| 1 | Role of bevacizumab intraocular injection in the management of neovascular glaucoma显示文摘AIM:To assess the long-term effects of intraocular bevacizumab(Avastin)injections as an adjunctive drug to manage patients with neovascular glaucoma(NVG).METHODS:A retrospective study was conducted consisting of 34 eyes with secondary NVG caused by proliferative diabetic retinopathy(n=25),ischemic central retinal vein occlusion(n=8),and retinal ischemia resulting from persistent detachment(n=1)were managed by intraocular injections of bevacizumab(1.25 mg/0.05 m L),in addition to other treatments.The main outcome measure was the change in the degree of iris neovascularization.Secondary outcomes included intraocular pressure and the number of additional interventions or antiglaucoma medications administered after injection.RESULTS:All patients were followed-up for at least 12 mo.At the last follow-up,complete regression of rubeosis irides was detectable in 13(38.2%)eyes and incomplete regression in 21 eyes(61.8%).The mean intraocular pressure was 45.32±7.185 mm Hg at baseline and significantly decreased to 26.15±5.679 mm Hg at the last follow-up visit(P=0.000005).Patients received an average of 4.97 injections.As additional treatments,12 eyes(35%)received laser photocoagulation and 6 eyes(18%)underwent retinocryopexy.No further treatment was needed in 16 eyes(47.1%).CONCLUSION:Intravitreal bevacizumab injection can have a favorable effect in controlling intraocular pressure and pain control in patients with NVG because it decreases the angiogenesis and helps to augment the results of conventional procedures.The primary cause of retinal ischemia should be always targeted. | Fawaz Al Sarireh Hamzeh Mohammad Alrawashdeh Khalid Al Zubi Khalil Al Salem | 2021 | International Journal of Ophthalmology(English edition)2021，14，6： | 4 |
| 2 | An Acceptance Model of Using Mobile-Government Services(AMGS)显示文摘In recent years,the telecommunications sector is no longer limited to traditional communications,but has become the backbone for the use of data,content and digital applications by individuals,governments and companies to ensure the continuation of economic and social activity in light of social distancing and total closure inmost countries in the world.Therefore,electronic government(e-Government)andmobile government(m-Government)are the results of technological evolution and innovation.Hence,it is important to investigate the factors that influence the intention to use m-Government services among Jordan’s society.This paper proposed a new m-Government acceptance model in Jordan(AMGS);this model combines the Information System(IS)Success Factor Model and Hofstede Cultural Dimensions Theory.The study was conducted by surveying different groups of the Jordanian community.Astructured questionnaire was used to collect data from203 respondents.Multiple regression analysis has been conducted to analyze the data.The results indicate that the significant predictors of citizen intention to use m-Government services in Jordan are Information Quality,Service Quality,Uncertainty Avoidance,and Indulgence vs.restraint.While,the results also suggest that Power Distance is not a significant predictor of citizen intention to use m-Government services. | Ahmad Althunibat Mohammad Abdallah Mohammed Amin Almaiah Nour Alabwaini Thamer Ahmad Alrawashdeh | 2022 | Computer Modeling in Engineering & Sciences2022，，5： | 1 |
| 3 | Adaptive Segmentation for Unconstrained Iris Recognition显示文摘In standard iris recognition systems,a cooperative imaging framework is employed that includes a light source with a near-infrared wavelength to reveal iris texture,look-and-stare constraints,and a close distance requirement to the capture device.When these conditions are relaxed,the system’s performance significantly deteriorates due to segmentation and feature extraction problems.Herein,a novel segmentation algorithm is proposed to correctly detect the pupil and limbus boundaries of iris images captured in unconstrained environments.First,the algorithm scans the whole iris image in the Hue Saturation Value(HSV)color space for local maxima to detect the sclera region.The image quality is then assessed by computing global features in red,green and blue(RGB)space,as noisy images have heterogeneous characteristics.The iris images are accordingly classified into seven categories based on their global RGB intensities.After the classification process,the images are filtered,and adaptive thresholding is applied to enhance the global contrast and detect the outer iris ring.Finally,to characterize the pupil area,the algorithm scans the cropped outer ring region for local minima values to identify the darkest area in the iris ring.The experimental results show that our method outperforms existing segmentation techniques using the UBIRIS.v1 and v2 databases and achieved a segmentation accuracy of 99.32 on UBIRIS.v1 and an error rate of 1.59 on UBIRIS.v2. | Mustafa AlRifaee Sally Almanasra Adnan Hnaif Ahmad Althunibat Mohammad Abdallah Thamer Alrawashdeh | 2024 | Computers, Materials & Continua2024，78，2： | 0 |
| 4 | 护士和助产士在初级保健中角色认知问卷的编制及心理测量学评价显示文摘目的编制护士和助产士在初级保健中角色认知问卷(Nurses and Midwives Perceptions of theirRoles in Primary Healthcare,NMPR-PHC),并对其进行心理测量学评价。方法采用横断面调查法,选取约旦不同的初级保健机构150名注册护士和助产士为研究对象。采用内部一致性信度、折半系数验证量表的信度,采用验证性因子分析评价量表的因子结构。结果NMPR-PHC的最终版本包含18个条目。探索性因子分析揭示了构成问卷的6个因子,分别是:医疗照护协调和跨专业协作、初级保健工作场所促进者,患者照护的管理、研究、初级保健工作场所限制和高等教育,解释了问卷总方差的66.49%。问卷的Cronbach'sα系数为0.834,各分量表Cronbach'sα系数为0.662~0.707,折半系数为0.734。结论问卷总体具有良好的心理测量学特征,可作为评估护士和助产士在初级保健中角色认知的工具。 | Tariq N·Al-Dwaikat Wafa’a Ta’an Mohammad Alrawashdeh Nesrin Abu Baker Nahla M·Al Ali | 2020 | International Journal of Nursing Sciences2020，7，4： | 0 |
