    The aim of this project was to develop and deliver an evidence-based educational package with a physical and mental health focus to clinicians and other health care workers in mental health settings. For individuals who experience mental disorders, pharmacotherapy is often considered as a first line of treatment. However, owing to adverse drug reactions and pre-existing physical conditions, outcomes for clients/service users may be compromised. Mortality and morbidity rates of people diagnosed with a serious mental illness caused by physical health conditions do not compare favourably with the general population. This paper reports on a physical skills project that was developed in collaboration between the University of Huddersfield and South West Yorkshire Partnership Foundation Trust. Pre-post study design: five workshops were conducted in the fields of intramuscular injections, diabetes, health improvement, oral health and wound care. A total of 180 pairs of questionnaires to assess practitioner and student skills and knowledge were administered to participants before and after workshops. All workshops resulted in a statistically significant improvement in subject skills and knowledge scores (P Mental health nurses are the largest group of registered practitioners working in the mental health setting and thus need to be harnessed to make a positive contribution to the improvement of the physical health status of service users with a serious mental illness. © 2014 John Wiley & Sons Ltd.

    Early identification and management of child and adolescent mental health (CAMH) disorders helps to avert mental illness in adulthood but a CAMH treatment gap exists in Uganda. CAMH integration into primary health care (PHC) through in-service training of non-specialist health workers (NSHW) using the World Health Organisation (WHO) Mental Health Gap Action Programme (mhGAP) Intervention Guide (IG) is a strategy to address this gap. However, results of such training are not supported by information on training development or delivery; and are undifferentiated by NSHW cadre. We aim to describe an in-service CAMH training for NSHW in Uganda and assess cadre-differentiated learning outcomes. Thirty-six clinical officers, nurses and midwives from 18 randomly selected PHC clinics in eastern Uganda were trained for 5 days on CAMH screening and referral using a curriculum based on the mhGAP-IG version 1.0 and PowerPoint slides from the International Association of Child and Adolescent Psychiatry and Allied Professions (IACAPAP). The residential training was evaluated through pre- and post- training tests of CAMH knowledge and attitudes using the participants' post-test scores; and the difference between pre-test and post-test scores. Two-tailed t-tests assessed differences in mean pre-test and post-test scores between the cadres; hierarchical linear regression tested the association between cadre and post test scores; and logistic regression evaluated the relationship between cadre and knowledge gain at three pre-determined cut off points. Thirty-three participants completed both pre-and post-tests. Improved mean scores from pre- to post-test were observed for both clinical officers (20% change) and nurse/midwives (18% change). Clinical officers had significantly higher mean test scores than nurses and midwives (p training. Thus, an option for integrating CAMH into PHC in Uganda using the mhGAP-IG and IACAPAP PowerPoint slides is to proceed without cadre differentiation.

    A survey was conducted to assess the impact of a TED-like educational session on participants' willingness to accept dental implant therapy. Volunteers interested in having information about dental implant therapies were recruited and asked to complete a two-part survey before and after an educational session. The initial survey elicited demographic information, self-perceived knowledge on dental implants and willingness to this kind of treatment. A "TED-style" presentation that provided information about dental implant treatments was conducted before asking the participants to complete a second set of questions assessing the impact of the session. The survey was completed by 104 individuals, 78.8% were women and the mean age was 66.5±10.8. Before the educational session, 76.0% of the participants refused dental implants mainly due to lack of knowledge. After the educational session, the rejection of dental implants decreased by almost four folds to 20.2%. This study proved that an educational intervention can significantly increase willingness to accept treatment with dental implants in a segment of the population who is interested in having information about dental implant therapy. Furthermore, educational interventions, such as TED-like talks, might be useful to increase popular awareness on dental implant therapy.

    Full Text Available Introduction: This paper aims to evaluate the results of the assessment and comparison of the impact of information literacy in e-learning and in-class courses at the Faculty of Medicine, Masaryk University, Czech Republic. The objective herein is to show that e-learning can be as effective a method of teaching IL activities as in-class lessons. Methods: In the autumn of 2012 and the spring of 2013, a total of 159 medical students enrolled in the e-learning course and completed the required pre-tests and post-tests comprising 30 multiple-choice questions on information literacy topics; another 92 PhD students from in-class courses took the 22-question test. The pre-test and post-test scores along with the number of students who correctly answered the questions were counted and the overall percentage was calculated. The final outcome was the extent of knowledge increase and the number of students with correct answers, expressed in percentage. Results: On average, 95.5% and 92.5% increase in knowledge was recorded among the medical students and PhD students respectively; an average of 4.5% medical students and 7.5% of PhD students recorded low scores in the post-test. As for the number of correct answers, the average results of the 22 set questions shared among the study groups were as follows: 15 questions were answered correctly more often by medical students, 6 were answered correctly more often by PhD students and only 1 question was correctly answered in the same average percentage by both the groups. Discussion: The results point to the need for proposing several key revisions. Among these include an exercise to be included in both curricula on online search for an article (Web of Science or Scopus without full text availability via link service, while instructions on manually creating bibliographic references shall be added to the PhD course. Additional search examples shall be added to the study materials and video records of in

    A flipped classroom approach has been implemented in an undergraduate fluid mechanics course. Students watch short on-line videos before class, participate in active in-class problem solving (in dyads), and complete individualized on-line quizzes weekly. In-class activities are designed to achieve a trifecta of: 1. developing problem solving skills, 2. learning subject content, and 3. developing inquiry skills. The instructor and assistants provide critical ``just-in-time tutoring'' during the in-class problem solving sessions. Comparisons are made with a simultaneous section offered in a traditional mode by a different instructor. Regression analysis was used to control for differences among students and to quantify the effect of the flipped fluid mechanics course. The dependent variable was the students' combined final examination and post-concept inventory scores and the independent variables were pre-concept inventory score, gender, major, course section, and (incoming) GPA. The R-square equaled 0.45 indicating that the included variables explain 45% of the variation in the dependent variable. The regression results indicated that if the student took the flipped fluid mechanics course, the dependent variable (i.e., combined final exam and post-concept inventory scores) was raised by 7.25 points. Interestingly, the comparison group reported significantly more often that their course emphasized memorization than did the flipped classroom group.

    Full Text Available Breaking bad news is one of the most burdensome tasks physicians face in their everyday practice. It becomes even more challenging in the context of HIV+ patients because of stigma and discrimination. The aim of the current study is to evaluate the quality of giving HIV seroconversion news according to SPIKES protocol. Numbers of 154 consecutive HIV+ patients from Imam Khomeini Hospital testing and counseling center were enrolled in this study. Patients were inquired about how they were given the HIV news and whether or not they received pre- and post-test counseling sessions. Around 51% of them were men, 80% had high school education, and 56% were employed. Regarding marital status, 32% were single, and 52% were married at the time of the interview. Among them, 31% had received the HIV news in a counseling center, and only 29% had pre-test counseling. SPIKES criteria were significantly met when the HIV news was given in an HIV counseling and testing center (P.value<0.05. Low coverage of HIV counseling services was observed in the study. SPIKES criteria were significantly met when the HIV seroconversion news was given in a counseling center. The need to further train staff to deliver HIV news seems a priority in the field of HIV care and treatment.

    The results of a post-test analysis of the integral system test P4, which has been executed in the PANDA facility at PSI in Switzerland within the framework of Work Package 2 of the TEPSS project are presented. The post-test analysis comprises an evaluation of the PANDA test P4 and a comparison of the test results with the results of simulations using the RELAPS/MOD3.2, TRAC-BF1, and MELCOR 1.8.4 codes. The PANDA test P4 has provided data about how trapped air released from the drywell later in the transient affects PCCS performance in an adequate manner. The well-defined measurements can serve as an important database for the assessment of thermal hydraulic system analysis codes, especially for conditions that could be met in passively operated advanced reactors, i.e. low pressure and small driving forces. Based on the analysis of the test data, the test acceptance criteria have been met. The test P4 has been successfully completed and the instrument readings were with the permitted ranges. The PCCs showed a favorable and robust performance and a wide margin for decay heat removal from the containment. The PANDA P4 test demonstrated that trapped air, released from the drywell later in the transient, only temporarily and only slightly affected the performance of the passive containment cooling system. The analysis of the results of the RELAPS code showed that the overall behaviour of the test has been calculated quite well with regards to pressure, mass flow rates, and pool boil-down. This accounts both for the pre-test and the post-test simulations. However, due to the one-dimensional, stacked-volume modeling of the PANDA DW, WW, and GDCS vessels, 3D-effects such as in-vessel mixing and recirculation could not be calculated. The post-test MELCOR simulation showed an overall behaviour that is comparable to RELAPS. However, MELCOR calculated almost no air trapping in the PCC tubes that could hinder the steam condensation rate. This resulted in lower calculated

    We have characterized a suite of samples taken subsequent to the end of the Spent Fuel Test - Climax by petrographic and microanalytical techniques and determined their mineral assemblage, modal properties, and mineral chemistry. The samples were obtained immediately adjacent to the canister borehole at a variety of depths and positions within the canister drift, as well as radially outward from each canister hole. This method of sampling allows variations in post-test mineralogic properties to be evaluated on the basis of (1) depth along a particular canister hole and (2) position within the canister drift, with respect to the heat and radiation sources, and with respect to the pre - test samples. In no case did we find any significant correlation between the mineralogical properties and variables listed above. In short, the Spent Fuel Test - Climax has produced no identifiable mineralogical response in the Climax quartz monzonite. 12 refs., 11 figs., 5 tabs

    1983-01-01

    The USNRC and the UKAEA have jointly funded a series of in-pile LOCA simulation experiments in the Canadian NRU reactor in order to secure further information on the thermal hydraulic and clad deformation response of PWR fuel rod bundles. Test MT-3 in the series was performed using reflood rate and rod internal pressure conditions specified by the UK nuclear industry. The parameters were selected to ensure the development of a near-isothermal clad temperature history during which zircaloy was required to balloon and rupture near the alpha-alpha/beta phase transition. Specification of the reflood rate conditions was assisted by the performance of a precursor test on an unpressurised rod bundle and by complementary application of appropriate thermal hydraulic analyses. Identification of the rod internal pressure needed to cause ballooning and rupture was achieved using a creep deformation model, BALLOON, in conjunction with the clad thermal history defined by the prior thermal hydraulic test. This paper presents the basis of the BALLOON analysis and describes its application in calculating the fill gas pressure for rods MT-3, their axial ballooning profile and the clad temperature at peak radial strain elevations.

    The Multi-professional Patient Safety Curriculum Guide was launched by the World Health Organization to develop a patient safety-friendly curriculum in health education. The aim of this study was to evaluate the impact of teaching related to two topics from the Patient Safety Curriculum Guide on student nurses' knowledge and attitudes toward patient safety. A pretest, posttest, nonexperimental design was used. Patient safety education questionnaires were distributed to a convenience sample of 181 nursing students before the intervention, and 141 questionnaires after the intervention in one university in the East of England. The intervention consisted of two face-to-face lectures and one facilitated group work discussion. Seventy-one responses from pre- and posttest stages were matched. Paired t test, McNemar's test, and frequency measures were used for data analysis. The findings suggest that there are statistically significant differences in the subscales of the error and patient safety and personal influence over safety. The differences in the students' answers on patient safety knowledge before and after the interventions were not statistically significant. Although the student nurses highly commended the teaching delivered in this study, the use of experimental design in future curriculum evaluation may provide a more complementary insight to the findings of this study.

    Coddington, P.

    2001-01-01

    As part of the PSI/HSK STARS project, pre-test calculations have been performed for a KKL turbine trip test at 109% power using the RETRAN-3D code. In this paper, we first present the results of these calculations, together with a description of the test and a comparison of the results with the measured plant data, and then discuss in more detail the differences between the pre-test results and the plant measurements, including the differences in the initial and boundary conditions, and how these differences influenced the calculated results. Finally, we comment on a series of post-test and sensitivity analyses, which were performed to resolve some of the discrepancies. The results of the pre-test (blind) calculations show good overall agreement with the experimental data, particularly for the maximum in the steam-line mass flow rate following the opening of the turbine bypass valves. This is of critical importance, since the steam-line flow has the least margin to the reactor scram limit. The agreement is especially good since the control rod banks used for the selected rod insertion were changed from those given in the test specification. Following a review of the comparison of the pre-test calculations with the measured data, several deficiencies in the RETRAN-3D model for KKL were identified and corrected as part of the post-test analysis. This allowed for both an improvement in the calculated results, and a deeper understanding of the behaviour of the turbine trip transient. (author)

    Full Text Available Abstract Background Hospital HIV care and public sexual health care (a Sexual Health Care Centre services were integrated to provide sexual health counselling and sexually transmitted infections (STIs testing and treatment (sexual health care to larger numbers of HIV patients. Services, need and usage were assessed using a patient perspective, which is a key factor for the success of service integration. Methods The study design was a one-group pre-test and post-test comparison of 447 HIV-infected heterosexual individuals and men who have sex with men (MSM attending a hospital-based HIV centre serving the southern region of the Netherlands. The intervention offered comprehensive sexual health care using an integrated care approach. The main outcomes were intervention uptake, patients’ pre-test care needs (n=254, and quality rating. Results Pre intervention, 43% of the patients wanted to discuss sexual health (51% MSM; 30% heterosexuals. Of these patients, 12% to 35% reported regular coverage, and up to 25% never discussed sexual health topics at their HIV care visits. Of the patients, 24% used our intervention. Usage was higher among patients who previously expressed a need to discuss sexual health. Most patients who used the integrated services were new users of public health services. STIs were detected in 13% of MSM and in none of the heterosexuals. The quality of care was rated good. Conclusions The HIV patients in our study generally considered sexual health important, but the regular counselling and testing at the HIV care visit was insufficient. The integration of public health and hospital services benefited both care sectors and their patients by addressing sexual health questions, detecting STIs, and conducting partner notification. Successful sexual health care uptake requires increased awareness among patients about their care options as well as a cultural shift among care providers.

    Substantial reductions in audit error rates observed over the past few years suggest eligibility workers have moved toward an eligibility compliance culture described by Bane and Ellwood. However, the results of this study indicate that social service caseworkers responded correctly to 49% of the targeted policy items at the pre-test stage and 68% at the post-test stage. Such findings provide preliminary support for the hypothesis that, in instances when caseworkers lack policy knowledge, they use their own discretion. Such a finding not only supports Lipsky's theory but also supports the notion that administrators should be encouraged to utilize 'mastery learning' procedures whereby caseworkers are retained in new-hire and follow-up training classes until they have mastered 100% of targeted policy information. Retention of caseworkers may also reduce federal and local audit errors and errors in crediting the reduction of caseloads to social service policies when in fact significant components of them have not been implemented (learned or utilized). And, most importantly, retention in training classes may increase the appropriate provision of services to the needy.

    Choreographer is a "moving target defense system", designed to protect against attacks aimed at IP addresses without corresponding domain name system (DNS) lookups. It coordinates actions between a DNS server and a Network Address Translation (NAT) device to regularly change which publicly available IP addresses' traffic will be routed to the protected device versus routed to a honeypot. More details about how Choreographer operates can be found in Section 2: Introducing Choreographer. Operational considerations for the successful deployment of Choreographer can be found in Section 3. The Testing & Evaluation (T&E) for Choreographer involved 3 phases: Pre-testing, Code Analysis, and Operational Testing. Pre-testing, described in Section 4, involved installing and configuring an instance of Choreographer and verifying it would operate as expected for a simple use case. Our findings were that it was simple and straightforward to prepare a system for a Choreographer installation as well as configure Choreographer to work in a representative environment. Code Analysis, described in Section 5, consisted of running a static code analyzer (HP Fortify) and conducting dynamic analysis tests using the Valgrind instrumentation framework. Choreographer performed well, such that only a few errors that might possibly be problematic in a given operating situation were identified. Operational Testing, described in Section 6, involved operating Choreographer in a representative environment created through EmulyticsTM . Depending upon the amount of server resources dedicated to Choreographer vis-á-vis the amount of client traffic handled, Choreographer had varying degrees of operational success. In an environment with a poorly resourced Choreographer server and as few as 50-100 clients, Choreographer failed to properly route traffic over half the time. Yet, with a well-resourced server, Choreographer handled over 1000 clients without missrouting. Choreographer

    For a successful design and analysis of Sodium cooled Fast Reactor (SFR), it is required to have a reliable and well-proven system analysis code. To achieve this purpose, KAERI is enhancing the modeling capability of MARS code by adding the SFR-specific models such as pressure drop model, heat transfer model and reactivity feedback model. This version of MARS-LMR will be used as a basic tool in the design and analysis of future SFR systems in Korea. Before wide application of MARS-LMR code, it is required to verify and validate the code models through analyses for appropriate experimental data or analytical results. The end-of-life test of Phenix reactor performed by the CEA provided a unique opportunity to have reliable test data which is very valuable in the validation and verification of a SFR system analysis code. The KAERI joined this international program of the analysis of Phenix end-of-life natural circulation test coordinated by the IAEA from 2008. The main test of natural circulation was completed in 2009. Before the test the KAERI performed the pre-test analysis based on the design condition provided by the CEA. Then, the blind post-test analysis was also performed based on the test conditions measured during the test before the CEA provide the final test results. Finally, the final post-test analysis was performed recently to predict the test results as accurate as possible. This paper introduces the modeling approach of the MARS-LMR used in the final post-test analysis and summarizes the major results of the analysis

    Variation in development methods of Pressure Ulcer Risk Assessment Instruments has led to inconsistent inclusion of risk factors and concerns about content validity. A new evidenced-based Risk Assessment Instrument, the Pressure Ulcer Risk Primary Or Secondary Evaluation Tool - PURPOSE-T was developed as part of a National Institute for Health Research (NIHR) funded Pressure Ulcer Research Programme (PURPOSE: RP-PG-0407-10056). This paper reports the pre-test phase to assess and improve PURPOSE-T acceptability, usability and confirm content validity. A descriptive study incorporating cognitive pre-testing methods and integration of service user views was undertaken over 3 cycles comprising PURPOSE-T training, a focus group and one-to-one think-aloud interviews. Clinical nurses from 2 acute and 2 community NHS Trusts, were grouped according to job role. Focus group participants used 3 vignettes to complete PURPOSE-T assessments and then participated in the focus group. Think-aloud participants were interviewed during their completion of PURPOSE-T. After each pre-test cycle analysis was undertaken and adjustment/improvements made to PURPOSE-T in an iterative process. This incorporated the use of descriptive statistics for data completeness and decision rule compliance and directed content analysis for interview and focus group data. Data were collected April 2012-June 2012. Thirty-four nurses participated in 3 pre-test cycles. Data from 3 focus groups, 12 think-aloud interviews incorporating 101 PURPOSE-T assessments led to changes to improve instrument content and design, flow and format, decision support and item-specific wording. Acceptability and usability were demonstrated by improved data completion and appropriate risk pathway allocation. The pre-test also confirmed content validity with clinical nurses. The pre-test was an important step in the development of the preliminary PURPOSE-T and the methods used may have wider instrument development application

    Full Text Available The efficacy of methods like e-learning as a supplement to traditional face-to-face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of  the virtual school of Tehran University of Medical Sciences called “SARMAD” to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD during 6 weeks and discussed. Then, students participated in a post-test. Students’ perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001; but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128. In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

    A patient-education program was designed by members of the Neurology Nursing Service. The program was designed to provide patients with diabetes insipidus with the information needed to help them manage their condition in the hospital and at home upon discharge. The program was approved by the Nursing Department's Patient Education Committee. The nurses worked closely with the hospital's patient-education coordinator and television-production staff to produce a videotape for educating patients about managing diabetes insipidus. A literature review of patient-education resources on diabetes insipidus revealed that no materials were available in either audiovisual or print media. The program utilized the multi-media approach of a videotape that was shown over closed-circuit television and a booklet outlining the salient points of the television program. All patients utilizing the program have been pre-tested and post-tested to assess their achievement of behavioral objectives.

    This article discusses about market segmentation and targeting as a first step in pre-test market of a new technology. The benefits of targeting towards pre-test market are pre-test market can be conducted to focus on selected target markets so there is no bias during the pre-test market. In determining the target market then do some surveys to identify the state of market in the future, so that the marketing process is not misplaced. Lithium ion battery which is commercialized through start-up companies is the case study. This start-up companies must be able to respond the changes and bring in customers as well as maintain them so that companies can survive and evolve to achieve its objectives. The research aims to determine market segments and target market effectively. Marketing strategy (segmentation and targeting) is used to make questionnaire and cluster analysis in data processing. Respondents were selected by purposive sampling and have obtained data as many as 80 samples. As the results study, there are three segments for lithium ion battery with their own distinguished characteristics and there are two segments that can be used as the target market for the company.

    To assess the utility of a multiple-encounter in-situ (MEIS) simulation as an orientation tool for multidisciplinary staff prior to opening a new paediatric emergency service. A single-group pretest/post-test study was conducted. During the MEIS simulation, multidisciplinary staff with participant or observer roles managed eight children (mannequins) who attended triage with their parent/guardians (clinical facilitators) for a range of emergency presentations (structured scenarios designed to represent the expected range of presentations plus test various clinical pathways/systems). Participants were debriefed to explore clinical, systems and crisis-resource management issues. Participants also completed a pre-intervention and post-intervention questionnaire comprising statements about role confidence and orientation adequacy. Pre-test and post-test results were analysed using t-test and Wilcoxon signed rank test. Eighty-nine staff participated in the MEIS simulation, with the majority completing the pre-simulation and post-simulation questionnaire. There was a significant improvement in post-intervention versus pre-intervention Likert scores for role confidence and orientation adequacy (p=0.001 and simulation was of utility in orientation of staff, at least with respect to self-reported role confidence and orientation adequacy. Its effectiveness in practice or compared with other orientation techniques was not assessed, but it did identify several flaws in planned systems allowing remediation prior to opening.

    Full Text Available A comprehensive search of PubMed and Embase was performed in January 2015 to examine the available literature on validated diagnostic models of the pre-test probability of stable coronary artery disease and to describe the characteristics of the models. Studies that were designed to develop and validate diagnostic models of pre-test probability for stable coronary artery disease were included. Data regarding baseline patient characteristics, procedural characteristics, modeling methods, metrics of model performance, risk of bias, and clinical usefulness were extracted. Ten studies involving the development of 12 models and two studies focusing on external validation were identified. Seven models were validated internally, and seven models were validated externally. Discrimination varied between studies that were validated internally (C statistic 0.66-0.81 and externally (0.49-0.87. Only one study presented reclassification indices. The majority of better performing models included sex, age, symptoms, diabetes, smoking, and hyperlipidemia as variables. Only two diagnostic models evaluated the effects on clinical decision making processes or patient outcomes. Most diagnostic models of the pre-test probability of stable coronary artery disease have had modest success, and very few present data regarding the effects of these models on clinical decision making processes or patient outcomes.

    Silin, D.B.; Tsang, C.-F.

    2003-01-01

    We propose to use regular monitoring data from a production or injection well for estimating the formation hydraulic properties in the vicinity of the wellbore without interrupting the operations. In our approach, we select a portion of the pumping data over a certain time interval and then derive our conclusions from analysis of these data. A distinctive feature of the proposed approach differing it form conventional methods is in the introduction of an additional parameter, an effective pre-test pumping rate. The additional parameter is derived based on a rigorous asymptotic analysis of the flow model. Thus, we account for the non-uniform pressure distribution at the beginning of testing time interval caused by pre-test operations at the well. By synthetic and field examples, we demonstrate that deviation of the matching curve from the data that is usually attributed to skin and wellbore storage effects, can also be interpreted through this new parameter. Moreover, with our method, the data curve is matched equally well and the results of the analysis remain stable when the analyzed data interval is perturbed, whereas traditional methods are sensitive to the choice of the data interval. A special efficient minimization procedure has been developed for searching the best fitting parameters. We enhanced our analysis above with a procedure of estimating ambient reservoir pressure and dimensionless wellbore radius. The methods reported here have been implemented in code ODA (Operations Data Analysis). A beta version of the code is available for free testing and evaluation to interested parties

  7. Pre-test CFD Calculations for a Bypass Flow Standard Problem

    Energy Technology Data Exchange (ETDEWEB)

    Rich Johnson

    2011-11-01

    The bypass flow in a prismatic high temperature gas-cooled reactor (HTGR) is the flow that occurs between adjacent graphite blocks. Gaps exist between blocks due to variances in their manufacture and installation and because of the expansion and shrinkage of the blocks from heating and irradiation. Although the temperature of fuel compacts and graphite is sensitive to the presence of bypass flow, there is great uncertainty in the level and effects of the bypass flow. The Next Generation Nuclear Plant (NGNP) program at the Idaho National Laboratory has undertaken to produce experimental data of isothermal bypass flow between three adjacent graphite blocks. These data are intended to provide validation for computational fluid dynamic (CFD) analyses of the bypass flow. Such validation data sets are called Standard Problems in the nuclear safety analysis field. Details of the experimental apparatus as well as several pre-test calculations of the bypass flow are provided. Pre-test calculations are useful in examining the nature of the flow and to see if there are any problems associated with the flow and its measurement. The apparatus is designed to be able to provide three different gap widths in the vertical direction (the direction of the normal coolant flow) and two gap widths in the horizontal direction. It is expected that the vertical bypass flow will range from laminar to transitional to turbulent flow for the different gap widths that will be available.

    Shayer, Michael; Adhami, Mundher

    2010-09-01

    In the context of the British Government's policy directed on improving standards in schools, this paper presents research on the effects of a programme intended to promote the cognitive development of children in the first 2 years of primary school (Y1 & 2, aged 5-7 years). The programme is based on earlier work dealing with classroom-based interventions with older children at both primary and secondary levels of schooling. The hypothesis tested is that it is possible to increase the cognitive ability of children by assisting teachers towards that aim in the context of mathematics. A corollary hypothesis is that such an increase would result in an increase in long-term school achievement. The participants were 8 teachers in one local education authority (LEA) and 10 teachers in another. Data were analysed on 275 children present at Year 1 pre-test in 2002 and at long-term Key Stage 2 post-test in 2008. Two intervention methods were employed: a Y1 set of interactive activities designed around Piagetian concrete operational schemata, and mathematics lessons in both Y1 and Y2 designed from a theory-base derived from both Piaget and Vygotsky. At post-test in 2004, the mean effect sizes for cognitive development of the children - assessed by the Piagetian test Spatial Relations - were 0.71 SD in one LEA and 0.60 SD in the other. Five classes achieved a median increase of 1.3 SD. The mean gains over pre-test in 2002 for all children in Key Stage 1 English in 2004 were 0.51 SD, and at Key Stage 2 English in 2008 - the long-term effect - were 0.36 SD, an improvement of 14 percentile points. The main hypothesis was supported by the data on cognitive development. The corollary hypothesis is supported by the gains in English. The implications of this study are that relative intelligence can be increased and is not fixed, and that children can be led into collaborating with each other to the benefit of their own thinking, and that there does exist a theory-based methodology

    Hypothetical Small Break Loss Of Coolant Accident is identified as one of the most severe transients leading to a potential huge Pressurized Thermal Shock on the Reactor Pressure Vessel (RPV). This may result in two-phase flow configurations in the cold legs, according to the operating conditions, and to reliably assess the RPV wall integrity, advanced two-phase flow simulations are required. Related needs in development and/or validation of these advanced models are important, and the on-going TOPFLOW-PTS experimental program was designed to provide a well documented data base to meet these needs. This paper focuses on pre-test NEPTUNE{sub C}FD simulations of TOPFLOW-PTS experiments; these simulations were performed to (i) help in the definition of the test matrix and test procedure, and (ii) check the presence of the different key physical phenomena at the mock-up scale.

