    Johnson, G.; Heikkilae, M.; Melasuo, T.; Spanner, S.

    Realizing the value and potential of PV-power as well as the growing need for increased cooperation and sharing of knowledge in the field of photovoltaics, FINNIDA and UNICEF decided to undertake a study of selected PV-projects. There were two main objectives for the study: To gather, compile, evaluate and share information on the photovoltaic technology appropriate to developing countries, and to promote the interest and competence of Finnish research institutes, consultants and manufacturers in photovoltaic development. For this purpose a joint evaluation of significant, primarily UN-supported projects providing for the basic needs of rural communities was undertaken. The Gambia and Kenya offered a variety of such projects, and were chosen as target countries for the study. The projects were chosen to be both comparable and complimentary. In the Gambia, the main subject was a partially integrated health and telecommunications project, but a long-operating drinking water pumping system was also studied. In Kenya, a health project in the Turkana area was examined, and also a large scale water pumping installation for fish farming. Field visits were made in order to verify and supplement the data gathered through document research and earlier investigations. Individual data gathering sheets for the project form the core of this study and are intended to give the necessary information in an organized and accessible format. The findings could practically be condensed into one sentence: PV-systems work very well, if properly designed and installed, but the resources and requirements of the recipients must be considered to a higher degree.

    Full Text Available Introduction: cardiovascular diseases (CVD are the major component of premature mortality, generate disability and are a relevant source of cost. The growing incidence of CVD is associated with lifestyle and other modifiable risk factors. Prevention and preclinical detection of CVD reduce morbidity and mortality. Type 2 diabetes is associated with a substantially increased risk of cardiovascular disease. Objective: the aim of the study was to evaluate the health economic consequence of medical therapy with atorvastatin for primary prevention of major cardiovascular events in patients with type 2 diabetes in Italy. Materials and method: in order to reach our objective we drew clinical information from the CARDS study. This economic evaluation was carried out conducting a cost/effectiveness analysis from the perspective of National Health Service (NHS. The analysis was applied to a time horizon in conformity with the observational period adopted in the CARDS study (3.9 years. An incremental cost/effectiveness ratio (ICER was calculated and is expressed as cost per life years gained (LYG. In order to test the robustness of the results, a one-way sensitivity analysis was performed. Results: the total cost of atorvastatin therapy over 3.9 years amounts to around 1.5 million of euros per 1,000 patients. The total cost of adding atorvastatin to standard care in people treated for primary prevention of major cardiovascular events in type 2 diabetes as those involved in the CARDS study would entail an additional cost of about 1,2 million of euros per 1,000 patients treated per 3.9 years, with an incremental cost/effectiveness ratio (ICER equivalent to 36,566 euros per patient per LYG. Discussion: the current study is the first economic evaluation of CARDS study to the Italian situation. The results of the current study show that hypolipemic therapy with atorvastatin 10 mg in diabetic individuals is to be considered cost effective.

    In order to achieve more correct diagnosis of gastric lesion, further progress in the technique of diagnosis is much desired. And so, in pursuing the more ideal study, about 7,500 cases of U. G. I. studies taken in Severance Hospital in the past 29 months from May 1969 to September 1971, have been reviewed to evaluate how the following factors will affect the demonstrability of gastric lesion in upper G. I. series. (1) Introduction of air into the stomach by nasogastric tube. (2) Kinds and concentration of barium. (3) Demonstrability according to the position of the patient. (4) Use of antispasmodics. The results may be briefly summarized as follows: 1. The intubation of nasogastric tube gives discomfort temporarily to the patient: however, it has an advantage that the amount of air required for ideal insufflation of the stomach can be controlled under the fluoroscopy. 2. About concentration and type of barium. a) Mikabarium in 90% seems to give the best result in filling study, mucosal relief study and double contrast study. b) Mikabarium in higher concentration adheres to the mucosa better, thus resulting in good double contrast: however, it tends to coagulate each other in the high concentration. c) Micropaque powder of 110% solution produces good double contrast, but it has the disadvantage of making air bubbles. d) When water is given prior to barium ingestion, the anterior wall of stomach is better demonstrated with mucosal relief study. e) To get better result in contrast study, the selection of barium is important as well as rapid and proper positioning of the patient and abdominal respiratory movement. 3. Demonstrability of the stomach lesion according to the position. a) The small lesion either in pylorus or in antrum can be best demonstrated by compression technique of double contrast method in supine position. b) The mucosal relief study in prone by adequate air insufflation was proper to demonstrate the lesion of anterior wall. c) In the lesion of the

    Automated Writing Evaluation (AWE) program is designed to provide instant scores based on automated writing scor⁃ing engine along with diagnostic feedback. Five main AWE programs are introduced, four invented by foreign companies and one by Chinese native company for Chinese students. This paper reviews studies on AWE home and abroad from perspectives of its validity and instructional application. These studies have shown that AWE program should be used as an instructional tool to improve writing skill rather than only as a scoring and feedback engine. So how to implement and integrate AWE program into instructional context and to achieve more desirable learning outcomes while avoiding potential harms should be the focus of study for the future research.

  19. Ground motion input in seismic evaluation studies

    Sewell, R.T.; Wu, S.C.

    1996-07-01

    This report documents research pertaining to conservatism and variability in seismic risk estimates. Specifically, it examines whether or not artificial motions produce unrealistic evaluation demands, i.e., demands significantly inconsistent with those expected from real earthquake motions. To study these issues, two types of artificial motions are considered: (a) motions with smooth response spectra, and (b) motions with realistic variations in spectral amplitude across vibration frequency. For both types of artificial motion, time histories are generated to match target spectral shapes. For comparison, empirical motions representative of those that might result from strong earthquakes in the Eastern U.S. are also considered. The study findings suggest that artificial motions resulting from typical simulation approaches (aimed at matching a given target spectrum) are generally adequate and appropriate in representing the peak-response demands that may be induced in linear structures and equipment responding to real earthquake motions. Also, given similar input Fourier energies at high-frequencies, levels of input Fourier energy at low frequencies observed for artificial motions are substantially similar to those levels noted in real earthquake motions. In addition, the study reveals specific problems resulting from the application of Western U.S. type motions for seismic evaluation of Eastern U.S. nuclear power plants.

    Full Text Available ABSTRACT : Thyroid nodules are common in adults, with a reported prevalence of up to 50%. (1 – 5. Furthermore, 9% to 15% of nodules identified during clinical examinations are diagnosed as malignant (6 – 8. It is gen erally accepted that sonography and sonographically guided fine - needle aspiration cytologic examination are the modalities of choice for differentiating benign and malignant thyroid nodules (1 , 9 . Thyroid ultrasonography (USG is the major diagnostic moda lity for evaluating thyroid nodules. Using USG, a thyroid nodule appears as a nodular lesion within the thyroid gland that is distinguishable from the adjacent parenchyma. Several USG features, such as marked hypoechogenicity, irregular margin, micro calci fications, and a taller - than - wide shape have been introduced as potential predictors for the presence of thyroid malignancies. AIMS & OBJECTIVE : The aim of this study was to assess the accuracy of USG diagnosis for thyroid nodules. MATERIALS & METHODS: Th e present study was conducted in the Department of Radiodiagnosis, TMMC & RC, TMU, Moradabad. Patients under the study were referred from department of Surgery, Paediatrics, Medicine, ENT, Gynaecology and Obstetrics. Patients for the study were evaluated b y Clinical & Radiological examination. The total number of patients were 120. RESULT: On clinical examination, multiple nodules were found only in 17% of cases, whereas on USG, multiple nodules were found in 58%. 50% of clinically solitary nodules were d emonstrated to be multiple on USG. CONCLUSION: In conclusion, similar to the recent literature reviewed so far, for a large majority of patients, diagnosis changed after ultrasonography, so the results necessitate the use of ultrasonography, which is a non invasive method, as a complementary method to physical examination in the diagnosis of thyroid diseases, especially thyroid nodules.

    Full Text Available In Pasteur Institute laboratories there was developed AVISALMVAC, a vaccine against avian Salmonella, a biological product that contains S. enteritidis and S. typhimurium bacterin, with oil adjuvant. This paper presents the results of the studies regarding the stability and toxicity evaluation of this vaccine stored under conditions recommended by the manufacturer (2-80C at the end of the period of validity. The vaccine stability was assessed by serological and histopathological analysis of samples from SPF chickens vaccinated with the product at the end of the period of validity. The study of Avisalmvac toxicity was carried out by inoculation of the product or its components on Vero cell monolayer, and the effects were microscopically recorded or by MTT test, applied at 6 days post-inoculation. Antibody titers recorded at 2 and 3 weeks post vaccination demonstrated the vaccine ability (used after an year since manufacture to induce synthesis of specific antibodies and therefore, the product stability was proven. Histopathological examinations carried out on samples taken at 18 days post vaccinationfrom the vaccination site (skeletal muscle and skin and spleen, did not show any lesions associated to vaccination with Avisalmvac. The cytotoxicity analysis made by inoculating the vaccine or its components on Vero cell monolayer and the microscopic examination did not record visible cytopathic effects for any vaccine dilutions or vaccine components. The cell metabolism evaluation by MTT assay made at 6 days after vaccine/vaccine components inoculation on Vero monolayer, shown the ability of the vaccine and oil adjuvant to stimulate cell metabolism, and a certain degree of toxicity / inhibition of dehydrogenase metabolism associated to one of emulsifier but at dilutions higher than those used in the vaccine formula.

    This feasibility study evaluated the impact of a culturally consistent diabetes educational program, led by a Latino pastor, on Latino community diabetes knowledge levels. Latino adults were recruited from two churches serving Latino populations, one identified as intervention, the other as nonintervention. Both churches received the American Diabetes Association's booklets on diabetes education, "Four Steps to Control Your Diabetes for Life." The intervention group also received weekly reviews of the booklet's information from the church pastor, who was educated about diabetes by a Latino family nurse practitioner. Pre- and postintervention levels of diabetes knowledge were measured using the Diabetes Knowledge Questionnaire. Mean changes in the Diabetes Knowledge Questionnaire (DKQ-24) survey from pretest to posttest indicated a significant increase in knowledge in both groups. Only the grades for the participants from the pastor-led group, however, moved from failure in knowledge to high levels of passing. One hundred percent of intervention group participants reported having read the literature. This pilot study supports the feasibility of a local Latino pastor, as a culturally consistent diabetes educator, to increase Latino parishioner's knowledge of diabetes. © 2015 Society for Public Health Education.

    Full Text Available Purpose: To determine external, middle, and inner ear abnormalities on high-resolution computed tomography (HRCT of temporal bone in patients with microtia and to predict anatomic external and middle ear anomalies as well as the degree of functional hearing impairment based on clinical grades of microtia. Materials and Methods: It was a retrospective study conducted on Indian population. Fifty-two patients with microtia were evaluated for external, middle, and inner ear anomalies on HRCT of temporal bone. Clinical grading of microtia was done based on criteria proposed by Weerda et al. in 37 patients and degree of hearing loss was assessed using pure tone audiometry or brainstem-evoked response in 32 patients. Independent statistical correlations of clinical grades of micotia with both external and middle ear anomalies detected on HRCT and the degree of hearing loss were finally obtained. Results: The external, middle, and inner ear anomalies were present in 93.1%, 74.5%, and 2.7% patients, respectively. Combined cartilaginous and bony external auditory canal atresia (EAC was the most common anatomic abnormality in our group of microtia patients. Hypoplastic mesotympanum represented the commonest middle ear anomaly. The incidence of combined ossicular dysplasia and facial canal anomalies was lower as compared to other population groups; however, we recorded a greater incidence of cholesteatoma. Both these factors can have a substantial impact on outcome of patients planned for surgery. We found no significant association between grades of microtia and external or middle ear anomalies. Similarly, no significant association was found between lower grades of microtia (grade I and II and degree of hearing loss. However, association between grade III microtia and degree of hearing loss was significant. A significant association between congenital cholesteatoma and degree of pneumatization of atretic plate and mastoid process not previously studied

  12. Study on segmented distribution for reliability evaluation

    Directory of Open Access Journals (Sweden)

    Huaiyuan Li

    2017-02-01

    Full Text Available In practice, the failure rate of most equipment exhibits different tendencies at different stages and even its failure rate curve behaves a multimodal trace during its life cycle. As a result, traditionally evaluating the reliability of equipment with a single model may lead to severer errors. However, if lifetime is divided into several different intervals according to the characteristics of its failure rate, piecewise fitting can more accurately approximate the failure rate of equipment. Therefore, in this paper, failure rate is regarded as a piecewise function, and two kinds of segmented distribution are put forward to evaluate reliability. In order to estimate parameters in the segmented reliability function, Bayesian estimation and maximum likelihood estimation (MLE of the segmented distribution are discussed in this paper. Since traditional information criterion is not suitable for the segmented distribution, an improved information criterion is proposed to test and evaluate the segmented reliability model in this paper. After a great deal of testing and verification, the segmented reliability model and its estimation methods presented in this paper are proven more efficient and accurate than the traditional non-segmented single model, especially when the change of the failure rate is time-phased or multimodal. The significant performance of the segmented reliability model in evaluating reliability of proximity sensors of leading-edge flap in civil aircraft indicates that the segmented distribution and its estimation method in this paper could be useful and accurate.

    In western China,the terrain and meteorological conditions are so complex that it is not suitable to construct new radar stations.Automatic dependent surveillance-broadcast(ADS-B) is a totally new surveillance method,so before practically applied and operated in China,abundant tests and evaluations are necessary to validate the performance of ADS-B and guarantee the operational security.During the flight tests,we collect the data of radar,ADS-B and high accuracy position and compare the performance of ADS-B with radar based on high accuracy position.To solve the asynchronous problem among radar data,ADS-B data and real-time kinematic(RTK) data caused by different update rates,this article proposes the technique of synchronizing multi-surveil- lance data by extrapolating from the data of low update rate to high update rate according to velocity and heading.Meanwhile,because radar data,ADS-B data and RTK data are expressed in different coordinates and cannot be compared each other,this article provides a method to unifying the coordinates of multi-surveillance data.By the analysis and evaluation,we can conclude that the performance of ADS-B is better than radar.

We believe the quality models (mostly derived from EFQM excellence model don’t fit very well into non-profit activities, policies and programmes, because they are much more complex than environment, from which quality models derive from (for example assembly line. Quality of an academic study programme is very complex and understood differently by various stakeholders, so we present dimensional evaluation in the article. Dimensional evaluation, as opposed to component and holistic evaluation, is a form of analytical evaluation in which the quality of value of the evaluand is determined by looking at its performance on multiple dimensions of merit or evaluation criteria. First stakeholders of a study programme and their views, expectations and interests are presented, followed by evaluation criteria. They are both joined into the evaluation model revealing which evaluation criteria can and should be evaluated by which stakeholder. Main research questions are posed and research method for each dimension listed.

  20. STUDIES AND EVALUATION OF COMPRESSED MICROSPHERES

    2016-05-01

    Full Text Available This work was aimed at the use of dissolution testing and similarity factor to assess the level of damage taken by active drug microspheres during compression in tablet dosage form. To achieve that, combinations of suitable excipients were used to protect drug microspheres during compression. The excipients were used in the form of powders, granules or placebo pellets prepared by extrusion-spheronization technology. The excipients were evaluated alone, in combinations and post-compression into compacts.  Preliminary experiments included density, hardness, friability and disintegration on all of the selected excipients. Based on such experiments it was found that the flowability of combination powders was more acceptable than individual excipients. Two combinations of microcrystalline -starch and microcrystalline cellulose -calcium carbonate granules were selected to be compressed with active ketoprofen pellets. In all the combinations used there was a significant amount of damage to drug pellets.  The kinetics of drug release appears to follow the zero-order rate and the rate remained unchanged even when a significant degree of damage to pellets occur. It was found that a high level of excipients is required in order to prepare microspheres as a rapid disintegrating tablet.

  2. Bias During the Evaluation of Animal Studies?

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available My recent book entitled The Costs and Benefits of Animal Experiments seeks to answer a key question within animal ethics, namely: is animal experimentation ethically justifiable? Or, more precisely, is it justifiable within the utilitarian cost:benefit framework that fundamentally underpins most regulations governing animal experimentation? To answer this question I reviewed more than 500 scientific publications describing animal studies, animal welfare impacts, and alternative research, toxicity testing and educational methodologies. To minimise bias I focused primarily on large-scale systematic reviews that had examined the human clinical and toxicological utility of animal studies. Despite this, Dr. Susanne Prankel recently reviewed my book in this journal, essentially accusing me of bias. However, she failed to provide any substantive evidence to refute my conclusions, let alone evidence of similar weight to that on which they are based. Those conclusions are, in fact, firmly based on utilitarian ethical reasoning, informed by scientific evidence of considerable strength, and I believe they are robust.

    Simple Summary Animal experimentation evokes strong emotional responses in people on both sides of the debate surrounding its ethical status. However, the true level of its usefulness to society may only be discerned by careful examination of reliable scientific evidence. My recent book, The Costs and Benefits of Animal Experiments, reviewed more than 500 relevant scientific publications. Recently in this journal, however, a reviewer essentially accused me of bias. Yet the conclusions of my book are based on sound reasoning and strong evidence, and no critic has yet provided any substantive evidence to refute them.

  5. Study of the aerodynamic forces evaluation methods

    Directory of Open Access Journals (Sweden)

    Stelian GALETUSE

    2011-06-01

    Full Text Available This paper reviews some of the different formulations of the force exerted on a submerged body by the fluid flowing around it. The study is particularly focused on identifying the most appropriate formulations and their inherent assumptions and experimental conditions that fit the current experimental techniques. Several force formulations are derived using different assumptions such as finite and infinite domain, simple and double connected domains. The aim was to obtain formulations that can benefit from the data gathered through the particle image velocimetry method, more explicitly the velocity field around the body and its derivatives. The equations were afterwards discussed in terms of their exposure to error magnification due to the limitations of the experimental method and recommendations were made for appropriate situations in which different formulations should be used. In conclusion, all different force formulations are valid and can be used with the Particle Image Velocimetry data but the accuracy of each outcome depends on the problem definition. As a future objective, experimental work should be performed and test the different equations for different flow conditions, steady, unsteady, quasi-steady, and also for different domain ranges.

    1999-06-28

    This Determination of Importance Evaluation (DIE) applies to the Subsurface Exploratory Studies Facility (ESF), encompassing the Topopah Spring (TS) Loop from Station 0+00 meters (m) at the North Portal to breakthrough at the South Portal (approximately 78+77 m), the Enhanced Characterization of the Repository Block (ECRB) East-West Cross Drift Starter Tunnel (to approximate ECRB Station 0+26 m), and ancillary test and operation support areas in the TS Loop. This evaluation applies to the construction, operation, and maintenance of these excavations. A more detailed description of these items is provided in Section 6.0. Testing activities are not evaluated in this DIE. Certain construction activities with respect to testing activities are evaluated; but the testing activities themselves are not evaluated. The DIE for ESF Subsurface Testing Activities (BAJ3000000-01717-2200-00011 Rev 01) (CRWMS M&O 1998a) evaluates Subsurface ESF Testing activities. The construction, operation, and maintenance of the TS Loop niches and alcove slot cuts is evaluated herein and is also discussed in CRWMS M&O 1998a. The construction, operation, and maintenance of the Busted Butte subsurface test area in support of the Unsaturated Zone (UZ) Transport Test is evaluated in CRWMS M&O 1998a. Potential test-to-test interference and the waste isolation impacts of testing activities are evaluated in the ESF Subsurface Testing Activities DIE and other applicable evaluation(s) for the Job Package (JP), Test Planning Package (TPP), and/or Field Work Package (FWP). The objectives of this DIE are to determine whether the Subsurface ESF TS Loop and associated excavations, including activities associated with their construction and operation, potentially impact site characterization testing or the waste isolation capabilities of the site. Controls needed to limit any potential impacts are identified. The validity and veracity of the individual tests, including data collection, are the responsibility

    Johanson, Linda S

    Researchers have related participation in study abroad experiences to many positive outcomes for nursing students; however, educators are faced with the task of not only developing meaningful study abroad opportunities but sustaining and improving them as well. Educators can evaluate repeat study abroad programs by comparing experiences, looking for trends, and conjecturing rationales. To illustrate this process, an example of a study abroad opportunity that has been repeated over 11 years is presented. The first six years have been compared to the most recent five years, revealing three categories of change for evaluation and the resulting course improvements.

  16. Post-occupancy evaluation and field studies of thermal comfort

    Energy Technology Data Exchange (ETDEWEB)

    Nicol, F.; Roaf, S.

    2005-08-01

    The similarities and differences are explored in both the aims and the methods between post-occupancy evaluations and field studies of thermal comfort in buildings. The interpretations of the field study results are explored, especially the ways the results differ from laboratory experiments. Particular attention is drawn to the dynamic nature of the interaction between buildings and their occupants. Answers to questions of the type used in post-occupancy evaluations are compared with results from field studies of thermal comfort, and the implications of these findings for the evaluation of buildings and the conduct of post-occupancy evaluation are explored. Field studies of thermal comfort have shown that the way in which occupants evaluate the indoor thermal environment is context-dependent and varies with time. In using occupants as part of the means of measuring buildings, post-occupancy evaluations should be understood as reflecting the changing nature of the relationship between people, the climate and buildings. Surveys are therefore measuring a moving target, and close comparison based on such surveys need to take this in to account. (author)

    Seshadrinathan, Kalpana; Soundararajan, Rajiv; Bovik, Alan C.; Cormack, Lawrence K.

    2010-02-01

    Automatic methods to evaluate the perceptual quality of a digital video sequence have widespread applications wherever the end-user is a human. Several objective video quality assessment (VQA) algorithms exist, whose performance is typically evaluated using the results of a subjective study performed by the video quality experts group (VQEG) in 2000. There is a great need for a free, publicly available subjective study of video quality that embodies state-of-the-art in video processing technology and that is effective in challenging and benchmarking objective VQA algorithms. In this paper, we present a study and a resulting database, known as the LIVE Video Quality Database, where 150 distorted video sequences obtained from 10 different source video content were subjectively evaluated by 38 human observers. Our study includes videos that have been compressed by MPEG-2 and H.264, as well as videos obtained by simulated transmission of H.264 compressed streams through error prone IP and wireless networks. The subjective evaluation was performed using a single stimulus paradigm with hidden reference removal, where the observers were asked to provide their opinion of video quality on a continuous scale. We also present the performance of several freely available objective, full reference (FR) VQA algorithms on the LIVE Video Quality Database. The recent MOtion-based Video Integrity Evaluation (MOVIE) index emerges as the leading objective VQA algorithm in our study, while the performance of the Video Quality Metric (VQM) and the Multi-Scale Structural SIMilarity (MS-SSIM) index is noteworthy. The LIVE Video Quality Database is freely available for download1 and we hope that our study provides researchers with a valuable tool to benchmark and improve the performance of objective VQA algorithms.

    Cost-of-illness (COI) studies aim to assess the economic burden of health problems on the population overall, and they are conducted for an ever widening range of health conditions and geographical settings. While they attract much interest from public health advocates and healthcare policy makers, inconsistencies in the way in which they are conducted and a lack of transparency in reporting have made interpretation difficult, and have ostensibly limited their usefulness. Yet there is surprisingly little in the literature to assist the non-expert in critically evaluating these studies. This article aims to provide non-expert readers with a straightforward guide to understanding and evaluating traditional COI studies. The intention is to equip a general audience with an understanding of the most important issues that influence the validity of a COI study, and the ability to recognize the most common limitations in such work.

    Full Text Available Online study has increasingly become more attractive to students at university level due to convenience access to their instructors and to study resources. This study has developed online social network for study. It proposes to provide lesson content availability, past lecture, by sending online study lesson media to students’ mobile phone or tablet. Approximately 85 undergraduate software engineering students participated for 1.5 semesters. In comparing the use of the study toll, and without the tool, the alterations were found between traditional classroom learning style and online study. Also, the study’s aim was to attest the online study tool’s efficiency. However, these results were not obvious when the achievement factor was controlled by the limitation of time. The primary purpose of this study is to evaluate these two groups of students with extended experiment time for a noticeable result by used questionnaires course examination, and inventory of ILP learning process. The observed, shows that students with online study tools scored higher on course examinations after measures by the mentioned methodology.

    This is an interim report discussing possible guidelines for the assessment and evaluation of projects developing speech and language systems. It was prepared at the request of the European Commission DG XIII by an ad hoc study group, and is now being made available in the form in which it was submitted to the Commission. However, the report is not an official European Commission document, and does not reflect European Commission policy, official or otherwise. After a discussion of terminology, the report focusses on combining user-centred and technology-centred assessment, and on how meaningful comparisons can be made of a variety of systems performing different tasks for different domains. The report outlines the kind of infra-structure that might be required to support comparative assessment and evaluation of heterogenous projects, and also the results of a questionnaire concerning different approaches to evaluation.

  4. Study on Turbulent Modeling in Gas Entrainment Evaluation Method

    Suppression of gas entrainment (GE) phenomena caused by free surface vortices are very important to establish an economically superior design of the sodium-cooled fast reactor in Japan (JSFR). However, due to the non-linearity and/or locality of the GE phenomena, it is not easy to evaluate the occurrences of the GE phenomena accurately. In other words, the onset condition of the GE phenomena in the JSFR is not predicted easily based on scaled-model and/or partial-model experiments. Therefore, the authors are developing a CFD-based evaluation method in which the non-linearity and locality of the GE phenomena can be considered. In the evaluation method, macroscopic vortex parameters, e.g. circulation, are determined by three-dimensional CFD and then, GE-related parameters, e.g. gas core (GC) length, are calculated by using the Burgers vortex model. This procedure is efficient to evaluate the GE phenomena in the JSFR. However, it is well known that the Burgers vortex model tends to overestimate the GC length due to the lack of considerations on some physical mechanisms. Therefore, in this study, the authors develop a turbulent vortex model to evaluate the GE phenomena more accurately. Then, the improved GE evaluation method with the turbulent viscosity model is validated by analyzing the GC lengths observed in a simple experiment. The evaluation results show that the GC lengths analyzed by the improved method are shorter in comparison to the original method, and give better agreement with the experimental data.

