    Full Text Available Background: Idiopathic pulmonary fibrosis (IPF is a chronic, progressive lung disease that usually results in respiratory failure and death. Pirfenidone was approved as the first licensed therapy for IPF in Europe based on phase III trials where patients with a forced vital capacity (FVC >50% of predicted were included. The aim of this study was to characterise patients treated with pirfenidone in Swedish clinical practice and to describe the adherence to the reimbursement restriction since reimbursement was only applied for patients with FVC below 80% of predicted. Methods: This was a retrospective, observational chart review of IPF patients treated with pirfenidone from three Swedish university clinics. Patients initiated on treatment during the period 28 June 2012 to 20 November 2014 were included. Data on patient characteristics, basis of diagnosis, treatment duration, quality of life, and adverse drug reactions (ADRs were collected from medical charts. Results: Forty-four patients were screened and 33 were included in the study. The mean treatment duration from start of pirfenidone until discontinuation or end of study was 38 weeks. At the initiation of pirfenidone treatment, FVC was 62.7% (12.1 [mean (SD], diffusion capacity (DLco was 45.1% (13.8 of predicted, and the ratio of forced expiratory volume on 1 sec (FEV1 to FVC was 0.78 (0.1. The percentage of patients with an FVC between 50 and 80% was 87%. Ten of the patients had ADRs including gastrointestinal and skin-related events, cough and signs of impaired hepatic function, but this led to treatment discontinuation in only two patients. Conclusion: Data from this chart review showed that adherence to the Swedish reimbursement restriction was followed in the majority of patients during the study period. At the start of pirfenidone treatment, lung function, measured as FVC, was lower in the present cohort of Swedish IPF patients compared with other registry and real-life data. About a

    Seizures are a hallmark manifestation of tuberous sclerosis complex, yet data characterizing resource utilization are lacking. This retrospective chart review was performed to assess the economic burden of tuberous sclerosis complex with neurologic manifestations. Demographic and resource utilization data were collected for 95 patients for up to 5 years after tuberous sclerosis complex diagnosis. Mean age at diagnosis was 3.1 years, with complex partial and infantile spasms as the most common seizure types. In the first 5 years post-diagnosis, 83.2% required hospitalization, 30.5% underwent surgery, and the majority of patients (90.5%) underwent ≥3 testing procedures. In 79 patients with a full 5 years of data, hospitalizations, intensive care unit stays, diagnostic testing, and rehabilitation services decreased over the 5-year period. Resource utilization is cost-intensive in children with tuberous sclerosis complex and associated seizures during the first few years following diagnosis. Improving seizure control and reducing health care costs in this population remain unmet needs. PMID:22772159

    Several studies have described a wide spectrum of hyperandrogenism diseases, many of which are difficult to distinguish from each other. In order to better understand diseases of hyperandrogenism, the authors performed a retrospective study of the cutaneous features and metabolic findings in women with hyperandrogenism. A retrospective chart analysis compiled by three dermatologists in both academic and private settings was performed, including patients presenting with > or = 2 manifestations of hyperandrogenism. Relevant dermatologic and associated manifestations and laboratory and imaging study findings were reviewed. Moderate to severe acne was the most common manifestation. Other common manifestations that patients first presented with include hirsutism, acanthosis nigricans, androgenic alopecia, and skin tags. Oligomenorrhea was the most common systemic presenting sign. Statistical analysis of various clinical markers revealed correlations with hyperandrogenemia. Acanthosis nigricans and hirsutism were found to be useful clinical markers for hyperandrogenism, whereas androgenic alopecia was not. This study provides some insights into the presentation and diverse manifestations seen in hyperandrogenism. PMID:24933845

    Skills in reviewing medical charts have been demonstrated components of clinical competence related to knowledge base, level of clinical experience, and basic observational skills. A study of the generalizability of performance on chart review exercises, which controlled for knowledge in the content area, was undertaken to determine their potential in evaluating students' problem-solving ability. Results of the study indicate that the case specificity which has characterized simulated problem-solving tasks is largely case, rather than content, specificity: correlations between scores on single charts demonstrated no consistent relationships for measures of proficiency, efficiency, and diagnostic accuracy. However, averaging the scores on two charts and then computing correlations resulted in significant positive measures for both proficiency and efficiency. The effects of length and difficulty level on the generalizability of tests of problem-solving ability are areas suggested for future research.

    Full Text Available Abstract Background Studies have shown that early detection and treatment of neovascular age-related macular degeneration (NV-AMD can delay vision loss and blindness. The objective of this study was to evaluate the efficacy/safety of intravitreal pegaptanib sodium monotherapy in treatment-naïve subjects with newly diagnosed NV-AMD and to gain insight into characteristics of lesions treated in community-based practices. Methods From seven private US practices, charts were retrospectively reviewed on 73 subjects with previously untreated subfoveal choroidal NV-AMD treated with their first dose of pegaptanib monotherapy on/after 4/1/2005 through 6/5/2006, receiving ≥4 treatments at 6-week intervals over 21 weeks. Primary endpoint: mean visual acuity (VA change from baseline to month 6. Results 75% of lesions were occult, and 82% were subfoveal. From baseline to month 6, mean VA change was -0.68 lines; 58% and 16% gained ≥0 and ≥3 lines of VA, and 70% were responders ( Conclusion Pegaptanib is effective in real-world patients with treatment-naïve NV-AMD in uncontrolled community-based retina practices.

  9. Developing control charts to review and monitor medication errors.

    1992-03-01

    There is a need to monitor reported medication errors in a hospital setting. Because the quantity of errors vary due to external reporting, quantifying the data is extremely difficult. Typically, these errors are reviewed using classification systems that often have wide variations in the numbers per class per month. The authors recommend the use of control charts to review historical data and to monitor future data. The procedure they have adopted is a modification of schemes using absolute (i.e., positive) values of successive differences to estimate the standard deviation when only single incidence values are available in time rather than sample averages, and when many successive differences may be zero.

Despite guideline recommendations, sliding scale insulin remains commonplace in the LTC setting and data on basal insulin use are lacking.Methods: This retrospective study used medical chart data and the Minimum Data Set from elderly LTC facility patients who received basal insulin (insulin glargine, insulin detemir, or neutral protamine Hagedorn insulin for the treatment of diabetes, to investigate the practice patterns and associated clinical outcomes.Results: A total of 2,096 elderly, insulin-treated patients in LTC were identified, with 59.5% of them (N=1,247 receiving basal insulin. Of these, more than 50% of patients received sliding scale insulin in co-administration with basal insulin. Despite its ease of use, insulin pen use was very low, at 14.6%. Significant differences were observed between the basal insulin groups for glycated hemoglobin level and dosing frequency. Hypoglycemia was uncommon -17.2% of patients experienced at least one event, and there was no significant difference in the prevalence of hypoglycemia between the groups.Conclusion: These data suggest the underutilization of basal insulin in the LTC setting and worryingly high combinational use with sliding scale insulin. Differences in glycated hemoglobin and dosing frequencies between types of basal insulin warrant further comparative effectiveness studies.

    BACKGROUND: Professional organizations recommend car seat testing of preterm infants before discharge from hospital. Late preterm infants (LPIs, 340/7 to 366/7 weeks’ gestational age) are at the greatest risk for failure, despite often being well. OBJECTIVE: To determine the incidence of car seat testing failure in LPIs and associative factors. METHODS: A retrospective chart review was performed of inborn LPIs admitted to all levels of newborn care between July 1, 2012 and June 30, 2013. Data collected included maternal demographics, labour and delivery history, and neonatal course. Data were analyzed using backward logistic regression. RESULTS: A total of 511 charts were reviewed and 367 LPIs were eligible for inclusion. Of the 313 LPIs tested (mean [± SD] gestational age 36 weeks ±6 days and birth weight 2614±405 g), 80 (26%) failed (95% CI 21% to 31%). Most failed due to desaturations (≥2) of <88% for ≥10 s (n=33 [41%]). Multiple gestation was associated with failure (adjusted OR 2.45 [95% CI 1.44 to 4.18]; P=0.001), and there was a trend toward statistical significance for the variable postnatal age (0.996 [95% CI 0.99 to 1.00]; P=0.05). Infants who passed their car seat test had higher postnatal ages than those who failed (mean difference 39.4 h [95% CI 12.7 h to 66.0 h]; P=0.004). CONCLUSION: Twenty-six percent of LPIs failed car seat testing. Ideally, infants should be tested after an appropriate transitional period. The authors identified factors that may be important in designing future, prospective studies in this area. Future research should evaluate the clinical significance of car seat testing and resource utilization. PMID:26941555

    Increasing rates of obesity and heart disease are compromising quality of life for a growing number of people. There is much research linking adult disease with the growth and development both in utero and during the first year of life. The pig is an ideal model for studying the origins of developmental programming. The objective of this paper was to construct percentile growth curves for the pig for use in biomedical studies. The body weight (BW) of pigs was recorded from birth to 150 days of age and their crown-to-rump length was measured over the neonatal period to enable the ponderal index (PI; kg/m3) to be calculated. Data were normalised and percentile curves were constructed using Cole's lambda-mu-sigma (LMS) method for BW and PI. The construction of these percentile charts for use in biomedical research will allow a more detailed and precise tracking of growth and development of individual pigs under experimental conditions.

    Background Drug-related problems have been identified as a major contributor to emergency room visits, hospitalizations, and death. The most commonly implicated medications are nonsteroidal anti-inflammatory drugs (NSAIDs), antiplatelets, and anticoagulants. Considering a significant proportion of these harms are preventable, indicators to identify risky prescribing before they lead to harm have been developed. Objective To examine the prevalence and patterns of potentially inappropriate prescriptions (PIPs) in a primary care population who are using high-risk medications. Setting This study was performed within two multi-disciplinary family medicine teaching clinics in Winnipeg, Canada. Method A cross-sectional electronic/paper chart audit was conducted within two multi-disciplinary family medicine teaching clinics to evaluate the prevalence of 13 evidence-based high-risk prescriptions. Patients were included if they were prescribed an oral NSAID, antiplatelet, or an anticoagulant within the 12 month period between June 2012 and June 2013. Main outcome measure The proportion of PIPs associated with an increased bleeding risk for NSAIDs, antiplatelets, and anticoagulants. Results Of the 567 patients included in the review, 198 (35 %) patients had received at least 1 PIP in the past year. The most common PIP was the use of an oral NSAID with one or more GI risk factors without adequate gastro-protection. Only 34 (6 %) of these patients received a full medication review performed by a pharmacist. Although not statistically significant, patients who received a medication review had fewer inappropriate prescriptions (27 % with review, 35 % without). Conclusion Over one-third of the patients who were using high-risk medications were using them potentially inappropriately. Although pharmacists have been shown to reduce the amount of inappropriate prescribing, very few patients using these medications were referred to the pharmacist for a full medication review

    The primary aims of our study were to compare pregabalin and duloxetine in a neuromuscular clinic for diabetic neuropathic pain (DPN) and to study the effect of these medications in cryptogenic sensory polyneuropathy. We performed a retrospective chart review of 143 patients who were started on pregabalin or duloxetine during a 10-month period in a tertiary neuromuscular outpatient center for neuropathic pain. Duloxetine and pregabalin were started in 103 and 91 patients, respectively. Ninety-two patients tried only one of the two medications while both medications were used at different time periods in 51 patients. Follow-up was available for 87 patients on pregabalin and 89 patients on duloxetine. More patients with neuropathic pain reported an improvement with pregabalin (33%) than duloxetine (21%). Duloxetine (38%) had a higher frequency of side effects compared to pregabalin (30%). However, these differences between pregabalin and duloxetine were not statistically significant. Despite the study's limitations of retrospective design, these findings suggest that both pregabalin and duloxetine are probably effective for neuropathic pain, secondary to diabetes or cryptogenic sensory peripheral neuropathy in a tertiary care academic neuromuscular center. Prospective randomized controlled comparative effectiveness studies are required for both drugs in the treatment of neuropathic pain.

    Full Text Available Abstract Background The incidence and mortality from necrotizing fasciitis (NF are increasing in New Zealand (NZ. Triggered by a media report that traditional Samoan tattooing was causing NF, we conducted a chart review to investigate the role of this and other predisposing and precipitating factors and to document NF microbiology, complications and interventions in NZ. Methods We conducted a retrospective review of 299 hospital charts of patients discharged with NF diagnosis codes in eight hospitals in NZ between 2000 and 2006. We documented and compared by ethnicity the prevalence of predisposing and precipitating conditions, bacteria isolated, complications and interventions used. Results Out of 299 charts, 247 fulfilled the case definition. NF was most common in elderly males. Diabetes was the most frequent co-morbid condition, followed by obesity. Nearly a quarter of patients were taking non-steroidal anti-inflammatory drugs (NSAID. Traditional Samoan tattooing was an uncommon cause. Streptococcus pyogenes and Staphylococcus aureus were the two commonly isolated bacteria. Methicillin-resistant Staphylococcus aureus was implicated in a relatively small number of cases. Shock, renal failure, coagulation abnormality and multi-organ dysfunction were common complications. More than 90% of patients underwent surgical debridement, 56% were admitted to an intensive care unit (ICU and slightly less than half of all patients had blood product transfusion. One in six NF cases had amputations and 23.5% died. Conclusion This chart review found that the highest proportion of NF cases was elderly males with co-morbidities, particularly diabetes and obesity. Tattooing was an uncommon precipitating event. The role of NSAID needs further exploration. NF is a serious disease with severe complications, high case fatality and considerable use of health care resources.

    Background: Dermatology in vulnerable populations is under-researched. Our objective was to analyze the most commonly referred skin diseases affecting the Correctional Service Canada inmates in Ontario. Methods: An observational, cross-sectional, retrospective chart review of inmate patients seen from 2008 until 2013 was performed. Two groups of patients were included in the analysis: those assessed in-person, and those evaluated by e-consult. Results: In the in-person patient group, the 3 most common diagnoses were acne, psoriasis and other superficial mycoses. For the e-consult group, the 3 most frequent diagnoses were acne, psoriasis and rosacea. There was a clear bias toward more inmates being seen in-person where the service was provided (Collins Bay Institution) than from other correctional institutions in Eastern Ontario. Interpretation: Most of the skin diseases that affected the incarcerated population studied were common afflictions, similar to those affecting the general population, which is in agreement with other studies. Future studies investigating skin diseases in male and female inmates across Canada would bestow more generalizable data. PMID:27398381

Very few validated and reliable instruments exist for the assessment of quality of acute care in this field. This study's objective was to create such a tool for Geriatric Evaluation and Management Units (GEMUs. Methods The methodology involved a reliability and feasibility study of a retrospective chart review on 934 older inpatients admitted in 49 GEMUs during the year 2002–2003 for fall-related trauma as a tracer condition. Pertinent indicators for a chart abstraction tool, the Geriatric Care Tool (GCT, were developed and validated according to five dimensions: access to care, comprehensiveness, continuity of care, patient-centred care and appropriateness. Consensus methods were used to develop the content. Participants were experts representing eight main health care professions involved in GEMUs from 19 different sites. Items associated with high quality of care at each step of the multidisciplinary management of patients admitted due to falls were identified. The GCT was tested for intra- and inter-rater reliability using 30 medical charts reviewed by each of three independent and blinded trained nurses. Kappa and agreement measures between pairs of chart reviewers were computed on an item-by-item basis. Results Three quarters of 169 items identifying the process of care, from the case history to discharge planning, demonstrated good agreement (kappa greater than 0.40 and agreement over 70%. Indicators for the appropriateness of care showed less reliability. Conclusion Content validity and reliability results, as well as the feasibility of the process, suggest that the chart abstraction tool can gather standardized and pertinent clinical information for further evaluating quality of care in GEMU using admission due to falls as a tracer condition. However, the GCT

    Full Text Available This study examined whether patient-identified melanomas were more advanced than dermatologist-identified tumors at routine clinic visits, and whether a personal or family history of skin cancer was associated with patterns of detection. A retrospective chart review was performed on melanoma patients (N=201 in a private dermatology clinic. Variables included age, gender, pattern of detection (i.e., patient or a board certified dermatologist, personal or family history of skin cancer, skin type, and previous sun exposure, as well as tumor location and severity. Dermatologist-diagnosed melanomas were less invasive (P<0.0005, and more likely present on the chest, back, and legs (P<0.01. Conversely, patient-identified lesions were more likely to occur on the face, neck and scalp, be associated with younger patients, and a family history of melanoma, but not other types of skin cancer (P<0.01. In a post-hoc analysis examining these factors as predictors of tumor invasiveness, only diagnostic source was significant. Specifically, dermatologist-identified tumors were significantly less invasive than patient-identified tumors. Although age, family history, and tumor location played roles in the early detection of melanomas, the most important factor was diagnostic source. Thus, board-certified dermatologists play a key role in the early detection of malignant melanoma.

    Full Text Available Abstract Background Medical records that do not accurately reflect the patient’s current medication list are an open invitation to errors and may compromise patient safety. Methods This cross-sectional study compares primary care provider (PCP medication lists and pharmacy claims for 100 patients seen in 8 primary care practices and examines the association of congruence with demographic, clinical, and practice characteristics. Medication list congruence was measured as agreement of pharmacy claims with the entire PCP chart, including current medication list, visit notes, and correspondence sections. Results Congruence between pharmacy claims and the PCP chart was 65%. Congruence was associated with large chronic disease burden, frequent PCP visits, group practice, and patient age ≥45 years. Conclusion Agreement of medication lists between the PCP chart and pharmacy records is low. Medication documentation was more accurate among patients who have more chronic conditions, those who have frequent PCP visits, those whose practice has multiple providers, and those at least 45 years of age. Improved congruence among patients with multiple chronic conditions and in group practices may reflect more frequent visits and reviews by providers.

    Full Text Available BACKGROUND: Growth charts based on data collected in different populations and time periods are key tools to assess children's linear growth. We analyzed the impact of geographic factors and the secular trend on height-for-age charts currently used in European populations, developed up-to-date European growth charts, and studied the effect of using different charts in a sample of growth retarded children. METHODS AND FINDINGS: In an international survey we obtained 18 unique national height-for-age charts from 28 European countries and compared them with charts from the World Health Organization (WHO, Euro-Growth reference, and Centers of Disease Control and Prevention (CDC. As an example, we obtained height data from 3,534 children with end-stage renal disease (ESRD from 13 countries via the ESPN/ERA-EDTA registry, a patient group generally suffering from growth retardation. National growth charts showed a clear secular trend in height (mean height increased on average 0.6 cm/decade and a North-South height gradient in Europe. For countries without a recent (>1990 national growth chart novel European growth charts were constructed from Northern and Southern European reference populations, reflecting geographic height differences in mean final height of 3.9 cm in boys and 3.8 cm in girls. Mean height SDS of 2- to 17-year-old ESRD patients calculated from recent national or derived European growth charts (-1.91, 95% CI: -1.97 to -1.85 was significantly lower than when using CDC or WHO growth charts (-1.55, 95% CI: -1.61 to -1.49 (P<0.0001. CONCLUSION: Differences between height-for-age charts may reflect true population differences, but are also strongly affected by the secular trend in height. The choice of reference charts substantially affects the clinical decision whether a child is considered short-for-age. Therefore, we advocate using recent national or European height-for-age charts derived from recent national data when monitoring growth

    Full Text Available Abstract Background The purposes of this study are to document psychosocial stressors and medical conditions associated with development of insomnia in school-age children and to report use of hypnosis for this condition. Methods A retrospective chart review was performed for 84 children and adolescents with insomnia, excluding those with central or obstructive sleep apnea. All patients were offered and accepted instruction in self-hypnosis for treatment of insomnia, and for other symptoms if it was felt that these were amenable to therapy with hypnosis. Seventy-five patients returned for follow-up after the first hypnosis session. Their mean age was 12 years (range, 7–17. When insomnia did not resolve after the first instruction session, patients were offered the opportunity to use hypnosis to gain insight into the cause. Results Younger children were more likely to report that the insomnia was related to fears. Two or fewer hypnosis sessions were provided to 68% of the patients. Of the 70 patients reporting a delay in sleep onset of more than 30 minutes, 90% reported a reduction in sleep onset time following hypnosis. Of the 21 patients reporting nighttime awakenings more than once a week, 52% reported resolution of the awakenings and 38% reported improvement. Somatic complaints amenable to hypnosis were reported by 41%, including chest pain, dyspnea, functional abdominal pain, habit cough, headaches, and vocal cord dysfunction. Among these patients, 87% reported improvement or resolution of the somatic complaints following hypnosis. Conclusion Use of hypnosis appears to facilitate efficient therapy for insomnia in school-age children.

  11. Persistence and compliance to antidepressant treatment in patients with depression: A chart review

    2009-06-01

    Full Text Available Abstract Background Adherence has recently been suggested to be divided into these two components: persistence (i.e., whether patients continue treatment or not and compliance (i.e., whether patients take doses as instructed. However, no study has yet assessed these two clinically relevant components at the same time in adherence to antidepressant treatment in the clinical outpatient setting. Methods In this retrospective chart-review, 6-month adherence to antidepressants was examined in 367 outpatients with a major depressive disorder (ICD-10 (170 males; mean ± SD age 37.6 ± 13.9 years, who started antidepressant treatment from April 2006 through March 2007. Additionally, we evaluated Medication Possession Rate (MPR, defined as the total days a medication was dispensed to patients divided by the treatment period. Results Only 161 patients (44.3% continued antidepressant treatment for 6 months. Among 252 patients who discontinued their initial antidepressant, 63.1% of these patients did so without consulting their physicians. Sertraline use was associated with a higher persistence rate at month 6 (odds ratio 2.59 in comparison with sulpiride, and the use of anxiolytic benzodiazepines had a positive effect on persistence to antidepressant treatment only at month 1 (odds ratio 2.14. An overall MPR was 0.77; 55.6% of patients were considered compliant (i.e., a MPR of ≥ 0.8. Conclusion Given a high rate of antidepressant discontinuation without consulting their physicians, closer communication between patients and their physicians should be encouraged. Although the use of anxiolytic benzodiazepines was associated with a higher persistence to antidepressant treatment at month 1, the use of these drugs should be avoided as a rule, given their well-known serious adverse effects.

    Catherine G Sutcliffe

    Full Text Available BACKGROUND: Early infant HIV diagnosis is challenging in sub-Saharan Africa, particularly in rural areas where laboratory capacity is limited. Specimens must be transported to central laboratories for testing, leading to delays in diagnosis and initiation of antiretroviral therapy. This study was undertaken in rural Zambia to measure the turnaround time for confirmation of HIV infection and identify delays in diagnosis. METHODS: Chart reviews were conducted from 2010-2012 for children undergoing early infant HIV diagnosis at Macha Hospital in Zambia. Relevant dates, receipt of drugs by mother and child for the prevention of mother-to-child transmission (PMTCT, and test results were abstracted. RESULTS: 403 infants provided 476 samples for early infant diagnosis. The median age at the "6-week" and "6-month" assessments was 8.1 weeks and 7.0 months, respectively. The majority of mothers (80% and infants (67% received PMTCT. The median time between sample collection and arrival at the central laboratory in Lusaka was 17 days (IQR: 10, 28; arrival at the central laboratory to testing was 6 days (IQR: 5, 11; testing to return of results to the clinic was 29 days (IQR: 17, 36; arrival of results at the clinic to return of results to the caregiver was 45 days (IQR: 24, 79. The total median time from sample collection to return of results to the caregiver was 92 days (IQR: 84, 145. The proportion of HIV PCR positive samples was 12%. The total median turnaround time was shorter for HIV PCR positive as compared to negative or invalid samples (85 vs. 92 days; p = 0.08. CONCLUSIONS: Delays in processing and communicating test results were identified, particularly in returning results from the central laboratory to the clinic and from the clinic to the caregiver. A more efficient process is needed so that caregivers can be provided test results more rapidly, potentially resulting in earlier treatment initiation and better outcomes for HIV

    Full Text Available Background: Incidence and prevalence of non-communicable diseases, including ischaemic heart disease (IHD and associated acute myocardial infarction (AMI, are increasing in South Africa. Local studies are needed as contextual factors, such as healthcare systems, gender and ethnicity, may affect presentation and management. In AMI, reviews on time between onset of chest pain and initiation of urgent treatment are useful, as delays in initiation of thrombolytic treatment significantly increase morbidity and mortality.Aim: The aim of the study was to determine the profile and management of patients admitted with ischaemic chest pain.Setting: The study was carried out in a busy urban-based district hospital in KwaZulu-Natal, South Africa. The population served is poor, and patients are mainly Indian with associated high risk of IHD.Methods: A chart review of all patients seen at the hospital with acute ischaemic chest pain between 01 March and 31 August 2014 was undertaken.Results: More male than female patients were admitted, with a wide variation in age. Most eligible patients received required thrombolytic intervention within an acceptable time period after arrival at hospital.Conclusion: Chest pain and AMI were a relatively common presentation at the study site, and urgent diagnosis and initiation of fibrinolytic therapy are essential. The encouraging door-toneedle time may have been influenced by the availability of specialist family physicians, trained as ‘expert generalists’ to provide appropriate care in a variety of settings and consultant support to junior staff. The role of the family physician and primary healthcare doctor in primary prevention are re-emphasised through the study findings.Keywords: Acute myocardial infarction; KwaZulu-Natal; district hospital; Asian population; hospital chart review; door-to-needle-time

    2014-01-01

    Full Text Available Background. Delirium is a common and devastating condition which has been well characterized in elderly cancer patients, but little is known about delirium in cancer patients under the age of 65. Aim. A pilot study to explore the incidence and potential causes of delirium in hospitalized advanced cancer patients at the age of 18–56 years. Design. A retrospective chart review using validated instruments was used to examine the charts of hematology-oncology admissions in a large academic institution. Data was collected as to the likelihood of delirium and potential precipitants. Results. Delirium incidence was 29% among advanced cancer patients. The associated precipitants of delirium were multifactorial, the most common being medications and infection. Delirium was more common in patients admitted for either acute symptom management or the presence of a lung malignancy. Patients with delirium demonstrated significantly increased total hospital cost and a borderline significant result for increased mortality compared to those without delirium. Conclusions. Delirium is common in hospitalized advanced cancer patients (age 18–56 years and the cause is typically multifactorial. Delirium results in a more complicated hospital course and likely increased mortality. Further research is needed to define strategies to prevent and treat this common and distressing condition.

    2012-12-01

    Full Text Available We performed a retrospective chart review to examine the progress of patients with depression who received different frequencies of repetitive transcranial magnetic stimulation (rTMS delivered to the left dorsolateral prefrontal cortex (DLPFC. rTMS is a safe and effective alternative treatment for patients with various psychological and medical conditions. During treatment, a coil delivering a time-varying magnetic pulse placed over the scalp penetrates the skull, resulting in clinical improvement. There were 47 patients and three distinct treatment groups found: 10 Hz, 20 Hz, and a separate group who received both frequencies (10/20 Hz. The primary outcome indicator was the difference in Beck Depression Inventory–II (BDI-II scores. Secondary outcomes included categorical indicators of remission, response, and partial response rates as assessed with the BDI-II. In all 3 groups, the majority of patients had depression that remitted, with the highest rate occurring in the 20 Hz group. There were similar response rates in the 10 Hz and 20 Hz groups. There were no patients in the 10/20 Hz group whose depression responded and the highest partial response and nonresponse rates occurred in this group. Although within-group differences were significant from baseline to end of treatment, there were no between-group differences.

    To help the clinicians prescribe acupoints easily and effectively, we developed one simple flow chart to select acupoints. This study aimed to evaluate the usefulness of flow chart to select acupoints in dogs. Total 102 dogs showing intervertebral disc disease (IVDD) (n = 12), vomiting (n = 11), diarrhea (n = 2), abdominal pain (n = 5), cough (n = 66), or epilepsy (n = 6) received acupuncture treatment according to the chart, and its outcomes were evaluated as regards clinical symptoms, duration, treatment numbers, and recovery time. Dogs (8/8) with IVDD from grades I to III recovered over periods of 5 days to 6 weeks after 1-12 treatments, while 1/4 dogs with grade IV recovered over 7 weeks after 15 treatments. Vomiting dogs with acute/subacute (n = 8) and chronic symptoms (n = 3) required about 1 and 7 treatments to recover fully, respectively. All dogs (n = 5) with abdominal pain showed fast relief within 24 hours after acupuncture. Two diarrhea cases recovered over 2-9 days after 1-2 treatments. Fifty-four of 66 coughing dogs were recovered by 1-2 treatments. And 5 of 6 epilepsy dogs under a regular acupuncture treatment had no epileptic episode during followup of 12 months. These results suggest that this flow chart can help the clinicians prescribe acupoints effectively.

  1. Quality Assurance Peer Review Chart Rounds in 2011: A Survey of Academic Institutions in the United States

    International Nuclear Information System (INIS)

    Purpose: In light of concerns regarding the quality of radiation treatment delivery, we surveyed the practice of quality assurance peer review chart rounds at American academic institutions. Methods and Materials: An anonymous web-based survey was sent to the chief resident of each institution across the United States. Results: The response rate was 80% (57/71). The median amount of time spent per patient was 2.7 minutes (range, 0.6–14.4). The mean attendance by senior physicians and residents was 73% and 93%, respectively. A physicist was consistently present at peer review rounds in 66% of departments. There was a close association between attendance by senior physicians and departmental organization: in departments with protected time policies, good attendance was 81% vs. 31% without protected time (p = 0.001), and in departments that documented attendance, attending presence was 69% vs. 29% in departments without documentation (p 75% of institutions, whereas dosimetric details (beams, wedges), isodose coverage, intensity-modulated radiation therapy constraints, and dose–volume histograms were always peer reviewed in 63%, 59%, 42%, and 50% of cases, respectively. Chart rounds led to both minor (defined as a small multileaf collimator change/repeated port film) and major (change to dose prescription or replan with dosimetry) treatment changes. Whereas at the majority of institutions changes were rare (<10% of cases), 39% and 11% of institutions reported that minor and major changes, respectively, were made to more than 10% of cases. Conclusion: The implementation of peer review chart rounds seems inconsistent across American academic institutions. Brachytherapy and radiosurgical procedures are rarely reviewed. Attendance by senior physicians is variable, but it improves when scheduling clashes are avoided. The potential effect of a more thorough quality assurance peer review on patient outcomes is not known.

