long-term survival was analyzed according to the ELN, PLN, LNR, and LODDS. Of these patients, 168 patients (59.5 %) had LN metastasis (N1). Mean ELN and PLN were 13.5 and 1.6, respectively. LN positivity correlated with a greater number of evaluated lymph nodes; positive lymph nodes were identified in 61.4 % of the patients with ELN ≥ 13 compared with 44.9 % of the patients with ELN < 13 (p = 0.014). Median overall survival (OS) and 5-year OS rate were higher in N0 than in N1 patients, 22.4 vs. 18.7 months and 35 vs. 11 %, respectively (p = 0.008). Mean LNR was 0.12; 91 patients (54.1 %) had LNR < 0.3. Among the N1 patients, median OS was comparable in those with LNR ≥ 0.3 vs. LNR < 0.3 (16.7 vs. 14.1 months, p = 0.950). Neither LODDS nor various ELN and PLN cutoff values provided more discriminative information within the group of N1 patients. Our data confirms that lymph node positivity strongly reflects PDAC biology and thus patient outcome. While a higher number of evaluated lymph nodes may provide a more accurate nodal staging, it does not have any prognostic value among N1 patients. Similarly, PLN, LNR, and LODDS had limited prognostic relevance.

It has been rarely identified in the head and neck region. Herein, we describe a DSRCT in the maxilla of a young man, who was initially diagnosed with a primitive neuroectodermal tumor (PNET, based on histopathological appearance of a round cell tumor, with MIC2 and -FLI-1 positivity, on immunohistochemistry (IHC. Diagnosis of a DSRCT was confirmed on molecular analysis with positive -RT-PCR and sequencing results for EWS-WT1 transcript and negativity for EWS-FL1. The case is presented to highlight the value of molecular diagnosis in round cell sarcomas at uncommon sites, especially when similar IHC markers can be expressed in a PNET and a DSRCT. An exact diagnosis of a round cell sarcoma has a therapeutic relevance.

    Does planning for a particular workday help employees perform better than on other days they fail to plan? We investigate this question by identifying 2 distinct types of daily work planning to explain why and when planning improves employees' daily performance. The first type is time management planning (TMP)-creating task lists, prioritizing tasks, and determining how and when to perform them. We propose that TMP enhances employees' performance by increasing their work engagement, but that these positive effects are weakened when employees face many interruptions in their day. The second type is contingent planning (CP) in which employees anticipate possible interruptions in their work and plan for them. We propose that CP helps employees stay engaged and perform well despite frequent interruptions. We investigate these hypotheses using a 2-week experience-sampling study. Our findings indicate that TMP's positive effects are conditioned upon the amount of interruptions, but CP has positive effects that are not influenced by the level of interruptions. Through this study, we help inform workers of the different planning methods they can use to increase their daily motivation and performance in dynamic work environments.

  13. Feasibility of identification of gamma knife planning strategies by identification of pareto optimal gamma knife plans.

    Giller, C A

    2011-12-01

    The use of conformity indices to optimize Gamma Knife planning is common, but does not address important tradeoffs between dose to tumor and normal tissue. Pareto analysis has been used for this purpose in other applications, but not for Gamma Knife (GK) planning. The goal of this work is to use computer models to show that Pareto analysis may be feasible for GK planning to identify dosimetric tradeoffs. We define a GK plan A to be Pareto dominant to B if the prescription isodose volume of A covers more tumor but not more normal tissue than B, or if A covers less normal tissue but not less tumor than B. A plan is Pareto optimal if it is not dominated by any other plan. Two different Pareto optimal plans represent different tradeoffs between dose to tumor and normal tissue, because neither plan dominates the other. 'GK simulator' software calculated dose distributions for GK plans, and was called repetitively by a genetic algorithm to calculate Pareto dominant plans. Three irregular tumor shapes were tested in 17 trials using various combinations of shots. The mean number of Pareto dominant plans/trial was 59 ± 17 (sd). Different planning strategies were identified by large differences in shot positions, and 70 of the 153 coordinate plots (46%) showed differences of 5mm or more. The Pareto dominant plans dominated other nearby plans. Pareto dominant plans represent different dosimetric tradeoffs and can be systematically calculated using genetic algorithms. Automatic identification of non-intuitive planning strategies may be feasible with these methods.

    It has been suggested that it is very important to position patients reproducibly at different stages of radiotherapy treatment planning and treatment, or similar procedures. Devices have been described for positioning a patient's upper and lower thorax. This invention provides reproducible positioning for a female patient's breasts, for example in planning treatment of and treating breast tumours. The patient is placed prone, using for example an upper thorax device. A support device is placed central to and beneath her breasts to partially displace them outwards. The device may be triangular in section with one apex contacting the chest wall at the sternum. Restraining straps may be provided to hold the breasts against the support device. Means may be provided to take a healthy breast from the path of radiation through the tumour. (author)

    Within the realm of evaluating self-monitoring plans, developed based on the Hazard Analysis and Critical Control Points (HACCP) method and adopted by food companies, little research has been done concerning the quality of the plans. The Servizio di Igiene degli Alimenti e della Nutrizione (Food and Nutrition Health Service) of the Local Health Authority of Foggia, Italy, has conducted research with the aim to adopt a system of indexes and indicators for the qualitative evaluation of HACCP plans. The critical areas considered were the following: simplicity, specificity, feasibility and adherence. During the period from January 2004 to June 2005, the evaluation grid was used in examining 250 HACCP self-monitoring plans of food companies. For the analysis of the determining factor four groups were considered, with reference to HACCP self-monitoring plans designed: group 1 - with the aid of a qualified team; group 2 - with the aid of an unqualified team; group 3 - with the aid of an unqualified expert; group 4 - without the aid of an expert. The mean values of the measures elaborated decrease towards insufficiency moving from group 1 to group 4. In particular, collaboration by teams of unqualified experts brought about drafting unacceptable HACCP plans on the levels of specificity and adherence, with respect to the HACCP method. The method proposed of the analysis of the indexes and indicators beginning with an evaluation sheet can also help the individual company to better adjust contribution by internal or external professionals to the company.

    To assess age differences in the costs of language planning and production. A controlled sentence production task was combined with digital pursuit rotor tracking. Participants were asked to track a moving target while formulating a sentence using specified nouns and verbs and to continue to track the moving target while producing their response. The length of the critical noun phrase (NP) as well as the type of verb provided were manipulated. The analysis indicated that sentence planning was more costly than sentence production, and sentence planning costs increased when participants had to incorporate a long NP into their sentence. The long NPs also tended to be shifted to the end of the sentence, whereas short NPs tended to be positioned after the verb. Planning or producing responses with long NPs was especially difficult for older adults, although verb type and NP shift had similar costs for young and older adults. Pursuit rotor tracking during controlled sentence production reveals the effects of aging on sentence planning and production.

    This text serves as a thorough introduction to the rapidly developing field of positional games. This area constitutes an important branch of combinatorics, whose aim it is to systematically develop an extensive mathematical basis for a variety of two-player perfect information games. These range from such popular games as Tic-Tac-Toe and Hex to purely abstract games played on graphs and hypergraphs. The subject of positional games is strongly related to several other branches of combinatorics such as Ramsey theory, extremal graph and set theory, and the probabilistic method. These notes cover a variety of topics in positional games, including both classical results and recent important developments. They are presented in an accessible way and are accompanied by exercises of varying difficulty, helping the reader to better understand the theory. The text will benefit both researchers and graduate students in combinatorics and adjacent fields.

    Acoustic neuroma surgery is a procedure in which a benign mass is removed from the Internal Auditory Canal (IAC). Currently this surgical procedure requires manual drilling of the temporal bone followed by exposure and removal of the acoustic neuroma. This procedure is physically and mentally taxing to the surgeon. Our group is working to develop an Acoustic Neuroma Surgery Robot (ANSR) to perform the initial drilling procedure. Planning the ANSR's drilling region using pre-operative CT requires expertise and around 35 minutes' time. We propose an approach for automatically producing a resection plan for the ANSR that would avoid damage to sensitive ear structures and require minimal editing by the surgeon. We first compute an atlas-based segmentation of the mastoid section of the temporal bone, refine it based on the position of anatomical landmarks, and apply a safety margin to the result to produce the automatic resection plan. In experiments with CTs from 9 subjects, our automated process resulted in a resection plan that was verified to be safe in every case. Approximately 2 minutes were required in each case for the surgeon to verify and edit the plan to permit functional access to the IAC. We measured a mean Dice coefficient of 0.99 and surface error of 0.08 mm between the final and automatically proposed plans. These preliminary results indicate that our approach is a viable method for resection planning for the ANSR and drastically reduces the surgeon's planning effort.

    Purpose: To enable to detect the position of an moving object in a control rod position detector, stably in a digital manner at a high accuracy and free from the undesired effects of circumstantial conditions such as the reactor temperature. Constitution: Coils connected in parallel with each other are disposed along the passage of a moving object and variable resistors and relays are connected in series with each of the coils respectively. Light emitting diodes is connected in series with the contacts of the respective relays. The resistance value of the variable resistors are adjusted depending on the changes in the circumstantial conditions and temperature distribution upon carrying out the positional detection. When the object is inserted into a coils, the relevant relay is deenergized, by which the relay contacts are closed to light up the diode. In the same manner, as the object is successively inserted into the coils, the diodes are lighted-up successively thereby enabling highly accurate and stable positional detection in a digital manner, free from the undesired effects of the circumstantial conditions.

