Full textAbstract:
Control charts are effective tools for signal detection in both manufacturing processes and service processes. Much of the data in service industries comes from processes having nonnormal or unknown distributions. The commonly used Shewhart variable control charts, which depend heavily on the normality assumption, are not appropriately used here. In this paper, we propose a new asymmetric EWMA variance chart (EWMA-AV chart) and an asymmetric EWMA mean chart (EWMA-AM chart) based on two simple statistics to monitor process variance and mean shifts simultaneously. Further, we explore the sampling properties of the new monitoring statistics and calculate the average run lengths when using both the EWMA-AV chart and the EWMA-AM chart. The performance of the EWMA-AV and EWMA-AM charts and that of some existing variance and mean charts are compared. A numerical example involving nonnormal service times from the service system of a bank branch in Taiwan is used to illustrate the applications of the EWMA-AV and EWMA-AM charts and to compare them with the existing variance (or standard deviation) and mean charts. The proposed EWMA-AV chart and EWMA-AM charts show superior detection performance compared to the existing variance and mean charts. The EWMA-AV chart and EWMA-AM chart are thus recommended.

Accurate determination of gestational age underpins good obstetric care. We assessed the performance of six existing ultrasound reference charts to determine gestational age in 1268 singleton IVF pregnancies, where “true” gestational age could be precisely calculated from date of fertilisation. All charts generated dates significantly different to IVF dates (P<0.0001 all comparisons). Thus we generated a new reference chart, The Monash Chart, based on a line of best fit describing crown-rump length across 6 + 1 to 9 + 0 weeks of gestation (true gestational age) in the IVF singleton cohort. The Monash Chart, but none of the existing charts, accurately determined gestational age among an independent IVF twin cohort (185 twin pairs). When applied to 3052 naturally-conceived singletons scans, The Monash Chart generated estimated due dates that were different to all existing charts (P≤0.004 all comparisons). We conclude that commonly used ultrasound reference charts have inaccuracies. We have generated a CRL reference chart based on true gestational age in an IVF cohort that can accurately determine gestational age at 6–9 weeks of gestation.

Control charts serve as an effective tool for controlling and monitoring process quality in industries of production and service. The Shewhart chart is the first control chart that was used to detect large mean shifts in a process. Since then, to increase the Shewhart chart’s sensitivity, synthetic type control charts, such as synthetic control chart, side sensitive group runs (SSGR) control chart, have been proposed. SSGR chart ismore efficient compared to the Shewhart chart and synthetic chart,primarily due to the side sensitive feature in SSGR chart. Meanwhile, exponentially weighted moving average (EWMA) chart isoften used to detect small process changes. In practice, the evaluation of a control chart’s performance is vital. Nevertheless, the cost of implementing a control chart is an important factor that influences the choice of a control chart. The cost of repairs, sampling, nonconforming products from a failure in detecting out-of-control status, and investigating false alarms, can be significantly high. Therefore, the aim of this paper is to compare the implementation cost of synthetic, SSGR and EWMA charts, so that quality practitioners can identify the most cost-effective chart to implement. Here, the cost function was adopted to compute the implementation cost of the control chart. According to the findings, quality practitioners are recommended to adopt the SSGR chart,since it is more economical compared to the synthetic chart. However, the cost to implement anEWMA chart is higher than the synthetic and SSGR charts. In light of this, this study allows for quality practitioners to have a better idea on the selection of the control chart to implement, with respect to its cost.

Full textAbstract:
Time-weighted graphs are used to detect small shifts in statistical process control. The aim of this study is to evaluate the inclination of the acetabular component with CUmulative SUM (CUSUM) chart, Moving Average (MA) chart, and Exponentially Weighted Moving Average (EWMA) chart. The data were obtained directly from thirty patients who had undergone total hip replacement surgery at Ondokuz Mayis University, Faculty of Medicine. The inclination of the acetabular component of these people, after total hip replacement, was evaluated. CUSUM chart, Moving Average chart, and Exponentially Weighted Moving Average were used to evaluate the quality control process of acetabular component inclination. MINITAB Statistical Software 15.0 was used to generate these control charts. The assessment done with time-weighted charts revealed that the acetabular inclination angles were settled within control limits and the process was under control. It was determined that the change within the control limits had a random pattern. As a result of this study it has been obtained that time-weighted quality control charts which are used mostly in the field of industry can also be used in the field of medicine. It has provided us with a faster visual decision.

Background Detecting developmental delay in children is an ongoing world commitment, especially for those below three years. To accurately assess the development of children; a culturally appropriate screening tool must be used. Egypt lacks such tool and multiple studies have shown that western tools are not suitable in other cultures. Objectives To develop and validate an easy, rapid, culturally appropriate and applicable screening chart for early detection of developmental delay among Egyptian children from birth up to 30 months and develop a Z-score chart for motor and mental development follow up based on our Egyptian screening chart. Methods A cross sectional randomized study was carried out on 1503 Egyptian children of both genders aged from birth up to 30 months assumed to have normal development according to the inclusion and exclusion criteria. They were selected from vaccination centers and well-baby clinics. Developmental milestones from Baroda development screening test (BDST) were applied on them after items were translated and adapted to Egyptian culture. Egyptian children developmental milestones scores were analyzed and carefully prepared in tables and charts. A 97% pass level of developmental achievements represents the threshold below which children are considered delayed. A Z-score chart for motor and mental development follow up was designed by calculating each age group achievement. The developed Egyptian developmental screening chart (EDSC) was validated against Ages and Stages Questionnaires (ASQ-3) as a reference standard in another different sample of 337 children in different age groups. Results The developed EDSC is represented in a chart format with two curves 50% and 97% pass level. Children considered delayed when the score below 97% pass level. Results revealed a statistically significant difference between EDSC and BDST at 50% and 97% pass levels. A Z-score chart for motor and mental development follow up was designed by calculating each age group achievement. EDSC sensitivity and specificity were calculated 84.38 (95% CI [67.21%–94.72%]) and 98.36 (95% CI [96.22%–99.47%]) respectively with an overall test accuracy 97.03 (95% CI [94.61%–98.57%]) (p ≤ .001). Agreement between EDSC and ASQ-3 was high (kappa score was 0.827) with negative and positive agreement 98.36 and 84.38, respectively. Conclusions Extensive revision of the BDST was needed in order to create and validate a more culturally appropriate Egyptian screening chart. This is the first study to create and validate an Egyptian-specific screening tool, to be rapid and easy to use in Egypt for early detection of developmental delay and enabling early intervention practices. A Z-score curve is reliable for follow up motor and mental development by calculating each age group achievement.