    We propose a quantitative evaluation method of skin barrier function using Optical Coherence Microscopy system (OCM system) with coherency of near-infrared light. There are a lot of skin problems such as itching, irritation and so on. It has been recognized skin problems are caused by impairment of skin barrier function, which prevents damage from various external stimuli and loss of water. To evaluate skin barrier function, it is a common strategy that they observe skin surface and ask patients about their skin condition. The methods are subjective judgements and they are influenced by difference of experience of persons. Furthermore, microscopy has been used to observe inner structure of the skin in detail, and in vitro measurements like microscopy requires tissue sampling. On the other hand, it is necessary to assess objectively skin barrier function by quantitative evaluation method. In addition, non-invasive and nondestructive measuring method and examination changes over time are needed. Therefore, in vivo measurements are crucial for evaluating skin barrier function. In this study, we evaluate changes of stratum corneum structure which is important for evaluating skin barrier function by comparing water-penetrated skin with normal skin using a system with coherency of near-infrared light. Proposed method can obtain in vivo 3D images of inner structure of body tissue, which is non-invasive and non-destructive measuring method. We formulate changes of skin ultrastructure after water penetration. Finally, we evaluate the limit of performance of the OCM system in this work in order to discuss how to improve the OCM system.

    The aim of this study was to present a clear process of synthesizing test accuracy data when conducting economic evaluations of diagnostic tests for health technology assessment (HTA) assessors and health economists. We appraised the methods advocated for using diagnostic test accuracy data in economic evaluations. We used a case study of fetal anemia in which data from a screening test are used in combination with a confirmatory test. We developed a step-by-step guide and consider two scenarios: when data on test accuracy from several studies are based on (i) the same test threshold for positivity and (ii) different test thresholds. We conclude that each approach has its strengths and limitations. We show that the optimal operating point of the test should be identified to determine the true cost-effectiveness of the test. We advocate that these issues require a multidisciplinary team of health economists, decision modelers and statisticians.

    In order to make a FBR practicable, it is important to make rational categorization of a safety design evaluation event. In this study, for the purpose of providing useful information into the event categorization, we developed the occurrence frequency data of various abnormal events, presented a proposal of the event categorization primarily based on the occurrence frequency and examined efficiency of the proposal. We researched and analyzed abnormal event instances of foreign and domestic FBR plants and of domestic light water reactor power plants. On the basis of the analysis, the failure occurrence frequency of the protection system (PS) in the FBR model plants with electric power production of 600MW and 1,000MW was quantified. Making use of results of probabilistic safety assessment study, loss-of-function probability of the mitigation system (MS) was quantified. Some of combinations of PS failure and loss of MS function were selected and their occurrence frequencies were quantified. We examined problems in the current categorization of the safety design evaluation event and presented a new proposal of the event categorization. Merits of the new proposal are to have divided the current category of `accident` into `small accident` and `rare accident`, explicitly to treat a multiple failure event not as a collateral analysis condition of supposing `a single failure` but as an event to be evaluated, and to have added a category for the event which is beyond design base, but should be supposed to evaluate depth of the safety design in terms of defense-in-depth. Some candidates of the safety design evaluation event were identified and applied to the new proposal. In comparison with the current categorization, we obtained perspective that it was possible to evaluate the safety design more in detail and effectively, especially depth of the safety design such as backup reactor shutdown system, decay heat removal function in a natural circulation mode etc. (J.P.N.)

    Robotic Minimally Invasive Surgery, and the engendered computer-integration, offers unique opportunities for quantitative computer-based surgical-performance evaluation. In this work, we examine extension of traditional manipulative skill assessment, having deep roots in performance evaluation in manufacturing industries, for applicability to robotic surgical skill evaluation. This method relies on: defining task-level segmentation of modular sub-tasks/micro-motions called 'Therbligs' that can be combined to perform a given task; and analyzing intra- and inter-user performance variance by studying surgeons' performance over each 'Therbligs'. Any of the performance metrics of macro-motions-from motion-economy, tool motion measurements to handed-symmetry-can now be extended over the micro-motion temporal segments. Evaluation studies were based on video recordings of surgical tasks in two settings: first, we examined performance of two representative manipulation exercises (peg board and pick-and-place) on a da Vinci surgical SKILLS simulator. This affords a relatively-controlled and standardized test-scenarios for surgeons with varied experience-levels. Second, task-sequences from real surgical videos were analyzed with a list of predefined 'Therbligs' in order to investigate its overall usefulness.

    2015-10-01

    Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a single measure for evaluating the multiple-item service quality construct based on the SERVQUAL model. A slack-based measure (SBM) of efficiency with constant inputs is used to calculate the PSQI. In addition, a non-linear programming model based on the SBM is proposed to delineate an improvement guideline and improve service quality. An empirical study is conducted to assess the applicability of the method proposed in this study. A large number of studies have used DEA as a benchmarking tool to measure service quality. These models do not propose a coherent performance evaluation construct and consequently fail to deliver improvement guidelines for improving service quality. The DEA models proposed in this study are designed to evaluate and improve service quality within a comprehensive framework and without any dependency on external data.

    The present study aims to evaluate national adaptation planning, using the National Action Plan for Climate Change Adaptation (RAN-API) in Indonesia as a case. In doing so, the current study applies the methodology used in Preston et al. (2011), where a set of 57 adaptation plans from three developed countries was evaluated against 19 planning processes. The same criteria and scoring system were applied to the current study to evaluate RAN-API, both as identified in its document and as viewed by the stakeholders. A desktop review and questionnaires were undertaken to this end. It was found that discrepancies exist between the status of RAN-API as documented and the stakeholders views of some criteria, suggesting that information or knowledge gaps may still exist despite the efforts made for stakeholder engagement. In some of the other criteria, the stakeholders views match the status as identified in the document. Most notably, they both agree that the weakness of RAN-API is related to limited consideration for non-climatic factors. While the development of RAN-API is a critical step taken in the country, the current study finds that there remains room for further improvement. The criteria or indicators to be used to assess the progress of RAN-API as a whole may need to be further elaborated.

    This Air Pollution Control System (APCS) Conceptual Design and Evaluation study was conducted to evaluate a high-performance (APC) system for minimizing air emissions from mixed waste thermal treatment systems. Seven variations of high-performance APCS designs were conceptualized using several design objectives. One of the system designs was selected for detailed process simulation using ASPEN PLUS to determine material and energy balances and evaluate performance. Installed system capital costs were also estimated. Sensitivity studies were conducted to evaluate the incremental cost and benefit of added carbon adsorber beds for mercury control, specific catalytic reduction for NO{sub x} control, and offgas retention tanks for holding the offgas until sample analysis is conducted to verify that the offgas meets emission limits. Results show that the high-performance dry-wet APCS can easily meet all expected emission limits except for possibly mercury. The capability to achieve high levels of mercury control (potentially necessary for thermally treating some DOE mixed streams) could not be validated using current performance data for mercury control technologies. The engineering approach and ASPEN PLUS modeling tool developed and used in this study identified APC equipment and system performance, size, cost, and other issues that are not yet resolved. These issues need to be addressed in feasibility studies and conceptual designs for new facilities or for determining how to modify existing facilities to meet expected emission limits. The ASPEN PLUS process simulation with current and refined input assumptions and calculations can be used to provide system performance information for decision-making, identifying best options, estimating costs, reducing the potential for emission violations, providing information needed for waste flow analysis, incorporating new APCS technologies in existing designs, or performing facility design and permitting activities.

    Systematic ethics support in community health services in Norway is in the initial phase. There are few evaluation studies about the significance of ethics reflection on care. The aim of this study was to evaluate systematic ethics reflection in groups in community health (including nursing homes and residency), - from the perspectives of employees participating in the groups, the group facilitators and the service managers. The reflection groups were implemented as part of a research and development project. A mixed-methods design with qualitative focus group interviews, observations and written reports were used to evaluate. The study was conducted at two nursing homes, two home care districts and a residence for people with learning disabilities. Participants were employees, facilitators and service managers. The study was guided by ethical standard principles and was approved by the Norwegian Social Science Data Services. We found support for ethics reflection as a valuable measure to strengthen clinical practice. New and improved solutions, more cooperation between employees, and improved collaboration with patients and their families are some of the results. No negative experiences were found. Instead, the ethics reflection based on experiences and challenges in the workplace, was described as a win-win situation. The evaluation also revealed what is needed to succeed and useful tips for further development of ethics support in community health services. Ethics reflection groups focusing on ethical challenges from the participants' daily work were found to be significant for improved practice, collegial support and cooperation, personal and professional development among staff, facilitators and managers. Resources needed to succeed were managerial support, and anchoring ethics sessions in the routine of daily work.

    Full Text Available It has been well acknowledged that Vessel Traffic Services (VTS has played a growing important role to ensure the safety of navigation in the busy ports and waterways. However, the benefits produced by VTS are usually ignored by the public and private sectors. Besides, the previous evaluations generally exist following problems: (1 It is difficult to collect the data for the parameters in the evaluation models and/or the parameters are designed illogically; (2 Those models did not take the following factors into consideration such as reducing the frequency of coastal vessel patrolling and saving human and material resources; (3 It is difficult to clearly discriminate the benefits derived from VTS and non-VTS. In this paper, a framework is presented to calculate the benefits of VTS in China. Four key indicators (safety, traffic efficiency, environmental protection and reducing supervising cost and quantitative methods have been introduced into the framework. When calculating the benefits quantitatively, the traffic condition before the construction (expansion of the VTS has acted as a benchmark. For a case study, the project of the expansion of VTS in Zhoushan Port, East China was evaluated with 10-year data. According to the results, the largest contribution is from the benefit of environmental protection. Via Cost-benefit analysis the benefit cost ratio (B/C of the VTS is up to 5.248, which shows the benefits produced by VTS are considerable. The research could provide references for VTS benefits evaluation and investment optimizing.

    Measurement of social cognition in treatment trials remains problematic due to poor and limited psychometric data for many tasks. As part of the Social Cognition Psychometric Evaluation (SCOPE) study, the psychometric properties of 8 tasks were assessed. One hundred and seventy-nine stable outpatients with schizophrenia and 104 healthy controls completed the battery at baseline and a 2-4-week retest period at 2 sites. Tasks included the Ambiguous Intentions Hostility Questionnaire (AIHQ), Bell Lysaker Emotion Recognition Task (BLERT), Penn Emotion Recognition Task (ER-40), Relationships Across Domains (RAD), Reading the Mind in the Eyes Task (Eyes), The Awareness of Social Inferences Test (TASIT), Hinting Task, and Trustworthiness Task. Tasks were evaluated on: (i) test-retest reliability, (ii) utility as a repeated measure, (iii) relationship to functional outcome, (iv) practicality and tolerability, (v) sensitivity to group differences, and (vi) internal consistency. The BLERT and Hinting task showed the strongest psychometric properties across all evaluation criteria and are recommended for use in clinical trials. The ER-40, Eyes Task, and TASIT showed somewhat weaker psychometric properties and require further study. The AIHQ, RAD, and Trustworthiness Task showed poorer psychometric properties that suggest caution for their use in clinical trials. © The Author 2015.

    The purpose of this study was to ascertain how well different wound assessment tools meet the needs of nurses in carrying out general wound assessment and whether current tools are fit for purpose. The methodology employed was evaluation research. In order to conduct the evaluation, a literature review was undertaken to identify the criteria of an optimal wound assessment tool which would meet nurses' needs. Several freely available wound assessment tools were selected based on predetermined inclusion and exclusion criteria and an audit tool was developed to evaluate the selected tools based on how well they met the criteria of the optimal wound assessment tool. The results provide a measure of how well the selected wound assessment tools meet the criteria of the optimal wound assessment tool. No tool was identified which fulfilled all the criteria, but two (the Applied Wound Management tool and the National Wound Assessment Form) met the most criteria of the optimal tool and were therefore considered to best meet nurses' needs in wound assessment. The study provides a mechanism for the appraisal of wound assessment tools using a set of optimal criteria which could aid practitioners in their search for the best wound assessment tool.

    Full Text Available The use of intellectual capital (IC is considered in developed countries as a strategic management tool for achievement of the organizations' success in innovative activities. The article is aimed at studying the foreign experience of evaluating intellectual potential of organizations and identifying directions for its advancement and use at the domestic enterprises to improve their innovative activity. An approach to capital structure has been developed, in which the following three parts are allocated: human capital, structural capital, capital of interactions. The proposed general model for research of IC in terms of firm or region allows to evaluate not only the potential, but also several important lines of communication, namely: industrial-technological, market-customer, business environment and society, commercial operations (technology, value creation and the overall development strategy. In the proposed version of studying the IC potential, analytics are combined with management of both strategy and development tactics, based on use of resources of intellectual capital. The scheme of development management through the system of the activities of influence is recommended as well. The end result of the analytical project work provides the development package, which is issued as a supporting document of development strategy. Evaluation of the development level of intellectual capital in the context of individual enterprises and of regional complex in general has been recommended to include in the Regional innovation system (RIS as one of its functional tasks

    Photocatalytic degradation of rosuvastatin, which is a drug that has been used to reduce blood cholesterol levels, was studied in this work employing ZnO as catalyst. The experiments were carried out in a temperature-controlled batch reactor that was irradiated with UV light. Preliminary the effects of the photocatalyst loading, the initial pH and the initial rosuvastatin concentration were evaluated. The experimental results showed that rosuvastatin degradation is primarily a photocatalytic process, with pseudo-first order kinetics. The byproducts that were generated during the oxidative process were identified using nano-ultra performance liquid chromatography tandem mass spectrometry (nano-UPLC–MS/MS) and acute toxicity tests using Daphnia magna were done to evaluate the toxicity of the untreated rosuvastatin solution and the reactor effluent. - Highlights: • The photocatalytic degradation of rosuvastatin was studied under UV irradiation. • Commercial catalyst ZnO was used. • Initial rosuvastatin concentration, photocatalyst loading and pH were evaluated. • The byproducts generated during the oxidative process were detected and identified. • Acute toxicity tests using Daphnia magna were carried out.

    An evaluative study aimed to capture the 'mentor voice' and provide an insight into the mentoring role from the perspective of the nurse mentor. Participants from each of the four fields of nursing practice were asked to comment on the satisfying and frustrating aspects of their mentoring role. The narrative data gleaned from the evaluation were qualitatively analysed and subsequently organised into key themes around the student-mentor relationship and the clinical environment. Given that the landscape of nurse education is set to change, in terms of new standards from the professional bodies and the political drivers, not to mention the changing profile of the student nurse, it is hoped that the findings may help to shape the relationship between the mentor, the student and the higher education institution.

    Optimal experimental design is important for the efficient use of modern highthroughput technologies such as microarrays and proteomics. Multiple factors including the reliability of measurement system, which itself must be estimated from prior experimental work, could influence design decisions. In this study, we describe how the optimal number of replicate measures (technical replicates) for each biological sample (biological replicate) can be determined. Different allocations of biological and technical replicates were evaluated by minimizing the variance of the ratio of technical variance (measurement error) to the total variance (sum of sampling error and measurement error). We demonstrate that if the number of biological replicates and the number of technical replicates per biological sample are variable, while the total number of available measures is fixed, then the optimal allocation of replicates for measurement evaluation experiments requires two technical replicates for each biological replicate. Therefore, it is recommended to use two technical replicates for each biological replicate if the goal is to evaluate the reproducibility of measurements.

    2005-10-01

    Full Text Available Star port propellant grains have been extensively studied for their operating as well as geometrical parameters. It is observed that reduced tail-off and better neutrality cannot be achieved simultaneously in a configuration. Parametric study is conducted to know the effect of various parameters of star-shaped propellant grains for ballistic evaluation motor. For reduced tail-off, higher characteristic velocity, lower outer diameter of the star, and lower value of angular fraction is preferred. Star angle, burning rate, and throat diameter have negligible effects on the tail-off factor. For better neutrality, higher value of angular  fraction, higher star outer diameter, and star angle near to neutrality, is needed. An alternate configuration is suggested using this parametric study to ascertain least tail-off and enhanced neutrality.

    Besides the original purpose of electric power generation, the Paldang dam plays such important roles as flood control and water supply in the Han river. However, significant drawdown of the downstream water level since 1973 has caused considerable differences between the real discharges and the estimated values currently in use. This study was performed to improve discharge evaluation method and to provide new discharge table appropriate for the changed condition. Through the physical model tests assisted by numerical test, the discharge equations were modified, the discharge table was revised for steady and unsteady flow conditions, but the gate operation rules proved reasonable and remained unchanged.

    2014-11-01

    This article examines the use of action learning sets in a leadership module delivered by a university in south east England. An evaluation research study was undertaking using survey method to evaluate student engagement with action learning sets, and their value, impact and sustainability. Data were collected through a questionnaire with a mix of Likert-style and open-ended questions and qualitative and quantitative data analysis was undertaken. Findings show that engagement in the action learning sets was very high. Action learning sets also had a positive impact on the development of leadership knowledge and skills and are highly valued by participants. It is likely that they would be sustainable as the majority would recommend action learning to colleagues and would consider taking another module that used action learning sets. When compared to existing literature on action learning, this study offers new insights as there is little empirical literature on student engagement with action learning sets and even less on value and sustainability.

    In this study, hazards of hydrogen and the risk due to storage of tritium are reviewed. The safety related factors are suggested in terms of classification of hydrogen hazards and problems related to the tritium storage. The major design parameters of the vessel of foreign countries for the storage and transport of tritium are reviewed. By review of major safety parameters related to the tritium storage, the results of this study can be applied and helpful to the development and design of tritium storage vessel in Korea. Also, the results can be useful at design of the tritium treatment facility. The integrity of tritium storage vessel material was evaluated with considering the embrittlement of metal material in hydrogen environment. The tritium storage is one of the most important problems for the safety of tritium removal facility. The research for tritium storage could be divided into two parts, one is for the metal getter of tritium and the other is for the integrity of tritium storage vessel. Especially, the integrity of tritium storage vessel is up to the tritium embrittlement of vessel materials, for tritium vessel is mostly made of metal material. In this work, the evaluation of the tritium embrittlement for the tritium storage vessel material is performed with the equipment that is made for high temperature and high vacuum. 33 refs., 56 figs., 23 tabs.

    Micronomicin (MCR) is a new aminoglycoside antibiotic produced by Micromonospora sagamiensis var. nonreducans which was isolated from soil collected at Sagamihara by Nara et al. The purified antibiotic showed a close similarity to gentamicin C complex in physical and chemical properties. The antibacterial activity of MCR is broad-spectrum and almost equal to that of gentamicin C complex. MCR exhibits particularly high activity against Pseudomonas, Proteus, Klebsiella pneumoniae, Serratia, etc. and high activity against some Pseudomonas aeruginosa strains resistant to gentamicin C1a. Teratogenicity studies of MCR in rats were carried out by intravenous injection for safety evaluation (Dose; 25, 50 mg/kg and 75 mg/kg). The results of studies are as follows. 1. Fetal malformation attributable to MCR was not observed at any dose. 2. Suppression of maternal weight gain was observed at the dose levels of 50 mg/kg and over. 3. There was no adverse effect on new borns at any dose.

    In Japan, expenses for landfilling yield about 400 USD per ton of ash, which gives an incentive to reduce the amount of landfilled ash. At NIES (National Institute for Environmental Studies) in Tsukuba, Japan, the AMT process (Accelerated Mineralization Technology) was developed aiming at the treatment of ashes and production of soil-like material for reuse. The objective of the project EJA was to evaluate the AMT process on the basis of available information and the possibilities the process could offer with respect to the conditions present in Sweden. With support of researchers at NIES, available literature including unpublished manuscripts on the AMT process was compiled, translated and evaluated. During treatment, the ashes are washed, aged and mixed with up to 5 % by weight of biodegradable organic matter. The material is stabilized at landfill. During up to several decades, metals are demobilized through a combination of three mechanisms, viz. carbonation, clay formation, and humification. Also persistent organic pollutants (POP) are demobilized due to humification products or they are degraded anaerobically. When the treatment is completed, the reuse of the material is envisaged. Due to the long treatment period, the AMT method might not be favored by ash producers in Sweden. In the future, landfill companies could be interested in the technology, since they are experienced to handle waste at long sight. This, however, requires that the legislation does not pose any hindrance for the implementation of the method, e.g. regarding the requirement to add organic matter to the ash. Above all, it remains several years of research on the AMT process to fully understand and evaluate the underlying biological and chemical processes as well as their interaction.

    Full Text Available Objectives: The aim of the study was to analyze discomfort glare sensation in subjects aged 50 years and more in comparison with younger subjects (i.e. younger than 35 years of age. Material and Methods: The experiments were performed on a computer workstation placed in controlled lighting environment where 2 discomfort glare conditions were modeled. Each participant performed for about 1 h specially designed visual tasks, including the tests with Landolt's rings presented on the screen by a computer program. The glare evaluation method consisted of subjective evaluation of discomfort glare on the semantic glare rating scale, tests of mesopic contrast and glare sensitivity, subjective assessment of lighting quality and asthenopic symptoms. The time needed to perform the task and the number of mistakes were also recorded. The subjective evaluation of glare was compared with the Unified Glare Rating (UGR index calculated by the DIALux simulation program. Results: A higher percentage of the younger group subjects assessed glare after the experimental session as uncomfortable and intolerable than in the 50+ group, who more often assessed glare as acceptable. The assessment of discomfort glare in the younger group corresponded to higher UGR value compared to UGR value calculated by DIALux. In the 50+ group, such correlation was found only for lower discomfort glare (UGR = 19. The results showed that younger participants more frequently suffered from visual fatigue and assessed lighting as less comfortable. However, the mesopic glare sensitivity increased significantly after the experiments only in the 50+ group under both glare conditions. Conclusions: The obtained results showed that discomfort glare sensation changes with age. The younger population seems to be more sensitive and demanding than the older one in relation to discomfort glare limiting, in spite of the lack of significant objective measures of fatigue. The exposure of the elderly to

    Introduction Psychiatric diseases like anxiety, depression, schizophrenia and bipolar disorders are increasing at an alarming rate. These diseases can affect the quantity and quality of saliva leading to multiple oral diseases. Although many researchers have evaluated xerostomia in general population, its prevalence is not been assessed in patients suffering from different psychological disorders. Aim To investigate the prevalence of xerostomia and to assess the correlation between xerostomia and dryness of lip and mucosa in different psychological disorders. Materials and Methods A cross-sectional observational study was conducted over a period of six months in Department of Psychiatry and Department of Oral Medicine. Patients with anxiety, depression, schizophrenia and bipolar disorder, as diagnosed by an experienced psychiatrist, were given a questionnaire to evaluate the xerostomia. Patients with symptoms of xerostomia were subjected to oral examination by a skilled oral diagnostician to check for dryness of lips and mucosa. One hundred patients from each group of psychiatric diseases were included in the study using a consecutive sampling technique. An equal number of healthy individuals reporting to oral medicine department for routine oral screening were included as control group after initial psychiatric evaluation. Results In this study statistically significant increase in the xerostomia in psychiatric patients was recorded when compared to the control group (p<0.01). Xerostomia was significantly higher in anxiety patients (51%) followed by depression (47%), bipolar disorder (41%), schizophrenia (39%) and control group (27%). The majority of the psychiatric patients had ‘moderate’ to ‘severe’ xerostomia whereas the control group had ‘mild’ xerostomia. Xerostomia was significantly higher in younger age group (18–49 years) than in older age group and females patients had higher xerostomia than male patients. Psychiatric patients had

    To study a vitro extraction method to determine soluble mercury and mercury species in Angong Niuhuang Wan and investigate a vitro safety evaluation method, the best extraction scheme was determined after a great deal of conditioning experiments focusing on how the solvent, purification, duration of extraction and purification etc impact on mercury extraction. Soluble mercury was determined by inductively coupled plasma mass spectrometry and mercury species were determined by high performance liquid chromatography/inductively coupled plasma mass spectrometry. Result show that the best extraction method of soluble mercury and its species was ultrasonic extraction in artificial intestinal juice at 37 °C for 2 hours, letting it stand for 20 hours and taking the supermatant. The method was reproducible, which could simulate the human body environment to maximum extent. Methyl mercury, ethyl mercury and Hg2+ were not found in the extracts of Angong Niuhuang, although the content of soluble mercury was high. It Was concluded that the method could be applied to the vitro extraction and determination of soluble mercury and mercury species in Chinese traditional medicines containing cinnabar. Methyl mercury, ethyl mercury and Hg2+ could be taken as the targets of in vitro safety evaluation of Angong Niuhuang.

    Environmental auditing is an important tool to ensure consistent and effective cleaning. Our pilot study compared an alcohol-based fluorescent marking product and an adenosine-5'-triphosphate bioluminescence product for use in an environmental auditing program to determine which product was more practical and acceptable to users. Both products were tested on 15 preselected high touch objects in randomly selected patient rooms, following regular daily cleaning. A room was considered a "pass" if ≥80% of surfaces were adequately cleaned as defined by manufacturers' guidelines. A qualitative survey assessed user preference and operational considerations. Using fluorescent marking, 9 of 37 patient rooms evaluated (24%) were considered a "pass" after daily cleaning. Using adenosine-5'-triphosphate bioluminescence, 21 of 37 patient rooms passed (57%). There was great variability in results between different high touch objects. Eighty percent of users preferred the alcohol-based fluorescent marking product because it provided an effective visual aid to coach staff on proper cleaning techniques and allowed simple and consistent application. Environmental auditing using translucent, alcohol-based fluorescent marking best met the requirements of our organization. Our results reinforce the importance of involving a multidisciplinary team in evaluating and operationalizing an environmental auditing program.

    This paper summarizes the major model evaluation studies conducted for the MATHEW/ADPIC atmospheric transport and diffusion models used by the US Department of Energy's Atmospheric Release Advisory Capability. These studies have taken place over the last 15 years and involve field tracer releases influenced by a variety of meteorological and topographical conditions. Neutrally buoyant tracers released both as surface and elevated point sources, as well as material dispersed by explosive, thermally bouyant release mechanisms have been studied. Results from these studies show that the MATHEW/ADPIC models estimate the tracer air concentrations to within a factor of two of the measured values 20% to 50% of the time, and within a factor of five of the measurements 35% to 85% of the time depending on the complexity of the meteorology and terrain, and the release height of the tracer. Comparisons of model estimates to peak downwind deposition and air concentration measurements from explosive releases are shown to be generally within a factor of two to three. 24 refs., 14 figs., 3 tabs.