    Recently, pruritus has been recognised as an important association with neuromyelitis optica spectrum disorders (NMOSD). To determine the clinical and radiological characteristics of patients with NMOSD and pruritus. Among 57 consecutive patients with NMOSD, 15 (26.3% women) reported pruritus. All had aquaporin-4 (AQP4) antibodies. The mean age was 34.5 ± 9.1 years, age at onset was 31.3 ± 11.0 years and the duration of illness was 3.9 ± 3.1 years. Pruritus preceded the neurological disturbances in all the patients. Predominant patients experienced pruritus in the cervical dermatome (66.7%) followed by cervicothoracic region (13.3%), trigeminal nerve (13.3%) and lumbar region (6.7%). Lesions extending from cervicomedullary junction up to the thoracic segment was the most common site of affection (40%) followed by cervicothoracic (26.7%), cervicomedullary junction to cervical cord (13.3%), cervical cord (6.7%) and thoracic segment (6.7%). This report is one of the largest series reporting the close association of pruritus with onset of neurological symptoms in NMOSD. It highlights the importance of recognising this rare symptom which may help in making a correct diagnosis in a patient with suspected demyelinating disorder. In a patient with NMOSD, early treatment with immunomodulation during pruritus may prevent or minimise occurrence of neurological dysfunction.

    The purpose was to study correlations amongst IMRT DVH evaluation points and how their relaxation impacts the overall plan. 100 head‐and‐neck cancer cases, using the Eclipse treatment planning system with the same protocol, are statistically analyzed for PTV, brainstem, and spinal cord. To measure variations amongst the plans, we use (i) interquartile range (IQR) of volume as a function of dose, (ii) interquartile range of dose as a function of volume, and (iii) dose falloff. To determine correlations for institutional and ICRU goals, conditional probabilities and medians are computed. We observe that most plans exceed the median PTV dose (average D50 = 104% prescribed dose). Furthermore, satisfying D50 reduced the probability of also satisfying D98, constituting a negative correlation of these goals. On the other hand, satisfying D50 increased the probability of satisfying D2, suggesting a positive correlation. A positive correlation is also observed between the PTV V105 and V110. Similarly, a positive correlation between the brainstem V45 and V50 is measured by an increase in the conditional median of V45, when V50 is violated. Despite the imposed institutional and international recommendations, significant variations amongst DVH points can occur. Even though DVH aims are evaluated independently, sizable correlations amongst them are possible, indicating that some goals cannot be satisfied concurrently, calling for unbiased plan criteria.

    Discrepancies between planned and delivered movements of multi-leaf collimators (MLCs) are an important source of errors in dose distributions during radiotherapy. In this work we used machine learning techniques to train models to predict these discrepancies, assessed the accuracy of the model predictions, and examined the impact these errors have on quality assurance (QA) procedures and dosimetry. Predictive leaf motion parameters for the models were calculated from the plan files, such as leaf position and velocity, whether the leaf was moving towards or away from the isocenter of the MLC, and many others. Differences in positions between synchronized DICOM-RT planning files and DynaLog files reported during QA delivery were used as a target response for training of the models. The final model is capable of predicting MLC positions during delivery to a high degree of accuracy. For moving MLC leaves, predicted positions were shown to be significantly closer to delivered positions than were planned positions. By incorporating predicted positions into dose calculations in the TPS, increases were shown in gamma passing rates against measured dose distributions recorded during QA delivery. For instance, head and neck plans with 1%/2 mm gamma criteria had an average increase in passing rate of 4.17% (SD  =  1.54%). This indicates that the inclusion of predictions during dose calculation leads to a more realistic representation of plan delivery. To assess impact on the patient, dose volumetric histograms (DVH) using delivered positions were calculated for comparison with planned and predicted DVHs. In all cases, predicted dose volumetric parameters were in closer agreement to the delivered parameters than were the planned parameters, particularly for organs at risk on the periphery of the treatment area. By incorporating the predicted positions into the TPS, the treatment planner is given a more realistic view of the dose distribution as it will truly be

    2004-09-01

    Introduction/objective: The purpose of this study was to assess whether condylar position, as depicted by magnetic resonance imaging, was an indicator of disc morphology and position. Methods and material: One hundred and twenty two TMJs of 61 patients with temporomandibular joint disorder were examined. Condylar position, disc deformity and degree of anterior disc displacement were evaluated by using magnetic resonance imaging. Results and discussion: Posterior condyle position was found to be the main feature of temporomandibular joints with slight and moderate anterior disc displacement. No statistical significance was found between the condylar position, and reducing and nonreducing disc positions. On the other hand, superior disc position was found to be statistically significant for centric condylar position. Conclusion: It was concluded that posterior condyle position could indicate anterior disc displacement whereas there was no relation between the position of condyle and the disc deformity.

    Strategic planning is becoming essential to neuroradiology as the health care environment continues to emphasize cost efficiency, teamwork and collaboration. A strategic plan begins with a mission statement and vision of where the neuroradiology division would like to be in the near future. Formalized strategic planning frameworks, such as the strengths, weaknesses, opportunities and threats (SWOT), and the Balanced Scorecard frameworks, can help neuroradiology divisions determine their current position in the marketplace. Communication, delegation, and accountability in neuroradiology is essential in executing an effective strategic plan. Copyright © 2012 Elsevier Inc. All rights reserved.

    Traumatic minor cervical strains are common place in high-impact sports (e.g. tackling) and premature degenerative changes have been documented in sports people exposed to recurrent impact trauma (e.g. scrummaging in rugby) or repetitive forces (e.g. Formula 1 racing drivers, jockeys). While proprioceptive exercises have been an integral part of rehabilitation of injuries in the lower limb, they have not featured as prominently in the treatment of cervical injuries. However, head and neck position sense (HNPS) testing and re-training may have relevance in the management of minor sports-related neck injuries, and play a role in reducing the incidence of ongoing pain and problems with function. For efficacious programmes to be developed and tested, fundamental principles associated with proprioception in the cervical spine should be considered. Hence, this article highlights the importance of anatomical structures in the cervical spine responsible for position sense, and how their interaction with the CNS affects our ability to plan and execute effective purposeful movements. This article includes a review of studies examining position sense in subjects with and without pathology and describes the effects of rehabilitation programmes that have sought to improve position sense. In respect to the receptors providing proprioceptive information for the CNS, the high densities and complex arrays of spindles found in cervical muscles suggest that these receptors play a key role. There is some evidence suggesting that ensemble encoding of discharge patterns from muscle spindles is relayed to the CNS and that a pattern recognition system is used to establish joint position and movement. Sensory information from neck proprioceptive receptors is processed in tandem with information from the vestibular system. There are extensive anatomical connections between neck proprioceptive inputs and vestibular inputs. If positional information from the vestibular system is inaccurate or

    Israel maintained that the complex international system and worldwide political tension created a situation in which comprehensive plans of disarmament could not produce any positive result. The deadlock in the field of general and complete disarmament has brought Israel to the realization that one possible way to alleviate the stalemate could be progress by stages through partial measures of disarmament. Israel's position on non-proliferation indicates that the establishment of a nuclear-weapon-free-zone (NWFZ), as it relates to the Middle-East, could serve as a credible alternative to the unilateral adherence to the Non-Proliferation of Nuclear Weapon (NPT) and an effective measure of non-proliferation in the region.

  18. Indicators for Nuclear Power Development

    International Nuclear Information System (INIS)

    2015-01-01

    Considering the scale of nuclear power aspirations, the number of planned nuclear new builds and the prospects of a number of countries constructing their first nuclear power plants, there is a need to assess the broader context of nuclear energy programmes in areas of macro-and socioeconomic conditions, energy systems and nuclear power, and the environment. It is important to assess the degree to which introduction or expansion of nuclear power is beneficial under these specific circumstances. This publication provides a set of indicators for nuclear power development that can serve as a tool to help explore these issues. The indicators are meant to provide a first order assessment of the situation and identify the issues that present the benefits and challenges in a balanced and objective manner and thereby help guide more detailed evaluations in the next stage of planning and preparations. Methodology sheets are provided to help users in data collection, quantification and interpretation of the indicators. The application of the indicators set is flexible. Users can select a subset of indicators that are most relevant for the questions they wish to explore in a given study or decision making process