Full textAbstract:
A control chart is often used to monitor the industrial or services processes to improve the quality of the products. Mostly, the monitoring of location parameters, both in Phase I and Phase II, is done using a mean control chart with the assumption that the process is free from outliers or the estimators are correctly estimated from in-control samples. Generally, there are question marks about such kind of narratives. The performance of the mean chart is highly affected in the presence of outliers. Therefore, the median chart is an attractive alternative to the mean chart in this situation. The control charts are usually implemented in two phases: Phase I (retrospective) and Phase II (prospective/monitoring). The efficiency of any control chart in Phase II depends on the accuracy of control limits obtained from Phase I. The current study focuses on the Phase I analysis of location parameters using median control charts. We examined the performance of different auxiliary information-based median control charts and compared the results with the usual median chart. Standardized variance and relative efficacy are used as performance measures to evaluate the efficiency of median estimators. Moreover, the probability to signal measure is used to evaluate the performance of proposed control charts to detect any potential changes in the process. The results revealed that the proposed auxiliary information based median control charts perform better in Phase I analysis. In addition, a practical illustration of an industrial scenario demonstrated the significance of the proposed control charts, in which the monitoring of concrete compressive strength is emphasized.

Abstract. Statistical control charts are effective tools to reveal changes in a production process. The CUSUM (cumulative sum) and the EWMA (exponentially weighted moving average) control chart are used to detect small deviations in a process. Data from two sow herds, herd A and herd B, were collected from 1999 to 2004. Farm A had an average number of 530 breeding sows, Farm B had an average of 370 breeding sows. Both herds were diagnosed with Porcine Reproductive and Respiratory Syndrome (PRRS). The weekly means of the number of piglets weaned (NPW), the pre-weaning mortality (PWM) and return to service rate (RSR) were analysed with different settings of the CUSUM as well as the EWMA control chart to reveal a shift in the production process. For the pre-weaning mortality and the number of piglets weaned, the two charts detected a change in the process 4 weeks (Farm A) and 2 weeks before (Farm B) PRRS was diagnosed. The CUSUM and the EWMA chart revealed a shift in the return to service rate on Farm A 3.5 months before PRRS was detected. On Farm B, the signal occurred 6 weeks before the infection was detected. The CUSUM and the EWMA control charts were effective tools for detecting small deviations in sow herd data. Compared with EWMA, the use of the CUSUM chart is more straightforward and the settings are more easily handled. The CUSUM chart is therefore the preferred option for use in practice.

During the XIIth International Hydrographic Conference, held at Monaco in 1982, Anderson and this writer discussed Communication of the Nautical Chart. In that paper they traced the historical development of the nautical chart, noting how it had evolved and that features of the chart today had resulted more by evolution than by actual design. They noted, for instance, that although present-day charts are often produced by computer and make limited use of colour, they are not significantly different from charts produced some two hundred years ago. Computer methods have been used primarily to copy the work that was carried out so skilfully by the draughtsmen of earlier years. The authors after examining the historical development of the chart then touched lightly on some particular Canadian problems and went on to discuss the first principles of chart design. In particular they suggested that modern cartographic communications research might offer some help in developing the future design of the nautical chart. This paper is therefore a sequel to that work and is directed to presenting some ideas and furthering the discussion.

Full textAbstract:
In recent years, the suitable use of auxiliary information technique in control charts has shown an improved run length performance compared to control charts that do not have this feature. This article proposes a combined variable sampling interval (VSI) and double sampling (DS) chart using the auxiliary information (AI) technique (called VSIDS-AI chart, hereafter). The plotting-statistic of the VSIDS-AI chart requires information from both the study and auxiliary variables to efficiently detect process mean shifts. The charting statistics, optimal design and performance assessment of the VSIDS-AI chart are discussed. The steady-state average time to signal (ssATS) and steady-state expected average time to signal (ssEATS) are considered as the performance measures. The ssATS and ssEATS results of the VSIDS-AI chart are compared with those of the DS AI, variable sample size and sampling interval AI, exponentially weighted moving average AI (EWMA-AI) and run sum AI (RS-AI) charts. The results of comparison show that the VSIDS-AI chart outperforms the charts under comparison for all shift sizes, except the EWMA-AI and RS-AI charts for small shift sizes. An illustrative example is provided to demonstrate the implementation of the VSIDS-AI chart.