    2008-07-01

    Full Text Available Abstract Background Maintenance of therapeutic International Normalized Ratio (INR in the community is generally poor. The supervised environment in long-term care facilities may represent a more ideal setting for warfarin therapy since laboratory monitoring, compliance, dose adjustment, and interacting medications can all be monitored and controlled. The objectives of this study were to determine how effectively warfarin was administered to a cohort of residents in long-term care facilities, to identify the proportion of residents prescribed warfarin-interacting drugs and to ascertain factors associated with poor INR control. Methods A chart review of 105 residents receiving warfarin therapy in five long-term care facilities in Hamilton, Ontario was performed. Data were collected on INR levels, warfarin prescribing and monitoring practices, and use of interacting medications. Results Over a 12 month period (28,555 resident-days, 78.2 resident years 3065 INR values were available. Residents were within, below and above the therapeutic range 54%, 35% and 11% of the time, respectively. Seventy-nine percent of residents were prescribed at least one warfarin-interacting medication during the period in review. Residents receiving interacting medications spent less time in the therapeutic range (53.0% vs. 58.2%, OR = 0.93, 95% confidence interval 0.88 to 0.97, P = 0.002. Adequacy of anticoagulation varied significantly between physicians (time in therapeutic range 45.9 to 63.9%. Conclusion In this group of long-term care residents, warfarin control was suboptimal. Both prescriber and co-prescription of interacting medications were associated with poorer INR control. Future studies should seek strategies to improve prescriber skill and decrease use of interacting medications.

    Full Text Available Young children with fragile X syndrome (FXS often experience anxiety, irritability, and hyperactivity related to sensory hyperarousal. However, there are no medication recommendations with documented efficacy for children under 5 years old of age with FXS. We examined data through a chart review for 45 children with FXS, 12–50 months old, using the Mullen Scales of Early Learning (MSEL for baseline and longitudinal assessments. All children had clinical level of anxiety, language delays based on MSEL scores, and similar early learning composite (ELC scores at their first visit to our clinic. Incidence of autism spectrum disorder (ASD was similar in both groups. There were 11 children who were treated with sertraline, and these patients were retrospectively compared to 34 children who were not treated with sertraline by chart review. The baseline assessments were done at ages ranging from 18 to 44 months (mean 26.9, SD 7.99 and from 12 to 50 months (mean 29.94, SD 8.64 for treated and not treated groups, respectively. Mean rate of improvement in both expressive and receptive language development was significantly higher in the group who was treated with sertraline (<0.0001 and =0.0071, resp.. This data supports the need for a controlled trial of sertraline treatment in young children with FXS.

  8. A case study in Gantt charts as historiophoty: A century of psychology at the University of Alberta.

    Science.gov (United States)

    Dawson, Michael R W

    2013-05-01

    History is typically presented as historiography, where historians communicate via the written word. However, some historians have suggested alternative formats for communicating and thinking about historical information. One such format is known as historiophoty, which involves using a variety of visual images to represent history. The current article proposes that a particular type of graph, known as a Gantt chart, is well suited for conducting historiophoty. When used to represent history, Gantt charts provide a tremendous amount of information. Furthermore, the spatial nature of Gantt charts permits other kinds of spatial operations to be performed on them. This is illustrated with a case study of the history of a particular psychology department. The academic year 2009-2010 marked the centennial of psychology at the University of Alberta. This centennial was marked by compiling a list of its full-time faculty members for each year of its history. This historiography was converted into historiophoty by using it as the source for the creation of a Gantt chart. The current article shows how the history of psychology at the University of Alberta is revealed by examining this Gantt chart in a variety of different ways. This includes computing simple descriptive statistics from the chart, creating smaller versions of the Gantt to explore departmental demographics, and using image processing methods to provide measures of departmental stability throughout its history.

    Heterozygous loss-of-function (LOF) SMAD4 mutations are associated with juvenile polyposis syndrome (JP) and hereditary hemorrhagic telangiectasia (HHT). Some carriers exhibit symptoms of both conditions, leading to the name JP-HHT syndrome. Three families have been reported with connective tissue abnormalities. In order to better understand the spectrum and extent of clinical findings in SMAD4 carriers, medical records of 34 patients (20 families) from five clinical practices were reviewed. Twenty-one percent (7/34) had features suggesting a connective tissue defect: enlarged aortic root (n=3), aortic and mitral insufficiency (n=2), aortic dissection (n=1), retinal detachment (n=1), brain aneurysms (n=1), lax skin and joints (n=1). JP-specific findings were almost uniformly present but variable. Ninety-seven percent had colon polyps that were generally pan-colonic and of variable histology and number. Forty-eight percent (15/31) had extensive gastric polyposis. HHT features were documented in 76% including epistaxis (19/31, 61%), mucocutaneous telangiectases (15/31, 48%), liver arteriovenous malformation (AVM) (6/16, 38%), brain AVM (1/26, 4%), pulmonary AVM (9/17, 53%), and intrapulmonary shunting (14/23, 61%). SMAD4 carriers should be managed for JP and HHT, since symptoms of both are likely yet unpredictable. Connective tissue abnormalities are an emerging component of JP-HHT syndrome, and larger studies are needed to understand these manifestations. PMID:24525918

    Full Text Available Growth chart is the best measure for weight monitoring of children. Most factors that affect child heath show their effect on child weight. This cross sectional and descriptive analytical study was achieved to estimate malnutrition prevalence and effective factors in children under 5 years old in rural area of Khoramabad province. 555 girls and 570 boys were chosen from health houses by cluster sampling. Data were gathered through questionnaires. verbal interviews and child weighing. Nutritional status was estimated via weight/age index and the data were analysed by chi-square test. The results show 7.7% malnutrition among the children in this area. Factors that influence the nutritional status were: Frequency of diarrhea and acute respiratory infection, birth weight, duration of breast feeding and milk formula.

    Heterozygous loss-of-function SMAD4 mutations are associated with juvenile polyposis syndrome and hereditary hemorrhagic telangiectasia. Some carriers exhibit symptoms of both conditions, leading to juvenile polyposis-hereditary hemorrhagic telangiectasia syndrome. Three families have been reported with connective tissue abnormalities. To better understand the spectrum and extent of clinical findings in SMAD4 carriers, medical records of 34 patients (20 families) from five clinical practices were reviewed. Twenty-one percent of the patients (7/34) had features suggesting a connective tissue defect: enlarged aortic root (n = 3), aortic and mitral insufficiency (n = 2), aortic dissection (n = 1), retinal detachment (n = 1), brain aneurysms (n = 1), and lax skin and joints (n = 1). Juvenile polyposis-specific findings were almost uniformly present but variable. Ninety-seven percent of the patients had colon polyps that were generally pan-colonic and of variable histology and number. Forty-eight percent of the patients (15/31) had extensive gastric polyposis. Hereditary hemorrhagic telangiectasia features, including epistaxis (19/31, 61%), mucocutaneous telangiectases (15/31, 48%), liver arteriovenous malformation (6/16, 38%), brain arteriovenous malformation (1/26, 4%), pulmonary arteriovenous malformation (9/17, 53%), and intrapulmonary shunting (14/23, 61%), were documented in 76% of the patients. SMAD4 carriers should be managed for juvenile polyposis and hereditary hemorrhagic telangiectasia because symptoms of both conditions are likely yet unpredictable. Connective tissue abnormalities are an emerging component of juvenile polyposis-hereditary hemorrhagic telangiectasia syndrome, and larger studies are needed to understand these manifestations.

    Full Text Available Background and Objectives: Guidelines for bariatric surgery demand a psychological evaluation of applicants. The aim of this study was to evaluate if the presence of "psychological risk factors" predicts postoperative weight loss after gastric bypass. Methods: Medical records of obese women who underwent bariatric surgery between 2000 and 2004 were reviewed. Psychological assessment consisted of a one-hour semi-structured interview, summarized in a written report. Anthropometric assessment at baseline and 6,12,18 and 24 months after surgery included body weight, height and body mass index. Results: The mean BMI of included patients (N = 92 was 46.2 + 6,3 kg/m² (range 38.4 - 69.7. Based on the psychological assessment, 27% (N = 25 of the patients were classified as having "psychological risk factors" and 28% (N = 26 were diagnosed with a psychiatric diagnosis, most often major depression. Two years after gastric bypass, 16% of patients with "psychological risk factors" achieved an excellent result (%EWL > 75 versus 39% of those without (p < 0.05. About 1 out of 4 patients was in postoperative psychiatric treatment, but only half of them were identified as having "psychological risk factors" at baseline. Weight loss of patients initiating a psychiatric treatment only after surgery was less than of patients who continued psychiatric treatment already initiated before surgery (55.7 + 14.8 versus 66.5 + 14.2 %EWL. Conclusions: A single semi-structured psychological interview may identify patients who are at risk for diminished postoperative weight loss; however, psychological assessment did not identify those patients who were in need of a psychiatric postoperative treatment.

    2010-09-01

    Full Text Available Abstract Background Children with progressive metabolic, neurological, or chromosomal conditions and their families anticipate an unknown lifespan, endure unstable and often painful symptoms, and cope with erratic emotional and spiritual crises as the condition progresses along an uncertain trajectory towards death. Much is known about the genetics and pathophysiology of these diseases, but very little has been documented about the trajectory of symptoms for children with these conditions or the associated experience of their families. A longitudinal study design will help to close this gap in knowledge. Methods/Design Charting the Territory is a longitudinal descriptive, correlational study currently underway with children 0-19 years who are diagnosed with progressive neurological, metabolic, or chromosomal conditions and their families. The purpose of the study is to determine and document the clinical progression of the condition and the associated bio-psychosocial-spiritual experiences of the parents and siblings age 7-18 years. Approximately 300 families, both newly diagnosed children and those with established conditions, are being recruited in six Canadian cities. Children and their families are being followed for a minimum of 18 months, depending on when they enroll in the study. Family data collection will continue after the child's death if the child dies during the study period. Data collection includes monthly parental assessment of the child's symptoms; an annual functional assessment of the child; and completion of established instruments every 6 months by parents to assess family functioning, marital satisfaction, health status, anxiety, depression, stress, burden, grief, spirituality, and growth, and by siblings to assess coping and health. Impact of participation on parents is assessed after 1 year and at the end of the study. Chart reviews are conducted at enrollment and at the conclusion of the study or at the time of the

    Full Text Available Abstract Background Gut flora are important immunomodulators that may be disrupted in individuals with atopic conditions. Probiotic bacteria have been suggested as therapeutic modalities to mitigate or prevent food allergic manifestations. We wished to investigate whether perinatal factors known to disrupt gut flora increase the risk of IgE-mediated food allergies. Methods Birth records obtained from 192 healthy children and 99 children diagnosed with food allergies were reviewed retrospectively. Data pertaining to delivery method, perinatal antibiotic exposure, neonatal nursery environment, and maternal variables were recorded. Logistic regression analysis was used to assess the association between variables of interest and subsequent food allergy diagnosis. Results Retrospective investigation did not find perinatal antibiotics, NICU admission, or cesarean section to be associated with increased risk of food allergy diagnosis. However, associations between food allergy diagnosis and male gender (66 vs. 33; p=0.02 were apparent in this cohort. Additionally, increasing maternal age at delivery was significantly associated with food allergy diagnosis during childhood (OR, 1.05; 95% CI, 1.017 to 1.105; p=0.005. Conclusions Gut flora are potent immunomodulators, but their overall contribution to immune maturation remains to be elucidated. Additional understanding of the interplay between immunologic, genetic, and environmental factors underlying food allergy development need to be clarified before probiotic therapeutic interventions can routinely be recommended for prevention or mitigation of food allergies. Such interventions may be well-suited in male infants and in infants born to older mothers.

    Objective: Premature ejaculation is one of the most common forms of male sexual dysfunction. Recent clinical and genetic evidence suggests that it can be classified into 4 subtypes, which may have distinct clinical profiles. Psychological factors, such as anxiety, may play a specific role in the acquired subtype. The objective of this study was to assess the association between psychological factors, particularly anxiety and marital disharmony, and the various subtypes of premature ejaculation.

  5. The chart based approach to studying the global structure of a spacetime induces a coordinate invariant boundary

    CERN Document Server

    Whale, Ben

    2014-01-01

    I demonstrate that the chart based approach to the study of the global structure of Lorentzian manifolds induces a homeomorphism of the manifold into a topological space as an open dense set. The topological boundary of this homeomorphism is a chart independent boundary of ideal points equipped with a topological structure and a physically motivated classification. I show that this new boundary contains all other boundaries that can be presented as the topological boundary of an envelopment. Hence, in particular, it is a generalisation of Penrose's conformal boundary. I provide three detailed examples: the conformal compactification of Minkowski spacetime, Scott and Szekeres' analysis of the Curzon singularity and Beyer and Hennig's analysis of smooth Gowdy symmetric generalised Taub-NUT spacetimes.

    When regional geomagnetic charts for areas roughly the size of the US were compiled by hand, some large local anomalies were displayed in the isomagnetic lines. Since the late 1960s, when the compilation of charts using computers and mathematical models was started, most of the details available in the hand drawn regional charts have been lost. One exception to this is the Canadian magnetic declination chart for 1980. This chart was constructed using a 180 degrees spherical harmonic model. -from Author

  8. A comprehensive overview of medical error in hospitals using incident-reporting systems, patient complaints and chart review of inpatient deaths.

    Directory of Open Access Journals (Sweden)

    Jeantine M de Feijter

    Full Text Available BACKGROUND: Incident reporting systems (IRS are used to identify medical errors in order to learn from mistakes and improve patient safety in hospitals. However, IRS contain only a small fraction of occurring incidents. A more comprehensive overview of medical error in hospitals may be obtained by combining information from multiple sources. The WHO has developed the International Classification for Patient Safety (ICPS in order to enable comparison of incident reports from different sources and institutions. METHODS: The aim of this paper was to provide a more comprehensive overview of medical error in hospitals using a combination of different information sources. Incident reports collected from IRS, patient complaints and retrospective chart review in an academic acute care hospital were classified using the ICPS. The main outcome measures were distribution of incidents over the thirteen categories of the ICPS classifier "Incident type", described as odds ratios (OR and proportional similarity indices (PSI. RESULTS: A total of 1012 incidents resulted in 1282 classified items. Large differences between data from IRS and patient complaints (PSI = 0.32 and from IRS and retrospective chart review (PSI = 0.31 were mainly attributable to behaviour (OR = 6.08, clinical administration (OR = 5.14, clinical process (OR = 6.73 and resources (OR = 2.06. CONCLUSIONS: IRS do not capture all incidents in hospitals and should be combined with complementary information about diagnostic error and delayed treatment from patient complaints and retrospective chart review. Since incidents that are not recorded in IRS do not lead to remedial and preventive action in response to IRS reports, healthcare centres that have access to different incident detection methods should harness information from all sources to improve patient safety.

    2008-05-01

    Full Text Available Abstract Background To assess the intra- and inter-rater agreement of chart abstractors from multiple sites involved in the evaluation of an Asthma Care Program (ACP. Methods For intra-rater agreement, 110 charts randomly selected from 1,433 patients enrolled in the ACP across eight Ontario communities were re-abstracted by 10 abstractors. For inter-rater agreement, data abstractors reviewed a set of eight fictitious charts. Data abstraction involved information pertaining to six categories: physical assessment, asthma control, spirometry, asthma education, referral visits, and medication side effects. Percentage agreement and the kappa statistic (κ were used to measure agreement. Sensitivity and specificity estimates were calculated comparing results from all raters against the gold standard. Results Intra-rater re-abstraction yielded an overall kappa of 0.81. Kappa values for the chart abstraction categories were: physical assessment (κ 0.84, asthma control (κ 0.83, spirometry (κ 0.84, asthma education (κ 0.72, referral visits (κ 0.59 and medication side effects (κ 0.51. Inter-rater abstraction of the fictitious charts produced an overall kappa of 0.75, sensitivity of 0.91 and specificity of 0.89. Abstractors demonstrated agreement for physical assessment (κ 0.88, sensitivity and specificity 0.95, asthma control (κ 0.68, sensitivity 0.89, specificity 0.85, referral visits (κ 0.77, sensitivity 0.88, specificity 0.95, and asthma education (κ 0.49, sensitivity 0.87, specificity 0.77. Conclusion Though collected by multiple abstractors, the results show high sensitivity and specificity and substantial to excellent inter- and intra-rater agreement, assuring confidence in the use of chart abstraction for evaluating the ACP.

    1999-08-01

    Distance standards of height (growth charts) tend to get out of date and must be actualized from time to time. The aim of the present meta-analysis was to investigate characteristics of the cross sectional incremental pattern of body stature, evaluating the possibility of generating distance standards of height without the need for extensive de novo measurements. In view of the differences in growth in early and late childhood, we divided the total period of child development into the period between birth and the age of 6y, and between 6 and early adulthood (15y in females, 18 y in males). With respect to birth length, we meta-analysed 50 European and US American growth studies; with respect to growth in early childhood, 14 studies were analysed; and with respect to growth in late childhood, we meta-analysed 40 male and 51 female growth studies, from 14 European countries and the USA. Variations in body stature were meta-analysed in very large data samples, including the 1992 German birth cohort with more than 500 000 measurements of newborns, 10 000 measurements of 2-y-old German children, more than 500 000 measurements of German school children, and 6 large growth surveys of Japan and Czechoslovakia, with altogether more than 24 000 000 measurements. We found a rigid pattern of cross sectional body stature increment between birth and early adulthood that could be expressed by age-specific linear regression coefficients. Body stature was found to be related between sexes. Male birth length correlated with female length (r = 0.933, p < 0.001, slope = 4.62, intercept = 0.89), stature of 6-y-old boys correlated with stature of 6-y-old girls (r = 0.96, p < 0.001, slope = 1.05, intercept= -6.75), and stature of 18-y-old boys correlated with stature of 15-y-old girls (r=0.96, p < 0.001, slope = 0.90, intercept = 2.85). The developmental pace was also strongly related in both sexes. In conclusion, age-specific linear regression coefficients can be utilized synthetically

    We study systematically the properties of nuclei in the whole mass range up to the drip lines by the relativistic mean field (RMF) theory with deformations as a microscopic framework to provide the data of nuclear structure in the nuclear chart. The RMF theory is a phenomenological many-body framework, in which the self-consistent equations for nucleons and mesons are solved with arbitrary deformation, and has a potential ability to provide all the essential information of nuclear structure such as masses, radii and deformations together with single particle states and wave functions from the effective lagrangian containing nuclear interaction. As a first step toward the whole project, we study the ground state properties of even-even nuclei ranging from Z=8 to Z=120 up to the proton and neutron drip lines in the RMF theory. We adopt the parameter set TMA, which has been determined by the experimental masses and charge radii in a wide mass range, for the effective lagrangian of the RMF theory. We take into account the axially symmetric deformation using the constrained method on the quadrupole moment. We provide the properties of all even-even nuclei with all the possible ground state deformations extracted from the deformation energy curves by the constrained calculations. By studying the calculated ground state properties systematically, we aim to explore the general trend of masses, radii and deformations in the whole region of the nuclear chart. We discuss the agreement with experimental data and the predictions such as magicness and triaxial deformations beyond the experimental frontier. (author)

    Full Text Available The new method to chart the Hodges-Lehmann estimator control chart is proposed in this study. The evaluation of the three nonparametric control charts - the Sign test (ST, Mann-Whitney (MW, and the Hodges-Lehmann estimator (HL, for the known process distribution using normal and Weibull data represent the symmetric and asymmetric shapes of the process based on the original method through the 10000 run lengths simulation. The result illustrates that the average run length performance of the ST and MW correspond to their respective test statistics but for HL’s performance, the result indicates that the average run length is much greater than that derived from Wilcoxon signed rank statistics. The Hodges-Lehmann estimator control chart by the new approach for the known process distribution will be the alternative method for the process that needs to robust outliers’ properties from this statistics. In addition, the simulation demonstrates that the performances of the Sign test (ST from mean and median processes are varied in the skewed distribution, and moreover, the Sign test (ST from the median process represents more accurate performance. Meanwhile, for the control groups, MW generated within control limits or without restriction shows slightly different performance. The performance of dual scheme for the above-mentioned variable parameters control charts also produce the weighted average values that effect from the tight control scheme to the regular control scheme.

    For the first time, a generalized Smith chart is introduced here to represent fractional order circuit elements. It is shown that the standard Smith chart is a special case of the generalized fractional order Smith chart. With illustrations drawn for both the conventional integer based lumped elements and the fractional elements, a graphical technique supported by the analytical method is presented to plot impedances on the fractional Smith chart. The concept is then applied towards impedance matching networks, where the fractional approach proves to be much more versatile and results in a single element matching network for a complex load as compared to the two elements in the conventional approach. © 2010 IEEE.

    Ellis-van Creveld (EvC) syndrome is a congenital malformation syndrome with marked growth retardation. In this study, specific growth charts for EvC patients were derived to allow better follow-up of growth and earlier detection of growth patterns unusual for EvC. With the use of 235 observations of 101 EvC patients (49 males, 52 females), growth charts for males and females from 0 to 20 years of age were derived. Longitudinal and cross-sectional data were collected from an earlier review of growth data in EvC, a database of EvC patients, and from recent literature. To model the growth charts, the GAMLSS package for the R statistical program was used. Height of EvC patients was compared to healthy children using Dutch growth charts. Data are presented both on a scale for age and on a scale for the square root of age. Compared to healthy Dutch children, mean height standard deviation score values for male and female EvC patients were -3.1 and -3.0, respectively. The present growth charts should be useful in the follow-up of EvC patients. Most importantly, early detection of growth hormone deficiency, known to occur in EvC, will be facilitated.

    Kidney length is the most useful parameter for clinical measurement of kidney size, and is useful to distinguish acute kidney injury from chronic kidney disease. In this prospective observational study of 437 normal children aged between 0 and kidney length was measured using sonography. There were good correlations between kidney length and somatic values, including age, weight, height, and body surface area. The rapid growth of height during the first 2 years of life was intimately associated with a similar increase in kidney length, suggesting that height should be considered an important factor correlating with kidney length. Based on our findings, the following regression equation for the reference values of bilateral kidney length for Korean children was obtained: kidney length of the right kidney (cm) = 0.051 × height (cm) + 2.102; kidney length of the left kidney (cm) = 0.051 × height (cm) + 2.280. This equation may aid in the diagnosis of various kidney disorders. PMID:27366007

    A computer program translates Unified Modeling Language (UML) representations of state charts into source code in the C, C++, and Python computing languages. ( State charts signifies graphical descriptions of states and state transitions of a spacecraft or other complex system.) The UML representations constituting the input to this program are generated by using a UML-compliant graphical design program to draw the state charts. The generated source code is consistent with the "quantum programming" approach, which is so named because it involves discrete states and state transitions that have features in common with states and state transitions in quantum mechanics. Quantum programming enables efficient implementation of state charts, suitable for real-time embedded flight software. In addition to source code, the autocoder program generates a graphical-user-interface (GUI) program that, in turn, generates a display of state transitions in response to events triggered by the user. The GUI program is wrapped around, and can be used to exercise the state-chart behavior of, the generated source code. Once the expected state-chart behavior is confirmed, the generated source code can be augmented with a software interface to the rest of the software with which the source code is required to interact.

    Full Text Available Abstract Background Increasing appropriate use and documentation of caesarean section (CS has the potential to decrease maternal and perinatal mortality in settings with low CS rates. We analyzed data collected as part of a comprehensive needs assessment of emergency obstetric and newborn care (EmONC facilities in Afghanistan to gain a greater understanding of the clinical indications, timeliness, and outcomes of CS deliveries. Methods Records were reviewed at 78 government health facilities expected to function as EmONC providers that were located in secure areas of the country. Information was collected on the three most recent CS deliveries in the preceding 12 months at facilities with at least one CS delivery in the preceding three months. After excluding 16 facilities with no recent CS deliveries, the sample includes 173 CS deliveries at 62 facilities. Results No CS deliveries were performed in the previous three months at 21% of facilities surveyed; all of these were lower-level facilities. Most CS deliveries (88% were classified as emergencies, and only 12% were referrals from another facility. General anesthesia was used in 62% of cases, and spinal or epidural anesthesia in 34%. Only 28% of cases were managed with a partograph. Surgery began less than one hour after the decision for a CS delivery in just 30% of emergency cases. Among the 173 cases, 27 maternal deaths, 28 stillbirths, and 3 early neonatal deaths were documented. In cases of maternal and fetal death, the most common indications for CS delivery were placenta praevia or abruption and malpresentation. In 62% of maternal deaths, the fetus was stillborn or died shortly after birth. In 48% of stillbirths, the fetus had a normal heart rate at the last check. Information on partograph use was missing in 38% of cases, information on parity missing in 23% of cases and indications for cesareans missing in 9%. Conclusions Timely referral within and to EmONC facilities would decrease

  8. A gendered analysis of Canadian Aboriginal individuals admitted to inpatient substance abuse detoxification: a three-year medical chart review.

    This study examined gender differences within a sample of Canadian Aboriginal individuals admitted to an inpatient, hospital-based substance abuse detoxification program. Even though alcohol was the most frequent primary drug of detoxification for both genders, women received proportionately higher rates of cocaine or opiate detoxification diagnoses. In addition to a younger age, females reported higher rates of physical and sexual abuse. Women were also administered antidepressants, antibiotic medication protocols, and more medical evaluation tests. It appears that Canadian Aboriginal women have a diverse set of psychological and medical needs. This study demonstrates the need for detoxification programs to address the substantial rates of intravenous drug use and the associated risk of infectious disease (eg, Hepatitis C, HIV) among this treatment-seeking population.

Collected data included: visual acuity, central retinal thickness, intraocular pressure and history of glaucoma, wet AMD onset and treatment history, concomitant use of anticoagulants and past history or development of cerebrovascular or cardiovascular disease while receiving combination therapy. Results: Subjects underwent an average of five injections and two PDT treatments in total over 16 months before the choroidal neovascular membrane (CNVM stabilized and became inactive for at least 1 year. Prior to the effective anti-VEGF/PDT combination therapy the median Snellen visual acuity ranged from 20/200 to 20/250 and presented at no worse than 20/200 at 1 year after treatment. Some subjects were followed for up to 5 years and remained inactive.Conclusion: Combination therapy can cause long-lasting closure of the CNVM, even with advanced disease resistant to anti-VEGF monotherapy.

  12. INIS: Terminology charts

    International Nuclear Information System (INIS)

    This document is one in a series of publications known as the INIS Reference Series. It is to be used in conjunction with the INIS indexing manual and the INIS thesaurus for the preparation of input to the INIS database. The thesaurus and terminology charts in their first edition (Rev.0) were produced as the result of an agreement between the International Atomic Energy Agency (IAEA) and the European Atomic Energy Community (Euratom). Except for minor changes the terminology and the interrelationships between terms are those of the December 1969 edition of the Euratom Thesaurus. The purpose of the terminology harts is to display the descriptors of the thesaurus in the context of their hierarchical and other semantic relationships. Hierarchically related terms are grouped in clusters, each representing one of the principal concepts of a subject field. The descriptors are grouped around or under the broadest term of the clusters which is printed in upper case. The hierarchical relationships within the clusters are shown by the arrangement of the terms in smaller boxes within the larger boxes circumscribing the clusters. The clusters are connected by lines of various thickness, representing the other (mostly non-hierarchical) relationships. These connections are the equivalent to 'see also' and 'related term' cross-references. The thickness of the lines represents the strength of the semantic relations, or, in the practice of a retrieval system the probability that one term replacing a connected term in a query, will still yield pertinent references. The figures accompanying the descriptors represent their frequency of assignment to the first 987,000 documents stored in the Euratom system (May 1970). They are presented in order to show the relative importance of the descriptors within the subject field. The asterisks (*) accompanying descriptors in the charts refer to descriptors, for which a scope note can be found in the INIS: Thesaurus at the time the charts went

    Full Text Available There is an ongoing discussion on the rising CS rate worldwide. Suboptimal guideline adherence may be an important contributor to this rise. Before improvement of care can be established, optimal CS care in different settings has to be defined. This study aimed to develop and measure quality indicators to determine guideline adherence and identify target groups for improvement of care with direct effect on caesarean section (CS rates.Eighteen obstetricians and midwives participated in an expert panel for systematic CS quality indicator development according to the RAND-modified Delphi method. A multi-center study was performed and medical charts of 1024 women with a CS and a stratified and weighted randomly selected group of 1036 women with a vaginal delivery were analysed. Quality indicator frequency and adherence were scored in 2060 women with a CS or vaginal delivery.The expert panel developed 16 indicators on planned CS and 11 indicators on unplanned CS. Indicator adherence was calculated, defined as the number of women in a specific obstetrical situation in which care was performed as recommended in both planned and unplanned CS settings. The most frequently occurring obstetrical situations with low indicator adherence were: 1 suspected fetal distress (frequency 17%, adherence 46%, 2 non-progressive labour (frequency 12%, CS performed too early in over 75%, 3 continuous support during labour (frequency 88%, adherence 37% and 4 previous CS (frequency 12%, with adequate counselling in 15%.We identified four concrete target groups for improvement of obstetrical care, which can be used as a starting point to reduce CS rates worldwide.