    The nuclear facilities need an extensive basis for ensuring their safety. An operating organization should conduct its operation and utilization important to the safety in accordance with approved procedures and regulations. The general aims of a management system for nuclear facilities are to improve the safety performance through a planning, control and supervision of safety related activities and to foster a strong safety culture. The effectiveness of a management system can be monitored and measured to confirm the ability of its processes to achieve the intended safety performance by an assessment of the operational performance. The Operational Safety Performance Indicators, also known as SPI, help an organization define and measure a progress with regard to safety activity goals. The elements of a SPI are quantifiable measurements that reflect the critical success factors of an organizational safety. Since 1995, efforts have been directed towards the elaboration of a framework for the establishment of an operational safety performance indicator program in nuclear power plants (NPP). IAEA-TECDOC-1141, 'Operational safety performance indicators for NPP' attempted to provide a frame work for an identification of performance indicators which have a relationship to the desired safety attributes, and therefore, to a safe plant operation. Three key attributes of a smooth operation, an operation with a low risk, and an operation with a positive safety attitude, were recommended, which are associated with a safe operation. Because these attributes cannot be directly measured, an indicator structure is expanded further until a level of easily quantifiable or directly measurable indicators is identified. The intention of this approach is to use quantitative information provided by the specific indicators and to analyze performance trends relative to established goals. The safety activities in HANARO have been continuously conducted to enhance its safe operation. HANARO

    Existing research on health plan performance examines whether variation in plans' scores is related to enrollee and health plan traits, primarily using cross-sectional research designs. This study extends that literature by incorporating data on market characteristics using a longitudinal framework. We estimate multivariate growth models that relate plan performance on standard measures to market and HMO characteristics using an unbalanced panel of data for 1998 to 2002. We find that HMO competition is not associated with better performance or greater rates of improvement in performance on the HEDIS chronic care measures. HMO penetration, on the other hand, is positively associated with HEDIS performance in several of the chronic care process-and-outcomes measures but not with a greater rate of improvement through time. Our analysis indicates that a significant percentage of the unexplained variation in quality improvement is because of permanent, unobserved plan-level characteristics that future research should strive to identify.

  2. Strategic considerations in planning a counterevacuation

    The Soviet Union has highly developed plans to evacuate their population centers in a nuclear confrontation. Their plans include construction of expedient shelters in the outlying areas and continued operation of their essential industry by commuting workers. If they should successfully implement their plan, a subsequent nuclear exchange with the United States would cost them far fewer casualties than they suffered in World War II. Without a corresponding evacuation, the US could lose from 50 to 70 percent of its population. This asymmetry in vulnerability, if allowed to persist, would seriously weaken the bargaining position of the US President. To restore the balance, a great reduction in vulnerability can be achieved most economically by planning a US counterevacuation as a response to a Soviet evacuation. Russian historical experience with murderous invaders, most recently in World War II, has made authoritarian defense measures involving civilians and property in peacetime quite acceptable in their culture. In the US, widescale use of private property and civilian participation in defense activity are not feasible until the development of a grave crisis. Hence US evacuation plans must differ in several important respects from the Soviet plans. However, this preliminary study indicates that the US has ample material resources to move and shelter its population at least as effectively as the Soviet Union. Perhaps the most critical disadvantage of the US is in morale, as evidenced by the widespread misconception that effective survival measures are not possible

    Developing an early warning model to predict the driver's mental workload (MWL) is critical and helpful, especially for new or less experienced drivers. The present study aims to investigate the correlation between new drivers' MWL and their work performance, regarding the number of errors. Additionally, the group method of data handling is used to establish the driver's MWL predictive model based on subjective rating (NASA task load index [NASA-TLX]) and six physiological indices. The results indicate that the NASA-TLX and the number of errors are positively correlated, and the predictive model shows the validity of the proposed model with an R 2 value of 0.745. The proposed model is expected to provide a reference value for the new drivers of their MWL by providing the physiological indices, and the driving lesson plans can be proposed to sustain an appropriate MWL as well as improve the driver's work performance.

    In this paper we argue that the use of the communicative theory of Jürgen Habermas in planning theory is problematic because it hampers an understanding of how power shapes planning. We posit an alternative approach based on the power analytics of Michel Foucault which focuses on "what is actually...... done", as opposed to Habermas`  focus on "what should be done". We discuss how the Foucauldian stance problematises planning, asking difficult questions about the treatment of legitimacy, rationality, knowledge and spatiality. We conclude that Foucault offers a type of analytic planning theory which...... offers better prospects than does Habermas for those interested in understanding and bringing about democratic social change through planning....

    By definition, forward planning is a process where input consists of conditions on beam configurations and parameters and output consists of dose distributions on target and critical structures, in contrast to inverse planning, where the opposite is true. For forward planning IMRT, criteria are as follows: (i) Plans created as an extension of standard 3D conformational planning; (ii) No significant increase in the complexity of the treatment planning or treatment delivery process; (3) Treatment verification using standard QA procedures; and process consists of the following steps: (i) Create a standard 3D conformational treatment plan; (ii) Copy one of the existing beams; (iii) Create control points: design new beam segments, blocking high dose areas; (iv) Repeat for all beams; (v) Re-compute dose; and (vi) Adjust control points weights to achieve desired dose distribution. A detailed exposition, with many clinical examples, is given for the breast, lung, and brain (P.A.)

    Purpose: To describe a newly designed proton pencil beam scanning (PBS) planning technique for radiotherapy of patients with bilateral oropharyngeal cancer, and to assess plan robustness. Methods: We treated 10 patients with proton PBS plans using 2 posterior oblique field (2F PBS) comprised of 80% single-field uniform dose (SFUD) and 20% intensity-modulated proton therapy (IMPT). All patients underwent weekly CT scans for verification. Using dosimetric indicators for both targets and organs at risk (OARs), we quantitatively compared initial plans and verification plans using student t-tests. We created a second proton PBS plan for each patient using 2 posterior oblique plus 1 anterior field comprised of 100% SFUD (3F PBS). We assessed plan robustness for both proton plan groups, as well as a photon volumetric modulated arc therapy (VMAT) plan group by comparing initial and verification plans. Results: The 2F PBS plans were not robust in target coverage. D98% for clinical target volume (CTV) degraded from 100% to 96% on average, with maximum change Δ D98% of −24%. Two patients were moved to photon VMAT treatment due to insufficient CTV coverage on verification plans. Plan robustness was especially weak in the low-anterior neck. The 3F PBS plans, however, demonstrated robust target coverage, which was comparable to the VMAT photon plan group. Doses to oral cavity were lower in the Proton PBS plans compared to photon VMAT plans due to no lower exit dose to the oral cavity. Conclusion: Proton PBS plans using 2 posterior oblique fields were not robust for CTV coverage, due to variable positioning of redundant soft tissue in the posterior neck. We designed 3-field proton PBS plans using an anterior field to avoid long heterogeneous paths in the low neck. These 3-field proton PBS plans had significantly improved plan robustness, and the robustness is comparable to VMAT photon plans

    Full Text Available In order to investigate the effects of range management plans on species diversity, richness and evenness in Semirum rangelands, 52 sites (28 with treated plan and 24 without treated plan were selected. The non-parametric indices for species richness (Margalof, Menhinick, Jacknife and counting method and species diversity (Simpson, Camargo, Smith and Wilson and modified Nee were compared in two management plans. The mean comparisons were made by independent T Student Test and Mann-Witheny U Test, and correlation was determined between diversity indices and vegetation parameters. Based on the results there was no significant difference between the two management systems regarding environmental features, while the implementation of range management plans caused significant reduction of stocking rate. Among the studied indices, evenness of species in sites without treated plan was significantly more than the sites with treated plan. The correlation matrix showed that there was a significant positive correlation between species richness and vegetation cover, production of perennial plans, and the rangeland condition and trend, while evenness showed significant negative correlation with these indices. Generally, implementation of range management plans has considerable effect on increasing climax species, dominance of Bromus tomentellus and it causes improvement of rangeland condition and reduction of evenness. This behavior could be explained by the balance between species competition and grazing pressure. Further, succession process of the studied communities demonstrates domination of some desirable species, high production and less diversity.

    Strategic planning and business planning are processes commonly employed by organizations that exist in competitive environments. Although it is difficult to prove a causal relationship between formal strategic/business planning and positive organizational performance, there is broad agreement that formal strategic and business plans are components of successful organizations. The various elements of strategic plans and business plans are not common in the vernacular of practicing physicians. As health care becomes more competitive, familiarity with these tools may grow in importance. Herein we provide an overview of formal strategic and business planning, and offer a roadmap for an interventional radiology-specific plan that may be useful for organizations confronting competitive and financial threats.

    Slovenian Nuclear Safety Administration (SNSA) division of nuclear and radiological safety inspection has developed systematic approach to their inspections. To be efficient in their efforts regarding regular and other types of inspections, in past years, the inspection plan has been developed. It is yearly based and organized on a such systematic way, that all areas of nuclear safety important activities of the licensee are covered. The inspection plan assures appropriate preparation for conducting the inspections, allows the overview of the progress regarding the areas to be covered during the year. Depending on the licensee activities and nature of facility (nuclear power plant, research reactor, radioactive waste storage, others), the plan has different levels of intensity of inspections and also their frequency. One of the basic approaches of the plan is to cover all nuclear and radiological important activities on such way, that all regulatory requests are fulfilled. In addition, the inspection plan is a good tool to improve inspection effectiveness based on previous experience and allows to have the oversight of the current status of fulfillment of planned inspections. Future improvement of the plan is necessary in the light of newest achievements on this field in the nuclear world, that means, new types of inspections are planned and will be incorporated into plan in next year.(author)

    Full Text Available This study examines factors associated with the likelihood of having a plan that includes a special needs trust among families that have disabled minor children. Descriptive analyses indicate that the top two reasons families provide for not having a plan are the inability to save and no perceived need. Among families that do indicate having a plan, most do not include a special needs trust. Multivariate analyses reveal that professional involvement (financial, legal, and mental health professionals is a key factor to increasing the likelihood of having a plan with a special needs trust. Families that have met with a financial advisor are 23 times more likely, and families who are encouraged to create a plan by a mental health professional are almost three times more likely, to have a plan that includes a special needs trust. Results from this study suggest that financial therapists are uniquely positioned to educate and ensure that appropriate plans are in place to provide for the future of children with special needs.