Quality control is an important role in industry for maintain quality stability. Statistical process control can quickly investigate the occurrence of unforeseen causes or process shifts using control charts. Mixed Exponentially Weighted Moving Average - Cumulative Sum (MEC) control chart is a tool used to monitor and evaluate whether the production process is in control or not. The MEC control chart method is a combination of the Exponentially Weighted Moving Average (EWMA) and Cumulative Sum (CUSUM) charts. Combining the two charts aims to increase the sensitivity of the control chart in detecting out of control. To compare the sensitivity level of the EWMA, CUSUM, and MEC methods, the Average Run Length (ARL) was used. From the comparison of ARL values, the MEC chart is the most sensitive control chart in detecting out of control compared to EWMA and CUSUM charts for small shifts.

The managing of complex business processes, which are changed due to globalization, calls for the development of powerful information systems that offer generic process modeling and
process execution capabilities.
Even though contemporary information systems are more and more utilized in enterprises, their actual impact in automatizing complex business process is still limited by the difficulties
encountered in design phase. Actually this design phase is time consuming, often subjective and incomplete.
In the scope of this study, a reverse approach is followed. Instead of starting with process design, the method of discovering interesting patterns from the navigation traces is taken as basis and a new data analysis methodology named &ldquo<br>From-to Chart Based Process Discovery&rdquo<br>is proposed.
In this hybrid methodology &ldquo<br>from-to chart&rdquo<br>, which is fundamentally dedicated to material handling issues on production floor, is used as the front-end to monitor the transitions among activities of a realistic event log and convert these raw relations into optimum activity sequence. Then a revised version of process mining, which is the back-end of this
methodology, upgrades optimum activity sequence into process model.

Full textAbstract:
Technical analysis as a sophisticated form of forecasting technique has a varying popularity in the academic and business world. In the past, users were sceptical about technical trading rules and their performance. This is substantiated by the acceptance of the Efficient Market Hypothesis and mixed empirical findings about technical analysis in widely cited studies.
The flag pattern is seen as one of the most significant spread chart patterns amongst stock market charting analysts. The present research validates a trading rule based on the further development of
flag pattern recognition. The research question concentrates on whether technical analysis applying the flag pattern can outperform international stock markets indices and prove the inefficiency of these markets. The markets observed are represented by the corresponding indices DAX (Germany), DJIA (United States) and IBEX (Spain).
The design of the trading rule presents several changes with respect to previous academic works: The wide sample used when considering intraday data, together with the confiuration of some of the variables and the consideration of risk, concludes that the trading rule provides greater positive risk-adjusted returns than the buy-and-hold strategy which is used as a benchmark. The reported positive results strengthen the robustness of the conclusions reached by other researchers.<br>El análisis técnico es una forma sofisticada de técnica de predicción cuya popularidad ha ido variando en el mundo académico y de los negocios.

El patrón bandera es visto como uno de los patrones gráficos más significativo y difundido entre los analistas técnicos de mercado. El presente estudio valida una regla

Full textAbstract:
Traditionally GT problems focus on the grouping aspects and fail to integrate material handling part in facility layout design. It is necessary to consider the flow between machines while forming machine cells and evaluate grouping based on flow and operational load factors. But after forming cells, machines have to be placed inside a layout to minimize the material handling distance. There are not many approaches which consider the actual volume flow between machines while grouping and the related handling distances while placing machine cells. Typical GT based cell formation problems stop after grouping cells and evaluating the quality of the grouped cells. This thesis develops a comprehensive cell formation model, which integrates the GT philosophy with a facility layout problem using From-between flow matrix as a tool. This approach forms machine cells using a Non-Linear Integer Programming (NLIP) optimization model, assigns parts to cells using a new heuristic algorithm, evaluates cell grouping using a novel grouping efficiency measure and places machine cells in a layout space using a GA approach. Known case studies from literature are selected and tested using the developed procedure. Results obtained show a reduction in the intercell flow, high grouping efficiency and minimal material handling costs after machine placement when compared with the existing models.<br>Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Industrial and Manufacturing Engineering

Full textAbstract:
Manufacturing facility layout is determined by minimizing the Material Handling (MH) cost associated with the manufacturing of products. A manufacturing facility operates in a dynamic environment where the production rates and product mix are continuously changing. In addition, the introduction of new products/machines and removal of existing products/machines render the existing layout completely unreliable to yield improved productivity. Hence, it is often necessary to analyze the current layout and redesign the layout in accordance with the constantly changes in demand. Existing methods for the analysis of redesign uses multiple, static, and tabular from-to charts. These charts assume and exhibit the timely demand as a discrete invariable quantity. A new tool, “Dynamic From Between Chart (DFBC)” that allows easier visualization of the changes in product rates and mix is introduced and developed in this research. DFBC models the production rate changes using a continuous function. The development process of the new tool, the formulation of the cost function and its application to the solution of Dynamic Facility Layout Problems (DFLP) for multiple time periods is presented with the use of a case study. The solution methodology uses a tradeoff analysis between increased MH cost and the rearrangement cost for the transition from existing layout to a new layout. To further authenticate and strengthen the developed methodology, real world case studies are considered and evaluated. Importance of any department flow over the other departments (crossover) occurs only if there is variation in the flow volumes between relative departments. In previous research, the redesign is carried out at the end of specific time period in a given time horizon. In most instances, the need for redesign or change in flow occurs somewhere during the period and identifying such crossover points will assist to yield better savings. In addition, the exact time at which the layout should be modified can be determined. For large size problems, the number of crossover points sited in DFBC will be large and evaluating each of these points to identify the point of change in layout will be tedious and time consuming. Thus, along with the methodology to identify the crossover points a concept of Upper bound and Lower bound (UB–LB) to discover the set of redesign points which may warrant a change in layout has been developed. Further analysis is necessary to detect the point(s) that initiate the change. Limiting the solution space facilitates the evaluation of large size problems by reducing and simplifying the computation. Multiple case studies are considered and evaluated to indicate the applicability of the concept. It is also evident in current manufacturing paradigms that the introduction of new products/machines and removal of existing products/machines in-between the time horizon induces huge flow variations between departments. Previous research on DFLP does not deal with models which adopt such scenarios. In this research the application of DFBC to analyze the impact of introduction of new products/machines and removal of existing products/machines in between the time horizon is considered. The ability of the DFBC to address such scenarios is evaluated using a case study. Finally, the possible extensions of this research are listed along with the conclusions on the proposed approach.<br>Thesis (Ph.D.)--Wichita State University, College of Engineering, Dept. of Industrial and Manufacturing Engineering<br>"December 2007."