    Full Text Available Translation is of an absolute necessity in today’s world. Robinson (1997 states that the study of translation is an integral part of intercultural relations and of conveying scientific and technological knowledge. He further mentions that “translators need to be able to process linguistic materials quickly and efficiently; but they also need to be able to recognize problem areas and to slow down to solve them in complex analytical ways” (p. 2. This study is an attempt to explore and evaluate an oblique translation of a text from English into Persian to find the most frequent translation strategy. To reach the goal of the study, the researchers selected one hundred and ten sentences of an original English text which had been translated freely at random and compared them with their Persian counterparts. The findings of the study indicated that Persian translator used equivalent strategy with the highest percentage (45% in the translated corpus. After that, modulation, and transposition had the highest percentages respectively.

    This paper presents the methodology used to perform an evaluation of automated CD metrology SEMs for sub-half micron process control. The paper describes the evaluation strategy, the procedure used to collect and analyze the evaluation data and concludes with recommendations on how the procedure can be improved. The evaluation process was designed to estimate metrology capability and review specific application requirements envisioned for a leading edge semiconductor development and manufacturing facility at Motorola. The evaluation process consisted of a quantitative evaluation of measurement performance specifically examining the reproducibility, linearity, automation success rate, and throughput of the instrument. In addition, capabilities such as user interface, computer integration, job transportability, and technology roadmap were assessed qualitatively. Although a particular evaluation of automated CD SEMs is considered here, the principles used to develop the evaluation procedure can be applied to metrology tools in general. A discussion of the application and desired functionality of CD metrology instrumentation including performance criteria is presented for completeness.

    Cryosphere science research and development (R&D) has been strongly committed to public service, integrating natural sciences with socioeconomic impacts. Owing to the current shift from purely natural cryosphere scientific research to linking cryosphere science with so-cioeconomic and cultural science, cross-disciplinary research in this field is emerging, which advocates future cryosphere science research in this field. Utilizing the cryosphere service function (CSF), this study establishes CSF and its value evaluation system. Cryosphere service valuation can benefit the decisionmakers' and public's awareness of environmental protection. Implementing sustainable CSF utilization strategies and macroeconomic policymaking for global environmental protection will have profound and practical significance as well as avoid environmental degradation while pursuing short-term economic profits and achieving rapid economic development.

    2013-06-01

    Full Text Available Type 1 diabetes mellitus (DM is a chronic autoimmune disease in which destruction of the beta cells in the islets of Langerhans results in insulin deficiency and hyperglycemia. We only definitely know that autoimmunity is the most important effector mechanism of type 1 DM. Type 1 DM precipitates in genetically susceptible individuals after an exposure to environmental trigger. According to current data, type 1 DM-associated genes are classified as susceptibility and protective genes. This insidious disease process evolves over a period of years. Prevention of type 1 DM requires detection of the earliest events in the process. Until now, autoantibodies are generally used as a serum biomarker, but current studies about T cell and metabolome might strengthen diagnostic view. Current preventive clinical studies usually focus on environmental factors. During the natural course of type 1 DM, many strategies have been tested at different stages in the form of primary, secondary and tertiary studies. The aim of the intervention studies for type 1 diabetes is to suppress pathogenic autoreactivity, restore/preserve beta cell mass and function to sufficient levels to provide good metabolic control, and to delay or prevent disease development. Therapeutic studies evaluate the effect of antigen specific and non-specific immune interventions, restoration of the damaged beta cells and also combination of these therapies. The results of intervention studies done till now are modulation of autoimmune process and partial prevention of loss of insulin release following the diagnosis. A single long-term effective prevention has not been identified yet. Turk Jem 2013; 17: 38-45

    The goal of Idaho Steelhead Monitoring and Evaluation Studies is to collect monitoring data to evaluate wild and natural steelhead populations in the Clearwater and Salmon river drainages. During 2007, intensive population data were collected in Fish Creek (Lochsa River tributary) and Rapid River (Little Salmon River tributary); extensive data were collected in other selected spawning tributaries. Weirs were operated in Fish Creek and Rapid River to estimate adult escapement and to collect samples for age determination and genetic analysis. Snorkel surveys were conducted in Fish Creek, Rapid River, and Boulder Creek (Little Salmon River tributary) to estimate parr density. Screw traps were operated in Fish Creek, Rapid River, Secesh River, and Big Creek to estimate juvenile emigrant abundance, to tag fish for survival estimation, and to collect samples for age determination and genetic analysis. The estimated wild adult steelhead escapement in Fish Creek was 81 fish and in Rapid River was 32 fish. We estimate that juvenile emigration was 24,127 fish from Fish Creek; 5,632 fish from Rapid River; and 43,674 fish from Big Creek. The Secesh trap was pulled for an extended period due to wildfires, so we did not estimate emigrant abundance for that location. In cooperation with Idaho Supplementation Studies, trap tenders PIT tagged 25,618 steelhead juveniles at 18 screw trap sites in the Clearwater and Salmon river drainages. To estimate age composition, 143 adult steelhead and 5,082 juvenile steelhead scale samples were collected. At the time of this report, 114 adult and 1,642 juvenile samples have been aged. Project personnel collected genetic samples from 122 adults and 839 juveniles. We sent 678 genetic samples to the IDFG Eagle Fish Genetics Laboratory for analysis. Water temperature was recorded at 37 locations in the Clearwater and Salmon river drainages.

    The association of periventricular radiolucency (PVL) in normal pressure hydrocephalus (NPH) on CT scan is a common finding. However, it is difficult to differentiate NPH from atrophy or infarctions in which shunt surgery does not reverse these conditions. To distinguish NPH from these, we examined PVL by means of dynamic CT (DCT) studies. We investigated 12 elderly patients presenting with gait disturbance, urinary incontinence and mental dysfunction who had both enlarged lateral ventricles and PVL. All patients had laboratory investigations, including radioisotope and CT cisternography and Xenon CBF studies. Nine patients were shunted because of abnormal CSF dynamics. Varying degrees of clinical improvement after surgery were observed in 6 cases. A difference of arrival time (AT) between PVL and thalamus obtained from time-density-curve was calculated in each patient. The AT difference was 6.2[+-]1.5 sec. in the shunt-effective group, and 1.4[+-]1.3 sec. in both, the shunt in effective and ineligible group, this was highly significant (p<0.01). We also measured peak time (PT) in PVL, of the thalamus and anterior cerebral artery, but no significant correlation was obtained. An AT difference between PVL and thalamus obtained from DCT studies is a clinically useful diagnostic tool for the evaluation of NPH. (author).

    Discordance between the measured levels of dengue virus neutralizing antibody and clinical outcomes in the first-ever efficacy study of a dengue tetravalent vaccine (Lancet, Nov 2012) suggests a need to re-evaluate the process of pre-screening dengue vaccine candidates to better predict clinical benefit prior to large-scale vaccine trials. In the absence of a reliable animal model and established correlates of protection for dengue, a human dengue virus challenge model may provide an approach to down-select vaccine candidates based on their ability to reduce risk of illness following dengue virus challenge. We report here the challenge of flavivirus-naïve adults with cell culture-passaged dengue viruses (DENV) in a controlled setting that resulted in uncomplicated dengue fever (DF). This sets the stage for proof-of-concept efficacy studies that allow the evaluation of dengue vaccine candidates in healthy adult volunteers using qualified DENV challenge strains well before they reach field efficacy trials involving children. Fifteen flavivirus-naïve adult volunteers received 1 of 7 DENV challenge strains (n=12) or placebo (n=3). Of the twelve volunteers who received challenge strains, five (two DENV-1 45AZ5 and three DENV-3 CH53489 cl24/28 recipients) developed DF, prospectively defined as ≥2 typical symptoms, ≥48h of sustained fever (>100.4°F) and concurrent viremia. Based on our study and historical data, we conclude that the DENV-1 and DENV-3 strains can be advanced as human challenge strains. Both of the DENV-2 strains and one DENV-4 strain failed to meet the protocol case definition of DF. The other two DENV-4 strains require additional testing as the illness approximated but did not satisfy the case definition of DF. Three volunteers exhibited effusions (1 pleural/ascites, 2 pericardial) and 1 volunteer exhibited features of dengue (rash, lymphadenopathy, neutropenia and thrombocytopenia), though in the absence of fever and symptoms.

    Factor analysis was applied to dynamic study of Tc-99m MDP for the evaluation of hip joint disorders. Fifteen patients were examined; eight were normal, six was osteoarthritis in which one accompanied synovitis was included, and one was aseptic necrosis on the head of the femur. In normals, according to the Tc-99m MDP kinetics, three factor images and time-activity curves were obtained which were named as blood vessel, soft tissue, and bone factor images and curves. In the patient with osteoarthritis, increased accumulation of the hip joint was shown in bone factor image only. But in one patient, who took osteoarthritis with synovitis, marked accumulations of the Tc-99m MDP appeared not only on the bone factor image but also on the soft tissue. Operation revealed thickening synovial tissue around the hip joint, caused by inflammatory process. In follow-up studies of the patient with aseptic necrosis on the head of the left femur, exessive accumulations, which were seemed in his left hip joint on both bone and soft tissue factor images at first, were decreased respondently to the treatment of this lesion. In conclusion, the factor analysis was useful for differential diagnosis of the hip joint disorders and observation of the clinical course of the hip joint disorders.

    Health research capacity strengthening (RCS) projects are often complex and hard to evaluate. In order to inform health RCS evaluation efforts, we aimed to describe and compare key characteristics of existing health RCS evaluation frameworks: their process of development, purpose, target users, structure, content and coverage of important evaluation issues. A secondary objective was to explore what use had been made of the ESSENCE framework, which attempts to address one such issue: harmonising the evaluation requirements of different funders. We identified and analysed health RCS evaluation frameworks published by seven funding agencies between 2004 and 2012, using a mixed methods approach involving structured qualitative analyses of documents, a stakeholder survey and consultations with key contacts in health RCS funding agencies. The frameworks were intended for use predominantly by the organisations themselves, and most were oriented primarily towards funders' internal organisational performance requirements. The frameworks made limited reference to theories that specifically concern RCS. Generic devices, such as logical frameworks, were typically used to document activities, outputs and outcomes, but with little emphasis on exploring underlying assumptions or contextual constraints. Usage of the ESSENCE framework appeared limited. We believe that there is scope for improving frameworks through the incorporation of more accessible information about how to do evaluation in practice; greater involvement of stakeholders, following evaluation capacity building principles; greater emphasis on explaining underlying rationales of frameworks; and structuring frameworks so that they separate generic and project-specific aspects of health RCS evaluation. The third and fourth of these improvements might assist harmonisation.

    Full Text Available The main aim of the study is pilot evaluation of the life skills program REBOUND in a school context focusing on substance use, risk perception, and knowledge about psychoactive substances ( n IG + CG = 723 students in five schools and 46 classes, Mage = 14.8, range 14-18 for the total sample and in the subgroups gender, age, and school type. Main goal of the study is collecting evidence for program optimization. A controlled study was carried out with repeated measurement before and after the intervention (4-6 months. Multilevel analyses, ANCOVA, and logistic regression analyses were applied to measure the effects. Overall, significantly lower incidence rates of drunkenness (odds ratio [OR] = .55; p = .033, improved knowledge about psychoactive substances (p = .006, lower personal (p = .013 and general tobacco risk perception among users (p = .002, and lower general tobacco (p = .018 and cannabis (p = .000 risk perception in non-users were found in the total intervention group. In subgroups, significantly lower rates for the incidence of drunkenness can be shown for males (p = .008 and for younger participants (p = .004. Students at academic high school (German Gymnasium showed a decrease in 30-day prevalence for alcohol (p = .017 and cannabis (p = .014, and they improved in their knowledge about psychoactive substances (p = .000. In vocational high school classes (German Realschule, there was an increase in the relative alcohol risk perception of the students (p = .019. REBOUND contributes to a controlled use of alcohol and increases knowledge about psychoactive substances. REBOUND has various effects on the examined subgroups age, gender, and school type: Males, younger students, and students in academic high school benefitted more from the course regarding consumption-related criteria. We suggest a program optimization specific to school form and age, inclusion of a tobacco intervention, and the use of more gender-segregated interventions.

    The object of this study is a improvement of a gas target and targetry for increasing the radioisotope production yields. The main results are as follows 1. Improvement of beam entrance of the gas target : In this work, deep hole grid was designed for improvement of beam entrance. Using FEM(Finite Elements Method) analysis, it was verified that this design is more effective than the old one. 2. Improvement of target gas loading and withdrawing system : For the targetry, Helium gas and vacuum lines was installed for evaluating the production yields. Using these lines, it was proved that the recovery yields was improved and the residual impurity was reduced. 3. Improvement of target cooling efficiency : In case of the cylindrical target, it is more effective to use short length of target cavity for the high production yields. For improving the cooling efficiency, cooling fin was suggested to the target design. It is more effective to put the cooling fins inside the target cavity for the suppressed target pressure and density reduction effect during the proton beam irradiation. In conclusion, the target with fins inside the target cavity was better for high current irradiation and mass RI production.

    2012-01-01

    Background Services for Rheumatoid Arthritis (RA) have evolved with the development of independently led outreach Rheumatology Practitioner (RP) clinics in Primary Care (PC). Their clinical and cost effectiveness, compared with Secondary Care (SC) services, has not been assessed. The RECIPROCATE study aims to evaluate their clinical and cost effectiveness. This part of the study aimed to explore health professionals’ opinions of rheumatology outreach service. Methods Using a qualitative design, semi-structured interviews were conducted with GPs, practice nurses, hospital doctors and RPs, from one hospital and seven PC practices in Norfolk, to elicit their opinions of the service. The interviews were analysed using thematic analysis. Results All participants agreed the service was supportive and valuable providing high quality personalised care, disease management, social, and educational support. Advantages identified included convenience, continuity of care and proximity of services to home. RPs helped bridge the communication gap between PC and SC. Some participants suggested having a doctor alongside RPs. The service was considered to be cost effective for patients but there was uncertainty about cost effectiveness for service providers. Few disadvantages were identified the most recurring being the lack of other onsite services when needed. It was noted that more services could be provided by RPs such as prescribing and joint injections as well as playing a more active role in knowledge transfer to PC. Conclusions Professionals involved in the care of RA patients recognised the valuable role of the RP outreach clinics. This service can be further developed in rheumatology and the example can be replicated for other chronic conditions. PMID:22607063

    The present study aims to establish the optimal performance parameters for the maximum exergy delivery during the collection of solar energy in a flat-plate solar air heater. The procedure to determine optimum aspect ratio (length to width ratio of the absorber plate) and optimum duct depth (the distance between the absorber and the bottom plates) for maximum exergy delivery has been developed. It is known that heat energy gain and blower work increase monotonically with mass flow rate, while the temperature of air decreases; therefore, it is desirable to incorporate the quality of heat energy collected and the blower work. First it is proved analytically that the optimum exergy output, neglecting blower work, and the corresponding mass flow rate depend on the inlet temperature of air. The energy and exergy output rates of the solar air heater were evaluated for various values of collector aspect ratio (AR) of the collector, mass flow rate per unit area of the collector plate (G) and solar air heater duct depth (H). Results have been presented to discuss the effects of G, AR and H on the energy and exergy output rates of the solar air heater. The energy output rate increases with G and AR, and decreases with H and the inlet temperature of air. The exergy-based evaluation criterion shows that performance is not a monotonically increasing function of G and AR, and a decreasing function of H and inlet temperature of air. Based on the exergy output rate, it is found that there must be an optimum inlet temperature of air and a corresponding optimum G for any value of AR and H. For values of G lesser than optimal corresponding to inlet temperature of air equals to ambient, higher exergy output rate is achieved for the low value of duct depth and high AR in the range of parameters investigated. If G is high, for an application requiring less temperature increase, then either low AR or high H would give higher exergy output rate. (author)

    Aerospace microelectronic technology has become the core competence of aerospace technology. For evaluating the aerospace microelectronic industry, it is necessary to change descriptive language of goal to quantitative index that can be measured. Knowing quantified goals or tree structure and array of general goal system, with certain algorithm and processing each corresponding list or array, we can bring out a quantified general goal value. The multi-objective (multi-attribute) evaluation method and the relevant weight sum algorithm have been adopted to quantitatively evaluate and forecast the developing state of the industry. A practical example illustrates that the applied decision technique and the algorithm are feasible and effective.

    As part of NASA's Minority University Research and Education Program (MUREP), the NASA Innovations in Climate Education (NICE) project at Langley Research Center has funded 71 climate education initiatives since 2008. The funded initiatives span across the nation and contribute to the development of a climate-literate public and the preparation of a climate-related STEM workforce through research experiences, professional development opportunities, development of data access and modeling tools, and educational opportunities in both K-12 and higher education. Each of the funded projects proposes and carries out its own evaluation plan, in collaboration with external or internal evaluation experts. Using this portfolio as an exemplar case, NICE has undertaken a systematic meta-evaluation of these plans, focused primarily on evaluation questions, approaches, and methods. This meta-evaluation study seeks to understand the range of evaluations represented in the NICE portfolio, including descriptive information (what evaluations, questions, designs, approaches, and methods are applied?) and questions of value (do these evaluations meet the needs of projects and their staff, and of NASA/NICE?). In the current climate, as federal funders of climate change and STEM education projects seek to better understand and incorporate evaluation into their decisions, evaluators and project leaders are also seeking to build robust understanding of program effectiveness. Meta-evaluations like this provide some baseline understanding of the current status quo and the kinds of evaluations carried out within such funding portfolios. These explorations are needed to understand the common ground between evaluative best practices, limited resources, and agencies' desires, capacity, and requirements. When NASA asks for evaluation of funded projects, what happens? Which questions are asked and answered, using which tools? To what extent do the evaluations meet the needs of projects and

    This cross sectional study was carried out in the Department of Radiology and Imaging, Bangabandhu Sheikh Mujib Medical University, Bangladesh in collaboration with the Department of Endocrinology and Department of Histopathology of the same hospital during the period of March 2007 to February 2008 to determine efficacy of ultrasonogram in the evaluation of thyroiditis and to compare its results with color flow Doppler study. For this purpose, a total of 50 patients having clinical suspicion of thyroiditis were enrolled in this study. Ultrasound and color Doppler were done in all these patients. Then all patients underwent for FNAC in the Histopathology department. Correlation between sonographic diagnosis and histopathological diagnosis were observed. Out of these 50 patients 10(20%) were male and 40 (80%) were female with age ranging from 12 to 50 years, highest between 21 to 30 years. The mean age of the patients was 30.42±9.57 years. On unltrasonographic findings of thyroid gland 42.0% patients had regular and 58.0% had irregular margin. Seventy percent had fibrosis, 14.0% had feature of necrosis, 48.0% had lymphadenopathy. Out of all patients 6.0% had normal echogenic feature, 16.0% had increased and 78.0% decreased echogeneic feature. Twelve percent (12.0%) patients had homogeneous and 88.0% had heterogeneous pattern of echogenecity. Thirty eight percent (38%) patients had focal nodules. Sixty percent (60.0%) patients had focal swelling and 40.0% had diffuse swelling. On color flow Doppler 28.0% had normal, 38.0% had increased and 34.0% decreased vascular flow pattern. USG reports revealed that 48.0% had thyromegaly, 36.0% had thyroid nodule, 10.0% had multinodular goiter and 6.0% had thyroid abscess.

    Full Text Available Background and Design: The definition of emergent diseases includes potentially risky diseases that need urgent medical intervention. Diagnostic and therapeutic processes are managed mostly at ourpatient setting in dermatology. Therefore, it is unclear that which diseases are real emergencies and which patients apply urgently. There are a few studies assessing this topic. Our aim was to evaluate patients referred to our clinic urgently, and to review the concept of ‘‘real dermatologic emergency’’ by comparing dermatologic emergency patients and outpatients. Material and Method: A total of 800 patients (400 urgent patients, 400 outpatients were included. Demographic features, complaints, disease duration and severity, whether the disease occurs for the first time were questionned, application time and diagnosis were recorded. The opinions of patients and physicians were inquired about why they thought that the disease was emergent. Results: Most common skin diseases were acute urticaria-angioedema, contact dermatitis, and insect bite in emergency patients; acne vulgaris, verruca and tinea pedis in outpatients. Itching was more common in emergency patients. Emergency patients' complaints were more severe than those of outpatients. Patients who experience disease first time applied to emergency service more than others. Emergency patients had a shorter disease duration than outpatients. Patients and physicians revealed different reasons and criteria about the urgency of the diseases. 93.5% of patients and 49% of physicians thought that existing disease was emergent. Conclusion: Our data reveal that the concept of dermatologic emergency is unsettled. It changes according to socio-cultural, personal features and to the present health system. Determination of the main criteria of the definition of “dermatologic urgent”, and training of dermatologists, emergency centers’physicians and also of patients in this regard seem to be a necessity

    Repeated anaerobic conditions during athletic performance may cause general and local fatigue that result in postural balance deficit. Evidence suggests that improved postural balance during athletic training may decrease the risk for fallings and traumatic injuries among athletes. Twenty athletes (12 girls, 8 boys) and 20 controls (12 girls, 8 boys) ages 10-15 years participated in the current study. All athletes were active in an 8-month physical activity program, 3 times per week for 90 min., specific to basketball, soccer, or athletic training. The control children participated in physical education at school only, with no involvement in organized extracurricular sports. All participants were evaluated for postural balance in three assessments over one year (at 4-mo intervals); the Interactive Balance System machine (Tetrax device) was used to assess balance at three test times (pre-, post-, and 10 min) after a session of a repeated sprint anaerobic test, consisting of 12 × 20 m run starting every 20 sec. The athletes had better postural balance than controls. There were different group patterns of change over the sessions; a significant interaction of session and group indicated that postural balance of the groups differed. The contribution of low sway frequencies (F1) and high sway frequencies (F6) differed between the controls and the athletes group. Results suggested that although athletes had better postural balance, improvement should be encouraged during training over the sessions and seasons, with special awareness of the balance deficit that occurs immediately after anaerobic stress and at the end of the season, to decrease the risk of injuries.

    Full text of publication follows: The construction of the 500 MWe Prototype Fast Breeder Reactor (PFBR) has commenced at IGCAR, Kalpakkam. PFBR has four intermediate Heat Exchangers (IHX) and two primary Sodium Pumps. The secondary circuits consist of two loops with each loop having one secondary pump, two intermediate heat exchangers, one surge tank and four steam generators. Primary circuit has both hot and cold sodium and is separated into hot and cold pools by Inner Vessel(IV). IHX forms the interface between the primary circuit and secondary circuit of PFBR. The IHX and pumps are supported from at the top in the roof slab and penetrate through the conical portion of inner vessel. Proper sealing arrangements are necessary to prevent leakage of hot sodium into the cold pool through the penetration. The Mechanical Seal is employed to minimize the leakage through the penetration. This seal arrangement can facilitate Differential radial and thermal expansion between IHX and IV stand pipe at the region of penetration Relative tilting between the axis of IHX and IV stand pipe Smooth installation during commissioning and easy removal during maintenance Minimizes the forces transmitted to IV The hydraulic simulation study, of the IHX - IV mechanical seal assembly was undertaken at the Fluid Control Research Institute, Palghat. The seal has two leakage paths viz. Axial and radial. The leakage depends on the contact pressure on the sealing surface and the head causing the leakage. High leakage flow may lead to damage of inner vessel and may affect the thermal efficiency of the IHX. CFD analysis of the geometry was done in detail. This was done for prototype and the model condition. The optimized design obtained using CFD was employed for experimental evaluation. In the experimental set up, the leakage characteristics was studied for varying axial and radial clearance that prevails during the various stages of operation of the seal assembly in the reactor.

    Full Text Available Education system is one of the basic systems that shape the social structure. Like all systems, the education system is made up of certain elements. Each of these elements which are attached to and complement one another just like the pieces of a jigsaw puzzle has an important function within the education system. These elements constituting the education system are purpose, content, the teaching-learning process and evaluation (Yaşar 2008, 2; Karadüz 2009, 193-194. Evaluation, one of these elements, allows determining the applications carried out in the education system; the functioning of the system; and the effectiveness of each part that constitutes the system. Johnson and Johnson (2002, 96 state that the purposes of the dimension of evaluation include determining the current knowledge and skills of students; monitoring the process executed to achieve the educational goals determined with the help of the education programs; and making a judgment regarding students’ learning. One of the evaluations made in the education process includes studies regarding the evaluation of education programs, and another one covers evaluation studies carried out in the instructional process. The evaluation applications carried out for students allow evaluating students’ learning as well as their skills, attitudes and study habits (Popham, 2008. In every phase of the education system, it is necessary to make decisions regarding both the system and its elements and those taking charge in the system and the students constituting the basis of the system as well as regarding the applications carried out, to determine the malfunctions and deficiencies and accordingly to make the necessary corrections and changes. This is only possible if the necessary decisions are made as a result of the evaluations regarding instruction, students’ achievements, students’ levels of learning and development, student selection and placement, appropriate educational guidance

    The Service Oriented Architecture (SOA) model is fast gaining dominance in how software applications are built. They allow organizations to capitalize on existing services and share data amongst distributed applications. The automatic evaluation of SOA systems poses a challenging problem due to three factors: technological complexity, organizational incompatibility, and integration into existing development pipelines. In this paper we describe our experience in developing and deploying an automated evaluation capability for the Marine Corps' Tactical Service Oriented Architecture (TSOA). We outline the technological, policy, and operational challenges we face and how we are addressing them.

    Cities′ ability reducing earthquake disasters is a complex system involving numerous factors, moreover the re-search on evaluating cities′ ability reducing earthquake disasters relates to multi-subject, such as earthquake sci-ence, social science, economical science and so on. In this paper, firstly, the conception of cities′ ability reducingearthquake disasters is presented, and the ability could be evaluated with three basic elements - the possible seis-mic casualty and economic loss during the future earthquakes that are likely to occur in the city and its surround-ings and time required for recovery after earthquake; based upon these three basic elements, a framework, whichconsists of six main components, for evaluating city′s ability reducing earthquake disasters is proposed; then thestatistical relations between the index system and the ratio of seismic casualty, the ratio of economic loss and re-covery time are gained utilizing the cities′ prediction results of earthquake disasters which were made during theninth five-year plan; at last, the method defining the comprehensive index of cities′ ability reducing earthquakedisasters is presented. Thus the relatively comprehensive theory frame is set up. The frame can evaluate cities′ability reducing earthquake disasters absolutely and quantitatively and consequently instruct the decision-makingon reducing cities′ earthquake disasters loss.