    The performance indicator development work of the US Nuclear Regulatory Commission (NRC) interoffice task group involved several major activities that included selection of candidate indicators for a trial program, data collection and review, validation of the trial indicators, display method development, interactions with the industry, and selection of an optimum set of indicators for the program. After evaluating 27 potential indicators against certain ideal attributes, the task group selected 17 for the trial program. The pertinent data for these indicators were then collected from 50 plants at 30 sites. The validation of the indicators consisted of two primary processes: logical validity and statistical analysis. The six indicators currently in the program are scrams, safety system actuations, significant events, safety system failures, forced outage rate, and equipment forced outages per 100 critical hours. A report containing data on the six performance indicators and some supplemental information is issued on a quarterly basis. The NRC staff is also working on refinements of existing indicators and development of additional indicators as directed by the commission

    Background and purpose: There is a widespread and increasing tendency to develop hospital performance indicators in the field of accreditation/certification systems and quality benchmarking. A study has been undertaken to develop a set of performance indicators for a typical radiotherapy Centre and to evaluate their ability to provide a continuous quality improvement. Materials and methods: A working group consisting of radiation oncologists, medical physicists and radiation technologists under the coordination of experts in health technology assessment has elaborated a set of general indicators able to monitor performances and the quality level of a typical radiotherapy Centre. The work has been carried out through four steps: a preliminary set of indicators was selected; data on these indicators were collected in a number of Italian radiotherapy Centres and medical physics Services; problems in collection and analysis of data were discussed; a final set of indicators was developed. Results: A final set of 13 indicators is here presented. They concern general structural and/or operational features, health physics activities and accuracy and technical complexity of the treatment. Conclusions: The indicators tested in a few Italian Centres of radiotherapy and medical physics Services are now ready to be utilized by a larger community

  18. Indicators of sustainable tourism

    Full Text Available The indicators, precisely describing the linkages between tourism and the environment, social and cultural base, are not easily available. How ever, some relevant organizations (WTO, EU, OECD, etc., institutions and experts, have been hardly working to create the indicators of sustainable tourism. Whereas the economic objectives are easily defined by the use of the traditional indicators used in national and business economics, it is very difficult to identify widely applicable environmental, social and cultural indicators. In order to stimulate and alleviate the process of sustainable tourism development, EU created the list of comparative indicators of sustainable tourism. In preparing this list, special attention is paid to identification of valid indicators of real tourism impacts on the social and cultural environment (the entire set of traditions, customs, history, hospitality and culture that characterize a given area, that is a very complex task. Assuming the fact that the related indicators have been analyzed in many European countries, this paper is focused on applying the related indicators in research of tourism development in villages of the Kosjerić community. .

    2015-09-01

    Full Text Available This paper deals with the evaluation of selected available indicators of living standards, divided into three groups, namely economic, environmental, and social. We have selected six countries of the European Union for analysis: Bulgaria, the Czech Republic, Hungary, Luxembourg, France, and Great Britain. The aim of this paper is to evaluate indicators measuring living standards and suggest the most important factors which should be included in the final measurement. We have tried to determine what factors influence each indicator and what factors affect living standards. We have chosen regression analysis as our main method. From the study of factors, we can deduce their impact on living standards, and thus the value of indicators of living standards. Indicators with a high degree of reliability include the following factors: size and density of population, health care and spending on education. Emissions of carbon dioxide in the atmosphere also have a certain lower degree of reliability.

    2002-01-01

    It has proven impossible to create an indicator capable of showing the state of the art in a single figure so as to determine the progress made in the 'radiation component' of environmental policy from the trends indicated. This is the conclusion following an investigation requested by the Ministry of Housing, Spatial Planning and the Environment in the framework of the environmental theme 'dispersion of radioactive substances and ionising radiation' to develop a radiation indicator comparable to the indicators for proprietary substances and pesticides. The most important reasons for failing to develop this indicator lie in the absence of both suitable policy targets and data for the calculations necessary for the indicator. Substituting policy targets with reference emissions, reference concentrations and reference doses would make it possible to define indicators for radiation protection. Here, environmental pressure indicators are proposed for nuclear installations and the process industry. The environment...

    The purpose of this document is to show a method for the fast recalculation of the PSA. To avoid the information loose, it is necessary to simplify the PSA models, or at least reorganize them. The method, introduced in this document, require that preparation, so we try to show, how to do that. This document is an introduction. This is the starting point of the work related to the development of the risk indicators. In the future, with the application of this method, we are going to show an everyday use of the PSA results to produce the indicators of the core damage risk. There are two different indicators of the plant safety performance, related to the core damage risk. The first is the core damage frequency indicator (CDFI), and the second is the core damage probability indicator (CDPI). Of course, we cannot describe all of the possible ways to use these indicators, rather we will try to introduce the requirements to establish such an indicator system and the calculation process

    Ryan, M.J.

    1978-01-01

    A reusable, tamper-indicating seal is comprised of a drum confined within a fixed body and rotatable in one direction therewithin, the top of the drum constituting a tray carrying a large number of small balls of several different colors. The fixed body contains parallel holes for looping a seal wire therethrough. The base of the drums carries cams adapted to coact with cam followers to lock the wire within the seal at one angular position of the drum. A channel in the fixed body, visible from outside the seal, adjacent the tray constitutes a segregated location for a small plurality of the colored balls. A spring in the tray forces colored balls into the segregated location at one angular position of the drum, further rotation securing the balls in position and the wires in the seal. A wedge-shaped plough removes the balls from the segregated location, at a different angular position of the drum, the wire being unlocked at the same postion. A new pattern of colored balls will appear in the segregated location when the seal is relocked

    Energy is an essential factor in overall efforts to achieve sustainable development. Countries striving to this end are seeking to reassess their energy systems with a view toward planning energy programmes and strategies in line with sustainable development goals and objectives. This paper summarizes the outcome of an international partnership initiative on indicators for sustainable energy development that aims to provide an analytical tool for assessing current energy production and use patterns at a national level. The proposed set of energy indicators represents a first step of a consensus reached on this subject by five international agencies-two from the United Nations system (the Department of Economic and Social Affairs and the International Atomic Energy Agency), two from the European Union (Eurostat and the European Environment Agency) and one from the Organization for Economic Cooperation and Development (the International Energy Agency). Energy and environmental experts including statisticians, analysts, policy makers and academics have started to implement general guidelines and methodologies in the development of national energy indicators for use in their efforts to monitor the effects of energy policies on the social, economic and environmental dimensions of sustainable development

    In facing future developments in health care, scenario planning offers a complementary approach to traditional strategic planning. Whereas traditional strategic planning typically consists of predicting the future at a single point on a chosen time horizon and mapping the preferred plans to address such a future, scenario planning creates stories about multiple likely potential futures on a given time horizon and maps the preferred plans to address the multiple described potential futures. Each scenario is purposefully different and specifically not a consensus worst-case, average, or best-case forecast; nor is scenario planning a process in probabilistic prediction. Scenario planning focuses on high-impact, uncertain driving forces that in the authors' example affect the field of radiology. Uncertainty is the key concept as these forces are mapped onto axes of uncertainty, the poles of which have opposed effects on radiology. One chosen axis was "market focus," with poles of centralized health care (government control) vs a decentralized private market. Another axis was "radiology's business model," with one pole being a unified, single specialty vs a splintered, disaggregated subspecialty. The third axis was "technology and science," with one pole representing technology enabling to radiology vs technology threatening to radiology. Selected poles of these axes were then combined to create 3 scenarios. One scenario, termed "entrepreneurialism," consisted of a decentralized private market, a disaggregated business model, and threatening technology and science. A second scenario, termed "socialized medicine," had a centralized market focus, a unified specialty business model, and enabling technology and science. A third scenario, termed "freefall," had a centralized market focus, a disaggregated business model, and threatening technology and science. These scenarios provide a range of futures that ultimately allow the identification of defined "signposts" that can

