    The current study assessed pregnant women’s satisfaction with antenatal care (ANC) services at primary health care centers (PHCs) in Riyadh Cluster One. The study was conducted at 11 PHCs where the ANC initiative has been implemented. A total of 646 pregnant women were enrolled. A questionnaire was completed by participants to measure the level of satisfaction with the provided services, care, and consultation. Subsequently, the data were analyzed to determine the significant differences and conduct regression analysis. The overall satisfaction with initial triage assessment, provided services, consultation, and examination was 93.7%, 87.8%, 71.8%, and 53.9%, respectively. Regarding ANC services, education was the only statistically significant variable that influenced patient satisfaction (p p p < 0.05) were the statistically significant role players. In the regression analysis, secondary education was statistically significantly related to the provided services, consultation, and examination. Despite the satisfactory level of ANC at the selected PHCs, higher patient satisfaction could be achieved in the future by improving the consultation and examination practices. Overall satisfaction with the health care workers at PHCs is high. Incorporating implied ameliorations would enhance the quality of services and patient satisfaction

    The collective behaviour of fish schools, shoals and other swarms in nature has long inspired researchers to develop solutions for optimization problems. Instinct influences the behaviour of fish to group into schools to increase safety, enhance foraging success, and promote breeding. According to these instinctive behaviours, several fish-inspired algorithms have been introduced to solve hard problems. This paper presents a comprehensive survey of fish-inspired heuristics, exploring their evolution within the context of general optimization problems. To our knowledge, this survey is the first to cover both main fish-inspired heuristics in the literature, namely, the artificial fish swarm algorithm (AFSA) and Fish school search (FSS), in addition to other algorithms inspired by specific fish species. The review covers more than 50 papers published in the Web of Science and IEEE databases since 2000. We first review the basic fish heuristics, highlighting their advantages and drawbacks, and then detail attempts in the literature to improve their behaviour to solve complex, multi-objective and high-dimensional problems in several domains. Our work is intended to provide guidance for researchers and practitioners for the purpose of further advancing research in the area of fish-inspired heuristics. We aspire to encourage their utilization in various fields for global optimization and in real-life applications. The survey findings indicate that fish-inspired heuristics are very alive in recent literature and still have great potential. Several challenges and future research directions are also identified among the findings of this survey, which can help to enhance this vibrant line of research

    The current study investigates how university teachers decline students' requests and examines the teachers' refusal strategies from cross-cultural and interlanguage perspectives. To this end, 60 female university teachers at a private Saudi university participated in 10 role-plays which involved them in declining several students' requests. The participants consisted of three groups; 20 native speakers of American English (NSE), 20 native speakers of Saudi Arabic (NSA) and 20 native speakers of Saudi Arabic who completed the role-plays in English as non-native speakers of the language (NNSE). The role-plays were audio-recorded and transcribed. The data were coded using Beebe, Takahashi, and Uliss-Weltz's (1990) refusal model and Trosborg's (1995) model of internal modifiers. The results revealed the teachers' general preference for the use of indirect over direct refusal strategies and the American teachers' stronger tendency to use indirect and mitigating internal modifiers than Arab teachers. The results also showed that the cross-cultural differences between the American and the Arab teachers were limited and that there was no effect for negative pragmatic transfer for the NNSE. The results are interpreted in terms of relevant theoretical models and the existing literature

    Background The authors aimed to explore carpal tunnel syndrome (CTS) among electronic sports (esports) athletes, to compare hand symptoms and their severity between esports athletes and the control group and within the esports athletes, and to study the relationship between esports athletes’ variables. Material and Methods A cross-sectional survey study via telephone with systematic randomized approach was used for esport athletes sampling. Control group were non-esports athletes who do not use computer for prolonged duration. The survey consisted of sports athletes’ characteristics, hand symptoms and functions, and the Boston Carpal Tunnel Questionnaire (BCTQ). The unpaired student’s t-test, Mann-Whitney U test, and χ2 test were utilised for statistical comparison, with p &lt; 0.05. Pearson’s and Spearman’s correlation coefficient tests were used for relationship analyses. Results Eligible participants were 198 out of 229. Compared to control group, esport athletes reported more CTS (p = 0.01), and radiated pain and numbness in their hands (p = 0.05). Males complained of hand symptoms (p &lt; 0.01) and its radiation (p &lt; 0.01) more than females among esports athletes. Higher BCTQ Symptom Severity Scale (BCTQ-SSS) scores were reported for esports athletes who had been playing esports for prolonged periods compared to those who had playing recently (p = 0.003), with a moderate positive correlation (+0.59, p = 0.004). A significant moderate positive correlation was reported for BCTQ Functional Severity Symptoms (BCTQ-FSS) scores in terms of hours of playing (+0.44, p = 0.04). Esports athletes who used armrests and a PC with a controller for gaming reported less hand symptoms and had milder BCTQ scores than those who used a PC with a keyboard/mouse. Generally, esports athletes spend 5–10 h/day on gaming. Conclusions Esports athletes might be at risk of developing upper-extremity nerve compression and CTS. Prolonged playing, hours of playing, type of esports device, and using armrests are possible risk factors