    Graduate and post-graduate education for health professionals is increasingly delivered in an e-learning environment, where automated, continuous formative testing with integrated feedback can guide students' self-assessment and learning. Asking students to rate the certainty they assign to the correctness of their answers to test questions can potentially provide deeper insights into the success of teaching, with test results informing course designers whether learning outcomes have been achieved. It may also have implications for decision making in clinical practice. A study of pre-and post-tests for five study modules was designed to evaluate the teaching and learning within a pharmacotherapeutic course in an online postgraduate clinical pharmacy program. Certainty based marking of multiple choice questions (MCQ) was adapted for formative pre- and post-study module testing by asking students to rate their certainty of correctness of MCQ answers. Paired t-tests and a coding scheme were used to analyse changes in answers and certainty between pre-and post-tests. A survey evaluated students' experience with the novel formative testing design. Twenty-nine pharmacists enrolled in the postgraduate program participated in the study. Overall 1315 matched pairs of MCQ answers and certainty ratings between pre- and post-module tests were available for evaluation. Most students identified correct answers in post-tests and increased their certainty compared to pre-tests. Evaluation of certainty ratings in addition to correctness of answers identified MCQs and topic areas for revision to course designers. A survey of students showed that assigning certainty ratings to their answers assisted in structuring and focusing their learning throughout online study modules, facilitating identification of areas of uncertainty and gaps in their clinical knowledge. Adding certainty ratings to MCQ answers seems to engage students with formative testing and feedback and focus their

    With the increasing costs of physics experiments and simultaneous increase in availability and maturity of computational tools it is not surprising that computational fluid dynamics (CFD) is playing an increasingly important role, not only in post-test investigations, but also in the early stages of experimental planning. This paper describes a CFD-based effort executed in close collaboration between computational fluid dynamicists and experimentalists to develop a virtual experiment during the early planning stages of the Enhanced Injection and Mixing project at NASA Langley Research Center. This projects aims to investigate supersonic combustion ramjet (scramjet) fuel injection and mixing physics, improve the understanding of underlying physical processes, and develop enhancement strategies and functional relationships relevant to flight Mach numbers greater than 8. The purpose of the virtual experiment was to provide flow field data to aid in the design of the experimental apparatus and the in-stream rake probes, to verify the nonintrusive measurements based on NO-PLIF, and to perform pre-test analysis of quantities obtainable from the experiment and CFD. The approach also allowed for the joint team to develop common data processing and analysis tools, and to test research ideas. The virtual experiment consisted of a series of Reynolds-averaged simulations (RAS). These simulations included the facility nozzle, the experimental apparatus with a baseline strut injector, and the test cabin. Pure helium and helium-air mixtures were used to determine the efficacy of different inert gases to model hydrogen injection. The results of the simulations were analyzed by computing mixing efficiency, total pressure recovery, and stream thrust potential. As the experimental effort progresses, the simulation results will be compared with the experimental data to calibrate the modeling constants present in the CFD and validate simulation fidelity. CFD will also be used to

    College-level teaching of Earth science concepts typically assumes students have a supporting-science conceptual framework and skills for visualizing in three dimensions. The Geoscience Concept Inventory (GCI) is an assessment instrument for measuring learning that includes questions from most geologic sub-disciplines, as well as some from supporting science areas. Several questions rely on the ability to interpret two and three dimensional situations. Nationwide pre- and post-testing of introductory Earth science courses with the Geoscience Concept Inventory show little gain for many of its questions. Analysis of matched tests shows that students are typically switching between wrong answers. Of the 22 GCI questions that showed a normalized gain of students have high conceptual mobility. These results also pertain to the high pre-test students, suggesting that little conceptual entrenchment occurs for many students enrolled in entry-level courses. We suggest that students may have difficulty settling on a correct geological conception because of the shaky supporting-science underpinnings upon which these ideas are built. These results prompt the following questions; when do our hydrology and other Earth science students learn fundamental science concepts, and what role does an introductory course play in this learning? We suggest that longitudinal studies are needed for time periods longer than a semester, and that more attention be paid to when conceptual change occurs for our advanced learners.

    Although the process of diagnosing invariably begins with a heuristic, we encourage our learners to support their diagnoses by analytical cognitive processes, such as Bayesian reasoning, in an attempt to mitigate the effects of heuristics on diagnosing. There are, however, limited data on the use ± impact of Bayesian reasoning on the accuracy of disease probability estimates. In this study our objective was to explore whether Internal Medicine residents use a Bayesian process to estimate disease probabilities by comparing their disease probability estimates to literature-derived Bayesian post-test probabilities. We gave 35 Internal Medicine residents four clinical vignettes in the form of a referral letter and asked them to estimate the post-test probability of the target condition in each case. We then compared these to literature-derived probabilities. For each vignette the estimated probability was significantly different from the literature-derived probability. For the two cases with low literature-derived probability our participants significantly overestimated the probability of these target conditions being the correct diagnosis, whereas for the two cases with high literature-derived probability the estimated probability was significantly lower than the calculated value. Our results suggest that residents generate inaccurate post-test probability estimates. Possible explanations for this include ineffective application of Bayesian reasoning, attribute substitution whereby a complex cognitive task is replaced by an easier one (e.g., a heuristic), or systematic rater bias, such as central tendency bias. Further studies are needed to identify the reasons for inaccuracy of disease probability estimates and to explore ways of improving accuracy.

    Existing methods to calculate pre-test probability of obstructive coronary artery disease (CAD) have been established using selected high-risk patients who were referred to conventional coronary angiography. The purpose of this study is to develop and validate our new method for pre-test probability of obstructive CAD using patients who underwent coronary CT angiography (CTA), which could be applicable to a wider range of patient population. Using consecutive 4137 patients with suspected CAD who underwent coronary CTA at our institution, a multivariate logistic regression model including clinical factors as covariates calculated the pre-test probability (K-score) of obstructive CAD determined by coronary CTA. The K-score was compared with the Duke clinical score using the area under the curve (AUC) for the receiver-operating characteristic curve. External validation was performed by an independent sample of 319 patients. The final model included eight significant predictors: age, gender, coronary risk factor (hypertension, diabetes mellitus, dyslipidemia, smoking), history of cerebral infarction, and chest symptom. The AUC of the K-score was significantly greater than that of the Duke clinical score for both derivation (0.736 vs. 0.699) and validation (0.714 vs. 0.688) data sets. Among patients who underwent coronary CTA, newly developed K-score had better pre-test prediction ability of obstructive CAD compared to Duke clinical score in Japanese population.

    Full Text Available Abstract Background Two trials were conducted to compare emergency department patient comprehension of rapid HIV pre-test information using different methods to deliver this information. Methods Patients were enrolled for these two trials at a US emergency department between February 2005 and January 2006. In Trial One, patients were randomized to a no pre-test information or an in-person discussion arm. In Trial Two, a separate group of patients were randomized to an in-person discussion arm or a Tablet PC-based video arm. The video, "Do you know about rapid HIV testing?", and the in-person discussion contained identical Centers for Disease Control and Prevention-suggested pre-test information components as well as information on rapid HIV testing with OraQuick®. Participants were compared by information arm on their comprehension of the pre-test information by their score on a 26-item questionnaire using the Wilcoxon rank-sum test. Results In Trial One, 38 patients completed the no-information arm and 31 completed the in-person discussion arm. Of these 69 patients, 63.8% had twelve years or fewer of formal education and 66.7% had previously been tested for HIV. The mean score on the questionnaire for the in-person discussion arm was higher than for the no information arm (18.7 vs. 13.3, p ≤ 0.0001. In Trial Two, 59 patients completed the in-person discussion and 55 completed the video arms. Of these 114 patients, 50.9% had twelve years or fewer of formal education and 68.4% had previously been tested for HIV. The mean score on the questionnaire for the video arm was similar to the in-person discussion arm (20.0 vs. 19.2; p ≤ 0.33.

    2014-01-01

    Background Measurement of toe and ankle blood pressure is commonly used to evaluate peripheral vascular status, yet the pre-test rest period is inconsistent in published studies and among practitioners, and could affect results. The aim of this systematic review is to evaluate all research that has investigated the effect of different periods of pre-test rest on toe and ankle systolic blood pressure. Methods The following databases were searched up to April 2012: Medline (from 1946), EMBASE (from 1947), CINAHL (from 1937), and Cochrane Central Register of Controlled Trials (CENTRAL) (from 1800). No language or publication restrictions were applied. Eighty-eight content experts and researchers in the field were contacted by email to assist in the identification of published, unpublished, and ongoing studies. Studies evaluating the effect of two or more pre-test rest durations on toe or ankle systolic blood pressure were eligible for inclusion. No restrictions were placed on participant characteristics or the method of blood pressure measurement. Outcomes included toe or ankle systolic blood pressure and adverse effects. Abstracts identified from the search terms were independently assessed by two reviewers for potential inclusion. Results 1658 abstracts were identified by electronic searching. Of the 88 content experts and researchers in the field contacted by email a total of 33 replied and identified five potentially relevant studies. No studies were eligible for inclusion. Conclusions There is no evidence of the effect of different periods of pre-test rest duration on toe and ankle systolic blood pressure measurements. Rigorous trials evaluating the effect of different durations of pre-test rest are required to direct clinical practice and research. PMID:24708870

    Genetic carrier screening, prenatal screening for aneuploidy and prenatal diagnostic testing have expanded dramatically over the past two decades. Driven in part by powerful market forces, new complex testing modalities have become available after limited clinical research. The responsibility for offering these tests lies primarily on the obstetrical care provider, and has become more burdensome as the number of testing options expands. Genetic testing in pregnancy is optional, and decisions about undergoing tests, as well as follow-up testing, should be informed and based on individual patients’ values and needs. Careful pre- and post-test counseling is central to supporting informed decision-making. This article explores three areas of technical expansion in genetic testing: expanded carrier screening, non-invasive prenatal screening for fetal aneuploidies using cell-free DNA, and diagnostic testing using fetal chromosomal microarray testing, and provides insights aimed at enabling the obstetrical practitioner to better support patients considering these tests.

    inhomogeneous, in fact high velocity values occur beside the loop positions, and not below the inlet nozzles, which indicates the presence of recirculation areas or stagnant zones. Regarding the flow field and mixing at the core inlet, it has been shown that the mass flow rate distribution is more or less homogenous over the core diameter due to the lower plenum internals, the perturbed sector covers more or less one fourth of the core; a sharp sector formation like in western 4-loop reactors appears, weak mixing zones appear (around 99.7% of the unperturbed concentration). In most cases, the sensitivity analyses performed did not show any appreciable dependence of the results with respect to the addressed parameters. A three loop operation was chosen to show the differences of the flow and mixing behavior compared to the four loop operation. An extensive experimental program is now running, aimed at studying different flow conditions in the reactor mock up, such as the start-up of the 1st coolant pump or natural circulation conditions with density differences of the primary coolant. Pre and post test CFD simulations are being carried out for code validation and for a deeper understanding of the flow and mixing behavior in the WWER-1000 reactor also in the future of the project (Authors)

    Highlights: • Thermal-hydraulic system codes and CFD tools are coupled. • Pre-test calculations for the TALL-3D facility are performed. • Complex flow and heat transfer phenomena are modeled. • Comparative analyses have been performed. - Abstract: The system thermal-hydraulic (STH) code ATHLET was coupled with the commercial 3D computational fluid dynamics (CFD) software package ANSYS CFX to improve ATHLET simulation capabilities for flows with pronounced 3D phenomena such as flow mixing and thermal stratification. Within the FP7 European project THINS (Thermal Hydraulics of Innovative Nuclear Systems), validation activities for coupled thermal-hydraulic codes are being carried out. The TALL-3D experimental facility, operated by KTH Royal Institute of Technology in Stockholm, is designed for thermal-hydraulic experiments with lead-bismuth eutectic (LBE) coolant at natural and forced circulation conditions. GRS carried out pre-test simulations with ATHLET–ANSYS CFX for the TALL-3D experiment T01, while KTH scientists perform these analyses with the coupled code RELAP5/STAR CCM+. In the experiment T01 the main circulation pump is stopped, which leads to interesting thermal-hydraulic transient with local 3D phenomena. In this paper, the TALL-3D behavior during T01 is analyzed and the results of the coupled pre-test calculations, performed by GRS (ATHLET–ANSYS CFX) and KTH (RELAP5/STAR CCM+) are directly compared.

    Prior research states that the use of living animals in the classroom leads to a higher knowledge but those previous studies have methodological and statistical problems. We applied a meta-analysis and developed a treatment-control study in a middle school classroom. The treatments (film vs. living animal) differed only by the presence of the living animal. Both treatments were based on the self-determination theory. More than 400 pupils filled in pre-test, post-test and two follow-up-tests (with a delay of 6-8 weeks and 7-8 months). After each lesson, pupils rated the lesson on a short intrinsic motivation scale. In the meta-analysis, we found that the living animal treatments significantly scored better than a control group, but not when comparing living animals with alternative treatments. In the treatment-control study, both treatments led to a significant increase in knowledge but there were no differences between film and living animal treatment. Pre-test and previous grading had a significant influence on post- and both follow-up tests. In the mouse lesson, pupils of the living animal group showed higher values in interest and competence and lower values in pressure. Interest and competence correlated positively with achievement, while pressure correlated negatively.

    Three copper electrodes have been exposed for eight years in the outer section of the Prototype Repository at Aespoe. The electrodes were installed in the upper bentonite block of deposition hole 5 in May 2003. Most of the time the temperature of the electrodes has been somewhat below 35 deg C. The electrodes were retrieved for post-test examination in September 2011. This report presents results from electrochemical measurements and the post-test examination of one of the electrodes. The corrosion potential of the examined copper electrode was -40 mV SHE (2011-02-04) when part of the concrete plug to the outer section of the repository had been removed and made measurements possible. When the back-fill in the deposition tunnel had been removed it was 25 mV SHE (2011-09-12). Finally, before letting loose the copper electrode from the retrieved bentonite block, the corrosion potential was found to be 165 mV SHE (2011-11-15) being a sign of air ingress to the electrode/ bentonite interface. It was immediately obvious from the appearance of the copper electrode, when part of the surrounding bentonite had been removed, that both Cu(I) and Cu(II) corrosion products existed on the electrode surface. X-ray diffraction measurements also verified the presence of cuprite, Cu 2 O, and malachite, Cu 2 (OH) 2 CO 3 , on the electrode; however, paratacamite, Cu 2 (OH) 3 Cl, was not found. The performed Fourier transform infrared and Raman spectroscopy confirmed these observations. The corrosion product film, of which cuprite is the main part, was quite uneven and porous. No unmistakable signs of pitting have been found. The appearance of the copper electrode reminded of the coupons from the retrieved LOT test parcels, but was different from the appearance of the surface on the full-size canisters. For the latter blue-green Cu(II) corrosion products have not or only rarely been observed from visual examination immediately after removing the surrounding bentonite. Differences that

    High-temperature heat pipes are being evaluated for use in energy conversion applications such as fuel cells, gas turbine re-combustors, Stirling cycle heat sources; and with the resurgence of space nuclear power both as reactor heat removal elements and as radiator elements. Long operating life and reliable performance are critical requirements for these applications. Accordingly, long-term materials compatibility is being evaluated through the use of high-temperature life test heat pipes. Thermacore, Inc., has carried out a sodium heat pipe 10-year life test to establish long-term operating reliability. Sodium heat pipes have demonstrated favorable materials compatibility and heat transport characteristics at high operating temperatures in air over long time periods. A representative one-tenth segment Stirling Space Power Converter heat pipe with an Inconel 718 envelope and a stainless steel screen wick has operated for over 87,000 hr (10 years) at nearly 700 C. These life test results have demonstrated the potential for high-temperature heat pipes to serve as reliable energy conversion system components for power applications that require long operating lifetime with high reliability. Detailed design specifications, operating history, and post-test analysis of the heat pipe and sodium working fluid are described. Lessons learned and future life test plans are also discussed.

    The Jewish community has traditionally taken ownership of its health, and has taken great strides to raise awareness about genetic issues that affect the community, such as Tay-Sachs disease and Hereditary Breast and Ovarian Cancer syndrome. Thanks in part to these heightened awareness efforts, many Orthodox Jewish individuals are now using genetics services as they begin to plan their families. Due to unique cultural and religious beliefs and perceptions, the Orthodox Jewish patients who seek genetic counseling face many barriers to a successful counseling session, and often seek the guidance of programs such as the Program for Jewish Genetic Health (PJGH). In this article, we present clinical vignettes from the PJGH's clinical affiliate, the Reproductive Genetics practice at the Montefiore Medical Center. These cases highlight unique features of contemporary premarital counseling and screening within the Orthodox Jewish Community, including concerns surrounding stigma, disclosure, "marriageability," the use of reproductive technologies, and the desire to include a third party in decision making. Our vignettes demonstrate the importance of culturally-sensitive counseling. We provide strategies and points to consider when addressing the challenges of pre- and post-test counseling as it relates to genetic testing in this population.

    Electrochemical performance is often limited by surface and interfacial reactions at the electrodes. However, routine handling of samples can alter the very surfaces that are the object of study. Our approach combines standardized testing of batteries with sample harvesting under inert atmosphere conditions. Cells of different formats are disassembled inside an Argon glove box with controlled water and oxygen concentrations below 2 ppm. Cell components are characterized in situ, guaranteeing that observed changes in physicochemical state are due to electrochemical operation, rather than sample manipulation. We employ a complementary set of spectroscopic, microscopic, electrochemical and metallographic characterization to obtain a complete picture of cell degradation mechanisms. The resulting information about observed degradation mechanisms is provided to materials developers, both academic and industrial, to suggest new strategies and speed up the Research & Development cycle of Li-ion and related technologies. This talk will describe Argonne's post-test analysis laboratory, with an emphasis on capabilities and opportunities for collaboration. Cell disassembly, sample harvesting procedures and recent results will be discussed. This work was performed under the auspices of the U.S. Department of Energy, Office of Vehicle Technologies, Hybrid and Electric Systems, under Contract No. DE-AC02-06CH11357.

    FOREVER (Failure Of Reactor Vessel Rentention) experiments have been carried out in order to simulate the behaviour the lower head of a reactor pressure vessel under the conditions of a depressurized core melt down scenario. In particular the creep behaviour and the vessel failure mode have been investigated. Metallographic post test investigations have complemented the experimental programme. Samples of different height positions of the vessel of the FOREVER-C1 and -C2 experiments were metallographically examined and characteristic microstructural appearances were identified. Additionally samples with ineffected microstructure were annealed at different temperatures and cooled by different rates and afterwards investigated. In this way the microstructural effects of the temperature regime, the thermomechanical loads and the environmental attack could be characterized. Remarkable effects were characteristic for the FOREVER-C2 experiment where the highest-loaded region below the welding joint reached temperatures of approx. 1100 C and a strong creep damage occurred. In the FOREVER-C1 experiment creep damage could not be observed and the maximum temperature did not exceed 900 C. Environmental attack generated decarburization and oxidation but the effect was restricted to a narrow surface layer. There was almost no chemical interaction between the oxidic melt and the vessel material. (orig.)

    The Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) concept, developed by The Boeing Company, has been extensively studied as part of the National Aeronautics and Space Administration's (NASA s) Environmentally Responsible Aviation (ERA) Program. The PRSEUS concept provides a light-weight alternative to aluminum or traditional composite design concepts and is applicable to traditional-shaped fuselage barrels and wings, as well as advanced configurations such as a hybrid wing body or truss braced wings. Therefore, NASA, the Federal Aviation Administration (FAA) and The Boeing Company partnered in an effort to assess the performance and damage arrestments capabilities of a PRSEUS concept panel using a full-scale curved panel in the FAA Full-Scale Aircraft Structural Test Evaluation and Research (FASTER) facility. Testing was conducted in the FASTER facility by subjecting the panel to axial tension loads applied to the ends of the panel, internal pressure, and combined axial tension and internal pressure loadings. Additionally, reactive hoop loads were applied to the skin and frames of the panel along its edges. The panel successfully supported the required design loads in the pristine condition and with a severed stiffener. The panel also demonstrated that the PRSEUS concept could arrest the progression of damage including crack arrestment and crack turning. This paper presents the nonlinear post-test analysis and correlation with test results for the curved PRSEUS panel. It is shown that nonlinear analysis can accurately calculate the behavior of a PRSEUS panel under tension, pressure and combined loading conditions.

    Genetic carrier screening, prenatal screening for aneuploidy, and prenatal diagnostic testing have expanded dramatically over the past 2 decades. Driven in part by powerful market forces, new complex testing modalities have become available after limited clinical research. The responsibility for offering these tests lies primarily on the obstetrical care provider and has become more burdensome as the number of testing options expands. Genetic testing in pregnancy is optional, and decisions about undergoing tests, as well as follow-up testing, should be informed and based on individual patients' values and needs. Careful pre- and post-test counseling is central to supporting informed decision-making. This article explores three areas of technical expansion in genetic testing: expanded carrier screening, non-invasive prenatal screening for fetal aneuploidies using cell-free DNA, and diagnostic testing using fetal chromosomal microarray testing, and provides insights aimed at enabling the obstetrical practitioner to better support patients considering these tests.

    2013-01-01

    Objective The emergence of evidence suggests that student nurses commonly exhibit concerns about their lack of knowledge of organ donation and transplantation. Formal training about organ donation has been shown to positively influence attitude, encourage communication and registration behaviours and improve knowledge about donor eligibility and brain death. The focus of this study was to determine the attitude and behaviour of student nurses and to assess their level of knowledge about organ donation after a programme of study. Design A quantitative questionnaire was completed before and after participation in a programme of study using a pretest–post-test design. Setting Participants were recruited from a University based in Northern Ireland during the period from February to April 2011. Participants 100 preregistration nurses (female : male=96 : 4) aged 18–50 years (mean (SD) 24.3 (6.0) years) were recruited. Results Participants’ knowledge improved over the programme of study with regard to the suitability of organs that can be donated after death, methods available to register organ donation intentions, organ donation laws, concept of brain death and the likelihood of recovery after brain death. Changes in attitude postintervention were also observed in relation to participants’ willingness to accept an informed system of consent and with regard to participants’ actual discussion behaviour. Conclusions The results provide support for the introduction of a programme that helps inform student nurses about important aspects of organ donation. PMID:24381257

    Due to age dependent organ manifestation, diagnosis of Marfan syndrome (MFS) is a challenge, especially in childhood. It is important to identify children at risk of MFS as soon as possible to direct those to appropriate treatment but also to avoid stigmatization due to false diagnosis. We published the Kid-Short Marfan Score (Kid-SMS) in 2012 to stratify the pre-test probability of MFS in childhood. Hence we now evaluate the predictive performance of Kid-SMS in a new cohort of children. We prospectively investigated 106 patients who were suspected of having MFS. At baseline, children were examined according to Kid-SMS. At baseline and follow-up visit, diagnosis of MFS was established or rejected using standard current diagnostic criteria according to the revised Ghent Criteria (Ghent-2). At baseline 43 patients were identified with a risk of MFS according to Kid-SMS whereas 21 patients had Ghent-2 diagnosis of MFS. Sensitivity was 100%, specificity 77%, negative predictive value 100% and Likelihood ratio of Kid-SMS 4.3. During follow-up period, three other patients with a stratified risk for MFS were diagnosed according to Ghent-2. We confirm very good predictive performance of Kid-SMS with excellent sensitivity and negative predictive value but restricted specificity. Kid-SMS avoids stigmatization due to diagnosis of MFS and thus restriction to quality of life. Especially outpatient pediatricians and pediatric cardiologists can use it for primary assessment.

    Suomen Malmi Oy (Smoy) core drilled four drillholes for bentonite buffer pre-test in ONKALO at Eurajoki, Olkiluoto in July 2010. The identification numbers of the holes are ONK-PP264..267, and the lengths of the drillholes are approximately 4.30 metres each. The drillholes are 75.7 mm by diameter. The drillholes were drilled in a niche at access tunnel chainage 1475. The hydraulic DE 130 drilling rig was used for the work. The drilling water was taken from the ONKALO drilling water pipeline and premixed sodium fluorescein was used as a label agent in the drilling water. In addition to drilling, the drillcores were logged and reported by geologist. Geological logging included the following parameters: lithology, foliation, fracture parameters, fractured zones, core loss, weathering, fracture frequency, RQD and rock quality. The main rock type in the drillholes is pegmatitic granite. The average fracture frequency in the drill cores is 4.0 pcs / m and the average RQD value 94.2 %. (orig.)

    The aim of the present study was to measure the leadership and management abilities of graduates who had completed a master's degree in nursing. A number of reports have recommended that leadership competencies be integrated into education programmes for nurses at a master's level. In spite of the growth in the number of graduates from higher degrees in nursing, there is a paucity of evidence on the management and leadership outcomes that develop as a result of undertaking a master's degree. A cross-sectional survey using a retrospective pre-test design was used to measure self-reported leadership and management outcomes from the graduates' educational programmes. Results found that graduates had gained significantly on their ability to change practice, communicate and work as part of a team and to problem solve as an outcome of completing a master's degree in nursing. Graduates make substantial gains in leadership and management capabilities as a consequence of their higher degree. These capabilities are necessary as nurses take the lead in many areas of healthcare. The masters in nursing degree now has a pivotal role in providing effective continuing education to the nursing profession; especially for those who occupy or intend to occupy senior positions within clinical, management or education branches of the profession. © 2011 Blackwell Publishing Ltd.

    Full Text Available We analyzed the effectiveness of two psychological therapies to treat depression in the Culiacan population, Mexico. According to criteria of MINI (international Neuropsychiatric interview, 30 individuals from a total of 300 were selected and diagnosed with some kind of depression. Patients were divided in three groups: 1 treatment with hypnosis therapy, 2 treatment with Gestalt-hypnosis therapy, and 3 control group. Before and after the treatments the Beck Anxiety Inventory (BAI was applied to know the depression level of the analyzed groups. The results show that the three groups were presenting a moderated level of depression. The groups under hypnosis therapy and Gestalt-hypnosis therapy show statistical differences between pre-test and post-test. The hypnosis therapy shows significant statistic differences to treat depression with respect to the other two groups. In conclusion, the therapeutic hypnosis is an effective treatment and has relevance to treat depression, while other therapeutic treatments tend to be slow and with minor result. This study is the first of this kind carried out in Culiacan in Sinaloa, Mexico.