    Factor 4 is the goal of cutting our greenhouse gas emissions by 75% by 2050. Achieving this objective will necessitate radical changes in our practices, in particular concerning transport and housing; the measures currently implemented, such as positive-energy buildings, low-impact mobility and eco-neighbourhoods, will not be enough to meet this goal. These measures must be conceived in the framework of broad territorial planning that integrates environmental and energy objectives far upstream. To this end, the French Environment and Energy Management Agency (ADEME) and the French network of Urban Planning Agencies (FNAU), pursuing their missions in their respective areas of competence, have joined forces to make infrastructure and land use planning an integral part of the environmental and energy transition process. In 2013, the two organisations signed a partnership agreement and compiled an inventory of practices that are relevant to Factor 4 planning. This work was led by Epures, Saint-etienne urban planning agency, along with FNAU, drawing upon the expertise of a dozen urban planning agencies in precursor territories. This inventory describes the stakes, resources and strengths for each territory, which have led to cross-sectoral territorial planning exercises with ambitious environmental and energy objectives; the importance of evaluation in attaining these goals is emphasised. Current experience, questions and available methodological tools are summarised in this document, to encourage territories and help them design their planning policies along a trajectory to achieve Factor 4 goals. The compilation also aims to be a contribution to the COP21 climate conference

    Full Text Available Purpose: To evaluate the applicability, contributions, and adaptations required for a decision support model in the context of a business model's definition. The business model refers to 10 technological projects. Originality/gap/relevance/implications: The paper attempts to empirically validate the model proposed by Reis, Ladeira, and Fernandes (2015. In this regard, the paper facilitates the interpretation and application of concepts relevant to the business model's definition, thereby contributing to an estimation between theory and entrepreneurial practice. Key methodological aspects: The research is qualitative and adopts an action research methodology regarding 10 participating projects of the Incentive Program for Innovation held in the Universidade Federal de Ouro Preto, Minas Gerais. We conducted interviews with 38 professionals in order to understand the model's applicability in different contexts and to assess convergences and differences between each analyzed case. Summary of key results: The model's application proved to be relevant mainly for the early stages of business planning. The inclusion of the minimum viable product in the model helped with resource design and the development of a product with similar characteristics to market needs. It was suggested that the criteria used to assist the decision-making process were evaluated and selected by the team in accordance with the intended business strategy. Key considerations/conclusions: It is suggested that future research evaluates the inclusion of i risk analysis and a contingency plan for the proposed business model and ii the valuation of technology as an important step for projects that include the transfer of technology to established companies. Objetivo: Avaliar a aplicabilidade, contribuições e adequações necessárias ao modelo de auxílio à tomada de decisão quanto à definição do modelo de negócio no contexto de dez projetos tecnológicos oriundos do ambiente

    Purpose: We propose a workflow to improve access to stereotactic ablative radiation therapy (SABR) for rural patients. When implemented, a separate trip to the central facility for simulation can be eliminated. Two elements are required: (1) Fabrication of custom immobilization devices to match positioning on prior diagnostic CT (dxCT). (2) Remote radiation pre-planning on dxCT, with transfer of contours/plan to simulation CT (simCT) and initiation of treatment same-day or next day. In this retrospective study, we validated part 2 of the workflow using patients already treated with SABR for upper lobe lung tumors. Methods: Target/normal structures were contoured on dxCT; a plan was created and approved by the physician. Structures were transferred to simCT using deformable image registration and the plan was re-optimized on simCT. Plan quality was evaluated through comparison to gold-standard structures contoured on simCT and a gold-standard plan based on these structures. Workflow-generated plan quality in this study represents a worst-case scenario as these patients were not treated using custom immobilization to match dxCT position as would be done when the workflow is implemented clinically. Results: 5/6 plans created through the pre-planning workflow were clinically acceptable. For all six plans, the gold-standard GTV received full prescription dose, along with median PTV V95%=95.2% and median PTV D95%=95.4%. Median GTV DSC=0.80, indicating high degree of similarity between the deformed and gold-standard GTV contours despite small GTV sizes (mean=3.0cc). One outlier (DSC=0.49) resulted in inadequate PTV coverage (V95%=62.9%) in the workflow plan; in clinical practice, this mismatch between deformed/gold-standard GTV would be revised by the physician after deformable registration. For all patients, normal tissue doses were comparable to the gold-standard plan and well within constraints. Conclusion: Pre-planning SABR cases on diagnostic imaging generated

    This report proposes and describes in detail several air quality indicators that may be used to describe population exposure. The suggested indicators account for temporal and spatial patterns of pollution and movements of individuals between different micro-environments. The Air Quality Indicator /AQI) should represent both the spatial and temporal aspects of pollution exposure that may have important effects on health. Two indicators are needed, the Population Air Quality Indicator and the Individual Air Quality Indicator. Mean concentrations, 98th percentile and maximum values are the traditional indicators for estimating exposure. the temporal variability of PM-10 and NO 2 , however, is here described by means of: 1) The rate of change of pollution as the difference between two consecutive hourly values and of 2) episodes, described in terms of number, duration and winter episode period, maximum concentration in the episode and integrated episode exposure (episode AOT50/100). The spatial variation of AQIs can be described in several ways, e.g.: 1) Concentrations in neighbouring grid squares can be compared as an indication of spatial variation and 2) point estimates can be compared to grid values for a description of variation within a grid. Both methods are presented here. A test of the representativity of static point estimates for pollution exposure is to compare them to an estimate of air pollution exposure accounting for movements between different locations, obtained using diaries. The ultimate aim of AQIs is to describe the population exposure to ambient pollution. This is done by estimating the number of people exposed using different characteristics of AQIs. The data used to describe these indicators originates from dispersion modelling of short-term air pollution concentrations in Oslo. Two series of data are used. One represents hour-for hour concentrations in the 1 km 2 grid system covering the city of Oslo, winter 1994/95, calculated by the grid

    17 days were spent devoted to the effort of learning about China's educational approach to family planning in the hope of discovering how they are achieving their remarkable success in reducing population growth. As a member of the 1981 New York University/SIECUS Colloquim in China, it was necessary to rely on the translation provided by the excellent guides. Discussions were focused on questions prepared in advance about the topics that concerned the group. These observations, based on a short and limited exposure, cover the following areas: marriage and family planning policies; the family planning program; school programs; adult education; family planning workers; and unique aspects of the program. China has an official position on marriage and family planning that continues to undergo revisions. The new marriage law sets the minimum ages of marriage at 22 for men and 20 for women. Almost everyone marries, and an unmarried person over age 28 is a rarity. The family planning program in China is carried out by an extensive organizational network at national, provincial, and local government levels. Officials termed it a "propaganda campaign." Hospitals, clinics, and factories invariably displayed posters; a popular set of four presents the advantages of the 1 child family as follows: late marriage is best, for it allows more time to work and study; 1 child is best for the health of the mother; one gets free medical care for his/her child if a family has only 1 child; and there is more time to teach 1 child. The state operated television regularly explains the 1 child policy utilizing special films. According to 1 family planning official, "before marriage there is little sex." There are few abortions for unmarried women. Education about sex is for adults, for those persons who are about to be married. There is little if any sex education in schools. Sexual teaching is not generally acceptable, especially in the rural areas. By contrast, in Shanghai the physiology

    The concept of energy security is widely used, yet there is no consensus on its precise interpretation. In this research, we have provided an overview of available indicators for long-term security of supply (SOS). We distinguished four dimensions of energy security that relate to the availability, accessibility, affordability and acceptability of energy and classified indicators for energy security according to this taxonomy. There is no one ideal indicator, as the notion of energy security is highly context dependent. Rather, applying multiple indicators leads to a broader understanding. Incorporating these indicators in model-based scenario analysis showed accelerated depletion of currently known fossil resources due to increasing global demand. Coupled with increasing spatial discrepancy between consumption and production, international trade in energy carriers is projected to have increased by 142% in 2050 compared to 2008. Oil production is projected to become increasingly concentrated in a few countries up to 2030, after which production from other regions diversifies the market. Under stringent climate policies, this diversification may not occur due to reduced demand for oil. Possible benefits of climate policy include increased fuel diversity and slower depletion of fossil resources. (author)

    The Project Rulison Monitoring Plan has been developed as part of the U.S. Department of Energy (DOE) Office of Legacy Management's mission to protect human health and the environment. The purpose of the plan is to monitor fluids from gas wells for radionuclides that would indicate contamination is migrating from the Rulison detonation zone to producing gas wells, allowing action to be taken before the contamination could pose a risk. The Monitoring Plan (1) lists the contaminants present and identifies those that have the greatest potential to migrate from the detonation zone (radionuclide source term), (2) identifies locations that monitor the most likely transport pathways, (3) identifies which fluids will be sampled (gas and liquid) and why, (4) establishes the frequency of sampling, and (5) specifies the most practical analyses and where the analysis results will be reported. The plan does not affect the long-term hydrologic sampling conducted by DOE since 1972, which will continue for the purpose of sampling shallow groundwater and surface water near the site. The Monitoring Plan was developed in anticipation of gas wells being drilled progressively nearer the Rulison site. DOE sampled 10 gas wells in 1997 and 2005 at distances ranging from 2.7 to 7.6 miles from the site to establish background concentrations for radionuclides. In a separate effort, gas industry operators and the Colorado Oil and Gas Conservation Commission (COGCC) developed an industry sampling and analysis plan that was implemented in 2007. The industry plan requires the sampling of gas wells within 3 miles of the site, with increased requirements for wells within 1 mile of the site. The DOE plan emphasizes the sampling of wells near the site (Figure 1), specifically those with a bottom-hole location of 1 mile or less from the detonation, depending on the direction relative to the natural fracture trend of the producing formation. Studies indicate that even the most mobile

  4. Minimum risk trigger indices

    Tingey, F.H.