Questo elaborato di tesi tratta il progetto di re-layout che ha interessato la Business Unit Medical Equipment della società cooperativa Cefla, leader europeo nel settore delle strumentazioni per odontoiatri. L’azienda ha infatti deliberato la costruzione nel 2023 di un nuovo edificio dedicato alla produzione con pianta da circa 11000 m^2, da affiancare allo stabilimento attuale da 40000 m^2.
Il progetto è stato realizzato seguendo la procedura consigliata dal modello del Systematic Layout Planning e si articola nella mappatura dei flussi tra i reparti dell’impianto, nel disegno delle soluzioni alternative e nella scelta della soluzione ritenuta migliore.
L’impianto produttivo è composto da 47 reparti, le cui aree a disposizione sono state adattate, nelle ipotesi del futuro layout, in modo da essere in linea con i piani di produzione dell’azienda negli anni a seguire.
Le diverse soluzioni di layout realizzate prevedono due utilizzi differenti del nuovo edificio. La scelta tra le alternative è avvenuta basandosi principalmente sul criterio della minore distanza annuale percorsa per le movimentazioni tra i reparti, pur tenendo conto anche dei vantaggi e svantaggi di ogni soluzione.

Il seguente elaborato evidenzia il processo utilizzato per arrivare allo sviluppo di uno strumento che favorisca il processo decisionale all’interno dell’azienda One Express.
Riporta le attività preliminari realizzate per arrivare ad una comprensione chiara e univoca del processo, in particolare: mappatura BPMN, realizzazione del layout aziendale e analisi “tempi e metodi”.
Dall’analisi sono emerse le principali criticità che sono state classificate sia in termini strategici come la mancanza di un sistema a supporto per la scelta della buca di scarico ottimale, sia in termini operativi come la saturazione dei polmoni e il disaccoppiamento dell’attività di carico e scarico.
Tutto questo ha portato allo sviluppo di 2 strumenti: un simulatore e costificatore per l’analisi del tempo ciclo del processo e determinazione del numero di operatori e dei modelli di dock assignment per la definizione della buca di scarico ottimale.
Dai modelli realizzati si è andata ad evidenziare la diversa configurazione che essi generavano rispetto alla situazione AS-IS.
Per il modello [7] il più completo tra quelli sviluppati, che consente la valutazione della buca di scarico da assegnare considerando la possibilità di scaricare in due hub, la scelta tra navettaggio e doppio scarico e della buca di scarico della navetta, è stata sviluppata un’analisi su un orizzonte temporale di 4 ore per verificare con maggior precisione la bontà del modello.
I risultati ottenuti hanno dimostrato come il carico di lavoro richiesto per le attività di smistamento può essere ridotto significativamente.
I modelli per come sono stati pensati e sviluppati potrebbero avere sia una applicazione strategica atta a programmare anticipatamente le buche di scarico dei mezzi sia una operativa, in caso di disallineamento tra la situazione reale e quella attesa.

Full textAbstract:
Det ligger en stor utmaning i att presentera komplex information visuellt, så att betraktaren kan förstå datan och ta till sig budskapet. Att arbeta kreativt med färg och form för att presentera information kan underlätta förståelsen för datan samt skapa ett intresse. Ett bra verktyg för informationsvisualisering är diagram, med vilket data kan presenteras på ett pedagogiskt och överskådligt sätt. Syftet med detta designarbete har således varit att utforska hur diagram kan utformas så att de både är intresseväckande och lättförståeliga. Diagram som används av företaget Health Profile Institute är ett tydligt exempel på designproblemet, dessa har därför agerat som exempel inom denna studie. Utforskande design har använts som metod inom denna studie. Författarna har därför tagit fram ett stort antal designförslag i form av konceptskisser på olika diagramtyper. Författarna har dragit slutsatserna att diagram som både är intresseväckande och enkla att förstå kan skapas genom en väl utförd formgivning. Genom att arbeta med kontraster i färg och form, samt användning av ikoner och olika nivåer i formgivningen, orienterar diagrammet betraktaren. Dessutom kan intresse skapas eftersom det framkallar associationer hos betraktaren, intresseväckande och lättförståelighet hänger således ihop vid utformning av diagram.

