Textile’s primary hand (HV) and total hand values (THV) are very important parameters and are used to identify the quality of clothing comfort. This paper aims to predict the HV and THV of the fabrics finished with functional polymers by applying Kawabata’s translation equations. The mechanical properties were achieved using Kawabata’s fabric evaluation system (KES-F) and the inference/interpretation was drawn. Then, HV and THV predictions were performed by applying Kawabata’s translation equations of the KN-101 and KN-301 series. The KES-F result confirmed that it is possible to observe the operative finishing effect on the mechanical properties of fabrics. The prediction results show that the total quality comfort of the functional fabrics could able be estimated by the equation developed by Kawabata; the calculated errors (~0.66) were within the range of the standard deviations (~0.78) of the samples between the predicted and ranked THV. The experimental and the calculated primary hand values showed strong correlation coefficients up to ~0.98 which is significant at 0.001 confidence levels. As actual functional fabrics with various surface properties were provided to estimate their tactile comfort via the equations, the result verified that the equation is reliable for the tactile comfort evaluation and grading.

Down jacket fabric is greatly important in determining the quality of a down jacket. In order to enrich the research on fabric handle, subjective and objective evaluations were made for down jacket fabrics that were less studied. The comprehensive handle evaluation system for fabrics and yarns (CHES-FY) can be used to evaluate the tactile handle of the fabric by accurately and efficiently measuring the basic mechanical properties of the fabric. Therefore, the CHES-FY was used to link the objective evaluation with the subjective handle, so as to effectively estimate the total handle value of the down jacket fabric. Fifty-two kinds of down jacket fabrics were objectively tested through measuring 17 extracted parameters, and principal component analysis was adopted to establish the five main handle characteristics of fullness, softness, stiffness, smoothness, looseness and tightness to characterize basic style of the down jacket fabrics. The results showed that the subjective and objective results were in good agreement. These characteristics can be used as indicators to characterize fabric performance, and the principal component expression to characterize fabric handle can better predict the handle characteristics of down jacket fabrics. This also proves that the CHES-FY can quickly and accurately obtain the fabric handle value, and can also evaluate the fabric quality level.

Background: This study aimed to validate the Brazilian version of EORTC CAT Core and compare the Brazilian results with those from the original European EORTC CAT Core validation study. Methods: After validated translation, 168 cancer patients from Brazil receiving radiation therapy with or without chemotherapy was assessed. Translated EORTC CAT Core and all QLQ-C30 items were administered to patients using CHES (Computer-Based Health Evaluation System) before (T0) and after (T1) treatment initiation. The association between QLQ-C30 and CAT scores and ceiling/floor effects were estimated. Based on estimates of relative validity (cross-sectional, known-group differences and changes over time), relative sample-size requirements for CAT compared to QLQ-C30 were estimated. Results: Correlation coefficients between CAT and QLQ-C30 domains ranged from 0.63 to 0.93; except for dyspnoea, all coefficients were >0.82 (corresponding figures were 0.81–0.93 in the European study). On average across domains, floor/ceiling was reduced by 10% using CAT (9% in the European study) corresponding to a relative reduction of 32% (37% in the European study). Analyses of known-group validity and responsiveness indicated that, on average across domains, the sample-size requirements may be reduced by 17% using CAT rather than QLQ-C30, without loss of power (28% in the European study). The Brazilian sample had less symptom/quality of life impairment than the European sample, which likely explains the lower sample-size reduction using CAT when comparing with the European sample. Conclusions: The results in the Brazilian cohort were generally similar to those from the European sample and confirm the validity and usefulness of the EORTC CAT Core.

Seam quality in terms of appearance and strength were investigated for very light weight fabrics (weight less than 80 g m-1;. Seams were constructed with different sewing parameters, which included types of thread, stitch densities and needle size. Before constructing the seam for appearance and strength evaluation the mechanical properties of all fabrics were determined. The mechanical properties of 48 fabrics were determined using the Kawabata Evaluation System (KES-F), the Fabric Assurance Simple Test (FAST) and an lnstron Tensile Tester. Evaluation of seam quality was performed with respect to all the sewing parameters and the seams were ranked accordingly. The same evaluation ranking for seam appearance and strength was used for further analysis using Structural Equation Modelling (SEM) under AMOS. SEM was used to establish the relationship between seam quality with respect to appearance and strength, and fabric mechanical properties. SEM was adopted to perform confirmative analysis to identify the fabrics mechanical properties that influence seam quality. From the experimental work, it was established that seams constructed with I 00 % spun polyester thread with a ticket number of 75 gave the best ranking in terms of seam strength. This thread performed at optimum values when used with 6.5 stitches per centimetre (spcm) with a Metric needle size (Nm) of 90. For seam appearance, I 00 % spun polyester with a ticket number of 120 and Metric needle size of 80 gave the best ranking. SEM established that extensibility and shear were the main fabric mechanical properties that determine seam quality of very light weight fabrics.

