Effects of training based on the health belief model on Iranian women's performance about cervical screening: A systematic review and meta-analysis

CONTEXT: Pap smear test is one of the most important actions in preventing cervical cancer. This study aimed to perform a meta-analysis on all related literature about the effects of health belief model (HBM)-based training on Pap smear screening test performance of Iranian women. METHODS: The search was performed in Scopus, PubMed, and Web of Science. Eligibility criteria were limited to English and Persian language articles with experimental or semi-experimental methods until October 2019 that evaluated the effect of HBM-based training on Iranian women's performance of Pap smear test. We excluded studies that used both cervical and breast cancer screening together. RESULTS: Twelve studies were performed on totally 1605 participants. This meta-analysis showed that all of Health Belief Model (HBM) constructs improved significantly among HBM-based trained women, perceived susceptibility (standard mean division SMD =0.785; P = 0.002; confidence interval CI = 0.005 to 1.56; Heterogeneity; P = 0.013; I2 = 97%)., perceived severity (SMD = 1.14; P = 0.001; CI = 0.66-1.62; heterogeneity; P < 0.001; I2 = 92%), perceived benefits (SMD = 1.25; P = 0.001; CI = 0.545-0.135 heterogeneity; P = 0.003; I2 = 97%), perceived barrier (SMD = 0.20; P = 0.001; CI = 0.44-1.24; heterogeneity; P < 0.001; I2 = 92%) and perceived self-efficacy (SMD = 0.638; P < 0.001; CI =1.76-0.426; heterogeneity; P < 0.001; I2 = 97%). CONCLUSION: Cervical screening education program based on the HBM can be effective on Iranian women's performance in their perceived susceptibility, perceived severity, perceived barrier, and perceived self-efficacy about Pap smear test. © 2020 Journal of Education and Health Promotion | Published by Wolters Kluwer - Medkno

Rendering CSG scenes with general antialiasing

Ray-tracing is one of the most popular techniques for rendering 3D images. Effects such as shadows, reflection, refraction and so on can be produced with this technique. However, raytracing is a point-sampling technique with well-known aliasing problems. In particular, small objects and small shadows can be hidden between rays and not be detected. No ray-tracing method, even using oversampling, can solve this problem entirely. The solution is to use an extension of ray-tracing in which the concept of the infinitesimal ray is replaced by that of the beam, which has a volume of the scene. Beam-tracing is more complex than ray-tracing: in particular because of the beam-object intersection computations. So beam-tracers are usually limited to polygonal objects. The method presented here is a beam-tracer with no explicit beam-object intersection computations; so it can be used for rendering CSG scenes with antialiasing. 1. Introduction Ray-tracing is one of the most interest..

First observation of vertically aligned cesium doped ZnO nanorods as an efficient electron transporter in polymer solar cell

Single crystalline cesium doped ZnO nanorods with homogeneous size and shape were grown hydrothermally on ITO substrates that are presented in our previous work. According to the previous work, XRD analysis showed that cesium doped ZnO nanorods are wurtzite single crystals and are grown preferentially along the c-axis. Also, the electrical conductivity of doped ZnO showed higher values for the 1% cesium, which confirmed incorporation of the cesium dopant. Cesium doped ZnO nanorods are suitable candidates for applications in solar cells. So, in this research, we employed cesium doped ZnO nanorods with the different dopant concentration in inverted polymer solar cell. By comparing the effect of doped ZnO nanorods with diverse dopant concentration (0, 0.5, 1.0, 1.5 and 2%) on the performance of devices, 1.0% cesium doped ZnO was found as the most effective doping level among the selected doping concentrations. Also, using 1.0% cesium doped ZnO nanorods, Jsc of 8.21 mA/cm2, Voc of 0.541V and Fill Factor of 63.01% were achieved, which led to power conversion efficiency of 2.80%

Objective: This article performs a systemic review of psychometric properties and factor structure of the Compulsive Internet Use Scale (CIUS), the scale for assessing Internet addiction behavior in clinics and research fields. Method: Studies measuring psychometric properties and factor structure of CIUS (original version) were searched through MEDLINE in PubMed, SCOPUS, Pub Psych, google scholar and SID & Iran medex (Iranian database). A total of 18 studies (24 samples) including 44,198subjects were reviewed in our study. Results: Based on meta-analysis for internal consistency, the pooled Cronbach�s alpha coefficient from all study was 0.47(95percent confidence interval CI, 0.46-0.49). Based on meta-analysis for internal consistency adolescence subgroup was 0.48 (95percent confidence interval CI, 0.45�0.51), and addicted to behavior addiction subgroup was 0.48 (95 percent CI, 0.44�0.51), in general population subgroup was 0.47(95percent confidence interval CI, 0.42-0.53), in university student subgroup was 0.47(95percent confidence interval CI, 0.43-0.51), in internet user was 0.45(95percent confidence interval CI, 0.43-0.47), by cultural of country for collectivistic society was 0.49(95percent confidence interval CI, 0.46-0.52), and individualistic societies was 0.46 (95 percent confidence interval CI, 0.44-0.47) and based quality assessment subgroup for study was 0.47(95percent confidence interval CI, 0.46-0.49). Discussion: Future studies should be conducted on the multiethnic population and cross-cultural designee. Future studies should be developed and reported based on the COSMIN checklist. © 2020 ANP Publishing. All rights reserved

Simulating Atmospheric Pollution Weathering on Buildings

Interactions between polluted atmosphere and materials lead to an early aging of numerous buildings and monuments. This weathering process leads to important changes in appearance, from color blackening to smallscale geometric alterations: a black crust grows onto parts of affected surfaces, depending on the geometry of the object as well as on its environment. In this paper, we present a method to simulate this very important weathering process. Our method is physically inspired and provides full control to designers, keeping plausible results. First, specific polluted zones are detected according to their real physical classification. Then, the modifications of aspect of each zone are computed. Our results demonstrate that our model matches well the observed behavior of real-world monuments and buildings affected by atmospheric pollution

Prophylactic aspirin for preventing pre-eclampsia and its complications: An overview of meta-analyses

Benefits of aspirin administration on pre-eclampsia and IUGR depend on the gestational age and dose of aspirin administration. Meta-analyses show that, to prevent preterm labor, aspirin could be administrated even after 16 weeks of gestational age. © 2020 Elsevier Lt

Texture Particles

This paper presents an analytical extension of texture synthesis techniques based on the distribution of elementary texture components. Our approach is similar to the bombing, cellular, macrostructured and lapped textures techniques, but provides the user with more control on both the texture analysis and synthesis phases. Therefore, high quality results can be obtained for a large number of structured or stochastic textures (bricks, marble, lawn, etc.). The analysis consists in decomposing textures into elementary components -- that we call "texture particles" -- and for which we analyze their specific spatial arrangements. The synthesis then consists in recomposing similar textures directly on arbitrary surfaces by taking into account the previously computed arrangements, extended to 3D surfaces. Compared to "pixel-based" analysis and synthesis methods, which have been recently generalized to arbitrary surfaces, our approach has three major advantages:( 1) it is fast, which allows the user to interactively control the synthesis process. This further allows us to propose a large number of tools, granting a high degree of artistic freedom to the user. (2) I