Full textAbstract:
The work described in this thesis falls into two sections. (1) Data derived from Raman spectroscopy have been compared with data obtained from other techniques (X-ray diffraction and optical spectroscopy) in order to establish the nature of the fundamental information available from the Raman spectra available from coals and coal chars. It has thus been established that the Raman spectra of the materials examined are dependent upon the sizes of the aromatic carbon layers of which they are composed, and this in turn is determined by the maximum heat treatment temperature to which the materials have been subjected. This relationship has been investigated in detail, in order that it may be used to measure the maximum heat treatment temperature of a coal char of unknown thermal history. It has been established that preparation conditions other than temperature, such as pressure, atmosphere, heating rate, soak time and tar addition have a negligible effect on this relationship, and thus its general applicability to the study of chars of unknown thermal history has been established. (2) Both Raman spectroscopy and optical microscopy have been applied to coal chars produced in, and subsequently removed from, the British Gas Slagging Gasifier. Optical microscopy was used to assess the homogeneity or heterogeneity of the chars; Raman spectroscopy was then applied to the homogeneous chars, and thermal profiles within the gasifier were established for several gasifier runs.

Abstract While Open Data (OD) publishers are spur in providing data as Linked Open Data (LOD) to boost innovation and knowledge creation, the complexity of RDF querying languages, such as SPARQL, threatens their exploitation. We aim to help lay users (by focusing on experts in table manipulation, such as OD experts) in querying and exploiting LOD by taking advantage of our target users’ expertise in table manipulation and chart creation. We propose QueDI (Query Data of Interest), a question-answering and visualization tool that implements a scaffold transitional approach to 1) query LOD without being aware of SPARQL and representing results by data tables; 2) once reached our target user comfort zone, users can manipulate and 3) visually represent data by exportable and dynamic visualizations. The main novelty of our approach is the split of the querying phase in SPARQL query building and data table manipulation. In this article, we present the QueDI operating mechanism, its interface supported by a guided use-case over DBpedia, and the evaluation of its accuracy and usability level.

Full textAbstract:
Transformative pedagogy is a contemporary educational ideal intended to actively promote the transformation of the life and inner perception of the learner and his/her community. It emerged at the dawn of the 21st century from a line of counter-hegemonic thought that has been called emancipatory, liberal, radical or critical in the effort to chart a new direction for post-industrial education. This paper addresses the struggle of architectural education to maintain its aim as an emancipatory practice within an ever-evolving disciplinary culture.

Full textAbstract:
Auditory graphs are a very useful way to deliver numerical information to visually impaired users. Several tools have been proposed for chart data sonification, including audible spreadsheets, custom interfaces, interactive tools and automatic models. In the case of the latter, most of these models are aimed towards the extraction of contextual information and not many solutions have been proposed for the generation of an auditory graph directly from the pixels of an image by the automatic extraction of the underlying data. These kind of tools can dramatically augment the availability and usability of auditory graphs for the visually impaired community. We propose a deep learning-based approach for the generation of an automatic sonification of an image containing a bar or a line chart using only pixel information. In particular, we took a denoising approach to this problem, based on a fully symmetric convolutional neural network architecture. Our results show that this approach works as a basis for the automatic sonification of charts directly from the information contained in the pixels of an image.

Full textAbstract:
Purpose/Background: Adverse Childhood Experiences (ACEs) have an impact on health throughout the lifespan (Filletti et al., 1999; Hughes et al., 2017). These experiences range from physical and mental abuse, substance abuse in the home, parental separation or loss, financial instability, acute illness or injury, witnessing violence in the home or community, and incarceration of family members (Hughes et al., 2017). Understanding and screening for ACEs in children with urinary incontinence can help practitioners identify psychological stress as a potentially modifiable risk factor. Methods: A 5-month chart review was performed identifying English speaking patients ages 6-11 years presenting to the outpatient urology office for an initial visit with a primary diagnosis of urinary incontinence. Charts were reviewed for documentation of individual or family risk factors for ACEs exposure, community risk factors for ACEs exposures, and records where no related documentation was included. Results: For the thirty-nine patients identified, no community risk factors were noted in the charts. Seventy-nine percent of patients had one or more individual or family risk factors documented. Implications for Nursing Practice This chart review indicates that a significant percentage of pediatric, school-aged patients presenting with urinary incontinence have exposure to ACEs. A formal assessment for ACEs at the time of initial presentation would be helpful to identify those at highest risk.

Full textAbstract:
With specific regard to interstates in the rural area, Indiana Department of Transportation (INDOT) has expressed a need for research that sheds light on this Maintenance of Traffic (MOT) issue so the agency [INDOT and the contractor] can make informed decisions regarding the crossover sections versus the closure in one direction with detour roads. A number of studies have investigated the advantages and disadvantages of various MOT strategies; however, there is no specific study that can help INDOT traffic engineers and design engineers make decisions by comparing direct and indirect benefits of crossovers and detours (full lane closures). This research examined the advantages and disadvantages of entirely closing one direction of traffic over traditional work zone techniques (such as partial lane closure through median crossover) from the perspectives of the agency, road users, and the community. In the case of full closure, the study (a) examined the alternative MOT strategies and best practices through an extensive literature review and survey of agencies (b) investigated risk, benefit, and costs associated with selected detour routes (c) validated the identified critical factors through case studies in Indiana and at other states, and (d) implemented best practices in an expected project to evaluate the safety, mobility, and cost benefits of closing one direction. Through the literature review and four case studies, eleven KPIs for MOT strategy developments were identified. This study prioritized these KPIs through the survey questionnaire. The top five KPIs are (1) safety, (2) mobility, (3) budget constraint, (4) project duration, (5) complexity of project sites. Based on these KPIs and other findings presented in Section 4.3.3, this study has proposed a comparison tool for predetermined MOT strategies in the form of a flow-chart. This tool is followed by the scores or weights associated with each KPI. These scores are normalized—i.e., the most important KPI which is safety, has the maximum weightage 1 and rest of the KPIs are weighed relatively. INDOT has a set of editable documents which are references for making MOT decisions. This proposed flow-chart tool will “walk” the INDOT team through the use of these spreadsheets corresponding to the identified KPIs through this study. It will be at the discretion of the INDOT team as to which KPIs are relevant to the situation at hand. Therefore, the flow-chart tool is flexible to incorporate the dynamic nature of MOT strategy selection.