    1979-01-01

    A viable safeguards system includes among other things the development and use of indices which trigger various courses of action. The usual limit of error calculation provides such an index. The classical approach is one of constructing tests which, under certain assumptions, make the likelihood of a false alarm small. Of concern also is the test's failure to indicate a loss (diversion) when in fact one has occurred. Since false alarms are usually costly and losses both costly and of extreme strategic sinificance, there remains the task of balancing the probability of false alarm and its consequences against the probability of undetected loss and its consequences. The application of other than classical hypothesis testing procedures are considered in this paper. Using various consequence models, trigger indices are derived which have certain optimum properties. Application of the techniques would enhance the material control function

    A temperature indicating device comprises a plurality of planar elements some undergoing a reversible change in appearance at a given temperature the remainder undergoing an irreversible change in appearance at a given temperature. The device is useful in indicating the temperature which an object has achieved as well as its actual temperature. The reversible change is produced by liquid crystal devices. The irreversible change is produced by an absorbent surface carrying substances e.g. waxes which melt at predetermined temperatures and are absorbed by the surface; alternatively paints may be used. The device is used for monitoring processes of encapsulation of radio active waste. (author)

    Today selective coronary angiography, introduced by Sones in 1957, is used as clinical routine for diagnosing morphological changes in the coronary arteries. Hitherto, more recent techniques such as digital subtraction angiography cannot provide comparable information. Strict criteria for its indication depending on possible therapeutic consequences, have to be applied, although the risk is low with a letality of 0.01 to 0.05 percent. Radionuclear investigations can be used as additional tool in selected cases. The careful indication for coronary angiography usually implies the possible need for coronary bypass graft surgery of balloon angioplasty. (orig./MG) [de

  10. Robustness of IPSA optimized high-dose-rate prostate brachytherapy treatment plans to catheter displacements.

    2016-06-01

    Inverse planning simulated annealing (IPSA) optimized brachytherapy treatment plans are characterized with large isolated dwell times at the first or last dwell position of each catheter. The potential of catheter shifts relative to the target and organs at risk in these plans may lead to a more significant change in delivered dose to the volumes of interest relative to plans with more uniform dwell times. This study aims to determine if the Nucletron Oncentra dwell time deviation constraint (DTDC) parameter can be optimized to improve the robustness of high-dose-rate (HDR) prostate brachytherapy plans to catheter displacements. A set of 10 clinically acceptable prostate plans were re-optimized with a DTDC parameter of 0 and 0.4. For each plan, catheter displacements of 3, 7, and 14 mm were retrospectively applied and the change in dose volume histogram (DVH) indices and conformity indices analyzed. The robustness of clinically acceptable prostate plans to catheter displacements in the caudal direction was found to be dependent on the DTDC parameter. A DTDC value of 0 improves the robustness of planning target volume (PTV) coverage to catheter displacements, whereas a DTDC value of 0.4 improves the robustness of the plans to changes in hotspots. The results indicate that if used in conjunction with a pre-treatment catheter displacement correction protocol and a tolerance of 3 mm, a DTDC value of 0.4 may produce clinically superior plans. However, the effect of the DTDC parameter in plan robustness was not observed to be as strong as initially suspected.

    The State Office for Nuclear Safety uses three sets of indicators describing the following aspects of a favourable nuclear power plant operation: smooth operation in normal circumstances, low risk to the population, and operation with a positive safety attitude. These are three safety-related areas for assessment. Each area has its own set of indicators. Overall operational safety performance indicators were identified for each attribute. From this point, a level of strategic indicators was developed, and finally, a set of specific indicators was set up. While neither the overall indicators nor the strategic indicators are directly measurable, the specific indicators are directly measurable and are targeted during inspection. (author)

    1978-12-01

    In this work is developed principles for statistical test plans for availability compliance tests. Failure terminated and time terminated fixed size plans are considered as well as sequential test plans without and with failure and time truncation. The suggested methods are evaluated with respect to some important characteristics, namely the average number of failures to termination, the duration of the test and the operating characteristic function. The methods used are based on the assumption that up- and down-times can be considered gamma distributed. Simulation studies indicate that the methods are robust against reasonable deviations in distribution assumptions for the down-times. In the work is also outlined technical conditions and prerequisites applicable to availability compliance tests in general. The approach choosen seems very promising and is worth further development. It is based on the same fundamental principles as present is used in International standardization of equipment reliability testing. (author)

    The clear value of economic data and analysis to decisionmakers has motivated them to mandate the creation of extensive global economic data sets. This chapter contains a set of these basic economic data, which provides the context for understanding the causes and the consequences of many of the decisions that affect the world's resources. Many traditional economic indicators fail to account for the depletion or deterioration of natural resources, the long-term consequences of such depletion, the equitable distribution of income within a country, or the sustainability of current economic practices. The type of measurement shown here, however, is still useful in showing the great differences between the wealthiest and the poorest countries. Tables are given on the following: Gross national product and official development assistance 1969-89; External debt indicators 1979-89; Central government expenditures; and World commodity indexes and prices 1975-89

    Trochlear dysplasia is a well-described risk factor for patellar instability. Trochleoplasty has emerged as a procedure within the surgical armamentarium for patellar instability, yet its role is unclear. A variety of trochleoplasty procedures have emerged. The purpose of this review is to clarify indications for trochleoplasty, outline the technical steps involved in performing common trochleoplasties and report the published outcomes and potential complications of these procedures. Patellar instability with severe trochlear dysplasia is the main indication for trochleoplasty. Three types of trochleoplasty have emerged: (1) lateral facet elevation; (2) sulcus deepening; and (3) recession wedge. Deepening and recession wedge trochleoplasties are the most commonly performed. Trochleoplasty is a surgical option for addressing patellar instability in patients with severe trochlear dysplasia. Deepening and recession wedge trochleoplasties that address Dejour B and D dysplastic trochleas are the most studied, with both short- and midterm outcomes reported. Long-term outcomes are lacking and comparative studies are needed.

  3. Lichens as bio indicators

    International Nuclear Information System (INIS)

    2003-01-01

    This publication discusses the use of lichens as biological indicators. Perennial growth, long life, efficient take-up of mineral nutrients from air and rain and small loss of nutrition are properties that make lichens suitable as biological indicators. In surveys and monitoring, species diversity and coverage by organisms that live as epiphytes on tree trunks have been the most commonly used parameters. A decline in the occurrence of this type of lichen is often related to the content of sulphur compounds in the air and it has been demonstrated that many species are sensitive to sulphur dioxide. It is also known that the growth of many types of lichens increases with a moderate increase in available nitrogen. In South Norway, pollution sensitive species such as Bryoria spp. have advanced strongly, which is probably due to less sulphur in the rain and a higher content of nutrition in the form of nitrate and ammonium

    The paper presents comparative analyses of two publication point systems, The Norwegian and the in-house system from the interdiscplinary Danish Institute for International Studies (DIIS), used as case in the study for publications published 2006, and compares central citation-based indicators...... with novel publication point indicators (PPIs) that are formalized and exemplified. Two diachronic citation windows are applied: 2006-07 and 2006-08. Web of Science (WoS) as well as Google Scholar (GS) are applied to observe the cite delay and citedness for the different document types published by DIIS...... for all document types. Statistical significant correlations were only found between WoS and GS and the two publication point systems in between, respectively. The study demonstrates how the nCPPI can be applied to institutions as evaluation tools supplementary to JCI in various combinations...