    One of the most common symptoms observed in patients with dementia is agitation, and several non-pharmacological treatments have been used to control this symptom. However, because of limitations in research design, the benefit of non-pharmacological treatments has only been demonstrated in certain cases. The purpose of this study was to compare aroma-acupressure and aromatherapy with respect to their effects on agitation in patients with dementia. In this experimental study, the participants were randomly assigned to three groups: 56 patients were included in the aroma-acupressure group, 73 patients in the aromatherapy group, and 57 patients in the control group who received daily routine as usual without intervention. The Cohen-Mansfield Agitation Inventory (CMAI) scale and the heart rate variability (HRV) index were used to assess differences in agitation. The CMAI was used in the pre-test, post-test and post-three-week test, and the HRV was used in the pre-test, the post-test and the post-three-week test as well as every week during the four-week interventions. The CMAI scores were significantly lower in the aroma-acupressure and aromatherapy groups compared with the control group in the post-test and post-three-week assessments. Sympathetic nervous activity was significantly lower in the fourth week in the aroma-acupressure group and in the second week in the aromatherapy group, whereas parasympathetic nervous activity increased from the second week to the fourth week in the aroma-acupressure group and in the fourth week in the aromatherapy group. Aroma-acupressure had a greater effect than aromatherapy on agitation in patients with dementia. However, agitation was improved in both of the groups, which allowed the patients with dementia to become more relaxed. Future studies should continue to assess the benefits of aroma-acupressure and aromatherapy for the treatment of agitation in dementia patients. ChiCTR-TRC-14004810; Date of registration: 2014/6/12.

    This study evaluated the effects of alpha/theta neurofeedback on Clinical Personality Accentuations in individuals with alcohol use disorder. Twenty-five males were investigated using a pre-test/post-test design with a waiting-list control group. Participants were randomly assigned either to an experimental group ( n = 13) receiving 12 sessions of neurofeedback twice a week as a treatment adjunct over a period of 6 weeks, or to a control group ( n = 12) receiving treatment as usual. The Inventory of Clinical Personality Accentuations and the NEO-Five-Factor Inventory were applied at pre- and post-test. The neurofeedback protocol focused on enhancement of the EEG alpha (8-12 Hz) and theta (4-7 Hz) and used a visual feedback paradigm. Analyses of covariance showed improvements in Avoidant Personality Accentuation within the experimental group. Our data suggest that 12 sessions of this neurofeedback intervention might be effective in reducing avoidant and stress-related personality traits in patients with alcohol use disorder.

    NASA s plans for Extravehicular Activity (EVA) portable life support systems for future exploration missions result in different design requirements than those which led to the combined fan / pump / separator in the current ISS Extravehicular Mobility Unit (EMU). To meet these new requirements, NASA contracted with Hamilton Sundstrand to provide two new prototype fans designed to meet anticipated future system requirements. Based on design trade studies, a high speed fan with mechanical bearing support of the rotating elements and a novel non-metallic barrier canned motor design was developed and implemented in the deliverable prototypes. The prototypes, which used two different bearing lubricants, have been extensively tested in both stand-alone and integrated system tests in NASA laboratories and proven to meet the anticipated performance requirements. Subsequently, they have been subjected to post test inspection and analysis in Hamilton Sundstrand laboratories to assess the effects of integrated operation and resultant exposure to vent loop contaminants. Results have confirmed expectations that one of the lubricants would be superior in this application and the prototype fans have been reassembled with new bearings with the superior lubricant. They have now been returned to the Johnson Space Center for further testing and maturation as part of NASA s PLSS 2.0 integrated test effort. This paper will discuss the test history of these units, resulting test data, the results of post test evaluation, and plans for further testing in the near future.

    Post-test calculations for verification purposes of the thermal hydraulic code RELAP5/MOD2 are of fundamental importance for the licensing procedure. The RELAP5/MOD2 code has a large international assessment base regarding western PWR. WWER-reactors are russian designed PWRs with some specific differences compared with the western PWR`s, especially the horizontal steam generators. For that reason some post-test calculations have to be performed to verify the RELAP5/MOD2 code for these WWER typical phenomena. The impact of the horizontal steam generators on the accident behaviour during transients or pipe ruptures on the secondary side is significant. The nodalization of the test facility PACTEL was chosen equally to WWER plant nodalization to verify the use of a coarse modelling of the steam generator secondary side for analyses of transient with decreasing water level in the SG secondary side. The calculational results showed a good compliance to the test results, demonstrating the correct use of a coarse nodalization. To sum up, the RELAP5/ MOD2 results met the test results appropriately thereby the RELAP5/ MOD2 code is validated for analyses of transients with decreasing water level in a horizontal steam generator secondary side.

    Several critical components removed from SIG (Selenide Isotope Generator) thermoelectric modules M-7, M-15C, M-15D, and M-18 were examined. These modules failed to show the predicted stability and conversion efficiency. Understanding the degradation and identifying means for preventing it necessitated detailed post-test examinations of key parts in the modules. Steel springs, which provided pressure for contacts at the hot and cold ends of P- or N-legs, relaxed more than expected. Beryllium oxide insulators had dark deposits that caused electrical shorts. The GdSe 1 49 N-leg exhibited cracking. The (Cu,Ag) 2 Se P-leg lost weight or sublimed excessively in module M-7 and more than expected in the other modules

    In this article, the test implementation of a school-oriented drug prevention program "Study without Drugs" is discussed. The aims of this study were to determine the results of the process evaluation and to determine whether the proposed school-oriented drug prevention program during a pilot project was effective for the participating pupils. Sixty second-grade pupils at a junior high school in Paramaribo, Suriname participated in the test implementation. They were divided into two classes. For the process evaluation the students completed a structured questionnaire focusing on content and teaching method after every lesson. Lessons were qualified with a score from 0-10. The process was also evaluated by the teachers through structured interviews. Attention was paid to reach, dose delivered, dose received, fidelity, connection, achieved effects/observed behaviors, areas for improvement, and lesson strengths. The effect evaluation was conducted by using the General Liniair Model (repeated measure). The research (-design) was a pre-experimental design with pre-and post-test. No class or sex differences were detected among the pupils with regard to the assessment of content, methodology, and qualification of the lessons. Post-testing showed that participating pupils obtained an increased knowledge of drugs, their drug-resisting skills were enhanced, and behavior determinants (attitude, subjective norm, self-efficacy, and intention) became more negative towards drugs. From the results of the test implementation can be cautiously concluded that the program "Study without Drugs" may yield positive results when applied in schools). Thus, this pilot program can be considered a step towards the development and implementation of an evidence-based school-oriented program for pupils in Suriname.

    Astronomy is increasingly moving towards working with large databases, from the state-of-the-art Sloan Digital Sky Survey Data Release 10, to the historical Digital Access to a Sky Century at Harvard. Non-astronomy fields as well tend to work with large datasets, be it in the form of warehouse inventory, health trends, or the stock market. However very few fields explicitly teach students the necessary skills to analyze such data. The authors studied a matched set of 37 participants working with 200-entry databases in astronomy using Google Spreadsheets, with limited information about a random set of quasars drawn from SDSS DR5. Here the authors present the quantitative results from an eight question pre-/post-test, with questions designed to span Bloom's taxonomy, on both the topics of the skills of using spreadsheets, and the content of quasars. Participants included both Astro 101 summer students and professionals including in-service K-12 teachers and science communicators. All groups showed statistically significant gains (as per Hake, 1998), with the greatest difference between women's gains of 0.196 and men's of 0.480.

    Full Text Available Iran’s education system is exam-based and to gain admission to universities at undergraduate, graduate, and postgraduate levels, candidates have to sit a competitive examination. For this reason, developing an EAP course which prepares the candidates for these examinations is of crucial importance. The present study attempted to develop an EAP course for the selected number of undergraduate students of Statistics at Alzahra University and Shahid Beheshti University in Tehran. The aim was to prepare these students for the English language section of the entrance examination for MS degree in Statistics and then to determine if there was any significant difference between students’ performance in their pre and post tests. Both quantitative and qualitative research methods were applied in this study and different instruments such as a questionnaire, semi-structured and structured interviews, and analysis of texts, were used to gather needs analysis data. The results indicated that the majority of participants preferred the presence of more ESP courses at universities. There was also a significant difference between pretest and posttest scores of the participants who took part in the EAP course.

    Objective: To investigate the accuracy of 320-slice row CT system for the detection of coronary artery disease (CAD) in high pre-test probability population without heart rate/rhythm control. Methods: Thirty patients with a high pre-test probability of CAD underwent 320-slice row CT without preceding heart rate/rhythm control. Invasive coronary angiography (ICA) served as the standard reference. Data sets were evaluated by 2 observers in consensus with respect to stenoses ≥50% decreased diameter. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and Youden index were analyzed; the impact of heart rate and calcification on image quality as well as diagnostic accuracy were also analyzed by Chi-square test. Results: Mean heart rate during scanning was 73.7±15.4 beats per min(bpm), and median(QR) of Agatston score of segment was 45.6 (181). On a per-segment analysis, overall sensitivity was 96.1% (74/77, 95% CI:89.03%-99.19%), specificity was 98.3% (337/343, 95% CI:96.23%-99.36%), PPV was 92.5% (74/80, 95% CI:84.39%-97.20%), NPV of 99.1% (337/340, 95% CI: 97.44%-99.82%) and the Youden index was 0.94. In both heart-rate subgroups (242 in heart rate < 70 bpm group, 169 in heart rate ≥70 bpm group), diagnostic accuracy for the assessment of coronary artery stenosis was similar (P<0.05). The accuracy and the quality score of the subgroup Agatston score ≥100 were lower than that of the subgroup Agatston score <100; however, the difference of results between 320-slice row CT and ICA was not significant (P<0.05). Conclusion: 320-detector row CT can reliably detect coronary artery stenoses in a high pre-test probability population without heart rate/rhythm control. (authors)

    Aim: To investigate the clinical impact of multidetector computed tomography (MDCT) in patients with a low versus a high pre-test likelihood of coronary artery disease (CAD). Materials and methods: A cohort of 120 patients with suspected CAD, scheduled for conventional coronary angiography, underwent MDCT. Using the American Heart Association (AHA)/American College of Cardiology (ACC) guidelines, the population was divided into two groups: patients with a low (group 1) and a high (group 2) likelihood of CAD. Results: Analysis of all segments showed a high feasibility (92%), and a patient based-model showed excellent sensitivity and negative predictive values (NPV; both 100%) and acceptable specificity and positive predictive values (PPV; 86 and 90%, respectively), with an accuracy of 94%. Using MDCT in patients with lower pre-test likelihoods of CAD, according to the ACC/AHA guidelines, the accuracy remained high (93%); conversely, in patient groups with a high prevalence of CAD, a non-significant reduction in accuracy (85%) occurred using MDCT. Particularly, MDCT can be used effectively to exclude a diagnosis of CAD because of its high sensitivity and NPV (100%), but shows a significant reduction in specificity (58%). This reduction was due to an increase in the false-positive:true-negative ratio because of the higher percentage of calcified plaque (a relative but non-significant increase in false positives), and the high prevalence of CAD (significant reduction in true negatives). No differences were found between MDCT and quantitative coronary angiography (QCA) concerning the number of vessels narrowed. Conclusion: Because of its excellent sensitivity and specificity in patients with a low pre-test likelihood of CAD, MDCT could be helpful in clinical decision-making in this population

The demonstration of in situ air stripping was the first in a series of demonstrations of innovative remediation technologies for the cleanup of sites contaminated with volatile organic contaminants. The in situ air stripping system consisted of two directionally drilled wells that delivered gases to and extract contamination from the subsurface. The demonstration was designed to remediate soils and sediments in the unsaturated and saturated zones as well as groundwater contaminated with volatile organic compounds. The demonstration successfully removed significant quantities of solvent from the subsurface. The field site and horizontal wells were subsequently used for an in situ bioremediation demonstration during which methane was added to the injected air. The field conditions documented herein represent the baseline status of the site for evaluating the in situ bioremediation as well as the post-test conditions for the in situ air stripping demonstration. Characterization activities focused on documenting the nature and distribution of contamination in the subsurface. The post-test characterization activities discussed herein include results from the analysis of sediment samples, three-dimensional images of the pretest and post-test data, contaminant inventories estimated from pretest and post-test models, a detailed lithologic cross sections of the site, results of aquifer testing, and measurements of geotechnical parameters of undisturbed core sediments.

    Recent studies show that a new strategy called differential-associative processing is effective for learning related concepts. However our knowledge about differential-associative processing is still limited. Therefore the goals of the present study are to assess the duration of knowledge that is acquired from using differential-associative processing, to determine whether the efficacy of differential-associative processing changes with the addition of a 10-minute pre-testing review, and to compare differential-associate processing to two conditions in which students select their own learning strategy. The results revealed that differential-associative processing was a better strategy for learning related concepts than were either of the two comparison conditions. They also revealed that a 10-minute pre-testing review had a positive additive influence on differential-associative processing. Finally, although the knowledge acquired from using differential-associative processing declined with an increase in delay between learning and testing, this decline was equivalent to the decline observed in both comparison conditions.

    This paper describes pretest analyses of a one-tenth scale model of the 'Sizewell-B' prestressed concrete containment building. The work was performed by ANATECH Research Corp. under contract with Sandia National Laboratories (SNL). Hydraulic testing of the model was conducted in the United Kingdom by the Central Electricity Generating Board (CEGB). In order to further their understanding of containment behavior, the USNRC, through an agreement with the United Kingdom Atomic Energy Authority (UKAEA), also participated in the test program with SNL serving as their technical agent. The analyses that were conducted included two global axisymmetric models with 'bonded' and 'unbonded' analytical treatment of meridional tendons, a 3D quarter model of the structure, an axisymmetric representation of the equipment hatch region, and local plane stress and r-θ models of a buttress. Results of these analyses are described and compared with the results of the test. A global hoop failure at midheight of the cylinder and a shear/bending type failure at the base of the cylinder wall were both found to have roughly equal probability of occurrence; however, the shear failure mode had higher uncertainty associated with it. Consequently, significant effort was dedicated to improving the modeling capability for concrete shear behavior. This work is also described briefly. (author)

    Full Text Available OBJECTIVES: Inhalation therapy is the main treatment for asthma and its adequate use has been a factor responsible for disease control; therefore, the aim of the study was to determine whether a digital media tool, which features portability on mobile phones, modifies the assimilation of the inhalation technique. METHODS: A total of 66 professionals working in the health care area with the pediatric population were selected. They were submitted to a pre-test on their knowledge of inhalation therapy. The professionals were randomized into two groups (A and B. Group A received a media application on their mobile phones showing the steps of inhalation therapy, while group B received the same information in written form only. A post-test was applied after 15 days. The results (pre- and post- were analyzed by two pediatric pulmonologists. RESULTS: Of the 66 professionals, 87.9% were females. Of a total possible score of ten, the mean score obtained in the pre-test was 5.3 ± 3, and in the second test, 7.5 ± 2 (p < 0.000. There were no significant differences when comparing the two groups (p = 0.726. The nurses had the lowest mean scores in the initial test (2.3 ± 2; however, they were the group that learned the most with the intervention, showing similar means to those of other groups in the second test (6.1 ± 3. CONCLUSION: There was significant improvement in knowledge about inhalation therapy in all professional categories using both methods, demonstrating that education, when available to professionals, positively modifies medical practice.

    Full Text Available Purpose: This study compared the effectiveness of group cognitive-behavioral therapy based on coping skills (CBT and methadone maintenance therapy (MMT in improvement of emotional regulation strategies and prevention of relapse. Method: The method of the present study was semi-experimental research design (pre-test-post-test with witness group. For sampling 45 substance abuse people who had referred to addiction treatment centers were selected and assigned to three groups of cognitive behavior therapy, methadone maintenance treatment and witness group randomly. The participants in all three groups completed the emotional intelligence questionnaire before and after the intervention. Data were analyzed by covariance method. Results: The results showed that cognitive-behavior therapy in comparison to methadone maintenance therapy and witness group led to significant improvement of emotional regulation in substance abusers, but there was no significant difference between the methadone maintenance treatment group and control group. Also, the rate of relapse in individuals who assigned to cognitive-behavior therapy group in comparison to methadone maintenance therapy and the witness group was significantly lower, but there was no significant difference between methadone therapy and witness. Conclusion: Cognitive-behavior therapy was an effective treatment that can change the cognitive and behavioral variables related to substance abuse, such as emotional regulation strategies. Thus, results suggested that drug abuse treatment programs must target these mediator variables.

    The work reported is part of a field experimental program to demonstrate and evaluate compressed air energy storage in a porous media aquifer reservoir near Pittsfield, Illinois. The reservoir is described. Numerical modeling of the reservoir was performed concurrently with site development. The numerical models were applied to predict the thermohydraulic performance of the porous media reservoir. This reservoir characterization and pre-test analysis made use of evaluation of bubble development, water coning, thermal development, and near-wellbore desaturation. The work was undertaken to define the time required to develop an air storage bubble of adequate size, to assess the specification of instrumentation and above-ground equipment, and to develop and evaluate operational strategies for air cycling. A parametric analysis was performed for the field test reservoir. (LEW)

    Service evaluations of medium secure hospital facilities for women are underrepresented in the extant literature. That positive changes in symptoms, personality traits and service need would be evident between admission and discharge among women in a medium security hospital service. A pre-test/post-test design was used, with comparisons made between admission and pre-discharge points on a variety of measures of psychiatric symptoms and personality traits. There were significant improvements in mood according to Beck Depression Inventory scores, mood and other symptoms of mental disorder and distress as measured by the Brief Psychiatric Rating Scale and the Modified Post Traumatic Stress Disorder Symptom Scale, personality traits recorded using the Millon Clinical Multiaxial Inventory III and service need as measured by the Camberwell Assessment of Need, Forensic Version. Significant positive change during treatment, in all clinical areas, is encouraging given poor outcomes for women reported in other research. Findings cannot, however, be unequivocally attributed to the treatments given. Further work is needed to improve early engagement and tailor treatment more specifically to the needs of a heterogeneous population. Copyright © 2014 John Wiley & Sons, Ltd.

    Objectives To compare how patients with chest pain would be investigated, based on the two guidelines available for UK cardiologists, on the management of patients with stable chest pain. The UK National Institute of Clinical Excellence (NICE) guideline which was published in 2010 and the European society of cardiology (ESC) guideline published in 2013. Both guidelines utilise pre-test probability risk scores, to guide the choice of investigation. Design We undertook a large retrospective study to investigate the outcomes of stress echocardiography. Setting A large tertiary centre in the UK in a contemporary clinical practice. Participants Two thirds of the patients in the cohort were referred from our rapid access chest pain clinics. Results We found that the NICE risk score overestimates risk by 20% compared to the ESC Risk score. We also found that based on the NICE guidelines, 44% of the patients presenting with chest pain, in this cohort, would have been investigated invasively, with diagnostic coronary angiography. Using the ESC guidelines, only 0.3% of the patients would be investigated invasively. Conclusion The large discrepancy between the two guidelines can be easily reduced if NICE adopted the ESC risk score. PMID:26673458

    Full Text Available The 4-H volunteer program is a new concept to the people of Iraq, for decades the country has been closed to western ideas. Iraqi culture and the Arabic customs have not embraced the volunteer concept and even more the concept of scientific animal production technologies designed to increase profitability for producers. In 2011 the USAID-Inma Agribusiness program teamed with the Iraq 4-H program to create youth and community entrepreneurship opportunities for widowed families. Iraq 4-H provided the youth members and adult volunteers and Inma provided the financial capital (livestock and the animal science training program for the volunteers. The purpose of this study was to measure the knowledge level gained through intensive animal science training for Iraqi 4-H volunteers. Researchers designed and implemented a pre and post test to measure the knowledge of fifteen volunteers who participated in the three day course. The pretest exposed a general lack of animal science knowledge of all volunteers; over 80% of the participants incorrectly answered the questions. However, the post-test indicated positive change in the participants understanding of animal science production principles.

  7. Conditional non-independence of radiographic image features and the derivation of post-test probabilities – A mammography BI-RADS example

    2012-01-01

    Bayes' theorem has proven to be one of the cornerstones in medical decision making. It allows for the derivation of post-test probabilities, which in case of a positive test result become positive predictive values. If several test results are observed successively Bayes' theorem may be used with assumed conditional independence of test results or with incorporated conditional dependencies. Herein it is examined whether radiographic image features should be considered conditionally independent diagnostic tests when post-test probabilities are to be derived. For this purpose the mammographic mass dataset from the UCI (University of California, Irvine) machine learning repository is analysed. It comprises the description of 961 (516 benign, 445 malignant) mammographic mass lesions according to the BI-RADS (Breast Imaging: Reporting and Data System) lexicon. Firstly, an exhaustive correlation matrix is presented for mammography BI-RADS features among benign and malignant lesions separately; correlation can be regarded as measure for conditional dependence. Secondly, it is shown that the derived positive predictive values for the conjunction of the two features “irregular shape” and “spiculated margin” differ significantly depending on whether conditional dependencies are incorporated into the decision process or not. It is concluded that radiographic image features should not generally be regarded as conditionally independent diagnostic tests.

    Knowledge of coping mechanisms is important for nursing and midwifery students to cope with stressful events during undergraduate education. To evaluate the impact of a psycho-educational intervention "Coping with Stressful Events" with first year undergraduate nursing and midwifery students. A quasi-experimental, one-group pre-post-test. One school of nursing/midwifery in one university in Ireland. A convenience sample of all first year undergraduate nursing and midwifery students (n=197). Of these 166 completed the pretest and 138 students completed the post test. Using the COPE Inventory questionnaire (Carver et al., 1989) data was collected pre and post-delivery of the psycho-educational intervention "Coping with Stressful Events" by two research assistants. Data were analysed using the IBM SPSS Statistics version 22 (NY, USA). Results demonstrated improved coping skills by students. There were statistically significant differences between pre and post intervention for some coping subscales. For example, the mean subscale scores were lower post-intervention for restraint and mental disengagement, and higher for use of emotional and instrumental social support indicating improved coping strategies. This intervention has the potential to influence undergraduate nursing and midwifery students coping skills during their first year of an undergraduate programme. Copyright © 2017 Elsevier Ltd.

    While television advertisements (ads) that communicate the serious harms of smoking are effective in prompting quitting-related thoughts and actions, little research has been conducted among smokers in low- to middle-income countries to guide public education efforts. 2399 smokers aged 18-34 years in 10 low- to middle-income countries (Bangladesh, China, Egypt, India, Indonesia, Mexico, Philippines, Russia, Turkey and Vietnam) viewed and individually rated the same five anti-smoking ads on a standard questionnaire and then engaged in a structured group discussion about each ad. Multivariate logistic regression analysis, with robust SEs to account for the same individual rating multiple ads, was performed to compare outcomes (message acceptance, perceived personalised effectiveness, feel uncomfortable, likelihood of discussing the ad) across ads and countries, adjusting for covariates. Ads by country interactions were examined to assess consistency of ratings across countries. Three ads with graphic imagery performed consistently highly across all countries. Two of these ads showed diseased human tissue or body parts, and a third used a disgust-provoking metaphor to demonstrate tar accumulation in smokers' lungs. A personal testimonial ad performed more variably, as many smokers did not appreciate that the featured woman's lung cancer was due to smoking or that her altered physical appearance was due to chemotherapy. An ad using a visual metaphor for lung disease was also more variable, mostly due to lack of understanding of the term 'emphysema'. Television ads that graphically communicate the serious harms of tobacco use are likely to be effective with smokers in low- to middle-income countries and can be readily translated and adapted for local use. Ads with complex medical terms or metaphors, or those that feature personal testimonials, are more variable and at least require more careful pre-testing and adaptation to maximise their potential.

    To examine the effects of individual video-feedback on the generic communication skills, clinical competence (i.e. adherence to practice guidelines) and motivational interviewing skills of experienced practice nurses working in primary care. Continuing professional education may be necessary to refresh and reflect on the communication and motivational interviewing skills of experienced primary care practice nurses. A video-feedback method was designed to improve these skills. Pre-test/posttest control group design. Seventeen Dutch practice nurses and 325 patients participated between June 2010-June 2011. Nurse-patient consultations were videotaped at two moments (T0 and T1), with an interval of 3-6 months. The videotaped consultations were rated using two protocols: the Maastrichtse Anamnese en Advies Scorelijst met globale items (MAAS-global) and the Behaviour Change Counselling Index. Before the recordings, nurses were allocated to a control or video-feedback group. Nurses allocated to the video-feedback group received video-feedback between T0 and T1. Data were analysed using multilevel linear or logistic regression. Nurses who received video-feedback appeared to pay significantly more attention to patients' request for help, their physical examination and gave significantly more understandable information. With respect to motivational interviewing, nurses who received video-feedback appeared to pay more attention to 'agenda setting and permission seeking' during their consultations. Video-feedback is a potentially effective method to improve practice nurses' generic communication skills. Although a single video-feedback session does not seem sufficient to increase all motivational interviewing skills, significant improvement in some specific skills was found. Nurses' clinical competences were not altered after feedback due to already high standards. © 2014 John Wiley & Sons Ltd.

    Full Text Available The aim of this study was to ascertain the effects of a holistic short-term group intervention in the treatment of Irritable Bowel Syndrome (/BS with comorbid depression and anxiety. The sample consisted of 24 South African women who had been diagnosed with severe IBS. Furthermore, each participant had to have associated moderate to severe depression and anxiety. The group design was a pre-test, post-test control group design where the experimental group (n = 12 received group intervention and the members of the control group (n = 12 received no intervention until after completion of the research. All the participants completed the Functional Bowel Disorder Severity Index and the Depression and Anxiety subscales of the Personality Assessment Inventory before commencement of group therapy for Group 1 and one month after completion of this intervention. The effect of the intervention was determined by utilising comparative statistics. The findings indicate that holistic short-term group therapy results in significant improvement in terms of depreSSion and anxiety scores, but that IBS symptom severity remains unchanged. It is recommended that further research be conducted to ascertain whether holistic group therapy of a longer duration has a greater impact on the IBS symptom severity.