Full textAbstract:
Background Diabetes mellitus (DM) and depression are important comorbid conditions that can lead to more serious health outcomes. The American Diabetes Association (ADA) supports routine screening for depression as part of standard diabetes management. The PHQ2 and PHQ9 questionnaires are good diagnostic screening tools used for major depressive disorders in Type 2 diabetes mellitus (DM2). This quality improvement study aims to compare the rate of depression screening, treatment, and referral to behavioral health in adult patients with DM2 pre and post-integration of depression screening tools into the electronic health record (EHR). Methods We conducted a retrospective chart review on patients aged 18 years and above with a diagnosis of DM2 and no initial diagnosis of depression or other mental illnesses. Chart reviews included those from 2018 or prior for before integration data and 2020 to present for after integration. Sixty subjects were randomly selected from a pool of 33,695 patients in the clinic with DM2 from the year 2013-2021. Thirty of the patients were prior to the integration of depression screening tools PHQ2 and PHQ9 into the EHR, while the other half were post-integration. The study population ranged from 18-83 years old. Results All subjects (100%) were screened using PHQ2 before integration and after integration. Twenty percent of patients screened had a positive PHQ2 among subjects before integration, while 10% had a positive PHQ2 after integration. Twenty percent of patients were screened with a PHQ9 pre-integration which accounted for 100% of those subjects with a positive PHQ2. However, of the 10% of patients with a positive PHQ2 post-integration, only 6.7 % of subjects were screened, which means not all patients with a positive PHQ2 were adequately screened post-integration. Interestingly, 10% of patients were treated with antidepressants before integration, while none were treated with medications in the post-integration group. There were no referrals made to the behavior team in either group. Conclusion There is no difference between the prevalence of depression screening before or after integration of depression screening tools in the EHR. The study noted that there is a decrease in the treatment using antidepressants after integration. However, other undetermined conditions could have influenced this. Furthermore, not all patients with positive PHQ2 in the after-integration group were screened with PHQ9. The authors are unsure if the integration of the depression screens influenced this change. In both groups, there is no difference between referrals to the behavior team. Implications to Nursing Practice This quality improvement study shows that providers are good at screening their DM2 patients for depression whether the screening tools were incorporated in the EHR or not. However, future studies regarding providers, support staff, and patient convenience relating to accessibility and availability of the tool should be made. Additional issues to consider are documentation reliability, hours of work to scan documents in the chart, risk of documentation getting lost, and the use of paper that requires shredding to comply with privacy.

Brown, Yolanda, Twonia Goyer, and Maragaret Harvey. Heart Failure 30-Day Readmission Frequency, Rates, and HF Classification. University of Tennessee Health Science Center, 2020. http://dx.doi.org/10.21007/con.dnp.2020.0002.
Full textAbstract:
30 Day Hospital Readmission Rates, Frequencies, and Heart Failure Classification for Patients with Heart Failure Background Congestive heart failure (CHF) is the leading cause of mortality, morbidity, and disability worldwide among patients. Both the incidence and the prevalence of heart failure are age dependent and are relatively common in individuals 40 years of age and older. CHF is one of the leading causes of inpatient hospitalization readmission in the United States, with readmission rates remaining above the 20% goal within 30 days. The Center for Medicare and Medicaid Services imposes a 3% reimbursement penalty for excessive readmissions including those who are readmitted within 30 days from prior hospitalization for heart failure. Hospitals risk losing millions of dollars due to poor performance. A reduction in CHF readmission rates not only improves healthcare system expenditures, but also patients’ mortality, morbidity, and quality of life. Purpose The purpose of this DNP project is to determine the 30-day hospital readmission rates, frequencies, and heart failure classification for patients with heart failure. Specific aims include comparing computed annual re-admission rates with national average, determine the number of multiple 30-day re-admissions, provide descriptive data for demographic variables, and correlate age and heart failure classification with the number of multiple re-admissions. Methods A retrospective chart review was used to collect hospital admission and study data. The setting occurred in an urban hospital in Memphis, TN. The study was reviewed by the UTHSC Internal Review Board and deemed exempt. The electronic medical records were queried from July 1, 2019 through December 31, 2019 for heart failure ICD-10 codes beginning with the prefix 150 and a report was generated. Data was cleaned such that each patient admitted had only one heart failure ICD-10 code. The total number of heart failure admissions was computed and compared to national average. Using age ranges 40-80, the number of patients re-admitted withing 30 days was computed and descriptive and inferential statistics were computed using Microsoft Excel and R. Results A total of 3524 patients were admitted for heart failure within the six-month time frame. Of those, 297 were re-admitted within 30 days for heart failure exacerbation (8.39%). An annual estimate was computed (16.86%), well below the national average (21%). Of those re-admitted within 30 days, 50 were re-admitted on multiple occasions sequentially, ranging from 2-8 re-admissions. The median age was 60 and 60% male. Due to the skewed distribution (most re-admitted twice), nonparametric statistics were used for correlation. While graphic display of charts suggested a trend for most multiple re-admissions due to diastolic dysfunction and least number due to systolic heart failure, there was no statistically significant correlation between age and number or multiple re-admissions (Spearman rank, p = 0.6208) or number of multiple re-admissions and heart failure classification (Kruskal Wallis, p =0.2553).