<p><strong>BACKGROUND: </strong>Examination time is a key factor determining the relative value of clinical physicians’ examination and care quality. Whereas commitment <strong>‎</strong>to standard prescription principles by physicians increases the likelihood of proper treatment, its effectiveness and patients’ improvement. This study aimed to determine the relationship between outpatients’ examination time and physicians prescribing quality in teaching hospitals of Ahvaz.<strong></strong></p><p><strong>METHODS: </strong>This cross-sectional study was conducted in 550 outpatients who visited teaching hospitals of Ahvaz in 2015.<strong> </strong>The quality of the prescriptions was assessed by WHO checklist<strong>.</strong> Each prescription was scored with a score range from 0 to 21, they were divided into four equal score categories including low (0–5.25), low intermediate (5.26–10.5), high intermediate (10.5–15.75) and good (15.76–21) and using correlation and regression was analyzed.</p><p><strong>RESULTS:</strong> The total mean of examination time and commitment to prescription principles was 4.88±0.12 min and 15.92±1.14, respectively. Correlation coefficients between outpatients’ examination time and dimensions of “legibility”, “pharmaceutical form” and “medical orders”, and the total quality of prescription were significant (p˂0.005). The relationship between examination time and prescription quality confirmed with the fitting linear regression model. Increase per minute in patient’s examination by a physician, which is about 0.33 points, was added to the basic quality scores of prescription.</p><p><strong>CONCLUSION: </strong>There was<strong> </strong>a relationship between Examination time and dimensions of legibility, pharmaceutical form, and medical order. Considering commitment <strong>‎</strong>to standard prescription principles,<strong> </strong>examination time, which was declared by the Health Sector Evolution Guideline, improve physicians’ prescription quality and quality of provided services of hospitals. Therefore, providing an internet schedule for examination will be extremely helpful in organizing physicians’ examination.</p>

Abstract In this paper the use of a set of nonlinear edge-preserving filters is proposed as a pre-processing stage with the purpose to improve the quality of hyperspectral images before object detection. The capability of each nonlinear filter to improve images, corrupted by spatially and spectrally correlated Gaussian noise, is evaluated in terms of the average Improvement factor in the Peak Signal to Noise Ratio (IPSNR), estimated at the filter output. The simulation results demonstrate that this pre-processing procedure is efficient only in case the spatial and spectral correlation coefficients of noise do not exceed the value of 0.6

Providing a specific level of healthcare quality is an important and a complex issue, determined by the extent of influence of number of interrelated and predetermined factors that act at different stages throughout the continuum of healthcare activities. A final healthcare product is a complex conglomerate of goods and services being heterogeneous with a time-varying result and a pronounced individuality. Thus, healthcare managers are required to put its supporting and continuous upgrading at the core of their efforts, which in turn will result in cost reduction, good collaboration between individual professionals, improved financial performance and, ultimately, patients will be optimally serviced and their needs and expectations will be satisfied.Indicators to measure quality of medical services give an idea of their characteristics, conditions and requirements for implementation. In this respect, quality assurance in clinical laboratories is an important process involving a complex system of planned actions at all stages of laboratory analysis in order to achieve the most accurate results with the aim of achieving the most accurate result, of monitoring the effect of the treatment and prognosis of the disease in question. The high quality of laboratory medical services helps modern clinicians in their practical activities and is a guarantor of achieving an adequate healthcare outcome. The ‘Quality in Laboratory Medicine’ concept evolves over time, focusing not only on analytical accuracy but also on a broader and more comprehensive basis that takes into account all the steps of clinical and laboratory analysis, providing valuable information in the process of making clinical decisions that are subordinated entirely to the cares of the patient.All healthcare professionals under the administrative authority of the medical institution, that should guarantee the necessary resources for this process, should participate in providing and improving the quality of services. It is necessary to cover the entire organizational structure, by paying attention to the optimization of the relations between staff and patients. Healthcare managers should provide permanent monitoring and a process evaluation system at each stage, allowing options for choosing alternatives for a solution and precise selectivity, aimed at improving the quality of healthcare, in particular, clinical and laboratory activities and services.