    The present study aimed to compare the color stability of different types of zirconia with and without grit blasting (GB) after they were immersed in staining drinks. Two hundred and forty zirconia samples (N = 240) belonging equally to three different types of zirconia (Cercon&reg; xt multilayer, xt extra translucent, and ht high translucent) were used in this study. Forty samples from each zirconia group were roughened with GB, while the other forty remained non-GB (NGB). Eight GB and NGB zirconia samples from each sub-group were immersed in artificial saliva, coffee, protein shake, chlorhexidine mouthwash, and a soft drink. Besides chlorhexidine mouthwash (immersion time: 14 days), the samples were immersed in the liquids for 28 days. A spectrophotometer was utilized to observe the color differences (&#8710;E) at baseline (T0), 7 days post-immersion (T1), 14 days post-immersion (T2), 21 days post-immersion (T3), and 28 days post-immersion (T4). For the multilayer zirconia, the greatest &#8710;E (8.45 for GB and 5.97 for NGB samples) was observed after immersion in coffee at T4. For the extra translucent zirconia, the greatest &#8710;E (9.10 for GB and 6.81 for NGB samples) was also observed after immersion into the coffee at T4. For the high translucent zirconia, the greatest &#8710;E (4.53 for GB and 3.62 for NGB samples) was observed after immersion into the coffee at T4 and T3. Protein shake and soft drink immersion also significantly discolored some zirconia samples. Overall, GB zirconia samples presented with greater &#8710;E values than their NGB counterparts. It can be concluded that coffee immersion of zirconia samples caused a more significant discoloration (increased &#8710;E values) than any other liquid. Future clinical studies should be carried out to corroborate the current study&rsquo;s findings

Among the studied participants, 336 (63%) had used at least one HS, whereby the most commonly used HSs were ginger (74.7%), mint (72%), and cumin (66.7%). Almost 78% of HSs users did not consult any healthcare provider about their use. HSs use varied significantly between female and male participants (pConclusionThe results of this study showed that HSs usage was high among patients with chronic diseases in Saudi Arabia. Concurrent usage of HSs with drugs should be well-discussed with healthcare providers to avoid potential adverse events or drug interactions especially among patients with chronic diseases

    On design of a fine-grained access control architecture for securing iot-enabled smart healthcare systems

    The Internet of Things (IoT) is facilitating the development of novel and cost-effective applications that promise to deliver efficient and improved medical facilities to patients and health organisations. This includes the use of smart ‘things’ as medical sensors attached to patients to deliver real-time data. However, the security of patient data is an ever-present concern in the healthcare arena. In the wider deployment of IoT-enabled smart healthcare systems one particular issue is the need to protect smart ‘things’ from unauthorised access. Commonly used access control approaches e.g. Attribute Based Access Control (ABAC), Role Based Access Control (RBAC) and capability based access control do not, in isolation, provide a complete solution for securing access to IoT-enabled smart healthcare devices. They may, for example, require an overly-centralised solution or an unmanageably large policy base. To address these issues we propose a novel access control architecture which improves policy management by reducing the required number of authentication policies in a large-scale healthcare system while providing fine-grained access control. We devise a hybrid access control model employing attributes, roles and capabilities. We apply attributes for role-membership assignment and in permission evaluation. Membership of roles grants capabilities. The capabilities which are issued may be parameterised based on further attributes of the user and are then used to access specific services provided by IoT ‘things’. We also provide a formal specification of the model and a description of its implementation and demonstrate its application through different use-case scenarios. Evaluation results of core functionality of our architecture are provided.</p
