Relationship between the status of occupational health management and job satisfaction among farmers: A health promotion approach.

Background: Job satisfaction is one of the most important issues related to human resources in the organization which can reduce organizational productivity. In this regard, occupational health is an important science related to the health of the workforce in any organization, paying attention to it will help health promotion. The aim of the present study was to determine the relationship between the status of occupational health management and job satisfaction among farmers with a health promotion approach.

Designing and Validation of Self-Assessment Tool of Professional Competency and Its Psychometrics in the Administrators of Preschool Educational Centers.

Background: The role of preschool administrators in raising children is increasing day by day, so the purpose of this study was to detect the validity and reliability of the professional competency questionnaire and its psychometric assessment in preschool administrators.

Methods: This descriptive study was conducted on 380 preschool administrators with a minimum age of 25 and a maximum of 65 year participated in 2018. The sampling method was stratified from four regions of north, south, west and east of Tehran, Iran.

Differentiation of the Left and Right Side Interventricular Septum Function in Healthy Subjects by Vector Velocity Imaging.

Background: The present study aimed to assess and compare regional strain of the right and left sides of interventricular septum in healthy subjects using velocity vector imaging analysis due to the importance of interventricular septum and limited basic information about the exact function of the interventricular septum.

Methods: The present study was conducted on 40 healthy subjects. Echocardiography was performed in the apical 4-chamber view in the left lateral decubitus position.

Countries' experiences in reforming hospital administration structure based on the Parker and Harding model: A systematic review study.

In recent years, many reforms have been made on the structure of hospital administration, most of which are proposed by Parker-Harding models. Therefore, the purpose of this study is to systematically review global relevant experiences in reforming the hospital governance structure with emphasis on the Parker-Harding model. Required information was collected using keywords autonomization, corporatization, privatization, decentralization, reform, hospital autonomy, governance model, and structural reform in databases such as EMBASE, PubMed, Scopus, SID, MagIran, and other resources.

Theoretical Evaluation of Graphene Membrane Performance for Hydrogen Separation Using Molecular Dynamic Simulation.

The main purposes of this study are to evaluate the performance of graphene membranes in the separation/purification of hydrogen from nitrogen from a theoretical point of view using the molecular dynamic (MD) simulation method, and to present details about molecular mechanisms of selective gas diffusion through nanoscale pores of graphene membranes at the simulated set conditions. On the other hand, permeance and perm-selectivity are two significant parameters of such a membrane that can be controlled by several variables such as pressure gradient, pore density, pore layer angles etc. Hence, in this work, the hydrogen and nitrogen permeating fluxes as well as the H/N ideal perm-selectivity are investigated from a theoretical point of view in a two-layer nanoporous graphene (NPG) membrane through classical MD simulations, wherein the effects of pressure gradient, pore density, and pore angle on the NPG membrane performance are evaluated and discussed.

Patient safety walkrounds; 5 years of experience in a developing country.

Objective: Patient safety walkround (PSWR) is an appropriate technique for senior managers' participation and collaboration with frontline staff to promote safety culture in hospitals. This study was conducted to assess the 5-year PSWR experience in Shahid Mahallati Hospital in Tabriz, Iran.

Methods: This was a triangulated cross-sectional study.

Development of the Persian patient satisfaction questionnaire.

Purpose: The purpose of this paper is to explore the validity and reliability of the Persian version of the patient satisfaction questionnaire (PVPSQ). The study addressed the communication skills section of the PSQ specifically.

Design/methodology/approach: This cross-sectional study was conducted in 2015 to determine the validity and reliability of the Persian version of the patient satisfaction questionnaire (PSQ).

Electrospinning of poly(vinyl alcohol)-water-soluble quaternized chitosan derivative blend.

Defect free mats containing a cationic polysaccharide, chitosan derivative such as N-[(2-hydroxy-3-trimethylammonium)propyl] chitosan chloride (HTCC), have been prepared using electrospinning of an aqueous solution of poly(vinyl alcohol) (PVA)-HTCC blends. HTCC, a water-soluble derivative of chitosan, was synthesized via the reaction between glycidyl-trimethylammonium chloride and chitosan. Solutions of PVA-HTCC Blends were electrospun.
