تقييم لنظام تقييم أداء الموظفين الإلكتروني في المقر الرئيسي لوكالة غوث وتشغيل اللاجئين في غزة

This study aimed to evaluate e-performance assessment system in the UNRWA headquarter in Gaza in terms of the modern managerial perspectives to improve the system through giving recommendations accordingly. The analytical descriptive approach was used to evaluate the new system and its effects on performance of employees at UNRWA Gaza Field Office (GFO) to improve the E-performance system in UNRWA. 150 questionnaires were distributed amongst the GFO employees; 148 questionnaires fit for research were obtained. Therefore, the response rate of the questionnaires is equal to 98.67 %. The study found that a relatively high percentage of respondents is satisfied with the system, evaluated it to be good, and stated that the system meets the purpose it was designed for and they, remarkably, expressed their need for receiving training on how to best use the Adoption of E-Performance System (EPS). A serious concern derived from the study related to evaluating the EPS, so top management can be able to derive the benefit from the frequent feedback shared by employees. The study recommended that top management of UNRWA GFO should provide the staff with the needed trainings and skills for the new EPS to keep up with development. In addition, the system should be updated to be able to send e-mails and notifications to keep users updated and it should include hyperlinks that link users to other supporting websites. UNRWA’s top management is recommended to evaluate the system itself periodically and should involve their staff in the preparation and update of the E-Performance Measurement (EPM). Besides, UNRWA’s top management is recommended to put more effort to make the EPS as a competitive advantage for GFO and should link the results of the assessment to the internal promotions system at UNRWA. Finally, employees should be given their performance scores via intranet to know their weakness and strengths.هدفت هذه الدراسة إلى تقييم نظام تقييم الموظفين الالكتروني في مقر الأونروا الر في غزة في ظل المفاهيم الإدارية الحديثة من أجل تحديد فعاليته بغرض وضع توصيات واقتراحات من شأنها المساهمة في تحسين وتطوير النظام. قام الباحث باستخدام المبحث الوصفي التحليلي من أجل تقييم النظام ودراسة اثره على اداء الموظفين العاملين في مقر الاونروا بغزة. وقام الباحث بتصميم وتوزيع استبانة على العاملين في مقر الاونروا بقطاع غزة حيث تم تعبئة 148 استبانة من 150 استبانة تم توزيعها على كافة العاملين في مقر الاونروا بغزة. بلغت نسبة الاستعادة 98.67%.. وتمثلت نتائج الدراسة الرئيسية في أن الغالبية الكبرى من الموظفين عبروا عن رضاهم عن النظام وعن اعتقادهم بأنه حقق الغرض الذي تم تصميمه لأجله. وهنالك نسبة ملحوظة من الموظفين الذين عبروا عن حاجتهم لتدريب من أجل تحسين مهاراتهم في التعامل مع النظام. كما تبين بأنه يمكن لإدارة الاونروا بغزة الاستفادة بشكل كبير من التغذية الراجعة التي يقدمها الموظفين حول النظام. وأوصت الدراسة إدارة الاونروا بغزة تقديم التدريب اللازم لتحسين مهارات الموظفين في التعامل مع الموظفين، وكذلك تطوير وتحسين النظام لكي يصبح قادرا على ارسال رسائل الكترونية وتنبيهات للموظفين. كما ينبغي تطوير النظام لكي يحتوي على روابط تشعبية من شأنها تحويل الموظفين إلى مواقع الكترونية ذات صلة. وينبغي على إدارة الاونروا بغزة القيام بتقييم النظام نفسه بشكل دوري إلى جانب اشراك الموظفين في عملية تصميمي وتطوير وتحديث النظام. وتوصى إدارة الاونروا العمل على تطوير النظام بشكل اكبر ليصبح ميزة تنافسية تتسم بها الاونروا بين المكاتب الإقليمية الأخرى في الدول المجاورة و الربط ما بين نتائج التقييم ونظام الترقيات الداخلي الخاصة بالموظفين. واخيراً ينبغي تزويد الموظفين بنتائج التقييم الخاصة بهم لكي يتعرفوا على نقاط القوة والضعف وتحسين أداؤهم

Convergence of a proximal algorithm for solving the dual of a generalized fractional program

We propose to use the proximal point algorithm to regularize a “dual” problem of generalized fractional programs (GFP). The proposed technique leads to a new dual algorithm that generates a sequence which converges from below to the minimal value of the considered problem. At each step, the proposed algorithm solves approximately an auxiliary problem with a unique dual solution whose every cluster point gives a solution to the dual problem. In the exact minimization case, the sequence of dual solutions converges to an optimal dual solution. For a class of functions, including the linear case, the convergence of the dual values is at least linear

Age-related macular degeneration and its associated factors, in Khartoum locality, Sudan