    Although atypical antipsychotics are on the rise, traditional treatment of psychotic (or delusional) depression mostly includes the addition of classical antipsychotics to antidepressants. As there are only few data supporting this approach compared with antidepressant monotherapy, and almost no data comparing it with antidepressants of the latest generation, we conducted a retrospective chart analysis and a prospective, randomized open study on the efficacy and tolerability of nefazodone monotherapy versus combined treatment with amitriptyline and haloperidol in psychotic depression. The results suggest that the addition of classical antipsychotics should be reserved for those with very severe psychotic symptoms, but may not be needed in milder forms.

    Hwang, Moon Kyu; Kim, Hee Dong

    1999-03-01

    When a cold liquid is brought into contact with a molten material with a temperature significantly higher than the liquid boiling point, an explosive interaction due to sudden fragmentation of the melt and rapid evaporation of the liquid may take place. This phenomenon is referred to as a steam explosion or vapor explosion. Depending upon the amount of the melt and the liquid involved, the mechanical energy released during a vapor explosion can be large enough to cause serious destruction. In hypothetical severe accidents which involve fuel melt down, subsequent interactions between the molten fuel and coolant may cause steam explosion. This process has been studied by many investigators in an effort to assess the likelihood of containment failure which leads to large scale release of radioactive materials to the environment. In an effort to understand the phenomenology of steam explosion, extensive studies has been performed so far. The report presents both experimental and analytical studies on steam explosion. As for the experimental studies, both small scale tests which involve usually less than 20 g of high temperature melt and medium/large scale tests which more than 1 kg of melt is used are reviewed. For the modelling part of steam explosions, mechanistic modelling as well as thermodynamic modelling is reviewed. (author)

  20. A PIP chart for nuclear plant safety

    International Nuclear Information System (INIS)

    While it is known that social and political aspects of nuclear safety issues are important, little study has been done on identifying the breadth of stakeholders whose policies have important influences over nuclear plant safety in a comprehensive way. The objectives of this study are to develop a chart that visually identifies important stakeholders and their policies and illustrates these influences in a hierarchical representation so that the relationship between stakeholders and nuclear safety will be better understood. This study is based on a series of extensive interviews with major stakeholders, such as nuclear plant managers, corporate planning vice presidents, state regulators, news media, and public interest groups, and focuses on one US nuclear power plant. Based on the interview results, the authors developed a conceptual policy influence paths (PIP) chart. The PIP chart illustrates the hierarchy of influence among stakeholders. The PIP chart is also useful in identifying possible stakeholders who can be easily overlooked without the PIP chart. In addition, it shows that influence flow is circular rather than linear in one direction

    Contour interaction plays an important role in letter recognition and has long been known to influence clinical visual acuity measurements. LogMAR charts originally employed between-letter and line spacing of one letter width/height; however, in more recent designs, half letter width spacing has become accepted without validation. COMPlog is a computerised visual acuity measurement device being developed and validated for routine and research clinical use and is available commercially. This study was performed to investigate the effect of letter separation on computerised visual acuity measurements. An iterative series of experiments was performed in which test and retest fully interpolated five letters-per-line logMAR visual acuity measurements were taken in three groups of a total 100 adult subjects. Each group had visual acuity measured using ETDRS charts 1 and 2 and on COMPlog using various combinations of letter and line spacing. The first group consisted of 31 subjects tested using 3.75 and 2.50 stroke width spacing, the second 45 subjects using 2.50 and 1.25 stroke width spacing and the last group, 24 subjects tested using 1.90 stroke width spacing. The methods of Bland and Altman were used to analyse the data. No significant bias was noted between the gold standard ETDRS measurements and those taken using COMPlog with 3.75 stroke width spacing. Significant bias of half a logMAR line was found with crowding of 1.90 and 1.25 stroke widths. A small systematic bias with a reduction of 1 ETDRS letter was found with spacing of 2.50 stroke widths which has not been demonstrated in previous validation studies. Crowding of 2.50 stroke widths is the smallest spacing which can be used in the design of COMPlog.

    Time contour expression of limited range phenomena on stack chart is examined for further improvement on the result of the ultimate interpretation in the seismic reflection survey. The policy is made clear from the beginning that local phenomena are to be discussed, and data prior CMP stacking is interpreted in detail. For this purpose, it is effective to make use of the time contour expression in the midpoint-offset plane simultaneously with the CMP and COP panels. For the review of data prior to CMP stacking, it is convenient to use the CMP (CDP) stacking chart in which the data is arranged methodically. In this chart, all the channels which are crude data prior to stacking are plotted on midpoint-offset coordinates, which plane is called the MOD (Midpoint Offset Domain) panel. Various panels can be chosen unrestrictedly, and their mutual relations can be easily grasped. When data points are given a time axis, they can be expressed in a time contour. Studies are conducted about the underground structure, multiple reflection paths divided by it, and characteristics of detour reflection attributable to faults. 4 refs., 9 figs.

Critical Han Studies: The History, Representation, and Identity of China's Majority. Berkeley, Calif: University of California Press. This path-breaking volume is an academic collaboration that emerged out of the "Critical Han Studies Conference and Workshop" at Stanford University in April 2008. Eleven scholars contributed to the question of what it means to be 'Han' in China, both historically and at present. Constituting over ninety percent of China's population, the Han are not only the largest ethnic group in China, but are also one of the largest categories of collective identity in the world. Despite this, the dominant Han group has so far eluded careful scholarly scrutiny, with the Han often referred to as an unmarked majority category in contemporary China. This volume challenges such conventional views by conceptualizing new interdisciplinary approaches to the question of Hanness. The eleven essays of the volume are divided into three themes: 'Han and China', 'The Problem of Han Origins', and 'The Problem of Han Formations'. The first theme, comprised of four essays, analyzes the ties that bind the category of Han to those of Chinese ethnicity, race, and polity. Kevin Carrico in "Recentering China: The Cantonese in and Beyond the Han" questions a single, unitary Hanness that he believes conceals "countless other perceived and imagined lines of differentiation" (25.

    In a 2-part study, we first examined the results of 71 surveyed physicians who provided responses on how they address the management of patients who maintained either a pacemaker or a defibrillator during radiation treatment. Second, a case review study is presented involving 112 medical records reviewed at 18 institutions to determine whether there was a change in the radiation prescription for the treatment of the target cancer, the method of radiation delivery, or the method of radiation image acquisition. Statistics are provided to illustrate the level of administrative policy; the level of communication between radiation oncologists and heart specialists; American Joint Committee on Cancer (AJCC) staging and classification; National Comprehensive Cancer Network (NCCN) guidelines; tumor site; patient׳s sex; patient׳s age; device type; manufacturer; live monitoring; and the reported decisions for planning, delivery, and imaging. This survey revealed that 37% of patient treatments were considered for some sort of change in this regard, whereas 59% of patients were treated without regard to these alternatives when available. Only 3% of all patients were identified with an observable change in the functionality of the device or patient status in comparison with 96% of patients with normal behavior and operating devices. Documented changes in the patient׳s medical record included 1 device exhibiting failure at 0.3-Gy dose, 1 device exhibiting increased sensor rate during dose delivery, 1 patient having an irregular heartbeat leading to device reprogramming, and 1 patient complained of twinging in the chest wall that resulted in a respiratory arrest. Although policies and procedures should directly involve the qualified medical physicist for technical supervision, their sufficient involvement was typically not requested by most respondents. No treatment options were denied to any patient based on AJCC staging, classification, or NCCN practice standards.

    Full Text Available Rewards systems are one of the most significant issues of the human resource management. Throughout the literature, it is obvious that theorists and academics, as well as practitioners and managers emphasize the important factor of rewards. Additionally, job satisfaction is another crucial term within the same body of literature. Job satisfaction is likely to provide employees of all levels with feelings of fulfillment, achievement and even pleasure for their job. Thus, such feelings can make people more productive, creative and therefore more profitable for the organization. Furthermore, feelings of job satisfaction can strengthen the commitment and loyalty of employees with the organization, which is very necessary in present times where all firms are looking for competitive advantage and especially through their people. The objective of this study is to examine the correlation of the rewards systems and job satisfaction, based on a qualitative research. An attempt is also made to identify differences in rewards systems and the extent to which these differences influence job satisfaction among people in different organizational level.Qualitative evidence was found for the aspects of satisfaction in accordance with different kinds of rewards, focusing on the four hierarchical levels of an organization. One of the challenges of the study and its strength is the transitional stage that the organization is in, and the sub-cultures that have been created.Future research should measure crucial factors as behaviors, attitudes, performance and how these results can be linked to contextual elements and to employment performance.This study contributes to increase  job satisfaction awareness, which is important for organizational development .

    Full Text Available Abstract Background Electronic medical records contain valuable clinical information not readily available elsewhere. Accordingly, they hold important potential for contributing to and enhancing chronic disease registries with the goal of improving chronic disease management; however a standard for diagnoses of conditions such as diabetes remains to be developed. The purpose of this study was to establish a validated electronic medical record definition for diabetes. Methods We constructed a retrospective cohort using health administrative data from the Institute for Clinical Evaluative Sciences Ontario Diabetes Database linked with electronic medical records from the Deliver Primary Healthcare Information Project using data from 1 April 2006 - 31 March 2008 (N = 19,443. We systematically examined eight definitions for diabetes diagnosis, both established and proposed. Results The definition that identified the highest number of patients with diabetes (N = 2,180 while limiting to those with the highest probability of having diabetes was: individuals with ≥2 abnormal plasma glucose tests, or diabetes on the problem list, or insulin prescription, or ≥2 oral anti-diabetic agents, or HbA1c ≥6.5%. Compared to the Ontario Diabetes Database, this definition identified 13% more patients while maintaining good sensitivity (75% and specificity (98%. Conclusions This study establishes the feasibility of developing an electronic medical record standard definition of diabetes and validates an algorithm for use in this context. While the algorithm may need to be tailored to fit available data in different electronic medical records, it contributes to the establishment of validated disease registries with the goal of enhancing research, and enabling quality improvement in clinical care and patient self-management.

  18. A paediatric X-ray exposure chart

    International Nuclear Information System (INIS)

    The aim of this review was to develop a radiographic optimisation strategy to make use of digital radiography (DR) and needle phosphor computerised radiography (CR) detectors, in order to lower radiation dose and improve image quality for paediatrics. This review was based on evidence-based practice, of which a component was a review of the relevant literature. The resulting exposure chart was developed with two distinct groups of exposure optimisation strategies – body exposures (for head, trunk, humerus, femur) and distal extremity exposures (elbow to finger, knee to toe). Exposure variables manipulated included kilovoltage peak (kVp), target detector exposure and milli-ampere-seconds (mAs), automatic exposure control (AEC), additional beam filtration, and use of antiscatter grid. Mean dose area product (DAP) reductions of up to 83% for anterior–posterior (AP)/posterior–anterior (PA) abdomen projections were recorded postoptimisation due to manipulation of multiple-exposure variables. For body exposures, the target EI and detector exposure, and thus the required mAs were typically 20% less postoptimisation. Image quality for some distal extremity exposures was improved by lowering kVp and increasing mAs around constant entrance skin dose. It is recommended that purchasing digital X-ray equipment with high detective quantum efficiency detectors, and then optimising the exposure chart for use with these detectors is of high importance for sites performing paediatric imaging. Multiple-exposure variables may need to be manipulated to achieve optimal outcomes

Purpose: The Ministry of Health of Sri Lanka has recommended World Health Organization/International Society of Hypertension (WHO/ISH charts for cardiac risk assessment in individuals with T2DM. However, the most suitable cardiac risk assessment tool for Sri Lankans with T2DM has not been studied. This study was designed to evaluate the performance of two cardiac risk assessments tools; WHO/ISH charts and UK Prospective Diabetes Study (UKPDS risk engine. Methods: Cardiac risk assessments were done in 2,432 patients with T2DM attending a diabetes clinic in Southern Sri Lanka using the two risk assessment tools. Validity of two assessment tools was further assessed by their ability to recognize individuals with raised low-density lipoprotein (LDL and raised diastolic blood pressure in a cohort of newly diagnosed T2DM patients (n=332. Results: WHO/ISH charts identified 78.4% of subjects as low cardiac risk whereas the UKPDS risk engine categorized 52.3% as low cardiac risk (P<0.001. In the risk categories of 10%–<20%, the UKPDS risk engine identified higher proportions of patients (28% compared to WHO/ISH charts (7%. Approximately 6% of subjects were classified as low cardiac risk (<10% by WHO/ISH when UKPDS recognized them as cardiac risk of >20%. Agreement between the two tools was poor (κ value =0.144, P<0.01. Approximately 82% of individuals categorized as low cardiac risk by WHO/ISH had higher LDL cholesterol than the therapeutic target of 100 mg/dL. Conclusion: There is a significant discrepancy between the two assessment tools with WHO/ISH risk chart recognizing higher proportions of patients

    Full Text Available Statistical quality control techniques are useful in monitoring the process behaviour. Attribute control charts are widely used in process control. The selection of sample size, sampling interval and control width of the control chart is important in minimising the quality costs. Control chart parameters, like 3delta controlimits and fixed fraction sampling at conveniently selected sampling intervals result in deplovable cost penalties in quality control. The best selection of these parameters depends on several process parameters,like frequency of occupancy of a shift in the process, cost of sampling, cost of investigation for finding assignable cause, probability of false alarms, penalty cost of defectives and process correction cost. A general model has been developed to determine the total quality cost as a function of these parameters. Probability of not identifying a process shift (Beeta-risk and probability of wrongly. concluding the process got shifted (alpha-risk are considered in developing the model. This cost equation is optimised to determine optimum values control chart parameters. Fibonacci search is used to quicken the analytical method or determining optimum sampling size and control width. The proposals made by Duncan, Montgomery, Gibra and Chiu for determining the optimum control chart parameters are critically examined and compared with the present model. Case studies were conducted in two foundries. Optimum control chart parameters in casting of cylinder liners and cast plates are determined. It has been found that quality costs are considerably reduced by using optimally designed control chart parameters with proposed method.

    For assessing tactile spatial resolution it has recently been recommended to use tactile acuity charts which follow the design principles of the Snellen letter charts for visual acuity and involve active touch. However, it is currently unknown whether acuity thresholds obtained with this newly developed psychophysical procedure are in accordance with established measures of tactile acuity that involve passive contact with fixed duration and control of contact force. Here we directly compared tactile acuity thresholds obtained with the acuity charts to traditional two-point and grating orientation thresholds in a group of young healthy adults. For this purpose, two types of charts, using either Braille-like dot patterns or embossed Landolt rings with different orientations, were adapted from previous studies. Measurements with the two types of charts were equivalent, but generally more reliable with the dot pattern chart. A comparison with the two-point and grating orientation task data showed that the test-retest reliability of the acuity chart measurements after one week was superior to that of the passive methods. Individual thresholds obtained with the acuity charts agreed reasonably with the grating orientation threshold, but less so with the two-point threshold that yielded relatively distinct acuity estimates compared to the other methods. This potentially considerable amount of mismatch between different measures of tactile acuity suggests that tactile spatial resolution is a complex entity that should ideally be measured with different methods in parallel. The simple test procedure and high reliability of the acuity charts makes them a promising complement and alternative to the traditional two-point and grating orientation thresholds.

    Purpose: To evaluate the applicability of different visual acu-ity charts for outpatient pediatric visual tests. Methods: Fifty-three children (53 eyes) aged 4-8 years un-dergoing visual acuity tests as outpatients were randomly se-lected for this study. The best corrected visual acuity (BCVA) of the eye with better visual acuity was measured for each child using the digital LogMAR visual chart,.the ETDRS vi-sual chart,.and a new standard logarithm visual chart;.all measurements were repeated twice and the BCVA was record-ed. Paired comparisons were made between the LogMAR vi-sual acuity chart and ETDRS chart measurements or between the ETDRS chart and logarithm visual acuity chart measure-ments for statistical analysis of the differences in measurement of visual acuity..The results of different measurements by the same chart were compared to evaluate the consistency of the measurement results..Bland-Altman analysis was employed to evaluate the most suitable chart for outpatient measurement of visual acuity in children. Results:.Bland-Altman analysis revealed that the mean visual acuity measured was. (0.447 ±0.017 LogMAR).by the digital LogMAR chart,.(0.301±0.024 LogMAR).by the standard log-arithm visual acuity chart, and (0.309 ±0.018 LogMAR) by the ETDRS visual acuity chart. The BCVA was significantly lower when measured by the LogMAR visual acuity chart than by the ETDRS chart (P0.05)..The Bland-Altman plot showed that the high-est consistency was obtained with the digital LogMAR chart, with a difference between two repeated measurements of 0.068 LogMAR,.compared to 0.090 and 0.072 LogMAR for the logarithm and ETDRS visual acuity charts, respectively. Conclusion: All three types of visual acuity charts are appli-cable for outpatient measurement of pediatric visual acuity. The ETDRS and logarithm visual acuity charts have a higher consistency, but the LogMAR visual acuity chart shows better reproducibility..Consequently,.it is difficult to identify and

    Full Text Available Abstract Background The Accreditation Council on Graduate Medical Education (ACGME supports chart audit as a method to track competency in Practice-Based Learning and Improvement. We examined whether peer chart audits performed by internal medicine residents were associated with improved documentation of foot care in patients with diabetes mellitus. Methods A retrospective electronic chart review was performed on 347 patients with diabetes mellitus cared for by internal medicine residents in a university-based continuity clinic from May 2003 to September 2004. Residents abstracted information pertaining to documentation of foot examinations (neurological, vascular, and skin from the charts of patients followed by their physician peers. No formal feedback or education was provided. Results Significant improvement in the documentation of foot exams was observed over the course of the study. The percentage of patients receiving neurological, vascular, and skin exams increased by 20% (from 13% to 33% (p = 0.001, 26% (from 45% to 71% (p Conclusion Peer chart audits performed by residents in the absence of formal feedback were associated with improved documentation of the foot exam in patients with diabetes mellitus. Although this study suggests that peer chart audits may be an effective tool to improve practice-based learning and documentation of foot care in diabetic patients, evaluating the actual performance of clinical care was beyond the scope of this study and would be better addressed by a randomized controlled trial.

    Pan Li

    Full Text Available BACKGROUND: Numerous clinical trials have demonstrated that elderly patients with colorectal cancer (CRC can benefit from chemotherapy, yet compliance in real-world practice is low. The purpose of this study is to investigate the efficacy, compliance and reasons for refusal of postoperative chemotherapy for elderly patients with CRC and to provide corresponding strategies. PATIENTS AND METHODS: The clinico-pathological and biochemical data of the chemotherapy group and chemo-refusing group were compared among 386 elderly patients (>70 years old with CRC who underwent surgery. 226 patients received chemotherapy and 160 patients refused. Follow-up of the subjective reasons for refusal was investigated using the elderly caner patients' chemo-refusal reason questionnaire (ECPCRRQ prepared by the authors and a group of psychologists. The questionnaire is administrated by telephone. A predictive model for 5-year disease-free survival (DFS and 5-year overall survival (OS was constructed by using Kaplan-Meier analysis, logistic and Cox regression. RESULTS: Among stage III patients, receiving chemotherapy was associated with a significantly higher OS (68% compared to those who refused ( OS 50% (HR: 2.05, 95%CI: 1.12-3.77, P = 0.02. The Chemo-refusal group had more female and elderly patients, significantly higher rate of severe complications, and lower body mass index (BMI. Follow-up phone questionnaire analysis showed the doctors' uncertainty of chemotherapy benefit, economic difficulties, uncomfortable feeling, superstition of Traditional Chinese Medicine, concealing information and lack of social support were the main factors for elderly CRC patients to decline chemotherapy. CONCLUSION: The receipt of post-operative chemotherapy in elderly patients with resected stage III CRC was associated with a more favorable survival. The low compliance rate (160/386 of postoperative chemotherapy was influenced by various subjective and objective factors.

    2013-08-01

    Full Text Available Generalised cumulative count of conforming (GCCC charts have been proposed for monitoring a high-yield process that allows the items to be inspected sample by sample and not according to the production order. Recent study has shown that the GCCC chart with a variable sampling interval (VSI is superior to the traditional one with a fixed sampling interval (FSI because of the additional flexibility of sampling interval it offers. However, the VSI chart is still costly when used for the prevention of defective products. This paper presents an economic model for the design problem of the VSI GCCC chart, taking into account the correlation of the production outputs within the same sample. In the economic design, a cost function is developed that includes the cost of sampling and inspection, the cost of false alarms, the cost of detecting and removing the assignable cause, and the cost when the process is out-of-control. An evolutionary search method using the cost function is presented for finding the optimal design parameters of the VSI GCCC chart. Comparisons between VSI and FSI charts for expected cost per unit time are also made for various process and cost parameters.

  15. Continuity Adjustment for Control Charts for Attributes

    L.K. Chan; T.K. Mak; B. Tao

    2003-01-01

    A unified approach is proposed for making a continuity adjustment on some control charts for attributes, e.g., np-chart and c-chart, through adding a uniform (0, 1) random observation to the conventional sample statistic (e.g., npi and ci). The adjusted sample statistic then has a continuous distribution. Consequently, given any Type I risk α (the probability that the sample statistic is on or beyond the control limits),control charts achieving the exact value of α can be readily constructed. Guidelines are given for when to use the continuity adjustment control chart, the conventional Shewhart control chart (with ±3 standard deviations control limits), and the control chart based on the exact distribution of the sample statistic before adjustment.

  16. Pearl A Probabilistic Chart Parser

    CERN Document Server

    Magerman, D M; Magerman, David M.; Marcus, Mitchell P.

    1994-01-01

    This paper describes a natural language parsing algorithm for unrestricted text which uses a probability-based scoring function to select the "best" parse of a sentence. The parser, Pearl, is a time-asynchronous bottom-up chart parser with Earley-type top-down prediction which pursues the highest-scoring theory in the chart, where the score of a theory represents the extent to which the context of the sentence predicts that interpretation. This parser differs from previous attempts at stochastic parsers in that it uses a richer form of conditional probabilities based on context to predict likelihood. Pearl also provides a framework for incorporating the results of previous work in part-of-speech assignment, unknown word models, and other probabilistic models of linguistic features into one parsing tool, interleaving these techniques instead of using the traditional pipeline architecture. In preliminary tests, Pearl has been successful at resolving part-of-speech and word (in speech processing) ambiguity, dete...

The proposed KM-chart gives the minimum closed spherical boundary around the in-control process data. It measures the distance between the center of KMDD-based sphere and the new incoming sample to be monitored. Any sample having a distance greater than the radius of KMDD-based sphere is considered as an out-of-control sample. Phase I and II analysis of KM-chart was evaluated through a real industrial application. In a comparative study based on the average run length (ARL criterion, KM-chart was compared with the kernel-distance based control chart, referred to as K-chart, and the k-nearest neighbor data description-based control chart, referred to as KNN-chart. Results revealed that, in terms of ARL, KM-chart performed better than KNN-chart in detecting small shifts in mean vector. Furthermore, the paper provides the MATLAB code for KM-chart, developed by the authors.

    为了解决现有顺序功能图无法灵活地表达自动循环与手动操作之间的工作状态转换问题,以液压动力滑台典型工作步骤为研究对象,提出了增设状态变量并插入微小分支回路的方法来保存两种状态之间的动态存储器变化过程。研究表明:重新设计后的顺序功能图与梯形图之间呈现出了更为严格的映射关系。通过图论建模发现,模型重构后连通图的最大流数量比之前有所增加,但是仍然符合图的封闭性原则,从而维持了控制系统的稳定性。通过现场观察梯形图的运行过程,控制程序在两种状态之间实现了断点无扰动切换,验证了新算法的正确性与可靠性。%In order to solve the problem that the current sequential function chart cannot express the conversion between automatic circulation and manual operation flexibly,taking the example of the typical work steps of hy-draulic power sliding table as the research object,the paper brings forward a method by adding state variables and inserting some micro branches to hold the change process of dynamic memory between these two states.The se-quential function chart and ladder diagram shows a more rigorous mapping relationship after redesign.By means of graph theory model establishment,we can find that the number of maximum flow has been increased than before after model reconstruction,but it still meets the needs of closure principle of graph,so as to maintain the stability of the control system.Through the observation of running the ladder diagram on the spot,the control program can shift between these two states with non-disturbance at the breakpoint,verifying the correctness and reliability of the new algorithm.

    Full Text Available Abstract Background Current model of medication supply to R(RACFs in Australia is dependent on paper-based prescriptions. This study is aimed at assessing the use of a centralized medication chart as a prescription-less model for supplying medications to RACFs. Methods Two separate focus groups were conducted with general practitioners (GPs and pharmacists, and another three with registered nurses (RNs and carers combined. All focus group participants were working with RACFs. Audio-recorded data were compared with field notes, transcribed and imported into NVivo® where it was thematically analyzed. Results A prescription-less medication chart model was supported and it appeared to potentially improve medication supply to RACF residents. Centralization of medication supply, clarification of medication orders and responding in real-time to therapy changes made by GPs were reasons for supporting the medication chart model. Pharmacists preferred an electronic version of this model. All health professionals cautioned against the need for GPs regularly reviewing the medication chart and proposed a time interval of four to six months for this review to occur. Therapy changes during weekends appeared a potential difficulty for RNs and carers whereas pharmacists cautioned about legible writing and claiming of medications dispensed according to a paper-based model. GPs cautioned on the need to monitor the amount of medications dispensed by the pharmacy. Conclusion The current use of paper prescriptions in nursing homes was identified as burdensome. A prescription-less medication chart model was suggested to potentially improve medication supply to RACF residents. An electronic version of this model could address main potential difficulties raised.

    Full Text Available Civil aviation is developing rapidly, and the number of domestic and international operations is increasing exponentially every year than the previous one. Airline companies with increased air traffic and the number of passengers increase the demand of new aircrafts. An aircraft needs not only fuel but also pilot and aeronautical information (charts, digital navigation information, flight plan, and etc. to perform flight operation. One of the most important components in aeronautical information is the terminal chart. Authorized institution in every state is responsible to publish their terminal charts for certain periods. Although these charts are produced in accordance with ICAO’s Annex 4 and Annex 15, cartographic representation and page layout differs in each state’s publication. This situation makes difficult to read them by pilots. In this paper, standard instrument departure (SID charts are analysed to produce by use of cutting-edge and competitive technologies instead of classical computer-aided drawing and vector based graphic applications that are currently used by main chart producers. The goal is to design efficient and commercial chart management system that is able to produce aeronautical charts with same cartographic representation for all states.

  12. A video strip chart program

    International Nuclear Information System (INIS)

    A strip chart recorder has been utilized for trend analysis of the Oak Ridge National Laboratory EN tandem since 1987. At the EN, the author could not afford the nice eight channel thermal pen recorder that was used at the 25 URC. He had to suffice with two channel fiber tip or capillary pen type recorders retrieved from salvage and maintained with parts from other salvaged recorders. After cycling through several machines that eventually became completely unserviceable, a search for a new thermal recorder was begun. As much as he hates to write computer code, he decided to try his hand at getting an old data acquisition unit, that had been retrieved several years ago from salvage, to meet his needs. A BASIC language compiler was used because time was not available to learn a more advanced language. While attempting to increase acquisition and scroll speed on the 6 MHz 80286 that the code was first developed on, it became apparent that scrolling only the first small portion of the screen at high speed and then averaging that region and histogramming the average provided both the speed necessary for capturing fairly short duration events, and a trend record without use of back scrolling and disk storage routines. This turned out to be quite sufficient

  14. A Nonparametric Shewhart-Type Quality Control Chart for Monitoring Broad Changes in a Process Distribution

    Directory of Open Access Journals (Sweden)

    Saad T. Bakir

    2012-01-01

    Full Text Available This paper develops a distribution-free (or nonparametric Shewhart-type statistical quality control chart for detecting a broad change in the probability distribution of a process. The proposed chart is designed for grouped observations, and it requires the availability of a reference (or training sample of observations taken when the process was operating in-control. The charting statistic is a modified version of the two-sample Kolmogorov-Smirnov test statistic that allows the exact calculation of the conditional average run length using the binomial distribution. Unlike the traditional distribution-based control charts (such as the Shewhart X-Bar, the proposed chart maintains the same control limits and the in-control average run length over the class of all (symmetric or asymmetric continuous probability distributions. The proposed chart aims at monitoring a broad, rather than a one-parameter, change in a process distribution. Simulation studies show that the chart is more robust against increased skewness and/or outliers in the process output. Further, the proposed chart is shown to be more efficient than the Shewhart X-Bar chart when the underlying process distribution has tails heavier than those of the normal distribution.

