Diabetic retinopathy refers to vascular disease in the retina of the eye that affects patients diagnosed with diabetes. The HbA1c test is closely related to retinopathy. Therefore, an early HbA1c test may prevent or reduce the retinopathy. In this study a self-administered online questionnaire was distributed in Basrah city among diabetics to assess their awareness of the HbA1c test and its relationship to detect the retinopathy. Out of 353 (208 female, 145 male) diabetics, 179 (50.70%) had poor awareness, 119 (33.71%) had moderate awareness and 55 (15.58%) had good awareness. The total awareness score with a mean ± SD of 5.4 ± 1.2, indicating that the lack of awareness about HbA1c was related to the age (P-value = 0.001), lower level of education (P-value < 0.0001) and to the lack of awareness that the patients received from their health centers (P-value = 0.031).
Waiting for commercial vessels inside the port is one of the most important problems facing traders and offshore companies, which often lead to material losses. The ports of Basrah are characterized by continuous congestion, which leads to the diversion of ships to the ports of the neighboring countries, causing the loss of many revenues to the country. This paper emphasizes the importance of non-preemptive priority queues (with multiple servers and multiple priority classes) to the problem of congestion of ports in order to promote sustainable development of the ports of Basrah. The aim of this paper is to apply a non-preemptive priority queues at ports of Basrah and calculating the average customer waiting time for the ships at berths.
Number sense is the general comprehension of numbers, operations, and the relationships which involve numbers. Based on previous prevalence studies, there are about 3-6 % of the population who have disabilities to understand the number sense. Thus, the computer technologies and mobile games play an essential role to develop the students with number sense, as it will be a tools to improve their mathematical and logical thinking. The main goal of this paper is to design a new educational math game named as 123GO to develop a basic mathematical skills of students with number sense. This study explores the measuring consideration for the usability of proposed educational math game (123GO) by using the usability testing which adopted to assess student"s motivation towards learning basic mathematical skills. During the usability testing session, the data observations of students are recorded. The usability testing data were quantified to measure the effectiveness, efficiency and satisfaction. The results showed that students' interest when using this game to teach them basic mathematical skills.
Designing the emergency medical services systems (EMS) are important in human societies, principally in urban areas where incidents occur at a high rate due to high population density. As such, the EMS managers face the task of searching for ways to improve the performance of the systems to respond to the requirements of patients taking into consideration the budget imposed by the state. This paper proposes an extension of the Dynamic Redeployment Coverage Location (DRCL) model to locate ambulances that are offering two types of services, i.e., Advance Life Support (ALS) and Basic Life Support (BLS) for two types of incoming calls (critical and non-critical). Apart from providing coverage for the non-critical calls, the BLS acts as a "backup" for the ALS in providing coverage to critical calls. The objective is to minimize the number of ambulances while meeting a predetermined level of coverage required.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