    Individuals with chronic conditions can benefit from formulating action plans to engage in regular physical activity. However, the content and the successful translation of plans into action, so-called plan enactment, are rarely adequately evaluated. The aim of this study was to describe the content of user-specified plans and to examine whether participants were more likely to enact their plans if these plans were highly specific, viable, and instrumental. The study presents secondary analyses from a larger behavioural intervention in cardiac and orthopaedic rehabilitation. The content of 619 action plans from 229 participants was evaluated by two independent raters (i.e., qualitative analyses and ratings of specificity) and by participants themselves (i.e., instrumentality and viability). Plan enactment was also measured via self-reports. Multilevel analyses examined the relationship between these plan characteristics and subsequent plan enactment, and between plan enactment and aggregated physical activity. Participants preferred to plan leisure-time physical activities anchored around time-based cues. Specificity of occasion cues (i.e., when to act) and highly instrumental plans were positively associated with plan enactment. Interestingly, individuals who planned less specific behavioural responses (i.e., what to do) were more likely to enact their plans. Plan enactment was positively associated with aggregated behaviour. Interventions should not only emphasize the importance of planning, but also the benefits of formulating specific contextual cues. Planning of the behavioural response seems to require less precision. Allowing for some flexibility in executing the anticipated target behaviour seems to aid successful plan enactment. Statement of Contribution What is already known on this subject? Action planning interventions are efficacious in promoting health behaviour. Characteristics of plan content (i.e., specificity) matter for unconditional behaviour

    Critically ill patients require regular body position changes to minimize the adverse effects of bed rest, inactivity and immobilization. However, uncertainty surrounds the effectiveness of lateral positioning for improving pulmonary gas exchange, aiding drainage of tracheobronchial secretions and preventing morbidity. In addition, it is unclear whether the perceived risk levied by respiratory and haemodynamic instability upon turning critically ill patients outweighs the respiratory benefits of side-to-side rotation. Thus, lack of certainty may contribute to variation in positioning practice and equivocal patient outcomes. To evaluate effects of the lateral position compared with other body positions on patient outcomes (mortality, morbidity and clinical adverse events) in critically ill adult patients. (Clinical adverse events include hypoxaemia, hypotension, low oxygen delivery and global indicators of impaired tissue oxygenation.) We examined single use of the lateral position (i.e. on the right or left side) and repeat use of the lateral position (i.e. lateral positioning) within a positioning schedule. We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 5), MEDLINE (1950 to 23 May 2015), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1937 to 23 May 2015), the Allied and Complementary Medicine Database (AMED) (1984 to 23 May 2015), Latin American Caribbean Health Sciences Literature (LILACS) (1901 to 23 May 2015), Web of Science (1945 to 23 May 2015), Index to Theses in Great Britain and Ireland (1950 to 23 May 2015), Trove (2009 to 23 May 2015; previously Australasian Digital Theses Program (1997 to December 2008)) and Proquest Dissertations and Theses (2009 to 23 May 2015; previously Proquest Digital Dissertations (1980 to 23 May 2015)).

    Physical 3D treatment planning provides a pool of parameters describing dose distributions. It is often useful to define conformal indices to enable quicker evaluation. However, the application of individual indices is controversial and not always effective. The aim of this study was to design a quick check of dose distributions based on several indices detecting underdosages within planning target volumes (PTVs) and overdosages in normal tissue. Dose distributions of 215 cancer patients were considered. Treatment modalities used were three-dimensional conformal radiotherapy (3DCRT), radiosurgery, intensity-modulated radiotherapy (IMRT), intensity-modulated arc therapy (IMAT) and tomotherapy. The volumes recommended in ICRU 50 and 83 were used for planning and six conformation and homogeneity indices were selected: CI, CN, C{sub ICRU}, COV, C{sub ∇}, and HI. These were based on the PTV, the partial volume covered by the prescribed isodose (PI; PTV{sub PI}), the treated volume (TV{sub PI}), near maximum D{sub 2} and near minimum D{sub 98}. Results were presented as a hexagon - the corners of which represent the values of the indices - and a modified test function F (Rosenbrock's function) was calculated. Results refer to clinical examples and mean values, in order to allow evaluation of the power of F and hexagon-based decision support procedures in detail and in general. IMAT and tomotherapy showed the best values for the indices and the lowest standard deviation followed by static IMRT. DCRT and radiosurgery (e.g. CN: IMAT 0.85 ± 0.06; tomotherapy 0.84 ± 0.06; IMRT 0.83 ± 0.07; 3DCRT 0.65 ± 0.08; radiosurgery 0.64 ± 0.11). In extreme situations, not all indices reflected the situation correctly. Over- and underdosing of PTV and normal tissue could be qualitatively assessed from the distortion of the hexagon in graphic analysis. Tomotherapy, IMRT, IMAT, 3DCRT and radiosurgery showed increasingly distorted hexagons, the type of distortion indicating

    International Nuclear Information System (INIS)

    1993-01-01

    In November 1989, the Office of Environmental Restoration and Waste Management (EM) was formed within the US Department of Energy (DOE). The EM Program was born of the recognition that a significant national effort was necessary to clean up over 45 years' worth of environmental pollution from DOE operations, including the design and manufacture of nuclear materials and weapons. Within EM, the Deputy Assistant Secretary for Environmental Restoration (EM-40) has been assigned responsibility for the assessment and cleanup of areas and facilities that are no longer a part of active DOE operations, but may be contaminated with varying levels and quantifies of hazardous, radioactive, and n-mixed waste. Decontamination and decommissioning (D ampersand D) activities are managed as an integral part of Envirorunental Restoration cleanup efforts. The Office of Environmental Restoration ensures that risks to the environment and to human health and safety are either eliminated or reduced to prescribed, acceptable levels. This Strategic Plan has been developed to articulate the vision of the Deputy Assistant Secretary for Environmental Restoration and to crystallize the specific objectives of the Environmental Restoration Program. The document summarizes the key planning assumptions that guide or constrain the strategic planning effort, outlines the Environmental Restoration Program's specific objectives, and identifies barriers that could limit the Program's success

    Purpose: Automate brachytherapy treatment plan quality check using Eclipse v13.6 scripting API based on pre-configured rules to minimize human error and maximize efficiency. Methods: The HDR Precheck system is developed based on a rules-driven approach using Eclipse scripting API. This system checks for critical plan parameters like channel length, first source position, source step size and channel mapping. The planned treatment time is verified independently based on analytical methods. For interstitial or SAVI APBI treatment plans, a Patterson-Parker system calculation is performed to verify the planned treatment time. For endobronchial treatments, an analytical formula from TG-59 is used. Acceptable tolerances were defined based on clinical experiences in our department. The system was designed to show PASS/FAIL status levels. Additional information, if necessary, is indicated appropriately in a separate comments field in the user interface. Results: The HDR Precheck system has been developed and tested to verify the treatment plan parameters that are routinely checked by the clinical physicist. The report also serves as a reminder or checklist for the planner to perform any additional critical checks such as applicator digitization or scenarios where the channel mapping was intentionally changed. It is expected to reduce the current manual plan check time from 15 minutes to <1 minute. Conclusion: Automating brachytherapy plan prechecks significantly reduces treatment plan precheck time and reduces human errors. When fully developed, this system will be able to perform TG-43 based second check of the treatment planning system’s dose calculation using random points in the target and critical structures. A histogram will be generated along with tabulated mean and standard deviation values for each structure. A knowledge database will also be developed for Brachyvision plans which will then be used for knowledge-based plan quality checks to further reduce

    1994-01-01

    Protecting sensitive items from undetected tampering in an unattended environment is crucial to the success of non-proliferation efforts relying on the verification of critical activities. Tamper Indicating Packaging (TIP) technologies are applied to containers, packages, and equipment that require an indication of a tamper attempt. Examples include: the transportation and storage of nuclear material, the operation and shipment of surveillance equipment and monitoring sensors, and the retail storage of medicine and food products. The spectrum of adversarial tampering ranges from attempted concealment of a pin-hole sized penetration to the complete container replacement, which would involve counterfeiting efforts of various degrees. Sandia National Laboratories (SNL) has developed a technology base for advanced TIP materials, sensors, designs, and processes which can be adapted to various future monitoring systems. The purpose of this technology base is to investigate potential new technologies, and to perform basic research of advanced technologies. This paper will describe the theory of TIP technologies and recent investigations of TIP technologies at SNL

    Of 1,327 children younger than two in 1986 whose mothers were participants in the National Longitudinal Survey of Youth, 61% were wanted, 34% were mistimed and 5% were unwanted. Planning status is associated with the level of developmental resources the child receives at home: At ages one and older, mistimed and unwanted children score significantly lower on a scale measuring opportunity for skill development and on a scale measuring nonauthoritarian parenting style than their wanted peers; by preschool age, they also have significantly less-positive relationships with their mothers. Measures of the direct effects of planning status on development also indicate that mistimed and unwanted children are at a disadvantage: Those younger than two have higher mean scores for fearfulness than wanted infants and lower scores for positive affect; unintended preschoolers score lower on a measure of receptive vocabulary.

    A tamper-indicating device is described. The device has a transparent or translucent cylindrical body that includes triboluminescent material, and an outer opaque layer that prevents ambient light from entering. A chamber in the body holds an undeveloped piece of photographic film bearing an image. The device is assembled from two body members. One of the body members includes a recess for storing film and an optical assembly that can be adjusted to prevent light from passing through the assembly and exposing the film. To use the device with a hasp, the body members are positioned on opposite sides of a hasp, inserted through the hasp, and attached. The optical assembly is then manipulated to allow any light generated from the triboluminescent materials during a tampering activity that damages the device to reach the film and destroy the image on the film.

    The present invention provides an apparatus and method whereby the reliability and tamper-resistance of tamper indicators can be improved. A flexible connector may be routed through a latch for an enclosure such as a door or container, and the free ends of the flexible connector may be passed through a first locking member and firmly attached to an insert through the use of one or more attachment members such as set screws. A second locking member may then be assembled in interlocking relation with the first locking member to form an interlocked assembly around the insert. The insert may have one or more sharp projections extending toward the first or second locking member so that any compressive force applied in an attempt to disassemble the interlocked assembly results in permanent, visible damage to the first or second locking member.