    Full Text Available Abstract Background One potential concern with using mailed surveys containing trauma-related content is the possibility of re-traumatizing survivors without a trained mental health professional present. Prior research provides insufficient guidance regarding the prevalence and magnitude of this risk because the psychological harms of trauma-related surveys have typically been estimated using single post-test observations. Post-test observations cannot quantify magnitude of change in participants’ emotional states and may over or under estimate associations between participants’ characteristics (risk factors and post-survey upset. Methods We conducted two pre- and post-test studies in samples of former applicants for posttraumatic stress disorder disability benefits: 191 males who served during Gulf War I plus 639 male and 921 female Veterans who served sometime between 1955 and 1998. We used two 9-point items from the Self-Assessment Manikins to measure participants’ valence (sadness/happiness and arousal (tenseness/calmness before and after they completed mailed surveys asking about trauma-related symptoms or experiences. We examined the following potential predictors for post-survey sadness and tenseness: screening positive for posttraumatic stress disorder, having a serious mental illness, and history of military sexual assault or combat. Results After the survey, across the groups, 29.3–41.8% were sadder, 45.3–52.2% had no change in valence, and 12.9–22.5% were happier; 31.7–40.2% were tenser, 40.6–48.2% had no change in arousal, and 17.3–24.0% were calmer. The mean increase in sadness or tenseness post-survey was less than one point in all groups (SD’s < 1.7. Cohen’s d ranged from 0.07 to 0.30. Most hypothesized predictors were associated with greater baseline sadness or tenseness, but not necessarily with larger post-survey changes. Women with a history of military sexual assault had the largest net post

We conducted two pre- and post-test studies in samples of former applicants for posttraumatic stress disorder disability benefits: 191 males who served during Gulf War I plus 639 male and 921 female Veterans who served sometime between 1955 and 1998. We used two 9-point items from the Self-Assessment Manikins to measure participants' valence (sadness/happiness) and arousal (tenseness/calmness) before and after they completed mailed surveys asking about trauma-related symptoms or experiences. We examined the following potential predictors for post-survey sadness and tenseness: screening positive for posttraumatic stress disorder, having a serious mental illness, and history of military sexual assault or combat. After the survey, across the groups, 29.3-41.8% were sadder, 45.3-52.2% had no change in valence, and 12.9-22.5% were happier; 31.7-40.2% were tenser, 40.6-48.2% had no change in arousal, and 17.3-24.0% were calmer. The mean increase in sadness or tenseness post-survey was less than one point in all groups (SD's survey changes. Women with a history of military sexual assault had the largest net post-survey changes in sadness (mean = 0.7, SD = 1.4) and tenseness (mean = 0.6, SD = 1.6). While a substantial minority of Veterans reported more sadness or tenseness post-survey, the net change in affect was small. Most hypothesized risk

    Full Text Available Abstract Background Nested case–control studies become increasingly popular as they can be very efficient for quantifying the diagnostic accuracy of costly or invasive tests or (biomarkers. However, they do not allow for direct estimation of the test’s predictive values or post-test probabilities, let alone for their confidence intervals (CIs. Correct estimates of the predictive values itself can easily be obtained using a simple correction by the (inverse sampling fractions of the cases and controls. But using this correction to estimate the corresponding standard error (SE, falsely increases the number of patients that are actually studied, yielding too small CIs. We compared different approaches for estimating the SE and thus CI of predictive values or post-test probabilities of diagnostic test results in a nested case–control study. Methods We created datasets based on a large, previously published diagnostic study on 2 different tests (D-dimer test and calf difference test with a nested case–control design. We compared six different approaches; the approaches were: 1. the standard formula for the SE of a proportion, 2. adaptation of the standard formula with the sampling fraction, 3. A bootstrap procedure, 4. A approach, which uses the sensitivity, the specificity and the prevalence, 5. Weighted logistic regression, and 6. Approach 4 on the log odds scale. The approaches were compared with respect to coverage of the CI and CI-width. Results The bootstrap procedure (approach 3 showed good coverage and relatively small CI widths. Approaches 4 and 6 showed some undercoverage, particularly for the D-dimer test with frequent positive results (positive results around 70%. Approaches 1, 2 and 5 showed clear overcoverage at low prevalences of 0.05 and 0.1 in the cohorts for all case–control ratios. Conclusion The results from our study suggest that a bootstrap procedure is necessary to assess the confidence interval for the predictive

    At the University for Applied Sciences Zittau/Goerlitz (FH) calculations for the verification of the ATHLET-code for reactors of type VVER are carried out since 1991, sponsored by the German Ministry for Education, Science and Technology (BMBF). The special features of these reactors in comparison to reactors of western countries are characterized by the duct route of reactor coolant pipes and the horizontal steam generators. Because of these special features, a check of validity of the ATHLET-models is necessary. For further verification of the ATHLET-code the post test calculation of the experiment SBL-22 (Small break loss-of-coolant test) realized at the finnish facility PACTEL was carried out. The experiment served for the examination of the natural circulation behaviour of the loop over a continuous range of primary side water inventory. 5 refs.

    This paper presents the pre- and post-test results of the outcomes of a workshop designed to increase learning disability and mental health nurses' knowledge and skill to undertake interventions for service users at risk of, or with a diagnosis of, type 2 diabetes. Health literacy is also discussed as a way of explaining why such nurses may lack expertise in physical health care. Findings from the workshop show that learning disability and mental health nurses have the motivation to increase their health literacy (skills and knowledge) in diabetes care. The potential of such workshops, and how organisations looking forward to the future can build health literacy, is discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

    In the US, an unacceptably high percentage of pregnant women do not undergo prenatal HIV testing. Previous studies have found increased uptake of prenatal HIV testing with abbreviated pre-test counseling, however little is known about patient decision making, testing satisfaction and knowledge in this setting. A randomized-controlled, non-inferiority trial was conducted from October 2006 through February 2008 at San Francisco General Hospital (SFGH), the public teaching hospital of the City and County of San Francisco. A total of 278 English- and Spanish-speaking pregnant women were randomized to receive either abbreviated or standard nurse-performed HIV test counseling at the initial prenatal visit. Patient decision making experience was compared between abbreviated versus standard HIV counseling strategies among a sample of low-income, urban, ethnically diverse prenatal patients. The primary outcome was the decisional conflict score (DCS) using O'Connor low-literacy scale and secondary outcomes included satisfaction with test decision, basic HIV knowledge and HIV testing uptake. We conducted an intention-to-treat analysis of 278 women--134 (48.2%) in the abbreviated arm (AA) and 144 (51.8%) in the standard arm (SA). There was no significant difference in the proportion of women with low decisional conflict (71.6% in AA vs. 76.4% in SA, p = .37), and the observed mean difference between the groups of 3.88 (95% CI: -0.65, 8.41) did not exceed the non-inferiority margin. HIV testing uptake was very high (97. 8%) and did not differ significantly between the 2 groups (99.3% in AA vs. 96.5% in SA, p = .12). Likewise, there was no difference in satisfaction with testing decision (97.8% in AA vs. 99.3% in SA, p = .36). However, women in AA had significantly lower mean HIV knowledge scores (78.4%) compared to women in SA (83.7%, pprocess, while associated with slightly lower knowledge, does not compromise patient decision making or satisfaction regarding HIV testing

    The importance of using technologies such as e-learning in different disciplines is discussed in the literature. Researchers have measured the effectiveness of e-learning in a number of fields.Considering the lack of research on the effectiveness of online learning in dental education particularly in Iran, the advantages of these learning methods and the positive university atmosphere regarding the use of online learning. This study, therefore, aims to compare the effects of two methods of teaching (virtual versus traditional) on student learning. This post-test only design study approached 40, fifth year dental students of Shiraz University of Medical Sciences. From this group, 35 students agreed to participate. These students were randomly allocated into two groups, experimental (virtual learning) and comparison (traditional learning). To ensure similarity between groups, we compared GPAs of all participants by the Mann-Whitney U test (P > 0.05). The experimental group received a virtual learning environment courseware package specifically designed for this study, whereas the control group received the same module structured in a traditional lecture form. The virtual learning environment consisted of online and offline materials. Two identical valid, reliable post-tests that consisted of 40 multiple choice questions (MCQs) and 4 essay questions were administered immediately (15 min) after the last session and two months later to assess for knowledge retention. Data were analyzed by SPSS version 20. A comparison of the mean knowledge score of both groups showed that virtual learning was more effective than traditional learning (effect size = 0.69). The newly designed virtual learning package is feasible and will result in more effective learning in comparison with lecture-based training. However further studies are needed to generalize the findings of this study.

    Maintaining the health and well-being of family carers of people with dementia is vital, given their potential for experiencing burden associated with the role. The study aimed to help dementia carers develop self-efficacy, be less hassled by the caring role and improve their health and well-being with goal-directed behaviour, by participating in an eight module carer coaching program. The study used mixed methods in a pre/post-test/follow-up design over 24 months, with assignment of consented dementia carers to either individualised (n = 16) or group coaching (n = 32), or usual carer support services (n = 43), depending on preference. Care-giving self-efficacy and hassles, carer health, well-being and goal-directed behaviours were assessed over time. Analysis of Variance (ANOVA) was used to compare changes over time and the effects of coaching on carer self-efficacy, hassles and health, using the Univariate General Linear Model (GLM). All carers were hassled by many aspects of caring at baseline. Participants receiving coaching reported non-significant improvements in most areas of self-efficacy for caring, hassles associated with caring and self-reported health at post-test and follow-up, than did carers receiving usual carer support. Group coaching had greater success in helping carers to achieve their goals and to seek help from informal and formal support networks and services. The study outcomes were generally positive, but need to be interpreted cautiously, given some methodological limitations. It has been shown, however, that health staff can assist dementia carers to develop self-efficacy in better managing their family member's limitations and behaviour, seek help from others and attend to their health. Teaching carers to use goal-directed behaviour may help them achieve these outcomes.

    Emergency Triage Assessment and Treatment (ETAT) was developed by the WHO to teach paediatric assessment, triage and initial management to healthcare workers (HCWs) in resource-limited hospital-based settings. This study sought to evaluate the extension of ETAT training from a regional hospital to paediatric HCWs at local primary care health centres (PHCs) in Guatemala. Prior to providing a 16 h ETAT training module, immediately after, and at 3, 6 and 12 months, we used written pre-tests and post-tests and five-point Likert surveys to evaluate, respectively, clinical knowledge and provider confidence in providing acute care paediatrics; hands-on clinical skills were tested at 3, 6 and 12 months. Fifty-two HCWs (14 general physicians, 38 nurses) from four regional PHCs participated; 65%, 60% and 46% completed 3-month, 6-month and 12-month follow-ups, respectively. Test scores show significant acquisition of clinical knowledge initially, which was retained over time when tested at 3, 6 and 12 months (46 vs 70, pscale-up of ETAT.

    The efficacy of traditional follow-up care is being challenged, as cancer survivors' supportive and psychological needs are often neither identified, nor addressed. This study's aim was to develop a holistic surgical follow-up clinic for oral and oropharyngeal cancer patients were participants completed a disease-specific health-related quality of life tool (UWQOLv4) and item prompt list (Patient Concern Inventory) on a touchscreen computer. Information generated was used to focus the consultation on patient's identified needs and concerns. By means of a prospective non-randomised, pre-test post-test design, this follow-up clinic was evaluated using the patient enablement instrument (PEI) and patient content checklist (PCC). Feasibility was explored from the patient perspective (satisfaction survey) and clinician perspective (qualitative interview). Forty-four consecutive patients were recruited. Findings demonstrating five of the eight topics (overall QOL, emotions, head and neck symptoms, side-effects of treatment, chronic non-specific) on PCC were discussed more frequently, but changes were not statistically significant. The PEI highlighted a trend towards perceived improvement in four of the six items. Using touchscreen computers to aid communication during routine follow-up was reported as both feasible and beneficial by patients and clinicians. Providing a patient-focused follow-up consultation can facilitate the identification of unmet needs, permitting timely and appropriate intervention being initiated. © 2018 John Wiley & Sons Ltd.

The aim of present research was study the effects of motivational interviewing on adherence to in obese patients undergoing sleeve gastrectomy surgery. Methods: The design of present semi- experimental study was pre-test, post-test with control group. The statistical population included all obese patients (BMI≥35 that undergone laparoscopic sleeve gastrectomy surgery in Shiraz Ghadir Mother & Child Subspecialty Hospital, during the winter of 1394 and the spring of 1395. 30 of them were selected by using available sampling method and they randomly were asssigned to experimental (n=15 and control groups (n=15. The post bariatic surgery self-management behaviors questionnaire was used to collect data in two steps (pre-test and post-test. Motivational interviewing was implemented for the experimental group in four weeks (each week a 1/5 hour session. Data were analysed by using multivariate covariance analysis (MANCOVA. Results: MANCOVA results show that motivational interviewing led to a statistically significant difference between pre-test and post-test BSSQ total scores (P0/07. Conclusion: According to this study results, implementation of motivational interviewing is effective and appropriate in order to enhance adherence and self-management behaviors, achieve favorable weight loss & reduce postoperative complications, in obese patients undergoing sleeve gastrectomy surgery, but it appears that longer interventions are necessary to increase the rate of physical activity.

    A 20kW carbonate fuel cell stack was operated with coal gas for the first time in the world. The stack was tested for a total of 4,000 hours, of which 3,900 hours of testing was conducted at the Louisiana Gasification Technology Incorporated, Plaquemine, Louisiana outdoor site. The operation was on either natural gas or coal gas and switched several times without any effects, demonstrating duel fuel capabilities. This test was conducted with 9142 kJ/m{sup 3} (245 Btu/cft) coal gas provided by a slipstream from Destec`s entrained flow, slagging, slurry-fed gasifier equipped with a cold gas cleanup subsystem. The stack generated up to 21 kW with this coal gas. Following completion of this test, the stack was brought to Energy Research Corporation (ERC) and a detailed post-test analysis was conducted to identify any effects of coal gas on cell components. This investigation has shown that the direct fuel cell (DFC) can be operated with properly cleaned and humidified coal-as, providing stable performance. The basic C direct fuel cell component materials are stable and display normal stability in presence of the coal gas. No effects of the coal-borne contaminants are apparent. Further cell testing at ERC 1 17, confirmed these findings.

    A four-layer solid oxide fuel cell stack with planar anode-supported cells was operated galvanostatically at 700 °C and 0.5Acm-2 for nearly 35,000 h. One of the four planes started to degrade more rapidly after ∼28,000 h and finally more progressively after ∼33,000 h. The stack was then shut down and a post-test analysis was carefully performed. The cell was characterized with respect to cathodic impurities and clarification of the reason(s) for failure. Wet chemical analysis revealed very low chromium incorporation into the cathode. However, SEM and TEM observations on polished and fractured surfaces showed catastrophic failure in the degraded layer. The cathode-barrier-electrolyte cell layer system delaminated from the entire cell over large areas. The source of delamination was the formation of a porous, sponge-like secondary phase consisting of zirconia, yttria and manganese (oxide). Large secondary phase islands grew from the electrolyte-anode interface towards the anode and cracked the bonding between both layers. The manganese originated from the contact or protection layers used on the air side. This stack result shows that volatile species - in this case manganese - should be avoided, especially when long-term applications are envisaged.

    High-temperature heat pipes are being evaluated for use in energy conversion applications such as fuel cells, gas turbine re-combustors, Stirling cycle heat sources; and with the resurgence of space nuclear power both as reactor heat removal elements and as radiator elements. Long operating life and reliable performance are critical requirements for these applications. Accordingly, long-term materials compatibility is being evaluated through the use of high-temperature life test heat pipes. Thermacore, Inc., has carried out a sodium heat pipe 10-year life test to establish long-term operating reliability. Sodium heat pipes have demonstrated favorable materials compatibility and heat transport characteristics at high operating temperatures in air over long time periods. A representative one-tenth segment Stirling Space Power Converter heat pipe with an Inconel 718 envelope and a stainless steel screen wick has operated for over 87,000 hr (10 yr) at nearly 700 C. These life test results have demonstrated the potential for high-temperature heat pipes to serve as reliable energy conversion system components for power applications that require long operating lifetime with high reliability. Detailed design specifications, operating history, and post-test analysis of the heat pipe and sodium working fluid are described.

    The calculations were performed with SSYST-3 code system. The experiments have been carried out with shortened REBEKA simulators. The main goal was to verify whether the model for describing the Zircaloy cladding deformation and rupture at high temperatures (NORA2 model) is able to predict the Argentine cladding material behaviour under such conditions. A good agreement between experimental results and model predictions was found in the range of temperatures from 700 to 850 0 C (in α phase and first half of α+β transition phase). There were some discrepances at higher temperatures, probably due to the strong influence of heating rate on material properties. According to the results of these post-test calculations, it can be concluded that NORA2 model is able to well describe the Argentine Zircaloy cladding deformation and rupture under LOCA conditions, because there was a good agreement in the range of burst (ballooning) temperatures which are expected in this type of accident.

    To foster nursing professionals, nursing education requires the integration of knowledge and practice. Nursing students in their senior year experience considerable stress in performing the core nursing skills because, typically, they have limited opportunities to practice these skills in their clinical practicum. Therefore, nurse educators should revise the nursing curricula to focus on core nursing skills. To identify the effect of an intensive clinical skills course for senior nursing students on their self-confidence and clinical competence. A quasi-experimental post-test study. A university in South Korea during the 2015-2016 academic year. A convenience sample of 162 senior nursing students. The experimental group (n=79) underwent the intensive clinical skills course, whereas the control group (n=83) did not. During the course, students repeatedly practiced the 20 items that make up the core basic nursing skills using clinical scenarios. Participants' self-confidence in the core clinical nursing skills was measured using a 10-point scale, while their clinical competence with these skills was measured using the core clinical nursing skills checklist. Independent t-test and chi-square tests were used to analyze the data. The mean scores in self-confidence and clinical competence were higher in the experimental group than in the control group. This intensive clinical skills courses had a positive effect on senior nursing students' self-confidence and clinical competence for the core clinical nursing skills. This study emphasizes the importance of reeducation using a clinical skills course during the transition from student to nursing professional. Copyright © 2017. Published by Elsevier Ltd.

    Preparing nursing students to perform competently in complex emergency situations, such as during rapid patient deterioration, is challenging. Students' active engagement in such scenarios cannot be ensured, due to the unexpected nature of such infrequent events. Many students may consequently not experience and integrate the management of patient deterioration into their knowledge and practical competency by the end of their studies, making them unprepared to manage such situations as practicing nurses. This study investigated the effectiveness of virtual simulation in improving performance during rapid patient deterioration. To investigate the effectiveness of virtual simulation in improving student nurses' knowledge and performance during rapid patient deterioration. A pre- and post-test design was used. Nursing students at a university in Malta were invited to participate in a virtual simulation program named FIRST 2 ACTWeb™, using their own computer devices. A total of 166 (response rate=50%) second and third year diploma and degree nursing students participated in the study. The simulation included three scenarios (Cardiac-Shock-Respiratory) portraying deteriorating patients. Performance feedback was provided at the end of each scenario. Students completed pre- and post-scenario knowledge tests and performance during each scenario was recorded automatically on a database. Findings showed a significant improvement in the students' post-scenario knowledge (z=-6.506, psimulation as an effective learning tool for pre-registration nursing students in different programs. Simulation improves both knowledge about and performance during patient deterioration. Virtual simulation of rare events should be a key component of undergraduate nurse education, to prepare students to manage complex situations as practicing nurses. Copyright © 2018 Elsevier Ltd.

    This paper mainly deals with the improvement in the post test accident analysis results prediction for the test no. 2, 'Total loss of feed water with failure of HPIS pumps and operator actions on primary and secondary circuit depressurization', carried-out on PSB integral test facility in May 2005. This is one the most complicated test conducted in PSB test facility. The prime objective of this test is to provide support for the verification of the accident management strategies for NPPs and also to verify the correctness of some safety systems operating only during accident. The objective of this analysis is to assess the capability to reproduce the phenomena occurring during the selected tests and to quantify the accuracy of the code calculation qualitatively and quantitatively for the best estimate code Relap5/mod3.3 by systematically applying all the procedures lead by Uncertainty Methodology based on Accuracy Extrapolation (UMAE), developed at University of Pisa. In order to achieve these objectives test facility nodalisation qualification for both 'steady state level' and 'on transient level' are demonstrated. For the 'steady state level' qualification compliance to acceptance criteria established in UMAE has been checked for geometrical details and thermal hydraulic parameters. The following steps have been performed for evaluation of qualitative qualification of 'on transient level': visual comparisons between experimental and calculated relevant parameters time trends; list of comparison between experimental and code calculation resulting time sequence of significant events; identification/verification of CSNI phenomena validation matrix; use of the Phenomenological Windows (PhW), identification of Key Phenomena and Relevant Thermal-hydraulic Aspects (RTA). A successful application of the qualitative process constitutes a prerequisite to the application of the quantitative analysis.

    To evaluate the impact of a structured learning programme as a component of the clinical practicum in final year bachelor of nursing course on the student's report of their anxiety and self-efficacy pre-post programme participation. Student anxiety and low levels of self-efficacy are known to affect the quality of clinical learning. A three-day structured learning programme at the commencement of an acute care clinical placement was designed to reduce student anxiety and enhance self-efficacy. A pre-post test design. The hospital anxiety and depression scale (The HAD) and the general self-efficacy scale (GSES-12) were administered prior to the commencement of the structured learning programme (time one) and at the end of the programme (time two). One hundred and twenty final year students undertaking an acute care clinical placement participated in the programme in three cohorts and completed the questionnaires at time one and 118 at time two. Students levels of anxiety >8 with The HAD pre-post programme 53 vs. 30% (p learning programme resulted in a statistically significant reduction in student anxiety and increase in self-efficacy across the three cohort groups. This effect can be achieved with the development of a relatively low cost/low technology structured learning programme that is part of an acute care clinical placement. Nurse educators should not assume that students are less anxious about their acute care clinical placements as the semester proceeds. There is a typical correlation between increased anxiety and decreased self-efficacy which is likely to impact on student learning in the clinical setting. Significant results can be achieved with a relatively low cost and a low technology enabling intervention. © 2011 Blackwell Publishing Ltd.

    The aim of this study was to determine whether attendance at an occupational therapy-led day treatment centre for mental health care users affects the use of inpatient services in South Africa. A retrospective pre-test/post-test quasi-experimental study design was used to compare admissions and days spent in hospital during the 24 months before and after attendance at the centre, using the hospital's electronic records. Total population sampling yielded data for 44 mental health care users who made first contact with the service between July 2009 and June 2010. Data were compared using the Kruskal-Wallis test, Wilcoxon Signed Ranks test and Mann-Whitney U test. There was a significant decrease in the number of admissions (z = -4.093, p = 0.00) and the number of days spent in hospital (z = -4.730, p = 0.00). Participants were admitted to psychiatric care 33 times less in the 24 months' post-intervention, indicating a medium effect (r = 0.436). They also spend 2569 days less in hospital, indicating a large effect (r = 0.504). The findings suggest that an occupational therapy-led day treatment centre could be effective in reducing the use of inpatient mental health services in South Africa. Implications for Rehabilitation Attendance at an occupational therapy-led community day treatment centre decreases the number of admissions and number of days spent in hospital and is therefore beneficial to mental health care users and service providers. The study indicates that the successful implementation of a community day treatment centre for mental health care users on the grounds of a tertiary hospital by utilising existing resources is possible.

This paper briefly introduces the basic design features of the Korea Atomic Energy Research Institute-ITL and presents the results of pre-test analysis for a postulated cold leg SBLOCA and DVI line break. Based on the same control logics and accident scenarios, the similarity between the Korea Atomic Energy Research Institute-ITL and the prototype plant, APR1400, is evaluated by using the MARS code, which is a multi-dimensional best-estimate thermal hydraulic code being developed by Korea Atomic Energy Research Institute. It is found that the Korea Atomic Energy Research Institute-ITL and APR 1400 have similar thermal hydraulic responses against the analyzed SBLOCA and DVI Line break scenario. It is also verified that the volume scaling law, applied to the design of the Korea Atomic Energy Research Institute-ITL, gives a reasonable results to keep a similarity with APR1400. 11 refs., 19 figs., 3 tabs.

    Nonpharmacological interventions, including combinations of music, education, coping skills, and relaxation techniques, have been found to have a positive effect on patients' perceived anxiety in many settings. However, few research studies have assessed and compared the effectiveness of music and relaxation interventions in reducing the anxiety levels of orthopaedic and oncology patients. We conducted a prospective, randomized, controlled study to examine the effectiveness of music and relaxation interventions on perceived anxiety during initial hospitalization for patients receiving orthopaedic or cancer care treatment at a Midwestern teaching hospital. This was a pre-test/post-test study design utilizing the State-Trait Anxiety Inventory. One hundred twelve patients were randomized into 3 study groups. Thirty-eight subjects (34%) were randomized in the music-focused relaxation group, 35 subjects (31%) in the music and video group, and 39 (35%) subjects in the control group. Fifty-seven (51%) were orthopaedic patients and 55 (49%) were oncology patients. Comparison of the 3 study groups showed no statistically significant differences with regard to patients' demographics. Although reduced anxiety levels were reported for all 3 groups postintervention, the differences were not statistically significant (p > .05). Also, there was no significant difference found between the perceived anxiety levels of patients admitted to the orthopaedic and oncology care units (p > .05). Finally, the results of the intragroup comparisons (regardless of the group assignment) showed a significant decrease in anxiety levels reported by all patients postintervention (p Music and relaxation interventions could be an additional tool in assisting patients to become less anxious during their hospital stay. Music focused relaxation and music and video are both valuable and cost-effective strategies that can assist the orthopaedic and oncology patient population. Identifying opportunities to

  19. Verification of the ATHLET computer code based on post-test analyses of BETHSY experiments (BETHSY 4.1a TC and BETHSY 3.4a). Final report

    1994-10-01

    To validate the fluid dynamic computer code ATHLET a post-test calculation of experiment BETHSY 4.1aTC was performed. The test objective was the investigation of natural circulation at constant core power (5% nominal power) at different mass inventories in the primary circuit and the steam generators. BETHSY 4.1aTC consists of 2 phases with different liquid levels in the steam generators: Nominal liquid level (H=13.5 m) in phase 1 and reduced liquid level (H=1 m) in phase 2. The results of the post-test calculations of both phases showed excellent agreement with the experimental data (pressure differences in the primary circuit, loop flow rates) before the beginning of vaporization in the U-tubes. Subsequently the calculated results concerning the difference of the average void fraction in the ascending and descending leg of the U-tubes disagreed from the measured data in phase 1 leading to discrepancies between calculated and measured data with respect to the loop flow rates and other physical quantities. In phase 2 of the experiment market cyclic filling and voiding processes in the U-tubes are detected, which are not simulated qualitatively in the calculation. These processes possibly lead to an increase in the global heat transfer between primary and secondary circuit in the experiment which is not predicted in the calculation. As a consequence dry out in the core occurs in the calculation, however not in the experiment. The code version ATHLET Mod 1.1, Cycle A has an increased robustness compared to the predecessor version ATHLET Mod 1.0, Cycle E. This could be demonstrated in a post-test calculation of the BETHSY 3.4a, which was already analysed in project 1500887 using the version ATHLET Mod 1.0, Cycle E. Whereas significant numerical problems (e.g. code breakdowns) occured in the latter calculation, the corresponding simulation using the new version performed smoothly and showed identical results with a reduced computer run time.