    In order to bridge the gap between preliminary screening of chemicals for potential rodent repellency and the application ofthese compounds to paper cartons, more advanced studies in the evaluation ofpromising materials have been carried out. These studies have resulted in: (1) a modification of the food acceptance technique which eliminates doubtful compounds and also provides a closer analogy to the ultimate goal, and (2) a method for rapidly testing chemicals incorporated in paper. When the results of these latter tests are expressed as a function of time, it can be shown that a distinct correlation exists between the deterrency exhibited by treated paper and the repellency of treated food.

    2015-02-01

    This paper reports a pilot study of Context Evaluation using a self-developed questionnaire distributed among engineering undergraduates at a university under study. The study aims to validate the self-developed questionnaires used in the Context evaluation, a component in the CIPP Model. The Context evaluation assesses background information for needs, assets, problems and opportunities relevant to beneficiaries of the study in a defined environment. Through the questionnaire, background information for the assessment of needs, assets and problems related to the engineering undergraduates' perceptions on the teaching and learning of technical oral presentation skills was collected and analysed. The questionnaire was developed using 5-points Likert scale to measure the constructs under study. They were distributed to 100 respondents with 79 returned. The respondents consisted of engineering undergraduates studied at various faculties at one technical university in Malaysia. The descriptive analysis of data for each item which makes up the construct for Context evaluation is found to be high. This implied that engineering undergraduates showed high interest in teaching and learning of technical oral presentation skills, thus their needs are met. Also, they agreed that assets and facilities are conducive to their learning. In conclusion, the context evaluation involving needs and assets factors are both considerably important; their needs are met and the assets and facilities do support their technical oral presentation skills learning experience.

    1992-08-01

    This paper reports that constructing an accurate Monte Carlo representation of a complex nuclear formation evaluation tool requires careful matching of computed values to the results of laboratory experiments. The availability of only finite computing resources forces restraint in the step by step addition of complexity to the model. Once confidence in the model has been established, it can be used to predict tool response to many situations not reproducible in a laboratory. High temperatures, high pressures, and pore fluids composed of liquid-gas mixtures are typical of conditions encountered in real oil wells that are difficult to reproduce in a laboratory. Tool design and the effects of design modifications can also be evaluated efficiently using the model.

    Full Text Available With the increasing of coal mining depth, the mining conditions are deteriorating, and dynamic hazard is becoming more likely to happen. This paper analyzes the relations and differences between rockburst in the coal mine and rockburst in the metal mine. It divides coal mine rockburst into two types including static loading type during roadway excavation process and dynamic loading type during mining face advancing. It proposes the correlation between the formation process of rockburst and the evolution of overlying strata spatial structure of the stope, criterion of rockburst occurrence, new classification, and predictive evaluation method for rockburst hazard that rockburst damage evaluation (RDE = released energy capacity (REC/absorbed energy capacity (AEC. Based on the relationship between RDE value and its corresponding level of rockburst hazard, the rockburst hazard can be divided into five types and evaluation index of each type can be achieved. Then the ongoing rockburst damage level can be classified in one of the five types, and the relative parameters, such as hazard extent, controlling measures also can be achieved. This new quantitative method could not only assess the impacting direction of rockburst occurrence, but also verify the effect of preventive measures for rockburst.

    2009-03-01

    Full Text Available Abstract Background The Ministry of Health and Medical Education in the Islamic Republic of Iran has undertaken a reform of its health system, in which-lower level managers are given new roles and responsibilities in a decentralized system. To support these efforts, a United Kingdom-based university was contracted by the World Health Organization to design a series of courses for health managers and trainers. This process was also intended to develop the capacity of the National Public Health Management Centre in Tabriz, Iran, to enable it to organize relevant short courses in health management on a continuing basis. A total of seven short training courses were implemented, three in the United Kingdom and four in Tabriz, with 35 participants. A detailed evaluation of the courses was undertaken to guide future development of the training programmes. Methods The Kirkpatrick framework for evaluation of training was used to measure participants' reactions, learning, application to the job, and to a lesser extent, organizational impact. Particular emphasis was put on application of learning to the participants' job. A structured questionnaire was administered to 23 participants, out of 35, between one and 13 months after they had attended the courses. Respondents, like the training course participants, were predominantly from provincial universities, with both health system and academic responsibilities. Interviews with key informants and ex-trainees provided supplemental information, especially on organizational impact. Results Participants' preferred interactive methods for learning about health planning and management. They found the course content to be relevant, but with an overemphasis on theory compared to practical, locally-specific information. In terms of application of learning to their jobs, participants found specific information and skills to be most useful, such as health systems research and group work/problem solving. The least

    Energy Technology Data Exchange (ETDEWEB)

    Olsen, Erik A.; French, Rod A.; Ritchey, Alan D.

    1995-09-01

    In 1992, the Northwest Power Planning Council approved the Hood River and Pelton ladder master plans within the framework of the Columbia River Basin Fish and Wildlife Program. The master plans define an approach for implementing a hatchery supplementation program in the Hood River subbasin. The hatchery program as defined in the master plans is called the Hood River Hatchery Production Program (HRPP). The HRPP will be phased in over several years and will be jointly implemented by the Oregon Department of Fish and Wildlife (ODFW) and the Confederated Tribes of the Warm Springs (CTWS) Reservation. In December 1991, a monitoring and evaluation program was implemented in the Hood River subbasin to collect life history and production information on stocks of anadromous salmonids returning to the Hood River subbasin. The program was implemented to provide the baseline information needed to: (1) evaluate various management options for implementing the HRPP and (2) determine any post-project impacts the HRPP has on indigenous populations of resident fish. Information collected during the 1992-94 fiscal years will also be used to prepare an environmental impact statement (EIS) evaluating the program`s impact on the human environment. To begin construction on project facilities, it was proposed that the HRPP be implemented in two phases. Phase I would include work that would fall under a {open_quotes}categorical exclusion{close_quotes} from NEPA, and Phase II would include work requiring an EIS prior to implementation. This report summarizes the life history and escapement data collected in the Hood River subbasin and the status work of implemented under Phase I of the HR Life history and escapement data will be used to: (1) test the assumptions on which harvest and escapement goals for the Hood River and Pelton ladder master plans are based and (2) develop biologically based management recommendations for implementing the HRPP.

    For the gradual maturity of Bayesian survival analysis theory, as well as the defects of the traditional methods for storage reliability evaluation, the Bayesian survival analysis method is proposed to build regression models for reliability in the random truncated test. These models can reflect the influences of different environments on the ammunition storage lifetime. As an example, the common exponential distribution is used here, and Markov chain Monte Carlo(MCMC)method based on Gibbs sampling dynamically simulates the Markov chain of the parameters' posterior distribution. Also,the parameters' Bayesian estimations are calculated in the random truncated condition. The simulation results show that the proposed method is effective and directly perceived.

    2000-07-25

    This DIE applies to the surface facilities component of the Yucca Mountain Site Characterization Project (W) ESF. The ESF complex-including surface and subsurface accommodations--encompasses an area that is approximately six miles wide and nine miles long (approximately 30,000 acres total) (United States Department of Energy [DOE] 1997, p. 9.04). It is located on federally withdrawn lands, near the southwest border of the Nevada Test Site (NTS) in southern Nevada (DOE 1997, p. 9.04). Site characterization activities are conducted within the subsurface ESF to obtain the information necessary to determine whether the Yucca Mountain Site is suitable as a geologic repository for spent nuclear fuel and high-level radioactive waste. Most ESF surface facilities are located within the Conceptual Controlled Area Boundary (CCAB) (DOE 1997, p. 9.04), with the exception of the southeastern most portions of the H-Road and the Water Supply System. Various SBT activities are also conducted throughout the Yucca Mountain region as a part of the overall site-characterization effort. In general, the DIE for SBT Activities (Civilian Radioactive Waste Management System [CRWMS] Management and Operating Contractor [M&O] 1998a) evaluates activities associated with SBT. Potential test-to-test interference and waste isolation impacts associated with SBT activities are also evaluated in CRWMS M&O (1998a).

    Full Text Available Given increasing demand for timely and accurate information to support decision making, hospitals, a particularly complex type of service organization, have increasingly resorted to a wide range of tools such as the Clinical Information Systems (CIS. However, research has shown that such systems do not always meet hospital managers’ needs, and assessment processes are necessary both before and after CIS implementation. Aiming to identify whether the CIS do meet hospital managers’ information needs and do fit in the specificities of such organizations, this paper reports on the assessment of four CIS based on the perspective of their users in four hospitals in the Metropolitan Region of Belo Horizonte, State of Minas Gerais, Brazil. The data was collected by means of semi-structured interviews and non-obtrusive observation. On the one hand, the result shows that the four organizations have difficulties in using their systems, such as accessibility problems, inadequate training and system underutilization. On the other hand, they also benefit from such systems, as they make processes faster and enable information control. One can say that the results from this research contribute to a better understanding of evaluating information systems in hospitals. Managers of such organizations can benefit from these results when seeking to evaluate and improve their information systens.

    In problem-based learning (PBL), students are actively engaged with psychological learning principles as activation of prior knowledge, elaboration and organization of knowledge. In their tutorial groups, however, students do not always apply these principles when working with a procedure like the "Seven-Jump" method. To stimulate students to use these principles more often, they were offered another format within a PBL context: PBL with study teams. During the period of self-study, students work on a regular basis in so-called study teams, small groups of 3-4 persons. In these groups they explain to each other their learning outcomes, clarify for each other their problems while studying texts and organize their knowledge to present this to the members of other study teams in their tutorial group. Previous research showed that students spent more time on self-study in a PBL with study team condition than in a traditional PBL context. In this study the achievement as well as appreciation of students participating in a PBL with study teams' environment, is compared with students working in a traditional PBL environment. To determine whether PBL with study teams differs from the traditional PBL environment in students' appreciation and study time. We conducted an experiment in two blocks over two years. Questionnaires were administered to collect data on appreciation and time for self-study. Students' appreciation of the two formats did not differ much. The large standard deviations indicate considerable differences in appreciation between individual students. Appreciation was slightly higher in the second experiment when instructions about how to collaborate were less strict. Students devoted twice as many hours studying in the study group format compared with the traditional PBL format. The students indicated that they enjoyed the format but that the increased workload disturbed their customary study rhythm. Assessment scores and tutors'impressions suggest that

    Full Text Available The first part of this investigation explored the multidimensional nature of product meaning, referring to the variety of connotations and functions a consumer associates with a particular product category. The subsequent experiment examined the moderation effects of product meaning and other attributes of the user on (a the affective evaluation of an obstructed use interaction, and (b the transfer of emotion between devices presented as being either of the same or a different brand. Although the failure experience essentially caused frustration, this reaction varied substantially among consumers depending on product meaning, age, and gender. The results also showed that the emotion dimensions of pleasure, arousal, and dominance were affected in distinct ways, and that, in addition to the consumer variables, transfer was mainly dependent on the brand relation. Nevertheless, user frustration did not cause general brand aversion, indicating that poor designs do not unconditionally threaten the customer relationship.

    2011-01-01

    A significant number of patients requiring critical care are now being managed outside of critical care facilities. There is evidence that staff looking after these patients lack the necessary knowledge and skills to care for them safely, and that effective pre-registration education can play a significant role in addressing these shortfalls in nurses' knowledge and skills. A team from Sheffield Hallam University, in collaboration with the University of Sheffield, developed a pilot one day interprofessional acute illness programme which was called SMART® (Student Management of Acute illness - Recognition and Treatment). To evaluate the pilot programme, 16 student doctors and 72 student nurses were recruited. A pre- and post-course questionnaire based on the Featherstone et al. (2005) evaluation of ALERT was used to ascertain the students' general level of knowledge of the deteriorating patient, their experiences of and confidence in caring for an acutely unwell patient, and their level of comfort with interprofessional working. The results from the pilot study indicate that the students' levels of knowledge, their levels of confidence and their comfort with interprofessional working all rose after undertaking the programme. The pilot study has a number of implications for the future teaching and learning of acute care clinical skills, within a theoretically based curriculum.

    Introduction: Endometriosis is a heterogeneous disease characterized by a range of different presentations. It is usually diagnosed when patients present with pain and/or infertility, but it has also been diagnosed in asymptomatic patients. Because of the different diagnostic approaches and diverse therapies, time to diagnosis can vary considerably and the definitive diagnosis may be delayed, with some cases not being diagnosed for several years. Endometriosis patients have many unmet needs. A systematic registration and follow-up of endometriosis patients could be useful to obtain an insight into the course of the disease. The validation of biomarkers could contribute to the development of diagnostic and predictive tests which could help select patients for surgical assessment earlier and offer better predictions about patients who might benefit from medical, surgical or other interventions. The aim is also to obtain a better understanding of the etiology, pathogenesis and progression of the disease. Material and Methods: To do this, an online multicenter documentation system was introduced to facilitate the establishment of a prospective multicenter case-control study, the IEEP (International Endometriosis Evaluation Program) study. We report here on the first 696 patients with endometriosis included in the program between June 2013 and June 2015. Results: A documentation system was created, and the structure and course of the study were mapped out with regard to data collection and the collection of biomaterials. Conclusion: The documentation system permits the history and clinical data of patients with endometriosis to be recorded. The IEEP combines this information with biomaterials and uses it for scientific studies. The recorded data can also be used to evaluate clinical quality control measures such as the certification parameters used by the EEL (European Endometriosis League) to assess certified endometriosis centers.

    During the initial Vanguard phase of the U.S. National Children's Study (NCS), about 2000 tap water, surface wipe, and air samples were collected and analyzed immediately. The shipping conditions, analysis methods, results, and laboratory performance were evaluated to determine the best approaches for use in the NCS Main Study. The main conclusions were (1) to employ established sample analysis methods, when possible, and alternate methodologies only after careful consideration with method validation studies; (2) lot control and prescreening sample collection materials are important quality assurance procedures; (3) packing samples correctly requires careful training and adjustment of shipping conditions to local conditions; (4) trip blanks and spiked samples should be considered for samplers with short expiration times and labile analytes; (5) two study-specific results reports should be required: laboratory electronic data deliverables (EDD) of sample results in a useable electronic format (CSV or SEDD XML/CSV) and a data package with sample results and supporting information in PDF format. These experiences and lessons learned can be applied to any long-term study.

    2010-05-01

    Full Text Available Angiogenesis is the growth of new blood vessels from existing ones and it is a perquisite for the growth, invasion and metastasis of solid tumors. This complex process involves multiple steps and pathways dependent on the local balance between positive and negative regulatory factors, as well as interactions among the tumor, its vasculature and the surrounding extracellular tissue matrix. Tumors lay dormant yet viable, unable to grow beyond 2-3 mm3 in size without angiogenesis."nWith the development of novel therapies for treat-ment of several diseases, directed noninvasive imaging strategies will be critical for defining the pathophysiology of angiogenesis. Imaging modalities used to detect angiogenesis include PET, SPECT, MRI, CT, US and near-infrared optical imaging. For these modalities, methods have been developed to measure blood volume, blood flow and several other semi quantitative and quantitative kinetic hemodynamic parameters such as vascular permeability. Characteristic molecular makers of angiogenesis may be visualized with the aid of molecular imaging agents such as VEGFs or the α vß3 integrin. "nMRI is a practical modality for assessing angiogenesis over time because it is already widely used clinically to assess tumor growth and for response evaluation. Anatomical information can be co registered with functional and molecular information within a single imaging method. Moreover, MRI does not involve ionizing radiation and the commonly used contrast agent has low toxicity. "nSuper paramagnetic iron oxides (SPIO are FDA-approved contrast agents for use in magnetic reson-ance (MR imaging. Most of the administered SPIO end up in the reticuloendotelial system via endocytosis and the iron core released from the SPIO is utilized in normal iron metabolism pathways. We utilize the paramagnetic characteristics of SPIO to improve the contrast of the image in MRI."nFor the first time we will introduce a method for evaluating angiogenesis

  16. Environmental education curriculum evaluation questionnaire: A reliability and validity study

    Science.gov (United States)

    Minner, Daphne Diane

    The intention of this research project was to bridge the gap between social science research and application to the environmental domain through the development of a theoretically derived instrument designed to give educators a template by which to evaluate environmental education curricula. The theoretical base for instrument development was provided by several developmental theories such as Piaget's theory of cognitive development, Developmental Systems Theory, Life-span Perspective, as well as curriculum research within the area of environmental education. This theoretical base fueled the generation of a list of components which were then translated into a questionnaire with specific questions relevant to the environmental education domain. The specific research question for this project is: Can a valid assessment instrument based largely on human development and education theory be developed that reliably discriminates high, moderate, and low quality in environmental education curricula? The types of analyses conducted to answer this question were interrater reliability (percent agreement, Cohen's Kappa coefficient, Pearson's Product-Moment correlation coefficient), test-retest reliability (percent agreement, correlation), and criterion-related validity (correlation). Face validity and content validity were also assessed through thorough reviews. Overall results indicate that 29% of the questions on the questionnaire demonstrated a high level of interrater reliability and 43% of the questions demonstrated a moderate level of interrater reliability. Seventy-one percent of the questions demonstrated a high test-retest reliability and 5% a moderate level. Fifty-five percent of the questions on the questionnaire were reliable (high or moderate) both across time and raters. Only eight questions (8%) did not show either interrater or test-retest reliability. The global overall rating of high, medium, or low quality was reliable across both coders and time, indicating

    The use of precursor ion and constant neutral loss scanning as a means of rapidly detecting drug metabolites is evaluated. Four clinically useful drugs, namely (i) cyclophosphamide, (ii) mifentidine, (iii) cimetropium bromide and (iv) haloperidol, were subjected to microsomal incubations to afford phase I metabolites. Aside from a minor clean-up procedure involving zinc sulfate precipitation of microsomal proteins and solid-phase extraction of metabolites using a Sep-pak C-18 cartridge, the mixtures were analysed directly by fast atom bombardment tandem mass spectrometry. It is demonstrated that such screening strategies are important in detecting novel metabolites. However, there are some problems associated with only using such methods, including (i) the possibility of not detecting metabolites that undergo unusual collision-induced dissociation fragmentation pathways, (ii) the non-detection of metabolites that have undergone metabolic change at unusual sites of reactivity, and (iii) production of artifacts derived from the parent drug by the primary ionization process. Examples are discussed that highlight both the strengths and weaknesses of such an approach.

    2017-02-13

    Purpose The purpose of this paper is to develop a systematic approach to predict service quality dimension's influence on service quality using a novel analysis based on data envelopment and SERVQUAL. Design/methodology/approach To assess hospital service quality in Tehran, expectation and perception of those who received the services were evaluated using SERVQUAL. The hospital service quality dimensions were found by exploratory factor analysis (EFA). To compare customer expectation and perception, perceived service quality index (PSQI) was measured using a new method based on common weights. A novel sensitivity approach was used to test the service quality factor's impact on the PSQI. Findings A new service quality dimension named "trust in services" was found using EFA, which is not an original SERVQUAL factor. The approach was applied to assess the hospital's service quality. Since the PSQI value was 0.76 it showed that improvements are needed to meet customer expectations. The results showed the factor order that affect PSQI. "Trust in services" has the strongest influence on PSQI followed by "tangibles," "assurance," "empathy," and "responsiveness," respectively. Practical implications This work gives managers insight into service quality by following a systematic method; i.e., measuring perceived service quality from the customer viewpoint and service factors' impact on customer perception. Originality/value The procedure helps managers to select the required service quality dimensions which need improvement and predict their effects on customer perception.

    This article reports on a meta-evaluation, focused on utilization, in a state in southern Brazil. This was a single case study with primary data collection using semi-structured interviews with health department administrators and staff. Content analysis used categories defined in the evaluation matrix: political and organizational context and implementation of evaluation. The political and organizational context revealed weaknesses in the items on experience, evaluation team, and time and space for reflection. Technical autonomy was verified in the State and in one municipality. In the implementation of evaluation, evaluative quality met the established criteria, but there was no prior definition of the uses and users of evaluation. One report referred to use for planning actions and political use. The study concluded that evaluation produced important information for stakeholders, with the political and organizational context as the principal limiting factor for use.

    Background and Aims Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) or biopsy is widely practiced. Optimal sonographic visualization of the needle is critical for image guided interventions. There are several commercially available needles but no bench-top testing and direct comparison of these needles to reveal their inherent echogenicity. The aims are to provide bench-top data that can be used to guide clinical applications and to promote future device research and development. Methods Descriptive bench-top testing and comparison. Bench-top testing of 8 commonly used EUS-FNA needles (all of 22 gauge in size): SonoTip Pro Control (Medi-Globe); Expect Slimline (Boston Scientific); EchoTip, EchoTip Ultra, EchoTip ProCore High Definition, (Cook Medical); ClearView (Conmed); EZ Shot2 (Olympus); BNX (Beacon Endoscopic); and 2 new prototype needles that are coated by echogenic polymers by Medi-Globe. Blinded evaluation of standardized and unedited videos by 43 EUS endoscopists and 17 radiologists specialized in gastrointestinal ultrasound examination that is unfamiliar with EUS needle devices. Results There was no significant difference in the ratings and rankings of these needles between endosonographers and radiologists. Overall, one prototype needle was rated as the best, ranking 10% to 40% higher than all other needles (pneedles, the EchoTip Ultra needle and the ClearView needle were top choices. The EZ Shot 2 needle was ranked statistically lower than other needles (30%–75% worse, pneedles have their inherent and different echogenicity, and these differences are similarly recognized by EUS endoscopists and radiologists. Needles with polymeric coating from the entire shaft to the needle tip may offer better echogenicity. PMID:26873530

    The objective of this study was to assess differences in work demands, energetic workload and workers' discomfort and physical effort in two regularly observable workdays in ironwork; one where loads up to 50kg were handled with two persons manually (T50) and one where loads up to 100kg were handled manually with four persons (T100). Differences between these typical workdays were assessed with an observational within-subject field study of 10 ironworkers. No significant differences were found for work demands, energetic workload or discomfort between T50 and T100 workdays. During team lifts, load mass exceeded 25kg per person in 57% (T50 workday) and 68% (T100 workday) of the lifts. Seven ironworkers rated team lifting with two persons as less physically demanding compared with lifting with four persons. When loads heavier than 25kg are lifted manually with a team, regulations of the maximum mass weight are frequently violated. Loads heavier than 25kg are frequently lifted during concrete reinforcement work and should be lifted by a team of persons. However, the field study showed that loads above 25kg are most of the time not lifted with the appropriate number of workers. Therefore, loads heavier than 25kg should be lifted mechanically.

    A horizontal axis micro wind turbine was tested in a low speed wind tunnel as part of a study on the icing of wind turbine blades. The turbine was monitored in order to measure the rotational speed of the rotor, axial thrust, and power output. A Kiel probe was used to measure the near wake of the turbine in relation to other wind turbines installed in a wind farm. Performance characteristics were calculated and compared with the turbine manufacturer's published data. A modified 1-D axial momentum theory was used to determine the power extracted from the wind by the rotor. Three-dimensional velocity components in the wake were measured with a hot wire anemometry technique. Results of the study were compared to actual outputs. The study showed that the model over-predicted power by 50 percent, but that the basic trend of the turbine was accurately characterized. Further studies will be conducted to determine the impact of ice growth on rotor imbalances. 27 refs., 13 figs.

    2003-04-01

    Full Text Available Previous reports in this series have indicated the growing acceptance of video-conferencing in education delivery. The current report compares a series of video-conferencing methods in an activity requiring precision of expression and communication: theatre and performance studies. The Accessing and Networking with National and International Expertise (ANNIE project is a two-year project undertaken jointly by the University of Warwick and the University of Kent at Canterbury, running from March 2001 to March 2003. The project's aim is to enhance students' learning experience in theatre studies by enabling access to research-based teaching and to workshops led by practitioners of national and international standing. Various technologies have been used, particularly ISDN video-conferencing, computer-mediated conferencing, and the Internet. This report concludes that video-conferencing methods will gain acceptance in education, as academic schools themselves are able to operate commonly available technology the assistance of specialised service units.

  3. Evaluating EML Modeling Tools for Insurance Purposes: A Case Study

    Full Text Available As with any situation that involves economical risk refineries may share their risk with insurers. The decision process generally includes modelling to determine to which extent the process area can be damaged. On the extreme end of modelling the so-called Estimated Maximum Loss (EML scenarios are found. These scenarios predict the maximum loss a particular installation can sustain. Unfortunately no standard model for this exists. Thus the insurers reach different results due to applying different models and different assumptions. Therefore, a study has been conducted on a case in a Swedish refinery where several scenarios previously had been modelled by two different insurance brokers using two different softwares, ExTool and SLAM. This study reviews the concept of EML and analyses the used models to see which parameters are most uncertain. Also a third model, EFFECTS, was employed in an attempt to reach a conclusion with higher reliability.

    This study investigated geology knowledge acquisition by Boy Scouts through use of the Boy Scout Geology Merit Handbook. In this study, boys engaged in hands-on interactive learning following the requirements set forth in the Geology Merit Badge Handbook. The purposes of this study were to determine the amount of geology content knowledge engendered in adolescent males through the use of the Geology Merit Badge Handbook published by the Boy Scouts of America; to determine if single sex, activity oriented, free-choice learning programs can be effective in promoting knowledge development in young males; and to determine if boys participating in the Scouting program believed their participation helped them succeed in school. Members of a local Boy Scout Troop between the ages of 11 and 18 were invited to participate in a Geology Merit Badge program. Boys who did not already possess the badge were allowed to self-select participation. The boys' content knowledge of geology, rocks, and minerals was pre- and post-tested. Boys were interviewed about their school and Scouting experiences; whether they believed their Scouting experiences and work in Merit Badges contributed to their success in school. Contributing educational theories included single-sex education, informal education with free-choice learning, learning styles, hands-on activities, and the social cognitive theory concept of self-efficacy. Boys who completed this study seemed to possess a greater knowledge of geology than they obtained in school. If boys who complete the Boy Scout Geology Merit Badge receive additional geological training, their field experiences and knowledge acquired through this learning experience will be beneficial, and a basis for continued scaffolding of geologic knowledge.