    1999-04-01

    The task of this review study is to from provide an overview of the developments in the field of the various advanced nuclear systems, and to create the basis for more comprehensive studies of technology assessment. In an overview the concepts for advanced nuclear systems pursued worldwide are subdivided into eight subgroups. A coarse examination raster (set pattern) is developed to enable a detailed examination of the selected systems. In addition to a focus on enhanced safety features, further aspects are also taken into consideration, like the lowering of the proliferation risk, the enhancement of the economic competitiveness of the facilities and new usage possibilities (for instance concerning the relaxation of the waste disposal problem or the usage of alternative fuels to uranium). The question about the expected time span for realization and the discussion about the obstacles on the way to a commercially usable reactor also play a substantial role as well as disposal requirements as far as they can be presently recognized. In the central chapter of this study, the documentation of the representatively selected concepts is evaluated as well as existing technology assessment studies and expert opinions. In a few cases where this appears to be necessary, according technical literature, further policy advisory reports, expert statements as well as other relevant sources are taken into account. Contradictions, different assessments and dissents in the literature as well as a few unsettled questions are thus indicated. The potential of advanced nuclear systems with respect to economical and societal as well as environmental objectives cannot exclusively be measured by the corresponding intrinsic or in comparison remarkable technical improvements. The acceptability of novel or improved systems in nuclear technology will have to be judged by their convincing solutions for the crucial questions of safety, nuclear waste and risk of proliferation of nuclear weapons

  16. Live sequence charts to model medical information

    2012-06-01

    Full Text Available Abstract Background Medical records accumulate data concerning patient health and the natural history of disease progression. However, methods to mine information systematically in a form other than an electronic health record are not yet available. The purpose of this study was to develop an object modeling technique as a first step towards a formal database of medical records. Method Live Sequence Charts (LSC were used to formalize the narrative text obtained during a patient interview. LSCs utilize a visual scenario-based programming language to build object models. LSC extends the classical language of UML message sequence charts (MSC, predominantly through addition of modalities and providing executable semantics. Inter-object scenarios were defined to specify natural history event interactions and different scenarios in the narrative text. Result A simulated medical record was specified into LSC formalism by translating the text into an object model that comprised a set of entities and events. The entities described the participating components (i.e., doctor, patient and record and the events described the interactions between elements. A conceptual model is presented to illustrate the approach. An object model was generated from data extracted from an actual new patient interview, where the individual was eventually diagnosed as suffering from Chronic Fatigue Syndrome (CFS. This yielded a preliminary formal designated vocabulary for CFS development that provided a basis for future formalism of these records. Conclusions Translation of medical records into object models created the basis for a formal database of the patient narrative that temporally depicts the events preceding disease, the diagnosis and treatment approach. The LSCs object model of the medical narrative provided an intuitive, visual representation of the natural history of the patient’s disease.

    Full Text Available The aim of this study is to analyze the use of a binomial cumulative sum chart (CUSUM to monitor the presence of total coliforms, biological indicators of quality of water supplies in water treatment processes. The sample series were monthly taken from a water treatment plant and were analyzed from 2007 to 2009. The statistical treatment of the data was performed using GNU R, and routines were created for the approximation of the upper limit of the binomial CUSUM chart. Furthermore, a comparative study was conducted to investigate whether there is a significant difference in sensitivity between the use of CUSUM and the traditional Shewhart chart, the most commonly used chart in process monitoring. The results obtained demonstrate that this study was essential for making the right choice in selecting a chart for the statistical analysis of this process.

    We investigate astronomical materials listed in the book of Bibliographie Coréenne written by Maurice Courant. He classified ancient Korean books into nine Divisions (?) and thirty six Classes (?), and published them as three volumes (ranging from 1894 to 1896) and one supplement (in 1901). In total, 3,821 books including astronomical ones are listed together with information on physical size, possessional place, bibliographical note, and so forth. Although this book is an essential one in the field of Korea bibliography and contains many astronomical materials such as Cheon-Mun-Ryu-Cho ????, Si-Heon-Seo ??????, and Cheon-Sang-Yeol-Cha-Bun-Ya-Ji-Do ????????, it has not been well known to the public nor to astronomical society. Of 3,821 catalogues, we found that about 50 Items (?) are related to astronomy or astrology, and verified that most ! of them are located in the Kyujanggak Royal Library ???. We also found an unknown astronomical chart, Hon-Cheon-Chong-Seong-Yeol-Cha-Bun-Ya-Ji-Do ??????????. Because those astronomical materials are not well known to international astronomical community and there have been few studies on the materials in Korea, we here introduce and review them, particularly with the astronomical viewpoint.

    It is generally accepted that appropriate documentation of activities and recommendations of ethics consultants in patients' medical records is critical. Despite this acceptance, the bioethics literature is largely devoid of guidance on key elements of an ethics chart note, the degree of specificity that it should contain, and its stylistic tenor. We aim to provide guidance for a variety of persons engaged in clinical ethics consultation: new and seasoned ethics committee members who are new to ethics consultation, students and trainees in clinical ethics, and those who have significant experience with ethics consultation so that they can reflect on their practice. Toward the goal of promoting quality charting practices in ethics consultations, we propose recommendations on a broad array of questions concerning clinical ethics consultation chart notes, including whether and when to write a chart note, and practical considerations for the tenor, purpose, and content of a chart note. Our broader aim is to promote discussion about good charting practices in clinical ethics, with the hope of contributing to clear standards of excellence in clinical ethics consultation.

    2014-09-01

    In the past several years a vast amount of digital information has become available in every field of science, and ideas to apply improved strategies for obtaining a more in-depth knowledge of the data are considered in many areas. Although several American and European organizations show regularly in their public websites the aggregated results of organ donation and transplantation, no tools are provided to engage with the final users and to enable them to handle these data. In this study, a new model of Web-based interactive motion charts was applied to aggregated liver transplantation data obtained from a consecutive 28-year series of liver transplantation performed in a single Italian center. The interactive charts were obtained by combining the Google visualization application programming interface and the googleVis package within the open source statistical environment R. The interactive charts may be embedded into online/offline Web pages and rendered in each common browser. The users may interact with the charts by selecting chart type (bubble, bar, or line chart), x- and y-axis scales (linear or logarithmic), variables, bubble size, color, and even changing opacity of unselected items. Moreover, the charts may dynamically display the trend over time of each continuous/categoric variable, allowing users both to trace how the lines changes over time and to control the animation speed. The interactive motion charts should be used in the public websites that manage aggregated data concerning organ donation and transplantation. PMID:25242769

    INTRODUCTION Run charts are quality improvement tools. AIM To investigate the feasibility and acceptability of run charts displaying weekly cardiovascular disease (CVD) risk assessments in general practice and assess their impact on CVD risk assessments. METHODS A controlled non-randomised observational study in nine practices using run charts and nine control practices. We measured the weekly proportion of eligible patients with completed CVD risk assessments for 19 weeks before and after run charts were introduced into intervention practices. A random coefficients model determined changes in CVD risk assessment rates (slope) from pre- to post- intervention by aggregating and comparing intervention and control practices' mean slopes. We interviewed staff in intervention practices about their use of run charts. RESULTS Seven intervention practices used their run chart; six consistently plotting weekly data for >12 weeks and positioning charts in a highly visible place. Staff reported that charts were easy to use, a visual reminder for ongoing team efforts, and useful for measuring progress. There were no significant differences between study groups: the mean difference in pre- to post-run chart slope in the intervention group was 0.03% more CVD risk assessments per week; for the control group the mean difference was 0.07%. The between group difference was 0.04% per week (95% CI: -0.26 to 0.35, P = 0.77). DISCUSSION Run charts are feasible in everyday general practice and support team processes. There were no differences in CVD risk assessment between the two groups, likely due to national targets driving performance at the time of the study. PMID:27477560

    International Nuclear Information System (INIS)

    This chart is for frequent use in the prediction of the product species of neutron activation. The first edition of the chart has been made in 1976 after the repeated trial preparation. It has the following good points. (1) Any letter in chart is as large as one can read easily. [This condition has been obtained by the selection of items to be shown in chart. They are the name (the symbol of element, mass number, and half-life) of nuclide or of isomer, and the type of decay.]. (2) Decay product has been shown indirectly for branchings with two-step decay via short-lived daughter in an excited state. [This matter has been realized by use of the new mode of indication.] (3) Nuclides shown in chart are (a) naturally occurring nuclides and (b) nuclides formed from naturally occurring nuclides through one of the following reactions: (n, γ), (n, n'), (n, p), (n, α), (n, 2n), (n, pn), (n, 3n), (n, αn), (n, t), (n, 3He), (n, 2p), and (n, γ)(n, γ). In the revision of the first edition, some modes of indication have become a little simpler, and the isomers of shorter half-lives (0.1 - 1 μs) have been added. (author)

    2010-03-01

    Full Text Available Abstract Background Screening and early diagnosis has been shown to reduce the morbidity and mortality associated with certain conditions such as cervical cancer. The role of general practitioners in promoting primary prevention of diseases is particularly important given that they have frequent contact with a large proportion of the population. This study assessed the extent to which general practitioners documented recommended preventive screening interventions among eligible patients. Methods We used a retrospective chart audit to assess patient visits to primary care clinics in Calgary, Canada from 2002-2004. We included fee for service physicians who practiced ≥ 2 days per week at their current location and excluded those whose primary practice was at walk-in clinics, community health centers, hospitals or emergency rooms. We included charts of patients who during the study period were age 35 years or older and had at least 2 visits to a clinic. We randomly selected and reviewed charts (N = 600 from 12 primary care clinics and abstracted information on 6 conditions recommended for preventive screening. Opportunities for preventive screening were determined based on recommendations of the Canadian Task Force on Preventive Health Care, the American College of Physicians, and the Canadian Cancer Society. Our main outcome measures included cancer screening (mammography and pap smears, immunization (influenza and pneumococcal, and risk factor assessment (cholesterol measurement and smoking cessation consultation. Results Patient visits to GP clinics present opportunities for preventive screening. However, we found that documentation of interventions was low, ranging from 40.3% (cholesterol measurement to 0.9% (pneumococcal vaccination within 1 year, and from 67.4% to 1.8% within the prior 3 years. Conclusions Documentation of preventive screening interventions by general practitioners was relatively low compared to the number of patients

    2003-12-01

    The turn of the 21st century marks the onset of a renaissance in the field of infrasound, which had been dormant for ~30 years. The ongoing deployment of a global infrasound network has reawakened the field to a world of high-resolution digital array data, rapid communication, and seemingly unlimited growth in computing power. Complex phenomena that could only be addressed in general terms three decades ago can now be measured, analyzed, and modeled with unprecedented fidelity. Many fundamental problems in infrasound are now being revisited, and infrasonic observations are being integrated with other technologies (such as seismic, strainmeter and infrared) for the discovery of new phenomena or the refinement of geophysical studies. On July 24-25, 2003, the National Science Foundation sponsored a group of infrasound experts and interdisciplinary researchers to convene in Waikoloa, Hawaii, and chart a course for basic US infrasound research. The conveners selected key projects that would lead to significant advances in our understanding of infrasound generated by effusive and explosive volcanoes, ocean swells, bolides, fauna, severe weather, and long-period atmospheric instabilities. Projects were also proposed to refine our knowledge of atmospheric dynamics and transport mechanisms. A sampling of these projects is discussed in light of their contributions to our fundamental scientific understanding and their impact on the geophysical community.

    2015-01-01

    European singles charts are important part of the music industry responsible for creating popularity of songs. After modeling and exploring dynamics of global album sales in previous papers, we investigate patterns of hit singles popularity according to all data (1966-2015) from weekly charts (polls) in 12 Western European countries. The dynamics of building popularity in various national charts is more than the economy because it depends on spread of information. In our research we have shown how countries may be affected by their neighbourhood and influenced by technological era. We have also computed correlations with geographical and cultural distances between countries in analog, digital and Internet era. We have shown that time delay between the single premiere and the peak of popularity has become shorter under the influence of technology and the popularity of songs depends on geographical distances in analog (1966-1987) and Internet (2004-2015) era. On the other hand, cultural distances between nation...

    Andres, E; Temme, M; Raderschatt, B; Szecsenyi, J; Sandholzer, H; Kochen, M M

    1995-01-01

    BACKGROUND: Functional status is considered an important measure of health status in primary care. The COOP-WONCA charts, which comprise six single-item scales, have mainly been used to determine functional ability in chronically ill patients. AIM: A study was carried out to determine whether the charts are able to measure the degree of functional impairment associated with acute illness and the improvement in functional ability accompanying the process of recovery. METHOD: A total of 95 patients presenting with acute low back pain were recruited from 15 single-handed general practices in northern Germany. At presentation and at two-week follow up, these patients completed self-administered questionnaires which included the COOP-WONCA charts. The charts ask patients to use the timescale of the past two weeks when rating their condition. Baseline and follow-up measurements of the charts were compared and correlations of chart scores with patients' measurements of pain intensity on a visual analogue scale, general practitioners' ratings of impairment and patients' measurements of recovery were analysed. RESULTS: Only the chart measuring change in health revealed a deterioration in functional ability associated with the onset of pain and an improvement in functional status at follow up. Two of the other charts indicated a deterioration at follow up. Only the chart measuring change in health was correlated with ratings of pain and impairment at baseline. At follow up, strong correlations were found between general practitioners' assessments of impairment, patients' ratings of pain and patients' ratings of recovery for all scales except for those measuring social activities and daily activities. The patients interpreted the instructions for using the COOP-WONCA charts differently; some included the period of acute back pain while others did not. CONCLUSION: Of the six charts only the change in health chart proved to be a suitable scale for measuring short-term changes

    Mobile technology is increasingly used to measure visual acuity. Standards for chart-based acuity tests specify photometric requirements for luminance, optotype contrast and luminance uniformity. Manufacturers provide some photometric data but little is known about tablet performance for visual acuity testing. This study photometrically characterised seven tablet computers (iPad, Apple inc.) and three ETDRS (Early Treatment Diabetic Retinopathy Study) visual acuity charts with room lights on and off, and compared findings with visual acuity measurement standards. Tablet screen luminance and contrast were measured using nine points across a black and white checkerboard test screen at five arbitrary brightness levels. ETDRS optotypes and adjacent white background luminance and contrast were measured. All seven tablets (room lights off) exceeded the most stringent requirement for mean luminance (≥ 120 cd/m2) providing the nominal brightness setting was above 50%. All exceeded contrast requirement (Weber ≥ 90%) regardless of brightness setting, and five were marginally below the required luminance uniformity threshold (Lmin/Lmax ≥ 80%). Re-assessing three tablets with room lights on made little difference to mean luminance or contrast, and improved luminance uniformity to exceed the threshold. The three EDTRS charts (room lights off) had adequate mean luminance (≥ 120 cd/m2) and Weber contrast (≥ 90%), but all three charts failed to meet the luminance uniformity standard (Lmin/Lmax ≥ 80%). Two charts were operating beyond manufacturer's recommended lamp replacement schedule. With room lights on, chart mean luminance and Weber contrast increased, but two charts still had inadequate luminance uniformity. Tablet computers showed less inter-device variability, higher contrast, and better luminance uniformity than charts in both lights-on and lights-off environments, providing brightness setting was >50%. Overall, iPad tablets matched or marginally out

    2011-01-01

    Full Text Available Abstract: Problem statement: Almost all of the modern biomedical equipments that record the biopotential actions have digital output but the paper chart records are a must. The volume of these records is significant and increasing rapidly. Keeping a bio-signal chart of a patient make it easy for quick assessment but still create problems in the essence of data storage, archiving , data interchange and communications. Approach: A solution to all these problems is to convert these paper records to digital form. In this study, a method for bio-potential signal extraction from single or multi-channel paper recorded charts using image processing techniques is developed. Results: After scanning the paper charts and converting them into images using a commercial scanner, the developed algorithm applied to eliminate the background of the scanned paper chart from any recording device single channel or multi-channel using binary neighborhood morphological operations then converting the extracted waveform image into quantized values representing the waveform recorded paper chart. The extracted signal then filtered to remove the high frequency effects that result from the morphological operations. A correlation and frequency analysis procedure then conducted to verify the result against known sampled waveform. Conclusion: A chart paper conversion to digital values that represent only the values for the biopotential waveform and eliminating the other irrelevant information has been achieved. These resulted in a less space occupation of patient records and make it easy for data further processing and manipulations."

    Kaiser, Peter K.

    2009-01-01

    Purpose: The purpose of this study was twofold: first, to prospectively compare visual acuity (VA) scores obtained with Snellen charts versus Early Treatment Diabetic Retinopathy Study (ETDRS) charts in a “real world” retinal practice, and second, to see if there was a difference in visual acuity measurements obtained with ETDRS charts starting at 4 or 2 meters. Methods: Prospective, consecutive evaluation of patients who underwent best-corrected visual acuity testing of their right eye performed at a single seating by the same experienced, certified vision examiner in the same room with standardized low light conditions using a projected Snellen chart at 20 feet, and two different back-illuminated ETDRS charts placed 4 and 2 meters from the patient. Results: One hundred sixty-three eyes were included in the study. The mean Snellen VA was 0.67 logMAR (20/94), ETDRS VA at 4 meters was 0.54 logMAR (~20/69), and ETDRS VA at 2 meters was 0.51 logMAR (~20/65). The mean difference was 6.5 letters better on the ETDRS chart (P=.000000001). As the VA worsened, there was increased variability between the charts and the mean discrepancy between charts also increased. Subgroup analysis revealed the greatest difference between charts was in the poor vision subgroup (<20/200) with a difference of 0.2 logMAR (10 letters; P=.0000002). Patients with exudative age-related macular degeneration (AMD) had the greatest disparity on vision testing, but patients with dry AMD and diabetic retinopathy also exhibited significant differences. Conclusions: Visual acuity scores were significantly better on ETDRS charts compared to Snellen charts. The difference was greatest with poor visual acuity (<20/200) and in patients with exudative AMD. Thus, caution should be exercised when comparing data using the different charts. PMID:20126505

  11. Performance of Statistical Control Charts with Bilateral Limits of Probability to Monitor Processes Weibull in Maintenance

    Directory of Open Access Journals (Sweden)

    Quintana Alicia Esther

    2015-01-01

    Full Text Available Manufacturing with optimal quality standards is underpinned to the high reliability of its equipment and systems, among other essential pillars. Maintenance Engineering is responsible for planning control and continuous improvement of its critical equipment by any approach, such as Six Sigma. This is nourished by numerous statistical tools highlighting, among them, statistical process control charts. While their first applications were in production, other designs have emerged to adapt to new needs as monitoring equipment and systems in the manufacturing environment. The time between failures usually fits an exponential or Weibull model. The t chart and adjusted t chart, with probabilistic control limits, are suitable alternatives to monitor the mean time between failures. Unfortunately, it is difficult to find publications of them applied to the models Weibull, very useful in contexts such as maintenance. In addition, literature limits the study of their performance to the analysis of the standard metric average run length, thus giving a partial view. The aim of this paper is to explore the performance of the t chart and adjusted t chart using three metrics, two unconventional. To do this, it incorporates the concept of lateral variability, in their forms left and right variability. Major precisions of the behavior of these charts allow to understand the conditions under which are suitable: if the main objective of monitoring lies in detecting deterioration, the t chart with adjustment is recommended. On the other hand, when the priority is to detect improvements, the t chart without adjustment is the best choice. However, the response speed of both charts is very variable from run to run.

  12. Observing rapid quasi-wave ionospheric disturbance using amplitude charts

    Science.gov (United States)

    Kurkin, Vladimir; Laryunin, Oleg; Podlesnyi, Alexey

    Data from vertical (quasi-vertical) sounding are traditionally used for determining a number of ionospheric parameters such as critical frequencies of E and F layers, peaks of these layers, and for reconstructing electron density profiles. In this respect, radio sounding is not used to its full capacity. Modern ionosondes provide additional information encoded in ionospheric echoes, including information on reflected-signal amplitude. The time dependence of the amplitude-frequency characteristic of reflected signal has been named "amplitude chart" (A-chart). Ionosondes used by the ISTP SB RAS Geophysical Observatory for constructing A-charts employ the frequency-modulated continuous-wave (FMCW) signal in a range 1.3-15 MHz. One-minute sounding interval allows a more detailed study of dynamic processes in the ionosphere. The ionosonde has a direct digital synthesizer and direct sampling receiver without automatic gain control (AGC). The absence of AGC and the high dynamic range enable determination of the relative field strength at a receiving point and registration of relative long-term variations in reflected-signal amplitude over the entire range of operating frequencies of the ionosonde. We have revealed that the passage of travelling ionospheric disturbances (TID) along with height-frequency distortion modulates amplitude characteristics of signal. The characteristic depth of the modulation reaches 40 dB. The pronounced alternate vertical stripes typical for A-charts are likely to be associated with focusing properties of TID. In order to examine the space-time structure of TID able to induce such a focusing of the radio waves, we performed ray tracing simulations. We used geometrical-optics approximation, took magneto-ionic effects into account and prescribed electron density to be a stratified electron density profile on which an undulating disturbance was superimposed. This work was supported by the RFBR grant №14-05-00259-а.

    In this paper, a statistical procedure to construct a control chart for monitoring air quality (PM10) using functional data is proposed. A set of daily indices that represent the daily PM10 curves were obtained using Functional Principal Component Analysis (FPCA). By means of an iterative charting procedure, a reference data set that represented a stable PM10 process was obtained. The data were then used as a reference for monitoring future data. The application of the procedure was conducted using seven-year (2004-2010) period of recorded data from the Klang air quality monitoring station located in the Klang Valley region of Peninsular Malaysia. The study showed that the control chart provided a useful visualization tool for monitoring air quality and was capable in detecting abnormality in the process system. As in the case of Klang station, the results showed that with reference to 2004-2008, the air quality (PM10) in 2010 was better than that in 2009.

    'Indian' numerals, which are popular among the Arab population, were used to devise a new Snellen's visual acuity chart. The new chart has the advantages of a reading chart. It keeps the patient's interest, does not miss alexic patients, and is quicker to perform. It is also devoid of the many disadvantages of a kinetic response chart (the capital E letter or Landolt's broken rings), especially that of the limited option of test objects.

    Full Text Available The purpose of this study is to propose an approach to fuse multiscale charts into three-dimensional (3D electronic navigational chart (ENC systems based on underwater topography and remote sensing image. This is the first time that the fusion of multiscale standard ENCs in the 3D ENC system has been studied. First, a view-dependent visualization technology is presented for the determination of the display condition of a chart. Second, a map sheet processing method is described for dealing with the map sheet splice problem. A process order called “3D order” is designed to adapt to the characteristics of the chart. A map sheet clipping process is described to deal with the overlap between the adjacent map sheets. And our strategy for map sheet splice is proposed. Third, the rendering method for ENC objects in the 3D ENC system is introduced. Fourth, our picking-up method for ENC objects is proposed. Finally, we implement the above methods in our system: automotive intelligent chart (AIC 3D electronic chart display and information systems (ECDIS. And our method can handle the fusion problem well.

    The major concern on the management of superheated liquids, in industrial environments, is the large potential hazards involved in cases of any accidental release. There is a possibility that a violent phase change could take place inside the fluid released generating a flashing jet. This violent phase change might produce catastrophic consequences, such as explosions, fires or toxic exposure, in the installations and in the surroundings. The knowledge and understanding of the mechanisms involved in those releases become an important issue in the prevention of these consequences and the minimization of their impact. This work presents a comprehensive review of information about flashing processes. The review begins with a description of the single phase jet followed by a description of the two-phase flashing jet. The concepts and implications of the thermodynamic and mechanical effects on the behaviour of the jets are considered at the beginning of the review. Following the review is devoted to the classification of the different study approaches used to understand flashing processes in the past, highlighting various critical parameters on the behaviour and the hazard consequences of flashing jets. The review also contains an extensive compilation of experimental, theoretical and numerical data relating to these phenomena, which includes information on the distinct characteristics of the jet, since type of jet, velocity distribution, expansion angle and mass phase change all require individual estimation.

    This paper aimed to review currently available cohort studies of subjects with mood disorders such as major depressive disorder (MDD) and bipolar disorder (BD). Using the PubMed and KoreaMed databases, we reviewed eight major cohort studies. Most studies recruited participants with MDD and BD separately, so direct comparison of factors associated with diagnostic changes was difficult. Regular and frequent follow-up evaluations utilizing objective mood ratings and standardized evaluation methods in a naturalistic fashion are necessary to determine detailed clinical courses of mood disorders. Further, biological samples should also be collected to incorporate clinical findings in the development of new diagnostic and therapeutic approaches. An innovative cohort study that can serve as a platform for translational research for treatment and prevention of mood disorders is critical in determining clinical, psychosocial, neurobiological and genetic factors associated with long-term courses and consequences of mood disorders in Korean patients.

    Full Text Available Purpose: To compare visual acuity with two visual acuity charts in preschool children. Materials and Methods: Visual acuity measurement with Lea symbols and Bailey-Lovie tumbling E chart was performed on children between 3 and 6 years of age. Visual acuity data from the two charts were analyzed with Bland-Altman plot to determine the limits of agreement. The Wilcoxon signed test was performed in children aged 3-4 years and in children aged 5-6 years separately to evaluate the influence of age. The inter-eye difference between the two charts were further analyzed with the paired t-test. A p value < 0.05 was considered statistically significant. Results: A total of 47 children were enrolled for the study. The average logarithm of the Minimum Angle of Resolution (LogMAR monocular visual acuity with Lea symbols (0.17 ± 0.13 was better than the Bailey-Lovie tumbling E chart (0.22 ± 0.14. The mean difference between Bailey-Lovie tumbling E chart and Lea symbol chart was 0.05 ± 0.12 in logMAR units. A second analysis eliminating outliers showed the same result but lower differences (n = 43, 0.05 ± 0.05 logMAR units. Visual acuity results between the two charts in children aged 3-4 years showed a significant difference (p = 0.000, but not for children aged 5-6 years (p = 0.059. Inter-eye differences between the two charts was not statistically significant (p = 0.77. Conclusion: Bailey-Lovie tumbling E chart is comparable to the Lea symbols chart in pre-school children. But preference should be given to Lea symbols for children aged 3-4 years as the symbols are more familiar than a directional test for this age group.

    Full Text Available This study aimed to investigate the articles which entreated misconceptions in mathematics education from 1999 to 2013 in Turkey in a thematic frame. In order to reach this aim, survey method which is one of the descriptive research methods was adopted for this study. Within the scope of the study, 45 articles published between stated years in Turkish language and accessed through the relevant databases consisted the sample of the study. The articles accessed were analyzed by using categorical analysis technique in the context of sample/study group, topic, education level, publication year, misconception determination technique. Findings revealed that although there is an observable increase in the number of studies related to the misconceptions recently, those studies are mostly about determining the misconceptions and the number of the studies about removing the misconceptions is limited. According to the results of the present study, it can be suggested that studies should be carried out using different and multiple techniques to remove the misconceptions along with the studies determining them. Furthermore, in addition to the multiple choice questions which have been used quite often in order to determine the misconceptions in mathematics education, the techniques such as concept map, semantic analysis chart, prediction-observation-explanation, etc. are considered to be helpful for in-depth examination of the misconceptions.Keywords: Mathematics education, misconception studies, thematic review.

    ENGLISH ABSTRACT: In practice, there are many quality control situations where a product under consideration may have two or more interrelated quality characteristics and observations of each characteristic are serially correlated. One of the objectives of management is to investigate whether or not all these characteristics of the product simultaneously satisfy the required specifications. To the author's best knowledge, no concrete attempts have been made so far to construct the control charts for such situations, particularly when the data arise from vector autoregressive-moving average (VARMA processes. It is this problem that has been addressed in this paper. A few methods are suggested for constructing the control charts. When assumptions about independence and normality break down, a bootstrap method, perhaps for the first time, is suggested to attack the problem. Some illustrative examples are discussed.

    Full Text Available The influence of first language (L1 hereinafter  in the learning of second language  (L2 hereinafter has witnessed an intense debate during the past years, resulting in the prevalence of Error Analysis (EA hereinafter over Contrastive Analysis (CA hereinafter.  A great number of empirical studies indicated that neither L1 nor L2 was always responsible for learners' errors (Bailey et al. 1974; Krashen et al. 1978, 2003; Larsen-Freeman, 2002; 2003. CA and EA paved the way for Interlanguage theory (IL hereinafter in describing L2 learners' errors in the acquisition process of L2. IL, which has been in vogue for the last years, has witnessed huge criticism by different researchers and linguists from various L1 backgrounds. They all came to state that there are many points in this theory which are not clear. In light of this, this study aims at reviewing and discussing the role of  IL in describing and explaining learners' errors in the process of acquisition of L2.

    2009-01-01

    Molecular phylogenetic studies have become a major area of interest in plant systematics, and their impacts on historical biogeographic hypotheses are not to be disregarded. In Brazil, most historical biogeographic studies have relied on animal phylogenies, whereas plant biogeographic studies have largely lacked a phylogenetic component, having a limited utility for historical biogeography. That country, however, is of great importance for most biogeographic studies of lowland tropical South America, and it includes areas from a number of biogeographic regions of the continent. Important biogeographic reports have been published as part of phylogenetic studies, taxonomic monographs, and regional accounts for small areas or phytogeographic domains, hut the available information is subsequently scattered and sometimes hard to find. In this paper we review some relevant angiosperm biogeographic studies in Brazil. Initially we briefly discuss the importance of other continents as source areas for the South American flora. Then we present a subdivision of Brazil into phytogeographic domains, and we cite studies that have explored the detection of biogeographic units (areas of endemism) and how they are historically related among those domains. Examples of plant taxa that could be used to test some biogeographic hypotheses are provided throughout, as well as taxa that exemplify several patterns of endemism and disjunction in the Brazilian angiosperm flora.

  9. A review of microbiological studies. Pt. 1

    International Nuclear Information System (INIS)

    Safety assessment research programmes in the UK and other countries are considering the possible effect of microorganisms on waste and waste isolation materials in deep geological environments, including the degradation of organic wastes producing chelating/complexing agents capable of solubilising radionuclides making them more mobile; corrosion of steel and concrete isolation materials; alteration of groundwater chemistry; microbial gas generation and movement of radionuclides after sorption onto motile microorganisms. Early studies concentrated on reviewing the potential role of microorganisms in nuclear waste disposal, followed by an examination of relevant groundwater and sediment samples for microorganisms and microbial activity. A range of laboratory experiments have been devised to determine the biodegradation of organic wastes and the biodeterioration of waste isolation materials particularly steel, and have been supplemented with examination of relevant natural analogue sites. Such studies have shown that microorganisms will be most important in ILW and LLW repositories. (Author)

    Safety culture represents patterns of behavior and ways of thinking on safety for both individuals and organizations. Besides nuclear industry, many fields such as transport and health care have focused on the value and effectiveness of safety culture. In this paper, the definition and characteristics of just culture, which is one component of safety culture, and related studies reported by other researchers are described. We hope this review will serve to understand the current condition and underlying problems of the just culture of nuclear industry in Korea. This paper describes the definition and basic principle of just culture in nuclear industry based on the review of researches on safety and just culture in various fields. To establish just culture solidly in organization, each individual needs to understand the nature of the just culture first. And it is necessary to create an atmosphere encouraging to report and suggest safety-related issues. Most of all, to draw clear lines of blame and punishment for human error is essential.