    Attention-Deficit-Hyperactivity-Disorder (ADHD) is, with a prevalence of 5 %, a highly common childhood disorder, and has severe impact on the lives of youngsters and their families. Medication is often the treatment of choice, as it currently is most effective. However, medication has only short-term effects, treatment adherence is often low and most importantly; medication has serious side effects. Therefore, there is a need for other interventions for youngsters with ADHD. Mindfulness training is emerging as a potentially effective training for children and adolescents with ADHD. The aim of this study is to compare the (cost) effectiveness of mindfulness training to the (cost) effectiveness of methylphenidate in children with ADHD on measures of attention and hyperactivity/impulsivity. A multicenter randomized controlled trial with 2 follow-up measurements will be used to measure the effects of mindfulness training versus the effects of methylphenidate. Participants will be youngsters (aged 9 to 18) of both sexes diagnosed with ADHD, referred to urban and rural mental healthcare centers. We aim to include 120 families. The mindfulness training, using the MYmind protocol, will be conducted in small groups, and consists of 8 weekly 1.5-h sessions. Youngsters learn to focus and enhance their attention, awareness, and self-control by doing mindfulness exercises. Parents will follow a parallel mindful parenting training in which they learn to be fully present in the here and now with their child in a non-judgmental way, to take care of themselves, and to respond rather than react to difficult behavior of their child. Short-acting methylphenidate will be administered individually and monitored by a child psychiatrist. Assessments will take place at pre-test, post-test, and at follow-up 1 and 2 (respectively 4 and 10 months after the start of treatment). Informants are parents, children, teachers, and researchers. This study will inform mental health care

    The study aims to evaluate the effects of a communication skills training programme on community aged care staff's knowledge of communication support in dementia and on staff's care experience. Dementia can lead to impairments in communication. Therefore, quality community-based dementia care requires that staff be skilled communicators, equipped to facilitate interactions with people with dementia. The current investigation evaluated the effectiveness of the MESSAGE Communication Strategies in Dementia for Care Staff training programme with respect to knowledge of communication support and the staff/caregiver experience. A multi-centre controlled pretest/post-test design with randomised cohort allocation was used. Outcome measures were completed at baseline, immediately after training (training group only), and at three-month follow-up. Thirty-eight care staff working in community aged care participated and completed all outcome measures (training = 22; control = 16).Training and control groups completed the following outcome measures: knowledge of communication support strategies, self-efficacy, preparedness to provide care, strain in nursing care and attitude to dementia care. Staff in the training group provided written feedback on the training. A significant improvement in knowledge scores from baseline was found for the training group both immediately after training and at three-month follow-up. There was also a significant training effect for self-efficacy and preparedness to provide care. No significant difference was found for the control group for any measure. No significant training effects were found for measures of strain or attitudes to dementia care. Feedback from staff suggests that the training was well received. The MESSAGE training was positively received by staff and had a significant effect on care staff knowledge, and confidence to provide care for people with dementia. The easily accessible multimedia training programme is well received by

    Full Text Available Abstract Background Most valid methods to measure treatment adherence require time and resources, and they are not easily applied in highly demanding Primary Health Care Clinics (PHCC. The objective of this study was to determine sensitivity, specificity, predictive values, likelihood ratios, and post-test probabilities of two novel questionnaires as proxy measurements of treatment adherence in Type-2 diabetic patients. Methods Two questionnaires were developed by a group of experts to identify the patient's medical prescription knowledge (knowledge and their attitudes toward treatment adherence (attitudes as proxy measurements of adherence. The questionnaires were completed by patients receiving care in PHCC pertaining to the Mexican Institute of Social Security in Aguascalientes (Mexico. Pill count was used as gold standard. Participants were selected randomly, and their oral hypoglycemic prescriptions were studied. The main outcome measures for each questionnaire were sensitivity, specificity, predictive values, likelihood ratios, and post-test probabilities, all as an independent questionnaire test and in a serial analysis. Results Adherence prevalence was 27.0% using pill count. Knowledge questionnaire showed the highest sensitivity (68.1% and negative predictive value (82.2%, the lowest negative likelihood ratio (0.58 and post-test probability for a negative result (0.16. Serial analysis showed the highest specificity (77.4% and positive predictive value (40.1% as well as the highest positive likelihood ratio (1.8 and post-test probability for a positive result (0.39. Conclusion Medical Prescription Knowledge questionnaire showed the best performance as proxy measurement to identify non-adherence in type 2 diabetic patients regarding negative predictive value, negative likelihood ratio, and post-test probability for a negative result. However, Medical Prescription Knowledge questionnaire performance may change in contexts with higher

    Saigo, Barbara Woodworth

    The researcher collaborated with four high school biology teachers who had been involved for 2-1/2 years in a constructivism-based professional development experience that emphasized teaching for conceptual change and using classroom-based inquiry as a basis for making instructional decisions. The researcher and teachers designed a five-day instructional unit on biosystematics using two contrasting approaches, comprising the treatment variable. The "traditional" unit emphasized lecture, written materials, and some laboratory activities. The "constructivist" unit emphasized a specific, inquiry-based, conceptual change strategy and collaborative learning. The study used a quasi-experimental, factorial design to explore impact of instructional approach (the treatment variable) on student performance (the dependent variable) on repeated measures (three) of a biology concept test. Additional independent variables considered were gender, cumulative GPA, and the section in which students were enrolled. Scores on the biology concept test were compiled for the 3 constructivist sections (N = 44) and the 3 traditional sections (N = 42). Analysis of Covariance (ANCOVA) was applied. The main findings in regard to the primary research question were that instructional approach did not have a significant relationship to immediate post test scores or gain, but that one month after instruction students in the constructivist group demonstrated less loss of gain than those in the traditional group; i.e., their longer-term retention was greater. Also, GPA*instructional approach effects were detected for post-post-test gain. GPA and gender were significantly associated with pre-test, post-test, and post-post scores; however, in terms of change (gain) from pre-test to post-test and pre-test to post-post-test, GPA and gender were not significant effects. Section was a significant effect for all three tests, in terms of both score and gain. Gender*section effects were detected for post-test

    A thermal-hydraulic integral effect test facility, ATLAS was constructed at the Korea Atomic Energy Research Institute (KAERI). The ATLAS is a 1/2 reduced height and 1/288 volume scaled test facility based on the design features of the APR1400. The simulation capability of the ATLAS for major design basis accidents (DBAs), including a large-break loss-of-coolant (LBLOCA), DVI line break and main steam line break (MSLB) accidents, is evaluated by the best-estimate system code, MARS, with the same control logics, transient scenarios and nodalization scheme. The validity of the applied scaling law and the thermal-hydraulic similarity between the ATLAS and the APR1400 for the major design basis accidents are assessed. It is confirmed that the ATLAS has a capability of maintaining an overall similarity with the reference plant APR1400 for the major design basis accidents considered in the present study. However, depending on the accident scenarios, there are some inconsistencies in certain thermal hydraulic parameters. It is found that the inconsistencies are mainly due to the reduced power effect and the increased stored energy in the structure. The present similarity analysis was successful in obtaining a greater insight into the unique design features of the ATLAS and would be used for developing the optimized experimental procedures and control logics.

    Establishing a proper design fire scenario is a challenging task and essential component for conducting fire safety design of buildings. A design fire scenario is a qualitative description of a fire with time identifying key events that characterize the fire (ignition, growth, flashover, fully-developed, and decay stages of fire). Proper fire safety design requires the appropriate selection of design fires against which the performance of the building is evaluated. The selection of the design fires directly impacts all aspects of fire safety performance, including the structural fire resistance, compartmentation against fire spread, egress systems, manual or automatic detection systems, suppression systems, and smoke control. The parameters affecting design fires include, the type, amount and arrangement of combustible materials, the ventilation conditions (air supply conditions, door/window open), and size of the compartment of fire origin. A design fire is a quantitative description of the characteristics of a fire, such as heat release rate (HRR), size of fire and its rate of spread, yield of products of combustion, and hot gas temperatures. Design fires are based on fire scenarios that replicate real fires. Six Computational Fluid Dynamics (CFD) numerical simulations were conducted in order to investigate the effect of fire load on fire dynamics in a) iso corner fire configuration b) IIT Delhi single compartment of a size of 5.0 m long, 5.0 m wide and 5.0 m high with doorway opening of 1m x 3m with centre fire of size 0.5 m x 0.5m. These types of simulation are carried out for deciding about the instrumentation scheme, safety aspect, and optimization of proposed experiments for National Fire Test Facility as pretest calculations. The simulations results are summarized in various identified applied parameter which are useful in terms of understanding the complex fire dynamics, validating the numerical tolls against experiments and using them (in form of values and correlation) for fire safety. The effect of change in fire intensity on temperatures (and other parameters like velocity, flame length, ceiling temperature etc) at various locations are observed. The present paper present formulation, salient feature and detailed results and discussion on various flow parameters. The major results of the present studies are as follows a) As burner heat load increases the plume velocity and velocity of air through opening increases due to which distribution rate of temperature increases b)The velocity plume increases exponentially with burner load c) Boundary flux on wall and ceiling is increases with load but the boundary flux on ceiling is greater than wall d) the temperature at opening is increases with load e) Net positive flow plume is high at bottom but at the top the positive flow of plume is low due to back circulation of plume with vortex formation f) The flame height increases with fire load. The flame height calculated in above table matches Heskestad correlation F/D=-2.04+6.62Q*Λ0.4g) As fire load increases the flame become discontinuous. (author)

    2013-01-01

    In the framework of the FP7 MAXSIMA European project, the COMPLOT (COMPonent LOop Testing) LBE experimental facility is employed for thermal-hydraulic experiments aimed to test and qualify, among other components, a buoyancy driven safety/control rods (SR/CR) system, as key components for the safe operation of the MYRRHA reactor. This paper focuses mainly on a simplified CFD representation of the SR test section outlet in order to optimise it for the testing program. Parametric cases, associated with different positions of the SR assembly have been set up and analysed. A quasi-static analysis has been performed for each case, accounting for the LBE volume displaced by the insertion of the SR bundle, by introducing appropriately positioned additional mass sources. Velocity and pressure fields, as well as pressure drop magnitudes and mass flow rates through relevant guide tube hole outlets have been calculated and compared. The CFD analysis proved that the outer boundary of the test section does not impact the expected performance of the SR (rapid transient downward insertion). Preliminary simulations reproducing the timely repositioning of the SR/CR in COMPLOT using procedures of automatic volume mesh regeneration, consistently with the rod imposed displacement, are illustrated.

    The study aims to investigate two kinds of treatment in patients suffering from irritable bowel syndrome (IBS) and consequently compares its efficacy on improving the symptoms and mental health of patients; one with just medical treatment and another through a combination of psychotherapy and medical treatment. Applying general sampling, 50 IBS patients were selected from among those who used to refer to a Gastroenterology Clinic. After physical and mental evaluations based on ROME-II scale and SCL-90-R questionnaires, the subjects were randomly superseded into: the control group with medical treatment and, the case group with a combination of medical and psychological treatments. The acquired data were then analyzed through t-test and Mann-Whitney U-test. The findings show that the mental health of patients receiving cognitive behavioral therapy along with the medical treatment was higher than those of the control group at post-test level. It was observed that the therapy reduces the disability caused by IBS. Comparatively, while the cognitive therapy and medical treatments cured 80% of the patients, those receiving cognitive therapy alone showed an extensive reduction of symptoms. Considering the role of cognitive behavioral therapy, it is therefore recommend that such patients be managed by a combined team of gastroenterologists and psychologists.

    This report deals with a CORA-9 post-test-calculation with the computer-code RELAP5/SCDAP Mod.2.5 Ver.3f. It is the second technical report concerning the BMFT founded project ''Comparative Assessment of Different Computer Codes for Severe Accident Analysis. Contribution to the ATHLET/SA-Code Development'', which is performed at the ''Department of Nuclear and New Energy Systems (NES)'' at the Ruhr-University of Bochum. Three main phases during the temperature transient in CORA-9, namely the heatup phase, the escalation phase and the cooldown phase are covered by the calculations. The computations confirm that the governing phenomena, heat up, oxidation with the onset of the temperature excursion due to Zircaloy/steam reaction, and the cooldown phase are modeled satisfactorily by RELAP5/SCDAP. Investigations indicate that code underpredictions of the cladding surface temperature during the heatup phase are probably due to condensation effects occuring in the thermal hydraulic volumes.

    Full Text Available INTRODUCTION: This study aimed to evaluate the effect of the neural mobilization technique on electromyography function, disability degree, and pain in patients with leprosy. METHODS: A sample of 56 individuals with leprosy was randomized into an experimental group, composed of 29 individuals undergoing treatment with neural mobilization, and a control group of 27 individuals who underwent conventional treatment. In both groups, the lesions in the lower limbs were treated. In the treatment with neural mobilization, the procedure used was mobilization of the lumbosacral roots and sciatic nerve biased to the peroneal nerve that innervates the anterior tibial muscle, which was evaluated in the electromyography. RESULTS: Analysis of the electromyography function showed a significant increase (p<0.05 in the experimental group in both the right (Δ%=22.1, p=0.013 and the left anterior tibial muscles (Δ%=27.7, p=0.009, compared with the control group pre- and post-test. Analysis of the strength both in the movement of horizontal extension (Δ%right=11.7, p=0.003/Δ%left=27.4, p=0.002 and in the movement of back flexion (Δ%right=31.1; p=0.000/Δ%left=34.7, p=0.000 showed a significant increase (p<0.05 in both the right and the left segments when comparing the experimental group pre- and post-test. The experimental group showed a significant reduction (p=0.000 in pain perception and disability degree when the pre- and post-test were compared and when compared with the control group in the post-test. CONCLUSIONS: Leprosy patients undergoing the technique of neural mobilization had an improvement in electromyography function and muscle strength, reducing disability degree and pain.

    Anorexia nervosa has been related to alterations in brain activity in terms of hyperactive EEG patterns. This case report illustrates the principles and results of a five-week neurofeedback treatment in a 29-year-old woman suffering from anorexia nervosa. A neurofeedback protocol to enhance alpha activity (8 - 12 Hz) was developed and conducted additionally to the standardized treatment for eating disorders in training sessions twice a week. Pre- and post-test measurements included resting state EEG measurements and a psychological test battery. The results show improvements from pre- to post-test in eating disorder psychopathology including psychological wellbeing, emotional competence, and eating behavior traits. In addition, a decrease in theta power (4 - 7 Hz), a well-known trait marker of anorexia nervosa, was measured. However, our data should be interpreted with caution because this is a single case study. Nevertheless, this report documents the practicability and method of neurofeedback as treatment adjunct in eating disorders from the clinical perspective. Although the use of neurofeedback in the treatment of anorexia nervosa is recommended in literature, empirical studies are still lacking. Randomized controlled trials to evaluate short- and long-term effects of neurofeedback are needed. © Georg Thieme Verlag KG Stuttgart · New York.

    2008-12-15

    The MEGAwatt PIlot Experiment (MEGAPIE) project was started in 2000 to design, build and operate a liquid metal spallation neutron target at the power level of 1 MW. The project is an important step in the roadmap towards the demonstration of the Accelerator-Driven System (ADS) concept and for high power molten metal targets in general. In an ADS the spallation target is placed inside a sub-critical reactor core. The role of the spallation target is to provide the extra neutrons needed by the sub-critical core to keep the reactor working. Since an ADS is a fast neutron system, there is no moderation and the spallation neutron spectrum is therefore a typical fast spectrum. For a sub-critical core with k{sub eff} = 0.95, a strong neutron source is needed, and in the roadmap an accelerator current higher than 10 mA is indicated as baseline parameter for the experimental ADS. The choice of the accelerator current and energy depends primarily on the number of neutrons that need to be generated, and that are used to drive the reactor. With the 590 MeV cyclotron delivering a continuous beam on target with a current up to 1.8 mA, SINQ was chosen for the MEGAPIE experiment as the most powerful spallation neutron source in the world, with a proton beam power on target that can reach 1 MW. Up to MEGAPIE all SINQ targets were based on a bundle of heavy material rods (full zircaloy, steel rods filled with Pb, zircaloy rods filled with Pb) cooled by a flow of heavy water. For the MEGAPIE target a loop of about 82 litres of lead-bismuth eutectic (LBE) circulates enclosed by a steel structure. The target is about 5 m long and the LBE is made circulating by means of a main electromagnetic pump. The neutronic performance was deduced from flux measurements done at different positions and distances from the spallation target, because the neutron yield (number of neutrons per incoming proton) cannot be directly measured. The presence of the heavy water moderator in the SINQ facility changes the spectrum, from a fast one to a prevalently thermal one, in most of the measurement points (with the exception of measurements performed near the centre of the target). The neutronic performance of a liquid target is compared to the standard solid targets used in SINQ. In the MEGAPIE experiment the neutron flux is measured in the close proximity of the spallation zone by means of innovative micro fission chambers which give a current proportional to the neutron yield. Coupled with very detailed Monte Carlo simulations, these integral measurements provide accurate data on the neutron generation. Spallation residues accumulation or temperature influence the neutron balance and the neutron energy spectrum. Overall, the results obtained with the 3 codes FLUKA 2006.3b, MCNPX 2.5.0 and SNT are consistent. The comparison was performed for the LBE, where the results compare well, and for the structure of the target for which the discrepancies are larger. The reason is related to the different origin of the activation: residual nuclei in LBE are mainly due to spallation reactions, while target structure activation is mainly due to low-energy neutron capture. The latter is sensitive to the simulated thermalization process and to the capture cross sections data used. By comparing measurements and calculations of the neutron flux, differences of 20% were found for thermal fluxes. For epithermal flux the 'background' of neutrons with E < 1 MeV is larger with the liquid metal target than for the solid ones. For fast neutron (E > 1 MeV) a disagreement of a factor 2-3 (depending on the chamber position) was found. It seems that the calculation of the fission rates is not correct due to the inherent difficulty of reproducing the mixed neutron spectrum, with strong thermal, epithermal and fast components at the detector locations. MEGAPIE has a neutronic performance higher than the solid targets of SINQ. The performance change between the two different solid targets and MEGAPIE has been correctly reproduced. To achieve a good accuracy in the calculation of the neutronic performance of an ADS system, an accurate definition of the geometrical model taking into account the influence of structural materials is of primary importance. The results depend also on the beam profile used in the simulations, at least for the flux calculations close to the target interaction point. Radioactive nuclides produced in liquid metal targets are transported into hot cells, pumps or close to electronics with radiation sensitive components. Besides the considerable amount of decay {gamma} activity in the irradiated liquid metal, a significant amount of the Delayed Neutron (DN) precursor activity accumulates in the target fluid. The transit time of a liquid metal target being as short as a few seconds, DNs may contribute significantly to the activation and dose rates. The importance of the DN issues in liquid metal targets is confirmed. Another problem is the gas production and release in an ADS target, the proton beam generating a large amount of gas by spallation reactions. A large amount of Po isotopes, volatile at relatively high temperatures, are produced in the LBE. The gas production was measured by {gamma} spectroscopy. The release rates of noble gases in MEGAPIE are at the % level after 1-2 days of operation, while the release becomes almost complete weeks after the beginning of operation. Pressure increase in the cover gas could be reproduced with calculations within a factor of 2. The effect of the impurities in the radionuclide inventory of the LBE, using the actual chemical composition of the LBE used in MEGAPIE, is minimal.

    The design, performance analysis, and key attributes of the Modular Isotopic Thermoelectric Generator (MITG) were described in a 1981 IECEC paper; and the design, fabrication, and testing of prototypical MITG test assemblies were described in preceding papers in these proceedings. Each test assembly simulated a typical modular slice of the flight generator. The present paper describes a detailed thermal-stress analysis, which identified the causes of stress-related problems observed during the tests. It then describes how additional analyses were used to evaluate design changes to alleviate those problems. Additional design improvements are discussed in the next paper in these proceedings, which also describes revised fabrication procedures and updated performance estimates for the generator

    Two transient tests in one of the FFTF secondary heat transport loops were performed (March to May 1979) in order to verify that the transition to natural convective flow could be effected from near isothermal refueling conditions without excessive cooling at the air dump heat exchangers. Following the tests, the best estimate computer model was calibrated against the data, yielding in the process insights about the loop parameters and the probable suitability of the model structure. Key empirical parameters of pressure drop and heat loss were found to be at 62% and 81% of the pretest safety evaluation model parameter values, respectively. Pretest piping thermal transport and flow calculational models required no further revision to produce good agreement with the test data. Additional detail in the air dump heat exchanger heat loss model, accounting for long structural thermal time constants, was found to be necessary to obtain model agreement with transient outlet temperature data. The pretest model had conservatively employed steady state heat losses for transient calculations

    Research about the implementation of the Peer Assisted Learning (PAL) strategy in Plant Physiology lecture has carried out, in which it aims to improve students’ physiologic literacy. The PAL strategy began with a briefing by the lecturers to the students tutor about pretest questions, followed by the interaction between student tutors with their peers to discuss response problems, terminated by answering responsiveness questions individually. This study used a quasi-experimental method, one - group pre-test post-test design. This design includes a group of students observed in the pre-test phase (tests carried out before PAL treatment) which is then followed by treatment with PAL and ends with post-test. The other students group (control) was given the pre-test and post-test only. The results showed that the PAL strategy can increase student’s physiologic literacy significantly. One of the weaknesses of students’ physiologic literacy is that they have not been able to read the graph. The faculties are encouraged to begin introducing and teaching material using a variety of strategies with scientific literacy aspects, for example teaching research-based material. All students respond positively to the PAL strategy.

    Full Text Available This research aims to find out whether Herringbone Technique can developEFL students’ reading comprehension or not, especially in finding the main idea and supporting details in a recount text. The literature notes that Herringbone is known to be one of the techniques that can helpstudents to find important information and main idea in a text by seeking for answers on six comprehension questions on a diagram, viewed such as a fish’s skeleton. The sample of this research was 30 second grade junior high school students. The researchers employed simple random sampling to choose the sample. It further used the quantitative experimental approach with the pre-experimental design in the form of one group pre-test-post-test design.Pre-test was given before treatments, while post-test was given after the students were taught reading by using the Herringbone Technique. Each pre-test and post-test consisted of ten questions. The statistical formulas were used to analyze the data from the students tests’ scores. The mean score of pre-test was 59 and the post-test was 76. Futhermore, the result of t-test was 10.15, while the critical value of 0.05 significant level was 2.045, with the degree of freedom of 29. Since t-test (10.15 was higher than t-table (2.045, this study concludes that this technique could increase the EFL students’ reading comprehension.Despite in practice the researchers found that this technique decreased the students’ efforts in note-taking, however it did not inhibited them in obtaining improved scores in their reading tests.

One-hundred-eighty-seven hyperthyroid patients who were sent for radioactive iodine treatment at Division of Nuclear Medicine, Department of Radiology, Faculty of Medicine Siriraj Hospital were requested to fill the questionnaires before and after receiving the information about radioiodine treatment. The questionnaires consisted of 15 questions of which the first five were about the attitude to radiation and radioiodine treatment. The rest was about an information on hyperthyroidism and radioiodine treatment. For data analysis, firstly the percentage of correct answer of each question was calculated and compared between pre-and post-test. Secondly all patients were categorized into 2 groups according to their education: up to high school, and undergraduate or higher. The attitude and the understanding about radioiodine treatment were analyzed in each group. If the average percentage was greater than 80, patients has positive attitude of good understanding. The results showed that post-test gives higher percentages of correct answers for all questions with an average of 24.6% improvement. For up to high school group, the attitude improved from 81.6% to 98.6% and the understanding about radioiodine treatment improved from 92.2% to 100%. Similarly, for the undergraduate or higher group, the attitude improved from 87% to 97.8% and the understanding about radioiodine treatment was 100% for both pre- and post-intervention. It may be concluded that our education intervention is informative and improves the patients, attitude and understanding about radiation

Of those attending, 231 and 220 completed the pre-and post-tests, respectively. Overall, the mean pre-test score for knowledge-based questions was 74.3 and average post-test score was 94.2%, indicating a mean increase of 19.9% (P dengue recognition and management also increased. Non-US trained physicians and those who had treated more than ten dengue cases performed significantly better in the pre-test. Post-test scores did not differ by subgroup. The train-the-trainer approach with grand-rounds style presentations appear to be an effective intervention to improve knowledge of dengue among physicians.

    Terry, Brian H.

    In this quasi-experimental study, the researcher investigated the effectiveness of three tactual strategies and one non-tactual strategy of content specific vocabulary acquisition. Flash cards, task cards, and learning wheels served as the tactual strategies, and vocabulary review sheets served as a non-tactual strategy. The sample (n=85) consisted of all middle school students in a small high performing middle school located in the northern suburbs of New York City. All of the vocabulary words and terms came from the New York State Intermediate Level Science Core Curriculum. Pre-tests and post-tests were used to collect the data. A repeated measures ANOVA was conducted on the gain scores from each of the treatments. Multiple paired sample t-tests were conducted to analyze the results. Repeated measures ANOVAs were used to determine if there was a variance between the academic achievement levels of the students, gender, and grade level for each of the treatments. All of the treatments significantly improved the science achievement of the students, but significance was found between them. Significance was found between the achievement groups with the above average students attaining a higher mean on the pre-test and post-test for each treatment, whereas the below average students had the lowest mean on both assessments. The sixth grade students showed significant improvement over the seventh grade students while using the flash cards (p=.004) and learning wheel (p=.007). During the learning wheel treatment, the males scored significantly better (p=.021) than the females on the pre-test and post-test. During the worksheet treatment, significance (p=.034) was found between gender and achievement group. The below average male students had the greatest gain from the pre-test to the post-test, but the post-test mean was still the lowest of the groups. Limitations, implications for future research and current practice are discussed. Key words are: flash cards, task cards

    Background Provision and scale-up of high quality, evidence-based services is essential for successful international HIV prevention interventions in order to generate and maintain intervention uptake, study integrity and participant trust, from both health service delivery and diplomatic perspectives. Methods We developed quality assurance (QAC) procedures to evaluate staff fidelity to a cluster-randomized trial of the NIMH Project Accept (HPTN 043) assessing the effectiveness of a community-based voluntary counseling and testing strategy. The intervention was comprised of three components—Mobile Voluntary Counseling and Testing (MVCT), Community Mobilization (CM) and Post-Test Support Services (PTSS). QAC procedures were based on standardized criteria, and were designed to assess both provider skills and adherence to the intervention protocol. Supervisors observed a random sample of 5% to 10% of sessions each month and evaluated staff against multiple criteria on scales of 1–5. A score of 5 indicated 100% adherence, 4 indicated 95% adherence, and 3 indicated 90% adherence. Scores below 3 were considered unsatisfactory, and protocol deviations were discussed with the respective staff. Results During the first year of the intervention, the mean scores of MVCT and CM staff across the 5 study sites were 4 (95% adherence) or greater and continued to improve over time. Mean QAC scores for the PTSS component were lower and displayed greater fluctuations. Challenges to PTSS staff were identified as coping with the wide range of activities in the PTSS component and the novelty of the PTSS process. QAC fluctuations for PTSS were also associated with new staff hires or changes in staff responsibilities. Through constant staff monitoring and support, by Year 2, QAC scores for PTSS activities had reached those of MVCT and CM. Conclusions The implementation of a large-sale, evidence based HIV intervention requires extensive QAC to ensure implementation effectiveness

    Background and purpose: The purpose of this study was to investigate the comparative effects of a prediction/discussion-based learning cycle (HPD-LC), conceptual change text (CCT) and traditional instruction on 10th grade students' understanding of genetics concepts. Sample: Participants were 112 10th basic grade male students in three classes of the same school located in an urban area. The three classes taught by the same biology teacher were randomly assigned as a prediction/discussion-based learning cycle class (n = 39), conceptual change text class (n = 37) and traditional class (n = 36). Design and method: A quasi-experimental research design of pre-test-post-test non-equivalent control group was adopted. Participants completed the Genetics Concept Test as pre-test-post-test, to examine the effects of instructional strategies on their genetics understanding. Pre-test scores and Test of Logical Thinking scores were used as covariates. Results: The analysis of covariance showed a statistically significant difference between the experimental and control groups in the favor of experimental groups after treatment. However, no statistically significant difference between the experimental groups (HPD-LC versus CCT instruction) was found. Conclusions: Overall, the findings of this study support the use of the prediction/discussion-based learning cycle and conceptual change text in both research and teaching. The findings may be useful for improving classroom practices in teaching science concepts and for the development of suitable materials promoting students' understanding of science.