    Full Text Available This study was designed to assess pharmacokinetic parameters and pattern of pharmacodynamic effects (heart rate and blood pressure of 100 mg Atenolol tablets in comparison with those of 100 mg Tenormin tablets as reference. A double blind cross over study was carried out among 12 healthy male subjects. A HPLC system using RP-C18 column and fluorescence detector was used to assess atenolol in plasma. Heart rate and blood pressure were measured by the trained clinic staff. Peak levels were observed about 2.97h for Atenolol and 3.73h for Tenormin after oral dosing. Cmax values for both formulations were about 0.49 mg/ml. AUC0-24 was about 4.89 mg.h/ml for the test and 5.31 mg.h/ml for the reference group. Atenolol given orally caused a significant reduction in heart rate, systolic and diastolic blood pressure after administration of two formulations (P<0.05. It is concluded that two formulations are not significantly different in terms of pharmacodynamic and pharmacokinetic parameters which were studied.

    2009-12-01

    Full Text Available It is often difficult to provide students in introductory science courses with opportunities that mimic the investigative learning experience of doing research. This is particularly true in microbiology courses where advanced microscopy techniques are expensive and difficult to do. To that end, we developed three computer-based case studies around real-life scenarios. Our goals were to: (i improve students’ understanding of advanced microscopic techniques, (ii give students practice analyzing and interpreting data, and (iii model a scientific approach to how these techniques are applied to current issues in microbiology. Each case requires students to use references and interpret actual microscopic images, thus giving them a more realistic experience than we could previously provide. We analyzed student learning and perceptions to these case studies. After doing the case studies, students were more able to apply microscopic methods to a realistic problem, thus demonstrating an understanding of how the methods are used. Students appreciated the intellectual challenges presented by having to interpret and analyze actual microscopic images. This approach has allowed us to introduce new areas of content to our course and to stimulate critical thinking skills, a difficult task in a large introductory microbiology course.

    Green (vegetated) roofs are emerging as practical strategies to improve the environmental quality of cities. However, the impact of green roofs on the storm water quality remains a topic of concern to city planners and environmental policy makers. This study investigated whether green roofs act as a source or a sink of various metals (Na, K, Ca, Mg, Al, Fe, Cu, Cd, Pb, Zn, Mn, Cr, Ni, Li and Co), inorganic anions (NO3-, NO2-, PO4(3-), SO4(2-), Cl-, F- and Br-) and cation (NH4+). A series of green roof assemblies were constructed. Four different real rain events and several artificial rain events were considered for the study. Results showed that concentrations of most of the chemical components in runoff were highest during the beginning of rain events and subsided in the subsequent rain events. Some of the important components present in the runoff include Na, K, Ca, Mg, Li, Fe, Al, Cu, NO3-, PO4(3-) and SO4(2-). However, the concentration of these chemical components in the roof runoff strongly depends on the nature of substrates used in the green roof and the volume of rain. Based on the USEPA standards for freshwater quality, we conclude that the green roof used in this study is reasonably effective except that the runoff contains significant amounts of NO3- and PO4(3-).

    Thrombocytopenia is a common medical problem for which the main treatment is platelet transfusion. Given the increasing use of platelets and the declining donor population, identification of a safe and effective platelet growth factor could improve the management of thrombocytopenia. Thrombopoietin (TPO), the c-Mpl ligand, is the primary physiologic regulator of megakaryocyte and platelet development. Since the purification of TPO in 1994, 2 recombinant forms of the c-Mpl ligand--recombinant human thrombopoietin (rhTPO) and pegylated recombinant human megakaryocyte growth and development factor (PEG-rHuMGDF)--have undergone extensive clinical investigation. Both have been shown to be potent stimulators of megakaryocyte growth and platelet production and are biologically active in reducing the thrombocytopenia of nonmyeloablative chemotherapy. However, neither TPO has demonstrated benefit in stem cell transplantation or leukemia chemotherapy. Other clinical studies have investigated the use of TPO in treating chronic nonchemotherapy-induced thrombocytopenia associated with myelodysplastic syndromes, idiopathic thrombocytopenic purpura, thrombocytopenia due to human immunodeficiency virus, and liver disease. Based solely on animal studies, TPO may be effective in reducing surgical thrombocytopenia and bleeding, ex vivo expansion of pluripotent stem cells, and as a radioprotectant. Ongoing and future studies will help define the clinical role of recombinant TPO and TPO mimetics in the treatment of chemotherapy- and nonchemotherapy-induced thrombocytopenia.

    The rotating field collector system is an alternative concept in which all heliostats are mounted on a single large platform which rotates around a tower to track the azumuthal angle of the Sun. Each heliostat is mounted to the platform with appropriate pivots, linkage, and controls to provide the additional positioning required to properly direct the solar radiation onto the receiver. The results are presented of the first phase of a study to investigate the technical and economic merits of a particular type of rotating field collector subsystem. The large pie-shaped platform would revolve over an array of support pedestals by means of a roller at the top of each pedestal. Several heliostats were built to demonstrate their construction features, and the operation of both flat and amphitheater rotating fields was studied. Work included an analysis of the concepts, development of modifications and additions to make the system comply with design criteria, and cost estimates to be used for comparison with other heliostat subsystems. Because of considerably high cost estimates, the focus of a large part of the study was directed toward developing lower cost designs of major components.

    Full Text Available CONTEXT Upper gastrointestinal bleeding (UGIB is one of the commonest gastrointestinal emergencies encountered by clinicians. Peptic ulcers are the most common cause of UGIB. Endoscopy has become the preferred method for diagnosis in patients with acute UGIB. This study is done in a diagnostic upper gastrointestinal endoscopy (UGIE setup of a tertiary care hospital to ascertain the causes of UGIB prevalent in this part of our country which might differ from other studies. AIM To ascertain prevalent causes of UGIB in patients of this part of India admitted to a Govt. Tertiary Hospital with a provisional diagnosis of UGIB. METHOD One hundred consecutive patients with UGIB were subjected to UGIE to find out the aetiology. The clinical profile and endoscopic findings were analysed and compared with the data on UGIB from other studies. RESULTS The mean age of patients was 47.03 years with male: female ratio of 2.33:1. 58% of patients were first time bleeders. Majority of patients presented with melaena. Visualisation of active bleeding achieved to 85.7% when endoscopy was done within first 24 hrs. The commonest cause of UGIB was duodenal ulcer (DU which accounted for 41% cases. Gastric ulcer was responsible in 13% of cases. Portal hypertension was responsible for bleed in only 13%. Neoplasms accounted for 25% of cases. Other less common causes were erosive gastritis (3%, gastric polyp (3%, Mallory-Weiss tear (1%, and Dieulafoy’s lesion (1%. Among bleeding peptic ulcers, 27.8% of cases were classified as Forrest IIa and 20.4% in Forrest IIb & IIc each. Acid peptic disease was past history elicited in majority (33% followed by NSAID (26% and alcohol (26%. CONCLUSION The present study has diagnosed various causes of upper gastrointestinal bleeding in this part of country. The incidence of gastric carcinoma as a cause of upper gastrointestinal bleeding is significantly high compared to those in other studies. UGI endoscopy should be done in every case

    The joint commission recognizes effective communication among caregivers as an important factor for ensuring patient safety, especially at times when the patient's care is handed off from one caregiver or service to another. This case study reviews the course of treatment for one patient throughout the perioperative continuum, including the postoperative unit where a pre-arrest situation developed. A workshop using Bloom's Taxonomy of Educational Objectives enabled staff members to more clearly understand the patient's situation. It also allowed the participants to gain an increased understanding of significant data and has been strategic in preventing patient complications.

    2015-03-25

    The LHCb detector at CERN is scheduled to undergo an upgrade during the second long shutdown of the LHC. As part of this upgrade, the vertex detector (VELO) will be replaced with a new hybrid pixel detector, based on an evolution of the Timepix ASIC. The performance of this detector should improve upon that achieved by the current VELO, in addition to facilitating the complete detector readout at 40 MHz. As part of the preparation for this upgrade, this thesis presents the results of studies carried out on the single hit resolution of silicon hybrid pixel detectors. The development of a particle beam telescope has been carried out to allow these studies, shown to operate with track rates in excess of 45 kHz and with a pointing resolution at the device under test of less than 2 μm. A wide range of sensor types, thicknesses and resistivities have then been tested under different operating conditions and the results presented, with single hit resolutions varying between 4 μm and 12 μm depending on the conditi...

    Numerous breast phantoms have been developed to be as realistic as possible to ensure the accuracy of image quality analysis, covering a greater range of applications. In this study, we simulated three different densities of the breast parenchyma using paraffin gel, acrylic plates and PVC films. Hydroxyapatite was used to simulate calcification clusters. From the images acquired with a GE Senographe DR 2000D mammography system, we selected 68 regions of interest (ROIs) with and 68 without a simulated calcification cluster. To validate the phantom simulation, we selected 136 ROIs from the University of South Florida's Digital Database for Screening Mammography (DDSM). Seven trained observers performed two observer experiments by using a high-resolution monitor Barco mod. E-3620. In the first experiment, the observers had to distinguish between real or phantom ROIs (with and without calcification). In the second one, the observers had to indicate the ROI with calcifications between a pair of ROIs. Results from our study show that the hydroxyapatite calcifications had poor contrast in the simulated breast parenchyma, thus observers had more difficulty in identifying the presence of calcification clusters in phantom images. Preliminary analysis of the power spectrum was conducted to investigate the radiographic density and the contrast thresholds for calcification detection. The values obtained for the power spectrum exponent (β) were comparable with those found in the literature.

    Full Text Available Metallised gel propellants offer higher specific impulse and volumetric loading, reduced vaporisation loss, spillage and slosh problems and easy storage in comparison to the conventional liquid propellants. Theoretical performance analysis of gel propellant containing Al in unsymmetrical dimethyl hydrazine-dinitrogen tetroxide (UDMH-N/sub 2/O/sub 4} system shows peak Isp (vacuum condition of 316.7 s and 318.3 s at oxidiser/fuel (O/f ratios of 1.5 and 1.0, respectively for 30 per cent and 40 per cent UDMH-Al gel propellants, under standard conditions. The effect of other parameters like area ratio and chamber pressure on performance has been brought out in view of mission oriented applications. Aluminium has been found to be a better choice over magnesium in metallised gel propellants. Experimental studies on UDMH gellation using propellant grade (15 micrometerand pyrotechnic grade (1.5 micrometerAl in 500g batch level show that gellant(methyl cellulose concentration could be reduced by 50 percent using pyrotechnic grade Al. The pseudoplastic-thixotropic behaviour, flow rate through die holes, burst pressure tests and bulk density are studied. UDMH -25 to 30 per cent Al gels with both grades of Al are found to be stable, pseudoplastic (shear thinning and thixotropic (time-dependent shear thinning, but their flow pattern through die holes differ in nature.

    2013-11-01

    Coconut skim milk and insoluble protein are 2 major byproducts in the production of virgin coconut oil. Coconut skim milk was homogenized along with insoluble protein and spray dried to obtain a value-added product, namely, coconut protein powder (CPP). This study deals with the storage study of CPP under different conditions (refrigerated [control], ambient and accelerated). CPP samples were withdrawn periodically at designated intervals of 15 d for accelerated and control, and 30 d for ambient condition. CPP stored at different conditions exhibited marginal moisture uptake (by 0.74 % w/w for control, 0.76 % w/w for ambient, and 1.26 % w/w for accelerated condition) and as a result, had very little effect on the functional properties of the powder. Withdrawn CPP was tested for sensory quality aspects and subjected to instrumental analysis as well. Withdrawn CPP was incorporated as a milk substitute in dessert (Kheer). Quantitative descriptive analysis of the powder and product (Kheer) showed no significant difference in attributes of CPP during the storage period of 2 mo. Electronic nose analysis revealed that CPP samples were not much different with respect to aroma pattern matching, respectively.

    2016-10-01

    Objective. While motor-imagery based brain-computer interfaces (BCIs) have been studied over many years by now, most of these studies have taken place in controlled lab settings. Bringing BCI technology into everyday life is still one of the main challenges in this field of research. Approach. This paper systematically investigates BCI performance under 6 types of distractions that mimic out-of-lab environments. Main results. We report results of 16 participants and show that the performance of the standard common spatial patterns (CSP) + regularized linear discriminant analysis classification pipeline drops significantly in this ‘simulated’ out-of-lab setting. We then investigate three methods for improving the performance: (1) artifact removal, (2) ensemble classification, and (3) a 2-step classification approach. While artifact removal does not enhance the BCI performance significantly, both ensemble classification and the 2-step classification combined with CSP significantly improve the performance compared to the standard procedure. Significance. Systematically analyzing out-of-lab scenarios is crucial when bringing BCI into everyday life. Algorithms must be adapted to overcome nonstationary environments in order to tackle real-world challenges.

  20. Abrasive blasting agents: designing studies to evaluate relative risk.

    Science.gov (United States)

    Hubbs, Ann; Greskevitch, Mark; Kuempel, Eileen; Suarez, Fernando; Toraason, Mark

    Workers exposed to respirable crystalline silica used in abrasive blasting are at increased risk of developing a debilitating and often fatal fibrotic lung disease called silicosis. The National Institute for Occupational Safety and Health (NIOSH) recommends that silica sand be prohibited as abrasive blasting material and that less hazardous materials be used in blasting operations. However, data are needed on the relative risks associated with exposure to abrasive blasting materials other than silica. NIOSH has completed acute studies in rats (Hubbs et al., 2001; Porter et al., 2002). To provide dose-response data applicable to making recommendation for occupational exposure limits, NIOSH has collaborated with the National Toxicology Program (NTP) to design longer term studies with silica substitutes. For risk assessment purposes, selected doses will include concentrations that are relevant to human exposures. Rat lung burdens achieved should be comparable to those estimated in humans with working lifetime exposures, even if this results in "overloading" doses in rats. To quantify both dose and response, retained particle burdens in the lungs and lung-associated lymph nodes will be measured, as well as biochemical and pathological indices of pulmonary response. This design will facilitate assessment of the pulmonary fibrogenic potential of inhaled abrasive blasting agents at occupationally relevant concentrations.

  1. Student perceptions of evaluation in undergraduate medical education: A qualitative study from one medical school

    2012-06-01

    Full Text Available Abstract Background Evaluation is an integral part of medical education. Despite a wide use of various evaluation tools, little is known about student perceptions regarding the purpose and desired consequences of evaluation. Such knowledge is important to facilitate interpretation of evaluation results. The aims of this study were to elicit student views on the purpose of evaluation, indicators of teaching quality, evaluation tools and possible consequences drawn from evaluation data. Methods This qualitative study involved 17 undergraduate medical students in Years 3 and 4 participating in 3 focus group interviews. Content analysis was conducted by two different researchers. Results Evaluation was viewed as a means to facilitate improvements within medical education. Teaching quality was believed to be dependent on content, process, teacher and student characteristics as well as learning outcome, with an emphasis on the latter. Students preferred online evaluations over paper-and-pencil forms and suggested circulating results among all faculty and students. Students strongly favoured the allocation of rewards and incentives for good teaching to individual teachers. Conclusions In addition to assessing structural aspects of teaching, evaluation tools need to adequately address learning outcome. The use of reliable and valid evaluation methods is a prerequisite for resource allocation to individual teachers based on evaluation results.

    This paper describes a study of the variability of measured composition for a single bulk sugarcane bagasse conducted across eight laboratories using similar analytical methods, with the purpose of determining the expected variation for compositional analysis performed by different laboratories. The results show good agreement of measured composition within a single laboratory, but greater variability when results are compared among laboratories. These interlaboratory variabilities do not seem to be associated with a specific method or technique or any single piece of instrumentation.

    Full Text Available BACKGROUND TO THE DEBATE: The UK Medical Research Council defines complex interventions as those comprising "a number of separate elements which seem essential to the proper functioning of the interventions although the 'active ingredient' of the intervention that is effective is difficult to specify." A typical example is specialist care on a stroke unit, which involves a wide range of health professionals delivering a variety of treatments. Michelle Campbell and colleagues have argued that there are "specific difficulties in defining, developing, documenting, and reproducing complex interventions that are subject to more variation than a drug". These difficulties are one of the reasons why it is challenging for researchers to systematically review complex interventions and synthesize data from separate studies. This PLoS Medicine Debate considers the challenges facing systematic reviewers and suggests several ways of addressing them.

    Full Text Available Background: Hysteroscopy is the gold standard procedure for uterine cavity exploration. However, hysteroscopy is only recommended by the WHO when clinical or complementary exams (ultrasound, HSG suggest intrauterine abnormality or after in vitro fertilization failure. Nevertheless, many specialists feel that hysteroscopy is a more accurate tool. The aim of this prospective study is to assess the value of diagnostic hysteroscopy in a primary workup of infertility by describing hysteroscopy findings in a population of 324 infertile patients during 18 months (December 2010 - May 2012. Methods: We analysed prospectively 324 infertile patients in gynaecology OT setting. Diagnostic video-assisted hysteroscopy was performed using a flexible hysteroscope. Hysteroscopy was performed with a standard sequence, inspecting the endocervical canal, uterine cavity, endometrium, and tubal ostia and findings recorded. Results: Hysteroscopy was normal in 65.12% of patients. Cervico-isthmic abnormalities were present in 6.48% of patients with cervical stenosis being the major abnormality. Uterine cavity was normal in 86% of patients. Observed abnormalities were septate uterus in 10 cases, intrauterine synechiae in 16 cases, sub mucus myoma in 2 cases, deformed cavity in 10 cases and endometrial polyp in 2 cases. Ostial fibrosis was observed in 29 patients. Endometrial abnormalities (fibrosis, inflammation were observed in 30 patients. Seven patients turned out to be of genital tuberculosis with endometrial biopsy. No significance was found regarding the total number of intrauterine pathologies when comparing the groups of primary versus secondary infertility. Conclusions: Rates of abnormal findings in infertile patient who underwent diagnostic hysteroscopy was 34.88% in our study. Our data are an additional argument to suggest hysteroscopy as part of investigation in infertile woman. Routine diagnostic hysteroscopy should be part of an infertility workup in primary

  7. Marine zooplankton studies in Brazil: a brief evaluation and perspectives

    Directory of Open Access Journals (Sweden)

    Rubens M. Lopes

    2007-09-01

    Full Text Available Marine zooplankton research in Brazil has been primarily descriptive, with most studies focusing on community structure analysis and related issues. The composition and spatial distribution of several taxonomic groups are currently well known, although less-abundant and small-sized taxa as well as initial stages of almost all species have received little attention. Some numerically important taxa such as heterotrophic protists, ctenophores, acoel turbellarians and ostracods remain virtually unstudied. Large sectors of the continental shelf have not been sampled in detail, particularly those areas influenced by the North Brazil Current (5ºN-15ºS. Zooplankton abundance and biomass in offshore waters have seldom been quantified, and information on the distribution and vertical migration of meso- and bathypelagic species are lacking. Additional faunistic assessments must target those less-studied taxa and geographical locations. However, priority in ecological studies should be given to process-oriented investigations aimed at understanding the mechanisms controlling zooplankton distribution, trophic interactions within pelagic food webs and production cycles in relation to the physical environment. An effort should be made to incorporate state-of-the-art sampling technology and analytical methods into future research projects.As pesquisas sobre o zooplâncton marinho no Brasil têm sido primariamente descritivas, com a maioria dos estudos enfocando a análise da estrutura da comunidade e assuntos relacionados. A composição e a distribuição espacial de muitos grupos taxonômicos encontram-se bem estudadas, embora os táxons menos abundantes e de menores dimensões, assimcomo os estágios iniciais do ciclo de vida da maioria das espécies, tenham recebido pouca atenção.

    Anthroposophic medicine is a physician-provided complementary therapy system that was founded by Rudolf Steiner and Ita Wegman. Anthroposophic therapy includes special medicinal products, artistic therapies, eurythmy movement exercises, and special physical therapies. The Anthroposophic Medicine Outcomes Study (AMOS) was a prospective observational multicenter study of 1631 outpatients starting anthroposophic therapy for anxiety disorders, asthma, attention deficit hyperactivity disorder, depression, low back pain, migraine, and other chronic indications under routine conditions in Germany. AMOS INCORPORATED TWO FEATURES PROPOSED FOR THE EVALUATION OF INTEGRATIVE THERAPY SYSTEMS: (1) a sequential approach, starting with the whole therapy system (use, safety, outcomes, perceived benefit), addressing comparative effectiveness and proceeding to the major system components (physician counseling, anthroposophic medicinal products, art therapy, eurythmy therapy, rhythmical massage therapy) and (2) a mix of different research methods to build an information synthesis, including pre-post analyses, prospective comparative analyses, economic analyses, and safety analyses of individual patient data. AMOS fostered two methodological innovations for the analysis of single-arm therapy studies (combined bias suppression, systematic outcome comparison with corresponding cohorts in other studies) and the first depression cost analysis worldwide comparing primary care patients treated for depression vs depressed patients treated for another disorder vs nondepressed patients. A total of 21 peer-reviewed publications from AMOS have resulted. This article provides an overview of the main research questions, methods, and findings from these publications: anthroposophic treatment was safe and was associated with clinically relevant improvements in symptoms and quality of life without cost increase; improvements were found in all age, diagnosis, and therapy modality groups and were

    Rivers are one of the most environmentally vulnerable sources for contamination. Since the rivers pass through the cities, industrial and agricultural centers, these have been considered as place to dispose the sewages. This issue is more important when the river is one of the main sources of water supplying for drinking, agricultural and industrial utilizations. The goal of the present study was assessing the physicochemical characteristics of the Tireh River water. The Tireh River is the main river in the Karkheh catchment in the Iran. To this end, 14 sampling stations for measuring the physicochemical properties of Tireh River along the two main cities (Borujerd and Dorud) were measured. The results showed that (except SO4) Mg, Ca and other anions and cations have concentrations under WHO standard limitation. Almost all samples have suitable conditions for drinking with regard to the WHO standard and in comparison with agricultural standard (FAO Standard), and the potential of water is suitable for irrigation purposes. According to Wilcox diagram, 78 % of samples were at the C3-S1 and 21.5 % were at C2-S1 classes. The piper diagram shows that most of samples are bicarbonate and calcic facies.

  3. Doctors on Values and Advocacy: A Qualitative and Evaluative Study.

    2016-05-11

    Doctors are increasingly enjoined by their professional organisations to involve themselves in supraclinical advocacy, which embraces activities focused on changing practice and the system in order to address the social determinants of health. The moral basis for doctors' decisions on whether or not to do so has been the subject of little empirical research. This opportunistic qualitative study of the values of medical graduates associated with the Sydney Medical School explores the processes that contribute to doctors' decisions about taking up the advocate role. Our findings show that personal ideals were more important than professional commitments in shaping doctors' decisions on engagement in advocacy. Experiences in early life and during training, including exposure to power and powerlessness, significantly influenced their role choices. Doctors included supraclinical advocacy in their mature practices if it satisfied their desire to achieve excellence. These findings suggest that common approaches to promoting and facilitating advocacy as an individual professional obligation are not fully congruent with the experiences and values of doctors that are significant in creating the advocate. It would seem important to understand better the moral commitments inherent in advocacy to inform future developments in codes of medical ethics and medical education programs.

  4. IMPACT OF CONFLICT MANAGEMENT ON CORPORATE PRODUCTIVITY: AN EVALUATIVE STUDY

    Full Text Available A wide divergence of opinion exists on the source and effect of conflicts on corporate productivity and the effectiveness of the various strategies available for managing them. It has been argued by some that conflicts are signs of a vibrant organization while others contend it is destructive and capable of retarding stability and profitability of organizations. Using a student t distribution to test the significance of response and purposive sampling technique to administer a self-design questionnaires to 50 respondents cutting across all cadres of staff of First Bank of Nigeria Plc.,(Lagos Branch, revealed that the main sources of conflict in the organization relate to perception and value problems. The specific issues bother on employee compensation and welfare while managers prefer the compromise, problem solving and dominating strategies to minimizing the incidence of organisational conflicts. Based on the findings of the study, it was recommended that strategies which promote industrial democracy should be chosen by management as the preferred option in dispute resolution. In addition, the ideal level of conflict resolution required to attain optimum performance for every organisation is unique and situational hence managers are duty bound to establish the best maintainable by the organisation.

    Climate change is at the top of the present and future problems facing humanity. Climate change is now largely attributed to human activities and economic activities are the source of human activities that cause climate change by creating pressure on the environment. Providing the sustainability of resources for the future seems possible by reducing the pressure of these economic activities on the environment. Given the increasing population pressure and growth-focused economies, it is possible to say that achieving decoupling is not so easy on a global basis. It is known that there are some problems in developing countries especially in terms of accessing reliable data in transition and implementation process of decoupling. Developed countries' decoupling practices and proper calculation methods can also be a guide for developing countries. In this study, we tried to calculate the comparative decoupling index for OECD countries and Turkey in terms of data suitability, and we showed the differences between them. We tried to indicate the level of decoupling (weak, stable, strong) for each country. We think that the comparison of Turkey can be an example in terms of developing countries.

    Post-marketing-surveillance studies with herbal drugs usually are prospective prescription-epidemiological studies, which should allow statements on quality, efficacy and safety. Until now neither laws nor concrete normative guidelines for the methodology and the evaluation of post-marketing-surveillance studies are existing which could be used for pharmacovigilance. In the present paper guidelines for planning, realisation and evaluation are presented which should allow studies of high quality. The essential components required for the investigational plan are focussed. Also recommendations on the obligatory, optional and special components of the study protocols are made. Additionally statistical methods which allow the evaluation of the therapeutic efficacy are presented.