Introduction: Age-Related Macular Degeneration (AMD or ARMD), also known as Macular Degeneration, is an eye disorder that slowly destroys sharp, central vision. The causal factors of ARMD remain a controversy. The proposed study aimed to participate in controversy in focusing on the magnitude of ARMD in tertiary hospital in Khartoum state.  Methods: A hospital-based retrospective cross sectional study design was implemented in Makkah Eye Complex. Data on ARMD was derived from an electronic data based made available to the researcher. The data in excel format was uploaded in the SPSS version 21. All the 79 cases of ARMD was retained and summarized through descriptive statistics to produce graphics and frequency tables to address the research objectives and chi square test was performed to assess the association between ARMD and gender and age. A decision role was set prior to the test to reject the null hypothesis that there was no association whenever the p value is < 0.05.Results: During the period covered by the study a total of 86,788 patients attended Makkah Eye Complex, 79 patients among those was diagnosed as Age Related Macular Degeneration disease. This represents a prevalence of Age Related Macular Degeneration (ARMD) of 0.09 % (79/86,788).Discussion: Regarding age, our findings confirmed that the condition is related to aging. It occurred earlier in our research contrary to the commonly reported years of occurrence. However, the limited data available to us indicates the need to establish an electronic patient registry to enable to describe patients sociodemographic characteristics, the disease risk factors and patient management and related outcomes

Analysis of water conveying aluminum oxide/silver nanoparticles due to mixed convection through four square cavity's variable hot (cold) walled

The present work focuses on the measurement of the general entropy and the heat exchanges that occur inside a square-shaped cavity by changing the cold and hot wall in four cases filled with a hybrid nano-liquid (Al2O3-Ag/water) with a cylinder installed inside it. After validating the model, the parametric study has been conducted based on Rayleigh number (Ra), Hartman number (Ha), Darcy number (Da), Solid volume fraction (φ) and Porosity (ε) aspects. An effective finite element method was employed to solve the problem of flow in a dimensionless form of governing equations towards flow and thermal behaviors of nanofluid which is laminar and incompressible. Using the COMSOL Multiphysics® software computer suite, the equations for energy, motion, and continuity were resolved. Nusselt number calculations are presented to quantify heat transport via mixed convection. In the case studies, the entropy generation improves regardless of where the heated wall is located, except for the third case, where it is higher than the others. The findings are demonstrated with a higher Rayleigh number Ra, average Nusselt number, and entropy production. The heat transfer rate (HTR) can be effectively adjusted by making use of the magnetic field. The process of producing entropy in the third cavity, where the hot wall mediates the right wall, is the crucial observation made through this effort

Assessment of the Antioxidant and Antimicrobial Potential of <i>Ptychotis verticillata</i> Duby Essential Oil from Eastern Morocco: An In Vitro and In Silico Analysis

Ptychotis verticillata Duby, referred to as Nûnkha in the local language, is a medicinal plant that is native to Morocco. This particular plant is a member of the Apiaceae family and has a longstanding history in traditional medicine and has been utilized for therapeutic purposes by practitioners for generations. The goal of this research is to uncover the phytochemical makeup of the essential oil extracted from P. verticillata, which is indigenous to the Touissite region in Eastern Morocco. The extraction of the essential oil of P. verticillata (PVEO) was accomplished through the use of hydro-distillation via a Clevenger apparatus. The chemical profile of the essential oil was then determined through analysis utilizing gas chromatography–mass spectrometry (GC/MS). The study findings indicated that the essential oil of P. verticillata is composed primarily of Carvacrol (37.05%), D-Limonene (22.97%), γ-Terpinene (15.97%), m-Cymene (12.14%) and Thymol (8.49%). The in vitro antioxidant potential of PVEO was evaluated using two methods: the 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical trapping assay and the ferric reducing antioxidant power (FRAP) method. The data demonstrated considerable radical scavenging and relative antioxidative power. Escherichia coli, Staphylococcus aureus, Listeria innocua, and Pseudomonas aeruginosa were the most susceptible bacterial strains tested, while Geotrichum candidum, Candida albicans, and Rhodotorula glutinis were the most resilient fungi strains. PVEO had broad-spectrum antifungal and antibacterial properties. To elucidate the antioxidative and antibacterial characteristics of the identified molecules, we applied the methodology of molecular docking, a computational approach that forecasts the binding of a small molecule to a protein. Additionally, we utilized the Prediction of Activity Spectra for Substances (PASS) algorithm; Absorption, Distribution, Metabolism, and Excretion (ADME); and Pro-Tox II (to predict the toxicity in silico) tests to demonstrate PVEO’s identified compounds’ drug-likeness, pharmacokinetic properties, the anticipated safety features after ingestion, and the potential pharmacological activity. Finally, our findings scientifically confirm the ethnomedicinal usage and usefulness of this plant, which may be a promising source for future pharmaceutical development