  15. Impact of adverse events, treatment modifications, and dose intensity on survival among patients with advanced renal cell carcinoma treated with first-line sunitinib: a medical chart review across ten centers in five European countries

    International Nuclear Information System (INIS)

    Angiogenesis inhibitors have become standard of care for advanced and/or metastatic renal cell carcinoma (RCC), but data on the impact of adverse events (AEs) and treatment modifications associated with these agents are limited. Medical records were abstracted at 10 tertiary oncology centers in Europe for 291 patients ≥18 years old treated with sunitinib as first-line treatment for advanced RCC (no prior systemic treatment for advanced disease). Logistic regression models were estimated to compare dose intensity among patients who did and did not experience AEs during the landmark periods (18, 24, and 30 weeks). Cox proportional hazard models were used to explore the possible relationship of low-dose intensity (defined using thresholds of 0.7, 0.8, and 0.9) and treatment modifications during the landmark periods to survival. 64.4% to 67.9% of patients treated with sunitinib reported at least one AE of any grade, and approximately 10% of patients experienced at least one severe (grade 3 or 4) AE. Patients reporting severe AEs were statistically significantly more likely to have dose intensities below either 0.8 or 0.9. Dose intensity below 0.7 and dose discontinuation during all landmark periods were statistically significantly associated with shorter survival time. This study of advanced RCC patients treated with sunitinib in Europe found a significant relationship between AEs and dose intensity. It also found correlations between dose intensity and shorter survival, and between dose discontinuation and shorter survival. These results confirm the importance of tolerable treatment and maintaining dose intensity

  5. Preventable trauma deaths: from panel review to population based-studies

    Directory of Open Access Journals (Sweden)

    Vesconi Sergio

    2006-04-01

    Full Text Available Abstract Preventable trauma deaths are defined as deaths which could be avoided if optimal care has been delivered. Studies on preventable trauma deaths have been accomplished initially with panel reviews of pre-hospital and hospital charts. However, several investigators questioned the reliability and validity of this method because of low reproducibility of implicit judgments when they are made by different experts. Nevertheless, number of studies were published all around the world and ultimately gained some credibility, particularly in regions where comparisons were made before and after trauma system implementation with a resultant fall in mortality. During the last decade of century the method of comparing observed survival with probability of survival calculated from large trauma registries has obtained popularity. Preventable trauma deaths were identified as deaths occurred notwithstanding a high calculated probability of survival. In recent years, preventable trauma deaths studies have been replaced by population-based studies, which use databases representative of overall population, therefore with high epidemiologic value. These databases contain readily available information which carry out the advantage of objectivity and large numbers. Nowadays, population-based researches provide the strongest evidence regarding the effectiveness of trauma systems and trauma centers on patient outcomes.

  6. Synthetic-type control charts for time-between-events monitoring.

    Directory of Open Access Journals (Sweden)

    Fang Yen Yen

    Full Text Available This paper proposes three synthetic-type control charts to monitor the mean time-between-events of a homogenous Poisson process. The first proposed chart combines an Erlang (cumulative time between events, Tr chart and a conforming run length (CRL chart, denoted as Synth-Tr chart. The second proposed chart combines an exponential (or T chart and a group conforming run length (GCRL chart, denoted as GR-T chart. The third proposed chart combines an Erlang chart and a GCRL chart, denoted as GR-Tr chart. By using a Markov chain approach, the zero- and steady-state average number of observations to signal (ANOS of the proposed charts are obtained, in order to evaluate the performance of the three charts. The optimal design of the proposed charts is shown in this paper. The proposed charts are superior to the existing T chart, Tr chart, and Synth-T chart. As compared to the EWMA-T chart, the GR-T chart performs better in detecting large shifts, in terms of the zero- and steady-state performances. The zero-state Synth-T4 and GR-Tr (r = 3 or 4 charts outperform the EWMA-T chart for all shifts, whereas the Synth-Tr (r = 2 or 3 and GR-T 2 charts perform better for moderate to large shifts. For the steady-state process, the Synth-Tr and GR-Tr charts are more efficient than the EWMA-T chart in detecting small to moderate shifts.

  7. The use of quality control performance charts to analyze cesarean delivery rates nationally.

    LENUS (Irish Health Repository)

    Turner, Michael J

    2012-02-01

    OBJECTIVE: To examine the use of quality control performance charts to analyze cesarean rates nationally. METHODS: Information on cesarean rates was obtained for all 19 Irish maternity hospitals receiving state funding in 2009. All women who underwent cesarean delivery of a live or stillborn infant weighing 500 g or more between January 1 and December 31 were included. Deliveries were classified as elective or emergency. Individual hospitals were not identified in the analysis. RESULTS: The mean rates per hospital of elective and emergency cesarean were 12.9+\\/-2.6% (n=9337) and 13.8+\\/-3.0% (n=9989), respectively-giving an overall mean rate of 26.7+\\/-4.2% (n=19326) per hospital. Cesarean rates were normally distributed. Using a quality control performance chart with a cutoff 2 standard deviations from the mean, 1 hospital was above the normal range for both total and elective cesareans, indicating that its pre-labor obstetric practices warrant clinical review. Another hospital had a mean emergency cesarean rate above the normal range, indicating that its labor ward practices warrant review. CONCLUSION: Quality control performance charts can be used to analyze cesarean rates nationally and, thus, to identify hospitals at which obstetric practices should be reviewed.

  8. Idaho radionuclide exposure study: Literature review

    International Nuclear Information System (INIS)

    Phosphate ores contain elevated levels of natural radioactivity, some of which is released to the environment during processing or use of solid byproducts. The effect of radionuclides from Idaho phosphate processing operations on the local communities has been the subject of much research and study. The literature is reviewed in this report. Two primary radionuclide pathways to the environment have been studied in detail: (1) airborne release of volatile radionuclides, primarily 210Po, from calciner stacks at the two elemental phosphorus plants; and (2) use of byproduct slag as an aggregate for construction in Soda Springs and Pocatello. Despite the research, there is still no clear understanding of the population dose from radionuclide emissions, effluents, and solid wastes from phosphate processing plants. Two other potential radionuclide pathways to the environment have been identified: radon exhalation from phosphogypsum and ore piles and contamination of surface and ground waters. Recommendations on further study needed to develop a data base for a complete risk assssment are given in the report

  9. Radiological Review Studies On Ismailia Canal Ecology

    International Nuclear Information System (INIS)

    The present work is a brief review of pr-studies carried out on Ismailia Canal, Egypt, water ecosystem. Ismailia Canal water body is a bicarbonate stream with slight seasonal variations in its water chemical constituents. The canal water pH in all the stream locations are below 8.3 with low suspended matter(SM) content (22-33 mg.l-1). The mineralogical analysis of the canal bottom sediments consist mainly of quartz, smectite and kaolinite minerals. The γ- spectroscopic identification showed traces of naturally occurring radio nuclides (238U, 232Th and 40K). The average activity level of the dry samples ranged from 12 to 89 Bq.Kg-1 for the detected natural radio nuclides. Some parameters affected the sorption behaviour of radio nuclides on suspended matters and bottom sediments; such as solution pH, SM concentration, sediment grain size, carrier concentration and competing ions were studied. The reaction rates were investigated for each radionuclide studied. The distribution of the studied radio nuclides, between the liquid phase and the sediments phase was investigated, for both flowing and static systems. For both flowing and non-flowing (static), the depth penetration of the studied radio nuclides within the bottom sediment layers were found to vary from one radionuclide to the other. The total capacities of bottom sediments and the suspended matter were found to be low. As Ismailia Canal is an important source of water for public domestic uses, irrigation animals and the aquatic species; these situations have led to state that it is not recommended to release any liquid radioactive wastes to this canal. Furthermore, periodical radiometric analysis for the canal water and its components should be carried out.

  16. MDI Synoptic Charts of Magnetic Field: Interpolation of Polar Fields

    Science.gov (United States)

    Liu, Yang; Hoeksema, J. T.; Zhao, X.; Larson, R. M.

    2007-05-01

    In this poster, we compare various methods for interpolation of polar field for the MDI synoptic charts of magnetic field. By examining the coronal and heliospheric magnetic field computed from the synoptic charts based on a Potential Field Source Surface model (PFSS), and by comparing the heliospheric current sheets and footpoints of open fields with the observations, we conclude that the coronal and heliospheric fields calculated from the synoptic charts are sensitive to the polar field interpolation, and a time-dependent interpolation method using the observed polar fields is the best among the seven methods investigated.

    2011-01-01

    the distribution involved is negative binomial. However, in health care monitoring, (groups of patients will often belong to different risk categories. In the present paper, we will show how information about category membership can be used to adjust the basic negative binomial charts to the actual risk incurred. Attention is also devoted to comparing such conditional charts to their unconditional counterparts. The latter do take possible heterogeneity into account but refrain from risk-adjustment. Note that in the risk adjusted case several parameters are involved, which will all be typically unknown. Hence, the potentially considerable estimation effects of the new charts will be investigated as well.

  2. Paediatric Northern Score centile charts for the chest radiograph in cystic fibrosis

    International Nuclear Information System (INIS)

    Aim: To create the first national centile charts for the chest radiograph Northern Score using the UK Cystic Fibrosis (CF) Database (UKCFD). Materials and methods: All active patients for 2002 from the UKCFD were analysed in 1-year cohorts from 0 to 18 years. Northern Score results from the annual review forms were used to construct centile lines for the 5th, 25th, 50th, 75th, 95th centiles. Results: There were 1806 patients with recorded Northern Score data for 2002 (927 male patients, male:female ratio 1.05). The centile chart demonstrates a quasi-linear rise throughout childhood. A Northern Score in excess of age in years equates to >95th centile in school-aged CF patients. Conclusion: This centile chart provides a disease-specific reference range for monitoring individual patients or for evaluating therapeutic change using the dominant chest radiograph scoring system in the UK. Patients, parents and clinicians may find these useful during the annual review process

    2015-01-01

    Growth chart committee of Indian Academy of Pediatrics (IAP) has revised growth charts for 5-18-year-old Indian children in Jan 2015. The last IAP growth charts (2007) were based on data collected in 1989-92 which is now >2 decades old. India is in an economic and nutrition transition and hence growth pattern of Indian children has changed over last few years. Thus, it was necessary to produce contemporary, updated growth references for Indian children. The new IAP charts were prepared by collating data from nine groups who had published studies in indexed journals on growth from India in the last decade. Growth charts were constructed from a total of 87022 middle and upper socioeconomic class children (m 54086, f 32936) from all five zones of India. Data from middle and upper socioeconomic class children are likely to have higher prevalence of overweight and obesity and hence growth charts produced on such populations are likely to "normalize" obesity. To remove such unhealthy weights form the data, method suggested by World Health Organization was used to produce weight charts. Thus, the new IAP weight charts are much lower than the recently published studies on affluent Indian children. Since Indian's are at a higher risk of obesity-related cardiometabolic complications at lower body mass index (BMI), BMI charts adjusted for 23, and 27 adult equivalent cut-offs as per International obesity task force guidelines were constructed. IAP now recommends use of these new charts to replace the 2007 IAP charts. PMID:26180761

  6. Peer review of grant applications: criteria used and qualitative study of reviewer practices.

    Directory of Open Access Journals (Sweden)

    Hendy Abdoul

    Full Text Available BACKGROUND: Peer review of grant applications has been criticized as lacking reliability. Studies showing poor agreement among reviewers supported this possibility but usually focused on reviewers' scores and failed to investigate reasons for disagreement. Here, our goal was to determine how reviewers rate applications, by investigating reviewer practices and grant assessment criteria. METHODS AND FINDINGS: We first collected and analyzed a convenience sample of French and international calls for proposals and assessment guidelines, from which we created an overall typology of assessment criteria comprising nine domains relevance to the call for proposals, usefulness, originality, innovativeness, methodology, feasibility, funding, ethical aspects, and writing of the grant application. We then performed a qualitative study of reviewer practices, particularly regarding the use of assessment criteria, among reviewers of the French Academic Hospital Research Grant Agencies (Programmes Hospitaliers de Recherche Clinique, PHRCs. Semi-structured interviews and observation sessions were conducted. Both the time spent assessing each grant application and the assessment methods varied across reviewers. The assessment criteria recommended by the PHRCs were listed by all reviewers as frequently evaluated and useful. However, use of the PHRC criteria was subjective and varied across reviewers. Some reviewers gave the same weight to each assessment criterion, whereas others considered originality to be the most important criterion (12/34, followed by methodology (10/34 and feasibility (4/34. Conceivably, this variability might adversely affect the reliability of the review process, and studies evaluating this hypothesis would be of interest. CONCLUSIONS: Variability across reviewers may result in mistrust among grant applicants about the review process. Consequently, ensuring transparency is of the utmost importance. Consistency in the review process could

  8. The solar chart for designing shading devices for Tripoli City, Libya

    International Nuclear Information System (INIS)

    Due to lake of standardized methods to design and validate sun shading devices in Libya, this study aims at developing a solar chart, which can be used as a practical and systematic methodology for designing sun-shading devices in the city of Tripoli. In order to achieve the objective of this study, this paper was divided into five sections. The first section is dealing with a focused literature with respect to types of shading devices and their impact on the exterior wall opening, the person of the sun, sun's altitudes azimuths and how to mathematically be determined; the sun charts, and the shading calculator. While the second section was dedicated for the determination of the overheated periods over the year in which shading devices should be in place. The third section presents a computer software developed in order to automatically calculate the sun angles (Altitudes and Azimuth angles). The north latitude of 32.59 was chosen as a validation example. By using the statgraphics software, the output data were analyzed and illustrated in a solar chart that presents the equinox, summer and winter solstices. The resulted solar chart serves as a tool, which will jointly be used with the shading chart to design accurate shading devices for the chosen North latitude 32.59. The forth section explains the methodology of selecting an effective solar altitude and azimuth angles which an architect would on while designing sun shading devices. The fifth section, identifies and lists the methodology of designing each type of shading devices in the city of Tripoli. Libya. Finally, study conclusions were drawn, and further research studies were recommended to enhance the finding of this research paper. (author)

  9. System Behaviour Charts Inform an Understanding of Biodiversity Recovery

    Directory of Open Access Journals (Sweden)

    Simon A. Black

    2015-01-01

    Full Text Available Practitioners working with species and ecosystem recovery typically deal with the complexity of, on one hand, lack of data or data uncertainties and, on the other hand, demand for critical decision-making and intervention. The control chart methods of commercial and industrial and environmental monitoring can complement an ecological understanding of wildlife systems including those situations which incorporate human activities and land use. Systems Behaviour Charts are based upon well-established control chart methods to provide conservation managers with an approach to using existing data and enable insight to aid timely planning of conservation interventions and also complement and stimulate research into wider scientific and ecological questions. When the approach is applied to existing data sets in well-known wildlife conservation cases, the subsequent Systems Behaviour Charts and associated analytical criteria demonstrate insights which would be helpful in averting problems associated with each case example.

    2005-03-01

    A common approach to analyze geo-related data is using bar charts or x-y plots. They are intuitive and easy to use. But important information often gets lost. In this paper, we introduce a new interactive visualization technique called Geo Pixel Bar Charts, which combines the advantages of Pixel Bar Charts and interactive maps. This technique allows analysts to visualize large amounts of spatial data without aggregation and shows the geographical regions corresponding to the spatial data attribute at the same time. In this paper, we apply Geo Pixel Bar Charts to visually mining sales transactions and Internet usage from different locations. Our experimental results show the effectiveness of this technique for providing data distribution and exceptions from the map.

  13. Induction Chemotherapy and Continuous Hyperfractionated Accelerated Radiotherapy (CHART) for Patients With Locally Advanced Inoperable Non-Small-Cell Lung Cancer: The MRC INCH Randomized Trial

    International Nuclear Information System (INIS)

    Purpose: Recent clinical trials and meta-analyses have shown that both CHART (continuous hyperfractionated accelerated radiation therapy) and induction chemotherapy offer a survival advantage over conventional radical radiotherapy for patients with inoperable non-small cell-lung cancer (NSCLC). This multicenter randomized controlled trial (INCH) was set up to assess the value of giving induction chemotherapy before CHART. Methods and Materials: Patients with histologically confirmed, inoperable, Stage I-III NSCLC were randomized to induction chemotherapy (ICT) (three cycles of cisplatin-based chemotherapy followed by CHART) or CHART alone. Results: Forty-six patients were randomized (23 in each treatment arm) from 9 UK centers. As a result of poor accrual, the trial was closed in December 2007. Twenty-eight patients were male, 28 had squamous cell histology, 34 were Stage IIIA or IIIB, and all baseline characteristics were well balanced between the two treatment arms. Seventeen (74%) of the 23 ICT patients completed the three cycles of chemotherapy. All 42 (22 CHART + 20 ICT) patients who received CHART completed the prescribed treatment. Median survival was 17 months in the CHART arm and 25 months in the ICT arm (hazard ratio of 0.60 [95% CI 0.31-1.16], p = 0.127). Grade 3 or 4 adverse events (mainly fatigue, dysphagia, breathlessness, and anorexia) were reported for 13 (57%) CHART and 13 (65%) ICT patients. Conclusions: This small randomized trial indicates that ICT followed by CHART is feasible and well tolerated. Despite closing early because of poor accrual, and so failing to show clear evidence of a survival benefit for the additional chemotherapy, the results suggest that CHART, and ICT before CHART, remain important options for the treatment of inoperable NSCLC and deserve further study.

  17. Diagnosing diabetic foot infection: the role of imaging and a proposed flow chart for assessment

    International Nuclear Information System (INIS)

    Diabetes mellitus, a major current epidemic, is frequently complicated by foot infections that are associated with high morbidity. Diagnosing these infections, especially whether or not underlying bone is involved, poses clinical challenges, but is crucial to making proper decisions regarding therapeutic strategies. The most effective means of managing patients with a diabetic foot infection is within the framework of a multidisciplinary team. Present diagnostic efforts are aimed at developing better methods to differentiate uninfected from infected soft tissue wounds, to determine when bone infection is present, and to more clearly define when infection has resolved with treatment. Imaging studies play a major role in diagnosis. This usually begins with plain radiographs, but when advanced imaging is needed, magnetic resonance imaging (MRI) is considered the modality of choice. Newer techniques, such as molecular hybrid imaging, positron emission tomography (PET)/computed tomography (CT) and single photon emission (SPECT)/CT using various radiotracers, play an increasing role. These tests may redefine the non-invasive diagnostic work-up of diabetic foot wounds, potentially leading to substantial improvements in patient management. As experts in infectious diseases, radiology and nuclear medicine, we reviewed the available literature on diagnosing diabetic foot infections, especially the currently available imaging techniques, and developed a proposed diagnostic flow chart, for evaluating patients with a diabetic foot wound

  18. Seasonal ARMA-based SPC charts for anomaly detection: Application to emergency department systems

    KAUST Repository

    Kadri, Farid

    2015-10-22

    Monitoring complex production systems is primordial to ensure management, reliability and safety as well as maintaining the desired product quality. Early detection of emergent abnormal behaviour in monitored systems allows pre-emptive action to prevent more serious consequences, to improve system operations and to reduce manufacturing and/or service costs. This study reports the design of a new methodology for the detection of abnormal situations based on the integration of time-series analysis models and statistical process control (SPC) tools for the joint development of a monitoring system to help supervising of the behaviour of emergency department services (EDs). The monitoring system developed is able to provide early alerts in the event of abnormal situations. The seasonal autoregressive moving average (SARMA)-based exponentially weighted moving average (EWMA) anomaly detection scheme proposed was successfully applied to the practical data collected from the database of the paediatric emergency department (PED) at Lille regional hospital centre, France. The method developed utilizes SARMA as a modelling framework and EWMA for anomaly detection. The EWMA control chart is applied to the uncorrelated residuals obtained from the SARMA model. The detection results of the EWMA chart are compared with two other commonly applied residual-based tests: a Shewhart individuals chart and a Cumulative Sum (CUSUM) control chart.

  19. Visual mining business service using pixel bar charts

    2004-06-01

    Basic bar charts have been commonly available, but they only show highly aggregated data. Finding the valuable information hidden in the data is essential to the success of business. We describe a new visualization technique called pixel bar charts, which are derived from regular bar charts. The basic idea of a pixel bar chart is to present all data values directly instead of aggregating them into a few data values. Pixel bar charts provide data distribution and exceptions besides aggregated data. The approach is to represent each data item (e.g. a business transaction) by a single pixel in the bar chart. The attribute of each data item is encoded into the pixel color and can be accessed and drilled down to the detail information as needed. Different color mappings are used to represent multiple attributes. This technique has been prototyped in three business service applications-Business Operation Analysis, Sales Analysis, and Service Level Agreement Analysis at Hewlett Packard Laboratories. Our applications show the wide applicability and usefulness of this new idea.

    2010-10-01

    Full Text Available The Hotelling's T2 control chart is widely used to identify out–of–control signals in multivariate processes. However, this chart is not sensitive to small shifts in the process mean vec tor. In this work we propose a control chart to identify out–of–control signals. The proposed chart is a combination of Hotelling's T2 chart, M chart proposed by Hayter et al. (1994 and a new chart based on Principal Components. The combination of these charts identifies any type and size of change in the process mean vector. Us ing simulation and the Average Run Length (ARL, the performance of the proposed control chart is evaluated. The ARL means the average points within control before an out–of–control point is detected, The results of the simulation show that the proposed chart is more sensitive that each one of the three charts individually

    OBJECTIVE: To summarize Cochrane reviews of acupuncture for neurological disorders, and characteristics of included reviews and studies.DATA SOURCES: A computer-based online search of the Cochrane Library (Issue 7 of 12, July 2010) was performed with the key word "acupuncture" and systematic evaluations for acupuncture for neurological disorders were screened.STUDY SELECTION: Systematic reviews on acupuncture in the treatment of neurological disorders were included, and the characteristics of these reviews were analyzed based on methods recommended by the Cochrane collaboration.MAIN OUTCOME MEASURES: Basic characteristics, methodological quality, main reasons for excluding trials, results and conclusions of Cochrane reviews were assessed.RESULTS: A total of 18 Cochrane systematic reviews were included, including 13 completed reviews and five research protocols. The 13 completed reviews involved 111 randomized controlled trials, including 43 trials (38.7%) conducted in China, 47 trials (42.3%) using sham-acupuncture or placebo as control, 15 trials (13.5%) with relatively high quality, 91 trials (81.9%) reporting data on follow-up. Primary outcomes used in the Cochrane reviews were reported by 65 trials (58.6%), and adverse events were reported in 11 trials (9.9%). Two hundred and eighty three trials were excluded. Two reviews on headache suggested that acupuncture is a valuable non-drug treatment for patients with chronic or recurrent headache, and has better curative effects on migraine compared with preventative drug treatment. CONCLUSION: Of the Cochrane reviews on acupuncture in the treatment of neurological disorders, two reviews evaluating the efficacy of acupuncture in treating headaches drew positive conculsions, while other reviews did not obtain positive conclusions due to a small sample size or low methodological quality. The methodological quality of acupuncture trials needs further improvement.

    Genes reside in particular genomic contexts that can be mapped at many levels. Historically, 'genetic maps' were used primarily to locate genes. Recent technological advances in the determination of genome sequences have made the analysis and comparison of whole genomes possible and increasingly tractable. What do we see if we shift our focus from gene content (the 'inventory' of genes contained within a genome) to the composition and organization of a genome? This review examines what has been learned about the evolution of the apicomplexan genome as well as the significance and impact of genomic location on our understanding of the eukaryotic genome and parasite biology.

    With advantages of large capacity, long distance, low energy consumption, low cost, less land occupation and light pollution, inland waterway transportation becomes one of the most important constituents of the comprehensive transportation system and comprehensive water resources utilization in China. As one of "three elements" of navigation, waterway is the important basis for the development of water transportation and plays a key supporting role in shipping economic. The paper discuss how to realize the informatization and digitization of waterway management based on constructing an integrated system of standard inland electronic navigation chart production, waterway maintenance, navigation mark remote sensing and control, ship dynamic management, and water level remote sensing and report, which can also be the foundation of the intelligent waterway construction. Digital waterway construction is an information project and also has a practical meaning for waterway. It can not only meet the growing high assurance and security requirements for waterway, but also play a significant advantage in improving transport efficiency, reducing costs, promoting energy conservation and so on. This study lays a solid foundation on realizing intelligent waterway and building a smooth, efficient, safe, green modern inland waterway system, and must be considered as an unavoidable problem for the coordinated development between "low carbon" transportation and social economic.

    Astrobiology is the study of the origin, evolution and distribution of life in the universe. It provides a biological perspective to many areas of NASA research. It links such endeavors as the search for habitable planets, exploration missions to Mars and the outer Solar System, efforts to understand the origins and early evolution of life, and charting the potential of life to adapt to future challenges, both on Earth and in space. Astrobiology addresses the following three basic questions, which have been asked in some form for generations. How does life begin and evolve? Does life exist elsewhere in the universe? What is future of life on Earth and beyond? The NASA Astrobiology Roadmap provides guidance for research and technology development across several NASA Enterprises: Space Science, Earth Science, and the Human Exploration and Development of Space. The Roadmap is formulated in terms of eight Science Goals that outline key domains of investigation that might require perhaps decades of effort to consolidate. For each of these goals, Science Objectives outline more specific high priority near-term efforts for the next three to five years. These twenty objectives will be integrated with NASA strategic planning.

    Many people use religious beliefs and practices to cope with stressful life events and derive peace of mind and purpose in life. The goal of this paper was to systematically review the recent psychological literature to assess the role of religion in mental health outcomes. A comprehensive literature search was conducted using medical and psychological databases on the relationship between religiosity and mental health. Seventy-four articles in the English and Arabic languages published between January 2000 and March 2012 were chosen. Despite the controversial relationship between religion and psychiatry, psychology, and medical care, there has been an increasing interest in the role which spirituality and religion play in mental health. The findings of past research showed that religion could play an important role in many situations, as religious convictions and rules influence the believer's life and health care. Most of the past literature in this area reported that there is a significant connection between religious beliefs and practices and mental health. PMID:27654836

    This report summarizes and comments on relevant solar energy market surveys and related studies to provide a basis for determining areas requiring additional research and possible policies and actions to aid in rapid adoption of solar technologies. Thirty-two studies are discussed. The first 19 studies directly assess the market for residential use of solar domestic hot water, space, and pool heating. Studies 20 and 21 inspect energy conservation surveys. Studies 22 and 23 examine the financial incentives and financial institutions in the expanding solar market. Study 24 considers energy and low-income people. Studies 25 and 26 assess market sizes for photovoltaic systems and wind machines. Studies 27 to 30 are not surveys per se, but represent secondary source and modeling efforts to gain understanding of the solar marketplace. Studies 31 and 32 present the Canadian perspective on the market feasibility of solar energy systems. Many of the studies contained flaws of concept and/or method to a degree that would bring into question the credibility of individual findings but, taken as an aggregrate, they provide a useful compendium of opinion about present and potential solar energy users.

    Magerman, D M; Magerman, David M.; Weir, Carl

    1994-01-01

    This paper describes Picky, a probabilistic agenda-based chart parsing algorithm which uses a technique called {\\em probabilistic prediction} to predict which grammar rules are likely to lead to an acceptable parse of the input. Using a suboptimal search method, Picky significantly reduces the number of edges produced by CKY-like chart parsing algorithms, while maintaining the robustness of pure bottom-up parsers and the accuracy of existing probabilistic parsers. Experiments using Picky demonstrate how probabilistic modelling can impact upon the efficiency, robustness and accuracy of a parser.

  6. The effects of parameter estimation on minimizing the in-control average sample size for the double sampling X bar chart

    Directory of Open Access Journals (Sweden)

    Michael B.C. Khoo

    2013-11-01

    Full Text Available The double sampling (DS X bar chart, one of the most widely-used charting methods, is superior for detecting small and moderate shifts in the process mean. In a right skewed run length distribution, the median run length (MRL provides a more credible representation of the central tendency than the average run length (ARL, as the mean is greater than the median. In this paper, therefore, MRL is used as the performance criterion instead of the traditional ARL. Generally, the performance of the DS X bar chart is investigated under the assumption of known process parameters. In practice, these parameters are usually estimated from an in-control reference Phase-I dataset. Since the performance of the DS X bar chart is significantly affected by estimation errors, we study the effects of parameter estimation on the MRL-based DS X bar chart when the in-control average sample size is minimised. This study reveals that more than 80 samples are required for the MRL-based DS X bar chart with estimated parameters to perform more favourably than the corresponding chart with known parameters.

    Full Text Available Background: Reference charts are widely used in healthcare as a screening tool. This study aimed to produce reference growth charts for school children from West Malaysia in comparison with the United States Centers for Disease Control and Prevention (CDC chart.Methods: A total of 14,360 school children ranging from 7 to 17 years old from six states in West Malaysia were collected. A two-stage stratified random sampling technique was used to recruit the subjects. Curves were adjusted using Cole's LMS method. The LOWESS method was used to smooth the data.Results: The means and standard deviations for height and weight for both genders are presented. The results showed good agreement with growth patterns in other countries, i.e., males tend to be taller and heavier than females for most age groups. Height and weight of females reached a plateau at 17 years of age; however, males were still growing at this age. The growth charts for West Malaysian school children were compared with the CDC 2000 growth charts for school children in the United States.Conclusion: The height and weight for males and females at the start of school-going ages were almost similar. The comparison between the growth charts from this study and the CDC 2000 growth charts indicated that the growth patterns of West Malaysian school children have improved, although the height and weight of American school children were higher than those for West Malaysian school children.