    The purpose of this study was to perform a retrieval analysis of temporomandibular joint (TMJ) alloplastic interpositional implants and test possible correlation between implant failure features and patient clinical outcomes. In addition, we investigated the implants' surface and examined the foreign body reaction associated with different types of alloplastic materials. Twelve implants (Proplast/Teflon [Vitek, Houston, TX] and Silastic [Dow Corning, Midland, MI]) were surgically removed from the patients' TMJs. Implant surface failure features (fracture length, perforation of the implants) were observed using stereomicroscopy and recorded for description of the failure mechanisms and to statistically compare with clinical outcomes. Patients' clinical data (pain symptoms and mandibular function) were collected and examined. Clinical outcomes were obtained relative to symptom severity (Symptom Severity Index [SSI]) and jaw function (modified Mandibular Function Impairment Questionnaire [mMFIQ]). Peri-implant soft tissues and implants were analyzed with light microscopy and stereo zoom microscopy. Electron microprobe analysis of implant fragments and peri-implant tissues was performed. The statistical results showed that only the presence of implant perforation was statistically associated with the SSI, specifically with the pain tolerability dimension. No statistical association was seen between any of the other implant failure predictors and the SSI and between the predictors and the mMFIQ. Stereo zoom microscopy suggested that Proplast/Teflon implants (n = 7) were susceptible to perforation, layer tearing, fracture and fiber extrusion. The Silastic implants (n = 3) revealed a possible center perforation with fracture lines towards the periphery and fiber extrusion. Teflon implant wear debris particles appear to trigger a multinucleated giant cell foreign body reaction. Facial pain was a significant correlate to perforation and breakdown of the alloplastic TMJ

    Full Text Available Background: More than 80% of patients with hematologic malignancies will develop fever during more than one chemotherapy cycle combined with neutropenia. We aim to evaluate empiric antibiotic strategies in Febrile Neutropenic (FN cancer patients.Methods: This is a concurrent study performed in the “Shahid Ghazi” teaching hospital, hematology-oncology center of Tabriz, Iran during the period of December 2011 to September2012. During this period, patients with FN were evaluated in view of antibiotics utilization based on Infectious Disease Society of America (IDSA and National Comprehensive Cancer Network (NCCN instructions.Results: Seventy patients had a total of 91 episodes of FN in the duration of this study. Among them 63 (90% patients were the cases of acute leukemia. For 88 (96.7 % patients, imipenem was used as the initial empirical antibiotic regimen. It was changed to piperacillin/tazobactam in 8 (8.8% of them without indication. Cultures didn’t obtain before the initiation of empirical therapy in 19 (20.9% episodes. Empiric vancomycin didn’t discontinue after 3 days even if it was not warranted in 23 episodes. In 16 cases vancomycin was switched to teicoplanin. The fluconazole dosages generally given to patients were all suboptimal. Adjusting the dosages of vancomycin or imipenem was not done correctly in 13 (14.29% episodes.Conclusion: The results of this study showed that choosing antimicrobial agents and their dosing for prophylaxis and treatment of FN patients and discharge antimicrobial planning of FN patients do not follow the evaluated guidelines. Drug Usage Evaluation studies need to be done regularly in such a center.

  10. Methodological study of computed tomographic evaluation of intrasellar lesions

    CT examination of sellar lesions was studied from the methodological aspect in 141 CT scans performed in 59 patients with suspected pituitary lesions. The basic scanning line was determined in parallel to the line from the tuberculum to the dorsum sella using a ''scout view'' device. The angles formed by the orbito-meatal line and the tuberculumdorsum sella line as measured in 50 adults were 1.8 +- 6.4/sup 0/ in males and -6.4 +- 4.8/sup 0/ in females. Therefore, if the CT scanner is not equipped with a scout view, these mean angles may be used as the basic scanning line. Contiguous sections were obtained with a CT/T 8800 scanner at 1.5 mm intervals through the sella, under the radiographic condition of 120 kV, 500 mA and 2 pulses, which proved suitable for the detection of minor lesions below 10 mm in size and for examination of the pituitary stalk. Window width of 250 or 300 Hounsfield units and window levels ranging from 50 to 60 were well suited to the detection of small lesions. Twenty-eight cases of pituitary adenoma, 3 of empty sella alone, and 1 of sphenoidal mucocele were confirmed by CT scan. The pituitary adenomas consisted of 8 Type I, 13 Type II, 2 Type III, and 5 Type IV after the classification of Hardy. By enhancement with a contrast medium, the normal pituitary appeared higher in density than the brain, and the intrapituitary small tumor appeared slightly lower in density than the normal pituitary. CT scanning under the above-mentioned display condition could discriminate the tumor from the normal pituitary in at least 24 cases which were surgically confirmed. Shifting or bending of the pituitary stalk found in the reconstructed coronal or sagittal sections were useful for the diagnosis of intrasellar pituitary tumors. The empty sella was effectively diagnosed by CT cisternography using metrizamide as a contrast medium.

  11. Reanalysis Data Evaluation to Study Temperature Extremes in Siberia

    Ongoing global climate changes are strongly pronounced in Siberia by significant warming in the 2nd half of 20th century and recent extreme events such as 2010 heat wave and 2013 flood in Russia's Far East. To improve our understanding of observed climate extremes and to provide to regional decision makers the reliable scientifically based information with high special and temporal resolution on climate state, we need to operate with accurate meteorological data in our study. However, from available 231 stations across Siberia only 130 of them present the homogeneous daily temperature time series. Sparse, station network, especially in high latitudes, force us to use simulated reanalysis data. However those might differ from observations. To obtain reliable information on temperature extreme "hot spots" in Siberia we have compared daily temperatures form ERA-40, ERA Interim, JRA-25, JRA-55, NCEP/DOE, MERRA Reanalysis, HadEX2 and GHCNDEX gridded datasets with observations from RIHMI-WDC/CDIAC dataset for overlap period 1981-2000. Data agreement was estimated at station coordinates to which reanalysis data were interpolated using modified Shepard method. Comparison of averaged over 20 year annual mean temperatures shows general agreement for Siberia excepting Baikal region, where reanalyses significantly underestimate observed temperature behavior. The annual temperatures closest to observed one were obtained from ERA-40 and ERA Interim. Furthermore, t-test results show homogeneity of these datasets, which allows one to combine them for long term time series analysis. In particular, we compared the combined data with observations for percentile-based extreme indices. In Western Siberia reanalysis and gridded data accurately reproduce observed daily max/min temperatures. For East Siberia, Lake Baikal area, ERA Interim data slightly underestimates TN90p and TX90p values. Results obtained allows regional decision-makers to get required high spatial resolution (0,25°×0

    2014-01-01

    An inter-laboratory evaluation study was conducted in order to evaluate the antioxidant capacity of food additives by using a 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay. Four antioxidants used as existing food additives (i.e., tea extract, grape seed extract, enju extract, and d-α-tocopherol) and 6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid (Trolox) were used as analytical samples, and 14 laboratories participated in this study. The repeatability relative standard deviation (RSD(r)) of the IC50 of Trolox, four antioxidants, and the Trolox equivalent antioxidant capacity (TEAC) were 1.8-2.2%, 2.2-2.9%, and 2.1-2.5%, respectively. Thus, the proposed DPPH assay showed good performance within the same laboratory. The reproducibility relative standard deviation (RSD(R)) of IC50 of Trolox, four antioxidants, and TEAC were 4.0-7.9%, 6.0-11%, and 3.7-9.3%, respectively. The RSD(R)/RSD(r) values of TEAC were lower than, or nearly equal to, those of IC50 of the four antioxidants, suggesting that the use of TEAC was effective for reducing the variance among the laboratories. These results showed that the proposed DPPH assay could be used as a standard method to evaluate the antioxidant capacity of food additives.

    2017-06-01

    This practice based explorative study aims to provide insight into the ways in which case managers shape and fill up the evaluation phase of their support of the informal care network of persons with dementia. A combination of quantitative and qualitative research methods were used. A group of 57 case managers of persons with dementia in three different organisational networks took part in this study. Results from the quantitative and qualitative data are organized into four themes: (1) attitude towards evaluation, (2) forms of evaluation, (3) implementation of evaluation and (4) content of evaluation. There are different ways in shaping evaluation and the content of it. The importance of interim and final evaluation is recognized, but is difficult to realize in a methodical way. Barriers experienced by the case managers include various factors associated both with clients as professionals. Case managers evaluate continuously and in an informal way to assess whether the extent of their assistance is meeting the needs of the client and informal network. Case managers do not use systematic evaluation to measure the quality of care they offer to persons with dementia and their caregivers. The findings demand a discussion on the level of clients, as well as on the professional and societal level about the way case managers should evaluate their support.

    Science.gov (United States)

    Miller, Robin Lin

    2013-06-01

    This paper comments on the papers in the special volume on logic modeling and evaluation theory. Logic modeling offers a potentially useful approach to learning about the assumptions, activities, and consequences described in an evaluation theory and may facilitate comparative analysis of evaluation theories. However, logic models are imperfect vehicles for depicting the contingent and dynamic nature of evaluation theories. Alternative approaches to studying theories are necessary to capture the essence of theories as they may work in actual practice. Copyright © 2012 Elsevier Ltd. All rights reserved.

  19. Evaluation Studies of Robotic Rollators by the User Perspective: A Systematic Review.

    Werner, Christian; Ullrich, Phoebe; Geravand, Milad; Peer, Angelika; Hauer, Klaus

    2016-01-01

    Robotic rollators enhance the basic functions of established devices by technically advanced physical, cognitive, or sensory support to increase autonomy in persons with severe impairment. In the evaluation of such ambient assisted living solutions, both the technical and user perspectives are important to prove usability, effectiveness and safety, and to ensure adequate device application. The aim of this systematic review is to summarize the methodology of studies evaluating robotic rollators with focus on the user perspective and to give recommendations for future evaluation studies. A systematic literature search up to December 31, 2014, was conducted based on the Cochrane Review methodology using the electronic databases PubMed and IEEE Xplore. Articles were selected according to the following inclusion criteria: evaluation studies of robotic rollators documenting human-robot interaction, no case reports, published in English language. Twenty-eight studies were identified that met the predefined inclusion criteria. Large heterogeneity in the definitions of the target user group, study populations, study designs and assessment methods was found across the included studies. No generic methodology to evaluate robotic rollators could be identified. We found major methodological shortcomings related to insufficient sample descriptions and sample sizes, and lack of appropriate, standardized and validated assessment methods. Long-term use in habitual environment was also not evaluated. Apart from the heterogeneity, methodological deficits in most of the identified studies became apparent. Recommendations for future evaluation studies include: clear definition of target user group, adequate selection of subjects, inclusion of other assistive mobility devices for comparison, evaluation of the habitual use of advanced prototypes, adequate assessment strategy with established, standardized and validated methods, and statistical analysis of study results.

    Sheizi Calheira de Freitas

    2016-11-01

    Full Text Available The Brazilian program of higher education evaluation, broadly known as the National Exam of Students’ Performance (ENADE, represents a governmental effort to gather information on undergraduate educational quality. As a product of that evaluation, reports are made available to each program evaluated. Our present research addresses the impact of ENADE evaluation report utilization on multiple higher education accounting programs’ performance in their subsequent evaluation. Based upon theoretical support from literature about evaluation use, a web-based survey was developed and provided across the country to the coordinators of accounting programs. From a response rate of 62% of the study target population and using multiple regressions, we found that there was a positive correlation between usage of the ENADE evaluation report and the performance of undergraduate accounting programs in their subsequent evaluation. Based upon the reviewed literature and, in accordance with these research results, it is possible to infer that the use of evaluation reports derived from the higher education evaluation system promoted by the Brazilian government can influence the decisions of educational institutions and promote improvement.

  1. The methodological quality of economic evaluation studies in obstetrics and gynecology: a systematic review.

    Science.gov (United States)

    Vijgen, Sylvia M C; Opmeer, Brent C; Mol, Ben Willem J

    2013-04-01

    We evaluated the methodological quality of economic evaluation studies in the field of obstetrics and gynecology published in the last decade. A MEDLINE search was performed to find economic evaluation studies in obstetrics and gynecology from the years 1997 through 2009. We included full economic evaluation studies concerning tests or interventions in the field of obstetrics or gynecology. Each included study was evaluated by two reviewers using a quality checklist that was based on international guidelines for medical economic evaluation studies and a checklist used in a previous review. The mean number of quality criteria adhered to was 23 of 30 items, whereas five articles (3%) met all 30 criteria. Compliance was low for the description of the perspective (40%), the completeness of costs looking at the perspective (48%) or time horizon (48%), and reporting of quantities of resources (47%). Furthermore, if no discounting was applied, an explanation was infrequently given (14%). A comparison of study quality to that reported by Smith and Blackmore showed a considerable improvement in the following criteria: presentation perspective (from 19 to 40%), statement of primary outcome measure (from 72 to 81%), completeness costs looking at the time horizon (from 14 to 48%), the presentation of discount rates (from 10 to 54%), details of sensitivity analyses (from 21 to 61%), reporting incremental results (from 17 to 70%), and reporting a summary measure (from 57 to 74%). The quality of economic studies in obstetrics and gynecology has considerably improved in the last decade, but room for further improvement is present.

The method allows flexible and customizable visualization for ISO 13606 archetype based medical data. The chosen evaluation concept is based the Guideline for Good Evaluation Practice in Health Informatics (GEP-HI). The stages of the study were identified. Each stage got a detailed description. We also identified the participants and their required qualifications and responsibilities. The evaluation location was described in details. The evaluation metrics were defined. The questionnaires for doctors, patients and experts were developed to fulfill the requirements of the evaluation study. The study was performed in Tomsk, Russia. 30 patients and 5 doctors participated in the study. The overall performance of the users reached the expert level by the end of the study. Patients as well as medical staff stated in their comments that the usability of the system was high, and they preferred it to the previously used paper-based and computer based systems. This was also shown by the high level of satisfaction measured within our study. The visualization approach, integrated into the electronic health record, was well accepted in our pilot setting with high usability scores from patients and doctors alike. The results showed the efficiency for both modeling and visualization part of the system.

  5. An objective evaluation framework for segmentation techniques of functional positron emission tomography studies

    CERN Document Server

    Kim, J; Eberl, S; Feng, D

    2004-01-01

    Segmentation of multi-dimensional functional positron emission tomography (PET) studies into regions of interest (ROI) exhibiting similar temporal behavior is useful in diagnosis and evaluation of neurological images. Quantitative evaluation plays a crucial role in measuring the segmentation algorithm's performance. Due to the lack of "ground truth" available for evaluating segmentation of clinical images, automated segmentation results are usually compared with manual delineation of structures which is, however, subjective, and is difficult to perform. Alternatively, segmentation of co-registered anatomical images such as magnetic resonance imaging (MRI) can be used as the ground truth to the PET segmentation. However, this is limited to PET studies which have corresponding MRI. In this study, we introduce a framework for the objective and quantitative evaluation of functional PET study segmentation without the need for manual delineation or registration to anatomical images of the patient. The segmentation ...

  9. A study on the performance evaluation of small gamma camera collimators using detective quantun efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Jeon, Ho Sang

    2008-02-15

    The anger-type gamma camera and novel marker compound using Tc-99m were firstly introduced in 1963. The gamma camera systems have being improved and applied to various fields, for example, medical, industrial, and environmental fields. Gamma camera is mainly composed of collimator, detector, and signal processor. And the radiative source is namely the imaging object. The collimator is essential component of gamma camera system because the imaging performance of system is mainly dependent on the collimator. The performance evaluation of collimators can be done by using evaluating factors. In this study, the novel factors for gamma camera evaluation are suggested. The established evaluating factors by NEMA are FWHM, sensitivity, and uniformity. They have some limitations in spite of their usefulness. Firstly, performance evaluation by those factors give insensitive and indirect results only. Secondly, the evaluation of noise property is ambiguous. Thirdly, there is no synthetic evaluation of system performance. Simulation with Monte Carlo code and experiment with a small camera camera were simultaenuously performed to verify novel evaluating factors. For the evaluation of spatial resolution, MTF was applied instead of FWHM. The MTF values presents excellent linear relationship with FWHM values. The NNPS was applied instead of uniformity and sensitivity for the evaluation of noise fluctuation. The NNPS values also presents linear relationship with sensitivity and unifomity. Moreover, these novel factors give quantities as the function of spatial frequencies. Finally, the DQE values were given by calculations with MTF, NNPS, and input SNR. DQE effectively presents the synthetic evaluation of gamma camera performance. It is the conclusion that MTF, NNPS, and DQE can be novel evaluating factors for gamma camera systems and the new factor for synthetic evaluation is derived.

  17. Outcome Reporting Bias in Government-Sponsored Policy Evaluations: A Qualitative Content Analysis of 13 Studies.

    Science.gov (United States)

    Vaganay, Arnaud

    The reporting of evaluation outcomes can be a point of contention between evaluators and policy-makers when a given reform fails to fulfil its promises. Whereas evaluators are required to report outcomes in full, policy-makers have a vested interest in framing these outcomes in a positive light-especially when they previously expressed a commitment to the reform. The current evidence base is limited to a survey of policy evaluators, a study on reporting bias in education research and several studies investigating the influence of industry sponsorship on the reporting of clinical trials. The objective of this study was twofold. Firstly, it aimed to assess the risk of outcome reporting bias (ORB or 'spin') in pilot evaluation reports, using seven indicators developed by clinicians. Secondly, it sought to examine how the government's commitment to a given reform may affect the level of ORB found in the corresponding evaluation report. To answer these questions, 13 evaluation reports were content-analysed, all of which found a non-significant effect of the intervention on its stated primary outcome. These reports were systematically selected from a dataset of 233 pilot and experimental evaluations spanning three policy areas and 13 years of government-commissioned research in the UK. The results show that the risk of ORB is real. Indeed, all studies reviewed here resorted to at least one of the presentational strategies associated with a risk of spin. This study also found a small, negative association between the seniority of the reform's champion and the risk of ORB in the evaluation of that reform. The publication of protocols and the use of reporting guidelines are recommended.

    2014-01-01

    There have been several studies of the neural mechanisms underlying sensation of fatigue. However, little is known about the neural mechanisms underlying self-evaluation of the level of fatigue. The aim of this study was to identify the neural substrates involved in self-evaluation of the level of mental fatigue. We used magnetoencephalography (MEG) with high temporal resolution on 14 healthy participants. During MEG recordings, participants were asked to evaluate their level of mental fatigue in time with execution cues (evaluation trials) or to do nothing in time with execution cues (control trials). The MEG data were analyzed with equivalent current dipole (ECD) and spatial filtering methods to localize the neural activity related to the evaluation of mental fatigue. The daily level of fatigue sensation was assessed using the Checklist Individual Strength questionnaire. In evaluation trials, ECDs were observed in the posterior cingulate cortex (PCC) in seven of 14 participants, with a mean latency of 366.0 ms. The proportion of the participants with ECDs in the PCC was higher in evaluation trials than in control trials (Pfatigue sensation. These data suggest that the PCC and DLPFC are involved in the self-evaluation of mental fatigue.

    With this review, the authors sought to determine what strategies have been evaluated (including the outcomes assessed) to disseminate cancer control interventions that promote the uptake of behavior change. Five topic areas along the cancer care continuum (smoking cessation, healthy diet, mammography, cervical cancer screening, and control of cancer pain) were selected to be representative. A systematic review was conducted of primary studies evaluating dissemination of a cancer control intervention. Thirty-one studies were identified that evaluated dissemination strategies in the 5 topic areas. No strong evidence currently exists to recommend any one dissemination strategy as effective in promoting the uptake of cancer control interventions. The authors conclude that there is a strong need for more research into dissemination of cancer control interventions. Future research should consider methodological issues such as the most appropriate study design and outcomes to be evaluated.

  7. Evaluation of a proposed expert system development methodology: Two case studies

    1990-01-01

    Two expert system development projects were studied to evaluate a proposed Expert Systems Development Methodology (ESDM). The ESDM was developed to provide guidance to managers and technical personnel and serve as a standard in the development of expert systems. It was agreed that the proposed ESDM must be evaluated before it could be adopted; therefore a study was planned for its evaluation. This detailed study is now underway. Before the study began, however, two ongoing projects were selected for a retrospective evaluation. They were the Ranging Equipment Diagnostic Expert System (REDEX) and the Backup Control Mode Analysis and Utility System (BCAUS). Both projects were approximately 1 year into development. Interviews of project personnel were conducted, and the resulting data was used to prepare the retrospective evaluation. Decision models of the two projects were constructed and used to evaluate the completeness and accuracy of key provisions of ESDM. A major conclusion reached from these case studies is that suitability and risk analysis should be required for all AI projects, large and small. Further, the objectives of each stage of development during a project should be selected to reduce the next largest area of risk or uncertainty on the project.

    Expensive and lengthy clinical trials can delay regulatory evaluation and add significant burden that stifles innovation affecting patient access to novel, high-quality imaging technologies. In silico imaging holds promise for evaluating the safety and effectiveness of imaging technologies with much less burden than clinical trials. We define in silico imaging as a computer simulation of an entire imaging system (including source, object, task, and observer components) used for research, development, optimization, technology assessment, and regulatory evaluation of new technology. In this work we describe VICTRE (our study of virtual imaging clinical trials for regulatory evaluation) and the considerations for building an entire imaging pipeline in silico including device (physics), patient (anatomy, disease), and image interpretation models for regulatory evaluation using open-source tools.

    Full Text Available This study was done to evaluate the use of functional measures in hearing aid benefit assessment of children (n = 60 in a rural community. Children with age ranging from 6 months to 15 years with moderately severe to profound hearing loss were evaluated. They were evaluated by functional measures PEACH and TEACH which were translated into local language (Tamil. The relationship between PEACH and TEACH was calculated using SPSS and Chi-square tests. It was found that PEACH and TEACH questionnaires can be easily administered in the rural community and gives a quantitative measure of the effect of amplification. It gave caregivers a motivation to take an active part in the rehabilitation. This model of using functional evaluation tools to evaluate the suitability and effectiveness of amplification can be applied in children in developing countries.

    Zhao, Guangwu; Yang, Linlin; Wang, Jianhua; Zhu, Zhujun

    Since the germination test is still the main method for evaluating seed vigor of sweet corn, it is necessary to study the rapid methods for evaluating their vigor. First, two vigor levels of 9 super sweet corn and 9 sugar enhanced corn hybrids were distinguished by accelerated ageing treatment. Next, their vigor statuses were tested by rapid methods such as electrical conductivity (EC), soluble sugar (SS), volatile aldehyde (VA), dehydrogenase activity (DA) and Q2 oxygen sensing technology. Correlation relationship was analyzed between the above tested values and vigor performances. The results showed that EC, SS, VA, DA, oxygen metabolism rate (OMR), critical oxygen pressure (COP) were all suitable to evaluate seed vigor of sweet corn. Furthermore, VA was optimal for evaluating seed vigor of super sweet corn. DA was optimal for evaluating sugar enhanced corn.

    Full Text Available This paper poses a comparative study among Argentina, Brazil and Uruguay on the research policies adopted in universities and their evaluation. A documentary analysis on current regulations, impact assessments and interviews to key persons enabled to reconstruct the principal aspects of the processes of research development in each country, especially in universities and their evaluation systems. The comparison identifies as a shared feature the difficulties for developing a quality evaluation process which considers the diversity of the systems found in higher education, a heterogeneous characteristic in the three countries.  However, there are differences related to the origin and consolidation of the systems of evaluation of university quality and science and technology, the policies developed in different stages and the influence of the political and economic contexts. These aspects exert a great influence in the different ways to evaluate the function of research, in the national cases as well as their inner ones. 

  14. The neural substrates of physical fatigue sensation to evaluate ourselves: a magnetoencephalography study.

    2014-03-01

    It is important to clarify the neural mechanisms underlying fatigue sensation. There have been several studies which identified brain regions in which the level of the neural activities was correlated with the subjective level of fatigue. However, the neural activity evoked when we evaluate our level of fatigue may not be related to the subjective level of fatigue. Thus, we tried to identify the neural activities caused by the evaluation of the level of fatigue, which may not be related to the subjective level of fatigue. We used magnetoencephalography (MEG) to measure neural activity in 10 healthy participants enrolled in our study. During MEG recordings, participants were asked to evaluate the level of physical fatigue in their right hand in time with execution cues (evaluation session) or to direct attention to their right hand in time with execution cues (control session). Equivalent current dipole (ECD) analysis was performed to localize the neural activity limited to the evaluation session. In the evaluation session, ECDs with mean latencies of approximately 380ms were observed in nine of 10 participants. These were localized in the posterior cingulate cortex (PCC), while in the control session, the ECDs in the same brain region were observed in only two of 10 participants. The proportion of participants in whom ECDs were observed in the PCC in the evaluation session was significantly higher than that in the control session (McNemar test). In addition, the intensities of the ECDs were positively associated with the extent to which the participants successfully evaluated the fatigue in their right hand in the evaluation session. These data suggest that the PCC is involved in the neural substrates associated with self-evaluation of physical fatigue.

  15. An Orchestrating Evaluation of Complex Educational Technologies: a Case Study of a CSCL System

    Directory of Open Access Journals (Sweden)

    Luis P. Prieto

    2014-06-01

    Full Text Available As digital technologies permeate every aspect of our lives, the complexity of the educational settings, and of the technological support we use within them, unceasingly rises. This increased complexity, along with the need for educational practitioners to apply such technologies within multi-constraint authentic settings, has given rise to the notion of technology-enhanced learning practice as “orchestration of learning”. However, at the same time, the complexity involved in evaluating the benefits of such educational technologies has also increased, prompting questions about the way evaluators can cope with the different places, technologies, informants and issues involved in their evaluation activity. By proposing the notion of “orchestrating evaluation”, this paper tries to reconcile the often disparate “front office accounts” of research publications and the “shop floor practice” of evaluation of educational technology, through the case study of evaluating a system to help teachers in coordinating computer-supported collaborative learning (CSCL scenarios. We reuse an internationally-evaluated conceptual framework of “orchestration aspects” (design, management, adaptation, pragmatism, etc. to structure the case‟s narrative, showing how the original evaluation questions and methods were modulated in the face of the multiple (authentic evaluation setting constraints.

  16. [The external evaluation of study quality: the role in maintaining the reliability of laboratory information].