    Rose, F

    1970-01-01

    Although lichens are generally considered to be of little use to man, their sensitivity to air pollution makes them good biological indicators. The author describes how this feature can help to establish relative degrees of air pollution. He notes areas where lichens are reduced in number and vigor, and some in which they have disappeared altogether. He challenges the idea that dryness is responsible, since they have also disappeared from damp woodland areas. Experimental work supports the view that sulfur dioxide is the major factor rather than smoke, although there is no definitive proof. Lichen damage correlates best with mean winter levels of air pollution by SO/sub 2/. 16 references, 1 figure.

    1986-01-01

    It is the aim of this paper, intended more as a general outline than a comprehensive review, to elucidate the most prominent events in the sequence of radiation induced cytological changes in the hemopoietic system taking its functional organisation and the cytokinetics of blood cell production into consideration. As could be shown, there are about ten different categories of quantitative and qualitative parameters based on methods ranging from stem cell determinations to tests for mature blood cell function that in principle are available for assessment of radiation damage to the bone marrow and that have been applied to men exposed to ionizing radiation. Some of these indicator systems have proven for a long period of time to be of essential value and to be quite feasible in practice under routine conditions. Considerable methodological progress, however, is needed for others before decisions about their practical applicability can be made. (orig.)

  8. Flammability Indices for Refrigerants

    Science.gov (United States)

    Kataoka, Osami

    This paper introduces a new index to classify flammable refrigerants. A question on flammability indices that ASHRAE employs arose from combustion test results of R152a and ammonia. Conventional methods of not only ASHRAE but also ISO and Japanese High-pressure gas safety law to classify the flammability of refrigerants are evaluated to show why these methods conflict with the test results. The key finding of this paper is that the ratio of stoichiometric concentration to LFL concentration (R factor) represents the test results most precisely. In addition, it has excellent correlation with other flammability parameters such as flame speed and pressure rise coefficient. Classification according to this index gives reasonable flammability order of substances including ammonia, R152a and carbon monoxide. Theoretical background why this index gives good correlation is also discussed as well as the insufficient part of this method.

    Full Text Available Congenital heart diseases are encountered in 0.8% of live births and are among the most frequently diagnosed malformations. At least half of these anomalies end up with death or require surgical interventions and are responsible for 30% of the perinatal mortality. Fetal echocardiography is the sum of knowledge, skill and orientation rather than knowing the embryologic details of the fetal heart. The purpose of fetal echocardiography is to document the presence of normal fetal cardiac anatomy and rhythm in high risk group and to define the anomaly and arrhythmia if present. A certain sequence should be followed during the evaluation of fetal heart. Sequential segmental analysis (SSA and basic definition terminology made it possible to determine a lot of complex cardiac anomalies during prenatal period. By the end of 1970’s, Shinebourne started using sequential segmental analysis for fetal cardiac evaluation and today, prenatal diagnosis of congenital heart disease is possible without any confusion. In this manner, whole fetal heart can be evaluated as the relation of three segments (atria, ventricles and the great arteries with each other, irrelevant of complexity of a possible cardiac anomaly. Presence of increased nuchal thickness during early gestation and abnormal four-chamber-view during ultrasonography by the obstetrician presents a clear indication for fetal echocardiography,however, one should keep in mind that 80-90% of the babies born with a congenital heart disease do not have a familial or maternal risk factor. In addition, it should be remembered that expectant mothers with diabetes mellitus pose an indication for fetal echocardiography.

    The siting of wind farms is becoming an increasingly important issue in the Netherlands. This paper gives an overview of the current situation concerning the planning of wind farms. We will pay attention to: Wind energy in official Dutch planning policy. To select the optimal sites, the government has made an administrative agreement with the 7 windy provinces. Nevertheless, wind energy is still fighting for a rightful position in physical planning policy. Some examples will illustrate this. Studies on siting and siting problems in the Netherlands. In order to gain more insight into aspects of wind farming several studies have been executed. In this paper special attention will be paid to the results of a study on the potential impact of large windturbine clusters on an existing agricutural area. Experiences with siting of wind farms in the Netherlands. Based on experiences with the planning and realization of farms, this paper gives the main problems. In the final part of the paper we present some general conclusions. Generally speaking, the knowledge is available for selecting optimal sites in the Netherlands. The basic problems for wind farming nowadays seem to be the visual impact and actually obtaining the ground. Nevertheless, there do seem to be enough sites for realizing the goals in the Netherlands.

    Full Text Available Poucas cidades brasileiras possuem planejamento efetivo para a arborização de suas vias públicas, com a definição de objetivos e de possíveis metas qualitativas e quantitativas. Outro aspecto das cidades brasileiras é a questão da baixa diversidade de espécies encontrada, prevalecendo a homogeneidade e, portanto, a possível dizimação da população arbórea pela ocorrência de uma praga ou uma doença. Os chamados índices de riqueza ou variedade são úteis como indicadores de diversidade, podendo ser utilizados nas decisões de manejo. Neste trabalho foram avaliados os índices de Shannon-Wiener e Odum; para tanto, utilizou-se o censo da arborização viária da Estância de Águas de São Pedro. Foram definidos índices máximos e mínimos de diversidade, que possibilitaram a quantificação de espécies e o número de árvores em cada via pública, subsidiando o planejamento do manejo, como introdução de novas espécies e de novos indivíduos, remoções de árvores e prioridades de intervenção.Few Brazilian cities have an effective planning for street arborization, comprising the objectives to be achieved and possible qualitative and quantitative goals. Another problem of Brazilian cities is the low species diversity, prevailing species homogeneity, which may lead to great losses of trees due to the incidence of specific pests or diseases. The richness or diversity indexes are useful as diversity indicators and can be useful in management decision making. The Shannon-Wiener and the Odum indexes were evaluated by means of carrying out a street census in Aguas de Sao Pedro Resort. Maximum and minimum diversity indexes were calculated, allowing the quantification of species and number of trees in each street, providing the foundation of a management plan, which included the introduction of new species and new individuals, removal of trees and intervention priorities.

    as a territorial container, in which the social merges into regional and national entities. Correspondingly, movement is only interpreted as a derived demand, ignoring its integrative aspect as precondition of participation and part of network capital. On the other hand, the spatiality of the economy...... is represented as something outside and fluid which is meant to be channelled into the territorial containers by means of regional development and spatial planning. These representations of the social suggest a territorialized culturally integrated society as the unquestioned frame of reference which has lost...

    This article examines the extent to which the status of women is related to awareness, knowledge, and practice of family planning in India. It uses both macro-level data for the states of India and date from household surveys and field studies to assess the extent of interaction between the women's status indicators and family planning indicators. Results show a definite statistical relationship between women's status and women's ability to control fertility. The strongest relationship to adoption of family planning is the educational attainment of women, followed by age at marriage, and women's work participation, particularly in nonagricultural activities. Evidence from various surveys on the effects of crucial variables on reproductive behavior include 1) a marked reduction in fertility with increases in the educational level; 2) lower fertility for working women, and especially for non-manual workers; 3) a reduction in fertility with increases in age at marriage; and 4) a higher percentage of couples practicing family planning who have 2 or more surviving children, particularly if they have boys. A 1972 survey of 3 Indian states showed that 1) husbands impose a variety of restrictions on wives, with rural husbands placing more restrictions than urban husbands; 2) women's role in decision making in household affairs is positively correlated with the degree of awareness and knowledge of contraceptives as well as adoption of family planning; and 3) interspousal communication was significantly related to the practice of family planning in both rural and urban areas. In conclusion, to help encourage adoption of family planning and reduce fertility, India should 1) emphasize education for women, 2) enforce the legal minimum age at marriage, 3) promote employment opportunities for women, 4) improve women's role in decision making, and 5) encourage interspousal communication in family affairs.

    Since 1995, KNMI published a series of books(1), presenting an annual reconstruction of weather and climate in the Low Countries, covering the period AD 763-present, or roughly, the last millennium. The reconstructions are based on the interpretation of documentary sources predominantly and comparison with other proxies and instrumental observations. The series also comprises a number of classifications. Amongst them annual classifications for winter and summer temperature and for winter and summer dryness-wetness. The classification of temperature have been reworked into peer reviewed (2) series (AD 1000-present) of seasonal temperatures and temperature indices, the so called LCT (Low Countries Temperature) series, now incorporated in the Millennium databases. Recently we started a study to convert the dryness-wetness classifications into a series of precipitation; the so called LCP (Low Countries Precipitation) series. A brief outline is given here of the applied methodology and preliminary results. The WMO definition for meteorological drought has been followed being that a period is called wet respectively dry when the amount of precipitation is considerable more respectively less than usual (normal). To gain a more quantitative insight for four locations, geographically spread over the Low Countries area (De Bilt, Vlissingen, Maastricht and Uccle), we analysed the statistics of daily precipitation series, covering the period 1900-present. This brought us to the following definition, valid for the Low Countries: A period is considered as (very) dry respectively (very) wet if over a continuous period of at least 60 days (~two months) cq 90 days (~three months) on at least two out of the four locations 50% less resp. 50% more than the normal amount for the location (based on the 1961-1990 normal period) has been measured. This results into the following classification into five drought classes hat could be applied to non instrumental observations: Very wet period