    Genetic testing is becoming increasingly available for adolescents who are undergoing cancer treatment or at risk of cancer predisposition syndromes. With this narrative review, we aimed to synthesize the evidence on psychosocial outcomes and adolescents' understanding of genetic testing-thus far, an underresearched topic. Both psychological benefits and harms of predictive testing were reported in adolescents from high-risk families. Harms were mainly related to cancer-specific distress and increased worries. Findings on genetic understanding were sparse. Future studies should focus on psychosocial outcomes and adolescents' understanding undergoing genetic testing and enabling access to genetic counseling pre-testing and post-testing.

  9. Accelerated treatment.

    Barkley, H T

    1985-05-01

    In the first third of this century, the prevailing concept was that malignant cells had a brief period of sensitivity and radiation treatments were ideally given in overall times of 2 weeks or less. Following the Second World War, routine treatment times were extended to 5 to 8 weeks to avoid severe acute normal tissue reactions and achieve higher tumor doses. In reaction to these prolonged overall times, a series of large-fraction, shortened-overall-time clinical experiments were attempted, with disastrous normal tissue effects and poor tumor control. More recently, attempts to accelerate treatment have been accomplished by utilizing multiple fractions per day or semicontinuous irradiation. Unfortunately, the majority of these attempts have been forced by the occurrence of unacceptable normal tissue reactions to significantly reduce total dose or introduce lengthy splits in treatment. These results suggest that in our current state of knowledge accelerated schedules be reserved for use in the treatment of rapidly proliferating neoplasms or for palliation.

    In a treatment analogue design, 44 moderately depressed volunteer subjects were divided randomly into four groups: attention-placebo; Gestalt empty chair dialogues designed to be personally relevant and high in affect; dialogues designed to be personally irrelevant and neutral in affect; and groups in which strong affect was encouraged, but no dialogues enacted. Groups met 1 hour per week for 4 weeks. Each group was pretested, post-tested, and follow-up tested with an abbreviated MMPI, the Depression Adjective Check List, and experimenter questionnaires. A series of 4 X 3 ANOVAs indicated significant main effects for time across all dependent variables. Also, anxiety and social introversion decreased over time in all groups. No other main or interactional effects were significant. These results suggest that mild depression, as well as anxiety and social introversion, dissipated over time and remained lower regardless of whether the subject had any treatment.

    Many students reach the middle school level without appropriate critical thinking skills. This has important implications for educators and the future workforce. This mixed methods quasi-experimental design study investigated the use of a science inquiry kit and its effect on the critical thinking skills and dispositions of elementary students. Third grade students and their six teachers were the participants in this study. Two instruments were used to evaluate students' critical thinking skills and dispositions. Post-test results for critical thinking skills indicated the comparison group had increased their means significantly. Evaluation of the treatment groups pre-test vs. post-test means indicated that there was a significant difference; although it was not as great as the difference between the comparison group's pre-test vs. post-test means. The instrument used to evaluate the students' critical disposition did not show a significant difference between the post-test means. The qualitative portion was conducted to discover the experiences, training, and pedagogy used to teach science inquiry and critical thinking skills. The data revealed that teachers had very limited experiences with training in either science inquiry or critical thinking skills; their pedagogy in both areas was also fairly limited. The teachers in the treatment group expressed that they were pleased with the use of the kit in regard to its influence on their students' content knowledge and critical thinking skills, and they felt that the students' critical thinking skills improved as a result of using the science inquiry kit. Recommendations include repeating the use of the science kit with other third grade classes and with older students to discover if similar results are obtained. Additional information should be obtained from other teachers regarding their training in science inquiry and critical thinking skills to determine if this is a local issue or if it is a pervasive theme.

    2004-01-01

    The CONSTOR registered family of steel-concrete-steel sandwich cask designs have been developed to fulfil both the internationally valid IAEA criteria for transportation and the requirements for long-term intermediate storage in the US and various European countries. A comprehensive drop testing programme using a full-scale prototype test cask (CONSTOR registered V/TC) has been developed as part of the application for a transport license in both Germany and the US. The drop tests using the full-scale cask will be performed by BAM at test facilities in Horstwalde. The tests will include five different 9m drops onto flat unyielding targets and seven different 1m drops onto a punch. The first drop test, a 9m side drop, will be performed during PATRAM 2004. The other drop tests will take place during the following year. The development of the cask design and the formulation of the drop test programme has been supported by an extensive series of finite element analyses. The objectives of the finite element analyses were; to provide an intermediate step in demonstrating the performance of the CONSTOR registered in fulfilling the requirements of 10 CFR 71 and the IAEA transport regulations. To justify the selection of drop tests. To predict the performance of V/TC during the drop tests. To estimate the strain and acceleration time histories at measuring points on the test cask and to aid in the setting up of the test instrumentation. To develop an analysis model that can be used in future safety analyses for transport and storage license applications and which can confidently be used to demonstrate the performance of the package. This paper presents an overview of the analyses performed, including a summary of all the different drop orientations that were considered.

    Oak Ridge National Laboratory (ORNL) is conducting a series of numerical analyses to simulate a large scale mock-up experiment planned within the European Network for Structural Integrity for Lifetime Management non-RPV Components (STYLE). STYLE is a European cooperative effort to assess the structural integrity of (non-reactor pressure vessel) reactor coolant pressure boundary components relevant to ageing and life-time management and to integrate the knowledge created in the project into mainstream nuclear industry assessment codes. ORNL contributes work-in-kind support to STYLE Work Package 2 (Numerical Analysis/Advanced Tools) and Work Package 3 (Engineering Assessment Methods/LBB Analyses). This paper summarizes the current status of ORNL analyses of the STYLE Mock-Up3 large-scale experiment to simulate and evaluate crack growth in a cladded ferritic pipe. The analyses are being performed in two parts. In the first part, advanced fracture mechanics models are being developed and performed to evaluate several experiment designs taking into account the capabilities of the test facility while satisfying the test objectives. Then these advanced fracture mechanics models will be utilized to simulate the crack growth in the large scale mock-up test. For the second part, the recently developed ORNL SIAM-PFM open-source, cross-platform, probabilistic computational tool will be used to generate an alternative assessment for comparison with the advanced fracture mechanics model results. The SIAM-PFM probabilistic analysis of the Mock-Up3 experiment will utilize fracture modules that are installed into a general probabilistic framework. The probabilistic results of the Mock-Up3 experiment obtained from SIAM-PFM will be compared to those results generated using the deterministic 3D nonlinear finite-element modeling approach. The objective of the probabilistic analysis is to provide uncertainty bounds that will assist in assessing the more detailed 3D finite-element solutions and to also assess the level of confidence that can be placed in the best-estimate finite-element solutions.

    In this study, cognitive interviewing methods were used to test targeted questionnaire items from a battery of quantitative instruments selected for a large multisite trial of supported housing interventions for homeless individuals with mental disorders. Most of the instruments had no published psychometrics in this population. Participants were 30 homeless adults with mental disorders (including substance use disorders) recruited from service agencies in Vancouver, Winnipeg, and Toronto, Canada. Six interviewers, trained in cognitive interviewing methods and using standard interview schedules, conducted the interviews. Questions and, in some cases, instructions, for testing were selected from existing instruments according to a priori criteria. Items on physical and mental health status, housing quality and living situation, substance use, health and justice system service use, and community integration were tested. The focus of testing was on relevance, comprehension, and recall, and on sensitivity/acceptability for this population. Findings were collated across items by site and conclusions validated by interviewers. There was both variation and similarity of responses for identified topics of interest. With respect to relevance, many items on the questionnaires were not applicable to homeless people. Comprehension varied considerably; thus, both checks on understanding and methods to assist comprehension and recall are recommended, particularly for participants with acute symptoms of mental illness and those with cognitive impairment. The acceptability of items ranged widely across the sample, but findings were consistent with previous literature, which indicates that "how you ask" is as important as "what you ask." Cognitive interviewing methods worked well and elicited information crucial to effective measurement in this unique population. Pretesting study instruments, including standard instruments, for use in special populations such as homeless individuals with mental disorders is important for training interviewers and improving measurement, as well as interpreting findings.

    The U.S. Department of Energy's (DOE) Yucca Mountain Site Characterization Project (YMP) is investigating the suitability of the Topopah Spring tuff in the thick vadose zone at Yucca Mountain, Nevada, as a host rock for permanent disposal of high-level radioactive waste. As part of the YMP, a group of field tests, referred to as the Large Block Test (LBT), will be conducted on a large electrically heated block of Topopah Spring tuff, isolated at Fran Ridge, Nevada Test Site. The block, which will be 3 x 3 m in horizontal dimensions and 4.5 m in height, will be heated by electrical heaters. The goals of the LBT axe to gain information on the coupled thermal-mechanical-hydrological-chemical processes active in the near-field environment of a repository; to provide field data for testing and calibrating models; and to help the development of measurement systems and techniques. This progress report presents results of on-going numerical modeling calculations carried out in support of the LBT design. An equivalent continuum model with an upper boundary temperature of 60 degrees C was used to simulate the hydrothermal response of the block to heating over a one-year period. The total heating power was started at 1500 W and later reduced to maintain an approximately uniform temperature of 138-140 degrees C. For a homogeneous bulk permeability case, the results show the formation of a distinct dry-out zone in and around the heater plane, and well-developed condensation zones above and below the heater plane. For a heterogeneous permeability distribution, the condensation zone above the heater plane was not well developed. This difference in results suggests that water saturation changes might be sensitive to changes in bulk permeability distribution. Rock temperatures were almost unaffected by permeability distribution. Heat flow was dominated by conduction. No liquid flow through the top of the block was predicted

    The US Department of Energy's (DOE) Yucca Mountain Site Characterization Project (YMP) is investigating the suitability of the Topopah Spring tuff in the thick vadose zone at Yucca Mountain, Nevada, as a host rock for permanent disposal of high-level radioactive waste. As part of the YMP, a group of field tests, called the Large Block Test (LBT), will be conducted on a large electrically heated block of Topopah Spring tuff. The block will be heated by electrical heaters. The goals of the LBT are to gain information on the coupled thermal-mechanical-hydrological-chemical processes that will be active in the near-field environment of a repository; to provide field data for testing and calibrating models; and to help in the development of measurement systems and techniques. In this second progress report, we present results of the final set of numerical modeling calculations performed in support of the LBT design. The results include block temperatures and heat fluxes across the surfaces. The results are applied primarily to the design of guard heaters to enforce adiabatic conditions along the block walls. Conduction-only runs are adequate to estimate the thermal behavior of the system, because earlier calculations showed that heat transfer in the block is expected to be dominated by conduction. In addition, conduction-only runs can be made at substantially shorter execution times than full hydrothermal runs. We also run a two-dimensional, hydrothermal, discrete fracture model, with 200-μm vertical fractures parallel to the heaters and occurring at a uniform spacing of 30 cm. The results show the development of distinct dryout and recondensation zones. The dryout zones are thickest at the fractures and thinnest in the matrix midway between the fractures

    In the frame of LEADER project (Lead-cooled European Advanced Demonstration Reactor), a new configuration of the steam generator for ALFRED (Advanced Lead Fast Reactor European Demonstrator) was proposed. The new concept is a super-heated steam generator, double wall bayonet tube type with leakage monitoring [1]. In order to support the new steam generator concept, in the framework of Horizon 2020 SESAME project (thermal hydraulics Simulations and Experiments for the Safety Assessment of MEtal cooled reactors), the ENEA CIRCE pool facility will be refurbished to host the HERO (Heavy liquid mEtal pRessurized water cOoled tubes) test section to investigate a bundle of seven full scale bayonet tubes in ALFRED-like thermal hydraulics conditions. The aim of this work is to verify thermo-fluid dynamic performance of HERO during the transition from nominal to natural circulation condition. The simulations have been performed with RELAP5-3D© by using the validated geometrical model of the previous CIRCE-ICE test section [2], in which the preceding heat exchanger has been replaced by the new bayonet bundle model. Several calculations have been carried out to identify thermal hydraulics performance in different steady state conditions. The previous calculations represent the starting points of transient tests aimed at investigating the operation in natural circulation. The transient tests consist of the protected loss of primary pump, obtained by reducing feed-water mass flow to simulate the activation of DHR (Decay Heat Removal) system, and of the loss of DHR function in hot conditions, where feed-water mass flow rate is absent. According to simulations, in nominal conditions, HERO bayonet bundle offers excellent thermal hydraulic behavior and, moreover, it allows the operation in natural circulation.

    In the treatment of wastes, such as liquid radioactive effluents, it is known to remove radionuclides by successive in situ precipitation of cobalt sulphide, an hydroxide, barium sulphate and a transition element ferrocyanide, followed by separation of the thereby decontaminated effluent. In this invention, use is made of precipitates such as obtained above in the treatment of further fresh liquid radioactive effluent, when it is found that the precipitates have additional capacity for extracting radionuclides. The resulting supernatant liquor may then be subjected to a further precipitation treatment such as above. Decontamination factors for radionuclides of Ce, Ru, Sr and Cs have been considerably enhanced. (author)

    ABSTRACT Tuberculosis treatment remains a challenge due to the need to consider, when approaching it, the context of individual and collective health. In addition, social and economic issues have been shown to be variables that need to be considered when it comes to treatment effectiveness. We conducted a critical review of the national and international literature on the treatment of tuberculosis in recent years with the aims of presenting health care workers with recommendations based on the situation in Brazil and better informing decision-making regarding tuberculosis patients so as to minimize morbidity and interrupt disease transmission.

    Developing pharmacotherapies to treat alcohol dependence and associated health problems traditionally has been based on gaining a better understanding of the neuroscience underlying alcohol-drinking behavior. To date, three medications have been approved for the treatment of alcohol dependence: disulfiram (Antabuse®), naltrexone (Revia®, Vivitrol®, and Naltrel®), and acamprosate (Campral®). However, these medications have modest efficacy, and there is a great need for newer medications that target different neurochemical systems and which could be used either as adjunctive treatments or to treat subpopulations of drinkers. Furthermore, it also is important to improve current treatment options by understanding and incorporating differences in how people with certain genes respond to medication (i.e., pharmacogenetic differences).

    Full Text Available This paper is a quasi-experimental research. It was aimed to investigate the significant difference on vocabulary achievement between two groups who were taught by using Mind Mapping strategy and those who were taught by using Making Notes strategy. The subjects of this study were the students in class 5B and 5D of An-Nissa Islamic Billingual Elementary School of Semarang. 5B was the experimental group and 5D was the control group. In this research, I gave them a pre-test, treatments, and a post-test. I used the same instrument in the pre-test for both groups. They were asked to answer some questions of vocabulary test. The treatments were given in three meetings. The treatment used in the experimental group was Mind Mapping strategy, while the treatment in the control group was Making Notes strategy. The post-test in both groups were conducted after the treatments by using the same instrument as the pre-test but the position of question numbers were reshuffled. The result of the test was analyzed by using t-test formula to know the difference of the students‘ achievement in vocabulary between two groups. The analysis of the test result showed that the experimental group got better score than the control group. That calculation revealed that the hypothesis 1 (Ha was accepted and the hypothesis 2 (Ho was rejected. Based on the proven hypotheses, I concluded that Mind Mapping strategy is more effective to be implemented in teaching vocabulary than Making Notes strategy.

    SUMMARY Considered to be an emerging endemic mycosis in Latin America, paracoccidioidomycosis is characterized by a chronic course and involvement of multiple organs in immunocompromised hosts. Infection sequelae are mainly related to pulmonary and adrenal insufficiency. The host-parasite interaction results in different expressions of the immune response depending on parasite pathogenicity, fungal load and genetic characteristics of the host. A few controlled and case series reports have shown that azoles and fast-acting sulfa derivatives are useful treatment alternatives in milder forms of the disease. For moderate/severe cases, more prolonged treatments or even parenteral routes are required especially when there is involvement of the digestive tract mucosa, resulting in poor drug absorption. Although comparative studies have reported that shorter treatment regimens with itraconazole are able to induce cure in chronically-infected patients, there are still treatment challenges such as the need for more controlled studies involving acute cases, the search for new drugs and combinations, and the search for compounds capable of modulating the immune response in severe cases as well as the paradoxical reactions.

    Many well-researched treatments for depression exist. However, there is not yet enough evidence on whether these therapies, designed for the treatment of depression, are also effective for reducing suicidal ideation. This research provides valuable information for researchers, clinicians, and suicide prevention policy makers. Analysis was conducted on the Treatment for Depression Research Collaborative (TDCRP) sample, which included CBT, IPT, medication, and placebo treatment groups. Participants were included in the analysis if they reported suicidal ideation on the HRSD or BDI (score of ≥1). Multivariate linear regression indicated that both IPT (b=.41, pdepression these treatment effects were no longer significant. Moderate Cohen׳s d effect sizes from baseline to post-test differences in suicide score by treatment group are reported. These analyses were completed on a single suicide item from each of the measures. Moreover, the TDCRP excluded participants with moderate to severe suicidal ideation. This study demonstrates the specific effectiveness of IPT and medications in reducing suicidal ideation (relative to placebo), albeit largely as a consequence of their more general effects on depression. This adds to the growing body of evidence that depression treatments, specifically IPT and medication, can also reduce suicidal ideation and serves to further our understanding of the complex relationship between depression and suicide.

    This study aimed to investigate whether psychological disorders and symptom severity hamper weight loss in obese adolescents and explored the effect of evidence-based adolescent obesity treatment on psychological disorders and symptom severity. Participants were 66 adolescents admitted for a 10-month obesity treatment programme. At the start of treatment both clinical interviews and self-report questionnaires were administered. Weight loss was registered at several time points. Half of the sample was invited to complete questionnaires and be interviewed once again at the end of the programme. Baseline degree of overweight was the strongest predictor of weight loss. The presence of at least one psychological disorder appeared a negative predictor of weight loss after four months. At post-test, a decrease in eating, shape and weight concern and binge eating episodes was demonstrated. A similar trend was found for internalizing symptoms. All eating disorders resolved, but a substantial number of adolescents still suffered from psychological disorders at the end of treatment. During inpatient obesity treatment, youngsters who are more severely obese lose most weight. In girls and in adolescents suffering from psychological disorders, long-term care should be the aim to prevent an experience of failure. From a psychological health perspective, the inclusion of psychotherapy during inpatient obesity treatment for adolescents suffering from psychiatric disorders is worth considering. All together, the findings of this study demonstrate the importance of adopting both a medical and a psychological perspective on obesity (treatment) in youth.

    Majority of people in Simbang kulon Indonesia almost every citizen who batik artisans, by utilizing river water to wash batik, as well as a place to dispose of waste. As a result, the river is polluted. However, there are no steps to educate young generation especially students to care about the environment. Therefore, project-based learning is appropriate approach. This research was intended to provide a description of the study of project-based chemistry on redox reaction material and its application for the waste treatment of class X MA Salafiyah Simbang Kulon Pekalongan. The implementation of project-based chemistry study of redox reaction material and its application on batik waste treatment in class X MA Salafiyah Simbang Kulon Pekalongan can be seen from several aspects, such as: (1) planning stage: includes preparation of learning planning activities such as RPP preparation of LKS etc, (2) Implementation stage: this stage consists of classroom discussion, and batik waste treatment project (3) evaluation stage. This evaluation was done by the researcher on the results of project-based learning to measure the level of effectiveness of learning with the achievement of students' competencies in terms of cognitive, that is by doing post-test and interview. The end result was to compare the results of the pre-test of learners who achieve the value of KKM with the results of post-test learners who reached the KKM value of 6.8. The results showed that: the effectiveness level of learning chemistry-based projects redox reaction material and its application on the batik waste treatment of class X MA Salafiyah Simbang Kulon Pekalongan was very high, this can be seen from the comparison of the percentage of school KKM achievement between the value of pre-test results with value of post-test result was difference of pre-test result 8,33% with result of post-test 91,66%, so difference was 81,26%. These results were then reinforced by the results of the researcher

    This study sought to evaluate a new stated-preference instrument to prioritize multiple treatment goals among people with recent onset schizophrenia. A draft survey instrument was developed to assess preferences for 13 key treatment goals that were identified based on the literature. The survey incorporates best-worst scaling (BWS), which shows repeated subsets comprising 4 of the 13 goals, and respondents identify which is most important and which is least important to them. Pre-test interviews were conducted in the UK, Italy, and Germany among people aged 18 to 35 diagnosed with schizophrenia within the past 5 years. Specifically, participants completed the instrument online in their native language, followed by a telephone interview to provide feedback on the clarity, relevance, and comprehensiveness of the survey. The interview data were analyzed to assess interpretation and content validity of the survey. Fifteen participants (five per country) provided feedback (mean age = 31; 60% male). Feedback was comparable across countries and confirmed that the key treatment goals assessed were relevant and meaningful. Probing by interviewers ascertained that respondents interpreted the questions appropriately and identified the treatment goals that were most and least important to them. Based on the characterization of the goals, a conceptual model was developed illustrating hypothesized associations among them. The results confirm that the BWS methodology and key treatment goals in this new instrument are appropriate for use in recent onset schizophrenia. These results will help guide measurement of patient-relevant endpoints in future studies.

    There are no data on social acceptability of scoliosis. Aim. To elicit evidence-based opinions on therapeutic strategies for adolescent idiopathic scoliosis in a sample of families with not affected children, so to understand the social perception of this issue. Design. Cross-sectional study. Setting. Secondary schools in 4 northern Italian regions. Participants. Parents of children in the age group at risk of and not affected by scoliosis (Pre-test group = 100, Study group = 3,162). Interventions. Questionnaire: five specific and evidence-based questions regarding scoliosis treatment options and a socio-demographic section. Methodology. "Role-playing" in which it was required to normal people to answer what they would have chosen if they had been in the situation proposed. Main outcome measures. Perception of acceptability of treatments for adolescent idiopathic scoliosis in the general population (social acceptability). The families support the use of screening (94.8%) at school, immediate bracing (76.4%) for scoliosis with a 60% risk of progression, but also therapeutic exercises (86.9%) in cases with a 25% risk of progression. There is a growing tendency to consider not only the efficacy, effectiveness and efficiency of treatments, but also their acceptability. This patient-centred aspect is especially more important in areas (like adolescent idiopathic scoliosis) in which there is some evidence on the efficacy of treatments, but not strong and definitive (RCTs). Adolescent idiopathic scoliosis treatments should thus be carefully considered also in the light of their social acceptability.

    Full Text Available Quality of life on Earth in the future will largely depend on the amount of safe water. As the most fundamental source of life, water is relentlessly consumed and polluted. To halt this trend, many countries are taking extensive measures and investing substantial resources in order to stop the contamination of water and return at least tolerably good water quality to nature. The goal of water purification is to obtain clean water with the sewage sludge as a by-product. Clean water is returned to nature, and further treatment of sludge may be subject to other procedures. The conclusion of this paper is simple. The procedure with purified water is easily achievable, purified water is discharged into rivers, lakes and seas, but the problem of further treatment of sludge remains. This paper presents the basic methods of wastewater treatment and procedures for processing the products from contaminated water. The paper can serve as a basis for further elaboration. Water Pollution In order to ensure normal life of living creatures, the water in which they live or the water they use must have a natural chemical composition and natural features. When, as a result of human activities, the chemical composition of water and the ratio of its chemical elements significantly change, we say that water is polluted. When the pollutants come from industrial plants, we are talking about industrial wastewater, and when they come from households and urban areas, we are talking about municipal wastewater. Both contain a huge amount of pollutants that eventually end up in rivers. Then, thousands of defenseless birds, fish and other animals suffer, and environmental consequences become immeasurable. In addition, the waste fed to the water often ends up in the bodies of marine animals, so they can return to us as food. Thermal water pollution also has multiple effects on the changes in the wildlife composition of aquatic ecosystems. Polluted water can be purified by

    1984-01-01

    In the early 1970's, National Space Technology Laboratories discovered that water hyacinths literally thrive on sewage; they absorb and digest nutrients and minerals from wastewater, converting sewage effluents to clean water. They offer a means of purifying water at a fraction of the cost of a conventional sewage treatment plant, and provide a bonus value in byproducts. Hyacinths must be harvested at intervals; the harvested plants are used as fertilizers, high-protein animal feed and a source of energy. Already serving a number of small towns, the "aquaculture" technique has significantly advanced with its adoption by a major U.S. city.

    Full Text Available The present study endeavors to investigate the impact of visual and etymological treatments on learning idioms among English language learners. Seventy-nine intermediate students at Rooz Academy Language School in Babol were selected from among a total number of 116 learners based on their performances on the Longman complete course for the TOEFL test to fulfill the purpose of the study. The students were then assigned into three experimental groups. Initially, a pre-test of idiomatic expressions including 48 idiomatic items was administered to the participants in all groups. During the instructional period, the groups were taught a group of abnormally decomposable idioms through different treatments, namely, visual, etymological, and a combination of visual-etymological elaboration. At the end of the instructional period, the participants in all groups were given a posttest which was the same as the pretest. The design of this study is quasi-experimental. The data obtained was analyzed using one-way ANOVA analysis. The results of data analysis revealed that the etymological treatment was more effective than visual aids on learning idioms among intermediate English language learners. However, the visual-etymological treatment was the most effective one. The findings of this study have implications for EFL teachers, students, and materials developers.

    The state of Sabah contributes one third of the tuberculosis (TB) cases in Malaysia. To collect information on factors that affect the time period from the onset of symptoms to first contact with health care providers, whether private or government. A cross-sectional study using a pre-tested questionnaire was conducted among 296 newly registered smear-positive TB patients in 10 districts in Sabah. Univariable and multivariable analyses were used to determine which risk factors were associated with patient delay (>30 days) and 'extreme' patient delay (>90 days). The percentage of patients who sought treatment after 30 and 90 days was respectively 51.8% (95%CI 45.7-57.9) and 23.5% (95%CI 18.6-29.0). The strongest factors associated with patient delay and 'extreme' patient delay was when the first choice for treatment was a non-government health facility and in 30-39-year-olds. 'Extreme' patient delay was also weakly associated, among other factors, with comorbidity and livestock ownership. Delay and extreme delay in seeking treatment were more common when the usual first treatment choice was a non-government health facility. Continuous health education on TB aimed at raising awareness and correcting misconceptions is needed, particularly among those who use non-government facilities.