    Men'shikov, V V

    2013-08-01

    The external evaluation of quality of clinical laboratory examinations was gradually introduced in USSR medical laboratories since 1970s. In Russia, in the middle of 1990 a unified all-national system of external evaluation quality was organized known as the Federal center of external evaluation of quality at the basis of laboratory of the state research center of preventive medicine. The main positions of policy in this area were neatly formulated in the guidance documents of ministry of Health. Nowadays, the center of external evaluation of quality proposes 100 and more types of control studies and permanently extends their specter starting from interests of different disciplines of clinical medicine. The consistent participation of laboratories in the cycles of external evaluation of quality intrinsically promotes improvement of indicators of properness and precision of analysis results and increases reliability of laboratory information. However, a significant percentage of laboratories does not participate at all in external evaluation of quality or takes part in control process irregularly and in limited number of tests. The managers of a number of medical organizations disregard the application of the proposed possibilities to increase reliability of laboratory information and limit financing of studies in the field of quality control. The article proposes to adopt the national standard on the basis of ISO 17043 "Evaluation of compliance. The common requirements of professional competence testing".

    2016-01-01

    Introduction Online education resources (OERs), like blogs and podcasts, increasingly augment or replace traditional medical education resources such as textbooks and lectures. Trainees’ ability to evaluate these resources is poor, and few quality assessment aids have been developed to assist them. This study aimed to derive a quality evaluation instrument for this purpose. Methods We used a three-phase methodology. In Phase 1, a previously derived list of 151 OER quality indicators was reduced to 13 items using data from published consensus-building studies (of medical educators, expert podcasters, and expert bloggers) and subsequent evaluation by our team. In Phase 2, these 13 items were converted to seven-point Likert scales used by trainee raters (n=40) to evaluate 39 OERs. The reliability and usability of these 13 rating items was determined using responses from trainee raters, and top items were used to create two OER quality evaluation instruments. In Phase 3, these instruments were compared to an external certification process (the ALiEM AIR certification) and the gestalt evaluation of the same 39 blog posts by 20 faculty educators. Results Two quality-evaluation instruments were derived with fair inter-rater reliability: the METRIQ-8 Score (Inter class correlation coefficient [ICC]=0.30, pgestalt (Pearson’s r=0.35, p=0.03 and r=0.41, pgestalt ratings of online educational resources by faculty educators. Further testing is needed to ensure these instruments are accurate when applied by trainees. PMID:27625722

    Mende-Siedlecki, Peter; Said, Christopher P; Todorov, Alexander

    2013-03-01

    Neuroscience research on the social evaluation of faces has accumulated over the last decade, yielding divergent results. We used a meta-analytic technique, multi-level kernel density analysis (MKDA), to analyze 29 neuroimaging studies on face evaluation. Across negative face evaluations, we observed the most consistent activations in bilateral amygdala. Across positive face evaluations, we observed the most consistent activations in medial prefrontal cortex, pregenual anterior cingulate cortex (pgACC), medial orbitofrontal cortex (mOFC), left caudate and nucleus accumbens (NAcc). Based on additional analyses comparing linear and non-linear responses, we propose a ventral/dorsal dissociation within the amygdala, wherein separate populations of neurons code for face valence and intensity, respectively. Finally, we argue that some of the differences between studies are attributable to differences in the typicality of face stimuli. Specifically, extremely attractive faces are more likely to elicit responses in NAcc/caudate and mOFC.

    2006-08-01

    Full Text Available From 1932 to 1940, the Progressive Education Association (PEA conducted its Eight-Year Study. At first, the study appeared to be a poorly funded comparison of two groups of students in secondary schools. During the last four years, as more financial support became available, the Eight-Year Study became a broadly based demonstration of a wide range of educational innovations. For contemporary educators, the story of the Eight-Year Study represents an opportunity to reconsider popular principles of program evaluation such as utilization-focused evaluation or program theory in evaluation. Rather than set plans in advance, the PEA members seemed to follow the ideas of John Dewey; they allowed the purposes to widen and broaden as the study evolved. In this way, the Eight-Year Study represented a model of democratic policy evaluation. Its tentative type of planning allowed people to set and to change their own purposes in line with the needs of the wider organization. Part of the reason that the study changed direction was it gathered more financial support and could add consultants who worked in distinct program elements. In addition, the lack of consistency matched the varied nature that characterized the founding members of the PEA. Its democratic framework may have enabled the Eight-Year Study to become the PEA’s abiding contribution to American education.

    Full Text Available The need for distance education is increasing due to such reasons as keeping up with the changing social conditions, meeting the learning needs of the individuals and enabling them to be lifelong learners. In addition to many advantages distance education provides, it also has certain restrictions. One of these restrictions is the problems encountered in evaluating students’ success and performance. The purpose of this study is to examine the viewpoints of lecturers regarding the evaluation process of academic success and performance of those students who are attending to online distance education program and to compare lecturers’ views on assessment and evaluation practices carried out in face-to-face classroom environment with those online assessment and evaluation practices. The study was a case study and the data of the study were collected from the lecturers who lectured in a distant education program of a state university. Based on the findings of the study, the problems that lecturers have in evaluating the success and performance of the students in online distance education and possible solution suggestions for these problems are presented.

  5. Pose Estimation with a Kinect for Ergonomic Studies: Evaluation of the Accuracy Using a Virtual Mannequin

    2015-01-01

    Full Text Available Analyzing human poses with a Kinect is a promising method to evaluate potentials risks of musculoskeletal disorders at workstations. In ecological situations, complex 3D poses and constraints imposed by the environment make it difficult to obtain reliable kinematic information. Thus, being able to predict the potential accuracy of the measurement for such complex 3D poses and sensor placements is challenging in classical experimental setups. To tackle this problem, we propose a new evaluation method based on a virtual mannequin. In this study, we apply this method to the evaluation of joint positions (shoulder, elbow, and wrist, joint angles (shoulder and elbow, and the corresponding RULA (a popular ergonomics assessment grid upper-limb score for a large set of poses and sensor placements. Thanks to this evaluation method, more than 500,000 configurations have been automatically tested, which would be almost impossible to evaluate with classical protocols. The results show that the kinematic information obtained by the Kinect software is generally accurate enough to fill in ergonomic assessment grids. However inaccuracy strongly increases for some specific poses and sensor positions. Using this evaluation method enabled us to report configurations that could lead to these high inaccuracies. As a supplementary material, we provide a software tool to help designers to evaluate the expected accuracy of this sensor for a set of upper-limb configurations. Results obtained with the virtual mannequin are in accordance with those obtained from a real subject for a limited set of poses and sensor placements.

    Although evaluation is now an integral part of the design and implementation of public programs in many countries, there is growing recognition that the utilization of evaluation results for improving implementation and decision making, particularly in developing countries, is limited. The objective of this paper is to describe the process by which the external impact evaluation has been used to increase the potential of Oportunidades to improve nutritional outcomes of the beneficiary population through modifications to its design and operation. We will summarize a series of studies that have guided this process and focus on key aspects that have facilitated the utilization of evaluation results for decision making in the program. Implementation of research to document the impact of programs and the publication of such findings in peer reviewed journals, although vital for improving our evidence base and for the advancement of researchers within the current academic system, is not enough to ensure that the program itself will benefit from the evaluation. The use of evaluation results as a basis for modifications to the design and implementation of the nutrition component of Oportunidades was favored by open dialogue among all sectors involved in the program and the evaluation team and a long-term commitment on the part of all those involved. We think that the lessons learnt from this process are relevant for other programs, even where resources may be limited.

    Full Text Available Rapid developments in retailing sector bring about some ethical problems. Retailing is a faceto-face marketing activity by its nature. Thus, ethical problems in retailing directly affect consumers and consumer reactions turn directly to retailers. Therefore, defining and solving the ethical problems in retailing is an important issue for retailers. The main purpose of this study is to identify the food and clothing retailers’ perspective about ethical purchase decision making process and their evaluations on this subject. Beside this, identifying the differences of these evaluations in terms of the demographic characteristics of retailers is another objective of this study. Findings show that retailers generally approve ethical behaviors and disapprove unethical behaviors. In addition, evaluations of retailers differ in terms of some demographic characteristics. Results of the study also show that retailers are sensitive about unethical actions and behaviors and they believe that all the retailers must act according to ethical principles.

    Full Text Available Introduction: The subject of beauty has been the topic of much debate throughout history, and methods for the evaluation of beauty have been the focus of many research projects. The evaluation of beauty is influenced by factors which include various linear measurements, angles, ratios, and proportions. We evaluated several ratios in Indian Population after locating various landmarks on beautiful Indian faces. Aims and Objectives: The aim of the present study was to evaluate various facial proportions of Indian beauties using their frontal photographs in natural head position to establish anthropometric norms in beautiful Indian females. To evaluate whether these values satisfy golden and silver proportions. To compare these values with Caucasian anthropometric norms. Materials and Methods: Frontal photographs of 30 female celebrities were downloaded from the internet. Photographs of only those Indian beauties that have been declared winners of either national or international beauty contests by a designated panel of judges were included in this study. Hardcopy of these photographs was taken in 5 inch by 3.5 inch format, all the measurements done and ratios calculated. Results: Measurements were tabulated and values for various ratios were calculated to establish norms. Coefficient of variation was also evaluated. Conclusion: All the ratios were found to be consistent than others which made it possible to assess beauty objectively rather than arbitrarily. Most of the values did not match the golden and silver proportion. In comparison with Caucasian population, we found that there is significant difference in most of the values.

    Breast cancer is globally a major threat for women's health. Screening and adequate follow-up can significantly reduce the mortality from breast cancer. Human second reading of screening mammograms can increase breast cancer detection rates, whereas this has not been proven for current computer-aided detection systems as "second reader". Critical factors include the detection accuracy of the systems and the screening experience and training of the radiologist with the system. When assessing the performance of systems and system components, the choice of evaluation methods is particularly critical. Core assets herein are reference image databases and statistical methods. We have analyzed characteristics and usage of the currently largest publicly available mammography database, the Digital Database for Screening Mammography (DDSM) from the University of South Florida, in literature indexed in Medline, IEEE Xplore, SpringerLink, and SPIE, with respect to type of computer-aided diagnosis (CAD) (detection, CADe, or diagnostics, CADx), selection of database subsets, choice of evaluation method, and quality of descriptions. 59 publications presenting 106 evaluation studies met our selection criteria. In 54 studies (50.9%), the selection of test items (cases, images, regions of interest) extracted from the DDSM was not reproducible. Only 2 CADx studies, not any CADe studies, used the entire DDSM. The number of test items varies from 100 to 6000. Different statistical evaluation methods are chosen. Most common are train/test (34.9% of the studies), leave-one-out (23.6%), and N-fold cross-validation (18.9%). Database-related terminology tends to be imprecise or ambiguous, especially regarding the term "case". Overall, both the use of the DDSM as data source for evaluation of mammography CAD systems, and the application of statistical evaluation methods were found highly diverse. Results reported from different studies are therefore hardly comparable. Drawbacks of the DDSM

    Abstract Background  Public involvement is central to health and social research policies, yet few systematic evaluations of its impact have been carried out, raising questions about the feasibility of evaluating the impact of public involvement. Objective  To investigate whether it is feasible to evaluate the impact of public involvement on health and social research. Methods  Mixed methods including a two‐round Delphi study with pre‐specified 80% consensus criterion, with follow‐up interviews. UK and international panellists came from different settings, including universities, health and social care institutions and charitable organizations. They comprised researchers, members of the public, research managers, commissioners and policy makers, self‐selected as having knowledge and/or experience of public involvement in health and/or social research; 124 completed both rounds of the Delphi process. A purposive sample of 14 panellists was interviewed. Results  Consensus was reached that it is feasible to evaluate the impact of public involvement on 5 of 16 impact issues: identifying and prioritizing research topics, disseminating research findings and on key stakeholders. Qualitative analysis revealed the complexities of evaluating a process that is subjective and socially constructed. While many panellists believed that it is morally right to involve the public in research, they also considered that it is appropriate to evaluate the impact of public involvement. Conclusions  This study found consensus among panellists that it is feasible to evaluate the impact of public involvement on some research processes, outcomes and on key stakeholders. The value of public involvement and the importance of evaluating its impact were endorsed. PMID:21324054

    Solbrig, Harold R; Chute, Christopher G

    2012-01-01

    Objective The objective of this study is to develop an approach to evaluate the quality of terminological annotations on the value set (ie, enumerated value domain) components of the common data elements (CDEs) in the context of clinical research using both unified medical language system (UMLS) semantic types and groups. Materials and methods The CDEs of the National Cancer Institute (NCI) Cancer Data Standards Repository, the NCI Thesaurus (NCIt) concepts and the UMLS semantic network were integrated using a semantic web-based framework for a SPARQL-enabled evaluation. First, the set of CDE-permissible values with corresponding meanings in external controlled terminologies were isolated. The corresponding value meanings were then evaluated against their NCI- or UMLS-generated semantic network mapping to determine whether all of the meanings fell within the same semantic group. Results Of the enumerated CDEs in the Cancer Data Standards Repository, 3093 (26.2%) had elements drawn from more than one UMLS semantic group. A random sample (n=100) of this set of elements indicated that 17% of them were likely to have been misclassified. Discussion The use of existing semantic web tools can support a high-throughput mechanism for evaluating the quality of large CDE collections. This study demonstrates that the involvement of multiple semantic groups in an enumerated value domain of a CDE is an effective anchor to trigger an auditing point for quality evaluation activities. Conclusion This approach produces a useful quality assurance mechanism for a clinical study CDE repository. PMID:22511016

    Full Text Available Abstract Background There is a global need to assess physicians' professional performance in actual clinical practice. Valid and reliable instruments are necessary to support these efforts. This study focuses on the reliability and validity, the influences of some sociodemographic biasing factors, associations between self and other evaluations, and the number of evaluations needed for reliable assessment of a physician based on the three instruments used for the multisource assessment of physicians' professional performance in the Netherlands. Methods This observational validation study of three instruments underlying multisource feedback (MSF was set in 26 non-academic hospitals in the Netherlands. In total, 146 hospital-based physicians took part in the study. Each physician's professional performance was assessed by peers (physician colleagues, co-workers (including nurses, secretary assistants and other healthcare professionals and patients. Physicians also completed a self-evaluation. Ratings of 864 peers, 894 co-workers and 1960 patients on MSF were available. We used principal components analysis and methods of classical test theory to evaluate the factor structure, reliability and validity of instruments. We used Pearson's correlation coefficient and linear mixed models to address other objectives. Results The peer, co-worker and patient instruments respectively had six factors, three factors and one factor with high internal consistencies (Cronbach's alpha 0.95 - 0.96. It appeared that only 2 percent of variance in the mean ratings could be attributed to biasing factors. Self-ratings were not correlated with peer, co-worker or patient ratings. However, ratings of peers, co-workers and patients were correlated. Five peer evaluations, five co-worker evaluations and 11 patient evaluations are required to achieve reliable results (reliability coefficient ≥ 0.70. Conclusions The study demonstrated that the three MSF instruments produced

    The use of new technology has recently grown considerably as an increasing number of college students using Internet. In nursing education, the personal computer and the Internet facilitate teaching theoretical and practical knowledge. Evaluate an educational technology known as "Anatomy and Vital Signs" with respect to content, appearance and usability. This was a first stage evaluation-by specialists to verify content and functioning, prior to a second validation as to learning by students. A methodological study in which instructional technologists (11 participants) and nursing specialists (17 participants) used the technology in an unguided manner and completed three questionnaires. The evaluation was measured by the difference between disagreement and agreement for each statement in the questionnaires. Most of the items were positively evaluated at a level higher than 70% by most of the evaluators except for the following usability criteria: grouping by shape, minimum actions and user control, which did not attain the 70% agreement level among instructional technologists. The evaluation was useful to improve the technology and guarantee suitable product for nursing education. It may be a reliable educational tool for nursing education that applies technological resources. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Assessing clinical competence in nursing students abroad is a challenge, and requires both methods and instruments capable of capturing the multidimensional nature of the clinical competences acquired. The aim of the study was to compare the clinical competence assessment processes and instruments adopted for nursing students during their clinical placement abroad. A case study design was adopted in 2015. A purposeful sample of eight nursing programmes located in seven countries (Belgium, Denmark, Greece, Norway, Poland, Portugal and Italy) were approached. Tools as instruments for evaluating competences developed in clinical training by international nursing students, and written procedures aimed at guiding the evaluation process, were scrutinised through a content analysis method. All clinical competence evaluation procedures and instruments used in the nursing programmes involved were provided in English. A final evaluation of the competences was expected by all nursing programmes at the end of the clinical placement, while only four provided an intermediate evaluation. Great variability emerged in the tools, with between five and 88 items included. Through content analysis, 196 items emerged, classified into 12 different core competence categories, the majority were categorised as 'Technical skills' (=60), 'Self-learning and critical thinking' (=27) and 'Nursing care process' (=25) competences. Little emphasis was given in the tools to competences involving 'Self-adaptation', 'Inter-professional skills', 'Clinical documentation', 'Managing nursing care', 'Patient communication', and 'Theory and practice integration'. Institutions signing Bilateral Agreements should agree upon the competences expected from students during their clinical education abroad. The tools used in the process, as well as the role expected by the student, should also be agreed upon. Intercultural competences should be further addressed in the process of evaluation, in addition to

    2016-02-01

    The Society of Toxicologic Pathology formed a working group in collaboration with the American Society for Veterinary Clinical Pathology to provide recommendations for the appropriate inclusion of clinical pathology evaluation in recovery arms of nonclinical toxicity studies but not on when to perform recovery studies. Evaluation of the recovery of clinical pathology findings is not required routinely but provides useful information on risk assessment in nonclinical toxicity studies and is recommended when the ability of the organ to recover is uncertain. The study design generally requires inclusion of concurrent controls to separate procedure-related changes from test article-related changes, but return of clinical pathology values toward baseline may be sufficient in some cases. Evaluation of either a select or full panel of standard hematology, coagulation, and serum and urine chemistry biomarkers can be scientifically justified. It is also acceptable to redesignate dosing phase animals to the recovery phase or vice versa to optimize data interpretation. Assessment of delayed toxicity during the recovery phase is not required but may be appropriate in development programs with unique concerns. Evaluation of the recovery of clinical pathology data for vaccine development is required and, for efficacy markers, is recommended if it furthers pharmacologic understanding.

    2016-07-01

    Nursing education is challenged to prepare students for complex healthcare needs through the integration of teamwork and informatics. Technology has become an important teaching tool in the blended classroom to enhance group based learning experiences. Faculty evaluation of classroom technologies is imperative prior to adoption. Few studies have directly compared various technologies and their impact on student satisfaction and learning. The purpose of this study was to evaluate technology enhanced teaching methods on the learning and satisfaction of graduate students in an advanced pharmacology class using an unfolding case study. After IRB approval, students were randomly assigned to one of three groups: blogging group, wiki group or webinar group. Students completed the evolving case study using the assigned interactive technology. Student names were removed from the case studies. Faculty evaluated the case study using a rubric, while blinded to the assigned technology method used. No significant difference was found on case study grades, the range of grades on the assignment demonstrated little differences between the methods used. Students indicated an overall positive impact related to networking and collaboration on a satisfaction survey. Impact of technology methods needs to be explored in other areas of graduate nursing education.

    Patient satisfaction is an important goal in complete denture therapy, and many factors influence this parameter. This study aimed to evaluate expectations before and satisfaction after therapy with complete dentures. As a secondary objective, other variables that may interfere with patient satisfaction were also evaluated. A representative sample of 99 patients assigned visual analog scale (VAS) scores to their expectations before and satisfaction after therapy regarding chewing, esthetics, comfort, and phonetics. Demographic data and answers to a questionnaire concerning the dentists' conduct were recorded. Multiple linear regression was used to evaluate the association among studied variables and patients' expectation and satisfaction with their dentures. The average VAS scores were high for both expectations and satisfaction, and satisfaction exceeded expectations. Patients' expectations about esthetics and comfort were associated with age and self-reported time of using complete dentures. Patient satisfaction regarding chewing was associated with the number of postdelivery adjustments. Also, patient satisfaction regarding esthetics was associated with gender and esthetic expectations. In regard to phonetic satisfaction, associations were verified among self-reported time of using complete dentures, comfort and phonetics expectations, and dentists' explanations. Comfort satisfaction was associated only with educational level. Patient satisfaction regarding complete dentures exceeded expectations and an expressive majority of positive evaluations of the dentists was noticed. Many patient-related variables seemed to influence their evaluations of their dentures. © 2015 by the American College of Prosthodontists.

    Full Text Available Objectives: The identity of a person can be established by assessing one′s age, and in order to be entitled to civil rights and social benefits, verification of the chronological age is required and thereby age estimation has gained an increasing significance in recent years. Tooth eruption is one of the criteria of developmental morphology that can be evaluated by either clinical examination or by evaluation of dental radiographs to determine the dental age. The present study was aimed to evaluate the reliability of the third molar eruption stage as a parameter for forensic age estimation in living subjects. Materials and Methods: The stage of wisdom tooth eruption in 77 male and 73 female Indian subjects aged between 12-26 years was determined by subjecting them to conventional orthopantomograms and was interpreted to assess the third molar eruption stages to evaluate the dental age. Results: Predicted minimum age and mean age of the study sample were found to be significant predictors (P<0.001 of actual age. Minimum age was able to explain 58.3% of the variation in actual age and the mean age was able to explain 60.3% of variation in actual age. Conclusion: Third molar is fairly a reliable indicator to determine the age of alveolar, gingival, and complete emergence of third molar in the occlusal plane in adolescents and young adults. Minimum and most probable ages of examined subjects can also be evaluated using third molar eruption stage.

    2015-01-01

    The objective of this paper is to provide considerations based on comprehensive case studies important for regulatory evaluation of monoclonal antibodies as similar biotherapeutic products (SBPs) with a special emphasis on clinical aspects. Scientific principles from WHO Guidelines on SBPs were used as a basis for the exercise. Working groups consisted of regulators, manufacturers and academia. The following topics were discussed by the working groups: clinical criteria for biosimilarity, extrapolation approach and the overall regulatory decision making process. In order to determine typical pitfalls in the design of a SBP clinical programme and evaluate the gap of knowledge, amongst different industry and regulatory stakeholders on the appraisal of the data arising from SBP clinical studies, we have presented two fictional but realistic clinical case studies. The first case consists of the fictional development programme for an infliximab SBP candidate. The second case describes clinical studies proposed for a fictional rituximab SBP candidate. In the first scenario a highly similar quality profile has been taken forward into clinical studies whereas there was an important residual difference in functional attributes for the rituximab SBP candidate. These case studies were presented at the WHO implementation workshop for the WHO guidelines on evaluation of similar biotherapeutic products held in Seoul, Republic of Korea, in May 2014. The goal was to illustrate the interpretation of the clinical data arising from studies with SBP candidates and elicit knowledge gaps in clinical assessment. This paper reflects the outcome of the exercise and discussions held in Seoul and offers an analysis of the case studies as a learning opportunity on clinical development and evaluation of SBPs.

    In this paper, IT Industry's innovation capability is considered to be the innovation output capability after complex operation of industry input in industry system. In this complex process, R&D personnel input and R&D expense input are un-substitutable, and for evaluation of innovation capability, innovation input and innovation output also are un-substitutable. Based on this theory, an evaluation model of sustaining strength index is put forward. Considering both input scale and output contribution of IT industry's innovation system, this model reflects the un-substitutability of every evaluation aspects. The measurement result not only shows the industry innovation capability, but also reflects the support degree to economy. At last the data of IT industry in China are provided between 1994 and 2004 for empirical study.

    Full Text Available The evaluation of the hidden economy involves major difficulties related to the use of an adequate methodology and to ensuring the necessary database for estimating some econometric models and some economic variables. The studies conducted showed that the size and forms of the informal economy differ from one country to another. The transition from the economies of the former socialist countries led to an increase in the size of the hidden economy. The highest levels are recorded in some former Soviet republics and in some South American countries. The evaluations made at the level of Romania estimated that the hidden economy accounts for approximately 30% of the Gross Domestic Product. This paper evaluates the size of the hidden economy on the basis of an econometric approach which assesses the cash outside the banking system according to various factors and to its use in official and hidden economy transactions.

    Non-clinical studies are necessary at each stage of the development of oncology drugs. Many experimental cancer models have been developed to investigate carcinogenesis, cancer progression, metastasis, and other aspects in cancer biology and these models turned out to be useful in the efficacy evaluation and the safety prediction of oncology drugs. While the diversity and the degree of engagement in genetic changes in the initiation of cancer cell growth and progression are widely accepted, it has become increasingly clear that the roles of host cells, tissue microenvironment, and the immune system also play important roles in cancer. Therefore, the methods used to develop oncology drugs should continuously be revised based on the advances in our understanding of cancer. In this review, we extensively summarize the effective use of those models, their advantages and disadvantages, ranges to be evaluated and limitations of the models currently used for the development and for the evaluation of oncology drugs.

    The variation in hardness of enamel is a frequently used method to evaluate the influence of whiting materials on the enamel. The purpose of this study is to improve the veracity on the evaluation tests caused by the tooth itself with point selection method. Three kinds of testing point selection methods on enamel were carried out, i. e. random selection, grid measurement and symmetrical measurement, respectively. The selected points were used to measure the micro hardness by Vickers. The influence of the variation of tooth structure itself on the hardness measurements results can be reduced by using testing point selection methods of symmetry, and thus, the accuracy of the test method used in the evaluation of the influence of dental materials on tooth hardness will be guaranteed.