    2001-12-01

    Biological aspects of electromagnetic compatibility (Bio-EMC) have been studied by EMC Research Group of CRL. There are two main subjects in the field. One is related to rules and regulations of electromagnetic-wave hazards, especially development of standard estimation methods of electromagnetic power deposited in human bodies exposed to microwaves from cellular telephones or VHF-band radio waves. Another is development of exposure setups for laboratory animals used in biological studies on health effects of electromagnetic waves and their dosimetry. Novel phantoms are also being developed in order to perform highly accurate dosimetry in above studies. It is expected that these studies contribute development of compliance tests for radiofrequency protection guidelines and improvement of rationale of those guidelines, which consequently provides safety environment including appropriate radio wave applications.

  11. SU-D-BRD-02: Auto Weekly - An Automated Online Weekly Chart Check System for Medical Physics

    International Nuclear Information System (INIS)

    Purpose: Radiation therapy has evolved to become not only more precise and potent, but also more complicated to monitor and deliver. More rigorous and comprehensive quality assurance is needed to safeguard ever advancing radiation therapy. ICRU standards dictate that an ever growing set of treatment parameters are manually checked weekly by medical physicists. This “weekly chart check” procedure is laborious and subject to human errors or other factors. A computer-assisted chart checking process will enable more complete and accurate human review of critical parameters, reduce the risk of medical errors, and improve the efficiency. Methods: We developed a web-based software system that enables a thorough weekly quality assurance checks. In the backend, the software retrieves all machine parameters from a Treatment Management System (TMS) and compares them against the corresponding ones from the treatment planning system. They are also checked for validity against preset rules. The results are displayed as a web page in the front-end for physicists to review. Then a summary report is generated and uploaded automatically to the TMS as a record for weekly chart checking. Results: The software system has been deployed on a web server in our department’s intranet, and has been tested thoroughly by our clinical physicists. A plan parameter would be highlighted when it is off the preset limit. The developed system has changed the way of checking charts with significantly improved accuracy, efficiency, and completeness. It has been shown to be robust, fast, and easy to use. Conclusion: A computer-assisted system has been developed for efficient, accurate, and comprehensive weekly chart checking. The system has been extensively validated and is being implemented for routine clinical use

    Despite acknowledgement of the importance of executive control for learning and behavior, there is a dearth of research charting its developmental trajectory as it unfolds against the background of children's sociofamilial milieus. Using a prospective, cohort-sequential design, this study describes growth trajectories for inhibitory control and cognitive flexibility across the preschool period in relation to child sex and sociofamilial resources. At ages 3, 3.75, 4.5, and 5.25 years, children (N = 388) from a broad range of social backgrounds were assessed using the Shape School, a graduated measure of executive control incorporating baseline, inhibitory control, and cognitive flexibility conditions. Measures of children's proximal access to learning resources and social network supports were collected at study entry. Findings revealed substantial gains in accuracy and speed for all Shape School conditions, these gains being particularly accelerated between ages 3 and 3.75 years. Improvements in inhibitory control were more rapid than those in flexible switching. Age-related differences in error and self-correction patterns on the Shape School also suggest qualitative changes in the underlying processes supporting executive performance across early childhood. Children from homes with fewer learning resources showed a subtle lag in inhibition and cognitive flexibility performance that persisted at kindergarten entry age, despite exhibiting gradual catch up to their more advantaged peers for the nonexecutive, baseline task condition. The study provides a unique characterization of the early developmental pathways for inhibitory control and cognitive flexibility and highlights the critical role of stimulating early educational resources for shaping the dynamic ontogeny of executive control.

    2002-01-01

    (X)charts with estimated control limits are commonly used in practice andtreated as if the in-control process parameters were known. However, the former canbehave quite differently from the latter. To understand the differences, it is necessary tostudy the run length distribution (RLD), its mean (ARL) and standard deviation (SDRL)of the (X)charts when the control limits are estimated. However, ARL and SDRL areintegrals over an infinite region with a boundless integrand, the finiteness has not beenproved in literature. In this paper, we show the finiteness and uniform integrability ofARL and SDRL. Furthermore, we numerically evaluate the ARL, SDRL and the RLDusing number theory method. A numerical study is conducted to assess the performanceof the proposed method and the results are compared with those given by Quesenberryand Chen.

  19. Intertextuality and Biblical Studies: A Review

    Directory of Open Access Journals (Sweden)

    S. Moyise

    2002-08-01

    Full Text Available The literary term 'intertextuality' was introduced into biblical studies in 1989 and concerns the complex relationships that exist between texts. Not surprisingly, this was of interest to those who study the use of the Old Testament in the New, for old texts appear to be given new meaning by being used in new contexts. In this article, I demonstrate the fruitfulness of this approach by offering a survey of five different �types� of intertextuality currently in use today. I conclude that if scholars wish to continue to use the term, they need to clarify which 'type' of intertextuality they are using, so that readers can know what is being claimed.

    Nuclear data is critical to research fields from medicine to astrophysics. The chart of nuclides is a more descriptive version of the periodic table that can be used to visualize nuclear properties such as half-lives and mass. We have created ICoN (simply short for Interactive Chart of Nuclides), an API which can be used to visualize theoretical and experimental datasets. This visualization is achieved by using D3 (Data Driven Documents), HTML, and CSS3 to plot the elements and color them accordingly. ICoN features many customization options that users can access that are dynamically applied to the chart without reloading the page. Users can save the customized chart they create to various formats. We have constructed these features in order to provide a unique approach for researchers to interface with nuclear data. ICoN can also be used on all electronic devices without loss of support. We report on the current progress of this project and will present a working demo that highlights each aspect of the aforementioned features. This is the first time that all available technologies are put to use to make nuclear data more accessible than ever before. This is a first and we will make it available as open source ware.

    Determine feasibility and toxicity of preoperative short course pelvic CHART (25 Gy in 15 fractions over 5 days) for treatment of clinically resectable primary rectal tumours. Between 1998 and 2004, 20 patients with clinically staged T3 resectable rectal carcinoma were treated in this prospective pilot study with preoperative short course CHART to their pelvis. The aim was for total mesorectal excision within 7 days. Radiation toxicity, surgical morbidity, locoregional control (LRC), overall (OS), cause specific (CSS) and disease free survival (DFS) outcomes were documented. Nineteen of the 20 patients completed planned radiotherapy. One discontinued radiotherapy due to toxicity. All patients underwent potentially curative radical surgery. One patient developed grade 3, and three patients grade 2 gastrointestinal toxicity. With a median follow-up of 31 months (range 0.9-88), there is no grade 3, 4 or 5 late toxicity. Two patients experienced grade 2, and three patients grade 1 late bowel toxicity. Two patients died from postoperative complications, and two developed grade 2 abdominal wound infections. At 3 years LRC is 95% (95% CI 83-100), OS 72% (95% CI 51-94), CSS 86% (95% CI 68-100) and DFS 80% (95% CI 60-100). Two patients died from metastatic disease, one patient from a second primary and one patient is alive after successful resection of hepatic metastases. This small study suggests preoperative short course CHART for clinically resectable rectal carcinoma is feasible with acceptable compliance and tolerable side effects.

  4. MINIMIZING GLOVEBOX GLOVE BREACHES, PART IV: CONTROL CHARTS

    International Nuclear Information System (INIS)

    At the Los Alamos National Laboratory (LANL) Plutonium Facility, plutonium. isotopes and other actinides are handled in a glovebox environment. The spread of radiological contamination, and excursions of contaminants into the worker's breathing zone, are minimized and/or prevented through the use of glovebox technology. Evaluating the glovebox configuration, the glovebo gloves are the most vulnerable part of this engineering control. Recognizing this vulnerability, the Glovebox Glove Integrity Program (GGIP) was developed to minimize and/or prevent unplanned openings in the glovebox environment, i.e., glove failures and breaches. In addition, LANL implement the 'Lean Six Sigma (LSS)' program that incorporates the practices of Lean Manufacturing and Six Sigma technologies and tools to effectively improve administrative and engineering controls and work processes. One tool used in LSS is the use of control charts, which is an effective way to characterize data collected from unplanned openings in the glovebox environment. The benefit management receives from using this tool is two-fold. First, control charts signal the absence or presence of systematic variations that result in process instability, in relation to glovebox glove breaches and failures. Second, these graphical representations of process variation detennine whether an improved process is under control.

  5. Minimizing glovebox glove breaches, Part 4: control charts

    International Nuclear Information System (INIS)

    At the Los Alamos National Laboratory (LANL) Plutonium Facility, plutonium isotopes and other actinides are handled in a glovebox environment. The spread of radiological contamination, and excursions of contaminants into the worker's breathing zone, are minimized and/or prevented through the use of glovebox technology. Evaluating the glovebox configuration, the glovebox gloves are the most vulnerable part of this engineering control. Recognizing this vulnerability, the Glovebox Glove Integrity Program was developed to minimize and/or prevent unplanned openings in the glovebox environment, e.g., glove failures and breaches. In addition, LANL implement the 'Lean Six Sigma (LSS)' program that incorporates the practices of Lean Manufacturing and Six Sigma technologies and tools to effectively improve administrative and engineering controls and work processes. One tool used in LSS is the use of control charts, which is an effective way to characterize data collected from unplanned openings in the glovebox environment. The benefit management receives from using this tool is two-fold. First, control charts signal the absence or presence of systematic variations that result in process instability, in relation to glovebox glove breaches and failures. Second, these graphical representations of process variation determine whether an improved process is under control. Further, control charts are used to identify statistically significant variations (trends) that can be used in decision making to improve processes.

  7. A parathyroid adenoma case study: Protocol review

    International Nuclear Information System (INIS)

    Full text: Technetium-99m (99mTc) Sestamibi as opposed to Thallous-201 Chloride and 99mTc Sodium Pertechnetate subtraction, has become the radiopharmaceutical of choice for detection of parathyroid adenomas. A 17-year-old female patient presented to the department for a parathyroid 99mTc Sestamibi scan to evaluate possible parathyroid adenoma/s. She was initially admitted with increasing serum Calcium levels, polyuria, abdominal pain and general malaise. The patient was injected with 900MBq of 99mTc Sestamibi, and a pinhole dynamic at a distance of 10 cm from the neck was acquired followed by a 5-minute static image at 7 cm. Single Photon Emission Computed Tomography (SPECT) was then performed on a dual-head gamma camera followed by an anterior and posterior 10-minute static image. At 3 and 5 hours post injection the 10-minute static image was repeated. This study was reported as normal with uniform uptake and washout of the tracer over the 5-hour period. An ultrasound study was performed, and it showed a lesion believed to be a parathyroid adenoma measuring 2.2 x 0.8 x 0.4 cm in size in the right upper lobe of the thyroid. A subsequent thyroid scan was performed to confirm that it was non-functioning thyroid tissue. The patient was injected with 250MBq of 99mTc Sodium Pertechnetate and scanned with a pinhole collimator at a distance of 7 cm. When the 99mTc Sestamibi and 99mTc Sodium Pertechnetate scan were viewed together, it was clear that there was excess 99mTc Sestamibi distribution on the right upper lobe of the thyroid, which washed out over time. This corresponded to the ultrasound findings and was confirmed at surgery to be a parathyroid adenoma. A 99mTc Sodium Pertechnetate scan and an ultrasound are now also routinely performed on patients presenting for 99mTc Sestamibi parathyroid scans

  8. Contact freezing: a review of experimental studies

    Directory of Open Access Journals (Sweden)

    L. A. Ladino Moreno

    2013-10-01

    Full Text Available This manuscript compiles both theoretical and experimental information on contact freezing with the aim to better understand this potentially important but still not well quantified heterogeneous freezing mode. There is no complete theory that describes contact freezing and how the energy barrier has to be overcome to nucleate an ice crystal by contact freezing. Experiments on contact freezing conducted using the cold plate technique indicate that it can initiate ice formation at warmer temperatures than immersion freezing. Additionally, a qualitative difference in the freezing temperatures between contact and immersion freezing has been found using different instrumentation and different ice nuclei. There is a lack of data on collision rates in most of the reported data, which inhibits a quantitative calculation of the freezing efficiencies. Thus, new or modified instrumentation to study contact nucleation in the laboratory and in the field are needed to identify the conditions at which contact nucleation could occur in the atmosphere. Important questions concerning contact freezing and its potential role for ice cloud formation and climate are also summarized.

  13. The first published chart of the Andromeda Nebula, 1667

    2014-06-01

    The Parisian astronomer Ismaél Bullialdus (1605-1694) is known for his planetary tables (Astronomia philolaica, 1645) based on a geometrical approximation to the Keplerian ellipse, and for his long correspondence with the Danzig astronomer Johannes Hevelius and with Christiaan Huygens. Bullialdus became interested in the nascent study of variable stars, and in 1667 published a small pamphlet with two contributions, one on Mira Ceti and the other on the nebula in Andromeda. He found a manuscript portraying the nebula with the date 1428, and because Tycho Brahe never mentioned a nebula in Andromeda, Bullialdus conjectured that this object was a variable that had disappeared in the intervening era. “We conclude this since this conglomeration was observed neither by Hipparchus nor anyone else in antiquity, nor in the previous age by Tycho, nor in the age of our forefathers like Bayer.” His publication included a handsome engraving of the image of Andromeda and the position of the nebula, its first printed chart. I recently acquired a copy of this rare pamphlet, Ad astronomos monita duo, and realized that the image matched a manuscript now in the Gotha Research Library, a 15th-century Latin version based on the work of the tenth-century Islamic astronomer, al-Sufi. The manuscript does not carry the name of al-Sufi, and hence Bullialdus had no real clue about its origin or its date of composition. Paul Kunitzsch (The Arabs and the Stars, 1989, Article XI, “The Astronomer Abu ’l-Husayn al-Sufi”) has identified a group of eight “Latin al-Sufi” manuscripts from this period, scattered in European libraries, but only the one now in Gotha is an exact match to Bullialdus’ engraving. The al-Sufi manuscript was given to the Gotha Library in 1798 by Duke Ernst II of Saxonia-Gotha-Altenburg, who must have acquired it from France sometime in the 18th century.

  14. Development of dental charts according to tooth development and eruption for Turkish children and young adults

    International Nuclear Information System (INIS)

    In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al. In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengston's system, which was modified by AlQahtani et al at four points. Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders. The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.

    2014-09-01

    Full Text Available Traditionally, Control Chart Patterns (CCP is widely used as a powerful method to measure, classify,analyze and interpret process data to improve the quality of products and service by detecting instabilities and justifying possible causes. In this study, we have developed an expert system that we called an expert system for control chart patterns recognition for recognition of the common types of control chart patterns (CCPs. The proposed system includes three main modules: the feature extraction module, the classifier module and the optimization module. In the feature extraction module, the multi-resolution wavelets (MRW are proposed as the effective features for representation of CCPs. In the classifier module, the adaptive neuro-fuzzy inference system (ANFIS is investigated. In ANFIS training, the vector of radius has a very important role for its recognition accuracy. Therefore, in the optimization module, imperialist competitive algorithm(ICA is proposed for finding optimum vector of radius. Simulation results show that the proposed system has high recognition accuracy.

  18. Reviewing existing knowledge prior to conducting animal studies.

    Science.gov (United States)

    Knight, Andrew

    2008-12-01

    Highly polarised viewpoints about animal experimentation have often prevented agreement. However, important common ground between advocates and opponents was demonstrated within a discussion forum hosted at www.research-methodology.org.uk in July-August 2008, by the independent charity, SABRE Research UK. Agreement existed that many animal studies have methodological flaws - such as inappropriate sample sizes, lack of randomised treatments, and unblinded outcome assessments - that may introduce bias and limit statistical validity. There was also agreement that systematic reviews of the human utility of animal models yield the highest quality of evidence, as their reliance on methodical and impartial methods to select significant numbers of animal studies for review, serves to minimise bias. Unfortunately, disagreement remained that animal experimental licence applications should reference systematic reviews of existing studies, before approval. The UK Medical Research Council requires that researchers planning human clinical trials must reference such reviews of related previous work. Existing knowledge is thereby fully and appropriately utilised, and redundant experimentation is avoided. However, objections were raised that a similar requirement would interfere with animal experimental licensing, because, to date, there have been very few systematic reviews of animal studies. In fact, the relative dearth of such reviews is a matter of considerable concern, and may partially explain the very poor human success rates of drugs that appear safe and/or efficacious in animal trials. Nevertheless, the disturbing number of human trials which have proceeded concurrently with, or prior to, animal studies, or have continued despite equivocal evidence of efficacy in animals, clearly demonstrate that many researchers fail to conduct adequate prior reviews of existing evidence.

    The golden ratio has been studied since the ancient Greeks due to its inherent symmetry and aesthetic beauty, especially in the five Platonic Solids. The golden mean is now established as a pillar of El Naschie's E infinity where it achieves the physical manifestation of 0.618 034 MeV. The largest atomic electron orbital total energies average to the golden mean energy. This paper examines the golden ratio in order to expand upon a century old attempt to produce a relatively static, visual, geometric model of atomic structure.

  1. Integrated thermal treatment systems study. Internal review panel report

    International Nuclear Information System (INIS)

    The U.S. Department of Energy (DOE) Office of Technology Development (OTD) commissioned two studies to evaluate nineteen thermal treatment technologies for treatment of DOE mixed low-level waste. These studies were called the Integrated Thermal Treatment System (ITTS) Phase I and Phase II. With the help of the DOE Office of Environmental Management (EM) Mixed Waste Focus Group, OTD formed an ITTS Internal Review Panel to review and comment on the ITTS studies. This Panel was composed of scientists and engineers from throughout the DOE complex, the U.S. Environmental Protection Agency, the California EPA, and private experts. The Panel met from November 15-18, 1994 to review the ITTS studies and to make recommendations on the most promising thermal treatment systems for DOE mixed low-level wastes and on research and development necessary to prove the performance of the technologies. This report describes the findings and presents the recommendations of the Panel

  2. A Variable Sampling Interval Synthetic Xbar Chart for the Process Mean.

    Directory of Open Access Journals (Sweden)

    Lei Yong Lee

    Full Text Available The usual practice of using a control chart to monitor a process is to take samples from the process with fixed sampling interval (FSI. In this paper, a synthetic X control chart with the variable sampling interval (VSI feature is proposed for monitoring changes in the process mean. The VSI synthetic X chart integrates the VSI X chart and the VSI conforming run length (CRL chart. The proposed VSI synthetic X chart is evaluated using the average time to signal (ATS criterion. The optimal charting parameters of the proposed chart are obtained by minimizing the out-of-control ATS for a desired shift. Comparisons between the VSI synthetic X chart and the existing X, synthetic X, VSI X and EWMA X charts, in terms of ATS, are made. The ATS results show that the VSI synthetic X chart outperforms the other X type charts for detecting moderate and large shifts. An illustrative example is also presented to explain the application of the VSI synthetic X chart.

  3. Charting Phelan's 'To Suffer a Sea Change'.

    Physicians and healthcare workers usually perceive their medical record entries as documentation rather than construction. In the following article, we extract a medical record from a narrative, Peggy Phelan's pathography of glaucoma, 'To Suffer a Sea Change'. From information about encounters described by Phelan, an ophthalmologist reconstructs progress notes similar to those that would be key to a glaucoma patient's medical record. Rather than condemning the arcane pointilism of the medical record as a poverty of language, or isolating the pathography as an academic text, we hope to instead appreciate what their collaborative dialogue offers the study of disease. While the points of divergence between these texts will demonstrate failures in communication, they will also unearth an enriched dialogue.

Objectives: (i To observe application of the growth monitoring charts provided in the Mother and Child Protection (MCP Card by health care providers in Village Health and Nutrition Day (VHND setting in rural Kamrup. (ii To assess whether their applied methods and interpretations are appropriate. (iii To identify gaps in relation to growth monitoring. Materials and Methods: A cross-sectional study was conducted during January-July 2014 in VHND sessions covering 44 villages selected through multistage sampling in Kamrup district in Assam. 88 Auxiliary Nurses and Midwives (ANM and 34 Anganwadi Workers (AWW present in the sessions were closely observed during their activities and then interviewed regarding their interpretations of the growth chart. Results: 77% of the AWWs present were involved in growth assessment and weight plotting in growth charts of all the 0-36 months aged children brought to a session.  Correct plotting of weight and interpretations of the growth charts were known to 94% of the AWWs and only 69% of the ANMs. Conclusion: Growth monitoring charts provided in the MCP card were not found to be optimally applied for community based growth monitoring in rural Kamrup. Deficiency was found in the ANMs regarding their applied methods and interpretations of the growth charts in comparison to the AWWs. AWWs were inadequately involved in growth assessment and monitoring of children in the vulnerable age group of 0-36 months in the VHND sessions.

Methods: We studied 65 eyes undergoing vitrectomy for unilateral ERM. Self-administered questionnaires were used to examine the metamorphopsia in their daily life. The degree of metamorphopsia was determined by M-CHARTS. The receiver operating characteristic curve was used to determine the best predictor of the changes in metamorphopsia in daily life. To determine the reproducibility of the M-CHARTS score, another set of 56 eyes with ERM was tested twice on two different days. Results: The postoperative changes in the logarithm of the M-CHARTS score was defined as M2-value. The area under the receiver operating characteristic curve for the M2-value as a predictor of the changes in metamorphopsia in daily life was larger than area under the receiver operating characteristic curve obtained for any other parameter. The optimal cutoff value was -0.4. The 95% limits of agreement between test and retest measurements had a reproducibility of ±0.3 logarithm of the M-CHARTS score. Taking into account not only the reproducibility but also the consistency with the subjective changes, we determined the criterion for clinically significant changes in the M-CHARTS scores as a change of the M2-value by ≥0.4. Conclusion: Evaluating the changes in the M-CHARTS scores in logarithmic form is favorable not only theoretically but also

  15. [A treatment chart adapted to the arch form].

    Bocquet-Moreau, E; Danguy, Ch; Bertrand, J; Danguy, M

    2005-12-01

    Arch wires used in orthodontic treatment must conform to the shape of the dental arches so that in their final positions teeth will be set in a pathway of neuromuscular equilibrium. However, sometimes distortions of the alveoli deform the shape of the arch. In such cases the treatment charts constructed on the actual alveolo-dental relationship will not reflect desired objectives. We believe that the transverse muco-gingival dimension Andrews called the Wala line responds better to therapeutic requirements. Moreover, molar attachments, key elements of a full-banded appliance, are in harmony with it. So the type of chart that the authors propose for use with the Straight Wire technique, one based on the Wala line, will help orthodontists place teeth at the conclusion of orthodontic treatment in the best possible relationships to patients' specific anatomic configurations.

    2006-01-01

    Full Text Available In tropical residual soils most hill slope failures are caused by rainfall. It is therefore important to consider dynamic hydrological conditions when attempting to analyze the stability of residual soil slopes. This paper describes a coupled hydrology/stability model that has been developed to overcome the limitations of the standard method of analysis used to investigate stability of tropical soil slopes. A computational hydrology – limit equilibrium stability analysis model is outlined and examples are provided of the model output capabilities in terms of design charts. Although nowadays most realistic problem should be analyzed by computer and stability charts are mainly used to analyze simple slopes, they can be useful for preliminary analysis and enable the designer to quickly assess the sensitivity of a problem to changes in different input parameters.

    Full Text Available Libraries continue to need to demonstrate their value to stakeholders, and while statistics alone do not represent value, they are an important element. We found ourselves, and our stakeholders, uninspired by our infrequently updated bulleted list of statistics on our website and so set out to create a more dynamic and visually appealing look at our statistics. This article outlines how we used our content management system, Drupal, Open Flash Chart and custom programming to convert library statistics into Flash charts, including how to populate the graphs with dynamic data from external sources. The end result is our Library Statistics Dashboard (http://library.uncw.edu/facts_planning/dashboard that visually demonstrates the use, activity and resources in the library via interactive and visually interesting graphs.

    We consider a production process in which units are produced in a sequential manner. The units can, for example, be manufactured items or services, provided to clients. Each unit produced can be a failure with probability p or a success (non-failure) with probability (1-p). A novel exponentially ...... weighted moving average (EWMA) control chart intended for surveillance of the probability of failure, p, is described. The chart is based on counting the number of non-failures produced between failures in combination with a variance-stabilizing transformation. The distribution function...... are described and a practical example is given. It is demonstrated how the method communicates the current failure probability in a direct and interpretable way, which makes it well suited for surveillance of a great variety of activities in industry or in the service sector such as in hospitals, for example...

    To detect and estimate a shift in either the mean and the deviation or both for the preliminary analysis, the statistical process control (SPC) tool, the control chart based on the likelihood ratio test (LRT), is the most popular method.Sullivan and woodall pointed out the test statistic lrt (n1, n2) is approximately distributed as x2 (2) as the sample size n, n1 and n2 are very large, and the value of n1 = 2, 3,..., n- 2 and that of n2 = n- n1.So it is inevitable that n1 or n2 is not large. In this paper the limit distribution of lrt(n1, n2) for fixed n1 or n2 is figured out, and the exactly analytic formulae for evaluating the expectation and the variance of the limit distribution are also obtained.In addition, the properties of the standardized likelihood ratio statistic slr(n1,n) are discussed in this paper. Although slr(n1, n) contains the most important information, slr(i, n)(i ≠ n1) also contains lots of information. The cumulative sum (CUSUM) control chart can obtain more information in this condition. So we propose two CUSUM control charts based on the likelihood ratio statistics for the preliminary analysis on the individual observations. One focuses on detecting the shifts in location in the historical data and the other is more general in detecting a shift in either the location and the scale or both.Moreover, the simulated results show that the proposed two control charts are, respectively, superior to their competitors not only in the detection of the sustained shifts but also in the detection of some other out-of-control situations considered in this paper.

  7. Semantic-Oriented Sentiment Classification for Chinese Product Reviews: An Experimental Study of Book and Cell Phone Reviews

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Sentiment classification is an automatic opinion classification method to classify the product reviews on web into positive or negative opinions to help consumers or sellers to understand the opinions and evaluations from existing customers. Semantic-oriented approach is one of the recent developments in sentiment classification. Up to now, most research of sentiment classification is on English reviews,and little work has been done on Chinese reviews using sentiment classification. The detailed techniques used in English review cannot be applied directly to Chinese reviews due to the different characteristics between these two languages. This study modified and improved the semantic-oriented approach to a 6-step process for Chinese review, focusing on the modification and improvement on the text segmentation and reference words pairs (RWPs) identification. Two experiments were conducted on book reviews and cell phone reviews. The results show that the performances of the proposed approach are comparable to those of the existing English reviews classification studies.

  12. Economic Statistical Design of integrated X-bar-S control chart with Preventive Maintenance and general failure distribution.

    Caballero Morales, Santiago Omar

    2013-01-01

    The application of Preventive Maintenance (PM) and Statistical Process Control (SPC) are important practices to achieve high product quality, small frequency of failures, and cost reduction in a production process. However there are some points that have not been explored in depth about its joint application. First, most SPC is performed with the X-bar control chart which does not fully consider the variability of the production process. Second, many studies of design of control charts consider just the economic aspect while statistical restrictions must be considered to achieve charts with low probabilities of false detection of failures. Third, the effect of PM on processes with different failure probability distributions has not been studied. Hence, this paper covers these points, presenting the Economic Statistical Design (ESD) of joint X-bar-S control charts with a cost model that integrates PM with general failure distribution. Experiments showed statistically significant reductions in costs when PM is performed on processes with high failure rates and reductions in the sampling frequency of units for testing under SPC.

    Antenatal depression is a known risk factor for postnatal depression; both are common disorders associated with negative impacts on child development. Few studies have followed up women from pregnancy and through the postnatal period to explore how rates of depression change. This review evaluates recent evidence on depression during pregnancy and after childbirth. A search of Embase, PsychINFO, MEDLINE and Cochrane Reviews was carried out to identify longitudinal studies on antenatal and postnatal depression. Studies that measured depression during pregnancy and up to 1 year after childbirth were evaluated against a set of criteria (e.g. less than 50 % attrition). Of the initial 523 studies identified, 16 studies met the final inclusion criteria with a total of 35,419 women. The average rate of antenatal depression across these studies was 17 and 13 % postnatal depression. The longitudinal nature of the studies revealed that on average 39 % of those who experienced antenatal depression went on to have postnatal depression. Similarly, on average, 47 % of those with postnatal depression had also experienced antenatal depression. On average, almost 7 % of women reported significant depressive symptoms in pregnancy that persisted after childbirth. The review provided evidence that rates of depression tend to be higher during pregnancy than in the first year following childbirth. Furthermore, the longitudinal data show that there is much movement between the groups categorised as depressed or not depressed. There is evidence that postnatal depression is often a continuation of existing antenatal depression.

  14. Molecular approaches to bivalve population studies: a review

    2011-12-01

    Full Text Available This paper presents a literature review concerning the importance of molecular approaches in bivalve’s population study. The class Bivalvia counts more than 20,000 species with a wide distribution both in freshwater and marine environment. Given their importance especially in aquaculture as a source of food, they have also a strong economic impact upon human society. This review encompasses best practices in bivalve studies from field sampling to laboratory analyses, addressing questions about molecular methods and tools commonly used by specialized researchers. Molecular tools specifically deals with phylogeography, population genetics, biology, ecology and taxonomy. In all these fields, molecular markers play an important role by completing some unanswered questions such as the role of the bivalves in the ecosystems in relation to anthropogenic and global change issues. Numerous genetic markers were developed for specific problems, thereferore we identify as a major issue the absence of uniform and universally recognized methods. The various sections of the paper emphasize from peer reviewed literature literature which are considered the most useful markers, costs and benefits of different methodology, major gaps of knowledge.in bivalve population studies. By reviewing virtually all genetic markers employed during nearly half a century of bivalve molecular research, in our opinion two are the best option “tools: the mitochondrial COI (cytochrome oxidase subunit I and nuclear ITS2 (internal transcribed spacer 2.

