Diabetes is a chronic condition that is significantly impacted daily by environment. At least one in five Saudis, suffer from diabetes. “Diabetes is a pandemic of unprecedented magnitude spiraling out of control” (Boulton). Saudi Arabia ranks the second highest in the Middle East, and is the seventh in the world for the prevalence of diabetes (WHO). Diabetes mellitus (DM) has been found to be related to high mortality, morbidity accompanied by poor general health and lower quality of life. Current Saudi diabetes patients’ behaviors, practices, and beliefs regarding foot health problems such as ulcers, are not well investigated. Diabetic patients frequently utilize natural remedies and Herbs for self-medication as a part of complementary and alternative Medicine. Aim of study: To explore the widespread use of the alternative remedies in the local communities of the Western Saudi Arabia, the drives behind using and to focus on the potential adverse effects following their usage. Method: A descriptive, cross-sectional study of 386 diabetic patients with feet problems in Makkah Region, West of Saudi Arabia during the period April - June 2023. Results: Out of the 531 participants, only 386 participants reported diabetic foot disorder (DFD). Most of the participant were above 65 years of age group (24.61 %). Male (52.08%) more than female (47.92%) in the research group. All of the participants had diabetic foot disorders at least once. The prevalence of complementary and alternative medicines (CAM) use among them was 67.88%, as solitary or in combination with hospital medicines. Honey headed the list followed by myrrh and black seeds. Acquaintances advice (59.54%) was the most reason for using the alternative medicine. 60.30% of Diabetic foot patient complained of adverse effects during CAM remedies use. Conclusion: Consumption of CAM remedies among diabetic patients for Diabetic Foot Disorder (DFD) is common. Honey headed the list followed by myrrh and black seeds. Addit

Open Journal of Applied Sciences 2022年第10期12卷 1618-1631页

作者： elamin Ahmed mohammed Ahmed Department of Language & Translation University of Tabuk University College of Duba Duba Kingdom of Saudi Arabia

As we know, Pragmatics is the way we convey meaning through communication, so the study aims at student’s opinions on the use of English language as a means of communication and to show the significance of language function, context, and authentic situations to develop pragmatic competence in Sudanese English Language university learners. To achieve the objectives, the study used a questionnaire to address the study questions and objectives. 150 employed students participated in the questionnaire. The study found that the students have positive views toward the using of the language as communicative means in various, functions, contexts, and authentic situations inside and outside the classroom to enhance the student’s fluency in using the target language as well as the take care about the language forms to avoid imperfect using of the language.

作为一种新兴技术,云计算对信息技术行业产生了巨大变革,并持续受到来自公共领域和私营领域的关注。随着这种技术的不断发展及广泛应用,保持其诸如服务质量(QoS)和服务等级协议(SLA)的性能是很重要的。这也是我们选择云计算提供商的一个重要参考依据。虚拟机迁移是改善虚拟机过度整合的一种主要手段,其中过度整合可能会导致应用性能下降。本文提出一种支持基础设施即服务(IaaS)和可以避免物理机过载的动态在线迁移技术。这种技术有助于快速发展的、主流的开源云平台OpenStack性能的改善。通过对OpenStack的深入研究,其核心组件帮助我们对过量负载比例进行观察。观察发现,需要一种考虑开销的动态虚拟机迁移的技术来减少过量负载导致的问题并且可以适时提高Qos及SLA的性能。本文使用单指数平滑算法来估计物理服务器在下一阶段的负载。进一步,我们提出了一种有效的基于自适应阈值策略的分布式策略,并且该策略适合易变的工作集环境。分布在本地主机上的算法可以有效地进行检测并防止过度负载,然后使用阈值策略选择合适的虚拟机来保持低负载。此外,提出了一种不同以往的运行在控制节点的算法,该算法可以有效地将虚拟机分配到负载最小的目标物理机上。这个工作有助于Openstack云平台提供包括管理及资源分发方面的改进,并符合可扩展管理目标。本方案的实现包括：分布式算法,负载获取组件及监控组件。试验结果表明我们的系统可以在合适的时候避免过载,并且仿真结果表明我们的方法在减少SLA违反及降低虚拟机迁移次数上面能够取得很好的效果。