Full textAbstract:
INTRODUCTION: Palliative care continues to gain recognition among primary care providers, as patients suffering from chronic conditions may benefit from use of this growing service. OBJECTIVES: This single-institution quality improvement study investigates the clinical characteristics and socioeconomic status (SES) of palliative care patients and identifies predictors of palliative care utilization. METHODS: Retrospective chart review was used to compare clinical and SES parameters for three groups of patients: (1) palliative care patients who attended at least one visit since the inception of the University Clinical Health Palliative Care Clinic in Memphis, TN in October 2018 (n = 61), (2) palliative care patients who did not attend any appointments (n = 19), and (3) a randomized group of age-matched primary care patients seen by one provider from May 2018 to May 2019 (n = 36). A Poisson regression model with backward conditional variable selection was used to determine predictors of palliative care utilization. RESULTS: Patients across the three care groups did not differ in demographic parameters. Compared to palliative care-referred non-users and primary care patients, palliative care patients tended to have lower health risk (p < 0.001). Palliative care patients did not differ from primary care patients in socioeconomic status but did differ in comorbidity distribution, having a higher prevalence of cancer (𝜒2 = 14.648, df = 7, p = 0.041). Chance of 10-year survival did not differ across risk categories for palliative care patients but was significantly lower for very high-risk compared to moderate-risk primary care patients (30% vs. 78%, p = 0.019). Significant predictors of palliative care use and their corresponding incidence rate ratios (IRR) were hospital referral (IRR = 1.471; p = 0.039), higher number of prescribed medications (IRR = 1.045; p = 0.003), lower Charlson Comorbidity Index (IRR = 0.907; p = 0.003), and lower systolic blood pressure (IRR = 0.989; p = 0.004). CONCLUSIONS: Patients who are expected to benefit from and of being high utilizers of palliative care may experience greater clinical benefit from earlier referral to this service.

Efficacy of Integrating CBT for Mental Health Care into Substance Abuse Treatment in Patients with Comorbid Disorders of Substance Abuse and Mental Illness. University of Tennessee Health Science Center, 2021. http://dx.doi.org/10.21007/con.dnp.2021.0004.
Full textAbstract:
Abstract: Multiple studies have found that psychiatric disorders, like mood disorders and substance use disorders, are highly comorbid among adults with either disorder. Integrated treatment refers to the treatment of two or more conditions and the use of multiple therapies such as the combination of psychotherapy and pharmacotherapy. Integrated therapy for comorbidity per numerous studies has consistently been superior to the treatment of individual disorders separately. The purpose of this QI project was to identify the effectiveness of Cognitive Behavioral Therapy (CBT) instead of current treatment as usual for treating Substance Use Disorder (SUD) or mental health diagnosis independently. It is a retrospective chart review. The review examines CBT's efficacy for engaging individuals with co-occurring mood and substance u se disorders in treatment by enhancing adherence and preventing disengagement and relapse. Methods: Forty adults aged 26-55 with a DSM-IV diagnosis of a mood disorder of Major Depressive Disorder and/or anxiety and concurrent substance use disorder (at least weekly use in the past month). Participants received 12 sessions of individual integrated CBT treatment delivered with case management over a 12-week period. Results: The intervention was associated with significant improvements in mood disorder, substance use, and coping skills at 4, 8, and 12 weeks post-treatment. Conclusions: These results provide some evidence for the effectiveness of the integrated CBT intervention in individuals with co-occurring disorders. Of note, all psychotherapies are efficacious; however, it would be more advantageous to develop a standardized CBT that identifies variables that facilitate treatment outcomes specifically to comorbid disorders of substance use and mood disorders. It is concluded that there is potentially more to be gained from further studies using randomized controlled designs to determine its efficacy.

The main recommendations of the panel report can be summarised under five key headings. Underpinning all five areas is the recognition that human narratives remain crucial for ensuring the widest access to our shared past. There is no wish to see political and economic narratives abandoned but the need is recognised for there to be an expansion to more social narratives to fully explore the potential of the diverse evidence base. The questions that can be asked are here framed in a national context but they need to be supported and improved a) by the development of regional research frameworks, and b) by an enhanced study of Scotland’s international context through time. 1. From North Britain to the Idea of Scotland: Understanding why, where and how ‘Scotland’ emerges provides a focal point of research. Investigating state formation requires work from Medieval Scotland: a future for its past ii a variety of sources, exploring the relationships between centres of consumption - royal, ecclesiastical and urban - and their hinterlands. Working from site-specific work to regional analysis, researchers can explore how what would become ‘Scotland’ came to be, and whence sprang its inspiration. 2. Lifestyles and Living Spaces: Holistic approaches to exploring medieval settlement should be promoted, combining landscape studies with artefactual, environmental, and documentary work. Understanding the role of individual sites within wider local, regional and national settlement systems should be promoted, and chronological frameworks developed to chart the changing nature of Medieval settlement. 3. Mentalities: The holistic understanding of medieval belief (particularly, but not exclusively, in its early medieval or early historic phase) needs to broaden its contextual understanding with reference to prehistoric or inherited belief systems and frames of reference. Collaborative approaches should draw on international parallels and analogues in pursuit of defining and contrasting local or regional belief systems through integrated studies of portable material culture, monumentality and landscape. 4. Empowerment: Revisiting museum collections and renewing the study of newly retrieved artefacts is vital to a broader understanding of the dynamics of writing within society. Text needs to be seen less as a metaphor and more as a technological and social innovation in material culture which will help the understanding of it as an experienced, imaginatively rich reality of life. In archaeological terms, the study of the relatively neglected cultural areas of sensory perception, memory, learning and play needs to be promoted to enrich the understanding of past social behaviours. 5. Parameters: Multi-disciplinary, collaborative, and cross-sector approaches should be encouraged in order to release the research potential of all sectors of archaeology. Creative solutions should be sought to the challenges of transmitting the importance of archaeological work and conserving the resource for current and future research.