  1. Review of the high conversion-type core study. Review about PWR

    International Nuclear Information System (INIS)

    The study of the high conversion light water reactor was proposed by Edlund in the United States of America in 1975. This theme was aggressively studied in the 1980s. As the reason, the increase of Pu produced from the reprocessing and the delay of practical use of FBR is given. A high converter core can realize comparatively easily by changing core of existing PWR to the tight and short core. In this report, the high converter core study about PWR were reviewed. In the United States of America, the study has already ended but an aggressive study is carried forward in Germany, Japan and so on. In addition to the reactor physics computation, the wide range study of such as critical experiment, conduct experiment of the heat transfer, the fracture behavior of fuel and the reactor-type strategy are carried forward. To investigate these studies is extremely useful in examining a future. (author)

    2013-09-01

    This study analyzed the methodology and applicability of multivariate cumulative sum (MCUSUM) charts for early mastitis and lameness detection. Data used were recorded on the Karkendamm dairy research farm, Germany, between August 2008 and December 2010. Data of 328 and 315 cows in their first 200 d in milk were analyzed for mastitis and lameness detection, respectively. Mastitis as well as lameness was specified according to veterinary treatments. Both diseases were defined as disease blocks. Different disease definitions for mastitis and lameness (2 for mastitis and 3 for lameness) varied solely in the sequence length of the blocks. Only the days before the treatment were included in the disease blocks. Milk electrical conductivity, milk yield, and feeding patterns (feed intake, number of trough visits, and feeding time) were used for the recognition of mastitis. Pedometer activity and feeding patterns were used for lameness detection. To exclude biological trends and obtain independent observations, the values of each input variable were either preprocessed by wavelet filters or a multivariate vector autoregressive model. The residuals generated between the observed and filtered or observed and forecast values, respectively, were then transferred to a classic or self-starting MCUSUM chart. The combination of the 2 preprocessing methods with each of the 2 MCUSUM sum charts resulted in 4 combined monitoring systems. For mastitis as well as lameness detection requiring a block sensitivity of at least 70%, all 4 of the combined monitoring systems used revealed similar results within each of the disease definitions. Specificities of 73 to 80% and error rates of 99.6% were achieved for mastitis. The results for lameness showed that the definitions used obtained specificities of up to 81% and error rates of 99.1%. The results indicate that the monitoring systems with these study characteristics have appealing features for mastitis and lameness detection. However, they

    Science.gov (United States)

    Pela, O A; Ebie, J C

    1982-01-01

    This paper reviews the available literature on the epidemiology of drug abuse in Nigeria. Depending on the definition used, substances which are abused include antibiotics, antidiarrhoeals, laxatives, pain-relieving drugs, sedatives, amphetamines and cannabis. This review is, however, limited to studies on substances which alter behaviour or mood. These drugs include cannabis, sedative-hypnotics, amphetamines and alcohol. For some classes of drugs there has been a noticeable shift in patterns of drug abuse, for example, from abuse of methaqualone to barbiturates. The abuse of volatile solvents and other substances has also been noted. The review shows that there is no age limit among drug abusers. Studies on the influence of social class have been contradictory. Factors which indicate a predisposition to initial drug use have been similar to those reported in other cultures. Although the studies agreed on the classes of drugs abused and the changing patterns of drug abuse, there has been no uniform reporting system. This situation is attributed to financial constraints. Large-scale surveys which should incorporate most of the core items in any epidemiological study on substance abuse have been suggested. PMID:6985029

  5. Chart Venture Partners' perspective on dual-use CBRNE technologies

    Science.gov (United States)

    Van Nice, C. S.; Gardner, P. J.

    2008-04-01

    Chart Venture Partners' (CVP) approach to investing in Chemical, Biological, Radiological, Nuclear, and Explosives (CBRNE) detection technologies can be best understood in the context of the unique partnership between the firm's two founding institutions. CVP was founded as a partnership between the Chart Group, a New York-based merchant banking and venture capital boutique, and InSitech Incorporated, a 501(c)(3) non-profit commercial partnership intermediary for the U.S. Army's Armament Research Development and Engineering Center (ARDEC) at Picatinny Arsenal in New Jersey. The partnership between Chart Group and Insitech has yielded a new investment model. Unlike most venture funds, CVP operates with a singular focus on early-stage defense and security technologies, with the important caveat that everything we invest in must also have dual-use application in large-scale commercial markets. CVP believes that early-stage CBRNE companies require five qualities to be viable investment candidates and successful start-up companies: Great Science, Strong IP Positions, Recognized Scientific Champions, Identified Dual-Use Market Pull, and "Real World" Technical Performance Data. When earlystage CBRNE companies decide to seek venture capital and pursue higher growth dual-use business models, we often find that certain issues arise that are not always fully contemplated at the outset, and that can create gaps between what the start-up companies are offering to investors and what those investors are seeking from their potential portfolio companies. These same issues can have significant positive or negative impact on shareholder value over time, depending on how they are managed. Specifically, startups should consider carefully their strategies related to business development, market positioning, government funding, and investment syndicate formation.

    2006-01-01

    The number of cost-of-illness (COI) studies has expanded considerably over time. One outcome of this growth is that the reported COI estimates are inconsistent across studies, thereby raising concerns over the validity of the estimates and methods. Several factors have been identified in the literature as reasons for the observed variation in COI estimates. To date, the variation in the methods used to calculate costs has not been examined in great detail even though the variations in methods are a major driver of variation in COI estimates. The objective of this review was to document the variation in the methodologies employed in COI studies and to highlight the benefits and limitations of these methods. The review of COI studies was implemented following a four-step procedure: (i) a structured literature search of MEDLINE, JSTOR and EconLit; (ii) a review of abstracts using pre-defined inclusion and exclusion criteria; (iii) a full-text review using pre-defined inclusion and exclusion criteria; and (iv) classification of articles according to the methods used to calculate costs. This review identified four COI estimation methods (Sum_All Medical, Sum_Diagnosis Specific, Matched Control and Regression) that were used in categorising articles. Also, six components of direct medical costs and five components of indirect/non-medical costs were identified and used in categorising articles.365 full-length articles were reflected in the current review following the structured literature search. The top five cost components were emergency room/inpatient hospital costs, outpatient physician costs, drug costs, productivity losses and laboratory costs. The dominant method, Sum_Diagnosis Specific, was a total costing approach that restricted the summation of medical expenditures to those related to a diagnosis of the disease of interest. There was considerable variation in the methods used within disease subcategories. In several disease subcategories (e.g. asthma, dementia

    Full Text Available Abstract Background Few studies discuss the indicators used to assess the effect on cost containment in healthcare across hospitals in a single-payer national healthcare system with constrained medical resources. We present the intraclass correlation coefficient (ICC to assess how well Taiwan constrained hospital-provided medical services in such a system. Methods A custom Excel-VBA routine to record the distances of standard deviations (SDs from the central line (the mean over the previous 12 months of a control chart was used to construct and scale annual medical expenditures sequentially from 2000 to 2009 for 421 hospitals in Taiwan to generate the ICC. The ICC was then used to evaluate Taiwan’s year-based convergent power to remain unchanged in hospital-provided constrained medical services. A bubble chart of SDs for a specific month was generated to present the effects of using control charts in a national healthcare system. Results ICCs were generated for Taiwan’s year-based convergent power to constrain its medical services from 2000 to 2009. All hospital groups showed a gradually well-controlled supply of services that decreased from 0.772 to 0.415. The bubble chart identified outlier hospitals that required investigation of possible excessive reimbursements in a specific time period. Conclusion We recommend using the ICC to annually assess a nation’s year-based convergent power to constrain medical services across hospitals. Using sequential control charts to regularly monitor hospital reimbursements is required to achieve financial control in a single-payer nationwide healthcare system.

    Athletes anticipatorily set and continuously adjust pacing strategies before and during events to produce optimal performance. Self-regulation ensures maximal effort is exerted in correspondence with the end point of exercise, while preventing physiological changes that are detrimental and disruptive to homeostatic control. The integration of feedforward and feedback information, together with the proposed brain's performance modifiers is said to be fundamental to this anticipatory and continuous regulation of exercise. The manipulation of central, regulatory internal and external stimuli has been a key focus within deception research, attempting to influence the self-regulation of exercise and induce improvements in performance. Methods of manipulating performance modifiers such as unknown task end point, deceived duration or intensity feedback, self-belief, or previous experience create a challenge within research, as although they contextualize theoretical propositions, there are few ecological and practical approaches which integrate theory with practice. In addition, the different methods and measures demonstrated in manipulation studies have produced inconsistent results. This review examines and critically evaluates the current methods of how specific centrally controlled performance modifiers have been manipulated, within previous deception studies. From the 31 studies reviewed, 10 reported positive effects on performance, encouraging future investigations to explore the mechanisms responsible for influencing pacing and consequently how deceptive approaches can further facilitate performance. The review acts to discuss the use of expectation manipulation not only to examine which methods of deception are successful in facilitating performance but also to understand further the key components used in the regulation of exercise and performance.

  14. Bronze age cosmology and rock art images. Solar ships, deer and charts

    Dimitriadis, G.

    Bronze Age societies were technologically complex. The impressive production of metal artefacts embodies clearly their astronomical culture and cosmological viewpoint. Same ascertainment is valid also for rock art. In fact, around the European landscape were discovered several cliffs engraved with solar ships, deer and charts. How one could be interpret them? Which is the hidden mentality? From the end of 3rd millennium-early 2nd millennium B. C. deep technological transformations are made by metals. New inventions such metal extraction for weapon production, horse pulling chariot used for war and the bull pulling one used for trade may shorten the culture and material distances between Central Europe and South Mediterranean area. Indeed, taphonomic studies indicate a specific modification of the human body mortuary traditional disposition (orientated to significant astronomical targets) below a substantial transformation of mortuary apparatus with spot evidence of weapons (halberds, swords, knifes) and ornaments (double spiral, lunar shape pectorals). The famous Trundhold Solar chart, the 2nd millennium terracotta chart form Dupljaja, the solar boats petroglyph in Bohusland and the horse rider carved on Philippi's cliffs were conceived by the same mentality: communion with the divinity. Culture expressions as communicate manifestation attested in rock art were produced by the same mentality presented in Bronze Age art-crafts such as, 1. Culture epidemiologic patterns dispersion took place through out iconographic motives, and, 2. Animals can play a double face function inside an analogical-mythological system: a. animal-reflex; b. animal-agent. The question is: Could such petroglyphs help us to "read" archaeoastronomical properly in an archaeological site?

    Chang, X; Yang, D [Washington University in St Louis, St Louis, MO (United States)

    2015-06-15

    Purpose: A software tool was developed in this study to perform automatic weekly physics chart check on the patient data in ARIA. The tool accesses the electronic patient data directly from ARIA server and checks the accuracy of treatment deliveries, and generates reports which summarize the delivery history and highlight the errors. Methods: The tool has four modules. 1) The database interface is designed to directly access treatment delivery data from the ARIA database before reorganizing the data into the patient chart tree (PCT). 2) PCT is a core data structure designed to store and organize the data in logical hierarchies, and to be passed among functions. 3) The treatment data check module analyzes the organized data in PCT and stores the checking results into PCT. 4) Report generation module generates reports containing the treatment delivery summary, chart checking results and plots of daily treatment setup parameters (couch table positions, shifts of image guidance). The errors that are found by the tool are highlighted with colors. Results: The weekly check tool has been implemented in MATLAB and clinically tested at two major cancer centers. Javascript, cascading style sheets (CSS) and dynamic HTML were employed to create the user-interactive reports. It takes 0.06 second to search the delivery records of one beam with PCT and compare the delivery records with beam plan. The reports, saved in the HTML files on shared network folder, can be accessed by web browser on computers and mobile devices. Conclusion: The presented weekly check tool is useful to check the electronic patient treatment data in Varian ARIA system. It could be more efficient and reliable than the manually check by physicists. The work was partially supported by a research grant from Varian Medical System.

    Pasi J Eskola

    Full Text Available OBJECTIVE: Low back pain is associated with lumbar disc degeneration, which is mainly due to genetic predisposition. The objective of this study was to perform a systematic review to evaluate genetic association studies in lumbar disc degeneration as defined on magnetic resonance imaging (MRI in humans. METHODS: A systematic literature search was conducted in MEDLINE, MEDLINE In-Process, SCOPUS, ISI Web of Science, The Genetic Association Database and The Human Genome Epidemiology Network for information published between 1990-2011 addressing genes and lumbar disc degeneration. Two investigators independently identified studies to determine inclusion, after which they performed data extraction and analysis. The level of cumulative genetic association evidence was analyzed according to The HuGENet Working Group guidelines. RESULTS: Fifty-two studies were included for review. Forty-eight studies reported at least one positive association between a genetic marker and lumbar disc degeneration. The phenotype definition of lumbar disc degeneration was highly variable between the studies and replications were inconsistent. Most of the associations presented with a weak level of evidence. The level of evidence was moderate for ASPN (D-repeat, COL11A1 (rs1676486, GDF5 (rs143383, SKT (rs16924573, THBS2 (rs9406328 and MMP9 (rs17576. CONCLUSIONS: Based on this first extensive systematic review on the topic, the credibility of reported genetic associations is mostly weak. Clear definition of lumbar disc degeneration phenotypes and large population-based cohorts are needed. An international consortium is needed to standardize genetic association studies in relation to disc degeneration.

    Belize trained psychiatric nurse practitioners (PNPs) in the early 1990s to provide mental health services throughout the country. Despite overwhelming success, the program is limited by lack of monitoring, evaluation, and surveillance. To promote quality assurance, we developed a chart audit tool to monitor mental healthcare delivery compliance for initial psychiatric assessment notes completed by PNPs. After reviewing the Belize Health Information System electronic medical record system, we developed a clinical audit tool to capture 20 essential components for initial assessment clinical notes. The audit tool was then piloted for initial assessment notes completed during July through September of 2013. One hundred and thirty-four initial psychiatric interviews were audited. The average chart score among all PNPs was 9.57, ranging from 3 to 15. Twenty-three charts-or 17.2%-had a score of 14 or higher and met a 70% compliance benchmark goal. Among indicators most frequently omitted included labs ordered and named (15.7%) and psychiatric diagnosis (21.6%). Explicit statement of medications initiated with dose and frequency occurred in 47.0% of charts. Our findings provide direction for training and improvement, such as emphasizing the importance of naming labs ordered, medications and doses prescribed, and psychiatric diagnoses in initial assessment clinical notes. We hope this initial assessment helps enhance mental health delivery compliance by prompting creation of BHIS templates, development of audits tools for revisit follow-up visits, and establishment of corrective actions for low-scoring practitioners. These efforts may serve as a model for implementing quality assurance programming in other low resource settings. PMID:25829167

    The influence of space weather has already been an important part of our modern society. A chart with key concepts and objects in space weather is needed for space weather forecast. In this work, we search space weather liter- atures during the past forty years and investigate a variety of solar data sets, which including our own data observed by the vector magnetic field telescope and the Hα telescope at Wenquan and Shidao stations of National Center for Space Weather. Based on the literatures and data, we design the solar synoptic chart (SSC) that covers main objects of solar activities and contains images from different heights and temperatures of solar atmosphere. The SSC includes the information of active regions, coronal holes, filaments/prominences, flares and coronal mass ejections, and reveals magnetic structures from cooler photosphere to hotter corona. We use the SSC method to analyze the condition of the Sun and give two typical examples of the SSC. The result shows that the SSC is timely, comprehensive, concise and easy to understand, and it meets the needs of space weather forecast and can help improving the public education of space weather.

  1. Systematic Review of Measles and Rubella Serology Studies.

    2016-07-01

    Serological tests provide information about individual immunity from historical infection or immunization. Cross-sectional serological studies provide data about the age- and sex-specific immunity levels for individuals in the studied population, and these data can provide a point of comparison for the results of transmission models. In the context of developing an integrated model for measles and rubella transmission, we reviewed the existing measles and rubella literature to identify the results of national serological studies that provided cross-sectional estimates of population immunity at the time of data collection. We systematically searched PubMed, the Science Citation Index, and references we identified from relevant articles published in English. We extracted serological data for comparison to transmission model outputs. For rubella, serological studies of women of child-bearing age provide information about the potential risks of infants born with congenital rubella syndrome. Serological studies also document the loss of maternal antibodies, which occurs at different rates for the different viruses and according to the nature of the induced immunity (i.e., infection or vaccine). The serological evidence remains limited for some areas, with studies from developed countries representing a disproportionate part of the evidence. The collection and review of serological evidence can help program managers identify immunity gaps in the population, which may help them better understand the characteristics of individuals within their populations who may participate in transmission and manage risks.

    Studies that treat creativity as operant behavior were critically reviewed. Of the twenty studies, most met minimal requirements for methodological adequacy; all provided at least some evidence for increased creative responding. Major difficulties involved potential confounds between instructions and contingencies, lack of an independent record of the training interaction, lack of social validation data, and very limited evidence for generalization. Several issues were discussed: problems in the behavioral definition of creativity, objections to the use of contingent reinforcement, and the need for empirical analysis of the creative process.

    Full Text Available A model for predicting the friction required by a palm frond broom peeling machine for effective peeling of palm leaf to broom bristle and a chart for selecting the best abrasive material for this machine’s peeling operation were developed in this study using mechanistic modeling method. The model quantified the relationship between the coefficient of friction and other operational parameters of this machine while the abrasives selection chart constitutes a plot of this measured friction parameter against the abrasive materials used in palm frond broom peeling machine fabrication. The values of the coefficient of friction of palm leaf on different abrasive materials used in this plot were determined from experimental study of the effect of moisture content level of naturally withered palm leaves (uninfluenced by external forces on their coefficient of friction with the abrasives. Results revealed the average moisture content of palm leaf this machine can peel effectively as 6.96% and also that the roughest among the abrasives that approximate the coefficient of friction for a specific design of this peeling machine gives maximum peeling efficiency. Thus, the roughest among the abrasive materials that approximate the coefficient of friction for a specific design of this machine should be selected and used for its fabrication and operation.

    Full Text Available Context Alcohol consumption has escalated rapidly in many countries over the past decade. Evidence suggests a correlation between alcohol use and cognitive decline. We have systematically reviewed the concept and controversies, epidemiology, nosology, neuropathology and neurobiology, neuropsychology and management updates of alcohol-related dementia (ARD in this paper. Evidence Acquisition We retrieved papers for this review by searching the PubMed database for terms “alcohol and dementia”, “alcohol and cognitive impairment”, and “alcohol and wernicke-korsakoff” mentioned in the title of the published papers. A total of 131 studies showed up. Appropriate studies were shortlisted and included (n = 72. Cross-references if relevant were considered from the selected studies. Eligible articles were fully read by the authors and the results were compiled. Results The prolonged and excessive use of alcohol may lead to structural and functional brain damage, leading to ARD. The cognitive deficits are most frequently observed in domains of visuospatial functions, memory and executive tasks, with a potential of partial recovery if abstinence is maintained. However, there are doubts regarding the etiopathogenesis, nosological status, prevalence and diagnostic criteria for ARD, due to difficulty in assessment and various confounding factors. Conclusions With growing cohort of young and middle-aged people, there is a probable risk of upsurge of ARD. Presently, there are dilemmas over the diagnosis of independent ARD. Thus, there is a need to develop evidence-based guidelines for diagnosis and management of ARD through further systematic studies.

    Full Text Available Our understanding of the pathogenesis of endocrine disorders increase rapidly by genetic studies at the molecular level. Common endocrine disorders such as diabetes mellitus, obesity, osteoporosis, dyslipidemia and cancer follow the multifactorial model in the genetic aspect. This review tries to clarify the approach in molecular studies of such diseases for clinicians in different specialties. How to evaluate a possible association between a single nucleotide polymorphism and an endocrinopathy or its complication is the main concern of this review. Two approaches for gene mapping will be discussed as well as main challenges regarding each approach. All such genetic studies ideally include some test of the association between genome sequence variation and the phenotype of interest such as the trait itself, the presence of a given complication, or measures of some endocrinopathy-related intermediate trait. Despite different advances in this analysis, there are major concerns regarding the overall performance and robustness of genetic association studies. By using powerful new high-throughput methods, further insights to molecular basis of such endocrine disorders can be expected. Close correlation between geneticists and clinicians can effectively bridge between basic sciences and clinical investigations.

    Although stability charts suggested by Hoek and Bray on the basis of Mohr-Coulomb criterion are used for rock slopes, but complete and precise recognition is required for distinguishing cohesive strength and Mohr-Coulomb equivalent internal friction angle for rock mass. The paper by Lia et al. [6] is the only one that introduced rock slope charts according to Hoek-Brown failure criterion. In this paper, at first, this type of charts is introduced. Then, Mohr-Coulomb failure criterion charts [2] are compared and validated with Hoek-Brown failure criterion ones [6]. Next, Bishop method utilizing Slide software is compared with Hoek-Brown failure criterion stability charts. Average standard deviation (ASD), root mean square error (RMSE) and variance account for (VAF) were used for the comparison. According to the results, because of high distribution and very low correlation among the comparisons, Hoek-Brown failure crite-rion charts are not efficient.

    Jamshidieini, Bahman; Fazaee, Reza

    2016-05-01

    Distribution network components connect machines and other loads to electrical sources. If resistance or current of any component is more than specified range, its temperature may exceed the operational limit which can cause major problems. Therefore, these defects should be found and eliminated according to their severity. Although infra-red cameras have been used for inspection of electrical components, maintenance prioritization of distribution cubicles is mostly based on personal perception and lack of training data prevents engineers from developing image processing methods. New research on the spatial control chart encouraged us to use statistical approaches instead of the pattern recognition for the image processing. In the present study, a new scanning pattern which can tolerate heavy autocorrelation among adjacent pixels within infra-red image was developed and for the first time combination of kernel smoothing, spatial control charts and local robust regression were used for finding defects within heterogeneous infra-red images of old distribution cubicles. This method does not need training data and this advantage is crucially important when the training data is not available.

  18. Innovation in Stroke Care Quality: NIH Stroke Scale Change and Shewhart Charts.

    Dobbs, Michael R; Krishnamohan, Prashanth; Jicha, Gregory; Cohen, Amy P

    2015-01-01

    Stroke care, admission through discharge, is a process that should lead to symptomatic improvement. Improvement or decline in conditions of patients with acute stroke during hospitalization can be measured by the National Institutes of Health Stroke Scale (NIH Stroke Scale or NIHSS) at both admission and discharge and may indicate the overall quality of acute stroke care for a patient and the stability of care in the system. Shewhart control charts were analyzed for 98 patients with stroke admissions in a random sample at a tertiary care stroke center to determine the feasibility of examining the NIHSS score change to detect statistical control or identify excess variance in outcomes. The study sample showed a mean improvement of 1.33 points from admission to discharge on the NIHSS. Three statistical outliers were found. Excess statistical variation clustered within a specific stroke team's tenure suggested a need for targeted education and examination for process redesign. Using the NIHSS and the Shewhart control charts identified a systematic process flaw that could be targeted to improve stroke outcomes and move the delivery system toward statistical control.

    Full Text Available Objective: The healthcare chart is becoming ever more complex, serving clinicians, patients, third party payers, regulators, and even medicolegal parties. The purpose of this study was to identify our emergency medicine (EM resident and attending physicians’ current knowledge and attitudes about billing and documentation practices. We hypothesized that resident and attending physicians would identify billing and documentation as an area in which residents need further education.Methods: We gave a 15-question Likert survey to resident and attending physicians regarding charting practices, knowledge of billing and documentation, and opinions regarding need for further education.Results: We achieved a 100% response rate, with 47% (16/34 of resident physicians disagreeing or strongly disagreeing that they have adequate training in billing and documentation, while 91% (31/34 of residents and 95% (21/22 of attending physicians identified this skill as important to a resident’s future practice. Eighty-two percent (28/34 of resident physicians and 100% of attending physicians recommended further education for residents.Conclusion: Residents in this academic EM department identified a need for further education in billing and documentation practices.

    Growth monitoring of apparently healthy children aims at early detection of serious underlying disorders. However, existing growth-monitoring practices are mainly based on suboptimal methods, which can result in delayed diagnosis of severe diseases and inappropriate referrals. We did a systematic review to address two key and interconnected questions underlying growth monitoring: which conditions should be targeted, and how should abnormal growth be defined? We systematically searched for studies reporting algorithms for growth monitoring in children and studies comparing the performance of new WHO growth charts with that of other growth charts. Among 1556 identified citations, 69 met the inclusion criteria. Six target conditions have mainly been studied: Turner syndrome, coeliac disease, cystic fibrosis, growth hormone deficiency, renal tubular acidosis, and small for gestational age with no catch-up after 2 or 3 years. Seven algorithms to define abnormal growth have been proposed in the past 20 years, but their level of validation is low, and their overall sensitivities and specificities vary substantially; however, the Grote and Saari clinical decision rules seem the most promising. Two studies reported that WHO growth charts had poorer performance compared with other existing growth charts for early detection of target conditions. Available data suggest a large gap between the widespread implementation of growth monitoring and its level of evidence or the clinical implications of early detection of serious disorders in children. Further investigations are needed to standardise the practice of growth monitoring, with a consensus on a few priority target conditions and with internationally validated clinical decision rules to define abnormal growth, including the selection of appropriate growth charts.

    Full Text Available Abstract Background Although abortion or termination of pregnancy (TOP has become an increasingly normalized component of women's health care over the past forty years, insufficient attention has been paid to women's experiences of surgical or medical methods of TOP. Objective To undertake a narrative review of qualitative studies of women's experiences of TOP and their perspectives on surgical or medical methods. Methods Keyword searches of Medline, CINAHL, ISI, and IBSS databases. Manual searches of other relevant journals and reference lists of primary articles. Results Qualitative studies (n = 18 on women's experiences of abortion were identified. Analysis of the results of studies reviewed revealed three main themes: experiential factors that promote or inhibit the choice to seek TOP; experiences of TOP; and experiential aspects of the environment in which TOP takes place. Conclusion Women's choices about TOP are mainly pragmatic ones that are related to negotiating finite personal and family and emotional resources. Women who are well informed and supported in their choices experience good psychosocial outcomes from TOP. Home TOP using mifepristone appears attractive to women who are concerned about professionals' negative attitudes and lack of privacy in formal healthcare settings but also leads to concerns about management and safety.

    To the first order, eustatic charts are in accord with our understanding of the geodynamic processes that control sea level. By extrapolation, second-order features are also thought to obey to the same rules, and are thus often taken for granted. But this assumption may be jeopardized by a close examination of a characteristic example. The Permo-Triassic period is characteristic for both its purported eustatic signal and its geodynamic and climatic setting are well defined and contrasted. Both the fragmentation of the Pangean supercontinent and the late Paleozoic melting of ice sheets argue for a rise of the eustatic sea level (ESL) whereas eustatic charts show the opposite. Here we review the possible mechanisms that could explain the apparent sea level low, and find that some of them do lower the ESL while others instead only modify the referential, either uplifting continents or tilting the margins where the control points are located. In the first category, we find that (i) dynamic deflections of the Earth surface above subduction zones and their location with respect to continents primarily control absolute sea level while the Pangean supercontinent forms and breaks up, (ii) endorheism that ubiquitously developed at the time of Pangean aggregation also contributed to lowering the ESL by storing water out of the oceanic reservoir. In the second category, we show that (i) the thermal uplift associated to supercontinental insulation and (ii) the dynamic uplift associated with the emplacement of a superplume both give rates of change in the range of long-term changes of ESL. We also show that (iii) the dynamic tilting of continental margins not only produces apparent sea level changes, but also modifies the absolute sea level, which in turn may end up in the paradoxical situation wherein fingerprints of ESL drop are found in the geological record whereas ESL is actually rising. We conclude that the establishment of second to third order absolute sea level changes

    Illumination estimation is the main step in color constancy processing, also an important prerequisite for digital color image reproduction and many computer vision applications. In this paper, a method for estimating illuminant spectrum is investigated using a digital color camera and a color chart under the situation when the spectral reflectance of the chart is known. The method is based on measuring CIEXYZ of the chart using the camera. The first step of the method is to gain camera's color correction matrix and gamma values by taking a photo of the chart under a standard illuminant. The second step is to take a photo of the chart under an estimated illuminant, and the camera's inherent RGB values are converted to the standard sRGB values and further converted to CIEXYZ of the chart. Based on measured CIEXYZ and known spectral reflectance of the chart, the spectral power distribution (SPD) of the illuminant is estimated using the Wiener estimation and smoothing estimation. To evaluate the performance of the method quantitatively, the goodnessfitting coefficient (GFC) was used to measure the spectral match and the CIELAB color difference metric was used to evaluate the color match between color patches under the estimated and actual SPDs. The simulated experiment was carried to estimate CIE standard illuminant D50 and C using X-rite ColorChecker 24-color chart, the actual experiment was carried to estimate daylight and illuminant A using two consumergrade cameras and the chart, and the experiment results verified feasible of the investigated method.

  4. A Critical Review of Some Ecological Studies on Scientific Journals

    Science.gov (United States)

    Yamazaki, Shigeaki

    There have been hot discussions about the number and the rate of growth of scientific journals. The purpose of this review is intended to provide a critical assessment of those ecological studies on scientific journals. In 1961, Price presented his famous graph curve, and noted that rate of growth of journals had been fairly consisted at 5 per cent annum for nearly 300 years. But Price's graph curve has some primary error, and the author suggest to examine carefully his study. There is another problem that the loose definition of scientific journals is used. The author try to give a clear definition on the term ‘scientific journals’, and try to reestimate historically the growth rate in numbers of current scientific journals, referring several reliable studies previously conducted. The Author's estimation is about 1.85 per cent a year from the last of 18 century.