    2016-01-01

    Background Studies have found that marginalized groups living in deprived neighborhoods are less likely to participate in health programs compared to the majority of society. This study evaluates recruitment approaches conducted during a national government-funded project in 12 deprived neighborhoods across Denmark between 2010 and 2014. The aim of this study was to understand how recruitment approaches could promote participation in health programs within deprived neighborhoods to reach marginalized groups. Method Documents from all 12 of the included municipalities were collected to conduct a document evaluation. The collected documents consisted of 1,500 pages of written material with 12 project descriptions, three midterm and 10 final evaluations. The collected data were analyzed through a qualitative content analysis. Results The results are based on the fact that only 10 municipalities have developed evaluations related to recruitment, and only three evaluations provided a description of which marginalized groups were recruited. Challenges related to recruitment consist of difficulties involving the target group, including general distrust, language barriers and a lack of ability to cope with new situations and strangers. Additional geographical challenges emerged, especially in rural areas. Positive experiences with recruitment approaches were mainly related to relationship building and trust building, especially through face-to-face contact and the project employees’ presence in the neighborhood. Additionally, adjusting some of the interventions and the recruitment strategy increased participation. Conclusion This study found that relation and trust between the residents and the project employees is an important factor in the recruitment of marginalized groups in deprived neighborhoods as well as adjusting the health interventions or recruitment strategy to the target groups. In future research, it is necessary to examine which recruitment approaches are

    In healthcare change interventions, on-the-ground learning about the implementation process is often lost because of a primary focus on outcome improvements. This paper describes the Learning Evaluation, a methodological approach that blends quality improvement and implementation research methods to study healthcare innovations. Learning Evaluation is an approach to multi-organization assessment. Qualitative and quantitative data are collected to conduct real-time assessment of implementation processes while also assessing changes in context, facilitating quality improvement using run charts and audit and feedback, and generating transportable lessons. Five principles are the foundation of this approach: (1) gather data to describe changes made by healthcare organizations and how changes are implemented; (2) collect process and outcome data relevant to healthcare organizations and to the research team; (3) assess multi-level contextual factors that affect implementation, process, outcome, and transportability; (4) assist healthcare organizations in using data for continuous quality improvement; and (5) operationalize common measurement strategies to generate transportable results. Learning Evaluation principles are applied across organizations by the following: (1) establishing a detailed understanding of the baseline implementation plan; (2) identifying target populations and tracking relevant process measures; (3) collecting and analyzing real-time quantitative and qualitative data on important contextual factors; (4) synthesizing data and emerging findings and sharing with stakeholders on an ongoing basis; and (5) harmonizing and fostering learning from process and outcome data. Application to a multi-site program focused on primary care and behavioral health integration shows the feasibility and utility of Learning Evaluation for generating real-time insights into evolving implementation processes. Learning Evaluation generates systematic and rigorous cross

    Full Text Available Some new Schiff bases of 4-aminopyridine were synthesized and evaluated for antiamnesic and cognition enhancing activity. In the current study to further understand the mechanism of action of these derivatives we have evaluated in-vitro acetycholinesterase (AChE and butyrylcholinesterase (BChE inhibitory activity. Enzyme kinetics and docking studies were performed for all compounds to observe their nature of inhibition. The IC50 value of synthesized compounds showed maximum activity of compound 4APg compared to standard drug donepezil and rivastigmine whereas its kinetic analysis of enzyme inhibition demonstrated non-competitive inhibition for both enzymes AChE and BChE. The docking study confirmed their consensual interaction with AChE and BChE active sites justifying the experimental outcome.

    Full Text Available OBJECTIVE: This study aimed to compare the pelvic floor muscle strength of nulliparous and primiparous women. METHODS: A total of 100 women were prospectively distributed into two groups: Group 1 (G1 (n = 50 included healthy nulliparous women, and Group 2 (G2 (n = 50 included healthy primiparous women. Pelvic floor muscle strength was subjectively evaluated using transvaginal digital palpation. Pelvic floor muscle strength was objectively assessed using a portable perineometer. All of the parameters were evaluated simultaneously in G1 and were evaluated in G2 during the 20th and 36th weeks of pregnancy and 45 days after delivery. RESULTS: In G2, 14 women were excluded because they left the study before the follow-up evaluation. The median age was 23 years in G1 and 22 years in G2; there was no significant difference between the groups. The average body mass index was 21.7 kg/m² in G1 and 25.0 kg/m² in G2; there was a significant difference between the groups (p = 0.0004. In G2, transvaginal digital palpation evaluation showed significant impairments of pelvic floor muscle strength at the 36th week of pregnancy (p = 0.0006 and 45 days after vaginal delivery (p = 0.0001 compared to G1. Objective evaluations of pelvic floor muscle strength in G2 revealed a significant decrease 45 days after vaginal delivery compared to nulliparous patients. CONCLUSION: Pregnancy and vaginal delivery may cause weakness of the pelvic floor muscles.

    Headache is a common complaint in children occasionally requiring hospital admission. The purposes of the present study were to analyze the prevalence of uncorrected ametropia in children with headache admitted to the hospital, and evaluate the importance of refraction assessment as part of their evaluation. A retrospective review of children admitted to the Tel Aviv Medical Center for headache evaluation from December 2008 to March 2013, in whom the only abnormality found was an uncorrected refractive error. During the study period 917 children with headache were hospitalized for evaluation and 16 (1.7%) of them (9 boys, mean age 12 years, range 8-18 years) were found to have an uncorrected ametropia. Average headache duration was 4 months (range, 1 week to 1 year) and mean follow-up was 15 months (range, 1 month to 3 years). Twelve (75%) children had brain imaging and 4 children (25%) had a lumbar puncture before their refractive abnormality was identified. Anisometropia and myopia were the most common refractive errors encountered (n = 10 each), followed by hyperopia (n = 6) and astigmatism (n = 3). Despite having uncorrected refractive errors most children (n = 10) did not complain of any visual difficulty. All children were given proper refractive correction and 14 of them reported complete headache resolution on re-examination one month later. Uncorrected ametropia is a possible cause of headache among hospitalized children. Therefore, complete ophthalmic evaluation, which includes proper refraction assessment, is important as it can identify a treatable headache etiology. Children without visual difficulty should be equally evaluated, as many children with headache and uncorrected amteropia do not have vision complaints.

    Introduction: The aim of this study was to compare several metallurgic properties of Neoniti instrument with four other commonly used endodontic rotary files. Methods and Materials: Neoniti A1 (25/0.08), RaCe (25/0.06), Mtwo (25/0.06), Twisted file (25/0.06) and ProTaper Next X2 (25/0.06) were examined by differential scanning calorimetry (DSC) before and after heat treatment at 500°C. X-ray diffraction (XRD) was also performed on the specimens. Furthermore, scanning electron microscopy (SEM) and x-ray energy-dispersive spectrometric (EDS) analyses were carried out on randomly selected fractured files. Results: In SEM tests, dimpled ruptures, characteristic of ductile fracture, were seen in all evaluated cross sections of all files. The SEM results of all evaluated files were alike. EDS results revealed higher proportions of Nickel (Ni) rich intermetallic compounds in Neoniti; whereas, in all the other files the proportion of Titanium (Ti) rich precipitates was higher. DSC results indicated that the temperature present in the oral environment, the austenite phase existed in all files. Mtwo and RaCe files did not show austenite transformation in the temperature range evaluated in this study. Only Neoniti revealed rhombohedal phase (R-phase) transformation. After heat treatment. No significant difference was seen in the transformation temperatures of all evaluated files. XRD evaluations revealed that Neoniti contained both Ni-rich and Ti-rich precipitates. The amount of the martensite phase was higher in ProTaper Next. Conclusion: The metallurgic properties of Neoniti files were different from other evaluated rotary files. This file contained higher proportions of Ni-rich precipitates. PMID:27790257

    A systematic classification of study designs would be useful for researchers, systematic reviewers, readers, and research administrators, among others. As part of the Human Studies Database Project, we developed the Study Design Typology to standardize the classification of study designs in human research. We then performed a multiple observer masked evaluation of active research protocols in four institutions according to a standardized protocol. Thirty-five protocols were classified by three reviewers each into one of nine high-level study designs for interventional and observational research (e.g., N-of-1, Parallel Group, Case Crossover). Rater classification agreement was moderately high for the 35 protocols (Fleiss' kappa = 0.442) and higher still for the 23 quantitative studies (Fleiss' kappa = 0.463). We conclude that our typology shows initial promise for reliably distinguishing study design types for quantitative human research.

    Full Text Available As Maloney and Ward (1973 noted thirty eight years ago, “determining what the population knows regarding ecology, the environment and pollution; how they feel about it; what commitments they are willing to make and what commitments they do make are necessary steps that must be made before adopting any strategy that modifies behaviour and habits”. Taking into account that Romania is facing a great challenge to bring its waste management system in line with EU Directives and the key role of education in this process, the paper aims to explore through a questionnaire based survey: (1 the level of knowledge and awareness regarding municipal waste among students, their attitudes and willingness to act in waste related activities, (2 if there are significant differences regarding students awareness, knowledge and concern according to their gender, age, affiliation (faculty or job status. The paper is structured in four parts, namely: introduction, research methodology, results analysis and conclusions. The findings of this research study showed that the majority of students are generally aware of waste problems. It is important to note, however, that many respondents called for more information, frequent updates and reminders about waste management practices. Pro-environmental and recycling attitudes were shown to be generally positive among students from BAES. Used in the right way such findings might be essential in achieving the overall goal of improving waste management systems, whether it is a recycling scheme, composting scheme or refers to the improvement of environmental awareness process.

    Purpose: The aim of this work was to analyse all the applied movements when extracting healthy upper and lower jaw premolars for orthodontic purposes. The authors wanted to demonstrate that the different bone densities of the mandible and maxilla are not a significant parameter when related to the extraction force applied. The buccal and palatal rocking movements, plus the twisting movements were also measured in this in-vivo study during premolar extraction for orthodontic purposes. Methods: The physical strains or forces transferred onto the teeth during extraction are the following three movements: gripping, twisting, and traction. A strain measurement gauge was attached onto an ordinary dentistry plier. The strain measurement gauge was constituted with an extensimetric washer with three 45º grids. The system operation was correlated to the variation of electrical resistance. Results: The variations of resistance (∆R) and all the different forces applied to the teeth (∆V) were recorded by a computerized system. Data results were processed through Microsoft Excel. The results underlined the stress distribution on the extracted teeth during gripping, twisting and flexion. Conclusions: The obtained data showed that the strength required to effect teeth extraction is not influenced by the quality of the bone but is instead influenced by the shape of the tooth’s root.

    To aid informed health sector decision-making, data from sufficient high quality economic evaluations must be available to policy makers. To date, no known study has analysed the quantity and quality of available Iranian economic evaluation studies. This study aimed to assess the quantity, quality and targeting of economic evaluation studies conducted in the Iranian context. The study systematically reviewed full economic evaluation studies (n = 30) published between 1999 and 2012 in international and local journals. The findings of the review indicate that although the literature on economic evaluation in Iran is growing, these evaluations were of poor quality and suffer from several major methodological flaws. Furthermore, the review reveals that economic evaluation studies have not addressed the major health problems in Iran. While the availability of evidence is no guarantee that it will be used to aid decision-making, the absence of evidence will certainly preclude its use. Considering the deficiencies in the data identified by this review, current economic evaluations cannot be a useful source of information for decision makers in Iran. To improve the quality and overall usefulness of economic evaluations we would recommend; 1) developing clear national guidelines for the conduct of economic evaluations, 2) highlighting priority areas where information from such studies would be most useful and 3) training researchers and policy makers in the calculation and use of economic evaluation data.

    Full Text Available There has been a wealth of investigation into the use of online multiple-choice questions as a means of summative assessment, however the research into the use of formative MCQs by the same mode of delivery still remains patchy. Similarly, research and implementation has been largely concentrated within the Sciences and Medicine rather than the more discursive subjects within the Humanities and Social Sciences. The INQUIRE (Interactive Questions Reinforcing Education Evaluation Project was jointly conducted by two groups at the University of Oxford–the Saïd Business School and the Academic Computing Development Team to evaluate the use of online MCQs as a mechanism to reinforce and extend student learning. This initial study used a small set of highly focused MCQ tests that were designed to complement an introductory series of first-year undergraduate management lectures. MCQ is a simple and well-established technology, and hence the emphasis was very much on situating the tests within the student experience. The paper will cover how the online MCQs are intended to fit into the Oxford Undergraduate study agenda, and how a simple evaluation was executed and planned to investigate their usage and impact. The chosen method of evaluation was to combine focus groups with automated online methods of tracking, and the paper discusses the findings of both of these.

    Full Text Available This paper explores the effectiveness of a recently introduced innovation subsidy program targeted at SMEs in Croatia. Three aspects of program additionality were evaluated: input, output and behavioral aspects. Both qualitative and survey research was employed, and four case studies with selected recipient companies were conducted. This study is a response to the policy-makers’ need for early program assessment. It attempts to show that even with early evaluation and small population of recipients it is possible to gain insight into program effectiveness. The analysis suggests that the effects of programs targeted at innovative SMEs might need to be evaluated differently than general subsidies. This is especially evident in the evaluation of input additionality. The analysis indicates that SMEs which started with a higher R&D capability tend to increase R&D intensity while participating in the program. The program raised R&D and innovation capability of the participating SMEs, but commercialization of project results remains a concern.

  4. Source Evaluation and Information Literacy: Findings from a Study on Science Websites

    Full Text Available An essential component of information literacy is the evaluation of information resources. Integral to evaluation are users’ judgments about which Web sources might prove reliable when learning about a particular topic and the ones that they would choose for short term and long term use. Past Website quality studies have used research methods that involved asking participants to recall quality factors without the benefit of concurrent Web searching. Users in this study evaluated Websites during live searching on the “open” or unrestricted Web in a quasi-experimental protocol to determine the quality factors they valued and how these factors relate to gaining knowledge about a particular topic – genetically modified food. Forty users from within a university setting and from the general community were given a pre-test about subject knowledge, were then asked to search and evaluate the most promising sites they found, and, subsequently, were given a post-searching questionnaire related to the quality of the information and the Websites retrieved. The quality factors that participants reported as helpful to them during the search are reported here. Two weeks later participants answered questions about the Websites they visited and what they had learned via an email survey. The participants then reported factors that allowed them to remember a Website or the information contained within it.

  5. Fundamental Study of Evaluation at Berthing Training for Pilot Trainees Using a Ship Maneuvering Simulator

    Full Text Available Use of the ship maneuvering simulator (SMS is at the core of pilot trainees education and training, so it is desirable to have an evaluation method that can be completed shortly after each berthing training session. There are basically two methods of docking maneuvering that pilot trainees learn: one in which the ship enters from outside the port and is berthed directly at the target quay, and a second method in which the vessel carries out a turn in front of the target quay before berthing. The authors suggested an evaluation index in a previous study concerning the first docking method. In the present study, the authors propose an evaluation method for the case of berthing the vessel using the turning maneuver. Since the index obtained by this method offers a single numerical benchmark, it is an easy–to-understand result of the training exercise. The authors carried out experiments using a SMS and confirmed that the proposed evaluation method is effective and helpful to improve the effectiveness of SMS training.

    by evaluating drug trafficking on one of the most well-known cryptomarkets, Silk Road 2.0. The research on cryptomarkets in general—particularly in Dolliver's article—poses a number of new questions for methodologies. This commentary is structured around a replication of Dolliver's original study....... The replication study is not based on Dolliver's original dataset, but on a second dataset collected applying the same methodology. We have found that the results produced by Dolliver differ greatly from our replicated study. While a margin of error is to be expected, the inconsistencies we found are too great...

    2016-09-01

    Full Text Available Introduction: Online education resources (OERs, like blogs and podcasts, increasingly augment or replace traditional medical education resources such as textbooks and lectures. Trainees’ ability to evaluate these resources is poor, and few quality assessment aids have been developed to assist them. This study aimed to derive a quality evaluation instrument for this purpose. Methods: We used a three-phase methodology. In Phase 1, a previously derived list of 151 OER quality indicators was reduced to 13 items using data from published consensus-building studies (of medical educators, expert podcasters, and expert bloggers and subsequent evaluation by our team. In Phase 2, these 13 items were converted to seven-point Likert scales used by trainee raters (n=40 to evaluate 39 OERs. The reliability and usability of these 13 rating items was determined using responses from trainee raters, and top items were used to create two OER quality evaluation instruments. In Phase 3, these instruments were compared to an external certification process (the ALiEM AIR certification and the gestalt evaluation of the same 39 blog posts by 20 faculty educators. Results: Two quality-evaluation instruments were derived with fair inter-rater reliability: the METRIQ-8 Score (Inter class correlation coefficient [ICC]=0.30, p<0.001 and the METRIQ-5 Score (ICC=0.22, p<0.001. Both scores, when calculated using the derivation data, correlated with educator gestalt (Pearson’s r=0.35, p=0.03 and r=0.41, p<0.01, respectively and were related to increased odds of receiving an ALiEM AIR certification (odds ratio=1.28, p=0.03; OR=1.5, p=0.004, respectively. Conclusion: Two novel scoring instruments with adequate psychometric properties were derived to assist trainees in evaluating OER quality and correlated favourably with gestalt ratings of online educational resources by faculty educators. Further testing is needed to ensure these instruments are accurate when applied by

    Full Text Available Aims: The aim of this study was to evaluate the performance of photoionization detector (PID system as a substitution for gas chromatography in the measurement of a 3 xylene isomer mixtures as a representative of the volatile organic compounds in photocatalytic studies. Materials and Methods: This study has been carried out by using test setup for generating known concentrations from equal ratio of 3 xylene isomers. The concentration values to be evaluated were classified into 4 concentration ranges from 0.1 of threshold limit values (TLV to 2 of TLV to evaluate the PID system appliance compared with that in the reference method. The test was done 4 times for each evaluation concentration in 3 relative humidity levels (0%, 20%, and 80%. Results: The correlation between the PID results and the National Institue of Occupational Safety and Health (NIOSH reference method results in an atmosphere with relative humidity of 0%, 20%, and 80% were good and, respectively, were 0.993, 0.992, and 0.991 and total correlation was 0.989. The paired t test indicates a significant difference between actual concentrations in reference method and the extracted concentration from PID. Conclusions: Although the results presented by PID in the present study are different from those extracted from the reference method (from 10 to 260 ppm, the equipment response is linear. So, the results are acceptable in photocatalytic studies in case the contaminant concentration is measured by the same equipment either before or after the reactor for calculation of the removal efficiency. PID calibration with the test material(s is recommended.

    Objectives To explore agreement among healthcare professionals assessing eligibility for work disability benefits. Design Systematic review and narrative synthesis of reproducibility studies. Data sources Medline, Embase, and PsycINFO searched up to 16 March 2016, without language restrictions, and review of bibliographies of included studies. Eligibility criteria Observational studies investigating reproducibility among healthcare professionals performing disability evaluations using a global rating of working capacity and reporting inter-rater reliability by a statistical measure or descriptively. Studies could be conducted in insurance settings, where decisions on ability to work include normative judgments based on legal considerations, or in research settings, where decisions on ability to work disregard normative considerations.Teams of paired reviewers identified eligible studies, appraised their methodological quality and generalisability, and abstracted results with pretested forms. As heterogeneity of research designs and findings impeded a quantitative analysis, a descriptive synthesis stratified by setting (insurance or research) was performed. Results From 4562 references, 101 full text articles were reviewed. Of these, 16 studies conducted in an insurance setting and seven in a research setting, performed in 12 countries, met the inclusion criteria. Studies in the insurance setting were conducted with medical experts assessing claimants who were actual disability claimants or played by actors, hypothetical cases, or short written scenarios. Conditions were mental (n=6, 38%), musculoskeletal (n=4, 25%), or mixed (n=6, 38%). Applicability of findings from studies conducted in an insurance setting to real life evaluations ranged from generalisable (n=7, 44%) and probably generalisable (n=3, 19%) to probably not generalisable (n=6, 37%). Median inter-rater reliability among experts was 0.45 (range intraclass correlation coefficient 0.86 to κ−0

    The purpose was to objectively evaluate a recently FDA-approved gadolinium-based contrast agent (GBCA) in comparison to our standard GBCA for acute adverse events and image quality by blinded evaluation. Evaluation was made of a recently FDA-approved GBCA, gadobutrol (Gadavist; Bayer), in comparison to our standard GBCA, gadobenate dimeglumine (MultiHance; Bracco), in an IRB- and HIPAA-compliant study. Both the imaging technologist and patient were not aware of the brand of the GBCA used. A total of 59 magnetic resonance studies were evaluated (59 patients, 31 men, 28 women, age range of 5-85 years, mean age of 52 years). Twenty-nine studies were performed with gadobutrol (22 abdominal and 7 brain studies), and 30 studies were performed with gadobenate dimeglumine (22 abdominal and 8 brain studies). Assessment was made of acute adverse events focusing on objective observations of vomiting, hives, and moderate and severe reactions. Adequacy of enhancement was rated as poor, fair and good by one of two experienced radiologists who were blinded to the type of agent evaluated. No patient experienced acute adverse events with either agent. The target minor adverse events of vomiting or hives, and moderate and severe reactions were not observed in any patient. Adequacy of enhancement was rated as good for both agents in all patients. Objective, blinded evaluation is feasible and readily performable for the evaluation of GBCAs. This proof-of-concept study showed that both GBCAs evaluated exhibited consistent good image quality and no noteworthy adverse events. Copyright © 2013 Elsevier Inc. All rights reserved.

    Objectives: This study was planned to evaluate the dimensional stability of elastomers during cold sterilization or immersion disinfection and also to evaluate the same, along with acrylic resin trays which are used in clinical practice. Materials and Methods: A study mold according to revised American Dental Association. Specification no. 19 was used. Polyether, polyvinyl siloxane (PVS) (heavy body), PVS (regular body) and Hydrophilic addition reaction silicon (medium body) were selected for study. 2% glutaraldehyde and 0.525% sodium hypochlorite were the disinfectants used. The study was divided into group-I and group-II. In group-I study, 24 specimens of each impression material were prepared. Eight immersed in 2% glutaraldehyde, eight in 0.525% sodium hypochlorite and rest eight allowed to dry bench cure. After 16 h, the specimens measured under Leica WILD stereomicroscope and dimensions compared with master die. In group II study, 24 specimens of the material with the least dimensional changes were prepared and adhered to 24 acrylic resin disks using tray adhesive. Same immersion procedure was followed as in group I. The data were analyzed by one-way ANOVA and Tukey's multiple tests. Results: Of four impression materials used, PVS (heavy body) was the most dimensionally stable, and Polyether was the least dimensionally stable in both the groups. Interpretation and Conclusion: Within the limitation of the study, PVS (heavy body) was most stable, and polyether was least stable of all the impression materials. PMID:26929499

    Heat shock protein 90 (Hsp90) is an emerging attractive target for the discovery of novel cancer therapeutic agents. Docking methods are powerful in silico tools for lead generation and optimization. In our mission to rationally develop novel effective small molecules against Hsp90, we predicted the potency of our designed compounds by Sybyl surflex Geom X docking method. The results of the above studies revealed that Schiff bases derived from 2,4-dihydroxy benzaldehyde/5-chloro-2,4-dihydroxy benzaldehyde demonstrated effective binding with the protein. Subsequently, a few of them were synthesized (1-10) and characterized by IR, (1)HNMR and mass spectral analysis. The synthesized molecules were evaluated for their potential to suppress Hsp90 ATPase activity by Malachite green assay. The anticancer studies were performed by 3-(4,5-dimethythiazol- 2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay method. The software generated results was in satisfactory agreement with the evaluated biological activity.

  15. The delay effect on outcome evaluation: results from an Event-related Potential study

    Directory of Open Access Journals (Sweden)

    2013-11-01

    Full Text Available Behavioral studies demonstrate that the timing of receiving gains or losses affects decision-making, a phenomenon known as temporal discounting, as participants are inclined to prefer immediate rewards over delayed ones and vice versa for losses. The present study used the event-related potential (ERP technique with a simple gambling task to investigate how delayed rewards and losses affected the brain activity in outcome evaluations made by 20 young adults. Statistical analysis revealed a larger feedback related negativity (FRN effect between loss and gain following immediate outcomes than following future outcomes. In addition, delay impacted FRN only in gain conditions, with delayed winning eliciting a more negative FRN than immediatewinning. These results suggest that temporal discounting and sign effect could be encoded in the FRN in the early stage of outcome evaluation.

    2011-01-01

    Full Text Available The aim of this preliminary study is to develop a methodology to evaluate the vascularization of fetal brain in normal and abnormal canditions by three-dimensional sonography associated to Power Doppler (3DPD, with application of Virtual Organ Computer-aided Analysis (VOCAL that allows to derive vascularization and flow indexes. In this connction, we propose a new method of standardization of the setting and the acquisition mode, choosing in different fetuses and at different gestational ages the same anatomical volumes, corresponding to five spherical regions of interest. In particular, tu study the overall vascularization of the fetal brain, we use a sphere with a diameter corresponding to the bi-parietal distance. To evaluate the regional vascularization, we identify four sampling spherical sites, two in each hemisphere. This standard technical approach according to correct morphological criteria allows to exclude from the analysis vascular territories external to the brain.

    The cynomolgus macaque is the most commonly used nonhuman primate in nonclinical toxicity testing, but the macroscopic and microscopic anatomy of the stomach in the cynomolgus macaque is poorly described. To develop a reliable sampling method for histologic evaluation of the cynomolgus macaque stomach in regulatory toxicity studies, the stomachs of control animals were prospectively evaluated using an extensive sectioning pattern. The stomach of the cynomolgus macaque differs from that described for the human stomach and has a prominent fundus that lacks parietal cells. A description of the macroscopic and microscopic anatomy is presented along with a recommended sectioning pattern for nonclinical toxicity studies and discussion of species differences. A thorough understanding of normal anatomy and species comparisons are critical to interpretation of potential toxicity findings and assessment of risk in humans.

    The range of possible malaria vaccines, against different species of Plasmodium and various stages in the life cycle of the parasite in both human host and mosquito vector, is reviewed. The importance, in a malaria-endemic area, of protection by a malaria vaccine against disease rather than infection is emphasized, and the ways by which disease prevention may be achieved are discussed. Mechanisms of production and presentation of vaccines are considered, including the importance of appropriate and more effective adjuvants. The variety of immune responses to malaria is set out and linked to both human and plasmodial genetic factors. Host genetics may also modify susceptibility to malaria through mechanisms which are not immunological. There is a need for entomological studies of the Anopheles vectors, especially but not only in preparation for transmission-blocking vaccines. This overall complexity justifies a multidimensional approach to epidemiology and field-site preparation. An iterative procedure is proposed for initial field evaluation, through adult male volunteers to community studies in immune adults and then to semi-immune school children, before evaluation in the principal target population of nonimmune young children. The outcome variables for epidemiological evaluation are specified. After this brief review of malaria vaccines, the baseline studies being undertaken by the Malaria Vaccine Epidemiology and Evaluation Project of the Papua New Guinea Institute of Medical Research in the Wosera area of East Sepik Province are discussed in some detail, and their rationale linked to the range and complexity of the malaria vaccines that have been reviewed. These studies are described under the headings of their principal components of epidemiology, parasitology, immunology, genetics and entomology.