    Full Text Available Background: Despite undeniable evidence for the efficacy and effectiveness of Cognitive Behaviour Therapy for Insomnia (CBT-I, the potential for its widespread dissemination and implementation has yet to be realised. A suggested reason for this is that traditional CBT-I is considered too burdensome for deployment, in its current form, within the context of where it would be most beneficial—Primary Care. One strategy, aimed to address this, has been to develop briefer versions of CBT-I, whilst another has been to deliver CBT-I in a group format. An alternative has been to attempt to address insomnia during its acute phase with a view to circumventing its progression to chronic insomnia. The aim of the present study was to compare a brief version of CBT-I (one-shot when delivered individually or in groups to those with acute insomnia. Method: Twenty-eight individuals with acute insomnia (i.e., meeting full DSM-5 criteria for insomnia disorder for less than three months self-assigned to either a group or individual treatment arm. Treatment consisted of a single one-hour session accompanied by a self-help pamphlet. Subjects completed measures of insomnia severity, anxiety and depression pre-treatment and at one-month post-treatment. Additionally, daily sleep diaries were compared between pre-treatment and at the one-month follow up. Results: There were no significant between group differences in treatment outcome on any sleep or mood measures although those in the group treatment arm were less adherent than those who received individual treatment. Furthermore, the combined (group and individual treatment arms pre-post test effect size on insomnia symptoms, using the Insomnia Severity Index, was large (d = 2.27. Discussion: It appears that group treatment is as efficacious as individual treatment within the context of a “one shot” intervention for individuals with acute insomnia. The results are discussed with a view to integrating one-shot CBT

    This study examined the effects of GeoGebra on mathematics performance of students with different spatial visualization. A qusai-experimental, pretest-posttest control group design was conducted. A total of 71 students from two intact groups were involved in the study. They were in two groups and each group was randonly assigned to the experimental group (36 students) and control group (35 students). A spatial visual test to identify students with high or low visualization, and a mathematics performance pre-test were administered at the initial stage of this study. A post-test was administered after 12 weeks of treatment using GeoGebra. Analyses of Covarion (ANCOVA) was used to adjust for the pre-test score. Findings showed that the group with access to GeoGebra achieved significantly better test scores in the posttest as compared to the group which followed the traditional teaching method. A two-way ANCOVA used to analyse the effect of students' spatial visualization on post-test performance showed that there was no effect. The results from this study suggested that using GeoGebra had helped the students to score better in the posttest. However, there is no significance difference on mathematics performances on students with difference types of spatial visualisastion. This study indicates that GeoGebra is useful in enhancing the teaching and learning of mathematics.

    Approximately 60 % of all cancer patients receive radiotherapy as a component of their treatment. Radiation Oncology concepts, specifically, are not formally introduced to students in most traditional school curricula until their clinical rotations or may only be included as an optional elective during the core clinical clerkships. The aim of this study is to determine whether the teaching of Radiation Oncology by radiation oncologists, in the third year, in block diagnostic and therapeutic procedures, is helpful for student training and changes their attitude towards the specialty. We administered a pre-test and post-test examination of the concepts in general radiation oncology, radiation physics, radiobiology, breast cancer and their opinion to the third year medical students. The 10-question, multiple choice tests were administered before starting the lessons and when they finished the course. Of the 130 third year students, 95 (73.07 %) participated in the pre-test and post-test analysis. For the entire cohort, improvement was seen in all questions except one regarding physics. A statistically significant improvement (p < 0.005) was seen in the question regarding the aspects of general radiotherapy, radiobiology, acute and after-effects of radiation and the management of early-stage breast cancer. With an adequate methodology, third year students can learn aspects of Radiation Oncology.

    This pilot experimental study tested the feasibility and intended effect of an educational intervention for parents to help them assist their adolescent child with chronic illness (CI) in becoming autonomous. A two-phase pre-post pilot intervention study targeting parents of adolescents with CI was conducted. Parents were allocated to group 1 and 2 and received the four-module intervention consecutively. Intended effect was measured through online questionnaires for parents and adolescents before, at 2 months after, and at 4-6 months after the intervention. Feasibility was assessed through an evaluation questionnaire for parents. The most useful considered modules concerned the future of the adolescent and parents and social life. The most valued aspect was to exchange with other parents going through similar problems and receiving a new outlook on their relationship with their child. For parents, improvement trends appeared for shared management, parent protection, and self-efficacy, and worsening trends appeared for coping skills, parental perception of child vulnerability, and parental stress. For adolescents, improvement trends appeared for self-efficacy and parental bonding and worsening trends appeared for shared management and coping skills. Parents could benefit from peer-to-peer support and education as they support the needed autonomy development of their child. Future studies should test an online platform for parents to find peer support at all times and places.

  13. Solar Alpha Rotary Joint (SARJ) Lubrication Interval Test and Evaluation (LITE). Post-Test Grease Analysis

    Golden, Johnny L.; Martinez, James E.; Devivar, Rodrigo V.

    2015-01-01

    The Solar Alpha Rotary Joint (SARJ) is a mechanism of the International Space Station (ISS) that orients the solar power generating arrays toward the sun as the ISS orbits our planet. The orientation with the sun must be maintained to fully charge the ISS batteries and maintain all the other ISS electrical systems operating properly. In 2007, just a few months after full deployment, the starboard SARJ developed anomalies that warranted a full investigation including ISS Extravehicular Activity (EVA). The EVA uncovered unexpected debris that was due to degradation of a nitride layer on the SARJ bearing race. ISS personnel identified the failure root-cause and applied an aerospace grease to lubricate the area associated with the anomaly. The corrective action allowed the starboard SARJ to continue operating within the specified engineering parameters. The SARJ LITE (Lubrication Interval Test and Evaluation) program was initiated by NASA, Lockheed Martin, and Boeing to simulate the operation of the ISS SARJ for an extended time. The hardware was designed to test and evaluate the exact material components used aboard the ISS SARJ, but in a controlled area where engineers could continuously monitor the performance. After running the SARJ LITE test for an equivalent of 36+ years of continuous use, the test was opened to evaluate the metallography and lubrication. We have sampled the SARJ LITE rollers and plate to fully assess the grease used for lubrication. Chemical and thermal analysis of these samples has generated information that has allowed us to assess the location, migration, and current condition of the grease. The collective information will be key toward understanding and circumventing any performance deviations involving the ISS SARJ in the years to come.

    The main damaging factors which impact the ITER divertor components are neutron irradiation, cyclic surface heat loads and hydrogen environment. One of the important questions in divertor mockups development is the reliability of beryllium/copper joints and the beryllium resistance under neutron irradiation and thermal cycling. This work presents the experiment, where neutron irradiation and thermocyclic heat loads were applied simultaneously for two beryllium/copper divertor mockups in a nuclear reactor channel to simulate divertor operational conditions. Two mockups with different beryllium grades were mounted facing each other with the tantalum heater placed between them. This device was installed in the active zone of the nuclear reactor SM-2 (Dimitrovgrad, Russia) and the tantalum block was heated by neutron irradiation up to a high temperature. The main part of the heat flux from the tantalum surface was transported to the beryllium surface through hydrogen, as a result the heat flux loaded two mockups simultaneously. The mockups were cooled by reactor water. The device was lowered to the active zone so as to obtain the heating regime and to provide cooling lifted. This experiment was performed under the following conditions: tantalum heater temperature - 1950degC; hydrogen environment -1000 Pa; surface heat flux density -3.2 MW/m{sup 2}; number of thermal cycles (lowering and lifting) -101; load time in each cycle - 200-5000 s; dwell time (no heat flux, no neutrons) - 300-2000 s; cooling water parameters: v - 1 m/s, Tin - 50degC, Pin - 5 MPa; neutron fluence -2.5 x 10{sup 20} cm{sup -2} ({approx}8 years of ITER divertor operation from the start up). The metallographic analysis was performed after experiment to investigate the beryllium and beryllium/copper joint structures, the results are presented in the paper. (author)

    1986-06-01

    After the Spent Fuel Test - Climax (SFT-C) was completed, additional calculations were performed using the best available (directly measured or inferred from measurements made during the test) input parameters, thermal properties, and power levels. This report documents those calculations and compares the results with measurements made during the three-year heating phase and six-month posttest cooling phase of the SFT-C. Three basic types of heat-transfer calculations include a combined two-dimensional/three-dimensional, infinite-length, finite-difference model; a fully three-dimensional, finite-length, finite-difference model; and a fully three-dimensional, finite-length, analytical solution. The finite-length model much more accurately reflects heat flow near the ends of the array and produces cooler temperatures everywhere than does its infinite-length counterpart. 14 refs., 144 figs., 4 tabs

    SLSF experiment W-1 was designed to investigate fuel pin-to-coolant heat transfer during various LMFBR flow-coastdown events in the burnup interval from 0.0 atom percent to 0.5 atom percent. In the study reported here, data from in-fuel thermocouples and coolant (wire-wrap) thermocouples were evaluated during steady-state and transient operation from the beginning of the experiment through LOPI-4 (Loss-of-Piping-Integrity Transient Number 4). The objective of the data evaluation was to determine how maximum coolant temperatures during successive LOPI transients were affected by burnup. A second objective was to identify the mechanisms responsible for this burnup effect

    The model bundle of WWER-type were tested under SFD condition in the out-of-pile CORA installation. The objective of the test was to provide an information on the WWER-type fuel bundles behaviour under severe fuel damage accident conditions. Also it was assumed to compare the WWER-type bundle damage mechanisms with these experienced in the PWR-type bundle tests with aim to confirm a possibility to use the various code systems, worked our for PWR as applied to WWER. In order to ensure the possibility of the comparison of the calculated core degradation parameters with the real state of the tested bundle, some parameters have been measured on the bundle cross-sections under examination. Quantitative parameters of the bundle degradation have been evaluated by digital image processing of the bundle cross-sections. The obtained results are shown together with corresponding results obtained by the other participants of this investigation. (author). 3 refs, 13 figs

    1975-01-01

    Postflight test analysis data processing techniques for shuttle approach and landing tests (ALT) navigation data are defined. Postfight test processor requirements are described along with operational and design requirements, data input requirements, and software test requirements. The postflight test data processing is described based on the natural test sequence: quick-look analysis, postflight navigation processing, and error isolation processing. Emphasis is placed on the tradeoffs that must remain open and subject to analysis until final definition is achieved in the shuttle data processing system and the overall ALT plan. A development plan for the implementation of the ALT postflight test navigation data processing system is presented. Conclusions are presented.

    Thermal and structural responses of the reactor coolant piping under elevated temperature and pressure conditions are being investigated in piping failure tests in WIND (Wide Range Piping Integrity Demonstration) project at JAERI (Japan Atomic Energy Research Institute). The elasto-plastic creep analysis was performed with ABAQUS code for the test using a nuclear grade type 316 stainless steel pipe, which had an outer diameter of 114.3 mm and a wall thickness of 13.5 mm. The major material properties at elevated temperature needed for the analysis were measured for specimen sectioned from the test pipe. Based on the measured creep data, a creep constitutive equation including the tertiary stage was developed and incorporated into ABAQUS code. We compared the results of the three-dimensional analysis with those of two-dimensional analysis and the piping failure test. The comparison showed that the piping failure timing and deformation of pipe obtained from the three dimensional analysis underestimated the test results, and that temperature history at the elevated temperature should be adequately considered.

    Highlights: • TRACE modelization for PKL and ROSA/LSTF installations. • Secondary-side depressurization as accident management action. • CET vs PCT relation. • Analysis of differences in the vessel models. - Abstract: Experimental facilities are scaled models of commercial nuclear power plants, and are of great importance to improve nuclear power plants safety. Thus, the results obtained in the experiments undertaken in such facilities are essential to develop and improve the models implemented in the thermal-hydraulic codes, which are used in safety analysis. The experiments and inter-comparisons of the simulated results are usually performed in the frame of international programmes in which different groups of several countries simulate the behaviour of the plant under the accidental conditions established, using different codes and models. The results obtained are compared and studied to improve the knowledge on codes performance and nuclear safety. Thus, the Nuclear Energy Agency (NEA), in the nuclear safety work area, auspices several programmes which involve experiments in different experimental facilities. Among the experiments proposed in NEA programmes, one on them consisted of performing a counterpart test between ROSA/LSTF and PKL facilities, with the main objective of determining the effectiveness of late accident management actions in a small break loss of coolant accident (SBLOCA). This study was proposed as a result of the conclusion obtained by the NEA Working Group on the Analysis and Management of Accidents, which analyzed different installations and observed differences in the measurements of core exit temperature (CET) and maximum peak cladding temperature (PCT). In particular, the transient consists of a small break loss of coolant accident (SBLOCA) in a hot leg with additional failure of safety systems but with accident management measures (AM), consisting of a fast secondary-side depressurization, activated by the CET. The paper presents the results obtained in the simulations for both installations using TRACE, observing, in general, a good agreement with the experiments. However, ROSA/LSTF calculations underestimated the maximum PCT value, what might be explained by the higher core level predicted in the simulation compared with the experiment. In PKL calculations, PCT maximum value is slightly higher than in the experiment, and the core level predicted is lower. In the comparison of the evolution of both installations a different timing in the transient events is observed, due to the difference in the pressure vessel design. Thus, when PKL vessel is modified with some of the ROSA/LSTF features, the evolution of the new PKL model behaviour is closer the one observed in ROSA/LSTF calculations.

    To evaluate the influence of heat treatment (HT) procedures of a pre-hydrolyzed silane on bond strength of resin cement to a feldspathic ceramic. Ceramic and composite blocks (N = 30) were divided into six groups (n = 5) and subjected to the following conditioning procedures: G1: 9.6% hydrofluoric acid (HF) for 20 s + silane (RelyX Ceramic Primer, 3M ESPE) + resin cement (Panavia F2.0, Kuraray) (control); G2: HF (20 s) + silane + heat treatment in furnace (HTF) (100°C, 2 min) + resin cement; G3: silane + HTF + resin cement; G4- HF (20 s) + silane + heat treatment with hot air (HTA) (50 ± 5°C for 1 min) + resin cement; G5: silane + HTA + resin cement; G6: silane + resin cement. The microtensile bond strength (MTBS) test was performed using a universal testing machine (1 mm/min). After debonding, the substrate and adherent surfaces were analyzed using a stereomicroscope and SEM to categorize the failure types. The data were statistically evaluated using one-way ANOVA and Tukey's test (5%). The control group (G1) showed no pre-test failures and presented significantly higher mean MTBS (16.01 ± 1.12 MPa) than did other groups (2.63 ± 1.05 to 12.55 ± 1.52 MPa) (p = 0.0001). In the groups where HF was not used, HTF (G3: 12.55 ± 1.52 MPa) showed significantly higher MTBS than did HTA (G5: 2.63 ± 1.05 MPa) (p silane either in a furnace or with the application of hot air cannot replace the use of HF gel for the adhesion of resin cement to feldspathic ceramic. Yet when mean bond strengths and incidence of pre-test failures are considered, furnace heat treatment delivered the second best results after the control group, being considerably better than hot air application.

    Background Patient compliance is a key factor in treatment success. Satisfied patients are more likely to utilize health services, comply with medical treatment, and continue with the health care providers. Yet, the national tuberculosis control program failed to address some of these aspects in order to achieve the national targets. Hence, this study attempted to investigate patient satisfaction and adherence to tuberculosis treatment in Sidama zone of south Ethiopia. Methods A facility based cross sectional study was conducted using quantitative method of data collection from March to April 2011. A sample of 531 respondents on anti TB treatment from 11 health centers and 1 hospital were included in the study. The sample size to each facility was allocated using probability proportional to size allocation, and study participants for the interview were selected by systematic random sampling. A Pre tested, interviewer administered questionnaire was used to collect the data. Collected data was edited, coded and entered to Epi data version 3.1 and exported to SPSS version 16. Confirmatory factor analysis was done to identify factors that explain most of the variance observed in most of the manifested variables. Bivariate and Multivariate analysis were computed to analyze the data. Result The study revealed 90% of the study participants were satisfied with TB treatment service. However, 26% of respondents had poor adherence to their TB treatment. Patient perceived on professional care, time spent with health care provider, accessibility, technical competency, convenience (cleanliness) and consultation and relational empathy were independent predictors of overall patient satisfaction (P patient satisfaction (Beta = 0.262). In multivariate analysis occupational status, area of residence, perceived time spent with health care provider, perceived accessibility, perceived waiting time, perceived professional care and over all patient satisfaction were significantly

    This study comprehensively examined the effects of treatment interventions for Internet addiction among adolescents in South Korea through a meta-analysis. We analyzed 70 domestic master's theses and journal articles that reported on controlled studies and involved pre- and post-test analyses in the design. The dates of these publications fall between 2000 and 2015. The total effect size, calculated by random-effect analysis (g), revealed that interventions for the treatment of Internet addiction were effective (ES = 1.838). Meta-ANOVAs revealed differences between groups based on a theoretical model, intervention group size, and intervention duration. Integrative therapy produced larger effect sizes (ES = 2.794) compared to other treatment models such as cognitive behavioral therapy and reality therapy. Effect sizes for interventions, including nine to 12 people (ES = 2.178), were larger than those of interventions including more or fewer participants. Finally, treatment interventions that lasted 8 or more weeks revealed larger effect sizes (ES = 2.294) compared to shorter interventions. The study findings suggest directions for the development and effective operation of future Internet addiction interventions among Korean adolescents. Increasing the effectiveness of these interventions requires an integrative theoretical model, an intervention group size of nine to 12 participants, and a long-term intervention.

    The purpose of this exploratory study is to examine rates of auxiliary is and are across dialect patterns produced by African American English with specific language impairment (AAE-SLI) children following language treatment. The following research question is asked: Do AAE-SLI children exhibit rates of auxiliary is and are across dialect patterns consistent with previous reports of typically developing children and adult AAE speakers? A pre-/post-test design was used to identify patterns in which auxiliary is and are were produced at significant levels. Individual performance was included to examine variable rates of use across patterns. Group and individual results suggest children used auxiliary is and are in dialect patterns at rates consistent with typically developing child and adult AAE speakers. We conclude that rates of use may contribute to evidence-based guidelines for morphological intervention with AAE-SLI children.

    To study the cost of induced abortions (unsafe abortion) and treatment of the complications of such abortions. Descriptive study was conducted between July, 2008 and December, 2008 in four tertiary care hospitals of Lahore: Sir Ganga Ram Hospital, Lady Wellingdon Hospital, General Hospital and Family Health Hospital of Family Planning Association of Pakistan. One hundred women admitted with complications of induced abortion were interviewed by lady doctors, who were trained to conduct the interviews. The data was collected through a structured pre-designed and pre-tested questionnaire approved by International Planned Parenthood Federation. Based on the information provided by the woman and/or her husband and hospital sources, the average cost of abortion was Rs.1686/-. The cost varied from Rs. 500/- to 7,000/-depending on the city, type of provider and facilities available at the clinic. The average cost of treating the complications was Rs. 4,197/- ranging from Rs. 1600/- to Rs 45,000/-. At the present exchange rate (September, 2009), the cost will be US$ 20/- to 560/-. Wide variation between two extremes was due to the type and extent of complications. Treatment for abortion-related complications consumes a large portion of hospital budgets for obstetrics and gynaecology and results in considerable mortality and morbidity. Due to restrictive laws and high cost of safe abortions, most women faced with an unwanted pregnancy resort to unsafe abortions.

Perception of acceptability of treatments for adolescent idiopathic scoliosis in the general population (social acceptability Results The families support the use of screening (94.8% at school, immediate bracing (76.4% for scoliosis with a 60% risk of progression, but also therapeutic exercises (86.9% in cases with a 25% risk of progression. Conclusion There is a growing tendency to consider not only the efficacy, effectiveness and efficiency of treatments, but also their acceptability. This patient-centred aspect is especially more important in areas (like adolescent idiopathic scoliosis in which there is some evidence on the efficacy of treatments, but not strong and definitive (RCTs. Adolescent idiopathic scoliosis treatments should thus be carefully considered also in the light of their social acceptability.

    This study investigated the effectiveness of on-campus programming for National Eating Disorder Awareness Week at increasing knowledge of available treatment options and help-seeking intentions for participants with low and high levels of eating concerns. Program attendees were approached as they entered the space reserved for programming and were asked to participate in the study. One hundred thirty-six college students completed the study questionnaire both immediately before attending programming (pre-test) and immediately after attending programming (post-test). Results indicate that after programming both populations reported significantly greater knowledge of on-campus resources and help-seeking intentions for themselves. Only low eating concern participants reported significantly increased help-seeking intentions for a friend. Psychoeducational programming for eating disorders can be effective at increasing access to treatment and encouraging help seeking behaviors for students. Copyright © 2015 Elsevier Ltd.

    Full Text Available There is growing evidence that social and emotional skills can be taught to students in school and teaching these skills can have a positive effect on later outcomes, such as better mental health and less drug use. This paper presents a benefit-cost analysis of a longitudinal social and emotional learning intervention in Sweden, using data for 663 students participating in the evaluation. Intervention costs are compared against treatment impact on self-reported drug use. Pre-test and post-test data are available. Since follow-up data for the participants´ drug use as adults is not available, informed projections have been made. Net present monetary values are calculated for the general public and society. The results show that students in the treatment group report decreasing use of drugs over the five year long intervention, the value of which easily outweighs the intervention costs.

    2016-01-01

    The prominence and incidence of intimate partner violence (IPV) with male military veterans vary, but generally there is consensus that screening and intervention does help reduce IPV. Intervention is generally provided in the community via Batterer Intervention Programs. However, at the Department of Veterans Affairs (VA) intervention is provided via the Domestic Relations Clinic. Nationally the VA has limited treatment for male IPV. An aggregate sample (n = 178) of participants was assessed using the Domestic Violence/Abuse Screen to measure covariate pre-test and post-test outcomes, program failure, and recidivism. The treatment approach is psycho-educationally based to meet the challenging and unique needs of the military veteran population. The results contribute to a more comprehensive understanding of IPV and highlight the need for more intervention and prevention approaches.

    This study used eye-tracking technology to investigate students’ visual attention while taking the Force Concept Inventory (FCI) in a web-based interface. Eighty nine university students were randomly selected into a pre-test group and a post-test group. Students took the 30-question FCI on a computer equipped with an eye-tracker. There were seven weeks of instruction between the pre- and post-test data collection. Students’ performance on the FCI improved significantly from pre-test to post-test. Meanwhile, the eye-tracking results reveal that the time students spent on taking the FCI test was not affected by student performance and did not change from pre-test to post-test. Analysis of students’ attention to answer choices shows that on the pre-test students primarily focused on the naïve choices and ignored the expert choices. On the post-test, although students had shifted their primary attention to the expert choices, they still kept a high level of attention to the naïve choices, indicating significant conceptual mixing and competition during problem solving. Outcomes of this study provide new insights on students’ conceptual development in learning physics.

    The anti-retroviral (ARV) treatment programme in Nigeria is delivered through selected teaching and mission hospitals at a free/subsidized rate. The government aims to scale up ARV treatment in the country. However, non-adherence to ARV medication can lead to viral resistance, treatment failure, toxicities and waste of financial resources. This study examined the factors responsible for non-adherence to free/subsidized ARV treatment in south-east Nigeria. The study was cross-sectional and descriptive. Information was collected from 174 patients selected by simple random sampling from the register of all patients who had been on anti-retroviral therapy (ART) for at least 12 months at the beginning of the study period. Patients were identified during their clinic visits. Information on their socio-demographic profile, ARV treatment and determinants of non-adherence to ARV treatment was obtained from those who gave consent, using pre-tested interviewer-administered questionnaires. All patients clearly understood the need to take ARV drugs throughout their lives, and what the costs entailed. They understood the need for periodic testing, the probability that complications would develop, cost of transportation to treatment site and the daily treatment regimen. Seventy-five per cent of respondents were not adhering fully to their drug regimen; the mean number of days that respondents had been off drugs was 3.57 days the preceding month. Reasons for non-adherence included: physical discomfort (side effects); non-availability of drugs at treatment site; forgetting to carry drugs during the day; fear of social rejection; treatment being a reminder of HIV status; and selling of own drugs to those unable to enrol in the projects. Being female, under 35 years, single, and having higher educational status were significantly associated with non-adherence. It is important that policy makers and programme managers address the factors responsible for non-adherence when scaling up

    Full Text Available Background: Positive psychotherapy is one of the new approaches in psychology which is innovated for treating psychological disorders and enhancing positive emotions. The aim of this study is to investigate the effectiveness of the group positive psychotherapy on elevation of life satisfaction and quality of life in infertile women. Materials and Methods: In a randomized trial study, Beck Depression Inventory II (BDI-II and clinical interview were used in a pre-test post-test control group design. After analyzing the result of the questionnaire, 36 infertile women who showed signs of mild to moderate depression were randomly placed into two following groups: control (n=18 and intervention (n=18. Before the treatment, the members of both groups answered BDI-II, Satisfaction With Life Scale (SWLS and 12 item Short Form Health Survey (SF-12. The intervention group received six sessions of group positive psychotherapy, but the treatment of the control group began six weeks after the intervention group. Results: The results showed that the life satisfaction scores of the intervention group were significantly elevated from 22.66 in pre-test to 26.13 in post-test (P<0.001, while this improvement was not significant in the control group (P=0.405. The difference between life satisfaction scores of the intervention and the control groups was also significant (F=8.92, P=0.006. However, no significant change in the quality of life level of the intervention and control groups was observed (P=0.136. Conclusion: Thus it can be deduced from the findings that this treatment method could be introduced as solution to increase the life satisfaction in infertile women, but not as a treatment for elevating their quality of life (Registration Number: IRCT2013042810063N3.

    1993-01-01

    The Bentonite Mat Demonstration Project (BMDP) is a field demonstration study to determine the construction/installation requirements, permeability, and subsidence performance characteristics of a composite barrier. The composite barrier will consist of on-site sandy-clay blanketed by a bentonite mat and a flexible High Density Polyethylene (HDPE) liner (also called flexible membrane liner). Construction of one control test pad and three bentonite test pads are planned. The control test pad will be used to establish baseline data. Underneath the composite clay cap is a four feet thick loose sand layer in which cavities will be created by evacuation of sand. The present work provides a mathematical model for the BMDP. The mathematical model will be used to simulate the mechanical and structural responses of the composite clay cap during the testing processes. Based upon engineering experience and technical references, a set of nominal soil parameters have been selected

    The aim of this study was to assess the effectiveness of a spiritual-hypnosis assisted therapy (SHAT) for treatment of posttraumatic stress disorder (PTSD) in children. All children, age 6-12 years (N=226; 52.7% females), who experienced the terrorist bomb blasts in Bali in 2002, and subsequently were diagnosed with PTSD were studied, through a longitudinal, quasi-experimental (pre-post test), single-blind, randomized control design. Of them, 48 received group SHAT (treatment group), and 178 did not receive any therapy (control group). Statistically significant results showed that SHAT produced a 77.1% improvement rate, at a two-year follow up, compared to 24% in the control group, while at the same time, the mean PTSD symptom score differences were significantly lower in the former group. We conclude that the method of spiritual-hypnosis is highly effective, economic, and easily implemented, and has a potential for therapy of PTSD in other cultures or other catastrophic life-threatening events.