    Full Text Available Introduction. This paper focuses on the application of Magnetic Resonance Spectroscopy (MRS to the study of Major Depressive Disorder (MDD in children and adolescents. Method. A literature search using the National Institutes of Health's PubMed database was conducted to identify indexed peer-reviewed MRS studies in pediatric patients with MDD. Results. The literature search yielded 18 articles reporting original MRS data in pediatric MDD. Neurochemical alterations in Choline, Glutamate, and N-Acetyl Aspartate are associated with pediatric MDD, suggesting pathophysiologic continuity with adult MDD. Conclusions. The MRS literature in pediatric MDD is modest but growing. In studies that are methodologically comparable, the results have been consistent. Because it offers a noninvasive and repeatable measurement of relevant in vivo brain chemistry, MRS has the potential to provide insights into the pathophysiology of MDD as well as the mediators and moderators of treatment response.

    Intrusion detection systems have a highly significant role in securing computer networks and information systems. To assure the reliability and quality of computer networks and information systems, it is highly desirable to develop techniques that detect intrusions into information systems. We put forward the concept of statistical process control (SPC) in computer networks and information systems intrusions. In this article we propose exponentially weighted moving average (EWMA) type quality monitoring scheme. Our proposed scheme has only one parameter which differentiates it from the past versions. We construct the control limits for the proposed scheme and investigate their effectiveness. We provide an industrial example for the sake of clarity for practitioner. We give comparison of the proposed scheme with EWMA schemes and p chart; finally we provide some recommendations for the future work.

Of interest is Figure 28, showing the Club of Rome's model of the earth in terms of resource consumption, food, money, people, pollution, etc. A computer was asked to extend recent history into the future and results indicate a collapse of the industrialized system towards an agrarian culture around the year 2025. It is noted that the model did not consider technological initiative or man's willingness to change lifestyles. The final (33) schematic is a guesstimate of noticeable impact timescales, indicating when research projects on transition or ultimate energy sources at LASL might be expected to yield impact. (MCW)

    Hundreds of satellites have been launched to date. Some have operated extremely well and others have not. In order to learn from past operating experiences, a study was conducted to determine the conditions under which space mechanisms (mechanically moving components) have previously worked or failed. The study consisted of an extensive literature review that included both government contractor reports and technical journals, communication and visits (when necessary) to the various NASA and DOD centers and their designated contractors (this included contact with project managers of current and prior NASA satellite programs as well as their industry counterparts), requests for unpublished information to NASA and industry, and a mail survey designed to acquire specific mechanism experience. The information obtained has been organized into two volumes. Volume 1 provides a summary of the lesson learned, the results of a needs analysis, responses to the mail survey, a listing of experts, a description of some available facilities, and a compilation of references. Volume 2 contains a compilation of the literature review synopsis.

    This study effort was required as a preliminary step prior to initiation of field measurements of atmospheric dispersion in coastal regions. The Nuclear Regulatory Commission (NRC) is in the process of planning an extensive field measurement program to generate data which will serve as improved data bases for licensing decisions, confirmation of regulations, standards, and guides, and for site characterizations. The study being reported here is an effort directed to obtaining as much information as is possible from existing studies that is relevant toward NRC's objectives. For this study, reports covering research and meteorological measurements conducted for industrial purposes, utility needs, military objectives, and academic studies were obtained and critically reviewed in light of NRC's current data needs. This report provides an interpretation of the extent of existing usable information, an indication of the potential for tailoring existing research toward current NRC information needs, and recommendations for several follow-on studies which could provide valuable additional information through reanalysis of the data. Recommendations are also offered regarding new measurement programs. Emphasis is placed on the identification and acquisition of data from atmospheric tracer studies conducted in coastal regions. A total of 225 references were identified which deal with the coastal atmosphere, including meteorological and tracer measurement programs, theoretical descriptions of the relevant processes, and dispersion models.

  12. Changes in serum and salivary amylase during radiotherapy for head and neck cancer; A comparison of conventionally fractionated radiotherapy with CHART

    The changes in serum amylase that occur when radiotherapy is given in the treatment of head and neck cancer has been studied in 41 patients, 29 treated by CHART and 12 by conventionally fractionated radiotherapy. The peak rise in serum amylase following the start of treatment is seen earlier and is greater in the patients receiving continuous hyperfractionated accelerated radiotherapy (CHART). The serum amylase returns to normal earlier in the CHART patients so that the area under the curve is the same for both groups. The difference probably reflects the more rapid delivery of treatment to the patients receiving CHART. A close correlation between the peak rise in serum amylase and the amount of parotid tissue in the treatment volume is demonstrated. For six patients the total amount of amylase secreted by the parotid gland during CHART was measured and found to decline rapidly within a few days of the start of radiotherapy. The rise in serum amylase that results from the irradiation of salivary tissue provides a unique biochemical measure of an early radiation effect in a normal tissue. This probably reflects the interphase cell death of serous salivary cells. Although these immediate changes are of considerable interest they may not relate to the late effects of radiation on salivary gland function. (author). 13 refs.; 4 figs.

    Full Text Available Background World Health Organization/International Society of Hypertension (WHO/ISH charts have been employed to predict the risk of cardiovascular outcome in heterogeneous settings. The aim of this research is to assess the prevalence of Cardiovascular Disease (CVD risk factors and to estimate the cardiovascular risk among adults aged >40 years, utilizing the risk charts alone, and by the addition of other parameters. Methods A cross-sectional study was performed in two of the villages availing health services of a medical college. Overall 570 subjects completed the assessment. The desired information was obtained using a pretested questionnaire and participants were also subjected to anthropometric measurements and laboratory investigations. The WHO/ISH risk prediction charts for the South-East Asian region was used to assess the cardiovascular risk among the study participants. Results The study covered 570 adults aged above 40 years. The mean age of the subjects was 54.2 (±11.1 years and 53.3% subjects were women. Seventeen percent of the participants had moderate to high risk for the occurrence of cardiovascular events by using WHO/ISH risk prediction charts. In addition, CVD risk factors like smoking, alcohol, low High-Density Lipoprotein (HDL cholesterol were found in 32%, 53%, 56.3%, and 61.5% study participants, respectively. Conclusion Categorizing people as low (20% risk is one of the crucial steps to mitigate the magnitude of cardiovascular fatal/non-fatal outcome. This cross-sectional study indicates that there is a high burden of CVD risk in the rural Pondicherry as assessed by WHO/ISH risk prediction charts. Use of WHO/ISH charts is easy and inexpensive screening tool in predicting the cardiovascular event.

    Full Text Available In combination with whole report and partial report tasks, the Theory of Visual Attention (TVA can be used to estimate individual differences in five basic attentional parameters: The visual processing speed, the storage capacity of visual short-term memory, the perceptual threshold, the efficiency of top-down selectivity, and the spatial bias of attentional weighting. TVA-based assessment has been used in about 30 studies to investigate attentional deficits in a range of neurological and psychiatric conditions: (a neglect and simultanagnosia, (b reading disturbances, (c aging and neurodegenerative diseases, and most recently (d neurodevelopmental disorders. The article introduces TVA based assessment, discusses its methodology and psychometric properties, and reviews the progress made in each of the four research fields. The empirical results demonstrate the general usefulness of TVA-based assessment for many types of clinical neuropsychological research. The method’s most important qualities are cognitive specificity and theoretical grounding, but it is also characterized by good reliability and sensitivity to minor deficits. The review concludes by pointing to promising new areas for clinical TVA-based research.

  8. Resveratrol: A review of preclinical studies for human cancer prevention

    International Nuclear Information System (INIS)

    The search for novel and effective cancer chemopreventive agents has led to the identification of various naturally occurring compounds one of which is resveratrol (trans-3,4',5-trihydroxystilbene), a phytoalexin derived from the skin of grapes and other fruits. Resveratrol is known to have potent anti-inflammatory and antioxidant effects and to inhibit platelet aggregation and the growth of a variety of cancer cells. Its potential chemopreventive and chemotherapeutic activities have been demonstrated in all three stages of carcinogenesis (initiation, promotion, and progression), in both chemically and UVB-induced skin carcinogenesis in mice, as well as in various murine models of human cancers. Evidence from numerous in vitro and in vivo studies has confirmed its ability to modulate various targets and signaling pathways. This review discusses the current preclinical and mechanistic data available and assesses resveratrol's anticancer effects to support its potential as an anticancer agent in human populations

    Full Text Available The protective structures required for performing critical operations are vulnerable to the blast and shock loads of advanced weapons. A blast valve is an important component of such structures for ventilation during normal conditions and for protection from blast/ shock during explosion. In this paper, various aspects of blast valve design and related studies are briefly reviewed. The concept and effects of blast wave, blast impact, numerical modelling and deformation of circular plate (one of the critical components of blast valve have been discussed. The merits and demerits of sensing mechanisms viz. remote and direct sensing are discussed. The leakage of blast pressure during finite closing period of the valve (one of the critical problems and the shock tube as a major experimental facility for testing of blast valves are briefly discussed.

    Full Text Available Web 2.0 technologies have attracted an increasing number of active online writers and viewers. A deeper understanding of when customers will review and what motivates them to write online reviews is of both theoretical and practical significance. In this paper, we present a novel methodological framework, which consists of theoretical modeling and text-mining technologies, to study the relationships among customers’ review promptness, their review opinions, and their review motivations. We first study customers’ online “purchase-review” behavior dynamics; then, we introduce the LDA method to mine customers’ opinion from their review text; finally, we propose a theoretical model to explore some motivations for those people publishing review online. The analytical and experimental results with real data from a Chinese B2C website demonstrate that the behavior dynamics of customers’ online review are influenced by the multidimensional motivations, and some of them can be observed from their review behaviors, such as review promptness.

    Balata, Patricia Maria Mendes

    2014-01-01

    Full Text Available Introduction: Surface electromyography has been used to assess the extrinsic laryngeal muscles during chewing and swallowing, but there have been few studies assessing these muscles during phonation. Objective: To investigate the current state of knowledge regarding the use of surface electromyography for evaluation of the electrical activity of the extrinsic muscles of the larynx during phonation by means of an integrative review. Method: We searched for articles and other papers in the PubMed, Medline/Bireme, and Scielo databases that were published between 1980 and 2012, by using the following descriptors: surface electromyography and voice, surface electromyography and phonation, and surface electromyography and dysphonia. The articles were selectedon the basis ofinclusion and exclusion criteria. Data Synthesis: This was carried out with a cross critical matrix. We selected 27 papers,i.e., 24 articles and 3 theses. The studies differed methodologically with regards to sample size and investigation techniques, making it difficult to compare them, but showed differences in electrical activity between the studied groups (dysphonicsubjects, non-dysphonicsubjects, singers, and others. Conclusion: Electromyography has clinical applicability when technical precautions with respect to application and analysis are obeyed. However, it is necessary to adopt a universal system of assessment tasks and related measurement techniques to allow comparisons between studies.

    Hotelling T2 control chart is employed to monitor the stability of a multivariate process in Phase I and II. Traditional Hotelling T2 control chart using classical estimators in Phase I, however, suffers from masking and swamping effects and thus jeorpadizes its performance. To alleviate this problem, robust location and scale estimators are recommended instead. In this paper, a new Hotelling T2 control chart based on highly robust and efficient estimators of location and scatter estimators, known as reweighted minimum vector variance estimators, is proposed. Numerical results show that the new chart is not only capable of detecting outliers but it can also control the alarm rates better than the existing charts.

    Full Text Available Since Adam Smith , FW Taylor, H. Fayol and recently , whether we are referring to Peter Drucker, Harrington & Harrington, and other authors consecrated in the literature of management / economics, the organization issues in an organization have grown much in complexity. The manner in which the firm / company constitutes the organization chart induces subsequently, explicitly or not, multiple conditionings in the daily practice of the organization (both in the sense that it may favour certain efforts / strategies or on the contrary it may block such efforts. The size of the company, the market and the technology are the most popular factors that will influence an organization chart.. However, in the context of global crisis and chaotic business environment, new questions arise regarding the model of organization charts and associated management strategies. What are the predictable directions regarding the type of organization chart in the current business environment? How does social competition influence the shape of organization charts in different countries?

  16. A New Approach to Diagnosing Signals from Multivariate EWMA Control Chart

    MA Yi-zhong; ZHAO Feng-yu

    2003-01-01

    Since Lowry et al. [1992] proposed a multivariate version of the exponentially weighted moving average (EWMA) control chart, the multivariate EWMA control chart has become more and more popular in monitoring production processes, especially in chemical processes. A major advantage of multivariate EWMA statistics is that it is sensitive to small and moderate shifts in the mean vector. However, when a multivariate EWMA chart issues a signal, it is difficult to identify which variable or set of variables is out of control. In this paper, we introduce a new approach to diagnosing signals from a multivariate EWMA control chart. The implementation procedure is that when the multivariate EWMA control chart issues a signal, we adopt a univariate diagnostic procedure to identify the variables or/and the principal components that caused the signal.

  17. Obesity studies in the circumpolar Inuit: a scoping review

    2012-07-01

    Full Text Available Background. Among circumpolar populations, recent research has documented a significant increase in risk factors which are commonly associated with chronic disease, notably obesity. Objective. The present study undertakes a scoping review of research on obesity in the circumpolar Inuit to determine the extent obesity research has been undertaken, how well all subpopulations and geographic areas are represented, the methodologies used and whether they are sufficient in describing risk factors, and the prevalence and health outcomes associated with obesity. Design. Online databases were used to identify papers published 1992–2011, from which we selected 38 publications from Canada, the United States, and Greenland that used obesity as a primary or secondary outcome variable in 30 or more non-pregnant Inuit (“Eskimo” participants aged 2 years or older. Results. The majority of publications (92% reported cross-sectional studies while 8% examined retrospective cohorts. All but one of the studies collected measured data. Overall 84% of the publications examined obesity in adults. Those examining obesity in children focused on early childhood or adolescence. While most (66% reported 1 or more anthropometric indices, none incorporated direct measures of adiposity. Evaluated using a customized quality assessment instrument, 26% of studies achieved an “A” quality ranking, while 18 and 39% achieved quality rankings of “B” and “C”, respectively. Conclusions. While the quality of studies is generally high, research on obesity among Inuit would benefit from careful selection of methods and reference standards, direct measures of adiposity in adults and children, studies of preadolescent children, and prospective cohort studies linking early childhood exposures with obesity outcomes throughout childhood and adolescence.

  2. Control-Chart Dashboards: managing your numbers instead of your numbers managing you

    International Nuclear Information System (INIS)

    This paper, which documents Fluor Hanford's application of Statistical Process Control (SPC) and Dashboards to support planning and decision making, is a sequel to 'Leading with Leading Indicators' that was presented at WM '05. This year's paper provides more detail on management's use of SPC and control charts and discusses their integration into an executive summary using the popular color-coded dashboard methodology. Fluor Hanford has applied SPC in a non-traditional (that is non-manufacturing) manner. Dr. Shewhart's 75-year-old control-chart methodologies have been updated to modern data processing, but are still founded on his sound, tried and true principles. These methods are playing a key role in safety and quality at what has been called the world's largest environmental cleanup project. The U.S. Department of Energy's (DOE's) Hanford Site played a pivotal role in the nation's defense, beginning in the 1940's when it was established as part of the Manhattan Project. After more than 50 years of producing nuclear weapons, Hanford - which covers 586 square miles in southeastern Washington state - is now focused on three outcomes: 1. Restoring the Columbia River corridor for multiple uses 2. Transitioning the central plateau to support long-term waste management 3. Putting DOE assets to work for the future. The control-chart-based dashboard has been featured by several professional societies in their publications, most recently by the American Society of Safety Engineers. The case is provided for why one should consider switching from bar charts, moving averages, 'rainbow charts', and other non-statistical charting methods, and changing to control charts. Control charts have actually cost less to make than these other charts. Lessons learned from implementing the 'FluorBoard' control-chart-based dashboards will be included. These tools, management theories and methods, coupled with involved leadership and employee efforts, will directly lead to significant

  3. Radium in humans: A review of U.S. studies

    International Nuclear Information System (INIS)

    This document was originally conceived as a description of the radium studies that took place at Argonne National Laboratory. It soon became evident, however, that to document the widespread use of radium, a brief review of the application of radium in medicine and in the US dial painting industry is required. Further, because the Argonne studies were not the only such efforts, brief overviews of the other radium programs are included. Even so, much material has been omitted. The extensive references included will allow the interested reader to find additional information. The effects of internally deposited radium in humans have been studied in this country for more than 75 years. Some 2,400 subjects have had their body contents of radium measured, and a majority of them have been followed for most of their adult lives, to understand and quantify the effects of radium. Many more individuals acquired radium internally but were never measured. Some of this group have been located and followed until death; in these cases the cause of death is known without a body content measurement. As a consequence of the efforts made to locate, measure, and follow exposed individuals, a great deal of information about the effects of radium is available. Nevertheless, great gaps remain in the knowledge of radium toxicity. The Argonne study is the largest every undertaken of the effects on humans of an internally deposited radioelement, in which the insult has been quantitated by actual measurements of the retained radioisotope. The study has now been terminated, even though more than 1,000 subjects with measured radium burdens are still alive.

    Full Text Available Length of survival of cancer patients is an important indicator for knowing the outcome of treatment in any study. Epidemiological features and biological profile of breast cancer appear to be different in developing countries as compared to Western countries. Knowing the factors that influence survival rates among women with breast cancer may help define early detection actions, and improve treatment and care proposals in all the areas of health. Therefore, this study aims to identify, the publications defining the factors influencing survival for women with breast cancer in India. PUBMED database was searched from January 1990 to April 2016, using the key words Breast cancer, breast cancer outcome and Survival and their corresponding Mesh terms were used in combination with Boolean operators like OR, AND. Five year overall survival rate of breast cancer in India ranged from 40-62%. The results from 16 publications showed that survival of breast cancer varies widely depending on number of factors like age, stage at diagnosis, marital status, educational level, hormonal status, clinical extent of disease and treatment. The publications that make up this review present contributing factors that affect the survival rate of women with breast cancer in India. This information on survival studies can pinpoint the lacunae in treatment modalities and can guide us to do basic and translational research so the preventive strategies can be implemented.

    I. Basic Theory of Ethnic Law Studies As a mature discipline,research on the basic theory of ethnic law studies is no longer the focus of research. Nonetheless,this does not deny that it is a research of reflection and transcendence. In 2014,there were also important achievements with regard to this aspect. Concerning theory within the discipline of ethnic law studies,Wu Zongjin made a review on the development process of this disci ̄pline,and stated that the in-depth implementation of ethnic regional autonomy, the design of ethnic law institutions,the guarantee of ethnic rights legis ̄lation,and legal administration on ethnic work,etc. are still the responsibility of this discipline. Con ̄cerning the theory of the rule of law in ethnic are ̄as,it seems that a breakthrough was difficult. In 2014,Li Chao and Wang Huaju proposed a thor ̄ough evaluation of the rule of law in ethnic areas, but stated that this evaluation is facing problems due to the lack of local knowledge and lack of an efficient evaluation methodology and scientific su ̄pervision system. Hence,a concept for a scientific evaluation should be constructed, and local ethnic law resources should be found,and members of the various ethnic groups should participate.

    1994-09-01

    This document was originally conceived as a compilation of activities at Argonne National Laboratory that were directed toward the study of radium in humans. However, it soon became obvious that this was a very limited approach, because such a compilation would include no background on the widespread uses of radium in industry and in the medical profession, nor would it address the early history of the discovery of the hazards of radium. Such an approach would also ignore contributions to the study of radium effects made at other laboratories. This document now addresses these topics, in order to give an overall picture of what might be called the radium era, that period from the early part of this century, when radium was rapidly exploited as a tool and a medication, to the present time, when radium is not generally used and the study of its effects has been terminated. The appendix to this review lists all of the measured radium cases, a total of 2,403 individuals whose records were in the files at the end of 1990. For each case the route of exposure, the dates of exposure, the years of birth and death, the measured body content, the calculated intake and dose, and the cause of death have been listed. 165 refs.

    Full Text Available Diabetes mellitus is a public health problem which leads to serious complications over time. Experimentally, many herbs have been recommended for treating diabetes. In most cases, however, the recommendations are based on animal studies and limited pieces of evidence exist about their clinical usefulness. This review focused on the herbs, the hypoglycemic actions of which have been supported by three or more clinical studies. The search was done in Google Scholar, Medline and Science Direct databases using the key terms diabetes, plants, herbs, glucose and patients. According to the clinical studies, Aegle marmelos, Allium cepa, Gymnema sylvestre, Momordica charantia, Ocimum sanctum, Nigella sativa, Ocimum sanctum, Panax quinquefolius, Salacia reticulate, Silybum marianum and Trigonella foenum-graecum have shown hypoglycemic and, in some cases, hypolipidemic activities in diabetic patients. Among them, Gymnema sylvestre, Momordica charantia, Silybum marianum and Trigonella foenum-graecum have acquired enough reputation for managing diabetes. Thus, it seems that physicians can rely on these herbs and advise for the patients to improve management of diabetes.

    Autism Spectrum Disorder (ASD) affects 1 in 50 children between the ages of 6–17 years as per a 2012 CDC survey of parents. The etiology of ASD is not precisely known. ASD is an umbrella term, which includes low (IQ70) individuals. A better understanding of the disorder, and how it manifests in an individual subject can lead to more effective intervention plans to fulfill the individual’s treatment needs. Magnetic resonance imaging (MRI) is a non-invasive investigational tool that can help study the ways in which the brain develops and/or deviates from the typical developmental trajectory. MRI offers insights into the structure, function, and metabolism of the brain. In this article, we review published studies on brain connectivity changes in ASD using either resting state functional MRI or diffusion tensor imaging. The general findings of decreases in white matter integrity and long-range neural coherence are prevalent in ASD literature. However, there is somewhat less of a consensus in the detailed localization of these findings. There are even fewer studies linking these connectivity alterations with the behavioral phenotype of the disorder. Nevertheless, with the help of data sharing and large-scale analytic efforts, the field is advancing towards several convergent themes. These include reduced functional coherence of long-range intra-hemispheric cortico-cortical default mode circuitry, impaired inter-hemispheric regulation, and an associated, perhaps compensatory, increase in local and short-range cortico-subcortical coherence.

    2016-01-01

    Full Text Available Due to arising needs and demands, aquaculture is currently the fastest growing food production sector. In order to increase yield and yet to remain sustainable, the challenges would be to minimise impact on the environment and ecosystem services. Aquaculture activity contributes significantly to Malaysia and also the state of Sabah’s economy and food security. Hence, the future changes in the environment as a result of rapid population growth and development would pose as threats to this industry in terms of quality, quantity and sustainability. Unforeseen environmental changes such as environmental pollution from other sources, climate change and the changes in policies would jeopardize the sustainability of this industry. In order to anticipate such impacts to the aquaculture activities, this paper set to chart a sustainable course for its development. Four important research courses were proposed: establishment of a sustainable framework, assessment of impacts of climate change, viability and vulnerability assessment due to future environmental changes and food security. Such findings would eventually allow the stakeholders to plan and manage the resources and aquaculture activities in such a way that foster sustainable food security and resilient aquatic ecosystems.

    2005-09-01

    Full Text Available Based on the analysis of cartographic sources, the paper analyses the historical and geographical development of the Kornati islands, the largest group of Croatian islands. The old maps were used first of all as the means of geographic research that, being necessarily correlated to the simultaneous historical written sources and modern topographic and maritime maps, make the basis for creating a research platform for relevant scientific results to be achieved. On the basis of the old maps it is possible, among other things to anticipate that the Kornati islands used to have great geotraffic significance on the eastern Adriatic sailing route. According to the development of geographic concepts and cartographic methods, the geographic vision of the Kornati islands has been gradually clarified ever since the 16th century. The chart from the Carta di cabotaggio del Mare Adriatico edition published by the Military and Geographic Institute from Milan (1822-1824 presents the turning point with the first complete and mostly precise presentation of the Kornati islands group on the basis of hydrographic and topographic field measurements.

    Full Text Available The main purpose of this study was to construct reference standards for physical fitness (PF values, and to graphically highlight differences between Vouzela children and adolescents’ PF levels with those from other national and international references samples. Sample comprised 1920 children and adolescents aged 7 to 17 years. PF was assessed by five tests: handgrip, standing jump, shuttle run, 50-yard dash and 1-mile walk/run. Centile charts were constructed using the LMS method using the LMSchartmarker Pro software. Results suggest pervasive interindividual differences in motor performance. Boys showed higher values than girls for all tests, mainly during the pubertal period. Vouzela children and adolescents had similar performance to other samples in handgrip test, while the 50th percentile values from US sample were higher in standing jump, shuttle run, 50-yard dash tests. Vouzela performance in one mile walk/run was better than Azores and US samples.

    Full Text Available Participatory-action research encourages the involvement of all key stakeholders in the research process and is especially well suited to mental health research. Previous literature outlines the importance of engaging stakeholders in the development of research questions and methodologies, but little has been written about ensuring the involvement of all stakeholders (especially non-academic members in dissemination opportunities such as publication development. The Article Idea Chart was developed as a specific methodology for engaging all stakeholders in data analysis and publication development. It has been successfully utilised in a number of studies and is an effective tool for ensuring the dissemination process of participatory-action research results is both inclusive and transparent to all team members, regardless of stakeholder group.

    Ranjita Kumari Swain

    2012-08-01

    Full Text Available Today statecharts are a de facto standard in industry for modeling system behavior. Test data generation isone of the key issues in software testing. This paper proposes an reduction approach to test data generationfor the state-based software testing. In this paper, first state transition graph is derived from state chartdiagram. Then, all the required information are extracted from the state chart diagram. Then, test casesare generated. Lastly, a set of test cases are minimized by calculating the node coverage for each test case.It is also determined that which test cases are covered by other test cases. The advantage of our testgeneration technique is that it optimizes test coverage by minimizing time and cost. The present test datageneration scheme generates test cases which satisfy transition path coverage criteria, path coveragecriteria and action coverage criteria. A case study on Railway Ticket Vending Machine (RTVM has beenpresented to illustrate our approach.

    This study aims to explore practice, use, and risk of electroconvulsive therapy (ECT) in pregnancy. A systematic search was undertaken in the databases Medline, Embase, PsycINFO, SveMed and CINAHL (EBSCO). Only primary data-based studies reporting ECT undertaken during pregnancy were included. Two reviewers independently checked study titles and abstracts according to inclusion criteria and extracted detailed use, practice, and adverse effects data from full text retrieved articles. Studies and extracted data were sorted according to before and after year 1970, due to changes in ECT administration over time. A total of 67 case reports were included and studies from all continents represented. Altogether, 169 pregnant women were identified, treated during pregnancy with a mean number of 9.4 ECTs, at mean age of 29 years. Most women received ECT during the 2nd trimester and many were Para I. Main diagnostic indication in years 1970 to 2013 was Depression/Bipolar disorder (including psychotic depression). Missing data on fetus/child was 12 %. ECT parameter report was often sparse. Both bilateral and unilateral electrode placement was used and thiopental was the main anesthetic agent. Adverse events such as fetal heart rate reduction, uterine contractions, and premature labor (born between 29 and 37 gestation weeks) were reported for nearly one third (29 %). The overall child mortality rate was 7.1 %. Lethal outcomes for the fetus and/or baby had diverse associations. ECT during pregnancy is advised considered only as last resort treatment under very stringent diagnostic and clinical indications. Updated international guidelines are urgently needed. PMID:24271084

    Full Text Available BACKGROUND: Ratings in journal peer review can be affected by sources of bias. The bias variable investigated here was the information on whether authors had suggested a possible reviewer for their manuscript, and whether the editor had taken up that suggestion or had chosen a reviewer that had not been suggested by the authors. Studies have shown that author-suggested reviewers rate manuscripts more favorably than editor-suggested reviewers do. METHODOLOGY/PRINCIPAL FINDINGS: Reviewers' ratings on three evaluation criteria and the reviewers' final publication recommendations were available for 552 manuscripts (in total 1145 reviews that were submitted to Atmospheric Chemistry and Physics, an interactive open access journal using public peer review (authors' and reviewers' comments are publicly exchanged. Public peer review is supposed to bring a new openness to the reviewing process that will enhance its objectivity. In the statistical analysis the quality of a manuscript was controlled for to prevent favorable reviewers' ratings from being attributable to quality instead of to the bias variable. CONCLUSIONS/SIGNIFICANCE: Our results agree with those from other studies that editor-suggested reviewers rated manuscripts between 30% and 42% less favorably than author-suggested reviewers. Against this backdrop journal editors should consider either doing without the use of author-suggested reviewers or, if they are used, bringing in more than one editor-suggested reviewer for the review process (so that the review by author-suggested reviewers can be put in perspective.

    Priority setting research has focused on the macro (national) and micro (bedside) level, leaving the meso (institutional, hospital) level relatively neglected. This is surprising given the key role that hospitals play in the delivery of healthcare services and the large proportion of health systems resources that they absorb. To explore the factors that impact upon priority setting at the hospital level, we conducted a thematic review of empirical studies. A systematic search of PubMed, EBSCOHOST, Econlit databases and Google scholar was supplemented by a search of key websites and a manual search of relevant papers' reference lists. A total of 24 papers were identified from developed and developing countries. We applied a policy analysis framework to examine and synthesize the findings of the selected papers. Findings suggest that priority setting practice in hospitals was influenced by (1) contextual factors such as decision space, resource availability, financing arrangements, availability and use of information, organizational culture and leadership, (2) priority setting processes that depend on the type of priority setting activity, (3) content factors such as priority setting criteria and (4) actors, their interests and power relations. We observe that there is need for studies to examine these issues and the interplay between them in greater depth and propose a conceptual framework that might be useful in examining priority setting practices in hospitals.