Full textAbstract:
Six geodetic datums have been used by the US Army Corps of Engineers (USACE), Mississippi River Commission (MRC), for river surveys in the Lower Mississippi Valley (LMV). These legacy elevation datums are the Cairo datum, the Memphis datum, the Mean Gulf Level (MGL), the Mean Sea Level (MSL), the National Geodetic Vertical Datum (NGVD) 1929, and the North American Vertical Datum 1988 (NAVD88). The official geodetic datum currently prescribed by the USACE is NAVD88 (USACE 2010). In addition to these different geodetic datums, hydraulic datums are in use by the USACE for rivers, lakes, and reservoir systems. Hydrographic surveys from the Mississippi River are typically based on a low water pool or discharge reference, such as a low water reference plane (LWRP), an average low water plane (ALWP), or a low water (LW) plane. The following technical note is intended to provide background information about legacy datums used in the LMV to permit comparison of historic maps, charts, and surveys pertaining to the Mississippi River in the LMV. The purpose of this report is to provide background information and history of different published horizontal and vertical datums used for presentation of hydrographic survey data from the Mississippi River. The goal is to facilitate understanding of differences with comparison to other historic surveys for change-detection studies along the river. Conversion values are identified herein for the earlier surveys where appropriate, and methods are presented here to evaluate the differences between earlier and later charts and maps. This report is solely intended to address the LMV area and historic surveys made there. This note is not applicable to areas outside of the LMV. Throughout this technical note, historic hydrographic surveys and data from the Memphis, TN, to Rosedale, MS, reach will be used as examples of features of interest for discussion purposes. Selected historic hydrographic survey sheets at Helena, AR, are included as Plates 1 to 3 (Appendix C) of this document and will be used as examples for discussion purposes.

Woods, Rachel, Alison Zhong, and Madelyn Vincent. Factors Associated with Influenza & Tdap Vaccine Uptake in Pregnant Patients at the UT Family Medicine Clinic in Memphis. University of Tennessee Health Science Center, 2021. http://dx.doi.org/10.21007/com.lsp.2020.0003.
Full textAbstract:
INTRODUCTION: Given the increased risk for infections among pregnant patients and newborns, vaccination against influenza (>50,000,000 annual US cases affecting all ages) and pertussis (>15,000 annual US cases disproportionately affecting newborns) are recommended among pregnant patients in order to protect them and their babies via passive immunity to cover a newborn’s window of vaccine ineligibility. Though flu and Tdap vaccination rates among pregnant patients have been trending upwards nationally, there is still room for improvement to achieve optimal rates. OBJECTIVES: The primary objectives were to study factors that affect the vaccination rates at the University of Tennessee Family Medicine Clinic at Memphis (UTFMC-M), compare those rates with national pregnancy flu/Tdap vaccination rates, and to generate recommendations based off observed factors associated with vaccine uptake to improve flu/Tdap vaccination rates in UTFMC-M pregnant patients. METHODS: This was a retrospective chart review of UTFMC-M patients who were pregnant from September 1, 2019-April 24, 2020 (included 2019-2020 flu season) (n=465). Variables studied included demographic data (race, age, insurance), immunization history (vaccine status, history of physician encouragement), and prenatal history (parity, number of prenatal visits, trimester at first visit, high risk clinic (HRC) admittance status). Vaccination status was based on ACIP recommendations (Flu shot eligible = any gestational age; Tdap eligible = ≥27 weeks). Positive HRC admittance was noted for patients with ≥2 visits to the UTFMC-M HRC, a clinic that specializes in high risk pregnant patient care. RESULTS: The patient sample was predominantly black (84.3%) and insured by Medicaid programs (88%). Among eligible UTFMC-M pregnant patients, 50.1% were flu-vaccinated (n=465); 73.8% were Tdap-vaccinated (n=317); and 52.1% were Flu+Tdap-vaccinated (n=317). No significant associations were found between vaccine uptake and HRC status, parity, and age. However, statistically significant relationships were found between vaccine uptake and physician encouragement (positive relationship with flu shot: X2(1, N = 465) =131, p < 0.001, Tdap: X2 (6, N = 465) =476, p < 0.001), number of prenatal visits (flu shot group median 8 visits, Tdap group median 9 visits vs. unvaccinated group median 4 visits; p < 0.001), and early trimester age at first prenatal visit (X2(6, N = 465) =47.635 , p CONCLUSION: 2019-2020 UTFMC-M vaccination rates were on par with 2018-2019 US flu vaccine rates and higher than 2018-2019 US Tdap and Flu+Tdap rates. There were statistically significant relationships between vaccine uptake at UTFMC-M and physician encouragement, number of prenatal visits, and early trimester age at first prenatal visit but no significant relationships with UTFMC-M HRC admittance, parity, or age. Recommendations following from our observations to address further vaccine rate improvement include: continue vaccine encouragement, continue booking multiple visits (8 for flu, 9 for Tdap), prioritize Tdap vaccine higher for late trimester intake patients, and focus on flu vaccine encouragement and education.