    2017-05-01

    Full Text Available Based on the content standard, junior high school students are hoped to master vocabulary about 1000 words, so they can understand the conversation. But it fact, most of the students in junior high school do not master vocabulary well. So, the teacher should be able to choose a good media to help students to increase their vocabulary. In this case, flash card with picture story is two of media that can be used to transfer vocabulary material for the students.   The objective of this research is to find the significant differences of using flash card with picture story in vocabulary, and to find which medium is more effective to use as media in vocabulary. This research was true experiment design. Pre test and post test were use to collect the data. There are two problems of the study, (1 are there any significant differences between flash card with picture story in vocabulary mastery for the seventh grade students in SMP PGRI 2 Margatiga academic years 2013/2014?, (2 which one is more effective media in vocabulary learning process, is it flash card or picture story at seventh grade of SMP PGRI 2 Margatiga, academic years 2013/2014?. As a source of data, the researcher utilized flash card with picture story to teach vocabulary for the students. The media help students to learn vocabulary easier and more interesting to understand the subject, so their vocabulary would increase.   The result of the research, it was found that the mean score of picture story in pre test is 53,86, in treatment is 81, and in post test 85,33. Meanwhile the mean score of the flash card media in pre test 59,33, in treatment is 73,5, and in post test is 80,66. It means that the student’s vocabulary has increased, and there is significant difference of using picture story and flash card in vocabulary instruction, and picture story was more effective to use in vocabulary instruction.

    Full Text Available Abstract Background To investigate the presence of pathogenic microbes on chiropractic treatment tables in one outpatient teaching clinic. Additional aims were to test inexpensive disinfectants on tables that may kill microbes and suggest infection control measures for chiropractic offices, clinics and classrooms. The aim of the study was to assess the presence of pathogenic microbes on treatment tables in one outpatient teaching clinic and determine a simple behavioral model for infection control including table disinfection and accepted hand washing and sanitizing protocols. Methods 10 treatment tables were selected and sampled for possible microbial flora on face and hand pieces. Samples were cultured on MacConky's agar and mannitol salt agar, labeled and incubated for up to 48 hours. Confirmatory testing of microbes to determine if drug resistant flora were present was performed. Among tables tested, 5 were selected to test disinfectants. One-half of the face piece and 1 hand piece were treated with two different wipes and then post-tested for microbes. Results Pathogenic microbes were present on chiropractic treatment tables including methicillin-resistant Staph aureus. Simple disinfectants neutralized the pathogens. A rudimentary disinfection procedure and infection control measures are suggested based on the findings. Conclusion Pathogenic microbes may be present on chiropractic treatment tables and can be effectively killed with proper disinfecting. Hand washing/sanitizing is an important measure in infection control as is table disinfecting. Rudimentary behavioral changes to improve chiropractic clinic infection control are needed. More comprehensive behavioral models are needed. All teaching clinics and private chiropractic offices should adopt infection control practices including routine table disinfecting and hand sanitizing. Effective measures can be put in place at minimal costs. Accrediting bodies of chiropractic institutions

    There is a growing need for primary care physicians, but only a small percentage of graduating medical students enter careers in primary care. To assess whether a Primary Care Intraclerkship within the Medicine clerkship can significantly improve students' attitudes by analyzing scores on pre- and post-tests. Students on the Medicine clerkship at the University of Massachusetts Medical School participated in full-day 'intraclerkships',to demonstrate the importance of primary care and the management of chronic illness in various primary care settings. Pre-and post-tests containing students' self-reported, five-point Likert agreement scale evaluations to 26 items (measuring perceptions about the roles of primary care physicians in patient care and treatment) were collected before and after each session. Eleven intraclerkships with 383 students were held between June 2010 and June 2013. Responses were analyzed using the GLM Model Estimate. Results from the survey analysis showed significantly more positive attitudes toward primary care in the post-tests compared to the pre-tests. Students who were satisfied with their primary care physicians were significantly more likely to show an improvement in post-test attitudes toward primary care in the areas of physicians improving the quality of patient care, making a difference in overall patient health, finding primary care as an intellectually challenging field, and in needing to collaborate with specialists. Older students were more likely than younger students to show more favorable answers on questions concerning the relative value of primary care vs. specialty care. A curriculum in Primary Care Internal Medicine can provide a framework to positively influence students' attitudes toward the importance of primary care, and potentially to influence career decisions to enter careers in Primary Care Internal Medicine. Ensuring that medical students receive excellent primary care for themselves can also positively influence

    The objective of this study was to identify, document, and weight attributes of a pain medication that are relevant from the perspective of patients with chronic pain. Within the sub-population of patients suffering from "chronic neuropathic pain", three groups were analyzed in depth: patients with neuropathic back pain, patients with painful diabetic polyneuropathy, and patients suffering from pain due to post-herpetic neuralgia. The central question was: "On which features do patients base their assessment of pain medications and which features are most useful in the process of evaluating and selecting possible therapies?" A detailed literature review, focus groups with patients, and face-to-face interviews with widely recognized experts for pain treatment were conducted to identify relevant treatment attributes of a pain medication. A pre-test was conducted to verify the structure of relevant and dominant attributes using factor analyses by evaluating the most frequently mentioned representatives of each factor. The Discrete-Choice Experiment (DCE) used a survey based on self-reported patient data including socio-demographics and specific parameters concerning pain treatment. Furthermore, the neuropathic pain component was determined in all patients based on their scoring in the painDETECT(®) questionnaire. For statistical data analysis of the DCE, a random effect logit model was used and coefficients were presented. A total of 1,324 German patients participated in the survey, of whom 44 % suffered from neuropathic back pain (including mixed pain syndrome), 10 % complained about diabetic polyneuropathy, and 4 % reported pain due to post-herpetic neuralgia. A total of 36 single quality aspects of pain treatment, detected in the qualitative survey, were grouped in 7 dimensions by factor analysis. These 7 dimensions were used as attributes for the DCE. The DCE model resulted in the following ranking of relevant attributes for treatment decision: "no character

    There are three main goals to the treatment of obesity: prevention and treatment of the complications, realistic reduction of excess weight, psychological well-being. Each individual is in a specific clinical situation and interindividual variability is wide so stereotypic therapeutic schemes are of little use. Treatment calls upon physical exercise, dietary counseling, drugs, and exceptionally surgery. Psychological support is an integral part of patient management. Treatment of respiratory complications focuses on preventing thromboembolism and management of sleep apnea syndrome and alveolar hypoventilation.

    The Department of Obstetrics and Gynaecology, College of Medicine, University of Lagos commenced training programmes in the use of manual Vacuum Aspiration (MVA) for the treatment of septic abortion in 1989. The courses were evaluated using pre-tests and post-tests, and those of the participants from the first 5 years were analysed. 142 doctors and 72 nurses were trained from teaching hospitals, parastatal and private hospitals. The results of 154 participants (71%) were recovered and analysed. The training courses significantly increased the medical knowledge of both doctors and nurses; those from the Teaching Hospitals appearing to gain more. The amount of knowledge gained by those from the private sector, although showing a statistically significant increase was much less than the other participants. More emphasis should be placed on improving the performance of those from the private sector.

    Full Text Available Recent research into difficulties in figurative language in children with ASD highlighted that it is possible to devise training interventions to overcome these difficulties by teaching specific strategies. This study describes how children with ASD can improve their capability to explain metaphors with a treatment. Two types of metaphors, in the “X is Y” form, were addressed: sensory and physico-psychological. To face the difficulties posed by these metaphors, the adult taught two strategies: inserting the connective “is like” between “X” and “Y”, which transforms the metaphor into a simile; comparing “X” and “Y” by means of thinking maps. Two tests of metaphor comprehension were used, one based on sensory and the other on physico-psychological metaphors. Sixteen 10 year-old children participated into the study, including an experimental group formed by 8 children with ASD (n = 4 which had received the treatment, and a control group (n = 4 which had not, and 8 typically-developing (TD children. At the post-test, the experimental group significantly outperformed the controls in explaining both types of metaphors, but only in the sensory metaphors did their performances reach TD children’s levels. These results illuminate how clinical treatment can positively influence the developmental trajectories of metaphor comprehension.

    Approximately 200,000 women are diagnosed with breast cancer in the U.S. every year. These patients commonly suffer from oral complications of their cancer therapy. The purpose of this study was to assess dental hygienists' knowledge and professional practice related to providing care for breast cancer patients. A pre-tested 43-item survey was mailed to a random sample of 10% of all licensed dental hygienists in the state of Michigan (n=962). The survey assessed the respondents' knowledge of potential oral complications of breast cancer treatments as well as their professional practices when treating patients with breast cancer. After 2 mailings, the response rate was 37% (n=331). Descriptive and inferential analyses were conducted using SAS. Many dental hygienists were unaware of the recommended clinical guidelines for treating breast cancer patients and lacked specific knowledge concerning the commonly prescribed anti-estrogen medications for pre-and postmenopausal breast cancer patients. Over 70% of the respondents indicated they were unfamiliar with the AI class of medications. Only 13% of dental hygienists correctly identified the mechanism of action of anti-estrogen therapy. Dental hygienists reported increased gingival inflammation, gingival bleeding, periodontal pocketing, xerostomia and burning tissues in patients receiving anti-estrogen therapies. Less than 10% believed that their knowledge of breast cancer treatments and the potential oral side effects is up to date. Results indicate a need for more education about the oral effects of breast cancer therapies and about providing the best possible care for patients undergoing breast cancer treatment.

    Malaria case management remains a vital component of malaria control strategies. Despite the introduction of national malaria treatment guidelines and scale-up of malaria control interventions in Nigeria, anecdotal evidence shows some deviations from the guidelines in malaria case management. This study assessed factors influencing adherence to malaria diagnosis and treatment guidelines among healthcare workers in public and private sectors in Ogun State, Nigeria. A comparative cross-sectional study was carried out among 432 (216 public and 216 private) healthcare workers selected from nine Local Government Areas using a multistage sampling technique. A pre-tested interviewer administered questionnaire was used to collect information on availability and use of malaria Rapid Diagnostic Test (mRDT) and artemisinin combination therapy (ACT), for management of uncomplicated malaria. Adherence was defined as when choice of antimalarials for parasitological confirmed malaria cases was restricted to recommended antimalarial medicines. Association between adherence and independent variables were tested using Chi-square at 5 % level of significance. Malaria RDT was available in 81.9 % of the public health facilities and 19.4 % of the private health facilities (p = 0.001). Its use was higher among public healthcare workers (85.2 %) compared to 32.9 % in private facilities (p = 0.000). Presumptive diagnosis of malaria was higher among private healthcare workers (94.9 %) compared to 22.7 % public facilities (p = malaria diagnosis and treatment guidelines. Interventions to improve private sector engagement in implementation of the guidelines, training and supply of recommended antimalarial medicines should be intensified.

    This study investigated the efficacy of an Internet-based self-help program with minimal therapist contact via e-mail for Swedish university students with social phobia and public speaking fears. The main objective was to test if the Internet-based self-help program would be more effective if five live group exposure sessions were added. Thirty-eight students meeting the diagnostic and statistical manual of mental disorders, 4th edition criteria for social phobia were randomized into two different treatment groups: Internet delivered cognitive behavior therapy combined with five group exposure sessions (ICBT+ exp) or the Internet program alone (ICBT). Results were analyzed on an intention-to-treat basis. Both treatment groups showed significant improvement from pre- to post-test, and from pre-test to 1-year follow-up, on all measured dimensions (social anxiety, general anxiety, depression levels, and quality of life). For both the groups, the average within-group effect sizes for the primary social anxiety scales, expressed as Cohen's d, were comparable to those seen in traditionally administered cognitive behavioral therapy both at post-test and at 1- year follow-up. The results suggest that the Internet-based self-help program on its own is efficient in the treatment of university students with social phobia. Adding group exposure sessions did not improve the outcome significantly. Copyright 2008 Wiley-Liss, Inc.

    The aim of this study was to investigate in members of the Chinese community in Melbourne the impact of Mental Health First Aid (MHFA) training on knowledge about mental disorders and on attitudes to people with mental illness. The hypotheses were that at the end of the training participants would have increased knowledge of mental disorders and related treatments, and decreased negative attitudes towards people with mental disorders. Respondents were 108 participants of three MHFA training workshops for the Chinese community in Melbourne conducted by a qualified MHFA trainer. Participants completed the research questionnaire prior to the commencement of the training (pre-test) and at its completion (post-test). The questionnaires assessed participants' ability to recognize a mental disorder (depression and schizophrenia) described in the vignettes, knowledge about the professional help and treatment, and negative attitudes towards people with mental illness. Between pre- and post-test there was significant improvement in the recognition of mental disorders, beliefs about treatment became more concordant with health professionals, and negative attitudes reduced. The MHFA training course for general members of the Chinese community in Melbourne produced significant positive change in the level of mental health literacy and reductions in stigmatizing attitudes. The evidence from this study, together with the accumulated evidence of the benefits of MHFA training in the general Australian community, suggests that this approach should be scaled up to a level where it can have an impact on the whole of the Chinese community in Australia.

    Objective To determine if variations in common treatments for benign paroxysmal positional vertigo (BPPV) affected efficacy. Study Design Prospective, pseudo-randomized study. Setting Out-patient practice in a tertiary care facility Subjects and Methods Patients (n=118) with unilateral BPPV of the posterior canal, including 13 patients with BPPV of the lateral canal were tested at a tertiary care center on one of five interventions: canalith repositioning maneuver (CRP), CRP plus home exercise, modified CRP, CRP for patients with involvement of two semicircular canals, self-CRP home exercise. Self-CRP was also compared to previously published data on efficacy of the Brandt Daroff exercise. Main outcome measures were vertigo intensity and frequency, presence/ absence of Dix-Hallpike responses, Vestibular Disorders Activities of Daily Living Scale (VADL), computerized dynamic posturography. Results Vertigo intensity and frequency and Dix-Hallpike responses decreased significantly and posturography and VADL improved significantly from pre- to post tests. No other significant changes were found. The groups did not differ significantly. Vertigo intensity and frequency were not strongly related at pre-test but were related at post-test. Length of illness and age did not influence the results. Conclusions However the head is moved, as long as it is moved rapidly enough and through the correct planes in space repositioning treatments are likely to be effective. Therefore clinicians have a range of choices in selecting the treatment best suited for each patient’s unique needs. PMID:20723779

    Full Text Available Abstract Introduction Among the treatment modalities in this disease , the surgical and conservative means stand out through therapy resources such as electro-thermotherapy and kinetic therapy. The general objective of this study was to evaluate the effects from two protocols of physical therapy in elder women with knee osteoarthritis. Methods An experimental clinical trial type study consisting of pre and post tests was performed, in which 30 female patients were selected, all between 61 and 80 years old, diagnosed with primary knee OA, treated at the Center for Comprehensive Health Care for the Elder (CAISI - Centro de Atenção Integral à Saúde do Idoso. They were divided into 2 groups of 15 persons for each type of treatment: Group I was treated with kinetic therapy, and group II was treated with electro-thermotherapy. Patients from both groups underwent 36 physical therapy sessions during 12 weeks. For data collection, protocol sheets with socio-demographic data, Body Mass Index (BMI at kg/m2, visual analogue scale (VAS and measurement of motion range (ADM were used. For statistics analysis, the Mann-Whitney, Wilcoxon and Chi-square's non-parametric tests were used. Student's parametric tests were also applied as independent samples. Results The tests performed in both groups contributed to the reduction in the level of pain. There were differences in group I and II on the increase of ADM, except in bending the left knee in group II. Conclusion It was concluded that both treatment modalities showed effective therapeutic responses, but these benefits were even higher in OA treatment by kinetic therapy.

    Full Text Available The study aimed to investigate the influence of the cross-linguistic variation on the construction of boundarycrossing motion events in the translation production of the Turkish speakers of L2 English and to measure the impact of explicit instruction and metalinguistic awareness on the learners’ understanding of typological differences and hence their development of L2 ways of expressing motion events. To this aim, the study followed a pre-test post-test quasi-experimental research design, involving a treatment and a control group. A total of 46 second-year university students participated in the study. They were all majoring in English at the English Language Teaching Department, at a state university in Turkey. The control (18 females and 5 males and the treatment group (14 females and 9 males received a two-week instructional treatment, the first group receiving an implicit instruction, and the second an explicit instruction of the boundary-crossing motion event constructions. Prior to the instructional intervention, a pre-test was administered to the participants. Mann-Whitney U test run on the mean scores obtained from the pre-tests indicated no significant differences between the control and the treatment group, U = 282.5, z = .416, p = .678. Within-group analysis based on post-test results after the termination of the instructional treatment revealed that while the implicit instruction had no effect on learners’ acquisition of motion events, z = 1.842, p = .066., the explicit instruction had a significant effect on L1 Turkish learners’ development of their knowledge of L2-like English patterns in construing motion events. Similarly, between-group analysis revealed that the treatment group (Mdn = 4.00, who received an explicit instruction significantly outperformed the control group (Mdn = 2.00, who received implicit instruction, U = 410.5, z = 3.257, p = .001. The study concluded with the implications of findings for English

    Adolescents with ADHD have planning problems, often affecting school- and social functioning. Evidence-based treatments for adolescents with ADHD are scarce and treatment drop-out rates are substantial. The effectiveness of two new, individual, short-term cognitive behavioral therapies (CBT) was investigated: One with an aim on improving planning skills and one solution-focused treatment (SFT) without such an aim. Motivational Interviewing elements were added to both treatments to enhance treatment compliance. In a multi-center randomized clinical trial, 159 adolescents (12-17 years) with ADHD were randomly assigned to one of both treatments. Pre-, post- and 3-month follow-up data were gathered on five domains: Parent-rated ADHD, planning problems and executive functioning (primary outcomes), neuropsychological measures of planning, comorbid symptoms, general functioning, and teacher measures. Attrition was low in both treatments (5%). Adolescents improved significantly between pre- and post-test with large effect sizes on all domains. Improvements remained stable or continued to improve from post-test to follow-up, also when controlling for medication use. Marginally significant differences were found in favor of the planning-focused treatment: parents and therapists evaluated this treatment more positively than SFT and the planning-focused treatment showed more reduction of parent-rated planning problems. Two new CBTs with integrated motivational components were feasible and attrition was low. ADHD symptoms and co-existing problems of the adolescents improved from pre-test to 3 months after treatment. As the planning-focused treatment was evaluated more positive and had marginal additional beneficial effects to SFT, especially planning-focused CBT seems promising to fill the gap in available treatments for adolescents with ADHD.

    Epileptic encephalopathies represent the most severe epilepsies, with onset in infancy and childhood and seizures continuing in adulthood in most cases. New genetic causes are being identified at a rapid rate. Treatment is challenging and the overall outcome remains poor. Available targeted treatments, based on the precision medicine approach, are currently few. To provide an overview of the treatment of epileptic encephalopathies with known genetic determinants, including established treatment, anecdotal reports of specific treatment, and potential tailored precision medicine strategies. Genes known to be associated to epileptic encephalopathy were selected. Genes where the association was uncertain or with no reports of details on treatment, were not included. Although some of the genes included are associated with multiple epilepsy phenotypes or other organ involvement, we have mainly focused on the epileptic encephalopathies and their antiepileptic treatments. Most epileptic encephalopathies show genotypic and phenotypic heterogeneity. The treatment of seizures is difficult in most cases. The available evidence may provide some guidance for treatment: for example, ACTH seems to be effective in controlling infantile spams in a number of genetic epileptic encephalopathies. There are potentially effective tailored precision medicine strategies available for some of the encephalopathies, and therapies with currently unexplained effectiveness in others. Understanding the effect of the mutation is crucial for targeted treatment. There is a broad range of disease mechanisms underlying epileptic encephalopathies, and this makes the application of targeted treatments challenging. However, there is evidence that tailored treatment could significantly improve epilepsy treatment and prognosis.

    To determine whether general practitioners learned better with task-based learning or problem-oriented lecture in a Continuing Medical Education (CME) set-up. Quasi-experimental study. The Aga Khan University, Karachi campus, from April to June 2012. Fifty-nine physicians were given a choice to opt for either Task-based Learning (TBL) or Problem Oriented Lecture (PBL) in a continuing medical education set-up about headaches. The TBL group had 30 participants divided into 10 small groups, and were assigned case-based tasks. The lecture group had 29 participants. Both groups were given a pre and a post-test. Pre/post assessment was done using one-best MCQs. The reliability coefficient of scores for both the groups was estimated through Cronbach's alpha. An item analysis for difficulty and discriminatory indices was calculated for both the groups. Paired t-test was used to determine the difference between pre- and post-test scores of both groups. Independent t-test was used to compare the impact of the two teaching methods in terms of learning through scores produced by MCQ test. Cronbach's alpha was 0.672 for the lecture group and 0.881 for TBL group. Item analysis for difficulty (p) and discriminatory indexes (d) was obtained for both groups. The results for the lecture group showed pre-test (p) = 42% vs. post-test (p) = 43%; pre- test (d) = 0.60 vs. post-test (d) = 0.40. The TBL group showed pre -test (p) = 48% vs. post-test (p) = 70%; pre-test (d) = 0.69 vs. post-test (d) = 0.73. Lecture group pre-/post-test mean scores were (8.52 ± 2.95 vs. 12.41 ± 2.65; p learning through TBL delivery and calls for further exploration of longitudinal studies in the context of CME.

    Substantial burden of diabetes and hypertension is on rise in India, leading to a twin epidemic. India, being a rural country, has unique problems regarding the treatment compliance which is a serious risk for morbidity and mortality. To assess the compliance to treatment of hypertension and diabetes amongst the diagnosed patients from rural area and to study reasons of non-compliance and knowledge and attitude. Community based, cross sectional, observational study conducted in the rural communities of Tara and Barapada villages of Raigad district of Maharashtra. Survey was conducted covering population of 2115 across 360 families, 250 at Barapada and 110 at Tara. All the cases of diabetes and hypertension diagnosed for more than one year were included. A structured and pre-tested questionnaire was administered including details on demography, medical documentation, treatment details and factors assessing the compliance, knowledge and attitude towards the diseases. When reviewed the treatment adherence pattern based on documentary evidence and interview of the patient, on history of taking medication strictly since the detection illness, it was found that more than 70% of the Diabetics and more than 75% of the Hypertensive have discontinued the treatment in between. The most common reasons of non-compliance is the lack of sufficient motivation for treatment adherence as many mentioned (61.4% diabetics, 55.8% hypertensives) difficulty to remember to take daily medication due to work or forgetfulness. This is followed by lack of money (50%diabetics, 55.8% hypertensives) and living far away from doctor in city (43% diabetics and 46% hypertensives). The study findings are only tip of iceberg and the non-adherence to the treatment of diabetes and hypertension in rural population is at alarmingly high. Illiteracy, lack of faith in treatment and motivation, unawareness and self-neglect as well as financial constraints and lack of specialist care in rural area is playing

    Full Text Available Abstract Background Although ivermectin is distributed free of charge through the African Programme for Onchocerciasis Control (APOC, not all eligible individuals within communities receive the annual treatment. This poses a serious threat to efforts aimed to control onchocerciasis. This study attempts to determine factors associated with compliance to Community Directed Treatment with Ivermectin (CDTI and provides a basis for trying to understand how best to sustain long-term compliance in order to achieve success in the control of onchocerciasis. Methods An unmatched case-control study was conducted in Bebeka coffee plantation southwest Ethiopia. Cases were, compliant i.e., those individuals who had been registered on the relevant treatment registers and had taken all the five annual doses of Ivermectin. Controls were non-compliant, i.e. those individuals who had been recorded in the relevant treatment registers during the first treatment round(2003, and did not take at least two doses of which one being in the last treatment round (2007. Data were collected using a pre-tested interviewer administered structured questionnaire. Data were edited, cleaned, coded and analyzed using SPSS version 12.0.1 for Microsoft Windows. Multiple logistic regression models was used to identify factors associated with compliance to ivermectin. Results From the total of 456 individuals selected for administration of the survey questionnaire, 450(225 cases and 225 controls were contacted and completed the study 2 refused and 4 were unavailable. Five factors associated with compliance were identified: high risk perception [Adjusted Odds Ratio(AOR = 1.98, 95% Confidence Interval (CI, 1.32-2.95], one's family support [AOR = 1.86, 95% CI, 1.22-2.84], perceiving that the Community Drug Distributors (CDDs are doing their work well [AOR = 2.84, 95% CI, 1.50-5.37] and perceiving measuring height is the best way to determine a person's treatment dose [AOR = 6.37, 95% CI, 2

    Full Text Available Many researchers stress the importance of lexical coherence and emphasize the need for teaching collocations at all levels of language proficiency. Thus, this study was conducted to measure the relative effectiveness of explicit (consciousness-raising approach versus implicit (input flood collocation instruction with regard to learners’ knowledge of both lexical and grammatical collocations. Ninety-five upper-intermediate learners, who were randomly assigned to the control and experimental groups, served as the participants of this study. While one of the experimental groups was provided with input flood treatment, the other group received explicit collocation instruction. In contrast, the participants in the control group did not receive any instruction on learning collocations. The results of the study, which were collected through pre-test, immediate post-test and delayed post-test, revealed that although both methods of teaching collocations proved effective, the explicit method of consciousness-raising approach was significantly superior to the implicit method of input flood treatment.

    Background Cancer diagnosis among children can cause high stress and anxiety in parents, and they may lose their life expectancy. The present study investigated the effectiveness of Logo therapy on anxiety and depression among mothers of children with cancer. Materials and Methods This study was conducted by a semi-pilot method using pre-test and post-test with a control experimental group. Therapy sessions were held during 9 sessions of Logo therapy training for 90 minutes. The participants of this study were selected among 30 mothers of children with cancer and using sampling method in Yazd hospitals. The participants divided randomly into two groups: experimental and control. Participants in both experimental and control group completed questionnaires on Beck Anxiety Inventory and Beck Depression Inventory before and after training. Results The results showed that the index of depression and anxiety in control and experimental groups are 32.3, 6.63, 7.4 and 6.75, respectively. So, the level among the experimental group has been decreased after intervention of Logotherapy training and a significant difference occurred in the pre-post test stages. The results showed that Logo Therapy has a significant effect in reducing anxiety and depression among mothers of children with cancer (p<0.05). Conclusion Regarding the efficiency of this approach to reduce anxiety and depression among mothers, this treatment is recommended to be practiced beside other cancer therapies, so they can practice the treatment process with a better mood and mentality.

    2017-09-01

    Although many options are proposed for the treatment of cracked posterior teeth, most treatment decisions are not evidence based. Thus, considerable individual variation can occur regarding treatment recommendations for the same scenario. To our knowledge, there are no studies in the literature assessing practitioners' attitudes toward the treatment of cracked teeth. This research recorded variations between general practitioners and specialist groups regarding the treatment approaches of cracked teeth. In a cross-sectional structured questionnaire survey, 32 prosthodontists, 34 endodontists, and 29 general practitioners working in public and private dental health services in Kuwait were assessed regarding their treatment approach to 5 different clinical cracked tooth scenarios. Chosen treatment options varied greatly. Within each scenario, there was a wide range in treatment preferences across all groups and within each group, especially with respect to asymptomatic cracked teeth. Overall, treatment approaches did not relate to specialty training. Statistically significant differences were noticed between endodontists and general practitioners, in case of crowning teeth, in scenario 3 (P = .032), and in extracting teeth for scenario 5 (P = .048). This study highlights that, despite suggested guidelines, there are large differences in the approach to treatment planning for cracked teeth by practitioners and specialists, both as a whole and within each group. Further multicountry studies involving larger dental populations are needed to determine factors that influence practitioners' treatment choices and/or whether better or more widely accepted guidelines need to be established. More prospective well-controlled clinical case-based research with long-term follow-ups is required. Copyright © 2017 American Association of Endodontists. Published by Elsevier Inc.
